Muscular dystrophies (MD) are a group of more than 30 genetic diseases characterized by progressive weakness and degeneration of the skeletal muscles that control movement. Duchenne muscular dystrophy (DMD) is one of the most severe forms of MD that affects approximately 1 in 5000 boys and is characterized by progressive muscle weakness and premature death. Cardiomyopathy and heart failure are common, incurable and lethal features of DMD. The disease is caused by mutations in the gene encoding dystrophin (DMD), which result in loss of expression of dystrophin, causing muscle membrane fragility and progressive muscle wasting.
CRISPR-based genome editing can provide sequence-specific cleavage of genomic DNA using a Cas9 and a guide RNA. For example, a nucleic acid encoding the Cas9 enzyme and a nucleic acid encoding for the appropriate guide RNA can be provided on separate vectors or together on a single vector and administered in vivo or in vitro to knockout or correct a genetic mutation, for example. The approximately 20 nucleotides at the 5′ end of the guide RNA serves as the guide or spacer sequence that can be any sequence complementary to one strand of a genomic target location that has an adjacent protospacer adjacent motif (PAM). The PAM sequence is a short sequence adjacent to the Cas9 nuclease cut site that the Cas9 molecule requires for appropriate binding. The nucleotides 3′ of the guide or spacer sequence of the guide RNA serve as a scaffold sequence for interacting with Cas9. When a guide RNA and a Cas9 are expressed, the guide RNA will bind to Cas9 and direct it to the sequence complementary to the guide sequence, where it will then initiate a double-stranded break (DSB). To repair these breaks, cells typically use an error prone mechanism of non-homologous end joining (NHEJ) which can lead to disruption of function in the target gene through insertions or deletion of codons, shifts in the reading frame, or result in a premature stop codon triggering nonsense-mediated decay. See, e.g., Kumar et al. (2018) Front. Mol. Neurosci. Vol. 11, Article 413.
While gene editing strategies using systems (e.g., CRISPR) for treating DMD have been previously explored, these strategies have focused primarily on either: a) cutting at multiple different sites to excise large portions (e.g., one or more exons) ofthe dystrophin gene (see, e.g., Ousterout et al., 2015, Nat Commun. 6:6244); or b) cutting in a single site to introduce indels that either result in a frame-shifting mutation and/or that destroy a splice acceptor/donor site in the dystrophin gene (see, e.g., Amoassi et al., 2018, Science, 362(6410):86-91). However, there remains a need for additional alternative and effective gene editing strategies for treating diseases like DMD.
Provided herein are compositions and methods for treating DMD utilizing Cas proteins such as Staphylococcus aureus (SaCas9) and Staphylococcus lugdunensis (SluCas9). In some embodiments, pairs of guide RNAs that excise small portions of the DMD gene are provided, where the nucleic acid encoding the pairs of guide RNAs may be on a single nucleic acid molecule.

Unless stated otherwise, the following terms and phrases as used herein are intended to have the following meanings:
“Polynucleotide,” “nucleic acid,” and “nucleic acid molecule,” are used herein to refer to a multimeric compound comprising nucleosides or nucleoside analogs which have nitrogenous heterocyclic bases or base analogs linked together along a backbone, including conventional RNA, DNA, mixed RNA-DNA, and polymers that are analogs thereof. A nucleic acid “backbone” can be made up of a variety of linkages, including one or more of sugar-phosphodiester linkages, peptide-nucleic acid bonds (“peptide nucleic acids” or PNA; PCT No. WO 95/32305), phosphorothioate linkages, methylphosphonate linkages, or combinations thereof. Sugar moieties of a nucleic acid can be ribose, deoxyribose, or similar compounds with substitutions, e.g., 2′ methoxy or 2′ halide substitutions. Nitrogenous bases can be conventional bases (A, G, C, T, U), analogs thereof (e.g., modified uridines such as 5-methoxyuridine, pseudouridine, or N1-methylpseudouridine, or others); inosine; derivatives of purines or pyrimidines (e.g., N4-methyl deoxyguanosine, deaza- or aza-purines, deaza- or aza-pyrimidines, pyrimidine bases with substituent groups at the 5 or 6 position (e.g., 5-methylcytosine), purine bases with a substituent at the 2, 6, or 8 positions, 2-amino-6-methylaminopurine, O6-methylguanine, 4-thio-pyrimidines, 4-amino-pyrimidines, 4-dimethylhydrazine-pyrimidines, and O4-alkyl-pyrimidines; U.S. Pat. No. 5,378,825 and PCT No. WO 93/13121). For general discussion see The Biochemistry of the Nucleic Acids 5-36, Adams et al., ed., 11th ed., 1992). Nucleic acids can include one or more “abasic” residues where the backbone includes no nitrogenous base for position(s) of the polymer (U.S. Pat. No. 5,585,481). A nucleic acid can comprise only conventional RNA or DNA sugars, bases and linkages, or can include both conventional components and substitutions (e.g., conventional bases with 2′ methoxy linkages, or polymers containing both conventional bases and one or more base analogs). Nucleic acid includes “locked nucleic acid” (LNA), an analogue containing one or more LNA nucleotide monomers with a bicyclic furanose unit locked in an RNA mimicking sugar conformation, which enhance hybridization affinity toward complementary RNA and DNA sequences (Vester and Wengel, 2004, Biochemistry 43(42):13233-41). RNA and DNA have different sugar moieties and can differ by the presence of uracil or analogs thereof in RNA and thymine or analogs thereof in DNA.
