Purpose: To assess the utility of the cobas EGFR Mutation Test, with tissue and plasma, for first-line osimertinib therapy for patients with EGFR -mutated ( EGFR m; Ex19del and/or L858R) advanced or metastatic non-small cell lung cancer (NSCLC) from the FLAURA study (NCT02296125)., Experimental Design: Tumor tissue EGFR m status was determined at screening using the central cobas tissue test or a local tissue test. Baseline circulating tumor (ct)DNA EGFR m status was retrospectively determined with the central cobas plasma test., Results: Of 994 patients screened, 556 were randomized (289 and 267 with central and local EGFR test results, respectively) and 438 failed screening. Of those randomized from local EGFR test results, 217 patients had available central test results; 211/217 (97%) were retrospectively confirmed EGFR m positive by central cobas tissue test. Using reference central cobas tissue test results, positive percent agreements with cobas plasma test results for Ex19del and L858R detection were 79% [95% confidence interval (CI), 74-84] and 68% (95% CI, 61-75), respectively. Progression-free survival (PFS) superiority with osimertinib over comparator EGFR-TKI remained consistent irrespective of randomization route (central/local EGFR m-positive tissue test). In both treatment arms, PFS was prolonged in plasma ctDNA EGFR m-negative (23.5 and 15.0 months) versus -positive patients (15.2 and 9.7 months)., Conclusions: Our results support utility of cobas tissue and plasma testing to aid selection of patients with EGFR m advanced NSCLC for first-line osimertinib treatment. Lack of EGFR m detection in plasma was associated with prolonged PFS versus patients plasma EGFR m positive, potentially due to patients having lower tumor burden., (©2019 American Association for Cancer Research.)

Purpose: In the phase III FLAURA study, third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) osimertinib significantly improved progression-free survival (PFS) versus standard-of-care (SoC) EGFR-TKI (gefitinib or erlotinib) in patients with previously untreated EGFR (exon 19 deletion or L858R) mutation-positive advanced non-small cell lung cancer (NSCLC). Interim overall survival (OS) data were encouraging, but not formally statistically significant at current maturity (25%). Here we report exploratory postprogression outcomes., Patients and Methods: Patients were randomized 1:1 to receive osimertinib (80 mg orally, once daily) or SoC EGFR-TKI (gefitinib 250 mg or erlotinib 150 mg, orally, once daily). Treatment beyond disease progression was allowed if the investigator judged ongoing clinical benefit. Patients receiving SoC EGFR-TKI could cross over to receive osimertinib after independently confirmed objective disease progression with documented postprogression T790M-positive mutation status., Results: At data cutoff (June 12, 2017), 138 of 279 (49%) and 213 of 277 (77%) patients discontinued osimertinib and SoC EGFR-TKI, respectively, of whom 82 (59%) and 129 (61%), respectively, started a subsequent treatment. Median time to discontinuation of any EGFR-TKI or death was 23.0 months [95% confidence interval (CI), 19.5-not calculable (NC)] in the osimertinib arm and 16.0 months (95% CI, 14.8-18.6) in the SoC EGFR-TKI arm. Median second PFS was not reached (95% CI, 23.7-NC) in the osimertinib arm and 20.0 months (95% CI, 18.2-NC) in the SoC EGFR-TKI arm [hazard ratio (HR), 0.58; 95% CI, 0.44-0.78; P = 0.0004]., Conclusions: All postprogression endpoints showed consistent improvement with osimertinib versus SoC EGFR-TKI, providing further confidence in the interim OS data., (©2019 American Association for Cancer Research.)

