VASCEPA® (Icosapent Ethyl) Found to Significantly Reduce Cardiovascular Events in Patients with Compromised Renal Function at Baseline in Prespecified and Post Hoc Subgroup Analyses of Landmark REDUCE-IT® Study Presented at ASN Kidney Week 2020

• Patients with decreased renal function prior to treatment with VASCEPA or placebo had higher rates of cardiovascular events than the overall population studied in REDUCE-IT
• REDUCE-IT patients with decreased renal function prior to treatment showed similarly favorable relative risk reductions and numerically greater absolute risk reductions in cardiovascular events in comparison with the overall patient population
• Consistent and robust benefit in cardiovascular outcomes seen inboth prespecified and post hoc exploratory analysesacross a broad range of baseline eGFR (estimated Glomerular Filtration Rate) categories

DUBLIN, Ireland and BRIDGEWATER, N.J., Oct. 26, 2020 (GLOBE NEWSWIRE) -- Amarin Corporation plc (NASDAQ:AMRN) today announced the first presentation of REDUCE-IT® RENAL results at American Society of Nephrology (ASN) Kidney Week 2020, held virtually from October 22 – October 25. REDUCE-IT RENAL consisted of important prespecified and post hoc subgroup analyses of patients from the landmark REDUCE-IT cardiovascular outcomes study who had compromised renal function. The results of these analyses add to the growing body of knowledge on the clinical impact of VASCEPA® (icosapent ethyl) in at-risk patient populations. These new analyses, supported by Amarin, were presented by Arjun Majithia, M.D., Lahey Clinic.

“In the REDUCE-IT RENAL analyses we not only studied outcomes following icosapent ethyl administration, which were greatly improved, but equally importantly, we also examined the event rates in at-risk patients with compromised renal function, which clearly demonstrate that those patients urgently need additional solutions for cardiovascular risk reduction,” 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 and senior author of the REDUCE-IT RENAL analyses.

The REDUCE-IT RENAL analyses examined the full REDUCE-IT cardiovascular outcomes study patient population in prespecified and posthoc analyses across subgroups of eGFR categories. The primary endpoint (5-point major adverse cardiovascular events [MACE] consisting of non-fatal myocardial infarction [MI], stroke, cardiovascular death, unstable angina requiring hospitalization and coronary revascularization) and key secondary endpoint (3-point MACE consisting of non-fatal MI, stroke and cardiovascular death) events were consistently reduced when looking at data cut by prespecified baseline eGFR categories; eGFR <60 mL/min/1.73 m2 (n=1816), eGFR ≥60 to <90 mL/min/1.73 m² (n=4455), and eGFR ≥90 mL/min/1.73 m² (n=1902). Similar consistent cardiovascular risk reduction benefits were observed across post hoc analyses by finer cuts of eGFR categories. Primary and key secondary endpoint MACE rates increased with decreasing eGFR compared to the total patient population studied in REDUCE-IT, resulting in similarly favorable relative risk reductions and numerically greater absolute risk reductions with VASCEPA versus placebo in comparison with the overall patient population.

Adverse event rates were higher with decreasing eGFR, but total adverse events occurred at similar rates with VASCEPA versus placebo. A safety profile similar to the full REDUCE-IT study cohort was observed for VASCEPA compared with placebo across eGFR subgroups.

“We continue to see the consistency in benefit and safety of VASCEPA administration across various at-risk patient populations, including across varying degrees of renal function,” said Steven Ketchum, Ph.D., senior vice president and president, research & development and chief scientific officer, Amarin. “It is notable that, despite observing with REDUCE-IT patients the known increase in cardiovascular events with decreased kidney function, all patients experienced similar relative cardiovascular risk reduction benefits, resulting in overall greater absolute risk reductions in patients with compromised kidney function.”

“It is important to provide cardiovascular risk reduction solutions for patients with chronic kidney disease as data continue to highlight cardiovascular disease as an unfortunate and damaging comorbidity,” added Craig Granowitz, M.D., Ph.D., Amarin’s senior vice president and chief medical officer.

REDUCE-IT was not specifically powered to examine individual cardiovascular endpoints or patient subgroups, and urine samples were not collected during the REDUCE-IT study.

In addition to presentation of REDUCE-IT RENAL at ASN Kidney Week 2020, as previously reported, a separate presentation was made of real-world data analysis of U.S. veterans showing that increased triglyceride levels in patients with compromised renal function is a potential predictor of increased risk of cardiovascular events.

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%.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®(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.
