Abstract
Description
Technical Field
[0001] This application claims the benefit of priority of U.S. Provisional Patent Application No. 62 / 566,240, filed Sep. 29, 2017, the contents of which are hereby incorporated by reference in their entirety.
[0002] Provided herein are lipid nanoparticle (“LNP”) compositions with improved properties for delivering biologically active agents, particularly RNA, mRNA, and guide RNA. The LNP compositions facilitate the delivery of RNA agents across cell membranes and, in certain embodiments, such compositions are used to introduce components and compositions for gene editing into living cells.
Background Art
[0003] Biologically active agents that are particularly difficult to deliver to cells include proteins, nucleic acid-based drugs, and derivatives thereof. Compositions for delivering promising gene editing technologies into cells, such as compositions for delivering CRISPR / Cas9 system components, are of particular interest.
[0004] Currently, there are numerous components and systems for in vivo editing of cellular genes, offering great potential for the treatment of diseases. The CRISPR / Cas gene editing system is active as a ribonucleoprotein complex within cells. The RNA-dependent nuclease binds to DNA sequences within the cell and induces cleavage. This site-specific nuclease activity promotes gene editing through the cell's own natural processes. For example, in response to double-strand DNA breaks (DSBs), cells use an error-prone repair process known as non-homologous end joining ("NHEJ"). During NHEJ, the cell adds or removes nucleotides at the DNA ends, which may result in a sequence that has changed from the cleaved sequence. In other situations, the cell repairs DSBs by mechanisms such as homologous recombination repair ("HDR") or homologous recombination ("HR"), where an endogenous or exogenous template can be used to direct the repair of the cleavage. In some of these editing techniques, cellular mechanisms that repair single-strand breaks (SSBs) or DSBs are utilized.
[0005] Compositions are needed for delivering CRISPR / Cas protein and nucleic acid components to cells, such as the cells of a patient. In particular, compositions for delivering mRNA encoding the CRISPR protein component, and compositions for delivering CRISPR guide RNA are of particular interest. Compositions having properties useful for delivery in vitro and in vivo, which can stabilize and deliver the RNA components, are also of particular interest. SUMMARY OF THE INVENTION

Mode for Carrying Out the Invention
[0012] The present disclosure provides embodiments of lipid nanoparticle (LNP) compositions of RNAs, such as CRISPR / Cas component RNAs (''cargo'') for delivery to cells, and methods of using them. The LNP compositions may exhibit improved properties compared to conventional delivery techniques. The LNP compositions may contain an RNA component and a lipid component as defined herein. In certain embodiments, the RNA component includes a Cas nuclease, such as a class 2 Cas nuclease. In certain embodiments, the cargo or RNA component includes an mRNA encoding a class 2 Cas nuclease, and a guide RNA or a nucleic acid encoding a guide RNA. Also provided are gene editing methods and methods of making engineered cells.
[0013] CRISPR / Cas Cargo The CRISPR / Cas cargo delivered via the LNP formulation may include an mRNA molecule encoding a target protein. For example, it includes an mRNA for expressing a protein such as green fluorescent protein (GFP) and an RNA-induced DNA binding factor, or a Cas nuclease. Provided are LNP compositions containing a Cas nuclease mRNA that enables intracellular expression of the Cas9 protein, such as a class 2 Cas nuclease mRNA. Further, the cargo may contain one or more guide RNAs or nucleic acids encoding guide RNAs. For example, a template nucleic acid for repair or recombination may also be included in the composition, or the template nucleic acid may be used in the methods described herein.
[0014] "mRNA" refers to a polynucleotide containing an open reading frame that can be translated into a polypeptide (i.e., can be used as a substrate for translation by ribosomes and aminoacylated tRNAs). mRNA can include a ribose residue or an analog thereof, such as a 2'-methoxyribose residue, etc., and a phosphate-sugar backbone. In some embodiments, the sugar of the mRNA phosphate-sugar backbone consists essentially of ribose residues, 2'-methoxyribose residues, or a combination thereof. Generally, mRNA does not contain a substantial amount of thymidine residues (e.g., the thymidine residue is 0 or less than 30, 20, 10, 5, 4, 3, or 2, or the thymidine content is less than 10%, 9%, 8%, 7%, 6%, 5%, 4%, 4%, 3%, 2%, 1%, 0.5%, 0.2%, or 0.1%). mRNA can contain modified uridine at some or all of its uridine positions.
[0015] CRISPR / Cas nuclease system One of the components of the disclosed formulation is mRNA encoding an RNA-induced DNA-binding factor, such as a Cas nuclease.
[0016] As used herein, "RNA-guided DNA binding factor" means a polypeptide or complex of polypeptides having RNA and DNA binding activities, or a DNA binding subunit of such a complex, where the DNA binding activity is sequence specific and dependent on the sequence of the RNA. Exemplary RNA-guided DNA binding factors include Cas base / nickase and its inactive form ("dCas DNA binder"). As used herein, "Cas nuclease" includes Cas base, Cas nickase, and dCas DNA binder. Cas base / nickase and dCas DNA binder include the Csm complex or Cmr complex of the type III CRISPR system, Cas10, Csm1, or Cmr2 of its subunits, the Cascade complex of the type I CRISPR system, Cas3 of its subunits, and class 2 Cas nuclease. As used herein, "class 2 Cas nuclease" is a single-stranded polypeptide having RNA-guided DNA binding activity. Class 2 Cas nucleases further include class 2 Cas base / nickase (e.g., mutants such as H840A, D10A, or N863A) having RNA-guided DNA cleavage activity or nickase activity, and class 2 dCas DNA binder inactivated for cleavage / nickase activity. Examples of class 2 Cas nucleases include proteins such as Cas9, Cpf1, C2c1, C2c2, C2c3, HF Cas9 (e.g., mutants such as N497A, R661A, Q695A, Q926A), HypaCas9 protein (e.g., mutants such as N692A, M694A, Q695A, H698A), eSPCas9(1.0) protein (e.g., mutants such as K810A, K1003A, R1060A), and eSPCas9(1.1) protein (e.g., mutants such as K848A, K1003A, R1060A), and variants thereof. The Cpf1 protein (Zetsche et al., Cell, 163:1-13 (2015)) is homologous to Cas9 and contains an RuvC-like nuclease domain. The Cpf1 sequence of Zetsche is incorporated herein by reference in its entirety.For example, refer to Table S1 and Table S3 of Zetsche. For example, refer to Makarova et al., Nat Rev Microbiol, 13(11):722-36(2015), Shmakov et al., Molecular Cell, 60:385-397(2015).
[0017] In some embodiments, the RNA-guided DNA binding factor is a class 2 Cas nuclease. In some embodiments, the RNA-guided DNA binding factor has cleavage activity, which may also be referred to as double-stranded endonuclease activity. In some embodiments, the RNA-guided DNA binding factor comprises a Cas nuclease such as a class 2 Cas nuclease (which may be, for example, a type II, V, or VI Cas nuclease). Examples of class 2 Cas nucleases include, for example, Cas9, Cpf1, C2c1, C2c2, and C2c3 proteins and variants thereof. Examples of Cas9 nucleases include those of the type II CRISPR systems of S. pyogenes, S. aureus, and other prokaryotes (see, for example, the list in the next paragraph), as well as modified forms thereof (e.g., engineered or mutants). For example, refer to U.S. 2016 / 0312198 A1, U.S. 2016 / 0312199 A1. Other examples of Cas nucleases include Cas10, Csm1, or Cmr2 of the Csm complex or Cmr complex of the type III CRISPR system or subunits thereof, and the Cascade complex of the type I CRISPR system, or Cas3 of subunits thereof. In some embodiments, the Cas nuclease may be of a type IIA, IIB, or IIC system. For discussion of various CRISPR systems and Cas nucleases, see, for example, Makarova et al., Nat.Rev.Microbiol. 9:467-477(2011), Makarova et al., Nat.Rev.Microbiol, 13:722-36(2015), Shmakov et al., Molecular Cell, 60:385-397(2015).

[0019] In some embodiments, the Cas nuclease is a Cas9 nuclease from Streptococcus pyogenes. In some embodiments, the Cas nuclease is a Cas9 nuclease from Streptococcus thermophilus. In some embodiments, the Cas nuclease is a Cas9 nuclease from Neisseria meningitidis. In some embodiments, the Cas nuclease is a Cas9 nuclease from Staphylococcus aureus. In some embodiments, the Cas nuclease is a Cpf1 nuclease from Francisella novicida. In some embodiments, the Cas nuclease is a Cpf1 nuclease from Acidaminococcus sp.

