Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

This study in Chronic Obstructive Pulmonary Disease (COPD) patients will investigate the bronchodilatory effect of AZD8683. AZD8683 will be tested versus placebo and an active comparator.

This project (funded by the IWT-TBM program) will organize a randomized placebo-controlled multicenter intervention trial in 500 COPD patients to study the effectiveness and safety of azithromycin therapy in the acute setting of COPD exacerbations requiring hospital admission. Although long-term use of azithromycin is proven effective to prevent exacerbations, inherent risks outweigh the benefits. By reducing the dose and duration of the azithromycin treatment and by restricting the treatment to acute periods with highest risk for treatment failure, benefits may counterbalance potential side effects, which may result in a new treatment strategy for these acute events. The present study is designed by the services of respiratory medicine of the Leuven and Ghent University hospitals but will run in total in 17 different large hospitals in Belgium, of which 12 are located in Flanders.

The investigators' hypothesis is that pretreating patients with COPD with inhaled treprostinil prior to pulmonary rehabilitation sessions will result in improved exercise tolerance during sessions. This in turn will lead to an increased response to pulmonary rehabilitation, resulting in improved exercise tolerance and quality of life.

The purpose of this study is to determine the effect of preventing hyperglycaemia in patients admitted to hospital with acute exacerbations of chronic pulmonary disease.

Study compares the efficacy and safety of tiotropium + a beta agonist (procaterol) vs. tiotropium alone among patients with moderate chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is a long-term lung disease that is caused by cigarette smoking or by breathing in other lung irritants, including pollution, dust, or chemicals. The purpose of this study is to evaluate the effectiveness of zileuton, a medication that is used to control asthma symptoms, at reducing the length of a hospital stay for adults who are hospitalized for a COPD exacerbation, or worsening of COPD symptoms.

Non-invasive ventilation is frequently applied in patients with acute exacerbation of COPD, but no evidence exists about the effect of long term application/home application. This study tests the hypothesis, that a daily, 6 hour application of non-invasive ventilation over one year improves survival, exercise capacity, and quality of life in patients with advanced stages of COPD.

This is a study to evaluate the effectiveness and tolerability of a once-daily oral medication (MK-0873) for the treatment of COPD (chronic obstructive pulmonary disease) to determine whether the study drug leads to an improvement in pulmonary (lung) function, as well as symptoms, and quality of life.

This is a randomized, open-label, parallel group, multicenter, outpatient study in COPD subjects who are discharged from the hospital due to a COPD exacerbation. Subjects who meet the eligibility criteria will be randomized to 1 of 2 treatments: arformoterol tartrate inhalation solution (BROVANA) 15 mcg twice daily (BID) or tiotropium bromide (SPIRIVA) 18 mcg once daily (QD), each given for 90 days.

The purpose of this study is to investigate how budesonide/formoterol fumarate dihydrate (Symbicort ©) affects dynamic hyperinflation in patients with obstructive disease using Optoelectronic Plethysmography (OEP). This study is unique as it will be the first randomized, doubleblind, crossover study with a placebo inhaler and budesonide/formoterol fumarate dihydrate as the intervention which will evaluate the effects on ventilatory mechanics through the use of OEP. The investigators plan to demonstrate that budesonide/formoterol fumarate dihydrate impacts dynamic hyperinflation which can be detected with OEP, and that budesonide/formoterol fumarate dihydrate may have an effect in the short term on exercise capacity during a constant load exercise test. The changes in ventilatory mechanics measured after budesonide/formoterol fumarate dihydrate by OEP will provide a unique evaluation of budesonide/formoterol fumarate dihydrate in a controlled setting also demonstrating the utility of OEP in evaluating of the effects of a medical treatment on hyperinflation in individuals with chronic obstructive lung disease (COPD). Primary Objective/Hypothesis: Our objective is to measure baseline, post treatment and post exercise spirometry and evaluate exercise dynamic hyperinflation before and after treatment using OEP. The investigators hypothesize that budesonide/formoterol fumarate dihydrate will decrease dynamic hyperinflation as measured by OEP. Primary Endpoint: Our primary endpoint is the change in dynamic hyperinflation, specifically end expiratory volumes, dynamic lung volumes and diaphragmatic paradoxical breathing as measured by OEP. Secondary Objective: Our secondary objective is to evaluate duration of steady state exercise and exercise capacity before and after treatment. Our secondary hypothesis is that decreases in dynamic hyperinflation during exercise will lead to improvements in dyspnea with exercise, and allow for increases in exercise capacity. Secondary endpoint: Exercise time, change in Borg scale at rest vs. Borg scale at steady state vs. Borg at end exercise.
