The instant application contains a replacement Sequence Listing which has been submitted electronically in ASCII format and is hereby incorporated by reference in its entirety. Said ASCII copy, created on Mar. 11, 2020 is named 2057_1044US371_SL and is 6,706,780 bytes in size.

The present invention relates to compositions, methods and processes for the design, preparation, manufacture, use and/or formulation of AAV particles comprising modulatory polynucleotides, e.g., polynucleotides encoding small interfering RNA (siRNA) molecules which target the Huntingtin (HTT) gene (e.g., the wild-type or the mutated CAG-expanded HTT gene). Targeting of the mutated HTT gene may interfere with the HTT gene expression and the resultant HTT protein production. The AAV particles comprising modulatory polynucleotides encoding the siRNA molecules may be inserted into recombinant adeno-associated virus (AAV) vectors. Methods for using the AAV particles to inhibit the HTT gene expression in a subject with a neurodegenerative disease (e.g., Huntington's Disease (HD)) are also disclosed.

Huntington's Disease (HD) is a monogenic fatal neurodegenerative disease characterized by progressive chorea, neuropsychiatric and cognitive dysfunction. Huntington's Disease is known to be caused by an autosomal dominant triplet (CAG) repeat expansion which encodes poly-glutamine in the N-terminus of the huntingtin (HTT) protein. This repeat expansion results in a toxic gain of function of HTT and ultimately leads to striatal neurodegeneration which progresses to widespread brain atrophy. Symptoms typically appear between the ages of 35-44 and life expectancy subsequent to onset is 10-25 years. Interestingly, the length of the HTT expansion correlates with both age of onset and rate of disease progression, with longer expansions linked to greater severity of disease. In a small percentage of the HD population (˜6%), disease onset occurs from 2-20 years of age with appearance of an akinetic-rigid syndrome. These cases tend to progress faster than those of the later onset variety and have been classified as juvenile or Westphal variant HD. It is estimated that approximately 35,000-70,000 patients are currently suffering from HD in the US and Europe. Currently, only symptomatic relief and supportive therapies are available for treatment of HD, with a cure yet to be identified. Ultimately, individuals with HD succumb to other diseases (e.g., pneumonia, heart failure), choking, suffocation or other complications such as physical injury from falls.

The mechanisms by which CAG-expanded HTT results in neurotoxicity are not well understood. Huntingtin protein is expressed in all cells, though its concentration is highest in the brain. The normal function of HTT is unknown, but in the brains of HD patients, HTT aggregates into abnormal nuclear inclusions. It is now believed that it is this process of misfolding and aggregating along with the associated protein intermediates (i.e. the soluble species and toxic N-terminal fragments) that result in neurotoxicity.

Studies in animal models of HD have suggested that phenotypic reversal is feasible, for example, subsequent to gene shut off in regulated-expression models. Further, animal models in which silencing of HTT was tested, demonstrated promising results with the therapy being both well tolerated and showing potential therapeutic benefit. These findings indicate that HTT silencing may serve as a potential therapeutic target for treatment of HD.

The adeno-associated virus (AAV) is a member of the parvovirus family and has emerged as an attractive vector for gene therapy in large part because this virus is apparently non-pathogenic; in fact, AAV has not been associated with any human disease. Further appeal is due to its ability to transduce dividing and non-diving cells (including efficient transduction of neurons), diminished proinflammatory and immune responses in humans, its inability to autonomously replicate without a helper virus (AAV is a helper-dependent DNA parvovirus which belongs to the genus Dependovirus), and its long-term gene expression. Although over 10 recombinant AAV serotypes (rAAV) have been engineered into vectors, rAAV2 is the most frequently employed serotype for gene therapy trials. Additional rAAV serotypes have been developed and tested in animal models that are more efficient at neuronal transduction.

The present invention develops an AAV particle comprising modulatory polynucleotides encoding novel double stranded RNA (dsRNA) constructs and siRNA constructs and methods of their design, to inhibit or prevent the expression of CAG-expanded HTT in HD patients for treatment of the disease.

Described herein are methods, processes, compositions kits and devices for the administration of AAV particles comprising modulatory polynucleotides encoding siRNA molecules for the treatment, prophylaxis, palliation and/or amelioration of Huntington's Disease (HD) related symptoms and disorders.

I. Compositions of the Invention

According to the present invention, compositions for delivering modulatory polynucleotides and/or modulatory polynucleotide-based compositions by adeno-associated viruses (AAVs) are provided, AAV particles of the invention may be provided via any of several routes of administration, to a cell, tissue, organ, or organism, in vivo, ex vivo or in vitro.

As used herein, an “AAV particle” is a virus which comprises a viral genome with at least one payload region and at least one inverted terminal repeat (ITR) region.

As used herein, “viral genome” or “vector genome” or “viral vector” refers to the nucleic acid sequence(s) encapsulated in an AAV particle. Viral genomes comprise at least one payload region encoding polypeptides or fragments thereof.

As used herein, a “payload” or “payload region” is any nucleic acid molecule which encodes one or more polypeptides of the invention. At a minimum, a payload region comprises nucleic acid sequences that encode a sense and antisense sequence, an siRNA-based composition, or a fragment thereof, but may also optionally comprise one or more functional or regulatory elements to facilitate transcriptional expression and/or polypeptide translation.

