-
leukapheresis step
Patients will undergo leukapheresis.
-
leukapheresis step
Leukapheresis will be performed on the following day.
-
leukapheresis step
A HLA-A2 positive healthy donor undergoes leukapheresis.
-
material component separation step
CD8 T cells are purified using MACS cell separation.
-
isolation of cell population step
PBMC are isolated from buffy coats by density gradient centrifugation using Biocoll (BIOCHROM).
-
injection step
-
injection step
Patients receive V administrations with eventual additional ones depending on clinical outcome.
-
extraction step
Day 4: harvesting (virus-containing)
-
washing step
DCs are washed.
-
manufacturing step
refolded CD1 molecules are used to generate CD1 tetramers
-
manufacturing step
The DC vaccine will consist of monocyte derived DC loaded with tumor lysate generated from the excised lesion.
-
material processing step
Such prepared DC will be used also to expand T cells (isolated during the elutriation) for subsequent adoptive transfer.
-
adding substance to cell culture step
The DC with blocking receptors are exposed to fungi.
-
material component separation step
Sources for tumor antigens as well as monocytes and T cells will be isolated from the leukapheresis product by elutriation.
-
electroporation step
Dendritic cells are electroporated.
-
electroporation step
Electroporation of autologous DCs electroporated with mRNA encoding CD40L, CD70, caTLR4 and one tumorantigen (gp100, Tyrosinase, Mage-C2 or Mage-A3) to produce the vaccine
-
extraction step
Elutriation of the leukapheresis product.
-
material combination step
Leukapheresis products from cancer patients is used as a starting material for monocyte enrichment by elutriation technology with ELUTRA® (Gambro).
-
material combination step
Blue formazan particles are dissolved using 2M KOH and DMSO.
-
adding substance to cell culture step
After peptide pulsation cells are diluted in medium containing 20 ng/mL TNF-?, plus IL-4 and GM-CSF as stated above.
