Attorney Docket No.2014202-0027 SCFV- AND FAB-MODIFIED AAV CAPSIDS AND USES THEREOF CROSS REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims the benefit of U.S. Prov. Application No. 63 / 732,954 filed October 11, 2024, the entire contents of which are hereby incorporated by reference herein. FIELD OF THE INVENTION
[0002] Embodiments of the present disclosure relate to antibody-modified viral capsid proteins, including adeno-associated virus (AAV) capsid proteins modified with single-chain fragment variable (scFv) or antigen-binding fragment (Fab), as well as viruses and viral vectors comprising these modified capsid proteins. The disclosure further relates to methods of using such viruses and viral vectors for delivering nucleic acids encoding polypeptides, RNA molecules, or other therapeutic agents to cells for the treatment or prevention of diseases and disorders. BACKGROUND OF THE INVENTION
[0003] A promising approach to treating and preventing genetic and other diseases and disorders is delivery of therapeutic agents with a gene therapy vector such as a viral vector.
[0004] Certain challenges that remain with regard to the design of AAV vectors for use in gene and cell therapy include optimizing viral cell tropism and tissue-specific delivery. Antibody fragments, such as single-chain fragment variable (scFv) and antigen-binding fragment (Fab), which contain the antigen-binding domains of an antibody, offer advantages such as high specificity and affinity for antigens, low immunogenicity, and, in the case of scFv, the ability to penetrate tumor tissues and diffuse. The scFv fragment has been used to retarget lentivirus to specific lymphocyte subtypes for CAR-T cell therapies (Frank and Buchholz, Mol Ther Methods Clin Dev.2019 Mar 15; 12: 19–31).1However, attempts to modify AAV capsids with scFv have consistently resulted in significantly reduced viral titers, rendering such approaches impractical for AAV retargeting (Yang et al., Hum. Gene Ther.1998, 9, 1929 - 1937; Burning and Srivastava, Mol Ther Methods Clin Dev.2019 Mar 15; 12: 248–265).2,3- 1 - 12961406v1Attorney Docket No.2014202-0027
[0005] The present invention overcomes these limitations by providing novel AAV capsid proteins modified with scFv that, unexpectedly, can be packaged into AAV virions with titers comparable to unmodified AAV vectors. Additionally, the invention introduces a pioneering approach utilizing Fab fragments to modify AAV capsids, a strategy not previously reported for either AAV or lentiviral vectors. These modified capsids enhance the specificity and efficiency of viral vector delivery to target cells and tissues. By addressing the critical need for precise and effective targeting in gene therapy, the present invention represents a significant advancement in the field. SUMMARY OF THE INVENTION
[0006] The present disclosure relates generally to the fields of cancer therapy, autoimmune disease therapy, and gene therapy, and in particular, to viral vectors useful for the delivery of nucleic acid segments encoding various agents, e.g., therapeutic agents (e.g., chimeric antigen receptors, T cell receptors, antibodies, peptides, polypeptides, toxins, ribozymes, and catalytic RNA molecules), to selected cells and / or tissues of vertebrate animals.
[0007] In some aspects, the present disclosure provides antibody-modified capsid proteins, including those modified with single-chain fragment variable (scFv) or antigen-binding fragment (e.g., Fab), that are useful in cancer and gene therapy vectors (e.g., viral vectors), such as herpes simplex virus (HSV), alphavirus (AV), and adeno-associated virus (AAV) vectors. In some embodiments, such vectors that include antibody-modified capsid proteins can be used for the delivery of agents to desired cells or tissues, e.g., B-cells, T-cells, brain, liver, muscles, lung, kidney, heart, and other tissues, and for the treatment of mammalian diseases, disorders, and dysfunctions. In certain embodiments, viral vectors of the present invention are AAV6, which exhibits improved infectivity or specificity toward hematopoietic stem / progenitor cells, as well as other cells of the hematopoietic lineage, compared to many other AAV serotypes.4,5

[0039] The present disclosure provides modified capsid proteins and virions and viral vectors having one or more modified or altered capsid proteins, wherein the capsid proteins are modified with antibody fragments, such as single-chain fragment variable (scFv) or antigen- - 12 - 12961406v1Attorney Docket No.2014202-0027 binding fragment (Fab), to enhance targeting and / or infectivity. In various embodiments, the virions exhibit: 1) increased infectivity or specificity for a T cell or a B cell; 2) altered tropism; 3) increased cell or tissue specificity as compared to one or more other cells or tissues; 4) increased binding to target cells displaying corresponding ligands; and / or 5) an increased ability to infect and / or deliver a therapeutic gene product to a target cell when administered peritoneally, intravenously, intraventricularly, or intrathecally, as compared to a corresponding virion comprising its native or wild-type capsid protein instead of a modified capsid protein disclosed herein. In certain embodiments, the modified capsid proteins are adeno-associated virus (AAV) capsid proteins modified with scFv or Fab fragments specific for ligands such as CD19, CD3, or GD2, enabling targeted delivery to cells expressing these ligands, such as hematopoietic cells or tumor cells. Also provided are pharmaceutical compositions and methods for the use of any of the compositions disclosed herein for promoting the expression of a gene in cells, e.g., T and B cells, in an individual, e.g., for the treatment of a disease or disorder. These and other objects, advantages, and features of the invention will become apparent to those persons skilled in the art upon reading the details of the compositions and methods as more fully described below. DEFINITIONS
[0040] A "vector" as used herein refers to a macromolecule or association of macromolecules that comprises or associates with a polynucleotide and which can be used to mediate delivery of the polynucleotide to a cell. Illustrative vectors include, for example, plasmids, viral vectors, lipid nanoparticles, liposomes, and other gene delivery vehicles.
[0041] The term "AAV" is an abbreviation for adeno-associated virus, and may be used to refer to the virus itself or derivatives thereof. The term covers all subtypes and both naturally occurring and recombinant forms, except where required otherwise. The term "AAV" includes AAV type 1 (AAV1), AAV type 2 (AAV2), AAV type 3 (AAV3), AAV type 4 (AAV4), AAV type 5 (AAV5), AAV type 6 (AAV6), AAV type 7 (AAV7), AAV type 8 (AAV8), avian AAV, bovine AAV, canine AAV, equine AAV, primate AAV, non-primate AAV, and ovine AAV. "Primate AAV" refers to AAV that infect primates, "non-primate AAV" refers to AAV that infect non-primate mammals, "bovine AAV" refers to AAV that infect bovine mammals, etc. - 13 - 12961406v1Attorney Docket No.2014202-0027
[0042] The genomic sequences of various serotypes of AAV, as well as the sequences of the native terminal repeats (TRs), Rep proteins, and capsid subunits are known in the art. Such sequences may be found in the literature or in public databases such as GenBank. See, e.g., GenBank Accession Numbers NC_002077 (AAV1), AF063497 (AAV1), NC_001401 (AAV2), AF043303 (AAV2), NC_001729 (AAV3), NC_001829 (AAV4), U89790 (AAV4), NC_006152 (AAV5), AF028704 and AAB95450 (AAV6), AF513851 (AAV7), AF513852 (AAV8), and NC_006261 (AAV8), AY530579.1 (AAV9). The disclosures of which are incorporated by reference herein for teaching AAV nucleic acid and amino acid sequences. See also, e.g., Srivistava et al. (1983) J. Virology 45:555;6Chiorini et al. (1997) J. Virology 71 :6823;7Chiorini et al. (1999) J. Virology 73: 1309;8Bantel-Schaal et al. (1999) J. Virology 73:939;9Xiao et al. (1998) J. Virology 73:3994;10Muramatsu et al. (1996) Virology 221 :208;11Shade et al. (1986) J. Virol.58:921;12Gao et al. (2002) Proc. Nat. Acad. Sci. USA 99: 11854;13Moris et al. (2004) Virology 33:375-383;14international patent publications WO 00 / 28061, WO 99 / 61601, WO 98 / 11244; and U.S. Pat. No.6,156,303. In addition, polynucleotide sequences encoding any of the capsid proteins may be readily generated based on the amino acid sequence and the known genetic code, including codon-optimized sequences.
[0043] An "AAV virus" or "AAV viral particle" or "rAAV vector particle" refers to a viral particle composed of at least one AAV capsid protein (typically by all of the capsid proteins of a wild-type AAV) and an encapsidated polynucleotide rAAV vector. If the particle comprises a heterologous polynucleotide (i.e. a polynucleotide other than a wild-type AAV genome such as a transgene to be delivered to a mammalian cell), it is typically referred to as a "rAAV vector particle" or simply a "rAAV vector". Thus, production of a rAAV particle necessarily includes production of a rAAV vector, as such a vector is contained within a rAAV particle.
[0044] The term "replication defective" as used herein relative to an AAV viral vector of the invention means the AAV vector cannot independently replicate and package its genome. For example, when a cell of a subject is infected with rAAV virions, the heterologous gene is expressed in the infected cells, however, due to the fact that the infected cells lack AAV rep and cap genes and accessory function genes, the rAAV is not able to replicate further.
[0045] An "AAV variant" or "AAV mutant" as used herein refers to a viral particle composed of: a) a variant AAV capsid protein, where the variant AAV capsid protein comprises - 14 - 12961406v1Attorney Docket No.2014202-0027 at least one amino acid difference (e.g., amino acid substitution, amino acid insertion, amino acid deletion) relative to a corresponding parental AAV capsid protein, where the AAV capsid protein does not correspond to the amino acid sequence present of a naturally occurring AAV capsid protein; and, optionally, b) a heterologous nucleic acid comprising a nucleotide sequence encoding a heterologous gene product, wherein the variant AAV capsid protein confers increased binding to heparan or a heparan sulfate proteoglycan as compared to the binding by an AAV virion comprising the corresponding parental AAV capsid protein. In certain embodiments, an scFv-modified capsid protein confers: a) increased infectivity of a specific cell type compared to the infectivity of the cell type by an AAV virion comprising the corresponding parental AAV capsid protein; and / or b) altered cellular tropism as compared to the tropism of an AAV virion comprising the corresponding parental AAV capsid protein.
[0046] The abbreviation "rAAV" refers to recombinant adeno-associated virus, also referred to as a recombinant AAV vector (or "rAAV vector"). A "rAAV vector" as used herein refers to an AAV vector comprising a polynucleotide sequence not of AAV origin (i.e., a polynucleotide heterologous to AAV), typically a sequence of interest for the genetic transformation of a cell. In general, the heterologous polynucleotide is flanked by at least one, and generally by two AAV inverted terminal repeat sequences (ITRs). The term rAAV vector encompasses both rAAV vector particles and rAAV vector plasmids.
[0047] "Packaging" refers to a series of intracellular events that result in the assembly and encapsidation of an AAV particle.
[0048] "Mosaic packaging" refers to a method of producing recombinant adeno- associated virus (AAV) particles wherein the viral capsid is assembled from a combination of capsid proteins derived from two or more distinct AAV serotypes or variants. Specifically, mosaic packaging involves the incorporation of at least one capsid protein (e.g., VP1, VP2, or VP3) from a first AAV serotype or variant and at least one capsid protein from a second, different AAV serotype or variant into a single capsid structure. Such capsids, referred to as mosaic capsids, exhibit a heterogeneous composition of capsid proteins, which may confer altered functional properties, including but not limited to modified tropism, transduction efficiency, or immunogenicity, compared to capsids composed of proteins from a single AAV serotype or variant. Mosaic packaging encompasses the production of AAV particles using any - 15 - 12961406v1Attorney Docket No.2014202-0027 combination of capsid proteins from multiple serotypes or variants, whether naturally occurring, engineered, or synthetic, to encapsidate a viral genome.
[0049] AAV "rep" and "cap" genes refer to polynucleotide sequences encoding replication and encapsidation proteins of adeno-associated virus. AAV rep and cap are referred to herein as AAV "packaging genes."
[0050] A "helper virus" for AAV refers to a virus that allows AAV (e.g. wild-type AAV) to be replicated and packaged by a mammalian cell. A variety of such helper viruses for AAV are known in the art, including adenoviruses, herpesviruses and poxviruses such as vaccinia. The adenoviruses encompass a number of different subgroups, although Adenovirus type 5 of subgroup C is most commonly used. Numerous adenoviruses of human, non-human mammalian and avian origin are known and available from depositories such as the ATCC. Viruses of the herpes family include, for example, herpes simplex viruses (HSV) and Epstein- Barr viruses (EBV), as well as cytomegaloviruses (CMV) and pseudorabies viruses (PRV); which are also available from depositories such as ATCC.
