Core Tip

Core tip: Dendritic cell (DC)-based cancer vaccine is expected as a strategy to augment the antigen-specific anti-cancer immune response. Vaccell, a DC vaccine which was optimized to fight against a cancer, has been developed in Japan. Here, we reviewed the development and clinical effects of the “Vaccell”. We conducted large-scale retrospective observations as well as prospective clinical trials, and obtained the findings strongly suggesting that there are “Responders” that the clinical benefits are provided by the DC vaccine. We are now planning a pivotal study of the Vaccell in Japan.
