Evaluating Safety and Effectiveness of Oral Icalcaprant for Depression in Adults with Bipolar I or II Disorder

What this Trial Is About

This research aims to evaluate the safety and effectiveness of Icalcaprant in adults diagnosed with bipolar I or II disorder, specifically focusing on depressive episodes. Bipolar disorder is a chronic mood condition affecting a significant portion of the adult and pediatric populations in the United States. The study targets approximately 195 adult participants across about 35 sites in the U.S., aiming to understand how Icalcaprant impacts disease activity and adverse events. Participants are randomly assigned to one of three groups two groups receive different doses of oral Icalcaprant once daily for 6 weeks, and one group receives a matching placebo daily for the same period. After the treatment phase, all participants enter a 4-week safety follow-up period. The study uses a parallel design with quadruple masking to compare the effects of the investigational drug versus placebo. During the study, participants will attend regular visits at hospitals or clinics where they undergo medical assessments, blood tests, and complete questionnaires to monitor side effects and treatment effects. Researchers will measure changes from baseline to week 6 in depression severity using the Montgomery-sberg Depression Rating Scale and the Clinician Global Impression of Severity for bipolar disorder. Safety will be monitored up to approximately 10 weeks, ensuring participant well-being throughout the trial.
