DHA-Paclitaxel in Treating Patients With Metastatic Prostate Cancer

Study Overview
=================
Brief 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 DHA-paclitaxel in treating patients who have metastatic prostate cancer that has not responded to hormone therapy.

Detailed Description
-----------------
OBJECTIVES: Determine the objective tumor response rate or prostate-specific antigen response, duration of response, and time to disease progression in patients with metastatic hormone-refractory prostate cancer treated with DHA-paclitaxel. Determine the overall survival of patients treated with this drug. Determine the toxicity profile of this drug in these patients. Assess the quality of life of patients treated with this drug. OUTLINE: This is a multicenter study. Patients receive DHA-paclitaxel IV over 2 hours on day 1. Treatment repeats every 21 days in the absence of disease progression or unacceptable toxicity. Quality of life is assessed at baseline, every 2 courses, and off study. Patients are followed every 3 months. PROJECTED ACCRUAL: A total of 18-50 patients will be accrued for this study.
