DETAILED DESCRIPTION

Hepatitis B is a potentially life-threatening liver infection caused by the Hepatitis B virus (HBV). HBV infection is a global public health problem causing chronic liver infection and increasing the risk for liver cirrhosis and liver cancer. The WHO estimated that 296 million people worldwide with 1 million people in the U.S., were living with chronic hepatitis B infections in 2019, with 1.5 million new infections each year. In 2019, hepatitis B resulted in an estimated 820,000 deaths, mostly from cirrhosis and hepatocellular carcinoma (primary liver cancer).

HBV belongs to the Hepadnaviridae family, a family of small enveloped hepatotropic DNA viruses (Wei L. and Ploss A. Nature communications 12(1591) 1-13 (2021)). The HBV virion contains a compact, partially double-stranded, about 3.2 kb relaxed circular DNA (rcDNA) genome. The genome contains four lesions: a covalently linked HBV polymerase and a 10 nucleotide (nt) DNA flap on the 5′-end of the minus strand; and a 5′-capped RNA primer and single-stranded DNA (ssDNA) gap on the plus-strand. The HBV genome is an about 3.2 kilobase double-stranded DNA molecule, but can be longer or shorter depending on the particular HBV strain (e.g. up to 3300 bp or more in size). An exemplary HBV genome is the Hepatitis B Virus genome (Hepatitis B virus subtype ayw, complete genome, GenBank: U95551.1), SEQ ID NO: 650. At least 10 genotypes (A to J) have been identified with a divergence of no more than 8% between genotypes. Subgenotypes also exist including subgenotypes classified as HBV genotype A (A1-A7), genotype B (B1-B9), genotype C (C1-16), genotype D (D1-D8), and genotype F (F1-F4) (Zhang et al. World J Gastroenterol., 2015, 22:126-144). Within sub-genotypes the sequence identity divergence is only about 4%. It is understood that the provided systems and methods are applicable to a plurality of HBV genomes, particularly given the high sequence similarity. For purposes herein, reference to numbering of nucleotide positions is nucleotide (base pair) numbering of HBV DNA sequence described under GenBank accession no. U95551.1, set forth in SEQ ID NO:650. A skilled artisan understands that target site or base pair positions, such as described herein, in another HBV genome may not be at the identical position but nevertheless may be a homologous sequence or substantially homologous sequence (e.g. 1, 2 or 3 mismatches), such as determined by alignment of an HBV genome sequence with the sequence set forth in SEQ ID NO:650. A corresponding position or positions may thus be readily identified by alignment of an HBV genome sequence with the reference sequence set forth in SEQ ID NO:650. The Hepatitis B virus contains a circular genome and therefore for the purposes herein references to numbering of nucleotide positions of a linear HBV DNA sequence may shift by a few nucleotides, such as depending on the start of a linear sequence. For instance, the sequence set forth in SEQ ID NO:650 and SEQ ID NO: 1071 are the same sequence but the start of the linear sequences shifts by two nucleotides due to differences in the start of the linerar sequence. It is well within the level of a skilled artisan to identify corresponding sequence regions between and among different sequences of an HBV genome sequence.

The HBV lifecycle includes processes, such as viral entry, cccDNA formation, transcription, replication, assembly, secretion, and integration. Following viral entry into hepatocytes via the bile acid transporter NTCP11, the viral nucleocapsid harboring the HBV rcDNA is transported to the nucleus. The rcDNA is released, and the four lesions on the rcDNA are fully repaired to form a supercoiled cccDNA molecule (also called minichromosomes). The viral repair factors are dispensable for repair and the cccDNA often relies on host DNA repair machinery, including TDP2, DNA polymerase (POL) κ, POLα, DNA ligase 1 and 3, and flap endonuclease 1. The HBV hijacks host ubiquitous and liver-enriched transcription factors for cccDNA transcriptional regulation. The cccDNA is the key viral depot driving chronic HBV infection and serves as the template for all HBV viral transcripts. Another form of HBV DNA in the host is the stably integrated HBV DNA in the host genome (Zhao K., et al., Cell Press—The Innovation 1(2): 1-10 (2020). Double-stranded linear DNA (dslDNA) is the dominant substrate for integration into the host genome. As there is almost no sequence homology between the viral DNA and the cellular DNA, NHEJ DNA repair pathway is proposed as a mechanism for HBV DNA integration. HBV DNA integration occurs throughout the host genome at double stranded breaks, with terminal deletions up to 200 bp from the integrated HBV DNA being common No specific chromosomal hot-spots or common recurring sites have been observed between patients. There is some evidence for enrichment in particular genomic sites in tumour tissues (Sung W., et al., Nature Genetics 44(7):765-9 (2012)). Although no progeny virus is produced, integrated HBV DNA can produce viral RNAs and proteins. HBV DNA integration occurs more often in hepatic cancer cells (84%) than in normal liver tissues (30%).

Current standard of care includes nucleoside analogs (e.g., lamivudine) and PEGlyated interferon therapies. Nucleoside analogs act by inhibiting HBV polymerase activity resulting in a decrease in viral replication. However, prolonged treatment periods, increase in viral resistance and emergence of mutant strains, have reduced the effectiveness of nucleoside therapies (Papatheodoridis G. V. et al., Am. J. Gastroenterol 97(7):1618-28 (2002). PEGlyated interferon therapy either alone or in combination with nucleoside analogs (e g, lamivudine) has been tested to suppress transcription of viral DNA. PEGylated interferon therapy has been shown to mediate divergent effects on the innate and adaptive arms of the immune system, with strinkingly depleting effects on CD8 T cells, limiting the efficacy of the therapy (Micco L., et al., Journal of Hepatology 58(2): 225-233 (2013); Stelma F., et al., Journal f Infectious Disease 212(7):1042-51 (2015) marcellin P., et al., New England Journal of Medicine 351(12):1206-17 (2004)). Nucleotide analogs nor PEGylated therapies are able to clear or suppress production of HBV surface antigen (HBsAg), which has been linked to poor prognosis of HBV infection. Other therapies including antisense oligonucleotide (ASO) and siRNA approaches centered at reducing HBsAg to reach functional cures (Billioud G., et al., Journal of Hepatology 64(4):781-9 (2015); Gane E., et al., Hepatology 74(4):1795-1808 (2021); Flisiak R., et al., Expert Opinion on Biology Therapy 18(6)609-617) have shown to be promising in inhibiting HBsAg, HBeAg, and HBV DNA synthesis. However, the functional benefit of any of these therapies on the regeneration of liver tissue is unclear.

Current antiviral therapies rarely achieve a cure as they inhibit cytoplasmic HBV genome replication and do not directly target the cccDNA form-a form that serves as an HBV replication intermediate and viral persistence reservoir (Yang G., et al., Theranostics 9(24):7345-58 (2019)). Genome engineering approaches such as nucleases or base editors target removal or mutagenesis of the cccDNA pool in order to functionally cure the infection. However, such nuclease-based therapies have a chance of generating chromosomal abnormalities and therefore are not preferred, highlighting the need for better HBV therapeutics.

The persistence of the episomal cccDNA pool in infected hepatocytes remains a critical obstacle in complete elimination by anti-HBV therapies. The cccDNA accumulates in the nucleus as a chromatin-like cccDNA minichromosome assembled by histones and non-histones. The cccDNA shows unusual chromatin regulation due to its non-native status. For instance, changes the epigenetic states of the cccDNA have been found to dictate its transcriptional activity (Yang G., et al., Theranostics 9(24):7345-58 (2019). For example, the host nucleosome assembly machinery (HAT1/CAF-1) acetylates histone H4 at the sites of H4K5 and H4K12 contributing to the assembly of the cccDNA. The acetylation marks on the histones of the cccDNA in turn promote HBV replication and accumulation of the cccDNA. This transcriptional activity is largely driven by the presence of absence of activating epigenetic marks on the cccDNA; repressive histone marks (e.g., H3K27me3 and H3K9me3) are minute, suggesting that there is limited repression in the cccDNA (Tropberger P. et al., PNAS, 112(42):E5715-E5724 (2015), Riviere L., et al., J Hepatol 15(00450):S0168-8278 (2015)).

Desirable clinical outcomes have been associated with key epigenetic features within the cccDNA minichromosome. Studies have found that cccDNA contains methylation-prone CpG islands that are connected to the behavior of HBV (Zhang Y., et al., PlosOne 9(10):e110442 (2014), Vivekanandan P, et al., Journal of infectious diseases, 199(9):1286-1291 (2009), Vivekanandan P, et al., Journal of Virology, 84(9):4321-4329 (2010), Vivekanandan P. et al., Journal of Viral hepatitis 15(2):103-107 (2008), Jain S., et al., Scientific Reports 5: 10478 (2015)). Methylation of CpG islands II and III has been correlated to low levels of serum HBV DNA and HBsAg titres in patients (Zhang Y., et al., PlosOne 9(10):e110442 (2014)). HBV genotype, HBeAg positivity, patient age, and liver fibrosis stage have been found to correlate to cccDNA CpG methylation status. In vitro methylation studies have further confirmed that CpG island II methylation can markedly reduce cccDNA transcription and subsequent viral core DNA replication (Zhang Y., et al., PlosOne 9(10):e110442 (2014)), establishing the importance of chromatin for cccDNA regulation and as a potential target for therapy of chronic HBV infections. Anti-virals and broad epigenetic-modifying agents, such as IFNα have been attributed to reducing active histone post translational modifications thereby transcriptionally down-regulating transcription of cccDNA (Tropberger P. et al., PNAS, 112(42):E5715-E5724 (2015), Belloni L, et al., Journal of Clinical investigation 122L529-537 (2012), Allweiss L., et al., Journal of Hepatology 60:500-507 (2014), Lucifora J., et al., Science 343: 1221-1228 (2014)).

The provided embodiments are based on a recognition that epigenetically silencing one or more HBV viral genes, including those present on the cccDNA, might be a viable therapeutic approach to curing HBV infections. Disclosed herein are approaches to achieve amelioration of infection, and in some cases potentially a functional cure, from HBV via precise epigenetic silencing of the cccDNA form, relaxed circular DNA (rcDNA) form and of the HBV integrated into the human genomic DNA. The approaches described herein demonstrate high efficacy, safety, and stability. In some embodiments, the approaches target all the forms of HBV in the same approach, utilize non-mutagenic platforms, and targeting the source of transcription rather than downstream transcripts. As methylation can be inherited by the cellular progeny, the durability of the epi-editing approaches offers promise for treatment of HBV infection. In some embodiments, the approaches described herein target multiple locations on the virus genome to ensure deep and durable response across HBV variants. In some embodiments, the epigenetic approaches result in silencing of HBV replication, HBV transcription, and production of proteins form the HBV DNA. The provided embodiments are not contingent on immune reboot nor on infected hepatocyte clearance but are based on a direct epigenetic silencing (e.g., HBV repression).

In some embodiments, the DNA-binding domain is a nuclease-inactive Clustered Regularly Interspaced Short Palindromic Repeats associated (Cas) protein or variant thereof complexed with a guide RNA (gRNA). In such systems, the gRNA has a spacer sequence that is capable of hybridizing to the target site of the gene or regulatory element thereof. Also provided herein are related gRNAs, including Cas/gRNA combinations, polynucleotides, compositions, and methods involving or related to the epigenetic-modifying DNA targeting systems.

In some embodiments of the provided epigenetic-modifying DNA-targeting system, the DNA-binding domain is a protein domain that is engineered for sequence-specific binding to the target site.

In some embodiments, the DNA-targeting systems are multiplexed DNA-targeting systems that include a plurality of DNA-targeting modules, in which each DNA-targeting module targets a different target site of one or more genes or regulatory elements thereof. In some embodiments, the different targets sites are in the same region of the gene or regulatory element thereof.

In some embodiments, any two DNA-targeting modules of a DNA-targeting system may comprise shared (i.e. overlapping) components. In some embodiments, each DNA-targeting modules of a DNA-targeting system comprise shared (i.e. overlapping) components. For example, a DNA-targeting system may comprise a first DNA-targeting module comprising (a) a fusion protein comprising a Cas protein and a transcriptional repressor domain, and (b) a first gRNA that complexes with the Cas protein and targets a first target site of a first HBV gene or regulatory element thereof, and a second DNA-targeting module comprising (a) the fusion protein of the first DNA-targeting module, and (b) a second gRNA that complexes with the Cas protein and targets a second target site of a second HBV gene or regulatory element thereof.

Conversely, different Cas protein variants (e.g., SpCas9 and SaCas9) are compatible with different gRNA scaffold sequences and PAMs, as described herein. Thus, it is possible to engineer a single DNA-targeting system comprising multiple non-overlapping CRISPR/Cas-based DNA-targeting modules.

A. Target Sites and Target Positions

In any of the embodiments herein, the target site is a gene and/or regulatory element thereof in the Hepatitis B viral (HBV) genome. In some embodiments, the target site is present in a covalently closed circular DNA (cccDNA), relaxed circular DNA (rcDNA) and/or is integrated in the human genomic DNA. In some embodiments, the target site in a Hepatitis B viral DNA sequence. In some embodiments, the Hepatitis B viral DNA sequence is an HBV gene or a regulatory element thereof. In some embodiments, the target site is at or near a gene involved in HBV replication and/or HBV transcription. In some embodiments, the epigenetic-modifying DNA-targeting system comprises at least one DNA-targeting module for repressing transcription of one or more HBV by targeting to the target site. In some aspects, repressing transcription of the HBV gene, such as reduced gene expression, results in silencing of HBV replication (e.g., reduced HBV replication) and/or HBV transcription.

With reference to the provided disclosure, it is understood that a cell that is positive (+) for HBV (e.g., HBV infected cell) means that the cell expresses any of the HBV markers (e.g., HBV RNA transcripts and/or proteins) described herein. Likewise, it is understood that a cell that is negative (−) for a particular marker is a cell that does not express the marker at a level that is not detectable. Antibodies and other binding entities can be used to detect expression levels of marker proteins to identify or detect a given cell surface marker. Suitable antibodies may include polyclonal, monoclonal, fragments (such as Fab fragments), single chain antibodies and other forms of specific binding molecules. Antibody reagents for cell surface markers above are readily known to a skilled artisan. A number of well-known methods for assessing expression level of surface markers or proteins may be used, such as detection by affinity-based methods, e.g., immunoaffinity-based methods, e.g., in the context of surface markers, such as by flow cytometry. In some embodiments, the label is a fluorophore and the method for detection or identification of cell surface markers on cells (e.g. hepatocytes) is by flow cytometry. In some embodiments, different labels are used for each of the different markers by multicolor flow cytometry. In some embodiments, surface expression can be determined by flow cytometry, for example, by staining with an antibody that specifically binds to the marker and detecting the binding of the antibody to the marker.

In some embodiments, a cell (e.g. hepatocyte) is positive (pos or +) for a particular marker if there is detectable presence on or in the cell of a particular marker, which can be an intracellular marker or a surface marker (e.g., HBeAg, HBsAg). In some embodiments, surface expression is positive if staining by flow cytometry is detectable at a level substantially above the staining detected carrying out the same procedures with an isotype-matched control under otherwise identical conditions and/or at a level substantially similar to, or in some cases higher than, a cell known to be positive for the marker and/or at a level higher than that for a cell known to be negative for the marker. In some embodiments, a cell (e.g. a hepatocyte) contacted by a DNA-targeting system described herein, has decreased expression for a particular marker (e.g. HBeAg) if the staining is substantially lower than a similar cell that was not contacted by the DNA-targeting system.

In some embodiments, a cell (e.g. hepatocyte) is negative (neg or −) for a particular marker if there is an absence of detectable presence on or in the cell of a particular marker, which can be an intracellular marker or a surface marker. In some embodiments, surface expression is negative if staining is not detectable by flow cytometry at a level substantially above the staining detected carrying out the same procedures with an isotype-matched control under otherwise identical conditions and/or at a level substantially lower than a cell known to be positive for the marker and/or at a level substantially similar to a cell known to be negative for the marker.

In some embodiments, the phenotype of infected cells and/or individuals is characterized functionally. In some aspects, the phenotype can be characterized by the presence of HBV RNA transcripts in infected cells. In some aspects, the phenotype can be characterized by the presence of any one or combination of the HBV proteins in infected cells. In some aspects, the phenotype can be characterized by the presence of antibodies to any of the markers described herein. In some aspects, the antibodies include but are not limited to anti-HBc-IgM, anti-HBc total, and antibodies to HBeAg. In some embodiments, the RNA transcripts, proteins and/or antibodies are measured, detected, and/or quantified by any suitable technique known in the art. For instance, the RNA transcripts may be measured, detected and/or quantified using real-time PCR techniques. The HBV proteins (e.g., HBsAg, HBeAg and/or HBcrAg) may be measured, detected and/or quantified using enzyme-linked immunosorbent assays (ELISAs).

The target genes and/or regulatory elements thereof for modulation by the provided DNA-targeting systems, including multiplexed epigenetic-modifying DNA-targeting systems herein, include any whose transcription and expression are reduced in cells (e.g., HBV infected cells). Various methods may be utilized to characterize the transcription or expression levels of a gene in a cell (e.g. hepatocyte) such as after the cell has been contacted or introduced with a provided DNA-targeting system. In some embodiments, analyzing the transcription activity or expression of a gene may be by RNA analysis. In some embodiments, the RNA analysis includes RNA quantification. In some embodiments, the RNA quantification occurs by reverse transcription quantitative PCR (RT-qPCR), multiplexed qRT-PCR, fluorescence in situ hybridization (FISH), RNA-sequencing (RNA-seq) or combinations thereof.

In some embodiments, the gene or transcript is one in which expression of the gene or presence of the transcript in the cell (e.g. HBV infected cell, such as a hepatocyte), is reduced after having been contacted or introduced with a provided DNA-targeting system, such as a multiplexed epigenetic DNA-targeting system. In some aspects, a plurality of genes or transcripts are targeted by a multiplexed epigenetic DNA-targeting system, such as by one or more DNA-targeting modules thereof. In such system, each gene or transcript of a multiplexed DNA-targeting system is one in which expression of the gene or presence of the transcript in the cell is reduced after having been contacted or introduced with a provided multiplexed epigenetic DNA targeting system. In some embodiments, the reduction in gene expression or the change in the level of transcripts in a cell (e.g. HBV infected cell, such as a hepatocyte) is about a log 2 fold change of at least 1.25-fold, 1.5-fold, 1.75-fold, 2.0-fold, 2.5-fold, 2.75-fold, 3.0-fold, 3.25-fold, 3.5-fold, 3.75-fold, 4.0 fold, 4.25-fold, 4.5-fold, 4.75-fold, 5.0-fold, 5.25-fold, 5.5-fold, 5.75-fold, 6.25-fold, 6.50-fold, 6.75-fold, 7.0-fold. 7.25-fold, 7.50-fold, 7.75-fold, 8.0-fold, 8.25-fold, 8.5-fold, 8.75-fold, 9.0-fold or any value between any of the foregoing compared to the level of the gene in a control cell. In some embodiments, the reduction in gene expression or the change in the level of transcripts in a cell (e.g. HBV infected cell, such as a hepatocyte) is about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 90%, about 100% or any value between any of the foregoing compared to the level of gene in a control cell. In some embodiments, the reduction in gene expression or the change in the level of transcripts in a cell is greater than 90% compared to the level of gene in a control cell. In some embodiments, the guide RNAs are set forth in SEQ ID NOs:565, 528, 542, 508, 515, 575, 515, 453, 506, 514, 425, or 472. In some embodiments, the reduction in gene expression or the change in the level of transcripts in a cell is greater than 75% compared to the level of gene in a control cell.

