Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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.
