New Analyses from REDUCE-IT® and EPA Mechanistic Data to be Presented at the European Society of Cardiology (ESC) Congress 2025

DUBLIN and BRIDGEWATER, N.J., Aug. 25, 2025 (GLOBE NEWSWIRE) -- Amarin Corporation plc (NASDAQ:AMRN) today announced upcoming presentations at the European Society of Cardiology (ESC) Congress 2025, August 29 ^th -September 1 ^st , in Madrid, Spain, where new data will further illuminate the multifaceted cardioprotective effects of icosapent ethyl (IPE).

Data to be featured at ESC 2025 will provide deeper insight into the potential role of IPE in reducing cardiovascular (CV) risk through multiple mechanisms, including effects on inflammation, lipoprotein oxidation, CV risk associated with CV-kidney-metabolic (CKM) syndrome, and risk and duration of hospitalizations. Highlights include new analyses from the REDUCE-IT trial evaluating the clinical benefit of IPE, alongside mechanistic studies investigating the impact of eicosapentaenoic acid (EPA) on inflammasome activation, lipoprotein(a) [Lp(a)] oxidation, and pro-inflammatory protein expression in endothelial cells under conditions of oxidative stress.

“The data being featured at ESC continue to reinforce the clinical value of IPE in reducing cardiovascular risk across specific patient subtypes. These new REDUCE-IT post hoc analyses not only support the primary outcomes data but also provide important, hypothesis-generating insights into the impact of IPE on the risk and duration of hospitalizations, CV risk associated with CKM syndrome, and major adverse CV event (MACE) endpoint stratified by apolipoproteinB (ApoB) and triglyceride-rich lipoprotein-cholesterol (TRL-C) levels,” said Steven Ketchum, Ph.D., EVP, President of R&D, and Chief Scientific Officer at Amarin. “Additionally, the mechanistic findings—including the effects of EPA on Lp(a) oxidation, pro-inflammatory protein expression in endothelial cells, and on modulating the activation of the NLRP3 inflammasome—advance our understanding of the underlying science of this molecule. Together, these results deepen the medical community’s understanding of the role of IPE in cardiovascular care and its potential mechanisms of action.”

Amarin’s presentations will include both oral presentations and moderated poster presentations, reinforcing the company’s commitment to advancing the science of cardiovascular care and addressing residual risk in patients worldwide. Amarin will also be supporting educational programing addressing residual cardiovascular risk by medical and scientific leaders in Europe.

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-five 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, Australia, Lebanon, the United Arab Emirates, Saudi Arabia, Qatar, Bahrain, and Kuwait. 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, Finland, England/Wales, Spain, Netherlands, Scotland, Greece, Portugal, Italy, Denmark and Austria.

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.
