[0001] Cross-reference of related applications This application claims the rights and priority of PCT application number PCT / CN2023 / 088738, filed on 17 April 2023. The contents of these applications are incorporated herein by reference for all purposes.
[0002] A polynucleotide is provided comprising a nucleotide sequence encoding a biomolecule (e.g., human α-galactosidase A), a nucleotide sequence encoding a promoter (e.g., a hepatocyte-specific promoter or a hepatocyte-myocyte dual-specific promoter), or a nucleotide sequence encoding an expression cassette (e.g., a human α-galactosidase A expression cassette). Furthermore, promoters, expression cassettes, vectors, host cells, gene delivery systems (e.g., recombinant adeno-associated virus (AAV) particles and recombinant viral particles such as nonviral gene delivery systems), related pharmaceutical compositions, and methods for using them are also provided. Such compositions and methods are particularly suitable for gene therapy, and especially for lysosomal storage disorders, including Fabry disease. [Background technology]
[0003] Gene therapy (including gene therapy using AAV) has the potential to be a promising treatment option for many diseases.
[0004] Lysosomal storage disorders are genetic metabolic disorders characterized by the accumulation of abnormal amounts of substrate due to lysosomal dysfunction in cells of various organs. For example, Fabry disease (FD) is a rare X-linked metabolic disorder caused by a deficiency of the lysosomal enzyme α-galactosidase A (α-Gal A) resulting from a pathogenic mutation in the GLA gene. The gradual accumulation of substrate within lysosomes leads to cellular dysfunction and multi-organ damage.

[0044] definition The techniques and programs described or referenced herein include those commonly understood and / or used by those skilled in the art, such as Green and Sambrook, *Molecular Cloning: A Laboratory Manual*, 4th edition; Cold Spring Harbor Laboratory (Cold Spring Harbor, NY 2012); Current Protocols in Molecular Biology (Ausubel et al. eds., 2003); Therapeutic Monoclonal Antibodies: From Bench to Clinic (An ed. 2009); Monoclonal Antibodies: Methods and Protocols (Albitar ed. 2010); and Antibody Engineering This includes the widely used methods described in Vols 1 and 2 (Kontermann and Dubel eds., 2d ed. 2010).
[0045] Unless otherwise defined herein, technical and scientific terms used herein have the meanings generally understood by those skilled in the art. The following terms are used to describe this specification.
[0046] The terms “polypeptide,” “peptide,” and “protein” are used interchangeably herein and refer to polymers of amino acids of any length. The polymers may be linear or branched, may contain modified amino acids, or may be interrupted by non-amino acids. These terms also encompass naturally occurring or interveningly modified amino acid polymers, such as disulfide bond formation, glycosylation, lipidation, acetylation, phosphorylation, or any other operation or modification. The definitions further include polypeptides containing one or more amino acid analogs, including, but not limited to, non-natural amino acids and other modifications known in the art.
[0047] The terms “polynucleotide” or “nucleic acid,” which may be used interchangeably herein, refer to polymers of nucleotides of any length, including DNA (including cDNA) and RNA (including mRNA). Nucleotides may be deoxyribonucleotides, ribonucleotides, modified nucleotides or bases and / or analogs thereof, or any substrate that can be incorporated into the polymer by DNA or RNA polymerase or synthetic reactions. Polynucleotides may be single-stranded or double-stranded. Polynucleotides may be linear or cyclic. Polynucleotides may include modified nucleotides, such as methylated nucleotides and their analogs. As used herein, “oligonucleotide” refers to a common, but not necessarily, short, synthetic polynucleotide of about 200 nucleotides in length. The terms “oligonucleotide” and “polynucleotide” are not mutually exclusive. The above descriptions of polynucleotides are equally and fully applicable to oligonucleotides. Unless otherwise specified, the left end of any single-stranded polynucleotide sequence disclosed herein is the 5' end, and the left direction of a double-stranded polynucleotide sequence is referred to as the 5' direction. The direction of addition of a nascent RNA transcript from 5' to 3' is called the transcription direction, the sequence region located at the 5' end of the RNA transcript on the DNA strand and having the same sequence as the 5' RNA transcript is called the “upstream sequence”, and the sequence region located at the 3' end of the RNA transcript on the DNA strand and having the same sequence as the 3' RNA transcript is called the “downstream sequence”. In certain embodiments, the polynucleotides described herein may be optimized by alternative or preferred codon use for a particular type of host cell or delivery target cell. Codon optimization can be performed by using any suitable method known in the art (e.g., using suitable software known in the art).
[0048] As used herein, “isolated polynucleotide” or “isolated nucleic acid” refers to nucleic acids, such as RNA, DNA, or mixed nucleic acids, which are typically substantially isolated from other genomic DNA sequences and proteins or complexes (e.g., ribosomes and polymerases) naturally associated with the native sequence. “Isolated” nucleic acid molecules are nucleic acid molecules isolated from other nucleic acid molecules present in the natural source of the nucleic acid molecule. Furthermore, “isolated” nucleic acid molecules, such as cDNA molecules, may substantially not contain other cellular material or culture media if produced by recombinant technology, or substantially not contain chemical precursors or other chemicals if chemically synthesized. The term encompasses nucleic acid sequences removed from their naturally occurring environment, recombinant or cloned DNA isolates and chemically synthesized analogs, or analogs biosynthesized in heterologous systems. A substantially pure molecule may include the isolated form of the molecule. Specifically, “isolated” nucleic acid molecules encoding polypeptides as described herein are nucleic acid molecules identified and isolated from at least one contaminated nucleic acid molecule, which is typically associated with it in its production environment.
[0049] As used herein, the term “homologousity” refers to the percentage of identity between two polynucleotides or two polypeptide parcels. Two DNA or polypeptide sequences are “substantially homologous” to each other if, in a molecule of a limited length, they exhibit sequence identity of at least about 50%, at least about 75%, at least about 80%–85%, at least about 90%, at least about 95%–98%, at least about 99%, or any percentage in between. As used herein, substantially homologous also refers to sequences that exhibit complete identity with a given DNA or polypeptide sequence.
[0050] As used herein, the term “identity” refers to the exact nucleotide-to-nucleotide or amino acid-to-amino acid correspondence between two polynucleotide or polypeptide sequences. Methods for measuring identity percentage are known in the art. For example, identity percentage can be determined by directly comparing the sequence information between two molecules by comparing the sequences, counting the exact number of matches between the two comparison sequences, dividing by the length of the shorter sequence, and multiplying the result by 100. To assist in the analysis, existing computer programs such as ALIGN, Dayhoff, MOin Atlas of Protein Sequence and Structure MODayhoff ed., 5 Suppl.3:353-358, National Biomedical Research Foundation, Washington, DC can be used, and this program is a modified version for peptide analysis of the local homology algorithm described in the paper by Smith and Waterman (Advances in Appl. Math. 2:482-489, 1981). Programs for determining nucleotide sequence identity can be obtained from the Wisconsin sequencing package version 8 (available from Genetics Computer Group, Madison, Wis), including programs such as BESTFIT, FASTA, and GAP, which also rely on the Smith and Waterman algorithms. These programs are easily used with the default parameters recommended by the manufacturer and described in the Wisconsin sequencing package mentioned above. For example, the percentage of identity between a particular nucleotide sequence and a reference sequence can be determined using the Smith and Waterman homology algorithms, along with a default scoring table and a gap penalty at six nucleotide positions.Another method for establishing the identity percentage in the context of this invention is to use the MPSRCH program package, copyrighted by Arberger University, developed by John F. Collins and Shane S. Sturrok, and published by IntelliGenetics, Inc. (Mountain View, CA). From this software package, the Smith-Waterman algorithm can be employed, and default parameters (e.g., gap start penalty 12, gap extension penalty 1, gap 6) are used in the scoring table. Based on the generated data, the "matching" value reflects the "sequence identity." Other suitable programs for calculating the identity or similarity percentage between sequences are generally known in the art; for example, another alignment program is BLAST, which is used with default parameters. For example, BLASTN and BLASTP can be used by using the default parameters: Genetic code = standard; filter = none; strand = both; cutoff value = 60; expected value = 10; matrix = BLOSUM62; description = 50 sequences; sorting criterion = high score; database = non-duplicate, GenBank+EMBL+DDBJ+PDB+GenBank CDS translation+Swiss protein+Spupdate+PIR. Details of these programs are publicly known in this field. Alternatively, homology can be determined by hybridizing polynucleotides under conditions that form stable double helixes between homologous regions, then digesting with a single-strand specific nuclease and determining the size of the digested fragments. Substantially homologous DNA sequences can be identified in Southern hybridization experiments under stringent conditions, for example, defined for the particular system in question. Defining appropriate hybridization conditions is within the technical scope of this field. See, for example, Sambrook et al., op. cit.; DNA cloning, op. cit.; nucleic acid hybridization, op. cit.
[0051] As used herein, the term “vector” refers to a substance for supporting or encapsulating a nucleic acid sequence, for example, to introduce the nucleic acid sequence into a host cell. Applicable vectors include, for example, expression vectors, plasmids, bacmids, cosmids, constructs, phage vectors, viral vectors, episomes, and artificial chromosomes, which may contain a selectable sequence or marker that can be manipulated for stable integration into the chromosomes of a host cell. Vectors may also contain one or more selectable marker genes and appropriate expression regulatory sequences. Selectable marker genes that may be included may, for example, provide resistance to antibiotics or toxins, compensate for nutritional deficiencies, or provide essential nutrients that are not present in the culture medium. Expression regulatory sequences may include constitutive and inductive promoters, transcriptional enhancers, transcriptional terminators, etc., known in the art. When co-expressing two or more nucleic acid molecules, the two nucleic acid molecules can be inserted, for example, into a single expression vector or a standalone expression vector. The introduction of nucleic acid molecules into host cells can be confirmed by methods known in the art. Such methods include, for example, nucleic acid analysis such as Northern blotting or mRNA polymerase chain reaction (PCR) amplification, Western blotting for gene product expression, or other appropriate analytical methods for testing the expression of the introduced nucleic acid sequence or its corresponding gene product. The term “vector” includes clone and expression vectors, as well as viral vectors. In certain embodiments, the vectors provided herein are recombinant viral vectors. In specific embodiments, the vectors provided herein are recombinant AAV vectors.
