DETAILED DESCRIPTION
I. ADENO-ASSOCIATED VIRUSES (AAVs)
Overview

Adeno-associated viruses (AAV) are small non-enveloped icosahedral capsid viruses of the Parvoviridae family characterized by a single stranded DNA viral 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 comprises AAV, capable of replication in vertebrate hosts comprising, 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 I. Berns, “Parvoviridae: The Viruses and Their Replication,” Chapter 69 in Fields Virology (3d Ed. 1996), the content of which is incorporated herein by reference in its entirety as related to parvoviruses, insofar as it does not conflict with the present disclosure.


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 (comprising 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.


AAV Viral Genomes

The wild-type AAV viral genome is a linear, single-stranded DNA (ssDNA) molecule approximately 5,000 nucleotides (nt) in length. Inverted terminal repeats (ITRs) traditionally cap the viral genome at both the 5′ and the 3′ end, providing origins of replication for the viral genome. While not wishing to be bound by theory, an AAV viral genome typically comprises two ITR sequences. These ITRs have a characteristic T-shaped hairpin structure defined by a self-complementary region (145 nt 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 comprising, 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 viral 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 NO: 123 of U.S. Pat. No. 7,906,111, the content of which is incorporated herein by reference in its entirety as related to AAV9/hu.14, insofar as it does not conflict with the present disclosure) VP1 refers to amino acids 1-736, \/P2 refers to amino acids 138-736, and VP3 refers to amino acids 203-736. In other words, VPT 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 \/P3 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 viral 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 viral genomes there are two ITR regions. The rep/cap sequences can be provided in trans during production to generate AAV particles.


In addition to the encoded heterologous payload, AAV vectors may comprise the viral 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. See Chiorini et al., J. Vir. 71: 6823-33(1997); Srivastava et al., J. Vir. 45:555-64 (1983); Chiorini et al., J. Vir. 73:1309-1319 (1999); Rutledge et al., J. Vir. 72:309-319 (1998); and Wu et al., J. Vir. 74: 8635-47 (2000), the contents of each of which are incorporated herein by reference in their entireties as related to AAV variants and equivalents, insofar as they do not conflict with the present disclosure.


In certain embodiments, AAV particles, viral genomes and/or payloads of the present disclosure, and the methods of their use, may be as described in WO2017189963, the content of which is incorporated herein by reference in its entirety as related to AAV particles, viral genomes and/or payloads, insofar as it does not conflict with the present disclosure.


AAV particles of the present disclosure may he formulated in any of the gene therapy formulations of the disclosure comprising any variations of such formulations apparent to those skilled in the art.

In certain embodiments, the viral genome of the AAV particles of the present disclosure comprises 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 comprise 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 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 are engineered as vehicles for specific delivery while lacking the deleterious replication and/or integration features found in wild-type viruses.


AAV particles of the present disclosure may be produced recombinantly and may be based on adeno-associated virus (AAV) parent or reference sequences. As used herein, a “vector” is any molecule or moiety which transports, transduces or otherwise acts as a carrier of a heterologous molecule such as the nucleic acids described herein.


In addition to single stranded AAV viral genomes (e.g., ssAAVs), the present disclosure also provides for self-complementary AAV (scAAVs) viral 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 cell.

AAV particles may be modified to enhance the efficiency of delivery. Such modified AAV particles can he packaged efficiently and be used to successfully infect the target cells at high frequency and with minimal toxicity. In certain embodiments the capsids of the AAV particles are engineered according to the methods described in US Publication Number US 20130195801, the content of which is incorporated herein by reference in its entirety as related to modifying AAV particles to enhance the efficiency of delivery, insofar as it does not conflict with the present disclosure.

The length of the enhancer region for the viral genome may be 300-310, 300-325, 305-315, 310-320, 315-325, 320-330, 325-335, 325-350, 330-340, 335-345, 340-350, 345-355, 350-360, 350-375, 355-365, 360-370, 365-375, 370-380, 375-385, 375-400, 380-390, 385-395, and 390-400 nucleotides, As a non-limiting example, the viral genome comprises an enhancer region that is about 303 nucleotides in length. As a non-limiting example, the viral genome comprises an enhancer region that is about 382 nucleotides in length.


In certain embodiments, the enhancer region is derived from a CMV enhancer sequence. As a non-limiting example, the CMV enhancer is 382 nucleotides in length.


Untranslated Regions (UT)

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 viral genomes of the AAV particles of the present disclosure to enhance expression in hepatic cell lines or liver.


While not wishing to be bound by theory, wild-type 5′ untranslated regions (UTRs) comprise 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 comprised 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 certain embodiments, the 5′ UTR in the viral genome comprises a Kozak sequence. In certain embodiments, the 5′ UTR in the viral genome does not comprise 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 content of which is incorporated herein by reference in its entirety as related to AU rich elements, insofar as it does not conflict with the present disclosure): 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 viva.


Introduction, removal or modification of 3′ UTR AU rich elements (AREs) can be used to modulate the stability of polynucleotides. When engineering specific polynucleotides, (e.g., payload regions of viral genomes), one or more copies of an ARE can be introduced to make polynucleotides less stable and thereby curtail translation and decrease production of the resultant protein. Likewise, AREs can be identified and removed or mutated to increase the intracellular stability and thus increase translation and production of the resultant protein.


In certain embodiments, the 3′ UTR of the viral genome may comprise an oligo(dT) sequence for templated addition of a poly-A tail.


In certain embodiments, the viral genome may comprise 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 certain embodiments, the viral genome may be engineered to comprise, alter or remove at least one miRNA binding site, sequence or seed region.


Any UTR from any gene known in the art may he incorporated into the viral genome of the AAV particle. 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 certain embodiments, the UTR used in the viral genome of the AAV particle 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 certain embodiments, the viral genome of the AAV particle comprises at least one artificial UTRs which is not a variant of a wild type UTR.


In certain embodiments, the viral genome of the AAV particle comprises UTRs which have been selected from a family of transcripts whose proteins share a common function, structure, feature or property.


Polyadenylation Sequence

In certain embodiments, the viral genome of the AAV particles of the present disclosure comprise at least one polyadenylation sequence. The viral genome of the AAV particle may comprise a polyadenylation sequence between the 3′ end of the payload coding sequence and the 5′ end of the 3′ ITR.


In certain embodiments, the polyadenylation sequence or “polyA sequence” may range from absent to about 500 nucleotides in length. The polyadenylation sequence may be, but is not limited to, 1-500 nucleotides in length (or any value or range therein),


In certain embodiments, the polyadenylation sequence is 127 nucleotides in length. In certain embodiments, the polyadenylation sequences is 477 nucleotides in length. In certain embodiments, the polyadenylation sequence is 552 nucleotides in length.


Linkers

Viral genomes of the present disclosure may be engineered with one or more spacer or linker regions to separate coding or non-coding regions.


In certain embodiments, the payload region of the AAV particle 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 polypeptide domains, allowing assembly of mature protein fragments. 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 (e.g., heavy and light chain antibody domains) from a single transcript. In some cases, two or more linkers are encoded by a payload region of the viral genome.


In certain embodiments, 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-(Arglys)-Arg) (Thomas, G., 2002. Nature Reviews Molecular Cell Biology 3(10): 753-66; the content of which is incorporated herein by reference in its entirety as related to linker molecules or sequences, insofar as it does not conflict with the present disclosure). 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 of the disclosure.


In certain embodiments, payload regions encode linkers comprising 2A peptides. 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 picomavims polyproteins that lead to a ribosomal skip at the glycyl-prolyl bond in the C-terminus of the 2A peptide (Kim, et al.. 2011. PLoS One 6(4): e18556; the content of which is incorporated herein by reference in its entirety as related to 2A peptide linkers, insofar as it does not conflict with the present disclosure). 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.


In certain embodiments, payload regions encode linkers comprising IRES. 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 content of which is incorporated herein by reference in its entirety as related to IRES regions and linkers, insofar as it does not conflict with the present disclosure). 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 certain 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 content of which is incorporated herein by reference in its entirety as related to linker molecules and sequences, insofar as it does not conflict with the present disclosure. 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 certain embodiments, payload regions may encode linkers that are not cleaved. Such linkers may comprise 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. 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 at, 1988. PNAS 85:5879-83; and Shan, D. et al., 1999. Journal of Immunology. 162(11):6589-95; the contents of which are each incorporated herein by reference in their entireties as related to linker molecules and sequences, insofar as they do not conflict with the present disclosure). Furthermore, the polarity of the serine residues improves solubility and prevents aggregation problems.


In certain embodiments, payload regions of the present disclosure 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 content of which is incorporated herein by reference in its entirety as related to linker molecules and sequences, insofar as it does not conflict with the present disclosure. Polypeptides encoded by the payload region of the present disclosure, linked by serine-rich linkers, have increased solubility.


In certain embodiments, payload regions of the present disclosure 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 which are each incorporated herein by reference in their entireties as related to linker molecules and sequences, insofar as they do not conflict with the present disclosure.


In certain 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 1-650 nucleotides (or any value or range therein) r greater than 650. In certain embodiments, the linker region may he 12 nucleotides in length. In certain embodiments, the linker region may be 18 nucleotides in length. In certain embodiments, the linker region may be 45 nucleotides in length. In certain embodiments, the linker region may be 54 nucleotides in length. In certain embodiments, the linker region may be 66 nucleotides in length. In certain embodiments, the linker region may be 75 nucleotides in length. In certain embodiments, the linker region may be 78 nucleotides in length. In certain embodiments, the linker region may be 87 nucleotides in length. In certain embodiments, the linker region may be 108 nucleotides in length. In certain embodiments, the linker region may be 153 nucleotides in length. In certain embodiments, the linker region may be 198 nucleotides in length. In certain embodiments, the linker region may be 623 nucleotides in length.

