Proposed Mechanism of Action
CC-90002 is an anti-CD47 antibody. CD47 interacts with signal regulatory protein-α (SIRPα) on macrophages to inhibit cell phagocytosis. It plays an important role in the ability of the immune system to detect nonself from self.1-4 Loss of CD47 expression results in the cell being recognized as foreign for phagocytosis.2,5
MAb, monoclonal antibody; SIRPα, signal-regulatory protein α.

For growth and metastasis, solid tumors must avoid phagocytosis by tumor-associated macrophages.5,6 Evidence has demonstrated that CD47 is upregulated in various solid tumors as well as hematologic malignancies, and may protect these cells from phagocytosis.5,6 A preclinical study showed that inhibiting the interaction between CD47 and SIRPα inhibited the growth of solid tumor cells in vitro and in mouse models.6
