Filter by:The aim of this study was to assess the effectiveness for small airway inflammation of 4 weeks lysozyme administration in Chronic Obstructive Pulmonary Disease (COPD) and/or asthma.
Pulmonary rehabilitation has been established as an evidence-based and recommended therapy in patients with chronic obstructive pulmonary disease (COPD). The aim of our study is to show a potential change in muscle fibre composition and in the amount of capillaries in quadriceps muscle from pre tob post 3-week rehabilitation. Pulmonary rehabilitation includes standardised exercise training, e.g. cycling and strength training for major muscle groups.
This study will compare the efficacy of indacaterol versus placebo (i.e., rescue medication only) and tiotropium in patients with Chronic Obstructive Pulmonary Disease (COPD) who have not received maintenance COPD medication for at least 12 months prior to entry (described hereafter as "maintenance naïve", see inclusion criteria).
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 will be tested against a placebo treatment. The primary criterion to assess efficacy will be the difference between the serial lung function measurements of patients who have been treated for 12 weeks with NVA237 versus those that have received placebo treatment for 12 weeks. A serial lung function measurement (FEV1 testing) will be conducted and the "area under the curve" will be the measure for the ability to breathe.
The aim of this study was to evaluate kallikreins and its substrate, CCN, in COPD patients. Kallikreins are a subgroup of serine proteases, enzymes which are able to cleave peptide bonds in proteins. Kallicrein profile is unkonwn in COPD. The investigators will assess Kallikrein 1 to 15 and CCN 1 to 6 in sputum of patients. Three groups of patients will be included: Healthy smoker subjects, stable COPD patients and COPD patients with acute exacerbation. Kallicrein levels in sputum will be compared in these groups.
The purpose of the investigation is to confirm the safety and efficacy in long-term use of Symbicort Turbuhaler in patients with Chronic obstructive pulmonary disease (COPD) under the post-marketing actual use.
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). 1. 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. 2. 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. 3. 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. 4. Secondary endpoint: Exercise time, change in Borg scale at rest vs. Borg scale at steady state vs. Borg at end exercise.
This study will assess the efficacy, safety and tolerability of indacaterol maleate/glycopyrronium bromide in patients with moderate to severe airflow limitation.
To demonstrate the non-inferiority of QVA149 110/50 µg o.d. to fluticasone/salmeterol 500/50 µg b.i.d. in terms of trough Forced Expiratory Volume in one second (FEV1) (mean of 23 hours 15 min and 23 hours 45 min post QVA149 dose) following 26 weeks of treatment in patients with moderate to severe COPD
