  • Publication number: 20220064327
    Abstract: Bispecific antigen binding molecules (e.g., antibodies) that bind blood clotting factors, factor IXa (FIXa) and factor X (FX), and enhance the FIXa-catalysed activation of FX to FXa.

  • Publication number: 20220000085
    Abstract: The invention provides improved non-human vertebrates and non-vertebrate cells capable of expressing antibodies comprising human variable region sequences. The present invention is directed to the provision of long HCDR3s from non-human vertebrates and cells. The present invention is also directed to the provision of novel V, D and J pairings in immunoglobulin heavy and light chain loci. Novel, biased antibody diversities and potentially expanded diversities are provided. The invention also provides for novel and potentially expanded diversity or diversity that is biased towards variable gene usage common to antibodies useful for treating and/or preventing certain diseases or conditions, such as infectious diseases. The invention also provides methods of generating antibodies using such vertebrates, as well as the antibodies per se, therapeutic compositions thereof and uses.

  • Publication number: 20210395397
    Abstract: Antibodies comprising unpaired variable domains, e.g., heavy chain variable (VH) domains, for binding antigen. Antibody comprising two immunoglobulin (Ig) chains, wherein a first Ig chain comprises a variable domain and a constant domain, and a second Ig chain comprises a constant domain, wherein the second Ig chain lacks a variable domain, leaving the variable domain of the first Ig chain unpaired. The antibody may comprise two Ig heavy chains and two Ig light chains, each heavy chain comprising a VH domain and a constant region comprising a CH1 domain, and each light chain comprising a CL domain, wherein one or both light chains lack a VL domain, thereby leaving one or both VH domains unpaired. Non-human animals (e.g., mice) engineered to produce antibodies having unpaired VH domains, involving deletion of sequence coding for light chain variable (VL) domains. Use of unpaired VH domains to generate antigen-binding molecules.
