[Figure 6] This section illustrates an exemplary workflow for producing the rAAV vector plasmid used to produce the rAAV vectors described herein. [Figure 7]The following are SDS-PAGE (Sodium Dodecyl Sulfate-Polyacrylamide Gel) results, in which 1 e11 vg of each AAV preparation, subjected to electrophoresis for protein separation on a 10% polyacrylamide gel, was loaded into a well and its purity was evaluated by Coomassie blue staining. [Figure 8A] Data from in vitro evaluations of payload production efficiency are shown. Figures 8A-8B show the relative production efficiency of various expressed AAV preparations as a ratio of each vg titer (vg / mL) divided by the vg titer of the reference stock (AAV produced using plasmid #1 (Figure 8A) or plasmid #12 (Figure 8B)). The plasmid used to produce the corresponding AAV is identified on the X axis. [Figure 8B] Data from in vitro evaluations of payload production efficiency are shown. Figures 8A-8B show the relative production efficiency of various expressed AAV preparations as a ratio of each vg titer (vg / mL) divided by the vg titer of the reference stock (AAV produced using plasmid #1 (Figure 8A) or plasmid #12 (Figure 8B)). The plasmid used to produce the corresponding AAV is identified on the X axis. [Figure 8C] Data from in vitro evaluations of payload production efficiency are shown. Figure 8C shows the vg titers obtained from each of five 1-liter (L) shaking flasks of suspended cells using plasmid #1. [Figure 9A] Data from in vitro evaluation of payload expression are shown. Figure 9A shows the measured payload expression for AAV preparations #6, #5, #8, and #9, each produced by different vendors and processes. All preparations were produced using plasmid #1, which carried a human IFNβ (hIFNβ) payload and was packaged within the same AAV capsid serotype. [Figure 9B]The data from in vitro evaluation of payload expression are shown. Figure 9B shows the measured payload expression for AAV preparations #1, #9, #10, and #11 (produced from plasmids #7, #1, #12, and #14, respectively) of various AAV genomes, produced by a single vendor using the same process and packaged within the same AAV capsid serotype. [Figure 9C] Data from in vitro evaluation of payload expression are shown. Figure 9C shows the measured payload expression for AAV preparations #6, #9, #10, #2, #13, and #16 (produced from plasmids #1, #1, #12, #7, #24, and #25, respectively) that express hIFNβ (with the exception of AAV preparation #16, which contained the reporter payload (mCardinal) and was used as a negative control). All other preparations, except for AAV preparation #6, were prepared using the same process from the same vendor. [Figure 9D] Data from in vitro evaluation of payload expression are shown. Figure 9D shows payload expression for AAV preparations #3, #6, #14, and #15 (produced from plasmids #7, #1, #24, and #24, respectively). Both AAV preparations #14 and #15 utilized plasmid #24 but were produced by two different vendors. [Figure 9E] Data from in vitro evaluation of payload expression are shown. Figure 9E shows the measured payload expression for AAV preparations #6 and #17 (produced using plasmids #1 and #26 expressing human IFNβ and mouse IFNβ, respectively). In all plots, data represent the mean ± SD of technically redundant measurements. Abbreviations: MOI, degree of multiple infection; prep, preparation. [Figure 10]This shows in vitro measurement results of cytokine payload activity for six exemplary AAVs and media (NC) expressing hIFNβ (AAV preparations #6, #9, #10, #2, and #13), as well as one AAV expressing a reporter payload (mCardinal) (AAV preparation #12) used as a negative control. Values ​​represent the mean ± SD for eight technical overlaps. [Figure 11] This report presents an in vitro evaluation of the reduction in cancer cell viability upon exposure to the AAV expression system expressing human IFNβ (AAV-hIFNβ) described herein. As shown, relative cell viability is expressed as a percentage at day 6 after exposure to low, medium, or high doses of AAV-hIFNβ or AAV-GFP. Staurosporine (STS) was used as the positive killing target, and data are expressed as mean ± SD using technical replication of n=4. [Figure 12] This shows the levels of hIFNβ secreted from in vitro transduced GBM cells, as measured by ELISA. The values ​​represent the mean ± SD of four technical replications. [Figure 13] This specification provides exemplary processes and assays for the production of the AAV constructs described herein. [Modes for carrying out the invention]

[0027] Cancer remains the second leading cause of death in the United States, after heart disease. In 2023, the U.S. is projected to see a total of 1.9 million new cancer cases (approximately 5,370 per day) and 609,820 cancer-related deaths (approximately 1,670 per day). The treatment repertoire for many cancers (e.g., glioblastoma, metastatic brain tumors, and uveal melanoma) remains largely limited to invasive and / or cytotoxic approaches, including resection, radiation, chemotherapy, and combinations thereof. Even common immuno-based oncological drugs, such as cytokine therapy, exhibit negative characteristics, including toxicity from systemic administration, short half-lives, and lack of specificity. Furthermore, there remain challenges in methods for effectively delivering therapeutic agents to cancer tissue.

[0028] There is a need for improved treatments for cancer (e.g., glioblastoma, metastatic brain tumors, uveal melanoma), including cytokine therapies with improved characteristics such as low toxicity, long-term and stable sustained expression, improved delivery (e.g., local delivery to tumors), and low doses. Compositions and methods relating to rAAV delivery of target payloads, such as cytokines including interferon, are provided herein.

[0029] definition Unless otherwise specified, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to the extent of the subject matter. In general, the nomenclature and techniques used in relation to immunology, oncology, cell and tissue culture, molecular biology, and protein expression and oligonucleotide or polynucleotide chemistry, and hybridization described herein are well known and commonly used in the art. Units of measurement, unless otherwise defined, follow the International System of Units (SI), NIST SP330, 2019 edition.

[0030] Where used herein, all numbers or numerical ranges include the entire integer within or encompassing such a range, and any value or integer within that range, unless the context clearly indicates otherwise. Thus, for example, a reference to the range 90–100% includes 91%, 92%, 93%, 94%, 95%, 95%, 97%, etc., as well as 91.1%, 91.2%, 91.3%, 91.4%, 91.5%, etc., 92.1%, 92.2%, 92.3%, 92.4%, 92.5%, etc. In another example, references to the range of 1 to 5,000 times include 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 11x, 12x, 13x, 14x, 15x, 16x, 17x, 18x, 19x, 20x, etc., as well as 1.1x, 1.2x, 1.3x, 1.4x, 1.5x, etc., and 2.1x, 2.2x, 2.3x, 2.4x, 2.5x, etc.

[0031] The terms used herein are intended solely to describe specific embodiments and are not intended to limit any embodiments. Where used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context otherwise expressly indicates otherwise. Furthermore, the terms “comprises” and / or “comprising,” where used herein, specify the presence of the described features, integers, processes, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integers, processes, operations, elements, components, and / or groups thereof. Where used herein, the terms “and / or” include any and all combinations of one or more of the enumerated items relating to the subject.

[0032] As used herein, “adeno-associated virus vector” or “AAV vector” refers to, but is not limited to, AAV1, AAV2, AAV3, AAV4, AAV5, AAV6, AAV7, AAV8, AAV9, AAV10, AAV11, AAV12, AAV13, AAV14, AAV15, AAV16, AAV-rh8, AAV-rh10, AAV-rh20, AAV-rh39, AAV-rh74, AAV-rhM4-1, AAV-hu37, AAV-Anc80, AAV-Anc80L65, AAV-7m8, AAV-PHP-B, AAV-PHP-EB, AAV-2.5, AA This refers to vectors derived from adeno-associated virus serotypes including V-2tYF, AAV-3B, AAV-LK03, AAV-HSC1, AAV-HSC2, AAV-HSC3, AAV-HSC4, AAV-HSC5, AAV-HSC6, AAV-HSC7, AAV-HSC8, AAV-HSC9, AAV-HSC10, AAV-HSC11, AAV-HSC12, AAV-HSC13, AAV-HSC14, AAV-HSC15, AAV-TT, AAV-DJ / 8, AAV-Myo, AAV-NP40, AAV-NP59, AAV-NP22, AAV-NP66, or AAV-HSC16. An AAV vector may have one or more AAV wild-type genes, e.g., Rep genes and / or Cap genes, that are entirely or partially deleted, but retain functional adjacent inverted terminal repeat (ITR) sequences. Functional ITR sequences facilitate rescue, replication, and packaging of AAV virions. Therefore, an AAV vector is defined herein to contain at least those sequences on the same side for at least replication and viral packaging (e.g., functional ITRs). The ITRs do not have to be wild-type polynucleotide sequences and, in some embodiments, can be modified, for example, by nucleotide insertions, deletions, or substitutions, as long as the sequences provide functional rescue, replication, and packaging.