In provided embodiments, the cccDNA transcribes five HBV RNAs (0.7 kb, 2.1 kb, 2.4 kb, longer and shorter 3.5 kb RNAs) under the host RNA polymerase. Transcription of cccDNA is controlled by four promoters—the basal core, preS1, preS2, and X promoters and two enhancers—enhancers I and II (FIG. 1). The 0.7-kb RNA can be translated to HBV X protein (HBx) which acts as a transcriptional regulator. The 2.1-kb RNA can be translated to HBV small surface protein (S) and middle surface protein (M). The 2.4-kb RNA can be translated to HBV large surface protein (L). L, M, and S can self-assemble to form empty subviral particles (SVPs) (including spherical SVPs and filamentous SVPs) that are secreted with only filamentous SVPs and virions containing significant amounts of L protein. The spherical SVPs are secreted through the constitutive secretory pathway. The filamentous SVPs are secreted by the endosomal sorting complex required for transport (ESCRT) machinery through multivesicular bodies (MVB). The longer 3.5-kb RNA is termed pre-core RNA (preC RNA) and can be translated to pre-Core protein, better known as HBV e antigen (HBeAg). The shorter 3.5-kb RNA is pre-genomic RNA (pgRNA) that has two roles, as the translation template for HBV polymerase (Pol) and Core proteins and as the replication template for intra-capsid (formed by Core protein polymerization) reverse transcription by Pol to form HBV rcDNA. These nucleocapsids can then be enveloped by HBV surface proteins (L, M, and S) to form mature virions and secreted through the ESCRT/MVB pathway. Alternatively, these nucleocapsids can also be transported to the nucleus to form cccDNA. In some embodiments, repressing transcription and/or translation of the HBV gene, such as reduced gene expression, results in silencing of any of the following HBV markers: HBV HBV X protein (HBx), Hepatitis B surface antigens (HBsAg) such as small surface protein (S), middle surface protein (M), or HBV large surface protein (L), HBV e antigen (HBeAg). In some embodiments, repressing transcription and/or translation of the HBV gene, such as reduced gene expression, results in silencing of HB core-related antigens (HBcrAg). HBcrAg includes 3 precore/core protein products, including hepatitis B core antigen (HBcAg), HBeAg, and a 22-kDA precore protein (p22cr). In some aspects, cccDNA, HBV total DNA, serum HBcrAg, HBsAg, HBeAg, hepatitis B core antibody (anti-HBc), HBV DNA, HBV RNA are quantified as readouts for measuring reduced HBV transcription and/or translation. In some embodiments, the target site is in a gene that encodes any of the HBV proteins. In some embodiments, the target site is in a regulatory element (e.g. promoter or enhancer) of a gene that encodes any of the HBV proteins.

In some embodiments, the target site is in a polymerase gene or a regulatory element thereof. The polymerase gene (also known as P gene) encodes a multifunctional enzyme (also known as P polymerase, HBVgpl, DNA-directed DNA polymerase) that converts the viral RNA genome into dsDNA in viral cytoplasmic capsids. The polymerase displays a DNA polymerase activity that can copy either DNA or RNA templates, and a ribonuclease H (RNase H) activity that cleaves the RNA strand of RNA-DNA heteroduplexes in a partially processive 3′- to 5′-endonucleasic mode. The polymerase gene ORF completely overlaps with the preS/S ORF and partially overlaps with the core family and X gene ORFs. In some embodiments, the target site is a sequence within a target region that has a sequence corresponding to the sequence positioned between 1 bp-1621 bp, 1374 bp-1838 bp or 2307 bp-3182 bp of the HBV genome with reference to the Hepatitis B Virus genome (Hepatitis B virus subtype ayw, complete genome, GenBank: U95551.1), SEQ ID NO: 650.

In some embodiments, the target site is in an S-family gene or a regulatory element thereof. In some embodiments, the target site is in the S gene, pre-S1 promoter, and/or pre-S2 promoter regions. The S-family genes encode three different structurally related envelope proteins, which are synthesized from alternative initiation codons are are termed Large (L), Middle (M), and Small (S) Hepatitis B (HB) proteins (also refered to as L-HBs, M-HBs, and s-HBs, respectively). The three proteins share the same carboxy-terminus but have different amino-terminal extenstions.

In some embodiments, the target site is in an X-gene or regulatory element thereof. The X-gene (also known as HBx, HBVgp3, peptide X, pX) is a gene that encodes a multifunctional protein that modulates transcriptional regulation, protein degradation pathways, apoptosis, signal transduction, cell cycle progress, and genetic stability by directly or indirectly interacting with host factors. The X-gene protein modulates protein degradation pathways, apoptosis, transcription, signal transduction, cell cycle progress, and genetic stability by directly or indirectly interacting with host factors. In some embodiments, the target site is a sequence within a target region that has a sequence corresponding to the sequence positioned between 1374 bp-1838 bp of the HBV genome with reference to the Hepatitis B Virus genome (Hepatitis B virus subtype ayw, complete genome, GenBank: U95551.1), SEQ ID NO: 650. In some embodiments, the start codon for encoding the HBx protein (HBx start codon) is at residue base pair 1376 of the HBV genome corresponding to positions with reference to the HBV genome set forth in SEQ ID NO: 650. In some embodiments, the start codon for encoding the HBx protein (HBx start codon) is at residue base pair 1374 of the HBV genome corresponding to positions with reference to the HBV genome set forth in SEQ ID NO: 1071. It is found herein that targeting a target site in the X-gene in this region upstream of the start codon using a provided epigenetic-modifying DNA targeting system exhibits high activity for repressing viral replication and transcription of HBV infected cells. In some embodiments, the target region is in a CpG island of the HBV genome. In some embodiments, the target site is a sequence within a target region that has a sequence corresponding to the sequence positioned between 1033-1749 bp with reference to the HBV genome set forth in SEQ ID NO:650. In some embodiments, the target site is in the HBx promoter/Enhancer #1 region, such as within a target region that has a sequence corresponding to the sequence positioned between 1100-1350 bp with reference to the HBV genome set forth in SEQ ID NO: 650. In some embodiments, the target site is in the basal core promoter region, such as within a target region that has a sequence corresponding to the sequence positioned between 1600-1750 bp with reference to the HBV genome set forth in SEQ ID NO: 650.

In some embodiments, the target site, or each of the target sites, is within a target region located at base pairs between 1060-1480 bp of the HBV genome corresponding to positions with reference to the HBV genome set forth in SEQ ID NO: 650. In some embodiments, the target site is within a target region of the HBV genome in which the target region has the sequence set forth in SEQ ID NO: 1067. Exemplary DNA-binding systems for targeting targets sites in such regions are provided herein, including systems with various DNA-binding domains including CRISPR/Cas systems and ZFPs.

In some embodiments, the target site is in a core family gene or regulatory element thereof. In some embodiments, the regulatory element thereof is an Enh2 promoter. In some embodiments, the regulatory element thereof is basal core promoter (BCP). The core promoter (CP) region of the viral genome has a pivot role in replication and morphogeneis of the virus (Quarleri J, World Journal of Gastroenterology 20(2): 425-435 (2014)). The core promoter region directs initiation of transcriptions for the synthesis of both the precore mRNA and pre-genomic RNA (pgRNA). The CP region consists of the basal core promoter (BCP), which initiates pre-core mRNA (also known as preC, C gene, HBVgp4) and pgRNA transcription, and consists of an upper regulatory region (URR), which contains positive and negative regulatory elements that modulate promoter activity. Several transcriptional factors bind to regulatory sequence elements of the CP, such as C/EBP, HNF1, HNF3/4, COUP-TF1 to differentially regulate synthesis of pre-C mRNA and pgRNA. The presence of AT-rich regions or TATA-like boxes within the CP are also attributed to transcription of pgRNA. The pre-core mRNA encodes an external core antigen (also known as capsid protein, pre-capsid protein, HBeAg, precore protein, p25) that self-assembles to form an icosahedral capsid that packages the viral genome. The pgRNA is translated to form the polymerase, nucleocapsid protein HBcAg, and the soluble secreted HBeAg proteins. The pgRNA is additionally incorporated into progeny nucleocapsids and reverse transcribed into DNA by the co-assembled viral polymerase into new HBV virions. These mature relaxed circular DNA (rcDNA)-containing nucleocapsids can either redeliver their genomes to the nucleus of the same cell to build a pool of 10-100 copied of cccDNA molecules or can interact with the envelope proteins at the ER/Golgi and can be secreted as new infectious virions (Pollicino T., et al., Journal of hepatology, 61(2):P408-417 (2014)). In some embodiments, the target site is in a core family gene or regulatory element thereof. In some aspects, targeting one or more sites within the core family gene or regulatory element thereof comprises repression of the pgRNA transcript. In some aspects, repression of the pgRNA transcript comprises silencing of HBV replication. In some embodiments, the target site is a sequence within a target region that has a sequence corresponding to the sequence positioned between 1590 bp-1815 bp, 1636 bp-1744, 1751 bp-1769, 1814 bp-1900 bp, 1816 bp-2455, 1800 bp-1950 bp of the HBV genome with reference to the Hepatitis B Virus genome (Hepatitis B virus subtype ayw, complete genome, GenBank: U95551.1), SEQ ID NO: 650. In some embodiments, reduced transcription comprises a reduction in total Hepatitis B viral RNA transcript levels. In some embodiments, reduced transcription comprises a reduction in Hepatitis B pre-core (“preC”) and/or pre-genomic (“pgRNA”) RNA levels.

In some aspects, the target site is a coding region. In some embodiments, the gene involved in HBV replication and/or HBV transcription encodes an HBV X protein (HBx), S family proteins (HBsAg) such as the small surface protein (S-HBs), middle surface protein (M-HBs), or HBV large surface protein (L-HBs), pre-core protein (HBeAg), HBV core-related antigen (HBcrAg), polymerase, core and precore proteins. In some aspects, the target site is a sequence within a target region that has a sequence corresponding to the sequence positioned between 1 bp-42 bp, 43 bp-1090 bp, 1091 bp-1849 bp, or 1850 bp-2455 bp or 2455 bp-3182 bp of the HBV genome with reference to the Hepatitis B Virus genome (Hepatitis B virus subtype ayw, complete genome, GenBank: U95551.1), SEQ ID NO: 650.

In some embodiments, repressing transcription comprises a reduction in Hepatitis B surface antigen (HBsAg) and/or Hepatitis B viral core-related-antigen (HBcrAg) protein levels. In some embodiments, repressing transcription comprises a reduction in HBsAg transcript and/or protein levels by at least 90%. In some embodiments, repressing transcription comprises a reduction in HBcrAg transcript and/or protein levels by at least 50% from the cccDNA.

In some embodiments, the multiplexed epigenetic-modifying DNA-targeting system targets to or binds to a target site in the gene, such as any described above. In some embodiments, the target site is located in a regulatory DNA element of the gene in the cell (e.g. hepatocyte). In some embodiments, a regulatory DNA element is a sequence to which a gene regulatory protein may bind and affect transcription of the gene. In some embodiments, the regulatory DNA element is a cis, trans, distal, proximal, upstream, or downstream regulatory DNA element of a gene. In some embodiments, the regulatory DNA element is a promoter or enhancer of the gene. In some embodiments, the target site is located within a promoter, enhancer, exon, intron, untranslated region (UTR), 5′ UTR, or 3′ UTR of the gene. In some embodiments, a promoter is a nucleotide sequence to which RNA polymerase binds to begin transcription of the gene. In some embodiments, a promoter is a nucleotide sequence typically located between 100 bp and 1000 bp of a transcription start site of a gene, such as within about 100 bp, about 500 bp, about 1000 bp of a transcriptional start site of the gene. In some embodiments the target site is located within a sequence of unknown or known function that is suspected of being able to control expression of a gene.

In some embodiments, the target site is located within about 50 base pairs (bp), about 100 bp, about 150 bp, about 200 bp, about 250 bp, about 300 bp, about 350 bp, about 400 bp, about 450 bp, about 500 bp, about 600b p, about 650 bp, about 700 bp, about 750 bp, about 800 bp, about 850 bp, about 900 bp, about 1000 bp, about 1050 bp, about 1100 bp, about 1200 bp, about 1250 bp, about 1300 bp, about 1350 bp about 1400 bp, about 1450 bp, about 1500 bp, of a transcription start site.

In some embodiments, the target site is positioned within a target region that is located at base pairs between 1 bp-3300 bp of the HBV genome. In some embodiments, the target site is a sequence within a target region that has a sequence corresponding to the sequence positioned between 43 bp-490 bp, 1033 bp-1749 bp, 1800 bp-1950 bp, or 2953 bp-3182 of the HBV genome with reference to the Hepatitis B Virus genome (Hepatitis B virus subtype ayw, complete genome, GenBank: U95551.1), SEQ ID NO 650. In some embodiments, the target site is a sequence within a target region that has a sequence corresponding to the sequence positioned between 1 bp-42 bp, 491 bp-1032 bp, 1750 bp-1799 bp, or 1951 bp-2952 bp or 3198 bp-3182 bp of the HBV genome with reference to the Hepatitis B Virus genome (Hepatitis B virus subtype ayw, complete genome, GenBank: U95551.1), SEQ ID NO 650. According to phylogenetic analyses and sequence divergence, HBV can be classified into 10 genotypes (A to J) based upon an inter-group divergence of 8 percent or more in the complete nucleotide sequence (Norder H, et. a., Complete genomes, phylogenetic relatedness, and structural proteins of six strains of the hepatitis B virus, four of which represent two new genotypes. Virology. 1994 February; 198(2):489-503; Stuyver L, et. al., A new genotype of hepatitis B virus: complete genome and phylogenetic relatedness. J Gen Virol. 2000 January; 81 (Pt 1):67-74, Arauz-Ruiz P, et. al., Genotype H: a new Amerindian genotype of hepatitis B virus revealed in Central America. J Gen Virol. 2002 August; 83 (Pt 8):2059-2073)). There is evidence suggesting that HBV genotypes influence clinical outcomes, mutational patterns in the precore and core promoter regions, HbeAg seroconversion rates, and response to interferon therapy. Most genotypes have specific geographic distributions; genotypes A and D are prevalent in Western Europe and North America, and genotypes B and C are prevalent in East Asia and Oceania.

B. CRISPR-Based DNA-Targeting Systems

Provided herein are epigenetic DNA-targeting systems based on CRISPR/Cas systems, i.e., CRISPR/Cas-based DNA-targeting systems that are able to bind to a target site in a target gene or regulatory element thereof. In some embodiments, the provided epigenetic DNA-targeting systems are multiplexed epigenetic-DNA-targeting systems based on CRISPR/Cas systems, i.e., CRISPR/Cas-based DNA-targeting systems that are able to target sites in a combination of target genes or regulatory element thereof.

In some embodiments, the CRISPR/Cas DNA-binding domain is nuclease inactive, such as includes a dCas (e.g. dCas9) so that the system binds to the target site in a target gene or regulatory element thereof without mediating nucleic acid cleavage at the target site. In some embodiments, the DNA-targeting system does not introduce a genetic disruption or a DNA break. The CRISPR/Cas-based DNA-targeting systems may be used to modulate expression of a target gene in a cell, such as a hepatocyte. In some embodiments, the target gene or regulatory element thereof may include any as described herein, including any described above in Section I.A. In some embodiments, the target site of the target gene or regulatory element thereof may include any as described herein, including any described above in Section I.A. In some embodiments, the CRISPR/Cas-based DNA-targeting system can include any known Cas enzyme, and generally a nuclease-inactive or dCas. In some embodiments, the CRISPR/Cas-based DNA-targeting system includes a fusion protein of a nuclease-inactive Cas protein or a variant thereof and an effector domain that reduces transcription of a gene (e.g., a transcriptional repressor), and at least one gRNA.

The CRISPR system (also known as CRISPR/Cas system, or CRISPR-Cas system) refers to a conserved microbial nuclease system, found in the genomes of bacteria and archaea, that provides a form of acquired immunity against invading phages and plasmids. Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR), refers to loci containing multiple repeating DNA elements that are separated by non-repeating DNA sequences called spacers. Spacers are short sequences of foreign DNA that are incorporated into the genome between CRISPR repeats, serving as a ‘memory’ of past exposures. Spacers encode the DNA-targeting portion of RNA molecules that confer specificity for nucleic acid cleavage by the CRISPR system. CRISPR loci contain or are adjacent to one or more CRISPR-associated (Cas) genes, which can act as RNA-guided nucleases for mediating the cleavage, as well as non-protein coding DNA elements that encode RNA molecules capable of programming the specificity of the CRISPR-mediated nucleic acid cleavage.

In Type II CRISPR/Cas systems with the Cas protein Cas9, two RNA molecules and the Cas9 protein form a ribonucleoprotein (RNP) complex to direct Cas9 nuclease activity. The CRISPR RNA (crRNA) contains a spacer sequence that is complementary to a target nucleic acid sequence (target site), and that encodes the sequence specificity of the complex. The trans-activating crRNA (tracrRNA) base-pairs to a portion of the crRNA and forms a structure that complexes with the Cas9 protein, forming a Cas/RNA RNP complex.

Naturally occurring CRISPR/Cas systems, such as those with Cas9, have been engineered to allow efficient programming of Cas/RNA RNPs to target desired sequences in cells of interest, both for gene-editing and modulation of gene expression. The tracrRNA and crRNA have been engineered to form a single chimeric guide RNA molecule, commonly referred to as a guide RNA (gRNA), for example as described in WO 2013/176772 A1, WO 2014/093661 A2, WO 2014/093655 A2, Jinek, M. et al. Science 337(6096):816-21 (2012), or Cong, L. et al. Science 339(6121):819-23 (2013). The spacer sequence of the gRNA can be chosen by a user to target the Cas/gRNA RNP complex to a desired locus, e.g. a desired target site in the target gene and/or regulatory element thereof.

Cas proteins have also been engineered to allow targeting of Cas/gRNA RNPs without inducing cleavage at the target site. Mutations in Cas proteins can reduce or abolish nuclease activity of the Cas protein, rendering the Cas protein catalytically inactive. Cas proteins with reduced or abolished nuclease activity are referred to as deactivated Cas (dCas), or nuclease-inactive Cas (iCas) proteins, as referred to interchangeably herein. Exemplary deactivated Cas9 (dCas9) derived from S. pyogenes contains silencing mutations of the RuvC and HNH nuclease domains (D10A and H840A), for example as described in WO 2013/176772 A1, WO 2014/093661 A2, Jinek, M. et al. Science 337(6096):816-21 (2012), and Qi, L. et al. Cell 152(5):1173-83 (2013). Exemplary dCas variants derived from the Cas12 system (i.e. Cpf1) are described, for example in WO 2017/189308 A1 and Zetsche, B. et al. Cell 163(3):759-71 (2015). Conserved domains that mediate nucleic acid cleavage, such as RuvC and HNH endonuclease domains, are readily identifiable in Cas orthologues, and can be mutated to produce inactive variants, for example as described in Zetsche, B. et al. Cell 163(3):759-71 (2015).

dCas-fusion proteins with transcriptional and/or epigenetic regulators have been used as a versatile platform for ectopically regulating gene expression in target cells. These include fusion of a Cas with an effector domain, such as a transcriptional activator or transcriptional repressor. For example, fusing dCas9 with a transcriptional activator such as VP64 (a polypeptide composed of four tandem copies of VP16, a 16 amino acid transactivation domain of the Herpes simplex virus) can result in robust induction of gene expression. Alternatively, fusing dCas9 with a transcriptional repressor such as KRAB (Kruppel associated box) can result in robust repression of gene expression. A variety of dCas-fusion proteins with transcriptional and epigenetic regulators can be engineered for regulation of gene expression, for example as described in WO 2014/197748, WO 2016/130600, WO 2017/180915, WO 2021/226555, WO 2013/176772, WO 2014/152432, WO 2014/093661, WO 2021/247570, Adli, M.

In such embodiments, the DNA-targeting system also includes one or more gRNAs, provided in combination or as a complex with the dCas protein or variant thereof, for targeting of the DNA-targeting system to the target site of the target gene or regulatory element thereof. In some embodiments, the fusion protein is guided to a specific target site sequence of the target geneor regulatory element thereof by the guide RNA, wherein the effector domain mediates targeted epigenetic modification to reduce or repress transcription of the target gene. In some embodiments, a combination of gRNAs guides the fusion protein to a combination of target site sequences in a combination of genes or regulatory elements thereof, wherein the effector domain mediates targeted epigenetic modification to reduce or repress transcription of the combination of target genes. Any of a variety of effector domains that reduce or repress transcription can be used as described further below.

Methods 10, 973-976 (2013), or Mali, P. et al. Nat. Biotechnol. 31, 833-838 (2013).

In some embodiments, the Cas protein is mutated so that nuclease activity is reduced or eliminated. Such Cas proteins are referred to as deactivated Cas or dead Cas (dCas) or nuclease-inactive Cas (iCas) proteins, as referred to interchangeably herein.

2. Guide RNAs

In some embodiments, the Cas protein (e.g. dCas9) is provided in combination or as a complex with one or more guide RNA (gRNA). In some aspects, the gRNA is a nucleic acid that promotes the specific targeting or homing of the gRNA/Cas RNP complex to the target site of the target gene and/or regulatory element thereof, such as any described above. In some embodiments, a target site of a gRNA may be referred to as a protospacer.

Provided herein are gRNAs, such as gRNAs that target or bind to a target site or DNA regulatory element thereof, such as any described above in Section I.A. In some embodiments, the gRNA is capable of complexing with the Cas protein or variant thereof. In some embodiments, the gRNA comprises a gRNA spacer sequence (i.e. a spacer sequence or a guide sequence) that is capable of hybridizing to the target site, or that is complementary to the target site, such as any target site described in Section I.A or further below. In some embodiments, the gRNA comprises a scaffold sequence that complexes with or binds to the Cas protein.

