Researchers are evaluating the safety and effectiveness of KarXT combined with KarX-EC in adults aged 55 to 90 who have agitation related to Alzheimer's Disease. This phase 3 study aims to better understand how these treatments impact agitation symptoms in this population by comparing them to a placebo group. Participants must have a confirmed Alzheimer's diagnosis and meet specific criteria for agitation severity to join the study. Participants will receive either the Xanomeline/Trospium Chloride Capsule, Xanomeline Enteric Capsule, or a placebo, each given at specified doses on designated days. The study is randomized, double-blind, and placebo-controlled to ensure reliable comparison of treatment effects. The treatment period lasts through Week 14, during which dosing schedules are closely followed. Throughout the study, participants will be regularly assessed using the Cohen-Mansfield Agitation Inventory-International Psychogeriatric Association (CMAI-IPA) to measure changes in agitation levels from baseline to Week 14. Caregivers will provide reports on participant status and help ensure medication compliance. Safety and symptom changes will be carefully monitored to evaluate the treatments' effects during this period.

This trial focuses on people aged 55 to 90 who have agitation related to Alzheimer's Disease and previously finished one of two earlier studies. It aims to assess the long-term safety and effectiveness of a combination treatment using xanomeline tartrate/trospium chloride immediate release capsules (KarXT) and xanomeline enteric capsules (KarX-EC) in these participants. The study is a Phase 3 open-label extension, meaning all participants receive the treatment while researchers observe effects over time. Participants receive specified doses of KarXT and KarX-EC on set days as part of the treatment regimen. The study follows those who completed the earlier parent studies CN012-0023 or CN012-0024, continuing to monitor their response to the combined medication over an extended period. Throughout the study, researchers evaluate the number of participants who experience any treatment-emergent adverse events up to about 30 weeks. Caregiver involvement is required, with at least one caregiver having regular contact of about 10 hours per week or more. Safety and tolerability are closely monitored to understand the long-term impact of the treatment in managing agitation associated with Alzheimer's Disease.

Researchers are evaluating ACP-204, a drug that blocks a specific serotonin receptor, in adults aged 55 to 95 with Alzheimer's Disease Psychosis (ADP). The study is designed as a master protocol with three independent, multicenter, randomized, double-blind, placebo-controlled trials. The trials include Phase 2 and Phase 3 studies to assess the drug's effectiveness and safety in treating psychotic symptoms associated with ADP. The research involves three substudies. Substudy 1 (Phase 2) tests two doses of ACP-204, 30 mg and 60 mg, against a placebo to evaluate dose response. Substudies 2A and 2B (both Phase 3) will independently confirm the effects of either both doses or a single dose from Part 1 compared to placebo. Each substudy includes a screening period of up to 49 days, a six-week double-blind treatment phase, and a 30-day safety follow-up for those not continuing into an open-label extension. Vital status follow-up is conducted for participants who end the study early. Participants will receive regular assessments, including evaluations of psychotic symptoms using the Scale for the Assessment of Positive Symptoms-Hallucinations and Delusions subscales from baseline to Week 6. Other study involvement includes brain imaging scans and biomarker tests to confirm Alzheimer's disease diagnosis, cognitive testing, and monitoring of safety and vital status throughout the study periods. Stable living arrangements and support from a caregiver are required to complete all study visits.
