Checkpoint cancer drug given into or near tumors
This trial studies whether giving immunotherapy “checkpoint inhibitor” medicine directly into the tumor area (and/or the artery feeding it), along with a chemotherapy-style drug, can work better for advanced solid tumors. It aims to boost the immune system’s ability to attack cancer while still being safe for people with measurable tumors.
Guanzhou, GuangdongAges 18 years+ - NCT03758508Recruiting
Noninvasive breathing support versus high-flow oxygen for pneumonia
This study compares two ways to help breathing in adults with pneumonia who have low oxygen levels: a noninvasive breathing machine versus high-flow oxygen. It aims to see which option helps patients breathe better and avoid getting worse.
MilanAges 18 years+ - NCT03760575RecruitingPhase 1
Pembrolizumab plus chemo with surgery for pleural mesothelioma
This trial studies how well pembrolizumab (an immune therapy) works when added to chemotherapy before image-guided surgery for malignant pleural mesothelioma. It aims to shrink or control the cancer and improve surgical results by combining treatments.
Philadelphia, PennsylvaniaAges 18 years+ - NCT03762395RecruitingPhase 2
Study of anti-inflammatory asthma molecules in adults
This Phase 2 study tests anti-inflammatory lipid mediators in people with asthma. You may be eligible if your asthma is not well controlled despite regular inhaler use and you meet the specific lung function and health criteria.
Aurora, ColoradoAges 18–65 - NCT03769129Recruiting
Pembrolizumab plus lung ablation for advanced lung cancer
This trial tests whether combining pembrolizumab (an immune treatment) with a lung ablation procedure can be safer and more effective for advanced non-small cell lung cancer after standard first treatment fails or the cancer comes back. It may help shrink tumors and improve control of the disease.
Guangzhou, GuangdongAges 18 years+ - NCT03778814RecruitingPhase 1
Personalized T-cell therapy for advanced lung or solid tumors
This Phase 1 study tests a lab-made immune cell treatment made from your own blood cells (T cells) to fight advanced lung cancer or other solid tumors. You may be eligible if your tumor can be biopsied and the lab can successfully prepare T cells that strongly recognize and attack your cancer.
Guanzhou, GuangdongAges 18–75 - NCT03774758Recruiting
Blood tests to estimate lung cancer risk over 3 years
This study looks for blood “biomarkers” (measurable signs in blood) that may help predict who is at higher or lower risk related to lung cancer. You would have blood samples taken and then be followed with visits for up to 3 years.
San Francisco, CaliforniaAges 40 years+ - NCT03786003Recruiting
Compare two lung surgery approaches for stage I lung cancer
This trial studies whether a minimally invasive lung surgery (VATS) works as well as the more open approach (thoracotomy) for certain early-stage lung cancers. It may help patients and surgeons choose the best operation method for tumors that can be fully removed.
ShanghaiAges 18–75 - NCT03787056Recruiting
Blood test marker study in many cancer types
This study measures a blood marker called progastrin (at diagnosis and during treatment) to see how well it predicts response or outcomes. It may help doctors choose or monitor treatment more precisely for several cancer types.
BronAges 18 years+ - NCT03791034Recruiting
Blood DNA test to guide treatment in early lung cancer
This trial studies a “cell-free DNA” blood test to help diagnose and guide treatment decisions for early non-small cell lung cancer. It may help doctors tailor care based on genetic signals seen in the blood before and around surgery.
SeoulAges 18–90 - NCT03795662Recruiting
Surviving Pneumonia
This trial studies treatment for pneumonia by enrolling people who have pneumonia signs on a chest X-ray plus typical symptoms like fever, cough, trouble breathing, or chest pain. It may help doctors test approaches for better outcomes after pneumonia.
HillerødAges 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 - NCT03797183Recruiting
Check heart and lung function using a painless chest scan
This study uses a noninvasive scan that measures electrical signals across the chest to better understand breathing and heart-related circulation problems. It may help doctors learn what to monitor and how conditions like lung/airway pressure and vessel narrowing progress.
