  • Publication number: 20140050763
    Abstract: The present invention relates to a method for reducing the occurrence and severity of infectious diseases, especially infectious diseases in which lipid-containing infectious viral organisms are found in biological fluids, such as blood. The present invention employs solvents useful for extracting lipids from the lipid-containing infectious viral organism thereby creating modified viral particles with reduced infectivity and enhanced antigenicity. The present invention provides vaccine compositions, comprising these modified viral particles with reduced infectivity and enhanced antigenicity, optionally combined with a pharmaceutically acceptable carrier or an immunostimulant. The vaccine composition is administered to a patient to provide protection against the lipid-containing infectious viral organism. The vaccine compositions of the present invention include combination vaccines of modified viral particles obtained from one or more strains of a virus and/or one or more types of virus.

  • Publication number: 20120308615
    Abstract: The present invention is related with the field of the therapeutic immunization, specifically with the employment of a new formulation of antigens of the Hepatitis B Virus (HBV) for the cellular stimulation. The formulation is formed by the surface antigens (HBsAg) precipitated in suspension and the nucleocapsid (HBcAg) of the HBV. The formulation contains these antigens like suspended particles of sizes less than 500 nm and higher than 500 nm, in a mixture where the proportion among the particles of the mentioned sizes is among 50%-50% and 80%-20%, respectively. The selection of a range of sizes of particles allows that the levels of stimulation of several cellular types are maximized. Additionally, a cellular stimulation method is described with this formulation, and the later passive immunization of patients with chronic Hepatitis B, based on the maximum stimulation in vivo or in vitro using heterologous or autologous cells (dendritic cells, B cells and macrophages).

The injectable needles are hard enough to penetrate the skin and can be administered percutaneously by simple pusher or injector delivery devices. The manufacturing procedure of the injectable needles allows for the incorporation of the drug as preformulated stable microparticles and incorporation of modifying agents to modulate stiffness, solubility and drug release. Drugs formulated in these injectable needles offer a safe, simple and effective alternative to conventional percutaneous drug delivery systems based on hypodermic needles and syringes that require refrigerated storage and reconstitution prior to administration.

  • Publication number: 20120148621
    Abstract: The present invention is directed to a method for promoting or stimulating a cell-mediated immune response to an antigen, by administering a target antigen (such as a protein) with a transport factor that contains a fragment of a bipartite protein exotoxin, but not the corresponding protective antigen. Preferred transport factors include the protective antigen binding domain of lethal factor (LFn) from B. anthracis, consisting of amino acids 1-255, preferably a fragment of at least 80 amino acids that shows at least 80% homology to LFn, and a fragment of about 105 amino acids from the carboxy portion that does not bind PA. The target antigen can include any molecule for which it would be desirable to elicit a CMI response, including viral antigens and tumor antigens.

  • Publication number: 20120114692
    Abstract: Immunogenic compositions containing phospholipid adjuvants, including microparticle and emulsion compositions. According to one aspect of the invention, an immunogenic microparticle composition is provided comprising: water; a polymer microparticle; an antigen adsorbed to the microparticle; and a phospholipid compound, e.g., a synthetic phospholipid compound comprising: (i) one or more phosphoryl groups independently selected from a phosphato group and a phosphodiester group; (ii) a plurality of linear alkane groups. According to another aspect of the invention an immunogenic emulsion composition is provided that comprises: water; a metabolizable oil; an emulsifying agent; an antigen; and a phospholipid compound, e.g., a synthetic phospholipid compound like that above. The emulsion composition is an oil-in-water emulsion having oil and aqueous phases, in which the oil phase is in the form of oil droplets, substantially all of which are less than 1 micron in diameter.

  • Patent number: 8173411
    Abstract: The present invention relates to a method of drying biological and other labile samples so that they can be preserved as a highly viscous liquid. The method involves the steps of preparing a preservation sample by dissolving/suspending an active agent in a solution of a stabilizing agent, subjecting the preservation sample to such temperature and pressure conditions that the preservation sample looses solvent by evaporation without freezing or bubbling to form a foam and removing solvent until the preservation sample dries to form a highly viscous liquid. The stabilizing solution comprises a glass forming polyol and a second component which decreases the flow rate of the highly viscous liquid formed by the method.

  • Publication number: 20120093770
    Abstract: The invention relates to the discovery of novel soluble neutral active Hyaluronidase Glycoproteins (sHASEGPs), methods of manufacture, and their use to facilitate administration of other molecules or to alleviate glycosaminoglycan associated pathologies. Minimally active polypeptide domains of the soluble, neutral active sHASEGP domains are described that include asparagine-linked sugar moieties required for a functional neutral active hyaluronidase domain. Included are modified amino-terminal leader peptides that enhance secretion of sHASEGP. The invention further comprises sialated and pegylated form of a recombinant sHASEGP to enhance stability and serum pharmacokinetics over naturally occurring slaughterhouse enzymes. Further described are suitable formulations of a substantially purified recombinant sHASEGP glycoprotein derived from a eukaryotic cell that generate the proper glycosylation required for its optimal activity.

  • Patent number: 8138318
    Abstract: This invention relates to a nucleic acid molecule encoding a middle Hepatitis B virus (HBV) surface protein, a vector comprising the nucleic acid molecule, a host cell comprising the vector, and a composition comprising the expression products of this vector, which may comprise middle HBV surface protein, or a mixture of middle HBV surface protein and small HBV surface protein. The compositions of the invention may be useful for expressing a middle HBV surface protein, or a mixture of small and middle HBV surface proteins in defined ratios, determining the binding of an antibody to a middle or small HBV surface protein, determining the quality of an anti-middle or an anti-small HBV surface protein antibody, or determining the quality of a kit containing anti-middle or anti-small HBV surface protein antibodies.

  • Publication number: 20120045430
    Abstract: Various nucleic acid-based matrixes are provided, comprising nucleic acid monomers as building blocks, as well as nucleic acids encoding proteins, so as to produce novel biomaterials. The nucleic acids are used to form dendrimers that are useful as supports, vectors, carriers or delivery vehicles for a variety of compounds in biomedical and biotechnological applications. In particular, the macromolecules may be used for the delivery of drugs, genetic material, imaging components or other functional molecule to which they can be conjugated. An additional feature of the macromolecules is their ability to be targeted for certain organs, tumors, or types of tissues. Methods of utilizing such biomaterials include delivery of functional molecules to cells.

    Abstract: HBsAg is expressed in a Saccharomyces cerevisiae host, carrying a plasmid having a HBsAg coding sequence, wherein the plasmid includes: (1) an upstream promoter from a glyceraldehyde-3-phosphate dehydrogenase gene, for controlling expression of the HBsAg coding sequence; and (2) an ARG3 transcription terminator downstream of the HBsAg coding sequence. The plasmids may also include: (3) a LEU2 selection marker; (4) a 2? plasmid sequence; and (5) an origin of replication functional in Escherichia coli. HBsAg can be expressed in this host, and can be purified for use in the manufacture of vaccines, and in particular for the manufacture of combination vaccines and in new monovalent HBV vaccines e.g. with non-alum adjuvants.
