Recruiting studies
- NCT06741293Recruiting
Improving colorectal cancer early screening with stool tests
This study looks for markers in stool (poop) to detect colorectal cancer early. If you are between 40 and 74, live in the Lisbon area, and don't have certain digestive or cancer conditions, you may help improve screening by providing a stool sample.

This study looks at how well a type of drug called an immunomodulator, given together with other cancer treatments, works for people with colorectal cancer. It aims to see if combining these therapies can improve outcomes.
TaichungAges 20 years+ - NCT05950503Recruiting
MRI to assess liver spread from colon cancer
This trial studies how well MRI can evaluate liver metastases (spread to the liver) from colorectal cancer. If you have measurable liver lesions, your MRI results may help doctors better track and plan care.
RomaAges 18–85 - NCT06529523RecruitingPhase 2
Testing tislelizumab for dMMR colorectal cancer
This trial tests the immunotherapy drug tislelizumab for people with a specific type of colorectal or rectal cancer called dMMR. It aims to see if this treatment can shrink tumors or improve outcomes in patients who haven't had many other treatments.
New York, New YorkAges 18 years+ - NCT06434376Enrolling by invitationEarly Phase 1
Personalized immune therapy for ctDNA-positive colorectal cancer
This trial tests a personalized immune therapy (like a custom vaccine) for people with colorectal cancer that has a positive ctDNA MRD test after surgery. It aims to use the body's own immune system to target any remaining cancer cells and prevent the cancer from coming back.
Wenzhou, ZhejiangAges 18–80 - NCT06371768Recruiting
Helping Young Cancer Survivors Manage Symptoms & Transition to Care
This study is designed to help adolescent and young adult cancer survivors manage symptoms and smoothly transition to post-treatment care. If you finished treatment for certain cancers within the past 1 to 5 years, you may be able to join.
Durham, North CarolinaAges 18–39 - NCT06369259RecruitingPhase 2
Combination treatment for advanced colorectal cancer that resisted standard therapy
This clinical trial tests a new combination of three drugs for people with advanced colorectal cancer that has not responded to standard anti-EGFR treatments. The goal is to see if this combination can shrink tumors or slow the cancer down.
Houston, TexasAges 18 years+ - NCT06353854Recruiting
Study of biomarkers in MSI-high colorectal cancer patients on immunotherapy
This trial is studying people with a specific type of advanced colorectal cancer (MSI-high/dMMR) who are starting immunotherapy with pembrolizumab. The goal is to find out which markers in the tumor might predict whether the treatment works well.
BayonneAges 18 years+ - NCT06342440Recruiting
Early detection of colon cancer and advanced polyps
This study aims to find colorectal cancer and advanced polyps (adenomas) earlier by looking at blood samples. Researchers hope a simple blood test might one day help detect colon cancer before it spreads.
Monrovia, CaliforniaAges 18 years+ - NCT06336902RecruitingPhase 1
Immunotherapy plus fasting diet and vitamin C for KRAS-mutated colorectal cancer
This trial tests a combination of two immunotherapy drugs (botensilimab and balstilimab) plus a fasting-mimicking diet and high-dose vitamin C for people with a specific type of advanced colorectal cancer (KRAS-mutated). It aims to see if this approach can help when standard treatments have stopped working.
Fullerton, CaliforniaAges 18 years+ - NCT06333392Recruiting
Underwater colonoscopy for better cancer screening
This trial tests if a new type of colonoscopy called total underwater colonoscopy (TUC) is better at finding polyps and cancer during routine screening. If you had a positive FIT stool test and are scheduled for a follow-up colonoscopy, you may be able to join.
DrammenAges 55–60 - NCT06300463RecruitingPhase 2
Immunotherapy combinations for colorectal cancer with liver tumors

Common questions
- Are there clinical trials for colorectal cancer (diagnosis)?
- Yes. Clin2 currently lists 354 recruiting colorectal cancer (diagnosis) 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 cancer (diagnosis) 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 cancer (diagnosis) 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.
