Phase 3 Global Study of Subcutaneous Maridebart Cafraglutide for Obese Adults with Heart Failure and Preserved or Mildly Reduced Ejection Fraction

What this Trial Is About

Researchers are evaluating maridebart cafraglutide as an additional treatment to standard care for adults with heart failure who have preserved or mildly reduced ejection fraction, and who are also obese. This phase 3, global, multicenter trial aims to see if this drug can reduce heart failure events like hospitalizations and urgent visits, lower cardiovascular deaths, and improve heart failure symptoms. The study has a double-blind phase and an open-label extension, and it will continue until about 850 primary endpoint events occur. Participants will be randomly assigned to receive either maridebart cafraglutide or a placebo, both given by subcutaneous injection. The trial lasts up to approximately 35 months and includes assessments at various time points to measure heart failure events, cardiovascular deaths, kidney function, blood pressure, weight, blood sugar, cholesterol, and quality of life using questionnaires. The study also tracks serious adverse events and drug concentrations. During the trial, participants will have regular visits for monitoring, including questionnaires, laboratory tests, and physical assessments. Researchers will evaluate the time to first cardiovascular events and heart failure hospitalizations as the main outcome. Secondary measures include changes in symptoms, kidney health, blood pressure, and metabolic factors. Safety will be monitored throughout, with follow-up continuing up to about 35 months from the start of treatment.
