Is the game over for PD-1 inhibitors in EGFR mutant non-small cell lung cancer?

Maria A. Velez, Timothy F. Burns

Abstract

The immune checkpoint inhibitor pembrolizumab, has been shown to be efficacious and to have significant and durable antitumor activity in a subset of patients with advanced non-small cell lung cancer (NSCLC). Most notably in NSCLC with high expression of the programmed death ligand-1 (PD-L1). Similarly, there is abundant data to support the use of epithelial growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) as first-line therapy in patients whose tumors harbor EGFR mutations (1).
