Common side effects include nasopharyngitis (cold), influenza-like illness, dizziness, rhinorrhea (runny nose), and nausea. Serious hypersensitivity (allergic) reactions have occurred in the Evkeeza clinical trials.[2]

Evinacumab binds to the angiopoietin-like protein 3 (ANGPTL3).[2] ANGPTL3 slows the function of certain enzymes that break down fats in the body.[2] Evinacumab blocks ANGPTL3, allowing faster break down of fats that lead to high cholesterol.[2] Evinacumab was approved for medical use in the United States in February 2021.[2][4][5]

Regeneron invented evinacumab using the company's VelocImmune® technology, a proprietary genetically-engineered mouse platform endowed with a genetically-humanized immune system to produce optimized fully-human monoclonal antibodies.[6]

History

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).[2] In the trial, 43 participants received 15 mg/kg of evinacumab every four weeks and 22 participants received the placebo.[2] Participants were taking other lipid-lowering therapies as well.[2]

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

The U.S. Food and Drug Administration (FDA) granted the application for evinacumab orphan drug, breakthrough therapy, and priority review designations.[2] The FDA granted approval of Evkeeza to Regeneron Pharmaceuticals, Inc.[2]

Society and culture

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.[3]
