Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Chronic Obstructive Pulmonary Disease (COPD) is the fourth leading cause of death in the world and further increase in its prevalence and mortality has been predicted. Currently, the main long-term treatments are the long-acting beta-2 agonist, indacaterol, salmeterol and the anticholinergic drug, tiotropium and glycopyrronium, used alone or in combination: long-acting beta-2 agonist with corticosteroid (e.g. salmeterol/fluticasone), long-acting beta-2 agonist with anticholinergic (e.g. indacatetrol/glycopyrronium). These drugs are delivered to the lung using different inhaler devices such as Breezhaler ®, Handihaler® and Diskus®.

This is a First in Human study to assess the safety and tolerability of AZD7624, following inhaled administration of single ascending doses in healthy male volunteers and female volunteers of non-child bearing potential. Pharmacokinetics (what the body does to the drug) and pharmacodynamic (what the drug does to the body) parameters will be also assessed as secondary objectives.

Among many other causes, Bronchial obstruction in Chronic Obstructive Pulmonary Disease (COPD) is also caused by inflammation of peripheral airways walls. Neutrophils and other inflammatory mediators like Interleukin-6 (IL6), Interleukin-8 (IL8), Interleukin-1 alpha (IL-1 alpha),Interleukin-1beta (IL-1 beta), Tumor Necrosis Factor alfa (TNF-alfa), Reactive Oxygen Species (ROS), Leukotriene B4 (LTB4), Nitric Oxyde (NO) are implicated in the inflammation. NO is produced in response to physical and chemical stress on bronchial epithelium and plays a critical role in small airways remodelling Exhaled NO concentration is usually used to monitor bronchial inflammation The relationship between stretch and strain of small airways and bronchial inflammation is not well understood. The investigators hypothesis is that cyclic opening and closure of peripheral obstructed airways through the consequent stretching and strain acting on them can provoke an inflammatory response which can be monitored by exhaled NO. The pharmacological effects of bronchodilators may play a role on bronchial inflammation by reducing the stretching stress on bronchiolar walls thus reducing the production of NO in exhalate Data about these physiopathological aspects is missing in literature.

The aim of this study is to determine whether common CYP1A2 and CYP2E1 gene polymorphisms effect metabolism of theophylline in chronic obstructive pulmonary disease patients.

The purpose of the study is to determine the efficacy of mindfulness-based cognitive therapy (MBCT) as an add-on to pulmonary rehabilitation (treatment as usual, TAU) in chronic obstructive pulmonary disease (COPD). The investigators hypothesize that compared to treatment-as-usual, the add-on of MBCT will result in improved psychological (anxiety, depression) and physical outcomes (physical health status, activity level, inflammatory markers). Furthermore, the investigators will explore the possible moderating role of individual differences in sociodemographic and disease-related characteristics and the perceived quality of the therapeutic alliance, as well as the mediating role of mindfulness, breathlessness catastrophizing, self-efficacy, and self-compassion for the hypothesised effect.

This is an early feasibility study to investigate whether transcutaneous electrical stimulation applied to the abdominal wall muscles synchronous with voluntary exhalation can be used to support ventilation and affect hyperinflation in patients with chronic obstructive pulmonary disease. As part of this study, the effect of a range of stimulation intensities and stimulation timing profiles will be explored.

GSK573719 is a high-affinity specific muscarinic receptor (mAChR) antagonist which is being developed for the treatment of chronic obstructive pulmonary disease (COPD). The long duration of action of GSK573719, when administered via inhalation to humans supports the potential for use as a long acting bronchodilator.This is a randomized, double-blind, placebo-controlled, 5 period cross-over study in healthy male and female volunteers. The study will measure lung function after single inhaled doses from two configurations of the Novel Dry Powder Inhaler. Key assessments will include clinical relevant PD parameters: sGaw, FEV1

The aim of PR1MaC is to establish a clinical intervention that will adapt and permanently integrate rehabilitation services into primary care settings, which would be the reference point in the health care system for people with Chronic diseases (CD). More specifically, the intervention will aim to: (1) clinically operationalize the mechanisms and tools necessary for delivery of integrated CD services, promoting continuity of care in response to the needs expressed by stakeholders; (2) implement and deploy rehabilitation services adapted to the realities of various clinical primary care settings and develop tools to ensure the sustainability of interventions beyond the rehabilitation period; and (3) support clinical primary care teams in the acquisition and maintenance of evidence-based practices for the targeted CDs.

Study to assess effect of Fluticasone Propionate on acute lung inflammation following inhaled lipopolysaccharide (LPS) challenge. Study will be conducted in healthy volunteers. Assessment of inflammation will be via sputum induction.

Aim The purpose of this study is to evaluate whether fuel subsidies reduce exacerbations of COPD among people aged over 55, and therefore whether providing such subsidies is a cost-beneficial policy initiative. The Warm Homes for Elder New Zealanders Study enrolled community-dwelling people aged over 55 with moderate or worse COPD. Prior to the study commencing the houses were insulated (if feasible, & the house-owner agreed). Data were collected on the health and energy use of the participants. The households randomly assigned to the "early" intervention group had a subsidy to their power account their first winter in the study. The subsidy was the intervention and was designed to enable the participants, if they chose to do so, to keep their house warmer during the winter.
