Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Levodopa-induced Dyskinesia as Measured by UDysRS Score

    Mean change from baseline (BL) in the sum of Parts 1, 3 and 4 of the Unified Dyskinesia Rating Scale (UdysRS), in the ON state. The UDysRS comprises 2 primary sections i.e. Historical \[Part 1 (ON-Dyskinesia) and Part 2 (OFF-Dystonia)\] and Objective \[Part 3 (Impairment) and Part 4 (Disability)\] assessment. ON-Dyskinesia are choreic and dystonic movements that occur when the Parkinson's disease (PD) medicine is working. Lower UDysRS values mean better patient outcome i.e. less dyskinesia. The UDysRS score for this study is calculated as sum of the parts, with scores of 0-44 for Part 1, 0-28 for Part 3 and 0-16 for Part 4.

    Baseline; Visit 7 (at Week 16) planned. Since the study was terminated early due to the COVID-19 pandemic, analysis of the primary endpoint was done at Visit 5 (Week 8/10) in those patients who were on study drug at this visit.