“Guide RNA”, and simply “guide” are used herein interchangeably to refer to either a crRNA (also known as CRISPR RNA), or the combination of a crRNA and a trRNA (also known as tracrRNA). The crRNA and trRNA may be associated as a single RNA molecule (single guide RNA, sgRNA) or in two separate RNA molecules (dual guide RNA, dgRNA). “Guide RNA” refers to each type. The trRNA may be a naturally-occurring sequence, or a trRNA sequence with modifications or variations compared to naturally-occurring sequences. For clarity, the terms “guide RNA” or “guide” as used herein, and unless specifically stated otherwise, may refer to an RNA molecule (comprising A, C, G, and U nucleotides) or to a DNA molecule encoding such an RNA molecule (comprising A, C, G, and T nucleotides) or complementary sequences thereof. In general, in the case of a DNA nucleic acid construct encoding a guide RNA, the U residues in any of the RNA sequences described herein may be replaced with T residues, and in the case of a guide RNA construct encoded by any of the DNA sequences described herein, the T residues may be replaced with U residues.
As used herein, a “spacer sequence,” sometimes also referred to herein and in the literature as a “spacer,” “protospacer,” “guide sequence,” or “targeting sequence” refers to a sequence within a guide RNA that is complementary to a target sequence and functions to direct a guide RNA to a target sequence for cleavage by a Cas9. For clarity, the terms “spacer sequence”, “spacer,” “protospacer,” “guide sequence,” or “targeting sequence” as used herein, and unless specifically stated otherwise, may refer to an RNA molecule (comprising A, C, G, and U nucleotides) or to a DNA molecule encoding such an RNA molecule (comprising A, C, G, and T nucleotides) or complementary sequences thereof. A guide sequence can be 24, 23, 22, 21, 20 or fewer base pairs in length, e.g., in the case of Staphylococcus lugdunensis (i.e., SluCas9) or Staphylococcus aureus (i.e., SaCas9) and related Cas9 homologs/orthologs. In preferred embodiments, a guide/spacer sequence in the case of SluCas9 or SaCas9 is at least 20 base pairs in length, or more specifically, within 20-25 base pairs in length (see, e.g., Schmidt et al., 2021, Nature Communications, “Improved CRISPR genome editing using small highly active and specific engineered RNA-guided nucleases”). Shorter or longer sequences can also be used as guides, e.g., 15-, 16-, 17-, 18-, 19-, 20-, 21-, 22-, 23-, 24-, or 25-nucleotides in length. For example, in some embodiments, the guide sequence comprises at least 17, 18, 19, 20, 21, 22, 23, 24, or 25 contiguous nucleotides of a sequence selected from SEQ ID NOs: 11-15 or 27-69 (for SaCas9, including SaCas9KKH), and 243-269 (for SluCas9). In preferred embodiments, a guide/spacer sequence in the case of SluCas9 or SaCas9 is at least 20 base pairs in length, or more specifically, within 20-25 base pairs in length (see, e.g., Schmidt et al., 2021, Nature Communications, “Improved CRISPR genome editing using small highly active and specific engineered RNA-guided nucleases”). In some embodiments, the guide sequence comprises a sequence selected from SEQ ID NOs: 11-15, 27-69, or 243-269. In some embodiments, the target sequence is in a gene or on a chromosome, for example, and is complementary to the guide sequence. In some embodiments, the degree of complementarity or identity between a guide sequence and its corresponding target sequence may be about 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100%. For example, in some embodiments, the guide sequence comprises a sequence with about 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100% identity to at least 17, 18, 19, 20, 21, 22, 23, 24, or 25 contiguous nucleotides of a sequence selected from SEQ ID NOs: 11-15, 27-69, or 243-269. In some embodiments, the guide sequence comprises a sequence with about 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100% identity to a sequence selected from SEQ ID NOs: 11-15, 27-69, or 243-269. 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, where the total 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 1-4 mismatches where the guide sequence comprises 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 where the guide sequence comprises 20 nucleotides. In some embodiments, the guide sequence and the target region do not contain any mismatches.
