A phase I study of AST1306, a novel irreversible EGFR and HER2 kinase inhibitor, in patients with advanced solid tumors

Background AST1306 is an orally active irreversible small molecule inhibitor of EGFR (erbB1), HER2 (erbB2) and HER4 (erbB4) signaling. This is a phase I, open-label, dose-escalation study to evaluate the safety and tolerability, pharmacokinetics (PK), and preliminary anti-tumor effects of oral AST1306. In addition the effects of food on PK was tested.
