Calcitriol and Dexamethasone in Treating Patients With Prostate Cancer Who Have Undergone Surgery or Radiation Therapy

Phase 2
Completed
Conditions
Prostate Cancer
Registration Number
NCT00054522
Lead Sponsor
Roswell Park Cancer Institute
Brief Summary

RATIONALE: Calcitriol may help tumor cells develop into normal cells. Dexamethasone may increase the effectiveness of calcitriol by making tumor cells more sensitive to the drug.

PURPOSE: Phase II trial to study the effectiveness of combining calcitriol with dexamethasone in treating patients with prostate cancer who have undergone surgery or radiation therapy.

Detailed Description

OBJECTIVES:

* Determine whether calcitriol and dexamethasone can slow the rise in prostate-specific antigen (PSA) levels in patients with early, recurrent prostate cancer after prior radical prostatectomy or radiotherapy.

* Determine the safety of this regimen in these patients.

* Determine the utility of serum PSA in monitoring the therapeutic effect of calcitriol in these patients.

OUTLINE: Patients are stratified according to prior therapy (radical prostatectomy vs radiotherapy).

Patients receive oral calcitriol once daily on days 1-3 alone on week 1. Beginning on week 3, patients receive calcitriol as in week 1 and oral dexamethasone on days 0-4. Courses repeat every 2 weeks in the absence of disease progression or unacceptable toxicity.

PROJECTED ACCRUAL: A total of 56 patients (28 per stratum) will be accrued for this study.
