  • Patent number: 11780907
    Abstract: The present invention provides monoclonal antibodies, or antigen-binding fragments thereof, that bind to the influenza hemagglutinin (HA) protein, pharmaceutical compositions comprising the antibodies and methods of use. The antibodies of the invention are useful for inhibiting or neutralizing influenza virus activity, thus providing a means of treating or preventing influenza infection in humans. In some embodiments, the invention provides for use of one or more antibodies that bind to the influenza HA for preventing viral attachment and/or entry into host cells. The antibodies of the invention may be used prophylactically or therapeutically and may be used alone or in combination with one or more other anti-viral agents or vaccines.

  • Patent number: 9498529
    Abstract: The present invention provides methods for treating or preventing influenza virus infection. The methods of the present invention comprise administering to a subject in need thereof a pharmaceutical composition comprising a type II transmembrane serine protease (TTSP) inhibitor. The TTSP inhibitor preferably functions by inhibiting the proteolytic cleavage of influenza hemagglutinin (HA0) into the functional subunits HA1 and HA2. In certain embodiments, the TTSP inhibitor is an inhibitor of transmembrane protease serine S1 member 2 (TMPRSS2), such as an anti-TMPRSS2 antibody or antigen-binding fragment thereof.
