GtoPdb Ligand ID: 12652

Synonyms: Hu5F9-G4
Immunopharmacology Ligand
Compound class: Antibody
Comment: Magrolimab (Hu5F9-G4) is a clinical lead, humanized monoclonal antibody, that binds to and blocks the function of cluster of differentiation 47 (CD47), a 'don't-eat-me' signal that is overexpressed by some cancer cells [1]. CD47-blockade disrupts the CD47-SIRPα anti-phagocytic checkpoint, which induces an immunostimulating effect that promotes macrophage-mediated phagocytosis of tumour cells [2].

Immunopharmacology Comments
Magrolimab (Hu5F9-G4) blocks the CD47-SIRPα anti-phagocytic checkpoint. In cancer cells that overexpress CD47, this mechanism promotes an immunostimulating effect that induces macrophage-mediated phagocytosis of the tumour cells.