Aurora, ColoradoAges 2 weeks–40 years - NCT03800017Recruiting
Muscle strength and exercise function in lung scarring
This study looks at how well skeletal (muscle) function supports exercise in people with interstitial lung diseases (including idiopathic pulmonary fibrosis). It may help better understand fitness and breathing limits, which can guide rehabilitation choices and future care.
Vancouver, British ColumbiaAges 40–80 - NCT03803787RecruitingPhase 2
Inhaled steroid to prevent lung inflammation during cancer treatment
This trial tests whether breathing in steroid medicine before and during radiation can lower how often and how badly “radiation lung inflammation” (radiation pneumonitis) happens in people with lung cancer. If you qualify, it may help protect your lungs while you receive radiation with chemotherapy or targeted therapy.
Mexico CityAges 18–75 - NCT03805477RecruitingPhase 2
Nintedanib for lung scarring after bone marrow transplant
This trial tests nintedanib to slow or improve bronchiolitis obliterans syndrome (BOS), a type of lung scarring, after a hematopoietic stem cell transplant. You may be considered if your breathing tests and scans show BOS, and if active infections and certain health risks are ruled out.
RiyadhAges 18 years+ - NCT03807310Recruiting
Vitamin and fatty-acid supplement study for COPD recovery
This trial tests whether a targeted supplement (vitamins D and fatty acids) can help people with COPD. It’s meant for people who are medically stable and not currently dealing with a recent COPD flare-up.
Maastricht, LimburgAges 18 years+ - NCT03808337RecruitingPhase 2
SBRT radiation plus standard treatment for spread cancer
This trial looks at adding a focused radiation treatment called SBRT to standard care for cancers that have spread to a limited number of spots. It aims to control those spread-out tumors while still using the usual cancer treatment plan.
San Carlos, CaliforniaAges 18 years+ - NCT03808922RecruitingPhase 3
DAS181 treatment for COVID-19 lung infection in immune-compromised adults
This Phase 3 trial tests DAS181 to treat lower lung (chest) viral infections in people with weakened immune systems, including a COVID-19 subgroup. It may help by targeting certain viruses in the lungs, but joining depends on your oxygen needs, recent diagnosis, and other safety factors.
Duarte, CaliforniaAges Any age - NCT03819296RecruitingPhase 1
Fecal transplant to treat cancer immunotherapy bowel side effects
This early-phase study tests whether changing your gut bacteria with a fecal transplant can improve diarrhea or colitis caused by cancer immunotherapy. It may help people whose symptoms have not fully settled with standard treatments like steroids and other immune-blocking medicines.
Houston, TexasAges 18 years+ - NCT03827694Recruiting
Testing a noninvasive scan for serious lung mold infections in kids
This study uses noninvasive breathing/relates imaging (MRI or CT) to help diagnose mold infections in the lungs in children and young adults. It may help doctors find these infections sooner, especially in people with weakened immune systems.
Little Rock, ArkansasAges 4 months–21 years - NCT03830320RecruitingPhase 1
PET scan to look for blood clots in the heart or lungs
This Phase 1 study uses a PET scan to detect blood clots (thrombosis) in specific groups of people. It’s testing how well the scan can find clots and how it should be timed with other heart or illness tests.
Boston, MassachusettsAges 18–85 - NCT03839992Recruiting
Checks for hidden small airways blockage in cystic fibrosis
This trial looks for early, “hidden” breathing test abnormalities in people with cystic fibrosis who have normal routine lung test results. It may help researchers find blockage in smaller airways before it shows up on standard tests.
Lakewood, CaliforniaAges 5–40 - NCT03848052Recruiting
Study of lung cancer care in France since 2015
This trial tracks how lung cancer is treated in France, looking at what therapies were used and how care has evolved since 2015. It may help doctors improve future treatment choices by understanding real-world care patterns.
