Official title
A Phase I/II Trial of Botensilimab, Balstilimab and Regorafenib (BBR) in Patients With Microsatellite Stable (MSS) Metastatic Colorectal Cancer Who Progressed on Prior Chemotherapy
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase I/II trial tests how well botensilimab, balstilimab, and regorafenib works in treating patients with microsatellite stable colorectal cancer that has spread from where it first started (primary site) to other places in the body (metastatic) or that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and who have progressed on prior chemotherapy. Immunotherapy with monoclonal antibodies, such as botensilimab and balstilimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Regorafenib binds to and inhibits growth factor receptors, which may inhibit the growth of new blood vessels that tumors need to grow. Giving botensilimab, balstilimab, and regorafenib in combination may work better in treating patients with metastatic colorectal cancer than giving these drugs alone.
