Inclusion criteria
* Participants must have a primary diagnosis of Bipolar-I disorder established by a comprehensive psychiatric evaluation. * Participants must be experiencing an acute episode or relapse of mania or mania with mixed features (≤ 3 weeks). * Participants must require hospitalization for the acute exacerbation or relapse of mania. * Participants must have all psychotropic medications washed out in no more than 14 days prior to the first dose of the study drug. * Participants must have a Young Mania Rating Scale (YMRS) score of ≥ 20 at Screening and at Baseline. * Participants must have a Clinical Global Impressions-Bipolar (CGI-BP) ≥ 4 at Screening and at Baseline.
Exclusion criteria
* Participants must not have any primary Diagnostic and Statistical Manual of Mental Disorders (5th Edition, Text Revision) (DSM-5-TR) disorder, other than BP-I with mania or mania with mixed features within 12 months before screening, including BP-I with depression (for previous 3 months only), BP-II disorder, borderline personality disorder, major depressive disorder, and primary psychotic disorder, with the exception of mild anxiety disorders. * Participants must not have a primary diagnosis of BP-I with rapid cycling (≥ 4 distinct mood episodes in one year). * Participants must not have a DSM-5-TR diagnosis of moderate to severe substance use disorder (except tobacco use disorder) within the 12 months before screening, or current use as determined by urine toxicology screen or alcohol test. * Participants must not be at risk for suicidal behavior at screening or the baseline visit as determined by the Investigator's clinical assessment and the Columbia-Suicide Severity Rating Scale (C-SSRS). * Participants must not have cirrhosis, liver cancer, clinically significant liver disease based on the liver function test results. * Other protocol-defined Inclusion/
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in Young Mania Rating Scale (YMRS) score | At 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
| Measure | Time frame | Description |
|---|---|---|
| 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 ≥ 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 | At week 3 | — |
