losmapimod

Small moleculeexperimental

Losmapimod (GW856553X) is an investigational drug that reached stage III clinical trials for multiple medical conditions, but did not prove efficacy. It was most recently in development by Fulcrum Therapeutics for the treatment of facioscapulohumeral muscular dystrophy (FSHD). Losmapimod selectively inhibits enzymes p38α/β mitogen-activated protein kinases (MAPKs), which are modulators of DUX4 expression and mediators of inflammation. — Wikipedia
