The ZEUS randomized clinical trial will formally test the hypothesis that IL-6 inhibition with ziltivekimab will lower incident cardiovascular event rates and potentially slow kidney decline among participants with known ASCVD, CKD, and elevated hsCRP. If successful, the ZEUS trial would provide a fully novel approach for prevention of myocardial infarction, stroke, cardiovascular death, and kidney function decline among high-risk patients with CKD.
