THOUSAND OAKS, Calif., Jan. 24, 2019 /PRNewswire/ -- Amgen (NASDAQ:AMGN) today announced that the National Medical Products Administration (NMPA) has approved a new indication for Repatha^® (evolocumab) as the first PCSK9 inhibitor in China for adults with established atherosclerotic cardiovascular disease (ASCVD) to reduce the risk of myocardial infarction, stroke and coronary revascularization.

Low-density lipoprotein cholesterol (LDL-C) is one of the key modifiable risk factors for the development of cardiovascular disease.^1,2 Decades of studies have demonstrated that reductions in cardiovascular risk are proportional to absolute reductions in LDL-C levels, making LDL-C the primary treatment target for the reduction of cardiovascular events.^3,4 Yet, even among patients with cardiovascular disease currently taking a lipid-lowering therapy, many still do not meet recommended LDL-C goals and remain at risk for cardiovascular events.⁵

Repatha is an innovative biologic medicine proven to effectively lower LDL-C. It inhibits circulating proprotein convertase subtilisin/kexin type 9 (PCSK9) from binding to LDL receptors (LDLR). By inhibiting the binding of PCSK9 to LDLR, Repatha increases the number of LDLRs available to clear LDL from the blood, thereby significantly lowering LDL-C levels, and further preventing the risk of myocardial infarction and stroke.⁶

"The new expanded label in China is an important milestone providing high-risk patients, who are unable to control their LDL-C with statin therapy alone, with a new treatment option to help prevent life-changing heart attacks and strokes," said Murdo Gordon, executive vice president of Global Commercial Operations at Amgen. "This is also an important step for Amgen as we continue to bring innovative medicines to China and build our presence."

The approval of the extended label recognizes the positive findings from the 27,564-patient Repatha cardiovascular outcomes study (FOURIER). Compared to placebo plus statin therapy, patients on Repatha in combination with statin therapy, experienced a reduction in the risk of heart attack by 27 percent, the risk of stroke by 21 percent and the risk of coronary revascularization by 22 percent, accruing through the median 26 months of the study.⁷ Moreover, the results from a FOURIER subanalysis demonstrated consistent efficacy and safety in the reduction of cardiovascular events using Repatha in Asian populations versus those from non-Asian backgrounds.⁸

"Cardiovascular disease has become one of the greatest health challenges facing Chinese citizens today," said Professor Changsheng Ma, Beijing Anzhen Hospital, Capital Medical University. "High levels of LDL-C have been proven to increase the risk of developing ASCVD. If such levels of LDL-C fail to be managed, patients will become increasingly susceptible to strokes and heart attacks. However, existing therapies have limitations and many patients fail to effectively control their LDL-C levels to prevent recurrent cardiovascular events. The approval of this new indication offers hope for patients who continue to struggle with achieving lower LDL-C levels, providing another treatment against cardiovascular events."

On July 31, 2018, Repatha was approved by the NMPA as the first PCSK9 inhibitor in China for the treatment of adults and adolescents over 12 years old with homozygous familial hypercholesterolemia (HoFH).

About Repatha^® (evolocumab)
Repatha 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.⁶

Repatha is approved in more than 60 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.

Repatha Cardiovascular Outcomes (FOURIER) Study Design
FOURIER (Further Cardiovascular OUtcomes Research with PCSK9 Inhibition in subjects with Elevated Risk), a multinational Phase 3 randomized, double-blind, placebo-controlled trial, is designed to evaluate whether treatment with Repatha in combination with high- or moderate-intensity statin therapy compared to placebo plus statin therapy reduces cardiovascular events. The hard MACE composite endpoint is the time to cardiovascular death, myocardial infarction or stroke (key secondary endpoint). The extended MACE composite endpoint is the time to cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina or coronary revascularization (primary endpoint).

Eligible patients with high cholesterol (LDL-C ≥70 mg/dL or non-high-density lipoprotein cholesterol [non-HDL-C] ≥100 mg/dL) and established cardiovascular disease at more than 1,300 study locations around the world were randomized to receive Repatha subcutaneous 140 mg every two weeks or 420 mg monthly plus high- or moderate-intensity effective statin dose; or placebo subcutaneous every two weeks or monthly plus high- to moderate-intensity statin dose. Statin therapy was defined in the protocol as at least atorvastatin 20 mg or equivalent daily with a recommendation for at least atorvastatin 40 mg or equivalent daily where approved. The study was event driven and continued until at least 1,630 patients experienced a key secondary endpoint.

