Filter by:The purpose of this study is to investigate the effects of the practice of singing for a long period of time on pulmonary function data, quality of life, and dyspnea sensation of patients with COPD in stable clinical conditions. As singing is a type of respiratory training, the study hypothesis is that singing would improve maximal respiratory pressures, dyspnea sensation, and overall quality of life of these patients.
GSK233705 is being developed for the treatment of chronic obstructive pulmonary disease. This will be an open-label, dose-ascending study in 7 healthy male subjects to establish well tolerated intravenous doses and an oral dose of GSK233705. The main objective of the study is to confirm an IV and oral dose for a definitive human radiolabel metabolic study.
This study evaluated the effect of inhaled aclidinium bromide on exercise endurance and in reducing resting and dynamic lung hyperinflation in patients with moderate to severe COPD. It was 9 weeks in duration, consisting of; a 2-week run-in period, 6 weeks of double-blind treatment, and a 1-week follow-up phone call. All patients meeting the eligibility criteria were randomized to one of two treatment groups: aclidinium bromide or placebo.
The purpose of this study is to investigate the effect of combined treatment with Symbicort and Spiriva, in terms of improvement of lung function, symptoms and inflammatory markers, in patients with severe COPD.
The purpose of this study is to determine the effectiveness of antibiotic therapy for patients with acute exacerbations of mild-to-moderate chronic obstructive pulmonary disease.
Sildenafil is a phosphodiesterase-5 inhibitor that has been approved for the treatment of pulmonary arterial hypertension with orphan drug designation. Sildenafil modulates the nitric oxide (NO) pathway in the vessel wall. Since this pathway is impaired in pulmonary arteries of patients with pulmonary hypertension (PH) associated with chronic obstructive pulmonary disease (COPD), we hypothesized that sildenafil might improve pulmonary hemodynamics and increase exercise tolerance in this condition. However, in COPD sildenafil may also impair gas exchange due to the inhibition of pulmonary hypoxic vasoconstriction. The research project is aimed to evaluate these effects. It is a prospective, randomized, double-blind study to evaluate the acute effects of a single dose of 20 or 40 mg of sildenafil on gas exchange and pulmonary hemodynamics. Subjects: 20 patients (10 in each group). Measurements: pulmonary hemodynamics, arterial blood gasses and ventilation-perfusion distributions; at rest and during sub-maximal exercise.
The purpose of this study is to investigate the effect on exercise tolerance, lung function and symptoms after treatment with Symbicort, Oxis or placebo in patients with severe chronic obstructive pulmonary disease.
A study to test the effect of MK0359 in lessening the symptoms of COPD as compared to salmeterol and placebo.
GSK961081 has previously been administered to healthy subjects in a nebulised formulation and the first part of this study which will be conducted in healthy subjects proposes to bridge the change from nebulised to DPI formulation of GSK961081 before administration to patients. The second part of the study will be conducted in COPD patients and aims to assess the safety and bronchodilator profile of GSK961081 over 24 hours, during 14 days dosing.
The role of HGF and KGF in COPD is poorly known. Plantier et al found that cultured fibroblasts harvested from patients with emphysema produced less HGF (but similar amounts of KGF) than controls, and Bonay et al found a direct relationship between the severity of airflow obstruction and HGF mRNA content in lung samples of smokers. These two studies suggest, therefore, that the pulmonary regulation of HGF may be abnormal in patients with COPD. However, both HGF and KGF can also be released by extra-pulmonary organs, thus having the potential to act systemically. Given the current clinical relevance attributed to the systemic effects of COPD, in this study we compared the levels of HGF and KGF in the pulmonary (bronchoalveolar lavage (BAL) fluid) and systemic compartment (circulating blood) of smokers with and without COPD and never smokers.
