Amarin Announces Agreement From FDA On Special Protocol Assessment For Amr101 Outcomes Study

Study Positions AMR101 to Potentially Address Patient Populations of More Than 70 Million in the U.S. Alone

MYSTIC, Conn. and DUBLIN, Ireland, Aug. 10, 2011 (GLOBE NEWSWIRE) -- Amarin Corporation plc (Nasdaq:AMRN), a clinical-stage biopharmaceutical company with a focus on cardiovascular disease, today announced that it has reached agreement with the U.S. Food and Drug Administration (FDA) on a Special Protocol Assessment (SPA) agreement for the design of the previously described cardiovascular outcomes study of AMR101 formally titled REDUCE-IT (Reduction of Cardiovascular Events with EPA - Intervention Trial). Amarin previously announced that it achieved the primary endpoints of two Phase 3 studies of AMR101, both of which were conducted under separate SPAs.

In REDUCE-IT, Amarin will evaluate the effectiveness of AMR101 in reducing the first major cardiovascular events in an at-risk patient population. The control arm of the study will be patients on optimized statin therapy. The active arm of the study will be patients on optimized statin therapy plus AMR101. All subjects enrolled in the study will have elevated triglyceride levels and either coronary heart disease or risk factors for coronary heart disease. Amarin will be responsible for the study which will be conducted internationally. The Company will use an experienced clinical research organization (CRO) to help manage the study and is in the late stages of contract negotiations with a leading CRO for that purpose.

Consistent with prior comments, Amarin estimates that the study will require approximately 8,000 patients and take approximately 6 years for completion. The Company anticipates that if, as intended, it commences Outcomes study activities in 2011 that it will be positioned to achieve approximately 50% enrollment before the end of 2012.

Once REDUCE-IT is substantially underway, the Company believes that it will have met all of the requirements to request approval of AMR101 for treating the mixed dyslipidemia patient population studied in the ANCHOR trial. AMR101 is positioned to be the first drug in its class approved for treatment of this indication. Upon completing REDUCE-IT, and assuming a successful result, Amarin anticipates being able to pursue an indication for the prevention of cardiovascular events; this population is estimated to be greater than twice the size of the combined indications studied in the MARINE and ANCHOR trials. The Company also anticipates that, similar to ANCHOR, a significant number of the patients in REDUCE-IT will have diabetes.

"We are delighted to have finalized the protocol for REDUCE-IT and to have the FDA agree to this via a Special Protocol Assessment, our third SPA for AMR101, which is remarkable," stated Joseph Zakrzewski, Amarin's Executive Chairman and CEO. "Based on the strong safety profile of AMR101, our positive Phase 3 results for AMR101 and success in Japan with an outcomes study of highly pure EPA, we believe that REDUCE-IT is positioned for success." Mr. Zakrzewski added, "The design of REDUCE-IT reflects the diligent evaluation of numerous other outcome studies by our clinical team, advisors and other interested parties all of whom are commended and thanked for their contributions to the very direct and efficient design of this study."
