For example, a myostatin antibody, MYO-029/stamulumab, was tested in broad muscle dystrophic models, including Becker’s muscular dystrophy (BMD) and facioscapulohumeral dystrophy, but failed to show clinical efficacy in elevating muscle strength (Leung et al., 2015). This evidence concerns the gene MSTN and Becker muscular dystrophy.
