Trial Outcomes & Findings for Pediatric Bipolar Depression (NCT NCT00811473)

NCT ID: NCT00811473

Last Updated: 2014-07-15

Results Overview

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).

Participant Flow

This multicenter study was conducted between 27 January 2009 and 1 November 2010, which included the recall visit. The recall visit occurred from 5 June 2010 till 1 November 2010.

The study had an up to 35-day enrollment period, 8-week double-blind treatment period with 1 of 2 treatment regimens (quetiapine XR 150 to 300 mg/day or placebo), 1-week safety follow-up period, 2- to 4-week safety follow-up period for patients with BP \>95th percentile at completion/discontinuation.

SECONDARY outcome

Timeframe: 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).

SECONDARY outcome

Timeframe: 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.

SECONDARY outcome

Timeframe: 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.
