Temozolomide, an oral DNA methylator that inactivates the DNA repair enzyme O6-alkylguanine-DNA alkyltransferase (AGAT), has demonstrated anticancer activity on protracted schedules. Protracted schedules may lead to an ‘autoenhancement’ of temozolomide's inherent cytotoxic potential by cumulative reduction of the cell's capacity for AGAT-mediated DNA repair(More)
Purpose To study the influence of repeated oral administration of ketoconazole, a potent CYP3A4 inhibitor, on the plasma pharmacokinetics of eribulin mesylate administered by single-dose intravenous infusion. Eribulin mesylate is a non-taxane microtubule dynamics inhibitor that is currently under development in phase I-III trials for the treatment of solid(More)
1. Temozolomide, an imidazotetrazine derivative, is a cytotoxic alkylating agent of broad-spectrum antitumour activity. The absorption, metabolism, distribution and excretion of temozolomide have been investigated in male and female Sprague-Dawley and Long-Evans rats following single oral or intravenous dose administration of 200 mg m(-2) non-radiolabelled(More)
SCH351591, a novel phosphodiesterase-4 inhibitor under investigation as a potential therapeutic for asthma and chronic obstructive pulmonary disease (COPD), was evaluated in a 3-month rising-dose study in Cynomolgus monkeys. Four groups, containing four monkeys/sex, received vehicle control or rising doses up to 12, 24, or 48 mg/kg of SCH351591 daily.(More)
The aim of this study was to determine the plasma pharmacokinetics of eribulin mesylate in patients with solid tumors with mild and moderate hepatic impairment. A phase I, pharmacokinetic study was performed in patients with advanced solid tumors and normal hepatic function or Child-Pugh A (mild) or Child-Pugh B (moderate) hepatic impairment. Treatments(More)
Background Several cancer therapies can prolong cardiac repolarization. This study assessed the potential of eribulin to affect cardiac repolarization in patients with advanced solid tumors. Methods In this Phase I, open-label, single-arm study, patients received eribulin mesylate (1.4 mg/m2; Days 1 and 8 of a 21-day cycle). The primary objective was to(More)
AIM Eribulin mesylate is a non-taxane microtubule dynamics inhibitor that was recently approved for treatment of metastatic breast cancer. The aim of this study was to determine the effect of rifampicin, a CYP3A4 inducer, on the plasma pharmacokinetics of eribulin in patients with solid tumours. METHODS An open-label, non-randomized phase I study was(More)
Purpose. To characterize the pharmacokinetic and tissue distribution profiles of a nucleotide-based thrombin inhibitor (GS522, phosphodiester oligonucleotide, GGTTGGTGTGGTTGG) following intravenous administration to rats. Methods. Pharmacokinetic study: 10 mg/kg, 20 mg/kg, 30 mg/kg (6 animals/dose) were administered to rats by rapid injection into the(More)
OBJECTIVE Ezetimibe is a novel lipid-lowering drug that prevents intestinal absorption of dietary and biliary cholesterol leading to significant reduction in total-C, LDL-C, Apo B, and TG and increases in HDL-C in patients with hypercholesterolemia. Gemfibrozil, a fibric acid derivative, is an effective lipid-modulating agent that increases serum(More)
The quantitative determination of short (< 20 bases) single-standed (ss-) oligonucleotides (oligos) from blood plasma using capillary gel electrophoresis with laser-induced fluorescence is reported. Oligos were derivatized on column after equilibration of the column with a 1:150 dilution of OliGreen dye. The resulting fluorescent complex was detected and(More)
