The present disclosure relates to composition, methods, and processes for the preparation, use, and/or formulation of adeno-associated virus (AAV) particles comprising at least one element for the Vectorized Editing of Nucleic acids to correct Overt Mutations (VENOM).
Genetic engineering where DNA can be inserted, replaced, deleted or modified in the genome of a living organism is referred to as “genome editing,” “genome engineering,” or “gene editing”. Unlike early techniques that randomly inserted genetic material into a host genome, genome editing targets the insertions to site specific locations.
And while other genome editing technologies such as zinc finger (ZFNs), transcription activator-like effector nucleases (TALENs) and homing meganuclease have recently been utilized to edit DNA in hopes of repairing genomic defect, these suffer from lack of scalability, difficulty in individualized engineering and the expense of designing a unique complex for each locus to be altered. Additionally, work has to be done to define the optimized components of a system which will be effective in exploiting the cas9 CRISPR system as a tool for research, diagnostics and therapeutics with the ultimate goal of target-specific genome editing.
The present disclosure addresses the need for new technologies for treating genetic disorders caused by abnormalities in the genome whether heritable or acquired, monogenic or multifactorial, by providing AAV-based compositions and complexes which go beyond those of the art. Provided herein are recombinant adeno-associated virus particles having at least one element for the Vectorized Editing of Nucleic acids to correct Overt Mutations (VENOM).
For delivery of VENOM elements, an AAV is used as the delivery modality for a nucleic acid sequence encoding the VENOM elements, or a fragment thereof, which results in in vivo expression of the encoded payload. The mechanism underlying the vectorized delivery of VENOM elements is thought to proceed through the following steps. First, the vector genome enters the cell via endocytosis, then escapes from the endosomal compartment and is transported to the nucleus wherein the vector genome is released and converted into a double-stranded episomal molecule of DNA by the host. The transcriptionally active episome results in the expression of encoded VENOM elements that may then be secreted from the cell into the circulation. Therefore, AAV delivery of VENOM elements may therefore enable continuous, sustained and long-term delivery by a single injection of AAV particles.
The present disclosure provides compositions, methods and processes for the design, preparation, manufacture and/or formulation of recombinant adeno-associated virus (AAV) particles having at least one element for the Vectorized Editing of Nucleic acids to correct Overt Mutations (VENOM).

The CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)-Cas system is widely found in bacterial and archaeal genomes as a defense mechanism against invading viruses and mobile genetic elements such as bacteriophages and plasmids, which sometimes is called RNA-mediated adaptive immune system. A CRISPR locus in a bacterial genome is a DNA region with an array of short identically repeated sequences of generally 21-37 base pairs, separated by spacers with unique sequences of generally 20-40 base pairs. The CRISPR locus can be found on both chromosomal and plasmid DNA. The spacers are often derived from nucleic acid of invading viruses and plasmids, which can be used as recognition elements to find matching virus genomes or plasmid sequences and destroy them as part of defense system. CRISPR activity requires the presence of a set of CRISPR associated (cas) genes, which are usually found adjacent to the CRISPR array and encode CRISPR associated (Cas) proteins with a variety of predicted nucleic acid-manipulating activities such as nucleases, helicases and polymerases. The CRISPR-Cas system targets DNA and/or RNA as a way of protecting against viruses and other mobile genetic elements and can be developed for programmable genetic editing.
In bacteria, the CRISPR-Cas system relies on the activity of short mature CRISPR RNAs (crRNAs) that guide Cas proteins (e.g. Cas9) to silence invading nucleic acids. The crRNRs are processed from the DNA sequences clustered in the CRISPR array. The CRISPR array transcript, the precursor CRISPR RNA (pre-crRNA), is processed into individual short mature crRNAs. In the CRISPR-Cas type II system, a small, non-coding RNA molecule called trans-activating crRNA (tracrRNA), which has a sequence complementary to the identical repeat in the CRISPR, is required for crRNA maturation. The tracrRNA is encoded in the vicinity of the cas genes and CRISPR repeat-spacer array. Following the hybridization of tracrRNA to the short identical repeat in the pre-crRNA, the bacterial double-stranded RNA specific endoribonuclease, RNase III, processes/cleaves the pre-crRNA transcript to generate a dual-tracrRNA:crRNA that guides the CRISPR-associated endonuclease Cas9 (Csn1) to cleave site-specifically cognate target DNA.
In bacteria, CRISPR-Cas immunity operates in three steps with the principle that an intruder once memorized by the system will be remembered and silenced upon a repeated infection. During the initial adaptation phase, a part of an invading nucleic acid sequence is incorporated as a new spacer within the repeat-spacer CRISPR array and the infection is thus memorized. During the expression phase, the CRISPR array is transcribed as a pre-crRNA molecule that undergoes processing to generate short mature crRNAs, each complementary to a unique invader sequence. During the interference phase, the individual crRNAs guide Cas protein(s) to cleave the cognate invading nucleic acids in a sequence-specific manner for their ultimate destruction.
The CRISPR-Cas systems have recently been classified into three distinct types (I-III). Types I and III share some common features, with crRNAs and Cas proteins being the only known components required for the steps of expression and interference. In both types I and III, the mature crRNAs guide a complex of several Cas proteins to the cognate-invading nucleic acids and a Cas endonuclease of the ribonucleoprotein complex cleaves the target nucleic acids. Type II CRISPR-Cas has evolved distinct pre-crRNA processing and interference mechanisms, as described above. Pre-crRNA processing requires base pairing of every pre-crRNA repeat with a tracrRNA. The tracrRNA:crRNA duplex forms a ternary silencing complex in the presence of Cas9, the endonuclease of Type II CRISPR-Cas system.
Though naturally being identified as a defense mechanism in prokaryotes, the CRISPR-Cas system (e.g., the Type 11 CRISPR-Cas9 system) has been developed as a RNA-guided DNA targeting platform. It has been widely studied for the use of genomic editing and transcription modulation in eukaryotic cells, and has shown great potential in correcting mutations in human genetic diseases. As learned from the bacterial system, two distinct components are required in CRISPR-Cas based genome editing: (1) a guide RNA molecule, such as a tracrRNA:crRNA duplex and (2) an endonuclease, such as Cas9. When the guide RNA molecule and Cas9 are expressed in a cell, the guide RNA/Cas9 complex is recruited to the target sequence by the base-pairing between the guide RNA sequence and the target sequence in the genomic DNA. The recruited Cas9 cuts both strands of DNA causing a Double Strand Break (DSB). For successful location of Cas9 to the target sequence, the genomic target sequence must also contain the correct Protospacer Adjacent Motif (PAM) sequence immediately following the target sequence. Cas9 cuts 3-4 nucleotides upstream of the PAM sequence. A DSB can be repaired through one of two general repair pathways: (1) the Non-Homologous End Joining (NHEJ) DNA repair pathway, or (2) the Homology Directed Repair (HDR) pathway. The NHEJ repair pathway often results in inserts/deletions at the DSB site that can lead to frameshifts and/or premature stop codons, effectively disrupting the open reading frame (ORF) of the targeted gene. The HDR pathway requires the presence of a repair template, which is used to fix the DSB. HDR faithfully copies the sequence of the repair template to the cut target sequence. Specific nucleotide changes can be introduced into a targeted gene using HDR with a repair template.
The CRISPR-Cas9 system has been used as a tool to manipulate the genome in mammalian cells (i.e. eukaryotes). Vu et al (Wu et al., Science, 2013, 339: 819-823) and Mali et al (Mali et al., Science. 2013, 339: 823-826) first demonstrated that expressing a codon-optimized Cas9 protein and a guide RNA leads to efficient cleavage and short insertion/deletion of target loci, which could inactivate protein-coding genes by inducing frameshifts and/or creating premature stop codons. The CRISPR-cas system can be used to simultaneously edit more than one genes by delivering multiple guide RNAs (Yang et al., Cell, 2013, 154:1370-1379; and Jao et al., Proc Natl Acad Sci USA. 2013, 110:13904-13909); to introduce deletions and inversions of regions ranging from 100 bps to 1000000 bps on a chromosome (Xiao et al., Nucleic Acids Res., 2013, 41:e141; and Canver et al., J Biol Chem., 2014, 289(31): 21312-21324); to engineer chromosomal translocations between different chromosomes (Torres et al., Nat Commun. 2014, 5: 3964); to correct mutations in disease genes (Yin et al., Nat Biotechnol. 2014, 32(6): 551-553; Schwank et al., Cell Stem Cell. 2013, 13: 653-658; and Wu et al., Cell Stem Cell. 2013, 13: 659-662); and to introduce specific nucleotide modifications at the target sequence in combination with a DNA repair template containing the desired sequence but having a high degree of homology to the target sequence, for example, by cotransfection of the template DNA into the cell along with the guide RNA/Cas9 complex.
The CRISPR-Cas system has also been adapted to label proteins by introducing specific sequences such as HA-tag (Auer et al., Genome Res. 2014: 24:142-153). Other expended applications of the CRISPR-Cas system include site-specific imaging of endogenous loci in living cells, by using a fluorescent marker (e.g., GFP). In addition to human and rodent cells, the system has also been adapted to many other species, including monkey, pig, rat, zebrafish, worm, yeast, and several plants.
The CRISPR-Cas system is a remarkably flexible tool for genome manipulation. One of the primary advantages of this technology is that the nuclease activity and the DNA-binding activity of Cas9 are discrete functions in the protein. The Cas9 nuclease activity (cutting) is performed by 2 separate domains, RuvC and HNH. Each domain cuts one strand of DNA and each can be inactivated by a single point mutation. In S. pyogenes, a Cas9 D10A mutant has an inactive RuvC domain (RuvC−) and an active HNH domain (HNH+) and a Cas9 H840A mutant has an inactive HNH domain (HNH−) and an active RuvC domain (RuvC+). When both domains are inactive (D10A and H840A, RuvC− and HNH−) the Cas9 protein has no nuclease activity (catalytically inactive) and is said to be ‘dead’ (dCas9): however, the inactive dCas9 still retains the ability to bind to DNA based on guide RNA specificity. Such dCas9 protein may be used as a platform to recruit other functional proteins to a target DNA sequence.
The CRISPR-cas system may also be used to modulate transcription in a genome by introducing sequence specific control of gene expression. In some applications, a catalytically inactive dCas9 can be generated by mutating the two nuclease domains of Cas9, which can bind DNA without introducing cleavage or mutation. When targeted to a promoter, the nuclease-null dCas9 binding alone can interfere with transcription initiation, likely by blocking binding of transcription factors or RNA polymerases. When targeted to the non-template strand within the gene, the dCas9 complex blocks RNA polymerase II transcription elongation (Jinek et al., Science. 2012, 337(6096): 816-821; Qi et al., Cell. 2013, 152:1173-1183; and Gilbert et al., Cell. 2013, 154: 442-451). In other applications, the inactive or nuclease-null cas9 may be fused with effector domains with distinct regulatory functions, such as transcription repressor domains (e.g., the Krueppel-associated box (KRAB)) to lead to stronger silencing of mammalian genes (Gilbert et al., Cell, 2013, 154(2): 442-451), or with activator domains (e.g., VP64) to activate transcriptions (Larson et al., Nat Protoc. 2013, 8: 2180-2196). Such guide RNA based methods are referred to as CRISPR interference (i.e. CRISPRi) (Qi et al., Cell, 2013, 152: 1173-1183; and Larson et al., Nature Protocols, 2013, 8: 2180-2196). Such RNA based methods for regulation of gene expression in a genome-wide scale are also known as CRISPR interference ((i.e., CRISPR interference, CRISPRi).
In addition to modulating gene expression, the fusion of dCas9 with other heterologous effector domains could enable many other applications. For example, one could fuse catalytically inactive dCas9 with chromatin modifiers to change the epigenetic state of a locus (Mali et al., Nat Methods. 2013, 10:957-963: and Sander et al., Nat Biotechnol. 2014, 32: 347-355). dCas9 fused to an epitope tag(s) can be used to purify genomic DNA bound by the guide RNA. Building on the well-established concept of ChIP (Chromatin Immunoprecipitation), researchers have created enChIP (engineered DNA-binding molecule-mediated ChIP) that allows for the purification of any genomic sequence specified by a particular guide RNA. By creating pooled libraries of guide RNAs, the CRISPR-Cas system can be used in powerful genomic screening techniques or for nucleic acid enrichment (See, e.g., US patent publication NO.: 20140356867, the contents of which is herein incorporated by reference in its entirety).
Safe delivery of CRISPR/Cas endonucleases remains one of the major barriers to the widespread application of in vivo genome editing as with this type of viral delivery system, active endonucleases will remain in the retina for an extended period, making genotoxicity a significant consideration in clinical applications. One way to address this issue is to include a self-destructing “kamikaze” CRISPR/Cas system from Li et al. that disrupts the Cas enzyme itself following expression (Hum Gene Ther. 2019 Aug. 2. doi: 10.1089/hum.2019.021; the contents of which are herein incorporated by reference in their entirety). Li et al. initially designed four guide RNAs (sgRNAs) to target Streptococcus pyogenes Cas9 (SpCas9) and the selected sgRNAs were cloned into a dual AAV vector genome. One vector genome delivered SpCas9 and the other delivered sgRNAs directed against SpCas9 and the target locus. Both constructs were packaged into an AAV particle and/or VAP particle and intravitreally administered. Li et al found that a reduction of SpCas9 mRNA when the dual approached was used as compared to CRISPR/Cas alone. In some embodiments, the AAV particles and/or VAPs described herein may include a self-destructive “kamikaze” CRISPR/Cas system.
In some embodiments, the VENOM elements are CRISPR/Cas9 and they may be used to introduce mutations into a gene as a protection against a disease, disorder, and/or condition.
In some embodiments, the VENOM elements encoded in the AAV particle are Cas9, a DNA-targeting RNA, a targeter-RNA that hybridizes with a target sequence of the target DNA molecule and an activator-RNA that hybridizes with the targeter-RNA to form a double-stranded RNA duplex as described in U.S. Pat. No. 10,227,611, the contents of which are herein incorporated by reference in their entirety. As a non-limiting example, the targeter-RNA includes the 12-nucleotide crRNA sequence as described in U.S. Pat. No. 10,227,611 as SEQ ID NO: 679. As a non-limiting example, the activator-RNA includes the 67-nucleotide tracrRNA sequence as described in U.S. Pat. No. 10,227,611 as SEQ ID NO: 432.
Currently the most commonly used RNA-guided endonuclease for genome editing in the CRISPR-Cas system is the Type II CRISPR associated (Cas) nuclease. Cas9. The Cas9 nuclease is a DNA endonuclease with two nuclease domains, namely, the N-terminal RuvC-like nuclease (RNAse H fold) and the HNH (McrA-like) nuclease domain that is located in the middle of the protein, each cleaving each of the two DNA strands. When both of these domains are active, the Cas9 protein causes double strand breaks (DSBs) in the genomic DNA. In the absence of a suitable repair template, the DSB is repaired by the Non-Homologous End Joining (NHEJ) DNA repair pathway. During NHEJ repair, InDels (insertions/deletions) may occur as a small number of nucleotides are either inserted or deleted at random at the DSB site.
Cas9 may be inactivated with both the functional domains mutated ((RuvC− and HNH−), generating a nuclease-null Cas9 (dCas9). Cas9 may also be modified as “nickase: a Cas9 protein containing a single inactive catalytic domain, either RuvC− or HNH−. With only one active nuclease domain, the Cas9 nickase cuts only one strand of the target DNA, creating a single-strand break or ‘nick’. Similar to the inactive dCas9, a Cas9 nickase is still able to bind DNA based on guide RNA specificity, though nickases will only cut one of the DNA strands. A single-strand break, or nick, is normally quickly repaired through the HDR pathway, using the intact complementary DNA strand as the template. Two proximal, opposite strand nicks introduced by a Cas9 nickase (often referred to as a ‘double nick’ or ‘dual nickase’ CRISPR system) are treated as a Double Strand Break (DSB), which can be repaired by either NHEJ or HDR depending on the desired effect on the gene target.
The most commonly used Cas9 is derived from Streptococcus pyogenes and the RuvC domain can be inactivated by a D10A mutation and the HNH domain can be inactivated by an H840A mutation.
In addition to Cas9 derived from S. pyogenes, other RNA guided endonucleases (RGEN) may also be used for programmable genome editing. Cas9 sequences have been identified in more than 600 bacterial strains. Though Cas9 family shows high diversity of amino acid sequences and protein sizes, all Cas9 proteins share a common architecture with a central HNH nuclease domain and a split RuvC/RHase H domain.

