VASCEPA® (Icosapent Ethyl) Found to Significantly Reduce Ischemic Events in Patients with Prior Coronary Artery Bypass Grafting (CABG) Procedures in Post Hoc Subgroup Analyses of Landmark REDUCE-IT® Study Presented at American Heart Association’s Virtual Scientific Sessions 2020

VASCEPA^®, compared with placebo, significantly reduced primary composite first and total major adverse cardiovascular events (MACE) in post hoc exploratory analyses of patients with a history of CABG by 24% and 36%, respectively, and key secondary composite first hard MACE, comprised of heart attacks, stroke and cardiovascular death, by 31%

Administration of VASCEPA resulted in robust absolute risk reductions of 6.2% and 6.0% and numbers needed to treat (NNT) of 16 and 17, respectively, for both primary and key secondary (hard MACE) composite endpoints in these subgroup analyses

Amarin to Webcast Discussion of Presented Data on November 18, 2020 at 4:30 p.m., Eastern Standard Time

DUBLIN, Ireland and BRIDGEWATER, N.J., Nov. 13, 2020 (GLOBE NEWSWIRE) — Amarin Corporation plc (NASDAQ:AMRN) today announced the presentation of REDUCE-IT^® CABG at American Heart Association’s (AHA) Virtual Scientific Sessions 2020, being held virtually from November 13 – November 17, 2020, adding to the growing body of knowledge on the clinical impact of VASCEPA^® (icosapent ethyl). These new analyses supported by Amarin were presented by Subodh Verma, M.D., Ph.D., FRCSC, Professor and Cardiac Surgeon at University of Toronto.

“The REDUCE-IT CABG analysis results are another piece of the puzzle when looking at the potential use of icosapent ethyl in the procedural setting,” commented Dr. Deepak L. Bhatt, M.D., M.P.H., Executive Director of Interventional Cardiovascular Programs at Brigham and Women’s Hospital and Professor of Medicine at Harvard Medical School, principal investigator of REDUCE-IT. “The findings of benefit in at-risk patients with prior CABG are consistent with previously presented data on overall reductions in first and total coronary revascularization events, as well as in patients with prior percutaneous coronary interventions, and further strengthen the case for consideration of icosapent ethyl as an additional intervention for use by physicians to care for this patient population.”

The REDUCE-IT CABG analysis examined 1,837 (22.5%) of the patients enrolled in REDUCE-IT, representing all patients who had undergone a prior coronary artery bypass grafting (CABG) procedure, a common form of surgical intervention to help treat coronary heart disease. Baseline characteristics were similar among patients randomized to VASCEPA versus placebo. Post hoc exploratory analyses of this subgroup showed that, for the composite endpoint of 5-point MACE, which was the prespecified primary endpoint for the full REDUCE-IT study cohort, time to first event was significantly reduced with VASCEPA versus placebo by 24% (p=0.004) and total (first and subsequent) events were also reduced by 36% (p=0.0002). For the REDUCE-IT study’s key secondary composite endpoint of 3-point MACE, time to first event was reduced by 31% (p=0.001) in the subgroup of patients with a prior CABG.

Coronary revascularization procedures, such as CABG, are invasive, carry multiple risks, and can have significant direct and indirect costs. Patients with elevated triglycerides despite statin therapy have increased risk for ischemic events, including coronary revascularizations. These procedures, whether pre-scheduled or performed in an emergency, inevitably result in additional time spent in a healthcare setting. The latest statistical update from the American Heart Association (AHA) shows that, in 2014, an estimated 371,000 inpatient CABG procedures were performed in the United States with a mean inpatient hospital charge for CABG of $168,541.¹

“Revascularization procedures overall significantly impact the healthcare system, with CABG procedures adding to the burden and driving substantial costs,” said Steven Ketchum, Ph.D., senior vice president and president, research & development and chief scientific officer, Amarin. “The subgroup data presented at AHA Virtual Scientific Sessions 2020 suggests another way in which VASCEPA can possibly alleviate the significant burden that at-risk patients and the healthcare system face with CABG procedures and how VASCEPA therapy can potentially reduce the risk of dangerous subsequent events.”  

REDUCE-IT was not specifically powered to examine individual cardiovascular endpoints or patient subgroups, therefore p-values presented for these revascularization analyses are nominal and exploratory with no adjustment for multiple comparisons. In addition, coronary revascularization as an endpoint can sometimes be considered subjective; however, these endpoints were adjudicated by an independent, blinded clinical endpoint committee. Results from the total coronary revascularization events analyses are consistent across the various recurrent event statistical models and are also consistent with the first coronary revascularization events results. Together, the REDUCE-IT first and total coronary revascularization events results support the robustness and consistency of the clinical benefit of VASCEPA therapy in reducing coronary revascularization.

These REDUCE-IT CABG results follow multiple scientific presentations of analysis results from other important patient subgroups in the REDUCE-IT study, including REDUCE-IT REVASC² and REDUCE-IT PCI.

About Cardiovascular Risk
The number of deaths in the United States attributed to cardiovascular disease continues to rise. There are 605,000 new and 200,000 recurrent heart attacks per year (approximately 1 every 40 seconds), in the United States. Stroke rates are 795,000 per year (approximately 1 every 40 seconds), accounting for 1 of every 19 U.S. deaths. Cardiovascular disease results in 859,000 deaths per year in the United States.¹ In aggregate, there are more than 2.4 million major adverse cardiovascular events per year from cardiovascular disease or, on average, one every 13 seconds in the United States alone.

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%.³ 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.^4,5,6

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.⁷ The primary results of REDUCE-IT were published in The New England Journal of Medicine in November 2018.⁸ The total events results of REDUCE-IT were published in the Journal of the American College of Cardiology in March 2019.⁹ These and other publications can be found in the R&D section on the company’s website at www.amarincorp.com.

About VASCEPA^®(icosapent ethyl) Capsules
VASCEPA (icosapent ethyl) capsules are the first-and-only prescription treatment approved by the FDA comprised solely of the active ingredient, icosapent ethyl (IPE), a unique form of eicosapentaenoic acid. 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 eight million times. VASCEPA is covered by most major medical insurance plans. The new, cardiovascular risk indication for VASCEPA was approved by the FDA in December 2019.

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.
