Dendritic Cell Vaccine
This intervention distinguishes itself from others by utilizing allogeneic dendritic cells derived from healthy donors fused with autologous tumor cells from patients, which is a novel approach compared to the commonly used autologous DC-based vaccines (DCVax).
Pembrolizumab
Recent findings have shown that the anti-PD1 monoclonal antibody, a checkpoint inhibitor, can sustainably enhance the anti-tumor immune response. In this study, all patients in the intervention group (vaccine) who reach the fifth dose will be randomized to receive either pembrolizumab or a placebo as an addition to the experimental treatment regimen.
Placebo
In this study, all patients in the intervention group (vaccine) who reach the fifth dose will be randomized to receive either pembrolizumab or a placebo as an addition to the experimental treatment regimen.
