[0002] The content of the electronically submitted sequence listing (Name: 4525_119PC02_SequenceListing_ST26.xml; Size: 294,812 bytes; and Date of Creation: July 5, 2024), filed with the application, is incorporated herein by reference in its entirety.FIELD OF DISCLOSURE
[0003] The present disclosure pertains to the medical field and gene delivery, including AAV gene therapy for treating ocular pathologies.BACKGROUND
[0004] Ophthalmic pathologies significantly affect the quality of life of millions of people each year, and can lead to severe discomfort, impaired vision, or blindness.
[0005] The delivery of therapeutics to ophthalmic regions and the subsequent kinetics of such therapies to the appropriate location(s) within or near the eye are of great importance for the treatment of a variety of ophthalmic pathologies.
[0006] Drug delivery with minimal adverse effects and maximal efficacy to the target tissue is one of the biggest challenges faced during drug development. Due to the structural and metabolic properties of the ophthalmic regions, different methods of administration (i.e., topical, systemic, ocular, and periocular injections) can result in vastly different concentrations of the therapeutic delivered to the site of action, often making it a challenge to be within the therapeutic window. Thus, effectively engineering and delivering therapeutics to the ophthalmic tissues is a crucial step in developing successful therapies.
[0007] Topical instillation, the least invasive route of administration, is also one of the least efficacious, e.g., bioavailability of topical therapeutics is generally low and penetration into the cornea and conjunctival epithelium is inefficient.
[0008] Systemic delivery can be accomplished through oral administration in the form of a tablet or liquid consumable or through parenteral routes, such as intravenous, intramuscular, subcutaneous, and intradermal administration in an injectable form. Due to low ocular bioavailability and high systemic exposure, these methods are atypical for therapeutics delivery in ophthalmology. Systemic metabolism is another hurdle for systemic administration, and greatly reduces the concentration of therapeutics that can reach the ophthalmic region.
[0009] Intraocular administration includes the injection or implantation of a sterile solution or device within the eye via intravitreal, subretinal, or suprachoroidal delivery routes. Intravitreal and subretinal injections are common routes of administration for vector-based therapeutics that treat diseases within the eye.
[0010] Periocular delivery is another method to introduce therapeutics into an ophthalmic region. The sub-conjunctival space is the most commonly used in clinical practice, but the therapeutic bioavailability is typically poor. Upon sub -conjunctival injection, therapeutic bioavailability has been determined to be roughly similar to topical administration and much lower than intravitreal administration (Subrizi, A. et al., Design Principles of Ocular Drug Delivery Systems: Importance of Drug Payload, Release Rate, and Material Properties. Drug Discov. Today 2019, 24, 1446-1457).
[0011] There is a need for the development of delivery strategies to the ophthalmic region that allow efficient delivery of the vector-based therapeutic while minimizing the iatrogenic complications.BRIEF SUMMARY

Definitions
[0147] In order that the present disclosure can be more readily understood, certain terms are first defined. Additional definitions are set forth throughout the detailed disclosure.
[0148] It is to be noted that the term "a" or "an" entity refers to one or more of that entity; for example, "a nucleic acid sequence," is understood to represent one or more nucleic acid sequences, unless stated otherwise. As such, the terms "a" (or "an"), "one or more," and "at least one" can be used interchangeably herein.
[0149] Furthermore, "and / or", where used herein, is to be taken as specific disclosure of each of the two specified features or components with or without the other. Thus, the term "and / or" as used in a phrase such as "A and / or B" herein is intended to include "A and B," "A or B," "A" (alone), and "B" (alone). Likewise, the term "and / or" as used in a phrase such as "A, B, and / or C" is intended to encompass each of the following aspects: A, B, and C; A, B, or C; A or C; A or B; B or C; A and C; A and B; B and C; A (alone); B (alone); and C (alone).
[0150] Numerical values presented herein may be written out, or expressed in scientific notation, i.e. x * 1 Of, or scientific E notation xEy.
[0151] It is understood that wherever aspects are described herein with the language "comprising," otherwise analogous aspects described in terms of "consisting of and / or "consisting essentially of are also provided.
[0152] The term "about" is used herein to mean approximately, roughly, around, or in the regions of. When the term "about" is used in conjunction with a numerical range, it modifies that range by extending the boundaries above and below the numerical values set forth. In general, the term "about" can modify a numerical value above and below the stated value by a variance of, e.g., 10 percent, up or down (higher or lower).
[0153] The term "at least" prior to a number or series of numbers is understood to include the number adjacent to the term "at least," and all subsequent numbers or integers that could logically be included, as clear from context. For example, the number of nucleotides in a nucleic acid molecule must be an integer. For example, "at least 18 nucleotides of a 21- nucleotide nucleic acid molecule" means that 18, 19, 20, or 21 nucleotides have the indicated property. When at least is present before a series of numbers or a range, it isunderstood that "at least" can modify each of the numbers in the series or range. "At least" is also not limited to integers (e.g., "at least 5%" includes 5.0%, 5.1%, 5.18% without consideration of the number of significant figures).
[0154] As used herein, "no more than" or "less than" is understood as the value adjacent to the phrase and logical lower values or integers, as logical from context, to zero. When "no more than" is present before a series of numbers or a range, it is understood that "no more than" can modify each of the numbers in the series or range.
[0155] The term "derived from," as used herein, refers to a component that is isolated from or made using a specified molecule or organism, or information (e.g., amino acid or nucleic acid sequence) from the specified molecule or organism. For example, a nucleic acid sequence (e.g., an AAV vector) that is derived from a second nucleic acid sequence (e.g., another AAV vector) can include a nucleotide sequence that is identical or substantially similar to the nucleotide sequence of the second nucleic acid sequence. In the case of a polynucleotide disclosed herein, the derived species can be obtained by, for example, naturally occurring mutagenesis, artificial directed mutagenesis or artificial random mutagenesis.
[0156] The term "operably linked" means that a nucleic acid sequence (e.g., a coding region such as a gene of interest) and a regulatory sequence(s) (e.g., a promoter, an enhancer, or a silencer) are arranged in such a way as to permit gene expression when the appropriate molecules (e.g., transcriptional activator proteins) are bound to the regulatory sequence(s). In some aspects, where a regulatory nucleic acid sequence (e.g., a promoter, an enhancer, or a silencer) is operably linked, to a coding region, the coding region is "under transcriptional control" of the regulatory nucleic acid sequence. The term "operably inserted" means that a nucleic acid sequence of interest is positioned adjacent a regulatory nucleic acid sequence which directs transcription and translation of the nucleic acid sequence of interest (i.e., facilitates the production of, e.g., a polypeptide encoded by a DNA of interest).
[0157] "Percent (%) sequence identity" or "Percent (%) identity" with respect to a reference polynucleotide or polypeptide sequence is defined as the percentage of nucleic acids or amino acids in a candidate sequence that are identical to the nucleic acids or amino acids in the reference polynucleotide or polypeptide sequence, after aligning the sequences and introducing gaps, if necessary, to achieve the maximum percent sequence identity.Alignment for purposes of determining percent nucleic acid or amino acid sequence identity can be achieved in various ways that are within the capabilities of one of skill in the art, for example, using publicly available computer software such as BLAST, BLAST- 2, or Megalign software. Those skilled in the art can determine appropriate parameters for aligning sequences, including any algorithms needed to achieve maximal alignment over the full length of the sequences being compared. For example, percent sequence identity values can be generated using the sequence comparison computer program BLAST.
[0158] As used herein, the term "modified" refers to a changed state or structure of a molecule of the disclosure. Molecules can be modified in many ways including chemically, structurally, and functionally.
[0159] As used herein, the term "synthetic" means produced, prepared, and / or manufactured by the hand of man. Synthesis of polynucleotides or polypeptides or other molecules of the present disclosure can be chemical or enzymatic.
[0160] The terms "nucleic acid," "polynucleotide," and "oligonucleotide," are used interchangeably in the present application. These terms refer only to the primary structure of the molecule. Thus, these terms include double- and single-stranded DNA, as well as double- and single-stranded RNA. The terms "nucleic acid," "polynucleotide," and "oligonucleotide," as used herein, are defined, as generally understood by the skilled person, as a molecule comprising two or more covalently linked nucleosides. Such covalently bound nucleosides can also be referred to as nucleic acid molecules or oligomers. Polynucleotides can be made recombinantly, enzymatically, or synthetically, e.g., by solid-phase chemical synthesis followed by purification. When referring to a sequence of the polynucleotide or nucleic acid, reference is made to the sequence or order of nucleobase moieties, or modifications thereof, of the covalently linked nucleotides or nucleosides.
[0161] The term "mRNA" as used herein, refers to a single stranded RNA that encodes the amino acid sequence of one or more polypeptide chains.
[0162] A "coding sequence" or a sequence "encoding" a particular molecule (e.g., a therapeutic protein or peptide) is a nucleic acid that is transcribed (in the case of DNA) or translated (in the case of mRNA) into polypeptide, in vitro or in vivo, when operably linked to an appropriate regulatory sequence, such as a promoter. The boundaries of the coding sequence are determined by a start codon at the 5' (amino) terminus and a translation stopcodon at the 3' (carboxy) terminus. A coding sequence can include, but is not limited to, cDNA from prokaryotic or eukaryotic mRNA, genomic DNA sequences from prokaryotic or eukaryotic DNA, and synthetic DNA sequences. A transcription termination sequence will usually be located 3' to the coding sequence.
[0163] As used herein, the term "promoter" refers to a DNA sequence recognized by the machinery of a cell in vivo, or by a synthetic machinery in vitro, or in vivo by the synthetic machinery introduced into the cell, required to initiate the specific transcription of a gene. In some aspects, the term promoter is also meant to encompass those nucleic acid elements sufficient for promoter-dependent gene expression controllable for cell-type specific, tissue-specific or inducible by external signals or agents; such elements can be located in the 5' or 3' regions of the native gene. In some aspects, the promoter is a constitutive promoter, a cell-type specific promoter, or an inducible promoter.
[0164] As used herein, the term "regulatable promoter" is any promoter whose activity is affected by a cis or trans acting factor (e.g., an inducible promoter, such as an external signal or agent).
[0165] As used herein, the term "constitutive promoter" is any promoter that directs RNA production in many or all tissue / cell types at most times, e.g., the human CMV immediate early enhancer / promoter region that promotes constitutive expression of cloned DNA inserts in mammalian cells.
