  • Patent number: 9926382
    Abstract: The invention provides novel bispecific monoclonal antibodies carrying a different specificity for each binding site of the immunoglobulin molecule and methods for producing novel bispecific monoclonal antibodies carrying a different specificity for each binding site of the immunoglobulin molecule. The antibodies are composed of a single heavy chain and two different light chains, one containing a Kappa constant domain and the other of a Lambda constant domain. The invention provides methods for the isolation of antibodies of different specificities but sharing a common heavy chain. The invention also provides methods for the controlled co-expression of two light chains and a single heavy chain leading to the assembly of monospecific and bispecific antibodies.

  • Patent number: 9850304
    Abstract: The present invention is related to antibodies directed to the antigen CD3 and uses of such antibodies. In particular, the present invention provides fully human monoclonal antibodies directed to CD3. Nucleotide sequences encoding, and amino acid sequences comprising, heavy and light chain immunoglobulin molecules, particularly sequences corresponding to contiguous heavy and light chain sequences spanning the framework regions and/or complementarity determining regions (CDR's), specifically from FR1 through FR4 or CDR1 through CDR3, are provided. Hybridomas or other cell lines expressing such immunoglobulin molecules and monoclonal antibodies are also provided.

  • Publication number: 20170298129
    Abstract: Disclosed are processes for producing a variant polypeptide (e.g. antibodies) having modified binding characteristics for human Fc gamma receptor IIA (CD32A) leading to increased inhibition of proinflammatory mediators while retaining binding to a target antigen via its Fv portion, which processes comprise altering the polypeptides by substitution of at least two amino acid residues at EU position 325, 326 or 328 of a human IgG CH2 region for a sequence selected from SAAF, SKAF, NAAF and NKAF. The polypeptides that can be generated according to the methods of the invention are highly variable, and they can include antibodies and fusion proteins that contain an Fc region or a biologically active portion thereof.

  • Publication number: 20170298140
    Abstract: This invention relates generally to methods and compositions for diagnosing and treating disorders associated with elevated levels of Toll-like Receptor 4 (TLR4) ligands and other biomarkers. The invention also relates to methods of treating, delaying the progression of, or otherwise ameliorating a symptom of a disorder associated with elevated levels of TLR4 ligands and other biomarkers using agents that interfere with or otherwise antagonize TLR4 signaling, including neutralizing anti-TLR4 antibodies.

  • Publication number: 20170291943
    Abstract: The invention relates to fully human antibodies, and fragments thereof, that bind to human interferon gamma (hIFN?), thereby modulating the interaction between IFN? and its receptor, IFN?-R, and/or modulating the biological activities of IFN?. The invention also relates to the use of such anti-IFN? antibodies in the prevention or treatment of immune-related disorders and in the amelioration of a symptom associated with an immune-related disorder.

    Abstract: Disclosed are processes for producing a variant polypeptide (e.g. antibodies) having modified binding characteristics for human Fc gamma receptor IIA (CD32A) leading to increased inhibition of proinflammatory mediators while retaining binding to a target antigen via its Fv portion, which processes comprise altering the polypeptides by substitution of at least two amino acid residues at EU position 325, 326 or 328 of a human IgG CH2 region for a sequence selected from SAAF, SKAF, NAAF and NKAF. Also disclosed are molecules, particularly polypeptides, more particularly immunoglobulins (e.g. antibodies) that include a variant CDR3 region, wherein the variant CDR3 region includes at least one amino acid modified relative to a wild-type CDR3 region. The polypeptides that can be generated according to the methods of the invention are highly variable, and they can include antibodies and fusion proteins that contain an Fc region or a biologically active portion thereof.
