Primary Outcome Measures:
  • Change From Baseline in Young Mania Rating Scale (YMRS) Score at Week 4 [ Time Frame: Baseline, Week 4 ] [ Designated as safety issue: No ]
    YMRS: an 11-item scale that measured the severity of manic episodes. Four items were rated on a scale from 0 (symptom absent) to 8 (symptom extremely severe). The remaining items were rated on a scale from 0 (symptom absent) to 4 (symptom extremely severe). YMRS total score ranged from 0 to 60, higher score indicated higher severity of mania.


Secondary Outcome Measures:
  • Change From Baseline in Young Mania Rating Scale (YMRS) Score at Week 1, 2 and 3 [ Time Frame: Baseline, Week 1, 2, 3 ] [ Designated as safety issue: No ]
    YMRS: an 11-item scale that measured the severity of manic episodes. Four items were rated on a scale from 0 (symptom absent) to 8 (symptom extremely severe). The remaining items were rated on a scale from 0 (symptom absent) to 4 (symptom extremely severe). YMRS total score ranged from 0 to 60, higher score indicated higher severity of mania.

  • Change From Baseline in Clinical Global Impression - Severity (CGI-S) Score at Week 1, 2, 3 and 4 [ Time Frame: Baseline, Week 1, 2, 3, 4 ] [ Designated as safety issue: No ]
    CGI-S: 7-point clinician rated scale to assess severity of participant's current illness state; range: 1 (normal - not ill at all) to 7 (among the most extremely ill).

  • Clinical Global Impression - Improvement (CGI-I) Score [ Time Frame: Week 1, 2, 3, 4 ] [ Designated as safety issue: No ]
    CGI-I: 7-point clinician rated scale ranging from 1 (very much improved) to 7 (very much worse). Improvement is defined as a score of 1 (very much improved), 2 (much improved), or 3 (minimally improved) on the scale.
