Blood tests to study tumor markers
This trial looks at blood samples to measure substances that may reflect cancer (tumor markers). It may help doctors understand cancer better and improve future monitoring, as long as you can safely and regularly take part.

Study early lung, virus, and gut changes in children with cystic fibrosis
This study looks at how a child’s early lung function, viral infections, and gut (microbiome) changes affect cystic fibrosis over time. It may help doctors understand what predicts how lung disease develops, which could improve future care.
BernAges birth–18 years - NCT04031950Recruiting
Testing a sleep sensor for children suspected of sleep apnea
This study tests a child sleep “sensor” device in kids who have been referred to a sleep clinic because sleep apnea is suspected. It may help doctors diagnose sleep problems more easily using extra information from the sensor.

Fecal transplant for immune-therapy diarrhea or bowel inflammation
This early-phase study tests whether stool/fecal microbiota transplant (a fecal transplant) can help people who develop significant diarrhea or colitis after immune-checkpoint therapy. It aims to reduce bowel inflammation and improve symptoms, while carefully checking for infections.
Houston, TexasAges 18 years+ - NCT04045587Recruiting
Registry for severe asthma in adults in Canada
This is a research registry that collects health information from adults with severe asthma to better understand how the condition behaves and how treatments are used. You may be able to take part if your asthma is considered severe and is not well controlled.
Edmonton, AlbertaAges 18 years+ - NCT04057209Recruiting
Voice outcomes after laser surgery vs radiation for early vocal cord cancer
This trial compares two treatments—CO2 laser surgery through the mouth versus one-vocal-cord irradiation—for early-stage larynx (voice box) cancer. It aims to see which option better preserves voice quality after treatment.
ParisAges 18 years+ - NCT04058457Recruiting
Deep brain stimulation for people with Parkinson’s
This study looks at how deep brain stimulation (DBS) affects breathing in people who have Parkinson’s disease and are planning DBS surgery. You may be able to help researchers learn whether DBS changes breathing and how to manage it safely.
Oxford, OxfordshireAges 18 years+ - NCT04062565RecruitingPhase 3
Testing treprostinil plus riociguat for advanced pulmonary artery hypertension
This study tests whether taking injected treprostinil together with riociguat can improve how the heart and lung blood vessels work in people with advanced pulmonary artery hypertension (PAH). It may help improve blood-flow measurements and the structure of the heart.
Tucson, ArizonaAges 18 years+ - NCT04063501Recruiting
Study of gut microbes during immunotherapy for lung cancer
This trial studies how gut bacteria (the microbiome) and the body’s immune signs change over time while you receive PD-1–based immunotherapy for advanced, unresectable non–small cell lung cancer. The goal is to learn which immune and microbial patterns might relate to how well treatment works and how patients respond.
New York, New YorkAges 18–100 - NCT04067830RecruitingPhase 2
Breathing muscle training before lung surgery to prevent complications
This trial tests whether training your breathing muscles before lung surgery can reduce lung problems after surgery in people with stage I to IIIb lung cancer. It may help improve breathing and lower the chance of post-surgery lung complications.
Buffalo, New YorkAges 18 years+ - NCT04068012Recruiting
Test of a decision support tool for children with PARDS
This trial tests a computer “decision support” tool to help the care team manage treatment for children with PARDS who are just starting a breathing machine. It may help clinicians choose care steps and potentially support safer, more effective breathing management during the first days of ventilation.
Chicago, IllinoisAges 1 month–18 years - NCT04071327Recruiting
Pulmonary hypertension registry for patient experiences
This trial is a registry that collects health information from people with pulmonary hypertension to better understand the disease and improve care. You may be asked to share details about your diagnosis and visits, especially soon after you start seeing a specialized PH care center.
Phoenix, ArizonaAges birth+ - NCT04075305Recruiting
Study measuring radiation treatment outcomes with an MR-Linac
This study follows what happens when radiation treatment is guided using an MR-Linac (a special machine that combines MRI imaging with radiation). It may help improve how radiation therapy is planned and assessed, especially for people who can safely have MRI scans.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT04077099RecruitingPhase 1/Phase 2
Study drug for lung cancer with MET changes
This trial tests REGN5093, a study drug, in adults with advanced lung cancer that has a specific change called a MET alteration. If you have this MET change, the study aims to see how well the drug controls the cancer and how safe it is.
Birmingham, AlabamaAges 18 years+ - NCT04078243Recruiting
Trial setup and testing in adults with pulmonary hypertension
This study tests new “trial tools” and designs for running early research in people with pulmonary hypertension. If you qualify, you may be asked to do extra trial-related procedures to help researchers test the process safely and smoothly.
Sheffield, South YorkshireAges 18 years+ - NCT04079179RecruitingPhase 2
Cobimetinib for difficult Langerhans cell and similar disorders
This Phase 2 trial studies cobimetinib, a medicine that targets a specific growth-and-signal pathway, to treat stubborn (refractory or worsening) Langerhans cell histiocytosis and related disorders. It may help shrink active disease or stop disease from progressing.
Phoenix, ArizonaAges Any age - NCT04083417RecruitingPhase 4
Sore throat study comparing antibiotics versus no antibiotics
This trial looks at whether phenoxymethylpenicillin (an antibiotic) helps people with a certain type of sore throat more than not using antibiotics. You may qualify if your symptoms match a likely bacterial cause and a rapid test for strep is negative.
JönköpingAges 15 years+ - NCT04086082Recruiting

Mouth guard study to reduce airway collapse in sleep apnea
This study tests whether using an anti-snoring mouth guard (a mandibular advancement appliance) can help keep your airway open during sleep if you have obstructive sleep apnea. If you’re referred for this kind of mouth guard, the trial will see if using it more regularly or in a specific way improves symptoms or breathing during sleep.
