Testing tumor tissue to understand and predict colorectal cancer response
This study looks at tissue samples from people with colorectal cancer to better understand tumor features and how they may respond to treatment. If you have colorectal cancer, the trial may help researchers match future treatments more effectively.
GothenburgAges 18 years+ - NCT06118762RecruitingPhase 4
Study of fruquintinib plus raltitrexed for advanced colorectal cancer
This trial tests two drugs, fruquintinib and raltitrexed, for people with metastatic colorectal cancer that has stopped responding to or is no longer tolerable after standard treatments like fluorouracil, oxaliplatin, and irinotecan. The goal is to see if this combination can help shrink or control the cancer.

Chemoimmunotherapy and radiation before surgery for limited spread stomach cancer
This trial tests combining chemotherapy, immunotherapy, and radiation before surgery for stomach or gastroesophageal junction cancer that has spread to a limited number of sites. The goal is to see if this approach can improve outcomes by shrinking tumors before they are removed.
ShanghaiAges 18–75 - NCT06122493RecruitingPhase 2
Better treatment for advanced esophageal cancer
This trial tests a new treatment plan for people with advanced esophageal squamous cell carcinoma that has spread to lymph nodes but not to other organs. It aims to find the best way to treat this cancer using radiation and other therapies.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT04446832Recruiting
Vaccine study for people waiting for liver transplant
This study tests a vaccine strategy for people who are being evaluated and waiting for a liver transplant. The goal is to see how well the immune system responds and how the results are interpreted before transplant.
LyonAges 18 years+ - NCT06126406RecruitingPhase 1
CEA-targeting CAR-T cell therapy for advanced solid tumors
This trial tests a new immune cell therapy (CAR-T) designed to attack cancer cells that make a protein called CEA. It may be an option for people with advanced colorectal, esophageal, gastric, or pancreatic cancer who have already tried at least two standard treatments.
Wuhu, AnhuiAges 18 years+ - NCT04578340Recruiting
Follow-up after hernia repair with mesh
This study looks at long-term outcomes after abdominal hernia surgery where a mesh patch was used. It may help doctors understand what to expect long-term and how well mesh repair works over time.
Evanston, IllinoisAges 18 years+ - NCT04745403RecruitingPhase 1
Trial of redirected HBV-targeting T cells for liver cancer
This Phase 1 study tests a lab-made immune cell treatment that targets hepatitis B (HBV)–related liver cancer. It may help by directing the body’s immune system to attack the cancer, while carefully checking safety.
SingaporeAges 21–75 - NCT04754672Recruiting
Exercise training to improve outcomes in advanced colon cancer
This trial studies whether supervised exercise—either aerobic fitness training or muscle-strength training—can improve outcomes for people with metastatic colorectal cancer. It compares which approach is most helpful and checks whether it’s safe during first-line chemotherapy.
's-HertogenboschAges 18 years+ - NCT05938439Recruiting
Testing a magnetic device for Candy Cane Syndrome
This trial studies how well a small magnetic device works to relieve problems caused by Candy Cane Syndrome, such as pain, nausea, vomiting, or reflux-like symptoms. It will also check whether the device is safe for your anatomy and overall health.
BrusselsAges 18–85 - NCT06121089Recruiting
Surgery for early-stage cecal cancer
This trial is testing different surgical approaches for people with cecal cancer that hasn't spread. The goal is to find the best treatment option for patients whose tumors are at a stage where surgery can be curative.
MoscowAges 18 years+ - NCT05960955RecruitingPhase 2
Testing immunotherapy plus chemo around the time of gastric surgery
This study tests whether adding cadonilimab (and possibly AK117) to chemotherapy can improve outcomes for people with resectable stomach or stomach–esophagus cancer. It aims to see if this combination works better than chemotherapy alone, while still being safe around surgery.
TianjinAges 18–75 - NCT06136845Recruiting
Esophageal cancer microbiome and leak after surgery
This study looks at bacteria in esophageal cancer tumors and whether certain bacteria are linked to leaks that can happen after surgery to remove the esophagus. It may help doctors understand how to prevent these leaks in the future.
HaifaAges 18–85 - NCT06136949Recruiting
STARD3 study for colorectal cancer patients
This study looks at a marker called STARD3 in colorectal cancer to understand its role and potential for targeted treatment. It may help find new ways to treat the disease.
Aviano, PordenoneAges 18 years+ - NCT02988921Recruiting
MRI and CT planning for esophagus or stomach-junction cancer treatment
This study checks whether MRI and CT scans can better measure how esophageal or stomach-junction tumors respond during chemoradiotherapy and help doctors map the exact treatment area. It may help improve targeting while you receive standard treatment.
BeijingAges 18 years+ - NCT06017284RecruitingPhase 3
Thalidomide for nausea in pancreatic cancer patients
This trial tests whether adding thalidomide to standard chemotherapy can help reduce nausea and vomiting in people with advanced pancreatic cancer. It is for patients who have not yet received any cancer treatment.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT02306382Recruiting
Study for diagnosing and treating perianal abscesses with surgery
This study focuses on people 18 and older who have a perianal abscess that needs surgical treatment. It aims to improve how these abscesses are diagnosed and managed, including care around surgery.
Umeå, County of Vasterbotten §Ages 18 years+ - NCT02270476Recruiting
Study of how cystic fibrosis lung disease changes over time
This observational study follows children newly diagnosed with cystic fibrosis to understand how their lung disease develops. It may help doctors better predict disease course and choose the right timing for care.
Heidelberg, Baden-WurttembergAges Any age - NCT05561504Recruiting
Study of stomach bacteria resistance in adults
This study looks at how common a stomach bacteria infection is and which antibiotics still work. You may help researchers by providing consent for related study participation and sample tracking.
