Long-Term Safety Study of KarXT and KarX-EC for Managing Agitation in Alzheimers Disease

What this Trial Is About

This research aims to evaluate the long-term efficacy and safety of a combined formulation of xanomeline tartratetrospium chloride in an immediate release capsule KarXT and xanomeline enteric capsules KarX-EC for treating agitation in participants with Alzheimers Disease. The study focuses on individuals who have completed prior parent studies CN012-0023 or CN012-0024 and seeks to understand treatment effects over an extended period. Participants will receive specified doses of KarXT and KarX-EC on designated days as part of this single-group, non-randomized study. The treatment phase lasts up to approximately 30 weeks, during which the combined drugs are administered and monitored for safety and effectiveness related to agitation management in Alzheimers Disease. Throughout the study, participants will be monitored for treatment-emergent adverse events and other safety measures. Assessments include tracking adverse events, serious adverse events, changes in vital signs, laboratory evaluations, electrocardiograms, cognitive function tests like the Mini-mental State Examination and ADAS-Cog-13, as well as symptom severity scales. Caregiver involvement is required to provide support and facilitate study participation. The total study duration extends up to about 30 weeks with ongoing safety and efficacy evaluations.
