  • Patent number: 11499141
    Abstract: The present disclosure relates generally to modified adeno-associated virus (AAV) from serotypes other than serotype 2, which have a viral capsid protein with a subunit 1 (VP1) sequence which is modified relative to the corresponding wildtype sequence. In particular, the modified AAVs of the disclosure comprise site-specific amino acid substitutions within the phospholipase A2 (PLA2) domain and flanking sequence relative to the corresponding wild-type sequence which improve functionality of the AAV when produced in insect cells. The present disclosure also relates to methods of producing the modified AAVs, reagents therefor, baculovirus expression systems and insect cells for producing said modified AAVs.
    Type: Grant

  • Publication number: 20220098614
    Abstract: The present disclosure relates to modified adeno-associated virus (AAV) delivery vectors comprising ‘silence and replace’ DNA constructs, compositions comprising same, and the use of the modified AAV and compositions to treat oculopharyngeal muscular dystrophy (OPMD) in individuals suffering from OPMD or which are predisposed thereto. In particular, the disclosure relates to AAV having a capsid protein with a modified subunit 1 (VP1) and comprising a ‘silence and replace’ DNA construct, wherein the ‘silence and replace’ DNA construct comprises (i) a DNA-directed RNAi (ddRNAi) construct encoding short hairpin microRNA (shmiR) targeting PABPN1 causative of OPMD and (ii) a PABPN1 construct encoding functional PABPN1 protein having a mRNA transcript which is not targeted by the shmiRs at (i). The present disclosure also relates to the methods of treating OPMD comprising direct injection of an AAV of the disclosure to a subject's pharyngeal muscles.

  • Publication number: 20180320180
    Abstract: This invention is directed to an RNA interference (RNAi) agent and the use of that RNAi agent to treat Age-related Macular Degeneration, as well as pharmaceutical compositions containing the RNAi agents of the invention. The RNAi agent is a DNA-directed RNA interference (ddRNAi) agent (being an RNA molecule), together with an expression cassette or construct to express that agent in a cell (including in vivo), for inhibiting, preventing or reducing expression of an AMD associated gene. Preferably that AMD associated gene is one that is associated with wet AMD.