Cas12 is a type V CRISPR-CAS system and is also known as Cpf1 or C2c1. It is a compact enzyme from Francisella novicida, Acidaminococcus sp., Lachnospiracaea sp., and Prevotella sp. that is about 1,100 to 1,300 amino acids in length with a guide spacer that is 18-25 nucleotides and a total guide length of 42-44 nucleotides. Cas12 creates staggered cuts in dsDNA and creates a 5 nucleotide 5′ overhang when it cuts. Cas12 also processes its own guide RNAs which leads to increased multiplexing ability. Recently it was determined that Cas12a can cut single-stranded DNA once it is activated by a target DNA molecule matching the spacer sequence.
In some embodiments, the VENOM element is Cas12.
In some embodiments, the VENOM element is Cas12a.
In some embodiments, a Cas12a and a CRISPR array can be encoded in a single transcript using a stabilizer tertiary RNA structure as described by Campa et al. (Multiplexed genome engineering by Cas12a and CRISPR arrays encoded on single transcripts, Nature Methods 2019, doi.org/10.1038/s41592-019-0508-6; the contents of which are herein incorporated by reference in their entirety). Using this method, Campa et al. noted that up to 25 individual CRISPR RNAs can be delivered on a single plasmid. As a non-limiting example, the VENOM elements are Cas12a and a CRISPR array. As a non-limiting example, the VENOM element is Cas12a and a CRISPR array encoded in a single transcript using a stabilizer tertiary RNA structure.
Type V CRISPR systems have several differences from Type II systems. For example, Cas12 is a single RNA-guided endonuclease that, in contrast to Type II systems, lacks tracrRNA and thus are processed into mature crRNAs without the requirement of an additional trans-activating tracrRNA. Cas12 also uses a T-rich protospacer-adjacent motif (PAM) such that Cas12-crRNA complexes efficiently cleave target DNA preceded by a short T-rich PAM so Type V systems cleave at a point that is distant from the PAM.
Cas13 is a Type VI CRISPR-Cas system and is also known as C2c2 or CasRx. It is different than most of the other CRISPR systems because Cas13 targets RNA and not DNA. This is beneficial as Cas13 can be used as a therapeutic for influencing gene expression without altering the genome sequence of the subject. Cas13 is from Leptotrichia buccalis, Leptotrichia shahii, Ruminococcus flavefaciens, Bergeyella zoohelcum, Prevotella buccae, and Listeria seeligeri, and is about 900 to 1,300 amino acids in length with a guide spacer length of 22-30 nucleotides and a total guide length of 52-66 nucleotides. Once Cas13 is activated by a ssRNA sequence which is complementary to its crRNA spacer, Cas13 destroys all nearby RNA regardless of the sequence.
In some embodiments, the VENOM element is Cas13. As a non-limiting example, the Cas13 VENOM element may be used in diagnostics in vitro. As another non-limiting example, the Cas13 VENOM element can be used for specific RNA knockdown or RNA sequence editing in mammalian cells.

In some embodiments REPAIR uses guide RNAs comprising spacers. As a non-limiting example, the spacers are 30 nt in length. As another non-limiting example, the spacers are 50nt in length.
In some embodiments, REPAIR comprises a linker between dCas13b and ADAR2dd (E488Q).
In some embodiments, REPAIR comprises the ADAR2dd with the E488Q mutation fused to catalytically inactive PsPCas13b, which may also be referred to herein as dCas13b. In some embodiments, engineered dCas13b-ADARdd fusions naturally deaminates adenosines to inosines, a base that functionally mimics guanosine in the cell, in dsRNA.
In some embodiments, a guide RNA that hybridizes with the target RNA may generate the requisite duplex RNA substrate for editing and recruiting of the dCas13b-ADARdd fusion comprising REPAIR. The guide RNA crRNA component hybridizes to bases surrounding the target adenosine. The mismatch cytidine in the crRNA opposite the target may enhance the RNA editing reaction to promote adenosine deamination to inosine. In some embodiments, REPAIR comprises a mismatched cytidine opposite the target adenosine that may increase deamination frequency.
In some embodiments, REPAIR may be used for RNA editing in mammalian cells.
In some embodiments, REPAIR is localized to the cytoplasm of cells.
In some embodiments, REPAIR directly deaminates target adenosines to inosines without relying on endogenous cellular repair pathways for desired editing outcomes and therefore may be used in post-mitotic cells. As a non-limiting example, the post-mitotic cell is a neuron.
In some embodiments, destabilizing REPAIR ADAR2dd(E488Q)-RNA binding may selectively decrease off-target editing. As a non-limiting example, REPAIR ADAR2dd(E488Q)-RNA binding is destabilized by applying a rational mutagenesis strategy to vary ADAR2dd(E488Q) residues that contact the RNA duplex.
In some embodiments, the REPAIR ADAR2dd(E488Q) is mutated. As a nonlimiting example, ADAR2dd(E488Q) is mutated to generate in ADAR2dd(E488QMT375G).

