PCSK9 inhibitors and managing cost in the managed care setting

In patients with hypercholesterolemia who have atherosclerotic cardiovascular disease and/or familial hypercholesterolemia, a new class of drugs may be helpful in reducing serum levels of low-density lipoprotein cholesterol (LDL-C) beyond maximally tolerated statin therapy. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors lower LDL-C through a different mechanism of action than standard cholesterol-lowering therapies. Currently approved PCSK9 inhibitors are the monoclonal antibodies alirocumab and evolocumab. Although the drugs produce substantial reductions in LDL-C, cost issues and efficacy in preventing cardiovascular events should be evaluated when considering the adoption of PCSK9 inhibitors in the managed care setting.
