Clinical Trial Summary

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 DX-8951f in treating patients who have metastatic prostate cancer that has not responded to hormone therapy.

Description:

OBJECTIVES: I. Determine the antitumor activity of DX-8951f as measured by PSA response in patients with hormone refractory prostate cancer. II. Determine the antitumor activity of this drug in the subpopulation of these patients with measurable disease. III. Evaluate the quantitative and qualitative toxicities of this drug in these patients. IV. Evaluate the pharmacokinetics of this drug in these patients.

OUTLINE: This is a multicenter study. Patients receive DX-8951f IV over 30 minutes daily for 5 days. Courses repeat every 21 days. Treatment continues in the absence of unacceptable toxicity or disease progression. Patients with no evidence of PSA decrease by the start of course 3 receive no further treatment. Patients are followed every 3 months until death.

PROJECTED ACCRUAL: A total of 12-37 patients will be accrued for this study.