In some embodiments, the guide sequence comprises a sequence selected from SEQ ID NOs: 11-15, 27-69, or 243-269, wherein if the 5′ terminal nucleotide is not guanine, one or more guanine (g) is added to the sequence at its 5′ end. In some embodiments, the 5′ g or gg is included in some instances for transcription, for example, for expression by the RNA polymerase III-dependent U6 promoter or the T7 promoter. In some embodiments, a 5′ guanine is added to any one of the guide sequences or pairs of guide sequences disclosed herein.
Target sequences for Cas9s include both the positive and negative strands of genomic DNA (i.e., the sequence given and the sequence's reverse compliment), as a nucleic acid substrate for a Cas9 is a double stranded nucleic acid. Accordingly, where a guide sequence is said to be “complementary to a target sequence”, it is to be understood that the guide sequence may direct a guide RNA to bind to the reverse complement of a target sequence. Thus, in some embodiments, where the guide sequence binds the reverse complement of a target sequence, the guide sequence is identical to certain nucleotides of the target sequence (e.g., the target sequence not including the PAM) except for the substitution of U for T in the guide sequence.
As used herein, “ribonucleoprotein” (RNP) or “RNP complex” refers to a guide RNA together with a Cas9. In some embodiments, the guide RNA guides the Cas9, such as a SluCas9 or a SaCas9, to a target sequence, and the guide RNA hybridizes with and the agent binds to the target sequence, which can be followed by cleaving or nicking (in the context of a modified “nickase” Cas9).
As used herein, a first sequence is considered to “comprise a sequence with at least X % identity to” a second sequence if an alignment of the first sequence to the second sequence shows that X % or more of the positions of the second sequence in its entirety are matched by the first sequence. For example, the sequence AAGA comprises a sequence with 100% identity to the sequence AAG because an alignment would give 100% identity in that there are matches to all three positions of the second sequence. 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 uridines do not contribute to differences in identity or complementarity among polynucleotides as long as the relevant nucleotides (such as thymidine, uridine, or modified uridine) have the same complement (e.g., adenosine for all of thymidine, uridine, or modified uridine; another example is cytosine and 5-methylcytosine, both of which have guanosine or modified guanosine as a complement). Thus, for example, the sequence 5′-AXG where X is any modified uridine, such as pseudouridine, N1-methyl pseudouridine, or 5-methoxyuridine, is considered 100% identical to AUG in that both are perfectly 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. One skilled in the art will understand what choice of algorithm and parameter settings are appropriate for a given pair of sequences to be aligned; for sequences of generally similar length and expected identity >50% for amino acids or >75% for nucleotides, the Needleman-Wunsch algorithm with default settings of the Needleman-Wunsch algorithm interface provided by the EBI at the www.ebi.ac.uk web server is generally appropriate.
“mRNA” is used herein to refer to a polynucleotide that is not DNA and comprises an open reading frame that can be translated into a polypeptide (i.e., can serve as a substrate for translation by a ribosome and amino-acylated tRNAs). mRNA can comprise a phosphate-sugar backbone including ribose residues or analogs thereof, e.g., 2′-methoxy ribose residues. In some embodiments, the sugars of an mRNA phosphate-sugar backbone consist essentially of ribose residues, 2′-methoxy ribose residues, or a combination thereof.
Guide sequences useful in the guide RNA compositions and methods described herein are shown, for example, in Tables 1-2, and throughout the specification.
As used herein, a “target sequence” refers to a sequence of nucleic acid in a target gene that has complementarity to at least a portion of the guide sequence of the guide RNA. The interaction of the target sequence and the guide sequence directs a Cas9 to bind, and potentially nick or cleave (depending on the activity of the agent), within or near the target sequence.
