ClinConnect Summary

This clinical trial is studying a medicine called maridebart cafraglutide to see if it can help people with heart disease who are also overweight or obese. Specifically, the trial wants to find out if this medicine, when added to the usual treatments, can reduce serious heart problems like heart attacks, strokes, or death related to heart disease.

To join the study, participants need to be 45 years or older, have a body mass index (BMI) of 27 or higher (which means they are overweight or obese), and have a history of certain heart or blood vessel problems, such as a previous heart attack, stroke, or blocked arteries in the legs. People with recent serious heart events, certain types of diabetes, or other specific health issues won’t be eligible. Those who take part will receive either the study medicine or a placebo (a treatment with no active medicine) along with their regular care, and the researchers will monitor their heart health over time to see if the medicine makes a difference. This study is still in the planning phase and is not yet recruiting participants.

• • History of proliferative diabetic retinopathy, diabetic maculopathy, or severe non-proliferative diabetic retinopathy.
• • Use of any glucagon-like peptide-1 receptor agonist (GLP-1 RA), glucose-dependent insulinotropic polypeptide (GIP) agonists or antagonists, or amylin analogs within 90 days before randomization or planned use during the conduct of the study.
