Icosapent ethyl, a highly purified form of the ethyl ester of eicosapentaenoic acid, received unanimous backing from a Food and Drug Administration advisory panel for a new indication for reducing cardiovascular event risk.
Icosapent ethyl (Vascepa) received initial agency approval in 2012 for the indication of cutting triglyceride levels once they reached at least 500 mg/dL.
The target patient population for this new, cardiovascular-event protection role will reflect some or all of the types of patients enrolled in REDUCE-IT (Reduction of Cardiovascular Events with Icosapent Ethyl–Intervention Trial), which tested icosapent ethyl in 8,179 patients with either established cardiovascular disease or diabetes and at least one additional cardiovascular disease risk factor. This study provided the bulk of the data considered by the FDA panel.
REDUCE-IT showed that, during a median of 4.9 years, patients who received icosapent ethyl had a statistically significant 25% relative risk reduction in the trial’s primary, composite endpoint (New Engl J Med. 2019 Jan 3;380[1]:11-22).

Icosapent ethyl “appeared effective and safe,” and would be a “useful, new, added agent for treating patients” like those enrolled in the trial, said Kenneth D. Burman, MD, professor and chief of endocrinology at Medstar Washington (D.C.) Hospital Center and chair of the FDA’s Endocrinologic and Metabolic Drugs Advisory Committee.
The advisory panel members appeared uniformly comfortable with recommending that the FDA add a cardiovascular disease indication based on the REDUCE-IT findings.
But while they agreed that icosapent ethyl should receive some type of indication for cardiovascular event reduction, the committee split over which patients the indication should include. Specifically, they diverged on the issue of primary prevention.
Some said that the patient enrollment that produced a positive result in REDUCE-IT should not be retrospectively subdivided, while others said that combining secondary- and primary-prevention patients in a single large trial inappropriately lumped together patients who would be better considered separately.
Committee members also expressed uncertainty over the appropriate triglyceride level to warrant treatment. The REDUCE-IT trial was designed to enroll patients with triglycerides of 135 mg/dL or greater, but several panel members suggested that, for labeling, the threshold should be at least 150 mg/dL, or even 200 mg/dL.
Safety was another aspect that generated a lot of panel discussion throughout their day-long discussion, with particular focus on a signal of a small but concerning increased rate of incident atrial fibrillation among patients who received icosapent ethyl, as well as a small but nearly significant increase in the rate of serious bleeds.
Further analyses presented during the meeting showed that an increased bleeding rate linked with icosapent ethyl was focused in patients who concurrently received one or more antiplatelet drugs or an anticoagulant.
However, panel members rejected the notion that these safety concerns warranted a boxed warning, agreeing that it could be managed with appropriate labeling information.
Clinician reaction
Clinicians who manage these types of patients viewed the prospect of an expanded indication for icosapent ethyl as an important advance.
The REDUCE-IT results by themselves “were convincing” for patients with established cardiovascular disease without need for a confirmatory trial, Robert H. Eckel, MD, an endocrinologist and professor of medicine at the University of Colorado at Denver, Aurora, said in an interview. But he remained unconvinced about efficacy for primary-prevention patients, or even for secondary-prevention patients with a triglyceride level below 150 mg/dL.
“Icosapent ethyl will clearly be a mainstay for managing high-risk patients. It gives us another treatment option,” Yehuda Handelsman, MD, an endocrinologist and medical director and principal investigator of the Metabolic Institute of America in Tarzana, Calif., said in an interview. “I do not see the atrial fibrillation or bleeding effects as reasons not to approve this drug. It should be a precaution. Overall, icosapent ethyl is one of the easier drugs for patients to take.”
Dr. Handelsman said it would be unethical to run a confirmatory trial and randomize patients to placebo. “Another trial makes no sense,” he said.
But the data from REDUCE-IT were “not as convincing” for primary-prevention patients, suggesting a need for caution about using icosapent ethyl for patients without established cardiovascular disease, Paul S. Jellinger, MD, an endocrinologist in Fort Lauderdale, Fla., said in an interview.
Cost-effectiveness
An analysis of the cost-effectiveness of icosapent ethyl as used in REDUCE-IT showed that the drug fell into the rare category of being a “dominant” treatment, meaning that it both improved patient outcomes and reduced medical costs. William S. Weintraub, MD, will report findings from this analysis on Nov. 16, 2019, at the annual scientific sessions of the American Heart Association.
The analysis used a wholesale acquisition cost for a 1-day dosage of icosapent ethyl of $4.16, derived from a commercial source for prescription-drug pricing and actual hospitalization costs for the patients in the trial.
Based on the REDUCE-IT outcomes, treatment with icosapent ethyl was linked with a boost in quality-adjusted life-years that extrapolated to an average 0.26 increase during the full lifetime of REDUCE-IT participants, at a cost that averaged $1,284 less per treated patient over their lifetime, according to Dr. Weintraub, director of Outcomes Research at Medstar Washington Hospital Center, Washington.
Although the 0.26 lifetime increase in quality-adjusted life-years may sound modest, “in the cost-effectiveness world, 0.26 is actually significant,” Dr. Weintraub said. He also highlighted how unusual it is to find a patented drug that improves quality of life and longevity while also saving money.
“I know of no other on-patent, branded pharmaceutical that is dominant,” he said.
Off-patent pharmaceuticals, like statins, can be quite inexpensive and may also be dominant, he noted. Being dominant for cost-effectiveness means that icosapent ethyl “provides good value and is worth what we pay for it, well within social thresholds of willingness to pay,” Dr. Weintraub said.
REDUCE-IT was sponsored by Amarin, the company that markets icosapent ethyl (Vascepa). Dr. Burman has received research funding from AstraZeneca, Eisai, and IBSA. Dr. Eckel has received personal fees from Kowa Pharmaceuticals, Merck, Novartis, and Sanofi/Regeneron, as well as research funding from Endece, Ionis Pharmaceuticals, and UniQure. Dr. Handelsman has been a consultant to and received research funding from Amarin and several other companies. Dr. Jellinger has been a speaker on behalf of Amarin, Amgen, and Regeneron. Dr. Weintraub has received honoraria and research support from Amarin, and honoraria from AstraZeneca.
