Scholar Rock issued the following announcement on August 13.
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 announced that the U.S. Food and Drug Administration (FDA) has granted Rare Pediatric Disease (RPD) designation for SRK-015 for the treatment of Spinal Muscular Atrophy (SMA), a progressive, rare genetic disease that leads to motor function impairments. Scholar Rock is on track to report 6-month interim efficacy and safety data from the ongoing TOPAZ Phase 2 clinical trial of SRK-015 in patients with Type 2 and Type 3 SMA in the fourth quarter of 2020. Top-line data for the 12-month treatment period are expected in the first half of 2021.
“This Rare Pediatric Disease designation along with the previously granted Orphan Drug Designation highlights the FDA’s recognition of the unmet medical needs of patients with SMA. We continue to aim to establish SRK-015 as the potential first muscle-directed therapy to address motor function deficits that persist despite the availability of SMN upregulators,” said Yung Chyung, M.D., Chief Medical Officer of Scholar Rock. “We are encouraged by the progress of the TOPAZ Phase 2 trial and look forward to the interim read-out next quarter that will provide important insights into the potential of SRK-015 in patients with SMA.”
The FDA grants Rare Pediatric Disease designation for serious and life-threatening diseases that primarily affect children ages 18 years or younger and fewer than 200,000 individuals in the United States. If a biologics license application (BLA) for SRK-015 for the treatment of SMA is approved by the FDA, Scholar Rock may be eligible to receive a priority review voucher, which may be redeemed to obtain priority review for any subsequent marketing application or be sold or transferred.
About SRK-015
SRK-015 is a selective inhibitor of the activation of myostatin and is an investigational product candidate for the treatment of patients with spinal muscular atrophy (SMA). Myostatin, a member of the TGFβ superfamily of growth factors, is expressed primarily by skeletal muscle cells, and the absence of its gene is associated with an increase in muscle mass and strength in multiple animal species. Scholar Rock believes the inhibition of the activation of myostatin with SRK-015 may promote a clinically meaningful increase in muscle strength. A Phase 2 clinical trial in patients with Type 2 and Type 3 SMA is ongoing. The U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation (ODD) and Rare Pediatric Disease (RPD) designation, and the European Commission (EC) has granted Orphan Medicinal Product Designation, to SRK-015 for the treatment of SMA. The effectiveness and safety of SRK-015 have not been established and SRK-015 has not been approved for any use by the FDA or any other regulatory agency.
About Scholar Rock
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. Scholar Rock is 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. Scholar Rock’s approach to targeting the molecular mechanisms of growth factor activation enabled it to develop a proprietary platform for the discovery and development of monoclonal antibodies that locally and selectively target these signaling proteins at the cellular level. By developing product candidates that act in the disease microenvironment, the Company intends to avoid the historical challenges associated with inhibiting growth factors for therapeutic effect. Scholar Rock believes its focus on biologically validated growth factors may facilitate a more efficient development path.
