This trial uses a special MRI technique to help doctors better understand rectal cancer before treatment. It is for people who will receive chemotherapy and radiation before surgery.
TaoyuanAges 20 years+ - NCT07486570Recruiting
Stenting to prevent leaks after colon surgery
This trial tests if placing a small mesh tube (stent) in a major artery can prevent leaks where the colon is reconnected during surgery. It may help people who have a blockage in that artery but no symptoms from it.
Emmen, DrentheAges 40 years+ - NCT04087421RecruitingPhase 3
Transanal irrigation vs glycerol suppositories for LARS
This trial compares two ways to help bowel control in people with low anterior resection syndrome (LARS) after low rectal surgery. It aims to see which option works better when standard treatments have not helped enough.
AarhusAges 18 years+ - NCT04165772RecruitingPhase 2
Dostarlimab for locally advanced mismatch-repair deficient solid tumors
This Phase 2 trial studies dostarlimab (an immune therapy that targets PD-1) given before surgery or other initial treatment. It aims to shrink certain locally advanced cancers that have mismatch repair deficiency, potentially making treatment easier and improving outcomes.
Hartford, ConnecticutAges 18 years+ - NCT04666727Recruiting
Diet and gut microbiome study during screening colonoscopy
This study looks at how a person’s diet (vegetarian vs. omnivorous) affects the germs in the gut and related stool and tissue samples. You may be able to join if you’re getting a screening colonoscopy and meet lifestyle and medication requirements.
Houston, TexasAges 45 years+ - NCT04792684Recruiting
Collecting colon samples from adults with colon findings
This study collects body samples to help evaluate tests for people with suspected or newly diagnosed colorectal conditions, often around the time of colonoscopy or surgery. Depending on the arm, you may be asked to have a colonoscopy soon or to provide samples before planned surgery.
Chula Vista, CaliforniaAges 45–84 - NCT04896684Recruiting
Study collecting gut health information from adults’ scans
This study is looking at people who need an intestinal scope (endoscopy) for gut symptoms or bowel conditions like IBS, IBD, or possible colorectal cancer. Your results may help doctors better understand these long-term conditions and improve follow-up care.
ToulouseAges 18–99 - NCT04925154Recruiting
Study of decision-making for rectal cancer treatment
This study asks people newly diagnosed with rectal cancer about how they choose between treatment benefits and quality of life. It uses questionnaires to understand what tradeoffs matter to patients so care discussions can be improved.
Montreal, QuebecAges 18 years+ - NCT04999007Recruiting
AI tool to help surgeons decide during rectal cancer surgery
This trial tests an artificial-intelligence support tool that helps surgeons make decisions during surgery for rectal cancer. If you qualify, the tool may be used alongside the surgical team to support safer, more effective care.
Wuhan, HubeiAges 18–85 - NCT05049317Recruiting
Check urinary and sexual function after rectal cancer surgery
This study looks at how a specific rectal surgery (laparoscopic total mesorectum excision) affects urinary and sexual function after the operation. It may help patients by tracking what to expect and which factors relate to better recovery.
Wuhan, HubeiAges 18–70 - NCT05195710RecruitingPhase 1
Pre-surgery Y-90 treatment to grow future liver volume
This trial tests a radiation treatment called Y-90 given before liver surgery for colorectal cancer that has spread to the liver. The goal is to help the liver grow enough for safer, curative surgery, either right away or as part of a two-step operation.
Houston, TexasAges 18 years+ - NCT05234177Recruiting
Blood test to track colorectal cancer after surgery
This study looks at a blood “DNA” test to see if it can help monitor colorectal cancer after surgery. It may benefit you by improving how doctors track cancer during routine follow-up visits.
Fort Smith, ArkansasAges 18 years+ - NCT05254327RecruitingPhase 2
Radiation plus or minus BMX-001 for advanced rectal cancer
This Phase 2 study tests two different ways of giving radiation before surgery for locally advanced rectal cancer, with or without an added study drug called BMX-001. It aims to see whether the shorter/longer radiation plans and BMX-001 improve cancer control and are safe.
Lexington, KentuckyAges 18 years+ - NCT05404230Recruiting
Preventing nerve damage from oxaliplatin in the hands and feet
This study looks at ways to prevent numbness or nerve pain in the hands and feet that can happen from oxaliplatin treatment. It includes people with colon or rectal cancer who will be getting standard chemotherapy with capecitabine plus oxaliplatin.
AalborgAges 18 years+ - NCT05491434Recruiting
Study of muscle loss in colon cancer patients
This trial looks at muscle loss (called sarcopenia) in people with colon cancer to test an intervention that may help strength or recovery. If you’re age 70 or older and meet the cancer and health requirements, you may be able to take part.
L'Hospitalet de Llobregat, BarcelonaAges 70 years+ - NCT05495048Recruiting
Transvaginal surgery vs standard laparoscopy for right colon removal
This study compares two surgical approaches for removing the right side of the colon in certain women with colon cancer or a high-risk pre-cancer. It aims to see whether the less invasive transvaginal approach can be done safely and work as well as standard laparoscopic surgery.
ShanghaiAges 18–75 - NCT05768503RecruitingPhase 3
Test new drugs after colorectal cancer chemotherapy
This Phase 3 trial compares a new treatment combination (chidamide plus sintilimab plus bevacizumab) versus the standard second-line chemotherapy (FOLFIRI plus bevacizumab) for advanced colorectal cancer that is microsatellite stable/low. It aims to see which treatment works better and is safer for people whose cancer grew after first-line oxaliplatin-based therapy.
Hefei, AnhuiAges 18–75 - NCT05787197Recruiting
Blood test to guide treatment after colon cancer liver surgery
This trial studies a blood test (called ctDNA) in people with colon cancer that has spread to the liver and is being removed with curative surgery. The goal is to see how the blood test can help with planning and improving treatment after surgery.
BesançonAges 18 years+ - NCT05884723Recruiting
Ketogenic diet before liver surgery for fatty liver
This trial tests whether a ketogenic (very low-carb) diet before liver surgery can reduce fat in the liver. It is aimed at people with colorectal liver metastases who already have fatty liver seen on scans or biopsy.
London, OntarioAges 18 years+ - NCT05961969Recruiting
Robotic rectal surgery for early-to-mid rectal cancer
This trial tests a robotic, top-down approach to remove certain rectal tumors using an intersphincteric resection (a surgery that preserves bowel control as much as possible). It may help some people with stage I–III rectal cancer avoid a bigger operation and improve outcomes compared with standard surgical methods.
TaipeiAges 20–75 - NCT05963191Recruiting
Test camera bowel scan for early Lynch syndrome lesions
This study tests a special CAD-EYE system to help detect abnormal (potentially cancer-related) growths during colonoscopy in people with Lynch syndrome. It may improve how reliably clinicians find lesions early, when treatment can be easier.
ParisAges 18–90 - NCT05977621Recruiting
Ultrasound imaging to guide radiation needle placement
This trial tests a guidance technique that uses ultrasound images matched to MRI (a real-time “map”) to help track the needle position during treatment for cervical or uterine cancer. It may help make radiation treatments more precise for people who are getting curative-intent radiation with brachytherapy.
Durham, North CarolinaAges 18–90 - NCT06063928Recruiting

- Are there clinical trials for colorectal (colon or rectal) cancer?
- Yes. Clin2 currently lists 901 recruiting colorectal (colon or rectal) cancer 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 (colon or rectal) cancer 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 (colon or rectal) cancer 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.
