Brief Summary People with severe chronic obstructive pulmonary disease (COPD) often have too much air trapped in their lungs (pulmonary hyperinflation). This makes it hard to breathe and reduces quality of life. This study tests whether a single session with a medical device called Simeox® can reduce the amount of air trapped in the lungs. Simeox® works by applying gentle intermittent negative pressure during exhalation to help air move out of the lungs more easily. Patients with severe or very severe COPD and documented hyperinflation will undergo lung function measurements before and immediately after a 20-minute Simeox® session. The main measurement is the change in residual volume (RV), which is the amount of air left in the lungs after a full exhalation. We will also measure changes in other lung volumes, breathlessness, and any side effects. This is a single-arm pilot study enrolling 23 patients at one center in Italy (ASST Lodi). The study is non-profit and has been approved by the Ethics Committee Comitato Etico Territoriale Lombardia 1 (CET Lombardia 1).

NCT05607719
The study objective is to determine whether an ICS added for 4 weeks to a baseline treatment with a Long-Acting Beta-adrenergic Agonist (LABA) and Long-Acting Muscarinic Antagonist (LAMA) combination improves pulmonary vascular endothelial function as assessed by the vasodilator response to inhaled albuterol (endothelium-dependent vasodilation) in stable COPD patients treated with a LABA/LAMA without an ICS for at least one month.
NCT07646587
This study is trying to identify the right dose of a long-acting medicine called WIN378 for people with moderate - severe chronic obstructive pulmonary disease (COPD). WIN378 blocks the action of a protein called TSLP that causes inflammation in the lung and may contribute to COPD control and symptoms. The study will test how doses of WIN378 are handled by the body (pharmacokinetics) and assess the safety of the medicine and markers of COPD inflammation in exhaled breath and blood, lung function and COPD control (pharmacodynamics)
NCT05743582
Chronic Obstructive Pulmonary Disease (COPD) causes obstruction to airflow when breathing out. It is a leading cause of chronic lung disease, hospitalization and death. Smoking is the major cause of COPD but why some smokers develop COPD while others do not is poorly understood. A central feature of COPD is accumulation of inflammatory blood cells, macrophages and neutrophils, in the airway, leading to lung injury and airway damage. The small airways of many patients with COPD contain bacteria, which are absent in healthy smokers or non-smokers. These bacteria stimulate recruitment of neutrophils, macrophages and other inflammatory cells, further accelerating airway injury. The investigators and others have shown resident macrophages in the lung and inflammatory cells (neutrophils and macrophages) recruited from the blood, which normally clear bacteria, have reduced anti-bacterial capacity in COPD and that their altered function impairs the resolution of inflammation. The investigators now wish to test why these cells fail to clear bacteria focusing in particular on how they use molecules as food to generate energy, a process termed metabolism, since this is an important determinant of immune cell function. Comparison will be made between lung resident cells (obtained by performing bronchoscopy and washing a segment of lung to flush out immune cells) and those from the blood to determine if the alterations are specific to the lung. The investigators will identify alterations in responses to bacteria in relation to changes in metabolism . A major focus will be on how structures in the cell that normally are key for energy production (i.e. mitochondria) become dysfunctional and how this impacts responses to bacteria. The investigators will relate findings to the clinical features of COPD and to healthy non-smokers and smokers to separate smoking-related changes from COPD. The aim is to develop new approaches with which to treat and manage COPD.

NCT07047092
Chronic obstructive pulmonary disease (COPD) is a major public health problem with 212.3 million prevalent cases of COPD worldwide and 3.3 million deaths related to COPD in 2019. Obstructive sleep apnoea (OSA) is the most common sleep disordered breathing. It is estimated that almost 1 billion adults have OSA worldwide. Given the increasing prevalence of obesity, co-morbid OSA is frequently seen in patients with COPD. Co-morbid OSA has been shown to increase mortality, to reduce quality of life and to favour acute exacerbation of COPD. For those admitted for a life-threatening exacerbation of COPD requiring an intensive care admission for acute hypercapnic failure, they are more likely to get readmitted. For those admitted for an acute exacerbation in any ward, they are more likely to be re-admitted for another exacerbation within 180-days if their OSA is not treated. Unfortunately, data regarding the best management of OSA in patients with co-morbid COPD are lacking as they were often excluded from clinical trials involving patients with COPD. Therefore, CPAP or NIV are administered without scientific evidence establishing which treatment is the most appropriate.
NCT01692444
Airway remodelling is an abnormal tissue repair following bronchial inflammation, which contributes to none reversible pathological features, such as bronchial and peri-bronchial fibrosis. It also influences the prognosis of Chronic Obstructive Pulmonary Disease (COPD) and its mechanisms remain largely unknown. The role of fibrocytes has been demonstrated in the pathophysiology of asthma, lung fibrosis or pulmonary hypertension. However, the recruitment of blood fibrocytes and their involvement in COPD airway remodelling remain unknown. The main objective of the study is to analyse the distribution and quantify the number of the peri-bronchial and blood circulating fibrocytes in patients with different stages of COPD compared to control subjects.

