Genetic Predictors of Benefit to Pembrolizumab

The primary objective is to determine if mutation load underlies sensitivity to pembrolizumab alone and in combination with chemotherapy. This will be a 3-arm, multi-center, open-label, non-randomized biomarker trial in patients with advanced, treatment-naive NSCLC. Patients will receive 1 of 3 possible cohorts as per investigator's discretion. Patients with non-squamous histology may receive any of the 3 cohorts; patients with squamous histology may receive either cohorts 1 and 2.
