Primary outcomePrimary: Cytotoxic T-cell Lymphocytes (CTL) Response Rate — 43; 47; 28; 5 percentage of participants — p=<0.001

Summary

RATIONALE: Vaccines made from peptides may make the body build an immune response to kill tumor cells. PURPOSE: This randomized phase II trial is studying four different vaccines using melanoma peptides from cytotoxic T cells and helper T cells to see how well they work in treating patients with metastatic melanoma.
