Trial for advanced liver cancer with TACE and immunotherapy
This trial is for people with advanced liver cancer (HCC) that has spread outside the liver or into major blood vessels. It tests combining a procedure called TACE with immunotherapy (PD-1/PD-L1 inhibitors) and targeted drugs to see how well they work together.

Comparing partial vs. total omentectomy in gastric cancer surgery
This trial compares removing part or all of the fatty lining of the stomach (omentum) during minimally invasive surgery for a certain stage of gastric cancer. The goal is to see if removing less tissue is as safe and effective.

ctDNA-guided chemo choice for elderly colon cancer patients
This trial tests whether using a ctDNA blood test can help choose the best chemotherapy after colon cancer surgery for people aged 70–80. It aims to make treatment more personalized and reduce side effects.
Hangzhou, ZhejiangAges 70–80 - NCT06609850Recruiting
Comparing TACE plus lenvatinib with or without ablation for recurrent liver cancer
This trial compares two treatments for people whose liver cancer has come back (recurrent intermediate-stage hepatocellular carcinoma). One group gets TACE plus lenvatinib (a targeted therapy), the other gets TACE plus lenvatinib plus ablation (a procedure that destroys tumors with heat or cold). The goal is to see which combination works better.
Beijing, None SelectedAges 18–75 - NCT06609863Recruiting
Triple therapy for large liver cancer tumors
This trial tests combining a special type of chemo delivered directly to the liver (dTACE-HAIC) with two immunotherapy drugs (bevacizumab and atezolizumab) for people with huge liver cancer tumors (10 cm or larger). The goal is to see if this combination can shrink tumors and improve outcomes.
Beijing, None SelectedAges 18–75 - NCT06609876Recruiting
Donafenib after ablation for recurrent liver cancer
This trial tests whether taking the drug donafenib after a procedure called ablation (which destroys liver tumors) can help keep your liver cancer from returning. It is for people whose liver cancer has come back within the past year and who have small, treatable tumors.
Beijing, None SelectedAges 18–75 - NCT06611345Recruiting
Tumor-treating fields with immunotherapy and chemo for bile duct cancer
This trial is testing a new combination of treatments—a wearable device that sends electric fields to the tumor area (tumor-treating fields) plus immunotherapy (durvalumab) and chemotherapy (gemcitabine/cisplatin)—for people with advanced bile duct or gallbladder cancer. It may be an option if you haven't had chemotherapy for advanced disease before.
HefeiAges 18–75 - NCT06612229Recruiting
Bile leaks after surgery for liver echinococcosis
This study looks at how bile leaks (fistulas) happen after surgery for liver echinococcosis, a parasitic infection. It aims to improve understanding and treatment to help patients recover better.
TashkentAges 18 years+ - NCT06612281RecruitingPhase 2
Testing a new screening tool for colorectal cancer in people with negative FIT results
This trial tests a new device called Gixam to see if it can help find colorectal cancer in people who recently had a normal FIT test (a stool test for blood). You may be able to join if you are between 45 and 85 years old and are already scheduled for a routine screening colonoscopy.
Portland, OregonAges 45–85 - NCT06613165Recruiting
Short vs long treatment for stage II-III rectal cancer with dMMR
This trial tests how long you need a PD-1 immunotherapy before surgery for a specific type of rectal cancer (dMMR/MSI-H). It looks at whether a shorter or longer course works best. This could mean fewer side effects and a quicker path to surgery.
Xi'an, ShaanxiAges 18–80 - NCT06613438Recruiting
New wearable device for GERD symptoms
This study tests a new wearable device (eGERD) that aims to reduce symptoms of GERD (heartburn and regurgitation). The trial will check if the device is safe and works well without needing medication.
Chicago, IllinoisAges 22–75 - NCT06613581Recruiting
Home-based follow-up after colorectal cancer surgery
This trial tests whether patients can do their follow-up from home after surgery for colorectal cancer. It uses a smartphone app instead of hospital visits, aiming to make surveillance easier and less stressful.
Breda, North BrabantAges 21 years+ - NCT06614647Recruiting
Digital follow-up for colorectal cancer survivors
This trial tests a smartphone-based follow-up program for people who have been treated for early-stage colorectal cancer. The goal is to see if a digital, need-based care guide can replace standard follow-up visits.
Herning, Central JutlandAges 18 years+ - NCT06614738Recruiting

AMB-05X for colorectal cancer with ctDNA after treatment
This trial tests a drug called AMB-05X for people with colorectal cancer who have completed all intended treatments and show no signs of cancer on scans, but still have cancer DNA (ctDNA) in their blood. The goal is to see if AMB-05X can eliminate this remaining cancer DNA and prevent the cancer from coming back.

UtrechtAges 18 years+ - NCT06619106Recruiting
Screening tool for minimal hepatic encephalopathy
This study tests a new cognitive tool to quickly and reliably detect minimal hepatic encephalopathy, a subtle brain change that can occur in people with liver disease. If you have a liver condition like fibrosis or cirrhosis and are already scheduled for a full evaluation (neuropsychological tests, MRI, EEG, and blood ammonia), this tool could help simplify future screening.
