  • Publication number: 20230211006
    Abstract: The present invention relates to dimers comprising a first polypeptide and a second polypeptide, wherein each of said first and second polypeptide comprises at least one immunoglobulin single variable domain (ISVD) and a C-terminal extension comprising a cysteine moiety (preferably at the C-terminus), wherein said first polypeptide and said second polypeptide are covalently linked via a disulfide bond between the cysteine moiety of said first polypeptide and the cysteine moiety of said second polypeptide, in which the dimer outperformed the benchmark constructs, e.g. cognate multivalent and multispecific constructs, in various assays. The present invention provides methods for making the dimers of the invention.

  • Patent number: 11649290
    Abstract: The present invention provides molecules, such as ISVDs and Nanobodies, that bind to CTLA4 or human serum albumin. These molecules have been engineered so as to reduce the incidence of binding by pre-existing antibodies in the bodies of a subject administered such a molecule. Methods for increasing immune response, treating cancer and/or treating an infectious disease with such molecules are provided.

  • Publication number: 20220324951
    Abstract: The present invention relates to glycosylated immunoglobulin variable domains, and in particular to glycosylated immunoglobulin single variable domains (the latter also being referred to herein by means of the abbreviation “ISV” or “ISVD”). The present invention relates to glycosylated immunoglobulin heavy-chain variable domains (also referred to herein as “VH domains”), and in particular to glycosylated immunoglobulin heavy-chain ISVD's. The invention in particular relates to immunoglobulin (single) variable domains that are glycosylated in such a way that the binding of said immunoglobulin (single) variable domains by so-called “pre-existing antibodies” is prevented and/or reduced (i.e. partially or essentially completely) compared to the same immunoglobulin (single) variable domain without the glycosylation of the invention being present.
