Edgewise Industry Forum with Key Opinion Leaders

On March 4, 2024, at 12 pm ET, Edgewise is sponsoring an Industry Forum, “Protecting and preserving dystrophic muscle: The balance between exercise and contraction-induced muscle injury.” The forum will feature presentations by leading neuromuscular disease experts, John Vissing, M.D., Ph.D., Professor of Neurology, Director Neuromuscular Clinic and Research Unit, Department of Neurology, University of Copenhagen, and Tanja Taivassalo, Ph.D., Associate Professor, Department of Physiology and Aging, University of Florida, as well as Edgewise Chief Medical Officer, Joanne Donovan, M.D., Ph.D. Only registered conference attendees can register for the symposium.

About EDG-5506 for Duchenne and Becker Muscular Dystrophies

EDG-5506 is an orally administered small molecule designed to prevent contraction-induced muscle damage in dystrophinopathies including Duchenne and Becker. 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 minimizing the progressive muscle damage that leads to functional impairment, EDG-5506 has the potential to benefit a broad range of patients suffering from debilitating neuromuscular disorders. Its unique mechanism of action provides the potential to establish EDG-5506 as a foundational therapy in dystrophinopathies, either as a single agent therapy or in combination with available therapies and those in development. The Company is advancing EDG-5506 through the clinic including completing enrollment of a Phase 2 trial cohort, called CANYON, evaluating safety and effects on function and biomarkers of muscle damage in adult males with Becker, which has been expanded to include an additional 120 adult participants in a pivotal cohort called GRAND CANYON, which is currently enrolling. In Duchenne, the Company is advancing its Phase 2 clinical trials, LYNX, assessing safety, pharmacokinetics and biomarkers of muscle damage, and FOX, which includes children and adolescents previously treated with gene therapy.
