COPD Chronic Obstructive Pulmonary Disease

Induced sputum is a non-invasive method to collect samples from the airways. It involves inhaling a saline mist to loosen mucus, which is then coughed up. The samples are used to study markers of lung disease. In some people, this procedure yields only small amounts of sample. This study looks at whether adding a vibroacoustic device during sputum induction can increase the amount of sputum collected in patients with chronic obstructive pulmonary disease (COPD). The device applies gentle sound-based vibrations to the chest to help move mucus in the airways. Each participant undergoes two sputum collection procedures on separate days: one with and one without the device. The order is assigned at random. The main comparison is the amount of sputum obtained with versus without the device in the same person. The study also assesses how well the procedure is tolerated.

Individuals with chronic obstructive pulmonary disease (COPD) often experience dyspnea, low physical activity, and reduced quality of life. RESP-FIT is a randomized controlled trial evaluating a remotely delivered respiratory muscle strength training intervention combined with mobile health tools to improve dyspnea, respiratory muscle strength, and physical activity in adults with COPD.

Aim: To compare gas exchange trends, clinical outcomes, and tolerability between HFNC and NIV in COPD patients with mild-to-moderate hypercapnic respiratory failure.

Background Patients with chronic obstructive lung disease (COPD) suffer from a progressive loss of lung function that leads to poor quality of life, and often invalidity and early death. This is markedly affected by a reduced exercise capacity and dyspnoea, but the underlying mechanisms are unknown. In the present study, we aim to investigate whether this may involve a reduced pulmonary blood volume secondarily to a reduced total blood volume. Methods Design: Prospective matched comparative study Intervention: None Outcomes: The primary outcome is pulmonary blood volume estimated to total blood volume ratio between patients with COPD and healthy controls individually matched for age, sex, and height. Statistical design: All statistical analyses will be performed using R statistical software version 4.1.1 (R Project for Statistical Computing) within RStudio statistical software version 1.4.1717 (RStudio), and a two-tailed p\<0.05 will be considered statistically significant. Inspection of normality and variance homogeneity will be done by creating qq-plots and histogram. Regulatory considerations: This study will be submitted for approval by Regional Ethical Committee. Perspective: This study will help uncover fundamental aspects of the pathophysiology of COPD.

Chronic Obstructive Pulmonary Disease (COPD) is a serious lung condition that affects millions of people in the United States. Each year, it leads to about 150,000 deaths, nearly 900,000 emergency room visits, and 700,000 hospital stays. When COPD symptoms suddenly get worse-called an exacerbation-it can seriously harm a person's quality of life and often requires emergency care. Treating these flare-ups early can help prevent hospital visits, but right now, there aren't many good ways to make sure people get care quickly. Mobile Integrated Health (MIH) programs send specially trained paramedics, guided remotely by doctors, to care for patients in their homes. This approach could help people with COPD get faster, more effective care without needing to go to the hospital. In this project, the investigators are testing a new program called PEACE (Paramedic Evaluation for Acute COPD Exacerbation). The PEACE program sends community paramedics to patients' homes-when needed and in partnership with their regular doctors-to manage worsening COPD symptoms early. The study team will adapt the PEACE program to meet the needs of adults living at home with moderate to severe COPD, gather feedback from patients and healthcare providers, and run a small pilot study to see if the program is practical and helpful.

This study will evaluate the effect of triple ICS/LAMA/LABA therapy with BGF MDI 320/14.4/9.6 μg on cardiopulmonary outcomes relative to LAMA/LABA therapy with GFF MDI 14.4/9.6 μg in a population with COPD and elevated cardiopulmonary risk.

This study is being conducted to determine the safety of repeat metered cryospray (MCS) treatment in patients with COPD with chronic bronchitis previously treated with MCS.