In certain embodiments, the initiation codon for translation of the AAV VP1 capsid protein may be CTG, TTG, or GTG as described in U.S. Pat. No. 8,163,543 (the content of which is incorporated herein by reference in its entirety as related to AAV capsids and start codons, insofar as it does not conflict with the present disclosure).


The present disclosure refers to structural capsid proteins (comprising 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 comprise 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 comprise 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 incorporated herein by reference in their entireties as related to Met/AA-clipping in capsid proteins, insofar as they do not conflict with the present disclosure.


According to the present disclosure, references to capsid proteins are not limited to either clipped (Met−/AA−) or unclipped (Met+/AA+) sequences 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 VP3) may also comprise VP capsid proteins which comprise a Met1/AA1 amino acid (Met+/AA+) as well as corresponding VP capsid proteins which lack the Met1/AA1amino 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) that comprises or encodes, respectively, one or more capsid proteins that comprise a Met1/AA1amino acid (Met+/AA+) should be understood to teach the VP capsid proteins that lack the Met1/AA1 amino acid as upon review of the sequence, it is readily apparent any sequence that merely lacks the first listed amino acid (whether or not methionine).


As a non-limiting example, reference to a VP1 polypeptide sequence which is 736 amino acids in length and which comprises a “Met1” amino acid (Met+) encoded by the AUG/ATG start codon may also be understood to teach a VP1 polypeptide sequence that is 735 amino acids in length and that does not comprise the “Met1” amino acid (Met−) of the 736 amino acid Met+ sequence. As a second non-limiting example, reference to a VP1 polypeptide sequence that is 736 amino acids in length and that comprises an “AA1” amino acid (AA1+) encoded by any NNN initiator codon may also be understood to teach a VP1 polypeptide sequence that is 735 amino acids in length and that does not comprise the “AA1” amino acid (AA1−) of the 736 amino acid AA1+ sequence.


References to viral capsids foamed. from VP capsid proteins (such as reference to specific AAV capsid serotypes) can incorporate VP capsid proteins that comprise a Met1/AA1 amino acid (Met+/AA1+), corresponding VP capsid proteins that lack the Met1/AA1 amino acid as a result of Met/AA1-clipping (Met−/AA1−), or combinations thereof (Met+/AA1+ and Met−/AA1−).


As a non-limiting example, an AAV capsid serotype can comprise VP1 (Met+/AA1+), VP1 (Met−/AA1−), or a combination of VP1 (Met+/AA1+) and VP1 (Met-/AA1−). An AAV capsid serotype can also comprise VP3 (Met+/AA1+), VP3 (Met−/AA1−), or a combination of VP3 (Met+/AA1+) and VP3 (Met−/AA1−); and can also comprise similar optional combinations of VP2 (Met+/AA1) and VP2 (Met−/AA1−).

Amino acid sequences encoded by payload regions of the viral genomes of the disclosure 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 comprise 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.


In certain embodiments a “polypeptide variant” is provided. 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 in certain embodiments, they will be at least about 80%, or at least about 90% identical (homologous) to a native or reference sequence.


The present disclosure comprises the use of formulated AAV particles whose vector genomes encode modulatory polynucleotides, e.g., RNA or DNA molecules as therapeutic agents. Accordingly, the present disclosure provides vector genomes which encode polynucleotides which are processed into small double stranded RNA (dsRNA) molecules (small interfering RNA, siRNA, miRNA, pre-miRNA) targeting a gene of interest. The present disclosure also provides methods of their use for inhibiting gene expression and protein production of an allele of the gene of interest, for treating diseases, disorders, and/or conditions.


In certain embodiments, the AAV particle comprises a viral genome with a payload region comprising a nucleic acid sequence encoding or comprising one or more modulatory polynucleotides. In certain embodiments, the AAV particle comprises a viral genome with a payload region comprising a nucleic acid sequence encoding a modulatory polynucleotide of interest. In certain embodiments of the present disclosure, modulatory polynucleotides, e.g, RNA or DNA molecules, are presented as therapeutic agents. RNA interference mediated gene silencing can specifically inhibit targeted gene expression.


In certain embodiments, the payload region comprises a nucleic acid sequence encoding a modulatory polynucleotide which interferes with a target gene expression and/or a target protein production. In certain embodiments, the gene expression or protein production to be inhibited/modified may comprise but are not limited to superoxide dismutase 1 (SOD1), chromosome 9 open reading frame 72 (C9ORF72), TAR DNA binding protein (TARDBP), ataxin-3 (ATXN3), huntingtin amyloid precursor protein (APP), apolipoprotein E (ApoE), microtubule-associated protein tau (MAPT), alpha-synuclein (SNCA), voltage-gated sodium channel alpha subunit 9 (SCN9A), and/or voltage-gated sodium channel alpha subunit 10 (SCN10A).


In certain embodiments, the AAV particle comprises a viral genome with a payload region comprising a nucleic acid sequence encoding any of the modulatory polynucleotides, RNAi molecules, siRNA molecules, dsRNA molecules, and/or RNA duplexes described in any one of the following International Publications: WO2016073693, WO2017023724, WO2016077687, WO2016077689, WO2018204786, WO2017201258, WO2017201248, WO2018204803, WO2018204797, WO2017189959, WO2017189963, WO2017189964, WO2015191508, WO2016094783, WO20160137949, WO2017075335; the contents of which are each incorporated herein by reference in their entireties insofar as they do not conflict with the present disclosure.


In certain embodiments, a nucleic acid sequence encoding such siRNA. molecules, or a single strand of the siRNA molecules, is inserted into adeno-associated viral vectors and introduced into cells, specifically cells in the central nervous system.


AAV particles have been investigated for siRNA delivery because of several unique features. Non-limiting examples of the features comprise (i) the ability to infect both dividing and non-dividing cells; (ii) a broad host range for infectivity, comprising human cells; (iii) wild-type AAV has not been associated with any disease and has not been shown to replicate in infected cells; (iv) the lack of cell-mediated immune response against the vector and (v) the non-integrative nature in a host chromosome thereby reducing potential for long-term expression. Moreover, infection with AAV particles has minimal influence on changing the pattern of cellular gene expression (Stilwell and Samulski et al., Biotechniques, 2003, 34, 148).


In certain embodiments, the encoded siRNA duplex of the present disclosure contains an antisense strand and a sense strand hybridized together forming a duplex structure, wherein the antisense strand is complementary to the nucleic acid sequence of the targeted gene of interest, and wherein the sense strand is homologous to the nucleic acid sequence of the targeted gene of interest. In other aspects, there are 0, 1 or 2 nucleotide overhangs at the 3′end of each strand.


The payloads of the formulated AAV particles of the present disclosure may encode one or more agents which are subject to RNA interference (RNAi) induced inhibition of gene expression. Provided herein are encoded siRNA duplexes or encoded dsRNA that target a gene of interest (referred to herein collectively as “siRNA molecules”). Such siRNA molecules, e.g., encoded siRNA duplexes, encoded dsRNA or encoded siRNA or dsRNA precursors can reduce or silence gene expression in cells, for example, astrocytes or microglia, cortical, hippocampal, entorhinal, thalamic, sensory or motor neurons.


RNAi (also known as post-transcriptional gene silencing (PIGS), quelling, or co-suppression) is a post-transcriptional gene silencing process in which RNA molecules, in a sequence specific manner, inhibit gene expression, typically by causing the destruction of specific mRNA molecules. The active components of RNAi are short/small double stranded RNAs (dsRNAs), called small interfering RNAs (siRNAs), that typically contain 15-30 nucleotides (e.g., 19 to 25, 19 to 24 or 19-21 nucleotides) and 2-nucleotide 3′ overhangs and that match the nucleic acid sequence of the target gene. These short RNA species may be naturally produced in vivo by Dicer-mediated cleavage of larger dsRNAs and they are functional in mammalian cells.


Naturally expressed small RNA molecules, known as microRNAs (miRNAs), elicit gene silencing by regulating the expression of mRNAs. The miRNAs containing RNA Induced Silencing Complex (RISC) targets mRNAs presenting a perfect sequence complementarity with nucleotides 2-7 in the 5′ region of the miRNA which is called the seed region, and other base pairs with its 3′ region. miRNA mediated down regulation of gene expression may he caused by cleavage of the target mRNAs, translational inhibition of the target mRNAs, or mRNA decay. miRNA targeting sequences are usually located in the 3′ UTR of the target mRNAs. A single miRNA may target more than 100 transcripts from various genes, and one mRNA may be targeted by different miRNAs.


siRNA duplexes or dsRNA targeting a specific mRNA may be designed as a payload of an AAV particle and introduced into cells for activating RNAi processes. Elbashir et al. demonstrated that 21-nucleotide siRNA duplexes (termed small interfering RNAs) were capable of effecting potent and specific gene knockdown without inducing immune response in mammalian cells (Elbashir S M et al., Nature, 2001, 411, 494-498), Since this initial report, post-transcriptional gene silencing by siRNAs quickly emerged as a powerful tool for genetic analysis in mammalian cells and has the potential to produce novel therapeutics.


The siRNA duplex comprised of a sense strand homologous to the target mRNA and an antisense strand that is complementary to the target mRNA offers much more advantage in terms of efficiency for target RNA destruction compared to the use of the single strand (ss)-siRNAs (e.g. antisense strand RNA or antisense oligonucleotides). In many cases it requires higher concentration of the ss-siRNA to achieve the effective gene silencing potency of the corresponding duplex.


In certain embodiments, the siRNA molecules may be encoded in a modulatory polynucleotide which also comprises a molecular scaffold. As used herein a “molecular scaffold” is a framework or starting molecule that forms the sequence or structural basis against which to design or make a subsequent molecule.


In certain embodiments, the modulatory polynucleotide which comprises the payload (e.g., siRNA, miRNA or other RNAi agent described herein) comprises molecular scaffold which comprises a leading 5′ flanking sequence which may be of any length and may be derived in whole or in part from wild type microRNA sequence or be completely artificial. A 3′ flanking sequence may mirror the 5′ flanking sequence in size and origin. In certain embodiments, one or both of the 5′ and 3′ flanking sequences are absent.