[0033] The term “adeno-associated virus inverted terminal repeat” or “AAV ITR” refers to a region adjacent to each end of the AAV genome that functions together on the same side as an origin for DNA replication and as a viral packaging signal. As used herein, “AAV ITR” does not necessarily include wild-type polynucleotide sequences that are modified, for example, by nucleotide insertions, deletions, or substitutions. Furthermore, AAV ITRs include, but are not limited to, AAV1, AAV2, AAV3, AAV4, AAV5, AAV6, AAV7, AAV8, AAV9, AAV10, AAV11, AAV12, AAV13, AAV14, AAV15, AAV16, AAV-rh8, AAV-rh10, A AV-rh20, AAV-rh39, AAV-rh74, AAV-rhM4-1, AAV-hu37, AAV-Anc80, AAV-Anc80L65, AAV-7m8, AAV-PHP-B, AAV-PHP-EB, AAV-2.5, AAV-2tYF, AAV-3B The AAV vectors are derived from any multiple serotypes, including AAV-LK03, AAV-HSC1, AAV-HSC2, AAV-HSC3, AAV-HSC4, AAV-HSC5, AAV-HSC6, AAV-HSC7, AAV-HSC8, AAV-HSC9, AAV-HSC10, AAV-HSC11, AAV-HSC12, AAV-HSC13, AAV-HSC14, AAV-HSC15, AAV-TT, AAV-DJ / 8, AAV-Myo, AAV-NP40, AAV-NP59, AAV-NP22, AAV-NP66, or AAV-HSC16. Furthermore, the 5' and 3' ITRs adjacent to the selected polynucleotide sequences in the AAV vector do not have to be identical and do not have to be derived from the same AAV serotype or isolate, as long as they function as intended to enable, for example, the desired therapeutic or genome editing effect. Furthermore, AAV ITR modifications to the D element can encode or facilitate different configurations of the AAV genome, single-stranded AAV genome (i.e., ssAAV), or self-complementary AAV genome (i.e., scAAV).

[0034] Unless otherwise specified or the context makes clear, when used herein, the term “about” with respect to a number or range of numbers is understood to mean the specified number and ±10% of that number, or 10% below the listed lower limit and 10% above the listed upper limit for any range of values.

[0035] As used herein, “CpG dinucleotide,” “CpG site,” or “CpG” refers to a region of nucleic acid (e.g., DNA or RNA) where a cytosine nucleotide occurs adjacent to a guanine nucleotide in a linear nucleic acid sequence of nucleotides along its length, e.g., cytosine and guanine separated by only one phosphate group, or cytosine at the 5' end of a guanine nucleotide.

[0036] The terms “recipient,” “individual,” “subject,” “host,” and “patient” are used interchangeably herein and, in some embodiments, refer to any mammalian subject, particularly humans, to whom diagnosis, treatment, or therapy is desired. “Mammal” for treatment purposes refers to any animal classified as a mammal, including humans, domesticated and livestock, as well as laboratory, zoo, sports, or pet animals, such as dogs, horses, cats, cattle, sheep, goats, pigs, mice, rats, rabbits, guinea pigs, and monkeys. In some embodiments, the mammal is human. None of these terms require the supervision of a medical professional.

[0037] "Identity percentage," "identity %," or "sequence identity" refers to the degree to which two sequences (nucleotides or amino acids) have the same residues at the same positions in their alignment. For example, "The nucleotide sequence is X% identical to sequence number Y" refers to the identity percentage of the nucleotide sequence to sequence number Y, stating that X% of the residues in the nucleotide sequence are identical to the corresponding residues in the sequence disclosed in sequence number Y. A sequence that is said to be X% identical to a reference sequence may contain more nucleotide or amino acid residues than those identified in the reference sequence, but it must contain the sequence corresponding to the reference sequence. In most cases, the sequence in question contains the sequence corresponding to all identified reference sequences. Generally, computer programs are used for such calculations. Exemplary programs for comparing and aligning pairs of sequences include ALIGN, FASTA, GAPBLAST, BLASTP, BLASTN, or GCG.

[0038] "Polynucleotide" or "nucleic acid" are used interchangeably herein and refer to a chain of nucleotides of any length, including DNA or RNA. In some embodiments, nucleotides are deoxyribonucleotides, ribonucleotides, modified nucleotides or bases, and / or analogs thereof. Polynucleotides may include modified nucleotides such as methylated nucleotides and their analogs (e.g., increased CpG dinucleotides as described herein). Where present, modifications to the nucleotide structure are conferred before or after the assembly of the chain. In some embodiments, the sequence of nucleotides is interrupted by non-nucleotide components. In some embodiments, polynucleotides are further modified after polymerization, such as by conjugation with a labeling component. Other types of modifications include, for example, “cap” substitutions of one or more naturally occurring nucleotides with analogs, internucleotide modifications, e.g., those with uncharged bonds (e.g., methylphosphonates, phosphotriesters, phosphoamidates, carbamates) and those with charged bonds (e.g., phosphorothioates, phosphorodithioates), those containing pendant moieties, e.g., proteins (e.g., nucleases, toxins, antibodies, signal peptides, poly-L-lysine), those containing intercalators (e.g., acridine, psoralens), those containing chelating agents (e.g., metals, radioactive metals, boron, metal oxides), those containing alkylating agents, those having modified bonds (e.g., alpha-anomeric nucleic acids), and unmodified forms of polynucleotides. In some embodiments, any of the hydroxyl groups normally present in the sugar are, for example, substituted with a phosphonate group, a phosphate group, protected with a standard protecting group, activated to prepare further linkage to further nucleotides, or conjugated to a solid support. In some embodiments, the 5' and 3' terminal OH groups are phosphorylated or substituted with amine or organic capping groups of 1 to 20 carbon atoms. Other hydroxyls may also be derivatized to standard protecting groups.In some embodiments, polynucleotides also include analogous forms of ribose or deoxyribose sugars, such as 2'-O-methyl-, 2'-O-allyl, 2'-fluoro-, 2'-azidol-ribose, carbocic sugar analogs, α- or β-anomeric sugars, epimeric sugars such as arabinose, xylose or lyxose, pyranose sugars, furanose sugars, sedoheptulose, acyclic analogs, and base-deficient nucleoside analogs such as methylriboside. In some embodiments, one or more phosphodiester bonds are substituted with morphological linking groups. These alternative linking groups include, but are not limited to, embodiments in which the phosphate is substituted with P(O)S ("thioate"), P(S)S ("dithioate"), (O)NRi ("amidate"), P(O)R, P(O)OR', or CH2 ("formacetal"), where R or R' is independently a substituted or unsubstituted alkyl (1-20C), aryl, alkenyl, cycloalkyl, cycloalkenyl, or aralgyl, optionally containing H or an ether (-O-) bond. Not all bonds in the polynucleotide need to be identical. The foregoing description applies to all polynucleotides referred to herein, including RNA and DNA. In some embodiments, the nucleic acids or polynucleotides disclosed herein have a reduced number of CpG dinucleotides compared to their parental equivalents. In some embodiments, the nucleic acids or polynucleotides disclosed herein are depleted of CpG dinucleotides compared to their parental equivalents (i.e., all CpG dinucleotides are modified so that they are no longer CpG dinucleotides, or all CpG dinucleotides are deleted). In some embodiments, the nucleic acids or polynucleotides disclosed herein are increased in methylated CpG dinucleotides.