[0166] As used herein, the term "ubiquitous promoters" is any promoter that is strongly active in a wide range of cells, tissues and cell cycles.
[0167] As used herein, the term "bidirectional promoter" is the intergenic region between two divergent genes located on complementary strands of the DNA, which drives their coordinated transcription in opposite directions.
[0168] As used herein, the term "tissue-specific promoter", refers to a promoter that has activity only in certain cell types, i.e., drives the expression of the operably linked nucleotide sequence only in certain cell types.
[0169] As used herein, the term "enhancer" is a cis-acting element that stimulates transcription of a nucleic acid (e.g., gene). As used herein, the term "silencer" is a cis-acting element that inhibits transcription of a nucleic acid (e.g., gene). Enhancers can function (e.g., can be associated with a coding sequence) in either orientation, over distances of upto several kilobase pairs (kb) from the coding sequence and from a position downstream of a transcribed region.
[0170] As used herein, the term "termination signal sequence" can be any genetic element that causes RNA polymerase to terminate transcription, such as for example a polyadenylation signal sequence. A polyadenylation signal sequence is a recognition region necessary for endonuclease cleavage of an RNA transcript that is followed by the polyadenylation consensus sequence AATAAA. A polyadenylation signal sequence provides a "polyA site," i.e., a site on a RNA transcript to which adenine residues will be added by post-transcriptional polyadenylation.
[0171] As used herein, the term "internal ribosome entry site" or "IRES" refers to an element that promotes direct internal ribosome entry to the initiation codon, such as ATG, of a cistron (a protein encoding region), thereby leading to the cap-independent translation of the gene. See, e.g., Jackson R J et al., Trends Biochem Sci 15(12):477-83 (199); Jackson R J and Kaminski, A. RNA l(10):985-1000 (1995). "Under translational control of an IRES" as used herein means that translation is associated with the IRES and proceeds in a cap-independent manner.
[0172] As used herein, the terms "mutation" or "polymorphism," refer to any changing of the structure of a gene, resulting in a genetic variant (also called "mutant" or "polymorphic allele"). Genetic variants can occur in somatic cells or in cells of the germ line. Genetic variants that occur in the germ line can be transmitted to subsequent generations. Genetic variants can occur in coding or non-coding regions, and can be caused by the alternation of single base in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.
[0173] The term "antisense," as used herein, refers to a nucleic acid that is sufficiently complementary to all or a portion of a gene, primary transcript, or processed mRNA, so as to interfere with expression of the endogenous gene. "Complementary" polynucleotides are those that are capable of base pairing according to the standard Watson-Crick complementarity rules. Specifically, purines will base pair with pyrimidines to form a combination of guanine paired with cytosine (G:C) and adenine paired with either thymine (A:T) in the case of DNA, or adenine paired with uracil (A:U) in the case of RNA. It is understood that two polynucleotides can hybridize to each other even if they are notcompletely complementary to each other, provided that each has at least one region that is substantially complementary to the other.
[0174] The terms "antisense strand" and "guide strand" refer to the non-coding DNA strand of a gene. The antisense strand serves as the template for producing messenger RNA (mRNA), and, in the absence of any alteration in the transcription process, it is complementary to the transcribed mRNA. A nucleic acid molecule that includes a region that is substantially complementary to an mRNA, comprises a sequence substantially identical to the antisense strand, thus it has sufficient complementarity to the target mRNA sequence to direct target-specific silencing.
[0175] The terms "sense strand" and "passenger strand," as used herein, refer to the coding DNA strand of a gene. In the absence of any alteration in the transcription process, the sense strand comprises the same sequence of the transcribed mRNA (exception made for the T in the DNA being transcribed into U in the RNA). The antisense and sense strands hybridize to form a duplex structure.
[0176] The term "expression vector" or "expression construct" means any type of genetic construct containing a nucleic acid in which part or all of the nucleic acid encoding sequence is capable of being transcribed. In some aspects, the expression vector or construct can comprise an antibody expression cassette.
[0177] As used herein, the term "delivery vector" or "vector" refers to any vehicle for the cloning of and / or transfer of a nucleic acid into a host cell, such as a plasmid, phage, transposon, cosmid, chromosome, artificial chromosome, virus, virion, etc. A vector can be a replicon to which another nucleic acid segment can be attached so as to bring about the replication of the attached segment. A "replicon" refers to any genetic element (e.g., plasmid, phage, cosmid, chromosome, virus) that functions as an autonomous unit of replication in vivo, i.e., capable of replication under its own control. The term "delivery vector" or "vector" includes both viral and nonviral vehicles for introducing the nucleic acid into a cell in vitro, ex vivo or in vivo. A large number of vectors are known and used in the art including, for example, plasmids, modified eukaryotic viruses, or modified bacterial viruses. In some aspects, insertion of a polynucleotide into a suitable vector can be accomplished by ligating the appropriate polynucleotide fragments into a chosen vector that has complementary cohesive termini. Vectors can be engineered to encode selectable markers or reporters that provide for the selection or identification of cells that haveincorporated the vector. Expression of selectable markers or reporters allows identification and / or selection of host cells that incorporate and express other coding regions contained on the vector. Examples of selectable marker genes known and used in the art include: genes providing resistance to ampicillin, streptomycin, gentamycin, kanamycin, hygromycin, bialaphos herbicide, sulfonamide, and the like; and genes that are used as phenotypic markers, i.e., anthocyanin regulatory genes, isopentanyl transferase gene, and the like. Examples of reporters known and used in the art include: luciferase (Luc), green fluorescent protein (GFP), chloramphenicol acetyltransferase (CAT), P-galactosidase (LacZ), P-glucuronidase (Gus), and the like. Selectable markers can also be considered to be reporters. In some aspects, the delivery vector is selected from the group consisting of a viral vector (e.g., an AAV vector), a plasmid, a lipid, a protein particle, a bacterial vector, and a lysosome.
[0178] Some aspects of the disclosure are directed to biological vectors, which can include viruses, particularly attenuated and / or replication-deficient viruses.
[0179] A "viral vector" refers to a viral derived component that can be used to carry and / or deliver a payload (e.g., a nucleic acid sequence that comprises one or more polynucleotide regions encoding or comprising a molecule of interest, e.g., a protein, a peptide, and an oligonucleotide or a plurality thereof). Viral vectors can be used to deliver genetic materials into cells. Viral vectors can be modified for specific applications. In some aspects, the delivery vector of the disclosure is a viral vector selected from the group consisting of an adeno-associated viral (AAV) vector, an adenoviral vector, a lentiviral vector, or a retroviral vector.
[0180] The term "adeno-associated virus vector" or "AAV vector" or "adeno-associated viral vector" as used herein refers to any vector that comprises or derives from components of an adeno-associated vector and is suitable to infect mammalian cells, preferably human cells. In some aspects, the term AAV vector can designate an AAV-type viral particle or virion comprising a payload. The AAV vector can be derived from various serotypes, including combinations of serotypes (i.e., "pseudotyped" AAV) or from various genomes (e.g., single stranded or self-complementary). In some aspects, the pseudotype AAV includes AAV2 ITRs and capsids from other known AAV vectors (e.g., an AAV2 / 8 or AAV2 / 9, which are commonly referred to herein by their capsid serotype, e.g., AAV8 or AAV9, respectively). In addition, the AAV vector can be replication defective and / ortargeted. As used herein, the term "adeno-associated virus" (AAV), includes but is not limited to, AAV type 1, AAV type 2, AAV type 3 (including types 3 A and 3B), AAV type 4, AAV type 5, AAV type 6, AAV type 7, AAV type 8, AAV type 9, AAV type 10, AAV type 11, AAV type 12, AAV type 13, AAV14, AAV15, AAV16, AAVS3, AAVrh8, AAVrhlO, AAVrh.74, AAV type 9e, AAVrh.20, AAVrh.39, AAVrh.46, AAVrh.73, AAVrh.74, AAVhu.12, AAVhu.21, AAVhu.26, AAVhu.37, AAVhu.51, AAV.RHM4-1, AAV.Anc80, AAV.7m8, AAV.PHP.B, AAV.PHP.eB, AAV2.5, AAV2tYF, AAV.LK03, AAV.HSC1, AAV.HSC2, AAV.HSC3, AAV.HSC4, AAV.HSC5, AAV.HSC6, AAV.HSC7, AAV.HSC8, AAV.HSC9, AAV.HSC10, AAV.HSC11, AAV.HSC12, AAV.HSC13, AAV.HSC14, AAV.HSC15, AAV.HSC16, snake AAV, avian AAV, bovine AAV, canine AAV, equine AAV, ovine AAV, goat AAV, shrimp AAV, those AAV serotypes and clades disclosed by Gao et al. (J. Virol. 78:6381 (2004)) and Moris et al. (Virol. 33:375 (2004)), and any other AAV now known or later discovered. See, e.g., FIELDS et al. VIROLOGY, volume 2, chapter 69 (4th ed., Lippincott-Raven Publishers). In some aspects, an "AAV vector" includes a derivative of a known AAV vector. In some aspects, an "AAV vector" includes a modified or an artificial AAV vector. In some aspects, an AAV vector includes a hybrid vector (e.g., AAV-DJ, AAV-PHP.B, AAV2-ESGHGYF, AAVM41, AAV-LK03, AAV2-BR1, AAV587MTP, AAV-Anc80L65, AAV2-7m8, AAV2HBKO, AAV2YF, AAV6-RGD or AAV6.2). In some aspects, the terms "AAV genome" and "AAV vector" can be used interchangeably. In some aspects, the AAV vector is modified relative to the wild-type AAV serotype sequence. In some aspects, the modified AAV vector is a modified AAV6, e.g., an AAV6 vector comprising the RGD peptide (an AAV6-RGD vector) or an AAV6 vector comprising mutations of surface exposed tyrosine residues as described, for example, in Sayroo et al. Gene Ther. 2016 Jan; 23(1): 18-25. In some aspects, the AAV6-RGD vector further comprises modified amino acids corresponding to Y705, Y731, T492, and K531, (e.g., Y705, Y731F, T492V, and K531E; also referred to as AAV-RGD-Y705-731F+T492V+K531E).
