Active clinical trials for "Lung Diseases, Obstructive"

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 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.

The purpose of this study is to determine whether roflumilast can improve metabolic profile and reduce visceral adiposity in patients with chronic obstructive pulmonary disease (COPD).

Objective: Determine whether treatment of perceived stress, anxiety, and depression with anti-depressant therapy improves dyspnea scores, 6-minute walk (6MW) distance and quality of life (QoL) in patients with Chronic Obstructive Pulmonary Disease (COPD) and ILD (Interstitial Lung Disease) undergoing pulmonary rehab. The study is a prospective, randomized, double-blinded, placebo-controlled study to assess the effect of an SSRI on 6MW, dyspnea scores, and QoL in COPD and ILD patients undergoing pulmonary rehab. Thirty subjects that carry an ICD-9 code diagnosis of COPD and/or ILD and CES-D (Center for Epidemiologic Studies Depression) score of > 16 will be recruited from Duke Pulmonary Rehab. Multivariable regression models will be constructed to evaluate the relationship between perceived stress, anxiety, and depression with adjustments by race, gender, age, BMI and GOLD score. A multivariable regression model will be constructed to assess whether treatment of perceived stress, depression, and anxiety with antidepressant therapy (sertraline) is an effect modifier on 6MW distance and dyspnea scores in patients with COPD or ILD who are enrolled in pulmonary rehab. Descriptive statistics will be used to examine the socio-demographic characteristic data. Student t-tests will be performed to assess group differences in continuous data. Categorical variables will be examined using the Pearson's Chi-Squared test.

CHF6297 is a potent and selective inhibitor of human MAP kinase p38 being developed as an anti-inflammatory agent for the treatment of inflammatory airways diseases. The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single and repeat doses of CHF6297 as dry powder formulation in healthy subjects and in COPD patients. This study is the first administration in humans. The study will comprise four parts: Part 1 will consist of two cohorts of healthy male subjects to assess the safety, tolerability and pharmacokinetics of Single Ascending Dose (SAD) of CHF6297. Part 2 will consist of four cohorts of healthy male subjects to assess the safety, tolerability and pharmacokinetics of Multiple Ascending Dose (MAD) of CHF6297. Part 3 will consist of one cohort of COPD patients to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of a repeat dose of CHF6297 Part 4 will consist of one cohort of healthy subjects to assess the anti-inflammatory effect of a repeat dose of CHF6297 after LPS challenge.

This study will test whether daily use of azithromycin will reduce the rate of exacerbations and improve lung ventilation and perfusion assessed by XE-MRI. The sensitivity of XE-MRI to detect COPD progression will be compared with standard clinical assessment measures including standard lung function tests, 6 minute walk test, and patient reported quality of life.

The purpose of the present study is to demonstrate the higher efficacy of small particles Foster® 100/6 (two puffs b.i.d.) versus large particles Symbicort® 200/6 (two inhalations b.i.d.), in terms of residual volume reduction over a 12-week treatment period in Chronic Obstructive Pulmonary Disease (COPD) patients.

The aim of this study is to compare two methods of delivery of noninvasive mechanical ventilation (NIV). Since patient compliance and mechanical characteristics of the delivery devices are two fundamental variables in the success of NIV during acute respiratory failure, our hypothesis is that an improved patient-ventilator interface may improve the efficacy of therapy.

The purpose of this study is to evaluate the safety, effectiveness, and side effects of the CryoSpray AblationTM System (CryoSpray AblationTM, "CSA" or "cryospray therapy") to treat benign airway disease in the lung using liquid nitrogen sprayed through a catheter via flexible fiber optic bronchoscopy (FFB)