[0039] The term "pharmaceutically acceptable" refers to molecular entities and compositions that are physiologically tolerable in mammals, particularly humans or animal patients.

[0040] A "recombinant AAV vector (rAAV vector)" refers to a polynucleotide vector derived from AAV and containing one or more heterologous sequences (i.e., nucleic acid sequences not of AAV origin) adjacent to at least one AAV ITR. In some embodiments, such an rAAV vector, when introduced into a host cell that has (or expresses) appropriate helper polynucleotides or viruses and expresses AAV Rep and Cap gene products (i.e., AAV Rep and Cap proteins), replicates and packages into viral particles. When an rAAV vector is incorporated into a larger polynucleotide (e.g., in a chromosome or in other vectors such as plasmids used for cloning or transfection), this rAAV vector is called a "provector" and is "rescued" by replication and capsid formation in the presence of AAV packaging function and appropriate helper function.

[0041] As used herein, the term “treatment” (also “treat” or “treating”) means any administration of a substance or composition (e.g., an AAV vector as described herein) that partially or completely alleviates, improves, helps survive, inhibits, delays the onset, reduces the severity, and / or reduces the incidence of one or more symptoms, characteristics, and / or causes of a particular disease, disorder, and / or illness (e.g., cancer). Such treatment may be for subjects who do not show signs of the disease, disorder, and / or illness in question, or for subjects who show only initial signs of the disease, disorder, and / or illness. Alternatively, such treatment may be for subjects who show one or more established signs of the disease, disorder, and / or illness in question. In some embodiments, the treatment may be for subjects who have been diagnosed with the disease, disorder, and / or illness in question. In some embodiments, the treatment may be for subjects who are known to have one or more susceptibility factors that are statistically correlated with an increased risk of developing the disease, disorder, and / or illness in question.

[0042] As used herein, “operably linked,” “operably linked,” “operatably linked,” or their grammatical equivalents refer to the arrangement of genetic elements, such as promoters, enhancers, polyadenylated sequences, etc., where the action of a first genetic element (e.g., migration or activation) has some effect on a second genetic element. The effect on the second genetic element may, but does not have to be, the same type of action as that of the first genetic element. For example, two genetic elements are operationally linked if the migration of the first element causes the activation of the second element. For example, a regulatory element, which may include a promoter and / or enhancer, is operationally linked to a coding region if the regulatory element assists in the initiation of transcription of a coding sequence. Intervening residues may exist between the regulatory element and the coding region as long as this functional relationship is maintained.

[0043] As used herein, the terms “peptide,” “polypeptide,” or “protein” refer to a chain of amino acids. As used herein, the term “protein” further refers to a larger molecule containing one or more chains of amino acids, and in some embodiments, a protein fragment or domain or a full-length protein. Furthermore, as used herein, the term “protein” refers to either a linear chain of amino acids or a chain of amino acids that has been processed and folded into a functional protein. Protein structure can be divided into four distinct levels: (1) primary structure – referring to the sequence of amino acids in a polypeptide chain; (2) secondary structure – referring to regular local substructures on the polypeptide backbone, such as α-helices and β-sheets; (3) tertiary structure – referring to the three-dimensional structure in the case of monomeric and polymeric protein molecules; and (4) quaternary structure – referring to a three-dimensional structure that includes the aggregation of two or more individual polypeptide chains acting as a single functional unit. The use of peptide or polypeptide herein does not imply that a chain of amino acids is not a protein (i.e., a chain of amino acids having a secondary, tertiary, or quaternary structure).

[0044] As used herein, the term “wild type” refers to a naturally occurring form of organism, strain, gene, nucleic acid, vector, or vector component that is distinguishable from a mutant or variant form.

[0045] The recombinant adeno-associated virus (rAAV) vector disclosed herein Cytokines are regulators of innate and adaptive immunity that enable signal transduction within the immune system. Due to their ability to recognize and destroy cancer cells in the immune system, there is considerable interest in using cytokines for cancer treatment. However, current cytokine therapies exhibit negative characteristics, including toxicity from systemic administration, short half-lives, and a lack of specificity. Improvements in cytokine therapy for treating cancers (e.g., glioblastoma, metastatic brain tumors, uveal melanoma) are needed.

[0046] This specification provides compositions and methods for the delivery of a target cytokine payload via rAAV, enabling targeted, low-dose, and direct administration to tumors and the tumor microenvironment. Local tumor delivery and low-dose administration can result in reduced local and systemic toxicity, for example, by bypassing neutralizing antibodies generated during systemic administration of rAAV. Furthermore, the rAAVs described herein have longer half-lives, enabling long-term and sustained stable expression, and are also self-limiting, ceasing with tumor death via payload activity. The compositions and methods described herein can further provide reduction of nonspecific inflammation by being optimized immunologically and for vector integrity.

[0047] An exemplary workflow of the mechanism of rAAV described herein is found in Figure 1. The rAAV described herein enables local delivery to the tumor (1), which then leads to the expression of engineered cytokines and direct tumor cell lysis in tumor cells. As a result, inflammatory cytokines are released, triggering an innate immune response (3), activating macrophages and natural killer cells to clear the tumor and released AAV antigens, followed by an adaptive immune response (4). As a result, the tumor is rapidly cleared and local and systemic toxicity is reduced.

In some embodiments, the rAAV vector comprises increased methylation of CpG dinucleotides compared to a parental equivalent. In some embodiments, the rAAV vector comprises depletion of CpG dinucleotides compared to a parental equivalent. In some embodiments, the rAAV vector comprises a reduction in CpG dinucleotides and increased methylation of CpG dinucleotides. In some embodiments, CpG dinucleotides are depleted or reduced if one or more nucleotides of the CpG dinucleotide are replaced with one or more different nucleotides, resulting in the sequence no longer being a CpG dinucleotide sequence. In some embodiments, if CpG dinucleotides of an rAAV containing a coding sequence (e.g., for a regulatory element, a gene (e.g., a transgene), an antibiotic resistance gene, etc.) are replaced with one or more different nucleotides, the one or more nucleotides are selected so as to preserve the function of the coding sequence. In other words, if the coding sequence is a regulator such as a promoter or enhancer, the function of the promoter or enhancer is preserved, or if the coding sequence codes for a polypeptide, the amino acid sequence of the polypeptide and / or the polypeptide function are preserved.

[0060] In some embodiments, the rAAV vector includes a reduction in CpG dinucleotides compared to its parental equivalent. In some embodiments, the CpG dinucleotides are reduced by at least about 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or more than 99% compared to its parental equivalent.

In some embodiments, the CpG dinucleotide is reduced in the range of approximately 15% to approximately 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100%. In some embodiments, the CpG dinucleotide is reduced in the range of approximately 20% to approximately 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100%. In some embodiments, the CpG dinucleotide is reduced in the range of approximately 25% to approximately 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100%.

In some embodiments, CpG dinucleotides are reduced by at least approximately 75%.

[0061] In some embodiments, the rAAV vector involves CpG dinucleotide depletion compared to its parental equivalent. In some embodiments, CpG dinucleotides are reduced by the deletion of specific CpG dinucleotides. In some embodiments, CpG dinucleotides are reduced by substituting one or more nucleotides within a CpG dinucleotide to create a sequence that is not a CpG dinucleotide. In some embodiments, CpG dinucleotides are depleted by the deletion of all CpG dinucleotides. In some embodiments, CpG dinucleotides are depleted by substituting one or more nucleotides within each CpG dinucleotide to create a sequence that is not a CpG dinucleotide.

[0062] In some embodiments, the rAAV vector includes increased CpG dinucleotide methylation compared to the parental equivalent. In some embodiments, the CpG dinucleotide methylation is increased by at least about 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or more than 95% compared to the parental equivalent.