In some embodiments, REPAIR may be used to transiently or chronically alter the sequence of expressed, risk-modifying G-to-A variants to decrease the chance of entering a disease state for patient. As a non-limiting example, REPAIR may be used to functionally mimic A-to-G alleles of the Interferon Induced With Helicase C Domain 1 (IFIH1) gene to protect against autoimmune disorders, such as but not limited to type I diabetes and systemic lupus erythematosus.
In some embodiments, REPAIR constructs may be modified for packaging into therapeutically relevant viral vectors, such as but not limited to, AAV vectors. As a non-limiting examples constructs may be modified by C terminal truncations of dCas13 fused to ADAR2dd(E488Q). As another non-limiting example, constructs may be modified by N terminal truncations of dCas13 fused to ADAR2dd(E488Q).
The REPAIR method has no strict sequence constraints and can be used to edit full-length transcripts containing mutations. A variant of the REPAIR method may be used when more specificity is needed. REPAIRv2 as described by Cox et al (Science. 2017 Nov. 24; 358(6366): 1019-1027. doi:10.1126/science.aaq0180) is a method that is at least 919 more specific than REPAIR and is more adaptable to viral delivery.
In some embodiments, the REPAIR method uses the mutant ADAR2dd(E488Q/T375G).
Adenine base editors (ABEs) mediate conversion of A to T and G to C in genomic DNA. Gaudelli et al. reported a tRNA adenosine deaminase to operate on DNA when fused to a catalytically impaired CRISPR-Cas9 (Nature. 2017 Nov. 23; 551(7681): 464-471. doi:10.1038/nature24644; the contents of which are herein incorporated by reference). ABEs are able to introduce point mutations more efficiently and cleanly than the Cas9 nuclease-based method, induce less off-target genome modification than Cas9, and install disease-correcting or disease-suppressing mutations in cells. Additionally, ABEs are able to introduce mutations without double-stranded cleavage.
In some embodiments, the VENOM element is an ABE and can mediate conversion of A to T and G to C in genomic DNA.
Base editor 3 (BE3) converts C to G base pairs or T to A base pairs in a variety of cell lines and with a higher efficiency and lower indel frequency than what can be achieved using other genome editing methods (Komor A. et al. Programmable editing of a target base in genomic DNA without double-stranded DNA cleavage. Nature. 2016; 533:420-424 and Komor et al., Sci. Adv. 2017; 3: eaao4774: the contents of which are herein incorporated by reference in their entireties). In order to operate efficiently, BE3 requires the presence of an NGG PAM that places the target C within a five-nucleotide window near the PAM-distal end of the protospacer, but this limits the number of sites in the human genome that can be efficiently targeted by BE3. In order to expand the number of sites that could be targeted, Kim et al. replaced the nickase form of SpCas9 with that of SaCas9 in BE3 to generate APEBEC1-SaCas9n-UG1 (SaBE3) which can mediate base editing at sites not accessible to BE3 (Nat Biotechnol. 2017 April; 35(4): 371-376. doi:10.1038/nbt.3803; the contents of which are herein incorporated by reference in their entireties).

(Nature Communications, 8:15790, DOI: 10.1038/ncomms15790; the contents of which are incorporated by reference in their entirety).
In some embodiments, nucleobase editing may be used to introduce a stop codon into a gene. The introduction of the stop codon may be used to stop the expression of toxic repeats in a subject.

Most gene editing methods require two homology arms for gene editing. However, Suzuki et al. have recently described precise in vivo gene editing via a single homology arm and intron-targeting gene integration (Cell Research (2019) 0:1-16; doi.org/10.1038/s41422-019-0213-0; the contents of which are herein incorporated by reference in their entireties). The single homology arm provides reduces the amount of homology needed for the gene editing machine to attach to the target gene but it does not address the common issue that incorrect mutations (including deletions) can occur during the cutting and insertion of the new sequence. To address this aspect, Suzuki et al. have discovered that if you target the intron for gene integration, the effect of these undesired mutations is minimized since the intron is not translated. This method is called Single homology Arm donor mediated intron-Targeting Integration (SATI) and allows for the targeting of a broad range of mutations and cell types
In some embodiments, the VENOM element is SATI.
In some embodiments, the SATI method may be used to correct a gene mutation which causes a disease, disorder and/or condition.
A number of switches that function to regulate transgene expression in the context of cell systems and animal models have been described. One such mechanism of regulation relies on a chemical agent, such as a drug, or a physiological stimulus that acts as a switch to turn the expression of a transgene on or off. The most extensively studied regulatory switch mechanism is the Tet ON/OFF system, in which a tet repressor protein can only activate transcription from a promoter with a tet response element in the presence or absence of teracyclin, first described by Bujard and Gossen (Proc Natl Acad Sci USA. 1992 Jun. 15; 89(12):5547-51, Tight control of gene expression in mammalian cells by tetracycline-responsive promoters; the contents of which are herein incorporated by reference in its entirety). Several ligand and hormone regulatable systems, which employ the dimerization of two separate proteins for activation or repression, have also been described.
Approaches in which a second transgene encodes a regulatory enzyme such as a CRE recombinase, which modulates expression of a target transgene through site specific recombination, is extensively used in transgenic mouse studies, where a tissue restricted or temporally restricted expression pattern is desired.
In addition, transgene expression can also be controlled through regulation of transcript mRNA stability or protein stability, through the inclusion of stabilizing or destabilizing elements.
Adeno-associated viruses (AAV) are small non-enveloped icosahedral capsid viruses of the Parvoviridae family characterized by a single stranded DNA vector genome. Parvoviridae family viruses consist of two subfamilies: Parvovirinae, which infect vertebrates, and Densovirinae, which infect invertebrates. The Parvoviridae family comprises the Dependovirus genus which includes AAV, capable of replication in vertebrate hosts including, but not limited to, human, primate, bovine, canine, equine, and ovine species.
The parvoviruses and other members of the Parvoviridae family are generally described in Kenneth 1. Berns, “Parvoviridae: The Viruses and Their Replication,” Chapter 69 in FIELDS VIROLOGY (3d Ed. 1996), the contents of which are incorporated by reference in their entirety.
AAV have proven to be useful as a biological tool due to their relatively simple structure, their ability to infect a wide range of cells (including quiescent and dividing cells) without integration into the host genome and without replicating, and their relatively benign immunogenic profile. The genome of the virus may be manipulated to contain a minimum of components for the assembly of a functional recombinant virus, or viral particle, which is loaded with or engineered to target a particular tissue and express or deliver a desired payload.
The wild-type vector genome is a linear, single-stranded DNA (ssDNA) molecule approximately 5,000 nucleotides (nt) in length. Inverted terminal repeats (ITRs) traditionally cap the vector genome at both the 5′ and the 3′ end, providing origins of replication for the vector genome. While not wishing to be bound by theory, an AAV vector genome typically comprises two ITR sequences. These ITRs have a characteristic T-shaped hairpin structure defined by a self-complementary region (145nt in wild-type AAV) at the 5′ and 3′ ends of the ssDNA which form an energetically stable double stranded region. The double stranded hairpin structures comprise multiple functions including, but not limited to, acting as an origin for DNA replication by functioning as primers for the endogenous DNA polymerase complex of the host viral replication cell.
The wild-type AAV vector genome further comprises nucleotide sequences for two open reading frames, one for the four non-structural Rep proteins (Rep78, Rep68, Rep52. Rep40, encoded by Rep genes) and one for the three capsid, or structural, proteins (VP1, VP2, VP3, encoded by capsid genes or Cap genes). The Rep proteins are important for replication and packaging, while the capsid proteins are assembled to create the protein shell of the AAV, or AAV capsid. Alternative splicing and alternate initiation codons and promoters result in the generation of four different Rep proteins from a single open reading frame and the generation of three capsid proteins from a single open reading frame. Though it varies by AAV serotype, as a non-limiting example, for AAV9/hu.14 (SEQ ID NO: 123 of U.S. Pat. No. 7,906,111, the contents of which are herein incorporated by reference in their entirety) VP1 refers to amino acids 1-736, VP2 refers to amino acids 138-736, and VP3 refers to amino acids 203-736. In other words, VP1 is the full-length capsid sequence, while VP2 and VP3 are shorter components of the whole. As a result, changes in the sequence in the VP3 region, are also changes to VP1 and VP2, however, the percent difference as compared to the parent sequence will be greatest for VP3 since it is the shortest sequence of the three. Though described here in relation to the amino acid sequence, the nucleic acid sequence encoding these proteins can be similarly described. Together, the three capsid proteins assemble to create the AAV capsid protein. While not wishing to be bound by theory, the AAV capsid protein typically comprises a molar ratio of 1:1:10 of VP1:VP2:VP3. As used herein, an “AAV serotype” is defined primarily by the AAV capsid. In some instances, the ITRs are also specifically described by the AAV serotype (e.g., AAV2/9).
For use as a biological tool, the wild-type AAV vector genome can be modified to replace the rep/cap sequences with a nucleic acid sequence comprising a payload region with at least one ITR region. Typically, in recombinant AAV vector genomes there are two ITR regions. The rep/cap sequences can be provided in trans during production to generate AAV particles and/or VAPs.
In addition to the encoded heterologous payload, vector genomes may comprise the vector genome, in whole or in part, of any naturally occurring and/or recombinant AAV serotype nucleotide sequence or variant. AAV variants may have sequences of significant homology at the nucleic acid (genome or capsid) and amino acid levels (capsids), to produce constructs which are generally physical and functional equivalents, replicate by similar mechanisms, and assemble by similar mechanisms.

