A Phase 3, Randomized, Double-Blind, Placebo-Controlled Study to Investigate the Effect of Lepodisiran on the Reduction of Major Adverse Cardiovascular Events in Adults With Elevated Lipoprotein(a) Who Have Established Atherosclerotic Cardiovascular Disease or Are at Risk for a First Cardiovascular Event - ACCLAIM-Lp(a)

The purpose of this study is to evaluate the efficacy of lepodisiran in reducing cardiovascular risk in participants with high lipoprotein(a) who have cardiovascular disease or are at risk of a heart attack or stroke. The study drug will be administered subcutaneously (SC) (under the skin). Approximately 1700 additional participants will be enrolled in an addendum to explore Lp(a) lowering with an alternative dosing schema.
