Rationale, Design, and Baseline Clinical Characteristics of the Ziltivekimab Cardiovascular Outcomes Trial: Interleukin-6 Inhibition and Atherosclerotic Event Rate Reduction

Authors' conclusion
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.
