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.

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 conducting a Phase 3, randomized, double-blind, placebo-controlled study to evaluate the safety and effectiveness of KarXT in men and women aged 55 to 90 years who have mild to severe Alzheimer's Disease with moderate to severe psychosis related to the condition. The main goal is to compare KarXT against a placebo by measuring changes in hallucinations and delusions using the Neuropsychiatric Inventory-Clinician (NPI-C) score. Participants will receive different doses of KarXT ranging from 20/2 mg to 66.7/6.67 mg daily or placebo capsules. The study is designed to compare the effects of KarXT with placebo in a parallel group format, maintaining the double-blind setup to ensure unbiased results. During the study, participants will be assessed at the start and end of treatment (up to 14 weeks) to evaluate changes in psychotic symptoms. They will undergo clinical scales such as the NPI-C and the Clinical Global Impression-Severity (CGI-S) scale. The study also requires imaging scans like MRI or CT to rule out other brain diseases. A study partner who has regular contact with the participant will be involved to support adherence and observation. Safety and efficacy will be monitored throughout the treatment period.

Researchers are evaluating the safety and effectiveness of KarXT combined with KarX-EC as a treatment for psychosis linked to Alzheimer's disease. This Phase 3 clinical trial focuses on people aged 55 to 90 years diagnosed with Alzheimer's disease and experiencing psychotic symptoms, such as hallucinations and delusions. The study aims to understand how this treatment affects these neuropsychiatric symptoms over approximately 14 weeks. Participants will receive either KarXT plus KarX-EC or a matching placebo at specified doses on designated days. The study is double-blind and placebo-controlled, meaning neither the participants nor the researchers know who receives the active treatment or placebo during the trial. This parallel group design helps compare the treatment's impact against no active drug. During the study, participants will be monitored for changes in hallucinations and delusions using the Neuropsychiatric Inventory-Clinician scale up to about week 14. They will also undergo brain imaging review from recent MRI or CT scans to confirm eligibility and rule out other causes of dementia. Safety and efficacy will be carefully assessed throughout the trial period, ensuring close observation of any side effects or improvements.

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 developing a database to study digital and blood-based biomarkers and their relationship to tau and amyloid PET brain imaging in older adults who are cognitively normal, have mild cognitive impairment, or mild-to-moderate Alzheimer's disease dementia. The goal is to understand how these biomarkers relate to brain pathology seen in PET scans. This is a 120-day cross-sectional study focused on collecting various types of biological and imaging data to explore these connections. Participants will have blood samples taken to analyze markers and genes, alongside PET scans using either Flortaucipir, an FDA-approved tracer, or MK6240, an investigational tracer, to detect tau protein in the brain. The study also includes retinal, digital, and MRI brain imaging as part of the biomarker database. Some biological samples will be stored for future research. These procedures aim to evaluate the relationships between digital and blood-based markers with brain amyloid and tau pathology. During the study, participants will undergo brain scans, blood draws, and cognitive testing, including the Mini-Mental State Exam. Researchers will monitor biomarkers and PET imaging results over an average of three years. Participants must have a study partner who regularly interacts with them to provide additional information. The study will also collect genetic data and assess cognitive and functional abilities. Safety and data collection procedures will be followed throughout the study duration.

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.
