Not only do these individuals suffer from lung disease, but COPD often leads to other illnesses, particularly heart disease. Beta-blockers very successfully treat heart disease. It is therefore logical that one would want to use this treatment in COPD patients with heart disease too. However, there has always been concern that beta-blockers could cause significant problems in COPD by worsening lung function, as these can have the opposite effect to inhalers used to treat COPD that open up airways. Pointedly, there is increasing evidence that despite this problem, COPD patients who have been prescribed beta-blockers have been shown to gain benefit particularly in terms of preventing death. In this study, the investigators therefore want to examine which beta-blocker might be the safest for COPD patients, as each work slightly differently. Some beta-blockers may have a more beneficial effect on airways than others, whilst still benefitting the heart. The investigators will study two different beta-blockers; one that potentially narrows airways and one that potentially opens airways. The investigators will be using cardiopulmonary exercise testing (an exercise bike that measures both heart and lung function during exercise) to look for differences between both beta-blockers primarily in terms of lung function but also with information about the heart. The investigators will recruit people with moderate to severe COPD who are able to complete a cycle exercise test through their respiratory research department. The study will last for 10-12 weeks with 5 main visits to the department for serial exercise tests, breathing tests, simple heart function tests and simple blood tests that will tell the investigators what other effects these beta-blockers are having on the heart and lungs.
The investigators are looking at whether a new type of nebuliser (a machine used to deliver drugs to the airways) is better at delivering drugs to the lungs of people with Chronic Obstructive Pulmonary Disease (COPD), compared with the current nebulisers used in Emergency Departments. The investigators will randomly allocate patients who come into the Emergency Department with an acute episode of the COPD into either the standard nebuliser group or the new nebuliser group. Both groups will receive the same medications, it is only the method of delivering them which will be different.
This study is a post-authorization commitment to the European Medicines Agency (EMA). The study serves to determine whether the treatment of patients with stable, symptomatic Chronic Obstructive Pulmonary Disease (COPD) with the investigational drug NVA237 is efficient and safe. The efficacy and safety of the drug was tested for twice daily dosing against once daily dosing.
This study will evaluate the effects of Chen-style Tai Chi compared to conventional exercise in pulmonary rehabilitation for COPD patients. Half of participants will receive the Chen-style Tai Chi intervention, while the other half will receive the conventional exercise intervention. Both groups will receive the same eduction and support during pulmonary rehabilitation.
The purpose of this trial is to determine whether a minimal homebased psychoeducative intervention is effective in management of anxiety and dyspnea in patients with severe chronic obstructive pulmonary disease.
1: Is endothelium function impaired in COPD? Other chronic cardiovascular diseases are associated with endothelial dysfunction, and the endothelium plays an important role in regulating vascular tone, tissue blood flow, coagulation and the inflammation process. Although the specific causes of endothelial dysfunction remain unclear, physical inactivity, chronic systemic inflammation and smoking are all known to be associated with endothelial abnormality. 2. Is Muscular Sympathetic Nerve Activity (MSNA) increased in COPD? A balanced regulation of blood flow to skeletal muscles may be disturbed by pathophysiology and may therefore contribute to the exercise intolerance and skeletal muscle depletion seen in patients with COPD.Skeletal muscle blood flow is tightly regulated to match tissue oxygen demands and is thus adapted to meet energy requirements. During physical activity, the sympathetic nervous system is activated ("exercise pressor reflex"), resulting in increased ventilation, heart rate and a redistribution of cardiac output from inactive to active tissues. The redistribution of cardiac output to the body organs is heterogeneous. Blood flow to skeletal, respiratory and cardiac muscle increases as exercise intensity increases, whereas blood flow to gastrointestinal, renal and reproductive tissues decreases. As blood pressure during exercise remains largely unchanged, the redistribution of blood flow is caused by changes in vascular conductance. These conductance changes are caused by an overall vasoconstriction induced by the increased sympathetic outflow of noradrenaline (NA), and a vasodilation of vascular beds supplying the working skeletal -, cardiac- and respiratory muscle.
This is a trial of 12 weeks of treatment with nebulized SUN-101 using an Investigational eFlow® Closed System (CS) nebulizer in subjects with chronic obstructive pulmonary disease (COPD) according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD 2014) guidelines.
Patients with Chronic Obstructive Pulmonary Disease are characterised by a sedentary lifestyle. This contributes to increase the number of hospitalizations and mortality. Changing this lifestyle is a major objective of the management of these patients. Pulmonary rehabilitation helps patients to increase their fitness, but modifying a longstanding sedentary habit is more difficult to achieve. This project aims at modifying patients' long term physical activity with a physical activity coaching programme. This will help patients to transform the benefits of pulmonary rehabilitation into a healthier active lifestyle and contribute to reduce hospitalizations, increase quality of life and survival.
This is a phase IIIa, randomised, double-blind, double-dummy, parallel group multicenter study evaluating once daily FF/UMEC/VI (100 microgram [mcg]/62.5 mcg/25 mcg) inhalation powder versus twice daily budesonide/formoterol (400 mcg/12 mcg). The primary purpose of this study is to demonstrate improvements in lung function and health status for subjects treated with FF/UMEC/VI compared with budesonide/formoterol for 24 weeks. Once-daily 'closed' triple therapy of a Inhaled Corticosteroid/ Long-acting Muscarinic Receptor Antagonists/ Long Acting Beta-Agonist (ICS/LAMA/LABA) combination FF/UMEC/VI (100 mcg/62.5 mcg/25 mcg) in a single device is being developed with the aim of providing a new treatment option for the management of advanced (GOLD Group D) COPD which will reduce the exacerbation frequency, allow for a reduced burden of polypharmacy, convenience, and increase the potential for improvement in lung function, Health Related Quality of Life (HRQoL) and symptom control over established dual/monotherapies. Subjects meeting all inclusion/exclusion criteria and who have successfully completed all protocol procedures at the Screening Visit will enter the two-week run-in period. Following the run-in period, eligible subjects will be randomised (1:1) to one of the following double-blind treatment groups: FF/UMEC/VI 100 mcg/62.5 mcg/25 mcg via the ELLIPTA™ dry powder inhaler (DPI) once daily in the morning and placebo via reservoir inhaler twice daily OR Budesonide/formoterol 400 mcg/12 mcg via reservoir inhaler twice daily and placebo via the ELLIPTA DPI once daily in the morning. The target enrollment is 1800 randomised subjects at approximately 200 study centers globally. The total duration of subject participation will be approximately 27 weeks, consisting of a 2-week run-in period, 24-week treatment period and a 1-week follow-up period. Subjects will run-in on their existing COPD medications for 2 weeks and in addition will be provided with short acting albuterol/salbutamol to be used on an as-needed basis (rescue medication) throughout the study. Subjects will discontinue all existing COPD medications during the randomised treatment period but may continue their study supplied rescue albuterol/salbutamol. A sub-set of approximately 400 subjects will remain on blinded study treatment for up to a total of 52 weeks to provide additional long term safety data.
