Filter by:Objectives (include all primary and secondary objectives) Specific Aim #1: To determine whether an air cleaner intervention to improve home air quality will improve respiratory symptoms, quality of life, lung function and reduce risk of exacerbations in former smokers with COPD. Hypothesis: An intervention using high-efficiency particulate air (HEPA) and carbon filter air cleaners in homes of former smokers with COPD will improve respiratory symptoms, quality of life, and lung function and reduce risk of COPD exacerbations compared with placebo (sham air cleaners). Specific Aim #2: To determine whether an air cleaner intervention to improve home air quality will be associated with intermediate outcome measures known to be linked with long term outcomes in COPD, including airway and systemic markers of inflammation and oxidative stress, in former smokers with COPD. Hypothesis 2: An intervention using HEPA and carbon filter air cleaners in homes of formers smokers with COPD will be associated with lower levels of markers of inflammation and oxidative stress known to be associated with adverse outcomes in patients with COPD.
Study to obtain further information on the tolerability and efficacy of Atrovent® unit dose vial 500 µg in the treatment of Chronic Obstructive Airways Disease under conditions of daily practice
This is a 12-week, multicentre, randomized, open-label, 2-arm, parallel-group study designed to compare the efficacy and safety of umeclidinium inhalation powder (62.5 mcg once daily [QD]) administered via a novel Dry Powder Inhaler (nDPI) with glycopyrronium (44 mcg QD) administered via a Breezhaler® inhaler in subjects with COPD over 12 weeks of treatment. At the end of the run-in period, eligible subjects will be randomized in a 1:1 ratio to receive umeclidinium 62.5 mcg administered via nDPI or glycopyrronium 44 mcg administered via BREEZHALER inhaler. There will be up to 8 clinic visits conducted on an outpatient basis at Pre-Screening (Visit 0), Screening (Visit 1), Randomization at Day 1 (Visit 2), and after Randomization at Day 2 (Visit 3), Day 28 (Visit 4), Day 56 (Visit 5), Day 84 (Visit 6) and Day 85 (Visit 7). The total duration of subject participation in the study will be approximately 15 weeks. The primary endpoint of the study is clinic visit trough FEV1 (forced expiratory volume in one second) on treatment Day 85. All subjects will have spirometry performed at clinic Visits 1 though 7. Trough spirometry will be obtained 23 and 24 hours after the previous day's dose of open-label study medication at Visits 3 to 7. BREEZHALER is a registered trademark of Novartis AG.
Study to assess the safety of two-week administration of 80 and 160 mcg of ipratropium bromide as delivered by the RESPIMAT® device and as determined by 24 hours ambulatory ECG monitoring in COPD patients. To assess the overall safety of the two doses of ipratropium bromide as delivered by the RESPIMAT® device when administered over a two-week period.
The objective of this study was to determine the pharmacokinetic comparability of 84 µg ipratropium bromide HFA-134a inhalation aerosol and 84 µg ATROVENT® CFC Inhalation Aerosol in COPD patients
The current definition of chronic obstructive pulmonary disease (COPD) is based on the presence of persistent airflow obstruction assessed by spirometry. About half of the subjects with mild COPD (i.e. reduced forced expiratory volume in one second (FEV1) on forced vital capacity (FVC) ratio along with normal FEV1] are asymptomatic. Subjects with symptomatic mild COPD have reduced exercise tolerance and abnormal dynamic ventilatory mechanics compared to healthy subjects. The physiological and perceptual responses to exercise of subjects with asymptomatic mild COPD are currently unknown. The purpose of this study is to assess exercise tolerance, ventilatory constraints on tidal volume expansion and dyspnoea in asymptomatic mild COPD subjects undergoing incremental cycle cardiopulmonary exercise testing (CPET) to the limit of tolerance compared with symptomatic mild COPD and healthy controls.
This study examined whether health coaches can improve the management of chronic obstructive pulmonary disease (COPD) in a population of vulnerable patients cared for in 'safety-net' clinics. The study is designed as a randomized controlled trial for patients with moderate to severe COPD. Patients were randomized into a health coaching group and a usual care group. Those in the health coaching group received 9 months of active health coaching. Outcome variables were measured at baseline and after 9 months