Vir. 74: 8635-47 (2000), the contents of each of which are incorporated herein by reference in their entirety.
In some embodiments, AAV particles and/or VAPs of the present disclosure are recombinant AAV viral vectors which are replication defective and lacking sequences encoding functional Rep and Cap proteins within their vector genome. These defective vector genomes may lack most or all parental coding sequences and essentially carry only one or two AAV ITR sequences and the nucleic acid of interest for delivery to a cell, a tissue, an organ, or an organism.
In some embodiments, the vector genome of the AAV particles and/or VAPs of the present disclosure comprise at least one control element which provides for the replication, transcription, and translation of a coding sequence encoded therein. Not all of the control elements need always be present as long as the coding sequence is capable of being replicated, transcribed, and/or translated in an appropriate host cell. Non-limiting examples of expression control elements include sequences for transcription initiation and/or termination, promoter and/or enhancer sequences, efficient RNA processing signals such as splicing and polyadenylation signals, sequences that stabilize cytoplasmic mRNA, sequences that enhance translation efficacy (e.g., Kozak consensus sequence), sequences that enhance protein stability, and/or sequences that enhance protein processing and/or secretion.
According to the present disclosure, AAV particles and/or VAPs for use in therapeutics and/or diagnostics comprise a virus that has been distilled or reduced to the minimum components necessary for transduction of a nucleic acid payload or cargo of interest. In this manner, AAV particles and/or VAPs are engineered as vehicles for specific delivery while lacking the deleterious replication and/or integration features found in wild-type viruses.
In addition to single stranded AAV vector genomes (e.g., ssAAVs), the present disclosure also provides for self-complementary AAV (scAAVs) vector genomes, scAAV vector genomes contain DNA strands which anneal together to form double stranded DNA. By skipping second strand synthesis, scAAVs allow for rapid expression in the transduced cell.
In some embodiments, the AAV particle and/or VAP of the present disclosure is an scAAV.
In some embodiments, the AAV particle and/or VAP of the present disclosure is an ssAAV.

AAV particles and/or VAPs may be modified to enhance the efficiency of delivery. Such modified AAV particles and/or VAPs can be packaged efficiently and be used to successfully infect the target cells at high frequency and with minimal toxicity. In some embodiments, the capsids of the AAV particles and/or VAPs are engineered according to the methods described in US Publication Number US20130195801, the contents of which are incorporated herein by reference in their entirety.
In some embodiments, the AAV particles and/or VAPs comprising a payload region encoding the polypeptides may be introduced into mammalian cells.

The present disclosure refers to structural capsid proteins (including VP1, VP2 and VP3) which are encoded by capsid (Cap) genes. These capsid proteins form an outer protein structural shell (i.e. capsid) of a viral vector such as AAV. VP capsid proteins synthesized from Cap polynucleotides generally include a methionine as the first amino acid in the peptide sequence (Met1), which is associated with the start codon (AUG or ATG) in the corresponding Cap nucleotide sequence. However, it is common for a first-methionine (Met1) residue or generally any first amino acid (AA1) to be cleaved off after or during polypeptide synthesis by protein processing enzymes such as Met-aminopeptidases. This “Met/AA-clipping” process often correlates with a corresponding acetylation of the second amino acid in the polypeptide sequence (e.g., alanine, valine, serine, threonine, etc.). Met-clipping commonly occurs with VP1 and VP3 capsid proteins but can also occur with VP2 capsid proteins.
Where the Met/AA-clipping is incomplete, a mixture of one or more (one, two or three) VP capsid proteins comprising the viral capsid may be produced, some of which may include a Met1/AA1 amino acid (Met+/AA+) and some of which may lack a Met1/AA1 amino acid as a result of Met/AA-clipping (Met−/AA−). For further discussion regarding Met/AA-clipping in capsid proteins, see Jin, et al. Direct Liquid Chromatography/Mass Spectrometry Analysis for Complete Characterization of Recombinant Adeno-Associated Virus Capsid Proteins. Hum Gene Ther Methods. 2017 Oct. 28(5):255-267; Hwang, et al. N-Terminal Acetylation of Cellular Proteins Creates Specific Degradation Signals. Science. 2010 Feb. 19, 327(5968): 973-977; the contents of which are each incorporated herein by reference in its entirety.
According to the present disclosure, references to capsid proteins is not limited to either clipped (Met−/AA−) or unclipped (Met+/AA+) and may, in context, refer to independent capsid proteins, viral capsids comprised of a mixture of capsid proteins, and/or polynucleotide sequences (or fragments thereof) which encode, describe, produce or result in capsid proteins of the present disclosure. A direct reference to a “capsid protein” or “capsid polypeptide” (such as VP1, VP2 or VP2) may also comprise VP capsid proteins which include a Met1/AA1 amino acid (Met+/AA+) as well as corresponding VP capsid proteins which lack the Met1/AA1 amino acid as a result of Met/AA-clipping (Met−/AA−).
Further according to the present disclosure, a reference to a specific SEQ ID NO: (whether a protein or nucleic acid) which comprises or encodes, respectively, one or more capsid proteins which include a Met1/AA1 amino acid (Met+/AA+) should be understood to teach the VP capsid proteins which lack the Met1/AA1 amino acid as upon review of the sequence, it is readily apparent any sequence which merely lacks the first listed amino acid (whether or not Met1/AA1).
As a non-limiting example, reference to a VP1 polypeptide sequence which is 736 amino acids in length and which includes a “Met1” amino acid (Met+) encoded by the AUG/ATG start codon may also be understood to teach a VP1 polypeptide sequence which is 735 amino acids in length and which does not include the “Met1” amino acid (Met−) of the 736 amino acid Met+ sequence. As a second non-limiting example, reference to a VP1 polypeptide sequence which is 736 amino acids in length and which includes an “AA1” amino acid (AA1+) encoded by any NNN initiator codon may also be understood to teach a VP1 polypeptide sequence which is 735 amino acids in length and which does not include the “AA1” amino acid (AA1−) of the 736 amino acid AA1+ sequence.
References to viral capsids formed from VP capsid proteins (such as reference to specific AAV capsid serotypes), can incorporate VP capsid proteins which include a Met1/AA1 amino acid (Met+/AA1+), corresponding VP capsid proteins which lack the Met1/AA1 amino acid as a result of Met/AA1-clipping (Met−/AA1−), and combinations thereof (Met+/AA1+ and Met−/AA1−).
As a non-limiting example, an AAV capsid serotype can include VP1 (Met+/AA1+), VP1 (Met−/AA1−), or a combination of VP1 (Met+/AA1+) and VP1 (Met−/AA1−). An AAV capsid serotype can also include VP3 (Met+/AA1+), VP3 (Met−/AA1−), or a combination of VP3 (Met+/AA1+) and VP3 (Met−/AA1−): and can also include similar optional combinations of VP2 (Met+/AA1) and VP2 (Met−/AA1−).
Vector genome Component: Inverted Terminal Repeats (ITRs)
The AAV particles and/or VAPs of the present disclosure comprise a vector genome with at least one ITR region and a payload region. In some embodiments, the vector genome has two ITRs. These two ITRs flank the payload region at the 5′ and 3′ ends. The ITRs function as origins of replication comprising recognition sites for replication. ITRs comprise sequence regions which can be complementary and symmetrically arranged. ITRs incorporated into vector genomes may be comprised of naturally occurring polynucleotide sequences or recombinantly derived polynucleotide sequences.
The ITRs may be derived from the same serotype as the capsid, selected from any of the serotypes listed in Table 1, or a derivative thereof. The ITR may be of a different serotype than the capsid. In some embodiments, the AAV particle and/or VAP has more than one ITR. In a non-limiting example, the AAV particle and/or VAP has a vector genome comprising two ITRs. In some embodiments, the ITRs are of the same serotype as one another. In another embodiment, the ITRs are of different serotypes. Non-limiting examples include zero, one or both of the ITRs having the same serotype as the capsid. In some embodiments both ITRs of the vector genome of the AAV particle and/or VAP are AAV2 ITRs.

Non-limiting examples of elements to enhance the transgene target specificity and expression include promoters, endogenous miRNAs, post-transcriptional regulatory elements (PREs), polyadenylation (PolyA) signal sequences and upstream enhancers (USEs), CMV enhancers and introns.
A person skilled in the art may recognize that expression of the polypeptides in a target cell may require a specific promoter, including but not limited to, a promoter that is species specific, inducible, tissue-specific, or cell cycle-specific (Parr et al., Nat. Med. 3: 1145-9 (1997); the contents of which are herein incorporated by reference in their entirety).

Yu et al. (Molecular Pain 2011, 7:63; the contents of which are herein incorporated by reference in their entirety) evaluated the expression of eGFP under the CAG, EF1α, PGK and UBC promoters in rat DRG cells and primary DRG cells using lentiviral vectors and found that UBC showed weaker expression than the other 3 promoters and only 10-12% glial expression was seen for all promoters. Soderblom et al. (E. Neuro 2015; the contents of which are herein incorporated by reference in its entirety) evaluated the expression of eGFP in AAV8 with CMV and UBC promoters and AAV2 with the CMV promoter after injection in the motor cortex. Intranasal administration of a plasmid containing a UBC or EF1α promoter showed a sustained airway expression greater than the expression with the CMV promoter (See e.g., Gill et al., Gene Therapy 2001, Vol. 8, 1539-1546; the contents of which are herein incorporated by reference in their entirety). Husain et al. (Gene Therapy 2009; the contents of which are herein incorporated by reference in its entirety) evaluated an HβH construct with a hGUSB promoter, an HSV-1LAT promoter and an NSE promoter and found that the HβH construct showed weaker expression than NSE in mouse brain. Passini and Wolfe (J. Virol. 2001, 12382-12392, the contents of which are herein incorporated by reference in its entirety) evaluated the long-term effects of the HβH vector following an intraventricular injection in neonatal mice and found that there was sustained expression for at least 1 year. Low expression in all brain regions was found by Xu et al. (Gene Therapy 2001, 8, 1323-1332; the contents of which are herein incorporated by reference in their entirety) when NFL and NFH promoters were used as compared to the CMV-lacZ, CMV-luc, EF, GFAP, hENK, nAChR, PPE, PPE+wpre, NSE (0.3 kb), NSE (1.8 kb) and NSE (1.8 kb+wpre). Xu et al. found that the promoter activity in descending order was NSE (1.8 kb), EF, NSE (0.3 kb), GFAP, CMV, hENK, PPE, NFL and NFH. NFL is a 650 nucleotide promoter and NFH is a 920-nucleotide promoter which are both absent in the liver but NFH is abundant in the sensory proprioceptive neurons, brain and spinal cord and NFH is present in the heart. Scn8a is a 470 nucleotide promoter which expresses throughout the DRG, spinal cord and brain with particularly high expression seen in the hippocampal neurons and cerebellar Purkinje cells, cortex, thalamus, and hypothalamus (See e.g., Drews et al.

