This study looks at what factors may make COVID-19 symptoms or infection effects last after someone has recovered. It also collects certain body samples to better understand why this persistence happens.
New York, New YorkAges 7 years+ - NCT04451473Recruiting
Compare recovery programs after lung surgery
This trial compares two ways of helping patients recover after lung surgery: a “enhanced recovery” plan versus standard care. It may help your team find a recovery approach that improves comfort and recovery after surgery for certain lung problems.
Jinan, ShandongAges 18–85 - NCT04457154Recruiting
Registry for teens and young adults with OSA who can’t use CPAP
This study collects information in a registry to help doctors understand outcomes for young people with moderate-to-severe obstructive sleep apnea who cannot use CPAP and may use an implantable breathing stimulation device. You might qualify if you’ve tried and couldn’t tolerate CPAP and you’re able/willing to get and use the device and return for follow-ups and sleep tests.
Aurora, ColoradoAges 18–21 - NCT04459065RecruitingPhase 1/Phase 2
Imaging medicine to help find lung cancer during surgery
This trial tests a special imaging drug (IRDye800CW-nimotuzumab) that may help surgeons better see lung cancer tissue during planned lung surgery. Phase 1/2 looks mainly at safety and how well the imaging works to guide the operation.
Saskatoon, SaskatchewanAges 18–80 - NCT04460859Recruiting
Testing an electrical monitor in moderately severe lung failure
This trial tests a bedside breathing and lung-monitoring method that uses small electrodes on the chest. It is meant for people with moderate to severe ARDS (a serious lung inflammation problem) who are on a breathing machine, to help guide care.
São PauloAges 18 years+ - NCT04461821Recruiting
Breath test to study disease in children
This study uses a special machine to analyze exhaled breath to learn about different illnesses in children and teens. It may help researchers find breathing “signals” that reflect conditions like breathing problems, nervous system issues, or new/worsening type 1 diabetes.
BaselAges Up to 22 years - NCT04467723RecruitingPhase 1/Phase 2
Atezolizumab plus pirfenidone for advanced lung cancer
This Phase 1/2 trial tests whether combining atezolizumab and pirfenidone can help people with non-small cell lung cancer (NSCLC) after prior treatment. It is aimed at patients whose cancer has certain genetic markers ruled out and who can safely take study medicines and follow frequent visits.
Fairway, KansasAges 18 years+ - NCT04469439Recruiting
Sinus surgery in adults with cystic fibrosis
This study looks at how endoscopic sinus surgery affects people with cystic fibrosis who have ongoing sinus problems even after medical treatments. It may help doctors understand whether surgery plus ongoing care improves symptoms and quality of life.
Los Angeles, CaliforniaAges 18–99 - NCT04471493Recruiting
Study of children’s common infections in a clinic program
This trial is for children under 16 who have one of several common infections seen in outpatient or clinic visits. It aims to better study and manage these illnesses using a specific clinical documentation software.
CréteilAges 1 day–16 years - NCT04471740Recruiting
Study of hydrocephalus and sleep apnea
This study looks at people who may have normal-pressure hydrocephalus (fluid-related swelling in the brain) and also focuses on sleep apnea. It may help researchers understand whether treating or studying sleep issues could improve symptoms related to this condition.
Valencia, ValenciaAges 18 years+ - NCT04472260Recruiting
Testing safe early standing for adults with severe lung failure
This trial checks whether it’s safe and doable to help people with acute respiratory distress syndrome (ARDS) start standing early, while they are closely monitored. It may help some patients begin upright movement sooner, with the goal of improving safety.
OrléansAges 18 years+ - NCT04474301Recruiting
Quality of life check for people with melanoma during COVID-19
This study looks at how people with melanoma are feeling during the COVID-19 pandemic, including quality of life. You may be asked to share information through surveys or study contact so the researchers can understand needs and concerns.
Houston, TexasAges Any age - NCT04477460Recruiting
Testing thicker feeds for babies after unexplained brief events
This trial looks at whether using thicker baby feeds can improve health outcomes for infants who have had their first “brief resolved unexplained event” (a short episode with no clear cause). It may help babies who are being monitored after this first episode.
Boston, MassachusettsAges birth–1 year - NCT04484727Recruiting
Measure lung pressure and breathing in ventilated ICU patients
This study measures lung pressures and breathing mechanics during planned or emergency breathing machine (ventilator) treatment. It may help doctors better understand lung behavior in both healthy and breathing-distressed lungs to improve care.
Gothenburg, Västra Götaland CountyAges 18 years+ - NCT04485013RecruitingPhase 1
Study drug TTX-080 for advanced colorectal cancer
This Phase 1 study tests TTX-080, a drug designed to block a cancer immune “signal” (HLA-G) to help the body fight advanced colorectal cancer. It mainly checks safety and how the treatment works in people with cancer that has spread.
Tucson, ArizonaAges 18 years+ - NCT04486833RecruitingPhase 1/Phase 2
Genetic-targeted drug plus gene medicine for EGFR lung cancer
This trial studies a gene-based treatment added to osimertinib (a targeted lung cancer pill) for advanced EGFR-mutant lung cancer that has started growing again on osimertinib. It may help by attacking the cancer with both its usual target treatment and an added genetic approach.
Los Angeles, CaliforniaAges 18 years+ - NCT04494776Recruiting
Study of COVID-19 in kidney transplant patients
This study looks at what happens when people with kidney transplants get COVID-19. It may help improve how doctors monitor and manage COVID-19 in transplant recipients.
São Paulo, Aão PauloAges Any age - NCT04498598Recruiting
Test a modified breathing device for the voice box area
This study tests a modified supraglottic airway device (a type of breathing aid placed above the vocal cords) during surgeries done under general anesthesia. It may help researchers see if a better-shaped device works more safely during planned surgeries that use muscle relaxation.

Testing thickened feeds to improve safe swallowing
This study looks at how using thickened feeds may change swallowing safety and function in children who have swallowing problems (dysphagia) or who are at risk for a type of concerning breathing event. The goal is to see whether thicker liquids help protect the airway and improve swallow patterns.
Boston, MassachusettsAges Up to 21 years - NCT04506359Recruiting
