Methods of inducing an immune response against HIV-1 using recombinant envelopes with improved coverage
The present invention relates, in general, to human immunodeficiency virus-1 (HIV-1) particular, to a polyvalent vaccine for HIV-1 and to methods of making and using same.
1. A method of inducing an immune response in a subject comprising administering to the subject a composition comprising a recombinant HIV-1 polypeptide comprising: all the consecutive amino acids immediately after the signal peptide in an HIV-1 envelope AA 104.0 (amino acid positions 30-846 in SEQ ID NO: 1), all the consecutive amino acids immediately after the signal peptide in an HIV-1 envelope AA 107.0 (amino acid positions 30-861 in SEQ ID NO: 2), all the consecutive amino acids immediately after the signal peptide in an HIV-1 envelope AA 058.1 (amino acid positions 30-856 in SEQ ID NO: 3), or a combination thereof in an amount sufficient to effect induction, wherein each HIV-1 polypeptide is recombinantly produced.
2. A method of inducing an immune response in a subject comprising administering to the subject a composition comprising:
AA 104.0 gp120Delta N-terminus recombinant polypeptide comprising all the consecutive amino acids at amino acid positions 41-501 in SEQ ID NO:1,
AA 107.0 gp120Delta N-terminus recombinant polypeptide comprising all the consecutive amino acids at amino acid positions 41-509 in SEQ ID NO: 2, or
AA 058.1 gp120Delta N-terminus recombinant polypeptide comprising all the consecutive amino acids at amino acid positions 41-511 in SEQ ID NO:3 in an amount sufficient to effect induction, wherein each HIV-1 polypeptide is recombinantly produced.
3. A method of inducing an immune response in a subject comprising administering to the subject a composition comprising:
AA 104.0 gp120Delta N-terminus recombinant polypeptide, comprising all the consecutive amino acids at amino acid positions 41-501 in SEQ ID NO: 1,
AA 107.0 gp120Delta N-terminus recombinant polypeptide comprising all the consecutive amino acids at amino acid positions 41-509 in SEQ ID NO: 2, and
AA 058.1 gp120Delta N-terminus recombinant polypeptide comprising all the consecutive amino acids at amino acid positions 41-511 in SEQ ID NO:3, in an amount sufficient to effect induction, wherein each HIV-1 polypeptide is recombinantly produced.
4. A method of inducing an immune response in a subject comprising administering to the subject a composition comprising AA 104.0 gp120Delta N-terminus recombinant polypeptide, comprising all the consecutive amino acids at amino acid positions 41-501 in SEQ ID NO: 1 in an amount sufficient to effect induction, wherein the HIV-1 polypeptide is recombinantly produced.
5. The method of claim 1 or 2 - 4 further comprising administration of HIV-1 envelope B.63521 gp120D11 and A244 gp120 D11.
6. The method of claim 1 or 2 - 4 further comprising administration of HIV-1 envelope B.6240 gp120D11 and A244 gp120 D11.
7. The method of claim 1 or claim 2 - 4 , wherein the composition further comprises an adjuvant.
8. The method of claim 7 , wherein the adjuvant is a Toll-like receptor 4 agonist glucopyranosyl lipid adjuvant-stable emulsion (GLA/SE).
9. The method of claim 1 or 2 - 4 , wherein the composition is administered as a boost.
10. The method of claim 2 , wherein the composition is administered as a boost.
11. The method of claim 3 , wherein the composition is administered as a boost.
12. The method of claim 4 , wherein the composition is administered as a boost.
