NUCLEIC ACID COMPOUNDS

FIELD

[0001] The present invention provides novel nucleic acid compounds, suitable for therapeutic use. Additionally, the present invention provides methods of making these compounds, as well as methods of using such compounds for the treatment of various diseases and conditions.

BACKGROUND OF THE INVENTION

[0002] Nucleic acid compounds have important therapeutic applications in medicine. Nucleic acids can be used to silence genes that are responsible for a particular disease. Gene-silencing prevents formation of a protein by inhibiting translation. Importantly, gene-silencing agents are a promising alternative to traditional small, organic compounds that inhibit the function of the protein linked to the disease. siRNA, antisense RNA, and micro-RNA are oligonucleotides / oligonucleosides that prevent the formation of proteins by gene-silencing.

[0003] A number of modified siRNA compounds in particular have been developed in the last two decades for diagnostic and therapeutic purposes, including siRNA / RNAi therapeutic agents for the treatment of various diseases including central-nervous-system diseases, inflammatory diseases, metabolic disorders, oncology, infectious diseases, and ocular diseases.

[0004] The present invention relates to nucleic acid compounds, for use in the treatment and / or prevention of disease.

DEFINITIONS

[0052] The “first strand”, also called the antisense strand or guide strand herein and which can be used interchangeably herein, refers to the nucleic acid strand, e.g. the strand of an siRNA, e.g. a dsiRNA, which includes a region that is substantially complementary to a target sequence, e.g. to an mRNA. As used herein, the term "region of complementarity" refers to the region on the antisense strand that is substantially complementary to a sequence, for example a target sequence. Where the region of complementarity is not fully complementary to the target sequence, the mismatches can typically be in the internal or terminal regions of the molecule. In some embodiments, a double stranded nucleic acid e.g. an siRNA agent of the invention includes a nucleoside mismatch in the antisense strand.

[0053] The “second strand” (also called the sense strand or passenger strand herein, and which can be used interchangeably herein), refers to the strand of a nucleic acid e.g. siRNA that includes a region that is substantially complementary to a region of the antisense strand as that term is defined herein. [0054] In the context of molecule comprising a nucleic acid provided with a ligand moiety, optionally also with a linker moiety, the nucleic acid of the invention may be referred to as an oligonucleoside or an oligonucleoside moiety.

[0055] Oligonucleotides are short nucleic acid polymers. Whilst oligonucleotides contain phosphodiester bonds between the nucleoside component thereof (base plus sugar), the present invention is not limited to oligonucleotides always joined by such a phosphodiester bond between adjacent nucleosides, and other oligomers of nucleosides joined by bonds which are bonds other than a phosphodiester bond are contemplated. For example, a bond between nucleosides may be a phosphorothioate bond. Therefore, the term “oligonucleoside” as used herein covers both oligonucleotides and other oligomers of nucleosides. An oligonucleoside which is a nucleic acid having at least a portion which is an oligonucleotide is preferred according to the present invention. An oligonucleoside having one or more, or a majority of, phosphodiester backbone bonds between nucleosides is also preferred according to the present invention. An oligonucleoside having one or more, or a majority of, phosphodiester backbone bonds between nucleosides, and also having one or more phosphorothioate backbone bonds between nucleosides (typically in a terminal region of the first and / or second strands) is also preferred according to the present invention.

[0056] It is preferred herein that the nucleic acid according to the invention is a double stranded oligonucleoside comprising one or more phosphorothioate backbone bonds between nucleosides. Accordingly, in all instances in which the present application refers to an oligonucleotide, particularly in the chemical structures disclosed herein, the oligonucleotide may equally be an oligonucleoside as defined herein.

[0057] In some embodiments, a double stranded nucleic acid e.g. siRNA agent of the invention includes a nucleoside mismatch in the sense strand. In some embodiments, the nucleoside mismatch is, for example, within 5, 4, 3, 2, or 1 nucleosides from the 3 '-end of the nucleic acid e.g. siRNA.

[0058] In another embodiment, the nucleoside mismatch is, for example, in the 3'- terminal nucleoside of the nucleic acid e.g. siRNA.

[0059] A "target sequence" (which may also be called a target RNA or a target mRNA) refers to a contiguous portion of the nucleoside sequence of an mRNA molecule formed during the transcription of a gene, including mRNA that is a product of RNA processing of a primary transcription product. [0060] The target sequence may be from about 10-35 nucleosides in length, e.g., about 15-30 nucleosides in length. For example, the target sequence can be from about 15-30 nucleosides, 15-29, 15-28, 15-27, 15-26, 15-25, 15-24, 15-23, 15-22, 15-21, 15-20, 15-19, 15-18, 15-17,

18-30, 18-29, 18- 28, 18-27, 18-26, 18-25, 18-24, 18-23, 18-22, 18-21, 18-20, 19-30, 19-29,

19-28, 19-27, 19-26, 19-25, 19-24, 19-23, 19-22, 19-21, 19-20, 20-30, 20-29, 20-28, 20-27,

20-26, 20-25, 20-24, 20-23, 20-22, 20- 21, 21-30, 21-29, 21-28, 21-27, 21-26, 21-25, 21-24,

21-23, or 21-22 nucleosides in length. Ranges and lengths intermediate to the above recited ranges and lengths are also contemplated to be part of the invention.

[0061] The term "ribonucleoside" or "nucleoside" can also refer to a modified nucleoside, as further detailed below.

[0062] A nucleic acid can be a DNA or an RNA, and can comprise modified nucleosides. RNA is a preferred nucleic acid.

[0063] The terms "iRNA", “siRNA”, "RNAi agent," and "iRNA agent," "RNA interference agent" as used interchangeably herein, refer to an agent that contains RNA, and which mediates the targeted cleavage of an RNA transcript via an RNA-induced silencing complex (RISC) pathway. siRNA directs the sequence-specific degradation of mRNA through RNA interference (RNAi).

[0064] A double stranded RNA is referred to herein as a "double stranded siRNA (dsiRNA) agent", "double stranded siRNA (dsiRNA) molecule", "double stranded RNA (dsRNA) agent", "double stranded RNA (dsRNA) molecule", "dsiRNA agent", "dsiRNA molecule", or "dsiRNA", which refers to a complex of ribonucleic acid molecules, having a duplex structure comprising two anti-parallel and substantially complementary nucleic acid strands, referred to as having "sense" and "antisense" orientations with respect to a target RNA.

[0065] The majority of nucleosides of each strand of the nucleic acid, e.g. a dsiRNA molecule, are preferably ribonucleosides, but in that case each or both strands can also include one or more non-ribonucleosides, e.g., a deoxyribonucleoside or a modified nucleoside. In addition, as used in this specification, an "siRNA" may include ribonucleosides with chemical modifications.

[0066] The term "modified nucleoside" refers to a nucleoside having, independently, a modified sugar moiety, a modified internucleoside linkage, or modified nucleobase, or any combination thereof. Thus, the term modified nucleoside encompasses substitutions, additions or removal of, e.g., a functional group or atom, to intemucleoside linkages, sugar moieties, or nucleobases. Any such modifications, as used in an siRNA type molecule, are encompassed by "iRNA" or "RNAi agent" or “siRNA” or “siRNA agent” for the purposes of this specification and claims.

[0067] The two strands forming the duplex structure may be different portions of one larger molecule, or they may be separate molecules e.g. RNA molecules.

