About this study

The study is being done to see if ziltivekimab can be used to treat participants living with heart failure and inflammation. Participants will either get ziltivekimab (active medicine) or placebo (inactive substance that looks like the study medicine but does not contain any medicine). The treatment participants get is decided by chance. Participant's chance of getting ziltivekimab or placebo is the same. Ziltivekimab is not yet approved in any country or region in the world. It is a new medicine that doctors cannot prescribe. The study is expected to last for up to 1 year and 4 months.

Sponsor: Novo Nordisk A/S

You may qualify if…

  • Serum high-sensitivity C-reactive protein (hs-CRP) greater than or equal to 2 milligrams per liter (mg/L) at screening (visit 1)
  • Disease specific - cardiovascular:
  • N-terminal-pro-brain natriuretic peptide (NT-proBNP) greater than or equal to 225 picograms per milliliter (pg/mL) (375 pg/mL for participants with atrial fibrillation/flutter) at screening
  • Diagnosis of heart failure (New York heart association (NYHA) Class II-III)
  • Left ventricular ejection fraction (LVEF) greater than 40 percent documented by echocardiography within 12 months prior to or at screening (visit 1). The LVEF must be documented in medical records and the most recent measurement must be used to determine eligibility with no interim event signalling potential deterioration in ejection fraction (example myocardial infarction (MI) or heart failure (HF) hospitalisation)
  • Structural heart disease and/or functional heart disease documented by echocardiography within 12 months prior to or at screening (visit 1) showing at least one of the following:
  • 1. Left atrial (LA) volume index greater than 34 milliliter per square meter (mL/m\^2)
  • 2. LA diameter greater than or equal to 3.8 centimeter (cm)

You may not qualify if…

  • Medical conditions - cardiovascular:
  • Myocardial infarction, stroke, unstable angina pectoris, transient ischaemic attack, or heart failure hospitalisation within 30 days prior to screening (visit 1)
  • Systolic blood pressure greater than or equal to 180 millimeters of mercury (mmHg) at screening (visit 1). If the systolic blood pressure is 160-179 mmHg, the patient should be receiving greater than or equal to 3 antihypertensive drugs
  • Heart rate above 110 or below 40 beats per minute as evaluated on the Electrocardiogram (ECG) performed at screening (visit 1)
  • Planned coronary, carotid or peripheral artery revascularisation known during the screening period (visit 1)
  • Planned cardiac device or atrial flutter/atrial fibrillation ablation procedure known during the screening period (visit 1)
  • Major cardiac surgical, non-cardiac surgical, or major endoscopic procedure (thoracoscopic or laparoscopic) within the past 60 days prior to randomisation (visit 2) or any major surgical procedure planned at the time of randomisation (visit 2)
  • Heart failure due to infiltrative cardiomyopathy (e.g., sarcoid, amyloid), arrhythmogenic right ventricular cardiomyopathy, Takutsubo cardiomyopathy, genetic hypertrophic cardiomyopathy or obstructive cardiomyopathy, active myocarditis, constrictive pericarditis, cardiac tamponade, uncorrected more than moderate primary valve disease