In some embodiments, the methylation of CpG dinucleotides increases in the range of about 15% to about 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100%. In some embodiments, the methylation of CpG dinucleotides increases in the range of about 20% to about 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100%. In some embodiments, the methylation of the CpG dinucleotide increases in the range of approximately 30% to approximately 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100%.In some embodiments, the methylation of CpG dinucleotides increases in the range of approximately 40% to approximately 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100%. In some embodiments, the methylation of CpG dinucleotides increases in the range of approximately 50% to approximately 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100%. In some embodiments, the methylation of CpG dinucleotides increases in the range of approximately 60% to approximately 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100%. In some embodiments, the methylation of CpG dinucleotides increases in the range of approximately 70%–75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100%. In some embodiments, the methylation of CpG dinucleotides increases in the range of approximately 80%–85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100%. In some embodiments, the methylation of CpG dinucleotides increases in the range of approximately 90%–95%, 96%, 97%, 98%, 99%, or 100%.

[0063] In some embodiments, the CpG dinucleotide is modified throughout the entire length of the provided rAAV vector (e.g., by reduction, depletion, and / or increased methylation). In some embodiments, the CpG dinucleotide is modified only in one or more significant portions or elements (e.g., regulatory elements, polynucleotides containing coding sequences, etc.) of the provided rAAV vector. This disclosure provides, among other things, the insight that when the CpG dinucleotide is modified within the coding sequence of the payload of interest, a particular polynucleotide encoding the payload of interest (e.g., a polynucleotide encoding one or more interferons such as IFNβ) exhibits superior therapeutic outcomes (e.g., increased efficacy, reduced toxicity, etc.). Thus, in one non-limiting example, the rAAV vector provided by this disclosure comprises a polynucleotide encoding an interferon, wherein the coding sequence of the interferon contains a modified CpG dinucleotide (e.g., reduction, depletion, and / or increased methylation) compared to its parental equivalent, but other elements in the adjacent nucleic acid do not have the modified CpG dinucleotide. In another non-limiting example, the rAAV vector provided by this disclosure comprises a polynucleotide encoding an interferon, wherein the interferon encoding sequence comprises a modified CpG dinucleotide (e.g., reduced, depleted, and / or increased methylation) compared to its parental equivalent, and one or more other polynucleotides in the rAAV vector comprises a modified CpG dinucleotide (e.g., a promoter, antibiotic resistance gene, minigene, and / or polynucleotide element as described herein).

[0064] Mini gene regulation In some embodiments, the regulatory element of this disclosure is an inductive regulatory element (e.g., an inductive system such as a splice modulator binding site and / or promoter). In some embodiments, the inductive regulatory element is a minigene. In some embodiments, the regulatory element is a constitutive regulatory element.

[0065] In some embodiments, recombinant adeno-associated virus (rAAV) vectors comprising a minigene containing a splice modulator binding site are described herein. In some embodiments, the minigene is located at the 5' end of a polynucleotide encoding the payload of interest. In some embodiments, the rAAV described herein comprises one or more (e.g., 1, 2, 3, 4, 5, 6, 7, 8) exons, introns, pseudoexons, fragments thereof, or combinations thereof.

[0066] In some embodiments, a minigene comprises a minimal gene fragment containing at least one exon and regulatory region, or a splice modulator site, necessary for controlling the expression of a downstream polynucleotide sequence. In some embodiments, a minigene comprises one or more (e.g., 1, 2, 3, 4, 5, 6, 7, 8) exons, introns, pseudoexons, fragments thereof, or combinations thereof. In many embodiments, the splice modulator site of a minigene controls the splicing outcome of the RNA transcript encoded by the minigene. In some embodiments, the splice modulator site induces the RNA transcript to a specific splicing outcome based on factors present in the context of a particular cell or tissue (e.g., splicing outcome 1 when the minigene is in a stem cell, splicing outcome 2 when the minigene is in a retinal cell, splicing outcome 3 when the minigene is in a kidney cell, etc.). In some embodiments, the splice modulator site induces the RNA transcript to a specific splicing outcome by binding to a splice modulator, for example, in one or more nucleic acid sequences. In some embodiments, the splice modulator is a polypeptide, nucleic acid, or small molecule. In some embodiments, a minigene is used to control the expression of a downstream polynucleotide sequence by manipulating the minigene to allow (or activate) only the expression of the downstream polynucleotide sequence in the presence of a splice modulator and / or in the context of a particular cell type / tissue type.

[0067] In some embodiments, the minigene encodes an in-frame translation stop codon. In some embodiments, the in-frame translation stop codon is removed by alternative splicing of the minigene transcript. In some embodiments, alternative splicing of the minigene transcript modifies the transcript so that the stop codon is deleted or invalidated, an initialization or start codon is introduced, the open reading frame is restored, or a deleted portion of the protein is provided. In some embodiments, alternative splicing of the minigene transcript enables the transcription and translation of a downstream polynucleotide, for example, a polynucleotide encoding a payload of interest as described herein.

[0068] In some embodiments, the polynucleotide downstream of the minigene (e.g., a polynucleotide encoding the payload of interest as described herein) includes a translation termination codon. In some embodiments, the polynucleotide downstream of the minigene does not include a start codon. In some embodiments, the polynucleotide downstream of the minigene does not include an open reading frame.

[0069] In some embodiments, the minigene and the polynucleotide encoding the payload of interest are linked by a cleavable peptide. The cleavable peptide is a self-cleaving peptide, a drug-sensitive protease, or a substrate for an endogenous endoprotease.

[0070] In some embodiments, the minigene includes the nucleic acid sequence of SEQ ID NO: 31. In some embodiments, the minigene includes a nucleic acid sequence having at least 70% (e.g., 75%, 80%, 90%, 95%, 97%, 98%, or 99%) sequence identity to the nucleic acid sequence of SEQ ID NO: 31. In some embodiments, the minigene includes a nucleic acid sequence having at least 75% sequence identity to the nucleic acid sequence of SEQ ID NO: 31.

In some embodiments, the minigene includes a nucleic acid sequence having at least 97% sequence identity to the nucleic acid sequence of SEQ ID NO: 31. In some embodiments, the minigene includes a nucleic acid sequence having at least 98% sequence identity to the nucleic acid sequence of SEQ ID NO: 31. In some embodiments, the minigene includes a nucleic acid sequence having at least 99% sequence identity with respect to the nucleic acid sequence of SEQ ID NO: 31.

[0071] In some embodiments, the minigene includes the nucleic acid sequence of SEQ ID NO: 51. In some embodiments, the minigene includes a nucleic acid sequence having at least 70% (e.g., 75%, 80%, 90%, 95%, 97%, 98%, or 99%) sequence identity to the nucleic acid sequence of SEQ ID NO: 51. In some embodiments, the minigene includes a nucleic acid sequence having at least 75% sequence identity to the nucleic acid sequence of SEQ ID NO: 51. In some embodiments, the minigene includes a nucleic acid sequence having at least 80% sequence identity to the nucleic acid sequence of SEQ ID NO: 51. In some embodiments, the minigene includes a nucleic acid sequence having at least 90% sequence identity to the nucleic acid sequence of SEQ ID NO: 51. In some embodiments, the minigene includes a nucleic acid sequence having at least 95% sequence identity to the nucleic acid sequence of SEQ ID NO: 51. In some embodiments, the minigene includes a nucleic acid sequence having at least 97% sequence identity to the nucleic acid sequence of SEQ ID NO: 51. In some embodiments, the minigene includes a nucleic acid sequence having at least 98% sequence identity to the nucleic acid sequence of SEQ ID NO: 51. In some embodiments, the minigene includes a nucleic acid sequence having at least 99% sequence identity with respect to the nucleic acid sequence of SEQ ID NO: 51.

