OBJECTIVES:
* Compare immune response in patients with stage IIB-IV melanoma treated with vaccination comprising multiple synthetic melanoma peptides and Montanide ISA-51 with vs without sargramostim (GM-CSF).
* Compare immune response in patients treated with these vaccinations administered at 1 vs 2 sites.
OUTLINE: This is a randomized, open-label study. Patients are randomized to 1 of 4 treatment arms.
* Arm I: Patients receive vaccination comprising multiple synthetic melanoma peptides and Montanide ISA-51 at 1 injection site.
* Arm II: Patients receive vaccination comprising multiple synthetic melanoma peptides and Montanide ISA-51 at 2 injection sites.
* Arm III: Patients receive vaccination comprising multiple synthetic melanoma peptides, Montanide ISA-51, and sargramostim (GM-CSF) at 1 injection site.
* Arm IV: Patients receive vaccination comprising multiple synthetic melanoma peptides, Montanide ISA-51, and GM-CSF at 2 injection sites.
In all arms, treatment repeats once weekly for 6 weeks. Patients return for booster vaccinations at weeks 12, 26, 39, and 52.
PROJECTED ACCRUAL: A maximum of 124 patients will be accrued for this study.
