IV fluids to prevent pancreas inflammation after ERCP
This study tests whether giving IV (through-the-vein) fluids during/around an ERCP procedure can lower the risk of painful pancreas inflammation afterward. It may help patients by reducing a common complication after ERCP.
Calgary, AlbertaAges 18 years+ - NCT05098197RecruitingEarly Phase 1
Study of TIL cell therapy for advanced liver, bile, or pancreas cancer
This trial studies a treatment called TIL therapy, which uses your own immune cells grown from a tumor sample, to treat advanced cancers of the liver/bile ducts or pancreas. It’s mainly for people whose standard treatments have already failed (or none exist), and who can safely provide tumor tissue for the cell preparation.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05169242Recruiting
Preventing bleeding after colonoscopy using preventive clip placement
This trial tests whether placing small “preventive clips” during colonoscopy can reduce bleeding afterward in people who take blood thinners (DOACs). It may help lower the chance of bleeding after polyp removal or biopsy during a scheduled colonoscopy.
Shatin, New TerritoriesAges 18 years+ - NCT05064124Recruiting
Real-time healthcare system during colonoscopy for colon cancer
This study tests a new real-time healthcare system meant to improve how doctors find and monitor colon cancer risk during colonoscopy. You might be able to take part if you are scheduled for a non-emergency colonoscopy and meet other safety and medical criteria.
LondonAges 18 years+ - NCT05247112Recruiting
Tracking antibiotic resistance in H. pylori infections in Korea
This study looks at how resistant H. pylori (a stomach germ) is to different antibiotics in Korea. It uses stomach endoscopy samples to test which antibiotics may or may not work, helping guide future treatment choices.
Seongnam-si, Gyeonggi-doAges Any age - NCT05402696Recruiting
Study of advanced surgery care for colorectal tumors
This study follows adults who are referred for treatment of a specific type of colorectal tumor that involves the left side of the colon. It aims to improve care and outcomes for people needing advanced surgery.
Saint Cloud, MinnesotaAges 18 years+ - NCT04742621Recruiting
Liver transplant for colon cancer that spread only to the liver
This trial studies using a liver transplant to treat colon or rectal cancer that has spread to the liver but not anywhere else. It may help people with limited liver-only spread whose disease hasn’t worsened for a while.
New York, New YorkAges 18–65 - NCT05332444RecruitingPhase 4
Check if stomach-bacteria testing improves rescue treatment for H. pylori
This study compares two ways to treat Helicobacter pylori (H. pylori) infection that didn’t go away with prior therapy. One approach uses test results to guide which medicines to use, and the other uses standard (“empiric”) treatment. The goal is to see which works better and more safely as a rescue plan.
TaipeiAges 20 years+ - NCT04838522Recruiting
Prucalopride for constipation in breastfeeding women
This study looks at whether prucalopride (Motegrity/Resotran) can help constipation symptoms in women who are breastfeeding. It also monitors the breastfeeding infant during the study while you follow sample-collection and interview requirements.
La Jolla, CaliforniaAges 18 years+ - NCT04623359Recruiting
Testing a detailed bowel pressure test for hard-to-treat constipation
This study checks whether a “high-resolution manometry” test (a thin tube measuring bowel muscle pressure) helps doctors understand and manage constipation. It’s for adults with long-lasting constipation that has not improved with standard laxatives, and who meet specific safety and colon-testing criteria.
CaenAges 18 years+ - NCT05601505RecruitingPhase 2
DNA blood test–guided treatment before rectal cancer surgery
This trial uses a special DNA blood test (circulating tumor DNA) to help guide chemotherapy and radiation before surgery for locally advanced rectal cancer. It aims to improve outcomes by tailoring treatment based on the DNA signals from the tumor.
Beijing, Beijing MunicipalityAges 18–75 - NCT04682158RecruitingPhase 2
Propranolol added to standard chemoradiation for esophageal cancer
This trial studies whether adding propranolol (a common blood-pressure/heart medication) to standard chemotherapy and radiation can improve outcomes for people with esophageal adenocarcinoma. You would start propranolol around the time of treatment, with careful heart monitoring and study follow-up.
