Design outcomes

Primary

MeasureTime frame
Correlation between BIM-gamma mRNA levels in CTC and PFS with osimertinib at baseline

Secondary

MeasureTime frame
1) Detection rate of mRNA and DNA of prognostic factors (PD-L1, HER2, MET, VEGFRA, PUMA , EGFR T790M, C797S, BIM-gamma, EL, L, and S) in CTC and cfDNA 2) Number of CTC extracted 3) Correlation between the expression of BIM-gamma mRNA in CTC and ORR with osimertinib 4) Correlation between the expression of mRNA of prognostic factors (PD-L1, HER2, MET, VEGFRA, PUMA, EGFR, BIM-EL, L, and S) in CTC and PFS and ORR with osimertinib 5) Correlation between the expression of prognostic factors (PD-L1, HER2, MET, VEGFRA, PUMA , EGFR, BIM-gamma, EL, L, and S) in cfDNA and PFS and ORR with osimertinib 6) EGFR sensitive mutation and DNA expression of T790M in CTC and cfDNA 7) Detection rate of EGFR C797S mutation in CTC and cfDNA 8) Correlation between mRNA level of BIM-gamma in CTC and PFS of the patients with Osimertininb (during Osimertinib treatment)
