The DCs will be generated in vitro from peripheral blood mononuclear cells (PBMCs) which will be obtained from 30 ml of peripheral blood collected from each patient with metastatic cancer by venipuncture in heparin tubes. The cellular viability, the expression of maturation biomarkers and the presence of several cytokines will be evaluated by flow cytometric assays after the culture period of DCs exposed to the peptides. An interim analysis is programmed with the first 10 patients. If an effect is demonstrated the study will include an additional number of subjects sufficient to ensure adequate comparison with other commercially available peptides.
