[0001] Sequence Listing This application is filed with an electronic Sequence Listing, which is provided as a file entitled BIOL0240WOSEQ_ST25.pdf, 320 Kb in size, created on March 30, 2015. The information in the electronic format of this Sequence Listing is incorporated herein by reference in its entirety.

[0002] FIELD OF THE INVENTION Compositions and methods are provided for reducing the expression of soluble superoxide dismutase 1 (SOD-1) mRNA and protein in an animal. Such methods are useful for treating, preventing, or ameliorating neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS), by inhibiting SOD-1 expression in the animal. [Background technology]

[0003] The soluble SOD-1 enzyme (also known as Cu / Zn superoxide dismutase) is one of the superoxide dismutases that provides protection from oxidative damage to biomolecules by catalyzing the dismutation of superoxide to hydrogen peroxide (H2O2) (Fridovich, Annu. Rev. Biochem., 1995, 64, 97-112). Superoxide anion (O2-) is a potentially harmful cellular by-product produced primarily by errors in oxidative phosphorylation in mitochondria (Turrens, J. Physiol. 2003, 552, 335-344).

[0004] Mutations in the SOD-1 gene are associated with dominantly inherited amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease), a disorder characterized by selective degeneration of upper and lower motor neurons (Rowland, N. Engl. J. Med. 2001, 344, 1688-1700). There is strong genetic linkage between familial ALS and missense mutations in the SOD1 gene (Rosen, Nature, 1993, 362, 59-62). The toxicity of mutant SOD1 results from reduced nuclear protection from active enzyme (loss of function in the nucleus) due to early misfolding (gain of function), a process that may be involved in ALS pathogenesis (Sau, Hum. Mol. Genet. 2007, 16, 1604-1618).

[0005] ALS is a devastating, progressive neurodegenerative disease that affects as many as 30,000 Americans at any given time. The progressive degeneration of motor neurons in ALS ultimately leads to their death. As motor neurons die, the brain loses its ability to initiate and control muscle movement. Voluntary muscle activity is progressively affected, and patients in the later stages of the disease can become completely paralyzed.

[0006] There are currently no acceptable options for treating such neurodegenerative diseases, and therefore it is an object of the present invention to provide methods for treating such diseases. Summary of the Invention

[0007] The present invention provides methods, compounds, and compositions for modulating the expression of soluble superoxide dismutase 1 (SOD-1) mRNA and protein. In certain embodiments, compounds useful for modulating the expression of SOD-1 mRNA and protein are antisense compounds. In certain embodiments, the antisense compounds The compound is a modified oligonucleotide.

[0008] In certain embodiments, the modulation can be performed in cells or tissues. In certain embodiments, the cells or tissues are in animals. In certain embodiments, the animals are humans. In certain embodiments, the SOD-1 mRNA level is reduced. In certain embodiments, the SOD-1 protein level is reduced. Such reduction can occur in a time-dependent or dose-dependent manner.

[0009] Also provided are methods, compounds, and compositions useful for preventing, treating, and ameliorating diseases, disorders, and conditions. In certain embodiments, the SOD-1-related diseases, disorders, and conditions are neurodegenerative diseases. In certain embodiments, the neurodegenerative diseases, disorders, and conditions include amyotrophic lateral sclerosis (ALS).

[0010] The above-mentioned diseases, disorders, and conditions may have one or more risk factors, causes, or outcomes in common. Certain risk factors and causes for the development of ALS include aging, personal or family history, or genetic predisposition. However, the majority of ALS cases are sporadic and have no known risk factors. Certain symptoms and outcomes associated with the development of ALS include, but are not limited to, muscle fasciculations, spasms, stiff, rigid muscles (spasticity), muscle weakness affecting the arms or legs, slurred speech and nasal voice, difficulty walking, difficulty chewing or swallowing (dysphagia), difficulty speaking or speaking (dysarthria), weakness or atrophy, spasticity, exaggerated reflexes (hyperreflexia), and the presence of Babinski's sign. As ALS progresses, symptoms and outcomes include weakness of other limbs, possibly with twitching, muscle spasms, and exaggerated and more rapid reflexes; problems with chewing, swallowing, and breathing; drooling may occur; and ultimately paralysis and death.

[0011] In certain embodiments, the method of treatment comprises administering an SOD-1 antisense compound to an individual in need thereof. In certain embodiments, the method of treatment comprises administering an SOD-1 modified oligonucleotide to an individual in need thereof. DETAILED DESCRIPTION OF THE INVENTION

In certain embodiments, antisense compounds targeted to SOD-1 nucleic acids are 30 subunits in length.In certain embodiments, the antisense compound targeted to an SOD-1 nucleic acid has a length of 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, or 80 linked subunits, or in a range defined by any two of the foregoing values. In certain embodiments, the antisense compound is a modified oligonucleotide and the linked subunits are nucleosides.

[0221] In certain embodiments, oligonucleotides targeting SOD-1 nucleic acids may be truncated or truncated. For example, one subunit may be deleted from the 5' end (5' truncation) or the 3' end (3' truncation). In truncated or truncated antisense compounds targeting SOD-1 nucleic acids, two subunits may be deleted from the 5' end of the antisense compound, or two subunits may be deleted from the 3' end of the antisense compound. Alternatively, the deleted nucleosides may be scattered throughout the antisense compound, for example, an antisense compound may have one nucleoside deleted from the 5' end and one nucleoside deleted from the 3' end.

[0222] When one additional subunit is present in an extended antisense compound, the additional subunit can be at the 5'-end or the 3'-end of the antisense compound. When two or more additional subunits are present, the additional subunits can be adjacent to one another, e.g., two subunits can be added to the 5'-end (5'-addition) or the 3'-end (3'-addition) of an antisense compound. Alternatively, the additional subunits can be interspersed throughout the antisense compound, e.g., one subunit can be added to the 5'-end and one subunit can be added to the 3'-end of an antisense compound.

[0223] The length of antisense compounds, such as modified oligonucleotides, can be increased or decreased, and / or mismatched bases can be introduced, without eliminating activity. For example, Woolf et al. (Proc. Natl. Acad. Sci. USA 89:7305-7309, 1992) tested a series of oligonucleotides ranging from 13 to 25 nucleobases in length in an oocyte injection model for their ability to induce cleavage of target RNA. 25 nucleobase-long oligonucleotides with 8 or 11 mismatched bases near the ends of the oligonucleotide were able to direct specific cleavage of target mRNA, although not as effectively as oligonucleotides containing no mismatches. Similarly, target-specific cleavage was achieved using 13 nucleobase antisense oligonucleotides (including those with one or three mismatches).