In some embodiments, the gRNAs provided herein are chimeric gRNAs. In general, gRNAs can be unimolecular (i.e. consisting of a single RNA molecule), or modular (comprising more than one, and typically two, separate RNA molecules). Modular gRNAs can be engineered to be unimolecular, wherein sequences from the separate modular RNA molecules are comprised in a single gRNA molecule, sometimes referred to as a chimeric gRNA, synthetic gRNA, or single gRNA. In some embodiments, the chimeric gRNA is a fusion of two non-coding RNA sequences: a crRNA sequence and a tracrRNA sequence, for example as described in WO 2013/176772 A1, or Jinek, M. et al. Science 337(6096):816-21 (2012). In some embodiments, the chimeric gRNA mimics the naturally occurring crRNA:tracrRNA duplex involved in the Type II Effector system, wherein the naturally occurring crRNA:tracrRNA duplex acts as a guide for the Cas9 protein.

In some aspects, the spacer sequence of a gRNA is a polynucleotide sequence comprising at least a portion that has sufficient complementarity with the target site or DNA regulatory element thereof (e.g. any described in Section I.A) to hybridize with a target site in the target gene and/or regulatory element thereof and direct sequence-specific binding of a CRISPR complex to the sequence of the target site. Full complementarity is not necessarily required, provided there is sufficient complementarity to cause hybridization and promote formation of a CRISPR complex. In some embodiments, the gRNA comprises a spacer sequence that is complementary, e.g., at least 80%, 85%, 90%, 95%, 98%, 99%, or 100% (e.g., fully complementary), to the target site. The strand of the target nucleic acid comprising the target site sequence may be referred to as the “complementary strand” of the target nucleic acid.

In some embodiments, the gRNA spacer sequence is between about 14 nucleotides (nt) and about 26 nt, or between 16 nt and 22 nt in length. In some embodiments, the gRNA spacer sequence is 14 nt, 15 nt, 16 nt, 17 nt, 18 nt, 19 nt, 20 nt, 21 nt or 22 nt, 23 nt, 24 nt, 25 nt, or 26 nt in length. In some embodiments, the gRNA spacer sequence is 18 nt, 19 nt, 20 nt, 21 nt or 22 nt in length. In some embodiments, the gRNA spacer sequence is 19 nt in length.

A target site of a gRNA may be referred to as a protospacer. In some aspects, the spacer is designed to target a protospacer with a specific protospacer-adjacent motif (PAM), i.e. a sequence immediately adjacent to the protospacer that contributes to and/or is required for Cas binding specificity. Different CRISPR/Cas systems have different PAM requirements for targeting. For example, in some embodiments, S. pyogenes Cas9 uses the PAM 5′-NGG-3′(SEQ ID NO:629), where N is any nucleotide. S. aureus Cas9 uses the PAM 5′-NNGRRT-3′ (SEQ ID NO:630), where N is any nucleotide, and R is G or A. N. meningitidis Cas9 uses the PAM 5′-NNNNGATT-3′ (SEQ ID NO:631), where N is any nucleotide. C. jejuni Cas9 uses the PAM 5′-NNNNRYAC-3′ (SEQ ID NO:632), where N is any nucleotide, R is G or A, and Y is C or T. S. thermophilus uses the PAM 5′-NNAGAAW-3′(SEQ ID NO:633), where N is any nucleotide and W is A or T. F. Novicida Cas9 uses the PAM 5′-NGG-3′ (SEQ ID NO:634), where N is any nucleotide. T. denticola Cas9 uses the PAM 5′-NAAAAC-3′(SEQ ID NO:635), where N is any nucleotide. Cas12a (also known as Cpf1) from various species, uses the PAM 5′-TTTV-3′(SEQ ID NO:636). Cas proteins may use or be engineered to use different PAMs from those listed above. For example, mutated SpCas9 proteins may use the PAMs 5′-NGG-3′(SEQ ID NO:629), 5′-NGAN-3′(SEQ ID NO:637), 5′-NGNG-3′(SEQ ID NO:638), 5′-NGAG-3′(SEQ ID NO:639), or 5′-NGCG-3′ (SEQ ID NO:640). In some embodiments, the protospacer of a gRNA for complexing with S. pyogenes Cas9 or variant thereof is set forth in SEQ ID NO: 588. In some embodiments, the protospacer of a gRNA for complexing with S. aureus Cas9 or variant thereof is set forth in SEQ ID NO: 589.

A spacer sequence may be selected to reduce the degree of secondary structure within the spacer sequence. Secondary structure may be determined by any suitable polynucleotide folding algorithm.

In some embodiments, the gRNA (including the guide sequence) will comprise the base uracil (U), whereas DNA encoding the gRNA molecule will comprise the base thymine (T). While not wishing to be bound by theory, in some embodiments, it is believed that the complementarity of the guide sequence with the target sequence contributes to specificity of the interaction of the gRNA molecule/Cas molecule complex with a target nucleic acid. It is understood that in a guide sequence and target sequence pair, the uracil bases in the guide sequence will pair with the adenine bases in the target sequence.

In some embodiments, one, more than one, or all of the nucleotides of a gRNA can have a modification, e.g., to render the gRNA less susceptible to degradation and/or improve bio-compatibility. By way of non-limiting example, the backbone of the gRNA can be modified with a phosphorothioate, or other modification(s). In some cases, a nucleotide of the gRNA can comprise a 2′ modification, e.g., a 2-acetylation, e.g., a 2′ methylation, or other modification(s).

Methods for designing gRNAs and exemplary targeting domains can include those described in, e.g., International PCT Pub. Nos. WO 2014/197748 A2, WO 2016/130600 A2, WO 2017/180915 A2, WO 2021/226555 A2, WO 2013/176772 A1, WO 2014/152432 A2, WO 2014/093661 A2, WO 2014/093655 A2, WO 2015/089427 A1, WO 2016/049258 A2, WO 2016/123578 A1, WO 2021/076744 A1, WO 2014/191128 A1, WO 2015/161276 A2, WO 2017/193107 A2, and WO 2017/093969 A1.

In some embodiments, the gRNA provided herein targets a target site present in a covalently closed circular DNA (cccDNA), relaxed circular DNA (rcDNA). In some aspects, the target site may be any HBV genome sequence optimal for depositing DNA methylation that results in silencing of HBV RNA transcription.

In some embodiments, the target site is at or near a gene or a regulatory element thereof involved in controlling HBV replication and/or HBV transcription. In some aspects, the target site is at or near a promoter. In some aspects, the target site is near an enhancer region.

C. Engineered Zinc Finger Proteins (eZFPs)

In some aspects, provided herein are zinc finger proteins (ZFPs), such as engineered zinc finger proteins (eZFPs). In some embodiments, the eZFPs are capable of binding to, or bind to, a target site in an HBV gene or a regulatory element of a gene in the Hepatitis B Virus sequence. In some aspects, the eZFP can facilitate specific targeting of effector domains for transcriptional repression of a gene or a regulatory element. In some embodiments, provided herein are epigenetic-modifying DNA-targeting systems comprising fusion proteins comprising the eZFP and one or more other elements, such as the effector domains for transcriptional repression. Thus, in some aspects the eZFP facilitates decreased expression of an HBV gene or regulatory element, for example in connection with compositions and methods for treating a disease or disorder associated with HBV such as an HBV viral infection, liver disease, or cancer.

In some embodiments, a zinc finger protein (ZFP), a zinc finger DNA binding protein, or zinc finger DNA binding domain, is a protein, or a domain within a larger protein, that binds DNA in a sequence-specific manner through one or more zinc fingers, which are regions of amino acid sequence within the binding domain, having a structure that is stabilized through coordination of a zinc ion. Among the ZFPs are artificial, or engineered, ZFPs (eZFPs), comprising ZFP domains targeting specific DNA sequences, typically 9-18 nucleotides long, generated by assembly of individual zinc fingers. ZFPs include those in which a single finger domain is approximately 30 amino acids in length and contains an alpha helix containing two invariant histidine residues coordinated through zinc with two cysteines of a single beta turn, and having two, three, four, five, or six fingers. Generally, sequence-specificity of a ZFP may be altered by making amino acid substitutions at the four helix positions (−1, 2, 3, and 6) on a zinc finger recognition helix, also called a zinc finger recognition region. Thus, for example, a ZFP or ZFP-containing molecule, such as a fusion protein, can be non-naturally occurring, e.g., is engineered to bind to a target site of choice.

In some embodiments, zinc fingers can be custom-designed (i.e. designed by the user), and/or obtained from a commercial source. Various methods for designing zinc finger proteins are available. For example, methods for designing zinc finger proteins to bind to a target DNA sequence of interest are described, for example in Liu, Q. et al., PNAS, 94(11):5525-30 (1997); Wright, D. A. et al., Nat. Protoc., 1(3):1637-52 (2006); Gersbach, C. A. et al., Acc. Chem. Res., 47(8):2309-18 (2014); Bhakta M. S. et al., Methods Mol. Biol., 649:3-30 (2010); and Gaj et al., Trends Biotechnol, 31(7):397-405 (2013). In addition, various web-based tools for designing zinc finger proteins to bind to a DNA target sequence of interest are publicly available. See, for example, the Zinc Finger Tools design web site from Scripps available on the world wide web at scripps.edu/barbas/zfdesign/zfdesignhome.php. Various commercial services for designing zinc finger proteins to bind to a DNA target sequence of interest are also available. See, for example, the commercially available services or kits offered by Creative Biolabs (world wide web at creative-biolabs.com/Design-and-Synthesis-of-Artificial-Zinc-Finger-Proteins.html), the Zinc Finger Consortium Modular Assembly Kit available from Addgene (world wide web at addgene.org/kits/zfc-modular-assembly/), or the CompoZr Custom ZFN Service from Sigma Aldrich (world wide web at sigmaaldrich.com/life-science/zinc-finger-nuclease-technology/custom-zfn.html).

In some embodiments, provided herein are epigenetic-modifying DNA-targeting systems comprising fusion proteins comprising the eZFP and one or more other elements, such as the effector domains for transcriptional repression. In some embodiments, the at least one DNA-binding domain of the epigeneticmodifying DNA-targeting system comprises an engineered zinc finger protein (eZFP). In some embodiments, the epigenetic-modifying DNA-targeting system comprises an engineered zinc finger protein (eZFP) that binds to a target site in one or more HBV genes or regulatory elements thereof. The target site targeted by any of the provided eZFP can be any as described herein, such as any target site described in Section I.A.

In some embodiments, the target site for an eZFP (e.g., such as an eZFP comprised in a fusion protein of an epigenetic-modifying DNA-targeting system) provided herein is in one or more HBV genes or regulatory elements thereof. In some embodiments, the target site is in a CpG island (e.g., CpG island 1, CpG island 2, CpG island 3) of the HBV genome. In some embodiments, the target site is in CpG island 2 of the HBV genome. In some embodiments, the target site is within a target region spanning 1033 bp-1749 bp of the HBV genome corresponding to positions with reference to the HBV genome set forth in SEQ ID NO: 650.

In some embodiments, the target region has the sequence set forth in SEQ ID NO: 1070.

In some embodiments, the target site for an eZFP (e.g., such as an eZFP comprised in a fusion protein of an epigenetic-modifying DNA-targeting system) provided herein comprises the nucleotide sequence set forth in any one of SEQ ID NOS:1028-1055 a contiguous portion thereof of at least 12 nt, or a complementary sequence of any of the foregoing.

D. Other DNA-Binding Domains

In some of any of the provided embodiments, the DNA-binding domain comprises a transcription activator-like effector (TALE); a meganuclease; a homing endonuclease; or an I-SceI enzyme or a variant thereof. In some embodiments, the DNA-binding domain comprises a catalytically inactive variant of any of the foregoing.

Transcription activator-like effectors (TALEs), are proteins naturally found in Xanthomonas bacteria. TALEs comprise a plurality of repeated amino acid sequences, each repeat having binding specificity for one base in a target sequence. Each repeat comprises a pair of variable residues in position 12 and 13 (repeat variable diresidue; RVD) that determine the nucleotide specificity of the repeat. In some embodiments, RVDs associated with recognition of the different nucleotides are HD for recognizing C, NG for recognizing T, NI for recognizing A, NN for recognizing G or A, NS for recognizing A, C, G or T, HG for recognizing T, IG for recognizing T, NK for recognizing G, HA for recognizing C, ND for recognizing C, HI for recognizing C, HN for recognizing G, NA for recognizing G, SN for recognizing G or A and YG for recognizing T, TL for recognizing A, VT for recognizing A or G and SW for recognizing A. In some embodiments, RVDs can be mutated towards other amino acid residues in order to modulate their specificity towards nucleotides A, T, C and G and in particular to enhance this specificity. Binding domains with similar modular base-per-base nucleic acid binding properties can also be derived from different bacterial species. These alternative modular proteins may exhibit more sequence variability than TALE repeats.

In some embodiments, a “TALE DNA binding domain” or “TALE” is a polypeptide comprising one or more TALE repeat domains/units. The repeat domains, each comprising a repeat variable diresidue (RVD), are involved in binding of the TALE to its cognate target DNA sequence. A single “repeat unit” (also referred to as a “repeat”) is typically 33-35 amino acids in length and exhibits at least some sequence homology with other TALE repeat sequences within a naturally occurring TALE protein. TALE proteins may be designed to bind to a target site using canonical or non-canonical RVDs within the repeat units. See, e.g., U.S. Pat. Nos. 8,586,526 and 9,458,205.

In some embodiments, a TALE is a fusion protein comprising a nucleic acid binding domain derived from a TALE and an effector domain. In some embodiments, one or more sites in the FXN locus can be targeted by engineered TALEs.

Zinc finger and TALE DNA-binding domains can be engineered to bind to a predetermined nucleotide sequence, for example via engineering (altering one or more amino acids) of the recognition helix region of a naturally occurring zinc finger protein, by engineering of the amino acids in a TALE repeat involved in DNA binding (the repeat variable diresidue or RVD region), or by systematic ordering of modular DNA-binding domains, such as TALE repeats or ZFP domains. Therefore, engineered zinc finger proteins or TALE proteins are proteins that are non-naturally occurring. Non-limiting examples of methods for engineering zinc finger proteins and TALEs are design and selection. A designed protein is a protein not occurring in nature whose design/composition results principally from rational criteria. Rational criteria for design include application of substitution rules and computerized algorithms for processing information in a database storing information of existing ZFP or TALE designs (canonical and non-canonical RVDs) and binding data. See, for example, U.S. Pat. Nos. 9,458,205; 8,586,526; 6,140,081; 6,453,242; and 6,534,261; see also WO 98/53058; WO 98/53059; WO 98/53060; WO 02/016536 and WO 03/016496.

E. Effector Domains

In some aspects, the DNA-targeting systems provided herein include one or more effector domains. In some embodiments, provided herein is a DNA-targeting system comprising a fusion protein comprising: (a) a DNA-binding domain for targeting to a target site in a Hepatitis B viral DNA sequence, such as a gene or regulatory element thereof, for example any described above, and (b) at least one effector domain. In some aspects, the effector domain is capable of reducing transcription of the gene, i.e. comprises a transcriptional repressor effector domain. In some aspects, the effector domain comprises a transcription repressor effector domain.

In some aspects, the effector domain, represses, induces, catalyzes, or leads to reduced transcription of a gene and/or regulatory element thereof when ectopically recruited to the gene or DNA regulatory element thereof.

In some embodiments, the effector domain induces, catalyzes or leads to transcription repression, transcription co-repression, transcription repression, transcription factor release, polymerization, histone modification, histone acetylation, histone deacetylation, nucleosome remodeling, chromatin remodeling, heterochromatin formation, proteolysis, ubiquitination, deubiquitination, phosphorylation, dephosphorylation, splicing, nucleic acid association, DNA methylation, DNA demethylation, histone methylation, histone demethylation, or DNA base oxidation. In some embodiments, the effector domain represses, induces, catalyzes or leads to transcription repression or transcription co-repression. In some embodiments, the effector domain induces transcription repression. In some embodiments, the effector domain has one of the aforementioned activities itself (i.e. acts directly). In some embodiments, the effector domain recruits and/or interacts with a polypeptide domain that has one of the aforementioned activities (i.e. acts indirectly).

Gene expression of endogenous mammalian genes, such as human genes, can be achieved by targeting a fusion protein comprising a DNA-binding domain, such as a dCas9, and an effector domain to mammalian genes or regulatory DNA elements thereof (e.g. a promoter or enhancer) via one or more gRNAs. Any of a variety of effector domains are known and can be used in accord with the provided embodiments. Repression of target genes and/or regulatory element thereof by such effector domains as Cas fusion proteins with a variety of Cas molecules and the transcriptional repressor domains, are described, for example, in WO2021226077, WO2017180915, WO2014197748, WO2014093655, US20190127713, WO2013176772, Adli, M. Nat. Commun. 9, 1911 (2018), Urrutia, R. Genome Biol. 4, 231 (2003), Groner, A. C. et al. PLoS Genet. 6, e1000869 (2010), Liu, X. S. et al. Cell 167, 233-247.e17 (2016), and Lei, Y. et al. Nat. Commun. 8, 16026 (2017).

In some embodiments, the effector domain may comprise a KRAB domain, ERF repressor domain, MXI1 domain, SID4X domain, MAD-SID domain, a DNMT family protein domain (e g DNMT3A or DNMT3B), a fusion of one or more DNMT family proteins or domains thereof (e.g. DNMT3A/L, which comprises a fusion of DNMT3A and DNMT3L domains), EZH2 domain, LSD1, a SunTag domain, a partially or fully functional fragment or domain of any of the foregoing, or a combination of any of the foregoing.

In some embodiments, the effector domain comprises a transcriptional repressor domain described in WO 2021/226077.

In some embodiments, the effector domain comprises a KRAB domain, or a variant thereof. The KRAB-containing zinc finger proteins make up the largest family of transcriptional repressors in mammals. The Krilppel associated box (KRAB) domain is a transcriptional repressor domain present in many zinc finger protein-based transcription factors. The KRAB domain comprises charged amino acids and can be divided into sub-domains A and B. The KRAB domain recruits corepressors KAP1 (KRAB-associated protein-1), epigenetic readers such as heterochromatin protein 1 (HP1), and other chromatin modulators to induce transcriptional repression through heterochromatin formation. KRAB-mediated gene repression is associated with loss of histone H3-acetylation and an increase in H3 lysine 9 trimethylation (H3K9me3) at the repressed gene promoters. KRAB domains, including in dCas fusion proteins, have been described, for example, in WO 2017/180915, WO 2014/197748, US 2019/0127713, WO 2013/176772, Urrutia R. et al.

In some embodiments, the effector domain comprises at least one ERF repressor domain, or a variant thereof. ERF (ETS2 repressor factor) is a strong transcriptional repressor that comprises a conserved ets-DNA-binding domain, and represses transcription via a distinct domain at the carboxyl-terminus of the protein. ERF repressor domains, including in dCas fusion proteins, have been described, for example, in WO2017180915, WO2014197748, WO2013176772, Mavrothalassitis, G., Ghysdael, J. Proteins of the ETS family with transcriptional repressor activity. Oncogene 19, 6524-6532 (2000).

In some embodiments, the effector domain comprises at least one MXI1 domain, or a variant thereof. The MXI1 domain functions by antagonizing the myc transcriptional activity by competing for binding to myc-associated factor x (MAX). MXI1 domains, including in dCas fusion proteins, have been described, for example, in WO2017180915, WO2014197748, US20190127713. In some embodiments, the effector domain comprises at least one MXI1 domain or a variant thereof. An exemplary MXI1 domain is set forth in SEQ ID NO: 601.

The MAD family proteins, Mad1, Mxi1, Mad3, and Mad4, belong to the basic helix-loop-helix-zipper class and contain a conserved N terminal region (termed Sin3 interaction domain (SID)) necessary for repressional activity. MAD-SID domains, including in dCas fusion proteins, have been described, for example, in WO2017180915, WO2014197748, WO2013176772.

In some embodiments, the effector domain is from a DNMT3 or is a portion or a functionally active variant thereof with DNA methyltransferase activity. The DNMT3A and DNMT3B are two DNA methyltransferases that catalyze de novo methylation, which depending on the site may be associated with transcriptional repression. DNMTs, such as DNMT3s, mediate transfer of a methyl group from the universal methyl donor, S-adenosyl-L-methionine (SAM), to the 5-position of cytosine residues. In some aspects, these DNMT3 DNA methyltransferases induce de novo methylation of a cytosine base to methylated 5-methylcytosine. DNMT3, including in dCas fusion proteins, have been described, for example, in US20190127713, Liu, X. S. et al. Cell 167, 233-247.e17 (2016), Lei, Y. et al. Nat. Commun. 8, 16026 (2017). DNMT3 proteins, such as DNMT3A and DNMT3B, contain an N-terminal part that is naturally involved in regulatory activity and targeting, and a C-terminal catalytic domain termed the MTase CS-type domain. In some embodiments, an effector domain in embodiments provided herein includes a catalytically active portion of a DNMT3A or a DNMT3B that contains a catalytically active C-terminal domain. In particular, isolated catalytic domains of DNMT3a and DNMT3b are catalytically active (see e.g. Gowher and Jeltsch (2002) J. Biol. Chem., 277:20409).

