  • Publication number: 20230381341
    Abstract: The present invention relates to recombinant adeno-associated viruses (rAAVs) having capsid proteins that have a tropism for ocular tissue. The rAAVs have capsids that have enhanced or increased transduction of ocular tissues as compared to reference rAAVs. Such rAAVs may be useful in delivering transgenes encoding therapeutic proteins for the treatment of ocular disease.

  • Publication number: 20230323366
    Abstract: The present disclosure relates to gene therapy targeting GluK2 subunit that can be used to inhibit epileptiform discharges. Short interfering RNA sequences against the human Grik2 gene sequence are described which are efficient in decreasing the expression of GluK2-containing KARs in neurons engineered to express the equivalent shRNA or miRNA. Using a tissue culture model of TLE, the examples remarkably demonstrate that viral expression of shRNA or miRNA inhibits the frequency of epileptiform discharges. Therefore, RNA therapeutics aimed at decreasing the expression of GluK2-containing KARs in neurons can remarkably prevent spontaneous epileptiform discharges in TLE. In particular, the present disclosure relates to a recombinant antisense oligonucleotide that targets a Grik2 mRNA.

The fully human post-translationally modified therapeutic monoclonal antibodies may be delivered by gene therapy methods, e.g., as a recombinant adeno-associated vims (rAAV) vector to the appropriate tissue. Methods of manufacture of the AAV vectors, pharmaceutical compositions and methods of treatment are also provided. In addition, provided are methods of producing therapeutic antibodies that are “biobetters” as fully human post-translationally modified. These fully human post-translationally modified therapeutic antibodies may be administered to a subject in need of treatment with the therapeutic antibody.

  • Publication number: 20220186256
    Abstract: The present invention relates to recombinant adeno-associated viruses (rAAVs) having capsid proteins engineered to include amino acid sequences that confer and/or enhance desired properties. In particular, the invention provides engineered capsid proteins comprising peptide insertions from heterologous proteins inserted within or near variable region IV (VR-IV) of the virus capsid, such that the insertion is surface exposed on the AAV particle. The invention also provides capsid proteins that direct rAAVs to target tissues, in particular, capsid proteins comprising peptides derived from erythropoietin or dynein that are inserted into surface-exposed variable regions and that target rAAVs to retinal tissue and/or neural tissue, including the central nervous system, and deliver therapeutics for treating neurological and/or eye disorders.

  • Publication number: 20210010025
    Abstract: Compositions and methods are described for the delivery of a fully human post-translationally modified (HuPTM) therapeutic VEGF-Trap (VEGF-TrapHuPTM)—to a human subject diagnosed with an ocular disease or condition or cancer associated with neovascularization and indicated for treatment with the therapeutic mAb. Delivery may be advantageously accomplished via gene therapy—e.g., by administering a viral vector or other DNA expression construct encoding the VEGF-TrapHuPTM to a patient (human subject) diagnosed with an ocular condition or cancer indicated for treatment with the VEGF-Trap—to create a permanent depot in a tissue or organ of the patient that continuously supplies the VEGF-TrapHuPTM, i.e., a human-glycosylated transgene product. Alternatively, the VEGF-TrapHuPTM, for example, produced in cultured human cell culture, can be administered to the patient for treatment of the ocular disease or cancer.
