CAMBRIDGE, Mass.--(BUSINESS WIRE) - August 6, 2026 - Scholar Rock (NASDAQ: SRRK), a global biopharmaceutical company dedicated to improving the lives of patients with rare, severe, and debilitating neuromuscular diseases by applying its leading platform in myostatin biology, today reported financial results for the second quarter ended June 30, 2026, and provided an update on recent company developments.
“We are on the threshold of securing the world’s first ever regulatory approval of a myostatin inhibitor, which will also be the first ever muscle-targeted treatment for children and adults living with SMA,” said David L. Hallal, Board Chair and Chief Executive Officer of Scholar Rock. “Backed by a strong balance sheet, our Scholar Rock team is ready to usher in the next phase of innovation for the SMA community in the U.S. immediately upon apitegromab approval.”
Business Highlights and Upcoming Milestones
Apitegromab
Apitegromab is an investigational fully human monoclonal antibody designed to inhibit myostatin activation by selectively binding the pro- and latent forms of myostatin in skeletal muscle. It is the first and only muscle-targeted therapeutic candidate in SMA to demonstrate a statistically significant and clinically meaningful benefit in a pivotal Phase 3 clinical trial (SAPPHIRE).
SMA Program
Apitegromab Biologics License Application (BLA) on track for potential FDA approval by September 30, 2026 Prescription Drug User Fee Act (PDUFA) date. The FDA review of the apitegromab BLA is advancing with both the Catalent Indiana fill-finish facility and a second fill-finish facility, representing two independent paths to an FDA approval decision. At the March 2026 Type C meeting, FDA and Scholar Rock agreed to the data package required for FDA review of the second fill-finish facility. That data package has been submitted, and Agency review of the data is progressing well. Ample supply from the second fill-finish facility is available for commercialization upon FDA approval. The FDA inspection classification of Catalent Indiana following an April 2026 general site inspection is pending.
U.S. Commercial team prepared to launch apitegromab upon FDA approval. The U.S. Commercial team remains active in the field with SMA prescribers and centers of excellence nationwide, furthering disease education and awareness initiatives. The Company had a significant presence at Cure SMA’s Annual SMA Conference and Annual SMA Research & Clinical Care Meeting, which was held June 23 - 28, 2026 in Orlando, FL.
Scholar Rock engaging with European Medicines Agency (EMA) on next steps for apitegromab Marketing Authorisation Application (MAA). The EMA is reviewing the apitegromab MAA, which includes the Catalent Indiana fill-finish facility, and is awaiting the FDA inspection classification of Catalent Indiana. In parallel, Scholar Rock is engaging with the EMA on next steps, including the potential to add the Company’s second fill-finish facility to the MAA. The Company plans to provide updated guidance on timelines for a Committee for Medicinal Products for Human Use (CHMP) opinion upon alignment with the EMA.
Continued robust enrollment in Phase 2 OPAL trial. Enrollment and dosing in the Phase 2 OPAL study is ongoing (NCT07047144). The OPAL study is evaluating apitegromab in infants and toddlers with SMA under two years of age who have received an approved SMN1-targeted gene therapy or who are receiving ongoing treatment with an approved SMN2-targeted therapy.
Subcutaneous apitegromab progressing. Scholar Rock has developed a high concentration subcutaneous formulation of apitegromab. The Company plans to engage with the FDA and EMA to align on the development path following the regulatory approvals of apitegromab for SMA.
Facioscapulohumeral Muscular Dystrophy (FSHD) Program
Phase 2 FORGE trial initiated. The Phase 2 randomized, double-blind, placebo-controlled trial, called FORGE, is expected to enroll approximately 60 patients with FSHD who will be randomized 1:1 to receive either apitegromab 10mg/kg IV or placebo every 4 weeks for 52 weeks. The primary endpoint is mean lean muscle volume (LMV) change from baseline at 12 months. Secondary endpoints include safety, pharmacokinetics/pharmacodynamics, and mean LMV change from baseline at 6 months. Several exploratory functional endpoints will also be assessed.
SRK-439
SRK-439 is a novel, investigational, subcutaneously administered myostatin inhibitor that binds to pro- and latent myostatin with high affinity and selectivity. Based on preclinical data, SRK-439 has the potential to potently inhibit myostatin and increase muscle mass.
Phase 1 study in healthy volunteers ongoing. A Phase 1 study evaluating SRK-439 in healthy volunteers is progressing well with topline data anticipated in late 2026.
