Lipid nanoparticle compositions and methods for mRNA delivery
View Patent ↗Disclosed herein are compositions and methods for modulating the production of a protein in a target cell. The compositions and methods disclosed herein are capable of ameliorating diseases associated with protein or enzyme deficiencies.
1. A method for delivery of messenger RNA (mRNA) for in vivo production of a secreted polypeptide, comprising administering, to a human, a composition comprising an mRNA that encodes the secreted polypeptide wherein the mRNA is encapsulated within a lipid nanoparticle, wherein the administering of the composition results in expression of the secreted polypeptide encoded by the mRNA that is detectable in serum at least 72 hours after administration, and wherein the lipid nanoparticle comprises one or more PEG-modified lipids.
2. The method of claim 1 , wherein the mRNA comprises a 5′ untranslated region.
3. The method of claim 2 , wherein the mRNA comprises a 3′ untranslated region.
4. The method of claim 3 , wherein the mRNA comprises a cap structure.
5. The method of claim 4 , wherein the mRNA comprises a poly A tail.
6. The method of claim 5 , wherein the lipid nanoparticle comprises one or more cationic lipids.
7. The method of claim 6 , wherein the lipid nanoparticle comprises one or more non-cationic lipids.
8. The method of claim 7 , wherein the mRNA is unmodified.
9. The method of claim 8 , wherein the composition is administered by intravenous injection.
10. The method of claim 8 , wherein the composition is administered by intramuscular injection.
11. The method of claim 8 , wherein the lipid nanoparticle has a size of less than about 100 nm.
12. The method of claim 8 , wherein the one or more PEG-modified lipids constitute from 0.1% to 20% of the total lipids by a molar ratio.
13. The method of claim 8 , wherein the composition is a reconstituted lyophilized composition.
14. The method of claim 7 , wherein the modification comprises a modified nucleotide.
15. The method of claim 14 , wherein the modified nucleotide is pseudouridine.
16. The method of claim 15 , wherein the composition is a reconstituted lyophilized composition.
17. The method of claim 15 , wherein the composition is administered by intravenous injection.
18. The method of claim 15 , wherein the composition is administered by intramuscular injection.
19. The method of claim 15 , wherein the lipid nanoparticle has a size of less than about 100 nm.
20. The method of claim 15 , wherein the one or more PEG-modified lipids constitute from 0.1% to 20% of the total lipids by a molar ratio.
21. The method of claim 5 , wherein the poly A tail comprises at least 90 nucleotides.
22. The method of claim 5 , wherein the poly A tail comprises at least 500 nucleotides.
