Brief summary
The purpose of this study is to determine if quetiapine fumarate extended-release (quetiapine XR or SEROQUEL® XR) 150 to 300 mg/day taken by itself is effective and safe in treating children or adolescents aged 10 to 17 with bipolar depression and if so, how it compares with placebo (a non-active tablet, like a sugar pill, that looks like quetiapine).
Interventions
Oral treatment with 150 up to 300 mg/day once daily in the evening
Oral treatment once daily in the evening

Outcome results
Change in the Children Depression Rating Scale, Revised (CDRS-R) Total Score From Baseline to Final Assessment (Day 57)
Severity of depression in children and adolescents was calculated based on the 17-item CDRS-R scale (3 items scored from 1-5 and 14 items scored from 1-7, with higher scores indicating more severe depression). The 17 item scores are summed to give the total score (total score range 17-113).
Time frame: Will be scored at all visits. the analysis is the change from baseline to the final assessment at day 57

| Quetiapine XR | Change in the Children Depression Rating Scale, Revised (CDRS-R) Total Score From Baseline to Final Assessment (Day 57) | -29.6 Scores on a scale | Standard Error 1.65 |
| Placebo | Change in the Children Depression Rating Scale, Revised (CDRS-R) Total Score From Baseline to Final Assessment (Day 57) | -27.3 Scores on a scale | Standard Error 1.6 |
CGI-BP-C Score at Final Assessment (Day 57)

The Proportion of Patients at Final Assessment (Day 57) With Improvement of Overall Bipolar Illness
The proportion of patients with improvement of overall bipolar illness at Day 57 was calculated. Improvement defined as a CGI-BP-C of Much or Very much improved in overall bipolar illness assessment.
Time frame: Day 57
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Quetiapine XR | The Proportion of Patients at Final Assessment (Day 57) With Improvement of Overall Bipolar Illness | 0.522 Proportions |