In certain embodiments, the molecular scaffold may comprise one or more linkers known in the art. The linkers may separate regions or one molecular scaffold from another. As a non-limiting example, the molecular scaffold may be polycistronic.


In certain embodiments, the modulatory polynucleotide is designed using at least one of the following properties: loop variant, seed mismatch/bulge/wobble variant, stern mismatch, loop variant and basal stem mismatch variant, seed mismatch and basal stem mismatch variant, stem mismatch and basal stem mismatch variant, seed wobble and basal stem wobble variant, or a stem sequence variant.

In certain 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.


In certain embodiments an “amino acid sequence variant” is provided. 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 he 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 in certain embodiments, they will be at least about 80% or 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 maximwn 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 comprise 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 of the disclosure (e.g., at the N-terminal or C-terminal ends). Sequence tags can he 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 he 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.


In certain embodiments a “substitutional variant” is provided. “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 comprise the substitution of a non-polar (hydrophobic) residue such as isoleucine, valine and leucine for another non-polar residue. Likewise, examples of conservative substitutions comprise 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 comprise 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.


In certain embodiments an “insertional variant” is provided. “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.


In certain embodiments a “deletional variant” is provided. “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 certain embodiments, derivatives comprise 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 aspartylresidues. 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 comprise 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 comprise 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 comprise beta sheets and alpha helices. Examples of tertiary folds comprise domains and regions formed due to aggregation or separation of energetic forces. Regions formed in this way comprise hydrophobic and hydrophilic pockets, and the like.


As used herein the terns “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+1−0.5 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 comprise 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 of the disclosure are in certain embodiments 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 he 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 of the disclosure, 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 of the disclosure. 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.

In certain embodiments, a nucleic acid sequence encoding such siRNA molecules, or a single strand of the siRNA molecules, is inserted into adeno-associated viral vectors and introduced into cells, specifically cells in the central nervous system.


AAV particles have been investigated for siRNA delivery because of several unique features. Non-limiting examples of the features comprise (i) the ability to infect both dividing and non-dividing cells; (ii) a broad host range for infectivity, comprising human cells; (iii) AAV has not been associated with any disease and has not been shown to replicate in infected cells; (iv) the lack of cell-mediated immune response against the vector and (v) the non-integrative nature in a host chromosome thereby reducing potential for long-term expression. Moreover, infection with AAV particles has minimal influence on changing the pattern of cellular gene expression (Stilwell and Samulski et al., Biotechniques, 2003, 34, 148).

siRNA Molecules


The payloads of the formulated AAV particles of the present disclosure may encode one or more agents which are subject to RNA interference (RNAi) induced inhibition of gene expression. Provided herein are encoded siRNA duplexes or encoded dsRNA that target a gene of interest (referred to herein collectively as “siRNA molecules”). Such siRNA molecules, e.g., encoded siRNA duplexes, encoded dsRNA or encoded siRNA or dsRNA precursors can reduce or silence gene expression in cells, for example, astrocytes or microglia, cortical, hippocampal, entorhinal, thalamic, sensory or motor neurons.


RNAi (also known as post-transcriptional gene silencing (PTGS), quelling, or co-suppression) is a post-transcriptional gene silencing process in which RNA molecules, in a sequence specific manner, inhibit gene expression, typically by causing the destruction of specific mRNA molecules. The active components of RNAi are short/small double stranded RNAs (dsRNAs), called small interfering RNAs (siRNAs), that typically contain 15-30 nucleotides (e.g., 19 to 25, 19 to 24 or 19-21 nucleotides) and 2-nucleotide 3′ overhangs and. that match the nucleic acid sequence of the target gene. These short RNA species may be naturally produced in vivo by Dicer-mediated cleavage of larger dsRNAs and they are functional in mammalian cells.


Naturally expressed small. RNA molecules, known as microRNAs (miRNAs), elicit gene silencing by regulating the expression of mRNAs. The miRNAs containing RNA Induced Silencing Complex (RISC) targets mRNAs presenting a perfect sequence complementarity with nucleotides 2-7 in the 5′ region of the miRNA which is called the seed region, and other base pairs with its 3′ region, miRNA mediated down regulation of gene expression may be caused by cleavage of the target mRNAs, translational inhibition of the target mRNAs, or mRNA decay. miRNA targeting sequences are usually located in the 3′ UTR of the target mRNAs. A single miRNA may target more than 100 transcripts from various genes, and one mRNA may be targeted by different miRNAs.


siRNA duplexes or dsRNA targeting a specific mRNA may be designed as a payload of an AAV particle and introduced into cells for activating RNAi processes. Elbashir et al, demonstrated that 21-nucleotide siRNA duplexes (termed small interfering RNAs) were capable of effecting potent and specific gene knockdown without inducing immune response in mammalian cells (Elbashir S M et al., Nature, 2001, 411, 494-498). Since this initial report, post-transcriptional gene silencing by siRNAs quickly emerged as a powerful. tool for genetic analysis in mammalian cells and has the potential to produce novel therapeutics.


The siRNA duplex comprised of a sense strand homologous to the target mRNA and an antisense strand that is complementary to the target mRNA offers much more advantage in terms of efficiency for target RNA destruction compared to the use of the single strand (ss)-siRNAs (e.g. antisense strand RNA or antisense oligonucleotides). In many cases it requires higher concentration of the ss-siRNA to achieve the effective gene silencing potency of the corresponding duplex.


Any of the foregoing molecules may be encoded by an AAV particle or vector genome.


Design and Sequences of siRNA Duplexes Targeting a Gene of Interest


Some guidelines for designing siRNAs, e.g., herein encoded as a payload in a vector genome, have been proposed in the art. These guidelines generally recommend generating a 19-nucleotide duplexed region, symmetric 2-3 nucleotide 3′overhangs, 5-phosphate and 3-hydroxyl groups targeting a region in the gene to be silenced. Other rules that may govern siRNA sequence preference comprise, but are not limited to, (i) A/U at the 5′ end of the antisense strand; (ii) G/C at the 5′ end of the sense strand; (iii) at least five A/U residues in the 5′ terminal one-third of the antisense strand; and (iv) the absence of any GC stretch of more than 9 nucleotides in length. In accordance with such consideration, together with the specific sequence of a target gene, highly effective siRNA molecules essential for suppressing mammalian target gene expression may be readily designed.


In certain embodiments, an siRNA molecule of the present disclosure comprises a sense strand and a complementary antisense strand in which both strands are hybridized together to form a duplex structure. The antisense strand has sufficient complementarity to the mRNA sequence to direct target-specific RNAi, i.e., the siRNA. molecule has a sequence sufficient to trigger the destruction of the target mRNA by the RNAi machinery or process.


In certain embodiments, the antisense strand and target mRNA sequences have 100% complementarity. The antisense strand may be complementary to any part of the target mRNA sequence.


In certain embodiments, the antisense strand and target mRNA sequences comprise at least one mismatch. As a non-limiting example, the antisense strand and the target mRNA sequence have at least 30%, 40%, 50%, 60%, 70%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% or at least 20-30%, 20-40%, 20-50%, 20-60%, 20-70%, 20-80%, 20-90%, 20-95%, 20-99%, 30-40%, 30-50%, 30-60%, 30-70%, 30-80%, 30-90%, 30-95%, 30-99%, 40-50%, 40-60%, 40-70%, 40-80%, 40-90%, 40-95%, 40-99%, 50-60%, 50-70%, 50-80%, 50-90%, 50-95%, 50-99%, 60-70%, 60-80%, 60-90%, 60-95%, 60-99%, 70-80%, 70-90%, 70-95%, 70-99%, 80-90%, 80-95%, 80-99%, 90-95%, 90-99% or 95-99% complementary.

In certain embodiments, the siRNA molecule has a length from about 15-30, e.g., 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30 nucleotides in each strand, wherein one of the strands is sufficiently complementary to a target region.

The 3′ flanking sequence may optionally contain one or more CNNC motifs, where “N” represents any nucleotide.


Foaming the stein of a stem loop structure is a minimum of at least one payload sequence. In certain embodiments, the payload sequence comprises at least one nucleic acid sequence which is in part complementary or will hybridize to the target sequence. In certain embodiments, the payload is an siRNA molecule or fragment of an siRNA molecule.


In certain embodiments, the 5′ arm of the stein loop comprises a sense sequence.


In certain embodiments, the 3′ arm of the stem loop comprises an antisense sequence. The antisense sequence, in some instances, comprises a “G” nucleotide at the 5′ most end.


In certain embodiments, the sense sequence may reside on the 3′ arm while the antisense sequence resides on the 5′ arm of the stem of the stem loop structure.


The sense and antisense sequences may be completely complementary across a substantial portion of their length. In certain embodiments, the sense sequence and antisense sequence may be at least 70, 80, 90, 95 or 99% complementary across independently at least 50, 60, 70, 80, 85, 90, 95, or 99% of the length of the strands.


Neither the identity of the sense sequence nor the homology of th e antisense sequence need be 100% complementary to the target.


Separating the sense and antisense sequence of the stem loop structure is a loop (also known as a loop motif). The loop may be of any length, between 4-30 nucleotides, between 4-20 nucleotides, between 4-15 nucleotides, between 5-15 nucleotides, between 6-12 nucleotides, 6 nucleotides, 7, nucleotides, 8 nucleotides, 9 nucleotides, 10 nucleotides, 11 nucleotides, and/or 12 nucleotides.

In certain embodiments, the spacer is 13 nucleotides and is located between the 5′ terminus of the sense sequence and a flanking sequence. In certain embodiments, a spacer is of sufficient length to form approximately one helical turn of the sequence.


In certain embodiments, a spacer region of between 8-20, i.e., 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 nucleotides may be present between the antisense sequence and a flanking sequence.


