Patent application numberDescriptionPublished
20080199490Immunogenic Composition - The present application discloses an immunogenic composition comprising a Hib saccharide conjugate and at least two further bacterial saccharide conjugates wherein the Hib conjugate is present in a lower saccharide dose than the mean saccharide dose of all the at least two further bacterial saccharide conjugates.08-21-2008
20090136541IMMUNOGENIC COMPOSITION - The present application discloses an immunogenic composition comprising at least 2 different 05-28-2009
20090252759IMMUNOGENIC COMPOSITION - The present application relates to an immunogenic composition comprising at least 2 conjugates of 10-08-2009
20090311285VACCINE - The present invention relates to immunogenic compositions or vaccines comprising a Vi capsular saccharide-protein carrier conjugate, methods of making the immunogenic compositions or vaccines and uses thereof.12-17-2009
20100143399PROCESS FOR MANUFACTURING VACCINES - The present application discloses a method for making an immunogenic composition comprising an improved way of conducting saccharide-protein conjugation reactions using carbodiimide condensation chemistry. Depending on the nature of the saccharide or protein carrier involved, the quality of the conjugate may be improved by adding one of the reaction components slowly to the reaction mixture. In addition, the conjugate is mixed with a staphylococcal antigen. Immunogenic compositions are further provided comprising the saccharide-protein conjugates made by the methods disclosed.06-10-2010
20100215686Process for Manufacturing Vaccines - The present application discloses an improved method for conducting saccharide-protein conjugation reactions using carbodiimide condensation chemistry. Depending the nature of the saccharide or protein carrier involved, the quality of the conjugate may be improved by adding one of the reaction components slowly to the reaction mixture. Immunogenic compositions are further provided comprising the saccharide-protein conjugates made by the methods disclosed.08-26-2010
20100303852CONJUGATION PROCESS FOR PNAG AND A CARRIER PROTEIN - The present application describes a process for conjugating a PNAG which is less than 40% N-acetylated to a carrier protein.12-02-2010
20100322959IMMUNOGENIC COMPOSITION - The present application relates to immunogenic compositions comprising staphylococcal PNAG which is less than 40% N-acetylated and is conjugated to a carrier protein by a linker bonded to an amine group on PNAG to form a PNAG conjugate. Methods of using and processes to make an immunogenic composition are also described.12-23-2010
