    Background: Dihydropyridine calcium antagonists are largely employed for the treatment of hypertension, coronary heart disease, and heart failure. Objective: The aim of our study was to compare the antihypertensive effect of the dihydropyridine calcium antagonists barnidipine and amlodipine. Methods: This was a 24-week, randomized, open-label, pilot study. Consecutive treatment-naive patients with grade I or II essential hypertension (office sitting systolic blood pressure [BP] of 140–179 mm Hg and diastolic BP of 90–109 mm Hg) were enrolled. The primary end points were the effect of treatment with either barnidipine 10 mg or amlodipine 5 mg once daily on office and ambulatory BP, left ventricular mass index (LVMI), and markers of cardiac damage, serum procollagen type I C-terminal propeptide, and plasma amino-terminal pro-B-type natriuretic peptide concentrations. Patients were assessed at enrollment, and 12 and 24 weeks. During each visit, the prevalence of adverse events (AEs) was also monitored using spontaneous reporting, patient interview, and physical examination, the relationship to study drug being determined by the investigators. Compliance with treatment was assessed at each study visit by counting returned tablets. Results: Thirty eligible patients (20 men, 10 women; mean [SD] age, 47 [12] years) were included in the study; all patients completed the 24 weeks of study treatment. Twelve weeks after randomization, 6 patients in the amlodipine group had their dose doubled to 10 mg due to inadequate BP control. Mean BP reductions at study end were not significantly different between the barnidipine and amlodipine groups (office BP, −10.3/−9.4 vs −16.6/−9.1 mm Hg; ambulatory BP, 9.4/6.4 vs 8.1/5.1 mm Hg). Reductions in LVMI and markers of cardiac damage were not significantly different between the 2 groups. Significantly more patients in the amlodipine group reported drug-related AEs compared with those in the barnidipine group (9 [60%] vs 2 [13

    Background Although trazodone is frequently used by fibromyalgia patients, its efficacy on this disease has not been adequately studied. If effective, pregabalin, whose beneficial effects on pain and sleep quality in fibromyalgia have been demonstrated, could complement the antidepressant and anxiolytic effects of trazodone. The aim of the present study was to assess the effectiveness of trazodone alone and in combination with pregabalin in the treatment of fibromyalgia. Methods This was an open-label uncontrolled study. Trazodone, flexibly dosed (50-300 mg/day), was administered to 66 fibromyalgia patients during 12 weeks; 41 patients who completed the treatment accepted to receive pregabalin, also flexibly dosed (75-450 mg/day), added to trazodone treatment for an additional 12-week period. Outcome measures included the Fibromyalgia Impact Questionnaire (FIQ), the Pittsburgh Sleep Quality Index (PSQI), the Beck Depression Inventory (BDI), the Hospital Anxiety and Depression Scale (HADS), the Brief Pain Inventory (BPI), the Short-Form Health Survey (SF-36), and the Patients' Global Improvement scale (PGI). Emergent adverse reactions were recorded. Data were analyzed with repeated measures one-way ANOVA and paired Student's t test. Results Treatment with trazodone significantly improved global fibromyalgia severity, sleep quality, and depression, as well as pain interference with daily activities although without showing a direct effect on bodily pain. After pregabalin combination additional and significant improvements were seen on fibromyalgia severity, depression and pain interference with daily activities, and a decrease in bodily pain was also apparent. During the second phase of the study, only two patients dropped out due to side effects. Conclusions Trazodone significantly improved fibromyalgia severity and associated symptomatology. Its combination with pregabalin potentiated this improvement and the tolerability of the drugs in association was good. Trial

    Purpose This single-arm, open-label study aimed to explore the effects of extended-release paliperidone on social and cognitive function in patients with schizophrenia. Methods Paliperidone extended-release (flexible dose ranging from 3 to 12 mg/day orally) was administered for 24 weeks in patients with schizophrenia. Patient function was assessed using the personal and social performance scale, measurement and treatment research to improve cognition in schizophrenia initiative-consensus cognitive battery, positive and negative syndrome scale, and clinical global impression-severity. Results Ninety patients were included in the full analysis set, while 72 patients were included in the per protocol set. The personal and social performance score was 54.3±14.3 at baseline, and significantly increased to 73.4±12.6 at week 24 (P<0.001). For the measurement and treatment research to improve cognition in schizophrenia initiative-consensus cognitive battery assessment, six of the nine individual subtests, six of the seven cognitive domains, and total cognitive scores improved significantly (P<0.05) between baseline and endpoint. positive and negative syndrome scale total scores and clinical global impression-severity scores decreased gradually (P<0.001) from week 4 to the conclusion of the study. Conclusion Paliperidone extended-release treatment significantly improves social and neurocognitive function as well as symptoms in Chinese patients with schizophrenia. PMID:27601904

    Introduction Psoriasis is a debilitating, chronic inflammatory systemic disease affecting around 2% of the South American population. Biological therapies offer the possibility of long-term therapy with improved safety and efficacy. Methods We conducted a multicentre, open-label, single-arm, Phase IIIb/IV study of adult patients (18–75 years) with moderate-to-severe plaque psoriasis who were candidates for systemic therapy or phototherapy. Patients received efalizumab subcutaneously (1.0 mg/kg/wk). The primary endpoint was the proportion of patients achieving a Physician Global Assessment (PGA) rating of “excellent” or “cleared” at Week 24. Safety outcomes were adverse events (AEs), serious AEs (SAEs) and abnormalities on laboratory tests. Results Of 189 patients included in the intent-to-treat and safety populations, 104 (55.0%) were of Hispanic or Latino ethnicity. At Week 24, 92/189 (48.7%) patients achieved or maintained a PGA rating of “excellent” or “cleared”. AEs were reported by 161/189 (85.2%) patients, SAEs by 21/189 (11.1%). One patient died during the study (meningoencephalitis). Laboratory findings were consistent with previous experience. Conclusions Efalizumab demonstrated sustained control of psoriasis up to 24 weeks in patients from Latin America, confirming results seen in Phase III studies conducted in North America and Europe.

    Background Significant anxiety symptoms are associated with poor clinical course and outcome in major depressive disorder (MDD). This single-arm, open-label study aimed to evaluate the efficacy and tolerability of escitalopram treatment in patients with MDD and anxiety symptoms. Methods Adult patients with MDD and anxiety symptoms (Montgomery–Asberg Depression Rating Scale [MADRS] ≥22 and Hamilton Anxiety Rating Scale [HAM-A] ≥14) were enrolled and received escitalopram (10–20 mg/day) treatment for 24 weeks. Symptom status was assessed by MADRS, 17-item-Hamilton Depression Rating Scale, HAM-A, and Clinical Global Impression Scale at baseline and the following visits. Quality of life was assessed by Short Form-12, and safety was evaluated by adverse events, laboratory investigations, vital signs, and physical findings. Results Overall, 200 of 318 (66.2%) enrolled patients completed the 24-week treatment. The remission (MADRS ≤10 and HAM-A ≤7) rate in the full analysis set (N=285) was 73.3% (95% confidence interval: 67.80, 78.38) at week 24. Mean (± standard deviation) MADRS total score was 33.4 (±7.13) and HAM-A score was 27.6 (±7.26) at baseline, which reduced to 6.6 (±10.18) and 6.0 (±8.39), respectively, at week 24. Patients with higher baseline depression and anxiety level took longer to achieve similar remission rates. Overall, 80 of the 302 (26.5%) patients included in the safety set reported at least 1 treatment-emergent adverse event (TEAE). Most frequently reported TEAEs (>2%) were headache (4.0%), nasopharyngitis (3.6%), nausea (3.0%), and dizziness (2.6%). Serious TEAEs were reported by 1.3% patients; no deaths were reported. Conclusion Escitalopram 10–20 mg/day was effective and well-tolerated in the long-term treatment of MDD with anxiety symptoms in adult Chinese population. PMID:28255239

    Background We assessed the effect of switching patients with major depressive disorder to milnacipran following an initial selective serotonin reuptake inhibitor treatment failure, and explored potential biomarkers in their blood. Methods We conducted a prospective, open-label, 24-week trial. Depression was assessed with the 17-item Hamilton Depression Rating Scale. Patients showing a ≥50% reduction in Hamilton Depression Rating Scale scores from baseline to final visit were considered responders. Regarding adverse effects (AEs), moderate-to-severe AEs were specifically identified as effects that required any medical treatment or that induced treatment withdrawals. We also measured blood levels of various molecules including inflammatory cytokines. Results Of the 30 participants who enrolled, 17 completed this study. The responder rate was 30% (n=10). Baseline serum levels of interleukin-6 (Z=−2.155; P=0.031) and interleukin-8 (Z=−2.616; P=0.009) were significantly higher when moderate-to-severe AEs were present (n=13 patients with moderate-to-severe AEs). Serum levels of macrophage inflammatory protein-1β showed a significant continuous decrease from the baseline level (Friedman’s test: χ2=23.9, df=4, P<0.001) only in non-responders. Conclusion These results demonstrate that serum levels of interleukin-6, interleukin-8, and macrophage inflammatory protein-1β as potential blood biomarkers could be utilized to identify the responsiveness of patients to serotonin and norepinephrine reuptake inhibitor like milnacipran, or to identify those patients who may experience AEs strong enough to warrant discontinuation of treatment.

    Background Nifedipine gastrointestinal therapeutic system (GITS) is used to treat angina and hypertension. The authors aimed to study the early intervention impact on arterial stiffness and pulse wave velocity (PWV) independent of its blood-pressure-(BP) lowering effect in mild hypertensive patients. Methods This single-center, single-arm, open-label, prospective, Phase IV study recruited patients with mild hypertension and increased PWV from December 2013 to December 2014 (N=138; age, 18–75 years; systolic blood pressure, 140–160 mmHg; diastolic BP, 90–100 mmHg; increased brachial–ankle pulse wave velocity [baPWV, ≥12 m/s]). Nifedipine GITS (30 mg/d) was administered for 24 weeks to achieve target BP of <140/90 mmHg. The dose was uptitrated at 60 mg/d in case of unsatisfactory BP reduction after 4 weeks. Primary study end point was the change in baPWV after nifedipine GITS treatment. Hemodynamic parameters (office BP, 24-hour ambulatory BP monitoring, and heart rate and adverse events) were evaluated at baseline and followed-up at 2, 4, 8, 12, 18, and 24 weeks. Results Majority of patients (n=117; 84.8%) completed the study. baPWV decreased significantly at 4 weeks compared with baseline (1,598.87±239.82 vs 1,500.89±241.15 cm/s, P<0.001), was stable at 12 weeks (1,482.24±215.14 cm/s, P<0.001), and remained steady through 24 weeks (1,472.58±205.01 cm/s, P<0.001). Office BP reduced from baseline to week 4 (154/95 vs 136/85 mmHg) and remained steady until 24 weeks. Nifedipine GITS significantly decreased 24-hour ambulatory BP monitoring (P<0.001) after 24 weeks from baseline. Mean arterial pressure and pulse pressure were lowered significantly after 4, 12, and 24 weeks of treatment (P<0.001). These changes in baPWV were significantly correlated with changes in systolic blood pressure, diastolic BP, and mean arterial pressure (P<0.05), but not with changes in pulse pressure (P>0.05). There were no other drug-related serious adverse events. Conclusion

    Aim: The aim of the following study is to evaluate the effect of life-style modification on postmenopausal (PM) overweight and obese Indian women in a randomized controlled 24 week study. Materials and Methods: Two groups were formed Group I (n = 30) was designated as intervention (dietary and exercise group) and Group II (n = 24) served as control. Comparison of weight, waist circumference (WC) and body mass index (BMI) were made and compared among two groups at 4, 8, 16 and 24 weeks. Results: Mean age at menopause was 48.35 years versus 49.65 years; mean number of menopausal symptoms were 5.70 ± 1.76 versus 5.10 ± 1.56 and mean duration since menopause was 2.70 versus 2.90 years in Groups I and II respectively. When the effect of Group I and control on weight was compared at 4, 8, 16 and 24 weeks, there was no significant difference between them up to 8 week. At 8 weeks Group I caused a significant decrease in weight (P ≤ 0.05) when compared with control arm and which continued throughout the study period (P < 0.05) at both 16 and 24 weeks. Group I produced a significant reduction in WC from 8 weeks onwards up to 24 weeks (P ≤ 0.05). BMI was statistically significant in Group I and the effect started at 4th week (P ≤ 0.05) and the differences in BMI reduction were highly significant at 16th and 24th weeks (P ≤ 0.001). Conclusion: The results of the present study strongly recommend the life-style management to be incorporated in daily style of postmenopausal women under controlled supervision. PMID:24672202

    Abstract Objective. To assess the efficacy and safety of abatacept for secondary Sjögren's syndrome (SS) associated with rheumatoid arthritis (RA). Methods. The primary endpoint of this 1-year, open-labeled, prospective, observational multicenter study of RA-associated secondary SS was the rate of SDAI remission at 52 weeks after initiation of abatacept therapy. The secondary endpoints included that of Saxson's test and Schirmer's test. Adverse events during the study period were also analyzed. Results. Thirty-two patients (all females) were enrolled in this study. Interim analysis at 24 weeks included assessment of efficacy (n = 31) and safety (n = 32). The mean SDAI decreased from 19.8 ± 11.0 (± SD) at baseline to 9.9 ± 9.9 at 24 weeks (P < 0.05). Patients with clinical remission, as assessed by SDAI, increased from 0 patient (0 week) to 8 patients (25.8%) at 24 weeks. Saliva volume (assessed by Saxson's test) increased slightly from 2232 ± 1908 (0 week) to 2424 ± 2004 (24 weeks) mg/2 min (n = 29). In 11 patients with Greenspan grading 1/2 of labial salivary glands biopsy, saliva volume increased from 2945 ± 2090 (0 week) to 3419 ± 2121 (24 weeks) mg/2 min (P < 0.05). Schirmer's test for tear volume showed increase from 3.6 ± 4.6 (0 week) to 5.5 ± 7.1 (24 weeks) mm/5 min (n = 25; P < 0.05). Five adverse events occurred in five of 32 patients (15.6%), and three of these events were infections. Conclusion. Abatacept seems to be effective for both RA and RA-related secondary SS.

    This 6-week, randomized, open-label pilot study estimated the treatment effect size of gabapentin (n = 17) compared with bupropion SR (n = 19) for smoking cessation, thereby allowing sample size calculations for a definitive comparison study. The primary outcome measure was smoking cessation. Secondary outcome measures included smoking reduction and withdrawal severity. Gabapentin was less efficacious than bupropion for smoking cessation but was associated with fewer dropouts from adverse effects. Withdrawal severity was less with bupropion. Bupropion remains the first-line non-nicotine pharmacotherapy for smoking cessation. Further study is required to determine if gabapentin has any useful role in smoking cessation. Based on our primary outcome measure, 79 subjects would be required in each treatment group of a two-armed study to achieve 90% power for detecting a difference in efficacy between gabapentin and bupropion.

    Abstract This randomized controlled trial was performed to investigate whether placebo effects in chronic low back pain could be harnessed ethically by adding open-label placebo (OLP) treatment to treatment as usual (TAU) for 3 weeks. Pain severity was assessed on three 0- to 10-point Numeric Rating Scales, scoring maximum pain, minimum pain, and usual pain, and a composite, primary outcome, total pain score. Our other primary outcome was back-related dysfunction, assessed on the Roland–Morris Disability Questionnaire. In an exploratory follow-up, participants on TAU received placebo pills for 3 additional weeks. We randomized 97 adults reporting persistent low back pain for more than 3 months' duration and diagnosed by a board-certified pain specialist. Eighty-three adults completed the trial. Compared to TAU, OLP elicited greater pain reduction on each of the three 0- to 10-point Numeric Rating Scales and on the 0- to 10-point composite pain scale (P < 0.001), with moderate to large effect sizes. Pain reduction on the composite Numeric Rating Scales was 1.5 (95% confidence interval: 1.0-2.0) in the OLP group and 0.2 (−0.3 to 0.8) in the TAU group. Open-label placebo treatment also reduced disability compared to TAU (P < 0.001), with a large effect size. Improvement in disability scores was 2.9 (1.7-4.0) in the OLP group and 0.0 (−1.1 to 1.2) in the TAU group. After being switched to OLP, the TAU group showed significant reductions in both pain (1.5, 0.8-2.3) and disability (3.4, 2.2-4.5). Our findings suggest that OLP pills presented in a positive context may be helpful in chronic low back pain. PMID:27755279

    Background Calcineurin inhibitor–associated nephrotoxicity and other adverse events have prompted efforts to minimize/eliminate calcineurin inhibitor use in kidney transplant recipients. Methods This open-label, randomized, multinational study evaluated the effect of planned transition from tacrolimus to sirolimus on kidney function in renal allograft recipients. Patients received tacrolimus-based immunosuppression and then were randomized 3 to 5 months posttransplantation to transition to sirolimus or continue tacrolimus. The primary end point was percentage of patients with 5 mL/min per 1.73 m2 or greater improvement in estimated glomerular filtration rate from randomization to month 24. Results The on-therapy population included 195 patients (sirolimus, 86; tacrolimus, 109). No between-group difference was noted in percentage of patients with 5 mL/min per 1.73 m2 or greater estimated glomerular filtration rate improvement (sirolimus, 34%; tacrolimus, 42%; P = 0.239) at month 24. Sirolimus patients had higher rates of biopsy-confirmed acute rejection (8% vs 2%; P = 0.02), treatment discontinuation attributed to adverse events (21% vs 3%; P < 0.001), and lower rates of squamous cell carcinoma of the skin (0% vs 5%; P = 0.012). Conclusions Our findings suggest that renal function improvement at 24 months is similar for patients with early conversion to sirolimus after kidney transplantation versus those remaining on tacrolimus.

    Abstract Objectives: The objective of this study is to evaluate the effects of a soy drink with a high concentration of isoflavones (ViveSoy®) on climacteric symptoms. Methods: An open-label, controlled, crossover clinical trial was conducted in 147 peri- and postmenopausal women. Eligible women were recruited from 13 Spanish health centers and randomly assigned to one of the two sequence groups (control or ViveSoy®, 500 mL per day, 15 g of protein and 50 mg of isoflavones). Each intervention phase lasted for 12 weeks with a 6-week washout period. Changes on the Menopause Rating Scale and quality of life questionnaires, as well as lipid profile, cardiovascular risk and carbohydrate and bone metabolism were assessed. Statistical analysis was performed using a mixed-effects model. Results: A sample of 147 female volunteers was recruited of which 90 were evaluable. In both sequence groups, adherence to the intervention was high. Regular consumption of ViveSoy® reduced climacteric symptoms by 20.4% (p = 0.001) and symptoms in the urogenital domain by 21.3% (p < 0.05). It also improved health-related quality life by 18.1%, as per the MRS questionnaire (p <0.05). Conclusion: Regular consumption of ViveSoy® improves both the somatic and urogenital domain symptoms of menopause, as well as health-related quality of life in peri- and postmenopausal women.

    A two-arm randomized open labeled controlled clinical trial was conducted on 50 patients with non-alcoholic fatty liver disease (NAFLD). Participants were assigned to take either a lifestyle modification (LM), or LM +30 g/day brown milled flaxseed for 12 weeks. At the end of the study, body weight, liver enzymes, insulin resistance and hepatic fibrosis and steatosis decreased significantly in both groups (p< 0.05); however, this reduction was significantly greater in those who took flaxseed supplementation (p < 0.05). The significant mean differences were reached in hepatic markers between flaxseed and control group, respectively: ALT [-11.12 compared with -3.7 U/L; P< 0.001], AST [-8.29 compared with -4 U/L; p < 0.001], GGT [-15.7 compared with -2.62 U/L; p < 0.001], fibrosis score [-1.26 compared with -0.77 kPa; p = 0.013] and steatosis score [-47 compared with -15.45 dB/m; p = 0.022]. In conclusion, flaxseed supplementation plus lifestyle modification is more effective than lifestyle modification alone for NAFLD management.

    Background & objectives: Randomized controlled trials in developed countries have reported benefits of Lactobacillus GG (LGG) in the treatment of acute watery diarrhoea, but there is paucity of such data from India. The study was aimed to evaluate the efficacy and safety of Lactobacillus GG in the treatment of acute diarrhoea in children from a semi-urban city in north India. Methods: In this open labelled, randomized controlled trial 200 children with acute watery diarrhoea, aged between 6 months to 5 years visiting outpatient department and emergency room of a teaching hospital in north India were enrolled. The children were randomized into receiving either Lactobacillus GG in dose of 10 billion cfu/day for five days or no probiotic medication in addition to standard WHO management of diarrhoea. Primary outcomes were duration of diarrhoea and time to change in consistency of stools. Results: Median (inter quartile range) duration of diarrhoea was significantly shorter in children in LGG group [60 (54-72) h vs. 78 (72-90) h; P<0.001]. Also, there was faster improvement in stool consistency in children receiving Lactobacillus GG than control group [36 (30-36) h vs. 42 (36-48) h; P<0.001]. There was significant reduction in average number of stools per day in LGG group (P<0.001) compared to the control group. These benefits were seen irrespective of rotavirus positivity in stool tests. Interpretation & conclusions: Our results showed that the use of Lactobacillus GG in children with acute diarrhoea resulted in shorter duration and faster improvement in stool consistency as compared to the control group.

    Radical cure of Plasmodium vivax infection applies blood schizontocidal therapy against the acute attack and hypnozoitocidal therapy against later relapse. Chloroquine and primaquine have been used for 60 years in this manner. Resistance to chloroquine by the parasite now requires partnering other blood schizontocides with primaquine. However, the safety and efficacy of primaquine against relapse when combined with other drugs have not been demonstrated. This randomized, open-label, and relapse-controlled trial estimated the efficacy of primaquine against relapse when administered with quinine or dihydroartemisinin-piperaquine for treatment of the acute infection. Among 650 soldiers who had returned to their malaria-free base in Java, Indonesia, after 12 months in malarious Papua, Indonesia, 143 with acute P. vivax malaria were eligible for study. One hundred sixteen enrolled subjects were randomized to these treatments: artesunate (200-mg dose followed by 100 mg/day for 6 days), quinine (1.8 g/day for 7 days) plus concurrent primaquine (30 mg/day for 14 days), or dihydroartemisinin (120 mg) plus piperaquine (960 mg) daily for 3 days followed 25 days later by primaquine (30 mg/day for 14 days). Follow-up was for 12 months. One hundred thirteen subjects were analyzable. Relapse occurred in 32 of 41 (78%) subjects administered artesunate alone (2.71 attacks/person-year), 7 of 36 (19%) administered quinine plus primaquine (0.23 attack/person-year), and 2 of 36 (6%) administered dihydroartemisinin-piperaquine plus primaquine (0.06 attack/person-year). The efficacy of primaquine against relapse was 92% (95% confidence interval [CI] = 81% to 96%) for quinine plus primaquine and 98% (95% CI = 91% to 99%) for dihydroartemisinin-piperaquine plus primaquine. Antirelapse therapy with primaquine begun a month after treatment of the acute attack with dihydroartemisinin-piperaquine proved safe and highly efficacious against relapse by P. vivax acquired in Papua, Indonesia.

    Background Patients with schizophrenia suffer high rates of metabolic derangements on some antipsychotic medications that predispose them to cardiovascular diseases. Keeping this fact in mind, we planned this open-label study to see the effect on various metabolic parameters after switching stable schizophrenia subjects, who had developed metabolic syndrome on olanzapine, to aripiprazole. Methods Sixty-two patients with schizophrenia who were stable on olanzapine and were fulfilling modified National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP-III) criteria for the presence of metabolic syndrome were enrolled on the study. Patients were randomly assigned either to switch to aripiprazole or to stay on olanzapine, on a 1:1 basis. Cross-tapering over a period of 1 month was done while switching patients to aripiprazole. Laboratory assessment for metabolic parameters was done at baseline, 8 weeks, and 24 weeks after enrollment; efficacy assessment was done using the Positive and Negative Syndrome Scale (PANSS) at baseline and 24 weeks, the Clinical Global Impressions severity subscale (CGI-S) at baseline, and the Clinical Global Impressions improvement subscale (CGI-I) at 24 weeks. Results All parameters of metabolic syndrome (waist circumference, blood pressure, triglyceride level, fasting blood glucose, and high-density lipoprotein cholesterol) kept deteriorating in the stay group, compared with a continuous improvement in the switch group over time. At the end of the study, 26 patients (100%) from the stay group and 15 patients (42.8%) from switch group met the modified NCEP ATP-III criteria for presence of metabolic syndrome (P<0.001). There were no statistically significant differences between groups in psychopathology changes as measured by the PANSS total score and CGI-I scores. Conclusion Clinically stable patients with schizophrenia who are taking olanzapine and who have evidence of metabolic syndrome can be successfully switched to

    In this randomized, open-label, 8-week comparative study, the efficacy and safety of venlafaxine and fluoxetine were assessed in outpatients with major depression. One hundred forty-five patients were assigned to receive venlafaxine 37.5 mg twice daily or fluoxetine 20 mg once daily. On day 15, if clinically indicated to improve patient response, the dosage could be increased at the investigator's discretion to venlafaxine 75 mg twice daily or fluoxetine 40 mg once daily. One hundred forty-five patients were evaluated for safety and 110, for efficacy. The mean age was 37 years, and 70% of the patients were female. In both treatment groups, mean scores on the Hamilton Depression Rating Scale decreased significantly between baseline (27.8, venlafaxine; 29.2, fluoxetine) and the end of the study (8.7, venlafaxine; 8.2, fluoxetine). Similarly, mean scores on the Montgomery-Asberg Depression Rating Scale decreased significantly between baseline (31.4, venlafaxine; 31.6, fluoxetine) and the end of the study (8.3, venlafaxine; 7.6, fluoxetine). In venlafaxine patients, the most common adverse events were nausea (44.3%), headache (40.0%), insomnia (31.4%), dizziness (30.0%), and dry mouth (22.9%); in fluoxetine patients, they were headache (32.0%), nausea (28.0%), insomnia (24.0%), anxiety (21.3%), sleepiness (20.0%), and generalized tremor (20.0%). The results of this study indicate that venlafaxine is effective and well tolerated for the treatment of major depression at doses of 37.5 or 75 mg twice daily and not significantly different from fluoxetine 20 or 40 mg once daily.

    Background: Traditionally propofol has been used for providing sedation in dilatation and curettage (D and C). Recently, dexmedetomidine has been tried, but very little evidence exists to support its use. Aims: The aim was to compare hemodynamic and recovery profile of both the drugs along with a degree of comfort experienced by patients and the usefulness of the drug to surgeons. Settings and Design: Tertiary care center and open-label randomized controlled trial. Materials and Methods: Patients posted for D and C were enrolled in two groups (25 each). Both groups received fentanyl 1 μg/kg intravenous (IV) at the beginning of the procedure. Group P received IV propofol in dose of 1.5 mg/kg over 10-15 min and Group D received dexmedetomidine at a loading dose of 1 μg/kg over 10 min, followed by 0.5 μg/kg/h infusion until Ramsay sedation score reached 3-4. Hemodynamic vitals were compared during and after the procedure. In the recovery room time to reach modified Aldrete score (MAS) of 9-10 and patient's and surgeon's satisfaction scores were also recorded and compared. Results: In Group D, patients had statistically significant lower heart rate at 2, 5, 10 and 15 min as compared to Group P. Hypotension was present in 52% in Group P and 4% in Group D (P < 0.05). MAS of 9-10 was achieved in 4.4 min in subjects in Group D in contrast to 16.2 min in Group P (P < 0.05). Group D showed higher patient and surgeon satisfaction scores (P < 0.05). Conclusion: Dexmedetomidine provide better hemodynamic and recovery profile than propofol. It can be a superior alternative for short surgical day care procedures. PMID:26240542

    Recently, results of several cardiovascular clinical trials conducted in Japan were published. Most of them were designed as prospective randomized open-label blinded end-point (PROBE)-type trials, in which patients were randomly allocated to different regimens and both the patients and doctors are aware of the regimen being administered. Although the PROBE design enables performing trials resembling real-world practices, entails low costs and renders patient recruitment easier, it presents several conditions that have to be satisfied to acquire accurate results, due to its open-label nature. Principally, the so-called hard end points, which are judged by objective criteria, should be used as primary end points in order to prevent biases. In this article, a general description of various designs of clinical studies is provided, followed by a description of the PROBE design, and the precautions to be taken while conducting PROBE-designed trials by comparing trials conducted in Japan and the West.

    Gabapentin was compared with phenobarbital for the treatment of alcohol withdrawal in a randomized, open-label, controlled trial in 27 inpatients. There were no significant differences in the proportion of treatment completers between treatment groups or the proportion of patients in each group requiring rescue medication for breakthrough signs and symptoms of alcohol withdrawal. There were no significant treatment differences in withdrawal symptoms or psychological distress, nor were there serious adverse events. These findings suggest that gabapentin may be as effective as phenobarbital in the treatment of alcohol withdrawal. Given gabapentin's favorable pharmacokinetic profile, further study of its effectiveness in treating alcohol withdrawal is warranted.

    Background. Litramine (IQP-G-002AS) was shown to be effective and safe for weight loss in overweight and obese subjects. However, long-term effectiveness on maintenance of body weight loss has yet to be ascertained. Objective. To assess effect of Litramine on maintenance of body weight loss. Methods. A double-blind, randomised, placebo-controlled trial on overweight and obese patients was conducted over two sites in Germany for 24 weeks. Subjects with documented previous weight loss of 3% over the last 3–6 months were randomised to groups given either Litramine (3 g/day) or a matching placebo. Primary endpoints were difference of mean body weight (kg) between baseline and end of study and maintenance of initially lost body weight in verum group, where maintenance is defined as ≤1% weight gain. Results. Subjects who were taking Litramine lost significantly more body weight compared to the subjects taking placebo who gained weight instead (−0.62 ± 1.55 kg versus 1.62 ± 1.48 kg, p < 0.001). More importantly, 92% of subjects in Litramine group were able to maintain their body weight after initial weight loss, versus 25% in placebo group. No serious adverse events were reported throughout. Conclusion. Litramine is effective and safe for long-term body weight maintenance. Trial Registration. This trial is registered with Clinicaltrials.gov identifier: NCT01505387. PMID:26435849

    The objective of this study was to assess the safety and efficacy of itolizumab with methotrexate in active rheumatoid arthritis (RA) patients who had inadequate response to methotrexate. In this open-label, phase 2 study, 70 patients fulfilling American College of Rheumatology (ACR) criteria and negative for latent tuberculosis were randomized to four arms: 0.2, 0.4, or 0.8 mg/kg itolizumab weekly combined with oral methotrexate, and methotrexate alone (2:2:2:1). Patients were treated for 12 weeks, followed by 12 weeks of methotrexate alone during follow-up. Twelve weeks of itolizumab therapy was well tolerated. Forty-four patients reported adverse events (AEs); except for six severe AEs, all others were mild or moderate. Infusion-related reactions mainly occurred after the first infusion, and none were reported after the 11th infusion. No serum anti-itolizumab antibodies were detected. In the full analysis set, all itolizumab doses showed evidence of efficacy. At 12 weeks, 50 % of the patients achieved ACR20, and 58.3 % moderate or good 28-joint count Disease Activity Score (DAS-28) response; at week 24, these responses were seen in 22 and 31 patients. Significant improvements were seen in Short Form-36 Health Survey and Health Assessment Questionnaire Disability Index scores. Overall, itolizumab in combination with methotrexate was well tolerated and efficacious in RA for 12 weeks, with efficacy persisting for the entire 24-week evaluation period.

    Piroxicam is a NSAID with analgesic and antipyretic properties, used for the treatment of rheumatoid diseases. The aim of this study was to evaluate the bioequivalence of two brands of piroxicam capsules (20 mg) in 24 Egyptian volunteers. The in vivo study was established according to a single-center, randomized, single-dose, laboratory-blinded, 2-period, 2-sequence, crossover study with a washout period of 3 weeks. Under fasting conditions, 24 healthy male volunteers were randomly selected to receive a single oral dose of one capsule (20 mg) of either test or reference product. Plasma samples were obtained over a 144-hour interval and analyzed for piroxicam by HPLC with UV detection. The pharmacokinetic parameters Cmax , tmax , AUC0-t , AUC0-∞ , Vd /F, Cl/F, and t1/2 were determined from plasma concentration-time profiles. The 90% confidence intervals for the ratio of log transformed values of Cmax , AUC0-t , and AUC0-∞ of the two treatments were within the acceptable range (0.8-1.25) for bioequivalence. From PK perspectives, the two piroxicam formulations were considered bioequivalent, based on the rate and extent of absorption. No adverse events occurred or were reported after a single 20-mg piroxicam and both formulations were well-tolerated.

    The effect of Shenfu on biochemical parameters and survival during resuscitation in patients with septic shock was examined. This was a multicenter, controlled, randomized, open-label trial carried out in 210 patients with septic shock from seven medical centers in China. They were randomized to Shenfu or saline. The primary outcome was lactate clearance. The secondary outcomes were shock index normalization, dose of vasopressors, ICU stay, hospital stay, and mortality. A total of 199 patients completed the trial. Blood pressure, heart rate, and other routine lab tests showed no difference between the groups. Lactate levels and lactate clearance were similar between the two groups. Hospital and ICU stay were similar between the two groups. When considering all patients, the 7- and 28-day mortality were similar between the two groups, but when considering only patients with lactate levels ≥4.5 mmol/L, the Shenfu group showed a better 7-day survival than the control group (7 days: 83.3% versus 54.5%, P = 0.034; 28 days: 72.7% versus 47.6%, P = 0.092). Shenfu may improve the 7-day survival in patients with impaired lactate clearance (≥4.5 mmol/L), but the mechanism for this effect is unclear. Additional studies are necessary to characterize the hemodynamic changes after Shenfu infusion. This trial is registered with ChiCTR-TRC-11001369. PMID:27446222

    Background At present there are several kinds of medicine for treating acute gout arthritis (AGA). This study compared the efficacy and safety of prednisolone, etoricoxib, and indomethacin in the treatment of AGA. Material/Methods This was an open-label, randomized, active-comparator study in patients with AGA. Patients were randomized to 4 days of prednisolone 35 mg qd, etoricoxib 120 mg qd, or indomethacin 50 mg tid. The primary efficacy endpoint was the reduction of self-assessed pain in the index joint from baseline. Secondary endpoints included changes in physician’s assessment of tenderness, erythema, swelling, and joint activity; patient assessment of response to therapy; and safety. Results We analyzed 113 patients. Baseline demographics were comparable among treatment groups. Oral prednisolone, etoricoxib, and indomethacin were similarly effective in improving pain, tenderness, and joint activity over 4 days. For inflammation, oral prednisolone, etoricoxib, and indomethacin were similarly effective in reducing erythema, but prednisolone might be more effective in reducing swelling than indomethacin. The patient response to therapy was similar in the 3 groups. There were more total adverse events with indomethacin compared with the other 2 drugs. Conclusions Efficacy was comparable among prednisolone, etoricoxib, and indomethacin for the treatment of AGA. Prednisolone might be more effective in reducing inflammation and it had a better safety profile. PMID:26965791

    Background Increased oxidative stress and inflammation are associated with aging, and contribute to an increased risk of chronic disease in older adults. Flaxseed lignans demonstrate antioxidant and anti-inflammatory activity, but their ability to reduce oxidative stress and inflammation markers in older adult populations has received limited investigation. Objective This is a chronic intervention trial of community-dwelling healthy older adults to examine the effects of a flaxseed lignan (secoisolariciresinol diglucoside; SDG) enriched supplement (BeneFlax) compared to a placebo. The primary aim was to demonstrate the safety of BeneFlax and confirm its anti-inflammatory efficacy on markers of oxidative stress and inflammation, and subsequent functional outcomes, including those associated with its anti-inflammatory efficacy. A secondary aim was to determine flaxseed lignan metabolite concentrations in blood. Methods A double-blind randomized clinical trial was conducted. Subjects were healthy community-dwelling adults aged 60-80 years. Testing was performed at baseline, 8, 16, and 24 weeks. The 24-week intervention consisted of 600 milligrams (mg) of SDG daily or an equivalent amount (volume) of placebo. All participants received 1000 international units of vitamin D to ensure adequate vitamin D status. Measurements consisted of blood pressure, hematology, and tolerability for safety assessments; blood oxidative stress and inflammatory biomarkers for efficacy; and cognition, muscle strength, and pain as functional outcomes. Secondary endpoints of plasma levels of lignan metabolites were analyzed by mass spectrometry. Other tests, such as bone turnover markers and fecal levels of flax cyclolinopeptides, will be performed at a later date. Results Thirty-two participants were recruited (19 intervention and 13 control) and all completed the trial. Numerous Health Canada-imposed exclusion criteria limited recruitment success. Analyses are ongoing, but the baseline data

    Background We compared the time to discontinuation due to lack of tolerability over 24 weeks in patients suffering from schizophrenia treated with pomaglumetad methionil (LY2140023 monohydrate, the prodrug of metabotropic glutamate 2/3 receptor agonist, LY404039) or standard of care (SOC: olanzapine, risperidone, or aripiprazole). Methods Study HBBR was a multicenter, randomized, open-label study comparing the long-term safety and tolerability of LY2140023 with SOC for schizophrenia. Patients had moderate symptomatology with prominent negative symptoms and evidence of functional impairment. Those who met entry criteria were randomized to open-label treatment with either LY2140023 (target dose: 40 mg twice daily [BID]; n = 130) or SOC (n = 131). Results There was no statistically significant difference between LY2140023 and SOC for time to discontinuation due to lack of tolerability (primary objective; P = .184). The Kaplan-Meier estimates revealed comparable time to event profiles. Only 27% of LY2140023 and 45% of SOC patients completed the 24-week open-label, active treatment phase. Twenty-seven patients (20.8%) in the LY2140023 group and 15 patients (11.5%) in the SOC group discontinued due to lack of efficacy (P = .044). Twenty-three patients (17.7%) in the LY2140023 group and 19 patients (14.5%) in the SOC group discontinued due to adverse events (physician and subject decision combined, P = .505). The incidence of serious adverse events was comparable between groups. LY2140023-treated patients reported significantly more treatment-emergent adverse events of vomiting, agitation, and dyspepsia, while SOC-treated patients reported significantly more akathisia and weight gain. The incidence of treatment-emergent parkinsonism (P = .011) and akathisia (P = .029) was significantly greater in SOC group. Improvement in PANSS total score over the initial 6 to 8 weeks of treatment was similar between groups, but improvement was

    Objective Patients suffering from psychosis are more likely than the general population to commit aggressive acts, but the therapeutics of aggressive behavior are still a matter of debate. Methods This pilot randomized, open-label study compared the efficacy of quetiapine versus olanzapine in reducing impulsive and aggressive behaviors (primary endpoints) and psychotic symptoms (secondary endpoints) from baseline to days 1, 7, 14, 28, 42, 56, and 70, in 15 violent schizophrenic patients hospitalized in a maximum-security psychiatric hospital. Results Quetiapine (525±45 mg) and olanzapine (18.5±4.8 mg) were both efficacious in reducing Impulsivity Rating Scale from baseline to day 70. In addition, both treatments reduced the Brief Psychiatric Rating Scale, Positive and Negative Syndrome Scale, and Clinical Global Impression Scale scores at day 70 compared to baseline, and no differences were observed between treatments. Moreover, quetiapine, but not olanzapine, yielded an improvement of depressive symptoms in the items “depression” in Brief Psychiatric Rating Scale and “blunted affect” in Positive and Negative Syndrome Scale. Modified Overt Aggression Scale scores were also decreased from baseline to the endpoint, but due to the limited number of patients, it was not possible to detect a significant difference. Conclusion In this pilot study, quetiapine and olanzapine equally decreased impulsive and psychotic symptoms after 8 weeks of treatment. Double-blind, large studies are needed to confirm the validity of these two treatments in highly aggressive and violent schizophrenic patients. PMID:24855361

    Steroid-dependent nephrotic syndrome (SDNS) carries a high risk of toxicity from steroids or steroid-sparing agents. This open-label, noninferiority, randomized controlled trial at four sites in Italy tested whether rituximab is noninferior to steroids in maintaining remission in juvenile SDNS. We enrolled children age 1–16 years who had developed SDNS in the previous 6–12 months and were maintained in remission with high prednisone doses (≥0.7 mg/kg per day). We randomly assigned participants to continue prednisone alone for 1 month (control) or to add a single intravenous infusion of rituximab (375 mg/m2; intervention). Prednisone was tapered in both groups after 1 month. For noninferiority, rituximab had to permit steroid withdrawal and maintain 3-month proteinuria (mg/m2 per day) within a prespecified noninferiority margin of three times the levels among controls (primary outcome). We followed participants for ≥1 year to compare risk of relapse (secondary outcome). Fifteen children per group (21 boys; mean age, 7 years [range, 2.6–13.5 years]) were enrolled and followed for ≤60 months (median, 22 months). Three-month proteinuria was 42% lower in the rituximab group (geometric mean ratio, 0.58; 95% confidence interval, 0.18 to 1.95 [i.e., within the noninferiority margin of three times the levels in controls]). All but one child in the control group relapsed within 6 months; median time to relapse in the rituximab group was 18 months (95% confidence interval, 9 to 32 months). In the rituximab group, nausea and skin rash during infusion were common; transient acute arthritis occurred in one child. In conclusion, rituximab was noninferior to steroids for the treatment of juvenile SDNS. PMID:25592855

    The antifracture efficacy of vitamin D in osteoporosis is due to its direct action on bones and indirect extraskeletal effects to prevent falls. Eldecalcitol is an analog of active vitamin D3 that improves bone mineral density and reduces the risk of osteoporotic fractures. However, the effects of eldecalcitol on muscle strength and static and dynamic postural balance are unclear. In this open-label randomized controlled study, we assessed the effects of eldecalcitol on muscle strength and static and dynamic postural balance in 50 postmenopausal women (mean age 74 years) with osteoporosis treated with bisphosphonate. Participants were randomly divided into a bisphosphonate group (alendronate at 35 mg/week; n = 25) or an eldecalcitol group (eldecalcitol at 0.75 μg/day and alendronate at 35 mg/week; n = 25) and were followed up for 6 months. Trunk muscle strength, including back extensor strength and iliopsoas muscle strength, was measured. Static standing balance was evaluated and the one leg standing test was performed to assess static postural balance. Dynamic sitting balance was evaluated and the 10-m walk test, functional reach test, and timed up and go test were performed to assess dynamic postural balance. At 6 months, there were no significant changes in any measure of muscle strength or balance in the bisphosphonate group, whereas eldecalcitol significantly increased back extensor strength (p = 0.012) and iliopsoas muscle strength (p = 0.035). Eldecalcitol also significantly improved findings on the timed up and go test (p = 0.001) and dynamic sitting balance (p = 0.015) at 6 months. These results with eldecalcitol may have an impact on prevention of falls.

    Background Fluoroquinolones are the most commonly used group of antimicrobials for the treatment of enteric fever, but no direct comparison between two fluoroquinolones has been performed in a large randomised trial. An open-label randomized trial was conducted to investigate whether gatifloxacin is more effective than ofloxacin in the treatment of uncomplicated enteric fever caused by nalidixic acid-resistant Salmonella enterica serovars Typhi and Paratyphi A. Methodology and Principal Findings Adults and children clinically diagnosed with uncomplicated enteric fever were enrolled in the study to receive gatifloxacin (10 mg/kg/day) in a single dose or ofloxacin (20 mg/kg/day) in two divided doses for 7 days. Patients were followed for six months. The primary outcome was treatment failure in patients infected with nalidixic acid resistant isolates. 627 patients with a median age of 17 (IQR 9–23) years were randomised. Of the 218 patients with culture confirmed enteric fever, 170 patients were infected with nalidixic acid-resistant isolates. In the ofloxacin group, 6 out of 83 patients had treatment failure compared to 5 out of 87 in the gatifloxacin group (hazard ratio [HR] of time to failure 0.81, 95% CI 0.25 to 2.65, p = 0.73). The median time to fever clearance was 4.70 days (IQR 2.98–5.90) in the ofloxacin group versus 3.31 days (IQR 2.29–4.75) in the gatifloxacin group (HR = 1.59, 95% CI 1.16 to 2.18, p = 0.004). The results in all blood culture-confirmed patients and all randomized patients were comparable. Conclusion Gatifloxacin was not superior to ofloxacin in preventing failure, but use of gatifloxacin did result in more prompt fever clearance time compared to ofloxacin.

    Although the combination of cisplatin and gemcitabine (GEM) is considered the standard first-line chemotherapy against unresectable hilar cholangiocarcinoma (HC), its efficacy is discouraging. The present randomized open-label clinical trial aimed to evaluate the efficacy and safety of the GEM plus S-1 (GEM-S-1) combination against unresectable HC. Twenty-five patients per group were randomly assigned to receive GEM, S-1 or GEM-S-1. Neutropenia (56%) and leukopenia (40%) were the most common chemotherapy-related toxicities in the GEM-S-1 group. Median overall survival (OS) in the GEM-S-1, GEM and S-1 groups was 11, 10 and 6 months, respectively. GEM plus S-1 significantly improved OS compared to S-1 monotherapy (OR=0.68; 95%CI, 0.50–0.90; P=0.008). Median progression-free survival (PFS) times in the GEM-S-1, GEM and S-1 groups were 4.90, 3.70 and 1.60 months, respectively. GEM plus S-1 significantly improved PFS compared to S-1 monotherapy (OR=0.50; 95%CI, 0.27–0.91; P=0.024). Response rates were 36%, 24% and 8% in the GEM-S-1, GEM and S-1 groups, respectively. A statistically significant difference was found in response rates between the gemcitabine-S-1 and S-1 groups (36% vs 8%, P=0.017). Patients with CA19-9<466 U/ml were more responsive to chemotherapeutic agents than those with CA19-9≥571 U/ml (88.9% vs 0%, P<0.001). We conclude that the combination of GEM plus S-1 provides a better OS, PFS and response rate than S-1 monotherapy, but it did not significantly differ from GEM monotherapy. (ChiCTR-TRC-14004733).

    Negative symptoms of schizophrenia (NSS), related to hypodopaminergic activity in the mesocortical pathway and prefrontal cortex, are predictive of poor outcomes and have no effective treatment. Use of dopamine-enhancing drugs (eg, psychostimulants) has been limited by potential adverse effects. This multicenter study examined lisdexamfetamine dimesylate (LDX), a d-amphetamine prodrug, as adjunctive therapy to antipsychotics in adults with clinically stable schizophrenia and predominant NSS. Outpatients with stable schizophrenia, predominant NSS, limited positive symptoms, and maintained on stable atypical antipsychotic therapy underwent a 3-week screening, 10-week open-label adjunctive LDX (20–70 mg/day), and 4-week, double-blind, randomized, placebo-controlled withdrawal. Efficacy measures included a modified Scale for the Assessment of Negative Symptoms (SANS-18) and Positive and Negative Syndrome Scale (PANSS) total and subscale scores. Ninety-two participants received open-label LDX; 69 received double-blind therapy with placebo (n=35) or LDX (n=34). At week 10 (last observation carried forward; last open-label visit), mean (95% confidence interval) change in SANS-18 scores was −12.9 (−15.0, −10.8; P<0.0001). At week 10, 52.9% of participants demonstrated a minimum of 20% reduction from baseline in SANS-18 score. Open-label LDX was also associated with significant improvement in PANSS total and subscale scores. During the double-blind/randomized-withdrawal phase, no significant differences (change from randomization baseline) were found between placebo and LDX in SANS-18 or PANSS subscale scores. In adults with clinically stable schizophrenia, open-label LDX appeared to be associated with significant improvements in negative symptoms without positive symptom worsening. Abrupt LDX discontinuation was not associated with positive or negative symptom worsening. Confirmation with larger controlled trials is warranted. PMID:23756608

    The potential therapeutic utility of estrogens in schizophrenia is increasingly being recognized. Raloxifene, a selective estrogen receptor modulator, appears to act similarly to estrogens on dopamine and serotonin brain systems. One previous trial by our team found that raloxifene was useful to improve negative, positive, and general psychopathological symptoms, without having the negative side effects of estrogens. In this study, we assess the utility of raloxifene in treating negative and other psychotic symptoms in postmenopausal women with schizophrenia exhibiting prominent negative symptoms. This was a 24-week, randomized, parallel, double-blind, placebo-controlled study. Patients were recruited from the inpatient and outpatient departments of Parc Sanitari Sant Joan de Déu, Hospital Universitari Institut Pere Mata, and Corporació Sanitària Parc Taulí. Seventy postmenopausal women with schizophrenia (DSM-IV) were randomized to either adjunctive raloxifene (38 women) or adjunctive placebo (32 women). Psychopathological symptoms were assessed at baseline and at weeks 4, 12, and 24 with the Positive and Negative Syndrome Scale (PANSS) and the Scale for the Assessment of Negative Symptoms (SANS). The addition of raloxifene (60mg/d) to regular antipsychotic treatment significantly reduced negative (P = .027), general (P = .003), and total symptomatology (P = .005) measured with the PANSS during the 24-week trial, as compared to women receiving placebo. Also Alogia SANSS subscale improved more in the raloxifene (P = .048) than the placebo group. In conclusion, raloxifene improved negative and general psychopathological symptoms, compared with antipsychotic medication alone, in postmenopausal women with schizophrenia. These data replicate our previous results with a larger sample and a longer follow-up. Trial registration: NCT01573637. PMID:26591005

    Omadacycline is a first-in-class aminomethylcycline antibiotic with microbiological activity against Gram-positive and Gram-negative aerobes and anaerobes and atypical bacteria that is being developed for the treatment of acute bacterial skin and skin structure infections (ABSSSI) and community-acquired bacterial pneumonia (CABP). The bioavailability of a phase 3 tablet formulation relative to that obtained via intravenous (i.v.) administration (and of other oral formulations relative to that of the phase 3 tablet) was investigated in an open-label, randomized, four-period, crossover study with healthy subjects age 18 to 50 years. Subjects received omadacycline at 100 mg i.v., 300 mg orally as two different tablet formulations with different dissolution profiles, and 300 mg as an oral solution. Plasma omadacycline concentrations were determined using a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. Twenty of 24 subjects completed all treatment periods. The two tablet formulations produced equivalent total exposures. The phase 3 tablet produced an exposure equivalent to that of the 100-mg i.v. dose, with a geometric mean ratio (90% confidence intervals [CI]) for area under the concentration-time curve from 0 h to infinity [AUC∞]) of 1.00 (0.93, 1.07). The absolute bioavailability of the tablets was approximately 34.5%. Intersubject variability was consistent among the oral formulations (∼20 to 25%). Single oral and i.v. doses of omadacycline were well tolerated; three subjects experienced mild adverse events (dizziness, nausea, and vomiting) that resolved without intervention. A 300-mg dose of the tablet formulation of omadacycline intended for use in phase 3 studies produced a total exposure equivalent to that of a 100-mg i.v. dose. PMID:27736760

    Recent studies have suggested that long-term oxytocin administration can alleviate the symptoms of autism spectrum disorder (ASD); however, factors influencing its efficacy are still unclear. We conducted a single-center phase 2, pilot, randomized, double-blind, placebo-controlled, parallel-group, clinical trial in young adults with high-functioning ASD, to determine whether oxytocin dosage and genetic background of the oxytocin receptor affects oxytocin efficacy. This trial consisted of double-blind (12 weeks), open-label (12 weeks) and follow-up phases (8 weeks). To examine dose dependency, 60 participants were randomly assigned to high-dose (32 IU per day) or low-dose intranasal oxytocin (16 IU per day), or placebo groups during the double-blind phase. Next, we measured single-nucleotide polymorphisms (SNPs) in the oxytocin receptor gene (OXTR). In the intention-to-treat population, no outcomes were improved after oxytocin administration. However, in male participants, Clinical Global Impression-Improvement (CGI-I) scores in the high-dose group, but not the low-dose group, were significantly higher than in the placebo group. Furthermore, we examined whether oxytocin efficacy, reflected in the CGI-I scores, is influenced by estimated daily dosage and OXTR polymorphisms in male participants. We found that >21 IU per day oxytocin was more effective than ⩽21 IU per day, and that a SNP in OXTR (rs6791619) predicted CGI-I scores for ⩽21 IU per day oxytocin treatment. No severe adverse events occurred. These results suggest that efficacy of long-term oxytocin administration in young men with high-functioning ASD depends on the oxytocin dosage and genetic background of the oxytocin receptor, which contributes to the effectiveness of oxytocin treatment of ASD.

    Background We investigated whether sirolimus-based immunosuppression improves outcomes in liver transplantation (LTx) candidates with hepatocellular carcinoma (HCC). Methods In a prospective-randomized open-label international trial, 525 LTx recipients with HCC initially receiving mammalian target of rapamycin inhibitor–free immunosuppression were randomized 4 to 6 weeks after transplantation into a group on mammalian target of rapamycin inhibitor–free immunosuppression (group A: 264 patients) or a group incorporating sirolimus (group B: 261). The primary endpoint was recurrence-free survival (RFS); intention-to-treat (ITT) analysis was conducted after 8 years. Overall survival (OS) was a secondary endpoint. Results Recurrence-free survival was 64.5% in group A and 70.2% in group B at study end, this difference was not significant (P = 0.28; hazard ratio [HR], 0.84; 95% confidence interval [95% CI], 0.62; 1.15). In a planned analysis of RFS rates at yearly intervals, group B showed better outcomes 3 years after transplantation (HR, 0.7; 95% CI, 0.48-1.00). Similarly, OS (P = 0.21; HR, 0.81; 95% CI, 0.58-1.13) was not statistically better in group B at study end, but yearly analyses showed improvement out to 5 years (HR, 0.7; 95% CI, 0.49-1.00). Interestingly, subgroup (Milan Criteria-based) analyses revealed that low-risk, rather than high-risk, patients benefited most from sirolimus; furthermore, younger recipients (age ≤60) also benefited, as well sirolimus monotherapy patients. Serious adverse event numbers were alike in groups A (860) and B (874). Conclusions Sirolimus in LTx recipients with HCC does not improve long-term RFS beyond 5 years. However, a RFS and OS benefit is evident in the first 3 to 5 years, especially in low-risk patients. This trial provides the first high-level evidence base for selecting immunosuppression in LTx recipients with HCC. PMID:26555945

    Severe organophosphate compound (OPC) poisoning is an important clinical problem in many countries of the world. Unfortunately, little clinical research has been performed and little evidence exists with which to determine the best therapy. A study was therefore undertaken to determine the optimal dosing regimen for atropine in the treatment of OPC poisoning. An open-label randomized clinical trial was conducted in Chittagong Medical College Hospital, Chittagong, Bangladesh, on 156 hospitalized individuals with OPC poisoning from June to September 2006. The aim was to compare the efficacy and safety of conventional bolus doses with individualized incremental doses of atropine for atropinization followed by continuous atropine infusion for management of OPC poisoning. Inclusion criteria were patients with a clear history of OPC poisoning with clear clinical signs of toxicity, i.e. features of cholinergic crisis. The patients were observed for at least 96 h. Immediate outcome and complications were recorded. Out of 156 patients, 81 patients received conventional bolus dose atropine (group A) and 75 patients received rapidly incremental doses of atropine followed by infusion (group B). The mortality in group 'A' was 22.5% (18/80) and in group 'B' 8% (6/75) (p < 0.05). The mean duration of atropinization in group 'A' was 151.74 min compared to 23.90 min for group 'B' (p < 0.001). More patients in group A experienced atropine toxicity than in group 'B' (28.4% versus 12.0%, p < 0.05); intermediate syndrome was more common in group 'A' than in group 'B' (13.6% versus 4%, p < 0.05), and respiratory support was required more often for patients in group 'A' than in group 'B' (24.7% versus 8%, p < 0.05). Rapid incremental dose atropinization followed by atropine infusion reduces mortality and morbidity from OPC poisoning and shortens the length of hospital stay and recovery. Incremental atropine and infusion should become the treatment of choice for OPC

    We tested the feasibility of setting individualized glycemic goals and factors influencing targets set in a clinical trial in elderly patients with type 2 diabetes.A 24-week, randomized, double-blind, placebo-controlled study was conducted in 45 outpatient centers in seven European countries. 278 drug-naïve or inadequately controlled (mean HbA1c 7.9%) patients with type 2 diabetes aged ≥70 years with HbA1c levels ≥7.0% and ≤10.0% were enrolled. Investigator-defined individualized HbA1c targets and the impact of baseline characteristics on individualized treatment targets was evaluated.The average individualized HbA1c target was set at 7.0%. HbA1c at baseline predicted a target setting such that higher the HbA1c, more aggressive was the target (P<0.001). Men were more likely to be set aggressive targets than women (P=0.026). Frailty status of patients showed a trend towards significance (P=0.068), whereas diabetes duration, age, or polypharmacy did not. There was heterogeneity between countries regarding how baseline factors were viewed.Despite training and guidance to individualize HbA1c goals, targets were still set in line with conventional values. A strong influence of country-specific guidelines on target setting was observed; confirming the importance of further education to implement new international guidelines in older adults.

    Aim To test the efficacy and safety of osmotic release oral system (OROS) methylphenidate (MPH) in doses up to 180 mg/day to treat attention deficit hyperactivity disorder (ADHD) and prevent any drug relapse in individuals with a co-diagnosis of ADHD and amphetamine dependence. Design Randomized placebo-controlled 24-week double-blind trial with parallel groups design. Setting Participants were recruited from medium security prisons in Sweden. The medication started within 2 weeks before release from prison and continued in out-patient care with twice-weekly visits, including once-weekly cognitive behavioural therapy. Participants Fifty-four men with a mean age of 42 years, currently incarcerated, meeting DSM-IV criteria for ADHD and amphetamine dependence. Measurements Change in self-reported ADHD symptoms, relapse to any drug use (amphetamine and other drugs) measured by urine toxicology, retention to treatment, craving and time to relapse. Findings The MPH-treated group reduced their ADHD symptoms during the trial (P = 0.011) and had a significantly higher proportion of drug-negative urines compared with the placebo group (P = 0.047), including more amphetamine-negative urines (P = 0.019) and better retention to treatment (P = 0.032). Conclusions Methylphenidate treatment reduces attention deficit hyperactivity disorder symptoms and the risk for relapse to substance use in criminal offenders with attention deficit hyperactivity disorder and substance dependence.

    The purposes of this study were to analyze the impact of 24 weeks of vibratory and multicomponent training (MT) and to determine what type of training creates greater adaptations on body composition and isokinetic strength of the knee and ankle joints in postmenopausal women. Thirty-eight women (60.0 ± 6.3 years) were randomly assigned to whole body vibration group (WBVG), multicomponent training group (MTG), or a control group. A significant decrease in total fat mass was observed in experimental groups. There were no changes in total lean mass and total bone mineral density in both groups. WBVG and MTG showed significant increases in isokinetic strength for knee extensors at 60°/s and at 270°/s. Regarding the ankle joint, there were significant increments in strength for plantar flexion at 60°/s in WBVG and at 120°/s in the two trainings groups. MTG showed a significant increase in strength for dorsiflexion at 60°/s. With respect to eversion and inversion, WBVG and MTG improved strength at 60°/s. Also, the WBVG showed increased strength in the ankle evertors at 120°/s and both groups showed increased strength in the ankle invertors at 120°/s. Twenty-four weeks of whole body vibration or MTs result in positive modifications in total fat mass. These trainings are effective in improving knee extension and stabilizer muscles of the ankle joint strength.

    Background: A series of studies has suggested some efficacy of glucosamine in arthrosis of the knee, but virtually no documentation exists regarding its effects on low back pain. Objectives: The primary objective of this study was to examine whether a 12-week course of a glucosamine complex (GC) could benefit patients having low back pain despite a course of noninvasive physical therapy. In addition, we sought to delineate the subgroup of responders. Methods: This open-label, randomized, controlled study was conducted at the Division of Rheumatology and Physical Medicine, Erasme University Hospital, Brussels, Belgium. Male and female outpatients aged 40 to 80 years with low back pain (duration, ≥ 12 weeks; pain score on 10-cm visual analog scale [VAS] [0 = none to 10 = worst imaginable], ≥3 cm) despite noninvasive physical therapy (massage, stretching, heat application, and analgesics for ≥4 weeks) were included. Patients were randomly assigned to receive, in addition to conventional treatment (CT) (physical therapy plus analgesics/antiinflammatories), a GC (enriched with sulfonyl methane, silicon, and a botanical extract of Ribes nigrum) or CT alone (control) for 12 weeks. Pain at rest and on movement (effort) and early morning lumbar stiffness were measured every 4 weeks using the VAS. The primary end point was improvement in VAS score for pain at rest at 12 weeks. Two validated questionnaires were used to assess improvements in quality of life (QOL) (Oswestry Disability Questionnaire [ODQ] [10 items; scale: 0 = no disability to 60 = maximal disability] and Roland-Morris Disability Questionnaire [RMDQ] [24 items; scale: 0 = no disability to 24 = severe disability]). Responders were defined as patients who positively assessed the efficacy of the GC. At each visit, patients were also asked about possible adverse events. Results: Of 36 enrolled patients, 32 completed the study (18 men, 14 women; mean [SE] age, 64 [2] years; 17 in the GC group and 15 in the

    Background Inhaled glucocorticosteroids (ICS) are the mainstay of treatment in asthma. Fluticasone furoate (FF) is a novel, once-daily ICS asthma therapy. This study investigated the efficacy and safety of FF 50 mcg in patients with mild-to-moderate persistent asthma. Methods A 24-week, multicenter, randomized, placebo-controlled and active-controlled, double-blind, double-dummy, parallel-group phase III study. Three hundred and fifty-one patients (aged ≥12 years; uncontrolled by non-ICS therapy) were randomized to treatment (1 : 1 : 1) with once-daily FF 50 mcg dosed in the evening, twice-daily fluticasone propionate (FP) 100 mcg or placebo. The primary endpoint was change from baseline in evening trough forced expiratory volume in 1 s (FEV1) at Week 24. Secondary endpoints were change from baseline in the percentage of rescue-free 24-h periods (powered endpoint), change from baseline in evening and morning peak expiratory flow, change from baseline in the percentage of symptom-free 24-h periods and number of withdrawals due to lack of efficacy. Results Evening trough FEV1 at Week 24 was not statistically significantly increased with FF 50 mcg once-daily (37 ml [95% CI: −55, 128]; P = 0.430), but was with FP 100 mcg twice daily (102 ml [10, 194]; P = 0.030), vs placebo. No consistent trends were observed across other endpoints, including the powered secondary endpoint. No safety concerns were raised for either active treatment. Conclusions FP 100 mcg twice daily improved evening trough FEV1 in patients with mild-to-moderate persistent asthma, but FF 50 mcg once daily did not demonstrate a significant effect. Secondary endpoints showed variable results. No safety concerns were identified for FF or FP. PMID:25040613

    Current treatment options for MPS I have limited effects on some organs, including the skeletal system. In MPS animal models pentosan polysulphate (PPS) reduces the concentrations of glycosaminoglycans (GAGs) in tissues and body fluids and improves cartilaginous and osseous pathologies. The goals of this study were to investigate primarily the safety and secondary the clinical effects, concerning mobility and pain, of PPS treatment in MPS I patients. Four MPS I-Hurler-Scheie/-Scheie patients aged 35.6 ± 6.4 years with one male were included in the study. All patients were on enzyme replacement therapy since 9.45 ± 3.75 years. PPS was applied subcutaneously in two patients with 1 mg/kg and in two patients with 2 mg/kg, weekly for 12 weeks and then biweekly for 12 weeks. The 24-week treatment with PPS was well tolerated by all patients. Urinary GAG concentrations were reduced from 4.13 ± 1.17 at baseline to 2.69 ± 0.36 mg/mmol creatinine after 24-week treatment with 1 mg/kg PPS, and from 6.71 ± 0.62 to 2.65 ± 0.09 mg/mmol creatinine with 2 mg/kg PPS. An improvement in range of motion was noted in three out of four patients. The pain intensity score was reduced from 4.5 ± 1.77 at baseline to 1.8 ± 0.47 after 24-week treatment with 1 mg/kg PPS; patients with 2 mg/kg PPS already had minimal pain at the start of the study. In conclusion, PPS treatment in a small number of adult MPS I patients was well tolerated and resulted in a significant reduction of urinary GAG excretion and in an improvement of joint mobility and pain.

    Somatic symptoms are often important in the treatment of major depressive disorder (MDD). The aim of this open-labeled trial was to examine the efficacy of mirtazapine for the treatment of MDD with clinically significant somatic symptoms, as compared with venlafaxine. A total of 126 patients with MDD (score >/=18 on the Hamilton Rating Scale for Depression-17) were included in both the intent-to-treat (n=73 in the mirtazapine group and n=53 in the venlafaxine group) and completer analysis (n=51 and n=37, respectively). After treatment, both treatment groups showed similar improvements in depressive symptoms. Repeated measures analysis of variance for the intent-to-treat population revealed that there were no significant differences in mean change of the Symptom Check List-90-Revised (SCL-90-R) somatization subscores between the two groups. For completers, there was a significant timextreatment interaction in the SCL-90-R somatization subscores, but the differences between the two groups at endpoint did not reach statistical significance in post-hoc analysis. In conclusion, this study suggests that overall efficacies of mirtazapine and venlafaxine are similar for the treatment of overall symptoms in MDD, and both drugs may be useful for the treatment of somatic symptoms in MDD patients.

