Comparing further treatment options for esophageal cancer after chemo-immunotherapy
This trial compares two approaches for people with esophageal cancer that has shrunk or disappeared after initial chemotherapy combined with immunotherapy. It looks at whether adding targeted radiation (DCRT) or surgery is better. The goal is to find the most effective next step for eligible patients.
Tianjin, Tianjin MunicipalityAges 18–75 - NCT07162701Recruiting

TIPS for liver disease with portal hypertension
This trial compares patients who have a rare liver condition (porto-sinusoidal vascular disease) with those who have cirrhosis, to see how a procedure called TIPS (a shunt placed in the liver to reduce blood pressure) works for complications like bleeding, fluid buildup, or blood clots.

RYZ401 for advanced neuroendocrine tumors
This trial tests an experimental drug called RYZ401 for people with advanced neuroendocrine tumors (NETs) that show a certain marker on scans. The drug is designed to target the tumor cells directly and may be a new option for those who have not had a similar type of targeted radiation therapy.
Iowa City, IowaAges 18 years+ - NCT07165210Recruiting
Lymph node spread in esophageal cancer trial
This trial looks at how often a specific lymph node (106TBL) is involved in esophageal squamous cell carcinoma. It may help guide treatment decisions for people who have not had other cancers and whose tumor is in the chest (not the neck).
Shanghai, Shanghai MunicipalityAges 20–85 - NCT07165470Recruiting
Pre-packaged low-residue diet for IBD colonoscopy prep
This study tests whether a ready-to-eat low-residue diet (a diet that leaves very little waste in your colon) helps people with IBD prepare for a colonoscopy. It may make the prep easier and more effective than standard bowel-cleansing drinks.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07165847RecruitingPhase 2
Combination therapy before surgery for gastric cancer
This trial tests a combination of radiation, chemotherapy, and two immunotherapy drugs before surgery for people with resectable gastric or gastroesophageal junction cancer. The goal is to see if this approach can shrink the tumor and improve outcomes.
Chongqing, Other (Non U.s.)Ages 18 years+ - NCT07166406RecruitingPhase 3
Immunotherapy with or without targeted radiation for advanced liver cancer
This trial tests whether adding a precise, targeted form of radiation (called SBRT) to standard immunotherapy (atezolizumab and bevacizumab) can help people with advanced liver cancer that has spread to the blood vessels or outside the liver. You may be asked to participate in one of two treatment groups to see which approach works better.