[0051] "Helper virus function(s)" refers to function(s) encoded in a helper virus genome which allow AAV replication and packaging (in conjunction with other requirements for replication and packaging described herein). As described herein, "helper virus function" may be provided in a number of ways, including by providing helper virus or providing, for example, polynucleotide sequences encoding the requisite function(s) to a producer cell in trans. For example, a plasmid or other expression vector comprising nucleotide sequences encoding one or more adenoviral proteins is transfected into a producer cell along with an rAAV vector.
[0052] An "infectious" virus or viral particle is one that comprises a competently assembled viral capsid and is capable of delivering a polynucleotide component into a cell for which the viral species is tropic. The term does not necessarily imply any replication capacity of the virus. Assays for counting infectious viral particles are described elsewhere in this disclosure and in the art. Viral infectivity can be expressed as the ratio of infectious viral particles to total viral particles. Methods of determining the ratio of infectious viral particles to total viral particles are known in the art. See, e.g., Francois et al. (2018) Mol. Ther. Methods Clin. Dev., 10:223– 236;15and Zolotukhin et al. (1999) Gene Ther.6:973.16- 16 - 12961406v1Attorney Docket No.2014202-0027
[0053] A "replication-competent" virus (e.g. a replication-competent AAV) refers to a phenotypically wild-type virus that is infectious, and is also capable of being replicated in an infected cell (i.e. in the presence of a helper virus or helper virus functions). In the case of AAV, replication competence generally requires the presence of functional AAV packaging genes. In general, rAAV vectors as described herein are replication-incompetent in mammalian cells (especially in human cells) even in the presence of helper functions, by virtue of the lack of one or more AAV packaging genes. Typically, such rAAV vectors lack any AAV packaging gene sequences in order to minimize the possibility that replication competent AAV are generated by recombination between AAV packaging genes and an incoming rAAV vector. In many embodiments, rAAV vector preparations as described herein are those which contain few if any replication competent AAV (rcAAV, also referred to as RCA) (e.g., less than about 1 rcAAV per 102rAAV particles, less than about 1 rcAAV per 104rAAV particles, less than about 1 rcAAV per 108rAAV particles, less than about 1 rcAAV per 1012rAAV particles, or no rcAAV).
[0054] The term "polynucleotide" refers to a polymeric form of nucleotides of any length, including deoxyribonucleotides or ribonucleotides, or analogs thereof. A polynucleotide may comprise modified nucleotides, such as methylated nucleotides and nucleotide analogs, and may be interrupted by non-nucleotide components. If present, modifications to the nucleotide structure may be imparted before or after assembly of the polymer. The term polynucleotide, as used herein, refers interchangeably to double- and single-stranded molecules. Unless otherwise specified or required, any embodiment of the invention described herein that is a polynucleotide encompasses both the double-stranded form and each of two complementary single-stranded forms known or predicted to make up the double-stranded form.
[0055] A polynucleotide or polypeptide has a certain percent "sequence identity" to another polynucleotide or polypeptide, meaning that, when aligned, that percentage of bases or amino acids are the same when comparing the two sequences. Sequence similarity can be determined in a number of different manners. To determine sequence identity, sequences can be aligned using the methods and computer programs, including BLAST, available over the world wide web at ncbi.nlm.nih.gov / BLAST / . Another alignment algorithm is FASTA, available in the Genetics Computing Group (GCG) package, from Madison, Wis., USA, a wholly owned subsidiary of Oxford Molecular Group, Inc. Other techniques for alignment are described in Methods in Enzymology, vol.266: Computer Methods for Macromolecular Sequence Analysis - 17 - 12961406v1Attorney Docket No.2014202-0027 (1996), ed. Doolittle, Academic Press, Inc., a division of Harcourt Brace & Co., San Diego, Calif, USA. Of particular interest are alignment programs that permit gaps in the sequence. The Smith- Waterman is one type of algorithm that permits gaps in sequence alignments. See Meth. Mol. Biol.70: 173-187 (1997). Also, the GAP program using the Needleman and Wunsch alignment method can be utilized to align sequences. See J. Mol. Biol.48: 443-453 (1970).
[0056] Of interest is the BestFit program using the local homology algorithm of Smith and Waterman (Advances in Applied Mathematics 2: 482-489 (1981) to determine sequence identity. The gap generation penalty will generally range from 1 to 5, usually 2 to 4 and in many embodiments will be 3. The gap extension penalty will generally range from about 0.01 to 0.20 and in many instances will be 0.10. The program has default parameters determined by the sequences inputted to be compared. Preferably, the sequence identity is determined using the default parameters determined by the program. This program is available also from the Genetics Computing Group (GCG) package, from Madison, Wis., USA.
[0057] Another program of interest is the FastDB algorithm. FastDB is described in Current Methods in Sequence Comparison and Analysis, Macromolecule Sequencing and Synthesis, Selected Methods and Applications, pp.127-149, 1988, Alan R. Liss, Inc. Percent sequence identity is calculated by FastDB based upon the following parameters: Mismatch Penalty: 1.00; Gap Penalty: 1.00; Gap Size Penalty: 0.33; and Joining Penalty: 30.0.
[0058] A "gene" refers to a polynucleotide containing at least one open reading frame that is capable of encoding a particular gene product after being transcribed, and sometimes also translated. The term "gene" or "coding sequence" refers to a nucleotide sequence in vitro or in vivo that encodes a gene product. In some instances, the gene consists or consists essentially of coding sequence, that is, sequence that encodes the gene product. In other instances, the gene comprises additional, non-coding, sequences. For example, the gene may or may not include regions preceding and following the coding region, e.g.5' untranslated (5' UTR) or "leader" sequences and 3' UTR or "trailer" sequences, as well as intervening sequences (introns) between individual coding segments (exons).
[0059] A "gene product" is a molecule resulting from expression of a particular gene. Gene products include, e.g., a polypeptide, an aptamer, an interfering RNA, an mRNA, and the like. In particular embodiments, a "gene product" is a polypeptide, peptide, protein or interfering - 18 - 12961406v1Attorney Docket No.2014202-0027 RNA including short interfering RNA (siRNA), miRNA or small hairpin RNA (shRNA). In particular embodiments, a gene product is a therapeutic gene product, e.g., a therapeutic protein.
[0060] As used herein, a "therapeutic gene" refers to a gene that, when expressed, produces a therapeutic gene product that confers a beneficial effect on the cell or tissue in which it is present, or on a mammal in which the gene is expressed. Examples of beneficial effects include amelioration of a sign or symptom of a condition or disease, prevention or inhibition of a condition or disease, or conferral of a desired characteristic. Therapeutic genes include, but are not limited to, genes that correct a genetic deficiency in a cell or mammal.
[0061] As used herein, a "transgene" is a gene that is delivered to a cell by a vector.
[0062] "Recombinant," as applied to a polynucleotide, means that the polynucleotide is the product of various combinations of cloning, restriction or ligation steps, and other procedures that result in a construct that is distinct from a polynucleotide found in nature. A recombinant virus is a viral particle comprising a recombinant polynucleotide. The terms respectively include replicates of the original polynucleotide construct and progeny of the original virus construct.
[0063] A "control element" or "control sequence" is a nucleotide sequence involved in an interaction of molecules that contributes to the functional regulation of a polynucleotide, including replication, duplication, transcription, splicing, translation, or degradation of the polynucleotide. The regulation may affect the frequency, speed, or specificity of the process, and may be enhancing or inhibitory in nature. Control elements known in the art include, for example, transcriptional regulatory sequences such as promoters and enhancers. A promoter is a DNA region capable under certain conditions of binding RNA polymerase and initiating transcription of a coding region usually located downstream (in the 3' direction) from the promoter.
[0064] "Operatively linked" or "operably linked" refers to a juxtaposition of genetic elements, wherein the elements are in a relationship permitting them to operate in the expected manner. For instance, a promoter is operatively linked to a coding region if the promoter helps initiate transcription of the coding sequence. There may be intervening residues between the promoter and coding region so long as this functional relationship is maintained. - 19 - 12961406v1Attorney Docket No.2014202-0027
[0065] "Heterologous" means derived from a genotypically distinct entity from that of the rest of the entity to which it is being compared. For example, a polynucleotide introduced by genetic engineering techniques into a plasmid or vector derived from a different species is a heterologous polynucleotide. A promoter removed from its native coding sequence and operatively linked to a coding sequence with which it is not naturally found linked is a heterologous promoter. Thus, for example, an rAAV that includes a heterologous nucleic acid encoding a heterologous gene product is an rAAV that includes a nucleic acid not normally included in a naturally-occurring, wild-type AAV, and the encoded heterologous gene product is a gene product not normally encoded by a naturally-occurring, wild-type AAV.
[0066] As used herein, the terms "polypeptide," "peptide," and "protein" refer to polymers of amino acids of any length. The terms also encompass an amino acid polymer that has been modified; for example, disulfide bond formation, glycosylation, lipidation, phosphorylation, or conjugation with a labeling component.
[0067] By "comprising" it is meant that the recited elements are required in, for example, the composition, method, kit, etc., but other elements may be included to form the, for example, composition, method, kit etc. within the scope of the claim. For example, an expression cassette "comprising" a gene encoding a therapeutic polypeptide operably linked to a promoter is an expression cassette that may include other elements in addition to the gene and promoter, e.g. poly-adenylation sequence, enhancer elements, other genes, linker domains, etc.
[0068] By "consisting essentially of”, it is meant a limitation of the scope of the, for example, composition, method, kit, etc., described to the specified materials or steps that do not materially affect the basic and novel characteristic(s) of the, for example, composition, method, kit, etc. For example, an expression cassette "consisting essentially of a gene encoding a therapeutic polypeptide operably linked to a promoter and a polyadenylation sequence” may include additional sequences, e.g. linker sequences, so long as they do not materially affect the transcription or translation of the gene.
[0069] By "consisting of”, it means the exclusion from the composition, method, or kit of any element, step, or ingredient not specified in the claim. For example, an expression cassette "consisting of a gene encoding a therapeutic polypeptide operably linked to a promoter, and a polyadenylation sequence” consists only of the promoter, polynucleotide sequence encoding the - 20 - 12961406v1Attorney Docket No.2014202-0027 therapeutic polypeptide, and polyadenlyation sequence. As another example, a polypeptide "consisting of a recited sequence” contains only the recited sequence.
[0070] An "expression vector" as used herein encompasses a vector, e.g. plasmid, minicircle, viral vector, liposome, and the like as discussed above or as known in the art, comprising a polynucleotide which encodes a gene product of interest, and is used for effecting the expression of a gene product in an intended target cell. An expression vector also comprises control elements operatively linked to the encoding region to facilitate expression of the gene product in the target. The combination of control elements, e.g. promoters, enhancers, UTRs, miRNA targeting sequences, etc., and a gene or genes to which they are operably linked for expression is sometimes referred to as an "expression cassette." Many such control elements are known and available in the art or can be readily constructed from components that are available in the art.
[0071] A "promoter" as used herein encompasses a DNA sequence that directs the binding of RNA polymerase and thereby promotes RNA synthesis, i.e., a minimal sequence sufficient to direct transcription. Promoters and corresponding protein or polypeptide expression may be ubiquitous, meaning strongly active in a wide range of cells, tissues and species or cell- type specific, tissue-specific, or species specific. Promoters may be "constitutive," meaning continually active, or "inducible," meaning the promoter can be activated or deactivated by the presence or absence of biotic or abiotic factors. Also included in the nucleic acid constructs or vectors of the invention are enhancer sequences that may or may not be contiguous with the promoter sequence. Enhancer sequences influence promoter-dependent gene expression and may be located in the 5' or 3' regions of the native gene.
[0072] An "enhancer" as used herein encompasses a cis-acting element that stimulates or inhibits transcription of adjacent genes. An enhancer that inhibits transcription also is termed a "silencer". Enhancers can function (i.e., can be associated with a coding sequence) in either orientation, over distances of up to several kilobase pairs (kb) from the coding sequence and from a position downstream of a transcribed region.
[0073] A "termination signal sequence" as used herein encompasses any genetic element that causes RNA polymerase to terminate transcription, such as for example a polyadenylation signal sequence. - 21 - 12961406v1Attorney Docket No.2014202-0027
[0074] A "polyadenylation signal sequence" as used herein encompasses 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 "poly A site", i.e. a site on an RNA transcript to which adenine residues will be added by post- transcriptional polyadenylation.
[0075] The term "endogenous" as used herein with reference to a nucleotide molecule or gene product refers to a nucleic acid sequence, e.g. gene or genetic element, or gene product, e.g. RNA, protein, that is naturally occurring in or associated with a host virus or cell.
