Filter by:The purpose of this study is to evaluate the efficacy and safety of CHF 5259 (glycopyrrolate bromide) for the treatment of COPD patients.
This is a single-center, Phase I, healthy adult subject study with a randomized, double blind, three period, three-treatment, cross-over design.
The purpose of this study was to examine the characteristics of patients selected for treatment with roflumilast and the effectiveness and safety of roflumilast in patients with severe or very severe COPD treated in Hospital and outpatient specialist ward settings in Greece.
To answer the question whether a disease specific profile of breath in patients with COPD can be detected by an untargeted metabolomic study using exhaled breath analysis by mass spectrometry.
The improvement in inspiratory muscle function might result in beneficial changes in breathing pattern during whole body exercise. The hypothesis is the effect of inspiratory muscle training as an adjunct to a pulmonary rehabilitation program improves the breathing pattern during an incremental cycle exercise.
We aim to use an integrated network systems approach to analyze certain existing small airway epithelium (SAE) omic data sets at the genetic, epigenetic (methylation), gene expression, microRNA and metabolomic levels, to develop an initial model of network connectivities and key network pressure points relevant to SAE biology in health and disease.
- Chronic Obstructive Pulmonary Disease (COPD) is characterized by lung hyperinflation and flow limitation. These physiopathological modifications are secondary to loss of elastic recoil and bronchial obstruction due to emphysema. - The cornerstone of COPD treatment is represented by inhaled beta-2 agonists and anticholinergics. The molecules of the latter classes can be characterized by short lasting action (few hours), long acting action (12 hours) or ultra long acting duration of action (24 hours). - For years the only anticholinergic (or antimuscarinic) drug other than those used by aerosol, was Tiotropium Bromide. Recently two new antimuscarinic agents have been launched on the market: glycopyrronium bromide (once daily) and aclidinium (twice daily). - The Single Breath Nitrogen Test is capable of identifying the pulmonary closing volume. The part of the curve that reflects lung ventilation inhomogeneity is the slope of phase III - For COPD patients, the most important characteristic for an inhalatory drug is a prompt action in order to give a quick relief from respiratory symptoms, in particular dyspnoea. - The objective of this study is to study the acute action of glycopyrronium and aclidinium in terms of reduction of hyperinflation, pulmonary specific resistances, lung volume distribution and dyspnoea at rest in severe COPD patients. - To our knowledge no study has explored these aspects before.
The aims of the study are to: 1. Implement a telemonitoring programme in heart failure and obstructive pulmonary disease (COPD) /chronic respiratory patients by assessing the real world impact of on readmissions, consults, home visits, quality of life and economic endpoints. 2. Explore the effects of telemonitoring across heart and respiratory groups with respect to i) factors that influence how patients integrate telemonitoring into their daily routines and self care behaviour and ii) how healthcare professionals use telemonitoring to aid decision- making. 3. Understand the impact of telemonitoring on a variety of care pathways.
Rationale: The PneumRx RePneu Lung Volume Reduction Coil (RePneu LVR-coil) is a bronchoscopic lung volume reduction treatment designed to compress the areas of lung parenchyma most damaged by emphysema. The LVRC treatment was found to be feasible, safe and effective in previous studies. However, patient-based outcomes besides quality of life questionnaires are hardly measured after intervention treatments for COPD. Furthermore, the exact underlying physiological mechanism of the LVR-coil treatment is unknown. Another aspect of the treatment which we to date do not fully understand is which group of patients benefit of the treatment and which group of patients do not, this knowing that the responder rate is already about 60%. Objective: The objectives of the study are to gain more knowledge on 1) the effect of the LVRC treatment on patient-based outcomes like physical activity, 2) the underlying physiological mechanism of the treatment, 3) the predictors of response to the treatment at baseline, and 4) on a targetted treatment number of coils to be placed per lung using lung compliance. Study design: This study is a non-randomised open label multi-center intervention study. Study population: The study population exists of adult patients with severe emphysema with no other treatment options left besides surgical procedures. Intervention: Bilateral bronchoscopic lung volume reduction treatment with RePneu coils. Main study parameters/endpoints: The main study endpoint is the change in physical activity between baseline and 3 months follow-up after the second treatment. The secondary endpoints are the changes between baseline and 3 months follow-up after the second treatment in: patient reported outcomes of the treatment, dynamic lung hyperinflation, static lung volumes, lung compliance, diaphragm function, lung perfusion, systemic inflammation and small airways function. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The LVR Coil has been designed to be as safe as possible. It was shown that the risks associated with the LVRC system are largely attributable to the bronchoscopic procedure itself rather than to the device per se. Therefore, it appears that the LVRC device itself does not appreciably increase the risk of serious adverse events beyond the risk of undergoing a bronchoscopy procedure or simply having emphysema. Currently, this treatment is not commercially available in the Netherlands and study participants will have to visit the hospital multiple times. Previous studies have shown that the treatment has beneficial effect for the patient, however not all patients respond. Part of this new study is to try to identify which group of patients respond to the treatment and which patients do not. Therefore, it is possible that a patient will not receive any benefits from the treatment.
Quadricipital electrical stimulation added to respiratory rehabilitation in COPD patients. Quadricipital electrical stimulation (ES) in chronic obstructive pulmonary disease (COPD) patients has been demonstrated to improve both dyspnea and physical status. The aim of our study is to demonstrate that ES added to respiratory rehabilitation program induces a greater improvement on exercise tolerance in such patients. Design : 160 patients with severe COPD will be randomly assigned to 2 groups : either rehabilitation program (group 1), either ES and rehabilitation program (group 2). In both groups, rehabilitation program comprises endurance training, 18 - 24 sessions (6 - 8 weeks), health education, global muscular strengthening. In group 2, bilateral quadricipital electrical stimulation 30 min sessions is added 5 days / week. Subjects : COPD patients with FEV1 < 60% pred, FEV1/VC < 70%, and TLC > 80%, with dyspnea, in stable conditions, and 18 > BMI < 35 kg/m² . Intervention : 6 min walking distance, incremental exercise test data (aerobic capacity, work rate, ventilatory threshold), physical activity with activity monitor, health related quality of life will be determined before and after training. Abbreviations : FEV1 = forced expiratory volume in 1 sec; VC = vital capacity; TLC = total lung capacity; BMI = body mass index.
