Summary

This study tests whether the drug KarXT can reduce symptoms of mania in people with Bipolar I disorder who are currently hospitalized for a manic episode. About 274 participants will receive either KarXT or a placebo for 3 weeks while staying in the hospital. The main goal is to see if KarXT improves manic symptoms better than a placebo.