[0052] As used herein, the term “recombinant AAV vector (rAAV vector)” refers to a polynucleotide vector comprising a nucleic acid sequence from AAV and one or more heterologous sequences (i.e., non-AAV-derived nucleic acid sequences). In some embodiments, one or more heterologous sequences are flanked to at least one (two in certain embodiments) AAV terminal inverted repeat sequences (ITRs). In some embodiments, such an rAAV vector may be replicated and packaged into an infectious viral capsid particle, for example, when present in a host cell that is infected with a suitable helper virus (or expresses suitable helper function) and expresses AAV rep and cap gene products (i.e., AAV Rep and Cap proteins). The rAAV vector may be incorporated into a relatively large polynucleotide (e.g., a chromosome or another vector, e.g., a plasmid for cloning or transfection) and may be “rescued” by replication and packaging in the presence of AAV packaging function and suitable helper function. rAAV vectors may take any of the following forms, including, but are not limited to, plasmids, linear artificial chromosomes, complexes with lipids, encapsulation in liposomes, and encapsulation in viral capsid particles (particularly AAV particles). By packaging rAAV vectors into AAV capsids, "recombinant adeno-associated virus capsid particles (rAAV particles)" can be produced.
[0053] As used herein, the term “heterogeneous,” used in conjunction with nucleic acid sequences such as coding sequences and regulatory sequences, refers to sequences that do not generally bind and / or sequences that are not generally associated with a particular cell. Therefore, the “heterogeneous” region of a nucleic acid construct or vector is a nucleic acid segment that does not exist in nature with other molecules, and is linked to or within another nucleic acid molecule. For example, the heterogeneous region of a nucleic acid construct may include a coding sequence to which sequences unrelated to the coding sequence in nature have been flanked. Another example of a heterogeneous coding sequence is a construct in which the coding sequence itself does not exist in nature (e.g., a synthetic sequence with codons different from those of a native gene).
[0054] As used herein, the term “flanking” in relation to sequences in which other elements are flanked indicates the presence of one or more flanking elements upstream and / or downstream, i.e., 5' and / or 3', of the sequence. The term “flanking” does not necessarily indicate that the sequence is continuous. For example, an intervening sequence may exist between a nucleic acid encoding a transgene and a flanking element. A sequence (e.g., a transgene) in which two other elements (e.g., ITRs) are “flanked” indicates that one element is located at 5' of the sequence and the other at 3', but an intervening sequence may exist between them.
[0055] As used herein, the term “terminal inverted repeat” or “ITR” sequence refers to a relatively short sequence found at the opposite ends of a viral genome. “AAV terminal inverted repeat (ITR)” sequences are known in the art and are generally sequences of approximately 145 nucleotides present at both ends of a natural single-stranded AAV genome. The outermost 125 nucleotides of an ITR can exist in one of two alternative orientations, resulting in heterogeneity between different AAV genomes and between the two ends of a single AAV genome. These outermost 125 nucleotides further contain several short self-complementary regions (designated as regions A, A', B, B', C, C', and D), which allow for intra-strand base pairing in this region of the ITR.
[0056] A "coding sequence," or a sequence that "codes" a selected polypeptide, is a nucleic acid molecule that, when controlled by appropriate regulatory sequences, is transcribed (in the case of DNA) and translated (in the case of mRNA) into a polypeptide. The boundaries of the coding sequence are determined by the 5' (amino) terminal start codon and the 3' (carboxyl) terminal translation termination codon. The transcription termination sequence may be located at the 3' position of the coding sequence.
[0057] The term "regulatory sequence" refers to a DNA sequence necessary for the expression of a manipulably linked coding sequence in a specific host organism. Regulatory sequences suitable for prokaryotes include, for example, promoters, arbitrary operon sequences, and ribosome binding sites. Eukaryotic cells are known to utilize promoters, polyadenylation signals, and enhancers.
[0058] As used herein, when used to refer to nucleic acids or amino acids, the terms “operatably linked” and similar phrases (e.g., genetically fused) refer, respectively, to the operational linkage of nucleic acid sequences or amino acid sequences arranged in a functional relationship with one another. For example, operationally linked promoters, enhancer elements, open reading frames, 5' and 3' UTRs, and terminator sequences result in the precise production of nucleic acid molecules (e.g., RNA). In some embodiments, operationally linked nucleic acid elements induce transcription of an open reading frame, ultimately producing a polypeptide (i.e., expression of the open reading frame). As another example, an operationally linked peptide is a peptide in which functional domains are arranged at appropriate distances from each other to confer a desired function of each domain.
[0059] As used herein, the term “expression cassette” or “nucleic acid expression cassette” refers to a nucleic acid molecule comprising one or more transcriptional regulatory elements (e.g., promoters, response elements, polyadenylated sequences, and introns) that guide the expression of biomolecules in one or more desired cell types, tissues, or organs, for example, guiding (trans) gene expression. Typically, these may also include guiding the expression of endogenous genes in cells into which the expression cassette has been inserted into a nucleic acid sequence, but also include transgenes.
[0060] As used herein, the term “response element (RE)” refers to a transcriptional regulatory element, particularly a non-coding transcriptional regulatory element, that can regulate and / or control gene transcription. A response element comprises at least one transcription factor binding site (TFBS). A response element may be located upstream (e.g., in the promoter region) or downstream (e.g., in the 3'UTR) of a gene regulated in vivo, or in the vicinity or further away from the gene. A response element may be a naturally occurring sequence or a non-naturally occurring sequence.
[0061] As used herein, the term “enhancer” refers to a nucleic acid sequence that increases the transcription rate by increasing the activity of the promoter.
[0062] As used herein, the term “promoter” in its general sense refers to a nucleotide region containing a DNA regulatory sequence, where the regulatory sequence originates from a gene that binds to RNA polymerase and initiates transcription of a downstream (3' direction) coding sequence. Transcription promoters may include “inductive promoters” (where the expression of a polynucleotide sequence manipulably linked to the promoter is induced by an analyte, cofactor, regulatory protein, etc.), “repressive promoters” (where the expression of a polynucleotide sequence manipulably linked to the promoter is induced by an analyte, cofactor, regulatory protein, etc.), and “constitutive promoters.”
[0063] As used herein, the term “TATA box” refers to a DNA sequence found in the promoter region of a gene that can bind to TATA-binding protein and transcription factor II D during the process of DNA dissociation and binding with RNA polymerase II. TATA box sequences typically include a TATAAA sequence and generally contain an additional 3' adenine nucleotide.
[0064] As used herein, the term “transcription start site” refers to the location where transcription begins at the 5' end of a gene sequence.
[0065] As used herein, the term "ORF (Open Reading Frame)" refers to a sequence of nucleotide triplets (codons) that code for an amino acid. These sequences can typically be translated into peptides.
[0066] As used herein, the term “transcription factor (TF)” refers to a protein that binds to a specific DNA sequence and thereby regulates the transfer (or transcription) of genetic information from DNA to RNA. TFs perform this function alone or in conjunction with other proteins in a complex by promoting (as an activator) or inhibiting (as a repressor) the recruitment of RNA polymerase (the enzyme that transcribes genetic information from DNA to RNA) to a specific gene. The specific DNA sequence to which a TF binds is called a response element (RE) or regulatory element. Other names include cis-elements and cis-acting transcription regulatory elements. Transcription factors interact with their binding sites through a combination of electrostatic (hydrogen bonding is an exception) and van der Waals forces. Due to the nature of these chemical interactions, most transcription factors bind to DNA in a sequence-specific manner. However, not all bases at the transcription factor binding site actually interact with the transcription factor. Also, some of these interactions may be weaker than others. Therefore, many transcription factors can bind not just one sequence, but a subset of closely related sequences, each with a different interaction strength. For example, the covalent binding site of TATA-binding protein (TBP) is TATAAAA, but TBP transcription factors may bind to similar sequences, such as TATATAT or TATAA. Transcription factors (TFs) can be classified based on many aspects. These include the protein structure, the secondary, tertiary, and quaternary structures and properties of the DNA binding sequence, the interaction with the DNA double helix, and the metal and other binding properties. The JASPAR database and TRANSFAC (TRANSFAC.RTM.7.0 Public 2005) are two network-based databases of transcription factors, including experimentally proven binding sites and regulatory genes.
[0067] As used herein, the broad term “transgene” means any heterologous nucleotide sequence incorporated into a vector, such as a viral vector, for expression in target cells, and may be associated with an expression regulatory sequence, such as a promoter. Those skilled in the art will understand that the expression regulatory sequence is selected based on its ability to promote the expression of the transgene in target cells. Examples of transgenes are nucleic acids encoding therapeutic polypeptides or detectable markers.
[0068] As used herein, the terms “AAV capsid,” “AAV capsid protein,” or “AAV cap” refer to the protein encoded by the AAV capsid protein (cap) gene (e.g., VP1, VP2, and VP3) or its variants. For example, the terms include, but are not limited to, capsid proteins derived from any AAV serotype, such as AAV1, AAV2, AAV2i8, AAV3, AAV3-B, AAV4, AAV5, AAV6, AAV7, AAV8, AAVrh8, AAVrh8R, AAV9, AAV10, AAVrh10, AAV11, AAV12, AAV13, AAV-DJ, AAV-2 / 1, AAV2 / 6, AAV2 / 7, AAV2 / 8, AAV2 / 9, AAV LK03, AAVrh10, AAVrh74, AAV44-9, or their variants. The term further includes capsid proteins expressed by or derived from recombinant AAVs, such as chimeric AAVs.
[0069] As used herein, the term “AAV capsid particle” or “AAV particle” comprises at least one AAV capsid protein (e.g., VP1 protein, VP2 protein, VP3 protein or a variant thereof) and optionally encapsulates nucleic acids from an AAV genome (including rAAV genome) or nucleic acids from an AAV genome (including rAAV genome).
[0070] The term "serotype," as used in relation to vectors or viral capsids, is defined by different immunological spectra based on the capsid protein sequence and capsid structure.
[0071] As used herein, with respect to a viral capsid or particle, the term “chimera” means that the capsid or particle contains sequences derived from different parvoviruses, preferably different AAV serotypes, as described, for example, in U.S. Patent No. 6,491,907 by Rabinowitz et al., the disclosure of which is incorporated herein by whole reference.
