Primary Outcome Measures:
  • 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 ]

Secondary Outcome Measures:
  • 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 ]

Arms Assigned Interventions
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.
Drug: cyclophosphamide
cyclophosphamide 300 mg/m2 IV over 1 hour on Day minus 3 of first dose of vaccine
Other Name: Cytoxan
Biological: Mature dendritic cell vaccine
Mature dendritic 15 million/peptide, 60 million total IV over 30 minutes (first dose)
Biological: Mature dendritic cell vaccine
mature dendritic cell booster dose X5 (q3 weeks) (5 million/peptide, 20 million total)

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.