The nucleic acid sequences and polypeptides disclosed herein may be engineered to contain modular elements and/or sequence motifs assembled to enable expression of the modulatory polynucleotides and/or modulatory polynucleotide-based compositions of the invention. In some embodiments, the nucleic acid sequence comprising the payload region may comprise one or more of a promoter region, an intron, a Kozak sequence, an enhancer or a polyadenylation sequence. Payload regions of the invention typically encode at least one sense and antisense sequence, an siRNA-based compositions, or fragments of the foregoing in combination with each other or in combination with other polypeptide moieties.

The payload regions of the invention may be delivered to one or more target cells, tissues, organs or organisms within the viral genome of an AAV particle.

Adeno-Associated Viruses (AAVs) and AAV Particles

Viruses of the Parvoviridae family are small non-enveloped icosahedral capsid viruses characterized by a single stranded DNA genome. Parvoviridae family viruses consist of two subfamilies: Parvovirinae, which infect vertebrates, and Densovirinae, which infect invertebrates. Due to its relatively simple structure, easily manipulated using standard molecular biology techniques, this virus family is useful as a biological tool. The genome of the virus may be modified to contain a minimum of components for the assembly of a functional recombinant virus, or viral particle, which is loaded with or engineered to express or deliver a desired payload, which may be delivered to a target cell, tissue, organ, or organism.

The parvoviruses and other members of the Parvoviridae family are generally described in Kenneth I. Berns, “Parvoviridae: The Viruses and Their Replication,” Chapter 69 in FIELDS VIROLOGY (3d Ed. 1996), the contents of which are incorporated by reference in their entirety.

The Parvoviridae family comprises the Dependovirus genus which includes adeno-associated viruses (AAV) capable of replication in vertebrate hosts including, but not limited to, human, primate, bovine, canine, equine, and ovine species.

The AAV viral genome is a linear, single-stranded DNA (ssDNA) molecule approximately 5,000 nucleotides (nt) in length. The AAV viral genome can comprise a payload region and at least one inverted terminal repeat (ITR) or ITR region. ITRs traditionally flank the coding nucleotide sequences for the non-structural proteins (encoded by Rep genes) and the structural proteins (encoded by capsid genes or Cap genes). While not wishing to be bound by theory, an AAV viral genome typically comprises two ITR sequences. The AAV viral genome comprises a characteristic T-shaped hairpin structure defined by the self-complementary terminal 145 nt of the 5′ and 3′ ends of the ssDNA which form an energetically stable double stranded region. The double stranded hairpin structures comprise multiple functions including, but not limited to, acting as an origin for DNA replication by functioning as primers for the endogenous DNA polymerase complex of the host viral replication cell.

In addition to the encoded heterologous payload, AAV vectors may comprise the viral genome, in whole or in part, of any naturally occurring and/or recombinant AAV serotype nucleotide sequence or variant, AAV variants may have sequences of significant homology at the nucleic acid (genome or capsid) and amino acid levels (capsids), to produce constructs which are generally physical and functional equivalents, replicate by similar mechanisms, and assemble by similar mechanisms. Chiorini et al., J. Vir. 71: 6823-33(1997); Srivastava et al., J. Vir. 45:555-64 (1983); Chiorini et al., J. Vir. 73:1309-1319 (1999); Rutledge et al., J. Vir. 72:309-319 (1998); and Wu et al., J. Vir. 74: 8635-47 (2000), the contents of each of which are incorporated herein by reference in their entirety.

In one embodiment, AAV particles of the present invention are recombinant AAV vectors which are replication defective, lacking sequences encoding functional Rep and Cap proteins within their viral genome. These defective AAV vectors may lack most or all parental coding sequences and essentially carry only one or two AAV ITR sequences and the nucleic acid of interest for delivery to a cell, a tissue, an organ or an organism.

In one embodiment, the viral genome of the AAV particles of the present invention comprise at least one control element which provides for the replication, transcription and translation of a coding sequence encoded therein. Not all of the control elements need always be present as long as the coding sequence is capable of being replicated, transcribed and/or translated in an appropriate host cell. Non-limiting examples of expression control elements include sequences for transcription initiation and/or termination, promoter and/or enhancer sequences, efficient RNA processing signals such as splicing and polyadenylation signals, sequences that stabilize cytoplasmic mRNA, sequences that enhance translation efficacy (e.g., Kozak consensus sequence), sequences that enhance protein stability, and/or sequences that enhance protein processing and/or secretion.

According to the present invention, AAV particles for use in therapeutics and/or diagnostics comprise a virus that has been distilled or reduced to the minimum components necessary for transduction of a nucleic acid payload or cargo of interest. In this manner, AAV particles are engineered as vehicles for specific delivery while lacking the deleterious replication and/or integration features found in wild-type viruses.

AAV vectors of the present invention may be produced recombinantly and may be based on adeno-associated virus (AAV) parent or reference sequences. As used herein, a “vector” is any molecule or moiety which transports, transduces or otherwise acts as a carrier of a heterologous molecule such as the nucleic acids described herein.

In addition to single stranded AAV viral genomes (e.g., ssAAVs), the present invention also provides for self-complementary AAV (scAAVs) viral genomes. scAAV viral genomes contain DNA strands which anneal together to form double stranded DNA. By skipping second strand synthesis, scAAVs allow for rapid expression in the cell.

In one embodiment, the AAV particle of the present invention is an scAAV.

