Description

METHODS FOR TREATING HYPERCHOLESTEROLEMIA

FIELD OF THE INVENTION Methods are provided for lowering LDL-C levels in an individual having elevated LDL-

C levels. Such methods are further useful to treat hypercholesterolemia, and to reduce the risk of coronary heart disease.

BACKGROUND Atherosclerosis is a complex, polygenic disease of arterial degeneration that can lead to coronary heart disease (CHD). In Western societies, complications arising from atherosclerosis are the most common causes of death. Several risk factors for CHD have been well-established, and include elevated low density lipoprotein-cholesterol (LDL-C), low levels of high density lipoprotein cholesterol (HDL-C), cigarette smoking, hypertension, age, and family history of early CHD. Given the abundant clinical data and epidemiological studies indicating that lowering LDL-C is beneficial for the prevention of adverse coronary events, the primary target of pharmacological intervention in the treatment and prevention of CHD is lowered LDL-C.

In individuals with autosomal dominant hypercholesterolemia (ADH), elevated LDL-C levels have been linked to mutations in the genes encoding LDL-receptor (LDL-R), apolipoprotein B (apoB), or proprotein convertase subtilisin/kexin type 9 (PCSK9) (Abifadel et al., Nat. Genet., 2003, 34: 154-156). The PCSK9 gene (also known as FH3; NARCl ; NARC-I ; and HCHOLA3) was mapped to Chromosome 1 at location Ip32.3. PCSK9 was identified as a third locus associated with ADH when gain-of-function mutations in PCSK9 were found to be linked to elevated LDL-C levels. ApoB-100 participates in the intracellular assembly and secretion of triglyceride-rich lipoproteins and is a ligand for the LDL-R. PCSK9 is proposed to reduce LDL-R expression levels in the liver. Reduced LDL-R expression results in reduced hepatic uptake of circulating apoB-100-containing lipoproteins, which in turn leads to elevated cholesterol.

Familial hypercholesterolemia (FH) is caused by hundreds of different mutations in the LDL-R, and is phenotypically characterized by elevated plasma LDL-C levels and deposits of LDL-C in tendons, skin and arteries, leading to premature cardiovascular disease. Homozygous and heterozygous mutations in the LDL-R are associated with FH. Likewise, heterozygous and homozygous mutations in the ligand-binding domain of PCSK9 are associated with the FH phenotype. Mutations in this gene have been associated with a third form of autosomal dominant FH.

In mice genetically deficient in PCSK9, a marked increase in LDL-R expression and increased plasma LDL clearance rate were observed. Conversely, overexpression in mice of wild-type PCSK9, or certain PCSK9 mutants, promotes decreased LDL-R expression and elevated LDL-C levels.

Overview

Elevated levels of LDL-cholesterol (HDL-C) are recognized as a major independent risk factor for coronary heart disease (CHD). Even in individuals undergoing aggressive treatment with currently available cholesterol-lowering agents to reduce LDL-cholesterol (LDL-C) levels, coronary events still occur, and elevated LDL-C levels remain a major risk factor for coronary heart disease in these individuals. Furthermore, many individuals undergoing LDL-lowering therapy do not reach their target LDL-C levels, and thus remain at risk for CHD. Accordingly, there is a need for additional LDL-C lowering agents.

The antisense compounds and methods provided herein are useful for the treatment of hypercholesterolemia. Treatment of hypercholesterolemia encompasses a therapeutic regimen that results in a clinically desirable outcome. For example, the antisense compounds and methods provided herein are useful for the treatment of elevated cholesterol, such as elevated LDL-C. In addition, the antisense compounds and methods provided herein may be used to reduce the risk of CHD, in individuals exhibiting one or more risk factors for CHD. Furthermore, the antisense compounds and methods provided herein may be used to treat and/or prevent atherosclerosis. As illustrated herein, administration of an antisense oligonucleotide targeted to PCSK9 to animals fed a high-fat diet (an experimental model of hyperlipidemia) resulted in antisense inhibition of PCSK9, upregulation of the LDL-R, reduction of LDL-C levels, and reduction of liver triglycerides. Thus, it is demonstrated that in an experimental model of hyperlipidemia, antisense inhibition of PCSK9 results in lowering LDL-C levels. Accordingly, provided herein are methods for the treatment of reducing LDL-C levels through the administration of an antisense compound targeted to a PCSK9 nucleic acid. Increased LDL-C levels are considered a risk factor for CHD, and are also linked to atherosclerosis. Accordingly, also provided herein are methods for the reduction of CHD risk, and for the prevention and/or treatment of atherosclerosis. Also provided herein are methods for the treatment of conditions characterized by elevated liver triglycerides, such as hepatic steatosis.

In certain embodiments, antisense compounds target a range of a PCSK9 nucleic acid. In certain embodiment, such compounds contain at least an 8 nucleotide core sequence in common. In certain embodiments, such compounds sharing at least an 8 nucleotide core sequence targets the following nucleotide regions of SEQ ID: 1 : 320-405, 441 -445, 527-544, 582-590, 744-781 , 81 1-820, 918-922, 953-959, 1034-1036, 1 152-1 153, 1 174-1 199, 1251-1272, 1445-1464, 1603- 1604, 1625-1627, 1707-1734, 1766-181 1, 1832-1848, 1880-1904, 1956-1961 , 1982-1939, 2030- 2039, 2060-2099, 2140-2149, 2170-2186, 2207-2304, 2355-2409, 2435-2503, 2529-2581 , 2626- 2648, 2669-2749, 2770-2827, 2856-2876, 2891-2899, 2930-2982, 3014-3226, 3253-3436, 3457- 3471, or 3497-3542. In certain embodiments, a shortened or truncated antisense compound targeted to a

PCSK9 nucleic acid has a single subunit deleted from the 5' end (5' truncation), or alternatively from the 3' end (3' truncation). A shortened or truncated antisense compound targeted to a PCSK9 nucleic acid may have two subunits deleted from the 5' end, or alternatively may have two subunits deleted from the 3' end, of the antisense compound. Alternatively, the deleted nucleosides may be dispersed throughout the antisense compound, for example, in an antisense compound having one nucleoside deleted from the 5' end and one nucleoside deleted from the 3' end.

