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 - NCT07150949RecruitingPhase 2
Comparing two radiation schedules with chemotherapy and immunotherapy for rectal cancer
This study tests two different radiation regimens (long-course vs. short-course) combined with chemotherapy (CAPOX), an immunotherapy drug (PD-1 antibody), and a COX-2 inhibitor for people with MSS locally advanced rectal cancer. The goal is to see which approach works better in shrinking the tumor before surgery.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07446322RecruitingPhase 2
Study of a new drug plus standard chemo for advanced colorectal cancer
This trial tests if adding the experimental drug pelareorep to standard chemotherapy (FOLFIRI) and bevacizumab can help people with a specific type of advanced colorectal cancer that has a RAS mutation and is not caused by high microsatellite instability. You may be able to join if you've already tried one type of chemotherapy and it stopped working or you couldn't tolerate it.
Homewood, AlabamaAges 18 years+ - NCT06549907Recruiting
Study of double immunotherapy plus anti-angiogenic therapy
This trial studies people with certain types of colorectal or other solid tumors that did not respond to a single immunotherapy drug. It tests whether adding a second immune checkpoint blocker and an anti-angiogenic drug can help control the cancer.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06455254RecruitingPhase 2
Cadonilimab plus regorafenib for advanced colorectal cancer
This trial tests a combination of two drugs (cadonilimab plus regorafenib) as a possible third-line option for people with colorectal cancer that has spread to the liver. It is for patients whose cancer is the MSS/pMMR type and who have already tried standard treatments without success.
Suzhou, JiangsuAges 18–75 - NCT06321081RecruitingPhase 2
Rechallenge combo for metastatic colorectal cancer
This trial tests a combination of three drugs (cetuximab, irinotecan, and envafolimab) as a ‘rechallenge’ – meaning if you had good results with cetuximab or irinotecan before, trying them again with a new drug might help shrink or control your cancer.
