Overview
Brief Summary
The purpose of this study is to look at patient outcomes when docetaxel is started prior to ADT with degarelix.
Detailed Description
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.

Arms & Interventions
Docetaxel + Degarelix
Docetaxel (TAXOTERE) will be given for up to 6 cycles every 21 days. During the 5th and 6th cycles, degarelix (Firmagon) will be administered on Cycle 5 day 1 and cycle 6 day 8. After cycle 6, degarelix will continue to be given every 28 days for a 5 more doses, for a total of 7 doses.
Intervention: Docetaxel
Docetaxel + Degarelix
Docetaxel (TAXOTERE) will be given for up to 6 cycles every 21 days. During the 5th and 6th cycles, degarelix (Firmagon) will be administered on Cycle 5 day 1 and cycle 6 day 8. After cycle 6, degarelix will continue to be given every 28 days for a 5 more doses, for a total of 7 doses.
Intervention: Degarelix
Outcomes
Primary Outcomes
PSA Response at 10 Months
Time Frame: 10 months
PSA complete response is defined as PSA level less than or equal to 0.2 ng/ml for two consecutive measurements at least three weeks apart. Date of complete response will be defined as the date of first recorded value less than 0.2 ng/ml. PSA progression will be defined as \> 25% increase from the PSA nadir (lowest PSA value recorded since trial enrollment) and \> 2 ng/dl above the nadir. Two consecutive increases must be recorded at least three weeks apart. Date of PSA progression will be defined as the first recorded PSA value that is a \> 25% increase from the PSA nadir and \> 2 ng/dl above the nadir.
Secondary Outcomes
- PSA Response at 6 Months(6 months)
- Number of Grade 3 and 4 Adverse Events Related to Docetaxel During First 4 Cycles(Up to 12 weeks (first 4 cycles of docetaxel))
- Frequency of Disease Progression at 12 Weeks Using PSA(12 weeks)
- PSA Response at 12 Weeks(12 weeks)
- Time to Development of Castration Resistance After Initiation With ADT(From initiation of Degarelix until disease progression or end of follow-up (up to 34 months))
- Progression Free Survival(34 months)
- Overall Survival (OS)(From trial enrollment until death or end of follow-up (up to 52.4 months))
