Introduction: Twice-yearly inclisiran (after the initial and 3-month doses) provides effective and sustained low-density lipoprotein cholesterol (LDL-C) reduction in individuals with hyperlipidemia with a favorable long-term safety profile. Limited studies have assessed the impact of inclisiran on the quality of life (QoL) of patients with atherosclerotic cardiovascular disease (ASCVD) or ASCVD-risk equivalent. The VICTORION-Difference study will evaluate the early efficacy, safety, and QoL outcomes with inclisiran compared to placebo on top of individually optimized lipid-lowering therapy.
Methods and analysis: This phase 4, randomized, double-blind, placebo-controlled trial includes participants aged ≥18 years with hypercholesterolemia at high or very high cardiovascular (CV) risk despite being treated with an individualized maximally tolerated statin dose. Participants are randomized 1:1 to receive either subcutaneous injections of 300-mg inclisiran sodium (equivalent to 284-mg inclisiran) or placebo. In addition to the treatment with inclisiran/placebo, open-label rosuvastatin (starting dose of 5 mg/day or 10 mg/day) is sequentially and optimally titrated to the maximally tolerated dose, if the individual LDL-C goals are not achieved. The primary objective is to assess the achievement of LDL-C goals at day 90. Secondary objectives include the assessment of muscle-related adverse events, pain-related QoL scores, and mean LDL-C reduction.
Ethics and dissemination: The results of the study will be disseminated through peer-reviewed journals, conference presentations, and other scientific forums to inform clinical practice and future research in the field of hypercholesterolemia and CV disease management.
