Description

XL820 is investigated for use/treatment in solid tumors. XL820 is a solid. The proteins that XL820 inhibit include platelet-derived growth factor receptor beta (PDGFR), mast/stem cell growth factor receptor KIT, vascular endothelial growth factor receptor 2, and platelet-derived growth factor receptor alpha, clinically validated targets implicated in a variety of human cancers. XL820 exhibits dose-dependent growth inhibition in models of breast carcinoma, gliomas and leukemia.

Mechanism of action

XL820 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.
