  • Patent number: 10052373
    Abstract: The present invention provides a protein- and peptide-free conjugate comprising a synthetic carbohydrate and a carrier molecule, wherein the synthetic carbohydrate is a Streptococcus pneumoniae type 3 capsular polysaccharide related carbohydrate and the carrier molecule is a glycosphingolipid. Said conjugate and pharmaceutical composition thereof are useful for immunization against diseases associated with Streptococcus pneumoniae, and more specifically against diseases associated with Streptococcus pneumoniae type 3.
    Type: Grant
    Filed: September 18, 2014
    Date of Patent: August 21, 2018
    Assignee: Max-Planck-Gesellschaft zur Förderung der Wissenschaften e.V.

  • Patent number: 9815889
    Abstract: The present invention relates to an antibody having specificity for an immunogenic determinant consisting of the pentasaccharide repeating unit of the Clostridium difficile glycopolymer PS-I: ?-L-Rhap-(1?3)-?-D-Glcp-(1?4)-[?-L-Rhap-(1?3)]-?-D-Glcp-(1?2)-?-D-Glcp or a fragment thereof. Said antibody is able to prevent and treat diseases caused by C. difficile. The present invention further pertains to a method of treating or preventing a disease caused by the pathogen Clostridium difficile, which comprises administering to a subject said antibody or a vaccine composition comprising said antibody.

  • Patent number: 9238669
    Abstract: The invention relates to a synthetic oligosaccharide representing part of the repeating unit of the Clostridium difficile glycopolymer PS-I and having the sequence of the pentasaccharide a-L-Rhap-(1?3)-?-D-Glcp-(1?4)-[a-L-Rhap-(1?3]-a-D-Glcp-(1?2)-a-D-Glcp or a synthetic fragment or derivative thereof. Preferably, the claimed synthetic oligosaccharide bears at least one linker L for conjugation to a carrier protein or for immobilization on a surface. Further aspects of the invention relate to advantageous methods for synthesizing said synthetic oligosaccharide and oligosaccharide-protein conjugate as well as to uses thereof, in particular as vaccines and diagnostic tools.
