"We are very pleased to have Ferring as our partner, given the strength of their European specialty urology and endocrinology franchises, their existing commercial infrastructure across Europe, and the successful track record they have established in commercializing differentiated products in the European Union," said Armando Anido, Chief Executive Officer and President of Auxilium. "This agreement enables us to bring our innovative testosterone replacement product to patients in all of the 15 countries where Testim has been approved and potentially in additional new countries within Europe, thus expanding the reach of our Testim franchise outside the United States."

"Testim will be an excellent complement to our urology portfolio, where we already have Minirin(R) for primary nocturnal enuresis and hope to receive approval for our prostate cancer treatment, degarelix, in the first half of next year," commented Ferring's Chief Operating Officer, Michel Pettigrew. "It is a great pleasure to have cemented this partnership with Auxilium, with whom we share a commitment to the field of urology and a strong focus on patients."

Under the agreement, Auxilium will be responsible for manufacturing and supplying Testim to Ferring, while Ferring will be responsible for all regulatory, sales, marketing and distribution activities in Europe. Under the agreement with Ferring, Auxilium will receive a combination of upfront, milestone and royalty payments. Financial details of the agreement were not disclosed. Testim is currently approved for sale in 15 countries in Europe. The Company and Ipsen Pharma GmbH recently agreed to mutually terminate their distribution agreement for Testim in Europe and other countries outside North America and Japan.

About Testim

Testim is a novel, topical gel formulation that normalizes low levels of testosterone in men with hypogonadism, a condition that occurs when a man's body does not produce adequate amounts of testosterone. Men with hypogonadism or androgen deficiency may suffer from a decrease in energy, reduced muscle mass, an increase in abdominal fat, decline in libido, decreased sexual function, anemia, fatigue, depression and reduced bone density that may result in an increased risk of osteoporosis.

Testim was developed by Auxilium using a proprietary technology licensed from CPEX Pharmaceuticals, Inc. (NASDAQ: CPEX), and was launched in the U.S. by Auxilium's sales force in the first quarter of 2003. Auxilium received its first European regulatory approval for Testim in the UK in 2003 and currently has regulatory approval in 15 countries in Europe through the Mutual Recognition Procedure.

About Hypogonadism

A 2006 study that was published in The International Journal of Clinical Practice showed 39% of men over 45 years of age have low testosterone (total testosterone levels below 300 ng / dL). Hypogonadism is defined as reduced or absent secretion of testosterone which can lead to symptoms such as loss of libido, adverse changes in body composition, irritability and poor concentration. Auxilium research estimates that approximately 10% of men with hypogonadism currently receive TRT and that this low diagnosis rate stems primarily from low patient and physician awareness of the symptoms, treatment options and monitoring requirements