In certain embodiments, the spacer sequence is between 10-13, i.e., 10, 11, 12 or 13 nucleotides and is located between the 3′ terminus of the antisense sequence and a flanking sequence. In certain embodiments, a spacer is of sufficient length to form approximately one helical turn of the sequence.


In certain embodiments, the modulatory polynucleotide comprises in the 5′ to 3′ direction, a 5′ flanking sequence, a. 5′ arm, a loop motif, a 3′ arm and a 3′ flanking sequence. As a non-limiting example, the 5′ arm may comprise a sense sequence and the 3′ aim comprises the antisense sequence. In another non-limiting example. the 5′ arm comprises the antisense sequence and the 3′ arm comprises the sense sequence.


In certain embodiments, the 5′ arm, payload (e.g., sense and/or antisense sequence), loop motif and/or 3′ arm sequence may be altered (e.g., substituting 1 or more nucleotides, adding nucleotides and/or deleting nucleotides). The alteration may cause a beneficial change in the function of the construct (e.g, increase knock-down of the target sequence, reduce degradation of the construct, reduce off target effect, increase efficiency of the payload, and reduce degradation of the payload).


In certain embodiments, the molecular scaffold of the modulatory polynucleotides is aligned in order to have the rate of excision of the guide strand be greater than the rate of excision of the passenger strand. The rate of excision of the guide or passenger strand may be, independently, 1%, 2%, 3%, 4%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 99% or more than 99%. As a non-limiting example, the rate of excision of the guide strand is at least 80%. As another non-limiting example, the rate of excision of the guide strand is at least 90%.


In certain embodiments, the rate of excision of the guide strand is greater than the rate of excision of the passenger strand. In one aspect, the rate of excision of the guide strand may be at least 1%, 2%, 3%, 4%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 99% or more than 99% greater than the passenger strand.


In certain embodiments, the efficiency of excision of the guide strand is at least 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 99% or more than 99%. As a non-limiting example, the efficiency of the excision of the guide strand is greater than 80%.


In certain embodiments, the efficiency of the excision of the guide strand is greater than the excision of the passenger strand from the molecular scaffold. The excision of the guide strand may be 2, 3, 4, 5, 6, 7, 8, 9, 10 or more than 10 times more efficient than the excision of the passenger strand from the molecular scaffold.


In certain embodiments, the molecular scaffold comprises a dual-function targeting modulatory polynucleotide. As used herein, a dual-function targeting modulatory polynucleotide is a polynucleotide where both the guide and passenger strands knock down the same target or the guide and passenger strands knock down different targets.


In certain embodiments, the molecular scaffold of the modulatory polynucleotides described herein comprise a 5′ flanking region, a loop region and a 3′ flanking region. Non-limiting examples of the sequences for the 5′ flanking region, loop region and the 3′ flanking region which may be used in the molecular scaffolds described herein are shown in Tables 2-4.

Any of the regions described in Tables 2-4 may be used in the molecular scaffolds described herein.


In certain embodiments, the molecular scaffold may comprise one or more linkers known in the art. The linkers may separate regions or one molecular scaffold from another. As a non-limiting example, the molecular scaffold may be polycistronic.


In certain embodiments, the modulatory polynucleotide is designed using at least one of the following properties: loop variant, seed mismatch/bulge/wobble variant, stem mismatch, loop variant and basal stem mismatch variant, seed mismatch and basal stem mismatch variant, stem mismatch and basal stem mismatch variant, seed wobble and basal stem wobble variant, or a stem sequence variant.


Introduction into Cells


The encoded siRNA molecules (e.g., siRNA duplexes) of the present disclosure may be introduced into cells by being encoded by the vector genome of an AAV particle. These AAV particles are engineered and optimized to facilitate the entry into cells that are not readily amendable to transfection/transduction. Also, some synthetic viral vectors possess an ability to integrate the shRNA into the cell genome, thereby leading to stable siRNA expression and long-term knockdown of a target gene. In this manner, viral vectors are engineered as vehicles for specific delivery while lacking the deleterious replication and/or integration features found in wild-type virus.


In certain embodiments, the encoded siRNA molecule is introduced into a cell by transfecting, infecting or transducing the cell with an AAV particle comprising nucleic acid sequences capable of producing the siRNA molecule when transcribed in the cell.

II. AAV PRODUCTION
General Viral Production Process

Viral production cells for the production of rAAV particles generally comprise mammalian cell types. However, mammalian cells present several complications to the large-scale production of rAAV particles, comprising general low yield of viral-particles-per-replication-cell as well as high risks for undesirable contamination from other mammalian biomaterials in the viral production cell. As a result, insect cells have become an alternative vehicle for large-scale production of rAAV particles,


AAV production systems using insect cells also present a range of complications. For example, high-yield production of rAAV particles often requires a lower expression of Rep78 compared to Rep52. Controlling the relative expression of Rep78 and Rep52 in insect cells thus requires carefully designed control mechanisms within the Rep operon. These control mechanisms can comprise individually engineered insect cell promoters, such as ALE1 promoters for Rep78 and Poll-I promoters for Rep52, or the division of the Rep-encoding nucleotide sequences onto independently engineered sequences or constructs. However, implementation of these control mechanisms often leads to reduced rAAV particle yield or to structurally unstable virions.


In another example, production of rAAV particles requires VP1, VP2 and VP3 proteins which assemble to form the AAV capsid. High-yield production of rAAV particles requires adjusted ratios of VP1, VP2 and VP3, which should generally be around 1:1:10, respectively, but can vary from 1-2 for VP1 and/or 1-2 for VP2, relative to 10 VP3 copies. This ratio is important for the quality of the capsid, as too much VP1 destabilizes the capsid and too little VP1 will decrease the infectivity of the vines.


Wild type AAV use a deficient splicing method to control VP1 expression; a weak start codon (ACG) with special surrounding (“Kozak” sequence) to control VP2, and a standard start codon (ATG) for VP3 expression. However, in some baculovirus systems, the mammalian splicing sequences are not always recognized and unable to properly control the production of VP1, VP2 and VP3. Consequently, neighboring nucleotides and the ACG start sequence from VP2 can be used to drive capsid protein production. Unfortunately, for most of the AAV serotypes, this method creates a capsid with a lower ratio of VP1 compared to VP2 (<1 relative to 10 VP3 copies). To more effectively control the production of VP proteins, non-canonical or start codons have been used, like TTG, GTG or CTG. However, these start codons can be considered suboptimal by those in the art relative to the wild type ATG or ACG start codons (See, WO2007046703 and WO2007148971, the content of which is incorporated herein by reference in its entirety as related to production of AAV capsid proteins, insofar as it does not conflict with the present disclosure).


In another example, production of rAAV particles using a baculovirus/SD system generally requires the widely used bacmid-based Baculovirus Expression Vector System (BEVs), which are not optimized for large-scale AAV production. Aberrant proteolytic degradation of viral proteins in the bacmid-based BEVs is an unexpected issue, precluding the reliable large-scale production of AAV capsid proteins using the baculovims/Sf9 system.


There is continued need for methods and systems which allow for effective and efficient large scale (commercial) production of rAAV particles in mammalian and insect cells.

In certain embodiments, a process of the present disclosure comprises production of viral particles in a viral production cell using a viral production system which comprises at least one viral expression construct and at least one payload construct. The at least one viral expression construct and at least one payload construct can be co-transfected (e.g. dual transfection, triple transfection) into a viral production cell. The transfection is completed using standard molecular biology techniques known and routinely performed by a person skilled in the art. The viral production cell provides the cellular machinery necessary for expression of the proteins and other biomaterials necessary for producing the AAV particles, comprising Rep proteins which replicate the payload construct and Cap proteins which assemble to form a capsid that encloses the replicated payload constructs. The resulting AAV particle is extracted from the viral production cells and processed into a pharmaceutical preparation for administration.


Once administered, the AAV particles contact a target cell and enters the cell in an endosome. The AAV particle releases from the endosome and subsequently contacts the nucleus of the target cell to deliver the payload construct. The payload construct, e.g, recombinant viral construct, is delivered to the nucleus of the target cell wherein the payload molecule encoded by the payload construct may he expressed.


In certain embodiments, the process for production of viral particles utilizes seed cultures of viral production cells that comprise one or more baculoviruses (e.g., a Baculoviral Expression Vector (BEV) or a baculovirus infected insect cell (BIIC) that has been transfected with a viral expression construct and a payload construct vector). In certain embodiments, the seed cultures are harvested, divided into aliquots and frozen, and may be used at a later time point to initiate an infection of a naïve population of production cells.


Large scale production of AAV particles may utilize a bioreactor. The use of a bioreactor allows for the precise measurement and/or control of variables that support the growth and activity of viral production cells such as mass, temperature, mixing conditions (impellor RPM or wave oscillation), CO2 concentration, O2 concentration, gas sparge rates and volumes, gas overlay rates and volumes, pH, Viable Cell Density (VCD), cell viability, cell diameter, and/or optical density (OD). In certain embodiments, the bioreactor is used for batch production in which the entire culture is harvested at an experimentally determined tune point and AAV particles are purified. In another embodiment, the bioreactor is used for continuous production in which a portion of the culture is harvested at an experimentally determined time point fir purification of AAV particles, and the remaining culture in the bioreactor is refreshed with additional growth media components.


AAV viral particles can be extracted from viral production cells in a process which comprises cell lysis, clarification, sterilization and purification. Cell lysis comprises any process that disrupts the structure of the viral production cell, thereby releasing AAV particles. In certain embodiments cell lysis may comprise thermal shock, chemical, or mechanical lysis methods. Clarification can comprise the gross purification of the mixture of lysed cells, media components, and AAV particles. In certain embodiments, clarification comprises centrifugation and/or filtration, comprising but not limited to depth end, tangential flow, and/or hollow fiber filtration.


The end result of viral production is a purified collection of AAV particles which comprise two components: (1) a payload construct (e.g. a recombinant viral genome construct) and (2) a viral capsid.


