Vaccine Therapy in Treating Patients With Stage III or Stage IV Melanoma

OBJECTIVES:

• Compare the efficacy of vaccination with autologous dendritic cells pulsed with tumor and influenza antigen peptides treated with vs without ex vivo CD40-ligand, in terms of tumor-specific T-cell response, in patients with HLA-A1 and/or HLA-A2.1 positive stage III or IV melanoma.
• Determine the safety and tolerability of these vaccinations in these patients.
• Determine tumor response and recurrence rates in patients treated with these vaccinations.

OUTLINE: This is an open-label non-randomized study.

• Phase I: Patients undergo leukapheresis for collection of peripheral blood mononuclear cells (PBMC). PBMC are cultured with sargramostim (GM-CSF) and interleukin-4 to generate dendritic cells (DCs) on day -9. DCs are pulsed separately with HLA-A1 and HLA-A2.1-restricted flu matrix peptides derived from melanoma-associated tumor antigens (MAGE-10.A2, Melan-A, MAGE-3, NY-ESO-1, gp100 antigen, and tyrosinase peptide). Half of the DCs are treated ex vivo with CD40-ligand. Patients receive the peptide-pulsed DC vaccinations subcutaneously (SC) on days 1, 14, 42, and 70 in the absence of disease progression.

Patients who show tumor response (at least stable disease) at day 98 progress to phase II of the study.

• Phase II: Patients undergo leukapheresis as in phase I on days 102, 352, and 688. Patients receive up to 6 additional booster vaccinations SC as in phase I on days 126, 184, 268, 356, 520, and 692.

Patients are followed for 10 years.