[0224] Gautschi et al. (J. Natl. Cancer Inst. 93:463-471, March 2001) demonstrated that an oligonucleotide with 100% complementarity to bcl-2 mRNA and three mismatches to bcl-xL mRNA could reduce the expression of both bcl-2 and bcl-xL in vitro and in vivo. Furthermore, this oligonucleotide showed potent antitumor activity in vivo.

[0225] Maher and Dolnick (Nuc. Acid. Res. 16:3341-3358, 1988) tested a series of tandem 14 nucleobase oligonucleotides, as well as 28 nucleobase and 42 nucleobase oligonucleotides composed of two or three of the tandem oligonucleotide sequences, in a rabbit reticulocyte assay for their ability to terminate translation of human DHFR. Each of the three 14 nucleobase oligonucleotides alone was able to inhibit translation, although to a lower degree than either the 28 nucleobase or 42 nucleobase oligonucleotides.

[0226] Antisense compound motif In certain embodiments, antisense compounds targeted to SOD-1 nucleic acids have chemically modified subunits arranged in a pattern or motif that confers properties to the antisense compounds, such as high inhibitory activity, high binding affinity for the target nucleic acid, or resistance to degradation by in vivo nucleases.

[0227] Chimeric antisense compounds typically contain at least one region modified 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 the chimeric antisense compound may optionally serve as a substrate for the cellular endonuclease RNase H, which cleaves the RNA strand of an RNA:DNA duplex.

[0228] Antisense compounds with gapmer motifs are considered chimeric antisense compounds. In gapmers, an inner region with multiple nucleotides that support RNase H cleavage is located between outer regions with multiple nucleotides that are chemically different from the nucleosides of the inner region. In oligonucleotides with gapmer motifs, the gap segment generally serves as a substrate for endonuclease cleavage, while the wing segments contain modified nucleosides. In certain embodiments, the regions of gapmers are distinguished by the type of sugar moiety that makes up each distinct region. The types of sugar moieties used to distinguish the regions of a gapmer can, in some embodiments, include β-D-ribonucleosides, β-D-deoxyribonucleosides, 2'-modified nucleosides (such 2'-modified nucleosides can include 2'-MOE and 2'-O-CH, among others), and bicyclic sugar-modified nucleosides (such bicyclic sugar-modified nucleosides can include those having a 4'-(CH)O-2' bridge (where n=1 or n=2) and a 4'-CH-O-CH-2'). In certain embodiments, the wings can include several modified sugar moieties, including, for example, 2'-MOE. In certain embodiments, the wings can include several modified and unmodified sugar moieties. In certain embodiments, the wings can include various combinations of 2'-MOE nucleosides and 2'-deoxynucleosides.

[0229] The different regions may each contain uniform sugar moieties, different sugar moieties, or alternating sugar moieties. The wing-gap-wing motif is often described as "XYZ," where "X" represents the length of the 5'-wing, "Y" represents the length of the gap, and "Z" represents the length of the 3'-wing. "X" and "Z" may contain uniform sugar moieties, different sugar moieties, or alternating sugar moieties. In certain embodiments, "X" and "Y" may contain one or more 2'-deoxynucleosides. "Y" may contain a 2'-deoxynucleoside. A gapmer, described herein as "XYZ," has a configuration in which the gap is positioned immediately adjacent to each of the 5'-wing and 3'-wing. Thus, there are no intervening nucleotides between the 5'-wing and the gap, or between the gap and the 3'-wing. Any of the antisense compounds described herein may contain a gapmer motif. In certain embodiments, "X" and "Z" are the same, and in other embodiments, "X" and "Z" are different.

[0230] In certain embodiments, gapmers provided herein include 20-mers, for example, having a 5-10-5 motif.

[0231] In certain embodiments, gapmers provided herein include 19-mers, eg, having a 5-9-5 motif.

[0232] In certain embodiments, gapmers provided herein include 18-mers, for example, having a 5-8-5 motif.

[0233] In certain embodiments, gapmers provided herein include 18-mers, for example, with a 4-8-5 motif.

[0234] In certain embodiments, gapmers provided herein include 18-mers, for example, having a 5-8-7 motif.

[0235] In certain embodiments, gapmers provided herein include 18-mers, for example, having a 6-8-6 motif.

[0236] In certain embodiments, gapmers provided herein include 18-mers, for example, having a 6-8-5 motif.

[0237] In certain embodiments, the modified oligonucleotide contains at least one 2'-O-methoxyethyl modified nucleoside, at least one cEt modified nucleoside, and at least one 2'-deoxynucleoside. In certain embodiments, the modified oligonucleotide has any of the following sugar chemical motifs: ekddddddddekekee kekeddddddddekek eeeedddddddddkkee eeeeddddddddekeke eeeeddddddddkekee eeeeddddddddkkeee eeeeeddddddddkkee eeeekddddddddkeee eeeekdddddddkeeee eeekddddddddkeeee eeekkdddddddkkeee eekkdddddddddkkee eekkddddddddeeeee eekkddddddddkkeee ekekddddddddeeeee ekekddddddddkekee kekeddddddddeeeee where: e = 2'-O-methoxyethyl ribose modified sugar; k=cEt modified sugar, d = 2'-deoxyribose sugar.

[0238] Target nucleic acids, target regions and nucleotide sequences Nucleotide sequences encoding SOD-1 include, but are not limited to, GENBANK Accession No. NM_000454.4 (incorporated herein as SEQ ID NO:1), GENBANK Accession No. NT_011512.10 truncated from nucleotide 18693000 to nucleotide 18704000 (incorporated herein as SEQ ID NO:2), and the complement of GENBANK Accession No. NW_001114168.1 truncated from nucleotide 2258000 to nucleotide 2271000 (incorporated herein as SEQ ID NO:3).

[0239] It is understood that the sequences shown in each SEQ ID NO in the examples provided herein are independent of any modifications to the sugar moiety, internucleoside linkage, or nucleobase. Thus, antisense compounds defined by SEQ ID NO can independently contain one or more modifications to the sugar moiety, internucleoside linkage, or nucleobase. Antisense compounds described by Isis number (Isis No) represent combinations of nucleobase sequences and motifs.