In certain embodiments, the Cas nuclease is a Cpf1 nuclease derived from Acidaminococcus or Lachnospiraceae.
[0020] Wild-type Cas9 has two nuclease domains, RuvC and HNH. The RuvC domain cleaves the non-target DNA strand, and the HNH domain cleaves the target DNA strand. In some embodiments, the Cas9 nuclease comprises two or more RuvC domains and / or two or more HNH domains. In some embodiments, the Cas9 nuclease is wild-type Cas9. In some embodiments, Cas9 can induce double-strand breaks in target DNA. In certain embodiments, the Cas nuclease may cleave dsDNA, cleave one strand of dsDNA, or have neither cleavage activity nor nickase activity on DNA. An exemplary Cas9 amino acid sequence is set forth as SEQ ID NO: 3. An exemplary Cas9 mRNA ORF sequence, including the start codon and stop codon, is set forth as SEQ ID NO: 4. An exemplary Cas9 mRNA coding sequence suitable for inclusion in a fusion protein is set forth as SEQ ID NO: 10.
[0021] In some embodiments, a chimeric Cas nuclease is used, in which case one domain or region of such a protein is replaced with a portion of a different protein. In some embodiments, the Cas nuclease domain may be replaced with a domain derived from a different nuclease, such as Fok1. In some embodiments, the Cas nuclease may be a modified nuclease.
[0022] In other embodiments, the Cas nuclease may be derived from a type I CRISPR / Cas system. In some embodiments, the Cas nuclease may be a component of the Cascade complex of the type I CRISPR / Cas system. In some embodiments, the Cas nuclease may be the Cas3 protein. In some embodiments, the Cas nuclease may be derived from a type III CRISPR / Cas system. In some embodiments, the Cas nuclease may have RNA cleavage activity.
[0023] In some embodiments, the RNA-guided DNA binding factor has single-strand nickase activity, i.e., it can cleave a single DNA strand to create a single-strand break, also known as a "nick". In some embodiments, the RNA-guided DNA binding factor comprises a Cas nickase. A nickase is an enzyme that nicks dsDNA, i.e., cleaves one strand of the DNA double helix but not the other. In some embodiments, the Cas nickase is a variant of a Cas nuclease (e.g., the Cas nucleases described above), e.g., the endonuclease cleavage active site is inactivated by one or more changes (e.g., point mutations) within the catalytic domain. For discussion of Cas nickases and exemplary catalytic domain modifications, see, e.g., U.S. Patent No. 8,889,356. In some embodiments, a Cas nickase, such as Cas9 nickase, has an inactivated RuvC domain or HNH domain. An exemplary amino acid sequence of a Cas9 nickase is set forth as SEQ ID NO: 6. The ORF sequence of an exemplary Cas9 nickase mRNA including the start codon and stop codon is set forth as SEQ ID NO: 7. The coding sequence of an exemplary Cas9 nickase mRNA suitable for inclusion in a fusion protein is set forth as SEQ ID NO: 11.
[0024] In some embodiments, the RNA-guided DNA binding factor is modified to contain only one functional nuclease domain. For example, the protein of the factor may be modified to mutate or completely or partially delete one of the nuclease domains to reduce its nucleic acid cleavage activity. In some embodiments, a nickase having a reduced-activity RuvC domain is used. In some embodiments, a nickase having an inactivated RuvC domain is used. In some embodiments, a nickase having a reduced-activity HNH domain is used. In some embodiments, a nickase having an inactivated HNH domain is used.
[0025] In some embodiments, conserved amino acids within the Cas protein nuclease domain are substituted to reduce or alter nuclease activity. In some embodiments, the Cas nuclease may include an amino acid substitution in the RuvC or RuvC-like nuclease domain. Exemplary amino acid substitutions in the RuvC or RuvC-like nuclease domain include D10A (based on the S. pyogenes Cas9 protein). See, e.g., Zetsche et al. (2015) Cell Oct 22:163(3):759-771. In some embodiments, the Cas nuclease may include an amino acid substitution in the HNH or HNH-like nuclease domain. Exemplary amino acid substitutions in the HNH or HNH-like nuclease domain include E762A, H840A, N863A, H983A, and D986A (based on the S. pyogenes Cas9 protein). See, e.g., Zetsche et al. (2015). Further exemplary amino acid substitutions include D917A, E1006A, and D1255A (based on the Francisella novicida U112 Cpf1 (FnCpf1) sequence (UniProtKB-A0Q7Q2(CPF1_FRATN))).
[0026] In some embodiments, the mRNA encoding the nickase is provided in combination with a pair of guide RNAs that are complementary to each of the sense and antisense strands of the target sequence. In this embodiment, the guide RNAs direct the nickase to the target sequence and introduce a DSB by creating a nick in the opposite strand of the target sequence (i.e., double nicking). In some embodiments, the use of double nicking can improve specificity and reduce off-target effects. In some embodiments, the nickase is used with two separate guide RNAs that target opposing DNA strands to create a double nick in the target DNA. In some embodiments, the nickase is used with two separate guide RNAs that are selected to be proximal to create a double nick in the target DNA.
[0027] In some embodiments, the RNA-guided DNA binding factor has no cleavage activity and no nickase activity. In some embodiments, the RNA-guided DNA binding factor comprises a dCas DNA binding polypeptide. The dCas polypeptide has DNA binding activity but essentially no catalytic (cleavage / nickase) activity. In some embodiments, the dCas polypeptide is a dCas9 polypeptide. In some embodiments, the RNA-guided DNA binding factor or the dCas DNA binding polypeptide having no cleavage activity and no nickase activity is a variant of a Cas nuclease (e.g., the Cas nuclease described above), e.g., the endonuclease cleavage active site thereof is inactivated by one or more changes (e.g., point mutations) within its catalytic domain. See, e.g., U.S. 2014 / 0186958 A1, U.S. 2015 / 0166980 A1. An exemplary dCas9 amino acid sequence is set forth as SEQ ID NO: 8. An exemplary Cas9 mRNA ORF sequence including the start codon and the stop codon is set forth as SEQ ID NO: 9. An exemplary Cas9 mRNA coding sequence suitable for inclusion in a fusion protein is set forth as SEQ ID NO: 12.
[0028] In some embodiments, the RNA-guided DNA binding factor comprises one or more heterologous functional domains (e.g., is or comprises a fusion polypeptide).
[0029] In some embodiments, the heterologous functional domain may facilitate the transport of the RNA-guided DNA binding factor into the nucleus of the cell. For example, the heterologous functional domain may be a nuclear localization signal (NLS). In some embodiments, the RNA-guided DNA binding factor may be fused with 1 to 10 NLSs (plural possible). In some embodiments, the RNA-guided DNA binding factor may be fused with 1 to 5 NLSs (plural possible). In some embodiments, the RNA-guided DNA binding factor may be fused with one NLS. When using one NLS, such NLS may be ligated at the N-terminus or C-terminus of the RNA-guided DNA binding factor sequence. Such one NLS may also be inserted inside the RNA-guided DNA binding factor sequence. In other embodiments, the RNA-guided DNA binding factor may be fused with two or more NLSs. In some embodiments, the RNA-guided DNA binding factor may be fused with 2, 3, 4, or 5 NLSs. In some embodiments, the RNA-guided DNA binding factor may be fused with two NLSs. In certain situations, the two NLSs may be the same (e.g., two SV40 NLSs) or different. In some embodiments, the RNA-guided DNA binding factor is ligated and fused at the carboxy terminus with two SV40 NLS sequences. In some embodiments, the RNA-guided DNA binding factor may be fused with two NLSs, wherein one is ligated at the N-terminus and one is ligated at the C-terminus. In some embodiments, the RNA-guided DNA binding factor may be fused with three NLSs. In some embodiments, the RNA-guided DNA binding factor may not need to be fused with an NLS. In some embodiments, the NLS may be a monopartite sequence such as PKKKRKV or PKKKRRV of, for example, the SV40 NLS. In some embodiments, the NLS may be a bipartite sequence such as KRPAATKKAGQAKKKK of the NLS of nucleoplasmin. In certain embodiments, a single PKKKRKV NLS may be ligated at the C-terminus of the RNA-guided DNA binding factor. Optionally, one or more linkers are included at the fusion site.
[0030] In some embodiments, the heterologous functional domain may be capable of modifying the intracellular half-life of the RNA-guided DNA binding factor. In some embodiments, it may be capable of extending the half-life of the RNA-guided DNA binding factor. In some embodiments, the half-life of the RNA-guided DNA binding factor may be shortened. In some embodiments, the heterologous functional domain may be capable of increasing the stability of the RNA-guided DNA binding factor. In some embodiments, the heterologous functional domain may be capable of decreasing the stability of the RNA-guided DNA binding factor. In some embodiments, the heterologous functional domain may act as a proteolytic signal peptide. In some embodiments, proteolysis may be mediated by a proteolytic enzyme such as, for example, a proteasome, a lysosomal protease, or a calpain protease. In some embodiments, the heterologous functional domain may comprise a PEST sequence. In some embodiments, the RNA-guided DNA binding factor may be modified by the addition of ubiquitin or a polyubiquitin chain. In some embodiments, the ubiquitin may be a ubiquitin-like protein (UBL). Non-limiting examples of ubiquitin-like proteins include small ubiquitin-like modifier (SUMO), ubiquitin cross-reactive protein (UCRP; also known as interferon-inducible gene 15 (ISG15)), ubiquitin-related modifier 1 (URM1), neural precursor cell expressed, developmentally down-regulated 8 (NEDD8; also called Rub1 in S. cerevisiae), human leukocyte antigen F-related (FAT10), autophagy 8 (ATG8) and autophagy 12 (ATG12), Fau ubiquitin-like protein (FUB1), membrane-anchored UBL (MUB), ubiquitin-fold modifier 1 (UFM1), and ubiquitin-like protein 5 (UBL5).
[0031] In some embodiments, the heterologous functional domain may be a marker domain. Non-limiting examples of marker domains include fluorescent proteins, purification tags, epitope tags, and reporter gene sequences. In some embodiments, the marker domain may be a fluorescent protein. Non-limiting examples of suitable fluorescent proteins include green fluorescent protein (e.g., GFP, GFP-2, tagGFP, turboGFP, sfGFP, EGFP, Emerald, Azami Green, monomeric Azami Green, CopGFP, AceGFP, ZsGreen1), yellow fluorescent protein (e.g., YFP, EYFP, Citrine, Venus, YPet, PhiYFP, ZsYellow1), blue fluorescent protein (e.g., EBFP, EBFP2, Azurite, mKalamal, GFPuv, Sapphire, T-sapphire), cyan fluorescent protein (e.g., ECFP, Cerulean, CyPet, AmCyan1, Midoriishi-Cyan), red fluorescent protein (e.g., mKate, mKate2, mPlum, DsRed monomer, mCherry, mRFP1, DsRed-Express, DsRed2, DsRed-Monomer, HcRed-Tandem, HcRed1, AsRed2, eqFP611, mRasberry, mStrawberry, Jred), and orange fluorescent protein (mOrange, mKO, Kusabira-Orange, monomeric Kusabira-Orange, mTangerine, tdTomato) or any other suitable fluorescent protein. In other embodiments, the marker domain may be a purification tag and / or an epitope tag.Non-limiting exemplary tags include glutathione-S-transferase (GST), chitin binding protein (CBP), maltose binding protein (MBP), thioredoxin (TRX), poly(NANP), tandem affinity purification (TAP) tag, myc, AcV5, AU1, AU5, E, ECS, E2, FLAG, HA, nus, Softag 1, Softag 3, Strep, SBP, Glu-Glu, HSV, KT3, S, S1, T7, V5, VSV-G, 6xHis, 8xHis, biotin carboxyl carrier protein (BCCP), poly-His, and calmodulin. Non-limiting exemplary reporter genes include glutathione-S-transferase (GST), horseradish peroxidase (HRP), chloramphenicol acetyltransferase (CAT), beta-galactosidase, beta-glucuronidase, luciferase, or a fluorescent protein.
[0032] In further embodiments, the heterologous functional domain may direct an RNA-inducible DNA binding factor to a particular subcellular organelle, cell type, tissue, or organ. In some embodiments, the heterologous functional domain may direct an RNA-inducible DNA binding factor to mitochondria.
[0033] In further embodiments, the heterologous functional domain may be an effector domain. When orienting an RNA-guided DNA binding factor to its target sequence, for example, when orienting a Cas nuclease to a target sequence by a gRNA, the effector domain may modify or affect the target sequence. In some embodiments, the effector domain may be selected from a nucleic acid binding domain, a nuclease domain (e.g., a non-Cas nuclease domain), an epigenetic modification domain, a transcriptional activation domain, or a transcriptional repressor domain. In some embodiments, the heterologous functional domain is a nuclease such as FokI nuclease. See, for example, U.S. Patent No. 9,023,649. In some embodiments, the heterologous functional domain is a transcriptional activator or a transcriptional repressor. See, for example, Qi et al., “Repurposing CRISPR as an RNA-guided platform for sequence-specific control of gene expression,” Cell 152:1173-83 (2013), Perez-Pinera et al., “RNA-guided gene activation by CRISPR-Cas9-based transcription factors,” Nat. Methods 10:973-6 (2013), Mali et al., ”CAS9 transcriptional activators for target specificity screening and paired nickases for cooperative genome engineering,” Nat. Biotechnol. 31:833-8 (2013), Gilbert et al., “CRISPR-mediated modular RNA-guided regulation of transcription in eukaryotes,” Cell 154:442-51 (2013). Thus, the RNA-guided DNA binding factor essentially becomes a transcription factor that can be oriented to bind to a desired target sequence using a guide RNA.In certain embodiments, the DNA modification domain is a methylation domain such as a demethylation domain or a methyltransferase domain. In certain embodiments, the effector domain is a DNA modification domain such as a base editing domain. In certain embodiments, the DNA modification domain is a nucleic acid editing domain that introduces a specific modification into DNA, such as a deaminase domain. See, e.g., WO2015 / 089406, U.S.2016 / 0304846. The nucleic acid editing domains, deaminase domains, and Cas9 variants described in WO2015 / 089406 and U.S.2016 / 0304846 are incorporated herein by reference.
[0034] The nuclease may comprise at least one domain that interacts with a guide RNA (“gRNA”). Further, the nuclease may be oriented to a target sequence by the gRNA. In class 2 Cas nuclease systems, the gRNA interacts with the nuclease and the target sequence, thereby leading to binding to the target sequence. In some embodiments, the gRNA provides specificity for the targeted cleavage, while the nuclease may be promiscuous and pair with different gRNAs to cleave different target sequences. Class 2 Cas nucleases may pair with the gRNA scaffold structures of the types, orthologs, and exemplary species listed above.
[0035] Guide RNA (gRNA) In some embodiments of the present disclosure, the cargo of the LNP formulation includes at least one gRNA. The gRNA may direct a Cas nuclease or a class 2 Cas nuclease to a target sequence on a target nucleic acid molecule. In some embodiments, the gRNA binds to a class 2 Cas nuclease to provide specificity for cleavage by the class 2 Cas nuclease. In some embodiments, the gRNA and the Cas nuclease may form a ribonucleoprotein (RNP) that can be delivered by the LNP composition, such as a CRISPR / Cas complex such as a CRISPR / Cas9 complex. In some embodiments, the CRISPR / Cas complex may be a type II CRISPR / Cas9 complex. In some embodiments, the CRISPR / Cas complex may be a type V CRISPR / Cas complex such as a Cpf1 / guide RNA complex. The Cas nuclease and a specific gRNA may be paired. The gRNA scaffold structure that pairs with each class 2 Cas nuclease varies depending on the individual CRISPR / Cas system.
[0036] "Guide RNA", "gRNA", and simply "guide" are used interchangeably herein and refer to either a crRNA (also known as CRISPR RNA) or a combination of a crRNA and a trRNA (also known as tracrRNA). The crRNA and the trRNA may be associated as a single RNA molecule (single guide RNA, sgRNA) or as two separate RNA molecules (dual guide RNA, dgRNA). "Guide RNA" or "gRNA" refers to each type. The trRNA may be a naturally occurring sequence or a trRNA sequence having modifications or variations compared to a naturally occurring sequence.
[0037] As used herein, a "guide sequence" is a sequence within a guide RNA that is complementary to a target sequence and functions to direct the guide RNA to the target sequence for binding or modification (e.g., cleavage) by an RNA-guided DNA binding factor. A "guide sequence" may also be referred to as a "directing sequence" or "spacer sequence". For example, in the case of Streptococcus pyogenes (i.e., Spy Cas9) and related Cas9 homologs / orthologs, the guide sequence can be 20 base pairs in length. Shorter or longer sequences, such as sequences 15, 16, 17, 18, 19, 21, 22, 23, 24, or 25 nucleotides in length, can be used as guides. In some embodiments, the target sequence is, for example, within a gene or on a chromosome and is complementary to the guide sequence. In some embodiments, the degree of complementarity or identity between the guide sequence and its corresponding target sequence can be about 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100%. In some embodiments, the guide sequence and the target region may be 100% complementary or identical. In other embodiments, the guide sequence and the target region may contain at least one mismatch. For example, the guide sequence and the target sequence may contain 1, 2, 3, or 4 mismatches, in which case the full length of the target sequence is at least 17, 18, 19, 20, or more base pairs. In some embodiments, the guide sequence and the target region may contain 1 to 4 mismatches, in which case the guide sequence contains at least 17, 18, 19, 20, or more nucleotides. In some embodiments, the guide sequence and the target region may contain 1, 2, 3, or 4 mismatches, in which case the guide sequence contains 20 nucleotides.
[0038] Since the nucleic acid serving as a substrate for the Cas protein is double-stranded nucleic acid, the target sequences of the Cas protein include both the plus strand and the minus strand of genomic DNA (i.e., a given sequence and the reverse complementary strand of such a sequence). Therefore, when it is said that a guide sequence is "complementary to the target sequence", it should be understood that such a guide sequence can direct the guide RNA to bind to the reverse complementary strand of the target sequence. Thus, in some embodiments, when the guide sequence binds to the reverse complementary strand of the target sequence, such a guide sequence is identical to a specific nucleotide of the target sequence (e.g., a target sequence without PAM) except that T of the guide sequence is replaced by U.
[0039] The length of the targeting sequence may vary depending on the CRISPR / Cas system and components used. For example, different class 2 Cas nucleases derived from different bacterial species have different optimal targeting sequence lengths. Therefore, the targeting sequence may include 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 35, 40, 45, 50, or more than 50 nucleotides in length. In some embodiments, the targeting sequence length may be 0, 1, 2, 3, 4, or 5 nucleotides longer or shorter than the guide sequence of a naturally occurring CRISPR / Cas system. In certain embodiments, the Cas nuclease and the gRNA scaffold are derived from the same CRISPR / Cas system. In some embodiments, the targeting sequence may include or consist of 18 to 24 nucleotides. In some embodiments, the targeting sequence may include or consist of 19 to 21 nucleotides. In some embodiments, the targeting sequence may include or consist of 20 nucleotides.
[0040] In some embodiments, the sgRNA is a "Cas9 sgRNA" that can mediate RNA-guided DNA cleavage by the Cas9 protein. In some embodiments, the sgRNA is a "Cpf1 sgRNA" that can mediate RNA-guided DNA cleavage by the Cpf1 protein. In certain embodiments, the gRNA comprises a crRNA and a tracrRNA sufficient to form an active complex with the Cas9 protein and mediate RNA-guided DNA cleavage. In certain embodiments, the gRNA comprises a crRNA sufficient to form an active complex with the Cpf1 protein and mediate RNA-guided DNA cleavage. See Zetsche 2015.
[0041] Certain embodiments of the invention also provide nucleic acids encoding the gRNAs described herein, such as expression cassettes. "Guide RNA nucleic acid" is a nucleic acid encoding one or more guide RNAs, used herein to refer to guide RNAs (e.g., sgRNA or dgRNA) and guide RNA expression cassettes.
[0042] In some embodiments, the nucleic acid may be a DNA molecule. In some embodiments, the nucleic acid may comprise a nucleotide sequence encoding a crRNA. In some embodiments, the nucleotide sequence encoding the crRNA comprises a targeting sequence flanked by all or a portion of a repeat sequence derived from a naturally-occurring CRISPR / Cas system. In some embodiments, the nucleic acid may comprise a nucleotide sequence encoding a tracrRNA. In some embodiments, the crRNA and tracrRNA may be encoded by two separate nucleic acids. In other embodiments, the crRNA and tracrRNA may be encoded by a single nucleic acid. In some embodiments, the crRNA and tracrRNA may be encoded by opposite strands of a single nucleic acid. In other embodiments, the crRNA and tracrRNA may be encoded by the same strand of a single nucleic acid. In some embodiments, the gRNA nucleic acid encodes an sgRNA. In some embodiments, the gRNA nucleic acid encodes a Cas9 nuclease sgRNA. In some embodiments, the gRNA nucleic acid encodes a Cpf1 nuclease sgRNA.
[0043] The nucleotide sequence encoding the guide RNA may be operably linked to at least one transcriptional or regulatory control sequence, such as a promoter, 3’UTR, or 5’UTR, for example. In one example, the promoter is a tRNA promoter, such as tRNA Lys3or may be a tRNA chimera. See Mefferd et al., RNA. 2015 21:1683-9, Scherer et al., Nucleic Acids Res. 2007 35:2620-2628. In certain embodiments, the promoter may be recognized by RNA polymerase III (Pol III). Non-limiting examples of Pol III promoters also include the U6 promoter and the H1 promoter. In some embodiments, the nucleotide sequence encoding the guide RNA may be operably linked to a mouse or human U6 promoter. In some embodiments, the gRNA nucleic acid is a modified nucleic acid. In certain embodiments, the gRNA nucleic acid contains modified nucleosides or nucleotides. In some embodiments, the gRNA nucleic acid contains 5' end modifications, such as modified nucleosides or nucleotides that stabilize the nucleic acid and prevent integration of the nucleic acid. In some embodiments, the gRNA nucleic acid contains double-stranded DNA with 5' end modifications on each strand. In certain embodiments, the gRNA nucleic acid contains inverted dideoxy-T or inverted abasic nucleosides or nucleotides as 5' end modifications. In some embodiments, the gRNA nucleic acid contains labels such as biotin, desthiobiotin-TEG, digoxigenin, and fluorescent markers such as FAM, ROX, TAMRA, and Alexa Fluor.
[0044] In certain embodiments, two or more gRNA nucleic acids, such as gRNAs, can be used with the CRISPR / Cas nuclease system. Each gRNA nucleic acid may contain a different targeting sequence such that two or more target sequences are cleaved by the CRISPR / Cas system. In some embodiments, one or more gRNAs may have the same or different properties, such as activity or stability, within the CRISPR / Cas complex. When using two or more gRNAs, each gRNA can be encoded either on the same gRNA nucleic acid or on different gRNA nucleic acids. The promoters used to induce the expression of two or more gRNAs may be the same or different.
[0045] Modified RNA In certain embodiments, the LNP composition comprises modified RNA.
[0046] Modified nucleosides or nucleotides can be present in RNA, such as, for example, gRNA or mRNA. For example, a gRNA or mRNA comprising one or more modified nucleosides or nucleotides is referred to as “modified” RNA and represents the use of non-naturally occurring components or configurations and / or the presence of one or more naturally occurring components or configurations in place of or in addition to the standard residues A, G, C, and U. In some embodiments, the modified RNA is synthesized using non-standard nucleosides or nucleotides referred to herein as “modifications”.
[0047] Modified nucleosides and modified nucleotides include (i) one or both of the unlinked oxygens of the phosphate group and / or one or more changes in the linked oxygens of the phosphate group in the phosphodiester backbone linkage, e.g., substitution (exemplary backbone modifications), (ii) changes in the components of the ribose sugar, e.g., changes such as the hydroxyl at the 2'-position of the ribose sugar, e.g., substitution (exemplary sugar modifications), (iii) substantial substitution of the phosphate moiety with a "dephospho" linker (exemplary backbone modifications), (iv) modification or substitution of the naturally occurring nucleobases, e.g., using non-standard nucleobases (exemplary base modifications), (v) substitution or modification of the ribose-phosphate backbone (exemplary backbone modifications), (vi) modification of the 3'- or 5'-terminus of the oligonucleotide, e.g., removing, modifying or substituting the terminal phosphate group, or modifying by attaching a moiety, cap or linker (such 3'- or 5'-cap modifications may include sugar modifications and / or backbone modifications), and (vii) one or more of sugar modifications or substitutions (exemplary sugar modifications). Certain embodiments include 5'-terminal modifications to mRNA, gRNA, or nucleic acids. Certain embodiments include 3'-terminal modifications to mRNA, gRNA, or nucleic acids. Modified RNA may contain 5'- and 3'-terminal modifications. Modified RNA may contain one or more modified residues at non-terminal positions. In certain embodiments, the gRNA contains at least one modified residue. In certain embodiments, the mRNA contains at least one modified residue.
[0048] As used herein, when an alignment of a first array and a second array shows that the first array matches at least X% of the positions of the entire second array, the first array is considered to "include an array having at least X% identity to the second array". For example, the array AAGA includes an array having 100% identity to the array AAG, because this is considered to show an identity of 100% with matches seen for all three positions of the second array upon alignment. As long as the relevant nucleotides (such as thymidine, uridine, or modified uridine) have the same complement (e.g., for any of thymidine, uridine, or modified uridine, it is adenosine, and in another example, both cytosine and 5-methylcytosine have guanosine or modified guanosine as their complement), the differences between RNA and DNA (generally, the exchange of uridine for thymidine, or vice versa) and the presence of nucleoside analogs such as modified uridine do not contribute to differences in identity or complementarity between polynucleotides. Thus, for example, the sequence 5'-AXG where X is any modified uridine, such as pseudouridine, N1-methylpseudouridine, or 5-methoxyuridine, etc., is considered 100% identical to AUG, and both sequences are completely complementary to the same sequence (5'-CAU). Exemplary alignment algorithms are the Smith-Waterman and Needleman-Wunsch algorithms, which are well-known in the art. Those skilled in the art understand which algorithm and parameter settings are appropriate for a given pair of sequences to be aligned, but generally for sequences of similar length and with expected amino acid identity over 50% or nucleotide identity over 75%, it is generally appropriate to use the Needleman-Wunsch algorithm with the default settings of the Needleman-Wunsch algorithm interface provided by EBI at the www.ebi.ac.uk web server.
[0049] mRNA In some embodiments, the compositions or formulations disclosed herein comprise mRNA comprising an open reading frame (ORF) encoding a Cas nuclease as described herein, or an RNA-guided DNA binding factor such as a Class 2 Cas nuclease. In some embodiments, an mRNA comprising an ORF encoding a Cas nuclease or an RNA-guided DNA binding factor such as a Class 2 Cas nuclease is provided, used, or administered. In some embodiments, the ORF encoding the RNA-guided DNA binding factor is a "modified RNA-guided DNA binding factor ORF" or simply a "modified ORF", which is used as a shorthand to indicate that the ORF is modified in one or more of the following ways: (1) the modified ORF has a uridine content in the range from its minimum uridine content to 150% of such minimum uridine content; (2) the modified ORF has a uridine dinucleotide content in the range from its minimum uridine dinucleotide content to 150% of such minimum uridine dinucleotide content; (3) the modified ORF has at least 90% identity to any one of SEQ ID NOs: 1, 4, 7, 9, 10, 11, 12, 14, 15, 17, 18, 20, 21, 23, 24, 26, 27, 29, 30, 50, 52, 54, 65, or 66; (4) at least 75% of the codons of the modified ORF are the minimum uridine codon(s) for a given amino acid, e.g., the codon(s) with the least uridine (the minimum uridine codon is usually 0 or 1, except for the codon of phenylalanine having 2 uridines), consisting of a set of codons, or (5) the modified ORF contains at least one modified uridine. In some embodiments, the modified ORF is modified in at least two, three, or four of the above-described ways. In some embodiments, the modified ORF contains at least one modified uridine and is modified in at least one, two, three, or all of the ways of (1)-(4) above.
[0050] As used herein, "modified uridine" is used to refer to nucleosides other than thymidine, where the hydrogen bond acceptor is the same as that of uridine and there is one or more structural differences from uridine. In some embodiments, the modified uridine is a substituted uridine, i.e., a uridine in which one or more non-proton substituents (e.g., alkoxy such as methoxy) replace the proton. In some embodiments, the modified uridine is pseudouridine. In some embodiments, the modified uridine is a substituted pseudouridine, i.e., a pseudouridine in which one or more non-proton substituents (e.g., alkyl such as methyl) replace the proton. In some embodiments, the modified uridine is either a substituted uridine, pseudouridine, or a substituted pseudouridine.
[0051] As used herein, "uridine position" refers to the position occupied by uridine or modified uridine in a polynucleotide. Thus, for example, a polynucleotide in which "100% of the uridine positions are modified uridine" contains modified uridine at every position that would be uridine in a conventional RNA of the same sequence (in this case, the bases are all standard bases A, U, C, or G). Unless otherwise specified, U in the polynucleotide sequences disclosed herein or in the sequence table or sequence listing attached to the present disclosure can be either uridine or modified uridine. [Table 1]

