Frequently asked questions about EDG-15400

What is EDG-15400?

EDG-15400 is an investigational small molecule developed by Edgewise Therapeutics, Inc. for heart failure with preserved ejection fraction, a form of heart failure in which the heart's pumping function appears normal but it struggles to fill properly. It is in Phase 2 clinical development and has not been approved by the FDA.

What is EDG-15400 used for in heart failure with preserved ejection fraction?

EDG-15400 is being studied as a treatment for heart failure with preserved ejection fraction, or HFpEF. The Phase 2 EQUINOX-HFpEF trial is evaluating the drug in adults aged 30 years and older with this condition. It remains investigational and is not approved for any use.

What does EDG-15400 target?

EDG-15400 targets a cardiac sarcomeric protein, a component of the heart's contractile machinery. The specific molecular target has not been disclosed. Modulating sarcomeric function is the intended approach for addressing the impaired cardiac filling that characterizes heart failure with preserved ejection fraction.

Who makes EDG-15400?

EDG-15400 is being developed by Edgewise Therapeutics, Inc., a biopharmaceutical company that trades on the Nasdaq under the ticker symbol EWTX. Edgewise is the sponsor of the Phase 2 EQUINOX-HFpEF study evaluating the drug in heart failure with preserved ejection fraction.

What phase is EDG-15400 in?

EDG-15400 is in Phase 2 clinical development. It is investigational and has not been approved by the FDA. The ongoing Phase 2 EQUINOX-HFpEF trial is currently recruiting participants and is the only clinical trial of EDG-15400 listed for the program.

What clinical trials is EDG-15400 in?

EDG-15400 is being evaluated in the Phase 2 EQUINOX-HFpEF trial, registered as NCT07795814. The study is titled A Study of EDG-15400 in Adults With Heart Failure With Preserved Ejection Fraction. It is recruiting in the United States, is randomized, double blind, and placebo controlled, and plans to enroll 90 participants.
