Tafolecimab, a Third Monoclonal Antibody for PCSK9 as the Novel Lipid-Lowering Drug Around the World: A Narrative Review.

Abstract

Tafolecimab, a fully human monoclonal antibody targeting proprotein convertase subtilisin/kexin type 9 (PCSK9), represents a significant therapeutic advancement in the management of hypercholesterolemia and has been approved for use in the Chinese population. Elevated low-density lipoprotein cholesterol (LDL-C) is a major risk factor for atherosclerotic cardiovascular disease, and traditional treatments often fall short due to challenges such as statin intolerance. Clinical trials have demonstrated that tafolecimab can effectively reduce LDL-C levels, achieving reductions of over 60% in many patients. It also improves other lipid parameters, including lipoprotein(a) [Lp(a)], non-high-density lipoprotein cholesterol (non-HDL-C), and apolipoprotein B (ApoB). It has a favorable safety profile, primarily characterized by mild to moderate adverse events. The long-acting formulation of tafolecimab enables less frequent dosing, thereby promoting compliance. As cardiovascular diseases continue to escalate globally, tafolecimab holds promise not only for patients in China but also for broader international applications, representing a critical advancement in the evolving landscape of lipid-lowering therapies.
