COPD clinical trials — recruiting now

Establish the largest possible real-life cohort collecting long-term follow-up of a maximum number of CML patients in order to carry out observational studies: epidemiological, identification of subgroups according to their response to treatment, evaluation of new molecules in real life, therapeutic discontinuations, impact of the evolution of recommendations, etc.

The combined effects of transcutaneous electrical diaphragmatic stimulation (TEDS) and active cycle of breathing techniques (ACBTs) in patients with chronic obstructive pulmonary disease (COPD) conducted as a randomized controlled trial at Gulab Devi Hospital, the study involved 50 participants aged 40 to 60 with mild to moderate COPD. Participants were divided into two groups, one receiving both TEDS and ACBT, and the other receiving only ACBT. Over 12 weeks, improvements in lung function, oxygen saturation, exercise capacity, and quality of life were measured using spirometry, pulse oximetry, the 6-minute walk test, and the St. George's Respiratory Questionnaire. Both groups showed significant improvement, but the group receiving ACBT alone showed a slightly higher mean rank in some outcomes. The study concludes that while both interventions are beneficial, ACBT alone may offer more consistent improvements. It recommends including respiratory muscle assessments and combining interventions with education and exercise in future research.

The goal of this observational study is to learn about the effects of a 9-week dietician-guided program modified from the National Diabetic Prevention Program (modified DPP-diet) in people with spinal cord injury on body composition and insulin sensitivity. The main question it aims to answer is: Does 9 week modified DPP-diet reduce body fat percentage and insulin resistance? Participants will: Have 9 weeks of Telehealth visit with dietician certified in providing DPP. Visit the laboratory before, immediately and 9 weeks after completion of the modified DPP-diet. Share with the researcher on the perceived benefit and obstacles in implementing the modified DPP-diet as part of their daily activities.

The aim of this interventional, cross-sectional and pathophysiological experimental study is to evaluate the potential of a patient's induced pluripotent stem (iPS) cells, used prior to the re-differentiation stage, to enable ex vivo repair of the injured epithelium in patients with chronic obstructive pulmonary disease (COPD), smokers without COPD and non-smoking controls. The main questions it aims to answer are: * to evaluate the repair capacity of bronchial epithelium in COPD subjects, using a model of bronchial epithelium reconstituted in air/liquid interface culture and the iPS model. * epithelia repair capacities in normal or aberrant situations, as well as the time required for this repair, and to determine the involvement of grafted iPS cells in epithelia repair in cultured control subjects, smokers without COPD and COPD patients. Researchers will compare 3 groups of participants (COPD patients, smokers without COPD and non-smokers without COPD) for epithelial repair efficacy between non-grafted ALI cultures and ALI cultures grafted with iPS cells, in order to assess their contribution to epithelial repair. Participants will undergo a bronchial fibroscopy (for clinical indications) with two additional biopsies specific to the study. This research could lead to breakthroughs in cell-based therapies for COPD, with long-term implications for epigenetic treatments and in vivo applications.

The CATALINA study is a prospective cohort study embedded within CICERO (Collaboration In COPD ExaceRbatiOns, a European Respiratory Society supported Clinical Research Collaboration), designed to collect standardised, longitudinal clinical data and biological samples in 20 centres across Europe and beyond.

Chronic obstructive pulmonary disease (COPD) is a major chronic respiratory condition with high prevalence of multimorbidity. COPD and comorbidities interact dynamically, contributing to symptom fluctuation, acute exacerbations, hospitalization, and long-term disease progression. The IMPACT COPD Cohort (China) is a multicenter prospective observational cohort designed to establish a real-world evidence base for integrative Chinese-Western medicine management of COPD with comorbidities. The cohort integrates conventional clinical assessments (symptoms, questionnaires, spirometry, imaging, and biomarkers) with continuous multisensor digital monitoring (e.g., heart rate, blood pressure, activity, sleep patterns, and other physiological and behavioral measures) and digital Traditional Chinese Medicine (TCM) phenotyping (e.g., tongue, pulse, and facial diagnostics). The study aims to characterize risk profiles of high-risk populations and patients with confirmed comorbidities, develop and validate prediction models for comorbidity risk and acute exacerbation events, and support evidence generation for long-term management strategies with early screening and risk warning capabilities across hospital, community, and home settings.

