  • Patent number: 10253091
    Abstract: By altering amino acid sequences, the present inventors successfully produced constant regions that can confer antibodies with particularly favorable properties for pharmaceutical agents. When used to produce antibodies, the altered constant regions produced according to the present invention significantly reduce heterogeneity. Specifically, the antibody homogeneity can be achieved by using antibody heavy chain and light chain constant regions introduced with alterations provided by the present invention. More specifically, the alterations can prevent the loss of homogeneity of antibody molecules due to disulfide bond differences in the heavy chain. Furthermore, in a preferred embodiment, the present invention can improve antibody pharmacokinetics as well as prevent the loss of homogeneity due to C-terminal deletion in antibody constant region.

  • Patent number: 10251377
    Abstract: The present invention relates to humanisation of antibodies in vivo. The invention provides non-human vertebrates, cells, populations and methods useful for humanising chimaeric antibodies in vivo. Using the present invention it is possible straightforwardly and rapidly to obtain antigen-specific antibodies that are fully human (ie, comprising human variable and constant regions) and have undergone recombination, junctional diversification, affinity maturation and isotype switching in vivo in a non-human vertebrate system. Furthermore, such antibodies are humanised (eg, totally human)—and selected—totally in vivo, and as such the present invention harnesses in vivo filtering for expressibility, affinity and biophysical characteristics in the context of the desired human variable and constant region pairings. This is avoids problems of down-grading antibody characteristics when humanising the constant region of chimaeric antibodies in vitro.

  • Patent number: 10196453
    Abstract: Clostridium difficile is the most common hospital acquired pathogen in the United States, and infection is in many cases fatal. Toxins A and B are its major virulence factors, but increasingly a third toxin may be present, known as C. difficile transferase (CDT). An ADP-ribosyltransferase that causes actin cytoskeletal disruption, CDT is typically produced by the major, hypervirulent strains and has been associated with more severe disease. It is disclosed herein that CDT enhances the virulence of two PCR-ribotype 027 strains in mice. The toxin induces pathogenic host inflammation via a novel Toll-like Receptor 2 (TLR2) dependent pathway, resulting in the suppression of a protective host eosinophilic response. Finally, it is disclosed that restoration of TLR2 deficient eosinophils is sufficient for protection from a strain producing CDT. These findings offer an explanation for the enhanced virulence of CDT-expressing C.

    Abstract: The present invention provides antibodies that bind to prostate-specific membrane antigen (PSMA), bispecific antibodies that bind to PSMA and CD3, and methods of using the same. According to certain embodiments, the antibodies of the invention bind human PSMA with high affinity and bind CD3 to induce human T cell proliferation. The invention includes antibodies that bind PSMA and CD3 and induce T cell-mediated killing of PSMA-expressing tumor cells. According to certain embodiments, the present invention provides bispecific antigen-binding molecules comprising a first antigen-binding domain that specifically binds human CD3, and a second antigen-binding molecule that specifically binds human PSMA. In certain embodiments, the bispecific antigen-binding molecules of the present invention are capable of inhibiting the growth of prostate tumors expressing PSMA.

  • Patent number: 10174114
    Abstract: The present invention concerns compositions and methods of use of humanized anti-HLA-DR antibodies. In preferred embodiments, the antibodies induce apoptosis and inhibit proliferation of lymphoma cells without inducing CDC or ADCC. In more preferred embodiments, the humanized anti-HLA-DR antibodies bind to the same epitope of HLA-DR as, or compete for binding to HLA-DR with, a murine L243 antibody. Most preferably, the humanized anti-HLA-DR antibody exhibits a higher affinity for HLA-DR than the parental murine antibody. The humanized HLA-DR antibody is of use for therapy of various diseases such as cancer, autoimmune disease or immune dysregulatory function, and is of particular use for therapy of B cell lymphomas and leukemias. In most preferred embodiments, the humanized anti-HLA-DR antibody is capable of inducing at least partial remission of lymphomas that are resistant to other B cell antibodies, such as rituximab.

  • Patent number: 10117949
    Abstract: A recombinant fusion protein comprising a human erythropoietin peptide portion linked to an immunoglobulin peptide portion is described. The fusion protein has a prolonged half-life in vivo in comparison to naturally occurring or recombinant native human erythropoietin. In one embodiment of the invention the protein has a half-life in vivo at least three fold higher than native human erythropoietin. The fusion protein also exhibits enhanced erythropoietic bioactivity in comparison to native human erythropoietin. In one embodiment, the fusion protein comprises the complete peptide sequence of a human erythropoietin (EPO) molecule and the peptide sequence of an Fc fragment of human immunoglobulin IgG1. The Fc fragment in the fusion protein includes the hinge region, CH2 and CH3 domains of human immunoglobulin IgG1. The EPO molecule may be linked directly to the Fc fragment to avoid extraneous peptide linkers and lessen the risk of an immunogenic response when administered in vivo.

  • Patent number: 10106612
    Abstract: Herein is reported a method for producing a bispecific antibody comprising the step of incubating (i) an antibody Fab fragment or a scFv antibody comprising within the 20 C-terminal amino acid residues the amino acid sequence LPX1TG (SEQ ID NO: 01), (ii) a one-armed antibody comprising a full length antibody heavy chain, a full length antibody light chain, and an Fc-heavy chain, whereby the full length antibody heavy chain and the full length antibody light chain are cognate antibody chains that thereof forms an antigen binding site, whereby the full length antibody heavy chain and the Fc-heavy chain are covalently linked to each other via one or more disulfide bonds forming an antibody hinge region, and whereby the Fc-heavy chain has an oligoglycine amino acid sequence at its N-terminus, and (iii) a Sortase A enzyme.

  • Patent number: RE47194
    Abstract: Cysteine engineered anti-MUC16 antibodies are engineered by replacing one or more amino acids of a parent anti-MUC16 antibody with non cross-linked, reactive cysteine amino acids. Methods of design, preparation, screening, and selection of the cysteine engineered anti-MUC16 antibodies are provided. Cysteine engineered anti-MUC16 antibodies (Ab) are conjugated with one or more drug moieties (D) through a linker (L) to form cysteine engineered anti-MUC16 antibody-drug conjugates having Formula I: Ab-(L-D)p ??I where p is 1 to 4. Diagnostic and therapeutic uses for cysteine engineered antibody drug compounds and compositions are disclosed.
