Stefan Michelfelder 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).

  • Publication number: 20240083942
    Abstract: The invention relates to peptides, polypeptides or proteins which specifically bind to cells of the brain and/or the spinal cord. The peptides, polypeptides or proteins can be part of a viral capsid, and they can be used for guiding a recombinant viral vector selectively to the brain and/or spinal cord after systemic administration to a subject, where it provides for a tissue-specific expression of one or more transgenes. The invention therefore also relates to a recombinant viral vector, preferably an AAV vector, comprising a capsid containing at least one of the peptides, polypeptides or proteins of the invention and at least one transgene which is packaged within the capsid. The viral vector is particularly suitable for the therapeutic treatment of a disease or functional disorder of the brain and/or the spinal cord. The invention further relates to cells and pharmaceutical compositions comprising the viral vector of the invention.

  • Publication number: 20240076689
    Abstract: This invention generally relates to the field of somatic gene therapy. The invention provides a nucleic acid construct comprising a transgene encoding a therapeutic protein, a tetracycline-responsive aptazyme sequence, and inverted terminal repeats (ITRs). The nucleic acid construct can be transferred to a subject in need thereof in the form of a viral vector, in particular an adeno-associated virus (AAV) vector. The Tet-responsive aptazyme sequence allows for a tightly controlled expression of the transgene in the subject, thereby avoiding toxic side effects. The nucleic acid construct and the viral vectors comprising same are particularly useful in the treatment of proliferative diseases like cancer.

  • Publication number: 20230181683
    Abstract: The invention relates to a peptide, polypeptide, or protein that binds specifically to cells of the lung endothelium. The peptide, polypeptide, or protein can be a component of a viral capsid and can be used to lead a recombinant viral vector selectively to the lung endothelial tissue after systemic administration to a subject and to ensure tissue-specific expression of one or more transgenes there. The invention thus further relates to a recombinant viral vector, preferably an AAV vector, which comprises a capsid comprising the peptide, polypeptide, or protein according to the invention and which comprises at least one transgene packaged in the capsid. The viral vector is suitable in particular for the therapeutic treatment of a lung disorder or a lung disease. The invention further relates to cells and pharmaceutical compositions which comprise the viral vector according to the invention.
