Brief summary

This is a randomized, placebo-controlled, 3-way cross-over phase IIa trial comparing two dose levels of THN102 to placebo in patients suffering from Parkinson's disease associated with excessive daytime sleepiness.

Detailed description

The treatment duration is 2 weeks per period. Each treatment period is followed by a one-week washout period.

Inclusion criteria

* Subjects with a diagnosis of idiopathic Parkinson's disease as defined by the Movement Disorders Society (MDS). * Subjects with Hoehn and Yahr scale score ≤ 4. * Body mass index \> 18 kg/m2 and \< 35 kg/m2. * Subjects should have a complaint of daytime sleepiness impacting their quality of life and/or daytime functioning (e.g. falling asleep while reading or watching television, while eating or talking with other people). * Epworth Sleepiness Scale (ESS) score ≥ 14.

Exclusion criteria

* Subjects with known or with a suspected sleep apnea syndrome or who have any other cause of excessive daytime sleepiness, such as shift work sleep disorder. * Psychiatric and neurological disorders (other than Parkinson's disease), * Cardiovascular disorders such as - but not limited to * Uncontrolled moderate to severe hypertension * History or current diagnosis of electrocardiogram (ECG) abnormalities indicating significant risk of safety for patients participating in the study * Recent myocardial infarction * Stable or unstable angina pectoris * Cardiac insufficiency or history of heart failure * Previous history of cardiac valvular surgery * Subjects with current impulse control disorder. * Subjects showing dementia or with MoCA \< 23. * Subjects with current suicidal risk * Current or recent (within one year) history of substance abuse or dependence disorder * Other active clinically significant illness * Subjects with hepatic or renal impairment
