Recruiting studies
- NCT05970133Recruiting
Robotic surgery vs laparoscopy for left colon cancer
This trial compares two ways to remove left-sided colon cancer and take the specimen out through the anus (without a large external incision). It may help find which approach is safer and more effective for curing Stage I–III disease.
TaipeiAges 18 years+ - NCT05970705RecruitingPhase 2
Regorafenib plus TAS-102 versus regorafenib alone for advanced bowel cancer
This Phase 2 study tests whether adding TAS-102 to regorafenib works better than regorafenib by itself for metastatic colorectal cancer after at least one prior treatment has stopped working. It aims to improve how long the cancer can be controlled for patients in later treatment lines.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05994482Recruiting
Surveillance colonoscopy study in older veterans
This study looks at how often older veterans (age 75 and older) should get a follow-up colonoscopy after having polyps removed. Researchers will review medical records and talk to patients and doctors to help create better guidelines for surveillance colonoscopies in older adults.
San Diego, CaliforniaAges 75 years+ - NCT05999370Recruiting
Pre-surgery exercise and nutrition for older colorectal cancer patients
This trial tests whether exercise and nutrition support before surgery can help older colorectal cancer patients who are weak or malnourished. If you are 65 or older, scheduled for colorectal cancer surgery, and have trouble walking or eating well, this study may be for you.

PD-1 immunotherapy with or without chemo before surgery for colorectal cancer
This trial tests a medicine called PD-1 (a type of immunotherapy that helps your immune system fight cancer), sometimes with chemotherapy, before surgery for a certain type of colorectal cancer. It is for people whose tumors have a specific DNA repair problem (dMMR or MSI-H) and whose cancer has not spread to distant organs.

Guangzhou, GuangdongAges 18–75 - NCT06018961Recruiting
Study of bowel slowdown after digestive surgery
This study is looking at how common and severe a condition called 'postoperative ileus' (temporary slowdown of the bowel) is after planned digestive tract surgeries. It will help doctors better understand and manage this complication.
ToulouseAges 18 years+ - NCT06024837Recruiting
Testing spectral CT for colorectal cancer spread to liver or belly
This study tests a new type of CT scan (spectral CT) to see how well it detects colorectal cancer that has spread to the liver or belly lining. It may help doctors better plan surgery to remove all the cancer.
Saint-EtienneAges Any age - NCT06026410RecruitingPhase 1
KO-2806 for advanced solid tumors
This trial tests a new drug called KO-2806, alone or with other treatments, for people with advanced solid tumors that have specific gene changes (like HRAS or KRAS mutations). It may help if standard treatments have stopped working.
Phoenix, ArizonaAges 18 years+ - NCT06033976Recruiting
Registry for endoscopic removal of digestive tract growths
This study collects information on people who are having a procedure called endoscopic submucosal dissection to remove abnormal growths in the digestive tract. It helps doctors learn more about how well the procedure works and who benefits most.
BucharestAges 18–100 - NCT06037954Recruiting
Mental health support for older adults with cancer
This study offers mental health care for older adults (65+) with breast, colorectal, lung, or prostate cancer who are getting treatment or recently finished. It aims to help people who are also feeling depressed.
New York, New YorkAges 65 years+ - NCT06040541RecruitingPhase 1
Study of RMC-9805 for KRAS G12D solid tumors
This trial tests an experimental pill (RMC-9805) for people with solid tumors that have a specific KRAS G12D mutation. It's for those who have already tried other treatments and need new options.
Sacramento, CaliforniaAges 18 years+ - NCT06043466RecruitingPhase 1
CAR-T cell therapy for CEA-positive advanced solid tumors
This trial tests a new cell therapy called CAR-T that targets cancer cells with a protein called CEA. It is for people with certain advanced cancers that have not responded to standard treatments.
Hangzhou, ZhejiangAges 18 years+ - NCT06055439RecruitingPhase 1/Phase 2
CAR T cell therapy for GI cancers
This trial tests a new type of immunotherapy called CAR T cells that target a protein (CDH17) found on certain stomach, colon, and rectal cancers. It's designed for people whose cancer has spread and has been treated before.
Atlanta, GeorgiaAges 18–85 - NCT06057350Recruiting
Surgery versus endoscopy for early colon cancer with uncertain margins
This trial compares surgery versus an endoscopic procedure for people who had a colon polyp removed but some cancer cells may still be present at the edges. The goal is to see which approach leads to better outcomes and fewer side effects for early-stage colon cancer.
Oslo, AkershusAges 40 years+ - NCT06059963Recruiting
Simple blood test for colorectal cancer screening
This study is testing a new blood test (Signal-C) to see if it can help find colorectal cancer early. You may be able to join if you are average risk and getting a routine screening colonoscopy.
Raonoke, VirginiaAges 45–84 - NCT06063928Recruiting
Cancer support study for Hispanic patients
This study explores how community support affects Hispanic people with colon or rectal cancer. You provide a tumor sample and answer questions to help researchers learn how to better support patients like you.
Los Angeles, CaliforniaAges 18 years+ - NCT06077591Recruiting
Genetic and organoid testing to guide cancer treatment
This trial uses advanced testing (genetic sequencing and lab-grown tumor models) to find the best treatment for people with advanced solid tumors that haven't responded to at least one standard treatment. The goal is to personalize therapy based on your tumor's unique features.
Hong Kong, N.T.Ages 18–100 - NCT06117241Recruiting

New drug combo and radiation for advanced colorectal cancer
This trial tests a new combination of drugs (cadonilimab, fruquintinib) plus targeted radiation (SBRT) for people with advanced MSS colorectal cancer who have already tried several standard treatments. The goal is to see if this combination can help shrink tumors or slow disease progression.

MRD-guided Chemo Timing for Early Colon Cancer
This trial is for people with early-stage colon cancer (stage II high-risk or stage III low-risk) that is not MSI-H. It uses a blood test (MRD) to see if you can safely delay or skip extra chemotherapy after surgery, based on whether the test finds any leftover cancer cells.

Common questions
- Are there clinical trials for colorectal?
- Yes. Clin2 currently lists 1,211 recruiting colorectal 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 colorectal 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 colorectal 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.