[0072] The term “recombinant” means different from the genetic entities normally found in nature. When applied to polynucleotides, genes, promoters, expression cassettes, etc., it means the products of various combinations of cloning, restriction, ligation and / or synthesis processes, and other programs that produce constructs different from naturally occurring polynucleotides, genes, promoters, expression cassettes, etc. When used herein to describe viruses, the term “recombinant” refers to a virus that has been genetically altered, for example, by adding or inserting a heterologous nucleic acid construct into a particle. For example, as used herein, the term “recombinant AAV particle” or “rAAV” refers to an AAV that has been genetically altered, for example, by deletion or other mutation of the endogenous AAV gene, and / or by adding or inserting a heterologous nucleic acid construct into the polynucleotides of an AAV particle.
[0073] As used herein, “specific hybridization” means that the antisense compound has sufficient complementarity to induce the desired effect between the antisense oligonucleotide and the target nucleic acid, and exhibits minimal or no effect on the non-target nucleic acid under conditions where specific binding is required, i.e., physiological conditions under which it is measured and treated in the body.
[0074] As used herein, “stringent hybridization conditions” or “stringent conditions” means conditions under which an oligo compound hybridizes with its target sequence, but with the fewest number of other sequences.
[0075] As used herein, the terms “transfection,” “transformation,” or “transduction” refer to the process of transferring or introducing exogenous nucleic acids into host cells. A “transfected,” “transformed,” or “transduced” cell is a cell that has been transfected, transformed, or transduced with exogenous nucleic acids. For example, the term “transfection” means the intracellular uptake of exogenous DNA, and a cell is “transfected” when exogenous DNA is introduced into the cell membrane. Many transfection techniques are known in this field. For example, Graham et al. (1973) Virology, 52:456, Green and Sambrook, Molecular Cloning: A Laboratory Manual, 4 th See Ed., Cold Spring Harbor Laboratory (Cold Spring Harbor, NY 2012), Davis et al.

[0214] In one embodiment, a vector comprising a polynucleotide described herein (for example, a polynucleotide described in Section 5.2.1) is provided.
[0215] In one embodiment, a vector is provided that includes a promoter as described herein (for example, the promoter described in Section 5.2.2).
[0216] In one embodiment, a vector is provided that includes an expression cassette described herein (for example, an expression cassette described in Section 5.2.3).
[0217] In various embodiments, the vectors described herein are plasmids. In various embodiments, the vectors described herein are expression vectors.
[0218] In various embodiments, the vectors described herein are recombinant viral vectors. In various embodiments, the vectors described herein are recombinant AAV vectors.
[0219] Further explanation of vectors is provided below in this section and in Section 5.1.
[0220] The gene delivery systems provided herein include, for example, recombinant AAV particles and recombinant viral particles such as nonviral gene delivery systems.
[0221] A viral particle consists of a viral genome enclosed within a protein shell called a capsid. An "AAV particle" refers to an AAV virus consisting of at least one AAV capsid protein and the packaged AAV genome. The AAV genome is a linear, single-stranded DNA molecule containing terminal inversion repeats (ITRs) at the 5' and 3' ends of the viral genome. ITRs act as a cis-acting origin for DNA replication and as a packaging signal for the viral genome.
[0222] In one embodiment, recombinant viral particles comprising the polynucleotides described herein (for example, the polynucleotides described in Section 5.2.1) are provided.
[0223] In one embodiment, recombinant viral particles are provided that include a recombinant viral genome containing an expression cassette described herein (for example, an expression cassette described in Section 5.2.3).
[0224] In one aspect, recombinant virus particles are provided that contain a vector as described herein (e.g., a vector as described in this section).
[0225] In one aspect, recombinant AAV particles are provided that contain (a) an AAV capsid and (b) a recombinant AAV genome that contains an expression cassette as described herein (e.g., an expression cassette as described in Section 5.2.3) flanked by AAV inverted terminal repeats (ITRs).
[0226] Many viral systems have been developed for transferring genes into mammalian cells. Examples of viral vectors include, but are not limited to, adenoviral vectors, adeno-associated viral vectors, lentiviral vectors, retroviral vectors, vaccinia vectors, herpes simplex virus vectors, and derivatives thereof. Viral vector technology is well known in the art and is described, for example, in Green and Sambrook, Molecular Cloning: A Laboratory Manual, 4 th Ed ., Cold Spring Harbor Laboratory (Cold Spring Harbor, N.Y. 2012), as well as in other virology and molecular biology manuals.
[0227] In certain embodiments, the viral vectors or viral particles provided herein are derived from adenoviruses. Exemplary vectors are based on or derived from HAd5, ChAd3, HAd26, HAd6, AdCH3NSmut, HAd35, ChAd63, HAd4, and rcAd26. Recombinant adenovirus vectors can be constructed according to methods known in the art. See, for example, O'Connor et al., Virology, 217(1):11-22 (1996); Hardy et al., Journal of Virology, 73(9):7835-7841 (1999); Hardy et al., Journal of Virology, 71(3):1842-1849 (1997). In some embodiments, third-generation adenovirus vectors (also known as “high-capacity adenovirus vectors” (HCAds), helper-dependent, or “gutless” adenovirus vectors) may be used herein to deliver longer sequences. In some embodiments, the nucleic acid construct of interest is cloned into an adenovirus vector containing only the ITR and packaging signal. The helper adenovirus vector can be co-transfected into HEK cells to generate adenovirus particles. See Lee et al., Genes and Diseases, 4(2):43-63 (2007).
[0228] In certain embodiments, the viral vectors or viral particles provided herein are derived from lentiviruses. Exemplary vectors are based on or derived from HIV-1, HIV-2, SIVSM, SIVAGM, EIAV, FIV, VNV, CAEV or BIV. Lentiviral vectors can be produced according to methods known in the art, such as those described in Chribs et al., BMC Biotechnology, 13:98 (2003); Merten et al., Mol Ther Methods Clin Dev., 13(3):160-17 (2016); Durand and Cimarelli, Viruses, 3:132-159 (2011). In some embodiments, herein, third-generation self-inactivating lentiviral vectors are used.
[0229] In certain embodiments, the viral vectors or viral particles provided herein are derived from herpes simplex virus (HSV). In some embodiments, the herpes simplex virus is herpes simplex type 1 virus (HSV-1), herpes simplex type 2 virus (HSV-2), or any derivatives thereof. Exemplary vectors are based on or derived from HSV-1, HSV-2, CMV, VZV, EBV and KSHV. For example, they can be constructed according to methods known in the art, such as those described in U.S. Patent Nos. 7,078,029, 6,261,552, 5,998,174, 5,879,934, 5,849,572, 5,849,571, 5,837,532, 5,804,413 and 5,658,724, and International Patent Applications WO 91 / 02788, WO 96 / 04394, WO 98 / 15637 and WO 99 / 06583, which are hereby incorporated by reference in their entirety.
[0230] In some embodiments, the HSV-based vectors provided herein are amplicon vectors. In other embodiments, the HSV-based vectors provided herein are replication-defective vectors. In other embodiments, the HSV-based vectors provided herein are replication-competent vectors.
[0231] Amplicons are plasmid-derived vectors engineered to contain HSV DNA replication origins (oris) and HSV cleavage and packaging recognition sequences (pacs). When amplicons are transfected into mammalian cells with HSV helper function, they replicate, form head-tail multimers, and package into viral particles. Currently, there are two main methods used for producing amplicon particles: one is based on infection with a deficient helper HSV, and the other is based on transfection of the HSV-1 gene, such as a pair of pac deletion overlap cosmids or BAC-HSV-1 with both pac deletion and ICP27 deletion. In some embodiments, the amplicons used herein are capable of accommodating large fragments of non-toxic exogenous DNA (e.g., up to 152 kb) containing multiple copies (e.g., up to 15 copies) of the transgene.
[0232] In some embodiments, the HSV-based vectors used herein are deficient in at least one essential HSV gene, and the HSV-based vectors may further include deletions of one or more non-essential genes. In some embodiments, the HSV-based vectors are replication-deficient. Most replication-deficient HSV-based vectors include deletions to remove one or more immediate early, early, or late HSV genes to prevent replication. In other embodiments, the HSV-based vectors are deficient in an immediate early gene selected from the group consisting of ICP0, ICP4, ICP22, ICP27, ICP47 and combinations thereof. In specific embodiments, the HSV-based vectors are deficient in all of ICP0, ICP4, ICP22, ICP27, and ICP47. Exemplary replication-competent vectors include NV-1020 (HSV-1), RAV9395 (HSV-2), AD-472 (HSV-2), NS-gEnull (HSV-1), and ImmunoVEX (HSV-2). Exemplary replication-defect type vectors include dl5-29 (HSV-2), dl5-29-41L (HSV-1), DISC-dH (HSV-1 and HSV-2), CJ9gD (HSV-1), TOH-OVA (HSV-1), d106 (HSV-1), d81 (HSV-1), HSV-SIV d106 (HSV-1), and d106 (HSV-1).
[0233] Replication-deficient HSV-based vectors are typically produced in complementary cell lines that provide adequate levels of gene function necessary for viral replication, even if it is absent in the replication-deficient HSV-based vector, thereby generating high-titer viral vector stocks. Exemplary cell lines complement at least one replication-essential gene function absent in the replication-deficient HSV-based vector, and in some embodiments, complement all replication-essential gene functions. For example, an HSV-based vector lacking ICP0, ICP4, ICP22, ICP27, and ICP47 can be complemented by the human osteosarcoma cell line U2OS. Cell lines can also complement non-essential genes (e.g., UL55) whose deficiency reduces growth or replication efficiency. Complementary cell lines can complement defects in at least one replication-essential gene function encoded by early regions, immediate early regions, late regions, viral packaging regions, virus-associated regions, or combinations thereof, and include all HSV functions (e.g., enabling the proliferation of HSV amplicons containing minimal HSV sequences (e.g., terminal inverted repeats and packaging signals only, or ITR and HSV promoter only)). In some embodiments, a further feature of the cell system is the inclusion of complementary genes that do not overlap with the HSV-based vector, which minimizes, and virtually eliminates, the possibility of the HSV-based vector genome being recombined with cellular DNA. Therefore, the presence of HSVs capable of replication, which must be avoided in the vector library, is minimized, making it suitable for certain therapeutic purposes, particularly gene therapy. The construction of the complementary cell system relates to standard molecular biology and cell culture techniques known in this field.
[0234] In certain embodiments, the viral vectors or viral particles provided herein are derived from adeno-associated viruses (AAVs). A more detailed description of AAVs is provided in Section 5.3.1 below.
[0235] The nucleotide sequences, promoters, and expression cassettes described herein can be cloned into viral vectors using any known molecular cloning method in the art, which may include, for example, the use of restriction endonuclease sites and one or more selection markers.
