– Initiation of LYNX Phase 2 clinical trial in individuals with DMD expected in Q4 2022 –
BOULDER, Colo.–(BUSINESS WIRE)– Edgewise Therapeutics, Inc., (NASDAQ: EWTX), a clinical-stage biopharmaceutical company focused on developing orally bioavailable, small molecule therapies for the treatment of rare muscle disorders, today announced that the U.S. Food and Drug Administration (FDA) has authorized a clinical trial of EDG-5506 in children with DMD. The Company expects to begin dosing participants in the LYNX Phase 2 trial in the fourth quarter of 2022. EDG-5506 is an investigational orally administered small molecule myosin modulator designed to protect injury-susceptible fast skeletal muscle fibers in dystrophinopathies such as DMD and Becker muscular dystrophy (BMD).
“This is an important achievement for our team as we seek to expand our studies with EDG-5506 into individuals with DMD. Our team has worked with key opinion leaders and patient advocacy groups to thoughtfully design our LYNX Phase 2 clinical trial,” said Joanne Donovan, M.D., Ph.D., Chief Medical Officer of Edgewise. “The promising tolerability and changes in biomarkers of muscle damage that we have seen in studies with EDG-5506 in individuals with BMD supports our next step of expanding enrollment to individuals with DMD.”
The LYNX Phase 2 trial is a placebo-controlled trial to assess the effect of three doses of EDG-5506 over 12 weeks on safety, pharmacokinetics (PK) and biomarkers of muscle damage. Approximately 27 children with DMD aged 4 to 9 years on stable corticosteroids are expected to be enrolled at up to 12 sites across the United States. Participants will then continue in an open-label extension part of the trial for a total of 12 months to gain further insights into safety and functional measures. Importantly, this trial is designed to identify the doses of EDG-5506 that have the potential to reduce biomarkers of muscle damage and provide functional benefit to patients in a Phase 3 trial.
“As observed in many neuromuscular disorders, we need to have complementary approaches to address the underlying cause of the condition,” said Pat Furlong, Founding President and Chief Executive Officer, Parent Project Muscular Dystrophy. “By Edgewise expanding from Becker to Duchenne, this adds hope for those affected by Duchenne.”
About Duchenne Muscular Dystrophy
DMD is a severe, degenerative genetic disorder characterized by progressive impairment of muscle function. DMD affects an estimated one in every 3,500–5,000 male births, with an estimated 12,000–15,000 patients in the United States and approximately 25,000 patients in Europe. DMD, the most common type of muscular dystrophy, is caused by the absence of dystrophin, a protein that protects muscle from contraction-induced damage. Nearly all boys with DMD require the use of a wheelchair by the time they are young teens. Median life expectancy for a patient with DMD is around 30 years old. There is no cure for DMD and currently limited options are available for treatment of DMD.
EDG-5506 is an orally administered small molecule designed to address 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 a synergistic or additive effect in combination with available therapies and therapies currently in development. In August 2021, the 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, a follow-on open-label, single-center trial (NCT05160415) assessing long-term safety and PK, decreases in biomarkers of muscle damage have been demonstrated. CANYON, a Phase 2 trial (NCT05291091) is assessing safety, PK, biomarkers and functional measures in participants with BMD.
