Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

REVASC is a randomized, double-blind, placebo-controlled study which will involve 150 patients with chronic bronchitis and COPD diagnosed cardiovascular disease. The recruitment period beginimg in the coming weeks, will last nine months. Patients included in the study will receive treatment for three months with roflumilast 500 mg (75 patients) or placebo (75 patients) in a randomized manner. The CIBERES, as promoter of this study is expected to release final results for the third quarter of 2013. Eight centers in Madrid will be involved in this clinical trial: Fundación Jiménez Díaz, Hospital La Princesa, Hospital Gregorio Maranon Hospital Clinico San Carlos, Hospital La Paz, Hospital Ramón y Cajal Hospital Doce de Octubre and Hospital Puerta del Hierro. Roflumilast is a potent phosphodiesterase-4 inhibitor (PDE4). Its clinical efficacy has been studied in an extensive clinical program involving over 12,000 patients with COPD. In these studies, roflumilast (in combination with long-acting bronchodilators) reduced the number of exacerbations and improved lung function, especially in those patients with associated chronic bronchitis.

Present treatment for chronic obstructive pulmonary disease (COPD) has a certain role in reducing COPD exacerbation and hospitalization, improving the life quality, and postponing the lung function decline. But for some patients with severe COPD, current treatment only partially alleviates the symptoms and has little role in the lung function decline. In this randomized, multicenter study, the investigators evaluate the safety and efficacy of bosentan in the treatment of grade Ⅲ or Ⅳ COPD patients with pulmonary hypertension detected by echocardiography. The primary endpoint is the frequency of COPD exacerbation, and the secondary endpoint includes changes of lung function, 6-min-walk distance (6-MWD), SGRQ score and mMRC/CAT score.

Investigators developed a test to assess the bronchodilator effects in mechanically ventilated chronic obstructive pulmonary disease patients by comparing the change of airway resistance. No matter whether patients respond to bronchodilator or not, they are randomized assigned to bronchodilator 3-4 times per day group and no bronchodilator group. Then investigators could objectively decide whether individual patients need or benefit from bronchodilator administration.

To determine the efficacy and safety of Salmeterol/Fluticasone Propionate 50/500ug BID vs Ipratropium/Albuterol 36/206ug QID in Chinese patients with moderate-to-severe Chronic Obstructive Pulmonary Disease (COPD).

Chronic obstructive pulmonary disease is characterized as inflammatory airway with not fully reversible airflow limitation.Combination treatment with inhaled corticosteroid (ICS) and long-acting β2 agonists (LABA)attains an improved control of symptoms and lung function, that are superior to those associated with either drug alone. However, the treatment efficacy between high and medium dose of inhaled corticosteroid in combination of LABA is still unknown. The aim of the current study is to investigate the treatment efficacy with high and medium dose of fluticasone in combination with salmeterol in COPD patients.

Nowadays it has become evident that a chronic systemic inflammation is present in patients suffering from chronic obstructive pulmonary disease (COPD). The role of the nuclear enzyme poly(adenosine diphosphate-ribose)polymerase (PARP) as a key mediator within these systemic inflammatory processes as well as in COPD associated exercise intolerance and muscle weakness could recently been identified. The attenuating effect of dietary ingredients with PARP inhibiting activity on systemic inflammation was supported by data from in vitro and in vivo studies, from other groups as well as from our own lab. We identified several caffeine metabolites as potent inhibitors of the most abundant PARP-isoform PARP-1 in-vitro, in animal models as well as in ex-vivo experiments with whole blood from COPD patients. However, clinical data with respect to their anti-inflammatory effects in COPD patients are currently not available for none of these substances. Therefore, the current clinical pilot study is intended to establish for the first time clinical data (proof of principle) on the anti-inflammatory potential of caffeine metabolites.

COPD is a progressive pulmonary disease that is characterized by an inflammatory process in the airways and the lungs which leads to progressive airway obstruction. The inflammation is associated with tissue loss and remodelling. The investigators hypothesized that doxycycline reduces neutrophilic airway inflammation in patients with COPD. Therefore the investigators will conduct a randomized trial of doxycycline in 30 patients.

Emphysema is a lung disease that involves damage to the air sacs in the lungs and can lead to breathing difficulties. Treatment options for people with emphysema include pulmonary rehabilitation, lung volume reduction surgery, and lung transplantation. This study will observe people with emphysema to assess the effect of these treatment therapies on their quality of life and long-term health.

The purpose of this study is to assess the efficacy of a new treatment algorithm for bronchoscopic lung volume reduction (BLVR) in patients with emphysema based on the information of emphysema heterogeneity, destruction score, and fissure analysis.

The purpose of this study is to determine if educational intervention is effective in reducing exacerbations of chronic obstructive pulmonary disease in patients with low-risk disease.