The goal of the interventional study is to evaluate whether risk-based stratification using the PLCOm2012 model and a machine learning (ML) model can identify patients with chronic obstructive pulmonary disease (COPD) who are at high risk of developing lung cancer and may benefit from low-dose computed tomography (LDCT) screening. The study population includes adults aged 50 years and older with COPD and a history of smoking attending an outpatient clinic. The main question it aims to answer are: \- What is the incidence of histopathologically confirmed lung cancer following risk-based stratification? Participants will: * Undergo lung cancer risk assessment using the PLCOm2012 model and an ML-based model based on clinical and laboratory data * Be referred for LDCT if classified as high-risk * Continue standard care if classified as low-risk * Be followed through electronic health records for up to six years to assess outcomes including lung cancer incidence, adherence to LDCT, time to imaging, healthcare utilization, costs, and safety

Chronic obstructive pulmonary disease (COPD) is a common, progressive, and heterogeneous respiratory disorder. It is associated with substantial morbidity and mortality worldwide, leading to progressive decline in lung function, impaired quality of life, and a significant healthcare burden. REGEND001, made from airway basal stem cells with ability to regenerate lung tissue, is promising to COPD treatment. In this study, a multicenter, randomized, blinded, placebo-parallel-controlled trial is performed to verify the efficacy and safety of REGEND001 in treatment of COPD patients with emphysema.

Pulmonary rehabilitation (PR) is a key non-pharmacological intervention for patients with chronic obstructive pulmonary disease (COPD), yet it remains underutilized, particularly among patients living in peripheral areas due to limited access, travel distance, and logistical barriers. Tele-pulmonary rehabilitation (TPR) has the potential to improve access to care, but its feasibility and effectiveness as a group-based intervention have not been well established. The aim of this study is to evaluate whether a group-based TPR program can improve treatment initiation and adherence compared to usual care, defined as referral to standard PR, among COPD patients living in peripheral areas. In addition, the study will assess the effect of the intervention on COPD exacerbations, symptom burden, quality of life, and patient satisfaction. This is a prospective randomized controlled trial that will enroll patients with COPD who are eligible for PR according to the Israeli health basket criteria and have not participated in PR in the past year. Participants will be randomly assigned to one of two groups: (1) referral to standard PR (control group), or (2) participation in a 12-week, twice-weekly, group-based TPR program delivered remotely via a dedicated application and video sessions (intervention group).

Pulmonary rehabilitation is a key treatment for lung diseases, but many patients struggle to attend sessions due to travel distances, physical limitations, or logistical barriers. The purpose of this study is to evaluate whether a tele-pulmonary rehabilitation (TPR) program can improve the rates of treatment initiation and adherence among patients with chronic lung diseases compared to traditional, center-based pulmonary rehabilitation. Additionally, the study will assess improvements in quality of life, physical symptoms, and safety in both groups. This study will enroll 90 patients from two medical centers in Israel (Tel Aviv and Barzilai). Participants will be randomly assigned to one of two groups: 1. The control group will receive usual care with a referral by a pulmonologist to standard pulmonary rehabilitation at a medical center. 2. The intervention group will participate in a supervised remote tele-rehabilitation program using a dedicated application and remote monitoring.

Breathlessness is a common symptom in people with chronic lung and heart diseases. It can affect daily activities, quality of life, and overall health. Current questionnaires used to assess breathlessness depend on a person's memory of symptoms and may not accurately capture breathlessness during physical activity. This study aims to evaluate whether the one-minute sit-to-stand test (1MSTS), a simple test that involves repeatedly standing up from and sitting down on a chair for one minute, can measure breathlessness during exercise. Adults with chronic obstructive pulmonary disease (COPD), asthma, interstitial lung disease (ILD) or heart failure (HF) will participate. Participants will attend three study visits and complete exercise tests, including the 1MSTS, a six-minute walk test (6MWT), and cardiopulmonary exercise testing (CPET). The study will assess how well breathlessness measured during the 1MSTS test reflects breathlessness during other established exercise tests, and whether the test provides reliable and responsive measurements over time. The results may help establish the 1MSTS as a practical and easy-to-use tool for assessing exertional breathlessness in both clinical practice and research.

