  • Publication number: 20180057592
    Abstract: Provided are monoclonal antibodies and antigen-binding fragments thereof that bind to CD47 of multiple mammalian species, block the binding of SIRPalpha and TSP1 to CD47, promote phagocytosis of susceptible cancer cells, and reverse TSP1 inhibition of nitric oxide signaling, as well as monoclonal antibodies and antigen binding fragments thereof that compete with the former for binding to CD47 and that exhibit similar biological activities. Also provided are combinations of any of the foregoing. Such antibody compounds are variously effective in 1) treating tissue ischemia and ischemia-reperfusion injury (IRI) in the setting of organ preservation and transplantation, pulmonary hypertension, sickle cell disease, myocardial infarction, stroke, and other instances of surgery and/or trauma in which IRI is a component of pathogenesis; 2) in treating autoimmune and inflammatory diseases; and 3) as anti-cancer agents for treating susceptible cancer cells, promoting their phagocytic uptake and clearance.
