Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

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.

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.

A randomized controlled trial in which icing and airflow stimulation for reduction of dyspnea in patients of obstructive lung disease was done which is characterized as condition of infection described by constant improvement of perpetual constraint of flow of air that is partially reversible and incorporates chronic bronchitis, emphysema and small airway diseases . The tools used were RR, Spirometry, Saturation, Borg Scale, MRC scale, shuttle walk test and St George's Respiratory Questionnaire (St.GRQ) score. Pulse oximeter measured the saturation levels and respiratory rates were alse observed. Borg scale measured rate of perceived exertion ranges from 6(easy physical activity) and 20(worst activity) and MRC measure dyspnea levels. In St.GRQ score between 1 to 8 is symptoms related and 9 to 17 was activity related.Literature review indicate that icing and airflow stimulation reduce dyspnea in patients of obstructive lung diseases.

Ventilated by a single-limb tubing with PEV caused CO2 rebreathing to COPD patients during exercise with the increasing ventilation. The aim of this study was to evaluate whether CO2 rebreathing could be avoided with the use of the dual-limb circuit, to provide a theoretical basis of more rational clinical application of NIV in the setting of increasing ventilation(eg, after exercise).

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.

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.

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.

Introduction: Chronic obstructive pulmonary disease (COPD) is characterized by airflow obstruction, which is clinically manifested by dyspnea and leads the patient to a vicious cycle of sedentary lifestyle. Pulmonary rehabilitation (PR) is an important therapeutic strategy to break this cycle. Cardiovascular diseases are frequent in patients with (COPD) and are associated with higher mortality. The effects of (PR) on cardiovascular risk factors in patients with (COPD) have been little studied so far. Objectives: To evaluate the effects of pulmonary rehabilitation compared to the control group on cardiovascular risk factors in patients with (COPD). Methods: A randomized clinical trial will be conducted. Patients with (COPD) will be divided into two groups: Group I (GI): group that will be rehabilitated, with 3 weekly sessions, for 8 weeks and Group II (GII): control group, without intervention. In both groups, a baseline evaluation will be performed, which will be repeated after 9 weeks and consists of: clinical and laboratory parameters, endothelial function (FMD) and brachial ankle index (ABI). Outcomes commonly used in the assistance to assess (PR) will also be measured. Expected Results: The study is expected to improve understanding of the impact of (PR) on cardiovascular variables in patients with (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.