When a single additional subunit is present in a lengthened antisense compound, the additional subunit may be located at the 5' or 3' end of the antisense compound. When two are more additional subunits are present, the added subunits may be adjacent to each other, for example, in an antisense compound having two subunits added to the 5' end (5' addition), or alternatively to the 3' end (3' addition), of the antisense compound. Alternatively, the added subunits may be dispersed throughout the antisense compound, for example, in an antisense compound having one subunit added to the 5' end and one subunit added to the 3' end. It is possible to increase or decrease the length of an antisense compound, such as an antisense oligonucleotide, and/or introduce mismatch bases without eliminating activity. For example, in Woolf et al. (Proc. Natl. Acad. Sci. USA 89:7305-7309, 1992), a series of antisense oligonucleotides 13-25 nucleobases in length were tested for their ability to induce cleavage of a target RNA in an oocyte injection model. Antisense oligonucleotides 25 nucleobases in length with 8 or 1 1 mismatch bases near the ends of the antisense oligonucleotides were able to direct specific cleavage of the target mRNA, albeit to a lesser extent than the antisense oligonucleotides that contained no mismatches. Similarly, target specific cleavage was achieved using 13 nucleobase antisense oligonucleotides, including those with 1 or 3 mismatches. Gautschi et al (J. Natl. Cancer Inst. 93:463-471, March 2001) demonstrated the ability of an oligonucleotide having 100% complementarity to the bcl-2 mRNA and having 3 mismatches to the bcl-xL mRNA to reduce the expression of both bcl-2 and bcl-xL in vitro and in vivo. Furthermore, this oligonucleotide demonstrated potent anti-tumor activity in vivo. Maher and Dolnick (Nuc. Acid. Res. 16:3341-3358,1988) tested a series of tandem 14 nucleobase antisense oligonucleotides, and a 28 and 42 nucleobase antisense oligonucleotides comprised of the sequence of two or three of the tandem antisense oligonucleotides, respectively, for their ability to arrest translation of human DHFR in a rabbit reticulocyte assay. Each of the three 14 nucleobase antisense oligonucleotides alone was able to inhibit translation, albeit at a more modest level than the 28 or 42 nucleobase antisense oligonucleotides.

PCT/US2007/068404 describes incorporation of chemically-modified high-affinity nucleotides into short antisense compounds about 8-16 nucleobases in length and that such compounds are useful in the reduction of target RNAs in animals with increased potency and improved therapeutic index. In certain embodiments, antisense compounds targeted to a PCSK9 nucleic acid are short antisense compounds. In certain embodiments, such short antisense compounds are oligonucleotide compounds. In certain embodiments, such short antisense compounds are about 8 to 16, preferably 9 to 15, more preferably 9 to 14, more preferably 10 to 14 nucleotides in length and comprises a gap region flanked on each side by a wing, wherein each wing independently consists of 1 to 3 nucleotides. Preferred motifs include but are not limited to wing - deoxy gap -wing motifs selected from 3-10-3, 2-10-3, 2-10-2, 1 -10-1 , 2-8-2, 1-8-1 , 3-6-3 or 1 - 6-1.

Antisense compounds targeted to a PCSK9 nucleic acid are synthesized in vitro and do not include antisense compositions of biological origin, or genetic vector constructs designed to direct the in vivo synthesis of antisense molecules.

In certain embodiments, an antisense compound is targeted to a region of a PCSK9 nucleic acid that does not contain a single nucleotide polymorphism (SNPs). Incertain embodiments, an antisense compound is targeted to a region of a PCSK9 nucleic acid that does contain a single nucleotide polymorph (SNPs). A single nucleotide polymorphism refers to polymorphisms that are the result of a single nucleotide alteration or the existence of two or more alternative sequences which can be, for example, different allelic forms of a gene. A polymorphism may comprise one or more base changes including, for example, an insertion, a repeat, or a deletion. In certain embodiments, an antisense oligonucleotide targeted to a PCSK9 nucleic acid overlaps with a SNP at the following positions: 428, 432, 449, 996, 101 1 , 1044, 1317, 1565, 1617, 1618, 1671, 171 1 , 1722, 1836, 191 1. In certain embodiments, the compounds provided herein that target a region of a PCSK9 nucleic acid that contains one or more SNPs will contain the appropriate base substitution, insertion, repeat or deletion such that the compound is fully complementary to the altered PCSK9 nucleic acid sequence.

Antisense Compound Motifs

In certain embodiments, antisense compounds targeted to a PCSK9 nucleic acid have chemically modified subunits arranged in patterns, or motifs, to confer to the antisense compounds properties such as enhanced the inhibitory activity, increased binding affinity for a target nucleic acid, or resistance to degradation by in vivo nucleases.

Chimeric antisense compounds typically contain at least one region modified so as to confer increased resistance to nuclease degradation, increased cellular uptake, increased binding affinity for the target nucleic acid, and/or increased inhibitory activity. A second region of a chimeric antisense compound may serve as a substrate for the cellular endonuclease RNase H, which cleaves the RNA strand of an RNA:DNA duplex.

Antisense compounds having a gapmer motif are considered chimeric antisense compounds. In a gapmer an internal position having a plurality of nucleotides that supports RNaseH cleavage is positioned between external regions having a plurality of nucleotides that are chemically distinct from the nucleosides of the internal region. In the case of an antisense oligonucleotide having a gapmer motif, the gap segment generally serves as the substrate for endonuclease cleavage, while the wing segments comprise modified nucleosides. The regions of a gapmer are differentiated by the types of sugar moieties comprising each distinct region. The types of sugar moieties that are used to differentiate the regions of a gapmer may in some embodiments include β-D-ribonucleosides, β-D-deoxyribonucleosides, 2'-modified nucleosides (such 2'-modified nucleosides may include 2'-MOE, and 2'-0-CH₃, among others), and bicyclic sugar modified nucleosides (such bicyclic sugar modified nucleosides may include those having a 4'-(CH2)n-O-2' bridge, where n=l or n=2). In general, each distinct region comprises uniform sugar moieties. The wing-gap-wing motif is frequently described as "X-Y-Z", where "X" represents the length of the 5' wing region, "Y" represents the length of the gap region, and "Z" represents the length of the 3' wing region. In some embodiments, an antisense compound targeted to a PCSK9 nucleic acid has a gap-widened motif. In other embodiments, an antisense oligonucleotide targeted to a PCSK9 nucleic acid has a gap-widened motif.