In any of the above embodiments, the modified ORF may include a sequence having at least 90%, 95%, 98%, 99%, or 100% identity to any one of SEQ ID NO: 1, 4, 7, 9, 10, 11, 12, 14, 15, 17, 18, 20, 21, 23, 24, 26, 27, 29, 30, 50, 52, 54, 65, or 66.
[0053] In any of the above embodiments, the modified ORF may include a sequence having at least 90%, 95%, 98%, 99%, or 100% identity to any one of SEQ ID NO: 1, 4, 7, 9, 10, 11, 12, 14, 15, 17, 18, 20, 21, 23, 24, 26, 27, 29, 30, 50, 52, 54, 65, or 66.
[0054] In any of the above embodiments, the modified ORF may have a uridine content in the range from its minimum uridine content to 150%, 145%, 140%, 135%, 130%, 125%, 120%, 115%, 110%, 105%, 104%, 103%, 102%, or 101% of such minimum uridine content.
[0055] In any of the above embodiments, the modified ORF may have a uridine dinucleotide content in the range from its minimum uridine dinucleotide content to 150%, 145%, 140%, 135%, 130%, 125%, 120%, 115%, 110%, 105%, 104%, 103%, 102%, or 101% of such minimum uridine dinucleotide content.
[0056] In any of the above embodiments, the modified ORF may contain modified uridines at at least one, a plurality, or all of the uridine positions. In some embodiments, the modified uridine is a uridine modified at the 5-position, for example, with a halogen, methyl, or ethyl. In some embodiments, the modified uridine is a pseudouridine modified at the 1-position, for example, with a halogen, methyl, or ethyl. The modified uridine can be, for example, pseudouridine, N1-methyl-pseudouridine, 5-methoxyuridine, 5-iodouridine, or a combination thereof. In some embodiments, the modified uridine is 5-methoxyuridine. In some embodiments, the modified uridine is 5-iodouridine. In some embodiments, the modified uridine is pseudouridine. In some embodiments, the modified uridine is N1-methyl-pseudouridine. In some embodiments, the modified uridine is a combination of pseudouridine and N1-methyl-pseudouridine. In some embodiments, the modified uridine is a combination of pseudouridine and 5-methoxyuridine. In some embodiments, the modified uridine is a combination of N1-methylpseudouridine and 5-methoxyuridine. In some embodiments, the modified uridine is a combination of 5-iodouridine and N1-methyl-pseudouridine. In some embodiments, the modified uridine is a combination of pseudouridine and 5-iodouridine. In some embodiments, the modified uridine is a combination of 5-iodouridine and 5-methoxyuridine.

In some embodiments, 10% - 25%, 15 - 25%, 25 - 35%, 35 - 45%, 45 - 55%, 55 - 65%, 65 - 75%, 75 - 85%, 85 - 95%, or 90 - 100% of the uridine positions in the mRNA according to the present disclosure are modified uridines, such as 5-methoxyuridine, 5-iodouridine, N1-methylpseudouridine, pseudouridine, or a combination thereof. In some embodiments, 10% - 25%, 15 - 25%, 25 - 35%, 35 - 45%, 45 - 55%, 55 - 65%, 65 - 75%, 75 - 85%, 85 - 95%, or 90 - 100% of the uridine positions in the mRNA according to the present disclosure are 5-methoxyuridine. In some embodiments, 10% - 25%, 15 - 25%, 25 - 35%, 35 - 45%, 45 - 55%, 55 - 65%, 65 - 75%, 75 - 85%, 85 - 95%, or 90 - 100% of the uridine positions in the mRNA according to the present disclosure are pseudouridine. In some embodiments, 10% - 25%, 15 - 25%, 25 - 35%, 35 - 45%, 45 - 55%, 55 - 65%, 65 - 75%, 75 - 85%, 85 - 95%, or 90 - 100% of the uridine positions in the mRNA according to the present disclosure are N1-methylpseudouridine. In some embodiments, 10% - 25%, 15 - 25%, 25 - 35%, 35 - 45%, 45 - 55%, 55 - 65%, 65 - 75%, 75 - 85%, 85 - 95%, or 90 - 100% of the uridine positions in the mRNA according to the present disclosure are 5-iodouridine. In some embodiments, 10% - 25%, 15 - 25%, 25 - 35%, 35 - 45%, 45 - 55%, 55 - 65%, 65 - 75%, 75 - 85%, 85 - 95%, or 90 - 100% of the uridine positions in the mRNA according to the present disclosure are 5-methoxyuridine, and the remaining uridine positions are N1-methylpseudouridine.In some embodiments, 10% to 25%, 15% to 25%, 25% to 35%, 35% to 45%, 45% to 55%, 55% to 65%, 65% to 75%, 75% to 85%, 85% to 95%, or 90% to 100% of the uridine positions of the mRNA according to the present disclosure are 5-iodouridine, and the remaining uridine positions are N1-methylpseudouridine.
[0058] In any of the above embodiments, the modified ORF may include a low uridine nucleotide content, such as a uridine dinucleotide (UU) content as low as possible. For example, (a) using the minimum uridine codon (described above) at any position, and (b) an ORF encoding the same amino acid sequence as a given ORF. The uridine dinucleotide (UU) content can be expressed as an absolute value as the count of UU dinucleotides within the ORF, or as a ratio as the proportion of positions occupied by uridine of the uridine dinucleotide (for example, in the case of AUUAU, since 2 out of 5 positions are occupied by uridine of the uridine dinucleotide, the uridine dinucleotide content is 40%). To evaluate the minimum uridine dinucleotide content, modified uridine residues are considered equivalent to uridine.
[0059] In some embodiments, the mRNA includes at least one UTR derived from an expressed mammalian mRNA, such as a constitutively expressed mRNA. An mRNA is considered to be constitutively expressed in a mammal if it is continuously transcribed in at least one tissue of a healthy adult mammal. In some embodiments, the mRNA includes a 5'UTR, a 3'UTR, or both 5' and 3' UTRs derived from an expressed mammalian RNA, such as a constitutively expressed mammalian mRNA. Actin mRNA is an example of a constitutively expressed mRNA.
[0060] In some embodiments, the mRNA comprises at least one UTR derived from 17-beta-hydroxysteroid dehydrogenase 4 (HSD17B4 or HSD), such as a 5’UTR derived from HSD. In some embodiments, the mRNA comprises at least one UTR derived from globin mRNA, such as human alpha globin (HBA) mRNA, human beta globin (HBB) mRNA, or Xenopus laevis beta globin (XBG) mRNA. In some embodiments, the mRNA comprises a 5’UTR, a 3’UTR, or both 5’ and 3’ UTRs derived from globin mRNA, such as HBA, HBB, or XBG. In some embodiments, the mRNA comprises a 5’UTR derived from bovine growth hormone, cytomegalovirus (CMV), mouse Hba-a1, HSD, albumin gene, HBA, HBB, or XBG.

[0061] In some embodiments, the mRNA comprises both 5’ and 3’ UTRs derived from the same source, such as both 5’ and 3’ UTRs derived from constitutively expressed mRNAs such as actin, albumin, or globin, such as HBA, HBB, or XBG.
[0062] In some embodiments, the mRNA does not contain a 5’ UTR. For example, there are no additional nucleotides between the 5’ cap and the start codon. In some embodiments, the mRNA contains a Kozak sequence (described below) between the 5’ cap and the start codon, but there is no additional 5’ UTR. In some embodiments, the mRNA does not contain a 3’ UTR. For example, there are no additional nucleotides between the stop codon and the polyA tail.
[0063] In some embodiments, the mRNA contains a Kozak sequence. The Kozak sequence can affect translation initiation and the overall yield of the polypeptide translated from the mRNA. The Kozak sequence contains a methionine codon that can function as a start codon. The minimal Kozak sequence is NNNRUGN, and at least one of the following is true, i.e., the first N is A or G, and the second N is G. In a nucleotide sequence, R means a purine (A or G). In some embodiments, the Kozak sequence is RNNRUGN, NNNRUGG, RNNRUGG, RNNAUGN, NNNAUGG, or RNNAUGG. In some embodiments, the Kozak sequence is rccRUGg, with zero mismatches or at most one or two mismatches relative to the positions of the lowercase letters. In some embodiments, the Kozak sequence is rccAUGg, with zero mismatches or at most one or two mismatches relative to the positions of the lowercase letters. In some embodiments, the Kozak sequence is gccRccAUGG, with zero mismatches or at most one, two, or three mismatches relative to the positions of the lowercase letters. In some embodiments, the Kozak sequence is gccAccAUG, with zero mismatches or at most one, two, three, or four mismatches relative to the positions of the lowercase letters. In some embodiments, the Kozak sequence is GCCACCAUG.

