Exercise and how it affects sleep apnea severity
This study looks at whether regular physical activity can make obstructive sleep apnea (OSA) less severe. It focuses on people who are not yet receiving OSA treatment and checks changes in severity over time.
GrenobleAges 18–80 - NCT04624373Recruiting
Test tumor DNA from breath biopsy samples
This study checks tiny pieces of DNA from a sample taken during a breathing-tube biopsy (EBUS-TBNA) to better identify certain lung cancer changes. It may help doctors learn more about the type of lung cancer and, in some cases, why targeted treatments stop working.
ToulouseAges 18–65 - NCT04624490RecruitingPhase 1
Lung function MRI using a special gas in volunteers
This Phase 1 study tests a lung scan that uses a special gas and MRI to measure how well your lungs work. It includes healthy volunteers and people with lung disease to see how well the scan works and how safe it is.
Kansas City, KansasAges 3 years+ - NCT04630496Recruiting
Walk Test Before Lung Surgery for Older Adults
This study is looking at a “walk and movement” challenge for older adults preparing for thoracic (chest) surgery. It may help the team understand mobility and support safer care before surgery.
Boston, MassachusettsAges 65 years+ - NCT04630535Recruiting
Using brief arm treatment before bypass surgery
This trial studies whether a simple, remote “arm treatment” given before scheduled aorto-bifemoral bypass surgery can help protect blood flow during surgery. If you fit the surgery plan and don’t have certain excluded conditions, the study may offer an added protective approach.
Brno, Czech RepublicAges 18 years+ - NCT04631770Recruiting
Mediastinal node removal versus sparing nodes for early lung nodule
This trial compares two surgical approaches for people with a single small, noncancer-looking lung nodule (a GGN) that is diagnosed as very early lung cancer. It aims to see whether removing mediastinal lymph nodes—or leaving them alone—can lead to better outcomes with less harm.
Tianjin, Tianjin MunicipalityAges Any age - NCT04639791Recruiting
Managing asthma in adults on GINA steps 4 to 5
This study looks at how well guideline-based asthma treatment works for adults with more severe asthma (GINA steps 4 and 5). It may help improve real-world care for people whose asthma needs stronger medications to stay controlled.
ShatinAges 18 years+ - NCT04642352Recruiting
Nerve block injections for long-lasting nerve cough
This trial studies an office-based injection to calm a specific nerve in the neck to treat chronic cough that seems to come from nerve irritation (“neurogenic/sensory neuropathic” cough). It may help people whose cough has lasted at least 8 weeks and continues despite standard treatments for common cough causes.
Birmingham, AlabamaAges 18 years+ - NCT04644952Recruiting
Study of robotic lung segment surgery outcomes
This study looks at people who had a lung surgery called a segmentectomy with robotic assistance in the past. It aims to understand how these surgeries are done over time and what outcomes result for patients.
Houston, TexasAges Any age - NCT04645511Recruiting
Balloon treatment for long-term or repeat maxillary sinusitis
This study tests whether balloon sinuplasty works better or more efficiently for people with long-lasting or repeatedly returning inflammation in the maxillary sinuses (side sinuses near your cheeks). It focuses on people who did not improve with the usual nose spray (topical steroid) or who meet specific “recurrent” episode patterns.
TampereAges 18–69 - NCT04647656Recruiting
Hyperbaric oxygen for lingering post-COVID brain fog
This study tests whether breathing pure oxygen in a pressurized chamber (hyperbaric oxygen therapy) can improve long-lasting post-COVID problems with thinking and memory. It may help if your brain symptoms have lasted at least 3 months and affect your daily life.
ẔerifinAges 18 years+ - NCT04647630Recruiting
Check which pneumococcus types cause pneumonia
This trial looks at which “pneumococcus” (a common germ) types are causing pneumonia in people admitted to the hospital. It uses a urine test kit to see how often different pneumococcal types are involved, which may help future treatment choices.
ShatinAges 18 years+ - NCT04650919Recruiting
Rehabilitation graft after larynx removal for upper airway cancer
This trial tests a special “rehabilitation graft” used after total laryngectomy (complete larynx removal) for upper airway cancer. The goal is to improve recovery and function after surgery by using a graft designed to support healing and rehabilitation.
StrasbourgAges 18 years+ - NCT04654364Recruiting
Lung cancer registry that tracks patient information
This trial is a registry that collects information from people with certain types and stages of lung cancer. It helps researchers understand how these cancers are managed in real life, which can guide better future care.
Salzburg, State of SalzburgAges 18 years+ - NCT04654650Recruiting
Study of adults with pulmonary hypertension for long-term data
This study follows adults with pulmonary hypertension over the long term and collects information (and possibly samples) to better understand how the condition changes over time. It may help researchers learn what factors affect outcomes, which can improve care in the future.
Hamburg, Free and Hanseatic City of HamburgAges 18 years+ - NCT04657042Recruiting
4D MRI scans to guide lung or liver cancer radiation
This trial tests whether special “4D” MRI scans can improve precision radiation planning for people with lung or liver cancer. You may get MRI scan data to better account for tumor movement, alongside your usual radiation treatment.
Charlottesville, VirginiaAges 18–82 - NCT04658290Recruiting
Sleep apnea screening and memory test study
This study looks at how common obstructive sleep apnea is and whether it’s linked to thinking and memory problems. It may help clarify which people with sleep apnea might be more likely to have cognitive difficulties.
Hong Kong, Please SelectAges 40–74 - NCT04659291Recruiting
Studying people in Hong Kong who may have sleep apnea
This study looks at people who may have obstructive sleep apnea, a breathing problem during sleep. It aims to better understand the condition in Hong Kong and what to do next for diagnosis or care.
Hong Kong, Please SelectAges 18 years+ - 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+ - NCT04665674Recruiting
Study of adults with pulmonary Langerhans cell histiocytosis
This study follows adults with a specific lung condition to better understand how it behaves over time. If you have the right diagnosis, joining could help researchers learn what to expect and how to manage it.

Studying breathing effort in people with COVID-19 breathing failure
This study looks at how hard people with COVID-19 are working to breathe when they have serious breathing trouble but are not yet fully on a breathing machine. The results may help doctors better understand breathing support needs and improve care.
ModenaAges 18–80 - NCT04675268Recruiting
Testing nighttime oxygen patterns in suspected sleep apnea
This study looks at how oxygen levels change during the night in people who might have obstructive sleep apnea (OSA). It may help doctors better understand breathing problems during sleep and improve how OSA is evaluated.
LeuvenAges 18 years+ - NCT04675476Recruiting
Phone and clinic support to help with lung screening
This study tests a patient-and-provider program to improve lung cancer screening for people who have missed appointments or did not follow through. It may help you get back on track with lung screening after a longer gap.

SPECT-guided radiation to avoid healthy lung in lung cancer
This study tests a special imaging-guided radiation plan that aims to treat lung cancer while reducing radiation to healthy lung tissue. It may help lower lung side effects while keeping the cancer treatment focused on tumor areas.