In one embodiment, the AAV particle of the present invention is an ssAAV.

Methods for producing and/or modifying AAV particles are disclosed in the art such as pseudotyped AAV vectors (PCT Patent Publication Nos. WO200028004; WO200123001; WO2004112727; WO 2005005610 and WO 2005072364, the content of each of which is incorporated herein by reference in its entirety).

AAV particles may be modified to enhance the efficiency of delivery. Such modified AAV particles can be packaged efficiently and be used to successfully infect the target cells at high frequency and with minimal toxicity. In some embodiments the capsids of the AAV particles are engineered according to the methods described in US Publication Number US 20130195801, the contents of which are incorporated herein by reference in their entirety.

In one embodiment, the AAV particles comprising a payload region encoding the polypeptides of the invention may be introduced into mammalian cells.

Viral Genome Component: Untranslated Regions (UTRs)

By definition, wild type untranslated regions (UTRs) of a gene are transcribed but not translated. Generally, the 5′ UTR starts at the transcription start site and ends at the start codon and the 3′ UTR starts immediately following the stop codon and continues until the termination signal for transcription.

Features typically found in abundantly expressed genes of specific target organs may be engineered into UTRs to enhance the stability and protein production. As a non-limiting example, a 5′ UTR from mRNA normally expressed in the liver (e.g., albumin, serum amyloid A, Apolipoprotein A/B/E, transferrin, alpha fetoprotein, erythropoietin, or Factor VIII) may be used in the viral genomes of the AAV particles of the invention to enhance expression in hepatic cell lines or liver.

While not wishing to be bound by theory, wild-type 5′ untranslated regions (UTRs) include features which play roles in translation initiation. Kozak sequences, which are commonly known to be involved in the process by which the ribosome initiates translation of many genes, are usually included in 5′ UTRs. Kozak sequences have the consensus CCR(A/G)CCAUGG, where R is a purine (adenine or guanine) three bases upstream of the start codon (ATG), which is followed by another ‘G’.

In one embodiment, the 5′UTR in the viral genome includes a Kozak sequence.

In one embodiment, the 5′UTR in the viral genome does not include a Kozak sequence.

While not wishing to be bound by theory, wild-type 3′ UTRs are known to have stretches of Adenosines and Uridines embedded therein. These AU rich signatures are particularly prevalent in genes with high rates of turnover. Based on their sequence features and functional properties, the AU rich elements (AREs) can be separated into three classes (Chen et al, 1995, the contents of which are herein incorporated by reference in its entirety): Class I AREs, such as, but not limited to, c-Myc and MyoD, contain several dispersed copies of an AUUUA motif within U-rich regions. Class II AREs, such as, but not limited to, GM-CSF and TNF-α, possess two or more overlapping UUAUUUA(U/A)(U/A) nonamers. Class III ARES, such as, but not limited to, c-Jun and Myogenin, are less well defined. These U rich regions do not contain an AUUUA motif. Most proteins binding to the AREs are known to destabilize the messenger, whereas members of the ELAV family, most notably HuR, have been documented to increase the stability of mRNA. HuR binds to AREs of all the three classes. Engineering the HuR specific binding sites into the 3′ UTR of nucleic acid molecules will lead to HuR binding and thus, stabilization of the message in vivo.

Introduction, removal or modification of 3′ UTR AU rich elements (AREs) can be used to modulate the stability of polynucleotides. When engineering specific polynucleotides, e.g., payload regions of viral genomes, one or more copies of an ARE can be introduced to make polynucleotides less stable and thereby curtail translation and decrease production of the resultant protein. Likewise, AREs can be identified and removed or mutated to increase the intracellular stability and thus increase translation and production of the resultant protein.

In one embodiment, the 3′ UTR of the viral genome may include an oligo(dT) sequence for templated addition of a poly-A tail.

In one embodiment, the viral genome may include at least one miRNA seed, binding site or full sequence, microRNAs (or miRNA or miR) are 19-25 nucleotide noncoding RNAs that bind to the sites of nucleic acid targets and down-regulate gene expression either by reducing nucleic acid molecule stability or by inhibiting translation. A microRNA sequence comprises a “seed” region, i.e., a sequence in the region of positions 2-8 of the mature microRNA, which sequence has perfect Watson-Crick complementarity to the miRNA target sequence of the nucleic acid.

In one embodiment, the viral genome may be engineered to include, alter or remove at least one miRNA binding site, sequence or seed region.

Any UTR from any gene known in the art may be incorporated into the viral genome of the AAV particle. These UTRs, or portions thereof, may be placed in the same orientation as in the gene from which they were selected or they may be altered in orientation or location. In one embodiment, the UTR used in the viral genome of the AAV particle may be inverted, shortened, lengthened, made with one or more other 5′ UTRs or 3′ UTRs known in the art. As used herein, the term “altered” as it relates to a UTR, means that the UTR has been changed in some way in relation to a reference sequence. For example, a 3′ or 5′ UTR may be altered relative to a wild type or native UTR by the change in orientation or location as taught above or may be altered by the inclusion of additional nucleotides, deletion of nucleotides, swapping or transposition of nucleotides.

In one embodiment, the viral genome of the AAV particle comprises at least one artificial UTRs which is not a variant of a wild type UTR

In one embodiment, the viral genome of the AAV particle comprises UTRs which have been selected from a family of transcripts whose proteins share a common function, structure, feature or property.

