Sydney, New South WalesAges 18 years+ - NCT06200259Recruiting
Reducing Bowel Side Effects in Prostate Cancer Proton Therapy
This study tests a way to reduce stomach and bowel side effects of proton therapy for prostate cancer. It uses special software to place the proton beam more carefully, which may protect nearby organs.
Knoxville, TennesseeAges 18 years+ - NCT06223230Recruiting
Supportive care trial for advanced digestive cancers
This trial tests if adding nutrition counseling, psychological support, and better nausea control to standard cancer treatment can help people with advanced digestive cancers live longer and feel better.
Wuhan, HubeiAges 18–75 - NCT07264998Recruiting
Gut bacteria study in breast cancer patients on Abemaciclib
This study looks at how gut bacteria changes in people taking Abemaciclib (a breast cancer drug) and whether that relates to diarrhea. It may help find ways to prevent or manage this side effect.
Wuhan, HubeiAges 18–75 - NCT06523582Recruiting
Genetic study of neuroendocrine tumors in Mexican patients
This study aims to find genetic causes of neuroendocrine tumors in Mexican patients. By understanding your DNA, researchers hope to improve diagnosis and treatment for people with these rare conditions.
Mexico City, Mexico CityAges 18 years+ - NCT07001592RecruitingPhase 1
Injection of a modified virus for advanced GI and peritoneal cancers
This trial tests a modified virus injected directly into tumors to treat metastatic gastrointestinal and peritoneal cancers. It aims to see if this approach can shrink tumors or slow their growth.
Pittsburgh, PennsylvaniaAges 18–69 - NCT06081647Recruiting
Testing a new airway device for endoscopy
This trial tests a special mouth-and-throat device designed to help you breathe easier during a routine endoscopy or colonoscopy. If you are a generally healthy adult scheduled for one of these procedures, you may be able to join.

Belzutifan for cancers linked to VHL or HIF-2α changes
This Phase 2 study tests belzutifan (MK-6482) to treat certain advanced cancers caused by specific gene or disease changes, including VHL-related tumors and HIF-2α related tumors. It may help shrink tumors or slow their growth in people whose cancer matches these genetic or disease patterns.
Los Angeles, CaliforniaAges 12 years+ - NCT06805825RecruitingPhase 1
Study of NN3201 for advanced cancers with c-Kit
This trial tests a new drug, NN3201, that targets a protein called c-Kit found on some cancer cells.

Common questions
- Are there clinical trials for gastrointestinal cancer?
- Yes. Clin2 currently lists 161 recruiting gastrointestinal cancer studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a gastrointestinal cancer trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a gastrointestinal cancer trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