[0181] As used herein, “self-complementary adeno-associated virus” or “scAAV” is a viral vector engineered from the naturally occurring AAV such that the coding region has been designed to form an intra-molecular double-stranded DNA template. Thus, upon infection of a cell with a scAAV, rather than waiting for cell-mediated synthesis of the second strand, the two complementary halves of scAAV will associate to form one double stranded DNA(dsDNA) unit that is ready for replication and transcription. In some aspects, the coding capacity found in a typical rAAV (e.g., about 4.7-6kb) is reduced in by about half in a scAAV (e.g., 2.4kb). In some aspects, the rAAV is a scAAV.
[0182] As used herein, a "recombinant AAV particle", "recombinant AAV vector", "rAAV particle", or "rAAV vector" refers to an AAV vector that comprises a capsid protein and a vector genome (or an AAV genome, e.g., at least one inverted terminal repeat (ITR) region) comprising at least one payload region (e.g., an expression cassette including a polynucleotide encoding a therapeutic agent). In some aspects, the "AAV vectors of the present disclosure" or "AAV vectors" refer to AAV vectors comprising a polynucleotide encoding an antibody (e.g., an anti-IGF-lR antibody, an anti-IL6 antibody, an anti-FcRn antibody, an anti-TSHR antibody, an anti -IL 11 antibody, an anti-IL6-R antibody, or an anti-ILl lR antibody) and a vector genome comprising a pair of AAV ITRs, e.g., encapsulated in an AAV particle.
[0183] As used herein, a "therapeutic agent" refers to a compound (e.g., a chemical compound), a peptide, a protein (e.g., an antibody), a lipid, a carbohydrate, a nucleic acid, or any other molecule or compound capable of treating, ameliorating, or reducing the symptoms of a disease, a disorder, a condition, or a syndrome, or otherwise having a beneficial effect, upon administration to a subject suffering from the disease, disorder, condition, or syndrome.
[0184] As used herein, the term "polypeptide" is intended to encompass a singular "polypeptide" as well as plural "polypeptides," and comprises any chain or chains of two or more amino acids. Thus, as used herein, a "peptide," a "peptide subunit," a "protein," an "amino acid chain," an "amino acid sequence," or any other term used to refer to a chain or chains of two or more amino acids, are included in the definition of a "polypeptide," even though each of these terms can have a more specific meaning. The term "polypeptide" can be used instead of, or interchangeably with any of these terms. The term further includes polypeptides that have undergone post-translational or post-synthesis modifications, for example, conjugation of a palmitoyl group, glycosylation, acetylation, phosphorylation, amidation, derivatization by known protecting / blocking groups, proteolytic cleavage, or modification by non-naturally occurring amino acids. The term "peptide," as used herein encompasses full length peptides and fragments, variants or derivatives thereof. A "peptide" as disclosed herein, can be part of a fusion polypeptide comprising additionalcomponents such as, e.g., an Fc domain or an albumin domain, to increase half-life. A peptide as described herein can also be derivatized in a number of different ways. A peptide described herein can comprise modifications including e.g., conjugation of a palmitoyl group.
[0185] The term "subunit" refers to a polypeptide that can assemble with another polypeptide to form a protein comprising two or more subunits (e.g., an immunoglobulin (Ig)). In some aspects, a delivery vector of the disclosure can include a coding region for each of the subunits. For example, a viral vector can include both the coding region for the Ig heavy chain (or the variable region of the Ig heavy chain) and the coding region for the Ig light chain (or the variable region of the Ig light chain).
[0186] The terms "transcriptional regulatory protein," "transcriptional regulatory factor," and "transcription factor" are used interchangeably herein, and refer to a nuclear protein that binds a DNA response element and thereby transcriptionally regulates the expression of an associated gene or genes. Transcriptional regulatory proteins generally bind directly to a DNA response element, however in some cases binding to DNA can be indirect by way of binding to another protein that in turn binds to, or is bound to a DNA response element.
[0187] The term "self-processing cleavage site" or "self-processing cleavage sequence," as used herein refers to a post-translational or co-translational processing cleavage site or sequence. Such a "self-processing cleavage" site or sequence refers to a DNA or amino acid sequence, exemplified herein by a 2A site, sequence or domain or a 2A-like site, sequence or domain. The term "self-processing peptide" is defined herein as the peptide expression product of the DNA sequence that encodes a self-processing cleavage site or sequence, which upon translation, mediates rapid intramolecular (cis) cleavage of a protein or polypeptide comprising the self-processing cleavage site to yield discrete mature protein or polypeptide products.
[0188] As used herein, the term "additional proteolytic cleavage site," refers to a sequence that is incorporated into an expression construct of the disclosure adjacent a self-processing cleavage site, such as a 2A or 2A like sequence, and provides a means to remove additional amino acids that remain following cleavage by the self-processing cleavage sequence. Exemplary 2A peptides include, but are not limited to, P2A, E2A, F2A, and T2A. Exemplary "additional proteolytic cleavage sites" are described herein and include, but arenot limited to, furin cleavage sites with the consensus sequence RXKRR or RXKR. Such furin cleavage sites can be cleaved by endogenous subtili sin-like proteases, such as furin and other serine proteases within the protein secretion pathway. In some aspects, other exemplary "additional proteolytic cleavage sites" can be used, as described in e.g., Lie et al., Sci Rep 7, 2193 (2017).
[0189] The terms "antibody" and "antibodies" refer to an immunoglobulin molecule that recognizes and specifically binds to a target, such as a protein, polypeptide, peptide, carbohydrate, polynucleotide, lipid, or combinations of the foregoing through at least one antigen recognition site within the variable region of the immunoglobulin molecule. As used herein, the term "antibody" encompasses intact polyclonal antibodies, intact monoclonal antibodies, chimeric antibodies, humanized antibodies, human antibodies, fusion proteins comprising an antibody, and any other modified immunoglobulin molecule so long as the antibodies exhibit the desired biological activity. An antibody can be of any the five major classes of immunoglobulins: IgA, IgD, IgE, IgG, and IgM, or subclasses (isotypes) thereof (e.g. IgGl, IgG2, IgG3, IgG4, IgAl and IgA2), based on the identity of their heavy-chain constant domains referred to as alpha, delta, epsilon, gamma, and mu, respectively. The different classes of immunoglobulins have different and well known subunit structures and three-dimensional configurations.
[0190] The term "immunoglobulin" is used herein to include antibodies, functional fragments thereof, Fabs, scFvs, single domain antibodies (e.g., nanobodies), DARTs, F(ab')2, BITEs, and immunoadhesins. These antibody fragments or artificial constructs can include a single chain antibody, a Fab fragment, a univalent antibody, a bivalent of multivalent antibody, or an immunoadhesin. The binding or neutralizing antibody construct can be a monoclonal antibody, a "humanized" antibody, a multivalent antibody, or another suitable construct. An "immunoglobulin molecule" is a protein containing the immunologically-active portions of an immunoglobulin heavy chain and immunoglobulin light chain covalently coupled together and capable of specifically combining with an antigen. Immunoglobulin molecules are of any type (e.g., IgG, IgE, IgM, IgD, IgA and IgY), class (e.g., IgGl, IgG2, IgG3, IgG4, IgAl and IgA2) or subclass. The terms "antibody" and "immunoglobulin" can be used interchangeably herein. An "immunoglobulin heavy chain" is a polypeptide that contains at least a portion of the antigen binding domain of an immunoglobulin and at least a portion of a variable region ofan immunoglobulin heavy chain. Thus, the immunoglobulin derived heavy chain has significant regions of amino acid sequence homology with a member of the immunoglobulin gene superfamily. For example, the heavy chain in a Fab fragment is an immunoglobulin-derived heavy chain. An "immunoglobulin light chain" is a polypeptide that contains at least a portion of the antigen binding domain of an immunoglobulin and at least a portion of the variable region. Thus, the immunoglobulin-derived light chain has significant regions of amino acid homology with a member of the immunoglobulin gene superfamily. An "immunoadhesin" is a chimeric, antibody-like molecule that combines the functional domain of a binding protein, usually a receptor, ligand, cell-adhesion molecule, or 1-2 immunoglobulin variable domains with immunoglobulin constant domains, usually including the hinge or GS linker and Fc regions. A "fragment antigen-binding" (Fab) fragment" is a region of an antibody that binds to antigens. It is composed of one constant and one variable domain of each of the heavy and the light chain. With respect to immunoglobulins or antibodies as described herein, each fragment of an immunoglobulin coding sequence can be derived from one or more sources, or synthesized. Suitable fragments can include the coding region for one or more of, e.g., a heavy chain, a light chain, and / or fragments thereof such as the constant or variable region of a heavy chain (CHI, CH2 and / or CH3) and / or or the constant or variable region of a light chain. Alternatively, variable regions of a heavy chain or light chain can be utilized. Where appropriate, these sequences can be modified from the "native" sequences from which they are derived, as described herein. As used herein, the term "immunoglobulin construct" refers to any of the above immunoglobulins or fragments thereof which are encoded by and included in the expression cassettes described herein. The immunoglobulin construct encoded by and included in the expression cassettes described herein can be in a combination comprising the immunoglobulin construct and viral vectors described herein.
[0191] The term "antibody fragment" refers to a portion of an intact antibody. An "antigenbinding fragment," "antigen-binding domain," or "antigen-binding region," refers to a portion of an intact antibody that binds to an antigen. An antigen-binding fragment can contain an antigen recognition site of an intact antibody (e.g., complementarity determining regions (CDRs) sufficient to bind antigen). Examples of antigen-binding fragments of antibodies include, but are not limited to Fab, Fab', F(ab')2, and Fv fragments, linear antibodies, and single chain antibodies (e.g., nanobodies). An antigen-binding fragment ofan antibody can be derived from any animal species, such as rodents (e.g., mouse, rat, or hamster) and humans or can be artificially produced.
[0192] The term "nanobody" or "nanobodies" or "single-domain antibody" or "sdAb" refers to a class of antigen-binding fragments that is a single chain immunoglobulin molecule consisting of a monomeric variable antibody domain, which recognizes and specifically binds to an antigen.
[0193] The term "monoclonal" antibody or antigen-binding fragment thereof refers to a homogeneous antibody or antigen-binding fragment population involved in the highly specific recognition and binding of a single antigenic determinant, or epitope. This is in contrast to polyclonal antibodies that typically include different antibodies directed against different antigenic determinants. The term "monoclonal" antibody or antigen-binding fragment thereof encompasses both intact and full-length monoclonal antibodies as well as antibody fragments (such as Fab, Fab', F(ab')2, Fv), single chain (scFv) mutants, fusion proteins comprising an antibody portion, and any other modified immunoglobulin molecule comprising an antigen recognition site. Furthermore, a "monoclonal" antibody or antigenbinding fragment thereof refers to such antibodies and antigen-binding fragments thereof made in any number of manners including but not limited to by hybridoma, phage selection, recombinant expression, and transgenic animals.
