The present disclosure provides methods, uses and compositions and kits for use in inducing an antibody immune response in a human subject. The methods and uses involve administering parenterally a low dose volume of a composition comprising an antigen comprising a B-cell epitope, an amphipathic compound, and a hydrophobic carrier, wherein the low dose volume of the composition is less than 100 μl and induces an antibody immune response to the B-cell epitope in the human subject.

Methods of using low dose volume B-cell epitope compositions for inducing an antibody immune response in human subjects

The invention provides a composition comprising: an antigen; liposomes; a polyI:C polynucleotide; and a carrier comprising a continuous phase of a hydrophobic substance. Methods for making and using the compositions are also provided.

Compositions comprising liposomes, an antigen, a polynucleotide and a carrier comprising a continuous phase of a hydrophobic substance

The present disclosure provides methods, uses and compositions and kits for use in inducing an antibody immune response in a human subject. The methods and uses involve administering parenterally a low dose volume of a composition comprising an antigen comprising a B-cell epitope, an amphipathic compound, and a hydrophobic carrier, wherein the low dose volume of the composition is less than 100 &#x3bc;l and induces an antibody immune response to the B-cell epitope in the human subject.

The invention provides compositions comprising a carrier comprising a continuous phase of a hydrophobic substance, liposomes, and a polynucleotide, and methods for using such compositions for delivering a polynucleotide to a subject.

Use of liposomes in a carrier comprising a continuous hydrophobic phase for delivery of polynucleotides in vivo

The present disclosure provides adjuvanting systems comprising: (a) a polyI:C polynucleotide adjuvant; (b) a lipid-based adjuvant; (c) an amphipathic compound; and (d) a hydrophobic carrier. Also provided are vaccine compositions that are water-free or substantially free of water, which comprise the same components together with one or more antigens. The disclosure also provides uses for such compositions in inducing an antibody (humoral) and/or cell-mediated immune response and methods for their use in the treatment of a disease, disorder or ailment ameliorated by an antibody and/or cell-mediated immune response.

Adjuvanting systems and water-free vaccine compositions comprising a polyI:C polynucleotide adjuvant and a lipid-based adjuvant

The invention provides compositions comprising liposomes, an antigen capable of inducing a humoral immune response, a carrier comprising a continuous phase of a hydrophobic substance, and an adjuvant that activates or increases the activity of TLR2. The invention also provides uses for such compositions in inducing a humoral response and methods for their use in the treatment of a disease, disorder or ailment ameliorated by a humoral immune response.

Liposome compositions comprising PAM2Cys or PAM3Cys adjuvant and methods for inducing a humoral immune response

The invention provides lipid A mimics in which one or both of the sugar residues of a natural lipid A disaccharide backbone has been replaced with an aromatic group. These lipid A mimics may further differ from a natural lipid A molecule with respect to other structural characteristics, such as, a different number of phosphate groups present, changes in the number, structure and location of lipid chains and/or changes in the spacing and linkage of the sugar residues (or their aromatic replacements). The lipid A mimics may be lipid A agonists and as such may be useful as immunostimulatory agents in inducing or patenting an antibody and/or cell-mediated immune response, or may be lipid A antagonists and as such may be useful in treating or preventing a lipopolysaccharide (LPS)/lipid A-mediated disease or disorder. Also provided are methods for preparing the lipid A mimics.

Lipid A mimics, methods of preparation, and uses thereof

The present invention provides methods for improving the efficacy of a vaccine in the treatment of cancer. The methods of the invention comprise the administration of at least two doses of an agent that interferes with DNA replication prior to vaccination with a survivin vaccine. Also provided are compositions for use in the methods of the invention.

Method for improving the efficacy of a survivin vaccine in the treatment of cancer

The invention compositions comprising a continuous hydrophobic phase and liposomes as a vehicle for delivery of an antigen capable of inducing a cytotoxic T lymphocyte (CTL) response and methods for their use in the treatment of cancer.
