    摘要: First generation adenoviral vectors and associated recombinant adenovirus-based HIV vaccines which show enhanced stability and growth properties and greater cellular-mediated immunity are described within this specification. These adenoviral vectors are utilized to generate and produce through cell culture various adenoviral-based HIV-1 vaccines which contain HIV-1 gag, HIV-1 pol and/or HIV-1 nef polynucleotide pharmaceutical products, and biologically relevant modifications thereof. These adenovirus vaccines, when directly introduced into living vertebrate tissue, preferably a mammalian host such as a human or a non-human mammal of commercial or domestic veterinary importance, express the HIV1-Gag, Pol and/or Nef protein or biologically modification thereof, inducing a cellular immune response which specifically recognizes HIV-1. The exemplified polynucleotides of the present invention are synthetic DNA molecules encoding HIV-1 Gag, encoding codon optimized HIV-1 Pol, derivatives of optimized HIV-1 Pol (including constructs wherein protease, reverse transcriptase, RNAse H and integrase activity of HIV-1 Pol is inactivated), HIV-1 Nef and derivatives of optimized HIV-1 Nef, including nef mutants which effect wild type characteristics of Nef, such as myristylation and down regulation of host CD4. The adenoviral vaccines of the present invention, when administered alone or in a combined modality regime, will offer a prophylactic advantage to previously uninfected individuals and/or provide a therapeutic effect by reducing viral load levels within an infected individual, thus prolonging the asymptomatic phase of HIV-1 infection.

    摘要: An efficient means of inducing an immune response against human immunodeficiency virus (HIV) utilizing specific prime-boost regimes is disclosed. The specific prime-boost regimes employ a heterologous prime-boost protocol employing recombinant adenoviral vectors of alternative and distinct serotypes comprising exogenous genetic material encoding a common HIV antigen. Vaccines administered into living vertebrate tissue in accordance with the disclosed regimes, preferably a mammalian host, such as a human or a non-human mammal of commercial or domestic veterinary importance, express the HIV-1 antigen (e.g., Gag), inducing a cellular immune response which specifically recognizes HIV-1. It is believed that the disclosed prime/boost regime will offer a prophylactic advantage to previously uninfected individuals and/or provide a therapeutic effect by reducing viral load levels within an infected individual, thus prolonging the asymptomatic phase of HIV-1 infection.

    摘要: Applicants disclose herein novel methods, vectors, and vector compositions for improving the efficiency of adenoviral vectors in the delivery and expression of heterologous nucleic acid encoding a polypeptide(s) (e.g, a protein or antigen) of interest. Adenoviral infection is quite common in the general population, and a large percentage of people have neutralizing antibodies to the more prevalent adenoviral serotypes. Such pre-existing anti-adenoviral immunity can dampen or possibly abrogate the effectiveness of this virus for the delivery and expression of heterologous proteins or antigens. The method taught herein functions to offset pre-existing immunity through the delivery of the protein or antigen by a cocktail of at least two adenoviral serotypes. Utilizing a composition of at least two adenoviral serotypes in this manner has been found to increase the effectiveness of adenoviral administration. Adenoviral vectors of utility in the elicitation of an immune response against Human Immunodeficiency Virus (“HIV”) are also disclosed.

    摘要: The instant invention provides for novel lipid nanoparticle (LNP) formulations, containing cationic lipids, for use as vaccine adjuvants and/or as antigen delivery systems. It is an object of the instant invention to provide LNP formulations that demonstrate enhancements in humoral and cellular immunogenicity of vaccine antigens, particularly subunit vaccine antigens, when utilized alone or in combination with immunostimulatory agents (e.g. small molecule or oligonucleotide TLR agonists). The instant invention further identifies physical and chemical properties of the LNP formulations that can be manipulated to enhance antigen efficiency and adjuvant tolerability in vivo.
