Long-term Safety Study of KarXT for Mania or Mixed Mania in Bipolar-I Disorder Adults

What this Trial Is About

Researchers are conducting a phase 3, open-label extension study to assess the long-term safety and tolerability of KarXT for treating mania or mania with mixed features in adults with Bipolar-I disorder. The study focuses on evaluating how participants respond to KarXT over an extended period, emphasizing safety measurements such as adverse events and symptom changes. Participants will receive KarXT at specified doses over a treatment period lasting up to 54 weeks. This study includes participants previously involved in related placebo-controlled studies as well as new participants diagnosed with Bipolar-I disorder with manic symptoms. The treatment may be given alongside standard therapeutic doses of lithium, valproate, or lamotrigine as applicable. Throughout the study, participants will undergo regular assessments including monitoring of treatment emergent adverse events, serious adverse events, and psychiatric symptom scales like the Columbia-Suicide Severity Rating Scale, Young Mania Rating Scale, and others. Safety and tolerability will be closely tracked, with evaluations occurring up to week 54. The entire participation may last until the study end date in June 2028, ensuring comprehensive long-term follow-up.
