Combination neisserial compositions
View Patent ↗Compositions comprising a first biological molecule from a Neisseria bacterium and a second biological molecule from a Neisseria bacterium. The term “biological molecule” includes proteins and nucleic acids. Preferred Neisseria species are N. meningitidis and N. gonorrhoeae.
1. A method of inducing a bactericidal immune response in an animal, comprising administering to the animal a composition which comprises
(a) an immunologically effective amount of a protein lacking an N-terminal cysteine at position 20 of SEQ ID NO: 3518 having the amino acid sequence of the mature form of SEQ ID NO: 3518; and
(b) an immunologically effective amount of an N. meningitidis protein comprising an amino acid sequence having at least 95% sequence identity to SEQ ID NO: 7645.
2. The method of claim 1 , wherein the composition consists essentially of (a) and (b).
3. The method according to claim 1 , wherein the protein lacking an N-terminal cysteine is a recombinant protein.
4. The method according to claim 1 , wherein the protein lacking an N-terminal cysteine is expressed as a fusion protein.
5. The method according to claim 1 , wherein the protein lacking the N-terminal cysteine is fused to a GST protein or a HIS-tag.
6. The method according to claim 1 , wherein the protein lacking an N-terminal cysteine and the N. meningitidis protein are from different strains of Neisseria meningitidis.
7. The method according to claim 1 , wherein the composition additionally comprises an adjuvant or buffer.
8. The method according to claim 1 , wherein the composition additionally comprises an adjuvant.
9. The method according to claim 1 , wherein the composition further comprises aluminum hydroxide.
10. The method according to claim 1 , wherein the composition further comprises a third Neisseria meningitidis biological molecule different than (a) and (b).
11. The method according to claim 1 , wherein the composition is administered by injection.
12. The method according to claim 1 , wherein the animal is a human patient.
13. A method of eliciting antibodies against N. meningitidis bacteria in an animal, comprising administering to the animal a composition which comprises
(a) an immunologically effective amount of a protein lacking an N-terminal cysteine at position 20 of SEQ ID NO: 3518 having the amino acid sequence of the mature form of SEQ ID NO: 3518; and
(b) an immunologically effective amount of an N. meningitidis protein comprising an amino acid sequence having at least 95% sequence identity to SEQ ID NO: 7645.
14. The method according to claim 13 , wherein the composition consists essentially of (a) and (b).
15. The method according to claim 13 , wherein the protein lacking an N-terminal cysteine is expressed as a fusion protein.
16. The method according to claim 13 , wherein the protein lacking an N-terminal cysteine and the N. meningitidis protein are from different strains of Neisseria meningitidis.
17. The method according to claim 13 , wherein the composition additionally comprises an adjuvant or buffer.
18. The method according to claim 13 , wherein the composition further comprises aluminum hydroxide.
19. The method according to claim 13 , wherein the composition further comprises a third Neisseria meningitidis biological molecule different than (a) and (b).
20. The method according to claim 13 , wherein the composition is administered by injection.
21. The method according to claim 13 , wherein the animal is a human patient.
22. A method of eliciting antibodies against N. meningitidis bacteria in an animal, comprising administering by injection to the animal a composition which comprises
(a) an immunologically effective amount of a protein lacking an N-terminal cysteine at position 20 of SEQ ID NO: 3518 having the amino acid sequence of the mature form of SEQ ID NO: 3518; and
(b) an immunologically effective amount of an N. meningitidis protein comprising an amino acid sequence having at least 95% sequence identity to SEQ ID NO: 7645,
(c) a buffer, and
(d) aluminum hydroxide,
wherein the protein lacking an N-terminal cysteine and the N. meningitidis protein are from different strains of Neisseria meningitidis , thereby eliciting antibodies against Neisseria meningitidis bacteria in the animal.
23. The method of claim 22 , wherein the immune response induced by the protein lacking an N-terminal cysteine is bactericidal against at least three strains of Neisseria meningitidis in the animal, thereby eliciting bactericidal antibodies against at least three strains of Neisseria meningitidis in the animal.
24. The method according to claim 22 , wherein the composition consists essentially of (a) and (b).
