MapLight Therapeutics Begins Phase 2 Trial for Alzheimer's Disease Psychosis Treatment

MapLight Therapeutics Initiates Phase 2 Trial for Alzheimer's Disease Psychosis

MapLight Therapeutics has recently announced the commencement of a Phase 2 clinical trial aimed at evaluating its investigational new drug, ML-007C-MA. This novel M1/M4 muscarinic agonist is positioned as a potential treatment for Alzheimer's Disease Psychosis (ADP), a serious complication that affects a substantial number of patients with Alzheimer's disease.

Background on Alzheimer's Disease Psychosis

Alzheimer's disease psychosis is characterized by symptoms such as hallucinations and delusions, which significantly impact the quality of life for patients and their caregivers. Research indicates that approximately 40% of patients with Alzheimer's experience psychotic symptoms during the course of their illness, often associated with accelerated cognitive decline and increased hospitalization rates. Unfortunately, current treatment options are limited, with no FDA-approved therapies specifically for ADP. Existing off-label uses of antipsychotics tend to have minimal effectiveness and are fraught with safety concerns, highlighting the urgent need for new therapeutic approaches.

The VISTA Study

The Phase 2 trial, referred to as the VISTA study, is designed as a randomized, double-blind, placebo-controlled trial that will assess the efficacy, safety, and tolerability of ML-007C-MA administered twice a day. In total, the study aims to enroll around 300 patients globally, with a primary endpoint focused on measuring changes in hallucination and delusion symptoms as seen on the Neuropsychiatric Inventory - Clinician Rating Scale (NPI-C H+D) by Week 7.

Dr. Christopher Kroeger, CEO and Founder of MapLight Therapeutics, emphasized the necessity for this research. He stated, "With the absence of effective FDA-approved options for ADP, the launch of the VISTA study is a significant milestone for us. The insights obtained from our Phase 1 program, which involved 270 healthy volunteers, point towards the promising potential of ML-007C-MA in treating these debilitating symptoms."

Promising Mechanism of Action

The drug ML-007C-MA, also known as ML-007C/PAC, is a fixed-dose combination of the novel M1/M4 agonist and a peripherally acting anticholinergic (PAC). This combination aims to activate both M1 and M4 receptor pathways in the central nervous system effectively. The design intends to optimize the pharmacokinetics of the components, thereby minimizing the prominent peripheral cholinergic side effects often associated with similar therapies. The preliminary results from Phase 1 have indicated a favorable safety and tolerability profile, particularly among elderly volunteers, which is very encouraging as we move forward.

Future Perspectives

The initiation of this trial opens up significant avenues for future research. Erin Foff, M.D., Ph.D., Chief Medical Officer at MapLight, noted, "Based on the preliminary data from Phase 1, we are optimistic about ML-007C-MA’s potential as a treatment for ADP. This study will deliver critical information that could change the current treatment landscape."

Furthermore, if successful, this treatment could not only provide relief for ADP but also has implications for managing schizophrenia and other neuropsychiatric disorders, as the company is also exploring the utility of ML-007C-MA in these conditions.

This initiative is part of MapLight Therapeutics' broader commitment to addressing the growing need for effective treatments targeted at specific neuropsychiatric conditions. The company aims to fill the treatment gap by focusing on circuit-specific therapies that can modulate neural pathways directly linked to such ailments.
