Amarin Completes Target Patient Enrollment in North American Phase III Trial of Miraxion(TM) in Huntington's Disease

LONDON, June 29 (HSMN NewsFeed) -- Amarin Corporation plc (NASDAQ: AMRN ) today announced that it has successfully achieved target patient enrollment in the North American Phase III clinical trial of Miraxion in Huntington's disease (HD).

The target of three hundred randomized patients with HD in the TREND study, which is being conducted by the Huntington Study Group (HSG) at 42 neurology centers in the U.S. and Canada, has been met. The trial is evaluating the effects of Miraxion compared to placebo using the Total Motor Score-4 (TMS-4) subscale of the Unified Huntington's Disease Rating Scale (UHDRS). It is hoped that patients treated with Miraxion at a dose of 2 grams per day (1 gram twice daily) for 6 months will demonstrate significant improvements in their motor functioning as measured by TMS-4. Motor dysfunction is a prominent and progressively deteriorating feature of HD, an ultimately fatal genetic disease causing uncontrolled movements, loss of intellectual faculties, emotional disturbances, psychosis and dementia. Currently, there are limited treatment options for HD patients. There is no specifically approved treatment in the US to prevent the symptoms of HD or to delay its progression. Earlier studies of Miraxion showed encouraging improvements in motor function in HD patients.

Rick Stewart, Chief Executive Officer of Amarin, commented: "Enrolling 300 individuals in this U.S. and Canadian Phase III trial is an enormous achievement for Amarin. With over 540 patients, the combined U.S., Canadian and European trials form one of the largest therapeutic programs ever conducted in HD. The support and involvement of the HSG has been instrumental to our success in meeting our enrollment target for such a large trial within nine months. We look forward to completing the treatment phase of this trial by year end and eagerly await its clinical result."

Miraxion has Orphan Drug designation in both the U.S. and Europe and has Fast-Track designation from the FDA for review of the New Drug Application for HD. The Phase III trials are being conducted under a Special Protocol Assessment (SPA), a process under which the FDA provides evaluation and guidance on clinical trial protocols for Phase III trials involving designated Orphan Drugs.

The Huntington Study Group (, based at the University of Rochester, is a non-profit group of leading physicians and other health care providers from medical centres in the U.S., Canada, Europe and Australia, experienced in the care of HD patients and dedicated to clinical research in HD.

"The European Phase III clinical trial of Miraxion in HD was initiated three months after the U.S. study and remains on schedule for full patient enrollment by late summer," concluded Mr. Stewart.
