Amarin is a neuroscience company focused on the development and commercialization of novel drugs for the treatment of neurological disorders affecting the central nervous system. Amarin's leading pipeline product, Miraxion, is in development for a number of therapeutic indications including Huntington's disease ("HD") and treatment-unresponsive depression. Amarin is listed on the Nasdaq small cap market (ticker: AMRN), has headquarters in London and a research and development facility in Stirling, Scotland. Corporate Strategy Amarin's goal is to capitalize on its strong reputation in neuroscience and to become a leader in the development and commercialization of novel drugs which address unmet medical needs. Amarin will develop its late-stage development pipeline initially focusing on HD and depression. Amarin will directly commercialize its neurology products in the U.S. and out-license or partner its product rights in Europe and Japan. Amarin will also out-license or partner its pipeline globally for indications outside neurology. Miraxion(TM) and Huntington's Disease Miraxion(TM), Amarin's lead late-stage development product, is being developed for the treatment of Huntington's disease, with phase III trials due to commence in early 2005. Miraxion for Huntington's disease has been granted Fast Track designation and received Orphan Drug designation both in the U.S. and in Europe. Huntington's disease is a genetic neurodegenerative disease characterized by movement disorder, dementia and psychiatric disturbance. It has been diagnosed in approximately 30,000 patients in the U.S. with a similar number in Europe. Additionally, over 200,000 persons in the U.S. alone are genetically "at risk" of developing the disease. Onset of symptoms is typically between 30-50 years of age with a typical life expectancy from diagnosis of 10-25 years. Patients with late stage disease require continuous nursing care, often in nursing homes, with an estimated annual cost to the U.S. economy of up to $2.5 billion. Presently, there is no effective treatment or cure for Huntington's disease. Miraxion and Treatment-Unresponsive Depression Phase II clinical trials have been conducted with Miraxion in treatment-unresponsive depression that concluded with statistical significance that a 1-gram per day dose of Miraxion was effective in treating depression in patients who remained depressed, despite receiving standard therapy. The results of two trials were published in the Archives of General Psychiatry in October 2002 and the American Journal of Psychiatry in March 2002. As a result of these encouraging clinical trial results, Amarin intends to further evaluate the clinical benefits of Miraxion in this indication and will seek a development and marketing partner to accelerate the program.
