Study Overview
Brief 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.
Detailed Description
OBJECTIVES:
- Compare the cytotoxic T-cell response to each of 12 melanoma peptides restricted by Human Leukocyte Antigen (HLA)-A1, -A2, or -A3 in patients with metastatic melanoma vaccinated with or without these 12 melanoma peptides and with or without helper peptides.
- Compare the helper T-cell response to each of 6 melanoma helper peptides restricted by HLA-DR molecules in patients treated with these vaccinations.
- Determine whether the addition of 6 melanoma helper peptides to a vaccine containing multiple class I Major histocompatibility complex (MHC)-restricted peptides augments T-cell responses to the class I restricted peptides in these patients.
- Determine, preliminarily, whether booster vaccination maintains immune response in patients treated with these vaccinations.
- Compare the rates of clinical response and survival in patients treated with these vaccinations.
- Determine, preliminarily, whether cellular immune response correlates with clinical response and survival rates in patients treated with these vaccinations.
OUTLINE: This is a randomized, multicenter study. Patients are stratified according to HLA type (HLA-A1 vs HLA-A2 vs HLA-A1 and -A2 vs HLA-A3) and planned sentinel immunized node biopsy (yes vs no). Patients are randomized to 1 of 4 treatment arms.
- Arm I: Patients receive 2 injections of multi-epitope peptide vaccine comprising 12 melanoma peptides restricted by Class I MHC (12MP) emulsified with sargramostim (Granulocyte-macrophage colony-stimulating factor, GM-CSF) and Montanide ISA-51 or Montanide ISA-51 VG (ISA-51) intradermally (ID) and subcutaneously (SC) on day 1 of weeks 1-3 and 1 injection at the primary site only on day 1 of weeks 5-7.
- Arm II: Patients receive 2 injections of multi-epitope peptide vaccine comprising 12MP and 1 tetanus helper peptide emulsified with GM-CSF and ISA-51 ID and SC on day 1 of weeks 1-3 and 1 injection at the primary site only on day 1 of weeks 5-7.
- Arm III (closed to accrual as of 5/19/08): Patients receive 2 injections of multi-epitope peptide vaccine comprising 12MP and 6 melanoma helper peptides (6HP) emulsified with GM-CSF and ISA-51 ID and SC on day 1 of weeks 1-3 and 1 injection at the primary site only on day 1 of weeks 5-7.
- Arm IV: Patients receive 2 injections of multi-epitope peptide vaccine comprising 6HP emulsified with GM-CSF and ISA-51 ID and SC on day 1 of weeks 1-3 and 1 injection at the primary site only on day 1 of weeks 5-7.
In all arms, patients continue therapy in the absence of unacceptable toxicity or disease progression necessitating other urgent therapy.