[0076] The term "native" as used herein refers to a nucleotide sequence, e.g. gene, or gene product, e.g. RNA, protein, that is present in a wildtype virus or cell. The term "variant" as used herein refers to a mutant of a reference polynucleotide or polypeptide sequence, for example a native polynucleotide or polypeptide sequence, i.e. having less than 100% sequence identity with the reference polynucleotide or polypeptide sequence. Put another way, a variant comprises at least one amino acid difference (e.g., amino acid substitution, amino acid insertion, amino acid deletion) relative to a reference polynucleotide or polypeptide sequence, e.g. a native polynucleotide or polypeptide sequence. For example, a variant may be a polynucleotide having a sequence identity of 70% or more with a full-length native polynucleotide sequence, e.g. an identity of 75% or 80% or more, such as 85%, 90%, or 95% or more, for example, 98% or 99% identity with the full-length native polynucleotide sequence. As another example, a variant may be a polypeptide having a sequence identity of 70% or more with a full-length native polypeptide sequence, e.g. an identity of 75% or 80% or more, such as 85%, 90%, or 95% or more, for example, 98% or 99% identity with the full-length native polypeptide sequence. Variants may also include variant fragments of a reference, e.g. native, sequence sharing a sequence identity of 70% or more with a fragment of the reference, e.g. native, sequence, e.g. an identity of 75% or 80% or more, such as 85%, 90%, or 95% or more, for example, 98% or 99% identity with the native sequence.
[0077] A “single-chain fragment variable” (scFv) is a fusion protein composed of the variable regions of the heavy (VH) and light (VL) chains of antibodies, connected by a short linker peptide. This structure enables the scFv to retain the antigen-binding specificity of the parent antibody, but in a smaller and more versatile format. scFvs are commonly used in - 22 - 12961406v1Attorney Docket No.2014202-0027 research, diagnostics, and therapeutic applications due to their ease of genetic manipulation and ability to penetrate tissues more effectively than full-length antibodies.
[0078] As used herein, a "Fab antibody" or "Fab fragment" refers to an antibody fragment that comprises a complete light chain and the variable and first constant domain (CH1) of a heavy chain, connected via a disulfide bond. The Fab fragment includes one antigen-binding site and lacks the Fc (crystallizable) region of the full-length antibody. It may be generated through proteolytic digestion of an immunoglobulin (e.g., papain cleavage) or produced recombinantly. The Fab fragment retains the ability to specifically bind to an antigen and may be human, humanized, murine, chimeric, or synthetic in origin.
[0079] CD molecules, or “Cluster of Differentiation” molecules, are cell surface proteins that serve as markers to differentiate and identify immune cells and other hematopoietic cells. They play key roles in cell signaling, communication, and immune responses. Each CD molecule is designated by a number (e.g., CD1, CD3, CD19, and CD28) and is associated with specific functions: For example, CD3 is part of the T-cell receptor complex, crucial for T-cell activation. CD28 is a co-stimulatory molecule found on the surface of T cells. It plays a crucial role in the activation and survival of T cells during the immune response.
[0080] As used herein, the terms "biological activity" and "biologically active" refer to the activity attributed to a particular biological element in a cell. For example, the "biological activity" of an "immunoglobulin", "antibody" or fragment or variant thereof refers to the ability to bind an antigenic determinant and thereby facilitate immunological function. As another example, the biological activity of a polypeptide or functional fragment or variant thereof refers to the ability of the polypeptide or functional fragment or variant thereof to carry out its native functions of, e.g., binding, enzymatic activity, etc. As a third example, the biological activity of a gene regulatory element, e.g. promoter, enhancer, Kozak sequence, and the like, refers to the ability of the regulatory element or functional fragment or variant thereof to regulate, i.e. promote, enhance, or activate the translation of, respectively, the expression of the gene to which it is operably linked.
[0081] The terms "administering" or "introducing", as used herein, refer to delivery of a vector for recombinant gene or protein expression to a cell, to cells and / or organs of a subject, or to a subject. Such administering or introducing may take place in vivo, in vitro or ex vivo. A - 23 - 12961406v1Attorney Docket No.2014202-0027 vector for expression of a gene product may be introduced into a cell by transfection, which typically means insertion of heterologous DNA into a cell by physical means (e.g., calcium phosphate transfection, electroporation, microinjection or lipofection); infection, which typically refers to introduction by way of an infectious agent, i.e. a virus; or transduction, which typically means stable infection of a cell with a virus or the transfer of genetic material from one microorganism to another by way of a viral agent (e.g., a bacteriophage).
[0082] "Transformation" is typically used to refer to bacteria comprising heterologous DNA or cells which express an oncogene and have therefore been converted into a continuous growth mode such as tumor cells. A vector used to "transform" a cell may be a plasmid, virus or other vehicle.
[0083] Typically, a cell is referred to as "transduced", "infected"; "transfected" or "transformed" dependent on the means used for administration, introduction or insertion of heterologous DNA (i.e., the vector) into the cell. The terms "transduced", "transfected" and "transformed" may be used interchangeably herein regardless of the method of introduction of heterologous DNA.
[0084] The term "host cell", as used herein refers to a cell which has been transduced, infected, transfected or transformed with a vector. The vector may be a plasmid, a viral particle, a phage, etc. The culture conditions, such as temperature, pH and the like, are those previously used with the host cell selected for expression, and will be apparent to those skilled in the art. It will be appreciated that the term "host cell" refers to the original transduced, infected, transfected or transformed cell and progeny thereof.
[0085] The terms "treatment", "treating" and the like are used herein to generally mean obtaining a desired pharmacologic and / or physiologic effect. The effect may be prophylactic in terms of completely or partially preventing a disease or symptom thereof, e.g. reducing the likelihood that the disease or symptom thereof occurs in the subject, and / or may be therapeutic in terms of a partial or complete cure for a disease and / or adverse effect attributable to the disease. "Treatment" as used herein covers any treatment of a disease in a mammal, and includes: (a) preventing the disease from occurring in a subject which may be predisposed to the disease but has not yet been diagnosed as having it; (b) inhibiting the disease, i.e., arresting its development; or (c) relieving the disease, i.e., causing regression of the disease. The therapeutic agent may be - 24 - 12961406v1Attorney Docket No.2014202-0027 administered before, during or after the onset of disease or injury. The treatment of ongoing disease, where the treatment stabilizes or reduces the undesirable clinical symptoms of the patient, is of particular interest. Such treatment is desirably performed prior to complete loss of function in the affected tissues. The subject therapy will desirably be administered during the symptomatic stage of the disease, and in some cases after the symptomatic stage of the disease.
[0086] The terms "individual," "host," "subject," and "patient" are used interchangeably herein, and refer to a mammal, including, but not limited to, human and non-human primates, including simians and humans; mammalian sport animals (e.g., horses); mammalian farm animals (e.g., sheep, goats, etc.); mammalian pets (dogs, cats, etc.); and rodents (e.g., mice, rats, etc.).

Additional exemplary sequences are included in the List of Sequences described herein.
[0098] In particular embodiments, the antibody-modified capsid protein, when present in an AAV virion, confers increased infectivity of a lymphocyte as compared to the infectivity of the hematopoietic cell by an AAV virion comprising the corresponding parental AAV capsid protein. In some cases, the hematopoietic cell is a T lymphocyte or a B lymphocyte (e.g., T cell or B cell). In other cases, the lymphocyte is a natural killer (NK) or natural killer T (NKT) cell. In other cases, the T lymphocyte is a CD4+ Helper T cell or Regulatory T cell. In other cases, the T lymphocyte is a CD8+ Cytotoxic T cell. In other cases, the B lymphocyte is a naïve B cell, an activated B cell, a plasma cell, or a memory B cell. In other cases, the B lymphocyte is a follicular B cell, a marginal zone B cell, B1 cell, or germinal center B cell. In particular embodiments, the antibody-modified capsid protein, when present in an AAV virion, confers altered tropism as compared to the tropism of the lymphocyte by an AAV virion comprising the corresponding parental AAV capsid protein.
[0099] In some embodiments, an antibody-modified capsid protein comprises an antibody or antibody fragment that binds to CD3, CD19, or GD2. Exemplary antibody or antibody fragments comprise or consist of an amino acid sequence having at least 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100% identity to SEQ ID NO: 048, 091, 093, 094, or 095. Exemplary antibody or antibody fragments are encoded by nucleic acid comprising or consisting of a nucleotide sequence having at least 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100% identity to SEQ ID NO: 012, 026, 041, or 048.
[0100] In certain embodiments, the antibody-modified capsid protein, e.g., VP2, includes more than one unit of scFv or Fab. For example, the antibody-modified AAV6 VP2 capsid protein includes a CD3-scFv, CD28-scFv, CD19-scFv, CD3-Fab, CD28-Fab, or CD19-Fab.
[0101] In certain embodiments, the antibody-modified capsid protein, e.g., VP2, includes an insertion of a scFv or Fab polypeptide linked to an extracellular binding domain of a CD molecule. In particular embodiments, the extracellular binding domain is selected from a group - 28 - 12961406v1Attorney Docket No.2014202-0027 of CD4, CD8, CD19, CD40, CD28, CD152, CD279, CD137, CD2, CD11a / CD18, CD31, CD21, CD14, CD95, CD47, CD55, CD59, CD58, CD80, and CD86.

[0103] In some embodiments, a subject antibody-modified AAV capsid does not include any other amino acid substitutions, insertions, or deletions, other than the scFv or Fab insertion relative to a corresponding parental AAV capsid protein. In other embodiments, a subject antibody-modified AAV capsid includes from 1 to about 25 amino acid insertions, deletions, or substitutions, compared to the parental AAV capsid protein, in addition to the scFv or Fab insertion relative to a corresponding parental AAV capsid protein.
[0104] In some embodiments, a subject antibody-modified AAV capsid polypeptide is a chimeric capsid, e.g., the capsid comprises a portion of an AAV capsid of a first AAV serotype and a portion of an AAV capsid of a second serotype; and comprises a scFv or Fab insertion relative to a corresponding parental AAV capsid protein.
[0105] In some embodiments, a subject antibody-modified capsid protein is isolated, e.g., purified. In some cases, a subject antibody-modified capsid protein is included in an AAV vector, which is also provided. As described in detail below, a subject antibody-modified capsid protein can be included in a recombinant AAV virion.
[0106] The scFv sequence may be inserted at various sites within the AAV capsid protein. In particular embodiments, the antibody-modified capsid protein is an AAV6 capsid protein, e.g., VP1 (SEQ ID NO: 096), and the scFv insertion site is in the Loop III region of the AAV6 capsid protein. The wild-type AAV1 virus is closely related to AAV6, with an identical capsid amino acid sequence, but for 5 amino acid substitutions. In certain other embodiments, the antibody-modified capsid is AAV6, AAV5, AAV8, AAV1, AAV2, or any other AAV serotype or derivative, including but not limited to those described herein, and the scFv insertion is present in a region of the AAV that corresponds to the Loop III region of AAV6. In certain embodiments, the scFv insertion is present at or near the tip of the 3-fold protrusion, at or near the basic amino acid residue 449, or at or near the heparan sulfate proteoglycan binding site of AAV6 capsid protein, or a corresponding site of another AAV serotype or derivative. In - 29 - 12961406v1Attorney Docket No.2014202-0027 particular embodiments, "near" indicates within two, within three, within four, or within five amino acid residues of the indicated amino acid or site. For example, the scFv insertion site can be within amino acids 447–460 or amino acids 448–464 of AAV6 capsid protein, e.g., between two adjacent amino acids selected from 447 and 448, 448 and 449, 449 and 450, 450 and 451, 451 and 452, 452 and 453, 453 and 454, 454 and 455, 455 and 456, 456 and 457, 457 and 458, 458 and 459, 459 and 460, 460 and 461, 461 and 462, 462 and 463, or 463 and 464 of AAV6 capsid protein, e.g., VP1 (SEQ ID NO: 096), or the corresponding amino acid residues in any other AAV capsid protein, e.g., VP1, VP2, or VP3.
[0107] In particular embodiments, the antibody-modified capsid protein is an AAV6 capsid protein, e.g., VP1 (SEQ ID NO: 096), and the scFv insertion site is in the Loop IV region of the AAV6 capsid protein. In certain other embodiments, the antibody-modified capsid is AAV6, AAV5, AAV8, AAV1, AAV2, or any other AAV serotype or derivative, including but not limited to those described herein, and the scFv insertion is present in a region of the AAV that corresponds to the Loop IV region of AAV6.
[0108] In particular embodiments, the scFv insertion is present at or near amino acid residue 587 of the AAV6 capsid protein, or at a corresponding site in another AAV serotype or derivative. As used herein, “near” refers to within two, within three, within four, or within five amino acid residues of the indicated amino acid or site. For example, the scFv insertion site can be within amino acids 585–590 of the AAV6 capsid protein, e.g., between two adjacent amino acids selected from 585 and 586, 586 and 587, 587 and 588, 588 and 589, or 589 and 590 of the AAV6 capsid protein, e.g., VP1 (SEQ ID NO: 096), or the corresponding amino acid residues in any other AAV capsid protein, e.g., VP1, VP2, or VP3.