Viral Genome Component: Polyadenylation Sequence

In one embodiment, the AAV particle comprises a viral genome with a payload region comprising nucleic acid sequences encoding a siRNA, miRNA or other RNAi agent. In such an embodiment, a viral genome encoding more than one polypeptide may be replicated and packaged into a viral particle. A target cell transduced with a viral particle may express the encoded siRNA, miRNA or other RNAi agent inside a single cell.

Modulatory Polynucleotides

In one embodiment, modulatory polynucleotides, e.g., RNA or DNA molecules, may be used to treat neurodegenerative disease, in particular, Huntington's Disease (HD). As used herein, a “modulatory polynucleotide” is any nucleic acid sequence(s) which functions to modulate (either increase or decrease) the level or amount of a target gene, e.g., mRNA or protein levels.

In one embodiment, the modulatory polynucleotides may comprise at least one nucleic acid sequence encoding at least one siRNA molecule. The nucleic acids may, independently if there is more than one, encode 1, 2, 3, 4, 5, 6, 7, 8, 9, or more than 9 siRNA molecules.

In one embodiment, the molecular scaffold may be located downstream of a CMV promoter, fragment or variant thereof.

In one embodiment, the molecular scaffold may be located downstream of a CBA promoter, fragment or variant thereof.

In one embodiment, the molecular scaffold may be a natural pri-miRNA scaffold located downstream of a CMV promoter. As a non-limiting example, the natural pri-miRNA scaffold is derived from the human miR155 scaffold.

In one embodiment, the molecular scaffold may be a natural pri-miRNA scaffold located downstream of a CBA promoter.

In one embodiment, the selection of a molecular scaffold and modulatory polynucleotide is determined by a method of comparing modulatory polynucleotides in pri-miRNA (see e.g., the method described by Miniarikova et al. Design, Characterization, and Lead Selection of Therapeutic miRN 4 s Targeting Huntingtin for Development of Gene Therapy for Huntington's Disease . Molecular Therapy-Nucleic Acids (2016) 5, e297 and International Publication No. WO2016102664, the contents of each of which are herein incorporated by reference in their entireties). The modulatory polynucleotide may, but it not limited to, targeting exon 1, CAG repeats, SNP rs362331 in exon 50 and/or SNP rs362307 in exon 67. To evaluate the activities of the modulatory polynucleotides, the molecular scaffold used which may be used is a human pri-miRNA scaffold (e.g., miR1155 scaffold) and the promoter may be CMV. The activity may be determined in vitro using HEK293T cells and a reporter (e.g., Luciferase). For exon 1 targeting, the modulatory polynucleotide is determined to be efficient at HTT knockdown if the knockdown is 80% or greater. For CAG targeting, the modulatory polynucleotide is determined to be efficient at HTT knockdown if the knockdown is at least 60%. For SNP targeting, the modulatory polynucleotide is determined to be efficient at HTT knockdown if the knockdown is at least 60%. For allele selectivity for CAG repeats or SNP targeting the modulatory polynucleotides may comprise at least 1 substitution in order to improve allele selectivity. As a non-limiting example, substitution may be a G or C replaced with a T or corresponding U and A or T/U replaced by a C.

In order to evaluate the optimal molecular scaffold for the modulatory polynucleotide, the modulatory polynucleotide is used in pri-miRNA scaffolds with a CAG promoter. The constructs are co-transfected with a reporter (e.g., luciferase reporter) at 50 ng. Constructs with greater than 80% knockdown at 50 ng co-transfection are considered efficient. In one aspect, the constructs with strong guide-strand activity are preferred. The molecular scaffolds can be processed in HEK293T cells by NGS to determine guide-passenger ratios, and processing variability.

To evaluate the molecular scaffolds and modulatory polynucleotides in vivo the molecular scaffolds comprising the modulatory polynucleotides are packaged in AAV (e.g., the serotype may be AAV5 (see e.g., the method and constructs described in WO2015060722, the contents of which are herein incorporated by reference in their entirety)) and administered to an in vivo model (e.g., Hu128/21 HD mouse) and the guide-passenger ratios, 5′ and 3′ end processing, reversal of guide and passenger strands, and knockdown can be determined in different areas of the model.

In one embodiment, the selection of a molecular scaffold and modulatory polynucleotide is determined by a method of comparing modulatory polynucleotides in natural pri-miRNA and synthetic pri-miRNA. The modulatory polynucleotide may, but it not limited to, targeting an exon other than exon 1. To evaluate the activities of the modulatory polynucleotides, the molecular scaffold is used with a CBA promoter. In one aspect, the activity may be determined in vitro using HEK293T cells, HeLa cell and a reporter (e.g., Luciferase) and knockdown efficient modulatory polynucleotides showed HTT knockdown of at least 80% in the cell tested. Additionally, the modulatory polynucleotides which are considered most efficient showed low to no significant passenger strand (p-strand) activity. In another aspect, the endogenous HTT knockdown efficacy is evaluated by transfection in vitro using HEK293T cells, HeLa cell and a reporter. Efficient modulatory polynucleotides show greater than 50% endogenous HTT knockdown. In yet another aspect, the endogenous HTT knockdown efficacy is evaluated in different cell types (e.g., HEK293, HeLa, primary astrocytes. U251 astrocytes, SH-SY5Y neuron cells and fibroblasts from HD patients) by infection (e.g., AAV2). Efficient modulatory polynucleotides show greater than 60% endogenous HTT knockdown.

