Eligibility
Key inclusion criteria
Key

- Male and female participants aged 40 to 80 years, inclusive, at the time of signing
the informed consent form (ICF).

- Sexually active men or women of childbearing potential must agree to use acceptable
(at minimum) or highly effective birth control, or remain abstinent during the trial
and for 4 weeks after the last dose of trial treatment.

- Participants who are capable of giving signed informed consent which includes
compliance with the requirements and restrictions listed in the ICF and in this
protocol.

- Participants with a diagnosis of PD that is consistent with the UK Parkinson's Disease
Society Brain Bank diagnostic criteria, with bradykinesia and motor asymmetry.

- Participants with modified Hoehn and Yahr stage 2, 2.5, or 3 in the "on" state.

- Participants with a good response to levodopa (L-Dopa) in the judgment of the
investigator.

- Participants who return a completed self-reported home diary for motor function status
(Hauser diary) during the screening period (after diary training and concordance
testing has occurred), with recordings for 2 consecutive days (ie, 2 consecutive
24-hour periods) showing at least 2 and half hours of "off" time on each of the 2
days.

- Participants who are on a stable dose of L-Dopa for at least 4 weeks prior to
screening and are taking a minimum total daily dose of 400 milligram (mg) divided in
at least 4 doses per day of standard carbidopa/levodopa or divided in at least 3 doses
per day of extended-release carbidopa/levodopa capsules. The carbidopa/levodopa dose
and frequency must be maintained for the duration of the trial.

- Prior and concurrent use of catechol-O-methyl transferase (COMT) inhibitors, monoamine
oxidase B (MAO-B) inhibitors, amantadine, istradefylline or anticholinergic drugs are
permitted if the use was initiated greater than (>) 90 days before the baseline visit
and the dosage will remain stable for the duration of the trial (ie, no change in the
COMT, MAO-B inhibitor, amantadine, istradefylline or anticholinergic dose is permitted
during the trial).

Key exclusion criteria

atypical or secondary parkinsonian syndrome (including, but not limited to,
progressive supranuclear palsy, multiple system atrophy, cortico-basal degeneration,
or drug-induced or poststroke parkinsonism).

- Participants with a history of nonresponse or insufficient response to L-Dopa at
therapeutic dosages.

- Participants with a history or current diagnosis of a clinically significant impulse
control disorder (Disruptive, Impulse Control, and Conduct Disorder per DSM-5).

severe head trauma, epilepsy (as defined by the International League Against
Epilepsy), or seizures.

- Participants with a history of psychosis or hallucinations within the previous 12
months.

Suicidal Ideation Item 4 or Item 5 (Active Suicidal Ideation with Some Intent to Act,
Without Specific Plan, or Active Suicidal Ideation with Specific Plan and Intent) and
whose most recent episode meeting the criteria for C-SSRS Item 4 or Item 5 occurred
within the last 6 months, OR Participants who answer "yes" on any of the 5 C-SSRS
Suicidal Behavior Items (actual attempt, interrupted attempt, aborted attempt,
preparatory acts, or behavior) and whose most recent episode meeting the criteria for
any of these 5 C-SSRS Suicidal Behavior Items occurred within the last 2 years, OR
Participants who, in the opinion of the investigator, present a serious risk of
suicide.

- Participants with substance abuse or dependence disorder, including alcohol,
benzodiazepines, and opioids, but excluding nicotine, within the past 6 months (180
days).

- Participants with dementia or cognitive impairment that, in the judgement of the
investigator, would exclude the participant from understanding the ICF or
participating in the trial.

- Participants with any condition that could possibly affect drug absorption, including
bowel resections, bariatric weight loss surgery, or gastrectomy (this does not include
gastric banding).

- Participants who have a positive result for human immunodeficiency virus (HIV)
antibodies, hepatitis B surface antigen (HbsAg), or hepatitis C virus (HCV) antibodies
at screening.

ventricular arrhythmias that are not controlled with medical and/or surgical
intervention; second- or third-degree atrioventricular block; sick sinus syndrome;
severe or unstable angina; or congestive heart failure within the last 12 months. A
recent (less than or equal to [<=12] months) history of myocardial infarction with
secondary arrhythmias is exclusionary regardless of the therapeutic control.

- Participants with a history of neuroleptic malignant syndrome.

- Participants who are currently receiving moderate or strong CYP3A4 inducers or CYP3A4
inhibitors (except for topical administration).

- Participants with a positive urine drug screen for illicit drugs are excluded and may
not be retested or rescreened. Participants with a positive urine drug screen
resulting from use of marijuana (any tetrahydrocannabinol-containing product),
prescription, or over-the-counter medications or products that, in the investigator's
documented opinion, do not signal a clinical condition that would impact the safety of
the participant or interpretation of the trial results may continue evaluation for the
trial following consultation and approval by the medical monitor

- Participants with a Montreal Cognitive Assessment (MoCA) score <26.

- Participants with clinically significant orthostatic hypotension (eg, syncope).

- Participants with a 12-lead ECG demonstrating a QTcF interval >450 msec.

- Participants with moderate or severe renal impairment (creatinine clearance as
estimated by Cockcroft-Gault formula <30 mL/min or on dialysis).

- Participants with any of the following abnormalities in clinical laboratory tests at
the Screening Visit, as assessed by the central laboratory and confirmed by a single
repeat measurement, if deemed necessary:

- Aspartate Aminotransferase (AST) or Alanine Aminotransferase (ALT) >=3 × Upper
Limit Normal (ULN).

- Total bilirubin >=1.5 × ULN. Participants with a history of Gilbert's syndrome
may be eligible provided they have a value <ULN for direct bilirubin

- Participants with other abnormal laboratory test results, vital sign results, or ECG
findings unless, in the judgment of the investigator, the findings are not medically
significant and would not impact the safety of the participants or the interpretation
of the trial results.
