Abstract: The present disclosure relates to the targeted delivery of defined active agents and/or immunomodulatory agents to lymph nodes or lipoid cells in a lymphatic tissue. More particularly, the invention provides methods for targeted delivery of a defined active agent or immunomodulatory agent to lymph nodes or lymphoid cells in a lymphatic tissue, comprising administering to a subject in need thereof a composition comprising the active agent or immunomodulatory agent, one or more lipid-based structures, and a hydrophobic carrier.

Abstract: The invention provides lipid A mimics in which one or both of the sugar residues of a natural lipid A disaccharide backbone has been replaced with an aromatic group. These lipid A mimics may further differ from a natural lipid A molecule with respect to other structural characteristics, such as, a different number of phosphate groups present, changes in the number, structure and location of lipid chains and/or changes in the spacing and linkage of the sugar residues (or their aromatic replacements). The lipid A mimics may be lipid A agonists and as such may be useful as immunostimulatory agents in inducing or patenting an antibody and/or cell-mediated immune response, or may be lipid A antagonists and as such may be useful in treating or preventing a lipopolysaccharide (LPS)/lipid A-mediated disease or disorder. Also provided are methods for preparing the lipid A mimics.

Abstract: The present disclosure relates to methods for preparing a dried preparation comprising lipids and therapeutic agents whereby the therapeutic agents are incorporated both before and after sizing of lipid vesicle particles to a mean particle size of ?120 nm and a polydispersity index (PDI) of ?0.1. The present application also provides stable, water-free pharmaceutical compositions comprising one or more lipid-based structures having a single layer lipid assembly, at least two therapeutic agents, and a hydrophobic carrier, as well as methods of treatment, uses and kits relating thereto, such as for example for inducing an antibody and/or CTL immune response.