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

Vector genomes may be engineered with one or more spacer or linker regions to separate coding or non-coding regions.
In some embodiments, the payload region of the AAV particle and/or VAP may optionally encode one or more linker sequences. In some cases, the linker may be a peptide linker that may be used to connect the polypeptides encoded by the payload region. Some peptide linkers may be cleaved after expression to separate the polypeptides. Linker cleavage may be enzymatic. In some cases, linkers comprise an enzymatic cleavage site to facilitate intracellular or extracellular cleavage. Some payload regions encode linkers that interrupt polypeptide synthesis during translation of the linker sequence from an mRNA transcript. Such linkers may facilitate the translation of separate protein domains from a single transcript. In some cases, two or more linkers are encoded by a payload region of the vector genome. Non-limiting examples of linkers that may be encoded by the payload region of an AAV particle and/or VAP vector genome are given in Table 2.
Some payload regions encode linkers comprising furin cleavage sites. Furin is a calcium dependent serine endoprotease that cleaves proteins just downstream of a basic amino acid target sequence (Arg-X-(Arg/Lys)-Arg) (Thomas, G., 2002. Nature Reviews Molecular Cell Biology 3(10): 753-66; the contents of which are herein incorporated by reference in its entirety). Furin is enriched in the trans-golgi network where it is involved in processing cellular precursor proteins. Furin also plays a role in activating a number of pathogens. This activity can be taken advantage of for expression of polypeptides.
2A peptides are small “self-cleaving” peptides (18-22 amino acids) derived from viruses such as foot-and-mouth disease virus (F2A), porcine teschovirus-1 (P2A). Thoseaasigna virus (T2A), or equine rhinitis A virus (E2A). The 2A designation refers specifically to a region of picornavirus polyproteins that lead to a ribosomal skip at the glycyl-prolyl bond in the C-terminus of the 2A peptide (Kim, J. H. et al., 2011. PLoS One 6(4): e18556; the contents of which are herein incorporated by reference in its entirety). This skip results in a cleavage between the 2A peptide and its immediate downstream peptide. As opposed to IRES linkers, 2A peptides generate stoichiometric expression of proteins flanking the 2A peptide and their shorter length can be advantageous in generating viral expression vectors.
Internal ribosomal entry site (IRES) is a nucleotide sequence (>500 nucleotides) that allows for initiation of translation in the middle of an mRNA sequence (Kim, J. H. et al., 2011. PLoS One 6(4): e18556; the contents of which are herein incorporated by reference in its entirety). Use of an IRES sequence ensures co-expression of genes before and after the IRES, though the sequence following the IRES may be transcribed and translated at lower levels than the sequence preceding the IRES sequence.
In some embodiments, the payload region may encode one or more linkers comprising cathepsin, matrix metalloproteinases or legumain cleavage sites. Such linkers are described e.g. by Cizeau and Macdonald in International Publication No. WO2008052322, the contents of which are herein incorporated in their entirety. Cathepsins are a family of proteases with unique mechanisms to cleave specific proteins. Cathepsin B is a cysteine protease and cathepsin D is an aspartyl protease. Matrix metalloproteinases are a family of calcium-dependent and zinc-containing endopeptidases. Legumain is an enzyme catalyzing the hydrolysis of (-Asn-Xaa-) bonds of proteins and small molecule substrates.
In some embodiments, payload regions may encode linkers that are not cleaved. Such linkers may include a simple amino acid sequence, such as a glycine rich sequence. In some cases, linkers may comprise flexible peptide linkers comprising glycine and serine residues. The linker may comprise flexible peptide linkers of different lengths, e.g. n×G4S, where n=1-10 (SEQ ID NO: 1743), and the length of the encoded linker varies between 5 and 50 amino acids. In a non-limiting example, the linker may be 5×G4S (SEQ ID NO: 1742). These flexible linkers are small and without side chains, so they tend not to influence secondary protein structure while providing a flexible linker between antibody segments (George, R. A., et al., 2002. Protein Engineering 15(11): 871-9; Huston. J. S. et al., 1988. PNAS 85:5879-83; and Shan, D. et al., 1999. Journal of Immunology. 162(11):6589-95; the contents of each of which are herein incorporated by reference in their entirety). Furthermore, the polarity of the serine residues improves solubility and prevents aggregation problems.
In some embodiments, payload regions may encode small and unbranched serine-rich peptide linkers, such as those described by Huston et al. in U.S. Pat. No. 5,525,491, the contents of which are herein incorporated in their entirety. Polypeptides encoded by the payload region, linked by serine-rich linkers, have increased solubility.
In some embodiments, payload regions may encode artificial linkers, such as those described by Whitlow and Filpula in U.S. Pat. No. 5,856,456 and Ladner et al. in U.S. Pat. No. 4,946,778, the contents of each of which are herein incorporated by their entirety.
In some embodiments, the payload region encodes at least one G4S3 linker (“G4S3” disclosed as SEQ ID NO: 1741).
In some embodiments, the payload region encodes at least one G4S linker (“G4S” disclosed as SEQ ID NO: 1740).
In some embodiments, the payload region encodes at least one furin site.
In some embodiments, the payload region encodes at least one T2A linker.
In some embodiments, the payload region encodes at least one F2A linker.
In some embodiments, the payload region encodes at least one P2A linker.
In some embodiments, the payload region encodes at least one IRES sequence.
In some embodiments, the payload region encodes at least one G4S5 linker (“G4S5” disclosed as SEQ ID NO: 1742).
In some embodiments, the payload region encodes at least one furin and one 2A linker.
In some embodiments, the payload region encodes at least one hinge region. As a non-limiting example, the hinge is an IgG hinge.
In some embodiments, the linker region may be 1-50, 1-100, 50-100, 50-150, 100-150, 100-200, 150-200, 150-250, 200-250, 200-300, 250-300, 250-350, 300-350, 300-400, 350-400, 350-450, 400-450, 400-500, 450-500, 450-550, 500-550, 500-600, 550-600, 550-650, or 600-650 nucleotides in length. The linker region may have a length of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 115, 120, 125, 130, 135, 140, 145, 150, 151, 152, 153, 154, 155, 156, 157, 158, 159, 160, 165, 170, 171, 172, 173, 174, 175, 176, 177, 178, 179, 180, 185, 190, 191, 192, 193, 194, 195, 196, 197, 198, 199, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, 300, 310, 320, 330, 340, 350, 360, 370, 380, 390, 400, 410, 420, 430, 440, 450, 460, 470, 480, 490, 500, 510, 520, 530, 540, 550, 560, 570, 580, 590, 600, 601, 602, 603, 604, 605, 606, 607, 608, 609, 610, 611, 612, 613, 614, 615, 616, 617, 618, 619, 620, 621, 622, 623, 624, 625, 626, 627, 628, 629, 630, 631, 632, 633, 634, 635, 640, 650 or greater than 650.

