Filter by:The purpose of this study is to compare the efficacy and safety/tolerability of indacaterol and glycopyrronium (QVA149) (fixed-dose combination) with fluticasone/salmeterol over a 26-week period in patients with moderate to severe COPD.
A single dose study with the inhaled anti-inflammatory agent PF-03715455 to establish if it has anti-inflammatory activity following a challenge with LPS. Inhaled LPS invokes an acute inflammatory response in the lung which can be seen in induced sputum. PH-0797804 is an internal control for the study.
The aim of this trial is to determine the efficacy, safety and tolerability of 500 µg Roflumilast tablets once daily in patients with COPD in China, Hong Kong, and Singapore.
This study was designed to test the following hypothesis: A) The acute and long-term (3 weeks) bronchodilator-induced changes in exercise tolerance and in the physiological response during the endurance shuttle walk will be greater with tiotropium compared to placebo in COPD patients. B) Three weeks of bronchodilation will be associated with increase activity of daily living as evaluated using the London Chest Activity Daily Living scale.
Chronic Obstructive Pulmonary Disease has two heterogeneous conditions (chronic bronchitis and pulmonary emphysema phenotypes) with a different clinical presentation. The phenotype evaluation in COPD patient (trough clinical, functional and radiographic parameters) could influence final results in pharmacologic and non-pharmacologic management of the disease. The aim of our study is to investigate whether COPD patients with different disease phenotype (chronic bronchitis versus pulmonary emphysema) have a different response to PR.
Oxygen desaturation (SO2 < 88-90%) during walking is a common clinical feature of Chronic Obstructive Pulmonary Disease (COPD) patients. By a predicted analysis our study is aimed to evaluate anthropometric and functional characteristics of COPD patients correlated with oxygen desaturation during Six-minute walking test (6MWT).
This study is evaluating the effectiveness of a dose counter for an inhaler device used to deliver medication to people diagnosed with asthma or COPD.
Chronic Obstructive Pulmonary Disease (COPD) leads to a reduction in exercise capacity that affects the quality of life and increases mortality of these patients. So, exercise tests are considered as an essential component of the clinical evaluation of the patients with COPD. The objective of this study is to evaluate the reproducibility sensitivity and validity of the Six Minute Step Test (6MST) in patients with COPD and in health volunteers, and verify its relation with the "Body-Mass Index, Airways Obstruction, Dyspnea and Exercise Capacity" Index (BODE). This Observational, Transversal, Prospective study will be conducted in the "Special Unit of Respiratory Physiotherapy", of the "Federal University of São Carlos". To participate in this study, 120 subjects, both gender, will be invited and will be allocated in five groups: Group I (30 healthy young subjects of 17 to 27 years old), Group II (30 healthy elderly individuals of 60 to 75 years old), and patients COPD, 60 to 80 years old, with mild, moderate, severe and very severe obstruction determined by the forced expiratory volume in one second (FEV1) by forced vital capacity (FVC) relation "FEV1/FVC" <70% and FEV1 in predict percentage < 80% composing the Group III (20 COPD patients in GOLD stage I), Group IV (20 COPD patients in GOLD stage II) and Group V (20 patients COPD stages III and IV). All subjects will be submitted to body composition and anthropometric assessment, pulmonary function test, three 6-minutes walk test (6MWT) and three 6MST. Furthermore, the patients of the groups III, IV and V will answer the Modified Medical Research Council (mMRC) scale, and BODE index will be calculated to each of them.
This study assessed the effect of once-daily indacaterol and glycopyrronium bromide (QVA149) on exercise endurance in patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD).
Maximal consumption of oxygen (VO2max) during exercise is used in patients with chronic obstructive pulmonary disease (COPD) to stratify perioperative risk. However, the impact of supplemental oxygen to prevent hypoxemia during exercise on maximal oxygen consumption and other ventilatory parameters during maximal exercise in the resting normoxic Chronic Obstructive Pulmonary Disease population is poorly defined. The investigators performed a randomized controlled trial in patients with COPD who underwent cardiopulmonary exercise tests on room air and supplemental oxygen. The investigators compared maximal oxygen consumption and other ventilatory parameters in each individual subject under the two conditions.
