ClinicalTrials.gov Identifier: | NCT00683670 |
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.
Condition | Intervention | Phase |
---|---|---|
Melanoma |
Drug: cyclophosphamide Biological: Mature dendritic cell vaccine |
Phase I Phase II |
Study Type: | Interventional |
Study Design: | Treatment, Open Label, Active Control, Single Group Assignment, Safety/Efficacy Study |

1: Experimental
mature dendritic cell vaccine and cyclophosphamide
|
Drug: cyclophosphamide
cyclophosphamide 300 mg/m2 IV over 1 hour on Day minus 3 of first dose of vaccine
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)

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 3 melanoma peptides (gp100 antigen) and one control (CMV) peptide. 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.
