摘要:Background:The use of adjunct rasagiline in levodopa-treated patients with Parkinson’s disease and motor fluctuations is supported by findings from large-scale clinical studies.This study is to investigate the efficacy and safety of adjunct rasagiline in Chinese patients with Parkinson’s disease,as a product registration study.Methods:This 16-week,randomized,double-blind,parallel-group,multicenter,placebo-controlled study of rasagiline 1 mg/day included levodopa-treated patients with Parkinson’s disease and motor fluctuations.The primary efficacy endpoint was mean change from baseline in total daily OFF time over 16 weeks.Secondary endpoints were Clinical Global Impressions–Improvement(CGI-I),and change in Unified Parkinson’s Disease Rating Scale(UPDRS)Activities of daily living(ADL)and Motor scores.Patient well-being(EQ-5D),and the frequency of adverse events were also assessed.Results:In total,324 levodopa-treated patients were randomized to rasagiline 1 mg/day(n=165)or placebo(n=159).Over 16 weeks,rasagiline statistically significantly reduced the mean[95% confidence interval]total daily OFF time versus placebo(−0.5 h[−0.92,−0.07];p=0.023).There were also statistically significant improvements versus placebo in CGI-I(−0.4 points[−0.61,−0.22];p<0.001),UPDRS-ADL OFF(−1.0 points[−1.75,−0.27];p=0.008),and UPDRS-Motor ON(−1.6 points[−3.05,−0.14];p=0.032)scores,as well as the EQ-5D utility index(p<0.05).Rasagiline was safe and well tolerated.Conclusions:In levodopa-treated Chinese patients with Parkinson’s disease and motor fluctuations,adjunct rasagiline 1 mg/day statistically significantly reduced OFF time,and improved daily function and overall well-being,versus placebo.Consistent with findings in other countries,adjunct rasagiline was proven efficacious and well tolerated in Chinese patients.
