    摘要: 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 of between 1 kDa and 3 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 between 1 kDa and 3 kDa; and (ii) the aqueous core includes a RNA which encodes an immunogen. These liposomes are suitable for in vivo delivery of the RNA to a vertebrate cell and so they are useful as components in pharmaceutical compositions for immunising subjects against various diseases.

    摘要: The present invention relates to a novel method for producing formulations comprising a polynucleotide, block copolymer and cationic surfactant. The formulations produced by the current method are suitable for use in polynucleotide based medicaments. A suitable method of production disclosed herein additionally comprises cold filtering a mixture of a polynucleotide, block copolymer and cationic surfactant, thereby sterilizing the formulation. The method of the present invention also eliminates the need for thermal cycling of the formulation, thereby reducing the time and expense required to produce large quantities of a formulation during commercial manufacturing. The present invention also relates to novel cationic lipids.

    摘要: The present invention is directed to enhancing the immune response of a human in need of protection against IV infection by administering in vivo, into a tissue of the human, at least one polynucleotide comprising one or more regions of nucleic acid encoding an IV protein or a fragment, a variant, or a derivative thereof. The present invention is further directed to enhancing the immune response of a human in need of protection against IV infection by administering, in vivo, into a tissue of the human, at least one IV protein or a fragment, a variant, or derivative thereof. The IV protein can be, for example, in purified form or can be an inactivated IV, such as those present in inactivated IV vaccines. The polynucleotide is incorporated into the cells of the human in vivo, and an immunologically effective amount of an immunogenic epitope of an IV, or a fragment, variant, or derivative thereof is produced in vivo. The IV protein (in purified form or in the form of an inactivated IV vaccine) is also administered in an immunologically effective amount.
