Netakimabis original monoclonal antibody against IL-17. This article outlines the key results of a phase II open-label extension trial of netakimab 80 mg and 120 mg in patients with moderate-to-severe psoriasis.The main aim of the trial is to estimate efficacy, safety and immunogenicity of long-term treatment with netakimab 80 mg and 120 mg in patients with moderate-to-severe psoriasis.Materials and methods. The BCD-085-2-ext study is a comparative, open-label phase 2 clinical study of the effi - cacy and safety of netakimab in patients with moderate-to-severe plaque psoriasis who had finished BCD-085-2 (NCT02762994) trial. Main efficacy endpoints includePASI75, PASI90, PASI100, sPGA = 0–1 on week 38 of the trial, long-term PASI75/90/100 retention, efficacy keeping after switch from once every 2 week regimen to once every 4 week regimen. Safety endpoints include adverse events, serious adverse events number and their profile.Results. 103 patients were included. PASI75 at week 38 was reached by 98.06 %, PASI90 — by 92.23 %, PASI100 — by 59.22 % of patients. There were no cases of serious adverse event, early with drawal due to adverse events and cases of grade 4 toxicity according to CTCAE 4.03. There were no cases of binding antibodies to netakimab during the 38 weeks of the study.Conclusion. The first Russian original IL-17 inhibitor netakimabis promising modern medicine for moderate-to-severe plaque psoriasis treatment. Netakimabshowed high efficacy, favorable safety profile and low immunogenicity during one year of the treatment.

ABSTRACTIntroduction:Guanfacine is a noradrenergic agonist that is believed to improve symptoms of attention-deficit/hyperactivity disorder (ADHD) through selective actions at α2A-adrenoceptors in the prefrontal cortex. A recent double-blind, multicenter trial supports the efficacy and safety of guanfacine extended release (GXR) for pediatric ADHD. This long-term, open-label extension was conducted to study the safety profile and effectiveness of GXR for up to 2 years.Methods:Subjects were 240 children 6–17 years of age with a diagnosis of ADHD who participated in the preceding randomized trial. GXR was initiated at 2 mg/day and titrated as needed in 1-mg increments to a maximum of 4 mg/day to achieve optimal clinical response.Results:The most common adverse events were somnolence (30.4%), headache (26.3%), fatigue (14.2%), and sedation (13.3%). Somnolence, sedation, and fatigue were usually transient. Cardiovascular-related adverse events were uncommon, although small reductions in mean blood pressure and pulse rate were evident at monthly visits. ADHD Rating Scale, Version IV, total and subscale scores improved significantly from baseline to endpoint for all dose groups (P<.001 for all comparisons, intent-to-treat population).Conclusion:Long-term treatment with GXR was generally safe for up to 24 months of treatment, and effectiveness was maintained over this treatment period.

The TOMORROW trial of nintedanib comprised a randomised, placebo-controlled, 52-week period followed by a further blinded treatment period and an open-label extension. We assessed outcomes across these periods in patients randomised to nintedanib 150 mg twice daily or placebo at the start of TOMORROW. The annual rate of decline in FVC was −125.4 mL/year (95% CI −168.1 to −82.7) in the nintedanib group and −189.7 mL/year (95% CI −229.8 to −149.6) in the comparator group. The adverse event profile of nintedanib remained consistent throughout the studies. These results support a benefit of nintedanib on slowing progression of idiopathic pulmonary fibrosis beyond 52 weeks.

Abstract:Background:In the 12-week ARM-TD and AIM-TD studies evaluating deutetrabenazine for the treatment of tardive dyskinesia (TD), the percentage of patients achieving ≥50% response was higher in the deutetrabenazine-treated group than in the placebo group. These studies also showed low rates of overall adverse events (AEs) and discontinuations associated with deutetrabenazine. The current open-label study evaluated the long-term efficacy and safety of deutetrabenazine in patients with TD.Methods:Patients with TD who completed ARM-TD or AIM-TD could enroll in this open-label, single-arm extension study, titrating up over 6 weeks to a maximum total daily dose of deutetrabenazine 48 mg/day on the basis of dyskinesia control and tolerability. The proportion of Abnormal Involuntary Movement Scale (AIMS; items 1-7) responders was assessed based on response rates for achieving ≥50% improvement from baseline in the open-label extension study. AlMS score was assessed by local site raters for this analysis.Results:343 patients enrolled in the extension study. At Week 54 (n=249; total daily dose [mean ± standard error]: 38.6±0.66 mg), the mean percentage change from baseline in AIMS score was –40%; 48% of patients achieved a ≥50% response and 59% of those had already achieved a ≥50% response at Week 15. Further, 34% of those who had not achieved a ≥50% response at Week 15 achieved a ≥50% response at Week 54. At Week 106 (n=169; total daily dose: 39.6±0.77 mg), the mean percentage change from baseline in AIMS score was –45%; 55% of patients achieved a ≥50% response, 59% of those patients had already achieved a ≥50% response at Week 15, and 41% of those who had not achieved a ≥50% response at Week 15 but who reached Week 106 achieved a ≥50% response. At Week 132 (n=109; total daily dose: 39.7±0.97 mg), the mean percentage change from baseline in AIMS score was –61%; 55% of patients achieved a ≥50% response, 61% of those patients had already achieved a ≥50% response at Week 15, and 43% of those who had not achieved a ≥50% response at Week 15 but who reached Week 132 achieved a ≥50% response. Completer analysis suggests that long-term efficacy was not due to dose increases over time. Treatment with deutetrabenazine was generally well tolerated. There were 623 patient-years of exposure through Week 158, and exposure-adjusted incidence rates (incidence/patient-years) of adverse events of special interest were 0.01 for akathisia and restlessness, 0.07 for somnolence and sedation, 0.04 for parkinsonism, and 0.05 for depression.Conclusions:Patients who received long-term treatment with deutetrabenazine achieved response rates that were indicative of clinically meaningful long-term benefit. Results from this open-label trial suggest the possibility of increasing benefit over time with individual dose titration of deutetrabenazine.Funding Acknowledgements:This study was funded by Teva Pharmaceuticals, Petach Tikva, Israel.
