DUBLIN, Ireland and BRIDGEWATER, N.J., April 01, 2022 (GLOBE NEWSWIRE) -- Amarin Corporation plc (NASDAQ: AMRN) today announced in vitro research results suggesting that Eicosapentaenoic Acid (EPA), in combination with widely prescribed statins (often referred to under brand names LIPITOR® and CRESTOR®), contributed to a reduction in lipid oxidation in membranes in a manner that may be enhanced with the use of these statins.

Amarin’s VASCEPA®/VAZKEPA® (icosapent ethyl) is the highly purified, prescription form of the ethyl ester of EPA. The research results will be presented on behalf of all authors by Preston Mason, Ph.D., of Brigham & Women’s Hospital and Elucida Research, LLC, during a poster session at the American College of Cardiology’s 71st Annual Scientific Session in Washington, DC, on Saturday, April 2nd. The experiment was conducted with financial support from Amarin and Elucida Research.

The oxidation of lipids in vascular cell membranes can be an important factor in heart disease and risk of an adverse cardiovascular event, as it contributes to inflammation, endothelial dysfunction, and cholesterol domain and foam cell formation during atherogenesis,1-3 as well as to circulating levels of oxidized LDL, which correlate with acute coronary syndromes and increased risk for ischemic events (such as a heart attack or stroke) and metabolic disease.4-7

In this experiment, the dose-dependent effects of EPA at concentrations of 5 and 10 micromolar (µM) on rates of lipid oxidation were measured by iodometric approaches with fixed concentrations of ATM and rosuva (1.0 µM) under conditions of autoxidation for 96 hr. After 96 h, control (untreated) membranes underwent significant oxidation with lipid peroxide (LOOH) levels reaching 2049 ± 286 µM.

EPA was found to have significantly reduced lipid oxidation in a dose-dependent fashion in the absence and presence of either ATM or rosuva. The combination of EPA/ATM and EPA/rosuva reduced lipid oxidation by 86 and 75%, respectively (ppp

These results are in line with prior experiments which suggested that treatment with EPA inhibited endothelial dysfunction following challenge with oxidized LDL and high glucose levels in a manner that may be enhanced with a high-intensity statin.8 The authors posit that this may be due to increased antioxidant activity achieved via the combination of EPA with statins due to complementary physico-chemical properties.

“The message that emerged for us from these in vitro study results was that, while statins and EPA can work independently to reduce lipid oxidation which can contribute to cardiovascular risk, they might work even better together,” said Dr. Mason. “This is an important finding with potential implications in particular for those facing persistent, elevated cardiovascular risk or who have had a prior event, as they may need more potent solutions than the standard of care can provide.”

“These findings are another compelling piece of evidence in line with our beliefs regarding the potential for increased benefit to appropriate high-risk patients from VASCEPA/VAZKEPA in combination with statins, consistent with the results from the REDUCE-IT® trial, and supports Amarin’s decision to focus on research and development efforts toward the possible development of a combination product,” said Karim Mikhail, Amarin’s president and chief executive officer.

About Amarin
Amarin is an innovative pharmaceutical company leading a new paradigm in cardiovascular disease management. From our foundation in scientific research to our focus on clinical trials, and now our commercial expansion, we are evolving and growing rapidly. 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. We are committed to increasing the scientific understanding of the cardiovascular risk that persists beyond traditional therapies and advancing the treatment of that risk.

About VASCEPA® (icosapent ethyl) Capsules
VASCEPA (icosapent ethyl) capsules are the first-and-only 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 and only drug approved by the U.S. FDA for treatment of the studied high-risk patients with persistent cardiovascular risk after 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 over ten million times. VASCEPA is covered by most major medical insurance plans. In addition to the United States, VASCEPA is approved and sold in Canada, 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.

Indications and Limitation of Use (in the United States)

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.
