20140356399 | COMPOSITIONS AND METHODS FOR TREATING VIRAL INFECTIONS - The present disclosure provides compositions and methods useful for treating viral infections. As described herein, the compositions and methods are based on the development of immunogenic compositions that include an inactivated virus in combination with a non-ionic surfactant vesicle (NISV). In certain embodiments at least a portion of the antigen present in the composition is physically associated with the NISV. In certain embodiments the compositions are lyophilized and subsequently rehydrated after a period of storage. In certain embodiments the rehydrated compositions exhibit greater potency as compared to otherwise equivalent compositions that lack the NISV. In certain embodiments the lyophilized compositions are stored at temperatures in excess of 8° C. prior to rehydration. In certain embodiments the rehydrated compositions exhibit greater potency as compared to otherwise equivalent compositions that lack the NISV and that were also stored at temperatures in excess of 8° C. prior to rehydration. In certain embodiments the antigen is taken from a licensed vaccine and the administered dose of antigen is less than the standard human dose for the licensed vaccine. | 12-04-2014 |
20130323280 | METHODS FOR PREPARING VESICLES AND FORMULATIONS PRODUCED THEREFROM - The present disclosure provides methods for preparing vesicles.

20120177683 | METHODS FOR PREPARING VESICLES AND FORMULATIONS PRODUCED THEREFROM - The present disclosure provides methods for preparing vesicles. In general, these methods include steps of providing a lyophilized lipid product and rehydrating the lyophilized lipid product with an aqueous solution comprising an antigen such that antigen-containing vesicles are formed. The lyophilized lipid product is prepared by dissolving vesicle-forming lipids in a polar-protic water-miscible organic solvent to produce a lipid solution and then lyophilizing the lipid solution. The present disclosure also provides antigen-containing vesicle formulations prepared using these methods. The present disclosure also provides kits that include a lyophilized lipid product in a first container and an aqueous solution comprising an antigen in a second container. | 07-12-2012 |

20110177163 | COMPOSITIONS AND METHODS FOR TREATING HEPATITIS A - The present application provides compositions and methods useful for treating hepatitis A. In particular, while hepatitis A vaccines are currently limited to parenteral administration routes (i.e., intramuscular injection), we have identified compositions that induce a protective response when administered orally. | 07-21-2011 |
20110097418 | COMPOSITIONS AND METHODS FOR TREATING INFLUENZA - The present application provides compositions and methods useful for treating influenza. As described herein, the compositions and methods are based on the development of peptides and peptide combinations which exhibit immunogenic properties against influenza. In some embodiments, the peptide combinations induce a protective response against multiple strains of influenza, e.g., seasonal strains of influenza or even the new pandemic influenza A (H1N1) virus of swine origin. | 04-28-2011 |
20110020381 | INFLUENZA VACCINE FORMULATION - Peptide-based anti-influenza formulations against influenza are disclosed. The peptides are derived from influenza-based epitopes.

20100121029 | ANTI-HIV IMMUNOGENIC FORMULATION AND PROCESS FOR PREPARATION THEREOF - A process is disclosed for preparation of a immunogenic peptide mixture in a single synthesis. The peptide mixture collectively represents the in vivo variability seen in immunogenic epitopes from an HIV pathogen. The mixture is termed a hypervariable epitope construct (HEC). Immunization with a HEC evokes broadly reactive immunity against divergent strains of a pathogen upon which the HEC is based. | 05-13-2010 |

The vaccine comprises an combination of immunogenic peptide mixtures, which mixtures may be prepared in a single synthesis. The composition collectively represents the in vivo variability seen in immunogenic epitopes from highly variable regions of HIV. Immunization with the vaccine elicits broadly reactive immunity (CTL and T helper cell responses) against the divergent strains of HIV upon which it is based. The vaccine may be formulated to target regionally distinct variability based on an HIV clade predominant in a geographical region. | 05-07-2009 |