As used herein, “treatment” refers to any administration or application of a therapeutic for disease or disorder in a subject, and includes inhibiting the disease or development of the disease (which may occur before or after the disease is formally diagnosed, e.g., in cases where a subject has a genotype that has the potential or is likely to result in development of the disease), arresting its development, relieving one or more symptoms of the disease, curing the disease, or preventing reoccurrence of one or more symptoms of the disease. For example, treatment of DMD may comprise alleviating symptoms of DMD.
As used herein, “ameliorating” refers to any beneficial effect on a phenotype or symptom, such as reducing its severity, slowing or delaying its development, arresting its development, or partially or completely reversing or eliminating it. In the case of quantitative phenotypes such as expression levels, ameliorating encompasses changing the expression level so that it is closer to the expression level seen in healthy or unaffected cells or individuals.
A “pharmaceutically acceptable excipient” refers to an agent that is included in a pharmaceutical formulation that is not the active ingredient. Pharmaceutically acceptable excipients may e.g., aid in drug delivery or support or enhance stability or bioavailability.
The term “about” or “approximately” means an acceptable error for a particular value as determined by one of ordinary skill in the art, which depends in part on how the value is measured or determined.
As used herein, “Staphylococcus aureus Cas9” may also be referred to as SaCas9, and includes wild type SaCas9 (e.g., SEQ ID NO: 711) and variants thereof. A variant of SaCas9 comprises one or more amino acid changes as compared to SEQ ID NO: 711, including insertion, deletion, or substitution of one or more amino acids, or a chemical modification to one or more amino acids. For clarity, SaCas9KKIH is a SaCas9 variant.
As used herein, “Staphylococcus lugdunensis Cas9” may also be referred to as SluCas9, and includes wild type SluCas9 (e.g., SEQ ID NO: 712) and variants thereof. A variant of SluCas9 comprises one or more amino acid changes as compared to SEQ ID NO: 712, including insertion, deletion, or substitution of one or more amino acids, or a chemical modification to one or more amino acids.

In some embodiments, the guide RNA is chemically modified. A guide RNA comprising one or more modified nucleosides or nucleotides is called a “modified” guide RNA or “chemically modified” guide RNA, to describe the presence of one or more non-naturally and/or naturally occurring components or configurations that are used instead of or in addition to the canonical A, G, C, and U residues. In some embodiments, a modified guide RNA is synthesized with a non-canonical nucleoside or nucleotide, is here called “modified.” Modified nucleosides and nucleotides can include one or more of: (i) alteration, e.g., replacement, of one or both of the non-linking phosphate oxygens and/or of one or more of the linking phosphate oxygens in the phosphodiester backbone linkage (an exemplary backbone modification); (ii) alteration, e.g., replacement, of a constituent of the ribose sugar, e.g., of the 2′ hydroxyl on the ribose sugar (an exemplary sugar modification); (iii) wholesale replacement of the phosphate moiety with “dephospho” linkers (an exemplary backbone modification); (iv) modification or replacement of a naturally occurring nucleobase, including with a non-canonical nucleobase (an exemplary base modification); (v) replacement or modification of the ribose-phosphate backbone (an exemplary backbone modification); (vi) modification of the 3′ end or 5′ end of the oligonucleotide, e.g., removal, modification or replacement of a terminal phosphate group or conjugation of a moiety, cap or linker (such 3′ or 5′ cap modifications may comprise a sugar and/or backbone modification); and (vii) modification or replacement of the sugar (an exemplary sugar modification).
Chemical modifications such as those listed above can be combined to provide modified guide RNAs comprising nucleosides and nucleotides (collectively “residues”) that can have two, three, four, or more modifications. For example, a modified residue can have a modified sugar and a modified nucleobase, or a modified sugar and a modified phosphodiester. In some embodiments, every base of a guide RNA is modified, e.g., all bases have a modified phosphate group, such as a phosphorothioate group. In certain embodiments, all, or substantially all, of the phosphate groups of a guide RNA molecule are replaced with phosphorothioate groups. In some embodiments, modified guide RNAs comprise at least one modified residue at or near the 5′ end of the RNA. In some embodiments, modified guide RNAs comprise at least one modified residue at or near the 3′ end of the RNA.
In some embodiments, the guide RNA comprises 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 in a modified guide RNA are modified nucleosides or nucleotides.
