CAMBRIDGE, Mass.--(BUSINESS WIRE)--March 7, 2022--Scholar Rock (NASDAQ: SRRK), a clinical-stage biopharmaceutical company focused on the treatment of serious diseases in which protein growth factors play a fundamental role, today reported financial results for the full year ended December 31, 2021, and highlighted recent progress and upcoming milestones for its pipeline programs.

“We are excited by the momentum and engagement around our ongoing Phase 3 SAPPHIRE trial of apitegromab in spinal muscular atrophy, as well as our DRAGON Phase 1 trial of SRK-181 in solid tumors. These programs have significant potential to address unmet patient need in a differentiated way, as well as demonstrate the tremendous potential of Scholar Rock’s platform, which focuses on inhibiting the activation of latent growth factors,” said Nagesh Mahanthappa, Interim Chief Executive Officer of Scholar Rock. “While we progress these clinical programs, we also continue to build upon our world-leading expertise in selectively targeting the activation mechanisms of the TGFβ-superfamily growth factors and advance our preclinical pipeline focused on diseases such as fibrosis and regulation of iron metabolism. We look forward to providing more details about these programs at scientific meetings and through publications in the coming months.”
