| Measure | Time frame | Description |
|---|---|---|
| Time to First Relapse of Any Mood Episode During the Double-Blind Treatment Period | From 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. |

Outcome results
Time to First Relapse of Any Mood Episode During the Double-Blind Treatment Period
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.
Time frame: From Week 16 to Week 55
Population: Double-Blind Intent-to-Treat Population: All participants who took at least 1 dose of DB IP and had at least 1 post-randomization assessment of the YMRS, MADRS or CGI-S scores or relapsed during the 39-week DBTP of the study.
