THOUSAND OAKS, Calif., Jan. 5, 2017 /PRNewswire/ -- Amgen (NASDAQ:AMGN) today announced that the United States District Court in Delaware granted Amgen's request for a permanent injunction prohibiting Sanofi and Regeneron from infringing two patents that Amgen holds for Repatha® (evolocumab) by manufacturing, using, selling or offering alirocumab for sale in the United States. The injunction will not take effect immediately as the court has delayed its imposition for 30 days to allow defendants the opportunity to seek expedited review of this decision. The judge's decision follows a jury verdict in March 2016 in Amgen's favor in a trial on the validity of two Amgen patents that describe and claim monoclonal antibodies to proprotein convertase subtilisin/kexin type 9 (PCSK9).
"We are pleased with today's decision that recognizes Amgen is entitled to an injunction against further infringement of our patent rights. Sanofi and Regeneron admitted that they had infringed our patents, and the jury upheld our patents as valid. Protecting intellectual property is essential to our industry as it reinforces the incentives for the large and risky investments we make in innovation to bring forward new medicines to treat serious diseases," said Robert A. Bradway, chairman and chief executive officer at Amgen. Bradway continued, "Heart disease is the biggest health care challenge for society today and Repatha aims to help address this challenge by providing a profound reduction in LDL-cholesterol."
Amgen has the ability to supply all potential Repatha patients and will work to ensure a smooth transition for patients who wish to switch to Repatha.
About Repatha® (evolocumab) Repatha® (evolocumab) is a human monoclonal antibody that inhibits proprotein convertase subtilisin/kexin type 9 (PCSK9). Repatha binds to PCSK9 and inhibits circulating PCSK9 from binding to the low-density lipoprotein (LDL) receptor (LDLR), preventing PCSK9-mediated LDLR degradation and permitting LDLR to recycle back to the liver cell surface. By inhibiting the binding of PCSK9 to LDLR, Repatha increases the number of LDLRs available to clear LDL from the blood, thereby lowering LDL-C levels.1
The FOURIER outcomes trial is designed to evaluate whether treatment with Repatha or placebo on top of optimized statin therapy, reduces the risk of cardiovascular events in patients with clinically evident atherosclerotic disease. The trial completed patient enrollment in June 2015. The primary endpoint for the FOURIER trial is major cardiovascular events defined as the composite of cardiovascular death, myocardial infarction (MI), stroke, hospitalization for unstable angina or coronary revascularization. The key secondary endpoint is the composite of cardiovascular death, MI or stroke. The trial is planned to continue until at least 1,630 patients experience the secondary endpoint, thereby providing 90 percent power to detect a relative reduction of 15 percent in this endpoint. Top-line results from the approximately 27,500-patient event-driven FOURIER study are anticipated in the first quarter of 2017.
Repatha is approved in more than 40 countries, including the U.S., Japan, Canada and in all 28 countries that are members of the European Union. Applications in other countries are pending.
Important U.S. Product Information
Repatha® is indicated as an adjunct to diet and:
Maximally tolerated statin therapy for treatment of adults with heterozygous familial hypercholesterolemia (HeFH) or clinical atherosclerotic cardiovascular disease (ASCVD), who require additional lowering of low-density lipoprotein cholesterol (LDL-C)
Other LDL-lowering therapies (e.g., statins, ezetimibe, LDL apheresis) in patients with homozygous familial hypercholesterolemia (HoFH) who require additional lowering of LDL-C
The effect of Repatha® on cardiovascular morbidity and mortality has not been determined.
The safety and effectiveness of Repatha® have not been established in pediatric patients with HoFH who are younger than 13 years old.
The safety and effectiveness of Repatha® have not been established in pediatric patients with primary hyperlipidemia or HeFH.
Important U.S. Safety Information
Contraindication: Repatha® is contraindicated in patients with a history of a serious hypersensitivity reaction to Repatha®.
Allergic reactions: Hypersensitivity reactions (e.g. rash, urticaria) have been reported in patients treated with Repatha®, including some that led to discontinuation of therapy. If signs or symptoms of serious allergic reactions occur, discontinue treatment with Repatha®, treat according to the standard of care, and monitor until signs and symptoms resolve.
Adverse reactions: The most common adverse reactions (>5% of Repatha® -treated patients and more common than placebo) were: nasopharyngitis, upper respiratory tract infection, influenza, back pain, and injection site reactions.
In a 52-week trial, adverse reactions led to discontinuation of treatment in 2.2% of Repatha® -treated patients and 1% of placebo-treated patients. The most common adverse reaction that led to Repatha® treatment discontinuation and occurred at a rate greater than placebo was myalgia (0.3% versus 0% for Repatha® and placebo, respectively).
Adverse reactions from a pool of the 52-week trial and seven 12-week trials: Local injection site reactions occurred in 3.2% and 3.0% of Repatha® -treated and placebo-treated patients, respectively. The most common injection site reactions were erythema, pain, and bruising. The proportions of patients who discontinued treatment due to local injection site reactions in Repatha® -treated patients and placebo-treated patients were 0.1% and 0%, respectively.
Allergic reactions occurred in 5.1% and 4.7% of Repatha® -treated and placebo-treated patients, respectively. The most common allergic reactions were rash (1.0% versus 0.5% for Repatha® and placebo, respectively), eczema (0.4% versus 0.2%), erythema (0.4% versus 0.2%), and urticaria (0.4% versus 0.1%).
Neurocognitive events were reported in less than or equal to 0.2% in Repatha®-treated and placebo-treated patients.
In a pool of placebo- and active-controlled trials, as well as open-label extension studies that followed them, a total of 1,988 patients treated with Repatha® had at least one LDL-C value <25 mg/dL. Changes to background lipid-altering therapy were not made in response to low LDL-C values, and Repatha® dosing was not modified or interrupted on this basis. Although adverse consequences of very low LDL-C were not identified in these trials, the long-term effects of very low levels of LDL-C induced by Repatha® are unknown.
Musculoskeletal adverse reactions were reported in 14.3% of Repatha® -treated patients and 12.8% of placebo-treated patients. The most common adverse reactions that occurred at a rate greater than placebo were back pain (3.2% versus 2.9% for Repatha® and placebo, respectively), arthralgia (2.3% versus 2.2%), and myalgia (2.0% versus 1.8%).
Homozygous Familial Hypercholesterolemia (HoFH): In 49 patients with homozygous familial hypercholesterolemia studied in a 12-week, double-blind, randomized, placebo-controlled trial, 33 patients received 420 mg of Repatha® subcutaneously once monthly. The adverse reactions that occurred in at least 2 (6.1%) Repatha®-treated patients and more frequently than in placebo-treated patients, included upper respiratory tract infection (9.1% versus 6.3%), influenza (9.1% versus 0%), gastroenteritis (6.1% versus 0%), and nasopharyngitis (6.1% versus 0%).
Immunogenicity: Repatha® is a human monoclonal antibody. As with all therapeutic proteins, there is a potential for immunogenicity with Repatha®.
