Researchers are evaluating the safety and effectiveness of KarXT combined with KarX-EC in adults aged 55 to 90 who experience agitation related to Alzheimers Disease. This Phase 3 study aims to understand how these medications impact agitation symptoms in this population, using recognized criteria to confirm Alzheimers diagnosis and agitation severity. Participants will be randomly assigned to receive either the combination of KarXT and KarX-EC or a placebo. Dosing is specified for certain days, and the study includes a 14-week treatment period during which agitation and other symptoms will be closely monitored. The study design includes a quadruple-blind method to reduce bias. During the study, participants and their caregivers will attend regular visits where the researchers will assess changes in agitation using tools like the Cohen-Mansfield Agitation Inventory and Clinical Global Impressions-Severity scale. Safety will also be carefully monitored through various assessments including vital signs, lab tests, ECGs, and movement scales. Participant involvement extends up to 18 weeks to capture any adverse events and treatment effects.

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.

Researchers are evaluating ACP-204, a drug targeting serotonin receptor subtype 2A, in adults aged 55 to 95 years with psychosis related to Alzheimers disease. This master protocol includes three independent, randomized, double-blind, placebo-controlled studies aimed at assessing the drugs efficacy and dose response. Substudy 1 is a Phase 2 trial comparing two doses of ACP-204 30 mg and 60 mg to placebo, followed by two Phase 3 confirmatory studies Substudies 2A and 2B that will independently evaluate the doses or a selected dose against placebo. Participants will undergo a screening period lasting up to 49 days before starting a six-week double-blind treatment phase where they will receive daily doses of ACP-204 or placebo, taken once a day at about the same time with or without food. After treatment, there is a 30-day safety follow-up for those not entering an open-label extension, and vital status follow-up for those who end the study early. Each substudy is analyzed separately to assess the drugs impact. During the trial, participants are closely monitored with assessments including the Scale for the Assessment of Positive Symptoms-Hallucinations and Delusions SAPS-HD from baseline to week 6. Other evaluations include clinical global impression scales and safety monitoring. Participants must have a study partner or caregiver to assist with visits and adherence. The study is designed to track changes in psychosis symptoms and overall safety through the treatment and follow-up periods.
