M1 muscarinic acetylcholine receptor Inhibitors
1 drugsAbout M1 muscarinic acetylcholine receptor
The M1 muscarinic acetylcholine receptor (M1 mAChR) is a GPCR that mediates acetylcholine neurotransmission in the central nervous system. It influences cognitive functions like learning and memory.
M1 mAChR is a therapeutic target for neurological disorders, but currently lacks genetic evidence linking it to specific diseases.
COBENFY is the only FDA-approved drug targeting M1 mAChR, developed by Bristol-Myers Squibb as a small molecule for CNS indications. It was first approved in 2024.

How We Count Trials
- Trials: phase 1-4 interventional trials on ClinicalTrials.gov that started in 2008 or later and test an FDA-approved drug acting on M1 muscarinic acetylcholine receptor. A trial counts if an approved drug acting on M1 muscarinic acetylcholine receptor is in any arm, including as a comparator, and a trial that tests two such drugs counts once. Trials that test only unapproved drugs are not counted. A trial listed as phase 1/2 counts as phase 1, and phase 2/3 as phase 2.
- Active: recruiting, not yet recruiting, enrolling by invitation, or active and no longer recruiting.
- Completion rate: of the trials that have ended, the share marked Completed rather than Terminated or Withdrawn. Completed means the trial ended as planned; it does not mean the drug worked. Suspended trials are not counted as ended.
- Stopped: terminated or withdrawn. Trials stop for many reasons, including slow enrolment and business decisions, not only safety or efficacy.
- Sponsors: the lead sponsor of each trial. Companies are the sponsors ClinicalTrials.gov classes as industry; the rest are universities, hospitals, cooperative groups, government bodies and individuals.
