Active clinical trials for "Lung Diseases"

This is a study to evaluate the effectiveness and tolerability of a once-daily oral medication (MK-0873) for the treatment of COPD (chronic obstructive pulmonary disease) to determine whether the study drug leads to an improvement in pulmonary (lung) function, as well as symptoms, and quality of life.

The purpose of this study is to quantify the dose of aerosol medication deposited in the lungs of lung transplant recipients receiving a single nebulized treatment of aerosolized Abelcet® (lipid complexed amphotericin-B). This study is being performed to determine the range of deposited doses and patterns of distribution that could be expected in this population so that the ultimate efficacy of this preparation can be evaluated. A radioisotope technique will be utilized to track the medication dose. The study will include 12 subjects who will perform one testing session lasting approximately 3 hours. An Investigational New Drug Application (IND) detailing this protocol has been submitted by the principal investigator (PI) and approved by the Food and Drug Administration [FDA] (72,521).

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 determine whether roflumilast can improve metabolic profile and reduce visceral adiposity in patients with chronic obstructive pulmonary disease (COPD).

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 primary objective of this study is to evaluate the safety, tolerability, and efficacy of pomalidomide in the treatment of patients with systemic sclerosis with interstitial lung disease.

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.

The aim of the study is to examine the validity of peripheral oxygen saturation measurement during the 6-minute walk test in patients with Systemic Sclerosis (SSc) and to examine the utility of two other functional tests as markers of pulmonary involvement in patients with SSc.

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 aim of this study is to assess the impact of endocrine changes and their correction on survival and organ function in heart and lung transplant recipients. This study also features an investigation of the hormone levels and hormonal replacement therapy of the donors to study its role in the function of the transplanted hearts and lungs. Thyroid hormones (TSH, thyroxine, tri-iodothyronine), cortisol and the antidiuretic hormone will be studied. The former two hormone levels will be defined in the recipients just before transplantation and three days later. In the case of the donors all three hormones will be recorded at the time of the explantation. The investigators would like to record the hormonal replacement therapy in all our patients as well to see it's effect on survival and on the transplanted organ function. After the transplantation during the hospital stays all the important hemodynamic parameters, laboratory parameters, the result of the medical imagings, the medication, the length of ICU and hospital stay and the complications were recorded. Recipients will be followed for five years. Organ function will be assessed every three month for a year, after than every six month for further four years. Investigator would like to record the result of the cardiac echocardiography, spirometries, imaging, and complications. Our purpose is to compare these results against the endocrine disorders and the replacement therapy.
