Evolocumab: A Review in Hyperlipidemia.

Evolocumab (Repatha(®)) is a monoclonal antibody targeting proprotein convertase subtilisin/kexin type 9 (PCSK9) that is administered subcutaneously at a dosage of 140 mg every 2 weeks or 420 mg once monthly. Across 12-week phase III trials in patients with primary hypercholesterolemia or mixed dyslipidemia, evolocumab was more effective than placebo (treatment difference -54.8 to -76.3%) and/or ezetimibe (treatment difference -36.9 to -47.2%) at reducing low-density lipoprotein cholesterol (LDL-C) levels, including when added to statin therapy, when administered to statin-intolerant patients, when administered as monotherapy, and in patients with heterozygous familial hypercholesterolemia who were receiving statins with or without other lipid-lowering drugs. Evolocumab also significantly lowered LDL-C levels (treatment difference of ≈30% vs. placebo) in patients with homozygous familial hypercholesterolemia when added to statins with or without ezetimibe in a 12-week phase III trial. The efficacy of evolocumab was maintained in the longer term, and it was well tolerated. In conclusion, subcutaneous evolocumab is a valuable new treatment for use in primary hypercholesterolemia or mixed dyslipidemia and homozygous familial hypercholesterolemia, particularly in patients unable to reach LDL-C goals despite treatment with statins with or without other lipid-lowering therapies and in patients who do not tolerate or are not able to receive statins.
