The study is testing the effect of ziltivekimab on reducing plaque in the blood vessels of the heart, specifically aiming to manage or reduce atherosclerotic plaque. The purpose of the study is to determine whether ziltivekimab can effectively reduce this plaque. Participants will either receive ziltivekimab (the active medicine) or a placebo (a dummy medicine with no effect on the body), with the treatment assignment decided by chance. It is important to note that ziltivekimab is not yet approved in any country or region worldwide; therefore, it is a new medicine that doctors cannot prescribe. The study will last for about 15 months.
