Last verified: July 2014
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).

Primary Outcome Measures:
  • Change in the Children Depression Rating Scale, Revised (CDRS-R) Total Score From Baseline to Final Assessment (Day 57) [ Time Frame: Will be scored at all visits. the analysis is the change from baseline to the final assessment at 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).

Secondary Outcome Measures:
  • Number of Patients Reaching Remission Where Remission is Defined as CDRS-R Total Score ≤28 at Final Assessment (Day 57). [ Time Frame: Days 8 to 57 ]
    The number of patients with remission from Days 8 to 57 was calculated. The CDRS-R is a 17-item scale with 3 items scored from 1-5 and 14 items scored from 1-7, where higher scores indicating more severe depression. The 17 item scores are summed to give the total score (total score range 17-113).

  • The Number of Patients With the Response, Where Response is Defined as ≥50% Reduction From Baseline to Final Assessment (Day 57) in CDRS-R Total Score [ Time Frame: Days 8 to 57 ]
    The number of patients reaching response from Days 8 to 57 was calculated. The CDRS-R is a 17-item scale with 3 items scored from 1-5 and 14 items scored from 1-7, where higher scores indicating more severe depression. The 17 item scores are summed to give the total score (total score range 17-113).

  • Change From Baseline to Final Assessment (Day 57) in the CGI-BP-S [ Time Frame: Change from Baseline to Day 57 ]
    The CGI-BP-S scale rates the severity of the patient's illness at the time of assessment and is scored from 1 to 7 (1=normal, not ill to 7=very severely ill). Higher CGI-BP-S scores indicate greater illness severity.

  • CGI-BP-C Score at Final Assessment (Day 57) [ Time Frame: Change from Baseline to day 57 ]
    The CGI-BP-C scale rates how much the patient's illness has improved or worsened compared to the phase immediately preceding treatment and is scored on a scale from 1 to 8 (1=very much improved to 7=very much worse; 8=not applicable). CGI-BP-C scores >4 indicate worsening, while scores <4 indicate improvement.

  • The Proportion of Patients at Final Assessment (Day 57) With Improvement of Overall Bipolar Illness [ Time Frame: Day 57 ]
    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.
