Papillomavirus vaccine compositions
View Patent ↗The present invention relates to pharmaceutical compositions comprising virus-like particles (VLPs) of HPV, said VLPs adsorbed to an aluminum adjuvant, and an ISCOM-type adjuvant comprising a saponin, cholesterol, and a phospholipid. In preferred embodiments, the aluminum adjuvant comprises amorphous aluminum hydroxyphosphate sulfate. Another aspect of the invention provides multi-dose HPV vaccine formulations comprising HPV VLPs and an antimicrobial preservative selected from the group consisting of: m-cresol, phenol and benzyl alcohol. Also provided are methods of using the disclosed pharmaceutical compositions and formulations to induce an immune response against HPV in a human patient and to prevent HPV infection.
1. A multi-dose HPV vaccine formulation comprising:
(a) HPV virus-like particles (VLPs) of at least one HPV type; said HPV VLPs comprised of recombinant L1 or recombinant L1+L2 protein of HPV;
(b) an aluminum adjuvant; and
(c) an antimicrobial preservative selected from the group consisting of: m-cresol, phenol, and benzyl alcohol, wherein said HPV VLPs are adsorbed onto said aluminum adjuvant.
2. The multi-dose HPV vaccine formulation of claim 1 , wherein the at least one type of HPV VLPs is selected from the group consisting of: HPV6, HPV11, HPV16, HPV18, HPV26, HPV31, HPV33, HPV35, HPV39, HPV45, HPV51, HPV52, HPV53, HPV55, HPV56, HPV58, HPV59, HPV66, HPV68, HPV73, and HPV82.
3. The multi-dose HPV vaccine formulation of claim 2 , comprising VLPs of HPV types 6, 11, 16, and 18.
4. The multi-dose HPV vaccine formulation of claim 2 , comprising VLPs of HPV types 31, 45, 52, and 58.
5. The multi-dose HPV vaccine formulation of claim 2 , comprising VLPs of HPV types 31, 35, 45, and 58.
6. The multi-dose HPV vaccine formulation of claim 4 , further comprising VLPs of an additional HPV type selected from the group consisting of: HPV26, HPV33, HPV35, HPV39, HPV51, HPV53, HPV55, HPV56, HPV59, HPV66, HPV68, HPV73, and HPV82.
7. The multi-dose HPV vaccine formulation of claim 1 , wherein the aluminum adjuvant is selected from the group consisting of: aluminum hydroxyphosphate (AlPO 4 ), amorphous aluminum hydroxyphosphate sulfate (AAHS), and aluminum hydroxide (Al(OH) 3 ).
8. The multi-dose HPV vaccine formulation of claim 7 , wherein the aluminum adjuvant comprises AlPO 4 or AAHS, which adjuvant comprises phosphate and aluminum present in a molar ratio of about 0.1 to about 1.1 phosphate (PO4) to aluminum (Al).
9. The multi-dose HPV vaccine formulation of claim 8 , wherein the aluminum adjuvant comprises phosphate and aluminum present in a molar ratio of about 0.2 to about 0.5 PO 04 /Al.
10. The multi-dose HPV vaccine formulation of claim 1 , wherein the antimicrobial preservative consists of m-cresol at a concentration of about 0.15 to about 0.31%, phenol at a concentration of about 0.25 to about 0.55%, or benzyl alcohol at a concentration of about 0.75 to about 12%.
11. The multi-dose vaccine formulation of claim 10 , wherein the antimicrobial preservative consists of m-cresol at a concentration of about 0.3%, phenol at a concentration of about 0.5% or benzyl alcohol at a concentration of about 0.9%.
12. The multi-dose vaccine formulation of claim 10 , wherein the antimicrobial preservative is m-cresol at a concentration of about 0.15 to about 0.31%.
13. The multi-dose vaccine formulation of claim 10 , wherein the antimicrobial preservative is phenol at a concentration of about 0.25 to about 0.55%.
14. The multi-dose vaccine formulation of claim 10 , wherein the antimicrobial preservative is benzyl alcohol at a concentration of about 0.75 to about 1.2%.
15. The multi-dose vaccine formulation of claim 10 , further comprising ISCOMATRIX® adjuvant.
16. The multi-dose vaccine formulation of claim 15 , wherein the ISCOMATRIX® adjuvant is present at a concentration between 20 μg/ml and 400 μg/ml.
