Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Chronic obstructive pulmonary disease (COPD) is a significant cause of morbidity and mortality worldwide. In contrast to other chronic diseases, COPD is increasing in prevalence and is projected to be the third-leading cause of death and disability worldwide by 2030. The costs to society for treating COPD are high, accounting for approximately 3.4% of the total health care budget of the European Union. Acute exacerbations of COPD (AECOPD) are responsible for a large portion of the economic burden of COPD. More than 500,000 hospitalisations and 100,000 deaths are attributed to AECOPD in the US each year. In addition to a substantial economic burden, AECOPD is also responsible for much of the morbidity and mortality from COPD. Interleukin-33 (IL-33) is an alarmin released from the epithelium following damage. IL-33 is an IL-1 family alarmin cytokine constitutively expressed at epithelial barrier surfaces where it is rapidly released from cells during tissue injury. IL-33 signals through a receptor complex of IL-1 receptor-like 1 (IL1RL1) (known as ST2) and IL-1 receptor accessory protein (IL1RAcP) to initiate MyD88-dependent inflammatory pathways. The role of the IL33/ST2 axis in COPD is uncertain. IL33 has been implicated in eosinophil recruitment to the airway and maturation in the bone marrow largely via its effects upon innate lymphoid cells. IL33 increased following experimental cold in asthma and thus might play a role in the consequent inflammatory response and possible susceptibility to secondary bacterial infection in obstructive lung disease. Both eosinophilic inflammation and viral infection drive COPD exacerbations and therefore targeting the IL33/ST2 axis might reduce COPD exacerbations. The main aim of this trial is to evaluate whether anti-ST2 will impact on airway inflammation in COPD and therefore reduce the frequency of exacerbations. For the purposes of this trial, exacerbations are defined as flare-ups of symptoms involving the use of healthcare resulting in treatment with steroids and/or antibiotics and/or hospitalisation or death due to COPD.

This is a randomised, controlled, two period cross-over, 4 weeks chronic dosing, study to evaluate the effects of Budesonide/Glycopyrronium/Formoterol Fumarate (BGF) and Glycopyrronium/Formoterol Fumarate (GFF) on airway dimensions.

AZD8871 is a new chemical entity possessing long-acting dual-pharmacology (muscarinic receptor antagonist and β2 adrenoceptor agonist [MABA]) in a single molecule. This type of agent presents a novel approach to the treatment of chronic obstructive pulmonary disease (COPD) and potentially asthma (in combination with an inhaled corticosteroid). AZD8871 is being developed for inhalation, formulated with alpha lactose monohydrate and delivered by dry powder inhaler (DPI) that allows delivery of a single dose of the study drug. The primary objective is to investigate the safety and tolerability of AZD8871 at steady state in healthy male Japanese subjects.

This is a phase IIIb randomised, double-blind, double-dummy, multicentre, parallel group, 24 week study to assess the efficacy and safety of Glycopyrronium/Formoterol Fumarate (GFF) fixed-dose combination 7.2/4.8 μg 2 inhalations twice daily compared to Umeclidinium/Vilanterol (UV) 62.5/25 μg fixed-dose combination 1 inhalation once daily in Patients with moderate to very severe COPD.

Inspiratory muscle training（IMT）was an rehabilitation therapy for stable patients with chronic obstructive pulmonary disease(COPD). However, its therapeutic effect remains undefined due to unclear of diaphragmatic mobilization during IMT. Diaphragmatic mobilization represented by transdiaphragmatic pressure（Pdi）and neural respiratory drive expressed as corrective root-mean-square(RMS) of diaphragmatic electromyogram(EMGdi) provide vital information to select the proper IMT device and loads in COPD, therefore make curative effect of IMT clarity. Pdi and RMS of diaphragmatic electromyogram (RMSdi%) was respectively measured and compared during inspiratory resistive training and threshold load training in stable patients of COPD.

This study aims to assess the effect of nasal high flow oxygen therapy on regional function measured by volumetric computed tomography, in patients with chronic obstructive pulmonary disease.

The primary purpose of this study is to assess the effectiveness of TRELEGY ELLIPTA relative to non-ELLIPTA Multiple Inhaler Triple Therapies (MITT) for Chronic Obstructive Pulmonary Disease (COPD) control within the usual clinical practice setting. The study will be conducted once TRELEGY ELLIPTA has been approved in the countries in which the study will be conducted and is available commercially. This is a randomized, open-label, effectiveness, phase 4 study of 24 weeks' duration in COPD subjects to evaluate TRELEGY ELLIPTA (fluticasone furoate [FF]/vilanterol [VI]/umeclidinium bromide [UMEC]: 100 microgram [mcg]/62.5 mcg/25 mcg) inhalation powder taken once daily using a single ELLIPTA inhaler compared with any non-ELLIPTA MITT in the usual care setting. Effectiveness of TRELEGY ELLIPTA will be assessed by comparing proportion of COPD Assessment Test (CAT) responders at Week 24 between two treatment groups. TRELEGY and ELLIPTA are trademarks of GlaxoSmithKline (GSK) group of companies. The study will enroll approximately 3000 subjects.

GSK2269557 is being developed as an anti-inflammatory agent for the treatment of chronic obstructive pulmonary disease (COPD) and other inflammatory lung diseases such as asthma. This study is designed to investigate the recovery, excretion, and pharmacokinetics (PK) of (14 Carbon [C])-GSK2269557 administered as a single intravenous (IV) dose (concomitant with an inhaled non-radiolabelled dose) and as a single oral dose in 6 healthy male subjects. Subjects will receive [14C] radiolabelled GSK2269557 administered as IV infusion, with a nonradiolabelled dose of GSK2269557 via dry powder inhaler (DPI) in treatment period 1 and a single dose of [14C]-GSK2269557, administered as an oral solution in treatment period 2. There will be a washout period of at least 14 days after inhaled and IV dosing before subjects takes part in treatment period 2. The IV microtracer dose of GSK2269557 will be administered concomitant to an inhaled non-radiolabelled dose to ensure that the pharmacokinetics represent a clinically relevant dose. The total study duration will be up to 11 weeks, including a screening visit, 2 treatment periods and a follow-up visit.

Chronic obstructive pulmonary disease (COPD) is a major health problem. Acute exacerbations are a health-care burden involving frequent hospitalizations and elevated costs. They have effective therapies with significant side effects. Acupuncture has been shown to reduce dyspnea and other COPD-related symptoms. The investigators will compare the efficacy and safety of the addition of true acupuncture to usual care with both sham-acupressure added to usual care and usual care only for the treatment of acute exacerbations of COPD among inpatients.

Humidified Nasal High-flow with Oxygen (HNHF-O2) therapy has been reported to have acute beneficial effects in patients with hypoxemic respiratory failure who have been hospitalized. The usefulness of this therapy in the outpatient setting is unproven. This pilot study will test the feasibility of using this therapy in the outpatient setting and its effects on sleep.
