°®¶¹´«Ã½. (Headquarters: Tokyo, CEO: Haruo Naito, “Eisai”) announced today that its U.S. subsidiary Eisai Inc. has entered into an agreement to divest its U.S. and Puerto Rican rights for the antiepileptic agent Zonegran® (zonisamide) to Concordia Pharmaceuticals Inc. (Concordia), a subsidiary of Concordia Healthcare Corp. (Headquarters: Ontario, CEO: Mark Thompson).

Zonegran is an antiepileptic drug (AED) originally created by Dainippon Pharmaceutical Co., Ltd. (currently Sumitomo Dainippon Pharma Co., Ltd.), for which Eisai and its U.S. subsidiary hold exclusive rights in Europe, North America and Asia. Under this agreement, Eisai Inc. will sell its commercialization rights associated with Zonegran in the U.S. and Puerto Rico to Concordia. In addition, the companies have agreed to enter into a supply agreement under which Eisai Inc. will serve as Concordia's supplier of Zonegran for the U.S. and Puerto Rican market. The closing of the transaction is subject to certain regulatory approvals and Sumitomo Dainippon Pharma Co., Ltd.'s consent.
Eisai will retain its rights to Zonegran outside of the U.S. and Puerto Rico, and continue to distribute the product in licensed territories such as Europe.

Eisai believes that this divestiture agreement with Concordia will lead to maximization of the agent's product and patient value in the U.S. and Puerto Rico. In addition, the agreement will enable Eisai to strategically reallocate resources to other mid-to-long-term business growth areas so as to continue to make further contributions to address the diversified needs of, and increase the benefits provided to, patients and their families.
