Recruiting studies
- NCT07154316RecruitingPhase 2
Short radiation plus drugs for MSS rectal cancer
This trial tests a shorter course of radiation therapy followed by a combination of chemotherapy, immunotherapy, and a pain-relief medication, compared to the standard approach. It is for people with a certain type of rectal cancer that has not spread.
Fuzhou, FujianAges 18–75 - NCT07116668Enrolling by invitation
Colovac device study for colon surgery patients
This trial tests a device called Colovac that protects the connection made during colon surgery for cancer. It may help patients who need a temporary colostomy bag heal better.
Los Angeles, CaliforniaAges 22 years+ - NCT06965335Recruiting
Early-onset colorectal cancer study
This study looks at colorectal cancer that starts early in life (ages 18–40). It compares it to the same cancer in people over 60 to find differences. You can join if you have had colorectal cancer and can provide a sample of your tumor.
Milan, MilanoAges 18–40 - NCT06968221RecruitingPhase 3
Bovine reinforcement for stomach, colorectal, and lung surgery
This trial tests whether a bovine reinforcement material helps make staple lines in stomach, colorectal, and lung surgeries stronger and safer. It may reduce the risk of leaks or bleeding at the staple line.
ShanghaiAges 18–75 - NCT07058012RecruitingPhase 2
Testing immunotherapy for ctDNA-positive colorectal cancer after treatment
This trial is for people with colorectal cancer whose ctDNA blood test is still positive after surgery and chemotherapy. It tests two immunotherapy drugs (cemiplimab alone or with fianlimab) to see if they can eliminate the remaining cancer cells and prevent the cancer from coming back.
Gainesville, FloridaAges 18 years+ - NCT07046585Recruiting
Blood test for colon cancer screening
This trial tests a new blood test to screen for colorectal cancer in people at average risk. You would give a blood sample before your scheduled colonoscopy, and the results will be compared to the colonoscopy findings.
Austin, TexasAges 40 years+ - NCT07003022RecruitingPhase 2
Two-drug combo for advanced colorectal cancer
This trial tests a combination of two drugs (cadonilimab and an anti-angiogenic agent) for advanced colorectal cancer that has a specific genetic feature (dMMR or MSI-H). It aims to find a new treatment option that might work better than current therapies.
Shanghai, ChinaAges 18–80 - NCT06957015Recruiting
New system to measure polyp size during colonoscopy
This trial tests a new computer system that helps doctors estimate the size of polyps during a colonoscopy. It may help doctors make better decisions about your treatment.
ShatinAges 18 years+ - NCT06630624RecruitingPhase 1/Phase 2
IP-001 with ablation for colorectal liver metastases
This trial tests whether adding the drug IP-001 to tumor ablation (microwave or irreversible electroporation) helps control colorectal cancer that has spread to the liver. The goal is to find the best dose and see how the immune system responds.
Amsterdam, North HollandAges 18 years+ - NCT05314400Recruiting
MRI with contrast for metastatic colon cancer liver lesions
This trial studies an MRI technique using a contrast dye (gadopetate/gadolinium) to better look at liver lesions that may be colon cancer spread. It may help doctors more accurately assess which liver tumors are present and guide next steps.
London, OntarioAges 18 years+ - NCT06807073Recruiting
Closing the wound after large colon polyp removal
This study compares closing the wound after removing a large colon polyp to leaving it open. The goal is to see if closing the area reduces bleeding or other problems.
Montreal, QuebecAges 18 years+ - NCT06783491RecruitingPhase 3
Chemotherapy with or without heated chemo for advanced colon cancer
This trial tests if adding heated chemotherapy directly into the abdomen during surgery improves outcomes for people with advanced colon cancer that hasn't spread to other organs. It compares standard chemotherapy before surgery alone versus chemotherapy before surgery plus heated chemo during surgery.
Córdoba, CórdobaAges 18–75 - NCT06696534Recruiting
Patient views on colorectal cancer screening methods
This study asks people aged 50–69 about their experience and preferences with different screening methods for colorectal cancer. It aims to improve screening programs by understanding what patients prefer.
LisbonAges 50–69 - NCT05706779RecruitingPhase 2
Encorafenib plus cetuximab before surgery for BRAF-mutated colon cancer
This trial tests whether giving encorafenib and cetuximab before surgery can shrink or control BRAF-mutated colon or upper rectal cancer and make surgery more effective. It also checks whether this approach is safe and helps patients do better overall.
ParisAges 18 years+ - NCT06287814Recruiting
Blood test to detect leftover cancer DNA in colorectal cancer patients
This study uses a simple blood test (liquid biopsy) to look for tiny bits of tumor DNA remaining after colorectal cancer surgery. It aims to see if the test can help predict whether the cancer will come back, especially in people with stage III cancer who will receive chemotherapy.
Montpellier, HéraultAges 18 years+ - 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+ - NCT06119867RecruitingPhase 3
Comparing colon cancer tissue checks from Europe and Japan
This trial compares two different methods of examining colon cancer tissue after surgery. It will help find the best way to check the cancer and guide future treatment.
MoscowAges Any age - NCT05524428Recruiting
Test to improve colorectal cancer screening at community clinics
This study tries to reduce barriers to colorectal cancer screening by using a repeated “test and improve” approach with clinic staff. If you work in roles that support screening at participating community health centers, you may be eligible to help implement and evaluate these changes.
Boston, MassachusettsAges 18 years+ - NCT05877456Enrolling by invitation
Checking a polyp-removal scoring tool for doctors
This study tests and confirms a scoring tool (GPAT) that helps describe how well doctors perform polyp removal during endoscopy. It may help standardize training and assessment, which can improve consistency in care.
Ghent, GentAges 18–100 - NCT05365412Recruiting
Study of colon cancer in younger adults
This study looks at the clinic and lab features of colon cancer in people diagnosed at a young age. Your information from your diagnosis and treatment may help doctors understand how colon cancer differs by age.
Seongnam-si, Gyeonggi-doAges 18 years+ - NCT05059444Recruiting
Blood test to catch cancer early after treatment
This study looks for signs of cancer left in the body after treatment using a simple blood test (called a liquid biopsy). It aims to see if the test can catch cancer that might come back earlier than regular scans.
Birmingham, AlabamaAges 18 years+ - NCT04920032RecruitingPhase 1
Blood test–guided extra treatment for colon cancer recurrence risk
This Phase 1 study uses a blood test called ctDNA to decide whether and how to adjust treatment in people with colon cancer who still have a small amount of disease left after surgery. If your blood test remains positive, the trial aims to reduce recurrence risk by guiding treatment changes.
Orange, CaliforniaAges 18 years+ - NCT04491929Recruiting
Radiation treatment for colon cancer in the liver using tiny beads
This trial studies a targeted liver radiation procedure that uses tiny radioactive beads to treat colon cancer spread mostly in the liver. It may help people whose liver tumors cannot be removed or treated with other common local treatments, but it has several safety and “screening” checks.
Aarhus N, DanmarkAges 18 years+ - NCT03841799Recruiting
Study of gut bacteria and immune changes in colon tissue
This study looks at how gut bacteria and immune activity differ in normal, pre-cancer, and cancer colon tissue. It may help researchers understand what changes in the body are linked to colon growth and how they could be targeted in the future.
