Purpose
The purpose of this study is to investigate a method of using dendritic cells (a kind of white blood cell) as a vaccine to stimulate your own immune system to react to your melanoma cells.

- To determine the immunological response based on measuring increased numbers of peptide specific CD8+ T cells as calculated by the tetramer assay. [ Time Frame: tumor response ] [ Designated as safety issue: No ]
- To determine the time to progression [ Time Frame: disease progression ] [ Designated as safety issue: No ]
- To assess regulatory T cell depletion after cyclophosphamide administration. [ Time Frame: 1 day ] [ Designated as safety issue: No ]
- To perform exploratory biomarker analysis of accessible tumors [ Time Frame: 1 day ] [ Designated as safety issue: No ]
- To determine the safety and side effect profile of mDC administered to patients given after a single dose of cyclophosphamide. [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
- To Assess the safety and tolerability of the mature dendritic cell vaccine [ Time Frame: 18 weeks ] [ Designated as safety issue: Yes ]

Experimental: 1
Blood mononuclear cells will be collected for vaccine production through apheresis. Patients will be given cyclophosphamide 300mg/m2 IV 3 days prior to vaccine dose #1 in order to deplete regulatory T cells. Patients will receive mature DC for each dose of vaccine and will receive autologous dendritic cells. The DC vaccine will be given intravenously every 3 weeks for a total of 6 doses. Peripheral blood will be taken weekly to monitor the immune response. Apheresis is repeated after vaccine dose #3 and dose #6 in order to collect PBMC for immune monitoring. Patients with stable disease or better after 6 doses will be eligible to receive additional vaccinations as maintenance therapy every 2 months until progression.

Detailed Description:
Eligible patients that provide written informed consent will undergo apheresis to collect blood mononuclear cells for vaccine production. All patients will be given cyclophosphamide 300mg/m2 IV three days prior to vaccine dose #1 in order to deplete regulatory T cells. All patients will receive mature DC for each dose of vaccine. For each dose all patients will receive autologous dendritic cells pulsed with 2 gp100 melanoma peptides (G209-2M and G280-9V) plus up to an additional 10 unique melanoma tumor-specific peptides. All patients will receive booster doses with mature DC. The DC vaccine will be given intravenously every three weeks for a total of six vaccine doses. Peripheral blood (16 ml) will be taken weekly to monitor the immune response to each peptide by tetramer assay. Apheresis is repeated after vaccine dose #3 and dose #6 in order to collect PBMC for immune monitoring. Restaging is performed after three and six vaccine doses. Patients with stable disease or better (partial response/complete response) after six doses will be eligible to receive additional vaccinations as maintenance therapy every 2 months until progression.
