- NCT07696793RecruitingPhase 4
Simethicone colonoscopy prep for cancer screening

Portland, OregonAges 45–85 - NCT05436054RecruitingPhase 4
Plenvu vs Picoprep bowel prep for colonoscopy
This study compares two bowel-cleansing products (Plenvu and Picoprep) to see which works better and is easier to tolerate before a colonoscopy. It may help patients by improving the chance of a clear exam and reducing unpleasant side effects.
Aalborg, North JutlandAges 18 years+ - NCT07623902Recruiting
Tongue test to improve colorectal cancer screening
This study is testing a new, non-invasive tongue test called Gixam. The goal is to see if the test can help detect colorectal cancer or pre-cancerous growths in people whose standard stool tests (FIT) came back negative, potentially improving screening accuracy.
Mobile, AlabamaAges 45–84 - NCT06709209Recruiting
AI tool for grading colitis during colonoscopy
This study uses a special AI system that analyzes images from a colonoscopy to help doctors better understand how active your ulcerative colitis is and predict how it might progress. If you are scheduled for a routine colonoscopy, this AI tool may help your doctor make more precise treatment decisions.
LeuvenAges 18–75 - NCT07587970Recruiting
Body Position and Oxygen Levels During Sedated Scope Procedures
This study tests whether your body position during recovery from sedated endoscopy (a camera procedure to examine your stomach and colon) affects your oxygen levels. The researchers want to find the best recovery position to keep your oxygen levels stable and safe.
Yinchuan, NingxiaAges 18 years+ - NCT06721195Recruiting
Study of Euphoria from Remimazolam During GI Scopes
This trial studies a sedative called remimazolam and how it makes people feel during routine upper and lower GI scope procedures. It may help doctors understand which patients are more likely to feel a sense of euphoria (a feeling of intense happiness) from the medicine.
Shanghai, Shanghai MunicipalityAges 18–65 - NCT06298461RecruitingPhase 4
Comparing bowel preps for Crohn's and colitis patients