To evaluate the molecular scaffolds and modulatory polynucleotides in vivo the molecular scaffolds comprising the modulatory polynucleotides are packaged in AAV and administered to an in vivo model (e.g., YAC128 HD mouse) and the guide-passenger ratios, 5′ and 3′ end processing, ratio of guide to passenger strands, and knockdown can be determined in different areas of the model (e.g., tissue regions). The molecular scaffolds can be processed from in vivo samples by NGS to determine guide-passenger ratios, and processing variability.

In one embodiment, the modulatory polynucleotide is designed using at least one of the following properties: loop variant, seed mismatch/bulge/wobble variant, stem mismatch, loop variant and vassal stem mismatch variant, seed mismatch and basal stem mismatch variant, stem mismatch and basal stem mismatch variant, seed wobble and basal stem wobble variant, or a stem sequence variant.

siRNA Molecules

The present invention relates to RNA interference (RNAi) induced inhibition of gene expression for treating neurodegenerative disorders. Provided herein are siRNA duplexes or encoded dsRNA that target the HTT gene (referred to herein collectively as “siRNA molecules”). Such siRNA duplexes or encoded dsRNA can reduce or silence HTT gene expression in cells, for example, medium spiny neurons, cortical neurons and/or astrocytes, thereby, ameliorating symptoms of Huntington's Disease (HD).

RNAi (also known as post-transcriptional gene silencing (PTGS), quelling, or co-suppression) is a post-transcriptional gene silencing process in which RNA molecules, in a sequence specific manner, inhibit gene expression, typically by causing the destruction of specific mRNA molecules. The active components of RNAi are short/small double stranded RNAs (dsRNAs), called small interfering RNAs (siRNAs), that typically contain 15-30 nucleotides (e.g., 19 to 25, 19 to 24 or 19-21 nucleotides) and 2 nucleotide 3′ overhangs and that match the nucleic acid sequence of the target gene. These short RNA species may be naturally produced in vivo by Dicer-mediated cleavage of larger dsRNAs and they are functional in mammalian cells.

Naturally expressed small RNA molecules, named microRNAs (miRNAs), elicit gene silencing by regulating the expression of mRNAs. The miRNAs containing RNA Induced Silencing Complex (RISC) targets mRNAs presenting a perfect sequence complementarity with nucleotides 2-7 in the 5′ region of the miRNA which is called the seed region, and other base pairs with its 3′ region, miRNA mediated down regulation of gene expression may be caused by cleavage of the target mRNAs, translational inhibition of the target mRNAs, or mRNA decay. miRNA targeting sequences are usually located in the 3′-UTR of the target mRNAs. A single miRNA may target more than 100 transcripts from various genes, and one mRNA may be targeted by different miRNAs.

siRNA duplexes or dsRNA targeting a specific mRNA may be designed and synthesized in vitro and introduced into cells for activating RNAi processes. Elbashir et al. demonstrated that 21-nucleotide siRNA duplexes (termed small interfering RNAs) were capable of effecting potent and specific gene knockdown without inducing immune response in mammalian cells (Elbashir S M et al., Nature, 2001, 411, 494-498). Since this initial report, post-transcriptional gene silencing by siRNAs quickly emerged as a powerful tool for genetic analysis in mammalian cells and has the potential to produce novel therapeutics.

RNAi molecules which were designed to target against a nucleic acid sequence that encodes poly-glutamine repeat proteins which cause poly-glutamine expansion diseases such as Huntington's Disease, are described in U.S. Pat. Nos. 9,169,483 and 9,181,544 and International Patent Publication No. WO2015179525, the content of each of which is herein incorporated by reference in their entirety. U.S. Pat. Nos. 9,169,483 and 9,181,544 and International Patent Publication No. WO2015179525 each provide isolated RNA duplexes comprising a first strand of RNA (e.g., 15 contiguous nucleotides) and second strand of RNA (e.g., complementary to at least 12 contiguous nucleotides of the first strand) where the RNA duplex is about 15 to 30 base pairs in length. The first strand of RNA and second strand of RNA may be operably linked by an RNA loop (˜4 to 50 nucleotides) to form a hairpin structure which may be inserted into an expression cassette. Non-limiting examples of loop portions include SEQ ID NO: 9-14 of U.S. Pat. No. 9,169,483, the content of which is herein incorporated by reference in its entirety. Non-limiting examples of strands of RNA which may be used, either full sequence or part of the sequence, to form RNA duplexes include SEQ ID NO: 1-8 of U.S. Pat. No. 9,169,483 and SEQ ID NO: 1-11, 33-59, 208-210, 213-215 and 218-221 of U.S. Pat. No. 9,181,544, the contents of each of which is herein incorporated by reference in its entirety. Non-limiting examples of RNAi molecules include SEQ ID NOs: 1-8 of U.S. Pat. No. 9,169,483, SEQ ID NOs: 1-11, 33-59, 208-210, 213-215 and 218-221 of U.S. Pat. No. 9,181,544 and SEQ ID NOs: 1, 6, 7, and 35-38 of International Patent Publication No. WO2015179525, the contents of each of which is herein incorporated by reference in their entirety.

