Abstract: CH1 domain variants engineered for preferential binding to either a kappa CL domain or a lambda CL domain, as well as polypeptides, e.g., antibody heavy chains or antibodies, comprising such engineered CH1 domain variants, and pharmaceutical compositions comprising such CH1 domain variants and/or such polypeptides, and methods for making and using such CH1 domain variants are provided. The CH1 domain variants minimize heavy chain-light chain mispairing and promote cognate heavy chain-light chain pairing, thereby improving the generation of multispecific, e.g., bispecific, antibodies. Also provided are methods of making CH1 domain variant libraries and methods of identifying one or more CH1 domain variants.

Abstract: Anti-CD3 binding domains and antibodies comprising them, including multispecific antibodies, with, inter alia, desirable T-cell activation and (re)directed target cell killing potency and developability, profiles are provided, as well as methods for their identification, isolation, and generation, and methods for their preparation and use. Reagents for identifying, isolating, selecting, generating and characterizing CD3 binding domains and antibodies comprising them are also provided.

Abstract: A method of broadening epitopic coverage of an antigen of interest, wherein a first sample of the antigen of interest is contacted with a first plurality of host cells collectively expressing a first library of antibodies. Host cells expressing antibodies that bind to the antigen are then collected from among the first plurality of host cells, and a composition is prepared comprising a polyclonal mixture of antibodies expressed by these host cells. A second sample of the antigen of interest is then contacted with an aliquot of the prepared composition and a second plurality of host cells collectively expressing a second library of antibodies. Host cells expressing antibodies that bind to the second sample of the antigen are then collected from among the second plurality of host cells.

Abstract: The present invention provides Fc variants and polypeptides, e.g., antibodies and Fc fusion proteins, comprising such Fc variants. In particular, Fc variants with diminished effector function as a consequence of hinge region and CH2 domain mutations, e.g., LALE-PG, are provided. Such variants maintain antigen-binding and favorable developability profiles and may display improved expressability.

Abstract: The present invention provides an antibody that specifically binds to proprotein convertase subtilisin/kexin type 9 (PCSK9), an antigen-binding fragment of the antibody, and a composition comprising the antibody or the fragment. Also provided are a nucleic acid that encodes the antibody or the fragment, a host cell containing the nucleic acid, and applications of the antibody and fragment in treatment and diagnosis.