[0068] The term "nucleoside overhang" refers to at least one unpaired nucleoside that extends from the duplex structure of a nucleic acid according to the present invention. A nucleic acid according to the present invention can comprise an overhang of at least one nucleoside; alternatively the overhang can comprise at least two nucleosides, at least three nucleosides, at least four nucleosides, at least five nucleosides or more. A nucleoside overhang can comprise or consist of a nucleoside/nucleoside analog, including a deoxynucleoside. The overhang(s) can be on the sense strand, the antisense strand, or any combination thereof. Furthermore, the nucleoside(s) of an overhang can be present on the 5'-end, 3'-end, or both ends of either an antisense or sense strand.

[0069] In certain embodiments, the antisense strand has a 1-10 nucleoside, e.g., 0-3, 1-3, 2-4, 2- 5, 4-10, 5-10, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 nucleoside, overhang at the 3'-end or the 5'-end.

[0070] "Blunt" or "blunt end" means that there are no unpaired nucleosides at that end of the double stranded nucleic acid, i.e., no nucleoside overhang. The nucleic acids of the invention include those with no nucleoside overhang at one end or with no nucleoside overhangs at either end.

[0071] Unless otherwise indicated, the term "complementary," when used to describe a first nucleoside sequence in relation to a second nucleoside sequence, refers to the ability of an oligonucleoside comprising the first nucleoside sequence to hybridize and form a duplex structure under certain conditions with an oligonucleoside comprising the second nucleoside sequence, as will be understood by the skilled person. Such conditions can, for example, be stringent conditions, where stringent conditions can include: 400 mM NaCl, 40 mM PIPES pH 6.4, 1 mM EDTA, 50°C or 70°C for 12-16 hours followed by washing (see, e.g., "Molecular Cloning: A Laboratory Manual, Sambrook, et al. (1989) Cold Spring Harbor Laboratory Press).

[0072] Complementary sequences within nucleic acid e.g. a dsiRNA, as described herein, include base-pairing of the oligonucleoside comprising a first nucleoside sequence to an oligonucleoside comprising a second nucleoside sequence over the entire length of one or both nucleoside sequences. Such sequences can be referred to as "fully complementary" with respect to each other herein. However, where a first sequence is referred to as "substantially complementary" or “partially complementary” with respect to a second sequence herein, the two sequences can be fully complementary, or they can form one or more mismatched base pairs, such as 2, 4, or 5 mismatched base pairs, but preferably not more than 5 , while retaining the ability to hybridize under the conditions most relevant to their ultimate application, e.g. , inhibition of gene expression via a RISC pathway. Overhangs shall not be regarded as mismatches with regard to the determination of complementarity. For example, a nucleic acid e.g. dsiRNA comprising one oligonucleoside 17 nucleosides in length and another oligonucleoside 19 nucleosides in length, wherein the longer oligonucleoside comprises a sequence of 17 nucleosides that is fully complementary to the shorter oligonucleoside, can yet be referred to as "fully complementary".

[0073] "Complementary" sequences, as used herein, can also include, or be formed entirely from, non- Watson-Crick base pairs or base pairs formed from non-natural and modified nucleosides, in so far as the above requirements with respect to their ability to hybridize are fulfilled. Such non- Watson-Crick base pairs include, but are not limited to, G:U Wobble or Hoogstein base pairing.

[0074] The terms "complementary," "fully complementary" and "substantially/partially complementary" herein can be used with respect to the base matching between the sense strand and the antisense strand of a nucleic acid eg dsiRNA, or between the antisense strand of a double stranded nucleic acid e.g. siRNA agent and a target sequence.

[0075] Within the present invention, the second strand of the nucleic acid according to the invention, in particular a dsiRNA for inhibiting B4GALT1, is at least partially complementary to the first strand of said nucleic acid. In certain embodiments, a first and second strand of a nucleic acid according to the invention are partially complementary if they form a duplex region having a length of at least 17 base pairs and comprising not more than 1, 2, 3, 4, or 5 mismatched base pairs.

In certain preferred embodiments, the subject is a human.

[0087] The terms "treating" or "treatment" refer to a beneficial or desired result including, but not limited to, alleviation or amelioration of one or more symptoms associated with gene expression. "Treatment" can also mean prolonging survival as compared to expected survival in the absence of treatment. Treatment can include prevention of development of comorbidities, e.g., reduced liver damage in a subject with a hepatic infection.

[0088] "Therapeutically effective amount," as used herein, is intended to include the amount of a nucleic acid e.g. an siRNA that, when administered to a patient for treating a subject having disease, is sufficient to effect treatment of the disease (e.g., by diminishing, ameliorating or maintaining the existing disease or one or more symptoms of disease or its related comorbidities).

[0089] The phrase "pharmaceutically acceptable" is employed herein to refer to compounds, materials, compositions, or dosage forms which are suitable for use in contact with the tissues of human subjects and animal subjects without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.

[0090] The phrase "pharmaceutically-acceptable carrier" as used herein means a pharmaceutically- acceptable material, composition, or vehicle, such as a liquid or solid filler, diluent, excipient, manufacturing aid or solvent encapsulating material, involved in carrying or transporting the subject compound from one organ, or portion of the body, to another organ, or portion of the body. Each carrier must be "acceptable" in the sense of being compatible with the other ingredients of the formulation and not injurious to the subject being treated.

[0091] Where a value or range of values of a parameter are recited, it is intended that values and ranges intermediate to the recited values are also intended to be part of this invention.

[0092] The articles "a" and "an" are used herein to refer to one or to more than one (i.e. to at least one) of the grammatical object of the article.

[0093] The term "including" is used herein to mean, and is used interchangeably with, the phrase "including but not limited to". [0094] The term "or" is used herein to mean, and is used interchangeably with, the term "and/or," unless context clearly indicates otherwise. For example, "sense strand or antisense strand" is understood as "sense strand or antisense strand or sense strand and antisense strand."

[0095] The term "about" is used herein to mean within the typical ranges of tolerances in the art. For example, "about" can be understood as about 2 standard deviations from the mean. In certain embodiments, about means +10%. In certain embodiments, about means +5%. When about is present before a series of numbers or a range, it is understood that "about" can modify each of the numbers in the series or range.

[0096] The term "at least" prior to a number or series of numbers is understood to include the number adjacent to the term "at least", and all subsequent numbers or integers that could logically be included, as clear from context. For example, the number of nucleosides in a nucleic acid molecule must be an integer. For example, "at least 18 nucleosides of a 21 nucleoside nucleic acid molecule" means that 18, 19, 20, or 21 nucleosides have the indicated property. When at least is present before a series of numbers or a range, it is understood that "at least" can modify each of the numbers in the series or range.

[0097] As used herein, "no more than" or "less than" is understood as the value adjacent to the phrase and logical lower values or integers, as logical from context, to zero. For example, a duplex with an overhang of "no more than 2 nucleosides" has a 2, 1, or 0 nucleoside overhang.

[00100] In certain embodiments, there are 1, e.g. 2, e.g. 3, e.g. 4 or more abasic nucleosides present in nucleic acids according to the present invention. Abasic nucleosides are modified nucleosides because they lack the base normally seen at position 1 of the sugar moiety.

Typically, there will be a hydrogen at position 1 of the sugar moiety of the abasic nucleosides present in a nucleic acid according to the present invention. [00101] The abasic nucleosides are in the terminal region of the second strand, preferably located within the terminal 5 nucleosides of the end of the strand. The terminal region may be the terminal 5 nucleosides, which includes abasic nucleosides.

