Peer-reviewed paper indicates icosapent ethyl (IPE) was associated with fewer total hospitalizations and fewer days lost due to hospitalization and death, providing additional insights on the effects of IPE on patient-centered measures of total disease burden

DUBLIN and BRIDGEWATER, N.J., March 02, 2026 (GLOBE NEWSWIRE) -- Amarin Corporation plc (NASDAQ:AMRN), a company committed to advancing the science of cardiovascular disease (CVD) worldwide, today highlighted recently published data in the European Journal of Preventive Cardiology showing in a post hoc analysis of the landmark REDUCE-IT study that, among statin-treated participants with elevated triglycerides and known CVD or with diabetes and other risk factors, patients treated with VASCEPA^®/VAZKEPA^® (icosapent ethyl) (IPE) experienced fewer total hospitalizations and fewer days lost due to hospitalization and death, providing additional insights on the effects of IPE on patient-centered measures of total disease burden.ⁱ

The analysis evaluated 8,179 participants randomized to receive either IPE 2 g twice daily or placebo and followed for a median of five years and determined if treatment with IPE would decrease the frequency and duration of hospitalizations.

Commenting on the published findings, Deepak L. Bhatt, MD, MPH, MBA, Director of the Mount Sinai Fuster Heart Hospital at the Icahn School of Medicine at Mount Sinai in New York, said, "What stands out most in this analysis is the real-world relevance for patients and their families. Fewer hospitalizations can make a meaningful difference in daily life - allowing people to maintain independence and spend more time at home. These findings extend the benefits of treatment with IPE beyond cardiovascular prevention to potentially reduce the burden of hospitalizations and increase the chances of an individual living without hospitalization."

Lead author Michael Szarek, PhD, Mount Sinai Fuster Heart Hospital at the Icahn School of Medicine at Mount Sinai in New York and University of Colorado Anschutz Medical Campus, Aurora, CO, added: "For patients already managing heart disease or diabetes, every day outside the hospital matters. In this high-risk population, we saw reductions not only in how often individuals were hospitalized, but also in how much time they lost to being in the hospital or from premature death. These patient focused outcomes reinforce that IPE may help people spend more time living their lives and less time receiving acute medical care - a result with great significance for patients, their families, and the healthcare system at large."

Data from REDUCE-IT have consistently shown robust relative and absolute risk reductions in the primary analyses and several sub-group analyses, which led to incorporation of IPE in multiple guidelines and consensus statements globally.ⁱⁱ

About the Analysis

In this post hoc analysis of REDUCE-IT, investigators quantified the effects of IPE on total hospitalizations and days lost to hospitalization and death.

Among 8,179 statin-treated REDUCE-IT patients with established cardiovascular disease or age ≥50 years with diabetes and ≥1 additional risk factor, fasting triglyceride 1.69-5.63 mmol/L (135-499 mg/dL), and low-density lipoprotein cholesterol 1.06-2.59 mmol/L (41-100 mg/dL), total hospitalizations were analyzed with a competing risks marginal model for total events. The likelihood of no days lost to hospitalization and death and the rate of days lost among those who were hospitalized or died during the study were analyzed with a zero-inflated Poisson regression model. During a median 5.0 years of follow-up, IPE treatment was associated with fewer total hospitalizations (HR (95% CI) = 0.91 (0.84, 0.98), P = 0.017). Participants randomized to IPE were more likely to survive until the end of the study without hospitalization (OR (95% CI) = 1.12 (1.02, 1.22), P = 0.016) and had fewer days lost among those who were hospitalized or died (RR (95% CI) = 0.93 (0.93, 0.94), P < 0.001).

In conclusion, IPE was associated with fewer total hospitalizations and fewer days lost due to hospitalization and death, providing additional insights on the effects of IPE on patient-centered measures of total disease burden.

The analysis highlighted above was funded by Amarin. Dr. Deepak L. Bhatt served as the principal investigator for REDUCE-IT and his institution received research funding from Amarin.

About REDUCE-IT^®

REDUCE-IT was a global cardiovascular outcomes study designed to evaluate the effect of VASCEPA in adult patients with LDL-C controlled to between 41-100 mg/dL (median baseline 75 mg/dL) by statin therapy and various cardiovascular risk factors including persistent elevated triglycerides between 135-499 mg/dL (median baseline 216 mg/dL) and either established cardiovascular disease (secondary prevention cohort) or diabetes mellitus and at least one other cardiovascular risk factor (primary prevention cohort).

REDUCE-IT, conducted over seven years and completed in 2018, followed 8,179 patients at over 400 clinical sites in 11 countries with the largest number of sites located within the United States. REDUCE-IT was conducted based on a special protocol assessment agreement with FDA. The design of the REDUCE-IT study was published in March 2017 in Clinical Cardiology.ⁱⁱⁱ The primary results of REDUCE-IT were published in The New England Journal of Medicine in November 2018.^iv The total events results of REDUCE-IT were published in the Journal of the American College of Cardiology in March 2019.^v These and other publications can be found in the R&D section on the company's website at www.amarincorp.com.

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.^vi 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%.^vii 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.^viii^,^ix^,^x

About VASCEPA^®/VAZKEPA^® (icosapent ethyl) Capsules

VASCEPA 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 was granted in Great Britain (applying to England, Scotland and Wales). VAZKEPA 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.
