Researchers are evaluating the safety and effectiveness of KarXT in preventing relapse of psychosis symptoms in people aged 55 to 90 years who have psychosis associated with Alzheimer's Disease. This Phase 3 study is randomized, double-blind, placebo-controlled, and conducted at multiple outpatient centers. The main goal is to compare relapse prevention between KarXT treatment and placebo over 38 weeks, while also assessing time to discontinuation, safety, and tolerability. Participants receive either KarXT in varying doses (ranging from 20 mg/2 mg to 66.7 mg/6.67 mg taken three times daily) or placebo capsules. The study lasts 38 weeks, during which participants remain on assigned treatment in an outpatient setting. The randomized, double-blind design ensures neither participants nor researchers know who receives KarXT or placebo during the study. Throughout the study, participants will visit the clinic regularly for assessments of their psychosis symptoms, safety checks, and overall health. Researchers will track the time to relapse of psychosis symptoms as the primary outcome. They will also monitor safety and tolerability through clinical examinations and other evaluations. The total duration of participation is 38 weeks from randomization to the end of the study period.

Researchers are evaluating the long-term safety and tolerability of adjunctive KarXT, a combination of xanomeline and trospium chloride, in adults aged 18 to 65 with schizophrenia who did not have sufficient symptom control with their current antipsychotic medications. This Phase 3, open-label extension study involves participants who previously completed the treatment period of the ARISE study (KAR-012). The goal is to monitor how well patients tolerate KarXT over an extended period while assessing related safety concerns. Participants receive fixed doses of KarXT capsules twice daily, with doses ranging from 50 mg/20 mg up to 125 mg/30 mg. The study lasts for 52 weeks as an outpatient program. This open-label extension allows researchers to observe the effects and safety of KarXT when added to stable antipsychotic treatment under real-world conditions. During the study, researchers closely monitor participants for any treatment-emergent adverse events from the initial dose through a safety follow-up visit at 54 weeks or early termination. Participants will undergo regular assessments, including clinical evaluations and reports from reliable caregivers who assist with study activities. The study ensures participants maintain stable living situations and continue their background antipsychotic medications throughout the study period.

The trial investigates the long-term safety and tolerability of KarXT in people with psychosis associated with Alzheimer's Disease. This Phase 3 global, multicenter, open-label extension study lasts 52 weeks and enrolls participants who have completed earlier related studies (CN012-0026, CN012-0027, or CN012-0056). The purpose is to monitor how well patients tolerate KarXT over an extended period and to collect safety data. Participants receive KarXT in varying doses taken three times daily, ranging from 20/2 mg up to 66.7/6.67 mg per dose, corresponding to total daily doses between 60/6 mg and 200/20 mg. This treatment is provided throughout the 52-week open-label extension. The study includes only those who completed the previous related studies and continues to assess their response to KarXT over this longer timeframe. During the study, participants are closely monitored for treatment-emergent adverse events from the first dose through 14 days after the final dose, which may be up to 54 weeks. Regular assessments ensure safety and tolerability, and caregivers are involved to support participants. The study also evaluates participants' ability to continue living in their current setting and requires consent from the participant or their legal representative. Overall, the study tracks long-term safety outcomes in this specific patient group.
