Dallas, TexasAges 18 years+ - NCT05209568Enrolling by invitation
Study of immune reactions after eating gluten
This study looks at how your immune system responds when you eat gluten, including for people with celiac disease. You may be asked to follow a gluten-free diet first and then safely reintroduce gluten so researchers can measure immune changes.
Aurora, ColoradoAges 2–101 - NCT05212129Recruiting
Stimulation of the ear nerve to help gut symptoms
This study tests whether stimulating a nerve in the ear (called auricular vagal nerve stimulation) can improve upper gut symptoms in teens who may have hypermobile Ehlers-Danlos syndrome (hEDS) or hypermobile spectrum disorder (HSD). It also checks whether this treatment helps nerves that control the body (autonomic nervous system) and how well the gut moves.
Milwaukee, WisconsinAges 10–18 - NCT05196087Recruiting
AI system to monitor cancer treatment progress
This trial tests a non-invasive, AI-based monitoring program for people with solid tumors. It aims to help track how you’re doing during or after curative-intent treatment, using information collected without extra procedures.
Toronto, OntarioAges 18 years+ - NCT05132816Recruiting
Test manometry after partial anti-reflux surgery
This study checks how well a swallowing test called high-resolution manometry works after partial anti-reflux surgery. It focuses on adults with certain abnormal esophagus muscle patterns to help doctors understand what to expect after the operation.
Schlieren, Canton of ZurichAges 18 years+ - NCT05108844Recruiting
Testing a camera swallow exam for recent upper gut bleeding
This study tests whether a “videocapsule endoscopy” (a small camera you swallow) can find the cause of upper gastrointestinal bleeding when a first scope doesn’t show active bleeding. It may help doctors locate hidden bleeding sources and guide treatment.
Edmonton, AlbertaAges 18–90 - NCT00227253Recruiting
Study center for people with Chromosome 18
This trial is for people with Chromosome 18 (or the parent/guardian of a child with it) to take part in medical checkups and study evaluations. It may help researchers learn more about the condition and how to best evaluate patients safely.
San Antonio, TexasAges Any age - NCT04899908RecruitingPhase 2
Brain radiation with or without gadolinium nanoparticles for brain metastases
This trial tests whether adding tiny gadolinium-containing nanoparticles to standard brain radiation can better control brain metastases from certain cancers. It is for people with tumors that have grown after immunotherapy, are from certain cancers (like melanoma, GI, or HER2+ breast), are cystic, are large, or have come back after prior radiation.
Boston, MassachusettsAges 18 years+ - NCT04900597Recruiting
Testing blended tube feeds on kids’ stomach function
This study compares how “blended” tube feeds affect stomach and upper digestive function in children who use a feeding tube. It may help doctors understand whether blended feeds change digestion in ways that matter for comfort and physiology.
Boston, MassachusettsAges 1 year+ - NCT04847063RecruitingPhase 1
Test drug heating inside the abdomen for peritoneal cancer
This Phase 1 trial tests a treatment that delivers heated chemotherapy directly into the abdomen (HIPEC) for certain cancers that have spread only within the abdominal lining. It aims to see how safely and effectively this approach works, especially when doctors can remove as much tumor as possible.
Bethesda, MarylandAges 18–120 - NCT04674267Recruiting
Health and well-being study for older adults with gastrointestinal cancer
This study looks at how older adults with gastrointestinal cancer manage their health and well-being. It aims to understand and improve care for this group.
Boston, MassachusettsAges 65 years+ - NCT04629677Recruiting
Portal vein stent for narrowed portal blood vessels
This trial looks at whether placing a small metal stent in the portal vein and nearby veins can improve problems caused by major narrowing (or clotting) of these vessels in people with gastrointestinal cancers. If you have significant vessel narrowing, the study may offer a targeted way to relieve pressure and symptoms that are not caused by the tumor directly.
Houston, TexasAges 18 years+ - NCT04566341Enrolling by invitation
Study gut problems in Parkinson’s and changes in gut nerves
This study looks at how digestive (gut) problems happen in people with Parkinson’s and whether there are related changes in the nerve tissue in the digestive tract. It may help researchers better understand the cause of these symptoms and find new ways to monitor or treat them.
Boston, MassachusettsAges 40–85 - NCT04506593Recruiting
