AMARIN ANNOUNCES COMMENCEMENT OF RECRUITMENT BY HUNTINGTON STUDY
GROUP FOR MIRAXION PHASE III CLINICAL TRIAL IN HUNTINGTON'S DISEASE 

LONDON, United Kingdom, June 14th, 2005 - Amarin Corporation plc
(NASDAQSC: AMRN) today announced that the Huntington Study Group ("HSG")
has commenced recruitment for the U.S. Phase III clinical trial of Miraxion(TM)
in Huntington's disease.

The HSG will be conducting a clinical study (TREND-HD) of ultra-pure ethyl-EPA
in persons 35 years of age or older who have mild to moderate Huntington's
disease. The HSG is a worldwide, not-for-profit group of physicians and other
clinical researchers who are experienced in the care of Huntington's disease
patients and dedicated to clinical research in Huntington's disease.

Huntington's disease is an inherited disease of the brain that usually begins
between the ages of 30 to 50, and includes motor, cognitive and behavioral signs
and symptoms. While there are medications to help relieve some of the disease
symptoms, there is no known treatment to slow the progression of Huntington's
disease, which affects about 30,000 people in North America.

Miraxion is thought to stabilize nerve cell membranes and improve neurological
functioning, although the exact mechanism of action is not currently known. An
earlier trial in subjects with Huntington's disease indicated that Miraxion at 2
grams daily was well tolerated over 12 months. This current trial is designed to
determine the effect of this daily dose of Miraxion on motor (movement) signs
and symptoms of Huntington's disease.

The current 12 month study includes a 6 month placebo controlled phase with
research subjects being randomly assigned to receive either Miraxion (2 grams
total daily dose) or a matching placebo. This will be followed by another 6
month observation phase in which all participants will receive Miraxion.
Researchers at 43 sites in the United States and Canada will each enroll
approximately 7-8 research subjects with early signs of Huntington's disease
who are independently ambulatory (walking) and fully self sufficient in
activities of daily living, such as eating, dressing and bathing.

There is no cost to participate in the study. Participants will be followed as
"out-patients" at regular intervals for 12 months. Individuals with mild to
moderate Huntington's disease who are interested in participating in this study
should visit the Huntington's Study Group website at: www.Huntington-Study-
Group.org or call the toll free number +1 (800) 487 7671.

Rick Stewart, chief executive officer of Amarin, commented; "commencement of
recruitment to the Phase III clinical trial for Miraxion is a major milestone
for Amarin. An immense amount of energy and dedication has been expended by all
involved to achieve this significant objective."
