Other related information

Approximately 20 mL of blood samples will be collected at the following three time points: before treatment with
osimertinib, at one month of treatment, and at the time of recurrence. The number of copies of T790M, C797S, and
sensitive mutations (Del19 or L858R) in these blood samples will be determined using a digital PCR system (Bio-Rad
Laboratories, Inc.) for a quantitative assessment. Changes in the quantified number of copies of T790M and C797S after
the start of treatment with osimertinib will be assessed in terms of response rate and survival time (progression-free
survival and overall survival) for an exploratory investigation of the potential of these mutations as treatment predictive
biomarkers.
Moreover, the effect of the number of copies of T790M before treatment on prognosis after treatment, i.e., the role of the
number of copies of T790M as a prognostic factor, will be assessed, and any relationship between percent reductions in
the number of copies themselves and the therapeutic effect of osimertinib will be clarified. As factors affecting this
therapeutic effect, the expression levels of PIK3CA, BRAF, EMT, MET, and HER2, possible causative factors for the
resistance to first- and second-generation EGFR TKIs, will be assessed through analysis of gene mutations and
amplifications in DNA samples extracted from re-biopsy tumor specimens before treatment, to determine a correlation
between the therapeutic effect of osimertinib and the number of copies of the T790M, C797S, and sensitive mutations,
and other relationships.
