Edgewise Industry Forum with Key Opinion Leader

On March 21, 2023, at 12 pm CT, Edgewise is sponsoring an Industry Forum, “Targeting Fast Muscle Myosin: A Novel Approach to Protecting Muscle in the Dystrophinopathies.” The forum will feature leading neuromuscular disease expert, Barry J. Byrne, M.D., Ph.D., Associate Chair of Pediatrics and Director of the Powell Gene Therapy Center at the University of Florida, as well as Edgewise leadership including Alan Russell, Ph.D., Chief Scientific Officer, Joanne Donovan, M.D., Ph.D., Chief Medical Officer, and Sam Collins, MBBS, Ph.D., Vice President of Clinical Development. Only registered conference attendees can register for the symposium.

About EDG-5506

EDG-5506 is an orally administered small molecule designed to prevent muscle damage induced by mechanical stress in dystrophinopathies including DMD and BMD. EDG-5506 presents a novel mechanism of action designed to selectively limit the exaggerated muscle damage caused by the absence or loss of functional dystrophin. By impacting the progressive muscle damage that leads to functional impairment, EDG-5506 has the potential to benefit a broad range of patients suffering from debilitating rare neuromuscular disorders. It is anticipated to be used as a single agent therapy, but it may also provide an additional benefit in combination with available therapies and therapies currently in development. In August 2021, the U.S. Food and Drug Administration (FDA) granted Fast Track designation to EDG-5506 for the treatment of individuals with BMD.

The Company has completed a Phase 1 clinical trial of EDG-5506 designed to evaluate safety, tolerability, PK and pharmacodynamics of EDG-5506 in adult healthy volunteers (Phase 1a) and in adults with BMD (Phase 1b) (NCT04585464). In ARCH, an open-label, single-center trial (NCT05160415) assessing long-term safety and PK, decreases in biomarkers of muscle damage and trends toward improvement in NSAA have been observed. CANYON, a Phase 2 trial (NCT05291091) is assessing safety, PK, biomarkers and functional measures in participants with BMD. LYNX, a Phase 2 trial (NCT05540860) is assessing safety, PK and biomarkers of muscle damage in participants with DMD.

About Edgewise Therapeutics

Edgewise Therapeutics is a clinical-stage biopharmaceutical company focused on the discovery, development, and commercialization of innovative treatments for severe, rare neuromuscular and cardiac disorders for which there is significant unmet medical need. Guided by its holistic drug discovery approach to targeting the muscle as an organ, Edgewise has combined its foundational expertise in muscle biology and small molecule engineering to build its proprietary, muscle-focused drug discovery platform. Edgewise’s platform utilizes custom-built high throughput and translatable systems that measure integrated muscle function in whole organ extracts to identify small molecule precision medicines regulating key proteins in muscle tissue. The Company’s lead candidate, EDG-5506, an investigational orally administered small molecule designed to protect injury-susceptible fast skeletal muscle fibers in dystrophinopathies, is advancing in multiple clinical trials in individuals with Duchenne, Becker and Limb Girdle 2I/R9 muscular dystrophies, and McArdle’s disease. The Company is also advancing EDG-7500, a novel sarcomere modulator for hypertrophic cardiomyopathy, into IND-enabling preclinical development.