In some embodiments, the DNMT3 domain may be an effector domain of DNMT3A or DNMT3B that is catalytically active. In some embodiments, the effector domain may be the full-length of DNMT3A or DNMT3B or a catalytically active portion thereof. In some embodiments, the effector domain is a catalytically active portion that is less than the full-length sequence of DNMT3A or DNMT3B. In some embodiments, a catalytically active portion is a contiguous sequence of amino acids that confers DNA methyltransferase activity, such as by mediating methylation of a cytosine base to methylated 5-methylcytosine.

In some embodiments, the effector domain includes a DNMT3L, or a portion or a variant of DNMT3L or the portion thereof. DNMT3L (DNA (cytosine-5)-methyltransferase 3-like) is a catalytically inactive regulatory factor of DNA methyltransferases that can either promote or inhibit DNA methylation depending on the context. DNMT3L is essential for the function of DNMT3A and DNMT3B; DNMT3L interacts with DNMT3A and DNMT3B and enhances their catalytic activity. For instance, DNMT3L interacts with the catalytic domain of DNMT3A or DNMT3B to form a heterodimer, demonstrating that DNMT3L has dual functions of binding an unmethylated histone tail and activating DNA methyltransferase. In some embodiments, reference to a portion or variant of a DNMT3L for purposes herein refers to a sufficient C-terminal sequence portion of DNMT3L that interacts with the catalytic domain of DNMT3A or DNMT3B and is able to stimulate or promote DNA methyltransferase activity of DNMT3A or DNMT3B (see e.g. Jia et al. Nature, 2007, 449:248-251; Gowher et al. J. Biol. Chem., 2005, 280: 13341-13348). In some embodiments, the DNMT3L or portion thereof is of animal origin.

In some embodiments, a fusion protein of the DNA-targeting system, or a DNA-targeting module thereof, comprises one or more nuclear localization signals (NLS). In some embodiments, a fusion protein described herein comprises one or more nuclear localization sequences (NLSs), such as about or more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more NLSs. When more than one NLS is present, each may be selected independently of the others, such that a single NLS may be present in more than one copy and/or in combination with one or more other NLSs present in one or more copies. Non-limiting examples of NLSs include an NLS sequence derived from: the NLS of the SV40 virus large T-antigen, having the amino acid sequence PKKKRKV (SEQ ID NO: 614); the NLS from nucleoplasmin (e.g. the nucleoplasmin bipartite NLS with the sequence KRPAATKKAGQAKKKK (SEQ ID NO: 592); the c-myc NLS having the amino acid sequence PAAKRVKLD (SEQ ID NO: 615) or RQRRNELKRSP (SEQ ID NO: 616); the hRNPA1 M9 NLS having the sequence NQSSNFGPMKGGNFGGRSSGPYGGGGQYFAKPRNQGGY (SEQ ID NO: 617); the sequence RMRIZFKNKGKDTAELRRRRVEVSVELRKAKKDEQILKRRNV (SEQ ID NO: 618) of the IBB domain from importin-alpha; the sequences VSRKRPRP (SEQ ID NO: 619) and PPKKARED (SEQ ID NO: 620) of the myoma T protein; the sequence PQPKKKPL (SEQ ID NO: 621) of human p53; the sequence SALIKKKKKMAP (SEQ ID NO: 622) of mouse c-abl IV; the sequences DRLRR (SEQ ID NO: 623) and PKQKKRK (SEQ ID NO: 624) of the influenza virus NS1; the sequence RKLKKKIKKL (SEQ ID NO: 625) of the Hepatitis virus delta antigen; the sequence REKKKFLKRR (SEQ ID NO: 626) of the mouse Mxl protein; the sequence KRKGDEVDGVDEVAKKKSKK (SEQ ID NO: 627) of the human poly(ADP-ribose) polymerase; and the sequence RKCLQAGMNLEARKTKK (SEQ ID NO: 628) of the steroid hormone receptors (human) glucocorticoid. In general, the one or more NLSs are of sufficient strength to drive accumulation of the fusion protein in a detectable amount in the nucleus of a eukaryotic cell. In general, strength of nuclear localization activity may derive from the number of NLSs in the fusion protein, the particular NLS(s) used, or a combination of these factors. Detection of accumulation in the nucleus may be performed by any suitable technique. For example, a detectable marker may be fused to the fusion protein, such that location within a cell may be visualized, such as in combination with a means for detecting the location of the nucleus (e.g. a stain specific for the nucleus such as DAPI). Cell nuclei may also be isolated from cells, the contents of which may then be analyzed by any suitable process for detecting protein, such as immunohistochemistry, Western blot, or enzyme activity assay. Accumulation in the nucleus may also be determined indirectly, such as by an assay for the effect of the fusion protein (e.g. an assay for altered gene expression activity in a cell transformed with the DNA-targeting system comprising the fusion protein), as compared to a control condition (e.g. an untransformed cell). In some embodiments, the NLS comprises the sequence set forth in SEQ ID NO: 592 (KRPAATKKAGQAKKKK), or a portion thereof.

In some embodiments, the NLS is linked to the N-terminus or the C-terminus of the DNA-binding domain via a linker.

In some aspects, the moiety is or includes a Flag tag DYKDDDDK (SEQ ID NO:671), a 3×Flag tag MDYKDHDGDYKDHDIDUKDDDDK (SEQ ID NO: 674), an HA tag YPYDVPDYA (SEQ ID NO: 675) or a His such as HILT HHHHH (SEQ ID NO: 676).

1. Split Fusion Proteins

In some aspects, the split fusion protein comprises a dCas9 and an effector domain. In some aspects, the fusion protein comprises a split dCas9-effector domain fusion protein.

In some embodiments, the split fusion protein is assembled from separate polypeptide domains comprising trans-splicing inteins. Inteins are internal protein elements that self-excise from their host protein and catalyze ligation of flanking sequences with a peptide bond. In some embodiments, the split fusion protein is assembled from a first polypeptide comprising an N-terminal intein and a second polypeptide comprising a C-terminal intein. In some embodiments, the N terminal intein Is the N terminal Npu Intein set forth in SEQ ID NO:653. In some embodiments, the C terminal intein is the C terminal Npu intein set forth in SEQ ID NO:655. In some embodiments, the N terminal intein is the N terminal Npu Intein set forth in SEQ ID NO:652.

In some embodiments, the split fusion protein comprises a split dCas9-effector domain fusion protein assembled from two polypeptides. In an exemplary embodiment, the first polypeptide comprises an effector domain catalytic domain and an N-terminal fragment of dSpCas9, followed by an N terminal Npu Intein (effector domain-dSpCas9-573N), and the second polypeptide comprises a C terminal Npu Intein, followed by a C-terminal fragment of dSpCas9 (dSpCas9-573C; SEQ ID NO: 657). The N- and C-terminal fragments of the fusion protein are split at position 573 Glu of the dSpCas9 molecule, with reference to SEQ ID NO: 598 (corresponding to residue 572Glu of the dSpCas9 molecule set forth in SEQ ID NO: 599). In some aspects, the N-terminal Npu Intein (SEQ ID NO:653) and C-terminal Npu Intein (set forth in SEQ ID NO:655) may self-excise and ligate the two fragments, thereby forming the full-length dSpCas9-effector domain fusion protein when expressed in a cell.

In some embodiments, the polypeptides of a split protein may interact non-covalently to form a complex that recapitulates the activity of the non-split protein. For example, two domains of a Cas enzyme expressed as separate polypeptides may be recruited by a gRNA to form a ternary complex that recapitulates the activity of the full-length Cas enzyme in complex with the gRNA, for example as described in Wright et al. PNAS 112(10):2984-2989 (2015). In some embodiments, assembly of the split protein is inducible (e.g. light inducible, chemically inducible, small-molecule inducible).

In some aspects, the two polypeptides of a split fusion protein may be delivered and/or expressed from separate vectors, such as any of the vectors described herein. In some embodiments, the two polypeptides of a split fusion protein may be delivered to a cell and/or expressed from two separate AAV vectors, i.e. using a split AAV-based approach, for example as described in WO 2017/197238.

Approaches for the rationale design of split proteins and their delivery, including Cas proteins and fusions thereof, are described, for example, in WO 2016/114972, WO 2017/197238, Zetsche. et al. Nat. Biotechnol. 33(2):139-42 (2015), Wright et al. PNAS 112(10):2984-2989 (2015), Truong. et al. Nucleic Acids Res. 43, 6450-6458 (2015), and Fine et al. Sci. Rep. 5, 10777 (2015).

It is within the level of a skilled artisan to select the cationic lipids, non-cationic lipids and/or lipid conjugates which comprise the lipid nanoparticle, as well as the relative molar ratio of such lipids to each other, such as based upon the characteristics of the selected lipid(s), the nature of the delivery to the intended target cells, and the characteristics of the nucleic acids and/or proteins to be delivered. Additional considerations include, for example, the saturation of the alkyl chain, as well as the size, charge, pH, pKa, fusogenicity and toxicity of the selected lipid(s). Thus, the molar ratios of each individual component may be adjusted accordingly.

The lipid nanoparticles for use in the method can be prepared by various techniques which are known to a skilled artisan. Nucleic acid-lipid particles and methods of preparation are disclosed in, for example, U.S. Patent Publication Nos. 20040142025 and 20070042031.

In some embodiments, the lipid nanoparticles will have a size within the range of about 25 to about 500 nm. In some embodiments, the lipid nanoparticles have a size from about 50 nm to about 300 nm, or from about 60 nm to about 120 nm. The size of the lipid nanoparticles may be determined by quasi-electric light scattering (QELS) as described in Bloomfield, Ann. Rev. Biophys. Bioeng., 10:421A150 (1981). A variety of methods are known in the art for producing a population of lipid nanoparticles of particular size ranges, for example, sonication or homogenization. One such method is described in U.S. Pat. No. 4,737,323.

In some embodiments, the lipid nanoparticles comprise a cell targeting molecule such as, for example, a targeting ligand (e.g., antibodies, scFv proteins, DART molecules, peptides, aptamers, and the like) anchored on the surface of the lipid nanoparticle that selectively binds the lipid nanoparticles to the targeted cell, such as any cell described herein, e.g. a hepatocyte.

In some embodiments, the vector exhibits the vector exhibits liver cell and/or hepatocyte tropism.

In some aspects, provided herein are pluralities of vectors that comprise any of the vectors described herein, and one or more additional vectors comprising one or more additional polynucleotides encoding an additional portion or an additional component of any of the DNA-targeting systems described herein, any of the gRNAs described herein, any of the fusion proteins described herein, or a portion or a component of any of the foregoing.

Provided are pluralities of vectors, that include: a first vector comprising any of the polynucleotides described herein; a second vector comprising any of the polynucleotides described herein; and optionally one or more additional vectors comprising any of the polynucleotides described herein.

In some aspects, vectors provided herein may be referred to as delivery vehicles. In some aspects, any of the DNA-targeting systems, components thereof, or polynucleotides disclosed herein can be packaged into or on the surface of delivery vehicles for delivery to cells. Delivery vehicles contemplated include, but are not limited to, nanospheres, liposomes, quantum dots, nanoparticles, polyethylene glycol particles, hydrogels, and micelles. As described in the art, a variety of targeting moieties can be used to enhance the preferential interaction of such vehicles with desired cell types or locations.

Methods of introducing a nucleic acid into a host cell are known in the art, and any known method can be used to introduce a nucleic acid (e.g., an expression construct) into a cell. Suitable methods include, include e.g., viral or bacteriophage infection, transfection, conjugation, protoplast fusion, lipofection, electroporation, calcium phosphate precipitation, polyethyleneimine (PEI)-mediated transfection, DEAE-dextran mediated transfection, liposome-mediated transfection, particle gun technology, calcium phosphate precipitation, direct micro injection, nanoparticle-mediated nucleic acid delivery, and the like. In some embodiments, the composition may be delivered by mRNA delivery and ribonucleoprotein (RNP) complex delivery. Direct delivery of the RNP complex, including the DNA-binding domain complexed with the sgRNA, can eliminate the need for intracellular transcription and translation and can offer a robust platform for host cells with low transcriptional and translational activity. The RNP complexes can be introduced into the host cell by any of the methods known in the art.

Nucleic acids or RNPs of the disclosure can be incorporated into a host using virus-like particles (VLP). VLPs contain normal viral vector components, such as envelope and capsids, but lack the viral genome. For instance, nucleic acids expressing the Cas and sgRNA can be fused to the viral vector components such as gag and introduced into producer cells. The resulting virus-like particles containing the sgRNA-expressing vectors can infect the host cell for efficient editing.

Introduction of the complexes, polypeptides, and nucleic acids of the disclosure can occur by protein transduction domains (PTDs). PTDs, including the human immunodeficiency virus-1 TAT, herpes simplex virus-1 VP22, Drsophila Antennapedia Antp, and the poluarginines, are peptide sequences that can cross the cell membrane, enter a host cell, and deliver the complexes, polypeptides, and nucleic acids into the cell.

Introduction of the complexes, polypeptides, and nucleic acids of the disclosure into cells can occur by viral or bacteriophage infection, transfection, conjugation, protoplast fusion, lipofection, electroporation, nucleofection, calcium phosphate precipitation, polyethyleneimine (PEI)-mediated transfection, DEAE-dextran mediated transfection, liposome-mediated transfection, particle gun technology, calcium phosphate precipitation, direct micro-injection, nanoparticle-mediated nucleic acid delivery, and the like, for example as described in WO 2017/193107 A2, WO 2016/123578 A1, WO 2014/152432 A2, WO 2014/093661 A2, WO 2014/093655 A2, or WO 2021/226555 A2.

Various methods for the introduction of polynucleotides are well known and may be used with the provided methods and compositions. Exemplary methods include those for transfer of polynucleotides encoding the DNA targeting systems provided herein, including via viral, e.g., retroviral or lentiviral, transduction, transposons, and electroporation.

In some embodiments, polynucleotides can be cloned into a suitable vector, such as an expression vector or vectors. The expression vector can be any suitable recombinant expression vector, and can be used to transform or transfect any suitable cell. Suitable vectors include those designed for propagation and expansion or for expression or both, such as plasmids and viruses.

In some embodiments, the vector can a vector of the pUC series (Fermentas Life Sciences), the pBluescript series (Stratagene, LaJolla, Calif.), the pET series (Novagen, Madison, Wis.), the pGEX series (Pharmacia Biotech, Uppsala, Sweden), or the pEX series (Clontech, Palo Alto, Calif.). In some embodiments, animal expression vectors include pEUK-Cl, pMAM and pMAMneo (Clontech). In some embodiments, a viral vector is used, such as a lentiviral or retroviral vector. In some embodiments, the recombinant expression vectors can be prepared using standard recombinant DNA techniques. In some embodiments, vectors can contain regulatory sequences, such as transcription and translation initiation and termination codons, which are specific to the type of host into which the vector is to be introduced, as appropriate and taking into consideration whether the vector is DNA- or RNA-based. In some embodiments, the vector can contain a nonnative promoter operably linked to the nucleotide sequence encoding the recombinant receptor. In some embodiments, the promoter can be a non-viral promoter or a viral promoter, such as a cytomegalovirus (CMV) promoter, an SV40 promoter, an RSV promoter, and a promoter found in the long-terminal repeat of the murine stem cell virus. Other promoters known to a skilled artisan also are contemplated.

In some embodiments, recombinant nucleic acids are transferred into cells using recombinant infectious virus particles, such as, e.g., vectors derived from simian virus 40 (SV40), adenoviruses, or adeno-associated virus (AAV).

Most retroviral vectors are derived from murine retroviruses. In some embodiments, the retroviruses include those derived from any avian or mammalian cell source. The retroviruses typically are amphotropic, meaning that they are capable of infecting host cells of several species, including humans. In one embodiment, the gene to be expressed replaces the retroviral gag, pol and/or env sequences. A number of illustrative retroviral systems have been described (e.g., U.S. Pat. Nos. 5,219,740; 6,207,453; 5,219,740; Miller and Rosman (1989) BioTechniques 7:980-990; Miller, A. D. (1990) Human Gene Therapy 1:5-14; Scarpa et al. (1991) Virology 180:849-852; Burns et al. (1993) Proc. Natl. Acad. Sci. USA 90:8033-8037; and Boris-Lawrie and Temin (1993) Cur. Opin. Genet. Develop. 3: 102-109.

In some embodiments, the vector is a lentiviral vector. In some embodiments, the lentiviral vector is an integrase-deficient lentiviral vector. In some embodiments, the lentiviral vector is a recombinant lentiviral vector. In some embodiments, the lentivirus is selected or engineered for a desired tropism (e.g. for heptocyte cell tropism). Methods of lentiviral production, transduction, and engineering are known, for example as described in Kasaraneni, N. et al. Sci. Rep. 8(1):10990 (2018), Ghaleh, H. E. G. et al. Biomed. Pharmacother. 128:110276 (2020), and Milone, M. C. et al. Leukemia. 32(7):1529-1541 (2018). Additional methods for lentiviral transduction are described, for example in Wang et al. (2012) J. Immunother. 35(9): 689-701; Cooper et al. (2003) Blood. 101: 1637-1644; Verhoeyen et al. (2009) Methods Mol Biol. 506: 97-114; and Cavalieri et al. (2003) Blood. 102(2): 497-505.

In some embodiments, recombinant nucleic acids are transferred into cells (e.g. T cells) via electroporation (see, e.g., Chicaybam et al, (2013) PLoS ONE 8(3): e60298 and Van Tedeloo et al. (2000) Gene Therapy 7(16): 1431-1437). In some embodiments, recombinant nucleic acids are transferred into cells via transposition (see, e.g., Manuri et al. (2010) Hum Gene Ther 21(4): 427-437; Sharma et al. (2013) Molec Ther Nucl Acids 2, e74; and Huang et al. (2009) Methods Mol Biol 506: 115-126)). Other methods of introducing and expressing genetic material into cells include calcium phosphate transfection (e.g., as described in Current Protocols in Molecular Biology, John Wiley & Sons, New York. N.Y.), protoplast fusion, cationic liposome-mediated transfection; tungsten particle-facilitated microparticle bombardment (Johnston, Nature, 346: 776-777 (1990)); and strontium phosphate DNA co-precipitation (Brash et al., Mol. Cell Biol., 7: 2031-2034 (1987)).

III. PHARMACEUTICAL COMPOSITIONS AND FORMULATIONS

In some aspects, provided herein are compositions, such as pharmaceutical compositions and formulations for administration, that include any of the DNA-targeting systems described herein, or any of the polynucleotides or vectors encoding the same. In some aspects, the pharmaceutical composition contains one or more DNA-targeting systems provided herein or a component thereof. In some aspects, the pharmaceutical composition comprises one or more vectors, e.g., viral vectors that contain polynucleotides that encode one or more components of the DNA-targeting systems provided herein. Such compositions can be used in accord with the provided methods, and/or with the provided articles of manufacture or compositions, such as in the prevention or treatment of diseases, conditions, and disorders, or in detection, diagnostic, and prognostic methods.

The term “pharmaceutical formulation” refers to a preparation which is in such form as to permit the biological activity of an active ingredient contained therein to be effective, and which contains no additional components which are unacceptably toxic to a subject or a cell to which the formulation would be administered.

In some embodiments, the pharmaceutical composition may further comprise a pharmaceutically acceptable excipient. The pharmaceutically acceptable excipient may be functional molecules as vehicles, adjuvants, carriers, or diluents.

A “pharmaceutically acceptable carrier” refers to an ingredient in a pharmaceutical formulation, other than an active ingredient, which is nontoxic to a subject. A pharmaceutically acceptable carrier includes, but is not limited to, a buffer, excipient, stabilizer, or preservative.

In some aspects, the choice of carrier is determined in part by the particular agent and/or by the method of administration. Accordingly, there are a variety of suitable formulations. For example, the pharmaceutical composition can contain preservatives. Suitable preservatives may include, for example, methylparaben, propylparaben, sodium benzoate, and benzalkonium chloride. In some aspects, a mixture of two or more preservatives is used. The preservative or mixtures thereof are typically present in an amount of about 0.0001% to about 2% by weight of the total composition. Carriers are described, e.g., by Remington's Pharmaceutical Sciences 16th edition, Osol, A. Ed. (1980). Pharmaceutically acceptable carriers are generally nontoxic to recipients at the dosages and concentrations employed, and include, but are not limited to: buffers such as phosphate, citrate, and other organic acids; antioxidants including ascorbic acid and methionine; preservatives (such as octadecyldimethylbenzyl ammonium chloride; hexamethonium chloride; benzalkonium chloride; benzethonium chloride; phenol, butyl or benzyl alcohol; alkyl parabens such as methyl or propyl paraben; catechol; resorcinol; cyclohexanol; 3-pentanol; and m-cresol); low molecular weight (less than about 10 residues) polypeptides; proteins, such as serum albumin, gelatin, or immunoglobulins; hydrophilic polymers such as polyvinylpyrrolidone; amino acids such as glycine, glutamine, asparagine, histidine, arginine, or lysine; monosaccharides, disaccharides, and other carbohydrates including glucose, mannose, or dextrins; chelating agents such as EDTA; sugars such as sucrose, mannitol, trehalose or sorbitol; salt-forming counter-ions such as sodium; metal complexes (e.g. Zn-protein complexes); and/or non-ionic surfactants such as polyethylene glycol (PEG).