[0194] The term "fully human monoclonal antibody" as used herein, refers to a type of monoclonal antibodies. Monoclonal antibodies can be, but are not limited to, murine, chimeras, humanized, or fully human, depending on the amount of sequence derived from murine or human genome. Murine monoclonal antibodies comprise only murine-derived antibody-coding sequence. Chimeras monoclonal antibodies comprise both murine- and human-derived antibody-coding sequences. Humanized monoclonal antibodies are an extension of chimeras in which all regions of the murine antibody-coding sequence are replaced with human antibody-coding sequences, exception made for the CDR-coding sequences. Fully human monoclonal antibodies comprise only human antibody-coding sequences and have no murine antibody-coding sequence.
[0195] The term "vectorized antibody", as used herein, refers to a delivery vector (e.g., a viral vector) comprising the nucleotide sequence that encodes an antibody or a derivative thereof.
[0196] The term "bispecific" or "bifunctional antibody" or antigen-binding fragment thereof refers to an artificial hybrid antibody having two different heavy / light chain pairs and two different binding sites. Bispecific antibodies can be produced by a variety of methods including fusion of hybridomas or linking of Fab' fragments. See, e.g., Songsivilai & Lachmann, Clin. Exp. Immunol. 79:315-321 (1990); Kostelny et al., J. Immunol. 148, 1547-1553 (1992).
[0197] The term "multispecific antibody" refers to an antibody having specificities for two or more different epitopes, typically non-overlapping epitopes or an antibody that contains more than two distinct antigen-binding sites.
[0198] As used herein, the terms "variable region" or "variable domain" are used interchangeably and are common in the art. The variable region typically refers to a portion of an antibody, generally, a portion of a light or heavy chain, typically about the aminoterminal 110 to 120 amino acids or 110 to 125 amino acids in the mature heavy chain and about 90 to 115 amino acids in the mature light chain, which differ extensively in sequence among antibodies and are used in the binding and specificity of a particular antibody for its particular antigen. The variability in sequence is concentrated in those regions called complementarity determining regions (CDRs) while the more highly conserved regions in the variable domain are called framework regions (FR). Without wishing to be bound by any particular mechanism or theory, it is believed that the CDRs of the light and heavy chains are primarily responsible for the interaction and specificity of the antibody with antigen. In some aspects, the variable region is a human variable region. In some aspects, the variable region comprises rodent or murine CDRs and human framework regions (FRs). In some aspects, the variable region is a primate (e.g., non-human primate) variable region. In some aspects, the variable region comprises rodent or murine CDRs and primate (e.g., non-human primate) framework regions (FRs).
[0199] The terms "VL" and "VL domain" are used interchangeably to refer to the light chain variable region of an antibody.
[0200] The terms "VH" and "VH domain" are used interchangeably to refer to the heavy chain variable region of an antibody.
[0201] The VH and VL regions can be further subdivided into regions of hypervariability, termed complementarity determining regions (CDR), interspersed with regions that are more conserved, termed framework regions (FR). Each VH and VL is composed of threeCDRs and four FRs, arranged from amino-terminus to carboxy-terminus in the following order: FR1, CDR1, FR2, CDR2, FR3, CDR3, and FR4. The variable regions of the heavy and light chains contain a binding domain that interacts with an antigen. The constant regions of the antibodies can mediate the binding of the immunoglobulin to host tissues or factors, including various cells of the immune system (e.g., effector cells) and the first component (Clq) of the classical complement system.
[0202] The term "Kabat numbering" and like terms are recognized in the art and refer to a system of numbering amino acid residues in the heavy and light chain variable regions of an antibody or an antigen-binding fragment thereof. In certain aspects, CDRs can be determined according to the Kabat numbering system (see, e.g., Kabat EA & Wu TT (1971) Ann NY Acad Sci 190: 382-391 and Kabat EA et al., (1991) Sequences of Proteins of Immunological Interest, Fifth Edition, U.S. Department of Health and Human Services, NIH Publication No. 91-3242). Using the Kabat numbering system, CDRs within an antibody heavy chain molecule are typically present at amino acid positions 31 to 35, which optionally can include one or two additional amino acids, following 35 (referred to in the Kabat numbering scheme as 35A and 35B) (CDR1), amino acid positions 50 to 65 (CDR2), and amino acid positions 95 to 102 (CDR3). Using the Kabat numbering system, CDRs within an antibody light chain molecule are typically present at amino acid positions 24 to 34 (CDR1), amino acid positions 50 to 56 (CDR2), and amino acid positions 89 to 97 (CDR3). In some aspects, the CDRs of the antibodies described herein can be determined according to the Kabat numbering scheme.
[0203] The term "Chothia numbering" and like terms are recognized in the art and refer to a system of numbering amino acid residues in the heavy and light chain variable regions of an antibody or an antigen-binding fragment thereof. In certain aspects, CDRs can be determined according to the Chothia numbering system (see, e.g., Chothia C & Lesk AM (1987) J Mol Biol 196:901-17 and Chothia C et al., (1989 Nature 342:877-83). The term "IMGT® numbering" and like terms are recognized in the art and refer to a system of numbering amino acid residues in the heavy and light chain variable regions of an antibody or an antigen-binding fragment thereof. In certain aspects, CDRs can be determined according to the IMGT® numbering system (see, e.g., Lefranc M P, et al., (1997) Immunol Today 18:509 and Lefranc M P et al (2003) Dev Comp Immunol 27:55-77). In someaspects, the CDRs of the antibodies described herein can be determined according to the IMGT® numbering scheme.
[0204] As used herein, the term "constant region" or "constant domain" are interchangeable and have the meaning common in the art. The constant region is an antibody portion, e.g., a carboxyl terminal portion of a light and / or heavy chain which is not directly involved in binding of an antibody to antigen but which can exhibit various effector functions, such as interaction with the Fc receptor. The constant region of an immunoglobulin molecule generally has a more conserved amino acid sequence relative to an immunoglobulin variable domain. In certain aspects, an antibody or antigen-binding fragment comprises a constant region or portion thereof that is sufficient for antibody-dependent cell-mediated cytotoxicity (ADCC).
[0205] As used herein, the term "heavy chain" when used in reference to an antibody can refer to any distinct type, e.g., alpha (a), delta (5), epsilon (a), gamma (y), and mu (p), based on the amino acid sequence of the constant domain, which give rise to IgA, IgD, IgE, IgG, and IgM classes of antibodies, respectively, including subclasses of IgG, e.g., IgGl, IgG2, IgG3, and IgG4. Heavy chain amino acid sequences are well known in the art. In some aspects, the heavy chain is a human heavy chain.
[0206] As used herein, the term "light chain" when used in reference to an antibody can refer to any distinct type, e.g., kappa (K) or lambda (X) based on the amino acid sequence of the constant domains. Light chain amino acid sequences are well known in the art. In some aspects, the light chain is a human light chain.
[0207] An "Fc region" (fragment crystallizable region) or "Fc domain" or "Fc" refers to the C- terminal region of the heavy chain of an antibody that mediates the binding of the immunoglobulin to host tissues or factors, including binding to Fc receptors located on various cells of the immune system (e.g., effector cells) or to the first component (Clq) of the classical complement system.
[0208] A "native sequence Fc region" or "native sequence Fc" comprises an amino acid sequence that is identical to the amino acid sequence of an Fc region found in nature. Native sequence human Fc regions include a native sequence human IgGl Fc region; native sequence human IgG2 Fc region; native sequence human IgG3 Fc region; and native sequence human IgG4 Fc region as well as naturally-occurring variants thereof. Nativesequence Fc includes the various allotypes of Fc (see, e.g., Jefferis et al., (2009) mAbs 1 : 1; Vidarsson G. et al. Front Immunol. 5:520 (published online Oct. 20, 2014)).
[0209] An "Fc receptor" or "FcR" is a receptor that binds to the Fc region of an immunoglobulin. FcRs that bind to an IgG antibody comprise receptors of the FcyR family, including allelic variants and alternatively spliced forms of these receptors. The FcyR family consists of three activating (FcyRI, FcyRIII, and FcyRIV in mice; FcyRIA, FcyRIIA, and FcyRIIIA in humans) and one inhibitory (FcyRIIB) receptor. Human IgGl binds to most human Fc receptors and elicits the strongest Fc effector functions. It is considered equivalent to murine IgG2a with respect to their types of activating Fc receptors that it binds to. Conversely, human IgG4 elicits the least Fc effector functions. (Vidarsson G. et al. Front Immunol. 5:520 (published online Oct. 20, 2014)). An "Fc effector function" refers to the interaction of an antibody Fc region with an Fc receptor or ligand, or a biochemical event that results therefrom.
[0210] The constant region can be manipulated, e.g., by recombinant DNA technology, to eliminate one or more effector functions. An "effector function" refers to the interaction of an antibody Fc region with an Fc receptor or ligand, or a biochemical event that results therefrom. Exemplary "effector functions" include Clq binding, complement dependent cytotoxicity (CDC), Fc receptor binding, FcyR-mediated effector functions such as ADCC and antibody dependent cell-mediated phagocytosis (ADCP), and down regulation of a cell surface receptor (e.g., the B cell receptor; BCR). Such effector functions generally require the Fc region to be combined with a binding domain (e.g., an antibody variable domain). Accordingly, the term "a constant region without the Fc function" include constant regions with reduced or without one or more effector functions mediated by Fc region. Additionally, the constant region can be manipulated, e.g., by recombinant DNA technology, to increase the antibody specificity, to improve the antibody's activity, to increase the antibody's half-life, to eliminate or reduce off target effects, or any combination thereof. As used herein, the term "antibody's half-life" refers to the time required for half the quantity of the antibody deposited in a living organism to be metabolized or eliminated by normal biological processes.
