Scholar Rock Achieves First Milestone in Strategic Fibrosis Collaboration with Gilead Sciences

Successful demonstration of preclinical in vivo proof-of-concept studies advances collaboration to develop highly specific inhibitors of TGFß activation for the potential treatment of patients suffering from fibrotic diseases

Discovery efforts have yielded potent and selective inhibitors of latent TGFß activation for fibrosis indications  

Scholar Rock earns $25 million with achievement of initial milestone; eligible to receive up to an additional $1,425 million in potential payments from Gilead

CAMBRIDGE, Mass., Jan. 09, 2020 (GLOBE NEWSWIRE) -- 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 Company has earned a $25 million milestone payment from Gilead Sciences, Inc. (NASDAQ: GILD) for the successful demonstration of efficacy in preclinical in vivo proof-of-concept studies. This is the most advanced program of the collaboration focused on the discovery and development of potent and selective inhibitors of latent transforming growth factor beta (TGFß) activation for the treatment of fibrotic diseases.

“Achieving this important first milestone at the one year mark of the collaboration is indicative of the progress we are making together towards unlocking the potential of this novel approach to TGFß inhibition in the treatment of patients suffering from fibrotic diseases,” said Nagesh Mahanthappa, Ph.D., President and CEO of Scholar Rock. “This accomplishment further validates the broad applicability of our platform by targeting the activation of latent growth factors to overcome historic challenges with selectivity and to discover and develop safe and effective therapeutics to address a wide range of serious diseases, including neuromuscular disorders, cancers, fibrosis, and anemia.”

The collaboration between Gilead and Scholar Rock was established in December 2018 to discover and develop therapeutics that target TGFß-driven signaling, a central regulator of fibrosis. Scholar Rock retains exclusive worldwide rights to discover, develop, and commercialize certain TGFß inhibitors for oncology and cancer immunotherapy. 

Scholar Rock received $80 million in upfront payments in connection with the collaboration, comprised of $50 million cash and $30 million purchase of Scholar Rock Holding Corporation common stock. In addition to this one-time $25 million preclinical milestone, Scholar Rock is eligible to receive up to an additional $1,425 million in potential payments from Gilead aggregated across all three programs based on the successful achievement of certain research, development, regulator and commercialization milestones. Scholar Rock would also receive high single-digit to low double-digit tiered royalties on sales of potential future products originating from the collaboration.

Under the collaboration, Gilead has exclusive options to license worldwide rights to product candidates that emerge from three Scholar Rock TGFß programs: inhibitors that target activation of latent TGFß1 with high affinity and specificity, inhibitors that selectively target activation of latent TGFß1 localized to extracellular matrix, and a third TGFß discovery program. Scholar Rock is responsible for antibody discovery and preclinical research through product candidate nomination, after which, upon exercising the option for a program, Gilead will be responsible for the program’s preclinical and clinical development and commercialization.

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. The Company’s two lead product candidates include SRK-015, a selective inhibitor of the activation of myostatin, for the treatment of patients with Spinal Muscular Atrophy and SRK-181, an isoform-selective inhibitor of TGFß1 activation as a cancer immunotherapy in combination with anti-PD(L)1 antibodies. Scholar Rock’s newly elucidated understanding of 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.
