This trial tests a new drug called AZD6793 for people with moderate to very severe COPD. It aims to see if the drug can help improve breathing and reduce flare-ups.
Birmingham, AlabamaAges 40 years+ - 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+ - 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 - NCT04664491Recruiting
Program to reduce COPD flare-ups with standardized care
This study tests whether a structured care program for COPD can lower how often your symptoms flare up. It may help by improving everyday management and preventing future worsening.
Beijing, Beijing MunicipalityAges 40 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+ - NCT04986332Recruiting
Program for COPD or heart failure in people with other illnesses
This trial studies a detailed, whole-body program to improve outcomes in people with COPD or heart failure, especially those who also have several other chronic conditions. It may help by improving activity and monitoring health markers over about 24 weeks.
PalermoAges 45–75 - 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 - 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 - NCT05235685Recruiting
Testing muscle fatigue during exercise in COPD and heart failure
This study looks at how tired your muscles get during a controlled cycling exercise test in people who have COPD, and—if applicable—heart failure at the same time. It may help researchers understand exercise limits and how to better support you with these conditions.
Échirolles, Auvergne-Rhône-AlpesAges 18 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 - NCT05553223Recruiting
Very small activity doses for COPD symptoms
This study tests whether “micro-doses” of physical activity (short, small amounts) can help people with COPD. It aims to see if these small activity bursts are safe and beneficial for people who have stable COPD.
Kelowna, British ColumbiaAges Any age - NCT05572632Recruiting
COPD wellness rehab program for safety-net patients
This trial studies a COPD (chronic lung disease) wellness and rehabilitation program for people who get care through the safety-net health system. It may help improve day-to-day outcomes by supporting safer exercise and better COPD management.
San Francisco, CaliforniaAges 40–90 - NCT05704881Recruiting
Using breath CO2 levels to judge COPD flare severity in ER
This study measures an easy breathing signal called end-tidal carbon dioxide (a CO2 reading from your exhaled breath) to help judge how severe a COPD flare is. It may help doctors decide how closely you need monitoring and treatment during emergency care.
Grenoble, IsèreAges 18 years+ - NCT05717192Recruiting
Bronchoscopy treatment to shrink severe emphysema using heat
This trial studies a bronchoscopy procedure that uses heat (thermoablation) to reduce over-inflated lung tissue in people with severe emphysema. If you qualify, it aims to improve breathing and walking ability after trying standard treatments first.
BerlinAges 40–75 - NCT05785026Recruiting
Menthol to reduce breathlessness in COPD and healthy adults
This trial tests whether menthol helps with breathlessness (dyspnea) during exercise. You may be asked to do breathing and exercise tests, and to use menthol under study supervision to see if symptoms improve.
LeuvenAges 18 years+ - NCT05844462RecruitingPhase 3
Tadalafil for severe lung blood-pressure problems from COPD
This study tests whether tadalafil can improve outcomes for people with severe pulmonary hypertension caused by COPD (chronic lung disease). It compares how you do with tadalafil versus standard care, focusing on breathing symptoms and how well your heart and lungs cope.
Le Kremlin-Bicêtre, FranceAges 18–85 - NCT05896579Recruiting
Study heart function during rest and exercise in COPD
This study measures how well the right side of your heart works when you are resting and when you exercise, in people with chronic obstructive pulmonary disease (COPD). It may help researchers better understand COPD-related heart strain and guide future care.
Aurora, ColoradoAges 40 years+ - NCT05896800Recruiting
Inhaled nitric oxide for moderate to severe COPD symptoms
This study tests whether inhaled nitric oxide gas can improve outcomes in people with moderate-to-severe chronic obstructive pulmonary disease (COPD). It may help reduce breathing problems by targeting how airways and blood vessels respond in the lungs.
Nanjing, JiangsuAges 40–75 - NCT05937854RecruitingPhase 2
Tadalafil to help breathing in COPD with pulmonary hypertension
This Phase 2 study tests whether tadalafil can improve breathlessness in people with COPD and pulmonary hypertension (high blood pressure in the lungs). It may help you breathe more easily if your symptoms are driven by this specific lung circulation problem.