[0236] In one embodiment, the viral vector genome includes at least one element that enhances the specificity and expression of the transgene target (see, for example, Powell et al., Viral Expression Cassette Elements to Enhance Transgene Target Specificity and Expression in Gene Therapy, 2015, the contents of which are incorporated herein by reference), such as an intron or a synthetic intron having a modified sequence from a mammalian genome. Non-limiting examples of introns include MVM (67-97 bps), F.IX cleavage intron 1 (300 bps), β-globulin SD / immunoglobulin heavy chain splice acceptor (250 bps), adenovirus splice donor / immunoglobulin splice acceptor (500 bps), SV40 late splice donor / splice acceptor (19S / 16S) (180 bps), and hybrid adenovirus splice donor / IgG splice acceptor (230 bps). In one embodiment, the length of the intron may be 100 to 500 nucleotides. The length of the intron may be 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 171, 172, 173, 174, 175, 176, 177, 178, 179, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, 300, 310, 320, 330, 340, 350, 360, 370, 380, 390, 400, 410, 420, 430, 440, 450, 460, 470, 480, 490, or 500.
[0237] In some embodiments, the viral vector further includes a selection marker gene or a reporter gene to select cells expressing a protein from a population of host cells transfected with the viral vector. Both the selection marker and reporter genes may have appropriate regulatory sequences flanked to enable expression in host cells. For example, the viral vector may include transcription and translation terminators, start sequences, and promoters to regulate the expression of nucleic acid sequences.
[0238] The nonviral gene delivery systems provided herein include, but are not limited to, lipid-based gene delivery systems (e.g., liposome-based gene delivery systems), peptide-based gene delivery systems, inorganic gene delivery systems, and polymer delivery systems. Non-exclusive exemplary nonviral gene delivery systems are described, for example, in Sung and Kim, 2019, Biomator Res 23:8; Zu and Gao, 2021, AAPS J 23:78; and Lan et al., 2022, Mol Cancer 21:71, the entirety of which is incorporated herein.

In some embodiments, the rAAV vector includes an ITR derived from AAV7. In some embodiments, the rAAV vector includes an ITR derived from AAV8. In some embodiments, the rAAV vector includes an ITR derived from AAVrh8. In some embodiments, the rAAV vector includes an ITR derived from AAVrh8R.

In some embodiments, the rAAV vector includes an ITR derived from AAV-DJ. In some embodiments, the rAAV vector includes an ITR derived from AAV LK03. In some embodiments, the rAAV vector includes an ITR derived from AAVrh74.
[0251] In some embodiments, the 5' and 3' ITRs flanked in the nucleotide sequences of the rAAV vectors provided herein are the same and derived from the same AAV serotype. In other embodiments, the 5' and 3' ITRs flanked in the nucleotide sequences of the rAAV vectors provided herein are different and / or derived from different AAV serotypes.
[0252] In some embodiments, an rAAV vector containing an expression cassette of interest with a flanked AAV ITR may be constructed by directly inserting the cassette of interest into the AAV genome, for example, into an excised AAV open reading frame, and some portions of the AAV genome may be selectively deleted, as described in WO1993 / 003769; Kotin (1994) Human Gene Therapy 5:793-801; Shelling and Smith (1994) Gene Therapy 1:165-169; and Zhou et al. (1994) J.Exp.Med.179:1867-1875.
[0253] In another embodiment, AAV ITRs are excised from an AAV genome or an AAV vector containing such ITRs and fused to the 5' and 3' of an expression cassette of interest present in another vector using standard ligation techniques.
[0254] In certain embodiments, the rAAV vectors provided herein include a recombinant autocomplementary genome. rAAVs containing an autocomplementary genome can typically rapidly form a double-stranded DNA molecule by some of their complementary sequences (e.g., coding and non-coding strands of a complementary gene). More specifically, in some embodiments, the rAAV vectors provided herein include an rAAV genome comprising a first heterologous polynucleotide sequence (e.g., a therapeutic transgene coding strand) and a second heterologous polynucleotide sequence (e.g., a non-coding or antisense strand of a therapeutic transgene), wherein the first heterologous polynucleotide sequence can form intra-strand base pairs with the second polynucleotide sequence. In some embodiments, the first and second heterologous polynucleotide sequences are linked by a sequence that promotes intra-strand base pairing (e.g., a hairpin DNA structure). In some embodiments, the first and second heterologous polynucleotide sequences are linked by a mutated ITR to prevent the rep protein from cleaving the viral genome at the mutated ITR. rAAV vectors containing a self-complementary genome can be manufactured using methods known in the art, for example, as described in U.S. Patent Nos. 7,125,717; 7,785,888; 7,790,154; 7,846,729; 8,093,054; and 8,361,457.
[0255] In some embodiments, the size of the recombinant viral genome in the rAAV vector provided herein is less than about 5 kilobases (kb). In some embodiments, the size of the recombinant viral genome in the rAAV vector provided herein is less than about 4.5 kb. In some embodiments, the size of the recombinant viral genome in the rAAV vector provided herein is less than about 4.0 kb. In some embodiments, the size of the recombinant viral genome in the rAAV vector provided herein is less than about 3.5 kb. In some embodiments, the size of the recombinant viral genome in the rAAV vector provided herein is less than about 3.0 kb. In some embodiments, the size of the recombinant viral genome in the rAAV vector provided herein is less than about 2.5 kb.
[0256] The capsid protein may be derived from the same serotype as the ITR or a derivative thereof. The capsid may be from a different serotype than the ITR. For example, in certain embodiments, the AAV particles include AAV2 ITR and AAV6 capsid (AAV2 / 6), AAV2 ITR and AAV7 capsid (AAV2 / 7), AAV2 ITR and AAV8 capsid (AAV2 / 8), or AAV2 ITR and AAV9 capsid (AAV2 / 9).
[0257] Naturally occurring AAV capsids contain AAV VP1, VP2, and VP3 capsid proteins, each encoded by a splicing variant of the AAV cap gene. Typically, AAV particles contain three proteins, VP1, VP2, and VP3, and since VP2 and VP3 are cleavage forms of VP1, they also contain sequences found in VP1. Usually, the amino acid sequence of VP1 defines the serotype of the capsid. For example, if the VP1 capsid protein encodes the AAV2 VP1 protein, the AAV is of the AAV2 serotype, but if the VP1 capsid protein encodes the AAV9 VP1 protein, the AAV is of the AAV9 serotype.
[0258] Generally, AAV capsid proteins contain multiple variable regions (VRs) and constant regions located between them. The "GH loop" is a ring sequence in which β-strands G and β-strand H are flanked within the internal β-barrel of the AAV capsid protein, and it contains variable regions VR IV to VR VIII.
[0259] The sequences of the VP2 and VP3 capsid proteins and the positions of various domains (e.g., the variable region and the GH loop) can be easily and conventionally determined from a given VP1 sequence by appropriate methods known to those skilled in the art (e.g., by comparing or aligning the VP1 sequence with an annotated VP1 sequence (preferably an annotated VP1 sequence from a closely related AAV species) using an appropriate algorithm). Preferably, such annotated VP1 sequence is an annotated wild-type AAV VP1 sequence.
[0260] In some embodiments, the AAV capsid proteins (e.g., VP1, VP2, and / or VP3) in the rAAV particles of the present invention are not naturally occurring capsid proteins. In some embodiments, the AAV capsid proteins (e.g., VP1, VP2, and / or VP3) are derived from naturally occurring capsid proteins.
[0261] In some embodiments, the AAV capsid protein is the VP1 capsid protein. In other embodiments, the AAV capsid protein is the VP2 capsid protein. In other embodiments, the AAV capsid protein is the VP3 capsid protein. In some embodiments, the rAAV particles contain the VP1 capsid protein, the VP2 capsid protein, and / or the VP3 capsid protein. In other embodiments, the rAAV particles contain the VP1 capsid protein, the VP2 capsid protein, and the VP3 capsid protein. In some embodiments, the rAAV particles contain the VP1 capsid protein, the VP2 capsid protein, and / or the VP3 capsid protein, and the capsid proteins of the rAAV particles have the same serotype. In other embodiments, the rAAV particles contain the VP1 capsid protein, the VP2 capsid protein, and the VP3 capsid protein, and the capsid proteins of the AAV particles have the same serotype.
[0262] In certain embodiments, the capsid protein is a mutant capsid protein. Compared to the corresponding reference capsid protein (e.g., a naturally occurring parental capsid protein, i.e., the capsid protein of which it originates), the mutant capsid protein may contain one or more mutations, such as amino acid substitutions, amino acid deletions, and heterologous peptide insertions. In some embodiments, the amino acid sequence of the AAV capsid protein is the same as that of the wild-type, reference, or parent AAV capsid protein, except for 1, 2, 3, 4, 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, or 30 amino acid residue substitutions, for example, 1, 2, 3, 4, 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, or 30 amino acid residue substitutions. In some embodiments, the capsid proteins or AAV particles described herein may be chimeric capsid proteins or AAV particles each comprising protein sequences of two or more AAV serotype capsid proteins or particles.
[0263] In various embodiments, the mutant AAV capsid proteins described herein are the capsid proteins of mutant AAV VP1. Furthermore, mutant AAV capsid proteins that are the VP2 and VP3 counterparts of the VP1 capsid protein described herein are described. Furthermore, fragments of such mutant AAV capsid proteins (e.g., fragments of the VP1, VP2, or VP3 capsid proteins) are described, which include, but are not limited to, variable regions (e.g., VR IV and VR VIII), GH loops, and functional fragments that substantially retain the corresponding capsid proteins and their associated tissue-targeting properties.

This can be achieved by incorporating a plasmid (or multiple plasmids) containing the AAV rep and cap genes and a selection marker (e.g., an antibiotic (e.g., neomycin or ampicillin) resistance gene) into the cell genome. The cell may be, for example, an insect or mammalian cell and may be co-infected with a helper virus (e.g., an adenovirus or baculovirus that provides helper function) and an rAAV vector containing 5' and 3' AAV ITRs. The use of a selection marker enables mass production of rAAV. Another non-limiting example is that, instead of a plasmid, an adenovirus or baculovirus may be used to introduce the rep and cap genes into the packaging cell. As another non-limiting example, viral vectors containing 5' and 3' AAV ITRs, along with rep and cap genes, can both be stably integrated into the DNA of producing cells, and helper functions can be provided by wild-type adenovirus to produce rAAV.
