简要总结
The main purpose of this study is to evaluate the efficacy of JNS001 titrated to daily doses of 18 to 72 mg in adults with attention-deficit hyperactivity disorder (ADHD) relative to placebo.
详细描述
This is a randomized (the study drug is assigned by chance), double-blind (DB, neither physician nor patient knows the name of the assigned drug), multicenter, placebo-controlled, parallel group (each group of patients will be treated at the same time), dose-titration study. This study consists of a screening period, a DB phase (titration period and efficacy assessment period), and post-study phase. The study includes a 1 to 2-week screening period for wash-out of prohibited drugs, and screening for eligibility. Eligible patients will be randomly assigned to receive JNS001 or placebo in a ratio of 1:1. The study also includes a 4-week titration period. Patients will be titrated from a starting dose of 18 mg/day or matching placebo for 7 days (+/- 2 days), and continue with a weekly (+/- 2 days) increment of 18 mg until an individualized dose is achieved. Once an individualized dose is achieved, patients will remain on that dose for the rest of the titration period as far as tolerable. Doses can be tapered down only once during the titration period in the study, and their dose cannot be up-titrated again for the rest of the period. The 4-week titration period will be followed by the 4-week efficacy assessment period. The post-study phase for collection of additional safety data will be scheduled for 1 week after a patient's final study treatment. The study drug will be administered with water once daily in the morning at doses of 18 mg, 36 mg, 54 mg, 72 mg per day or the matching placebo. The study treatment period is 8 weeks (titration period of 4 weeks and efficacy assessment period of 4 weeks).

主要结局
Change From Baseline to Endpoint in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) Total Attention Deficit-Hyperactivity Disorder (ADHD) Symptoms Scores of Conners' Adult ADHD Rating Scale - Observer Screening Version (CAARS-O: SV)
时间窗: Baseline (Day 0) to Endpoint (Week 8)
CAARS-O: SV evaluates DSM-IV-oriented inattention, impulsivity and hyperactivity as well as measures of self-concept. The CAARS-O:SV comprises 30 items to measure symptoms for ADHD in adults. Each item is scored from 0 (not at all, never) to 3 (very much, very frequently) with higher scores corresponding to worse symptoms. The total score can range from 0 (best) to 90 (worst). Lower score indicates improvement in ADHD symptoms.
