  • Patent number: 11939392
    Abstract: The present disclosure relates to protein molecules that specifically bind to CD123, which may have at least one humanized or human CD123-binding domain. Such molecules are useful for the treatment of cancer. The protein molecule binding to CD123 may have a second binding domain that binds to another target. In one embodiment, multi-specific polypeptide molecules bind both CD123-expressing cells and the T-cell receptor complex on T-cells to induce target-dependent T-cell cytotoxicity, activation, and proliferation. The disclosure also provides pharmaceutical compositions comprising the CD123-binding polypeptide molecules, nucleic acid molecules encoding these polypeptides and methods of making these molecules.
