Evinacumab, sold under the brand name Evkeeza, is a medication used to treat homozygous familial hypercholesterolemia (HoFH).[1] It is used in those who are at least 12 years old; however, effects on heart disease and life expectancy is unclear as of 2022.[1] It is given by injection into a vein.[1]

Common side effects include the influenza-like illness, dizziness, runny nose, and nausea.[1] Other side effects may include anaphylaxis.[1] Use in pregnancy may harm the baby.[1] It is a monoclonal antibody that binds to and blocks angiopoietin-like protein 3 (ANGPTL3), resulting in faster break down of fats.[1][2]

Evinacumab was approved for medical use in the United States and Europe in 2021.[1][2] In the United States it costs about 450,000 USD per year as of 2022.[4]

Medical uses

Over 24 weeks, in those with homozygous familial hypercholesterolemia (HoFH), it reduced LDL cholesterol levels by almost half compared to about 2% seen with a placebo.[2]


It is given at a dose of 15 mg/kg every 4 weeks.[1]

Mechanism of action

Evinacumab—mechanism of action[5]

In terms of the mechanism of action of Evinacumab we find that it works via inhibiting ANGPTL3 which in turn reduces LDL-C and triglycerides levels. Hence effective against familial hypercholesterolemia.[5]


The effectiveness and safety of evinacumab were evaluated in a double-blind, randomized, placebo-controlled, 24-week trial enrolling 65 participants with homozygous familial hypercholesterolemia (HoFH).[3] In the trial, 43 participants received 15 mg/kg of evinacumab every four weeks and 22 participants received the placebo.[3] Participants were taking other lipid-lowering therapies as well.[3]

The primary measure of effectiveness was the percent change in low-density lipoprotein (LDL-C) from the beginning of treatment to week 24.[3] At week 24, participants receiving evinacumab had an average 47% decrease in LDL-C while participants on the placebo had an average 2% increase.[3]

The U.S. Food and Drug Administration (FDA) granted the application for evinacumab orphan drug, breakthrough therapy, and priority review designations.[3] The FDA granted approval of Evkeeza to Regeneron Pharmaceuticals, Inc.[3] Regeneron invented evinacumab using the company's genetically-engineered mouse platform endowed with a genetically-humanized immune system to produce fully-human monoclonal antibodies.[6]

Legal status

On 22 April 2021, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a marketing authorization under exceptional circumstances for the medicinal product Evkeeza, intended for the treatment of adult and adolescent patients aged 12 years and older with homozygous familial hypercholesterolaemia (HoFH).[7] The applicant for this medicinal product is Regeneron Ireland Designated Activity Company (DAC).[7] Evinacumab was approved for medical use in the European Union in June 2021.[2]
