OBJECTIVE To evaluate the efficacy, safety, and tolerability of incremental doses of albiglutide, a long-acting glucagon-like peptide-1 receptor agonist, administered with three dosing schedules in patients with type 2 diabetes inadequately controlled with diet and exercise or metformin monotherapy. RESEARCH DESIGN AND METHODS In this randomized(More)
AIMS Albiglutide is a glucagon-like peptide-1 (GLP-1) mimetic generated by genetic fusion of a dipeptidyl peptidase-IV-resistant GLP-1 dimer to human albumin. Albiglutide was designed to retain the therapeutic effects of native GLP-1 while extending its duration of action. This study was conducted to determine the pharmacokinetics and initial(More)

Opioid neurotransmission has a key role in mediating reward-related behaviours. Opioid receptor (OR) antagonists, such as naltrexone (NTX), can attenuate the behaviour-reinforcing effects of primary (food) and secondary rewards. GSK1521498 is a novel OR ligand, which behaves as an inverse agonist at the μ-OR sub-type. In a sample of healthy volunteers, we(More)
The opioid system is implicated in the hedonic and motivational processing of food, and in binge eating, a behaviour strongly linked to obesity. The aim of this study was to evaluate the effects of 4 weeks of treatment with the mu-opioid receptor antagonist GSK1521498 on eating behaviour in binge-eating obese subjects. Adults with body mass index ⩾30 kg m−2(More)
Purpose. This study was conducted to assess the pharmacokinetics and pharmacodynamics of 7-nitroindazole (7-NI), a selective inhibitor of neuronal nitric oxide synthase (NOS). Methods. Male Sprague-Dawley rats were equipped with peritoneal/venous cannulae and a microdialysis probe in the hippocampal cortex. Rats received 7-NI in peanut oil (25 mg/kg) ip(More)
1. This work investigated the drug interaction potential of GSK1292263, a novel GPR119 agonist, with the HMG-coA reductase inhibitors simvastatin and rosuvastatin. 2. In vitro experiments assessed the inhibition of transporters and CYP enzymes by GSK1292263, and a clinical drug interaction study investigated the effect of GSK1292263 (300 mg BID) on the(More)
AIMS Albiglutide is a glucagon-like peptide-1 analog that is currently under investigation for the treatment of type 2 diabetes mellitus as a once-weekly injection. Three open-label phase 1 studies were conducted in healthy human participants to investigate potential pharmacokinetic (PK) and/or pharmacodynamic (PD) interactions between albiglutide and(More)
CONTEXT Native glucagon-like peptide-1 increases insulin secretion, decreases glucagon secretion, and reduces appetite but is rapidly inactivated by dipeptidyl peptidase-4. Albiglutide is a novel dipeptidyl peptidase-4-resistant glucagon-like peptide-1 dimer fused to human albumin designed to have sustained efficacy in vivo. OBJECTIVES The objectives were(More)
2004 Background: The mitotic kinesin KSP plays an exclusive and essential role in assembly and function of the mitotic spindle. KSP represents a novel target for development of therapeutics against cancer. SB-715992 is a unique and selective inhibitor of KSP, that is preferentially overexpressed in malignant cells, functions exclusively in mitosis, and is(More)