Codon-optimization may be achieved by any method known to one with skill in the art such as, but not limited to, by a method according to Genescript, EMBOSS, Bioinformatics, NUS, NUS2, Geneinfinity, IDT, NUS3, GregThatcher, Insilico, Molbio, N2P, Snapgene, and/or VectorNTI. Antibody heavy and/or light chain sequences within the same vector genome may be codon-optimized according to the same or according to different methods.
VENOM elements by payload regions of the vector genomes may be translated as a whole polypeptide, a plurality of polypeptides or fragments of polypeptides, which independently may be encoded by one or more nucleic acids, fragments of nucleic acids or variants of any of the aforementioned. As used herein, “polypeptide” means a polymer of amino acid residues (natural or unnatural) linked together most often by peptide bonds. The term, as used herein, refers to proteins, polypeptides, and peptides of any size, structure, or function. In some instances, the polypeptide encoded is smaller than about 50 amino acids and the polypeptide is then termed a peptide. If the polypeptide is a peptide, it will be at least about 2, 3, 4, or at least 5 amino acid residues long. Thus, polypeptides include gene products, naturally occurring polypeptides, synthetic polypeptides, homologs, orthologs, paralogs, fragments and other equivalents, variants, and analogs of the foregoing. A polypeptide may be a single molecule or may be a multi-molecular complex such as a dimer, trimer or tetramer. They may also comprise single chain or multichain polypeptides and may be associated or linked. The term polypeptide may also apply to amino acid polymers in which one or more amino acid residues are an artificial chemical analogue of a corresponding naturally occurring amino acid.
The term “polypeptide variant” refers to molecules which differ in their amino acid sequence from a native or reference sequence. The amino acid sequence variants may possess substitutions, deletions, and/or insertions at certain positions within the amino acid sequence, as compared to a native or reference sequence. Ordinarily, variants will possess at least about 50% identity (homology) to a native or reference sequence, and preferably, they will be at least about 80%, more preferably at least about 90% identical (homologous) to a native or reference sequence.
In some embodiments “variant mimics” are provided. As used herein, the term “variant mimic” is one which contains one or more amino acids which would mimic an activated sequence. For example, glutamate may serve as a mimic for phosphoro-threonine and/or phosphoro-serine. Alternatively, variant mimics may result in deactivation or in an inactivated product containing the mimic, e.g., phenylalanine may act as an inactivating substitution for tyrosine; or alanine may act as an inactivating substitution for serine.
The term “amino acid sequence variant” refers to molecules with some differences in their amino acid sequences as compared to a native or starting sequence. The amino acid sequence variants may possess substitutions, deletions, and/or insertions at certain positions within the amino acid sequence. “Native” or “starting” sequence should not be confused with a wild type sequence. As used herein, a native or starting sequence is a relative term referring to an original molecule against which a comparison may be made. “Native” or “starting” sequences or molecules may represent the wild-type (that sequence found in nature) but do not have to be the wild-type sequence.
Ordinarily, variants will possess at least about 70% homology to a native sequence, and preferably, they will be at least about 80%, more preferably at least about 90% homologous to a native sequence. “Homology” as it applies to amino acid sequences is defined as the percentage of residues in the candidate amino acid sequence that are identical with the residues in the amino acid sequence of a second sequence after aligning the sequences and introducing gaps, if necessary, to achieve the maximum percent homology. Methods and computer programs for the alignment are well known in the art. It is understood that homology depends on a calculation of percent identity but may differ in value due to gaps and penalties introduced in the calculation.
By “homologs” as it applies to amino acid sequences is meant the corresponding sequence of other species having substantial identity to a second sequence of a second species.
“Analogs” is meant to include polypeptide variants which differ by one or more amino acid alterations, e.g., substitutions, additions, or deletions of amino acid residues that still maintain the properties of the parent polypeptide.
Sequence tags or amino acids, such as one or more lysines, can be added to the peptide sequences (e.g., at the N-terminal or C-terminal ends). Sequence tags can be used for peptide purification or localization. Lysines can be used to increase peptide solubility or to allow for biotinylation. Alternatively, amino acid residues located at the carboxy and amino terminal regions of the amino acid sequence of a peptide or protein may optionally be deleted providing for truncated sequences. Certain amino acids (e.g., C-terminal or N-terminal residues) may alternatively be deleted depending on the use of the sequence, as for example, expression of the sequence as part of a larger sequence which is soluble, or linked to a solid support.
“Substitutional variants” when referring to proteins are those that have at least one amino acid residue in a native or starting sequence removed and a different amino acid inserted in its place at the same position. The substitutions may be single, where only one amino acid in the molecule has been substituted, or they may be multiple, where two or more amino acids have been substituted in the same molecule.
As used herein the term “conservative amino acid substitution” refers to the substitution of an amino acid that is normally present in the sequence with a different amino acid of similar size, charge, or polarity. Examples of conservative substitutions include the substitution of a non-polar (hydrophobic) residue such as isoleucine, valine, and leucine for another non-polar residue. Likewise, examples of conservative substitutions include the substitution of one polar (hydrophilic) residue for another such as between arginine and lysine, between glutamine and asparagine, and between glycine and serine. Additionally, the substitution of a basic residue such as lysine, arginine, or histidine for another, or the substitution of one acidic residue such as aspartic acid or glutamic acid for another acidic residue are additional examples of conservative substitutions. Examples of non-conservative substitutions include the substitution of a non-polar (hydrophobic) amino acid residue such as isoleucine, valine, leucine, alanine, methionine for a polar (hydrophilic) residue such as cysteine, glutamine, glutamic acid or lysine and/or a polar residue for a non-polar residue.
“Insertional variants” when referring to proteins are those with one or more amino acids inserted immediately adjacent to an amino acid at a particular position in a native or starting sequence. “Immediately adjacent” to an amino acid means connected to either the alpha-carboxy or alpha-amino functional group of the amino acid.
“Deletional variants” when referring to proteins, are those with one or more amino acids in the native or starting amino acid sequence removed. Ordinarily, deletional variants will have one or more amino acids deleted in a particular region of the molecule.
As used herein, the term “derivative” is used synonymously with the term “variant” and refers to a molecule that has been modified or changed in any way relative to a reference molecule or starting molecule. In some embodiments, derivatives include native or starting proteins that have been modified with an organic proteinaceous or non-proteinaceous derivatizing agent, and post-translational modifications. Covalent modifications are traditionally introduced by reacting targeted amino acid residues of the protein with an organic derivatizing agent that is capable of reacting with selected side-chains or terminal residues, or by harnessing mechanisms of post-translational modifications that function in selected recombinant host cells. The resultant covalent derivatives are useful in programs directed at identifying residues important for biological activity, for immunoassays, or for the preparation of anti-protein antibodies for immunoaffinity purification of the recombinant glycoprotein. Such modifications are within the ordinary skill in the art and are performed without undue experimentation.
Certain post-translational modifications are the result of the action of recombinant host cells on the expressed polypeptide. Glutaminyl and asparaginyl residues are frequently post-translationally deamidated to the corresponding glutamyl and aspartyl residues. Alternatively, these residues are deamidated under mildly acidic conditions. Either form of these residues may be present in the proteins used in accordance with the present disclosure.
Other post-translational modifications include hydroxylation of proline and lysine, phosphorylation of hydroxyl groups of seryl or threonyl residues, methylation of the alpha-amino groups of lysine, arginine, and histidine side chains (T. E. Creighton, Proteins: Structure and Molecular Properties, W.H. Freeman & Co., San Francisco, pp. 79-86 (1983)).
“Features” when referring to proteins are defined as distinct amino acid sequence-based components of a molecule. Features of the proteins of the present disclosure include surface manifestations, local conformational shape, folds, loops, half-loops, domains, half-domains, sites, termini or any combination thereof.
As used herein when referring to proteins the term “surface manifestation” refers to a polypeptide-based component of a protein appearing on an outermost surface.
As used herein when referring to proteins the term “local conformational shape” means a polypeptide based structural manifestation of a protein which is located within a definable space of the protein.
As used herein when referring to proteins the term “fold” means the resultant conformation of an amino acid sequence upon energy minimization. A fold may occur at the secondary or tertiary level of the folding process. Examples of secondary level folds include beta sheets and alpha helices. Examples of tertiary folds include domains and regions formed due to aggregation or separation of energetic forces. Regions formed in this way include hydrophobic and hydrophilic pockets, and the like.
As used herein the term “turn” as it relates to protein conformation means a bend which alters the direction of the backbone of a peptide or polypeptide and may involve one, two, three or more amino acid residues.
As used herein when referring to proteins the term “loop” refers to a structural feature of a peptide or polypeptide which reverses the direction of the backbone of a peptide or polypeptide and comprises four or more amino acid residues. Oliva et al. have identified at least 5 classes of protein loops (J. Mol Biol 266 (4): 814-830; 1997).
As used herein when referring to proteins the term “half-loop” refers to a portion of an identified loop having at least half the number of amino acid residues as the loop from which it is derived. It is understood that loops may not always contain an even number of amino acid residues. Therefore, in those cases where a loop contains or is identified to comprise an odd number of amino acids, a half-loop of the odd-numbered loop will comprise the whole number portion or next whole number portion of the loop (number of amino acids of the loop/2+/−0.5 amino acids). For example, a loop identified as a 7-amino acid loop could produce half-loops of 3 amino acids or 4 amino acids (7/2=3.5+/−0.5 being 3 or 4).
As used herein when referring to proteins the term “domain” refers to a motif of a polypeptide having one or more identifiable structural or functional characteristics or properties (e.g., binding capacity, serving as a site for protein-protein interactions).
As used herein when referring to proteins the term “half-domain” means portion of an identified domain having at least half the number of amino acid residues as the domain from which it is derived. It is understood that domains may not always contain an even number of amino acid residues. Therefore, in those cases where a domain contains or is identified to comprise an odd number of amino acids, a half-domain of the odd-numbered domain will comprise the whole number portion or next whole number portion of the domain (number of amino acids of the domain/2+/−0.5 amino acids). For example, a domain identified as a 7-amino acid domain could produce half-domains of 3 amino acids or 4 amino acids (7/2=3.5+/−0.5 being 3 or 4). It is also understood that sub-domains may be identified within domains or half-domains, these subdomains possessing less than all of the structural or functional properties identified in the domains or half domains from which they were derived. It is also understood that the amino acids that comprise any of the domain types herein need not be contiguous along the backbone of the polypeptide (i.e., nonadjacent amino acids may fold structurally to produce a domain, half-domain or subdomain).
As used herein when referring to proteins the terms “site” as it pertains to amino acid-based embodiments is used synonymous with “amino acid residue” and “amino acid side chain”. A site represents a position within a peptide or polypeptide that may be modified, manipulated, altered, derivatized or varied within the polypeptide-based molecules of the present disclosure.
As used herein the terms “termini or terminus” when referring to proteins refers to an extremity of a peptide or polypeptide. Such extremity is not limited only to the first or final site of the peptide or polypeptide but may include additional amino acids in the terminal regions. The polypeptide-based molecules of the present disclosure may be characterized as having both an N-terminus (terminated by an amino acid with a free amino group (NH2)) and a C-terminus (terminated by an amino acid with a free carboxyl group (COOH)). Proteins are in some cases made up of multiple polypeptide chains brought together by disulfide bonds or by non-covalent forces (multimers, oligomers). These sorts of proteins will have multiple N- and C-termini. Alternatively, the termini of the polypeptides may be modified such that they begin or end, as the case may be, with a non-polypeptide-based moiety such as an organic conjugate.
Once any of the features have been identified or defined as a component of a molecule, any of several manipulations and/or modifications of these features may be performed by moving, swapping, inverting, deleting, randomizing, or duplicating. Furthermore, it is understood that manipulation of features may result in the same outcome as a modification to the molecules. For example, a manipulation which involves deleting a domain would result in the alteration of the length of a molecule just as modification of a nucleic acid to encode less than a full-length molecule would.
Modifications and manipulations can be accomplished by methods known in the art such as site directed mutagenesis. The resulting modified molecules may then be tested for activity using in vitro or in vivo assays such as those described herein, or any other suitable screening assay known in the art.

Administered in combination: As used herein, the term “administered in combination” or “combined administration” means that two or more agents are administered to a subject at the same time or within an interval such that there may be an overlap of an effect of each agent on the patient. In some embodiments, they are administered within about 60, 30, 15, 10, 5, or 1 minute of one another. In some embodiments, the administrations of the agents are spaced sufficiently closely together such that a combinatorial (e.g., a synergistic) effect is achieved.
Amelioration: As used herein, the term “amelioration” or “ameliorating” refers to a lessening of severity of at least one indicator of a condition or disease. For example, in the context of neurodegeneration disorder, amelioration includes the reduction of neuron loss.
Animal: As used herein, the term “animal” refers to any member of the animal kingdom. In some embodiments, “animal” refers to humans at any stage of development. In some embodiments, “animal” refers to non-human animals at any stage of development. In certain embodiments, the non-human animal is a mammal (e.g., a rodent, a mouse, a rat, a rabbit, a monkey, a dog, a cat, a sheep, cattle, a primate, or a pig).

