This study tests a combination of chemotherapy, radiation therapy, and an immunotherapy drug (anti-PD-1 antibody) for anal squamous cell cancer. The trial enrolls patients at different stages of disease to see if adding immunotherapy improves outcomes.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07556289RecruitingPhase 2
Minimally invasive reflux surgery for Asian patients with severe heartburn
This trial tests a newer, less invasive surgical procedure called TIF (Transoral Incisional Fundoplication) for patients with severe acid reflux and regurgitation that hasn't improved with high-dose medications. The procedure is done through the mouth rather than the abdomen, and researchers will follow patients for 5 years to see if it works and is safe in Asian populations.

Shanghai, Huangpu DistrictAges 18 years+ - NCT07557225Recruiting
New PET Scan for Detecting Multiple Cancer Types
This study tests a new type of PET scan (a specialized imaging test) that may better detect certain cancers by looking for a specific marker found on many tumor types. The scan uses a new tracer called 18F-T2 to help doctors see cancer more clearly.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07557849Recruiting
KRAS Mutation Pancreatic Cancer Treatment Database
This study collects information from patients with pancreatic cancer that has a specific genetic change called a KRAS mutation, who have already received treatment targeting this mutation. Researchers will track outcomes to better understand how these treatments work.
ShanghaiAges Any age - NCT07558447Recruiting
Studying Tiny Particles to Predict Chemotherapy Nerve Damage
This study looks at tiny particles in your blood to understand and potentially predict nerve damage caused by certain chemotherapy drugs. Researchers will monitor you before, during, and after your cancer treatment to see if these particles can help warn doctors about this common side effect.

Chemo-Immunotherapy Plus Radiation vs Standard Treatment for Advanced Esophageal Cancer
This trial compares two treatment approaches for advanced esophageal squamous cell carcinoma (a type of cancer that starts in the lining of the food tube). One group receives chemotherapy combined with an immunotherapy drug before radiation; the other receives chemotherapy and radiation at the same time. The goal is to see which approach works better.
Zunyi, GuizhouAges 18–75 - NCT07559474RecruitingPhase 1
Safety Study of INCB123667 in Adults With Liver Damage
This study tests how a new experimental medicine (INCB123667) works and is tolerated in adults with moderate to severe liver problems. Researchers want to understand how the body processes this drug and whether it's safe in people with liver dysfunction.
Chandler, ArizonaAges 18–80 - NCT07559760RecruitingPhase 2
New combination therapy for advanced colorectal cancer after first treatment
This trial tests a new drug combination for colorectal cancer that has spread to other parts of the body and did not respond to or could not tolerate standard first-line chemotherapy. The goal is to see if this new approach can help shrink the cancer and extend survival.
Changchun, JilinAges 18–75 - NCT07559825Recruiting
Understanding Early-Onset Colorectal Cancer in Younger Patients
This study looks at colorectal cancer in younger patients who wouldn't normally be screened. Researchers want to understand how this cancer develops in people under the typical screening age.
Dallas, TexasAges 35 years+ - NCT07559864RecruitingPhase 2
Regorafenib plus Envafolimab for treatment-resistant gastrointestinal stromal tumors
This study tests a combination of two drugs (regorafenib and envafolimab) for gastrointestinal stromal tumors (a type of stomach/bowel cancer) that have stopped responding to standard treatments. The trial compares this combination to other doctor-selected treatments to see if it slows tumor growth.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07560488RecruitingPhase 2
Immunotherapy and Chemotherapy Combination for Advanced Liver Cancer
This trial tests a combination of four treatments (two immunotherapy drugs, a blood-vessel-blocking drug, and chemotherapy delivered directly to the liver) to shrink unresectable (inoperable) advanced liver cancer and potentially make it removable by surgery. The goal is to help patients who have never had cancer treatment before.
Tianjin, Tianjin MunicipalityAges 18–75 - NCT07560540Recruiting
Nutrition Support Before and After Pancreatic Surgery
This study tests whether a special nutrition plan before and after Whipple surgery (a major operation for pancreatic or bile duct cancer) helps patients recover faster and feel better. Researchers want to see if eating the right nutrients beforehand makes surgery easier on your body.
LahoreAges 18 years+ - NCT07560566RecruitingPhase 2
Preventing Hand-Foot Skin Reaction in Liver Cancer Treatment
This study tests whether a topical anti-inflammatory cream (indomethacin) applied preventively to hands and feet can reduce a painful skin side effect called hand-foot syndrome that occurs in advanced liver cancer patients taking sorafenib. If effective, it could help patients tolerate their cancer medication better.
TaipeiAges 18 years+ - NCT07561060RecruitingPhase 1/Phase 2
Immunotherapy plus chemotherapy for early rectal cancer
This trial tests whether adding an immunotherapy drug called tislelizumab to standard chemotherapy and radiation can help patients with early-stage rectal cancer (cancer within 3 cm of the opening of the rectum) avoid surgery or improve surgery outcomes. The goal is to see if this combination is safe and effective.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07561138Recruiting
Nutrition and Exercise Training Before Liver Transplant
This study tests whether eating better and doing gentle exercise before your liver transplant can help you stay healthier and recover better after surgery. You'll work with a nutrition expert and exercise specialist to prepare your body for transplant.
Athens, AtticaAges 18–70 - NCT07561840Recruiting
Exercise Training After Stomach or Esophagus Cancer Surgery
This study tests whether a guided exercise program helps people recover better after surgery for esophageal or gastric (stomach) cancer. Researchers will track your strength, fitness, and quality of life over time.
Hirakata, OsakaAges 18 years+ - NCT07562490RecruitingPhase 2
Blood Test to Guide Chemotherapy After Colorectal Cancer Surgery
This study tests whether a special blood test (looking for cancer DNA) can help doctors decide if you need chemotherapy after colorectal cancer surgery. The goal is to avoid unnecessary chemotherapy while making sure patients who need it get treated.
ShanghaiAges 18–80 - NCT07562503RecruitingPhase 2
Blood Test to Guide Colorectal Cancer Follow-Up Treatment
This trial tests whether a special blood test that detects cancer DNA can help doctors decide if you need additional chemotherapy after colorectal cancer surgery. The goal is to personalize treatment based on your individual risk rather than giving chemotherapy to everyone.
ShanghaiAges 18–80 - NCT07562659RecruitingPhase 2
Blood Test to Guide Chemotherapy After Colon Cancer Surgery
This study helps doctors decide whether you need chemotherapy after colon cancer surgery by checking for cancer DNA in your blood. The goal is to give chemotherapy only to patients who truly need it, based on what the blood test shows.
ShanghaiAges 18–80 - NCT07562711RecruitingPhase 2
Blood Test to Guide Chemotherapy After Colon Cancer Surgery
This study uses a simple blood test to detect cancer DNA after surgery for early-stage colon cancer. The goal is to help doctors decide whether chemotherapy is truly needed based on the blood test results, rather than giving it to everyone.
ShanghaiAges 18–80 - NCT07563309Recruiting
Testing a new rapid HIV, hepatitis B, and syphilis test
This study evaluates a new rapid blood test that checks for HIV, hepatitis B, and syphilis all at once. Researchers want to make sure the test works well, is easy to use, and gives accurate results.
