HsinchuAges 20 years+ - NCT05225428Recruiting
Video education program based on personal genetic result disclosure
This study tests a video-based education approach that shares information differently depending on someone’s genetic test results. It may help people better understand cancer-related genetic information and what it could mean for them.
Boston, MassachusettsAges 18 years+ - NCT05228431RecruitingPhase 2
Tested treatment plan for locally advanced rectal cancer
This Phase 2 study looks at a modified “sandwich” treatment sequence for people with locally advanced rectal cancer—aiming to control the cancer before and after surgery. It may help you if you’re eligible and can follow the study’s treatment and safety requirements.
Guangzhou, GuangdongAges 18–75 - NCT05229003RecruitingPhase 2
Irinotecan, anlotinib, and pembrolizumab-like drug for advanced colon cancer
This Phase 2 study tests adding anlotinib and penpulimab to irinotecan for colorectal cancer that has come back or spread after earlier chemotherapy. It may help shrink tumors and control the disease when standard first-line treatment no longer works.
Shanghai, Shanghai MunicipalityAges 18–85 - NCT05229432Recruiting
Oatmeal meal test to study stomach movement in eosinophilic gastritis
This study looks at how your stomach moves (gastric motility) in people with eosinophilic gastritis, using a special oatmeal meal. The goal is to better understand stomach function and how it may relate to symptoms.
Chicago, IllinoisAges 18–59 - NCT05231876Recruiting
French Wilson disease registry
This study keeps a registry (a confidential list) of people with Wilson disease. It helps researchers learn more about the disease and improve future care, without requiring specific treatment changes.
Paris, Île-de-France RegionAges birth–99 years - NCT05234177Recruiting
Blood test to track colorectal cancer after surgery
This study looks at a blood “DNA” test to see if it can help monitor colorectal cancer after surgery. It may benefit you by improving how doctors track cancer during routine follow-up visits.
Fort Smith, ArkansasAges 18 years+ - NCT05236972RecruitingPhase 3
PD-1 antibody after colon cancer surgery for dMMR stage III
This phase 3 trial studies a PD-1 antibody medicine given after surgery to help prevent stage III colon cancer from coming back. It is specifically for people whose tumor is mismatch repair–defective (dMMR) or MSI-H, which may make the cancer more responsive to immune-based treatment.
GuangzhouAges 18–75 - NCT05239338Recruiting
Preserving fertility after colorectal cancer
This study looks at how to help people protect their ability to have children after colorectal cancer. It mainly includes younger adults who were diagnosed for the first time and can complete study questionnaires.
Nashville, TennesseeAges 18–49 - NCT05239546RecruitingPhase 2
Dostarlimab before colon surgery for mismatch-repair–deficient cancer
This study tests dostarlimab given before surgery for stage II or III colon cancer that has a specific DNA repair defect. It aims to shrink or control the cancer so that some people may be able to skip surgery if the results are good.
Iowa City, IowaAges 18 years+ - NCT05239858Recruiting
International registry for people with Wilson’s disease
This trial is a patient registry that collects health information from people with Wilson’s disease, including those without symptoms yet and those taking any type of treatment. It helps researchers understand the disease and how it progresses, which can support future studies and care improvements.
LeuvenAges 12 years+ - NCT05240950RecruitingPhase 1
CAR-T cell therapy for colorectal cancer in the liver
This Phase 1 study tests an anti-CEA CAR-T cell treatment for people whose colorectal cancer spread to the liver but has been surgically removed with no visible remaining tumor. It aims to see if the treatment can better prevent the cancer from coming back, especially when early warning tests suggest leftover cancer cells.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05241249RecruitingPhase 2
Bethanechol plus chemotherapy for pancreatic cancer
This trial tests whether adding bethanechol to standard chemotherapy (gemcitabine and nab-paclitaxel) can work better for people with pancreatic ductal adenocarcinoma. You may be considered if your cancer is not spread and you can safely take the medicines and follow study visits.
New York, New YorkAges 18 years+ - NCT05244629Recruiting
Compare two stents for chronic artery-related gut pain
This trial tests whether an uncovered stent or a covered stent works better for treating chronic mesenteric ischemia (reduced blood flow to the intestines from artery narrowing). It’s meant for adults with symptoms and scans showing significant narrowing in a specific gut artery.

Study of genes, tumor environment, and immune factors in pancreatic cancer
This study looks at tissue samples from people with pancreatic ductal adenocarcinoma to understand how genes, the tumor “neighborhood,” and the immune response may affect the cancer. Your participation may help researchers learn what drives the disease and how treatment might work better for you.
Rome, LazioAges 18–80 - NCT05250648RecruitingPhase 4
HIPEC with mitomycin C after surgery for colon cancer in the belly
This study looks at adding a heated medicine treatment (HIPEC with mitomycin C) during surgery to treat colon cancer that has spread to the lining of the abdomen (peritoneum). It aims to improve outcomes after surgeons remove visible tumor completely.