The gap-widened antisense oligonucleotides described herein may have various wing- gap-wing motifs selected from: 1-16-1,2-15-1, 1-15-2, 1-14-3,3-14-1,2-14-2, 1-13-4,4-13-1, 2-13-3, 3-13-2, 1-12-5, 5-12-1, 2-12-4, 4-12-2, 3-12-3, 1-11-6, 6-11-1, 2-11-5, 5-11-2, 3-11-4, 4- 11-3, 1-17-1, 2-16-1, 1-16-2, 1-15-3, 3-15-1, 2-15-2, 1-14-4, 4-14-1, 2-14-3, 3-14-2, 1-13-5, 5- 13-1,2-13-4, 4-13-2, 3-13-3, 1-12-6, 6-12-1, 2-12-5, 5-12-2, 3-12-4, 4-12-3, 1-11-7, 7-11-1,2- 11-6,6-11-2,3-11-5,5-11-3,4-11-4, 1-18-1, 1-17-2,2-17-1, 1-16-3, 1-16-3,2-16-2, 1-15-4,4- 15-1,2-15-3, 3-15-2, 1-14-5, 5-14-1, 2-14-4, 4-14-2, 3-14-3, 1-13-6, 6-13-1, 2-13-5, 5-13-2, 3- 13-4, 4-13-3, 1-12-7, 7-12-1, 2-12-6, 6-12-2, 3-12-5, 5-12-3, 4-12-4, 1-11-8, 8-11-1, 2-11-7, 7- 11-2, 3-11-6, 6-11-3, 4-11-5, 5-11-4, 1-18-1, 1-17-2, 2-17-1, 1-16-3, 3-16-1, 2-16-2, 1-15-4, 4- 15-1, 2-15-3, 3-15-2, 1-14-5, 2-14-4, 4-14-2, 3-14-3, 1-13-6, 6-13-1, 2-13-5, 5-13-2, 3-13-4, 4- 13-3, 1-12-7, 7-12-1, 2-12-6, 6-12-2, 3-12-5, 5-12-3, 4-12-4, 1-11-8, 8-11-1, 2-11-7, 7-11-2, 3- 11-6,6-11-3,4-11-5,5-11-4, 1-19-1, 1-18-2,2-18-1, 1-17-3,3-17-1,2-17-2, 1-16-4,4-16-1,2- 16-3, 3-16-2, 1-15-5, 2-15-4, 4-15-2, 3-15-3, 1-14-6, 6-14-1, 2-14-5, 5-14-2, 3-14-4, 4-14-3, 1- 13-7, 7-13-1, 2-13-6, 6-13-2, 3-13-5, 5-13-3, 4-13-4, 1-12-8, 8-12-1, 2-12-7, 7-12-2, 3-12-6, 6- 12-3, 4-12-5, 5-12-4, 2-11-8, 8-11-2, 3-11-7, 7-11-3, 4-11-6, 6-11-4, 5-11-5, 1-20-1, 1-19-2, 2- 19-1, 1-18-3, 3-18-1, 2-18-2, 1-17-4, 4-17-1, 2-17-3, 3-17-2, 1-16-5, 2-16-4, 4-16-2, 3-16-3, 1- 15-6, 6-15-1, 2-15-5, 5-15-2, 3-15-4, 4-15-3, 1-14-7, 7-14-1, 2-14-6, 6-14-2, 3-14-5, 5-14-3, 4- 14-4, 1-13-8, 8-13-1, 2-13-7, 7-13-2, 3-13-6, 6-13-3, 4-13-5, 5-13-4, 2-12-8, 8-12-2, 3-12-7, 7- 12-3, 4-12-6, 6-12-4, 5-12-5, 3-11-8, 8-11-3, 4-11-7, 7-11-4, 5-11-6, 6-11-5, 1-21-1, 1-20-2, 2- 20-1, 1-20-3, 3-19-1, 2-19-2, 1-18-4, 4-18-1, 2-18-3, 3-18-2, 1-17-5, 2-17-4, 4-17-2, 3-17-3, 1- 16-6, 6-16-1, 2-16-5, 5-16-2, 3-16-4, 4-16-3, 1-15-7, 7-15-1, 2-15-6, 6-15-2^ 3-15-5, 5-15-3, 4- 15-4, 1-14-8, 8-14-1, 2-14-7, 7-14-2, 3-14-6, 6-14-3, 4-14-5, 5-14-4, 2-13-8, 8-13-2, 3-13-7, 7- 13-3, 4-13-6, 6-13-4, 5-13-5, 1-12-10, 10-12-1, 2-12-9, 9-12-2, 3-12-8, 8-12-3, 4-12-7, 7-12-4, 5- 12-6, 6-12-5, 4-11-8, 8-11-4, 5-11-7, 7-11-5, 6-11-6, 1-22-1, 1-21-2, 2-21-1, 1-21-3, 3-20-1, 2- 20-2, 1-19-4, 4-19-1, 2-19-3, 3-19-2, 1-18-5, 2-18-4, 4-18-2, 3-18-3, 1-17-6, 6-17-1, 2-17-5, 5- 17-2, 3-17-4, 4-17-3, 1-16-7, 7-16-1, 2-16-6, 6-16-2, 3-16-5, 5-16-3, 4-16-4, 1-15-8, 8-15-1,2- 15-7, 7-15-2, 3-15-6, 6-15-3, 4-15-5, 5-15-4, 2-14-8, 8-14-2, 3-14-7, 7-14-3, 4-14-6, 6-14-4, 5- 14-5, 3-13-8, 8-13-3, 4-13-7, 7-13-4, 5-13-6, 6-13-5, 4-12-8, 8-12-4, 5-12-7, 7-12-5, 6-12-6, 5- 11-8, 8-11-5, 6-11-7, or 7-11-6.

Internucleoside linkages are phosphorthioate, and cytidines are 5-methylcytidines.

Table 14.1: Gapmer antisense compounds having a 2-10-2 motif targeted to SEQ ID NO: 1,

SEQ ID NO: 2 and/or SEQ ID NO: 3

In a certain embodiment, a short antisense compound has increased potency compared to a 20 nucleotide compound. In a certain embodiment such short antisense compound and 20 nucleotide compound target the same region. In a certain embodiment, a short antisense compound has increased potency compared to a 20 nucleotide coumpound containing the sequence of the short antisense compound.

In certain embodiments, the desired effect is a reduction in mRNA target nucleic acid levels. In other embodiments, the desired effect is reduction of levels of protein encoded by the target nucleic acid or a phenotypic change associated with the target nucleic acid.

In one embodiment, a target region is a structurally defined region of the nucleic acid. For example, a target region may encompass a 3' UTR, a 5' UTR, an exon, an intron, a coding region, a translation initiation region, translation termination region, or other defined nucleic acid region. In other embodiments, a target region may encompass the sequence from a 5' target site of one target segment within the target region to a 3' target site of another target segment within the target region.

Targeting includes determination of at least one target segment to which an antisense compound hybridizes, such that a desired effect occurs. A target region may contain one or more target segments. Multiple target segments within a target region may be overlapping.

Alternatively, they may be non-overlapping. In one embodiment, target segments within a target region are separated by no more than about 10 nucleotides on the target nucleic acid. In another embodiment, target segments within a target region are separated by no more than about 5 nucleotides on the target nucleic acid. In additional embodiments, target segments are contiguous.

