What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Patient's change from baseline of score as measured by Movement Disorder Society-Sponsored Unified Parkinson's Disease Rating Scale Part III (MDS-UPDRS; Part III), after 12 weeks of IPT803 administration.	Part III of the MDS-UPDRS (or motor examination) assesses the motor abilities in PD patients at the time of the visit. This part measures 18 motor examinations such as speech, facial expression, tremor, rigidity, finger tapping, pronation-supination movements of hands, leg agility, arising from chair, gait. The qualified rater must score 34 items from 0 to 4, where 0 indicates a normal situation and 4 indicates that PD interferes severely in carrying out the task. The total score, being the sum of all these items, can be between 0 to 136.	Time zero equals baseline equals (Visit 2 - Day 1 prior to IPT803 first dose) up to Visit 4 (Day 85)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Patient's change from baseline of safety incidence as measured by the rate and severity of Treatment emergent adverse event (TEAEs).		Time zero equals baseline Visit 2 IPT803 first dose (Day 1) up to Visit 4 (Day 85)
Patient's change from baseline of motor and non-motor outcomes as measured by Part I, Part II and IV subscales of Movement Disorder Society-Sponsored Unified Parkinson's Disease Rating Scale (MDS-UPDRS).	The MDS-UPDRS is divided into 4 parts. In each part, all items are rated on a scale from 0 (normal) to 4 (severe impairment). Part I assesses 15 items of non-motor aspects of experiences of daily living. Part IA is assessed by a qualified rater, Part IB is completed by the patient. The total score, being the sum of all these items, can be between 0 to 60. Part II comprises 13 items evaluating the impact of PD on patients' activities of daily living (ADL) over the week prior to the visit such as speech, salivation, swallowing, eating, handwriting, dressing, turning in bed, walking. It will be completed by the patient. The total score, being the sum of all these items, can be between 0 to 52. Part IV assesses motor complications of therapy, such as dyskinesias, motor fluctuations. This part (6 items) is completed by a qualified rater. The total score, being the sum of all these items, can be between 0 to 24.	From Visit 1 (Day -14 to Day -7) up to Visit 4 (Day 85)
The patient's change from baseline in disease severity as measured by the Parkinson's Disease Questionnaire (PDQ-39).		From Visit 2 (Day 1) up to Visit 4 (Day 85)
Patient's change from baseline of fatigue as measured by the Fatigue Severity Scale (FSS).	The FSS is a self-administered questionnaire with 9 items assessing the severity of fatigue during the past 2 weeks. Grading of each item ranges from 1 to 7, where 1 indicates strong disagreement and 7 strong agreement, where the addition of all numbers circled by patient get the final score.	From Visit 1 (Day -14 to Day -7) up to Visit 4 (Day 85)
Patient's change from baseline of sleep quality as measured by the Epworth Sleep Scale (ESS).	The ESS assesses the overall level of daytime sleepiness. Eight items describe normative daily situations known to vary in their soporific qualities. Patients rate the likelihood of dozing off or falling asleep. The test is rated on a 4-point scale (0=would never doze off to 3=high chance of dozing off).	From Visit 1 (Day -14 to Day -7) up to Visit 4 (Day 85)
Investigator change from baseline in disease severity as measured by the Investigator Assessment of Changes (IGAC).	IGAC is a subjective evaluation by the Investigator using a 0 to 10 Numeric Rating Scale (NRS) to answer the following question: "If you take into consideration all the various ways that motor control influences the patient and his/her life, how do you then evaluate the patient's motor condition today?", with 0 meaning "very bad" and 10 "very good".	From Visit 2 (Day 1) up to Visit 4 (Day 85)
Patient's change from baseline in disease severity as measured by the Patient Assessment of Changes (PGAC).	PGAC is a subjective evaluation by the patient using a 0 to 10 Numeric Rating Scale (NRS) to answer the following question: "If you take into consideration all the various ways that motor control influences you and your life, how do you then evaluate your motor condition over the last week?", with 0 meaning "very bad" and 10 meaning "very good".	From Visit 2 (Day 1) up to Visit 4 (Day 85)
Patient's change from baseline above or equal to the minimal clinically important difference (MCID) of the motor score as measured by Part II and III subscales of Movement Disorder Society-Sponsored Unified Parkinson's Disease Rating Scale (MDS-UPDRS).	The Minimal Clinically Important Difference (MCID) is the smallest change in an outcome measure that is meaningful for patients. In the literature, the MCIDs of MDS-UPDRS Part II and Part III are respectively defined as a motor score reduction of 2 and 6 points. The motor scores are the sum of all items (ranging from 0-4) of each MDS-UPDRS subscale. Following endpoints will be measured: A reduction above or equal to 2 points of MDS-UPDRS Part II motor score (minimum score= 0, maximal score= 52); A reduction above or equal to 6 points of MDS-UPDRS Part III motor score (minimum score= 0, maximal score= 136) These endpoints will be interpreted as binary values: 0 (below) and 1 (above or equal).	Time zero equals baseline (Visit 2 - Day 1 prior to IPT803 first dose) up to Visit 4 (Day 85)
Patient's change from baseline above or equal to 30 % or above or equal to 50 % of the motor score as measured by Part II and III subscales of MDS-UPDRS.	The motor scores are the sum of all items (ranging from 0-4) of each MDS-UPDRS subscale. Following endpoints will be measured: A reduction above or equal to 30% of MDS-UPDRS Part II motor score; A reduction above or equal to 30% of MDS-UPDRS Part III motor score; A reduction above or equal to 50% of MDS-UPDRS Part II motor score; A reduction above or equal to 50% of MDS-UPDRS Part III motor score These endpoints will be interpreted as binary values: 0 (below) and 1 (above or equal).	Time zero equals baseline (Visit 2 - Day 1 prior to IPT803 first dose) up to Visit 4 (Day 85)
Cronbach α assessment of MPsQ		at Visit 1 (Day -14 to Day -7), Visit 2 (Day 1) Visit 4 (Day 85)

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Patient's change from baseline of motor score, as measured by Inertial Measurement Unit (IMU) on Finger taping (FT) and Pronation-supination movement of the hands (PSH) during the 12-week treatment.	For all patients, objective quantitative movement will be collected with movement sensors (accelerometers and gyroscopes) during items 3.4 (FT) and 3.6 (PSH) of MDS-UPDRS Part III at Visits 2, 3 and 4. Collected data will be converted to continuous values on the same scale as MDS-UPDRS, from 0 to 4. The endpoint is defined as the patient's change from baseline of these continuous scales.	Time zero equals baseline equals (Visit 2 - Day 1 prior to IPT803 first dose) up to Visit 4 (Day 85)
Patient's change from baseline of the regional brain activity as measured by BOLD fMRI measured by motor tasks performed during fMRI before and after single dose of IPT803.		On Day 1: prior to IPT 803 first dose and 60 minutes after IPT803 first dose
Patient's change of motor score, as measured by Part III subscale of MDS-UPDRS directly after IPT803 single dose.	The qualified rater must score 34 items from 0 to 4, where 0 indicates a normal situation and 4 indicates that PD interferes severely in carrying out the task. The total score, being the sum of all these items, can be between 0 to 136.	On Day 1: prior to IPT 803 first dose and 30 minutes after IPT803 first dose
