Abstract:
The invention discloses cancer vaccines comprising lipid-nucleic acid formulations in combination with one or more tumor-associated antigens which are capable of stimulating strong, Th-1 biased cellular immune responses to said tumor-associated antigens in vivo. It is further disclosed the subject cancer vaccines provide therapeutic efficacy in treating tumors in an animal.
Abstract:
This invention relates to improved liposomal camptothecin compositions and methods of manufacturing and using such compositions for treating neoplasia and for inhibiting angiogenesis.
Abstract:
Virosomes containing viral membrane fusion proteins and encapsulating therapeutic compounds are used to effectively deliver the therapeutic compounds to cytoplasm of mammalian host cells.
Abstract:
The present invention relates to compositions and methods for stimulating enhanced mucosal immune responses in vivo. Particularly, the present invention relates to lipid-nucleic acids ("LNA") formulations and methods of using thereof for stimulating enhanced mucosal immune responses in mammals. More particularly, the present invention relates to improved mucosal vaccines comprising target antigens associated with LNA formulations and methods of using thereof that stimulate antigen-specific mucosal immune responses in mammals.
Abstract:
The present invention provides lipid-based systemic delivery vehicles and method for selectively targeting an active agent to a specific tissue site. The methods include designing a lipid-based systemic delivery vehicle having a plurality of constitutent parts, and thereafter varying the amounts of each of the plurality of constituent parts to impart tissue selectivity. After tissue selectivity is imparted it is possible to selectively target an active agent to a specific tissue site.
Abstract:
It has now been discovered that oligonucleotides which tend to form multimeric aggregates have greater toxicity in the aggregate form than in monomeric form. Thus, the present invention provides therapeutic oligonucleotide compositions of reduced in vivo toxicity, and a method for making such compositions, as well as a method for administration of the therapeutic oligonucleotide, where the therapeutic oligonucleotide in one that tends to form multimeric aggregates. Compositions containing such aggregate-forming oligonucleotides are treated by heating, preferably no more than 24 hours prior to administration, or using chemical species such as mannitol which disrupt aggregates.
Abstract:
The present invention relates generally to the amphiphilic polyelectrolyte, poly(2-ethylacrylic acid) and covalently bonded lipids to generate Lipo-PEAA. These Lipo-PEAA are then used to make pH-sensitive liposomes which become unstable, permeable or fusogenic with certain pH changes. In addition, this invention generally describes methods for delivering therapeutic compounds and drugs to target cells by administering to a host the pH-sensitive liposomes of the present invention.
Abstract:
This invention relates to liposomes which are useful for the introduction of nucleic acids into cells. The liposomes of the present invention entrap a condensing agent-nucleic acid complex and are suitable for nucleic acid-transfer delivery vehicles in clinical use. In addition, methods of transfecting a cell with a nucleic acid using the liposomes of the present invention are also disclosed.
Abstract:
The present invention relates to methods for increasing the efficiency of transformation of cycling cells, the methods comprising synchronizing cells at a first stage of the cell cycle, and transforming the cells at a second stage of the cell cycle within about one cell cycle of the first stage with a genetically engineered nucleic acid that encodes a desired gene product. The invention further relates to cancer therapy and, in particular, to methods of efficiently transforming cancer cells with nucleic acids that encode gene products that inhibit the growth of cancer cells.
