Outcomes

Primary Outcomes

Change From Baseline in Children's Depression Rating Scale-Revised (CDRS-R) Total Score at Week 10 Endpoint

CDRS-R Total score measure the presence and severity of depression in children. The scale consists of 17 items scored on a 1-to-5- or 1-to-7-point scale. A rating of 1 indicates normal functioning. Total scores range from 17 to 113. In general, scores below 20 indicate an absence of depression, scores of 20 to 30 indicate borderline depression, and scores of 40 to 60 indicate moderate depression. Least Square (LS) means are adjusted for baseline, pooled investigator, age category, visit, treatment, treatment\*visit, age category\*visit and baseline\*visit.

Time frame: Baseline, Week 10

Secondary Outcomes

Change From Week 10 in Children's Depression Rating Scale-Revised (CDRS-R) Total Score at Week 36 Endpoint

CDRS-R Total score measure the presence and severity of depression in children. The scale consists of 17 items scored on a 1-to-5- or 1-to-7-point scale. A rating of 1 indicates normal functioning. Total scores range from 17 to 113. In general, scores below 20 indicate an absence of depression, scores of 20 to 30 indicate borderline depression, and scores of 40 to 60 indicate moderate depression. LS means are adjusted for baseline, pooled investigator, age category, visit, age category\*visit and baseline\*visit.

Time frame: Week 10, Week 36

Change From Baseline in Children's Depression Rating Scale-Revised (CDRS-R) Subscale Score at Week 10 Endpoint

CDRS-R Subscale scores include Mood (Sum of items 8, 11, 14, 15), Somatic (Sum of items 4-7, 16, 17), Subjective (Sum of items 9, 10, 12, 13) and Behavior (Sum of items 1-3). Mood and Subjective subscale scores range from 4 to 28; Somatic subscale scores range from 6 to 36; Behavior subscale scores range from 3 to 21. Higher score indicates greater severity of disease. LS means are adjusted for baseline, pooled investigator, age category, visit, treatment, treatment\*visit, age category\*visit and baseline\*visit.

Change From Baseline in Clinical Global Impressions of Severity (CGI-Severity) Scale at Week 10 Endpoint

CGI-Severity evaluates the severity of illness at the time of assessment. The score ranges from 1 (normal, not at all ill) to 7 (among the most extremely ill patients). LS means are adjusted for baseline, pooled investigator, age category, visit, treatment, treatment\*visit, age category\*visit and baseline\*visit.

Time frame: Week 10, Week 36

Number of Participants With Suicidal Ideation or Suicidal Behavior Baseline Through Week 10

Columbia Suicide Rating Scale (C-SSRS) captures occurrence, severity, and frequency of suicide-related thoughts and behaviors. Suicidal behavior: a "yes" answer to any of 5 suicidal behavior questions: preparatory acts or behavior, aborted attempt, interrupted attempt, actual attempt, and completed suicide. Suicidal ideation: a "yes" answer to any one of 5 suicidal ideation questions: wish to be dead, and 4 different categories of active suicidal ideation. Treatment Emergent Suicidal Ideation is worsening or new occurrence of events during treatment compared to lead-in baseline (Week -1 - 0).

Time frame: Baseline through Week 10

Number of Participants With Potentially Clinically Significant Hepatic Laboratory Results Any Time Baseline Through Week 10

Total number of participants with any abnormal post-baseline value, based on all values at scheduled and unscheduled visits. Potentially clinically significant hepatic laboratory results at any time are defined as alanine transaminase (ALT) ≥3 x upper limit of normal (ULN), ALT ≥5 x ULN and ALT ≥10 x ULN, as well as ALT ≥3 x ULN and Total Bilirubin ≥2 x ULN.
