Cellegy Pharmaceuticals Renegotiates Tostrex(R) EU License And Distribution Agreement With ProStrakan Group

HUNTINGDON VALLEY, Pa., Jan. 19 /PRNewswire-FirstCall/ -- Cellegy Pharmaceuticals, Inc. announced today that it has renegotiated its European Union license and distribution agreement for its product, Tostrex(R), with its licensee, ProStrakan Group plc. Tostrex is a 2% topical testosterone gel indicated for the treatment of male hypogonadism. In December 2004, the product was approved by the Swedish Medical Products Agency (MPA) for sale in Sweden.

Under the terms of the amended agreement, ProStrakan will assume responsibility for all manufacturing and other product support functions and will purchase the product directly from the manufacturer rather than purchasing from Cellegy under the terms of the original agreement. Cellegy will continue to receive milestones and royalties as set forth in the original agreement. Cellegy will benefit from reduced infrastructure costs by having its partner take over manufacturing responsibilities.

In July 2004, Cellegy and ProStrakan entered into an exclusive license agreement for the commercialization of Tostrex(R) (branded Fortigel(TM) in the United States) in Europe. In September 2005, the product was launched in Sweden, by ProStrakan. ProStrakan will be applying for further approvals of Tostrex throughout the European Union, under the Mutual Recognition Procedure.
