Recruiting studies
- NCT05437198Recruiting
Breath sample study comparing lung bacteria in and out of COPD
This study looks at the germs in exhaled (breathed-out) air to compare people with COPD to people without COPD. It may help researchers better understand lung differences and what could drive COPD.
CréteilAges 18–70 - NCT05399056Recruiting
Peer support and storytelling to help COPD lung rehab
This study aims to improve how well people with COPD can take part in pulmonary rehabilitation by using peer coaching and short storytelling videos. If you recently had a COPD flare and are being referred to lung rehab, this may offer extra support to help you complete the program.
Springfield, MassachusettsAges 40 years+ - NCT05265299RecruitingPhase 3
Testing the right aspirin dose for COPD symptoms
This Phase 3 trial studies which aspirin dose works best in people with COPD, with the goal of improving disease control. You may be asked to take aspirin and be monitored for safety, especially bleeding risk and heart/brain history.
Baltimore, MarylandAges 40–80 - NCT05297279Recruiting
Omega-3 diet program for people with COPD
This trial tests whether increasing omega-3 (from diet and/or supplements) helps people with COPD. It enrolls people with low omega-3 intake and asks them to follow a specific dietary plan during the study.
Baltimore, MarylandAges 40 years+ - NCT05237505RecruitingPhase 2
Sleep apnea plus COPD study to check heart and breathing effects
This Phase 2 study looks at the cardiovascular (heart/blood vessel) effects of having both sleep apnea and COPD. It may help doctors better understand who is at risk and how to manage these breathing problems together.
La Jolla, CaliforniaAges 40–79 - NCT05196698Recruiting
Home high-flow oxygen after COPD hospital flare
This study tests whether using a special oxygen device at home helps prevent another acute COPD flare after you’ve been hospitalized. It’s mainly for people with severe breathing problems who may need oxygen support long-term.
RouenAges 18–85 - NCT05061368RecruitingPhase 2
Sildenafil by mouth to improve breathing in COPD
This Phase 2 trial tests whether sildenafil tablets can improve exercise ability, shortness of breath, and heart-lung function in people with COPD. It also compares against people without COPD to better understand how sildenafil affects breathing tests.
Edmonton, AlbertaAges 40–80 - NCT05008081Recruiting
Study for COPD flare-ups given standard rescue medicines
This study looks at people hospitalized for a COPD flare-up (“exacerbation”). It may help improve how flare-ups are treated because participants need to receive the usual rescue medicines like steroids and/or antibiotics and then follow a study plan.
LinzAges 18 years+ - NCT04849806Recruiting
Testing whether heart nerve signals predict COPD symptoms
This study looks at “sympathetic nerve activity” (signals from the nervous system that affect the heart) in adults with chronic obstructive pulmonary disease (COPD). The goal is to see whether these measurements can help predict what happens to people with COPD.
AachenAges 18 years+ - NCT04722835Recruiting
Study lung immune cells in people at risk for COPD
This study looks at different lung immune cell patterns and how they work in smokers who are not yet diagnosed with COPD or asthma. It may help researchers understand why some people are more likely to develop COPD, which could guide future prevention or early treatments.
San Francisco, CaliforniaAges 40–75 - NCT04427826RecruitingPhase 1/Phase 2
Morphine to prevent early NIV failure in COPD flare-ups
This trial studies whether morphine can help people with a COPD flare-up avoid “non-invasive ventilation” (breathing support through a mask) failing early. The goal is to reduce how often people need escalation of care soon after starting NIV.
Grenoble, Isère, Auvergne-Rhône-AlpesAges 18 years+ - NCT04339270RecruitingPhase 4
Testing azithromycin in chronic lung disease with frequent flare-ups
This Phase 4 study tests whether a long course of azithromycin can reduce flare-ups in people with chronic obstructive pulmonary disease (COPD) who have had recent exacerbations. It also looks at mucus properties and how flare-ups happen.
BordeauxAges 40–85 - NCT04179981Recruiting
CPAP treatment effects in older COPD and sleep apnea patients
This study looks at whether using positive airway pressure (often called CPAP) improves health outcomes in older adults who have both COPD and obstructive sleep apnea. It may help find ways to reduce symptoms and complications from “overlap” breathing problems.
Detroit, MichiganAges 60 years+ - NCT04236726Recruiting
Quality of life study for people with chronic breathing failure
This study looks at how chronic respiratory failure affects day-to-day quality of life. It enrolls people who use breathing support at home or in care, and may help clinicians understand what support works best for patients’ daily living.
LondonAges 18 years+ - NCT03799354Recruiting
Strength training study for people with COPD
This trial tests whether a maximal strength training program can help people with COPD who are stable. It is looking at people with moderate-to-severe airflow limitation and excludes several other lung and health problems.
Lumezzane, BresciaAges 50–80 - NCT03450603Recruiting
Predicting COPD flare-up risk in adults
This study looks at factors that can predict when chronic obstructive pulmonary disease (COPD) will flare up. It may help doctors identify people at higher risk sooner and tailor care to prevent flare-ups.
ShanghaiAges 40 years+ - NCT03044847Enrolling by invitation
Long-term study of COPD in adults in China
This study follows people with COPD (chronic lung disease) over many years to better understand the condition. It may help doctors learn what factors predict worsening over time.
Beijing, Beijing MunicipalityAges 40–75 - NCT02966665RecruitingPhase 1
Testing blood vessel function in people of different health conditions
This early study measures how well your blood vessels work using tests that may include MRI. It compares healthy people with people who have conditions like COPD, pulmonary arterial hypertension, heart failure, or high blood pressure, to better understand “vascular function” in health and disease.
Salt Lake City, UtahAges 18 years+ - NCT01460264Enrolling by invitation
A heart-and-lung health study following adults over time
This study follows adults with heart-and-lung health information over time to understand how these conditions change. It may help researchers find patterns that could guide better care in the future.
LundAges 45–75 - NCT00307281Recruiting
Emphysema and COPD patient registry with sample storage
This study enrolls people who have emphysema/COPD into a research registry and collects health information and biological samples. It may help researchers understand the disease better and improve future treatments.
Pittsburgh, PennsylvaniaAges 21 years+ - NCT06409624Recruiting
Biomarkers and kidney decline in pulmonary hypertension
This study looks at how certain blood markers (biomarkers) relate to kidney function decline in people with pulmonary hypertension. Participants will have blood and urine tests, and their kidney function will be tracked over time.
Bad Nauheim, HesseAges 18 years+ - NCT04911491Recruiting
Breathing muscle training for people with kidney disease
This study tests whether training your breathing muscles can improve health in people with chronic kidney disease (stage 3–4). It may help how your body handles daily activity and circulation-related measurements, compared with usual care.
Aurora, ColoradoAges 50 years+ - NCT06579612Recruiting
Personalized exercise support for chronic lung disease
This trial tests whether one-on-one guidance from a sports-health specialist can improve your well-being if you have a chronic lung condition like asthma, COPD, or sleep apnea and are already taking part in a lung rehabilitation program.
BrestAges 18–80 - NCT06523608Recruiting
Predicting liver problems in advanced chronic liver disease
This study looks at people with advanced chronic liver disease to find ways to predict when they might get worse or develop liver cancer. Researchers hope to use this information to prevent complications and improve care.