[0109] In particular embodiments, the antibody-modified capsid protein is an AAV6 capsid protein, and the scFv or Fab insertion site is at the N-terminus of the VP2 capsid protein (SEQ ID NO: 097). In certain other embodiments, the antibody-modified capsid is AAV6, AAV5, AAV8, AAV1, AAV2, or any other AAV serotype or derivative, including but not limited to those described herein, and the scFv or Fab insertion is present at the N-terminal region of the VP2 protein of such AAV capsids.
[0110] In particular embodiments, the scFv or Fab sequence is fused in-frame at the amino terminus of the VP2 protein, such that the scFv or Fab is displayed on the exterior of the - 30 - 12961406v1Attorney Docket No.2014202-0027 AAV particle following capsid assembly. The insertion may include a flexible linker between the scFv or Fab and VP2 to facilitate proper folding and surface presentation. This approach may allow for receptor targeting, antigen binding, or cell-specific tropism modulation, while maintaining overall capsid integrity and packaging efficiency. The corresponding N-terminal site in other AAV serotypes (e.g., AAV1, AAV2, AAV5, AAV8) may also be used for such insertions, with appropriate adjustment based on sequence alignment and capsid architecture.
[0111] In particular embodiments, the antibody-modified capsid protein is an AAV6 capsid protein, and the scFv or Fab insertion site is at the C-terminus of one of the capsid proteins, such as VP1 (SEQ ID NO: 096), VP2 (SEQ ID NO: 097), or VP3 (SEQ ID NO: 098). In certain other embodiments, the antibody-modified capsid is AAV6, AAV5, AAV8, AAV1, AAV2, or any other AAV serotype or derivative, including but not limited to those described herein, and the scFv or Fab insertion is present at the C-terminal region of one or more of the capsid proteins of such AAV variants.
[0112] In particular embodiments, the scFv or Fab sequence is fused in-frame at the carboxyl terminus of VP1, VP2, or VP3, such that the scFv or Fab is displayed on the exterior of the AAV particle following capsid assembly. A flexible peptide linker may be included between the capsid protein and the scFv or Fab to promote proper folding, surface exposure, and functional presentation. This strategy allows for antigen binding, receptor targeting, or cell-type specific transduction, while maintaining capsid stability and genome packaging efficiency. The corresponding C-terminal site in other AAV serotypes (e.g., AAV1, AAV2, AAV5, AAV8) may also be used for such insertions, with appropriate adjustments based on structural homology and capsid architecture.
[0113] In some embodiments, a modified capsid protein is encoded by a nucleotide sequence having at least 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% identity to SEQ ID NO: 014, 039, 046, or 053.
[0114] AAV capsids are known to have icosahedral structures in which about 60 viral capsid proteins are associated, at a ratio (e.g., ratio of copy number or molar ratio) of VP1:VP2:VP3 of about 1:1:10 (Matsuzaka et al., Curr. Issues Mol. Biol.46:8464-8498 (2024)).

Exemplary packaging and producer cells are derived from Sf-9, 293, A549, or HeLa cells. AAV vectors are purified and formulated using standard techniques known in the art. - 34 - 12961406v1Attorney Docket No.2014202-0027 RECOMBINANT VIRIONS AND VIRAL VECTORS
[0122] In some embodiments, the recombinant virion or virus is, e.g., an AAV, further comprising a polynucleotide cassette comprising a sequence that encodes a gene product, e.g., a therapeutic gene product.
[0123] Illustrative examples of viral vectors suitable for gene therapy include but are not limited to retroviral vectors, lentiviral vectors, adenovirus vectors, herpes virus vectors, alphavirus vectors, baculovirus vectors and adeno-associated virus (AAV) vectors.
[0124] AAV is a 4.7 kb, single-stranded DNA virus widely utilized in gene therapy due to its favorable safety profile and robust gene delivery capabilities. Wild-type AAV is nonpathogenic, with no known etiologic association with human diseases, making recombinant AAV vectors highly attractive for clinical applications. These vectors demonstrate efficient gene delivery and sustained transgene expression across diverse tissues, including the retina, skeletal muscle, lung, and central nervous system. Notably, several AAV-based gene therapy drugs have received regulatory approval for human use, including Luxturna (voretigene neparvovec) for retinal dystrophy, Zolgensma (onasemnogene abeparvovec) for spinal muscular atrophy, Glybera (alipogene tiparvovec) for lipoprotein lipase deficiency, Hemgenix (etranacogene dezaparvovec) for hemophilia B, and Roctavian (valoctocogene roxaparvovec) for hemophilia A.
[0125] In certain embodiments, the sequence that encodes the gene product is operably linked to a promoter sequence. In certain embodiments, the polynucleotide cassette is flanked on the 5' and 3' ends by functional AAV inverted terminal repeat (ITR) sequences. By "functional AAV ITR sequences" is meant that the ITR sequences function as intended for the rescue, replication, and packaging of the AAV virion. Hence, AAV ITRs for use in the gene delivery vectors of the invention need not have a wild-type nucleotide sequence, and may be altered by the insertion, deletion, or substitution of nucleotides, or the AAV ITRs may be derived from any of several AAV serotypes, e.g., AAV1, AAV2, AAV3, AAV4, AAV5, AAV6, AAV7, AAV8, AAV9, AAV10. Certain AAV vectors have the wild-type REP and CAP genes deleted in whole or part, but retain functional flanking ITR sequences.
[0126] In certain embodiments, recombinant viruses or virions described herein comprise a heterologous nucleic acid comprising a nucleotide sequence encoding a gene product, e.g., a therapeutic gene product. In some embodiments, the gene product is an interfering RNA. In - 35 - 12961406v1Attorney Docket No.2014202-0027 some embodiments, the gene product is an aptamer. In some embodiments, the gene product is a polypeptide. In some embodiments, the gene product is a site-specific nuclease that provides for site-specific knock-down of gene function.
[0127] Where the gene product is an interfering RNA (RNAi), suitable RNAi include RNAi that decrease the level of an apoptotic or angiogenic factor in a cell. For example, an RNAi can be an shRNA or siRNA that reduces the level of a gene product that induces or promotes apoptosis in a cell. Genes whose gene products induce or promote apoptosis are referred to herein as "pro-apoptotic genes" and the products of those genes (mRNA; protein) are referred to as "pro-apoptotic gene products." Pro-apoptotic gene products include, e.g., Bax, Bid, Bak, and Bad gene products. See, e.g., U.S. Pat. No.7,846,730.
[0128] Interfering RNAs could also be against an angiogenic product, for example VEGF (e.g., Cand5; see, e.g., U.S. Patent Publication No.2011 / 0143400; U.S. Patent Publication No. 2008 / 0188437; and Reich et al. (2003) Mol. Vis.9:21017), VEGFR1 (e.g., Sirna-027; see, e.g., Kaiser et al. (2010) Am. J. Ophthalmol.150:33;18and Shen et al. (2002) Lab Invest 82:16719). See also, U.S. Pat. Nos.6,649,596, 6,399,586, 5,661,135, 5,639,872, and 5,639,736; and U.S. Pat. Nos.7,947,659 and 7,919,473.
[0129] Where the gene product is an aptamer, exemplary aptamers of interest include an aptamer against vascular endothelial growth factor (VEGF). See, e.g., Ng et al. (2006) Nat. Rev. Drug Discovery 5: 123;20and Lee et al. (2005) Proc. Natl. Acad. Sci. USA 102: 18902.21For example, a VEGF aptamer can comprise the nucleotide sequence 5'- cgcaaucagugaaugcuuauacauccg-3'. Also suitable for use is a PDGF-specific aptamer, e.g., E10030; see, e.g., Ni and Hui (2009) Ophthalmologica 223:401;22and Akiyama et al. (2006) J. Cell Physiol.207:407).23
[0130] Where the gene product is a polypeptide, in certain embodiments, the polypeptide is a chimeric antigen receptor (CAR) or a transgenic T cell receptor (TCR). For example, a CD19-specific CAR is designed to target the CD19 antigen, which is predominantly expressed on the surface of B cells. It is used in CAR-T cell therapies to treat various B-cell malignancies, such as Acute Lymphoblastic Leukemia (ALL), Diffuse Large B Cell Lymphoma (DLBCL), Mantle Cell Lymphoma (MCL), Follicular Lymphoma (FL), Non-Hodgkin Lymphoma (NHL), and Chronic Lymphocytic Leukemia (CLL). A GD2-specific CAR is designed to target the GD2 - 36 - 12961406v1Attorney Docket No.2014202-0027 antigen, which is highly expressed on the surface of certain solid tumors, particularly neuroblastoma, as well as some other cancers like osteosarcoma and melanoma. GD2-specific CAR T cell therapy is used to recognize and kill cancer cells expressing this antigen, making it a promising approach for treating these types of cancers. A transgenic TCR can target tumor- associated antigens (e.g., PRAME, NY-ESO-1, MAGE-A4), expressed by multiple solid tumors (e.g., melanoma, sarcoma, ovarian carcinoma, and breast cancer, among others). Nucleotide sequences for exemplary CARs are included as SEQ ID NOs: 063 and 064. In some embodiments, recombinant viruses or virions described herein comprise a heterologous nucleic acid comprising a nucleotide sequence having at least 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100% identity to SEQ ID NO: 063 or SEQ ID NO: 064.
[0131] In some cases, a gene product of interest is a toxin, e.g., Pseudomonas exotoxin, diphtheria toxin, and ricin are used to target cancer cells because they are the most potent cell- killing agents. One molecule of a toxin delivered to the cytoplasm of a cancer cell will be lethal for that cell. For example, a CD19-scFv- or CD19-Fab-modified AAV capsid is designed to target CD19-positive cancer cells specifically and destroy the cancer cells upon delivering and expressing the toxin inside the cells.
[0132] In some cases, a gene product of interest is a site-specific endonuclease that provide for site-specific knock-down of gene function, e.g., where the CRISPR-based gene editing nucleases knockout or decrease the expression of the PD-1 protein on T cells to improve their ability to target and kill cancer cells (Su et al., 2017. Scientific reports).24
[0133] In addition to knocking out a gene function, a site-specific nuclease can also be used to stimulate homologous recombination with a donor DNA that encodes a functional copy of the protein encoded by a defective allele. Thus, e.g., a subject rAAV virion can be used to deliver both a site-specific endonuclease that knocks out a defective allele, and can be used to deliver a functional copy of the defective allele, resulting in repair of the defective allele, thereby providing for production of a functional protein.
[0134] Site-specific endonucleases that are suitable for use include, e.g., zinc finger nucleases (ZFNs); and transcription activator-like effector nucleases (TALENs), where such site- specific endonucleases are non-naturally occurring and are modified to target a specific gene. Such site- specific nucleases can be engineered to cut specific locations within a genome, and - 37 - 12961406v1Attorney Docket No.2014202-0027 nonhomologous end joining can then repair the break while inserting or deleting several nucleotides. Such site-specific endonucleases (also referred to as "INDELs") then throw the protein out of frame and effectively knock out the gene. See, e.g., U.S. Patent Publication No. 2011 / 0301073.
[0135] In some embodiments, a nucleotide sequence encoding a gene product is operably linked to a constitutive promoter. In other embodiments, a nucleotide sequence encoding a gene product of interest is operably linked to an inducible promoter. In some instances, a nucleotide sequence encoding a gene product of interest is operably linked to a tissue-specific or cell type- specific regulatory element. In certain embodiments, the promoter selected from cytomegalovirus (CMV) promoter, Rous sarcoma virus (RSV) promoter, MMT promoter, EF- 1 alpha promoter, UB6 promoter, chicken beta-actin promoter, CAG promoter, RPE65 promoter and opsin promoter.