[00104] Preferably there are 2 or at least 2 abasic nucleosides in the terminal region of the second strand, preferably at the terminal and penultimate positions.

[00105] Preferably 2 or more abasic nucleosides are consecutive, for example all abasic nucleosides may be consecutive. For example, the terminal 1 or terminal 2 or terminal 3 or terminal 4 nucleosides may be abasic nucleosides.

[00106] An abasic nucleoside may also be linked to an adjacent nucleoside through a 5 ’-3’ phosphodiester linkage or reversed linkage unless there is only 1 abasic nucleoside at the terminus, in which case it will have a reversed linkage to the adjacent nucleoside.

[00107] A reversed linkage (which may also be referred to as an inverted linkage, which is also seen in the art), comprises either a 5’-5’, a 3’3’, a 3’-2’ or a 2’-3’ phosphodiester linkage between the adjacent sugar moi eties of the nucleosides.

[00108] Abasic nucleosides which are not terminal will have 2 phosphodiester bonds, one with each adjacent nucleoside, and these may be a reversed linkage or may be a 5 ’-3 phosphodiester bond or may be one of each.

[00109] A preferred embodiment comprises 2 abasic nucleosides at the terminal and penultimate positions of the second strand, and wherein the reversed intemucleoside linkage is located between the penultimate (abasic) nucleoside and the antepenultimate nucleoside. [00110] Preferably there are 2 abasic nucleosides at the terminal and penultimate positions of the second strand and the penultimate nucleoside is linked to the antepenultimate nucleoside through a reversed intemucleoside linkage and is linked to the terminal nucleoside through a 5 ’-3’ or 3 ’-5’ phosphodiester linkage (reading in the direction of the terminus of the molecule).

[00111] Preferably a nucleic acid according to the present invention comprises one or more abasic nucleosides, optionally wherein the one or more abasic nucleosides are in a terminal region of the second strand, and/or wherein at least one abasic nucleoside is linked to an adjacent basic nucleoside through a reversed internucleoside linkage.

[00112] Typically the second strand comprises 2 consecutive abasic nucleosides in the 5’ terminal region of the second strand, wherein one such abasic nucleoside is a terminal nucleoside at the 5’ terminal region of the second strand and the other abasic nucleoside is a penultimate nucleoside at the 5’ terminal region of the second strand, wherein: (a) said penultimate abasic nucleoside is connected to an adjacent first basic nucleoside in an adjacent 5’ near terminal region through a reversed internucleoside linkage; and (b) the reversed linkage is a 5-5’ reversed linkage; and (c) the linkage between the terminal and penultimate abasic nucleosides is 3’5’ when reading towards the terminus comprising the terminal and penultimate abasic nucleosides.

[00113] Alternatively the second strand comprises 2 consecutive abasic nucleosides preferably in an overhang in the 3’ terminal region of the second strand, wherein one such abasic nucleoside is a terminal nucleoside at the 3’ terminal region of the second strand and the other abasic nucleoside is a penultimate nucleoside at the 3’ terminal region of the second strand, wherein: (a) said penultimate abasic nucleoside is connected to an adjacent first basic nucleoside in an adjacent 3’ near terminal region through a reversed intemucleoside linkage; and (b) the reversed linkage is a 3-3’ reversed linkage; and (c) the linkage between the terminal and penultimate abasic nucleosides is 5’-3’ when reading towards the terminus comprising the terminal and penultimate abasic nucleosides. More typically, (i) the first strand and the second strand each has a length of 23 nucleosides; (ii) two phosphorothioate internucleoside linkages are respectively between three consecutive positions in said 3’ near terminal region of the second strand, wherein a first phosphorothioate intemucleoside linkage is present between said adjacent first basic nucleoside of (a) and an adjacent second basic nucleoside in said 3’ near terminal region of the second strand, and a second phosphorothioate intemucleoside linkage is present between said adjacent second basic nucleoside and an adjacent third basic nucleoside in said 3’ near terminal region of the second strand; (iii) two phosphorothioate intemucleoside linkages are respectively between three consecutive positions in both 5’ and 3’ terminal regions of the first strand, whereby a terminal nucleoside respectively at each of the 5’ and 3’ terminal regions of said first strand is each attached to a respective 5’ and 3’ adjacent penultimate nucleoside by a phosphorothioate intemucleoside linkage, and each first 5’ and 3’ penultimate nucleoside is attached to a respective 5’ and 3’ adjacent antepenultimate nucleoside by a phosphorothioate intemucleoside linkage; and (iv) the second strand of the nucleic acid is conjugated directly or indirectly to one or more ligand moi eties at the 5’ terminal region of the second strand.

[00114] Examples of the structures are as follows (where the specific RNA nucleosides shown are not limiting and could be any RNA nucleoside):

A A 3 ’-3’ reversed bond (and also showing the 5 ’-3 direction of the last phosphodiester bond between the two abasic molecules reading towards the terminus of the molecule)

B Illustrating a 5’ -5’ reversed bond (and also showing the 3’-5’ direction of the last phosphodiester bond between the two abasic molecules reading towards the terminus of the molecule)

[00115] The abasic nucleoside or abasic nucleosides present in the nucleic acid are provided in the presence of a reversed internucleoside linkage or linkages, namely a 5’ -5’ or a 3 ’-3’ reversed intemucleoside linkage. A reversed linkage occurs as a result of a change of orientation of an adjacent nucleoside sugar, such that the sugar will have a 3’ - 5’ orientation as opposed to the conventional 5’ - 3’ orientation (with reference to the numbering of ring atoms on the nucleoside sugars). The abasic nucleoside or nucleosides as present in the nucleic acids of the invention preferably include such inverted nucleoside sugars. [00116] In the case of a terminal nucleoside having an inverted orientation, then this will result in an “inverted” end configuration for the overall nucleic acid. Whilst certain structures drawn and referenced herein are represented using conventional 5’ - 3’ direction (with reference to the numbering of ring atoms on the nucleoside sugars), it will be appreciated that the presence of a terminal nucleoside having a change of orientation and a proximal 3 ’-3’ reversed linkage, will result in a nucleic acid having an overall 5’- 5’ end structure (i.e. the conventional 3’ end nucleoside becomes a 5’ end nucleoside). Alternatively, it will be appreciated that the presence of a terminal nucleoside having a change of orientation and a proximal 5 ’-5’ reversed linkage will result in a nucleic acid with an overall 3’- 3’ end structure.

[00117] The proximal 3’ -3’ or 5’ -5’ reversed linkage as herein described, may comprise the reversed linkage being directly adjacent / attached to a terminal nucleoside having an inverted orientation, such as a single terminal nucleoside having an inverted orientation. Alternatively, the proximal 3 ’-3’ or 5 ’-5’ reversed linkage as herein described, may comprise the reversed linkage being adjacent 2, or more than 2, nucleosides having an inverted orientation, such as 2, or more than 2, terminal region nucleosides having an inverted orientation, such as the terminal and penultimate nucleosides. In this way, the reversed linkage may be attached to a penultimate nucleoside having an inverted orientation. While a skilled addressee will appreciate that inverted orientations as described above can result in nucleic acid molecules having overall 3’ - 3’ or 5’- 5’ end structures as described herein, it will also be appreciated that with the presence of one or more additional reversed linkages and / or nucleosides having an inverted orientation, then the overall nucleic acid may have 3’ - 5’ end structures corresponding to the conventionally positioned 5’ / 3’ ends.

