We performed a meta-analysis to assess the role of immune checkpoint inhibitors as second-line therapy in EGFR-mutant advanced NSCLC.

Randomized trials comparing immune checkpoint inhibitors against chemotherapy were identified. We retrieved the hazard ratio (HR) and 95% confidence interval (CI) for overall survival (OS) of the intention-to-treat population and EGFR mutation–defined subgroups. We used the fixed-effects inverse variance–weighted method to pool estimates of treatment efficacy. Statistical tests were two sided.

In the three included studies that compared immune checkpoint inhibitors (nivolumab [n = 292], pembrolizumab [n = 691], and atezolizumab [n =144]) against docetaxel (n = 776), immune checkpoint inhibitors significantly prolonged OS over that with docetaxel overall (n = 1903, HR = 0.68, 95% CI: 0.61–0.77, p < 0.0001) and in the EGFR wild-type …