    Sacroiliac joint (SIJ) pain is a common symptom in ankylosing spondylitis (AS). Palisade sacroiliac joint radiofrequency neurotomy (PSRN) is a novel treatment for the SIJ pain. In the current clinical trial, we treated AS patients with significant SIJ pain using PSRN under computed tomography guidance and compared the results with the celecoxib treatment. The current study included 155 AS patients. Patients were randomly assigned to receive PSRN or celecoxib treatment (400 mg/day for 24 weeks). The primary endpoint was global pain intensity in visual analog scale, at week 12. Secondary endpoints included pain intensity at week 24, disease activity, functional and mobility capacities, and adverse events at week 24. In comparison with the baseline collected immediately prior to the interventions, global pain intensity was significantly lower at both 12 and 24 weeks after the treatment in both arms. Pain reduction was more robust in the PSRN arm (by more than 1.9 and 2.2 cm at 12 and 24 weeks in comparison with the celecoxib arm, P < 0.0001 for both). The PSRN was also more effective in improving physical function and spinal mobility (P < 0.05 vs. celecoxib for both). Gastrointestional irritation was more frequent in the celecoxib arm than in the PSRN arm (P < 0.05). No severe complications were noted in either arm. PSRN is both efficacious and safe in managing SIJ pain in patients with AS.

    Purpose The efficacy and safety of denosumab was compared with placebo in Korean postmenopausal women with osteoporosis in this phase III study. Materials and Methods Women aged 60 to 90 years with a T-score of <-2.5 and ≥-4.0 at the lumbar spine or total hip were randomized to a single 60 mg subcutaneous dose of denosumab or placebo for the 6-month double-blind phase. Eligible subjects entered the 6-month open-label extension phase and received a single dose of denosumab 60 mg. Results Baseline demographics were similar in the 62 denosumab- and 64 placebo-treated subjects who completed the double-blind phase. Treatment favored denosumab over placebo for the primary endpoint {mean percent change from baseline in lumbar spine bone mineral density (BMD) at Month 6 [3.2% (95% confidence interval 2.1%, 4.4%; p<0.0001)]}; and secondary endpoints (mean percent change from baseline in lumbar spine BMD at Month 1, total hip, femoral neck, and trochanter BMD at Months 1 and 6, and median percent change from baseline in bone turnover markers at Months 1, 3, and 6). Endpoint improvements were sustained over 12 months in the open-label extension (n=119). There were no new or unexpected safety signals. Conclusion Denosumab was well tolerated and effective in increasing BMD and decreasing bone turnover markers over a 12-month period in Korean postmenopausal women. The findings of this study demonstrate that denosumab has beneficial effects on the measures of osteoporosis in Korean postmenopausal women. PMID:27189284

    In recent years a series of trials has sought to define the optimal protocol for everolimus-based immunosuppression in heart transplantation, with the goal of minimizing exposure to calcineurin inhibitors (CNIs) and harnessing the non-immunosuppressive benefits of everolimus. Randomized studies have demonstrated that immunosuppressive potency can be maintained in heart transplant patients receiving everolimus despite marked CNI reduction, although very early CNI withdrawal may be inadvisable. A potential renal advantage has been shown for everolimus, but the optimal time for conversion and the adequate reduction in CNI exposure remain to be defined. Other reasons for use of everolimus include a substantial reduction in the risk of cytomegalovirus infection, and evidence for inhibition of cardiac allograft vasculopathy, a major cause of graft loss. The ongoing MANDELA study is a 12-month multicenter, randomized, open-label, parallel-group study in which efficacy, renal function and safety are compared in approximately 200 heart transplant patients. Patients receive CNI therapy, steroids and everolimus or mycophenolic acid during months 3 to 6 post-transplant, and are then randomized at month 6 post-transplant (i) to convert to CNI-free immunosuppression with everolimus and mycophenolic acid or (ii) to continue reduced-exposure CNI, with concomitant everolimus. Patients are then followed to month 18 post-transplant The rationale and expectations for the trial and its methodology are described herein.

    We aimed to compare effectiveness of Wenxin Keli (WK) and sotalol in assisting sinus rhythm (SR) restoration from paroxysmal atrial fibrillation (PAF) caused by hyperthyroidism, as well as in maintaining SR. We randomly prescribed WK (18 g tid) or sotalol (80 mg bid) to 91 or 89 patients. Since it was not ethical not to give patients antiarrhythmia drugs, no control group was set. Antithyroid drugs were given to 90 patients (45 in WK group, 45 in sotalol group); 131I was given to 90 patients (46 in WK group, 44 in sotalol group). Three months later, SR was obtained in 83/91 or 80/89 cases from WK or sotalol groups (P = 0.762). By another analysis, SR was obtained in 86/90 or 77/90 cases from 131I or ATD groups (P = 0.022). Then, we randomly assigned the successfully SR-reverted patients into three groups: WK, sotalol, and control (no antiarrhythmia drug was given) groups. After twelve-month follow-up, PAF recurrence happened in 1/54, 2/54, and 9/55 cases, respectively. Log-Rank test showed significant higher PAF recurrent rate in control patients than either treatment (P = 0.06). We demonstrated the same efficacies of WK and sotalol to assist SR reversion from hyperthyroidism-caused PAF. We also showed that either drug could maintain SR in such patients. PMID:26074982

    Activation of heat shock response (HSR) improves accumulated visceral adiposity and metabolic abnormalities in type 2 diabetes. To identify the optimal intervention strategy of the activation of the HSR provided by mild electrical stimulation (MES) with heat shock (HS) in type 2 diabetes. This study was a prospective, frequency-escalating, randomized, open-label, triple-arm trial in Japan. A total of 60 obese type 2 diabetes patients were randomized into three groups receiving two, four, or seven treatments per week for 12 weeks. No adverse events were identified. MES + HS treatment (when all three groups were combined), significantly improved visceral adiposity, glycemic control, insulin resistance, systemic inflammation, renal function, hepatic steatosis and lipid profile compared to baseline. The reduction in HbA1c was significantly greater among those treated four times per week (−0.36%) or seven times per week (−0.65%) than among those treated two times per week (−0.10%). The relative HbA1c levels in seven times per week group was significantly decreased when adjusted by two times per week group (−0.55%. p = 0.001). This research provides the positive impact of MES + HS to treat obese patients with type 2 diabetes mellitus. PMID:27759092

    Background. Treatment of hyperlipidemia is helpful in both primary and secondary prevention of coronary heart disease and stroke. Aim. To compare lipid-lowering efficacy of rosuvastatin with atorvastatin. Methodology. This open-label randomized controlled trial was carried out at 1 Mountain Medical Battalion from September 2012 to August 2013 on patients with type 2 diabetes, hypertension, myocardial infarction, or stroke, meriting treatment with a statin. Those with secondary causes of dyslipidemia were excluded. Blood samples for estimation of serum total cholesterol, triglycerides, HDL-C, and LDL-C were collected after a 12-hour fast. Patients were randomly allocated to receive either atorvastatin 10 mg HS or rosuvastatin 5 mg HS daily. Lipid levels were rechecked after six weeks. Results. Atorvastatin was used in 63 patients and rosuvastatin in 66. There was a greater absolute and percent reduction in serum LDL-C levels with rosuvastatin as compared to atorvastatin (0.96 versus 0.54 mg/dL; P = 0.011 and 24.34 versus 13.66%; P = 0.045), whereas reduction in all other fractions was equal. Myalgias were seen in 5 (7.94%) patients treated with atorvastatin and 8 (12.12%) patients treated with rosuvastatin (P: 0.432). Conclusion. Rosuvastatin produces a greater reduction in serum LDL-C levels and should therefore be preferred over atorvastatin. PMID:24800084

    To compare the effect of IV immune globulin (IVIG) and anti-D globulin (anti-D) for treatment of immune thrombocytopenia (ITP) in children. A randomized, open-label, single-center clinical trial was carried out in Amir-Kabir Hospital (Arak, Iran). The study was performed on 60 children with acute and chronic ITP, aged from 1 to 15 years. Patients were randomly assigned (1:1) to 50 μg/kg anti-D or 1 g/kg IVIG. Platelet counting was performed at baseline and at 3, 7, and 14 days after treatment termination. Safety assessment was performed in all patients. Anti-D caused a quicker response on the 3rd day of treatment (P < 0.001). Both drugs caused a significant rise in number of platelets on the 7th and the 14th day of treatment. Compared to IVIG, except a significant drop in hemoglobin concentration (P < 0.001), anti-D had lower rate of side effects including fever (P < 0.05), allergy (P < 0.01), and headache (P < 0.001). Our results showed that anti-D was associated with rapid rise of platelets compared to IVIG. In addition, anti-D treatment had acceptable safety profile.

    Despite the availability of efficacious treatments, only half of patients with hypertension achieve adequate blood pressure (BP) control. This paper describes the protocol and baseline subject characteristics of a 2-arm, 18-month randomized clinical trial of titrated disease management (TDM) for patients with pharmaceutically-treated hypertension for whom systolic blood pressure (SBP) is not controlled (≥140mmHg for non-diabetic or ≥130mmHg for diabetic patients). The trial is being conducted among patients of four clinic locations associated with a Veterans Affairs Medical Center. An intervention arm has a TDM strategy in which patients' hypertension control at baseline, 6, and 12months determines the resource intensity of disease management. Intensity levels include: a low-intensity strategy utilizing a licensed practical nurse to provide bi-monthly, non-tailored behavioral support calls to patients whose SBP comes under control; medium-intensity strategy utilizing a registered nurse to provide monthly tailored behavioral support telephone calls plus home BP monitoring; and high-intensity strategy utilizing a pharmacist to provide monthly tailored behavioral support telephone calls, home BP monitoring, and pharmacist-directed medication management. Control arm patients receive the low-intensity strategy regardless of BP control. The primary outcome is SBP. There are 385 randomized (192 intervention; 193 control) veterans that are predominately older (mean age 63.5years) men (92.5%). 61.8% are African American, and the mean baseline SBP for all subjects is 143.6mmHg. This trial will determine if a disease management program that is titrated by matching the intensity of resources to patients' BP control leads to superior outcomes compared to a low-intensity management strategy.

    Effective noninvasive interventions for insomnia are needed. High-resolution, relational, resonance-based, electroencephalic mirroring (HIRREM™) is a noninvasive, electroencephalography (EEG)-based method to facilitate greater client-unique, autocalibrated improvements of balance and harmony in cortical neural oscillations. This study explores using HIRREM for insomnia. Twenty subjects, with an Insomnia Severity Index (ISI) score of ≥15 (14 women, mean age 45.4, mean ISI 18.6), were enrolled in this randomized, unblinded, wait-list control, crossover, superiority study. Subjects were randomized to receive 8–12 HIRREM sessions over 3 weeks, plus usual care (HUC), or usual care alone (UC). Pre- and post-HIRREM data collection included ISI (primary outcome), and many secondary, exploratory measures (CES-D, SF-36, HR, BP, neurocognitive testing, and VAS scales). The UC group later crossed over to receive HIRREM. ISI was also repeated 4–6 weeks post-HIRREM. All subjects completed the primary intervention period. Analysis for differential change of ISI in the initial intervention period for HUC versus UC showed a drop of 10.3 points (95% CI: −13.7 to −6.9, P < 0.0001, standardized effect size of 2.68). Key secondary outcomes included statistically identical differential change for the crossed-over UC group, and persistence of the effect on the ISI up to > 4 weeks post-HIRREM. Differential change in the HUC group was also statistically significant for CES-D (−8.8, 95% CI: −17.5 to −0.1, P = 0.047), but other exploratory outcomes were not statistically significant. For all receiving HIRREM (n = 19), decreased high-frequency total power was seen in the bilateral temporal lobes. No adverse events were seen. This pilot clinical trial, the first using HIRREM as an intervention, suggests that HIRREM is feasible and effective for individuals having moderate-to-severe insomnia, with clinically relevant, statistically significant benefits based on differential

    Extrapyramidal symptoms (EPS) are common adverse effects of antipsychotic treatment. This study examined the effects of the traditional Japanese herbal medicine (kampo) shakuyaku-kanzo-to on EPS during antipsychotic treatment. Twenty-two Japanese patients with psychiatric disorders who had developed EPS during antipsychotic treatment were randomly allocated to receive either shakuyaku-kanzo-to (7.5 g/d) or biperiden (3 mg/d) for 2 weeks. Extrapyramidal symptoms were evaluated using the Drug-Induced Extrapyramidal Symptom Scale (DIEPSS) and the Barnes Akathisia Rating Scale. Plasma levels of the monoamine metabolite homovanillic acid and serum prolactin levels were measured to investigate the mechanisms of action of shakuyaku-kanzo-to. Twenty of the 22 patients completed the study (10 patients in the shakuyaku-kanzo-to group and 10 patients in the biperiden group). There was a time effect on the Drug-Induced Extrapyramidal Symptom Scale total score (P < 0.01), suggesting that both shakuyaku-kanzo-to and biperiden decreased EPS. Notably, there was a time × drug interaction in dystonia, suggesting that shakuyaku-kanzo-to had a greater effect on dystonia compared with biperiden. No significant changes were observed in plasma homovanillic acid or serum prolactin levels after 2 weeks of treatment in either group. The effects of shakuyaku-kanzo-to on abnormal muscle tonus and dopamine D2 receptors may have contributed to improve EPS. These results suggest that shakuyaku-kanzo-to may be useful in decreasing EPS, especially dystonia, in patients undergoing treatment with antipsychotic agents.

    Aims. To assess the effect of metformin and to compare it with insulin treatment in patients with type 2 diabetes in pregnancy in terms of perinatal outcome, maternal complications, additional insulin requirement, and treatment acceptability. Methods. In this randomized, open label study, 206 patients with type 2 diabetes in pregnancy who met the eligibility criteria were selected from the antenatal clinics. Insulin was added to metformin treatment when required, to maintain the target glycemic control. The patients were followed up till delivery. Maternal, and perinatal outcomes and pharmacotherapeutic characteristics were recorded on a proforma. Results. Maternal characteristics were comparable in metformin and insulin treated group. 84.9% patients in metformin group required add-on insulin therapy at mean gestational age of 26.58 ± 3.85 weeks. Less maternal weight gain (P < 0.001) and pregnancy induced hypertension (P = 0.029) were observed in metformin treated group. Small for date babies were more in metformin group (P < 0.01). Neonatal hypoglycemia was significantly less and so was NICU stay of >24 hours in metformin group (P < 0.01). Significant reduction in cost of treatment was found in metformin group. Conclusion. Metformin alone or with add-on insulin is an effective and cheap treatment option for patients with type 2 diabetes in pregnancy.

    Antiemetic treatment compliance is important to prevent chemotherapy-induced nausea and vomiting, a feared chemotherapy side effect. NEPA, a new oral fixed combination of netupitant, a highly selective NK1 receptor antagonist (RA), and palonosetron, a second-generation 5-HT3 RA, targets dual antiemetic pathways with a single dose. This study investigated the effect of food intake and age on NEPA pharmacokinetics (PK) and safety. In this open-label, single-center, randomized, phase 1 study, 24 adults (18-45 years) received NEPA in a fed or fasted state during the first treatment period and in the alternative state in the next treatment period. Twelve elderly subjects (≥65 years) received NEPA in a fasted state. Blood samples were taken for netupitant and palonosetron PK analysis. In the fed condition, netupitant plasma exposure increased, whereas palonosetron PK parameters were not affected. Furthermore, elderly subjects showed increased netupitant and palonosetron exposure compared with adults. All adverse events were mild/moderate, with constipation and headache the most common. Although food intake and age altered NEPA PK, dose adjustments were not needed, as netupitant and palonosetron exposure increases did not lead to safety concerns in healthy subjects.

    The purpose of this trial is to evaluate the clinical efficacy and cost/effectiveness of Saccharomyces boulardii compared with yogurt fluid (YF) in acute non-bloody diarrhea in children. This randomized, prospective open-label clinical trial includes 55 children (36 boys, 19 girls; mean age 21.2 +/- 28.2 months). Group A (N = 28) received lyophilized S. boulardii and group B (N = 27) received YF. The duration of diarrhea was shorter with S. boulardii but the hospital stay was reduced with YF, although these differences were not significant. However, diarrhea had resolved in significantly more children on day 3 in the S. boulardii group (48.5% versus 25.5%; P < 0.05). In outpatient cases, yogurt treatment was cheaper than S. boulardii whereas in hospitalized patients, treatment cost was similar. In conclusion, the effect of daily freshly prepared YF was comparable to S. boulardii in the treatment of acute non-bloody diarrhea in children. The duration of diarrhea was shorter in the S. boulardii group, expressed as a significantly higher number of patients with normal stools on day 3.

    Worldwide, paracetamol is administered as a remedy for complaints that occur after vaccination. Recently published results indicate that paracetamol inhibits the vaccination response in infants when given prior to vaccination. The goal of this study was to establish whether paracetamol exerts similar effects in young adults. In addition, the effect of timing of paracetamol intake was investigated. In two randomized, controlled, open-label studies 496 healthy young adults were randomly assigned to three groups. The study groups received paracetamol for 24 hours starting at the time of (prophylactic use) - or 6 hours after (therapeutic use) the primary (0 month) and first booster (1 month) hepatitis B vaccination. The control group received no paracetamol. None of the participants used paracetamol around the second booster (6 months) vaccination. Anti-HBs levels were measured prior to and one month after the second booster vaccination on ADVIA Centaur XP. One month after the second booster vaccination, the anti-HBs level in the prophylactic paracetamol group was significantly lower (p = 0.048) than the level in the control group (4257 mIU/mL vs. 5768 mIU/mL). The anti-HBs level in the therapeutic paracetamol group (4958 mIU/mL) was not different (p = 0.34) from the level in the control group. Only prophylactic paracetamol treatment, and not therapeutic treatment, during vaccination has a negative influence on the antibody concentration after hepatitis B vaccination in adults. These findings prompt to consider therapeutic instead of prophylactic treatment to ensure maximal vaccination efficacy and retain the possibility to treat pain and fever after vaccination.

    Background & objectives: Improving quality of life (QOL) of healthy people living with HIV (PLHIV) is critical needing home-based, long-term strategy. Sudarshan Kriya yoga (SKY) intervention is acknowledged for its positive impact on health. It is hypothesised that SKY would improve PLHIV's QOL, justifying an evaluation. Methods: In this open label randomized controlled pilot trial, 61 adult PLHIV with CD4 count more than 400 cells/µl and Karnofsky scale score above 70 were enrolled. Those with cardiac disease, jaundice, tuberculosis, or on antiretroviral therapy/yoga intervention were excluded. All were given standard care, randomized to SKY intervention (31: I-SKY) and only standard of care in control (30: O-SOC) arms. The I-SKY participants were trained for six days to prepare for daily practice of SKY at home for 30 min. A validated 31-item WHOQOL-HIVBREF questionnaire was used to document effect in both arms from baseline to three visits at 4 wk interval. Results: Baseline QOL scores, hypertension and CD4 count were similar in both arms. An overall 6 per cent improvement of QOL scores was observed in I-SKY group as compared to O-SOC group, after controlling for baseline variables like age, gender, education and occupation (P =0.016); 12 per cent for physical (P =0.004), 11 per cent psychological (P =0.023) and 9 per cent level of independence (P =0.001) domains. Improvement in I-SKY observed at post-training and in the SKY adherence group showed increase in these two domains. Conclusions: A significant improvement in QOL scores was observed for the three health related QOL domains in SKY intervention arm. This low cost strategy improved physical and psychological state of PLHIV calling for upscaling with effective monitoring for sustainability of quality of life. PMID:25857500

    Initiation of ED treatment with a particular PDE5I may influence treatment-adherence and other outcomes. In this multicenter, open-label study, men with ED, naïve to PDE5I, were randomized to tadalafil 5 mg once-a-day (OaD; N=257), 10 mg on demand (PRN; N = 252) or sildenafil-citrate (sildenafil) 50 mg PRN (N = 261) for 8 weeks (dose adjustments allowed), followed by 16 weeks of pragmatic treatment (switching between PDE5I allowed). Primary outcomes (treatment-adherence) were reported previously. Here, we report effects on: Psychological and Interpersonal Relationship Scales, Self-Esteem and Relationship (SEAR) questionnaire, ED Inventory of Treatment Satisfaction (EDITS), International Index of Erectile Function (IIEF), Sexual Encounter Profile (SEP) and Global Assessment Questions (GAQ). Mixed-model for repeated measures and analysis of covariance were used to analyze changes from baseline; GAQ-responses were evaluated by logistic regression. Analyses were adjusted for treatment, country, ED-severity, baseline and baseline-by-treatment interaction. Patients randomized to tadalafil OaD or PRN reported greater improvement (least-square mean (s.e.) change) in Sexual Self-Confidence (OaD +0.90 (0.048), PRN +0.93 (0.050), vs +0.73 (0.049); P=0.006 and P=0.001) and Spontaneity (OaD +0.11 (0.035), PRN +0.13 (0.035), vs +0.02 (0.035); P = 0.044 and P = 0.010) compared with sildenafil. Improvements in GAQ and SEP responses, IIEF-EF, orgasmic function, sexual desire, overall satisfaction domains, SEAR and EDITS scores did not differ significantly between treatment groups.

    Background Community health workers (CHW) are increasingly recognized as a strategy to improve health outcomes for the underserved with chronic diseases but has not been formally explored in adolescents with sickle cell disease (SCD). SCD primarily affects African American, Hispanic and other traditionally underserved populations. Hydroxyurea (HU), an oral, once-daily medication, is the only approved therapeutic drug for sickle cell disease and markedly reduces symptoms, morbidity and mortality and improves quality of life largely by increasing hemoglobin F blood levels. This paper presents the rationale, study design and protocol for an open label randomized controlled trial to improve parent-youth partnerships in self-management and medication adherence to HU in adolescents with SCD. Methods/Design A CHW intervention augmented by text messaging was designed for adolescents with SCD ages 10–18 years and their parents to improve daily HU adherence. Thirty adolescent parent dyads will be randomized with 2:1 intervention group allocation. Intervention dyads will establish a relationship with a culturally aligned CHW to identify barriers to HU use, identify cues to build a habit, and develop a dyad partnership to improve daily HU adherence and achieve their individualized “personal best” hemoglobin F target. Intervention feasibility, acceptability and efficacy will be assessed via a 2-site trial. Outcomes of interest are HU adherence, dyad self-management communication, quality of life, and resource use. Discussion Despite known benefits, poor HU adherence is common. If feasible and acceptable, the proposed intervention may improve health of underserved adolescents with SCD by enhancing long-term HU adherence. PMID:27327779

    A chemotherapy regimen of docetaxel, doxorubicin and cyclophosphamide (TAC) has been accepted as a standard care because of their superior clinical benefit in early-stage breast cancer patients, but with a higher risk of neutropenia. Pegfilgrastim is a once-per-cycle therapy for prophylactic neutrophil support and neutropenia prevention. There was still a lack of direct evidences for finding an optimal fixed dose of pegfilgrastim in Chinese breast cancer patients receiving TAC regimen. An open-label, randomized, phase II study was designed to compare the effects of pegfilgrastim with filgrastim. Eighteen centers in China enrolled 171 eligible female breast cancer patients with cycles of TAC chemotherapy treatment, randomized into four arms, received a single subcutaneous injection of pegfilgrastim (60, 100 or 120 µg/kg) per chemotherapy cycle or daily subcutaneous injections of filgrastim 5 µg/kg 24 h after chemotherapy. Efficacy and safety were analyzed. In ITT population, the mean duration of grade 3+ neutropenia (neutrophil count <1.0 × 10(9)/l) was 2.09, 1.53 and 1.73 days in patients who received pegfilgrastim 60, 100 and 120 µg/kg/cycle, respectively, and 1.69 days in patients who received 5 µg/kg/day filgrastim (P = 0.043). The incidence of grade 3+ neutropenia was 76, 83 and 74 % for doses of pegfilgrastim and 90 % for filgrastim (P = 0.409). The results for febrile neutropenia, time to neutrophil recovery and neutrophil profile were also not significantly different between arms. The safety profiles of pegfilgrastim and filgrastim were similar. A single dose of 100 µg/kg once-per-cycle administration of pegfilgrastim provided neutrophil support and a safety profile comparable to daily subcutaneous injections of filgrastim in Chinese breast cancer patients receiving TAC chemotherapy.

    Background Oral candidiasis (OC) is a common oral fungal infection. Recently, miconazole mucoadhesive tablets have been gaining attention for OC treatment. Despite trials in patients with human immunodeficiency virus and cancer, evidence of its application in the large-scale, general population with OC is lacking. This study aimed to evaluate the efficacy and safety of miconazole nitrate mucoadhesive tablets in comparison with itraconazole capsules for OC treatment. Methods The study was a randomized, open-label, parallel-armed, multicenter clinical trial. Totally, 343 patients diagnosed with OC, who met the inclusion criteria, were randomly assigned to either a treatment group that received miconazole nitrate mucoadhesive tablets (10 mg) once daily or a control group that received itraconazole capsules (100 mg QD) for 2 weeks, and were followed up for 2 weeks. The clinical cure, improvement of clinical symptoms/signs, mycologic cure, and safety were evaluated. Results The mucoadhesive tablets (n = 171) did not show inferiority to itraconazole (n = 172) in the treatment of OC. At the end of the 14-day treatment, the clinical cure rates were 45.29% and 41.76% in the miconazole and itraconazole groups, respectively (P = 0.3472). At the end of the 14-day follow-up, the clinical cure rates were 51.18% and 41.76% in the miconazole and itraconazole groups, respectively (P = 0.0329). Adverse events occurred in 53 subjects (33 in the miconazole group and 20 in the itraconazole group). There was no statistical difference in the safety profile between miconazole and itraconazole (P = 0.0533). Thrombocytopenic purpura, although rare, occurred in one patient in the miconazole group and was considered a drug-related, severe adverse event. Conclusion Miconazole nitrate mucoadhesive tablets may be as effective as systemic itraconazole capsule for OC treatment. Physicians should be cautious about thrombocytopenic purpura occurring as a rare and serious adverse event of miconazole

    Few randomized studies have reported on the use of factor IX (FIX) for secondary prophylaxis in haemophilia B patients. This study aimed to evaluate the efficacy and safety of two secondary prophylaxis regimens of recombinant coagulation FIX, nonacog alfa, compared with on-demand therapy. Male subjects aged 6-65 years with severe or moderately severe haemophilia B (FIX:C ≤ 2, n = 50) and ≥12 bleeding episodes (including ≥6 haemarthroses episodes) within 12 months of study participation were enrolled in this multicentre, randomized, open-label, four-period crossover trial. The primary measure was the annualized bleeding rate (ABR) of two prophylactic regimens vs. on-demand therapy. In the intent-to-treat group, mean ABR values were 35.1, 2.6 and 4.6 for the first on-demand period, the 50 IU kg(-1) twice-weekly period, and the 100 IU kg(-1) once-weekly period respectively. Differences in ABR between the first on-demand period and both prophylaxis regimens were significant (P < 0.0001); no significant differences were observed between prophylaxis regimens (P = 0.22). Seven serious adverse events occurred in five subjects, none related to study drug. Results demonstrated that secondary prophylaxis therapy with nonacog alfa 50 IU kg(-1) twice weekly or 100 IU kg(-1) once weekly reduced ABR by 89.4% relative to on-demand treatment. Both prophylaxis regimens demonstrated favourable safety profiles in subjects with haemophilia B.

    Background: Catechins and epicatechins are monomers of naturally occurring proanthocyanidins, which have been reported with free radical scavenging, antioxidant, antiinflammatory, antiallergic, and vasodilatory properties. Plant parts rich in proanthocyanidins have been used for years in treatment of various ano-rectal diseases. This study compares the efficacy of two herbal preparations, Daflon® 500 mg and Roidosanal®, in ameliorating the signs and symptoms associated with hemorrhoids. Objective: To evaluate the safety and to compare the efficacy of a herbal preparation, Roidosanal® versus Daflon® 500 mg, on signs and symptoms of hemorrhoidal disease. Materials and Methods: In this pilot, active controlled, open-labeled multicentre study, 73 patients with proctoscopy proven hemorrhoids (Grade I to III) were randomly assigned to receive either Roidosanal® (Gr R; n = 37) or Daflon® 500 mg (Gr D; n = 36), for 15 days, at three centers in India. Assessment of hemorrhoidal symptoms was carried out in all patients at different time points. Intent-to-treat analysis was performed for both primary and secondary endpoints. Results: Baseline characteristics were comparable between the two groups. Both products were found to be equally effective in improving the ano-rectal conditions in Grade I and Grade II hemorrhoids; however, Roidosanal® demonstrated better efficacy in patients with Grade III hemorrhoids. Hemorrhoids associated symptoms like bleeding, pain, etc., improved in both groups, although intergroup comparisons were comparable. Conclusion: Both Roidosanal® and Daflon® 500 mg were equally effective in resolving signs and symptoms of hemorrhoids. Roidosanal® can be tried as a safe and effective treatment option for treatment of hemorrhoids. Further randomized, double-blind and large multicentre studies are recommended. PMID:24948863

    Chronic hepatitis C is the most common indication for liver transplantation, but viral recurrence is universal and progressive graft injury occurs in most recipients. Our aim was to assess the safety, pharmacokinetics (PK), and antiviral effects of high doses of a human hepatitis C antibody enriched immune globulin product (HCIG) in patients undergoing liver transplantation for chronic hepatitis C. This was a multicenter, randomized, open-label, controlled trial conducted at 4 transplant centers in the United States. A total of 18 patients with chronic hepatitis C, who underwent liver transplantation, were randomized to receive low-dose HCIG (75 mg/kg) or high-dose HCIG (200 mg/kg), or no treatment. A total of 17 infusions of HCIG were administered in each treated patient over 14 weeks using a time-dependent dosing strategy based on the PK of anti-hepatitis B immune globulin in liver transplant recipients. Hepatitis C virus levels, liver enzymes, and liver biopsies were obtained serially throughout the study period. PK profiles of HCV antibodies were determined on days 4, 10, and 98. HCIG infusions were safe and tolerated. The infusion rate could not be maximized because of symptoms for 18% to 30% of the doses. The half-life of HCIG was extremely short immediately after transplantation but was gradually prolonged. In the high-dose group, serum alanine aminotransferase (ALT) levels normalized in most subjects and no patient developed hepatic fibrosis. However, serum HCV RNA levels were not suppressed at either dose. In conclusion, HCIG, an anti-HCV enriched immune globulin product, appears to be safe in patients with chronic hepatitis C undergoing liver transplantation. Further studies are required to determine whether the drug has beneficial effects in this group of patients.

    Background: Migraine headaches are the most common acute and recurrent headaches. Current treatment of a migraine headache consists of multiple medications for control and prevention of recurrent attacks. Global emergence of alternative medicine led us to examine the efficacy of cupping therapy plus serkangabin syrup in the treatment of migraine headaches. Materials and Methods: This study was a randomized, controlled, open-label, comparative efficacy trial. We randomly assigned patients with migraine into cupping therapy plus serkangabin group (30 patients) and conventional treatment group (30 patients). An investigator assessed the severity of headache, frequency of attacks in a week and duration of attacks per hour in 5 visits (at the end of 2 weeks, 1, 3 and 6 months). Generalized estimating equations approach was used to analyze repeated measures data to compare outcomes in both groups. Results: Average age for cupping therapy group and conventional treatment group were 31.7 (±7.6) and 32.6 (±12.7) years, respectively (P = 0.45). After treatment for 2 weeks; and 1, 3 and 6 months, severity of headache (P = 0.80), frequency of migraine attacks (P = 0.63) and duration of attacks per hours (P = 0.48) were similar in conventional and cupping groups but these symptoms were decreased in each group during the study (P < 0.001). Conclusion: There was no significant difference between cupping plus serkangabin therapy and conventional treatment in the treatment and prophylaxis of migraine. The alternative therapy may be used in cases of drug intolerance, no medication response, and in primary care. PMID:25709653

    The present study was conducted to compare the effectiveness and tolerability of fluoxetine and sertraline in the treatment of undifferentiated somatoform disorder (USD), using the Patient Health Questionnaire (PHQ-15), which was specifically designed for assessing the severity of somatic symptoms. A randomized, 12-week, open-label trial of fluoxetine (10-60 mg/d) and sertraline (25-350 mg/d) in patients with USD was conducted. Six visits, at baseline and weeks 1, 2, 4, 8, and 12, were scheduled. Assessments for effectiveness and tolerability were conducted at each visit. The primary effectiveness measure was the mean change in PHQ-15 total score, from baseline to the end of treatment. Secondary effectiveness measures were the mean changes in total scores on the Beck Depression Inventory (BDI) and the 12-item General Health Questionnaire (GHQ-12), from baseline to the end of treatment. A total of 45 subjects were enrolled; of them, 28 were randomly assigned to receive fluoxetine and 17 to receive sertraline. The total score on the PHQ-15 from baseline to the end of treatment significantly decreased in the fluoxetine (-10.7, p<0.0001) and sertraline (-10.3, p<0.0001) treatment groups, with no between-group difference (F=0.0701, p=0.7924). Overall, both treatments were well tolerated and no serious adverse event was reported. This study suggests that both agents may have a potential role in the treatment of USD. A double-blind, placebo-controlled trial and/or head-to-head comparison study with larger samples are required to draw more definite conclusions.

    Due to the low uptake, adherence, and completion of vaccination among drug users, and their compromised immune responses to hepatitis B vaccination, the current practice of hepatitis B vaccination may not provide optimal protection. The aim of this study was to evaluate the immunogenicity and safety of 60 µg and 20 µg hepatitis B vaccines among drug users. A randomized, open-labeled, blank-controlled trial was conducted among drug users at 2 drug rehabilitation centers in China. The eligible participants were drug users who were serologically negative for the hepatitis B surface antigen (HBsAg) and the hepatitis B surface antibody (anti-HBs). Participants were randomized in a ratio of 1:1:1 to receive 20 µg (IM20 group) or 60 µg (IM60 group) of hepatitis B vaccine or blank control at months 0, 1, and 6, and followed at months 6, 7, and 12. Seroconversion rates of 94.7% and 92.6% were observed in IM20 and IM60 groups at month 7, and correspondingly decreased to 89.5% and 91.7% respectively at month 12. The IM60 group showed significantly higher geometric mean concentrations (GMCs) of anti-HBs (2022.5 and 676.7 mIU mL-1) than the IM20 group did (909.6 and 470.5 mIU mL-1) at months 7 and 12 (P < 0.05). No safety concerns associated with vaccination were noted. Three-dose intramuscular immunization with hepatitis B vaccines showed good immunogenicity among the drug users.

    Aims To compare efficacy and safety of two, once-daily basal insulin formulations [insulin lispro protamine suspension (ILPS) vs. insulin glargine (glargine)] added to oral antihyperglycaemic medications (OAMs) and exenatide BID in suboptimally controlled type 2 diabetes (T2D) patients. Methods This 24-week, open-label, multicentre trial randomized patients to bedtime ILPS (n = 171) or glargine (n = 168). Non-inferiority of ILPS versus glargine was assessed by comparing the upper limit of 95% confidence intervals (CIs) for change in haemoglobin A1c (HbA1c) from baseline to week 24 (adjusted for baseline HbA1c) with non-inferiority margin 0.4%. Results Non-inferiority of ILPS versus glargine was demonstrated: least-squares mean between-treatment difference (ILPS minus glargine) (95% CI) was 0.22% (0.06, 0.38). Mean HbA1c reduction was less for ILPS- versus glargine-treated patients (−1.16 ± 0.84 vs. −1.40 ± 0.97%, p = 0.008). Endpoint HbA1c < 7.0% was achieved by 53.7% (ILPS) and 61.7% (glargine) (p = NS). Overall hypoglycaemia rates (p = NS) and severe hypoglycaemia incidence (p = NS) were similar. Nocturnal hypoglycaemia rate was higher in patients treated with ILPS versus glargine (p = 0.004). Weight gain was similar between groups (ILPS: 0.27 ± 3.38 kg; glargine: 0.66 ± 3.93 kg, p = NS). Endpoint total insulin doses were lower in patients treated with ILPS versus glargine (0.30 ± 0.17 vs. 0.37 ± 0.17 IU/kg/day, p < 0.001). Conclusions ILPS was non-inferior to glargine for HbA1c change over 24 weeks, but was associated with less HbA1c reduction and more nocturnal hypoglycaemia. Treat-to-target basal insulin therapy improves glycaemic control and is associated with minimal weight gain when added to OAMs and exenatide BID for suboptimally controlled T2D. PMID:24298995

    Chronic management of schizophrenia and schizoaffective disorders is frequently complicated by symptomatic relapse. An open-label, randomized, active-controlled, 2-year trial evaluated 710 patients with schizophrenia or related disorders who were switched from stable treatment with oral risperidone, olanzapine, or conventional neuroleptics to risperidone long-acting injectable (RLAI) or oral quetiapine. Primary effectiveness evaluation was time-to-relapse. Safety evaluations included adverse events (AEs) reported for the duration of the study, Extrapyramidal Symptom Rating Scale (ESRS), clinical laboratory tests, and vital signs. A total of 666 patients (n=329 RLAI, n=337 quetiapine) were evaluable for effectiveness measures. Baseline demographics were similar between treatment groups. Kaplan–Meier estimate of time-to-relapse was significantly longer with RLAI (p<0.0001). Relapse occurred in 16.5% of patients with RLAI and 31.3% with quetiapine. RLAI and quetiapine were both safe and well tolerated. Weight gain affected 7% of patients with RLAI and 6% with quetiapine, with mean end point increases of 1.25±6.61 and 0±6.55 kg, respectively. There were no significant between-group differences in weight gain. ESRS total scores decreased similarly after randomization to either RLAI or quetiapine. Extrapyramidal AEs occurred in 10% of patients with RLAI and 6% with quetiapine. Treatment-emergent potentially prolactin-related AEs were reported in 15 (5%) patients with RLAI and 5 (2%) patients with quetiapine; hyperprolactinemia was reported in 43 (13.1%) patients with RLAI and 5 (1.5%) patients with quetiapine. Somnolence occurred in 2% of patients with RLAI and 11% with quetiapine. To our knowledge, this is the first report of a randomized clinical trial directly comparing relapse prevention with a second-generation long-acting injectable antipsychotic and oral therapy. Time-to-relapse in stable patients with schizophrenia or schizoaffective disorder was

    Background Intracavitary electrocardiogram (IC ECG) guidance emerges as a new technique for peripherally inserted central catheters (PICCs) placement and demonstrates many potential advantages in recent observational studies. Aims To determine whether IC ECG-guided PICCs provide more accurate positioning of catheter tips compared to conventional anatomical landmarks in patients with cancer undergoing chemotherapy. Methods In this multicenter, open-label, randomized controlled study (ClinicalTrials.gov number, NCT02409589), a total of 1,007 adult patients were assigned to receive either IC ECG guidance (n = 500) or anatomical landmark guidance (n = 507) for PICC positioning. The confirmative catheter tip positioning x-ray data were centrally interpreted by independent radiologists. All reported analyses in the overall population were performed on an intention-to-treat basis. Analyses of pre-specified subgroups and a selected large subpopulation were conducted to explore consistency and accuracy. Results In the IC ECG-guided group, the first-attempt success rate was 89.2% (95% confidence interval [CI], 86.5% to 91.9%), which was significantly higher than 77.4% (95% CI, 73.7% to 81.0%) in the anatomical landmark group (P < 0.0001). This trend of superiority of IC ECG guidance was consistently noted in almost all prespecified patient subgroups and two selected large subpopulations, even when using optimal target rates for measurement. In contrast, the superiority nearly disappeared when PICCs were used via the left instead of right arms (interaction P-value = 0.021). No catheter-related adverse events were reported during the PICC intra-procedures in either group. Conclusions Our findings indicated that the IC ECG-guided method had a more favorable positioning accuracy versus traditional anatomical landmarks for PICC placement in adult patients with cancer undergoing chemotherapy. Furthermore, there were no significant safety concerns reported for catheterization using

    Introduction: Tobacco harm reduction aims to provide reduced risk alternatives to adult smokers who would otherwise continue smoking combustible cigarettes (CCs). This randomized, open-label, three-arm, parallel-group, single-center, short-term confinement study aimed to investigate the effects of exposure to selected harmful and potentially harmful constituents (HPHCs) of cigarette smoke in adult smokers who switched to a carbon-heated tobacco product (CHTP) compared with adult smokers who continued to smoke CCs and those who abstained from smoking for 5 days. Methods: Biomarkers of exposure to HPHCs, including nicotine and urinary excretion of mutagenic material, were measured in 24-hour urine and blood samples in 112 male and female Caucasian smokers switching from CCs to the CHTP ad libitum use. Puffing topography was assessed during product use. Results: Switching to the CHTP or smoking abstinence (SA) resulted in marked decreases from baseline to Day 5 in all biomarkers of exposure measured, including carboxyhemoglobin (43% and 55% decrease in the CHTP and SA groups, respectively). The urinary excretion of mutagenic material was also markedly decreased on Day 5 compared with baseline (89% and 87% decrease in the CHTP and SA groups, respectively). No changes in biomarkers of exposure to HPHCs or urinary mutagenic material were observed between baseline and Day 5 in the CC group. Conclusions: Our results provide clear evidence supporting a reduction in the level of exposure to HPHCs of tobacco smoke in smokers who switch to CHTP under controlled conditions, similar to that observed in SA. Implications: The reductions observed in biomarkers of exposure to HPHCs of tobacco smoke in this short-term study could potentially also reduce the incidence of cancer, cardiovascular and respiratory diseases in those smokers who switch to a heated tobacco product.

    This study was a 14-day, outpatient, open-label randomized crossover trial of lyophilized black raspberries (BRBs) in older overweight or obese males to determine whether BRB consumption affects postprandial inflammation associated with consumption of a high-fat high-calorie (HFHC) meal. Ten study participants consumed 45 g/d of lyophilized BRBs for 4 days, followed by a HFHC breakfast plus BRBs on day 6 or consumed the HFHC breakfast on day 6 without previous consumption of BRBs and then crossed over to the other treatment after a 2-day washout period. Blood samples were obtained before and 1, 2, 4, 8, and 12 hours after consumption of the HFHC breakfast. The primary study outcomes were changes in area under the concentration-time curve (AUC) for interleukin-6 (IL-6), C-reactive protein (CRP), and tumor necrosis factor-alpha (TNF-α). The secondary outcomes were safety and tolerability of lyophilized BRB powder. The chronology and values of measured serum concentrations for IL-6, TNF-α, and CRP were consistent with those described previously by other investigators. The AUC of serum IL-6 was lowered significantly (P = 0.03, n = 10) with BRB consumption (34.3 ± 7.6 pg·mL⁻¹·h⁻¹ compared with 42.4 ± 17.9 pg·mL⁻¹·h⁻¹ for consumption of the HFHC meal alone). However, no significant differences (change in AUC) were calculated for serum CRP and TNF-α. The findings of this pilot study suggest that consumption of lyophilized BRBs may attenuate postprandial inflammation in overweight or obese males consuming a HFHC meal. Further investigation of BRBs is warranted to better elucidate their inflammomodulatory potential.

    The objective of this study was to assess the efficacy and tolerability of YM155, a survivin suppressor, in combination with docetaxel, compared with docetaxel alone in patients with HER2-negative metastatic breast cancer. This phase II, multicenter, open-label, 2-arm study randomized patients (≥18 years) with histologically or cytologically confirmed stage IV HER2-negative metastatic breast cancer and ≥1 measurable lesion, to receive docetaxel alone or docetaxel plus YM155. The primary endpoint was progression-free survival (PFS). Secondary endpoints included objective response rate (ORR), overall survival (OS), duration of response (DOR), clinical benefit rate (CBR), time to response (TTR), biomarker assessment, and analysis of circulating tumor cells. Patients were women diagnosed with HER2-negative breast cancer; most had received prior drug therapies. The median PFS was 8.4 months with YM155 plus docetaxel (n = 50) and 10.5 months with docetaxel alone (n = 51; HR 1.53; 95 % CI 0.83, 2.83; P = 0.176). No statistically significant differences were observed for secondary endpoints, although slightly greater OS (630 vs 601 days; P = 0.768), CBR (84.3 vs 82.0 %; P = 0.855), DOR, and TTR were observed with docetaxel alone compared with YM155 plus docetaxel, whereas ORR was similar (25.5 vs 26.0). The most common TEAEs observed with YM155 plus docetaxel compared with docetaxel alone were neutropenia (83.3 vs 84.3 %), alopecia (62.5 vs 52.9 %), fatigue (50 vs 41.2 %), and nausea (37.5 vs 41.2 %). Although YM155 is a novel drug that suppresses survivin, YM155 plus docetaxel exhibited no statistically significant differences in endpoints compared with docetaxel alone. The combination regimen was well tolerated.

    Background: HIV-infected, treatment-experienced adults with a history of prior resistance and regimen failure can be virologically suppressed but may require multitablet regimens associated with lower adherence and potential resistance development. Methods: We enrolled HIV-infected, virologically suppressed adults with 2-class to 3-class drug resistance and at least 2 prior regimen failures into this phase 3, open-label, randomized study. The primary endpoint was the percentage of participants with HIV-1 RNA <50 copies per milliliter at week 24 [Food and Drug Administration (FDA) snapshot algorithm]. Results: For 135 participants [elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) plus darunavir (DRV), n = 89; baseline regimen, n = 46], most of whom were taking a median of 5 tablets/d, simplification to E/C/F/TAF plus DRV was noninferior to continuation of baseline regimens at week 24 (plasma HIV-1 RNA <50 copies per milliliter: 96.6% vs. 91.3%, difference 5.3%, 95.001% CI: −3.4% to 17.4%). E/C/F/TAF plus DRV met prespecified criteria for noninferiority and superiority at week 48 for the same outcome. E/C/F/TAF plus DRV was well tolerated and had an improved renal safety profile compared with baseline regimens, with statistically significant differences between groups in quantitative total proteinuria and markers of proximal tubular proteinuria. Compared with baseline regimens, participants who switched to E/C/F/TAF plus DRV reported higher mean treatment satisfaction scale total scores and fewer days with missed doses. Conclusions: This study demonstrated that regimen simplification from a 5-tablet regimen to the 2-tablet, once-daily combination of E/C/F/TAF plus DRV has durable maintenance of virologic suppression and improvements in specific markers of renal safety. Such a strategy may lead to greater adherence and improved quality of life. PMID:27753684

    To investigate the pharmacokinetics of inhaled batefenterol (BAT) and fluticasone furoate (FF) given alone or in combination via ELLIPTA® dry powder inhaler (DPI-E), and BAT monotherapy via DISKUS® DPI (DPI-D). In this open-label, 6-way crossover study, 48 healthy subjects were randomized to 1 of 6 treatment sequences, comprising 6 single-dose treatment regimens: (1) BAT 1200 μg via DPI-D; (2) BAT 1200 μg via DPI-E without a lactose-filled second strip; (3) BAT 1200 μg via DPI-E with a lactose-filled second strip; (4) BAT/FF 1200/300 μg via DPI-E; (5) FF 300 μg via DPI-E with a lactose-filled second strip; and (6) BAT/FF 900/300 μg via DPI-E. Pharmacokinetic data were analyzed using noncompartmental methods. Plasma BAT area under the curve (AUC) and maximum plasma concentration (Cmax ) were similar for all treatments containing BAT 1200 μg (geometric least-squares means [GLSM] ratio, 0.90-1.06). Plasma FF AUC and Cmax were reduced following BAT/FF 1200/300 μg and 900/300 μg versus FF 300 μg monotherapy (GLSM ratio, 0.62-0.77). BAT 1200 μg administered via DPI-E, alone or in combination with FF, resulted in similar systemic exposure versus BAT administered by DPI-D. FF exposure was reduced when administered in combination with BAT compared with FF alone.

    The search for new macrofilaricidal drugs against onchocerciasis that can be administered in shorter regimens than required for doxycycline (DOX, 200mg/d given for 4–6 weeks), identified minocycline (MIN) with superior efficacy to DOX. Further reduction in the treatment regimen may be achieved with co-administration with standard anti-filarial drugs. Therefore a randomized, open-label, pilot trial was carried out in an area in Ghana endemic for onchocerciasis, comprising 5 different regimens: the standard regimen DOX 200mg/d for 4 weeks (DOX 4w, N = 33), the experimental regimens MIN 200mg/d for 3 weeks (MIN 3w; N = 30), DOX 200mg/d for 3 weeks plus albendazole (ALB) 800mg/d for 3 days (DOX 3w + ALB 3d, N = 32), DOX 200mg/d for 3 weeks (DOX 3w, N = 31) and ALB 800mg for 3 days (ALB 3d, N = 30). Out of 158 randomized participants, 116 (74.4%) were present for the follow-up at 6 months of whom 99 participants (63.5%) followed the treatment per protocol and underwent surgery. Histological analysis of the adult worms in the extirpated nodules revealed absence of Wolbachia in 98.8% (DOX 4w), 81.4% (DOX 3w + ALB 3d), 72.7% (MIN 3w), 64.1% (DOX 3w) and 35.2% (ALB 3d) of the female worms. All 4 treatment regimens showed superiority to ALB 3d (p < 0.001, p < 0.001, p = 0.002, p = 0.008, respectively), which was confirmed by real-time PCR. Additionally, DOX 4w showed superiority to all other treatment arms. Furthermore DOX 4w and DOX 3w + ALB 3d showed a higher amount of female worms with degenerated embryogenesis compared to ALB 3d (p = 0.028, p = 0.042, respectively). These results confirm earlier studies that DOX 4w is sufficient for Wolbachia depletion and the desired parasitological effects. The data further suggest that there is an additive effect of ALB (3 days) on top of that of DOX alone, and that MIN shows a trend for stronger potency than DOX. These latter two results are preliminary and need confirmation in a fully randomized controlled phase 2 trial. Trial

    Introduction A multicenter, open-label phase III study was conducted to test whether sunitinib plus paclitaxel prolongs progression-free survival (PFS) compared with bevacizumab plus paclitaxel as first-line treatment for patients with HER2− advanced breast cancer. Patients and Methods Patients with HER2− advanced breast cancer who were disease free for ≥ 12 months after adjuvant taxane treatment were randomized (1:1; planned enrollment 740 patients) to receive intravenous (I.V.) paclitaxel 90 mg/m2 every week for 3 weeks in 4-week cycles plus either sunitinib 25 to 37.5 mg every day or bevacizumab 10 mg/kg I.V. every 2 weeks. Results The trial was terminated early because of futility in reaching the primary endpoint as determined by the independent data monitoring committee during an interim futility analysis. At data cutoff, 242 patients had been randomized to sunitinib-paclitaxel and 243 patients to bevacizumab-paclitaxel. Median PFS was shorter with sunitinib-paclitaxel (7.4 vs. 9.2 months; hazard ratio [HR] 1.63 [95% confidence interval (CI), 1.18–2.25]; 1-sided P = .999). At a median follow-up of 8.1 months, with 79% of sunitinib-paclitaxel and 87% of bevacizumab-paclitaxel patients alive, overall survival analysis favored bevacizumab-paclitaxel (HR 1.82 [95% CI, 1.16–2.86]; 1-sided P = .996). The objective response rate was 32% in both arms, but median duration of response was shorter with sunitinib-paclitaxel (6.3 vs. 14.8 months). Bevacizumab-paclitaxel was better tolerated than sunitinib-paclitaxel. This was primarily due to a high frequency of grade 3/4, treatment-related neutropenia with sunitinib-paclitaxel (52%) precluding delivery of the prescribed doses of both drugs. Conclusion The sunitinib-paclitaxel regimen evaluated in this study was clinically inferior to the bevacizumab-paclitaxel regimen and is not a recommended treatment option for patients with advanced breast cancer.

    Background This Phase IV, open-label, multicentre, randomized study (MEnTOR) compared two low-dose recombinant human follicle-stimulating hormone (r-hFSH) protocols for ovulation induction. Methods This study was conducted in six Middle Eastern countries between March 2009 and March 2011. Eligible women (18–37 years), with World Health Organization Group II anovulatory infertility, were randomized to receive r-hFSH (starting daily dose: 75 IU) as a chronic low-dose (CLD) (37.5 IU dose increase on Day 14) or low-dose (LD) (37.5 IU dose increase on Day 7) protocol if no follicles were ≥10 mm. The maximum r-hFSH daily dose permitted was 225 IU/day. The total length of ovarian stimulation could not exceed 35 days, unless ultrasound assessment suggested imminent follicular growth and maturation. Patients underwent only one treatment cycle. Primary endpoint: incidence of mono-follicular development. Secondary endpoints included: stimulation duration and rates of bi-follicular development; human chorionic gonadotrophin administration rate; clinical pregnancy; and cycle cancellation (owing to inadequate response). Adverse events (AEs) were recorded. The primary efficacy analysis was performed using data from all patients who received at least one dose of correct study medication, had at least one efficacy assessment, and no protocol violations at treatment start (CLD group, n = 122; LD group, n = 125). Results Mono-follicular development rates (primary endpoint) were similar in both groups (CLD: 56.6% [69/122] versus LD: 55.2% [69/125], p = 0.93; primary efficacy analysis population). Similarly, there were no significant differences between groups in bi-follicular development, clinical pregnancy or cycle cancellation (inadequate response) rates. In patients who received human chorionic gonadotrophin injections, the mean duration of stimulation was 13.7 days in the CLD group and 12.9 days in the LD group. Clinical pregnancy rates for those

    2013-01-01

    Introduction Two replicate randomized, placebo-controlled six-month trials (RCTs) and an open-label treatment extension (OLE) comprised the pegloticase development program in patients with gout refractory to conventional therapy. In the RCTs, approximately 40% of patients treated with the approved dose saw complete response (CR) of at least one tophus. Here we describe the temporal course of tophus resolution, total tophus burden in patients with multiple tophi, tophus size at baseline, and the relationship between tophus response and urate-lowering efficacy. Methods Baseline subcutaneous tophi were analyzed quantitatively using computer-assisted digital images in patients receiving pegloticase (8 mg biweekly or monthly) or placebo in the RCTs, and pegloticase in the OLE. Tophus response, a secondary endpoint in the trials, was evaluated two ways. Overall tophus CR was the proportion of patients achieving a best response of CR (without any new/enlarging tophi) and target tophus complete response (TT-CR) was the proportion of all tophi with CR. Results Among 212 patients randomized in the RCTs, 155 (73%) had ≥1 tophus and 547 visible tophi were recorded at baseline. Overall tophus CR was recorded in 45% of patients in the biweekly group (P = 0.002 versus placebo), 26% in the monthly group, and 8% in the placebo group after six months of RCT therapy. TT-CR rates at six months were 28%, 19%, and 2% of tophi, respectively. Patients meeting the primary endpoint of sustained urate-lowering response to therapy (responders) were more likely than nonresponders to have an overall tophus CR at six months (54% vs 20%, respectively and 8% with placebo). Both overall tophus CR and TT-CRs increased with treatment duration in the OLE, reaching 70% (39/56) of patients and 55% (132/238) of target tophi after one year of treatment in patients receiving pegloticase during both the RCTs and OLE. At that time point, more tophi had resolved in responders (102/145 or 70% of tophi) than

    Although older people are particularly liable to sarcopenia, limited research is available on beta-hydroxy-beta-methylbutyrate (HMB) supplementation in this population, particularly in healthy subjects. In this parallel-group, randomized, controlled, open-label trial, we aimed to evaluate whether an oral supplement containing 1.5 g of calcium HMB for 8 weeks could improve physical performance and muscle strength parameters in a group of community-dwelling healthy older women. Eighty healthy women attending a twice-weekly mild fitness program were divided into two equal groups of 40, and 32 of the treated women and 33 control completed the study. We considered a change in the Short Physical Performance Battery (SPPB) score as the primary outcome and changes in the peak torque (PT) isometric and isokinetic strength of the lower limbs, 6-minute walking test (6MWT), handgrip strength and endurance as secondary outcomes. Body composition was assessed with dual-energy X-ray absorptiometry (DXA) and peripheral quantitative computerized tomography (pQCT). The mean difference between the two groups on pre-post change were finally calculated (delta) for each outcome. After 8 weeks, there were no significant differences between the groups’ SPPB, handgrip strength or DXA parameters. The group treated with HMB scored significantly better than the control group for PT isokinetic flexion (delta = 1.56±1.56 Nm; p = 0.03) and extension (delta = 3.32±2.61 Nm; p = 0.03), PT isometric strength (delta = 9.74±3.90 Nm; p = 0.02), 6MWT (delta = 7.67±8.29 m; p = 0.04), handgrip endurance (delta = 21.41±16.28 s; p = 0.02), and muscle density assessed with pQCT. No serious adverse effects were reported in either group. In conclusion, a nutritional supplement containing 1.5 g of calcium HMB for 8 weeks in healthy elderly women had no significant effects on SPPB, but did significantly improve several muscle strength and physical performance parameters.

    Background India is home to 60% of the total global visceral leishmaniasis (VL) population. Use of long-term oral (e.g. miltefosine) and parenteral drugs, considered the mainstay for treatment of VL, is now faced with increased resistance, decreased efficacy, low compliance and safety issues. The authors evaluated the efficacy and safety of an alternate treatment option, i.e. single infusion of preformed amphotericin B (AmB) lipid emulsion (ABLE) in comparison with that of liposomal formulation (LAmB). Methods In this multicentric, open-label study, 500 patients with VL were randomly assigned in a 3∶1 ratio to receive 15 mg/kg single infusion of either ABLE (N = 376) or LAmB (N = 124). Initial cure (Day 30/45), clinical improvement (Day 30) and long term definitive cure (Day 180) were assessed. Findings A total of 326 (86.7%) patients in the ABLE group and 122 (98.4%) patients in the LAmB group completed the study. Initial cure was achieved by 95.9% of patients in the ABLE group compared to 100% in the LAmB group (p = 0.028; 95% CI: −0.0663, −0.0150). Clinical improvement was comparable between treatments (ABLE: 98.9% vs. LAmB: 98.4%). Definitive cure was achieved in 85.9% with ABLE compared to 98.4% with LAmB. Infusion-related pyrexia (37.2% vs. 32.3%) and chills (18.4% vs. 18.5%) were comparable between ABLE and LAmB, respectively. Treatment-related serious adverse events were fewer in ABLE (0.3%) compared to LAmB (1.6%). Two deaths occurred in the ABLE group, of which one was probably related to the study drug. Nephrotoxicity and hepatotoxicity was not observed in either group. Conclusions ABLE 15 mg/kg single infusion had favorable efficacy and was well tolerated. Considering the demographic profile of the population in this region, a single dose treatment offers advantages in terms of compliance, cost and applicability.

    Background Traditional Chinese medicine (TCM) has been used to treat chronic obstructive pulmonary disease (COPD) for many years. This study aimed to evaluate the efficacy and safety of the comprehensive therapy based on the three common TCM patterns in stable COPD patients. Methods A four-center, open-label randomized controlled method was conducted. A total of 352 patients were divided into the trial group (n = 176, treated with conventional Western medicine and Bu-Fei Jian-Pi granules, Bu-Fei Yi-Shen granules, and Yi-Qi Zi-Shen granules based on the TCM patterns respectively) and the control group (n = 176, treated with conventional Western medicine). The frequency and duration of acute exacerbation, lung function, clinical symptoms, 6-minute walking distance (6MWD), dyspnea scale and quality of life were observed during a 6-month treatment period and at a further 12-month follow-up. Results A total of 306 patients completed the study fully. The full analysis set (FAS) population was 350 and the per-protocol analysis set (PPS) population was 306. After the 6-month treatment and 12-month follow-up, there were significant differences between the trial and control group in the following: frequency of acute exacerbation (FAS: P = 0.000; PPS: P = 0.000); duration of acute exacerbation (FAS: P = 0.000; PPS: P = 0.001); FEV1 (FAS: P = 0.007; PPS: P = 0.008); symptoms (FAS: P = 0.001; PPS: P = 0.001); 6MWD (FAS: P = 0.045; PPS: P = 0.042); dyspnea scale (FAS: P = 0.002; PPS: P = 0.004); and physical domain (FAS: P = 0.000; PPS: P = 0.000), psychological domain (FAS: P = 0.008; PPS: P = 0.011), social domain (FAS: P = 0.001; PPS: P = 0.000) and environment domain (FAS: P = 0.015; PPS: P = 0.009) of the WHOQOL-BREF questionnaire. There were no differences between the trial and control group in FVC, FEV1% and adverse events. Conclusions Based on the TCM patterns, Bu-Fei Jian-Pi granules, Bu-Fei Yi-Shen granules and Yi-Qi Zi-Shen granules have beneficial effects on measured

    We sought to assess the accuracy and safety of the ESAT6-CFP10 reagent in diagnosing tuberculosis (TB) disease. An open-label, randomized phase 2a trial was conducted in 56 healthy adults and 88 TB patients at one medical centre and one teaching hospital in China. All participants received 0.1, 0.5, 1 or 2 μg ESAT6-CFP10 in their right forearm. Moreover, 56 healthy volunteers and 56 patients were given tuberculin-purified protein derivative (TB-PPD) in their left forearm. The remaining 32 patients were administered placebo. The main outcome measure was induration diameter. An enzyme-linked immunospot (ELISPOT) assay was conducted before the skin test. The ESAT6-CFP10 test caused a higher positivity rate than placebo (81.2% (26/32) vs. 3.1% (1/32); p <0.001). The median maximum induration diameter after ESAT6-CFP10 injection was 17.0 (interquartile range (IQR), 14.0-21.7) mm, similar to that for TB-PPD (17.5 (IQR, 7.0-30.5) mm). The diagnostic accuracy of ESAT6-CFP10 was superior to that of TB-PPD (area under the receiver operating characteristic curve (AUC), 0.870 (95% confidence interval (CI), 0.796-0.944) vs. 0.686 (95% CI, 0.585-0.786); p <0.001). When analysed in all participants, ESAT6-CFP10 had comparable AUC values to the ELISPOT assay (0.849 (95% CI, 0.835-0.952) vs. 0.908 (95% CI, 0.852-0.965)). Local itching (12/144, 8.3%) and pain (26/144, 18.1%) were the main side effects of ESAT6-CFP10. No serious adverse events were reported. The ESAT6-CFP10 skin test appears to be a safe and promising tool; further testing will confirm its efficacy in identifying TB disease.

    The safety and tolerability of vortioxetine in adults with major depressive disorder was assessed. Tolerability was based on the nature, incidence and severity of treatment-emergent adverse events (TEAEs) during acute (6/8) week treatment in 11 randomized, double-blind placebo-controlled short-term studies in major depressive disorder: six with an active reference. Symptoms following discontinuation were assessed through the Discontinuation-Emergent Signs and Symptoms checklist in three studies. Long-term (⩽52 weeks) tolerability was evaluated in five open-label extension studies. Patients (n =5701) were acutely treated with either placebo (n=1817), vortioxetine (5-20mg/day; n=3018), venlafaxine XR (225mg/day; n=113) or duloxetine (60mg/day; n=753). The withdrawal rate due to TEAEs during treatment with vortioxetine (5-20mg/day) was 4.5-7.8%, compared with placebo (3.6%), venlafaxine XR (14.2%) or duloxetine (8.8%). Common TEAEs (incidence ⩾5% and >2 × placebo) with vortioxetine (5-20mg/day) were nausea (20.9-31.2%) and vomiting (2.9-6.5%). For vortioxetine (5-20mg/day), the incidence of TEAEs associated with insomnia was 2.0-5.1% versus 4.0% for placebo, and with sexual dysfunction 1.6-1.8% versus 1.0% for placebo. Discontinuation symptoms as assessed by the mean Discontinuation-Emergent Signs and Symptoms total score after abrupt discontinuation were comparable to placebo in the first and second week. Vortioxetine had no effect relative to placebo on clinical laboratory parameters, body weight, heart rate or blood pressure. Vortioxetine showed no clinically relevant effect on ECG parameters, including the QTcF interval. In long-term treatment, no new types of TEAEs were seen; the mean weight gain was 0.7-0.8kg. Thus, vortioxetine (5-20mg/day) appears safe and generally well tolerated in the treatment of major depressive disorder.

