AntwerpAges 18–100 - NCT05676190Recruiting
Cell therapy using your own immune cells for colorectal cancer
This trial studies an immune cell treatment made from your own blood cells to treat colorectal cancer that has spread or progressed. You may be eligible if you have stage III–IV disease that can be measured on scans and if standard treatments have not worked or couldn’t be tolerated.
Chongqing, Chongqing MunicipalityAges 18–70 - NCT05689775Recruiting
Robot-assisted reconstruction using tummy muscle flap after surgery
This trial studies a specific way to rebuild the pelvic floor (and sometimes the vagina) after major rectal or anal cancer surgery. It uses robotic surgery and a flap taken from your tummy muscle to help close and reconstruct the area.
OsloAges 18 years+ - NCT04095195Recruiting
Pancreatic cancer risk registry for high-risk families
This study builds a registry of people with a higher-than-average risk of pancreatic cancer, based on family history or inherited gene conditions. If you join the extra imaging follow-up, it helps your care team monitor risk earlier.
Rozzano, MilanAges 18–80 - NCT04486131Recruiting
Test for treatment of recurrent rectal cancer in side lymph nodes
This trial focuses on rectal cancer that has come back in the side lymph nodes near the pelvis. It tests how to treat that “lateral nodal recurrence” to improve outcomes by targeting these specific lymph nodes.
Amsterdam, North HollandAges 18 years+ - NCT05696002Recruiting
Track outcomes after advanced pelvic cancer surgery
This study follows people who have advanced pelvic cancer surgery that removes more than one pelvic organ. It’s an observational study, meaning it mainly collects data to help improve how future surgeries and care are planned.
GlasgowAges Any age - NCT02669992Recruiting
Compare closure methods for a loop ileostomy after rectal cancer
This trial studies which technique works best to close a loop ileostomy after rectal cancer surgery. It compares different closure methods to see which is safer and more effective for patients.
GothenburgAges Any age - NCT04014530RecruitingPhase 1/Phase 2
Testing pembrolizumab plus ataluren for metastatic dMMR or pMMR cancer
This early-phase trial tests pembrolizumab combined with ataluren for people with metastatic colorectal cancer that has either dMMR or pMMR, and for metastatic dMMR endometrial cancer. The goal is to see whether this combination can shrink tumors or improve outcomes for cancers with specific mismatch repair (MMR) features.
Amsterdam, North HollandAges 18 years+ - NCT05501353Recruiting
Study tumor biomarkers in recurrent metastatic colon cancer
This study looks for blood/tumor signals (“biomarkers”) that may help predict outcomes in people whose colorectal cancer returns and spreads after surgery. It mainly helps researchers understand who may do better or worse, which can guide future care.
Hangzhou, ZhejiangAges 18–99 - NCT02421705Recruiting
Brain-gut sensitivity study in IBS and inflammatory bowel disease
This study checks how sensitive your gut is to normal stimuli in people with IBS, ulcerative colitis, Crohn’s disease, and in healthy volunteers. Results may help researchers understand why some people feel more abdominal discomfort and how that connects to inflammatory bowel conditions.
Leuven, Vlaams-BrabantAges 18–65 - NCT01140789Recruiting
Study comparing people with and without bowel inflammation
This study looks at people with inflammatory bowel disease (Crohn’s disease or ulcerative colitis) and compares them with people without it. Researchers want to understand differences that may help explain or better detect the disease.
Hong KongAges 18 years+ - NCT03855657Recruiting
Biobank study of gut microbes, genes, and blood chemistry
This study collects samples to learn how gut microbes, genetics, and body chemistry may relate to Crohn’s disease or ulcerative colitis. Your information and samples may help researchers understand disease patterns, but it does not test a new drug.
Hong KongAges 18 years+ - NCT05722275Recruiting
Predicting peritoneal spread in advanced stomach cancer
This trial uses CT scan images and a look inside the abdomen (laparoscopy) to predict whether advanced stomach cancer has spread to the lining of the abdomen (the peritoneum). It may help your care team better identify who already has peritoneal spread and who might not.
