Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

The aim of this family practice based study is to determine the long-term treatment effects of two drugs that are presumed to modify the course and progression of chronic obstructive pulmonary disease (COPD), oral N-acetylcysteine and inhaled corticosteroids.

To evaluate the efficacy and safety of arformoterol tartrate inhalation solution 30μg/4mL QD (two 15μg/2mL dosed in combination) over a 24-hour period compared to arformoterol tartrate inhalation solution 15μg/2 mL BID in subjects with COPD.

The purpose of this study is to compare Symbicort in a pressurized metered-dose inhaler (pMDI) with formoterol and placebo in the long-term maintenance treatment of patients with chronic obstructive pulmonary disease (COPD).

In people with mild COPD, the ability to exhale air from the lungs is partly limited because of narrowing and collapse of the airways. This results in the trapping of air within the lungs and over-distention of the lungs and chest (lung hyperinflation). Breathing at high lung volumes (hyperinflation) is an important cause of breathing discomfort (dyspnea) in people with COPD. Bronchodilators help to relax muscles in the airways or breathing tubes. Bronchodilators are often prescribed if a cough occurs with airway narrowing as this medication can reduce coughing, wheezing and shortness of breath. Bronchodilators can be taken orally, through injection or through inhalation and begin to act almost immediately but with the effect only lasting 4-6 hours. The main purpose of this study is to examine the effects of inhaled bronchodilators on breathing discomfort and exercise endurance in patients with mild COPD.

This will be an open label study conducted at one site. Six healthy male subjects will be enrolled to ensure at least four fully evaluable subjects. Each subject will receive a single 10 milligram (mg) oral dose of GW856553 containing 50 microCi (µCi) of [14C] GW856553. Urine and fecal samples will be collected until 216 hour after dosing but subjects may be discharged after 168 hour if 90% of the dose is recovered and/or <1% of the dose is excreted in a 24 hour period. Blood and plasma will be collected at various sample times after dosing to measure parent drug and total drug-related material. Samples of urine, faeces and plasma will be transferred into a separate study to characterize and quantify metabolites in these matrices. Safety will be assessed by adverse event monitoring, vital signs, electrocardiogram (ECG) and clinical laboratory tests.

The primary objective of this study is to determine the optimum dose(s) of BI 1744 CL inhalation solution delivered by the Respimat® inhaler for four weeks in patients with chronic obstructive pulmonary disease (COPD). The selection of the optimum dose(s) will be based on bronchodilator efficacy (how well it helps your breathing), safety evaluations and pharmacokinetic evaluations (the amount of the medication found in your blood).

The investigators hypothesize that continuation of non-invasive ventilation (NIV) at home after an episode of acute hypercapnic respiratory failure (AHRF) treated by NIV in COPD patients would reduce the likelihood of death and recurrent AHRF requiring NIV or intubation. The investigators designed this study in a way that recruited COPD patients would be started on home NIV or sham treatment after an episode of AHRF requiring acute NIV. The patients are acclimatised to NIV application after a few days of acute use. The investigators chose occurrence of life-threatening event (recurrent AHRF and death) as the primary endpoint.

The primary objective of this study is to compare the bronchodilator efficacy of three doses (50 µg, 100 µg and 200 µg) of BEA 2180 delivered by the Respimat® once daily to placebo and tiotropium bromide delivered by the Respimat® in patients with COPD. Additional objectives include comparing the effects on dyspnea and health status.

GW642444 (the study medicine) is a new experimental medicine for treating asthma and chronic obstructive pulmonary disease (COPD). People with asthma and COPD suffer from breathlessness because the small tubes (bronchioles) that carry air in and out of the lungs become narrow. We hope that the study medicine will work by relaxing the muscles in the airways and help to keep the airways open, and make breathing easier. The study medicine might improve on available treatments by having fewer side-effects, and by working faster and for longer, so that patients could take it once daily, instead of twice daily. When a medicine is made into a form ready to be given to patients, inactive ingredients are often added. Inactive ingredients might be used to help a medicine work better, to make it easier to produce the medicine, or to make it easier to get an accurate dose of medicine. In this study, the study medicine contains the inactive ingredient magnesium stearate. We need to check that the study medicine doesn't cause problems when inhaled along with magnesium stearate. So, we're doing this study in healthy people to find out the answers to these questions. 1)Do repeated once-daily doses of the study medicine cause any important side effects when inhaled, along with magnesium stearate, as a fine powder? 2)How much of the study medicine gets into the bloodstream and how long does the body take to get rid of it?
