Background Axitinib is an oral, potent and selective inhibitor of vascular endothelial growth factor receptors (VEGFRs) 1, 2 and 3. We report on data obtained from 18 Japanese patients with advanced solid tumors in two phase I trials that evaluated the safety, pharmacokinetics and antitumor activity of axitinib and also examined potential biomarkers.(More)
[reaction: see text] A new strategy directed toward the total synthesis of stachyflin, a potent and novel anti-influenza A virus agent isolated from a microorganism, has been presented through the enantioselective synthesis of the tetracyclic core structure. The synthetic method features a BF(3) x Et(2)O-induced domino(More)
INTRODUCTION Drug transporter proteins are expressed on the cell membrane, regulating substrate exposure in systemic circulation and/or peripheral tissues. Genetic polymorphism of drug transporter genes encoding these proteins could alter the functional activity and/or protein expression, having effects on absorption, distribution, metabolism and excretion(More)
Axitinib, a potent and selective tyrosine kinase inhibitor of vascular endothelial growth factor receptors 1, 2, and 3, showed improved progression-free survival over sorafenib in patients previously treated for advanced renal cell carcinoma in the AXIS trial. Although a few studies had established the efficacy and safety of axitinib in Asian patients,(More)
Drug transporters, together with drug metabolic enzymes, are major determinants of drug disposition and are known to alter the response to many commonly used drugs. Substantial frequency differences for known variants exist across geographic regions for certain drug transporters. To deliver efficacious medicine with the right dose for each patient, it is(More)
PURPOSE These studies evaluate the relative bioavailability of crushed apixaban tablets and the effect of food on apixaban pharmacokinetic properties. METHODS An open-label, randomized, crossover study in 33 healthy adults compared the bioavailability of 2 × 5-mg apixaban tablets administered whole (reference), crushed and suspended in 30 mL of water, and(More)
Preclinical studies suggest that ALK-1 signaling mediates a complementary angiogenesis pathway activated upon development of resistance to vascular endothelial growth factor (VEGF)-targeted therapies. Inhibition of ALK-1 signaling may lead to disruption of tumor angiogenesis and growth. We report findings from a multicenter, open-label, phase I study of the(More)
According to the US Food and Drug Administration, pharmacometrics is an emerging science that quantifies drugs, diseases, and trial information to aid efficient drug development and/or regulatory decisions. Quantitative decision making occurs at all stages of drug development. In general, patient-level data are not made available to competitors. However,(More)