[00118] In one aspect the nucleic acid may have a 3 ’-3’ reversed linkage, and the terminal sugar moiety may comprise a 5’ OH rather than a 5’ phosphate group at the 5’ position of that terminal sugar.

[00119] A skilled person would therefore clearly understand that 5’- 5’, 3 ’-3’ and 3’ - 5’ (reading in the direction of that terminus) end variants of the more conventional 5’- 3’ structures (with reference to the numbering of ring atoms on the end nucleoside sugars) drawn herein are included in the scope of the disclosure, where a reversed linkage or linkages is / are present. [00120] In the situation of eg a reversed intemucleoside linkage and / or one or more nucleosides having an inverted orientation creating an inverted end, and where the relative position of a linkage (eg to a linker) or the location of an internal feature (such as a modified nucleoside) is defined relative to the 5’ or 3’ end of the nucleic acid, then the 5’ or 3’ end is the conventional 5’ or 3’ end which would have existed had a reversed linkage not been in place, and wherein the conventional 5’ or 3’ end is determined by consideration of the directionality of the majority of the internal nucleoside linkages and / or nucleoside orientation within the nucleic acid. It is possible to tell from these internal bonds and / or nucleoside orientation which ends of the nucleic acid would constitute the conventional 5’ and 3’ ends (with reference to the numbering of ring atoms on the end nucleoside sugars) of the molecule absent the reversed linkage.

[00121] In some embodiments, the second (sense) strand of the nucleic acid according to the invention comprises 2 consecutive abasic nucleosides in the 5’ terminal region as shown in the following 5’ terminal motif wherein:

B represents a nucleoside base,

T represent H, OH or a 2’ ribose modification,

Z represents the remaining nucleosides of said second strand. [00122] In some embodiments, the second (sense) strand of the nucleic acid according to the invention comprises 2 consecutive abasic nucleosides in the 5’ terminal region as shown in the following 5’ terminal motif wherein:

[00123] The reversed bond is preferably located at the end of the nucleic acid eg RNA which is distal to a ligand moiety, such as a GalNAc containing portion, of the molecule.

[00124] GalNAc-siRNA constructs with a 5 ’-GalNAc on the sense strand can have a reversed linkage on the opposite end of the sense strand. [00125] GalNAc-siRNA constructs with a 3’-GalNAc on the sense strand can have a reversed linkage on the opposite end of the sense strand.

Z comprises 19 contiguous nucleosides.

[00145] Preferred nucleic acid comprise one or more nucleosides on the first strand and / or the second strand which are modified, to form modified nucleosides, as follows:

[00146] A nucleic acid wherein the modification is a modification at the 2’ -OH group of the ribose sugar, optionally selected from 2'-Me or 2’-F modifications.

[00147] A nucleic acid wherein the first strand comprises a 2’-F modification at any of position 2, position 6, position 14, or any combination thereof, counting from position 1 of said first strand.

[00148] A nucleic acid wherein the second strand comprises a 2’-F modification at any of position 7, position 9, position 11, or any combination thereof, counting from position 1 of said second strand.

[00149] A nucleic acid wherein the first and second strand each comprise 2'-Me and 2’-F modifications.

[00150] A nucleic which comprises at least one thermally destabilizing modification, suitably at one or more of positions 1 to 9 of the first strand counting from position 1 of the first strand, and / or at one or more of positions on the second strand aligned with positions 1 to 9 of the first strand, wherein the destabilizing modification is selected from a modified unlocked nucleic acid (UNA) and a glycol nucleic acid (GNA), preferably a glycol nucleic acid, more preferably an (S)-glycol nucleic acid.

[00152] A nucleic acid which is an siRNA oligonucleoside, wherein the siRNA oligonucleoside comprises 3 or more 2’-F modifications at positions 6 to 12 of the second strand, such as 4, 5,

6 or 7 2’-F modifications at positions 6 to 12 of the second strand, counting from position 1 of said second strand.

[00153] A nucleic acid which is an siRNA oligonucleoside, wherein said second strand comprises at least 3, such as 4, 5 or 6, 2’-Me modifications at positions 1 to 6 of the second strand, counting from position 1 of said second strand.

[00154] A nucleic acid which is an siRNA oligonucleoside, wherein said first strand comprises at least 5 2’ -Me consecutive modifications at the 3’ terminal region, preferably including the terminal nucleoside at the 3’ terminal region, or at least within 1 or 2 nucleosides from the terminal nucleoside at the 3’ terminal region.

[00155] A nucleic acid which is an siRNA oligonucleoside, wherein said first strand comprises

7 2’ -Me consecutive modifications at the 3’ terminal region, preferably including the terminal nucleoside at the 3’ terminal region.

[00156] A nucleic acid which is an siRNA oligonucleoside, wherein each of the first and second strands comprises an alternating modification pattern, preferably a fully alternating modification pattern along the entire length of each of the first and second strands, wherein the nucleosides of the first strand are modified by (i) 2’Me modifications on the odd numbered nucleosides counting from position 1 of the first strand, and (ii) 2’F modifications on the even numbered nucleosides counting from position 1 of the first strand, and nucleosides of the second strand are modified by (i) 2’F modifications on the odd numbered nucleosides counting from position 1 of the second strand, and (ii) 2’Me modifications on the even numbered nucleosides counting from position 1 of the second strand. Typically such fully alternating modification patterns are present in a blunt ended oligonucleoside, wherein each of the first and second strands are 19 nucleosides in length.

[00157] Position 1 of the first or the second strand is the nucleoside which is the closest to the end of the nucleic acid (ignoring any abasic nucleosides) and that is joined to an adjacent nucleoside (at Position 2) via a 3’ to 5’ internal bond, with reference to the bonds between the sugar moi eties of the backbone, and reading in a direction away from that end of the molecule.

[00158] It can therefore be seen that “position 1 of the sense strand” is the 5’ most nucleoside (not including abasic nucleosides) at the conventional 5’ end of the sense strand. Typically, the nucleoside at this position 1 of the sense strand will be equivalent to the 5’ nucleoside of the selected target nucleic acid sequence, and more generally the sense strand will have equivalent nucleosides to those of the target nucleic acid sequence starting from this position 1 of the sense strand, whilst also allowing for acceptable mismatches between the sequences.

As hereinbefore described, there will be a region of complementarity between the sense and antisense strands, and in this way the antisense strand will also have a region of complementarity to the target nucleic acid sequence as referred to above.

[00160] In certain embodiments, the nucleic acid e.g. siRNA agent further comprises at least one phosphorothioate or methylphosphonate internucleoside linkage. For example the phosphorothioate or methylphosphonate intemucleoside linkage can be at the 3 '-terminus or in the terminal region of one strand, i.e. , the sense strand or the antisense strand; or at the ends of both strands, the sense strand and the antisense strand.

[00161] In certain embodiments, the phosphorothioate or methylphosphonate intemucleoside linkage is at the 5 'terminus or in the terminal region of one strand, i.e. , the sense strand or the antisense strand; or at the ends of both strands, the sense strand and the antisense strand.

