Phase II Study of Docetaxel Before Degarelix in Patients With Newly Diagnosed Metastatic Prostate Cancer.

This study will look at two drugs, docetaxel and degarelix, which are both FDA approved for the treatment of prostate cancer. Docetaxel is a standard chemotherapy treatment for metastatic prostate cancer. Degarelix is an androgen deprivation therapy (ADT) agent that decreases the amount of testosterone in the body, which helps to fight tumor growth. Usually, docetaxel is given after ADT. This study will look at how your cancer changes when docetaxel is started before ADT. You are being asked to participate in this study because you have metastatic prostate cancer that can be treated with docetaxel and ADT.