Buffalo, New YorkAges 18 years+ - NCT04615546Recruiting
Study nutrient flow in people with low blood sugar after surgery
This study looks at how food moves through the body and how that may affect episodes of low blood sugar caused by too much insulin. It may help researchers better understand and possibly improve care for people who get hypoglycemia, especially after bariatric (weight-loss) surgery.
Stanford, CaliforniaAges 18 years+ - NCT04706611Recruiting
Stool transplant to treat gut and immune-related conditions
This trial studies fecal microbiota transplantation (a stool-based treatment) to improve symptoms and safety in people with certain gut and immune conditions. It aims to see whether changing gut bacteria can help you feel better.
Guangzhou, GuangdongAges 18–70 - NCT04926103Recruiting
Fecal transplant program for active ulcerative colitis donors
This trial screens people as potential donors for a fecal microbiota transplant program used for ulcerative colitis. It checks safety and eligibility so the transplant process is as safe as possible for people with active disease.
Hamilton, OntarioAges 18 years+ - NCT04622540Recruiting
Study for living donor liver transplant patients
This study looks at living donor liver transplant care and follows patients for about 3 years to see how they do over time. If you had (or are scheduled for) a living donor liver transplant and can be followed long-term, this trial may be able to collect your outcomes.
SeoulAges 19–79 - NCT04742881Recruiting
Laparoscopic colon surgery comparison for bowel tumors or disease
This trial studies a low-impact approach to colon or upper-rectum surgery using small cameras (laparoscopy) to see if it works well and is safe. You may be eligible if you are scheduled for a specific type of colon/rectal operation and can safely be monitored during the study.
BayonneAges 18 years+ - NCT05106322Recruiting
Using a hand scanner to check fat buildup in liver grafts
This study tests whether an on-site, hand-held scanner during surgery can estimate fat-related liver changes in donated liver tissue. It may help surgeons better assess the quality of liver grafts while the transplant is happening.
VillejuifAges 18 years+ - NCT05848609Recruiting
Quality of life study for older adults having robotic colon surgery
This study looks at how older people feel and function after robotic surgery for colorectal cancer. It may help doctors understand what to expect and how to better support quality of life during recovery.
BrusselsAges 70 years+ - NCT04117321Recruiting
Study of mother-to-baby gut germs and baby health
This study looks at how germs in a mother can be passed to her baby and whether that affects the baby’s health. If you join, your baby (and the other parent or legal guardian) may be asked to share consent so researchers can follow the pregnancy and early life.
Hong Kong, Hong KongAges Any age - NCT04282083Recruiting
Registry for adults with confirmed digestive neuroendocrine tumors
This is a registry study that collects medical information from adults with neuroendocrine tumors (NETs) that start in the digestive organs. It helps researchers understand these cancers better and may support future studies.
Rozzano, MilanAges 18 years+ - NCT03819803RecruitingPhase 3
Fecal transplant for gut graft-versus-host disease
This study tests whether restoring healthy gut bacteria using a fecal microbiota transplant can improve steroid-refractory gut graft-versus-host disease (aGvHD) after stem cell transplant. If your gut symptoms are your first episode and your stool bacteria diversity is low, this trial may be an option worth screening for.
Graz, StyriaAges 18–70 - NCT03901235RecruitingPhase 1/Phase 2
Stem cell injections for Crohn’s lesions that won’t heal
This study tests injections of stem cells placed directly into Crohn’s affected tissue. It may help people whose Crohn’s disease lesions have not responded to standard medicines and biologic therapies.
Liège, LiègeAges 18 years+ - NCT04482478Recruiting
Edl treatment trial for functional indigestion symptoms
This trial studies whether EDL medicine can improve symptoms of functional dyspepsia (indigestion) and is safe for people with this condition. You may be asked to complete symptom questionnaires and undergo stomach testing to confirm there is no other cause for your symptoms.