This prospective, real-world observational study (T2AIR Study) evaluates the long-term efficacy and safety of six biologics targeting Type 2 inflammation - omalizumab, mepolizumab, benralizumab, dupilumab, tezepelumab, and depemokimab - in patients with chronic airway diseases, including asthma and COPD under routine clinical practice in China. The primary objective is to determine the annualized exacerbation rate (AER) over 12 months of treatment. Secondary objectives include time to first exacerbation, frequency of severe exacerbations, improvements in symptom control and quality of life (using disease-specific questionnaires), lung function (FEV₁, FVC), airway inflammatory biomarkers (FeNO, blood eosinophils, serum IgE), oral corticosteroid (OCS) sparing effect in asthma patients, and treatment persistence. Safety outcomes will assess the incidence, types, and severity of adverse events (AEs) and serious adverse events (SAEs). Exploratory endpoints include high-resolution CT (HRCT)-based imaging markers of airway remodeling and the development of deep learning-based multimodal predictive models integrating clinical, biomarker, and radiomics data to support personalized treatment. Additionally, blood, sputum, and urine samples will be collected for translational research to explore underlying mechanisms and predictors of biologic response. This study aims to generate robust real-world evidence on the effectiveness and safety of Type 2-targeted biologics across the broad spectrum of chronic airway diseases in a diverse Chinese patient population.

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)

Observational, prospective, multicenter cohort study with consecutive inclusion of COPD patients. Eligible patients will be those with severe and very severe COPD according to the GOLD 2024 (Global Initiative for Chronic Obstructive Lung Disease) guidelines being followed at participating hospitals. The severity of COPD is related to the exacerbation rate, which in turn is related to the progression of the disease and the occurrence of complications and death. There is no national data on this subgroup.

Pre-market clinical trial on 81 aldults participants to evidence safety and performance of the non-CE-marked medical device INBENTUS VERSATILE ventilator. The 81 aldult participants are ventilated between 3 and 48 hours with invasive mechanical ventilation (IMV) in assisted/controlled mode and weaning under partial pressure support or volume support, followed by monitoring period until ICU discharge, hospital discharge or 30 days. The study design differentiates between a Validation Cohort (up to 20 participants) for device validation and a Study Cohort (up to 61 participants) for safety and performance confirmation. Serious Adverse Events related to study device and/or its procedure is defined as the primary safety endpoint, whereas technical failure rate is defined as the primary performance endpoint.

This study aims to examine the effects of Active Cycle of Breathing Technique (ACBT) on pulmonary function, sleep quality, depressive symptoms, and dyspnea in patients with Chronic Obstructive Pulmonary Disease. A block-randomized crossover trial will be conducted at the pulmonology outpatient clinic of a regional teaching hospital in eastern Taiwan. Participants aged 40-90 years with physician-diagnosed COPD (post-bronchodilator FEV₁/FVC \< 70%) will be randomly allocated into two groups. The total observation period is 16 weeks with 5 data collection time points: T0 (baseline), T1 (Week 4), T2 (Week 8), T3 (Week 12), and T4 (Week 16). Each intervention period lasts 8 weeks. Primary outcomes are dyspnea (mMRC) and COPD symptom burden (CAT). Secondary outcomes include pulmonary function (FEV₁, FVC), sleep quality (PSQI), and depressive symptoms (DASS-21).

Multi-site, randomized controlled trial to determine whether patients who report NO symptomatic benefit with their maintenance hand-held inhaler(s), benefit upon switching to nebulized therapy using comparable classes of medications.

This is a phase 1, single-dose, 2-period crossover study in healthy volunteers to compare the systemic pharmacokinetic (PK) profile of inhaled AERO-002 versus inhaled active comparator product.

Airway disease, such as chronic obstructive pulmonary disease (COPD), is usually diagnosed through breathing tests like spirometry. However, it requires people to blow forcefully into a machine several times which can be uncomfortable and difficult for some patients. This study is looking at whether newer technologies and other breathing tests can help diagnose COPD as accurately as standard testing. We will compare these tests in both hospital and community settings. We are interested in understanding how practical and cost-effective these tests are, including how easy they are to use and how comfortable they are for patients to perform.

