Recruiting studies
- NCT07848243RecruitingPhase 2

Test for reflux causes after proton pump pills fail
This study checks whether a special test of the esophagus after meals can find the exact reason for ongoing reflux symptoms when proton pump pills (PPIs) don’t help. It may help doctors choose the right next treatment for people whose reflux symptoms keep coming back.
Chambray-lès-ToursAges 18 years+ - NCT07816809Recruiting
Phage therapy for gut discomfort

Fort Collins, ColoradoAges 18–75 - NCT06205862RecruitingPhase 2
Fecal transplant for preventing colon polyp return
This study tests whether taking capsules of healthy bacteria (fecal microbiota transplant) can help prevent colon polyps from coming back after they have been removed. It might be an option for people who have had an adenoma polyp removed and want to reduce the chance of recurrence.
Guangzhou, GuangdongAges 18–75 - NCT06507683Recruiting
Radiation plus ripretinib for advanced GIST
This trial tests whether adding radiation therapy to the drug ripretinib can help people with advanced gastrointestinal stromal tumors (GIST) that can't be removed by surgery and have stopped responding to other treatments. It aims to see if this combination is safe and effective.
Chongqing, Chongqing MunicipalityAges 18–75 - NCT05606822Recruiting
Vacuum endoscopy for leaks after esophagus stomach surgery
This trial studies an endoscopic vacuum treatment (a suction device placed through an endoscope) to help heal a leak after surgery where food/drink pathways were connected (an anastomosis). If you had an esophago-gastric leak, this treatment may be part of your care plan and is being studied for effectiveness and safety.
AmsterdamAges 18 years+ - NCT06513598Recruiting
Finding infection signs after abdominal cancer surgery
This study looks for ways to better predict and catch infections after major abdominal cancer surgery. If you are having surgery for certain cancers (esophagus, stomach, pancreas, liver, bile ducts, colon, or rectum), the researchers will check your blood and other samples for early signs of infection so they can start treatment sooner.
VilniusAges 18 years+ - NCT04534543Recruiting
Imaging scans to personalize chemotherapy for liver spread of bowel cancer
This trial tests whether special liver imaging can help doctors choose or guide the best chemotherapy for people with liver metastases from gastrointestinal cancer. The study focuses on comparing imaging-based information with outcomes during common chemo treatments like CAPOX or FOLFOX.
AmsterdamAges 18 years+ - NCT07780318RecruitingPhase 1/Phase 2
BL-M08D for advanced solid tumors in the digestive tract
This study tests a new drug called BL-M08D for people with advanced solid tumors, especially those in the digestive tract (like stomach, colon, or pancreas). The goal is to see if it is safe and effective, and it might help shrink tumors or slow their growth.
Beijing, Beijing MunicipalityAges 18–75 - NCT07770425Recruiting
Measuring lesion size during gastrointestinal endoscopy
This study tests a new way to measure the size of abnormal areas found during a routine endoscopy procedure. It may help doctors make more accurate measurements, which could improve diagnosis and treatment planning.
Montreal, QuebecAges 18 years+ - NCT07769892Recruiting
Blood and stool test for digestive tract cancer screening
This study is testing a new way to screen for cancers of the digestive tract using a simple blood and stool test. It is for people who are already scheduled to have a digestive tract endoscopy, and it may help find cancers earlier without extra invasive procedures.
Zhaoqing, GuangdongAges 45–74 - NCT06505395RecruitingPhase 2
Octreotide injection for advanced neuroendocrine tumors
This trial is testing an injectable medicine called octreotide for people with advanced neuroendocrine tumors of the digestive system or pancreas. It aims to see if the medicine can help control the tumor.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06057415Recruiting
Gut nerve stimulation study for high-risk newborns
This study tests whether stimulating the nerves in the gut can help improve digestion in high-risk newborns, specifically those born very early or with a diaphragmatic hernia. It takes place at Amalia Children's Hospital and aims to find a way to help these babies' intestines work better.
NijmegenAges Up to 2 days - NCT07763860Recruiting
Music during endoscopy procedures
This study tests whether listening to music during an endoscopy (a tube with a camera used to look inside your digestive tract) can make the procedure more comfortable and less stressful. Participants will wear headphones and listen to music while the procedure is done under sedation.
SidonAges 18 years+ - NCT07763379Recruiting
Blood test for early detection of leaks after intestinal surgery
This study checks whether a simple blood test for C-reactive protein (CRP) can help doctors spot a leak early after intestinal surgery. A leak is a serious complication where the repaired area opens up, and early detection may lead to quicker treatment and better recovery.
Sohag, Sohag GovernorateAges 18–70 - NCT06579365Recruiting
Registry on H. pylori Infection Management in Argentina
This registry study tracks how H. pylori infection is managed in Argentina. It aims to collect real-world data to improve treatment for this common stomach infection.
Ciudad de Buenos AiresAges 18 years+ - NCT05828862Recruiting
Checks blood-pressure drops during major upper stomach surgery
This trial studies what happens when blood pressure drops during planned (elective) major upper gastrointestinal surgery and looks at related blood chemistry. Your care team may collect samples during the operation to understand why this happens and how to improve outcomes.
TaipeiAges 20–80 - NCT07755384Recruiting
Stomach and throat exam study at high altitude
This study looks at what doctors see in the upper digestive tract (stomach and food pipe) of people living at high altitude, using a sedated endoscopy (a camera tube down the throat while you sleep). It helps understand how high altitude affects the digestive system.
Yushu, QinghaiAges 18 years+ - NCT07749781Recruiting
