Tomas Maira-Litran has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10919956
    Abstract: The invention relates to compositions of a deacetylated poly N-acetylated glucosamine (dPNAG) of Staphylococci. The dPNAG may be isolated from natural sources or synthesized de novo. The invention also relates to the use of dPNAG as a vaccine for inducing active immunity to infections caused by Staphylococcus aureus, S. epidermidis, other related coagulase-negative or coagulase-positive Staphylococci, and other organisms carrying the ica (intracellular adhesion) locus. The invention further provides methods of use for antibodies directed to dPNAG, particularly for inducing passive immunity to the same class of infections.
    Type: Grant
    Filed: November 12, 2003
    Date of Patent: February 16, 2021
    Assignee: The Brigham and Women's Hospital, Inc.
    Inventors: Gerald B. Pier, Tomas Maira-Litran
  • Patent number: 8933218
    Abstract: The present application describes a process for conjugating a PNAG which is less than 40% N-acetylated to a carrier protein.
    Type: Grant
    Filed: March 29, 2007
    Date of Patent: January 13, 2015
    Assignee: GlaxoSmithKline Biologicals s.a.
    Inventors: Ralph Leon Biemans, Pierre Duvivier, Tomas Maira-Litran
  • Patent number: 8703148
    Abstract: 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. Vaccines, methods of treatment using and processes to make an immunogenic composition comprising PNAG and Type 5 and/or 8 capsular polysaccharides are also described.