[0389] AAV helper viruses are viruses that enable AAV to be replicated and packaged by host cells. Helper viruses provide helper functions that allow AAV replication. Many such helper viruses have been identified, including adenoviruses, herpesviruses, and poxviruses such as cowpox. Adenoviruses encompass many different subgroups, but the most commonly used is adenovirus type 5 (Ad5) of subgroup C. Many adenoviruses of human, non-human mammalian, and avian origin are known and can be obtained from storage institutions such as ATCC. Herpesviridae viruses that can be obtained from depositary centers such as ATCC include, for example, herpes simplex virus (HSV), Epstein-Barr virus (EBV), cytomegalovirus (CMV), and herpesvirus (PRV). Examples of adenovirus helper functions for AAV replication include E1A, E1B, E2A, VA, and E4 or E6 functions.
[0390] If the ratio of infectious AAV particles to infectious helper virus particles is at least about 10²:1, at least about 10⁴:1, at least about 10⁶:1, or at least about 10⁸:1, the AAV preparation is considered substantially helper virus-free. The preparation does not need to contain an equal amount of helper virus protein (i.e., the protein present by this level of helper virus if the above-mentioned helper virus particle impurities are present in a disrupted form). Viral and / or cellular protein contamination is usually observed by the presence of Coomassie staining bands on the SDS gel (e.g., the appearance of bands other than those corresponding to AAV capsid proteins VP1, VP2, and VP3).
[0391] In certain embodiments, host cells containing the rAAV vector can produce rAAV particles by providing an AAV helper function in which the AAV ITR provides an AAV helper function for replicating and encapsulating a transgene encoding a protein of interest that has been flanked. The AAV helper function is typically an AAV-derived coding sequence which can be expressed to provide an AAV gene product which is further used in trans-action for productive AAV replication. In this specification, the AAV helper function is used to compensate for a required AAV function that is lost in the rAAV vector. In some embodiments, the AAV helper function includes one or both of the major AAV ORFs (i.e., rep and cap coding regions) or their functional homologs.
[0392] AAV helper function can be introduced into host cells by transfecting them with an AAV helper construct before or simultaneously with transfection with an rAAV vector. For example, an AAV helper construct can be used to compensate for the loss of AAV function necessary for productive AAV infection by providing transient expression of at least the AAV rep and / or cap genes. Typically, AAV helper constructs are lacking in AAV ITRs and cannot replicate or package. AAV helper constructs may be in the form of plasmids, phages, transposons, cosmids, viruses, or virions.
[0393] In certain embodiments, host cells may provide, or could be provided with, non-AAV-derived functions or “helper functions” for the production of rAAV particles. Helper functions are cellular functions on which non-AAV-derived viruses and / or AAVs depend for replication, and include, for example, non-AAV proteins and RNAs necessary for AAV replication, which are involved in activating AAV gene transcription, splicing step-specific AAV mRNA, AAV DNA replication, synthesis of Cap expression products, and packaging of AAV capsids. In some embodiments, virus-based helper functions may be derived from known helper viruses.
[0394] In some embodiments, recombinant AAV particles are produced as a result of infecting host cells with a helper virus and / or a helper functional vector, the produced rAAV particles being infectious replication-deficient viruses and comprising an AAV protein shell encapsulating a heterologous nucleotide sequence of interest with AAV ITRs flanked at both ends.
[0395] rAAV particles can be purified from host cells using purification methods known in the art, such as chromatography, CsCl gradients, and other methods described, for example, U.S. Patents 6,989,264 and 8,137,948, and WO 2010 / 148143. In some embodiments, known methods such as inactivating residual helper viruses by heating may be used.

[0446] measurement mRNA level analysis Changes in gene levels or expression can be measured using various methods known in this field.
[0447] For example, various methods for detecting or quantifying mRNA levels are known in this field. Exemplary methods include, but are not limited to, northern blotting, ribonuclease-protected assays, and PCR-based methods. The mRNA sequence of a gene can be used to prepare a probe complementary to at least a portion of the mRNA sequence. The mRNA in the sample can then be detected with the probe using any suitable measurement method, such as PCR-based methods, northern blotting, or dipstick measurements.
[0448] The measurement method can vary depending on the type of mRNA information desired. Exemplary methods include, but are not limited to, Northern blotting and PCR-based methods (e.g., qRT-PCR). Methods such as qRT-PCR can also accurately quantify the amount of mRNA in a sample.
[0449] The presence of mRNA in a sample can be determined using any suitable measurement platform. For example, the measurement may take the form of a measurement rod, membrane, tip, disk, test strip, filter, microbeads, slide, multiwell plate, or optical fiber. The measurement system may have a solid support to which nucleic acid corresponding to mRNA is attached. The solid support may include, for example, plastic, silicon, metal, resin, glass, membrane, particles, precipitate, gel, polymer, sheet, sphere, polysaccharide, capillary, film, plate, or glass slide. The measurement components can be prepared and packaged as a kit for detecting mRNA.
[0450] If necessary, labeled mRNAs may be prepared by labeling nucleic acids. Typically, samples can be labeled using methods known in this field (e.g., the use of DNA ligases or terminal transferases, or labeling of the RNA backbone). See, for example, Ausubel et al., Short Protocols in Molecular Biology (Wiley & Sons, 3rd ed. 1995); Sambrook et al., Molecular Cloning: A Laboratory Manual (Cold Spring Harbor, NY, 3rd ed. 2001). In some embodiments, samples are labeled with fluorescent markers. Examples of fluorescent dyes include xanthene dyes, fluorescein dyes (e.g., fluorescein isothiocyanate (FITC), 6-carboxyfluorescein (FAM), 6-carboxy-2',4',7',4,7-hexachlorofluorescein (HEX), 6-carboxy-4',5'-dichloro-2',7'-dimethoxyfluorescein (JOE)), rhodamine dyes (e.g., rhodamine 110 (R110), N,N,N',N'-tetramethyl-6-carboxyrhodamine (TAMRA), 6-carboxy-X-rhodamine (ROX), 5-carboxyrhodamine 6G (R6G5 or G5), 6-carboxyrhodamine 6G) This includes, but is not limited to, R6G6 or G6), cyanine dyes (e.g., Cy3, Cy5 and Cy7), Alexa dyes (e.g., Alexa-fluor-555), coumarin, diethylaminocoumarin, umbelliferone, benzimide dyes (e.g., Hoechst 33258), phenanthridine dyes (e.g., Texas Red), ethidium dyes, acridine dyes, carbazole dyes, phenoxazine dyes, porphyrin dyes, polymethine dyes, BODIPY dyes, quinoline dyes, pyrene, fluorescein chlorotriazinyl (Ctriazinyl), eosin dyes, tetramethylrhodamine, lisamin, naphthofluorescein, and others.
[0451] A typical mRNA assay may include the steps of: (1) obtaining a surface-bound subject probe; (2) hybridizing mRNA molecules to the surface-bound probe under conditions sufficient to provide specific binding; (3) washing after hybridization to remove nucleic acids that are not specifically bound to the surface-bound probe; and (4) detecting the hybridized mRNA. The reagents used in each of these steps and their usage conditions may vary depending on the specific application.
[0452] Hybridization can be carried out under appropriate hybridization conditions, where stringency may vary as desired. Typical conditions are sufficient to generate a probe / target complex on a solid surface between complementary binding members, i.e., between the target probe bound to the surface in the sample and complementary mRNA. In certain embodiments, stringent hybridization conditions may be employed.
[0453] Hybridization is typically performed under stringent hybridization conditions. Standard hybridization techniques (e.g., under conditions sufficient to result in specific binding of target mRNA in the sample to the probe) are described in Kallioniemi et al., Science 1992, 258:818-821 and International Publication No. 93 / 18186. Several guides to general techniques are available, e.g., Tijssen, Hybridization with Nucleic Acid Probes, Parts I and II (Elsevier Amsterdam 1993). For a description of techniques suitable for in situ hybridization, see Gall et al., Meth. Enzymol. 1981, 21:470-480; Angerer et al., Genetic Engineering: Principles and Methods, Vol 7, pgs 43-65 (Plenum Press, New York, Setlow and Hollaender, eds. 1985). The selection of appropriate conditions, including temperature, salt concentration, polynucleotide concentration, hybridization time, and stringency of washing conditions, depends on the experimental design, including the source of the sample, the type of capture agent (identity), and the expected degree of complementarity, and can be determined by those skilled in the art based on ordinary experiments.
[0454] Those skilled in the art will readily recognize that similar stringency conditions can be provided by utilizing alternative but equivalent hybridization and washing conditions.
[0455] After the mRNA hybridization procedure, surface-bound polynucleotides are generally washed to remove unbound nucleic acids. Washing can be performed using a stringent washing protocol, as described above. The hybridization of target mRNA to the probe is then detected using standard techniques.
[0456] Other methods, such as PCR-based methods, can also be used to detect gene expression. An example of a PCR method can be found in U.S. Patent No. 6,927,024, which is incorporated herein by reference in its entirety. An example of an RT-PCR method can be found in U.S. Patent No. 7,122,799, which is incorporated herein by reference in its entirety. A method for fluorescent in situ PCR is described in U.S. Patent No. 7,186,507, which is incorporated herein by reference in its entirety.
[0457] In some embodiments, quantitative reverse transcription PCR (qRT-PCR) can be used for both the detection and quantification of RNA targets (Bustin et al., Clin. Sci. 2005, 109:365-379). Quantitative results obtained by qRT-PCR generally provide more information than qualitative data. Therefore, in some embodiments, qRT-PCR-based assays may be useful for measuring mRNA levels during cell-based assays. The qRT-PCR method is also useful for monitoring patient treatment. An example of a qRT-PCR-based method can be found, for example, in U.S. Patent No. 7,101,663, which is incorporated herein by reference in its entirety.
[0458] In contrast to conventional reverse transcriptase-PCR and agarose gel analysis, qRT-PCR provides quantitative results. A further advantage of qRT-PCR is its relatively easy and convenient use. Instruments for qRT-PCR, such as the Applied Biosystems 7500, are commercially available, as are reagents such as TaqMan® Sequence Detection Chemistry. For example, TaqMan® gene expression assays can be used according to the manufacturer's instructions. These kits are pre-formulated gene expression assays for rapid and reliable detection and quantification of human, mouse, and rat mRNA transcripts. To determine the number of cycles at which the fluorescence signal associated with a particular amplicon accumulation crosses a threshold (called CT), data can be analyzed using, for example, the 7500 Real-Time PCR System Sequence Detection Software or the Comparative CT Relative Quantification Method. Using this method, the output is expressed as a multiplier change in expression level. In some embodiments, the threshold level can be selected to be automatically determined by the software. In some embodiments, the threshold level is set low enough to be above the baseline but within the exponential growth region of the amplification curve.
