This clinical trial is designed on the basis of an unmet clinical need, as well as other factors including: 1) a consensus among investigators on endpoints for studies of patients with a rising PSA, 2) the ability to identify subjects at high risk for developing radiographic metastases, 3) the fact that hormonal therapy has already been shown to improve survival when applied early in the natural history, and 4) the availability of chemotherapy such as docetaxel that can improve survival in subjects with advanced disease.
