Approval extends treatment of Praluent to children aged 8 and older with heterozygous familial hypercholesterolemia (HeFH)
TARRYTOWN, N.Y., March 11, 2024 (GLOBE NEWSWIRE) -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) announced the U.S. Food & Drug Administration (FDA) has extended the approval of Praluent® (alirocumab) as an adjunct to diet and other low-density lipoprotein cholesterol (LDL-C) lowering therapies to include pediatric patients aged 8 and older with heterozygous familial hypercholesterolemia (HeFH).
“Many children with heterozygous familial hypercholesterolemia (HeFH) are able to substantially improve their LDL-C (bad cholesterol) with currently available therapies. But for those children whose LDL-C remains dangerously high, this approval is an important milestone as it gives these children and their families an additional option to help reduce and manage their LDL-C levels much earlier in their lives,” said Mary P. McGowan, M.D., Chief Medical Officer of the Family Heart Foundation.
Familial hypercholesterolemia (FH) is an inherited condition caused by mutations in one of several genes that control how the body processes cholesterol, which can lead to very high levels of LDL-C (bad cholesterol). FH can come in two forms: HeFH, which develops when one mutated gene is inherited from one parent; and homozygous familial hypercholesterolemia (HoFH), which develops when a mutated gene is inherited from both parents. Praluent is approved to treat both children and adults with HeFH and adults with HoFH.
The approval is based on a Phase 3, randomized multicenter trial evaluating pediatric patients aged 8 to 17 with HeFH, who had LDL-C levels of 130mg/dL or greater and were already being treated with lipid-lowering medications. Patients were randomized to receive Praluent (N=101) or placebo (N=52) every two or four weeks in two consecutive cohorts. Patients who received Praluent every four weeks had 31% lower LDL-C than placebo at 24 weeks (97.5% Confidence Interval: -45.0% to -17.9%; p<0.0001). Improvements in additional key lipid parameters were also observed. Results from the trial were recently published in the Journal of the American Medical Association Pediatrics.
No new adverse reactions were identified in this trial, and the safety pro consistent with the safety pro in adults with HeFH. Across Praluent trials in patients with primary hyperlipidemia (N=2,476), the most common adverse reactions (≥5%) more frequently observed with Praluent than placebo have been injection site reactions (7%), and influenza (6%) and diarrhea (5%).
“The approval of Praluent for the treatment of high cholesterol was a historic landmark achievement, as it was the first approved therapy targeting the genetically-validated PCSK9 target for heart disease,” said George D. Yancopoulos, M.D., Ph.D., Board co-Chair, President and Chief Scientific Officer at Regeneron, and a principal inventor of Praluent. “Praluent has made a meaningful impact in the treatment of adults with familial hypercholesterolemia, and we are proud that our innovation will now be able to help appropriate children with the heterozygous form of this disease manage their dangerously high levels of LDL-C.”
About the Praluent HeFH Pediatric Trial
The randomized multicenter Phase 3 trial consisted of a 24-week double-blind, placebo-controlled evaluating the efficacy and safety of Praluent in pediatric patients aged 8 to 17 years with HeFH (N=79). The primary endpoint was the percent change in LDL-C from baseline to week 24 in the Praluent and placebo treated patients. At baseline, patients were on a low-fat diet and being treated with background lipid-lowering therapy. In the trial, patients were randomized 2:1 to receive Praluent or placebo every 2 or 4 weeks. The Praluent dose was based on body weight.
About Praluent
Praluent inhibits the binding of PCSK9 to the LDL receptor and thereby increases the number of available LDL receptors on the surface of liver cells to clear LDL, which lowers LDL-C levels in the blood. Praluent was developed by Regeneron and Sanofi under a global collaboration agreement and invented by Regeneron using the company's proprietary VelocImmune® technology that yields optimized fully-human monoclonal antibodies.
In the U.S., Praluent is currently indicated:
to reduce the risk of myocardial infarction, stroke, and unstable angina requiring hospitalization in adults with established cardiovascular disease
as an adjunct to diet, alone or in combination with other low-density lipoprotein cholesterol (LDL-C) lowering therapies in adults with primary hyperlipidemia including HeFH to reduce LDL-C
as an adjunct to other LDL-C-lowering therapies in adults with HoFH to reduce LDL-C
along with diet and other LDL-C lowering treatments in children aged 8 years and older with HeFH to reduce LDL-C
In addition to the U.S., Praluent is approved in 60 countries, including the European Union, Japan, Canada, Switzerland and Brazil.
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 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 currently available. This includes Evkeeza® (evinacumab-dgnb), REGEN-COV® (casirivimab and imdevimab), Dupixent® (dupilumab), Libtayo® (cemiplimab-rwlc), Praluent, Kevzara® (sarilumab), Inmazeb® (atoltivimab, maftivimab and odesivimab-ebgn) and Veopoz® (pozelimab-bbfg).
IMPORTANT SAFETY INFORMATION AND INDICATIONS
INDICATIONS
PRALUENT is an injectable prescription medicine used:
in adults with cardiovascular disease to reduce the risk of heart attack, stroke, and certain types of chest pain conditions (unstable angina) requiring hospitalization.
along with diet, alone or together with other cholesterol-lowering medicines in adults with high blood cholesterol levels called primary hyperlipidemia (including a type of high cholesterol called heterozygous familial hypercholesterolemia [HeFH]), to reduce low-density lipoprotein cholesterol (LDL-C) or bad cholesterol.
along with other LDL-lowering treatments in adults with a type of high cholesterol called homozygous familial hypercholesterolemia, who need additional lowering of LDL-C.
along with diet and other LDL-C lowering treatments in children aged 8 years and older with HeFH to reduce LDL-C.
It is not known if PRALUENT is safe and effective in children who are younger than 8 years of age or in children with other types of high cholesterol (hyperlipemias).
IMPORTANT SAFETY INFORMATION
