Key Inclusion Criteria:
- 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:
- Participants with a history or clinical features consistent with essential tremor, 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 psychosis or hallucinations within the previous 12 months.
- Participants who answer "yes" on the Columbia-Suicide Severity Rating Scale (C-SSRS) 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.

- 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.

Measure Description |
Time Frame |
---|---|---|
Change From Baseline in the Total "On" Time Without Troublesome Dyskinesia Based on the 2-day Average of the Self-completed Home Diary for Motor Function Status (Hauser Diary)
Time Frame: 27 Weeks
|
The Hauser diary (Hauser et al, 2000) assesses participant-defined clinical status over a period of time and provides a tool for assessment of the change in "off" time and "on" time with troublesome dyskinesia (which is a more accurate reflection of clinical response than "off" time alone).
The Hauser diary asks participants to rate their mobility for each 30-minute period and to record their status for the majority of the period in 1 of 5 categories as: "on" time without dyskinesia, "on" time with nontroublesome dyskinesia, "on" time with troublesome dyskinesia, "off" time, or asleep.
The total "on" time without troublesome dyskinesia will be assessed and reported at endpoint.

Change From Baseline in the Movement Disorder Society - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Parts I, II and III Individual Score
Time Frame: 27 Weeks
|
The MDS-UPDRS is a multidimensional scale that assesses the motor and non-motor impacts of PD across 4 parts.
Part I, non-motor aspects of experiences of daily living, comprises 13 items, 6 of which are rated by the physician (Part IA) and 7 of which are rated by the participant (Part IB).
Part II, motor aspects of experiences of daily living, comprises 13 items that are rated by the participant.
Part III, motor examination, comprises 18 items that are assessed by the investigator (resulting in 33 scores by location and lateralization).
Part IV, motor complications, comprises 6 item (3 items for dyskinesia and 3 items for fluctuation) and requires the physician to use historical and objective information to assess dyskinesia and motor fluctuations.
Each item of all the parts will be rated on a scale from 0 to 4 on which 0 = normal, 1=slight, 2=mild, 3=moderate, and 4=severe.
Change from baseline in MDS-UPDRS parts I, II and III Individual score will be assessed.
