Outcome Measures

Primary Outcomes (1)

  • Change from baseline in Young Mania Rating Scale (YMRS) score

    The YMRS comprised of 11 items that assess the severity of manic symptoms. All items are given a severity rating, with 4 items graded from 0 to 8 (irritability, speech, thought content, and disruptive/aggressive behavior), and the remaining 7 items are graded from 0 to 4 points. The highest score obtainable on the YMRS is 60 and the higher the number the greater the number of symptoms and/or the greater their severity.

    At week 3

Secondary Outcomes (3)

  • Change from baseline in Clinical Global Impressions-Bipolar (CGI-BP)

    At week 3

  • Occurrence of response based on ≥ 50% decrease from baseline in YMRS score or total score

    At week 3

  • Occurrence of response based on change from baseline ≥ 1 in CGI-BP