[0136] For example, in some instances, a nucleotide sequence encoding a gene product of interest is operably linked to a photoreceptor-specific regulatory element (e.g., a photoreceptor- specific promoter), e.g., a regulatory element that confers selective expression of the operably linked gene in a photoreceptor cell. Suitable photoreceptor-specific regulatory elements include, e.g., a rhodopsin promoter; a rhodopsin kinase promoter (Young et al. (2003) Ophthalmol. Vis. Sci.44:4076);25a beta phosphodiesterase gene promoter (Nicoud et al. (2007) J. Gene Med.9: 1015);26a retinitis pigmentosa gene promoter (Nicoud et al. (2007) supra); an interphotoreceptor retinoid-binding protein (IRBP) gene enhancer (Nicoud et al. (2007) supra); an IRBP gene promoter (Yokoyama et al. (1992) Exp Eye Res.55:225).27
[0137] For example, in some instances, a nucleotide sequence encoding a gene product of interest is operably linked to a liver or hepatocyte specific regulatory element (e.g., a liver- specific promoter), e.g., a regulatory element that confers selective expression of the operably linked gene in a liver cell, e.g., a hepatocyte. Suitable liver-specific regulatory elements include, e.g., the Apolipoprotein E / C-I hepatic control region, alone or combined with the human alpha- 1-antitrypsin core promoter; one or two copies of alpha 1 microglobulin / bikunin enhancer coupled to the core promoter of human thyroxine-binding globulin (TBG); or the promoter region referred to as "ET," and described as randomly assembled hepatocyte-specific transcription factor binding sites linked to the murine transthyretin promoter, as summarized in - 38 - 12961406v1Attorney Docket No.2014202-0027 Kattenhorn, L.M. et al, Human Gene Therapy, 2016 Dec 1; 27(12): 947-961.28Expression may be further stabilized by the inclusion of a woodchuck hepatitis virus post-transcriptional regulatory element (WPRE).
[0138] Recombinant AAV vectors comprising scFv- or Fab-modified capsid proteins described herein, and optionally encapsulating polynucleotide cassettes of the present disclosure, may be produced using standard methodology. For example, an AAV expression vector comprising a polynucleotide cassette may be introduced into a producer cell, followed by introduction of an AAV helper construct comprising a polynucleotide sequence encoding a scFv- or Fab-modified capsid protein disclosed herein, and where the helper construct includes AAV coding regions capable of being expressed in the producer cell and which complement AAV helper functions absent in the AAV vector. This is followed by introduction of helper virus and / or additional vectors into the producer cell, wherein the helper virus and / or additional vectors provide accessory functions capable of supporting efficient rAAV virus production. The producer cells are then cultured to produce rAAV. These steps are carried out using standard methodology. Replication-defective AAV virions comprising scFv- or Fab-modified capsid proteins described herein are made by standard techniques known in the art using AAV packaging cells and packaging technology. Examples of these methods may be found, for example, in U.S. Pat. Nos.5,436,146; 5,753,500, 6,040,183, 6,093,570, 6,548,286, expressly incorporated by reference herein in their entirety. Further compositions and methods for packaging of AAV in Sf9 cells are described in Chen (Patent No: US 8,945,918 B2), also incorporated by reference herein in its entirety.
[0139] As disclosed in the accompanying Examples, scFv- or Fab-modified capsid proteins described herein confer enhanced or altered cellular tropism to virions comprising the scFv- or Fab-modified capsid proteins. Accordingly, the scFv- or Fab-modified capsids may be used to enhance or alter the tropism of a virus or virion in order to enhance its tropism for a desired cell type.
[0140] In particular embodiments, the virions or viral vectors comprising a scFv- or Fab- modified capsid protein described herein are capable of delivering a gene product to lymphocytes when delivered via intravenous injection, e.g., wherein they result in the expression of at least 2-fold, at least 3-fold, at least 4-fold, at least 5-fold, at least 10-fold, at least 20-fold, at - 39 - 12961406v1Attorney Docket No.2014202-0027 least 50-fold, 100-fold, or at least 200-fold gene product as compared to a corresponding virion or viral vector that does not include a scFv- or Fab-modified capsid protein disclosed herein. In certain embodiments, these virions or viral vectors comprising a scFv- or Fab-modified capsid protein described herein are capable of selectively transducing lymphocytes at a higher level than they transduce one or more other cell types.
[0141] In particular embodiments, the virions or viral vectors comprising a scFv- or Fab- modified capsid protein described herein are capable of delivering a gene product to cancer cells such as neuroblastoma and melanoma when delivered via intravenous injection or infusion, e.g., wherein they result in the expression of at least 2-fold, at least 3-fold, at least 4-fold, at least 5- fold, at least 10-fold, at least 20-fold, at least 50-fold, 100-fold, or at least 200-fold gene product as compared to a corresponding virion or viral vector that does not include a scFv- or Fab- modified capsid protein disclosed herein. In certain embodiments, these virions or viral vectors comprising a scFv- or Fab-modified capsid protein described herein are capable of selectively transducing cancer cells at a higher level than they transduce one or more other normal cells. PHARMACEUTICAL COMPOSITIONS
[0142] Pharmaceutical compositions comprising a virion or viral vector comprising a scFv- or Fab-modified capsid protein described herein and one or more pharmaceutically acceptable diluent, carrier, or excipient are also disclosed. The subject virions or vectors can be combined with pharmaceutically acceptable carriers, diluents, and reagents useful in preparing a formulation that is generally safe, non-toxic, and desirable, and includes excipients that are acceptable for primate use. Such excipients can be solid, liquid, semisolid, or, in the case of an aerosol composition, gaseous. Examples of such carriers or diluents include, but are not limited to, water, saline, Ringer’s solutions, dextrose solution, and 5% human serum albumin. Supplementary active compounds can also be incorporated into the formulations. Solutions or suspensions used for the formulations can include a sterile diluent such as water for injection, saline solution, fixed oils, polyethylene glycols, glycerine, propylene glycol, or other synthetic solvents; antibacterial compounds such as benzyl alcohol or methyl parabens; antioxidants such as ascorbic acid or sodium bisulfite; chelating compounds such as ethylenediaminetetraacetic acid (EDTA); buffers such as acetates, citrates, or phosphates; detergents such as Tween 20 to prevent aggregation; and compounds for the adjustment of tonicity such as sodium chloride or - 40 - 12961406v1Attorney Docket No.2014202-0027 dextrose. The pH can be adjusted with acids or bases, such as hydrochloric acid or sodium hydroxide. In particular embodiments, the pharmaceutical compositions are sterile.
[0143] Pharmaceutical compositions may further include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersion. For intravenous administration, suitable carriers include physiological saline, bacteriostatic water, or phosphate buffered saline (PBS). In some cases, the composition is sterile and should be fluid to the extent that easy syringeability exists. In certain embodiments, it is stable under the conditions of manufacture and storage and is preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be, e.g., a solvent or dispersion medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, and liquid polyethylene glycol, and the like), and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion, and by the use of surfactants. Prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as mannitol, sorbitol, or sodium chloride in the composition. Prolonged absorption of the internal compositions can be brought about by including in the composition an agent which delays absorption, for example, aluminum monostearate and gelatin.
[0144] Sterile solutions can be prepared by incorporating the vector or virion in the required amount in an appropriate solvent with one or a combination of ingredients enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the active compound into a sterile vehicle that contains a basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, methods of preparation are vacuum drying and freeze-drying that yields a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof.
[0145] In one embodiment, the pharmaceutical compositions are prepared with carriers that will protect the virion or vector against rapid elimination from the body, such as a controlled release formulation, including implants and microencapsulated delivery systems. Biodegradable, - 41 - 12961406v1Attorney Docket No.2014202-0027 biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Methods for preparation of such formulations will be apparent to those skilled in the art. The materials can also be obtained commercially. Liposomal suspensions (including liposomes targeted to infected cells with monoclonal antibodies to viral antigens) can also be used as pharmaceutically acceptable carriers. These can be prepared according to methods known to those skilled in the art, for example, as described in U.S. Pat. No.4,522,811.
[0146] It may be advantageous to formulate oral, ocular or parenteral compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used herein refers to physically discrete units suited as unitary dosages for the subject to be treated; each unit containing a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specifications for the dosage unit forms of the invention are dictated by and directly dependent on the unique characteristics of the active compound and the particular therapeutic effect to be achieved, and the limitations inherent in the art of compounding such an active compound for the treatment of individuals.
[0147] Any concentration of viral particles suitable to effectively transduce mammalian cells can be prepared. For example, the viral particles may be formulated at a concentration of 1 x 108vector genomes per mL or more, for example, 5 x 108vector genomes per mL; 1 x 109vector genomes per mL; 5 x 109vector genomes per mL, 1 x 1010vector genomes per mL, 5 x l010vector genomes per mL; 1 x 1011vector genomes per mL; 5 x l0nvector genomes per mL; 1 x 1012vector genomes per mL; 5 x 1012vector genomes per mL; 1 x 1013vector genomes per mL; 1.5 x l013vector genomes per mL; 3 x 1013vector genomes per mL; 5 x 1013vector genomes per mL; 7.5 x l013vector genomes per mL; 9 x 1013vector genomes per mL; 1 x 1014vector genomes per mL, 5 x 1014vector genomes per mL or more, but typically not more than 1 x 1015vector genomes per mL.
[0148] The subject viral vector may be formulated into any suitable unit dosage, including, without limitation, 1 x 108vector genomes or more, for example, 1 x 109, 1 x 1010, 1 x 1011, 1 x 1012, or 1 x 1013vector genomes or more, in certain instances, 1 x 1014vector genomes, but usually no more than 1 x 1015vector genomes. In some cases, the unit dosage is at most - 42 - 12961406v1Attorney Docket No.2014202-0027 about 5 x 1015vector genomes, e.g.1 x 1014vector genomes or less, for example 1 x 1013, 1 x 1012, 1 x 1011, 1 x 1010, or 1 x 109vector genomes or less, in certain instances 1 x 108vector genomes or less, and typically no less than 1 x 108vector genomes. In some cases, the unit dosage is 1 x 1010to 1 x 1011vector genomes. In some cases, the unit dosage is 1 x 1010to 3 x 1012vector genomes. In some cases, the unit dosage is 1 x 109to 3 x 1013vector genomes. In some cases, the unit dosage is 1 x 108to 3 x 1014vector genomes.
[0149] In some cases, the unit dosage of a pharmaceutical composition may be measured using multiplicity of infection (MOI). By MOI it is meant the ratio, or multiple, of vector or viral genomes to the cells to which the nucleic acid may be delivered. In some cases, the MOI may be 1 x 106. In some cases, the MOI may be 1 x 105– 1 x 107. In some cases, the MOI may be 1 x 104– 1 x 108. In some cases, recombinant viruses of the disclosure are at least about 1 x 101, 1 x 102, 1 x 103, 1 x 104, 1 x 105, 1 x 106, 1 x 107, 1 x 108, 1 x 109, 1 x 1010, 1 x 1011, 1 x 1012, 1 x 1013, 1 x 1014MOI.
[0150] In some aspects, the amount of pharmaceutical composition comprises about 1 x 108to about 1 x 1015recombinant viruses, about 1 x 109to about 1 x 1014recombinant viruses, about 1 x 1010to about 1 x 1013recombinant viruses, or about 1 x 1011to about 3 x 1012recombinant viruses.
[0151] The pharmaceutical compositions can be included in a container, pack, or dispenser, e.g. syringe, e.g. a prefilled syringe, together with instructions for administration.
[0152] The pharmaceutical compositions of the invention encompass any pharmaceutically acceptable salts, esters, or salts of such esters, or any other compound which, upon administration to an animal comprising a human, is capable of providing (directly or indirectly) the biologically active metabolite or residue thereof.
[0153] The term "pharmaceutically acceptable salt" refers to physiologically and pharmaceutically acceptable salts of the compounds of the invention: i.e., salts that retain the desired biological activity of the parent compound and do not impart undesired toxicological effects thereto. A variety of pharmaceutically acceptable salts are known in the art and described, e.g., in in "Remington's Pharmaceutical Sciences", 17th edition, Alfonso R. Gennaro (Ed.), Mark Publishing Company, Easton, PA, USA, 1985 (and more recent editions thereof), in the "Encyclopaedia of Pharmaceutical Technology", 3rd edition, James Swarbrick (Ed.), Informa - 43 - 12961406v1Attorney Docket No.2014202-0027 Healthcare USA (Inc.), NY, USA, 2007, and in J. Pharm. Sci.66: 2 (1977). Also, for a review on suitable salts, see Handbook of Pharmaceutical Salts: Properties, Selection, and Use by Stahl and Wermuth (Wiley -VCH, 2002).
[0154] Pharmaceutically acceptable base addition salts are formed with metals or amines, such as alkali and alkaline earth metals or organic amines. Metals used as cations comprise sodium, potassium, magnesium, calcium, and the like. Amines comprise N-N'- dibenzylethylenediamine, chloroprocaine, choline, diethanolamine, dicyclohexylamine, ethylenediamine, N-methylglucamine, and procaine (see, for example, Berge et al., "Pharmaceutical Salts," J. Pharma Sci., 1977, 66, 119). The base addition salts of said acidic compounds are prepared by contacting the free acid form with a sufficient amount of the desired base to produce the salt in the conventional manner. The free acid form may be regenerated by contacting the salt form with an acid and isolating the free acid in the conventional manner. The free acid forms differ from their respective salt forms somewhat in certain physical properties such as solubility in polar solvents, but otherwise the salts are equivalent to their respective free acid for purposes of the present invention.
