Testing HOPE treatment to prevent liver cancer return after transplant
This study tests a special way of preserving donated livers, called HOPE, to see if it lowers the chance of liver cancer coming back after a liver transplant. If you have liver cancer and are waiting for a transplant, this trial might be an option for you.
New York, New YorkAges 18 years+ - NCT06718153Recruiting
Using protein tests to diagnose liver cancer types
This trial uses special stains on tumor tissue to find genetic changes in liver cancer cells. It may help doctors better diagnose and classify the type of liver cancer you have.
BolognaAges 18 years+ - NCT06718205RecruitingPhase 2
Nimotuzumab plus immunotherapy and chemo for esophageal cancer
This study tests a new combination of drugs for advanced esophageal cancer. It adds an antibody (nimotuzumab) and an immunotherapy (sintilimab) to standard chemotherapy, aiming to improve how well treatment works.
Zhengzhou, HenanAges 18–75 - NCT06718530Recruiting
Finding early markers for liver cancer in people with chronic liver disease
This study looks for substances in your blood and immune system that could help doctors find liver cancer earlier. It is for people with liver cancer caused by chronic liver problems like hepatitis C, cirrhosis, or scarring.
Aviano, PordenoneAges 18 years+ - NCT06718543RecruitingPhase 2
Short-course radiation with AK112 for rectal cancer before surgery
This trial tests whether combining short-course radiation with an immune therapy drug (AK112) plus chemotherapy before surgery is better than radiation alone for locally advanced rectal cancer. It aims to shrink tumors and improve outcomes without needing stronger treatments later.
Chongqing, Chongqing MunicipalityAges 18–80 - NCT06718738RecruitingPhase 1
IM96 CAR-T for advanced colorectal cancer
This trial tests a new cell therapy called IM96 CAR-T, which targets a protein (GUCY2C) found on tumor cells. It is for people with advanced colorectal or stomach cancer that has not responded to standard treatments.
Beijing, Beijing MunicipalityAges 18–75 - NCT06718842Recruiting
Walking program for children with PKU and fatty liver
This study tests whether a walking program can help children with PKU who also have fatty liver and obesity. It aims to see if regular walking improves liver health and overall fitness.
Dokki, Giza GovernorateAges 9–12 - NCT06719206Recruiting
Reducing sitting time during cancer treatment
This study looks at helping people with breast, prostate, or colorectal cancer who are starting or have recently started treatment (like chemo or radiation) to sit less and move more during their treatment. If you are treated at a hospital in Uppsala or Västerås, Sweden, you may be able to join.
UppsalaAges 18 years+ - NCT06719414Recruiting
Using a special MRI to predict rectal cancer response to pre-surgery therapy
This trial uses a special type of MRI scan (called amide proton transfer-weighted imaging) to look at your rectal cancer before and after chemotherapy and/or radiation. The goal is to see if the scan can predict whether the cancer has completely disappeared by the time of surgery, which could help guide future treatment decisions.
Guangzhou, GuangdongAges Any age - NCT06719778Recruiting
Diet and lifestyle changes for Crohn's disease
