AMARIN ANNOUNCES FDA ACCEPTANCE FOR FILING OF AMR101 NDA

AMARIN ANNOUNCES FDA ACCEPTANCE FOR FILING OF AMR101 NDA
BEDMINSTER, N.J. and DUBLIN, Ireland, Nov. 25, 2011 (GLOBE NEWSWIRE) -- Amarin Corporation plc (Nasdaq:AMRN), a late-stage biopharmaceutical company focused on cardiovascular disease, today announced that its New Drug Application (NDA) for AMR101 has been accepted for filing by the U.S. Food and Drug Administration (FDA). The acceptance of the NDA reflects the FDA's determination that the application is sufficiently complete to permit a substantive review.

"We are very pleased with the FDA's acceptance for filing of our AMR101 NDA submission as it is a significant achievement in the development of what we believe is a next generation Omega-3 based triglyceride lowering therapy," said Joseph S. Zakrzewski, Chairman and Chief Executive Officer of Amarin.

Amarin's NDA, submitted to FDA on September 26, 2011, seeks approval to market and sell AMR101 in the United States for the indication studied in the MARINE trial-the treatment of patients with very high triglycerides (≥500mg/dL). The NDA for AMR101 is supported by data from both Phase 3 AMR101 clinical trials, MARINE and ANCHOR, in which trials AMR101 achieved all of the primary endpoints and was well tolerated with a safety profile comparable to placebo.

The application will be subject to a standard review and will have a Prescription Drug User Fee Act (PDUFA) date of July 26, 2012. The PDUFA date is the goal date for the FDA to complete its review of the NDA.

About AMR101

AMR101 is a prescription-grade omega-3 fatty acid, comprising not less than 96% ultra pure EPA (icosapent ethyl), that Amarin is developing for the treatment of patients with very high triglyceride levels (≥500 mg/dL) and as a potentially first-in-class therapy for patients with high triglyceride levels (≥200 and <500mg/dL) who are also on statin therapy for elevated LDL-cholesterol levels (which we refer to as mixed dyslipidemia). Triglycerides are fats in the blood. Significant scientific and clinical evidence support the efficacy and safety of ethyl-EPA in reducing triglyceride levels and other important lipid and inflammation biomarkers, including Apo-B, non-HDL-C, Total-Cholesterol, VLDL-C, Lp-PLA2, and hs-CRP. AMR101 demonstrated a safety profile comparable to placebo in two completed Phase 3 clinical trials.

About Amarin

Amarin Corporation plc is a late-stage biopharmaceutical company with expertise in lipid science focused on the treatment of cardiovascular disease. The Company's lead product candidate is AMR101 (icosapent ethyl). Amarin reported positive, statistically significant top-line results for both of its two pivotal Phase 3 clinical trials, the MARINE trial (investigation of AMR101 as a treatment for patients with very high triglycerides [≥500 mg/dL]), as reported in November 2010, and the ANCHOR trial (investigation of AMR101 for the treatment of patients on statin therapy with high triglycerides [≥200 and <500mg/dL] with mixed dyslipidemia), as reported in April 2011. Both the MARINE and ANCHOR trials were conducted under Special Protocol Assessment (SPA) agreements with the U.S. Food and Drug Administration (FDA). Amarin also has next-generation lipid candidates under evaluation for preclinical development. In September 2011, Amarin submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) seeking approval for the marketing and sale of AMR101 for treatment of the patient population studied in the MARINE trial. Amarin plans to separately seek approval for the population studied in the ANCHOR trial after its REDUCE-IT cardiovascular outcomes trial is substantially underway. In August 2011, an SPA agreement with the FDA was reached for the REDUCE-IT cardiovascular outcomes study. The Company seeks to have this study substantially underway before the end of 2012.
