• Subgroup Analyses from REDUCE-IT® and Mechanistic Data on Icosapent Ethyl(IPE)/Eicosapentaenoic Acid (EPA) Featured at the Meeting  

DUBLIN, Ireland and BRIDGEWATER, N.J., March 25, 2024 (GLOBE NEWSWIRE) -- Amarin Corporation plc (NASDAQ:AMRN) today announced that additional patient subgroup analyses from the landmark REDUCE-IT outcomes trial and mechanistic data on icosapent ethyl (IPE)/eicosapentaenoic acid (EPA) will be presented at the American College of Cardiology’s Annual Scientific Session & Expo, April 6 – 8, 2024 in Atlanta, GA.

"The data being featured at ACC.24 continues to support and explain the clinical utility and value of VASCEPA®/VAZKEPA® (icosapent ethyl), not only in the overall REDUCE IT patient population, but in the different sub-populations analyzed so far,” said Nabil Abadir, MB. CH.B., SVP, Chief Medical Officer, and Head of Global Medical Affairs at Amarin "The data highlight VASCEPA/VAZKEPA’s effect on reducing MACE in patients with different baseline levels of Lipoprotein(a) [Lp(a)] including among those with clinically relevant Lp(a) elevation as well as among patients with high and low LDL-C baseline levels. These data demonstrate the molecule’s impact in reducing patients’ residual cardiovascular event risk across these patient sub-groups regardless of their baseline Lp(a) or LDL-C levels. Additionally, the meeting provides an opportunity to highlight further evidence regarding the potential mechanistic activity of EPA in reducing cardiovascular events in at-risk patients."

“This latest research reaffirms Amarin's commitment to advancing cardiovascular care and should help further advance the medical community’s understanding of the role, the value and the potential mechanism of action of VASCEPA/VAZKEPA to reduce cardiovascular events in at-risk patients globally,” concluded Abadir.

About Cardiovascular Risk

Cardiovascular 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.

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.
