Filter by:Spirometry is a useful clinical tool for the assessment and monitoring of lung disease, however, it does not provide information on peripheral airways resistance. On the contrary, impulse oscillometry (IOS) may provide information not only on airway resistance (Rrs) but also on the elastic properties of the lung (Xrs). In addition, multiple breath nitrogen washout (MBNW) utilizes the exhalation of nitrogen gas from the airways to determine changes in lung ventilation and derive small airways indices (that tells us about small airways calibre). This method, like IOS, allows a precise assessment of small airways function. Even though patients with asthma may show some reduction of the caliber of the small airways these changes are more a feature of patients with COPD. The study team hypothesize that IOS and MBNW measurements may detect these differences and provide different resistance profiles for asthma and COPD. Furthermore, the study team would like to investigate the relationship between airway inflammation and small airway disease by measuring exhaled nitric oxide (NO) at multiple exhalation flow rates. This technique allows the partitioning of NO produced in the central airways from that generated more peripherally in the lung, providing valuable information on the activity of inflammation in different parts of the respiratory system. The study team hope that the combined use of IOS, MBNW and NO will identify a possible correlation between inflammation and small airway dysfunction.
The purpose of this study is to evaluate the efficacy and safety of GSK233705B compared with placebo in subjects with COPD.
GSK961081 is a potent dual pharmacophore that demonstrates both antimuscarinic and beta-agonist pharmacology in preclinical studies, both pharmacologies being of long duration. If reproduced in man, GSK961081 has the potential to deliver a medicine that can be given once daily. The bronchodilatation after inhalation of single doses of GSK961081 alone and in the presence of the short acting beta agonist salbutamol and the short acting muscarinic antagonist, ipratropium bromide will be measured in this study. Any residual bronchodilatation post-inhalation of GSK961081 and demonstrated by addition of salbutamol or ipratropium bromide may provide an indirect assessment of the beta-agonist and antimuscarinic components of GSK961081
This purpose of this study is to assess the safety of ramelteon, once daily (QD), in subjects with chronic obstructive pulmonary disease.
GW642444 and GSK233705 are in development for treatment of Chronic Obstructive Pulmonary Disease. Development of these two inhaled drugs as a combination therapy would have potential for improved patient benefit as they both work through different mechanisms and the combined bronchodilatory effect might be additive. This study will look at the this combination, for the first time, in healthy subjects.
This study will assess the safety and efficacy of a range of oglemilast doses. The study will be 14 weeks in duration. All patients meeting the eligibility criteria will be randomized to one of three doses of oglemilast or placebo.
This study will evaluate the onset of action of indacaterol (150 and 300 µg) as compared to placebo, salbutamol 200 µg and salmeterol/fluticasone 50/500 µg
This project aims to explore the relationship between Vitamin D deficiency and COPD progression via a prospective randomized placebo-controlled study. For this purpose, study was powered to 120 patients hospitalized with an exacerbation of COPD randomly assigned to a monthly oral dose of Vitamin D versus placebo. Taking into account dropouts, 182 patients are randomized during the course of the study
To investigate the efficacy and safety of repeated dosing of Levalbuterol over 6 weeks of treatment in COPD.
Primary objective: Evaluation of the safety of Seretide discus administration in subjects with COPD. Treatment duration: 2 years. Study has 3 phases: Screening phase (visit 1), treatment phase (visits 2-5. In the case of AE, there will be another visit (visit 6) as a follow up visit - follow up phase.
