BACKGROUND Hyperglycaemia is associated with serious complications, significant morbidity and death. Despite the availability of a wide range of therapeutic options, many patients with diabetes mellitus fail to achieve or maintain recommended glycaemic goals. Ipragliflozin (ASP1941) is a novel, selective inhibitor of the sodium-dependent glucose(More)
OBJECTIVE Ipragliflozin, a sodium-glucose cotransporter 2 inhibitor, stimulates glycosuria and lowers glycemia in patients with type 2 diabetes (T2DM). The objective of this study was to assess the pharmacodynamics of ipragliflozin in T2DM patients with impaired renal function. RESEARCH DESIGN AND METHODS Glycosuria was measured before and after a single(More)
Gemcitabine is frequently used in the treatment of patients with solid tumors. Gemcitabine is taken up into the cell via human nucleoside transporters (hNTs) and is intracellularly phosphorylated by deoxycytidine kinase (dCK) to its monophosphate and subsequently into its main active triphosphate metabolite 2',2'-difluorodeoxycytidine triphosphate (dFdCTP),(More)
Gemcitabine triphosphate (dFdCTP) is a highly active metabolite of gemcitabine. It is formed intra-cellularly via the phosphorylation of gemcitabine by deoxycytidine kinase. The monitoring of dFdCTP in human peripheral blood mononuclear cells (PBMCs), in addition to plasma concentrations of gemcitabine and its metabolite 2',2'-difluorodeoxyuridine, is(More)
PURPOSE To determine the toxicity, tolerability, pharmacokinetics, pharmacodynamics, and preliminary antitumor activity of oral gemcitabine (2',2'-difluorodeoxycytidine; dFdC) in patients with cancer. EXPERIMENTAL DESIGN Patients with advanced or metastatic cancer refractory to standard therapy were eligible. Gemcitabine was administered p.o. starting at(More)
In a clinical study with oral gemcitabine (2',2'-difluorodeoxycytidine, dFdC), we found that gemcitabine was hepatotoxic and extensively metabolized to 2',2'-difluorodeoxyuridine (dFdU) after continuous oral dosing. The main metabolite dFdU had a long terminal half-life after oral administration. Our hypothesis was that dFdU and/or phosphorylated(More)
PURPOSE To investigate i.v. administration of delimotecan (MEN 4901/T-0128), a carboxymethyldextran polymer prodrug of the active camptothecin derivative T-2513, and to assess the maximum tolerated dose, safety profile, clinical pharmacology, and antitumor activity of delimotecan and metabolites. EXPERIMENTAL DESIGN Patients with solid tumors refractory(More)
To explore the parmacokinetics, safety and tolerability of paclitaxel after oral administration of SMEOF#3, a novel Self-Microemulsifying Oily Formulation, in combination with cyclosporin A (CsA) in patients with advanced cancer. Seven patients were enrolled and randomly assigned to receive oral paclitaxel (SMEOF#3) 160 mg+CsA 700 mg on day 1, followed by(More)
AIMS To investigate the effect of ipragliflozin on the pharmacokinetics of sitagliptin, pioglitazone or glimepiride and vice versa in healthy subjects. METHODS Three trials with an open-label, randomized, two-way crossover design were conducted in healthy subjects. Ipragliflozin 150 mg, sitagliptin 100 mg, pioglitazone 30 mg or glimepiride 1-2 mg were(More)
