About XL647
XL647 is a potent inhibitor of receptor tyrosine kinases (RTKs) that are implicated in driving tumor proliferation and vascularization (blood vessel formation). XL647 inhibits EGFR, HER2 and VEGFR2. The compound has been optimized for high potency and oral bioavailability (using in vivo systems), demonstrates excellent activity in target-specific cellular functional assays and has shown sustained inhibition of target RTKs preclinically in vivo following a single oral dose. Two phase 2 trials in patients with NSCLC are ongoing.