This study is researching a drug called dupilumab, referred to as "study drug". The study is focused on people diagnosed with COPD to determine if the study drug, in addition to standard of care treatment for COPD, might reduce the reoccurrence of a COPD exacerbation (a "flare-up") happening within the study treatment duration (around 90 days). The study is looking at another research question: • What side effects may happen from taking the study drug
NCT07579052
This prospective observational cohort study aims to prospectively evaluate and validate the Clinical Load, Exchange, Ability of Respiration, and Reserve (CLEAR) model for predicting sustained ventilatory liberation in patients with severe chronic obstructive pulmonary disease (COPD) receiving invasive mechanical ventilation (MV) or non-invasive ventilation (NIV). Two parallel cohorts will be studied: CLEAR-MV for patients undergoing spontaneous breathing trials (SBT) and CLEAR-NIV for patients undergoing NIV withdrawal trials. The model integrates diaphragm ultrasound evaluating diaphragm thickening fraction (DTF), ventilatory load indices including the rapid shallow breathing index (RSBI) or Clinical Load Index (CLI), gas exchange parameters including Potential of Hydrogen (pH), partial pressure of carbon dioxide (PaCO₂), and its change over time (ΔPaCO₂) combined as the Gas Exchange Index (GEI), and peripheral muscle reserve assessing rectus femoris (RF) and vastus intermedius (VI) thickness. The primary outcome is successful liberation from ventilatory support within 72 hours. Secondary outcomes include ventilatory failure within 7 days, ventilator- or NIV-free days at 28 days, and time-fixed 90-day clinical outcomes including all-cause mortality, sustained ventilatory independence, and rehospitalization for respiratory failure. Model performance will be evaluated using discrimination (area under the receiver operating characteristic curve), calibration (calibration intercept and slope), and clinical utility (decision curve analysis and net benefit) and compared with prespecified established ventilatory indices, including the Rapid Shallow Breathing Index (RSBI) and Integrative Weaning Index (IWI) in the invasive mechanical ventilation cohort, and the Heart rate, Acidosis, Consciousness, Oxygenation, and Respiratory rate (HACOR) score and the ratio of peripheral oxygen saturation to fraction of inspired oxygen divided by respiratory rate (ROX) index in the non-invasive ventilation cohort.

NCT05061368
Chronic obstructive pulmonary disease (COPD) is a condition characterized by airway obstruction. Patients with COPD experience significant shortness of breath on exertion. The mechanisms responsible for shortness of breath on exertion are well understood in moderate and severe COPD, but, are poorly understood in mild COPD where symptoms appear disproportionate to the degree of airway obstruction. Mild COPD patients show an exaggerated breathing response to exercise, determined by the breathing response to carbon dioxide production (V̇E/V̇CO2). Recent work suggests that the increased V̇E/V̇CO2 during exercise in mild COPD is secondary to increased deadspace (i.e. lung regions with ventilation but no perfusion) and/or ventilation/perfusion (V̇A/Q) inequality (poor matching of ventilation to perfusion). Researchers have proposed that the increased deadspace or V̇A/Q inequality is secondary to pulmonary vascular dysfunction and hypoperfusion of the pulmonary capillaries. Recently, we have shown that inhaled nitric oxide, a potent dilator of pulmonary vasculature, reduces shortness of breath and V̇E/V̇CO2, and improves exercise capacity in mild COPD. This preliminary finding suggests that pulmonary vascular dysfunction is an important contributor to exercise intolerance in mild COPD. Here, we aim to test whether sildenafil, an oral pulmonary vasodilator, can improve exercise tolerance and shortness of breath in mild COPD.

NCT05516316
This study aims to assess the effect of EP395 against an induced inflammation of the lung. In addition, further data about the safety and tolerability of EP395 will be collected. To investigate the efficacy of EP395 at the end of the treatment with EP395 or placebo (dummy), all participants will inhale a lipopolysaccharide (a molecule composed of sugar and fat) that artificially induces an acute inflammation of the airways. It is assumed that participants who received EP395 will show less inflammation of the airways than participants who received placebo.
