Mechanism of actionXL820 inhibits KIT as well as VEGFR2 and PDGFR, clinically validated targets implicated in a variety of human cancers. In tumor models of breast carcinoma, glioma and leukemia, the compound exhibited dose-dependent growth inhibition and has been shown to cause tumor regression. XL820 demonstrated excellent activity in target-specific cellular functional assays. In biochemical and cellular assays, XL820 potently inhibits mutant forms of KIT that confer resistance to approved KIT inhibitors. XL820 has good oral bioavailability and has shown sustained inhibition of target RTKs in vivo following a single oral dose.
