Active clinical trials for "Lung Diseases, Obstructive"

A first sub-analysis of the BACE trial will address physical activity levels in a subgroup of the intervention study with portable validated activity monitors.

The study is a randomized, double-blind, placebo-controlled, multiple-dose, pilot study of orally-administered ivacaftor in subjects with chronic obstructive pulmonary disease. Subjects will be administered the study drug ivacaftor 150 mg (or placebo) twice daily (BID).

This study evaluated the safety and efficacy of once and twice daily TD-4208 and placebo when administered using a jet nebulizer for 7 days in a cross-over design to patients with moderate to severe chronic obstructive pulmonary disease.

This study assessed the effect of QVA149 on patient-reported dyspnea in moderate to severe Chronic Obstructive Pulmonary Disease (COPD) patients.

The purpose of this study is to evaluate the safety of Targeted Lung Denervation Therapy (or TLD TherapyTM) in patients suffering from COPD. Technical feasibility of the IPS SystemTM will also be evaluated through confirmation of successful application of TLD Therapy.

This is a comparative bioavailability study to compare the pharmacokinetics and pharmacodynamic effects of Fluticasone propionate and Salmeterol delivered in a capsule-based inhaler versus a multi-dose dry powder inhaler in patients with moderate asthma and in patients with moderate to severe Chronic obstructive pulmonary disease (COPD). Co-primary endpoints will be the area under the curve (AUCτ) measured for plasma Fluticasone propionate (pharmacokinetic) and the pharmacodynamic effects of Fluticasone propionate (weighted mean serum cortisol over 0-12h) on the last day of each 10 day study treatment period. Secondary endpoints will include the following pharmacokinetic parameters for both fluticasone propionate and salmeterol: AUClast, AUC(0-t), Cmax, Cmin, tmax, λz, and t1/2 as well as the pharmacodynamic effects of salmeterol (pulse rate, blood pressure, electrocardiogram [ECG], potassium and glucose) and Fluticasone propionate (urine cortisol levels). Safety (adverse events and laboratory abnormalities) will also be assessed as a secondary endpoint. The study is a randomised, double blind, double dummy, four-period cross-over study. Approximately 60 asthma or COPD patients will be randomised. Patients meeting eligibility criteria will receive Fluticasone propionate/salmeterol 250/50mcg bid, from a capsule-based inhaler and from a multi-dose dry powder inhaler for a period of 10 days each in a randomised order. All patients will receive treatment from each device twice. To maintain the double blind, each patient will receive active treatment and placebo at the same time from two separate devices.

The purpose of the study is to propose that roflumilast is associated with meaningful reductions in biomarkers of pulmonary inflammation and sputum neutrophilia, including confirmation of previously described results, and correlate these findings with improvement in pulmonary function, sputum scores, and quality of life in stable moderate to severe COPD. The investigators aim to demonstrate this regardless of concomitant medication use, including inhaled corticosteroids. Additionally, the investigators hope to provide a mechanistic pathway by which these effects occur.

Exercise intolerance is a major complain of patients with chronic obstructive pulmonary disease (COPD). Dynamic hyperinflation has been recognized as an important limiting factor responsible for the appearance of intolerable dyspnea during exercise. Regular treatment with long-acting bronchodilators promotes a more sustained reduction of hyperinflation and consequent symptom relief and increase in the patient's ability to overcome physical demands of daily life. Tiotropium bromide (TIO) is a new generation, long-acting anticholinergic bronchodilator that significantly improves lung function, reduces symptoms and improves exercise tolerance in patients with advanced COPD. Indacaterol is a new ultra-long duration (>24 h) β2-agonist, which promotes sustained dilation of the bronchi with a once-daily administration. Compared to tiotropium, indacaterol provides evidence that is as effective as tiotropium for bronchodilation, as well as other clinical outcomes such as dyspnea and state of health. However, comparative effects of indacaterol versus tiotropium with regard to outcomes in tolerance, dyspnea and dynamic lung hyperinflation during exercise is scarce. We hypothesized that indacaterol and TIO are not different in terms of exercise tolerance and its determinants (dynamic hyperinflation and dyspnea).

This project proposes to test the hypothesis that osteopathic manipulative treatment (OMT) given to patients with moderate to severe chronic obstructive pulmonary disease (COPD) enrolled in a 12-week pulmonary rehabilitation program (PRP) will result in improved respiratory pump function over and above that seen in sham and control groups. Specifically, we will study the effects of three OMT techniques: (a) thoracic inlet indirect myofascial release; (b) rib raising with continued stretch of the paraspinal muscle to the L2 level; and (c) cervical paraspinal muscle stretch with suboccipital muscle release. The key clinical readouts will include: spirometry, P100 (and index of diaphragm and inspiratory muscle efficiency), maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), as well as laser evaluation of chest wall excursion. Supplementing these objective parameters will be several more subjective clinical outcome measures: exercise tolerance (6-minute walk test), dyspnea (shortness of breath questionnaire), and quality of life questionnaire. Finally, an attempt will be made to correlate biochemical alterations that may shed light on the biological mechanism underlying the OMT procedures.
