Description
In an in vitro study using NCI-H1666 cells (wildtype EGFR) and NCI-H1975 cells (EGFR-L858R/T790M), inhibition of cell growth was used as an assay to determine sensitivity to tyrosine kinase inhibitor (TKI) drugs. Cells with an EGFR L858R/T790M mutation demonstrated an improved response to canertinib (IC50: 101nM vs. >4000nM) compared to the same cells treated with erlotinib. IC50 values of canertinib were comparable to afatinib.
