  • Patent number: 9334330
    Abstract: The monoclonal antibodies that only recognize the O-acetylated form of the GD2 ganglioside, or fragments of the antibody, for the diagnosis and the treatment of cancers in which the cells express the O-acetylated GD2, the antibody or the fragment recognizing the O-acetylated GD2 molecules expressed by the tumoral cells and not recognizing the GD2 molecules expressed at the surface of the peripheral nerves, in order to increase the specificity of the diagnosis and reduce the toxicity of the treatments. Also artificially modified antibodies advantageously used for treating and diagnosing cancers in which the cells express the O-acetylated GD2.
    Type: Grant
    Filed: December 23, 2014
    Date of Patent: May 10, 2016
    Assignee: UNIVERSITE DE NANTES
