Primary Outcome Measures
NameTimeMethod
Change from baseline in Young Mania Rating Scale (YMRS) scoreAt week 3

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.

Secondary Outcome Measures
NameTimeMethod
Change from baseline in Clinical Global Impressions-Bipolar (CGI-BP)At week 3

The CGI-BP is designed to assess the severity, improvement, and efficacy of treatment in individuals with bipolar disorder. Only section I, illness severity, will be used, which includes three components: mania, depression, and overall bipolar illness. The ratings are on a 7-point scale (1 = normal, not ill; 2 = minimally ill; 3 = mildly ill; 4 = moderately ill; 5 = markedly ill; 6 = severely ill; 7 = very severely ill)

Occurrence of response based on a ≥ 50% decrease from baseline in YMRS scoreAt week 3
Occurrence of response based on CGI-BP change from baseline ≥ 1At week 3