[0211] Effector functions of an antibody can be reduced or avoided by different approaches. Effector functions of an antibody can be reduced or avoided by using antibody fragments lacking the Fc region (e.g., such as a Fab, F(ab')2, single chain Fv (scFv), or asdAb consisting of a monomeric VH or VL domain). Alternatively, the so-called aglycosylated antibodies can be generated by removing sugars that are linked to particular residues in the Fc region to reduce the effector functions of an antibody while retaining other valuable attributes of the Fc region (e.g., prolonged half-life and heterodimerization). Aglycosylated antibodies can be generated by, for example, deleting or altering the residue the sugar is attached to, removing the sugars enzymatically, producing the antibody in cells cultured in the presence of a glycosylation inhibitor, or by expressing the antibody in cells unable to glycosylate proteins (e.g., bacterial host cells). See, e.g., U.S. Pub. No. 20120100140. Another approach is to employ Fc regions from an IgG subclass that have reduced effector function. For example, IgG2 and IgG4 antibodies are characterized by having lower levels of Fc effector functions than IgGl and IgG3. The residues most proximal to the hinge region in the CH2 domain of the Fc part are responsible for effector functions of antibodies as it contains a largely overlapping binding site for Clq (complement) and IgG-Fc receptors (FcyR) on effector cells of the innate immune system. Vidarsson G. et al. Front Immunol. 5:520 (published online Oct. 20, 2014). Accordingly, antibodies with reduced or without Fc effector functions can be prepared by generating, e.g., a chimeric Fc region which comprises a CH2 domain from an IgG antibody of the IgG4 isotype and a CH3 domain from an IgG antibody of the IgGl isotype, or a chimeric Fc region which comprises hinge region from IgG2 and CH2 region from IgG4 (see, e.g., Lau C. et al. J. Immunol. 191 :4769-4777 (2013)), or an Fc region with mutations that result in altered Fc effector functions, e.g., reduced or no Fc functions. Such Fc regions with mutations are known in the art. See, e.g., U.S. Pub. No. 20120100140 and U.S. and PCT applications cited therein and An et al., mAbs 1 :6, 572-579 (2009); the disclosures of which are incorporated by reference to their entirety.
[0212] In some aspects, the antibody (e.g., a monoclonal antibody) or antigen-binding fragment thereof is modified so that it does not bind to the Fc region. See e.g., Saunders K., Front. Immunol., 10: 1296 (2019).
[0213] A "hinge," "hinge domain," "hinge region," or "antibody hinge region" are used interchangeably and refer to the domain of a heavy chain constant region that joins the CHI domain to the CH2 domain and includes the upper, middle, and lower fragments of the hinge (Roux et al., J. Immunol. 1998 161 :4083). The hinge provides varying levels offlexibility between the binding and effector regions of an antibody and also provides sites for intermolecular disulfide bonding between the two heavy chain constant regions.
[0214] As used herein, "isotype" refers to the antibody class (e.g., IgGl, IgG2, IgG3, IgG4, IgM, IgAl, IgA2, IgD, and IgE antibody) that is encoded by the heavy chain constant region genes.
[0215] The phrases "an antibody recognizing an antigen" and "an antibody specific for an antigen" are used interchangeably herein with the term "an antibody which binds specifically to an antigen."
[0216] An "isolated antibody," as used herein, is intended to refer to an antibody which is substantially free of other antibodies having different antigenic. An isolated antibody that specifically binds to an epitope of a protein can, however, have cross-reactivity to other corresponding proteins from different species.
[0217] In some aspects, the antibody (e.g., a monoclonal antibody) or antigen-binding fragment thereof is a chimeric antibody. The term "chimeric" antibodies or antigen-binding fragments thereof refers to antibodies or antigen-binding fragments thereof wherein the amino acid sequence is derived from two or more species. Typically, the variable region of both light and heavy chains corresponds to the variable region of antibodies or antigenbinding fragments thereof derived from one species of mammals (e.g. mouse, rat, rabbit, etc.) with the desired specificity, affinity, and capability while the constant regions are homologous to the sequences in antibodies or antigen-binding fragments thereof derived from another (usually human) to avoid eliciting an immune response in that species.
[0218] In some aspects, the antibody (e.g., a monoclonal antibody) or antigen-binding fragment thereof is a humanized antibody. The term "humanized" antibody or antigenbinding fragment thereof refers to forms of non-human (e.g. murine) antibodies or antigenbinding fragments that are specific immunoglobulin chains, chimeric immunoglobulins, or fragments thereof that contain minimal non-human (e.g., murine) sequences. Typically, humanized antibodies or antigen-binding fragments thereof are human immunoglobulins in which residues from the complementarity determining regions (CDRs) are replaced by residues from the CDRs of a non-human species (e.g. mouse, rat, rabbit, hamster) that have the desired specificity, affinity, and capability ("CDR grafted") (Jones et al., Nature 321 :522-525 (1986); Riechmann et al., Nature 332:323-327 (1988); Verhoeyen et al., Science 239: 1534-1536 (1988)). In some aspects, a humanized antibody or antigen-bindingfragment thereof can comprise at least a portion of an immunoglobulin constant region or domain (Fc), typically that of a human immunoglobulin. Examples of methods used to generate humanized antibodies are described in U.S. Pat. 5,225,539; Roguska et al., Proc. Natl. Acad. Sci., USA, 91(3):969-973 (1994), and Roguska et al., Protein Eng. 9(10):895- 904 (1996). In some aspects, a "humanized antibody" is a resurfaced antibody.
[0219] In some aspects, the antibody (e.g., a monoclonal antibody) or antigen-binding fragment thereof is a human antibody. The term "human" antibody (HuMAb) or antigenbinding fragment thereof means an antibody or antigen-binding fragment thereof having an amino acid sequence derived from a human immunoglobulin gene locus, where such antibody or antigen-binding fragment is made using any technique known in the art. This definition of a human antibody or antigen-binding fragment thereof includes intact or full- length antibodies and fragments thereof.
[0220] As used herein, an "epitope" is a term in the art and refers to a localized region of an antigen to which an antibody or antigen-binding fragment thereof can specifically bind. An epitope can be, for example, contiguous amino acids of a polypeptide (linear or contiguous epitope) or an epitope can, for example, come together from two or more noncontiguous regions of a polypeptide or polypeptides (conformational, non-linear, discontinuous, or non-contiguous epitope. The term "epitope mapping" refers to the process of identification of the molecular determinants for antibody-antigen recognition.
[0221] As used herein, the term "functional fragment thereof' refers to a fragment or portion of a protein, e.g., an immunomodulatory protein, which is still capable of one or functions associated with the full protein (e.g., stimulating, modulating, regulating, or modifying an immune response).
[0222] As used herein, the term "inhibitor" refers to any agent that reduces the level and / or activity of a protein. Non-limiting examples of inhibitors include blocking antibodies, inhibitory proteins, dsRNA (e.g., siRNA or shRNA), and vectors, e.g., AAV, comprising polynucleotides encoding blocking antibodies, inhibitory proteins, or dsRNA (e.g., siRNA or shRNA). The term "reducing," as used herein, is used interchangeably with "silencing," "downregulating," "suppressing," and other similar terms, and includes any level of reduction.
[0223] As used herein, a "blocking antibody" is an antibody that does not have a reaction when combined with an antigen, but prevents other antibodies from combining with that antigen.
[0224] An antibody that is "blocking" or that "blocks" or that is "inhibitory" of that "inhibits" is an antibody that reduces or inhibits (partially or completely) binding of its target protein to one or more ligands when the antibody is bound to the target protein, and / or that reduces or inhibits (partially or completely) one or more activities or functions of the target protein when the antibody is bound to the target protein.
[0225] As used herein, the term "signal peptide," refers to a polypeptide sequence or combination of sequences that are sufficient to mediate the translocation of a polypeptide to the cell surface. Without being bound by any particular theory, translocation of a polypeptide to the cell surface can be mediated by the secretory pathway, including the translocation of a polypeptide from the cytosol to the endoplasmic reticulum, and the subsequent transport of the polypeptide through the Golgi, and to the cell membrane, where the protein can remain embedded in the cell membrane, or be secreted from the cell. As used herein, "signal peptides," include naturally-occurring and synthetic signal sequences, signal "patches" and the like. Examples of signal peptides include, but are not limited to, the endogenous signal peptide for HGH and variants thereof; the endogenous signal peptide for interferons and variants thereof, including the signal peptide of type I, II and III interferons and variants thereof; and the endogenous signal peptides for known cytokines and variants thereof, such as the signal peptide of erythropoietin (EPO), insulin, TGF-pi, TNF, ILl-a, and IL1-P, and variants thereof. In some aspects, the signal peptide is an IL-2 signal peptide. In some aspects, the signal peptide is an IL- 10 signal peptide. In some aspects, the signal peptide is a modified signal peptide.
[0226] The phrase "contacting a cell" (e.g., contacting a cell with a construct, a rAAV vector or pharmaceutical composition of the disclosure) as used herein, includes contacting a cell directly or indirectly. In some aspects, contacting a cell with a construct, a rAAV vector, or pharmaceutical composition of the disclosure includes contacting a cell in vitro or contacting a cell in vivo with the construct, rAAV vector, or pharmaceutical composition. Thus, for example, the construct, rAAV vector, or pharmaceutical composition can be put into physical contact with the cell by the individual performing the method, or alternatively,the construct, rAAV vector, or pharmaceutical composition can be put into a situation that will permit or cause it to subsequently come into contact with the cell.
[0227] In some aspects, contacting a cell in vitro can be done, for example, by incubating the cell with the construct or the AAV vector.
[0228] In some aspects, contacting a cell in vivo can be done, for example, by injecting a construct, a rAAV vector, or a pharmaceutical composition of the disclosure into or near the tissue where the cell is located (e.g., the ophthalmic region), or by injecting the construct, rAAV vector, or pharmaceutical composition into another area, e.g., the bloodstream or the subcutaneous space, such that the agent will subsequently reach the tissue where the cell to be contacted is located. For example, the AAV vector can be encapsulated and / or coupled to a ligand that directs the AAV vector to a site of interest. Combinations of in vitro and in vivo methods of contacting are also possible. For example, a cell can be contacted in vitro with a construct, a rAAV vector, or a pharmaceutical composition and subsequently transplanted into a subject.
[0229] In some aspects, contacting a cell with a construct, a rAAV vector, or a pharmaceutical composition of the present disclosure includes "introducing" or "delivering" (directly or indirectly) the construct, rAAV vector, or a pharmaceutical composition into the cell by facilitating or effecting uptake or absorption into the cell. In some aspects, introduction into a cell includes a method know in the art such as electroporation and lipofection.
[0230] As used herein, the term "in vitro" refers to events that occur in an artificial environment, e.g., in a test tube or reaction vessel, in cell culture, in a Petri dish, etc., rather than within an organism (e.g., animal, plant, or microbe).