In some embodiments, the pharmaceutically acceptable excipient may be a transfection facilitating agent, which may include surface active agents, such as immune-stimulating complexes (ISCOMS), Freunds incomplete adjuvant, LPS analog including monophosphoryl lipid A, muramyl peptides, quinone analogs, vesicles such as squalene and squalene, hyaluronic acid, lipids, liposomes, calcium ions, viral proteins, polyanions, polycations, or nanoparticles, or other known transfection facilitating agents.

In some embodiments, the transfection facilitating agent is a polyanion, polycation, including poly-L-glutamate (LGS), or lipid. In some embodiments, the transfection facilitating agent is poly-L-glutamate. In some embodiments, the transfection facilitating agent may also include surface active agents such as immune-stimulating complexes (ISCOMS), Freunds incomplete adjuvant, LPS analog including monophosphoryl lipid A, muramyl peptides, quinone analogs and vesicles such as squalene and squalene, and hyaluronic acid may also be used administered in conjunction with the genetic construct. In some embodiments, the DNA vector encoding the DNA-targeting system may also include a transfection facilitating agent such as lipids, liposomes, including lecithin liposomes or other liposomes known in the art, as a DNA-liposome mixture (see for example WO9324640), calcium ions, viral proteins, polyanions, polycations, or nanoparticles, or other known transfection facilitating agents. In some embodiments, the transfection facilitating agent is a polyanion, polycation, including poly-L-glutamate (LGS), or lipid.

Compositions in some embodiments are provided as sterile liquid preparations, e.g., isotonic aqueous solutions, suspensions, emulsions, dispersions, or viscous compositions, which may in some aspects be buffered to a selected pH. Liquid preparations are normally easier to prepare than gels, other viscous compositions, and solid compositions. Additionally, liquid compositions are somewhat more convenient to administer, especially by injection. Viscous compositions, on the other hand, can be formulated within the appropriate viscosity range to provide longer contact periods with specific tissues. Liquid or viscous compositions can comprise carriers, which can be a solvent or dispersing medium containing, for example, water, saline, phosphate buffered saline, polyol (for example, glycerol, propylene glycol, liquid polyethylene glycol) and suitable mixtures thereof.

Sterile injectable solutions can be prepared by incorporating the agent in a solvent, such as in admixture with a suitable carrier, diluent, or excipient such as sterile water, physiological saline, glucose, dextrose, or the like. The formulations to be used for in vivo or ex vivo administration or use are generally sterile. Sterility may be readily accomplished, e.g., by filtration through sterile filtration membranes.

The pharmaceutical composition in some embodiments contains components in amounts effective to treat or prevent the disease or condition, such as a therapeutically effective or prophylactically effective amount. Therapeutic or prophylactic efficacy in some embodiments is monitored by periodic assessment of treated subjects. For repeated administrations over several days or longer, depending on the condition, the treatment is repeated until a desired suppression of disease symptoms occurs. However, other dosage regimens may be useful and can be determined. The desired dosage can be delivered by a single bolus administration of the composition, by multiple bolus administrations of the composition, or by continuous infusion administration of the composition.

In some embodiments, the composition can be administered to a subject by any suitable means, for example, by bolus infusion or by injection, e.g., by intravenous or subcutaneous injection. In some embodiments, a given dose is administered by a single bolus administration of the composition. In some embodiments, the composition is administered by multiple bolus administrations of the composition, for example, over a period of no more than 3 days, or by continuous infusion administration of the composition. In some embodiments, the composition is administered parenterally, for example by intravenous, intramuscular, subcutaneous, or intraperitoneal administration. In some embodiments, the composition is administered to a subject using peripheral systemic delivery by intravenous, intraperitoneal, or subcutaneous injection.

For the prevention or treatment of disease, the appropriate dosage may depend on the type of disease to be treated, the type of agent or agents, the type of cells or recombinant receptors, the severity and course of the disease, whether the agent or cells are administered for preventive or therapeutic purposes, previous therapy, the subject's clinical history and response to the agent or the cells, and the discretion of the attending physician. The compositions are in some embodiments suitably administered to the subject at one time or over a series of treatments.

Provided herein are methods of treatment, e.g., including administering any of the compositions, such as pharmaceutical compositions described herein. In some aspects, also provided are methods of administering any of the compositions described herein to a subject, such as a subject that has a disease or disorder. The compositions, such as pharmaceutical compositions, described herein are useful in a variety of therapeutic, diagnostic and prophylactic indications. For example, the compositions are useful in treating a variety of diseases and disorders in a subject (e.g., human). Such methods and uses include therapeutic methods and uses, for example, involving administration of the compositions, to a subject having a disease, condition, or disorder, such as an HBV viral infection or is associated with an HBV viral infection. In certain embodiments, the subject has been diagnosed with liver disease caused by a Hepatitis B virus infection or a Hepatitis B virus infection. In some embodiments, the HBV viral infection or the associated HBV viral infection is selected from hepatitis D virus infection, delta hepatitis, acute hepatitis B, acute fulminant hepatitis B, chronic hepatitis B, liver fibrosis, end-stage liver disease, or cancer such as hepatocellular carcinoma. The compositions are administered in an effective amount to effect treatment of the disease or disorder. Uses include uses of the compositions in such methods and treatments, and in the preparation of a medicament in order to carry out such therapeutic methods. In some embodiments, the methods are carried out by administering the compositions to the subject having or suspected of having the disease or condition. In some embodiments, the methods thereby treat the disease or condition or disorder in the subject. Also provided are therapeutic methods for administering the cells and compositions to subjects, e.g., patients.

In some embodiments, the compositions include a DNA-targeting system provided herein, or a polynucleotide or vector encoding the same, in which delivery of the composition to a subject represses transcription of one or more HBV genes and/or regulatory elements thereof resulting in silencing of HBV replication and/or HBV transcription in a subject to thereby treat a disease or condition, including chronic Hepatitis B infection. In some embodiments, administration or use of a composition that includes a DNA-targeting system provided herein, or a polynucleotide or vector encoding the same, reduces expression of one or more genes and/or regulatory elements thereof related to Hepatitis B viral replication and/or HBV transcription. In some embodiments, the Hepatitis B genes and/or regulatory elements thereof are present in a covalently closed circular (cccDNA) form, a relaxed circular DNA (rcNDA) form or are integrated into the human genomic DNA.

In some aspects, also provided herein are methods of reducing transcription of a Hepatitis B viral DNA sequence, to reduce chronic Hepatitis B infection in a subject, according to any description provided herein. In some aspects, reducing transcription of a Hepatitis B viral DNA sequence results in silencing of Hepatitis B viral replication and/or transcription. For instance, reduced transcription of the Hepatitis B viral DNA sequences results in a reduction of HBsAg transcripts and/or total HBV RNA. Reduced transcription of the Hepatitis B viral DNA sequences may also result in reduced HBsAg levels from integrated and cccDNA form and/or HBcrAg levels from cccDNA form.

In some embodiments, the methods of administering a composition containing the DNA-targeting system or a polynucleotide or vector encoding the same to a subject as provided herein are carried out in vivo (i.e. in a subject).

In some embodiments, the methods and uses for administering the DNA-targeting systems result in delivery of the DNA-targeting system to liver cells (e.g. hepatocytes). In some embodiments, the methods of administering the epigenetic-modifying DNA-targeting system (or polynucleotides or vectors for delivery of same to the liver cell(s) or compositions of any of the foregoing) to a subject contacts the DNA-targeting system with a liver cell or a population of liver cells. In some embodiments, the contacting introduces the epigenome-modifying DNA-targeting system (or polynucleotides or vectors for delivery of same to the liver cell or compositions of any of the foregoing) into the liver cell, such as where it is able to translocate or localize to the nucleus of the liver cell. In some embodiments, the methods treat an HBV infection in the liver cell or one or more liver cells in the population.

In some embodiments, the delivery to liver cells leads to an epigenetic change in the HBV gene or regulatory element, or a combination of genes or regulatory elements, which are targeted by the DNA-targeting system. In some embodiments, the epigenetic change comprises a change in at least one of: DNA accessibility, histone methylation, acetylation, phosphorylation, ubiquitylation, sumoylation, ribosylation, citrullination, and DNA methylation. In some embodiments, the epigenetic change is an altered DNA methylation of a target site in a target gene or a regulatory element thereof as described herein. In some embodiments, the epigenetic change is a histone modification of a target site in a target gene or a regulatory element thereof as described herein. In some embodiments, the delivery of the DNA-targeting system to a liver cell (e.g. hepatocyte) results in reduction of transcription of HBV genes and/or regulatory element thereof in the liver of the subject.

In some embodiments, the modifications in the HBV epigenome is by targeting a combination of genes and/or regulatory elements thereof as described herein with a provided epigenetic-modifying DNA-targeting system to change the epigenome of HBV. In some embodiments, the modified HBV includes an epigenetic change in a target site at or near a gene or regulatory element thereof involved in controlling HBC replication and/or HBV transcription, comprising polymerase gene, S-family gene, X-gene, or core family gene, or a promoter, enhancer, or a transscript processing control region. In some embodiments, the epigenetic change of any of the above target sites is a change in at least one of: DNA accessibility, histone methylation, acetylation, phosphorylation, ubiquitylation, sumoylation, ribosylation, citrullination, and DNA methylation, compared to a comparable unmodified cell (e.g. liver cell) not subjected to the method, i.e. not contacted or introduced with the DNA-targeting system described herein.

In some embodiments, the administration of the DNA-binding system modulates expression of a gene and/or regulatory element thereof or a combination of genes and/or regulatory element thereof in a liver cell, such as those described in Section I.A. In some embodiments, the gene, transcript or combination of genes and transcripts, such as those described in Section I.A, is reduced in comparison to a comparable unmodified cell (e.g. liver) not subjected to the method, i.e. not contacted or introduced with the DNA-targeting system described herein. In some embodiments, the transcription of the one or more genes is reduced by at least about 1.2-fold, 1.25-fold, 1.3-fold, 1.4-fold, 1.5-fold, 1.6-fold, 1.7-fold, 1.75-fold, 1.8-fold, 1.9-fold, 2-fold, 2.5-fold, 3-fold, 4-fold, 5-fold, 10-fold, 20-fold, 30-fold, 40-fold, 50-fold, 100-fold, 200-fold, 300-fold, 400-fold, 500-fold, 1000-fold or more. In some embodiments, generation of transcripts is reduced by at least about 1.2-fold, 1.25-fold, 1.3-fold, 1.4-fold, 1.5-fold, 1.6-fold, 1.7-fold, 1.75-fold, 1.8-fold, 1.9-fold, 2-fold, 2.5-fold, 3-fold, 4-fold, 5-fold, 10-fold, 20-fold, 30-fold, 40-fold, 50-fold, 100-fold, 200-fold, 300-fold, 400-fold, 500-fold, 1000-fold or more. In some embodiments, reduced transcription of the combination of genes and/or regulatory elements thereof reduces HBV replication and protein levels, in a subject. In some embodiments, the liver cell in the subject has been modulated to have reduced transcription of the polymerase gene, S-family gene, X-gene, or core-family gene. In some embodiments, the expression of each gene of the combination of genes in the modified liver cell is reduced by at least 1.2-fold or more compared to the expression of the same gene in a comparable unmodified liver cell, such as reduced by at or about or greater than 2-fold, 3-fold, 4-fold, 5-fold, 6-fold, 7-fold, 8-fold, 9-fold, 10-fold or more.

In some embodiments, the disease, condition, or disorder to be treated is in the liver. In some embodiments, the disease, condition, or disorder to be treated is liver disease, cancer, or viral infection. In some embodiments, the disease, condition, or disorder to be treated is hepatitis. In some embodiments, the condition to be treated is liver failure. In some embodiments, the liver failure is fulminant liver failure. In some embodiments, the disease or condition to be treated is liver cirrhosis. In some embodiments, the disease or condition to be treated is a cancer. In some embodiments, the cancer is a solid tumor cancer. In some embodiments, the cancer is hepatocellular cancer. In some embodiments, the hepatitis is acute hepatitis. In some embodiments, the hepatitis is chronic hepatitis.

In some embodiments, the subject has or is suspected of having elevated levels of HBV transcripts in the liver cells, elevated levels of HBV proteins inside and on the surface of liver cells, and elevated levels of circulating antibodies to HBV proteins. In some embodiments, the subject has or is suspected of having liver disease (e.g., hepatitis), cancer (e.g., hepatocellular carcinoma), or HBV infection (acute or chronic hepatitis).

Once the multiplexed epigenetic-modifying DNA-targeting system is administered to the subject (e.g., human), the biological activity of the modified cell populations in some aspects is measured by any of a number of known methods. Parameters to assess include reduced levels of HBV transcripts and/or HBV DNA levels in the liver cells (e.g. by qRT-PCR/qPCR), reduced levels of of HBV proteins (e.g., HBsAg, HBeAg) inside and on the surface of the liver cells (e.g., assessed by fluorescence staining and flow cytometry), and/or HBeAg, measured by analysis of blood serum using ELISA). In some aspects the biological activity is measured by assessing clinical outcome. Specific thresholds for the parameters can be set to determine the efficacy of the methods of therapy provided herein.

Also provided are methods of reducing transcription of one or more genes in a cell comprising a Hepatitis B viral sequence. In some embodiments, the method comprises introducing into the cell an epigenetic-modifying DNA-targeting system that induces targeted CpG methylation of a CpG island in a Hepatitis B viral sequence. In some embodiments, the method comprises introducing into the cell an epigenetic-modifying DNA-targeting system that induces targeted CpG methylation of CpG island 2 in a Hepatitis B viral sequence.

CpG islands are genomic regions that contain a high frequency of CG dinucleotides. Thus, these regions generally have a GC percentage that is greater than about 50% and with an observed/expected CpG ratio that is greater than about 60%. (Gardiner-Garden et al. “CpG islands in vertebrate genomes,” J Mol Biol 196: 261-282 (1987)). CpG islands are often located in the vicinity of genes. Methylation comprises epigenetic methylation of cytosine residues in DNA at sites where it is not typically present in normal cells. Detection of methylation of the CpG islands can be carried out according to methods of this invention, as well as any art-known method, including, but not limited to, e.g., methylation specific-polymerase chain reaction (MS-PCR), a method of nucleic acid amplification that is well known in the art. In this assay, bisulfite modification of the DNA sequence allows the detection of differences between methylated and unmethylated alleles. Reaction of the DNA with sodium bisulfite converts all unmethylated cytosines to uracil, which is recognized as thymine by Taq polymerase, but does not affect methylated cytosines. Amplification with primers specific for methylated or unmethylated DNA discriminates between methylated and unmethylated DNA. This assay provides a simple and fast way of surveying multiple samples to detect methylation of cytosines in the region of interest (Widschwendter et al., “Methylation and silencing of the retinoic acid receptor-beta2 gene in breast cancer” J Natl. Cancer Inst. 92(10):826-832 (2000)). Other methods known in the art for detection and/or quantitative analysis of DNA methylation include, but are not limited to, the chromatin immunoprecipitation assay (ChIP) (Mulero-Navarro et al., Carcinogenesis 27:1099-1104 (2006); Nakagawachi et al., Oncogene 22:8835-8844 (2003)); MethyLight®, a bisulfite modification-dependent fluorescence-based real time PCR assay (Eads et al. Nucleic Acids Res. 28(8) e32 (2000); Erhlich et al., Oncogene 21:6694-6702 (2002)); pyrosequencing (Lee et al. Clinical Cancer Research 14:2664-2672 (2008); Dejeux et al., J. Mol. Diagn. 9:510-520 (2007)); and the Sequenom® MassARRAY® system (Sequenom, Inc., San Diego, Calif.), which utilizes MALDI-TOF mass spectrometry in combination with RNA base specific cleavage (MassCLEAVE™ kit) (Sequenom, Inc., San Diego, Calif.).

VI. DEFINITIONS

Unless defined otherwise, all terms of art, notations and other technical and scientific terms or terminology used herein are intended to have the same meaning as is commonly understood by one of ordinary skill in the art to which the claimed subject matter pertains. In some cases, terms with commonly understood meanings are defined herein for clarity and/or for ready reference, and the inclusion of such definitions herein should not necessarily be construed to represent a substantial difference over what is generally understood in the art.

As used herein, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. For example, “a” or “an” means “at least one” or “one or more.” It is understood that aspects and variations described herein include “consisting” and/or “consisting essentially of” aspects and variations.

Throughout this disclosure, various aspects of the claimed subject matter are presented in a range format. It should be understood that the description in range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of the claimed subject matter. Accordingly, the description of a range should be considered to have specifically disclosed all the possible sub-ranges as well as individual numerical values within that range. For example, where a range of values is provided, it is understood that each intervening value, between the upper and lower limit of that range and any other stated or intervening value in that stated range is encompassed within the claimed subject matter. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges, and are also encompassed within the claimed subject matter, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the claimed subject matter. This applies regardless of the breadth of the range.

The term “about” as used herein refers to the usual error range for the respective value readily known. Reference to “about” a value or parameter herein includes (and describes) embodiments that are directed to that value or parameter per se. For example, description referring to “about X” includes description of “X”. In some embodiments, “about” may refer to ±25%, ±20%, ±15%, ±10%, ±5%, or ±1%.

As used herein, the term, “corresponding to” with reference to positions of a nucleotide sequence (or base pair) or protein sequence (amino acid), such as recitation that nucleotides or amino acid positions “correspond to” base pair or amino acid positions in a disclosed sequence, such as set forth in the Sequence listing, refers to nucleotides or amino acid positions identified upon alignment with the disclosed sequence to maximize identity using a standard alignment algorithm, such as the GAP algorithm. By aligning the sequences, corresponding residues can be identified, for example, using conserved and identical amino acid residues as guides. In general, to identify corresponding positions, the sequences of amino acids are aligned so that the highest order match is obtained (see, e.g.: Computational Molecular Biology, Lesk, A. M., ed., Oxford University Press, New York, 1988; Biocomputing: Informatics and Genome Projects, Smith, D. W., ed., Academic Press, New York, 1993; Computer Analysis of Sequence Data, Part I, Griffin, A. M., and Griffin, H. G., eds., Humana Press, New Jersey, 1994; Sequence Analysis in Molecular Biology, von Heinje, G., Academic Press, 1987; and Sequence Analysis Primer, Gribskov, M. and Devereux, J., eds., M Stockton Press, New York, 1991; Carrillo et al. (1988) SIAM J Applied Math 48: 1073).

A “gene,” includes a DNA region encoding a gene product, as well as all DNA regions which regulate the production of the gene product, whether or not such regulatory sequences are adjacent to coding and/or transcribed sequences. Accordingly, a gene includes, but is not necessarily limited to, promoter sequences, terminators, translational regulatory sequences such as ribosome binding sites and internal ribosome entry sites, enhancers, silencers, insulators, boundary elements, replication origins, matrix attachment sites and locus control regions. The sequence of a gene is typically present at a fixed chromosomal position or locus on a chromosome in the cell.

A “regulatory element” or “DNA regulatory element,” which terms are used interchangeably herein, in reference to a gene refers to DNA regions which regulate the production of a gene product, whether or not such regulatory sequences are adjacent to coding and/or transcribed sequences. Accordingly, a regulatory element includes, but is not necessarily limited to, promoter sequences, terminators, translational regulatory sequences such as ribosome binding sites and internal ribosome entry sites, enhancers, silencers, insulators, boundary elements, replication origins, matrix attachment sites and locus control regions.

As used herein, a “target site” or “target nucleic acid sequence” is a nucleic acid sequence that defines a portion of a nucleic acid to which a binding molecule (e.g. a DNA-binding domain disclosed herein) will bind, provided sufficient conditions for binding exist.

The term “expression” with reference to a gene or “gene expression” refers to the conversion of the information, contained in a gene, into a gene product. A gene product can be the direct transcriptional product of a gene (e.g., mRNA, tRNA, rRNA, antisense RNA, ribozyme, structural RNA or any other type of RNA) or can be a protein produced by translation of an mRNA. Gene products also include RNAs which are modified, by processes such as capping, polyadenylation, methylation, and editing, and proteins modified by, for example, methylation, acetylation, phosphorylation, ubiquitination, ADP-ribosylation, myristoylation, and glycosylation. Hence, reference to expression or gene expression includes protein (or polypeptide) expression or expression of a transcribable product of or a gene such as mRNA. The protein expression may include intracellular expression or surface expression of a protein. Typically, expression of a gene product, such as mRNA or protein, is at a level that is detectable in the cell.

