Abstract

The present invention is directed to an artificial nucleic acid and to polypeptides suitable for use in treatment or prophylaxis of an infection with Norovirus or a disorder related to such an infection. In particular, the present invention concerns a Norovirus vaccine. The present invention is directed to an artificial nucleic acid, polypeptides, compositions and vaccines comprising the artificial nucleic acid or the polypeptides. The invention further concerns a method of treating or preventing a disorder or a disease, first and second medical uses of the artificial nucleic acid, polypeptides, compositions and vaccines. Further, the invention is directed to a kit, particularly to a kit of parts, comprising the artificial nucleic acid, polypeptides, compositions and vaccines.

First claim

The invention claimed is:

1. A pharmaceutical composition comprising at least one artificial RNA molecule and at least three different RNA coding regions encoding three different Norovirus VP1 polypeptides, said coding regions each encoding a different GII.4 VP1 polypeptide and having at least 90% identity to the polypeptide coding sequence of SEQ ID NOs: 39713-39721 or 39726-39738, wherein the at least one artificial RNA molecule comprises at least one heterologous 5′ and/or 3′ untranslated region (UTR).

2. A method of treating or preventing a Norovirus infection in a subject comprising administering to the subject an effective amount of the pharmaceutical composition according to claim 1 , wherein the at least one artificial RNA molecule is formulated with a lipid nanoparticle (LNP).

3. The method of claim 2 , wherein the LNP comprises a cationic lipid, a phospholipid, cholesterol, and a PEG-lipid.

4. The method of claim 3 , wherein the LNP comprises a cationic lipid, DSPC, cholesterol, and PEG-lipid.

5. The method of claim 2 , wherein the at least one artificial RNA molecule is a mRNA.

6. The method of claim 5 , wherein the mRNA comprises a 5′ Cap and a poly(A) sequence of 10 to 200 adenosine nucleotides.

7. The method of claim 6 , wherein the mRNA comprises a heterologous 3′ untranslated region (UTR).

8. The method of claim 7 , wherein the mRNA comprises a heterologous 5′ UTR and a heterologous 3′ UTR.

9. The method of claim 2 , wherein composition comprises at least a second artificial RNA molecule encoding a Norovirus antigen.

10. The method of claim 9 , wherein the second artificial RNA molecule encodes a Norovirus VP1 antigen, wherein each of the VP1 antigens are from different strains of Norovirus.

11. The method of claim 10 , wherein the composition further comprises an artificial RNA molecule encoding a Norovirus VP1 antigen that is from a GI.1 strain of Norovirus.

12. The method of claim 9 , wherein the composition comprises at least four artificial RNA molecules each encoding a Norovirus VP1 antigen from a different norovirus strain.

13. The method of claim 2 , wherein at least one artificial RNA molecule comprises a sequence having at least 90% identity to the sequence of any one of SEQ ID NOs: 39713-39721 or 39726-39738.

14. The method of claim 2 , wherein at least one artificial RNA molecule comprises a coding region having at least 95% identity to the polypeptide coding sequence of any one of SEQ ID NOs: 39713-39721 or 39726-39738.

15. The method of claim 8 , wherein the composition is administered by intramuscular or intradermal injection.

16. The method of claim 15 , wherein the composition is administered by intramuscular injection.

17. The method of claim 16 , wherein anti-Norovirus neutralizing antibodies are produced in the subject.

18. The method of claim 17 , wherein the method produces anti-Norovirus neutralizing antibodies relative to Noroviruses having each of said at least three different Norovirus VP1 polypeptides.

19. The method of claim 16 , wherein the composition comprises at least three different RNA molecules encoding three different Norovirus VP1 polypeptides, each RNA molecule encoding a different GII.4 VP1 polypeptide and having at least 90% identity to the polypeptide coding sequence of SEQ ID NOs: 39713-39721 or 39726-39738.

20. The method of claim 19 , wherein the at least three different RNA molecules are mRNA molecules.

21. The pharmaceutical composition of claim 1 , wherein the composition comprises at least three different RNA molecules encoding three different Norovirus VP1 polypeptides, at least one of the different GII.4 VP1 polypeptides has at least 95% identity to the polypeptide coding sequence of SEQ ID NOs: 39713-39721 or 39726-39738.

22. The pharmaceutical composition of claim 1 , wherein the at least one artificial RNA molecule is formulated with a lipid nanoparticle (LNP).

23. The pharmaceutical composition of claim 22 , wherein the LNP comprises a cationic lipid, a phospholipid, cholesterol, and a PEG-lipid.

24. The pharmaceutical composition of claim 23 , wherein the LNP comprises a cationic lipid, DSPC, cholesterol, and PEG-lipid.

25. The pharmaceutical composition of claim 22 , wherein the composition comprises at least three artificial RNA molecules each encoding one of the at least three different Norovirus VP1 polypeptides.

26. The pharmaceutical composition of claim 25 , wherein the artificial RNA molecules are mRNA molecules.

27. The pharmaceutical composition of claim 25 , wherein the artificial RNA molecules each comprise a 5′ Cap and a poly(A) sequence of 10 to 200 adenosine nucleotides.

28. The pharmaceutical composition of claim 27 , wherein the artificial RNA molecules each comprise a heterologous 5′ UTR and a heterologous 3′ UTR.
