Abstract

The present invention provides compositions comprising emulsion adjuvant and one or more active agents or substances formulated for infusion or injection into a subject (e.g., using a syringe and needle), as well as methods of formulating and using the same (e.g., as an injectable medicinal composition (e.g., a vaccine)). The emulsion adjuvant of an immunogenic composition of the invention in its preferred form comprises a cationic lipid containing a polar head group and a hydrophobic component (e.g., a dual chain hydrophobic group (e.g., the cationic surfactant dioctadecyl dimethyl ammonium chloride (DODAC) and dioctadecyl dimethyl ammonium bromine (DODAB))). Compositions of the invention comprising emulsion adjuvant and one or more active agents or substances formulated for administration via injection to a subject find use in treatment and/or prevention of infectious disease, cancer and/or allergy.

Claims (10)

1. An immunogenic composition formulated for administration via injection comprising:

an oil in water emulsion comprising dioctadecyldimethylammonium chloride (DODAC), a non-ionic surfactant, an organic solvent, oil, and water, wherein the surfactant blend ratio of DODAC to non-ionic surfactant is 1:6, and

an antigen;

wherein the antigen is an inactivated microbial pathogen, an isolated protein from a microbial pathogen, and/or a recombinant protein from a microbial pathogen; and

wherein the immunogenic composition produces a cell mediated immune response comprising elevated levels of IFN-γ and detectable, antigen-specific neutralizing antibody titers when administered via injection and fails to produce a cell mediated immune response comprising elevated levels of IFN-γ and detectable, antigen-specific neutralizing antibody titers when administered intranasally via the nasal mucosa.