    The safety and tolerability of vortioxetine in adults with major depressive disorder was assessed. Tolerability was based on the nature, incidence and severity of treatment-emergent adverse events (TEAEs) during acute (6/8) week treatment in 11 randomized, double-blind placebo-controlled short-term studies in major depressive disorder: six with an active reference. Symptoms following discontinuation were assessed through the Discontinuation-Emergent Signs and Symptoms checklist in three studies. Long-term (⩽52 weeks) tolerability was evaluated in five open-label extension studies. Patients (n =5701) were acutely treated with either placebo (n=1817), vortioxetine (5–20mg/day; n=3018), venlafaxine XR (225mg/day; n=113) or duloxetine (60mg/day; n=753). The withdrawal rate due to TEAEs during treatment with vortioxetine (5–20mg/day) was 4.5–7.8%, compared with placebo (3.6%), venlafaxine XR (14.2%) or duloxetine (8.8%). Common TEAEs (incidence ⩾5% and >2 × placebo) with vortioxetine (5–20mg/day) were nausea (20.9–31.2%) and vomiting (2.9–6.5%). For vortioxetine (5–20mg/day), the incidence of TEAEs associated with insomnia was 2.0–5.1% versus 4.0% for placebo, and with sexual dysfunction 1.6–1.8% versus 1.0% for placebo. Discontinuation symptoms as assessed by the mean Discontinuation-Emergent Signs and Symptoms total score after abrupt discontinuation were comparable to placebo in the first and second week. Vortioxetine had no effect relative to placebo on clinical laboratory parameters, body weight, heart rate or blood pressure. Vortioxetine showed no clinically relevant effect on ECG parameters, including the QTcF interval. In long-term treatment, no new types of TEAEs were seen; the mean weight gain was 0.7–0.8kg. Thus, vortioxetine (5–20mg/day) appears safe and generally well tolerated in the treatment of major depressive disorder. PMID:26864543

    We studied the effectiveness of olanzapine/fluoxetine combination (OFC) treatment of bipolar depressive episode (7 weeks, study period 1 [SP1]). Study period 1 responders (mean modal daily OFC dosage, 10.8/27.8 mg) were randomized to OFC continuation treatment or olanzapine (OLZ) monotherapy starting at 10 mg (12 weeks, SP2). Seventy-three percent of the 114 patients who entered into SP2 completed the trial. The Montgomery-Åsberg Depression Rating Scale total score changes from baseline in SP1 (primary outcome) were significant (−20 ± 10, P < 0.001) and, during SP2, worsened for patients in the OLZ group (OFC vs OLZ, −0.4 ± 7.55 vs +8.2 ± 14.1, respectively; P < 0.001). During SP1, 69% responded and 59% remitted. During SP2, significantly more patients in the OFC group maintained response (31.3% vs 12.5%) and remission (71.4% vs 39.6%) than patients in the OLZ group. Treatment-emergent adverse events with OFC (SP1 and SP2) included increased appetite, increased weight, somnolence, anxiety, insomnia, and depressed mood. Since visit 1, the mean weight increases (in pounds) were 4.8 ± 6.8 for SP1 (P < 0.001) and 6.3 ± 10.3 (OFC) or 10.7 ± 11.3 (OLZ) for SP2; 50% (OLZ) and 33% (OFC) of the patients had a 7% or higher weight increase. For cholesterol, triglycerides, and low-density lipoprotein levels and some hepatic enzymes, there were statistically and clinically significant changes in both study periods but no differences between the SP2 groups. Study limitations included the open-label design and exclusion of the SP1 nonresponders from SP2. These study results suggest that improvements resulting from 7 weeks of acute OFC treatment of a bipolar depressive episode are maintained in responders for an additional 12 weeks with OFC, but switching to OLZ alone may result in symptom worsening.

    Inhaled umeclidinium (UMEC) and the combination of inhaled UMEC with vilanterol (UMEC/VI) are approved maintenance treatments for chronic obstructive pulmonary disease in the US and EU. This was a randomized, open-label, three-period crossover, single- and repeat-dose study to assess the pharmacokinetics (PK), safety, and tolerability of inhaled UMEC/VI 62.5/25 μg (delivering 55/22 μg) and UMEC/VI 125/25 μg (delivering 113/22 μg) compared with their monotherapy components (UMEC 62.5 μg, UMEC 125 μg and, VI 25 μg [delivering 55, 113, and 22 μg, respectively]) in healthy Chinese subjects (n=20). UMEC and VI were rapidly absorbed following single and repeat dosing (time to maximum plasma concentration [tmax]: UMEC = 5 min; VI = 5 min). The median tlast was 2–4 h for UMEC and 1–2 h for VI following single doses of UMEC/VI and UMEC monotherapy (both doses). UMEC reached steady-state prior to Day 10; steady-state for VI could not be assessed. UMEC accumulation following repeat dosing was 11–34% based on Cmax and 19–59% based on area under the concentration-time curve from time zero to 2 h (AUC(0-2)). VI accumulation following repeat dosing was 25–66% based on Cmax and 17–43% based on AUC(0-2). The evidence was not sufficient to suggest that systemic exposure was substantially different between UMEC/VI combination therapy and the constituent monotherapies following single or repeat dosing. Following both single- and repeat-dose administration, the inter-subject coefficient of variation for all UMEC PK parameter estimates ranged from 12% to 165% for all treatments, indicating a wide range of variability in inhaled PK parameters. Twelve subjects experienced ≥1 adverse event (AE). Six subjects experienced ≥1 treatment-related AE; the most commonly reported treatment-related AE was chest discomfort (n=3 [15%]). No clinically important changes in vital signs or electrocardiogram parameters were reported. These data suggest that single- and repeat

    OBJECTIVES: The purpose of this study was to determine the efficacy and safety of the nicotine patch for smoking cessation in an over-the-counter environment. The years of study were 1994 to 1995. METHODS: Parallel 6-week trials were conducted: a placebo-controlled trial of no-cost 22-mg, 24-hour nicotine patch therapy and an open label trial of the same therapy with patches purchased by subjects. Participants (n = 958) were 18 years or older, had smoked at least 15 cigarettes daily for at least 6 months, and were enrolled at 3 study sites. The main outcome measure was self-reported smoking abstinence confirmed by expired carbon monoxide measurements. RESULTS: Smoking cessation rates in the placebo-controlled trial were 16.8% and 9.6% at week 6 and 8.7% and 4.3% at week 24 for the active patch and placebo groups, respectively. Smoking cessation rates in the open label-pay trial were 19.0% and 10.8% at weeks 6 and 24, respectively. A slight increase in adverse cardiovascular events was noted only in the open label-pay group in comparison with the placebo group. CONCLUSIONS: In an over-the-counter environment, the 22-mg, 24-hour nicotine patch is effective and safe for smoking cessation treatment. PMID:10553392

    We assessed the 24-week efficacy and safety of teneligliptin, a novel dipeptidyl peptidase-4 inhibitor, in Korean patients with type 2 diabetes mellitus (T2DM) that was inadequately controlled with diet and exercise. The present study was designed as a multicentre, randomized, double-blind, placebo-controlled, parallel-group, phase III study. Patients (n = 142) were randomized 2 : 1 into two different treatment groups as follows: 99 received teneligliptin (20 mg) and 43 received placebo. The primary endpoint was change in glycated haemoglobin (HbA1c) level from baseline to week 24. Teneligliptin significantly reduced the HbA1c level from baseline compared with placebo after 24 weeks. At week 24, the differences between changes in HbA1c and fasting plasma glucose (FBG) in the teneligliptin and placebo groups were -0.94% [least-squares (LS) mean -1.22, -0.65] and -1.21 mmol/l (-1.72, -0.70), respectively (all p < 0.001). The incidence of hypoglycaemia and adverse events were not significantly different between the two groups. This phase III, randomized, placebo-controlled study provides evidence of the safety and efficacy of 24 weeks of treatment with teneligliptin as a monotherapy in Korean patients with T2DM.

    The present study aimed to investigate the pharmacokinetic properties of febuxostat in healthy Chinese male volunteers and evaluate whether the two formulations of febuxostat 40-mg and 80-mg tablets are bioequivalent. A randomized, open-label, 4-way crossover study was conducted in healthy Chinese male volunteers under fasting conditions. 24 eligible subjects were randomized in a 1:1:1:1 ratio to receive a single dose of test or reference formulation of febuxostat 40-mg or 80-mg tablet. The washout period between each administration was 1 week. Plasma febuxostat was quantified by a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. Tolerability was evaluated by monitoring adverse events, physical examinations, 12-lead ECG and laboratory tests. After single-dosing of 1 tablet of 40-mg febuxostat, the pharmacokinetic parameters of test and reference formulations were: Tmax 1.22±0.87 and 1.85±1.03 h, Cmax 1689.16±461.31 and 1613.80±608.43 ng·mL-1, AUC0-t 5139.87±1349.28 and 5517.91±2024.26 ng·mL-1·h, AUC0−∞ 5263.06±1339.16 and 5640.48±2040.22 ng·mL-1·h, t1/2 4.82±2.61 and 4.85±1.78 h, respectively. After single-dosing of 1 tablet of 80-mg febuxostat, the pharmacokinetic parameters of test and reference formulations were: Tmax 1.71±1.21 and 2.23±1.55 h, Cmax 2744.47±1157.44 and 2998.17±1200.13 ng·mL-1, AUC0-t 9634.03±2768.25 and 10467.95±3501.65 ng·mL-1·h, AUC0−∞ 9834.32±2730.51 and 10626.63±3504.08 ng·mL-1·h, t1/2 6.25±2.44 and 5.46±1.65 h, respectively. For single-dosing of 1 tablet of 40-mg febuxostat, 90% CIs for the test/reference ratio of AUC0-t, AUC0−∞ and Cmax were 89.79 to 102.55, 90.14 to 102.56 and 93.99 to 129.63, respectively. For single-dosing of 1 tablet of 80-mg febuxostat, 90% CIs for the test/reference ratio of AUC0-t, AUC0−∞ and Cmax were 86.67 to 100.00, 87.50 to 100.51 and 79.48 to 105.99, respectively.

    A 2-year, randomized, double-blind, placebo-controlled study in men with osteoporosis demonstrated that treatment with risedronate 35mg once a week significantly decreased bone turnover markers (BTMs) and increased bone mineral density (BMD). This study was extended to include a 2-year, open-label extension to continue to assess the safety and efficacy of risedronate in men with osteoporosis. In the open-label extension, all patients received risedronate 35mg once a week, and 1000mg elemental calcium and 400 to 500IU vitamin D daily for up to 2 years. The safety of risedronate was evaluated based on adverse events, laboratory data, vital signs, and physical examination results. BMD, BTMs, and the incidence of new vertebral fractures were also assessed. A total of 218 (of 284) patients enrolled in the open-label extension. Risedronate continued to produce significant increases in lumbar spine BMD from baseline (7.87%) in the group of patients who took it for 4 years. Risedronate produced significant increases in lumbar spine BMD from baseline (6.27%) in the former placebo group who took it for 2 years during the open-label extension. Few new vertebral and clinical fractures occurred during the study. There were no significant differences in BTMs between the two groups at months 36 and 48. Incidences of any upper GI adverse events during the extension were low and similar in the two groups; however, the percent of moderate to severe events were higher (8% versus 2%) in the group that received placebo prior to the extension. Safety results continued to show that risedronate was well-tolerated in men with osteoporosis. Patients who received risedronate 35mg once a week for 2years in the open-label extension study showed similar safety and efficacy results compared with those who received risedronate treatment in the first 2 double-blind years of the study. Patients who received risedronate for 4 years in total showed similar safety and efficacy to that observed in

    The objective of this exploratory, multicenter, randomized, double-blind study, was to evaluate the efficacy and safety/tolerability of milnacipran and venlafaxine administered at flexible doses (100, 150 or 200 mg/day, bid administration) for 24 weeks (including 4 weeks up titration period) in the outpatient treatment of adults presenting with a moderate or severe episode of major depressive disorder (MDD) without high suicidal risk (MINI-DSM IV-TR). Of the 195 patients included, 134 (68.7%) completed the study. At baseline the two groups were similar, except there was a higher proportion of patients whose episode was severe-DSM IV in the milnacipran group (63.3% versus 54.0% in the venlafaxine group). The initial MADRS score (mean 31.0) decreased progressively during the study, and this decrease was in the two treatment groups (n = 177: 90 milnacipran; 87 venlafaxine) at week 24 (observed case/OC, mean change -23.1 milnacipran; -22.4 venlafaxine). The rate of MADRS response (reduction >/= 50%) at week 8 and week 24-last observation carried forward/LOCF was similar in the two groups (week 8: 64.4% milnacipran; 65.5% venlafaxine; week 24: 70% milnacipran; 77% venlafaxine), as was the rate of MADRS remission (score

    Hyperprolactinemia, an adverse effect associated with the use of typical antipsychotics and the atypical antipsychotic risperidone, has both acute and chronic clinical consequences. One option for clinical management is switching to an agent with a lower liability for inducing hyperprolactinemia. This post-hoc sub-analysis of an 8-week, open-label study in outpatients with schizophrenia (CN138-215) examined short-term effects on prolactin levels during a switch from risperidone or olanzapine to aripiprazole 30 mg/day. Three switch strategies were used: (I) immediate aripiprazole initiation with simultaneous immediate discontinuation of olanzapine/risperidone; (II) immediate aripiprazole initiation while tapering off olanzapine/risperidone over 14 days; (III) titrating aripiprazole upwards while tapering off olanzapine/risperidone over 14 days. Changes in prolactin levels from baseline to each last observation carried forward time point were compared with t-tests using Bonferroni correction for multiple comparisons. This sub-analysis included 269 subjects: 105 previously treated with risperidone; 164 previously treated with olanzapine. Mean baseline prolactin levels (ng/mL) were within normal range for the three olanzapine groups (Group-I, 11.7; Group-II, 13.2; Group-III, 11.2), but above normal for the risperidone groups (Group-I, 39.7; Group-II, 48.5; Group-III, 33.5). Following aripiprazole initiation, mean prolactin levels decreased significantly (p<0.001) at week-1 and were maintained to week-8 in all groups irrespective of prior treatment. Previously elevated prolactin levels in the risperidone groups were reduced to within normal range within 1 week, irrespective of switching strategy. Tolerability was good regardless of prior medication or switching strategy. Overall, rapid decreases of prolactin levels were achieved safely with all three aripiprazole switching strategies. Reversal of hyperprolactinemia during the crossover period indicates the safety and

    Background: This open-label, crossover study examined lisdexamfetamine dimesylate (LDX) and d-amphetamine pharmacokinetics in healthy adults after administration of an intact LDX capsule or after the capsule was emptied into orange juice or yogurt and the contents consumed. Methods: Healthy adult volunteers (N = 30) were administered a 70-mg LDX capsule or the contents of a 70-mg capsule mixed with yogurt or orange juice using a 3-way crossover design. Blood samples were collected serially for up to 96 hours after dose. Pharmacokinetic endpoints included maximum plasma concentration (Cmax) and area under the plasma concentration versus time curve from zero to infinity (AUC0–∞) or to last assessment (AUClast). Relative LDX and d-amphetamine bioavailabilities from the contents of a 70-mg LDX capsule mixed with orange juice or yogurt were compared with those from the intact LDX capsule using bioequivalence-testing procedures. Results: Geometric least squares mean ratios (90% confidence intervals [CIs]) for d-amphetamine (active moiety) were within the prespecified bioequivalence range (0.80–1.25) when the contents of a 70-mg LDX capsule were mixed with orange juice [Cmax: 0.971 (0.945, 0.998); AUC0–∞: 0.986 (0.955, 1.019); AUClast: 0.970 (0.937, 1.004)] or yogurt [Cmax: 0.970 (0.944, 0.997); AUC0–∞: 0.945 (0.915, 0.976); AUClast: 0.944 (0.912, 0.977)]. Geometric least squares mean ratios (90% CIs) for LDX (inactive prodrug) were below the accepted range when the contents of a 70-mg LDX capsule were mixed with orange juice [Cmax: 0.641 (0.582, 0.707); AUC0–∞: 0.716 (0.647, 0.792); AUClast: 0.708 (0.655, 0.766)]; the lower 90% CI for Cmax [0.828 (0.752, 0.912)] was below the accepted range when the contents of a 70-mg LDX capsule were mixed with yogurt. Conclusions: Relative bioavailability of d-amphetamine (the active moiety) did not differ across administrations, which suggests that emptying an LDX capsule into orange juice or yogurt and consuming it

    Neridronate is a third generation bisphosphonate with established efficacy in metabolic bone disease. In this randomized, open-label study, 118 adults with β-thalassaemia and bone mineral density (BMD) Z scores ≤-2·0 were randomized 1:1-500 mg calcium with 400 international unis (iu) vitamin D daily or 500 mg calcium with 400 iu vitamin D daily plus neridronate 100 mg intravenously every 90 d. Significant increases in BMD at the lumbar spine and total hip were noted in the neridronate group at 6 and 12 months from baseline (P < 0·001), and values were significantly higher than the control group at both time intervals. Neridronate also significantly decreased serum bone alkaline phosphatase and C-telopeptide of collagen type 1 levels from as early as 3 months (P = 0·04 and P < 0·001, respectively), reaching significantly lower values at 12 months compared with the control group (P < 0·05). Reductions in back pain and analgesic use were also evident, starting 3 months from commencing treatment. Treatment was well tolerated by all patients. In this largest randomized trial in thalassaemia-induced osteoporosis to date, neridronate was safe and effective in reducing bone resorption and increasing BMD. The associated reduction in back pain and improved quality of life will encourage adherence to therapy. (Clinicaltrials.gov identifier NCT01140321.).

    Our aim was to design and evaluate a weight-loss program, including a partial meal replacement program, point-of-care testing and face-to-face and smartphone app support, appropriate for delivery in a community pharmacy setting. Overweight or obese adults (n = 146, 71.2% female, 48.18 ± 11.75 years old) were recruited to participate in a 24-week weight loss study and randomised to two app conditions. The dietary intervention was consistent regardless of app. Twelve weeks of clinic appointments with a trained consultant were followed by only app support for an additional 12 weeks. By week 24, retention was 57.5%. There were no differences between app conditions. Based on a cohort analysis of the trial, the mean decrease in weight from baseline to week 24 was 6.43 ± 1.06 kg for males (p < 0.001) and 5.66 ± 0.70 kg for females (p < 0.001). Mixed models also revealed decreases for LDL Cholesterol (-0.13 ± 0.08 mmol/L, nonsignificant), triglycerides (-0.08 ± 0.05 mmol/L, nonsignificant) and an increase in HDL cholesterol (+0.08 ± 0.04 mmol/L, ns) were not significant by week 24. Blood glucose (-0.23 ± 0.08 mmol/L, p = 0.040) and blood pressure (Systolic blood pressure -5.77 ± 1.21 Hg/mm, p < 0.001) were significantly lower at week 24 compared to baseline. Weight loss self-efficacy increased and remained significantly higher than baseline at week 24 (16.85 ± 2.93, p < 0.001). Overall, the program supported participants and was successful in achieving significant weight loss and improvements in health outcomes over 24 weeks.

    Background The doctor-patient encounter (DPE) and associated patient expectations are potential confounders in open-label randomized trials of treatment efficacy. It is therefore important to evaluate the effects of the DPE on study outcomes. Methods Four hundred participants with chronic low back pain (LBP) were randomized to four dose groups: 0, 6, 12, or 18 sessions of spinal manipulation from a chiropractor. Participants were treated three times per week for six weeks. They received light massage control at visits when manipulation was not scheduled. Treating chiropractors were instructed to have equal enthusiasm for both interventions. A path analysis was conducted to determine the effects of dose, patient expectations of treatment success, and DPE on LBP intensity (100-point scale) at the end of care (6 weeks) and primary endpoint (12 weeks). Direct, indirect, and total standardized effects (βtotal) were computed. Expectations and DPE were evaluated on Likert scales. The DPE was assessed as patient-rated perception of chiropractor enthusiasm, confidence, comfort with care, and time spent. Results The DPE was successfully balanced across groups, as were baseline expectations. The principal finding was that the magnitude of the effects of DPE on LBP at 6 and 12 weeks (|β|total = 0.22 and 0.15, p < .05) were comparable to the effects of dose of manipulation at those times (|β|total = 0.11 and 0.12, p < .05). In addition, baseline expectations had no notable effect on follow-up LBP. Subsequent expectations were affected by LBP, DPE, and dose (p < .05). Conclusions The DPE can have a relatively important effect on outcomes in open-label randomized trials of treatment efficacy. Therefore, attempts should be made to balance the DPE across treatment groups and report degree of success in study publications. We balanced the DPE across groups with minimal training of treatment providers. Trial registration ClinicalTrials.gov NCT00376350 PMID

    There are limited clinical trials examining the efficacy of antihypertensive drug combinations aimed at preventing cardiovascular events. Therefore, we designed a randomized controlled trial using amlodipine as the base drug of a multi-drug regimen, the Optimal Combination of Effective ANtihypertensives (OCEAN) Study, to determine the drug combination that is most efficacious in the prevention of cardiovascular events, such as stroke. The OCEAN Study is a collaborative study between Japan and China, enrolling 20 000 patients and following them for 3 to 4 years. A pilot study was conducted before the full-scale study to confirm the feasibility of the protocol and that the study groups and infrastructures could function properly. A total of 279 Japanese patients were enrolled from 57 participating medical institutions between June and December 2004. Two hundred and sixty-six patients (mean age: 65.9 years) were treated with amlodipine alone. One hundred and fifty-four of these patients (57.9%) did not reach the treatment targets (<140/90 mm Hg for the elderly and patients with cerebrovascular disease, <130/80 mm Hg for those with diabetes mellitus, chronic kidney disease or prior myocardial infarction) and a second agent was added. They were randomly allocated into three different treatment groups using a diuretic, a β-blocker or an angiotensin-converting enzyme inhibitor/angiotensin II receptor antagonist. The pilot study showed that the protocol was appropriate, and the inclusion of patients with slightly higher blood pressures was necessary to increase the randomization rate. It also confirmed that we organized properly functioning study groups and infrastructures.

    Recent studies suggest that the intracoronary administration of bone marrow (BM)-derived mesenchymal stem cells (MSCs) may improve left ventricular function in patients with acute myocardial infarction (AMI). However, there is still argumentative for the safety and efficacy of MSCs in the AMI setting. We thus performed a randomized pilot study to investigate the safety and efficacy of MSCs in patients with AMI. Eighty patients with AMI after successful reperfusion therapy were randomly assigned and received an intracoronary administration of autologous BM-derived MSCs into the infarct related artery at 1 month. During follow-up period, 58 patients completed the trial. The primary endpoint was changes in left ventricular ejection fraction (LVEF) by single-photon emission computed tomography (SPECT) at 6 month. We also evaluated treatment-related adverse events. The absolute improvement in the LVEF by SPECT at 6 month was greater in the BM-derived MSCs group than in the control group (5.9% ± 8.5% vs 1.6% ± 7.0%; P=0.037). There was no treatment-related toxicity during intracoronary administration of MSCs. No significant adverse cardiovascular events occurred during follow-up. In conclusion, the intracoronary infusion of human BM-derived MSCs at 1 month is tolerable and safe with modest improvement in LVEF at 6-month follow-up by SPECT.

    Background Data on the potential efficacy of acupuncture (AC) in controlling intense or very intense pain in patients with Herpes Zoster (HZ) has not been so far adequately assessed in comparison with standard pharmacological treatment (ST) by a controlled trial design. Methods Within the VZV Pescara study, pain was assessed in HZ patients on a Visual Analogue Scale (VAS) and by the McGill Pain Questionnaire (MPQ) both at the beginning and at the end of treatment. Response rates, mean changes in pain intensity, differences in total pain burden with an area-under-the-curve (AUC) method over a 1-year follow-up and differences in the incidence of Post-Herpetic Neuralgia (PHN) were evaluated. Results One hundred and two patients were randomized to receive either AC (n = 52) or ST (n = 50) for 4 weeks. Groups were comparable regarding age, sex, pain intensity at presentation and missed antiviral prescription. Both interventions were largely effective. No significant differences were observed in response rates (81.6% vs 89.2%, p = 0.8), mean reduction of VAS (4.1 +/- 2.3 vs 4.9 +/- 1.9, p = 0.12) and MPQ scores (1.3 +/- 0.9 vs 1.3 +/- 0.9, p = 0.9), incidence of PHN after 3 months (48.4% vs 46.8%, p = 0.5), and mean AUC during follow-up (199 +/- 136 vs 173 +/- 141, p = 0.4). No serious treatment-related adverse event was observed in both groups. Conclusions This controlled and randomized trial provides the first evidence of a potential role of AC for the treatment of acute herpetic pain. Trial registration ChiCTR-TRC-10001146. PMID:21639941

    Few studies have examined effectiveness and tolerability of risperidone long-acting injections (RLAI) in the early phase of a schizophrenia spectrum (SS) disorder using a randomized controlled trial (RCT) design. Eighty-five patients in early phase of an SS disorder were randomized to receive either oral second-generation antipsychotics (SGAs; n=41) or RLAI (n=44) over two years. Analyses were conducted on eligible participants (n=77) for the stabilization (maximum 18 weeks) and maintenance phases (up to Week 104) on primary outcome measures of time to stabilization and relapse, change in symptoms and safety, and comparisons made across the two groups. Both groups showed improvement on Positive and Negative Syndrome Scale (PANSS) scores and Clinical Global Impression-Severity (CGI-S) scores. There were no time X group interactions on any of the primary outcome measures. Post hoc examination revealed that the RLAI group showed greater change on CGI-S and PANSS negative symptom scores during the stabilization phase, while the oral group reached the same level of improvement during the maintenance phase. The current exploratory study suggests that-within an RCT design-RLAI and oral SGAs are equally effective and have similar safety profiles in patients in the early phase of SS disorders. Thus, RLAI offers no advantage to patients in early phase of SS disorders, but is likely to be effective and safe for those who may have problems with adherence and may either choose to take it or be prescribed under conditions of external control such as community treatment orders.

    We assessed if St. John's Wort (SJW) improves platelet response in patients (pts) resistant to clopidogrel after percutaneous coronary intervention (PCI). Stable angina pts non-responders to 600 mg clopidogrel (P2Y12 reaction units (PRU) >240) were randomized (2:1) to SJW (n = 15) or placebo (n = 8). SJW (300 mg × 3/day) was administrated for 2 weeks after PCI. Platelet reactivity was assessed by VerifyNowTM before (BL), 2 (T1), and 4 weeks (T2) after PCI. PRU significantly changed during protocol in SJW (BL (316 ± 60) vs. T1 (170 ± 87) vs. T2 (220 ± 96), p < 0.0001) and placebo group (BL (288 ± 36) vs. T1 (236 ± 31) vs. T2 (236 ± 62), p = 0.046). Yet, PRU changes from BL were higher at T1 in SJW than in placebo group (Δ%, -47 ± 24 vs. -16 ± 15, p = 0.0033), with no differences at T2 between the groups (Δ%, -30 ± 29 vs. -17 ± 24, p = 0.30). Residual platelet reactivity improved with SJW during the first month post-PCI.

    This study aimed to compare the efficacy and safety of rituximab (RTX) plus recombinant human thrombopoietin (rhTPO) with RTX alone in patients with immune thrombocytopenia (ITP) who had failed to respond to corticosteroids or relapsed. Recruited patients were randomized at a ratio of 2:1 into 2 groups: the combination group (RTX + rhTPO, n = 77) and the monotherapy group (RTX, n = 38). Overall response was achieved in 79.2% of patients in the combination group vs 71.1% in the monotherapy group (P = .36), and the complete response (CR) rate was 45.4% in the combination group compared with 23.7% in the monotherapy group (P = .026). The combination group had significantly shorter time to response (TTR; median and range, 7 and 4-28 days) compared with the monotherapy group (28 and 4-90 days) (P < .01). There was no difference between these 2 groups in terms of the long-term response (P = .12). Our findings demonstrated that the combination of RTX and rhTPO significantly increased the CR rate and shortened TTR compared with RTX monotherapy in the treatment of corticosteroid-resistant or relapsed ITP but failed to show a beneficial effect on the long-lasting response. This study is registered at www.clinicaltrials.gov as #NCT01525836. PMID:25575541

    SUMMARY Children with GERD may benefit from gastric acid suppression with proton pump inhibitors such as pantoprazole. Effective treatment with pantoprazole requires correct dosing and understanding of the drug’s kinetic profile in children. The aim of these studies was to characterize the pharmacokinetic (PK) profile of single and multiple doses of pantoprazole delayed-release tablets in pediatric patients with GERD aged ≥6 through 11 years (study 1) and 12 through 16 years (study 2). Patients were randomly assigned to receive pantoprazole 20 or 40 mg once daily. Plasma pantoprazole concentrations were obtained at intervals through 12 hours after the single dose, and at 2 and 4 hours after multiple doses for PK evaluation. PK parameters were derived by standard noncompartmental methods and examined as a function of both drug dose and patient age. Safety was also monitored. Pantoprazole PK was dose independent (when dose normalized) and similar toPK reported from adult studies. There was no evidence of accumulation with multiple dosing or reports of serious drug-associated adverse events. In children aged 6 to 16 years with GERD, currently available pantoprazole delayed-release tablets can be used to provide systemic exposure similar to that in adults. PMID:20852004

  12. Sustained treatment effect in attention-deficit/hyperactivity disorder: focus on long-term placebo-controlled randomized maintenance withdrawal and open-label studies.

    Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that often persists throughout life. Approximately two-thirds of patients with a childhood diagnosis of ADHD continue to experience clinically significant symptoms into adulthood. Nevertheless, most of these individuals consider themselves "well," and a vast majority discontinue medication treatment during adolescence. As evidence concerning the adult presentation of ADHD becomes more widely accepted, increasing numbers of physicians and patients will face decisions about the benefits and risks of continuing ADHD treatment. The risks associated with psychostimulant pharmacotherapy, including abuse, dependence, and cardiovascular events, are well understood. Multiple clinical trials demonstrate the efficacy of psychostimulants in controlling ADHD symptoms in the short term. Recent investigations using randomized withdrawal designs now provide evidence of a clinically significant benefit with continued long-term ADHD pharmacotherapy and provide insight into the negative consequences associated with discontinuation. Because many patients lack insight regarding their ADHD symptoms and impairments, they may place a low value on maintaining treatment. Nevertheless, for patients who choose to discontinue treatment, physicians can remain a source of support and schedule follow-up appointments to reassess patient status. Medication discontinuation can be used as an opportunity to help patients recognize their most impairing symptoms, learn and implement behavioral strategies to cope with ADHD symptoms, and understand when additional supportive resources and the resumption of medication management may be necessary.

    This study investigated the effectiveness of diaphragm biofeedback training (DBT) for patients with gastroesophageal reflux disease (GERD). A total of 40 patients with GERD treated at the Peking Union Medical College Hospital between September 2004 and July 2006 were randomized to receive DBT and rabeprazole proton pump inhibitor (PPI) or rabeprazole alone. The DBT + rabeprazole group received DBT during the 8-week initial treatment; the rabeprazole group did not. During the 6-month follow up, all patients took acid suppression according to their reflux symptoms, and the patients in the DBT + rabeprazole group were required to continue DBT. The primary outcome (used for power analysis) was the amount of acid suppression used at 6 months. Secondary outcomes were reflux symptoms, health-related quality of life (HRQL), and esophageal motility differences after the 8-week treatment compared with baseline. Acid suppression usage significantly decreased in the DBT + rabeprazole group compared with the rabeprazole group at 6 months (P < 0.05). At 8 weeks, reflux symptoms and GERD-HRQL were significantly improved in both groups (P < 0.05), without difference between them. Crural diaphragm tension (CDT) and gastroesophageal junction pressure (GEJP) significantly increased in the DBT + rabeprazole group (P < 0.05), but without change in lower esophageal sphincter (LES) pressure. There was no significant change in CDT, GEJP, and LES pressure compared with baseline in the rabeprazole group. In conclusion, long-term DBT could reduce acid suppression usage by enhancing the anti-reflux barrier, providing a non-pharmacological maintenance therapy and reducing medical costs for patients with GERD.

    Background: Melasma is a common acquired cause of facial hyperpigmentation with no definitive therapy. Tranexamic acid, a plasmin inhibitor, has demonstrated depigmenting properties and combining this oral drug with other modalities of treatment has shown promising results. Objectives: To compare the efficacy of a combination of oral tranexamic acid and fluocinolone-based triple combination cream with that of fluocinolone-based triple combination cream alone in melasma among Indian patients. Materials and Methods: 40 patients of melasma of either sex attending to dermatology OPD were enrolled in this study. Participants were randomly divided into two groups with 20 patients in each group. Group A patients were asked to apply the cream only and Group B patients received oral tranexamic acid 250 mg twice daily and applied a triple combination cream containing fluocinolone acetonide 0.01%, tretinoin 0.05%, and hydroquinone 2% once daily for 8 weeks. Response was evaluated using melasma area severity index (MASI) at baseline, 4 weeks, and 8 weeks. Results: 40 patients completed the study. The MASI scores at baseline, 4 weeks and 8 weeks in group A were 15.425 + 1.09, 11.075 + 9.167 and 6.995 + 6.056 respectively and in group B 18.243 + 1.05, 6.135 + 4.94 and 2.19 + 3.38. Intergroup comparison showed a faster reduction in pigmentation in Group B as compared to Group A and the results were statistically significant at 4 weeks (P value 0.014) and 8 weeks (P value 0.000). The efficacy was maintained throughout the 6-month follow-up period. Conclusion: Addition of oral tranexamic acid to fluocinolone-based triple combination cream results in a faster and sustained improvement in the treatment of melasma. PMID:26538719

    The PrePex is a WHO--prequalified medical device for adult male circumcision for HIV prevention. The Government of Rwanda was the first country to implement the PrePex device and acts as the leading center of excellence providing training and formal guidelines. As part of the Government's efforts to improve PrePex implementation, it made efforts to improve the psychological acceptability of device by men, thus increasing uptake with VMMC in sub-Saharan Africa. Some men who underwent the PrePex procedure complained of foreskin odor while wearing the PrePex 3-7 days after it was placed. This complaint was identified as potential risk for uptake of the device. Researchers from Rwanda assumed there is a possible relation between the level of foreskin odor and patient foreskin hygiene technique. The Government of Rwanda decided to investigate those assumptions in a scientific way and conduct a trial to test different hygiene-cleaning methods in order to increase the acceptability of PrePex and mitigate the odor concern. The main objective of the trial was to compare odor levels between three arms, having identical personal hygiene but different foreskin hygiene techniques using either clear water with soap during a daily shower, soapy water using a syringe, or chlorhexidine using a syringe. One hundred and one subjects were enrolled to the trial and randomly allocated into three trial arms. Using chlorhexidine solution daily almost completely eliminated odor, and was statistically significant more effective that the other two arms. The trial results suggest that odor from the foreskin, while wearing the PrePex device, could be related to the growth of anaerobic bacteria, which can be prevented by a chlorhexidine cleaning method. This finding can be used to increase acceptability by men when considering PrePex as one of the leading methods for HIV prevention in VMMC programs.

    Taking metformin with a meal has been shown to decrease bioavailability of metformin. We hypothesized that taking metformin 30 min before a meal improves glucose metabolism. As an animal model, 18 Zucker-rats were divided into three groups as follows: no medication (Control), metformin (600 mg/kg) with meal (Met), and metformin 10 min before meal (pre-Met). In addition, five diabetic patients were recruited and randomized to take metformin (1000 mg) either 30 min before a meal (pre-Met protocol) or with a meal (Met protocol). In the animal model, the peak glucose level of pre-Met (7.8 ± 1.5 mmol/L) was lower than that of Control (12.6 ± 2.5 mmol/L, P = 0.010) or Met (14.1 ± 2.9 mmol/L, P = 0.020). Although there was no statistical difference among the three groups, total GLP-1 level at t = 0 min of pre-Met (7.4 ± 2.7 pmol/L) tended to be higher than that of Control (3.7 ± 2.0 pmol/L, P = 0.030) or Met (3.9 ± 1.2 pmol/L, P = 0.020). In diabetic patients, the peak glucose level of pre-Met protocol (7.0 ± 0.4 mmol/L) was lower than that of Met protocol (8.5 ± 0.9 mmol/L, P = 0.021). Total GLP-1 level at t = 30 min of pre-Met protocol (11.0 ± 6.1 pmol/L) was higher than that of Met protocol (6.7 ± 3.9 pmol/L, P = 0.033). Taking metformin 30 min before a meal ameliorated postprandial hyperglycemia. This promises to be a novel approach for postprandial hyperglycemia.

    Ticagrelor has a greater antiplatelet efficacy than clopidogrel but may be accompanied by an increased risk of bleeding. This study evaluated the antiplatelet effect and pharmacokinetic profile of low-dose ticagrelor in healthy Chinese volunteers. Thirty healthy subjects were randomized to receive standard-dose ticagrelor (180-mg loading dose, 90-mg twice daily [bid] [n = 10]), low-dose ticagrelor (90-mg loading dose, 45-mg bid [n = 10]), or clopidogrel (600-mg loading dose, 75-mg once daily [n = 10]). Platelet reactivity was assessed by using the VerifyNow P2Y12 assay at baseline and 0.5, 1, 2, 4, 8, 24, 48, and 72 hours post-dosing. The ticagrelor and AR-C124910XX concentrations were measured for pharmacokinetic analysis. The percentage inhibition of P2Y12 reaction units was higher in the low-dose and standard-dose ticagrelor group than in the clopidogrel group at 0.5, 1, 2, 4, 8, and 48 hours post-dosing (P < 0.05 for all), but did not differ significantly between the two ticagrelor doses at any time-point (P > 0.05). The plasma ticagrelor and ARC124910XX concentrations were approximately 2-fold higher with standard-dose versus low-dose ticagrelor. No serious adverse events were reported. In conclusion, low-dose ticagrelor achieved faster and higher inhibition of platelet functions in healthy Chinese subjects than did clopidogrel, with an antiplatelet efficacy similar to that of standard-dose ticagrelor.

    Objectives: This phase IIIB study compared the efficacy and safety of febuxostat and allopurinol in gout patients with or without tophi who were HLA-B*5801 negative. Method: Eligible patients were randomized to a febuxostat group (80 mg QD) or an allopurinol group (300 mg QD). Following an initial 2-week washout period, over the next 12 weeks we made five measurements of serum urate levels along with assessments of adverse events (AEs). Results: Forty-three out of 152 screened subjects (28.3%) were ineligible either because of the presence of the HLA-B*5801 allele or for various other reasons. The febuxostat group (n = 54) and the allopurinol group (n = 55) had no significant differences in demographic or baseline characteristics. From week 2 to week 12, the febuxostat group had a significantly lower serum urate level than the allopurinol group (p ≤ 0.001 for all comparisons) and significantly more patients with serum urate levels less than 6.0 mg/dL. The serum urate levels of the febuxostat group declined by more than 40% from week 2 to week 12 and this decrease was greater than that in the allopurinol group (~30%). The two groups were similar in terms of AEs. Conclusions: Febuxostat was more effective than allopurinol in reducing the serum urate levels of Han Chinese patients with gout or tophaceous gout who were HLA-B*5801 negative, without causing any serious skin reactions. Febuxostat should be considered for treatment of Han Chinese patients with gout who are HLA-B*5801 negative. PMID:26771445

    A randomized open-label trial, including 834 pregnant women, examined efficacy and recorded adverse events of ivermectin (ivc) and albendazole (alb) alone and combined (comb) on soil-transmitted helminth infections (STHs) in the second trimester of pregnancy. One abortion occurred in the alb group and 10 stillbirths (1, 5, 3, and 1) in the ivc, alb, comb, and the reference group (ref) with no STHs, respectively. Two babies were born with congenital abnormalities (1 [ivc] and 1 [ref]). The prevalence of anemia at first antenatal care (ANC) visit was 20.6% (23.7% [ivc], 21.1% [alb], 22.2% [comb], and 16.1% [ref]). Anemia was reduced to 8.5% at 36 weeks of gestation with 10.9% (ivc), 11.5% (alb), 7.7% (comb), and 6.9% (ref). Hookworm cure rates were 29.4% (ivc), 95.5% (alb), and 92.6% (comb). No severe adverse events were reported by the women after the administration of ivc, alb, or comb during the second trimester of pregnancy, but long-term pharmacovigillance is needed to assess safety of ivc, alb, or comb in pregnancy.

    In this open-label, randomized study, 36 women (18-45 years) applied an ethinyl estradiol/gestodene contraceptive patch once-weekly for 3 weeks followed by a 1-week, patch-free interval, in 3 treatment periods. The primary objective was to evaluate the pharmacokinetics of ethinyl estradiol and gestodene under conditions of heat, humidity, and exercise. The secondary objective was to evaluate patch adhesion under the same conditions. Weeks 1 and 2 of each period comprised "standardized normal activity" (SNA); in week 3, SNA continued or women used a sauna, whirlpool, swimming pool, or performed an exercise combination. Thirty-one women completed the study; 23 yielded evaluable pharmacokinetic data. Analyses were exploratory and conducted using an analysis of variance. Area under the concentration-time curve from 0 to 168 hours (AUC0-168 ) for gestodene and ethinyl estradiol during sauna, swimming, and whirlpool was equivalent to previous SNA recordings. For exercise combination, the gestodene AUC0-168 was 12% lower compared with SNA, albeit not considered clinically relevant. Two women lost a total of 3 patches during sporting activities; other detachments during this week were not correlated with sporting activity. Overall, hormone delivery using the ethinyl estradiol/gestodene patch under conditions of heat, humidity, and exercise corresponded to delivery under normal conditions.

    An open-labeled randomized study was conducted to compare the immunogenicity and safety of polysaccharide (PPV23) or protein-conjugated pneumococcal vaccine (PCV7) among the elderly aged 80 years or older. A total of 105 nursing home residents were enrolled in this study. We analyzed the geometric mean concentration (GMC) of serotype-specific immunoglobulin G (IgG) and the geometric mean titer (GMT) of the opsonization index (OI) for serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F. The GMCs of serotype-specific IgG and the GMTs of the OI significantly increased one month after vaccination in both groups for all seven serotypes evaluated. In the PCV7 group, study subjects with serotypes 4, 9V, 18C, and 23F exhibited statistically significant elevations in both serotype-specific IgGs and OIs compared to those of the PPV23 group. Both vaccines were tolerated without any severe adverse events, and no differences in systemic adverse events were observed between the two groups, although adverse reactions such as redness and localized swelling were more common in the PCV7 group. Our data demonstrated that the GMCs of serotype-specific IgG and the GMTs of the OI were higher in the PCV7 group compared to those in the PPV23 group. Our study also confirmed the safety of both the PCV7 and PPV23 vaccines in elderly people aged 80 years or older.

    The study was to compare treatment preference, efficacy, and tolerability of sildenafil citrate (sildenafil) and tadalafil for treating erectile dysfunction (ED) in Chinese men naοve to phosphodiesterase 5 (PDE5) inhibitor therapies. This multicenter, randomized, open-label, crossover study evaluated whether Chinese men with ED preferred 20-mg tadalafil or 100-mg sildenafil. After a 4 weeks baseline assessment, 383 eligible patients were randomized to sequential 20-mg tadalafil per 100-mg sildenafil or vice versa for 8 weeks respectively and then chose which treatment they preferred to take during the 8 weeks extension. Primary efficacy was measured by Question 1 of the PDE5 Inhibitor Treatment Preference Questionnaire (PITPQ). Secondary efficacy was analyzed by PITPQ Question 2, the International Index of Erectile Function (IIEF) erectile function (EF) domain, sexual encounter profile (SEP) Questions 2 and 3, and the Drug Attributes Questionnaire. Three hundred and fifty men (91%) completed the randomized treatment phase. Two hundred and forty-two per 350 (69.1%) patients preferred 20-mg tadalafil, and 108/350 (30.9%) preferred 100-mg sildenafil (P < 0.001) as their treatment in the 8 weeks extension. Ninety-two per 242 (38%) patients strongly preferred tadalafil and 37/108 (34.3%) strongly the preferred sildenafil. The SEP2 (penetration), SEP3 (successful intercourse), and IIEF-EF domain scores were improved in both tadalafil and sildenafil treatment groups. For patients who preferred tadalafil, getting an erection long after taking the medication was the most reported reason for tadalafil preference. The only treatment-emergent adverse event reported by > 2% of men was headache. After tadalafil and sildenafil treatments, more Chinese men with ED naοve to PDE5 inhibitor preferred tadalafil. Both sildenafil and tadalafil treatments were effective and safe.

    Objective: The primary aim of the study was to compare the metabolic side effects of a nucleoside analogue-containing regimen with a nucleoside analogue-sparing double protease inhibitor regimen. A secondary goal was to test for efficacy of a double-PI regimen. Design: Multicenter, randomized, open-label, phase III clinical trial. Subjects: Adult HIV-1-infected individuals naïve to antiretroviral therapy with viral load above 400 HIV-RNA copies/ml were randomized (1:1) to either 400 mg lopinavir /100 mg ritonavir (LPV/r) BID plus 150 mg lamivudine/300 mg zidovudine (CBV) BID versus LPV/r BID plus 300 mg atazanavir (ATV) QD. Main outcome measure was the virologic failure in both groups, defined as viral load ≥50 copies/ml at week 48. Results: In the CBV/LPV/r-arm, 29 out of 35 patients [(83%; 95% confidence interval (CI) 66.9-92.2%] and 18 out of 40 patients (45%; 95% CI 29.7-61.5%) in the ATV/LPV/r-arm had a HIV-RNA level <50 copies/ml at week 48. The intent-to-treat analysis revealed inferior virologic response in the ATV/LPV/r arm (Chi-Q and Fisher´s Exact Test p<0.001) and resulted in premature termination of the trial. Eleven patients in the ATV/LPV/r-arm discontinued therapy because of virological failure. These failures mostly presented with low level replication (<1,000 copies/ml). Increases in CD4 cell counts was significantly more rapid in the ATV/LPV/r arm (p=0.02), but comparable at week 48. Conclusions: ATV/LPV/r had less virologic efficacy than the conventional RTI-based regimen and resulted in a high virological failure rate with low level replication. PMID:21643422

    Background: Chronic plaque psoriasis is a common papulosquamous skin disorder, for which a number of topical agents are being used including coal tar, topical steroids and more recently topical calcipotriol/betamethasone dipropionate. There is no study comparing purified coal tar preparation with calcipotriol/betamethasone dipropionate ointment in limited chronic plaque psoriasis. Aims and Objectives: A prospective randomized open label controlled trial to compare the efficacy and safety of topical application of coal tar-salicylic acid ointment with calcipotriol/betamethasone dipropionate ointment applied once at night for 12 weeks for the treatment of limited chronic plaque psoriasis. Materials and Methods: A total of 62 patients of limited chronic plaque psoriasis (body surface area <10%) were randomized into two treatment groups: Group A received topical application of 6% coal tar with 3% salicylic acid ointment and Group B received calcipotriol/betamethasone dipropionate, once at night for 12 weeks. Results were assessed based on psoriasis area severity index (PASI) scores and patient global assessment (PGA) at each visit. Results: Mean PASI was significantly lower at week 2 (P = 0.01) and week 4 follow-up (P = 0.05) and the mean reduction in PASI was significantly higher at week 2 (P = 0.02) with calcipotriol/betamethasone than coal tar-salicylic acid, but this difference was not sustained at subsequent follow-up visits. Similarly, PGA scores at weeks 2 and 4 were significantly lower with calcipotriol/betamethasone dipropionate ointment (P = 0.003 and P = 0.007 respectively). There was no significant difference in any parameter during subsequent follow-up visits or at the end of the treatment phase (12 weeks). Conclusion: Topical nightly application of calcipotriol/betamethasone dipropionate ointment leads to an initial, more rapid reduction in disease severity, but the overall outcome parameters are comparable in the two treatment groups.

    Background: Patients who experience pain, swelling, and trismus after third-molar extraction are reported to experience a 3-fold higher rate of adverse effects (AEs) on quality of life compared with those who are asymptomatic after this surgery. Therefore, investigators emphasize the necessity for better control of this triad of sequelae. Steroids can reduce the risk for physiologic processes of inflammation, thereby suppressing the development of inflammation. Objective: The aim of this study was to compare the effects of dexamethasone 8 mg IM and diclofenac potassium (K) 50 mg PO, dexamethasone 8 mg IM and acetaminophen 1000 mg PO, and monotherapy with diclofenac K 50 mg PO on postoperative pain, swelling, and trismus after surgical removal of third molars. Methods: This prospective, randomized, open-label pilot study was conducted at the Department of Oral and Maxillofacial Surgery, Lagos University Teaching Hospital, Lagos, Nigeria. Patients were randomly allocated to 1 of 3 treatment groups: concomitant treatment with dexamethasone 8 mg IM and diclofenac K 50 mg PO or acetaminophen 1000 mg PO, or monotherapy with diclofenac K 50 mg PO. Overall analgesic efficacy of the drug combinations was assessed for 7 days postoperatively using a 4-point categorical pain-intensity rating scale (0 = no pain; 1 = mild pain; 2 = moderate pain; and 3 = severe pain). Facial swelling was measured in 1 dimension on days 1, 2, and 7 after surgery using a tape measure placed from the tip of the tragus, to gonion, to the tip of the contralateral tragus, and trismus was assessed using interincisal mouth-opening ability, measured using a vernier-calibrated caliper on postoperative days 1, 2, and 7. Tolerability was assessed using direct questioning of the patients at follow-up visits. Results: A total of 150 patients (50 per treatment group) were included in the analysis (76 women, 74 men; mean [SD] age, 26.8 [5.04] years [range, 18–45 years]; 100% Nigerian). The proportion of

    Background and Purpose— We conducted a randomized, open-label, phase 1/2a, dose-escalation study of intraventricular sustained-release nimodipine (EG-1962) to determine safety, tolerability, pharmacokinetics, and clinical effects in aneurysmal subarachnoid hemorrhage. Methods— Subjects with aneurysmal subarachnoid hemorrhage repaired by clipping or coiling were randomized to EG-1962 or enteral nimodipine. Subjects were World Federation of Neurological Surgeons grade 2 to 4 and had an external ventricular drain. Cohorts of 12 subjects received 100 to 1200 mg EG-1962 (9 per cohort) or enteral nimodipine (3 per cohort). The primary objective was to determine the maximum tolerated dose. Results— Fifty-four subjects in North America were randomized to EG-1962, and 18 subjects were randomized to enteral nimodipine. The maximum tolerated dose was 800 mg. One serious adverse event related to EG-1962 (400 mg) and 2 EG-1962 dose-limiting toxicities were without clinical sequelae. There was no EG-1962-related hypotension compared with 17% (3/18) with enteral nimodipine. Favorable outcome at 90 days on the extended Glasgow outcome scale occurred in 27/45 (60%, 95% confidence interval 46%–74%) EG-1962 subjects (5/9 with 100, 6/9 with 200, 7/9 with 400, 4/9 with 600, and 5/9 with 800 mg) and 5/18 (28%, 95% confidence interval 7%–48%, relative risk reduction of unfavorable outcome; 1.45, 95% confidence interval 1.04–2.03; P=0.027) enteral nimodipine subjects. EG-1962 reduced delayed cerebral ischemia (14/45 [31%] EG-1962 versus 11/18 [61%] enteral nimodipine) and rescue therapy (11/45 [24%] versus 10/18 [56%]). Conclusions— EG-1962 was safe and tolerable to 800 mg, and in this, aneurysmal subarachnoid hemorrhage population was associated with reduced delayed cerebral ischemia and rescue therapy. Overall, the rate of favorable clinical outcome was greater in the EG-1962-treated group. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique

    Iron deficiency anemia (IDA) is the most common form of anemia worldwide. Although oral iron is used as first-line treatment, many patients are unresponsive to or cannot take oral iron. This Phase III, open-label, non-inferiority study compared the efficacy and safety of ferumoxytol, a rapid, injectable intravenous (IV) iron product with low immunological reactivity and minimal detectable free iron, with IV iron sucrose in adults with IDA of any cause. Patients (N = 605) were randomized 2:1 to receive ferumoxytol (n = 406, two doses of 510 mg 5 ± 3 days apart) or iron sucrose (n = 199, five doses of 200 mg on five nonconsecutive days over 14 days) and followed for 5 weeks. Ferumoxytol demonstrated noninferiority to iron sucrose at the primary endpoint, the proportion of patients achieving a hemoglobin increase of ≥2 g dL(-1) at any time from Baseline to Week 5 (ferumoxytol, 84.0% [n = 406] vs. iron sucrose, 81.4% [n = 199]), with a noninferiority margin of 15%. Ferumoxytol was superior to iron sucrose (2.7 g dL(-1) vs. 2.4 g dL(-1) ) in the mean change in hemoglobin from Baseline to Week 5 (the alternative preplanned primary endpoint) with P = 0.0124. Transferrin saturation, quality-of-life measures, and safety outcomes were similar between the two treatment groups. Overall, ferumoxytol demonstrated comparable safety and efficacy to iron sucrose, suggesting that ferumoxytol may be a useful treatment option for patients with IDA in whom oral iron was unsatisfactory or could not be used.

    We compared a novel 5% testosterone (T) cream (AndroForte 5, Lawley Pharmaceuticals, Australia) with a 1% T gel (Testogel, Besins Healthcare, Australia). Using an open-label crossover design, subjects were randomized to one of two treatment sequences using either the T gel or T cream first in a 1 : 1 ratio. Each treatment period was 30 days with a 7-14 days washout period between them. On Days 1 and 30 of each treatment period blood was sampled at -15, -5 min, 0, 2, 4, 5, 6, 7, 8, 9, 10, 12 and 16 h post study drug administration. Sixteen men with established androgen deficiency aged between 29 and 73 years, who had undertaken a washout from prior testosterone therapy participated in the study. One subject failed to complete both arms and another was excluded post-completion because of a major protocol violation. Bioequivalence was established based on key pharmacokinetic (PK) variables: AUC, C(avg), C(max), T(max), % fluctuation (with and without baseline correction) for the two formulations of testosterone on Day 1 and Day 30. The ratio and 90% CI of AUC 0.99 (0.86-1.14), C(max) 1.02 (0.84-1.24) and C(avg) 0.99 (0.86-1.14) for T cream/T gel were within the predetermined bio-equivalence criteria of 80% to 125% at Day 30. There were no statistically significant differences between secondary biochemical markers: serum dihydrotestosterone (DHT), oestradiol (E2), sex hormone-binding globulin (SHBG), luteinizing hormone (LH) and (FSH). The two testosterone formulations were shown to be bioequivalent.

    An open-label, randomized, multicenter study was conducted to evaluate the safety and efficacy of long-term use of 2.5% and 5% benzoyl peroxide (BPO) gels administrated once daily for 52 weeks to Japanese patients with acne vulgaris. The efficacy of the study drugs was evaluated by counting inflammatory lesions and non-inflammatory lesions. Safety was evaluated based on adverse events, local skin tolerability scores and laboratory test values. In total, 458 subjects were included in the efficacy and safety analyses. The total lesion count, the efficacy end-point, was similarly changed both in the 2.5% and 5% BPO groups over the course of the study. The median rates of reduction from baseline to week 12 were approximately 65%. Thereafter, the counts were maintained at a reduced level without increasing until week 52. The median rates at week 52 were approximately 80%. Similar trends were observed for inflammatory and non-inflammatory lesion counts. Bacteriological evaluation indicated similar distribution of the minimum inhibitory concentration of each of the antibacterial drugs against Propionibacterium acnes between the values at baseline and at week 52, suggesting that long-term use did not result in changes in the drug sensitivity. The incidence of adverse events was 84.0% in the 2.5% BPO group and 87.2% in the 5% BPO group. Many of the adverse events occurred within the first month and were mild or moderate in severity and transient. The results suggest that both 2.5% and 5% BPO gels are effective and safe for long-term treatment of patients with acne vulgaris.

    Multiple sclerosis (MS) patients initiating IFN beta-1a, Avonex, therapy (Group 1, n = 30) or experiencing side effects after 6 months on therapy (Group 2, n = 30) were randomized for 5 weeks open label adjunct therapy to naproxen (Aleve), acetaminophen (Tylenol) or ibuprofen (Advil). Our hypothesis was that non-prescription pain medications are effective in decreasing or alleviating the side effects associated with IFN beta-1a therapy. Contrary to the hypothesis, most patients in both groups continued to report side effects on all pain medications. After 5 weeks, headache, fever, chills and injection site pain were low in < or = 50% of patients. Moderate to significant fatigue, muscle or joint pain continued in most patients. As a quality of life measure, the Modified Fatigue Impact Scale (mFIS) improved for Group 1 on naproxen or ibuprofen with greatest improvement in physical subset (P = 0.002 for naproxen and P<0.01 for ibuprofen). Total mFIS for Group 1 on acetaminophen improved (P = 0.04) due to improved cognitive subset rather than physical subset. Group 2, with side effects initially, reported less significant fatigue (severity 5-10) but more moderate fatigue (severity 2-4) at study end for all three medications. All medications improved cognitive subset (P = 0.05). Physical mFIS subset did not improve for Group 2 on acetaminophen, but did with naproxen (P = 0.05) or ibuprofen (P = 0.03). Naproxen and ibuprofen were more effective than acetaminophen in minimizing physical side effects of IFN beta-1a. None of the three pain medications tested were as effective as hypothesized for minimizing fatigue or muscle and joint pain.

    Background The World Health Organization recommends intermittent preventive treatment in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP) in African regions with moderate to high malaria transmission. However, growing resistance to SP threatens the effectiveness of IPTp-SP, and alternative drugs are needed. This study tested the efficacy, tolerability, and safety of a fixed-dose combination azithromycin-chloroquine (AZCQ; 250 mg AZ/155 mg CQ base) for IPTp relative to IPTp-SP. Methods and Findings A randomized, Phase 3, open-label, multi-center study was conducted in sub-Saharan Africa (Benin, Kenya, Malawi, Tanzania, and Uganda) between October 2010 and November 2013. Pregnant women received 3 IPTp courses with AZCQ (each course: 1,000/620 mg AZCQ QD for 3 days) or SP (each course 1,500/75 mg SP QD for 1 day) at 4- to 8-week intervals during the second and third trimester. Long-lasting insecticide-treated bednets were also provided at enrollment. Study participants were followed up until day 28 post delivery (time window: day 28–42). The primary endpoint was the proportion of participants with sub-optimal pregnancy outcomes (a composite endpoint comprising live-borne neonates with low birth weight [LBW, <2,500 g], premature birth [<37 weeks], still birth [>28 weeks], abortion [≤28 weeks], lost to follow-up prior to observation of pregnancy outcome, or missing birth weight). The study was terminated early after recruitment of 2,891 of the planned 5,044 participants, due to futility observed in a pre-specified 35% interim analysis. In the final intent-to-treat dataset, 378/1,445 (26.2%) participants in the AZCQ and 342/1,445 (23.7%) in the SP group had sub-optimal pregnancy outcomes, with an estimated risk ratio (RR) of 1.11 (95% CI: 0.97, 1.25; p = 0.12). There was no significant difference in the incidence of LBW between treatment groups (57/1138 [5.0%] in the AZCQ group, 68/1188 [5.7%] in the SP group, RR 0.87 [95% CI: 0.62, 1.23]; p = 0.44). IPTp

    Background In Africa, most plasmodium infections during pregnancy remain asymptomatic, yet are associated with maternal anemia and low birthweight. WHO recommends intermittent preventive therapy in pregnancy with sulfadoxine-pyrimethamine (IPTp-SP). However, sulfadoxine-pyrimethamine (SP) efficacy is threatened by high-level parasite resistance. We conducted a trial to evaluate the efficacy and safety of scheduled intermittent screening with malaria rapid diagnostic tests (RDTs) and treatment of RDT-positive women with dihydroartemisinin-piperaquine (DP) as an alternative strategy to IPTp-SP. Methods and Findings This was an open-label, two-arm individually randomized superiority trial among HIV-seronegative women at three sites in Malawi with high SP resistance. The intervention consisted of three or four scheduled visits in the second and third trimester, 4 to 6 wk apart. Women in the IPTp-SP arm received SP at each visit. Women in the intermittent screening and treatment in pregnancy with DP (ISTp-DP) arm were screened for malaria at every visit and treated with DP if RDT-positive. The primary outcomes were adverse live birth outcome (composite of small for gestational age, low birthweight [<2,500 g], or preterm birth [<37 wk]) in paucigravidae (first or second pregnancy) and maternal or placental plasmodium infection at delivery in multigravidae (third pregnancy or higher). Analysis was by intention to treat. Between 21 July 2011 and 18 March 2013, 1,873 women were recruited (1,155 paucigravidae and 718 multigravidae). The prevalence of adverse live birth outcome was similar in the ISTp-DP (29.9%) and IPTp-SP (28.8%) arms (risk difference = 1.08% [95% CI −3.25% to 5.41%]; all women: relative risk [RR] = 1.04 [95% CI 0.90–1.20], p = 0.625; paucigravidae: RR = 1.10 [95% CI 0.92–1.31], p = 0.282; multigravidae: RR = 0.92 [95% CI 0.71–1.20], p = 0.543). The prevalence of malaria at delivery was higher in the ISTp-DP arm (48.7% versus 40.8%; risk difference

    Background This open-label, randomized study evaluated efficacy and safety of artemether-lumefantrine (AL) and dihydroartemisinin-piperaquine (DP) in treatment of uncomplicated falciparum malaria in children below five years of age, to build evidence on use of AL as first-line treatment and DP as second-line treatment in Kenya. Methods A total of 454 children aged six to 59 months with uncomplicated falciparum malaria were randomized (1:1) to receive AL dispersible or DP paediatric tablets and followed up for 42 days. Primary efficacy variable was corrected adequate clinical and parasitological response (ACPR) rate on day 28. Secondary variables included corrected (day 14, 28 and 42), uncorrected (day 3, 14, 28 and 42) cure rates, parasitological failure at days 3, 14 and 42. Acceptability and tolerability of both drugs were assessed by caregiver questionnaire. Results On day 28, corrected ACPR rates for AL dispersible and DP paediatric were 97.8% (95% CI: 94.9-99.3) and 99.1% (95% CI: 96.8-99.9), respectively, in intention-to-treat population, with no significant treatment differences noted between AL dispersible and DP paediatric arms. Additionally, no significant differences were observed for PCR corrected cure rates on days 14 and ACPR on day 42 for AL dispersible (100%; 96.8%) and DP paediatric (100%; 98.7%). Similarly, for PCR uncorrected cure rates, no significant differences were seen on days 3, 14, 28, and 42 for AL dispersible (99.1%; 98.7%; 81.1%; 67.8%) and DP paediatric (100%; 100%; 87.7%; 70.5%). Parasite clearance was rapid, with approximately 90% clearance achieved in 40 hours in both treatment arms. Incidence of adverse events was related to underlying disease; malaria being reported in both treatment arms.

    We aimed to compare the efficacy and safety of lobeglitazone and pioglitazone as add-ons to metformin in patients with type 2 diabetes. Patients who were inadequately controlled by metformin were randomized and treated once daily with either lobeglitazone (0.5 mg, n = 128) or pioglitazone (15 mg, n = 125) for 24 weeks, with a 28-week extension trial of lobeglitazone treatment in patients who consented. The primary endpoint was the change in glycated haemoglobin (HbA1c) concentration from baseline to week 24. At week 24, the mean change from baseline in HbA1c was -0.74% for the lobeglitazone group and -0.74% for the pioglitazone group, with a mean difference of 0.01% [95% confidence interval (CI) of difference, -0.16 to 0.18]. The effects of lobeglitazone on lipid variables and the adverse events associated with lobeglitazone were similar to those observed with pioglitazone. Lobeglitazone was not inferior to pioglitazone as an add-on to metformin in terms of their efficacy and safety.

    In this phase III, open-label, multicenter, and descriptive study in India, children primed with 3 doses (at ages 6, 10, and 14 weeks) of the 10-valent pneumococcal nontypeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV) were randomized (1:1) to receive a booster dose at 9 to 12 (early booster) or 15 to 18 months old (late booster) in order to evaluate impact of age at booster. We also evaluated a 2-dose catch-up vaccination plus an experimental booster dose in unprimed children age 12 to 18 months. The early booster, late booster, and catch-up vaccinations were administered to 74, 95, and 87 children, respectively; 66, 71, and 81 children, respectively, were included in the immunogenicity according-to-protocol cohort. One month postbooster, for each PHiD-CV serotype, ≥95.2% (early booster) and ≥93.8% (late booster) of the children had antibody concentrations of ≥0.2 μg/ml; ≥96.7% and ≥93.0%, respectively, had opsonophagocytic activity (OPA) titers of ≥8. The postbooster antibody geometric mean concentrations (GMCs) were in similar ranges for early and late boosters; the OPA titers appeared to be lower for most PHiD-CV serotypes (except 6B and 19F) after the early booster. After dose 2 and postbooster, for each PHiD-CV serotype, ≥88.6% and ≥96.3%, respectively, of the catch-up immunogenicity according-to-protocol cohort had antibody concentrations of ≥0.2 μg/ml; ≥71.4% and ≥90.6%, respectively, had OPA titers of ≥8. At least 1 serious adverse event was reported by 2 children in the early booster (skin infection and gastroenteritis) and 1 child in the catch-up group (febrile convulsion and urinary tract infection); all were resolved, and none were considered by the investigators to be vaccine related. PHiD-CV induced robust immune responses regardless of age at booster. Booster vaccination following 2 catch-up doses induced robust immune responses indicative of effective priming and immunological memory. (These studies have

    Background A fixed-dose combination (FDC) of amlodipine and losartan has been used to reduce blood pressure in patients whose hypertension is not sufficiently controlled with either drug alone. The aim of this study was to evaluate the pharmacokinetic (PK) characteristics and tolerability of an FDC of 6.94 mg amlodipine besylate (5 mg as amlodipine)/50 mg losartan potassium compared to an FDC of 5 mg amlodipine camsylate/50 mg losartan potassium in healthy subjects. Subjects and methods A randomized, open-label, single-dose, two-period, two-sequence crossover study was conducted on 46 healthy male subjects. Blood concentrations were measured by liquid chromatography–tandem mass spectrometry. Blood samples were collected up to 144 hours post dose for each period. PK parameters were calculated in each treatment group using a noncompartmental method. The 90% confidence intervals (CIs) of the geometric mean ratios of the two treatments for the maximum plasma concentration (Cmax) and the area under the concentration curve from time zero to the last quantifiable time point (AUC0–t) were estimated. Tolerability assessments were performed for all subjects who received the drug at least once. Results The PK profiles of the two treatments were similar. For amlodipine, the geometric mean ratios (90% CIs) of amlodipine besylate to amlodipine camsylate for the Cmax and AUC0–t were 0.98 (0.94−1.01) and 0.97 (0.93−1.01), respectively. The corresponding values for losartan were 0.91 (0.81−1.02) and 1.05 (0.98−1.12), respectively. The incidence of adverse events was not significantly different between the two treatments, and both were well tolerated. Conclusion An FDC of 6.94 mg amlodipine besylate (5 mg as amlodipine)/50 mg losartan potassium produced similar results to an FDC of 5 mg amlodipine camsylate/50 mg losartan potassium treatment with respect to the PK parameters of amlodipine and losartan based on Cmax and AUC0–t values.

