Edgewise Therapeutics to Present on Sevasemten (EDG-5506) for Becker Muscular Dystrophy (Becker) at the 29th International Annual Congress of the World Muscle Society

Edgewise Therapeutics, Inc., (Nasdaq: EWTX), a leading muscle disease biopharmaceutical company, today announced its participation at the 29th International Annual Congress of the World Muscle Society (WMS) with an industry-sponsored symposium and the presentation of seven scientific posters. These presentations will highlight the effects of sevasemten in individuals with Becker based on findings from the DUNE and ARCH clinical trials, as well as provide perspectives on biomarker and functional endpoints being studied in the CANYON Phase 2 trial. Sevasemten is an orally administered small molecule designed to prevent contraction-induced muscle damage in muscular dystrophies including Becker and Duchenne muscular dystrophy. The conference will take place at The Prague Congress Centre in Prague, Czechia, October 8-12, 2024.

Details of the Edgewise symposium and scientific posters at WMS:

Edgewise Symposium with Key Opinion Leaders

Date: Tuesday, October 8, 2024, at 4:30 pm CEST

Title: Understanding disease progression and a potential novel agent to protect muscle

Presenters: Luca Bello, M.D., Ph.D, Associate Professor, Department of Neurosciences, DNS, University of Padova and Craig McDonald, M.D., Professor and Chair, Department of Physical Medicine & Rehabilitation, Professor of Pediatrics, Director MDA Neuromuscular Disease Clinics, University of California Davis.

The symposium will also include discussion of the positive two-year topline results from the ARCH trial, an open label, single-center study assessing safety, tolerability, impact on muscle damage biomarkers, pharmacokinetics (PK) and functional measures with sevasemten in adults with Becker. Only registered conference attendees can register for the symposium.

About Sevasemten for Becker and Duchenne Muscular Dystrophies

Sevasemten is an orally administered small molecule designed to prevent contraction-induced muscle damage in dystrophinopathies including Becker and Duchenne. Sevasemten 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, sevasemten has the potential to benefit a broad range of patients suffering from debilitating neuromuscular disorders.

In Becker, after completion of the two-year Phase 1 ARCH trial, the Company continues to advance sevasemten through the clinic with the Phase 2 CANYON trial, which is fully enrolled, evaluating safety and effects on function and biomarkers of muscle damage in adult males with Becker. The Company expects to report CANYON data in the fourth quarter of 2024. The CANYON trial has expanded to include an additional 120 adult participants in a pivotal cohort GRAND CANYON, which is currently enrolling in the United States, Europe, Israel, Australia and New Zealand. Data from GRAND CANYON, if positive, could support a marketing application.

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. The Company expects to report LYNX data in the fourth quarter of 2024. The Company will rely on LYNX data, along with data from the FOX trial of Duchenne children previously treated with gene therapy, to guide the design and powering of a Phase 3 trial in Duchenne, planned to be initiated in the first half of 2025.