Suitable target segments may be found within a 5' UTR, a coding region, a 3' UTR, an intron, or an exon. Target segments containing a start codon or a stop codon are also suitable target segments.

The determination of suitable target segments may include a comparison of the sequence of a target nucleic acid to other sequences throughout the genome. For example, the BLAST algorithm may be used to identify regions of similarity amongst different nucleic acids. This comparison can prevent the selection of antisense compound sequences that may hybridize in a non-specific manner to sequences other than a selected target nucleic acid (i.e., non-target or off- target sequences). There may be variation in activity (e.g., as defined by percent reduction of target nucleic acid levels) of the antisense compounds within an active target region. In one embodiment, reductions in PCSK9 mRNA levels are indicative of inhibition of PCSK9 expression. Reductions in levels of a PCSK9 protein are also indicative of inhibition of target mRNA expression. Further, phenotypic changes are indicative of inhibition of PCSK9 expression. For example, a decrease in LDL-C levels is indicative of inhibition of PCSK9 expression.

Hybridization For example, hybridization may occur between an antisense compound disclosed herein and a PCSK9 nucleic acid. The most common mechanism of hybridization involves hydrogen bonding (e.g., Watson-Crick, Hoogsteen or reversed Hoogsteen hydrogen bonding) between complementary nucleobases of the nucleic acid molecules.

Hybridization can occur under varying conditions. Stringent conditions are sequence- dependent and are determined by the nature and composition of the nucleic acid molecules to be hybridized.

Methods of determining whether a sequence is specifically hybridizable to a target nucleic acid are well known in the art. In one embodiment, the antisense compounds provided herein are specifically hybridizable with a PCSK9 nucleic acid.

Complementarity

An antisense compound and a target nucleic acid are complementary to each other when a sufficient number of nucleobases of the antisense compound can hydrogen bond with the corresponding nucleobases of the target nucleic acid, such that a desired effect will occur (e.g., antisense inhibition of a target nucleic acid, such as a PCSK9 nucleic acid).

Non-complementary nucleobases between an antisense compound and a PCSK9 nucleic acid may be tolerated provided that the antisense compound remains able to specifically hybridize to a target nucleic acid. Moreover, an antisense compound may hybridize over one or more segments of a PCSK9 nucleic acid such that intervening or adjacent segments are not involved in the hybridization event (e.g., a loop structure, mismatch or hairpin structure).

In some embodiments, the antisense compounds provided herein are at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98% or at least 99% complementary to a PCSK9 nucleic acid. Percent complementarity of an antisense compound with a target nucleic acid can be determined using routine methods. In other embodiments, the antisense compounds provided herein are fully complementary (i.e, 100% complementary) to a target nucleic acid. For example, antisense compound may be fully complementary to a PCSK9 nucleic acid. As used herein, "fully complementary" means each nucleobase of an antisense compound is capable of precise base pairing with the corresponding nucleobases of a target nucleic acid.

The location of a non-complementary nucleobase may be at the 5' end or 3' end of the antisense compound. Alternatively, the non-complementary nucleobase or nucleobases may be at an internal position of the antisense compound. When two or more non-complementary nucleobases are present, they may be contiguous (i.e. linked) or non-contiguous. In one embodiment, a non-complementary nucleobase is located in the wing segment of a gapmer antisense oligonucleotide.

In one embodiment, antisense compounds up to 20 nucleobases in length comprise no more than 4, no more than 3, no more than 2 or no more than 1 non-complementary nucleobase(s) relative to a target nucleic acid, such as a PCSK9 nucleic acid.

In another embodiment, antisense compounds up to 30 nucleobases in length comprise no more than 6, no more than 5, no more than 4, no more than 3, no more than 2 or no more than 1 non-complementary nucleobase(s) relative to a target nucleic acid, such as a PCSK9 nucleic acid.

The antisense compounds provided herein also include those which are complementary to a portion of a target nucleic acid. As used herein, "portion" refers to a defined number of contiguous (i.e. linked) nucleobases within a region or segment of a target nucleic acid. A "portion" can also refer to a defined number of contiguous nucleobases of an antisense compound. In one embodiment, the antisense compounds are complementary to at least an 8 nucleobase portion of a target segment. In another embodiment, the antisense compounds are complementary to at least a 12 nucleobase portion of a target segment. In yet another embodiment, the antisense compounds are complementary to at least a 15 nucleobase portion of a target segment.

Identity

The antisense compounds provided herein may also have a defined percent identity to a particular nucleotide sequence, SEQ ID NO, or compound represented by a specific Isis number. As used herein, an antisense compound is identical to the sequence disclosed herein if it has the same nucleobase pairing ability. For example, a RNA which contains uracil in place of thymidine in a disclosed DNA sequence would be considered identical to the DNA sequence since both uracil and thymidine pair with adenine. Shortened and lengthened versions of the antisense compounds described herein as well as compounds having non-identical bases relative to the antisense compounds provided herein also are contemplated. The non-identical bases may be adjacent to each other or dispersed throughout the antisense compound. Percent identity of an antisense compound is calculated according to the number of bases that have identical base pairing relative to the sequence to which it is being compared. In one embodiment, the antisense compounds are at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95% or 100% identical to one or more of the antisense compounds disclosed herein.

Modifications A nucleoside is a base-sugar combination. The nucleobase (also known as base) portion of the nucleoside is normally a heterocyclic base moiety. Nucleotides are nucleosides that further include a phosphate group covalently linked to the sugar portion of the nucleoside. For those nucleosides that include a pentofuranosyl sugar, the phosphate group can be linked to the

2', 3' or 5' hydroxyl moiety of the sugar. Oligonucleotides are formed through the covalent linkage of adjacent nucleosides to one another, to form a linear polymeric oligonucleotide.

Within the oligonucleotide structure, the phosphate groups are commonly referred to as forming the internucleoside linkages of the oligonucleotide.

Modifications to antisense compounds encompass substitutions or changes to internucleoside linkages, sugar moieties, or nucleobases. Modified antisense compounds are often preferred over native forms because of desirable properties such as, for example, enhanced cellular uptake, enhanced affinity for nucleic acid target, increased stability in the presence of nucleases, or increased inhibitory activity.

Chemically modified nucleosides may also be employed to increase the binding affinity of a shortened or truncated antisense oligonucleotide for its target nucleic acid. Consequently, comparable results can often be obtained with shorter antisense compounds that have such chemically modified nucleosides.

Modified Internucleoside Linkages

The naturally occuring internucleoside linkage of RNA and DNA is a 3' to 5' phosphodiester linkage. Antisense compounds having one or more modified, i.e. non-naturally occurring, internucleoside linkages are often selected over antisense compounds having naturally occurring internucleoside linkages because of desirable properties such as, for example, enhanced cellular uptake, enhanced affinity for target nucleic acids, and increased stability in the presence of nucleases.

