Advanced NSCLC Monotherapy Treatment

Subgroup Analysis:
Baseline characteristics

Approved in patients with advanced NSCLC* with PD-L1 ≥50% and no EGFR, ALK, or ROS1 aberrations1

Analysis of overall survival by subgroups2

Limitations:

OS subgroup analyses were not powered to show a statistically significant difference among or within individual subgroups. Furthermore, histology, brain metastases at baseline, and cancer stage at screening were not prespecified subgroup analyses. Firm conclusions cannot be made based on these subgroup analyses.

Post hoc analysis of overall survival by subgroups1

Limitations:

OS subgroup analyses were not powered to show a statistically significant difference between or within individual subgroups. Furthermore, none of the subgroup analyses were prespecified in the subset of patients with known PD-L1 ≥50%. Firm conclusions cannot be made based on these subgroup analyses.
