PCSK9 Monoclonal Antibodies Have Come a Long Way.

PURPOSE OF THE REVIEW

This review examines the pivotal role of monoclonal antibodies against PCSK9 in lipid-lowering therapy, emphasizing their biological and clinical impact.

RECENT FINDINGS

Randomized controlled trials have validated that PCSK9 monoclonal antibodies (Mabs) effectively reduce LDL-c levels by approximately 50%, even when added to maximal statin therapy. They moreover produce a notable 15-20% relative decrease in major cardiovascular events, with a greater reduction among high-risk patients and no evidence for serious adverse effects, assuaging previous concerns. This review highlights the benefits of PCSK9 Mabs in high cardiovascular risk patients. Despite their efficacy and safety, these therapies are hindered by limited access, and require broader integration into clinical practice to optimize therapeutic outcomes.