[0240] In certain embodiments, the target region is a structurally defined region of the target nucleic acid. For example, the target region can include 3'UTR, 5'UTR, exon, intron, exon / intron junction, coding region, translation initiation region, translation termination region, or other distinct nucleic acid region. In the case of SOD-1, the structurally defined region can be obtained from a sequence database such as NCBI by accession number, and such information is incorporated herein by reference. In certain embodiments, the target region can include the sequence from the 5' target site of one target segment within the target region to the 3' target site of another target segment within the target region.

[0241] Targeting comprises determining at least one target segment that antisense compound hybridizes to produce desired effect.In certain embodiments, said desired effect is the reduction of mRNA target nucleic acid level.In certain embodiments, said desired effect is the reduction of the protein level that target nucleic acid encodes or the reduction of the phenotypic changes associated with target nucleic acid.

[0242] A target region may contain one or more target segments. Multiple target segments within a target region may overlap. Alternatively, multiple target segments may not overlap. In certain embodiments, target segments within a target region are about 3. In certain embodiments, target segments within a target region are separated by 250, 200, 150, 100, 90, 80, 70, 60, 50, 40, 30, 20, or 10 nucleotides on the target nucleic acid, or by approximately, or less than, or about, or less than, or a range defined by any two of the aforementioned values. In certain embodiments, target segments within a target region are separated by 5 or less, or about 5 or less nucleotides on the target nucleic acid. In certain embodiments, the target segments are contiguous. Target regions defined by a range having a starting nucleic acid that is any of the 5' target sites or 3' target sites listed herein are contemplated.

[0243] Suitable target segments can be found in any of the 5'UTR, coding region, 3'UTR, intron, exon, or exon / intron junction.The target segment containing the start codon or stop codon is also suitable target segment.Suitable target segments can specifically exclude certain structurally distinct regions such as the start codon or stop codon.

[0244] The determination of suitable target segment can include comparing target nucleic acid sequence with other sequences in genome.For example, BLAST algorithm can be used to identify similar regions among various nucleic acids.This comparison can prevent the selection of antisense compound sequence that can nonspecifically hybridize with sequences other than the selected target nucleic acid (i.e., non-target sequence or off-target sequence).

[0245] Variation in the activity of antisense compounds (e.g., as defined by percent reduction in target nucleic acid levels) may occur within an active target region. In certain embodiments, a reduction in SOD-1 mRNA levels indicates inhibition of SOD-1 protein expression. A reduction in SOD-1 protein levels also indicates inhibition of target mRNA expression. A phenotypic change indicates inhibition of SOD-1 expression. An improvement in neurological function indicates inhibition of SOD-1 expression. An improvement in motor function indicates inhibition of SOD-1 expression.

[0246] Hybridization In some embodiments, hybridization occurs between the antisense compounds disclosed herein and SOD-1 nucleic acids. The most common hybridization mechanism involves hydrogen bonding (e.g., Watson-Crick, Hoogsteen, or reversed Hoogsteen hydrogen bonding) between complementary nucleobases of nucleic acid molecules.

[0247] Hybridization can occur under a variety of conditions. Stringent conditions are sequence-dependent and are determined by the nature and composition of the nucleic acid molecules to be hybridized.

[0248] Methods for determining whether a sequence is capable of specifically hybridizing to a target nucleic acid are well known in the art. In certain embodiments, the antisense compounds provided herein are capable of specifically hybridizing to an SOD-1 nucleic acid.

[0249] Complementarity An antisense compound and a target nucleic acid are complementary to one another when a sufficient number of the nucleobases of the antisense compound are capable of hydrogen bonding with corresponding nucleobases of the target nucleic acid in a manner that produces the desired effect (e.g., antisense inhibition of the target nucleic acid, such as an SOD-1 nucleic acid).

[0250] Non-complementary nucleobases between an antisense compound and an SOD-1 nucleic acid may be present in the antisense This is acceptable as long as the compound is still able to specifically hybridize to the target nucleic acid. Additionally, antisense compounds may hybridize across one or more segments of an SOD-1 nucleic acid in a manner such that intervening or adjacent segments are not involved in the hybridization event (e.g., loop structures, mismatches, or hairpin structures).

[0251] In certain embodiments, the antisense compounds provided herein, or specified portions thereof, are 70%, 80%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% complementary or at least 70%, 80%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% homologous to an SOD-1 nucleic acid, target region, target segment, or specified portion thereof. The percent complementarity between an antisense compound and a target nucleic acid can be determined using routine methods.

[0252] For example, an antisense compound in which 18 of 20 nucleobases of the antisense compound are complementary to the target region and therefore will specifically hybridize would correspond to 90 percent complementarity. In this example, the remaining non-complementary nucleobases may be clustered or interspersed with complementary nucleobases, and need not be contiguous with each other or with complementary nucleobases. Thus, an 18-nucleobase-long antisense compound having four non-complementary nucleobases flanked by two regions that are completely complementary to the target nucleic acid would have a total complementarity of 77.8% to the target nucleic acid and would therefore be within the scope of the present invention. The percent complementarity of an antisense compound to a region of a target nucleic acid can be determined using BLAST (basic local alignment search tool) and PowerBLAST programs (Altschul et al., J. Mol. Biol., 1990, 215, 403) known in the art. 410; Zhang and Madden, Genome Res., 1997, 7, 649-656). Percent homology, percent sequence identity, or percent sequence complementarity can be determined, for example, by the Gap program (Wisconsin Sequence Analysis Package, Version 8 for Unix, Genetics Computer Group, University Research Park, Madison Wis.) using the algorithm of Smith and Waterman (Adv. Appl. Math., 1981, 2, 482-489) using default settings.

