Vaccine Therapy Plus QS21 in Treating Patients With Progressive Prostate Cancer
RATIONALE: Vaccines may make the body build an immune response to kill tumor cells.
PURPOSE: Phase II trial to study the effectiveness of vaccine therapy given with QS21 in treating patients who have progressive prostate cancer.

|Official Title:||Vaccination of Prostate Cancer Patients With MUC-2-KLH Conjugate Plus the Immunological Adjuvant QS21: A Trial Examining the Immunogenicity of Glycosylated MUC-2-KLH Peptide Conjugate Vaccine|
|Study Start Date:||September 1999|
|Study Completion Date:||June 2008|
|Primary Completion Date:||June 2008 (Final data collection date for primary outcome measure)|
Patients receive vaccination with glycosylated MUC-2 antigen with keyhole limpet hemocyanin conjugate subcutaneously (SQ) plus immunological adjuvant QS21 SQ on weeks 1-3, 7, 15, and 27 for a total of 6 vaccinations. Patients are followed every 3 months for 1 year or until disease progression.
|Biological: MUC-2-KLH vaccine Biological: QS21|
OBJECTIVES: I. Determine if immunization with glycosylated MUC-2 antigen with keyhole limpet hemocyanin (KLH) conjugate plus immunological adjuvant QS21 induces an antibody, helper T cell, and/or cytotoxic T cell response against glycosylated MUC-2 in patients with progressive prostate cancer. II. Determine the safety of this treatment regimen in this patient population. III. Determine the effect of glycosylated MUC-2 antigen with KLH conjugate on the T cell response against MUC-2 and by skin testing in these patients. IV. Assess the post immunization changes in prostate specific antigen levels and other objective parameters of disease including radionuclide bone scan and/or measurable disease in these patients.
OUTLINE: Patients receive vaccination with glycosylated MUC-2 antigen with keyhole limpet hemocyanin conjugate subcutaneously (SQ) plus immunological adjuvant QS21 SQ on weeks 1-3, 7, 15, and 27 for a total of 6 vaccinations. Patients are followed every 3 months for 1 year or until disease progression.
PROJECTED ACCRUAL: A total of 3-15 patients will be accrued for this study within 1 year.