[00162] In certain embodiments, a phosphorothioate or a methylphosphonate intemucleoside linkage is at both the 5'- and 3 '-terminus or in the terminal region of one strand, i.e. , the sense strand or the antisense strand; or at the ends of both strands, the sense strand and the antisense strand.

[00163] Any nucleic acid may comprise one or more phosphorothioate (PS) modifications within the nucleic acid, such as at least two PS intemucleoside bonds at the ends of a strand.

[00164] At least one of the oligoribonucleoside strands preferably comprises at least two consecutive phosphorothioate modifications in the last 3 nucleosides of the oligonucleoside.

[00165] The invention therefore also relates to: A nucleic acid disclosed herein which comprises phosphorothioate intemucleoside linkages respectively between at least two or three consecutive positions, such as in a 5’ and/or 3’ terminal region and/or near terminal region of the second strand, whereby said near terminal region is preferably adjacent said terminal region wherein said one or more abasic nucleosides of said second strand is / are located. [00166] A nucleic acid disclosed herein which comprises phosphorothioate intemucleoside linkages respectively between at least two or three consecutive positions in a 5’ and / or 3’ terminal region of the first strand, whereby preferably the terminal position at the 5’ and / or 3’ terminal region of said first strand is attached to its adjacent position by a phosphorothioate intemucleoside linkage.

[00167] The nucleic acid strand may be an RNA comprising a phosphorothioate intemucleoside linkage between the three nucleosides contiguous with 2 terminally located abasic nucleosides.

[00168] A preferred nucleic acid is a double stranded RNA comprising 2 adjacent abasic nucleosides at the 5’ terminus of the second strand and a ligand moiety comprising one or more GalNAc ligand moi eties at the opposite 3’ end of the second strand. Further preferred, the same nucleic acid may also comprise a phosphorothioate bond between nucelotides at positions 3-4 and 4-5 of the second strand, reading from the position 1 of the second strand.

Further preferred, the same nucleic acid may also comprise a 2’ F modification at positions 7, 9 and 11 of the second strand.

Typically, a suitable dose of a nucleic acid e.g. an siRNA of the invention will be in the range of about 0. 1 mg/kg to about 5.0 mg/kg, e.g., about 0.3 mg/kg and about 3.0 mg/kg.

[00271] A repeat-dose regimen may include administration of a therapeutic amount of a nucleic acid e.g. siRNA on a regular basis, such as every other day or once a year. In certain embodiments, the nucleic acid e.g. siRNA is administered about once per month to about once per quarter (i.e., about once every three months).

[00272] In various embodiments, the nucleic acid e.g. siRNA agent is administered at a dose of about 0.01 mg/kg to about 10 mg/kg or about 0.5 mg/kg to about 50 mg/kg. In some embodiments, the nucleic acid e.g. siRNA agent is administered at a dose of about 10 mg/kg to about 30 mg/kg. In certain embodiments, the nucleic acid e.g. siRNA agent is administered at a dose selected from about 0.5 mg/kg 1 mg/kg, 1.5 mg/kg, 3 mg/kg, 5 mg/kg, 10 mg/kg, and 30 mg/kg.

In certain embodiments, the nucleic acid e.g. siRNA agent is administered to the subject once a month. In certain embodiments, the nucleic acid e.g. siRNA agent is administered once per quarter (i.e. , every three months).

[00273] After an initial treatment regimen, the treatments can be administered on a less frequent basis. For example, after administration weekly or biweekly for three months, administration can be repeated once per month, for six months, or a year; or longer.

[00274] The pharmaceutical composition can be administered once daily, or administered as two, three, or more sub-doses at appropriate intervals throughout the day or even using continuous infusion or delivery through a controlled release formulation. In that case, the nucleic acid e.g. siRNA contained in each sub-dose must be correspondingly smaller in order to achieve the total daily dosage. The dosage unit can also be compounded for delivery over several days, e.g. , using a conventional sustained release formulation which provides sustained release of the nucleic acid e.g. siRNA over a several day period. Sustained release formulations are well known in the art and are particularly useful for delivery of agents at a particular site, such as could be used with the agents of the present invention. In this embodiment, the dosage unit contains a corresponding multiple of the daily dose.

[00275] In other embodiments, a single dose of the pharmaceutical compositions can be long lasting, such that subsequent doses are administered at not more than 3, 4, or 5 day intervals, or at not more than 1, 2, 3, or 4 week intervals. In some embodiments of the invention, a single dose of the pharmaceutical compositions of the invention is administered once per week. In other embodiments of the invention, a single dose of the pharmaceutical compositions of the invention is administered bimonthly. In certain embodiments, the siRNA is administered about once per month to about once per quarter (i.e. , about once every three months), or even every 6 months or 12 months.

[00276] Estimates of effective dosages and in vivo half-lives for the individual nucleic acid e.g. siRNAs encompassed by the invention can be made using conventional methodologies or on the basis of in vivo testing using an appropriate animal model, as known in the art.

[00277] The pharmaceutical compositions of the present invention can be administered in a number of ways depending upon whether local or systemic treatment is desired and upon the area to be treated. Administration can be topical {e.g. , by a transdermal patch), pulmonary, e.g. , by inhalation or insufflation of powders or aerosols, including by nebulizer; intratracheal, intranasal, epidermal and transdermal, oral or parenteral. Parenteral administration includes intravenous, intraarterial, subcutaneous, intraperitoneal, or intramuscular injection or infusion; subdermal, e.g. , via an implanted device; or intracranial, e.g. , by intraparenchymal, intrathecal or intraventricular administration. In certain preferred embodiments, the compositions are administered by intravenous infusion or injection. In certain embodiments, the compositions are administered by subcutaneous injection.

[00278] In one embodiment, the nucleic acid e.g. agent is administered to the subject subcutaneously.

[00279] The nucleic acid e.g. siRNA can be delivered in a manner to target a particular tissue {e.g. in particular liver cells).

Combinations of in vitro and in vivo methods of contacting a cell are also possible. Contacting a cell may be direct or indirect, as discussed above.

Furthermore, contacting a cell may be accomplished via a targeting ligand moiety, including any ligand moiety described herein or known in the art. In preferred embodiments, the targeting ligand moiety is a carbohydrate moiety, e.g. a GalNAc3 ligand, or any other ligand moiety that directs the siRNA agent to a site of interest.

[00282] The term "inhibiting," as used herein, is used interchangeably with "reducing," "silencing," "downregulating", "suppressing", and other similar terms, and includes any level of inhibition.

[00283] In some embodiments of the methods of the invention, expression of B4GALT1 gene is inhibited by at least 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, or 95%, or to below the level of detection of the assay, preferably when determined by qPCR as described herein and/or when the siRNA is introduced into the target cell by transfection.

