NCIt definition : An orally bioavailable dual inhibitor of epidermal growth factor receptor (EGFR) and
human epidermal growth factor receptor 2 (ErbB-2 or HER-2), and an analog of the quinazoline
lapatinib, with potential antineoplastic activity. Upon administration, selatinib
reversibly blocks phosphorylation of both EGFR and ErbB2, thereby suppressing tumor
growth in EGFR/ErbB-2-overexpressing tumor cells. The tyrosine kinases EGFR and ErbB2
have been implicated in the growth of various tumor types.;
