ASK120067 is a potent and orally active inhibitor of EGFR^T790M (IC₅₀:0.3 nM) with selectivity over EGFR^WT (IC₅₀:6.0 nM). ASK120067 is a third-generation EGFR-TKI for the research of non-small cell lung cancer (NSCLC)^[1].

In the in vitro kinase assay ASK120067 potently inhibits the EGFR L858R/T790M and EGFR T790M resistant mutants with IC₅₀ values of 0.3 nM and 0.5 nM, respectively, as well as the EGFR^exon19del sensitizing mutant (IC₅₀= 0.5 nM). The ₅₀ of ASK120067 against wild-type EGFR (EGFR^WT) is 6 nM^[1].
ASK120067 selectively inhibits the growth of EGFR-mutant cell lines and exhibits potent antiproliferative activity in the mutant EGFR NSCLC cells, with IC₅₀ values of 12 nM, 6 nM and 2 nM against NCI-H1975 (T790M mutation), PC-9, and HCC827 cells (sensitizing mutations), respectively. However, it shows moderate or weak anti-growth activities in A431, LoVo and A549 cells (EGFR^WT), with IC₅₀ values ranging from 338 nM to 1541 nM^[1].
ASK120067 (0.1-100 nM) inhibits the phosphorylation of EGFR at Tyrosine residue 1068 and its downstream signaling proteins AKT and ERK in NCI-H1975 cells (EGFR^L858R/T790M) even at low dosage (0.1-1 nM). Additionally, ASK120067 inhibits p-EGFR and p-Akt and p-erk in EGFR WT A431 cell until the concentration reaches 10 to 100 nM^[1].

ASK120067 (oral gavage; 5-20 mg/kg; once daily; 21 days) results in significantly regressed tumor growth, with a tumor growth inhibition (TGI) rate of 85.7%, and administration of 10 mg/kg ASK120067 causes dramatic tumor shrinkage with a TGI rate of 99.3%, exhibiting a similar potency with Osimertinib^[1].
