Scholar Rock is a clinical-stage biopharmaceutical company focused on the discovery and development of innovative medicines for the treatment of serious diseases in which signaling by protein growth factors plays a fundamental role. Our most advanced investigational product candidate, apitegromab (SRK-015), a selective inhibitor of the activation of the growth factor myostatin in skeletal muscle, is in development for the treatment of spinal muscular atrophy, or SMA. Following positive results from the TOPAZ Phase 2 trial in patients with Type 2 and Type 3 SMA, we are now advancing apitegromab development through SAPPHIRE, a randomized, double-blind, placebo-controlled, phase 3 clinical trial. In addition, we are conducting our DRAGON Phase 1 proof-of-concept trial for SRK-181, a selective inhibitor of latent TGFβ1 activation, in patients with locally advanced and metastatic solid tumors. Utilizing our proprietary platform, we are creating a pipeline of novel product candidates with the potential to transform the lives of patients suffering from a wide range of serious diseases, including neuromuscular disorders, cancer, fibrosis and anemia.
