Lp(a) biology and the full emerging-therapy pipeline, review spanning ASOs to CRISPR and obicetrapib (Cardiovasc Drugs Ther 2026)

Purpose: Lipoprotein(a) [Lp(a)] is increasingly recognized as a genetically determined, independent risk factor for atherosclerotic cardiovascular disease (ASCVD). This review examines the structure, pathophysiology, and epidemiology of Lp(a), with a focus on its contribution to ASCVD and related conditions such as aortic valve stenosis and peripheral artery disease. The main research question addresses how Lp(a) influences cardiovascular risk and how emerging therapies may modify this risk.

Methods: This review synthesizes published evidence describing the biological characteristics of Lp(a), its mechanistic roles in disease, and its epidemiologic associations with cardiovascular outcomes. It also evaluates current and investigational therapeutic approaches by examining clinical trial data for agents targeting Lp(a).

Results: Lp(a) contributes to residual cardiovascular risk through proatherogenic, proinflammatory, and prothrombotic mechanisms. Current evidence highlights its involvement in ASCVD, aortic valve stenosis, and peripheral artery disease. Clinical studies of antisense oligonucleotides, small interfering RNAs, oral small molecules, and CRISPR-based gene editing, including pelacarsen, olpasiran, zerlasiran, lepodisiran, muvalaplin, and obicetrapib, demonstrate promising efficacy and safety. These agents show potential to significantly reduce Lp(a) levels and influence future cardiovascular prevention strategies.

Conclusion: As novel therapies advance and clinical guidelines evolve, Lp(a) is emerging as a central determinant in personalized cardiovascular care. The increasing emphasis on Lp(a) testing underscores its importance in risk stratification and future therapeutic decisionmaking.
