  • Patent number: 11674959
    Abstract: The present invention in various aspects and embodiments involves pharmaceutical compositions prepared by contacting a candidate ?- or ?-integrin-binding molecule, or panel thereof, with an integrin heterodimer, and quantifying heterodimer disruption by the candidate molecule. An integrin-binding molecule, or derivative thereof, that disrupts the integrin heterodimer is selected and is formulated into a pharmaceutical composition for administration to a subject, e.g., who has a disease or disorder related to abnormal vascularization.
