Description
Magrolimab (Hu5F9-G4) is a monoclonal antibody immunotherapy that targets the CD47 protein on cancer cells. In colorectal cancer treatment, it is being combined with established regimens including FOLFIRI/bevacizumab for previously treated metastatic disease and with cetuximab for advanced cases. This anti-CD47 antibody works to enhance immune system recognition and destruction of cancer cells by blocking the "don't eat me" signal that tumors use to evade immune surveillance.
Mechanism of Action
Magrolimab binds to CD47, a transmembrane protein overexpressed on many cancer cells that serves as a "don't eat me" signal to macrophages. By blocking CD47, magrolimab enables macrophages to recognize and phagocytose cancer cells, while also promoting adaptive immune responses through enhanced antigen presentation. This mechanism complements other therapies by removing a key immune evasion strategy used by colorectal tumors.