In vitro synthesized siRNA molecules may be introduced into cells in order to activate RNAi. An exogenous siRNA duplex, when it is introduced into cells, similar to the endogenous dsRNAs, can be assembled to form the RNA Induced Silencing Complex (RISC), a multiunit complex that interacts with RNA sequences that are complementary to one of the two strands of the siRNA duplex (i.e., the antisense strand). During the process, the sense strand (or passenger strand) of the siRNA is lost from the complex, while the antisense strand (or guide strand) of the siRNA is matched with its complementary RNA. In particular, the targets of siRNA containing RISC complexes are mRNAs presenting a perfect sequence complementarity. Then, siRNA mediated gene silencing occurs by cleaving, releasing and degrading the target.

The siRNA duplex comprised of a sense strand homologous to the target mRNA and an antisense strand that is complementary to the target mRNA offers much more advantage in terms of efficiency for target RNA destruction compared to the use of the single strand (ss)-siRNAs (e.g. antisense strand RNA or antisense oligonucleotides). In many cases, it requires higher concentration of the ss-siRNA to achieve the effective gene silencing potency of the corresponding duplex.

Any of the foregoing molecules may be encoded by a viral genome.

Design and Sequences of siRNA Duplexes Targeting HTT Gene

The present invention provides small interfering RNA (siRNA) duplexes (and modulatory polynucleotides encoding them) that target HTT mRNA to interfere with HTT gene expression and/or HTT protein production.

The encoded siRNA duplex of the present invention contains an antisense strand and a sense strand hybridized together forming a duplex structure, wherein the antisense strand is complementary to the nucleic acid sequence of the targeted HTT gene, and wherein the sense strand is homologous to the nucleic acid sequence of the targeted HTT gene. In some aspects, the 5′ end of the antisense strand has a 5′ phosphate group and the 3′ end of the sense strand contains a 3′hydroxyl group. In other aspects, there are none, one or 2 nucleotide overhangs at the 3′end of each strand.

Some guidelines for designing siRNAs have been proposed in the art. These guidelines generally recommend generating a 19-nucleotide duplexed region, symmetric 2-3 nucleotide 3′overhangs, 5′-phosphate and 3′-hydroxyl groups targeting a region in the gene to be silenced. Other rules that may govern siRNA sequence preference include, but are not limited to, (i) A/U at the 5′ end of the antisense strand; (ii) G/C at the 5′ end of the sense strand; (iii) at least five A/U residues in the 5′ terminal one-third of the antisense strand; and (iv) the absence of any GC stretch of more than 9 nucleotides in length. In accordance with such consideration, together with the specific sequence of a target gene, highly effective siRNA molecules essential for suppressing mammalian target gene expression may be readily designed.

According to the present invention, siRNA molecules (e.g., siRNA duplexes or encoded dsRNA) that target the HTT gene are designed. Such siRNA molecules can specifically, suppress HTT gene expression and protein production. In some aspects, the siRNA molecules are designed and used to selectively “knock out” HTT gene variants in cells, i.e., mutated HTT transcripts that are identified in patients with HD disease. In some aspects, the siRNA molecules are designed and used to selectively “knock down” HTT gene variants in cells. In other aspects, the siRNA molecules are able to inhibit or suppress both the wild type and mutated HTT gene.

In one embodiment, an siRNA molecule of the present invention comprises a sense strand and a complementary antisense strand in which both strands are hybridized together to form a duplex structure. The antisense strand has sufficient complementarity to the HTT mRNA sequence to direct target-specific RNAi, i.e., the siRNA molecule has a sequence sufficient to trigger the destruction of the target mRNA by the RNAi machinery or process.

