Clinical Trial Summary

To assess the efficacy of single-agent osimertinib in relation to EGFR T790M mutant allele fraction (AF) in a real-world setting.

Description:

This study will assess the efficacy and safety of single-agent osimertinib in patients with locally advanced or metastatic EGFR T790M-positive NSCLC within the context of the early access program in Hong Kong. In particular, osimertinib treatment efficacy will be assessed in the context of the relationship between EGFR T790M mutant AF and survival outcomes, particularly overall survival. In a real-world setting, analysis of overall survival benefit is considered less sensitive to differences in healthcare systems and standards. Other clinical outcomes including response rate (based on physician's judgement) and time to treatment discontinuation (TTD) will be examined. This study will also describe current practice for molecular testing and EGFR mutation profiles in this patient population.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Association between T790M mutant status and overal survival	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	Followed up to 2 years after last patient in
Secondary	Overal survival (OS)	To estimate OS of subjects with advanced/metastatic EGFR T790M-positive NSCLC treated with osimertinib	Followed up to 2 years after last patient in
Secondary	RR	To estimate response rate (RR) and disease control rate (DCR) based on physician's judgement, for the overall study population.	Follow up within 6 months after last patient in
Secondary	TTD	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)	Followed up to 12 months after last patient in
Secondary	Adverse event of special interest	To assess by number of adverse events of special interest which are pre-defined in protocol, as recorded on the case report form.	Followed up to 12 months after last patient in
Secondary	T790M mutation testing sample	To describe what sample or biopsy collected for testing after disease progression on, or discontinuation of, EGFR TKI therapy in the study population	Within 14 days after enrollment date
Secondary	T790M mutation testing platform	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	Within 14 days after enrollment date
Secondary	EGFR testing mutation subtype	To describe the EGFR mutation status of study subjects after disease progression on, or discontinuation of, EGFR TKI therapy	Within 14 days after enrollment date
Secondary	Treatment pattern	To describe treatment regimens received by study subjects before and after the start of osimertinib therapy.	Followed up to 2 years after last patient in
