  Purpose

RATIONALE: Drugs used in chemotherapy, such as docetaxel and prednisone, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Vatalanib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Giving vatalanib together with docetaxel and prednisone may kill more tumor cells.

PURPOSE: This phase I/II trial is studying the side effects and best dose of vatalanib when given together with docetaxel and prednisone and to see how well they work in treating patients with advanced prostate cancer.

Detailed Description:

OBJECTIVES:

Primary

  • Determine the dose-limiting toxicities and maximum tolerated dose of vatalanib when used in combination with docetaxel and prednisone in patients with chemotherapy-naive, metastatic, hormone-refractory prostate cancer. (phase I)

Secondary

  • Determine alterations in pharmacokinetics of docetaxel and vatalanib in these patients. (phase I)
  • Determine the clinical efficacy of this regimen as measured by declines in prostate-specific antigen, measurable disease response, time to progression, and overall survival. (phase II)

OUTLINE: This is a phase I open-label, dose-escalation study of vatalanib* followed by a phase II study.

  • Phase I: Patients receive docetaxel IV over 1 hour on day 2. Patients also receive oral prednisone twice daily and oral vatalanib once daily on days 1-21. Treatment repeats every 21 days in the absence of disease progression or unacceptable toxicity.
  • Cohorts of 3-6 patients receive escalating doses of vatalanib until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity.

NOTE: *Vatalanib is administered on days 5-21 during the first course only.

  • Phase II: Patients receive prednisone, docetaxel, and vatalanib at the MTD as in phase I. Treatment continues in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed periodically.

PROJECTED ACCRUAL: A total of 93 patients will be accrued for this study.

Criteria

DISEASE CHARACTERISTICS:

  • Histologically documented adenocarcinoma of the prostate

    • Measurable disease, defined as any lesion that can be accurately measured in at least 1 dimension ≥ 2 cm by conventional techniques or ≥ 1 cm by spiral CT scan or MRI

      • No PSA ≥ 5 ng/mL as only evidence of disease
    • PSA evidence for progressive prostate cancer consists of a PSA level ≥ 5 ng/mL that has risen on ≥ 2 successive occasions, ≥ 2 weeks apart
  • Castrate levels of testosterone (< 50 ng/dL) must be maintained

    • If no prior orchiectomy, patients must remain on testicular androgen suppression (e.g., with an LHRH analogue)
  • Patients receiving an antiandrogen as part of primary androgen ablation must demonstrate disease progression after discontinuation of antiandrogen

    • Disease progression after antiandrogen withdrawal is defined as 2 consecutive rising PSA values, obtained at least 2 weeks apart, or documented osseous or soft tissue progression

      • For patients receiving flutamide or megestrol acetate, at least 1 of the PSA values must be obtained 4 weeks or more after flutamide/megestrol acetate discontinuation
      • For patients receiving bicalutamide or nilutamide, at least 1 of the PSA values must be obtained 6 weeks or more after antiandrogen discontinuation
    • If improvement after antiandrogen withdrawal is noted, disease progression must be established
