    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.