Unmodified nucleic acids can be prone to degradation by, e.g., intracellular nucleases or those found in serum. For example, nucleases can hydrolyze nucleic acid phosphodiester bonds. Accordingly, in one aspect the guide RNAs described herein can contain one or more modified nucleosides or nucleotides, e.g., to introduce stability toward intracellular or serum-based nucleases. In some embodiments, the modified guide RNA molecules described herein can exhibit a reduced innate immune response when introduced into a population of cells, both in vivo and ex vivo. The term “innate immune response” includes a cellular response to exogenous nucleic acids, including single stranded nucleic acids, which involves the induction of cytokine expression and release, particularly the interferons, and cell death.
In some embodiments of a backbone modification, the phosphate group of a modified residue can be modified by replacing one or more of the oxygens with a different substituent. Further, the modified residue, e.g., modified residue present in a modified nucleic acid, can include the wholesale replacement of an unmodified phosphate moiety with a modified phosphate group as described herein. In some embodiments, the backbone modification of the phosphate backbone can include alterations that result in either an uncharged linker or a charged linker with unsymmetrical charge distribution.
Examples of modified phosphate groups include, phosphorothioate, phosphoroselenates, borano phosphates, borano phosphate esters, hydrogen phosphonates, phosphoroamidates, alkyl or aryl phosphonates and phosphotriesters. The phosphorous atom in an unmodified phosphate group is achiral. However, replacement of one of the non-bridging oxygens with one of the above atoms or groups of atoms can render the phosphorous atom chiral. The stereogenic phosphorous atom can possess either the “R” configuration (herein Rp) or the “S” configuration (herein Sp). The backbone can also be modified by replacement of a bridging oxygen, (i.e., the oxygen that links the phosphate to the nucleoside), with nitrogen (bridged phosphoroamidates), sulfur (bridged phosphorothioates) and carbon (bridged methylenephosphonates). The replacement can occur at either linking oxygen or at both of the linking oxygens.
The phosphate group can be replaced by non-phosphorus containing connectors in certain backbone modifications. In some embodiments, the charged phosphate group can be replaced by a neutral moiety. Examples of moieties which can replace the phosphate group can include, without limitation, e.g., methyl phosphonate, hydroxylamino, siloxane, carbonate, carboxymethyl, carbamate, amide, thioether, ethylene oxide linker, sulfonate, sulfonamide, thioformacetal, formacetal, oxime, methyleneimino, methylenemethylimino, methylenehydrazo, methylenedimethylhydrazo and methyleneoxymethylimino.
Scaffolds that can mimic nucleic acids can also be constructed wherein the phosphate linker and ribose sugar are replaced by nuclease resistant nucleoside or nucleotide surrogates. Such modifications may comprise backbone and sugar modifications. In some embodiments, the nucleobases can be tethered by a surrogate backbone. Examples can include, without limitation, the morpholino, cyclobutyl, pyrrolidine and peptide nucleic acid (PNA) nucleoside surrogates.
The modified nucleosides and modified nucleotides can include one or more modifications to the sugar group, i.e. at sugar modification. For example, the 2′ hydroxyl group (OH) can be modified, e.g. replaced with a number of different “oxy” or “deoxy” substituents. In some embodiments, modifications to the 2′ hydroxyl group can enhance the stability of the nucleic acid since the hydroxyl can no longer be deprotonated to form a 2′-alkoxide ion.
Examples of 2′ hydroxyl group modifications can include alkoxy or aryloxy (OR, wherein “R” can be, e.g., alkyl, cycloalkyl, aryl, aralkyl, heteroaryl or a sugar); polyethyleneglycols (PEG), O(CH2CH2O)˜CH2CH2OR wherein R can be, e.g., H or optionally substituted alkyl, and n can be an integer from 0 to 20 (e.g., from 0 to 4, from 0 to 8, from 0 to 10, from 0 to 16, from 1 to 4, from 1 to 8, from 1 to 10, from 1 to 16, from 1 to 20, from 2 to 4, from 2 to 8, from 2 to 10, from 2 to 16, from 2 to 20, from 4 to 8, from 4 to 10, from 4 to 16, and from 4 to 20). In some embodiments, the 2′ hydroxyl group modification can be 2-O-Me. In some embodiments, the 2′ hydroxyl group modification can be a 2′-fluoro modification, which replaces the 2′ hydroxyl group with a fluoride. In some embodiments, the 2′ hydroxyl group modification can include “locked” nucleic acids (LNA) in which the 2′ hydroxyl can be connected, e.g., by a C1-6 alkylene or C1-6 heteroalkylene bridge, to the 4′ carbon of the same ribose sugar, where exemplary bridges can include methylene, propylene, ether, or amino bridges; O-amino (wherein amino can be, e.g., NH2; alkylamino, dialkylamino, heterocyclyl, arylamino, diarylamino, heteroarylamino, or diheteroarylamino, ethylenediamine, or polyamino) and aminoalkoxy, O(CH2)˜-amino, (wherein amino can be, e.g., NH2; alkylamino, dialkylamino, heterocyclyl, arylamino, diarylamino, heteroarylamino, or diheteroarylamino, ethylenediamine, or polyamino). In some embodiments, the 2′ hydroxyl group modification can include “unlocked” nucleic acids (UNA) in which the ribose ring lacks the C2′-C3′ bond. In some embodiments, the 2′ hydroxyl group modification can include the methoxyethyl group (MOE), (OCH2CH2OCH3, e.g., a PEG derivative).
