AMGEN'S REPATHA® CUTS RISK OF FIRST MAJOR ADVERSE CARDIOVASCULAR EVENTS BY 25% IN LANDMARK PHASE 3 VESALIUS-CV TRIAL

Study Also Shows 36% Reduction in Risk of Heart Attack 

Repatha is the First and Only PCSK9 Inhibitor to Significantly Reduce the Risk of First Heart Attack and Stroke

THOUSAND OAKS, Calif., Nov. 8, 2025 /PRNewswire/ -- Amgen (NASDAQ:AMGN) today announced detailed results from the Phase 3 VESALIUS-CV clinical trial, which showed that Repatha® (evolocumab) achieved statistically significant and clinically meaningful reductions in major adverse cardiovascular events (MACE) in high-risk adults without a prior heart attack or stroke, when added to statins or other low-density lipoprotein cholesterol (LDL-C)–lowering treatments. Repatha is the first and only PCSK9 inhibitor to demonstrate a significant reduction of cardiovascular events as both high-risk primary and secondary prevention. The results were presented in a late-breaking session at the 2025 American Heart Association Scientific Sessions and simultaneously published in the New England Journal of Medicine

In this landmark study of more than 12,000 patients with atherosclerosis or diabetes who had no prior heart attack or stroke, Repatha demonstrated a 25% relative reduction in the risk of a composite of coronary heart disease (CHD) death, heart attack or ischemic stroke (3-P MACE), and 19% reduction in a broader composite that also included any ischemia-driven arterial revascularization (4-P MACE). Repatha also reduced the risk of heart attack by 36%. In a cohort of patients included in a lipid sub-study, the median achieved LDL-C was 45 mg/dL compared to 109 mg/dL in the placebo arm. 

"The VESALIUS-CV results deliver clear and compelling evidence that intensive LDL-C lowering is critical to reducing cardiovascular risk," said Jay Bradner, M.D., executive vice president of Research and Development at Amgen. "Repatha has once again demonstrated its ability to protect patients from the cardiovascular events they fear most, like heart attack or stroke, even before one occurs. These findings reinforce the urgent need to translate today's evidence into tomorrow's clinical practice. With a decade of real-world experience and proven benefit across the continuum of cardiovascular disease, every patient facing elevated risk due to uncontrolled LDL-C should be considered for Repatha."

Repatha significantly reduced the risk of most secondary endpoints, including the following composites: heart attack, ischemic stroke or any ischemia-driven revascularization; CHD death, heart attack or revascularization; cardiovascular death, heart attack or ischemic stroke; and CHD death or heart attack. In addition, there were numerical trends for reduced mortality rates in the Repatha arm, including cardiovascular death (21% relative risk reduction), CHD death (11% relative risk reduction) and all-cause death (20% relative risk reduction), as well as a trend toward lower ischemic stroke (21% relative risk reduction).

"Building on the success of FOURIER, in which we showed that adding evolocumab to statin therapy in patients with a prior heart attack or stroke reduced the risk of subsequent major adverse cardiovascular events, we now show that in the much larger population of patients with atherosclerosis or diabetes, but without a prior heart attack or stroke, that adding evolocumab to their lipid regimen substantially reduces their risk of MACE," said Marc S. Sabatine, M.D., M.P.H., Chair of the TIMI Study Group and the Lewis Dexter, MD, Endowed Chair in Cardiovascular Medicine at Brigham and Women's Hospital. "In both FOURIER and VESALIUS-CV, patients in the evolocumab arm achieved median LDL-C levels in the range of approximately 30 to 45 mg/dL, supporting such a target across a broad range of patients." 

Results also showed reduction in risk of cardiovascular events in the nearly 60% of trial participants who had diabetes, reinforcing the urgent need to manage LDL-C in these patients who remain largely undertreated.

"Cardiovascular disease remains the leading cause of mortality and morbidity for people living with diabetes, driven by risk factors including high LDL-C. Reducing this risk needs to be prioritized in primary care settings where the majority of people living with diabetes receive care," said Osagie Ebekozien M.D., M.P.H., CPHQ, Chief Quality Officer, American Diabetes Association. "The American Diabetes Association is committed to transforming diabetes care through the implementation of evidence-based guidelines for managing hyperlipidemia and reducing cardiovascular risk."

No new safety signals were identified, and tolerability was consistent with the current prescribing information in the U.S. Only treatment-emergent adverse events that were serious or led to discontinuation were captured. 

