Houston, TexasAges 22 years+ - NCT06101277Recruiting
Local therapy for limited new cancer growth in digestive cancers
This trial tests a cancer treatment that uses local therapies (like radiation or targeted heat) to destroy a small number of growing spots. It is for people with certain gastrointestinal cancers whose main treatment is working well except for a few new spots, so they can avoid switching to a different drug right away.
Sacramento, CaliforniaAges 18 years+ - NCT05344417Recruiting
Low-pressure gas during colon surgery to reduce post-surgery gut slowdown
This study compares a low-pressure way of filling the abdomen with gas during certain colon surgeries. It aims to see whether this helps the bowel “wake up” faster after surgery (less postoperative ileus).
Columbus, OhioAges 18 years+ - NCT03800693RecruitingPhase 2
Shorter vs longer oxaliplatin infusions for gut cancer
This Phase 2 study compares giving oxaliplatin by IV for 2 hours versus 6 hours, along with the standard FOLFOX6 chemotherapy. It aims to see if the shorter infusion works as well and is manageable for people with gastrointestinal cancers.
Atlanta, GeorgiaAges 18 years+ - NCT06031584RecruitingPhase 1/Phase 2
Testing BL-M07D1 for HER2-positive or low solid tumors
This trial tests a new drug called BL-M07D1 for people with certain advanced solid tumors that have the HER2 protein (high or low amounts). The goal is to see if it can shrink or slow the growth of these cancers, especially in urinary and digestive system tumors.
Beijing, Beijing MunicipalityAges 18–75 - NCT05995821Recruiting
Blood and tissue collection for head and neck cancers
This study collects blood and tissue samples from people with cancers of the head, neck, or upper airway to learn how the immune system responds to these cancers. The goal is to find better ways to treat these diseases in the future.
Baltimore, MarylandAges 18 years+ - NCT05984589Recruiting

This study creates a registry for people with certain T-cell or NK-cell lymphomas. It collects health information and tumor samples to learn more about these diseases and improve future treatments.
Duarte, CaliforniaAges Any age - NCT05972291Recruiting
Study gut changes in Gulf War illness with chronic stomach symptoms
This study looks at what’s driving Gulf War illness, focusing on gut symptoms like belly pain, diarrhea, and bloating. It may help researchers test approaches aimed at gut barrier function in eligible veterans.
Memphis, TennesseeAges 18–65 - NCT05905016Recruiting
Testing an endoscopy procedure for gut movement problems
This study looks at how useful the POEM procedure is for people with gut “motility” (trouble moving food through the digestive tract). If you’re already scheduled for POEM, your team will also track how well it helps and whether it’s practical in real care.
Orlando, FloridaAges 18 years+ - NCT05884255RecruitingPhase 3
Lutetium brain-sparing therapy for advanced gut and pancreas tumors
This Phase 3 trial tests lutetium (Lu-177) oxodotreotide, a targeted treatment, for people with advanced gut and pancreas neuroendocrine tumors that are low or medium grade (G1 or G2). The study will see whether it helps control the cancer and symptoms in the right patients.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05846802Recruiting
Gastroparesis and stomach symptoms registry for adults
This registry is for adults with long-lasting stomach emptying problems or related symptoms, helping researchers better understand patterns of nausea, pain, and fullness. You may be able to join if you meet specific symptom and test results, and can complete a stomach-emptying scan.
Scottsdale, ArizonaAges 18–85 - NCT05812339Enrolling by invitation
Mapping tests for stomach symptoms using body-surface sensors
This study checks whether a noninvasive “mapping” test placed on the belly and chest can help tell apart people with certain upper stomach symptoms from healthy controls. It may help researchers better understand stomach function and symptoms without relying only on invasive tests.
Calgary, AlbertaAges 18 years+ - NCT05780684Recruiting
Personalized 5-FU dosing for advanced gastrointestinal cancer
This study tests whether doctors can safely find the best dose of 5-FU, a chemotherapy medicine, for people with advanced gastrointestinal cancers. The goal is to reduce side effects while still treating the cancer effectively.
Lebanon, New HampshireAges 18 years+ - NCT05692024RecruitingPhase 1/Phase 2
Coffee and gut bacteria study after colon or rectal cancer
This early-phase study tests whether a coffee-related approach can change gut bacteria and blood “metabolites” after treatment for stage I–III colon or rectal cancer. The goal is to learn if these changes could help improve health after standard cancer treatment.
Boston, MassachusettsAges 18 years+ - NCT05661643RecruitingPhase 2
Temozolomide for GIST tumors with SDH deficiency
This trial tests how well temozolomide works and how safe it is for people with GIST (a type of stomach/intestine tumor) that is SDH-deficient and has no KIT or PDGFRα mutations. It may help by targeting tumor DNA repair weakness seen in this SDH-deficient subtype.
Seoul, SeoulAges 20 years+ - NCT05664113RecruitingPhase 1
Fecal transplant for gut problems after stem cell transplant
This study tests whether transplanting healthy donor stool into the gut can help children and young adults with ongoing digestive issues after a stem cell transplant. It may improve symptoms like diarrhea or the need for feeding tubes.
Memphis, TennesseeAges Up to 22 years - NCT05600933Enrolling by invitation
Providing tumor samples to find new treatment targets
This study collects tumor tissue and related blood tests from people who already need a biopsy or surgery as part of their usual care. Researchers use the samples to learn what drives the tumor and how the tumor environment may affect treatment, which could help develop future therapies.
Bethesda, MarylandAges 18 years+ - NCT05482893RecruitingPhase 1/Phase 2
Study of spevatamig for advanced gastrointestinal cancers
This trial tests a new drug called spevatamig (PT886) alone or with other treatments for advanced stomach, gastric, pancreatic, bile duct, or colorectal cancers. The goal is to see if it helps slow or stop cancer growth.
Duarte, CaliforniaAges 18 years+ - NCT05501028Enrolling by invitation
Audio-recorded gut symptom interview to help diagnose FGIDs
This trial uses natural-language conversations (spoken interactions) to improve how clinicians evaluate and diagnose functional gastrointestinal disorders, a group of conditions that affect the gut. If you are scheduled for a GI clinic visit or a diagnostic endoscopy, your recorded responses may help build better evaluation tools.
Boston, MassachusettsAges 18 years+ - NCT05468008Recruiting
Study of endoscopic submucosal removal (ESD)
This trial is checking outcomes for adults who are scheduled to have a procedure called endoscopic submucosal dissection (ESD), done through an endoscope. If you’re already planned for ESD and have no reasons you can’t have endoscopy, you may be able to join.
Orlando, FloridaAges 18 years+ - NCT05500391RecruitingPhase 2
Testing whether remote nurse monitoring works like in-person checks
This Phase 2 study compares two ways of checking your cancer follow-up: a doctor or nurse visits in person versus remote monitoring by phone and imaging. The goal is to see whether remote monitoring can safely replace or match in-person care for certain low-risk cancers and after surgery.
AmiensAges 18 years+ - NCT05493215RecruitingPhase 2
Imatinib drug-monitoring for GIST with specific gene changes
This Phase 2 trial studies how to adjust and monitor imatinib (a targeted cancer medicine) based on drug levels in the blood. It may help people with GIST that has certain KIT or PDGFRA mutations but not the PDGFRA D842V type.