In certain embodiments, the term “approximately” or “about” refers to a range of values that fall within 25%, 20%, 19%, 18%, 17%, 16%, 15%, 14%, 13%, 12%, 11%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, or less in either direction (greater than or less than) of the stated reference value unless otherwise stated or otherwise evident from the context (except where such number would exceed 100% of a possible value).
Associated with: As used herein, the terms “associated with,” “conjugated,” “linked,” “attached,” and “tethered,” when used with respect to two or more moieties, means that the moieties are physically associated or connected with one another, either directly or via one or more additional moieties that serves as a linking agent, to form a structure that is sufficiently stable so that the moieties remain physically associated under the conditions in which the structure is used, e.g., physiological conditions. An “association” need not be strictly through direct covalent chemical bonding. It may also suggest ionic or hydrogen bonding or a hybridization-based connectivity sufficiently stable such that the “associated” entities remain physically associated.
Bifunctional: As used herein, the term “bifunctional” refers to any substance, molecule or moiety which is capable of or maintains at least two functions. The functions may affect the same outcome or a different outcome. The structure that produces the function may be the same or different.
Biocompatible: As used herein, the term “biocompatible” means compatible with living cells, tissues, organs or systems posing little to no risk of injury, toxicity or rejection by the immune system.
Biodegradable: As used herein, the term “biodegradable” means capable of being broken down into innocuous products by the action of living things.
Biologically active: As used herein, the phrase “biologically active” refers to a characteristic of any substance that has activity in a biological system and/or organism. For instance, a substance that, when administered to an organism, has a biological effect on that organism, is considered to be biologically active. In particular embodiments, an AAV particle of the present disclosure may be considered biologically active if even a portion of the encoded payload is biologically active or mimics an activity considered biologically relevant.
Capsid: As used herein, the term “capsid” refers to the protein shell of a virus particle.
Chimeric antigen receptor (CAR): As used herein, the term “chimeric antigen receptor” or “CAR” refers to an artificial chimeric protein comprising at least one antigen specific targeting region (ASTR), a transmembrane domain and an intracellular signaling domain, wherein the antigen specific targeting region comprises a full-length antibody or a fragment thereof. Any molecule that is capable of binding a target antigen with high affinity can be used in the ASTR of a CAR. The CAR may optionally have an extracellular spacer domain and/or a co-stimulatory domain. A CAR may also be used to generate a cytotoxic cell carrying the CAR.
Complementary and substantially complementary: As used herein, the term “complementary” refers to the ability of polynucleotides to form base pairs with one another. Base pairs are typically formed by hydrogen bonds between nucleotide units in antiparallel polynucleotide strands. Complementary polynucleotide strands can form base pair in the Watson-Crick manner (e.g., A to T, A to U, C to G), or in any other manner that allows for the formation of duplexes. As persons skilled in the art are aware, when using RNA as opposed to DNA, uracil rather than thymine is the base that is considered to be complementary to adenosine. However, when a U is denoted in the context of the present disclosure, the ability to substitute a T is implied, unless otherwise stated. Perfect complementarity or 100% complementarity refers to the situation in which each nucleotide unit of one polynucleotide strand can form hydrogen bond with a nucleotide unit of a second polynucleotide strand. Less than perfect complementarity refers to the situation in which some, but not all, nucleotide units of two strands can form hydrogen bond with each other. For example, for two 20-mers, if only two base pairs on each strand can form hydrogen bond with each other, the polynucleotide strands exhibit 10% complementarity. In the same example, if 18 base pairs on each strand can form hydrogen bonds with each other, the polynucleotide strands exhibit 90% complementarity. As used herein, the term “substantially complementary” means that the siRNA has a sequence (e.g., in the antisense strand) which is sufficient to bind the desired target mRNA, and to trigger the RNA silencing of the target mRNA.
Compound: Compounds of the present disclosure include all of the isotopes of the atoms occurring in the intermediate or final compounds. “Isotopes” refers to atoms having the same atomic number but different mass numbers resulting from a different number of neutrons in the nuclei. For example, isotopes of hydrogen include tritium and deuterium.
The compounds and salts of the present disclosure can be prepared in combination with solvent or water molecules to form solvates and hydrates by routine methods.
Conditionally active: As used herein, the term “conditionally active” refers to a mutant or variant of a wild-type polypeptide, wherein the mutant or variant is more or less active at physiological conditions than the parent polypeptide. Further, the conditionally active polypeptide may have increased or decreased activity at aberrant conditions as compared to the parent polypeptide. A conditionally active polypeptide may be reversibly or irreversibly inactivated at normal physiological conditions or aberrant conditions.

Methods of measuring the amount or levels of RNA, mRNA, polypeptides and peptides are well known in the art.
Homology: As used herein, the term “homology” refers to the overall relatedness between polymeric molecules, e.g. between polynucleotide molecules (e.g. DNA molecules and/or RNA molecules) and/or between polypeptide molecules.

In some embodiments, homologous polynucleotide sequences are characterized by the ability to encode a stretch of at least 4-5 uniquely specified amino acids. For polynucleotide sequences less than 60 nucleotides in length, homology is determined by the ability to encode a stretch of at least 4-5 uniquely specified amino acids.

Homology directed repair (HL)R): As used herein, the term “homology directed repair” refers to a mechanism in cells to repair DNA double-strand break using a homologous template. HDR generally requires a DNA donor template for requisite sequence homology with the sequence flanking the double-strand break so that the DNA donor can serve as a suitable template for repair. In some embodiments, HDR results in the replacement of the entire DNA donor or a portion of the DNA donor sequence at the site of the DNA target sequence.
Homologous Region: As used herein the term “homologous region” refers to a region which is similar in position, structure, evolution origin, character, form or function.
Identity: As used herein, the term “identity” refers to the overall relatedness between polymeric molecules, e.g., between polynucleotide molecules (e.g. DNA molecules and/or RNA molecules) and/or between polypeptide molecules. Calculation of the percent identity of two polynucleotide sequences, for example, can be performed by aligning the two sequences for optimal comparison purposes (e.g., gaps can be introduced in one or both of a first and a second nucleic acid sequences for optimal alignment and non-identical sequences can be disregarded for comparison purposes). In certain embodiments, the length of a sequence aligned for comparison purposes is at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or 100% of the length of the reference sequence. The nucleotides at corresponding nucleotide positions are then compared. When a position in the first sequence is occupied by the same nucleotide as the corresponding position in the second sequence, then the molecules are identical at that position. The percent identity between the two sequences is a function of the number of identical positions shared by the sequences, taking into account the number of gaps, and the length of each gap, which needs to be introduced for optimal alignment of the two sequences. The comparison of sequences and determination of percent identity between two sequences can be accomplished using a mathematical algorithm. For example, the percent identity between two nucleotide sequences can be determined using methods such as those described in Computational Molecular Biology, Lesk, A. M., ed., Oxford University Press, New York, 1988; Biocomputing: Informatics and Genome Projects, Smith, D. W., ed., Academic Press, New York, 1993; Sequence Analysis in Molecular Biology, von Heinje, G., Academic Press, 1987; Computer Analysis of Sequence Data. Part I, Griffin, A. M., and Griffin, H. G., eds., Humana Press, New Jersey, 1994; and Sequence Analysis Primer. Gribskov, M. and Devereux, J., eds., M Stockton Press, New York, 1991; each of which is incorporated herein by reference. For example, the percent identity between two nucleotide sequences can be determined using the algorithm of Meyers and Miller (CABIOS, 1989, 4:11-17), which has been incorporated into the ALIGN program (version 2.0) using a PAM120 weight residue table, a gap length penalty of 12 and a gap penalty of 4. The percent identity between two nucleotide sequences can, alternatively, be determined using the GAP program in the GCG software package using an NWSgapdna.CMP matrix. Methods commonly employed to determine percent identity between sequences include, but are not limited to those disclosed in Carillo, H. and Lipman, D., SIAM J Applied Math., 48:1073 (1988); incorporated herein by reference. Techniques for determining identity are codified in publicly available computer programs. Exemplary computer software to determine homology between two sequences include, but are not limited to, GCG program package, Devereux, J., et al., Nucleic Acids Research, 12(1), 387 (1984)), BLASTP, BLASTN, and FASTA Altschul, S. F. et al., J. Molec. Biol., 215, 403 (1990)).

