US Classification:

424450000, 435458000

Abstract:

A method for administering a therapeutic or diagnostic agent to a subject is described. The method includes providing a suspension of liposomes comprised of one or more of vesicle-forming lipids selected from (i) a vesicle-forming lipid derivatized with a hydrophilic polymer and (ii) a neutral lipopolymer, said liposomes being associated with said therapeutic or diagnostic agent, forming an aerosol of said liposome suspension; and administering the aerosol to the subject by inhalation. The liposome formulation delivers intact liposomal particles to the respiratory tract of said subject to form a depot of therapeutic agent therein with no observable provocation of an immune response, as measured by neutrophil or macrophage cell count in the lung after administration.

Abstract:

An immunoliposome composition comprised of liposomes bearing a ligand for targeting to cells expressing a growth factor receptor, such as HER2, is described. Binding of the immunoliposome to HER2-expressing cells results in internalization of the immunoliposome for cytoplasmic delivery of an entrapped drug.
