The litigation concerns two U.S. patents licensed to Amarin by Eli Lilly and Company (NYSE: LLY) upon Amarin's acquisition from Elan Corporation (NYSE: ELN) of the exclusive U.S. license rights to Permax (r) (pergolide mesylate) tablets. In return for a sublicense under those patents, Amarin will receive royalty payments from Ivax's sale of any pergolide products, as described below. "We are very pleased to resolve this litigation on terms which acknowledge the value of our licensed patents," commented Rick Stewart, Amarin's chief executive officer. "Settling this litigation will allow us to focus our resources and efforts on progressing our pipeline products, Zelapar ( tm )(selegiline orally disintegrating tablets) and LAX-101 (ethyl eicosapentaenoate)," he added. Under the terms of the settlement, Amarin and Lilly will grant to Ivax a non-exclusive sublicense in the U.S. under the two patents at issue, beginning September 2, 2003, and continuing for the remaining life of the patents. In return, Ivax will make royalty payments to Amarin, to be shared between Amarin and Lilly, from the first six months' gross profit (net sales less cost of goods sold) from sales of any Ivax pergolide product under its Abbreviated New Drug Application (ANDA) for pergolide products, once approved by FDA. The patent litigation was initiated by Elan in 2001 upon the filing by Ivax of its ANDA, and was assumed by Amarin as a part of its acquisition of the U.S. license rights from Elan. Under the Hatch-Waxman law regarding patent rights and approval of generic drugs, Elan's commencement of the patent suit resulted in an automatic stay of approval of Ivax's ANDA by the Food and Drug Administration (FDA) until September 2003. Ivax has announced that its ANDA has received tentative approval by the FDA. Pergolide is the active pharmaceutical ingredient in Permax, indicated as adjunctive treatment for Parkinson's disease. An ANDA for pergolide products has previously been filed by Teva Pharmaceuticals (Nasdaq: TVA) and approved by FDA. Teva's product was commercially launched in January of this year. Amarin is not aware of any other ANDA for pergolide filed with FDA. Amarin Corporation plc is a specialty pharmaceutical company focused on neurology. The Company plans to become a leader in this therapeutic category by providing innovative products and solutions that address significant unmet medical needs. Amarin has eleven pharmaceutical products on the U.S. market along with a development pipeline that includes two late-stage candidates: Zelapar ( tm ) (selegiline orally disintegrating tablets), for Parkinson's disease, and LAX-101, a proprietary compound for Huntington's Disease.
