Vaccine Therapy Plus Interleukin-12 in Treating Patients With Metastatic Prostate Cancer That Has Not Responded to Hormone Therapy

Phase 2
Completed
Conditions
Prostate Cancer
Interventions
Biological: PSA prostate cancer vaccine
Biological: recombinant interleukin-12
Registration Number
NCT00015977
Lead Sponsor
University of Chicago
Brief Summary

RATIONALE: Vaccines made from a patient's white blood cells may make the body build an immune response to kill cancer cells. Interleukin-12 may kill cancer cells by stopping blood flow to the tumor and by stimulating a person's white blood cells to kill cancer cells. Combining vaccine therapy with interleukin-12 may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of vaccine therapy combined with interleukin-12 in treating patients who have metastatic prostate cancer that has not responded to hormone therapy.

Detailed Description

OBJECTIVES:

* Determine whether immunization with prostate-specific membrane antigen-pulsed autologous peripheral blood mononuclear cells and interleukin-12 can promote specific T-cell priming in patients with metastatic hormone-refractory prostate cancer.

* Determine the clinical response in patients treated with this regimen.

OUTLINE: Patients receive prostate-specific membrane antigen-pulsed autologous peripheral blood mononuclear cells subcutaneously (SC) on day 1 and interleukin-12 SC on days 1, 3, and 5. Treatment repeats every 21 days for 3-9 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months.

PROJECTED ACCRUAL: A total of 12-37 patients will be accrued for this study within 37 weeks.