[0459] In other embodiments, the target RNA can be detected or quantified by next-generation sequencing (NGS).
[0460] Protein-level analysis Changes in protein expression levels can be assessed by measuring the level of the protein of interest. Protein levels can be evaluated or quantified by various methods known in the art, including immunoprecipitation, Western blot analysis (immunoblot), enzyme-linked immunosorbent assay (ELISA), quantitative protein assay, protein activity assay (e.g., caspase activity assay), immunohistochemistry, immunocytochemistry or fluorescence-activated cell sorting (FACS), LC-MS (liquid chromatography-mass spectrometry), and other methods. Antibodies against targets can be identified and obtained from various sources, such as the MSRS antibody catalog (Aerie Corporation, Birmingham, Mich.), or prepared by conventional monoclonal or polyclonal antibody production methods known in the art. Antibodies for detecting proteins of interest in mouse, rat, monkey, and human are commercially available. In the case of MassSpec, protein levels can be measured by labeled or unlabeled methods.
[0461] In-vivo analysis In vivo measurements can be used to evaluate the therapeutic effects of recombinant viral particles (including recombinant AAV particles, nonviral gene delivery systems, or pharmaceutical compositions as disclosed herein).
[0462] In some embodiments, motor function is measured by the animal's righting and open field performance. In certain embodiments, respiration is measured by whole-body plethysmography, invasive resistance, and compliance measurement within the animal's body.
[0463] In some embodiments, overall survival (OS) and disease-free survival (DFS) are measured by observing the body weight and health status of living animals twice a day.
[0464] The tests may be carried out in normal animals or experimental disease models. For administration to animals, oligonucleotides can be prepared in a pharmaceutically acceptable diluent, such as phosphate-buffered saline. Administration includes parenteral administration routes such as intraperitoneal, intravenous, and subcutaneous. The calculation of doses and administration frequencies of recombinant viral particles of this disclosure (including recombinant AAV particles, nonviral gene delivery systems, or pharmaceutical compositions) is within the scope of the skills of those skilled in the art and depends on factors such as the route of administration and animal body weight. After treatment with recombinant viral particles of this disclosure (including recombinant AAV particles, nonviral gene delivery systems, or pharmaceutical compositions) for a certain period of time, RNA or proteins can be isolated from tissues of interest, including liver, muscle, kidney, spleen, CNS tissue, or CSF, and changes in the expression of proteins of interest can be measured, for example, using NGS.

[0469] Examples Several embodiments provided herein, described by the following non-limiting examples, illustrate the design and testing of various human α-galactosidase A coding sequences, promoters, expression cassettes, and recombinant glandular virus (AAV) particles, demonstrating that they are particularly suitable for gene therapy, and especially for lysosomal storage disorders, including Fabry disease.
[0470] Example 1: Calibration of substrate levels in a mouse model of Fabry disease by intravenous administration of AAV-GLA. 1. Codon optimization of human α-galactosidase A (GLA). Two codon-optimized versions of the wild-type (WT) human GLA coding sequence (hGLAco1 and hGLAco2, each with nucleotide sequences corresponding to SEQ ID NO:1 and SEQ ID NO:2) were synthesized and cloned into an expression cassette backbone along with a chicken-β-actin (CB) promoter and a bovine growth hormone (bGH) poly A sequence. HepG2 cells were inoculated into 48-well plates (1e5 cells / well). Approximately 20 hours after inoculation, 500 ng plasmids expressing hGLA or GFP (negative control, Neg.ctrl) were transfected using Lipofectamine 3000. 72 hours after transfection, the supernatant was collected and centrifuged at 2,000 rpm for 10 minutes. GLA samples were diluted 100-fold or 1000-fold, and undiluted GFP samples were used in ELISA with the human α-galactosidase A ELISA pair kit (Cat. No. SEK12078) (Figure 1A). Samples were diluted 10-fold, and α-galactosidase A activity was measured using the kit (ab239716) (Figure 1B). 10 microliters of PNGase F-treated or untreated samples were used for Western blot analysis with an anti-α-galactosidase polyclonal antibody (1:1000, PA5-27349, Thermo Fisher) (Figure 1C). The PNGase F-treated pattern also demonstrated proper glycosylation of α-galactosidase A expressed from HepG2 cells. hGLAco1 showed twice as high protein expression as wild-type GLA. Therefore, hGLAco1 (SEQ ID NO: 1) was selected for further investigation.
[0471] 2. Hepatocyte-cardiomyocyte (HC) dual-specific promoter in in vitro studies. Five promoters (HC1-HC5, each containing nucleotide sequences corresponding to SEQ ID NO:4-8) were cloned upstream of the reniral luciferase (RLuc) reporter gene, including an immobilized 59-bp hepatocyte promoter (SEQ ID NO:3) linked to various cardiomyocyte-specific transcription factor binding sites (C1-C5). Firefly luciferase (FLuc), another reported gene driven by the HSV-TK promoter, resides on the same construct and is used as an internal control. Rat cardiomyocyte lineage H9c2 (ATCC) and HepG2 cells were inoculated into 96-well plates. One day after inoculation, plasmids containing promoters HC1-HC5 were transfected using Lipofectamine 3000. Two days after transfection, luminescence was quantified using a dual luciferase assay kit (Cat. No. E1500, Promega) and a SpectraMax i3x Multi-Mode Microplate Reader with a SpectraMax Injector Cartridge, according to the manufacturer's guidelines. The RLuc / FLuc ratio was used to measure HC promoter strength (Figure 2). RLuc, driven by the SV40 promoter, and FLuc, driven by the HSV-TK promoter, were used as positive controls (Pos.Ctrl). The HC1 promoter (SEQ ID NO:4) showed strong gene expression in both HepG2 and H9c2 (Figure 2). This was selected for in vivo studies.
[0472] 3. Severed mouse muscle creatine kinase (MCK) promoter in in vitro studies. Three MCK promoters (MCK-D1 to MCK-D3, each possessing nucleotide sequences from SEQ ID NO: 11 to 13) with 50-bp, 55-bp, and 105-bp cleavage forms derived from the CK8e promoter (SEQ ID NO: 14) were cloned upstream of the reniral luciferase (RLuc) reporter gene. C2C12 myoblasts were inoculated into 96-well plates. One day after inoculation, plasmids containing the MCK promoters were transfected using Lipofectamine 3000. Two days after transfection, luminescence was quantified using a dual luciferase assay kit (Cat. No. E1500, Promega) and a SpectraMax i3x Multi-Mode Microplate Reader with a SpectraMax Injector Cartridge. The RLuc / FLuc ratio was used to measure promoter strength (Figure 3A). RLuc plasmids driven by the CK8e promoter and FLuc plasmids driven by the HSV-TK promoter were used as controls. Compared to the CK8e promoter, cleavage at 50-bp, 55-bp, and 105-bp did not cause a decrease in activity (Figure 3A). The MCK-D3 promoter (SEQ ID NO. 13) was selected and used for further in vivo studies. A synthetic promoter HC7 (SEQ ID NO: 10) was constructed by combining the 59-bp hepatocyte promoter and the MCK-D3 promoter. The activity of promoter HC7 was evaluated using an in vivo imaging system (IVIS). Six-week-old BALB / c male mice were intravenously (tail vein) injected with AAV containing a firefly luciferase transgene driven by the HC7 promoter (1E11vg / mouse). Strong luminescence signals were observed in the liver and skeletal muscle one week (Figure 3B) and three weeks (Figure 3C) after injection.
[0473] 4. Expression and activity of α-galactosidase A mediated by a human GLA expression cassette in HepG2. Four constructs (Table 2) with different promoters or GLA variants were cloned into the autocomplementary adeno-associated virus (scAAV) vector backbone. HepG2 cells were inoculated into 48-well plates (1e5 cells / well). One day after inoculation, cells were transfected with 500 ng plasmids containing either the hGLA cassette (Table 2) or GFP (negative control, Neg.ctrl) using Lipofectamine 3000. Promoter HC6 (SEQ ID NO: 9) was constructed by combining a 59-bp hepatocyte promoter with a cleaved and modified human MCK promoter (SEQ ID NO: 15). Three days after transfection, the supernatant was collected and centrifuged at 2,000 rpm for 10 min. GLA samples were diluted 100-fold or 1000-fold, and undiluted samples from the GFP group were used in ELISA using a human α-galactosidase A ELISA pair kit (Cat. No. SEK12078) (Figure 4A). The samples were diluted 10-fold, and α-galactosidase A activity was measured using the kit (ab239716) (Figure 4B). thGLAco1: a cleaved form of human α-galactosidase A with two amino acids deleted from the C-terminus (nucleotide sequence shown in SEQ ID NO: 20). All constructs showed high expression and activity of α-galactosidase A protein in HepG2.
[0474] [Table 2]
[0475] 5. Expression and activity of α-galactosidase A mediated by a human GLA expression cassette in H9c2 cells. Four constructs (cassettes 1-4) were transfected into H9c2 cells using Lipofectamine 3000. A plasmid expressing GFP was used as a negative control. Three days after transfection, the supernatant was collected and used for human α-galactosidase A ELISA (Figure 5A) and activity analysis (Figure 5B). Construct cassette 3 showed 3.1-fold and 3.8-fold expression compared to cassettes 1 and 2, respectively (Figure 5A). Deletion of the last two amino acids resulted in a 1.4-fold decrease in α-galactosidase A activity in vitro (Figure 5B).
