| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Number of Participants Reporting Treatment Emergent Adverse Events (AEs) for Parts A & B Combined | Day 1 to Week 55 | Adverse events were analyzed for all participants in Parts A \& B combined as one group for this outcome measure. An AE was defined as any untoward medical occurrence that develops or worsens in severity during the conduct of a clinical study and does not necessarily have a causal relationship to the study drug. Incudes clinically significant changes such as changes in vital signs or lab values. Relationship of AE to treatment was determined by the Investigator. Serious AEs include death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, or an important medical event that jeopardized the participant and required medical intervention to prevent the previously listed serious outcomes. A summary of other non-serious AEs and all serious AEs, regardless of causality is located in Reported AE section. |
| Primary | Number of Participants Reporting Treatment Emergent Adverse Events (AEs) in Part B (Period II) | Weeks 28 to 30 | Adverse events were analyzed for Part B for this outcome measure.

Incudes clinically significant changes such as changes in vital signs or lab values. Relationship of AE to treatment was determined by the Investigator. Serious AEs include death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, or an important medical event that jeopardized the participant and required medical intervention to prevent the previously listed serious outcomes.

It contains 2 subscales (emotional problems and functional problem). Total score: sum of 2 subscales, ranging from 0 to 51, with higher score indicating more depression-related behaviors. |

Children were asked to choose 1 of 3 statements that most closely aligns with their feelings in past 2 weeks. It contains 6 subscales (emotional problem, negative mood/physical symptoms, negative self-esteem, functional problems, ineffectiveness, interpersonal problems). Total score: sum of all subscales scores, ranging from 0 to 56, with higher score indicating greater depression severity.CDI-2 parent: 17-item questionnaire administered to parents to assess depression-related behaviors observed in their children. |
| Primary | Change From Randomized Withdrawal Baseline (Week 28) in the Children's Depression Inventory Second Edition (CDI-2; Parent Version) Total Score at Week 30 | Week 28, Week 30 | Parents were asked to rate their child's behaviors in past 2 weeks on a 4-point Likert scale from "not at all" to "much or most of the time."

| Primary | Number of Participants Reporting Any Suicidal Ideation or Suicidal Behavior According to the Columbia Suicide Severity Rating Scale (C-SSRS) | Baseline, Weeks 2, 4, 8, 15, 28, 34, 41, 54, 55 | C-SSRS included responses for Suicidal Ideation or Suicidal Behavior in following 10 categories: 1 = Wish to be dead; 2 = Non-specific active suicidal thoughts; 3 = Active suicidal ideation with any methods (not plan) without intent to act; 4 = Active suicidal ideation with some intent to act, without specific plan; 5 = Active suicidal ideation with specific plan and intent; 6 = Preparatory acts or behavior; 7 = Aborted attempt; 8 = Interrupted attempt; 9 = Non-fatal suicide attempt; and 10 = Completed suicide. Number of participants with any suicidal ideation or suicidal behavior are reported. Any Suicidal ideation or Suicidal Behavior events reported as TEAEs along with all other reported TEAEs are included in the AE module. |
| Primary | Number of Participants Reporting Any Suicidal Ideation or Suicidal Behavior According to the Columbia Suicide Severity Rating Scale (C-SSRS) at Randomized Withdrawal Baseline Visit (Week 28) and Week 30 | Week 28, Week 30 | C-SSRS included responses for Suicidal Ideation or Suicidal Behavior in following 10 categories: 1 = Wish to be dead; 2 = Non-specific active suicidal thoughts; 3 = Active suicidal ideation with any methods (not plan) without intent to act; 4 = Active suicidal ideation with some intent to act, without specific plan; 5 = Active suicidal ideation with specific plan and intent; 6 = Preparatory acts or behavior; 7 = Aborted attempt; 8 = Interrupted attempt; 9 = Non-fatal suicide attempt; and 10 = Completed suicide.

| Secondary | Change From Baseline in the Yale Global Tic Severity Scale (YGTSS) Total Tic Score (TTS) | Baseline, Weeks 8, 15, 28, 41, 54, and 55 | YGTSS rating scale is a semi-structured clinician rating instrument that provides an evaluation of the number, frequency, intensity, complexity, and interference of motor and phonic tics. YGTSS is composed of 11 items: 5 items for motor tic severity, 5 items for vocal tic severity, and 1 item for impairment. Each item for motor tic severity and vocal is rated on a 6-point scale (0 for none to 5 to severe). MTSS is the sum of the 5 items for motor tic severity and VTSS is the sum of the 5 items for vocal tic severity. TTS is the sum of MTSS and VTSS, ranges from 0 (none/absent) to 50 (severe). Higher scores indicate greater severity/worse outcome. Baseline is defined as the last measurement on or prior to the first dose of the open-label study medication. |
| Secondary | Change From Baseline in the Tourette Syndrome-Clinical Global Impression (TS-CGI) Score | Baseline, Weeks 8, 15, 28, 41, 54, and 55 | The TS-CGI scale is a 7-point Likert scale that allows the clinician to use all available information to assess the impact of tics on the participant's quality of life. The TS-CGI is rated as follows: 1 (normal or no tics at all), 2 (borderline), 3 (mild), 4 (moderate), 5 (marked), 6 (severe), and 7 (extreme, incapacitating tics). Lower scores indicate better quality of life. Baseline is defined as the last measurement on or prior to the first dose of the open-label study medication. |
