Phase 2
Recruiting
Conditions
Alzheimer's Disease Psychosis
Interventions
Drug: Placebo
Registration Number
NCT06159673
Lead Sponsor
ACADIA Pharmaceuticals Inc.
Brief Summary

This is a master protocol for 3 independent, seamlessly enrolling, multicenter, randomized, double-blind, placebo-controlled, parallel-group studies in patients with ADP

* Substudy 1 (Phase 2) will evaluate efficacy and dose response of ACP-204 30 and 60 mg vs placebo. This substudy will be initiated first.

* Substudies 2A and 2B (both: Phase 3) will be confirmatory studies of either both doses (ACP-204 30 and 60 mg, respectively) or a single dose from Part 1 vs placebo. Substudies 2A and 2B will be performed independently of each other and will commence after enrollment of Part 1.

All 3 substudies will be analyzed independently of each other.

Each substudy individually will consist of a screening period (up to 49 days); a double-blind treatment period (6 weeks); a safety follow-up period (30 days) for patients not rolling over into an open-label extension study; and vital status follow-up (for patients who terminated their substudy early).

Primary Outcome Measures
NameTimeMethod
Scale for the Assessment of Positive Symptoms-Hallucinations and Delusions subscales (SAPS-H+D) total score change from baseline (Substudies 1, 2A, 2B)From baseline to Week 6

The SAPS-H+D subscales are a measure of two psychotic symptoms: hallucinations and delusions. The SAPS-H+D total score is the sum of the scores of the Hallucinations and Delusions subscales. The hallucinations domain score (SAPS-H) is the sum of the 7 hallucinations item scores, and the delusions domain core (SAPS-D) is the sum of the 13 delusions item scores.

Secondary Outcome Measures
NameTimeMethod
Clinical Global Impression-Improvement in the ADP context (CGI-I-ADP) scoreWeek 6

The CGI-I scale is a clinician-rated, 7-point scale used to rate the improvement in symptoms at the time of assessment, relative to the symptoms at Baseline. The CGI-I-ADP scale is the CGI-I scale applied in the ADP context, in which hallucinations and delusions are the symptoms of interest.
