Van, VanAges 60 years+ - NCT07815392Recruiting
Frailty and recovery after gastrointestinal cancer surgery
This study looks at how frailty, or overall physical weakness, affects recovery after surgery for gastrointestinal cancer in people aged 60 and older. The findings may help doctors better prepare patients for surgery and improve their recovery.

Study of Amimaitosai plus steroids for gut graft-versus-host disease
This study tests whether adding an investigational drug called Amimaitosai to standard steroids helps control gut symptoms caused by graft-versus-host disease after a stem cell transplant. It may offer a new option to reduce these symptoms and improve recovery.
Beijing, Beijing MunicipalityAges 14 years+ - NCT05219903Recruiting
Study of children with eosinophilic gut disorders
This study looks at children ages 0–18 with eosinophilic gut disorders (EGIDs) to better understand these conditions and how they are managed. It may help doctors improve care by comparing real-world information from patients followed at participating hospitals.
PaviaAges birth–18 years - 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+ - NCT07779772Recruiting
Diet changes for children with eosinophilic gut disorders
This trial compares different elimination diets to see which one best reduces inflammation in children with eosinophilic gastrointestinal disorders. Your child might have fewer symptoms and a better outcome if the right diet is found.
Adana, SarıcamAges 2–18 - NCT07782203Recruiting
Tissue bank for digestive conditions and cancers
This study collects tissue samples from people with digestive conditions or cancers during routine procedures like endoscopy or surgery. The samples are used to build models for research, helping researchers better understand these diseases and develop new treatments.
StrasbourgAges 18 years+ - NCT07763652RecruitingPhase 1
Study of BL-ARC002 for advanced gastrointestinal and other solid tumors
This trial tests an investigational drug called BL-ARC002 for people with advanced or metastatic cancers of the esophagus, stomach, colon, rectum, or other solid tumors. The goal is to see if it is safe and effective in treating these cancers.

Remimazolam with oliceridine for sedation in older adults during GI endoscopy
This trial tests two medicines, remimazolam (a sedative) and oliceridine (a pain reliever), to see if they work well together for sedation during a painless gastrointestinal (GI) endoscopy in people aged 65 to 80. It aims to find a safe and effective option for older adults.

- Yes. Clin2 currently lists 469 recruiting gastrointestinal 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 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 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.
