  • Diagnosis of clinically established or clinically probable PD according to MDS-PD criteria with at least 1 year of PD symptoms.
  • Modified Hoehn and Yahr ≤2.5.
  • Have notable motor worsening during off-medication state.
  • Clear-cut improvement of motor response to levodopa medications, as assessed by the investigator.
  • Must be on stable dopaminergic therapy (e.g., levodopa, dopamine agonists, monoamine oxidase inhibitors, catechol-O-methyl transferase inhibitors, amantadine), for at least 8 weeks prior to enrollment and remain on stable dose during the 12-week treatment period.
  • Female subjects must not be pregnant or breastfeeding. Women of childbearing potential (WOCBP) must have a negative pregnancy test at Screening. WOCBP must agree to use highly effective contraception prior to study entry. Male subjects must be willing to use a barrier method of contraception.

  • History of any brain surgery for PD (e.g., pallidotomy, deep brain stimulation, or fetal tissue transplant).
  • Conditions affecting the peripheral or central nervous system, unless related to PD, that would affect the ability to adequately perform the MDS-UPDRS and motor assessments: i.e., severe sensory neuropathy affecting arm or leg function, or stroke affecting motor or gait function.
  • Significant alcohol or drug abuse within past 2 years.
  • Based on ECG reading, subjects with a risk of QT prolongation.
  • NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.
