Testing M3 and FIT to predict polyp return in colon exams
This study checks how well two lab tests (M3 and FIT) can predict whether advanced colon polyps (adenomas) will come back. If you’ve had adenomas found on a prior colonoscopy, these results may help plan future surveillance.
Shatin, New TerritoriesAges 18 years+ - NCT07167342RecruitingPhase 4
Can a probiotic prevent polyp regrowth after colonoscopy?
This trial tests whether taking a probiotic called Clostridium Butyricum after colon polyp removal can lower the chance of polyps coming back. It is looking for people who had adenomas removed and are not already taking certain supplements or antibiotics.
Qingdao, ShandongAges 18–75 - NCT05592886Recruiting
Oral probiotic-and-prebiotic drink to prevent colon polyps returning
This study tests whether an oral synbiotic (a probiotic plus a prebiotic) can reduce the chance that advanced colon growths come back after they were removed. It also looks at changes in stool-related bacterial “gene markers” that may signal lower risk over time.
Hohhot, Inner MongoliaAges 18–90 - NCT05988645Recruiting
Study of a new device to improve colonoscopy
This trial tests a new tool called MiWEndo that helps doctors better see and remove polyps during a colonoscopy. It is for people who already have a polyp in the rectum that needs to be taken out.
BarcelonaAges 18 years+ - NCT06342440Recruiting
Early detection of colon cancer and advanced polyps
This study aims to find colorectal cancer and advanced polyps (adenomas) earlier by looking at blood samples. Researchers hope a simple blood test might one day help detect colon cancer before it spreads.
Monrovia, CaliforniaAges 18 years+ - NCT05612347Recruiting
Compare stool test vs colonoscopy for older adults with polyps
This study compares two ways to check for colon polyps in older adults: using a stool test versus having a colonoscopy. It may help find a simpler option if you only had a small number of lower-risk polyps before.
Birmingham, AlabamaAges 65–82 - NCT07073430Recruiting
AI tool to help diagnose precancerous colon polyps
This trial tests an artificial intelligence system that helps doctors find and diagnose tubular adenomas (a type of precancerous polyp) during colonoscopy. It may improve early detection of colorectal cancer.
Wuhan, HubeiAges 18 years+ - NCT07621757Enrolling by invitation
Genetic Risk Testing for Colorectal Cancer Screening
This study looks at how genetic risk information can help decide who needs colorectal cancer screening and when. Researchers want to see if testing for genetic risk factors improves screening decisions for people who haven't had a colonoscopy before.
Evanston, IllinoisAges 45–75 - NCT06930157RecruitingPhase 4
Shenling Baishu Granule to prevent low-risk colon polyp return
This study tests if a Chinese herbal medicine (Shenling Baishu Granule) can help prevent low-risk colon polyps from coming back after they've been removed. It is for people who have had a good colonoscopy and had their polyps taken out within the last 3 months.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT04185779Recruiting
Colorectal cancer screening colonoscopy study
This study looks at patterns of colorectal (colon and rectum) findings in people who are having a colonoscopy as part of routine care. It may help improve how doctors detect and understand colorectal cancer and related growths over time.
South Shields, Tyne and WearAges 18 years+ - NCT07450612Recruiting
Blood test and AI for early colorectal cancer detection
This study uses a simple blood test (liquid biopsy) and computer analysis to find early signs of colorectal cancer, precancerous growths, and Lynch syndrome. It aims to improve early detection and monitor for any remaining cancer after treatment.
Milan, LombardyAges 18 years+ - NCT06612281RecruitingPhase 2
Testing a new screening tool for colorectal cancer in people with negative FIT results
This trial tests a new device called Gixam to see if it can help find colorectal cancer in people who recently had a normal FIT test (a stool test for blood). You may be able to join if you are between 45 and 85 years old and are already scheduled for a routine screening colonoscopy.
Portland, OregonAges 45–85 - NCT06205862RecruitingPhase 2
Fecal transplant for preventing colon polyp return
This study tests whether taking capsules of healthy bacteria (fecal microbiota transplant) can help prevent colon polyps from coming back after they have been removed. It might be an option for people who have had an adenoma polyp removed and want to reduce the chance of recurrence.
Guangzhou, GuangdongAges 18–75 - NCT06452745Recruiting
Early colon cancer detection using a blood test
This study uses a simple blood test to find early signs of colorectal cancer in people who already had a positive stool test. If it works, it could help avoid unnecessary colonoscopies in the future.
Reus, TarragonaAges 50–70 - NCT05381792Recruiting
Test of gut bacteria changes after colon tumor removal
This study looks at how the gut’s bacteria and bacterial gene signals change after doctors remove certain advanced growths in the colon using endoscopy. If you need an endoscopic procedure for an advanced adenoma or early colon cancer, your stool/bacteria samples may help researchers understand what changes after treatment.
Shatin, New TerritoriesAges 18–90 - NCT05405673Recruiting
Test stool or tissue genes to find advanced colon growth
This study checks how well a set of bacterial gene markers (a DNA-like test) can help identify advanced “precancer-like” or higher-risk growths in the colon. It may help doctors better target who needs closer follow-up during colonoscopy.
Hong KongAges 18 years+ - NCT06629051Recruiting
Long-term follow-up after berberine treatment trial
This study checks on people who took berberine in an earlier trial to see how they are doing 6 years later. It helps researchers understand the long-term effects of the treatment.
ShanghaiAges Any age - NCT06924489Recruiting
3D imaging for better adenoma detection during colonoscopy
This trial tests a 3D imaging device during colonoscopy to see if it helps find more advanced adenomas (precancerous polyps) than standard colonoscopy. If you are scheduled for a diagnostic colonoscopy and haven't had colorectal cancer or polyps removed before, this study might be for you.
Xi'an, ShaanxiAges 18–75 - NCT06307938Recruiting
Liquid biopsy test for colorectal cancer before colonoscopy
This trial tests a simple blood test (liquid biopsy) to find cancer signals in the DNA of people being called for a colonoscopy. If you are scheduled for a colonoscopy, your blood sample could help doctors detect colorectal cancer earlier and plan better treatment.
LevangerAges 18 years+ - NCT06957626Recruiting
Predicting polyp return after removal
This study aims to develop a tool using gut bacteria and metabolites to predict if high-risk colon polyps will come back after removal. If you are between 40 and 75 and have had certain types of colon polyps removed, you may be able to help us build better prediction methods.
BeijingAges 40–75 - NCT06715384Recruiting
Testing a new camera tool to measure colon polyps
This trial tests a computer-assisted measurement system during a colonoscopy to see if it can more accurately measure polyps. You might consider this if you are scheduled for a routine colonoscopy for screening or monitoring.
