3. Has current evidence of an unstable neurological, cardiovascular, respiratory, gastrointestinal, renal, hepatic, hematologic, or other medical or psychiatric disorder, including cancer or malignancies that, in the judgment of the Investigator, would jeopardize the safe participation of the subject in the study or significantly interfere with the conduct or interpretation of the study
4. Has a history of myocardial infarction, unstable angina, acute coronary syndrome, or cerebrovascular accident within the last 6 months prior to Screening
5. Has any of the following:

7. Requires treatment with a medication or other substance that is prohibited by the protocol
8. Has a body mass index (BMI) \<18.5 kg/m2 or \>35 kg/m2 at Screening or Baseline or known unintentional clinically significant weight loss (i.e., ≥7%) over past 6 months
9. Is suicidal at Screening or Baseline
10. Has a history of a significant psychotic disorder prior to or concomitantly with the onset of PD including, but not limited to, schizophrenia or bipolar disorder
11. Had dementia prior to or concomitantly with the onset of motor symptoms of PD
12. Positive COVID-19 polymerase chain reaction (PCR) or antigen result in the last 2 weeks prior to screening