[0476] 6. In a mouse model of Fabry disease, the activity and effects mediated by cassette 1 were characterized. Expression cassette 1 was packaged into scAAV9. scAAV9 was produced by transfection of a triple plasmid and purified by iodoxanol gradient ultracentrifugation. The titer of the vector genome was measured by ddPCR and purity was confirmed by SDS-PAGE. The scAAV9 vector was filtered through 0.22 μm and adjusted to approximately 1E13 vg / mL in phosphate-buffered saline (PBS) with 0.001% Pluronic F68 (formulation buffer). Four groups of adult male GLA-KO mice (JAX stock #003535) were intravenously injected with scAAV9 containing the expression cassette 1 at four doses (2E11 vg / kg, 2E12 vg / kg, 6E12 vg / kg, 2E13 vg / kg) via the tail vein. Two groups of GLA-KO and wild-type mice were intravenously injected with formulation buffer as controls. Serum was collected every two weeks using K2-EDTA tubes and used for α-galactosidase A activity analysis. Stable expression of α-Gal A in serum persisted until the end of the mouse study (Figure 6A). On day 61, GLA-KO mice treated with scAAV9 cassette 1 showed 178-fold, 2360-fold, 7285-fold, and 18485-fold higher human α-Gal A activity in serum at doses of 2E11vg / kg, 2E12vg / kg, 6E12vg / kg, and 2E13vg / kg, respectively, compared to wild-type mice treated with buffer (Figure 6B). At the endpoint, mice were killed and perfused with cold PBS. Total RNA was isolated from the liver and heart. Total RNA treated with DNA polymerase I was used for reverse transcription (RT). Transformed cDNA was used for quantitative real-time PCR using hGLAco1-specific primers / probes. Mouse GAPDH primers / probes were used as a reference for normalization. hGLA transgene mRNA levels were clearly dose-dependent in the liver (Figure 6C). Higher hGLA transgene mRNA levels were observed in the heart in the high-dose groups (2E12vg / kg, 6E12vg / kg, 2E13vg / kg) compared to the low-dose group (2E11vg / kg) (Figure 6D). Genomic DNA was isolated from the liver and heart using the DNeasy Blood & Tissue Kit (Qiagen).AAV vector genome copies in these tissues were measured by droplet digital PCR (ddPCR) using hGLAco1 and mouse TFRC primers / probes (Figure 5). Vector genome copies showed dose-dependent effects in both liver (Figure 6E) and heart (Figure 6F). Approximately 15 mg of liver samples were lysed in RIPA buffer. The supernatant after centrifugation was either treated with PNGase F or left untreated. Western blotting was performed using 2 μg protein / sample loaded with an anti-α-galactosidase polyclonal antibody (1:2000, PA5-27349, Thermo Fisher). After treatment with scAAV9-cassette 1, Western blotting results showed strong human α-Gal A protein expression and appropriate glycosylation in hepatocytes (Figure 6G). Human α-Gal A protein was not detected in GLA-KO and wild-type mice treated with buffer. Degradation samples from the liver, heart, and kidney were used for α-Gal A activity analysis (Figure 6H). Compared to wild-type mice treated with buffer, GLA-KO mice treated with the lowest dose (2E11vg / kg) of scAAV9 cassette 1 showed 58-fold, 3-fold, and 0.8-fold α-Gal A activity in the liver, heart, and kidney, respectively. GLA-KO mice treated with 2E12vg / kg of scAAV9 cassette 1 showed 1378-fold, 119-fold, and 10-fold α-Gal A activity in the liver, heart, and kidney, respectively. GLA-KO mice treated with 6E12vg / kg of scAAV9 cassette 1 showed 3104-fold, 153-fold, and 24-fold α-Gal A activity in the liver, heart, and kidney, respectively. GLA-KO mice treated with 2E13vg / kg scAAV9 cassette 1 showed 5005-fold, 1215-fold, and 87-fold increases in α-Gal A activity in the liver, heart, and kidney, respectively.
[0477] Since lyso-Gb3 is a biomarker for Fabry disease, its substrate levels were quantified using liquid chromatography-tandem mass spectrometry (LC-MS / MS). Compared to GLA-KO mice treated with a solvent control, all GLA-KO mice treated with AAV showed significantly reduced serum lyso-Gb3 levels (Figure 6I). Treatment with 2E11 vg / kg of scAAV9-cassette 1 reduced lyso-Gb3 to 2.5% of that of GLA-KO control mice. Treatment with three higher doses (2E12, 6E12, and 2E13 vg / kg) completely restored serum lyso-Gb3 levels to normal (Figure 6I). Treatment with 2E12 vg / kg of scAAV9-cassette 1 completely restored lyso-Gb3 levels in the liver, heart, and kidneys to normal (Figure 6J).
[0478] 7. In a mouse model of Fabry disease, the activity and efficacy mediated by AAV-hGLA were characterized. Two expression cassettes (Cassette 1 and Cassette 3) were packaged with AAV9-derived liver-muscle oriented mutant AVT908. AAV production, purification, and characterization were the same as described above. Each hGLA expression cassette was intravenously injected into four groups of adult male GLA-KO mice (JAX stock #003535) via the tail vein at two doses (6E11vg / kg, 2E12vg / kg) (n=5 / group). Serum was collected every two weeks using K2-EDTA tubes and used to measure α-galactosidase A activity (Figure 7A). Eight weeks after treatment, α-Gal A activity in the serum of Cassette 3 was 134% of that of Cassette 1. Similar hGAL transgene mRNA levels were observed in the liver for both expression cassettes. In muscle tissue with similar or lesser vector genome copies (Figure 7B), Cassette 3 showed significantly higher hGLA transgene mRNA levels in the heart and quadriceps than Cassette 1 (Figure 7C). Similarly, for both doses, Cassette 3 showed 84-fold activity in the heart compared to Cassette 1. RT-qPCR data confirmed the activity of the hepatocyte-muscle bispecific promoter HC7 in both liver and muscle. Since mice were fully perfused with PBS before tissue sampling, the α-Gal A protein detected in the heart originated from and / or was taken up by cardiomyocytes. Western blotting revealed that higher doses of Cassette 3 resulted in even higher levels of α-Gal A protein in the heart (Figure 7D). Cassette 1 at a dose of 2E12vg / kg also showed the presence of α-Gal A protein in the heart. Mouse GAPDH was used as a control. Liver, heart, and kidney tissues were degraded and used for α-Gal A activity measurement. All tissues showed high activity after AAV-hGLA treatment. Administration of 2E12vg / kg of Cassette 3 resulted in α-Gal A activity in the liver, heart, and kidneys at 274%, 632%, and 189% of that of the 6E11vg / kg administration, respectively (Figure 7E). Compared to GLA-KO mice treated with buffer, immunohistochemical staining in the liver and heart of GLA-KO mice treated with 2E12vg / kg of Cassette 3 detected robust and widely expressed human α-Gal A protein in an AAV background (Figure 7F).The presence of human α-Gal A protein expressed by AAV in the kidney was also observed (Figure 7F).
[0479] Example 2: Calibration of substrate levels in a Fabry disease mouse model by intravenous administration of AAV-GLA Fabry disease (FD) is a rare X-linked metabolic disorder caused by a deficiency of the lysosomal enzyme α-galactosidase A (α-Gal A) resulting from pathogenic mutations in the GLA gene. The accumulation of substrates within lysosomes gradually leads to cellular dysfunction and multi-organ damage. While current enzyme replacement therapies are effective in treating FD, lifelong infusions every two weeks are a significant burden for patients. To provide a sustained-acting single dose, this study aims to develop a recombinant adeno-associated virus (rAAV) vector-based gene therapy for FD. Two algorithms were used to generate codon-optimized human GLA (hGLA) cDNA with minimal CpG. A series of synthetic hepatophile promoters were evaluated in vitro. Subsequently, an optimized transgene expression cassette was selected and packaged into AAV9 (scAAV9-hGLA). Single intravenous injection of scAAV9-hGLA into 10-week-old α-Gal A knockout male mice resulted in dose-dependent α-Gal A activity in the serum, liver, heart, and kidneys. Stable serum expression of α-Gal A persisted until the end of the 8-week mouse study. Compared to wild-type mice treated with a solvent control (buffer), the lowest dose (2 × 10⁶) showed significant improvement. 11 GLA-KO mice treated with vg / kg showed α-Gal A activity of 178x (×), 58×, 3×, and 0.8× in serum, liver, heart, and kidney, respectively. 2×10 12 GLA-KO mice treated with vg / kg scAAV9-hGLA showed α-Gal A activity of 2360×, 1378×, 119×, and 10×. The highest dose was (2×10⁻⁶). 13(vg / kg) resulted in an increase in serum α-Gal A activity to 18,485×. Since lyso-Gb3 is a biomarker for FD, substrate levels were quantified using liquid chromatography-tandem mass spectrometry (LC-MS / MS). Compared to GLA-KO mice treated with a solvent control, all GLA-KO mice treated with AAV showed significantly reduced serum lyso-Gb3 levels. 2×10 11 Treatment with scAAV9-hGLA at vg / kg reduced lyso-Gb3 to 2.5% of that in GLA-KO control mice. Three relatively high doses (2 × 10) were used. 12 , 6×10 12 and 2 × 10 13 Treatment with vg / kg restored lyso-Gb3 levels in serum, liver, heart, and kidney to normal levels. Codon-optimized hGLA transgene mRNA levels were associated with AAV vector genomic copies in the liver and showed dose-dependent effects. Western blotting demonstrated robust expression and proper glycosylation of liver-derived human α-Gal A protein. Immunostaining confirmed the presence of α-Gal A in the liver, heart, and kidney. Histopathological examination revealed no toxicity at any dose. Finally, this study demonstrated that the effective dose can be further minimized by using a newly developed, in-house developed liver-muscle-targeted capsid AVT908 and promoter. The data support the development of low-dose AAV-GLA gene therapy for Fabry disease.
[0480] Example 3: Robust hGLA expression in NHP mediated by an engineered AAV capsid Human GLA transgene expression cassette 3 (SEQ ID NO: 18) was packaged into capsids AAV9 (SEQ ID NO: 21), AVT917 (SEQ ID NO: 56), and AVT918 (SEQ ID NO: 58). All three AAVs were produced in HEK293 cells using a triple transfection method. After purification by affinity chromatography and filtration through 0.22 μm, the titer of the vector genome was determined by ddPCR using hGLA primers / probes. Purity was analyzed by SDS-PAGE. AAV products with endotoxin levels below 1 EU / mL were used in non-human primate (NHP) studies.
[0481] In three adult (>3 years old) male cynomolgus monkeys that did not have pre-existing neutralizing antibodies against AAV9, we compared in vivo hGLA expression mediated by different AAV capsids. Without the use of immunosuppressants, each animal was intravenously administered a single AAV expressing hGLA at a dose of 2E13vg / kg.
[0482] Eight weeks after administration, animals injected with AVT918 containing hGLA expression cassette 3 were killed. Plasma, liver, heart, kidney, and skeletal muscle were collected and processed for α-Gal A activity measurement.
