  • Patent number: 11939395
    Abstract: The present invention provides novel antibodies and methods for using recombinant antigen-binding regions and antibodies and functional fragments containing such antigen-binding regions that are specific for CD38, which plays an integral role in various disorders or conditions. These methods take advantage of newly discovered antibodies and surprising properties of such antibodies, such as the ability to bind CD38 of minipig origin and the ability to induce, by cross-linking, specific killing of cells that express CD38. These antibodies as well as the novel methods for using those antibodies can be used to treat, for example, hematological malignancies such as multiple myeloma.

  • Publication number: 20210253698
    Abstract: The invention relates to multispecific antigen-binding proteins for engaging natural killer (NK) cells for triggering NK cell cytotoxicity by engaging the CD16A (Fc?RIIIA)expressed on NK cells, wherein the antigen-binding protein comprises at least two CD16A antigen-binding moieties and at least a further target antigen-binding moiety. The CD16A antigen-binding moiety comprises light chain and heavy chain variable regions linked one after another in a polypeptide chain and the variable region at the N-terminus of the polypeptide chain comprising the CD16A antigen-binding moiety is a light chain variable region.
