Ketoconazole, Hydrocortisone, and GM-CSF in Treating Patients With Progressive Prostate Cancer After Hormone Therapy
RATIONALE: Androgens can cause the growth of prostate cancer cells. Drugs, such as ketoconazole, may stop the adrenal glands from making androgens. GM-CSF may help ketoconazole work better by making tumor cells more sensitive to the drug. Giving ketoconazole together with hydrocortisone and GM-CSF may be an effective treatment for prostate cancer.
PURPOSE: This phase II trial is studying how well giving ketoconazole together with hydrocortisone and GM-CSF works in treating patients with progressive prostate cancer after hormone therapy.
Drug: therapeutic hydrocortisone

- Time to progression [ Designated as safety issue: No ]
- Response rate as measured by prostate-specific antigen and objective parameters [ Designated as safety issue: No ]
- Frequency of grades 3-4 toxicity [ Designated as safety issue: Yes ]
- Pattern of immune response as measured by immunohistochemistry [ Designated as safety issue: No ]

- Evaluate the effect of ketoconazole, hydrocortisone, and sargramostim (GM-CSF) on time to clinical progression in patients with prostate cancer that has progressed on primary hormonal therapy.
- Evaluate the objective response frequency in patients treated with this regimen.
- Investigate the safety of this regimen.
OUTLINE: This is an open-label, nonrandomized study.
Patients receive oral ketoconazole three times daily and oral hydrocortisone twice daily on days 1-28 and sargramostim (GM-CSF) subcutaneously on days 15-28. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.
PROJECTED ACCRUAL: A total of 48 patients will be accrued for this study.
