Combination Chemotherapy Plus Filgrastim in Treating Patients With Stage IV Prostate Cancer That Has Not Responded to Hormone Therapy

• Status: Completed
• Trial end date: 2006-06-01
• 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. Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy.

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

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

Details

• Lead Sponsor: Alliance for Clinical Trials in Oncology
• Collaborator: National Cancer Institute (NCI)
• Treatments: Carboplatin; Docetaxel; Estramustine; Hormones; Lenograstim