[0072] In some embodiments, the minigene is regulated by a small molecule splicing modifier. In some embodiments, the small molecule splicing modifier is sudemycin (FR901464, prazienolide B), LMI070, RG7916, or RG7800, and their derivatives.

[0079] In some embodiments, the small molecule splice modulator is an analogue of RG7916 or RG7800.

[0080] In some embodiments, the small molecule splice modulator is (5',Z)-5-(((lR,4R)-4-((2JE',4JE)-5-((3R,55')-7,7-dimethyl-l,6-dioxaspiro[2.5]octan-5-yl)-3-methylpenta-2,4-dien-l-yl)cyclohexyl)amino)-5-oxopenta-3-en-2-ylmethylcarbame Sudemycin is selected from the group consisting of (5',Z)-5-(((lR,4R)-4-((2JE',4JE)-5-((3R,55')-7,7-dimethyl-l,6-dioxaspiro[2.5]octan-5-yl)-3-methylpenta-2,4-dien-l-yl)cyclohexyl)amino)-5-oxopenta-3-en-2-yldimethylcarbamate.

[0081] In some embodiments, the small molecule splice modulator is a prazienolide compound. An example of a prazienolide compound is (8E,12E,14E)-7-((4-cycloheptylpiperazine-l-yl)carbonyl)oxy-3,6,16,21-tetrahydroxy-6,10,12,16,20-pentamethyl-l8,l9-epoxytricosa-8,l2,l4-triene-ll-olido, also known as E7107, which is a semi-synthetic derivative of the natural product prazienolide D.

[0082] In some embodiments, the minigene is regulated by an intracellular disease state. In some embodiments, the disease state is cancer. In some embodiments, the cancer is glioblastoma.

[0083] In some embodiments, the minigenes are regulated by cell type or tissue type.

[0084] Target payload In certain embodiments, polynucleotides encoding the payload of interest are described herein. In some embodiments, the payload of interest is a therapeutic agent, such as a therapeutic polypeptide.

[0085] In some embodiments, a therapeutic agent is any agent that, when administered to an organism, elicits a desired pharmacological effect. In some embodiments, an agent is considered a therapeutic agent if it exhibits a statistically significant effect across a suitable population. In some embodiments, a suitable population is a population of model organisms. In some embodiments, a suitable population is defined by various criteria such as a specific age group, sex, genetic background, or pre-existing clinical condition. In some embodiments, a therapeutic agent is a substance that can be used to alleviate, improve, reduce, inhibit, prevent, delay the onset of, reduce the severity of, and / or reduce the incidence of one or more symptoms or characteristics of a disease, disorder, and / or illness. In some embodiments, a therapeutic agent is an agent that has been approved or requires approval by a government agency before it can be marketed for administration to humans.

[0182] In some embodiments, the vector is a pseudotyped rAAV vector. The pseudotyped vector includes an AAV genome vector of a given serotype that has been pseudotyped with a Cap gene product derived from a serotype other than the given serotype (e.g., particularly AAV1, AAV3, AAV4, AAV5, AAV6, AAV7, AAV8, or AAV9). For example, a typical pseudotyped vector is an AAV serotype 2 genome vector that has been pseudotyped with a Cap gene product derived from AAV serotype 9.

[0183] In some embodiments, AAVs have intravirion mutations used to transduce specific cell types more efficiently than unmutated capsid virions. In some embodiments, preferred AAV variants have ligand insertions to facilitate AAV targeting to specific cell types. In some embodiments, construction and characterization of AAV capsid variants, including insertion variants, alanine screening variants, and epitope tagged variants, are used.

[0184] In some embodiments, artificial AAV capsids are used. Such artificial capsids are generated by any suitable technique that combines a selected AAV sequence (e.g., a fragment of the VP1 capsid protein) with a heterologous sequence derived from a non-AAV virus or non-viral source, obtained from a discontinuous portion of the same serotype, or obtained from a separately selected AAV serotype. Artificial AAV serotypes are, but are not limited to, pseudotyped AAV, chimeric AAV capsids, recombinant AAV capsids, engineered AAV capsids, or "humanized" AAV capsids.

[0185] Other rAAV virions used in the compositions and methods of this disclosure include, but are not limited to, capsid hybrids produced by molecular breeding of the virus, as well as those capsid hybrids produced by exon shuffling, directed evolution, rational design, error-prone PCR, via computational algorithms, or via the use of artificial intelligence or machine learning.

[0186] In some embodiments, the capsid is modified to improve therapeutic effects. In some embodiments, the capsid is modified for minimizing immunogenicity and / or immunocloaking, better stability and / or particle durability, efficient degradation, and / or precise delivery of heterogeneous coding sequences or functional fragments or variants to the nucleus. In some embodiments, the modification or mutation is a deletion, insertion, substitution, or any combination thereof of amino acids in the capsid polypeptide. In some embodiments, the capsid polypeptide contains 1, 2, 3, 4, 5, up to 10, or more amino acid substitutions and / or deletions and / or insertions. In some embodiments, one or more amino acid substitutions are introduced into one or more of VP1, VP2, or VP3. In one embodiment, the modified capsid polypeptide contains 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15 conservative or non-conservative substitutions relative to the wild-type polypeptide.

The cell line is screened to select a lead clone for recombinant vector production and, in some embodiments, is expanded into a production bioreactor and infected with a helper polynucleotide (e.g., wild-type adenovirus) as a helper to initiate vector production. In some embodiments, the recombinant viral vector (e.g., rAAV) is then recovered, the adenovirus is inactivated and / or removed (e.g., by heat), and the viral particles are purified. In some embodiments, the recombinant viral vector is purified and formulated.

[0192] In some embodiments, media suitable for the production of recombinant vectors are used. These media include, but are not limited to, modified Eagle medium (MEM), Roswell Park Memorial Institute medium (RPMI) 1640, Eagle minimal essential medium (EMEM), Ham F10 medium, Iskov modified Dulbecco medium (IMDM), Neuralbasal medium, Dulbecco modified Eagle medium (DMEM), and custom formulations, particularly those used for the production of recombinant vectors, manufactured by Hyclone Laboratories and JRH.

[0193] In some embodiments, suitable production culture media of this disclosure are supplemented with serum or serum-derived recombinant protein at levels of 0.5–20 (v / v or w / v). In some embodiments, the vector is produced under serum-free conditions, also known as a medium without animal-derived products. In some embodiments, commercially available or custom media are designed to support vector production and include, but are not limited to, supplementation with glucose, vitamins, amino acids, and other growth factors to increase the titer and / or yield of the vector in production cultures.

[0194] Vector-producing cultures involve various conditions (such as a wide temperature range and varying durations) suitable for the specific host cells being used. Vector-producing cultures include adhesion-dependent cultures cultured in suitable adhesion-dependent culture vessels such as plates, flasks, cell stacks, roller bottles, hollow fiber filters, microcarriers, and packed-bed or fluidized-bed bioreactors. In some embodiments, vector-producing cultures include suspension-adapted host cells such as HeLa, HEK-293, HEK-293T, HEK-293S, CHO, NS0, PER.C6, BHK, S2, and Sf9 cells, cultured in various methods including, for example, spinner flasks, agitated tank bioreactors, single-use bioreactors such as Cytiva Xcellerex, Sartorius, and Wave, as well as disposable systems.

[0195] In some embodiments, the viral particles of the present disclosure are recovered by lysing host cells of a vector-producing culture, or by collecting the culture supernatant from a producing culture, under conditions that allow the cells to release the viral particles into the culture medium in an intact state. Preferred methods for lysing cells include, for example, multiple freeze / thaw cycles, sonication, microfluidic treatment, and treatment with chemicals such as detergents and / or proteases.