In certain embodiments, such as the embodiment presented in FIG. 1, a viral production system or process of the present disclosure comprises steps for producing baculovirus infected insect cells (BACs) using Viral Production Cells (VPC) and plasmid constructs. Viral Production Cells (VPCs) from a Cell Bank (CB) are thawed and expanded to provide a target working volume and VPC concentration, The resulting pool of VPCs is split into a Rep/Cap VPC pool and a Payload VPC pool. One or more Rep/Cap plasmid constructs (viral expression constructs) are processed into Rep/Cap Bacmid polynucleotides and transfected into the Rep/Cap VPC pool. One or more Payload plasmid constructs (payload constructs) are processed into Payload Bacmid polynucleotides and transfected into the Payload VPC pool. The two VPC pools are incubated to produce PI Rep/Cap Baculoviral Expression Vectors (BEVs) and P1 Payload BEVs. The two BEV pools are expanded into a collection of Plaques, with a single Plaque being selected for Clonal Plaque (CP) Purification (also referred to as Single Plaque Expansion). The process can comprise a single CP Purification step or can comprise multiple CP Purification steps either in series or separated by other processing steps. The one-or-more CP Purification steps provide a CP Rep/Cap BEV pool and a CP Payload BEV pool. These two BEV pools can then be stored and used for future production steps, or they can be then transfected into VPCs to produce a Rep/Cap BIIC pool and a Payload BIIC pool.


In certain embodiments, such as the embodiment presented in FIG. 2, a viral production system or process of the present disclosure comprises steps for producing AAV particles using Viral Production Cells (VPC) and baculovirus infected insect cells (BIICs).

The working volume of Viral Production Cells is seeded into a Production Bioreactor and can be further expanded to a working volume of 200-2000 L with a target VPC concentration for BIIC infection. The working volume of VPCs in the Production Bioreactor is then co-infected with Rep/Cap BIICs and Payload BACs, with a target VPC:BIIC ratio and a target BIIC:BIIC ratio. VCD infection can also utilize BEVs. The co-infected VPCs are incubated and expanded in the Production Bioreactor to produce a bulk harvest of AAV particles and VPCs.


In certain embodiments, such as the embodiment presented in FIG. 3, a viral production system or process of the present disclosure comprises steps for producing a Drug Substance by processing, clarifying and purifying a bulk harvest of AAV particles and Viral Production Cells. A bulk harvest of AAV particles and VPCs (within a Production Bioreactor) are processed through cellular disruption and lysis (e.g, chemical lysis and/or mechanical lysis), followed by nuclease treatment of the lysis pool, thereby producing a crude lysate pool. The crude lysate pool is processed through one or more filtration and clarification steps, comprising depth filtration and microfiltration to provide a clarified lysate pool. The clarified lysate pool is processed through one or more chromatography and. purification steps, comprising affinity chromatography (AFC) and ion-exchange chromatography (AEX or CEX) to provide a purified product pool. The purified product pool is then optionally processed through nanofiltration, and then through tangential flow filtration (TFF). The TFF process comprises one or more diafiltration (DF) steps and one or more ultrafiltration (UF) steps, either in series or alternating. The product pool is further processed through viral retention filtration (VRF) and another filtration step to provide a drug substance pool. The drug substance pool can be further filtered, then aliquoted into vials for storage and treatment.

In certain embodiments, the polynucleotide insert can be incorporated into the bacmid at the location of a baculoviral gene. In certain embodiments, the polynucleotide insert can be incorporated into the bacmid at the location of a non-essential baculoviral gene. In certain embodiments, the polynucleotide, insert can be incorporated into the bacmid by replacing a baculoviral gene or a portion of the baculoviral gene with the polynucleotide insert. In certain embodiments, the polynucleotide insert can be incorporated into the bacmid by replacing a baculoviral gene or a portion of the baculoviral gene with a fusion-polynucleotide which comprises the polynucleotide insert and the baculoviral gene (or portion thereof) being replaced.

Expression Control
Expression Control Regions

The viral expression constructs of the present disclosure can comprise one or more expression control region encoded by expression control sequences. In certain embodiments, the expression control sequences are for expression in a viral production cell, such as an insect cell. In certain embodiments, the expression control sequences are operably linked to a protein-coding nucleotide sequence. In certain embodiments, the expression control sequences are operably linked to a VP coding nucleotide sequence or a Rep coding nucleotide sequence.


Herein, the terms “coding nucleotide sequence”, “protein-encoding gene” or “protein-coding nucleotide sequence” refer to a nucleotide sequence that encodes or is translated into a protein product, such as VP proteins or Rep proteins. “Operably linked” means that the expression control sequence is positioned relative to the coding sequence such that it can promote the expression of the encoded gene product.


“Expression control sequence” refers to a nucleic acid sequence that regulates the expression of a nucleotide sequence to which it is operably linked. An expression control sequence is “operably linked” to a nucleotide sequence when the expression control sequence controls and regulates the transcription and/or the translation of the nucleotide sequence. Thus, an expression control sequence can comprise promoters, enhancers, untranslated regions (UIRs), internal ribosome entry sites (IRES), transcription terminators, a start codon in front of a protein-encoding gene, splicing signal for introns, and stop codons. The term “expression control sequence” is intended to comprise, at a minimum, a sequence whose presence are designed to influence expression, and can also comprise additional advantageous components. For example, leader sequences and fusion partner sequences are expression control sequences. The term can also comprise the design of the nucleic acid sequence such that undesirable, potential initiation codons in and out of frame, are removed from the sequence. It can also comprise the design of the nucleic acid sequence such that undesirable potential splice sites arc removed. It comprises sequences or polyadenylation sequences (pA) which direct the addition of a polyA tail, i.e., a string of adenine residues at the 3′-end of an mIRNA, sequences referred to as polyA sequences. It also can be designed to enhance mRNA stability. Expression control sequences which affect the transcription and translation stability, e.g., promoters, as well as sequences which effect the translation, e.g,- Kozak sequences, are known in insect cells. Expression control sequences can be of such nature as to modulate the nucleotide sequence to which it is operably linked such that lower expression levels or higher expression levels are achieved. 104341 In certain embodiments, the expression control sequence can comprise one or more promoters. Promoters can comprise, but are not limited to, baculovirus major late promoters, insect virus promoters, non-insect virus promoters, vertebrate virus promoters, nuclear gene promoters, chimeric promoters from one or more species comprising virus and non-virus elements, and/or synthetic promoters.

In certain embodiments, the promoter can comprise Rep or Cap promoters as described in US Patent Application 20110136227, the content of which is incorporated herein by reference in its entirety as related to expression promoters, insofar as it does not conflict with the present disclosure.


In certain embodiments, a viral expression construct can comprise the same promoter in all nucleotide sequences. In certain embodiments, a viral expression construct can comprise the same promoter in two or more nucleotide sequences. In certain embodiments, a viral expression construct can comprise a different promoter in two or more nucleotide sequences. In certain embodiments, a viral expression construct can comprise a different promoter in all nucleotide sequences.


In certain embodiments the viral expression construct encodes elements to improve expression in certain cell types. In a further embodiment, the expression construct may comprise polh and/or ΔIE-1 insect transcriptional promoters, CMV mammalian transcriptional promoter, and/or p10 insect specific promoters for expression of a desired gene in a mammalian or insect cell.


More than one expression control sequence can be operably linked to a given nucleotide sequence. For example, a promoter sequence, a translation initiation sequence, and a stop codon can be operably linked to a nucleotide sequence.


In certain embodiments, the viral expression construct can comprise one or more expression control sequence between protein-coding nucleotide sequences. In certain embodiments, an expression control region can comprise an IRES sequence region which comprises an IRES nucleotide sequence encoding an internal ribosome entry sight (IRES). The internal ribosome entry sight (IRES) can be selected from the group consisting or: FMDV-IRES from Foot-and-Mouth-Disease virus, EMCV-IRES from Encephalomyocarditis virus, and combinations thereof.


In certain embodiments, an expression control region can comprise a 2A sequence region which comprises a 2A nucleotide sequence encoding a viral 2A peptide. The sequence allows for co-translation of multiple polypeptides within a single open reading frame (ORF). As the ORF is translated, glycine and prolific residues with the 2A sequence prevent the formation of a normal peptide bond, which results in ribosomal “skipping” and “self-cleavage” within the polypeptide chain. The viral 2A peptide can be selected from the group consisting of: F2A from Foot-and-Mouth-Disease virus, T2A from Thosea asigna virus, E2A from Equine rhinitis A virus, P2A from porcine teschovirus-I, BmCPV2A from cytoplasmic polyhedrosis virus, BmIFV 2A from B. mori flacherie virus, and combinations thereof.

These baculoviruses may be used to infect a viral production cell for production of AAV particles or viral vector.


In certain embodiments, BEVs are produced using a Bacmid Transfection agent, such as Promega FuGENE HD, WFI water, or Thermaisher Cellfectin II Reagent. In certain embodiments, BEVs are produced and expanded in viral production cells, such as an insect cell.


In certain embodiments, the method utilizes seed cultures of viral production cells that comprise one or more BEVs, comprising baculovirus infected insect cells (BIICs). The seed BIICs have been transfected/transduced/infected with an Expression BEV which comprises a viral expression construct, and also a Payload BEV which comprises a payload construct. In certain embodiments, the seed cultures are harvested, divided into aliquots and frozen, and may be used at a later time to initiate transfection/transduction/infection of a naïve population of production cells. In certain embodiments, a bank of seed BIICs is stored at −80° C. or in LN2 vapor.


Baculoviruses are made of several essential proteins which are essential for the function and replication of the Baculovirus, such as replication proteins, envelope proteins and capsid proteins, The Baculovirus genome thus comprises several essential-gene nucleotide sequences encoding the essential proteins. As a non-limiting example, the genome can comprise an essential-gene region which comprises an essential-gene nucleotide sequence encoding an essential protein for the Baculovirus construct. The essential protein can comprise: GP64 baculovirus envelope protein, VP39 baculovirus capsid protein, or other similar essential proteins for the Baculovirus construct.


