Marks first and only EC-approved treatment to reduce cardiovascular risk in high-risk, statin-treated adult patients who have elevated triglycerides (≥150 mg/dL) and other risk characteristics as studied in REDUCE-IT

^{® 1, 2}

DUBLIN, Ireland and BRIDGEWATER, N.J., March 30, 2021 (GLOBE NEWSWIRE) — Amarin Corporation plc (NASDAQ: AMRN) today announced that following a review and approval recommendation by the European Medicines Agency (EMA), the European Commission (EC) has approved the marketing authorization application for VAZKEPA (icosapent ethyl) to reduce the risk of cardiovascular events in high-risk, statin-treated adult patients who have elevated triglycerides (≥150 mg/dL) and either established cardiovascular disease or diabetes and at least one additional cardiovascular risk factor.

Amarin’s icosapent ethyl was approved for cardiovascular risk reduction by the U.S. Food and Drug Administration (FDA) in December 2019 and is marketed in the U.S. under the brand name, VASCEPA

.

“The approval of VAZKEPA marks a significant milestone for high-risk cardiovascular patients in Europe as it offers the first and only EC-approved therapy to reduce cardiovascular risk in high-risk statin-treated patients who have elevated triglycerides,” said Steven Ketchum, senior vice president, president of R&D and chief scientific officer of Amarin. “We look forward to launching VAZKEPA in Europe as it is an exciting opportunity for Amarin to make a difference in the lives of the many millions of patients throughout Europe who are at risk of a cardiovascular event.”

The EC approval for VAZKEPA is based on over a decade of development and testing of icosapent ethyl, including efficacy and safety data from the REDUCE-IT

^®

cardiovascular outcomes study.

²

REDUCE-IT evaluated more than 8,000 high risk patients who despite having their cholesterol levels well controlled by statin therapy remained at significant risk of heart attack, stroke, or other major adverse cardiovascular events (MACE), including death. As published, patients in the REDUCE-IT study had a median follow-up period of nearly five years. Results from this study, in which all patients remained treated with statins (and with other contemporary therapies) and where half the patients received icosapent ethyl and the other half received placebo, demonstrated a 25% relative risk reduction (p<0.001) in the first occurrence of MACE in the intent-to-treat patient population with use of icosapent ethyl (4 grams daily) compared with placebo.

“We are especially pleased to receive the EC’s approval of VAZKEPA to reduce cardiovascular risk as cardiovascular disease remains the number one cause of death in the European Union and its economic burden exceeds €210 billion per year

³

,” stated John F. Thero, president and chief executive officer. “We believe we are well positioned for a successful launch based on the high rate of cardiovascular events in Europe, the lack of an approved therapy for the indication VAZKEPA is positioned to address, and because of the demonstrated efficacy and safety profile of this unique drug.”

“Importantly, this EC approval provides ten years of market protection for VAZKEPA in the European Union. In addition, we have pending patent applications related to the REDUCE-IT study, which have the potential to extend exclusivity in Europe into 2039,” added Mr. Thero.

In anticipation of the commercial availability of VAZKEPA in Europe, the European Society of Cardiology and European Atherosclerosis Society updated its 2019 Dyslipidemia Management Guidelines to recommend the use of icosapent ethyl in high-risk, statin-treated patients.

⁴

Globally, there are 15 medical societies that recommend the use of icosapent ethyl in appropriate patients, emphasizing that the positive clinical results of the REDUCE-IT cardiovascular outcomes study should not be generalized to any product other than icosapent ethyl, and noting that the clinical results are unique to VASCEPA/VAZKEPA.

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.


⁵

The primary results of REDUCE-IT were published in

The New England Journal of Medicine

in November 2018.

²

The total events results of REDUCE-IT were published in the

Journal of the American College of Cardiology

in March 2019.

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, 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.
