The pharmacokinetics, metabolism, and excretion of dolutegravir, an unboosted, once-daily human immunodeficiency virus type 1 integrase inhibitor, were studied in healthy male subjects following single oral administration of [(14)C]dolutegravir at a dose of 20 mg (80 μCi). Dolutegravir was well tolerated, and absorption of dolutegravir from the suspension(More)
GSK1265744 (GSK744) is an integrase strand-transfer inhibitor that has been formulated as a long-acting (LA) injectable suitable for monthly to quarterly clinical administration. GSK744 LA was administered at two time points 4 weeks apart beginning 1 week before virus administration, and macaques were challenged weekly for 8 weeks. GSK744 LA, at plasma(More)
1.  Cabotegravir [(3S,11aR)-N-[(2,4-difluorophenyl)methyl]-6-hydroxy-3-methyl-5,7-dioxo-2,3,5,7,11,11a-hexahydro[1,3]oxazolo[3,2-a]pyrido[1,2-d]pyrazine-8-carboxamide] is an HIV-1 integrase inhibitor under development as a tablet for both oral lead-in therapy and long-acting (LA) injectable for intramuscular dosing. 2. Metabolism, pharmacokinetics and(More)
This first-time-in-human, randomized, double-blind, placebo-controlled, dose-escalation study assessed the safety, tolerability, pharmacokinetics, and antiviral activity of GSK2485852, a hepatitis C virus (HCV) NS5B inhibitor, in 27 chronically infected HCV genotype-1 subjects. Subjects received GSK2485852 70, 420, and 70 mg with a moderate fat/caloric(More)
Type 1 diabetes mellitus is caused by severe insulin deficiency secondary to the autoimmune destruction of pancreatic beta cells. Patients need to be controlled by periodic insulin injections to prevent the development of ketoacidosis, which can be fatal. Sustained, low-level expression of the rat insulin 1 gene from the liver of severely diabetic rats was(More)
1. Plasma clearance of dolutegravir, an unboosted HIV-1 integrase inhibitor, was low in rat and monkey (0.23 and 2.12 mL/min/kg, respectively) as was the volume of distribution (0.1 and 0.28 L/kg, respectively) with terminal elimination half-life approximately 6 h. Dolutegravir was rapidly absorbed from oral solution with a high bioavailability in rat and(More)
GW695634 is the prodrug of GW678248, a novel non-nucleoside reverse transcriptase inhibitor with potent antiviral activity against HIV/AIDS efavirenz- and nevirapine-resistant viruses. In mice, rats, and monkeys following oral administration of [(14)C]GW695634, the primary pathway of metabolic clearance was by amide hydrolysis and the main route of(More)