    Background: Enemas are used by individuals with constipation and are often required before certain medical diagnostic procedures and surgical interventions. However, abnormalities in serum electrolyte concentrations have been associated with enema use. Objective: The aim of this study was to determine the changes in serum electrolyte concentrations (phosphorus, calcium, sodium, and potassium) and urinary phosphorus elimination after the administration of a sodium phosphate enema. Methods: Healthy volunteers aged 35 to 70 years were eligible for this open-label, randomized, controlled, 2-period, crossover clinical trial at the Clinical Research Unit of the University Hospital of Navarra, Pamplona, Spain. The study comprised 2 one-day periods separated by a 7-day washout. All subjects were randomly assigned in a 1:1 ratio to 1 of 2 study sequences: (1) a single dose of Enema Casen® 250 mL in the first period followed by no treatment (control) in the second period, or (2) no treatment in the first period followed by a single dose of the study drug in the second period. The sequence of treatment was assigned using a randomization table that was prepared before the beginning of the study. Serum concentrations of phosphorus, sodium, potassium, and calcium were measured in both periods. Urinary phosphorus elimination was measured for 12 hours after enema administration (Ae0–12) in a subset of the subjects in the second period. Adverse events (AEs) were monitored by the investigators throughout the study. Normal ranges for the electrolytes were as follows: phosphorus, 2.5 to 5 mg/dL; calcium, 8.5 to 10.5 mg/dL; sodium, 135 to 145 mEq/L; and potassium, 3.5 to 5 mEq/L. Results: Twenty-four subjects (12 men, 12 women; mean [SD] age, 47.8 [9.6] years [range, 36–68 years]) participated in the study. All of the subjects were white and none were smokers. Twelve hours after enema administration, mean serum phosphorus and sodium concentrations increased by a mean of 1.18 mg

    Objective To evaluate the benefit–risk profile (BRP) of oxycodone/naloxone (OXN) and tapentadol (TAP) in patients with chronic low back pain (cLBP) with a neuropathic component (NC) in routine clinical practice. Methods This was a blinded end point analysis of randomly selected 12-week routine/open-label data of the German Pain Registry on adult patients with cLBP-NC who initiated an index treatment in compliance with the current German prescribing information between 1st January and 31st October 2015 (OXN/TAP, n=128/133). Primary end point was defined as a composite of three efficacy components (≥30% improvement of pain, pain-related disability, and quality of life each at the end of observation vs baseline) and three tolerability components (normal bowel function, absence of either central nervous system side effects, and treatment-emergent adverse event [TEAE]-related treatment discontinuation during the observation period) adopted to reflect BRP assessments under real-life conditions. Results Demographic as well as baseline and pretreatment characteristics were comparable for the randomly selected data sets of both index groups without any indicators for critical selection biases. Treatment with OXN resulted formally in a BRP noninferior to that of TAP and showed a significantly higher primary end point response vs TAP (39.8% vs 25.6%, odds ratio: 1.93; P=0.014), due to superior analgesic effects. Between-group differences increased with stricter response definitions for all three efficacy components in favor of OXN: ≥30%/≥50%/≥70% response rates for OXN vs TAP were seen for pain intensity in 85.2%/67.2%/39.1% vs 83.5%/54.1%/15.8% (P= ns/0.031/<0.001), for pain-related disability in 78.1%/64.8%/43.8% vs 66.9%/50.4%/24.8% (P=0.043/0.018/0.001), and for quality of life in 76.6%/68.0%/50.0% vs 63.9%/54.1%/34.6% (P=0.026/0.022/0.017). Overall, OXN vs TAP treatments were well tolerated, and proportions of patients who either maintained a normal bowel

    Background: Enalapril maleate is the monoethyl ester prodrug of enalapril- at, an angiotensin-converting enzyme inhibitor indicated in the management of essential and renovascular hypertension, and in the treatment of congestive heart failure and in asymptomatic patients with left ventricular dysfunction and an ejection fraction of ≥35%. Enalapril has little pharmacologic activity until hydrolyzed in vivo to enalaprilat. Objective: The aim of the present study was to compare the bioavailability and tolerability of 2 commercial brands (test and reference formulations) of enalapril tablets (20 mg), described as the rate and extent of absorption of the active moiety, to assess their bioequivalence. Methods: This single-dose, randomized, 2-way, open-label, crossover study in healthy volunteers aged 18 to 40 years was conducted at the Clinical Pharmacology Study Unit, Hospital Clínico San Carlos (Madrid, Spain). Subjects were randomized to receive (under fasting conditions) either the test or reference formulation of enalapril (20-mg tablet) at study period 1 and the opposite formulation at study period 2. Study periods were separated by a washout period of at least 7 days. During each study period, 15 plasma extractions were made to determine enalapril and enalaprilat plasma concentrations and to calculate the pharmacokinetic (PK) properties (maximal plasma drug concentration [Cmax], time to Cmax [Tmax], area under the plasma concentration-time curve [AUC] to the last measurable concentration [AUCt], AUC from time 0 to infinity [AUC0−∞], mean residence time, and elimination half-life [tl2]) of both. Physical examination, subject interview, laboratory analyses, electrocardiogram, and blood pressure (BP) were used to assess tolerability. Results: Twenty-four subjects were included in the study (12 men, 12 women; mean [SD] age, 22.8 [2.2] years [range, 19–30 years]). Of these, 1 subject (4.2%) withdrew from the study for personal reasons; thus, PK and statistical

    Abstract Background: The current objective of antiglaucomatous therapy is to reduce intraocular pressure (IOP), and thus to preserve visual function. Many ophthalmologists believe this objective is best achieved by methods that improve ocular blood flow to the optic nerve head. Beta-blockers are effective ocular hypotensive agents, but they can reduce choroidal blood flow. Bimatoprost, a new prostamide analogue, has been shown to have a better IOP-lowering effect compared with the nonselective beta-adrenergic receptor blocker timolol maleate, but little is known about its effects on the vascular bed of the eye. Objective: The aim of this study was to compare the effects of bimatoprost and timolol on IOP and choroidal blood flow (as measured using pulsatile ocular blood flow [pOBF]) in patients with primary open-angle glaucoma (POAG). Methods: This prospective, open-label, randomized, 2-arm, parallel-group study was conducted at the Glaucoma Research Centre, Department of Ophthalmology, University Hospital of Bari, Bari, Italy. Patients with POAG having well-controlled IOP (<16 mm Hg) on monotherapy with timolol 0.5% ophthalmic solution (2 drops per affected eye BID) for ≥12 months but with a progressive decrease in pOBF during the same time period were randomly allocated to 1 of 2 treatment groups. One group continued monotherapy with timolol, 2 drops per affected eye BID. The other group was switched (without washout) to bimatoprost 0.3% ophthalmic solution (2 drops per affected eye QD [9 pm]). Treatment was given for 180 days. IOP and pOBF were assessed at the diagnostic visit (pre-timolol), baseline (day 0), and treatment days 15, 30, 60, 90, and 180. Primary adverse effects (AEs) (ie, conjunctival hyperemia, conjunctival papillae, stinging, burning, foreign body sensation, and pigmentation of periorbital skin) were monitored throughout the study. Results: Thirty-eight patients were enrolled (22 men, 16 women; mean [SD] age, 51.7 [4.8] years; 19 patients per

    Momelotinib, a small-molecule inhibitor of Janus kinase 1 and Janus kinase 2, has demonstrated efficacy in myelofibrosis patients with 300 mg, once-daily dosing. This open-label, non-randomized, phase 1/2 study evaluated the safety and therapeutic benefit of momelotinib with twice-daily dosing. A total of 61 subjects with primary myelofibrosis or post–polycythemia vera/post–essential thrombocythemia myelofibrosis with intermediate- or high-risk disease received momelotinib. A phase 1 dose escalation identified 200 mg twice daily as the optimal dose to be expanded in phase 2. The most frequent adverse events were diarrhea (45.9%), peripheral neuropathy (44.3%), thrombocytopenia (39.3%), and dizziness (36.1%), the latter primarily due to a first-dose effect. The response assessment according to the 2006 International Working Group criteria (≥8 weeks duration at any time point) demonstrated spleen response by palpation of 72% (36/50) and anemia response of 45% (18/40). Spleen response by magnetic resonance imaging obtained at 24 weeks was 45.8% (27/59) for all subjects and 54.0% (27/50) for those with palpable splenomegaly at baseline. The symptoms of myelofibrosis were improved in most subjects. Cytokine analysis showed a rapid decline in interleukin-6 with momelotinib treatment, and a slower reduction in other inflammatory cytokines. In the subgroup of subjects with the JAK2V617F mutation at baseline (n=41), momelotinib significantly reduced the allele burden by 21.1% (median) at 24 weeks. These results provide evidence of tolerability and a potential therapeutic activity of momelotinib for subjects that support further evaluation in ongoing, phase 3 randomized trials.

    Monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma (SMM) represent useful models for studying multiple myeloma precursor disease, and for developing early intervention strategies. Administering a 4g dose of curcumin, we performed a randomised, double-blind placebo-controlled cross-over study, followed by an open-label extension study using an 8g dose to assess the effect of curcumin on FLC response and bone turnover in patients with MGUS and SMM. 36 patients (19 MGUS and 17 SMM) were randomised into two groups: one received 4g curcumin and the other 4g placebo, crossing over at 3 months. At completion of the 4g arm, all patients were given the option of entering an open-label, 8g dose extension study. Blood and urine samples were collected at specified intervals for specific marker analyses. Group values are expressed as mean ± 1 SD. Data from different time intervals within groups were compared using Student's paired t-test. 25 patients completed the 4g cross-over study and 18 the 8g extension study. Curcumin therapy decreased the free light-chain ratio (rFLC), reduced the difference between clonal and nonclonal light-chain (dFLC) and involved free light-chain (iFLC). uDPYD, a marker of bone resorption, decreased in the curcumin arm and increased on the placebo arm. Serum creatinine levels tended to diminish on curcumin therapy. These findings suggest that curcumin might have the potential to slow the disease process in patients with MGUS and SMM.

    Major depressive disorder (MDD), one of the most common psychiatric disorders in the world, is a serious, recurrent and chronic mental disorder, which is associated with significant psychosocial disability and economic burden. Until recently, short-term effectiveness of antidepressants has been measured in terms of patients' response to the medications in significantly reduced depressive symptoms. Remission, a long-term elimination of symptoms and the restoration of normal functioning, has become the primary outcome of therapy. In the current study, the efficacy of three frequently prescribed antidepressants, venlafaxine (75-225 mg/day), paroxetine (20 mg/day) and milnacipran (100 mg/day), used in treating 249 MDD patients with Hamilton Rating Scale of Depression (HRSD₁₇) scores higher than 16 was compared. Each patient was evaluated at week 0, 1, 2, 4, 8, 12, 16, 20 and 24 in a 24-week open-label study. Eighty-two patients took venlafaxine, 97 took paroxetine and 70 patients took milnacipran. No significant differences were found between the three groups in the response condition (HRSD₁₇ scores decreased more than 50%) after 24 weeks of follow-up. For remission, the paroxetine was the least efficacious medication than either the milnacipran (HRSD₁₇ ≤ 7) or the venlafaxine (HRSD₁₇ ≤ 5) by the last observation carried forward (LOCF) analysis. Our results suggest that the absence of depressive symptoms alone may not be an indicator for MDD remission, but the duration of absent depressive symptoms may be a better indicator.

    Objective: Use of zidovudine (ZDV) in antiretroviral therapy is limited by toxicity and twice daily (b.i.d.) dosing. Fozivudine (FZD) is a ZDV prodrug, which is activated intracellularly to ZDV-monophosphate especially in mononuclear cells but not in bone marrow cells. FZD promises improved myelotoxicity and once daily (o.d.) dosing. Design: Randomized clinical trial. Methods: We conducted an open-label, phase II, proof-of-concept trial investigating three different FZD doses (800 mg o.d., 600 mg b.i.d., 1200 mg o.d.) versus ZDV (300 mg b.i.d.) in combination with lamivudine and efavirenz in HIV-infected, ART-naive patients from Tanzania and Côte d’Ivoire. The primary objective was to demonstrate virological efficacy after 24 weeks in intent-to treat and per-protocol analysis. Secondary endpoints included safety and pharmacokinetic outcomes. Results: Of 119 participants included in the intent-to treat analysis, HIV RNA less than 50 copies/ml at 24 weeks was observed in 64 of 88 (73%) patients in the combined FZD arms versus 24 of 31 (77%) in the ZDV arm (RR 0.94, 95% confidence interval 0.75–1.18). In the per-protocol analysis, responses were 64 of 77 (87%) versus 23 of 29 (79%), respectively (RR 1.09, 95% confidence interval 0.89–1.34). Outcomes were similar between FZD arms. Overall, treatments were well tolerated. Severe or worse anaemia occurred in two cases (one related to FZD, one to ZDV), grade III/IV neutropenia was less frequent in FZD compared with ZDV arms (22 versus 42%, P = 0.035). Pharmacokinetic analysis supported o.d. administration of FZD. Conclusion: Virological 24-week efficacy was demonstrated in b.i.d. and o.d. administered FZD-based regimens. Reduced myelotoxicity of FZD needs to be confirmed in a larger trial. PMID:27941394

    The number of open-label extension studies being performed has increased enormously in recent years. Often it is difficult to differentiate between these extension studies and the double-blind, controlled studies that preceded them. If undertaken primarily to gather more patient-years of exposure to the new drug in order to understand and gain confidence in its safety profile, open-label extension studies can play a useful and legitimate role in drug development and therapeutics. However, this can only occur if the open-label extension study is designed, executed, analysed and reported competently. Most of the value accrued in open-label extension studies is gained from a refinement in the perception of the expected incidence of adverse effects that have most likely already been identified as part of the preclinical and clinical trial programme. We still have to rely heavily on post-marketing safety surveillance systems to alert us to type B (unpredictable) adverse reactions because open-label extension studies are unlikely to provide useful information about these types of often serious and relatively rare adverse reactions. Random allocation into test and control groups is needed to produce precise incidence data on pharmacologically expected, or type A, adverse effects. Some increased confidence about incidence rates might result from the open-label extension study; however, as these studies are essentially uncontrolled and biased, the data are not of great value. Other benefits have been proposed to be gained from open-label extension studies. These include ongoing access to an effective but otherwise unobtainable medicine by the volunteers who participated in the phase III pivotal trials. However, there are unappreciated ethical issues about the appropriateness of enrolling patients whose response to previous treatment is uncertain, largely because treatment allocation in the preceding randomised, double-blind, controlled trial has not been revealed at the

    We assessed the efficacy and safety of sitagliptin compared with α-glucosidase inhibitor (αGI) in 120 of Japanese patients with type 2 diabetes mellitus (T2DM) inadequately controlled on stable ≤2 mg/day glimepiride alone [mean hemoglobin A1c (HbA1c) 7.7%] by the randomized, active-controlled, non-inferiority trial. Patients were randomly assigned to receive additional sitagliptin or αGI for 24 weeks. The primary endpoint was change in HbA1c from baseline to week 12. After 12 weeks, sitagliptin reduced HbA1c by -0.44% (p < 0.001) relative to αGI. At 24 weeks, the reduction was almost identical between the groups (-0.091%, p = 0.47). Gastrointestinal disorders were more common with αGI than with sitagliptin, but only minor hypoglycaemia occurred in both groups at similar frequency. These data suggested that sitagliptin was not inferior to αGI for reduction of HbA1c in Japanese T2DM patients receiving glimepiride alone, and well tolerated with minimum risk of gastrointestinal symptoms and hypoglycaemia.

    A phase 3 randomized, multicenter study evaluated the safety and immunogenicity of a combined diphtheria, tetanus, 5-component acellular pertussis, inactivated poliomyelitis, Haemophilus influenzae type b conjugate vaccine (DTaP(5)-IPV/Hib) administered at the same visit with 7-valent pneumococcal conjugate vaccine (PCV7, concurrent group) or at separate visits (separated by ≥ 15 days; staggered group). DTaP(5)-IPV/Hib was administered at 2, 4, 6, and 15 months of age, and PCV7 was administered concurrently or at 3, 5, 7, and 16 months of age. The study results found that DTaP(5)-IPV/Hib is safe and immunogenic when given concurrently with 7-valent pneumococcal conjugate vaccine.

    This study compared barnidipine, a calcium-channel blocker, and benazepril, an angiotensin-converting enzyme inhibitor, in 85 Chinese patients with renal parenchymal hypertension (diastolic blood pressure range 95 - 110 mmHg). Patients were randomly assigned to receive either 10 mg barnidipine or 10 mg benazepril orally daily for 4 weeks. In patients with diastolic blood pressure > 90 mmHg after 2 weeks of treatment, the dose of barnidipine or benazepril was increased by 5 or 10 mg, respectively. Both the barnidipine-treated group (n = 43) and the benazepril-treated group (n = 42) showed significant mean reductions from baseline in sitting systolic and diastolic blood pressures. The decrease in diastolic blood pressure with benazepril was significantly greater than with barnidipine treatment. Sitting heart rate was not changed by either drug. There was no significant difference in adverse events between the two groups. Barnidipine is similar to benazepril for the treatment of renal parenchymal hypertension.

    Vascular calcification (VC) contributes to cardiovascular disease in hemodialysis (HD) patients, especially with diabetes mellitus (DM) complications. No randomized studies have been published regarding the effect of lanthanum carbonate (LC) on VC progression in DM patients. The aim of this study was to evaluate the effects of lanthanum carbonate on the progression of VC in HD patients with type 2 DM. We conducted a randomized controlled trial comparing LC with calcium carbonate (CC) in 43 HD patients at a single dialysis center. Estimations of aortic calcification index (ACI) by abdominal computed tomography were performed twice for each patient (at baseline and 12 months). Forty-one patients completed the study (19 LC, 22 CC). When ACI at baseline was ≦0.48 (median of baseline ACI), median change in ACI (Δ%ACI) was 20.44 (11.50-36.80%) in the LC group, and 40.00 (33.30-92.60%) in the CC group (P = 0.026). On the other hand, when ACI at baseline was >0.48, the median change in ACI (Δ%ACI) was 6.42 (3.13-24.40%) in the LC group, and 8.08 (5.68-12.20%) in the CC group (P = 1.000). Serum markers of chronic kidney disease-mineral and bone disorder (CKD-MBD), HbA1c, dose of vitamin D analogues, and side-effects of medications did not change in either group throughout the study except int-PTH increased in the LC group. This study indicated that administration of LC inhibited the progression of VC in patients receiving HD for type 2 DM, only in cases of slight VC compared with CC.

    Background. Aprepitant is a P/neurokinin-1 receptor antagonist approved for the prevention of CINV in moderate emetic risk chemotherapy. We explored its effectiveness in patients with leukemia receiving cytarabine-based chemotherapy. Methods. Patients were randomized to ondansetron (OND) 8 mg IV 30 minutes before cytarabine followed by 24 mg IV continuous infusion daily until 6-12 hours after the last dose of chemotherapy alone or with aprepitant (APREP) oral 125 mg 6-12 hrs before chemotherapy and 80 mg daily until 1 day after the last dose of chemotherapy. Results. Forty-nine patients were enrolled in each arm; 42 in OND and 41 in OND + APREP arm were evaluable for efficacy. The ORR with OND + APREP was 80% compared to 67% with OND alone (P = 0.11). On days 6 and 7, higher proportion of patients treated with OND + APREP were free from nausea (74%, 74% versus 68%, 67%; P = 0.27 and 0.18, resp.). Requirement of rescue medications on days 2 and 3 was fewer in OND + APREP arm 7% and 5% compared to 21% and 16% in the OND arm, respectively (P = 0.06 and P = 0.07). Conclusions. There was a trend for overall improvement in emesis with ondansetron plus aprepitant. The potential benefit of this approach with specific chemotherapy combinations remains to be determined.

    This trial was conducted to explore the safety of recombinant fusion protein ESAT6-CFP10 as a skin test reagent for the diagnosis of Mycobacterium tuberculosis infection. Twenty-four healthy adult volunteers were recruited and randomized into four groups (groups A to D) to study four increasing doses of ESAT6-CFP10. All subjects in each dose group received an intradermal injection of reagent (0.1 ml) via the Mantoux technique. Then, the vital signs of all subjects were monitored, and skin reactions around injection sites and adverse events were recorded at different detection time points after the skin test. No serious adverse events were observed in this study. A total of 3 subjects had unexpected events. One subject in group A developed subcutaneous hemorrhage 24 h after the skin test, one subject in group B was found with red spots 15 min after the skin test, and another subject in group A showed abnormity during a chest X-ray after the skin test without affecting her health. One of three adverse events (red spots) was probably related to the recombinant ESAT6-CFP10 reagent. A single dose of 1, 5, 10, or 20 μg/ml of recombinant ESAT6-CFP10 as a skin test reagent for M. tuberculosis infection diagnosis is well tolerated and safe in China.

    This study investigated the safety and efficacy of the sodium-glucose co-transporter-2 (SGLT2) inhibitor luseogliflozin with differing carbohydrate intakes in Japanese individuals with type 2 diabetes (T2D). Participants were randomly assigned to 3 carbohydrate-adjusted meals for 14 days (days 1-14; a high carbohydrate [HC; 55% total energy carbohydrate] and high glycaemic index [HGI] meal; an HC [55% total energy carbohydrate] and low glycaemic index [LGI] meal; or a low carbohydrate [LC; 40% total energy carbohydrate] and HGI meal). All participants received luseogliflozin for the last 7 days (days 8-14), continuous glucose monitoring (CGM) before and after luseogliflozin treatment (days 5-8 and days 12-15) and blood tests on days 1, 8 and 15. Luseogliflozin significantly decreased the area under the curve and mean of CGM values in all 3 groups similarly. Fasting plasma glucose, insulin and glucagon were similar at all time points. Ketone bodies on day 15 were significantly higher in the LC-HGI group compared with the HC-HGI and HC-LGI groups. In conclusion, luseogliflozin has similar efficacy and safety in Japanese people with T2D when meals contain 40% to 55% total energy carbohydrate, but a strict LC diet on this class of drug should be avoided to prevent SGLT2 inhibitor-associated diabetic ketoacidosis.

    Background -Radiofrequency catheter ablation for atrial fibrillation has become an important therapy for AF, however recurrence rates remain high. We proposed to determine whether aggressive blood pressure (BP) lowering prevents recurrent atrial fibrillation (AF) after catheter ablation in patients with AF and a high symptom burden. Methods -We randomly assigned 184 patients with AF and a BP greater than 130/80 mmHg to aggressive BP (target <120/80 mm Hg) or standard BP treatment (target <140/90 mmHg) prior to their scheduled AF catheter ablation. The primary outcome was symptomatic recurrence of AF/atrial tachycardia/atrial flutter lasting greater than 30 seconds, determined 3 months beyond catheter ablation by a blinded endpoint evaluation. Results -The median follow-up was 14 months. At six months, the mean systolic BP in the aggressive BP treatment group was 123.2±13.2 versus 135.4±15.7mm Hg (p<0.001) in the standard treatment group. The primary outcome occurred in 106 patients, 54 (61.4%) in the aggressive BP treatment group, compared to 52 (61.2%) in the standard treatment group, (Hazard Ratio 0.94, 95% Confidence Interval 0.65-1.38, p=0.763). In the prespecified subgroup analysis of the influence of age, patients aged ≥ 61 years had a lower primary outcome event rate with aggressive BP (Hazard Ratio 0.58, 95% Confidence Interval (0.34, 0.97), p=0.013). There was a higher rate of hypotension requiring medication adjustment in the aggressive BP group (26% versus 0%). Conclusions -In this study, this duration of aggressive BP treatment did not reduce atrial arrhythmia recurrence after catheter ablation for AF, but resulted in more hypotension.

    Anogenital warts are caused by human papillomavirus (HPV), over 30 types of which are infectious for the anogenital tract. Without treatment, warts may regress spontaneously, remain unchanged, or increase in number and size. This study compared the efficacy of a topical 5% potassium hydroxide (KOH) solution with that of a topical 0.5% 5-fluorouracil (5-FU) and 10% salicylic acid (SA) combination in the treatment of anogenital warts. Sixty patients were randomly assigned to receive topical KOH or 5-FU + SA. Both groups demonstrated a significant decrease in numbers of lesions (P < 0.05), but this difference was not significant at week 12 (P > 0.05). The mean number of lesions decreased from baseline to week 12 from 17.03 ± 12.64 to 3.73 ± 7.30 and from 16.13 ± 12.97 to 3.10 ± 4.90 in the KOH and 5-FU + SA groups, respectively (P < 0.001). Excellent clearance was achieved by 70.0 and 76.7% of patients in the KOH and 5-FU + SA groups, respectively. Marked improvement was seen in 13.3 and 20.0% of patients in the KOH and 5-FU + SA groups, respectively. At week 16, relapse was observed in two patients in the KOH group and three in the 5-FU + SA group (P > 0.05). No serious adverse events were reported. Neither treatment was more efficacious. Safety and ease of application are important goals in treatments for anogenital warts. A 5% KOH solution is a promising alternative treatment because it is effective and inexpensive and causes minimal side effects.

    Saffron (Crocus sativus Linn.) have been perceived by the public as a strong aphrodisiac herbal product. However, studies addressing the potential beneficial effects of saffron on erectile function (EF) in men with ED are lacking. Our aim was to evaluate the efficacy and safety of saffron administration on EF in men with ED. After a 4-week baseline assessment, 346 men with ED (mean age 46.6+/-8.4 years) were randomized to receive on-demand sildenafil for 12 weeks followed by 30 mg saffron twice daily for another 12 weeks or vice versa, separated by a 2-week washout period. To determine the type of ED, penile color duplex Doppler ultrasonography before and after intracavernosal injection with 20 microg prostaglandin E(1), pudendal nerve conduction tests and impaired sensory-evoked potential studies were performed. Subjects were assessed with an International Index of Erectile Function (IIEF) questionnaire, Sexual Encounter Profile (SEP) diary questions, patient and partner versions of the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaire and the Global Efficacy Question (GEQ) 'Has the medication you have been taking improved your erections?' No significant improvements were observed with regard to the IIEF sexual function domains, SEP questions and EDITS scores with saffron administration. The mean changes from baseline values in IIEF-EF domain were +87.6% and +9.8% in sildenafil and placebo groups, respectively (P=0.08). We did not observe any improvement in 15 individual IIEF questions in patients while taking saffron. Treatment satisfaction as assessed by partner versions of EDITS was found to be very low in saffron patients (72.4 vs 25.4, P=0.001). Mean per patient 'yes' responses to GEQ was 91.2 and 4.2% for sildenafil and saffron, respectively (P=0.0001). These findings do not support a beneficial effect of saffron administration in men with ED.

    Renal impairment is associated with poor prognosis in myeloma. This analysis of the pivotal phase 3 FIRST trial examined the impact of renally adapted dosing of lenalidomide and dexamethasone on outcomes of patients with different degrees of renal impairment. Transplant-ineligible patients not requiring dialysis were randomized 1:1:1 to receive continuous lenalidomide and dexamethasone until disease progression (n=535) or for 18 cycles (72 weeks; n=541), or melphalan, prednisone, and thalidomide for 12 cycles (72 weeks; n=547). Follow-up is ongoing. Patients were grouped by baseline creatinine clearance into no (≥ 80 mL/min [n=389]), mild (≥ 50 to < 80 mL/min [n=715]), moderate (≥ 30 to < 50 mL/min [n=372]), and severe impairment (< 30 mL/min [n=147]) subgroups. Continuous lenalidomide and dexamethasone therapy reduced the risk of progression or death in no, mild, and moderate renal impairment subgroups vs. melphalan, prednisone, and thalidomide therapy (HR = 0.67, 0.70, and 0.65, respectively). Overall survival benefits were observed with continuous lenalidomide and dexamethasone treatment vs. melphalan, prednisone, and thalidomide treatment in no or mild renal impairment subgroups. Renal function improved from baseline in 52.6% of lenalidomide and dexamethasone-treated patients. The safety profile of continuous lenalidomide and dexamethasone was consistent across renal subgroups, except for grade 3/4 anemia and rash, which increased with increasing severity of renal impairment. Continuous lenalidomide and dexamethasone treatment, with renally adapted lenalidomide dosing, was effective for most transplant-ineligible patients with myeloma and renal impairment.

    Background. Despite increasing evidence of the development of Plasmodium vivax chloroquine (CQ) resistance, there have been no trials comparing its efficacy with that of artemisinin-based combination therapies (ACTs) in Latin America. Methods. This randomized controlled trial compared the antischizontocidal efficacy and safety of a 3-day supervised treatment of the fixed-dose combination artesunate-amodiaquine Winthrop® (ASAQ) versus CQ for treatment of uncomplicated P. vivax infection in Manaus, Brazil. Patients were followed for 42 days. Primary endpoints were adequate clinical and parasitological responses (ACPR) rates at day 28. Genotype-adjustment was performed. Results. From 2012 to 2013, 380 patients were enrolled. In the per-protocol (PP) analysis, adjusted-ACPR was achieved in 100% (165/165) and 93.6% (161/172) of patients in the ASAQ and CQ arm (difference 6.4%, 95% CI 2.7%; 10.1%) at day 28 and in 97.4% (151/155) and 77.7% (129/166), respectively (difference 19.7%, 95% CI 12.9%; 26.5%), at day 42. Apart from ITT D28 assessment, superiority of ASAQ on ACPR was demonstrated. ASAQ presented faster clearance of parasitaemia and fever. Based on CQ blood level measurements, CQ resistance prevalence was estimated at 11.5% (95% CI: 7.5-17.3) up to day 42. At least one emergent adverse event (AE) was recorded for 79/190 (41x6%) in the ASAQ group and for 85/190 (44x7%) in the CQ group. Both treatments had similar safety profiles. Conclusions. ASAQ exhibited high efficacy against CQ resistant P. vivax and is an adequate alternative in the study area. Studies with an efficacious comparator, longer follow-up and genotype-adjustment can improve CQR characterization. Clinical Trials Registration. NCT01378286. PMID:27988484

    Background Prolonged anti-angiogenic therapy destroys tumor vasculature, whereas vascular-normalizing doses may enhance intra-tumoral drug delivery. We hypothesize that low-dose, short-course sunitinib normalizes vasculature, enhancing chemotherapy efficacy. Patients and Methods In phase Ib, treatment-naïve breast cancer patients received four cycles of pre-operative doxorubicin/cyclophosphamide, with sunitinib before each cycle. The optimal dose of sunitinib leading to tumor vessel normalization on immunohistochemistry was identified. In phase II, subjects were randomized to chemotherapy alone or chemotherapy plus sunitinib at the recommended phase II dose (RP2D). Primary endpoint was pathological complete response (pCR) rate. Tumor and functional imaging biomarkers were evaluated serially. Results In phase Ib (n=9), sunitinib 12.5 mg daily for 7 days before each chemotherapy was established as RP2D. In phase II, patients receiving chemotherapy plus sunitinib (n=24) had similar pCR rates (5.0% versus 4.3%, p=1.00), but a higher incidence of chemotherapy dose delays (33.3% versus 8.7%, p=0.04), compared to those receiving chemotherapy alone (n=25). The addition of sunitinib to chemotherapy significantly increased vascular normalization index (VNI) and decreased lymphatic vessel density (D2-40) on immunohistochemistry [VNI:25.50±27.94% versus 49.29±31.84%, p=0.034; D2-40:3.29±2.70 versus 1.29±1.54, p=0.014, baseline versus post-cycle 1], and improved perfusion on DCE-MRI (Ktrans:12.6±9.6 mL/100 g/min versus 16.3±10.7 mL/100 g/min, baseline versus post-cycle 1, p=0.015). Conversely, immunohistochemical and DCE-MRI parameters were not significantly altered by chemotherapy alone. Conclusion Low-dose, short-course sunitinib prior to anthracycline-based chemotherapy in breast cancer patients did not improve pCR and increased chemotherapy dose delays. However, the addition of sunitinib induced compelling pharmacodynamic evidence of vascular normalization. Further

    Background Development of an optimal interferon-free regimen for chronic hepatitis C virus infection is believed to require the combination of different drug classes to provide good antiviral efficacy, clinical and quality of life benefits, as well as a high barrier to resistance. Viron® is a new herbal drug in film-coated tablet form, and is based on a mixture of herbs with known hepatoprotective and antiviral properties. We conducted this study to explore the safety and the potential clinical and quality of life benefits of this product in patients with chronic hepatitis C infection. Methods Eighty-two consecutive patients presenting to our outpatient clinics as already-known or newly-diagnosed cases of chronic hepatitis C virus (HCV) infection, were entered into the study and randomized to three groups to receive escalating doses of Viron for 6 months. Virological, clinical, and enzyme responses, as well as quality of life index scores for chronic liver disease were compared between the groups. Results Of the 20 patients treated with the highest dose of Viron (three tablets twice daily), two (10%) had a complete virological response at the end of treatment (ETR) and two (10%) had a partial ETR, defined as a decrease in viral load of at least 2-log10 at the end of 6 months of treatment, whereas patients treated with the medium dose (two tablets twice daily) and the lowest dose (one tablet twice daily) showed a significantly lower ETR (P=0.043). Alanine aminotransferase levels and scores on the Chronic Liver Disease Questionnaire improved to a significantly greater extent in the highest dose group (P=0.007 and P=0.021, respectively). No serious adverse effects attributable to the herbal formulation were reported in any of the groups, apart from mild transient nausea, bloating, giddiness, and headache in two patients in the group receiving two tablets twice daily and in three patients in the group receiving three tablets twice daily. Conclusion We conclude that

    The aim of this study was to compare 80 mg telmisartan/5 mg amlodipine/12.5 mg hydrochlorothiazide (T80/A5/H12.5) with 80 mg telmisartan/12.5 mg hydrochlorothiazide (T80/H12.5) to determine their relative blood pressure (BP) lowering effects in essential hypertensive patients with inadequate control and to evaluate the long-term safety of T80/A5/H12.5 in a 52-week extension period. Patients (n=132) were randomly assigned to receive double-blind treatment with T80/A5/H12.5 or T80/H12.5 for 8 weeks after a 6-week run-in-period of T80/H12.5. All 126 patients who completed the double-blind period entered the 52-week open-label extension and received T80/A5/H12.5. The adjusted mean changes from the reference baseline of the trough-seated systolic and diastolic BP (SBP/DBP) at week 8 were significantly larger in the T80/A5/H12.5 group (−10.6/−8.8 mm Hg) than in the T80/H12.5 group (−2.3/−1.3 mm Hg) (P<0.0001). The BP-lowering effect of T80/A5/H12.5 was maintained over the 52-week extension period. The adverse events (AEs) during both treatment periods were generally mild. Drug-related AEs were reported in one patient in each group in the double-blind period and in five patients exposed to T80/A5/H12.5 in the double-blind and/or open-label extension period. T80/A5/H12.5 therapy was clinically and statistically superior to T80/H12.5 therapy for the reduction of BP in patients with essential hypertension uncontrolled with T80/H12.5, and its BP-lowering effect was maintained in the long term. T80/A5/H12.5 was generally well-tolerated. PMID:27581533

    Introduction Plaque-type psoriasis affecting the nails, scalp, hands or feet can often be difficult to treat; for example, topical treatments and phototherapy may not penetrate the nail plate or scalp. The objective of this large, international, multicentre study was to investigate the efficacy of efalizumab in a Latin American population of adult patients with moderate-to-severe chronic plaque psoriasis who were candidates for systemic therapy or phototherapy. Methods Eligible patients were enrolled in a 24-week, open-label, single-arm, Phase IIIb/IV study of continuous treatment with subcutaneous efalizumab, 1.0 mg/kg/wk. Involvement of the nails, scalp, or hands or feet was assessed using the Nail Psoriasis Severity Index (NAPSI), the Psoriasis Scalp Severity Index (PSSI), or the Palmoplantar Pustulosis Psoriasis Area and Severity Index (PPPASI), respectively. Missing data were handled using a last observation carried forward or nonresponder imputation approach. Results Of the 189 patients who received treatment, 112 patients had nail involvement, 172 had scalp involvement, and 19 had palmoplantar disease at baseline. At Week 24, ≥50% improvement on the NAPSI, PSSI and PPPASI was observed in 31%, 71% and 68% of patients, respectively, whereas ≥75% improvement on these scores was observed in 17%, 52% and 63%, respectively. Descriptive statistics showed lower NAPSI-75 and higher PSSI-75 and -50 response rates among patients with higher baseline scores. Conclusions This open-label, uncontrolled study provides supportive evidence of the potential of efalizumab as a treatment for nail, scalp and palmoplantar psoriasis. PMID:20428227

    The relative bioavailability and bioequivalence of 20-mg doses of a pediatric formulation of sildenafil extemporaneous preparation suspension (EP; 10 mg/mL), the sildenafil 20-mg intact tablet and the crushed sildenafil 20-mg tablet mixed with apple sauce were assessed in a single-dose, randomized, open-label, 3-way crossover study with 18 healthy adult volunteers. Blood samples were collected at predefined times and analyzed for sildenafil plasma concentrations. Natural log-transformed sildenafil pharmacokinetic parameters (Cmax , AUClast , and AUCinf ) were used to estimate relative bioavailability and construct 90% confidence intervals (CI) using a mixed-effects model. Bioequivalence was concluded among the three formulations with one exception, in which the EP suspension showed a 15% decrease in Cmax with a lower 90% CI of 76% compared with the intact tablet. The 15% decrease in sildenafil Cmax is not considered to be clinically relevant. Therefore, the EP suspension is considered to be an appropriate pediatric formulation. All 3 formulations were well tolerated in healthy adult volunteers.

    Background Miscarriage occurs in 10% to 15% of pregnancies. The traditional treatment, after miscarriage, has been to perform surgery to remove any remaining pregnancy tissues in the uterus. However, it has been suggested that drug-based medical treatments, or expectant care (no treatment), may also be effective, safe and acceptable. Objectives To assess the effectiveness, safety and acceptability of any medical treatment for early incomplete miscarriage (before 24 weeks). Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (September 2009) and reference lists of retrieved papers. We updated this search on 23 July 2012 and added the results to the awaiting classification section of the review. Selection criteria Randomised controlled trials comparing medical treatment with expectant care or surgery. Quasi-randomised trials were excluded. Data collection and analysis Two authors independently assessed the studies for inclusion, assessed risk of bias and carried out data extraction. Data entry was checked. Main results Fifteen studies (2750 women) were included, there were no studies on women over 13 weeks’ gestation. Studies addressed a number of comparisons and data are therefore limited. Three trials compared misoprostol treatment (all vaginally administered) with expectant care. There was no significant difference in complete miscarriage (average risk ratio (RR) 1.23, 95% confidence interval (CI) 0.72 to 2.10; two studies, 150 women), or in the need for surgical evacuation (average RR 0.62, 95% CI 0.17 to 2.26; two studies, 308 women). There were few data on ‘deaths or serious complications’. Nine studies involving 1766 women addressed the comparison of misoprostol (four oral, four vaginal, one vaginal + oral) with surgical evacuation. There was no statistically significant difference in complete miscarriage (average RR 0.96, 95% CI 0.92 to 1.00, eight studies, 1377 women) with success rate high for both methods

    The study aimed to assess the pharmacokinetics of a new, modified-release metoclopramide tablet, and compare it to an immediate-release tablet. A single and multiple-dose, randomized, open-label, parallel, pharmacokinetic study was conducted. Investigational products were administered to 26 healthy Hispanic Mexican male volunteers for two consecutive days: either one 30 mg modified-release tablet every 24 h, or one 10 mg immediate-release tablet every 8 h. Blood samples were collected after the first and last doses of metoclopramide. Plasma metoclopramide concentrations were determined by high-performance liquid chromatography. Safety and tolerability were assessed through vital signs measurements, clinical evaluations, and spontaneous reports from study subjects. All 26 subjects were included in the analyses [mean (SD) age: 27 (8) years, range 18-50; BMI: 23.65 (2.22) kg/m², range 18.01-27.47)]. Peak plasmatic concentrations were not statistically different with both formulations, but occurred significantly later (p < 0.05) with the modified-release form [tmax: 3.15 (1.28) vs. 0.85 (0.32) h and tmax-ss: 2.92 (1.19) vs. 1.04 (0.43) h]. There was no difference noted in the average plasma concentrations [Cavgτ: 23.90 (7.90) vs. 20.64 (7.43) ng/mL after the first dose; and Cavg-ss: 31.14 (9.64) vs. 35.59 (12.29) ng/mL after the last dose, (p > 0.05)]. One adverse event was reported in the test group (diarrhea), and one in the reference group (headache). This study suggests that the 30 mg modified-release metoclopramide tablets show features compatible with slow-release formulations when compared to immediate-release tablets, and is suitable for once-a-day administration.

    The aim of this Phase IIIb, open-label, randomized study was to demonstrate the non-inferiority of immune responses and to assess the safety of a purified chick-embryo cell rabies vaccine (PCECV) in healthy Chinese children (6 to 17 years) and older adults (≥51 years) following 2 alternative intramuscular (IM) simulated post-exposure prophylaxis (PEP) regimens: 4-dose Zagreb or 5-dose Essen regimen. Serum samples were collected prior to vaccination on Days 1 and 15 and on day 43 to assess immune response by rabies virus neutralizing antibody (RVNA) concentrations. Solicited adverse events (AEs) were recorded for up to 7 days following each vaccine dose, and unsolicited AEs throughout the entire study period. PCECV vaccination induced a strong immune response at Day 15, and the non-inferiority in immune response of the Zagreb vs. the Essen regimen was demonstrated in children and older adults. At Day 15,100% of children (N = 224), and 99% of subjects ≥51 years of age (N = 376) developed adequate RVNA concentrations (≥0.5 IU/mL); at Day 43 all subjects achieved RVNA concentrations ≥0.5 IU/mL, for both PEP regimens. The well-known tolerability and safety profile of the PCECV was again observed in this study following either Zagreb or Essen regimens. Rabies PEP vaccination with PCECV following a Zagreb regimen induced immune responses non-inferior to those of the Essen regimen, and had a similar safety and tolerability profile to the Essen regimen in Chinese children, adolescents, and adults over 51 years.

    This multicenter study assessed the safety and efficacy of teriparatide 20 microg/day in Japanese men and women with osteoporosis at high risk of fracture during a 12-month, randomized, double-blind, placebo-controlled treatment period followed by second and third treatment periods (to 18 and 24 months, respectively,) in which all subjects received open-label teriparatide. Subjects (93% female; median age 70 years) were randomized 2:1 to teriparatide versus placebo (randomized at baseline, teriparatide n=137, placebo-teriparatide n=70; entering the second period, teriparatide n=119, placebo-teriparatide n=59; entering the third period, teriparatide n=102, placebo-teriparatide n=50). For subjects with measurements at 12 months, teriparatide significantly increased bone mineral density (BMD) at the lumbar spine L2-L4 (mean percent change+/-SD, teriparatide 10.04+/-5.23% versus placebo-teriparatide 0.19+/-4.33%), the femoral neck (teriparatide 2.01+/-4.63% versus placebo-teriparatide 0.44+/-3.97%), and the total hip (teriparatide 2.72+/-4.04% versus placebo-teriparatide -0.26+/-3.42%). In the placebo-teriparatide group at 24 months (12-month teriparatide dosing) BMD increased by 9.11+/-5.14% at the lumbar spine, 2.19+/-4.81% at the femoral neck and 2.46+/-3.54% at the total hip. In the teriparatide group at 18 and 24 months, BMD increased from baseline at the lumbar spine by 11.93+/-5.79% and 13.42+/-6.12%, respectively; at the femoral neck by 2.68+/-4.45% and 3.26+/-4.25%, respectively; and at the total hip by 3.02+/-3.79% and 3.67+/-3.98%, respectively. Serum procollagen I N-terminal pro-peptide (PINP) increased rapidly with teriparatide treatment (P<0.001 versus placebo at 1 month) and changed from baseline in the teriparatide and placebo-teriparatide groups at 12 months by a median of 78.95% and -17.23%, respectively, (P<0.001) and at 24 months by 49.24% and 76.12%, respectively.

    ABSTRACT Prophylactic paracetamol administration impacts vaccine immune response; this study (www.clinicaltrials.gov: NCT01235949) is the first to assess PHiD-CV immunogenicity following prophylactic ibuprofen administration. In this phase IV, multicenter, open-label, randomized, controlled, non-inferiority study in Romania (November 2010–December 2012), healthy infants were randomized 3:3:3:1:1:1 to prophylactically receive immediate, delayed or no ibuprofen (IIBU, DIBU, NIBU) or paracetamol (IPARA, DPARA, NPARA) after each of 3 primary doses (PHiD-CV at age 3/4/5 months co-administered with DTPa-HBV-IPV/Hib at 3/5 and DTPa-IPV/Hib at 4 months) or booster dose (PHiD-CV and DTPa-HBV-IPV/Hib; 12–15 months). Non-inferiority of immune response one month post-primary vaccination in terms of percentage of infants with anti-pneumococcal antibody concentrations ≥0.2 µg/mL (primary objective) was demonstrated if the upper limit (UL) of the 98.25% confidence interval of difference between groups (NIBU vs IIBU, NIBU vs DIBU) was <10% for ≥7/10 serotypes. Immunogenicity and reactogenicity/safety were evaluated, including confirmatory analysis of difference in fever incidences post-primary vaccination in IBU or DIBU group compared to NIBU. Of 850 infants randomized, 812 were included in the total vaccinated cohort. Non-inferiority was demonstrated for both comparisons (UL was <10% for 9/10 vaccine serotypes; exceptions: 6B [NIBU], 23F [IIBU]). However, fever incidence post-primary vaccination in the IIBU and DIBU groups did not indicate a statistically significant reduction. Prophylactic administration (immediate or delayed) of paracetamol decreased fever incidence but seemed to reduce immune response to PHiD-CV, except when given only at booster. Twenty-seven serious adverse events were reported for 15 children; all resolved and were not vaccination-related. PMID:27541270

    Purpose To compare the bronchodilator efficacy of 18 μg once-daily tiotropium inhalation administered via Discair® versus HandiHaler® in adults with moderate-to-severe chronic obstructive pulmonary disease (COPD). Patients and methods Fifty-eight patients with moderate-to-severe COPD were enrolled in this randomized, active-controlled, parallel-group, open-label, Phase IV non-inferiority trial. Patients were randomly assigned to a test group (n=29, inhalation with Discair) or a reference group (n=29, inhalation with HandiHaler). The primary efficacy parameter was the average maximum change in forced expiratory volume in 1 second (FEV1, in L). Change in forced vital capacity (FVC, in L), %FEV1 and %FVC, the standardized area under the response–time curve (AUC) for the absolute change in FEV1 and FVC, time to onset and peak of response, and safety data were also evaluated. Results The test inhaler was non-inferior to the reference inhaler in terms of maximum change in FEV1 at 24 h (unadjusted change: 0.0017 L [95% confidence interval [CI]: −0.0777, 0.0812]; change adjusted for time to reach maximum change in FEV1 and smoking in pack-years: 0.0116 L [95% CI: −0.0699, 0.0931]), based on a non-inferiority margin of 0.100 L. There were also no significant differences between the two groups in maximum change in FVC value from baseline (0.3417 L vs 0.4438 L, P=0.113), percent change from baseline (22.235 vs 20.783 for FEV1, P=0.662; 16.719 vs 20.337 for FVC, P=0.257), and AUC0–24 h (2.949 vs 2.833 L for FEV1, P=0.891; 2.897 vs 4.729 L for FVC, P=0.178). There were no adverse events, serious adverse events, or deaths. Conclusion Our findings show that the Discair was non-inferior to the HandiHaler. More specifically, these devices had similar clinical efficacy in terms of time-dependent response over 24 h for patients with moderate-to-severe COPD. PMID:27920513

    2013-01-01

    Background Prospective efficacy monitoring of anti-malarial treatments is imperative for timely detection of resistance development. The in vivo efficacy of artesunate-amodiaquine (ASAQ) fixed-dose combination (FDC) was compared to that of artemether-lumefantrine (AL) among children aged six to 59 months in Nimba County, Liberia, where Plasmodium falciparum malaria is endemic and efficacy data are scarce. Methods An open-label, randomized controlled non-inferiority trial compared the genotyping adjusted day 42 cure rates of ASAQ FDC (ASAQ Winthrop®) to AL (Coartem®) in 300 children aged six to 59 months with uncomplicated falciparum malaria. Inclusion was between December 2008 and May 2009. Randomization (1:1) was to a three-day observed oral regimen (ASAQ: once a day; AL: twice a day, given with fatty food). Day 7 desethylamodiaquine and lumefantrine blood-concentrations were also measured. Results The day 42 genotyping-adjusted cure rate estimates were 97.3% [95% CI: 91.6-99.1] for ASAQ and 94.2% [88.1-97.2] for AL (Kaplan-Meier survival estimates). The difference in day 42 cure rates was −3.1% [upper limit 95% CI: 1.2%]. These results were confirmed by observed proportion of patients cured at day 42 on the per-protocol population. Parasite clearance was 100% (ASAQ) and 99.3% (AL) on day 3. The probability to remain free of re-infection was 0.55 [95% CI: 0.46-0.63] (ASAQ) and 0.66 [0.57-0.73] (AL) (p = 0.017). Conclusions Both ASAQ and AL were highly efficacious and ASAQ was non-inferior to AL. The proportion of patients with re-infection was high in both arms in this highly endemic setting. In 2010, ASAQ FDC was adopted as the first-line national treatment in Liberia. Continuous efficacy monitoring is recommended. Trial registration The protocols were registered with Current Controlled Trials, under the identifier numbers ISRCTN51688713, ISRCTN40020296. PMID:23866774

    In this open label study, 75 patients with a diagnosis of schizophrenia were randomized to three groups of 25 each, receiving 150mg/day ranitidine, 300mg/day ranitidine and receiving only olanzapine. They were rated on PANSS at baseline, 4 and 8 weeks. There was a significant reduction in the scores of negative scale in patients receiving 300mg/day ranitidine in comparison to patients not receiving ranitidine at the end of 4 weeks but was not seen again when assessed at the end of 8 weeks. Though effective in reducing the negative symptoms, the effect was not sustained due to the tolerance to the actions of ranitidine.

    [Purpose] The aim of this study was to examine the effect of resistance exercise on carotid intima-media thickness, luminal diameter, peak systolic flow velocity, end diastolic flow velocity, and wall shear rate in healthy elderly men. [Subjects and Methods] Thirty healthy elderly men (age ≥65 years) were randomly divided into a control (n=15) and resistance exercise (n=15) groups. The 24-week exercise intervention consisted of 3 days of resistance exercise per week using an elastic band per week. Body composition, physical function, blood pressure, and carotid variables were measured at baseline and after 24 weeks. [Results] Body fat percent, skeletal muscle mass, systolic blood pressure, grip strength, arm curl, chair stand up, sit and reach, maximum walking speed, time up and go, and two-minute step test showed significant interaction. Peak systolic flow velocity, end diastolic flow velocity, and wall shear rate also showed significant interaction. [Conclusion] A 24-week resistance exercise program, using elastic bands, effectively improves carotid flow velocity and wall shear rate in healthy elderly men. PMID:27821937

    Aims To evaluate the efficacy and safety of extended dosing with mipomersen in patients with familial hypercholesterolaemia (HC) taking maximally tolerated lipid-lowering therapy. Methods and results A planned interim analysis of an ongoing, open-label extension trial in patients (n = 141) with familial HC receiving a subcutaneous injection of 200 mg mipomersen weekly plus maximally tolerated lipid-lowering therapy for up to 104 weeks. The mean changes in low-density lipoprotein cholesterol (LDL-C) from baseline to weeks 26 (n = 130), 52 (n = 111), 76 (n = 66), and 104 (n = 53) were −28, −27, −27, and −28%; and in apolipoprotein B −29, −28, −30, and −31%, respectively. Reductions in total cholesterol, non-high-density lipoprotein-cholesterol, and lipoprotein(a) were comparable with decreases in LDL-C and apolipoprotein B levels. Mean high-density lipoprotein cholesterol increased from baseline by 7 and 6% at weeks 26 and 52, respectively. The long-term safety profile of mipomersen was similar to that reported in the associated randomized placebo-controlled Phase 3 trials. Adverse events included injection site reactions and flu-like symptoms. There was an incremental increase in the median liver fat during the initial 6–12 months that appeared to diminish with continued mipomersen exposure beyond 1 year and returned towards baseline 24 weeks after last drug dose suggestive of adaptation. The median alanine aminotransferase level showed a similar trend over time. Conclusion Long-term treatment with mipomersen for up to 104 weeks provided sustained reductions in all atherosclerotic lipoproteins measured and a safety profile consistent with prior controlled trials in these high-risk patient populations.

    This study examined the effects of 24 weeks of Tai Chi Quan on the postural control of elderly women. A total of 43 women aged 55-68 years participated in the study. A Tai Chi group (n = 22) underwent an organized Tai Chi exercise, whereas the control group (n = 21) maintained a habitual, no-regular-exercise lifestyle. A Good Balance tester (Metitur, Finland) was used to measure the time, paths and velocity of the center of pressure (COP) of subjects during stance while shifting COP to targeted positions shown on a monitor. After 24 weeks, the Tai Chi group showed significantly shorter total (18.6%, p = 0.005), mediolateral (21.9%, p = 0.002) and anteroposterior (18.3%, p = 0.002) COP sway paths than the control group. The results indicate that 24 weeks of the Tai Chi exercise improved the efficiency of postural control for elderly women.

    Background T-type calcium channel activation has been postulated to underlie rhythmicity in the olivo-cerebellar system that is implicated in ET. Ethosuximide reduces T-type calcium currents and can suppress tremor in two animal models of ET. We explored the effects of ethosuximide in subjects with ET in an open-label trial using both clinical scales and accelerometric recordings measures. We initially planned to conduct the trial with 15 patients, but due to lack of efficacy and a high incidence of adverse effects, the trial was stopped after seven patients had participated. Methods Seven patients diagnosed with ET were included in the study. The ethosuximide dose was 500 mg daily (BID). The main outcome measures were: 1) tremor clinical rating scale (TCRS) score, 2) accelerometric recordings, and 3) self-reported disability scale score. Results Five patients completed the study, and two dropped out due to adverse effects. There were no significant changes in clinical scores in motor task performance (TCRS 1+2), daily living activities (TCRS 3), or in the patients’ subjective assessment (TCRS 4) and global appraisal. There were no differences observed for accelerometry data or disability scale scores. Anxiety, nervousness, headache, and dizziness were reported by two patients while on ethosuximide, causing them to stop the trial. No patient preferred to continue ethosuximide treatment. Discussion The results of our exploratory study suggest that ethosuximide is not an effective treatment for ET. PMID:27625899

    Previous studies tested the efficacy of sertraline in Binge Eating Disorder (BED) over a period of 6 weeks. The present open study assesses the efficacy of sertraline over a period of 24 weeks in obese persons with binge eating behaviour (with or without the full criteria for BED) confirmed by high scores on the Binge Eating Scale (BES). Thirty-two obese outpatients (14 with BED and 18 without full criteria for BED), without co-occurring psychiatric comorbidities, were treated with sertraline (dose range 100-200 mg/d). Subjects were assessed at baseline and at 8, 12 and 24 weeks of treatment for number of binges, weight and psychopathology. After 8 weeks of treatment a significant improvement in the BES score and a significant weight loss emerged. These results were maintained over 24 weeks. A moderate drop out rate was detected, but no significant association with the severity of side effects was found. Further studies are needed to confirm the usefulness of sertraline in the treatment of patients with BED and also in binge eaters with a less severe eating psychopathology.

    Objective: To evaluate the effectiveness of a novel oral supplement, Forti5®, containing green tea extract, omega 3 and 6 fatty acids, cholecalciferol, melatonin, beta-sitosterol, and soy isoflavones, and in the management of subjects with androgenetic alopecia. Design: A prospective case series of 10 subjects. Setting: Open-label, evaluator-blinded, proof-of-concept study. Participants: Ten adult subjects with androgenetic alopecia completed the study. Subjects were not allowed to use oral or topical hair growth products in the 24 weeks preceding the study or during the study. The nutritional supplement was administered at a dosage of two tablets daily for 24 weeks. Measurements: Clinical evaluations were performed at baseline and at 24 weeks. Efficacy was evaluated using hair mass index measured by cross section trichometer, terminal hair count measured with dermoscopy and Investigator Global Photography Assessment. Results: Overall 80 percent of subjects (8/10) were rated as improved after 24 weeks of supplementation (mean change of +1.4 equivalent to slightly-to-moderately increased). Forty percent of subjects (4/10) were rated as moderately improved (2+), and 10 percent (1/10) were rated as greatly improved (3+). There was a significant improvement in terminal hair count (mean increase of 5.9% or 4.2 more terminal hairs in the area examined, p=0.014) and in Hair Mass Index (mean increase of 9.5% or 4.5 higher Hair Mass Index, p=0.003). Conclusion: These preliminary results indicate that Forti5® a novel nutritional supplement that contains cholecalciferol, omega 3 and 6 fatty acids, melatonin, antioxidants, and botanical 5-alpha reductase inhibitors, may be a useful adjunct in the treatment of androgenetic alopecia.

    Background. Human immunodeficiency virus (HIV)–infected individuals are at increased risk of cardiovascular disease (CVD) due in part to inflammation. Statins decrease inflammation in the general population, but their effect during HIV infection is largely unknown. Methods. This is an ongoing randomized, double-blinded, placebo-controlled trial to evaluate the effect of statin therapy on inflammatory markers during HIV infection. Subjects received rosuvastatin 10 mg daily or placebo for 24 weeks. Subjects were receiving stable (>12 weeks) antiretroviral therapy and had a low-density lipoprotein (LDL) cholesterol level of ≤130 mg/dL and evidence of heightened immune activation or inflammation. This was a prespecified interim analysis. Results. A total of 147 subjects were enrolled (78% were male, 70% were black, and the median age was 47 years). By 24 weeks, LDL cholesterol levels had decreased in the statin group, compared with an increase in the placebo group (−28% vs +3.8%; P < .01). A 10% reduction in the lipoprotein-associated phospholipase A2 (Lp-PLA2) level was seen in the statin group, compared with a 2% reduction in the placebo group (P < .01). In multivariable regression, receipt of statin treatment and having a nadir CD4+ T-cell count of ≤100 cell/µL were the only statistically significant predictors of a decrease in Lp-PLA2 level. Markers of systemic inflammation did not change significantly between groups. Conclusions. Twenty-four weeks of rosuvastatin therapy significantly decreased the level of Lp-PLA2, a vascular-specific, inflammatory enzyme that predicts cardiovascular events in the general population. Statins may hold promise as a means of attenuating CVD risk in HIV-infected individuals by decreasing Lp-PLA2 levels. PMID:24415784

    Systemic fungal infection continues to be a major cause of mortality in extremely low-birth-weight premature infants. Amphotericin B has been recommended as the primary treatment; however, its use is limited due to drug-induced nephrotoxicity and amphotericin B-resistant candidemia. Caspofungin therapy was initiated in seven extremely premature infants at 23 and 24 weeks' gestation with persistent systemic candidiasis despite liposomal amphotericin B treatment. The gestational age was 23(+1)-24(+6) weeks, and birth weight was 530-825 g. Of the seven patients, the peripheral blood cultures of six patients were positive for Candida parapsilosis and one had positive culture for Candida albicans. The dosage of caspofungin was 2 mg/kg/day, and the mean treatment duration was 14 days. All of the persistent candidemia resolved on caspofungin therapy. There was no recurrent candidemia after discontinuing caspofungin. There were no adverse effects, hepatotoxicity, nephrotoxicity, anemia, or thrombocytopenia. Caspofungin successfully treated persistent candidemia in extremely premature infants at 23 and 24 weeks' gestational age.

    Background. Studies using standard neuropsychological instruments have demonstrated memory deficits in patients with PTSD. We evaluated the efficacy and safety of the N-methyl-D-aspartate antagonist memantine in veterans with PTSD and cognitive impairment. Methods. Twenty-six veterans with PTSD and cognitive impairment received 16 weeks of memantine in an open-label fashion. Cognition was assessed using the Spatial Span, Logical Memory I, and Letter-Number Sequencing subtests of the Wechsler Memory Scale III and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). RBANS measures attention, language, visuospatial skills, and immediate and delayed memories. The Clinician Administered PTSD Scale (CAPS), Hamilton Depression Scale (HAM-D), Hamilton Anxiety Scale (HAM-A), Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), and Sheehan Disability Scale (SDS) were secondary outcome measures. Results. There was a significant improvement in RBANS, both total and subscale scores (P < 0.05), over time. There was a reduction in total CAPS scores, avoidance/numbing symptoms (CAPS-C) and hyperarousal symptoms (CAPS-D), HAM-D, Q-LES-Q, and SDS scores. However, there was no reduction in reexperiencing (CAPS-B) and HAM-A scores. Memantine was well tolerated. Conclusions. Memantine improved cognitive symptoms, PTSD symptoms, and mood in veterans with PTSD. Randomized double-blind studies are needed to validate these preliminary observations. PMID:26064685

    Eryngium foetidum Linn. leaves (EF) are widely used in Thailand and many countries throughout Asia as a culinary seasoning and a traditional medicine. However, adverse effect of high dose consumption in long duration has not been evaluated. The aim of this study was to investigate chronic toxicity of EF in mice. Thirty-two ICR male mice were divided into 4 groups of 8 mice each. The mice were fed AIN-76 rodent diet, or AIN-76 rodent diet supplemented with ground freeze-dried EF at 0.8%, 1.6% and 3.2% that is equivalent to approximately 35, 73 and 155 times that of human consumption, respectively, at 97.5 percentile for a period of 24 weeks. At the end of experiment, the mice were euthanized and blood samples were collected for hematological and biochemical evaluations. Necropsy was performed while visceral organs such as lung, liver, kidneys, spleen etc. were collected, weighed and histopathologically examined. Blood urea nitrogen (BUN) results of mice in 1.6% and 3.2% EF diet groups were significantly higher than the BUN of control group. No significant difference was noted in other biochemical and hematological properties between the treatment groups and control; all results were within normal range. Histopathology of almost all visceral organs showed no significant changes. However, tubulonephrosis and chronic interstitial nephritis were observed in the groups treated with 1.6% and 3.2% EF diet. Body weight was reduced significantly at week 12 to week 20 when compared to the control group while relative kidney weights were significantly increased. In conclusion, the consumption of EF in diet at high doses illustrated the adverse effect on some biochemical parameters and histopathology in mice. Our findings suggested that EF daily consumption for 24 weeks, at higher doses than the 0.8% EF diet (35 times of human consumption), might cause adverse effect on kidney function in mice.

    In the CLARINET study, lanreotide Autogel (depot in USA) significantly prolonged progression-free survival (PFS) in patients with metastatic pancreatic/intestinal neuroendocrine tumours (NETs). We report long-term safety and additional efficacy data from the open-label extension (OLE). Patients with metastatic grade 1/2 (Ki-67 ≤10%) non-functioning NET and documented baseline tumour-progression status received lanreotide Autogel 120 mg (n=101) or placebo (n=103) for 96 weeks or until death/progressive disease (PD) in CLARINET study. Patients with stable disease (SD) at core study end (lanreotide/placebo) or PD (placebo only) continued or switched to lanreotide in the OLE. In total, 88 patients (previously: lanreotide, n=41; placebo, n=47) participated: 38% had pancreatic, 39% midgut and 23% other/unknown primary tumours. Patients continuing lanreotide reported fewer adverse events (AEs) (all and treatment-related) during OLE than core study. Placebo-to-lanreotide switch patients reported similar AE rates in OLE and core studies, except more diarrhoea was considered treatment-related in OLE (overall diarrhoea unchanged). Median lanreotide PFS (core study randomisation to PD in core/OLE; n=101) was 32.8 months (95% CI: 30.9, 68.0). A sensitivity analysis, addressing potential selection bias by assuming that patients with SD on lanreotide in the core study and not entering the OLE (n=13) had PD 24 weeks after last core assessment, found median PFS remaining consistent: 30.8 months (95% CI: 30.0, 31.3). Median time to further PD after placebo-to-lanreotide switch (n=32) was 14.0 months (10.1; not reached). This OLE study suggests long-term treatment with lanreotide Autogel 120 mg maintained favourable safety/tolerability. CLARINET OLE data also provide new evidence of lanreotide anti-tumour benefits in indolent and progressive pancreatic/intestinal NETs. PMID:26743120

    Thirty-four individuals with mild cognitive impairment were randomized for 6 months to a nutraceutical formulation (NF: folate, alpha-tocopherol, B12, S-adenosyl methioinine, N-acetyl cysteine, acetyl-L-carnitine) or indistinguishable placebo, followed by a 6-month open-label extension in which all individuals received NF. The NF cohort improved in the Dementia Rating Scale (DRS; effect size >0.7) and maintained baseline performance in CLOX-1. The placebo cohort did not improve in DRS and declined in CLOX-1, but during the open-label extension improved in DRS and ceased declining in CLOX-1. These findings extend prior studies of NF efficacy for individuals without cognitive impairment and with Alzheimer's disease.

