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.
