Active clinical trials for "Lung Diseases, Obstructive"

The objective of this study is to test the effect of High Molecular Weight Hyaluronic Acid (HMW-HA) on Non Invasive Ventilation (NIV) effectiveness in patients admitted to a sub-intensive care unit for respiratory failure due to acute exacerbation of Chronic Obstructive Pulmonary Disease (COPD).

Oxygen supplementation has been proven to be effective in hypoxemic COPD patients by increasing oxygenation and reducing dyspnea. In clinical practice there are three common oxygen delivery systems used: continuous oxygen flow (CF), demand oxygen delivery with liquid oxygen (DDL) and demand oxgen delivery with portable oxygen concentrator (DDC). The CF involves considerable wastage of oxygen because oxygen is supplied during in- and exhalation. Demand oxygen delivery saves oxygen and results in a comparable oxygen saturation at rest in COPD patients. However, it is unknown, if oxygen supplementation via demand oxygen delivery is also sufficient during exercise in hypoxemic COPD patients. In addition, it has to be considered that the lower weight of demand oxygen delivery system might enable patients for higher physical activity level and mobility in daily life. The effects of These three oxygen delivery systems shall be investigated by a randomized, controlled cross-over Trial. Every patient has to perform an Incremental Shuttle Walk Test and three Endurance Shuttle Walk Tests with three different oxygen supplementation (via CF, DDL or DDK) in randomized order.

To evaluate the efficacy, safety and tolerability of multiple doses of QBW251 vs placebo administered orally, on airway function, lung volume, and quality of life in patients with chronic obstructive pulmonary disease (COPD)

This mechanistic study is a single-center, randomized, double-blind, placebo-controlled, cross-over study to evaluate the effect of dual bronchodilation with QVA149 on cardiac and lung function parameters in hyperinflated COPD patients.

This is a Phase I open-label, single center study to assess the PK and safety of BGF MDI 320/14.4/9.6 µg in subjects with moderate to severe COPD. Pharmacokinetics will be assessed following a single dose administration on the first treatment day (Day 1) and will be assessed again after 7 days of repeat dosing. This study includes a Screening Period of up to 28 days and a single Treatment Period of 8 days. A follow-up phone call will be conducted at least 5 days but no longer than 7 days after the last dose of study drug.

The study assessed the safety and ability of an orally inhaled medicine [i.e., Glycopyrrolate Inhalation Solution = GIS] to improve airflow in the lungs when delivered using an eFlow nebulizer in 42 patients with Chronic Obstructive Pulmonary Disease (COPD). Each patient randomly received several, single doses of GIS, or placebo, separated by approximately 1 to 2 weeks. After the dose was given, lung airflow was measured over 24 hours and blood was collected to measure how much GIS was in the bloodstream. The study was conducted to find the once-a- day GIS dose that produced the highest improvement in lung airflow using the eFlow nebulizer.

Respiratory muscle weakness and fatigue are related to clinical deterioration in patients with Chronic Obstructive Pulmonary Disease (COPD). Respiratory muscle training (RMT) is a key therapeutic strategy in these patients. It is necessary therefore to increase its dissemination on a large scale, improve patient´s adherence and optimize the control of the implementation of training. The aim of this project was to design a RMT device including light and sound incentives, digital registration application and analysis of the training sessions, and studying the effectiveness of a new shortened RMT scheme of high intensity that could provide added value to enhance the implementation of training in patients with COPD. From an operational point of view, researches were organized into three packages of complementary work focused on the design of a new portable dual valve with electronic lighting and auditory incentives components. The conceptualization and design of a software to analyze the performance and individual continuous use of the valve, and the evaluation of the feasibility, safety and efficacy of a shortened schedule of respiratory muscle training in adult patients with COPD were realized.

The main purpose of the present study is to verify whether, as compared with conventional-intensity noninvasive positive pressure ventilation, high-intensity noninvasive positive pressure ventilation may more effective in correcting hypercapnia, hence reducing the need for intubation and improving survival in patients with acute exacerbation of chronic obstructive pulmonary disease.

This is a study to evaluate the effects of AZD8871 in patients with COPD. Adult male or female patients with moderate to severe COPD, who agree to be in this study, will receive 3 treatments, i.e. 2 different doses of AZD8871 and placebo (dummy medication containing no drug) at once a day for 2 weeks, in a random order. To make the comparison between AZD8871 and placebo as fair as possible, this study is "double blinded." This means that neither patient nor the study doctor will know in which order the 3 treatments will be given. This study will include patients who are between 40 and 80 years of age. In total there will be 42 patients participating in this study at two study centers in the United Kingdom and Germany. The study will have a total of 12 visits for each patient spanning for a period of 4 to 6 months. The study is anticipated to run for approximately 8 months and should not exceed 10 months.

The STAR-study (STay Active after Rehabilitation) investigates in a randomized controlled trial (RCT) the additional effect of a pedometer-based behavior change intervention (BCI) during in-patient pulmonary rehabilitation (PR) on objectively measured physical activity (PA) 6-weeks and 6-months post PR. The BCI uses the behaviour change techniques a) instruction on how, where and when to perform the behavior, b) prompt goal setting for physical activity, c) prompt self-monitoring of behavior and d) feedback on behavior. The primary outcome of PA will be measured using an accelerometer (Actigraph wGT3X) for a time period of seven days, firstly two weeks before rehabilitation begins (T0 = study phase I) as well as six weeks and six months (T3 and T4) after PR. Additionally to predict PA progression after PR, a complex personal diagnostic, including questionnaires as well as functional assessments, is to be carried out at the start (T1 = start of study phase II) and end of PR (T2). This diagnostic is based on the main ideas of the PA-related health competence model (PARC-model) and especially incorporates physical and psychological personal determinants of PA.
