up to 6 years
Dose levels will be individually optimized
- Number of Participants with Adverse Events [ Time Frame: From Day 1 up to 6 years (estimated maximum) ]All negative changes in health during the study will be treated and recorded during the study.
- Change in Patient Global Impression of Change (PGIC) scores [ Time Frame: From Screening Visit 2 of M12-921 to Week 52 of M12-923 ]The PGIC is a 7-point response scale. The subject will be asked by the Investigator or qualified designee to rate their change in their disease status.
- Change in the Unified Parkinson's Disease Rating Scale (UPDRS) score [ Time Frame: From Day 1 up to 36 months (estimated maximum) ]The Unified Parkinson's Disease Rating Scale (UPDRS) is an Investigator-used rating tool to follow the course of Parkinson's disease.
- Change in the Parkinson's Disease Questionnaire-39 (PDQ-39) scores [ Time Frame: From Screening Visit 2 of M12-921 to Week 52 ]The PDQ-39 is a disease-specific instrument designed to measure aspects of health that are relevant to subjects with PD, and which may not be included in general health status questionnaires.
- Change in PD Diary mean daily "On" time without troublesome dyskinesia ("On" time without dyskinesia or with non-troublesome dyskinesia) or "On" time with troublesome dyskinesia [ Time Frame: From Day 1 to Week 52 ]The study will assess the difference in the amount of time a subject is able to move and function well during the day.
- Change in the mean daily "Off" time (hours) as measured by the Parkinson's Disease (PD) Diary © [ Time Frame: From Day 1 to Week 52 ]The study will assess the difference in the amount of time a subject is unable to move and function during the day.
- Change in Clinical Global Impression of Change (CGI-C) scores [ Time Frame: From Screening Visit 2 of M12-921 to Week 52 of M12-923 ]The 7-item CGI-C (Change) scale assesses the overall degree of illness relative to Week 0. A rating of 4 is equivalent to "no change." Ratings < 4 are equivalent to "improvement" and ratings of 4 are equivalent to "worsening."
