Press Releases

Aventis and Pfizer formed an Alliance in 1998 to jointly develop, manufacture and market an inhaled insulin, Exubera®. The contracts governing this Alliance contained change of control clauses which Pfizer chose to exercise following the acquisition of Aventis by Sanofi-Synthelabo.

Under the terms of the agreement signed today, sanofi-aventis will sell its share of the worldwide rights for the development, production and commercialization of Exubera® and its share of the Diabel joint-venture, a company based in Frankfurt, Germany, and owner of the production facility which manufactures the bulk insulin used in the production of Exubera®.

For the assets and rights transferred, sanofi-aventis will receive a payment of US $1.3 billion net of German local taxes. The completion of the transaction is subject to certain closing conditions, notably approval from the German anti-trust authorities, and is expected to occur in the first quarter of 2006.

Sanofi-aventis is the world’s third-largest pharmaceutical company, ranking number one in Europe.  Backed by a world-class R&D organization, sanofi-aventis is developing leading positions in seven major therapeutic areas: cardiovascular disease, thrombosis, oncology, metabolic diseases, central nervous system, internal medicine, and vaccines.  Sanofi-aventis is listed in Paris (EURONEXT: SAN) and in New York (NYSE: SNY).
