Cancer vaccines in the era of checkpoint blockade: the magic is in the adjuvant.

Cancer vaccines in the era of checkpoint blockade: the magic is in the adjuvant. Curr Opin Immunol. 2017 Aug 11;47:103-109 Authors: Overwijk WW Abstract While T cell checkpoint blockade therapy of various cancers yields impressive clinical benefits, most patients are not cured. This is thought to result from insufficient spontaneous tumor-specific T cell responses, a situation that could be remedied with cancer-specific vaccination. Much work is underway to identify cancer-specific antigens, leaving open the question of how to formulate these antigens in a manner that provokes potent cancer-specific T cell responses. In this review I discuss paradigms guiding adjuvant development, and consider what may constitutes a clinically relevant T cell response. I also suggest that adjuvants providing multiple non-redundant signals may be the next frontier in the development of cancer vaccines that provide true clinical benefit when combined with T cell checkpoint blockade.
