  • Publication number: 20260092123
    Abstract: The present disclosure relates to engineered IgG molecules having an IgM C?2 domain substituted for all or a portion of an IgG hinge region. Engineered IgG molecules may include one or more targeting moieties that are capable of agonizing a cell surface receptor and may be used, for example, in methods of agonizing certain receptors.

  • Publication number: 20260085116
    Abstract: The invention provides antibody heavy chain constant regions with a hinge region modified to reduce binding to Fc? receptors. The modification occurs within positions 233-236 by replacement of natural residues by glycine(s) and/or deletion(s). Such modifications can reduce binding of an antibody bearing such a constant region to Fc? receptors to background levels. The constant regions can be incorporated into any format of antibody or Fc fusion protein. Such antibodies or fusion proteins can be used in methods of treatment, particularly those in which the mechanisms of action of the antibody or Fc fusion protein is not primarily or at all dependent on effector functions, as is the case when an antibody inhibits a receptor-ligand interaction or agonizes a receptor.
