Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

The investigators believe that iloprost will improve gas exchange in COPD patients with pulmonary hypertension.

Chronic obstructive bronchitis and emphysema (COPD) are pathophysiologically characterized by inflammatory and structural changes in the lung. These changes lead to a reduction in elastic recoil as well as reduction in lung parenchyma. As a consequence collapse of the small airway occurs during expiration leading to expiratory flow limitation. In severe cases this flow limitation occurs even during resting condition. This expiratory collapse is suspected to mask changes in bronchial smooth muscle tone, especially if these changes in bronchial smooth muscle tone are assessed using expiratory manoeuvres. This might leave the impression of non-reversible airway obstruction und ineffectiveness of treatment with bronchodilators. Several studies suggest that in patients with COPD symptomatic changes following application of a bronchodilating compound do not correlate with changes in forced expiratory volumes. In contrast inspiratory lung function parameters (especially forced inspiratory volume in one second (FIV1)) is much more associated with symptomatic changes in patients with COPD. Comparable effects were also detected regarding peak inspiratory flow (PIF) values.Changes in inspiratory parameters following administration of a bronchodilator in patients with COPD and asthma are reproducible. PIF can easily be measured by inspiratory peak flow meters. So far no data exists on the usability of these devices following bronchodilation in patients with COPD. Formoterol is a rapid acting bronchodilator, which has been proven save in asthma and COPD

This is a randomised, double-blind, double-dummy, multinational, multicentre, parallel group trial comparing tiotropium (18 mcg) inhalation capsule via HandiHaler and salmeterol (50 mcg) via MDI in patients with COPD. There will be a two-week run-in period followed by a 52-week randomised treatment phase. Patients who withdraw prematurely from trial medication will be encouraged to remain in the trial and participate in follow-up telephone contacts until their predicted normal exit date from the trial (i.e. 52 weeks after taking the first dose of randomised treatment). The phone calls will be made at all scheduled visits. The primary objective of this study is to compare the effect of tiotropium (18 mcg) inhalation capsule via HandiHaler with that of salmeterol (50 mcg) via MDI on COPD exacerbations. The primary endpoint is time to first COPD exacerbation during the 52 week randomised treatment period. A COPD exacerbation will be defined as a complex of respiratory events / symptoms (increase or new onset) of more than one of the following: cough, sputum, wheezing, dyspnoea or chest tightness with at least one symptom lasting at least three days requiring treatment with antibiotics and/or systemic steroids and/or hospitalisation. The onset of an exacerbation is defined as the onset of the first new or increased reported symptom. The end of the exacerbation should be recorded as defined by the investigator. Only COPD exacerbations with onset during randomised treatment will be included in the analysis.

This study evaluated the safety and efficacy of 26 weeks treatment with indacaterol, placebo or salmeterol in patients with chronic obstructive pulmonary disease.

PH-797804 is a potent ant-inflammatory drug that may reduce the inflammation that is associated with COPD. PH-797804 will be dosed to patients with COPD to evaluate its potential safety and efficacy profile in COPD.

This study is being done to examine the influence of Tiotropium (good or bad) on heart function at rest and during exercise in patients with moderate to severe chronic obstructive pulmonary disease (COPD).

This study will evaluate the safety and tolerability of the cfor the first time in mild to moderate COPD patients.

A study to evaluate the effect of SB-656933-AAA on the body after a single dose in subjects who have been challenged with ozone.

Relatively little information is available about the effects of salmeterol/fluticasone combination and fluticasone alone in COPD patients with a partial reversible pulmonary obstruction. The purpose of this study is to compare the effects of salmeterol/fluticasone combination with fluticasone alone delivered via Diskus/ACCUHALER inhaler in subjects with COPD on lung function over a 1 year period.

This is a study to investigate the reliability, ruggedness and safety of the top mounted actuation indicator (TMAI) when used with Levalbuterol HFA MDI.
