ZEUS - A Research Study to Look at How Ziltivekimab Works Compared to Placebo in People With Cardiovascular Disease, Chronic Kidney Disease and Inflammation

Inclusion Criteria:

Chronic kidney disease defined by one of the below:

1. Estimated glomerular filtration rate (eGFR) greater than or equal to (>=) 15 and below 60 mL/min/1.73 m^2 (using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) creatinine equation)
2. Urinary albumin-to-creatinine ratio (UACR) >= 200 milligrams per gram (mg/g) and eGFR >= 60 mL/min/1.73 m2 (using the CKD-EPI creatinine equation)
3. Serum high-sensitivity C-reactive protein (hs-CRP) greater than or equal to 2 milligram per liter (mg/L)

Evidence of atherosclerotic cardiovascular disease (ASCVD) by one or more of the following:

a) Coronary heart disease defined as at least one of the following: i. Documented history of MI ii. Prior coronary revascularisation procedure iii. greater than or equal to 50% stenosis in major epicardial coronary artery documented by cardiac catheterisation or CT coronary angiography b) Cerebrovascular disease defined as at least one of the following: i. Prior stroke of atherosclerotic origin ii. Prior carotid artery revascularisation procedure iii. greater than or equal to 50% stenosis in carotid artery documented by X-ray angiography, MR angiography, CT angiography or Doppler ultrasound.

c) Symptomatic peripheral artery disease (PAD) defined as at least one of the following: i. Intermittent claudication with an ankle-brachial index (ABI) below or equal to 0.90 at rest ii. Intermittent claudication with a greater than or equal to 50% stenosis in peripheral artery (excluding carotid) documented by X-ray angiography, MR angiography, CT angiography or Doppler ultrasound iii. Prior peripheral artery (excluding carotid) revascularisation procedure iv. Lower extremity amputation at or above ankle due to atherosclerotic disease (excluding e.g. trauma or osteomyelitis).

Exclusion Criteria:

1. Clinical evidence of, or suspicion of, active infection at the discretion of the investigator.
2. Myocardial infarction, stroke, hospitalisation for unstable angina pectoris, or transient ischaemic attack within 60 days prior to randomisation (visit 2).
3. Planned coronary, carotid or peripheral artery revascularisation known on the day of randomisation (visit 2).
4. 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).
