Madison, WisconsinAges 7 years+ - NCT05294107Recruiting
Intestinal organoid study in digestive biopsies
This study collects small tissue samples (biopsies) during a routine endoscopy to create organoids—miniature versions of your intestine grown in a lab. The goal is to better understand digestive diseases and test potential treatments. You may be eligible if you're already scheduled for an endoscopy.
RennesAges 18–75 - NCT05294744Recruiting
N-acetylcysteine plus usual care for severe alcoholic hepatitis
This study tests whether adding N-acetylcysteine to standard treatment helps people with severe alcoholic hepatitis. It may improve liver outcomes, especially for those with a high Maddrey score.
Vitoria-Gasteiz, ÁlavaAges 18–75 - NCT05295680RecruitingPhase 2
Oral hymecromone for primary sclerosing cholangitis

Hamilton, New JerseyAges 18 years+ - NCT05297734Recruiting
Study compares two cancer support care plans
This study tests two different ways of providing supportive care for adults with cancer to see which one works better. It may help improve comfort, support, and care coordination during treatment.
Birmingham, AlabamaAges 18 years+ - NCT05298722Recruiting
MRI and blood tests to predict if pancreatic surgery is possible
This study looks at MRI scans, computer-extracted imaging features, and blood/“liquid biopsy” tests after FOLFIRINOX chemotherapy to predict whether surgery can fully remove pancreatic cancer. It may help your care team choose the best next step—whether surgery is likely to be possible and how to plan it.
Ghent, East FlandersAges 18 years+ - NCT05299840Recruiting
Test a device to choose the first chemo for metastatic colon cancer
This study tests whether using the Oncogramme® device to guide the first-line treatment improves care for people with metastatic colorectal (colon/rectum) cancer. If the device helps pick the most suitable standard chemotherapy plan, it could lead to better outcomes than choosing without it.
MarseilleAges 18 years+ - NCT05302531RecruitingPhase 1
Testing high-absorption antibiotics for short-bowel syndrome
This early (Phase 1) study tests how well certain antibiotics get absorbed in the body when you have short-bowel syndrome. It may help doctors choose antibiotics that work better through the mouth for people with this digestion problem.
Vandœuvre-lès-Nancy, LorraineAges 18 years+ - NCT05304234RecruitingPhase 2
Testing ways to detect liver cancer risk in Native patients
This Phase 2 study focuses on people at higher risk for liver cancer due to liver scarring or chronic hepatitis B. It may help improve screening and outcomes for American Indian and Alaska Native people who could benefit from closer monitoring.
Tahlequah, OklahomaAges 18–75 - NCT05308628Recruiting
Tests for liver scar (fibrosis) in children after liver transplant
This study checks how well a liver “fibrosis panel” test can evaluate scarring in children who have had their first liver transplant. Your child may be helped by getting extra monitoring of liver scarring, and the study may improve how doctors assess recovery and risk over time.
ShanghaiAges 2 months–18 years - NCT05309863Recruiting
Compare home versus clinic weight programs for fatty liver
This study compares two weight-loss programs for children with fatty liver disease related to weight, to see which helps the liver and health better. You may be eligible if your child is already enrolled in a lifestyle program for childhood obesity and meets key safety checks.
Ghent, East-FlandersAges 8–18 - NCT05310643RecruitingPhase 2
Nivolumab and ipilimumab for bowel cancer resistant to anti-PD1
This Phase 2 study tests two immunotherapy medicines (nivolumab and ipilimumab) in people with metastatic colorectal cancer that has not responded to anti-PD1 treatment. It focuses on tumors with mismatch repair problems (dMMR) and/or high microsatellite instability (MSI).
BesançonAges 18 years+ - NCT05313191Recruiting
Proton therapy for tumors after prior radiation
This study looks at whether a type of proton beam treatment can be given safely and effectively to tumors that have already been treated with radiation before. It may help people whose tumors came back or persisted after earlier radiation, using a specific proton method called pencil beam scanning.
New York, New YorkAges 18 years+ - NCT05313620RecruitingPhase 4
Tofacitinib effect on clotting tests in ulcerative colitis
This study looks at how tofacitinib (and related medicines) may affect clotting and blood-platelet function, and whether this could relate to blood clot risk. It includes detailed blood and stool/colonoscopy-related testing in adults with ulcerative colitis and in some people without it.
Madrid, MadridAges 18 years+ - NCT05314400Recruiting
MRI with contrast for metastatic colon cancer liver lesions
This trial studies an MRI technique using a contrast dye (gadopetate/gadolinium) to better look at liver lesions that may be colon cancer spread. It may help doctors more accurately assess which liver tumors are present and guide next steps.
London, OntarioAges 18 years+ - NCT05316103Recruiting
Optical biopsy of rectal scars after cancer treatment
This trial tests a targeted “optical biopsy” (using a special light-based exam to sample tissue) to better assess rectal scars after standard chemotherapy and radiation before surgery. It may help surgeons choose the most appropriate way to operate on rectal cancer.
Guangzhou, GuangdongAges 18–80 - NCT05317819RecruitingPhase 3
Test ADI-PEG 20 versus placebo for advanced liver cancer
This study tests whether ADI-PEG 20 helps people with advanced, unresectable hepatocellular carcinoma (liver cancer) who have high arginine levels. Participants get ADI-PEG 20 or a placebo to see which works better and improves outcomes.
ChanghuaAges 18–99 - NCT05319314RecruitingPhase 1/Phase 2
Study drug for advanced colon cancer that has come back or failed
This Phase 1/2 trial tests LYL273, a new targeted treatment, for people with metastatic colorectal (colon) cancer that has returned or not responded to standard chemo. It’s designed to see how well the drug can control the cancer and what side effects it causes.
Duarte, CaliforniaAges 18 years+ - NCT05319639RecruitingPhase 1/Phase 2
Irinotecan plus immunotherapy for stomach cancer
This Phase I/II trial tests how well irinotecan combined with tislelizumab (an immunotherapy) treats advanced stomach or gastroesophageal junction adenocarcinoma. It mainly looks at safety and the best way to use this combination, and may help shrink tumors or slow disease growth.
Fuzhou, FujianAges 18–75 - NCT05320796RecruitingPhase 4
Esomeprazole study after gastric bypass and pouch acid levels
This trial tests how well esomeprazole (a acid-reducing medicine) works after a Roux-en-Y gastric bypass, and how it changes the acidity in the stomach pouch. It may help confirm the best way to control stomach acid after bypass surgery.
Schlieren, SchlierenAges 18 years+ - NCT05321134Recruiting
Testing single-port robot surgery for colorectal conditions
This study checks how well a newer single-opening (single-port) robot works for colorectal surgery. It may help surgeons perform operations with the robotic system in carefully selected colorectal conditions.

Stool transplant as first treatment for kids with Crohn’s
This study tests whether transferring healthy gut bacteria from stool into the colon can work as a first treatment for children newly diagnosed with mild-to-moderate Crohn’s disease. It may help reduce inflammation and improve symptoms, and it requires regular colonoscopy to monitor progress.
Wuhan, HubeiAges 2–16 - NCT05323201RecruitingPhase 1/Phase 2
B7H3 CAR-T therapy for advanced liver cancer
This trial tests an immune therapy made from your own blood cells (CAR-T) to treat advanced, unresectable liver cancer. It’s designed for people whose tumor has a specific marker called B7H3 and who meet blood, organ, and safety requirements.