Background: Osimertinib is an oral, third-generation, irreversible epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) that selectively inhibits both EGFR-TKI-sensitizing and EGFR T790M resistance mutations. We compared osimertinib with standard EGFR-TKIs in patients with previously untreated, EGFR mutation-positive advanced non-small-cell lung cancer (NSCLC)., Methods: In this double-blind, phase 3 trial, we randomly assigned 556 patients with previously untreated, EGFR mutation-positive (exon 19 deletion or L858R) advanced NSCLC in a 1:1 ratio to receive either osimertinib (at a dose of 80 mg once daily) or a standard EGFR-TKI (gefitinib at a dose of 250 mg once daily or erlotinib at a dose of 150 mg once daily). The primary end point was investigator-assessed progression-free survival., Results: The median progression-free survival was significantly longer with osimertinib than with standard EGFR-TKIs (18.9 months vs. 10.2 months; hazard ratio for disease progression or death, 0.46; 95% confidence interval [CI], 0.37 to 0.57; P<0.001). The objective response rate was similar in the two groups: 80% with osimertinib and 76% with standard EGFR-TKIs (odds ratio, 1.27; 95% CI, 0.85 to 1.90; P=0.24). The median duration of response was 17.2 months (95% CI, 13.8 to 22.0) with osimertinib versus 8.5 months (95% CI, 7.3 to 9.8) with standard EGFR-TKIs. Data on overall survival were immature at the interim analysis (25% maturity). The survival rate at 18 months was 83% (95% CI, 78 to 87) with osimertinib and 71% (95% CI, 65 to 76) with standard EGFR-TKIs (hazard ratio for death, 0.63; 95% CI, 0.45 to 0.88; P=0.007 [nonsignificant in the interim analysis]). Adverse events of grade 3 or higher were less frequent with osimertinib than with standard EGFR-TKIs (34% vs. 45%)., Conclusions: Osimertinib showed efficacy superior to that of standard EGFR-TKIs in the first-line treatment of EGFR mutation-positive advanced NSCLC, with a similar safety profile and lower rates of serious adverse events.

Objective: The Phase III, randomized, open-label IPASS study (NCT00322452) of first-line epidermal growth factor receptor tyrosine kinase inhibitor (EGFR TKI) gefitinib versus carboplatin/paclitaxel for Asian patients with advanced non-small-cell lung cancer (NSCLC) showed that investigator-assessed progression-free survival (PFS) and objective response rate (ORR) were significantly prolonged in patients with EGFR mutation-positive NSCLC who received gefitinib versus patients with EGFR mutation-negative NSCLC. We report post-hoc analyses of IPASS data by blind independent central review (BICR), performed at the request of the US FDA, in a subset of patients with EGFR mutation-positive NSCLC., Patients and Methods: Eligible patients (aged ≥18 years; histologically/cytologically confirmed Stage IIB/IV adenocarcinoma NSCLC; non- or former light-smokers; treatment-naïve) were randomly assigned 1:1 to gefitinib (250mg/day) or carboplatin (dose calculated to produce an area under the curve of 5 or 6 mg/mL/minute)/paclitaxel (200mg/m 2 ). Primary endpoint: PFS. BICR analyses included PFS, ORR, and duration of response (DoR)., Results: Scans from 186 IPASS patients (gefitinib n=88, carboplatin/paclitaxel n=98) with EGFR mutation-positive NSCLC were available for BICR. Consistent with investigator-assessed results, in patients with EGFR mutation-positive NSCLC: PFS (hazard ratio 0.54; 95% confidence interval [CI] 0.38, 0.79; p=0.0012) and ORR (odds ratio 3.00; 95% CI 1.63, 5.54; p=0.0004) were significantly longer with gefitinib versus carboplatin/paclitaxel. The median DoR by BICR was 9.6 months with gefitinib and 5.5 months with carboplatin/paclitaxel., Conclusion: BICR analysis of IPASS data support the original, investigator-assessed results. EGFR mutation-positive status remains a significant predictor of response to first-line TKI therapy., (Copyright © 2016 The Authors. Published by Elsevier B.V. All rights reserved.)

