The purpose of this study is to evaluate inclisiran sodium 300 mg s.c. (equivalent to 284 mg inclisiran) compared to placebo on reducing the risk of 4P-MACE in adult patients at high risk for their first major adverse cardiovascular event.~Randomized participants will receive study medication (inclisiran or placebo), administered s.c. on Day 1, Day 90, then every 6 months thereafter. This is an event-driven study. Therefore, the study will continue until the required number of clinical events have occurred across both treatment arms, and all participants have a minimum of 3 years of follow-up during the double-blind treatment period.
CKJX839D12302 is a pivotal Phase III study designed to test the hypothesis that treatment with inclisiran sodium 300 milligram (mg) subcutaneous (s.c.) administered on Day 1, Day 90, and every 6 months thereafter in patients at high cardiovascular (CV) risk without a prior major atherosclerotic cardiovascular disease (ASCVD) event will significantly reduce the risk of 4-Point-Major Adverse Cardiovascular Events (4P-MACE) defined as a composite of CV death, non-fatal myocardial infarction (MI), non-fatal ischemic stroke, and urgent coronary revascularization, compared to placebo.
