Vaccination of Prostate Cancer Patients With MUC-2-KLH Conjugate Plus the Immunological Adjuvant QS21

"The MUC-2-KLH conjugate will be administered subcutaneously to random sites on the upper arm and upper leg at weekly intervals for 3 weeks. This will be followed by a 4 week break and then a fourth vaccination during week 7, and 3 months later during week 19. Booster vaccinations may be given at or after week 50 and 100, and every 6 months thereafter to select patients who show no evidence of radiographic disease progression.~After 5 patients have been enrolled and completed two vaccinations without Grade II or greater toxicity, we will proceed to the next higher dose level. No dose escalations will be performed in the same patient."
