NCT01266395
Observational study to know the Impact of morning symptoms in clinical control of COPD patients. 1200 patients will be included by General practitioners (GPs) and pneumologists.

NCT00920127
Obstructive airways disease is a very common condition. This condition includes patients with asthma, chronic obstructive pulmonary disease (COPD), emphysema or chronic bronchitis. Some patients with obstructive airways disease have problems with long term breathlessness, wheeze and cough with or without sputum production. Currently the researchers give treatments - usually inhalers - which are designed to open the airways and reduce the breathlessness and wheeze. Despite these available treatments many patients still have continuing symptoms. Anecdotal clinical evidence suggested that a herbal remedy (called AKL1) has beneficial effects in respiratory conditions, with patients diagnosed as having both asthma and COPD reporting reduced symptoms including breathlessness and cough and reduced frequency of attacks.The purpose of this study is to confirm whether AKL1 does indeed have a meaningful benefit to patients with obstructive airways disease. The researchers will mainly be measuring any effect of AKL by assessing any change in trial subjects' coughs, using a questionnaire, but the researchers will also looking at breathing tests, walking tests, blood and sputum tests.
NCT00939211
Chronic Obstructive Pulmonary Disease (COPD) is a chronic respiratory condition with deteriorating lung function over the years. Patients with COPD experience symptoms of shortness of breath, cough and sputum production. This study is to assess the treatment effects after inhalation of three different single doses of AZD9164 (100, 400 and 1200 mcg) and one single dose of tiotropium (18 mcg). One dose of placebo will be given as comparator. 25 patients are to participate in the study and all will be recruited in Sweden. Each patient will visit the study doctor 9 times during the study, whereof 5 visits will be overnight visits. All examinations, treatment and the follow-up is free of charge.
NCT01402297
The aim of the study is to investigate the effect of inhaled apocynin on ROS (reactive oxygen species) and NOS (reactive nitrogen species) synthesis in 13 COPD patients. Effects of nebulized apocynin (0.5 mg/ml, 6 ml) were assessed in exhaled breath condensate (EBC) after 30, 60 and 120 minutes.
NCT00949195
Background: The extent of increase in systolic pulmonary arterial pressure (PAPs) during exercise in patients with COPD is unpredictable from lung function data. The non-invasive assessment of pulmonary hemodynamics during exercise and flow-mediated vasodilatation measurement may give useful data in the rehabilitation of COPD patients. Methods: Patients with stable, severe COPD and healthy, age-matched subjects (H) perform semi supine echocardiography with PAPs measurement. COPD patients perform ramp protocol with gas exchange detection. Serum hsCRP level is also determined in COPD patients. Endothel dysfunction is detected by flow mediated vasodilation measurement after arm strangulation with Doppler ultrasonography. Primary endpoint: The degree of pulmonary artery systolic pressure change during exercise? Secondary endpoint: 1. The degree of right ventricular function change during exercise? 2. Is endothel dysfunction manifested with pulmonary artery pressure rise? 3. What is the correlation between the systemic inflammatory marker hsCRP and the degree of pulmonary artery pressure rise?
NCT00292838
To investigate the validity of a clinical model to determine the relative potency of different preparations of inhaled corticosteroids used for the treatment of asthma or of eosinophilic bronchitis without asthma.
NCT00981851
The final purpose of this study is to determine whether bronchodilation and cigarette smoking in Chronic Obstructive Pulmonary Disease (COPD) patients interact, resulting in an increase of cardiovascular disease. The aim of this part of the study is to demonstrate the basic mechanism: Does increased respiratory function after administration of a bronchodilator in patients with COPD lead to elevated pulmonary retention of the harmful compounds in inhaled cigarette smoke and to short-term biological effects associated with cardiovascular disease?
NCT01364181
Pulmonary hypertension (PH) is a serious complication of COPD which is associated with shorter survival, more frequent exacerbation, and increased use of health resources. There is no effective pharmacological treatment for COPD-associated PH. Therefore, the investigators wanted to evaluate the effect of udenafil, a phosphodiesterase- 5 (PDE-5) inhibitor, on exercise capacity of severe COPD patients.
NCT00904384
The prevalence of COPD in HIV+ and AIDS patients is unknown. The pathophysiology of HIV infection and COPD might be of interest to both conditions. The research hypotheses of this study are: In patients with HIV infection living in the Autonomous Community of the Balearic Islands (CAIB): 1. The Prevalence of airflow obstruction in patients with HIV infection is higher than in the general population. 2. In these patients, the prevalence of emphysema detected by HRCT is common (greater than or equal to 15%) 3. DLCO measurement is a good marker for the presence of emphysema on CT 4. The inflammatory response is different from that seen in patients with COPD and / or emphysema without HIV infection
NCT01226199
Smoking is the most important risk factor of COPD, but only a fourth of smokers had COPD in their life. There are also healthy smokers without evidence of COPD. Investigators hypothesize that innate immunity may affect this difference between COPD patients and healthy smokers, because TLR4 is the receptor of LPS, which is the one of important substance in cigarette. Investigators will measure TLR2 and TLR4 expression in lung tissue of patients whose lung will be resected. Investigators will compare the level of expression between COPD patients and healthy smokers.
NCT00507949
The purpose of this trial is to study the effect of megestrol acetate in the gain of body weight in patients with severe Chronic obstructive pulmonary disease in order to improve the survival of the patients.
NCT01108913
The purpose of this study is to determine whether inhalation of Bimosiamose is safe and effective in the treatment of patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD)
NCT00568503
This will be a single dose Proof-of-Concept study in mild-to-moderate COPD patients. The study will investigate the safety and tolerability of QAX028 as well as the bronchodilatory effects of QAX028 compared to tiotropium and placebo in mild-to-moderate COPD patients.
NCT01096173
This study is intended to be an evaluation of the properties of human sputum collected from patients with COPD. It is hypothesized that cationic airway lining modulators will have beneficial effects on the rheological properties of sputum derived from patients with COPD. Approximately 10 patients with COPD will collect sputum at home for 5 days. Samples will be collected and tested in laboratory tests.
NCT00893009
Chronic obstructive pulmonary disease (COPD) is a chronic progressive respiratory disorder causing disability with an increasing burden to the patient, his family and to the health services. Treatment of COPD patients depends on the stage of the disease. COPD responds poorly to corticosteroids, in spite of inflammation is a major component in its pathogenesis. A major barrier to therapy of COPD is resistance to the anti-inflammatory effects of corticosteroids. The molecular mechanisms for this corticosteroid resistance are now being elucidated, particularly as the molecular basis for the anti-inflammatory effects of corticosteroids is better understood (12). An important mechanism of corticosteroid resistance in COPD, which is also linked to amplification of the inflammatory process, is a reduction in the critical nuclear enzyme histone deacetylase (HDAC)2 . Since the major changes are at the level of small airways. We will examine the effect of addition of theophylline product to stable COPD patients treated with combined inhaler of inhaled corticosteroids.
NCT01329276
Computational Fluid Dynamics (CFD) is a new functional imaging method. Since CFD is very sensitive to detect small changes, it might be worthwhile to study the acute effect of formoterol and budesonide combination therapy (Symbicort® forte Turbohaler®) on the upper airway dimensions in severe COPD patients (GOLD III). The increased sensitivity of this technique makes it possible to detect changes in airway caliber in early stages. The regional distribution of resistance and the change in this parameter will provide more insight into the mode of action of the product.
