  • Publication number: 20230142731
    Abstract: Disclosed herein are methods for treating patients that may develop or already have pre-existing gene therapy neutralizing antibodies by administering a protease that cleaves peptide bonds present in immunoglobulins or by administering a glycosidase that cleaves carbohydrate residues present on immunoglobulins, or other similar enzymatic cleavage of immunoglobulins in vivo.

  • Publication number: 20220047701
    Abstract: The present invention relates to a method of treating HER2/NEU overexpressing cancers. The inventors discovered that the heme-mediated formation of dimers and in general oligomers of Trastuzumab is associated with an improved complement-mediated cytotoxicity on breast cancer cells. The present data highlight that the sensitivity to heme of Trastuzumab, may have major repercussion on its therapeutic activity. Thus the invention relates to the combination of an HER2/neu antibody with a heme and/or of its oligomers and its therapeutic composition in the HER2/NEU characteristic cancer treatment.

  • Publication number: 20170072032
    Abstract: Constructs and methods for inducing immune tolerance during gestation, e.g. in utero, are provided. The constructs comprise a moiety that targets and binds to the neonatal Fc receptor (FcRn) and a moiety comprising an antigen of interest for which immune tolerance is desired. Administration of the constructs to a fetus during gestation results in immune tolerance, e.g. to antigens that otherwise elicit an unwanted immune response such as an autoimmune reaction.

  • Patent number: 8591149
    Abstract: The disclosure concerns a fusible shutter for a water structure such as a river sill, or a spillway on a dam or on a protective dyke, including a solid element disposed on the top of the structure and held on top by gravity, forming a watertight or substantially watertight wall, installed on the water structure and being able to retract so as to allow water to pass without obstruction when the level of the reservoir or watercourse reaches a predefined level, a chamber being formed at the base of the solid element between the latter and the surface that supports it, pressurization means enabling the chamber to be filled with water in order to create under the solid element a thrust directed upwards when the water in the reservoir or watercourse reaches the predefined level.