In one embodiment, an siRNA molecule of the present invention comprises a sense strand and a complementary antisense strand in which both strands are hybridized together to form a duplex structure and where the start site of the hybridization to the HTT mRNA is between nucleotide 100 and 7000 on the HTT mRNA sequence. As a non-limiting example, the start site may be between nucleotide 100-150, 150-200, 200-250, 250-300, 300-350, 350-400, 400-450, 450-500, 500-550, 550-600, 600-650, 650-700, 700-70, 750-800, 800-850, 850-900, 900-950, 950-1000, 1000-1050, 1050-1100, 1100-1150, 1150-1200, 1200-1250, 1250-1300, 1300-1350, 1350-1400, 1400-1450, 1450-1500, 1500-1550, 1550-1600, 1600-1650, 1650-1700, 1700-1750, 1750-1800, 1800-1850, 1850-1900, 1900-1950, 1950-2000, 2000-2050, 2050-2100, 2100-2150, 2150-2200, 2200-2250, 2250-2300, 2300-2350, 2350-2400, 2400-2450, 2450-2500, 2500-2550, 2550-2600, 2600-2650, 2650-2700, 2700-2750, 2750-2800, 2800-2850, 2850-2900, 2900-2950, 2950-3000, 3000-3050, 3050-3100, 3100-3150, 3150-3200, 3200-3250, 3250-3300, 3300-3350, 3350-3400, 3400-3450, 3450-3500, 3500-3550, 3550-3600, 3600-3650, 3650-3700, 3700-3750, 3750-3800, 3800-3850, 3850-3900, 3900-3950, 3950-4000, 4000-4050, 4050-4100, 4100-4150, 4150-4200, 4200-4250, 4250-4300, 4300-4350, 4350-4400, 4400-4450, 4450-4500, 4500-4550, 4550-4600, 4600-4650, 4650-4700, 4700-4750, 4750-4800, 4800-4850, 4850-4900, 4900-4950, 4950-5000, 5000-5050, 5050-5100, 5100-5150, 5150-5200, 5200-5250, 5250-5300, 5300-5350, 5350-5400, 5400-5450, 5450-5500, 5500-5550, 5550-5600, 5600-5650, 5650-5700, 5700-5750, 5750-5800, 5800-5850, 5850-5900, 5900-5950, 5950-6000, 6000-6050, 6050-6100, 6100-6150, 6150-6200, 6200-6250, 6250-6300, 6300-6350, 6350-6400, 6400-6450, 6450-6500, 6500-6550, 6550-6600, 6600-6650, 6650-6700, 6700-6750, 6750-6800, 6800-6850, 6850-6900, 6900-6950, 6950-7000, 7000-7050, 7050-7100, 7100-7150, 7150-7200, 7200-7250, 7250-7300, 7300-7350, 7350-7400, 7400-7450, 7450-7500, 7500-7550, 7550-7600, 7600-7650, 7650-7700, 7700-7750, 7750-7800, 7800-7850, 7850-7900, 7900-7950, 7950-8000, 8000-8050, 8050-8100, 8100-8150, 8150-8200, 8200-8250, 8250-8300, 8300-8350, 8350-8400, 8400-8450, 8450-8500, 8500-8550, 8550-8600, 8600-8650, 8650-8700, 8700-8750, 8750-8800, 8800-8850, 8850-8900, 8900-8950, 8950-9000, 9000-9050, 9050-9100, 9100-9150, 9150-9200, 9200-9250, 9250-9300, 9300-9350, 9350-9400, 9400-9450, 9450-9500, 9500-9550, 9550-9600, 9600-9650, 9650-9700, 9700-9750, 9750-9800, 9800-9850, 9850-9900, 9900-9950, 9950-10000, 10000-10050, 10050-10100, 10100-10150, 10150-10200, 10200-10250, 10250-10300, 10300-10350, 10350-10400, 10400-10450, 10450-10500, 10500-10550, 10550-10600, 10600-10650, 10650-10700, 10700-10750, 10750-10800, 10800-10850, 10850-10900, 10900-10950, 10950-11000, 11050-11100, 11100-11150, 11150-11200, 11200-11250, 11250-11300, 11300-11350, 11350-11400, 11400-11450, 11450-11500, 11500-11550, 11550-11600, 11600-11650, 11650-11700, 11700-11750, 11750-11800, 11800-11850, 11850-11900, 11900-11950, 11950-12000, 12000-12050, 12050-12100, 12100-12150, 12150-12200, 12200-12250, 12250-12300, 12300-12350, 12350-12400, 12400-12450, 12450-12500, 12500-12550, 12550-12600, 12600-12650, 12650-12700, 12700-12750, 12750-12800, 12800-12850, 12850-12900, 12900-12950, 12950-13000, 13050-13100, 13100-13150, 13150-13200, 13200-13250, 13250-13300, 13300-13350, 13350-13400, 13400-13450, and 13450-13500 on the HTT mRNA sequence.

siRNA Modification

In some embodiments, the siRNA molecules of the present invention, when not delivered as a precursor or DNA, may be chemically modified to modulate some features of RNA molecules, such as, but not limited to, increasing the stability of siRNAs in vivo. The chemically modified siRNA molecules can be used in human therapeutic applications, and are improved without compromising the RNAi activity of the siRNA molecules. As a non-limiting example, the siRNA molecules modified at both the 3′ and the 5′ end of both the sense strand and the antisense strand.

In some aspects, the siRNA duplexes of the present invention may contain one or more modified nucleotides such as, but not limited to, sugar modified nucleotides, nucleobase modifications and/or backbone modifications. In some aspects, the siRNA molecule may contain combined modifications, for example, combined nucleobase and backbone modifications.

In one embodiment, the modified nucleotide may be a sugar-modified nucleotide. Sugar modified nucleotides include, but are not limited to 2′-fluoro, 2′-amino and 2′-thio modified ribonucleotides, e.g. 2′-fluoro modified ribonucleotides. Modified nucleotides may be modified on the sugar moiety, as well as nucleotides having sugars or analogs thereof that are not ribosyl. For example, the sugar moieties may be, or be based on, mannoses, arabinoses, glucopyranoses, galactopyranoses, 4′-thioribose, and other sugars, heterocycles, or carbocycles.

In one embodiment, the modified nucleotide may be a nucleobase-modified nucleotide.

In one embodiment, the modified nucleotide may be a backbone-modified nucleotide. In some embodiments, the siRNA duplexes of the present invention may further comprise other modifications on the backbone. A normal “backbone”, as used herein, refers to the repeating alternating sugar-phosphate sequences in a DNA or RNA molecule. The deoxyribose/ribose sugars are joined at both the 3′-hydroxyl and 5′-hydroxyl groups to phosphate groups in ester links, also known as “phosphodiester” bonds/linker (PO linkage). The PO backbones may be modified as “phosphorothioate backbone (PS linkage). In some cases, the natural phosphodiester bonds may be replaced by amide bonds but the four atoms between two sugar units are kept. Such amide modifications can facilitate the solid phase synthesis of oligonucleotides and increase the thermodynamic stability of a duplex formed with siRNA complement. See e.g. Mesmaeker et al., Pure & Appl. Chem., 1997, 3, 437-440; the content of which is incorporated herein by reference in its entirety.

