  • Publication number: 20200323896
    Abstract: RNA encoding an immunogen is co-delivered to non-immune cells at the site of delivery and also to immune cells which infiltrate the site of delivery. The responses of these two cell types to the same delivered RNA lead to two different effects, which interact to produce a strong immune response against the immunogen. The non-immune cells translate the RNA and express the immunogen. Infiltrating immune cells respond to the RNA by expressing type I interferons and pro-inflammatory cytokines which produce a local adjuvant effect which acts on the immunogen-expressing non-immune cells to upregulate major histocompatibility complex expression, thereby increasing presentation of the translated protein to T cells. The effects on the immune and non-immune cells can be achieved by a single delivery of a single RNA e.g. by a single injection.

  • Patent number: 10639361
    Abstract: The present invention is directed to methods of preventing reactivation of active and latent M. tuberculosis infections by administering a pharmaceutical composition comprising a nucleic acid encoding a Mtb72f fusion protein, or a Mtb72f fusion protein or an immunogenic fragment thereof, for example together with an adjuvant. The Mtb72f nucleic acid or fusion protein can be administered with one or more chemotherapeutic agents effective against a M. tuberculosis infection. The methods also provide for shortening the time course of a chemotherapeutic regimen against a M. tuberculosis infection.

  • Publication number: 20200113830
    Abstract: Nucleic acid immunisation is achieved by delivering RNA encapsulated within a PEGylated liposome. The RNA encodes an immunogen of interest. The PEG has an average molecular mass above 3 kDa but less than 11 kDa. Thus the invention provides a liposome having a lipid bilayer encapsulating an aqueous core, wherein: (i) the lipid bilayer comprises at least one lipid which includes a polyethylene glycol moiety, such that polyethylene glycol is present on the liposome's exterior, wherein the average molecular mass of the polyethylene glycol is above 3 kDa but less than 11 kDa; and (ii) the aqueous core includes a RNA which encodes an immunogen.
