- Moderate to severe hallucinations, defined as NPI-C: Hallucinations domain score of ≥ 2 on 2 of the 7 items
- MMSE score of 8 to 22, inclusive, at Screening.
Who cannot join
- Psychotic symptoms that are primarily attributable to a condition other than the AD causing the dementia.
- History of major depressive episode with psychotic features during the 12 months prior to Screening.
- History of bipolar disorder, schizophrenia, or schizoaffective disorder.

About this study
Official title: A Phase 3, Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study to Evaluate the Safety and Efficacy of KarXT for the Treatment of Psychosis Associated With Alzheimer's Disease
This is a Phase 3, randomized, double-blind, placebo-controlled, parallel group study to evaluate the safety and efficacy of KarXT in male and female subjects who are aged 55 to 90 years and have mild to severe Alzheimer's Disease (AD) with moderate to severe psychosis related to AD.
The primary objective of the study is to evaluate the efficacy of KarXT compared with placebo in the treatment of subjects with psychosis associated with AD as measured by the Neuropsychiatric Inventory-Clinician (NPI-C): Hallucinations and Delusions (H+D) score.
- Being tested
- KarXT, Placebo
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
KarXTDrug
KarXT 20/2 mg (total daily dose [TDD] 60/6 mg) KarXT 30/3 mg (TDD 90/9 mg) KarXT 40/4 mg (TDD 120/12 mg) KarXT 50/5 mg (TDD 150/15 mg) KarXT 66.7/6.67 mg (TDD 200/20 mg)
PlaceboDrug
Placebo capsules
| Study group | Role | What they receive |
|---|---|---|
| KarXT | Experimental | Xanomeline and Trospium Chloride Capsules Receives: Drug: KarXT |
| Placebo | Placebo comparator | Placebo capsules Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change from Baseline to End of Treatment in the Neuropsychiatric Inventory-Clinician: Hallucinations and Delusions (NPI-C: H+D) score
Neuropsychiatric Inventory-Clinician: Hallucinations and Delusions scale includes 2 domains from the NPI-C scale, namely, hallucinations and delusions. These 2 domains include the following number of items to be rated by the clinician: Hallucinations, 7 items (maximum score = 21) and Delusions, 8 items (maximum score = 24). The maximum score for the NPI-C: H+D scale is 45. Higher scores on this scale indicate worse outcomes.
Measured: Baseline and end of Treatment (up to 14 Weeks)
Secondary outcomes (5)
Change from Baseline to End of Treatment in the Clinical Global Impressions-Severity (CGI-S) scale
Clinical Global Impressions-Severity (CGI-S) requires the assessor to consider aspects of the psychosis (hallucinations and delusions) prior to providing a global assessment of severity. Higher scores on this scale indicate worse outcomes.
Measured: Baseline and end of Treatment (up to 14 Weeks)
Change From Baseline to end of Treatment in NPI-C Core score: Hallucinations, Delusions, Agitation, and Aggression Domains
Measured: Baseline and end of Treatment (up to 14 Weeks)
Change From Baseline to end of Treatment in NPI-C: Agitation score
Measured: Baseline and end of Treatment (up to 14 Weeks)
Change From Baseline to end of Treatment in NPI-C Core score: Caregiver Distress scale (Hallucinations, Delusions, Agitation, and Aggression domains)
Measured: Baseline and end of Treatment (up to 14 Weeks)
Responder Rate
Responder rate is defined as NPI-C: H+D score ≥ 40% improvement
Measured: Baseline and end of Treatment (up to 14 Weeks)