Background: People with blood cancers often receive blood or bone marrow transplants. But even with these treatments, the risk of relapse is high. Researchers want to see if giving the transplant recipient an infusion of lymphocytes (a type of white blood cell) from their transplant donor early after the transplant can reduce that risk. Objective: To learn if giving donor lymphocytes early after a transplant will help reduce the risk of relapse for people with certain blood cancers. Eligibility: Adults aged 18-65 with high-risk leukemia, lymphoma, myelodysplastic syndrome, or multiple myeloma that does not respond well to standard treatments and/or has a high risk of relapse. Healthy potential bone marrow and lymphocyte donor relatives aged 12 and older are also needed. Design: Participants will be screened with: Physical exam Blood and urine tests Spinal tap Eye exam Dental exam Heart and lung tests Imaging scans. A radioactive substance may be injected in their arm if a PET scan is needed. Bone marrow aspiration and biopsy Some screening tests will be repeated during the study. Participants will stay at the NIH hospital for about 4 weeks. They will receive a central venous catheter. They will get chemotherapy and other drugs starting 6 days before transplant. Then they will have their transplant. They will receive donor white blood cells 7 days later. They will give blood, bone marrow, urine, and stool samples for research. They must stay near NIH for at least 100 days after transplant. Participants will have periodic follow-up visits for 5 years. Healthy donors will have 2-3 visits. They will give blood, bone marrow, white blood cells, and stool samples for research. Participation will last for 5 years....

Obstructive sleep apnea (OSA) and Chronic Obstructive Pulmonary Disease (COPD) are highly prevalent chronic respiratory diseases in the Veteran population. OSA co-occurring with COPD, known as Overlap Syndrome (OVS), is a complex chronic medical condition associated with grave consequences. OVS is highly prevalent in Veterans. Veterans with OVS may be at increased risk for cognitive deficits, poor sleep quality as well as a reduced quality of life (QoL). The overall objective is to study the effects of positive airway pressure therapy on clinical outcomes in patients with OVS.

We aim to clarify the relationship between sleep hygiene and the onset of sarcopenia or cognitive dysfunction using sleep time, arousal, and sleep quality as indicators in COPD or IPF patients, and clarify the effects of sleep hygiene on disease progression and life prognosis.

Laparoscopic cholecystectomy, while less painful compared to conventional methods, is still a surgery that can cause significant pain for patients. Preventing postoperative pain is crucial for reducing respiratory complications, shortening hospital stays, and increasing patient satisfaction. Interfascial plane blocks have been widely used for postoperative analgesia in recent years worldwide. The External Oblique Intercostal Plane Block is one of the interfascial plane blocks used in abdominal surgeries. In our study, we aimed to compare the postoperative pain scores of patients who underwent laparoscopic cholecystectomy under general anesthesia, specifically between those who received the external oblique intercostal plane block and those who had trocar entry site infiltration.

This cross-sectional observational study aims to assess the diaphragmatic morphofunction and respiratory drive characteristics among patients with obstructive sleep apnea (OSA), chronic obstructive pulmonary disease (COPD), overlap syndrome (OS), and healthy controls. Using ultrasound imaging and surface diaphragm electromyography (EMGdi), the study will explore group differences in diaphragmatic morphology, function, and respiratory drive indicators, and evaluate their clinical significance in disease differentiation and severity assessment.

