Primary Outcome Measures
NameTimeMethod
Time to First Relapse of Any Mood Episode During the Double-Blind Treatment PeriodFrom Week 16 to Week 55

Relapse was defined as the occurrence of any 1 of the following:

* Young Mania Rating Score (YMRS) total score ≥ 17 (range 0-60; higher score indicates a worse outcome);

* Montgomery Asberg Depression Rating Scale; (MADRS) total score ≥ 20 (range 0-60; higher score indicates more depressive symptoms);

* Clinical Global Impression-Improvement scale (CGI-S) ≥ 4 (range from 1 \[normal, not at all ill\] to 7 \[extremely ill\]);

* Initiation of additional psychiatric medication;

* Psychiatric hospitalization;

* Exacerbation of illness as judged by clinical impression of the Investigator.

Time to first relapse (days) was calculated as the date of the first relapse - the date of randomization + 1. Participants who did not meet the relapse criteria were considered censored at the time of completion or discontinuation from the Double-Blind Treatment Period (DBTP) of the study. Percentiles (95% Confidence Intervals \[CI\]) are based on Kaplan-Meier estimates.
