Recruiting studies
- NCT07417358Recruiting
Single-stapled method for colorectal reconnection
This study compares a single-stapled method for reconnecting the colon after left-sided colorectal surgery. It aims to see if this technique works as well or better than the usual approach.
GothenburgAges 18 years+ - NCT06484153RecruitingPhase 2
New drug combo for advanced colorectal cancer
This trial tests a new combination of three drugs—fruquintinib (a targeted therapy), pirfenidone (an anti-fibrotic drug), and an immunotherapy (anti-PD-1)—for people with advanced colorectal cancer that has not responded to at least two prior treatments. The goal is to see if this triple therapy can shrink tumors more effectively than current options.
Wuhan, HubeiAges 18–75 - NCT07764497RecruitingPhase 2
Chemotherapy through liver artery for colorectal cancer that spread to liver
This trial tests giving chemotherapy directly into the liver artery for people whose colorectal cancer has spread only to the liver and cannot be surgically removed. The goal is to shrink the tumors and make the liver healthy enough for surgery.
Toronto, OntarioAges 18 years+ - NCT05612347Recruiting
Compare stool test vs colonoscopy for older adults with polyps
This study compares two ways to check for colon polyps in older adults: using a stool test versus having a colonoscopy. It may help find a simpler option if you only had a small number of lower-risk polyps before.
Birmingham, AlabamaAges 65–82 - NCT06957626Recruiting
Predicting polyp return after removal
This study aims to develop a tool using gut bacteria and metabolites to predict if high-risk colon polyps will come back after removal. If you are between 40 and 75 and have had certain types of colon polyps removed, you may be able to help us build better prediction methods.
BeijingAges 40–75 - NCT05334069Recruiting
Blood test study for early cancer detection in patients
This study collects blood from people with cancer and people without cancer (or with possible cancer) to test whether new blood tests can detect cancer earlier. Your blood samples help researchers evaluate how well these tests work.
Anchorage, AlaskaAges 40–75 - NCT05863195RecruitingPhase 3
Pump chemotherapy plus standard chemo for liver-only colorectal spread
This study tests adding a chemotherapy “pump” directly into the liver along with standard chemotherapy, compared with standard chemotherapy alone. It’s for adults with colorectal cancer that has spread to the liver but cannot be surgically removed, and who are responding to first chemotherapy.
Birmingham, AlabamaAges 18 years+ - NCT07705139Recruiting
Listening to bowel sounds after colorectal surgery
This study listens to your bowel sounds after colorectal cancer surgery to see if they can help doctors know when your gut is working again. You will have a small device placed on your belly to record sounds for a few days.
Wuhan, HubeiAges 18–90 - NCT04185779Recruiting
Colorectal cancer screening colonoscopy study
This study looks at patterns of colorectal (colon and rectum) findings in people who are having a colonoscopy as part of routine care. It may help improve how doctors detect and understand colorectal cancer and related growths over time.
South Shields, Tyne and WearAges 18 years+ - NCT04624555Recruiting
Check how well stool DNA tests help watch for colon cancer return
This trial studies whether an at-home stool DNA test (Mt-sDNA) can safely and usefully monitor people after colon or rectal cancer treatment. It’s mainly about whether the test is practical and helpful during routine follow-up.
Cleveland, OhioAges 18 years+ - NCT04812912Recruiting
Study sexual and reproductive effects in early colon cancer
This study looks at how early-onset colorectal cancer treatment affects reproductive and sexual health over time. It asks eligible people to complete questionnaires so researchers can understand and possibly improve care during and after treatment.
Basking Ridge, New JerseyAges 18–50 - NCT05286814RecruitingPhase 2
Pump-delivered therapy plus chemo for liver-metastatic cancers
This phase 2 study tests a liver-targeted medicine delivered through a special implanted pump, combined with standard chemo, for cancers that spread mainly to the liver. It may help control tumor growth in the liver and improve outcomes compared with standard treatment alone.