[0253] In certain embodiments, the antisense compounds provided herein, or designated portions thereof, are fully complementary (i.e., 100% complementary) to a target nucleic acid or designated portion thereof. For example, an antisense compound can be fully complementary to an SOD-1 nucleic acid, or a target region, segment, or sequence thereof. As used herein, "fully complementary" means that each nucleobase of an antisense compound has the ability to precisely base pair with a corresponding nucleobase of a target nucleic acid. For example, a 20-nucleobase antisense compound is fully complementary to a target sequence that is 400 nucleobases in length if a corresponding 20-nucleobase portion that is fully complementary to the antisense compound is present in the target nucleic acid. The term "fully complementary" can also be used in reference to designated portions of a first nucleic acid and / or a second nucleic acid. For example, a 20-nucleobase portion of a 30-nucleobase antisense compound can be "fully complementary" to a target sequence that is 400 nucleobases in length. A 20 nucleobase portion of a 30 nucleobase oligonucleotide is perfectly complementary to a target sequence if the target sequence has a corresponding 20 nucleobase portion (each nucleobase being complementary to the 20 nucleobase portion of the antisense compound). At the same time, the entire 30 nucleobase antisense compound is complementary to the target sequence if the remaining 10 nucleobases of the antisense compound are also complementary to the target sequence. It may or may not be perfectly complementary to the target sequence, depending on whether it is complementary to the target sequence.

[0254] The position of the non-complementary nucleobase may be at the 5'-end or 3'-end of the antisense compound. Alternatively, one or more non-complementary nucleobases may be located 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 discontinuous. In one embodiment, the non-complementary nucleobase is located within the wing segment of a gapmer oligonucleotide.

[0255] In certain embodiments, antisense compounds that are 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 nucleobases in length or at most 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 nucleobases in length contain no more than 4, no more than 3, no more than 2, or no more than 1 non-complementary nucleobase with respect to a target nucleic acid, such as an SOD-1 nucleic acid, or specified portion thereof.

[0256] In certain embodiments, antisense compounds that are 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30 nucleobases in length or at most 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30 nucleobases in length contain 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 with respect to a target nucleic acid, such as an SOD-1 nucleic acid, or specified portion thereof.

[0257] The antisense compounds provided herein also include those that are complementary to a portion of a target nucleic acid. As used herein, a "portion" refers to a predetermined number of contiguous (i.e., linked) nucleobases within a region or segment of a target nucleic acid. A "portion" can also refer to a predetermined number of contiguous nucleobases of an antisense compound. In certain embodiments, an antisense compound is complementary to at least an 8 nucleobase portion of a target segment. In certain embodiments, an antisense compound is complementary to at least a 9 nucleobase portion of a target segment. In certain embodiments, an antisense compound is complementary to at least a 10 nucleobase portion of a target segment. In certain embodiments, an antisense compound is complementary to at least an 11 nucleobase portion of a target segment. In certain embodiments, an antisense compound is complementary to at least a 12 nucleobase portion of a target segment. In certain embodiments, an antisense compound is complementary to at least a 13 nucleobase portion of a target segment. In certain embodiments, an antisense compound is complementary to at least a 14 nucleobase portion of a target segment. In certain embodiments, an antisense compound is complementary to at least a 15 nucleobase portion of a target segment. Antisense compounds complementary to at least a 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 or more nucleobase portion of a target segment, or a range defined by any two of these values, are also contemplated.

[0258] identity The antisense compounds provided herein can also have a certain percent identity with a compound represented by a specific nucleotide sequence, SEQ ID NO: or specific ISIS number, or a portion thereof.In this specification, an antisense compound is identical to the sequence disclosed herein if it has the same nucleic acid base pairing ability.For example, since both uracil and thymidine pair with adenine, RNA containing uracil instead of thymidine in the disclosed DNA sequence will be considered identical to the DNA sequence. The antisense compounds described herein are also contemplated as being truncated and extended, as well as compounds that have non-identical bases compared to the antisense compounds provided herein. The non-identical bases may be adjacent to each other or may be scattered throughout the antisense compound. The percent identity of an antisense compound is calculated according to the number of bases that have identical base pairings compared to the sequence to be compared.

[0259] In certain embodiments, the antisense compound or portion thereof is at least 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99% or 100% identical to one or more of the antisense compounds or SEQ ID NOs or portions thereof disclosed herein.

[0260] In certain embodiments, a portion of the antisense compound is compared with the same length portion of the target nucleic acid.In certain embodiments, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 or 25 nucleobase portion is compared with the same length portion of the target nucleic acid.

[0261] In certain embodiments, a portion of the oligonucleotide is compared with a portion of the target nucleic acid that has the same length. In certain embodiments, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25 nucleobase portions are compared with a portion of the target nucleic acid that has the same length.

[0262] qualification A nucleoside is a base-sugar combination. The nucleobase (also called base) portion of a nucleoside is usually a heterocyclic base moiety. A nucleotide is a nucleoside that further includes a phosphate group covalently linked to the sugar portion of the nucleoside. In the case of nucleosides containing a pentofuranosyl sugar, the phosphate group can be linked to the 2', 3', or 5' hydroxyl moiety of the sugar. Oligonucleotides are formed by covalently linking adjacent nucleosides to each other to form a linear polymer, the oligonucleotide. Within the oligonucleotide structure, the phosphate groups are commonly referred to as forming the internucleoside linkages of the oligonucleotide.

[0263] Modifications of antisense compounds include substitutions or alterations of internucleoside linkages, sugar moieties, or nucleobases. Modified antisense compounds are often preferred over natural forms because of desirable properties such as enhanced cellular uptake, higher affinity for nucleic acid targets, increased stability in the presence of nucleases, or increased inhibitory activity.

[0264] Chemically modified nucleosides can also be used to increase the binding affinity of shortened or truncated oligonucleotides for their target nucleic acids, and as a result, comparable results can often be obtained with shorter antisense compounds having such chemically modified nucleosides.

[0265] Modified internucleoside linkages The naturally occurring internucleoside linkage in 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 chosen over antisense compounds having naturally occurring internucleoside linkages because of desirable properties such as enhanced cellular uptake, higher affinity for nucleic acid targets, and increased stability in the presence of nucleases.

[0266] Oligonucleotides with modified internucleoside linkages contain nucleoside groups in which the phosphorus atom is retained. These include internucleoside linkages and internucleoside linkages that do not contain a phosphorus atom. Representative phosphorus-containing internucleoside linkages include, but are not limited to, phosphodiesters, phosphotriesters, methylphosphonates, phosphoramidates, and phosphorothioates. Methods for preparing phosphorus-containing and non-phosphorus-containing linkages are well known.

