Amarin Informed by FDA of October 16th Advisory Committee Date in Connection
With Supplemental New Drug Application (sNDA) for Vascepa(R) in the Treatment
of Patients With High Triglycerides (>200 mg/dL and

Submission for Indication Studied in the ANCHOR Phase 3 Clinical Trial Under
Special Protocol Assessment Agreement With FDA

BEDMINSTER, N.J. and DUBLIN, Ireland, June 19, 2013 (GLOBE NEWSWIRE) -- Amarin
Corporation plc (Nasdaq:AMRN), a biopharmaceutical company focused on the
commercialization and development of therapeutics to improve cardiovascular
health, announced today that it was informed yesterday by the U.S. Food and
Drug Administration (FDA) that the FDA will convene an advisory committee on
October 16, 2013 in connection with the FDA's review of the Supplemental New
Drug Application (sNDA) seeking approval for the use of Vascepa® (icosapent
ethyl) capsules as an adjunct to diet in the treatment of adult patients with
high triglycerides (TG ≥200 mg/dL and <500 mg/dL) with mixed dyslipidemia. The
FDA has previously assigned a Prescription Drug User Fee Act (PDUFA) date of
December 20, 2013 for completion of its review of the sNDA.The FDA will
consider the recommendation of the advisory committee, but the final decision
regarding the approval of the sNDA will be made by the FDA.

"ANCHOR clinical trial results demonstrated the important role EPA-only
omega-3 can play in helping adult patients with high triglycerides and mixed
dyslipidemia," said Christie M. Ballantyne, M.D., Baylor College of Medicine
and the Methodist DeBakey Heart and Vascular Center, Houston, Texas, and
principal investigator of the ANCHOR trial. "In the ANCHOR trial, Vascepa
lowered high triglyceride levels and showed robust reductions in a broad range
of other lipid parameters on top of optimized statin therapy compared to
placebo. Importantly, these beneficial effects were seen with a safety and
tolerability profile comparable to placebo."

Vascepa was approved in 2012 as an adjunct to diet to reduce triglyceride
levels in adult patients with severe (≥500 mg/dL) hypertriglyceridemia, based
on the results of Amarin's MARINE clinical trial.The safety data from both
the MARINE and ANCHOR clinical trials were reviewed by the FDA as part of the
approval of Vascepa in the MARINE indication and are reflected in the approved
product labeling for Vascepa.As is customary practice at FDA, yesterday's
notification from the FDA is the only communication confirming the need for
such a meeting.The FDA advisory committee topics and questions to the
committee are anticipated to be made public by the FDA on its website in the
week preceding the meeting, consistent with FDA procedure.

"For key first-in-class indications, an FDA advisory committee meeting is
expected, and this public forum will be an important opportunity to discuss
the ANCHOR data, which demonstrated Vascepa's unique potential as an adjunct
to diet in the treatment of adult patients with high triglycerides (TG 200-499
mg/dL) and mixed dyslipidemia," said Eliot A. Brinton, MD, FAHA, FNLA,
Director of Atherometabolic Research, Utah Foundation for Biomedical Research,
and President, American Board of Clinical Lipidology. "Currently, many of
these patients are receiving another prescription omega-3 which is not
indicated for this disorder.Having instead an omega-3 product which lowers
LDL-cholesterol in addition to triglycerides, has tolerability comparable to
placebo, and is FDA-approved for use on top of statin therapy would be a
welcome addition to the physician's armamentarium for comprehensive lipid
management."

"With the support of the Amarin team, including our outside consultants, such
as Christie and Eliot, we look forward to the advisory panel and working with
the FDA to obtain regulatory approval of Vascepa for ANCHOR this year," said
Joseph Zakrzewski, Chairman and Chief Executive Officer of Amarin. 

Currently, Amarin only markets Vascepa for the MARINE indication, for which it
was approved in 2012, and which includes approximately 4 million patients in
the United States.The proposed ANCHOR indication would expand the Vascepa
patient population to include adult patients on statin therapy with
triglyceride levels ranging from 200 to 499 mg/dL (and mixed
dyslipidemia).Amarin estimates that one in five, or nearly 40 million, U.S.
adults have triglyceride levels in this range.Amarin began selling Vascepa on
January 28, 2013. Amarin believes that many of the same clinicians who have
prescribed Vascepa for its currently approved indication will prescribe
Vascepa for the much broader indication, based on the ANCHOR study now under
formal FDA review, if approved.