Oligonucleotides having modified internucleoside linkages include internucleoside linkages that retain a phosphorus atom as well as internucleoside linkages that do not have a phosphorus atom. Representative phosphorus containing internucleoside linkages include, but are not limited to, phosphodiesters, phosphotriesters, methylphosphonates, phosphoramidate, and phosphorothioates. Methods of preparation of phosphorous-containing and non-phosphorous- containing linkages are well known.

. In one embodiment, antisense compounds targeted to a PCSK9 nucleic acid comprise one or more modified internucleoside linkages. In some embodiments, the modified internucleoside linkages are phosphorothioate linkages. In other embodiments, each internucleoside linkage of an antisense compound is a phosphorothioate internucleoside linkage.

Modified Sugar Moieties Antisense compounds targeted to a PCSK9 nucleic acid may contain one or more nucleotides having modified sugar moieties. Sugar modifications may impart nuclease stability, binding affinity or some other beneficial biological property to the antisense compounds. The furanosyl sugar ring of a nucleoside can be modified in a number of ways including, but not limited to: addition of a substituent group, particularly at the 2' position; bridging of two non- geminal ring atoms to form a bicyclic nucleic acid (BNA); and substitution of an atom or group such as -S-, -N(R)- or -C(R))(R₂) for the ring oxygen at the 4'-position. Modified sugars include, but are not limited to: substituted sugars, especially 2'-substituted sugars having a 2'-F, 2'-OCH₂ (2'-0Me) or a 2'-O(CH₂)₂-OCH₃ (2'-O-methoxyethyl or 2'-MOE) substituent group; and bicyclic modified sugars (BNAs), having a 4'-(CH₂)_n-O-2' bridge, where n=l or n=2, including α-L- methyleneoxy (4'-CH2-O-2') BNA , β-D-methyleneoxy (4'-CH2-O-2') BNA and ethyleneoxy (4'-(CH2)₂-O-2') BNA. Bicyclic modified sugars also include (6'S)-6'methyl BNA, aminooxy (4'-CH2-O-N(R)-2') BNA, oxyamino (4'-CH2-N(R)-O-2') BNA wherein R is, independently, H, a protecting group or Cl -C 12 alkyl. The substituent at the 2' position can also be selected from allyl, amino, azido, thio, O-allyl, O-CI-CIO alkyl, OCF₃, O(CH₂)₂SCH₃, O(CH₂)₂-O-N(Rm)(Rn), and 0-CH₂-C(=0)-N(Rm)(Rn), where each Rm and Rn is, independently, H or substituted or unsubstituted Cl-C l O alkyl. In certain embodiments, such BNA modified nucleotides are high- affinity nucleotides and their incorporation into antisense compounds allows for increased potency and improved therapeutic index. Methods for the preparations of modified sugars are well known to those skilled in the art.

In nucleotides having modified sugar moieties, the nucleobase moieties (natural, modified or a combination thereof) are maintained for hybridization with an appropriate nucleic acid target. In one embodiment, antisense compounds targeted to a PCSK9 nucleic acid comprise one or more nucleotides having modified sugar moieties. In a suitable embodiment, the modified sugar moiety is 2'-MOE. In other embodiments, the 2'-MOE modified nucleotides are arranged in a gapmer motif.

Modified Nucleobases

Nucleobase (or base) modifications or substitutions are structurally distinguishable from, yet functionally interchangeable with, naturally occurring or synthetic unmodified nucleobases. Both natural and modified nucleobases are capable of participating in hydrogen bonding. Such nucleobase modifications may impart nuclease stability, binding affinity or some other beneficial biological property to antisense compounds. Modified nucleobases include synthetic and natural nucleobases such as, for example, 5-methylcytosine (5-me-C). Certain nucleobase substitutions, including 5-methylcytosine substitutions, are particularly useful for increasing the binding affinity of an antisense compound for a target nucleic acid. For example, 5-methylcytosine substitutions have been shown to increase nucleic acid duplex stability by 0.6- 1.2⁰C (Sanghvi, Y. S., Crooke, S.T. and Lebleu, B., eds., Antisense Research and Applications, CRC Press, Boca Raton, 1993, pp. 276-278).

Additional unmodified nucleobases include 5-hydroxymethyl cytosine, xanthine, hypoxanthine, 2-aminoadenine, 6-methyl and other alkyl derivatives of adenine and guanine, 2- propyl and other alkyl derivatives of adenine and guanine, 2-thiouracil, 2-thiothymine and 2- thiocytosine, 5-halouracil and cytosine, 5-propynyl (-C≡C-CH₃) uracil and cytosine and other alkynyl derivatives of pyrimidine bases, 6-azo uracil, cytosine and thymine, 5-uracil (pseudouracil), 4-thiouracil, 8-halo, 8-amino, 8-thiol, 8-thioalkyl, 8-hydroxyl and other 8- substituted adenines and guanines, 5-halo particularly 5-bromo, 5-trifluoromethyl and other 5- substituted uracils and cytosines, 7-methylguanine and 7-methyladenine, 2-F-adenine, 2-amino- adenine, 8-azaguanine and 8-azaadenine, 7-deazaguanine and 7-deazaadenine and 3- deazaguanine and 3-deazaadenine.

Heterocyclic base moieties may also include those in which the purine or pyrimidine base is replaced with other heterocycles, for example 7-deaza-adenine, 7-deazaguanosine, 2- aminopyridine and 2-pyridone. Nucleobases that are particularly useful for increasing the binding affinity of antisense compounds include 5-substituted pyrimidines, 6-azapyrimidines and N-2, N-6 and 0-6 substituted purines, including 2 aminopropyladenine, 5-propynyluracil and 5- propynylcytosine. In one embodiment, antisense compounds targeted to a PCSK9 nucleic acid comprise one or more modified nucleobases. In an additional embodiment, gap-widened antisense oligonucleotides targeted to a PCSK9 nucleic acid comprise one or more modified nucleobases. In some embodiments, the modified nucleobase is 5-methylcytosine. In further embodiments, each cytosine is a 5-methylcytosine.

Compositions and Methods for Formulating Pharmaceutical Compositions

Antisense oligonucleotides may be admixed with pharmaceutically acceptable active and/or inert substances for the preparation of pharmaceutical compositions or formulations. Compositions and methods for the formulation of pharmaceutical compositions are dependent upon a number of criteria, including, but not limited to, route of administration, extent of disease, or dose to be administered.

