Ontorpacept
Based on 1 publication(s) in Google Scholar
Ontorpacept (TTI-621) is a soluble fusion protein that consists of the human SIRPα N-terminal (1-118) linked to the Fc region of human IgG1. The N-terminal (1-118)-fragment of ontorpacept is a binding domain for CD47 which is an inhibitor of phagocytosis by macrophages. Ontorpacept is a CD47-blocking checkpoint inhibitor with antitumor activity.
