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.

| Official Title: | Mature Dendritic Cell Vaccination Against gp100 in Patients With Advanced Melanoma |
- To determine the immunological response based on measuring increased numbers of peptide specific CD8+ T cells as calculated by the tetramer assay. [ Time Frame: Through completion of treatment ] [ Designated as safety issue: No ]Starting on Day 0, two tubes will be drawn weekly until Day 64. Thereafter, two tubes will be drawn every 21 days until Day 190. For patients receiving maintenance treatment, blood is drawn every month.
- Assess the safety and tolerability of the mature dendritic cell vaccine [ Time Frame: 30 days after end of treatment ] [ Designated as safety issue: Yes ]
- To determine the time to progression [ Time Frame: Through completion of treatment or until progressive disease ] [ Designated as safety issue: No ]
- To assess regulatory T cell depletion after cyclophosphamide administration. [ Time Frame: Day -3 (72 hours prior to vaccine dose 1) ] [ Designated as safety issue: No ]
- To perform exploratory biomarker analysis of accessible tumors [ Time Frame: Baseline ] [ 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: Day 0 (prior to vaccine dose 1) ] [ Designated as safety issue: Yes ]
- Determine the clinical response rate using RECIST criteria [ Time Frame: After third vaccine, sixth vaccine, and then every 8 weeks ] [ Designated as safety issue: No ]

Experimental: Dendritic Cell Vaccine (First Group)
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.
