Eligibility

Inclusion Criteria:

• Male and female adults 45-75 years of age inclusive, at the time of signing of informed consent

• Diagnosed with Parkinson's Disease in the past 4-10 years inclusive defined by the following:

Presence of bradykinesia PLUS any of the following:

Rigidity Rest Tremor Postural instability

• Modified Hoehn and Yahr stage II-III in the practically defined OFF medication state (>/= 12 hours from last dose of anti-parkinsonian medications)

• MDS-UPDRS Part III score in the practically defined OFF state of 33 to 60 (inclusive)

• Stable anti-parkinsonian medication regimen for >/= 4 weeks prior to Screening and held stable throughout the baseline period o Responsiveness to levodopa as determined by change in modified H&Y stage or MDS-UPDRS Part III score from the practically defined OFF state to ON state after taking first daily dose of PD medication

Exclusion Criteria:
