Endo Pharmaceuticals (Nasdaq: ENDP) announced that the U.S. Food and Drug Administration (FDA) has approved FORTESTA Gel for the treatment of low testosterone, or 'Low T,' also known as hypogonadism. Symptoms associated with Low T include erectile dysfunction and decreased sexual desire, fatigue and loss of energy, mood depression, regression of secondary sexual characteristics and osteoporosis. Low T is a condition that has an estimated prevalence in nearly 14 million men in the United States, yet only about 1.3 million, (9 percent) are currently being treated. Endo Pharmaceuticals expects to introduce FORTESTA™ Gel in the United States in early 2011.

"Declining blood levels of testosterone can occur in men beginning as early as age 40. The symptoms of low testosterone can be non-specific and often associated with other chronic medical problems," said Adrian Dobs, M.D., M.H.S., professor of medicine and oncology, Johns Hopkins University School of Medicine, Division of Endocrinology and Metabolism in Baltimore, Md., and principal investigator of the FORTESTA Gel Phase III clinical trial. "FORTESTA Gel is an important new treatment option for men who are diagnosed with low testosterone."

FORTESTA Gel is a clear, colorless, odorless gel that is gently applied with one finger to the front and inner thighs, and not the upper body. FORTESTA Gel comes in a metered-dose pump that delivers the correct dose per complete depression. Patients using FORTESTA Gel should apply the product as directed. Safety and efficacy of FORTESTA Gel in males less than 18 years old have not been established.

"The approval of FORTESTA™ Gel reinforces our commitment to men's health by providing an important new treatment option for millions of men with Low T," said David Holveck, chief executive officer, Endo Pharmaceuticals.

In a 90-day, multicenter, open-label, non-comparative, pivotal Phase III trial involving men with hypogonadism, 78 percent of patients using FORTESTA™ Gel had an average serum total testosterone concentration within the normal range at day 90. The most common side effect in this trial was application site reactions.

Important Safety Information for FORTESTA gel

To lower the risk of transfer of FORTESTA Gel from your body to others, you should: Apply FORTESTA Gel only to the front and inside area of your thighs that will be covered by clothing and wash your hands right away with soap and water after applying FORTESTA Gel. After the gel has dried, cover the application area with clothing and keep the area covered until you have washed the application area well or have showered. If you expect another person to have skin-to-skin contact with your thighs, first wash the application area well with soap and water.

Stop using FORTESTA Gel and call your healthcare provider right away if you see any signs and symptoms in a child or a woman that may have occurred through accidental exposure to FORTESTA Gel.
