MilanAges 18–70 - NCT04007380Recruiting
Sleep problems after spinal cord injury study
This study looks at how sleep-disordered breathing (breathing problems during sleep) affects mood, thinking, and behavior after a spinal cord injury. It may help researchers understand the impact of these sleep breathing issues and guide better support for people after injury.
Toronto, OntarioAges 18 years+ - NCT07574879RecruitingPhase 1
H. pylori Treatment Effects on COPD Symptoms
This study tests whether treating a stomach bacteria infection (H. pylori) can improve breathing and lung function in people with COPD. Researchers want to see if eliminating this bacteria helps reduce COPD symptoms.
Zagazig, ElsharkiaAges 40 years+ - NCT06726564RecruitingPhase 1
Study of MT027 for malignant pleural effusion
This trial tests a new drug called MT027 for people with advanced cancer that has spread to the lining around the lungs (pleura) and caused fluid buildup. The drug targets a marker on cancer cells called B7-H3. It may help control the fluid and the cancer.
BeijingAges 18 years+ - NCT07571109RecruitingPhase 3
Weight Loss Medicine for Sleep Apnea on CPAP
This study tests a new injectable medicine (NNC0487-0111) to help people lose weight and improve obstructive sleep apnea (a breathing condition during sleep). You must already be using a CPAP machine (positive airway pressure device) for your sleep apnea.
Gilbert, ArizonaAges 18 years+ - NCT07573150Recruiting
Pupil Measurements to Predict Breathing Problems After Surgery in Children
This study tests whether measuring how a child's pupils (the dark circles in the eyes) respond to light can predict which children might have breathing problems after receiving pain medication during tonsil surgery. The goal is to help doctors catch and prevent serious breathing issues before they happen.
San Francisco, CaliforniaAges 3–17 - NCT07570394Recruiting
Breztri safety study for COPD and asthma patients in Korea
This study collects information on how Breztri (a medicine for COPD and asthma) works in real-life patients who have just started taking it. It helps ensure the medicine is safe and effective for people like you.
ChuncheonAges Any age - NCT07571005RecruitingPhase 3
Testing a New Weight-Loss Medicine for Sleep Apnea
This study tests whether a new injectable medicine called NNC0487-0111 helps people with excess weight and moderate-to-severe obstructive sleep apnea (a condition where breathing stops repeatedly during sleep) lose weight and improve their sleep apnea—without needing a CPAP machine. The goal is to see if better weight loss can reduce sleep apnea symptoms.
San Diego, CaliforniaAges 18 years+ - NCT03667027Recruiting
Study of breathing muscle and lung changes during transplant planning
This trial studies how the diaphragm (your main breathing muscle) and lung/airway tissue behave in people who are being supported until they can get a lung transplant. The results may help doctors better understand breathing failure and improve transplant care.
TorontoAges 18 years+ - NCT04145024Recruiting
Pulmonary hypertension registry and blood sample biobank
This study keeps a health registry and biobank for people diagnosed with pulmonary hypertension using a specific heart test. It helps researchers better understand the condition and may improve future care.
GiessenAges Any age - NCT05027035Recruiting
Compare diaphragm surgery versus breathing machine support
This trial is studying whether surgery, instead of using a breathing machine, works better for people with one-sided diaphragm paralysis. It aims to improve breathing comfort and function in the right patients.
GroningenAges 18 years+ - NCT05349227Recruiting
After-cancer digital coaching and wearable tracking outcomes study
This study tests a digital health coaching program (using phone/tablet check-ins and wearable data) to understand health and quality-of-life outcomes after cancer treatment. It may help you learn healthy habits and track progress over time.
Gainesville, FloridaAges 18 years+ - NCT05473689Recruiting
Sleep study in early spinal cord injury
This study looks at how sleep quality affects movement problems after a new spinal cord injury. Researchers hope to identify sleep targets that could improve motor function during recovery.
Toronto, OntarioAges 18 years+ - NCT05642832Recruiting
Test a breathing-device method to reduce breathing effort
This trial checks whether a special “through-flow” system can safely reduce how hard your body has to breathe when you are on a breathing machine. It is mainly a feasibility study, meaning the focus is on whether the approach can be done safely and effectively.
Toronto, OntarioAges 18 years+ - NCT07572383RecruitingPhase 2
Imaging Study of Immunosuppression for Progressive Lung Fibrosis
This study uses advanced imaging to see how immunosuppressive medications (like mycophenolate or prednisone) affect lung scarring in patients with certain types of lung fibrosis. You would have imaging scans and breathing tests to track changes over time.
Boston, MassachusettsAges 18–80 - NCT07572773Recruiting
Lung cancer screening program for current and former smokers
This program offers lung cancer screening (using imaging tests) for people aged 50–77 with a significant smoking history. Early detection can help catch lung cancer at a more treatable stage.
Iowa City, IowaAges 50–77 - NCT07573098Recruiting
Digital Tool to Help Manage Your COPD at Home
This study tests a smartphone app designed to help you track and manage your COPD symptoms day-to-day. It includes a small device you use at home to measure your lung function, aiming to help you catch problems early and stay healthier.

NottinghamAges 18–65 - NCT07571317Recruiting
Predicting breathing tube removal success in ICU patients
This study tests whether two simple breathing measurements can predict whether patients in the ICU are ready to have their breathing tube removed. If successful, it could help doctors make safer decisions about when patients can breathe on their own.
Istanbul, IstanbulAges 18 years+ - NCT07576660RecruitingPhase 3
Dexamethasone for lung injury from sepsis
This trial tests whether the steroid dexamethasone can help people with sepsis who develop acute respiratory distress syndrome (ARDS), a severe lung injury. If you have an infection and need breathing support, this study may help find a better treatment.
