Recruiting studies
- NCT05935124Recruiting
White light or narrow-band imaging for colon polyp detection
This trial compares two camera light styles during screening colonoscopy to see which one better finds polyps on the right side of the colon. If you’re having a routine screening and have no concerning symptoms, the results may help improve how doctors spot polyps early.

Atlanta, GeorgiaAges 18 years+ - NCT06406062Recruiting
AI-assisted colonoscopy study
This trial tests an artificial intelligence (AI) system during colonoscopy to help doctors see polyps or other issues more clearly. It may help improve detection of problems in the colon.
Wuhan, HubeiAges 50 years+ - 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+ - NCT07165470Recruiting
Pre-packaged low-residue diet for IBD colonoscopy prep
This study tests whether a ready-to-eat low-residue diet (a diet that leaves very little waste in your colon) helps people with IBD prepare for a colonoscopy. It may make the prep easier and more effective than standard bowel-cleansing drinks.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07140679RecruitingPhase 2
Immunotherapy after surgery for certain colon cancers
This trial tests whether giving an immunotherapy drug called toripalimab after surgery can lower the chance of colon cancer coming back. It is for people whose tumors have a specific genetic feature called mismatch repair deficiency (dMMR) and who have had their cancer completely removed.
Atlanta, GeorgiaAges 18 years+ - NCT07127471Recruiting
Comparing two colonoscopy methods for finding pre-cancerous polyps
This study tests two different colonoscopy techniques to see which one finds more pre-cancerous polyps called serrated lesions. It may help your doctor choose the best way to screen for colon cancer during your procedure.
Montreal, QuebecAges 40–80 - NCT02594813Recruiting
Bleeding risk check for endoscopy in people on blood thinners
This trial looks at how often bleeding happens after an upper scope (EGD) or colonoscopy in people who keep taking blood-thinning medicines during the procedure. The results may help doctors choose safer prep plans to lower bleeding risk.
KomaganeAges 20–90 - NCT07089615Recruiting
Capsule vs colonoscopy for polyp detection
This trial tests a new capsule that you swallow to take pictures of your colon. It may help find polyps (growths that can turn into cancer) as well as a standard colonoscopy does.
Chula Vista, CaliforniaAges 45–75 - NCT07090291Recruiting
China colorectal cancer screening trial for adults 45–74
This trial is testing a new way to screen for colorectal cancer in adults aged 45 to 74. If you join, you will help researchers find better methods for early detection.
GuandongAges 45–74 - NCT07052799RecruitingPhase 3
Should you pause aspirin before a colonoscopy?
This trial compares stopping aspirin versus continuing it before a colonoscopy in people who take aspirin to prevent heart problems. The goal is to find out which approach is safer and works best.

Study gut immune tissue in HIV cure efforts
