The treatment of acute leukaemias, which are the most common paediatric cancers, has improved considerably in recent decades, with complete response rates approaching approximately 90% in some cases. However, there remains a major need for treatments for patients who do not achieve or maintain complete remission, for whom the prognosis is very poor. In this(More)
PURPOSE The receptors for hepatocyte and vascular endothelial cell growth factors (MET and VEGFR2, respectively) are critical oncogenic mediators in gastric adenocarcinoma. The purpose is to examine the safety and efficacy of foretinib, an oral multikinase inhibitor targeting MET, RON, AXL, TIE-2, and VEGFR2 receptors, for the treatment of metastatic(More)
Clofarabine for injection is a second-generation nucleoside analog approved in the United States (Clolar®) and Europe (Evoltra®) for the treatment of pediatric relapsed or refractory acute lymphoblastic leukemia. This report describes the population pharmacokinetics of clofarabine and its metabolite 6-ketoclofarabine in adult and pediatric patients with(More)
PURPOSE To determine the safety, tolerability, and pharmacokinetics and to seek preliminary evidence of anticancer activity of tasidotin (ILX651), a novel dolastatin analogue, when administered as a 30-minute i.v. infusion weekly for 3 weeks every 4 weeks. EXPERIMENTAL DESIGN Thirty patients with advanced solid malignancies were treated with 82 courses at(More)
Eliglustat tartrate (Genz-112638), a specific inhibitor of glucosylceramide synthase, is under development as an oral substrate reduction therapy for Gaucher disease type 1 (GD1). A multinational, open-label, single-arm phase 2 study of 26 GD1 patients (16 female, 10 male; mean age, 34 years) evaluated the efficacy, safety, and pharmacokinetics of(More)
Purpose. To demonstrate how correlations among predictor variables in a population pharmacokinetic model affect the ability to discern which covariates should enter into the structural pharmacokinetic model. Methods. Monte Carlo simulation was used to generate multiple-dose concentration-time data similar to that seen in a Phase III clinical trial. The(More)
PURPOSE To determine the maximum tolerated dose (MTD), dose-limiting toxicity (DLT), and pharmacokinetics of tasidotin (ILX651), a dolastatin-15 analogue, when administered on days 1, 3, and 5 every 3 weeks in patients with advanced solid tumors. PATIENTS AND METHODS Thirty-two patients were treated with 92 courses of tasidotin through seven dose levels(More)
We investigated the effect of amphetamine pretreatment on the locomotor response to subsequent cocaine challenge. Rats were administered either 0.75 mg/kg amphetamine in a testing environment and saline in their home cage, saline in the testing environment and 0.75 mg/kg amphetamine in their home cage, or saline in both the testing environment and home(More)
The population pharmacokinetics of plasma clofarabine and intracellular clofarabine triphosphate were characterized in pediatric patients with acute leukemias. Traditional model-building techniques with NONMEM were used. Covariates were entered into the base model using a forward selection significance level of .05 and a backwards deletion criterion of(More)
The distribution, metabolism, and elimination of intravenous [14C]clofarabine was studied in Fischer 344 male rats under a once daily for 5 days dosing schedule of 25 or 50 mg/kg/day. Also, the in vitro metabolism in rat, dog, and human hepatocytes was studied. Plasma radioactivity (of which clofarabine accounted for 63% to 93%) exhibited three phases of(More)
