Testing gut bacteria and amino acids to clear hepatitis B surface marker
This study tests whether a combination of a harmless gut bacterium (Bacteroides fragilis) and branched-chain amino acids (BCAAs, which are building blocks of protein) can help your body clear the hepatitis B surface antigen (HBsAg) from your blood. This may mean moving closer to a functional cure for chronic hepatitis B.

Carbon ion radiation for frail patients with pancreatic cancer
This trial tests a precise type of radiation called carbon ion radiotherapy for people with pancreatic cancer who are too frail for surgery or standard chemotherapy. It aims to see if this treatment can help control the cancer with fewer side effects.
SeoulAges 20 years+ - NCT07257653RecruitingPhase 2
Cetuximab beta plus fruquintinib with or without immunotherapy for first-line advanced colorectal cancer
This trial tests a combination of two targeted drugs (cetuximab beta and fruquintinib) with or without an immunotherapy drug for people with a specific type of advanced colorectal cancer that has not been treated before. It aims to see if this approach is safe and effective for those whose tumors have certain genetic markers (RAS and BRAF wild type).
Hangzhou, ZhejiangAges 10–85 - NCT07257835Recruiting
Dupilumab for tough stomach and gut diseases
This trial tests if dupilumab can help people with hard-to-treat stomach ulcers linked to eosinophilic gastrointestinal disorders (EGIDs), where a type of white blood cell builds up in the gut. It may offer a new option for those who haven't gotten better with other treatments.