As used herein, a “detectable” expression level, means a level that is detectable by standard techniques known to a skilled artisan, and include for example, differential display, RT (reverse transcriptase)-coupled polymerase chain reaction (PCR), Northern Blot, and/or RNase protection analyses as well as immunoaffinity-based methods for protein detection, such as flow cytometry, ELISA, or western blot. The degree of expression levels need only be large enough to be visualized or measured via standard characterization techniques.

As used herein, the term “DNA-targeting system” or “epigenetic-modifying DNA-targeting system” refers to a composition comprising a DNA-binding domain (such as any Cas, ZFN, or TALE-based DNA-binding domain described herein) that targets a target site of a target gene and/or regulatory element thereof. In some embodiments, the DNA-targeting system is engineered to target the target site. In some embodiments, the DNA-targeting system comprises one or more effector domains that modify transcription of the target gene and/or regulatory element thereof when recruited to the target site by the DNA-targeting system. In some embodiments, the DNA-targeting system is capable of targeting more than one target site (i.e. a plurality of target sites), such as 2, 3, 4, 5, 6, or more target sites.

As used herein, the term “DNA-targeting module” refers to any composition or portion of a DNA-targeting system described herein that targets one target site. For example, an individual DNA-targeting module may comprise a fusion protein comprising a DNA-binding domain (e g a ZFN or TALE DNA-binding domain) that targets a target site for a target gene and/or regulatory element thereof, and a transcriptional repressor domain (e.g. KRAB). In other embodiments, a DNA-targeting module comprises (a) a fusion protein comprising a Cas protein and a transcriptional repressor domain, and (b) a gRNA that targets a target site of a target gene and/or regulatory element thereof. A DNA-targeting system provided herein may comprise one or more (such as two) DNA-targeting modules. A DNA-targeting system provided herein may comprise 2 to 10 DNA-targeting modules.

In some embodiments, two DNA-targeting modules of a DNA-targeting system may comprise separate, (i.e. non-overlapping) components. For example, a DNA-targeting system may comprise two different fusion proteins, each fusion protein targeting and repressing a different gene and/or regulatory element thereof. For example, the DNA-targeting system may comprise a first DNA-targeting module comprising a first fusion protein comprising a DNA-binding domain (such as a ZFN or TALE DNA-binding domain) that targets a target site for a first gene and a transcriptional repressor domain, and a second DNA-targeting module comprising a second fusion protein comprising a DNA-binding domain that targets a target site for a second gene and a transcriptional repressor domain. In another example, the DNA-targeting system may comprise a first DNA-targeting module comprising a first fusion protein comprising a DNA-binding domain that targets a target site for a first gene (such as a ZFN or TALE DNA-binding domain) and a transcriptional repressor domain, and a second DNA-targeting module comprising (a) a fusion protein comprising a Cas protein and a transcriptional repressor domain and (b) a gRNA that targets a target site for a second gene. In another example, the DNA-targeting system may comprise a first DNA-targeting module comprising a first fusion protein comprising a first Cas protein and a transcriptional repressor domain, and (b) a first gRNA that complexes with the first Cas protein and targets a target site for a first target gene, and a second DNA-targeting module comprising a second fusion protein comprising a second Cas protein that is different from the first Cas protein and a transcriptional repressor domain, and (b) a second gRNA that complexes with the second Cas protein and targets the second Cas protein to a target site for a second target gene. It will be understood that different Cas protein variants (e.g. SpCas9 and SaCas9) are compatible with different gRNA scaffold sequences and PAMs, as described herein. Thus, it is possible to engineer a single DNA-targeting system comprising multiple non-overlapping CRISPR/Cas-based DNA-targeting modules, each targeting a different target site.

In some embodiments, two DNA-targeting modules of a DNA-targeting system may comprise shared (i.e. overlapping) components. For example, a DNA-targeting system may comprise a first DNA-targeting module comprising (a) a fusion protein comprising a Cas protein and a transcriptional repressor domain, and (b) a gRNA that targets a target site for a first gene or regulatory element thereof, and a second DNA-targeting module comprising (a) the fusion protein of the first DNA-targeting module, and (b) a gRNA that targets a target site for a second gene or regulatory element thereof. It will be understood that providing two or more different gRNAs for a given Cas protein allows different molecules of the same Cas protein to be targeted to the target sites of the two or more gRNAs.

As used herein, the term “reduced expression” or “decreased expression” means any form of expression that is lower than the expression in an original or source cell that does not contain the modification for modulating a particular gene expression by a DNA-targeting system, for instance a wild-type expression level (which can be absence of expression or immeasurable expression as well). Reference herein to “reduced expression,” or “decreased expression” is taken to mean a decrease in gene expression relative to the level in a cell that does not contain the modification, such as the original source cell prior to contacting with, or engineering to introduce, the DNA-binding system into the T cell, such as an unmodified cell or a wild-type T cell. The decrease in expression can be at least 5%, 10%, 20%, 30%, 40% or 50%, 60%, 70%, 80%, 85%, 90%, or 100% or even more. In some cases, the decrease in expression can be at least 2-fold, 5-fold, 10-fold, 20-fold, 30-fold, 40-fold, 50-fold, 60-fold, 70-fold, 80-fold, 90-fold, 100-fold, 200-fold or more.

As used herein, the term “reduced transcription” or “decreased transcription” refers to the level of transcription of a gene that is lower than the transcription of the gene in an original or source cell that does not contain the modification for modulating transcription by a DNA-targeting system, for instance a wild-type transcription level of a gene. Reference to reduced transcription or decreased transcription can refer to reduction in the levels of a transcribable product of a gene such as mRNA. Any of a variety of methods can be used to monitor or quantitate a level of a transcribable product such as mRNA, including but not limited to, real-time quantitative RT (reverse transcriptase)-polymerase chain reaction (qRT-PCR), Northern Blot, microarray analysis, or RNA sequencing (RNA-Seq). The reduction in transcription can be at least 5%, 10%, 20%, 30%, 40% or 50%, 60%, 70%, 80%, 85%, 90%, or 100% or even more.

As used herein, an “epigenetic modification” refers to changes in the gene expression that are not caused by changes in the DNA sequences but are due to events like DNA methylations, histone modifications, miRNA expression modulation.

As used herein, the term “modification” or “modified” with reference to a T cell refers to any change or alteration in a cell that impacts gene expression in the cell. In some embodiments, the modification is an epigenetic modification that directly changes the epigenetic state of a gene or regulatory elements thereof to alter (e.g. decrease) expression of a gene product. In some embodiments, a modification described herein results in decreased expression of a target gene or selected polynucleotide sequence.

As used herein, a “fusion” molecule is a molecule in which two or more subunit molecules are linked, such as covalently. Examples of a fusion molecule include, but are not limited to, fusion proteins (for example, a fusion between a DNA-binding domain such as a ZFP, TALE DNA-binding domain or CRISPR-Cas protein and one or more effector domains, such as a transactivation domain). The fusion molecule also may be part of a system in which a polynucleotide component associates with a polypeptide component to form a functional molecule (e.g., a CRISPR/Cas system in which a single guide RNA associates with a functional domain to modulate gene expression). Fusion molecules also include fusion nucleic acids, for example, a nucleic acid encoding the fusion protein. Expression of a fusion protein in a cell can result from delivery of the fusion protein to the cell or by delivery of a polynucleotide encoding the fusion protein to a cell, where the polynucleotide is transcribed, and the transcript is translated, to generate the fusion protein.

The term “methylation,” as used herein, refers to the presence of epigenetic methylation of cytosine residues in DNA at sites where it is not typically present in normal cells.

The term “vector,” as used herein, refers to a nucleic acid molecule capable of propagating another nucleic acid to which it is linked. The term includes the vector as a self-replicating nucleic acid structure as well as the vector incorporated into the genome of a host cell into which it has been introduced. Certain vectors are capable of directing the expression of nucleic acids to which they are operatively linked. Such vectors are referred to herein as “expression vectors.” Among the vectors are viral vectors, such as adenoviral vectors or lentiviral vectors.

The term “expression vector” refers to a vector comprising a recombinant polynucleotide comprising expression control sequences operatively linked to a nucleotide sequence to be expressed. An expression vector comprises sufficient cis-acting elements for expression; other elements for expression can be supplied by the host cell or in an in vitro expression system. Expression vectors include, but are not limited to, cosmids, plasmids (e.g., naked or contained in liposomes) and viruses (e.g., lentiviruses, retroviruses, adenoviruses, and adeno-associated viruses) that incorporate the recombinant polynucleotide.

The term “isolated” means altered or removed from the natural state. For example, a nucleic acid or a peptide naturally present in a living animal is not “isolated,” but the same nucleic acid or peptide partially or completely separated from the coexisting materials of its natural state is “isolated.” An isolated nucleic acid or protein can exist in substantially purified form, or can exist in a non-native environment such as, for example, a host cell.

The term “polynucleotide” refers to a chain of nucleotides. Furthermore, nucleic acids are polymers of nucleotides. Thus, nucleic acids and polynucleotides as used herein are interchangeable. One skilled in the art has the general knowledge that nucleic acids are polynucleotides, which can be hydrolyzed into the monomelic “nucleotides.” The monomelic nucleotides can be hydrolyzed into nucleosides. As used herein polynucleotides include, but are not limited to, all nucleic acid sequences which are obtained by any means available in the art, including, without limitation, recombinant means, i.e., the cloning of nucleic acid sequences from a recombinant library or a cell genome, using ordinary cloning technology and PCR™, and the like, and by synthetic means.

As used herein, the terms “peptide,” “polypeptide,” and “protein” are used interchangeably, and refer to a compound comprised of amino acid residues covalently linked by peptide bonds. A protein or peptide must contain at least two amino acids, and no limitation is placed on the maximum number of amino acids that can comprise a protein's or peptide's sequence. Polypeptides include any peptide or protein comprising two or more amino acids joined to each other by peptide bonds. As used herein, the term refers to both short chains, which also commonly are referred to in the art as peptides, oligopeptides and oligomers, for example, and to longer chains, which generally are referred to in the art as proteins, of which there are many types. “Polypeptides” include, for example, biologically active fragments, substantially homologous polypeptides, oligopeptides, homodimers, heterodimers, variants of polypeptides, modified polypeptides, derivatives, analogs, fusion proteins, among others. The polypeptides include natural peptides, recombinant peptides, synthetic peptides, or a combination thereof.

As used herein, “percent (%) amino acid sequence identity” and “percent identity” when used with respect to an amino acid sequence (reference polypeptide sequence) is defined as the percentage of amino acid residues in a candidate sequence (e.g., the subject antibody or fragment) that are identical with the amino acid residues in the reference polypeptide sequence, after aligning the sequences and introducing gaps, if necessary, to achieve the maximum percent sequence identity, and not considering any conservative substitutions as part of the sequence identity. Alignment for purposes of determining percent amino acid sequence identity can be achieved in various known ways, in some embodiments, using publicly available computer software such as BLAST, BLAST-2, ALIGN or Megalign (DNASTAR) software. Appropriate parameters for aligning sequences can be determined, including any algorithms needed to achieve maximal alignment over the full length of the sequences being compared.

In some embodiments, “operably linked” may include the association of components, such as a DNA sequence, (e.g. a heterologous nucleic acid) and a regulatory sequence(s), in such a way as to permit gene expression when the appropriate molecules (e.g. transcriptional repressor proteins) are bound to the regulatory sequence. Hence, it means that the components described are in a relationship permitting them to function in their intended manner.

An amino acid substitution may include replacement of one amino acid in a polypeptide with another amino acid. The substitution may be a conservative amino acid substitution or a non-conservative amino acid substitution. Amino acid substitutions may be introduced into a binding molecule, e.g., antibody, of interest and the products screened for a desired activity, e.g., retained/improved antigen binding, decreased immunogenicity, or improved ADCC or CDC.

Amino acids generally can be grouped according to the following common side-chain properties:

• • (1) hydrophobic: Norleucine, Met, Ala, Val, Leu, Ile;
  • (2) neutral hydrophilic: Cys, Ser, Thr, Asn, Gln;
  • (3) acidic: Asp, Glu;
  • (4) basic: His, Lys, Arg;
  • (5) residues that influence chain orientation: Gly, Pro;
  • (6) aromatic: Trp, Tyr, Phe.

In some embodiments, conservative substitutions can involve the exchange of a member of one of these classes for another member of the same class. In some embodiments, non-conservative amino acid substitutions can involve exchanging a member of one of these classes for another class.

As used herein, a composition refers to any mixture of two or more products, substances, or compounds, including cells. It may be a solution, a suspension, liquid, powder, a paste, aqueous, non-aqueous or any combination thereof.

As used herein, a “subject” or an “individual,” which are terms that are used interchangeably, is a mammal. In some embodiments, a “mammal” includes humans, non-human primates, domestic and farm animals, and zoo, sports, or pet animals, such as dogs, horses, rabbits, cattle, pigs, hamsters, gerbils, mice, ferrets, rats, cats, monkeys, etc. In some embodiments, the subject or individual is human. In some embodiments, the subject is a patient that is known or suspected of having a disease, disorder or condition.

As used herein, the term “treating” and “treatment” includes administering to a subject an effective amount of cells (e.g. T cells), such as such cells that have been modified by a DNA-targeting system or polynucleotide(s) encoding the DNA-targeting system described herein, so that the subject has a reduction in at least one symptom of the disease or an improvement in the disease, for example, beneficial or desired clinical results. For purposes of this technology, beneficial or desired clinical results include, but are not limited to, alleviation of one or more symptoms, diminishment of extent of disease, stabilized (i.e., not worsening) state of disease, delay or slowing of disease progression, amelioration or palliation of the disease state, and remission (whether partial or total), whether detectable or undetectable. Treating can refer to prolonging survival as compared to expected survival if not receiving treatment. Thus, one of skill in the art realizes that a treatment may improve the disease condition, but may not be a complete cure for the disease. In some embodiments, one or more symptoms of a disease or disorder are alleviated by at least 5%, at least 10%, at least 20%, at least 30%, at least 40%, or at least 50% upon treatment of the disease.

The term “therapeutically effective amount” refers to the amount of the subject compound that will elicit the biological or medical response of a tissue, system, or subject that is being sought by the researcher, veterinarian, medical doctor or other clinician. The term “therapeutically effective amount” includes that amount of a biological molecule, such as a compound or cells, that, when administered, is sufficient to prevent development of, or alleviate to some extent, one or more of the signs or symptoms of the disorder or disease being treated. The therapeutically effective amount will vary depending on the biological molecule, the disease and its severity and the age, weight, etc., of the subject to be treated.

VIII. EXAMPLES

The following examples are included for illustrative purposes only and are not intended to limit the scope of the invention.

Example 1: Design of gRNAs Targeting Hepatitis B Viral Genes and Regulatory Element Thereof Associated with Viral Replication and Transcription

gRNAs were designed for targeting Hepatitis B viral (HBV) genes and regulatory element thereof associated with viral replication and transcription.

Computational analysis was used to generate a master gRNA protospacer list (target sites) from 6939 different HBV genomes (genotypes A-E). The master gRNA list contained all 110, 438 unique protospacer-PAM sequences (target sites) found across all the genomes (defined by “[N](×20)-NGG”). Next, the protospacer sequences (target sites) were aligned back to all the 6939 HBV genomes. The protospacer sequences were then organized into three categories based on homology and mismatches in the 12 bases on the 5′ end of the protospacer adjacent motif (PAM), as represented by ‘n’ in ‘nnnnnnnnnnnnn-NGG’: 1) protospacer present with no mismatches (HBV0), 2) protospacer present if one mismatch was allowed (HBV1), and 3) protospacer present if up to two mismatches were allowed (HBV2).

For every protospacer sequence, each of these three scores was generated. The scores represented the probability that for a given HBV genome, the protospacer would be present and active given the specific tolerances for mismatches in the 5′-end of the PAM. Multiple variants were found to be present on the same core protospacer-PAM sequence in the analysis. Therefore, the protospacer sequence list was further grouped based on the core protospacer-PAM sequence (NNNNNNNN-NGG). Finally, the protospacer sequence in each group with the highest perfect genome alignment score (homology) was chosen as the candidate gRNA for a given core protospacer-PAM sequence. The screening candidate spacers with more than 90% HBV genomic conservation and no mismatches (HBV0) are shown in Table E1. The screening candidate gRNA spacers with more than 90% HBV genomic conservation and 1-2 mismatches (HBV1) are shown in Table E1. The screening candidate gRNA spacers with 70-90% HBV genomic conservation and up to 2 mismatches (HBV2) are shown in Table E1. Each gRNA further comprised a scaffold sequence for SpCas9, comprising the sequence:

Example 2: Identification of gRNAs for Targeted Transcriptional Repression of Genes and Regulatory Elements Thereof Associated with Viral Replication and Transcription

gRNAs were identified that facilitate transcriptional repression of targeted genes within the HBV genome present in either integrated HBV DNA and in covalently closed circular DNA (cccDNA) or relaxed circular DNA (rcDNA), as part of a DNA-targeting system comprising the gRNA and a dCas9-effector fusion protein. FIGS. 1 and 4 depict the median targeting positions of each gRNAs across the HBV genome.

1) Transient Arrayed Screening for Modulators of the Integrated HBV Genome

A. Short Interval (5-Day) Screen Using dCas9-KRAB

Guide RNAs targeting genes and regulatory elements thereof associated with HBV transcription, including those listed in Tables E1-E3 and Table 6, were transfected into Hep3B cells expressing HBV from integrated sequences only (without cccDNA), together with an mRNA encoding a dSpCas9-KRAB fusion protein (SEQ ID NO:594) for transcriptional repression of gRNA-targeted genes.

Other cell lines such as immortalized HBV infected human hepatocyte cell lines (Hep3B, PLC/PRF/5), engineered hepatocyte cell lines that contain a transgene copy of the HBV genome (HepG2.2.15, HepAD38), or engineered immortalized hepatocyte lines that overexpress the cognate surface receptor required for HBV entry (HepG2.NTCP) may be considered, together with a dSpCas9-effector fusion protein for simultaneous transcriptional repression of one or more gRNA-targeted genes. Additionally, to increase repression of HBV replication and transcription a combination of multiple exemplary gRNAs from Tables E1-E3 and Table 6, either targeting the same or different HBV viral genes may be delivered in a multiplexed approach.

Transfected cells were assessed on day 5 for transcriptional repression of the targeted HBV transcripts by qRT-PCR measurement of either HBsAg transcript or total HBV RNA transcript levels (FIGS. 1 and 3). Transfected cells may also be assessed for transcriptional repression by ELISA for reduction in Hepatitis B Surface Antigen (HBsAg) levels from integrated and cccDNA as well as Hepatitis B Virus core related-Antigen Protein (HBcrAg) levels from cccDNA only. gRNAs mediating repression resulting in reduction of HBsAg by 90% and HBeAg by 50% may be identified for further analysis.

FIG. 1 depicts the log fold change in HBV RNA for each gRNA in Hep3B cells following delivery alongside dCas9-KRAB. The x-axis depicts the median targeting positions of each gRNAs across the HBV genome. As shown in FIG. 1, sites targeted by 94 out of 192 gRNAs (“Any repression”, depicted using arrow) showed repression of total HBV RNA. The “hit” gRNAs identified targeted the polymerase, S, short X, or the pre-core genes. Sites targeted by 48 out of the 192 gRNAs (“>75% repression”, depicted using arrow) showed more than 75% repression of total HBV RNA. Guide RNAs set forth in SEQ ID NOS: 565 (HBVg_175), 528 (HBVg_138), 582 (HBVg_192), 542 (HBVg_152), 508 (HBVg_118), 515 (HBVg_125), 575 (HBVg_185), 453 (HBVg_63), 506 (HBVg_116), 514 (HBVg_124), 395 (HBVg_5), 472 (HBVg_82), 451 (HBVg_61), 488 (HBVg_98), 540 (HBVg_150), 533 (HBVg_143), 572 (HBVg_182), 566 (HBVg_176), 489 (HBVg_99), 469 (HBVg_79), 408 (HBVg_18), 465 (HBVg_75), 402 (HBVg_12), 474 (HBVg_84), 525 (HBVg_135), 416 (HBVg_26), 369 (HBVg_6), 554 (HBVg_164), 419 (HBVg_29), 545 (HBVg_155), 446 (HBVg_56), 580 (HBVg_190), 555 (HBVg_165), 412 (HBVg_22), 428 (HBVg_38), 458 (HBVg_68), 548 (HBVg_158), 511 (HBVg_121), 432 (HBVg_42), 441 (HBVg_51), 433 (HBVg_43), 579 (HBVg_189), 479 (HBVg_89), 478 (HBVg_88), 520 (HBVg_130), 462 (HBVg_72), 523 (HBVg_133), and 503 (HBVg_113) mediated more than 75% repression of total HBV RNA. Furthermore, sites targeted by 10 out of the 192 gRNAs (“>90% repression”, depicted using arrow) showed more than 90% repression of total HBV RNA (up to 98.5%).

