  • Patent number: 10703802
    Abstract: The present invention provides a composition comprising at least two influenza A virus-neutralizing binding molecules that bind to an epitope in the stem region of influenza A virus hemagglutinin (HA) protein, the method comprising: i) a first binding molecule capable of neutralizing at least one influenza A virus subtype selected from the group consisting of H1, H2, H5 and H9; ii) a second binding molecule capable of neutralizing at least one influenza A virus subtype selected from the group consisting of H1, H3, H5, H7 and H9. The mixed composition of the present invention can effectively neutralize the multiple influenza subtypes of both phylogenetic group 1 and phylogenetic group 2 and can be used in combination with a chemical compound. Thus, the composition of the present invention is very useful for the prevention and treatment of a disease by influenza virus.

  • Patent number: 10507240
    Abstract: The present invention relates to an epitope specific to hepatitis B virus surface antigen and a binding molecule binding to the same for neutralizing hepatitis B virus. Since the epitope provided by the present invention is produced by forming a three-dimensional structure and does not comprise a determinant, by which escape mutation is induced against an administration of existing vaccines or HBIg, a composition comprising an antibody biding to the epitope or a vaccine composition comprising the epitope has a very low possibility of causing a decrease in efficacy due to escape mutation. Therefore, such an antibody or vaccine composition can be very effectively used in prevention and/or treatment of HBV.

  • Patent number: 9834594
    Abstract: The present invention relates to human monoclonal antibodies derived from human B cells present in the blood of patients who had recovered from infection with influenza A viruses, wherein the monoclonal antibodies have neutralizing activity against influenza A viruses. The anti-influenza A virus monoclonal antibody of the present invention has binding and neutralizing activities against at least one influenza A virus selected from the group consisting of influenza A virus H1, H2 and H5 subtypes, and thus it is useful for the prevention and treatment of a disease caused by the influenza A virus and is also useful for diagnosis of influenza A virus infection.
