Negative immune regulatory pathways inhibit anti-cancer T cell responses, preventing effective immune surveillance. Two clinical trials using monoclonal antibodies that antagonize the PD-1/PD-L1 pathway recently reported regression in several tumor types. In one of these trials, efficacy was linked to the expression of the PD-L1 biomarker on tumor cells.
