Abstract 3564


Osimertinib, an oral, irreversible EGFR-TKI selective for sensitising (EGFRm) and T790M resistance mutations, has been shown to be effective and well tolerated in clinical studies for pts with EGFR T790M positive aNSCLC. Pts in France had early access to osimertinib through an ATU program before approval.


Pts with EGFR T790M positive aNSCLC were eligible if they had received prior EGFR-TKI therapy and a platinum-based chemotherapy (CT) or had CT intolerance; additional lines of therapy were permitted. T790M testing was performed by INCA (French National Cancer Institute) certified platforms.


From 07/04/2015 to 24/03/2016, 134 centres enrolled 364 pts; 99% had stage IV adenocarcinoma and 38.5% had brain metastases. Median therapies prior to osimertinib was 2 (1–9). The most frequent prior therapies were 1st line EGFR-TKI (66.2%; median duration 15.2 mo) and 2nd line platinum-based CT (42.0%).

As of March 2016, 350 pts were treated, 14 excluded (prescriber decision / pt death). 61% were treated ≥3 mo, 30% ≥6 mo and 14% ≥9 mo. Overall response rate (ORR) in 123 pts evaluable was 61.8% (95% CI 53, 70) (CR 5.7%, PR 56.1%). Disease control rate (CR + PR + SD) was 80.5% (99/123). 309/350 pts (88.3%) ongoing at data cutoff, 23 pts withdrawn for disease progression. Investigator reported safety data (n = 350) showed 36 pts (10.3%) experienced ≥1 treatment-related AE, 13 pts (3.7%) had AEs leading to discontinuation. 12 pts (3.4%) died (1 death drug related, attributed by investigator). 9 pts (2.6%) had AEs resulting in dose reductions; 3 pts (0.9%) had temporary interruptions.


In pts with EGFR T790M positive aNSCLC, osimertinib had antitumour activity with a similar ORR to that in clinical studies, with good tolerability. Identification of eligible pts is feasible in daily practice at tumour progression by T790M testing on rebiopsy or using ctDNA.
