Overview

Evolocumab is a monoclonal antibody designed for the treatment of hyperlipidemia by Amgen. It is a subcutaneous injection approved by the FDA for individuals on maximum statin therapy who still require additional LDL-cholesterol lowering. It is approved for both homozygous and heterozygous familial cholesterolemia as an adjunct to other first-line therapies. Evolocumab is a human IgG2 monoclonal antibody that targets the proprotein convertase subtilisin/kexin type 9 (PCSK9). PCSK9 is a protein that targets LDL receptors for degradation, therefore reducing the liver's ability to remove LDL-cholesterol (LDL-C), or "bad" cholesterol, from the blood. Evolocumab is designed to bind to PCSK9 and inhibit PCSK9 from binding to LDL receptors on the liver surface, resulting in more LDL receptors on the surface of the liver to remove LDL-C from the blood. Evolocumab is the second PCSK9 inhibitor on the market, first being alirocumab.

Indication

Evolocumab is indicated in adult patients with established cardiovascular disease to reduce the risk of myocardial infarction, stroke, and coronary revascularization. It is also indicated as an adjunct to diet, alone or in combination with other hypolipidemic treatments, in adults with primary hyperlipidemia (and in pediatric patients ≥10 years old with heterozygous familial hypercholesterolemia) to reduce LDL-C. In addition, it is indicated adjunctly to other hypolipidemic treatments in patients ≥10 years old with homozygous familiar hypercholesterolemia to reduce LDL-C.

Associated Conditions

  • Coronary Revascularization
  • Myocardial Infarction
  • Stroke
  • Increases in serum total low-density lipoprotein (LDL)

Evolocumab (Repatha®): A Comprehensive Monograph on a PCSK9 Inhibitor for Cardiovascular Risk Reduction

Executive Summary

Evolocumab represents a significant advancement in lipid-lowering therapy, embodying the successful translation of genetic discovery into a targeted biologic agent for cardiovascular risk reduction. As a fully human immunoglobulin G2 (IgG2) monoclonal antibody, evolocumab functions by selectively inhibiting proprotein convertase subtilisin/kexin type 9 (PCSK9), a key regulator of low-density lipoprotein receptor (LDLR) metabolism. By preventing PCSK9-mediated degradation of LDLRs, evolocumab enhances the liver's capacity to clear low-density lipoprotein cholesterol (LDL-C) from circulation, resulting in profound and sustained reductions in plasma LDL-C levels.

The clinical development of evolocumab, under the comprehensive PROFICIO program, has furnished a robust body of evidence supporting its efficacy and safety across a wide spectrum of patient populations. The landmark cardiovascular outcomes trial, FOURIER, demonstrated that the addition of evolocumab to statin therapy in patients with established atherosclerotic cardiovascular disease (ASCVD) significantly reduces the risk of major adverse cardiovascular events (MACE), including myocardial infarction, stroke, and coronary revascularization. This benefit was shown to accrue over time, a finding reinforced by long-term open-label extension studies. Furthermore, pivotal trials have established its efficacy in patients with heterozygous and homozygous familial hypercholesterolemia (HeFH and HoFH), including pediatric populations, as well as in patients with statin intolerance.