[0074] In some embodiments, the mRNA disclosed herein includes a 5′ cap, such as Cap0, Cap1, or Cap2. The 5′ cap is generally a 7-methylguanosine ribonucleotide linked via a 5′-triphosphate to the 5′ position of the first nucleotide of the strand in the 5′ to 3′ direction of the mRNA (which may be further modified, e.g., with respect to ARCA, as discussed below), i.e., the first cap-proximal nucleotide. In Cap0, the riboses of the first and second cap-proximal nucleotides of the mRNA both contain a 2′-hydroxyl. In Cap1, the riboses of the first and second transcribed nucleotides of the mRNA contain 2′-methoxy and 2′-hydroxyl, respectively. In Cap2, the riboses of the first and second cap-proximal nucleotides of the mRNA both contain 2′-methoxy. See, e.g., Katibah et al. (2014) Proc Natl Acad Sci USA 111(33):12025-30, Abbas et al. (2017) Proc Natl Acad Sci USA 114(11):E2106-E2115. Most endogenous mRNAs of higher eukaryotes, including mammalian mRNAs such as human mRNAs, contain Cap1 or Cap2. Cap0, as well as other cap structures different from Cap1 and Cap2, may be immunogenic because they are recognized as “non-self” by components of the innate immune system, such as IFIT-1 and IFIT-5, in mammals such as humans, which can lead to elevated cytokine levels, including type I interferon. Components of the innate immune system, such as IFIT-1 and IFIT-5, may also compete with eIF4E for binding to mRNAs having caps other than Cap1 or Cap2, potentially inhibiting mRNA translation.
[0075] The cap can be included by co-transcription. For example, ARCA (anti-reverse cap analog; Thermo Fisher Scientific catalog number AM8045) is a cap analog that contains 7-methylguanosine 3'-methoxy-5'-triphosphate linked to the 5'-position of guanine ribonucleotide and can be incorporated into the transcription product during in vitro transcription initiation. In ARCA, it becomes a Cap0 cap where the 2'-position of the first cap-neighboring nucleotide is hydroxyl. See, for example, Stepinski et al., (2001) “Synthesis and properties of mRNAs containing the novel ‘anti-reverse’ cap analogs 7-methyl(3’-O-methyl)GpppG and 7-methyl(3’deoxy)GpppG,” RNA 7:1486-1495. The structure of ARCA is shown below. [Chemical formula]
[0076] When using CleanCap™ AG (m7G(5’)ppp(5’)(2’OMeA)pG; TriLink Biotechnologies catalog number N-7113) or CleanCap™ GG (m7G(5’)ppp(5’)(2’OMeG)pG; TriLink Biotechnologies catalog number N-7133), a Cap1 structure can be obtained by co-transcription. The 3’-O-methylated forms of CleanCap™ AG and CleanCap™ GG are also available from TriLink Biotechnologies as catalog numbers N-7413 and N-7433, respectively. The CleanCap™ AG structure is shown below. [Chemical formula]
[0077] Alternatively, a cap can be added to the RNA after transcription. For example, the vaccinia capping enzyme is commercially available (New England Biolabs catalog number M2080S), which has RNA triphosphatase activity and guanylyltransferase activity provided by its D1 subunit, as well as guanine methyltransferase provided by its D12 subunit. Thus, this enzyme can add 7-methylguanine to the RNA to give Cap0 in the presence of S-adenosylmethionine and GTP. See, for example, Guo, P. and Moss, B. (1990) Proc. Natl. Acad. Sci. USA 87, 4023-4027, Mao, X. and Shuman, S. (1994) J. Biol. Chem. 269, 24472-24479.
[0078] In some embodiments, the mRNA further comprises a polyadenylated (polyA) tail. In some embodiments, the polyA tail comprises at least 20, 30, 40, 50, 60, 70, 80, 90, or 100 adenines, optionally up to 300 adenines. In some embodiments, the polyA tail comprises 95, 96, 97, 98, 99, or 100 adenine nucleotides. In some examples, the polyA tail is "interrupted" by one or more non-adenine nucleotide "anchors" at one or more positions within the polyA tail. The polyA tail may comprise at least 8 consecutive adenine nucleotides, but also comprises one or more non-adenine nucleotides. As used herein, "non-adenine nucleotide" refers to any natural or non-natural nucleotide that does not contain adenine. Guanine, thymine, and cytosine nucleotides are exemplary non-adenine nucleotides. Thus, the polyA tail of the mRNA described herein may comprise consecutive adenine nucleotides located 3' to the RNA-induced DNA-binding factor or the nucleotide encoding the target sequence. In some examples, the polyA tail of the mRNA comprises non-consecutive adenine nucleotides located 3' to the RNA-induced DNA-binding factor or the nucleotide encoding the target sequence, where the adenine nucleotides are interrupted at regular or irregular intervals by non-adenine nucleotides.
[0079] In some embodiments, the mRNA further comprises a polyadenylated (polyA) tail. In some embodiments, the polyA tail comprises at least 20, 30, 40, 50, 60, 70, 80, 90, or 100 adenines, optionally up to 300 adenines. In some embodiments, the polyA tail comprises 95, 96, 97, 98, 99, or 100 adenine nucleotides. In some examples, the polyA tail is "interrupted" by one or more non-adenine nucleotide "anchors" at one or more positions within the polyA tail. The polyA tail may comprise at least 8 consecutive adenine nucleotides, but also comprises one or more non-adenine nucleotides. As used herein, "non-adenine nucleotide" refers to any natural or non-natural nucleotide that does not contain adenine. Guanine, thymine, and cytosine nucleotides are exemplary non-adenine nucleotides. Thus, the polyA tail of the mRNA described herein may comprise consecutive adenine nucleotides located 3' to the RNA-induced DNA-binding factor or the nucleotide encoding the target sequence. In some examples, the polyA tail of the mRNA comprises non-consecutive adenine nucleotides located 3' to the RNA-induced DNA-binding factor or the nucleotide encoding the target sequence, where the adenine nucleotides are interrupted at regular or irregular intervals by non-adenine nucleotides.
[0080] In some embodiments, one or more non-adenine nucleotides are arranged to interrupt consecutive adenine nucleotides so that poly(A)-binding proteins can bind to a long extended region of consecutive adenine nucleotides. In some embodiments, one or more non-adenine nucleotide(s) are positioned after at least 8, 9, 10, 11, or 12 consecutive adenine nucleotides. In some embodiments, one or more non-adenine nucleotide(s) are positioned after at least 8 to 50 consecutive adenine nucleotides. In some embodiments, one or more non-adenine nucleotide(s) are positioned after at least 8 to 100 consecutive adenine nucleotides. In some embodiments, a non-adenine nucleotide is after 1, 2, 3, 4, 5, 6, or 7 adenine nucleotides, followed by at least 8 consecutive adenine nucleotides.
[0081] The poly-A tail may include one sequence of consecutive adenine nucleotides, followed by one or more non-adenine nucleotides, optionally followed by additional adenine nucleotides.
[0082] In some embodiments, the poly-A tail includes or contains one non-adenine nucleotide or a long region where 2 to 10 non-adenine nucleotides are consecutive. In some embodiments, one or more non-adenine nucleotide(s) are positioned after at least 8, 9, 10, 11, or 12 consecutive adenine nucleotides. In some examples, one or more non-adenine nucleotide(s) are positioned after at least 8 to 50 consecutive adenine nucleotides. In some embodiments, one or more non-adenine nucleotide(s) are positioned after at least 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, or 50 consecutive adenine nucleotides.
[0083] In some embodiments, the non-adenine nucleotide is guanine, cytosine, or thymine. In some examples, the non-adenine nucleotide is a guanine nucleotide. In some embodiments, the non-adenine nucleotide is a cytosine nucleotide. In some embodiments, the non-adenine nucleotide is a thymine nucleotide. In some examples where two or more non-adenine nucleotides are present, the non-adenine nucleotides may be selected from a) guanine nucleotides and thymine nucleotides, b) guanine nucleotides and cytosine nucleotides, c) thymine nucleotides and cytosine nucleotides, or d) guanine nucleotides, thymine nucleotides, and cytosine nucleotides. An exemplary polyA tail containing non-adenine nucleotides is described as SEQ ID NO: 62.
[0084] In some embodiments, the mRNA is purified. In some embodiments, precipitation methods (e.g., LiCl precipitation, alcohol precipitation, etc., or equivalent methods, e.g., the methods described herein) are used to purify the mRNA. In some embodiments, methods using chromatography, such as methods using HPLC or equivalent methods (e.g., the methods described herein), are used to purify the mRNA. In some embodiments, both a precipitation method (e.g., LiCl precipitation) and a method using HPLC are used to purify the mRNA.
[0085] In some embodiments, at least one gRNA is provided in combination with the mRNA disclosed herein. In some embodiments, the gRNA is provided as a separate molecule from the mRNA. In some embodiments, the gRNA is provided as part of the mRNA disclosed herein, e.g., as part of the UTR.
[0086] Chemically modified gRNA In some embodiments, the gRNA is chemically modified. A gRNA containing one or more modified nucleosides or nucleotides is referred to as a "modified" gRNA or a "chemically modified" gRNA, and represents that non-naturally occurring components or configurations are used in place of or in addition to the standard residues A, G, C, and U, and / or that one or more naturally occurring components or configurations are present. In some embodiments, the modified gRNA is synthesized using non-standard nucleosides or nucleotides, which are referred to herein as "modifications". Modified nucleosides and modified nucleotides include (i) one or both of the non-bridging oxygens of the phosphate group in the phosphodiester backbone bond and / or one or more changes in the bridging oxygens of the phosphate group, such as substitution (exemplary backbone modifications), (ii) changes in the components of the ribose sugar, such as the hydroxyl at the 2'-position of the ribose sugar, such as substitution (exemplary sugar modifications), (iii) substantial substitution of the phosphate moiety with a "dephospho" linker (exemplary backbone modifications), (iv) modification or substitution of naturally occurring nucleobases, such as using non-standard nucleobases (exemplary base modifications), (v) substitution or modification of the ribose-phosphate backbone (exemplary backbone modifications), (vi) modification of the 3'- or 5'-end of the oligonucleotide, such as removing, modifying or substituting the terminal phosphate group, or attaching a moiety, cap or linker (such 3'- or 5'-cap modifications may include sugar modifications and / or backbone modifications), and (vii) one or more of sugar modifications or substitutions (exemplary sugar modifications).
[0087] In some embodiments, the gRNA comprises a modified uridine at some or all of the uridine positions. In some embodiments, the modified uridine is a uridine modified at the 5-position, for example, with a halogen or a C1-C6 alkoxy. In some embodiments, the modified uridine is a pseudouridine modified at the 1-position, for example, with a C1-C6 alkyl. The modified uridine can be, for example, pseudouridine, N1-methyl-pseudouridine, 5-methoxyuridine, 5-iodouridine, or a combination thereof. In some embodiments, the modified uridine is 5-methoxyuridine. In some embodiments, the modified uridine is 5-iodouridine. In some embodiments, the modified uridine is pseudouridine. In some embodiments, the modified uridine is N1-methyl-pseudouridine. In some embodiments, the modified uridine is a combination of pseudouridine and N1-methyl-pseudouridine.

