Leuven, Vlaams-BrabantAges 18 years+ - NCT04205968RecruitingPhase 2
Testing ramucirumab with chemo for advanced small bowel cancer
This trial studies whether adding ramucirumab to chemotherapy (either paclitaxel or FOLFIRI) works better for advanced small bowel adenocarcinoma that has already been treated with certain prior medicines. It may help shrink tumors or slow cancer growth in people whose cancer has progressed.
Anchorage, AlaskaAges 18 years+ - NCT06267378Recruiting
Frailty and its effects on older patients having major gut surgery
This study looks at how frailty affects recovery and outcomes for patients aged 70 and older who are having planned surgery to remove colorectal cancer. The goal is to better understand frailty's impact so care can be improved.
Doncaster, South YorkshireAges 18 years+ - NCT07608120Recruiting
Electrolyte drink with bowel cleansing solution for colonoscopy prep
This study tests whether combining an electrolyte beverage (a drink with salts and minerals) with polyethylene glycol—a standard bowel-cleaning solution—helps prepare your colon better for colonoscopy. The goal is to see if this combination makes the preparation easier to tolerate while still cleaning your bowel effectively.
Guangzhou, GuangdongAges 18–75 - NCT06831539RecruitingPhase 1
How bowel prep affects gut bacteria recovery
This study looks at how the bowel preparation medicine (PEG) used before a colonoscopy affects the bacteria living in your gut and how well they recover afterward. Healthy volunteers will take the bowel prep and provide stool samples to help researchers understand this process.
Montreal, QuebecAges 18–70 - 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 - NCT06914245Recruiting
Personalized help for bowel symptoms after rectal cancer treatment
This trial studies how to improve bowel symptoms in people treated for rectal cancer. It tests personalized care plans and looks at different factors that may contribute to bowel problems after surgery or a watch-and-wait approach.
Leuven, Vlaams-BrabantAges 18 years+ - NCT06887244Recruiting
Nurse phone support before colonoscopy
This trial studies whether a nurse phone call before an elective colonoscopy can improve the procedure experience, reduce anxiety, and lower financial stress.
NaplesAges 18–80 - NCT07215000RecruitingPhase 4
Better Colonoscopy Prep Options for Comfort
This trial compares different colonoscopy prep methods to see which one patients tolerate best. It aims to make the cleaning process before a colonoscopy more comfortable and acceptable.
Atlanta, GeorgiaAges 18 years+ - NCT03913962Recruiting
Exercise study for children with chronic or autoimmune conditions
This study looks at how physical activity affects muscle, metabolism (how your body uses energy), and body composition in children with certain chronic or autoimmune conditions. It may help doctors understand what types of exercise and monitoring are most beneficial and safe.
Clermont-FerrandAges 6–18 - NCT07347158Enrolling by invitation
Health education for ostomy patients
This study teaches people with an ostomy (a surgical opening for waste) about their health to improve their quality of life and reduce anxiety or depression. If you are an adult with a permanent or long-term ostomy and live in the Santiago or Barbanza area, you may be able to join.
Santiago de Compostela, A CoruñaAges 18 years+ - NCT07472686Recruiting
Capsule endoscopy for small bowel in Lynch syndrome
This study looks at how well a tiny camera in a pill (capsule endoscopy) can find early growths or cancer in the small intestine of people with Lynch syndrome. Lynch syndrome increases your risk for certain cancers, and this test might help catch them earlier.
ParisAges 18 years+ - NCT02997293Recruiting
Enhanced recovery after colorectal surgery care program
This study looks at whether a structured “enhanced recovery” plan around the time of colorectal surgery improves outcomes. Because it focuses on a specific group of surgeries done at a specific hospital during certain dates, it may be mainly for people whose surgeries match those records.
Little Rock, ArkansasAges 18 years+ - NCT04896684Recruiting
Study collecting gut health information from adults’ scans
This study is looking at people who need an intestinal scope (endoscopy) for gut symptoms or bowel conditions like IBS, IBD, or possible colorectal cancer. Your results may help doctors better understand these long-term conditions and improve follow-up care.