Background Osimertinib is a 3rd-generation, irreversible, oral EGFR-TKI that potently and selectively inhibits both EGFR-mutated (EGFRm) and EGFR T790M resistance mutations, and has demonstrated efficacy in NSCLC CNS metastases. In the Phase III FLAURA study (NCT02296125), osimertinib resulted in significant progression-free survival (PFS) benefit (primary endpoint; datacut off [DCO] 12 June 2017) over comparator EGFR-TKI (HR 0.46, p < 0.001). Overall survival (OS) data were immature (25% maturity) at that time. Here, we report the final OS analysis (58% maturity). Methods Eligible patients (pts): ≥18 years (Japan: ≥20), treatment-naïve with Ex19del/L858R EGFRm advanced NSCLC; WHO performance status 0–1. Pts with stable CNS metastases not requiring steroids for ≥2 weeks were allowed. Pts were randomised 1:1 to osimertinib 80 mg once daily (qd) orally (po) or comparator EGFR-TKI (gefitinib 250 mg qd/erlotinib 150 mg qd po), stratified by mutation status (Ex19del/L858R) and race (Asian/non-Asian). Crossover was allowed for pts in the comparator EGFR-TKI arm upon central confirmation of progression and T790M positivity. Primary endpoint: PFS by RECIST v1.1, per investigator. OS was a secondary endpoint. DCO 25 June 2019. Results Globally, 556 pts were randomised to osimertinib (n = 279) or comparator EGFR-TKI (n = 277). Per study protocol, 70 (25%) pts crossed over from comparator EGFR-TKI to osimertinib. Osimertinib significantly improved OS vs comparator EGFR-TKI. All causality AEs, per investigator: osimertinib, 98% (grade ≥3, 42%); comparator EGFR-TKI, 98% (grade ≥3, 47%). AEs leading to discontinuation: osimertinib, 15%; comparator EGFR-TKI, 18%. The safety profile appears consistent with previously reported data.

Background In the phase III FLAURA study (NCT02296125), the 3rd-generation EGFR-TKI osimertinib showed superior efficacy to comparator EGFR-TKIs in previously untreated EGFR-mutated (EGFRm) advanced non-small cell lung cancer (NSCLC). Here we report results from an exploratory analysis of ctDNA for the early detection of disease progression (PD) in FLAURA. Methods Treatment-naïve patients (pts) with EGFRm (ex19del/L858R) locally advanced/metastatic NSCLC (n = 556) were randomised 1:1 (osimertinib 80 mg qd: comparator [gefitinib 250 mg qd/erlotinib 150 mg qd]). Plasma samples were collected on Days 1, 8 and 15, then every 21 days for weeks (W) 3–18, then every 6W thereafter. In pts who had a plasma sample on PD and/or discontinuation, ctDNA droplet digital PCR (ddPCR; Biodesix) for EGFRm (ex19del/L858R/T790M) was performed at all available time points and C797S for post-W6 time points. C797S and T790M were the only resistance mutations assayed. ctDNA progression was defined with respect to the nadir ctDNA result and its proximity to the ddPCR detection and quantification limits. Results The ctDNA progression analysis included 122/556 (22%) pts with valid longitudinal monitoring ddPCR data and RECIST PD by DCO1 (12 June 2017). Across both arms, ctDNA progression preceded or co-occurred with PD in 80/122 (66%) pts with 2.7 months (mo) median lead time; 9.5 mo median progression-free survival (mPFS; n = 80). Acquired C797S or T790M was detected in 57/122 (47%) pts with ctDNA progression (osimertinib 4/50 [8%] C797S, comparator 53/72 [74%] T790M); median time to detection was 16.7 and 8.4 mo for the osimertinib and comparator arms, respectively, mirroring overall mPFS. In pts with ctDNA progression and PD (n = 106), acquired T790M and C797S were detected either at the same time as, or earlier than PD in 41/106 (38%) pts (osimertinib 2/39 [5%], comparator 39/67 [58%]); median lead time was 1.4 mo. Conclusions ctDNA monitoring may allow for earlier identification of pts who progress on first-line EGFR-TKI therapy and the detection of EGFR-mediated resistance mechanisms in advance of PD in EGFRm NSCLC. Future work aims to explore early detection of non-EGFR-mediated resistance. Clinical trial identification NCT02296125.
