The first presentation was a pre-specified analysis of the effect of aficamten compared to metoprolol on exercise performance in obstructive HCM (oHCM) in MAPLE-HCM (Metoprolol vs Aficamten in Patients with LVOT Obstruction on Exercise Capacity in HCM), and the second was an analysis from FOREST-HCM (Follow-up, Open-Label, Research Evaluation of Sustained Treatment with Aficamten in HCM) on the efficacy and tolerability of long-term treatment of aficamten in patients with non-obstructive hypertrophic cardiomyopathy (nHCM), simultaneously published in the Journal of Cardiac Failure.1 “The additional data from MAPLE-HCM expands our understanding of aficamten across several measures of exercise performance, with effects observed not only in peak exercise capacity, but also in submaximal exercise and recovery from exercise,” said Fady I. Malik, M.D., Ph.D., Cytokinetics’ Executive Vice President of Research & Development. “Additionally, the long-term data from FOREST-HCM in patients with nHCM show sustained improvements in both patient symptom burden and cardiac biomarkers associated with aficamten. Most patients achieved the highest doses available without any early treatment discontinuations, giving us confidence in the dosing strategy and the potential of aficamten to benefit patients with nHCM, as is being assessed in the ongoing Phase 3 clinical trial, ACACIA-HCM.” Pre-Specified Analysis of Supplemental Endpoints from MAPLE-HCM Shows Aficamten Improves Measures of Submaximal and Maximal Exercise Performance and Post-Exercise Recovery Compared to Metoprolol Gregory Lewis, M.D., Jeffrey and Mary Ellen Jay Chair and Section Head, Heart Failure Medical Director, Cardiopulmonary Exercise Testing (CPET) Laboratory, Professor of Medicine, Ha...
