This trial studies toripalimab (an immune system medicine) plus FLOT chemotherapy in people with stomach cancer that has grown locally but hasn’t spread to distant organs. It aims to improve control of the cancer and help more people have their tumors fully treated.
Zhengzhou, HenanAges 18–70 - NCT06446050RecruitingEarly Phase 1
Modified stem cells for advanced colorectal cancer
This trial tests a new treatment using special stem cells (modified to boost your immune system) for people with advanced colorectal cancer. It is for patients who are 18 or younger and whose cancer has not responded to or cannot be treated with standard therapies.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06446440Recruiting
Keyhole surgery for scar tissue blocking the intestine
This study tests a keyhole surgery (laparoscopy) to cut away scar tissue (adhesiolysis) that is blocking the intestine. It is for people whose blockage is caused by scar tissue and who have not gotten better with non-surgical care.
AsyutAges 18 years+ - NCT06449833RecruitingPhase 4
Henagliflozin for liver fat in diabetes and fatty liver
This study tests whether a medicine called henagliflozin can help reduce fat in the liver for people with type 2 diabetes and non-alcoholic fatty liver disease. It may help improve liver health and blood sugar control at the same time.
Guangzhou, GuangdongAges 18–75 - NCT06449937Recruiting
Local liver treatment for colorectal cancer that has spread
This trial tests whether treating liver tumors with surgery or ablation can help people whose colorectal cancer has spread to the liver and other organs. It may be an option if you've had only 1 or 2 types of chemotherapy and your non-liver metastases are stable.
Chuzhou, AnhuiAges 18–80 - NCT06451432Recruiting
Laparoscopic vs. open hernia repair in children
This trial compares two ways to repair a hernia in children: laparoscopic surgery (using a small camera) and open surgery (a traditional cut). It aims to see which is more effective and cost-effective.
Veldhoven, North BrabantAges birth–16 years - NCT06452966Recruiting
Traditional Chinese medicine for organ failure in ICU
This trial is studying whether adding traditional Chinese medicine (TCM) to standard care can help patients in the surgical ICU recover from organ failure. It looks at how TCM might support your body's organs during critical illness.
TaichungAges 20 years+ - NCT06451393Recruiting
AI predicts stomach cancer response to chemo
This trial tests a computer-based model that uses CT scans, endoscopic images, and biopsy tissue to predict how well stomach cancer will respond to chemotherapy given before surgery. The goal is to help doctors choose the best treatment for each patient.
Guangzhou, GuangdongAges 20–90 - NCT06451211RecruitingPhase 2
Immuno-chemo before surgery for thick or large stomach cancers
This trial tests a combination of immunotherapy and chemotherapy given before surgery to shrink stomach cancers that are particularly thick or large. It aims to see if this approach can make these hard-to-treat tumors easier to remove and improve outcomes.
Guangzhou, GuangdongAges 18–75 - NCT04678583Recruiting
Surgery plan for RAS-mutant colon cancer liver metastases
This trial studies an approach to surgically removing liver metastases from colon (or rectal) cancer that has an RAS gene mutation (KRAS or NRAS). If you qualify, you would be evaluated for whether a “complete” (R0) liver operation is planned and technically possible, aiming to improve cancer control by how the liver is cut.
Mannheim, Baden-WurttembergAges 18 years+ - NCT06065150Recruiting
Early surgery vs 3-day waiting for bowel blockage
This trial compares two approaches for a sudden blockage in the small intestine caused by scar tissue: having surgery right away versus waiting up to three days with non-surgical care. It aims to see which approach leads to better outcomes, so you and your doctor can make a more informed choice.
AmiensAges 18 years+ - NCT06284577Recruiting
Quality of life and gut health in children with cystic fibrosis
This study looks at how a drug called ETI (a combination of three medicines) affects the quality of life and gut health of children with cystic fibrosis. If you or your child has the right type of CF and is between 2 and 18 years old, this trial may help us understand how treatment improves daily life and digestion.

Radiotherapy for metastatic esophageal cancer responding to immunotherapy
This trial tests whether adding radiotherapy can help people with metastatic esophageal cancer that has already responded well to initial treatment with immunotherapy and chemotherapy. It may offer a way to improve outcomes for those whose cancer has not progressed after 2-4 cycles of first-line treatment.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07840677RecruitingPhase 2
Cholesterol-lowering drug plus chemoimmunotherapy before surgery for advanced colon cancer
This study tests a new treatment combination for people with locally advanced colon cancer that has not spread. It combines a cholesterol-lowering drug (tafolecimab) with standard chemotherapy and immunotherapy before surgery, to see if it helps shrink the tumor and improve outcomes.
Chongqing, Chongqing MunicipalityAges 18–80 - NCT07835087Recruiting
Guided removal of sentinel lymph nodes in early stomach cancer
This trial tests a new image-guided method to find and remove sentinel lymph nodes (the first nodes where cancer might spread) in people with early stomach cancer. The goal is to precisely remove only the affected lymph nodes during surgery, which might mean a less extensive operation and fewer side effects.
