Radiation, immunotherapy, and targeted therapy before surgery for liver cancer with portal vein tumor thrombus
This trial tests whether combining radiation (IMRT) with two drugs—camrelizumab (an immunotherapy) and apatinib (a targeted therapy)—before surgery can help people with liver cancer that has spread to the main blood vessel of the liver (portal vein). The goal is to shrink the tumor and improve surgical outcomes.

Surgery for pancreatic cancer with limited liver spread after chemo
This trial is for people with pancreatic cancer that has spread to the liver (3 spots or fewer). It tests whether removing both the original tumor and the liver spots after a specific chemotherapy (FOLFIRINOX) can be helpful. You may be eligible if the chemo shrinks the tumors enough and you are healthy enough for surgery.

Testing a live tumor test for immune therapy response
This trial uses a special test on live tumor samples to see if it can predict how well immune checkpoint inhibitors (a type of immunotherapy) will work for different cancers. It may help doctors choose the best treatment for you.
Phoenix, ArizonaAges 18 years+ - NCT06349590RecruitingPhase 1/Phase 2
Diet before colon cancer surgery to reduce recurrence
This trial tests whether a specific diet before colon cancer surgery can change the bacteria in your gut to help prevent the cancer from coming back or spreading. Patients who are eligible will follow the diet for a short time before their operation.

Study of three drugs for liver cancer not yet treated
This trial is testing a combination of three drugs (HLX10, HLX04, and HLX53) to find the best dose and see if they help people with advanced liver cancer who have not had systemic treatment before. The goal is to shrink tumors and improve survival.
ShanghaiAges 18 years+ - NCT06350370Recruiting
Colorectal Cancer Outcomes with NOSES Surgery
This study tracks patients with colon or rectal cancer who have a special type of surgery called natural orifice specimen extraction surgery (NOSES). The goal is to see how well patients do short-term and long-term after this procedure.
Beijing, Beijing MunicipalityAges 18–75 - NCT06351124RecruitingPhase 1/Phase 2
Beta-hydroxybutyrate for active Crohn's disease when starting new therapy
This study tests whether a natural substance called beta-hydroxybutyrate (BHB) can help treat active Crohn's disease when you start a new prescription therapy. It aims to see if adding BHB is safe and practical.
Austin, TexasAges 18 years+ - NCT06351202Recruiting
Abdominal massage for feeding issues in preemies
This study tests whether gentle tummy massage can help premature babies in the NICU who have trouble digesting feedings. If your baby qualifies, they will receive daily massages to see if it improves feeding and comfort.
Clermont-FerrandAges 3 days–2 months - NCT06351475Recruiting
Albumin during surgery for advanced cancer in the abdomen
This trial tests whether adding a protein called albumin to standard fluids given during surgery helps patients with advanced cancer in the abdomen (from the ovaries, uterus, or digestive system) recover better. You would receive either the usual fluids or fluids plus albumin during your operation.
MontpellierAges 18–80 - NCT06353126RecruitingPhase 4
Chemoembolization before liver transplant for liver cancer
This trial tests whether using chemotherapy beads delivered directly to the liver (DEB-TACE) before a living donor liver transplant improves outcomes for people with liver cancer. If you have a tumor in the right side of the liver that fits certain size and number limits, and you are already scheduled for a transplant, this study may be an option.
