  • Patent number: 10961299
    Abstract: Novel, antibody-based binding agents derived from human and camelid immunoglobulins are described. These binding agents recognize and bind with specificity to Clostridium difficile toxin A and/or toxin B and in some cases exhibit toxin neutralizing activity. These binding agents can be used to treat or prevent primary and recurrent CDI. The binding agents include camelid VHH peptide monomers, linked groups of VHH peptide monomers, VHH peptide monomers joined to antibody Fc domains, and VHH peptide monomers joined to IgG antibodies.
    Type: Grant

  • Patent number: 9951106
    Abstract: Fusion proteins comprising a portion of the HIV-1 Env protein (gp120 and gp140) and single-chain fragment V regions (ScFv) of an enhancing antibody that exhibits binding specificity for HIV-1 Env protein are disclosed that may serve in immunogenic formulations for vaccination against HIV-1 infection, as well as methods of generating an immune response using the fusion proteins.

  • Publication number: 20150299268
    Abstract: Fusion proteins comprising a portion of the HIV-1 Env protein and ScFv of an enhancing antibody are disclosed that may serve in immunogenic formulations for vaccination against HIV-1 infection. A broadly neutralizing antibody and engineered bi-/tri-specific anti-HIV-1 antibodies that may serve in the prevention and/or treatment of HIV-1 infections in a subject are also disclosed, as well as methods of using the fusions proteins and antibodies.

  • Publication number: 20100323401
    Abstract: This invention relates to an in vitro method of producing antigen specific B cells and antibodies that provides for the capture of an entire primary human antibody repertoire for any foreign antigen, allows for screening large numbers of immunogen/adjuvant combinations, and permits the isolation of human monoclonal antibodies on demand thereby obviating the need to immunize humans with the target antigen.
