The filing was made by Elan Pharmaceuticals, Inc. (Elan), current holder of exclusive license rights to market and distribute Zelapar in the U.S. As previously announced, Amarin has an exclusive option to obtain the U.S. rights to Zelapar from Elan. Upon approval and exercise of the option, Zelapar will be marketed by Amarin Pharmaceuticals, Inc., the pharmaceutical development and marketing subsidiary of Amarin Corporation, plc. Zelapar, a novel and proprietary formulation of selegiline, an MAO-B inhibitor, is an oral tablet using the patented Zydis( r ) fast-dissolving technology of RP Scherer Corporation, Elan's licensor. Zelapar is being developed as adjunct treatment to levodopa for the symptoms of Parkinson's disease. Selegiline, the active ingredient in Zelapar, is approved for that indication in conventional tablet form. The Zelapar tablet dissolves in seconds and is absorbed in the tissues of the mouth, without swallowing or the need for liquids. "We believe that the convenience of Zelapar for Parkinson's patients, many of whom have trouble swallowing, combined with other unique advantages of the formulation, will make Zelapar an important new treatment option in addition to currently available therapies for Parkinson's," commented Rick Stewart, Amarin's chief executive officer. "Now that the NDA has been accepted for filing, we look forward to completion of the substantive review process by the FDA, and working toward approval of the NDA," he added. "On approval, Zelapar will complement our currently marketed Parkinson's disease product, Permax( r ) (pergolide mesylate tablets), progressing Amarin toward its goal of becoming a leader in the treatment of movement disorders," said Rick Stewart. Permax is a dopamine agonist indicated as adjunct treatment for the treatment of Parkinson's disease. The U.S. rights to Zelapar are currently licensed to Elan by R P Scherer Corporation, a unit of Cardinal Health. Elan will pay all research and development costs, including the costs of pursuing the NDA to approval. Amarin's option is exercisable at any time up to and for a period of time after any FDA approval of the NDA for Zelapar. An initial payment of $10 million would be made by Amarin upon the closing of the exercise of the option. The agreement provides for two additional milestone payments aggregating $27.5 million, contingent on achieving certain revenue levels, with a final milestone of $15 million payable eight years from exercise of the option. The final payment is subject to certain extension rights, and is also subject to certain reductions based on prior payments made. Amarin would also make royalty payments based on net sales of Zelapar in the U.S. If exercised, consummation of the option would be subject to customary closing conditions, including approval under the Hart- Scott-Rodino Antitrust Improvements Act. Amarin Corporation plc is a specialty pharmaceutical company focused on neurology and pain management. The Company plans to become a leader in these therapeutic categories by providing innovative products and solutions that address significant unmet medical needs.
