Phase 3 Study of Lepodisiran to Reduce Coronary Artery Plaque in Adults Aged 45-80 With High Lipoproteina and Heart Disease or Risk

What this Trial Is About

This trial investigates adults aged 45 to 80 with elevated Lipoproteina Lpa levels, who either have existing cardiovascular disease or are at risk for a first cardiovascular event. The study aims to evaluate how lepodisiran, compared to a placebo, affects the amount and type of plaque in the coronary arteries using Coronary Computed Tomography Angiography CCTA. Lipoproteina is a protein carrying cholesterol and is linked to higher heart disease risk. Participants are randomly assigned to receive either lepodisiran or a placebo through subcutaneous injections. The study lasts about 120 weeks, with primary evaluation of changes in noncalcified plaque volume at baseline and at week 104. Secondary measures include changes in fat attenuation index scores, Lpa levels over time, participant feedback on drug administration, and pharmacokinetic analysis. Throughout the study, participants will undergo imaging assessments, blood tests to monitor Lpa levels, and questionnaires regarding treatment experience. The main outcome is the percent change in noncalcified plaque volume in heart vessels. The study includes safety monitoring and continues follow-up to assess effects comprehensively over the study period.
