About Amarin
Amarin is a clinical-stage biopharmaceutical company focused on cardiovascular disease. The Company’s lead candidate is AMR101, a prescription grade omega-3 product comprising not less than 96% ultra-pure ethyl eicosapentaenoic acid (EPA-E). Amarin is preparing to commence two Phase 3 clinical trials for AMR101 targeting the treatment of hypertriglyceridemia. These trials will be conducted under Special Protocol Assessment (SPA) agreements with the U.S. Food and Drug Administration (FDA). It is estimated that as many as 28 million people in the U.S. alone have elevated blood triglyceride levels, a major risk factor for cardiovascular morbidity and mortality. In addition, Amarin has potential next-generation lipid candidates under evaluation for preclinical development. Amarin recently established its research and development headquarters in Mystic, Connecticut, USA and engaged Medpace as CRO for the Phase 3 trials. In addition to its cardiovascular development focus, Amarin has non-core programs available for partnering in the area of central nervous system (CNS) disorders, including Huntington’s disease, myasthenia gravis and Parkinson’s disease.
