PURPOSE Barasertib (AZD1152) is a pro-drug that rapidly undergoes phosphatase-mediated cleavage in serum to release barasertib-hQPA, a selective Aurora B kinase inhibitor that has shown preliminary activity in clinical studies of patients with acute myeloid leukemia (AML). The pharmacokinetic (PK), metabolic and excretion profiles of barasertib and(More)
BACKGROUND Vandetanib, an inhibitor of vascular endothelial growth factor receptor 2 (VEGFR-2), epidermal growth factor receptor (EGFR), and rearranged during transfection (RET), is a developmental oncology drug, that is in part metabolized by cytochrome P450 (CYP) 3A4. Clinical studies were performed to assess the potential for 3A4 inhibitors and inducers(More)
After intravenous injection of therapeutic doses of bleomycin only small amounts could be measured in glioma tissue obtained at operation in patients with malignant gliomas and the drug was rapidly cleared from the blood (T1/2 = 2 hrs). Negatively charged liposomes injected through Ommaya reservoirs into the glioma tumour bed were tolerated without(More)
BACKGROUND Fostamatinib (R788) is a spleen tyrosine kinase (SYK) inhibitor. The active metabolite of fostamatinib, R406, is primarily metabolized by CYP3A4. OBJECTIVES The aim of this study was to characterize hepatic microsomal metabolism of R406 and confirm the role of CYP3A4 in R406 metabolism, determining whether co-administration of CYP3A4 inhibitors(More)
BACKGROUND AND OBJECTIVES Fostamatinib is a spleen tyrosine kinase inhibitor that has been investigated as therapy for rheumatoid arthritis and immune thrombocytopenic purpura. The present studies assessed the potential for pharmacokinetic interaction between fostamatinib and the commonly prescribed medications oral contraceptive (OC), warfarin, and statins(More)
BACKGROUND Zibotentan (ZD4054) is a specific endothelin A (ETA) receptor antagonist being investigated for the treatment of prostate cancer. As zibotentan is eliminated by renal and metabolic routes, clearance may be reduced in patients with hepatic or renal impairment, leading to greater drug exposure. METHODS Open-label studies investigated the PK and(More)
