Dendritic Cell Vaccination for Patients With Solid Tumors

The aim of this study is to evaluate the immunogenicity and clinical efficacy of intradermal vaccination with autologous RNA-modified dendritic cells (DCs) - engineered to express the WT1 protein - in patients with limited spread metastatic solid tumors, i.e. breast cancers, glioblastoma grade IV, sarcomas, malignant mesothelioma and colorectal tumors. Based on the results of our previously performed phase I study with autologous WT1 mRNA-transfected DC, the investigators hypothesize that the vaccination with DC will be well-tolerated and will result in an increase in WT1-specific CD8+ T cell responses.
