Metabolic Modulation in Non-Obstructive HCM: Exploring the FORTITUDE Trial

In this episode of In the Thick of It, hosts Dr. Betty Raman and Dr. James MacNamara welcome Professor Martin Maron, Director of the Hypertrophic Cardiomyopathy Center at Lahey Hospital & Medical Center, to discuss the innovative FORTITUDE-HCM study. This Phase 2b trial focuses on the symptomatic non-obstructive HCM population—a group considered to have one of the greatest unmet treatment needs in the field. The conversation explores the unique mechanism of ninerafaxstat, a metabolic modulator that shifts energy utilization from fatty acids to glucose to improve cardiac energetics and diastolic relaxation. Professor Maron highlights the promising results from the earlier IMPROVE-HCM trial, details the 12-week design of the current study, and speculates on a future where "combination therapy" becomes the standard of care for complex HCM cases.
