Description
In an in vitro study, a Ba/F3 cell line expressing EGFR R776C demonstrated increased sensitivity to erlotinib treatment comparable to Ba/F3 cells expressing a known sensitizing mutation (EGFR L858R). Sensitivity was determined by assessing cell proliferation, the IC50 of erlotinib for EGFR V742A and EGFR L858R expressing cells were 47 nmol/L and 6 nmol/L, respectively.