[00286] Inhibition of expression of the B4GALT1 gene may be quantified by the following method:

Huh7 cells (human hepatocyte-derived cell line, obtained from JCRB Cell Bank) may be maintained in Dulbecco’s Modified Eagle Medium (DMEM) supplemented with 10% FBS at 37°C in an atmosphere of 5% CO2. Cells may then be transfected with siRNA duplexes targeting B4GALT1 mRNA or a negative control siRNA (siRNA-control; sense strand 5’- UUCUCCGAACGUGUCACGUTT-3’ (SEQ ID NO:934), antisense strand 5’- ACGUGACACGUUCGGAGAATT-3’ (SEQ ID NO:933)) using 10x3-fold serial dilutions over a final duplex concentration range of 20 nM to 1 pM. Transfection may be carried out by adding 9.7 μL Opti-MEM (ThermoFisher) plus 0.3 μL Lipofectamine RNAiMAX (ThermoFisher) to 10 μL of each siRNA duplex. The mixture may be incubated at room temperature for 15 minutes before being added to 100 μL of complete growth medium containing 20,000 Huh7 cells. Cells may be incubated for 24 hours at 37°C/5% CO2 prior to total RNA purification using a RNeasy 96 Kit (Qiagen). Each duplex may be tested by transfection in duplicate wells in a single experiment. cDNA synthesis may be performed using FastQuant RT (with gDNase) Kit (Tiangen). Realtime quantitative PCR (qPCR) may be performed on an ABI Prism 7900HT or ABI QuantStudio 7 with primers specific for human B4GALT1 (Hs00155245_ml) and human GAPDH (Hs02786624_gl) using a TaqMan Gene Expression Assay Kit (ThermoFisher Scientific).

[00287] qPCR may be performed in duplicate on cDNA derived from each well and the mean cycle threshold (Ct) calculated. Relative B4GALT1 expression may be calculated from mean Ct values using the comparative Ct (AACt) method, normalised to GAPDH and relative to untreated cells. Maximum percent inhibition of B4GALT1 expression and IC50 values may be calculated using a four parameter (variable slope) model using GraphPad Prism 9.

[00288] Alternatively or in addition, the inhibitory potential of a nucleic acid of the invention may be quantified without prior transfection of a target cell with said nucleic acid.

[00289] Thus, in some embodiments, when cells are incubated with a nucleic acid of the invention, the nucleic acid of the invention inhibits expression of the B4GALT1 gene with an EC50 value lower than 1000 nM, 900 nM, 800 nM, 700 nM, 600 nM, 500 nM, 400 nM, 300 nM, 200 nM, or 100 nM, preferably when determined by qPCR, more preferably by reverse transcriptase (RT)-qPCR, as described herein.

[00290] In a preferred embodiment, when cells are incubated with a nucleic acid of the invention, the nucleic acid of the invention inhibits expression of the B4GALT1 gene with an EC50 value lower than 1000 nM. In a more preferred embodiment, when cells are incubated with a nucleic acid of the invention, the nucleic acid of the invention inhibits expression of the B4GALT1 gene with an EC50 value lower than 500 nM. In an even more preferred embodiment, when cells are incubated with a nucleic acid of the invention, the nucleic acid of the invention inhibits expression of the B4GALT1 gene with an EC50 value lower than 200 nM. In a most preferred embodiment, when cells are incubated with a nucleic acid of the invention, the nucleic acid of the invention inhibits expression of the B4GALT1 gene with an EC50 value lower than 100 nM.

[00291] Inhibition of expression of the B4GALT1 gene in the presence of free nucleic acids may be quantified using the following method:

[00292] Primary C57BL/6 mouse hepatocytes (PMHs) may be isolated fresh by two-step collagenase liver perfusion. Cells may be maintained in DMEM (Gibco-11995-092) supplemented with FBS, Penicillin/Streptomycin, HEPES and L-glutamine. Cells may be cultured at 37°C in an atmosphere with 5% CO2 in a humidified incubator. Within 2 hours post isolation, PMHs may be seeded at a density of 36,000 cells/well in regular 96-well tissue culture plates. Dose response analysis in PMHs may be done by direct incubation of cells in a gymnotic free uptake setting with final GalNAc-siRNA concentrations of 1000, 500, 250, 125, 62.5, 31.3, 15.6, 7.8, 3.9, 1.95 nM. In control wells, cells may be incubated without GalNAc-siRNA. After 48hr incubation, cells may be harvested for RNA extraction. Total RNA may be extracted using RNeasy Kit following the manufacturer’s instructions (Qiagen, Shanghai, China). After reverse transcription, real-time quantitative PCR may be performed using an ABI Prism 7900HT to detect the relative abundance of B4GALT1 mRNA normalized to the housekeeping gene GAPDH. The expression of the target gene in each test sample may be determined by relative quantitation using the comparative Ct (AACt) method. This method measures the Ct differences (ACt) between target gene and housekeeping gene. The formula is as follows: ACt = average Ct of B4GALT1 -average Ct of GAPDH, AACt=ACt (sample) - average ACt (untreated control), relative expression of target gene mRNA = 2' ^AACt .

[00293] Alternatively or in addition, inhibition of expression of the B4GALT1 gene may be characterized by a reduction of mean relative expression of the B4GALT1 gene.

[00294] In some embodiments, when cells are transfected with 0. 1 nM of the nucleic acid of the invention, the mean relative expression of B4GALT1 is below 1, 0.9, 0.8, 0.7, 0.6, 0.5, or 0.4, preferably when determined by qPCR, more preferably by reverse transcriptase (RT)- qPCR, as described herein.

[00295] In some embodiments, when cells are transfected with 5 nM of the nucleic acid of the invention, the mean relative expression of B4GALT1 is below 1, 0.9, 0.8, 0.7, 0.6, 0.5, 0.4, 0.3 or 0.2, preferably when determined by qPCR, more preferably by reverse transcriptase (RT)-qPCR, as described herein.

[00296] Mean relative expression of the B4GALT1 gene may be quantified by the following method:

Huh7 cells (human hepatocyte-derived cell line, obtained from JCRB Cell Bank) may be maintained in Dulbecco’s Modified Eagle Medium (DMEM) supplemented with 10% FBS at 37°C in at atmosphere of 5% CO2. Cells may be transfected with siRNA duplexes targeting B4GALT1 mRNA or a negative control siRNA (siRNA-control; sense strand 5’- UUCUCCGAACGUGUCACGUTT-3’ (SEQ ID NO:934), antisense strand 5’- ACGUGACACGUUCGGAGAATT-3’ (SEQ ID NO:933)) at a final duplex concentration of 5 nM and 0.1 nM. Transfection may be carried out by adding 9.7 μL Opti-MEM (ThermoFisher) plus 0.3 μL Lipofectamine RNAiMAX (ThermoFisher) to 10 μL of each siRNA duplex. The mixture may be incubated at room temperature for 15 minutes before being added to 100 μL of complete growth medium containing 20,000 Huh7 cells. Cells may be incubated for 24 hours at 37°C/5% CO2 prior to total RNA purification using a RNeasy 96 Kit (Qiagen). Each duplex may be tested by transfection in duplicate wells in two independent experiments. cDNA synthesis may be performed using FastQuant RT (with gDNase) Kit (Tiangen). Realtime quantitative PCR (qPCR) may be performed on an ABI Prism 7900HT or ABI QuantStudio 7 with primers specific for human B4GALT1 (Hs00155245_ml) and human GAPDH (Hs02786624_gl) using a TaqMan Gene Expression Assay Kit (ThermoFisher Scientific). qPCR may be performed in duplicate on cDNA derived from each well and the mean Ct calculated. Relative B4GALT1 expression may be calculated from mean Ct values using the comparative Ct (AACt) method, normalised to GAPDH and relative to untreated cells.

[00297] Inhibition of the expression of B4GALT1 gene may be manifested by a reduction of the amount of mRNA of the target B4GALT1 gene in comparison to a suitable control.

[00298] In other embodiments, inhibition of the expression of B4GALT1 gene may be assessed in terms of a reduction of a parameter that is functionally linked to gene expression, e.g , protein expression or signaling pathways.

