Comparing two ways to remove large colon polyps
This trial is for people with large (20-60 mm), non-cancerous colon growths on a wide base. It compares two endoscopic removal methods—ESD and EMR—to see which works best.
MoscowAges 18–100 - 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.
Sydney, New South WalesAges 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 - NCT07146165Recruiting
New tool for removing large growths in the rectum and lower colon
This trial tests a new platform to help doctors remove large polyps or early-stage cancers from the rectum and lower colon using a scope (endoscope). The goal is to see if this tool makes the removal process safer and more effective.
Freiburg im BreisgauAges 18 years+ - NCT07365436Enrolling by invitation
Better colon imaging with a new probe
This trial tests a new camera probe that works with a standard colonoscope to take better images of the colon. It may help doctors find polyps or other issues more clearly during a routine colonoscopy.
Boston, MassachusettsAges 45–75 - NCT06831305Enrolling by invitation
Nail coating study for high-risk healthcare workers
This trial tests whether a special nail coating reduces bacteria on the nails of healthcare workers. If you work in a high-risk ward, your nails can be checked and coated to see if it helps keep them cleaner.
LjubljanaAges 16–80 - NCT05742425RecruitingPhase 2
Immunotherapy with chemo and targeted drug for colon cancer in the belly
This Phase 2 trial tests serplulimab (immunotherapy) combined with FOLFIRI chemo plus bevacizumab for colon cancer that has spread to the lining of the abdomen (peritoneal metastases). It aims to shrink these tumors and improve outcomes when surgery can’t fully remove them.
Huzhou, ZhejiangAges 18–75 - NCT07525089Enrolling by invitation
Treatment to Clear Resistant Bacteria from Your Gut
This study tests whether a new treatment called BM111 can safely clear two types of antibiotic-resistant bacteria (CRE and VRE) that live in your intestines without causing infection. You'd provide stool samples over several weeks to see if the bacteria levels drop.
SeoulAges 19–65 - NCT07093463Recruiting
Colon-delivered Vitamin B2 for Gut Health
This trial tests whether a special form of vitamin B2 (riboflavin) delivered to the colon can improve gut health in people with mild to moderate bowel complaints. The study compares the effects of this supplement to a standard diet add-on (inulin) and looks at changes in gut bacteria and symptoms.
Berlin, State of BerlinAges 50–70 - NCT03125980RecruitingPhase 3
Chemo timing before vs after colon cancer surgery
This Phase 3 study compares two schedules of a colon cancer chemo combination: starting before surgery or starting after surgery. It aims to see which timing helps people live longer and lowers cancer coming back.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07723937Recruiting
GelPOINT-assisted removal of colon and rectal polyps
This study tests a new way to remove large or complex colon and rectal polyps using a special port system called GelPOINT Path. If you have polyps that are hard to remove with standard colonoscopy, this approach may help your doctor remove them safely.
Houston, TexasAges 18 years+ - NCT04120701RecruitingPhase 3
Using blood DNA tests to guide colon cancer treatment after surgery
This trial tests whether a blood test that looks at cancer DNA can help decide whether you need “adjuvant” (extra) chemotherapy after colon cancer surgery. It may help some patients avoid unnecessary chemotherapy while still keeping the cancer from coming back.
DijonAges 18–75 - NCT07412613RecruitingPhase 3
Immunotherapy Before and After Surgery for MSI-H Colon Cancer
This trial tests a new immunotherapy drug (AK104) given before and after surgery for a specific type of colon cancer that is MSI-H or dMMR. The goal is to see if the drug helps shrink the tumor and prevent the cancer from coming back.
GuangzhouAges 18–75 - NCT07041255Recruiting
Cold vs. Hot Loop Snare for Medium Colon Polyps
This trial compares two techniques (cold vs. hot loop snare) to remove medium-sized, non-cancerous colon polyps. It aims to find which method is safer and more effective for polyps that are 10–14 mm and flat or slightly raised.
MoscowAges 18–100 - NCT05174169RecruitingPhase 2/Phase 3
Adjuvant colon chemotherapy guided by tumor DNA results
This trial tests whether treatment for colon cancer after surgery can be guided by a blood test that looks for leftover cancer signals (ctDNA). It may help some people choose stronger or different chemo based on whether ctDNA is found after surgery.
Birmingham, AlabamaAges 18 years+ - NCT07740811Recruiting
Bacteria on double-J stents: risks and effects
This study looks at whether bacteria build up on double-J stents (small tubes that help drain urine) and what that means for your health. By checking the stent and urine samples before and after, doctors hope to learn how to reduce infections and improve care.
CairoAges 18 years+ - NCT06949111RecruitingPhase 2
Combining radiation and chemo to make colon cancer removable
This trial tests whether giving radiation therapy along with standard chemotherapy before surgery can help shrink advanced colon cancer that has grown through the bowel wall but hasn't spread to other organs. It is for a specific type of colon cancer called pMMR/MSS.
Shijiazhuang, HebeiAges 18 years+ - NCT05394714RecruitingPhase 1
Magicell-NK cell therapy after colon cancer surgery
This early-stage trial tests an individualized immune cell treatment (Magicell-NK) made from your own cells to help prevent colon cancer from coming back after surgery. It studies safety and how well the treatment works in people with early-stage colon cancer.
TaoyuanAges 20 years+ - NCT06927011Recruiting
Loose stools after colon cancer surgery: a study
This study looks at why some people have chronic loose stools after right-sided colon cancer surgery, possibly due to bile acid problems or bacterial overgrowth. It uses a new device to sample the small intestine.
Houston, TexasAges 20–85 - NCT06840977Recruiting
Low dose chemo for older adults with colorectal cancer
This trial tests a lower-dose chemotherapy regimen for adults aged 70 or older with metastatic colorectal cancer that has not been treated yet. It aims to see if a gentler approach can still be effective and easier to tolerate.
Genova, GEAges 70–99 - NCT03026140RecruitingPhase 2
Tested immune therapy before surgery for early colon cancer
This Phase 2 trial tests immune “checkpoint” medicines (and combinations) given before colon surgery to see if they can better control early colon cancer. It is aimed at people with non-metastatic colon cancer and certain tumor markers.
AmsterdamAges 18 years+ - NCT03779009Recruiting
Study mapping sentinel lymph nodes to guide colon cancer surgery
This trial looks at a minimally invasive surgery approach for people with colon adenocarcinoma that has not spread to lymph nodes or other organs. The team will use special mapping tests on the sentinel lymph node to better understand the cancer spread and help guide treatment decisions.
GhentAges 18 years+ - NCT03976960Recruiting
Database study for colon cancer surgery patients
This study collects clinical and lab information from people who have surgery for colon cancer (or certain precancer growths) and related spread to organs. It may help researchers better understand colon cancer and improve future care, but it is not a new medication trial.