BeijingAges 18 years+ - NCT05469607Recruiting
Tested a device to treat Crohn’s after bowel surgery
This study looks at using a new neurotechnology-based approach (a technology that talks to the nervous system) for people with Crohn’s disease after they’ve had bowel surgery. It’s meant for patients whose new surgical connection (an anastomosis) looks normal on scope and is reachable by colonoscopy.
Melbourne, VictoriaAges 18–80 - NCT05718492Recruiting
Tested HAIC for liver cancer after prior immunotherapy
This trial studies HAIC, a type of targeted treatment delivered into the liver, for advanced hepatocellular carcinoma (liver cancer) that has already been treated with immune and anti-blood-vessel therapies. It aims to see whether HAIC can help control the cancer safely after those earlier treatments.
Guangzhou, GuangdongAges 18–75 - NCT05724992Recruiting
Study genetic testing in families at pancreatic cancer risk
This program invites people whose families are followed in a pancreatic cancer registry to do a saliva swab genetic test. It helps researchers learn how to identify genetic risk in families and may guide future care.
VeronaAges 18–80 - NCT05723718Recruiting
Testing body-water measurements in people with stomach cancer
This trial uses a painless machine to measure your body composition (mainly fluid and muscle) using bioelectrical impedance. It’s looking at people with stage II–III stomach cancer who are receiving standard “multi-treatment” care, to see whether these measurements are useful during treatment.
LublinAges 18–100 - NCT03466424Recruiting
Short radiation then chemotherapy for locally advanced rectal cancer
This trial tests a short course of radiation given before chemotherapy for people with locally advanced rectal cancer (cancer that has grown into nearby tissue and/or nearby lymph nodes but can still be removed). It may help shrink the tumor and make treatment more effective while assessing how well this approach works.
Fuzhou, FujianAges 18–70 - NCT04743102Recruiting
Multi-point full-thickness biopsy to confirm complete rectal cancer response
This trial checks whether taking small samples from the full thickness of rectal tissue can accurately confirm that rectal cancer has fully responded to chemotherapy and/or radiation. It may help doctors decide the best next step if no tumor is seen after treatment.
Beijing, Beijing MunicipalityAges 18–80 - NCT05018663Recruiting
AI test of fluid samples from pancreatic cysts
This trial uses artificial intelligence (AI) to help interpret fluid/scraping samples taken with a needle from pancreatic cysts. You might be eligible if an ultrasound/endoscopy exam found a pancreatic cyst called a PSL and it’s safe for you to have that needle procedure (FNA/FNB).
Houston, TexasAges 18–100 - NCT05202314Recruiting
Camrelizumab plus chemo after stent for left bowel cancer
This study tests whether adding camrelizumab (an immune therapy) to chemotherapy—after a stent is placed to open a blocked left-sided colon—improves outcomes. It’s meant for people whose cancer can still be removed with surgery after the blockage is treated.
Beijing, Beijing MunicipalityAges 18–80 - NCT05725200RecruitingPhase 2
Personalized treatment plan for metastatic colon or rectal cancer
This Phase 2 trial tests an individualized treatment chosen from your tumor’s lab testing (genetic and RNA profile plus a drug-sensitivity test from your tumor cells). It may help by matching you to targeted anti-cancer drugs that are most likely to work for your specific cancer.
OsloAges 18 years+ - NCT05738980Recruiting
Reduce liver cancer return after surgery using anti–TIM-3
This trial studies whether blocking TIM-3 (an immune “brake”) can help stop hepatocellular carcinoma (liver cancer) from coming back after a curative surgery. It may help by improving your immune system’s ability to find and control remaining cancer cells.
Beijing, Beijing MunicipalityAges 18–75 - NCT05740696Recruiting
Registry study for managing liver failure in China
This is a study that collects real-world information about people with liver failure or “pre-liver failure.” It aims to help doctors choose the best management approach for patients like you and improve care over time.
