Change From Baseline in the Young Mania Rating Scale (YMRS) Total Score at Week 3

The YMRS is an 11-item scale that assesses manic symptoms based on the participant's perception of his or her condition over the previous 48 hours, as well as the physician's clinical observations during the interview. The 11-items are elevated mood, increased motor activity-energy, sexual interest, sleep, irritability, rate and amount of speech, language-thought disorder, content, disruptive-aggressive behavior, appearance, and insight. The severity of the abnormality for 7-items are rated on a five-point scale (0-4) and 4-items on a nine-point scale (0-8). The individual scores are summed for a total possible score of 0 (best) to 60 (worst). A negative change from Baseline indicates improvement. Analyses are based on an Analysis of Covariance (ANCOVA) model for change from Baseline with treatment group and study center as factors and Baseline value as covariate.

Change From Baseline in Clinical Global Impression-Severity (CGI-S) Total Score at Week 3

The CGI-S measures the investigator's assessment of overall severity of the participant's illness compared with the severity of illness in other patients the physician has observed using a 7-point scale (1=Normal, not ill at all to 7=Among the most extremely ill participants). A negative change from Baseline indicates improvement. Analyses are based on ANCOVA model for change from Baseline with treatment group and study center as factors and Baseline CGI-S score as covariate.
