Dendritic Cells (White Blood Cells) Vaccination for Advanced Melanoma
This trial is active, not recruiting.
|Treatments||cyclophosphamide, mature dendritic cell vaccine|
|Sponsor||Abramson Cancer Center of the University of Pennsylvania|
|Start date||August 2008|
|End date||February 2017|
|Trial size||17 participants|
|Trial identifier||NCT00683670, 07-0652 / 201103308|
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|
|Principal investigator||Gerald P. Linette, M.D., Ph.D.|
|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.|
