Lipid-Lowering RNA Therapeutics for Atherosclerotic Cardiovascular Disease Prevention: A State-of-the-Art Review.

Abstract

Despite the modern era of effective and safe high-intensity statins and non-statin agents, a significant portion of patients are still unable to achieve guideline-recommended lipid goals for the prevention of atherosclerotic cardiovascular disease (ASCVD) events. Accordingly, novel strategies are needed to further mitigate residual risk for patients on the background of maximally tolerated lipid-lowering therapies. The past decade has seen an explosion of new agents leveraging ribonucleic acid (RNA)-based technology which reduce plasma lipoprotein levels. In this state-of-the-art review, we examine the ongoing clinical development of lipid-lowering RNA therapeutics. We discuss the efficacy and safety profiles of antisense oligonucleotides and small interfering RNA agents targeting low-density lipoprotein, lipoprotein(a), and triglyceride-rich lipoproteins. We also present challenges future clinical trials must answer to prove RNA therapeutics as a viable strategy for ASCVD prevention among patients with refractory hyperlipidemia.
