About This Trial

ML-007C-MA-221 is a Phase 2, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of ML-007C-MA in male and female participants aged 55 to 90 years with hallucinations and delusions associated with Alzheimer's Disease Psychosis (ADP). The primary objective is to evaluate the efficacy of ML-007C-MA compared with placebo for the treatment of hallucinations and delusions associated with ADP as measured by the Neuropsychiatric Inventory-Clinician (NPI-C): Hallucinations and Delusions (H+D) score.

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Psychosis Associated With Alzheimer's Disease and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

A target enrollment of 300 participants makes this a sizable late-stage trial. Studies in this range typically have enough power to detect clinically meaningful differences from a comparator and to characterize less-common side effects.
