Recruiting studies
- 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+ - NCT04815525Recruiting
Long-term bowel cancer risk after colonoscopy in Hong Kong
This study follows people in Hong Kong over time to learn how the future risk of advanced colon growth changes after they have a colonoscopy. It may help doctors better predict who needs closer follow-up in the years after a colonoscopy.
Shatin, New TerritoriesAges Any age - NCT06333392Recruiting
Underwater colonoscopy for better cancer screening
This trial tests if a new type of colonoscopy called total underwater colonoscopy (TUC) is better at finding polyps and cancer during routine screening. If you had a positive FIT stool test and are scheduled for a follow-up colonoscopy, you may be able to join.
DrammenAges 55–60 - 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 - NCT07740122Recruiting
Stool photo analysis for colorectal cancer screening
This study tests whether photos of your stool can help predict your risk of colorectal cancer or precancerous growths. It uses a smartphone app to analyze stool images alongside your routine stool test (FIT) results.
Santiago, Santiago MetropolitanAges 18 years+ - NCT06946615RecruitingPhase 1
Claudin18.2 cell therapy for advanced colorectal cancer
This study tests a new treatment using your own immune cells (called CAR-T and CAR-DC) that are engineered to attack cancer cells with a specific protein (Claudin18.2). It is for people with advanced colorectal cancer who have exhausted standard treatments.
Hangzhou, ZhejiangAges 18–70 - NCT05410977Recruiting
Testing blood and stool for colon cancer in Lynch syndrome
This study collects blood and stool samples to see how well they can detect colorectal cancer or advanced growths in people with Lynch syndrome (an inherited colon cancer risk) or suspected Lynch syndrome. It may help find cancer or precancer earlier, which can improve next-step decisions.
Scottsdale, ArizonaAges 18 years+ - NCT07786818Recruiting
Colorectal cancer screening marker study
This study looks for markers in stool and saliva that might indicate the presence of precancerous growths in the colon. If you are scheduled for a colonoscopy, you may be able to participate by providing samples beforehand.
Bothell, WashingtonAges 18 years+ - NCT05402696Recruiting
Study of advanced surgery care for colorectal tumors
This study follows adults who are referred for treatment of a specific type of colorectal tumor that involves the left side of the colon. It aims to improve care and outcomes for people needing advanced surgery.
Saint Cloud, MinnesotaAges 18 years+ - NCT07623902Recruiting
Testing a Tongue Scan to Detect Colorectal Polyps
This study tests whether a new tongue-scanning tool called Gixam can help find advanced colorectal polyps in people with negative stool tests. If it works, it might offer a simpler screening option alongside colonoscopy.
Orlando, FloridaAges 45–84 - NCT06271941Recruiting
Reducing polyp return after large colon polyp removal
This trial is testing a standard way to remove large polyps from the colon and checking if it helps prevent them from coming back. It's for people who have a large non-cancerous polyp that needs to be taken out during a colonoscopy.
Montreal, QuebecAges 18 years+ - NCT07158164RecruitingPhase 4
Genetic testing for chemotherapy dose adjustment
This trial checks if adjusting the dose of chemotherapy drugs 5-FU or capecitabine based on your DPYD genetic results can improve safety and effectiveness. It’s for people with cancer who are about to start these drugs for the first time.
Belleville, New JerseyAges 18 years+ - NCT06907095Recruiting
Early cancer detection study for high-risk individuals
This study tests if a simple blood or fluid test can find cancer early in people with a higher-than-average risk. If you have certain genetic mutations, a strong family history of cancer, or other high-risk conditions, you may be able to join.

Common questions
- Are there clinical trials for colorectal neoplasia?
- Yes. Clin2 currently lists 14 recruiting colorectal neoplasia 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 colorectal neoplasia 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 colorectal neoplasia 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.
