  • Publication number: 20170002356
    Abstract: This invention is directed to a RNA interference (RNAi) agent and the use of that RNAi agent to treat hepatitis B infection in individuals, as well as pharmaceutical compositions containing the RNAi agents of the invention. The RNAi agents, or constructs for expressing them are utilised to inhibit expression of at least one Hepatitis B virus (HBV) gene, where the agent comprises an effector sequence complementary to or substantially complementary to a predicted sequence transcribed from a target region. In some forms of the invention, the agent has more than one effector sequence. Multiple effectors may target the same region of an HBV gene, different (possibly overlapping) regions of the same gene and/or different HBV genes.

  • Publication number: 20160053267
    Abstract: This invention relates to interfering RNA (iRNA) molecules and their applications, especially multi-targets iRNA molecules and their applications. The said multi-targets iRNA molecules comprised of a sense strand annealed onto at least one antisense strand, each strand is at least 30 nucleotides in length, the sense or antisense strand has at least two segments, which can target at least two RNAs of different genes, or can target at least two portions of an RNA, and wherein the iRNA does not induce an interferon-response when transfected into a cell. The iRNA molecule can interfere with the translation procedure post-transcription, and the target gene is inhibited or blocked, the iRNA does not induce an interferon-response in vivo.