Bethesda, MarylandAges 18–120 - NCT05381792Recruiting
Test of gut bacteria changes after colon tumor removal
This study looks at how the gut’s bacteria and bacterial gene signals change after doctors remove certain advanced growths in the colon using endoscopy. If you need an endoscopic procedure for an advanced adenoma or early colon cancer, your stool/bacteria samples may help researchers understand what changes after treatment.
Shatin, New TerritoriesAges 18–90 - NCT05405673Recruiting
Test stool or tissue genes to find advanced colon growth
This study checks how well a set of bacterial gene markers (a DNA-like test) can help identify advanced “precancer-like” or higher-risk growths in the colon. It may help doctors better target who needs closer follow-up during colonoscopy.
Hong KongAges 18 years+ - NCT05592886Recruiting
Oral probiotic-and-prebiotic drink to prevent colon polyps returning
This study tests whether an oral synbiotic (a probiotic plus a prebiotic) can reduce the chance that advanced colon growths come back after they were removed. It also looks at changes in stool-related bacterial “gene markers” that may signal lower risk over time.
Hohhot, Inner MongoliaAges 18–90 - NCT05691491RecruitingPhase 1/Phase 2
Temozolomide plus M1774 for advanced metastatic cancers
This Phase 1/2 trial tests a combination of temozolomide and M1774 to see how safe it is and whether it can help shrink advanced cancers that have spread. It focuses on certain tumor types and specific biomarker results, and it may be an option if standard treatments have been tried or aren’t possible.
Irvine, CaliforniaAges 18 years+ - NCT05930496Recruiting
Exercise after colorectal cancer to change gut bacteria
This study tests whether a structured exercise program can improve the makeup of gut microbiota (gut bacteria) in people who have finished treatment for stage II–III colorectal cancer. It may help learn how exercise supports recovery, and it involves remote or in-person sessions with gut-focused tracking.
Seattle, WashingtonAges 18–70 - NCT06050447Recruiting
Study on treatment results for colorectal cancer
This study looks at factors that affect outcomes in people with colorectal cancer who have surgery as their main treatment. It aims to help doctors understand how to improve care.
Kaliningrad, Kaliningrad OblastAges 18 years+ - NCT06307548RecruitingPhase 1/Phase 2
Image-guided surgery and light therapy for colorectal cancer
This trial tests a special dye that helps surgeons see tumors more clearly during surgery, followed by a light therapy to destroy any remaining cancer cells. It is for people with advanced or returning colorectal cancer who are already scheduled for surgery.
Buffalo, New YorkAges 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 - NCT06452745Recruiting
Early colon cancer detection using a blood test
This study uses a simple blood test to find early signs of colorectal cancer in people who already had a positive stool test. If it works, it could help avoid unnecessary colonoscopies in the future.
Reus, TarragonaAges 50–70 - NCT06502704Recruiting
Bile acids and gut bacteria in early colorectal cancer
This trial studies how bile acids and gut bacteria are linked to early colorectal cancer. It may help identify patients at risk before cancer develops.
VilniusAges 18 years+ - NCT06522919RecruitingPhase 2
Immunotherapy and chemotherapy for advanced colorectal cancer
This trial tests a sequence of treatments for people with a specific type of advanced colorectal cancer (called pMMR or MSS) that has not responded to earlier therapies. Patients first receive an immunotherapy combination (pembrolizumab plus a personalized dendritic cell vaccine) followed by a chemotherapy pill (trifluridine/tipiracil) plus bevacizumab. The goal is to see if this sequence can help control the cancer.
Meldola, Forlì CesenaAges 18 years+ - NCT06637215Recruiting
Day surgery for colorectal cancer
This study tests whether a same-day surgery approach for colorectal cancer is safe and effective. It uses small incisions and special pain management to help you recover faster at home with a caregiver nearby.
