WILMINGTON, Del., Sept. 22 /PRNewswire-FirstCall/ -- AstraZeneca today announced that the United States Food and Drug Administration (FDA) has granted an additional six-month period of exclusivity to market CASODEX(R) (bicalutamide) for its licensed advanced prostate cancer indication until April 1, 2009. AstraZeneca has been working with the FDA in the investigation of the safety and effectiveness of CASODEX in a pediatric setting but will not be seeking an indication in this population.
CASODEX is currently approved in the US at a dose of 50 mg daily tablet for use in combination with a luteinizing hormone-releasing hormone analog (LHRH-A) for the treatment of advanced prostate cancer (metastatic Stage D2).
AstraZeneca has a well-established prostate cancer portfolio including hormonal treatments CASODEX, launched in 1995, and ZOLADEX(R) (goserelin acetate implant), launched in 1989. Three Phase III clinical research trials (ENTHUSE program) are currently underway to evaluate the safety and effectiveness of an investigational compound, ZD4054, in non-metastatic and metastatic hormone-resistant prostate cancer.

About ZOLADEX(R) (goserelin acetate implant)
ZOLADEX 3.6 mg depot and 10.8 mg depot are prescription medications approved for use in combination with flutamide (an antiandrogen) plus radiotherapy for locally advanced prostate cancer. Treatment with the combination should start 8 weeks prior to starting and continue during radiation therapy.
ZOLADEX 3.6 mg depot and 10.8 mg depot are also approved to use alone for patients with advanced prostate cancer. ZOLADEX may help reduce the size of the cancer and reduce symptoms (palliative treatment).
Important Safety Information about ZOLADEX
ZOLADEX, like other luteinizing hormone-releasing hormone analogs (LHRH-As), may cause an initial rise in testosterone. When used alone, there may be a temporary worsening of prostate cancer symptoms at the start of therapy.
Common side effects that occurred during treatment with ZOLADEX (goserelin acetate implant) plus flutamide and radiation therapy or ZOLADEX alone included hot flashes, decrease in sexual desire and/or ability to have erections, diarrhea, pain (general, pelvic, and bone), lower urinary tract symptoms, fatigue, nausea, breast growth, swelling, rash, upper respiratory infection, and sweating.
