bms-690514

Description: BMS-690514 is a novel, potent and orally bioavailable inhibitor of EGFR human epidermal growth factor receptor (HER) 1 and VEGFR (vascular endothelial growth factor receptors) with IC50s of 5, 20 and 60 nM for EGFR, HER 2 and HER 4, respectively. BMS-690514 is currently under investigation as an oral agent for the treatment of solid tumors. In vitro and in vivo studies were conducted to characterize the pharmacokinetics and metabolism. Through integration of in vitro and in vivo pharmacokinetic data and antitumor efficacy in nude mice, human pharmacokinetics and efficacious doses were projected for BMS-690514. The oral bioavailability of BMS-690514 was 78% in mice, approximately 100% in rats, 8% in monkeys, and 29% in dogs. The low oral bioavailability in monkeys could be attributed to high systemic clearance in that species, which was also consistent with predicted clearance using in vitro data from monkey liver microsomes. The preclinical ADME properties of BMS-690514 suggest good oral bioavailability in humans and metabolism by multiple pathways including oxidation and glucuronidation.
