OUTLINE: This is a randomized, open-label study. Patients are randomized to 1 of 6 treatment arms: Arm I: Patients receive peptide 946 melanoma vaccine (peptide 946) emulsified with QS21 subcutaneously (SQ). Arm II: Patients receive peptide 946 emulsified with Montanide ISA-51 (ISA-51) SQ. Arm III: Patients receive peptide 946 combined with tetanus peptide melanoma vaccine (tetanus peptide) emulsified with QS21 SQ. Arm IV: Patients receive peptide 946 combined with tetanus peptide emulsified with ISA-51 SQ. Arm V: Patients receive peptide 946-tetanus peptide conjugate emulsified with QS21 SQ. Arm VI: Patients receive peptide 946-tetanus peptide conjugate emulsified with ISA-51 SQ. Initially, 4 patients are randomized to Arm I and 4 patients are randomized to Arm II. If no dose limiting toxicities are observed in these patients, then additional patients are randomized to arms III-VI. Patients in each arm receive vaccine on day 0 and at months 1, 2, 3, 6, 9, and 12. Patients are followed at 6 and 12 months.
