Combination Chemotherapy With Ketoconazole in Treating Patients With Prostate Cancer

• Status: Completed
• Trial end date: 2002-11-01
• Target enrollment: 0
• Participant gender: Male

Summary

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

PURPOSE: Randomized phase II trial to study the effectiveness of combination chemotherapy consisting of paclitaxel, etoposide, and estramustine as compared with ketoconazole plus doxorubicin, vinblastine, and estramustine in treating patients with prostate cancer.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: M.D. Anderson Cancer Center
• Collaborator: National Cancer Institute (NCI)
• Treatments: Albumin-Bound Paclitaxel; Doxorubicin; Estramustine; Etoposide; Etoposide phosphate; Ketoconazole; Liposomal doxorubicin; Paclitaxel; Vinblastine
