GI symptom registry for adults with functional bowel issues
This study is a registry (a way to collect health information) for adults with certain long-term “functional” gastrointestinal (GI) problems. It may help doctors better understand these conditions and improve future treatments.
Boston, MassachusettsAges 18 years+ - NCT05051059Recruiting
Life quality check after leg sarcoma surgery
This study checks how people with leg sarcoma are functioning and how satisfied they are with their quality of life after treatment. It mainly looks at patients at least one year after limb-sparing surgery, to understand long-term effects and support.
Leuven, Vlaams-BrabantAges 18–95 - NCT04648124Recruiting
MRI brain scan study in hereditary retinal vision loss
This study uses functional MRI (a type of brain scan) to understand how the brain processes vision in people with inherited retinal disorders. You might be included if you are an adult with hereditary retinal degeneration and are planning certain vision-related treatments soon.
Paris, PARISAges 18 years+ - NCT04959526Recruiting
Testing lung stiffness and breathing function in healthy adults
This study compares a lung ultrasound method (shear-wave elastography) with breathing function tests to see how well they match. It may help researchers better understand how to measure lung health using imaging versus breathing tests.
Rochester, MinnesotaAges 18 years+ - NCT04918329Recruiting
Digestive symptom check-in study for adults
This study follows adults with long-lasting “functional” digestive symptoms as part of routine care. It may help researchers better understand these conditions and improve how they are managed.
RouenAges 18 years+ - NCT04883515Recruiting
Glutamine drink for insulin resistance and bowel symptoms
This trial studies whether taking an oral glutamine supplement can improve insulin resistance and reduce bowel-related problems in people with obesity and irritable bowel syndrome. It may help your blood sugar regulation and digestive comfort if you meet the criteria.
RouenAges 18–65 - NCT04849806Recruiting
Testing whether heart nerve signals predict COPD symptoms
This study looks at “sympathetic nerve activity” (signals from the nervous system that affect the heart) in adults with chronic obstructive pulmonary disease (COPD). The goal is to see whether these measurements can help predict what happens to people with COPD.
AachenAges 18 years+ - NCT02484248RecruitingPhase 3
Ketotifen for kids with stomach pain and duodenal eosinophilia
This study tests whether ketotifen can improve long-lasting stomach pain in children whose biopsies show high levels of a certain immune cell type in the small intestine. It may help if standard stomach-acid medicines and montelukast did not work well enough.
Kansas City, MissouriAges 8–17 - NCT04665739RecruitingPhase 2
Lutetium Lu-177 for lung carcinoid tumors with somatostatin receptors
This trial tests lutetium Lu 177 dotatate, a targeted radiation treatment, for advanced lung neuroendocrine (carcinoid) tumors that have a specific marker called somatostatin receptors. It may help shrink tumors by delivering radiation directly to cancer cells that “light up” on a special scan.
Birmingham, AlabamaAges 18 years+ - NCT04638088Recruiting
Robot or standard surgery for prostate removal
This trial compares different ways of doing a radical prostatectomy (surgery to remove the prostate): robot-assisted laparoscopy, conventional laparoscopy, or open surgery. It may help improve which approach is best for people having planned prostate removal.
AgenAges 18 years+ - NCT04676828Recruiting
