About this trial
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.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Serum high-sensitivity C-reactive protein (hs-CRP) greater than or equal to 2 milligrams per liter (mg/L) at screening (visit 1)
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)
Disqualifiers
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)

Treatment groups
Trial outcomes
Primary outcomes
Change in Kansas City Cardiomyopathy Questionnaire (KCCQ) clinical summary score (KCCQ-CSS)
Measured as score (score on scale; range; 0-100). The KCCQ is a disease-specific health status instrument composed of 23 items that quantify the domains of physical limitation, symptoms, self-efficacy, social limitation, and health-related quality of life limitation from heart failure. The overall summary score and all domains have been independently demonstrated to be valid, reliable, and responsive to clinical change. CSS scores range from 0 to 100 and lower scores represent more severe symptoms and/or limitations and scores of 100 indicate no symptoms, no limitations, and excellent quality of life.
Secondary outcomes
Participant achieving threshold for clinically meaningful within-participant change in KCCQ CSS (yes/no)
Measured as count of participants. The KCCQ is a disease-specific health status instrument composed of 23 items that quantify the domains of physical limitation, symptoms, self-efficacy, social limitation, and health-related quality of life limitation from heart failure. The overall summary score and all domains have been independently demonstrated to be valid, reliable, and responsive to clinical change. CSS scores range from 0 to 100 and lower scores represent more severe symptoms and/or limitations and scores of 100 indicate no symptoms, no limitations, and excellent quality of life.
Participant achieving threshold for clinically meaningful within-participant change in 6-minute walk distance (6MWD) (yes/no)
Measured as count of participants.
Participants improving 5 points or more in KCCQ-CSS (yes/no)
Measured as count of participants. The KCCQ is a disease-specific health status instrument composed of 23 items that quantify the domains of physical limitation, symptoms, self-efficacy, social limitation, and health-related quality of life limitation from heart failure. The overall summary score and all domains have been independently demonstrated to be valid, reliable, and responsive to clinical change. CSS scores range from 0 to 100 and lower scores represent more severe symptoms and/or limitations and scores of 100 indicate no symptoms, no limitations, and excellent quality of life.
Participants improving 10 points or more in KCCQ-CSS (yes/no)
Measured as count of participants. The KCCQ is a disease-specific health status instrument composed of 23 items that quantify the domains of physical limitation, symptoms, self-efficacy, social limitation, and health-related quality of life limitation from heart failure. The overall summary score and all domains have been independently demonstrated to be valid, reliable, and responsive to clinical change. CSS scores range from 0 to 100 and lower scores represent more severe symptoms and/or limitations and scores of 100 indicate no symptoms, no limitations, and excellent quality of life.
