PURPOSE To evaluate the maximum tolerated regimen (MTR), dose-limiting toxicities, and pharmacokinetics of pazopanib, an oral small-molecule tyrosine kinase inhibitor of vascular endothelial growth factor receptor, platelet-derived growth factor receptor, and c-Kit, in combination with paclitaxel. PATIENTS AND METHODS Pazopanib was given daily with weekly(More)
This phase I, open-label, dose-escalation study assessed the maximum-tolerated dose, safety, pharmacokinetics, and preliminary antitumor activity of pazopanib plus lapatinib combination therapy in patients with solid tumors. Patients were to take pazopanib and lapatinib orally once daily in a fasting condition. During the escalation phase, pazopanib and(More)
Pazopanib, an oral inhibitor of vascular endothelial growth factor receptor, platelet-derived growth factor receptor, and c-kit kinases, inhibits multiple cytochrome P450 (CYP450) enzymes in vitro. This study in patients with advanced cancer evaluated the effect of pazopanib on CYP450 function by comparing the pharmacokinetics of CYP-specific probe drugs in(More)
Pazopanib is an oral angiogenesis inhibitor of vascular endothelial growth factor (VEGF) receptor, platelet-derived growth factor receptor, and cytokine receptor. This open-label, randomized, crossover, phase I study evaluated the effect of low- and high-fat meals on the pharmacokinetics (PK) of pazopanib in patients with advanced solid tumors. Patients(More)
3561 Background: Patients (pts) with advanced hepatocellular carcinoma (HCC) have a poor prognosis. HCC is a highly vascular tumor with increased levels of angiogenic factors including VEGF and VEGFR. Pazopanib (GW786034) is an oral angiogenesis inhibitor targeting VEGFR, PDGFR, and c-Kit. A Phase I study was conducted to determine the maximum tolerated(More)
PURPOSE Coadministration of morphine with oral gabapentin has been shown to increase plasma gabapentin concentrations. This study evaluated whether there was any interaction between gabapentin enacarbil (GEn), which is a prodrug of gabapentin, and morphine in terms of pharmacokinetics, pharmacodynamics, safety, and tolerability. METHODS This randomized,(More)
Anzemet (dolasetron mesylate) is being developed for the prevention of chemotherapy-induced emesis and postoperative nausea and vomiting. Twenty-four healthy male subjects were orally dosed with dolasetron mesylate, 200 mg, after either an overnight fast or a high-fat breakfast. The ratio of the mean area under the plasma concentration-time curve of the(More)
BACKGROUND Gabapentin enacarbil (GEn) is a prodrug of gabapentin and is approved in the United States in adults for the management of postherpetic neuralgia and in the United States and Japan for the treatment of moderate-to-severe primary restless legs syndrome. OBJECTIVE This study examined the lack of effect of GEn on cardiac repolarization in(More)
In this first part of a two-part investigation, the intravenous dose proportionality of dolasetron mesylate, a 5-HT3 receptor antagonist, and the absolute bioavailability of oral dolasetron mesylate were investigated. In an open-label, randomized, four-way crossover design, 24 healthy men between the ages of 19 and 45 years received the following doses: 50,(More)
