9.Subjects 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 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.

| E.4 | Principal exclusion criteria |
1.Subjects 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).
2.Subjects with a history of nonresponse or insufficient response to L Dopa at therapeutic dosages.
3.Subjects who have had previous surgical intervention (eg, deep brain stimulation) for PD or for whom such a procedure is planned or anticipated during the trial period.
4.Subjects with an acute or chronic, clinically significant medical or psychiatric condition, cognitive impairment, or laboratory abnormality that might increase the risk associated with trial participation or administration of trial treatment or interfere with the interpretation of the trial results or that, in the judgment of the investigator, would make the subject inappropriate for entry into this trial. Medical conditions that are minor or well controlled may be considered acceptable if the condition does not expose the subject to an undue risk of a significant AE or interfere with the assessments of safety or efficacy during the course of the trial. Subjects with symptoms of anxiety or depression that are not debilitating and that are stable or adequately controlled with non-prohibited medication are considered acceptable. The medical monitor should be contacted in any instance where the investigator is uncertain regarding the stability of a subject’s medical conditions(s) and the potential impact of the condition(s) on trial participation.
5.Subjects with a history or current diagnosis of a clinically significant impulse control disorder (Disruptive, Impulse Control, and Conduct Disorder per DSM 5)
6.Subjects with the presence of or history of brain tumor, hospitalization for severe head trauma, epilepsy (as defined by the International League Against Epilepsy), or seizures.

Subjects who, in the opinion of the investigator, present a serious risk of suicide.
9.Subjects with substance abuse or dependence disorder, including alcohol, benzodiazepines, and opioids, but excluding nicotine, within the past 6 months (180 days).
10.Subjects with dementia or cognitive impairment that, in the judgement of the investigator, would exclude the subject from understanding the ICF or participating in the trial.
11.Subjects with any condition that could possibly affect drug absorption, including bowel resections, bariatric weight loss surgery, or gastrectomy (this does not include gastric banding).
12.Subjects who have a positive result for HIV antibodies, HbsAg, or HCV antibodies at screening.
13.Subjects with a history of malignancy other than:
• Non-metastatic basal or squamous cell carcinoma of the skin or carcinoma in situ that was surgically removed in total >1 year before signing the ICF and had not recurred
• Another type of malignancy that had been in remission for =5 years before signing the ICF and had not recurred