Rationale: Bronchoscopic lung volume reduction using endobronchial valves (EBV) has emerged as a viable treatment option for eligible patients with severe emphysema. In all studies conducted so far, exercise capacity has only been measured using the 6-minute walk distance test (6MWT). It is known that patients with COPD frequently experience problems during ADL, which can lead to avoidance of or care dependency for performing certain tasks and have a significant social impact on their lives. Patients report that it is easier to perform ADLs after EBV treatment. Previously it was found that it was easier for patient to perform these activities after the EBV treatment. However, the physiological load during these ADLs has never been investigated before. Potentially, EBV treatment could improve the metabolic load and consequently symptom perception, thus enhancing the execution of ADLs, which is an important patient-centred outcome. However, this has not been investigated so far. Objective: To investigate the change in exercise physiology during daily activities after EBV treatment. Study design: Observational study in which the study population will be asked to perform some additional test during regular visits for the bronchoscopic lung volume reduction treatment with valves. Study population: Patients with emphysema who are scheduled for a bronchoscopic lung volume reduction treatment using endobronchial valves. Intervention: Not applicable Main study parameters: The change in task-related oxygen uptake measured with a mobile oxygen device during activities of daily life 6 months after EBV treatment.

This study evaluates whether adding a spacer device to triple inhaled therapy (ICS/LABA/LAMA via pMDI) can reduce acute exacerbations in elderly patients (≥65 years) with stable chronic airway diseases (COPD or asthma) who are classified as high-risk based on GOLD or GINA guidelines. High-risk is defined as ≥1 hospitalization or ≥2 moderate exacerbations in the past 12 months. Despite receiving maximum inhaled treatment, these patients often have poor inhaler technique due to age-related limitations. A spacer may improve drug delivery, adherence, and reduce local side effects. In this multicenter, open-label, randomized controlled trial, 380 participants will be assigned to standard therapy with or without a valved face-mask spacer. The primary outcome is the 3-month incidence of moderate-to-severe exacerbations. Secondary outcomes include lung function, adherence, inhalation technique, side effects, and patient satisfaction.

Chronic obstructive pulmonary disease (COPD) is an irreversible disorder characterized by persistent airflow limitation and increased lung compliance. It leads to dyspnea, skeletal muscle dysfunction, impaired functional capacity, and reduced quality of life. Physical inactivity is considered a major contributor to symptom deterioration, the development of a vicious cycle, and ultimately increased mortality. According to the American College of Sports Medicine (ACSM), the American Thoracic Society (ATS), and the American Association of Cardiovascular and Pulmonary Rehabilitation (AACVPR), pulmonary rehabilitation should include aerobic and resistance exercise for at least 20 minutes per session, performed three to five times per week for a minimum of 12 weeks. Exercise intensity should be progressively increased to exceed 60% of peak oxygen uptake (VO₂peak), and patients are encouraged to maintain long-term exercise habits. However, there is still no consensus regarding the optimal initial intensity, progression strategy, and exercise duration. Previous studies have demonstrated that whole-body vibration (WBV) can improve lower extremity muscle strength, functional capacity, and quality of life in patients with COPD. However, its effects on lung function and the optimal training dose remain unclear. In addition, COPD also affects respiratory muscles, upper extremity strength and flexibility, as well as cardiac autonomic function. Therefore, the aim of this study is to investigate the effects of different WBV frequencies on lung function, respiratory muscle function, upper extremity strength and flexibility, and cardiac autonomic function, in order to determine the optimal training dose.

This Study is multicenter, non-interventional, ambispective registry to evaluate the demographic and clinical characteristics, therapeutic approaches and outcomes in COPD outpatients with frequent exacerbations in Moscow

Cognitive dysfunction in the aging Veteran population is a growing health concern in the Veterans Health System. It is not known whether OSA coexisting with COPD will enhance the risk for cognitive dysfunction. The investigators sought to investigate whether these two highly prevalent diseases, that often co-exist as the 'Overlap Syndrome', combine to enhance cognitive impairment in the elderly Veteran population. Thus, the investigators will study whether elderly patients with Overlap syndrome have increased cognitive deficits compared with OSA or COPD alone. Additionally, treatment of OSA with positive airway pressure (PAP) has been shown to improve neurocognitive function in moderate-to-severe OSA while cognitive decline in COPD may be reversible through treatment with long-term oxygen therapy. The investigators will also study whether treatment with positive airway pressure (PAP) and supplemental oxygen vs PAP alone will improve cognitive function and improve quality of life of elderly Veterans.

