  Purpose

RATIONALE: Androgens can stimulate the growth of prostate cancer cells. Estramustine may fight prostate cancer by reducing the production of androgens. Exisulind may stop the growth of prostate cancer by stopping blood flow to the tumor. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining these therapies may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of combining estramustine with exisulind and docetaxel in treating patients who have metastatic prostate cancer that has not responded to hormone therapy.

Arms Assigned Interventions
Experimental: Combined chemotherapy
combination of 3 chemotherapy agents for hormone refractory prostate cancer
Drug: docetaxel
70 mg/sq m IV infusion over 1 hour Day 2 of ea cycle

Drug: exisulind
Two 125 mg capsules PO bid Days 1-21 of ea cycle

Detailed Description:

OBJECTIVES:

  • Determine the time to objective and biochemical progression and response proportion (objective and post-therapy changes in PSA) in patients with hormone refractory metastatic prostate cancer treated with docetaxel, estramustine, and exisulind.
  • Determine the toxic effects of this regimen in these patients.
  • Determine the overall survival of patients treated with this regimen.

OUTLINE: Patients receive oral estramustine 3 times daily on days 1-5, docetaxel IV over 1 hour on day 2, and oral exisulind twice daily on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months for 2 years.

PROJECTED ACCRUAL: A total of 72 patients will be accrued for this study within 18 months.

Criteria

DISEASE CHARACTERISTICS:

  • Histologically confirmed adenocarcinoma of the prostate

    • Progressive systemic (metastatic) disease despite castrate levels of testosterone secondary to orchiectomy or luteinizing hormone-releasing hormone (LHRH) agonist therapy

      • Castrate levels of testosterone must be maintained
      • LHRH analog therapy should be continued
    • Failed prior standard androgen-deprivation therapy

  • Evidence of metastatic disease on CT scan, MRI, or bone scan (no positron-emission tomography or prostascint)
  • Evidence of progressive disease after most recent prior therapy (including hormonal therapy) as defined by 1 of the following:

    • Measurable disease progression

      • More than 20% increase in the sum of the longest diameters of target lesions from the time of maximal regression or the appearance of 1 or more new lesions
    • Bone scan progression

      • Appearance of 1 or more new lesions on bone scan attributable to prostate cancer AND
      • PSA at least 5 ng/mL
    • PSA progression

      • PSA at least 5 ng/mL which has increased serially from baseline on 2 occasions (at least 1 week apart) NOTE: If the confirmatory PSA is less than screening PSA, an additional test for rising PSA is required
