Studying the immune system in Crohn's and colitis
This study collects blood and tissue samples to better understand how the immune system behaves in people with inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis. It aims to advance research rather than test a specific new treatment, and it also enrolls healthy volunteers for comparison.
Bethesda, MarylandAges 1 day–75 years - NCT07027826Recruiting
String test for eosinophilic esophagitis in African patients
This study tests a new, less invasive way (the Esophageal String Test) to look for signs of eosinophilic esophagitis—an allergic condition that can make swallowing painful or difficult. It is for people of African descent who have trouble swallowing and are already having an endoscopy.
Bethesda, MarylandAges 18–65 - NCT07328516Enrolling by invitation
Farm childhood health study for adult children
This study looks at how early-life exposures on farms might influence long-term health. If you are an adult child of a farmer or farmworker from the Agricultural Health Study, and you spent time on a farm as a child, you may be able to join.
Bethesda, MarylandAges 18–99 - NCT07659795RecruitingPhase 2
Study of VS-7375 for KRAS G12D colorectal cancer
This trial tests a new targeted pill, VS-7375, for people with a specific type of advanced colorectal cancer called KRAS G12D. It's for those who either haven't had treatment yet or whose cancer has worsened after prior therapy.
Los Angeles, CaliforniaAges 18 years+ - NCT05901519RecruitingPhase 2
Prednisone to protect the liver during focused radiation for liver cancer
This trial tests whether prednisone (an anti-inflammatory steroid) can help protect the liver in people with hepatocellular carcinoma who are getting stereotactic body radiation therapy. It may reduce liver stress from radiation and help you tolerate treatment safely.
Ann Arbor, MichiganAges 18 years+ - NCT07585890Recruiting
Liver Transplant Outcomes With Machine Preservation in Europe
This study collects information about how livers do after transplantation when they've been preserved using machine perfusion—a technique that keeps donor livers in better condition before surgery. Researchers want to understand which preservation methods work best to improve transplant success across Europe.
InnsbruckAges 18 years+ - NCT06215716RecruitingPhase 3
Efruxifermin for NASH/MASH with liver scarring
This study tests a new medicine, efruxifermin, for people with NASH/MASH (fatty liver disease) and moderate liver scarring. It aims to see if the drug can help improve the liver's condition.
Birmingham, AlabamaAges 18–80 - NCT02504853Recruiting
Study food allergy patterns and genetics over time
This study follows people with food allergy and some closely related or healthy people to learn how food allergy (and related conditions) develops over time. It may help researchers find causes and better ways to predict and treat food allergy.
Bethesda, MarylandAges 1 day–99 years - NCT07721181Recruiting
STEP-UP: Higher radiation for recurrent rectal cancer
This trial tests giving a higher dose of radiation to people whose rectal cancer has come back in the pelvis after surgery and cannot be removed. It aims to see if more radiation can help control the tumor when surgery is not an option.
Maastricht, LimburgAges 18 years+ - NCT00575133Recruiting
Study of people with fatty liver disease
This study follows people who have been confirmed to have fatty liver disease seen on a liver sample. It aims to understand the condition over time and how different causes and health factors may affect it.
Zurich, Canton of ZurichAges 18 years+ - NCT02869477Recruiting
Cardia cancer database study
This study collects and stores medical information from people with cardia cancer. The goal is to better understand care and outcomes over time, which may help improve future treatment planning.
Marseille, Bouches-du RhôneAges 18–95 - NCT02518542Recruiting
POEM and stretching treatment for achalasia
This trial looks at a procedure called POEM, followed by prolonged stretching, to treat swallowing problems caused by specific esophagus muscle disorders. If you have the right diagnosis and can safely have an endoscopy, this may help improve how well food moves through your esophagus.
ViennaAges 18 years+ - NCT02038517Recruiting
Liver transplant waitlist study for people without diabetes
