Filter by:The compound GW642444 has previously been found to be well tolerated with no significant side effects in subjects with asthma and healthy volunteers. This study will assess the safety and tolerability of GW642444 in subjects with COPD in order to obtain information to support dosing in a broader population of subjects with COPD
To evaluate the efficacy and safety of LAS 34273 compared to placebo in patients with moderate to severe COPD during one year of treatment.
This is a comparator study to assess the relative efficacy of the combination product fluticasone propionate/salmeterol 50/500 and tiotropium bromide on the rate of exacerbations of chronic obstructive pulmonary disease (COPD) over a two year study interval.
To evaluate the efficacy and safety of LAS 34273 compared to placebo in patients with moderate to severe COPD during one year of treatment.
This study will last for approximately 14 weeks and will involve 5 visits. The study is being carried out to look at different ways of measuring the effect of drug treatment on COPD. COPD is a respiratory disease which can affect your breathing and daily life. Symptoms of COPD can include breathlessness, cough, and wheeze. COPD varies enormously from patient to patient. The effects of drug treatment are usually measured by conducting lung function tests (breathing tests) using a machine called a spirometer but this does not always provide a complete picture of how well your COPD is responding. In this study we therefore want to look at new and more sensitive ways of measuring COPD. The results of this research will help in the assessment of new drugs for COPD in the future.
To evaluate and compare two methods of weaning from mechanical ventilation in patients with chronic obstructive pulmonary disease (COPD) where the extubation failed.
This study will last up to 3 years. You will visit the clinic up to 14 times. Certain visits will include lung function tests and scans of your bones. The purpose of this study is to determine the effect of the steroid component of an inhaled product on bone mineral density in patients with Chronic Obstructive Pulmonary Disease (COPD).
Hypothesis: The reduction of dynamic hyperinflation and its negative effects on the respiratory system following a bronchodilator could lead to an improvement of cardiac function in terms of increased cardiac output. This may enhance oxygen delivery to the exercising muscles in COPD patients. Bronchodilator administration may also have an indirect effect on V'O2 kinetics via its action on cardiovascular and pulmonary variables. Objectives: 1. To evaluate the effects of a bronchodilators on V'E , V'CO2 , and V'O2 kinetics in COPD during constant work-rate cycle exercise, and to evaluate whether bronchodilators will accelerate, indirectly, phase 2 kinetics (usually slower in COPD patients than normal subjects) and shorten t for V'E, V'CO2 , and V'O2 and shorten half-times for HR and O2 pulse, thus showing an improvement of oxygen transport to the peripheral active muscles. 2. To determine the impact of a bronchodilator-induced reduction in dynamic hyperinflation, and its effects on cardiovascular and pulmonary function, on exercise limitation in COPD.
This study is being conducted to see if PRX-08066 can lower pulmonary artery pressures in patients with pulmonary hypertension associated with chronic obstructive pulmonary disease.
This clinical study is designed to explore dose ranging and identify methods to demonstrate the efficacy of Erdosteine in patients with stable Chronic Bronchitis associated with Chronic Obstructive Pulmonary Disease.