“Deoxy” 2′ modifications can include hydrogen (i.e. deoxyribose sugars, e.g., at the overhang portions of partially dsRNA); halo (e.g., bromo, chloro, fluoro, or iodo); amino (wherein amino can be, e.g., NH2; alkylamino, dialkylamino, heterocyclyl, arylamino, diarylamino, heteroarylamino, diheteroarylamino, or amino acid); NH(CH2CH2NH)˜CH2CH2— amino (wherein amino can be, e.g., as described herein), —NHC(O)R (wherein R can be, e.g., alkyl, cycloalkyl, aryl, aralkyl, heteroaryl or sugar), cyano; mercapto; alkyl-thio-alkyl; thioalkoxy; and alkyl, cycloalkyl, aryl, alkenyl and alkynyl, which may be optionally substituted with e.g., an amino as described herein.
The sugar modification can comprise a sugar group which may also contain one or more carbons that possess the opposite stereochemical configuration than that of the corresponding carbon in ribose. Thus, a modified nucleic acid can include nucleotides containing e.g., arabinose, as the sugar. The modified nucleic acids can also include abasic sugars. These abasic sugars can also be further modified at one or more of the constituent sugar atoms. The modified nucleic acids can also include one or more sugars that are in the L form, e.g. L-nucleosides.
The modified nucleosides and modified nucleotides described herein, which can be incorporated into a modified nucleic acid, can include a modified base, also called a nucleobase. Examples of nucleobases include, but are not limited to, adenine (A), guanine (G), cytosine (C), and uracil (U). These nucleobases can be modified or wholly replaced to provide modified residues that can be incorporated into modified nucleic acids. The nucleobase of the nucleotide can be independently selected from a purine, a pyrimidine, a purine analog, or pyrimidine analog. In some embodiments, the nucleobase can include, for example, naturally-occurring and synthetic derivatives of a base.
In embodiments employing a dual guide RNA, each of the crRNA and the tracr RNA can contain modifications. Such modifications may be at one or both ends of the crRNA and/or tracr RNA. In embodiments comprising sgRNA, one or more residues at one or both ends of the sgRNA may be chemically modified, and/or internal nucleosides may be modified, and/or the entire sgRNA may be chemically modified. Certain embodiments comprise a 5′ end modification. Certain embodiments comprise a 3′ end modification.
Modifications of 2′-O-methyl are encompassed.
Another chemical modification that has been shown to influence nucleotide sugar rings is halogen substitution. For example, 2′-fluoro (2′-F) substitution on nucleotide sugar rings can increase oligonucleotide binding affinity and nuclease stability. Modifications of 2′-fluoro (2′-F) are encompassed.
Phosphorothioate (PS) linkage or bond refers to a bond where a sulfur is substituted for one nonbridging phosphate oxygen in a phosphodiester linkage, for example in the bonds between nucleotides bases. When phosphorothioates are used to generate oligonucleotides, the modified oligonucleotides may also be referred to as S-oligos.
Abasic nucleotides refer to those which lack nitrogenous bases.
Inverted bases refer to those with linkages that are inverted from the normal 5′ to 3′ linkage (i.e., either a 5′ to 5′ linkage or a 3′ to 3′ linkage).
An abasic nucleotide can be attached with an inverted linkage. For example, an abasic nucleotide may be attached to the terminal 5′ nucleotide via a 5′ to 5′ linkage, or an abasic nucleotide may be attached to the terminal 3′ nucleotide via a 3′ to 3′ linkage. An inverted abasic nucleotide at either the terminal 5′ or 3′ nucleotide may also be called an inverted abasic end cap.