Certain pharmaceutical compositions for injection are presented in unit dosage form, e.g., in ampoules or in multi-dose containers. Certain pharmaceutical compositions for injection are suspensions, solutions or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents. Certain solvents suitable for use in pharmaceutical compositions for injection include, but are not limited to, lipophilic solvents and fatty oils, such as sesame oil, synthetic fatty acid esters, such as ethyl oleate or triglycerides, and liposomes. Aqueous injection suspensions may contain substances that increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol, or dextran. Optionally, such suspensions may also contain suitable stabilizers or agents that increase the solubility of the pharmaceutical agents to allow for the preparation of highly concentrated solutions. In certain embodiments, a pharmaceutical composition is prepared for transmucosal administration.

Determination of a therapeutically effective amount is well within the capability of those skilled in the art.

In certain embodiments, one or more oligonucleotides of the present invention is formulated as a prodrug. In certain embodiments, upon in vivo administration, a prodrug is chemically converted to the biologically, pharmaceutically or therapeutically more active form of the oligonucleotide. In certain embodiments, prodrugs are useful because they are easier to administer than the corresponding active form. For example, in certain instances, a prodrug may be more bioavailable (e.g., through oral administration) than is the corresponding active form. In certain instances, a prodrug may have improved solubility compared to the corresponding active form. In certain embodiments, prodrugs are less water soluble than the corresponding active form. In certain instances, such prodrugs possess superior transmittal across cell membranes, where water solubility is detrimental to mobility. In certain embodiments, a prodrug is an ester. In certain such embodiments, the ester is metabolically hydrolyzed to carboxylic acid upon administration. In certain instances the carboxylic acid containing compound is the corresponding active form. In certain embodiments, a prodrug comprises a short peptide (polyaminoacid) bound to an acid group. In certain of such embodiments, the peptide is cleaved upon administration to form the corresponding active form. In certain embodiments, a prodrug is produced by modifying a pharmaceutically active compound such that the active compound will be regenerated upon in vivo administration. The prodrug can be designed to alter the metabolic stability or the transport characteristics of a drug, to mask side effects or toxicity, to improve the flavor of a drug or to alter other characteristics or properties of a drug. By virtue of knowledge of pharmacodynamic processes and drug metabolism in vivo, those of skill in this art, once a pharmaceutically active compound is known, can design prodrugs of the compound (see, e.g., Nogrady (1985) Medicinal Chemistry A Biochemical Approach, Oxford University Press, New York, pages 388-392).

Antisense compounds can also be modified to have one or more stabilizing groups that are generally attached to one or both termini of antisense compounds to enhance properties such as, for example, nuclease stability. Included in stabilizing groups are cap structures. These terminal modifications protect the antisense compound having terminal nucleic acid from exonuclease degradation, and can help in delivery and/or localization within a cell. The cap can be present at the 5'-terminus (5'-cap), or at the 3'-terminus (3'-cap), or can be present on both termini. Cap structures are well known in the art and include, for example, inverted deoxy abasic caps. Further 3' and 5'-stabilizing groups that can be used to cap one or both ends of an antisense compound to impart nuclease stability include those disclosed in WO 03/004602 published on January 16, 2003. CeIl Culture and Antisense Compounds Treatment

The effects of antisense compounds on the level, activity or expression of PCSK9 nucleic acids can be tested in vitro in a variety of cell types. Cell types used for such analyses are available from commerical vendors (e.g. American Type Culture Collection, Manassus, VA; Zen-Bio, Inc., Research Triangle Park, NC; Clonetics Corporation, Walkersville, MD) and cells are cultured according to the vendor's instructions using commercially available reagents (e.g. Invitrogen Life Technologies, Carlsbad, CA). Illustrative cell types include, but are not limited to, HepG2 cells, HepB3 cells, and primary hepatocytes.

In vitro Testing of Antisense Oligonucleotides

Described herein are methods for treatment of cells with antisense oligonucleotides, which can be modified appropriately for treatment with other antisense compounds.

In general, cells are treated with antisense oligonucleotides when they cells reach approximately 60-80% confluency in culture.

One reagent commonly used to introduce antisense oligonucleotides into cultured cells includes the cationic lipid transfection reagent LIPOFECTIN® (Invitrogen, Carlsbad, CA). Antisense oligonucleotides are mixed with LIPOFECTIN® in OPTI-MEM® 1 (Invitrogen, Carlsbad, CA) to achieve the desired final concentration of antisense oligonucleotide and a LIPOFECTIN® concentration that typically ranges 2 to 12 ug/mL per 100 nM antisense oligonucleotide.

Another reagent used to introduce antisense oligonucleotides into cultured cells includes LIPOFECTAMINE® (Invitrogen, Carlsbad, CA). Antisense oligonucleotide is mixed with LIPOFECTAMINE® in OPTI-MEM® 1 reduced serum medium (Invitrogen, Carlsbad, CA) to achieve the desired concentration of antisense oligonucleotide and a LIPOFECTAMINE® concentration that typically ranges 2 to 12 ug/mL per 100 nM antisense oligonucleotide.

Cells are treated with antisense oligonucleotides by routine methods. Cells are typically harvested 16-24 hours after antisense oligonucleotide treatment, at which time RNA or protein levels of target nucleic acids are measured by methods known in the art and described herein. In general, when treatments are performed in multiple replicates, the data are presented as the average of the replicate treatments.

The concentration of antisense oligonucleotide used varies from cell line to cell line. Methods to determine the optimal antisense oligonucleotide concentration for a particular cell line are well known in the art. Antisense oligonucleotides are typically used at concentrations ranging from 1 nM to 300 nM.

RNA Isolation RNA analysis can be performed on total cellular RNA or poly(A)+ mRNA. Methods of

RNA isolation are well known in the art. RNA is prepared using methods well known in the art, for example, using the TR1ZOL® Reagent (Invitrogen, Carlsbad, CA) according to the manufacturer's recommended protocols.

Analysis of Inhibition of Target Levels or Expression

Inhibition of levels or expression of a PCSK9 nucleic acid can be assayed in a variety of ways known in the art. For example, target nucleic acid levels can be quantitated by, e.g., Northern blot analysis, competitive polymerase chain reaction (PCR), or quantitaive real-time PCR. RNA analysis can be performed on total cellular RNA or poIy(A)+ mRNA. Methods of RNA isolation are well known in the art. Northern blot analysis is also routine in the art.

Quantitative real-time PCR can be conveniently accomplished using the commercially available ABI PRISM® 7600, 7700, or 7900 Sequence Detection System, available from PE-Applied Biosystems, Foster City, CA and used according to manufacturer's instructions.