In some embodiments, the modified uridine is a combination of N1-methylpseudouridine and 5-methoxyuridine. In some embodiments, the modified uridine is a combination of 5-iodouridine and N1-methyl-pseudouridine. In some embodiments, the modified uridine is a combination of pseudouridine and 5-iodouridine. In some embodiments, the modified uridine is a combination of 5-iodouridine and 5-methoxyuridine.
[0088] In some embodiments, at least 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 98%, 99%, or 100% of the uridine positions of the gRNA according to the present disclosure are modified uridines. In some embodiments, 10% - 25%, 15 - 25%, 25 - 35%, 35 - 45%, 45 - 55%, 55 - 65%, 65 - 75%, 75 - 85%, 85 - 95%, or 90 - 100% of the uridine positions of the gRNA according to the present disclosure are modified uridines, such as 5-methoxyuridine, 5-iodouridine, N1-methylpseudouridine, pseudouridine, or a combination thereof. In some embodiments, 10% - 25%, 15 - 25%, 25 - 35%, 35 - 45%, 45 - 55%, 55 - 65%, 65 - 75%, 75 - 85%, 85 - 95%, or 90 - 100% of the uridine positions of the gRNA according to the present disclosure are 5-methoxyuridine. In some embodiments, 10% - 25%, 15 - 25%, 25 - 35%, 35 - 45%, 45 - 55%, 55 - 65%, 65 - 75%, 75 - 85%, 85 - 95%, or 90 - 100% of the uridine positions of the gRNA according to the present disclosure are pseudouridine. In some embodiments, 10% - 25%, 15 - 25%, 25 - 35%, 35 - 45%, 45 - 55%, 55 - 65%, 65 - 75%, 75 - 85%, 85 - 95%, or 90 - 100% of the uridine positions of the gRNA according to the present disclosure are N1-methylpseudouridine. In some embodiments, 10% - 25%, 15 - 25%, 25 - 35%, 35 - 45%, 45 - 55%, 55 - 65%, 65 - 75%, 75 - 85%, 85 - 95%, or 90 - 100% of the uridine positions of the gRNA according to the present disclosure are 5-iodouridine. In some embodiments, 10% - 25%, 15 - 25%, 25 - 35%, 35 - 45%, 45 - 55%, 55 - 65%, 65 - 75%, 75 - 85%, 85 - 95%, or 90 - 100% of the uridine positions of the gRNA according to the present disclosure are 5-methoxyuridine and the remaining uridine positions are N1-methylpseudouridine.In some embodiments, 10% to 25%, 15% to 25%, 25% to 35%, 35% to 45%, 45% to 55%, 55% to 65%, 65% to 75%, 75% to 85%, 85% to 95%, or 90% to 100% of the uridine positions of the gRNA according to the present disclosure are 5-iodouridine, and the remaining uridine positions are N1-methylpseudouridine.
[0089] By combining the chemical modifications as described above, modified gRNAs can be obtained that contain nucleosides and nucleotides (collectively referred to as "residues") having two, three, four, or more modifications. For example, the modified residues can have modified sugars and modified nucleobases. In some embodiments, all bases of the gRNA are modified, for example, all bases have a modified phosphate group such as a phosphorothioate group. In certain embodiments, all or substantially all of the phosphate groups of the gRNA molecule are replaced with phosphorothioate groups. In some embodiments, the modified gRNA contains at least one modified residue at or near the 5' end of the RNA. In some embodiments, the modified gRNA contains at least one modified residue at or near the 3' end of the RNA.
[0090] In some embodiments, the gRNA contains one, two, three, or more modified residues. In some embodiments, at least 5% (e.g., at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or 100%) of the positions of the modified gRNA are modified nucleosides or nucleotides.
[0091] Unmodified nucleic acids can tend to be degraded, for example, by nucleases found intracellularly or in serum. For example, nucleases can hydrolyze the phosphodiester bonds of nucleic acids. Thus, in one aspect, the gRNAs described herein can contain one or more modified nucleosides or nucleotides to introduce, for example, stability against nucleases intracellularly or in serum. In some embodiments, the modified gRNA molecules described herein can exhibit a low innate immune response when introduced into a cell population, either in vivo or ex vivo. The term "innate immune response" includes cellular responses to foreign nucleic acids such as single-stranded nucleic acids, and includes the expression and release of cytokines, particularly the release of interferons, as well as the induction of cell death.
[0092] In some embodiments of backbone modification, the phosphate group of the modified residue can be modified by replacing one or more of the oxygens with different substituents. Further, modified residues, for example, those present in a modified nucleic acid, can include substantial replacement of the unmodified phosphate moiety with the modified phosphate groups described herein. In some embodiments, backbone modification of the phosphate backbone can include changes that result in either an uncharged linker or a charged linker with an asymmetric charge distribution.
[0093] Examples of modified phosphate groups include phosphorothioate, phosphor selenate, borano phosphate, borano phosphate ester, hydrogen phosphonate, phosphoramidate, alkyl phosphonate or aryl phosphonate, and phosphotriester. The phosphorus atom of an unmodified phosphate group is achiral. However, by replacing one of the non-bridging oxygens with one of the above atoms or atomic groups, the phosphorus atom can be made chiral. The asymmetric phosphorus atom can have either an "R" configuration (Rp herein) or an "S" configuration (Sp herein). The backbone can also be modified by replacing the bridging oxygen (i.e., the oxygen connecting the phosphate group and the nucleoside) with nitrogen (bridging phosphoramidate), sulfur (bridging phosphorothioate), and carbon (bridging methylene phosphonate). The replacement can occur at either one or both of the connecting oxygens.
[0094] In certain backbone modifications, the phosphate group can be replaced with a phosphorus-free linker. In some embodiments, the charged phosphate group can be replaced with a neutral moiety. Examples of moieties that can replace the phosphate group include, without limitation, for example, methylphosphonate, hydroxylamino, siloxane, carbonate, carboxymethyl, carbamate, amide, thioether, ethylene oxide linker, sulfonate, sulfonamide, thioformacetal, formacetal, oxime, methyleneimino, methylene methylimino, methylene hydrazo, methylene dimethylhydrazo, and methylene oxymethylimino.
[0095] template nucleic acid The compositions and methods disclosed herein may include a template nucleic acid. The template may be used to alter or insert a nucleic acid sequence at or near the target site of a Cas nuclease. In some embodiments, the method includes introducing the template into a cell. In some embodiments, a single template may be provided. In other embodiments, two or more templates may be provided such that editing occurs at two or more target sites. For example, different templates may be provided to edit a single gene of a cell or two different genes of a cell.
[0096] In some embodiments, the template may be used in homologous recombination. In some embodiments, homologous recombination may result in the incorporation of the template sequence or a portion of the template sequence into the target nucleic acid molecule. In other embodiments, the template may be used in homologous recombination repair where DNA strand invasion occurs at the cleavage site of the nucleic acid. In some embodiments, homologous recombination repair may result in the template sequence being included within the edited target nucleic acid molecule. In yet another embodiment, the template may be used in gene editing mediated by non-homologous end joining. In some embodiments, the template sequence has no similarity to the nucleic acid sequence near the cleavage site. In some embodiments, the template or a portion of the template sequence is incorporated. In some embodiments, the template includes adjacent terminal inverted repeat (ITR) sequences.
[0097] In some embodiments, the template may include a first homology arm and a second homology arm (also referred to as a first nucleotide sequence and a second nucleotide sequence) that are complementary to sequences located upstream and downstream, respectively, of each cleavage site. When the template contains two homology arms, each arm may be of the same or different lengths, and the sequence flanked by the homology arms may be substantially similar or identical to the target sequence flanked by the homology arms, or may be an entirely unrelated sequence. In some embodiments, the degree of complementarity or percent identity between the first nucleotide sequence on the template and the sequence upstream of the cleavage site, and the degree of complementarity or percent identity between the second nucleotide sequence on the template and the sequence downstream of the cleavage site may enable homologous recombination between the template and the target nucleic acid molecule, such as high-fidelity homologous recombination. In some embodiments, the degree of complementarity may be about 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99%, or 100%. In some embodiments, the degree of complementarity may be about 95%, 97%, 98%, 99%, or 100%. In some embodiments, the degree of complementarity may be at least 98%, 99%, or 100%. In some embodiments, the degree of complementarity may be 100%. In some embodiments, the percent identity may be about 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99%, or 100%. In some embodiments, the percent identity may be about 95%, 97%, 98%, 99%, or 100%. In some embodiments, the percent identity may be at least 98%, 99%, or 100%. In some embodiments, the percent identity may be 100%.
[0098] In some embodiments, the template array may correspond to, include, or consist of the endogenous sequence of the target cell. Additionally, or alternatively, the template array may correspond to, include, or consist of an exogenous sequence of the target cell. As used herein, the term "endogenous sequence" refers to a sequence that is native to the cell. The term "exogenous sequence" refers to a sequence that is not native to the cell, or a sequence whose native location in the genome of the cell is at a different location. In some embodiments, the endogenous sequence may be the genomic sequence of the cell. In some embodiments, the endogenous sequence may be a chromosomal sequence or an extrachromosomal sequence. In some embodiments, the endogenous sequence may be a plasmid sequence of the cell. In some embodiments, the template array may be substantially identical to a portion of the endogenous sequence of the cell at or near the cleavage site, but includes at least one nucleotide change. In some embodiments, editing the cleaved target nucleic acid molecule using the template can result in a mutation that includes the insertion, deletion, or substitution of one or more nucleotides of the target nucleic acid molecule. In some embodiments, the mutation can result in a change in one or more amino acids in the protein expressed by the gene containing the target sequence. In some embodiments, the mutation can result in a change in one or more nucleotides in the RNA expressed by the target gene. In some embodiments, the mutation can change the expression level of the target gene. In some embodiments, the mutation can result in an increase or decrease in the expression of the target gene.

In some embodiments, editing the cleaved target nucleic acid molecule using the template can result in a change in the exon sequence, intron sequence, regulatory sequence, transcriptional regulatory sequence, translational regulatory sequence, splicing site, or non-coding sequence of the target nucleic acid molecule, such as DNA.
[0099] In other embodiments, the template array may include foreign sequences. In some embodiments, the foreign sequence may include a sequence encoding a protein or RNA operably linked to a heterologous promoter sequence, such that when the foreign sequence is integrated into the target nucleic acid molecule, the cell can express the protein or RNA encoded by such an integrated sequence. In other embodiments, when the foreign sequence is integrated within the target nucleic acid molecule, expression of such an integrated sequence may be controlled by an endogenous promoter sequence. In some embodiments, the foreign sequence may provide a cDNA sequence encoding a protein or a portion of the protein. In yet another embodiment, the foreign sequence may comprise or consist of an exon sequence, an intron sequence, a control sequence, a transcriptional control sequence, a translational control sequence, a splicing site, or a non-coding sequence. In some embodiments, integration of the foreign sequence may result in restoration of gene function. In some embodiments, integration of the foreign sequence may result in gene knock-in.

In some embodiments, the template may contain a homology arm complementary to a sequence located upstream or downstream of a cleavage site on the target nucleic acid molecule.
[0101] In some embodiments, the template contains ssDNA or dsDNA in which terminal inverted repeat (ITR) sequences are contained adjacent to each other. In some embodiments, the template is provided as a vector, plasmid, minicircle, nanocircle, or PCR product.
[0102] Purification of Nucleic Acids In some embodiments, nucleic acids are purified. In some embodiments, precipitation methods (e.g., LiCl precipitation, alcohol precipitation, or equivalent methods, such as the methods described herein) are used to purify nucleic acids. In some embodiments, chromatography methods or equivalent methods (e.g., the methods described herein), such as methods using HPLC, are used to purify nucleic acids. In some embodiments, both a precipitation method (e.g., LiCl precipitation) and a method using HPLC are used to purify nucleic acids.
[0103] Target sequence In some embodiments, the CRISPR / Cas system of the present disclosure may be oriented to and cleave a target sequence on a target nucleic acid molecule. For example, the target sequence may be recognized and cleaved by a Cas nuclease. In certain embodiments, the target sequence of the Cas nuclease is located in the vicinity of the specific PAM sequence of such nuclease. In some embodiments, a class 2 Cas nuclease is oriented to the target sequence of the target nucleic acid molecule by a gRNA, where the gRNA hybridizes to the target sequence and the class 2 Cas protein may cleave the target sequence. In some embodiments, the guide RNA hybridizes to a target sequence adjacent to or including the specific PAM of the class 2 Cas nuclease, and the class 2 Cas nuclease cleaves such target sequence. In some embodiments, the target sequence may be complementary to the targeting sequence of the guide RNA. In some embodiments, the degree of complementarity between the targeting sequence of the guide RNA and the corresponding portion of the target sequence to which the guide RNA hybridizes may be about 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99%, or 100%. In some embodiments, the percent identity between the targeting sequence of the guide RNA and the corresponding portion of the target sequence to which the guide RNA hybridizes may be about 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99%, or 100%. In some embodiments, the target homology region is adjacent to the specific PAM sequence. In some embodiments, the target sequence may include a sequence that is 100% complementary to the targeting sequence of the guide RNA. In other embodiments, the target sequence may include at least one mismatch, deletion, or insertion compared to the targeting sequence of the guide RNA.
[0104] The length of the target sequence may vary depending on the nuclease system used. For example, the targeting sequence of a guide RNA for the CRISPR / Cas system may include a nucleotide length of 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 35, 40, 45, 50, or more than 50 nucleotides, the target sequence is of the corresponding length, and optionally adjacent to the PAM sequence. In some embodiments, the target sequence may include a length of 15 to 24 nucleotides. In some embodiments, the target sequence may include a length of 17 to 21 nucleotides. In some embodiments, the target sequence may include a length of 20 nucleotides. When using a nickase, the target sequence may include a pair of target sequences recognized by a pair of nickases that cleave opposite strands of a DNA molecule. In some embodiments, the target sequence may include a pair of target sequences recognized by a pair of nickases that cleave the same strand of a DNA molecule. In some embodiments, the target sequence may include a portion of a target sequence recognized by one or more Cas nucleases.
[0105] The target nucleic acid molecule may be any DNA molecule or RNA molecule that is endogenous or exogenous to the cell. In some embodiments, the target nucleic acid molecule may be cell-derived or intracellular episomal DNA, plasmid, genomic DNA, viral genome, mitochondrial DNA, or chromosomal DNA. In some embodiments, the target sequence of the target nucleic acid molecule may be a genomic sequence derived from or within a cell such as a human cell.

In yet another embodiment, the target sequence may be a synthetic sequence. In further embodiments, the target sequence may be a chromosomal sequence. In certain embodiments, the target sequence may include a translocation junction, e.g., a translocation associated with cancer. In some embodiments, the target sequence may be on the chromosome of a eukaryote such as a human chromosome. In certain embodiments, the target sequence is a liver-specific sequence, in which case the sequence is expressed in hepatocytes.
[0107] In some embodiments, the target sequence may be located within the coding sequence of a gene, within the intron sequence of a gene, within a regulatory sequence, within the transcriptional regulatory sequence of a gene, within the translational regulatory sequence of a gene, at a splicing site, or within the non-coding sequence between genes. In some embodiments, the gene may be a gene encoding a protein. In other embodiments, the gene may be a non-coding RNA gene. In some embodiments, the target sequence may include all or part of a disease-related gene. In some embodiments, the target sequence may be located at a non-gene functional site of the genome, for example, a site that controls the flank of chromatin organization such as a scaffold site or a locus control region.
[0108] In embodiments involving a Cas nuclease, such as a Class 2 Cas nuclease, the target sequence may be adjacent to a protospacer adjacent motif (PAM). In some embodiments, the PAM may be adjacent to the 3’ end of the target sequence or within 1, 2, 3, or 4 nucleotides thereof. The length and sequence of the PAM may vary depending on the Cas protein used. For example, the PAM may be selected from a consensus sequence for a particular Cas9 protein or Cas9 ortholog or a particular PAM sequence, including those disclosed in FIG. 1 of Ran et al., Nature, 520:186-191 (2015) and FIG. S5 of Zetsche 2015, each of which is incorporated herein by reference. In some embodiments, the PAM may be 2, 3, 4, 5, 6, 7, 8, 9, or 10 nucleotides in length. Non-limiting exemplary PAM sequences include NGG, NGGNG, NG, NAAAAN, NNNAAAW, NNNNACA, GNNNCNNA, TTN, and NNNNGATT (where N is defined as any nucleotide and W is defined as either A or T). In some embodiments, the PAM sequence may be NGG. In some embodiments, the PAM sequence may be NGGNG. In some embodiments, the PAM sequence may be TTN. In some embodiments, the PAM sequence may be NNNAAAW.
[0109] Lipid formulation This specification discloses various embodiments of LNP formulations of RNA, such as CRISPR / Cas cargo. Such LNP formulations include "amine lipids" together with helper lipids, neutral lipids, and PEG lipids. In some embodiments, such LNP formulations include "amine lipids" together with helper lipids and PEG lipids. In some embodiments, the LNP formulation includes less than 1 percent neutral phospholipid. In some embodiments, the LNP formulation includes less than 0.5 percent neutral phospholipid. "Lipid nanoparticles" mean particles comprising a plurality (i.e., two or more) of lipid molecules physically associated with each other by intermolecular forces.
[0110] Amine lipid An LNP composition for delivering a biologically active agent includes an "amine lipid" defined as lipid A or its equivalent, such as an acetal analog of lipid A.
[0111] In some embodiments, the amine lipid is lipid A, which is (9Z,12Z)-3-((4,4-bis(octyloxy)butanoyl)oxy)-2-((((3-(diethylamino)propoxy)carbonyl)oxy)methyl)propyl octadeca-9,12-dienoate and is also referred to as 3-((4,4-bis(octyloxy)butanoyl)oxy)-2-((((3-(diethylamino)propoxy)carbonyl)oxy)methyl)propyl (9Z,12Z)-octadeca-9,12-dienoate. Lipid A is
Chemical formula
[0112] Lipid A may be synthesized according to WO2015 / 095340 (e.g., pages 84-86). In certain embodiments, the amine lipid is an equivalent of lipid A.
[0113] In certain embodiments, the amine lipid is an analog of lipid A. In certain embodiments, the lipid A analog is an acetal analog of lipid A. In certain LNP compositions, the acetal analog is a C4-C12 acetal analog. In some embodiments, the acetal analog is a C5-C12 acetal analog. In further embodiments, the acetal analog is a C5-C10 acetal analog. In further embodiments, the acetal analog is selected from the acetal analogs of C4, C5, C6, C7, C9, C10, C11, and C12.
[0114] The amine lipids suitable for use in the LNPs described herein are biodegradable in vivo and are suitable for delivering biologically active substances such as RNA to cells. The amine lipids are of low toxicity (e.g., tolerated in animal models with an RNA cargo amount of 10 mg / kg or more and having no adverse effects). In certain embodiments, the LNPs containing the amine lipid include those in which at least 75% of the amine lipid disappears from the plasma within 8 hours, within 10 hours, within 12 hours, within 24 hours, or within 48 hours, or within 3 days, within 4 days, within 5 days, within 6 days, within 7 days, or within 10 days. In certain embodiments, the LNPs containing the amine lipid include those in which at least 50% of the mRNA or gRNA disappears from the plasma within 8 hours, within 10 hours, within 12 hours, within 24 hours, or within 48 hours, or within 3 days, within 4 days, within 5 days, within 6 days, within 7 days, or within 10 days. In certain embodiments, the LNPs containing the amine lipid include those in which, for example, at least 50% of the LNP (measuring lipids (e.g., amine lipids), RNA (e.g., mRNA), or another component) disappears from the plasma within 8 hours, within 10 hours, within 12 hours, within 24 hours, or within 48 hours, or within 3 days, within 4 days, within 5 days, within 6 days, within 7 days, or within 10 days. In certain embodiments, the lipid, RNA, or nucleic acid component of the LNP is measured in both the encapsulated and free forms with respect to the lipid.
[0115] Lipid clearance may be measured as described in the literature. See Maier, M.A., et al. Biodegradable Lipids Enabling Rapidly Eliminated Lipid Nanoparticles for Systemic Delivery of RNAi Therapeutics. Mol. Ther. 2013, 21(8), 1570-78 (“Maier”). For example, in Maier, an LNP-siRNA system containing luciferase-directed siRNA was administered to 6- to 8-week-old male C57Bl / 6 mice at 0.3 mg / kg via intravenous bolus injection through the lateral tail vein. Samples of blood, liver, and spleen were collected 0.083 hours, 0.25 hours, 0.5 hours, 1 hour, 2 hours, 4 hours, 8 hours, 24 hours, 48 hours, 96 hours, and 168 hours after administration. The mice were perfused with saline and then the tissues were collected, and the blood samples were processed to obtain plasma. All samples were processed and analyzed by LC-MS. Further, Maier describes methods for toxicity assessment after administration of the LNP-siRNA formulation. For example, luciferase-directed siRNA was administered to male Sprague-Dawley rats at 0 mg / kg, 1 mg / kg, 3 mg / kg, 5 mg / kg, and 10 mg / kg (5 animals / group) at a dose volume of 5 mL / kg by single intravenous bolus injection. After 24 hours, approximately 1 mL of blood was obtained from the jugular vein of the awake animals and serum was isolated. Seventy-two hours after administration, all animals were euthanized for necropsy. Clinical signs, body weight, serum chemistry, organ weight, and histopathology were evaluated. Maier describes methods for evaluating siRNA-LNP formulations, and these methods may be applied to the evaluation of clearance, pharmacokinetics, and toxicity regarding administration of the LNP compositions of the present disclosure.
[0116] Amine lipids can cause an increase in clearance rate. In some embodiments, the clearance rate is the lipid clearance rate, e.g., the rate at which lipids disappear from blood, serum, or plasma. In some embodiments, the clearance rate is the RNA clearance rate, e.g., the rate at which mRNA or gRNA disappears from blood, serum, or plasma. In some embodiments, the clearance rate is the rate at which LNPs disappear from blood, serum, or plasma. In some embodiments, the clearance rate is the rate at which LNPs disappear from tissues such as liver tissue or spleen tissue. In certain embodiments, a high clearance rate results in a safety profile with substantially no adverse effects. Amine lipids can reduce the accumulation of LNPs in circulation and in tissues. In some embodiments, the reduction in the accumulation of LNPs in circulation and in tissues results in a safety profile with substantially no adverse effects.
[0117] The amine lipids of the present disclosure can be ionized (e.g., form salts) depending on the pH of the medium in which they are contained. For example, in a slightly acidic medium, the amine lipid may be protonated and thus carry a positive charge. Conversely, in a slightly basic medium with a pH of about 7.35, such as blood, the amine lipid may not be protonated and thus may not carry a charge. In some embodiments, the amine lipids of the present disclosure can be protonated at a pH of at least about 9. In some embodiments, the amine lipids of the present disclosure can be protonated at a pH of at least about 9. In some embodiments, the amine lipids of the present disclosure can be protonated at a pH of at least about 10.
[0118] The pH at which the amine lipid is predominantly protonated is related to its intrinsic pKa. In some embodiments, each of the amine lipids of the present disclosure may independently have a pKa in the range of about 5.1 to about 7.4. In some embodiments, each of the amine lipids of the present disclosure may independently have a pKa in the range of about 5.5 to about 6.6. In some embodiments, each of the amine lipids of the present disclosure may independently have a pKa in the range of about 5.6 to about 6.4. In some embodiments, each of the amine lipids of the present disclosure may independently have a pKa in the range of about 5.8 to about 6.2. For example, each of the amine lipids of the present disclosure may independently have a pKa in the range of about 5.8 to about 6.5. Since cationic lipids with a pKa in the range of about 5.1 to about 7.4 have been found to be effective in delivering cargo in vivo, for example, to the liver, etc., the pKa of the amine lipid can be an important consideration in the formulation of LNPs. Furthermore, cationic lipids with a pKa in the range of about 5.3 to about 6.4 have been found to be effective in delivering in vivo, for example, to tumors. See, for example, WO2014 / 136086.

