Sanofi and Regeneron Present Positive Phase 3 Investigational Data for Praluent® (alirocumab) Injection in Patients Undergoing LDL Apheresis Therapy at ESC Congress 2016

- ODYSSEY ESCAPE data concurrently published in the European Heart Journal -

Paris, France and Tarrytown, New York - August 29, 2016-Sanofi and Regeneron Pharmaceuticals, Inc. today announced detailed positive results from ODYSSEY ESCAPE, a Phase 3 trial which evaluated Praluent® (alirocumab) Injection in patients with an inherited form of high cholesterol known as heterozygous familial hypercholesterolemia (HeFH) who require regular weekly or bi-weekly apheresis treatment. The trial demonstrated that adding Praluent to existing therapy reduced LDL cholesterol by approximately 50 percent from baseline (compared to 2 percent increase for placebo). Praluent significantly reduced the need for apheresis treatment by 75 percent compared to placebo (p<0.0001), the primary endpoint of the study. Results will be presented today at a Hot Line session at the ESC Congress 2016 in Rome, Italy.

Apheresis is a procedure similar to kidney dialysis where bad (LDL) cholesterol is removed from the blood, and is usually reserved for high-risk patients with very high cholesterol unable to achieve their cholesterol-lowering goals on any other therapy. Despite being treated with apheresis and entering ODYSSEY ESCAPE with very high LDL cholesterol levels (4.7 millimoles/liter [mmol/L] or 181 milligrams/deciliter [mg/dL]), nearly two-thirds (63 percent) of patients treated with Praluent no longer required apheresis therapy after six weeks of receiving Praluent. At this same time point, the average LDL cholesterol level among the Praluent-treated group was 2.3 mmol/L (90 mg/dL), compared to 4.8 mmol/L (185 mg/dL) in the placebo group. European guidelines recommend LDL cholesterol target levels between 1.8-3.0 mmol/L (70-115 mg/dL), depending on cardiovascular risk.

"Findings from ODYSSEY ESCAPE suggest a role for Praluent in the overall management of patients with HeFH undergoing regular apheresis therapy, with the potential to reduce the need for burdensome apheresis treatments," said Patrick M Moriarty, MD, Professor, Department of Internal Medicine; Director, Atherosclerosis and Lipoprotein Apheresis Center, University of Kansas Medical Center, United States. "This is a significant development in the continued investigation of this drug in HeFH patients, because it is the first clinical trial to demonstrate that Praluent reduced the frequency of apheresis therapy."

Apheresis therapy is an invasive, time-consuming and expensive treatment for some of the most difficult-to-treat patients. Treatment may cost up to $100,000 for each patient per year in the U.S. or up to €60,000 in Germany, where there are 200 centers and LDL apheresis is more frequently used. In the U.S. there are only approximately 60 apheresis centers and many patients must travel significant distances for the procedure.

Other key results from ODYSSEY ESCAPE, which will be concurrently published in the European Heart Journal, include:

  • Ninety-three percent of patients treated with Praluent experienced at least a 50 percent reduction in their apheresis procedures (p>0.0001).
  • Throughout the trial, patients treated with Praluent experienced significant reductions in their LDL cholesterol starting at week 6 (55 percent greater reduction compared to placebo), and lasting until the trial ended, at week 18 (46 percent greater reduction compared to placebo) (p<0.0001).
  • A similar proportion of patients experienced adverse events (AEs) in both the Praluent and placebo groups (76 percent both groups). The most common AEs (occurring in at least 5 percent of the Praluent group) were: fatigue (15 percent Praluent; 10 percent placebo), nasopharyngitis (10 percent Praluent; 10 percent placebo), diarrhea (10 percent Praluent; 0 percent placebo), myalgia (10 percent Praluent; 5 percent placebo), upper respiratory infection (7 percent Praluent; 19 percent placebo), headache (7 percent Praluent; 5 percent placebo), arthralgia (7 percent Praluent; 10 percent placebo), and back pain (5 percent Praluent; 10 percent placebo).

The completed Phase 3 placebo-controlled ODYSSEY ESCAPE trial involved 62 patients from 14 treatment centers in the U.S. and Germany. These patients were receiving regular baseline apheresis therapy at fixed intervals of every week or every 2 weeks prior to randomization. Average LDL cholesterol at baseline was 4.7 mmol/L (181 mg/dL). Eighty-six percent (placebo group) and 90 percent (Praluent group) of patients had a history of coronary heart disease.

Patients were randomized to receive Praluent 150 mg (n=41) subcutaneously every 2 weeks or placebo (n=21), in addition to their existing treatment regimen. The double-blind treatment period comprised two intervals: for the first 6 weeks, patients remained on their established apheresis schedule at baseline, and for the following 12 weeks, apheresis frequency was adjusted based on the patient's LDL cholesterol response to treatment. ODYSSEY ESCAPE is part of the overarching Phase 3 ODYSSEY program, which includes more than 25,000 patients.

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, which results in lower LDL cholesterol levels in the blood. Praluent is the only PCSK9 inhibitor available in two dosages with two levels of efficacy (75 mg and 150 mg), allowing physicians to select dose based on a patient's LDL cholesterol lowering needs.

Praluent is approved in approximately 40 countries worldwide, including the U.S., Japan, Canada, Switzerland, Mexico, Brazil and the European Union (EU). In the U.S., Praluent is approved for use as adjunct to diet and maximally tolerated statin therapy for the treatment of adults with HeFH or clinical atherosclerotic CV disease, who require additional lowering of LDL cholesterol. In the E.U., Praluent is approved for the treatment of adult patients with primary hypercholesterolemia (HeFH and non-familial) or mixed dyslipidemia as an adjunct to diet: a) in combination with a statin, or statin with other lipid-lowering therapies in patients unable to reach their LDL cholesterol goals with the maximally-tolerated statin or b) alone or in combination with other lipid-lowering therapies for patients who are statin intolerant, or for whom a statin is contraindicated. The effect of Praluent on CV morbidity and mortality has not yet been determined. ODYSSEY OUTCOMES is prospectively evaluating the effect of Praluent on the occurrence of CV events in approximately 18,000 patients who have experienced an acute coronary syndrome.
