Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

RATIONALE: Vaccines may make the body build an immune response to kill tumor cells.

PURPOSE: Phase I trial to study the effectiveness of vaccine therapy given with QS21 in treating patients who have progressive prostate cancer.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

OBJECTIVES: I. Determine the optimal dose of Thompson-Friedenreich \[TF(c)\]-keyhole limpet hemocyanin (KLH) conjugate plus adjuvant QS21 that induces an antibody response in patients with prostate cancer. II. Determine the safety of the TF(c)-KLH conjugate prepared using an MBS heterobifunctional linker plus QS21. III. Assess postimmunization changes in prostate specific antigen levels and other objective parameters of disease in these patients.

OUTLINE: This is a dose escalation study. Patients receive TF(c)-KLH conjugate with adjuvant QS21 subcutaneously weekly for 3 weeks, then once during weeks 7 and 19. Cohorts of 5 patients each receive escalating doses of TF(c)-KLH vaccine until the optimal dose, based on antibody response, is reached. Patients are followed monthly for 6 months, then every 3 months for 1 year.
