Recruiting studies
- NCT06928584RecruitingPhase 2
Shorter Radiation Plus Immunotherapy for Recurrent Rectal Cancer
This trial tests whether a shorter, higher-dose radiation course (hypofractionated) combined with immunotherapy works better than standard radiation for locally recurrent rectal cancer that hasn't spread elsewhere. It's for people who haven't had chemotherapy or recent pelvic radiation.
Shanghai, Shanghai MunicipalityAges 18–75 - 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 - NCT06281405RecruitingPhase 2
CAPOX and immunotherapy with or without radiation for rectal cancer
This trial tests whether adding radiation therapy to a combination of chemotherapy (CAPOX) and an immunotherapy drug (PD-1 antibody) is more effective than the combination alone for people with locally advanced rectal cancer that is MSS (microsatellite stable) or pMMR. It aims to improve outcomes for patients with high-risk features.
ShanghaiAges 18–70 - NCT06282445RecruitingPhase 2
Combination therapy for first-line metastatic colorectal cancer
This trial tests whether adding the immunotherapy drug adebrelimab to standard chemotherapy plus bevacizumab can help people with a specific type of metastatic colorectal cancer that cannot be removed by surgery. It is for patients whose tumors are microsatellite stable (MSS) or have normal mismatch repair (pMMR).
Jinhua, ZhejiangAges 18–75 - NCT05963490RecruitingPhase 2
Regorafenib with or without targeted immunotherapy and radiation for spread colon cancer
This Phase 2 study tests whether taking regorafenib alone or with immunotherapy (toripalimab) and a lower-dose radiation plan can better control metastatic colon or rectal cancer that has MSS/pMMR. It may help by combining cancer-blocking medicine with immune activation and focused radiation to metastatic spots.
ShanghaiAges 18–70 - NCT05972655RecruitingPhase 2
Testing shorter rectal radiation with chemotherapy plus immunotherapy
This Phase 2 study tests whether a shorter course of radiation, combined with chemotherapy (CAPOX) and an immunotherapy drug (tislelizumab), can control middle and low rectal cancer. It may also help people who strongly want to keep their anus, if the cancer and overall health fit the study rules.
Hanzhou, ZhejiangAges 18–75 - NCT05378919RecruitingPhase 2
Testing new pre-surgery treatment for locally advanced rectal cancer
This Phase 2 trial compares a pre-surgery (neoadjuvant) treatment plan versus the standard plan for people with stage II–III rectal cancer. The goal is to see which approach works better and is safe before surgery.
KaunasAges 18 years+ - NCT05555888RecruitingPhase 2
Immunotherapy plus short-course radiation for early rectal cancer
This study tests whether combining immunotherapy with a short course of radiation given before surgery can improve outcomes in early-stage rectal cancer. It may help the immune system work better against the tumor before it is removed.

It’s mainly for people who have not had prior rectal cancer treatment and who fit several health and cancer-spread requirements.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05245474RecruitingPhase 2
Before-surgery chemoradiation plus PD-1 for locally advanced rectal cancer
This trial studies giving long-course radiation and chemotherapy before surgery, plus an immunotherapy medicine (PD-1) to help the tumor shrink more. It’s for people with stage II or III rectal cancer that has not spread to distant organs.
Beijing, Beijing MunicipalityAges 18–75 - NCT04991948RecruitingPhase 1
Testing pembrolizumab after CYAD-101 plus FOLFOX in colon cancer
This early-phase study tests whether adding pembrolizumab after CYAD-101 and FOLFOX chemotherapy can help treat metastatic colon or rectal cancer. It is mainly looking for safety and signs of how well the treatment works in people whose cancer has not responded to prior therapy.
Jacksonville, FloridaAges 18 years+ - NCT04938986Recruiting
Testing a tumor marker to predict colon cancer relapse risk
This study looks at whether a lab test on your tumor can better predict the chance that non-metastatic colon cancer will come back after surgery. Researchers will compare relapse risk using the Immunoscore® test to help guide follow-up and treatment decisions.
MarseilleAges 18–80 - NCT05412082RecruitingPhase 1
Smart chemo and radiation plan for locally advanced rectal cancer
This Phase 1 study tests a “smart” total treatment plan using chemotherapy (chemo) and radiation before surgery for people with locally advanced rectal cancer. The goal is to see if this approach is safe and can work well while helping plan treatment based on your situation.
Miami, FloridaAges 18 years+ - NCT06767007RecruitingPhase 2
Radiation plus immunotherapy for recurrent rectal cancer
This trial studies a combination of SBRT (a precise kind of radiation) and an immunotherapy drug (PD-1 antibody) for people whose rectal cancer has come back in the pelvis and cannot be removed by surgery. The goal is to see if this treatment can shrink the tumor or stop it from growing.
Guangzhou, GuangdongAges 18–75 - NCT07454720RecruitingPhase 2/Phase 3
Study of Adebrelimab with SHR-8068 and chemoradiation before surgery for rectal cancer
This trial tests whether adding two immunotherapy drugs (adebrelimab and SHR-8068) to standard chemoradiation before surgery can improve outcomes for adults with locally advanced rectal cancer that can be surgically removed.
Wuhan, HubeiAges 18–75 - NCT06864013RecruitingPhase 2
Short course radiation with chemo and immunotherapy for rectal cancer
This trial tests a combination of short course radiation therapy, chemotherapy, and two immunotherapy drugs for people with a specific type of rectal cancer that is locally advanced but can still be removed by surgery. It may offer a more effective treatment option for those with mismatch repair proficient (pMMR) or microsatellite stable (MSS) tumors.
Hangzhou, ZhejiangAges 18–75 - NCT07696793RecruitingPhase 4
Simethicone colonoscopy prep for cancer screening
This trial tests a colonoscopy preparation drink that contains simethicone (a gas-relief ingredient) to see if it works better than standard prep for people who are already scheduled for a screening colonoscopy after a positive stool test. It may help make the procedure more comfortable and effective.
