Rotigotine Versus Placebo As Double Blind Study To Evaluate The Efficacy In Early Stage Idiopathic Parkinson's Disease Patients

A Multicenter, Randomized, Double-blind, Parallel-group, Placebo-controlled Study Of The Efficacy And Safety Of The Rotigotine Transdermal Patch In Chinese Subjects With Early-stage Idiopathic Parkinson's Disease

The primary objective is to demonstrate that the Rotigotine transdermal patch is efficacious in Chinese subjects with early-stage idiopathic Parkinson's disease.

The study includes a maximum 4-week Screening Period, a maximum 4-week Titration Period for early-stage Parkinson's disease 24-week Maintenance Period, a maximum 6-day De-escalation Period and 30-day Safety Follow-Up Period. The maximum study durations for an individual subject with early-stage Parkinson's disease will be 36 weeks.

• Subject is currently receiving central nervous system (CNS) active therapy (eg, sedatives, hypnotics, antidepressants, anxiolytics), unless the dose has been stable for at least 28 days prior to Baseline Visit (Visit 2) and is likely to remain stable for the duration of the study
• Subject has a current diagnosis of Epilepsy, has a history of seizures as an adult, has a history of stroke, or has had a transient ischemic attack within 1 year prior to Screening (Visit 1)
