FDA approval extends the indication of Evkeeza to treat younger patients with homozygous hypercholesterolemia (HoFH) HoFH is an inherited condition characterized by extremely high levels of low-density lipoprotein cholesterol (LDL-C) Initial Evkeeza approval based on placebo-controlled trial showing Evkeeza, when added to standard lipid-lowering therapies, could lower LDL-C by about 50% compared to placebo in this high unmet need population TARRYTOWN, N.Y., Sept. 26, 2025 (GLOBE NEWSWIRE) -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced that the U.S. Food and Drug Administration (FDA) has approved Evkeeza® (evinacumab-dgnb) ANGPTL3 antibody as an adjunct to diet and exercise and other lipid-lowering therapies for the treatment of children from age 1 to less than 5 years old with homozygous familial hypercholesterolemia (HoFH). Evkeeza was initially approved in 2021 for adults and adolescents aged 12 years and older with HoFH based on a placebo-controlled trial showing Evkeeza, when added to standard lipid-lowering therapies, could lower LDL-C by about 50% compared to placebo in this high unmet need population. It was then approved for children aged 5 to 11 in 2023. All Evkeeza FDA submissions were evaluated under Priority Review, which is reserved for medicines that represent potentially significant improvements in efficacy or safety in treating serious conditions. HoFH is the most severe form of familial hypercholesterolemia (FH), and affects approximately 1,300 people in the U.S. It occurs when two copies of the FH-causing genes are inherited, one from each parent, resulting in dangerously high levels (usually >400 mg/dL) of low-density lipoprotein cholesterol (LDL-C). Those living with HoFH are at risk for premature atherosclerotic disease and cardiac events even in their teenage years. Many patients are not diagnosed or are only diagnosed later in life. “The approval of Evkeeza for children as young as 1 year of age addresses a critical unmet need for those with homozygous familial hypercholesterolemia, a life-threatening condition that causes extraordinarily high LDL-C levels from birth,” said Katherine Wilemon, Founder and CEO of the Family Heart Foundation. “Families and their medical teams will now have an effective treatment option for these very young children who are at risk of serious complications from diseased arteries and calcified valves without timely and sufficient LDL-C lowering. This development underscores the importance of, and urgency needed in, identifying children with FH through pediatric screenings in accordance with guidelines.” The extended indication for Evkeeza was supported by clinical efficacy and safety data among 6 children living with HoFH (including pharmacokinetic data among 4 of these patients) who took part in either the U.S. expanded access program or ex-U.S. compassionate use program for Evkeeza. No new safety concerns have been identified in the compassionate use program. The most common adverse reactions (≥5%) of Evkeeza include nasopharyngitis, influenza-like illness, dizziness, rhinorrhea, nausea, and fatigue. “Evkeeza is a testament to the power of Regeneron’s science and proprietary technologies in developing first-in-class, lifechanging medicines that become standard-of-care,” said George D. Yancopoulos, M.D., Ph.D., Board co-Chair, President and Chief Scientific Officer at Regeneron. “This label extension adds to our growing commitment to the rare disease space, which includes diverse clinical development programs in neuromuscular and genetic diseases – such as myasthenia gravis, otoferlin hearing loss, and fibrodysplasia ossificans progressiva – for which we’ve shared data.” Regeneron is committed to helping patients who have been prescribed Evkeeza access their medication through its myRARE® patient support program. myRARE offers financial assistance to eligible patients, as well as resources to help patients and healthcare providers get started with Evkeeza including product information, insurance benefit verification, community connections, and appointment reminders.

Regeneron scientists discovered the angiopoietin gene family more than two decades ago. Human genetics research published in New England Journal of Medicine in 2017 by scientists from the Regeneron Genetics Center® found that patients whose ANGPTL3 gene did not function properly (called a “loss-of function mutation”) have significantly lower levels of key blood lipids, including LDL-C, and that this is associated with a significantly lower risk of coronary artery disease. The generic name for Evkeeza in its approved U.S. indications is evinacumab-dgnb, with dgnb the suffix designated in accordance with Nonproprietary Naming of Biological Products Guidance for Industry issued by the U.S. FDA. Regeneron is responsible for the development and distribution of Evkeeza in the U.S. and is collaborating with Ultragenyx to clinically develop, commercialize and distribute Evkeeza outside of the U.S. About Regeneron’s VelocImmune Technology Regeneron's VelocImmune technology utilizes a proprietary genetically engineered mouse platform endowed with a genetically humanized immune system to produce optimized fully human antibodies. When Regeneron's co-Founder, President and Chief Scientific Officer George D. Yancopoulos was a graduate student with his mentor Frederick W. Alt in 1985, they were the first to envision making such a genetically humanized mouse, and Regeneron has spent decades inventing and developing VelocImmune and related VelociSuite® technologies. Dr. Yancopoulos and his team have used VelocImmune technology to create a substantial proportion of all original, FDA-approved fully human monoclonal antibodies. This includes Dupixent® (dupilumab), Libtayo® (cemiplimab-rwlc), Praluent® (alirocumab), Kevzara® (sarilumab), Evkeeza® (evinacumab-dgnb), Inmazeb® (atoltivimab, maftivimab and odesivimab-ebgn) and Veopoz® (pozelimab-bbfg). In addition, REGEN-COV® (casirivimab and imdevimab) had been authorized by the FDA during the COVID-19 pandemic until 2024. U.S. INDICATION EVKEEZA is an injectable prescription medicine used along with diet and exercise and other low-density lipoprotein-cholesterol (LDL-C) lowering medicines to lower LDL-C in adults and children 1 year of age and older with a type of high cholesterol called homozygous familial hypercholesterolemia (HoFH). It is not known if EVKEEZA is safe and effective in children under 1 year of age.
