Press Release

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Mar. 17, 2021-- 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 United States Patent Office (USPTO) issued U.S. Patent No. 10,946,036 with an expiry of June 2037. The claims of the patent broadly cover both add-on and combination therapy with a myostatin inhibitor and a neuronal corrector therapy (such as SMN upregulator therapy) for the treatment of Spinal Muscular Atrophy (SMA).

“We are delighted to have been granted this unique patent that further protects our myostatin approach to improving motor function for patients with SMA and we look forward to the top-line read-out from the apitegromab TOPAZ Phase 2 trial next quarter, which will provide additional insights on its potential to help patients with Type 2 and Type 3 SMA,” said Tony Kingsley, President and CEO of Scholar Rock. “In parallel with preclinical and clinical advancements, we will continue to build and strengthen our family of patents protecting our product candidates and our scientific platform.”

The broad claims of this therapeutic method patent are not limited to apitegromab or to add-on or combination treatment with any specific SMN upregulator therapy. Similar claims have also been granted in Japan (JP Patent No. 6823167) and in Europe (EP 3368069B1).

About SMA

Spinal muscular atrophy (SMA) is a rare, and often fatal, genetic disorder that typically manifests in young children. An estimated 30,000 to 35,000 patients are afflicted with SMA in the United States and Europe. It is characterized by the loss of motor neurons, atrophy of the voluntary muscles of the limbs and trunk and progressive muscle weakness. The underlying pathology of SMA is caused by insufficient production of the SMN (survival of motor neuron) protein, essential for the survival of motor neurons, and is encoded by two genes, SMN1 and SMN2. While there has been progress in the development of therapeutics that address the underlying SMA genetic defect, there continues to be a high unmet need for therapeutics that directly address muscle atrophy.

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.