Quantitative Real-Time PCR Analysis of Target RNA Levels

Quantitation of target RNA levels may be accomplished by quantitative real-time PCR using the ABI PRISM® 7600, 7700, or 7900 Sequence Detection System (PE-Applied Biosystems, Foster City, CA) according to manufacturer's instructions. Methods of quantitative real-time PCR are well known in the art. Prior to real-time PCR, the isolated RNA is subjected to a reverse transcriptase (RT) reaction, which produces complementary DNA (cDNA) that is then used as the substrate for the real-time PCR amplification. The RT and real-time PCR reactions are performed sequentially in the same sample well. RT and real-time PCR reagents are obtained from Invitrogen (Carlsbad, CA). RT, real-time-PCR reactions are carried out by methods well known to those skilled in the art.

Gene (or RNA) target quantities obtained by real time PCR are normalized using either the expression level of a gene whose expression is constant, such as GAPDH, or by quantifying total RNA using RIBOGREEN® (Invetrogen, Inc. Carlsbad, CA). GAPDH expression is quantified by real time PCR, by being run simultaneously with the target, multiplexing, or separately. Total RNA is quantified using RIBOGREEN® RNA quantification reagent (Invetrogen, Inc. Eugene, OR). Methods of RNA quantification by RIBOGREEN® are taught in Jones, L.J., et al, (Analytical Biochemistry, 1998, 265, 368-374). A CYTOFLUOR® 4000 instrument (PE Applied Biosystems) is used to measure RIBOGREEN® fluorescence.

Probes and primers are designed to hybridize to a PCSK9 nucleic acid. Methods for designing real-time PCR probes and primers are well known in the art, and may include the use of software such as PRIMER EXPRESS® Software (Applied Biosystems, Foster City, CA).

Analysis of Protein Levels

Antisense inhibition of PCSK9 nucleic acids can be assessed by measuring PCSK9 protein levels. Protein levels of PCSK9 can be evaluated or quantitated in a variety of ways well known in the art, such as immunoprecipitation, Western blot analysis (immunoblotting), enzyme- linked immunosorbent assay (ELISA), quantitative protein assays, protein activity assays (for example, caspase activity assays), immunohistochemistry, immunocytochemistry or fluorescence-activated cell sorting (FACS). Antibodies directed to a target can be identified and obtained from a variety of sources, such as the MSRS catalog of antibodies (Aerie Corporation, Birmingham, MI), or can be prepared via conventional monoclonal or polyclonal antibody generation methods well known in the art. Antibodies useful for the detection of human and rat PCSK9 are commercially available.

In vivo Testing of Antisense Compounds

Antisense compounds, for example, antisense oligonucleotides, are tested in animals to assess their ability to inhibit expression of PCSK9 and produce phenotypic changes, such as decreases in LDL-C. Testing may be performed in normal animals, or in experimental disease models. For administration to animals, antisense oligonucleotides are formulated in a pharmaceutically acceptable diluent, such as phosphate-buffered saline. Administration includes parenteral routes of administration, such as intraperitoneal, intravenous, and subcutaneous. Calculation of antisense oligonucleotide dosage and dosing frequency is within the abilities of those skilled in the art, and depends upon factors such as route of administration and animal body weight. Following a period of treatment with antisense oligonucleotides, RNA is isolated from various tissues and changes in PCSK9 nucleic acid expression are measured. Changes in PCSK9 protein levels may also be measured. Animal Models of Atherosclerosis

Example 3: Antisense inhibition of human PSCK9 (HepB3 cells)

Antisense oligonucleotides targeted to a PCSK9 nucleic acid were tested for their effects on PCSK9 mRNA in vitro. Cultured HepB3 cells at a density of 4000 cells per well in a 96-well plate were treated with 75 nM of antisense oligonucleotide. After a treatment period of approximately 24 hours, RNA was isolated from the cells and PCSK9 mRNA levels were measured by quantitative real-time PCR, as described herein. PCSK9 mRNA levels were adjusted according to total RNA content as measured by RIBOGREEN®. Results are presented as percent inhibition of PCSK9, relative to untreated control cells. Antisense oligonucleotides that exhibited at least 30% inhibition of PCSK9 expression are shown in Tables 16, 17 and 18.

The motif column indicates the wing-gap-wing motif of each antisense oligonucleotide. Antisense oligonucleotides were designed as 5-10-5 gapmers, or alternatively as 3-14-3 gapmers, or alternatively as 2-13-5 gapmers where the gap segment comprises 2'-deoxynucleotides and each wing segment comprises 2'-MOE nucleotides. As illustrated in Table 16, 17 and 18, a single nucleobase sequence may be represented by a 5-10-5 motif as well as a 3-14-3 motif as well as a 2-13-5 motif. "5' target site" indicates the 5'-most nucleotide which the antisense oligonucleotide is targeted on the indicated GENBANK Accession No.

Example 10: Antisense inhibition of mouse PCSK9 in vitro

Antisense oligonucleotides were designed to target murine PCSK9, and were evaluated for their ability to reduce PCSK9 mRNA in primary mouse hepatocytes.

Primary mouse hepatocytes were treated with antisense oligonucleotides at doses of 50, 150, or 300 nM, for a period of 24 hours. RNA was isolated using QIAGEN® RNeasy isolation kits and subjected to quantitative real-time PCR using commercially available reagents (Invitrogen, Carlsbad, CA). PCSK9 mRNA levels were measured using a mouse PCSK9 primer probe set, and normalized to G3PDH mRNA levels and/or RIBOGREEN® levels.

ISIS 394814 (GAGCAACTTCGGAGGCAGC, SEQ ID NO: 456) was identified as a potent inhibitor of mouse PCSK9. PCSK9 mRNA levels ISIS 394814 yielded a 50% reduction in PCSK9 mRNA at a concentration of 25 nM (i.e., an IC50 of 25 nM) after a 24 hour incubation with primary mouse hepatocytes. No effect on cultured cell viability was observed.

