AMARIN ANNOUNCES COMPLETION OF U.S. INVESTIGATORS' MEETING FOR
UPCOMING MIRAXION PHASE III CLINICAL TRIAL IN HUNTINGTON'S DISEASE 

LONDON, United Kingdom, June 9th, 2005 - Amarin Corporation plc
(NASDAQSC: AMRN) today announced the completion of the U.S.
investigators' meeting for the upcoming U.S. phase III clinical trial of
Miraxion(TM) for the treatment of the symptoms of Huntington's disease.

Investigators and coordinators from the 43 selected Huntington's Study
Group ("HSG") clinical trial sites attended the meeting in Philadelphia.
The objective of the meeting was orientation and training about specific
aspects of the clinical trial design. The clinical investigators who attended
the meeting comprised leading Huntington's disease experts in the U.S.

The Miraxion Huntington's disease clinical trial in the U.S. will have
approximately 300 patients in a double blind placebo controlled study over a
six month period. At the end of the six month period, all patients on placebo
will be switched to active Miraxion for a further six month phase. It is
expected that the trial will commence in July. A second European phase III
clinical trial with approximately 240 patients is expected to commence in
the third quarter of 2005.

Miraxion is a novel drug for the treatment of Huntington's disease which showed
encouraging results in an earlier phase III clinical trial in 135 patients at
six clinical trial sites in the U.S. and internationally. 

Rick Stewart, chief executive officer of Amarin, commented "The successful
completion of the investigators' meeting marks another significant step towards
the commencement of the Miraxion phase III clinical trial in Huntington's
disease. We are grateful to all the investigators and coordinators who attended
the meeting and look forward to the commencement of the trial."
