Recruiting studies
- NCT01479608Recruiting
Liver transplant for colon or rectal cancer liver spread
This trial studies whether a liver transplant can help people with colon or rectal cancer that has spread to the liver (but not elsewhere). It aims to improve outcomes by removing the diseased liver when the cancer has responded to chemotherapy and can still be controlled.
OsloAges 18 years+ - 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+ - NCT06234007RecruitingPhase 2
Short radiation plus combo therapy for advanced rectal cancer
This trial tests a short course of radiation therapy followed by a combination of three drugs (fruquintinib, adebrelimab, and CAPOX chemotherapy) before surgery for people with locally advanced rectal cancer. The goal is to see if this approach can shrink the tumor and improve outcomes.
WuhanAges 18–75 - NCT05883800Recruiting
Total treatment with tailored radiation for advanced rectal cancer
This study tests a “total neoadjuvant” approach—chemotherapy first, then radiation—using adaptive (tailored) radiation planning for people with locally advanced rectal cancer. It may help improve tumor control while adjusting the radiation based on how your cancer and anatomy respond.
BergenAges 18 years+ - NCT06331988Recruiting
Study of colon cancer, bacteria, and the immune system
This study looks at how bacteria in your gut, your immune system, and colon cancer interact. It aims to understand these connections to improve future treatments.
MilanAges 18–75 - NCT03465982Recruiting
Timing surgery after chemotherapy and radiation for rectal cancer
This trial studies the best time to do surgery after you finish chemotherapy and radiation for rectal cancer. It may help improve how well minimally invasive surgery works and how safely it can be done.
Alessandria, ALAges 18 years+ - 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.
Montreal, QuebecAges 18 years+ - NCT05228431RecruitingPhase 2
Tested treatment plan for locally advanced rectal cancer
This Phase 2 study looks at a modified “sandwich” treatment sequence for people with locally advanced rectal cancer—aiming to control the cancer before and after surgery. It may help you if you’re eligible and can follow the study’s treatment and safety requirements.
Guangzhou, GuangdongAges 18–75 - NCT05927584Recruiting
Local removal for early rectal cancer without extra treatment
This trial studies removing an early rectal cancer tumor locally (through the rectum/anal area) with no additional therapy afterward. The goal is to preserve organs and maintain quality of life while still trying to cure the cancer.
MadridAges 18 years+ - NCT07849023Recruiting
Precise sphincter-saving surgery for early rectal cancer
This trial tests a refined surgical method for removing rectal tumors while preserving the anal sphincter, which may help avoid a permanent colostomy. It is for patients with early-stage rectal cancer that is close to the anus and has not spread.
Wenzhou, ZhejiangAges 18–75 - NCT06455124RecruitingPhase 2
Short radiation and chemo-immunotherapy for early rectal cancer after local surgery
This trial tests a combination of short-course radiation, chemotherapy (CapeOx), and an immunotherapy drug (PD-1 inhibitor) for people with early-stage rectal cancer who have had a local excision but are at high risk of the cancer coming back. The goal is to avoid more extensive surgery while still effectively treating the cancer.
ShanghaiAges 18–75 - 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+ - NCT06462053RecruitingPhase 2
Short radiotherapy plus chemo and immunotherapy for early low rectal cancer
This study is testing whether a short course of radiation combined with chemotherapy and an immunotherapy drug works better than the standard longer radiation and chemotherapy for early-stage rectal cancer that is low in the rectum. The goal is to see if this shorter treatment can help patients avoid surgery or have a better outcome.
ShanghaiAges 18–75 - NCT06314646Recruiting
Comparing two ways to reconnect the intestine after rectal cancer surgery
This study compares two ways of reconnecting the intestine after rectal cancer surgery. It looks at a newer method called TTSS against the standard double-stapled technique.
Rozzano, MIAges 18 years+ - NCT07809893RecruitingPhase 2
New drug combo for advanced colorectal cancer with BRAF mutation
This trial tests a new combination of drugs for people with advanced colorectal cancer that has a specific genetic change called BRAF V600E. The treatment includes a targeted therapy (ivosidenib) plus chemotherapy and a pain-relief drug (celecoxib). It is for people whose cancer has stopped responding to previous treatments, including BRAF-targeted therapies.
Guangzhou, GuangdongAges 18–70 - NCT06525428RecruitingPhase 2
Adding radiation and immunotherapy to standard care for advanced colorectal cancer
This trial is testing a combination of standard chemotherapy, radiation therapy, and an immunotherapy drug (toripalimab) for people with metastatic colorectal cancer. It aims to see if adding radiation therapy and immunotherapy can help shrink tumors and improve outcomes.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06341296RecruitingPhase 2
Irinotecan liposomes for first-line advanced colorectal cancer
This trial tests a new type of chemotherapy (irinotecan liposomes) as a first treatment for metastatic colorectal cancer that has not been treated before. It focuses on patients with specific genetic changes (RAS or BRAF V600E mutation) or right-sided colon cancer, and looks at how well the drug works.
Sichuan, Sichuan, ChengduAges 18–85 - NCT06547203RecruitingPhase 2
Cetuximab, irinotecan, and toripalimab for right-sided colorectal cancer
This trial tests a combination of three drugs (cetuximab, irinotecan, and toripalimab) for people with advanced right-sided colon cancer that does not have certain gene mutations. It's for those whose cancer has gotten worse after standard treatments.
Guangzhou, GuangdongAges 18–80 - NCT05215535Recruiting
Liver MRI before rectal cancer treatment
This trial tests whether doing an MRI scan of the liver before rectal cancer treatment helps doctors plan care better. You may be asked to have MRI before starting treatment and follow the study plan.
GothenburgAges 18 years+ - NCT06566755RecruitingPhase 3
New drug combo for a common type of colorectal cancer
This trial tests a combination of a new immunotherapy (cadonilimab) with standard chemotherapy (capecitabine, oxaliplatin) and bevacizumab for people with metastatic colorectal cancer that has a RAS mutation or is located on the right side of the colon. The goal is to see if this combination works better than the current standard of care as a first treatment.
Shenyang, LiaoningAges 18–75 - NCT07750158RecruitingPhase 3
Zanzalintinib for colorectal cancer with residual tumor dna
This trial is testing a new drug (zanzalintinib) alone or with pembrolizumab to see if it can stop cancer from coming back in people with colorectal cancer who have no visible cancer on scans but still have tumor DNA in their blood.
Council Bluffs, IowaAges 18 years+ - NCT05964530Recruiting
Testing local removal versus radical surgery for rectal cancer
This trial looks at whether removing the rectal tumor locally (through the anus) can work as well as a more extensive operation after scans show no remaining cancer. It may help some people avoid bigger surgery if the cancer truly appears gone after treatment.
TaipeiAges 18–75 - NCT05250648RecruitingPhase 4
HIPEC with mitomycin C after surgery for colon cancer in the belly
This study looks at adding a heated medicine treatment (HIPEC with mitomycin C) during surgery to treat colon cancer that has spread to the lining of the abdomen (peritoneum). It aims to improve outcomes after surgeons remove visible tumor completely.
Elche, AlicanteAges 18 years+ - NCT06184698RecruitingPhase 2