[0196] In further embodiments, the virus particles are purified. As used herein, the term “purified” includes preparations of virus particles from which at least some of the other components present in the naturally occurring state of the virus particles or in the initially prepared state have been removed. Thus, for example, in some embodiments, isolated virus particles are prepared using purification techniques to concentrate from a source mixture, such as a culture lysate or a productive culture supernatant. In some embodiments, concentration is evaluated in various ways, measured by the proportion of DNase-resistant particles (DRPs) or genome copies (gc) present in the solution, or by infectivity, or in relation to second potentially interfering substances present in the source mixture, such as contaminants and impurities, including product-derived and process-derived impurities.

[0197] In some embodiments, the recovered product of the vector-producing culture is clarified to remove host cell debris. In some embodiments, the recovered product of the culture is clarified by filtration through a series of depth filters, including, for example, a Grade DOHC Millipore Millistak+HC pod filter, a Grade A1HC Millipore Millistak+HC pod filter, and an Opticap XL 10 Millipore Express SHC hydrophilic membrane filter, which is a 0.2 μm filter. Clarification can also be achieved by various other standard techniques, such as centrifugation or filtration through any cellulose acetate filter with a pore size of 0.2 μm or larger.

[0198] In some embodiments, the recovered vector-producing culture is further treated with a nuclease (e.g., DNA or RNA nuclease) to digest any high molecular weight DNA present in the product culture. In some embodiments, nuclease digestion is carried out under standard conditions.

In some embodiments, these steps are used individually, in various combinations, or in different orders. In some embodiments, the method includes all steps in the order described below.

[0200] Methods for generating recombinant vectors are described herein, the methods comprising the step of providing cells transfected with helper polynucleotides. In some embodiments, cells are transfected with helper polynucleotides that provide helper functions to AAV. In some embodiments, the helper polynucleotides provide adenoviral functions including, for example, E1A, E1B, E2A, E4ORF6, and / or VA RNA. The sequences of adenoviral genes that provide these functions are obtained in some embodiments from any known adenovirus serotype such as serotypes 2, 3, 4, 5, 7, 12, and 40, and further include any human type currently identified. In some embodiments, the adenoviral functions are provided by self-attenuating adenoviruses. In some embodiments, the method comprises transfecting cells with a vector expressing one or more genes necessary for AAV replication, AAV gene transcription, and / or AAV packaging.

[0201] Methods for generating recombinant vectors are described herein, the methods comprising the step of providing cells transfected with helper polynucleotides under the control of a promoter. In some embodiments, the cells are stable host cells containing the required(s) components under the control of an inductive promoter. In some embodiments, the cells are stable host cells containing the required(s) components under the control of a constitutive promoter. In some embodiments, the cells are stable host cells containing selected components under the control of a constitutive promoter and other selected components under the control of one or more inductive promoters. For example, stable host cells are generated that are derived from HEK-293 cells (containing E1 helper function under the control of a constitutive promoter) but containing Rep and / or Cap proteins under the control of an inductive promoter.

[0202] In some embodiments, the minigene, Rep sequence, Cap sequence, and helper function required to produce the rAAV of this disclosure are delivered to the packaging host cell in the form of any genetic element that transfers the sequences.

In some embodiments, adenovirus helper factors such as E1A, E1B, E2A, E4ORF6, and VA RNA are provided by either adenovirus infection or by transfecting producer cells with a third plasmid that provides adenovirus helper polynucleotides. In some embodiments, the producer cells are HEK-293 cells. In some embodiments, the helper polynucleotides provided vary depending on the producer cells used and whether those producer cells already carry some of these helper polynucleotides.

[0206] In some embodiments, the rAAV vectors described herein are produced by a triple transfection method, such as the exemplary triple transfection method provided below. In some embodiments, a plasmid containing the Rep gene and the Cap gene is transfected with a helper adenovirus plasmid into a cell line (e.g., HEK-293 cells) (e.g., using squeeze poration, lipofection, optical transfection, calcium phosphate method, or polyethyleneimine (PEI)), the virus is recovered, and optionally purified.

[0207] In some embodiments, the rAAV vector is produced by a producer cell line method, such as the exemplary producer cell line method provided below. Briefly, a cell line (e.g., HEK-293 cell line) is stably transfected with a plasmid containing the Rep gene, the Cap gene, and the promoter-payload sequence. The cell line is screened to select a lead clone for rAAV production and then expanded into a production bioreactor and infected with an adenovirus (e.g., wild-type adenovirus) as a helper to initiate AAV production. The virus is then recovered, and the adenovirus may be inactivated (e.g., by heat) and / or removed, and the rAAV is purified.

Exemplary combinations of nucleic acid elements are provided in Table 1, and each combination of nucleic acid elements was incorporated into its respective plasmid vector (plasmids 1–30, see also Figures 5A–5D) and subjected to assays (e.g., for interferon delivery). The nucleic acids were tested using a CAG promoter and included the CMV earliest enhancer element (CMVie) sequence, chicken beta-actin sequence, and rabbit beta-globin splice acceptor. The CMVie sequence used was cleaved and contained either a long (SEQ ID NO: 25), medium (SEQ ID NO: 26), or short (SEQ ID NO: 27) version. Incorporation of minigenes or "Xon" systems is further shown (SEQ ID NOs: 31 and 51).

[0237] [Table 1-1]

[0238] [Table 1-2]

[0239] material and method Figure 6 shows an exemplary workflow for producing an engineered plasmid (by cloning) used to produce an rAAV vector, which is provided in this disclosure and illustrates a multi-step cloning strategy for plasmid production. An exemplary protocol for producing a specific engineered rAAV vector is provided below.

[0240] To generate plasmid #1 (Figure 5A), a 582 bp novel synthetic hIFNβ-CpGdel polynucleotide was subcloned to an AAV-CAG-mCardinal polynucleotide using standard cloning techniques, with KpnI and EcoRI restriction enzymes instead of the mCardinal protein fluorescent marker ORF. To generate plasmid #12 (Figure 5L), two novel polynucleotide fragments were synthesized to cover both the bGH polyA sequence (SEQ ID NO: 34) and the CpG-depleted KanR via the CMV early enhancer sequence (SEQ ID NO: 35), and inserted into plasmid #1 using homologous recombination techniques. Plasmid #14 (Figure 5N) was constructed by inserting a 657 bp novel synthetic polynucleotide (SEQ ID NO: 54) into plasmid #12. Plasmids #18 (Figure 5R) and #16 (Figure 5P) were generated by substituting the hIFNβ-CpG ORF with a newly synthesized fragment for eGFP from plasmids #12 and #14, respectively, using BamHI / EcoRI. Plasmids #20 (Figure 5T) and #21 (Figure 5U) were obtained by substituting the hIFNβ-CpGdel ORF with a newly synthesized polynucleotide encoding mCardinal in plasmids #12 and #14, respectively. Plasmids #13 (Figure 5M) and #15 (Figure 5O) were constructed by inserting a newly synthesized polynucleotide fragment containing a splicing minigene (Xon) and a modified hIFNβ-CpGdel fragment that does not contain ATG and an alternative start codon into plasmids #12 and #14, respectively. Modified, newly synthesized eGFP fragments (without ATG and alternative start codon) were inserted in place of hIFNβ-CpGdel in plasmids #13 and #15 to construct plasmids #17 (Figure 5Q) and #19 (Figure 5S), respectively. Modified, newly synthesized mCardinal fragments (without ATG and alternative start codon) were inserted in place of hIFNβ-CpGdel in plasmids #13 and #15 to construct plasmids #22 (Figure 5V) and #23 (Figure 5W), respectively.

[0241] Example 2. Fabrication of an improved AAV This example describes the construction of an improved AAV with various combinations of regulatory elements for delivering the target gene to target cells.

[0242] In short, AAV strains were generated using a standard triple transfection protocol combined with pRepCap and an adenovirus helper plasmid. The platform process utilized the triple transfection protocol for adherent HEK293T cells, followed by one-step purification using density gradient ultracentrifugation to remove empty AAV capsids. The samples were then concentrated and formulated in a one-step process using a spin column. These research-grade lots were then formulated in AAV-compatible excipients (1X dPBS / 0.005% poloxamer). The vector genome (vg) titer of each lot was tested by RT-qPCR using an ITR primer set within the AAV ITR, and the results are provided in the certificate of analysis. AAV preparations #5, #6, #8, and #15 were produced using an established GMP-like large-scale manufacturing suspension platform (using suspension-adaptive HEK293 cells). The produced AAVs are listed in Table 2.

