Active clinical trials for "Lung Diseases, Obstructive"

The purpose of this study is to show the efficacy and safety of formoterol for the maintenance treatment of patients with COPD compared with placebo in patients in Japan and in European countries during 12 weeks.

The purpose of this study is to see if treatment with AZD4818 for four weeks is tolerable, safe and effective in treating COPD and, if so, how it compares with placebo.

The purpose of this study is to evaluate the safety and effectiveness of infliximab (Remicade) in patients with Chronic Obstructive Pulmonary Disease (COPD).

The purpose of this study is to evaluate the safety and effectiveness of yoga in reducing shortness of breath in people with chronic obstructive pulmonary disease (COPD). Patients in this study must have moderate to severe COPD and be primarily limited by shortness of breath.

The purpose of this study is to determine if sildenafil improves the exercise capacity and lung function of patients with chronic obstructive pulmonary disease.

The purpose of this trial is to study the effects of roflumilast on lung function parameters indicative of hyperinflation in patients with COPD.

The purpose of this study is to determine the safety and tolerability of single doses of QAB149 up to 3000 µg delivered via a single-dose, dry powder inhaler in patients with mild to moderate COPD.

The objective of this study is to determine if tiotropium (Spiriva, Bromuro de Tiotropio) 18 mcg once daily by oral inhalation compared to placebo increases the magnitude of daily physical activity observed in COPD patients, measured using an accelerometer.

This study evaluates the effect of two medicines on COPD (Chronic Obstructive Pulmonary Disease) exacerbations. This study will last up to 56 weeks, and subjects will visit the clinic 10 times. Subjects will be given breathing tests and will record their breathing symptoms daily on diary cards. All study related medicines and medical examinations will be provided at no cost. The two drugs used in this study have been approved by the FDA for use in patients with COPD.

The investigators' aim is to study the effect of cycling off criteria during pressure support ventilation in COPD patients at two levels of PEEP and PSV.
