Hefei, AnhuiAges 18–80 - NCT05939661RecruitingPhase 2
Total treatment before surgery for early rectal cancer
This Phase 2 study tests a “total neoadjuvant” approach, meaning you receive cancer treatment before surgery, to improve safety and effectiveness for rectal cancer. It may help by shrinking the tumor and planning a more effective operation, while researchers carefully track side effects.
OsakaAges 18 years+ - NCT05443841Recruiting
Pleural lavage test to guide surgery in resectable esophageal cancer
This trial studies whether washing fluid from around the lungs (pleural lavage) can show cancer cells and help predict outcomes for people with operable esophageal cancer. It may add useful information before surgery to support better treatment decisions.
Hefei, AnhuiAges Any age - NCT05952661Recruiting
Testing immune treatment after esophageal cancer therapy
This trial looks at how best to add an immunotherapy “extra” before, during, and after standard chemoradiation for stage II–III esophageal squamous cell cancer that can’t be operated on. It may help reduce cancer that remains after treatment by targeting immune cells.
Shijiazhuang, HebeiAges 18–75 - NCT02060565Recruiting
Test noninvasive scans to diagnose chronic liver disease
This study looks at how well noninvasive tests (tests that don’t require surgery, like scans and blood-based measurements) can diagnose chronic liver disease in people with certain liver conditions. It may help doctors choose better, less invasive ways to identify the type and stage of liver problems.
PessacAges 18 years+ - NCT05954897RecruitingPhase 2
Lenvatinib plus tislelizumab with HAIC for advanced liver cancer
This Phase 2 study tests whether combining three treatments—lenvatinib, tislelizumab, and a liver-directed chemotherapy approach (HAIC)—can shrink advanced hepatocellular carcinoma. It may help people whose cancer is stage C and hasn’t been treated before.
Guangzhou, GuangdongAges 18 years+ - NCT05729646RecruitingPhase 2
Pre-surgery chemotherapy with toripalimab for dMMR stomach cancer
This trial studies whether adding toripalimab (an immune therapy) to chemotherapy before and around surgery can improve outcomes for people with certain mismatch repair–deficient stomach cancers. It mainly targets tumors that are dMMR and not HER2-positive.
Hangzhou, ZhejiangAges 18–80 - NCT05734300Recruiting
Surgery study for older adults with early colon cancer
This study looks at how well a planned surgery approach works for people age 75 and older with early-stage colon cancer. It may help improve outcomes by selecting the right patients for a specific colon operation plan.
Copenhagen, HerlevAges 65 years+ - NCT05962190Recruiting
Short-term extra fat intake to study liver metabolism
This study tests what happens to the liver and fat metabolism when you eat extra fat for a short time. It may help researchers understand how diet affects liver function and metabolism in otherwise stable adults.
OxfordAges 18–65 - NCT05984342RecruitingPhase 1
Tislelizumab plus chemo after surgery for lymph node-positive esophageal cancer
This trial tests whether adding the immunotherapy drug tislelizumab to standard chemotherapy after surgery can help prevent esophageal cancer from coming back. It is for people whose cancer had spread to lymph nodes at the time of surgery.
Shantou, GuangdongAges 18–70 - NCT05869474Recruiting
Iodine seed implant plus chemotherapy for metastatic pancreatic cancer
This trial studies whether placing iodine-125 radioactive seeds during a procedure, along with chemotherapy, can improve outcomes for people with pancreatic cancer that has spread to other organs. It aims to test a treatment that targets the tumor area while systemic chemotherapy works throughout the body.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT05914389RecruitingPhase 2
Immunotherapy plus chemotherapy before surgery for colon cancer
This Phase 2 trial studies giving chemotherapy plus immune therapy before surgery for certain colon cancers that do not have mismatch repair defects (MSS/pMMR). The goal is to shrink and control the tumor and improve outcomes compared with standard approaches.
Hangzhou, ZhejiangAges 18–75 - NCT05984485RecruitingPhase 3
Surgery vs chemo before surgery for low-risk rectal cancer
This trial compares two approaches for low-risk locally advanced rectal cancer: going straight to surgery (TME) versus receiving chemotherapy before surgery. The goal is to see if upfront surgery works just as well, sparing patients from chemotherapy side effects.
Chongqing, Chongqing MunicipalityAges 18–75 - NCT05984576Recruiting
Chemo and radiation for recurrent rectal cancer after prior pelvic radiation
This study looks at combining total neoadjuvant therapy (chemotherapy and radiation) for rectal cancer that has come back in the pelvis after earlier radiation. It aims to see if this treatment approach can help control the disease and improve outcomes in patients with limited spread that can potentially be removed or treated.
RomeAges 18 years+ - NCT05988879Recruiting
Functional cure for hepatitis B in HIV/HBV co-infection

SeoulAges 18 years+ - NCT06009744Recruiting
Vitamin C and zinc for treating bowel leaks
This trial tests whether high doses of vitamin C and zinc can help heal a type of bowel leak (enterocutaneous fistula) in people who need nutrition through a vein. It might help reduce the output from the fistula and speed up recovery.
Mexico City, Mexico CityAges 18–70 - NCT05046483Recruiting
Blood sugar study after a new heart attack
