Supplementary Figure S3. Computed tomography of the chest showed response to
radiotherapy (left), but progression during AZD9291 at a dose of 40mg once daily
(middle) and after intra-patient dose escalation to 80mg once daily (right).

Supplementary Figure S4. Targeted exome sequencing results were visualized with
Integrated Genome Viewers for the EGFR exon 19 in-frame deletion and EGFRT790M
mutations in Patients 1 to 4 (A - D).

Supplementary Figure S5. EGFR, MET, and HER2 per centromere evaluation probe ratio were summarized (A).
Representative FISH results of EGFR and MET in Patient 1 showed high polysomy according to the Colorado scoring criteria
and no MET amplification (B). Although EGFR amplification was observed before and after AZD9291, MET amplification was not
observed in Patient 2 (C)

Supplementary Figure S6. Targeted exome sequencing showed PTEN deletion
with Integrated Genome Viewers in post-AZD9291 tumors of Patients 4.

Supplementary Figure S7. Copy number analysis and relative mRNA expression of EGFR and alternative pathway genes.
qPCR method was used to determine relative mRNA expression levels as well as copy number of genes, according to the
protocols provided by Applied Biosystems (Life Technologies).

Supplementary Figure S8. Cell proliferation assay of HCC4006 cells treated with 50 ng/ml FGF2 showed resistance to
AZD9291 (A). AZD9291-resistant HCC4006AR1 and HCC4006AR2 cells showed higher sensitivities to selective FGFR1
inhibitors, PD173074 (B) and BGJ398 (C).

Supplementary Figure S9. Immunoblotting of oncogenic downstream signals for
parental and AZD9291-resistant NSCLC cells after exposure to AZD9291. The
expression levels of signaling molecules were shown after a 4 hour incubation at 0,
0.1 and 1 μM concentrations of AZD9291 (A). AZD9291-resistant NSCLC cells were
resistant to AZD9291 plus selumetinib or BYL719 (B).

Supplementary Figure S10. Cell proliferation assays were performed in parental and AZD9291-resistant NSCLC cells treated
with AZD9291 for 72 hours (A and C). The copy number analysis and relative mRNA expression of EGFR and alternative
pathway genes in NSCLC cells were performed using a qPCR method (B and D). HCC4006AR1-2 cells with AXL up-regulation
were resistant to an AXL inhibitor (E).

Supplementary Figure S11. Images of the chest showed dramatic response to salvage radiotherapy (A), but refractory disease
after one cycle of etoposide and carboplatin (B). Malignant pleural effusions were obtained for establishing SNU-2962A cells that
expressed CD56, chromogranin A, and synaptophysin (C). SNU-2962A cells harbored no EGFRT790M mutation (D) and low RB1
mRNA expression (E). SNU-2962A cells were resistant to AZD9291 (IC50, 3774.6±462.7 nM), but sensitive to paclitaxel (IC50,
0.998±0.046 nM) (F).
