BOULDER -
ARCH is an open label, single-center study assessing safety, tolerability, impact on muscle damage biomarkers, pharmacokinetics (PK) and functional measures with sevasemten (EDG-5506) in adults with Becker. Sevasemten is an orally administered small molecule designed to prevent contraction-induced muscle damage in dystrophinopathies including Becker and Duchenne muscular dystrophy (Duchenne).
The ARCH trial evaluated sevasemten administered daily over two years in adults with Becker. Sevasemten was well-tolerated in all 12 participants with no discontinuations or dose reductions due to adverse events.
Preserving NSAA functions that correlate to activities of daily living are important to individuals living with Becker.
In addition, significant decreases in key biomarkers of muscle damage including CK and TNNI2 were observed in participants treated with sevasemten, which are consistent with prior observations.
'We are pleased by the promising and consistent functional results observed over two years of treatment with sevasemten, together with the favorable safety and tolerability profile,' said
'Becker is a devastating neuromuscular disease that currently has no treatment,' said
The positive results from the two-year ARCH trial further support the hypothesis that a reduction in contraction-induced muscle damage in muscular dystrophies has the potential to preserve function and halt disease progression in Becker.
About the ARCH Open-Label Trial
ARCH, an open-label, single-center trial, assessed sevasemten in 12 adult males with Becker. The trial evaluated sevasemten administered daily over two years. Safety, tolerability, PK, changes in biomarkers of muscle damage such as CK and fast skeletal muscle troponin I, measures of function and patient-reported outcomes were evaluated.
About GRAND CANYON, a Global Pivotal Study in Becker
The Company is advancing GRAND CANYON, a global pivotal study of EDG-5506 in individuals with Becker. GRAND CANYON is an expansion of the CANYON placebo-controlled trial. CANYON, which was over-enrolled, includes cohorts of 40 adults and 29 adolescents and a treatment period of 12 months. The Company expects to report CANYON data in the fourth quarter of 2024. GRAND CANYON is a multicenter, randomized, double-blind, placebo-controlled study to evaluate the safety and efficacy of EDG-5506 in adults with Becker. Data from GRAND CANYON, if positive, could support a marketing application. The primary endpoint of GRAND CANYON is NSAA. In addition, other functional assessments, biomarkers of muscle damage and safety will be assessed. GRAND CANYON is anticipated to recruit approximately 120 individuals with Becker, aged between 18 and 50 years old, at up to 50 sites in 10 countries. The treatment period for participants will be 18 months.
About Becker Muscular Dystrophy
Becker is a rare, genetic, life-shortening, debilitating and degenerative neuromuscular disorder. The disease predominantly affects males and imposes significant physical, emotional, financial, and social impacts on the individual and their caregivers. Individuals with Becker experience contraction-induced muscle damage, which is the primary driver of muscle loss and impaired motor function in muscular dystrophies. Functional decline can begin at any age, and once that muscle loss occurs, the decline in function is irreversible and continues throughout the individual's life. Some individuals living with Becker experience heart failure from cardiomyopathy, which may result in heart transplantation or early death. Currently, there is no cure for Becker; early and long-term multidisciplinary care is critical for optimized disease management. There is a great need for more Becker-specific scientific research, clinical programs, and treatment guidelines to improve management of this disease.
About Sevasemten (EDG-5506) 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. Its unique mechanism of action provides the potential to establish sevasemten as a foundational therapy in dystrophinopathies, either as a single agent therapy or in combination with available therapies and those in development.
In Becker, Edgewise is advancing sevasemten in a Phase 2 trial, called CANYON, evaluating safety and effects on function and biomarkers of muscle damage in adult males with Becker. The CANYON trial, which is fully enrolled, has been expanded to include an additional 120 adult participants in a pivotal cohort called GRAND CANYON. This study is currently enrolling at sites in
In Duchenne, Edgewise is advancing its LYNX Phase 2 clinical trial, assessing safety, PK, biomarkers of muscle damage and functional measures in boys with Duchenne. It also is advancing a second Phase 2 trial, called
