| Primary | Change From Baseline to 10-Week Endpoint in the Pediatric Anxiety Rating Scale (PARS) Severity Score Evaluated for Symptoms Identified on the Generalized Anxiety Subsection of the PARS Symptom Checklist | PARS severity score for GAD was assessed for all symptoms identified in the generalized anxiety section of the PARS symptom checklist. PARS severity score for GAD was derived by summing 5 of 7 severity/impairment/interference items (2, 3, 5, 6, 7); each item ranged from 0 (none) to 5 (extreme severity/impairment/interference). PARS severity scores for GAD ranged from 0 (none) to 25 (extreme severity), with a score of 15 indicating moderate illness severity. Least squares (LS) mean was calculated using a mixed-effects model repeated measures (MMRM) approach adjusted for baseline, pooled investigator, age category, visit, treatment, treatment*visit, age category*visit, and baseline*visit. | Baseline, 10 weeks | No |
| Secondary | Response Rate at Endpoint for Generalized Anxiety Disorder (GAD) Using Pediatric Anxiety Rating Scale (PARS) Severity Score for GAD | Response rate was defined as the percentage of participants having a 50% improvement from baseline to endpoint on the PARS severity score for GAD. PARS severity score for GAD was assessed for all symptoms identified in the generalized anxiety section of the PARS symptom checklist. PARS severity score for GAD was derived by summing 5 of 7 severity/impairment/interference items (2, 3, 5, 6, 7); each item ranged from 0 (none) to 5 (extreme severity/impairment/interference). PARS severity scores for GAD ranged from 0 (none) to 25 (extreme severity), with a score of 15 indicating moderate illness severity. | Baseline, 10 weeks | No |
| Secondary | Change From Baseline to 10-Week Endpoint on the Pediatric Anxiety Rating Scale (PARS) Severity Total Score Evaluated for All Symptoms Identified on the PARS Symptom Checklist Symptoms | PARS severity total score was assessed for all symptoms identified on the PARS symptom checklist. PARS severity total score was derived by summing 5 of 7 severity/impairment/interference items (2, 3, 5, 6, 7); each item ranged from 0 (none) to 5 (extreme severity/impairment/interference). PARS severity total scores ranged from 0 (none) to 25 (extreme severity), with a score of 15 indicating moderate illness severity. Least squares (LS) mean was calculated using a mixed-effects model repeated measures (MMRM) approach adjusted for treatment, pooled investigator, visit, baseline, age category, treatment*visit, baseline*visit, and age category*visit. | Baseline, 10 weeks | No |
| Secondary | Change From Baseline to 10-Week Endpoint on the Clinical Global Impression of Severity (CGI-S) Scale | The CGI-S scale evaluated the severity of illness at the time of assessment. Scores ranged from 1 (normal, not at all ill) to 7 (among the most extremely ill). Higher scores indicated a greater severity of illness. Least squares (LS) mean was calculated using a mixed-effects model repeated measures (MMRM) approach adjusted for treatment, pooled investigator, visit, baseline, age category, treatment*visit, baseline*visit, and age category*visit. | Baseline, 10 weeks | No |
| Secondary | Remission Rate at Endpoint for Generalized Anxiety Disorder (GAD) Using Clinical Global Impressions of Severity (CGI-S) Scale | Remission rate was defined as the percentage of participants having a CGI-S score =2 at endpoint. The CGI-S scale evaluated the severity of illness at the time of assessment. Scores ranged from 1 (normal, not at all ill) to 7 (among the most extremely ill). Higher scores indicated a greater severity of illness. | 10 weeks | No |
| Secondary | Change From Baseline to 10-Week Endpoint in the Children's Global Assessment Scale (CGAS) | The CGAS was a clinician-rated assessment of general functioning. CGAS raw scores ranged from 1 (greatest impairment) to 100 (superior functioning). Lower scores indicated a lower level of functioning and greater impairment. Least squares (LS) mean from an analysis of covariance (ANCOVA) was adjusted for treatment, pooled investigator, baseline, and age category. | Baseline, 10 weeks | No |
| Secondary | Percentage of Participants During the 10-Week Period With Treatment-Emergent (New or Worsening) Suicidal Ideation as Assessed by the Columbia-Suicide Severity Rating Scale (C-SSRS) | The C-SSRS captured occurrence, severity, and frequency of suicide-related thoughts and behaviors. Suicidal ideation: a "yes" answer to any 1 of 5 suicidal ideation questions: wish to be dead, and 4 different categories of active suicidal ideation. Results reported as percentage of participants with treatment-emergent (new or worsening) suicidal ideation from baseline=(number of participants with changes compared to baseline/total number of participants at risk)*100. | Baseline up to 10 weeks | Yes |
| Secondary | Percentage of Participants During the 10-Week Period With Treatment-Emergent (New or Worsening) Suicidal Behavior as Assessed by the Columbia-Suicide Severity Rating Scale (C-SSRS) | The C-SSRS captured 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. Reported as percentage of participants with treatment-emergent (new or worsening) suicidal behavior from baseline=(number of participants with changes compared to baseline/total number of participants at risk)*100. | Baseline up to 10 weeks | Yes |
| Secondary | Change From 10-Week to 28-Week Endpoint in the Pediatric Anxiety Rating Scale (PARS) Severity Score Evaluated for Symptoms Identified on the Generalized Anxiety Subsection of the PARS Symptom Checklist | PARS severity score for GAD was assessed for all symptoms identified in the generalized anxiety section of the PARS symptom checklist. PARS severity score for GAD was derived by summing 5 of 7 severity/impairment/interference items (2, 3, 5, 6, 7); each item ranged from 0 (none) to 5 (extreme severity/impairment/interference). PARS severity scores for GAD ranged from 0 (none) to 25 (extreme severity), with a score of 15 indicating moderate illness severity. Least squares (LS) mean was calculated using a mixed-effects model repeated measures (MMRM) approach adjusted for pooled investigator, visit, baseline, age category, baseline*visit, and age category*visit within reporting groups. | 10 weeks, 28 weeks | No |
| Secondary | Change From 10-Week to 28-Week Endpoint on the Pediatric Anxiety Rating Scale (PARS) Severity Total Score Evaluated for All Symptoms Identified on the PARS Symptom Checklist Symptoms | PARS severity total score was assessed for all symptoms identified on the PARS symptom checklist. PARS severity total score was derived by summing 5 of 7 severity/impairment/interference items (2, 3, 5, 6, 7); each item ranged from 0 (none) to 5 (extreme severity/impairment/interference).
