ABSTRACT: Purpose
Although the efficacy of programmed cell death-1 (PD-1) blockade is generally poor for non-small cell lung cancer (NSCLC) with activating mutations of the epidermal growth factor receptor (EGFR) gene, EGFR tyrosine kinase inhibitors (TKIs) may improve the tumor immune microenvironment. We performed a randomized study to assess whether nivolumab improves outcome compared with chemotherapy in such patients previously treated with EGFR-TKIs.Patients and methods
Patients with EGFR-mutated NSCLC who acquired EGFR-TKI resistance not due to a secondary T790M mutation of EGFR were randomized 1:1 to nivolumab (n = 52) or carboplatin-pemetrexed (n = 50). The primary endpoint was progression-free survival (PFS).Results
Median PFS and 1-year PFS probability were 1.7 mon