[0267] In certain embodiments, the modified oligonucleotide targeting SOD-1 nucleic acid comprises one or more modified internucleoside linkages.In certain embodiments, the modified internucleoside linkages are scattered throughout the antisense compound.In certain embodiments, the modified internucleoside linkages are phosphorothioate linkages.In certain embodiments, each internucleoside linkage of the modified oligonucleotide is a phosphorothioate internucleoside linkage.

[0268] In certain embodiments, modified oligonucleotides targeted to SOD-1 nucleic acids contain one or more phosphodiester internucleoside linkages. In certain embodiments, modified oligonucleotides targeted to SOD-1 nucleic acids contain at least one phosphorothioate internucleoside linkage and at least one phosphodiester internucleoside linkage. In certain embodiments, modified oligonucleotides have the following hybrid backbone motif: sosssssssssoooss, sooossssssssoss, sooosssssssssoss, soossssssssssooss, sooossssssssooss, sooossssssssssooss, sooosssssssssssooss, sooossssssssssssooos, soooosssssssssssooss, sooosssssssssssssooss, sososssssssssssssosos, and sooosssssssssssoooss, where: s = phosphorothioate internucleoside linkage, and o = phosphodiester internucleoside linkage.

[0269] modified sugar moiety Antisense compounds of the present invention can optionally contain one or more nucleosides in which the sugar group has been modified. Such sugar-modified nucleosides may confer superior nuclease stability, increased binding affinity, or some other beneficial biological property to the antisense compound. In certain embodiments, the nucleoside comprises a chemically modified ribofuranose ring moiety. Examples of chemically modified ribofuranose rings include the addition of substituents (5'-substituents, 2'-substituents, bridging of non-geminal ring atoms to form bicyclic nucleic acids (BNAs)), replacement of a ribosyl ring oxygen atom with S, N(R), or C(R1)(R2), where R, R1, and R2 are each independently H, C1-C2, or CI-C1. 12 Examples of chemically modified sugars include, but are not limited to, 2'-F-5'-methyl substituted nucleosides (see PCT International Application WO2008 / 101157, published August 21, 2008, for other 5',2'-bis substituted nucleosides disclosed), or substitution of the ribosyl ring oxygen atom with S and further substitution at the 2' position (see U.S. Patent Application Publication US2005-0130923, published June 16, 2005), or alternatively 5'-substitution of BNAs (wherein LNAs are substituted with, for example, a 5'-methyl group or is substituted with a 5'-vinyl group, see PCT International Application WO2007 / 134181 (published November 22, 2007).

[0270] Examples of nucleosides having modified sugar moieties include, but are not limited to, nucleosides containing 5'-vinyl, 5'-methyl (R or S), 4'-S, 2'-F, 2'-OCH, 2'-OCHCH, 2'-OCHCHF, and 2'-O(CH)OCH substituents. The 2'-position substituent can be allyl, amino, azido, thio, O-allyl, O-C1-C2 10 Alkyl, OCF3, OCH2F, O(CH2)2SCH3, O(CH2)2-ON(R m )(R n ), O-CH2-C(=O)-N(R m )(R n ), and O-CH2-C(=O)-N(R l )-(CH2)2-N(R m )(R n ) can also be selected, in which case each R l , R m and R n are independently H or substituted or unsubstituted C1-C 10 It is alkyl.

[0271] As used herein, the term "bicyclic nucleoside" refers to a modified nucleoside containing a bicyclic sugar moiety. Examples of bicyclic nucleosides (BNAs) include, but are not limited to, nucleosides containing a bridge between the 4'-ribosyl ring atom and the 2'-ribosyl ring atom. In certain embodiments, the antisense compounds provided herein contain one or more BNA nucleosides, where the bridge comprises one of the following formulas: 4'-(CH2)-O-2' (LNA); 4'-(CH2)-S-2'; 4'-(CH2)2-O-2' (ENA); 4'-CH(CH3)-O-2' and 4'-CH(CHOCH3)-O-2' (and analogs thereof; see U.S. Patent No. 7,399,845, issued July 15, 2008); 4'-C(CH3)(CH3)-O-2' (and analogs thereof; See PCT / US2008 / 068922, published as WO / 2009 / 006478 on January 8, 2009; 4'-CH2-N(OCH3)-2' (and analogs thereof; see PCT / US2008 / 064591, published as WO / 2008 / 150729 on December 11, 2008); 4'-CH2-ON(CH3)-2' (see U.S. Patent Application Publication US2004-0171570, published September 2, 2004); 4'-CH2-N(R)-O-2' (where R is H, C1-C 12 alkyl, or a protecting group) (see U.S. Pat.

[0326] 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.

[0327] In certain embodiments, the antisense compound comprises one or more nucleosides having a modified sugar moiety. In certain embodiments, the modified sugar moiety is 2'-MOE. In certain embodiments, the 2'-MOE modified nucleosides are arranged in a gapmer motif. In certain embodiments, the modified sugar moiety is a bicyclic nucleoside having a (4'-CH(CH3)-O-2') bridging group. In certain embodiments, the (4'-CH(CH3)-O-2') modified nucleosides are arranged throughout the wings of the gapmer motif.

[0328] Compositions and methods for formulating pharmaceutical compositions The oligonucleotides may be mixed with pharmacologically acceptable active or inactive substances to prepare pharmaceutical compositions or formulations. The composition and method of formulating the pharmaceutical composition depend on several criteria, including but not limited to, the route of administration, the extent of the disease, or the dosage to be administered.

[0329] Antisense compounds targeted to SOD-1 nucleic acids can be utilized in pharmaceutical compositions by combining the antisense compound with a suitable pharmacologically acceptable diluent or carrier. Pharmacologically acceptable diluents include phosphate buffered saline (PBS). PBS is a suitable diluent for use in parenterally delivered compositions. Thus, in one embodiment, a pharmaceutical composition comprising an antisense compound targeted to SOD-1 nucleic acids and a pharmacologically acceptable diluent is used in the methods described herein. In certain embodiments, the pharmacologically acceptable diluent is PBS. In certain embodiments, wherein the antisense compound is a modified oligonucleotide.

[0330] Pharmaceutical compositions containing antisense compounds include any pharmacologically acceptable salts, esters, or salts of such esters, or any other oligonucleotides that can (directly or indirectly) yield biologically active metabolites or residues thereof when administered to animals, including humans. Thus, for example, the present disclosure also relates to pharmacologically acceptable salts of antisense compounds, prodrugs, pharmacologically acceptable salts of such prodrugs, and other bioequivalents. Suitable pharmacologically acceptable salts include, but are not limited to, sodium and potassium salts.

