Drug Name: Cutamesine
Company: M’s Science Corporation
Location: Japan
Drug Type: Small Molecule
Conditions: ALS, depression, stroke
Mechanism Type: Sigma-1 receptor (S1R) agonist
Mechanism: Cutamesine is a highly selective sigma-1 receptor (S1R) agonist, which is being developed for ALS. S1R mutations are associated with juvenile ALS, and mouse studies suggest S1R agonists may have therapeutic benefit in ALS.
U.S. Status for ALS: N/A
