CologneAges 6 months–18 years - NCT02323945Recruiting
Low-oxygen breathing to improve leg movement after spinal injury
This study tests whether breathing brief, mild low-oxygen air (under supervision) can improve leg mobility in people with a certain type of spinal cord injury. It may help with regaining movement, especially if you can already move your legs voluntarily but still have mobility limits.
Cambridge, MassachusettsAges 18–75 - NCT02630121RecruitingPhase 4
Nasal spray treatment to reduce mild sleep apnea congestion
This study tests whether using oxymetazoline with fluticasone nasal spray can improve mild obstructive sleep apnea by lowering nasal congestion. If your nose stays blocked most days despite current spray use, this may help your breathing during sleep.
Tampa, FloridaAges 18–65 - NCT02738645Recruiting
Study of pneumonia patients in the ICU
This study follows people who are admitted to a respiratory intensive care unit (a special ICU for breathing problems) because they have pneumonia. It may help doctors better understand pneumonia in ICU patients and improve care in the future.
Beijing, Beijing MunicipalityAges 18 years+ - NCT02527486Recruiting
Airways registry study for people with COPD symptoms
This registry collects information from people with COPD (and sometimes overlapping asthma-COPD features) to better understand breathing problems and airways behavior. It may help researchers learn which patterns match different symptom types, without necessarily using a new drug.
Seongnam-si, Gyeonggi-doAges 20–90 - NCT02391519Recruiting
Study how high altitude affects body energy signaling
This study compares how the body responds to high altitude around the time of a planned C-section, including a signal involved in energy use. It may help researchers understand why pregnancy and blood-vessel function can differ at higher elevations.
Aurora, ColoradoAges 18–45 - NCT02803242Recruiting
Patient research network for people with lung symptoms
This trial enrolls adults to help build a patient-powered research network for chronic lung disease. If you join, you’ll likely be asked to complete surveys or provide information to help researchers learn how symptoms and health outcomes change over time.
Washington D.C., District of ColumbiaAges 18 years+ - NCT02734069Recruiting
Testing whether muscle mass affects carboplatin side effects
This study looks at how your body’s “fat-free mass” (mostly muscle and organs) may change the dose of carboplatin and the risk of chemotherapy side effects. It’s for people with advanced lung cancer who are starting treatment with carboplatin plus paclitaxel for the first time.
Mexico CityAges 18 years+ - NCT02691689Recruiting
Genetics study in families with congenital heart defects and PAH
This study looks at genes that may contribute to pulmonary arterial hypertension (PAH) in people born with certain heart “shunts” (holes between heart chambers). If you have (or your family has) ASD or VSD and PAH confirmed by a heart pressure test, you may be invited to share genetic and health information to help researchers understand risk and better target future care.
LeuvenAges 18 years+ - NCT02918188RecruitingPhase 2
Hydrogen therapy for steroid-resistant graft-versus-host disease
This Phase 2 study tests whether hydrogen therapy can improve symptoms in people with chronic graft-versus-host disease (cGVHD) who cannot tolerate steroid treatment. If steroids aren’t working or can’t be used, this trial may offer an alternative approach to help control the illness.
Beijing, Beijing MunicipalityAges Up to 65 years - NCT02448992RecruitingPhase 2/Phase 3
Brain radiation that avoids the memory area in lung cancer
This trial studies a “prophylactic” (preventive) type of brain radiation for people with lung cancer that has spread to nearby lymph nodes but not to the brain. It aims to lower the chance of brain metastases while protecting the hippocampus, an area linked to memory.
TaoyuanAges 18–80 - NCT02468024RecruitingPhase 3
Surgery or focused radiation for early lung cancer
This study compares two treatments—removing only part of the lung (sublobar resection) versus a focused radiation approach (stereotactic ablative radiotherapy)—for early-stage non-small cell lung cancer. It aims to see which option works better with fewer problems for the right patients.
La Jolla, CaliforniaAges 18 years+ - NCT02670707RecruitingPhase 3
Vinblastine plus prednisone versus cytarabine alone for LCH
This phase 3 study compares two treatment plans for Langerhans cell histiocytosis (LCH): vinblastine plus prednisone versus cytarabine alone. It aims to find which approach works better and is safer for children and young adults with LCH that needs medicines.
Palo Alto, CaliforniaAges Up to 21 years - NCT02622581Recruiting
Lung cancer testing and treatment outcomes research study platform
This study collects information from adults with different types and stages of lung cancer to connect molecular test results with treatment choices and outcomes. It may help improve how lung cancer is diagnosed and managed by building a better understanding of what works for different patients.
OldenburgAges 18 years+ - NCT02777879Recruiting
Study gut-like lung bacteria and inflammation in early COPD
This study looks at the lung’s tiny bacteria (microbiome) and inflammation in people with early COPD who have a smoking history. It compares them with smokers who have normal breathing tests, to better understand what may drive COPD early on.
New York, New YorkAges 18–70 - NCT02821299Recruiting
Larynx transplant for people with permanent loss of voice
This study looks at whether a larynx (voice box) transplant can help people who have permanent loss of laryngeal function. It is a very small early evaluation (only 3 patients) and would require major surgery and medicines that lower the immune system.
LyonAges 18–60 - NCT03004326Recruiting
Biopsy study to test skin inflammation gene signals
This study uses a skin biopsy to look at “gene signals” (transcriptomics) in patients with active vasculitis that shows up on the skin. It may help researchers understand what is happening in your disease and how different types of vasculitis differ.
Los Angeles, CaliforniaAges 5 years+ - NCT03215836Recruiting
Study obesity and metabolism in adults with asthma
This study looks at how weight and blood-sugar/fat changes in the body may affect the airways in people with asthma. You may be asked to complete breathing tests and possibly an airway procedure (bronchoscopy) to help researchers compare groups.
Aurora, ColoradoAges 18–65 - NCT03193567RecruitingPhase 1
Cell therapy study for advanced lung cancer after treatment failure
This Phase 1 trial tests a powerful “killing cell” therapy for people with advanced non-small cell lung cancer whose cancer did not respond to standard chemotherapy and targeted drugs. The goal is to see if this new treatment is safe and may work after other treatments have failed.
ShanghaiAges 18–70 - NCT02919930Recruiting
Testing a new breathing support choice for central sleep apnea
This study looks at which settings to use for adaptive servo-ventilation (ASV), a machine that helps breathing during sleep. It is meant for people with central sleep apnea who are not getting enough benefit from CPAP, so ASV may be a better match.
LeuvenAges 18 years+ - NCT03042221Recruiting
Early re-biopsy to find why tumors survive targeted drugs
This study takes a small tumor sample early after starting targeted treatment (or uses blood if a biopsy isn’t possible) to look for clues—called biomarkers—about why some tumor cells survive. The results may help improve how future patients’ treatments are chosen for certain lung cancer gene mutations.
Aurora, ColoradoAges 18–85 - NCT03044223Recruiting
Profiles of immune cells in severe Pseudomonas sepsis
This study looks at patterns of immune cells in people who are critically ill with sepsis caused by Pseudomonas aeruginosa bacteria. It may help doctors better understand how the immune system responds and improve care for this serious infection.
