Investigators to Present New REDUCE-IT Subanalysis of VASCEPA®/VAZKEPA® (icosapent ethyl) in Patients With and Without Coronary Artery Disease History and Mechanistic Data on Eicosapentaenoic Acid (EPA) at the American Heart Association’s (AHA) Annual

Amarin Corporation plc (NASDAQ:AMRN) today announced that investigators will present an additional subgroup analysis from the landmark REDUCE-IT outcomes trial in patients with and without coronary artery disease (CAD) history and mechanistic data on eicosapentaenoic acid (EPA) at the American Heart Association’s Scientific Sessions, November 16-18, 2024 in Chicago, IL.

"The data to be presented at the AHA Scientific Sessions continues to affirm the clinical utility and value of VASCEPA®/VAZKEPA® (icosapent ethyl), not only in the overall REDUCE-IT trial population, but also across various subgroups analyzed to date," said Steve Ketchum, PhD, Chief Scientific Officer at Amarin. "Data presented at AHA will showcase new evidence from the REDUCE-IT CAD subanalysis, highlighting the benefits of VASCEPA/VAZKEPA in secondary prevention patients, with and without CAD history."

Dr. Ketchum further added, "Additional data to be featured at the AHA Scientific Sessions include research highlighting the mechanistic effects of EPA, particularly its antioxidant effects in endothelial cells and the ability of EPA to impact the oxidation of Lp(a) particles. High Lp(a) concentrations are associated with increased CV event risk, and people with high levels face a 2-4 times greater risk of having an early event. With about 20% of the global population affected, research is crucial for understanding and addressing elevated Lp(a)."

"This latest research reinforces Amarin’s commitment to advancing cardiovascular care and enhancing the medical community’s understanding of the value, mechanism of action, and global potential of VASCEPA/VAZKEPA in reducing cardiovascular events in high-risk patients," concluded Dr. Ketchum.

About Amarin Amarin is an innovative pharmaceutical company leading a new paradigm in cardiovascular disease management. We are committed to increasing the scientific understanding of the cardiovascular risk that persists beyond traditional therapies and advancing the treatment of that risk for patients worldwide. Amarin has offices in Bridgewater, New Jersey in the United States, Dublin in Ireland, Zug in Switzerland, and other countries in Europe as well as commercial partners and suppliers around the world.  

About Cardiovascular RiskCardiovascular disease is the number one cause of death in the world. In the United States alone, cardiovascular disease results in 859,000 deaths per year.1  And the number of deaths in the United States attributed to cardiovascular disease continues to rise. In addition, in the United States there are 605,000 new and 200,000 recurrent heart attacks per year (approximately 1 every 40 seconds). Stroke rates are 795,000 per year (approximately 1 every 40 seconds), accounting for 1 of every 19 U.S. deaths. In aggregate, in the United States alone, there are more than 2.4 million major adverse cardiovascular events per year from cardiovascular disease or, on average, 1 every 13 seconds.

Controlling bad cholesterol, also known as LDL-C, is one way to reduce a patient’s risk for cardiovascular events, such as heart attack, stroke or death. However, even with the achievement of target LDL-C levels, millions of patients still have significant and persistent risk of cardiovascular events, especially those patients with elevated triglycerides. Statin therapy has been shown to control LDL-C, thereby reducing the risk of cardiovascular events by 25-35%.2 Significant cardiovascular risk remains after statin therapy. People with elevated triglycerides have 35% more cardiovascular events compared to people with normal (in range) triglycerides taking statins.3,4

About VASCEPA®/VAZKEPA® (icosapent ethyl) Capsules  VASCEPA (icosapent ethyl) capsules are the first prescription treatment approved by the U.S. Food and Drug Administration (FDA) comprised solely of the active ingredient, icosapent ethyl (IPE), a unique form of eicosapentaenoic acid. VASCEPA was launched in the United States in January 2020 as the first drug approved by the U.S. FDA for treatment of the studied high-risk patients with persistent cardiovascular risk despite being on statin therapy. VASCEPA was initially launched in the United States in 2013 based on the drug’s initial FDA approved indication for use as an adjunct therapy to diet to reduce triglyceride levels in adult patients with severe (≥500 mg/dL) hypertriglyceridemia. Since launch, VASCEPA has been prescribed more than twenty million times. VASCEPA is covered by most major medical insurance plans. In addition to the United States, VASCEPA is approved and sold in Canada, China, Lebanon and the United Arab Emirates. In Europe, in March 2021 marketing authorization was granted to icosapent ethyl in the European Union for the reduction of risk of cardiovascular events in patients at high cardiovascular risk, under the brand name VAZKEPA. In April 2021 marketing authorization for VAZKEPA (icosapent ethyl) was granted in Great Britain (applying to England, Scotland and Wales). VAZKEPA (icosapent ethyl) is currently approved and sold in Europe in Sweden, Denmark, Finland, Austria, the UK, Spain and the Netherlands.   United States  Indications and Limitation of Use  VASCEPA is indicated:    

• As an adjunct to maximally tolerated statin therapy to reduce the risk of myocardial infarction, stroke, coronary revascularization and unstable angina requiring hospitalization in adult patients with elevated triglyceride (TG) levels (≥ 150 mg/dL) and  
  • established cardiovascular disease or  
  • diabetes mellitus and two or more additional risk factors for cardiovascular disease.  
• As an adjunct to diet to reduce TG levels in adult patients with severe (≥ 500 mg/dL) hypertriglyceridemia.  

The effect of VASCEPA on the risk for pancreatitis in patients with severe hypertriglyceridemia has not been determined.  

Important Safety Information  

• VASCEPA is contraindicated in patients with known hypersensitivity (e.g., anaphylactic reaction) to VASCEPA or any of its components.  
• VASCEPA was associated with an increased risk (3% vs 2%) of atrial fibrillation or atrial flutter requiring hospitalization in a double-blind, placebo-controlled trial. The incidence of atrial fibrillation was greater in patients with a previous history of atrial fibrillation or atrial flutter.  
• It is not known whether patients with allergies to fish and/or shellfish are at an increased risk of an allergic reaction to VASCEPA. Patients with such allergies should discontinue VASCEPA if any reactions occur.  
• VASCEPA was associated with an increased risk (12% vs 10%) of bleeding in a double-blind, placebo-controlled trial. The incidence of bleeding was greater in patients receiving concomitant antithrombotic medications, such as aspirin, clopidogrel or warfarin.  
• Common adverse reactions in the cardiovascular outcomes trial (incidence ≥3% and ≥1% more frequent than placebo): musculoskeletal pain (4% vs 3%), peripheral edema (7% vs 5%), constipation (5% vs 4%), gout (4% vs 3%), and atrial fibrillation (5% vs 4%).  
• Common adverse reactions in the hypertriglyceridemia trials (incidence >1% more frequent than placebo): arthralgia (2% vs 1%) and oropharyngeal pain (1% vs 0.3%).  
• Adverse events may be reported by calling 1-855-VASCEPA or the FDA at 1-800-FDA-1088.  
• Patients receiving VASCEPA and concomitant anticoagulants and/or anti-platelet agents should be monitored for bleeding.
