FDA to Review Supplemental Biologics License Application for Praluent® (alirocumab)Injection as Potential Treatment to Reduce Major Adverse Cardiovascular Events

TARRYTOWN, N.Y. and PARIS, Sept. 12, 2018 /PRNewswire/ -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) and Sanofi announced that the U.S. Food and Drug Administration (FDA) has accepted a supplemental Biologics License Application (sBLA) for Praluent^® (alirocumab) Injection, a PCSK9 inhibitor. The sBLA outlines a proposed update to the Prescribing Information to include the effect of Praluent in reducing the overall risk of major adverse cardiovascular events (MACE). MACE is an umbrella term that includes heart attack, ischemic stroke, death from coronary heart disease and unstable angina requiring hospitalization. The FDA set a Prescription Drug User Fee Act (PDUFA) action date of April 28, 2019.

The sBLA is supported by data from ODYSSEY OUTCOMES, a Phase 3 cardiovascular outcomes trial that assessed the effect of Praluent in 18,924 patients who had an acute coronary syndrome (ACS), such as a heart attack, between 1-12 months (median 2.6 months) before enrolling in the trial. Results of the ODYSSEY OUTCOMES trial were presented at the American College of Cardiology's 67^th Annual Scientific Session & Expo in March 2018.

The effect of Praluent on cardiovascular morbidity and mortality, including MACE, is currently being reviewed and has not been fully evaluated by any regulatory authority.

In addition, the FDA recently approved an update to the Praluent Prescribing Information to include clinical information regarding its use in patients with heterozygous familial hypercholesterolemia (HeFH) who require additional lowering of LDL-C along with diet and maximally-tolerated statin therapy and who are undergoing apheresis treatment. Apheresis is a procedure where LDL-C is removed from the blood, in a process similar to kidney dialysis. The recommended dose of Praluent in patients undergoing LDL apheresis is 150 mg once every 2 weeks. Praluent can be administered without regard to timing of apheresis.

The update is supported by data from the pivotal Phase 3 ODYSSEY ESCAPE trial of 62 patients with HeFH, an inherited form of high cholesterol, whose cholesterol levels required chronic, weekly or bi-weekly apheresis therapy.

About Praluent
Praluent inhibits the binding of PCSK9 (proprotein convertase subtilisin/kexin type 9) 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 is being developed by Regeneron and Sanofi under a global collaboration agreement and was invented by Regeneron using the company's proprietary VelocImmune^® technology that yields optimized fully-human monoclonal antibodies.

Praluent is approved in more than 60 countries worldwide, including the U.S., Japan, Canada, Switzerland, Mexico and Brazil, as well as the European Union (EU). In the U.S., Praluent is approved for use as an adjunct to diet and maximally tolerated statin therapy for the treatment of adults with HeFH or clinical atherosclerotic cardiovascular disease (ASCVD) who require additional lowering of LDL-C. The effect of Praluent on cardiovascular morbidity and mortality has not been determined.

Important Safety Information for the U.S.
Do not use Praluent if you are allergic to alirocumab or to any of the ingredients in Praluent.

Before you start using Praluent, tell your healthcare provider about all your medical conditions, including allergies, and if you are pregnant or plan to become pregnant or if you are breastfeeding or plan to breastfeed.

Tell your healthcare provider or pharmacist about any prescription and over-the-counter medicines you are taking or plan to take, including natural or herbal remedies.

Call your healthcare provider or go to the nearest hospital emergency room right away if you have any symptoms of an allergic reaction including a severe rash, redness, severe itching, a swollen face, or trouble breathing.

The most common side effects of Praluent include: redness, itching, swelling, or pain/tenderness at the injection site, symptoms of the common cold, and flu or flu-like symptoms. Tell your healthcare provider if you have any side effect that bothers you or that does not go away.
