Abstract

The present invention relates to compounds, compositions, and methods for the study, diagnosis, and treatment of traits, diseases and conditions that respond to the modulation of hepatitis C virus (HCV) gene expression and/or activity. The present invention is also directed to compounds, compositions, and methods relating to traits, diseases and conditions that respond to the modulation of expression and/or activity of genes involved in hepatitis C virus (HCV) gene expression pathways or other cellular processes that mediate the maintenance or development of such traits, diseases and conditions. Specifically, the invention relates to double stranded nucleic acid molecules capable of mediating or that mediate RNA interference (RNAi) against hepatitis C virus (HCV) gene expression, including cocktails of such small nucleic acid molecules and lipid nanoparticle (LNP) formulations of such small nucleic acid molecules.

Claims (13)

1. A composition comprising a first double stranded nucleic acid molecule and a second double stranded nucleic acid molecule, each having a first strand and a second strand that are independently 15 to 30 nucleotides in length and wherein at least 15 nucleotides of the first strand are complementary to the second strand, and wherein at least 15 nucleotides of the second strand of said first double stranded nucleic acid molecule are complementary to a first HCV sequence that is SEQ ID NO: 1444 and at least 15 nucleotides of the second strand of said second double stranded nucleic acid molecule are complementary to a second HCV sequence that is SEQ ID NO: 1417.

2. The composition of claim 1 , further comprising a cationic lipid, a neutral lipid, and a polyethyleneglycol-conjugate.

3. The composition of claim 1 , further comprising a cationic lipid, a neutral lipid, a polyethyleneglycol-conjugate, and a cholesterol.

4. The composition of claim 1 , further comprising a cationic lipid, a neutral lipid, a polyethyleneglycol-conjugate, a cholesterol, and a surfactant.

5. The composition of any one of claims 2 to 4 , wherein said cationic lipid is CLinDMA.

6. The composition of any one of claims 2 to 4 , wherein said neutral lipid is DSPC.

7. The composition of any one of claims 2 to 4 , wherein said polyethyleneglycol-conjugate is a PEG-dimyristoyl glycerol.

8. The composition of claim 7 , wherein said PEG is 2KPEG.

9. The composition of claim 4 , wherein said surfactant is linoleyl alcohol.

10. The composition of claim 4 , wherein said cationic lipid is CLinDMA, said neutral lipid is DSPC, said polyethylene glycol conjugate is 2KPEG-DMG, said cholesterol is cholesterol, and said surfactant is linoleyl alcohol.

11. The composition of claim 10 , wherein said CLinDMA, said DSPC, said 2KPEG-DMG, said cholesterol, and said linoleyl alcohol are present in molar ratio of 43:38:10:2:7 respectively.

12. The composition of claim 1 , wherein said first strand and said second strand of said first double stranded nucleic acid molecule comprise SEQ ID NOs: 1796 and 2102, respectively, and said first strand and said second strand of said second double stranded nucleic acid molecule comprise SEQ ID NOs: 1677 and 2103, respectively.

13. A composition comprising the composition of any one of claims 1 - 4 in a pharmaceutically acceptable carrier or diluent.
