Active clinical trials for "Lung Diseases, Obstructive"

The use of inhaled hypertonic saline has been extensively documented in asthma, bronchiectasis, cystic fibrosis and COPD as method of bronchial challenge and sputum induction, but studies that evaluated others endpoints are required. The objective of this study was to analyse the effects of inhaling hypertonic saline compared with placebo with respect to functional exercise capacity, dyspnoea and quality of life. In a double-blind randomised parallel placebo-controlled trial, conducted at the Clínicas Integradas of the Evangelical Faculty of Paraná,sixty-eight patients (age 67 ± 6.5 years; FEV1 38.9 ± 16.2 predicted) were randomised to inhale 3% hypertonic saline (n=34) or placebo (n=34), combined with a program of exercise, three times a week, for 8-weeks.

This project aims to explore the relationship between Vitamin D deficiency and COPD progression via a prospective randomized placebo-controlled study. For this purpose, study was powered to 120 patients hospitalized with an exacerbation of COPD randomly assigned to a monthly oral dose of Vitamin D versus placebo. Taking into account dropouts, 182 patients are randomized during the course of the study

This study will assess the efficacy and safety of glycopyrronium bromide (NVA237) in patients with stable COPD, in comparison to an active comparator.

This study will evaluate the pharmacokinetics, pharmacodynamics and safety of multiple doses of the NVA237 in mild and moderate COPD patients .

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