[0231] As used herein, the term "in vivo" refers to events that occur within an organism (e.g., animal, plant, or microbe or cell or tissue thereof).
[0232] As used herein, the term "transfection" refers to methods to introduce exogenous nucleic acids into a cell by non-viral methods. Methods of transfection include, but are not limited to, chemical methods, physical treatments and cationic lipids or mixtures.

In some aspects, a therapeutically effective amount of an agent (e.g., a construct, a rAAV vector, or a pharmaceutical composition disclosed herein) is an amount that results in a beneficial or desired result in a subject as compared to a control.
[0238] The amount of a given agent (e.g., a construct, a rAAV vector, or a pharmaceutical composition disclosed herein) will correspond to such an amount will vary depending upon various factors, such as the given agent, the pharmaceutical formulation, the route of administration, the type of disease or disorder, the identity of the subject (e.g., age, sex, and / or weight) or host being treated, and the like.
[0239] The term "prophylactically effective amount," as used herein, includes the amount of an agent, (e.g., a construct, a rAAV vector, or a pharmaceutical composition disclosed herein) that, when administered to a subject having or predisposed to have a disease, disorder, syndrome, or condition (e.g., an ophthalmic disease, disorder, syndrome, or condition) is sufficient to prevent, reduce the symptoms of, or ameliorate the disease, disorder, syndrome, or condition or one or more symptoms of the disease, disorder, syndrome, or condition. Ameliorating the disease, disorder, syndrome, or condition includes slowing the course of the disease, disorder, syndrome, or condition, or reducing the severity of later-developing disease, disorder, syndrome, or condition. The "prophylactically effective amount" can vary depending on the characteristics of the agent, e.g., a construct, a rAAV vector, or pharmaceutical composition of the disclosure, how the agent is administered, the degree of risk of disease, and the history, age, weight, family history, genetic makeup, the types of preceding or concomitant treatments, if any, and other individual characteristics of the patient to be treated.

"Modulating," "regulating," or "modifying" an immune response refers to any alteration in a cell of the immune system or in the activity of such cell (e.g., an effector T cell). Such modulation includes stimulation or suppression of the immune system, which can be manifested by an increase or decrease in the number of various cell types, an increase or decrease in the activity of these cells, or any other changes, which can occur within the immune system. Both inhibitory and stimulatory immunomodulators have been identified, some of which can have enhanced function in a tumor microenvironment. In some aspects, the immunomodulator is located on the surface of a T cell. An "immunomodulatory target" or "immunoregulatory target" is an immunomodulator that is targeted for binding by, and whose activity is altered by the binding of, a substance, agent, moiety, compound or molecule. Immunomodulatory targets can include, for example, receptors on the surface of a cell ("immunomodulatory receptors") and receptor ligands ("immunomodulatory ligands").

[0300] Retrobulbar Administration
[0301] Certain aspects of the disclosure are directed to retrobulbar delivery of a therapeutic agent.
[0302] In some aspects, the retrobulbar delivery is a retrobulbar injection (see, e.g., FIG. 1).
[0303] In some aspects, the retrobulbar injection comprises (i) advancing a needle along the inferotemporal wall of the orbit (e.g., the needle is about parallel to the floor of the orbit with an inclination of 10 to 15 degrees), Approximately 1 cm after penetrating the orbital septum, posterior to the equator often felt as a "pop", the needle is redirected 30 to 45 degrees superonasal and advanced 2.5 to 3.5 cm until the intraconal space (e.g., aao.org / education / basic-skills / orbital-block-technique).
[0304] In some aspects, the retrobulbar injection comprises (i) advancing a needle along the inferotemporal wall of the orbit (e.g., the needle is about parallel to the floor of the orbit and angled down), (ii) redirecting needle upward and nasally toward the apex of the orbit, and (iii) advancing the needle until it penetrates the muscle cone. In some aspects, advancing the needle along the inferotemporal wall of the orbit comprises passing the needle through the junction of the middle and outer third of the inferior orbital rim and below the eye.
[0305] In some aspects, the retrobulbar injection is performed with a straight or curved needle. In some aspects, the retrobulbar injection is advanced to a depth of about 30 mm to about 35 mm, or to the region behind the globe.
[0306] In some aspects, the retrobulbar injection delivers a volume of about 5 mL to about10 mL.
[0307] In some aspects, the retrobulbar injection is within the lateral extraocular muscle cone.
[0308] Subtenon Administration
[0309] Certain aspects of the disclosure are directed to subtenon delivery of a therapeutic agent (e.g., administration of an AAV construct to a location that is between the capsule and the sclera, also known as the episcleral space).
[0310] In some aspects, the subtenon delivery is a subtenon injection.
[0311] In some aspects, a small tent of the conjunctiva and Tenon capsule is raised with a pair of blunt, non-toothed forceps approximately 5-10 mm from the inferio-nasal limbus and can be as far inferior as the fornix depending on patient anatomy; a small incision is made in the tissue using a pair of ophthalmic scissors, exposing the sclera below; the blunt ended sub-Tenon's cannula can then be inserted through the newly created defect, with the syringe of the AAV construct attached, and passed posteriorly, following the curvature of the globe, until its tip is perceived to passed the equator - making sure to insert the cannula in the subtenons space (just exterior to bare sclera) and not in the subconjunctival space; the AAV construct is then injected. See, e.g., Amin S, et al., A new technique for delivering sub-Tenon anaesthesia in ophthalmic surgery. Br J Ophthalmol; 2001; 86: 114-123.
[0312] Subconjunctival Administration
[0313] Certain aspects of the disclosure are directed to subconjunctival delivery of a therapeutic agent (e.g., administration of an AAV construct to a location that is between the conjunctiva and the sclera). See, e.g., Sue Stevens, Community Eye Health. 2009 Mar; 22(69): 15.
[0314] In some aspects, the subconjunctival delivery is a subconjunctival injection.
[0315] Peribulbar Administration
[0316] Certain aspects of the disclosure are directed to peribulbar delivery of a therapeutic agent (e.g., administration of an AAV construct to a location that is in the orbit around the equator of the eye ball). See, e.g., Alhassan MB, Kyari F, Ejere HOD. Peribulbar versus retrobulbar anaesthesia for cataract surgery. Cochrane Database of Systematic Reviews 2015, Issue 7. Art. No.: CD004083.
[0317] In some aspects, the peribulbar delivery is a post-septal injection (see, e.g., FIG. 2). In some aspects, the peribulbar injection comprises advancing a needle until it penetrates the orbital septum.
[0318] In some aspects, the peribulbar injection uses a 25-gauge needle advanced to about 20 mm to about 25 mm depth, or near the equator of the globe. In some aspects the needle is advanced further than 25 mm, past the equator of the globe. In some aspects, the peribulbar injection delivers a volume of about 5 mL to about 10 mL.
[0319] During peribulbar injection, the needle is introduced into the extraconal space to avoid risk of injury to major structures in the intraconal space. Peribulbar injections are generally performed in the inferior space, with additional superior injections given if required.
[0320] Peribulbar injection was first introduced by Bloomberg et al. in 1986 as a safer and effective alternative to retrobulbar administration, the technique is frequently used for delivery of lidocaine or benzodiazepines to provide ocular akinesia and anesthesia prior to ocular surgery, especially cataract surgery (Bloomberg, L.B., J Cataract Refract Surg 12(6): 677-679 (1986), Alhassan, M.B., et al., Cochrane Database Syst Rev 2015(7):CD004083 (2015), Pucchio, A., et al., Int Ophthalmol 43(5): 1761-1769 (2023)). For deeper extraocular drug penetration, peribulbar injection has been used for treating ocular conditions such as uveitis, cystoid macular edema, and aged-related macular degeneration (Chew, E.Y., et al., Retina 31(2): 284-289 (2011), Sodhi, G., et al., Ophthalmology Management 22(August 2018): 30-38 (2018)).
[0321] Peribulbar injection of corticosteroids in TED patients has been explored in studies and improvements were observed in proptosis, inflammation, diplopia, and lid retraction without the systemic side effects accompanying oral corticosteroids such as increased body weight, hyperglycemia, and hypertension (Bartalena, L., et al., Baillieres Clin Endocrinol Metab 11(3): 521-536 (1997), Ebner, R., et al., Br J Ophthalmol 88(11): 1380-1386 (2004), Bordaberry, M., et al., Acta Ophthalmol 87(1): 58-64 (2009), Alkawas, A. A., et al., Clin Exp Ophthalmol 38(7): 692-697 (2010), Wang, Y., et al., Exp Ther Med 20(3): 2031-2038 (2020)).
[0322] Peribulbar procedure-related events are rare. This is mainly due to needle placement into the extraconal compartment rather than deeper into the intraconal space where additional optical structures are located (i.e., retrobulbar injection). Major complications of peribulbar blocks conducted in patients undergoing ophthalmic surgery have been reported at 0.006% (Kazancioglu, L., et al., Turk J Anaesthesiol Reanim 45(4): 231-233 (2017)). The risk of hemorrhage due to needle puncture of blood vessels is extremely low (0.74%across 16,224 procedures (Davis, D.B., et al., J Cataract Refract Surg 20(3): 327-337 (1994)) and no cases across 2684 procedures (Arnold, P. N., et al., J Cataract Refract Surg 18(2): 157-161 (1992)). In a case study of 16,224 peribulbar procedures, other potential risks such as globe perforation, expulsive hemorrhage, and grand mal seizure were rare occurrences (0.006%, 0.013%, and 0.006%, respectively); cardiac or respiratory depression did not occur in any patients (Davis 1994).
[0323] In some aspects, administration of an AAV construct (e.g., AAV9.smCBA.teprotumumab or AAV9.CAG.teprotumumab) of the disclosure via the peribulbar route concentrates exposure at the site of disease pathogenesis, the extraocular muscle and / or expanded adipose tissue. In some aspects, localized delivery limits IGF1R inhibition to relevant disease cells in the orbit and minimizes systemic exposure, mitigating the off-target toxicities observed with intravenous administration of Tepezza. In some aspects, local transduction of adipose tissue in the periorbital space can act as an added safeguard in that the tissue can be removed if overexpression or tolerability issues arise, as fat debulking surgery is a commonly performed procedure in TED patients.