Baculovirus expression vectors (BEV) for producing AAV particles in insect cells, comprising but not limited to Spodoptera frugiperda (SD) cells, provide high titers of viral vector product. Recombinant baculovirus encoding the viral expression construct and payload. construct initiates a productive infection of viral vector replicating cells. Infectious baculovirus particles released from the primary infection secondarily infect additional cells in the culture, exponentially infecting the entire cell culture population in a number of infection cycles that is a function of the initial multiplicity of infection, see Urabe, M. et al. J Virol. 2006 February; 80(4):1874-85, the content of which is incorporated herein by reference in its entirety as related to the production and use of BEVs and viral particles, insofar as it does not conflict with the present disclosure.


Production of AAV particles with baculovirus in an insect cell system may address known baculovirus genetic and physical instability.


In certain embodiments, the production system of the present disclosure addresses baculovirus instability over multiple passages by utilizing a titerless infected-cells preservation and scale-up system. Small scale seed cultures of viral producing cells are -transfected with viral expression constructs encoding the structural and/or non-structural components of the AAV particles. Baculovirus-infected viral producing cells are harvested into aliquots that may be cryopreserved in liquid nitrogen; the aliquots retain viability and infectivity for infection of large scale viral producing cell culture Wasilko D J et al. Protein Expr Purif. 2009 June; 65(2):122-32, the content of which is incorporated herein by reference in its entirety as related to the production and use of BEVs and viral particles, insofar as it does not conflict with the present disclosure.


A genetically stable baculovirus may be used to produce a source of the one or more of the components for producing AAV particles in invertebrate cells. In certain embodiments, defective baculovirus expression vectors may be maintained episomally in insect cells. In such an embodiment the corresponding bacmid vector is engineered with replication control elements, comprising but not limited to promoters, enhancers, and/or cell-cycle regulated replication elements.


In certain embodiments, baculoviruses may be engineered with a marker for recombination into the chitinase/cathepsin locus. The chia/v-cath locus is non-essential for propagating baculovirus in tissue culture, and the V-cath (EC 3.4.22.50) is a cysteine endoprotease that is most active on Arg-Arg dipeptide containing substrates. The Arg-Arg dipeptide is present in densovirus and parvovirus capsid structural proteins but infrequently occurs in dependovirus VP1.


In certain embodiments, stable viral producing cells permissive for baculovirus infection are engineered with at least one stable integrated copy of any of the elements necessary for AAV replication and vector production comprising, but not limited to, the entire AAV genome, Rep and Cap genes, Rep genes, Cap genes, each Rep protein as a separate transcription cassette, each VP protein as a separate transcription cassette, the AAP (assembly activation protein), or at least one of the baculovirus helper genes with native or non-native promoters.


In certain embodiments, the Baculovirus expression vectors (BEV) are based on the AcMNPV baculovirus or BmNPV baculovirus BmNPV. In certain embodiments, a bacmid of the present disclosure is based on (i.e. engineered variant of) an AcMNPV bacmid such as bmon14272, vAce25ko or vAclef11KO.


In certain embodiments, the Baculovirus expression vectors (BEV) is a BEV in which the baculoviral v-cat/i gene has been partially or fully deleted (“v-cath deleted BEV”) or mutated. In certain embodiments, the BEVs lack the v-cath gene or comprise a mutationally inactivated version of the v-cath gene. In certain embodiments, the BEVs lack the v-cath gene. In certain embodiments, the BEVs comprise a mutationally inactivated version of the v-cath gene.


Viral production bacmids of the present disclosure can comprise deletion of certain baculoviral genes or loci.


The baculovirus/Sf9 system is a cGMP compatible and scalable manufacturing platform established for rAAV production. Baculoviral inoculum is a critical raw material for this manufacturing process and can have a significant impact on process yields and product quality. However, as with any other biological-based production processes, there is a large potential for batch-to-batch variability in the production of baculoviral inoculum. Each hank baculoviral inoculum requires extensive analytical characterization and optimized bioreactor production parameters to be used optimally in rAAV production (which adds time and cost for large-scale manufacturing). It is therefore advantageous to produce large banks of baculoviral inoculum, as these large banks allow for consistent and repeatable production of rAAV in large-scale bioreactors across multiple manufacturing campaigns from the same baculoviral inoculum bank.


In certain embodiments, baculoviral inoculum banks can be produced using small-scale shake flasks, such as 3L or 5L shake flasks. However, this process is generally limited in the maximum cell density of the BIIC cells which can be produced, and thus requires centrifugation to concentrate resulting cells into a workable concentration. This correspondingly limits the volume (i.e. quantity) of the baculoviral inoculum bank (˜600 mL) which can be produced and stored using this method. This process also presents sterility concerns due to open operation.


In certain embodiments, baculoviral inoculum banks can be produced using bioreactors, such as 20-50 L bioreactors. However, this process is also generally limited in the maximum cell density of the BIIC cells which can be produced, and thus requires significant processing through Tangential Flow Filtration (TFF) and/or centrifugation to concentrate resulting cells into a workable concentration (with 3 L of culture material being required to produce about 600 mL of concentrated BIIC formulation, corresponding with a 15-25% yield). This correspondingly limits the volume (i.e. quantity) of the baculoviral inoculum bank (˜3000 mL) which can be produced and stored using this method. This process also presents sterility concerns due to open operation.


In certain embodiments, perfusion technology can be used in the production of baculoviral inoculum banks. Perfusion systems are fluid circulation systems which use combinations of pumps, filters and screens to retain cells inside a bioreactor while continually removing cell waste products and replacing media depleted of nutrients by cell metabolism. In certain embodiments, the perfusion system is an alternating tangential flow (ATF) perfusion system. in certain embodiments, a perfusion system can be used in coordination with bioreactors to manage and cycle cell culture media within a bioreactor during the production of Baculovirus Infected Insect Cells (BACs). In certain embodiments, a perfusion system can be used to support the production of high quality BIIC banks having an unexpectedly high cell density at large-scale. In certain embodiments, a perfusion system can be used to provide an infection-cell-to-product-cell yield of greater than 70% (e.g. 75-80%, 80-85%, 85-90%, 90-95% or 95-100%). In certain embodiments, a perfusion system can be used to perform a media switch within the bioreactor, such as the replacements of a cell culture media with a cryopreservation media which allows for BIIC cells to be frozen and preserved.

Viral production can comprise clarification steps at any point in the viral production process. Clarification steps may comprise, but are not limited to, centrifugation and filtration. During clarification, centrifugation may be carried out at low speeds to remove larger debris only. Similarly, filtration may be carried out using filters with larger pore sizes so that only larger debris is removed.


Purification generally refers to the final steps taken in the purification and concentration of viral particles from cell lysates by removing smaller debris from a clarified lysis harvest in preparing a final Pooled Drug Substance. Viral production can comprise purification steps at any point in the viral production process. Purification steps may comprise, but are not limited to, filtration and chromatography. Filtration may be carried out using filters with smaller pore sizes to remove smaller debris from the product or with larger pore sizes to retain larger debris from the product. Filtration may be used to alter the concentration and/or contents of a viral production pool or stream. Chromatography may be carried out to selectively separate target particles from a pool of impurities.


Large-scale production of high-concentration AAV formulations is complicated by the tendency for high concentrations of AAV particles to aggregate or agglomerate.

In certain embodiments, nanofiltration is used to remove aggregated clumps of viral particles.


In certain embodiments, one or more tangential flow filtration (TFF) (also known as cross-flow filtration) steps may be used during clarification and purification, Tangential flow filtration is a form of membrane filtration in which a feed stream (which comprises the target agent/particle to be clarified and concentrated) flows from a feed tank into a filtration module or cartridge, Within the TFF filtration module, the feed stream passes parallel to a membrane surface, such that one portion of the stream passes through the membrane (permeate/filtrate) while the remainder of the stream (retentate) is recirculated back through the filtration system and into the feed tank.


In certain embodiments, the TFF filtration module can be a flat plate module (stacked planar cassette), a spiral wound module (spiral-wound membrane layers), or a hollow fiber module (bundle of membrane tubes). Examples of TFF systems for use in the present disclosure comprise, but are not limited to: Spectrum mPES Hollow Fiber TFF system (0.5 mm fiber ID, 100 kDA MWCO) or Millipore Ultracel PLCTK system with Pellicon-3 cassette (0.57 m2, 30 kDA INIWCO).


New buffer materials can be added to the TFF feed tank as the feed stream is circulated through the TFF filtration system. In certain embodiments, buffer materials can be fully replenished as the flow stream circulates through the TFF filtration system. In this embodiment, buffer material is added to the stream in equal amounts to the buffer material lost in the permeate, resulting in a constant concentration. In certain embodiments, buffer materials can be reduced as the flow stream circulates through the filtration system. In this embodiment, a reduced amount of buffer material is added to the stream relative to the buffer material lost in the permeate, resulting in an increased concentration. In certain embodiments, buffer materials can be replaced as the flow stream circulates through the filtration system. In this embodiment, the buffer added to stream is different from buffer materials lost in the permeate, resulting in an eventual replacement of buffer material in the stream. TFF systems of the present disclosure can be pre-rinsed, packed, equilibrated, flushed, processed, eluted, washed or cleaned with formulations known to those in the art, comprising AAV pharmaceutical, processing and storage formulations of the present disclosure.

In the concentration stage, a reduced amount of buffer material is replaced as the stream circulates through the filtration system (relative to the amount of buffer material lost as permeate). The failure to completely replace all of the buffer material lost in the permeate results in an increased concentration of viral particles within the filtration stream. In certain embodiments, an increased amount of buffer material is replaced as the stream circulates through the filtration system. The incorporation of excess buffer material relative to the amount of buffer material lost in the permeate results in a decreased concentration of viral particles within the filtration stream.


