Trial Information

Vaccination of Prostate Cancer Patients With Thompson-Friedenreich [TF(c)]-KLH Conjugate Plus the Immunological Adjuvant QS21: A Trial Comparing TF(c)-KLH Doses


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.
