Recruiting studies
- NCT06957236Enrolling by invitation
NICE Procedure for Benign Colon Disease
This trial tests a new minimally invasive surgery called the NICE procedure for treating benign left-sided colon diseases like diverticulitis or benign polyps. It aims to see if this approach leads to fewer infections and better recovery compared to standard surgery.
Houston, TexasAges 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+ - NCT06940947RecruitingPhase 3
Endoscopy or surgery for early colon cancer
This trial compares a newer, less invasive endoscopic procedure with standard surgery for people who have a small, early-stage colon cancer. The goal is to see if the endoscopic treatment is as effective as surgery while being gentler on the body.
GdanskAges Any age - 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 - NCT06923787RecruitingPhase 2
Lidocaine for colon cancer surgery recovery
This trial tests whether giving lidocaine through an IV during and after colon cancer surgery can help with recovery and boost your immune system. It's for people having laparoscopic colon surgery who haven't had chemotherapy before.
LjubljanaAges 18–80 - 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 - 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 - NCT06830239RecruitingPhase 2
Neoadjuvant dostarlimab for resectable stage III colon cancer
This trial tests an investigational immunotherapy drug called dostarlimab given before surgery for colon cancer. It is for people whose tumor is MMR-proficient (also called MSS) and is large enough or has spread to nearby lymph nodes but not to other parts of the body. The goal is to see if this treatment can shrink the tumor before surgery.
LeuvenAges 18 years+ - NCT06805994RecruitingPhase 1
Restoring infant nose bacteria after staph treatment
This study tests whether giving a nasal spray of healthy bacteria to infants can restore good germs in the nose after they receive mupirocin ointment to treat Staph aureus. It aims to bring back a healthy nasal microbiome.
Baltimore, MarylandAges birth–60 years - NCT06802991Recruiting
Optimized post-discharge care for older colon cancer patients
This trial tests better nutrition and follow-up care for older patients after colon cancer surgery. It focuses on people who are somewhat frail and at risk for poor nutrition, to see if extra support at home can improve recovery.
HerlevAges 65 years+ - NCT06731894RecruitingPhase 2
Cannabis for nerve pain after chemotherapy in breast and colon cancer survivors
This trial tests whether a cannabis-based product can reduce nerve damage (neuropathy) caused by chemotherapy in people who have finished treatment for breast or colon cancer. It focuses on survivors who still have pain, numbness, or tingling in their hands or feet.
Duarte, CaliforniaAges 18 years+ - NCT06686576RecruitingPhase 3
Study of QL1706 before surgery for MSI-H colon cancer
This trial tests a new immunotherapy medicine (QL1706) given before surgery to treat colon cancer that hasn't spread yet. It's designed for patients whose tumors have a specific gene feature (MSI-H/dMMR) and who haven't had any prior treatment for this cancer.
GuangzhouAges 18–75 - NCT06567782RecruitingPhase 2
Immunotherapy plus chemotherapy vs. chemotherapy alone for stage 3 colon cancer
This trial tests whether adding the immunotherapy drug dostarlimab to standard chemotherapy (CAPEOX) is more effective than chemotherapy alone for people with a specific type of colon cancer (MMRp/MSS) that has not spread. It is given before surgery to shrink the tumor.
AalstAges 18 years+ - NCT06580574RecruitingPhase 2
Immunotherapy to save the stomach or colon from surgery
This trial tests whether using immune checkpoint inhibitors alone (like checkpoint blockade drugs) can help people with certain gastric or colon cancers avoid surgery. It's for patients whose tumors have a specific genetic feature called dMMR/MSI-H and haven't spread to other parts of the body.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06490536RecruitingPhase 3
Testing a new treatment for high-risk colon cancer after surgery
This trial tests a new treatment approach for people with certain high-risk colon cancers (stage II or III in the upper colon) after surgery. It aims to see if adding a study drug can help prevent the cancer from coming back.
BerlinAges 18 years+ - NCT05713903Recruiting
Compare keyhole versus open surgery for right colon cancer
This trial compares two surgical approaches—keyhole surgery versus open surgery—for right colon cancer. It aims to see which approach works better and is safer for patients needing planned (elective) tumor removal.
LarissaAges 18–90 - NCT06329102Recruiting
Right colon cancer surgery and specimen quality study
This trial is studying how the type and method of surgery for right-sided colon cancer affects the quality of the removed tissue. It aims to improve surgical techniques for this type of cancer.
BergenAges 18–99 - NCT06434896Recruiting
Blood test to guide chemotherapy in stage II colon cancer
This trial is for people with stage II colon cancer who are not currently getting chemotherapy. It uses a blood test to look for tumor DNA, so doctors can decide if chemotherapy might help prevent the cancer from coming back.
's-HertogenboschAges 18 years+ - NCT06368141RecruitingPhase 2
Chemo plus immunotherapy before surgery for colon cancer
This trial tests whether giving chemotherapy followed by an immunotherapy drug (a checkpoint inhibitor) before surgery helps shrink locally advanced colon cancer. It is for people with a specific tumor type (MSS and RAS mutation) who have not had prior treatment.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06370884RecruitingPhase 1
Gut bacteria transplant after colon surgery
This study tests whether transplanting healthy gut bacteria into people who have had part of their colon removed can improve recovery. It may help prevent infections or other complications after surgery.
Minneapolis, MinnesotaAges 18–75 - NCT05186116Recruiting
Liver transplant for colon cancer that cannot be removed
This trial studies whether liver transplant (rather than removing the liver tumors) can help some people with colon or rectal cancer spread to the liver. It’s meant for people whose cancer has responded or stayed controlled on standard treatments and who have no cancer outside the liver.
Modena, MOAges 18–77 - NCT06107920RecruitingPhase 3
Chemotherapy before surgery for blocked colon cancer
This trial tests whether giving chemotherapy before surgery helps people with colon cancer that caused a blockage and needed a temporary colostomy. It aims to improve outcomes compared to standard treatment.
AmiensAges 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 - NCT06077435Recruiting

Common questions
- Are there clinical trials for colonization?
- Yes. Clin2 currently lists 436 recruiting colonization studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a colonization 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 colonization 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.
