Recruiting studies
- NCT07432399RecruitingPhase 2

This study tests whether giving lidocaine or a high-dose steroid before colon cancer surgery can improve immune function and recovery. The goal is to find a simple, safe way to help your body respond better during surgery.
LjubljanaAges 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.
Montpellier, HéraultAges 18 years+ - 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 - NCT07407465RecruitingPhase 2
Study of a new drug combo for advanced HER2-positive colorectal cancer
This trial tests a combination of three drugs (trastuzumab deruxtecan, capecitabine, and bevacizumab) as the first treatment for people with HER2-positive colorectal cancer that has spread or cannot be removed by surgery. The goal is to see if this combination can shrink tumors and help patients live longer.
LyonAges 18 years+ - NCT05257135Recruiting
Study database and blood samples for colon cancer cachexia
This study collects clinical information and planned blood samples to better understand “cachexia,” which is a serious wasting condition that can happen with advanced cancer. It may help doctors find better ways to predict and manage symptoms in people with colon cancer who can’t have surgery.
MontpellierAges 18 years+ - NCT07405931Recruiting
Managing chemo side effects with phone calls and a smartphone app
This study tests whether checking in by phone or smartphone app can help manage chemotherapy side effects. If you are starting a new chemo for stomach, lung, breast, or colon cancer, this program may support you from home.
BusanAges 19 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 - NCT07314996Recruiting
Laparoscopic vs. open surgery for colon cancer with belly fat
This trial compares laparoscopy (minimally invasive) and open surgery for treating colon cancer in people with extra belly fat around internal organs (visceral obesity). The goal is to see which approach gives better recovery and outcomes.
Hangzhou, ZhejiangAges 18–75 - NCT07279077RecruitingPhase 2
Low-dose radiation with chemo and immunotherapy for high-risk colon cancer
This trial tests a combination of low-dose radiation, chemotherapy, and an immunotherapy drug (PD-1 inhibitor) for people with a specific type of high-risk colon cancer that has not spread. The goal is to see if this approach can shrink the tumor before surgery and improve outcomes.
Guangzhou, GuangdongAges 18–75 - NCT07272772RecruitingPhase 2/Phase 3
FAPI-PET scan for colon cancer diagnosis
This trial tests a new type of PET scan (FAPI-PET) to see if it can better find colon cancer that has spread to lymph nodes or other parts of the body. It may help doctors plan the right treatment for you.
TurkuAges 18–85 - NCT05041478Recruiting
Cold removal method for large colon polyps
This trial compares two cold endoscopic techniques to remove certain large, non-cancerous colon polyps with better control of bleeding and leftover tissue. You may be offered one of the two removal methods during your scheduled colonoscopy.
Westmead, New South WalesAges 18 years+ - 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+ - NCT06293625RecruitingPhase 3
Chemotherapy before surgery for colon cancer in older adults
This trial tests whether giving 6 weeks of chemotherapy (FOLFOX) before surgery can help people aged 70 and older with locally advanced colon cancer. It aims to make treatment safer and more effective for older adults.
DijonAges 70 years+ - NCT07255729Recruiting
Blood Test for Colon Cancer Staging
This study looks at a new blood test that may help doctors better understand how far colon cancer has spread. By testing a sample of your blood (taken before surgery), researchers hope to find patterns that predict the stage of cancer and help guide treatment decisions.
Duarte, CaliforniaAges 18 years+ - 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+ - 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 - NCT07098182Recruiting
Preserving blood supply during colon or rectal surgery
This trial tests a technique during colon or rectal surgery to preserve a specific blood vessel (the left colic artery) that helps keep the remaining colon healthy. It is for people with left colon, rectal, or ovarian cancer who are scheduled for surgery.
Montpellier, HeraultAges 18 years+ - NCT07088926RecruitingPhase 2
Study of a new drug for bronchiectasis with chronic pseudomonas infection
This study tests an investigational drug given through an IV to see if it can reduce lung infections and flare-ups in people with bronchiectasis who have a chronic pseudomonas infection. Participation may help improve symptoms and quality of life.
Orange, CaliforniaAges 12 years+ - 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 - NCT07083076Recruiting
Regular diet vs low residue diet after colon surgery
This study compares a regular diet to a low residue diet (a diet low in fiber) after colon surgery to see if patients can eat normally without issues. It may help determine if a regular diet is safe and better for recovery.
Manhasset, New YorkAges 18 years+ - NCT06958926Recruiting
Study of colon cancer that returns after surgery
This study looks at colon cancer that comes back in the same area after surgery. It may help doctors understand how to better treat this type of recurrence.
HsinchuAges 18 years+ - NCT07046468Recruiting
Smart pill to check gut health in colon inflammation and cancer
This trial tests a smart pill that measures gut health in people with colon inflammation (ulcerative colitis) or colon cancer. It aims to see if the pill can help doctors better understand how the gut is working during treatment or before surgery.
Nijmegen, GelderlandAges 18 years+ - NCT07041229Enrolling by invitation

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.
