Comment: Ontorpacept (TTI-621) is a 345 amino acid fusion protein that consists of the N-terminal V domain of human SIRPα fused to the Fc region of human IgG1 that was designed as an immuno-oncology agent [1]. The SIRPα domain binds to CD47 on cancer cells (to block the CD47-SIRPα anti-phagocytic signal). Inclusion of the IgG1 Fc region enhances phagocytosis of malignant cells via interaction with Fcγ receptors.
