Rating ranges from 1 (normal, not at all ill) to 7 (among the most severely ill subjects); higher score = more affected. Change calculated as mean of (value of CGI-S score at observation minus baseline value). |
| Clinical Global Impression - Improvement (CGI-I) Scale Scores | Week 1, Week 2, Week 3 | CGI-I is a single-item clinician rated scale used to assess global improvement in the subject's clinical state (bipolar mania) in response to study treatment and as compared to their status at pre-treatment baseline. Scores range from 1 (very much improved) to 4 (no change) to 7 (very much worse); higher score = more affected. |

| Change From Baseline in Longitudinal Interval Follow-up Evaluation Range of Impaired Functioning (LIFE-RIFT) Score | Baseline, Week 3 | LIFE-RIFT measures severity of illness-related impairment in 4 domains: work, interpersonal relations, recreation, and global satisfaction; has a total score and individual domain scores. Domain scores range from 1 to 5 (scores ≥ 2 reflect impaired functioning).
