Supplementary Figure S6 from Early Clearance of Plasma <i>Epidermal Growth Factor Receptor</i> 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.</p

FLAURA flow diagram for ctDNA analysis (n = 499). Clearance refers to non-detectable plasma EGFRm, where EGFRm was detectable at baseline. *There were 3 patients in the osimertinib arm and 7 patients in the comparator EGFR-TKI arm without a valid ddPCR result at Weeks 3 and 6; these samples were excluded from the ctDNA clearance analysis. Abbreviations: ctDNA, circulating tumor DNA; EGFRm, epidermal growth factor receptor mutation (ex19del or L858R); TKI, tyrosine kinase inhibitor.</p

AURA3 flow diagram for ctDNA analysis (n = 291). Clearance refers to non-detectable plasma EGFRm, where EGFRm was detectable at baseline. *There were 9 patients in the osimertinib arm and 1 patient in the platinum-pemetrexed arm without a valid ddPCR result at Weeks 3 and 6; these samples were excluded from the ctDNA clearance analysis. Abbreviations: ctDNA, circulating tumor DNA; EGFRm, epidermal growth factor receptor mutation (ex19del or L858R).</p

Correlation between EGFRm allelic fraction at baseline by ddPCR (Biodesix) and NGS (Guardant Health) analyses in A, patients from the AURA3 trial (n = 202) and B, patients from the FLAURA trial (n = 347). Abbreviations: ddPCR, droplet digital PCR; EGFRm, epidermal growth factor receptor mutation (ex19del or L858R); NGS, next-generation sequencing.</p

Assessment of correlation between EGFRm VAF in baseline plasma and investigator-assessed PFS in A, patients from the AURA3 trial, by treatment arm and B, patients from the FLAURA trial, by treatment arm. Abbreviations: CR, complete response; EGFRm, epidermal growth factor receptor mutation (ex19del or L858R); NE, not evaluable; PD, progressive disease; PFS, progression-free survival; PR, partial response; SD, stable disease; VAF, variant allelic fraction.</p

Kaplan–Meier estimates showing OS in all trial patients with a valid baseline (detectable or non-detectable) plasma ctDNA result in A, patients from the AURA3 trial (n = 291) and B, patients from the FLAURA trial (n = 499). Censored data are indicated by tick marks. Abbreviations: CI, confidence interval; EGFRm, epidermal growth factor receptor mutation (ex19del or L858R); HR, hazard ratio; mOS, median overall survival; NC, not calculable.</p
