ITGA6-targeted dye for liver cancer surgery guidance
This trial uses a special dye that lights up during surgery to help doctors see and remove liver cancer cells that have a specific protein (ITGA6). It aims to make surgery more precise and effective.

Charleston, South CarolinaAges 18–75 - NCT06205472RecruitingPhase 2
Radiation after liver cancer surgery with narrow margins
This trial tests whether adding a type of radiation (SIB radiotherapy) after liver cancer surgery can improve outcomes for patients whose tumors were removed with very narrow clear margins (less than 1 cm). It may help reduce the chance of cancer coming back in the remaining liver.
BeijingAges 18 years+ - NCT06205849RecruitingPhase 1
Testing a new drug and procedure for advanced pancreatic cancer
This trial tests a new drug called mitazalimab injected directly into the tumor, combined with a special electrical procedure that kills cancer cells. It is for people whose pancreatic cancer has not spread but cannot be removed by surgery.
La Jolla, CaliforniaAges 18 years+ - NCT06205836RecruitingPhase 2
Cemiplimab with or without Fianlimab for MSI-H Colorectal Cancer in Older Patients
This trial tests a new immunotherapy combination for older patients with a specific type of colorectal cancer that has not been treated before. The goal is to see if these drugs can help the immune system fight the cancer without needing surgery or standard chemotherapy.
Baltimore, MarylandAges 18 years+ - NCT06206616Recruiting
Liver fat in children with celiac disease
This study looks at whether children with celiac disease have fat buildup in the liver. It aims to help doctors understand and manage this condition better.
Palermo, PalermoAges 1–14 - NCT06206707Recruiting
FMT for Diarrhea and Colitis After Immunotherapy
This trial tests whether a treatment called fecal microbiota transplant (FMT) — transferring healthy gut bacteria — can help relieve diarrhea and colitis caused by immunotherapy drugs. If you have melanoma or kidney cancer and are experiencing diarrhea after immunotherapy, this study may offer a new option.
Aarhus NAges 18 years+ - NCT06207656RecruitingPhase 2
Targeted therapy for BRAF V600E mutated colorectal cancer
This trial tests if combining three targeted drugs (cetuximab, encorafenib, and binimetinib) before surgery can shrink or control cancer in people with a specific BRAF V600E mutation and a stable (MSS) tumor. It focuses on colorectal cancer that is either already able to be removed or could become removable with treatment.
MadridAges 18 years+ - NCT06207981RecruitingPhase 3
Comparing two treatment plans for advanced anal cancer
This trial tests if giving chemotherapy before standard chemoradiation works better than standard chemoradiation alone for people with locally advanced anal cancer that has not spread. It aims to improve treatment outcomes.
AgenAges 18 years+ - NCT06208371RecruitingPhase 3
Local treatment vs. chemo for colorectal cancer with many liver spots
This trial tests whether treating all liver tumors with surgery, ablation, or radiation is better than continuing standard chemotherapy for people with colorectal cancer that has spread only to the liver. It's for those whose liver tumors have been controlled by initial chemotherapy and are considered removable.
Guangzhou, GuangdongAges 18 years+ - NCT06208397Recruiting
MRI study to understand liver tumor growth patterns
This trial uses MRI scans to study how colorectal cancer that has spread to the liver grows. It may help doctors choose better treatments.
Shenyang, LiaoningAges 18–80 - NCT06209099Recruiting
Organ preservation first for low-risk rectal cancer
This trial tests a strategy to avoid surgery by using watchful waiting after initial treatment for early-stage rectal cancer. It may help patients keep their rectum and avoid a permanent colostomy.
Beijing, Haidian DistrictAges 18–85 - NCT06210178Recruiting
New way to measure liver pressure without needles
This study tests a new, non-invasive method (using an MRI) to estimate pressure in the veins of the liver. If successful, it could replace the need for a catheter procedure for patients being evaluated for a liver transplant.
Leiden, South HollandAges 18–75 - NCT06211062RecruitingPhase 2
Probiotics for chronic fatigue syndrome with IBS
This study tests whether a specific mix of probiotics can help people with chronic fatigue syndrome (ME/CFS) who also have irritable bowel syndrome (IBS). It's a small trial to see if improving gut health can ease symptoms.
Fort Lauderdale, FloridaAges 45–70 - NCT06211400Recruiting
Vibration Exercise for Crohn's Disease Response
This study tests whether gentle whole-body vibration exercise can help people with mild to moderate Crohn's disease feel better. You will do short vibration sessions at a research center over several weeks.
Hatfield, UKAges 18–65 - NCT06211556Recruiting
Reducing liver fat in type 2 diabetes
This study tests whether reducing liver fat can improve health in people with type 2 diabetes. It looks at the effects of a specific medication combined with exercise, tailored for those who are not very active.
Copenhagen, Capital RegionAges 30–70 - NCT06211868Recruiting
Early heart disease risk study for adults 40-70
This study looks at whether changing your immune system, fats, and metabolism can lower your risk of early heart disease. It is for people with an intermediate to high risk score but who have not yet had a heart attack or stroke.
SingaporeAges 40–70 - NCT06213857RecruitingPhase 2
Silymarin for ulcerative colitis
This study tests whether silymarin (an extract from milk thistle) can help treat ulcerative colitis when added to your usual treatment. It may reduce inflammation and oxidative stress in the colon.
AsyutAges 18–65 - NCT06214572RecruitingPhase 2/Phase 3
Radiation Therapy for Advanced Gallbladder Cancer
This trial tests a type of radiation therapy for people with advanced gallbladder cancer that cannot be removed by surgery. It is for those whose cancer has not spread to other parts of the body and has stayed stable or improved after initial chemotherapy.
Mumbai, MaharashtraAges 18 years+ - NCT06214988Recruiting
Temporary stoma or not for rectal cancer surgery
This trial tests whether a temporary stoma (a bag on the belly) can be safely avoided in some people having rectal cancer surgery. The goal is to see if it's okay to skip the stoma in those with a low risk of complications.
MalmöAges 18 years+ - NCT06215040Recruiting
Treatment for silent common bile duct stones
This trial is for people who have a stone in the main bile duct (the tube that carries bile from the liver) but do not have symptoms like fever or belly pain. It tests how well different treatments work for these ‘silent’ stones.
Daegu, Gyungsangbok-doAges 18–85 - NCT06215222Recruiting
Studying gut bacteria in IBS and digestive issues
This study uses a tiny capsule to collect samples from your small intestine to learn about gut bacteria in people with IBS or other functional gut disorders. It could help researchers understand what causes digestive symptoms.

Safety study of IMM-H014 in healthy adults

Changchun, JilinAges 18–45 - NCT06216470RecruitingPhase 2
Testing an antibody treatment for chronic hepatitis B
This study tests a new antibody treatment (VIR-3434) for chronic hepatitis B. It aims to see if the antibody can help your immune system control the virus, potentially allowing you to stop your current antiviral medication later.
