Although drug therapies and pulmonary rehabilitation have greatly improved COPD symptoms, as many as 50% of patients with severe COPD have inadequately controlled dyspnea. Device-guided breathing is a behavioral intervention that guides respiratory rates into a therapeutic range; prolongation of the expiratory phase improves hyperinflation, the most significant driver of dyspnea in this population. Device-guided breathing, has no known side-effects, and may represent a cost effective adjunctive treatment for dyspnea in severe COPD.
This is a 52-week treatment, multi-center, randomized, open label, parallel group study to assess the long term safety and tolerability of once-daily QVA149 (indacaterol and NVA237 ([glycopyrronium bromide]) using tiotropium as an active control in Japanese patients with moderate to severe chronic obstructive pulmonary disease (COPD).
Chronic obstructive pulmonary disease (COPD) is a progressive and largely irreversible lung disease characterized by chronic bronchitis and/or emphysema, resulting in breathlessness, cough and sputum. As COPD progresses, patients experience increasing deterioration of their health-related quality of life, with greater impairment in their ability to work and declining participation in social and physical activities. The aim of this non-interventional study is to evaluate data on quality of life in COPD patients in Germany in a real life medical setting under therapy with the phosphodiesterase-inhibitor (PDE-4) roflumilast (Daxas). Evaluation is based on two COPD specific questionnaires to assess the patient`s health status over six months. During the study, lung function measurements such as spirometry will be conducted according to common medical standard. Daxas (tablet) will be administered once daily. The study will provide further data on the safety and tolerability of Daxas.
AZD2115 Single Ascending Dose Study
Patients with chronic obstructive pulmonary disease (COPD) are at greater risk of suffering from diseases for which beta-blockers may be indicated and effective. Clinicians remain hesitant to administer beta-blockers to COPD patients for fear of adverse effects on lung function. However, cardioselective beta-blockers therapy led to a non-significant worsening of resting expiratory flow limitation measured by the forced expiratory volume in one second (FEV1) as compared to placebo. But, the FEV1 appears to be a crude estimate bronchial obstruction in COPD. Importantly, the effects of cardioselective beta-blockers on dynamic hyperinflation, a subtle marker of bronchial obstruction, remain unknown. Thus, a prospective placebo-controlled study assessing the effects of short-term cardioselective beta-blocker therapy on dynamic hyperinflation in patients with moderate-to-severe COPD is needed.
DHEA prevents and reverses chronic hypoxic pulmonary hypertension in a chronic hypoxic-pulmonary hypertension model in the rat. However, no study has been performed in human. The purpose of this study is to determine if DHEA is effective in the treatment of respiratory pulmonary hypertension in adults with Chronic Obstructive Pulmonary Disease (COPD) on exercise capacity and haemodynamic variables. Patients will receive after randomisation either 25 mg/day or 200mg/day oral DHEA over a one-year period. Evaluation concerns clinical parameters, echocardiography and right catheterization after and before treatment. Primary end-point is the six-minute walk test. This is a prospective double blind, randomised, placebo controlled study which will be realized in four university hospitals in France : Bordeaux, Strasbourg, Toulouse and Limoges.
In this 5-months study, the response of patients to salbutamol at baseline will be compared with their response to treatment with indacaterol.
The cardiovascular component associated with COPD plays a major role in prognosis of the disease, being responsible of 25% of the deaths. Experimental and initial clinical data suggest that beta-adrenergic agonists accelerate clearance of excess fluid from the alveolar airspace, with potential positive effect on cardiogenic pulmonary edema. The aim of this study was to investigate the effects of a long-acting beta-2 agonist, salmeterol, on alveolar fluid clearance in COPD patients by evaluating the diffusive and mechanical lung properties. Our experimental model to test alveolar fluid clearance was rapid saline intravenous infusion. Ten COPD and 10 healthy subjects treated with salmeterol or placebo 4 hours before the begin of the study were evaluated, in four non consecutive days, just before and after a saline infusion or a similar period without infusion. Both in COPD and healthy subjects rapid saline infusion, with placebo or salmeterol premedication, lead to a significant decrease of DLCO and FEV1. Nonetheless, salmeterol pretreatment lead to a significant reduction of the impairment of gas exchange due to saline infusion (-64% of DLCO reduction in comparison with placebo), whilst it did not affect the changes in FEV1. In the control setting, with no infusion, we did not find any significant change of both DLCO and mechanical properties of the lung. In conclusions, in COPD patients salmeterol appears to provide a protective effect against an acute alveolar fluid clereance challenge secondary to lung fluid overload providing an intriguing mechanistic explanation for the benefits observed in larger trials.
Hypothesis: Can a counseling intervention, delivered by a pharmacist, increase inhaler adherence in veterans with COPD who have demonstrated poor inhaler adherence through pharmacy refill records? Veterans who receive who receive daily maintenance inhalers from the William S Middleton Memorial Veterans Hospital Pharmacy and who have a medication possession ratio less than 80% over the previous six months will be invited to participate in the study. This study will randomize 100 participants to a usual care arm or a pharmacist counseling intervention. Final data collection will be six months after randomization to determine if both self-reported and refill record adherence has changed.
