47 T-Cell Checkpoint Inhibitors in Patients with EGFR-mutant Lung Cancers Patients with EGFR-mutant lung caners excluded from pivotal clinical trials scant data Tumors with EGFR mutations generally have a low mutational burden. PR in 4%, PD-L1 >50% in 11%, high level TILs in 2% (Gainor Clin Cancer Res 2016) No consensus on what to do if a patient tumor has both EGFR mutation and PD-L1 > 50%. Some data Recommend frank discussion with the patient.favor PD-L1 drug 1 st.

51 YES1 amplification: a new mechanism of acquired resistance to all EGFR kinase inhibitors in EGFR-mutant lung cancers YES1 is a Src family kinase (SFK) that phosphorylates YES1-associated protein 1 (YAP1), a Hippo pathway effector implicated in resistance to multiple targeted therapies Overexpression of YES1 a resistance mechanism in the EGFR-mutant PC9 lung adenocarcinoma cells by two different approaches: 1) generation of osimertinib-resistant cells through gradual dose escalation and 2) a forward transposon mutagenesis screen to recover afatinib-resistant PC9 derivatives Cells overexpressing YES1 exhibited resistance to all 3 generations of EGFR TKIs but sensitivity to SFK inhibitors Analysis of MSK-IMPACT data for 136 cases of acquired resistance to EGFR TKIs revealed 4 cases with YES1 amplification, 3 of which lacked other mechanisms of resistance Ichihara, Cancer Research 2017, Fan (MSK) submitted for publication

56 Molecular Therapeutics in Lung Cancers Conclusions The discovery of oncogenic drivers and the identification of drugs to target them has transformed the care of persons with lung cancers Multiplex NGS testing at diagnosis permits the selection of the best initial targeted and immunotherapies New trial designs can accelerate progress across diseases Disease agnostic therapies have arrived more are on the way New therapies and paradigms have radically changed research priorities. Time to reboot. As we search for cures, we must meet the challenge to bring the best drug at the best time to each patient with lung cancer today
