Los Angeles, CaliforniaAges 18 years+ - NCT07351071Recruiting
Study of Signia circular stapler in left colon and rectal surgery
This study is testing a new circular stapler, called the Signia, used to reconnect the bowel during planned left-sided colon or rectal surgery. It aims to see how well the device works in everyday hospital settings.
New Haven, ConnecticutAges 18 years+ - NCT07356583Recruiting
Neonatal enterovirus infections in Italy
This study looks at enterovirus infections in newborn babies admitted to intensive care, focusing on one type called echovirus 11. It aims to better understand the virus and how it affects babies to improve care.
Pavia, LombardyAges 1 day–4 weeks - NCT07369726Recruiting
Mobilization and caffeine after cesarean
This trial tests whether getting out of bed and drinking coffee after a planned cesarean can help reduce pain and speed up recovery. It is for women who have moderate to severe pain after surgery.
KonyaAges 18–35 - NCT01416714Recruiting
Tissue sample collection during cancer surgery or biopsy
This study is collecting tissue samples from people with certain cancers while they have surgery or a biopsy. It may help researchers learn more about these cancers and improve future diagnosis and treatment.
Chicago, IllinoisAges Any age - NCT00267501Recruiting
Study collects data and samples to understand eosinophilic conditions
This study collects information and biological samples to better understand what causes certain allergic/eosinophilic conditions. It may help researchers learn mechanisms and improve future care.
Cincinnati, OhioAges Any age - NCT00899626Recruiting
Collecting stool and tissue markers from people with bowel conditions
This study collects samples (like tissue and other body fluids) from people who are getting a colonoscopy or similar camera test. It aims to find “biomarkers,” which are measurable signals that may help doctors better understand or detect bowel problems such as colorectal cancer, polyps, or inflammatory bowel disease.
Nashville, TennesseeAges 18 years+ - NCT00227253Recruiting
Study center for people with Chromosome 18
This trial is for people with Chromosome 18 (or the parent/guardian of a child with it) to take part in medical checkups and study evaluations. It may help researchers learn more about the condition and how to best evaluate patients safely.
San Antonio, TexasAges Any age - NCT01696734RecruitingPhase 3
Domperidone for difficult stomach and reflux problems
This trial studies whether domperidone can help people whose stomach or reflux symptoms did not improve with usual treatments. It focuses on symptoms like slow stomach emptying, hard-to-control acid reflux, or severe indigestion.
Houston, TexasAges 16 years+ - NCT01793168Recruiting
Rare disease registry and history study
This study keeps a registry (a structured list) of people with rare diseases and may also track how the condition changes over time. It can help researchers better understand rare illnesses and find gaps in care, which may improve future treatments.
Sioux Falls, South DakotaAges Any age - NCT02012699Recruiting
Cancer registry for people with or at risk of cancer
This trial collects health information and samples (a “cancer repository”) to help researchers study cancer and cancer risk. You may be able to join if you’ve had cancer before or if you’re at higher risk or have concerning findings.
Greenwood Village, ColoradoAges 19–110 - NCT02174549RecruitingPhase 1/Phase 2
Testing a drug with liver artery treatment for liver-spread neuroendocrine cancer
This early-stage study tests a cancer drug called tirapazamine, given along with a liver artery procedure (embolization) to treat liver-dominant metastatic neuroendocrine tumors. It aims to find a safe dose and see whether the combination can better control tumor growth in the liver.
Palo Alto, CaliforniaAges 20–99 - NCT02906943Recruiting
Testing cancer tissue to guide targeted treatment choices
This trial studies advanced solid tumors by using stored tumor samples to look for molecular clues. The goal is to help doctors better choose cancer treatments that may work for your specific tumor.
Hamilton, OntarioAges 18 years+ - NCT02185443RecruitingPhase 2
SBRT radiation for liver metastases that can’t be surgically removed
This trial studies stereotactic body radiation therapy (high-precision radiation given in a few sessions) for liver metastases when surgery isn’t possible. It may help shrink or control tumors in the liver and delay progression in people whose cancer has not spread outside the liver (or only to areas treated with a curative plan).
São Paulo, São PauloAges 18 years+ - NCT02584244RecruitingPhase 1/Phase 2
Testing an imaging scan to find gastrointestinal cancer
This study checks how well the LUM Imaging System can detect cancers of the esophagus, colon, or pancreas during the time you are preparing for surgery. It’s mainly meant to see if the scan works safely and clearly for doctors to find cancer areas.
Boston, MassachusettsAges 18 years+ - NCT02863250Recruiting
Blood transfusion registry for people needing frequent transfusions
This registry collects information from adults who receive frequent red blood cell transfusions. It may help clinicians understand transfusion needs and improve future care.
Melbourne, VictoriaAges 18 years+ - NCT03044223Recruiting

This study looks at patterns of immune cells in people who are critically ill with sepsis caused by Pseudomonas aeruginosa bacteria. It may help doctors better understand how the immune system responds and improve care for this serious infection.
UlmAges 18–90 - NCT05323409Recruiting
Better overall care for certain cancer patients
This study looks at how to improve day-to-day support and coordination between cancer doctors and primary care doctors for people with certain early cancers. It may help if you have other ongoing health problems (like diabetes or high blood pressure) or lifestyle factors that need ongoing management during cancer treatment.

Common questions
- Are there clinical trials for gastrointestinal?
- Yes. Clin2 currently lists 475 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.
