DUBLIN, Ireland and BRIDGEWATER, N.J. - Amarin Corporation plc (NASDAQ:AMRN) announced new supported and/or funded research on the effects of VASCEPA/VAZKEPA (icosapent ethyl) in specific patient subgroups at increased risk of a cardiovascular (CV) event from the landmark REDUCE-IT cardiovascular outcomes trial have been accepted for presentation at the European Society of Cardiology (ESC) Congress, both online and onsite in Barcelona, August 26-29, 2022.

The accepted abstracts include a Late-Breaking Science presentation on reduction of ST-segment Elevation MI with VASCEPA from the REDUCE-IT trial. These and other new findings will be presented by a variety of international academic collaborators based on research or analyses supported by Amarin.

'We are pleased to support these Late Breaking Science and Oral Presentations at the upcoming ESC Congress being held later this month,' said Nabil Abadir, MB. CH.B., SVP, Chief Medical Officer and Head of Global Medical Affairs, Amarin. 'These data continue to underscore the clinical and therapeutic utility and value of VASCEPA/VAZKEPA and continue to validate the clinical outcomes shown in the overall REDUCE-IT trial. As we know, REDUCE-IT demonstrated the clear risk reduction benefits of icosapent ethyl in reducing cardiovascular events among patients most at risk for cardiovascular disease including those with previous cardiovascular events, such as myocardial infarction (MI) or stroke. We are proud of the continued work that is being done to further demonstrate the proven efficacy of VASCEPA in cardiovascular risk reduction while providing support to investigators to explore other ways in which VASCEPA can potentially help patients and impact public health.'

From our scientific research foundation 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, and Zug in Switzerland as well as commercial partners and suppliers around the world. We are committed to rethinking cardiovascular risk through the advancement of scientific understanding of the impact on society of significant residual risk that exists beyond traditional therapies, such as statins for cholesterol management.

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.3,4,5

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.6?The primary results of REDUCE-IT were published in?The New England Journal of Medicine?in November 2018.7?The total events results of REDUCE-IT were published in the?Journal of the American College of Cardiology?in March 2019.8?These and other publications can be found in the R&D section on the company's website at?www.amarincorp.com.

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, 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 18 million times. VASCEPA is covered by most major medical insurance plans. In addition to the United States, icosapent ethyl is approved and sold in Canada, Lebanon, Germany 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. The Great Britain Marketing Authorization for VAZKEPA applies to England, Scotland and Wales.