    The purpose of the present study was to evaluate the influence of a mixed exercise program, including Greek traditional dances and upper body training, in physical function, strength and psychological condition of breast cancer survivors. Twenty-seven women (N = 27), who had been diagnosed and surgically treated for breast cancer, volunteered to participate in this study. The experimental group consisted of 14 women with mean age 56.6 (4.2) years. They attended supervised Greek traditional dance courses and upper body training (1 h, 3 sessions/week) for 24 weeks. The control group consisted of 13 sedentary women with mean age 57.1 (4.1) years. Blood pressure, heart rate, physical function (6-min walking test), handgrip strength, arm volume and psychological condition (Life Satisfaction Inventory and Beck Depression Inventory) were evaluated before and after the exercise program. The results showed significant increases of 19.9% for physical function, 24.3% for right handgrip strength, 26.1% for left handgrip strength, 36.3% for life satisfaction and also a decrease of 35% for depressive symptoms in the experimental group after the training program. Significant reductions of 9% for left hand and 13.7% for right hand arm volume were also found in the experimental group. Consequently, aerobic exercise with Greek traditional dances and upper body training could be an alternative choice of physical activity for breast cancer survivors, thus promoting benefits in physical function, strength and psychological condition.

    Abstract Objective The purpose of this study was to report the safety, tolerability, and serum micronutrient concentrations and their correlations with mood changes from an 8 week pilot feasibility study of a 36 ingredient multinutrient supplement, EMPowerplus (EMP+), for pediatric bipolar spectrum disorders (BPSD). Methods Ten children ages 6–12 received EMP+ escalating from one to four capsules t.i.d., with four children increased to the maximum suggested dose, five capsules t.i.d. Outcome measures were micronutrient concentrations in serum and red blood cells, vital signs, body mass index (BMI), dietary intake (Food Frequency Questionnaire and 24 hour dietary recall interview), and mood and global functioning ratings. Results Seven children (70%) completed the study. Three (30%) terminated early for tolerability and compliance issues. Adverse effects were mild and transient, and chiefly consisted of initial insomnia or gastrointestinal (GI) upset. No differences occurred in BMI (p=0.310) or waist–hip ratio (WHR; p=0.674) pre- to postsupplementation. Four of the tested serum vitamin concentrations increased from pre- to postsupplementation: vitamin A-retinol, vitamin B6, vitamin E-α-tocopherol; and folate (all p<0.05). The increase in serum 25-OH vitamin D approached significance (p=0.063). No differences were found in dietary intake pre- to postsupplementation, suggesting that blood nutrient level increases were caused by EMP+. Conclusions In this open prospective study, short-term use of EMP+ in children with BPSD appeared safe and well-tolerated, with a side effect profile preferable to first-line psychotropic drugs for pediatric bipolar spectrum disorders. A double-blind, randomized clinical trial is feasible, appears safe, and is warranted by open-label clinical outcomes and plausible mechanisms of action, combined with documentation of increased serum concentrations of specific micronutrients.

    Summary Background Standard-of-care antiretroviral therapy (ART) uses a combination of drugs deemed essential to minimise treatment failure and drug resistance. Protease inhibitors are potent, with a high genetic barrier to resistance, and have potential use as monotherapy after viral load suppression is achieved with combination treatment. We aimed to assess clinical risks and benefits of protease inhibitor monotherapy in long-term clinical use: in particular, the effect on drug resistance and future treatment options. Methods In this pragmatic, parallel-group, randomised, controlled, open-label, non-inferiority trial, we enrolled adults (≥18 years of age) positive for HIV attending 43 public sector treatment centres in the UK who had suppressed viral load (<50 copies per mL) for at least 24 weeks on combination ART with no change in the previous 12 weeks and a CD4 count of more than 100 cells per μL. Participants were randomly allocated (1:1) to maintain ongoing triple therapy (OT) or to switch to a strategy of physician-selected ritonavir-boosted protease inhibitor monotherapy (PI-mono); we recommended ritonavir (100 mg)-boosted darunavir (800 mg) once daily or ritonavir (100 mg)-boosted lopinavir (400 mg) twice daily, with prompt return to combination treatment if viral load rebounded. All treatments were oral. Randomisation was with permuted blocks of varying size and stratified by centre and baseline ART; we used a computer-generated, sequentially numbered randomisation list. The primary outcome was loss of future drug options, defined as new intermediate-level or high-level resistance to one or more drugs to which the patient's virus was deemed sensitive at trial entry (assessed at 3 years; non-inferiority margin of 10%). We estimated probability of rebound and resistance with Kaplan-Meier analysis. Analyses were by intention to treat. This trial is registered with the International Standard Randomised Controlled Trial Number registry, number ISRCTN

    The quality and safety parameters of mixed marinated seafood salad containing common octopus (Octopus vulgaris), shrimp (Parapenaeus longirostris), European squid (Loligo vulgaris), sea snail (Rapana thomasiana) and common cuttlefish (Sepia officinalis) at 4 degrees C during storage of 24 weeks were investigated. In addition, the nutritional value in terms of proximate and fatty acid composition of seafood salad was also determined. Sensory scores of seafood salad in terms of appearance, odour, flavour and texture slightly decreased throughout the storage period. However, at the end of the storage period (5 months), the marinated seafood salad was still acceptable by the panellist. At the beginning of storage the total volatile basic nitrogen (TVB-N) value was 6.05 mg/100 g flesh, and the TVB-N values rose to 11.19 mg TVB-N/flesh by the end of the storage period. The pH value of the marinated seafood salad showed fluctuations, ranging from 3.57 to 3.65, and did not change significantly during the storage period. The concentrations of the biogenic amines in both the muscle of all species and in the solution of salad were also investigated. Among the biogenic amines, histamine was not detected in all samples throughout the storage period. The putrescine and cadaverine levels increased throughout the storage period, with a lower increase in the solution of seafood salad. Salmonella, coliform, Escherichia coli and Staphylococcus aureus were not detected while the total viable count remained low (3 log CFU/g) after 3 months of storage.

    Abstract Objective The purpose of this open-label pilot study was to investigate the effectiveness and tolerability of guanfacine extended release (GXR) 1–4 mg given in the evening, on the symptoms of traumatic stress (reexperiencing, avoidance, overarousal), generalized anxiety, and functional impairment in children and adolescents with a history of traumatic stress with or without posttraumatic stress disorder (PTSD). As many of our sample had associated attention-deficit/hyperactivity disorder (ADHD) symptoms, we also assessed whether the presence of traumatic stress symptoms impaired the effectiveness of GXR in the treatment of comorbid ADHD symptoms. Methods Participants were 19 children and adolescents 6–18 years of age, with current traumatic stress symptoms. In an 8 week open-label design, each patient's scores on parent-, child-, and clinician-reported symptom rating scales assessing traumatic stress symptoms, generalized anxiety, ADHD symptoms, functional impairment, and global symptom severity and improvement (n=17) were evaluated off and on GXR using χ2 goodness-of-fit tests, paired t tests, and repeated measures analyses of variance (ANOVAs). To examine patterns of change in outcome measures across treatment, MPlus software was used to conduct linear growth curves modeled with individual-varying times of observation (i.e., random slopes). Results Using an average GXR daily dose of 1.19 mg±0.35 mg and an average weight-adjusted daily dose of 0.03 mg/kg±0.01 mg/kg, significant differences were found on all symptom severity measures. Parent reported UCLA Reaction Index scores assessing cluster B (reexperiencing), C (avoidant), and D (overarousal) symptoms significantly improved. In the presence of PTSD symptoms, children with ADHD experienced significantly improved ADHD symptom scores, suggesting that comorbidity does not attenuate an ADHD symptom response to GXR therapy. Medication was generally well tolerated. Conclusions Within the

    Abstract Objectives: This open-label, prospective, phase I/II trial was performed to establish the safety and efficacy of Traditional Chinese Medicine (TCM) herbal products for treating non–anemia-related fatigue in patients with cancer. Although this practice is widespread in China, it has not been confirmed in a prospective clinical study. Design: Thirty-three patients who had completed cancer treatment, had stable disease and no anemia, and reported moderate to severe fatigue (rated ≥4 on a 0–10 scale) were enrolled in a TCM outpatient clinic. Patients took Ren Shen Yangrong Tang (RSYRT) decoction, a soup containing 12 TCM herbs, twice a day for 6 weeks. RSYRT aims to correct qi deficiency. Fatigue was assessed before and after RSYRT therapy, which all patients completed. Results: No discomfort or toxicity was observed. Before the study, all patients had had fatigue for at least 4 months. Fatigue severity decreased significantly from before therapy to 6 weeks after therapy: from 7.06 to 3.30 on a 0–10 scale (p<0.001). Fatigue category (mild, moderate, severe) shifted significantly (p=0.024): Of 22 patients with severe fatigue (rated ≥7) before therapy, 11 had mild fatigue and 11 had moderate fatigue after TCM treatment. The time-to-fatigue-alleviation was 2–3 weeks. Conclusion: RSYRT therapy was safe and was associated with fatigue improvement in nonanemic cancer survivors, consistent with historical TCM clinical practice experience. Because of a possible placebo effect in this open-label study, decoction RSYRT warrants further study in randomized clinical trials to confirm its effectiveness for managing moderate to severe fatigue.

    Hereditary angioedema (HAE) is characterized by potentially life-threatening recurrent episodes of oedema. The open-label extension (OLE) phase of the For Angioedema Subcutaneous Treatment (FAST)-1 trial (NCT00097695) evaluated the efficacy and safety of repeated icatibant exposure in adults with multiple HAE attacks. Following completion of the randomized, controlled phase, patients could receive open-label icatibant (30 mg subcutaneously) for subsequent attacks. The primary end-point was time to onset of primary symptom relief, as assessed by visual analogue scale (VAS). Descriptive statistics were reported for cutaneous/abdominal attacks 1–10 treated in the OLE phase and individual laryngeal attacks. Post-hoc analyses were conducted in patients with ≥ 5 attacks across the controlled and OLE phases. Safety was evaluated throughout. During the OLE phase, 72 patients received icatibant for 340 attacks. For cutaneous/abdominal attacks 1–10, the median time to onset of primary symptom relief was 1·0–2·0 h. For laryngeal attacks 1–12, patient-assessed median time to initial symptom improvement was 0·3–1·2 h. Post-hoc analyses showed the time to onset of symptom relief based on composite VAS was consistent across repeated treatments with icatibant. One injection of icatibant was sufficient to treat 88·2% of attacks; rescue medication was required in 5·3% of attacks. No icatibant-related serious adverse events were reported. Icatibant provided consistent efficacy and was well tolerated for repeated treatment of HAE attacks. PMID:24749847

    The current data suggest that up to 50% of patients with schizophrenia have obsessive-compulsive (OC) symptoms coexisting with psychosis and between 7.8 and 46% of schizophrenia patients also have full-blown obsessive-compulsive disorder (OCD). The aim of this study was to examine the efficacy of the most selective serotonin reuptake inhibitor escitalopram in the management of OCD in schizophrenia patients. The study was an open-label prospective trial of 12 weeks' duration in which escitalopram at a dose of up to 20 mg/day was added to the existing antipsychotic drug regimen in schizophrenia patients with OCD. Fifteen patients (10 men/five women) with the diagnosis of schizophrenia and OCD were recruited for the study (mean age: 39±14, range 21-61 years) and received escitalopram according to the study design. A significant improvement was observed in the total Yale Brown Obsessive-Compulsive Scale (Y-BOCS) scores and in the scores of both the Y-BOCS-Obsession and the Y-BOCS-Compulsion subscale at the end point. In addition, a significant improvement was observed in the total scores of the Positive and Negative Syndrome Scale and particularly in scores of anxiety, tension, depression, and preoccupation items. No adverse effects of escitalopram were reported by patients during the trial. In our prospective 12-week open-label study, escitalopram 20 mg/day was well tolerated and improved OC symptoms in schizophrenia patients. Our preliminary results are encouraging and a double-blind randomized study is required to confirm our results.

  1. A randomized, open-label, multicenter, phase II study evaluating the efficacy and safety of BTH1677 (1,3-1,6 beta glucan; Imprime PGG) in combination with cetuximab and chemotherapy in patients with advanced non-small cell lung cancer.

    Introduction BTH1677, a 1,3-1,6 beta-glucan immunomodulator, stimulates a coordinated anti-cancer immune response in combination with anti-tumor antibody therapies. This phase II study explored the efficacy, pharmacokinetics (PK), and safety of BTH1677 combined with cetuximab/carboplatin/paclitaxel in untreated stage IIIB/IV non-small cell lung cancer (NSCLC) patients. Methods Patients were randomized 2:1 to the BTH1677 arm (N=60; BTH1677, 4 mg/kg, weekly; cetuximab, initial dose 400 mg/m(2) and subsequent doses 250 mg/m(2), weekly; carboplatin, 6 mg/mL/min AUC (area-under-the-curve) by Calvert formula, once each 3-week cycle [Q3W]); and paclitaxel, 200 mg/m(2), Q3W) or Control arm (N=30; cetuximab/carboplatin/paclitaxel as above). Carboplatin/paclitaxel was discontinued after 4-6 cycles; patients who responded or remained stable received maintenance therapy with BTH1677/cetuximab (BTH1677 arm) or cetuximab (Control arm). Investigator and blinded central radiology reviews were conducted. Efficacy assessments included objective response rate (ORR; primary endpoint), disease control rate, duration of objective response, time-to-progression and overall survival (OS); safety was assessed by adverse events (AEs). Potential biomarker analysis for BTH1677 response was also conducted. Results Compared to control treatment, the addition of BTH1677 numerically increased ORR by both investigator (47.8% vs 23.1%; p=0.0468) and central (36.6% vs 23.1%; p=0.2895) reviews. No other endpoints differed between arms. PK was consistent with previous studies. BTH1677 was well tolerated, with AEs expected of the backbone therapy predominating. Biomarker-positive patients displayed better ORR and OS than negative patients. Conclusions BTH1677 combined with cetuximab/carboplatin/paclitaxel was well tolerated and improved ORR as first-line treatment in patients with advanced NSCLC. Future patient selection by biomarker status may further improve efficacy ClinicalTrials.gov Identifier: NCT

    Objective This study aimed to identify possible improvements in disease-specific health-related quality of life (HRQoL) after multiple injections of botulinum toxin A over 24 weeks in Thai cervical dystonia (CD) patients. Materials and methods A 24-week prospective study comparing HRQoL of Thai CD patients before and after multiple injections of botulinum toxin A at 3-month intervals was performed. Disease-specific HRQoL was assessed by using the Cervical Dystonia Impact Profile-58 questionnaire (CDIP-58) and the Craniocervical Dystonia Questionnaire-24 (CDQ-24). General HRQoL was assessed by using the Medical Outcomes’ 36-Item Short Form Health Survey (SF-36) and the EuroQoL 5-dimension questionnaire (EQ-5D). All the assessments were performed before and after the 24-week treatment period. Results A total of 20 CD patients were enrolled in this study from April to December 2011. CDIP-58 and CDQ-24 scores, which assess disease-specific HRQoL, showed a significant improvement after 24 weeks of treatment by botulinum toxin A (P<0.001). However, EQ-5D and SF-36 scores, which assess general HRQoL, showed no significant improvement after the treatment (P>0.05). Conclusion CD patients’ disease-specific HRQoL improved after being treated with multiple botulinum toxin A injections. However, general HRQoL was not improved. PMID:28138245

    Summary Background We aimed to investigate whether gatifloxacin, a new generation and affordable fluoroquinolone, is better than chloramphenicol for the treatment of uncomplicated enteric fever in children and adults. Methods We did an open-label randomised superiority trial at Patan Hospital, Kathmandu, Nepal, to investigate whether gatifloxacin is more effective than chloramphenicol for treating uncomplicated enteric fever. Children and adults clinically diagnosed with enteric fever received either gatifloxacin (10 mg/kg) once a day for 7 days, or chloramphenicol (75 mg/kg per day) in four divided doses for 14 days. Patients were randomly allocated treatment (1:1) in blocks of 50, without stratification. Allocations were placed in sealed envelopes opened by the study physician once a patient was enrolled into the trial. Masking was not possible because of the different formulations and ways of giving the two drugs. The primary outcome measure was treatment failure, which consisted of at least one of the following: persistent fever at day 10, need for rescue treatment, microbiological failure, relapse until day 31, and enteric-fever-related complications. The primary outcome was assessed in all patients randomly allocated treatment and reported separately for culture-positive patients and for all patients. Secondary outcome measures were fever clearance time, late relapse, and faecal carriage. The trial is registered on controlled-trials.com, number ISRCTN 53258327. Findings 844 patients with a median age of 16 (IQR 9–22) years were enrolled in the trial and randomly allocated a treatment. 352 patients had blood-culture-confirmed enteric fever: 175 were treated with chloramphenicol and 177 with gatifloxacin. 14 patients had treatment failure in the chloramphenicol group, compared with 12 in the gatifloxacin group (hazard ratio [HR] of time to failure 0·86, 95% CI 0·40–1·86, p=0·70). The median time to fever clearance was 3·95 days (95% CI 3·68–4·68

    Abstract Lipohypertrophy in HIV-infected patients is associated with metabolic abnormalities. Raltegravir (RAL) is not known to induce fat changes or severe metabolic perturbations. HIV-infected women with central adiposity and HIV-1 RNA less than 50 copies per milliliter on non-nucleoside reverse transcriptase inhibitor (NNRTI)- or protease inhibitor (PI)-based antiretroviral therapy (ART) continued their nucleoside reverse transcriptase inhibitor (NRTI) backbone and were randomized to switch to open label RAL immediately or after 24 weeks. The primary end point was 24-week between-group change in computed tomography (CT)-quantified visceral adipose tissue (AT) volume. Fasting lipids, glucose, C-reactive protein (CRP), anthropometric measurements, and patient-reported quality of life assessments were also measured. Thirty-six subjects provided 80% power to detect a 10% between-group difference in visceral AT over 24 weeks. Thirty-seven of 39 enrolled subjects completed week 24. At entry, subjects were 75% black or Hispanic, and on 62% PI-based and 38% NNRTI-based regimens. The median age was 43 years, CD4 count 558 cells per microliter, and body mass index (BMI) 32 kg/m2. After 24 weeks, no statistically significant changes in visceral or subcutaneous AT, anthropometrics, BMI, glucose, or CRP were observed. In subjects receiving RAL, significant improvements in total and LDL cholesterol (p=0.04), self-reported belly size (p=0.02) and composite body size (p=0.02) were observed. Body size changes correlated well with percent visceral AT change. No RAL-related adverse events occurred. Compared to continued PI or NNRTI, switch to RAL was associated with statistically significant 24-week improvements in total and LDL cholesterol but not AT volumes. Additional insights into AT and metabolic changes in women on RAL will be provided by 48-week follow-up of the immediate-switch arm. PMID:22823027

    We investigated time-related predictors of death or neurological sequelae in extremely preterm infants (EPI) born at 22 to 24 weeks' gestation by categorizing clinical patterns according to their survival time and morbidity. Data on 113 infants born at 22 to 24 weeks' gestation from January 1991 through April 2006 were analyzed by a case-control approach. Cesarean section, Apgar score or= 24 hours, pulmonary hemorrhage and intraventricular hemorrhage (IVH) were significantly associated with death by day 6. Among those surviving >or= 7 days, sepsis and severe IVH were significantly associated with death. Assessment of survivors at a minimum follow-up period of 2 years revealed that protracted mechanical ventilation was significantly associated with a poor neurological outcome. There are various characteristic key events in relation to the outcome at different ages of life in EPI born at 22 to 24 weeks' gestation. Clinicians and parents should discuss management options for the infant on the basis of these findings.

    Autism spectrum disorders (ASD) are recognized as a major public health issue. Here, we evaluated the effects of folic acid intervention on methylation cycles and oxidative stress in autistic children enrolled in structured teaching. Sixty-six autistic children enrolled in this open-label trial and participated in three months of structured teaching. Forty-four children were treated with 400 μg folic acid (two times/daily) for a period of three months during their structured teaching (intervention group), while the remaining 22 children were not given any supplement for the duration of the study (control group). The Autism Treatment Evaluation Checklist (ATEC) and Psychoeducational Profile-third edition (PEP-3) were measured at the beginning and end of the treatment period. Folic acid, homocysteine, and glutathione metabolism in plasma were measured before and after treatment in 29 autistic children randomly selected from the intervention group and were compared with 29 age-matched unaffected children (typical developmental group). The results illustrated folic acid intervention improved autism symptoms towards sociability, cognitive verbal/preverbal, receptive language, and affective expression and communication. Furthermore, this treatment also improved the concentrations of folic acid, homocysteine, and normalized glutathione redox metabolism. Folic acid supplementation may have a certain role in the treatment of children with autism. PMID:27338456

    Objective: To evaluate the effectiveness of lurasidone as maintenance treatment for schizophrenia. Method: Adults experiencing an acute exacerbation of schizophrenia initially received 12–24 weeks of open-label treatment with lurasidone (40–80 mg/d, flexibly dosed). Patients who maintained clinical stability for ⩾12 weeks were randomized in double-blind fashion to placebo or lurasidone (40–80 mg/d, flexibly dosed) for an additional 28-week treatment period. The primary efficacy endpoint was time to relapse (based on Kaplan–Meier survival analysis). Results: A total of 676 patients enrolled in the open-label phase; 285 met protocol-specified stabilization criteria and were randomized to lurasidone (N=144) or placebo (N=141). During the open-label phase, mean Positive and Negative Syndrome Scale total score decreased from 90.1 to 54.4 in patients who met clinical stability criteria and were randomized. In the double-blind phase, lurasidone significantly delayed time to relapse compared with placebo (log-rank test, p=0.039), reflecting a 33.7% reduction in risk of relapse (Cox hazard ratio (95% confidence interval), 0.663 (0.447–0.983); p=0.041). Probability of relapse at the double-blind week 28 endpoint (based on Kaplan–Meier analysis) was 42.2% in the lurasidone group and 51.2% in the placebo group. Minimal changes in weight, lipid, glucose, and prolactin were observed throughout the study. Conclusions: This multicenter, placebo-controlled, randomized withdrawal study demonstrated the efficacy of lurasidone for the maintenance treatment of patients with schizophrenia. PMID:26645209

    An animal model with brain growth similar to humans, that can be used in MRI studies to investigate brain development, would be valuable. Our laboratory has developed and validated MRI methods for regional brain volume quantification in the neonatal piglet. The aim of this study was to utilize the MRI-based volume quantification technique in a longitudinal study to determine brain growth in domestic pigs from 2 to 24 weeks of age. MRI data were acquired from pigs 2-24 weeks of age using a 3-dimensional magnetization-prepared gradient echo sequence on a Magnetom Trio 3-tesla imager. Manual segmentation was performed for volume estimates of total brain, cortical, diencephalon, brainstem, cerebellar and hippocampal regions. Logistic modeling procedures were used to characterize brain growth. Total brain volume increased 130% (±12%) and 121% (±7%) from 2 to 24 weeks in males and females, respectively. The maximum increase in total brain volume occurred about the age of 4 weeks and 95% of whole brain growth occurred by the age of 21-23 weeks. Logistical modeling suggests there are sexually dimorphic effects on brain growth. For example, in females, the cortex was smaller (p = 0.04). Furthermore, the maximum growth of the hippocampus occurred about 5 weeks earlier in females than males, and the window for hippocampal growth was significantly shorter in females than males (p = 0.02, p = 0.002 respectively). These sexual dimorphisms are similar to what is seen in humans. In addition to providing important data on brain growth for pigs, this study shows pigs can be used to obtain longitudinal MRI data. The large increase in brain volume in the postnatal period is similar to that of human neonates and suggests pigs can be used to investigate brain development.

    A 24-week premature infant developed severe right-sided pulmonary barotrauma secondary to mechanical ventilation for respiratory distress syndrome (RDS). High-frequency oscillatory ventilation and permissive hypercapnia were initiated. A chest tube was placed to relieve a pneumothorax, and a catheter was inserted into an air-filled cyst for drainage. These maneuvers failed to improve the child's respiratory status. The child's left main-stem bronchus was then successfully fiberoptically intubated for single-lung ventilation in order to reduce the unilateral barotrauma. Single-lung ventilation was effectively and safely continued for 5 days, with complete resolution of the pulmonary barotrauma.

    Faldaprevir is an investigational hepatitis C virus (HCV) NS3/4A protease inhibitor which, when administered for 24 weeks in combination with pegylated interferon α-2a and ribavirin (PegIFN/RBV) in treatment-naive patients in a prior study (SILEN-C1; M. S. Sulkowski et al., Hepatology 57:2143–2154, 2013, doi:10.1002/hep.26276), achieved sustained virologic response (SVR) rates of 72 to 84%. The current randomized, open-label, parallel-group study compared the efficacy and safety of 12 versus 24 weeks of 120 mg faldaprevir administered once daily, combined with 24 or 48 weeks of PegIFN/RBV, in 160 treatment-naive HCV genotype 1 patients. Patients with maintained rapid virologic response (HCV RNA of <25 IU/ml at week 4 and undetectable at weeks 8 and 12) stopped all treatment at week 24, otherwise they continued PegIFN/RBV to week 48. SVR was achieved by 67% and 74% of patients in the 12-week and 24-week groups, respectively. Virologic response rates were lower in the 12-week group from weeks 2 to 12, during which both groups received identical treatment. SVR rates were similar in both groups for patients achieving undetectable HCV RNA. Most adverse events were mild or moderate, and 6% of patients in each treatment group discontinued treatment due to adverse events. Once-daily faldaprevir at 120 mg for 12 or 24 weeks with PegIFN/RBV resulted in high SVR rates, and the regimen was well tolerated. Differences in the overall SVR rates between the 12-week and 24-week groups were not statistically significant and possibly were due to IL28B genotype imbalances; IL28B genotype was not tested, as its significance was not known at the time of the study. These results supported phase 3 evaluation. (This study has been registered at ClinicalTrials.gov under registration no. NCT00984620). PMID:24709256

    Study Objectives: Rapid eye movement (REM) sleep behavior disorder (RBD) is a parasomnia characterized by REM sleep without atonia and elaborate motor activity in association with dream mentation. The melatonin receptor agonist ramelteon has been documented as being effective in two patients with secondary RBD. However, there are no reports on ramelteon treatment for idiopathic RBD. Methods: In an open-labeled trial, we treated 12 consecutive patients with idiopathic RBD for at least 4 w with 8 mg ramelteon given within 30 min before bedtime. Results: Ramelteon treatment did not have a clear effect on REM sleep without atonia or an RBD severity scale measured by video-supported polysomnography. However, clinical assessment using a visual analog scale showed a trend toward significance and there were also definitely positive changes in some individual cases. Ramelteon was well tolerated in most patients, with minor side effects. Conclusions: Considering that ramelteon is associated with few side effects, further study may ascertain whether patients with RBD could be effectively treated by ramelteon, especially when clonazepam may not be suitable due to its side effects.

Design: Multicenter open-label study with all patients receiving above-mentioned treatment for up to 24 weeks. Setting: Private dermatology and plastic surgery clinics and clinical research facilities. Participants: Thirty-seven adult females with moderate or marked epidermal melasma, melasma pigmentation of mild-to-marked intensity and Fitzpatrick skin type III to VI. Measurements: Melasma severity melasma pigmentation intensity melasma improvement, patient satisfaction, quality-of-life measures, erythema, dryness, peeling, burning/stinging. Results: No patient discontinued due to lack of efficacy or treatment-related adverse events. Treatment was associated with a significant reduction from baseline in melasma severity and melasma pigmentation intensity from Week 4 onward (P≤0.001), and 100 percent of patients showed improvement from Week 8 onward. At Week 24, 100 percent of patients were “satisfied” or “very satisfied” with the overall effectiveness of their treatment. Patients’ quality of life also improved (e.g., the proportion of patients feeling embarrassed or self-conscious about their skin “a lot” or “very much” declined from 78 percent at baseline to four percent at Week 24). Mean and median scores for erythema, dryness, peeling, and burning/stinging did not exceed trace levels. Conclusion: Treating moderate-to-severe melasma using the 4% hydroquinone skin care system plus 0.05% tretinoin can significantly reduce the severity of melasma and the intensity of melasma pigmentation within four weeks. Treatment was generally well tolerated and associated with an improved quality of life and high levels of patient satisfaction. PMID:24307923

    Action myoclonus frequently remains the primary cause of disability in Unverricht-Lundborg disease (EPM1) patients. Pharmacological treatment of myoclonus in these patients continues to be challenging; indeed conventional AEDs may be poorly effective in monotherapy or even in combination. We carried out a pilot, open-label trial of add-on zonisamide (ZNS) in patients with EPM1. Twelve EPM1 patients with epilepsy and action myoclonus were included in the study. Oral ZNS was gradually titrated until the target dose of 6 mg/Kg/day. Unified Myoclonus Rating Scale was obtained in each subject before and after ZNS add-on. A significant reduction of myoclonus severity was reached after ZNS introduction. ZNS was generally well tolerated and only two patients withdrew due to mild adverse effects. Our trial suggests that ZNS may be a valuable therapeutic option in EPM1 patients.

    To date, placebo-controlled drug trials targeting the core social impairment of autistic disorder (autism) have had uniformly negative results. Given this, the search for new potentially novel agents targeting the core social impairment of autism continues. Acamprosate is U.S. Food and Drug Administration-approved drug to treat alcohol dependence. The drug likely impacts both gamma-aminobutyric acid and glutamate neurotransmission. This study describes our initial open-label experience with acamprosate targeting social impairment in youth with autism. In this naturalistic report, five of six youth (mean age, 9.5 years) were judged treatment responders to acamprosate (mean dose 1,110 mg/day) over 10 to 30 weeks (mean duration, 20 weeks) of treatment. Acamprosate was well tolerated with only mild gastrointestinal adverse effects noted in three (50%) subjects.

    Freezing of gait (FOG) and falls are major sources of disability for Parkinson's disease (PD) patients, and show limited responsiveness to medications. We assessed the efficacy of visual cues for overcoming FOG in an open-label study of 26 patients with PD. The change in the frequency of falls was a secondary outcome measure. Subjects underwent a 1-2 month baseline period of use of a cane or walker without visual cues, followed by 1 month using the same device with the laserlight visual cue. The laserlight visual cue was associated with a modest but significant mean reduction in FOG Questionnaire (FOGQ) scores of 1.25 ± 0.48 (p = 0.0152, two-tailed paired t-test), representing a 6.6% improvement compared to the mean baseline FOGQ scores of 18.8. The mean reduction in fall frequency was 39.5 ± 9.3% with the laserlight visual cue among subjects experiencing at least one fall during the baseline and subsequent study periods (p = 0.002; two-tailed one-sample t-test with hypothesized mean of 0). Though some individual subjects may have benefited, the overall mean performance on the timed gait test (TGT) across all subjects did not significantly change. However, among the 4 subjects who underwent repeated testing of the TGT, one showed a 50% mean improvement in TGT performance with the laserlight visual cue (p = 0.005; two-tailed paired t-test). This open-label study provides evidence for modest efficacy of a laserlight visual cue in overcoming FOG and reducing falls in PD patients.

    The doctor-patient relationship is built on an implicit covenant of trust, yet it was not until the post-World War Two era that respect for patient autonomy emerged as an article of mainstream medical ethics. Unlike their medical forebears, physicians today are expected to furnish patients with adequate information about diagnoses, prognoses and treatments. Against these dicta there has been ongoing debate over whether placebos pose a threat to patient autonomy. A key premise underlying medical ethics discussion is the notion that the placebo effect necessitates patient deception. Indeed, the American Medical Association guidelines imply that placebo treatment necessary entails a form of deception. As a consequence of this assumption, the fulcrum of debate on the use of placebo treatment has hinged on whether that deception is ever justified. Recently performed experiments with open-label transparently prescribed placebos have begun to challenge the notion that deception is necessary in eliciting the placebo effect and such effects necessarily involve a binary distinction between autonomy and beneficence. In this article we focus on the content of disclosures in distinctive open-label, transparently disclosed placebo studies and inquire whether they might be said to invoke deception in clinical contexts, and if so, whether the deception is unethical. We find that open placebos may be said to involve equivocation over how placebos work. However, drawing on surveys of patient attitudes we suggest that this equivocation appears to be acceptable to patients. We conclude that open placebos fulfil current American Medical Association guidelines for placebo use, and propose future research directions for harnessing the placebo effect ethically.

    Persistent pain following back surgery remains a major treatment challenge. The primary objective of this open-label exploratory study was to investigate the analgesic effectiveness of pulsed electromagnetic field therapy administered twice daily over a 45-day period in 34 subjects (68% female) with persistent or recurrent pain following back surgery. A secondary goal was to guide the design of future randomized controlled trials that could target responsive subpopulations. All predefined primary and secondary outcomes, including change in pain intensity (PI), physical function (Oswestry Disability Index), analgesic consumption, and overall well-being (Patient Global Impression of Change), are reported. A responder analysis (≥30% reduction in PI versus baseline) was added as a post hoc evaluation. Safety outcomes, as well as results of a cost-avoidance survey, are also summarized. Of the 30 per-protocol subjects who completed the study, 33% reported a clinically meaningful (≥30%) reduction in PI. A higher response rate (60%) was reported for subjects who had undergone discectomy prior to the trial compared to subjects who had undergone other types of surgical interventions (decompression or fusion) without discectomy. Improvements in PI were paralleled by improvements in secondary outcomes. Relative to baseline, responders reported an average 44% and 55% reduction in back PI and leg PI (respectively), and an average 13% improvement in Oswestry Disability Index scores. In the per-protocol population, 50% of responders and 12% of nonresponders reported less analgesia consumption at the end of treatment versus baseline. Sixty-seven percent of per-protocol responders and 0% of nonresponders reported clinically meaningful improvement in overall well-being on the Patient Global Impression of Change scale.

    Although trihexyphenidyl is used clinically to treat both primary and secondary dystonia in children, limited evidence exists to support its effectiveness, particularly in dystonia secondary to disorders such as cerebral palsy. A prospective, open-label, multicenter pilot trial of high-dose trihexyphenidyl was conducted in 23 children aged 4 to 15 years with cerebral palsy judged to have secondary dystonia impairing function in the dominant upper extremity. All children were given trihexyphenidyl at increasing doses over a 9-week period up to a maximum of 0.75 mg/kg/d. Trihexyphenidyl was subsequently tapered off over the next 5 weeks. Objective motor assessments were performed at baseline, 9 weeks, and 15 weeks. The primary outcome measure was the Melbourne Assessment of Unilateral Upper Limb Function, tested in the dominant arm. Tolerability and safety were monitored closely throughout the trial. Of the 31 children who agreed to participate in the study, 5 failed to meet entry criteria and 3 withdrew due to nonserious adverse events (chorea, drug rash, and hyperactivity). Three children required a dosage reduction because of nonserious adverse events but continued to participate. The 23 children who completed the study showed a significant improvement in arm function at 15 weeks (P = .045) but not at 9 weeks (P = .985). Post hoc analysis showed that a subgroup (n = 10) with hyperkinetic dystonia (excess involuntary movements) worsened at 9 weeks (P = .04) but subsequently returned to baseline following taper of the medicine. The authors conclude that scientific evidence for the clinical use of trihexyphenidyl in cerebral palsy remains equivocal. Trihexyphenidyl may be a safe and effective for treatment for arm dystonia in some children with cerebral palsy if given sufficient time to respond to the medication. Post hoc analyses based on the type of movement disorder suggested that children with hyperkinetic forms of dystonia may worsen. A larger, randomized

    Introduction: Although adjunctive aripiprazole improves hyperprolactinemia, sufficient evidence for its effects on sexual dysfunction has not been obtained. We assessed the usefulness of adjunctive aripiprazole for schizophrenia with sexual dysfunction. Methods: 22 Japanese schizophrenia patients with antipsychotic-induced hyperprolactinemia and sexual dysfunction were enrolled, and 19 of them completed the study. Aripiprazole was administrated in a flexible titration schedule to participants according to the judgment of each doctor, and patients were followed for 24 weeks. Serum prolactin, Clinical Global Impression Scales-Severity (CGI-S), and Nagoya Sexual Function Questionnaire (NSFQ) were measured at baseline and at 4, 8, 12, and 24 weeks. Results: Prolactin at week 4 and later was significantly lower than that at baseline. Compared to baseline, we observed a significant improvement in total sexual dysfunction as measured by NSFQ at week 8 and later. In males, erectile dysfunction was significantly reduced at week 24. In females, menstrual irregularity and galactorrhea were significantly reduced at week 24. CGI-S did not significantly change. Discussion: Although the small sample size is a limitation in this study, adjunctive aripiprazole may be useful treatment for sexual dysfunction including hyperprolactinemia in schizophrenia.

    Adults (≥55 years) with self-reported cognitive complaints (sCC) were randomized to: multiple-modality exercise (M2), or multiple-modality plus mind-motor exercise (M4), for 24-weeks. Participants (n = 58) were assessed on antisaccade reaction time (RT) to examine executive-related oculomotor control and self-reported physical activity (PA) at pre-intervention (V0), post-intervention (V1), and 52-weeks follow-up (V2). We previously reported significant improvements in antisaccade RT of 23 ms at V1, in both groups. We now report maintenance of antisaccade RT improvement from V1 to V2, t(57) = 0.8, p = 0.45, and improved PA from V1 to V2, t(56) = -2.4, p = 0.02. Improvements in executive-related oculomotor control attained at V1 were maintained at V2.

    Two hundred and forty-six patients infected with human immunodeficiency virus (HIV) who also had disseminated Mycobacterium avium complex received either azithromycin 250 mg every day, azithromycin 600 mg every day, or clarithromycin 500 mg twice a day, each combined with ethambutol, for 24 weeks. Samples drawn from patients were cultured and clinically assessed every 3 weeks up to week 12, then monthly thereafter through week 24 of double-blind therapy and every 3 months while on open-label therapy through the conclusion of the trial. The azithromycin 250 mg arm of the study was dropped after an interim analysis showed a lower rate of clearance of bacteremia. At 24 weeks of therapy, the likelihood of patients' developing 2 consecutive negative cultures (46% vs. 56%, P=.24) or 1 negative culture (59% vs. 61%, P=.80) was similar for azithromycin 600 mg (n=68) and clarithromycin (n=57), respectively. The likelihood of relapse was 39% versus 27% (P=.21) on azithromycin compared with clarithromycin, respectively. Of the 6 patients who experienced relapse, none of those randomized to receive azithromycin developed isolates resistant to macrolides, compared with 2 of 3 patients randomized to receive clarithromycin [corrected]. Mortality was similar in patients comprising each arm of the study (69% vs. 63%; hazard, 95.1% confidence interval, 1.1 [0.7, 1.7]). Azithromycin 600 mg, when given in combination with ethambutol, is an effective agent for the treatment of disseminated M. avium disease in patients infected with HIV.

    This open-label multicenter study evaluated the long-term safety and efficacy of intrathecal ziconotide and included 78 patients with chronic pain who had completed one of two previous ziconotide clinical trials. Each patient's initial ziconotide dose was based on his or her dose from the study of origin and was adjusted as necessary on the basis of adverse events and analgesic effect. The median ziconotide dose was 6.48 mcg/day (range, 0.00-120.00 mcg/day) at the Initial Visit and ranged from 5.52 to 7.20 mcg/day across all study visits. The most commonly reported new adverse events that were considered ziconotide related were memory impairment (11.3%); dizziness, nystagmus, and speech disorder (8.5% each); nervousness and somnolence (7.0% each); and abnormal gait (5.6%). There was no evidence of increased adverse event incidence at higher cumulative ziconotide doses. Elevations in creatine kinase were noted, but the proportion of patients with creatine kinase elevations did not change from the Initial Visit to the Termination Visit (4.1% each). Stable mean Visual Analog Scale of Pain Intensity scores during the three years of the study suggested no evidence of increased pain intensity with increased duration of ziconotide exposure. Long-term treatment with ziconotide appeared to be well tolerated and effective in patients whose response to ziconotide and ability to tolerate the drug had been previously demonstrated.

    Aripiprazole is a novel antipsychotic medication characterized by partial agonism at the D2 and 5-HT1A receptors and by antagonism at the 5-HT2A receptor. The aim of the present study was to evaluate, in an open-label pilot study, the effects and safety of very small doses of aripiprazole on L-dopa-induced dyskinesia of a group of PD patients who did not show a significant clinical benefit by pharmacological treatment with amantadine and mirtazapine. Twelve PD patients with peak-dose LID were enrolled in a period of 1 year. Aripiprazole dosage was of 0.625 mg/day. The ten patients who continued taking aripiprazole displayed a significant decrease in the intensity and frequency of dyskinesias in all parts of the body, particularly in trunk movements (AIMS score T(0) = 14.1 +/- 3.6 vs. final score 2.4. +/- 2.6; P = 0.005). Our study suggests that aripiprazole at very low doses is tolerated and could be efficacy in treating LID.

    Viral warts, which are caused by the human papilloma virus, are a common problem in dermatology. Various modalities have been used to treat warts, but none are uniformly effective or directly antiviral. Recent studies show that oral zinc sulfate could be effective in the treatment of viral warts. Thirty-one patients with multiple, non-genital viral warts were recruited in this open-label clinical study. The patients were treated with oral zinc sulfate (10 mg/kg to a maximum dose of 600 mg/day) for 2 months and followed up with assessments for the resolution of their warts and for any evidence of recurrence after treatment. Among the 31 patients, 18 patients showed low serum zinc levels (58%). Of 26 patients who completed the study (84%), 13 (50%) showed complete resolution of their warts after 2 months of treatment. Complete responders remained free of lesions at 6-month follow-up. No serious side-effects were reported apart from nausea (16%), mild gastric pain (3%) and itching sensation (3%). Oral zinc sulfate was found to be a good option in the treatment of viral warts, as it was safe and effective without important side-effects.

    The present open-label study assessed the efficacy of zuclopenthixol, an thioxanthene neuroleptic with combined dopamine receptors (D1/D2) antagonist activity, in the treatment of severe behavioral disturbances in mentally retarded children and adolescents. A sample of 15 (11 males, 4 females) mentally retarded children and adolescents, ages 5-18 years (12.2 +/- 2.3 [mean +/- SD] years), all exhibiting severe behavioral disturbances, was evaluated. The 12-week zuclopenthixol treatment (up to 26 mg/day) was initiated after a week's washout from previous antipsychotic agents. An assessment of the behavioral disturbances was performed using the 14-item Checklist for Behavior Problems Involving Limited or No Social Awareness (CBP-NSA). The Udvalg for kliniske undersøgelser (UKU) Side Effect Rating Scale was used to assess the pharmacologic side effects. Results show a significant reduction in total CBP-NSA scores and in individual items such as hyperactivity, aggressive behavior, and temper tantrums (p < 0.001 for each). It seems that zuclopenthixol monotherapy is effective and well tolerated in the treatment of severe behavioral disturbances in mentally retarded children and adolescents. Double-blind, placebo-controlled studies are needed before definitive conclusions can be drawn regarding the efficacy and safety of zuclopenthixol for this population.

    Leflunomide is an effective drug used in the treatment of rheumatoid arthritis. Here we report the findings of an open-label pilot study, which found that leflunomide is also an effective treatment for myasthenia gravis (MG). This study recruited 15 corticosteroid-dependent MG patients. For 6 months, leflunomide 20 mg was given to these patients daily along with prednisone. The quantitative myasthenia gravis (QMG) scores and MG activities of daily living (MG-ADL) profiles were measured in these MG patients. After 6 months of treatment, 9 of the 15 patients enrolled in this study showed improvements in both QMG and MG-ADL. The mean QMG scores (13.4 to 8.5) and MG-ADL profiles (5.8 to 2.8) were significantly decreased (P = 0.01, 0.006 respectively). Furthermore, we found that the mean corticosteroid doses were reduced after treatment with leflunomide (24.3 to 12.3 mg per day). Leflunomide is a well-tolerated and efficacious treatment for corticosteroid-dependent MG, which may also enable lower doses of corticosteroids to be administered.

    Sleep disturbances represent important predictors of poor quality of life (QoL) in Parkinson's disease (PD). This open-label pilot study aimed to objectively assess, by means of actigraphic recording, effect of rotigotine on sleep in PD patients with self-reported sleep complaints. 15 PD patients underwent one-week actigraphic recording before (T0) and during (T1) rotigotine treatment, which was titrated to the dose subjectively improving motor symptoms (4–8 mg/24 h). Sleep disturbances, daytime sleepiness, cognitive performance, QoL, and depression were also evaluated with questionnaires. Actigraphic recordings showed a significant reduction in nocturnal motor activity and mean duration of wake episodes after sleep onset during rotigotine treatment compared to baseline. In 10 patients presenting objective evidence of poor sleep quality at T0 (sleep efficiency ≤ 85%), rotigotine also significantly improved other sleep parameters and further reduced nocturnal motor activity and mean duration of wake episodes. A significant decrease in number and duration of daytime sleep episodes was also observed at T1. Finally we confirmed that rotigotine significantly improves perceived sleep quality and QoL. Our study showed for the first time that rotigotine is associated with an objective improvement of nocturnal and diurnal sleep disturbances in PD patients with self-reported sleep complaints. This study is registered with AIFA-observational study registry number 12021. PMID:26981312

The primary endpoint was trough forced expiratory volume in 1 s (FEV1) at day 85 in the per-protocol population. Other endpoints included: weighted mean FEV1 over 0–24 h and patient-reported outcomes (transition dyspnoea index score and St George's Respiratory Questionnaire total score). Adverse events were also assessed. A total of 1037 patients were randomised to treatment. Umeclidinium was non-inferior (margin: −50 mL) to glycopyrronium (trough FEV1 at day 85 treatment difference: 24 mL, 95% confidence intervals: −5–54). Improvements in other endpoints were similar between treatments. Adverse event incidences were similar for umeclidinium (37%) and glycopyrronium (36%). Once-daily umeclidinium was non-inferior to once-daily glycopyrronium in patients with chronic obstructive pulmonary disease in trough FEV1 at day 85. Patient-reported outcomes and safety profiles were similar for both treatments. PMID:27730198

    Objective This was a first pilot study evaluating the acute phase (8-week) efficacy of the antidepressant medication mirtazapine for the treatment of depressive symptoms and drinking of subjects with comorbid major depressive disorder and alcohol dependence (MDD/AD). We hypothesized that mirtazapine would demonstrate within-group efficacy for the treatment of both depressive symptoms and drinking in these subjects. Methods We conducted a first open label study of the second generation antidepressant mirtazapine in 12 adult outpatient subjects with comorbid major depressive disorder/alcohol dependence. The pharmacological profile of that medication is unique among antidepressants, unrelated to tricyclics or selective serotonin reuptake inhibitors. Results Mirtazapine was well tolerated in this treatment population. Self-reported depressive symptoms decreased from 31.8 to 8.3 on the Beck Depression Inventory, a 74.0% decrease (p<0.001), and drinking decreased from 33.9 to 13.3 drinks per week, a 60.8% decrease (p<0.05). None of the subjects were employed full-time at baseline, but 9 of the 12 (75%) were employed full-time at end-of-study. Conclusions These preliminary findings suggest efficacy for mirtazapine for treating both the depressive symptoms and excessive alcohol use of comorbid major depressive disorder and alcohol dependence. Double-blind studies are warranted to further clarify the efficacy of mirtazapine in this population. PMID:23230395

    Anhedonia is a cardinal symptom of major depression and is often refractory to standard treatment, yet no approved medication for this specific symptom exists. In this exploratory re-analysis, we assessed whether administration of rapid-acting antidepressant ketamine was associated specifically with reduced anhedonia in medication-free treatment-refractory patients with major depressive disorder in an open-label investigation. Additionally, participants received either oral riluzole or placebo daily beginning 4 hours post-infusion. A subgroup of patients underwent fluorodeoxyglucose positron emission tomography scans at baseline (1-3 days pre-infusion) and 2 hours post-ketamine infusion. Anhedonia rapidly decreased following a single ketamine infusion; this was sustained for up to three days, but was not altered by riluzole. Reduced anhedonia correlated with increased glucose metabolism in the hippocampus and dorsal anterior cingulate cortex (dACC) and decreased metabolism in the inferior frontal gyrus and orbitofrontal cortex (OFC). The tentative relationship between change in anhedonia and glucose metabolism remained significant in dACC and OFC, and at trend level in the hippocampus, a result not anticipated, when controlling for change in total depression score. Results, however, remain tenuous due to the lack of a placebo control for ketamine. In addition to alleviating overall depressive symptoms, ketamine could possess anti-anhedonic potential in major depressive disorder, which speculatively, may be mediated by alterations in metabolic activity in the hippocampus, dACC and OFC.

    Studies designed specifically for the pediatric population are needed to assess the tolerability and safety of the new antiepileptic drugs. The purpose of this study was to document the safety, ease of dosing, and acceptance of oxcarbazepine oral suspension in pediatric patients in monotherapy and polytherapy. A prospective, multicenter, open-label study was conducted at the neurology services of three pediatric university hospitals over 12 months. After obtaining signed informed consent, we enrolled a series of 62 patients with epilepsy aged between 2 months and 14 years who began oxcarbazepine treatment in monotherapy or in combination with other antiepileptic drugs to assess the seizure frequency, safety (adverse events), and acceptance of the pharmaceutical form by the patient's family. Fifty patients (80.6%) reduced seizures by at least 50%, 44 (71%) saw a reduction in seizure frequency of over 75%, and 29 (46.8%) were seizure free at the end of the study. The difference in the number of seizures before and after the study was statistically significant, both overall and by type of pathology. Adverse events occurred in four patients (6.4%) and required withdrawal of the drug in two cases (skin rash); three patients (4.8%) withdrew for inefficacy. Five patients (8.1%) withdrew from the treatment. We concluded that, in this series of patients, oxcarbazepine in oral suspension form was seen to help reduce seizure frequency, to have few side effects, and to be accepted by parents and patients.

    Background: Isolated fucoidans from brown marine algae have been shown to have a range of anti-inflammatory effects. Purpose: This present study tested a Maritech® extract formulation, containing a blend of extracts from three different species of brown algae, plus nutrients in an open label combined phase I and II pilot scale study to determine both acute safety and efficacy in osteoarthritis of the knee. Patients and methods: Participants (n = 12, five females [mean age, 62 ± 11.06 years] and seven males [mean age, 57.14 ± 9.20 years]) with a confirmed diagnosis of osteoarthritis of the knee were randomized to either 100 mg (n = 5) or 1000 mg (n = 7) of a Maritech® extract formulation per day. The formulation contained Maritech® seaweed extract containing Fucus vesiculosis (85% w/w), Macrocystis pyrifera (10% w/w) and Laminaria japonica (5% w/w) plus vitamin B6, zinc and manganese. Primary outcome was the average comprehensive arthritis test (COAT) score which is comprised of four sub-scales: pain, stiffness, difficulty with physical activity and overall symptom severity measured weekly. Safety measures included full blood count, serum lipids, liver function tests, urea, creatinine and electrolytes determined at baseline and week 12. All adverse events were recorded. Results: Eleven participants completed 12 weeks and one completed 10 weeks of the study. Using a multilevel linear model, the average COAT score was reduced by 18% for the 100 mg treatment and 52% for the 1000 mg dose at the end of the study. There was a clear dose response effect seen between the two treatments (P ≤ 0.0005) on the average COAT score and each of the four COAT subscales (pain, stiffness, difficulty with physical activity and overall symptom severity) (P ≤ 0.05). The preparation was well tolerated and the few adverse events were unlikely to be related to the study medication. There were no changes in blood parameters measured over the course of the study with the exception of

    Previous studies have demonstrated that combined total sleep deprivation (Wake therapy), sleep phase advance, and bright light therapy (Triple Chronotherapy) produce a rapid and sustained antidepressant effect in acutely depressed individuals. To date no studies have explored the impact of the intervention on unipolar depressed individuals with acute concurrent suicidality. Participants were suicidal inpatients (N = 10, Mean age = 44 ± 16.4 SD, 6F) with unipolar depression. In addition to standard of care, they received open label Triple Chronotherapy. Participants underwent one night of total sleep deprivation (33-36 h), followed by a three-night sleep phase advance along with four 30-min sessions of bright light therapy (10,000 lux) each morning. Primary outcome measures included the 17 item Hamilton depression scale (HAM17), and the Columbia Suicide Severity Rating Scale (CSSRS), which were recorded at baseline prior to total sleep deprivation, and at protocol completion on day five. Both HAM17, and CSSRS scores were greatly reduced at the conclusion of the protocol. HAM17 scores dropped from a mean of 24.7 ± 4.2 SD at baseline to a mean of 9.4 ± 7.3 SD on day five (p = .002) with six of the ten individuals meeting criteria for remission. CSSRS scores dropped from a mean of 19.5 ± 8.5 SD at baseline to a mean of 7.2 ± 5.5 SD on day five (p = .01). The results of this small pilot trial demonstrate that adjunctive Triple Chronotherapy is feasible and tolerable in acutely suicidal and depressed inpatients. Limitations include a small number of participants, an open label design, and the lack of a comparison group. Randomized controlled studies are needed.

    Developmental exposure of mice to the environmental contaminant and AhR agonist, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), causes persistent postnatal suppression of T cell-mediated immune responses. The extent to which prenatal TCDD may induce or exacerbate postnatal autoimmune disease remains unknown. In the present study, time-pregnant high affinity AhR C57BL/6 mice received a single oral administration of 0, 2.5, or 5 {mu}g/kg TCDD on gestation day (gd) 12. Offspring of these mice (n = 5/gender/treatment) were evaluated at 24 weeks-of-age and showed considerable immune dysregulation that was often gender-specific. Decreased thymic weight and percentages of CD4{sup +}CD8{sup +} thymocytes, and increased CD4{sup +}CD8{sup -} thymocytes, were present in the female but not male offspring. Males but not females showed decreased CD4{sup -}CD8{sup +} T cells, and increased V{beta}3{sup +} and V{beta}17a{sup +} T cells, in the spleen. Males but not females also showed increased percentages of bone marrow CD24{sup -}B220{sup +} B cell progenitors. Antibody titers to dsDNA, ssDNA and cardiolipin displayed increasing trends in both male and female mice, reaching significance for anti-dsDNA in both genders and for ssDNA in males at 5 {mu}g/kg TCDD. Immunofluorescent staining of IgG and C3 deposition in kidney glomeruli increased in both genders of prenatal TCDD-exposed mice, suggestive of early stages of autoimmune glomerulonephritis. Collectively, these results show that exposure to TCDD during immune system development causes persistent humoral immune dysregulation as well as altered cell-mediated responses, and induces an adult profile of changes suggestive of increased risk for autoimmune disease.

    Introduction: This study evaluated the prevalence and progression of subclinical carotid artery atherosclerosis in active rheumatoid arthritis (RA). Methods: Carotid arteries of RA patients were scanned using 3D ultrasound at baseline and 24 weeks for total plaque area, vessel wall volume, and intima-media thickness (IMT), as well as arterial stiffness measured using pulse wave velocity. Variables related to inflammation, lipids and cardiovascular (CV) risk were assessed for associations with plaque progression. Of 195 screened patients, 31 met inclusion criteria (66 Swollen joint count (SJC) plus 68 Tender joint count (TJC)≥8 OR SJC plus TJC≥4 with elevated acute phase reactants) and were enrolled (27 female; mean age 59.3±9.8years). Patients using lipid lowering drugs and uncontrolled comorbidities were excluded. Results: Atherosclerotic plaque occurred in 35% and arterial wall hypertrophy (IMT≥0.6mm) in 86% of patients. Most (68%) had an abnormal lipid profile characterized by reduced HDL and/or increased total cholesterol/HDL index, which was adversely affected by disease activity. Stepwise binary logistic regression analysis showed that Framingham risk score (OR=1.155, 95%CI:1.002-1.332, p=0.046) and ESR (OR=1.148, 95%CI:1.015-1.299, p=0.028) predicted plaque burden most strongly. Plaque progression was significantly associated with baseline higher hsCRP, ESR, and heavy smoking, but only hsCRP predicted plaque growth in multivariate regression analysis (p=0.004); and hsCRP was related to higher disease activity (r=0.443, p=0.016), LDL (r=0.544, p=0.007), and smoking (r=0.384, p=0.04). Conclusion: RA-related inflammation contributed to augmented CV burden in RA and might mediate its effect on atherosclerosis through hsCRP and modulation of the traditional CV risk factors, such as dyslipidemia.

    One limitation of several recent 24 week Alzheimer's disease (AD) clinical trials was the lack of cognitive decline detected by the AD Assessment Scale-cognitive subscale (ADAS-cog) in the placebo groups, possibly obscuring true medication effects. Data from 733 individuals in the placebo arms of six AD clinical trials performed 1996-1997 were pooled to examine the relationship of clinical, demographic, and genetic characteristics with the 24 week change in ADAS-cog. Baseline cognitive and functional status and the screening-to-baseline change in ADAS-cog were the strongest independent predictors of the 24 week change in ADAS-cog. The ADAS-cog did not detect progression in patients with mild dementia (screening Mini-Mental State Exam, MMSE, >or=20). The change in ADAS-cog from screening to baseline was inversely correlated with the 24 week change score; it was more difficult to detect cognitive decline at 24 weeks if individuals markedly worsened from screening to baseline. The effects of baseline MMSE and screening-to-baseline change in ADAS-cog generalized to the placebo group (N=106) of another AD study performed in 2004-2005. Overcoming lack of placebo decline in AD clinical trials will require scales more sensitive to cognitive decline in mild AD and strategies to reduce within-person variability in outcome measures.

    Aims To compare the efficacy and safety of two insulin intensification strategies in patients with type 2 diabetes inadequately controlled on basal insulin glargine with metformin and/or pioglitazone. Methods A multinational, randomized, open-label trial that compared insulin lispro low mixture (LM25; n = 236) twice daily with a basal–prandial regimen of insulin glargine once daily and insulin lispro once daily (IGL; n = 240) over 24 weeks in patients with HbA1c 7.5–10.5% and fasting plasma glucose ≤6.7 mmol/l. The primary objective was to assess non-inferiority [per-protocol (PP) population], and then superiority [intention-to-treat (ITT) population], of LM25 versus IGL according to change in HbA1c after 24 weeks (non-inferiority margin 0.4%, two-sided significance level 0.05). Results Estimated change [least squares (LS) mean (95% CI)] in HbA1c after 24 weeks: −1.30 (−1.44, −1.16)% with LM25 and −1.08 (−1.22, −0.94)% with IGL. Non-inferiority was shown [LS mean (95% CI) HbA1c treatment difference −0.21 (−0.38, −0.04) (PP population)]; gated superiority assessment showed a statistically significant advantage for LM25 (p = 0.010; ITT population). Mean blood glucose, glycaemic variability, overall tolerability and hypoglycaemic episodes per patient-year did not show significant differences between treatments during the study. Conclusions In patients with type 2 diabetes inadequately controlled on once-daily basal insulin glargine and metformin and/or pioglitazone, intensification with LM25 was superior to a basal–prandial approach in terms of reduction in HbA1c after 24 weeks and did not increase hypoglycaemia episodes.

    The purpose of this investigation was to assess the effectiveness of variable resistance as provided through elastic plus free weight techniques in college aged males and females. Twenty novice lifters were randomly assigned to a traditional free weight only (6 males and 5 females) or elastic band plus free weight group (5 males and 5 females) and 9 more normally active controls (5 males and 4 females), were recruited to maintain normal activity for the duration of the study. No differences existed between control, free weight and elastic band at baseline for age, body height, body mass, body mass index, and body fat percentage. One-repetition maximums were performed for squat and bench press while both strength and power were assessed using isokinetic dynamometry. Elastic groups and free-weight groups completed 24 weeks of whole body, periodized, high intensity resistance (65–95% of one-repetition maximum) training three times/week. Training programs were identical except that the elastic group trained the barbell squat, bench press and stiff-legged deadlift with 20–35% of their total prescribed training loads coming from band resistance (assessed at the top of the range of motion) with the remainder from free weight resistance. A mixed-model analysis revealed that peak torque, average power and one-repetition maximums for squat were significantly greater after training for the elastic group compared to the control (p<0.05). In addition, the free weight group also showed significantly greater improvements over the control in peak torque and one-repetition maximums for squat and bench press. No significant differences were observed between the elastic band and free weight groups. Combined variable elastic band plus free weight exercises are effective at increasing strength and power similar to free-weights alone in novice college aged males and females. However, due to complexity in set-up and load assignment elastic adoption by novice lifters in an

    The purpose of this study was to evaluate the effect of neurofeedback on depressive symptoms and electrophysiological disturbances in patients with major depressive disorder. We recruited participants suffering from depression to evaluate efficacy of left prefrontal beta with alpha/theta training. An 8-week, prospective, open-label study was undertaken. Twenty participants were recruited. The treatment protocol was twice or three times a week training of beta at F3 with alpha/theta at Pz for 8 weeks. When every visit, patients were received beta training for 30 min, and then alpha/theta training for 30 min. Baseline, 4 and 8 week scores of; the Hamilton rating scale for Depression (HAM-D), the Hamilton rating scale for Anxiety (HAM-A), the Beck Depression Inventory (BDI)-II, the Beck Anxiety Inventory (BAI), Clinical global impression-severity (CGI-S), and pre- and post-treatment resting state EEGs were compared. Interhemispheric alpha power asymmetry (A score) was computed for homologous sites F3-F4. Pre- and post-training clinical assessments revealed significant improvements in HAM-D, HAM-A, BDI, and CGI-S scores. Cumulative response rates by HAM-D were 35.0 and 75.0 % at 4 and 8 weeks, respectively, corresponding cumulative remission rates by HAM-D were 15.0 and 55.0 %, respectively. No significant differences were found between pre- and post-treatment A score. Neurofeedback treatment could improve depressive symptoms significantly. In addition, anxiety symptoms and clinical illness severity decreased significantly after neurofeedback treatment. Despite its several limitations, such as, small sample size and lack of a control group, this study suggested neurofeedback has significant effects in patients with major depressive disorder.

    Purpose Intravesical instillation of liposomes is a potentially new therapeutic option for subjects with interstitial cystitis/bladder pain syndrome (IC/BPS). The aim of this study was to explore the safety and clinical outcomes of 4 weekly instillations of sphingomyelin liposomes in an open-label cohort of subjects with IC/BPS. Methods A total of fourteen symptomatic IC/BPS subjects were treated with intravesical liposomes once a week for 4 weeks. Safety measurements included lab specimen collection, vital signs, post void residual (PVR), and assessment of adverse events (AEs). Efficacy measurements included pain visual analog scales (VAS), voiding diaries, global response assessments (GRAs), and O'Leary-Sant Interstitial Cystitis Symptom and Problem Indices (ICSI and ICPI). Results No treatment-related adverse events (AE) were reported at any time over the course of the study. Urgency VAS scores significantly decreased at 4 weeks (p=0.0029) and 8 weeks (p=0.0112) post-treatment. Pain VAS scores significantly decreased at 4 weeks post-treatment (p=0.0073). Combined ICSI and ICPI scores improved significantly at 4 weeks and 8 weeks (p=0.002 for both time points) post-treatment. Responses to GRA showed improvement at 4 weeks post- instillation. No significant decrease in urinary frequency was found. Conclusion Sphingomyelin liposome instillations were well tolerated in subjects with IC/BPS with no AEs attributed to the test article. Treatment was associated with improvements in pain, urinary urgency, and overall symptom scores. Placebo controlled clinical trials are needed to assess this potential therapy for IC/BPS.