[0483] Animals injected with AVT917 containing hGLA expression cassette 3 were killed 13 weeks after administration. Plasma, liver, heart, kidney, and skeletal muscle were collected, and α-Gal A activity was measured. Total genomic DNA was extracted from major tissues using the DNeasy Blood & Tissue Kit (Qiagen, 69506). AAV vector genomic copies in tissues were measured by ddPCR (Bio-Rad, QX200) using transgene hGLA-specific primers / probes (forward primer: forward: 5'-GGCAGCTTTGGCTACTATGA 3', reverse: 5'-GTCACAGTAGCAGCCATCAA 3', probe: 5'-FAM-TTGATGCCCAGACCTTTGCTGACT-BHQ1-3'). RNA polymerase P primer / probe (Thermo Fisher Scientific, 4403326) was used as a reference. To quantify transgene mRNA levels in tissue, total RNA was isolated using the TaKaRa MiniBEST Universal RNA Extraction Kit (Takara, 9767). cDNA was generated using the PrimeScript® RT Kit (Takara, RR047B) with a gDNA Eraser. hGLA primers / probes were used for transgene-specific transcripts. Macacu GAPDH (forward: 5'-GCACCGTGAAGGCTGAGAAC-3', reverse: 5'-GGATCTCGCTCCTGGAAGATG-3', probe: 5-HEX-CTCGTCATCAATGGAAGCCCCATCA-BHQ1-3') was used as a housekeeping gene. The relative transgene mRNA levels were 2 - Δ Ct It was calculated using the formula.
[0484] Animals injected with AAV9 containing hGLA expression cassette 3 were released after monitoring plasma α-Gal A activity for 26 weeks. From week 6 onward, plasma α-Gal A activity and human α-Gal A protein levels in these animals were stable (triangles in Figure 8). Long-term data over 26 weeks demonstrated that the HC7 promoter (SEQ ID NO: 10) has stable activity in NHP in the case of AAV.
[0485] Plasma and serum samples were collected at different time points. α-Gal A activity in plasma was measured using fluorescence-based enzyme activity assays. Specifically, 4-methylumbelliferone (4-MU) (Sigma-Aldrich, M1381-100G) was dissolved in DMSO and serially diluted as a standard. 4-MU-α-D-galactopyranoside (4-MU-α-Gal) (Cayman Chemical, 16551) was used as the substrate. Furthermore, N-acetylgalactosamine (Sigma-Aldrich, A2795-500MG), an α-galactosidase B inhibitor, was added to the samples. A black 96-well plate (Corning, 3603) was shaken at 100 rpm and incubated at 37°C for 2 hours. After incubation, 0.1 mL of 0.5 M glycine-NaOH buffer (pH 10.5) was added to each well to stop the reaction. Fluorescence intensity was measured using endpoint setting (Ex / Em = 365 / 450 nm). α-Gal A activity was calculated according to a 4MU calibration curve and expressed as nmol / h / mL plasma or nmol / h / mg protein.
[0486] All three capsids (AAV9, AVT917, and AVT918) mediated high levels of α-Gal A activity in NHP plasma after intravenous administration (Figure 8A). AVT917 mediated the highest level of α-Gal A activity in plasma, showing a 1,778-fold increase from baseline levels (Table). [Table 3]
[0487] All three capsids (AAV9, AVT917, and AVT918) mediated the expression of specific human α-Gal A protein in NHP plasma after intravenous administration (Figure 8B). AVT917 showed the highest GLA expression based on the concentration of human α-Gal A protein in plasma (Table). [Table 4]
[0488] AAV vector genome (vg) copies were measured in NHP tissue treated with AVT917 by ddPCR. Vector genome copies in the left and right lobes of the liver, heart, kidney, triceps, quadriceps, and calf were 990, 1126, 8.6, 0.7, 1.2, 1.6, and 2.0 vg / diploid genome (dpg), respectively. Vector genome copies in central nervous system (CNS) tissue were less than 1 vg / dpg (Figure 9A). The level and tissue specificity of transgene hGLA mRNA driven by the HC7 promoter (SEQ ID NO: 10) were evaluated by RT-qPCR. The HC7 promoter showed robust activity in the liver, followed by activity in the heart and skeletal muscle (Figure 9B). Weak promoter activity was observed in kidney and CNS tissues. High hGLA transgene expression and high levels of α-Gal A activity mediated by AVT917 capsid and HC7 promoter were monitored in plasma. Thirteen weeks after administration of AVT917 containing HC7-hGLA expression cassette 3, major tissues were collected and processed to measure α-Gal A activity. Compared to α-Gal A activity in tissues from animals not treated with AAV-hGLA (Neg Ctrl), improvements of approximately 80×, 54×, 1.6×, 197×, 68×, and 138× were observed in the heart, liver, kidney, gastrocnemius, quadriceps, and triceps muscles, respectively (Figure 9C).
[0489] Example 4: Efficacy of the capsid AVT917 containing HC7-hGLA in Fabry disease mice. Human GLA transgene expression cassette 3 (SEQ ID NO: 18) was packaged into capsid AVT917 (SEQ ID NO: 56) and produced in HEK293 cells by triple transfection. The purified AAV preparation is called AVT917-HC7-hGLA. To explore the minimum effective dose, adult (~16 weeks old) male Fabry disease mice (GIa-KO) were intravenously injected with three doses (2E11vg / kg, 6E11vg / kg, 2E12vg / kg, n=10 / group) of solvent (formulation buffer) or AVT919-HC7-hGLA (cassette 3). Plasma was collected every two weeks and used for α-Gal A activity measurement. Compared to solvent-group mice, all mice treated with AVT917-HC7-hGLA showed hyperphysiological α-Gal A activity in plasma over an 8-week study (Figure 10A). A dose-dependent increase in α-Gal A activity was observed in the AVT917-HC7-hGLA-treated group (Figure 10A). Eight weeks after treatment, the mean plasma α-Gal A activity levels in the solvent, low-dose (2E11vg / kg), medium-dose (6E11vg / kg), and high-dose (2E13vg / kg) mice were 1.37 nmol / h / mL, 2336.19 nmol / h / mL, 6140.66 nmol / h / mL, and 18189.11 nmol / h / mL, respectively, corresponding to improvements of 1×, 1710×, 4495×, and 13314× compared to the mean plasma α-Gal A activity levels in solvent-treated Fabry disease mice.
[0490] The levels of transgene hGLA mRNA in tissues of Fabry disease mice treated with AVT917-HC7-hGLA were evaluated by RT-qPCR. First, hGLA transcripts were present in the liver and heart (Figure 11A, B). Weak hGLA mRNA levels were observed in the quadriceps and gastrocnemius skeletal muscles (Figure 11D, E). Negligible transgene expression was observed in the kidneys and spleen (Figure 11C, F). These data support the in vivo hepatocyte-myocyte bispecific activity of the HC7 promoter.
[0491] After a single intravenous administration of AVT917-HC7-hGLA to Fabry disease mice, key tissues were collected 8 weeks later and processed using liquid chromatography and tandem mass spectrometry (LC-MS-MS) for measurement of the substrate Lyso-Gb3. All Fabry disease mice treated with AVT917-HC7-hGLA showed a significant reduction in substrate in plasma, liver, heart, and kidney compared to Fabry disease mice treated with the solvent (Figure 12). Fabry disease mice treated with a low dose (2E11vg / kg) of AVT917-HC7-hGLA retained only 2.13%, 4.16%, 0.89%, and 8.73% Lyso-Gb3 in plasma, liver, heart, and kidney compared to Fabry disease mice treated with the solvent (Figure 12). Lyso-Gb3 levels in the tissues of Fabry disease mice treated with the solvent were set to 100%.
[0492] Example 4: Expression of hGLA transgenes mediated by AVT917 in NHP Adult male cynomolgus monkeys were intravenously administered AVT917-HC7-hGLA at doses of 2E12vg / kg (N=3) and 6E12vg / kg (N=2). Plasma was collected, and α-Gal A activity was measured by fluorescence-based 4-MU assay. Before AAV administration, the mean α-Gal A activity of 5 animals was 15.6 nmol / h / L. One week after administration, α-Gal A activity increased by 234× and 711× from baseline levels at 2E12vg / kg and 6E12vg / kg, respectively. After week 6, α-Gal A activity in the plasma of the three animals treated with 2E12vg / kg remained stable (Figure 13A). The observation period for one animal was long, at 26 weeks. α-Gal A activity in the plasma of two animals treated with 6E12vg / kg was stable between weeks 2 and 6 (Figure 13A). Enzyme activity increased slightly after week 6 (Figure 13A). These data support the ability of low-dose AVT917-HC7-hGLA to provide hyperphysiological and stable α-Gal A activity in NHP after a single intravenous administration.
[0493] Human α-Gal A protein expressed from NHP treated with AVT917-HC7-hGLA was measured by ELISA. Prior to administration, no human α-Gal A protein was detected in the plasma. One week after treatment with AVT917-HC7-hGLA, three animals receiving a dose of 2E12vg / kg showed plasma levels of 53 ng / mL, 105 ng / mL, and 224 ng / mL of human α-Gal A. From week 2 onward, human α-Gal protein levels remained stable in these three animals (mean levels: 27-36 ng / mL) (Figure 13B). At week 26, one animal showed a plasma level of 63 ng / mL of human α-Gal A protein. These data demonstrate that HC7 can provide stable promoter activity in NHP. In week 1, two animals treated with 6E12vg / kg of AVT917-HC7-hGLA showed human α-Gal A levels of 192 ng / mL and 433 ng / mL in their plasma. The mean human α-Gal A protein levels at weeks 2 and 13 were 123 ng / mL and 111 ng / mL, respectively (Figure 13B).
[0494] Example 5: Comparison of hGLA transgene expression mediated by AVT917 and AVT919 in NHP Adult male cynomolgus monkeys were intravenously administered AVT917 or AVT919 containing cassette 3 (SEQ ID NO: 18) at a dose of 2E12 vg / kg (N=1 / capsid). Plasma was collected and used for ELISA to measure human α-Gal A protein concentration. Before AAV administration, the human α-Gal A level in plasma was 0 ng / mL. After 1 week of administration, AVT917 and AVT919 generated 224 ng / mL and 147 ng / mL of human α-Gal A in plasma, respectively (Figure 14). The plasma human α-Gal A level mediated by AVT917 was higher than that mediated by AVT919 (Figure 14).
