ABSTRACT
Despite advances in therapies that target low-density lipoprotein (LDL), atherosclerotic cardiovascular disease (ASCVD) remains a major cause of morbidity and mortality. This has led to the investigation of other biomarkers, including lipoprotein(a) [Lp(a)]. Lp(a) is a variant of LDL that is genetically determined, has proatherogenic, proinflammatory, and prothrombotic effects, and has a linear correlation with ASCVD risk. Approximately 20%-30% of the global population has elevated serum Lp(a). Recommendations for increased Lp(a) testing has heightened the need for effective medications to target this biomarker. Although traditional antilipemic agents have demonstrated negligible effects on Lp(a), multiple targeted therapies are emerging, including antisense oligonucleotides, small interfering RNA agents, and small molecules. The efficacy of these novel agents observed in early clinical trials and the development of alternate treatment modalities, including gene editing and RNA-based innovations, signal a promising new era of ASCVD prevention via non-LDL pathways. SIGNIFICANCE STATEMENT: Lipoprotein(a) is a genetically determined biomarker that significantly impacts atherosclerotic risk. The development of novel therapies that lower lipoprotein(a) warrants a broad understanding to increase comfortability and optimize utilization upon market approval.
