What is this study?
This trial will examine if maridebart cafraglutide as an adjunct to standard of care will lead to a reduction in heart failure (HF) events such as HF hospitalizations and urgent HF visits, cardiovascular (CV) deaths and improvement in HF symptoms in participants with HF with preserved ejection fraction (HFpEF) and HF with mildly reduced ejection fraction (HFmrEF) who are obese. This is a phase 3, global, multicenter, 2-part trial with a double-blind period and an open-label extension (OLE).
It is , overseen by an independent and licensed medical staff.

This trial will examine if maridebart cafraglutide as an adjunct to standard of care will lead to a reduction in heart failure (HF) events such as HF hospitalizations and urgent HF visits, cardiovascular (CV) deaths and improvement in HF symptoms in participants with HF with preserved ejection fraction (HFpEF) and HF with mildly reduced ejection fraction (HFmrEF) who are obese. This is a phase 3, global, multicenter, 2-part trial with a double-blind period and an open-label extension (OLE). The trial is event-driven, and Part 1 will conclude when approximately 850 primary endpoint events have occurred.
Who this study is looking for
In plain language, from the study's own rules. The study team confirms the full details with you — this isn't a final yes or no.
✅ You may be able to join if…
- •Be at least 18 years old when signing consent.
- •Have obesity, defined as BMI 30.0 kg/m² or higher at randomization.
- •Have heart failure for at least 30 days, with NYHA Class II-IV symptoms at consent.
- •Be on heart failure standard of care treatments.
- •Have left ventricular ejection fraction (LVEF) greater than 40% within 12 months before randomization.
🚫 You may not be able to join if…
- •Have had certain heart problems or surgeries in the last 60 days, including type I (spontaneous) heart attack (MI), valve replacement/repair, coronary revascularization, coronary bypass surgery, or stroke.
- •Have heart failure caused by certain specific heart conditions (listed in the study), such as hypertrophic cardiomyopathy, myocarditis, constrictive pericarditis, certain cardiomyopathies/dysplasia, uncorrected primary valve disease, or significant congenital heart disease.
- •Be hospitalized for acute decompensated heart failure during the screening period.
- •Have type 1 diabetes mellitus, or diabetes other than type 2 diabetes (T2DM) or a history of gestational diabetes.
- •Meet any of several other major exclusions listed, including very high screening blood pressure, certain diabetes eye disease (if applicable), severe kidney disease/dialysis, or certain thyroid cancer family/personal history.
Are you a good fit?
Simplified highlights. The study team always confirms the full details with you.
- ✓Adults roughly 18–99
- ✓A BMI around 30 or higher

- !May require a break from current GLP-1 medications
What to expect, step by step
- 1
Usually a few weeks
The study team checks whether the study is a good fit for you, with a visit and sometimes lab tests. You can ask any questions before deciding.
- 2
Treatment
If you join and choose to continue, you receive the study treatment and are watched closely by medical staff.
- 3
Follow-up
After treatment, the team checks on your health and confirms the visit schedule with you. You can leave the study at any point.
Has this treatment been tested before?
Yes. This treatment has already been through earlier human studies for safety before reaching this stage.
What you need to know before you apply
What is this study testing?+
This trial will examine if maridebart cafraglutide as an adjunct to standard of care will lead to a reduction in heart failure (HF) events such as HF hospitalizations and urgent HF visits, cardiovascular (CV) deaths and improvement in HF symptoms in participants with HF with preserved ejection fraction (HFpEF) and HF with mildly reduced ejection fraction (HFmrEF) who are obese. This is a phase 3, global, multicenter, 2-part trial with a double-blind period and an open-label extension (OLE).
Is it safe? Who makes sure of that?+
This is a late-stage study (Phase 3), testing how well the treatment works in more people. Every study is reviewed and monitored by an independent ethics board (called an IRB) whose job is to protect participants, and care is overseen by licensed medical staff. You'll be told the known risks before you agree to anything, and you can stop at any time.
Will I get a placebo instead of the real treatment?+
Some studies compare a treatment against a placebo (an inactive version), and some don't. If this one does, the study team will explain your chances of receiving the active treatment before you decide. Nothing is hidden from you.
I take a GLP-1 medication (like Ozempic or Wegovy). Can I still join?+
Maybe. This study may ask you to pause certain weight or diabetes medications for a period of time (a 'washout') before joining, or it may be looking for people not currently on them. The coordinator will review your medications with you — don't stop any medication on your own.
Does it cost anything? Will I be paid?+
The study treatment and study-related visits are provided at no cost to you. This study may also compensate you for your time and travel — the team will tell you the amount before you join. You should never be asked to pay to take part.
Do I need insurance? Will anyone ask about my immigration status?+
No. You do not need health insurance to take part in a research study, and you will not be asked about your immigration status to join. Taking part is about whether you're a medical fit for the study.
What if English isn't my first language?+
You have the right to understand everything before you agree. Study sites can often provide materials or an interpreter in your language — you can ask the coordinator for one.
Is my information private?+
Yes. Your health information is only shared with the study sites you choose to be contacted by, and only to help match and enroll you. It is never sold, and you can ask us to delete it at any time.
Some requirements (like specific lab values or timing) are confirmed directly by the study team, not by us.