The goal of this study is to evaluate the impact of implementing an AI-enabled clinical workflow tool (Viz COPD) on respiratory specialist follow up and clinical outcomes after an acute exacerbation.

Chronic obstructive pulmonary disease (COPD) is often complicated by acute exacerbations, which lead to functional impairments, increased dyspnea, and a rapid decline in lung function. During an exacerbation, impaired pulmonary gas exchange, systemic inflammation, and increased work of breathing significantly alter oxygen availability and metabolic demand in skeletal muscles. The aim of this study is to evaluate and compare respiratory and peripheral muscle oxygenation in patients with acute exacerbation of COPD (AECOPD) and patients with clinically stable COPD. By examining these physiological changes, the study seeks to determine the impact of exacerbations on muscle function and oxygenation efficiency

The STRIDE Registry will evaluate the real-world effectiveness and safety of dupilumab in participants with COPD. The primary objective is to describe characteristics of participants newly initiated with dupilumab for COPD. Secondary objectives are to determine whether treatment with dupilumab reduces moderate and/or severe COPD exacerbations; to determine the impact of treatment on lung function in COPD participants; to determine whether treatment with dupilumab improves the quality of life in COPD participants; and to describe safety of dupilumab among COPD participants. The external control cohort will include participants with COPD from the National Patient-Centered Clinical Research Network (PCORnet) consortium who are not being treated with dupilumab. In addition, chest images will be collected and banked for future research projects and consented participants will perform home spirometry.

This prospective, monocenter pilot study will investigate the relationship between indoor environmental quality (including air quality, lighting, noise, and thermal conditions), wearable-derived health insights, and patient-reported symptoms in patients recovering at home after hospitalization for an acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Participants will undergo continuous monitoring of indoor environmental conditions and health parameters using a Garmin Venu 4 smartwatch, together with validated questionnaires assessing COPD symptoms, sleep quality, and daytime sleepiness during one month. The study will assess the feasibility and potential added value of high-resolution home monitoring and explore whether environmental and wearable-derived measures are associated with symptom burden and early signs of clinical deterioration following hospital discharge. The investigators hypothesize that continuous in-home monitoring of indoor environmental quality is feasible and provides clinically relevant insights into symptom burden in recently hospitalized COPD patients. The primary objective is to determine the correlation between indoor environmental quality (IEQ) variables and symptom burden in COPD patients following hospitalization for AECOPD.

The goal of this clinical trial is to evaluate whether inhaled Treprostinil (Tyvaso) can improve oxygen delivery and blood flow in the lungs in adults (age ≥40) with chronic obstructive pulmonary disease (COPD) and hypoxemia who have less severe reduction in lung blood volume (diffusing capacity of the lungs for carbon monoxide \[DLCO\] ≥45%). The main questions it aims to answer are: 1. Does inhaled Treprostinil increase pulmonary capillary blood volume in ventilated lung regions, as measured by hyperpolarized xenon-129 magnetic resonance imaging (HP129Xe MRI)? 2. Does inhaled Treprostinil improve oxygen delivery (measured as red blood cell \[RBC\] chemical shift) and maintain or only slightly change pulmonary vascular resistance (measured by RBC oscillation amplitude)? 3. Can pre-treatment MRI parameters (RBC transfer and RBC oscillation amplitude) predict who will respond to inhaled Treprostinil? Participants will: * Use the Tyvaso nebulizer (inhaled Treprostinil) 4 times daily for 4 weeks, starting at 3 breaths per session and increasing to a maximum of 6 breaths per session as tolerated. * Undergo HP129Xe MRI before and after treatment to assess regional lung function and oxygen exchange. * Complete pulmonary function tests (PFTs), 6-minute walk tests (6MWT), and echocardiograms at the beginning and end of the study. * Be monitored for adverse events, with a phone check-in midway through and after the treatment period.
