Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Treatment Emergent Adverse Events (TEAEs)	An AE is any untoward medical occurrence in a participant or clinical trial participant, temporally associated with the use of trial intervention, whether or not considered related to the trial intervention. Any AE occurring following the start of treatment or occurring before treatment but increasing in severity afterward were counted as treatment-emergent AE (TEAE). Clinically significant abnormalities in Clinical Laboratory Evaluations, Vital Signs, Physical and Neurological evaluations and ECGs will be reported as TEAEs.	62 Weeks
Primary	Number of Participants Who Discontinued Study Treatment	A participant may discontinue the study treatment due to any of the following reasons: adverse event, death, worsening of PD symptoms to such an extent that, in the judgement of the investigator, the participant requires additional anti-PD medications, treatment with a prohibited concomitant medication, noncompliance with the trial schedule or procedures, withdrawal of consent, pregnancy, investigator discretion.	62 Weeks
Primary	Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease Rating Scale (QUIP-RS)	QUIP-RS is a global screening instrument that assesses impulse control disorders (ICDs) and related disorders (punding, hobbyism, and dopamine dysregulation syndrome) in participants with PD. The QUIP-RS has 4 primary questions that pertain to commonly reported thoughts, urges/desires, and behaviors associated with ICDs, each of which is applied to 4 ICDs (compulsive gambling, buying, eating, sexual behavior) and 3 related disorders (medication use, punding, and hobbyism). The QUIP-RS uses a 5-point Likert scale (score 0-4 [0 means "never" and 4 means "very often"] for each question) to gauge the frequency of behaviors. Scores for each ICD and related disorder range from 0 to 16, with a higher score indicating greater severity (frequency) of symptoms. The total QUIP-RS score for all ICDs and related disorders combined ranges from 0 to 112.	58 Weeks
Primary	Epworth Sleepiness Scale (ESS)	ESS is a scale that is intended to measure daytime sleepiness. It assesses the likelihood of dozing off or falling asleep in the following common situations: sitting and reading, sitting inactive in a public place as a passenger in a car for an hour or more without stopping for a break, lying down to rest when circumstances permit, sitting and talking to someone, sitting quietly after a meal without alcohol, and in a car while stopped for a few minutes in traffic or at a light. Each situation is rated as 0 = would never nod off, 1 = slight chance of nodding off, 2 = moderate chance of nodding off, or 3 = high chance of nodding off. A score greater than or equal to (> =) 10 indicates that the participant may need to get more sleep, improve sleep practices, or seek medical attention to determine why he or she is sleepy.	58 Weeks
Primary	Columbia-Suicide Severity Rating Scale (C-SSRS)	C-SSRS rates an individual's degree of suicidal ideation (SI) on a scale, ranging from "wish to be dead" to "active suicidal ideation with specific plan and intent." The scale identifies SI severity and intensity, which may be indicative of an individual's intent to commit suicide. C-SSRS SI severity subscale ranges from 0 (no SI) to 5 (active SI with plan and intent).	60 Weeks
Primary	Study Medication Withdrawal Questionnaire (SMWQ)	SMWQ is a questionnaire to assess withdrawal symptoms subsequent to completion of dosing with Investigational medicinal product (IMP). The SMWQ is a modification of the Amphetamine Withdrawal Questionnaire, in which the first question "Have you been craving amphetamine or methamphetamine?" is replaced with "Have you been craving the trial medication?" This change is intended to prevent bias by implying that the trial medication might be an amphetamine or amphetamine-like stimulant when presented with the survey. Participants will complete the SMWQ onsite when they are at a designated trial visit; on days when the participant is not onsite, they will complete the SMWQ remotely.	60 Weeks
Primary	Change From Baseline in the Movement Disorder Society - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Parts I, II and III	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 combined score will be assessed.	60 Weeks
Primary	Change From Baseline in the Hauser diary	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.	58 Weeks
Primary	Change From Baseline in the EuroQol 5 Dimension 5 Level (EQ-5D-5L) Index	EQ-5D-5L is a survey instrument used for participant-reported outcome that measures health in 5 dimensions. The EQ-5D-5L descriptive system comprises of 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each has 5 levels of perceived problems (1 = no problem, 2 = slight problems, 3 = moderate problems, 4 = severe problems, 5 = extreme problems). Participant selects an answer for each of 5 dimensions considering the response that best matches his/her health "today". The digits for the 5 dimensions are combined into a 5-digit number that describes the participant's health state.	Baseline (Day 1), Weeks 32 and 58
Primary	Change From Baseline in the EuroQol 5 Dimension 5 Level (EQ-5D-5L) Visual Analog Scores (VAS)	EQ-5D-5L VAS is a 2-part instrument for use as a measure of health outcome, designed for self-completion by respondents. The EQ-5D-5L VAS self-rating records the respondent's own assessment of his or her overall health status at the time of completion, on a scale of 0 (the worst health you can imagine) to 100 (the best health you can imagine).	Baseline (Day 1), Weeks 32 and 58
