Pulsed low-dose radiation vs standard chemoradiation for esophageal cancer
This trial compares a new way of giving radiation (in short, pulsed low-dose bursts) to the standard method, both combined with chemotherapy, for people with esophageal cancer. It aims to see if the pulsed approach is safer and equally effective.
Milwaukee, WisconsinAges 18 years+ - NCT06907342RecruitingPhase 2
Personalized chemo selection for advanced colorectal cancer
This trial tests whether a functional test on a tumor biopsy can help choose the best first chemotherapy regimen (FOLFOX or FOLFIRI) for people with metastatic colorectal cancer. It aims to improve outcomes by matching treatment to each person's unique tumor biology.

Comparing two drugs for Dientamoeba fragilis stomach issues
This trial tests if paromomycin or metronidazole works better for adults with ongoing stomach problems caused by a parasite called Dientamoeba fragilis. These symptoms (pain, bloating, diarrhea) must have lasted more than a month, and no other cause has been found.
Ramat Gan, IsraelAges 18 years+ - NCT06907602RecruitingPhase 2/Phase 3
Optimizing treatment before surgery for advanced esophageal cancer
This trial tests different combinations of treatments given before surgery for a type of esophageal cancer called squamous cell carcinoma. It aims to find the best approach to shrink the tumor and improve outcomes for patients whose cancer has not spread to distant organs.

Helping Detroit cancer survivors with social needs
This study looks at how social needs (like finding enough food) affect cancer survivors in the Detroit area. If you join, researchers will work to connect you with resources that might help.
Detroit, MichiganAges 18 years+ - NCT06908746Recruiting
Citrate Anticoagulation in Dialysis for Liver and Kidney Failure
This trial looks at whether a blood thinner called citrate is safe and effective in patients who have both kidney and liver failure while on continuous dialysis in the ICU. It may help guide treatment for people with serious organ problems.
Edegem, AntwerpAges 18 years+ - NCT06908785Recruiting
Blood test to predict bleeding risk after procedures in cirrhosis
This trial is testing if a special blood test called ROTEM can help doctors predict the risk of bleeding after high-risk procedures in people with cirrhosis. It aims to improve safety and guide treatment decisions.
Santander, CantabriaAges 18–65 - NCT06908798Recruiting
Using a stool test to predict varices in cirrhosis
This study checks if a simple stool test (fecal calprotectin) can help predict the presence of enlarged veins in the esophagus (varices) in people with cirrhosis. If successful, this could offer a non-invasive way to screen for this serious complication.
Tanta, GharbyeaAges 18 years+ - NCT06909188Recruiting
Helicobacter infection in bile duct cancer patients
This study looks for links between Helicobacter bacteria and cancers of the bile ducts and gallbladder. It compares patients with bile duct cancer, people having gallbladder surgery for non-cancer reasons, and healthy liver donors.
New Delhi, National Capital Territory of DelhiAges 18 years+ - NCT06910553Recruiting
IBD Pregnancy Registry for mothers
This study is a registry that collects information from pregnant people with inflammatory bowel disease. By joining, you help researchers understand how IBD and treatments affect pregnancy and baby health.
Wilmington, North CarolinaAges 18–50 - NCT06911255RecruitingPhase 1/Phase 2
Testing two immunotherapy drugs with chemoembolization for liver cancer
This trial tests whether adding two immunotherapy drugs (tremelimumab and durvalumab) to a standard liver cancer treatment called TACE can help people with liver cancer that cannot be removed by surgery. TACE uses tiny particles to block the blood supply to the tumor and delivers chemotherapy directly to the liver.
SeoulAges 19 years+ - NCT06911684RecruitingPhase 2
Combination therapy before surgery for rectal cancer
This trial tests a combination of radiation, two immunotherapy drugs (iparomlimab and tuvonralimab), a targeted therapy (regorafenib), and chemotherapy (CAPOX) given before surgery for locally advanced rectal cancer. The goal is to see if this approach can shrink the tumor and improve outcomes for people whose tumors have normal mismatch repair proteins (pMMR/MSS).
Guangzhou, GuangdongAges 18–75 - NCT06911749Recruiting
Using MSOT and MRI to measure bowel transit in children
This trial tests whether two imaging techniques, MSOT and MRI, can safely and non-invasively measure how long it takes for food to move through the bowels in children with chronic constipation or other bowel emptying problems. It may help doctors better understand and treat these conditions.
Erlangen, BavariaAges 1 year+ - NCT06911970Recruiting
