  Purpose

RATIONALE: Drugs used in chemotherapy, such as ixabepilone and estramustine, use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether BMS-247550 is more effective with or without estramustine in treating prostate cancer.

PURPOSE: This randomized phase I/II trial is studying the best dose of ixabepilone when given together with estramustine and to see how well giving ixabepilone together with estramustine works compared to ixabepilone alone in treating patients with progressive prostate cancer.

Detailed Description:

OBJECTIVES:

  • Determine the maximum tolerated dose of ixabepilone combined with estramustine in patients with progressive androgen-independent adenocarcinoma of the prostate. (Phase I)
  • Compare the safety and efficacy of ixabepilone with or without estramustine in this patient population. (Phase II)
  • Correlate the clinical outcomes with reverse transcriptase-polymerase chain reaction-based assay for prostate-specific antigen mRNA in patients treated with these regimens.

OUTLINE: This is a dose-escalation study of ixabepilone (phase I) followed by a randomized, multicenter study (phase II).

  • Phase I: Patients receive ixabepilone IV over 3 hours on day 2 and oral estramustine 3 times daily on days 1-5. Courses repeat every 3 weeks in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of ixabepilone until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 6 patients experience dose-limiting toxicity.

  • Phase II: Patients are randomized to 1 of 2 treatment arms.

    • Arm I: Patients receive ixabepilone IV over 3 hours at the MTD on day 2 and estramustine as in phase I.
    • Arm II: Patients receive ixabepilone IV over 3 hours at the MTD on day 1. Treatment in both arms repeats as in phase I.

Patients are followed every 12 weeks until disease progression.

PROJECTED ACCRUAL: A total of 3-12 patients will be accrued for phase I of this study and a total of 44-92 patients (22-46 per treatment arm) will be accrued for phase II of this study within 12-18 months.

  Eligibility

Criteria

DISEASE CHARACTERISTICS:
