    Abstract: The present disclosure relates to a novel class of anti-HER2 monoclonal antibodies comprising a homogeneous population of anti-HER2 IgG molecules having the same N-glycan on each of Fc. The antibodies of the invention can be produced from anti-HER2 monoclonal antibodies by Fc glycoengineering. Importantly, the antibodies of the invention have improved therapeutic values with increased ADCC activity and increased Fc receptor binding affinity compared to the corresponding monoclonal antibodies that have not been glycoengineered.

    Abstract: Immunogenic compositions comprising partially glycosylated viral glycoproteins for use as vaccines against viruses are provided. Vaccines formulated using mono-, di-, or tri-glycosylated viral surface glycoproteins and polypeptides provide potent and broad protection against viruses, even across strains. Pharmaceutical compositions comprising monoglycosylated hemagglutinin polypeptides and vaccines generated therefrom and methods of their use for prophylaxis or treatment of viral infections are disclosed. Methods and compositions are disclosed for influenza virus HA, NA and M2, RSV proteins F, G and SH, Dengue virus glycoproteins M or E, hepatitis C virus glycoprotein E1 or E2 and HIV glycoproteins gp120 and gp41.

    Abstract: A novel humanized anti-IgE antibody is disclosed. The antibody is capable of binding to free IgE, membrane-bound IgE on B lymphocytes, IgE bound by CD23, but not to IgE bound by high-affinity IgE.Fc receptor on mast cells. The present invention relates to the treatment of IgE-mediated diseases, including allergic asthma, allergic rhinitis, atopic dermatitis, food allergy, chronic spontaneous (idiopathic) urticaria, chronic rhinosinusitis, systemic mastocytosis, cutaneous mastocytosis, allergic bronchopulmonary aspergillosis, recurrent idiopathic angioedema, and eosinophil-associated gastrointestinal disorder by administering the anti-IgE antibody of the present invention.
