Sequential therapy of anti-PD-1 and anti-CTLA-4. (A) From top to bottom: Tumor response to sequential therapy with dosing as listed in phase II CheckMate 064 trial (NCT01783938) with regimens shown in bottom two figures. Following response (top), effector T cell density in the tumor (second from the top), mAPC density in the lymph nodes (third from the top) and finally, the PK of anti-PD-1 first regimen and lastly, anti-CTLA-4 first regimen. (B) Anti-PD-1 therapy first: Comparison of variability in responses (top), waterfall plots of responders in virtual trial (second from top), Bar graph comparison parameters varied in model for each responder type (third from top), and boxplots of Max effector T cell density in the tumor and average mAPC density in the lymph nodes (bottom) for each responder category: virtual non-responders (NR), stable disease (SD) and partial or complete responders (CR/PR). (C) Same as (B), except for anti-CTLA-4 therapy administered first.
