Test vitamin E plus two cancer drugs for metastatic colon cancer
This trial tests whether adding vitamin E to two cancer medicines (fruityquintinib and tislelizumab) can work better in people with metastatic colorectal cancer that is mismatch-repair stable (MSS). It may help if your cancer has grown despite standard treatment, and you can meet the study’s safety and blood/organ requirements.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05898789Recruiting
Virtual rehab program for cancer survivors
This trial tests a virtual (online) rehabilitation and exercise program for people after breast, colorectal, head and neck, or certain blood cancers. It may help improve recovery and daily functioning by supporting safe activity and targeted rehab after treatment.
Toronto, OntarioAges 18 years+ - NCT05930496Recruiting
Exercise after colorectal cancer to change gut bacteria
This study tests whether a structured exercise program can improve the makeup of gut microbiota (gut bacteria) in people who have finished treatment for stage II–III colorectal cancer. It may help learn how exercise supports recovery, and it involves remote or in-person sessions with gut-focused tracking.
Seattle, WashingtonAges 18–70 - NCT05950503Recruiting
MRI to assess liver spread from colon cancer
This trial studies how well MRI can evaluate liver metastases (spread to the liver) from colorectal cancer. If you have measurable liver lesions, your MRI results may help doctors better track and plan care.
RomaAges 18–85 - NCT05993923Recruiting
Geriatric team support for seniors having colorectal cancer surgery
This study tests whether a team of specialists (including a geriatric doctor) can help people aged 70+ recover better after colorectal cancer surgery. The goal is to see if this approach improves your daily functioning and independence after the operation.