[0155] The subject polynucleotide cassette or gene delivery vector, e.g., recombinant virus (virions), can be incorporated into pharmaceutical compositions for administration to mammalian patients, particularly primates and more particularly humans. The subject polynucleotide cassette or gene delivery vector, e.g. virions can be formulated in nontoxic, inert, pharmaceutically acceptable aqueous carriers, preferably at a pH ranging from 3 to 8, more preferably ranging from 6 to 8. Such sterile compositions will comprise the vector or virion containing the nucleic acid encoding the therapeutic molecule dissolved in an aqueous buffer having an acceptable pH upon reconstitution.
[0156] In some embodiments, the pharmaceutical composition provided herein comprise a therapeutically effective amount of a vector or virion in admixture with a pharmaceutically acceptable carrier and / or excipient, for example saline, phosphate buffered saline, phosphate and amino acids, polymers, polyols, sugar, buffers, preservatives and other proteins.

Preferably, this formulation is stable for at least six months at 4° C.
[0157] In some embodiments, the pharmaceutical composition provided herein comprises a buffer, such as phosphate buffered saline (PBS) or sodium phosphate / sodium sulfate, tris buffer, glycine buffer, sterile water and other buffers known to the ordinarily skilled artisan such as those described by Good et al. (1966) Biochemistry 5:467. In particular embodiments, the pH of the buffer may be in the range of 6.5 to 7.75, preferably 7 to 7.5, and most preferably 7.2 to 7.4. The pharmaceutical composition may be formulated for various types of deliveries, including, e.g., parenteral administration, intravenous injection or infusion, and injection into the liver.

In related embodiments, the method comprises a method of altering the tropism of a virus by incorporating a scFv- or Fab-modified capsid protein disclosed herein into the virus. METHODS OF EXPRESSING GENE PRODUCTS AND TREATING DISEASES AND DISORDERS
[0163] Virions and viral vectors described herein, comprising a scFv- or Fab-modified capsid protein described herein, may be used for delivering a transgene to a cell, e.g., cells of an animal. For example, they may be used in research, e.g., to determine the effect that the gene has on cell viability and / or function. As another example, they may be used in medicine, e.g., to treat a disorder, for example, by delivering a therapeutic gene product to a cell or tissue. Thus, in some aspects of the invention, methods are provided for the expression of a gene in cells, the method comprising contacting cells with a composition of the present disclosure. In some embodiments, contacting cells with a composition of the present disclosure occurs in vitro.

[0164] For instances in particular embodiments in which mammalian cells are to be contacted in vitro with a subject virion or vector comprising a scFv- or Fab-modified capsid protein disclosed herein, the cells may be from any mammalian species, e.g., rodent (e.g., mice, rats, gerbils, squirrels), rabbit, feline, canine, goat, ovine, pig, equine, bovine, primate, human. Cells may be from established cell lines, e.g., HEK293 cells, HeLa cells, C2C12 cells, and CHO cells, or they may be primary cells, where "primary cells", "primary cell lines", and "primary cultures" are used interchangeably herein to refer to cells and cell cultures that have been derived from a subject and allowed to grow in vitro for a limited number of passages, i.e., splittings, of the culture. For example, primary cultures are cultures that may have been passaged 0 times, 1 time, 2 times, 4 times, 5 times, 10 times, or 15 times, but not enough times to go through the - 46 - 12961406v1Attorney Docket No.2014202-0027 crisis stage. Typically, the primary cell lines of the present disclosure are maintained for fewer than 10 passages in vitro.
[0165] If the cells are primary cells, they may be harvested from a mammal by any convenient method, e.g., whole explant, biopsy, leukapheresis, blood collection, etc. An appropriate solution may be used for dispersion or suspension of the harvested cells. Such solution will generally be a balanced salt solution, e.g., normal saline, PBS, Hank’s balanced salt solution, etc., conveniently supplemented with fetal calf serum or other naturally occurring factors, in conjunction with an acceptable buffer at low concentration, generally from 5-25 mM. Convenient buffers include HEPES, phosphate buffers, lactate buffers, etc. The cells may be used immediately, or they may be stored, frozen, for long periods of time, being thawed and capable of being reused. In such cases, the cells will usually be frozen in 10% DMSO, 50% serum, 40% buffered medium, or some other such solution as is commonly used in the art to preserve cells at such freezing temperatures, and thawed in a manner as commonly known in the art for thawing frozen cultured cells.
[0166] In certain embodiments, to promote expression of the transgene, the subject virion or gene delivery vector comprising a scFv- or Fab-modified capsid protein is contacted with the cells for about 30 minutes to 24 hours or more, e.g., 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 3.5 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 12 hours, 16 hours, 18 hours, 20 hours, 24 hours, etc. The subject virion or gene delivery vector comprising a scFv- or Fab- modified capsid protein may be provided to the subject cells one or more times, e.g., one time, twice, three times, or more than three times, and the cells allowed to incubate with the agent(s) for some amount of time following each contacting event, e.g., 16-24 hours, after which time the media is replaced with fresh media and the cells are cultured further. Contacting the cells may occur in any culture media and under any culture conditions that promote the survival of the cells. For example, cells may be suspended in any appropriate nutrient medium that is convenient, such as Iscove’s modified DMEM or RPMI 1640, supplemented with fetal calf serum, human AB serum, or heat-inactivated goat serum (about 5-10%), L-glutamine, a thiol, particularly 2-mercaptoethanol, and antibiotics, e.g., penicillin and streptomycin. The culture may contain growth factors to which the cells are responsive (e.g., cytokines). Growth factors, as defined herein, are molecules capable of promoting survival, growth, and / or differentiation of - 47 - 12961406v1Attorney Docket No.2014202-0027 cells, either in culture or in the intact tissue, through specific effects on a transmembrane receptor. Growth factors include polypeptides and non-polypeptide factors.

[0212] Sf9 cells (Expression Systems, Davis, CA) were cultured in Corning storage bottles at 28°C in ESF AF media (Expression Systems) supplemented with 100 units / mL penicillin and 100 µg / mL streptomycin (HyClone, Logan, UT). The cells were split 1:4 once the cell density reached about 8 x 106cells / mL for maintenance. HEK293T cells (ATCC, Manassas, VA) were cultured in T-75 flasks at 37°C in DMEM medium (ATCC) supplemented with 100 units / mL penicillin and 100 µg / mL streptomycin, and 10% FBS (ATCC) in a CO2incubator with 5% CO2. Once the cells reached confluency, they were split 1:10 every twice a week for maintenance. These cell culture methods were used to produce recombinant AAV virions comprising scFv- or Fab-modified capsid proteins, as described herein. For example, Sf9 cells were employed for baculovirus-based production of AAV6 virions modified with CD19-scFv or CD19-Fab, while HEK293T cells were used for triple transfection to generate scFv- or Fab- modified AAV6 virions, achieving titers of 1 x 1012vector genomes per mL or higher. Example 4: T-Cell Culture for Testing scFv- and Fab-Modified AAVs
[0213] Peripheral blood mononuclear cells (PBMC) were isolated from leukapheresis material of healthy donors using manual Ficoll® Paque Plus or a closed system instrument (Lovo) and cryopreserved in Cryostor® CS10. The cryopreserved PBMCs were thawed and washed with CTL medium, containing 47% Advanced RPMI medium, 47% Click’s medium, 5% Human AB serum, GlutaMAX, and Antibiotic / Antimycotic. Supernatants were removed, and cell pellets were resuspended at 5 x 107cells / mL in the presence of Benzonase®. Cells were incubated with Benzonase® at 37°C for 30 minutes, and then spun at 400 x g for 5 minutes at RT. The supernatants were removed, and the cell pellets were resuspended at approximately 2 x 107cells / mL in CTL medium. Cells were counted and plated in a G-Rex®100M or a T-75 flask at 1 x 107cells / mL in the presence of interleukin (IL)-7. T cells were either activated with CD3 and CD28 antibodies or left unstimulated. These T-cell cultures were used to evaluate the transduction efficiency and tropism of scFv- or Fab-modified AAV virions, such as CD3-scFv- modified AAV6 virions, demonstrating over 200-fold increased transduction efficiency in non- activated T cells compared to unmodified AAV6. - 60 - 12961406v1Attorney Docket No.2014202-0027 Example 5: Generation of Recombinant Baculovirus (rBV) and Determination of rBV Titer
[0214] Recombinant baculoviruses (rBVs) were generated using the Bac-to-Bac Baculovirus Expression System (Invitrogen, Carlsbad, CA) according to the manufacturer’s protocol. Briefly, shuttle plasmids containing the genes of interest, including those encoding scFv- or Fab-modified AAV capsid proteins (e.g., CD3-scFv or CD3-Fab fused to AAV6 VP2), were respectively transformed into DH10Bac competent cells. After 2 days of incubation on LB- agar plates containing appropriate concentrations of antibiotics, X-gal, and IPTG at 37°C, white colonies were picked, and miniprep bacmid DNAs were prepared. The miniprep bacmid DNAs were then used to transfect Sf9 cells to generate rBVs. The rBVs were collected and stored at 4°C in the dark if not used immediately. To amplify the rBV, Sf9 cells at 2 x 106cells / mL were infected with the rBVs at 0.01–0.1 MOI for 3 days, and supernatants were harvested and stored in the dark before use. These rBVs were used to produce scFv- or Fab-modified AAV virions.
[0215] The rBV titers were measured by quantitative PCR (QPCR) method. Briefly, 50 µL of rBV samples were respectively mixed with 50 µL of 0.2% SDS solution and heated at 95°C for 30 minutes. The heat-treated samples were diluted in ultrapure water and used for QPCR reaction. One MOI was empirically defined to contain an average of 20 rBV genome copies. This titration method was applied to rBVs encoding both scFv- and Fab-modified AAV capsid proteins, ensuring accurate quantification for downstream AAV production. Example 6: Production and Purification of scFv- and Fab-Modified AAV Particles
[0216] Recombinant baculoviruses (rBVs) were used to infect Sf9 insect cells for the production of recombinant adeno-associated virus (AAV) particles, including those with mosaic capsids comprising scFv- or Fab-modified capsid proteins. For mosaic packaging, rBVs were engineered to express capsid proteins from two or more distinct AAV serotypes or variants, including scFv- or Fab-modified variants, to form a heterogeneous capsid structure. In one embodiment, rBVs were designed to express AAV2 capsid proteins VP1 and VP3 and AAV6 capsid protein VP2 modified with either a CD3-scFv or CD19-Fab. Additional rBVs containing AAV Rep genes and rBVs carrying the AAV genome (e.g., flanked by inverted terminal repeats, ITRs, from a specified serotype such as AAV2) were used. The mosaic packaging approach described herein is applicable to any combination of capsid proteins (VP1, VP2, or VP3) from - 61 - 12961406v1Attorney Docket No.2014202-0027 any AAV serotypes or variants, including but not limited to AAV1, AAV2, AAV3, AAV4, AAV5, AAV6, AAV7, AAV8, AAV9, or engineered variants thereof, modified with scFv or Fab fragments, to produce mosaic capsids with tailored properties. Sf9 cells were co-infected with the appropriate rBVs at suitable multiplicities of infection and incubated for 3 days at 28°C in a shaker incubator. Cell pellets were collected by centrifugation and lysed in SF9 lysis buffer (50 mM Tris-HCl, pH 7.8, 50 mM NaCl, 2 mM MgCl2, 1% Sarkosyl, 1% Triton X-100, and 140 units / mL Benzonase nuclease (Sigma-Aldrich)) by sonication. Cell debris was removed by centrifugation, and the cleared lysates were transferred to ultraclear centrifuge tubes for an SW28 rotor (Beckman Coulter, Brea, CA). CsCl solutions with densities of 1.32 g / cc and 1.55 g / cc were under-layered, and the samples were centrifuged at 28,000 rpm at 15°C for approximately 20 hours to separate the AAV or mosaic particles from cellular contaminants. The separated AAV vector band, containing the AAV or mosaic capsids (e.g., composed of AAV2 VP1 / VP3 + AAV6 CD3-scFv-VP2 or AAV6 CD19-Fab-VP2), was collected using a syringe attached to an 18G needle. The collected AAV vectors were transferred into ultraclear centrifuge tubes for a 70.1 Ti rotor (Beckman Coulter), filled with 1.38 g / cc CsCl solution, and sealed. After centrifugation at 65,000 rpm for approximately 20 hours, the AAV vector band was collected with a syringe needle. The AAV vectors were buffer-exchanged using PD-10 desalting columns (GE Healthcare Bio-Sciences, Pittsburgh, PA). After filter sterilization, the scFv- or Fab- modified AAV vectors were diluted to appropriate concentrations for further experiments, achieving titers of >1 x 1013vector genomes per mL for CD3-Fab-modified AAV6. If not used immediately, they were stored at -80°C.