In some embodiments, one or more of the first three, four, or five nucleotides at the 5′ terminus, and one or more of the last three, four, or five nucleotides at the 3′ terminus are modified. In some embodiments, the modification is a 2′-O-Me, 2′-F, inverted abasic nucleotide, PS bond, or other nucleotide modification well known in the art to increase stability and/or performance.
In some embodiments, the first four nucleotides at the 5′ terminus, and the last four nucleotides at the 3′ terminus are linked with phosphorothioate (PS) bonds.
In some embodiments, the first three nucleotides at the 5′ terminus, and the last three nucleotides at the 3′ terminus comprise a 2′-O-methyl (2′-O-Me) modified nucleotide. In some embodiments, the first three nucleotides at the 5′ terminus, and the last three nucleotides at the 3′ terminus comprise a 2′-fluoro (2′-F) modified nucleotide.
In some embodiments, a composition is encompassed comprising: a) one or more guide RNAs comprising one or more guide sequences from Table 2 and b) SaCas9 (when combined with a gRNA comprising any one of or combination of SEQ ID Nos: 11-15 or 27-69) or SluCas9 (when combined with a gRNA comprising any one of or combination of SEQ ID Nos: 243-269), or any of the mutant Cas9 proteins disclosed herein. In some embodiments, the guide RNA together with a Cas9 is called a ribonucleoprotein complex (RNP).
In some embodiments, the disclosure provides for an RNP complex, wherein the guide RNA (e.g., any of the guide RNAs disclosed herein) binds to or is capable of binding to a target sequence in the dystrophin gene.
In some embodiments, chimeric Cas9 (SaCas9 or SluCas9) nucleases are used, where one domain or region of the protein is replaced by a portion of a different protein. In some embodiments, a Cas9 nuclease domain may be replaced with a domain from a different nuclease such as Fok1. In some embodiments, a Cas9 nuclease may be a modified nuclease.
In some embodiments, the Cas9 is modified to contain only one functional nuclease domain. For example, the agent protein may be modified such that one of the nuclease domains is mutated or fully or partially deleted to reduce its nucleic acid cleavage activity.
In some embodiments, a conserved amino acid within a Cas9 protein nuclease domain is substituted to reduce or alter nuclease activity. In some embodiments, a Cas9 nuclease may comprise 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 October 22:163(3): 759-771. In some embodiments, the Cas9 nuclease may comprise 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).

In some embodiments, the Cas9 lacks cleavase activity. In some embodiments, the Cas9 comprises a dCas DNA-binding polypeptide. A dCas polypeptide has DNA-binding activity while essentially lacking catalytic (cleavase/nickase) activity. In some embodiments, the dCas polypeptide is a dCas9 polypeptide. In some embodiments, the Cas9 lacking cleavase activity or the dCas DNA-binding polypeptide is a version of a Cas nuclease (e.g., a Cas9 nuclease discussed above) in which its endonucleolytic active sites are inactivated, e.g., by one or more alterations (e.g., point mutations) in its catalytic domains. See, e.g., US 2014/0186958 A1; US 2015/0166980 A1.
In some embodiments, the Cas9 comprises one or more heterologous functional domains (e.g., is or comprises a fusion polypeptide).
In some embodiments, the heterologous functional domain may facilitate transport of the Cas9 into the nucleus of a cell. For example, the heterologous functional domain may be a nuclear localization signal (NLS). In some embodiments, the Cas9 may be fused with 1-10 NLS(s). In some embodiments, the Cas9 may be fused with 1-5 NLS(s). In some embodiments, the Cas9 may be fused with 1-3 NLS(s). In some embodiments, the Cas9 may be fused with one NLS.

In some embodiments, where more than one NLS is used, one or more NLS may be attached at the N-terminus and/or one or more NLS may be attached at the C-terminus. In some embodiments, one or more NLSs are directly attached to the Cas9. In some embodiments, one or more NLSs are attached to the Cas9 by means of a linker. In some embodiments, the linker is between 3-25 amino acids in length. In some embodiments, the linker is between 3-6 amino acids in length. In some embodiments, the linker comprises glycine and serine. In some embodiments, the linker comprises the sequence of GSVD (SEQ ID NO: 550) or GSGS (SEQ ID NO: 551). It may also be inserted within the Cas9 sequence. In other embodiments, the Cas9 may be fused with more than one NLS. In some embodiments, the Cas9 may be fused with 2, 3, 4, or 5 NLSs.

