  • Patent number: 11932702
    Abstract: The present technology aims at providing a novel type of drug for treating a subject suffering from cancer. Specifically, the technology provides polypeptides comprising at least four immunoglobulin single variable domains (ISVDs), characterized in that one ISVD binds to TCR and at least two ISVDs bind to GPC3. The present technology also provides nucleic acids, vectors and compositions.

  • 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: 11149086
    Abstract: The present invention relates to immunoglobulins that specifically bind Kv1.3 and more in particular to polypeptides, nucleic acids encoding such polypeptides; to methods for preparing such polypeptides; to compositions and in particular to pharmaceutical compositions that comprise such polypeptides, for prophylactic, therapeutic or diagnostic purposes. In particular, the immunoglobulins of the present invention inhibit the activity of Kv1.3.
