Provided are formulations, compositions and methods for delivering biological moieties such as modified nucleic acids into cells to modulate protein expression. Such compositions and methods include the delivery of biological moieties, and are useful for production of proteins.
1. A method of producing a polypeptide of interest in a cell in a subject in need thereof, comprising administering to the subject a pharmaceutical composition comprising a modified messenger RNA (mmRNA), in a lipid nanoparticle (LNP) formulation, said lipid nanoparticle formulation comprising a lip
1. A method of producing a polypeptide of interest in a cell in a subject in need thereof, comprising administering to the subject a pharmaceutical composition comprising a modified messenger RNA (mmRNA), in a lipid nanoparticle (LNP) formulation, said lipid nanoparticle formulation comprising a lipid selected from the group consisting of DLin-DMA, DLin-K-DMA, DLin-KC2-DMA, DLin-MC3-DMA, 98N12-5, and C12-200; a cholesterol; and a PEG-lipid; such that the mmRNA is introduced into the cell, wherein the mmRNA comprises a translatable region encoding the polypeptide of interest and comprises the modified nucleoside 1-methyl-pseudouridine, and wherein the pharmaceutical composition comprises an effective amount of the mmRNA providing for increased polypeptide production and substantially reduced innate immune response in the cell, as compared to a composition comprising a corresponding unmodified mRNA. 2. The method of claim 1, wherein the mmRNA comprises the modified nucleoside 1-methyl-pseudouridine in combination with 5-methyl-cytidine. 3. The method of claim 2, wherein the mmRNA comprises at least about 95% 1-methyl-pseudouridine in place of uracils and at least about 95% 5-methyl-cytidine in place of cytosines. 4. The method of claim 2, wherein the mmRNA comprises about 100% 1-methyl-pseudouridine in place of uracils and about 100% 5-methyl-cytidine in place of cytosines. 5. The method of claim 1, wherein the innate immune response is reduced from 80% to 99.9% as compared to the immune response induced by a corresponding unmodified mRNA. 6. The method of claim 1, wherein the mmRNA reduces the expression or activity level of a Type 1 interferon compared to the corresponding unmodified mRNA. 7. The method of claim 1, wherein the mmRNA and LNP are formulated at a total lipid to mmRNA weight ratio of between 10:1 and 30:1. 8. The method of claim 1, wherein the pharmaceutical composition is administered by an intravenous route. 9. The method of claim P, wherein the pharmaceutical composition is administered by an intramuscular route. 10. The method of claim 1, wherein the pharmaceutical composition is administered by a subcutaneous route. 11. The method of claim 1, wherein the subject is a human. 12. The method of claim 1, where the pharmaceutical composition is administered at a total dose of about 0.1 mg/kg to about 40 mg/kg. 13. The method of claim 1, wherein administration occurs on a schedule selected from the group consisting of three times a day, twice a day, once a day, every other day, every third day, weekly, biweekly, every three weeks, every four weeks, and monthly. 14. The method of claim 12, wherein the total dose is administered by multiple administrations. 15. The method of claim 14, wherein the multiple administrations occur on a schedule selected from the group consisting of three times a day, twice a day, once a day, every other day, every third day, weekly, biweekly, every three weeks, every four weeks, and monthly. 16. The method of claim 1, wherein the increased polypeptide production is observed in a tissue or bodily fluid within 8 hours. 17. The method of claim 1, wherein the increased polypeptide production is observed in a tissue or bodily fluid within 2 hours.
