Filter by:This is a 52-week treatment, multi-center, randomized, open label, parallel group study to assess the long term safety and tolerability of once-daily QVA149 (indacaterol and NVA237 ([glycopyrronium bromide]) using tiotropium as an active control in Japanese patients with moderate to severe chronic obstructive pulmonary disease (COPD).
Chronic obstructive pulmonary disease (COPD) is a progressive and largely irreversible lung disease characterized by chronic bronchitis and/or emphysema, resulting in breathlessness, cough and sputum. As COPD progresses, patients experience increasing deterioration of their health-related quality of life, with greater impairment in their ability to work and declining participation in social and physical activities. The aim of this non-interventional study is to evaluate data on quality of life in COPD patients in Germany in a real life medical setting under therapy with the phosphodiesterase-inhibitor (PDE-4) roflumilast (Daxas). Evaluation is based on two COPD specific questionnaires to assess the patient`s health status over six months. During the study, lung function measurements such as spirometry will be conducted according to common medical standard. Daxas (tablet) will be administered once daily. The study will provide further data on the safety and tolerability of Daxas.
AZD2115 Single Ascending Dose Study
Regular exercise can help patients with the lung disease, chronic obstructive pulmonary disease (COPD). But COPD patients have a hard time with training because of their breathing. To improve their program they can train with one leg at a time. Another way is to make their exercise easier by breathing helium. Putting two methods, one-legged and helium, together may improve their program even more. This project is planned to assess whether breathing helium improves their one-legged exercise endurance. If it does, then there may be a reason for combining one-legged exercise with breathing helium as part of their respiratory rehabilitation program. The aim of this study is to determine whether breathing helium-hyperoxia enables a further increase in the constant power endurance time during one-legged exercise in ventilatory limited subjects with COPD. The null hypothesis is that patients will have sufficient peripheral muscle limitation that ventilatory unloading using helium-hyperoxia will be of no additional benefit to exercise tolerance. The investigators hypothesize that patients with COPD are so ventilatory limited relative to their peripheral muscles that helium-hyperoxia will improve their exercise endurance.
The purpose of this study is to develop and evaluate the usefulness of MRI using 129Xe gas for regional assessment of pulmonary function. Specifically, three forms of 129Xe MRI contrast will be the investigators focus - 1) imaging of the 129Xe ventilation distribution, 2) imaging the alveolar microstructure via the 129Xe apparent diffusion coefficient (ADC), and 3) imaging 129Xe that dissolves in the pulmonary blood and tissues upon inhalation. Such imaging of 129Xe gas transfer is expected to be uniquely sensitive to pathologies affecting gas exchange (fibrosis, emphysema, pulmonary hypertension) and provide new insights regarding the normal resting heterogeneity of pulmonary gas exchange.
The purpose of this study is to characterize the clinical, physiologic, and molecular profiles of healthy participants, participants with mild, moderate, and severe asthma; and participants with moderate to severe Chronic Obstructive Pulmonary Disease (COPD).
Patients with chronic obstructive pulmonary disease (COPD) are at greater risk of suffering from diseases for which beta-blockers may be indicated and effective. Clinicians remain hesitant to administer beta-blockers to COPD patients for fear of adverse effects on lung function. However, cardioselective beta-blockers therapy led to a non-significant worsening of resting expiratory flow limitation measured by the forced expiratory volume in one second (FEV1) as compared to placebo. But, the FEV1 appears to be a crude estimate bronchial obstruction in COPD. Importantly, the effects of cardioselective beta-blockers on dynamic hyperinflation, a subtle marker of bronchial obstruction, remain unknown. Thus, a prospective placebo-controlled study assessing the effects of short-term cardioselective beta-blocker therapy on dynamic hyperinflation in patients with moderate-to-severe COPD is needed.
In this 5-months study, the response of patients to salbutamol at baseline will be compared with their response to treatment with indacaterol.
The primary objective of this study is to identify biomarkers that can be used for evaluation of efficacy in subjects presenting with AECOPD
This study will invite two groups of volunteers to participate. The data from one group of volunteers will be used to find out how much study drug, known as GSK1325756, is in the blood after taking the drug twice in one day. Data will also collected to find out if the level of cetain blood cells, known as neutrophils, change significantly after taking the study drug twice in one day. This group of volunteers will be aged 40 to 64 years of age. The data from the other group of volunteers will be used to find out if taking the study drug, GSK1325756, twice in one day with or without food, makes a difference to the level of study drug in the blood. This group of volunteers will also provide data to find out if any study drug metabolites are present in the bile, a fluid secreted by the liver. This group of volunteers will be aged 65 to 80 years of age.
