Usefulness of alirocumab and evolocumab for the treatment of patients with diabetic dyslipidemia.

In 2015, the US Food and Drug Administration (FDA) approved the anti-proprotein convertase subtilsin/kexin type 9 (PCSK9) monoclonal antibodies, alirocumab and evolocumab, to treat patients with hypercholesterolemia and mixed dyslipidemia. Since then, considerable attention has been paid to the use of these monoclonal antibodies for the treatment of diabetic dyslipidemia with a goal of reducing the risk for cardiovascular disease. Recently, consensus statements on the clinical use of PCSK9 inhibitors in patients with type 2 diabetes mellitus, who are unable to achieve the goal of low-density lipoprotein cholesterol (<70 mg/dL or <1.8 mmol/L), have been published by panels of experts in Greece, Europe (European Society of Cardiology and European Atherosclerosis Society Task Force), and the United States (American College of Cardiology Consensus Committee). On December 1, 2017, the FDA approved evolocumab to prevent heart attack, stroke, and coronary revascularization. In this article, we review recent advances concerning the pathophysiology of diabetic dyslipidemia, the physiology of PCSK9, the mechanisms of action of PCSK9 inhibitors, clinical trials examining PCSK9 inhibitors in type 2 diabetes, and perspectives of nonstatin therapy in the treatment of diabetic dyslipidemia.
