Study Background
This study is testing how effective KarXT is for treating manic episodes in people with Bipolar I Disorder.
This study is testing a new investigational medication called KarXT to see how effective it is in treating manic episodes in people with Bipolar I Disorder. It is a Phase 3, randomized, double-blind, placebo-controlled clinical trial, meaning that participants will be randomly assigned to receive either the study drug or a placebo, and neither the participants nor the study staff will know which treatment is being given. Before beginning the study, eligible participants will need to stop taking their current antipsychotic medications. All participants will stay at the inpatient facility for the duration of the study, which may last up to 36 days, including a follow-up outpatient visit after discharge.
During the inpatient stay, participants will complete 10 study visits involving physical exams, physician questionnaires, EKGs, and blood draws for lab work or study-related testing. The final follow-up visit will be done as an outpatient to monitor safety after treatment ends. The main goal of the study is to determine whether KarXT is an effective treatment option for managing manic episodes in individuals diagnosed with Bipolar I Disorder.
