Latest analysis shows VASCEPA(R) (icosapent ethyl) significantly lowered the risk of potentially fatal cardiovascular events in patients with prior percutaneous coronary intervention

Last Updated on March 10, 2022 by GlobeNewsWire

A new post hoc sub-analysis of the landmark REDUCE-IT Study, published in the Journal of the American Heart Association (JAHA), found VASCEPA(R) significantly reduced the risk of cardiovascular death, strokes, heart attacks, coronary revascularization, and unstable angina by 34% in patients with a history of percutaneous coronary intervention (PCI).(1)

Icosapent ethyl resulted in robust absolute risk reductions of 8.5% and 5.4% and numbers needed to treat (NNT) of 12 and 19, respectively, for the primary and key secondary composite endpoints.(1)

DUBLIN, Ireland and BRIDGEWATER, N.J., March 10, 2022 (GLOBE NEWSWIRE) — Amarin Corporation plc (NASDAQ:AMRN) today announced the publication of new REDUCE-IT data analysis that helps support the clinical benefits of icosapent ethyl (IPE) for patients who have received a percutaneous coronary intervention (PCI) and are at high risk for experiencing a stroke, heart attack, or fatal cardiovascular (CV) event.(1)

Percutaneous coronary interventions (also known as coronary angioplasty, which can include stent insertion) are medical procedures used to open coronary arteries, the main blood vessels supplying the heart, that are narrowed or blocked by a build-up of atherosclerotic plaque.(2) The heart needs a constant supply of oxygenated blood to function effectively; if the coronary arteries become narrowed and restricted, this can lead to serious heart health complications such as angina or a heart attack.(3)

The REDUCE-IT Prior PCI study was a post hoc sub-analysis published in the Journal of the American Heart Association (JAHA). This publication furthers the clinical evidence base for icosapent ethyl treatment in patients with prior PCI at risk of a recurrent CV event.

There were 3,408 patients who had undergone a prior PCI (41.7% of the initial REDUCE-IT study population). The median time after PCI for these patients was 2.9 years. Baseline characteristics were similar among patients randomised to icosapent ethyl versus placebo. Of those patients with prior PCI included in the sub-analysis receiving standard of care treatment only, 37.6% experienced a major CV event (cardiovascular death, myocardial infarction, stroke, coronary revascularization, or unstable angina requiring hospitalization), compared with 25.6% of patients receiving icosapent ethyl.(1)

In patients with a history of PCI, icosapent ethyl treatment versus placebo reduced the first primary composite endpoint of CV death, non-fatal myocardial infarction (MI) (heart attack), non-fatal stroke, coronary revascularization, or unstable angina, by 34% (absolute risk reduction of 8.5%, HR 0.66; 95% CI, 0.58-0.76; p<0.001); number needed to treat (NNT) =12) and the total events (first and subsequent) by 39% (RR 0.61; 95% CI, 0.52-0.72; p<0.001).(1)

Icosapent ethyl also led to a 34% reduction in the key secondary composite endpoint of CV death, non-fatal MI, or non-fatal stroke versus placebo (absolute risk reduction 5.4%, HR 0.66; 95% CI, 0.56-0.79, p<0.001; NNT=19). The sub-analysis also showed that icosapent ethyl treatment led to a 40% risk reduction of repeat coronary revascularization versus placebo (absolute risk reduction 7.7%, HR 0.60; 95% CI, 0.51-0.70; p<0.001) in patients who have previously undergone PCI.(1)

Safety findings in the REDUCE-IT Prior PCI subgroup were consistent with the full study cohort.(1)

The REDUCE-IT study enrolled 8,179 patients for a median of 4.9 years, who were all receiving a stable dose of a statin for at least 4 weeks. All patients had controlled low-density lipoprotein cholesterol (LDL-C), elevated triglyceride levels, and were either 45 years of age or older, with established cardiovascular disease (CVD), or were 50 years of age or older, with diabetes and other cardiovascular risk factors.(4)

It is important to note that the exploratory nature limited this post hoc analysis. Other limitations noted by the authors include that REDUCE-IT was not powered for sub-group analyses and all P values should be considered hypothesis-generating.

Commenting on the paper’s findings, 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 Prior PCI analyses, said:

“This analysis from REDUCE-IT highlights the benefits of icosapent ethyl in patients with elevated triglycerides and a history of prior PCI, a commonly performed procedure. The findings of benefit in at-risk patients with prior PCI are consistent with previously published coronary revascularization data demonstrating reductions in first and total coronary revascularization events of 34% and 36%, respectively, in the overall REDUCE-IT population.”(5)

Dr. Bhatt continued, “Patients on standard of care treatment who nevertheless have elevated triglycerides are at high-risk for recurrent CV events. Icosapent ethyl has the potential to benefit a large proportion of these patients, including those with a history of prior PCI.”(1)

There is evidence suggesting that patients who have a prior PCI are at a heightened risk of subsequent CV events compared with other patients with CV risk factors.(1) In recent years, efforts to improve stent design, LDL-C, inflammation, and platelet activity have reduced repeat events among patients who undergo coronary stenting.(1)

Yet, many patients still experience recurrent events, especially those with diabetes mellitus and elevated triglycerides.(1) This suggests there may be a need for additional treatments and interventions to reduce this remaining risk.

Karim Mikhail, Amarin’s president and chief executive officer, commented, “We continue to gain new insights into the important role that IPE can play in helping patients with CVD; especially for those most vulnerable to a serious or fatal event. This latest analysis showed that IPE lowered the risk of heart attack, stroke or cardiovascular death for patients with a prior PCI — offering additional evidence that our product can be a vital contributor in reducing harm and deaths from cardiovascular disease around the world.”

The REDUCE-IT PCI subgroup analysis was funded by Amarin. Dr. Bhatt receives research funding from Amarin that goes to Brigham and Women’s Hospital.

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 yeari 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%.ii 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.iii,iv,v

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.vi The primary results of REDUCE-IT were published in The New England Journal of Medicine in November 2018.vii The total events results of REDUCE-IT were published in the Journal of the American College of Cardiology in March 2019.viii These and other publications can be found in the R&D section on the company’s website at www.amarincorp.com.

About VASCEPA(R) (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, 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.

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 ordiabetes 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.

Key clinical effects of VASCEPA on major adverse cardiovascular events are included in the Clinical Studies section of the prescribing information for VASCEPA as set forth below:
