About EDG-5506 for Becker and Duchenne 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 genetic 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 Becker.

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 Becker (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 following 12 months of treatment with EDG-5506. The Phase 2 trial of EDG-5506 in Becker (CANYON) has been expanded to include an additional 120 adult participants in a pivotal cohort called GRAND CANYON. CANYON is fully enrolled; GRAND CANYON is currently enrolling. LYNX, an ongoing Phase 2 trial (NCT05540860), is assessing safety, PK and biomarkers of muscle damage in participants with Duchenne. The Company is also continuing to recruit the DUNE Phase 2 exercise challenge study, to evaluate the effect of EDG-5506 on biomarkers of muscle damage following exercise in adults with LGMD2I, Becker or McArdle disease at a single site in Denmark.
