Filter by:The purpose of this study is to provide pivotal efficacy and safety data for QVA149 in patients with moderate to severe COPD.
This study will investigate if adding a domiciliary respiratory physiotherapy treatment to standard care in patients with chronic obstructive pulmonary disease (COPD) can improve physical function (walking test) and quality of life.
The investigators hypothesise that phosphodiesterase 5A inhibitors will improve exercise capacity in those with Chronic Obstructive Pulmonary Disease and secondary pulmonary hypertension.
There are three elements to this study: - Part A: Single dose escalation in healthy subjects. 6 dose levels of QAK423 are planned in healthy volunteers. - Part B: Single dose escalation in patients with mild/moderate COPD. 3 dose levels of QAK423 are planned in COPD patients. - Part C: Titrated repeat dosing for a maximum of 14 days in mild/moderate COPD patients. Repeat dosing is planned in COPD patients.
Chronic obstructive pulmonary disease (COPD) is a frequent airway disease characterized by both bronchial inflammation and remodelling. Bronchial mucosa is infiltrated by macrophages, neutrophils and lymphocytes. In addition, the number of eosinophils can be also increased during exacerbation. Airway remodelling is an abnormal tissue repair following bronchial inflammation, which contributes to none reversible pathological features, such as bronchial and peri-bronchial fibrosis. It also influences the prognosis of COPD and its mechanisms remain largely unknown. The role of fibrocytes has been demonstrated in the pathophysiology of asthma, lung fibrosis or pulmonary hypertension. However, the recruitment of blood fibrocytes and their involvement in COPD airway remodelling remain unknown.
The aim of this clinical trial is to evaluate the effect of chronic obstructive pulmonary disease (COPD) and/or obstructive sleep apnea syndrome (OSAS) on the endothelial function, before cardiovascular surgery, compared to non COPD non OSAS patients undergoing also a cardiovascular surgery, by an observational physiological study. An interim analysis will be performed when 100 patients will be included.
The main objective is to evaluate the bronchodilatory efficacy, safety and pharmacokinetic profiles of A006 (Albuterol Dry Powder Inhaler (DPI)), in comparison with those of an active control, Proventil-HFA (Albuterol Metered Dose Inhaler (MDI)), and a Placebo DPI in escalating and cumulative-doses up to 1440 mcg, eight (8) times of the proposed clinical dose.
This is a 26 week randomized controlled study. The study consists of, in order, an enrollment visit, followed by clinic visits at 2 weeks, 14 weeks and at 26 weeks. There will also be telephonic assessments at 8 weeks and 20 weeks. Clinic visits will involve comprehensive assessments of the patients lung condition, including post-bronchodilator spirometry, Shuttle walk distance, BODE index, health status (SGRQ) and symptoms (CCQ). Sputum and serum samples will also be collected at these visits for microbiological and inflammation analysis. Sputum will be obtained with the Lung Flute as an induction device and Pulse Oximetry will be assessed prior to and after use of the Lung Flute. Clinic and telephonic visits will collect information regarding compliance with the use of the Lung Flute, adverse events and exacerbation history.
National Institute for Clinical Excellence (NICE) guidelines recommend high dose inhaled steroids for patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD, a common chronic disease related to smoking) who are having two or more exacerbations requiring treatment with antibiotics or oral steroids in a 12 month period. The preparations licensed for this indication commercially available are Symbicort® and Seretide®. High dose inhaled steroids (contained in both) can cause suppression of the adrenal glands. The investigators want to assess adrenal suppression caused by the two preparations and compare. The results could guide investigators in prescribing these preparations.
The purpose of this study is to compare the efficacy of oxygen therapy delivered by systems using oxygen-saving valves or not (continuous oxygen). We aim to determine if systems using oxygen-saving valves are equally effective as continuous oxygen delivery systems in reducing exercise-induced hypoxemia in patients with COPD.
