Recruiting studies
- NCT04516681RecruitingPhase 3
Ascorbic acid plus immunotherapy for spread colorectal cancer
This trial tests whether intravenous vitamin C (ascorbic acid) combined with an immune treatment (adebrelimab) can slow or shrink metastatic colorectal cancer that can’t be removed with surgery. It focuses on tumors that strongly show a specific marker called GLUT3, and aims to see if the combination works better than standard approaches.
Shanhai, Shanghai MunicipalityAges 18–75 - NCT04527861Recruiting
Minimally invasive single-incision surgery for colon cancer
This trial compares a single-incision laparoscopic operation versus the usual laparoscopic operation for colorectal (colon or “high rectum”) cancer. It looks at cancer outcomes and may help determine which approach is safer and works better for the right patients.
Lanzhou, GansuAges 18–85 - NCT04547166RecruitingPhase 2/Phase 3
New targeted immune drug plus bevacizumab and chemo for colon cancer
This trial studies serplulimab (an immune-related drug) together with bevacizumab and chemotherapy to treat metastatic colorectal (colon) cancer that cannot be removed with surgery. It aims to see whether this combination improves outcomes and is safe.
Guangzhou, GuangdongAges 18–75 - NCT04593407Recruiting
Check the best method to remove large flat colon polyps
This study compares two endoscopy techniques to remove large, flat-looking colon polyps. It aims to see which method removes the polyp more completely and safely.
MadridAges 18–85 - NCT04616495Recruiting
Liver transplant for colorectal cancer that can’t be removed
This trial studies liver transplantation for people with colorectal cancer that has spread to the liver but cannot be surgically removed. It aims to see if transplant can improve outcomes when the cancer is limited to the liver.
ValenciaAges 18–65 - NCT04680260RecruitingPhase 2
Personalized follow-up after limited surgery or radiation for colon cancer
This Phase 2 study tests the best way to choose and then follow treatment when colorectal cancer has spread only to a small number of spots. You may be eligible if your doctors can remove or precisely treat the spots and there’s no sign of additional spread on scans.
Aarhus NAges 18 years+ - NCT04687631RecruitingPhase 3
Study drug for colorectal cancer that spread to the liver
This Phase 3 trial tests a treatment approach for colorectal cancer that cannot be removed with surgery at first but has spread only to the liver. It is intended for people whose tumor is RAS/BRAF “wild-type” and who are well enough to do daily activities, to see if the treatment can control the cancer better.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04689347RecruitingPhase 1/Phase 2
New chemotherapy and targeted drug for a specific colon cancer type
This trial tests a combination of chemotherapy (5-FU/LV, irinotecan, and temozolomide) plus bevacizumab in metastatic colon or rectal cancer. It focuses on tumors with an “MGMT silenced” pattern (MGMT gene turned off), which may make some cancers more responsive to these medicines.
Milan, MilanAges 18–75 - NCT04714957Recruiting
Personalized study for cancer spread in the belly lining
This trial studies people whose cancer has spread to the lining of the abdomen (the “belly lining”), including cancers from the digestive tract or ovaries. You may be asked to join because the study aims to learn how to better match care to different patterns of this belly lining cancer spread.
LyonAges 18 years+ - NCT04716257Recruiting
Study of treatment outcomes in ovarian-spread colorectal cancer
This study follows women with colorectal cancer that has spread to the ovaries to see how care works in real life. It may help doctors understand which patients benefit most and how treatment choices affect outcomes.
Guangzhou, GuangdongAges 18 years+ - NCT04754672Recruiting
Exercise training to improve outcomes in advanced colon cancer
This trial studies whether supervised exercise—either aerobic fitness training or muscle-strength training—can improve outcomes for people with metastatic colorectal cancer. It compares which approach is most helpful and checks whether it’s safe during first-line chemotherapy.
's-HertogenboschAges 18 years+ - NCT04767568Recruiting
Testing a blood test to guide colorectal cancer screening care
This study looks at whether a simple blood test can help guide the care of people being evaluated for colorectal cancer. It may support earlier or clearer decision-making alongside existing screening or colonoscopy results.
