7 First-line Immunotherapy Pembrolizumab is approved for patients with PD-L1 expression >50% as monotherapy Pembrolizumab plus chemo is approved for 1 st line treatment of nonsquamous NSCLC Patient selection methods for using combination versus monotherapy are needed Confirmatory studies of chemo plus PD-1/PD-L1 inhibition are awaited 7

8 Treatment Algorithm for Advanced NSCLC Stage IV NSCLC Molecular testing for EGFR, ALK, ROS1 IHC for PD-L1 Expression EGFR, ALK or ROS1 PD-L1 > 50% No targetable mutation PD-L1 < 50% No Targetable mutation Targeted therapy 1. Pembrolizumab 2. Pembro Plus Chemo (Non-sq) * Bevacizumab/necitumumab added when appropriate 1. Platinum-based chemotherapy* 2. Chemo plus Pembro (Non-sq) 8
