Study Arms:
- Myeloid dendritic cells (mDC) vaccinations (Type: EXPERIMENTAL): Patients will be vaccinated intranodally three times biweekly with mDC (5x 106 cells; n=7, arm A). DC will be loaded with major histocompatibility complex (MHC) class I binding peptides of tumor antigens and NY-ESO-1 and MUC1 PepTivator® which covers the complete antigen. DC will be stimulated with protamine/mRNA and loaded with keyhole limpet hemocyanin (KLH) as an immune control.
- Plasmacytoid dendritic cells (pDC) vaccinations (Type: EXPERIMENTAL): Patients will be vaccinated intranodally three times biweekly with pDC (3x 106 cells; n=7, arm B). DC will be loaded with MHC class I binding peptides of tumor antigens and NY-ESO-1 and MUC1 PepTivator® which covers the complete antigen. DC will be stimulated with protamine/mRNA.
- mDC and pDC vaccinations (Type: EXPERIMENTAL): Patients will be vaccinated intranodally three times biweekly with the combination of mDC and pDC (5x 106 mDC/ 3x 106 pDC; n=7, arm C). DC will be loaded with MHC class I binding peptides of tumor antigens and NY-ESO-1 and MUC1 PepTivator® which covers the complete antigen. DC will be stimulated with protamine/mRNA and loaded with KLH (mDC only) as an immune control.