The level of transgene expression by AAV particles and/or VAPs produced and purified by the methods described herein is determined by real-time quantitative polymerase chain reaction (qPCR). A culture of cells (sf9 or HEK293) engineered to produce helper components required for AAV production is infected by AAV particles and/or VAPs produced as described herein.
The target cells are harvested at a series of time points, lysed and the mRNA is purified. The level of transgene expressed is determined by reverse transcription (qPCR) on a thermal cycler equipped with an excitation source filters, and detector for quantification of the reaction such as, but not limited to, the 7500 FAST Real-Time PCR system (Applied Biosystems, Foster City Calif.).
AAV particles and/or VAPs produced and purified by the methods described herein are treated with proteinase K, serially diluted, and PCR-amplified using a fluor such as, but not limited to, SYBR green (Applied Biosystems, Foster City. Calif.) with primers specific to the transgene sequence. A reference transgene oligonucleotide is used as a copy number standard. The cycling conditions are: 95° C. for 3 min, followed by 35 cycles of 95° C. for 30 sec, 60° C. for 30 sec. and 72° C. for 30 sec.
The viral construct vector encodes the three structural cap proteins, VP1, VP2, and VP3, in a single open reading frame regulated by utilization of both alternative splice acceptor and non-canonical translational initiation codon(s). In-frame and out-of-frame ATG triplets preventing translation initiation at a position between the VP1 and VP2 start codons are eliminated. Both Rep78 and Rep52 are translated from a single transcript: Rep78 translation initiates at a non-AUG codon and Rep52 translation initiates at the first AUG in the transcript.
The nucleotides that encode the structural VP1, VP2, and VP3 capsid proteins and non-structural Rep78 and Rep52 proteins are contained on one viral expression construct under control of the baculovirus major late promoter.
The payload construct vector encodes two ITR sequences flanking a transgene polynucleotide encoding a polypeptide or modulatory nucleic acid and/or one or more regulatable elements. The ITR sequences allow for replication of a polynucleotide encoding the transgene and ITR sequences alone that will be packaged within the capsid of the viral construct vector. The replicated polynucleotide encodes ITR sequences on the 5′ and 3′ ends of the molecule.
The payload construct vector and viral construct vector each comprise a Tn7 transposon element that transposes the ITR and payload sequences or the Rep and Cap sequences respectively to a bacmid that comprises the attTn7 attachment site. Competent bacterial DH10 cells are transfected with either the payload construct vector or viral construct vector. The resultant viral construct expression vector and payload construct expression vector produced in the competent cell are then purified by detergent lysis and purification on DNA columns.
Separate seed cultures of Sf9 cells in serum free suspension culture are transfected with the viral construct expression vector or payload construct expression vector. The cultures are maintained for 48 hours while baculovirus is produced and released into the medium. The baculovirus released into the media continue to infect Sf9 cells in an exponential manner until all of the Sf9 cells in the culture are infected at least once. The baculoviral infected insect cells (BIIC) and media of the seed culture is harvested and divided into aliquots before being frozen in liquid nitrogen.
A naïve population of un-transfected Sf9 cells is expanded in serum free suspension cell culture conditions. Once the culture growth has reached peak log phase in 1 L of media as measured by optical density the culture is added to a large volume 20 L bioreactor. The bioreactor culture is co-inoculated with a frozen viral construct expression vector and payload construct expression vector BIIC aliquot. The conditions of the Sf9 cell suspension culture is monitored by instruments that measure and/or control external variables that support the growth and activity of viral replication cells such as mass, temperature, CO2, O2, pH, and/or optical density (OD). The Sf9 culture is maintained at optimal conditions until cell population growth has reached peak log phase and before cell growth has plateaued, as measured by optical density.
In each viral replication cell that has been infected with both baculoviruses the payload flanked on one end with an ITR sequence is replicated pathway producing a viral genome and packaged in a capsid assembled from the proteins VP1, VP2, and VP3.
The viral replication cells are lysed using the Microfluidizer™ (Microfluidics International Corp., Newton, Mass.), high shear force fluid processor. The resultant cell lysate is clarified by low speed centrifugation followed by tangential flow filtration. The resultant clarified lysate is filtered by a size exclusion column to remove any remaining baculoviral particles from solution. The final steps utilize ultracentrifugation and sterile filtration to produce viral particles suitable for use as described herein.
The titer of AAV particles produced and purified by the methods described herein is determined by real-time quantitative polymerase chain reaction (qPCR) on a thermal cycler equipped with an excitation source filters, and detector for quantification of the reaction such as, but not limited to, the 7500 FAST Real-Time PCR system (Applied Biosystems, Foster City Calif.). AAV particles produced and purified by the methods described herein is treated with proteinase K, serially diluted, and PCR-amplified using a fluor such as, but not limited to, SYBR green (Applied Biosystems, Foster City, Calif.) with primers specific to the AAV genome ITR sequences. A linearized viral genome is used as a copy number standard. The cycling conditions are: 95° C. for 3 min, followed by 35 cycles of 95° C. for 30 sec, 60° C. for 30 sec, and 72° C. for 30 sec.
In order to study methods to induce transient, burst expression of cas9, an AAV particle of Example 2 which encodes cas9, a DNA binding domain and a transactivating factor is prepared, produced and tested by methods known in the art and described herein. The cas9 sequence is located in the open reading frame of the vector and a DNA binding domain (DBD) and transactivating factor are located in VP2. The transactivating factor may be coupled to the DBD.
The DBD may be a pre-engineered DBD targeted specifically to the promoter used for cas9. While not wishing to be bound by theory, upon expression of VP2 in a biological system, the DBD locates and binds to the cas9 promoter. If the transactivating factor is for cas9 and the transactivating factor is coupled to the DBD, upon DBD binding to the cas9 promoter, the transactivating factor drives expression of cas9.
The nature of the interaction between the promoter and the DBD coupled to a transactivating factor generates a transient, burst expression of cas9. This punctuated expression may be beneficial as it may limit the possibility of side-effects of extended elevated expression of cas9.
To study the burst expression of cas9, an AAV particle with the DBD and the transactivating factor is purified and produced as described in Example 2. As a control, an AAV particle lacking the DBD and transactivating domain is produced in parallel.
Expression of cas9 is measured by methods described herein and known in the art, such as in HEK293 cells for the AAV particle with or without the DBD and transactivating factor. Cells are lysed at different time points and protein extracts are prepared for ELISA and Western blot analysis.
The specificity of cas9 cleavage is confirmed by deep sequencing of samples collected and the extent of dsDNA cleavage by cas9 or cas9-destabilizing domain fusion protein is measured by ligation-mediated purification or genome modification assays such as SURVEYOR. Indel percentage is calculated from the integrated intensities of the undigested PCR product and each of the cleavage products.
The ability of a CRISPR regulatable elements to regulate the expression of a luciferase payload composed of one or more CRISPR recognition sequences is tested in vitro and in vivo. Cleavage of the payload construct at the CRISPR recognition sequence ablates the payload expression. Using Cas9 with a destabilizing domain shortens the half-life of Cas9.
The following CRISPR-AAV constructs are prepared, produced and tested.
AAV construct 1 encodes a luciferase payload, which is driven by a constitutive promoter and which contains a CRISPR recognition sequence. The recognition sequence is chosen using methods known in the art and described herein to ensure that the sequence is unique to the viral genome and does not occur in the host genome. The AAV construct 2, which contains all of the components of construct 1, and additionally encodes a guide RNA specific to the CRISPR recognition sequence in the luciferase payload and a codon optimized Cas9 with a destabilizing domain. The guide RNA and Cas9 are both expressed from a constitutive promotor. Cas9 also contains a nuclear localization sequence. AAV construct 3 encodes luciferase driven by a CMV promoter without the CRISPR recognition sequence (positive control). AAV construct 4 contains all of the elements of construct 3, and further encodes a guide RNA specific to the CRISPR recognition sequence located in the luciferase payload and a Cas9 with a destabilizing domain. The guide RNA and Cas9 are both expressed from a constitutive promotor. Cas9 also contains a nuclear localization sequence.
In one example, two AAV vectors are used for transduction, one expressing the regulatable elements (Cas9 and guide RNA) and the other expressing the luciferase payload. These two vectors are delivered at a ratio determined to be optimal. Alternatively, one vector is used for transduction, expressing the regulatable elements and the luciferase payload.
HeLa cells are transduced with the AAV vector(s) constructs 1 through 4, according to methods known in the art in triplicate for each assay. The transduced HeLa cells are incubated in medium. Subsequently, cells are harvested according to a time course which includes 24, 48, and 72 hours. The cells are lysed and luciferase activity is measured and compared between the samples.
If the regulatable elements and the luciferase payload are on two separate vectors, the effective dose of the CRISPR regulatable element is determined. HeLa cells are transduced with construct 1 and different doses of the AAV vector encoding Cas9 and the guide RNA, each in triplicate. Cells are harvested, lysed and luciferase activity is measured for each dose of Cas9 and guide RNA employed.
The AAV constructs 1 and 2 are prepared, produced and tested. AAV particles 1 and 2 are each injected into mice of 3 to 5 months of age according to methods known in the art. At a set time post injection, such as for example 2 weeks, mice are injected with luciferin. Animals are then anesthetized, and images are acquired with an imaging system. Bioluminescence is measured as total flux (photons/second) of the entire mouse and compared between the samples.
The ability of an inducible system to regulate a CRISPR regulatable element, which in turn can regulate the payload in the context of AAV transduction is tested in vitro and in vivo. The ability of a regulatable element composed of two rapamycin inducible fusion proteins to regulate the expression of a CRISPR regulatable element is tested in vitro.
The following CRISPR-AAV constructs are prepared, produced and tested. AAV construct 1 encodes a luciferase payload, which contains a CRISPR recognition sequence, driven by a constitutive promoter. The recognition sequence is chosen using methods known in the art and described herein to ensure that the sequence is unique to the viral genome and does not occur in the host genome. AAV construct 2 contains the components of construct 1 and additionally encodes a guide RNA specific to the CRISPR recognition sequence located in the luciferase payload and a codon optimized Cas9 with a destabilizing domain. The guide RNA and Cas9 are both expressed from a constitutive promotor. Cas9 also contains a nuclear localization sequence. AAV construct 3 contains all of the components of construct 1, and additionally encodes a guide RNA specific to the CRISPR recognition sequence located in the luciferase payload and a codon optimized Cas9 with a destabilizing domain. The guide RNA and Cas9 are both expressed from a minimal promotor into which one or more ZHFD1 binding sites are inserted. Cas9 also contains a nuclear localization sequence. AAV construct 4 contains all of the components of construct 3, and additionally encodes two dimerizable fusion proteins, FKBP containing the DNA-binding domain of ZHFD1 and FRAP fused to the NF-kappaB p65 transactivation domain. The dimerizable fusion proteins are expressed from one constitutive promotor, and linked together through a 2A peptide sequence. The transcription factor and the transactivation domain fusion proteins both contain a nuclear localization sequence.
Two or more AAV vectors can be used for transduction, one or more expressing the regulatable elements (Cas9 and guide RNA, and dimerizable fusion proteins) and an additional vector expressing the luciferase payload. Alternatively, three AAV vectors are used, one encoding the CRISPR regulatable elements, one encoding the dimerizable fusion proteins, and one encoding the luciferase payload. These vectors are delivered at a ratio determined to be optimal. In another embodiment, one vector is used for transduction, expressing the regulatable elements and the luciferase payload. In some embodiments, an open reading frame for the DNA binding domain fusion protein and/or transactivation domain fusion protein is located in VP2.
HeLa cells are transduced with the AAV vector constructs 1 through 4, according to methods known in the art in triplicate for each assay. The transduced HeLa cells are incubated in medium in the presence or absence of rapamycin for a set time. Subsequently, cells are harvested according to a time course which includes 24, 48, and 72 hours. The cells are lysed and luciferase activity is measured. Throughout the time course, luciferase activity is compared between untreated and rapamycin treated samples for each AAV vector construct and also between samples transduced with the vector constructs 1 through 4.
The AAV constructs 1-4 are prepared, produced and tested. In addition, a 5th construct may be added, which is the same as 4, except that the fusion proteins are driven by a tissue specific promoter, such as a liver specific promoter. AAV particles 1-4 are each injected into two mice of 3 to 5 months of age according to methods known in the art. At approximately 2 weeks post injection, a further injection of rapamycin is administered to half of the mice. At a predetermined time, mice are injected with luciferin. Animals are then anesthetized and images are acquired with an imaging system. Bioluminescence is measured as total flux (photons/second) of the entire mouse. Luciferase activity is compared between untreated and rapamycin treated animals and also between animals injected with the AAV particles 1-4.
