    摘要: The present invention relates to novel molecules (Fc variants) comprising at least one antigen binding region and an Fc region that further comprises a modified hinge which alters the binding of Fc to one or more Fc ligand (e.g., FcγRs) and/or modulates effector function. More specifically, this invention provides Fc variants that have modified binding affinity to one or more FcγR and/or C1q. Additionally, the Fc variants have altered antibody-dependent cell-mediated cytotoxicity (ADCC) and/or complement dependent cytotoxicity (CDC) activity. The invention further provides methods and protocols for the application of said Fc variants particularly for therapeutic purposes.

    摘要: The present invention provides methods for preventing, managing, treating and/or ameliorating a Respiratory Syncytial Virus (RSV) infection (e.g., acute RSV disease, or a RSV upper respiratory tract infection (URI) and/or lower respiratory tract infection (LRI)), otitis media (preferably, stemming from, caused by or associated with a RSV infection, such as a RSV URI and/or LRI), and/or a symptom or respiratory condition relating thereto (e.g., asthma, wheezing, and/or reactive airway disease (RAD)) in a subject, comprising administering to said human an effective amount of one or more antibodies that immunospecifically bind to one or more RSV antigens with a high affinity and/or high avidity. In some embodiments, one or more antibodies comprise a modified IgG constant domain, or FcRn-binding fragment thereof resulting in longer in vivo serum half-life. In particular embodiments the methods of the invention comprising administering to subject an effective amount of one or more modified antibodies that immunospecifically bind to one or more RSV antigens with an association rate (kon) of at least 2×105 M−1s−1 and a dissociation rate (koff) of less than 5×10−4 s−1.

    摘要: The present invention relates to novel molecules (Fc variants) comprising at least one antigen binding region and an Fc region that further comprises a modified hinge which improves stability and/or alters the binding of Fc to one or more metal ion and/or one or more Fc ligand (e.g., FcγRs) and/or modulates effector function. More specifically, this invention provides Fc variants that are less susceptible to metal ion-mediated cleavage and/or have modified binding affinity to one or more FcγR and/or C1q. Additionally, the Fc variants have altered antibody-dependent cell-mediated cytotoxicity (ADCC) and/or complement dependent cytotoxicity (CDC) activity. Furthermore, the modified hinge of the Fc variants retains a similar flexibility to the wild type hinge. The invention further provides methods and protocols for the application of said Fc variants particularly for therapeutic purposes.

    摘要: The present invention provides molecules, including IgGs, non-IgG immunoglobulin, proteins and non-protein agents, that have increased in vivo half-lives due to the presence of an IgG constant domain, or a portion thereof that binds the FcRn, having one or more amino acid modifications that increase the affinity of the constant domain or fragment for FcRn. Such proteins and molecules with increased half-lives have the advantage that smaller amounts and or less frequent dosing is required in the therapeutic, prophylactic or diagnostic use of such molecules.

    摘要: The present invention relates to recombinant polynucleotides, expression vectors and methods for the production of multimeric proteins. The vectors and methods are useful for the production of multimeric protein and are unique in that they utilize a minimal number of signal sequences. More specifically, the present invention provides recombinant polynucleotide molecules and expression vectors comprising a promoter region operably linked to a transcription unit. The transcription unit is characterized by at least two DNA sequences encoding distinct polypeptides wherein at least one but not all DNA sequences further encodes a signal sequence operably linked to the DNA sequence encoding a polypeptide. The invention further provides methods of producing a multimeric protein using the expression vectors of the present invention.
