Scottsdale, ArizonaAges 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+ - NCT05248581Recruiting
Living donor liver transplant for unresectable colon cancer spread
This trial looks at using a living donor liver transplant for people whose colon or rectal cancer has spread to the liver in a way that can’t be removed with standard surgery. It may help if you might otherwise have limited options because your liver surgery would be too risky.
Rochester, New YorkAges 18 years+ - 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+ - NCT04927897Recruiting
Testing where to aim extra rectal radiation before surgery
This trial tests the best place to target an “extra boost” of radiation inside the rectum for certain rectal cancer patients. It may help guide more precise treatment planning before they have total mesorectal excision (TME) surgery.
Maastricht, LimburgAges 18 years+ - NCT04190589Recruiting
Robotic right-sided colon surgery for early to mid-stage cancer
This study looks at a newer, robot-assisted surgical approach to remove part of the right colon completely when colon cancer is suspected or confirmed. It may help by aiming for more complete tumor removal while tracking safety and outcomes.
VejleAges 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 - NCT04808323RecruitingPhase 1
MRI-guided radiation to help preserve organs in rectal cancer
This Phase 1 study tests a radiation treatment approach guided by MRI scans to help keep nearby organs functioning while treating rectal cancer. It is designed to find a safe, effective way to target the tumor and adjust treatment during the course of therapy.
Milwaukee, WisconsinAges 18 years+ - NCT04749108RecruitingPhase 2/Phase 3
Tailored treatment for locally advanced rectal cancer after FOLFIRINOX
This trial studies a more customized treatment plan for people with locally advanced rectal (bowel) cancer after they receive FOLFIRINOX chemotherapy. It aims to reduce tumor spread risk and improve outcomes by tailoring the next steps based on scan details and your health status.
Marseille, Bouches Du RhôneAges 18 years+ - NCT04184973Recruiting
Testing a colon bypass device during colorectal cancer surgery
This trial studies a device (CG-100) placed inside the bowel to see if it can improve safety and outcomes during surgery for colorectal cancer. You would be asked to follow extra study check-ins after your operation, and the team would monitor whether the device works as intended.
Irvine, CaliforniaAges 22–70 - NCT04035642Recruiting
Single high-dose MRI-guided radiation for intermediate prostate cancer
This trial tests whether a single, image-guided radiation treatment can treat intermediate-risk prostate cancer while better protecting the urethra (the urine tube). It may help patients get effective cancer control with potentially fewer urinary side effects, depending on the results.
LisbonAges 18 years+ - NCT03837782Enrolling by invitation
Surgery outcomes for early to mid-stage colon cancer
This study looks at how well surgery works for people with colorectal cancer that has not spread to distant organs. It mainly includes patients who can have the tumor completely removed and accurately staged using lymph node samples.
Tianjin, Tianjin MunicipalityAges 18–90 - NCT03179540Recruiting
Watch-and-wait treatment after rectal cancer radiation
This trial looks at a “non-surgery” approach for some people with locally advanced rectal cancer who respond very well to radiation plus chemotherapy. If your cancer shows a complete clinical response on follow-up checks, the study may help you avoid an immediate major operation while closely monitoring you.
Toronto, OntarioAges 18 years+ - NCT03692429RecruitingPhase 1
Testing new immune cells plus chemo for advanced colon cancer
This Phase 1 study tests CYAD-101, an immune-cell treatment made from donor T-cells, given with standard chemotherapy. It is for people with colon or rectal cancer that has spread and has not responded to prior treatments.
Tampa, FloridaAges 18 years+ - NCT05049317Recruiting
Check urinary and sexual function after rectal cancer surgery
This study looks at how a specific rectal surgery (laparoscopic total mesorectum excision) affects urinary and sexual function after the operation. It may help patients by tracking what to expect and which factors relate to better recovery.
Wuhan, HubeiAges 18–70 - NCT05768503RecruitingPhase 3
Test new drugs after colorectal cancer chemotherapy
This Phase 3 trial compares a new treatment combination (chidamide plus sintilimab plus bevacizumab) versus the standard second-line chemotherapy (FOLFIRI plus bevacizumab) for advanced colorectal cancer that is microsatellite stable/low. It aims to see which treatment works better and is safer for people whose cancer grew after first-line oxaliplatin-based therapy.
Hefei, AnhuiAges 18–75 - NCT04087421RecruitingPhase 3
Transanal irrigation vs glycerol suppositories for LARS
This trial compares two ways to help bowel control in people with low anterior resection syndrome (LARS) after low rectal surgery. It aims to see which option works better when standard treatments have not helped enough.
AarhusAges 18 years+ - NCT02215889RecruitingPhase 1/Phase 2
Partial liver transplant for colon or rectal cancer spread to liver
This trial tests whether transplanting part of the liver can help people with colon or rectal cancer that has spread to the liver but cannot be removed with surgery. It also aims to make sure the cancer is limited mainly to the liver and that you are healthy enough for major treatment.
OsloAges 18 years+ - NCT05495048Recruiting
Transvaginal surgery vs standard laparoscopy for right colon removal
This study compares two surgical approaches for removing the right side of the colon in certain women with colon cancer or a high-risk pre-cancer. It aims to see whether the less invasive transvaginal approach can be done safely and work as well as standard laparoscopic surgery.
ShanghaiAges 18–75 - NCT06402188Recruiting
ColoSeal Device Study for Rectal Cancer Surgery
This study tests a new device called the ColoSeal ICD System that may help protect the reconnection of your bowel after surgery for rectosigmoid or rectal cancer. It is designed for people who are already scheduled for surgery that includes a temporary colostomy or ileostomy.
YerevanAges 18–70 - NCT07786818Recruiting
Colorectal cancer screening marker study
This study looks for markers in stool and saliva that might indicate the presence of precancerous growths in the colon. If you are scheduled for a colonoscopy, you may be able to participate by providing samples beforehand.
Bothell, WashingtonAges 18 years+ - NCT07732894Recruiting
Exercise and Guided Imagery for Bowel Symptoms After Cancer Surgery
