Masitinib (AB-1010)

General information

Class/mechanism (from NCI Drug Dictionary): The orally bioavailable mesylate salt of masatinib, a multi-targeted protein tyrosine kinase inhibitor with potential antineoplastic activity. Masitinib selectively binds to and inhibits both the wild-type and mutated forms of the stem cell factor receptor (c-Kit; SCFR); platelet-derived growth factor receptor (PDGFR); fibroblast growth factor receptor 3 (FGFR3); and, to a lesser extent, focal adhesion kinase (FAK).
Route: PO
