Patents by Inventor Annie DE GROOT

Annie DE GROOT 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: 12264191
    Abstract: The present invention relates to the field of therapeutic proteins, in particular, to recombinant coagulation factors. It provides a recombinant Factor VIII (FVIII) protein comprising specific point mutations at defined positions, which serve to reduce the immunogenicity of said FVIII protein, wherein the Factor VIII protein substantially retains its coagulant activity. It further provides nucleic acids encoding said de-immunized protein, cell lines and methods of recombinant preparation as well as pharmaceutical compositions comprising the recombinant FVIII of the invention, which are advantageous for use in treatment of patients with Hemophilia A, particularly those who have not yet been treated with a FVIII product. Additionally, it can be a safe alternative for previously treated patients and even for patients who have developed an immune-response to FVIII, e.g., for immune-tolerance-induction therapy (ITI/ITT) or rescue ITI.
    Type: Grant

  • Patent number: 12247053
    Abstract: The present invention provides compositions and methods for generation of an anti-influenza immune response. In particular, conserved T cell epitopes within matrix protein and nucleoprotein components of influenza virus have been identified and further screened for those structures that will bind either or both of HLA I and II molecules. Methods for vaccinating subjects with formulations of such peptides for the treatment or prevention of influenza infection also are described.