Conjugation of Tether 2 to a siRNA strand: TriGalNAc tether 2 (GalNAc-T2) conjugation at 5’-end or 3’-end

5’-GalNAc-T2 conjugates [00358] Preparation of TriGalNAc tether 2 NHS ester: To a solution of carboxylic acid tether 2 (compound 15, 227 mg, 121 pmol) in DMF (2.1 mL), N-hydroxysuccinimide (NHS) (15.3 mg, 133 pmol) and N,N'-diisopropylcarbodiimide (DIC) (19.7 μL, 127 pmol) were added. The solution was stirred at room temperature for 18 h and used without purification for the subsequent conjugation reactions.

[00359] General procedure for triGalNAc tether 2 conjugation: Amine-modified single strand was dissolved at 700 OD/mL in 50 mM carbonate/bicarbonate buffer pH 9.6/DMSO 4:6 (v/v) and to this solution was added one molar equivalent of Tether 2 NHS ester (57 mM) solution in DMF. The reaction was carried out at room temperature and after 1 h another molar equivalent of the NHS ester solution was added. The reaction was allowed to proceed for one more hour and reaction progress was monitored by LCMS. At least two molar equivalent excess of the NHS ester reagent relative to the amino modified oligonucleoside were needed to achieve quantitative consumption of the starting material. The reaction mixture was diluted 15-fold with water, filtered once through 1.2 μm filter from Sartorius and then purified by reserve phase (RP HPLC) on an Akta Pure (GE Healthcare) instrument.

[00360] The purification was performed using a XBridge C18 Prep 19 x 50 mm column from Waters. Buffer A was 100 mM TEAA pH 7 and buffer B contained 95% acetonitrile in buffer A. A flow rate of 10 mL/min and a temperature of 60°C were employed. UV traces at 280 nm were recorded. A gradient of 0-100% B within 60 column volumes was employed.

[00361] Fractions containing full-length conjugated oligonucleosides were pooled together, precipitated in the freezer with 3 M NaOAc, pH 5.2 and 85% ethanol and then dissolved at 1000 OD/mL in water. The O-acetates were removed with 20% ammonium hydroxide in water until completion (monitored by LC-MS).

[00362] The conjugates were desalted by size exclusion chromatography using Sephadex G25 Fine resin (GE Healthcare) on an Akta Pure (GE Healthcare) instrument to yield the conjugated oligonucleotides in an isolated yield of 60-80%.

[00363] The conjugates were characterized by HPLC-MS analysis with a 2.1 x 50 mm XBridge C18 column (Waters) on a Dionex Ultimate 3000 (Thermo Fisher Scientific) HPLC system equipped with a Compact ESLQq-TOF mass spectrometer (Bruker Daltonics). Buffer A was 16.3 mM triethylamine, 100 mM HFIP in 1% MeOH in H2O and buffer B contained 95% MeOH in buffer A. A flow rate of 250 μL/min and a temperature of 60°C were employed. UV traces at 260 and 280 nm were recorded. A gradient of 1-100% B within 31 min was employed.

[00364] The following schemes further set out the routes of synthesis:

Scheme 6 Scheme 7:

Scheme 8: Scheme 9: Example 4: Duplex Annealing

[00365] To generate the desired siRNA duplex, the two complementary strands were annealed by combining equimolar aqueous solutions of both strands. The mixtures were placed into a water bath at 70°C for 5 minutes and subsequently allowed to cool to ambient temperature within 2 h. The duplexes were lyophilized for 2 days and stored at -20°C.

[00366] The duplexes were analyzed by analytical SEC HPLC on Superdex™ 75 Increase 5/150 GL column 5 x 153-158 mm (Cytiva) on a Dionex Ultimate 3000 (Thermo Fisher Scientific) HPLC system. Mobile phase consisted of lx PBS containing 10% acetonitrile. An isocratic gradient was run in 10 min at a flow rate of 1.5 mL/min at room temperature. UV traces at 260 and 280 nm were recorded. Water (LC-MS grade) was purchased from Sigma- Aldrich and Phosphate-buffered saline (PBS; 10x, pH 7.4) was purchased from GIBCO (Thermo Fisher Scientific).

Conjugation conditions

[00367] Pre-activation: To a solution of compound 15 (16 umol, 4 eq.) in DMF (160 μL) was added TFA-O-PFP (15 l, 21 eq.) followed by DIPEA (23 pl, 32 eq.) at 25°C. The tube was shaken for 2 h at 25°C. The reaction was quenched with H2O (10 μL).

[00368] Coupling: The resulting mixture was diluted with DMF (400 pl), followed by addition of oligo-amine solution (4.0 pmol in 10 x PBS, pH 7.4, 500 μL; final oligo concentration in organic and aqueous solution: 4 pmol/ml = 4 mM). The tube was shaken at 25°C for 16 h and the reaction was analysed by LCMS. The resulting mixture was treated with 28% NH4OH (4.5 ml) and shaken for 2 h at 25°C. The mixture was analysed by LCMS, concentrated, and purified by IP-RP HPLC to produce the oligonucleotides conjugated to tether 2 GalNAc.

[00403] Huh7 cells (human hepatocyte-derived cell line, obtained from JCRB Cell Bank) were maintained in Dulbecco’s Modified Eagle Medium (DMEM) supplemented with 10% FBS at 37°C in at atmosphere of 5% CO2. Cells were transfected with siRNA duplexes targeting B4GALT1 mRNA or a negative control siRNA (siRNA-control; sense strand 5’- UUCUCCGAACGUGUCACGUTT-3 (SEQ ID NO:934)’, antisense strand 5’- ACGUGACACGUUCGGAGAATT-3’ (SEQ ID NO:933)) at a final duplex concentration of 5 nM and 0.1 nM. Transfection was carried out by adding 9.7 μL Opti-MEM (ThermoFisher) plus 0.3 μL Lipofectamine RNAiMAX (ThermoFisher) to 10 μL of each siRNA duplex. The mixture was incubated at room temperature for 15 minutes before being added to 100 μL of complete growth medium containing 20,000 Huh7 cells. Cells were incubated for 24 hours at 37°C/5% CO2 prior to total RNA purification using a RNeasy 96 Kit (Qiagen). Each duplex was tested by transfection in duplicate wells in two independent experiments.

[00404] cDNA synthesis was performed using FastQuant RT (with gDNase) Kit (Tiangen). Real-time quantitative PCR (qPCR) was performed on an ABI Prism 7900HT or ABI QuantStudio 7 with primers specific for human B4GALT1 and human GAPDH (Hs02786624_gl) using FastStart Universal Probe Master Kit (Roche).

[00405] qPCR was performed in duplicate on cDNA derived from each well and the mean Ct calculated. Relative B4GALT1 expression was calculated from mean Ct values using the comparative Ct (AACt) method, normalised to GAPDH and relative to untreated cells. Based on the results of primary screen, siRNA duplexes displaying good activity were selected for dose-response follow-up. Results are shown in Figures 9 and 10. Sequences of RNAi molecules are depicted in Table 5.

