Provided herein are methods of use and treatment using a first or a first and second monovalent antigen-binding constructs targeting HER2. The monovalent antigen-binding constructs can include at least one antigen-binding polypeptide comprising a heavy chain variable domain, wherein the antigen-bind polypeptide specifically binds HER2; and a heterodimeric Fc, the Fc comprising at least two CH3 sequences, wherein the Fc is coupled, with or without a linker, to the antigen-binding polypeptide. |
