Filter by:Idiopathic pulmonary fibrosis (IPF) is an illness characterized by progressive decline in lung function and premature death from respiratory failure. Fibrocytes are a novel population of bone marrow-derived circulating progenitor cells that have been shown to traffic to the lungs and contribute to fibrosis in animal models of pulmonary fibrosis, and whose numbers correlate with the degree of fibrosis and with survival in human pulmonary fibrosis. The investigators propose to test the hypothesis that therapy with the mTOR inhibitor, sirolimus, reduces the number of circulating fibrocytes in patients with IPF. The investigators propose to test this hypothesis in short-term pilot trial of sirolimus in patients with IPF to determine its effect on the number and phenotype of circulating fibrocytes.
The goal of IMPROV is to identify molecular mechanisms that contribute to lung injury and long-term breathing problems in preterm infants by investigating two interrelated biochemical pathways: the urea cycle-nitric oxide pathway and the glutathione pathway. The investigators hypothesize that prematurity-related limitations in the function of these important biochemical pathways contribute to respiratory disease risk over the first year of life.
The purpose of the study is to determine a possible association between the clinical entity of exacerbation, markers of systemic inflammation and endothelial dysfunction in patients with COPD.
The primary objective of this observational study is to determine the incidence of medically attended (inpatient or outpatient) acute respiratory illnesses or events leading to worsening cardiorespiratory status (ie, acute exacerbations of chronic obstructive pulmonary disease [AECOPD] or worsening CHF) associated with RSV infections in high-risk adults (ie, those with severe COPD and/or advanced CHF) across multiple consecutive RSV seasons.
Chronic obstructive pulmonary disease (COPD) is one of the commonest respiratory diseases. During the early stage of COPD, patients only have mild respiratory symptoms or signs which may lead to under-diagnosis of the disease. Patients may show poor response to treatment at later stages of the disease, associated with higher mortality and incidence of re-hospitalization and disability causing burden for both the families and the society. So far, there is no large-scale clinical trial on long-term intervention with tiotropium bromide (Spiriva) in patients with early stages of COPD (i.e. GOLD Stage I-II COPD or asymptomatic COPD). It would be of great significance for COPD prevention and treatment if the investigators could prove that tiotropium decreases the lung function decline and reverses disease progression in patients with early-stage COPD. The investigators objective is to evaluate the efficacy of long-term intervention with tiotropium in early stage (FEV1 ≥50% predicted) COPD (difference of trough FEV1, number of exacerbations, time to first exacerbation, quality of life, etc) and relevant pharmacoeconomic endpoints.
This is a Phase I study to assess the combined effects of food and suppression of gastric acid secretion on the relative bioavailability of an immediate release (IR) tablet formulation and prototype bioenhanced formulations of GSK1325756, an oral interleukin 8 receptor (IL8R also known as CXCR2) antagonist. The objectives are to understand if the co-administration of food enhances absorption and the inter-subject variability for the current GSK1325756 IR tablet under fed state proton pump inhibitor (PPI) conditions and secondly to assess whether two proposed bioenhanced formulations offer any improvement over the current GSK1325756 IR formulation under PPI conditions. This open-label, randomized, 5-period crossover study will be completed in a single cohort of subjects, with an interim analysis after completion of Treatment Period 4. During Treatment Periods 1 to 4, subjects will be randomized to receive GSK1325756 50 mg IR in the fed state, GSK1325756 50 mg IR in the fasted state, GSK1325756 Bioenhanced Formulation 1 in the fasted state, and GSK1325756 Bioenhanced Formulation 2 in the fasted state. Progression to Treatment Period 5 and the choice of bioenhanced formulation for dosing in this treatment period will be dependent on the findings of an interim analysis of the pharmacokinetic profile and relative bioavailability of each formulation following completion of Treatment Periods 1 to 4. In Treatment Period 5, subjects will receive the selected GSK1325756 bioenhanced formulation in the fed state.
In the current study GSK961081 and fluticasone propionate will be administered in a blended formulation from a single device and compared with GSK961081 and fluticasone propionate administered alone and concurrently. This is a single centre, randomized, double-blind, double dummy, single dose, four way cross-over study investigating the pharmacokinetics and pharmacodynamics of GSK961081 and fluticasone propionate when administered alone, concurrently and as a combination blend in healthy subjects.
A Phase 2 Double-blind, Placebo-controlled Study to Evaluate the Efficacy of MEDI8968 in Chronic Obstructive Pulmonary Disease
To demonstrate the additional benefit of roflumilast when added on to fixed-dose combination (FDC) LABA/ICS in the reduction of exacerbations in subjects with severe to very severe COPD.
HYPID study is an observational and prospective study of patients with interstitial lung disease and pre capillary hypertension diagnosed by right heart sided catheterization. The primary aim of the study is to identify prognostic factors.
