Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Safety Evaluation: Incidence of serious adverse events of special interest
Time Frame: Baseline to 5 years
Assess severity and frequency serious adverse events of special interest
Baseline to 5 years
Safety Evaluation: Incidence of serious adverse events (SAEs) and adverse events (AEs)
Time Frame: Baseline to 5 years
Assess severity and frequency of reported adverse events
Baseline to 5 years
Safety Evaluation: Number of participants with clinically-relevant changes in physical exams
Time Frame: Baseline to 5 years
The results of the physical examination after administration of the clinical trial drug are compared with those before administration to determine whether clinically significant symptoms occur
Baseline to 5 years
Safety Evaluation: Number of participants with clinically-relevant changes in laboratory test
Time Frame: Baseline to 5 years
The clinical significance of laboratory test results after administration of a clinical trial drug is confirmed by comparing them with those before administration.
Baseline to 5 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change from Baseline in Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) scores (defined on/off)
Time Frame: Baseline to 5 years
Each symptom is rated on a scale of 0 to 4, with higher scores indicating more severe Parkinson's disease.
Baseline to 5 years