In certain embodiments, TFF processing can comprise one or more diafiltration (DF) stages. The diafiltration stage comprises replacement of a first buffer material (such as a high salt material) within a second buffer material (such a low-salt or zero-salt material). In this embodiment, a second buffer is added to flow stream which is different from a first buffer material lost in the permeate, resulting in an eventual replacement of buffer material in the stream.


In certain embodiments, TFF processing can comprise multiple stages in series. In certain embodiments, a TFF processing process can comprise an ultrafiltration (UF) concentration stage followed by a diafiltration stage (DF). In certain embodiments, a TFF processing can comprise a diafiltration stage followed by an ultrafiltration concentration stage. In certain embodiments, a TFF processing can comprise a first diafiltration stage, followed by an ultrafiltration concentration stage, followed by a second diafiltration stage. In certain embodiments, a TFF processing can comprise a first diafiltration stage which incorporates a high-salt-low-sugar buffer material into the flow stream, followed by an ultrafiltration/concentration stage which results in a high concentration of the viral material in the flow stream, followed by a second diafiltration stage which incorporates a low-salt-high-sugar or zero-salt-high-sugar buffer material into the flow stream. In certain embodiments, the salt can he sodium chloride, sodium phosphate, potassium chloride, potassium phosphate, or a combination thereof. In certain embodiments, the sugar can be sucrose, such as a 5% w/v sucrose mixture or a 7% w/v sucrose mixture.

In certain embodiments, the high-sucrose formulation buffer comprises between 6-8% w/v of a sugar or sugar substitute and between 90-100 mM of an alkali chloride salt. In certain embodiments, the high-sucrose formulation buffer comprises 7% w/v of sucrose and between 90-100 mM sodium chloride. In certain embodiments, the high-sucrose formulation buffer comprises 7% w/v of sucrose. 10 mM Sodium Phosphate, between 95-100 sodium chloride, and 0.001% (w/v) Poloxamer 188. In certain embodiments, the formulation diafiltration step is the final diafiltration step in the one or more TFF steps. In certain embodiments, the formulation diafiltration step is the only diafiltration step in the one or more TFF steps.


In certain embodiments, TFF processing can comprise multiple stages which occur contemporaneously. As a non-limiting example, a TFF clarification process can comprise an ultrafiltration stage which occurs contemporaneously with a concentration stage.

III. COMPOSITIOSN AND FORMULATIONS
General

Gene therapy drug products (such as rAAV particles) are challenging to incorporate into composition and formulations due to their limited stability in the liquid state and a high propensity for large-scale aggregation at low concentrations. Gene therapy drug products are often delivered directly to treatment areas (comprising CNS tissue); which requires that excipients and formulation parameters be compatible with tissue function, microenvironment, and volume restrictions.


According to the present disclosure. AAV particles may he prepared as, or comprised in, pharmaceutical compositions. It will be understood that such compositions necessarily comprise one or more active ingredients and, most often, one or more pharmaceutically acceptable excipients.


Relative amounts of the active ingredient (e.g. AAV particle), a pharmaceutically acceptable excipient, and/or any additional ingredients in a pharmaceutical composition in accordance with the present disclosure may vary, depending upon the identity, size, and/or condition of the subject being treated and further depending upon the route by which the composition is to be administered. For example, the composition may comprise between 0.1% and 99% v/w) of the active ingredient. By way of example, the composition may comprise between 0.1% and 100%, e.g., between .5 and 50%, between 1-30%, between 5-80%, or at least 80% (w/w) active inuedient.


In certain embodiments, the AAV particle pharmaceutical compositions described herein may comprise at least one payload of the present disclosure. As a non-limiting example, the pharmaceutical compositions may contain an AAV particle with 1, 2, 3, 4 or 5 payloads.


Although the descriptions of pharmaceutical compositions provided herein are principally directed to pharmaceutical compositions which are suitable for administration to humans, it will be understood by the skilled artisan that such compositions are generally suitable for administration to any other animal, e.g., to non-human animals, e.g. non-human mammals. Modification of pharmaceutical compositions suitable for administration to humans in order to render the compositions suitable for administration to various animals is well understood, and the ordinarily skilled veterinary pharmacologist can design and/or perform such modification with merely ordinary, if any, experimentation. Subjects to which administration of the pharmaceutical compositions is contemplated comprise, but are not limited to, humans and; or other primates; mammals, comprising commercially relevant mammals such as cattle, pigs, horses, sheep, cats, dogs, mice, rats, birds, comprising commercially relevant birds such as poultry, chickens, ducks, geese, and/or turkeys.


In certain embodiments, compositions are administered to humans, human patient or subjects.


Formulations of the present disclosure can comprise, without limitation, saline, liposomes, lipid nanoparticles, polymers, peptides, proteins, cells transfected with AAV particles (e.g., for transfer or transplantation into a subject) and combinations thereof.


Formulations of the pharmaceutical compositions described herein may be prepared by any method known or hereafter developed in the art of pharmacology. As used herein the term “pharmaceutical composition” refers to compositions comprising at least one active ingredient and optionally one or more pharmaceutically acceptable excipients.

Injectable Formulations

Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing agents, wetting agents, and/or suspending agents. Sterile injectable preparations may be sterile injectable solutions, suspensions, and/or emulsions in nontoxic parenterally acceptable diluents and/or solvents, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, U.S.P., and isotonic sodium chloride solution. Sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose, any bland fixed oil can he employed comprising synthetic mono- or diglycerides. Fatty acids such as oleic acid can be used in the preparation of injectables.


Injectable formulations may be sterilized, for example, by filtration through a bacterial-retaining filter, and/or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.


In order to prolong the effect of active ingredients, it is often desirable to slow the absorption of active ingredients from subcutaneous or intramuscular injections. This may be accomplished by the use of liquid suspensions of crystalline or amorphous material with poor water solubility. The rate of absorption of active ingredients depends upon the rate of dissolution which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle, Injectable depot forms are made by forming microencapsulated matrices of the drug in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers comprise poly(orthoesters) and poly(anhydrides). Depot injectable formulations are prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissues.


Depot Formulations

In certain embodiments of the present disclosure, AAV particle formulations of the present disclosure are formulated in depots for extended release. Generally, specific organs or tissues (“target tissues”) are targeted for administration.


In certain embodiments of the disclosure, pharmaceutical compositions, AAV particle formulations of the present disclosure are spatially retained within or proximal to target tissues. Provided are methods of providing pharmaceutical compositions, AAV particle formulations, to target tissues of mammalian subjects by contacting target tissues (which comprise one or more target cells) with pharmaceutical compositions, AAV particle formulations, under conditions such that they are substantially retained in target tissues, meaning that at least 10, 20, 30, 40, 50, 60, 70, 80, 85, 90, 95, 96, 97, 98, 99, 99.9, 99.99 or greater than 99.99% of the composition is retained in the target tissues. Advantageously, retention is determined by measuring the amount of pharmaceutical compositions, AAV particle formulations, that enter one or more target cells. For example, at least 1%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, 99.9%, 99.99% or greater than 99.99% of pharmaceutical compositions, AAV particle formulations, administered to subjects are present intracellularly at a period of time following administration.

The specific therapeutically effective, prophylactically effective, or appropriate diagnostic dose level for any particular individual will depend upon a variety of factors comprising the disorder being treated and the severity of the disorder; the activity of the specific payload employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific AAV particle employed; the duration of the treatment; drugs used in combination or coincidental with the specific AAV particle employed; and like factors well known in the medical arts. In certain embodiments, delivery of the formulated AAV particles of the present disclosure results in minimal serious adverse events (SAEs) as a result of the delivery of the formulated AAV particles.


Traditionally, in order to achieve a sufficiently high quantity of a standard therapeutic (ensuring long lasting therapeutic effects), many therapies are delivered by repeated or extended administration, e.g. by multiple injections or long infusions. However, these extended dosing regimens are not well suited for certain AAV gene therapy modalities, such as those driven by single dose paradigms. Extended AAV dosing regimens can be particularly problematic in the treatment of CNS diseases due to limited volumetric space for formulation fluids, strinaent limitations on excipient quantity and potency, impact of ionic particles on CNS micro-environment, and surgical and clinical complications related to extended CNS treatments. Novel formulations of gene therapy modalities are necessary to achieve sufficiently high concentrations of therapeutic agents within the formulation.


In certain embodiments, formulated AAV particle pharmaceutical compositions in accordance with the present disclosure may be administered at dosage levels sufficient to deliver from about 0.0001 mg/kg to about 100 mg/kg, from about 0.001 mg/kg to about 0.05 ma/kg, from about 0.005 mg/kg to about 0.05 mg/kg, from about 0.001 mg/kg to about 0.005 mg/kg, from about 0.05 mg/kg to about 0.5 mg/kg, from about 0.01 mg/kg to about 50 mg/kg, from about 0.1 mg/kg to about 40 mg/kg, from about 0.5 mg/kg to about 30 mg/kg, from about 0.01 mg/kg to about 10 mg/kg, from about 0.1 mg/kg to about 10 mg/kg, or from about 1 mg/kg to about 25 mg/kg, of subject body weight per day, one or more times a day, to obtain the desired therapeutic, diagnostic, or prophylactic, effect. It will be understood that the above dosing concentrations may be converted to vg or viral genomes per kg or into total viral genomes administered by one of skill in the art.


In certain embodiments, formulated AAV particle pharmaceutical compositions in accordance with the present disclosure may be administered at about 10 to about 600 μl/site, 50 to about 500 μl/site, 100 to about 400 μl/site, 120 to about 300 μl/site, 140 to about 200 μl/site, about 160 μl/site.

