Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving more than one drug may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients who have prostate cancer that has not responded to hormone therapy.

Description:

OBJECTIVES: I. Determine the PSA response, duration of PSA response, disease free survival, median survival, and overall survival in patients with chemotherapy naive hormone refractory adenocarcinoma of the prostate treated with doxorubicin and cyclophosphamide with sequential docetaxel. II. Assess for any improvement in pain over time in patients treated with this regimen.

OUTLINE: This is a multicenter study. Patients receive doxorubicin IV over 3-5 minutes and cyclophosphamide IV on days 1, 22, 43, and 64, and docetaxel IV over 1 hour on days 85, 106, and 127 in the absence of disease progression or unacceptable toxicity. Patients receive filgrastim (G-CSF) subcutaneously daily beginning 24 hours after completion of chemotherapy infusions and continuing until blood counts recover. G-CSF must be discontinued at least 24 hours prior to starting subsequent chemotherapy infusions. Pain and analgesic use are assessed before study, every 3 weeks during study, after completion of study, and then at 3 months after completion of study. Patients are followed every 3 months for 2 years, every 6 months for 2 years, and then annually thereafter until death.

PROJECTED ACCRUAL: Approximately 42-105 patients will be accrued for this study over 18 months.
