Intratumoral Injection of Autologous CD1c (BDCA-1)+ MyDC, Avelumab, and Ipilimumab Plus Systemic Nivolumab

Summary

This phase II trial aims at investigating the role and effect of autologous CD1c (BDCA-1)+ myeloid dendritic cells in combination with intratumoral injection of the CTLA-4 blocking monoclonal antibody (mAb) ipilimumab and the immunoligand AS01B compared to a combinatorial immunotherapy regimen using intratumoral injection of the CTLA-4 blocking monoclonal antibody (mAb) ipilimumab and the immunoligand AS01B. Concomitantly, nivolumab (a PD-1 blocking mAb) will be administered intravenously in both arms.
