Recruiting studies
- NCT05201430RecruitingPhase 3
FOLFOXIRI vs CapeOX before surgery for locally advanced rectal cancer
This trial compares two chemotherapy plans given before rectal cancer surgery to see which helps more people and works better for disease control. If you have locally advanced rectal cancer and have not had treatment yet, this study may be an option.
Shanghai, Shanghai MunicipalityAges 18–75 - 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+ - 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 - 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+ - NCT05299840Recruiting
Test a device to choose the first chemo for metastatic colon cancer
This study tests whether using the Oncogramme® device to guide the first-line treatment improves care for people with metastatic colorectal (colon/rectum) cancer. If the device helps pick the most suitable standard chemotherapy plan, it could lead to better outcomes than choosing without it.
MarseilleAges 18 years+ - NCT05379595RecruitingPhase 1/Phase 2
Amivantamab for advanced colon or rectal cancer with specific tumor traits
This Phase 1/2 study tests amivantamab alone or combined with standard chemotherapy to treat advanced or metastatic colon or rectal cancer. You may be able to join if your tumor has the right genetic profile (typically “wild-type” for certain genes and no HER2 amplification) and your cancer has measurable or biopsy-able lesions.
Birmingham, AlabamaAges 18 years+ - NCT05450029RecruitingPhase 2
Adding immunotherapy to chemo-radiation for rectal cancer
This Phase 2 trial studies whether adding sintilimab (an immunotherapy drug) to standard chemo-radiation before surgery can improve outcomes for people with locally advanced rectal cancer. It’s aimed at tumors with certain immune “signature” scores and specific cancer stage features.
Guangzhou, GuangdongAges 18–75 - NCT05523245Recruiting
AI MRI test to predict treatment response in rectal cancer
This study uses an AI computer program to read special MRI images and predict how well treatment (given before surgery) will work for people with locally advanced rectal cancer. It may help doctors better plan who benefits most from neoadjuvant therapy (treatment before surgery).
Guangzhou, GuangdongAges 18 years+ - NCT05571644RecruitingPhase 2
Study compares two pre-surgery treatments for locally advanced rectal cancer
This Phase 2 trial tests whether a newer combination chemotherapy plus an immunotherapy medicine (cadonilimab/AK104) works better than standard chemotherapy before surgery for locally advanced colorectal cancer. The goal is to shrink the tumor and improve how well treatment works after surgery.
Guangzhou, GuangdongAges 18–70 - NCT05576480RecruitingPhase 2
Immunotherapy plus chemotherapy before surgery for rectal cancer without mismatch repair
This Phase 2 study tests penpulimab (an immunotherapy medicine) given with CAPEOX chemotherapy before surgery for rectal cancer that is “MSS” (not the mismatch-repair type). It aims to shrink the tumor and improve outcomes by treating before the operation.
Shanghai, None SelectedAges 18–75 - NCT05579353Recruiting
Study stool and blood markers in colorectal cancer treatment planning
This study looks at special tiny cell-signal particles (called exosomes) and related pathways to understand colorectal cancer. Your results from samples may help researchers learn how these signals relate to the disease after surgery.
Jinan, LixiaAges 18–80 - NCT05628038RecruitingPhase 2
Radiation plus immunotherapy for recurrent rectal cancer
This Phase 2 trial tests whether giving targeted radiation and an immunotherapy drug together can control locally recurring rectal cancer in the pelvis. It may help shrink tumors and slow disease growth, especially after certain prior treatments.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05692024RecruitingPhase 1/Phase 2
Coffee and gut bacteria study after colon or rectal cancer
This early-phase study tests whether a coffee-related approach can change gut bacteria and blood “metabolites” after treatment for stage I–III colon or rectal cancer. The goal is to learn if these changes could help improve health after standard cancer treatment.
Boston, MassachusettsAges 18 years+ - NCT05725200RecruitingPhase 2
Personalized treatment plan for metastatic colon or rectal cancer
This Phase 2 trial tests an individualized treatment chosen from your tumor’s lab testing (genetic and RNA profile plus a drug-sensitivity test from your tumor cells). It may help by matching you to targeted anti-cancer drugs that are most likely to work for your specific cancer.
OsloAges 18 years+ - NCT05877573Recruiting
Toripalimab with chemo-radiation before surgery for rectal cancer
This trial studies whether adding toripalimab (an immunotherapy drug) to standard chemo-radiation before surgery can improve outcomes for people with higher-risk, locally advanced rectal cancer. It is meant for cancers that are mismatch-repair “MSS/pMMR,” and it checks safety plus effectiveness as a first treatment.
Guangzhou, GuangdongAges 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+ - NCT05914766Recruiting
Support program for newly diagnosed rectal cancer patients
This trial tests an informational and supportive care program for people with newly diagnosed, locally advanced rectal cancer. It may help by providing education and practical support around next steps in treatment.
Boston, MassachusettsAges 18 years+ - NCT05916040Recruiting
MRI-guided treatment for locally advanced rectal cancer
This trial studies a total “before-surgery” treatment plan for locally advanced rectal cancer, using MRI (a detailed scan) to help guide radiation. It may help patients by aiming to shrink the tumor and improve the chance of successful surgery.
Jette, Brussels CapitalAges 18 years+ - 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+ - NCT05939661RecruitingPhase 2
Total treatment before surgery for early rectal cancer
This Phase 2 study tests a “total neoadjuvant” approach, meaning you receive cancer treatment before surgery, to improve safety and effectiveness for rectal cancer. It may help by shrinking the tumor and planning a more effective operation, while researchers carefully track side effects.
OsakaAges 18 years+ - NCT05943210Recruiting
Molecular testing of rectal cancer after short-course radiation
This study looks at molecular (tumor biology) features of rectal cancer in people receiving standard short-course radiation. Your tissue and/or samples may be used to better understand the cancer and how it responds to treatment.
Chicago, IllinoisAges 18–90 - NCT05957016RecruitingPhase 2
New treatment before and during rectal radiation with chemo
This Phase 2 study tests a treatment plan given before surgery (neoadjuvant) along with radiation and chemotherapy (concurrent chemoradiotherapy) for locally advanced rectal cancer. It may help shrink the cancer before the next steps of care and improve control of the disease.
Chongqing, Chongqing MunicipalityAges 18–75 - 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 - NCT05965531RecruitingPhase 2
TAS-102 plus radiation before surgery for rectal cancer
This trial studies whether adding TAS-102 (a chemotherapy medicine) to radiation given before treatment improves outcomes for certain locally advanced rectal cancers. It may help by trying to shrink the tumor before the next steps of care.
