Filter by:This study group forms the normal subject control group in an experiment designed to determine whether the alveolar macrophages (AMø) of patients with chronic obstructive pulmonary disease (COPD) show abnormal responsiveness to bacterial and viral products. Specifically, the study will determine the dose-response characteristics of AMø for production of interleukin (IL)-6, IL-18, and IL-23 (pro-inflammatory cytokines) on stimulation by purified lipopolysaccharide, a synthetic lipopeptide (PAM3-Cys), or poly I:C. These stimuli mimic the response to Gram-negative bacteria, Gram-positive bacteria, and RNA viruses, respectively. Results of the AMø from these healthy volunteers will be compared with AMø of COPD patients and smokers (or ex-smokers) with normal pulmonary function; those samples are being obtained during clinically indicated bronchoscopies under a separate consent form.
The purpose of this study is to determine whether the alveolar macrophages (AMø) of patients with chronic obstructive pulmonary disease (COPD ) show abnormal responsiveness to bacterial and viral products, relative to smokers with normal pulmonary function. Participation in this study will be offered to patients already scheduled to undergo a bronchoscopy for clinical indications.
GSK233705 is a high-affinity specific muscarinic receptor (mAChR) antagonist which is being developed for once daily treatment of chronic obstructive pulmonary disease (COPD). The long duration of action of GSK233705 when administered via inhalation in animal models supports the potential for use as a once-daily bronchodilator for chronic obstructive pulmonary disease.

The objective of this trial is to evaluate whether the effect of one year (48 weeks) treatment with inhaled tiotropium bromide (Spiriva® - 18 µg once daily) on the change in trough FEV1, compared to placebo in patients with COPD, is affected by smoking status.
The primary objective of this study is to investigate the effect of tiotropium vs. placebo on trough FEV1 and FEV1 2 hours post inhalation after 12 weeks of treatment. For both endpoints changes from baseline will be analysed. Three strata of patients will be included (severe COPD, i.e. <35% of predicted FEV1, moderate COPD, i.e. 35% - <50% of predicted FEV1, mild COPD, i.e. 50% - 70% of predicted FEV1, according to American Thoracic Society [ATS] criteria). The study is conducted in order to find out for which endpoint tiotropium is different from placebo in which stratum.
The primary objective of this trial is to determine whether treatment with tiotropium (18 mcg) capsule once daily via the HandiHaler reduces the proportion of patients with COPD experiencing an exacerbation and the proportion of patients hospitalized for an exacerbation during a six month observation period.
To evaluate changes in PaO2 following inhalation of Tiotropium by HandiHaler compared to Salmeterol MDI in patients with moderate to severe COPD.
The study was designed to determine whether tiotropium inhalation capsules, compared to placebo, enhances the improvement in exercise tolerance seen in patients with chronic obstructive pulmonary disease (COPD) who participate in pulmonary rehabilitation. In addition, assessments of the effect of tiotropium on dyspnea and quality of life following pulmonary rehabilitation were taken.
The objective of this study is to compare the bronchodilator efficacy and safety of tiotropium inhalation capsules (18 mcg once daily) and Atrovent MDI (2 puffs of 20 mcg q.i.d.) in patients with chronic obstructive pulmonary disease (COPD)
The objective of the study is to determine the effect on lung function when either SPIRIVA once daily or placebo once daily is added to the usual therapy (care) of COPD patients naïve to anticholinergic agents managed in primary care. Previous studies have been in both hospital in and outpatients, with washout of some respiratory medications, this is the first study to be conducted in General Practice, the drug's anticipated environment. Data from this study, including the adverse event monitoring, and post study findings on physical examination, will be used to extend the safety database. Health Resource Utilisation (HRU) data will be recorded to be use with data from other sources for economic analysis of COPD treatment.