Cardiovascular disease is the leading cause of death worldwide.1 Every 40 seconds, a heart attack or stroke occurs in the U.S., and 75% of those are first-time events.1 Recent research shows that more than 99% of people who experience a first-time cardiovascular event have at least one traditional risk factor, including high LDL-C which is one of the most modifiable risk factors for heart attack or stroke.2

Repatha was first approved in 2015 and has since been used by more than 6.7 million patients globally.3,4 Earlier this year, the U.S. Food and Drug Administration broadened the approved use of Repatha to include adults at increased risk for major adverse CV events due to uncontrolled LDL-C. All U.S. patients can now access Repatha through AmgenNow, the company's direct-to-patient program, at a monthly price of $239, nearly 60% lower than the current U.S. list price.

About the VESALIUS-CV Trial
VESALIUS-CV is a Phase 3, double-blind, randomized, placebo-controlled global clinical trial designed to evaluate the impact of LDL-C lowering with evolocumab on MACE in adults at high CV risk without prior heart attack or stroke. 

VESALIUS-CV enrolled more than 12,000 patients with known atherosclerotic cardiovascular disease (ASCVD) or high-risk diabetes, who had no history of heart attack or stroke, an LDL-C ≥ 90 mg/dL, or non-high-density lipoprotein cholesterol (non-HDL-C) ≥ 120 mg/dL, or apolipoprotein B ≥ 80 mg/dL; and treated with highest tolerated dose of statin and/or ezetimibe. The median baseline LDL-C was 122 mg/dL (IQR, 104-149 mg/dL) on local lab testing. Participants were randomized to receive Repatha or placebo in addition to optimized lipid-lowering therapy and were followed for a median of approximately 4.6 years. 

Amgen's Commitment to Cardiovascular Innovation
Cardiovascular disease (CVD) remains a major global health threat, linked to multiple interrelated risk factors like high LDL-C, Lp(a), obesity, diabetes and hypertension.5,6 These risks often coexist and require a comprehensive approach to prevention and care. Amgen is taking bold action, building on decades of leadership in CVD through LDL-C management to advance additional innovative, investigational treatments in the pipeline targeting common drivers of CVD. By combining scientific innovation with strategic partnerships to drive earlier testing, better care and broader access, Amgen's efforts reflect a sustained commitment to advancing both the science and the system of CV care.

About Repatha
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. 

Repatha is the most extensively studied PCSK9 inhibitor, with clinical and real-world evidence across diverse populations and CV risk profiles.7 The clinical benefits and safety of Repatha have been studied for 15 years in 51 clinical trials with over 57,000 patients.8 Repatha is approved in 74 countries, including the U.S., Japan, Canada and in all 28 countries that are members of the European Union.9 Applications in other countries are pending.

All statements, other than statements of historical fact, are statements that could be deemed forward-looking statements, including any statements on the outcome, benefits and synergies of collaborations, or potential collaborations, with any other company (including BeOne Medicines Ltd. or Kyowa Kirin Co., Ltd.), the performance of Otezla® (apremilast), our acquisitions of ChemoCentryx, Inc. or Horizon Therapeutics plc (including the prospective performance and outlook of Horizon's business, performance and opportunities, and any potential strategic benefits, synergies or opportunities expected as a result of such acquisition), as well as 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, effects of pandemics or other widespread health problems on our business, outcomes, progress, 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, including those resulting from geopolitical relations and government actions. 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. Further, 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. An outbreak of disease or similar public health threat, and the public and governmental effort to mitigate against the spread of such disease, could have a significant adverse effect on the supply of materials for our manufacturing activities, the distribution of our products, the commercialization of our product candidates, and our clinical trial operations, and any such events may have a material adverse effect on our product development, product sales, business and results of operations. We rely on collaborations with third parties for the development of some of our product candidates and for the commercialization and sales of some of our commercial products. 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 collaborate with or acquire other companies, products or technology, and to integrate the operations of companies or to support the products or technology we have acquired, may not be successful. There can be no guarantee that we will be able to realize any of the strategic benefits, synergies or opportunities arising from the Horizon acquisition, and such benefits, synergies or opportunities may take longer to realize than expected. We may not be able to successfully integrate Horizon, and such integration may take longer, be more difficult or cost more than expected. A breakdown, cyberattack or information security breach of our information technology systems 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 and operations may be negatively affected by the failure, or perceived failure, of achieving our sustainability objectives. The effects of global climate change and related natural disasters could negatively affect our business and operations. Global economic conditions may magnify certain risks that affect our business. 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.

Any scientific information discussed in this news release relating to new indications for our products is preliminary and investigative and is not part of the labeling approved by the U.S. Food and Drug Administration for the products.
