Update from Endo Pharmaceuticals regarding its New Drug Application for FORTESTA

Endo Pharmaceuticals (Nasdaq: ENDP) today announced that it received a Complete Response letter from the U.S. Food and Drug Administration (FDA) regarding the New Drug Application (NDA) for FORTESTA(TM) (testosterone) 2% Gel for men diagnosed with low testosterone (Low T), also known as hypogonadism.

"The potential of this action was considered in the structure of the deal to in-license this product," said Dr. Ivan Gergel, M.D., executive vice president, R&D, Endo Pharmaceuticals. "We will continue to work closely with the FDA to address their questions and we expect to file a complete response, mid-2010. Endo is committed to bringing FORTESTA to market to offer men another option for testosterone replacement therapy."

In August 2009, Endo signed an agreement with U.K.-based ProStrakan Group Plc to acquire exclusive U.S. rights to commercialize the testosterone 2% gel, branded variously as Tostran, Tostrex and Itnogen outside the U.S. The testosterone 2% gel is marketed across Europe by ProStrakan's own, in-house sales forces and is out-licensed by ProStrakan to Bayer Schering Pharma (BSP) in 147 countries.
