PF299804 is a potent, orally available, irreversible tyrosine kinase HER 1 (EGFR), HER2 and HER4 inhibitor with IC50 of 6, 45.7 and 73.7 nM for EGFR, ERBB2 and ERBB4, respectively.PF299804 is a quinazalone-based irreversible pan-ERBB inhibitor structurally related to CI-1033. PF299804 is a potent inhibitor of EGFR-activating mutations as well as the EGFR T790M resistance mutation both in vitro and in vivo. Additionally, PF299804 is a highly effective inhibitor of both the wild-type ERBB2 and the gefitinib-resistant oncogenic ERBB2 mutation identified in lung cancers. PF299804 effectively inhibited the in vitro kinase activity of wild-type EGFR with similar efficacy as gefitinib, erlotinib, andCI-1033. In contrast to gefitinib and erlotinib, PF299804 also effectively inhibited wild-type ERBB2. LCK and SRC were the only other kinases inhibited by PF299804 although with >10 fold higher IC50 than against EGFR. PF299804 inhibited cellular EGFR and ERBB 2 with IC50 of 5.8 and 41 nM in NIH3T3/EGFR cell and NIH3T3/ERBB2 cell, respectively. PF299804 is active in E-sensitive and -resistant preclinical models. PF299804 had clinical activity in phase I/II trials in EGFR TK inhibitor (TKI)-refractory NSCLC. PF299804 is originally developed by Seoul National University Hospital and Pfizer. The phase II clinical trials for PF299804 was performing in the treatment of advanced gastric cancer.
