RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: Phase II trial to study the effectiveness of BMS-247550 in treating patients who have prostate cancer that has not responded to hormone therapy.

OBJECTIVES:

• Determine the prostate-specific antigen response to BMS-247550 in patients with hormone-refractory prostate cancer.
• Determine the overall survival and progression-free survival rate in patients treated with this drug.
• Determine the objective response rate (confirmed and unconfirmed complete and partial responses) in those patients with measurable disease treated with this drug.
• Evaluate the qualitative and quantitative toxic effects of this regimen in these patients.

OUTLINE: This is a multicenter study.

Patients receive BMS-247550 IV over 3 hours on day 1. Treatment repeats every 21 days in the absence of disease progression or unacceptable toxicity. Patients achieving a complete response (CR) receive 2 additional courses beyond CR.

Patients are followed every 3 months for 1 year and then every 6 months for 2 years.

PROJECTED ACCRUAL: A total of 25-45 patients will be accrued for this study within 5-9 months.
