Supplementary Figure S1. Determination of the binding mode of the FGFR inhibitor CH /Debio Lineweaver-Burk plot of FGFR1 with different concentrations of ATP in presence of various concentrations of CH /Debio Linear graphs intersected all with y-axis (i.e. V max unchanged) which does support an ATP-competitive mode-of-action of CH /Debio 1347 for FGFR1. Supplementary Figure S1.

Supplementary Figure S3. Kinase activity of FGFR2 WT, V564F, V564I, and V564L mutants. The 293 cells were transiently transfected with pCXND3 FGFR2 WT, FGFR2 V564F, FGFR2 V564I, and FGFR2 V564L. The kinases were immunoprecipitated with anti-FGFR2 antibody. Then, kinase activity was evaluated by examining their ability to phosphorylate substrate peptide using a time-resolved fluorescence resonance energy transfer (TR-FRET) assay. (N=2) Relative kinase activity of FGFR2 to mock Supplementary Figure S3.
Supplementary Figure S4. Inhibition of cellular pY-FGFR2 WT, pY-FGFR2 V564F, pY- FGFR2 V564I, and pY-FGFR2 V564L. The HCT-116 cells were transiently transfected with pCXND3 FGFR2 WT, FGFR2 V564F, FGFR2 V564I, and FGFR2 V564L. A day after the transfection, the cells were treated with the indicated concentration of CH /Debio 1347 or AZD4547 for 2 h. Cells were extracted and analyzed by Western blotting.

(A) Anti-proliferative activity of PD and cediranib against TEL-FGFR2 WT driven Ba/F3 cells and TEL-FGFR2 V564F-driven Ba/F3 cells. Three clones were treated with various concentrations of the indicated inhibitors for 4 days. The viable cells were counted with WST-8.

(A) Mice bearing Ba/F3 TEL-FGFR2 WT cells were treated with CH /Debio 1347 or AZD4547 orally once daily for 11 days at the indicated doses. Tumor volume and body weight change for each dose group were measured. Data are shown as mean ± SD (n = 5). (B) Suppression of phospho-FGFR inhibition in xenograft tissue. Mice bearing Ba/F3 TEL- FGFR2 WT cells were treated for 11 days at 50 and 100 mg/kg of CH /Debio 1347 or 25 and 50 mg/kg of AZD4547, and xenograft tumors were extracted at 4 hours post- dosing and analyzed by Western blotting.
