What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Children's Depression Rating Scale - Revised (CDRS-R) Total Score | The Children's Depression Rating Scale-Revised (CDRS-R) total score ranges from 17 (minimal or no symptoms of depression) to 133 (indicative of depression) is a semi-structured, clinician-rated instrument designed for use with children and adolescents between the ages of 6 to 17 years of age and their caregivers. The CDRS-R evaluates the presence and severity of symptoms commonly associated with depression in childhood. | From Baseline to week 8 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Clinical Global Impressions-Severity (CGI-S) Score | The Clinical Global Impressions-Severity (CGI-S) is a clinician-rated instrument used to rate the severity of the patient's current state of mental illness compared with the clinician's total experience with patients with major depressive disorder (MDD). The severity of the patient's MDD was rated on a scale from 1 to 7, with 1 indicating a normal state and 7 indicating a patient who is among the most extremely ill patients. | From Baseline to Week 8 |
