Personalized help for bowel symptoms after rectal cancer treatment
This trial studies how to improve bowel symptoms in people treated for rectal cancer. It tests personalized care plans and looks at different factors that may contribute to bowel problems after surgery or a watch-and-wait approach.
Leuven, Vlaams-BrabantAges 18 years+ - NCT06885385RecruitingPhase 2
Study of JS207 with or without JS015 and chemo for colorectal cancer
This trial tests a new drug combination (JS207 with or without JS015) along with chemotherapy for people with advanced colorectal cancer that has not spread to other parts of the body. It aims to see if the treatment is safe and helps shrink tumors.
Beijing, Beijing MunicipalityAges 18–75 - NCT06903858RecruitingPhase 2
Toripalimab plus celecoxib for dMMR/MSI-H colorectal cancer
This trial tests whether combining toripalimab (an immunotherapy) with celecoxib (an anti-inflammatory drug) can shrink locally advanced colorectal tumors that have specific genetic features (dMMR or MSI-H). It aims to help people who haven't had any prior treatment for their colorectal cancer.
Guangzhou, GuangdongAges 18 years+ - NCT06880055Recruiting
Shield blood test for colorectal cancer screening
This study is testing the Shield blood test for people at average risk of colorectal cancer. It looks at how well the test works for screening, so you can learn about your risk with a simple blood draw.
Chandler, ArizonaAges 45–81 - NCT06883084Enrolling by invitation
How lymph node changes affect rectal cancer outcomes
This trial looks at how much the lymph nodes respond to chemoradiation before surgery in people with locally advanced rectal cancer. It aims to understand if that response can predict long-term results and guide future treatment choices.
Ages 18–65 - 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.
