Dried composition of saponin in a liposomal formulation with a neutral lipid, a sterol, and a cryoprotectant
Composition are described, which are dried under reduced pressure from a liquid mixture comprising an adjuvant comprising a saponin (e.g., such as QS21) in a liposomal formulation wherein the liposomes contain a neutral lipid (e.g., such as a phosphatidylcholine) and a sterol (e.g., such as cholesterol), and, a cryoprotectant that is an amorphous sugar. The adjuvant may further comprises a TLR-4 agonist. The compositions may further comprising an antigen, such as an antigen derived from Plasmodium falciparum, Mycobacterium tuberculosis, HIV, Moraxella, ntHi or Varicella Zoster Virus. The cryoprotectant is an amorphous sugar or mixture of amorphous sugars, and preferably is a combination of at least two cryoprotectants selected from sucrose, trehalose and dextran. The compositions may further comprise a buffer and/or a surfactant..
