Pediatric Bipolar Depression

An 8-week, Multicenter, Double-blind, Randomized, Parallel-group, Placebo-controlled Study of the Efficacy and Safety of Quetiapine Fumarate (SEROQUEL) Extended-Release in Children and Adolescent Subjects With Bipolar Depression

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).
