Understanding Treatment Resistance in BRAF-Mutated Colorectal Cancer
This study looks at why some people with a specific type of colorectal cancer (BRAF V600E-mutated) stop responding to targeted drugs over time. Researchers will take small tissue samples before and during your treatment with anti-EGFR antibody and BRAF inhibitor to understand resistance and help improve future treatments.
AarauAges 18 years+ - NCT06948448RecruitingPhase 2
New treatment for advanced colorectal cancer with PD-L1 biomarker
This trial tests a new drug (ONO-4578) combined with standard chemotherapy and immunotherapy for people with advanced colorectal cancer that has not been treated before and has a specific marker called PD-L1. The goal is to see if this combination works better than the usual treatment.
Phoenix, ArizonaAges 18 years+ - NCT07705880Recruiting
Predicting cancer in large flat colon polyps
This study tests a new tool to help doctors decide if a large, flat colorectal polyp might contain cancer. It involves doctors who use the tool during colonoscopy to better guide treatment.
GhentAges 18 years+ - NCT02997293Recruiting
Enhanced recovery after colorectal surgery care program
This study looks at whether a structured “enhanced recovery” plan around the time of colorectal surgery improves outcomes. Because it focuses on a specific group of surgeries done at a specific hospital during certain dates, it may be mainly for people whose surgeries match those records.
Little Rock, ArkansasAges 18 years+ - NCT03303833Recruiting
Lynch syndrome study following people over time
This study follows adults with Lynch syndrome (an inherited gene change) using regular questionnaires and tracking health over time. It may help researchers understand how the condition progresses and improve care for people with these gene mutations.
WageningenAges 18–80 - NCT03349762Recruiting
Huaier granules to help prevent colorectal cancer coming back
This study tests whether Huaier granules after surgery can lower the chance that colorectal cancer returns or spreads. It is for people who have recently had “radical” (complete) surgery for certain stages of colorectal cancer and are within about 2 months of that surgery.
Shijiazhuang, HebeiAges 18–75 - NCT03401294RecruitingPhase 2
Turn unresectable liver cancer into operable colorectal cancer
This Phase 2 study tests a treatment strategy to shrink or control colorectal cancer that has spread only to the liver, with the goal of making it removable by surgery. If you qualify, it may offer a chance to move from “not operable” to “operable,” but it’s still experimental.
Regina, SaskatchewanAges 18–70 - NCT03494946Recruiting
Liver transplant vs chemotherapy for colon cancer liver spread
This trial compares liver transplantation to standard chemotherapy for people with colon or rectal cancer that has spread to the liver but cannot be removed surgically. It looks at whether transplant can help patients live longer or better than chemotherapy in the right patients.
OsloAges 18 years+ - NCT03659448RecruitingPhase 3
Test drug that helps map colon and rectal cancer during surgery
This Phase 3 study tests SGM-101, a drug used during surgery to help doctors better outline primary, recurrent, and spread (metastatic) colorectal cancer. It may improve how completely tumors are identified and removed during an operation.
Duarte, CaliforniaAges 18 years+ - NCT03841799Recruiting
Study of gut bacteria and immune changes in colon tissue
This study looks at how gut bacteria and immune activity differ in normal, pre-cancer, and cancer colon tissue. It may help researchers understand what changes in the body are linked to colon growth and how they could be targeted in the future.
Lyon, LyonAges 18 years+ - NCT03874026RecruitingPhase 2
Folfiri plus cetuximab for advanced, gene-matched colon cancer
This trial tests whether a combination chemotherapy (Folfiri) plus cetuximab works better for people with stage IV colorectal cancer that has specific tumor gene markers and a specific blood-gene type. It may help you shrink tumors or control the cancer if you match the study’s required lab and health criteria.
NaplesAges 18–75 - NCT03919461RecruitingPhase 2
Preventing colon and rectal cancer spread after surgery
This Phase 2 study tests medicines given around the time of colon or rectal cancer surgery to help lower the chance the cancer will later spread to other parts of the body. If you are planned for curative (potentially curable) surgery and have no signs of spread yet, the trial may help prevent future metastases.
AfulaAges 20–80 - NCT03926338RecruitingPhase 2
Before-surgery immunotherapy for MSI-H or dMMR colon cancer
This trial studies a treatment given before surgery using toripalimab, with or without celecoxib, for colon or rectal cancer that has MSI-H or dMMR tumor features. It aims to shrink or control the cancer before the operation and compare whether adding celecoxib helps.
Guangzhou, GuangdongAges 18–75 - NCT03941080Recruiting
Study gut bacteria changes in advanced colorectal cancer
This study looks at how gut bacteria (the microbiome) change during treatment for colorectal cancer that has spread or cannot be removed. Researchers hope the findings may help improve understanding of how treatment works and how to tailor care.
AssenAges 18 years+ - NCT03957902RecruitingPhase 2
Aspirin blood markers to guide prevention after colon cancer
This Phase 2 trial studies how aspirin affects specific “biomarkers” (measurable body signals) in people newly diagnosed with colon or rectal cancer. The goal is to see whether aspirin-related changes can help design more personalized prevention treatment plans.
Zaragoza, ZaragozaAges 18–79 - NCT03972956Recruiting
Collecting samples during cancer or surgery visits
This trial looks at collecting (taking) medical samples from people who need surgery for colorectal cancer, stomach (gastric) cancer, or a non-cancer condition. It may help researchers better understand these diseases and improve how treatment is planned.
Wuhan, HubeiAges 18–80 - NCT03998202Recruiting
Study of chemotherapy side effects in older colorectal cancer patients
This study looks at how chemotherapy and immunotherapy affect the body in older adults with colorectal cancer, especially early side effects. It may help researchers understand why some people lose strength and how to better predict and manage treatment toxicity.
Millville, DelawareAges 60 years+ - NCT04008407Recruiting
Monitoring outcomes after removing certain colon growths
This study follows patients who are having surgery to remove a specific type of flat colon growth. It aims to see how safe and effective a “selective” approach is, based on what the growth looks like and your situation.
Westmead, New South WalesAges 18 years+ - NCT04014530RecruitingPhase 1/Phase 2
Testing pembrolizumab plus ataluren for metastatic dMMR or pMMR cancer
This early-phase trial tests pembrolizumab combined with ataluren for people with metastatic colorectal cancer that has either dMMR or pMMR, and for metastatic dMMR endometrial cancer. The goal is to see whether this combination can shrink tumors or improve outcomes for cancers with specific mismatch repair (MMR) features.
Amsterdam, North HollandAges 18 years+ - NCT04050345Recruiting
Blood test to spot DNA changes after early colon cancer surgery
This study checks a “cell-free tumor DNA” blood test to see if cancer mutations can predict relapse after surgery for early colorectal cancer. If results look risky, they may help guide closer follow-up and future treatment decisions.
Milton Keynes, BuckinghamshireAges 18 years+ - NCT04130971Recruiting
Testing tumor tissue to understand and predict colorectal cancer response
This study looks at tissue samples from people with colorectal cancer to better understand tumor features and how they may respond to treatment. If you have colorectal cancer, the trial may help researchers match future treatments more effectively.
GothenburgAges 18 years+ - NCT04490733Recruiting
Test dual-task walking to improve thinking in colorectal cancer
This study looks at a walking exercise that makes you do two tasks at once (for example, walking while focusing on something) to see if it can improve thinking and memory. It is for people newly diagnosed with early to mid-stage colorectal cancer, and excludes people with other cancers or cancer coming back.
TaipeiAges 40–75 - 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
