Vilanterol (VI; GW642444M) is a novel inhaled long-acting β2-agonist with inherent 24 h activity in vitro in development as a combination with the inhaled corticosteroid fluticasone furoate for both COPD and asthma. These studies were conducted to determine the safety, tolerability, pharmacodynamics and pharmacokinetics of VI in healthy subjects and(More)
BACKGROUND Very late antigen (VLA-4) antagonists have been proposed as potential therapies for diseases in which cell recruitment and accumulation are causative. Asthma, which is characterized by airway inflammation involving the accumulation of eosinophils and mononuclear cells, is one such disease. OBJECTIVE We sought to assess the effect of IVL745, a(More)
Purpose: To investigate the effects of single doses of losmapimod, dilmapimod (inhibitors of p38 MAPK) and prednisolone on biomarkers of systemic inflammation (serum C-reactive protein (CRP) and interleukin (IL)-6) in subjects with active rheumatoid arthritis (RA). Methods: Two randomized, double blind, placebo controlled, parallel group, single dose(More)
Exercise-induced bronchoconstriction (EIB) describes the condition whereby exercise causes airflow obstruction that lasts for up to 90 minutes without treatment. This double-blind, placebo-controlled, five-way crossover study investigated the dose response and duration of action of a 5-lipoxygenase-activating protein inhibitor, GSK2190915, to inhibit EIB in(More)
AIM To compare antisecretory effects of rabeprazole and esomeprazole after single and repeat dosing in Helicobacter pylori-negative healthy volunteers. METHODS Results were pooled from three smaller, open, crossover, randomized studies to obtain data from 80 subjects. The studies compared: (a) 5 days' dosing of 20 mg rabeprazole and esomeprazole (n = 24);(More)
GSK961081 is an inhaled bi-functional molecule with both muscarinic antagonism and β2-agonism (MABA) properties. This randomised, double-blind, double-dummy, crossover study evaluated 14 days treatment with the MABA GSK961081 400 μg and 1200 μg once daily and tiotropium 18 μg once daily plus salmeterol 50 μg twice daily (TIO + SAL), versus placebo in 50(More)
BACKGROUND GSK2190915, a potent 5-lipoxygenase-activating protein inhibitor, prevents the synthesis of leukotrienes and 5-oxo-6,8,11,14-eicosatetraenoic acid (5-oxo-ETE). OBJECTIVE To assess the effect of GSK2190915 on the allergen-induced asthmatic responses. METHODS Nineteen eligible male subjects with mild asthma were enrolled in and completed this(More)
BACKGROUND There are few data on the bronchodilatory effects of adding short-acting bronchodilators (SABA) to maintenance, long-acting bronchodilator therapy. This study assessed the additional bronchodilation and safety of adding supratherapeutic doses of salbutamol (SALB) or ipratropium bromide (IPR) to the novel bi-functional molecule (or dual(More)
OBJECTIVE To investigate the pharmacokinetics and pharmacodynamics of inhaled GSK961081 and fluticasone propionate (FP) given alone, concurrently and as a combination blend formulation. METHODS The study was double-blind, double-dummy, four-way crossover. Twenty-four healthy volunteers took single doses of the following in randomized order: (1) GSK961081(More)
BACKGROUND GSK2190915, a 5-lipoxygenase activating protein inhibitor, inhibits the production of cysteinyl leukotrienes and leukotriene B4 and 5-oxo-6,8,11,14-eicosatetraenoic acid. We have previously reported that GSK2190915 100 mg daily inhibits early and late asthmatic responses to inhaled allergen; the effects of lower doses have not been reported. This(More)
