Edgewise Therapeutics Unveils the Differentiated Mechanism of Action (MoA) of its Cardiac Sarcomere Modulator EDG-7500
Edgewise Therapeutics (EWTX) will host an investor webcast on September 22, 2026, to discuss the preclinical pharmacologic profile and mechanism of action of EDG-7500, a first-in-class cardiac sarcomere modulator targeting the regulatory light chain (RLC).
Rhea-AI Summary
Edgewise Therapeutics (EWTX) will host an investor webcast on September 22, 2026, to discuss the preclinical pharmacologic profile and mechanism of action of EDG-7500, a first-in-class cardiac sarcomere modulator targeting the regulatory light chain (RLC).
Preclinical models have shown that this RLC-targeting MoA can improve cardiac relaxation while preserving systolic function and cardiac reserve, and early clinical observations in patients with symptomatic hypertrophic cardiomyopathy have been consistent with these findings. The company screened more than 7,000 pharmacologically diverse RLC candidates to identify molecules with positive lusitropic properties without systolic liabilities. A peer-reviewed publication detailing EDG-7500’s MoA is expected later today, with a link to be posted on the Edgewise website. The webcast, accompanied by a slide presentation, will focus on the RLC as a unique target for symptomatic heart failure.

- The MoA that targets the Regulatory Light Chain (RLC) has shown in preclinical models to improve cardiac relaxation while preserving systolic function and cardiac reserve -
- Company to host webcast to discuss these findings today at 8:30 a.m. Eastern Time -
"We screened more than 7,000 pharmacologically diverse RLC candidates and selected molecules that exhibited positive lusitropic properties without systolic liabilities," said Alan Russell, Ph.D., Chief Scientific Officer of Edgewise Therapeutics. "EDG-7500's diastolic-biased profile has the potential to address a central pathologic driver of both symptomatic obstructive and nonobstructive HCM."
"Today's update highlights the strength of our cardiovascular pipeline and the momentum behind our approach to fine-tune the cardiac cycle in symptomatic heart failure," added Kevin Koch, President and Chief Executive Officer of Edgewise Therapeutics.

About EDG-7500
EDG-7500 is an investigational, oral, first-in-class cardiac sarcomere modulator designed to slow early contraction velocity and improve impaired cardiac relaxation associated with symptomatic HCM. EDG-7500 is being evaluated in obstructive and nonobstructive HCM. The Company completed a 12-week Phase 2 CIRRUS-HCM trial with EDG-7500 which was generally safe and well tolerated and showing no clinically significant changes in left ventricular ejection fraction. Edgewise expects to initiate a Phase 3 trial in the fourth quarter of 2026.
About Hypertrophic Cardiomyopathy
HCM is the most common form of genetic heart disease, affecting approximately one in 500 people, and is associated with reduced quality of life and an elevated risk of heart failure, abnormal heart rhythms, and sudden cardiac death. Individuals with HCM can become extremely limited in their functional capacity and ability to perform the activities of daily living. Commonly experienced symptoms include breathlessness, irregular heartbeat, chest pain, tiredness, dizziness, or even fainting. These symptoms are caused by excessive contraction and thickening (hypertrophy) of the left ventricular wall of the heart. Over time, the thickened muscle becomes stiff, making it difficult for the heart to relax and fill with blood (diastolic dysfunction). There are two major forms of HCM: obstructive and nonobstructive. Despite advancements in treatment options for some patients with HCM, there remains a significant unmet need for additional therapeutic approaches for patients.