[0217] The titers of the AAV or mosaic samples were determined using a quantitative PCR (qPCR) method. Briefly, the samples were diluted in ultrapure water and treated with DNase I to eliminate potential contaminating DNA molecules. The treated samples were then heated at 95°C in EDTA buffer for 30 minutes to inactivate DNase I. Subsequently, the heat- treated samples were further diluted and used for qPCR reactions. The copy numbers of the scFv- or Fab-modified AAV samples were calculated based on a standard curve. This titration method was applied to both scFv- and Fab-modified AAVs, ensuring accurate quantification for downstream applications. - 62 - 12961406v1Attorney Docket No.2014202-0027 Example 7: SDS-Polyacrylamide Gel Electrophoresis (SDS-PAGE) of scFv- and Fab- Modified AAV Capsids
[0218] Purified AAV samples, including those with scFv- or Fab-modified capsid proteins, were subjected to SDS-PAGE to separate the capsid proteins according to their molecular weights. Unmodified AAV capsid proteins VP1, VP2, and VP3 have approximate molecular weights of 87 kDa, 73 kDa, and 62 kDa, respectively, while scFv- or Fab-modified capsid proteins (e.g., CD3-scFv-VP2 or CD19-Fab-VP2) exhibit higher molecular weights due to the addition of the antibody fragment. For example, CD3-Fab-modified VP2 was observed at approximately 123 kDa due to the larger size of the Fab fragment compared to scFv. The AAV samples were mixed with a loading buffer and heated at 95°C for 5 minutes to denature the capsid proteins. Approximately 1 x 1011vector genomes per lane of denatured samples were loaded and electrophoresed at about 100 V until the loading dye reached the bottom of the gel. After disassembly, the gels were stained and destained with the SimplyBlue SafeStain kit according to the manufacturer’s instructions (Thermo Fisher). The gel images were recorded with the iBright CL750 Image System (Thermo Fisher). This SDS-PAGE analysis confirmed the presence and integrity of scFv- or Fab-modified capsid proteins in AAV vectors. Example 8: AAV Transduction of HEK293 Cells
[0219] HEK293 cells were seeded on 24-well plates and were transduced with the scFv- modified AAV vectors and compared with non-modified AAV vectors. Briefly, the cells were trypsinized and resuspended in serum-containing media. Each well was seeded with 1.5 x 105cells in 0.5 mL medium overnight. The cells were transduced with different quantities of AAV vectors for 3 days and gene expression was detected with fluorescent microscope. Example 9: AAV Transduction of B cell lymphoma cell line (Daudi)
[0220] Daudi cells were rinsed with culture medium without serum and concentrated to 1 x 107cells / mL in culture medium without serum. One hundred microliters of the cells were mixed with different quantities of AAV vectors (1x103- 2x105vg / cell) and incubated for 2 hours. The cells were then transferred to a 24-well plate and 0.4 mL of culture medium containing 10% FBS were added per well. After 24 hours of incubation, 7.5 mL of culture medium containing 10% FBS were added per well. After 48-72 hours of incubation, the gene - 63 - 12961406v1Attorney Docket No.2014202-0027 expression was detected using the Cytek Aurora flow cytometry system (Cytek Biosciences, Fremont, CA). Example 10: AAV Transduction of Primary Lymphocytes
[0221] Antibody-activated or resting T cells were mixed with rAAVs at viral titers ranging from 2x104to 2x106vg / cell for 24 - 96 hours in vitro, following the Daudi transduction protocol above. T cell transduction was measured using flow cytometry, using either eGFP fluorescence or fluorescently-labeled antibodies specific for the CARs. Example 11: Killing of Cancer Cells by AAV transduced T-Cells
[0222] CAR-T cells generated using rAAV encoding a CAR specific for CD19 or GD2 were mixed with tumor targets expressing the relevant antigens at 1:1 effector-to-target ratio. The CD19-positive Raji tumor cells were used as targets for the CD19-specific CAR-T cells, while the GD2-positive KM-H2 tumor cells were used as targets for the GD2-specific CAR-T cells. Both tumor cell lines were modified to express eGFP-luciferase, so that their disappearance from the culture due to CAR-T cell-mediated cytotoxicity could be monitored via the loss of eGFP fluorescence using flow cytometry. Non-transduced or T cells transduced with rAAV encoding eGFP were used as negative controls. Specific killing was determined 48 hours after the initiation of the co-culture using the following formula: %Specific lysis = 100*(#tumor cells in control well - #tumor cells in CAR well) / #tumor cells in control well. Example 12: rBVs Carrying scFv-or Fab-Modified Capsid Protein Exhibited normal Baculovirus Titers
[0223] The recombinant baculoviruses (rBVs) carrying scFv- or Fab-modified AAV capsid proteins were generated, amplified, and compared with regular rBVs without modified capsid proteins for their ability to replicate and amplify. The results are shown in Table 1. rBV- V290 was the rBV carrying the wild-type AAV6 capsid gene, and rBV-V545 was the rBV carrying the GFP marker gene, whereas the other rBVs carried either scFv-modified AAV6 capsid genes (e.g., CD19-scFv-VP2) or Fab-modified AAV6 capsid genes (e.g., CD3-Fab-VP2). The rBV titers from all these rBVs were comparable, with titers of 9 x 108to 1 x 109genome copies / mL as measured by QPCR (as described in Example 5). These results demonstrate that - 64 - 12961406v1Attorney Docket No.2014202-0027 neither scFv- nor Fab-modified capsid proteins have a negative impact on rBV generation and amplification. Example 13: scFv- or Fab-Modified Capsid Proteins Maintain Comparable AAV Production Yields Regardless of Insertion Site
[0224] To evaluate the impact of insertion site on AAV production, scFv or Fab sequences were inserted at various positions within the VP1, VP2, or VP3 capsid proteins of AAV6. The insertion sites included the N-terminus, C-terminus, Loop III, and Loop IV of the respective capsid proteins. AAV vectors were produced in Sf9 insect cells using triple or double baculovirus infection (as described in Example 6), and the resulting yields were quantified. The data are summarized in Table 2. - 65 - 12961406v1Attorney Docket No.2014202-0027
[0225] Constructs with scFv- or Fab-modified AAV6 capsids were produced in 200 mL or 400 mL cultures using the triple or double baculovirus infection of Sf9 cells (as described in Example 6), and yields of purified AAV vectors were calculated per liter of cell culture.
[0226] The results demonstrate that insertion of scFv or Fab sequences at different capsid locations did not significantly affect AAV production yields. For instance, construct V705, which harbors CD3-scFv inserted between amino acids 449 and 450 of AAV6 VP2 within Loop III (SEQ ID NO.085), yielded 8.35 × 1013vg of purified AAV particles from a 200 mL culture (lot 24-374), equivalent to 4.18 × 10^14 vg / L.
[0227] In comparison, construct V683, with CD19-scFv fused to the N-terminus of AAV6 VP2, yielded 4.07 × 1013vg from a 200 mL culture (lot 24-299), or 2.03 × 10^14 vg / L of purified AAV vectors. A new construct, V794, with CD3-Fab fused to the N-terminus of AAV6 VP2, yielded 4.40 × 1013vg from a 200 mL culture (lot 25-298), or 2.20 × 1014vg / L of purified AAV vectors. Construct V689, in which CD3-scFv was inserted at the Loop IV position (between amino acids 587 and 588) of VP2, and construct V697, with the same insertion site on VP3, also produced high titers in multiple production lots (24-365 to 367, and 24-341 to 343, respectively). - 66 - 12961406v1Attorney Docket No.2014202-0027
[0228] Notably, V705 (Loop III insertion of CD3-scFv in VP2; lots 24-374 to 376) and V794 (N-terminal insertion of CD3-Fab in VP2; lot 25-298) consistently yielded titers comparable to those of constructs with Loop IV or C-terminal insertions.
[0229] Additionally, production yields of scFv- or Fab-modified AAV6 capsids were comparable to those of the wild-type AAV6 capsid. For example, V290 (lot 24-362), which contains unmodified AAV6 capsid sequences, produced AAV particles at levels similar to those of scFv- or Fab-modified constructs.
[0230] These results indicate that the location of scFv or Fab insertion within the AAV6 capsid does not significantly influence vector production efficiency. Example 14: Efficient Assembly of scFv-Modified Capsid Proteins into Virus Particles Regardless of Insertion Site
[0231] SDS-PAGE analysis demonstrated that incorporation of scFv-modified capsid proteins into AAV virus particles was not significantly affected by the position of the scFv insertion within the capsid protein.
[0232] As shown in FIG.3A, lane 2, a strong band corresponding to CD19scFv (SEQ ID NO: 093) fused to the N-terminus of AAV6 VP2 (SEQ ID NO: 084) was detected, indicating successful expression and incorporation. Lane 3 illustrates a mosaic AAV capsid composed of AAV2 VP1 and VP3, and AAV6 VP2 containing CD3scFv inserted between amino acids 449 and 450 (SEQ ID NO: 085). The molecular weight of the VP2-scFv fusion protein exceeded that of VP1, as expected.
[0233] In FIG.3B, lane 2 shows GD2scFv fused to the N-terminus of AAV5 VP2 (SEQ ID NO: 086) and successfully packaged into AAV5 virus particles. Similarly, lane 3 displays CD3scFv inserted at the N-terminus of AAV6 VP2 (SEQ ID NO: 087), which was efficiently packaged into AAV6 particles.
[0234] FIG.3C (lanes 2–4) shows CD3scFv inserted between amino acids 587 and 588 of AAV6 VP2 (SEQ ID NO: 088), which was effectively assembled into AAV6 virus particles. Likewise, FIG.3D (lanes 2–4) illustrates that insertion of CD3scFv between amino acids 449 and 450 of AAV6 VP2 (SEQ ID NO: 085) resulted in successful packaging into virus particles. - 67 - 12961406v1Attorney Docket No.2014202-0027
[0235] In FIG.3E, lane 2 demonstrates that CD3scFv inserted simultaneously between amino acids 451 and 452 of both AAV8 VP1 and VP2 (SEQ ID NO: 089) was successfully assembled into AAV8 virus particles. Interestingly, a partial CD3scFv-VP3 fusion protein was also detected. Despite mutation of the canonical double ATG start codons of VP3 to ATT, an alternative GTG codon located 54 bp downstream was utilized as a cryptic start site, resulting in unexpected expression and incorporation of the CD3scFv-VP3 fusion. The majority of VP3 protein in this configuration was supplied in trans from a separate plasmid construct (V734).
[0236] FIG.3F (lanes 2–4) shows that CD3scFv inserted between amino acids 587 and 588 of AAV6 VP3 (SEQ ID NO: 090) was successfully incorporated into AAV6 virus particles. The resulting CD3scFv-VP3 fusion protein exhibited a molecular weight similar to that of VP1, and the two bands overlapped, forming a strong composite band at the VP1 position. The majority of AAV6 VP3 in these particles was supplied by a separate construct (V290).
[0237] FIG.3G, lane 2, demonstrates successful incorporation of a CD3-Fab fragment fused to the N-terminus of the AAV6 VP2 capsid protein (SEQ ID NO: 092) into assembled AAV6 virions. The CD3-Fab-VP2 fusion protein exhibited the expected molecular weight of approximately 125 kDa, as confirmed by SDS-PAGE analysis. Example 15: Superior Lymphocyte Transduction Efficiency of Wild-Type AAV6 Capsid Compared to AAV-DJ and AAV8 Justifies Its Selection for scFv- and Fab-Modifications
[0238] To evaluate the transduction efficiency of recombinant adeno-associated virus (rAAV) vectors for lymphocyte gene delivery, activated T cells were transduced with rAAVs encoding enhanced green fluorescent protein (eGFP) using capsids derived from AAV6, AAV- DJ, or AAV8. As shown in FIG.4, AAV6 exhibited significantly higher transduction efficiency, achieving approximately 40% transduction at a multiplicity of infection (MOI) of 1 × 10^6 vector genomes (vg) per cell, compared to only ~2% for both AAV-DJ and AAV8 under identical conditions. This superior performance of the wild-type AAV6 capsid in lymphocyte transduction justified its selection as the primary vector for further modifications, including the development of scFv- and Fab-modified AAV6 capsids (e.g., CD3-scFv-VP2 or CD3-Fab-VP2), to enhance targeted gene delivery to lymphocytes. - 68 - 12961406v1Attorney Docket No.2014202-0027 Example 16: scFv-Modified AAV6 Capsids Enhance Transduction Efficiency in Non- Activated T Cells
[0239] To compare transduction efficiencies of recombinant adeno-associated virus (rAAV) vectors with wild-type (WT) AAV6 capsids, or CD3-scFv-modified AAV6 capsids, non-activated T cells from four healthy donors were transduced with rAAVs encoding enhanced green fluorescent protein (eGFP). The experimental design is depicted in FIG.5. Transduction results are shown in FIG.6. The top row of FIG.6A displays non-transduced peripheral blood mononuclear cell (PBMC) data, while the middle and bottom rows show the fraction of eGFP- positive T cells per donor for WT AAV6 and CD3-scFv-modified AAV6 capsids, respectively. FIG.6B demonstrates that the CD3-scFv-modified VP2 capsid significantly enhanced transduction efficiency compared to WT AAV6. FIG.6C indicates that the fold increase in transduction efficiency, after subtracting the non-transduced baseline, reached up to 280-fold for individual donors.
