Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

This is a phase 2, Multi-center, double-blind, randomized, placebo-controlled study to evaluate the effects of inhaled Iloprost in patients with pulmonary hypertension secondary to COPD. The main objective is to investigate the effect of iloprost on exercise endurance time during constant work rate cardiopulmonary exercise testing. Other efficacy and safety endpoints will additionally be analyzed.

The primary objective of the study is to investigate the effect of the combined therapy 18 μg tiotropium q.d. plus pulmonary rehabilitation versus placebo plus pulmonary rehabilitation on 6-minute walking distance (6MWD) after 7 weeks of treatment in patients with moderate to severe COPD. The secondary objective of the study includes assessments of the effects of the combined therapy 18 μg Tiotropium q.d. plus rehabilitation versus placebo plus rehabilitation on dyspnoea, constant work rate exercise endurance, daily activity and lung volumes. The third objective of the study is to investigate the correlation between the results of the 6-minute walking test (6MWT), the constant work rate exercise test (CWR) and daily activity.

The primary objective of the study is to evaluate the efficacy of Helium/Oxygen (He/O2) 78%/22% compared to a conventional Air/O2 mixture in reducing endotracheal intubation rate and mortality in patients with severe hypercapnic exacerbations of Chronic Obstructive Pulmonary Disease (COPD) during their index Intensive/Intermediate Care Unit (ICU) stay.

The aim of the project is to study pathogenetic mechanisms in severe asthma and compare those mechanisms in chronic obstructive pulmonary disease (COPD) in order to test the hypothesis that severe asthma and COPD develop into similar chronic degenerative changes.

Twenty per cent of the intensive care patients mechanically ventilated suffer from chronic obstructive pulmonary disease (COPD). These patients stay longer in Intensive Care which is more costly and they are more prone to nosocomial infection.In addition, they are longer bedridden and they develop muscular weakness.Prolonged inactivity results in respiratory and skeletal muscle weakness which curtails simple daily activity.The principal purpose of this study is to compare two types of muscular rehabilitation (electrical stimulation of the thigh and/or cycloergometer training) to classic passive mobilization of the leg.The second purpose is to analyse the effects of each type of rehabilitation on muscular fiber (structural and functional analysis) by muscular biopsies.Two hundred forty COPD patients admitted in the intensive care unit for acute respiratory failure will be randomized in 4: 1 fashion to receive passive mobilization of the legs(group 1, n=60), electrical stimulation of the thigh (group 2, n=60), cycloergometer training (group 3, n=60) or electrical stimulation of the thigh and cycloergometer training(group 4, n=60).The rehabilitation program will last 4 weeks with 5 sessions per week.In each group of patients, muscular biopsies will be done under local anaesthesia at the beginning and end of the rehabilitation programme and when they are discharged from the service.

The primary objectives of this study are to assess bronchodilator efficacy as determined by FEV1, the effect on dyspnoea as determined by the BDI/TDI, the effect on health status as determined bt the SGRQ and the effect on COPD exacerbations

The primary objectives of this study are to assess bronchodilator efficacy as determined by forced expiratory volume in one second (FEV1), the effect on dyspnoea as determined by the Baseline Dyspnoea Index/Transition Dyspnoea Index (BDI/TDI), the effect on health status as determined by the St George Respiratory Questionnaire (SGRQ) and the effect on chronic obstructive pulmonary disease (COPD) exacerbations.

Chronic Obstructive Pulmonary Disease (COPD) affects over 14 million people in the United States. It is the fourth leading cause of death and the only leading cause of death for which mortality rates are rising. Medical science has developed few effective therapies for COPD. In patients with advanced COPD and chronic hypoxemia, long-term oxygen therapy (LTOT) has been shown to be uniquely beneficial. It is the only available non-surgical therapy demonstrated to prolong survival in these patients. This study will compare the clinical and physiologic benefits of two different oxygen therapy devices among hypoxemic individuals with COPD: a lightweight ambulatory oxygen device versus the standard portable E-cylinder device.

A One Year Clinical Trial Assessing the Usefulness and Safety of Inhaled Insulin in Diabetics with Chronic Obstructive Pulmonary Disease.

In this proposal, we will implement a randomized controlled trial to determine whether nocturnal NIMV applied for 3 months: 1) improves (disease-specific) health related quality of life (HRQL) of COPD patients compared to a control group of patients treated with sham NIMV therapy (primary outcome); 2) improves exercise tolerance and walking capacity of COPD patients; and 3) improves heart rate variability and decreases sympathetic tone in COPD.
