Introduction: Rotigotine was demonstrated to be efficacious and well-tolerated in three placebo-controlled studies (CLEOPATRA-PD/PREFER/SP921) of patients with advanced-stage Parkinson's disease (PD), most of whom were Caucasian. This multicenter phase 3 study (SP1037; NCT01646255) was the first to investigate the efficacy and safety of rotigotine in Chinese patients with advanced-stage PD. Methods: Chinese patients with PD, inadequately controlled on levodopa (stable dose >= 200 mg/day), with >= 2.5 h/day off time, and Hoehn & Yahr stage 2-4, were randomized 1:1 to receive transdermal rotigotine or placebo, titrated over <= 7 weeks, maintained at optimal/maximum dose (4-16 mg/24 h) for 12 weeks. Primary efficacy variable: mean change in absolute off time (according to patient diaries) from baseline to end of maintenance. Safety variables included adverse events (AEs) and discontinuations due to AEs. Results: 346 patients were randomized and 89.9% completed the study (87.8% placebo; 92.0% rotigotine). All were Chinese (58.7% male; mean +/- SD age: 62.2 +/- 8.9 years; mean +/- SD time since PD diagnosis: 6.62 +/- 3.70 years). Rotigotine significantly reduced off time vs placebo (LS mean [95% CI] treatment difference: -1.20 h/day [-1.83, 0.57]; p = 0.0002), and resulted in more responders (>= 30% decrease in off time: 36.9% placebo; 48.8% rotigotine; p = 0.0269). AEs were reported for 86 (50.0%) placebo- and 103 (59.2%) rotigotine-treated patients; 15 discontinued due to AEs (placebo 7; rotigotine 8). The most common AEs (>= 5%) were dizziness, nausea, pruritus, and dyskinesia. Conclusions: Rotigotine was efficacious in Chinese patients with advanced-stage PD as add-on therapy to levodopa, significantly reducing off time vs placebo; the treatment difference was similar to that observed in previous studies of mainly Caucasian patients. Rotigotine was generally well-tolerated and had a similar AE profile to those observed in previous studies. (C) 2017 Elsevier Ltd. All rights reserved.