[0324] In some aspects, the AAV construct (e.g., AAV9.smCBA.teprotumumab or AAV9.CAG.teprotumumab) will be administered as a bilateral injection (both eyes). While bilateral TED can present asymmetrically, true unilateral patients are rare, and patients initially diagnosed with clinical unilateral disease typically progress to bilateral disease (Strianese, D., et al., BMC Ophthalmol 13: 21 (2013)). Additionally, clinical evaluation using computed tomography has shown that 90% of unilateral patients have subclinical bilateral disease (Strianese 2013). Single eye intervention for bilateral TED patients can increase ocular discomfort and diplopia due to normalization of the treated eye while the fellow eye remains proptosed, similar to unilateral orbital myosis, leaving patients in need of acute surgical intervention (Kang, M.S., et al., J clin Med 9(4) (2020)). In some aspects, the AAV construct (e.g., AAV9.smCBA.teprotumumab or AAV9.CAG.teprotumumab) is administered as bilateral peribulbar injections to TED patients to balance orbital exposure.
[0325] Safety of intraocular gene therapies can be evaluated unilaterally to protect vision, as multiple barriers within the ocular space minimize contralateral and systemic exposure; however, AAV immune responses prohibit subsequent treatment of the fellow eye. Because peribulbar injections occur outside the typical barriers for intraocular drug delivery (i.e., sclera, orbital septum, and the blood-ocular barrier), serum exposure is higher for this routethan intravitreal injection, but remains lower than oral delivery (Weijtens, O., et al., Am J Ophthalmol 123(3): 358-363 (1997)). In some aspects, the AAV construct (e.g., AAV9.smCBA.teprotumumab or AAV9.CAG.teprotumumab) is administered as a unilateral peribulbar injection to a TED patient (e.g., a Ted patient with unilateral disease).
[0326] Post-Septal Administration
[0327] Certain aspects of the disclosure are directed to post-septal delivery of a therapeutic agent (e.g., administration of an AAV construct to a location that is situated or occurring between the inferior orbital septum and the inferior orbital rim).
[0328] In some aspects, the post-septal delivery is a post-septal injection (see, e.g., FIG. 2). In some aspects, the post-septal injection comprises advancing a needle until it penetrates the orbital septum.
[0329] In some aspects, a post-septal injection is a type of periocular injection that is restricted to an area anterior to the equator of the globe. The septum is a pad of tissue found both above and below the eye, and a post-septal injection is made just past the septum. In some aspects, the post-septal injection penetrates the septum between about 10 mm to about 15 mm.III. Ophthalmic Pathology
[0330] Certain aspects of the disclosure are directed to periocular administration to a subject suffering from an ophthalmic pathology.

[0500] Also provided herein are antibody expression cassettes encoding an antibody or antigen-binding fragment thereof described herein or a domain thereof that are optimized, e.g., by codon / RNA optimization, replacement with heterologous signal sequences, and elimination of mRNA instability elements. Methods to generate optimized nucleic acids encoding an antibody or antigen-binding fragment thereof described herein or a domain thereof (e.g., heavy chain, light chain, VH domain, or VL domain) for recombinant expression by introducing codon changes (e.g., a codon change that encodes the same amino acid due to the degeneracy of the genetic code) and / or eliminating inhibitory regions in the mRNA can be carried out by adapting the optimization methods described in, e.g., U.S. Patent Nos. 5,965,726; 6,174,666; 6,291,664; 6,414,132; and 6,794,498, accordingly, each of which is incorporated herein by reference in its entirety.
[0501] Antibody expression cassettes described herein can be generated from nucleic acid from a suitable source using methods well known in the art (e.g., PCR and other molecular cloning methods). For example, PCR amplification using synthetic primers hybridizable to the 3’ and 5’ ends of a known sequence can be performed using genomic DNA obtained from hybridoma cells producing the antibody of interest. In some aspects, the hybridoma cell line has the accession number DSM ACC 2587 (deposited Oct. 4, 2003). In some aspects, the hybridoma cell line has the accession number DSM ACC 2594 (deposited Sep. 05, 2003). Such PCR amplification methods can be used to obtain nucleic acids comprising the sequence encoding the light chain and / or heavy chain of an antibody or antigen-binding fragment thereof. Such PCR amplification methods can be used to obtain nucleic acids comprising the sequence encoding the variable light chain region and / or the variable heavy chain region of an antibody or antigen-binding fragment thereof. The amplified nucleic acids can be cloned into vectors for expression in host cells and for further cloning, for example, to generate chimeric and humanized antibodies or antigen-binding fragments thereof.
[0502] Antibody expression cassettes provided herein can be, e.g., in the form of RNA or in the form of DNA. DNA includes cDNA, genomic DNA, and synthetic DNA, and DNA can be double-stranded or single- stranded. If single stranded, DNA can be the coding strand or non-coding (anti-sense) strand. In some aspects, the antibody expression cassette is a cDNA or a DNA lacking one more endogenous introns. In some aspects, an antibody expression cassettes is a non-naturally occurring antibody expression cassette. In some aspects, an antibody expression cassette is recombinantly produced. In some aspects, the antibody expression cassettes are isolated. In some aspects, the antibody expression cassettes are substantially pure. In some aspects, an antibody expression cassette is purified from natural components.
[0503] In some aspects, a viral vector disclosed herein comprises an antibody expression cassette comprising coding regions for two or more polypeptides, e.g., a heavy chain and a light chain.
[0504] When it is desired the antibody expression cassette includes coding regions for two or more individual polypeptide chains, each additional coding region beyond the first is preferably linked to an element that facilitates co-expression of the proteins in host cells, such as an internal ribosomal entry sequence (IRES) element (See e.g., U.S. Patent No. 4,937,190), furin cleavage site, a 2A element, or promoter(s). In some aspects, IRES furin cleavage sites, or 2A elements can be used when a single vector comprises sequences encoding each subunit of a multi-subunit protein. In the case when the protein of interest is immunoglobulin with a desired specificity, for example, the first coding region (encoding either the heavy or light chain of immunoglobulin) is located downstream from the promoter. The second coding region (encoding the remaining chain of immunoglobulin) can be located downstream from the first coding region, and an IRES, furin cleavage site, or 2A element can be disposed between the two coding regions, e.g., immediately preceding the second coding region. In some aspects, the incorporation of an IRES, furin cleavage site, or 2A element between the sequences of a first and second gene (encoding the heavy and light chains, respectively) can allow both chains to be expressed from the same promoter at about the same level in the cell.
[0505] In some aspects, the protein of interest comprises two or more subunits, for example an immunoglobulin (Ig). In some aspects, a delivery vector of the disclosure can include a coding region for each of the subunits. For example, the viral vector can include both thecoding region for the Ig heavy chain (or the variable region of the Ig heavy chain) and the coding region for the Ig light chain (or the variable region of the Ig light chain). In some aspects, the vectors include a first coding region for the heavy chain variable region of an antibody, and a second coding region for the light chain variable region of the antibody. In some aspects, the two coding regions can be separated, for example, by a 2A selfprocessing sequence to allow multi-cistronic transcription of the two coding regions.
[0506] The viral vector can include coding regions for two or more proteins of interest. For example, the viral vector can include the coding region for a first protein of interest and the coding region for a second protein of interest. The first protein of interest and the second protein of interest can be the same or different.
[0507] The Kozak consensus sequence, Kozak consensus or Kozak sequence, is known as a sequence which occurs on eukaryotic mRNA and has the consensus (gcc)gccRccAUGG, where R is a purine (adenine or guanine) three bases upstream of the start codon (AUG), which is followed by another "G." In some aspects, the vector comprises a nucleotide sequence having at least about 85%, at least about 90%, at least about 95% sequence identity, or more to the Kozak consensus sequence. In some aspects, the vector comprises a Kozak consensus sequence. In some aspects, the vector includes a Kozak consensus sequence after the polynucleotide encoding one or more proteins of interest is inserted into the vector, e.g., at the restrict site downstream of the promoter. For example, the vector can include a nucleotide sequence of GCCGCCATG, where the ATG is the start codon of the protein of interest. In some aspects, the vector comprises a nucleotide sequence of GCGGCCGCCATG (SEQ ID NO: 84), where the ATG is the start codon of the protein of interest.
[0508] In certain aspects, a composition comprising a delivery vector, e.g., a viral vector, comprising nucleic acids encoding a therapeutic agent of interest (e.g., an antibody or an antigen binding fragment thereof, such as an anti-IGF-lR antibody or antigen binding fragment thereof) are provided for herein.V.

[0529] For eukaryotic expression, the vector construct or expression construct can comprise at a minimum a eukaryotic promoter operably linked to a DNA of interest, which is in turn operably linked to a polyadenylation sequence. The polyadenylation signal sequence can be selected from any of a variety of polyadenylation signal sequences known in the art. In some aspects, the polyadenylation signal sequence is the SV40 early polyadenylation signal sequence. In some aspects, the polyadenylation signal sequence is the bovine growth hormone polyadenylation signal sequence (bGHpA). In some aspects, the polyadenylation signal sequence is the human growth hormone polyadenylation signal sequence (hGHpA).

The construct can also include one or moreintrons, which can increase levels of expression of the DNA of interest, particularly where the DNA of interest is a cDNA (e.g., contains no introns of the naturally-occurring sequence). Any of a variety of introns known in the art can be used (e.g., the human P- globin intron, which is inserted in the vector construct or expression construct at a position 5' to the DNA of interest). In some aspects, the intron is an SV40 intron. In some aspects, the intron is from an immunoglobulin heavy chain.

[0531] When it is desired to include coding regions for two or more individual polypeptide chains, or two or more subunits of a protein of interest in one viral vector, each additional coding region beyond the first is preferably linked to an element that facilitates coexpression of the proteins in host cells, such as an internal ribosomal entry sequence (IRES) element (See e.g., U.S. Patent No. 4,937,190), or a 2A element. In some aspects, IRES, furin cleavage site, or 2A elements can be used when a single vector comprises sequences encoding each subunit of a multi-subunit protein. In the case when the protein of interest is immunoglobulin with a desired specificity, for example, the first coding region (encoding either the heavy or the light chain of immunoglobulin) is located downstream from the promoter. The second coding region (encoding the remaining chain of immunoglobulin) can be located downstream from the first coding region, and an IRES, furin cleavage site, or 2A element can be disposed between the two coding regions, e.g., immediately preceding the second coding region. In some aspects, the incorporation of an IRES, furin cleavage site, or 2A element between the sequences of a first and second gene (encoding the heavy and light chains, respectively) can allow both chains to be expressed from the same promoter at about the same level in the cell.

