Phase 3 Study of KarXT KarX-EC to Treat Agitation in Adults with Alzheimers Disease

What this Trial Is About

Researchers are evaluating the safety and effectiveness of KarXT combined with KarX-EC in adults aged 55 to 90 who have agitation related to Alzheimers Disease. This Phase 3, randomized, double-blind, placebo-controlled study aims to address agitation symptoms in this population by comparing the investigational drugs with a placebo. The study is sponsored by Bristol-Myers Squibb and uses established diagnostic criteria for Alzheimers Disease. Participants will receive either the combination of XanomelineTrospium Chloride capsules KarXT KarX-EC or a placebo with specified doses on designated days. The study includes a parallel group design and treatment lasts for 14 weeks. The main focus is to assess changes in agitation using the Cohen-Mansfield Agitation Inventory-International Psychogeriatric Association CMAI-IPA total score. During the study, participants will undergo regular assessments including cognitive and behavioral evaluations, safety monitoring through vital signs, laboratory tests, electrocardiograms, and rating scales for movement disorders and suicidal ideation. Caregivers will be involved to help monitor participant status and medication compliance. The primary outcome is measured at Week 14, with safety follow-up extending to Week 18. Participants are expected to be engaged throughout the treatment period and follow-up assessments.