[0331] Prodrugs may involve the incorporation of additional nucleosides at one or both ends of the antisense compound, which are cleaved by endogenous nucleases in the body to form the active antisense compound.

[0332] Conjugated antisense compounds Antisense compounds can be covalently linked with one or more moieties or conjugates that enhance the activity, cellular distribution, or cellular uptake of the resulting oligonucleotide.Typical conjugate groups include cholesterol moieties and lipid moieties.Additional conjugate groups include carbohydrates, phospholipids, biotin, phenazine, folate, phenanthridine, anthraquinone, acridine, fluorescein, rhodamine, coumarin, and dyes.

[0333] Antisense compounds can also be modified to enhance properties such as nuclease stability by incorporating one or more stabilizing groups, typically attached to one or both ends of the antisense compound. Stabilizing groups include cap structures. These terminal modifications protect antisense compounds with terminal nucleic acids from exonuclease degradation and may aid in intracellular delivery and / or localization. Caps can be present at the 5' end (5' cap) or 3' end (3' cap), or can be present at both ends. Cap structures are well known in the art and include, for example, inverted deoxy abasic caps. Additional 3' and 5' stabilizing groups that can be used to cap one or both ends of an antisense compound to confer nuclease stability include those described in WO 03 / 004602 (published January 16, 2003).

[0334] Cell culture and antisense compound treatment The effect of antisense compounds on SOD-1 nucleic acid concentration, activity, or expression can be tested in vitro in a variety of cell types. Cell types used for such analyses are commercially available from commercial suppliers (e.g., American Type Culture Collection). Cells are available from various suppliers (e.g., Invitrogen Life Technologies, Carlsbad, CA) and are cultured using commercially available reagents according to the supplier's instructions (e.g., Invitrogen Life Technologies, Carlsbad, CA). Exemplary cell types include, but are not limited to, HepG2 cells, Hep3B cells, primary hepatocytes, A431 cells, and SH-SY5Y cells.

[0335] In vitro testing of oligonucleotides Methods for treating cells with oligonucleotides are described herein, but these methods can be modified appropriately for treatment with other antisense compounds.

[0336] Cells can be treated with oligonucleotides when the cells reach approximately 60-80% confluence in culture.

[0337] One commonly used reagent for introducing oligonucleotides into cultured cells is the cationic lipid transfection reagent LIPOFECTIN (Invitrogen, Carlsbad, CA). Oligonucleotides are mixed with LIPOFECTIN in OPTI-MEM1 (Invitrogen, Carlsbad, CA) to achieve the desired final concentration of oligonucleotide and LIPOFECTIN concentrations, which can range from 2 to 12 μg / mL per 100 nM of oligonucleotide.

[0338] Another reagent used to deliver oligonucleotides to cultured cells is LIPOFECTAMINE (Invitrogen, Carlsbad, CA). Oligonucleotides are mixed with LIPOFECTAMINE in OPTI-MEM1 reduced serum medium (Invitrogen, Carlsbad, CA) to achieve the desired oligonucleotide concentration and LIPOFECTAMINE concentration, which can range from 2 to 12 μg / mL per 100 nM of oligonucleotide.

[0339] Another technique used to introduce oligonucleotides into cultured cells is electroporation.

[0340] Cells are treated with oligonucleotides by conventional methods. Cells can be harvested 16-24 hours after oligonucleotide treatment, at which time the RNA or protein levels of the target nucleic acid are measured by methods known in the art and described herein. Generally, when multiple replicate samples are treated, the data are expressed as the average of the replicate treatments.

[0341] The concentration of oligonucleotides used varies depending on the cell line. Methods for determining the optimal oligonucleotide concentration for a particular cell line are well known in the art. When transfecting with lipofectamine, oligonucleotides are typically used at concentrations ranging from 1 nM to 300 nM. When transfecting by electroporation, oligonucleotides are used at higher concentrations ranging from 625 nM to 20,000 nM.

[0342] RNA isolation RNA analysis can be performed on total cell RNA or poly(A)+mRNA.The method of isolating RNA is well known in the art.RNA is prepared by using the method well known in the art, for example, by using TRIZOL reagent (Invitrogen, Carlsbad, CA) according to the manufacturer's recommended protocol.

[0343] Analysis of target levels or inhibition of expression The concentration or inhibition of expression of SOD-1 nucleic acid can be assayed by a variety of methods known in the art. For example, the concentration of target nucleic acid can be quantified by, for example, Northern blot analysis, competitive polymerase chain reaction (PCR), or quantitative real-time PCR. RNA analysis can be performed on total cellular RNA or poly(A)+ mRNA. Methods for isolating RNA are well known in the art. Northern blot analysis is also a common method in the art. Quantitative real-time PCR can be conveniently achieved 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 the manufacturer's instructions.

[0344] Quantitative real-time PCR analysis of target RNA levels Quantitation of target RNA levels was performed using the ABI PRISM 7600, 7700, or 7900 This can be achieved by quantitative real-time PCR using the Sequence Detection System (PE-Applied Biosystems, Foster City, CA) according to the manufacturer's instructions. Methods for quantitative real-time PCR are well known in the art.

[0345] Prior to real-time PCR, the isolated RNA is subjected to a reverse transcriptase (RT) reaction, which generates complementary DNA (cDNA), which is then used as a substrate for 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 available from Invitrogen (Carlsbad, CA). The RT real-time PCR reaction is performed by methods known to those skilled in the art.

[0346] The amount of gene (or RNA) target obtained by real-time PCR is normalized using the expression level of a gene with constant expression, such as cyclophilin A, or by quantifying total RNA using RIBOGREEN (Invitrogen, Inc. Carlsbad, CA). Cyclophilin A expression is quantified by real-time PCR simultaneously with the target, multiplexed, or separately. Total RNA is quantified using RIBOGREEN RNA quantification reagent (Invetrogen, Inc. Eugene, OR). The method for quantifying RNA with RIBOGREEN is SOD-1 ght in Jones, LJ, et al. (Analytical Biochemistry, 1998, 265, 368-374). RIBOGREEN fluorescence is measured using a CYTOFLUOR4000 instrument (PE Applied Biosystems).