    Objective The objective of this study was to assess the long-term safety of linezolid in patients with chronic infections requiring treatment for ≥6 weeks. Enhanced monitoring for optic neuropathy was included to characterize the early development of this side effect and to identify ophthalmologic tests that might be valuable in early detection of this event. Methods This was a multicenter, open-label, pilot study of patients aged ≥18 years on long-term linezolid therapy. Matched control patients were included for baseline assessment comparison. Patients were assessed at study entry, monthly while on treatment, at the end of treatment, and 30 days following the last dose. Aggregate ocular safety data were reviewed. Response to treatment was reported. Results The study was terminated owing to slow enrollment. Twenty-four patients received linezolid; nine patients were included as matched controls. Linezolid was prescribed for a median of 80.5 days (range, 50–254 days). In patients with a reported clinical outcome, the majority were considered improved or cured. Common treatment-related adverse events (AEs) included anemia, peripheral neuropathy, polyneuropathy, vomiting, and asthenia, and were consistent with the known safety profile. Most AEs resolved or stabilized with discontinuation of treatment. Results of ophthalmologic tests in the one case adjudicated as probable linezolid-associated optic neuropathy revealed abnormal color vision, characteristic changes in the optic disk, and central scotomas in each eye. Conclusion In our small population, linezolid was generally well tolerated and AEs were consistent with the known safety profile. Extensive ophthalmologic testing of all 24 linezolid-treated patients identified one case adjudicated as probable, linezolid-associated optic neuropathy. PMID:27621644

    Purpose The circadian rhythm hypothesis of bipolar disorder (BD) suggests a role for melatonin in regulating mood, thus extending the interest toward the melatonergic antidepressant agomelatine as well as type I (acute) or II cases of bipolar depression. Patients and methods Twenty-eight depressed BD-II patients received open label agomelatine (25 mg/bedtime) for 6 consecutive weeks as an adjunct to treatment with lithium or valproate, followed by an optional treatment extension of 30 weeks. Measures included the Hamilton depression scale, Pittsburgh Sleep Quality Index, the Clinical Global Impression Scale–Bipolar Version, Young Mania Rating Scale, and body mass index. Results Intent to treat analysis results demonstrated that 18 of the 28 subjects (64%) showed medication response after 6 weeks (primary study endpoint), while 24 of the 28 subjects (86%) responded by 36 weeks. When examining primary mood stabilizer treatment, 12 of the 17 (70.6%) valproate and six of the 11 (54.5%) lithium patients responded by the first endpoint. At 36 weeks, 14 valproate treated (82.4%) and 10 lithium treated (90.9%) subjects responded. At 36 weeks, there was a slight yet statistically significant (P = 0.001) reduction in body mass index and Pittsburgh Sleep Quality Index scores compared to respective baseline values, regardless of mood stabilizer/outcome. Treatment related drop-out cases included four patients (14.28%) at week 6 two valproate-treated subjects with pseudo-vertigo and drug-induced hypomania, respectively, and two lithium-treated subjects with insomnia and mania, respectively. Week 36 drop outs were two hypomanic cases, one per group. Conclusion Agomelatine 25 mg/day was an effective and well-tolerated adjunct to valproate/lithium for acute depression in BD-II, suggesting the need for confirmation by future double blind, controlled clinical trials.

    Objective Selective serotonin reuptake inhibitors (SSRIs) remain the first-line treatment for posttraumatic stress disorder (PTSD). However, adjunctive atypical antipsychotics are often used to target residual or refractory symptoms. Asenapine is a novel atypical antipsychotic that possesses a high serotonin (5-HT2A) to dopamine (D2) affinity ratio and alpha-adrenergic antagonism, which may be advantageous in treating PTSD. This pilot study aimed to identify the therapeutic potential of asenapine as an adjunctive treatment for PTSD. Method Eighteen subjects initiated treatment in this single-site prospective, open-label, 12-week trial of flexibly-dosed asenapine in Veterans with PTSD who had not responded to an adequate course of treatment with an SSRI, venlafaxine, or mirtazapine. Subjects remained on their antidepressant medication and were started on adjunctive asenapine 5 mg sublingual at bedtime, which was gradually titrated to a maximum of 10 mg twice per day, as tolerated. The primary outcome measure was the Clinician Administered PTSD Scale (CAPS) for DSM-IV. Results Fifteen subjects finished at least 4 weeks and eleven completed the 12 week study. There was a significant and clinically meaningful decrease in CAPS from baseline (77.56 ± 14.48) to week 4 (48.7 ± 30.6), and to week 12 (35.3 ± 19.7). Six participants experienced adverse events possibly related to asenapine; however, only three participants discontinued early due to related adverse events. Conclusion This pilot study demonstrated that adjunctive treatment with asenapine may provide additional benefit to some patients experiencing residual PTSD symptoms in spite of optimal antidepressant therapy. A larger efficacy study may be warranted. PMID:27738377

    Objective: A pilot open label, single dose trial of fenobam, an mGluR5 antagonist, was conducted to provide an initial evaluation of safety and pharmacokinetics in adult males and females with fragile X syndrome (FXS). Methods: Twelve subjects, recruited from two fragile X clinics, received a single oral dose of 50–150 mg of fenobam. Blood for pharmacokinetic testing, vital signs and side effect screening was obtained at baseline and numerous time points for 6 h after dosing. Outcome measures included prepulse inhibition (PPI) and a continuous performance test (CPT) obtained before and after dosing to explore the effects of fenobam on core phenotypic measures of sensory gating, attention and inhibition. Results: There were no significant adverse reactions to fenobam administration. Pharmacokinetic analysis showed that fenobam concentrations were dose dependent but variable, with mean (SEM) peak values of 39.7 (18.4) ng/ml at 180 min after the 150 mg dose. PPI met a response criterion of an improvement of at least 20% over baseline in 6 of 12 individuals (4/6 males and 2/6 females). The CPT did not display improvement with treatment due to ceiling effects. Conclusions: Clinically significant adverse effects were not identified in this study of single dose fenobam across the range of dosages utilised. The positive effects seen in animal models of FXS treated with fenobam or other mGluR5 antagonists, the apparent lack of clinically significant adverse effects, and the potential beneficial clinical effects seen in this pilot trial support further study of the compound in adults with FXS.

    Background Cancer pain is highly prevalent, and existing treatments are often insufficient to provide adequate relief. Objectives We assessed the long-term safety and efficacy of subcutaneous tetrodotoxin treatment in reducing the intensity of chronic cancer-related pain. Methods In this multicentre open-label longitudinal trial, 30 μg tetrodotoxin was administered subcutaneously twice daily for 4 days in a heterogeneous cohort of patients with persistent pain despite opioids and other analgesics. “Responder” was defined as a mean reduction of 30% or more in pain intensity from baseline; and “clinical responder” as some pain reduction, but less than 30%, plus agreement on the part of both the patient and the physician that a meaningful analgesic response to treatment had occurred. Results Of 45 patients who entered the longitudinal trial, 41 had sufficient data for analysis. Of all 45 patients, 21 (47%) met the criteria for “responder” [16 patients (36%)] or “clinical responder” [5 patients (11%)]. Onset of pain relief was typically cumulative over days, and after administration ended, the analgesic effect subsided over the course of a few weeks. No evidence of loss of analgesic effect was observed during subsequent treatments (2526 patient–days in total and a maximum of 400 days in 1 patient). One patient withdrew from the study because of adverse events. Toxicity was usually mild (82%) or moderate (13%), and remained so through subsequent treatment cycles, with no evidence of cumulative toxicity or tolerance. Conclusions Long-term treatment with tetrodotoxin is associated with acceptable toxicity and, in a substantial minority of patients, resulted in a sustained analgesic effect. Further study of tetrodotoxin for moderate-to-severe cancer pain is warranted. PMID:21655148

    A phase III, open-label, long-term clinical study was performed to evaluate the safety and efficacy of pramipexole in a cohort of 141 Japanese patients with primary restless legs syndrome (RLS). The patients were started on pramipexole 0.25 mg/day and were subsequently maintained on that dose or switched to 0.125, 0.5, or 0.75 mg/day to achieve optimal efficacy and tolerability. The International Restless Legs Syndrome Study Group Rating Scale for restless legs syndrome (IRLS) score improved from 22.3+/-4.7 at baseline to 11.1+/-7.7 at week 8 and 4.9+/-5.9 at week 52. IRLS responders, defined as patients whose IRLS total score decreased by > or =50% from baseline, accounted for 67.4% at week 12 and 86.6% at week 52. Over 90% of patients were Clinical Global Impression-global improvement (CGI-I) and Patient Global Impression (PGI) responders. The Pittsburgh Sleep Quality Index (PSQI) score decreased from 7.9+/-3.1 at baseline to 4.6+/-2.9 at week 52. Similarly, the Japanese version of the Epworth Sleepiness Scale score decreased from 9.3+/-5.2 to 4.9+/-3.8. Baseline IRLS score < or =20 was significantly associated with a complete IRLS response in this long-term study. Adverse events were typical of nonergot dopamine agonists, mild in intensity, and decreased in frequency as the study progressed. RLS augmentation was not observed. Pramipexole 0.25-0.75 mg/day is efficacious, safe, and well tolerated in patients with RLS. Pramipexole showed good efficacy, particularly in patients with an IRLS total score <20.

    Purpose This study is the first clinical trial aiming to explore the clinical outcomes in burnout patients treated with Rhodiola rosea. The reported capacity of R. rosea to strengthen the organism against stress and its good tolerability offer a promising approach in the treatment of stress-related burnout. The aim of the treatment was to increase stress resistance, thus addressing the source rather than the symptoms of the syndrome and preventing subsequent diseases associated with a history of burnout. The objective of the trial was to provide the exploratory data required for planning future randomized trials in burnout patients in order to investigate the clinical outcomes of treatment with R. rosea dry extract in this target group. Methods The study was planned as an exploratory, open-label, multicenter, single-arm trial. A wide range of rating scales were assessed and evaluated in an exploratory data analysis to generate hypotheses regarding clinical courses and to provide a basis for the planning of subsequent studies. A total of 118 outpatients were enrolled. A daily dose of 400 mg R. rosea extract (WS® 1375, Rosalin) was administered over 12 weeks. Clinical outcomes were assessed by the German version of the Maslach Burnout Inventory, Burnout Screening Scales I and II, Sheehan Disability Scale, Perceived Stress Questionnaire, Number Connection Test, Multidimensional Mood State Questionnaire, Numerical Analogue Scales for different stress symptoms and impairment of sexual life, Patient Sexual Function Questionnaire, and the Clinical Global Impression Scales. Results The majority of the outcome measures showed clear improvement over time. Several parameters had already improved after 1 week of treatment and continued to improve further up to the end of the study. The incidence of adverse events was low with 0.015 events per observation day. Discussion The trial reported here was the first to investigate clinical outcomes in patients suffering from burnout

    Summary Background Incorporation of a taxane as adjuvant treatment for early breast cancer offers potential for further improvement of anthracycline-based treatment. The UK TACT study (CRUK01/001) investigated whether sequential docetaxel after anthracycline chemotherapy would improve patient outcome compared with standard chemotherapy of similar duration. Methods In this multicentre, open-label, phase III, randomised controlled trial, 4162 women (aged >18 years) with node-positive or high-risk node-negative operable early breast cancer were randomly assigned by computer-generated permuted block randomisation to receive FEC (fluorouracil 600 mg/m2, epirubicin 60 mg/m2, cyclophosphamide 600 mg/m2 at 3-weekly intervals) for four cycles followed by docetaxel (100 mg/m2 at 3-weekly intervals) for four cycles (n=2073) or control (n=2089). For the control regimen, centres chose either FEC for eight cycles (n=1265) or epirubicin (100 mg/m2 at 3-weekly intervals) for four cycles followed by CMF (cyclophosphamide 600 mg/m2, methotrexate 40 mg/m2, and fluorouracil 600 mg/m2 at 4-weekly intervals) for four cycles (n=824). The primary endpoint was disease-free survival. Analysis was by intention to treat (ITT). This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN79718493. Findings All randomised patients were included in the ITT population. With a median follow-up of 62 months, disease-free survival events were seen in 517 of 2073 patients in the experimental group compared with 539 of 2089 controls (hazard ratio [HR] 0·95, 95% CI 0·85–1·08; p=0·44). 75·6% (95% CI 73·7–77·5) of patients in the experimental group and 74·3% (72·3–76·2) of controls were alive and disease-free at 5 years. The proportion of patients who reported any acute grade 3 or 4 adverse event was significantly greater in the experimental group than in the control group (p<0·0001); the most frequent events were neutropenia (937 events vs 797 events

    Objectives To investigate the safety of ofatumumab retreatment in rheumatoid arthritis. Methods Patients with active rheumatoid arthritis participating in two phase III trials (OFA110635 and OFA110634) and a phase II extension trial (OFA111752) received individualised open-label ofatumumab retreatment (700 mg X 2 intravenous infusions two weeks apart) ≥24 weeks following the first course and ≥16 weeks following further courses. Retreatment required evidence of clinical response followed by disease relapse. These studies were prematurely terminated by the sponsor to refocus development on subcutaneous delivery. Due to differences in study designs and populations, data are summarised separately for each study. Results 483 patients (243, 148 and 92 in OFA110635, OFA110634 and OFA111752 respectively) received up to 7 treatment courses of intravenous ofatumumab; cumulative duration of exposure was 463, 182 and 175 patient-years, respectively. Mean time between courses was 17–47 weeks. Ofatumumab induced a profound depletion of peripheral B-lymphocytes. Retreated patients derived benefit based on improvement in DAS28. Adverse events were reported for 93% (226/243), 91% (134/148) and 76% (70/92), serious adverse events for 18% (44/243), 20% (30/148) and 12% (11/92) and serious infections for 3% (8/243), 5% (7/148) and 1% (1/92) of patients in OFA110635, OFA110634 and OFA111752, respectively. The most common adverse events were infusion-related reactions during the first infusion of the first course (48–79%); serious infusion-related reactions were rare (<1% [1/243], 5% [8/148], and 1% [1/92] of patients). Two deaths occurred (fulminant hepatitis B virus infection and interstitial lung disease). Conclusions Ofatumumab was generally well tolerated with no evidence of increased safety risks with multiple retreatments. Serious infections were uncommon and did not increase over time.

    Summary Background Methadone is an effective treatment for opioid dependence. When people who are receiving methadone maintenance treatment for opioid dependence are incarcerated in prison or jail, most US correctional facilities discontinue their methadone treatment, either gradually, or more often, abruptly. This discontinuation can cause uncomfortable symptoms of withdrawal and renders prisoners susceptible to relapse and overdose on release. We aimed to study the effect of forced withdrawal from methadone upon incarceration on individuals’ risk behaviours and engagement with post-release treatment programmes. Methods In this randomised, open-label trial, we randomly assigned (1:1) inmates of the Rhode Island Department of Corrections (RI, USA) who were enrolled in a methadone maintenance-treatment programme in the community at the time of arrest and wanted to remain on methadone treatment during incarceration and on release, to either continuation of their methadone treatment or to usual care—forced tapered withdrawal from methadone. Participants could be included in the study only if their incarceration would be more than 1 week but less than 6 months. We did the random assignments with a computer-generated random permutation, and urn randomisation procedures to stratify participants by sex and race. Participants in the continued-methadone group were maintained on their methadone dose at the time of their incarceration (with dose adjustments as clinically indicated). Patients in the forced-withdrawal group followed the institution’s standard withdrawal protocol of receiving methadone for 1 week at the dose at the time of their incarceration, then a tapered withdrawal regimen (for those on a starting dose >100 mg, the dose was reduced by 5 mg per day to 100 mg, then reduced by 3 mg per day to 0 mg; for those on a starting dose ≤100 mg, the dose was reduced by 3 mg per day to 0 mg). The main outcomes were engagement with a methadone maintenance

    The objective of this study was to assess the long-term safety and efficacy of olanzapine long-acting injection (LAI). A 6-year, single-arm, open-label extension study of olanzapine LAI was conducted at 127 sites in 25 countries. Patients were 18-76 years of age, were diagnosed with schizophrenia or schizoaffective disorder (N=931), and had been previously enrolled in one of three clinical trials of olanzapine LAI. Patients received flexibly dosed (45-405 mg) olanzapine LAI every 2-4 weeks. The mean duration of exposure was ∼3 years. A total of 393 (42.2%) patients completed the study. The mean weight change was +2.1 kg (P<0.001), with 40.6% of patients experiencing 7% or higher weight gain. Treatment-emergent categorical changes occurred in fasting glucose, total cholesterol, and triglyceride levels. Pharmacokinetic analyses revealed no systemic accumulation of olanzapine after long-term treatment. There were 36 occurrences of post-injection delirium/sedation syndrome, all resolving within 72 h. The mean Positive and Negative Syndrome Scale total and subscale scores did not change significantly over the course of the study, indicating clinical stability. Olanzapine LAI appeared effective as a long-term maintenance treatment, with a safety profile generally consistent with the known profile of oral olanzapine, except for injection-related events (including post-injection delirium/sedation syndrome).

  3. A pilot open-label trial of minocycline in patients with autism and regressive features

    2013-01-01

    Background Minocycline is a tetracycline derivative that readily crosses the blood brain barrier and appears to have beneficial effects on neuroinflammation, microglial activation and neuroprotection in a variety of neurological disorders. Both microglial activation and neuroinflammation have been reported to be associated with autism. The study was designed to evaluate the effects of minocycline treatment on markers of neuroinflammation and autism symptomatology in children with autism and a history of developmental regression. Methods Eleven children were enrolled in an open-label trial of six months of minocycline (1.4 mg/kg). Ten children completed the trial. Behavioral measures were collected and cerebrospinal fluid (CSF), serum and plasma were obtained before and at the end of minocycline treatment and were analyzed for markers of neuroinflammation. Results Clinical improvements were negligible. The laboratory assays demonstrated significant changes in the expression profile of the truncated form of brain derived neurotrophic factor (BDNF) (P = 0.042) and hepatic growth factor (HGF) (P = 0.028) in CSF. In serum, the ratio of the truncated BDNF form and α-2 macroglobulin (α-2 M), was also significantly lower (P = 0.028) while the mature BDNF/α-2 M ratio revealed no difference following treatment. Only the chemokine CXCL8 (IL-8) was significantly different (P = 0.047) in serum while no significant changes were observed in CSF or serum in chemokines such as CCL2 (MCP-1) or cytokines such as TNF-α, CD40L, IL-6, IFN-γ and IL-1β when pre- and post-treatment levels of these proteins were compared. No significant pre- and post-treatment changes were seen in the profiles of plasma metalloproteinases, putative targets of the effects of minocycline. Conclusions Changes in the pre- and post-treatment profiles of BDNF in CSF and blood, HGF in CSF and CXCL8 (IL-8) in serum, suggest that minocycline may have effects in the CNS by modulating the

    Objective The aim of this study was to determine whether the risk of early spontaneous preterm delivery (sPTD) in asymptomatic women with a sonographic cervical length ≤15 mm in the mid-trimester changes as a function of gestational age at diagnos Methods This cohort study included 109 asymptomatic patients with a sonographic sonographic cervical length ≤15 mm diagnosed at 14–24 weeks of gestation. Women with a multifetal gestation, cerclage, and those with a cervical dilatation >2 cm were excluded. The study population was stratified by gestational age at diagnosis (<20 weeks vs. 20–24 weeks) and by cervical length (≤10 mm vs. 11–15 mm). The primary outcome variables were PTD <28 and <32 weeks’ gestation and the diagnosis-to-delivery interval. Results 1) The median gestational age at diagnosis of a short cervix before 20 weeks and at 20–24 weeks was 18.9 and 22.7 weeks, respectively; 2) women diagnosed before 20 weeks had a higher rate of sPTD at <28 weeks (76.9% vs. 30.9%; p<0.001) and at <32 weeks (80.8% vs. 48.1%; p=0.004), and a shorter median diagnosis-to-delivery interval (21 vs. 61.5 days, p=0.003) than those diagnosed at 20–24 weeks; 3) The rate of amniotic fluid “sludge” was higher among patients diagnosed at <20 weeks of gestation than those diagnosed between 20 and 24 weeks (92.3% vs. 48.2%;p<0.001). Conclusions Asymptomatic women with a sonographic cervical length ≤15 mm diagnosed before 20 weeks have a dramatic and significantly higher risk of early preterm delivery than women diagnosed at 20–24 weeks. These findings can be helpful to physicians in counseling these patients, and may suggest different mechanisms of disease leading to a sonographic short cervix before or after 20 weeks of gestation.

    2013-01-01

    Background: Recent studies suggest that risperidone long-acting injection (RLAI) may be considered for controlling mood episodes in bipolar disorder patients who have relapsed due to medication nonadherence or failure to respond to standard therapies. Currently, no study has reported the usefulness of RLAI in youths with bipolar disorder. The aim of this study was to evaluate short-term effects of RLAI in the naturalistic treatment of early-onset bipolar disorder and its role in symptomatic remission and adherence to treatment. Method: Nineteen early-onset bipolar disorder outpatients receiving RLAI were observed in a 6-month naturalistic study at the outpatient clinic of the Child and Adolescent Affective Disorders Program at the Institute of Psychiatry of the University of São Paulo, São Paulo, Brazil. All patients met DSM-IV criteria for bipolar disorder. Clinical response to RLAI was evaluated using the Children’s Global Assessment Scale (CGAS) and Clinical Global Impressions scale (CGI) across 3 time periods: index time (T0), 8 weeks after (T1), and 24 weeks after (T2). These subjects were recruited from May 2008 to December 2009. Results: Patients receiving RLAI presented considerable improvement in global functioning (CGAS: T0 = 20.6; T1 = 42.9; and T2 = 49.2) and clinical severity (CGI: T0 = 5.9; T1 = 3.9; and T2 = 3.4). Global CGI mean scores of clinical improvement were 2.2 at T1 and 2.4 at T2. There were no significant changes in laboratory measurements and weight throughout follow-up. Conclusions: RLAI was shown to be an alternative treatment for youths with bipolar disorder failing to respond to prior medication trials or with adherence problems. Further blind, randomized controlled studies are necessary to confirm these initial findings.

    2010-01-01

    Background: The overexcitation of the N-methyl-D-aspartate receptor complex appears to play a critical role in the development of neuropathic pain, and ketamine acts as an antagonist to that receptor. Some publications have reported on the prominent relief of neuropathic pain with intravenous or subcutaneous ketamine infusions or a single-dose intravenous ketamine injection despite adverse effects. Objectives: The primary objective of this study was to determine the analgesic effect of intravenous ketamine infusion therapy for neuropathic pain refractory to conventional treatments. Secondary objectives included identifying the variables related to the analgesic effect and the pain descriptors susceptible to ketamine infusion. Methods: This 2-week, open-label, uncontrolled study was conducted in Korean patients with neuropathic pain recruited from the Samsung Seoul Hospital (Seoul, Republic of Korea) outpatient pain management unit. Patients were required to have a pain severity score >5 (visual analog scale [VAS], where 0 = no pain and 10 = worst pain imaginable) over a period of ≥1 month while on standard treatment. The patients were required to have shown no benefit from standard treatment and no pain relief lasting over 1 month. The ketamine infusion therapy was composed of 3 sessions performed consecutively every other day. Midazolam was administered concomitantly to reduce the occurrence of central nervous system-related adverse events (AEs) secondary to ketamine. Each session was as follows: ketamine 0.2 mg/kg and midazolam 0.1 mg/kg were administered intravenously for 5 minutes as a loading dose, followed by a continuous infusion of ketamine 0.5 mg/kg/h and midazolam 0.025 mg/kg/h for 2 hours. AEs were assessed in the following ways: close monitoring of ECG, blood pressure, oxygen saturation, and evaluating the need for treatment of AEs during infu- sion and until discharge by an attending anesthesiologist; an open question about discomfort at the end of

    Summary Background Because treatment with third-generation cephalosporins is associated with slow clinical improvement and high relapse burden for enteric fever, whereas the fluoroquinolone gatifloxacin is associated with rapid fever clearance and low relapse burden, we postulated that gatifloxacin would be superior to the cephalosporin ceftriaxone in treating enteric fever. Methods We did an open-label, randomised, controlled, superiority trial at two hospitals in the Kathmandu valley, Nepal. Eligible participants were children (aged 2–13 years) and adult (aged 14–45 years) with criteria for suspected enteric fever (body temperature ≥38·0°C for ≥4 days without a focus of infection). We randomly assigned eligible patients (1:1) without stratification to 7 days of either oral gatifloxacin (10 mg/kg per day) or intravenous ceftriaxone (60 mg/kg up to 2 g per day for patients aged 2–13 years, or 2 g per day for patients aged ≥14 years). The randomisation list was computer-generated using blocks of four and six. The primary outcome was a composite of treatment failure, defined as the occurrence of at least one of the following: fever clearance time of more than 7 days after treatment initiation; the need for rescue treatment on day 8; microbiological failure (ie, blood cultures positive for Salmonella enterica serotype Typhi, or Paratyphi A, B, or C) on day 8; or relapse or disease-related complications within 28 days of treatment initiation. We did the analyses in the modified intention-to-treat population, and subpopulations with either confirmed blood-culture positivity, or blood-culture negativity. The trial was powered to detect an increase of 20% in the risk of failure. This trial was registered at ClinicalTrials.gov, number NCT01421693, and is now closed. Findings Between Sept 18, 2011, and July 14, 2014, we screened 725 patients for eligibility. On July 14, 2014, the trial was stopped early by the data safety and monitoring board because S Typhi

    The goal of this open-label trial was to examine the efficacy and safety of a 12-week omega-3 fatty acids supplementation among children suffering with Autism Spectrum Disorders (ASD). A total of 41 children and adolescents aged 7-18 years (36 boys, 5 girls; mean age = 11.66, s.d. = 3.05) diagnosed with ASD participated in the study. At post-treatment, participants showed significant improvements on all subscales of the Social Responsiveness Scale (P < 0.01) and the Social and Attention Problems syndrome scales of the Child Behavior Checklist (P < 0.05). Blood fatty acid levels were significantly correlated with changes in the core symptoms of ASD. Baseline levels of blood fatty acid levels were also predictive of response to the omega-3 treatment. Omega-3 fatty acids supplementation was well-tolerated and did not cause any serious side effects. Our findings lend some preliminary support for the use of omega-3 fatty acids supplementation in addressing ASD. Future randomized controlled trials of omega-3 fatty acids in ASD with blood fatty acid measurements with a larger sample and longer follow-up period is warranted.

    Hepatic cirrhosis is one of the leading causes of death worldwide, especially if complicated by ascites. This chronic condition can be related to the classical disease entity jalodara in Traditional Indian Medicine (Ayurveda). The present paper aims to evaluate the general potential of Ayurvedic therapy for overall clinical outcomes in hepatic cirrhosis complicated by ascites (HCcA). In form of a nonrandomized, uncontrolled, single group, open-label observational clinical study, 56 patients fulfilling standardized diagnostic criteria for HCcA were observed during their treatment at the P. D. Patel Ayurveda Hospital, Nadiad, India. Based on Ayurvedic tradition, a standardized treatment protocol was developed and implemented, consisting of oral administration of single and compound herbal preparations combined with purificatory measures as well as dietary and lifestyle regimens. The outcomes were assessed by measuring liver functions through specific clinical features and laboratory parameters and by evaluating the Child-Pugh prognostic grade score. After 6 weeks of treatment and a follow-up period of 18 weeks, the outcomes showed statistically significant and clinically relevant improvements. Further larger and randomized trials on effectiveness, safety, and quality of the Ayurvedic approach in the treatment of HCcA are warranted to support these preliminary findings. PMID:26339267

    Objectives We investigated the clinical benefits of bright light therapy (BLT) as an adjunct treatment to ongoing psychopharmacotherapy, both in unipolar and bipolar difficult-to-treat depressed (DTD) outpatients. Methods In an open-label study, 31 depressed outpatients (16 unipolar and 15 bipolar) were included to undergo 3 weeks of BLT. Twenty-five completed the treatment and 5-week follow-up. Main outcome measures Clinical outcomes were evaluated by the Hamilton Depression Rating Scale (HDRS). The Snaith–Hamilton Pleasure Scale and the Depression Retardation Rating Scale were used to assess changes in anhedonia and psychomotor retardation, respectively. Results The adjunctive BLT seemed to influence the course of the depressive episode, and a statistically significant reduction in HDRS scores was reported since the first week of therapy. The treatment was well-tolerated, and no patients presented clinical signs of (hypo)manic switch during the overall treatment period. At the end of the study (after 5 weeks from BLT discontinuation), nine patients (36%, eight unipolar and one bipolar) still showed a treatment response. BLT augmentation also led to a significant improvement of psychomotor retardation. Conclusion BLT combined with the ongoing pharmacological treatment offers a simple approach, and it might be effective in rapidly ameliorating depressive core symptoms of vulnerable DTD outpatients. These preliminary results need to be confirmed in placebo-controlled, randomized, double-blind clinical trial on larger samples. PMID:26396517

    Fluvoxamine CR has been reported effective in the short-term (12-wk) treatment of generalized social anxiety disorder (social phobia). Social anxiety disorder (SAD) is, however, a chronic disorder thought to require maintenance treatment. We report on data from the extension phase of a short-term study, in order to explore the efficacy and safety profile of fluvoxamine CR (100-300 mg/d) in the longer-term treatment of this disorder. Adult outpatients with generalized social anxiety disorder (GSAD) at 35 centres in Europe, South Africa, and USA were included in an acute phase study (12 wk). Subjects who demonstrated at least minimal improvement by endpoint (n=112), were offered participation in an extension phase, in which medication was continued for a further 12 wk under double-blind conditions. Efficacy was assessed using the Liebowitz Social Anxiety Disorder Scale (LSAS), the Clinical Global Impression Global Improvement score (CGI-I), the Clinical Global Impressions Severity of Illness score (CGI-S), and the Sheehan Disability Scale (SDS). Safety and tolerability assessments were also performed at regular intervals. Subjects treated with fluvoxamine CR had a numerically greater decrease in LSAS total scores than subjects treated with placebo at endpoint. Analysis of data from baseline (day 1) to endpoint (last observation carried forward) demonstrated that this difference tended towards significance, while severity of illness on the CGI-S and disability on the SDS were significantly lower in the fluvoxamine CR group than in the placebo group. The same trends were observed when only data from weeks 12-24 were included in the analysis; although the magnitude of changes was smaller in the extension phase than in the acute phase, fluvoxamine CR-treated subjects continued to show improvement compared to placebo-treated subjects. Most treatment-emergent signs and symptoms (TESS) were mild to moderate in severity. No unexpected abnormalities were reported on vital signs, electrocardiagrams, or laboratory investigations. These data support the long-term efficacy, safety, and tolerability of fluvoxamine CR in the treatment of GSAD. Given the prevalence, persistence, and disability associated with GSAD, and the relative paucity of long-term treatment studies of SAD, the current dataset provides empirical support for the current clinical consensus that pharmacotherapy of this disorder should be continued beyond the acute phase.

    The aim of this study is to evaluate whether polylactic acid (PLA) microspheres and adipose-derived stromal vascular fraction (SVF) cells have appropriate properties as an injectable bulking agent in urologic field. Forty male Sprague-Dawley rats (2-week-old) were randomized into two groups. A total of 0.05 mL of PLA microsphere suspension and 0.05 mL of PLA microsphere suspension mixed with PKH26-labeled SVF cells were injected into bladder wall in group I and group II, respectively. At 2, 8, 16, and 24 weeks of PLA microspheres injection, the volumes of implants were measured and bladder tissues including implants were analyzed and compared grossly and histologically between groups. The distant organs were examined histologically to determine migration of PLA microspheres. At 24 weeks of implantation, 65-70% of injected volume was maintained and there was no significant difference between groups. In histological analyses, injected PLA microspheres were localized in muscular layer of bladder without infiltration into adjacent layer. From 8 to 16 weeks of injection, hybrid tissues contained collagen and actin were observed between PLA microspheres and these findings were more clear in group II. PHK26-labeled SVF cells were identified by fluorescence microscopy at all time points. There was no migration of PLA microspheres to other organs and no abnormality in weight gain and hematologic values. These results suggest the possibility of PLA microspheres as a potentially useful bulking agent in urologic field. And further investigation is needed to know synergic effect of SVF cells.

    Combining different classes of antihypertensives is more effective for reducing blood pressure (BP) than increasing the dose of monotherapies. The aims of this phase I study were to investigate pharmacokinetic and pharmacodynamic interactions between nebivolol, a vasodilatory β1-selective blocker, and valsartan, an angiotensin II receptor blocker, and to assess safety and tolerability of the combination. This was a single-center, randomized, open-label, multiple-dose, 3-way crossover trial in 30 healthy adults aged 18–45 years. Participants were randomized into 1 of 6 treatment sequences (1:1:1:1:1:1) consisting of three 7-day treatment periods followed by a 7-day washout. Once-daily oral treatments comprised nebivolol (20 mg), valsartan (320 mg), and nebivolol–valsartan combination (20/320 mg). Outcomes included AUC0-τ,ss, Cmax,ss, Tmax,ss, changes in BP, pulse rate, plasma angiotensin II, plasma renin activity, 24-hour urinary aldosterone, and adverse events. Steady-state pharmacokinetic interactions were observed but deemed not clinically significant. Systolic and diastolic BP reduction was significantly greater with nebivolol–valsartan combination than with either monotherapy. The mean pulse rate associated with nebivolol and nebivolol–valsartan treatments was consistently lower than that associated with valsartan monotherapy. A sharp increase in mean day 7 plasma renin activity and plasma angiotensin II that occurred in valsartan-treated participants was significantly attenuated with concomitant nebivolol administration. Mean 24-hour urine aldosterone at day 7 was substantially decreased after combined treatment, as compared with either monotherapy. All treatments were safe and well tolerated. In conclusion, nebivolol and valsartan coadministration led to greater reductions in BP compared with either monotherapy; nebivolol and valsartan lower BP through complementary mechanisms.

    This study aimed to compare the efficacy and safety of liraglutide versus insulin detemir plus sitagliptin in Japanese patients with type 2 diabetes treated with a basal-bolus insulin regimen. In this multicenter, open-label trial, 90 patients whose diabetes had been controlled well or moderately (glycated hemoglobin [HbA1c ] ≤ 7.3%) with basal-bolus insulin regimen were randomly assigned to a liraglutide group or a detemir group and were followed up for 24 weeks. The primary end point was HbA1c change from baseline to 24 weeks. Of the 90 enrolled patients, 82 completed this trial. At 24 weeks, the mean changes in HbA1c from baseline were 0.1% ± 0.9% versus 0.3% ± 0.8% in the liraglutide versus detemir groups, respectively (P = .46). The "overall" satisfaction score for the Diabetes Treatment Satisfaction Questionnaire changed from 25.2 ± 7.4 to 29.9 ± 5.3 (P < .001) and from 26.4 ± 6.1 to 28.3 ± 6.4 (P = .12) in the liraglutide and detemir groups, respectively. Although the mean change difference in HbA1c between both groups was not significant, switching from a basal-bolus insulin regimen to liraglutide once daily improved patient satisfaction levels without loss of glycemic control.

    Background The efficacy of antipsychotics can be evaluated using the dimensional models of schizophrenic symptoms. The D2/D3-selective antagonist amisulpride has shown similar efficacy and tolerability to other atypical antipsychotics. The aim of the present study was to determine the efficacy of amisulpride on the dimensional model of schizophrenic symptoms and tolerability in latin schizophrenic patients. Method Eighty schizophrenic patients were enrolled and 70 completed a prospective open-label 3-month study with amisulpride. The schizophrenic symptoms, psychosocial functioning and side-effects were evaluated with standardized scales. Results The patients showed significant improvement in the five dimensions evaluated. Amisulpride (median final dose 357.1 mg/d) was well-tolerated without treatment-emergent extrapyramidal side-effects. Conclusion Amisulpride showed efficacy on different psychopathological dimensions and was well tolerated, leading to consider this drug a first line choice for the treatment of schizophrenia.

    Levodopa–carbidopa intestinal gel (LCIG) delivered continuously via percutaneous endoscopic gastrojejunostomy (PEG-J) tube has been reported, mainly in small open-label studies, to significantly alleviate motor complications in Parkinson’s disease (PD). A prospective open-label, 54-week, international study of LCIG is ongoing in advanced PD patients experiencing motor fluctuations despite optimized pharmacologic therapy. Pre-planned interim analyses were conducted on all enrolled patients (n = 192) who had their PEG-J tube inserted at least 12 weeks before data cutoff (July 30, 2010). Outcomes include the 24-h patient diary of motor fluctuations, Unified Parkinson’s Disease Rating Scale (UPDRS), Clinical Global Impression-Improvement (CGI-I), Parkinson’s Disease Questionnaire (PDQ-39), and safety evaluations. Patients (average PD duration 12.4 yrs) were taking at least one PD medication at baseline. The mean (±SD) exposure to LCIG was 256.7 (±126.0) days. Baseline mean “Off” time was 6.7 h/day. “Off” time was reduced by a mean of 3.9 (±3.2) h/day and “On” time without troublesome dyskinesia was increased by 4.6 (±3.5) h/day at Week 12 compared to baseline. For the 168 patients (87.5%) reporting any adverse event (AE), the most common were abdominal pain (30.7%), complication of device insertion (21.4%), and procedural pain (17.7%). Serious AEs occurred in 60 (31.3%) patients. Twenty-four (12.5%) patients discontinued, including 14 (7.3%) due to AEs. Four (2.1%) patients died (none deemed related to LCIG). Interim results from this advanced PD cohort demonstrate that LCIG produced meaningful clinical improvements. LCIG was generally well-tolerated; however, device and procedural complications, while generally of mild severity, were common. PMID:23287001

    Background: Whereas many patients respond quickly to treatment with tumour necrosis factor (TNF) inhibitors, some patients may experience significant but delayed responses. Objective: To evaluate the clinical response between 12 and 24 weeks in subjects with rheumatoid arthritis from the Trial of Etanercept and Methotrexate with Radiographic Patient Outcomes. Methods: Clinical response was assessed at 24 weeks in 12-week non-responders, according to American College of Rheumatology (ACR) response criteria. The proportion of subjects who successfully maintained response to 52 weeks was analysed, as were radiographic outcomes. Results: Data from 682 subjects were included in the analysis. Non and partial responders in all three groups (etanercept, methotrexate and etanercept plus methotrexate) at week 12 showed an improvement in responses at week 24. Over 80% of the week 24 ACR20/50/70 responders in the etanercept plus methotrexate arm sustained their response to 52 weeks. In the etanercept arms, a delayed clinical response was not associated with increased radiographic progression at week 52. Conclusion: A significant proportion of non and partial responders to etanercept with or without methotrexate therapy at week 12 achieved a good clinical response or improved their overall clinical response at week 24. Discontinuing TNF inhibitor therapy at 12 weeks may be premature in some rheumatoid arthritis patients. PMID:18535115

    Oral valacyclovir's efficacy and tolerability as suppressive therapy versus episodic therapy were compared for recurrent herpes labialis (RHL). Subjects with a history of at least 3 RHL episodes in the past year were randomized to receive 6 months of oral valacyclovir episodic therapy at the first sign of prodrome (two 2-g doses separated by 12 hours) and 6 months of oral valacyclovir suppressive therapy (1 g once daily) for 6 months in open-label, crossover fashion. The mean +/- SE number of recurrences per 120 days of follow-up (primary endpoint) was lower with suppressive therapy (0.30 +/- 0.41) than episodic therapy (0.71 +/- 0.79) (P < .005). The probability of remaining recurrence free over 6 months was significantly higher with suppressive therapy than episodic therapy. The median time to first recurrence was 81 days with episodic therapy and was not calculable (> 180 days) for suppressive therapy (P = 0.021). Data for secondary efficacy endpoints (pain severity score, mean duration of recurrences, maximal total lesion area) showed approximately a 30% to 50% reduction in mean values with suppressive therapy compared with episodic therapy, but results were statistically significantly different between the regimens for pain severity only. The percentage of subjects with at least one adverse event over 6 months of treatment that was considered to be drug related was 3% with suppressive therapy and 6% with episodic therapy. Suppressive therapy with oral valacyclovir was more effective than episodic therapy with oral valacyclovir in reducing the frequency of recurrences of herpes labialis and prolonging the time to first recurrence and was also similarly well-tolerated.

    This study evaluated the safety and efficacy of a sirolimus, corticosteroid, and cyclosporine reduction regimen in an open-label, 12-month trial of 420 de novo renal allograft recipients at 49 European transplant centers. One month post-transplantation, 357 patients were randomized to receive standard-dose cyclosporine (sCsA, n = 179) or reduced-dose cyclosporine (rCsA, n = 178). All patients also received sirolimus and corticosteroids. The primary end points were the rate of biopsy-confirmed acute rejection (BCAR) and renal function, as measured by serum creatinine. Baseline demographic and donor characteristics were similar between groups. BCAR rates at 12 months were not significantly different: 11.2% for rCsA patients and 16.2% for sCsA patients. Mean serum creatinine (±SEM) was significantly lower (1.75 ± 0.10 vs. 1.97 ± 0.07 mg/dl, P < 0.001), and creatinine clearance (±SEM; Nankivell method) was significantly higher (57.8 ± 1.78 vs. 49.5 ± 2.46 ml/min, P < 0.001) in patients receiving rCsA versus sCsA at 1 year, respectively. Patient and graft survival exceeded 98% in both groups. No significant differences in infection or malignancy were noted between groups. The rCsA with sirolimus and corticosteroid regimen resulted in excellent 12-month patient and graft survival, a low incidence of BCAR, and improved renal function in renal allograft recipients. Sirolimus administered with rCsA and corticosteroids provided adequate immunosuppression while reducing the potential for the nephrotoxic effects of cyclosporine. These findings may help to improve long-term renal allograft outcomes.

    The purpose of the present paper was to investigate the effects of the dopamine agonist amantadine in those patients with weight gain induced by olanzapine. An open trial was conducted in those patients who gained >3 kg in weight induced by olanzapine use. All subjects were evaluated by weight, body mass index (BMI), the Brief Psychiatric Rating Scale (BPRS), and the Extrapyramidal Symptom Rating Scale (ESRS) before and after the use of amantadine in addition to olanzapine. Twenty-five of 30 enrolled patients completed the present study. Mean bodyweight and BMI was increased by 6.44 +/- 4.42 kg and 5.04 +/- 3.47 kg/m2 significantly with olanzapine alone (P < 0.001). When amantadine and olanzapine were used together, the average weight and BMI decreased by 1.07 +/- 3.19 kg and 0.84 +/- 2.5 kg/m2, but did not have statistical significance. The average values of BPRS showed a significant decrease (P < 0.001). No significant changes were present in ESRS. Amantadine did not have an effect on weight gain induced by olanzapine. Randomized placebo-controlled prospective studies are needed.

    OBJECTIVES - To assess the efficacy of topiramate in the treatment of idiopathic intracranial hypertension (IIH) and to compare it with acetazolamide. METHODS - Fourty patients diagnosed as IIH and randomly assigned to treatment with either acetazolamide or topiramate were assessed prospectively. Improvement in the visual fields at the end of third, sixth and twelfth months were taken into consideration. RESULTS - The demographic, clinical features and the cerebrospinal fluid (CSF) pressure of the two treatment groups were similar at the beginning of the study. When the follow-up visual field grades were compared with the visual field grades at the beginning of the study in each group a statistically significant improvement was detected with both drugs. When the results of the two treatment groups were compared with each other no statistically significant difference was present. Prominent weight loss was recorded in the topiramate group. CONCLUSIONS - Topiramate seems to be effective in the treatment of IIH. Weight reduction as well as the reduction of the CSF formation is the possible mechanism of action.

    Abstract Background: Incadronate has been found to lessen the increase in corrected serum calcium levels in malignancy-associated hypercalcemia (MAH) in a Phase III study in Japan. The drug is currently used to treat MAH in Japan. Objective: The purpose of this study was to assess the clinical usefulness of incadronate in patients with MAH. Methods: This open-label study was conducted at 3 medical institutions in Korea. Korean patients with MAH (corrected serum calcium levels ≥11.0 mg/dL) were given a single 10-mg IV infusion of incadronate over 2 to 4 hours in 500 to 1000 mL of normal saline. Corrected calcium levels were determined and subjective symptoms and objective findings (ie, bone pain, spontaneous pain, pain from contusion, tenderness, other pain, loss of appetite, nausea and/or vomiting, thirst, constipation, fatigue, and disturbance of consciousness) were used to monitor the effectiveness of the drug for 6 days after the infusion. Symptoms were evaluated using a 4-point scale (0 = none to 3 = severe). Adverse events (AEs) were identified by patients' reports, and adverse drug events (ADEs) were assessed by the investigators throughout the study. Results: Twenty-four Korean patients (18 [75%]male, 6 [25%]female; mean age, 56.5 years) were included in the study; data from 22 and 24 patients were used to assess effectiveness and tolerability, respectively. Corrected serum calcium level was significantly decreased on day 6 after treatment compared with pretreatment on day 0 (baseline) (9.51 [0.89] mg/dL vs 11.83 [0.89] mg/dL; P < 0.001). The antihypercalcemic effect of incadronate became apparent as an inhibition of bone absorption a few days after infusion. Corrected serum calcium level was significantly decreased on days 2 to 6 (P < 0.001) after treatment compared with pretreatment at baseline. Evaluation of symptoms showed significant improvement in the incadronate-treated group (mean total score [range] at baseline, 8 [1–23] and day 6, 5.5 [1–17

    Background Sodium-glucose cotransporter 2 (SGLT2) inhibitors are novel agents used to treat type 2 diabetic patients. We investigated the efficacy of the SGLT2 inhibitor ipragliflozin on diabetic nephropathy in Japanese patients with type 2 diabetes. Methods A 50 mg dose of ipragliflozin was administered for 24 weeks to 50 patients with type 2 diabetes who were concomitantly managed with diet and exercise therapy alone or antidiabetic medications other than SGLT2 inhibitors. Results At the end of the 24-week ipragliflozin treatment, significant decreases in mean glycated hemoglobin (HbA1c) (1.0±1.2%) and body weight (2.7 ± 2.5 kg) were observed; in addition, median urinary albumin-to-creatinine ratio (UACR) significantly decreased from 15.5 (8.0 - 85.7) to 12.9 (7.4 - 36.3) mg/gCr. Sub-analysis by renal function at baseline revealed that median UACR in patients with estimated glomerular filtration rate (eGFR) ≥ 90 mL/min/1.73 m2 decreased significantly from 12.3 (7.5 - 89.6) to 10.6 (5.8 - 27.3) mg/gCr. Furthermore, mean eGFR decreased significantly from 102.4 ± 8.6 to 93.6 ± 10.5 mL/min/1.73 m2 in these patients. In contrast, UACR and eGFR did not change significantly in patients with eGFR < 90. In addition, analysis of the relationship between the amount of change in UACR and blood pressure at 24 weeks revealed a significant positive correlation between UACR and SBP values, independently of the presence of diabetic nephropathy. Conclusions Our results indicate that ipragliflozin may facilitate HbA1c control and body weight reduction. Furthermore, our results also raise the possibility that ipragliflozin significantly reduces urinary albumin levels and improves glomerular hyperfiltration in a subset of patients with type 2 diabetes.

    Introduction. This is an open-label pilot study on four weeks of virgin coconut oil (VCO) to investigate its efficacy in weight reduction and its safety of use in 20 obese but healthy Malay volunteers. Methodology. Efficacy was assessed by measuring weight and associated anthropometric parameters and lipid profile one week before and one week after VCO intake. Safety was assessed by comparing organ function tests one week before and one week after intake of VCO. Paired t-test was used to analyse any differences in all the measurable variables. Results. Only waist circumference (WC) was significantly reduced with a mean reduction of 2.86 cm or 0.97% from initial measurement (P = .02). WC reduction was only seen in males (P < .05). There was no change in the lipid profile. There was a small reduction in creatinine and alanine transferase levels. Conclusion. VCO is efficacious for WC reduction especially in males and it is safe for use in humans. PMID:22164340

    Background In patients with relapsing-remitting MS (RRMS) fingolimod prevents disease relapses and delays disability progression. First dose administration of fingolimod is associated with a transient, dose-dependent decrease in heart rate (HR) in the 6 hours after drug intake. The aim of the study is to to assess safety and tolerability of the first dose of fingolimod in a cohort of Italian patients with RRMS without alternative therapeutic options. Methods Open-label, single arm, multicentre study. After the first dose of fingolimod, patients were observed for 6 hours and had their vital signs monitored hourly. Extended on-site monitoring was provided when required. Results Of the 906 patients enrolled in the study, most (95.2%) did not experience any adverse event (AE) following fingolimod administration. Cardiovascular AEs occurred in 18 patients and included bradycardia (1.3%), first-and second-degree atrioventricular block (0.1% and 0.2%), palpitations (0.1%), sinus arrhythmia (0.1%) and ventricular premature beats (0.1%). All events were self-limiting and did not require any intervention. Extended monitoring was required in 34 patients. Conclusions These results, in a population who better resembled real-world clinical practice in terms of concomitant diseases and medications, are consistent with previous clinical trials and confirmed that the first dose administration of fingolimod is generally safe and well tolerated.

    A multicenter, open-label study was performed to investigate the safety and tolerability of bosentan in Japanese patients with systemic sclerosis (SSc) and secondary digital ulcers. Twenty-eight patients were enrolled. The safety and tolerability of bosentan was monitored over 52 weeks of study treatment (primary end-point), while incidence and healing of digital ulcers were also assessed up to week 16. The following adverse events occurred in 5% or more of patients during the 52-week treatment period: upper respiratory tract infection (50.0%), abnormal liver function tests (42.9%), digital ulcers (25.0%), anemia (17.9%), peripheral edema (14.3%), diarrhea (10.7%), urinary tract infection (7.1%), arthralgia (7.1%), constipation (7.1%) and herpes zoster (7.1%). Eight patients experienced at least one serious adverse event, including drug-related serious adverse events in two patients, which were abnormal liver function tests and fluid retention (pericardial effusion) in one patient each. During the 16-week observation period, seven out of 28 patients (25%) developed new digital ulcers. In this study, adverse events were comparable with those previously reported with bosentan. Approximately half of the patients had adverse events associated with abnormal liver function tests, thus we conclude that liver function should be monitored regularly during treatment with bosentan.

    Purpose: To determine the effect of low-dose (4 Gy) total skin electron beam therapy as a second-line treatment of Stage IB-II mycosis fungoides in a prospective, open-label study. Methods and Materials: Ten patients (6 men, 4 women, average age 68.7 years [range, 55-82 years]) with histopathologically confirmed mycosis fungoides T2-T4 N0-N1 M0 who did not achieve complete remission or relapsed within 4 months after treatment with psoralen plus ultraviolet-A were included. Treatment consisted of low-dose total skin electron beam therapy administered at a total skin dose of 4 Gy given in 4 fractions over 4 successive days. Results: Two patients had a complete clinical response but relapsed after 3.5 months. Six patients had partial clinical responses, with a mean duration of 2.0 months. One patient had no clinical response. Median time to relapse was 2.7 months. One patient died of unrelated causes and did not complete treatment. Acute side effects included desquamation, xerosis, and erythema of the skin. No severe side effects were observed. Conclusion: Low-dose total skin electron beam therapy can induce complete and partial responses in Stage IB-II mycosis fungoides; however, the duration of remission is short. Low-dose total skin electron beam therapy may find application in palliative treatment of mycosis fungoides because of limited toxicity and the possibility of repeating treatments for long-term disease control.

    Finasteride 1 mg/day is effective in the treatment of androgenetic alopecia (AGA). Our open-label study assessed the efficacy and safety of finasteride for the treatment of Taiwanese men with AGA. We enrolled 34 Taiwanese men (aged 18-40 yr) with AGA of modified Norwood/Hamilton scale (MNHS) grade II-V. In investigator assessments at 12 months, five of 21 subjects (23.8%) had two-grade improvement in MNHS grade and 12 of 21 subjects (57.1%) had one-grade improvement; the others remained at the same grade. In global photographic evaluation, five of 31 subjects (15.1%) had observable hair growth at 6 months and 11 of 21 subjects (52.4%) had observable hair growth at 12 months. Patient self-assessment of hair growth was favorable across all questions in the treatment course, more significantly at 12 months than at 6 months; nine of 21 subjects (42.9%) were satisfied with their overall appearance at 12 months. Serum prostate specific antigen levels had decreased by 23.4% at 12 months. Adverse effects, including abnormal liver function (5/34), were minimal, and the causal relationship with finasteride could not be established. Thus, in Taiwanese men with AGA, finasteride 1 mg/day for 1 year slowed the progression of hair loss and increased hair growth.

    Summary Background Drug treatments for patients with high-risk myelodysplastic syndromes provide no survival advantage. In this trial, we aimed to assess the effect of azacitidine on overall survival compared with the three commonest conventional care regimens. Methods In a phase III, international, multicentre, controlled, parallel-group, open-label trial, patients with higher-risk myelodysplastic syndromes were randomly assigned one-to-one to receive azacitidine (75 mg/m² per day for 7 days every 28 days) or conventional care (best supportive care, low-dose cytarabine, or intensive chemotherapy as selected by investigators before randomisation). Patients were stratified by French–American–British and international prognostic scoring system classifications; randomisation was done with a block size of four. The primary endpoint was overall survival. Efficacy analyses were by intention to treat for all patients assigned to receive treatment. This study is registered with ClinicalTrials.gov, number NCT00071799. Findings Between Feb 13, 2004, and Aug 7, 2006, 358 patients were randomly assigned to receive azacitidine (n=179) or conventional care regimens (n=179). Four patients in the azacitidine and 14 in the conventional care groups received no study drugs but were included in the intention-to-treat efficacy analysis. After a median follow-up of 21·1 months (IQR 15·1–26·9), median overall survival was 24·5 months (9·9–not reached) for the azacitidine group versus 15·0 months (5·6–24·1) for the conventional care group (hazard ratio 0·58; 95% CI 0·43–0·77; stratified log-rank p=0·0001). At last follow-up, 82 patients in the azacitidine group had died compared with 113 in the conventional care group. At 2 years, on the basis of Kaplan-Meier estimates, 50·8% (95% CI 42·1–58·8) of patients in the azacitidine group were alive compared with 26·2% (18·7–34·3) in the conventional care group (p<0·0001). Peripheral cytopenias were the most

    Summary Background The diagnosis and staging of lung cancer is an important process that identifies treatment options and guides disease prognosis. We aimed to assess endobronchial ultrasound-guided transbronchial needle aspiration as an initial investigation technique for patients with suspected lung cancer. Methods In this open-label, multicentre, pragmatic, randomised controlled trial, we recruited patients who had undergone a CT scan and had suspected stage I to IIIA lung cancer, from six UK centres and randomly assigned them to either endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) or conventional diagnosis and staging (CDS), for further investigation and staging. If a target node could not be accessed by EBUS-TBNA, then endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) was allowed as an alternative procedure. Randomisation was stratified according to the presence of mediastinal lymph nodes measuring 1 cm or more in the short axis and by recruiting centre. We used a telephone randomisation method with permuted blocks of four generated by a computer. Because of the nature of the intervention, masking of participants and consenting investigators was not possible. The primary endpoint was the time-to-treatment decision after completion of the diagnostic and staging investigations and analysis was by intention-to-diagnose. This trial is registered with ClinicalTrials.gov, number NCT00652769. Findings Between June 10, 2008, and July 4, 2011, we randomly allocated 133 patients to treatment: 66 to EBUS-TBNA and 67 to CDS (one later withdrew consent). Two patients from the EBUS-TBNA group underwent EUS-FNA. The median time to treatment decision was shorter with EBUS-TBNA (14 days; 95% CI 14–15) than with CDS (29 days; 23–35) resulting in a hazard ratio of 1·98, (1·39–2·82, p<0·0001). One patient in each group had a pneumothorax from a CT-guided biopsy sample; the patient from the CDS group needed intercostal drainage

    Background. The pilot phase IIb VIKING study suggested that dolutegravir (DTG), a human immunodeficiency virus (HIV) integrase inhibitor (INI), would be efficacious in INI-resistant patients at the 50 mg twice daily (BID) dose. Methods. VIKING-3 is a single-arm, open-label phase III study in which therapy-experienced adults with INI-resistant virus received DTG 50 mg BID while continuing their failing regimen (without raltegravir or elvitegravir) through day 7, after which the regimen was optimized with ≥1 fully active drug and DTG continued. The primary efficacy endpoints were the mean change from baseline in plasma HIV-1 RNA at day 8 and the proportion of subjects with HIV-1 RNA <50 c/mL at week 24. Results. Mean change in HIV-1 RNA at day 8 was −1.43 log10 c/mL, and 69% of subjects achieved <50 c/mL at week 24. Multivariate analyses demonstrated a strong association between baseline DTG susceptibility and response. Response was most reduced in subjects with Q148 + ≥2 resistance-associated mutations. DTG 50 mg BID had a low (3%) discontinuation rate due to adverse events, similar to INI-naive subjects receiving DTG 50 mg once daily. Conclusions. DTG 50 mg BID–based therapy was effective in this highly treatment-experienced population with INI-resistant virus.

    Despite the huge health and economic burden of migraine headache, few medications have been approved for its prophylactic treatment, most of which can potentially induce serious adverse effects. Coenzyme Q10 (CoQ10) is a supplement and has shown preliminary benefits in migraine prophylaxis. We aimed to assess this effect in an adult population. This is an open-label, parallel, add-on, match-controlled trial. Eighty patients diagnosed with migraine headache based on International Headache Society criteria were allocated to receiving only their current preventive drugs or their current preventive drugs plus 100 mg CoQ10 daily, matching for their baseline characteristics, and were assessed for frequency and severity of attacks, and ≥50 % reduction in attack frequency per month. Thirty-six and 37 patients were analyzed in CoQ10 and control groups, respectively. Number of attacks per month dropped significantly in the CoQ10 group (mean decrease: 1.6 vs. 0.5 among CoQ10 and control groups, respectively, p < 0.001). A significant reduction was also evident in the severity of headaches (mean decrease: 2.3 vs. 0.6 among CoQ10 and control groups, respectively, p < 0.001). For ≥50 % reduction in the frequency of attacks per month, the number needed to treat was calculated as 1.6. No side effects for CoQ10 were observed. This study suggests that CoQ10 might reduce the frequency of headaches, and may also make them shorter in duration, and less severe, with a favorable safety profile.

    Objective In this open-labeled, 12 weeks follow-up study, we aimed to compare the efficacy and tolerability of agomelatine with sertraline Methods The outpatients of adult psychiatry clinic who have a new onset of depression and diagnosed as ‘major depressive episode’ by clinician according to the Diagnostic and Statistical Manual of Mental Disorders 4th edition and prescribed agomelatine (25 mg/day) or sertraline (50 mg/day) were included in the study. Results The decline of mean Montgomery-Asberg Depression Rating Scale (MADRS) scores of agomelatine group was significantly higher than the sertraline group at the end of 2nd week; however, the difference was not significant at the end of 3 months. Mean Clinical Global Impression-Improvement scale (CGI-I) scores of agomelatine group was lower than sertraline group at first week. Mean CGI-Severity scale and CGI-I scores were favour to sertraline group at the end of the study. Remission rates were 46.7% for sertraline group and 33.3% for agomelatine group while response rates were 76.7% for both groups. Any patient from agomelatine group dropped-out due to adverse effects. The amount of side effects was also less with agomelatine. Conclusion Agomelatine has a rapid onset efficacy on depressive symptoms and this can be beneficial for some critical cases. Considering MADRS scores, agomelatine seems to have similar efficacy with sertraline but we also point the need for long term studies since CGI scores were favour to sertraline group at the end of the study. Agomelatine has a favourable tolerability profile both in terms of discontinuation and the amount of side effects compared to sertraline. PMID:27776387

    Objectives To follow up on the increases we reported in normalized metabolic activity in salience network hubs from a 2-month open label study of memantine in frontotemporal dementia (FTD). Methods We repeated fluoro-deoxyglucose positron emission tomography (PET) after 6 months of drug use and subjected the data to an SPM analysis to reveal clusters of significant change from baseline. We also sought correlations between changes in behavioral disturbances on the Frontal Behavioral Inventory (FBI). Results Recruitment of one progressive nonfluent aphasia and one behavioral variant FTD precluded statistical analysis for any FTD subtype other than semantic dementia. The baseline-to-6-month interval showed increased normalized metabolic activity in the left orbitofrontal cortex (p<0.002) for 5 participants with semantic dementia. The 2–6 month interval revealed a late increase in normalized metabolic activity in the left insula (p<0.013), right insula (p<0.009), and left anterior cingulate (p<0.005). The right anterior cingulate showed both an initial increase and a delayed, further increase (2–6 month, p<0.016). FBI scores worsened by 43.3%. One participant with semantic dementia opted not to continue memantine beyond 2 months yet showed similar FDG-PET increases. Conclusions Increases in normalized cortical metabolic activity in salience network hubs were sustained in SD over a 6-month period. Since one participant without medication also showed these changes, further investigation is recommended through a double-blind, placebo-controlled study with FDG-PET as an outcome measure.

    Sonidegib is a selective inhibitor of Smoothened receptor, which is a key regulator of the Hedgehog signaling pathway. The purpose of this study was to determine the maximum tolerated dose based on dose-limiting toxicity (DLT) and the recommended dose (RD) of sonidegib in Asian patients with advanced solid tumors. This was an open-label, single-arm, multicenter, two-group, parallel, dose-escalation, phase I study undertaken in Asian patients; group 1 included patients from Japan and group 2 included patients from Hong Kong and Taiwan. Dose escalation was guided by a Bayesian logistic regression model dependent on DLTs in cycle 1 and other safety findings. A total of 45 adult Asian patients with confirmed advanced solid tumors were enrolled. Group 1 included 21 patients (12 treated with 400 mg q.d. [once daily] and 9 treated with 600 mg q.d.) and group 2 included 24 patients (12 treated with 400 mg q.d., 8 treated with 600 mg q.d., and 4 treated with 800 mg q.d.). Elevation in creatine kinase was the DLT in both groups. The most common adverse events suspected to be related to sonidegib in both patient groups were increase in creatine kinase levels, myalgia, fatigue, and abnormal hepatic function. The RD of 400 mg q.d. was defined in both groups. Difference in tolerability was noted between the East Asian patients and Western population. The RD in East Asian patients (400 mg q.d.) was lower than in patients from Europe and the USA (800 mg q.d. and 250 mg twice daily). (Registered with Clinicaltrials.gov: NCT01208831.).

    Previous studies have reported that selective serotonin reuptake inhibitors (SSRIs) may induce or exacerbate rapid eye movement (REM) sleep without atonia (RSWA) and increase the risk of developing REM sleep behavior disorder (RBD). However, most of these studies are retrospective and cross-sectional and employed small sample sizes and a mixture of SSRIs. In this 8-week open-label trial of sertraline in depressed patients (n = 31), depressed patients were administered 50mg sertraline at 8 am on the 1st day and subsequently titrated up to a maximum of 200mg/day. All patients underwent repeated video-polysomnography (vPSG) (baseline, 1st day, 14th day, 28th day, and 56th day). Both tonic (submental) and phasic (submental and anterior tibialis) RSWA events were visually counted. Tonic RSWA increased from 3.2 ± 1.8% at baseline to 5.1 ± 2.3% on the 1st day and 10.4 ± 2.7% on the 14th day; after that, measurements were stable until the 56th day. A similar profile was observed for phasic RSWA. The increases in tonic RSWA (r = 0.56, P = 0.004) and phasic RSWA (submental: r = -0.51, P = 0.02; anterior tibialis: r = 0.41, P = 0.04) were correlated with the degree of the prolonging of REM latency. All of RSWAs were not correlated with patients' demographic and clinical characteristics. Sertraline may induce or exacerbate RSWA. In contrast to idiopathic RBD, sertraline-related RSWA had the specific characteristics of being correlated with the degree of the prolonging of REM latency and no predominance of male sex and elder age, suggesting different pathophysiological mechanisms. The antidepressant-related RSWA should be a potential public health problem in the depressed patients.

    Background: Melasma is a common cause of facial hyperpigmentation with significant cosmetic deformity. Although several treatment modalities are available, none is satisfactory. Aim: To compare the therapeutic efficacy and safety of tranexamic acid (TA) microinjections versus tranexamic acid with microneedling in melasma. Materials and Methods: This is a prospective, randomised, open-label study with a sample size of 60; 30 in each treatment arms. Thirty patients were administered with localised microinjections of TA in one arm, and other 30 with TA with microneedling. The procedure was done at monthly intervals (0, 4 and 8 weeks) and followed up for three consecutive months. Clinical images were taken at each visit including modified Melasma Area Severity Index MASI scoring, patient global assessment and physician global assessment to assess the clinical response. Results: In the microinjection group, there was 35.72% improvement in the MASI score compared to 44.41% in the microneedling group, at the end of third follow-up visit. Six patients (26.09%) in the microinjections group, as compared to 12 patients (41.38%) in the microneedling group, showed more than 50% improvement. However, there were no major adverse events observed in both the treatment groups. Conclusions: On the basis of these results, TA can be used as potentially a new, effective, safe and promising therapeutic agent in melasma. The medication is easily available and affordable. Better therapeutic response to treatment in the microneedling group could be attributed to the deeper and uniform delivery of the medication through microchannels created by microneedling.