[0243] [Table 2]

[0244] These results confirm that all AAVs were produced with high viral genome titers (>1e13vg / mL), that the newly designed genome is suitable for AAV packaging and transduction experiments, and that it produces robust and clinically relevant levels of virus.

[0245] Example 3. Verification of various variants of therapeutic AAV candidates. This example describes the construction of an improved AAV for delivering the target gene to target cells, as well as the expression and payload activity regulated by various combinations of regulatory elements.

[0246] The productivity and functionality of various candidates of variations within the payload and different regulatory elements were evaluated. In four constructs, the variables tested included a CpG-depleted payload, two lengths of variation of the CAG promoter, and variable polyA sequences and antibiotic resistance cassettes. AAV preparations were tested in parallel in a series of assays to quantify viral potency using 1) vector genome titers by digital PCR (dPCR) using payload primers, 2) capsid titers using a commercially available ELISA kit, and 3) an in vitro cell-based assay measuring the expression of the payload after transduction in mammalian cells. The percentage of full capsids and volumetric yields of AAV were calculated using vg titers and capsid titers, and the data presented as relative ratios between various production lots are shown in Table 3, with AAV#6 used as an internal reference for all values tested simultaneously. For viral potency, ratios between production lots were calculated using values obtained at an MOI of 5e5 vg / cell for each construct.

[0247]

Table 3

[0248] These results demonstrated that the various elements used in combination within the AAV genomic plasmid did not have a significant impact on AAV productivity or activity.

[0249] Example 4. Large-scale AAV batches for evaluating clinical manufacturing suitability This example describes the production of large-scale batches of improved AAV with various combinations of regulatory elements for delivering a gene of interest to target cells.

[0250] Candidates with therapeutic payloads were produced using a large-scale suspension platform. AAV batches were produced in both 2L and 4L scales, fully purified, and evaluated against various quality criteria. AAV batches were purified through a multi-step process to ensure high levels of purity in the final AAV material. The process included tangential flow filtration (TFF), affinity capture chromatography, gradient ultracentrifugation or anion exchange chromatography, and final formulation using a centrifuge or another TFF. AAV strain genome titers were obtained using PCR-based protocols. These AAV preparations were used to evaluate various critical quality characteristics in parallel experiments.

[0251] As representative examples of AAVs described herein that have a therapeutic payload, plasmid 1 (Table 4) or plasmid 24 (Table 5) were used for the tests. AAV preparations were tested in parallel in a series of assays to quantify viral potency using 1) vector genome titer by digital PCR (dPCR) with primers located within the therapeutic payload, 2) capsid titer using a commercially available ELISA kit, and 3) in vitro cell-based assays measuring the expression of the transduced payload in mammalian cells. The percentage and volume yield of AAVs with full capsids were calculated using vg and capsid titers, and the collected data, expressed as relative ratios between various production lots, are shown in Tables 4 and 5, with AAV preparation #5 (Table 4) or AAV preparation #6 (tested in parallel without the capsid; Table 5) used as internal references, respectively. For viral potency, the ratios between production lots were calculated using values ​​obtained at an MOI of 5e5vg / cell for each construct in the experiments presented in Table 4. Regarding viral efficacy, the ratio between production lots was calculated using the values ​​obtained at an MOI of 3.9e5vg / cell for each construct in the experiments presented in Table 5.

[0252] [Table 4]

[0253] [Table 5]

[0254] The purity and presence of AAV capsid proteins were confirmed in the expected ratios in several AAV preparations. In short, a total of 1 e11 vg of each preparation was evaluated by gel electrophoresis under denaturing conditions, followed by Coomassie blue staining (Figure 7). In each preparation, the three capsid proteins (VP1, VP2, and VP3) were identified in the expected ratio of approximately 1:1:10, and no other proteins were detected, confirming high purity and the absence of detectable impurities or contaminants.

[0255] These results demonstrate orthogonal validation of the production capabilities of therapeutic AAV candidates (each candidate produced by a different manufacturing vendor) and highlight inter-facility availability and robust production processes across users and different stages of the process. All minor variations observed between different production service providers were within the expected range for small-batch production.

[0256] In summary, these successful cloning experiments and virus production demonstrated the high purity and uniformity of high-titer viral genomes (>1e13 vector genome (vg) / mL) in each AAV construct, the suitability of the newly designed genomes for AAV packaging and transduction experiments, and robust and clinically relevant levels of virus production.

[0257] Example 5: Parallel production of improved AAV variants for validation of AAV vectors with therapeutic payloads This embodiment describes a comparison of the functionality and packaging of different AAV vectors with therapeutic payloads.

[0258] In short, HEK293 cells (VPC2.0 cells, ThermoFisher Scientific) grown in suspension were individually transfected for each pAAV plasmid with pRepCap and pAd helper plasmids to support the packaging of the AAV genome. Upon production, the cells were lysed and subjected to nuclease digestion (benzonase), and the crude lysate was clarified by centrifugation to remove cell membranes and debris. The viral preparations were cryopreserved until vg titer testing was performed using a digital dPCR protocol with primers and probe sets specific to each payload (Figures 8A-8C).

[0259] In summary, these studies demonstrated successful virus production for each AAV construct at titers within the expected range (>1e10vg / mL), the suitability of the newly designed genome for AAV packaging and transduction experiments, and clinically relevant levels of virus production.

[0260] Example 6: Demonstration of the efficacy of an AAV with a therapeutic payload. This embodiment describes the effectiveness of payloads delivered by AAVs as described herein.

[0261] In short, HEK293T cells were seeded in 96-well plates and transduced using multiple variants of AAV-CAG-hIFNβ to achieve infection multiplicity ranging from approximately 3e4 to 1e6 vg / cell. 48 hours after transduction, the supernatant was collected for payload analysis. The amount of hIFNβ was measured in nanograms / milliliter (ng / mL; Figures 9A-9D) or picograms / milliliter (pg / mL; Figure 9E) using commercially available ELISA kits for human (h)IFNβ (Figures 9A-D) or mouse (m)IFNβ (Figure 9E).

[0262] Specifically, in the first experimental set, all preparations carried the hIFNβ payload and were packaged within the same AAV capsid serotype but were produced from plasmid #1 produced by four different vendors (Figure 9A). Analyzing the results, it was observed that when produced by a specific vendor (AAV preparation #6), the potency was lower. However, as shown previously, no other differences were detected. All other preparations (#5, #8, and #9) generated from plasmid 1 demonstrated similar potencies as measured by payload expression.

[0263] In a series of experiments, plasmid #7 (corresponding to AAV preparation #1 in Figure 9B or AAV preparation #3 in Figure 9D), plasmid #1 (corresponding to AAV preparation #9 in Figure 9B or AAV preparation #6 in Figure 9D), plasmid #12 (corresponding to AAV preparation #10 in Figure 9B), and plasmid number #14 (corresponding to AAV preparation #11 in Figure 9B), produced by the same vendor and internally packaged with the same AAV capsid serotype, showed no significant differences in their potencies among multiple variants of our AAV constructs and payloads, excluding preparation #6 shown in Figure 9A.

[0264] AAVs carrying payloads other than IFN did not result in measurable IFN expression, as expected. It was also demonstrated that AAV preparation #15 was one of those showing the highest level of potency among constructs and vendors (AAV preparation #15 was prepared by a process similar to the one used for clinical batch production).

[0265] In a series of experiments, comparing human (h) and mouse (m) cytokine payloads, it was demonstrated that mouse cytokines can be expressed in human cells (Figure 9E), thus demonstrating that such payloads can be used as controls in various in vitro and in vivo models.