This prospective observational study evaluates the association between psychiatric status, GvHD-related symptom severity, and health-related quality of life in patients with graft-versus-host disease. Standardized and validated assessment tools, including the Lee Symptom Scale, will be used to collect psychiatric, clinical, and demographic data.

The project will be pursued in our respiratory, autonomic nervous system physiology laboratory (Respiratory, autonomic nervous system physiology laboratory, Department of Pneumology and Intensive Care Medicine, RWTH Aachen University Hospital; Head of Department: Professor Michael Dreher). Overactivity of the sympathetic nerve activity (SNA) axis with "centrally" increased heart rate and peripheral vasoconstriction is a known phenomenon in patients with systolic heart failure (HF) and has recently been described in patients with primary lung disease as seen in chronic obstructive pulmonary disease (COPD). However, systematic analyses on this clinically relevant topic are currently lacking. Thus, using a comprehensive, multimodal approach and state-of-the-art technology, this research project is designed to determine the extent and nature of increased SNA in COPD (AIM 1) and evaluate the underlying mechanisms (AIM 2). The project will address the following hypotheses: 1. In COPD, concomitant obstructive sleep apnea is independently associated with increased SNA. 2. Precapillary pulmonary hypertension (PH), inspiratory muscle dysfunction and systemic inflammation describe a COPD phenotype characterised by increased SNA with a different subtype.

This study will look at people with COPD who use a home breathing machine called non-invasive ventilation (NIV). NIV machines collect information about your breathing, such as air flow, pressure, and mask leaks. Researchers want to use a computer program, called artificial intelligence (AI), to study this information. The goal is to find early signs that your breathing may be getting worse. People with COPD who already use NIV at home may join this study. The study does not change your treatment. It only uses the breathing data already recorded by your NIV machine. The computer program will look for patterns in the data. These patterns may help doctors: Notice early warning signs of a COPD flare-up Find problems with how you and the machine work together Improve the way NIV is monitored at home The main goal is to create a tool that helps patients and doctors manage home NIV more easily and more safely.

Chronic Obstructive Pulmonary Disease (COPD) is a global health concern, associated with structural lung abnormalities causing persistent airflow limitation (AL) and often result from cigarette smoking. In Turkey, COPD was ranked the third among the mortality causes and the eighth among disability causes, with 9.1% to 19.1% prevalence rate. In the Middle East and North Africa (MENA) region, an increase of 30.6% in age-standardized point prevalence occurred between 1990 and 2019, with an estimated 10.7 million COPD cases. Similarly, in the sub-Saharan Africa region, the highest COPD prevalence rate of 24.8% was observed in South Africa. And in Kenya, East Africa, the pooled point estimate prevalence of COPD was 11.3%. The prevalence of COPD varies substantially between countries, but comparing numbers is challenging because they are recorded in different units and during different periods. Patients with COPD are more likely to develop cardiovascular disease (CVD). For instance, COPD has been shown to increase the risk of acute myocardial infarction by 40% and stroke by 50%. Likewise, COPD patients with CVD have a considerably higher risk of COPD exacerbations than those without CVD. COPD and CVD have been linked to a worse prognosis primarily related to increased systemic inflammation; the presence of a concomitant disease with COPD leads to reduced quality of life, increased hospitalizations, and worse survival. For instance, every increase of 70 cL/s in forced expiratory volume in 1 second (FEV1) reduces mortality risk by 28%-35% from cardiovascular disease and 68%-72% from respiratory disease. Besides that, smoking has been shown to increase the risk of myocardial infarction (MI) and heart failure (HF) twofold, cigarette smoking toxins promote inflammation systemically, which may result in emphysema and atherosclerosis. Nevertheless, chronic inhalation of irritants, including biomass fuel smoke and air pollutants, produces an innate immune response and a later activation of adaptive immunity that might further amplify inflammation. Similarly, age-related elastin degradation may increase the risk of emphysema and arterial hypertension. On the contrary, physical activity is associated with improved lung function and a lower resting heart rate (RHR); consequently, COPD and CVD are more prevalent in sedentary populations. Observational studies suggest that decreasing the progression of COPD may assist in preventing cardiovascular morbidity and mortality, which is related to more severe respiratory symptoms.
