Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Examine the effects of TI in combination with an anti-diabetic regimen including inhaled insulin versus anti-diabetic treatment without inhaled insulin on lung function & pulmonary safety

The purpose of this study is to evaluate effects of inspired gas mixtures on the distance walked by patients with severe Chronic Obstructive Pulmonary Disease (COPD) during a Six-Minute Walk test.

This study evaluates the effect of two medicines on COPD (Chronic Obstructive Pulmonary Disease). The study will last 12 weeks. At the end of 12 weeks of treatment, subjects will stop the study medicines for 2 weeks. The study will involve 6 visits to the clinic. Subjects who elect to undergo bronchoalveolar lavage (BAL) procedures will have 8 study visits. Subjects will give sputum, blood, and in some cases BAL samples. Subjects will have breathing tests and will complete diary cards during the study. All study medicines and examinations will be given at no cost to the study subjects. Both medicines used in this study have been approved by the US FDA.

This is an investigator-sponsored research study to evaluate if treatment with HFA-134a beclomethasone (QVAR) has an effect on peripheral (or outer) airway inflammation and airway "remodeling" or scarring in subjects with COPD. Approximately 20 subjects with COPD will participate for approximately 7 weeks, with 10 receiving an active (BDP) inhaler with HFA-134a and 10 receiving a placebo.

The purpose of the VENT Cost-Effectiveness Sub-Study is to gather healthcare utilization and quality of life information on patients enrolled in the VENT study in order to analyze the relative cost-effectiveness of the endobronchial valve implant procedure.

To evaluate changes in activity based on the use of portable oxygen concentrators combined with standard of care (SOC) long- term oxygen therapy versus SOC long-term oxygen therapy alone at 12 weeks in patients with COPD who require continuous (24/7) long-term oxygen therapy. The study will also assess oxygen usage, quality of life, hospitalizations and death.

Study to compare the lung and oropharyngeal deposition of Berodual® (fenoterol hydrobromide 50μg + ipratropium bromide 20μg /1x puff) delivered via the Respimat® inhaler and the same dose of Berodual® delivered via an hydrofluoroalkane (HFA) - metered dose inhaler (2 x puffs ) in COPD patients at different inspiratory flow rates.

This is a randomized, double-blind, cross-over, vehicle-controlled study to determine whether GS-5737 in 2.8% saline accelerates mucociliary clearance (MCC) in healthy subjects, compared to vehicle of 2.8% saline alone.

The purpose of this research study is to determine whether analysis of genes in sputum is a useful noninvasive technique for measuring response to drugs in patients with COPD. We propose to use polymerase chain reaction to evaluate gene expression in induced sputum from adult current smokers with moderate COPD, adult former smokers with moderate COPD. This study is designed to determine whether changes in expression of previously-identified inflammatory markers in induced sputum can be detected in response to drug therapy in COPD and to evaluate potential differences in the expression of these markers in adult smokers with and without COPD. Pre- and post-treatment serum will be obtained to facilitate proteomic analysis of therapeutic response as well. Changes in sputum gene expression in response to treatment will be the primary outcome variable in this study. Secondary outcomes will include changes in lung function, as well as changes in induced sputum inflammation. These endpoints will be evaluated before and directly after 6 weeks of randomly-assigned treatment with either salmeterol xinafoate or fluticasone propionate/50mcg salmeterol xinafoate combination DPI bid. Endpoints will be re-evaluated following a 4 week wash-out period.

The primary objective of this study is to look for a correlation between the use of high-flow nasal cannula in the outpatient setting in patients with previous chronic obstructive pulmonary disease exacerbation and the change in their Breathlessness, Cough, and Sputum Scale score. The hypothesis is that home use of high-flow nasal cannula will lead to a reduction in Breathlessness, Cough, and Sputum Scale score by 1.3.
