  • Publication number: 20080254065
    Abstract: The invention provides a vaccine for protecting a human patient against infection by a human influenza virus strain, wherein the vaccine comprises an antigen from an avian influenza virus strain that can cause highly pathogenic avian influenza. The antigen can invoke an antibody response in the patient that is capable of neutralising said human influenza virus strain. Whereas the prior art used known non-pathogenic avian strains to generate antibodies in humans against known pathogenic avian strains, the invention uses known pathogenic avian strains to protect against emerging pathogenic human strains. Furthermore, whereas the prior art focused on achieving a close antigenic match between the vaccine strain and the target strain, the invention selects vaccine strains based on their pathogenicity, regardless of any perceived close antigenic relationship to the target strain.

  • Publication number: 20080171071
    Abstract: A highly concentrated, low salt-containing, biologically active syrup form of IGF-I or variant thereof and methods for its preparation are provided. This novel syrup form of IGF-I has an IGF-I concentration of at least about 250 mg/ml, a density of about 1.0 g/ml to about 1.2 g/ml, and a viscosity of about 13,000 centipoise (cps) to about 19,000 cps, as measured at ambient temperature (23° C.). The IGF-I syrup is prepared by precipitating or partitioning IGF-I from solution, preferably by adjusting the solution pH or by use of a solubility enhancer to concentrate IGF-I in solution followed by removal of the solubility enhancer. The precipitated syrup is useful as a means of storing IGF-I in a stable form and as a means of preparing compositions comprising biologically active IGF-I. Pharmaceutical compositions and kits comprising this concentrated IGF-I syrup are provided.

  • Publication number: 20080057070
    Abstract: Methods of therapy for treating diseases mediated by stimulation of CD40 signaling on CD40-expressing cells are provided. The methods comprise administering a therapeutically effective amount of an antagonist anti-CD40 antibody or antigen-binding fragment thereof to a patient in need thereof. The antagonist anti-CD40 antibody or antigen-binding fragment thereof is free of significant agonist activity, but exhibits antagonist activity when the antibody binds a CD40 antigen on a human CD40-expressing cell. Antagonist activity of the anti-CD40 antibody or antigen-binding fragment thereof beneficially inhibits proliferation and/or differentiation of human CD40 expressing cells, such as B cells.