BesançonAges 18 years+ - NCT04847063RecruitingPhase 1
Test drug heating inside the abdomen for peritoneal cancer
This Phase 1 trial tests a treatment that delivers heated chemotherapy directly into the abdomen (HIPEC) for certain cancers that have spread only within the abdominal lining. It aims to see how safely and effectively this approach works, especially when doctors can remove as much tumor as possible.
Bethesda, MarylandAges 18–120 - NCT04854213Recruiting
Study checks radiation effects in colon cancer lung-limited spread
This trial studies how targeted radiation (SBRT) affects cancer biology and immune cells in people with colon cancer that has spread only to a small number of lung nodules. Your tumor tissue will be analyzed to see what changes after treatment.
Naples, NAPOLIAges 18–80 - NCT04912765RecruitingPhase 2
New immune vaccine plus nivolumab for liver cancer
This trial studies whether an individualized “neoantigen” cancer vaccine given to immune cells (dendritic cells) plus nivolumab can improve outcomes in people with liver cancer and/or colorectal cancer that has spread only to the liver. It focuses on tumors that can be removed with curative surgery (with or without local ablation) and on people with good enough liver and overall health.
SingaporeAges 21 years+ - NCT04929223RecruitingPhase 1
Targeted drug study for metastatic colon or rectal cancer
This Phase 1 study tests targeted cancer treatments in people with metastatic colorectal cancer, using genetic “biomarker” results to match you to the right treatment group. It focuses first on safety, and also looks for early signs the treatment may work in specific tumor subgroups.
Birmingham, AlabamaAges 18 years+ - NCT06889610RecruitingPhase 2
Ablation plus drug therapy for advanced solid tumors
This trial tests combining a liver tumor ablation procedure with systemic drugs for people with advanced colorectal, breast, or melanoma cancer that has spread to the liver. The goal is to see if this approach can help when standard treatments have stopped working.
ShanghaiAges 18–80 - NCT06792695RecruitingPhase 2
Study of new treatments for colorectal cancer
This trial tests new treatment combinations for colorectal cancer that has spread (metastatic). It is for people whose cancer is mismatch repair proficient (pMMR) or microsatellite stable (MSS) and who have not had previous treatment for metastatic disease.
Scottsdale, ArizonaAges 18–130 - NCT04967183Recruiting
Compare a stool blood test versus colonoscopy follow-up after precancer removal
This study compares two ways of checking for colorectal cancer risk after advanced polyps are removed. It may help determine whether a stool test can safely replace some colonoscopy surveillance for certain people.
OurenseAges 50–65 - NCT05007132RecruitingPhase 2
First-line metastatic colon or rectal cancer study with targeted drugs
This Phase 2 trial compares two treatment combinations as a first treatment for metastatic (spread) colon or rectal cancer. It looks to see whether one combo works better or is safer than the other.
BerlinAges 18 years+ - NCT05008809RecruitingPhase 3
FIRE-9 trial: chemo after colon cancer metastasis removal
This trial studies whether giving chemotherapy after surgery or ablation (destroying spots of cancer) can improve outcomes in people with metastatic colon or rectal cancer. It compares post-treatment chemotherapy strategies to reduce the chance the cancer comes back.
AmbergAges 18 years+ - NCT05044689Recruiting
Study to find risk factors for breast and colon cancer
This study is trying to understand what factors might raise the risk of breast cancer and colon (large bowel) cancer. You may be enrolled either if you have a confirmed cancer diagnosis (cases) or if you do not have cancer (controls).
Ile-Ife, Osun StateAges Any age - NCT05051046Recruiting
Screening colonoscopy with hypnosis for colorectal cancer
This trial studies whether using hypnosis during a screening colonoscopy can help people better tolerate the procedure and complete it comfortably. It’s for adults who are scheduled for a routine screening colonoscopy and meet specific safety and communication requirements.
AngersAges 18–100 - NCT05068531Recruiting
Detecting early treatment failure in stage IV colon cancer
This study looks for early signs that treatment is not working in people with stage IV colon or rectal cancer that has spread only to the liver. It may help doctors adjust care sooner by using regular blood, stool, and tissue samples around liver procedures.
