What is CDX-1140?

CDX-1140 is a fully human IgG2 agonistic monoclonal antibody that binds CD40, a tumor necrosis factor receptor superfamily member expressed on dendritic cells, macrophages, B-cells and a range of tumor cells. It activates CD40-dependent signaling, promoting antigen-presenting cell activation and T-cell activation. It is being studied in ovarian, fallopian tube and peritoneal carcinomas.
