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+ - NCT06356714RecruitingPhase 2
Nocardia cell wall skeleton plus current therapy for colorectal cancer
This trial tests adding an investigational drug (Nocardia rubra cell wall skeleton) to the current treatment for people with advanced colorectal cancer that is stable but showing early signs of getting worse. It aims to see if this combination can help delay further progression.
Nanjing, JiangsuAges 18 years+ - NCT06449937Recruiting
Local liver treatment for colorectal cancer that has spread
This trial tests whether treating liver tumors with surgery or ablation can help people whose colorectal cancer has spread to the liver and other organs. It may be an option if you've had only 1 or 2 types of chemotherapy and your non-liver metastases are stable.
Chuzhou, AnhuiAges 18–80 - NCT06589830RecruitingPhase 2
TL938 with Trastuzumab for HER2+ Colorectal Cancer
This trial is testing a new combination of drugs (TL938 and trastuzumab) for people with a specific type of advanced colorectal cancer that is HER2-positive and RAS wild-type. It may offer a new option if you have already tried standard chemotherapy and a blood vessel-blocking drug.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06629051Recruiting
Long-term follow-up after berberine treatment trial
This study checks on people who took berberine in an earlier trial to see how they are doing 6 years later. It helps researchers understand the long-term effects of the treatment.
ShanghaiAges Any age - NCT07224724Recruiting
Exosome liquid biopsy for colorectal cancer spread
This study uses a blood test to detect if colorectal cancer that has spread to the liver has also spread to other parts of the body. It may help doctors better understand how the cancer is moving and guide treatment decisions.
Duarte, CaliforniaAges 18 years+ - NCT06734156Recruiting
Gut microbiome study in colorectal cancer patients
This study looks at how bacteria and other microbes in your gut are linked to colorectal cancer risk and outcomes. By collecting stool samples from people newly diagnosed with colorectal cancer, researchers hope to find patterns that could improve understanding and future treatments.
Lisbon, Lisbon DistrictAges 40–74 - 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.
