- Drug: Placebo
- Registration Number
- NCT07037459
- Lead Sponsor
- Amgen
- Brief Summary
This study 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 study with a double-blind period and an open-label extension (OLE). The study is event-driven, and Part 1 will conclude when approximately 850 primary endpoint events have occurred.

- Primary Outcome Measures
Name Time Method Time to First Occurrence of a Composite Endpoint Consisting of: CV Death or HF Events Up to approximately 35 months Heart Failure events include: hospitalization for HF or urgent HF visits.
- Secondary Outcome Measures
Name Time Method Change From Baseline in Kansas City Cardiomyopathy Questionnaire (KCCQ) Clinical Summary Score (CSS) for Participants with Baseline KCCQ-CSS Score ≤ 80 Baseline and Week 48 The KCCQ is a 23-item disease-specific measure for participants with HF, measuring the participant's perception of their health status. The KCCQ-CSS assesses symptoms and physical limitations, ranging from 0 to 100, with higher scores indicating better functioning and quality of life.
Change from Baseline in the KCCQ Total Symptom Score (TSS) for Participants with Baseline KCCQ-CSS Score ≤ 80 Baseline and Week 48 The KCCQ is a 23-item disease-specific measure for participants with HF, measuring the participant's perception of their health status. The KCCQ-TSS assesses symptom frequency and burden, ranging from 0 to 100, with higher scores indicating better functioning and quality of life.
Total Number of HF Events Including First and Recurrent HF Events Up to approximately 35 months Time to First Occurrence of a Composite Endpoint Consisting of: Myocardial Infarction (MI), Ischemic Stroke, CV Death (Major Adverse Cardiac Events), or HF Events Up to approximately 35 months Time to First Event of a Composite Nephropathy Endpoint Up to approximately 35 months The composite nephropathy endpoint consists of: persistent macroalbuminuria, persistent ≥ 40% reduction in estimated glomerular filtration rate (eGFR), onset of persistent eGFR \< 15 mL/min/1.73 m\^2, initiation of chronic renal replacement therapy (dialysis or transplantation), CV or renal death.