In one embodiment, the neutral phospholipid may be selected from the group consisting of distearoylphosphatidylcholine (DSPC) and dimyristoylphosphatidylethanolamine (DMPE). In another embodiment, the neutral phospholipid may be distearoylphosphatidylcholine (DSPC).In another embodiment, the neutral lipid may be dipalmitoyl phosphatidylcholine (DPPC).

In one embodiment, the helper lipid may be cholesterol. In one embodiment, the helper lipid may be cholesterol hemisuccinate.
[0121] The PEG lipid is a stealth lipid that changes the length of time the nanoparticles can exist in vivo (e.g., in the blood). The PEG lipid can assist in the formulation process, for example, by suppressing particle aggregation and controlling the particle size. The pharmacokinetic properties of the LNP can be regulated by the PEG lipid used herein. Typically, the PEG lipid includes a lipid moiety and a polymer moiety based on PEG.
[0122] In some embodiments, the lipid moiety can be obtained from a dialkylglycerol or a dialkylglycamide, which independently includes a dialkylglycerol group or a dialkylglycamide group containing saturated or unsaturated carbon atoms with an alkyl chain length of about C4 to about C40, where such chains may include one or more functional groups such as, for example, an amide or an ester. In some embodiments, the alkyl chain length includes from about C10 to C20. The dialkylglycerol group or the dialkylglycamide group can further include one or more substituted alkyl groups. The chain length may be symmetric or asymmetric.
[0123] Unless otherwise specified, the term "PEG" as used herein means any polyethylene glycol or other polyalkylene ether polymer. In one embodiment, the PEG moiety is a linear or branched polymer of ethylene glycol or ethylene oxide, optionally substituted. Alternatively, the PEG moiety may be substituted, for example, by one or more alkyl groups, alkoxy groups, acyl groups, hydroxy groups, or aryl groups. In one embodiment, the PEG moiety includes PEG copolymers such as PEG-polyurethane or PEG-polypropylene (see, for example, J. Milton Harris, Poly(ethylene glycol) chemistry: biotechnical and biomedical applications (1992)), and alternatively, the PEG moiety does not include a PEG copolymer and may be, for example, a PEG homopolymer. In one embodiment, the PEG has a molecular weight of from about 130 to about 50,000, in a sub-embodiment from about 150 to about 30,000, in a sub-embodiment from about 150 to about 20,000, in a sub-embodiment from about 150 to about 15,000, in a sub-embodiment from about 150 to about 10,000, in a sub-embodiment from about 150 to about 6,000, in a sub-embodiment from about 150 to about 5,000, in a sub-embodiment from about 150 to about 4,000, in a sub-embodiment from about 150 to about 3,000, in a sub-embodiment from about 300 to about 3,000, in a sub-embodiment from about 1,000 to about 3,000, and in a sub-embodiment from about 1,500 to about 2,500.
[0124] In certain embodiments, the PEG (e.g., attached to a lipid moiety such as a stealth lipid or a lipid) is "PEG-2K", also referred to as "PEG 2000", and has an average molecular weight of about 2,000 daltons. PEG-2K is represented herein by the following formula (I)

