  • Publication number: 20240033376
    Abstract: The present invention provides compositions, systems, kits, and methods for expression of one or more biomolecules in a subject, human or non-human mammal, (e.g., at therapeutic levels for the extended periods of time required to produce therapeutic effects). In certain embodiments, compositions, systems, kits, and methods are provided that comprise a first composition comprising polycationic structures (e.g., empty cationic liposomes, cationic micelles, cationic emulsions, or cationic polymers) and a second composition comprising expression vectors (e.g., non-viral expression vectors not associated with liposomes or other carriers) encoding one or more biomolecules of interest.

  • Patent number: 10905777
    Abstract: The present invention provides compositions, systems, kits, and methods for generating expression of one or more proteins and/or biologically active nucleic acid molecules in a subject (e.g., at therapeutic levels for extended periods required to produce therapeutic effects). In certain embodiments, systems and kits are provided that comprise a first composition comprising a first amount of polycationic structures, and a second composition comprising a therapeutically effective amount of expression vectors (e.g., non-viral expression vectors not associated with liposomes) that are CpG-free or CpG-reduced, where the expression vectors comprise a first nucleic acid sequence encoding: i) a first therapeutic protein or proteins, and/or ii) a first biologically active nucleic acid molecule or molecules.
