This study will evaluate whether an investigational drug called BIIB122 is safe and effective in people with early-stage Parkinson’s disease (PD) who are 30-80 years old. The study also aims to learn how the body handles taking BIIB122 (tolerability), as well as how the body absorbs, processes, and removes the drug (pharmacokinetics). Researchers will examine biomarkers, which are substances that occur naturally in the body that may indicate whether a treatment is working. BIIB122 is designed to affect the activity of a specific protein in the brain and may prevent or delay the development of PD symptoms.