Example 11: Antisense inhibition of PCSK9 in an animal model of hyperlipidemia: high fat fed mice Treatment

C57BL/6 mice fed a high-fat diet are routinely employed as an animal model of hyperlipidemia, as well as an animal model of atherosclerosis. Accordingly, to evaluate the effects of PCSK9 antisense inhibition on serum lipid levels in vivo, ISIS 394814 was evaluated in C57BL/6 mice fed a high-fat diet. C57BL/6 mice 4-5 weeks of age were obtained from the Jackson Laboratory and maintained on a diet consisting of 60% fat. Treatment groups of 5 mice each were as follows: a group treated with ISIS 394814; a control group treated with saline; and control group treated with an oligonucleotide not complementary to any known gene sequence (ISIS 141923). Oligonucleotide or saline was administered intraperitoneally twice weekly, for a period of 6 weeks; oligonucleotide doses were 50 mg/kg. After the treatment period, whole blood was collected for analysis of serum parameters, and whole liver was collected for RNA analysis, protein analysis, and histological evaluation. Statistical analyses included a nonparametric, two- tailed t-test comparison of experimental samples (ISIS 394814) to control samples (saline or control oligonucleotide). RNA Analysis Liver RNA was isolated for real-time PCR analysis of PCSK9, LDL-receptor and apolipoprotein B mRNA levels. Treatment with ISIS 394814 resulted in a 92% reduction in PCSK9 mRNA levels, while no significant reduction in PCSK9 mRNA levels was observed in ISIS 141923 -treated or saline-treated mice. Antisense inhibition of PCSK9 expression did not significantly affect liver LDL-receptor or liver apolipoprotein B mRNA levels. Protein Analysis

Immunoblotting was performed to assess the effects of PCSK9 antisense inhibition on LDL-receptor protein and apolipoprotein B levels. Protein isolated from mouse liver was subjected to electrophoresis, transferred to a polyvinylidene-fluoride membrane, and subsequently probed with an anti-mouse LDL-receptor antibody and a scavenger receptor Bl (SR-Bl) antibody. Mouse plasma was similarly subjected to electrophoresis and immunoblotting using an anti-mouse apolipoprotein B antibody. Secondary antibodies conjugated to peroxidase were used to detect primary antibodies. Protein bands were visualized using the ECL plus Western blot detection kit (Amersham Biosciences, UK) and quantified using ImageQuant™ analysis software (MolecularDynamics, Santa Clara, CA).

While LDL-receptor mRNA levels were not significantly affected, antisense inhibition of PCSK9 resulted in an approximate 2-fold increase in the level of hepatic LDL-receptor protein relative to 141923-treated controls. No changes in SR-Bl protein were observed. Furthermore, serum apoB-100 levels were significantly reduced by 50%, relative to 141923-treated controls. Serum apoB-48 levels were significantly increased by approximately 3-fold relative to 141923- treated controls. No significant changes in apoA-I protein were observed, relative to 141923- treated controls.

The mRNA levels of the RNA editing enzyme apobec-1 were also measured. Apobec-1 is responsible for the RNA editing that produces apoB-48 in murine liver and intestine. Human apobec-1 is expressed only in intestinal cells, thus these cells are the source of apoB-48 in humans. Antisense inhibition of PCSK9 resulted in an increase in murine hepatic apobec-1 mRNA levels by approximately 2.7 fold compared to saline-treated controls Serum Lipid Analysis Plasma concentrations of total cholesterol, LDL-C, HDL-C, free cholesterol, triglycerides, glucose, ketones, transaminases, and phospholipids were measured using an automated clinical chemistry analyzer (Hitachi Olympus AU400e, Melville, NY). Serum lipoprotein and cholesterol profiling was performed as described by Crooke et al. (> Lipid Res., 2005, 46, 872-884) using a Beckman System Gold 126 HPLC system, a 507e refrigerated autosampler, a 126 photodiode array detector (Beckman Instruments, Fullerton, CA), and a Superose 6 HR 10/30 column (Pfizer, Chicago, IL). HDL, LDL and VLDL fractions were measured at a wavelength of 505 nm and validated with a cholesterol calibration kit. (Sigma).

Administration of ISIS 394814 resulted in a 52% reduction in total cholesterol (saline, 183 mg/dL ± 18; ISIS 141923, 194 mg/dL ± 14; ISIS 394814, 87 mg/dL + 19, p < 0.005) and a 36% reduction in LDL-C (saline 22 mg/dL ± 4; ISIS 141923, 25 mg/dL ± 2; ISIS 394814, 14 mg/dL ± 2, p < 0.005). Serum free cholesterol was reduced by 25% (saline 41 mg/dL ± 10; ISIS 141923, 58 mg/dL ± 3; ISIS 394814, 31 mg/dL ± 5, p < 0.005) and phospholipids were reduced 54% (saline, 354 mg/dL ± 29; ISIS 141923, 383 mg/dL ± 21 ; ISIS 394814, 169 mg/dL ± 35, p < 0.0001). HDL-C was also reduced by approximately 54% (saline, 183 mg/dL ± 18; ISIS 141923, 194 mg/dL ± 14; ISIS 394814, 87 mg/dL ± 19; p < 0.0001 ). HPLC profiling confirmed the reduction of LDL and HDL lipid classes. Liver Triglyceride Analysis Liver triglyceride content was measured according to routine experimental procedures, for example, per procedures described by Desai et al., Diabetes, 2001 , 50:2287-2295.

Antisense inhibition of PCSK9 for 6 weeks reduced liver triglyceride content by approximately 65% (p = 0.01) relative to saline controls. No statistically significant changes in liver triglyceride content following 141923 treatment were observed. Accordingly, one embodiment is a method of lowering LDL-C levels through the administration of an antisense oligonucleotide targeted to a PCSK9 nucleic acid. An additional embodiment includes a method of lowering total cholesterol through the administration of an antisense oligonucleotide targeted to a PCSK9 nucleic acid. An addition embodiment is lowering liver triglycerides by administering an antisense oligonucleotide targeted to a PCSK9 target nucleic acid.

Example 12: Antisense inhibition of PCSK9 in LDL-R deflcient/apoB-100 animals

LDL-receptor (LDL-R)-deficient/apoB-100 animals do not express the LDL-R gene, and express only the apoB-100 form of apoB. PCSK9 antisense oligonucleotide was administered to LDL-R deficient/apoB-100 mice, to evaluate the effects of antisense inhibition of PCSK9 in the absence of the LDL-R. Mice 4-5 weeks of age were maintained on a standard mouse diet. Treatment groups of 5 mice each were as follows: a group treated with ISIS 394814; a control group treated with saline; and control group treated with an oligonucleotide not complementary to any known gene sequence (ISIS 141923). Oligonucleotide or saline was administered intraperitoneal^ twice weekly, for a period of 6 weeks; oligonucleotide doses were 50 mg/kg (100 mg/kg/wk total). Real-time PCR of liver mRNA and serum analyses were performed as described for the C57B1/6 study.

Antisense inhibition of PCSK9 reduced liver PCSK9 mRNA by approximately 90%, relative to saline controls. However, no reduction in serum cholesterol was observed. Liver triglyceride levels were unaffected by antisense inhibition of PCKS9 in these mice. An 80% increase in liver apobecl mRNA levels was observed, relative to saline controls. These data suggest that a functioning LDL-R is required for cholesterol and liver triglyceride reduction via PCSK9 antisense inhibition.
