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.

The present disclosure relates to protein molecules that specifically bind to 5T4 and/or 4-1BB. The molecules may have at least one humanized 5T4-binding or 4-1BB-binding domain. Such molecules are useful for the treatment of cancer. The protein molecule binding to 5T4 or 4-1BB may have a second binding domain that binds to another target. The molecules may bind both 5T4-expressing cells and a cell-surface molecule expressed by an effector cell to enhance effector cell activation, proliferation, survival and/or effector-cell mediated cytotoxicity. The disclosure also provides pharmaceutical compositions comprising the 5T4-binding or 4-1BB-binding polypeptide or protein molecules, nucleic acid molecules encoding these polypeptides and methods of making and using these molecules.
