Fulcrum Therapeutics Inc.’s phase IIb data with losmapimod in facioscapulohumeral muscular dystrophy (FSHD) brought renewed hope for patients in what historically has proved a challenging therapeutic space. Though the firm’s oral p38 mitogen-activated protein kinase inhibitor missed its primary biomarker endpoint – changes in DUX4-driven gene expression – other indicators of benefit in the study called ReDUX4 painted a bright picture.
An interim analysis from Fulcrum Therapeutics Inc.’s phase II study of losmapimod for treating facioscapulohumeral muscular dystrophy (FSHD) produced data that pleased the CEO and displeased investors.
With a phase IIb readout coming in the third quarter of 2020, Cambridge, Mass.-based Fulcrum Therapeutics Inc. might be set up for a win in facioscapulohumeral muscular dystrophy (FSHD), a genetic muscle disorder for which there’s no treatment.
