The present invention relates to pre-formulations comprising low viscosity, non-liquid crystalline, mixtures of: a) at least one neutral diacyl lipid and/or at least one tocopherol; b) at least one phospholipid; c) at least one biocompatible, oxygen containing, low viscosity organic solvent;
wherein at least one bioactive agent is dissolved or dispersed in the low viscosity mixture and wherein the pre-formulation forms, or is capable of forming, at least one liquid crystalline phase structure upon contact with an aqueous fluid. The preformulations are suitable for generating parenteral, non-parenteral and topical depot compositions for sustained release of active agents. The invention additionally relates to a method of delivery of an active agent comprising administration of a preformulation of the invention, a method of treatment comprising administration of a preformulation of the invention and the use of a preformulation of the invention in a method for the manufacture of a medicament.

The present invention relates to a composition comprising, preferably consisting of, (i) a single empty liposome, wherein said single empty liposome is selected from (a) an empty liposome consisting of sphingomyelin and cholesterol, wherein the amount of cholesterol is at least 20% (weight per weight); or (b) an empty liposome consisting of sphingomyelin; or (ii) a mixture of empty liposomes; wherein said mixture of empty liposomes comprises (a) a first empty liposome consisting of sphingomyelin and cholesterol, wherein the amount of cholesterol is at least 20% (weight per weight); and (b) a second empty liposome consisting of sphingomyelin; for use in a method of treating or preventing a viral infection in a mammal, preferably in a human.

The disclosure features immune cell delivery lipid nanoparticle (LNP) compositions that allow for enhanced delivery of agents, e.g., nucleic acids, such as therapeutic and/or prophylactic RNAs, to immune cells, in particular T cells, as well as B cells, dendritic cells and monocytes. The LNPs comprise an effective amount of an immune cell delivery potentiating lipid such that delivery of an agent by an immune cell delivery LNP is enhanced as compared to an LNP lacking the immune cell delivery potentiating agent. Methods of using the immune cell delivery LNPs for delivery of agents, e.g., nucleic acid delivery, for protein expression, for modulating immune cell activity and modulating immune responses are also disclosed.

The present disclosure provides compositions and methods useful for treating Glioblastoma Multiforme (GBM) which comprise virus-like particles (VLPs) comprising murine leukemia virus (MLV) core proteins and the human cytomegalovirus epitopes, gB and pp65, formulated with an adjuvant comprising a saponin and a TLR4 agonist.
