Supplementary Figure S6 from Early Clearance of Plasma Epidermal Growth Factor Receptor Mutations as a Predictor of Outcome on Osimertinib in Advanced Non-Small Cell Lung Cancer; Exploratory Analysis from AURA3 and FLAURA

Kaplan–Meier estimates showing investigator-assessed PFS in FLAURA trial patients by clearance or non-clearance of plasma EGFRm status at Weeks 3 or 6 in patients who had baseline detectable plasma EGFRm. For comparison, patients with baseline non-detectable plasma EGFRm are included. A, Osimertinib arm by Week 3 plasma EGFRm status (n = 238). B, Comparator EGFR-TKI arm by Week 3 plasma EGFRm status (n = 243). C, Osimertinib arm by Week 6 plasma EGFRm status (n = 240). D, Comparator EGFR-TKI arm by Week 6 plasma EGFRm status (n = 235). Censored data are indicated by tick marks. Abbreviations: CI, confidence interval; EGFRm, epidermal growth factor receptor mutation (ex19del or L858R); NC, not calculable; mPFS, median PFS; TKI, tyrosine kinase inhibitor.
