Drug: Osimertinib
80mg oral daily |
- Association between T790M mutant status and overal survival [ Time Frame: Followed up to 2 years after last patient in ]To assess the association of EGFR T790M mutant allele fraction (AF) level with the overall survival (OS) of subjects with advanced/metastatic EGFR T790M-positive NSCLC treated with osimertinib
- Overal survival (OS) [ Time Frame: Followed up to 2 years after last patient in ]To estimate OS of subjects with advanced/metastatic EGFR T790M-positive NSCLC treated with osimertinib
- RR [ Time Frame: Follow up within 6 months after last patient in ]To estimate response rate (RR) and disease control rate (DCR) based on physician's judgement, for the overall study population.
- TTD [ Time Frame: Followed up to 12 months after last patient in ]To estimate time to treatment discontinuation (TTD) of osimertinib for the overall study population, and for subjects with different EGFR mutation status (T790M/Exon 19 del; T790M/L858R)
- Adverse event of special interest [ Time Frame: Followed up to 12 months after last patient in ]To assess by number of adverse events of special interest which are pre-defined in protocol, as recorded on the case report form.
- T790M mutation testing sample [ Time Frame: Within 14 days after enrollment date ]To describe what sample or biopsy collected for testing after disease progression on, or discontinuation of, EGFR TKI therapy in the study population
- T790M mutation testing platform [ Time Frame: Within 14 days after enrollment date ]To describe the characteristics of the methods used for T790M mutation testing after disease progression on, or discontinuation of, EGFR TKI therapy in the study population
- EGFR testing mutation subtype [ Time Frame: Within 14 days after enrollment date ]To describe the EGFR mutation status of study subjects after disease progression on, or discontinuation of, EGFR TKI therapy
- Treatment pattern [ Time Frame: Followed up to 2 years after last patient in ]To describe treatment regimens received by study subjects before and after the start of osimertinib therapy.
