简要总结
RATIONALE: Calcitriol may help prostate cancer cells develop into normal cells. Zoledronate may delay or prevent the formation of bone metastases. Combining calcitriol and zoledronate may be an effective treatment for progressive prostate cancer.
PURPOSE: Phase I trial to study the effectiveness of combining calcitriol with zoledronate in treating patients who have progressive prostate cancer.
详细描述
OBJECTIVES:
- Determine the maximum tolerated dose of calcitriol administered with zoledronate in patients with progressive prostate cancer.
- Assess the effects of this regimen on calcium homeostasis and bone turnover in this patient population.
- Assess changes in PSA in patients treated with this regimen.
- Determine other antitumor effects of this regimen in these patients.
OUTLINE: This is a dose-escalation study of calcitriol.
Patients receive oral calcitriol weekly for 3 consecutive days and zoledronate IV monthly. Treatment continues in the absence of unacceptable toxicity or disease progression.
Cohorts of 3-6 patients receive escalating doses of calcitriol until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 3 of 6 patients experience dose-limiting toxicity.