Example
[0174] Example 1 - LNP Composition for In Vivo Editing in Mice Small-scale preparations of various LNP compositions were prepared and their properties were examined. In assays for the editing ratio in the liver in mice, Cas9 mRNA and chemically modified mouse TTR sequence-directed sgRNA were formulated in LNP, with the mol% of PEG, the mol% of lipid A, and the N:P ratio varied as described in Table 2 below.
Table 2
[0175] In Figure 1, the LNP formulations are identified on the x-axis based on their lipid A mol% and N:P ratio, represented as “%CL;N:P”. As shown in the legend of Figure 1, PEG-2k-DMG at concentrations of 2 mol%, 2.5 mol%, 3 mol%, 4 mol%, or 5 mol% was formulated with (1) 45 mol% lipid A; N:P ratio 4.5 (“45;4.5”), (2) 45 mol% lipid A; N:P ratio 6 (“45;6”), (3) 50 mol% lipid A; N:P ratio 4.5 (“50;4.5”), (4) 50 mol% lipid A; N:P ratio 6 (“50;6”), (5) 55 mol% lipid A; N:P ratio 4.5 (“55;4.5”), and (6) 55 mol% lipid A; N:P ratio 6 (“55;6”). The mol% of DSPC was kept constant at 9 mol%, and cholesterol (mol%) was added so that the remainder of the lipid component of each formulation was 100 mol%. Each of the 30 formulations was formulated as described below and administered as a single dose at a total RNA dose of 1 mg / kg or 0.5 mg / kg (Figure 1A and Figure 1B, respectively).
[0176] LNP formulation - NanoAssemblr The lipid nanoparticle components were dissolved in 100% ethanol at the above molar ratios of the lipid components. The RNA cargo was dissolved in 25 mM citrate, 100 mM NaCl, pH 5.0, and the concentration of the RNA cargo was adjusted to approximately 0.45 mg / mL. The LNP was formulated with a molar ratio of lipid amine to RNA phosphate (N:P) of approximately 4.5 or approximately 6 and an mRNA to gRNA ratio of 1:1 by weight.
[0177] The Precision Nanosystems NanoAssemblr (trademark) Benchtop Instrument was used according to the manufacturer's operating procedures to generate LNPs by microfluidic mixing of lipids and RNA solution. Different flow rates were used while maintaining the ratio of aqueous solvent to organic solvent at 2:1 during mixing. After mixing, the LNPs were recovered, diluted in water (approx. 1:1 v / v), held at room temperature for 1 hour, further diluted in water (approx. 1:1 v / v), and then the final buffer exchange was performed. The final buffer exchange to 50 mM Tris, 45 mM NaCl, 5% (w / v) sucrose, pH 7.5 (TSS) was completed using a PD-10 desalting column (GE). If necessary, the formulation was concentrated by centrifugation using an Amicon 100 kDa centrifugal filter (Millipore). Subsequently, the resulting mixture was filtered using a 0.2 μm sterile filter. The final LNPs were stored at -80 °C until further use.
[0178] Formulation analysis method For the characterization of the polydispersity index ("pdi") and size of the LNPs of the present disclosure, dynamic light scattering method ("DLS") is used. DLS measures the scattering of light obtained by irradiating a sample with a light source. The PDI determined from DLS measurements represents the particle size (approximate average particle size) distribution in the population, and in the case of a completely homogeneous population, the PDI is zero.
[0179] Electrophoretic light scattering method is used for the characterization of the surface charge of LNPs at a specific pH. The surface charge, or zeta potential, is a measure of the magnitude of the electrostatic repulsive / attractive forces between particles in an LNP suspension.
[0180] Using asymmetric flow field-flow fractionation-multi-angle light scattering (AF4-MALS), particles in the formulation are separated by hydrodynamic radius, and then the molecular weight, hydrodynamic radius, and root mean square radius of the fractionated particles are measured. This enables the evaluation of the molecular weight and particle size distribution as well as secondary characteristics such as the Burchard-Stockmeyer plot (the ratio of the root mean square ("rms") radius to the hydrodynamic radius over time, which suggests the core density of the particle) and the rms conformation plot (the ratio of the logarithm of the rms radius to the logarithm of the molecular weight, where the slope of the resulting linear fit gives the degree of compactness and elongation).
[0181] Nanoparticle tracking analysis (NTA, Malvern Nanosight) can be used to determine the particle size distribution and particle concentration of the formulation. The LNP sample is appropriately diluted and injected onto a microscope slide. As the particles slowly flow through the field of view, the camera records the scattered light. Once a movie is acquired, nanoparticle tracking analysis processes the movie by tracking pixels and calculating the diffusion coefficient. This diffusion coefficient can be translated into the hydrodynamic radius of the particle. The device also gives the particle concentration by counting the number of individual particles counted during the analysis.
[0182] Cryogenic electron microscopy ("cryo-EM") can be used to determine the particle size, morphology, and structural characteristics of LNP.
[0183] The lipid composition analysis of LNP can be determined by liquid chromatography followed by charged particle detection (LC-CAD). This analysis provides a comparison of the actual lipid content with the theoretical lipid content.
[0184] The LNP formulation is analyzed for average particle size, polydispersity index (pdi), total RNA content, RNA encapsulation efficiency, and zeta potential. The LNP formulation may be further characterized by lipid analysis, AF4-MALS, NTA, and / or cryo-EM. The average particle size and polydispersity are measured by dynamic light scattering (DLS) using a Malvern Zetasizer DLS instrument. Prior to measurement by DLS, the LNP sample was diluted 30X in PBS. The Z-average diameter, which is a measure of the intensity-based average particle size, was reported along with the number average diameter and pdi. The Malvern Zetasizer instrument is also used for the measurement of the zeta potential of the LNP. Prior to measurement, the sample is diluted 1:17 (50 μL to 800 μL) in 0.1X PBS (pH 7.4).
[0185] A fluorescence-based assay (Ribogreen®, ThermoFisher Scientific) is used for the determination of total RNA concentration and free RNA. The encapsulation efficiency is calculated as (total RNA - free RNA) / total RNA. The LNP sample is appropriately diluted using 1× TE buffer containing 0.2% Triton-X 100 to determine total RNA or 1× TE buffer to determine free RNA. A standard curve is created using the starting RNA solution that was used to make the formulation and then diluted in 1× TE buffer + / - 0.2% Triton-X 100. Subsequently, the diluted RiboGreen® dye (according to the manufacturer's instructions) is added to each of the standards and samples and incubated at room temperature for approximately 10 minutes in the dark. The samples are read using a SpectraMax M5 plate reader (Molecular Devices) with the excitation, autocaloff, and emission wavelengths set at 488 nm, 515 nm, and 525 nm, respectively. The total RNA and free RNA are determined using an appropriate standard curve.
[0186] The encapsulation efficiency is calculated as (total RNA - free RNA) / total RNA. Similar methods may be used to determine the encapsulation efficiency of DNA-based or nucleic acid-containing cargo components. Oligreen Dye may be used for single-stranded DNA, and Picogreen Dye may be used for double-stranded DNA.
[0187] Use AF4-MALS to examine the molecular weight, particle size distribution, and secondary statistics based on their calculated values. Appropriately dilute the LNPs and inject them into the AF4 separation channel using the HPLC autosampler in which they are collected, and then elute them with an exponential gradient in the cross-flow across the channel. All fluids are driven by an HPLC pump and a Wyatt Eclipse device. The particles elute from the channel flow of AF4 and pass through a UV detector, a multi-angle light scattering detector, a quasi-elastic light scattering detector, and a differential refractive index detector. Use the Debeye model to process the raw data and determine the molecular weight and rms radius from the detector signals.
[0188] Quantitatively analyze the lipid components in the LNP by HPLC connected to a charged aerosol detector (CAD). Separation of the four lipid components by chromatography was achieved by reverse-phase HPLC. CAD is a mass-based detector that detects non-volatile compounds without leakage, and the signal is constant regardless of the structure of the analyte.
[0189] Cargo of Cas9 mRNA and gRNA Cas9 mRNA cargo was prepared by in vitro transcription. Capped and polyadenylated Cas9 mRNA containing 1X NLS (SEQ ID NO: 48) was generated by in vitro transcription using linearized plasmid DNA template and T7 RNA polymerase. XbaI was used at 37 °C for 2 hours under the conditions of the following 200 ng / μL plasmid, 2 U / μL XbaI (NEB), and 1× reaction buffer to linearize the plasmid DNA containing the T7 promoter and 100 nt poly(A / T) region. The reaction was heated at 65 °C for 20 minutes to inactivate XbaI. The linearized plasmid was purified from enzymes and buffer salts using a silica maxi spin column (Epoch Life Sciences), analyzed by agarose gel, and linearization was confirmed. The IVT reaction for generating Cas9 modified mRNA was incubated at 37 °C for 4 hours under the following conditions: 50 ng / μL linearized plasmid; 2 mM each of GTP, ATP, CTP, and N1-methyl pseudo-UTP (Trilink); 10 mM ARCA (Trilink); 5 U / μL T7 RNA polymerase (NEB); 1 U / μL mouse RNase inhibitor (NEB); 0.004 U / μL E. coli inorganic pyrophosphatase (NEB); and 1× reaction buffer. After 4 hours of incubation, TURBO DNase (ThermoFisher) was added to a final concentration of 0.01 U / μL and the reaction was incubated for an additional 30 minutes to remove the DNA template. Cas9 mRNA was purified from enzymes and nucleotides using the MegaClear Transcription Clean-up kit according to the manufacturer's (ThermoFisher) protocol. Alternatively, Cas9 mRNA was purified by LiCl precipitation method.
[0190] The sgRNA in this example was chemically synthesized and supplied by a commercial vendor. The sg282 sequence is described below, and the 2'-O-methyl modification and phosphorothioate bond are represented as follows (m = 2'-OMe; *= phosphorothioate): mU*mU*mA*CAGCCACGUCUACAGCAGUUUUAGAmGmCmUmAmGmAmAmAmUmAmGmCAAGUUAAAAUAAGGCUAGUCCGUUAUCAmAmCmUmUmGmAmAmAmAmAmGmUmGmGmCmAmCmCmGmAmGmUmCmGmGmUmGmCmU*mU*mU*mU. (SEQ ID NO: 42).
[0191] LNP The final LNP was characterized, and the encapsulation efficiency, polydispersity index, and average particle size were determined according to the above analysis methods.
[0192] LNP was administered to mice (single dose at 1 mg / kg or 0.5 mg / kg), and genomic DNA was isolated and subjected to the following NGS analysis.
[0193] In vivo LNP delivery In each experiment, female CD-1 mice aged 6 to 10 weeks were used. The body weights of the animals were measured, and they were divided into groups according to their body weights, and the dosing solutions were prepared based on the average body weight of the groups. LNP was administered via the lateral tail vein at a volume of 0.2 mL per animal (approximately 10 mL per kilogram of body weight). Approximately 6 hours after administration, the animals were observed for adverse effects. The body weights were measured 24 hours after administration, and at various time points, the animals were euthanized by exsanguination via cardiac puncture under isoflurane anesthesia. Blood was collected into tubes containing serum separator or sodium citrate buffer tubes for plasma as described herein. For the tests to perform in vivo editing, liver tissue was collected from the middle lobe or three independent lobes (e.g., right middle lobe, left middle lobe, and left lobe) of each animal and subjected to DNA extraction and analysis.
[0194] Mouse cohorts were measured for liver editing by next-generation sequencing (NGS) and serum TTR levels (data not shown).
[0195] Transthyretin (TTR) ELISA analysis Blood was collected and serum was isolated as shown. Mouse prealbumin (transthyretin) ELISA kit (Aviva Systems Biology, catalog OKIA00111) was used to determine the total TTR levels in mouse serum. A rat-specific ELISA kit (Aviva Systems Biology, catalog number OKIA00159) was used according to the manufacturer's protocol to measure rat serum TTR levels. Briefly, the serum was serially diluted with the kit's sample diluent to a final dilution of 10,000-fold. Then, this diluted sample was added to an ELISA plate and the assay was performed according to the instructions.
[0196] NGS sequencing Briefly, to quantitatively determine the editing efficiency at the target locus in the genome, genomic DNA was isolated and deep sequencing was utilized to identify the presence of insertions and deletions introduced by gene editing.
[0197] PCR primers were designed around the target site (e.g., TTR) to amplify the genomic region of interest. The primer sequences are provided below. Further PCR was performed according to the manufacturer's protocol (Illumina), and the chemistry required for sequencing was added. Sequencing of the amplicons was performed on an Illumina MiSeq instrument. After removing those with low quality scores, the reads were aligned against the human reference genome (e.g., hg38). The resulting file containing the reads was mapped against the reference genome (BAM file), where reads overlapping the target region of interest were selected, and the ratio of the number of wild-type reads to the number of reads containing insertions, substitutions, or deletions was calculated.
[0198] The editing ratio (e.g., "editing efficiency" or "editing rate") is defined as the total number of sequence reads containing insertions or deletions relative to the total number of sequence reads such as wild-type.
[0199] Figure 1 shows the editing ratio in mouse liver measured by NGS. As shown in Figure 1A, when 1 mg of RNA per kg was administered, the in vivo editing ratio was more than about 20% - 60% in the liver. In Figure 1B where 0.5 mg per kg was administered, editing in about 10% - 60% of the liver was observed. In this in vivo test in mice, Cas9 mRNA and gRNA were effectively delivered to hepatocytes in all compositions, and active CRISPR / Cas nuclease activity at the target site, measured by NGS of each LNP composition, was observed. The LNP containing 5% PEG lipid had a low encapsulation rate (not shown in the data figure) and somewhat lower efficacy.
[0200] Example 2 - LNP Composition Analysis Method Characterization of the LNP showed improved physicochemical parameters in the LNP formulated with increased amounts of lipid A and PEG lipid. Compositions containing 2 mol% or 3 mol% of PEG lipid (PEG2k - DMG) are listed in Table 3 below. [Table 3]
[0201] LNP Formulation - Cross - Flow Lipid-containing ethanol was mixed with 2 volumes of RNA solution and 1 volume of water by impinging jet mixing to form LNP. The lipid-containing ethanol was mixed with 2 volumes of RNA solution through a mixing intersection. A fourth stream of water was mixed with the outlet stream of the intersection through an in-line T-junction. (See Figure 2 of WO2016010840). The LNP was maintained at room temperature for 1 hour and then further diluted with water (about 1:1 v / v). The diluted LNP was concentrated using tangential flow filtration with a flat sheet cartridge (Sartorius, 100 kD MWCO), and then the buffer was exchanged to 50 mM Tris, 45 mM NaCl, 5% (w / v) sucrose, pH 7.5 (TSS) by hemodiafiltration. Alternatively, the final buffer exchange to TSS was completed with a PD-10 desalting column (GE). If necessary, the formulation was concentrated by centrifugation using an Amicon 100 kDa centrifugal filter (Millipore). The resulting mixture was then filtered using a 0.2 μm sterile filter. The final LNP was stored at 4 °C or -80 °C until further use.
[0202] Cas9 mRNA and sgRNA were prepared as described in Example 1, except that the capped and polyadenylated Cas9 U-depleted (Cas9 Udep) mRNA contains SEQ ID NO: 43. Sg282 was described in Example 1, and the sequence of sg534 ("G534") is described below: mA*mC*mG*CAAAUAUCAGUCCAGCGGUUUUAGAmGmCmUmAmGmAmAmAmUmAmGmCAAGUUAAAAUAAGGCUAGUCCGUUAUCAmAmCmUmUmGmAmAmAmAmAmGmUmGmGmCmAmCmCmGmAmGmUmCmGmGmUmGmCmU*mU*mU*mU (SEQ ID NO: 72)
[0203] The LNP formulation was analyzed for average particle size, polydispersity (pdi), total RNA content, and RNA encapsulation efficiency as described in Example 1.
[0204] Analysis of the average particle size, polydispersity index (PDI), total RNA content, and RNA encapsulation efficiency is shown in Table 4. In addition to the theoretical lipid concentration of the LNP composition, lipid analysis showed the actual molar % levels of the lipids as shown in Table 5 below. [Table 4] [Table 5] TIFF2025084955000010.tif99155
[0205] To further analyze the physicochemical properties, LNP897, LNP898, LNP966, and LNP969 were subjected to asymmetric flow field-flow fractionation-multi-angle light scattering (AF4-MALS) analysis. The AF4-MALS instrument measures the particle size and molecular weight distribution and provides information about the particle conformation and density.
[0206] The LNPs were injected into the AF4 separation channel using the HPLC autosampler in which they were collected and then eluted with an exponential gradient in the cross-flow across the channel. All fluids were driven by HPLC pumps and a Wyatt Eclipse instrument. The particles eluted from the channel flow of AF4 and passed through a UV detector, a Wyatt Heleos II multi-angle light scattering detector, a quasi-elastic light scattering detector, and a Wyatt Optilab T-rEX differential refractive index detector. Raw data were processed with Wyatt Astra 7 software using the Debye model to determine the molecular weight and rms radius from the detector signals.
[0207] The logarithmic molar mass difference plot for the LNP is shown as Figure 2A. Briefly, the X-axis represents the molar mass (g / mol), and the Y-axis represents the differential number fraction. The logarithmic molar mass difference plot shows the distribution of different molecular weights measured for a specific formulation. This provides data on the molecular weight and the overall distribution of molecular weights in the formulation, and a better picture of the particle heterogeneity than the average molecular weight.
[0208] The heterogeneity of various LNP formulations is determined by measuring different molar mass moments and calculating the ratio of the weight-average molar mass (Mw) to the number-average molar mass (Mn) to obtain the polydispersity of Mw / Mn. The polydispersity graphs for these various formulations are shown in Figure 2B.
[0209] As shown in Figure 2A, the data indicate that the particle distribution is dense at N / P 6.0 when PEG is 3 mol% and lipid A is 50 mol% and 55 mol%. This is reflected in the dense polydispersity as shown in Figure 2B.
[0210] Example 3 - AF4 MALS Data - Further Formulations The characterization of the LNP shows improved physicochemical parameters in the LNP formulated with an increased amount of lipid A. Compositions containing either 45 mol%, 50 mol%, or 55 mol% of lipid A together with two different gRNAs are listed in Table 6 below.
Table 6
[0211] The LNP was formed as described in Example 2.
[0212] Cas9 mRNA and sgRNA were prepared as described above.
[0213] The LNP composition was characterized, and the encapsulation efficiency, polydispersity index, and average particle size were determined as described in Example 1.
[0214] Analysis of the average particle size, polydispersity index (PDI), total RNA content, and RNA encapsulation efficiency is shown in Table 7. In addition to the theoretical lipid concentration of the LNP composition, lipid analysis revealed the actual molar % levels of the lipids as shown in Table 8 below. [Table 7] TIFF2025084955000013.tif46159 [Table 8] TIFF2025084955000015.tif36156
[0215] To further analyze the physicochemical properties, LNP1021, LNP1022, LNP1023, LNP1024, and LNP1025 were subjected to asymmetric flow field-flow fractionation - multi-angle light scattering (AF4-MALS) analysis. The AF4-MALS apparatus measures the particle size and molecular weight distribution and provides information about the particle conformation and density.
[0216] AF4-MALS was performed on the LNP as described in Example 1.
[0217] A plot of the molar mass difference in logarithm for the LNP is shown as Figure 3A. Briefly, the X-axis represents the molar mass (g / mol), and the Y-axis represents the differential number fraction. The plot of the molar mass difference in logarithm shows the distribution of different molecular weights calculated for a specific formulation. This provides data on the molecular weight and the overall distribution of the molecular weight in the formulation, and a better image of the particle heterogeneity than the average molecular weight.
[0218] The average molecular weight was plotted in Figure 3B. The average molecular weight is the average of the entire distribution, but no information about the shape of the distribution is obtained. LNP1022 and LNP1025 have the same average molecular weight, but the distribution is slightly broader for LNP1022.
[0219] The heterogeneity of various LNP formulations is calculated by examining different molar mass moments and calculating the ratio of the weight-average molar mass (Mw) to the number-average molar mass (Mn) to obtain the polydispersity of Mw / Mn. The polydispersity graphs of these various formulations are shown in Figure 4A.
[0220] Furthermore, the Burchard-Stockmeyer plot of the LNP formulation is shown as Figure 4B. In the Burchard-Stockmeyer plot, the ratio of the rms radius to the hydrodynamic radius in the entire eluate of the formulation from the AF4 channel is shown. Thereby, information regarding the internal density of the lipid nanoparticles can be obtained. Figure 4B shows that in this measurement, LNP1021, LNP1022, and LNP1023 have different profiles.
[0221] In Example 4 - with increased PEG lipid, efficacy is maintained and cytokine response decreases In another test, LNP formulations containing 2 mol% or 3 mol% of PEG lipid were compared with PEG DMG lipid. Compositions containing either 2 mol% or 3 mol% of PEG DMG are listed in Table 9 below. [Table 9] TIFF2025084955000017.tif51145
[0222] LNPs were formed by the method described in Example 2.
[0223] Cas9 mRNA and sgRNA were prepared as described in Example 1, and the sequence of sg390 ("G390") is described below: mG*mC*mC*GAGUCUGGAGAGCUGCAGUUUUAGAmGmCmUmAmGmAmAmAmUmAmGmCAAGUUAAAAUAAGGCUAGUCCGUUAUCAmAmCmUmUmGmAmAmAmAmAmGmUmGmGmCmAmCmCmGmAmGmUmCmGmGmUmGmCmU*mU*mU*mU (SEQ ID NO: 69).
[0224] The LNP formulations were analyzed for average particle size, polydispersity (pdi), total RNA content, and RNA encapsulation efficiency as described in Example 1.
[0225] Analysis of average particle size, polydispersity (PDI), total RNA content, and RNA encapsulation efficiency is shown in Table 10. In addition to the theoretical lipid concentration of the LNP composition, lipid analysis showed the actual lipid mole % levels as shown in Table 11 below.

[0226] Rat serum cytokines were analyzed and evaluated for MCP-1, IL-6, TNF-alpha, and IFN-gamma using a Luminex magnetic bead multiplex assay (Milliplex MAP magnetic bead assay, manufactured by Millipore Sigma, catalog number RECYTMAG-65K). The assay beads were read on a BioRad BioPlex-200, and cytokine concentrations were calculated from the standard curve using a 4-parameter logistic fit with BioPlex Manager software version 6.1. The data are graphed in Figure 5. See Figure 5A (serum TTR), Figure 5B (editing in the liver), and Figure 5C (cytokine pMCP1).
[0227] A rat-specific ELISA kit (Aviva Systems Biology, catalog number OKIA00159) was used according to the manufacturer's protocol to measure rat serum TTR levels. Briefly, serum was serially diluted with the kit's sample diluent to a final dilution of 10,000-fold. This diluted sample was then added to an ELISA plate, and the assay was performed according to the instructions.
[0228] Genomic DNA was isolated from approximately 10 mg of liver tissue and analyzed using NGS as described above. The PCR primer sequences for amplification are listed below.
[0229] Figures 5A and 5B show that serum TTR knockdown and editing in the liver were sufficient in each formulation with 2 mol% and 3 mol% PEG. Figure 5C shows that the MCP-1 response was decreased when the formulation with 3 mol% PEG was used.
[0230] Example 5 - LNP Delivery to Non-Human Primates Three tests were conducted using the LNP formulation prepared as described in Example 1. The specific molar amounts and cargos are listed in Tables 12 to 26. Each formulation containing Cas9 mRNA and guide RNA (gRNA) had an mRNA:gRNA ratio of 1:1 by weight. The LNP dosage (unit: mg / kg, total RNA content), administration route, and the presence or absence of pretreatment with dexamethasone in the animals are shown in the table. For animals pretreated with dexamethasone (Dex), Dex was administered by IV bolus injection at 2 mg / kg 1 hour before the administration of LNP or vehicle.
[0231] For blood chemical analysis, blood was collected from the animals at the times shown in the following table for each factor measured. Cytokine induction was measured in NHPs before and after treatment. A minimum of 0.5 mL of whole blood was collected from the peripheral vein of the restrained awake animal into a tube containing 4 mL of serum separator. The blood was allowed to clot at room temperature for at least 30 minutes and then centrifuged at 2000 x g for 15 minutes. The serum was dispensed into two 120 μL polypropylene microtubes and stored at -60 to -86 °C until analysis. Analysis was performed using a non-human primate U-Plex Cytokine custom kit manufactured by Meso Scale Discovery (MSD). Focusing on IL-6 and MCP-1, the following parameters, namely INF-γ, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12p40, MCP-1 and TNF-α, were included in the analysis. The kit reagents and standards were prepared as instructed in the manufacturer's operating procedure. NHP serum was used as is. The plate was read using an MSD Sector Imager 6000 and the analysis was performed using MSD Discovery Workbench software version 4012.
[0232] Complement levels were measured by enzyme immunoassay in animals before and after treatment. Whole blood (0.5 mL) was collected from the peripheral vein of the restrained awake animal into a tube containing 0.5 mL of 2 EDTA. The blood was centrifuged at 2000 x g for 15 minutes. The plasma was dispensed into two 120 μL polypropylene microtubes and stored at -60 to -86 °C until analysis. Analysis was performed using a Quidel MicroVue Complement Plus EIA kit (C3a - catalog number A031) or (Bb - catalog number A027). The kit reagents and standards were prepared as instructed in the manufacturer's operating procedure. The optical density was set to 450 nm and the plate was read using an MSD Sector Imager 6000. The results were analyzed using 4-parameter curve fitting.
[0233] Data on cytokine induction and complement activation are presented in the following table. "BLQ" means below the limit of quantification.

