Recruiting studies
- NCT07470658Enrolling by invitation
Surveillance after positive FIT and normal colonoscopy
This trial studies the best way to follow up with people who had a positive FIT stool test (high blood level) but a normal colonoscopy. It aims to find the right schedule for future screening to catch any problems early.
TaipeiAges 45–74 - NCT07353853Recruiting

This trial tests if a special pre-packaged low-residue diet can improve bowel preparation for colonoscopy in people with inflammatory bowel disease (IBD). It aims to make the prep easier and more effective.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07328880Recruiting
Two bowel prep methods before colonoscopy study
This trial compares two ways to clean the bowel before a colonoscopy: a 4-liter split-dose of a laxative plus two other medications versus a 2-liter split-dose with a gas-relief medication. The goal is to see which works better and is easier to tolerate.
Tanta, GharbyeaAges 18–70 - NCT06874036Recruiting
Bowel prep and colonoscopy safety in heart, kidney, or liver disease
This study tests how well people with chronic heart, kidney, or liver disease tolerate bowel preparation and colonoscopy. It aims to ensure the procedure is safe and effective for you.
Hyderabad, TelanganaAges 18–75 - NCT07229066Recruiting
Video education for better colonoscopy prep
This study tests whether watching a short educational video can help you prepare better for a colonoscopy. If you haven’t had a colonoscopy before and you or a family member has a smartphone, this study might be for you.
EskişehirAges 18–80 - NCT07127354RecruitingPhase 4
GLP-1 medications and colonoscopy prep quality
This study tests whether a special bowel preparation plan works better for people taking GLP-1 or GIP medications (like Ozempic, Mounjaro) before a colonoscopy. It aims to improve the quality of the bowel cleaning so doctors can see the colon more clearly.
Cleveland, FloridaAges 18 years+ - NCT07076966Recruiting
3D vs. 2D colonoscopy for better polyp detection
This trial compares two ways of looking at the inside of the colon during a follow-up colonoscopy: standard 2D imaging versus a newer 3D view. The goal is to see if the 3D method helps doctors find more polyps (small growths that can turn into cancer) so they can remove them earlier.
HsinchuAges 40 years+ - NCT07067424Recruiting
Aromatherapy for anxiety during colonoscopy
This study tests if smelling lavender or bergamot oil can reduce anxiety for people having a colonoscopy. If you are nervous about the procedure, this simple treatment might help you feel calmer.
FamagustaAges 18 years+ - NCT07066046Recruiting
AI-assisted colonoscopy for finding colorectal lesions
This trial tests whether artificial intelligence can help doctors better detect and classify growths in the colon during a colonoscopy. You may benefit from potentially more accurate results.
São Paulo, São PauloAges 18 years+ - NCT07023471Enrolling by invitation
AI-assisted colonoscopy for cancer screening, tandem study
This study tests whether a smart computer program (artificial intelligence) can help doctors find more polyps during a standard colonoscopy for colorectal cancer screening. It may improve detection of early signs of cancer.
Bangkok, BangkokAges 40–85 - NCT06983639Recruiting
Fecal test vs. colonoscopy follow-up after polyp removal
This trial compares using a simple stool test (FIT) versus a repeat colonoscopy to check for new polyps in people who have already had an advanced adenoma removed. It aims to see if the stool test is a safe and effective alternative for routine follow-up.
Arendal, AgderAges 40–75 - NCT06916052Recruiting
Digital platform for preparing for outpatient colonoscopy
This trial tests a digital platform to help patients prepare for and follow up after a colonoscopy. It may make the process easier and more accessible for people who regularly use a smartphone.
Barcelona, BarcelonaAges 18–80 - NCT06805890Recruiting
Tissue repair study in IBD using organoid technology
This study collects tissue samples from people with Crohn's disease or ulcerative colitis during routine colonoscopy or surgery to grow mini-organs (organoids) in the lab. The goal is to learn how the gut heals itself, which could lead to better treatments.
MarseilleAges 18 years+ - NCT06688955Recruiting
Using clean water during colonoscopy to reduce infection risk
This trial tests whether using water that is tested for bacteria during a colonoscopy can reduce the risk of infection. It may help make the procedure safer for you.
PessacAges 18 years+ - NCT06496958Recruiting
Better colonoscopy with water, CO2, and a belly compression belt
This study tests a new approach to make colonoscopy easier and more comfortable by using water, carbon dioxide gas, and a soft belly compression device instead of the standard air. The goal is to help patients need less manual pushing from the doctor during the procedure.
Kaohsiung CityAges 45–80 - NCT06314022Recruiting
Mobile app for better colonoscopy in cancer screening
This study tests a mobile app designed to help improve the quality of colonoscopies for people in a colorectal cancer screening program. If you have had a positive FIT test and are between 50 and 69, you may be able to join.
Valladolid, ValladolidAges 50–74 - NCT03891251Recruiting
Recorded videos during your colonoscopy
This study collects recorded video from routine colonoscopies. It may help researchers by providing real-world footage while you receive standard care.
JerusalemAges 18 years+ - NCT05051046Recruiting
Screening colonoscopy with hypnosis for colorectal cancer
This trial studies whether using hypnosis during a screening colonoscopy can help people better tolerate the procedure and complete it comfortably. It’s for adults who are scheduled for a routine screening colonoscopy and meet specific safety and communication requirements.
AngersAges 18–100 - 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 - NCT05929365Recruiting
Test genetic marker tracking to find returning colon polyps
This study looks at stool or tissue DNA changes (called mutation analysis) plus colonoscopy findings to detect whether colon polyps come back. It may help catch recurrent colorectal lesions earlier during surveillance after a large polyp was removed.
PragueAges 18–75 - NCT07790718Recruiting
Exercise program to prevent colorectal cancer after prostate radiation
This study tests whether an exercise program can help prevent colorectal cancer in men who have had pelvic radiation for prostate cancer. It involves using an iPhone app to track activity and attending exercise sessions.

Stopping GLP-1 drugs before colonoscopy: a trial in Taiwan
This study looks at whether stopping GLP-1 receptor agonists (a type of diabetes or weight-loss medication) before a colonoscopy can help improve the procedure. It compares how well the bowel is cleaned in people who stop these drugs for a certain time versus those who continue them.
New Taipei, TaiwanAges 18–90 - 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.

- How do I know if I qualify for a colonoscopy 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 colonoscopy 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.
