MapLight Therapeutics, a Redwood City-based biopharmaceutical company, has announced the initiation of a Phase 2 clinical trial to evaluate the efficacy, safety, and tolerability of its investigational M1/M4 muscarinic agonist, ML-007C-MA, for the treatment of Alzheimer's disease psychosis (ADP). The Phase 2 VISTA study is a randomized, double-blind, placebo-controlled trial designed to enroll approximately 300 patients MapLight Therapeutics Announces Initiation of Phase 2 Trial of Novel M1/M4 Muscarinic Agonist ML-007C-MA for the Treatment of Alzheimer’s Disease Psychosis[1].

The study aims to assess the change in the Neuropsychiatric Inventory - Clinician Rating Scale Hallucinations and Delusions (NPI-C H+D) score from baseline to Week 7, with the primary endpoint being the efficacy of ML-007C-MA in reducing hallucinations and delusions associated with ADP. The trial is expected to provide results in the second half of next year, aligning with the company's mid-stage trial timeline MapLight Therapeutics Announces Initiation of Phase 2 Trial of Novel M1/M4 Muscarinic Agonist ML-007C-MA for the Treatment of Alzheimer’s Disease Psychosis[1].
