  5. Hoehn and Yahr (H&Y) Stage I or II in OFF medication state at screening and prior to randomization
  6. Dopamine transporter imaging with single photon emission computed tomography (DaT-SPECT) imaging consistent with dopamine transporter deficit, as assessed by the central reader
  7. No anticipated changes in PD medication from baseline throughout the study duration based on clinical status during screening
  8. Willingness and ability to use a smartphone application to measure PD-related symptoms for the duration of the study
  9. Willingness and ability to wear a smartwatch to measure PD-related motor signs
  1. Medical history indicating a Parkinsonian syndrome other than idiopathic PD
  2. Diagnosis of PD dementia
  3. Diagnosis of a significant neurologic disease other than PD
  4. Within the last year, unstable or clinically significant cardiovascular disease
  5. Uncontrolled hypertension
  6. Drug and/or alcohol abuse within 12 months prior to screening, in the investigator's judgment (Nicotine is allowed, Marijuana use is not allowed)