Example 11: Dose-response for Inhibition of B4GALT1 in Human Huh7 Cells

[00409] Huh7 cells (human hepatocyte-derived cell line, obtained from JCRB Cell Bank) were maintained in Dulbecco’s Modified Eagle Medium (DMEM) supplemented with 10% FBS at 37°C in at atmosphere of 5% CO2. Cells were transfected with siRNA duplexes designed against the target or a negative control siRNA at O.lnM and InM. Transfection was carried out by adding 9.7 μL Opti-MEM (ThermoFisher) plus 0.3 μL Lipofectamine RNAiMAX (ThermoFisher) to 10 μL of each siRNA duplex. The mixture was incubated at room temperature for 15 minutes before being added to 100 μL of complete growth medium containing 20,000 Huh7 cells. Cells were incubated for 24 hours at 37°C/5% CO2 prior to total RNA purification using a RNeasy 96 Kit (Qiagen). Each duplex was tested by transfection in duplicate wells and the experiment was repeated three time.

[00410] cDNA synthesis was performed using FastKing RT kit (with gDNase) Kit (Tiangen). Real-time quantitative PCR (qPCR) was performed on an ABI Prism 7900HT or ABI QuantStudio 7 with primers specific for human B4GALT1 (Hs00155245_ml) and human GAPDH (Hs02786624_gl) using a TaqMan Gene Expression Assay Kit (ThermoFisher Scientific).

[00411] qPCR was performed in duplicate on cDNA derived from each well and the mean Ct calculated. Relative target expression was calculated from mean Ct values using the comparative Ct (AACt) method, normalised to GAPDH and relative to untreated cells.

[00413] In a second experiment, the siRNA duplexes ETXM1203, ETXM1204, ETXM1218, ETXM1772, ETXM1773, ETXM1774, ETXM1775, ETXM1776, ETXM1777 and ETXM1778 were tested for inhibition of B4GALTl(Fig.l4).

Example 12: B4GALT1 pharmacology study

[00414] ETX in-house computational biology analysis identified B4GALT1, encoding beta-1, 4- galactosyltransferase 1, as a gene associated with Type 2 Diabetes (T2D). Here, the inventors establish B4GALT1 as a potential therapeutic target for T2D. In-silico--designed GalNAc- siRNAs targeting mouse hepatic B4GALT1 were synthesized and tested to access the plausibility of the hypothesis that a significant knockdown of hepatic B4GALT1 mRNA lowers the plasma levels of LDL-c, fibrinogen, and fasting glucose.

[00415] In vitro dose-response assay to select potent molecules

In vitro dose-response assay measuring the gene knockdown in primary mouse hepatocytes (PMHs) was performed to test 20 GalNAc-siRNAs targeting hepatic B4GALT1. Primary C57BL/6 mouse hepatocytes (PMHs) were isolated fresh by two-step collagenase liver perfusion. Cells were maintained in DMEM (Gibco-11995-092) supplemented with FBS, Penicillin/Streptomycin, HEPES and L-glutamine. Cells were cultured at 37°C in an atmosphere with 5% CO2 in a humidified incubator. Within 2 hours post isolation, PMHs were seeded at a density of 36,000 cells/well in regular 96-well tissue culture plates. Dose response analysis in PMHs was done by direct incubation of cells in a gymnotic free uptake setting with final GalNAc-siRNA concentrations of 1000, 500, 250, 125, 62.5, 31.3, 15.6, 7.8, 3.9, 1.95 nM. In control wells, cells were incubated without GalNAc-siRNA. After 48hr incubation, cells were harvested for RNA extraction. Total RNA was extracted using RNeasy Kit following the manufacturer’s instructions (Qiagen, Shanghai, China). After reverse transcription, real-time quantitative PCR was performed using an ABI Prism 7900HT to detect the relative abundance of B4GALT1 mRNA normalized to the housekeeping gene GAPDH. The expression of the target gene in each test sample was determined by relative quantitation using the comparative Ct (AACt) method. This method measures the Ct differences (ACt) between target gene and housekeeping gene. The formula is as follows: ACt = average Ct of B4GALT1 -average Ct of GAPDH, AACt=ACt (sample) - average ACt (untreated control), relative expression of target gene mRNA = 2' ^AACt . Based on the results of in vitro free uptake experiment, GalNAc-siRNAs displaying good activity were selected for EC50 determination using a 10-point concentration curve (Figure 15).

[00416] In vivo pharmacology with four selected GalNAc-siRNAs

The pharmacodynamic activity of four selected B4GALT1 GalNAc-siRNAs was measured in vivo. Twelve C57BL/6 male mice were allocated for each of GalNAc-siRNAs, ETXM619, ETXM624, ETXM628 and ETXM633. 5 mice were allocated as no-treatment control group. Mice were subcutaneously dosed with ETXMs (10 mg/kg) on day 0, defined as the day mice were first dosed, day 3 and day 7. 3 mice in each treatment group were sacrificed on day 3, day 7, day 10 and day 14. Upon termination, liver tissues and plasma samples were harvested for further analysis. Day 3 samples were used to evaluate the single dose effect of ETXMs given on day 0. Day 7 samples represent the repeat dose effect of ETXMs given on day 0 and day3. Likewise, day 10 and day 14 samples represent the repeat dose effect of ETXMs given on day 0, day 3 and day 7. 5 mice allocated as the control group were sacrificed on day 14.

[00417] B4GALT1 gene knockdown in mouse liver

Harvested liver samples were used to measure the B4GALT1 mRNA knockdown level by RT-qPCR. Upon collection, each tissue was treated with RNAlater and stored at 4°C overnight then at -80°C until the further analysis. Liver tissues were homogenized with TRIZOL for RNA extraction. RNA samples, adjusted to 400 ng/μL, were reverse transcribed to cDNA using FastKing RT Kit, manufactured by TIANGEN. After gDNA removal procedure, purified cDNA samples were used for RT-qPCR. RT-qPCR method and the relative mRNA expression calculations are as described above. Figure 16 shows that all test articles exhibit > 50% gene knockdown efficiency at day 3, 7, 10 and 14.

[00418] Terminal plasma collection and measurement of plasma biomarkers using biochemical analyser

The terminal plasma samples were collected via submandibular vein after 4-5 hour fasting. Blood samples were collected in heparin sodium coated tubes then centrifuged at 7,000g at 4°C for 10 min to obtain plasma samples. The plasma samples were used for the measurements of AST, ALT, albumin, ALP, BUN, CREA, TBIL, glucose, total cholesterol, LDL-c, HDL-c, triglycerides and NEFA (free fatty acids) by a biochemical analyser.

[00419] Measurement of plasma insulin and fibrinogen levels using ELISA kits

Blood samples were collected in K2EDTA coated tubes then centrifuged at 7,000g at 4°C for 10 minutes to obtain plasma samples. The plasma insulin level was measured using Mouse Insulin ELISA kit (Mercodia, 10-1247-01) according to the manufacturer’s protocol. The fibrinogen plasma level was measured using Mouse Fibrinogen Antigen Assay kit (Innovative Research, IMSFBGKTT).

[00420] B4GALT1 gene silence effect in biomarker modulation

The means of the untreated control group (n=5) and the day-14 treatment group comprising groups administered with ETXM619, ETXM624, ETXM628 or ETXM633 subcutaneously at day 0, day 3 and day7 (n=3 per group, n=12 total) were tested for equality under the null hypothesis via a two-tailed t-test. Statistically significant differences in the means of efficacy biomarker readouts were detected with an 18.8% decrease in LDL-C (p<0.05); a 21.0% decrease in fasting glucose (p<0.05); and a 29.6% decrease in fibrinogen (p<0.01 ) (Figure 17).
