- Description
- In an in vitro study, a Ba/F3 cell line expressing EGFR D770_N771insSVD demonstrated reduced sensitivity to erlotinib treatment (IC50=3.187�M), comparable to Ba/F3 cells expressing EGFR L858R and T790M co-mutation (T790M is a known resistant mutation to 1st and 2nd generation EGFR tyrosine kinase inhibitors; IC50=4.155�M). Resistance was determined by assessing cell proliferation, EGFR, AKT and ERK phosphorylation.
