  • Publication number: 20220213226
    Abstract: The present invention concerns antigen binding proteins that bind TL1A, including bispecific antigen binding proteins (e.g., antibodies) to TL1A and TNF-?. Such bispecific antibodies can be in a tetrameric immunoglobulin format, in which one heavy chain-light chain pair of the antibody is directed to TL1A and the other to TNF-?. The bispecific antigen binding proteins may also be comprised in an IgG-scFv fusion, in which a conventional tetrameric antibody directed to one antigen is fused to a pair of single chain Fv units directed to the other. The bispecific antigen binding protein may also be comprised in an IgG-Fab fusion, in which a Fab molecule that binds to one antigen is fused to each heavy chain of a conventional tetrameric antibody directed to the other antigen. The invention further relates to uses of the anti-TL1A binding proteins and anti-TL1A/anti-TNF-? antigen binding proteins, and pharmaceutical formulations thereof.

  • Patent number: 11266744
    Abstract: Disclosed is a process for preparing a pharmacologically active compound, in which at least one internal conjugation site of an Fc domain sequence is selected that is amenable to conjugation of an additional functional moiety by a defined conjugation chemistry through the side chain of an amino acid residue at the conjugation site. An appropriate amino acid residue for conjugation may be present in a native Fc domain at the conjugation site or may be added by insertion (i.e., between amino acids in the native Fc domain) or by replacement (i.e., removing amino acids and substituting different amino acids). In the latter case, the number of amino acids added need not correspond to the number of amino acids removed from the previously existing Fc domain. This technology may be used to produce useful compositions of matter and pharmaceutical compositions containing them.
