The present disclosure relates to dimers of engineered polypeptides having a binding affinity for the neonatal Fc receptor FcRn, and provides an FcRn binding dimer, comprising a first monomer unit, a second monomer unit and an amino acid linker, wherein said first and second monomer unitseach comprisesan FcRn binding motif. Said FcRn binding dimerbinds FcRn with higher capacity compared to said first monomer unitor second monomer unit alone.The present disclosure also relates to the use of said FcRn binding dimeras an agent for modifying pharmacokinetic and pharmacodynamic properties and as a therapeutic agent. |