Specifically, more than 90% repression of total HBV RNA was observed with gRNAs targeting the M/S-HBs promoter, Enh1/X-promoter, Enh2/Basal core promoter, L-HBs promoter or the M/S-gene promoter regions. Guide RNAs set forth in SEQ ID NOs: 565, 528, 582, 542, 508, 515, 575, 453, 506, 514, 425, or 472 mediated more than 90% repression of total HBV RNA.

The gRNAs (SEQ ID NOS: 528 (HBVg_138), 582 (HBVg_192), 565 (HBVg_175), 453 (HBVg_63) with the highest transcriptional repression of total HBV RNA targeted the L-HBs promoter and Enh1/X-promoter regions (HBV median positions: 3197 bp (HBVg_138), 1124 bp (HBVg_192), 3179 bp (HBVg_175), and 1288 bp (HBVg_63) of the HBV genome corresponding to positions with reference to the Hepatitis B Virus genome (Hepatitis B virus subtype ayw, complete genome, GenBank: U95551.1), SEQ ID NO: 650) (FIG. 3A). The median position comprises the average position across all HBV genotypes. For instance, the median position comprises the average position of HBV genomes comprising sequences set forth in SEQ ID NOS: 650, 678, and 679. The gRNAs (SEQ ID NOS: 528 (HBVg_138), 582 (HBVg_192), 453 (HBVg_63), and 489 (HBVg_99) with the highest transcriptional repression of HBsAg RNA targeted the Enh1/X-promoter, Enh2/basal core promoter, and L-HBs promoter regions (HBV median positions: 3197 bp (HBVg_138), 1124 bp (HBVg_192), 1288 bp (HBVg_63,), 1850 bp (HBVg_99), and 1904 bp (HBVg_79), of the HBV genome corresponding to positions with reference to the Hepatitis B Virus genome (Hepatitis B virus subtype ayw, complete genome, GenBank: U95551.1), SEQ ID NO: 650) (FIG. 3B).

B. Long Interval Therapeutically Relevant Screen Using DNMT3A/L-dSpCas9-KRAB

Guide RNAs targeting genes and regulatory elements thereof associated with HBV transcription, including those listed in Tables E1-3 and Table 6, were transfected into Hep3B cells expressing HBV from integrated sequences only (without cccDNA), together with an mRNA encoding a DNMT3A/L-dSpCas9-KRAB fusion protein (SEQ ID NO: 644) for transcriptional repression of gRNA-targeted genes.

Other cell lines such as immortalized HBV infected human hepatocyte cell lines (Hep3B, PLC/PRF/5), engineered hepatocyte cell lines that contain a transgene copy of the HBV genome (HepG2.2.15, HepAD38), or engineered immortalized hepatocyte lines that overexpress the cognate surface receptor required for HBV entry (HepG2.NTCP) may be considered, together with an mRNA encoding the dSpCas9-effector fusion protein for simultaneous transcriptional repression of one or more gRNA-targeted genes. Additionally, to increase repression of HBV replication and transcription a combination of multiple exemplary gRNAs from Table E1 and Table 6, either targeting the same or different HBV viral genes may be delivered in a multiplexed approach.

Transfected cells were assessed on days 41 and 61 for transcriptional repression of the targeted HBV transcripts by qRT-PCR measurement of total HBV RNA transcript levels (FIGS. 4 and 5). Transfected cells may also be assessed for transcriptional repression by ELISA for reduction in Hepatitis B Surface Antigen (HBsAg) levels from integrated and cccDNA as well as Hepatitis B Virus core related-Antigen Protein (HBcrAg) levels from cccDNA only. gRNAs mediating repression resulting in reduction of total HBV RNA transcript levels by at least 80% were identified for further analysis.

FIG. 4 depicts the log fold change in HBV RNA for each gRNA on day 61. The x-axis depicts the median targeting positions of each gRNAs across the HBV genome. The gRNAs identified targeted the polymerase, S, short X, or the pre-core genes. Specifically, more than 80% repression of total HBV RNA was observed with gRNAs targeting the pre-S1 promoter, pre-S2 promoter, and the polymerase gene.

The gRNAs (HBVg_142; SEQ ID NO: 532, HBVg_138; SEQ ID NO: 528, HBVg_185: SEQ ID NO: 575, HBVg_26: SEQ ID NO: 416, and HBVg_152; SEQ ID NO: 542) with the highest transcriptional repression of total HBV RNA targeted the pre-S1 promoter, pre-S2 promoter, CpG island 1, and the polymerase genes (Median positions: 3016 bp (HBVg_142), 3197 bp (HBVg_138), 341 bp (HBVg_185), 55 bp (HBVg_26), and 340 bp (HBVg_152) of the HBV genome corresponding to positions with reference to the Hepatitis B Virus genome (Hepatitis B virus subtype ayw, complete genome, GenBank: U95551.1), SEQ ID NO: 650) (FIG. 5). Surprisingly, transcriptional repression of at least 80% persisted until 41- and 61-days post-transfection, indicating long lasting efficacy of the epigenetic editing, as the dCas9 fusion protein is no longer expressed by these late timepoints.

Transfected cells were also assessed for transcriptional repression of the targeted HBV transcripts at longer timepoints by qRT-PCR measurement of total HBV RNA transcript levels (FIGS. 6A-6B). Multiple gRNAs as set forth in SEQ ID NOs: 453 (HBVg_63), 575 (HBVg_185), 446 (HBVg_56), 412 (HBVg_22), and 416 (HBVg_26) showed therapeutically viable repression levels of integrated HBV RNA after 248 days and more than 120 cell doublings. Stable repression in total HBV RNA was achieved after a single dose of gRNA.

Transfected cells from day 222 of the study were re-transfected with the same gRNA or non-targeting gRNA and the mRNA encoding DNMT3A/L-dSpCas9-KRAB fusion protein (SEQ ID NO: 644) using lipofectamine MessengerMax. Total HBV RNA levels were examined four days after transfection to evaluate improvement in repression upon redosing. Guide RNAs HBVg_22 (SEQ ID NO: 412), HBVg26 (SEQ ID NO: 416), HBVg_185 (SEQ ID NO: 575), and HBVg_63 (SEQ ID NO: 453) showed significant repression after the first dose and showed further marked reductions in HBV RNA levels after redosing (FIG. 7). The effect was sustained as full repression for a given dose was reached. Near complete repression was achieved (95% bulk RNA) in almost all cells (˜96%) once delivery was corrected for. Non-targeting gRNAs did not significantly affect repression levels as compared to non-treated control cells. Further studies to evaluate redosing at lower baseline delivery levels may be performed. Delivery and re-dosing in primary human hepatocytes and mouse models may be optimized.

II) Transient Arrayed Screening for Modulators of Episomal cccDNA in a True Infection Model

HepG2.NTCP cells dosed with HBV at 100 GE/cell were treated with control or standard of care treatment (e.g., nucleoside analogs such as Entecavir (ETV)) three days post HBV infection. HepG2.NTCP cells enable a true infection model of HBV as the HBV infection is sustained due to the generation and presence of native cccDNA. Six days after HBV infection, gRNAs targeting genes and regulatory elements thereof associated with HBV transcription, including those listed in Tables E1-E3 and Table 6, were transfected via lipofection into the cells expressing HBV from cccDNA together with an mRNA encoding the DNMT3A/L-dSpCas9-KRAB fusion protein (SEQ ID NO: 644) for transcriptional repression of gRNA-targeted HBV genes.

Transfected cells were harvested and assessed on day 5 for transcriptional repression of the targeted HBV transcripts (either Total HBV RNA or 3.5 kB HBV RNAs). Measurements of 3.5 kb total HBV RNA transcript levels was performed via qRT-PCR, with one representative run shown (FIG. 8). Transfected cells may also be assessed for transcriptional repression by ELISA for reduction in Hepatitis B Surface Antigen (HBsAg) levels and Hepatitis B Virus core related-Antigen Protein (HBcrAg) levels from cccDNA. gRNAs were identified that mediated repression resulting in reduction of 3.5 kb total HBV RNA transcript levels by at least 80%.

FIG. 8 depicts the log fold change in 3.5 kb total HBV RNA for each gRNA from one replicate of the screen. The x-axis depicts the median targeting positions of each gRNA across the HBV genome. The gRNAs (HBVg_45: SEQ ID NO: 435, HBVg_22; SEQ ID NO: 412, HBVg_456: SEQ ID NO: 66, HBVg_6; SEQ ID NO: 396, HBVg_34: SEQ ID NO: 424, HBVg_182: SEQ ID NO: 572) with the highest transcriptional repression of 3.5 kb total HBV RNA targeted Enhancer 1/X promoter region and the Enhancer II regulatory element (HBV median position: 1580 bp (HBVg_45), (97.5%)), the polymerase gene and CpG island 2 (HBV median positions: 1283 bp (HBVg_22) (93.0%) and 1162 bp (HBVg_66) (90.4%)), and the polymerase gene and CpG island 1 (HBV median positions: 261 bp (HBVg_6, and/or HBVg_34) (89.8%) and 349 bp (HBVg_182) (89.7%)).

A correlation plot of the cccDNA screen (rep #3) to another cccDNA screen (rep #2) showed infection-to-infection consistency (FIG. 9). gRNAs were identified that either repressed integrated HBV, cccDNA, or both integrated and cccDNA (FIG. 10). Finally, gRNAs were identified that achieved multiplexed HBV repression from a single gRNA. FIG. 11 lists sequences targeted by single gRNAs that achieved repression of multiple genes and regulatory elements (e.g., HBs/CpG Island 1, HBx/Enh1 enhancer/CpG Island 2). The repression was achieved within the integrated HBV DNA and cccDNA HBV genomes with high combined efficiencies. FIG. 12 lists sequences targeted by gRNAs (HBVg_22; SEQ ID NO: 412, HBVg_63; SEQ ID NO: 453, HBVg_185; SEQ ID NO: 575, HBVg_99: SEQ ID NO: 489), that achieve durable repression across multiple HBV transcripts (both integrated and cccDNA HBV depots). The repression is effective following a single transient delivery of mRNA/gRNA. These single gRNAs may be used in combination for multiplexed approaches.

Transfected cells were also harvested and assessed on day 14, a later timepoint, for transcriptional repression of the targeted HBV transcripts. Measurements of 3.5 kb total HBV RNA transcript levels was performed via qRT-PCR (FIG. 13). Transfected cells may also be assessed for transcriptional repression by ELISA for reduction in Hepatitis B Surface Antigen (HBsAg) levels and Hepatitis B Virus core related-Antigen Protein (HbcrAg) levels from cccDNA. FIG. 13 depicts the log fold change in 3.5 kb HBV RNA for each gRNA. The x-axis depicts the median targeting positions of each gRNA across the HBV genome. Multiple gRNAs (28/189) were identified that mediated repression of over 80% and up to 97.2% of the 3.5 kb HBV cccDNA. The gRNAs identified were HBVg_73 (SEQ ID NO: 463), HBVg_192 (SEQ ID NO: 582), HBVg_18 (SEQ ID NO: 408), HBVg_63 (SEQ ID NO: 453), HBVg_22 (SEQ ID NO: 412), HBVg_185 (SEQ ID NO: 575), HBVg_46 (SEQ ID NO: 436), HBVg_99 (SEQ ID NO: 489), HBVg_162 (SEQ ID NO: 552), HBVg_174 (SEQ ID NO: 568), HBVg_20 (SEQ ID NO: 410), HBVg_79 (SEQ ID NO: 469), HBVg_50 (SEQ ID NO: 440), HBVg_79 (SEQ ID NO: 469), HBVg_50 (440), HBVg_27 (SEQ ID NO: 417), HBVg_182 (SEQ ID NO: 572), and HBVg_12 (SEQ ID NO: 402).

FIG. 14 shows repression of the targeted HBV cccDNA transcripts by single gRNAs HBVg_73 (SEQ ID NO: 463), HBVg_192 (SEQ ID NO: 582), HBVg_18 (SEQ ID NO: 408), HBVg_63 (SEQ ID NO: 456), HBVg_22 (SEQ ID NO: 412), HBVg_185 (SEQ ID NO: 575), HBVg_46 (SEQ ID NO: 436), HBVg_99 (SEQ ID NO: 489), HBVg_162 (SEQ ID NO: 552), HBVg_174 (SEQ ID NO: 564), HBVg_5 (SEQ ID NO: 410), HBVg_79 (SEQ ID NO: 469), HBVg_50 (SEQ ID NO: 440), HBVg_27 (SEQ ID NO: 417), HBVg_66 (SEQ ID NO: 456), and HBVg_182 (SEQ ID NO: 572). The sites targeted by the gRNAs were also 92% conserved across HBV genotypes. Guide RNAs HBVg_73 (SEQ ID NO: 463) (93%), HBVg_192 (SEQ ID NO: 582) (91.9%), and HBVg_18 (SEQ ID NO: 408) (91.8%) mediated the highest repression.

Example 3: Strong Repression of cccDNA Achieved in Primary Human Hepatocyte (PHH) Infection Models

To evaluate the gRNA mediated epi-editing in a more native context, primary human hepatocyte (PHH) infection models were used. Primary human hepatocytes from two donors (PHH Donor 1 and PHH Donor 2) were used for these experiments, with both donors infected with HBV at 100 GE/cell and infection allowed to develop for five days in culture. The cells were then transfected with mRNA encoding DNMT3A/L-dSpCas9-KRAB (SEQ ID NO: 644) and gRNA HBVg_22 (SEQ ID NO:412) and evaluated for repression via RNA isolation and qPCR. FIG. 15A shows repression of HBV RNA in both donors on day 7 and day 13/14. PHH donor 2 supported approximately 5 times higher levels of infection at baseline as compared to PHH donor 1 at the same dose. Despite the large differences in delivery efficiencies, both PHH donors showed strong and durable cccDNA repression with HBVg_22 (SEQ ID NO: 412).

Primary human hepatocytes from donor 1 were seeded on two collagen-coated 24-well plates at 0.2×10⁶ cells/cm². Twenty-four hours post seeding, cells were infected with HBV at 100 GE/cell and 200 GE/cell and evaluated for infection via RNA isolation and qPCR of the 3.5 kb HBV transcript. The cells were then transfected with mRNA encoding DNMT3A/L-dSpCas9-KRAB (SEQ ID NO: 644) and gRNA (SEQ ID NO:412) and were evaluated for repression after six days via RNA isolation and qPCR. FIG. 15B shows strong repression in the PHH infection models infected with low dose HBV (1×3.5 kb HBV transcript basally) and high dose HBV (12×3.5 kb transcript basally). The results show that significant repression was achieved in both low and high dose groups. The repression was maintained across a large window of HBV RNA expression (12-fold between both doses).

Example 4: Comparison Between Repression Induced by dSpCas9-KRAB and DNMT3A/L-dSpCas9-KRAB Fusion Proteins

To compare the repression induced by dSpCas9-KRAB and DNMT3A/L-dSpCas9-KRAB fusion proteins, HepG2.NTCP and PxB PHH cells were transfected with mRNA encoding HBVg_22 (SEQ ID NO: 412) in combination with either dSpCas9-KRAB alone (SEQ ID NO:595) or DNMT3A/L-dSpCas9-KRAB (“D3AL-K”; SEQ ID NO: 645). The cells were evaluated for repression after either 20 days or 14 days via RNA isolation and qPCR. FIG. 16A-16B shows a comparison between repression induced by HBVg_22 (SEQ ID NO: 412) in combination with either dSpCas9-KRAB alone (SEQ ID NO:595) or DNMT3A/L-dSpCas9-KRAB (“D3AL-K”; SEQ ID NO: 645) fusion in HepG2.NTCP and PxB PHH models. Transient delivery of dCas9-KRAB alone can engender long-term repression of cccDNA across multiple cell contexts. However, transient delivery of dCas9-KRAB alone does not enable long-term repression of integrated HBV DNA. This shows that methylation (e.g., by D3AL-K) is required for durable transcriptional repression of HBV RNA from HBV integrants, and some degree of durable cccDNA silencing can be achieved without DNMTR3A/3L domains.

Example 5: Multiplexed Targeted Transcriptional Repression for Promoting Phenotypes for Silencing HBV Replication and Expression

DNA-targeting systems comprising different combinations of the gRNAs identified in Example 2 were screened to identify conditions in which multiplexed targeted transcriptional repression of at least two genes or regulatory elements thereof promotes phenotypes for silencing HBV replication and expression.

DNA-targeting systems comprising gRNAs and an mRNA encoding a dSpCas9-effector are transiently transfected into cell lines expressing HBV from integrated sequences and cccDNA. gRNAs are transfected individually, or in combinations of 2 gRNAs, 3 gRNAs, or 4 gRNAs, with each gRNA targeting a different gene or regulatory elements. Alternatively, gRNAs are transfected individually, or in combinations of 2 gRNAs, 3 gRNAs, or 4 gRNAs, with each gRNA targeting a different target site within the same gene or regulatory element.

In one example, a combination of 2 gRNAs comprises a first gRNA targeting one of Enh1/X-promoter, Enh2/Basal core promoter, L-HBs promoter, M/S-HBs promoter, and a second gRNA targeting one of Enh1/X-promoter, Enh2/Basal core promoter, L-HBs promoter, and M/S-HBs promoter, wherein the first and second gRNA target different regulatory elements. In another example, a combination of 2 gRNAs comprises a first gRNA targeting Enh1/X-promoter and a second gRNA targeting one of Enh2/Basal core promoter, L-HBs promoter, and M/S-HBs promoter. In another example, a combination of 2 gRNAs comprises a first gRNA targeting Enh1/X-promoter and a second gRNA targeting L-HBs promoter.

In another example, a combination of 3 gRNAs comprises a first gRNA targeting one of Enh1/X-promoter, Enh2/Basal core promoter, L-HBs promoter, and M/S-HBs promoter, a second gRNA targeting one of Enh1/X-promoter, Enh2/Basal core promoter, L-HBs promoter, and M/S-HBs promoter, and a third gRNA targeting one of Enh1/X-promoter, Enh2/Basal core promoter, L-HBs promoter, wherein the second and third gRNA each target a different regulatory element. In another example, a combination of 3 gRNAs comprises a first gRNA targeting Enh1/X-promoter, a second gRNA targeting a Enh2/Basal core promoter, and a third gRNA targeting L-HBs promoter.

In another example, a combination of 4 gRNAs comprises a first gRNA targeting one of Enh1/X-promoter, Enh2/Basal core promoter, L-HBs promoter, and M/S-HBs promoter, a second gRNA targeting one of Enh1/X-promoter, Enh2/Basal core promoter, L-HBs promoter, and M/S-HBs promoter, a third gRNA targeting one of Enh1/X-promoter, Enh2/Basal core promoter, L-HBs promoter, and a fourth gRNA targeting one of Enh1/X-promoter, Enh2/Basal core promoter, L-HBs promoter, wherein the first, second, third, and fourth gRNA targets a different regulatory element.

In another example, a combination of 3 gRNAs comprises a first gRNA targeting one of L-HBs promoter, and M/S-HBs promoter, a second gRNA targeting the Enh2/Basal core promoter, and a third gRNA targeting the Enh1/X-promoter.

In another example, a combination of 4 gRNAs comprises gRNAs targeting each of the L-HBs and M/S-HBs promoters, and a gRNA targeting the Enh2/Basal core promoter.

Following transfection, cells are assessed for phenotypes that could promote phenotypes for silencing HBV replication and expression. Specifically, transfected cells are assessed for transcriptional repression of the targeted HBV transcripts by qRT-PCR measurement of total HBV RNA transcript levels or 3.5 kb HBV RNA transcript levels. In addition, conditions are identified in which multiplexed targeted repression of a combination of genes and/or regulatory elements thereof (e.g. Enh1/X-promoter and L-HBs promoter) leads to reduced HBV RNA than targeted repression of any individual gene of the combination alone (e.g. Enh1/X-promoter alone or L-HBs promoter alone).

DNA-targeting systems with combinations of gRNAs are identified that mediate multiplexed targeted transcriptional repression to silence HBV replication and expression.

FIG. 17 shows combinations of gRNAs that mediate multiplexed targeted transcriptional repression of different regions within the HBV RNA in Hep3B cells. Multiple gRNAs that mediated the most repression were pooled and compared to repression induced by single gRNAs (e.g., “best single gRNAs” such as HBVg_26, HBVg_63, HBVg_29, and HBVg_121) and non-targeted gRNAs. The gRNAs were transfected via lipofection with standard dose (20 ng) pooled to maintain a 1× dosage (e.g., “pooled top gRNAs”=1×/4=5 ng per, or “all 16 gRNAs”=1×/16=1.25 ng per) for high expression. As shown in FIG. 17, gRNAs targeting different regions mediated repression as compared to the non-targeting control. However, combinations of multiple gRNAs did not always significantly improve repression as compared to single gRNAs. For example, HBVg_26 (SEQ ID NO: 416) alone mediated comparable repression as compared to a pool of top gRNAs (a combination of HBVg_26 (SEQ ID NO: 416), HBVg_182 (SEQ ID NO: 572), HBVg_185 (SEQ ID NO: 575), and HBVg_152 (SEQ ID NO: 542)) in the M/S-HBs promoter region. However, a pool of the top gRNA at the L-HBs promoter, or a pool with the top single gRNA from each promoter was able to increase repression relative to the best single gRNA from the L-HBs promoter. Together this highlights the context sensitivity for multiplexing gRNA in relation to HBV repression.