[0266] In summary, these results demonstrate that the AAV described herein can successfully deliver functional therapeutic payloads, such as hIFNβ or mIFNβ, to mammalian cells.

[0267] Example 7: Demonstration of payload activity during delivery in mammalian cells This embodiment describes the activity of the payload delivered by the AAV described herein.

[0268] An activity assay using a reporter cell line was employed to measure the therapeutic transgene activity. This method utilized a reporter cell line (U937) of human premonocytes engineered to express Firefly Luciferase under the control of an IFNα / β-responsive promoter. In this model, when IFNα or IFNβ binds to the IFNα / β receptor (IFNAR1) on the cell surface, the IFNα / β-regulated Firefly Luciferase reporter gene construct is activated, resulting in a precisely quantifiable luminescence signal.

[0269] In short, AAV preparations were incubated with reporter cells at an MOI of 5e5vg / cell. AAV preparation #12 (expressing the reporter payload mCardinal) and cell culture medium (NC) were used as negative controls. Measurements were performed after an 18-hour incubation period at 37°C and 5% CO2. A standard curve was generated using commercially available recombinant hIFNβ1 cytokine (Prospect CYT-234) and expressed in infectious units / mL. Luciferase detection and measurement were performed using a reporter detection assay (Figure 10). These results demonstrated that various hIFNβ payloads were successfully expressed and biologically active in target cells. The data also correlated with efficacy measurements by payload expression, shown in Figures 9A–9E, with preparations #10 and #13 showing the highest activity and expression (Figure 9C), and preparation #6 showing the lowest activity and expression (Figures 9A and 9D).

[0270] In summary, these data demonstrate the functionality of the vector described herein in successfully delivering biologically active hIFNβ during transduction into human cells in an in vitro model.

[0271] Example 8: Therapeutic activity of AAV with therapeutic payload in cancer cells This embodiment describes the therapeutic activity of the payload delivered to cancer cells (e.g., brain tumor cells, e.g., brain tumors that have metastasized from primary cancer originating in other parts of the body) by the AAV described herein.

[0272] Patient-derived xenograft organoid (PXDO) models were established from secondary breast cancer that had metastasized to the brain, and the resulting organoids were used to monitor the antitumor effect of AAV with a therapeutic payload. Organoids were established by qualified manufacturing vendors using proprietary methods. Before seeding onto hydrogels, organoids were exposed to small amounts of culture medium for 2–4 hours with three doses of AAV preparation #6 (expressing hIFNβ) and an AAV-negative control expressing GFP (AAV-GFP). Untreated organoids were exposed to culture medium only. In addition to AAV administration, replication wells were included with 1 μm staurosporine as a positive killing control or AAV preparation buffer as a negative killing control. Six days after administration, cell viability was evaluated in four replication wells (n=4) under each treatment condition using a reporter assay (Promega G7570). Total viable cells were measured by generating a luminescence signal as luminescence (lux), which is directly proportional to the amount of ATP in culture and, consequently, the number of cells. Organoids obtained from the technical replication wells for each treatment condition were further collected, fixed, washed with PBS, and stained with Hoechst and Rhodamine Phalloidin to stain the cytoskeleton of the nucleus and eukaryotic cells, respectively. The stained organoids were imaged at 4x magnification and subsequently subjected to high-content imaging analysis using the 3D analysis platform Ominer® to quantify the effect of the compounds on tumor growth.

[0273] As shown in Figure 11, a dose-dependent decrease in organoid viability 6 days after infection was observed with AAV-hIFNβ infection, but not with AAV-GFP. In the AAV-hIFNβ-treated group, a time-dependent decrease in cell viability was observed at all tested viral concentrations. In the AAV-GFP-treated group, no significant changes were observed in any high-content imaging indicator at 6 days after treatment, indicating that AAV-GFP treatment did not have a therapeutic effect on this model at the tested doses. In organoids treated with AAV-hIFNβ, a dose- and time-dependent increase in the percentage of dead cells was observed, and furthermore, a significant decrease in total organoid size and number of nuclei per organoid was observed at all dose levels of AAV-hIFNβ. Compared to untreated and buffered organoids, AAV-IFNβ treatment showed a slight decrease in organoid number, number of nuclei, and total nuclear size at the highest viral dose tested.

[0274] These results demonstrated that the hIFNβ payload was normally expressed in target cancer cells (e.g., target brain tumor cells derived from primary cancer metastasized from other parts of the body), was biologically active, and therapeutically effective in treating cancer. Taken together, these results showed that AAV-hIFNβ induced an antitumor effect, primarily based on cytotoxicity, which was particularly pronounced at the highest dose levels tested. The data demonstrated that AAV-hIFNβ has the ability to induce antitumor activity in an ex vivo model of human tumor cells with brain metastases.

[0275] Example 9. Extended AAV delivery payload expression in GBM cancer cells This embodiment describes the therapeutic activity of the payload delivered to brain tumors by the AAV described herein.

[0276] In this example, immortalized glioblastoma (GBM) cells were exposed to either an AAV expressing an hIFNβ payload as described herein, or a recombinant hIFNβ cytokine (unvectorized). After exposure, hIFNβ levels were monitored in cell culture medium for 4 days.

[0277] In short, cells were seeded in 48-well plates and exposed to AAV preparation #13 (hIFNβ, 4e5vg / cell) or AAV preparation #12 (mCardinal, 4e5vg / cell) at a predetermined MOI. Complete culture medium changes were performed daily for a total of four days. Negative control wells were exposed to AAV expressing the fluorescent protein mCardinal (preparation #12) as a control, and to a medium without the activator. hIFNβ levels were measured from the collected supernatant using a high-sensitivity hIFNβ ELISA kit (PBL catalog number 41415).

[0278] The secreted hIFNβ levels were quantifiable as early as 10 hours after transduction, with peak expression observed at 72 hours and maintained up to 96 hours. AAV transduction alone did not stimulate therapeutic levels of hIFNβ secretion from GBM cells in vitro, as evidenced by the low levels of hIFNβ from AAV-mCardinal transduction cells. Indeed, the supernatant from AAV-mCardinal-treated cells was below the quantification limit of the measurement method in all four samples at 24 hours, all four samples at 48 hours, two samples at 72 hours, and three samples at 96 hours. On the other hand, none of the three copies that showed detectable levels in this experiment (plotted in Figure 12) exceeded 5 pg / mL.

[0279] In summary, the results demonstrate that the AAV described herein can be successfully transduced into human GBM cells to deliver a sustained hIFNβ payload.

[0280] Example 10. Production and testing of clinical-grade therapeutic AAV to initiate a Phase I / II clinical trial in brain tumor patients. This example describes the construction of clinical-grade AAVs with various combinations of regulatory elements for delivering the target gene.

[0281] AAVs containing a therapeutic payload were produced in plasmid batches in accordance with Good Manufacturing Practices (cGMP) regulations. Plasmid batches were used to produce the viral drug. An exemplary cGMP-compliant manufacturing process is shown in Figure 13.

[0282] To produce cGMP-compliant plasmid batches, master cell banks (MCBs) were created for the plasmids described herein, such as the long CMVie, short CBA, CpG-deleted hIFNβ payload, mutant WPRE, bGH polyA, and plasmid #24 with a CpG-deleted kanamycin resistance gene. Furthermore, to enable optimal AAV production by transfection, E. coli strains are selected to produce plasmids that are high-quality, highly uniform, highly stable, and predominantly supercoiled. The generated plasmids are used to produce various GLP (Good Laboratory Practice) and GMP (Good Manufacturing Practice) grade AAV batches to support preclinical development, including but not limited to toxicity and clinical trials to enable IND (Indication of Diagnosis).

[0283] A series of highly specific assays have been developed to test AAV GLP and GMP-compliant batches. These assays are used to evaluate AAV pharmaceuticals to assess safety, potency, titer, and purity criteria, as well as other appropriate critical quality characteristics.
