Abstract

The present disclosure relates to compositions and methods for treating APOC3-related diseases such as: hypertriglyceridemia (e.g., Type V Hypertriglyceridemia), abnormal lipid metabolism, abnormal cholesterol metabolism, atherosclerosis, hyperlipidemia, diabetes, including Type 2 diabetes, obesity, cardiovascular disease, and coronary artery disease, among other disorders relating to abnormal metabolism or otherwise, using a therapeutically effective amount of a RNAi agent to APOC3.

First claim

We claim:

1. A double-stranded RNAi agent for inhibiting expression of an APOC3 gene in a cell, the RNAi anent comprising a first strand and a second strand, wherein said first strand is less than about 49 nucleotides in length and comprises at least 19 contiguous nucleotides differing by 0 or 1 nucleotides from the nucleotide sequence (5′ to 3′) AGCACUGAGAAUACUGUCC (SEQ ID NO: 132), wherein the second strand is substantially complementary to the first strand, wherein the first strand comprises at least one modified nucleotide or modified internucleoside linkage, wherein the 3′ end of the first strand and/or the second strand comprises a 3′ end cap, and wherein the 3′ end of the first and/or second strand terminates in a phosphate or modified internucleoside linker and further comprises, in 5′ to 3′ order: a spacer, a second phosphate or modified internucleoside linker, and a 3′ end cap.

2. The RNAi agent of claim 1 , wherein the spacer is selected from a sugar, alkyl, cycloalkyl, ribitol, 2′-deoxy-ribitol, diribitol, 2′-methoxyethoxy-ribitol, C3 [—(CH 2 ) 3 —], C4 [—(CH 2 ) 4 —], C5 [—(CH 2 ) 5 —], C6 [—(CH 2 ) 6 —], or 4-methoxybutane-1,3-diol.

3. The RNAi agent of claim 1 , wherein the RNAi agent is ligated to one or more diagnostic compound, reporter group, cross-linking agent, nuclease-resistance conferring moiety, natural or unusual nucleobase, lipophilic molecule, cholesterol, lipid, lectin, steroid, uvaol, hecigenin, diosgenin, terpene, triterpene, sarsasapogenin, Friedelin, epifriedelanol-derivatized lithocholic acid, vitamin, carbohydrate, dextran, pullulan, chitin, chitosan, synthetic carbohydrate, oligo lactate 15-mer, natural polymer, low- or medium-molecular weight polymer, inulin, cyclodextrin, hyaluronic acid, protein, protein-binding agent, integrin-targeting molecule, polycationic, peptide, polyamine, peptide mimic, and/or transferrin.

4. The RNAi agent of claim 1 , wherein the RNAi agent is ligated to one or more carbohydrates.

5. The RNAi agent of claim 1 , wherein the RNAi agent is ligated to one or more N-Acetylgalactosamines.

6. A double-stranded RNAi agent for inhibiting expression of an APOC3 gene in a cell, the RNAi agent comprising a first strand and a second strand, wherein said first strand is less than about 49 nucleotides in length and comprises at least 19 continuous nucleotides differing by 0 or 1 nucleotides from the nucleotide sequence (5′ to 3′) AGCACUGAGAAUACUGUCC (SEQ ID NO: 132), and wherein the second strand is substantially complementary to the first strand, wherein the RNAi agent is ligated to an N-Acctylgalactosamine-containing compound that comprises the following structure:

7. The RNAi agent of claim 1 , wherein the 3′ end cap comprises:

wherein,
X is (a) the 3′ end of a strand of a RNAi agent; (b) the 3′ end of a molecule comprising a strand of a RNAi agent, wherein the 3′ end of the strand terminates in a phosphate or modified internucleoside linker and further comprises in 5′ to 3′ order: a spacer, and a second phosphate or modified internucleoside linker; or (c) is a 3′ end of a molecule comprising: a strand of an APOC3 RNAi agent, wherein the 3′ end of the strand terminates in a phosphate or modified internucleoside linker and optionally further comprises, in 5′ to 3′ order: a spacer and a second phosphate or modified internucleoside linker;
q is 0, 1, or 2;
R 6 is phenyl which is unsubstituted or substituted with a group selected from benzoxy and 3,4-dihydroxybutyl;
R 7 is hydrogen or hydroxy-ethyl, wherein if R 7 is hydroxy-ethyl, the hydroxyl can be optionally functionalized as succinate or attached to a solid support;
R 8 is hydrogen or methoxy;
Y 1 is CH or N; and
Y 2 is N or CR 9 ; wherein R 9 is selected from hydrogen and methyl.

8. A pharmaceutical composition comprising one or more RNAi agents of claim 1 , and at least one pharmaceutically acceptable excipient.

9. A cell or vector containing the RNAi agent of claim 1 .

10. The RNAi agent of claim 1 , wherein the second strand is less than about 49 nucleotides in length and comprises at least 19 contiguous nucleotides differing by 0, or 1 nucleotides from the nucleotide sequence (5′ to 3′) GACAGUAUUCUCAGUGCUU (SEQ ID NO: 71).

11. The RNAi agent of claim 10 , wherein the first strand and second strand comprise the duplex pair of SEQ ID NOs: 378/290; 484/438; 485/438; 486/438; 487/438; 488/438; 489/438; 490/438; 491/438; 492/438; 493/438; 494/438; 495/438; 496/438; 497/438; 498/438; 499/438; 500/438; 501/438; 502/438; or 503/439.

12. A double-stranded RNAi agent for inhibiting expression of an APOC3 gene in a cell, the RNAi agent comprising a first strand and a second strand wherein the first strand and second strand comprise the duplex pair of SEQ ID NOs: 484/438, 485/438, 486/438; 487/438; 488/438; 489/438; 491/438; 496/438; 497/438; 498/438; 499/438; 501/438; 502/438; or 503/439.