[0234] Example 6 - PEG Lipid Screening In another test, alternative PEG lipids were compared in LNP formulations containing 2 mol% or 3 mol% of PEG lipid.
[0235] Three PEG lipids were used in the test, and lipid 1 (DMG - PEG2k; Nof) is represented as follows.

Chem.
[0237] Lipid A was formulated using 2 mol% and 3 mol% of each PEG lipid. The lipid nanoparticle components were prepared by dissolving the lipid components in 100% ethanol at the above molar ratios. Briefly, the RNA cargo was prepared in 25 mM citrate, 100 mM NaCl, pH 5.0, and the concentration of the RNA cargo was adjusted to approximately 0.45 mg / mL. The LNP was formulated with a molar ratio of lipid amine to RNA phosphate (N:P) of approximately 4.5 and a ratio of mRNA to gRNA of 1:1 by weight.
Table 27
[0238] Cas9 mRNA, sg282, and LNP were prepared as described in Example 1.
[0239] An LNP composition containing lipid 1, lipid 2, or lipid 3 was administered to female CD-1 mice and evaluated at 1 mg / kg body weight and 0.5 mg / kg body weight as described in Example 1. Mouse cohorts were measured for liver editing by next-generation sequencing (NGS) and serum TTR levels according to the method of Example 1.
[0240] In Figures 6A and 6B, serum TTR levels are compared between PEG lipid formulations. Figure 6A shows serum TTR in μg / mL units, and Figure 6B shows data as the percentage of knockdown (TSS%). Figure 6C shows the editing rate achieved in the liver. The data indicate that LNP compositions containing each of the test PEG lipids show efficacy at 2 mol% and 3 mol%, and lipid 1 consistently performs better than lipid 2 and lipid 3.
[0241] Example 7 - Lipid A Analog A number of structural analogs of lipid A were synthesized and tested in the LNP compositions described herein.
[0242] Synthesis: Lipid A is made by reacting 4,4-bis(octyloxy)butanoic acid (“Intermediate 13b” in Example 13 of WO2015 / 095340) with (9Z,12Z)-3-hydroxy-2-(hydroxymethyl)propyl octadeca-9,12-dienoate (“Intermediate 13c”), and then reacting the product of Intermediate 13b and Intermediate 13c with 3-diethylamino-1-propanol to add a head group. (See pages 84-86 of WO2015 / 095340).
[0243] Intermediate 13b (4,4-bis(octyloxy)butanoic acid) of WO2015 / 095340 was synthesized with 4,4-bis(octyloxy)butanenitrile as follows.
[0244] Intermediate 13a: 4,4-bis(octyloxy)butanenitrile [Chemical formula]
[0245] Pyridinium p-toluenesulfonate (748 mg, 3.0 mmol) was added to a mixture of 4,4-diethoxybutanenitrile (9.4 g, 60 mmol) and octan-1-ol (23.1 g, 178 mmol) at room temperature. The mixture was warmed to 105 °C, the reaction vessel was opened, and the mixture was stirred for 18 hours without attaching a reflux condenser while being exposed to air. Then, the reaction mixture was cooled to room temperature and purified with silica gel (gradient of hexane containing ethyl acetate 0-5%) to obtain 10.1 g (31.0 mmol) of Intermediate 13a as a clear oil. 1 H NMR (400 MHz, CDCl 3) δ 4.55 (t, J = 5.3 Hz, 1H), 3.60 (dt, J = 9.2, 6.6 Hz, 2H), 3.43 (dt, J = 9.2, 6.6 Hz, 2H), 2.42 (t, J = 7.4 Hz, 2H), 1.94 (td, J = 7.4, 5.3 Hz, 2H), 1.63 - 1.50 (m, 4H), 1.38 - 1.19 (m, 20H), 0.93 - 0.82 (m, 6H) ppm。
[0246] Next, 31 mL of aqueous potassium hydroxide (2.5 M, 30.9 mL, 77.3 mmol) was added to an ethanol solution (30 mL) of intermediate 13a (8.42 g, 31 mmol) at room temperature. When a reflux condenser was attached to the reaction vessel, the mixture was heated to 110 °C and stirred for 24 hours. Thereafter, the mixture was cooled to room temperature, acidified with aqueous hydrochloric acid (1 N) to pH 5, and extracted three times into hexane. The combined organic extracts were washed with water (twice) and brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to obtain 8.15 g (23.6 mmol) of intermediate 13b as a clear oil, which was used without further purification. 1 H NMR (400 MHz, CDCl 3 ) δ 4.50 (t, J = 5.5 Hz, 1H), 3.57 (dt, J = 9.4, 6.7 Hz, 2H), 3.41 (dt, J = 9.3, 6.7 Hz, 2H), 2.40 (t, J = 7.4 Hz, 2H), 1.92 (td, J = 7.4, 5.3 Hz, 2H), 1.56 (m, 4H), 1.37 - 1.21 (m, 20H), 0.92 - 0.83 (m, 6H) ppm (the following structure).

[0259] The acetal analog of lipid A (C(8)) was synthesized by reacting a C(5, 6, 7, 9, or 10)-acetal acidic intermediate (B3 - F3) with intermediate 13c and then reacting the product of that step with 3-diethylamino-1-propanol. (See pages 84 - 86 of WO2015 / 095340). Each analog was synthesized and 1 characterized by HNMR (data not shown).
[0260] Lipid A analogs were made at 45 mol%, DMG-PEG2k at 2 mol%, DSPC at 9 mol%, and cholesterol at 44 mol%, and the C7, C9, and C10 analogs were formulated at an N:P ratio of 4.5. Each analog was also formulated at an N:P ratio of 6 with lipid A analogs at 55 mol%, DMG-PEG2k at 2.5 mol%, DSPC at 9 mol%, and cholesterol at 38.5 mol%. The lipid nanoparticle components were dissolved in 100% ethanol at the above molar ratios of the lipid components. The RNA cargo was prepared in 25 mM citrate, 100 mM NaCl, pH 5.0, and the concentration of the RNA cargo was set at approximately 0.45 mg / mL.
[0261] The RNA cargo included Cas9 mRNA containing SEQ ID NO: 43 and sg282 and was prepared as described above. LNPs were formed as described in Example 1.
[0262] An extended panel of acetal analogs, including LNP compositions containing C(5) and C(6) lipid A analogs, was tested with the previous panel. Two new analogs were formulated as described above at an N / P ratio of 6 with 55 mol% lipid A analog, 2.5 mol% DMG-PEG2k, 9 mol% DPSC, and 33.5 mol% cholesterol. Analysis showed that all LNPs were below 120 nm in size, had a PDI of less than 0.2, and a percentage of encapsulated RNA greater than 80%. The analysis results of the formulations are presented in Table 28 below.

[0263] 6-(p-Toluidino)-6-naphthalenesulfonic acid ("TNS") dissolved in water was used to evaluate the analogs for pKa. In this assay, 0.1 M phosphate buffer was prepared at different pH values in the range of 4.5 - 10.5. Each analog was individually prepared in 100% ethanol. Lipids and TNS were then added to the individual pH buffers and transferred to plates and analyzed at wavelengths of 321 - 488 nm using a SpectraMax microplate reader. Values were plotted to generate the pKa. The logarithm of the IC 50 was used as the pKa.
[0264] Female CD-1 mice were administered 0.3 mg / kg (Figs. 7A-7E) or 0.1 mg per kg (Figs. 7F-7G) as described in Example 1. Briefly, female CD-1 mice obtained from Charles River Laboratories (n = 5 / group) were administered the LNP composition at various doses. At necropsy (7 days after administration), serum was collected for TTR analysis and liver was collected for editing analysis. Serum TTR assay and editing rate assay were performed as described in Example 1. For the serum TTR levels and editing in the liver in Figs. 7A to 7E, all analogs are shown to have performance comparable to that of Lipid A at 0.3 milligrams per kilogram of body weight. In Figs. 7F - 7G, Lipid A was the most potent, but all newly synthesized analogs are shown to have appropriate TTR knockdown and editing in the liver.
[0265] Example 8 - Dose - response curve - Primary Cyno hepatocytes Primary hepatocytes of the liver. Primary cynomolgus monkey liver hepatocytes (PCH) (Gibco) were thawed and resuspended in hepatocyte thawing medium containing additives (Gibco, catalog CM7000), and then centrifuged at 80 g for 4 minutes. The supernatant was discarded, and the pelleted cells were resuspended in hepatocyte seeding medium pack containing additives (Invitrogen, catalog A1217601 and CM3000). The cells were counted and seeded at a density of 50,000 cells / well in a Bio - coat collagen I - coated 96 - well plate (ThermoFisher, catalog 877272). The seeded cells were allowed to settle and placed in a tissue culture incubator (37 °C, 5% CO 2 atmosphere) for 24 hours to adhere, and then the LNP was administered. After incubation, the cells were checked for monolayer formation and the medium was replaced with hepatocyte medium and a serum - free additive pack (Invitrogen, catalog A1217601 and CM4000).
[0266] The LNP formulations for this study (LNP1021, LNP1022, LNP1023, LNP1024, LNP1025, and LNP897) were prepared as described above.
[0267] Lipid nanoparticle formulations containing modified sgRNA were tested at various doses in cynomolgus monkey primary hepatocytes, and a dose-response curve was generated. After seeding and culturing for 24 hours, the LNP was incubated with hepatocyte maintenance medium containing 6% cynomolgus monkey serum at 37 °C for 5 minutes. After incubation, the LNP was added to cynomolgus monkey primary hepatocytes starting with 100 ng of mRNA with an 8.2-fold dose-response curve. Cells were lysed 72 hours after treatment, and NGS analysis was performed as described in Example 1. Data determining the editing rate for various LNP compositions are graphed in Figure 8A. The editing rates (%) with Cas9 mRNA (SEQ ID NO: 48) and U-removed Cas9 mRNA (SEQ ID NO: 43) are described in Figure 8B. The LNP compositions are described in Table 2 (LNP897) and Table 5 (LNP1021, LNP1022, LNP1023, LNP1024, and LNP1025).
[0268] The results show a quantitative assessment of comparative efficacy, indicating that both the mRNA and the LNP composition affect efficacy.
[0269] Example 9 - RNA Cargo: mRNA and gRNA Cocktails In this study, the in vivo efficacy in mice was evaluated when the ratio of gRNA to mRNA was different. CleanCap™-capped Cas9 mRNA having the ORF of SEQ ID NO: 4, HSD 5'UTR, human albumin 3'UTR, Kozak sequence, and polyA tail was prepared by IVT synthesis using N1-methylpseudouridine triphosphate instead of uridine triphosphate as shown in Example 1.
[0270] The LNP formulation was prepared as described in Example 2 from the described mRNA and sg282 (SEQ ID NO: 42; G282) with a molar ratio of lipid A, cholesterol, DSPC, and PEG2k-DMG of 50:38:9:3 and an N:P ratio of 6. The gRNA:Cas9 mRNA weight ratio of the formulation was as shown in Table 29.
Table 29
[0271] For in vivo characterization, the above LNPs were administered to mice at a total RNA (guide RNA (mg) + mRNA (mg)) of 0.1 mg per kg (n = 5 / group). On days 7 to 9 after administration, the animals were sacrificed and blood and liver were collected, and serum TTR and editing in the liver were measured as described in Example 1. The results of serum TTR and liver editing are shown in FIGS. 9A and 9B. The negative control mice were administered the TSS vehicle.
[0272] Furthermore, the above LNPs were administered to mice, and at that time, the mRNA was set at a fixed dose of 0.05 mg of mRNA per kg (n = 5 / group), and the dose of gRNA was changed from 0.06 mg per kg to 0.4 mg per kg. On days 7 to 9 after administration, the animals were sacrificed and blood and liver were collected, and serum TTR and editing in the liver were measured. The results of serum TTR and liver editing are shown in FIGS. 9C and 9D. The negative control mice were administered the TSS vehicle.
[0273] Example 10-Neutral Lipid To evaluate the in vivo efficacy of the LNP, an LNP formulation was prepared as described in Example 2 using the mRNA of Example 2 and sg534 (SEQ ID NO: 72; G534). The lipid nanoparticle components were dissolved in 100% ethanol at the following lipid component molar ratios. Briefly, an RNA cargo was prepared in a buffer of 25 mM citrate and 100 mM NaCl (pH 5.0), and the concentration of the RNA cargo was adjusted to approximately 0.45 mg / mL. The LNP was formulated with a molar ratio of lipid amine to RNA phosphate (N:P) of approximately 6 and a ratio of mRNA to gRNA of 1:2 by weight.
[0274] The LNP formulations were analyzed for average particle size, polydispersity (pdi), total RNA content, and RNA encapsulation efficiency as described in Example 1. The analysis of average particle size, polydispersity (PDI), total RNA content, and RNA encapsulation efficiency is shown in Table 30. The molar ratio of lipids is described as amine lipid (lipid A) / neutral lipid / helper lipid (cholesterol) / PEG lipid (PEG2k-DMG). The neutral lipid was DSP, DPPC, or absent as indicated.
Table 30
[0275] For in vivo characterization, female Sprague Dawley rats were intravenously administered the above LNP with 0.3 mg total RNA (guide RNA and mRNA) per kg body weight. The rats were 5 per group. On day 7 after administration, the animals were sacrificed and blood and liver were collected, and serum TTR and editing in the liver were measured as described in Example 1. The TSS vehicle was administered to negative control animals. The results of serum TTR and editing in the liver are shown in Figures 10A and 10B, and Table 30 (above).

[0276] For the array itself, refer to the following Sequence Listing. In general, the transcript array contains GGG as the first 3 nucleotides for use with ARCA, or AGG as the first 3 nucleotides for use with CleanCap™. Thus, the first 3 nucleotides can be modified for use with other capping methods, such as the vaccinia capping enzyme. The promoter and polyA sequences are not included in the transcript array. Promoters such as the T7 promoter (SEQ ID NO: 31) and polyA sequences such as SEQ ID NO: 62 or 63 can be added to the disclosed transcript array at the 5' and 3' ends, respectively. Most nucleotide sequences are provided as DNA, but they can be easily converted to RNA by changing T to U.
[0277] Sequence Listing The following Sequence Listing provides a list of the sequences disclosed herein. It is understood that when a DNA sequence (including T) is referred to in relation to RNA, T must be replaced by U (either modified or unmodified depending on the situation), and vice versa.