    Abstract We investigated the efficacy of dietary consumption of Lactobacillus brevis KB290 (KB290) against influenza in humans by a preliminary intervention study on elementary schoolchildren, using a commercially available probiotic drink. Subjects were divided into Groups A and B, and an open-label, parallel-group trial was conducted in two 8-week periods at a 1-month interval in winter 2013/2014. Group A was provided with a bottle of the test drink containing KB290 (about 6 billion colony-forming units) every school day in the first period and had no treatment in the second period, and vice versa for Group B. Epidemic influenza was not observed during the first period and only two of 1783 subjects were diagnosed. In the second period, the incidence of influenza in Groups A (no treatment) and B (provided the test drink) was 23·9 and 15·7%, respectively, and the difference was statistically significant (P < 0·001). The reduction in the incidence of influenza by KB290 consumption was especially remarkable in unvaccinated individuals. This is believed to be the first study to show a probiotic food reducing the incidence of influenza in schoolchildren, although further studies are needed to confirm the effectiveness of the probiotic strain KB290. Significance and Impact of the Study We demonstrated a reduction in the incidence of influenza in 1089 schoolchildren by continual intake of a probiotic drink containing Lactobacillus brevis KB290 (KB290), isolated from a traditional Japanese pickle ‘Suguki’. The effect was especially evident in subjects not inoculated with influenza vaccine. This is believed to be the first report to show reduced incidence of influenza in schoolchildren taking a probiotic food.

    Introduction Early start of an oral diet is safe and beneficial in most types of gastrointestinal surgery and is a crucial part of fast track or enhanced recovery protocols. However, the feasibility and safety of oral intake directly following oesophagectomy remain unclear. The aim of this study is to investigate the effects of early versus delayed start of oral intake on postoperative recovery following oesophagectomy. Methods and analysis This is an open-label multicentre randomised controlled trial. Patients undergoing elective minimally invasive or hybrid oesophagectomy for cancer are eligible. Further inclusion criteria are intrathoracic anastomosis, written informed consent and age 18 years or older. Inability for oral intake, inability to place a feeding jejunostomy, inability to provide written consent, swallowing disorder, achalasia, Karnofsky Performance Status <80 and malnutrition are exclusion criteria. Patients will be randomised using online randomisation software. The intervention group (direct oral feeding) will receive a liquid oral diet for 2 weeks with gradually expanding daily maximums. The control group (delayed oral feeding) will receive enteral feeding via a jejunostomy during 5 days and then start the same liquid oral diet. The primary outcome measure is functional recovery. Secondary outcome measures are 30-day surgical complications; nutritional status; need for artificial nutrition; need for additional interventions; health-related quality of life. We aim to recruit 148 patients. Statistical analysis will be performed according to an intention to treat principle. Results are presented as risk ratios with corresponding 95% CIs. A two-tailed p<0.05 is considered statistically significant. Ethics and dissemination Our study protocol has received ethical approval from the Medical research Ethics Committees United (MEC-U). This study is conducted according to the principles of Good Clinical Practice. Verbal and written informed consent is

    Migraine is a highly prevalent episodic and chronic neurological disorder that impacts otherwise healthy men and women in their most productive years. An anecdotal survey in our clinical practices suggested that milnacipran, a drug indicated for the treatment of fibromyalgia, reduced the incidence of headache in patients with migraine. In this 3-month, open-label, pilot study, 38 patients diagnosed with episodic migraine and 7 patients with chronic migraine maintained headache diaries to assess the effectiveness and tolerability of milnacipran in headache prevention. After a 1-month period to obtain baseline data, milnacipran treatment was initiated and doses were titrated up to 100 mg/day over 1 month. Maintenance therapy continued for an additional 3 months. The primary efficacy end point was change from baseline in the number of all headache days during the last 28 days of maintenance therapy analyzed, using last observation carried forward (LOCF). Change from baseline in migraine days during the last month of the maintenance period using LOCF was a secondary end point. Milnacipran 100 mg daily was associated with a significant reduction in headache (-4.2 days; P < 0.001) and migraine frequency (-2.2 days; P < 0.003). The adverse event profile was consistent with prior reports of milnacipran for the treatment of other conditions. However, compared with the recommended protocol, a more gradual increase in milnacipran dose was required to improve tolerability for some patients. The robust efficacy signal found in this study strongly suggests that a double-blind, placebo-controlled trial of milnacipran in migraine and chronic headache is warranted.

    Sativex is an endocannabinoid system modulator principally containing Δ(9)-tetrahydrocannabinol (THC) and cannabidiol (CBD). During a 6-week randomised controlled trial, Sativex had a clinically relevant effect on spasticity associated with multiple sclerosis (MS). Patients self-titrated oromucosal Sativex to symptom relief or maximum tolerated dose (maximum of 130 mg THC and 120 mg CBD daily). The primary objective was to evaluate the safety and tolerability of long-term treatment by recording the incidence and severity of adverse events (AEs). Secondary outcomes were to determine evidence of developing tolerance and to assess the long-term dosing profile of Sativex. A validated 11-point Numerical Rating Scale of spasticity severity was used to assess efficacy. A total of 146 patients elected to enter this open-label follow-up safety trial. Mean treatment exposure was 334 days (standard deviation, SD = 209 days), and patients administered on average 7.3 (SD = 4.42) actuations per day. Fifty-two (36 %) patients withdrew from the study in the first year, 14 % due to AEs and 9 % due to lack of efficacy. Most AEs were mild/moderate in severity. Common (>10 %) treatment-related AEs were dizziness (24.7 %) and fatigue (12.3 %). Serious AEs occurred in five patients (3.4 %), with two psychiatric events reported by one patient. No psychoses, psychiatric AE trends, or withdrawal symptoms occurred following abrupt cessation of treatment. Baseline symptoms including spasticity did not deteriorate but were maintained to study completion in those patients who did not withdraw. No new safety concerns were identified with chronic Sativex treatment, and serious AEs were uncommon. There was no evidence of tolerance developing, and patients who remained in the study reported continued benefit.

    Background Prolonged-release melatonin (PRM) 2 mg is indicated for insomnia in patients aged 55 years and older. A recent double-blind placebo-controlled study demonstrated 6-month efficacy and safety of PRM in insomnia patients aged 18–80 and lack of withdrawal and rebound symptoms upon discontinuation. Objective To investigate the efficacy, safety, and withdrawal phenomena associated with 6–12 months PRM treatment. Methods Data from a prospective 6–12-month open-label study of 244 community dwelling adults with primary insomnia, who had participated in a placebo-controlled, double-blind dose-ranging trial of PRM. Patients received PRM nightly, followed by a 2-week withdrawal period. Main outcome measures were patient-reported sleep quality ratings (diary), adverse events, vital signs, and laboratory tests recorded at each visit, and withdrawal symptoms (CHESS-84 [Check-list Evaluation of Somatic Symptoms]). Nocturnal urinary 6-sulfatoxymelatonin excretion, a measure of the endogenous melatonin production, was assessed upon discontinuing long-term PRM. Results Of the 244 patients, 36 dropped out, 112 completed 6 months of treatment, and the other 96 completed 12 months of treatment. The mean number of nights by which patients reported sleep quality as “good” or “very good” was significantly higher during PRM than before treatment. There was no evidence of tolerance to PRM. Discontinuation of PRM was not associated with rebound insomnia or withdrawal symptoms; on the contrary, residual benefit was observed. PRM was well tolerated, and there was no suppression of endogenous melatonin production. Conclusion Results support the efficacy and safety of PRM in primary insomnia patients aged 20–80 throughout 6–12 months of continuous therapy. PRM discontinuation even after 12 months was not associated with adverse events, withdrawal symptoms, or suppression of endogenous melatonin production. PMID:21845053

    Purpose To assess the effectiveness and tolerability of cyclosporine ophthalmic emulsion (CsA) 0.05% in patients with moderate to severe dry eye disease in Korea. Methods This was a prospective, multicenter, open-label, surveillance study of 392 Korean patients with moderate to severe dry eye disease who were treated with CsA 0.05% for three months. An assessment of effectiveness was performed at baseline, and after 1, 2, and 3 months. The primary effectiveness outcomes were changes in ocular symptoms and Schirmer score. The secondary effectiveness outcomes were a change in conjunctival staining, use of artificial tears, global evaluation of treatment, and patient satisfaction. The primary safety outcome was the incidence and nature of adverse events. Results A total of 362 patients completed the study. After three months, all ocular symptom scores were significantly reduced compared to the baseline values, while the Schirmer scores were significantly increased relative to baseline (p < 0.0001). After three months, there were significant reductions from baseline in conjunctival staining (p < 0.01) and use of artificial tears (p < 0.0001). According to clinicians' global evaluations, most patients (>50%) experienced at least a 25% to 50% improvement in symptoms from baseline at each follow-up visit. The majority of patients (72.0%) were satisfied with the treatment results, and 57.2% reported having no or mild symptoms after treatment. The most common adverse events were ocular pain (11.0%). Conclusions Our findings indicate that CsA 0.05% is an effective and tolerable treatment for dry eye disease in Korean clinical practice. PMID:22131772

    We investigated the effect of a 24-week energy-restricted intervention with low or high dairy intake (LD or HD) on the metabolic profiles of urine, blood and feces in overweight/obese women by NMR spectroscopy combined with ANOVA-simultaneous component analysis (ASCA). A significant effect of dairy intake was found on the urine metabolome. HD intake increased urinary citrate, creatinine and urea excretion, and decreased urinary excretion of trimethylamine-N-oxide (TMAO) and hippurate relative to the LD intake, suggesting that HD intake was associated with alterations in protein catabolism, energy metabolism and gut microbial activity. In addition, a significant time effect on the blood metabolome was attributed to a decrease in blood lipid and lipoprotein levels due to the energy restriction. For the fecal metabolome, a trend for a diet effect was found and a series of metabolites, such as acetate, butyrate, propionate, malonate, cholesterol and glycerol tended to be affected. Overall, even though these effects were not accompanied by a higher weight loss, the present metabolomics data reveal that a high dairy intake is associated with endogenous metabolic effects and effects on gut microbial activity that potentially impact body weight regulation and health. Moreover, ASCA has a great potential for exploring the effect of intervention factors and identifying altered metabolites in a multi-factorial metabolomic study.

    Onychomycosis is difficult to cure as this requires eradication of the primary infection and protection of new areas of growth from reinfection. A new topical treatment (K101) has been developed. The aim of this study was to assess the efficacy, safety and tolerability of K101 treatment of distal subungual onychomycosis. This was a 24-week (plus 2-week washout), multicentre, randomised, double-blind, placebo-controlled study in 493 patients with distal subungual onychomycosis (K101, n = 346; placebo, n = 147), stratified according to degree of nail involvement. More patients with ≤50% nail involvement achieved the primary endpoint (mycological cure after 26 weeks) in the K101 group (27.2%) than placebo (10.4%; P = 0.0012). Proportions for patients with 51-75% involvement were 19.1% for K101 and 7.0% for placebo (not significant). More patients applying K101 than placebo judged that their condition had improved from week 2 (P = 0.0148) to week 24 (P = 0.0004). No safety issues were identified. K101 provides early visible improvements in nail appearance and a clinically meaningful antifungal activity.

    2013-01-01

    Introduction The long-term safety and therapeutic response of sodium oxybate (SXB) in fibromyalgia syndrome (FM) patients were assessed for a combined period of up to 1 year in a prospective, multicenter, open-label, extension study in patients completing 1 of 2 phase 3 randomized, double-blind, controlled, 14-week trials that examined the efficacy and safety of SXB 4.5 g, SXB 6 g, and placebo for treatment of FM. Methods This extension study comprised an additional 38 weeks of treatment and was carried out at 130 clinical sites in 7 countries. Initial entry criteria for the previous 2 double-blind clinical trials required that patients aged ≥ 18 years met the American College of Rheumatology 1990 criteria for FM, had a body mass index (BMI) < 40 kg/m2, and had a score ≥ 50 on a 100-mm pain visual analog scale (VAS) at baseline. All patients began treatment in the extension study with SXB 4.5 g/night (administered in 2 equally divided doses) for at least 1 week, followed by possible serial 1.5 g/night dose increases to 9 g/night (maximum) or reductions to 4.5 g/night (minimum). Results Of the 560 FM patients enrolled in this extension study, 319 (57.0%) completed the study. The main reason for early discontinuation was adverse events (AEs; 23.0% of patients). Patients were primarily middle-aged (mean 46.9 ± 10.8 years), female (91.1%), white (91.4%), with a mean duration of FM symptoms of 9.9 ± 8.7 years. Serious AEs were experienced by 3.6% of patients. The most frequently reported AEs (incidence ≥ 5% at any dose or overall) were nausea, headache, dizziness, nasopharyngitis, vomiting, sinusitis, diarrhea, anxiety, insomnia, influenza, somnolence, upper respiratory tract infection, muscle spasms, urinary tract infection, and gastroenteritis viral. Maintenance of SXB therapeutic response was demonstrated with continued improvement from controlled-study baseline in pain VAS, Fibromyalgia Impact Questionnaire (FIQ) total scores, and other measures

    Previous studies have focused on the curative effects of memantine in patients with mild-to-moderate frontotemporal lobar degeneration (FTLD); however, its benefits in patients with moderate-to-severe FTLD have not been investigated. The present study explores the behavioral, cognitive and functional effects of memantine on behavioral variant frontotemporal dementia (bvFTD) in patients with mild and moderate-to-severe stage bvFTD. A total of 42 patients with bvFTD completed a 6-month treatment plan of 20 mg memantine daily in an open-label, self-controlled clinical trial. Patients were divided into two groups according to their Mini-Mental State Examination (MMSE) score: Mild (score, 21–26); and moderate-to-severe (score, 4–20). Primary endpoints included Neuropsychiatric Inventory Questionnaire (NPI-Q) and Clinic Dementia Rating (CDR) scores, and secondary endpoints comprised Neuropsychiatric Inventory Caregiver Distress Scale (NPI-D), MMSE, Montreal Cognitive Assessment (MoCA), Activity of Daily Life (ADL) and Hamilton Depression Rating Scale (HAMD) scores. Memantine treatment had no effect on overall NPI-Q scores, with the exception of the agitation subdomain in all patients with bvFTD. However, patients with moderate-to-severe bvFTD exhibited a better performance than patients with mild bvFTD, demonstrated by improved NPI-Q total scores and subscales of agitation, depression, apathy and disinhibition. In the moderate-to-severe group, CDR and HAMD scores remained stable, but MMSE, MoCA and ADL scores were reduced after 6 months of treatment. Memantine was well-tolerated in patients. In conclusion, patients with moderate-to-severe bvFTD responded significantly better to memantine in comparison to patients with mild bvFTD with regard to their neuropsychiatric scores, while memantine did not present any cognitive or functional benefits in patients with mild bvFTD. A randomized, double-blind, placebo-controlled clinical trial with a larger number of patients is

    Background Ivacaftor, approved for treatment of cystic fibrosis (CF) patients aged ≥6 years with G551D-CFTR or other gating mutations, was evaluated in subjects with R117H-CFTR, a residual function mutation. Methods A 24 week, placebo-controlled, double-blind, randomized clinical trial (RCT) enrolled 69 CF subjects aged ≥6 years with R117H-CFTR and percent predicted forced expiratory volume in 1 second (ppFEV1) ≥40. Primary outcome was absolute change from baseline in ppFEV1 through week 24. Secondary outcomes included sweat chloride, CF Questionnaire-Revised (CFQ-R) respiratory domain, and safety. An open-label extension enrolled 65 RCT subjects after washout; after 12 weeks, an interim analysis was performed. Findings After 24 weeks, treatment difference in mean absolute change in ppFEV1 between ivacaftor (n=34) and placebo (n=35) was 2.1 percentage points (p=0·20). Ivacaftor treatment resulted in significant RCT treatment differences in sweat chloride (−24.0 mmol/L; p<0.001) and CFQ-R respiratory domain (8.4; p=0.009). In prespecified subgroup analyses, ppFEV1 significantly improved with ivacaftor in subjects aged ≥18 years (treatment difference vs placebo: 5.0 percentage points; p=0.01), but not in subjects aged 6 to 11 years (−6.3 percentage points; p=0.03). In the extension study, both placebo/ivacaftor and ivacaftor/ivacaftor groups showed ppFEV1 improvement (absolute change from postwashout baseline at week 12: 5.5 percentage points; p<0.0001). No new safety concerns were identified. Interpretation Although this RCT did not meet the primary outcome, secondary outcomes and subgroup analyses suggest that ivacaftor significantly improves lung function in adult patients with R117H-CFTR and may benefit patients with established disease.

    Introduction Hochuekkito, a traditional herbal medicine, is occasionally prescribed in Japan to treat patients with a poor general condition. We aimed to examine whether this medicine was beneficial and tolerable for patients with progressed pulmonary Mycobacterium avium complex (MAC) disease. Methods This pilot open-label quasi-randomized controlled trial enrolled 18 patients with progressed pulmonary MAC disease who had initiated antimycobacterial treatment over one year ago but were persistently culture-positive or intolerant. All patients continued their baseline treatment regimens with (n = 9) or without (n = 9) oral Hochuekkito for 24 weeks. Results Baseline characteristics were generally similar between the groups. Most patients were elderly (median age 70 years), female, had a low body mass index (<20 kg/m2), and a long-term disease duration (median approximately 8 years). After the 24-week treatment period, no patient achieved sputum conversion. Although the number of colonies in sputum tended to increase in the control group, it generally remained stable in the Hochuekkito group. Radiological disease control was frequently observed in the Hochuekkito group than the control group (8/9 vs. 3/9; p = 0.05). Patients in the Hochuekkito group tended to experience increase in body weight and serum albumin level compared with those in the control group (median body weight change: +0.4 kg vs. −0.8 kg; median albumin change: +0.2 g/dl vs. ±0.0 g/dl). No severe adverse events occurred. Conclusions Hochuekkito could be an effective, feasible adjunct to conventional therapy for patients with progressed pulmonary MAC disease. Future study is needed to explore this possibility. Trial Registration UMIN Clinical Trials Registry UMIN000009920 PMID:25093868

    Background Interleukin-1 plays a pivotal role in in the pathogenesis of systemic juvenile idiopathic arthritis (sJIA). We assessed the efficacy and safety of rilonacept (IL-1 trap), an IL-1 inhibitor, in a randomized, double-blind, placebo-controlled trial. Methods An initial 4-week double-blind placebo phase was incorporated into a 24-week randomized multi-center design, followed by an open label phase. We randomized 71 children with at least 2 active joints 1:1 to 2 arms of the study. Patients in the rilonacept arm received rilonacept (4.4mg/kg loading dose followed by 2.2mg/kg weekly, subcutaneously) from day 0; patients in the placebo arm received placebo for 4 weeks followed by a loading dose of rilonacept at week 4 followed by weekly maintenance doses. The primary endpoint was time to response, using adapted JIA ACR30 response criteria coupled with absence of fever and taper of systemic corticosteroids using pre-specified criteria. Results Time to response was shorter in the rilonacept arm than in the placebo arm (Chi-square 7.235, P=.007). Secondary analysis showed 20/35 (57%) of patients in the rilonacept arm responded at week 4 compared to 9/33 (27%) in the placebo arm (P=.016) using the same response criteria. Exacerbation of sJIA (4) was the most common SAE. More patients in the rilonacept arm had elevated liver transaminases, including more than three times the upper limits of normal, as compared to those in the placebo arm. Adverse events were similar in the two arms of the study. Conclusions Rilonacept was generally well tolerated and demonstrated efficacy in active sJIA. PMID:24839206

Adult patients with T2DM, inadequately controlled with metformin monotherapy, (850 mg bid), participated in this 24-week, multicenter, observational study. Patients were enrolled in two cohorts: vildagliptin/metformin fixed-dose combination (group A) and vildagliptin metformin free-dose combination (group B). Results. 659 patients were enrolled, 360 were male, with mean BMI 30.1, mean T2DM duration 59.6 months, and mean HbA1c at baseline 8%; 366 patients were assigned to group A and 293 to group B; data for 3 patients was missing. In group A, 98.9% of patients were compliant with their treatment compared to 84.6% of group B. The odds ratio for compliance in group A versus B was (OR) 18.9 (95% CI: 6.2, 57.7; P < 0.001). In group A mean HbA1c decreased from 8.1% at baseline to 6.9% (P < 0.001) at the study end and from 7.9% to 6.8% (P < 0.001) in group B. Conclusions. Patients in group A were more compliant than patients in group B. These results are in accordance with international literature suggesting that fixed-dose combination therapies lead to increased compliance to treatment.

    Abstract Objective: The purpose of this study was to evaluate the long-term safety and efficacy of risperidone in treating irritability and related behaviors in children and adolescents with autistic disorders. Methods: In this 6 month (26 week) open-label extension (OLE) study, patients (5–17 years of age, who completed the previous fixed-dose, 6 week, double-blind [DB] phase) were flexibly dosed with risperidone based on body weight. The maximum allowed dose was 1.25 mg/day for those weighing 20 to <45 kg, and 1.75 mg/day for those weighing ≥45 kg. The study primarily assessed risperidone's safety; efficacy was assessed as a secondary end-point. Results: Fifty-six (71%) out of 79 enrolled patients completed the OLE; the most common discontinuations were for insufficient response (7 [9%]) or adverse events (AE) (5 [6%]). The most common (≥5% frequency in the total group) AEs were increased appetite (11% [n=9]); increased weight and vomiting (9% [n=7] each); sedation, pyrexia, and upper respiratory tract infection (8% [n=6] each); nasopharyngitis (6% [n=5]); and somnolence and fatigue (5% [n=4] each). Extrapyramidal AEs were reported in 6 (8%) patients. Increase in mean weight (11–15%) and body mass index (5–10%) occurred; one patient discontinued because of weight increase. One potentially prolactin-related AE (irregular menstruation) was reported. The risperidone high-dose group had the greatest mean improvement in sleep visual analog scale (24.6). All groups showed additional improvement in efficacy scale scores during the OLE. Conclusions: During this OLE, safety findings with risperidone treatment (maximum weight-based dose of 1.25 mg/day or 1.75 mg/day) were consistent with those observed in the DB phase, and with the current safety information for risperidone in autistic, psychiatric, and behavioral disorders. Patients experienced some additional improvement in irritability and related behaviors. Clinical Trials Registry: This phase-4

    The purpose of this study was to assess the safety and efficacy of doxorubicin-loaded beads (DC Beads) delivered by transarterial embolization for the treatment of unresectable hepatocellular carcinoma (HCC). This open-label, single-center, single-arm study included 62 cirrhotic patients with documented single unresectable HCC. Mean tumor diameter was 5.6 cm (range, 3-9 cm) classified as Okuda stages 1 (n = 53) and 2 (n = 9). Patients received repeat embolizations with doxorubicin-loaded beads every 3 months (maximum of three). The maximum doxorubicin dose was 150 mg per embolization, loaded in DC Beads of 100-300 or 300-500 {mu}m. Regarding efficacy, overall, an objective response according to the European Association for the Study of the Liver criteria was observed in 59.6%, 81.8%, and 70.8% across three treatments. A complete response was observed in 4.8% after the first procedure and 3.6% and 8.3% after the second and third procedures, respectively. At 9 months a complete response was seen in 12.2%, an objective response in 80.7%, progressive disease in 6.8%, and 12.2% showed stable disease. Mean tumor necrosis ranged from 77.4% to 83.9% (range, 28.6%-100%) across three treatments. {alpha}-Fetoprotein levels showed a mean decrease of 1123 ng/ml (95% CI = 846-1399; p = 3 x 10{sup -11}) after the first session and remained stable after the second and third embolizations (42 and 70 ng/ml decrease, respectively). Regarding safety, bilirubin, {gamma}-glutamyl transferase, aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase showed only transient increases during the study period. Severe procedure-related complications were seen in 3.2% (cholecystitis, n 1; liver abscess, n = 1). Postembolization syndrome was observed in all patients. We conclude that hemoembolization using doxorubicin-loaded DC Beads is a safe and effective treatment of HCC as demonstrated by the low complication rate, increased tumor response, and sustained reduction of

    This open-label, fixed-sequence, phase 1 study evaluated the pharmacokinetic interaction between maraviroc (MVC) and ritonavir-boosted fosamprenavir (FPV/r) in healthy subjects. In period 1, subjects received 300 mg of MVC twice daily (BID; cohort 1) or once daily (QD; cohort 2) for 5 days. In period 2, cohort 1 subjects received 700/100 mg of FPV/r BID alone on days 1 to 10 and then FPV/r at 700/100 mg BID plus MVC at 300 mg BID on days 11 to 20; cohort 2 subjects received FPV/r at 1,400/100 mg QD alone on days 1 to 10 and then FPV/r at 1,400/100 mg QD plus MVC at 300 mg QD on days 11 to 20. Pharmacokinetic parameters, assessed on day 5 of period 1 and on days 10 and 20 of period 2, included the maximum plasma concentration (Cmax), the concentration at end of dosing interval (Cτ), and the area under the curve over dosing interval (AUCτ). Safety and tolerability were also assessed. MVC geometric mean AUCτ, Cmax, and Cτ were increased by 149, 52, and 374%, respectively, after BID dosing with FPV/r, and by 126, 45, and 80%, respectively, after QD dosing. Amprenavir (the active form of the prodrug fosamprenavir) and ritonavir exposures were decreased in the presence of MVC with amprenavir AUCτ, Cmax, and Cτ decreased by 34 to 36% in the presence of FPV/r plus maraviroc BID and by 15 to 30% with FPV/r plus MVC QD both compared to FPV/r alone. The overall all-causality adverse-event (AE) incidence rate was 96.4%; all AEs were of mild or moderate severity. Commonly reported treatment-related AEs (>20% of patients overall) included diarrhea, fatigue, abdominal discomfort, headache, and nausea. No serious AEs or deaths occurred. In summary, maraviroc exposure increased in the presence of FPV/r, whereas MVC coadministration decreased amprenavir and ritonavir exposures. MVC dosed at 300 mg BID with FPV/r is not recommended due to concerns of lower amprenavir exposures; however, no dose adjustment is warranted with MVC at 150 mg BID in combination with FPV/r based on

    Abstract Background: This study was conducted to evaluate the safety and tolerability, and population pharmacokinetics (PPK) of montelukast as well as efficacy in the treatment of perennial allergic rhinitis (PAR) in paediatric Japanese patients aged between 1 and 15 years. Methods: In this multi-centre, open-label trial, 87 paediatric Japanese patients with PAR received montelukast 4 mg oral granules (OG) for 4 weeks (1–5-year-olds, N = 15), 4 mg OG for 12 weeks (1–5-year-olds, N = 36), 5 mg chewable tablets (CT) for 12 weeks (6–9-year-olds, N = 18), or 5 mg CT for12 weeks (10–15-year-olds, N = 18). Clinical exams and laboratory assessments were conducted at study visits, and adverse events (AE) were monitored throughout the study up to 14 days after the last visit. Population pharmacokinetic approach was used to estimate AUC0–∞, Cmax, Tmax and apparent elimination half-life in each age group. Efficacy was assessed based on global evaluations by the subject’s caregiver. Results: There were no serious AEs and one discontinuation due to an AE. The most common AEs in any of the treatment groups were nasopharyngitis, pharyngitis, and acute sinusitis. Montelukast exposure (AUC0–∞) was similar in the 1–5-year-old group and the 6–9-year-old group, but 19% lower in the 10–15-year-old group. Among all patients, the total proportion of patients whose global evaluation was “very much better” was 5.7% (week 2), 11.5% (week 4), and 16.9% (week 12) reflecting improvement in symptoms over time. Conclusion: Montelukast was generally well tolerated in Japanese children with PAR. AUC0–∞was similar in 1–5 and 6–9-year-olds, while a lower exposure was observed in the 10–15-year-old group likely due to differences in bodyweight. The exposure in Japanese paediatric patients was generally consistent with that in non-Japanese paediatric and adult patients. As assessed by the patients’ caregivers, montelukast also

    Motor complications in Parkinson's disease (PD) are associated with long-term oral levodopa treatment and linked to pulsatile dopaminergic stimulation. l-dopa-carbidopa intestinal gel (LCIG) is delivered continuously by percutaneous endoscopic gastrojejunostomy tube (PEG-J), which reduces l-dopa-plasma–level fluctuations and can translate to reduced motor complications. We present final results of the largest international, prospective, 54-week, open-label LCIG study. PD patients with severe motor fluctuations (>3 h/day “off” time) despite optimized therapy received LCIG monotherapy. Additional PD medications were allowed >28 days post-LCIG initiation. Safety was the primary endpoint measured through adverse events (AEs), device complications, and number of completers. Secondary endpoints included diary-assessed off time, “on” time with/without troublesome dyskinesia, UPDRS, and health-related quality-of-life (HRQoL) outcomes. Of 354 enrolled patients, 324 (91.5%) received PEG-J and 272 (76.8%) completed the study. Most AEs were mild/moderate and transient; complication of device insertion (34.9%) was the most common. Twenty-seven (7.6%) patients withdrew because of AEs. Serious AEs occurred in 105 (32.4%), most commonly complication of device insertion (6.5%). Mean daily off time decreased by 4.4 h/65.6% (P < 0.001). On time without troublesome dyskinesia increased by 4.8 h/62.9% (P < 0.001); on time with troublesome dyskinesia decreased by 0.4 h/22.5% (P = 0.023). Improvements persisted from week 4 through study completion. UPDRS and HRQoL outcomes were also improved throughout. In the advanced PD population, LCIG's safety profile consisted primarily of AEs associated with the device/procedure, l-dopa/carbidopa, and advanced PD. LCIG was generally well tolerated and demonstrated clinically significant improvements in motor function, daily activities, and HRQoL sustained over 54 weeks. © 2014 The Authors.

    Background Maintaining and improving physical functioning is key to mitigating the cycle of deconditioning associated with chronic obstructive pulmonary disease (COPD). We evaluated the impact of free combination of the long-acting anticholinergic tiotropium plus the long-acting β2-agonist olodaterol on physical functioning in a real-world clinical setting. Methods In this open-label noninterventional study, Global initiative for chronic Obstructive Lung Disease (GOLD) B–D patients with COPD aged ≥40 years were treated for 4–6 weeks with either tiotropium 5 μg + olodaterol 5 μg (both via Respimat® inhaler) or tiotropium 18 μg (HandiHaler®) + olodaterol 5 μg (Respimat®) once daily. Physical functioning was assessed by the self-reported 10-item Physical Functioning Questionnaire (PF-10). The primary end point was the percentage of patients achieving therapeutic success, defined as a 10-point increase in the PF-10 between baseline (visit 1) and weeks 4–6 (visit 2). Secondary end points included absolute PF-10 scores, Physicians’ Global Evaluation, satisfaction with Respimat® and adverse events. Results A total of 1,858 patients were treated: 1,298 (69.9%) with tiotropium 5 μg + olodaterol 5 μg and 560 (30.1%) with tiotropium 18 μg + olodaterol 5 μg. At study end, 1,683 (92.6%) and 1,556 patients (85.6%) continued using tiotropium and olodaterol, respectively; 48.9% (95% confidence interval: 46.5, 51.3) achieved the primary end point. Therapeutic success rates were significantly higher for maintenance-naïve patients compared to those who had received prior therapy (59.1% vs 44.5%; P<0.0001), largely driven by maintenance-treatment-naïve GOLD B (59.8%) and C (63.0%) patients. Absolute physical functioning scores increased from an average baseline of 44.0 (standard deviation: 25.2) to 54.2 (standard deviation: 26.9) at visit 2. Patients’ general condition improved from baseline to visit 2, and patients were largely satisfied with the Respimat

    Summary Background Supplementary immunisation activities with oral poliovirus vaccines (OPVs) are usually separated by 4 week intervals; however, shorter intervals have been used in security-compromised areas and for rapid outbreak responses. We assessed the immunogenicity of monovalent type-1 oral poliovirus vaccine (mOPV1) given at shorter than usual intervals in Karachi, Pakistan. Methods This was a multicentre, randomised, controlled, four-arm, open-label, non-inferiority trial done at five primary health-care centres in low-income communities in and around Karachi, Pakistan. Eligible participants were healthy newborn babies with a birthweight of at least 2.5 kg, for whom informed consent was provided by their parent or guardian, and lived less than 30 km from the study clinic. After receiving a birth dose of trivalent OPV, we enrolled and randomly assigned newborn babies (1:1:1:1) to receive two doses of mOPV1 with an interval of 1 week (mOPV1–1 week), 2 weeks (mOPV1–2 weeks), or 4 weeks (mOPV1–4 weeks) between doses, or two doses of bivalent OPV (bOPV) with an interval of 4 weeks between doses (bOPV–4 weeks). We gave the first study dose of OPV at age 6 weeks. We did the randomisation with a centrally generated, computerised allocation sequence with blocks of 16; participants’ families and study physicians could not feasibly be masked to the allocations. Trial participants were excluded from local supplementary immunisation activities during the study period. The primary outcome was non-inferiority (within a 20% margin) between groups in seroconversion to type-1 poliovirus. The primary and safety analyses were done in the per-protocol population of infants who received all three doses of vaccine. This trial is registered with ClinicalTrials.gov, number NCT01586572, and is closed to new participants. Findings Between March 1, 2012, and May 31, 2013, we enrolled 1009 newborn babies, and randomly assigned 829 (82%) to treatment. 554 (67%) of the 829

    Abstract Objective The purpose of this study was to describe the safety, tolerability, and efficacy of quetiapine monotherapy continued for up to 26-weeks in youth with schizophrenia or bipolar I disorder. Methods Medically healthy boys and girls with a baseline Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV-TR) diagnosis of schizophrenia (ages 13–17 years) or a manic episode of bipolar I disorder (ages 10–17 years) who participated in one of two acute, double-blind, placebo-controlled studies of immediate-release quetiapine were potentially eligible to enroll in a 26-week, open-label study. During the open-label study, quetiapine was flexibly dosed at 400–800 mg/day, with options to reduce dosing to 200 mg/day based on tolerability. Safety and tolerability outcomes assessed from open-label baseline to week 26 included adverse events (AEs), metabolic/laboratory parameters, extrapyramidal symptoms, suicidality, and vital signs. Results Of 381 patients enrolled in the open-label study (n=176, schizophrenia; n=205, bipolar disorder diagnosis), 237 patients (62.2%) completed the 26-week study period (71.0%, schizophrenia; 54.6%, bipolar disorder). The most common AEs reported during the study included somnolence, headache, sedation, weight increase, and vomiting. A total of 14.9% of patients experienced a shift to potentially clinically significant low levels of high-density lipoprotein cholesterol and 10.2% of patients experienced a shift to potentially clinically significant high triglyceride levels. Weight gain ≥7% was reported in 35.6% of patients between open-label baseline and final visit. After adjustment for normal growth, 18.3% of study participants experienced clinically significant weight gain (i.e., increase in body mass index ≥0.5 standard deviations from baseline). Conclusions In this 26-week study, quetiapine flexibly dosed at 400–800 mg/day, with options to reduce dosing based on tolerability, was generally safe

    Abstract: This open-label, multinational, pilot study randomized (1:2 ratio) adults with HIV-1 RNA <40 copies per milliliter and nucleos(t)ide-related safety/tolerability issues to switch to ritonavir-boosted atazanavir (ATV/r) plus tenofovir disoproxil fumarate/emtricitabine (n = 37) or the nucleos(t)ide reverse transcriptase inhibitor-sparing regimen of ATV/r plus raltegravir (RAL) (n = 72). At 24 weeks, 35/37 (94.6%) and 58/72 (80.6%) of patients, respectively, maintained virological suppression, the primary endpoint, and 1 (2.7%) and 7 (9.7%), respectively, experienced virological rebound. Corresponding 48-week proportions were 86.5%, 69.4%, 2.7%, and 12.5%, respectively. Adherence was lower and treatment discontinuation was higher with ATV/r+RAL. In conclusion, switching to ATV/r+RAL resulted in a higher virological rebound rate than switching to ATV/r plus tenofovir disoproxil fumarate/emtricitabine. PMID:26605505

    Background Non-nucleoside reverse transcriptase (NNRTI) inhibitor-based antiretroviral therapy is not suitable for all treatment-naïve HIV-infected persons. Objective Perform a rigorous evaluation of three NNRTI-sparing initial antiretroviral regimens to demonstrate equivalence for virologic efficacy and tolerability. Design Phase-III, 1:1:1 randomized, open label, >96 week study. Setting Fifty-seven sites in United States and Puerto Rico. Patients Treatment naïve, ≥18 years, HIV-1 RNA >1000 copies/mL, no nucleoside reverse transcriptase or protease inhibitor resistance. Intervention Atazanavir 300 mg with ritonavir 100 mg, daily; or raltegravir 400 mg twice daily; or darunavir 800 mg with ritonavir 100 mg, daily; plus emtricitabine 200 mg + tenofovir disoproxil fumarate 300 mg daily. Measurements Virologic failure defined as confirmed HIV-1 RNA >1000 copies/mL between 16 and 24 weeks, or >200 copies/mL at or after 24 weeks; tolerability failure defined as discontinuation of atazanavir, raltegravir or darunavir for toxicity. A secondary endpoint was a combination of virologic efficacy and tolerability. Results Among 1,809 participants all pairwise comparisons of incidence of virologic failure over 96-weeks demonstrated equivalence within ±10%. Raltegravir and ritonavir-boosted darunavir were equivalent for tolerability, whereas ritonavir-boosted atazanavir resulted in a 12.7% and a 9.2% higher incidence of tolerability discontinuation than raltegravir and ritonavir-boosted darunavir respectively, primarily due to hyperbilirubinemia. For combined virologic efficacy and tolerability ritonavir-boosted darunavir was superior to ritonavir-boosted atazanavir, and raltegravir was superior to both protease inhibitors. Antiretroviral resistance at time of virologic failure was rare but more likely with raltegravir. Limitations Open label; ritonavir not provided Conclusions Over 2 years all three regimens attain high and equivalent rates of virologic control. Regimens

    Summary Background The zoonotic parasite Plasmodium knowlesi has become the most common cause of human malaria in Malaysia and is present throughout much of southeast Asia. No randomised controlled trials have been done to identify the optimum treatment for this emerging infection. We aimed to compare artesunate–mefloquine with chloroquine to define the optimum treatment for uncomplicated P knowlesi malaria in adults and children. Methods We did this open-label, randomised controlled trial at three district hospitals in Sabah, Malaysia. Patients aged 1 year or older with uncomplicated P knowlesi malaria were randomly assigned, via computer-generated block randomisation (block sizes of 20), to receive oral artesunate–mefloquine (target dose 12 mg/kg artesunate and 25 mg/kg mefloquine) or chloroquine (target dose 25 mg/kg). Research nursing staff were aware of group allocation, but allocation was concealed from the microscopists responsible for determination of the primary endpoint, and study participants were not aware of drug allocation. The primary endpoint was parasite clearance at 24 h. Analysis was by modified intention to treat. This study is registered with ClinicalTrials.gov, number NCT01708876. Findings Between Oct 16, 2012, and Dec 13, 2014, we randomly assigned 252 patients to receive either artesunate–mefloquine (n=127) or chloroquine (n=125); 226 (90%) patients comprised the modified intention-to-treat population. 24 h after treatment, we recorded parasite clearance in 97 (84% [95% CI 76–91]) of 115 patients in the artesunate–mefloquine group versus 61 (55% [45–64]) of 111 patients in the chloroquine group (difference in proportion 29% [95% CI 18·0–40·8]; p<0·0001). Parasite clearance was faster in patients given artesunate–mefloquine than in those given chloroquine (18·0 h [range 6·0–48·0] vs 24·0 h [6·0–60·0]; p<0·0001), with faster clearance of ring stages in the artesunate–mefloquine group (mean time to 50% clearance

    Open-label extensions [studies SP516 (NCT00501969) and SP715 (NCT00594386)] of the CLEOPATRA-PD and PREFER studies were conducted to evaluate the safety, tolerability and efficacy of the dopaminergic agonist, rotigotine, over several years of follow-up in patients with advanced Parkinson's disease (PD). Eligible subjects completing the double-blind trials received open-label adjunctive rotigotine (≤16 mg/24 h) for up to 4 and 6 years in Studies SP516 and SP715, respectively. Safety and tolerability were assessed using adverse events, vital signs and laboratory parameters, and efficacy assessed using the unified Parkinson's disease rating scale (UPDRS). Of the 395 and 258 patients enrolled in the SP516 and SP715 studies, 48 and 45 % completed, respectively. Adverse events were typically dopaminergic effects [e.g., somnolence (18-25 %/patient-year), insomnia (5-7 %/patient-year), dyskinesias (4-8 %/patient-year) and hallucinations (4-8 %/patient-year)], or related to the transdermal application of a patch (application site reactions: 14-15 %/patient-year). There were no clinically relevant changes in vital signs or laboratory parameters in either study. Mean UPDRS part II (activities of daily living) and part III (motor function) total scores improved from double-blind baseline during dose titration, then gradually declined over the maintenance period. In study SP516, mean UPDRS part II and III total scores were 0.8 points above and 2.8 points below double-blind baseline, respectively, at end of treatment. In study SP715, mean UPDRS part II and III total scores were 4.1 points above and 0.2 points below baseline, respectively, at end of treatment. In these open-label studies, adjunctive rotigotine was efficacious with an acceptable safety and tolerability profile in patients with advanced PD for up to 6 years.

    Currently, there are limited published data evaluating the effects of tics on serotonin reuptake inhibitor (SRI) monotherapy responses in treating obsessive-compulsive disorder (OCD). One retrospective case-controlled analysis of OCD patients treated with SRI monotherapy showed lesser improvement in OCD symptoms in patients with tics than those without. However, more recently there were preliminary reports of OCD subjects treated with SRI monotherapy which did not demonstrate poorer response in subjects with tics or Tourette's Syndrome (TS). The specific aim of this study was to investigate whether the presence of comorbid chronic tics affected "clinically meaningful improvement" [McDougle, C.J., Goodman, W.K., Leckman, J.F., Barr, L.C., Heninger, G.R., Price, L.H., 1993. The efficacy of fluvoxamine in obsessive-compulsive disorder: effects of comorbid chronic tic disorder. Journal of Clinical Psychopharmacology 13, 354-358] of OCD in an 8-week open-label trial of fluoxetine monotherapy. Seventy-four adult subjects (13 patients with comorbid chronic tics and 61 patients without tics) with a primary DSM-IV OCD diagnosis were treated with up to 40mg fluoxetine for 8 weeks and had at least one post-baseline evaluation. The results indicate that there was a significant response by time in both fluoxetine-with-tic subjects and fluoxetine-without-tic subjects. Additionally, there were 3 (23.0%) OCD subjects with tics who had clinically meaningful improvement versus 16 (26.2%) OCD subjects without tics that demonstrated similar levels of improvement. These findings indicate that OCD patients with or without chronic tic disorders did not have a differential response to an 8-week open-label trial of fluoxetine. Limitations include the relatively low number of tic subjects and the open-label nature of the study. Additional data are needed on how comorbid tics may affect SRI treatment response in OCD.

    Summary Background Randomised placebo-controlled trials have shown that daily oral pre-exposure prophylaxis (PrEP) with tenofovir–emtricitabine reduces the risk of HIV infection. However, this benefit could be counteracted by risk compensation in users of PrEP. We did the PROUD study to assess this effect. Methods PROUD is an open-label randomised trial done at 13 sexual health clinics in England. We enrolled HIV-negative gay and other men who have sex with men who had had anal intercourse without a condom in the previous 90 days. Participants were randomly assigned (1:1) to receive daily combined tenofovir disoproxil fumarate (245 mg) and emtricitabine (200 mg) either immediately or after a deferral period of 1 year. Randomisation was done via web-based access to a central computer-generated list with variable block sizes (stratified by clinical site). Follow-up was quarterly. The primary outcomes for the pilot phase were time to accrue 500 participants and retention; secondary outcomes included incident HIV infection during the deferral period, safety, adherence, and risk compensation. The trial is registered with ISRCTN (number ISRCTN94465371) and ClinicalTrials.gov (NCT02065986). Findings We enrolled 544 participants (275 in the immediate group, 269 in the deferred group) between Nov 29, 2012, and April 30, 2014. Based on early evidence of effectiveness, the trial steering committee recommended on Oct 13, 2014, that all deferred participants be offered PrEP. Follow-up for HIV incidence was complete for 243 (94%) of 259 patient-years in the immediate group versus 222 (90%) of 245 patient-years in the deferred group. Three HIV infections occurred in the immediate group (1·2/100 person-years) versus 20 in the deferred group (9·0/100 person-years) despite 174 prescriptions of post-exposure prophylaxis in the deferred group (relative reduction 86%, 90% CI 64–96, p=0·0001; absolute difference 7·8/100 person-years, 90% CI 4·3–11·3). 13 men (90% CI 9–23

    The objective of this study was to determine the appropriate dose of artesunate for use in a fixed dose combination therapy with chlorproguanil−dapsone (CPG−DDS) for the treatment of uncomplicated falciparum malaria. Methods Open-label clinical trial comparing CPG−DDS alone or with artesunate 4, 2, or 1 mg/kg at medical centers in Blantyre, Malawi and Farafenni, The Gambia. The trial was conducted between June 2002 and February 2005, including 116 adults (median age 27 years) and 107 children (median age 38 months) with acute uncomplicated Plasmodium falciparum malaria. Subjects were randomized into 4 groups to receive CPG–DDS alone or plus 4, 2 or 1 mg/kg of artesunate once daily for 3 days. Assessments took place on Days 0−3 in hospital and follow-up on Days 7 and 14 as out-patients. Efficacy was evaluated in the Day 3 per-protocol (PP) population using mean time to reduce baseline parasitemia by 90% (PC90). A number of secondary outcomes were also included. Appropriate artesunate dose was determined using a pre-defined decision matrix based on primary and secondary outcomes. Treatment emergent adverse events were recorded from clinical assessments and blood parameters. Safety was evaluated in the intent to treat (ITT) population. Results In the Day 3 PP population for the adult group (N = 85), mean time to PC90 was 19.1 h in the CPG−DDS group, significantly longer than for the +artesunate 1 mg/kg (12.5 h; treatment difference −6.6 h [95%CI −11.8, −1.5]), 2 mg/kg (10.7 h; −8.4 h [95%CI −13.6, −3.2]) and 4 mg/kg (10.3 h; −8.7 h [95%CI −14.1, −3.2]) groups. For children in the Day 3 PP population (N = 92), mean time to PC90 was 21.1 h in the CPG−DDS group, similar to the +artesunate 1 mg/kg group (17.7 h; −3.3 h [95%CI −8.6, 2.0]), though the +artesunate 2 mg/kg and 4 mg/kg groups had significantly shorter mean times to PC90 versus CPG−DDS; 14.4 h (treatment difference −6.4 h [95%CI −11.7, −1.0]) and 12.8 h (−7

    Abstract Objectives. To evaluate the long-term efficacy and safety of certolizumab pegol (CZP) plus methotrexate treatment and to assess the efficacy of two CZP maintenance dosing schedules in Japanese rheumatoid arthritis (RA) patients with an inadequate response to methotrexate. Methods. J-RAPID double-blind patients were entered into an open-label extension (OLE) study. Patients withdrawn due to lack of efficacy at 16 weeks and double-blind completers without a week-24 American College of Rheumatology (ACR) 20 response received CZP 200 mg every other week (Q2W) plus methotrexate. Double-blind completers with week-24 ACR20 responses were randomized to CZP 200 mg Q2W plus methotrexate or CZP 400 mg every 4 weeks plus methotrexate. Results. The ACR20/ACR50/ACR70 response rates of double-blind completers (n = 204) were 89.7%/67.2%/36.3% at OLE entry and 95.6%/84.8%/58.3% at 52 weeks, respectively. Other clinical, functional and radiographic outcomes were sustained with long-term CZP plus methotrexate. Long-term treatment with CZP was well-tolerated with no new unexpected adverse events observed. The efficacy and safety of CZP treatment were similar between the two dosing schedules. Conclusions. Continued CZP administration with methotrexate maintained efficacy over 52 weeks and was well-tolerated for Japanese RA patients. No obvious differences in clinical efficacy and safety were observed between the two dosing schedules, giving flexibility in maintenance administration schedules. PMID:24593170

    Background Needle-free delivery improves the immunogenicity of DNA vaccines but is also associated with more local reactogenicity. Here we report the first comparison of Biojector and needle administration of a candidate rAd5 HIV vaccine. Methods Thirty-one adults, 18–55 years, 20 naive and 11 prior rAd5 vaccine recipients were randomized to receive single rAd5 vaccine via needle or Biojector IM injection at 1010 PU in a Phase I open label clinical trial. Solicited reactogenicity was collected for 5 days; clinical safety and immunogenicity follow-up was continued for 24 weeks. Results Overall, injections by either method were well tolerated. There were no serious adverse events. Frequency of any local reactogenicity was 16/16 (100%) for Biojector compared to 11/15 (73%) for needle injections. There was no difference in HIV Env-specific antibody response between Biojector and needle delivery. Env-specific antibody responses were more than 10-fold higher in subjects receiving a booster dose of rAd5 vaccine than after a single dose delivered by either method regardless of interval between prime and boost. Conclusions Biojector delivery did not improve antibody responses to the rAd5 vaccine compared to needle administration. Homologous boosting with rAd5 gene-based vectors can boost insert-specific antibody responses despite pre-existing vector-specific immunity.

    Objectives.  This study aims to assess the safety and efficacy of long-term intrathecal (IT) ziconotide infusion. Materials and Methods.  In this prospective study, 155 patients with severe chronic pain (48 with malignant pain, 107 with nonmalignant pain) who had been responsive to short-term IT ziconotide in a double-blind, placebo-controlled study received long-term, open-label IT ziconotide monotherapy. Efficacy assessments included the mean percentage change on the visual analog scale of pain intensity from baseline in the study of origin; safety was monitored by adverse event (AE) reports, periodic laboratory tests, and vital sign measurements. Results.  At the last available observation, the visual analog scale of pain intensity scores had decreased by a mean of 36.9% from baseline in the short-term trial (N = 144; 95% CI: 30.1-43.7%; p < 0.0001). The mean IT ziconotide dose remained stable over 12 months in the 31 patients who participated in the study for ≥ one year. Ziconotide-related AEs were reported in 147 out of 155 patients (94.8%); 39.4% of patients discontinued treatment because of AEs, the majority of which were considered ziconotide related. Conclusions.  Ziconotide IT monotherapy provided patients with analgesia for 12 months in this open-label study, with an acceptable benefit/risk profile and no evidence of tolerance.

    Long-term (up to 8 years of exposure) safety and efficacy of the antiepileptic drug lacosamide was evaluated in this open-label extension trial (SP615 [ClinicalTrials.gov identifier: NCT00552305]). Patients were enrolled following participation in a double-blind trial or one of two open-label trials of adjunctive lacosamide for partial-onset seizures. Dosage adjustments of lacosamide (100-800 mg/day) and/or concomitant antiepileptic drugs were allowed to optimize tolerability and seizure reduction. Of the 370 enrolled patients, 77%, 51%, and 39% had >1, >3, or >5 years of lacosamide exposure, respectively. Median lacosamide modal dose was 400mg/day. Common treatment-emergent adverse events (TEAEs) were dizziness (39.7%), headache (20.8%), nausea (17.3%), diplopia (17.0%), fatigue (16.5%), upper respiratory tract infection (16.5%), nasopharyngitis (16.2%), and contusion (15.4%). Dizziness (2.2%) was the only TEAE that led to discontinuation in >2% of patients. Ranges for median percent reductions in seizure frequency were 47-65%, and those for ≥ 50% responder rates were 49-63% for 1-, 3-, and 5-year completer cohorts. Exposure to lacosamide for up to 8 years was generally well tolerated, with a safety profile similar to previous double-blind trials, and efficacy was maintained.

    Background: This study assessed the efficacy and safety of briakinumab, a human anti-IL-12/23p40 monoclonal antibody, compared with placebo for the induction and maintenance of remission in patients with moderately to severely active Crohn's disease. Methods: In this phase 2b, multicenter, double-blind, parallel group study, 246 patients stratified by prior tumor necrosis factor–antagonist use and response, were randomized (1:1:1:3) to 4 intravenous induction regimens: placebo, 200, 400, or 700 mg briakinumab, at weeks 0/4/8. At week 12, responders in the placebo or 400-mg induction groups entered the maintenance phase with the same regimen, whereas responders in the 700-mg induction group were rerandomized (1:1:1) to receive placebo, 200, or 700 mg briakinumab at weeks 12/16/20. At week 24, patients in remission stopped receiving study drug (withdrawal phase) until relapse. Patients experiencing relapse, nonresponders, and nonremitters could enter the open-label phase. Results: The primary end point of clinical remission at week 6 was not met. There were numerically greater rates of remission and response at 6, 12, or 24 weeks in patients treated with briakinumab. The safety and tolerability profile of briakinumab was similar in the induction and maintenance phases of the trial. Conclusions: Briakinumab showed a similar safety and tolerability profile to placebo in the induction and maintenance phases, and comparable rates of serious adverse events, adverse events leading to discontinuation, and malignancy. These data provide support for the potential efficacy of briakinumab and other IL-12/23 inhibitors in the treatment of moderate-to-severe Crohn's disease. PMID:25989338

    The study's primary objective was to compare the pharmacokinetics (PK) and pharmacodynamics (PD) of single subcutaneous (SC) or intramuscular (IM) 300-mg doses of natalizumab with IV 300-mg doses of natalizumab in patients with multiple sclerosis (MS). Secondary objectives included investigation of the safety, tolerability, and immunogenicity of repeated SC and IM natalizumab doses. DELIVER was a 32-week, open-label, multicenter study of natalizumab-naive patients with relapsing-remitting MS (RRMS) or secondary progressive MS (SPMS) randomized to receive 300 mg natalizumab by SC injection, IM injection, or IV infusion. PK and PD were evaluated over 8 weeks after the first natalizumab treatment (Part 1) and over 24 weeks with repeated dosing every 4 weeks, beginning at week 8 (Part 2). Seventy-six patients (24 with RRMS and 52 with SPMS) were enrolled in DELIVER. Following SC or IM administration of natalizumab, peak serum concentrations were approximately 40% of those observed with IV administration and showed no major differences in elimination characteristics. Mean bioavailability relative to IV administration was 57.1% to 71.3% with SC administration and 48.7% with IM administration; mean trough serum concentrations were similar with SC or IV administration and lower with IM administration. Following single or multiple doses of natalizumab, PD response was comparable across administration routes and disease stages. No meaningful differences were observed across administration groups in the incidence or nature of overall adverse events, serious adverse events, administration site reactions, hypersensitivity reactions, or antinatalizumab antibodies. These findings support the comparability of PD measures of natalizumab administered IV, SC, or IM.

    Objective. To compare the modifications in lipids between patients with rheumatoid arthritis (RA) receiving etanercept plus methotrexate (ETA + MTX) versus methotrexate (MTX) and their relationship with serum levels of tumor necrosis factor-alpha (TNF-α). Methods. In an observational cohort study, we compared changes in lipid levels in patients receiving ETA + MTX versus MTX in RA. These groups were assessed at baseline and at 4 and 24 weeks, measuring clinical outcomes, total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, and TNF-α. Results. Baseline values for lipid levels were similar in both groups. HDL-C levels increased significantly only in the ETA + MTX group (from 45.5 to 50.0 mg/dL at 4 weeks, a 10.2% increase, P < 0.001, and to 56.0 mg/dL at 24 weeks, a 25.1% increase, P < 0.001), while other lipids underwent no significant changes. ETA + MTX also exhibited a significant increase in TNF-α (44.8 pg/mL at baseline versus 281.4 pg/mL at 24 weeks, P < 0.001). The MTX group had no significant changes in lipids or TNF-α. Significant differences in HDL-C between groups were observed at 24 weeks (P = 0.04) and also in TNF-α  (P = 0.01). Conclusion. HDL-C levels increased significantly following treatment with ETA + MTX, without a relationship with decrease of TNF-α. PMID:25243145

    Proteinuria is an established risk factor for diabetic nephropathy. Recent studies indicate that some xanthine oxidase inhibitors have a renoprotective effect. The aim of this study was to assess whether topiroxostat reduces albuminuria in hyperuricemic patients with diabetic nephropathy and overt proteinuria. The ETUDE study is an ongoing 24-week, multicenter, open-label, randomized (1:1), parallel group study involving hyperuricemic patients with diabetic nephropathy (estimated glomerular filtration rate [eGFR] ≥ 20 mL/min/1.73 m(2)) and overt proteinuria (0.3 ≤ urine protein to creatinine ratio (UPCR) < 3.5 g/g Cr). Patients are randomly assigned to high dose (topiroxostat 160 mg daily) or low dose (topiroxostat 40 mg daily) on top of standard of care. The primary endpoint is the change in albuminuria indicated by urine albumin-to-creatinine ratio after 24 treated weeks relative to the baseline values. This trial was registered at the Japanese University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR: UMIN 000015403). The background, rationale, and study design of this trial are presented here. Seventy-six patients from four registered facilities have already been enrolled and received at least one dose of topiroxostat. This trial will end in 2017. The ETUDE trial is the first randomized controlled study of topiroxostat in hyperuricemic patients with diabetic nephropathy and overt proteinuria. We will clarify the pleiotropic function of topiroxostat including an anti-albumiuric effect as well as its effects on safely decreasing serum uric acid levels.

    ABSTRACT Exposure to environmental toxins is a 21st century global health problem that is often the result of dietary intake. Although efforts are made to reduce dietary toxin levels, they are often unsuccessful, warranting research into novel methods to reduce host exposure. Food-grade microbes that can be delivered to the gastrointestinal tract and that are capable of sequestering toxins present a safe and cost-effective intervention. We sought to investigate the potential for probiotic-supplemented yogurt to lower heavy metal levels in at-risk populations of pregnant women and in children in Mwanza, Tanzania, and to examine the microbiome in relation to toxin levels. Two populations suspected to have high toxic metal exposures were studied. A group of 44 school-aged children was followed over 25 days, and 60 pregnant women were followed over their last two trimesters until birth. A yogurt containing 1010 CFU Lactobacillus rhamnosus GR-1 per 250 g was administered, while control groups received either whole milk or no intervention. Changes in blood metal levels were assessed, and the gut microbiomes of the children were profiled by analyzing 16S rRNA sequencing via the Ion Torrent platform. The children and pregnant women in the study were found to have elevated blood levels of lead and mercury compared to age- and sex-matched Canadians. Consumption of probiotic yogurt had a protective effect against further increases in mercury (3.2 nmol/liter; P = 0.035) and arsenic (2.3 nmol/liter; P = 0.011) blood levels in the pregnant women, but this trend was not statistically significant in the children. Elevated blood lead was associated with increases in Succinivibrionaceae and Gammaproteobacteria relative abundance levels in stool. PMID:25293764

    Exposure to environmental toxins is a 21st century global health problem that is often the result of dietary intake. Although efforts are made to reduce dietary toxin levels, they are often unsuccessful, warranting research into novel methods to reduce host exposure. Food-grade microbes that can be delivered to the gastrointestinal tract and that are capable of sequestering toxins present a safe and cost-effective intervention. We sought to investigate the potential for probiotic-supplemented yogurt to lower heavy metal levels in at-risk populations of pregnant women and in children in Mwanza, Tanzania, and to examine the microbiome in relation to toxin levels. Two populations suspected to have high toxic metal exposures were studied. A group of 44 school-aged children was followed over 25 days, and 60 pregnant women were followed over their last two trimesters until birth. A yogurt containing 10(10) CFU Lactobacillus rhamnosus GR-1 per 250 g was administered, while control groups received either whole milk or no intervention. Changes in blood metal levels were assessed, and the gut microbiomes of the children were profiled by analyzing 16S rRNA sequencing via the Ion Torrent platform. The children and pregnant women in the study were found to have elevated blood levels of lead and mercury compared to age- and sex-matched Canadians. Consumption of probiotic yogurt had a protective effect against further increases in mercury (3.2 nmol/liter; P = 0.035) and arsenic (2.3 nmol/liter; P = 0.011) blood levels in the pregnant women, but this trend was not statistically significant in the children. Elevated blood lead was associated with increases in Succinivibrionaceae and Gammaproteobacteria relative abundance levels in stool. Importance: Probiotic food produced locally represents a nutritious and affordable means for people in some developing countries to counter exposures to toxic metals. Further research and field trials are warranted to explore this approach in countries where communities are located near mining sites and agricultural areas, two types of areas where toxins are likely to be elevated.

    Nutritional interventions have shown varied efficacy on cognitive performance during Alzheimer's disease (AD). Twenty-four individuals diagnosed with AD received a nutraceutical formulation (NF: folate, alpha-tocopherol, B12, S-adenosyl methioinine, N-acetyl cysteine, acetyl-L-carnitine) under open-label conditions (ClinicalTrials.gov NCT01320527). Primary outcome was cognitive performance. Secondary outcomes were behavioral and psychological symptoms of dementia (BPSD) and activities of daily living. Participants maintained their baseline cognitive performance and BPSD over 12 months. These findings are consistent with improvement in cognitive performance and BPSD in prior placebo-controlled studies with NF, and contrast with the routine decline for participants receiving placebo.

    Abstract Objectives: The purpose of this study was to assess long-term improvement in quality of life (QOL) in adolescents with attention-deficit/hyperactivity disorder (ADHD) treated with lisdexamfetamine dimesylate (LDX). Methods: Adolescents with ADHD treated for ≥3 weeks in a 4 week, placebo-controlled study entered a 1 year, open-label study. After the 4 week dose optimization (30, 50, and 70 mg/day LDX) period, treatment was maintained for 48 additional weeks. Change from baseline (of prior study) to week 52/early termination (ET) (of open-label study) in ADHD Rating Scale IV (ADHD-RS-IV) assessed effectiveness, and the Youth QOL-Research Version (YQOL-R) assessed participant-perceived QOL. Post-hoc analyses described effectiveness and QOL for participants with self-perceived poor QOL at baseline (≥1 SD below the mean) versus all others, and for study completers versus study noncompleters. Results: These post-hoc analyses included 265 participants. Participants with baseline self-perceived poor QOL (n=32) versus all others (n=232) exhibited robust YQOL-R perceptual score changes (improvement) with LDX, emerging by week 28 and maintained to week 52/ET. Week 52/ET mean change score ranged from +9.8 to +17.6 for participants with baseline self-perceived poor QOL and +0.4 to +5.1 for all others; week 52/ET improvements in ADHD-RS-IV total scores were similar, regardless of baseline YQOL-R total score. At week 52/ET, study completers had greater YQOL-R improvements than did noncompleters; ADHD-RS-IV total score changes were also numerically larger at week 52/ET for completers than for noncompleters. Conclusion: Participant-perceived QOL and ADHD symptoms improved from baseline with LDX in adolescents with ADHD; greatest improvements occurred among participants with baseline self-perceived poor QOL.

    This randomised, open-label, non-inferiority study was designed to demonstrate that a 3-day course of oral azithromycin 1 g once daily was at least as effective as a standard 7-day course of oral amoxicillin-clavulanate 875/125 mg twice daily in the treatment of outpatients with community-acquired pneumonia (Fine class I and II). In total, 267 patients with clinically and radiologically confirmed community-acquired pneumonia were randomly assigned to receive either the azithromycin (n=136) or the amoxicillin-clavulanate (n=131) regimen. At screening, 60/136 (58.8%) and 61/131 (62.9%) respectively had at least one pathogen identified by sputum culture, PCR, or serology. The primary endpoint was the clinical response in the intent-to-treat population at the end of therapy (day 8 to 12). Clinical success rates were 126/136 (92.6%) for azithromycin and 122/131 (93.1%) for amoxicillin-clavulanate (treatment difference: - 0.48%; 95% confidence interval: - 5.66%; 4.69%). Clinical and radiological success rates at follow-up (day 22-26) were consistent with the end of therapy results, no patient reporting clinical relapse. Bacteriological success rates at the end of therapy were 32/35 (91.4%) for azithromycin and 30/33 (90.9%) for amoxicillin-clavulanate (treatment difference: 0.52%; 95% confidence interval - 10.81%; 11.85%). Both treatment regimens were well tolerated: the overall incidence of adverse events was 34/136 (25.0%) for azithromycin and 22/132 (16.7%) for amoxicillin-clavulanate. In both treatment groups, the most commonly reported events were gastrointestinal symptoms. Azithromycin 1g once daily for 3 days is at least as effective as amoxicillin-clavulanate 875/125 mg twice daily for 7 days in the treatment of adult patients with community-acquired pneumonia.

