Scholar Rock to Present Apitegromab Clinical Data from the TOPAZ Phase 2 Trial in Patients with Type 2 and 3 Spinal Muscular Atrophy at the 2021 Virtual SMA Research & Clinical Care Meeting
- Lead principal investigator, Dr. Thomas Crawford, to present TOPAZ results showing apitegromab’s therapeutic potential to improve motor function in patients with Spinal Muscular Atrophy (SMA)
CAMBRIDGE, Mass.--(BUSINESS WIRE)-- 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 an oral presentation of apitegromab TOPAZ Phase 2 clinical trial results at the 2021 Virtual SMA Research and Clinical Care Meeting, being held in conjunction with Cure SMA’s Annual SMA Conference June 7-11, 2021.
Details for the virtual Cure SMA oral presentation are as follows:
- Title: TOPAZ: A Phase 2 Study to Evaluate the Efficacy and Safety of Apitegromab (SRK-015) in Patients with Later-Onset Spinal Muscular Atrophy (Type 2 and Type 3 SMA): Topline Results
- Presenter: Thomas Crawford, M.D., Co-Director, Muscular Dystrophy Association Clinic and Professor of Neurology, Johns Hopkins Medicine (Lead TOPAZ Principal Investigator)
- Clinical Drug Development Session: Virtual oral presentation on June 11, 2021 at 2:00pm CST
Scholar Rock recently announced positive 12-month top-line data from the TOPAZ Phase 2 trial (NCT03921528), which evaluated apitegromab, a selective inhibitor of myostatin activation, in patients with Type 2 and 3 SMA. The results show the transformative potential of apitegromab to further improve motor function in patients with non-ambulatory Type 2 and 3 SMA who were already receiving chronic maintenance therapy with a background SMN upregulator (nusinersen). A Phase 3 registrational trial in patients with non-ambulatory Type 2 and Type 3 SMA is anticipated to initiate by the end of 2021.
Apitegromab 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, including humans. Scholar Rock believes that inhibiting myostatin activation with apitegromab may promote a clinically meaningful improvement in motor function in patients with SMA. The U.S. Food and Drug Administration (FDA) has granted Fast Track (FTD), Orphan Drug (ODD) and Rare Pediatric Disease (RPD) designations, and the European Medicines Agency (EMA) has granted Priority Medicines (PRIME) and Orphan Medicinal Product designations, to apitegromab for the treatment of SMA. The efficacy and safety of apitegromab have not been established and apitegromab has not been approved for any use by the FDA or any other regulatory agency.
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, via SMN-dependent pathways, there continues to be a high unmet need for therapeutics that directly address muscle function.
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.