Important China Product Information

Repatha is indicated in adults with established atherosclerotic cardiovascular disease to reduce the risk of myocardial infarction, stroke, and coronary revascularization:

in combination with the maximum tolerated dose of a statin with or without other lipid-lowering therapies or,
alone or in combination with other lipid-lowering therapies in patients who are statin-intolerant, or for whom a statin is contraindicated.

Repatha is indicated in adults and adolescents aged 12 years over with homozygous familial hypercholesterolemia as an adjunct to diet and other low-density lipoprotein cholesterol (LDL-C) lowering therapies (e.g., statins, ezetimibe, LDL apheresis) for the treatment of patients with homozygous familial hypercholesterolemia (HoFH) who require additional lowering of LDL-C.

Important China Safety Information

Contraindication: Repatha is contraindicated in patients with a history of a serious hypersensitivity reaction to Repatha.

Allergic reactions: Hypersensitivity reactions (e.g. angioedema, 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.

This news release contains forward-looking statements that are based on the current expectations and beliefs of Amgen. All statements, other than statements of historical fact, are statements that could be deemed forward-looking statements, including estimates of revenues, operating margins, capital expenditures, cash, other financial metrics, expected legal, arbitration, political, regulatory or clinical results or practices, customer and prescriber patterns or practices, reimbursement activities and outcomes and other such estimates and results. Forward-looking statements involve significant risks and uncertainties, including those discussed below and more fully described in the Securities and Exchange Commission reports filed by Amgen, including our most recent annual report on Form 10-K and any subsequent periodic reports on Form 10-Q and current reports on Form 8-K. Unless otherwise noted, Amgen is providing this information as of the date of this news release and does not undertake any obligation to update any forward-looking statements contained in this document as a result of new information, future events or otherwise.

No forward-looking statement can be guaranteed and actual results may differ materially from those we project. Discovery or identification of new product candidates or development of new indications for existing products cannot be guaranteed and movement from concept to product is uncertain; consequently, there can be no guarantee that any particular product candidate or development of a new indication for an existing product will be successful and become a commercial product. Further, preclinical results do not guarantee safe and effective performance of product candidates in humans. The complexity of the human body cannot be perfectly, or sometimes, even adequately modeled by computer or cell culture systems or animal models. The length of time that it takes for us to complete clinical trials and obtain regulatory approval for product marketing has in the past varied and we expect similar variability in the future. Even when clinical trials are successful, regulatory authorities may question the sufficiency for approval of the trial endpoints we have selected. We develop product candidates internally and through licensing collaborations, partnerships and joint ventures. Product candidates that are derived from relationships may be subject to disputes between the parties or may prove to be not as effective or as safe as we may have believed at the time of entering into such relationship. Also, we or others could identify safety, side effects or manufacturing problems with our products, including our devices, after they are on the market.

Our results may be affected by our ability to successfully market both new and existing products domestically and internationally, clinical and regulatory developments involving current and future products, sales growth of recently launched products, competition from other products including biosimilars, difficulties or delays in manufacturing our products and global economic conditions. In addition, sales of our products are affected by pricing pressure, political and public scrutiny and reimbursement policies imposed by third-party payers, including governments, private insurance plans and managed care providers and may be affected by regulatory, clinical and guideline developments and domestic and international trends toward managed care and healthcare cost containment. Furthermore, our research, testing, pricing, marketing and other operations are subject to extensive regulation by domestic and foreign government regulatory authorities. Our business may be impacted by government investigations, litigation and product liability claims. In addition, our business may be impacted by the adoption of new tax legislation or exposure to additional tax liabilities. While we routinely obtain patents for our products and technology, the protection offered by our patents and patent applications may be challenged, invalidated or circumvented by our competitors, or we may fail to prevail in present and future intellectual property litigation. We perform a substantial amount of our commercial manufacturing activities at a few key facilities, including in Puerto Rico, and also depend on third parties for a portion of our manufacturing activities, and limits on supply may constrain sales of certain of our current products and product candidate development. In addition, we compete with other companies with respect to many of our marketed products as well as for the discovery and development of new products. Further, some raw materials, medical devices and component parts for our products are supplied by sole third-party suppliers. Certain of our distributors, customers and payers have substantial purchasing leverage in their dealings with us. The discovery of significant problems with a product similar to one of our products that implicate an entire class of products could have a material adverse effect on sales of the affected products and on our business and results of operations. Our efforts to acquire other companies or products and to integrate the operations of companies we have acquired may not be successful. A breakdown, cyberattack or information security breach could compromise the confidentiality, integrity and availability of our systems and our data. Our stock price is volatile and may be affected by a number of events. Our business performance could affect or limit the ability of our Board of Directors to declare a dividend or our ability to pay a dividend or repurchase our common stock. We may not be able to access the capital and credit markets on terms that are favorable to us, or at all.
