  • Patent number: 11111305
    Abstract: This invention describes the design of bispecific antibodies that function as conditionally effective therapeutics by binding to a functionally silent epitope on one component of a targeted signaling complex and simultaneously binding to a second protein, whose expression or accessibility is cell- or disease environment-specific, and whose antibody-driven proximity to the signaling complex leads to an alteration of signal transduction.
