Active clinical trials for "Lung Diseases, Obstructive"

This study compared the efficacy of indacaterol versus placebo in COPD patients classified as GOLD 2014 Patient Group B. This was a 2-arm parallel group study that recruited COPD patients classified by GOLD Patient Gorup B. On successful completion of run-in period, patients were randomized in the ratio 1:1 to receive prn salbutamol plus: Indacaterol 150ug or Placebo for indacaterol all once daily (od) for 26 weeks. The primary objective (trough FEV1) was assessed after 12 weeks.

Chronic obstructive pulmonary disease (COPD) are characterized by frequent relapses, often resulting from common bacterial infections. Enhancing the immune response in these patients may decrease the frequency of these relapses. The use of a mechanic Polyvalent Bacterial Lysate (PMBL, Ismigen, 13 bacterial strains)may enhance the immune response and therefore help significantly to the control of relapse in these patients. In the current study the effect of the administration of the PBML to patients older than 40 years, with moderate, severe or very severe COPD, in good or discrete physical condition on the number of relapses in an observation period of 12 months. In addition, the effect of the PMBL on the duration of the interval between relapses, on relapse symptoms, on the use of other drugs, on the number of days of absence of work, on the number of hospitalizations and duration thereof and on potential toxicity of the treatment.

The purpose of this research study is to determine the effect of the environment on six-minute walk test performance in individuals with chronic obstructive pulmonary disease due to alpha-1 antitrypsin deficiency. The aim of the study is to determine the environmental impact on physical performance in this population to determine if any factors influence quality of life. This study was developed to evaluate the efficacy of the using the indoor six-minute walk test to determine eligibility for ambulatory oxygen therapy.

The purpose of this study is to measure the effectiveness and safety of TD 4208, an investigational drug being developed to treat people with moderate to very severe COPD, compared to placebo, a treatment without activity.

A number of studies have documented poor sleep quality and troublesome symptoms (breathlessness, cough and sputum production) upon awakening in patients with COPD. However, the investigators know very little about measurements of respiratory mechanics (i.e., lung volumes, respiratory pressures, diaphragm function, etc) during sleep in these patients. The investigators also know little about how modern bronchodilator therapies, or the timing of when they are taken, affect respiratory mechanics during sleep or the severity of early morning respiratory symptoms. COPD is often treated with inhaled bronchodilator medications which are used to open up airways and make it easier for air to get in and out of the lungs. The investigators are studying the effects of a new inhaler that contains two different types of long-acting bronchodilator: formoterol [a long-acting beta2-agonist (LABA)] and aclidinium bromide [a long-acting muscarinic antagonist (LAMA) or anticholinergic]. Initial studies have shown that this combination therapy taken twice daily can improve some lung function measurements and respiratory symptoms in patients with moderate to severe COPD. There are also reports that evening administration of this medication may provide important advantages in patients with dominant nighttime and early morning symptoms. It is thought that sustained bronchodilation and lung deflation during the night may improve respiratory mechanics, diaphragmatic function, pulmonary gas exchange, sleep quality, and reduce severity of morning symptoms. This study will be the first to explore the effects of a nighttime dose of aclidinium/formoterol combination therapy on detailed measurements of respiratory mechanics and early morning symptoms in COPD. This study will also give us a better understanding of the mechanisms of early morning respiratory symptoms and their improvement with bronchodilators.

This study evaluates the effect of vitamin D supplementation on outcomes of 10 weeks progressive strength training in 100 ageing subjects (>45 years of age). Participants will be recruited into two similarly sized strata; one containing COPD patients and one containing healthy subjects of similar age. In each stratum, half the participants will receive vitamin D supplementation and half the participants will receive placebo

The purpose of this research study is to determine the amount of medicine absorbed in the lungs following dosing via eFlow nebulizer and Seebri® Breezhaler® with and without activated charcoal in subjects with moderate to severe chronic obstructive pulmonary disease (COPD).

This is a multiple dose, randomized, parallel, double-blind, double-dummy, multicenter and multinational Phase III study to determine the efficacy and safety of Aclidinium bromide 400μg/Formoterol Fumarate (AB/FF) 12 μg compared to individual components and TIO (Tiotropium) 18 μg when administered to patients with stable chronic obstructive pulmonary disease (COPD).

The study was designed to investigate the efficacy and safety of different doses CHF5259 a long acting muscarinic antagonist in patients with moderate to severe COPD.

The principal objective is to show noninferiority of nebulized salbutamol through the high flow nasal system moistened AIRVO ™ 2 in terms of reversibility of airflow obstruction compared to nebulization by the usual method (spray mask).
