First-in-human Interleukin-15-transpresenting Wilms' Tumor Protein 1-targeting Autologous Dendritic Cell Vaccination in Cancer Patients

The investigational medicinal product concerns dendritic cells that were engineered to target the tumor antigen Wilms' Tumor-1 (WT1) and in addition transpresent the cytokine IL15 on their cell surface. By inclusion of the IL15-transpresentation mechanism, the intention is to render the dendritic cell more immunogenic (i.e. they have a higher capacity to stimulate the immune system to recognize and attack WT1-expressing cancer cells).