Combinations of gRNAs were tested for multiplexed transcriptional repression in a PLC/PRF/5 (Alexander) cell model with poor lipofection capacity. PLC/PRF/5 is a human liver cancer cell line that produces all isoforms of hepatitis B virus surface antigen (HbsAg), including L-HBs, M-HBs, and S-HBs. The cell line contains 8-10 integrations of the HBV as compared to approximately 2 integrations and M/S-HBs isoforms in Hep3B cells. Fourteen days post lipofection with an mRNA encoding D3AL-K and various gRNA combinations, RNA was harvested and a qPCR was run for Total HBV RNA. FIG. 18 shows that HBVg_22 (SEQ ID NO: 412) alone mediated the greatest repression at day 14, followed by HBVg_63 (SEQ ID NO: 453) and HBVg_20 (SEQ ID NO: 410). Many gRNAs do not have functional targeting in these cells. Multiplexing gRNAs did not significantly improve (or hinder) repression as compared to HBVg_22 (SEQ ID NO: 412) alone.

In another multiplexed assay, PXB primary human hepatocytes (PHH) cells were infected with HBV at a multiplicity of infection (MOI) of 100 and allowed to progress for five days. The cells were then lipofected with DNMT3A/L-dSpCas9-KRAB (SEQ ID NO: 644) and various multiplexed gRNA mixtures, such that each gRNA was dosed at 0.5×. Repression of pgRNA was assayed at day 7 and day 14 post-lipofection. FIG. 19 shows comparable durability of multiplexed targeted transcriptional repression mediated by HBVg_22 (SEQ ID NO: 412), HBVg_185 (SEQ ID NO: 575), and HBVg_26 (SEQ ID NO: 416).

Example 6. On-Target Methylation of cccDNA and Integrated HBV DNA

To evaluate target specificity, HepG2.NTCP cells were transfected with either lipid only control, non-targeting gRNA control with an mRNA encoding either a DNMT3A/L-dSpCas9-KRAB fusion construct (SEQ ID NO: 644), dSpCas9-KRAB construct (SEQ ID NO: 594) with a gRNA (demethylase-null control), or with the DNMT3A/L-dSpCas9-KRAB fusion construct (SEQ ID NO: 644) in combination with a gRNA, at maximum dose (FIGS. 20A and B). Methyl capture sequencing using a custom HBV Methylome library was performed three days after lipofection. As seen in FIG. 20A, little to no methylation was seen in the lipid only, non-targeting, and demethylase-null controls. However, the DNMT3A/L-dSpCas9-KRAB fusion (SEQ ID NO: 644) in combination with various gRNAs (FIG. 20B) showed targeted and distinct patters of methylation across the HBV genome in unenriched total HBV DNA pool. Methyl sequencing confirmed specific and robust methylation pattern deposited by the DNMT3A/L-dSpCas9-KRAB fusion protein across the HBV genome. FIG. 21 shows increased methylation patterns in integrated HBV DNA following delivery of mRNA encoding DNMT3A/L-dSpCas9-KRAB along with various gRNA (HBVg_22 (SEQ ID NO: 412), HBVg_26 (SEQ ID NO: 416), HBVg_63 (SEQ ID NO: 453), HBVg_185 (SEQ ID NO: 575) in Hep3B cells. These methylation patterns showed similar trends across the HBV genome to those seen in cccDNA in FIG. 20B. FIG. 22 shows methylation patterns following nuclei isolation in HBV-infected PHH donor #1 (100 Ge/cell) following transient lipofection with HBVg_22 (SEQ ID NO: 412) and mRNA encoding D3AL-K. This isolation of nuclei prior to Methyl-seq reduces rcDNA contamination in the preps and allows for enrichment of the cccDNA signal (55% of HBV DNA captured). This methylation data is similar to other patterns seen for HBVg_22 (SEQ ID NO: 412), and highlights the durability of these epi-genetic changes over time.

Following lipofection of various HBV targeting gRNAs and mRNA at the maximum dose in HepG2.NTCP cells without viral infection, RNA sequencing was performed to assess differential changes to gene expression in non-targeted regions. FIG. 23A depicts a comparison of the epi-editor DNMT3A/L-dSpCas9-KRAB fusion (SEQ ID NO: 645) with targeting gRNAs versus epi-editor DNMT3A/L-dSpCas9-KRAB fusion (SEQ ID NO: 645) with non-targeting gRNAs. The results show no significantly altered gene expression relative to control non-targeting gRNA as a result of the gRNA HBVg_22 (SEQ ID NO: 412) three days post lipofection. FIG. 23B depicts a comparison of the epi-methylation-mediated effects by comparing differentially expressed transcripts following delivery of HBVg_22 (SEQ ID NO: 412) with either an mRNA encoding D3AL-K (SEQ ID NO: 644) or without the DNMT3A/3L domain (dCas9-KRAB, SEQ ID NO: 594), showing effectively no D3AL-mediated changes to gene expression. FIG. 23C shows minimal changes in differentially-expressed genes (DEG) mediated by the gRNAs three days post-lipofection. Most observed changes were shared across more than one gRNA (“Shared DEG”) and were usually transient cell responses to RNA delivery and innate immune response related genes. A majority of the candidate gRNAs analyzed imparted minimal to no off-target differential expression with similarly low levels of off-target gene expression compared to that of a non-targeting gRNA. Additionally, LNPs encapsulating an mRNA encoding DNMT3A/L-dCas9-KRAB along with either HBVg_22 (SEQ ID NO: 412) or a non-targeting gRNA were delivered to primary human hepatocytes at 3 different levels (50 ng, 250 ng, 500 ng per well in a 24 well-plate). Following delivery of these LNPs, RNA was harvested from PHHs at Day 5 and Day 19 post-lipofection and RNA-sequencing was performed. These results showed no differentially expressed genes ([FDR<0.01, abs(L2FC)>1]) between non-targeting gRNA and HBVg_22 (SEQ ID NO: 412) at any dosage or timepoint (FIG. 23D). Very few transcriptional changes were seen relative to carrier-only PHH—HBVg_22 (SEQ ID NO: 412) performs similar to non-targeting control gRNA, and there was only one differentially-expressed gene remaining at Day 19 at the highest dosage.

Example 7: In Vivo Evaluation of HBV Repression in Human Chimeric Liver Mouse Study of HepB

In this Example, a human chimeric liver mouse model (FRG) with high engraftment of human cells into the mouse liver was used. In this mouse model, mice were engrafted with human hepatocytes (more than 70% humanization) and then infected with HBV. The mouse model has several advantages including, presence of a true cccDNA with the native structure, human intracellular epigenetic machinery to interact with the epi-editor, a human genomic background, and reproduction of biologically relevant endpoints (HBV DNA, HBsAg, HBeAg) used in clinical trials.

Mice were infected with approximately 1×10⁸ HBV genomes via tail vein injections. As shown in FIG. 24, the viral infection was allowed to continue until a plateau phase of HBV DNA was reached (1-2 months post tail vein injection). The plateau phase is an indication that a chronic stabilized infection, comprising mostly cccDNA, with a very sparse degree of HBV integrations, has been established.

Once the chronic stabilized infection was established, the mice were dosed with standard of care treatment (e.g., nucleoside analog such as Entecavir, “ETV”) with 1 μg/ml ETV added to drinking water. At day 81, the mice were administered either a) a combination of exemplary epi-editor mRNA with non-targeting gRNA or b) a combination of exemplary epi-editor mRNA and gRNA(s) targeting the HBV genome. The mice were dosed with a single gRNA or multiple gRNAs targeting the same or different genes in a multiplexed approach (as described in Example 4). Mice were grouped into cohorts and administered either 1) non-targeting gRNA (nt1) (n=9), 2) gRNA targeting HBx HBVg_22 (SEQ ID NO: 412) (n=9), 3) GalNAc-conjugated LNPs carrying gRNA HBVg_22 (SEQ ID NO: 412) (n=3), 4) gRNA targeting HBs HBVg_185 (SEQ ID NO: 575) (n=7), 5) gRNA HBVg_22 (SEQ ID NO: 412) and HBVg_185 (SEQ ID NO: 575) (n=7), 6) gRNA HBVg_73 (SEQ ID NO: 463) and 7) non targeting gRNA (nt1) (n=7), 8) gRNA HBVg_22 (SEQ ID NO: 412) (n=7). The combination of epi-editor mRNA (either DNMT3A/L-dCas9-KRAB (SEQ ID NO: 644) or dSpCas9-KRAB construct (SEQ ID NO: 594) for groups 7/8) and gRNAs were delivered at 2 milligrams per kilogram (mpk) doses via lipid nanoparticle delivery systems and RO injection, which allowed for delivery to only 50-60% of the human hepatocytes on average (as determined by protein immune-labeling). N-Acetylgalactosamine (GalNAc) conjugated-LNP in group 3) was administered to improve delivery of the LNP to the hepatocytes in the FRG mouse model. All subjects were assessed with serum draws as indicated and at the study endpoint (Day 130). The mice were evaluated for repression by monitoring the levels of HBV biomarkers, including HBV pre-genomic RNA (pgRNA), total HBV DNA in serum, HBeAg proteins in serum, and HbsAg proteins in serum. The changes in the levels of biomarkers were indicative of strong repression of viral replication and transcription to all cells delivered to in the human chimeric liver mouse. The mice may be further evaluated for effects of multiplexed repression on efficacy and durability, in vivo HBV methylation patterns, or on strength of repression after re-dosing.

A biodistribution mouse cohort (n=12) was harvested after 18 hours post administration to assess delivery efficiency across multiple delivery modalities. Prior to evaluating repression in the main cohort, a sentinel redosing cohort was redosed at either 1 mpk, 2 mpk, or 3 mpk to test tolerability. The mice were also redosed after 21 days or 24 days (approximately at day 102 of the mouse study).

As shown in FIG. 25, approximately 50% repression of HBsAg and HBV DNA was seen with an exemplary gRNA HBVg_22 (SEQ ID NO: 412) five days post administration (Day 86). FIG. 26 shows fold change in the post-dose (day 5) to pre-dose (2 days prior) metric highlighting the levels of repression. These data represent strong evidence that the gRNA combined with the fusion protein induced near complete repression in vivo with native cccDNA.*=p<0.05, **=p<0.01, and ***=p<0.001 with students paired t-test)

A redosing cohort was evaluated after redosing the mice with 2 mpk gRNA after 21 days from the start of the study outlined in FIG. 24. As shown in FIGS. 27A-27D, there was an improvement in repression after redosing with HBVg_22 (SEQ ID NO: 412) either alone or multiplexed with HBVg_185 (SEQ ID NO: 575), or when delivered by an LNP conjugated with GalNAc, in combination with either an mRNA encoding a dSpCas9-KRAB fusion protein (SEQ ID NO:594) (FIGS. 27A-C) or DNMT3A/L-dSpCas9-KRAB (FIG. 27D).

An additional human chimeric FRG mouse study was run with a similar chronic infection phase, followed by a similar ETV dosing phase prior to LNP administration. All LNPs used in this study were conjugated along with 0.15% molecular weight of GalNAc-PEG lipid to improve delivery in this chimeric mouse context. Following a single 2mpk RO injection of LNP containing either HBVg_22 (SEQ ID NO: 412) or a non-targeting gRNA along with an mRNA encoding DNMT3A/3L-dSpCas9-KRAB. Following this single dose, there was durable repression of serum HBeAg and HBsAg protein levels, as well similar reductions in serum HBV DNA levels out to Day 33 post LNP administration when compared to the non-targeting gRNA (FIG. 28A). Single mouse tracks of the degree of repression highlight the consistency of response seen across animals in these serum HBV protein metrics (FIG. 28B). Mice were harvested 72 hrs post LNP administration, tissues were fixed with formalin overnight, and samples were subjected to multi-channel RNAscope to show individual mRNA molecules in the cells (FIG. 28C). In regions with high Cas9 mRNA signal at this timepoint, we are able to see marked reductions in pgRNA signal in HBVg_22 (SEQ ID NO: 412)-delivered mice as compared to mice that received a non-targeting gRNA, with most remaining pgRNA signal being extracellular in the HBVg_22 (SEQ ID NO: 412) groups (FIG. 28A).

Example 8: Identification of Zinc Finger Proteins for Targeted Transcriptional Repression of Genes and Regulatory Elements Thereof Associated with Viral Replication and Transcription

Engineered zinc finger proteins (eZFPs) were designed to bind to genes and regulatory elements of HBV associated with viral replication and transcription. Fusion proteins (eZFP-KRAB fusion proteins) comprising KRAB and one of 122 designed eZFPs were transduced into Hep3B cells to identify eZFPs with the highest transcriptional repression.

The eZFPs were designed as described in Section I-C. The mRNA encoding the fusion proteins was generated and transfected via lipofectamine into Hep3B cells in two batches (FIGS. 29A and 29B). The cells expressing the eZFP-KRAB fusion proteins (3×FLAG-SV40NLS-eZFP-SV40NLS-KRAB fusion proteins) were assessed by qPCR for HBV RNA levels after three days. The mRNA levels were compared to cells transfected with pTT183 (a dCas9-KRAB control) in combination with either HBVg_22 or HBVg_63. Negative controls included a TriLink GFP control, a non-targeting zinc finger protein pZFP0131 that does not bind any unique 18 bp sequence in the human genome, and non-targeting gRNA. Twenty-eight of the eZFP-KRAB fusion proteins screened led to decreased HBV mRNA levels in the Hep3B cells on Day 3 (FIGS. 29A and 29B; see also Table E4). These included the eZFP-KRAB fusion proteins set forth in SEQ ID NOs: 944-971 (Table E5), that targeted the target sites set forth in SEQ ID NOs: 1028-1055.

Example 9: Comparison Between Repression Induced by dSpCas9-KRAB and eZFP-KRAB Fusion Proteins

To compare the level of transcriptional repression induced by the eZFP-KRAB fusion proteins with the dSpCas9-KRAB and gRNA system, Hep3B cells were transfected via lipofectamine with mRNA encoding the most effective eZFP-KRAB fusion proteins set forth in SEQ ID NOs: 961, 962, or 968, and mRNA encoding dSpCas9-KRAB (SEQ ID NO: 595) with either gRNA HBVg_22 (SEQ ID NO:412) or HBVg_63 (SEQ ID NO: 453). Non-targeting (NT) gRNA, GFP, and ZFP-NT (non-targeting eZFP comprising a KRAB domain) were included as negative controls. The cells expressing the eZFP-KRAB fusion or the dSpCas9-KRAB proteins were assessed by qPCR for HBV RNA levels after three days. FIG. 30 shows a preliminary comparison between repression induced by i) HBVg_22 (SEQ ID NO: 412) in combination with dSpCas9-KRAB fusion protein (SEQ ID NO: 595), ii) HBVg_63 (SEQ ID NO: 453) in combination with dSpCas9-KRAB fusion protein (SEQ ID NO: 595), and iii) the most effective eZFP-KRAB fusion proteins set forth in SEQ ID NOs: 961, 962, and 968. As shown in FIG. 30 the ZFP-KRAB fusion proteins induced transcriptional repression that was comparable to the repression mediated by the dSpCas9-KRAB fusion proteins.

FIGS. 31A and 31B depict the targeting positions of each eZFP along the HB X-promoter (HBx) start site. As shown in the FIGS. 31A-31B, the most effective eZFPs (set forth in SEQ ID NOs: 961, 962, and 968) targeted the same general region targeted by the gRNAs HBVg_22 (SEQ ID NO: 412) and HBVg_63 (SEQ ID NO: 453). These data show that significant repression was achieved using either DNA-binding domains. These results demonstrate the robustness of targeting the positions between 1250 base pairs (bp) to 1374 bp, and particularly the region 1260 bp to 1300 bp, of the HBV genome to induce transcriptional repression of HBV.

Example 10: Strong Repression of cccDNA Achieved with the eZFP-KRAB Fusions in the HepG2.NTCP True Infection Model

The 28 eZFP-KRAB fusion proteins identified in Example 8 were screened in the HepG2.NTCP true infection model. HepG2.NTCP cells enable a true infection model of HBV as the HBV infection is sustained due to the generation and presence of native cccDNA.

The mRNA encoding the top 28 fusion proteins was generated and transfected via lipofectamine into the HepG2.NTCP cells in two batches. The cells expressing the eZFP-KRAB fusion proteins were assessed by qPCR for HBV RNA levels 6 days post-lipofection. FIGS. 32A-32B depict the fold change in total HBV RNA mediated by each eZFP-KRAB fusion protein in HepG2.NTCP cells. As shown in FIGS. 32A-32B, several eZFP-KRAB fusion proteins effectively repressed the HBV pregenomic (pgRNA) from the cccDNA by day six. FIG. 33 shows the fold change in total HBV RNA mediated by each eZFP-KRAB fusion protein across the HBx promoter position. The eZFP fusion proteins are color-coded by the percent of conservation across HBV subtypes. As shown in FIG. 33, several eZFP-KRAB fusion proteins targeted a range of sites across the HBx promoter region of the cccDNA and mediated transcriptional repression. Specifically, one of the best eZFP-KRAB repressor proteins (eZFP_18) showed about 91% conservation across the HBV subtypes.

Together, these results demonstrate robust repression of HBV expression by the eZFP-KRAB repressor proteins.

Example 11: Durable HBV Repression Achieved with DNMT3A/L-eZFP-KRAB Fusion Proteins

Fusion proteins comprising DNMT3A/L (SEQ ID NO: 651), KRAB (SEQ ID NO:590), and one of the 12 most efficient eZFPs were designed to identify the DNMT3A/L-eZFP-KRAB fusion proteins with the highest transcriptional repression. The mRNA encoding the fusion proteins was generated and transfected via lipofectamine into Hep3B cells. The cells expressing the DNMT3A/L-eZFP-KRAB fusion proteins (Table E6) containing the eZFP linked to DNMT3A/L (SEQ ID NO:651) and KRAB (SEQ ID NO: 590) were assessed by qPCR for HBV RNA levels after day 4 or day 15. FIG. 34 shows the fold change in total HBV RNA mediated by each DNMT3A/L-eZFP-KRAB fusion protein. As shown in FIG. 34, several of the fusion proteins mediated transcriptional repression on day 4 and day 15. Specifically, the DNMT3A/L-eZFP-KRAB fusion proteins comprising eZFP_18 (SEQ ID NO:1017) and eZFP_19 (SEQ ID NO:1018) mediated the highest transcriptional repression by day 4, which was durable until day 15. The repression levels mediated by these fusion proteins was comparable to the levels mediated by DNMT3A/L-dSpCas9-KRAB (SEQ ID NO: 645) in combination with HBVg_22 (SEQ ID NO: 412).

To assess differentially-expressed genes (DEG) mediated by the DNMT3A/L-eZFP-KRAB fusion proteins, HepG2.NTCP cells were transfected with the mRNA encoding the DNMT3A/L-eZFP-KRAB fusion proteins. The RNA was harvested after 72 hours and RNA-sequencing was performed. FIG. 35 shows changes in differentially expressed genes mediated by the fusion proteins 72 hours post-lipofection. The results show that DNMT3A/L-eZFP-KRAB fusion proteins composed of eZFP_18 (SEQ ID NO:1017) and eZFP_19 (SEQ ID NO:1018) induced minimal off-target differential expression relative to lipid control. Additionally, no significantly altered gene expression was seen following delivery of HBVg_22 (SEQ ID NO: 412) with dSpCas9-KRAB (SEQ ID NO: 594). FIGS. 36A-36B shows changes in differentially-expressed genes mediated by the DNMT3A/L-eZFP-KRAB fusion proteins 72 hours post-lipofection as compared to either GFP (FIG. 36A) or non-targeting (NT) control (FIG. 36B). The DNMT3A/L-eZFP-KRAB fusion proteins composed of eZFP_18 (SEQ ID NO:1017) imparted minimal to no off-target differential expression compared to either GFP only or a non-targeting ZFP-KRABNT fusion control.

Together, these results show durable transcriptional repression of HBV RNA by the DNMT3A/L-eZFP-KRAB repressor fusion proteins composed of eZFP_18 (SEQ ID NO:1017) and eZFP_19 (SEQ ID NO:1018) mediated the highest transcriptional repression with minimal to no off-target gene expression. In general, these data support the therapeutic utility of the eZFPs, including in fusion proteins for targeted repression of HBV expression.
