  • Patent number: 11957749
    Abstract: The present invention relates to immunogenic compositions and combinations thereof which may find use in immunisation regimens for the treatment of chronic hepatitis B. An immunogenic composition comprises a replication-defective chimpanzee adenoviral (ChAd) vector comprising polynucleotides encoding HBs, HBc human invariant chain (hIi) fused to the HBc. Another immunogenic composition comprises a Modified Vaccinia Virus Ankara (MVA) vector comprising polynucleotides encoding HBs and HBc. Another immunogenic composition comprises recombinant HBs, C-terminal truncated recombinant HBc and an adjuvant containing MPL and QS-21.

  • Publication number: 20220339281
    Abstract: There is provided a method of treating chronic hepatitis B infection (CHB) and/or chronic hepatitis D infection (CHD) in a human, comprising the steps of: a) administering to the human a composition comprising an antisense oligonucleotide (ASO) 10 to 30 nucleosides in length, targeted to a HBV nucleic acid (an HBV ASO); b) administering to the human a composition comprising a replication-defective chimpanzee adenoviral (ChAd) vector comprising a polynucleotide encoding a hepatitis B surface antigen (HBs) and a nucleic acid encoding a hepatitis B virus core antigen (HBc); c) administering to the human a composition comprising a Modified Vaccinia Virus Ankara (MVA) vector comprising a polynucleotide encoding a hepatitis B surface antigen (HBs) and a nucleic acid encoding a hepatitis B virus core antigen (HBc); and d) administering to the human a composition comprising a recombinant hepatitis B surface antigen (HBs), recombinant hepatitis B virus core antigen (HBc) and an adjuvant.