    Aims/Introduction Canagliflozin is a sodium–glucose cotransporter 2 inhibitor under development for the treatment of type 2 diabetes. Our aim was to examine its efficacy and safety as monotherapy or in combination with commonly used oral antihyperglycemic drugs in Japanese patients with type 2 diabetes. Materials and Methods Patients on diet/exercise alone or diet/exercise plus an oral antihyperglycemic drug (sulfonylurea, glinide, α-glucosidase inhibitor, biguanide, thiazolidinedione or dipeptidyl peptidase-4 inhibitor) were randomized to either 100 or 200 mg canagliflozin while continuing prior therapy. Patients were treated for 52 weeks in an open-label manner. Results Canagliflozin significantly reduced hemoglobin A1c, fasting plasma glucose and bodyweight in all the study groups. Improvements were apparent by 4 weeks of treatment, and were maintained for 52 weeks. The reduction in hemoglobin A1c ranged from −0.80 to −1.06%, and from −0.93 to −1.26% in the 100 and 200 mg canagliflozin groups, respectively. Drug-related adverse events occurred in approximately one-third of patients, and included hypoglycemia/asymptomatic hypoglycemia and pollakiuria. Hypoglycemia/asymptomatic hypoglycemia was most common in patients treated with a sulfonylurea. Most adverse events were classified as mild or moderate in severity. Conclusions The results of the present study confirmed that treatment with canagliflozin resulted in significant reductions in glycemic control and bodyweight that were maintained for 52 weeks of treatment irrespective of whether it was administered as monotherapy or in combination with another oral antihyperglycemic drug. Canagliflozin was well tolerated, with a low incidence of drug-related adverse events. This trial was registered with ClinicalTrials.gov (no. NCT01387737). PMID:25802729

    How to generalize from randomized placebo controlled trials of ADHD drug treatment in adults to 'real-world' clinical practice is intriguing. This open-labeled prospective observational study examined the effectiveness of long-term stimulant and non-stimulant medication in adult ADHD including dose, side-effects and comorbidity in a clinical setting. A specialized ADHD outpatient clinic gave previously non-medicated adults (n=250) with ADHD methylphenidate as first-line drug according to current guidelines. Patients who were non-tolerant or experiencing low efficacy were switched to amphetamine or atomoxetine. Primary outcomes were changes of ADHD-symptoms evaluated with the Adult ADHD Self-Report Scale (ASRS) and overall severity by the Global Assessment of Functioning (GAF). Secondary outcomes were measures of mental distress, and response on the Clinical-Global-Impressions-Improvement Scale. Data at baseline and follow-ups were compared in longitudinal mixed model analyses for time on-medication, dosage, comorbidity, and side-effects. As results, 232 patients (93%) completed examination at the 12 month endpoint, and 163 (70%) remained on medication. Compared with the patients who discontinued medication, those still on medication had greater percentage reduction in ASRS-scores (median 39%, versus 13%, P<0.001) and greater improvement of GAF (median 20% versus 4%, P<0.001) and secondary outcomes. Continued medication and higher cumulated doses showed significant associations to sustained improvement. Conversely, psychiatric comorbidity and side-effects were related to lower effectiveness and more frequent termination of medication. Taken together, one-year treatment with stimulants or atomoxetine was associated with a clinically significant reduction in ADHD symptoms and mental distress, and improvement of measured function. No serious adverse events were observed.

    Introduction Residual pain is a major factor in patient dissatisfaction following total hip arthroplasty or total knee arthroplasty (THA/TKA). The proportion of patients with unfavourable long-term residual pain is high, ranging from 7% to 34%. There are studies indicating that a preoperative degree of central sensitisation (CS) is associated with poorer postoperative outcomes and residual pain. It is thus hypothesised that preoperative treatment of CS could enhance postoperative outcomes. Duloxetine has been shown to be effective for several chronic pain syndromes, including knee osteoarthritis (OA), in which CS is most likely one of the underlying pain mechanisms. This study aims to evaluate the postoperative effects of preoperative screening and targeted duloxetine treatment of CS on residual pain compared with care-as-usual. Methods and analysis This multicentre, pragmatic, prospective, open-label, randomised controlled trial includes patients with idiopathic hip/knee OA who are on a waiting list for primary THA/TKA. Patients at risk for CS will be randomly allocated to the preoperative duloxetine treatment programme group or the care-as-usual control group. The primary end point is the degree of postoperative pain 6 months after THA/TKA. Secondary end points at multiple time points up to 12 months postoperatively are: pain, neuropathic pain-like symptoms, (pain) sensitisation, pain catastrophising, joint-associated problems, physical activity, health-related quality of life, depressive and anxiety symptoms, and perceived improvement. Data will be analysed on an intention-to-treat basis. Ethics and dissemination The study is approved by the local Medical Ethics Committee (METc 2014/087) and will be conducted according to the principles of the Declaration of Helsinki (64th, 2013) and the Good Clinical Practice standard (GCP), and in compliance with the Medical Research Involving Human Subjects Act (WMO).

    Small-molecule inhibitors of kinases involved in B-cell receptor signaling are an important advance in managing lymphoid malignancies. Entospletinib (GS-9973) is an oral, selective inhibitor of spleen tyrosine kinase. This multicenter, phase 2 study enrolled subjects with relapsed or refractory chronic lymphocytic leukemia (CLL; n = 41) or non-Hodgkin lymphoma (n = 145). Participants received 800 mg entospletinib twice daily. We report efficacy outcomes in the CLL cohort (n = 41) and safety outcomes in all cohorts (N = 186). The primary end point was a progression-free survival (PFS) rate at 24 weeks in subjects with CLL. The PFS rate at 24 weeks was 70.1% (95% confidence interval [CI], 51.3%-82.7%); median PFS was 13.8 months (95% CI, 7.7 months to not reached). The objective response rate was 61.0% (95% CI, 44.5%-75.8%), including 3 subjects (7.3%) who achieved nodal response with persistent lymphocytosis. Fifty-four subjects (29.0%) had serious adverse events (SAEs). The most common treatment-emergent SAEs included dyspnea, pneumonia, febrile neutropenia, dehydration, and pyrexia. Common grade 3/4 laboratory abnormalities included neutropenia (14.5%) and reversible alanine aminotransferase/aspartate aminotransferase elevations (13.4%). Entospletinib demonstrates clinical activity in subjects with relapsed or refractory CLL with acceptable toxicity. This trial was registered at www.clinicaltrials.gov as #NCT01799889.

    Once-daily deferasirox dispersible tablets (DT) have a well-defined safety and efficacy profile and, compared with parenteral deferoxamine, provide greater patient adherence, satisfaction, and quality of life. However, barriers still exist to optimal adherence, including gastrointestinal tolerability and palatability, leading to development of a new film-coated tablet (FCT) formulation that can be swallowed with a light meal, without the need to disperse into a suspension prior to consumption. The randomized, open-label, phase II ECLIPSE study evaluated the safety of deferasirox DT and FCT formulations over 24 weeks in chelation-naïve or pre-treated patients aged ≥10 years, with transfusion-dependent thalassemia or IPSS-R very-low-, low-, or intermediate-risk myelodysplastic syndromes. One hundred seventy-three patients were randomized 1:1 to DT (n = 86) or FCT (n = 87). Adverse events (overall), consistent with the known deferasirox safety profile, were reported in similar proportions of patients for each formulation (DT 89.5%; FCT 89.7%), with a lower frequency of severe events observed in patients receiving FCT (19.5% vs. 25.6% DT). Laboratory parameters (serum creatinine, creatinine clearance, alanine aminotransferase, aspartate aminotransferase and urine protein/creatinine ratio) generally remained stable throughout the study. Patient-reported outcomes showed greater adherence and satisfaction, better palatability and fewer concerns with FCT than DT. Treatment compliance by pill count was higher with FCT (92.9%) than with DT (85.3%). This analysis suggests deferasirox FCT offers an improved formulation with enhanced patient satisfaction, which may improve adherence, thereby reducing frequency and severity of iron overload-related complications.

    Background The current phase 1, open-label, dose escalation study was conducted to establish the safety, tolerability, pharmacokinetic profile, and preliminary antitumor activity of the novel mitochondrial inhibitor ME-344 in patients with refractory solid tumors. Methods Patients with refractory solid tumors were treated in a 3 + 3 dose escalation design. ME-344 was administered via intravenous infusion on days 1, 8, and 15 of the first 28-day cycle and weekly thereafter. Pharmacokinetics was assessed on days 1 and 15 of the first cycle. Results A total of 30 patients (median age, 65 years; 67% of whom were female) received ME-344. There were 5 dose-limiting toxicities reported. Four patients developed grade 3 neuropathy (2 patients each at doses of 15 mg/kg and 20 mg/kg) and 1 patient treated at a dose of 10 mg/kg developed a grade 3 acute myocardial infarction (toxicity was graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events [version 4.03]). The maximum tolerated dose (MTD) was defined as 10 mg/kg weekly. The most common adverse events were nausea, dizziness, and fatigue. At the MTD of 10 mg/kg, the maximal plasma concentration (Cmax) was 25.8 µg/mL and the area under the concentration curve from time zero to infinity was 25.9 hour*µg/mL. One patient with small cell lung cancer achieved a partial response for ≥52 weeks. Four patients had prolonged stable disease (1 patient each with urothelial carcinoma [47 weeks], carcinoid tumor [≥40 weeks], cervical leiomyosarcoma [39 weeks], and cervical cancer [≥31 weeks]). Conclusions The once-weekly administration of ME-344 was generally well tolerated in the current study, a first-in-human study; dose-limiting neuropathy was noted, but not at the MTD. Exposures at the 10-mg/kg dose level suggest a sufficient therapeutic index. The preliminary clinical activity as a monotherapy supports the further clinical development of ME-344 in combination with chemotherapy. The

    Little is known about the feasibility of switching patients with schizophrenia from long-acting injectable antipsychotics to oral olanzapine. We completed an open-label 14-week study to assess such a transition. This study included 25 stable outpatients (DSM-IV diagnosis of schizophrenia, schizophreniform disorder, or schizoaffective disorder) who were receiving long-acting injectable antipsychotics. Following a screening visit, patients began treatment with olanzapine 10 mg/day, which was initiated the day of their scheduled injection. Clinical assessments included the Clinical Global Impression-Improvement Scale (CGI-I) and the Positive and Negative Syndrome Scale (PANSS). Patient self-reports of adverse events were monitored and the Extrapyramidal Symptoms Rating Scale completed at each visit. In those completing the trial (N = 18), results revealed that a switch from injectable antipsychotics to olanzapine was associated with significant improvements on the CGI-I, negative symptoms, PANSS total scores, and parkinsonism. In considering the whole sample (last observation carried forward, N = 25), significant improvements on the CGI-I, parkinsonism, and dyskinesia were observed. Finally, those who failed to complete the trial (N = 7) did not change significantly from visit 1 to endpoint on any of the efficacy or safety measures. These results should be considered preliminary and require replication using appropriate control groups.

    Outcomes in early trials of bronchoscopic lung volume reduction using endobronchial valves for the treatment of patients with advanced emphysema were inconsistent. However improvements in patient selection with focus on excluding those with interlobar collateral ventilation and homogeneous emphysema resulted in significant benefits in the BeLieVeR-HIFi study compared with sham treated controls. In this manuscript we present data from the control patients in the BeLieVeR-HIFi study who went on to have open label endobronchial valve treatment after completion of the clinical trial (n=12), combined with data from those in the treatment arm who did not have collateral ventilation (n=19). Three months after treatment FEV1 increased by 27.3 (36.4)%, residual volume reduced by 0.49 (0.76) L, the 6 min walk distance increased by 32.6 (68.7) m and the St George Respiratory Questionnaire for COPD score improved by 8.2 (20.2) points. These data extend the evidence for endobronchial valve placement in appropriately selected patients with COPD. Trial registration number: ISRCTN04761234; Results. PMID:27999170

    Purpose To assess the effect of age and gender on the pharmacokinetics (PK) of the ghrelin receptor agonist anamorelin. Methods Three demographic cohorts of healthy subjects were enrolled in this single-center, open-label study. Subjects received a single oral dose (25 mg) of anamorelin HCl. Serial blood samples were collected over 24 hours to assess anamorelin PK and circulating growth hormone (GH) levels. Data were compared with a reference cohort. Results Anamorelin was rapidly absorbed in all cohorts; peak concentrations were observed 30–45 minutes and 2–4 hours post-dose, which declined biexponentially with mean terminal half-lives of 6–7 hours. An age effect on Cmax and AUC∞ was not apparent; however, mean AUC∞ values were approximately 1.8–1.9-fold higher in the female cohorts than in the reference male cohort. GH increase was rapid and virtually identical in both sexes, though attenuated in elderly subjects. No clinically significant safety or tolerability findings were observed. Conclusions While PK parameters do suggest higher exposure in females, this effect is considered to be modest given the variability of the 6–8 subjects per cohort. Moreover, no such effect was observed in the pharmacodynamic responses, thus, dose adjustment for age and gender is considered unnecessary. PMID:26640742

    Purpose: To evaluate the safety of velaglucerase alfa in patients with type 1 Gaucher disease who received velaglucerase alfa in the US treatment protocol HGT-GCB-058 (ClinicalTrials.gov identifier NCT00954460) during a global supply shortage of imiglucerase. Methods: This multicenter open-label treatment protocol enrolled patients who were either treatment naïve or had been receiving imiglucerase. Patients received intravenous velaglucerase alfa every other week at a dose of 60 U/kg (treatment naïve) or 15–60 U/kg (previously treated). Results: A total of 211 (including six treatment-naïve) patients were enrolled. Among the 205 previously treated patients, 35 (17.1%) experienced an adverse event considered related to study drug. Among the six treatment-naïve patients, one had an adverse event considered related to study drug. Infusion-related adverse events occurred in 28 (13.3%) of the 211 patients and usually occurred during the first three infusions. De novo, nonneutralizing, anti–velaglucerase alfa antibodies developed during treatment in one (<1.0%) previously treated patient and none of the treatment-naïve patients. Conclusion: The currently observed safety profile was consistent with those previously reported for imiglucerase and velaglucerase alfa phase III clinical trials. These results support the safety of initiating treatment with velaglucerase alfa or transitioning patients from imiglucerase therapy to velaglucerase alfa therapy. PMID:24263462

    This study was designed to explore the impact of Yoga and Meditation based lifestyle intervention (YMLI) on cellular aging in apparently healthy individuals. During this 12-week prospective, open-label, single arm exploratory study, 96 apparently healthy individuals were enrolled to receive YMLI. The primary endpoints were assessment of the change in levels of cardinal biomarkers of cellular aging in blood from baseline to week 12, which included DNA damage marker 8-hydroxy-2′-deoxyguanosine (8-OH2dG), oxidative stress markers reactive oxygen species (ROS), and total antioxidant capacity (TAC), and telomere attrition markers telomere length and telomerase activity. The secondary endpoints were assessment of metabotrophic blood biomarkers associated with cellular aging, which included cortisol, β-endorphin, IL-6, BDNF, and sirtuin-1. After 12 weeks of YMLI, there were significant improvements in both the cardinal biomarkers of cellular aging and the metabotrophic biomarkers influencing cellular aging compared to baseline values. The mean levels of 8-OH2dG, ROS, cortisol, and IL-6 were significantly lower and mean levels of TAC, telomerase activity, β-endorphin, BDNF, and sirtuin-1 were significantly increased (all values p < 0.05) post-YMLI. The mean level of telomere length was increased but the finding was not significant (p = 0.069). YMLI significantly reduced the rate of cellular aging in apparently healthy population. PMID:28191278

    Objectives. The current study aimed to compare the efficacy and safety of a classical anti-inflammatory beclomethasone nasal spray in comparison to a physic-chemical stabilizing ectoine containing nasal spray in the treatment of allergic rhinitis. Design and Methods. This was a noninterventional, open-label, observational trial investigating the effects of beclomethasone or ectoine nasal spray on nasal symptoms and quality of life. Over a period of 14 days, patients were asked to daily document their symptoms. Efficacy and tolerability were assessed by both physicians and patients. Results. Both treatments resulted in a significant decrease of TNSS values. An equivalence test could not confirm the noninferiority of ectoine treatment in comparison with beclomethasone treatment. Although clear symptom reduction was achieved with the ectoine products, the efficacy judgment showed possible advantages for the beclomethasone group. Importantly, tolerability results were comparably good in both groups, and a very low number of adverse events supported this observation. Both treatments resulted in a clear improvement in the quality of life as assessed by a questionnaire answered at the beginning and at the end of the trial. Conclusion. Taken together, it was shown that allergic rhinitis can be safely and successfully treated with beclomethasone and also efficacy and safety were shown for ectoine nasal spray.

    Cohesive polydensified matrix (CPM®) hyaluronic acid fillers are now available with or without lidocaine. The aim of this study was to investigate the safety and performance of CPM® fillers with lidocaine in the clinical setting. In an open-label, prospective, postmarketing study, 108 patients from seven sites in Germany and Denmark were treated with one or more lidocaine-containing CPM® fillers. Performance was assessed using the Merz Aesthetics Scales® (MAS). Pain was rated on an 11-point visual analog scale. Patients’ and physicians’ satisfaction as well as adverse events were recorded. Improvements of ≥1-point on MAS immediately after and 17 days posttreatment were observed in ~90% of patients compared with baseline. All investigators assessed ejection force, product positioning, and performance as similar or superior to the respective nonlidocaine products. Overall, 94% of investigators were satisfied with the esthetic outcomes and were willing to continue using the products. All patients except one were satisfied with the results, and all were willing to repeat the treatment. Mean pain scores were low during (<3.0) and after injection (<0.6). Except for one case of bruising, all adverse events were mild to moderate. CPM® fillers with lidocaine are safe and effective for a wide range of esthetic facial indications. PMID:27799807

    JAK2-V617F is central to the pathogenesis of myeloproliferative neoplasms. We examined whether lestaurtinib decreased JAK2-V617F allele burden and evaluated its clinical benefits and tolerability in patients with polycythaemia vera (PV) and essential thrombocythaemia (ET). This phase 2, open-label, multicentre study was designed to detect ≥15% reduction in JAK2-V617F allele burden in 15% of patients. Eligible patients received lestaurtinib 80 mg twice daily for 18 weeks and could participate in a 1-year extension phase of treatment. Of 39 enrolled patients, 27 (69%) had PV; 12 (31%) had ET. While the pre-specified responder rate of 15% was not met, lestaurtinib modestly reduced JAK2-V617F allele burden and reduced spleen size in a subset of patients. Of 37 patients in the full efficacy analysis, 5 (14%) responded clinically. Every patient had ≥1 adverse event, most commonly gastrointestinal (95%). Fifteen patients (38%) experienced serious adverse events; 23 (59%) withdrew due to adverse events. This is the first reported study of JAK2-inhibitor treatment in patients with PV/ET and highlights both the need for further studies to assess the role of JAK2 inhibition in treatment of PV/ET and the use of JAK2-V617F as a biomarker for response. This trial was registered at www.clinicaltrials.gov as NCT00586651.

    Introduction Status epilepticus (SE) is a life-threatening neurological emergency. SE lasting longer than 120 min and not responding to first-line and second-line antiepileptic drugs is defined as ‘refractory’ (RCSE) and requires intensive care unit treatment. There is currently neither evidence nor consensus to guide either the optimal choice of therapy or treatment goals for RCSE, which is generally treated with coma induction using conventional anaesthetics (high dose midazolam, thiopental and/or propofol). Increasing evidence indicates that ketamine (KE), a strong N-methyl-d-aspartate glutamate receptor antagonist, may be effective in treating RCSE. We hypothesised that intravenous KE is more efficacious and safer than conventional anaesthetics in treating RCSE. Methods and analysis A multicentre, randomised, controlled, open-label, non-profit, sequentially designed study will be conducted to assess the efficacy of KE compared with conventional anaesthetics in the treatment of RCSE in children. 10 Italian centres/hospitals are involved in enrolling 57 patients aged 1 month to 18 years with RCSE. Primary outcome is the resolution of SE up to 24 hours after withdrawal of therapy and is updated for each patient treated according to the sequential method.

    Action observation treatment has been proposed as therapeutic option in rehabilitation of patients affected by Parkinson's disease (PD) to improve freezing of gait episodes. The purpose of this prospective open-label feasibility study was to evaluate the impact of 8-week action observation training (video-therapy) for the treatment of postural instability and balance impairment in PD patients. Fifteen PD patients aged under 80 years with scores of 1 to 3 on the Hoehn and Yahr staging and without evidence of freezing of gait were recruited. They underwent 24 sessions of video-therapy training based on carefully watching video clips on motor tasks linked to balance, subsequently performing the same observed movements. No statistically significant differences were observed in the identified outcome measures with the Berg Balance Scale and the Activities-Specific Balance Confidence Scale after two months of follow-up. In the present study, a short course of action observation treatment seems to be not effective in reducing balance impairments and postural instability in patients affected by mild to moderate PD. Further studies with larger samples, longer follow-up period, and standardized protocols of action observation treatment are needed to investigate the effects of this rehabilitation technique in the management of postural and balance disorders of PD patients.

    We here report the results of a Phase I/IIa open-label four dose-escalation clinical study assessing the safety, tolerability, and possible therapeutic efficacy of a single intramuscular administration of DVC1-0101, a new gene transfer vector based on a nontransmissible recombinant Sendai virus (rSeV) expressing the human fibroblast growth factor-2 (FGF-2) gene (rSeV/dF-hFGF2), in patients with peripheral arterial disease (PAD). Gene transfer was done in 12 limbs of 12 patients with rest pain, and three of them had ischemic ulcer(s). No cardiovascular or other serious adverse events (SAEs) caused by gene transfer were detected in the patients over a 6-month follow-up. No infectious viral particles, as assessed by hemagglutination activity, were detected in any patient during the study. No representative elevation of proinflammatory cytokines or plasma FGF-2 was seen. Significant and continuous improvements in Rutherford category, absolute claudication distance (ACD), and rest pain were observed (P < 0.05 to 0.01). To the best of our knowledge, this is the first clinical trial of the use of a gene transfer vector based on rSeV. The single intramuscular administration of DVC1-0101 to PAD patients was safe and well tolerated, and resulted in significant improvements of limb function. Larger pivotal studies are warranted as a next step. PMID:23319060

    Background Pharmacogenetic-based dosing support tools have been developed to personalize antidepressant-prescribing practice. However, the clinical validity of these tools has not been adequately tested, particularly for specific antidepressants. Objective To examine the concordance between the actual dose and a polygene pharmacogenetic predicted dose of desvenlafaxine needed to achieve symptom remission. Materials and methods A 10-week, open-label, prospective trial of desvenlafaxine among Caucasian adults with major depressive disorder (n=119) was conducted. Dose was clinically adjusted and at the completion of the trial, the clinical dose needed to achieve remission was compared with the predicted dose needed to achieve remission. Results Among remitters (n=95), there was a strong concordance (Kendall’s τ-b=0.84, P=0.0001; Cohen’s κ=0.82, P=0.0001) between the actual and the predicted dose need to achieve symptom remission, showing high sensitivity (≥85%), specificity (≥86%), and accuracy (≥89%) of the tool. Conclusion Findings provide initial evidence for the clinical validity of a polygene pharmacogenetic-based tool for desvenlafaxine dosing. PMID:27779571

    2015-01-01

    Purpose To evaluate the efficacy, safety and patient satisfaction outcomes following low intensity extracorporeal shock wave therapy (LiESWT) in men with Peyronie's disease (PD) using a standardised protocol. Materials and Methods In this open-label single arm prospective study, patients with PD were enrolled following informed consent. Patient demographics, change in penile curvature and plaque hardness, International Index of Erectile Function (IIEF)-5 score, and overall satisfaction score (on a 5-point scale) were recorded. Treatment template consists of 3000 shock waves to the Peyronie's plaque over 20 minutes, twice weekly for 6 weeks. Results The majority of patients have PD history longer than 6 months (mean, 12.8 months; range, 6-28 months). Two thirds of patients have received and failed oral medical therapy. There were improvements in penile curvature (more than 15 degrees in 33% of men), plaque hardness (60% of men) and penile pain (4 out of 6 men) following LiESWT. There was a moderate improvement in IIEF-5 score (>5 points reported in 20% of men). No complication was reported and the majority of patients were satisfied (rated 4 out of 5; 70% of men) and would recommend this therapy to others. Conclusions In a carefully selected group of men with PD, LiESWT appears to be safe, has moderate efficacy and is associated with high patient satisfaction rate in the short term. PMID:26568796

    Objectives: Approximately one in two patients with multiple sclerosis (MS) suffer from comorbid depression. The primary objective of this study was to evaluate the safety and tolerability of fingolimod and antidepressant combination in relapsing–remitting MS patients with mild-to-moderate depression. Efficacy outcome variables were quality of life (QoL), fatigue, disability and depression. Methods: Patients received open-label fingolimod 0.5 mg over 2 weeks, followed by fingolimod plus citalopram (40 mg), fluoxetine (40 mg) or venlafaxine (150 mg) over 16 weeks. The antidepressant was selected at the physician’s discretion. Results: In total, 54 patients were recruited at 25 centres across Germany. No new safety signals (including cardiac) emerged compared with previous clinical studies. Adverse events (mostly mild-to-moderate) were reported in 43 patients. A total of three patients had serious adverse events and 10 discontinued the study. QoL (mean [95% confidence interval]) improved by 2.2 (−3.3, −1.2; Patient Reported Indices for MS questionnaire), fatigue by 8.2 (−13.1, −3.3; modified Fatigue Impact Scale) and depression by 6.3 (−8.4, −4.2; Hamilton Depression Scale) points. However, the results must be interpreted cautiously owing to limited patient numbers. Conclusions: Combination of fingolimod with antidepressant medication showed no unexpected safety signals. Patient-reported outcomes (QoL, disability, fatigue and depression) remained stable or improved. PMID:27582893

    This study was designed to explore the impact of Yoga and Meditation based lifestyle intervention (YMLI) on cellular aging in apparently healthy individuals. During this 12-week prospective, open-label, single arm exploratory study, 96 apparently healthy individuals were enrolled to receive YMLI. The primary endpoints were assessment of the change in levels of cardinal biomarkers of cellular aging in blood from baseline to week 12, which included DNA damage marker 8-hydroxy-2'-deoxyguanosine (8-OH2dG), oxidative stress markers reactive oxygen species (ROS), and total antioxidant capacity (TAC), and telomere attrition markers telomere length and telomerase activity. The secondary endpoints were assessment of metabotrophic blood biomarkers associated with cellular aging, which included cortisol, β-endorphin, IL-6, BDNF, and sirtuin-1. After 12 weeks of YMLI, there were significant improvements in both the cardinal biomarkers of cellular aging and the metabotrophic biomarkers influencing cellular aging compared to baseline values. The mean levels of 8-OH2dG, ROS, cortisol, and IL-6 were significantly lower and mean levels of TAC, telomerase activity, β-endorphin, BDNF, and sirtuin-1 were significantly increased (all values p < 0.05) post-YMLI. The mean level of telomere length was increased but the finding was not significant (p = 0.069). YMLI significantly reduced the rate of cellular aging in apparently healthy population.

    Objective The purpose of this study was to investigate the efficacy and tolerability of atypical antipsychotics (AAPs) with augmentation by blonanserin in schizophrenic patients. Methods aA total of 100 patients with schizophrenia who were partially or completely unresponsive to treatment with an AAP were recruited in this 12-week, open-label, non-comparative, multicenter study. Blonanserin was added to their existing AAP regimen, which was maintained during the study period. Efficacy was primarily evaluated using the Positive and Negative Syndrome Scale (PANSS) at baseline and at weeks 2, 4, 8, and 12. Predictors for PANSS response (≥20% reduction) were investigated. Results The PANSS total score was significantly decreased at 12 weeks of blonanserin augmentation (-21.0±18.1, F=105.849, p<0.001). Moreover, 51.0% of participants experienced a response at week 12. Premature discontinuation of blonanserin occurred in 17 patients (17.0%); 4 of these patients dropped out due to adverse events. The patients who benefited the most from blonanserin were those with severe symptoms despite a treatment with a higher dose of AAP. Conclusion Blonanserin augmentation could be an effective strategy for patients with schizophrenia who were partially or completely unresponsive to treatment with an AAP. PMID:27482249

    This open-label multicenter clinical trial conducted in Mexico assessed the immunogenicity and safety of a 13-valent pneumococcal conjugate vaccine (PCV13) in adults ≥50 years of age not previously vaccinated with the 23-valent pneumococcal polysaccharide vaccine (PPSV23). The PCV13 elicited a robust immune response in this study population, as reflected by the magnitude of fold rises in functional antibody levels measured by serotype-specific opsonophagocytic activity (OPA) assays before and 1 month after vaccination. Although the prevaccination OPA geometric mean titers (GMTs) for the majority of the serotypes were significantly lower in the 50- to 64-year age group than those in the ≥65-year age group, the postvaccination immune responses were generally similar. The overall immune responses were higher for the majority of the serotypes in the Mexican study population than those in similar adult study populations who received the PCV13 in Europe and the United States. PCV13 was well tolerated, and there were no vaccine-related serious adverse events. In conclusion, PCV13 is safe and immunogenic when administered to adults ≥50 years of age in Mexico and has the potential to protect against vaccine-type pneumococcal disease.

    The aim of this study was to investigate the effect of a rotigotine transdermal patch on stationary and non-stationary locomotion in de novo Parkinson disease (PD) patients in an open-label uncontrolled study. A 3-D gait analysis system was used to investigate four different locomotor tasks: steady-state linear walking, gait initiation, gait termination and 180°-turning. A series of gait variables were measured for each locomotor task. PD patients who received rotigotine treatment (4-8 mg) displayed: (1) increased step length, gait speed, cadence and arm oscillations, and reduced double support duration and step asymmetry during steady-state linear gait; (2) increased initial step length during gait initiation; (3) increased final step length and gait speed, and decreased stability index during gait termination; (4) decreased duration of turning and head-pelvis delays during 180°-turning. The main finding that emerges from the present study is that the dopamine agonist rotigotine can improve various aspects of gait in de novo PD patients.

    Introduction Mycophenolate sodium, an enteric-coated tablet (EC-MPS), is as effective and safe as mycophenolate mofetil (MMF) in preventing transplant rejection. EC-MPS and MMF improve the outcome of severe lupus nephritis (LN) and have fewer side effects than pulsed intravenous cyclophosphamide. Blood concentrations of mycophenolic acid (MPA), the active metabolite of EC-MPS, vary between participants despite fixed dosing. Interpatient variability has been studied in transplantation, but not well documented in LN. The relationship between MPA concentration and its clinical effect on LN has not been described. Methods and analysis This is a prospective, open-label, randomised controlled trial. –32 participants with LN who meet the inclusion and exclusion criteria will be randomised into two groups: one receiving a fixed dose of EC-MPS and the second, a dosing regimen that is titrated with therapeutic drug monitoring. Included participants will have blood sampled over a period of 8–12 h on three different occasions. Pharmacokinetic parameters will be calculated using non-compartmental methods. Ethics and dissemination The Human Research and Ethics Committee of the Royal Brisbane Women's Hospital have approved this study. The study is registered with Australian and New Zealand Clinical Trials Registry—ACTRN12611000798965 We planned to present the de-identified information at conferences and publish the results in medical journals.

    Long-term efficacy of internal globus pallidus (GPi) deep-brain stimulation (DBS) in DYT1 dystonia and disease progression under DBS was studied. Twenty-six patients of this open-label study were divided into two groups: (A) with single bilateral GPi lead, (B) with a second bilateral GPi lead implanted owning to subsequent worsening of symptomatology. Dystonia was assessed with the Burke Scale. Appearance of new symptoms and distribution according to body region were recorded. In the whole cohort, significant decreases in motor and disability subscores (P < 0.0001) were observed at 1 year and maintained up to 10 years. Group B showed worsening of the symptoms. At 1 year, there were no significant differences between Groups A (without subsequent worsening) and B; at 5 years, a significant difference was found for motor and disability scores. Within Group B, four patients exhibited additional improvement after the second DBS surgery. In the 26 patients, significant difference (P = 0.001) was found between the number of body regions affected by dystonia preoperatively and over the whole follow-up. DBS efficacy in DYT1 dystonia can be maintained up to 10 years (two patients). New symptoms appear with long-term follow-up and may improve with additional leads in a subgroup of patients.

    Objective We investigated the efficacy and tolerability of paliperidone extended-release (ER) tablets in patients with first-episode psychosis (n=75). Methods This was an 8-week, open-label, multicenter trial. The primary outcome variable was scores on the Positive and Negative Syndrome Scale (PANSS); secondary measures included the Scale for the Assessment of Negative Symptoms (SANS), the Cognitive Assessment Interview (CAI), and the Global Assessment of Functioning (GAF). To assess safety, we measured drug-related adverse events, weight, lipid-related variables, and prolactin and administered the Simpson–Angus Rating Scale (SARS), the Abnormal Involuntary Movement Scale (AIMS), the Barnes Akathisia Scale (BAS), the Arizona Sexual Experiences Scale (ASEX), and the Udvalg for Kliniske Undersogelser side effect rating scale (UKU). Results The administration of paliperidone ER resulted in significant improvement in the PANSS, SANS, CAI, and GAF scores (p<0.001) over time. This improvement was evident as early as 1 week. The most frequent adverse events were akathisia, somnolence, anxiety, and sedation, which were well tolerated. Modest increases in weight and lipid profiles were also noted. Prolactin levels were substantially increased at the endpoint in both male and female patients. Conclusion These results indicate that paliperidone ER is effective and is characterized by good tolerability in the treatment of positive and negative symptoms and cognitive functioning in first-episode psychosis.

    Long-term safety of once-daily ropinirole extended/prolonged release (ropinirole XL/PR) was evaluated in subjects with early and advanced Parkinson's disease (PD) in this study, 101468/248. Subjects (n = 419) who completed one of three prior studies evaluating ropinirole XL/PR for the treatment of PD were enrolled in this open-label, multicenter, extension study, and were to be followed for up to 73 months. Ropinirole XL/PR was titrated/continued, and adjusted as appropriate during the maintenance phase (maximum 24 mg/d). Levodopa (L-dopa) and other nondopamine agonist PD medications were permitted. Safety outcomes that were investigated included frequency of adverse events (AEs). Subjects' preference regarding once daily versus three times daily study medication regimens was also investigated in a subset of the study population. The median duration of ropinirole XL/PR exposure was 1275 d. Most subjects (87%) reported at least one AE, with the most common (≥ 10%) AEs being, back pain (14%), hallucinations (13%), somnolence (11%) and peripheral edema (11%). Twenty-five percent of subjects discontinued the study prematurely due to an AE during the treatment period. Long-term treatment with ropinirole XL/PR was not associated with any new or unexpected safety concerns in patients with early and advanced PD, and a majority of subjects preferred the once-daily dosing regimen.

    Objective: To evaluate the efficacy and tolerability of ranolazine as an add-on drug in chronic stable angina patients and the impact of ranolazine on the quality of life in chronic stable angina patients receiving other antianginal medications. Materials and Methods: It was a prospective, open-label, hospital-based study involving 144 patients with chronic stable angina. First group received either metoprolol 12.5 or 25 mg/day or other antianginal medications; if the symptoms persist, the dose of metoprolol was increased to 50 mg/day, and to the second group, ranolazine 500 mg BD or 1 g OD was added along with metoprolol or others if the anginal attacks were not subsiding. The patients were followed up to 6 months with electrocardiography, treadmill test, and quality of life questionnaire. Adverse events were recorded at each visit during the study. Results: There was a statistically significant reduction in weekly anginal frequency (P < 0.001) and improvement in an exercise tolerance in both the groups, but more in the ranolazine group. Adverse events reported were mild, infrequent. Conclusion: Ranolazine is could be used as an add-on drug in chronic angina patients not improved with metoprolol or antianginal medications.

    Serelaxin, a recombinant human relaxin-2 hormone, is in clinical development for treating acute heart failure. This open-label, parallel-group study investigated serelaxin pharmacokinetics (PK) after a single 4-hour intravenous infusion (10 µg/kg) in patients with severe renal impairment (n = 6) or end-stage renal disease (ESRD) requiring hemodialysis (PK on the day of dialysis [n = 6] or during dialysis-free interval [n = 6]), compared with matched healthy subjects (n = 18). In all participants, serum serelaxin concentration peaked at the end of infusion and subsequently declined with mean terminal elimination half-life of 6.5-8.8 hours. Compared with healthy subjects, a moderate decrease in serelaxin systemic clearance (37%-52%) and increase in its exposure (30%-115%) were observed in all patients. During the 4-hour hemodialysis in ESRD patients, 30% serelaxin was removed, with hemodialysis clearance constituting approximately 52% of total systemic clearance. Serelaxin was well tolerated with no deaths, serious adverse events (AE), or AE-related discontinuations. Antiserelaxin antibodies were not detected in any participant. Given the shallow dose-response relationship observed with serelaxin in clinical studies and its wide therapeutic window, the observed PK differences in patients with severe renal impairment compared with healthy subjects are unlikely to pose a safety risk and do not warrant a predefined dosage adjustment in such patients.

    Objectives. The current study aimed to compare the efficacy and safety of a classical anti-inflammatory beclomethasone nasal spray in comparison to a physic-chemical stabilizing ectoine containing nasal spray in the treatment of allergic rhinitis. Design and Methods. This was a noninterventional, open-label, observational trial investigating the effects of beclomethasone or ectoine nasal spray on nasal symptoms and quality of life. Over a period of 14 days, patients were asked to daily document their symptoms. Efficacy and tolerability were assessed by both physicians and patients. Results. Both treatments resulted in a significant decrease of TNSS values. An equivalence test could not confirm the noninferiority of ectoine treatment in comparison with beclomethasone treatment. Although clear symptom reduction was achieved with the ectoine products, the efficacy judgment showed possible advantages for the beclomethasone group. Importantly, tolerability results were comparably good in both groups, and a very low number of adverse events supported this observation. Both treatments resulted in a clear improvement in the quality of life as assessed by a questionnaire answered at the beginning and at the end of the trial. Conclusion. Taken together, it was shown that allergic rhinitis can be safely and successfully treated with beclomethasone and also efficacy and safety were shown for ectoine nasal spray. PMID:24976831

    Hirstiella spp. are common ectoparasites of captive green iguanas (Iguana iguana). Suggested treatments are empirical and some of them are of low efficacy and potentially toxic. The objective of this open-label study was to investigate the short-term efficacy and safety of a single application of 0·25% fipronil solution for the treatment of hirstiellosis. The skin of 50 green iguanas was thoroughly examined with the aid of bright light and magnifying lenses. A total of 21 iguanas were found to be infested, harbouring 1-24 mites (median: 5). All 35 mites collected from 17 iguanas were identified as Hirstiella sp. Both infested and non-infested lizards, sharing the same enclosure, were carefully wiped with 0·25% fipronil solution. The safety and the efficacy of the treatment were evaluated after 2 days in 47/50 (94%) and 7 days in 29/50 (58%) iguanas. Compared with pre-treatment levels, the parasitic load did not changed significantly on the second day but was significantly lower on day 7 (P = 0·006). No adverse reactions were noticed. Based on these results a single whole-body application of 0·25% fipronil solution can be considered a safe and effective treatment for the reduction of parasitic burden in captive green iguanas infested by Hirstiella sp. mites.

    Cancer pain is a prevalent and serious public health issue, and more effective treatments are needed. This study evaluates the analgesic activity of tetrodotoxin, a highly selective sodium channel blocker, in cancer pain. A Phase IIa, open-label, multicenter, dose-escalation study of intramuscular tetrodotoxin was conducted in patients with severe, unrelieved cancer pain. The study design called for six ascending dose levels of intramuscular tetrodotoxin, administered over a four-day treatment period in hospitalized patients, with six patients to be enrolled within each successive dose level. Twenty-four patients underwent 31 courses of treatment at doses ranging from 15 to 90 microg daily, administered in divided doses, over four days. Most patients described transient perioral tingling or other mild sensory phenomena within about an hour of each treatment. Nausea and other toxicities were generally mild, but two patients experienced a serious adverse event, truncal and gait ataxia, that resolved over days. Seventeen of 31 treatments resulted in clinically meaningful reductions in pain intensity, and relief of pain persisted for up to two weeks or longer. Two patients had opioids held due to narcosis concurrent with relief of pain. Somatic, visceral, or neuropathic pain could all respond, but it was not possible to predict which patients were more likely to have an analgesic effect. Tetrodotoxin was overall safe. It effectively relieved severe, treatment-resistant cancer pain in the majority of patients and often for prolonged periods after treatment. It may have a novel mechanism of analgesic effect. Further study is warranted.

    Background We report here data from the >200 patients recruited in Russia to take part in OSVaLD, a 12-week, open-label, post-marketing surveillance study of the response to betahistine 48 mg/day in vertigo of peripheral vestibular origin carried out in a total of 13 countries. Methods The primary efficacy endpoint was change in the Dizziness Handicap Inventory (DHI; 100-point scale). Changes in Hospital Anxiety and Depression Scale (HADS) and Medical Outcomes Study Short-Form 36, version 2 (SF-36v2®) scores were a priori secondary Outcomes. Results Total DHI score improved by 43 points during betahistine treatment. This aggregate improvement was equally distributed across the three domains of the DHI (physical, emotional, and functional; P<0.0001 for main and subscore changes from baseline). Statistically significant improvements versus baseline were also observed in mean HADS scores for anxiety and depression (both P<0.0001), and in the Physical Component Summary and Mental Component Summary scores of the SF-36v2 (both P<0.0001 versus baseline). Only one suspected adverse drug reaction was recorded in the Russian safety population (n=204), indicating that betahistine was well tolerated in those patients. Conclusion Betahistine 48 mg/day was associated with clear improvements in well-configured and widely validated measures of health-related quality of life and an encouraging tolerability profile in patients in Russia who took part in OSVaLD.

    Summary Background In metastatic renal cell carcinoma combinations of interferon alfa-2a, interleukin-2, and fluorouracil produce higher response rates and longer progression-free survival than do single agents. We aimed to compare overall survival in patients receiving combination treatment or interferon alfa-2a. Methods RE04/30012 was an open-label randomised trial undertaken in 50 centres across eight countries. 1006 treatment-naive patients diagnosed with advanced metastatic renal cell carcinoma were randomly allocated (1 to 1) by minimisation to receive interferon alfa-2a alone or combination therapy with interferon alfa-2a, interleukin-2, and fluorouracil. Treatment was not masked. The primary endpoint was overall survival. Treatment groups were compared with a non-stratified log-rank test. Analysis was by intention to treat. This study is registered, number ISRCTN 46518965. Findings 502 patients were randomly assigned to receive interferon alfa-2a and 504 to receive combined treatment. Median follow-up was 37·2 months (24·8–52·3). Median overall survival was 18·8 months (17·0–23·2) for patients receiving interferon alfa-2a versus 18·6 months (16·5–20·6) for those receiving combination therapy. Overall survival did not differ between the two groups (hazard ratio 1·05 [95% CI 0·90–1·21], p=0·55; absolute difference 0·3% (−5·1 to 5·6) at 1 year and 2·7% (−8·2 to 2·9) at 3 years). Serious adverse events were reported in 113 (23%) patients receiving interferon alfa-2a and 131 (26%) of those receiving combined treatment. Interpretation Although combination therapy does not improve overall or progression-free survival compared with interferon alfa-2a alone, immunotherapy might still have a role because it can produce remissions that are of clinically relevant length in some patients. Identification of patients who will benefit from immunotherapy is crucial. Funding UK Medical Research Council. PMID:20153039

    Background Malaria remains one of the most important causes of morbidity and mortality in pregnant women and their newborn babies in sub-Saharan Africa. Intermittent preventive treatment in pregnancy (IPTp) is recommended by the World Health Organization (WHO) to reduce the burden of disease and improve maternal and neonatal survival and general health. Due to the growing resistance to sulfadoxine-pyrimethamine (SP), the current WHO-recommended drug for IPTp, identification of new and effective drugs is an urgent priority. Methods and Findings This was an open-label, non-comparative study (NCT01103713) in 5 countries in East and sub-Saharan Africa (Benin, Kenya, Malawi, Tanzania, and Uganda) to assess parasitological response and drug concentrations of a single, 3-day course of four tablets of a fixed-dose combination of azithromycin-chloroquine (AZCQ) 250/155 mg given during the second or third trimester to women with asymptomatic Plasmodium falciparum parasitemia in their first or second pregnancy. Parasitemia was determined by microscopy and molecular genotyping was performed to characterize parasites relative to the baseline infection. Weekly follow-up visits took place until day 42 after first dose and additional follow-up occurred after delivery. Systemic concentrations of azithromycin (AZ), chloroquine (CQ), and the CQ metabolite, desethyl CQ (DECQ) were evaluated at Day 0 (pre-dose), at Day 2 (pre-dose, 2 and 8 hours) and randomly at Days 7 and 14. Systemic concentrations of CQ and DECQ were also measured randomly at Day 21 and Day 28. In total, 404 women were screened for eligibility and 168 were treated, 155 of whom completed the study. PCR-adjusted parasitological response in the modified intent-to-treat population at day 28 (the primary efficacy endpoint) was estimated by the Kaplan-Meier method as 99.35% (95% confidence interval [CI]: 97.76, 100.00). PCR-adjusted parasitological response remained high at day 42 (95.19%; 95% CI: 91.35, 99.03). In

    Background This pilot study investigated changes in remyelinating and demyelinating activity in normal appearing brain tissue (NABT) and lesions, by using voxel-wise magnetization transfer ratio (VW-MTR), in patients with relapsing–remitting multiple sclerosis (RRMS) receiving interferon beta-1a 44 mcg subcutaneously (IFN β-1a SC) three times weekly versus healthy controls (HCs) (NCT01085318). Methods Increasing (suggestive of remyelination) and decreasing (suggestive of demyelination) VW-MTR changes in NABT and in T2, T1 and gadolinium (Gd)-enhancing lesion volume were measured over 24 weeks in 23 patients treated with IFN β-1a SC and in 15 HCs (where applicable). VW-MTR changes were tested using the Wilcoxon signed–rank or Wilcoxon rank–sum test. Results A trend for greater volume of NABT with increasing VW-MTR at 24 weeks was observed for patients versus HCs (median [range] 1206 [0–15278]; 342 [0–951] mm3; p = 0.061). NABT volume with increasing VW-MTR at 12 weeks was significantly greater in patients than in HCs (852 [6–11577]; 360 [0–1755] mm3; p = 0.028). Similar findings were detected for lesion volumes. Two patients with notably high numbers of Gd-enhancing lesions at baseline had a markedly greater volume of tissue with increasing VW-MTR compared with other patients. Volume of NABT tissue with decreasing VW-MTR was significantly greater in patients versus HCs at 24 weeks (942 [0–6141]; 297 [0–852] mm3; p<0.001). Conclusions The significant change in NABT volume with increasing VW-MTR at 12 weeks suggests that active remyelination in patients with RRMS may occur during treatment with IFN β-1a SC. Findings from two patients with the highest number of Gd-enhancing lesions at baseline suggest that extensive remyelination in NABT may occur in patients with high disease activity. Tissue volume with decreasing VW-MTR was greater in patients than in HCs, despite treatment, validating the sensitivity of this technique for detecting MS

  8. Efficacy and safety of fluticasone furoate 100 μg and 200 μg once daily in the treatment of moderate-severe asthma in adults and adolescents: a 24-week randomised study

    2014-01-01

    Background Inhaled corticosteroids are a mainstay of therapy for persistent asthma, but suboptimal adherence with twice-daily use is widespread. Fluticasone furoate (FF) is a new inhaled corticosteroid (ICS) suitable for once-daily dosing in asthma. This study was performed to descriptively assess the efficacy and safety of two doses of FF, with no planned formal statistical hypothesis testing. Methods This was a 24-week double-blind, multicentre, parallel-group study (NCT01431950). Patients aged ≥ 12 years with moderate-severe persistent asthma and uncontrolled on mid-high dose ICS were stratified by baseline FEV1 and randomised (1:1) to treatment with FF 100 μg or 200 μg once daily in the evening. The primary endpoint was change from baseline trough FEV1 after 24 weeks; secondary and other endpoints included peak expiratory flow (PEF) and rescue-free and symptom-free 24-hour periods over Weeks 1–24, and Asthma Control Test™ (ACT) score at Week 24. A pre-specified subgroup analysis of patients by randomisation strata was performed for the primary and selected secondary and other endpoints. Safety assessments included adverse events, laboratory and vital sign measurements, and change from baseline in 24-hour urinary cortisol at Week 24. Results With FF 100 μg and 200 μg, least squares mean trough FEV1 improved from baseline by 208 mL and 284 mL, respectively, at Week 24; treatment difference: 77 mL (95% CI: –39, 192). Similar improvements from baseline in rescue- and symptom-free periods, and morning and evening PEF were observed in both groups. Patients were 42% more likely to be well-controlled (ACT score ≥ 20) with FF 200 μg than with FF 100 μg. Slightly more patients receiving FF 200 μg vs. FF 100 μg reported adverse events (63% vs. 59%) and events deemed treatment related (5% vs. <1%). Seven serious adverse events (FF 200 μg 4; FF 100 μg 3) were reported, none of which were deemed treatment related. No clinically relevant effects of either

    Background.  Many human immunodeficiency virus (HIV)-infected patients remain on nevirapine-based antiretroviral therapy (ART) despite safety and efficacy concerns. Switching to a rilpivirine-based regimen is an alternative, but there is little experience with rilpivirine in sub-Saharan Africa where induction of rilpivirine metabolism by nevirapine, HIV subtype, and dietary differences could potentially impact efficacy. Methods.  We conducted an open-label noninferiority study of virologically suppressed (HIV-1 ribonucleic acid [RNA] < 50 copies/mL) HIV-1-infected Rwandan adults taking nevirapine plus 2 nucleos(t)ide reverse-transcriptase inhibitors. One hundred fifty participants were randomized 2:1 to switch to coformulated rilpivirine-emtricitabine-tenofovir disoproxil fumarate (referenced as the Switch Arm) or continue current therapy. The primary efficacy endpoint was HIV-1 RNA < 200 copies/mL at week 24 assessed by the US Food and Drug Administration Snapshot algorithm with a noninferiority margin of 12%. Results.  Between April and September 2014, 184 patients were screened, and 150 patients were enrolled; 99 patients switched to rilpivirine-emtricitabine-tenofovir, and 51 patients continued their nevirapine-based ART. The mean age was 42 years and 43% of participants were women. At week 24, virologic suppression (HIV-1 RNA level <200 copies/mL) was maintained in 93% and 92% in the Switch Arm versus the continuation arm, respectively. The Switch Arm was noninferior to continued nevirapine-based ART (efficacy difference 0.8%; 95% confidence interval, -7.5% to +12.0%). Both regimens were generally safe and well tolerated, although 2 deaths, neither attributed to study medications, occurred in participants in the Switch Arm. Conclusions.  A switch from nevirapine-based ART to rilpivirine-emtricitabine-tenofovir disoproxil fumarate had similar virologic efficacy to continued nevirapine-based ART after 24 weeks with few adverse events.

    Background. Direct-acting antiviral agents against HCV with or without peginterferon plus ribavirin result in higher eradication rates of HCV and shorter treatment duration. We examined which is better for predicting persistent virologic response, the assessment of serum HCV RNA at 12 or 24 weeks after the end of treatment for predicting sustained virologic response (SVR12 or SVR24, respectively) in patients treated by HCV NS3/4A protease inhibitors with peginterferon plus ribavirin. Methods. In all, 149 Japanese patients infected with HCV genotype 1b treated by peginterferon plus ribavirin with telaprevir or simeprevir were retrospectively analyzed: 59 and 90 patients were treated with telaprevir- and simeprevir-including regimens, respectively. HCV RNA was measured by TaqMan HCV Test, version 2.0, real-time PCR assay. SVR12 or SVR24, respectively, was defined as HCV RNA negativity at 12 or 24 weeks after ending treatment. Results. Total SVR rates were 78.0% and 66.7% in the telaprevir and simeprevir groups, respectively. In the telaprevir group, all 46 patients with SVR12 finally achieved SVR24. In the simeprevir group, 60 (93.8%) of the total 64 patients with SVR12 achieved SVR24, with the other 4 patients all being previous-treatment relapsers. Conclusions. SVR12 was suitable for predicting persistent virologic response in almost all cases. In simeprevir-including regimens, SVR12 could not always predict persistent virologic response. Clinicians should use SVR24 for predicting treatment outcome in the use of HCV NS3/4A protease inhibitors with peginterferon plus ribavirin for any group of real-world patients chronically infected with HCV.

    Female SNF(1) hybrid mice spontaneously develop an immune complex-mediated glomerulonephritis as early as 24 weeks of age, whereas the disease onset in males is much slower. Further, a rise in concentration of glomerulus-specific autoantibodies via autoreactive B cells is critical to progression of the disease in this strain. Environmental factors contributing to the onset or degree of such autoimmunity are of interest yet poorly understood. In the present study, time-pregnant SWR x NZB dams (10/treatment) were gavaged on gestational 12 with 40 or 80 mg/kg 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), and the SNF(1) offspring were evaluated at 24 weeks of age. Bone marrow B220(low)CD24(-)AA4.1(+) committed B lineage progenitors were increased in female offspring by TCDD, however, committed progenitors and pro-B cells were decreased in males. Splenic marginal zone B cells (CD21(hi)CD24(low-int)) were decreased and follicular B cells (CD21(int)CD24(low)) were increased across sex by prenatal TCDD, whereas transitional-2 B cells (CD21(int)CD24(hi)) and (CD23(low-int) CD1(low-int)) were decreased in males only. Antibodies to double-stranded DNA were significantly increased across sex by TCDD. Anti-IgG and anti-C3 immune complex renal deposition was visibly worsened in females, and present in TCDD-treated males. These data suggest that developmental exposure to TCDD permanently and differentially alters humoral immune function by sex, and exacerbates a type III hypersensitivity lupus-like autoimmune disease in genetically predisposed mice.

    Combined Janus kinase 1 (JAK1) and JAK2 inhibition therapy effectively reduces splenomegaly and symptom burden related to myelofibrosis but is associated with dose-dependent anemia and thrombocytopenia. In this open-label phase II study, we evaluated the efficacy and safety of three dose levels of INCB039110, a potent and selective oral JAK1 inhibitor, in patients with intermediate- or high-risk myelofibrosis and a platelet count ≥50×109/L. Of 10, 45, and 32 patients enrolled in the 100 mg twice-daily, 200 mg twice-daily, and 600 mg once-daily cohorts, respectively, 50.0%, 64.4%, and 68.8% completed week 24. A ≥50% reduction in total symptom score was achieved by 35.7% and 28.6% of patients in the 200 mg twice-daily cohort and 32.3% and 35.5% in the 600 mg once-daily cohort at week 12 (primary end point) and 24, respectively. By contrast, two patients (20%) in the 100 mg twice-daily cohort had ≥50% total symptom score reduction at weeks 12 and 24. For the 200 mg twice-daily and 600 mg once-daily cohorts, the median spleen volume reductions at week 12 were 14.2% and 17.4%, respectively. Furthermore, 21/39 (53.8%) patients who required red blood cell transfusions during the 12 weeks preceding treatment initiation achieved a ≥50% reduction in the number of red blood cell units transfused during study weeks 1–24. Only one patient discontinued for grade 3 thrombocytopenia. Non-hematologic adverse events were largely grade 1 or 2; the most common was fatigue. Treatment with INCB039110 resulted in clinically meaningful symptom relief, modest spleen volume reduction, and limited myelosuppression. PMID:27789678

    Introduction Diabetes mellitus and diabetic nephropathy (DN) are prevalent and costly to manage. DN is the leading cause of end-stage kidney disease. Conventional therapy blocking the renin–angiotensin system has only achieved limited effect in preserving renal function. Recent observational data show that the use of Chinese medicine (CM), a major form of traditional medicine used extensively in Asia, could reduce the risk of end-stage kidney disease. However, existing clinical practice guidelines are weakly evidence-based and the effect of CM remains unclear. This trial explores the effect of an existing integrative Chinese–Western medicine protocol for the management of DN. Objective To optimise parameters and assess the feasibility for a subsequent phase III randomised controlled trial through preliminary evaluation on the effect of an adjuvant semi-individualised CM treatment protocol on patients with type 2 diabetes with stages 2–3 chronic kidney disease and macroalbuminuria. Methods and analysis This is an assessor-blind, add-on, randomised, controlled, parallel, multicentre, open-label pilot pragmatic clinical trial. 148 patients diagnosed with DN will be recruited and randomised 1:1 to a 48-week additional semi-individualised CM treatment programme or standard medical care. Primary end points are the changes in estimated glomerular filtration rate and spot urine albumin-to-creatinine ratio between baseline and treatment end point. Secondary end points include fasting blood glucose, glycated haemoglobin, brain natriuretic peptide, fasting insulin, C peptide, fibroblast growth factor 23, urinary monocyte chemotactic protein-1, cystatin C, nephrin, transforming growth factor-β1 and vascular endothelial growth factor. Adverse events are monitored through self-completed questionnaire and clinical visits. Outcomes will be analysed by regression models. Enrolment started in July 2015.

  15. Evaluation of miglustat as maintenance therapy after enzyme therapy in adults with stable type 1 Gaucher disease: a prospective, open-label non-inferiority study

    PubMed Central

    2012-01-01

    Background Previous studies have provided equivocal data on the use of miglustat as maintenance therapy in Gaucher disease type 1. We report findings from a clinical trial evaluating the effects of miglustat treatment in patients with stable type 1 Gaucher disease after enzyme therapy. Methods Adult type 1 Gaucher disease patients stabilized during at least 3 years of previous enzyme therapy were included in this 2-year, prospective, open-label non-inferiority study. The primary endpoint was percent change from baseline in liver volume. Secondary endpoints included changes in spleen volume, hemoglobin concentration and platelet count. Results Forty-two patients were enrolled (mean±SD age, 45.1±12.7 years; previous enzyme therapy duration 9.5±4.0 years). Median (range) exposure to miglustat 100 mg t.i.d. was 658 (3–765) days. Twenty-one patients discontinued treatment prematurely; 13 due to adverse events, principally gastrointestinal. The upper 95% confidence limit of mean percent change in liver volume from baseline to end of treatment was below the non-inferiority margin of 10% (–1.1%; 95%CI −6.0, 3.9%). Mean (95%CI) changes in spleen volume, hemoglobin concentration and platelet count were 102 (24,180) mL, –0.95 (−1.38, –0.53) g/dL and −44.1 (–57.6, –30.7) ×109/L, respectively. Conclusions The primary efficacy endpoint was met; overall there was no change in liver volume during 24 months of miglustat therapy. Several patients showed a gradual deterioration in some disease manifestations, suggesting that miglustat could maintain clinical stability, but not in all patients. Miglustat demonstrated a predictable profile of safety and tolerability that was consistent with that reported in previous clinical trials and experience in clinical practice.

    Background and Objectives Natalizumab reduces the relapse rate and magnetic resonance imaging activity in patients with Relapsing-Remitting Multiple Sclerosis (RRMS). So far the influence of natalizumab on cognitive functions and fatigue in MS remains uncertain. The aim of this prospective, open-label, observational study was to evaluate the possible effects of natalizumab on cognition and fatigue measures in RRMS patients treated for up to two years. Methods Cognitive performances were examined by the Rao's Brief Repeatable Battery (BRB), the Stroop test (ST) and the Cognitive Impairment Index (CII), every 12 months. Patients who failed in at least 3 tests of the BRB and the ST were classified as cognitively impaired (CI). Fatigue Severity Scale (FSS) was administered every 12 months to assess patient's self-reported fatigue. One hundred and 53 patients completed 1 and 2 year-natalizumab treatment, respectively. Results After 1 year of treatment the percentage of CI patients decreased from 29% (29/100) at baseline to 19% (19/100) (p = 0.031) and the mean baseline values of CII (13.52±6.85) and FSS (4.01±1.63) scores were significantly reduced (10.48±7.12, p<0.0001 and 3.61±1.56, p = 0.008). These significant effects were confirmed in the subgroup of patients treated up to two years. Conclusions These results demonstrate that a short-term NTZ treatment may significantly improve cognitive performances and fatigue in RRMS patients. PMID:22558238

    This prospective 12-week open-label trial evaluates the tolerability and efficacy of memantine hydrochloride for the treatment of core social and cognitive deficits in adults with high-functioning autism spectrum disorder (ASD). Measures for assessment of therapeutic response included the Social Responsiveness Scale-Adult Research Version (SRS-A), disorder-specific Clinical Global Impression scales, Behavior Rating Inventory of Executive Functioning-Adult Self-Report, Diagnostic Analysis of Nonverbal Accuracy Scale, and Cambridge Neuropsychological Test Automated Battery. Eighteen adults (mean age, 28 ± 9.5 years) with high-functioning ASD (SRS-A raw score, 99 ± 17) were treated with memantine (mean dose, 19.7 ± 1.2 mg/d; range, 15-20 mg), and 17 (94%) completed the trial. Treatment with memantine was associated with significant reduction on informant-rated (SRS-A, -28 ± 25; P < 0.001) and clinician-rated (Clinical Global Impression-Improvement subscale ≤2, 83%) measures of autism severity. In addition, memantine treatment was associated with significant improvement in ADHD and anxiety symptom severity. Significant improvement was noted in nonverbal communication on the Diagnostic Analysis of Nonverbal Accuracy Scale test and in executive function per self-report (Behavior Rating Inventory of Executive Functioning-Adult Self-Report Global Executive Composite, -6 ± 8.8; P < 0.015) and neuropsychological assessments (Cambridge Neuropsychological Test Automated Battery). Memantine treatment was generally well tolerated and was not associated with any serious adverse events. Treatment with memantine appears to be beneficial for the treatment of ASD and associated psychopathology and cognitive dysfunction in intellectually capable adults. Future placebo-controlled trials are warranted.

    An open label clinical trial was conducted to determine the effectiveness of a multi-ingredient anti-aging moisturizer designed to improve the appearance of facial skin. Parameters studied included fine lines and wrinkles, clarity/brightness, visual roughness, tactile roughness, evenness of skin tone (redness), evenness of skin tone (hyperpigmentation) and overall appearance. Thirty-seven female subjects, ages 35-60 years completed the study. Effective ingredients incorporated into the facial anti-aging moisturizer include: Astragalus membranaceus root extract, a peptide blend including palmitoyl tripeptide-38, standardized rosemary leaf extract (ursolic acid), tetrahexyldecyl ascorbate (THD ascorbate) and ubiquinone (coenzyme Q10). Subjects were instructed to apply the moisturizer twice daily, once in the morning and once in the evening. Subjects were evaluated at baseline and after 4, 8, and 12 weeks of product usage. Clinical evaluations were conducted at each visit. A self-assessment questionnaire was conducted at week 4, week 8, and week 12. The self-assessment questionnaire included product efficacy inquiries and product aesthetic inquiries. Digital photography was conducted at baseline, week 8, and week 12. After 8 weeks of twice daily use, clinical evaluation results show that the multi-ingredient anti-aging moisturizer produced a statistically significant improvement in the scores of all clinical grading parameters assessed compared to baseline. A greater statistically significant improvement was seen at 12 weeks. At week 12, there was a statistically significant percentage of favorable results versus unfavorable results in all product efficacy and product aesthetic self-assessment questionnaire results. Digital photography supported the clinical grading and self-assessment questionnaire results. Additionally, the multi-ingredient anti-aging moisturizer is judged to be mild and well tolerated. Several tolerability parameters were assessed at all time

    An adjuvanted recombinant subunit candidate vaccine (HZ/su) containing varicella zoster virus envelope glycoprotein E was developed for the prevention of herpes zoster and its complications. This study evaluated safety and reactogenicity of HZ/su in an ethnic Japanese population. This was a phase I, open-label and single-center study conducted between March and November of 2010 in Australia. Twenty healthy ethnic Japanese subjects, aged 18-30 y and 50-69 y (1:1) were enrolled. Subjects were administered two doses of HZ/su vaccine according to a 0, 2-mo schedule. Local and general solicited symptoms were recorded for 7 d post-vaccination. Unsolicited symptoms were recorded for 30 d post-vaccination. Serious adverse events (SAEs), new onset of autoimmune disease (NOAD), other potential immune mediated disorders and HZ cases were recorded throughout the study period. All 20 subjects were included in the according-to-protocol cohort for safety. A total of 18 subjects were included in the according-to-protocol cohort for immunogenicity: 10 in the 18-30 y age group and 8 in the 50-69 y age group. The most commonly reported local and general solicited symptoms were pain and fatigue in both groups. Back pain (in the 18-30 y age group) and chills (in the 50-69 y age group) were the most frequently reported unsolicited symptoms. There were no reports of death, SAEs, NOADs, other autoimmune mediated inflammatory disorder or suspected HZ cases. This study indicated that the two-dose regimen of HZ/su exhibited a clinically acceptable safety profile in healthy young and older ethnic Japanese adults.

    We evaluated the efficacy and safety of telbivudine (LdT, 600 mg/day) vs control patients (no treatment) in decreasing vertical transmission of HBV, in HBeAg-positive mothers (HBVDNA >6log(10) copies/mL). HBeAg-positive pregnant women either in the second or third trimester were recruited in a prospective, case-control, open-label study, at the Second Affiliated Hospital of the Southeast University, China (February 2008-December 2010). Efficacy (month 7: HBVDNA (+), HBsAg (+) infants) in either the overall group or the treated group and control group was analysed using student's t-test. Infants were followed for at least 1 year. 362 women received LdT (second trimester n = 257; third trimester n = 105) and 92 were untreated. Before delivery, the mean maternal HBVDNA was 2.73, 2.47, 3.34 and 7.94 log10 copies/mL in the overall, second and third trimester treated and control groups, respectively (P < 0.001). At birth, 11.8% of babies overall (43/365), 13.5% (35/259) of those treated in the second trimester, 7.5% of those treated in the third trimester (8/106) and 20.7% (19/92) of untreated infants were HBsAg positive. At month 7, none of the LdT-treated infant had detectable HBVDNA, while eight infants from control mothers were HBsAg positive. Vertical transmission was 0% in LdT treated and 9.3% (8/86) in the control groups (P < 0.001). No difference in the vertical transmission rate was found in mothers treated in the second or third trimester. LdT treatment was safe for mothers and infants, and no congenital deformities were reported.
