– Phase 2 trial evaluating EDG-15400 in adults with symptomatic HFpEF with a LVEF of at least 50% – – EQUINOX-HFpEF trial design and EDG-15400 Phase 1 first-in-human data to be presented at HFSA 2026 – BOULDER, Colo., Oct. 8, 2026 /PRNewswire/ -- Edgewise Therapeutics, Inc. (Nasdaq: EWTX), a leading clinical-stage biopharmaceutical company focused on cardiometabolic diseases, today announced the dosing of the first patient in EQUINOX-HFpEF, a Phase 2 clinical trial evaluating EDG-15400 in adults with symptomatic heart failure with preserved ejection fraction (HFpEF) who have a left ventricular ejection fraction (LVEF) of at least 50%. EDG-15400 is an investigational, oral, selective cardiac sarcomere modulator that has demonstrated improvements in diastolic function in preclinical models. A product of the Edgewise cardiovascular discovery platform, EDG-15400 is intended to address impaired cardiac relaxation, a defining feature of HFpEF that contributes to symptoms and disease burden. "Dosing the first patient in the EQUINOX-HFpEF trial marks an important milestone in evaluating EDG-15400's potential to improve the impaired cardiac relaxation that characterizes HFpEF," said Kevin Koch, Ph.D., President and Chief Executive Officer of Edgewise Therapeutics. "This study seeks to extend our cardiac sarcomere platform into an underserved patient population and will help determine whether this differentiated mechanism can benefit patients with symptomatic HFpEF." "HFpEF remains one of the most challenging forms of heart failure to treat, in part because current therapies do not directly address impaired cardiac relaxation," said James L. Januzzi, M.D., Chair of the EQUINOX-HFpEF Executive Committee and the Hutter Family Professor of Medicine at Harvard Medical School. "Based on preclinical observations, EDG-15400 may represent a more direct approach to HFpEF." Phase 2 EQUINOX-HFpEF Trial of EDG-15400 EQUINOX-HFpEF is a Phase 2, multicenter, randomized, double-blind, placebo-controlled clinical trial evaluating EDG-15400 in adults with symptomatic HFpEF. The study is designed to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of EDG-15400. The trial is expected to enroll approximately 90 adults aged 30 to 84 years with HFpEF. Participants will receive once-daily oral doses of 25 mg or 50 mg of EDG-15400, or placebo, for up to 12 weeks. The study will enroll participants with HFpEF who have a LVEF of at least 50% and New York Heart Association functional class II or III symptoms.

About Heart Failure with Preserved Ejection Fraction HFpEF is a form of heart failure in which the heart's main pumping chamber retains a preserved ejection fraction but does not relax and fill normally. Diastolic dysfunction is central to HFpEF and can contribute to symptoms including shortness of breath, swelling, fatigue and weakness, substantially affecting patients' daily activities and quality of life. Despite recent treatment advances, additional therapies are needed to more directly address the underlying cardiac dysfunction associated with HFpEF. About Edgewise Therapeutics Edgewise Therapeutics is a leading biopharmaceutical company focused on developing innovative therapies for serious cardiovascular and cardiometabolic diseases. Leveraging its expertise in integrated muscle physiology and small molecule drug development, Edgewise is advancing a cardiovascular pipeline targeting significant unmet needs, including hypertrophic cardiomyopathy and heart failure.
