  • Patent number: 9573811
    Abstract: The present invention relates to methods for preparing amorphous aluminum hydroxyphosphate. An aluminum salt and a phosphate solution are co-mixed at a constant ratio in the presence of a buffer. Preferably, an excess of the phosphate solution is used to act as a buffer. Due to the presence of a buffer, the pH is maintained constant during reaction (after initial rapid equilibration) without active adjustment. The methods are particularly applicable for the large scale manufacturing of aluminum phosphate adjuvant. Aluminum phosphate is used as an adjuvant in vaccine formulations, particularly those including a protein or saccharide antigen.

  • Patent number: 8192746
    Abstract: The present invention provides a multivalent immunogenic composition having 15 distinct polysaccharide-protein conjugates. Each conjugate consists of a capsular polysaccharide prepared from a different serotype of Streptococcus pneumoniae (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 22F, 23F or 33F) conjugated to a carrier protein, preferably CRM197. The immunogenic composition, preferably formulated as a vaccine on an aluminum -based adjuvant, provides broad coverage against pneumococcal disease, particularly in infants and young children.

  • Patent number: 6339069
    Abstract: Peptide-lipid conjugates are incorporated into liposomes so as to selectively destabilize the liposomes in the vicinity of target peptidase-secreting cells, and hence, to deliver the liposomes to the vicinity of the target cells, or directly into the cells. The liposomes can thus be used to treat mammals for diseases, disorders or conditions, e.g., tumors, microbial infection and inflammations, characterized by the occurrence of peptidase-secreting cells.

  • Patent number: 6086851
    Abstract: This invention provides a composition containing a sized liposome comprising a lipid and an inducer; the sized liposome has a diameter of at most about 1 micron and the inducer is present in an amount effective to induce interdigitation-fusion of the sized liposome. Also provided herein are interdigitation-fusion liposomes and gels, and methods of making the same.

  • Patent number: 5662930
    Abstract: Provided herein is a method of administering a liposome composition to an animal, the method involving adminstering to the animal a liposome composition containing an adverse physiological reaction-reducing effective amount of a liposome which has, in addition to a bioactive agent, a lipid bilayer containing a lipid and a surface agent-modified molecule. An adverse physiological reaction which may be experienced by the animal upon administration of a liposome composition is reduced by way of the presence of the surface agent-modified molecule in the liposome's lipid bilayer.
