In patients with advanced NSCLC without EGFR, ALK, or ROS1 genomic tumor aberrations, treatment with cemiplimab plus chemotherapy showed a consistent relationship between ORR and baseline PD-L1 expression, with benefits versus chemotherapy alone seen across all levels of baseline PD-L1 expression; there was also a clear association between a continuous measure of changes in tumor size over time and baseline PD-L1 expression. Cemiplimab is only the second anti-PD-1/PD-L1 agent to show efficacy in advanced NSCLC as both monotherapy and in combination with chemotherapy for both squamous and non-squamous histologies.
