Testing BAY 3771249 for Advanced Colorectal Cancer With KRAS Mutation
This early-stage study tests a new drug called BAY 3771249 in people with advanced colorectal cancer that has a specific genetic change (KRAS G12D mutation). Researchers want to learn if it's safe and whether it helps shrink tumors.
Phoenix, ArizonaAges 18 years+ - NCT06157463Recruiting
FAPI imaging for newly diagnosed rectal cancer
This trial tests a new imaging agent called 68Ga-FAPI to see how well it finds rectal cancer and guides treatment. It's for people with new stage II or III rectal cancer who are about to start neoadjuvant therapy (treatment before surgery).
TaoyuanAges 18 years+ - NCT04824053Recruiting
Dairy products study for people at high risk of colon cancer
This trial studies whether specific dairy products (UNICLA-A2) can help lower the risk of future colon problems in people considered high risk for colorectal cancer. You may be asked to keep using dairy consistently and undergo colon checks as part of usual follow-up.
Zaragoza, ZaragozaAges 18–80 - NCT06364371Recruiting
Predicting rectal cancer treatment response using multi-omics
This trial is testing a new way to predict how well your rectal cancer will respond to treatments given before surgery. It uses advanced tests (like looking at genes and other markers) to tailor your care.
Guangzhou, GuangdongAges 18–80 - NCT06312982RecruitingPhase 2/Phase 3
Chemo, radiation, and immunotherapy before rectal cancer surgery
This trial tests whether a combination of chemotherapy, radiation, and an immunotherapy drug (tislelizumab) before surgery can improve outcomes for people with locally advanced rectal cancer that has specific protein/gene markers (pMMR or MSS). It’s designed for those who have not yet had any treatment for their cancer.
Beijing, Beijing MunicipalityAges 18–75 - NCT06279299Recruiting
Lymph node removal for rectal neuroendocrine tumors during laparoscopic surgery
This trial tests whether removing lymph nodes in the pelvis during laparoscopic surgery for rectal neuroendocrine tumors (a type of slow-growing or aggressive tumor) improves outcomes. It is for people with larger or recurrent tumors, or those at higher risk due to tumor grade or depth.
Beijing, Beijing MunicipalityAges 18–75 - NCT06477991Recruiting
No surgery after immunotherapy for MSI-H colorectal cancer
This trial is studying whether some people with a specific type of advanced colorectal cancer (MSI-H/dMMR) might be able to skip surgery after immunotherapy. Doctors will use a blood test (MRD monitoring) to track the cancer, and then decide whether to keep an eye on it or operate.
Kunming, YunnanAges 18–75 - NCT06521866RecruitingPhase 2
Study of serplulimab plus standard therapy for advanced colorectal cancer
This trial tests an immunotherapy drug (serplulimab) combined with targeted therapy, chemo, and radiation as a first treatment for people with advanced colorectal cancer that has spread and cannot be surgically removed. It aims to see if this combination can help control the cancer.
Fuzhou, FujianAges 18 years+ - NCT07172282RecruitingEarly Phase 1
Immunotherapy for colorectal cancer liver metastases
This trial tests a new way to deliver immunotherapy directly into the liver for people with colorectal cancer that has spread only to the liver. The goal is to see if this approach can shrink tumors before surgery, and it may be an option if you've already had standard chemotherapy.

Check a new alternative to ileostomy after bowel surgery
This trial tests whether a device called COLO-BT can be a safer, effective alternative to an ileostomy (a temporary or longer-term opening from the intestine to the skin). It’s for certain adults having a bowel connection low in the pelvis, where leak risk matters.
Buffalo, New YorkAges 19–80 - NCT05174169RecruitingPhase 2/Phase 3
Adjuvant colon chemotherapy guided by tumor DNA results
This trial tests whether treatment for colon cancer after surgery can be guided by a blood test that looks for leftover cancer signals (ctDNA). It may help some people choose stronger or different chemo based on whether ctDNA is found after surgery.
Birmingham, AlabamaAges 18 years+ - NCT05253651RecruitingPhase 3
Tucatinib plus trastuzumab with chemo for HER2+ metastatic colon cancer
This trial tests whether adding tucatinib and trastuzumab to standard chemotherapy works better than standard treatment alone for people with HER2-positive metastatic colon or rectal cancer. It aims to improve how long people live and how well tumors respond as first treatment for advanced disease.
Glendale, ArizonaAges 18 years+ - NCT02966483Recruiting
