Active clinical trials for "Lung Diseases, Obstructive"

The objective of this study is to test the efficacy of a Mindfulness Based Stress Reduction program in COPD on quality of life, dyspnea, daily physical activity and mindfulness during daily life.

The purpose of this study is to demonstrate the clinical equivalence of formoterol-HFA pMDI 12µg/actuation administered twice daily to formoterol DPI 12µg/capsule delivered by the Aerolizer inhaler and administered twice daily in patients with COPD.

The purpose of this study is to assess the effect of treatment with Advair Diskus on depression using the Cornell depression scale in COPD patients in the nursing home.

The purpose of the study is to evaluate the safety of administering repeated doses of CTX-100 (formerly ETX-100) to subjects with smoking-related chronic obstructive pulmonary disease.

This study is designed to investigate the effect of home mechanical ventilation (HMV) in patients with severe chronic obstructive pulmonary disease (COPD). The purpose of the trial is to test the hypothesis that HMV and longterm oxygen therapy (LTOT) increases admission free survival compared with LTOT alone. More specifically, compared with LTOT, HMV and LTOT reduces hospital re-admission in COPD patients who remain persistently hypercapnic following an acute exacerbation requiring non-invasive ventilation (NIV).

The purpose of this study is to evaluate, after 1 week of dosing, the efficacy and safety of PT003 compared with its individual components (PT001 and PT005), placebo and two active comparators to demonstrate superiority of the combination to its components, and to assess the relative contribution of the components compared with placebo, in patients with moderate to very severe COPD.

The objective of this study is to demonstrate that, when added to tiotropium (TIO), fluticasone propionate/salmeterol combination (FSC) DISKUS 250/50 significantly increases exercise endurance time (EET) in the endurance shuttle walk test (ESWT), compared to TIO alone. Male and female subjects at least 40 years of age with a diagnosis of Chronic Obstructive Pulmonary Disease (COPD) are eligible. Subjects will be screened and consented at or during a 6-week (wk) period prior to visit (V)1. The 4-wk run-in period begins immediately after V1, when subjects receive open-label TIO plus as-needed relief inhaler (identical formulations called albuterol in the US and salbutamol in Canada). At V2, subjects will perform an incremental shuttle walk test (ISWT) to establish their maximal walk response. The first ESWT will occur at V3. Subjects must demonstrate an EET of ≤20 min that is reproducible (EET from V3 and V4 varying by ≤2 min). Eligible subjects are then randomized at V5 to either FSC 250/50mcg DISKUS twice daily plus open label TIO 18 mcg daily, or placebo DISKUS twice daily plus open label TIO 18 mcg daily for the 4-wk treatment period. The last study visit is V6. The primary efficacy measure is the difference between the EET at V6 (wk-8) vs. V4 (wk-3; the last ESWT done before randomized study drug is given). Secondary efficacy measures include V6 vs. V4 comparisons in exercise dyspnea scale (EDS), exercise inspiratory capacity (EIC) and cardio-respiratory measurements (CRM), and V6 vs. V5 comparisons in dyspnea related to activities of daily living (baseline dyspnea index and transition dyspnea index interviewer-administered [BDI-TDI]) and quality of life (Chronic Respiratory Disease Questionnaire Self-administered Standardized [CRQ-SAS]). The safety measure will be an assessment of adverse events. We will also attempt to validate prospectively the minimal clinically-important difference (MCID) for a change in the EET through correlation with dyspnea and quality of life results.

The purpose of this study is to assess the safety and efficacy of a single dosage strength of GW685698/GW642444 in subjects with Chronic Obstructive Pulmonary Disease (COPD).

Chronic obstructive pulmonary disease (COPD) is characterized by increased oxidative stress which aggravates airway and systemic inflammation. Previous studies suggested that dietary factors such as ample consumption of antioxidants might have beneficial effects in lung function in COPD patients. The investigators' primary aim is therefore to investigate prospectively whether a nutritional intervention consisted of diet rich in antioxidants such as fresh fruits and vegetables, would significantly affect lung function decline in COPD patients compared to a free diet. Methods: This is a 3-year prospective study, incorporating a run-in period of six months and outpatient clinic visits, scheduled every 6 months. Consecutive sampling was used to recruit 120 patients with COPD. At baseline and at each visit all patients were evaluated for respiratory symptoms, dietary habits, medication used and pulmonary function. Patients will be randomized either to a diet based on increased consumption of foods containing antioxidants (fresh fruits and vegetables), intervention group (IG) or, to a free diet, control group (CG). The investigators hypothesize that the results from the study will suggest that a diet rich in antioxidants may be associated with improvement in lung function in COPD patients. In this respect dietary interventions should be considered in the management of COPD.

Patients with Chronic obstructive pulmonary disease (COPD) tend to have cough, excess mucus production and breathlessness as cardinal features. The excess mucus production often leads to frequent infections, exacerbations and poor quality of life. Mucociliary clearance may have an impact on improving symptoms, exercise tolerance, quality of life and reduce exacerbations. High frequency chest wall oscillation(HFCWO) devices use percussion to the chest wall delivered from a pump through a close fitting inflatable vest. This technique has been shown to enhance mucus clearance in patients with cystic fibrosis and Bronchiectasis. This pilot study was designed to explore the feasibility, tolerance and effectiveness of the HFCWO in patients with advanced COPD.