[0347] The probes and primers are designed to hybridize to SOD-1 nucleic acids. Methods for designing probes and primers for real-time PCR are well known in the art and can include the use of software such as PRIMER EXPRESS Software (Applied Biosystems, Foster City, CA).

[0348] Analysis of protein levels Antisense inhibition of SOD-1 nucleic acids can be assessed by measuring SOD-1 protein levels. SOD-1 protein levels can be assessed or quantified by various techniques well known in the art, such as immunoprecipitation, Western blot analysis (immunoblotting), enzyme-linked immunosorbent assay (ELISA), quantitative protein assays, protein activity assays (e.g., caspase activity assays), immunohistochemistry, immunocytochemistry, or fluorescence-activated cell sorting (FACS). Antibodies against targets can be identified and obtained from various sources, such as the MSRS catalog of antibodies (Aerie Corporation, Birmingham, MI), or can be prepared by conventional monoclonal or polyclonal antibody generation methods well known in the art. In certain embodiments, the compounds herein result in improved reduction of protein levels.

[0349] In vivo testing of antisense compounds Antisense compounds, e.g., modified oligonucleotides, are tested in animals to assess their ability to inhibit SOD-1 expression and produce phenotypic changes, such as improved motor function. In certain embodiments, motor function is measured in animals by gait initiation analysis, rotarod, grip strength, bar climbing, open field behavior, balance beam, and hind paw footprint tests. Testing can be performed in normal animals or experimental disease models. For administration to animals, oligonucleotides are formulated in a pharmacologically acceptable diluent, such as phosphate-buffered saline. Administration can be intraperitoneal, intravenous, or subcutaneous. Included are parenteral routes of administration such as intravenous administration. The dosage and frequency of administration of the oligonucleotide depend on several factors, including, but not limited to, the route of administration and the body weight of the animal. After a treatment period with the oligonucleotide, RNA is isolated from CNS tissue or CSF to measure changes in SOD-1 nucleic acid expression.

[0381] For example, as described in Example 14 (below), in Sprague-Dawley rats, after 3 hours of treatment with 3 mg of oligonucleotide, ISIS 666922 achieved an FOB score of 3, whereas ISIS 333611 achieved an FOB score of 4. Levels of the microglial marker (IBA1) and the astrocyte marker (GFAP) were also reduced in rats treated with ISIS 666919 compared to rats treated with ISIS 333611.

[0382] ISIS666869 For example, as described in Example 12 (below), when 30 μL of a 16.67 mg / ml oligonucleotide solution diluted in PBS (final dose of 500 μg) was administered, ISIS 666869 achieved 82% inhibition in the lumbar spinal cord and 81% inhibition in the cervical spinal cord of an SOD-1 transgenic rat model, whereas ISIS 333611 achieved 51% inhibition in the lumbar spinal cord and 47% inhibition in the cervical spinal cord.

[0383] ISIS666870 For example, as described in Example 12 (below), when 30 μL of a 16.67 mg / mL solution of the oligonucleotide diluted in PBS (final dose of 500 μg) was administered, ISIS 666870 achieved 76% inhibition in the lumbar spinal cord and 68% inhibition in the cervical spinal cord of an SOD-1 transgenic rat model, whereas ISIS 333611 achieved 51% inhibition in the lumbar spinal cord and 47% inhibition in the cervical spinal cord.

[0384] For example, as described in Example 15 (below), ISIS 666870 exhibited EDs of 139.4 and 1111 (respectively) in lumbar and cervical tissues of SOD-1 transgenic rats when treated intrathecally with 10, 30, 100, 300, or 3000 μg of oligonucleotide. 50 In transgenic rats treated with ISIS 333611, the highest concentration tested (3000 μg) did not achieve more than 55-65% inhibition of human SOD-1 mRNA, suggesting that the ED50 in lumbar and cervical tissues was not significant. 50 could not be calculated.

[0385] For example, as described in Example 17 (below), in SOD-1 transgenic mice, ISIS 666870 showed EDTA values ​​of 148 and 409 in lumbar and cortical tissues (respectively) when treated with an intracerebroventricular bolus of 10, 30, 100, 300, or 700 μg of oligonucleotide. 50 was achieved, whereas the ED achieved with ISIS333611 50 were 401 and 786 in lumbar and cortical tissues (respectively).

[0386] For example, as described in Example 18 (below), after 3 hours of treatment with 700 μg of oligonucleotide, C57bl6 mice achieved an FOB score of 4.75 with ISIS 666870, whereas ISIS 333611 achieved an FOB score of 6.5.

[0387] ISIS666867 For example, as described in Example 12 (below), when 30 μL of a 16.67 mg / mL solution of the oligonucleotide diluted in PBS (final dose of 500 μg) was administered, ISIS 666867 achieved 59% inhibition in the lumbar spinal cord and 48% inhibition in the cervical spinal cord of an SOD-1 transgenic rat model, whereas ISIS 333611 achieved 51% inhibition in the lumbar spinal cord and 47% inhibition in the cervical spinal cord.

Seven areas were assessed, including the tail, hind paws, hind legs, hind end, forward posture, forepaws, and head. The scoring results are presented in the table below. As shown in the table, several of the newly designed oligonucleotides demonstrated better acute tolerability compared to the reference ISIS 333611.

[0530] [Table 64] [Table 64-1] [Table 64-2] [Table 64-3] [Table 64-4] [Table 64-5]

[0531] Tolerability was also assessed 8 weeks after treatment by measuring the levels of the microglial marker IBA1 and the astrocyte marker GFAP in the lumbar spinal cord. Both IBA1 and GFAP are markers of CNS inflammation (Frank, MG, Brain Behav. Immun. 2007, 21, 47-59). In this rat model, higher levels of these markers indicate poorer tolerance of the antisense oligonucleotide.

[0532] IBA1 mRNA levels were measured with primer probe set rAIF1_LTS00219 (forward sequence AGGAGAAAAACAAAGAACACCAGAA, herein referred to as SEQ ID NO:5; reverse sequence CAATTAGGGCAACTCAGAAATAGCT, herein referred to as SEQ ID NO:6; probe sequence CCAACTGGTCCCCCAGCCAAGA, herein referred to as SEQ ID NO:7). GFAP mRNA levels were measured with primer probe set mGFAP_LTS00370 (forward sequence GAAACCAGCTGGACACCAA, herein referred to as SEQ ID NO:8; reverse sequence TCCACAGCTTTACCACGATGTTC, herein referred to as SEQ ID NO:9; probe sequence TCCGTGTCAGAAGGCCACCTCAAGA, herein referred to as SEQ ID NO:10).

