Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Patients with Chronic Obstructive Pulmonary Disease (COPD) suffer from frequent and recurrent acute exacerbations (AECB) which are associated with enormous healthcare expenditures and significant morbidity, specifically an increased risk of death, a decline in pulmonary function and a significant change in quality of life. Bacteria appear to have an important role in acute exacerbations in chronic bronchitis and COPD. Studies of acute exacerbations in COPD have shown a reduction in bacterial load with prolonged exacerbation-free interval. In addition, recent studies indicate that acquisition of a new strain of H. influenzae, M. catarrhalis, S. pneumoniae or P. aeruginosa are responsible for many of these exacerbations. Chronic inflammation and bacterial infection predispose many patients to frequent and recurrent acute exacerbations. Mpex, (the sponsor on record at time of the study's initial registration) believes that intermittent administration of inhaled MP-376 in high risk patients will decrease the incidence of acute exacerbations by both by lowering the organism burden, and resultant inflammation, as well as pre-emptive eradication of any newly acquired bacterial strains.

Tadalafil may lower the pulmonary artery pressure in patients with Chronic Obstructive Lung Disease and secondary pulmonary hypertension and thereby improve patients quality of life.

Randomized, placebo controlled trial evaluating efficacy of dexamethasone in preventing sleep related breathing disturbances in lowlanders with chronic obstructive lung disease travelling from 700 m to 3200 m.

This study will compare the efficacy of indacaterol versus placebo (i.e., rescue medication only) and tiotropium in patients with Chronic Obstructive Pulmonary Disease (COPD) who have not received maintenance COPD medication for at least 12 months prior to entry (described hereafter as "maintenance naïve", see inclusion criteria).

The purpose of this study is to prospectively evaluate the safety and efficacy of the AeriSeal System in patients with advanced Non-Upper Lobe Predominant Heterogeneous Emphysema.

The purpose of this study is to determine whether pro-adrenomedullin (Mr proADM)in addition to clinical evaluation is effective to predict outcome of acute exacerbations of COPD patients visiting the emergency room(ER).

To study the effects of early exercise training in hospitalized patients for Chronic Obstructive Pulmonary Disease exacerbation (COPD). Interventions are randomized. In one group, early exercise training (aerobic and strength) during hospitalization for COPD exacerbation followed by exercise training at home until 30 days to discharge and in the other the intervention is usual care. In both groups, usual respiratory physiotherapy techniques during hospitalization and adequate physical activity recommendations have been included. The main variable is the increase in moderate or vigorous daily physical activities at 30 days after discharge.

This trial will evaluate the effect of acetazolamide (375 mg per day) vs. placebo on lung water content by ultrasound at acute altitude exposure in patients with Chronic Obstructive Pulmonary Disease (COPD).

Delivery of inhaled short-acting bronchodilators (SABD) is standard of care in the emergency department (ED) for exacerbation of COPD, the goal of such being rapid reversal of airflow obstruction. However, current guidelines for the delivery of SABDs in spontaneously breathing patients make no distinction whether these medications should be delivered via metered dose inhaler (MDI) or jet nebulizer (JN), the specific medication delivery device having no significant effect on hospital admission or reversal of flow obstruction. However, advancements in nebulizer design, namely FDA-approved vibrating mesh technology, have demonstrated significant improvements relative to JNs and metered dose inhalers in efficiency and amount of drug delivered in in vivo and in vitro studies. Currently there are no clinical trials comparing the use of vibrating mesh nebulizers (VMN) to JNs and their effect on clinically important outcomes. This prospective randomized controlled pilot trial seeks to determine if there are differences in hospital admission due to COPD when a vibrating mesh nebulizer is used versus a jet nebulizer.

This is a multicenter, single-arm trial to evaluate the safety and efficacy of inhaled treprostinil in subjects with pre-capillary pulmonary hypertension (PH) associated with Chronic Obstructive Pulmonary Disease (COPD).