Guide RNA comprising the guide sequences shown in Table 2 were prepared according to standard methods in a single guide (sgRNA) format. A single AAV vector was prepared that expresses one or more of the guide RNAs and a SaCas9 (for guide sequences having SEQ ID NOs: 11-15 or 27-69) or SluCas9 (for guide sequences having SEQ ID NOs: 243-269). The AAV vector was administered to cells in vitro to assess the ability of the AAV to express the guide RNA and Cas9, edit the targeted exon (see Table 2), and thereby treat DMD.
1. sgRNA Selection
A subset of SaCas9-KKH or SluCas9 sgRNAs found within the DMD gene was selected for indel frequency and profile evaluation. The selected sgRNAs for pair evaluation are shown in Tables 1A-ID and 2 and were prepared according to standard methods. The criteria used to select these sgRNAs included their potential to induce exon reframing and or skipping as a pair, in addition to the existence of a mouse, dog and NHP homologue counterpart. This selection included 43 sgRNAs located within exon 51. The number of predicted off target sites was determined for each sgRNA.
On day one, frozen vials of HsMMs (lot 20TL070666 for
The selected sgRNAs for pair evaluation are shown in Tables 1A-1D and 2 and were chemically synthesized (Sythego). The Cas9 nuclease was recombinant purified SluCas9 (Aldevron). HsMM cells were nucleofected with RNP using the Lonza 4D nucleofector. For each sample, formulated RNP and 0.3e6 of cells were mixed in P5 solution. For dual-cut samples that contain 2 gRNAs, two separate RNPs were formulated with either gRNA of the pair. To formulate RNPs, the gRNA and protein were incubated for about 20 minutes at room temperature. For the experiment shown in
4. Cell Harvesting and gDNA Extraction
To determine cell viability 48 hours after nucleofection, the cells were stained with Hoechst and Propidium Iodide (Life Technologies). Cell viability was then assessed using ImageXpress Micro (Molecular Devices). In general, samples with an overall cell viability above 80% were harvested and analyzed for indel analysis. To isolate genomic DNA from HsMMs, the cells were washed with saline buffer, trypsinized and centrifuged. The cell pellets were treated with lysis buffer from the Maxwell RSC Blood DNA Kit (Promega #AS1400), and genomic DNAs were extracted using a Maxwell® RSC48 instrument (Promega #AS8500) according to the manufacturer's instruction. The concentrations of genomic DNAs were determined using Qubit™ 1×dsDNA HS Assay Kit (Thermo Fisher Scientific Q33231) according to the manufacturer's instruction.
To evaluate indel frequency and profile, human HEK293FT cell line was used. HEK293FT cells were transfected in 12-well plates with 750 ng plasmid+2.5 μL of Lipofectamine 2000. Three days after transfection, cells were trypsinized and sorted for green fluorescent protein (GFP). GFP-positive cells were sorted directly into lysis buffer, and DNA extraction was performed using the Maxwell RSC Blood DNA Kit (Promega #AS1400) and using a Maxwell@ RSC48 instrument (Promega #AS8500) according to the manufacturer's instruction. PCR was then performed on the genomic DNA using DMD exon 51-specific primers that targeted the relevant cut site.
To determine the gene editing efficiency, genomic DNA was amplified using primers flanking the DMD exon 51 genomic region. The following primer sequences were used: MiSeq_hE51_F: TCGTCGGCAGCGTCAGATGTGTATAAGAGACAGCATGAATAAGAGTTTGGCTCAAATTG (SEQ ID NO: 4) and MiSeq_hE51_R: GTCTCGTGGGCTCGGAGATGTGTATAAGAGACAGGAGAGTAAAGTGATTGGTGGAAAAT C (SEQ ID NO: 5). The size of the amplicons was verified by analyzing a small amount of the PCR products on 2% E-gels (Thermo Fisher Scientific). The PCR product was purified using AMPure XP beads (A63881). The purified PCR product was amplified again with primers that contain barcodes and Illumina adaptors. Multiple barcoded samples were pooled, combined with the PhiX library, and loaded onto the Illumina Mi-Seq platform. MiSeq Reagent Kit v3 (MS-102-3003) was used to produce a 600-cycle run.