[0556] In some aspects, the delivery vector comprising the DNA of interest (e.g, a nucleic acid encoding a therapeutic agent of interest (e.g, an antibody or an antigen binding fragment thereof, such as an anti-IGF-lR antibody or antigen binding fragment thereof) is a viral vector. In some aspects, the viral vectors used in accordance with the disclosure are composed of a viral particle derived from a naturally-occurring virus, which has been genetically altered to render the virus replication-defective and to express a recombinant gene of interest in accordance with the disclosure. Once the virus delivers its genetic material to a cell, it does not generate additional infectious viruses but does introduce exogenous recombinant genes into the cell, preferably into the genome of the cell.
[0557] In some aspects, the viral vector is a retrovirus, an adenovirus, an adeno-associated virus (AAV), a herpes simplex virus (HSV), a cytomegalovirus (CMV), a vaccinia and a poliovirus vectors. In some aspects, retroviral vectors are less preferred since retroviruses require replicating cells and target organs can comprise slowly replicating and / or terminally differentiated cells. In some aspects, adenovirus and AAV are preferred viral vectors since this virus efficiently infects slowly replicating and / or terminally differentiated cells. Insome aspects, the delivery vector (e.g., viral vector) is selected from the group consisting of an adeno-associated viral (AAV) vector, an adenoviral vector, a lentiviral vector, or a retroviral vector.
[0558] Where a replication-deficient virus is used as the viral vector, the production of infective virus particles containing either DNA or RNA corresponding to the DNA of interest can be produced by introducing the viral construct into a recombinant cell line, which provides the missing components essential for viral replication. In some aspects, transformation of the recombinant cell line with the recombinant viral vector will not result in production of replication-competent viruses, e.g., by homologous recombination of the viral sequences of the recombinant cell line into the introduced viral vector. Methods for production of replication-deficient viral particles containing a nucleic acid of interest are well known in the art and are described in, e.g., Rosenfeld et al., Science 252:431-434 (1991) and Rosenfeld et al., Cell 68: 143-155 (1992) (adenovirus); U.S. Patent No. 5,139,941 (adeno-associated virus); U.S. PatentNo. 4,861,719 (retrovirus); and U.S. Patent No. 5,356,806 (vaccinia virus).VI. Adeno-Associated Virus (AAV)-Mediated Gene Therapy
[0559] In some aspects, the disclosure is directed to periocular delivery of a vector comprising the DNA of interest (e.g., a nucleic acid encoding a therapeutic agent of interest (e.g., an antibody or an antigen binding fragment thereof, such as an anti-IGF-lR antibody or antigen binding fragment thereof), wherein the vector is an AAV vector. AAV, a parvovirus belonging to the genus Dependovirus, has several features not found in other viruses. For example, AAV can infect a wide range of host cells, including non-dividing cells. Furthermore, AAV can infect cells from different species. AAV has not been associated with any human or animal disease, and does not appear to alter the physiological properties of the host cell upon integration. Finally, AAV is stable at a wide range of physical and chemical conditions, which lends itself to production, storage, and transportation requirements.
[0560] The AAV genome, a linear, single-stranded DNA molecule containing approximately 4700 nucleotides (the AAV-2 genome includes 4681 nucleotides), generally comprises an internal non-repeating segment flanked on each end by inverted terminal repeats (ITRs). The ITRs are approximately 145 nucleotides in length (AAV-1 has ITRs of143 nucleotides) and have multiple functions, including serving as origins of replication, and as packaging signals for the viral genome.
[0561] The internal non-repeated portion of the genome includes two large open reading frames (ORFs), known as the AAV replication (rep) and capsid (cap) regions. These ORFs encode replication and capsid gene products, respectively: replication and capsid gene products (i.e., proteins) allow for the replication, assembly, and packaging of a complete AAV virion. More specifically, a family of at least four viral proteins are expressed from the AAV rep region: Rep 78, Rep 68, Rep 52, and Rep 40, all of which are named for their apparent molecular weights. The AAV cap region encodes at least three proteins: VP1, VP2, and VP3.
[0562] AAV is a helper-dependent virus, requiring co-infection with a helper virus (e.g., adenovirus, herpesvirus, or vaccinia virus) in order to form functionally complete AAV virions. In the absence of co-infection with a helper virus, AAV establishes a latent state in which the viral genome inserts into a host cell chromosome or exists in an episomal form, but infectious virions are not produced. Subsequent infection by a helper virus "rescues" the integrated genome, allowing it to be replicated and packaged into viral capsids, thereby reconstituting the infectious virion. While AAV can infect cells from different species, the helper virus must be of the same species as the host cell. Thus, for example, human AAV will replicate in canine cells that have been co-infected with a canine adenovirus.
[0563] In some aspects, to produce recombinant AAV (rAAV) virions containing the DNA of interest, a suitable host cell line is transfected with an AAV vector containing the DNA, but lacking rep and cap. The host cell is then infected with wild type (wt) AAV and a suitable helper virus to form rAAV virions. Alternatively, wt AAV genes (known as helper function genes, comprising rep and cap) and helper virus function genes (known as accessory function genes) can be provided in one or more plasmids, thereby eliminating the need for wt AAV and helper virus in the production of rAAV virions. The helper and accessory function gene products are expressed in the host cell where they act in trans on the rAAV vector containing the heterologous gene. The heterologous gene is then replicated and packaged as though it were a wt AAV genome, forming a recombinant AAV virion. When a patient's cells are transduced with the resulting rAAV virion, the DNA enters and is expressed in the patient's cells. Because the patient's cells lack the rep and cap genes, as well as the accessory function genes, the rAAV virion cannot further replicateand package its genomes. Moreover, without a source of rep and cap genes, wt AAV virions cannot be formed in the patient's cells. See e.g., U.S. Appl. Publ. No. 2003 / 0147853.

In some aspects, the AAV vector comprises an antibody expression cassette disclosed herein. In some aspects, the AAV vector has two ITRs (i.e., a pair of ITRs). These two ITRs flank the payload region (e.g., antibody expression cassette) at the 5' and 3' ends. The ITRs function as origins of replication comprising recognition sites for replication. ITRs comprise sequence regions, which can be complementary and symmetrically arranged.

[0600] Wild-type untranslated regions (UTRs) of a gene are transcribed but not translated. Generally, the 5' UTR starts at the transcription start site and ends at the start codon and the 3' UTR starts immediately following the stop codon and continues until the termination signal for transcription.
[0601] Features typically found in abundantly expressed genes of specific target organs can be engineered into UTRs to enhance transcribed product stability and production.
[0602] Wild type 5' untranslated regions (UTRs) include features which play roles in translation initiation. Kozak sequences, which are commonly known to be involved in the process by which the ribosome initiates translation of many genes, are usually included in 5' UTRs. Kozak sequences have the consensus CCR(R)CCAUGG, where R is a purine (adenine or guanine) three bases upstream of the start codon (ATG), which is followed by another 'G. In some aspects, the 5' UTR in an AAV vector of the present disclosure includes a Kozak sequence. In some aspects, the 5' UTR in an AAV vector of the present disclosure does not include a Kozak sequence.
[0603] Wild type 3' UTRs are known to have stretches of Adenosines and Uridines embedded therein. These AU rich signatures are particularly prevalent in genes with high rates of turnover. Based on their sequence features and functional properties, the AU rich elements (AREs) can be separated into three classes (Chen et al, 1995, the contents of which are herein incorporated by reference in its entirety). Class I AREs, such as, but not limited to, c-Myc and MyoD, contain several dispersed copies of an AUUUA motif within U-rich regions. Class II AREs, such as, but not limited to, GM-CSF and TNF-a, possess two or more overlapping UUAUUUA(U / A)(U / A) nonamers. Class III ARES, such as, but not limited to, c-Jun and Myogenin, are less well defined. These U rich regions do not contain an AUUUA motif. Most proteins binding to the AREs are known to destabilize the messenger, whereas members of the ELAV family, most notably HuR, have been documented to increase the stability of mRNA. HuR binds to AREs of all the three classes. Engineering the HuR specific binding sites into the 3' UTR of nucleic acid molecules will lead to HuR binding and thus, stabilization of the message in vivo.
[0604] Introduction, removal or modification of 3' UTR AU rich elements (AREs) can be used to modulate the stability of polynucleotides. When engineering specific polynucleotides, e.g., payload regions of viral genomes, one or more copies of an ARE can be introduced to make polynucleotides less stable and thereby curtail translation and decrease production of the resultant protein. Likewise, AREs can be identified and removed or mutated to increase the intracellular stability and thus increase translation and production of the resultant protein.
[0605] In some aspects, the 3' UTR of an AAV vector of the present disclosure can include an oligo(dT) sequence for addition of a poly- A tail. In some aspects, an AAV vector of the present disclosure can include at least one miRNA seed, binding site or full sequence. microRNAs (or miRNA or miR) are 19-25 nucleotide noncoding RNAs that bind to the sites of nucleic acid targets and down-regulate gene expression either by reducing nucleic acid molecule stability or by inhibiting translation. A microRNA sequence comprises a "seed" region, i.e., a sequence in the region of positions 2-8 of the mature microRNA, which sequence has perfect Watson-Crick complementarity to the miRNA target sequence of the nucleic acid.
[0606] In some aspects, an AAV vector of the present disclosure can be engineered to include, alter or remove at least one miRNA binding site, sequence or seed region.
[0607] Any UTR from any gene known in the art can be incorporated into an AAV vector of the present disclosure. These UTRs, or portions thereof, can be placed in the same orientation as in the gene from which they were selected or they can be altered in orientation or location. In some aspects, the UTR used in an AAV vector of the present disclosure can be inverted, shortened, lengthened, made with one or more other 5' UTRs or 3' UTRs known in the art. As used herein, the term "altered" as it relates to a UTR, means that the UTR has been changed in some way in relation to a reference sequence. For example, a 3' or 5' UTR can be altered relative to a wild type or native UTR by the change in orientation or location as taught above or can be altered by the inclusion of additional nucleotides, deletion of nucleotides, swapping or transposition of nucleotides. In some aspects, an AAV vector of the present disclosure comprises at least one artificial UTRs, which is not a variant of a wild-type UTR. In some aspects, an AAV vector of the present disclosure comprises UTRs, which have been selected from a family of transcripts whose proteins share a common function, structure, feature or property.VI.A.5.