Modified bases refer to nucleotide bases such as, for example, adenine, guanine, cytosine, thymine, uracil, xanthine, inosine, and queuosine that have been modified by the replacement or addition of one or more atoms or groups. Some examples of modifications on the nucleobase moieties include, but are not limited to, alkylated, halogenated, thiolated, aminated, amidated, or acetylated bases, individually or in combination. More specific examples include, for example, 5-propynyluridine, 5-propynylcytidine, 6-methyladenine, 6-methylguanine, N,N,-dimethyladenine, 2-propyladenine, 2-propylguanine, 2-aminoadenine, 1-methylinosine, 3-methyluridine, 5-methylcytidine, 5-methyluridine and other nucleotides having a modification at the 5 position, 5-(2-amino)propyl uridine, 5-halocytidine, 5-halouridine, 4-acetylcytidine, 1-methyladenosine, 2-methyladenosine, 3-methylcytidine, 6-methyluridine, 2-methylguanosine, 7-methylguanosine, 2,2-dimethylguanosine, 5-methylaminoethyluridine, 5-methyloxyuridine, deazanucleotides such as 7-deaza-adenosine, 6-azouridine, 6-azocytidine, 6-azothymidine, 5-methyl-2-thiouridine, other thio bases such as 2-thiouridine and 4-thiouridine and 2-thiocytidine, dihydrouridine, pseudouridine, queuosine, archaeosine, naphthyl and substituted naphthyl groups, any O- and N-alkylated purines and pyrimidines such as N6-methyladenosine, 5-methylcarbonylmethyluridine, uridine 5-oxyacetic acid, pyridine-4-one, pyridine-2-one, phenyl and modified phenyl groups such as aminophenol or 2,4,6-trimethoxy benzene, modified cytosines that act as G-clamp nucleotides, 8-substituted adenines and guanines, 5-substituted uracils and thymines, azapyrimidines, carboxyhydroxyalkyl nucleotides, carboxyalkylaminoalkyl nucleotides, and alkylcarbonylalkylated nucleotides.

In one embodiment, the modified nucleotides may be on just the sense strand.

In another embodiment, the modified nucleotides may be on just the antisense strand.

In some embodiments, the modified nucleotides may be in both the sense and antisense strands.

In some embodiments, the chemically modified nucleotide does not affect the ability of the antisense strand to pair with the target mRNA sequence, such as the HTT mRNA sequence.

In one embodiment, the AAV particle comprising a nucleic acid sequence encoding the siRNA molecules of the present invention may encode siRNA molecules which are polycistronic molecules. The siRNA molecules may additionally comprise one or more linkers between regions of the siRNA molecules.

The antisense sequence, in some instances, comprises a “G” nucleotide at the 5′ most end. Non-limiting examples of antisense sequences, or fragments or variants thereof, which may be encoded by the modulatory polynucleotide are described in Table 2.

In other embodiments, the sense sequence may reside on the 3′ arm while the antisense sequence resides on the 5′ arm of the stem of the stem loop structure of the modulatory polynucleotide. Non-limiting examples of sense and antisense sequences which may be encoded by the modulatory polynucleotide are described in Tables 2 and 3.

In one embodiment, the sense and antisense sequences may be completely complementary across a substantial portion of their length. In other embodiments the sense sequence and antisense sequence may be at least 70, 80, 90, 95 or 99% complementarity across independently at least 50, 60, 70, 80, 85, 90, 95, or 99% of the length of the strands.

Neither the identity of the sense sequence nor the homology of the antisense sequence need to be 100% complementarity to the target sequence.

In one embodiment, separating the sense and antisense sequence of the stem loop structure of the modulatory polynucleotide is a loop sequence (also known as a loop motif, linker or linker motif). The loop sequence may be of any length, between 4-30 nucleotides, between 4-20 nucleotides, between 4-15 nucleotides, between 5-15 nucleotides, between 6-12 nucleotides, 6 nucleotides, 7 nucleotides, 8 nucleotides, 9 nucleotides, 10 nucleotides, 11 nucleotides, 12 nucleotides, 13 nucleotides, 14 nucleotides, and/or 15 nucleotides.

In some embodiments, the loop sequence comprises a nucleic acid sequence encoding at least one UGUG motif. In some embodiments, the nucleic acid sequence encoding the UGUG motif is located at the 5′ terminus of the loop sequence.

In one embodiment, spacer regions may be present in the modulatory polynucleotide to separate one or more modules (e.g., 5′ flanking region, loop motif region, 3′ flanking region, sense sequence, antisense sequence) from one another. There may be one or more such spacer regions present.

In one embodiment, the 5′ arm, sense and/or antisense sequence, loop motif and/or 3′ arm sequence may be altered (e.g., substituting 1 or more nucleotides, adding nucleotides and/or deleting nucleotides). The alteration may cause a beneficial change in the function of the construct (e.g., increase knock-down of the target sequence, reduce degradation of the construct, reduce off target effect, increase efficiency of the payload, and reduce degradation of the payload).

In one embodiment, the molecular scaffold of the modulatory polynucleotides is aligned in order to have the rate of excision of the guide strand (also referred to herein as the antisense strand) be greater than the rate of excision of the passenger strand (also referred to herein as the sense strand).
