In the FLAURA phase 3 study, the third-generation EGFR-TKI osimertinib significantly improved progression-free survival (PFS) vs SoC EGFR-TKIs (gefitinib or erlotinib) in pts with previously untreated Ex19del/L858R (EGFRm) advanced NSCLC (hazard ratio [HR] 0.46 [95% CI 0.37, 0.57]; p < 0.001). Interim overall survival (OS) data was encouraging but not formally statistically significant (HR 0.63 [95% CI 0.45, 0.88]; p = 0.007). Here we report exploratory post-progression outcomes.
