Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

The purpose of this study was to assess global ventilated lung volume in moderate to severe COPD patients using MRI lung imaging after treatment with QVA149 compared to placebo.

The purpose of this study is to investigate whether flutiform® is effective and safe in the treatment of chronic obstructive pulmonary disease (COPD).

Difficulty falling asleep, staying asleep or poor quality sleep (insomnia) is common in people with chronic obstructive pulmonary disease. Insomnia is related to greater mortality, with four times the risk of mortality for sleep times < 300 minutes. Insomnia is also related to greater morbidity, with 75% greater health care costs than people without insomnia. However, insomnia medications are used with caution in COPD due to potential adverse effects. Common features of COPD such as dyspnea, chronic inflammation, anxiety and depression also affect insomnia and can interfere with therapy outcomes. While cognitive behavioral therapy for insomnia (CBT-I), a therapy that provides guidance on changing unhelpful sleep-related beliefs and behavior, is effective for people with primary insomnia and people with other chronic illnesses, the efficacy and mechanisms of action of such a therapy are yet unclear in people with both insomnia and COPD. The objective in this application is to rigorously test efficacy of two components of insomnia therapy - CBT-I and COPD education (COPD-ED) - in people with coexisting insomnia and COPD, and to identify mechanisms responsible for therapy outcomes. The central hypothesis is that both CBT-I and COPD-ED will have positive, lasting effects on objectively and subjectively measured insomnia and fatigue. The rationale for the proposed study is that once the efficacy and mechanisms of CBT-I and COPD-ED are known, new and innovative approaches for insomnia coexisting with COPD can be developed, thereby leading to longer, higher quality and more productive lives for people with COPD, and reduced societal cost due to the effects of insomnia. The investigators plan to test our central hypothesis by completing a randomized controlled comparison of CBT-I, COPD-ED and non-COPD, non-sleep health education attention control (AC) using a highly efficient 4-group design. Arm 1 comprises 6 weekly sessions of CBT-I+AC; Arm 2=6 sessions of COPD-ED+AC; Arm 3=CBT-I+COPD-ED; and Arm 4=AC. This design will allow completion of the following Specific Aims: 1. Determine the efficacy of individual treatment components, CBT-I and COPD-ED, on insomnia and fatigue. 2. Define mechanistic contributors to the outcomes after CBT-I and COPD-ED. The research proposed in this application is innovative because it represents a new and substantive departure from the usual insomnia therapy, namely by testing traditional CBT-I with education to enhance outcomes.

The purpose of this 12 week study is to evaluate the effects of the addition of umeclidinium bromide (62.5mcg) once-daily to fluticasone propionate (250/50mcg) twice-daily and umeclidinium bromide (125mcg) once-daily to fluticasone propionate (250/50mcg) twice-daily with placebo when added to fluticasone propionate (250/50mcg) twice-daily on lung function, COPD-related health status assessments and safety in COPD subjects.

This study will assess the efficacy, safety and tolerability of QVA149 in patients with moderate to very severe COPD.

Background: The efficiency of Neural respiratory drive (NRD)expressed by a ratio of ventilation to the diaphragm electromyogram (EMGdi) decreases in patients with COPD .Improving the neural respiratory drive efficiency of COPD will help to relieve the clinical symptom and make the patients feel comfort.Noninvasive positive pressure ventilation(NPPV)is a good treatment to AECOPD patients.It is unknown the effects of different mode of noninvasive positive pressure ventilation(NPPV) such as proportional assist ventilation (PAV) and pressure-support ventilation (PSV) on the efficiency of Neural drive of AECOPD and which mode benefit the patients more. Objective: To compare the short-term effects of mask pressure support ventilation (PSV) and proportional assist ventilation (PAV) on Neural respiratory drive in recovering patients of AECOPD

The purpose of this study is to assess the control of COPD using a symptom and exacerbation risk based treatment strategy based on GOLD 2011. This study is conducted in Japanese subjects with COPD and assess whether the GOLD 2011 strategy is effective in medical practice in Japan.

This is a multi-centered, randomized, placebo-controlled, double-blind, parallel group, trial evaluating 2 doses of mepolizumab against placebo given every 4 weeks through subcutaneous (SC) injection. In severe COPD subjects, sputum eosinophils levels are elevated to similar levels as those seen in severe asthmatics. It is hypothesized that the reduction of eosinophils with mepolizumab in COPD subjects would translate into a reduction of COPD exacerbations. The study will evaluate the efficacy and safety of mepolizumab, in subjects who are at or above the baseline blood eosinophil count of at least 150 cells/microliters who exacerbate despite regular use of maximal tolerated therapy, appropriate for severe COPD subjects, in the 12 months prior to study start. In total, 660 subjects will be randomized in 1:1:1 ratio to receive mepolizumab 300 mg, mepolizumab 100mg, or placebo administered SC. The total duration of subject participation will be approximately 62 weeks, consisting of a 1 to 2 week screening period, 52-week treatment period and 8-week follow-up period.

About 1 million individuals in the US have a prescription for supplemental oxygen (O2). Using O2 can prolong life and increase quality of life. Patients often do not use their oxygen as prescribed, which means that they are not benefiting as much as they could be from this therapy. The purpose of this study is to evaluate whether a PEer-Led O2 Infoline for patients and CAregivers (PELICAN) will increase adherence to supplemental oxygen prescription and improve health in patients with chronic obstructive pulmonary disease (COPD).

The purpose of the study is to investigate the efficacy and safety of fluticasone furoate/vilanterol Inhalation Powder compared with placebo over a 24 weeks treatment period in subjects of Asian ancestry with Chronic Obstructive Pulmonary Disease (COPD).
