Active clinical trials for "Lung Diseases"

GSK233705 is a high-affinity specific muscarinic receptor (mAChR) antagonist which is being developed for the treatment of chronic obstructive pulmonary disease. This is a randomised, double-blind, placebo-controlled, dose ascending, parallel group study to examine the safety, tolerability, pharmacokinetics and pharmacodynamics of twice daily inhaled doses of GSK233705B for 7 days, in COPD subjects.

The purpose of this study is to determine whether water based or land based group training is more effective for people with COPD.

Bronchopulmonary dysplasia (BPD) is a serious lung condition that affects premature newborns. The condition involves abnormal development of lung tissue and is characterized by inflammation and scarring in the lungs. Treatment with inhaled nitric oxide (iNO) may reduce the incidence of BPD and another commonly associated condition called pulmonary hypertension, which is high blood pressure in the vessels carrying blood to the lungs.. This study will determine if early treatment with low-dose iNO reduces the incidence of BPD, pulmonary hypertension, and death in premature newborns.

Some patients with chronic obstructive pulmonary disease (COPD) take nebulised treatments to ease the symptom of breathlessness, including the drug ipratropium. Nebulised bronchodilator drugs are taken up to 4 times through the day, and this can take up to 15 minutes each time. Although the treatment isbe effective, patients report that the time taken to set-up and use the nebuliser can be a disincentive to regular use. By contrast, an inhaler device is easy to use following appropriate instruction, and takes only a few seconds to administer. Inhaled tiotropium is a once daily treatment taken by inhaler which has been shown to be effective in COPD. We wish to assess whether inhaled Tiotropium as effective as nebulised ipratropium in patients with stable chronic obstructive pulmonary disease.

Cystic fibrosis (CF) is a chronic disease that significantly affects an individual's lung function. Antibiotic medications have been proven effective at reducing Pseudomonas aeruginosa (PA) infection, which is one of the main causes of death in individuals with CF. The purpose of this study is to compare the effectiveness of treatment based on quarterly culture results versus consistent quarterly antibiotic treatment at reducing PA infection in children with CF.

The purpose of this study is to determine whether the Aridol (mannitol) challenge test can predict response to treatment with inhaled corticosteroids in COPD subjects. Subjects will undergo an Aridol test and then 3 months of treatment with inhaled corticosteroids. The effect on lung function and quality of life will then be measured and correlated with the Aridol test result.

The study has two objectives/aims: Aim 1: To test the efficacy of the intervention among adult smokers with cardiovascular disease, pulmonary disease and diabetes mellitus related illnesses (later modified to Chinese adults with and without diseases); and Aim 2: To examine a set of measures (background, general health, psychosocial, and smoking process) that are associated with smoking cessation at 6 and 12 months

This study (A7881006) is the first multiple dose study in moderate asthmatic subjects and aims to determine the safety and efficacy of PF-00610355 when subjects take PF-00610355 on a daily basis for 4 weeks in subjects maintained on inhaled corticosteroid.

Patients with Chronic Obstructive Pulmonary Disease (COPD) suffer from frequent and recurrent acute exacerbations (AECB) which are associated with enormous healthcare expenditures and significant morbidity, specifically an increased risk of death, a decline in pulmonary function and a significant change in quality of life. Bacteria appear to have an important role in acute exacerbations in chronic bronchitis and COPD. Studies of acute exacerbations in COPD have shown a reduction in bacterial load with prolonged exacerbation-free interval. In addition, recent studies indicate that acquisition of a new strain of H. influenzae, M. catarrhalis, S. pneumoniae or P. aeruginosa are responsible for many of these exacerbations. Chronic inflammation and bacterial infection predispose many patients to frequent and recurrent acute exacerbations. Mpex, (the sponsor on record at time of the study's initial registration) believes that intermittent administration of inhaled MP-376 in high risk patients will decrease the incidence of acute exacerbations by both by lowering the organism burden, and resultant inflammation, as well as pre-emptive eradication of any newly acquired bacterial strains.

This is a clinical research study to assess whether after exhaling a single cigarette smoke through the nose there are changes in the inflammatory cells and proteins of nasal secretions. A single blood sample from each subject will be stimulated with cigarette smoke in the laboratory to see the effects on inflammatory blood cells. Comparison of findings between smokers with COPD and "Healthy" smokers will be carried out. We hypothesize that some subjects have amplified inflammatory response to a single cigarette, and these will be those subjects who develop chronic obstructive pulmonary disease (COPD) after decades of smoking. We hope to develop an acute challenge model that relates to the causation of COPD. When studying the effects of new drugs, these may be detected in small numbers of patients in a challenge situation, when we would need to study many more unchallenged patients to demonstrate drug effects. In clinical research on asthma and allergy, the nasal allergen challenge has been a very successful model, and we hope to validate a comparable model for COPD.
