Brief summary
The rationale for conducting this study is to evaluate the efficacy, tolerability, and safety of rasagiline compared to placebo in levodopa-treated Parkinson's Disease (PD) Chinese patients with motor fluctuations. Azilect® (Rasagiline) is indicated for the treatment of idiopathic PD as monotherapy (without levodopa) or as adjunct therapy (with levodopa) in patients with end of dose fluctuations.

Eligibility
Inclusion criteria
* Patients with idiopathic PD. * Patients with motor fluctuations averaging at least 1 hour daily in the OFF state during the waking hours. * Patients with a Modified Hoehn and Yahr stage ≤3 in the ON state. * Patients taking optimised levodopa or dopa decarboxylase inhibitor (DDI) therapy; they must be stable for at least 14 days prior to baseline. * Patients receiving at least 3 daily doses of levodopa and not more than 8 daily doses of levodopa. * Patients who have demonstrated the ability to keep accurate 24-hour diaries prior to randomisation.
Exclusion criteria
* Patients with a clinically significant or unstable medical or surgical condition that would preclude his/her safe and complete study participation. * Patients with a clinically significant or unstable vascular disease. * Patients who have undergone a neurosurgical intervention of PD. * Patients with severe disabling dyskinesias. * Patients with a clinically significant psychiatric illness, including a major depression, which compromises their ability to provide consent or participate fully in the study. * Patients with a Mini Mental State Examination (MMSE) score ≤24. * Patients with a diagnosis of melanoma or a history of melanoma, or a suspicious lesion.

| Change From Baseline in Mean Total Daily OFF Time Using Parkinson's Disease Patient Diary | Baseline and Weeks 4, 8, 12, and 16 | Parkinson's Disease Patient Diary is a self-administered diary designed to assess motor fluctuations throughout the day. It is divided into 30-minute intervals, and the patient selects one of four options for each interval: asleep; off; on with no dyskinesia or without troublesome dyskinesia; or on with troublesome dyskinesia. The Change From Baseline in Mean Total Daily OFF time is calculated by taking the difference between the average of the total daily OFF time at Weeks 4, 8, 12, and 16, and the Baseline Total Daily OFF Time. |

Pre-assignment details
The study consisted of a 2-week Screening Period during which the levodopa dose was optimised (if required), a 2-week Screening Period during which the levodopa dose was stabilised, a 16-week double-blind treatment period with rasagiline or placebo once daily (patients were randomised in a 1:1 ratio), and a 4-week Safety Follow-up Period.
