RNS Number:3820E Amarin Corporation Plc 24 September 2007 AMARIN ANNOUNCES PUBLICATION OF PRE-CLINICAL MEMORY DATA IN JOURNAL OF NEUROCHEMISTRY Pre-Clinical Study Results For Memory and Cognition Validate Clinical Development Program LONDON, United Kingdom, September 24, 2007 - Amarin Corporation plc (NASDAQ: AMRN) ("Amarin" or "Company") announced that the results of a pre-clinical program in memory and cognition using ultra-pure eicosapentanoic acid (EPA) have been published in the "Journal of Neurochemistry" (Minogue AM et al 2007 J. Neurochem. 10.1111/j.1471-4159.2007.04848.x) in an article entitled, "Modulation of amyloid-ss-induced and age-associated changes in rat hippocampus by eicosapentaenoic acid." The preclinical study was conducted by Professor Marina Lynch, Department of Physiology, Institute of Neuroscience, Trinity College, Dublin, and demonstrated that EPA attenuates the age-related and b amyloid-induced impairment of Long Term Potentiation (LTP). LTP is a phenomenon considered an important marker of the integrity of neural processes involved in memory and cognition. This mechanism was identified by Professor Eric Kandel as fundamental in mediating memory and cognition and, consequently, LTP is considered a major mechanism by which the brain learns and maintains memories. The study confirmed that EPA reduced concentrations of the pro-inflammatory interleukin 1b (IL-b), and phosphorylation of the stress-activated protein kinase, c-jun N-terminal kinase (JNK). These factors are associated with inhibition of LTP thus potentially impair memory and cognition. Commenting on the study, Professor Lynch said, "These findings identify an important potential role for EPA in modulating ss-amyloid-induced and age-related changes in the brain and the present findings suggest that the beneficial effects of EPA are likely to result from its attenuation of hippocampal IL-1ss concentration, perhaps as a consequence of its action on expression of PPARg." Rick Stewart, Chief Executive Officer of Amarin, commented, "These findings are very encouraging and provide the validation to proceed with our clinical development program using EPA for Age Associated Memory Impairment and cognition. They are especially important as the findings reinforce the substantial body of pre-clinical work already undertaken. We expect to commence a clinical program in Age Associated Memory Impairment by year-end." About the Role of EPA in Long-Term Potentiation (LTP), Age Associated Memory Impairment (AAMI) and Cognition Aging is associated with impairment in LTP, resulting in Age Associated Memory Impairment (AAMI) and cognitive function. This impairment results from inflammatory and oxidative changes in the hippocampal area of the brain. In pre-clinical studies, analysis of the mechanisms underlying the effect of aging on hippocampal function has focused to a significant extent on analysis of age-related changes in long-term potentiation (LTP) in the hippocampus. Further, these findings support the substantial preclinical studies previously published in the use of EPA to promote LTP in aging models.
