Filter by:The purpose of the study is to investigate the tolerability and safety of AZD2423 in Patients with chronic obstructive pulmonary disease.
The purpose of this pilot study is to evaluate the effect of high intensity non-invasive positive pressure ventilation (HINPPV) for stable, hypercapnic COPD patients. The investigators believe that HINPPV, used at least 6 hours nocturnally over three months, will benefit the stable hypercapnic COPD patient through a reduction in the daytime partial pressure of carbon dioxide in arterial blood (PaCO2) levels.
Exacerbations are important events in the natural history of chronic obstructive pulmonary disease (COPD). Beside the acute (and prolonged) clinical impact, there is evidence that exacerbations negatively affect the natural history of the disease; e.g. lung function decline is accelerated in patients with frequent exacerbations. Bacteria are considered the most relevant cause of exacerbations, but there is evidence that viral infections are equally contributing. Either alone or in combination with viruses, airway bacterial load in stable COPD correlates with both the frequency of exacerbations and the decline in lung function. A long-term clinical trial recently showed that the regular treatment with inhaled corticosteroids (ICS) increases the risk of infectious events such as pneumonia, whereas it reduces the frequency of acute COPD exacerbations in COPD. In a recent study it was found that airway bacterial load increases over time (1 yr follow up) in stable COPD. In this study, virtually all patients (93%) were treated with ICS. This study is designed to evaluate whether long-term (1 year) ICS treatment increases viral and/or bacterial load in the sputum of COPD patients.
In the present study, the investigators wish to address the effect of a glucocorticoid/long-acting beta-agonist preparation on endothelial function in COPD patients who do not currently smoke (ex-smokers) by measuring endothelium-dependent (albuterol response) and endothelium-independent (NTG response) vasodilation in the bronchial artery, reflecting endothelium-dependent and endothelium-independent vasodilation (drug-induced increase in Qaw, ΔQaw). With this approach the investigators will test the hypothesis that in stable ICS-naïve COPD patients, endothelium-dependent vasodilation is restored with a glucocorticoid/long-acting beta-agonist preparation, presumably resulting from the glucocorticoid component.
The purpose of this study is to investigate effects of inhaled AZD8683 compared to placebo in COPD patients.
Aspects of confocal laser micro-endoscopy (CLME) and morphometry in chronic obstructive pulmonary disease (COPD) and lung transplant recipients is described and will be correlated with clinical findings in order to described small airway remodelling in these patients.
The objective of this study is to evaluate the effect of the combination of formoterol and beclometasone dipropionate on central and peripheral airway dimensions in COPD patients using Computational Fluid Dynamics (CFD). Further more, the effect of this combination therapy on lung function (spirometry, body plethysmography), the BODE index, COPD assessment test (CAT) and Borg CR10 scale will be assessed and the safety will be evaluated.
The purpose of this study is to provide pivotal efficacy and safety data for QVA149 in patients with moderate to severe COPD.
This study will investigate if adding a domiciliary respiratory physiotherapy treatment to standard care in patients with chronic obstructive pulmonary disease (COPD) can improve physical function (walking test) and quality of life.
The investigators hypothesise that phosphodiesterase 5A inhibitors will improve exercise capacity in those with Chronic Obstructive Pulmonary Disease and secondary pulmonary hypertension.