[0240] To further evaluate transduction efficiencies, non-activated T cells from four healthy donors were transduced with rAAVs encoding a CD19-specific chimeric antigen receptor (CAR, FMC63) using WT AAV6 capsids, or CD3-scFv-modified AAV6 capsids. The experimental design is depicted in FIG.5. Transduction results are shown in FIG.7. The top row of FIG.7A displays non-transduced PBMC data, while the middle and bottom rows show the fraction of CAR-positive T cells per donor for WT AAV6 and CD3-scFv-modified AAV6 capsids, respectively. FIG.7B demonstrates that the CD3-scFv-modified VP2 capsid significantly enhanced transduction efficiency compared to WT AAV6. FIG.7C indicates that the fold increase in transduction efficiency reached up to 200-fold for individual donors. This antibody-mediated enhancement of transduction efficiency underscores the novelty of antibody- modified AAV capsids for targeted gene delivery to non-activated T cells. Example 17: CD19-scFv-Modified AAV6 Capsids Enhance Transduction Efficiency in Daudi Cells
[0241] To compare transduction efficiencies of recombinant adeno-associated virus (rAAV) vectors with wild-type (WT) AAV6 capsids, and CD19-scFv-modified AAV6 capsids, Daudi cells (a CD19-positive B-cell line) were transduced with rAAVs encoding enhanced green fluorescent protein (eGFP) at multiplicities of infection (MOI) ranging from 1 × 103to 2 × 105- 69 - 12961406v1Attorney Docket No.2014202-0027 vector genomes (vg) per cell. As shown in FIGs.8A and 8B, CD19-scFv-modified VP2 capsids enhanced transduction efficiency at low MOI compared to WT AAV6 capsids (94.0% vs.65.4% at 1 × 103vg / cell), while at higher MOIs, efficiencies converged due to transduction saturation (98.3% vs.94.9% at 1 × 104vg / cell; 99.2% vs.98.3% at 1 × 105vg / cell). Example 18: Comparison of CD3-scFv-Modified VP2 vs. VP3 Capsid Proteins in Transduction Efficiency of Non-Activated T Cells
[0242] To compare transduction efficiencies of recombinant adeno-associated virus (rAAV) vectors with CD3-scFv-modified capsid proteins inserted into either VP2 or VP3 of AAV6, non-activated T cells from two healthy donors were transduced with rAAVs encoding either a CD19-specific chimeric antigen receptor (CAR, FMC63) or a GD2-specific CAR (14G2A). The rAAVs included constructs with CD3-scFv fused to VP2 or VP3. As shown in FIG.9, CD3-scFv-modified VP3 capsids exhibited higher transduction efficiencies than CD3- scFv-modified VP2 capsids: 13.2% vs.9.05% and 23.9% vs.19.3% for the CD19-specific CAR, and 20.3% vs.7.52% and 31.3% vs.12.2% for the GD2-specific CAR. Due to donor-to-donor variability, these differences did not reach statistical significance. Example 19: CD3-scFv-Modified VP2 Capsid Proteins with Loop IV or Loop III Insertions Exhibit Comparable Transduction Efficiencies in Non-Activated T Cells
[0243] To compare transduction efficiencies of recombinant adeno-associated virus (rAAV) vectors with CD3-scFv-modified VP2 capsid proteins of AAV6, with insertions in Loop IV or Loop III, non-activated T cells from three healthy donors were transduced with rAAVs encoding enhanced green fluorescent protein (eGFP). As shown in FIG.10, CD3-scFv-modified VP2 capsids with Loop IV versus Loop III insertions exhibited comparable transduction efficiencies: 39.2% vs.46.7% for Donor 735, 13.6% vs.12.9% for Donor 088, and 42.6% vs. 45.1% for Donor 992. Due to donor-to-donor variability, these differences were not statistically significant.

As shown in FIG.11, CD3-scFv-modified VP2 capsids with Loop IV versus Loop III insertions exhibited comparable transduction efficiencies: 47.2% vs.49.9% (Donor 735, FMC63 CAR), 9.92% vs.15.2% (Donor 088, FMC63 CAR), 36.9% vs.43.8% (Donor 992, FMC63 CAR), 33.3% vs.44.9% (Donor 735, 14G2A CAR), 9.50% vs.9.62% (Donor 088, 14G2A CAR), and 47.4% vs.52.6% (Donor 992, 14G2A CAR). Due to donor-to-donor variability, these differences were not statistically significant. Example 21: CAR-T Cells Generated by rAAV6 Transduction Using CD3-scFv-Modified VP2 Capsids with Loop IV or Loop III Insertions Exhibit Comparable Tumor-Killing Efficiency
[0245] To compare the anti-tumor activity of CAR-T cells generated by transduction with recombinant adeno-associated virus (rAAV) vectors containing CD3-scFv-modified VP2 capsid proteins of AAV6, with insertions in Loop IV or Loop III, non-activated T cells from three healthy donors were transduced with rAAVs encoding a CD19-specific chimeric antigen receptor (CAR, FMC63) or a GD2-specific CAR (14G2A). Seventy-two hours post-transduction, CAR-T cells were co-cultured with tumor cells expressing the relevant antigens at a 1:1 effector- to-target ratio for 48 hours, and tumor killing was assessed by flow cytometry, measuring the reduction in eGFP-positive tumor cells. The experimental design is shown in FIG.12A, and tumor-killing results are summarized in FIG.12B. CD3-scFv-modified VP2 capsids with Loop IV versus Loop III insertions yielded comparable specific lysis: 68.0% vs.34.0% (Donor 735, FMC63 CAR), 24.0% vs.38.0% (Donor 088, FMC63 CAR), 62.0% vs.64.0% (Donor 992, FMC63 CAR), 48.0% vs.45.0% (Donor 735, 14G2A CAR), 14.0% vs.11.0% (Donor 088, 14G2A CAR), and 60.0% vs.55.0% (Donor 992, 14G2A CAR). Due to donor-to-donor variability, these differences were not statistically significant. These data demonstrate successful use of CD3-scFv-modified capsids with either Loop IV or Loop III insertions to generate CAR-T cells with comparable tumor-killing efficiency. - 71 - 12961406v1Attorney Docket No.2014202-0027 Example 22: CD19-Specific CAR-T Cells Generated In Vivo Using Human PBMCs and CD3-scFv-Modified AAV6-FMC63CAR Administered Intraperitoneally Control Raji Tumor Growth and Improve Mouse Survival
[0246] To evaluate the in vivo efficacy of CD19-specific CAR-T cells against B-cell lymphoma, luciferase-modified Raji cells were implanted intraperitoneally (IP) in NSG mice on Day -3. On Day 0, one group received human peripheral blood mononuclear cells (PBMCs) with CD3-scFv-modified AAV6 encoding a CD19-specific CAR (FMC63; CD3scFv-AAV- FMC63CAR) IP, another received human PBMCs with CD3-scFv-modified AAV6 encoding eGFP (CD3scFv-AAV-EGFP) IP, and a third was untreated. Tumor growth was monitored twice weekly via In Vivo Imaging System (IVIS) for 31 days. The experimental design is shown in FIG.13A. IVIS images (FIG.13B) showed progressive tumor growth in untreated mice and those receiving CD3scFv-AAV-EGFP, with no untreated mice surviving past Day 28 and CD3scFv-AAV-EGFP-treated mice beginning to die by Day 18 (left-most and right-most columns, respectively). In contrast, mice treated with CD3-scFv-modified AAV6-FMC63CAR effectively controlled tumor growth through Day 31 (middle columns). FIG.13C, Panel A, quantifies average radiance (tumor burden), showing comparable tumor growth in untreated and CD3scFv-AAV-EGFP-treated groups, while CD3-scFv-modified AAV6-FMC63CAR group suppressed Raji tumor growth until Day 31. FIG.13C, Panel B, shows survival data: untreated mice died by Day 28, CD3scFv-AAV-EGFP-treated mice began dying after Day 17, while all mice treated with CD3-scFv-modified AAV6-FMC63CAR survived until Day 31. Example 23: In Vivo Generated CAR-T Cells and EGFP-Positive T Cells Can Be Found in Mouse Blood on Day 31.
[0247] To assess the persistence of the in vivo generated CAR-T and EGFP+ T cells (described in Example 22), all surviving mice were terminally bled on day 31 via cardiac puncture. The blood was analyzed for the presence of CD19-specific CAR-T cells and EGFP- positive T cells using flow cytometry. The data, shown in FIG.14, revealed that 70%-100% of the viable human hematopoietic cells, as determined using a viability dye and anti-human CD45 and CD3 antibodies, were CD3-positive T cells (FIG.14, panel A). Analysis of the CAR and EGFP expression showed that 0.16%-30.3% of the human T cells expressed the CAR and 0.23%-1.33% expressed EGFP (FIG.14, panel B). These results suggest that in vivo generated - 72 - 12961406v1Attorney Docket No.2014202-0027 CAR-T cells had undergone preferential CD19-specific expansion in response to tumor recognition, unlike the EGFP-positive T cells generated by CD3scFv-AAV-EGFP. Example 24: In Vivo Generated CD19-Specific CAR-T Cells Using Human PBMCs and CD3scFv-AAV-FMC63CAR Control Raji Lymphoma Growth upon Intravenous (IV) Administration and Improve Mouse Survival.
[0248] Having established that CD19-specific CAR-T cells can be generated in vivo following IP administration of human PBMCs and CD3scFv-AAV-FMC63CAR, and they are effective at controlling Raji tumors that are also growing IP, we evaluated whether similar results could be obtained using systemic IV administration of Raji cells, PBMCs and CD3scFv-AAV- FMC63CAR. The treatment schema is shown in FIG.15A. The IVIS images (FIG.15B) demonstrated that without treatment, Raji tumor cells grew over time and the mice did not survive past day 16 (four left-most image columns), while mice that received Raji, PBMCs and CD3scFv-AAV-FMC63CAR successfully controlled tumor growth (four right-most image columns) through day 24. Measurements of average radiance, which correlates with tumor burden (shown in FIG.15C, panel A), demonstrated that the tumors in the untreated animals were statistically significantly larger than the tumors in the mice treated with human PBMCs and CD3scFv-AAV-FMC63CAR starting on Day 3 post treatment initiation. Survival analysis (shown in panel B of FIG.15C) revealed that the untreated animals did not live past day 16, while all animals treated with human PBMCs and CD3scFv-AAV-FMC63CAR remained alive until day 24. Example 25: In Vivo Generated CAR-T Cells Using IV Administration of Human PBMCs and CD3scFv-AAV-FMC63CAR Can Be Found in Mouse Blood
[0249] To assess the persistence of the in vivo generated CAR-T cells (described in Example 24), the blood samples were analyzed for the presence of CD19-specific CAR-T cells using flow cytometry. The data revealed that more than 99% of the viable human hematopoietic cells, as determined using a viability dye and an anti-human CD45 antibody, were CD3-positive T cells (FIG.16 panel A). Analysis of the CAR expression showed that 0.3%-69.9% of the human T cells expressed the CAR (FIG.16 panel B). - 73 - 12961406v1Attorney Docket No.2014202-0027 Example 26: FMC63CAR DNA was detected in multiple mouse tissues following intravenous administration of human PBMCs and CD3scFv-AAV6-FMC63CAR in Raji- tumor-bearing animals, with biodistribution consistent with published data for wild-type AAV
[0250] To evaluate the biodistribution of FMC63CAR, liver, kidney, heart, spleen, brain, lung, ovaries, and bone marrow were collected from six mice administered human PBMCs and CD3scFv-AAV6-FMC63CAR, and three control mice, following euthanasia. Organ DNA was extracted using the DNeasy Blood and Tissue Kit, and the FMC63CAR copy number per mg of tissue was quantified by qPCR using CAR-specific primers and probe. The liver exhibited the highest CAR copy numbers, followed by the kidney, heart, and spleen, while the brain, lung, ovaries, and bone marrow showed copy numbers comparable to controls (FIG.17).
