Phase 3 Study of CVN424 (Parkinson's Disease)

Purpose of this Study

We are doing this study to find out if an experimental drug called CVN424 (the study drug) can help people diagnosed with advanced Parkinson's Disease (PD) who are on a stable dose of medication and continue to experience three of more hours of "OFF-time." OFF-time is a term that refers to the time when people experience PD symptoms between doses of medicine. We want to know if the study drug can reduce symptoms and lower that amount of time.
