  • Publication number: 20240043522
    Abstract: The present invention provides molecules comprising a modified Fc region which do not mediate antibody effector functions such as antibody-dependent cellular cytotoxicity (ADCC) but maintain a long serum half-life due to binding to the neonetal Fc receptor (FcRn). To this end, the molecules of the present invention do not comprise the disulfide bridges of the antibody hinge region but are linked C-terminally by at least two covalent bonds. Furthermore, the molecules of the present invention comprise CH2 domains with an additional disulfide bond.