[0533] The results are presented in the table below: As shown in the table, some of the newly designed oligonucleotides were better tolerated compared to the reference ISIS333611.

[0534] [Table 65] [Table 65-1] [Table 65-2]

[0535] Example 15: Dose-dependent inhibition of human SOD-1 in a transgenic rat model Gapmers from the studies described above were tested in an SOD-1 transgenic rat model (Taconic, catalog numbers 2148-F and 2148-M), including the reference compound ISIS 333611. These hemizygous rats express mutant human SOD-1 in the spinal cord, many brain regions, and peripheral organs.

[0536] Rats were intrathecally injected with 10, 30, 100, 300, 1000, or 3000 μg of a gapmer listed in the table below, or PBS alone. Animals were sacrificed two weeks later. Inhibition of SOD-1 mRNA in the lumbar spinal cord, cervical spinal cord, rostral cortex, and caudal cortex was assessed by RT-PCR using the primer probe set RTS3898 described in Example 1. Data were collected from ED 50 The data show that these oligonucleotides inhibited SOD1 mRNA more potently than Isis333611 in multiple CNS tissues. In fact, the ED of Isis number 333611 50 A value could not even be calculated because the highest concentration tested (3000 μg) did not inhibit SOD-1 mRNA by more than 55-65%, as indicated by the entry "n / a." "nd" indicates that data is not available for the indicated sample.

[0537] [Table 66]

[0538] Example 16: Tolerance of SOD-1 modified oligonucleotides in rats The gapmers from the above study, along with the reference compound ISIS 333611, were tested for tolerability in Sprague-Dawley rats. Groups of four to six rats received a single intrathecal injection of 1 mg or 3 mg of ISIS oligonucleotides. A control group of rats received an intrathecal injection of PBS. Acute tolerability was assessed 3 hours post-dose as described in Example 14. Results for the 1 mg dose are the average for each group after one experiment. Results for the 3 mg dose are the average for each group over two replicate experiments. The results of this study, presented in the table below, demonstrate that some of the newly designed oligonucleotides are better tolerated than the reference compound ISIS 333611.

[0539] [Table 67]

[0540] Example 17: Dose-dependent inhibition of human SOD-1 in a transgenic mouse model To confirm the results obtained in transgenic rats in another species, gapmers from the above studies were tested in an SOD-1 transgenic mouse model expressing the same G93A human mutant SOD1 gene as expressed by transgenic rats (Examples 12 and 15).

[0541] Mice were given an intracerebroventricular bolus (ICVB) of 10, 30, 100, 300, or 700 μg of the gapmers listed in the table below, or PBS. Animals were sacrificed two weeks later. Inhibition of SOD-1 mRNA in the lumbar spinal cord and cortex was assessed by RT-PCR using the primer probe set RTS3898 described in Example 1. Data are presented below. 50 The data are presented as mean values. The data show that the oligonucleotides inhibited SOD1 mRNA more potently than Isis333611 in both rats and mice.

[0542] [Table 68]

[0543] Example 18: Tolerance of SOD-1 modified oligonucleotides in mice The gapmers from the above study, including the reference compound ISIS 333611, were tested for tolerability in C57bl6 mice. Mice received a single stereotactic intracerebroventricular injection of 700 μg of ISIS oligonucleotides. Control mice received an intracerebroventricular injection of PBS. Acute tolerability was assessed 3 hours after injection using a functional observational global scale (FOB), different from that used for rats. Each mouse was evaluated according to seven different criteria: (1) the mouse was cheerful, alert, and alert; (2) the mouse was motionless or hunched without stimulation; (3) the mouse exhibited any movement without stimulation; (4) the mouse exhibited forward movement after being lifted; (5) the mouse exhibited any movement after being lifted; (6) the mouse responded to a tail pinch; and (7) the mouse had regular breathing. For each of these seven criteria, mice were assigned a subscore of 0 if the criteria was met and 1 if it was not met. After assessing these seven criteria, the subscores were summed for each mouse and then averaged for each group. For example, if a mouse was cheerful, alert, and alert 3 hours after 700 μg ICV administration and met all other criteria, its total score would be 0. If another mouse was not cheerful, alert, or alert 3 hours after 700 μg ICV administration but met all other criteria, it would be given a score of 1. Saline-treated mice generally received a score of 0. Scores at the high end of the range would suggest acute toxicity.

[0544] Body weight was measured throughout the study and is reported below as a percent change from baseline at 8 weeks. Long-term tolerability was assessed by measuring IBA1 and GFAP levels after 8 weeks of administration as described in Example 14. IBA1 and GFAP mRNA levels are reported relative to PBS-treated animals. The results of this study, presented below, demonstrate that several of the newly designed oligonucleotides were better tolerated in rats and mice than the reference ISIS 333611.

[0545] [Table 69]

[0546] [Table 70]

[0547] Example 19: Dose-dependent inhibition of monkey SOD-1 in cynomolgus monkeys Isis #666853 was tested in cynomolgus monkeys. There is one mismatch between Isis #666853 and cynomolgus monkey SOD-1, with 17 consecutive bases in Isis #666853 that are 100% complementary to cynomolgus monkey SOD-1.

[0548] On days 1, 14, 28, 56, and 84 of the study, groups of 6 to 10 male and female monkeys received an intrathecal lumbar bolus of PBS or 4, 12, or 35 mg of Isis #666853. Each group received the same dose on all five dosing days. Animals were sacrificed on day 91. Inhibition of SOD-1 mRNA in the lumbar, thoracic, and cervical spinal cord, as well as the frontal cortex, motor cortex, hippocampus, pons, and cerebellum, was assessed by RT-PCR using primer probe set RTS3898. Data are presented below as the mean percent inhibition for each treatment group relative to the PBS-treated group. These results demonstrate that Isis #666853 inhibited SOD-1 mRNA in multiple target tissues in cynomolgus monkeys.

[0549] Treatment with 666853 was well tolerated over the 13-week study duration, with no clinically observed adverse reactions in monkeys.
