  • Publication number: 20230265185
    Abstract: Herein are provided anti-CD22 single domain antibodies (sdAb) prepared by immunizing a llama with the extracellular domain of the predominant human CD22 isoform. By constructing a library of the heavy chain repertoire generated, VHH antibodies specific to the immunogen were isolated. The 27 example antibodies initially produced comprise CDR1, CDR2, and CDR3 sequences corresponding, respectively to SEQNOs: 1-3, 4-6, 7-9, 10-12, 13-15, 16- 18, 19-21, 22-24, 25-27, 28-30, 31-33, 34-36, 37-39, 40-42, 43-45, 46-48, 49-51, 52-54, 55- 57, 58-60, 61-63, 64-66, 67-69, 70-72, 73-75, 75-78, and 79-81; and related sequences. Also provided are multivalent antibodies comprising any one of the sdAbs, including bispecific T-cell engagers, bispecific killer cell engagers (BiKEs), and trispecific killer cell engagers (TriKEs). Also described are chimeric antigen receptors (CARs) for CAR-T therapy comprising any one of the aforementioned sdAbs. Uses of these molecules in the treatment of cancer are also described.

  • Patent number: 10259864
    Abstract: Campylobacter jejuni is a leading cause of bacterial food-borne diseases in humans, ranging from acute diarrheal disease to neurological disorders. An isolated or purified antibody or fragment thereof specific to C. jejuni is described. The antibody or fragment thereof binds to a flagellar protein and reduces motility of C. jejuni. The antibody or fragment thereof is derived from a heavy chain IgG variable domain fragment (VHH) of a camelid animal immunized with C. jejuni flagellar protein. A multivalent form, as well as a phage format, of the antibody or fragment thereof is described. Methods of reducing presence of C. jejuni in an animal or an animal environment, methods and formulations for treating C. jejuni infection, and method of detecting C. jejuni are also described.

  • Patent number: 10112998
    Abstract: The blood-brain barrier (BBB) prevents transport of molecules larger than 500 Dal tons from blood to brain. Receptor-mediated transcytosis (RMT) facilitates transport across the BBB of specific molecules that bind receptors on brain endothelial cells that form the BBB. An insulin-like growth factor 1 receptor (IGF 1R)-binding antibody or fragment thereof is identified that transmigrates the BBB by RMT. The antibody or fragment is used to deliver a cargo molecule across the BBB, wherein the cargo molecule may be a therapeutic or detectable agent. The antibody is a camelid VHH, prepared by immunizing a llama with a 933-amino acid IGF 1R polypeptide. Humanized forms of the camelid VHH are also generated.

    Abstract: The present invention relates to non-aggregating VH domains or libraries thereof. The VH domains comprise at least one disulfide linkage-forming cysteine in at least one complementarity-determining region (CDR) and an acidic isoelectric point (pI). A method of increasing the power or efficiency of selection of non-aggregating VH domains comprises panning a phagemid-based VH domain phage-display library in combination with a step of selecting non-aggregating phage-VH domains. Compositions of matter comprising the non-aggregating VH domains, as well as methods of use are also provided.
