AstraZeneca350 enrolled

Overview

This is a retrospective, observational study of treatment patterns and clinical outcomes in Australian EGFRm advanced and metastatic non-small cell lung cancer patients treated with first-line osimertinib or second-line osimertinib.

This study utilizes secondary data collected as part of the AUstralasian thoRacic cancers lOngitudinal cohoRt study and biobAnk (AURORA), which is registered on the Australian New Zealand Clinical Trial Registry: ACTRN12625000038493. Objectives: In stage IIIB-IV patients with EGFRm NSCLC treated with Osimertinib in the 1L or T790M+ 2L setting in Australia: Primary Objectives: To describe the Osimertinib Time to Treatment Discontinuation (TTD) in the 1L and 2L settings (as separate cohorts). Secondary Objectives: To describe the real-world progression-free survival (rwPFS), overall survival (OS), time to next treatment (TTNT) after Osimertinib, patient demographics and clinical characteristics, patterns of care (e.g additional therapies received during and after Osimertinib) in 1L and 2L (T790M+) patients (as separate cohorts).