In certain embodiments, the selection of subjects for administration of the AAV particle described herein and/or the effectiveness of the dose, route of administration and/or volume of administration may be evaluated using imaging of the perivascular spaces (PVS) which are also known as Virchow-Robin spaces. PVS surround the arterioles and venules as they perforate brain parenchyma and are filled with cerebrospinal fluid (CSF)linterstitial fluid. PVS are common in the midbrain, basal ganglia, and centnim semiovale. While not wishing to be bound by theory, PVS may play a role in the normal clearance of metabolites and have been associated with worse cognition and several disease states comprising Parkinson's disease. PVS are usually are normal in size but they can increase in size in a number of disease states. Potter et al. (Cerehrovasc Dis. 2015 January; 39(4): 224-231; the contents of which are herein incorporated by reference in its entirety) developed a grading method where they studied a frill range of PVS and rated basal ganglia, centrum semiovale and midbrain PVS. They used the frequency and range of PVS used by Mac and Luilich et al. (J Neurol Neurosurg Psychiatry. 2004 November;75(11):1519-23; the contents of which are herein incorporated by reference in its entirety) and Potter et al. gave 5 ratings to basal ganglia and centrum semiovale PVS: 0 (none), 1 (1-10), 2 (11-20), 3 (21-40) and 4 (>40) and 2 ratings to midbrain PVS: 0 (non-visible) or 1 (visible). The user guide for the rating system by Potter et al. can be found at: www.shirc.ed.ac.uk/documents/epvs-rating-scale-user-guide.pdf

Measurement and Analysis

Expression of payloads or the downregulating effect of such payloads from viral genomes may be determined using various methods known in the art such as, but not limited to immunochemistry (e.g., II-IC), in situ hybridization (ISM, enzyme-linked immunosorbent assay (ELISA), affinity ELISA, ELISPOT, flow cytometry, immunocytology, surface plasmon resonance analysis, kinetic exclusion assay, liquid chromatography-mass spectrometry (LCMS), high-performance liquid chromatography (HPLC), BCA assay, immunoelectrophoresis, Western blot, SDS-PAGE, protein immunoprecipitation, and/or PCR.


Bioavailability

In certain embodiments, AAV particles formulated into a composition with a delivery agent as described herein can exhibit an increase in bioavailability as compared to a composition lacking a delivery agent as described herein. As used herein, the term “bioavailability” refers to the systemic availability of a given amount of AAV particle or expressed payload administered to a mammal. Bioavailability can be assessed by measuring the area under the curve (AUC) or the maximum serum or plasma concentration (Cmax) of the composition following. AUC is a determination of the area under the curve plotting the serum or plasma concentration of a compound (e.g., AAV particles or expressed payloads) along the ordinate (Y-axis) against time along the abscissa (X-axis). Generally, the AUC for a particular compound can be calculated using methods known to those of ordinary skill in the art and as described in G. S. Banker, Modern Pharmaceutics, Drugs and the Pharmaceutical Sciences, v. 72, Marcel Dekker, New York, Inc., 1996, the contents of which are herein incorporated by reference in its entirety.


The Cmax value is the maximum concentration of the AAV particle or expressed payload achieved in the serum or plasma of a mammal following administration of the AAV particle to the mammal. The Cmax value of can be measured using methods known to those of ordinary skill in the art. The phrases “increasing bioavailability” or “improving the pharmacokinetics,” as used herein mean that the systemic availability of a first AAV particle or expressed payload, measured as AUC, Cmax, or Cmin in a mammal is greater, when co-administered with a delivery agent as described herein, than when such co-administration does not take place. In certain embodiments, the bioavailability can increase by at least about 2%, at least about 5%, at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45%, at least about 50%, at least about 55%, at least about 60%, at least about 65%, at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 95%, or about 100%.


Therapeutic Window

As used herein “therapeutic window” refers to the range of plasma concentrations, or the range of levels of therapeutically active substance at the site of action, with a high probability of eliciting a therapeutic effect. In certain embodiments, the therapeutic window of the AAV particle formulations as described herein can increase by at least about 2%, at least about 5%, at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45%, at least about 50%, at least about 55%, at least about 60%, at least about 65%, at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 95%, or about 100%.


Volume of Distribution

As used herein, he term “volume of distribution”refers to the fluid volume that would be required to contain the total amount of the drug in the body at the same concentration as in the blood or plasma: Vdist equals the amount of drug in the body/concentration of drug in blood or plasma. For example, for a 10 mg dose and a plasma concentration of 10 mg/L, the volume of distribution would be 1 liter. The volume of distribution reflects the extent to which the drug is present in the extravascular tissue. A large volume of distribution reflects the tendency of a compound to bind to the tissue components compared with plasma protein binding. In a clinical setting, Vdist can be used to determine a loading dose to achieve a steady state concentration. In certain embodiments, the volume of distribution of the AAV particle formulations as described herein can decrease at least about 2%, at least about 5%, at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45%, at least about 50%, at least about 55%, at least about 60%, at least about 65%, at least about 70%.


Biologic Effect

In certain embodiments, the biological effect of the AAV particle formulations delivered to the animals may be categorized by analyzing the payload expression in the animals. The payload expression may be determined from analyzing a biological sample collected from a mammal administered the AAV particle formulations of the present disclosure. For example, a protein expression of 50-200 pg/ml for the protein encoded by the AAV particles delivered to the mammal may be seen as a therapeutically effective amount of protein in the mammal.

Therapeutic Indications
Parkinson s Disease

Parkinson's Disease (PD) is a progressive disorder of the nervous system affecting especially the substantia nigra of the brain. PD develops are a result of the loss of dopamine producing brain cells. Typical early syinptoms of PD comprise shaking or trembling of a limb, e.g, hands, arms, legs, feet and face. Additional characteristic symptoms are stiffness of the limbs and torso, slow movement or an inability to move, impaired balance and coordination, cognitional changes, and psychiatric conditions e.g., depression and visual hallucinations. PD has both familial and idiopathic forms and it is suggestion to be involved with genetic and environmental causes. PD affects more than 4 million people worldwide. In the US, approximately 60,000 cases are identified annually. Generally, PD begins at the age of 50 or older. An early-onset form of the condition begins at age younger than 50, and juvenile-onset PD begins before age of 20.


Death of dopamine producing brain cells related to PD has been associated with aggregation, deposition and dysfunction of alpha-synuclein protein (see, e.g. Marques and Outeiro, 2012, Cell Death Dis. 3:e350, Jenner, 1989, J Neurol Neurosurg Psychiatry. Special Supplement, 22-28, and references therein). Studies have suggested that alpha-synuclein has a role in presynaptic signaling, membrane trafficking and regulation of dopamine release and transport. Alpha-synuclein aggregates, e,g. in forms of oligomers, have been suggested to he species responsible for neuronal dysfunction and death. Mutations of the alpha-synuclein gene (SNCA) have been identified in the familial forms of PD, but also enviromnental factors, e.g. neurotoxin affect alpha-synuclein aggregation. Other suggested causes of brain cell death in PD are dysfunction of proteosomal and lysosomal systems, reduced mitochondrial activity.


PD is related to other diseases related to alpha-synuclein aggregation, referred to as “synucleinopathies.” Such diseases comprise, but are not limited to, Parkinson's Disease Dementia (PDD), multiple system atrophy (MSA), dementia with Lewy bodies, juvenile-onset generalized neuroaxonal dystrophy (Hallervorden-Spatz disease), pure autonomic failure (PAF), neurodegeneration with brain iron accumulation type-1 (NBIA-1) and combined Alzheimer's and Parkinson's disease.


As of today, no cure or prevention therapy for PD has been identified. A variety of drug therapies available provide relief to the symptoms. Non-limiting examples of symptomatic medical treatments comprise carbidopa and levodopa combination reducing stiffness and slow movement, and anticholinergics to reduce trembling and stiffness. Other optional therapies comprise e.g. deep brain stimulation and surgery. There remains a need for therapy affecting the underlying pathophysiology. For example, antibodies targeting alpha-synuclein protein, or other proteins relevant for brain cell death in PD, may be used to prevent and/or treat PD.


In certain embodiments, methods of the present disclosure may be used to treat subjects suffering from PD and other synucleinopathies. In certain embodiments, methods of the present disclosure may be used to treat subjects suspected of developing PD and other synucleinopathies.


AAV particles, pharmaceutical formulations and methods of using the viral particles described in the present disclosure may be used to prevent, manage and/or treat PD.


Spinal Muscular Atrophy

Spinal muscular atrophy (SMA) is a hereditary disease-causing weakness and wasting of the voluntary muscles in the arms and legs of infants and children. SMA is associated with abnormalities in the protein production of the survival motor neuron gene 1 (SMN1). Lack of the protein affects degeneration and death of lower motor neurons. Typical symptoms comprise floppy limbs and trunk, feeble movement of the arms and legs, difficulties in swallowing and eating, and impaired breathing. SMA is the most common genetic disorder leading to death of children under 2 years of age. SMA affects one in 6,000 to 10,000 people.


As of today, there is no cure for SMA. Therapies available are aimed at management of the symptoms and prevention of additional complications. Such therapies are associated e.g. with cardiology, movement management, respiratory care and mental health. There remains a need for therapy affecting the underlying pathophysiology of SMA and related diseases and ailments.


In certain embodiments, the AAV particles and methods of the present disclosure may be used to treat subjects suffering from SMA and related diseases and ailments. In certain embodiments, methods of the present disclosure may be used to treat subjects suspected of developing SMA or related diseases and ailments.

Alzheimer's Disease

Alzheimer's Disease (AD) is a debilitating neurodegenerative disease and the most common form of dementia affecting the memory, thinking and behavior. Typical early symptom is difficulty of remembering newly learned information. As the disease advances, symptoms comprise disorientation, changes in sleep, changes in mood and behavior, confusion, unfound suspicions and eventually difficulty to speak, swallow and walk. AD currently afflicts more than 35 million people worldwide, with that number expected to double in coming decades.


As of today, no cure or prevention therapy for AD has been identified. Drug therapy to treat memory loss, behavioral changes and sleep changes, and to slow down the progression of AD are available. However, these symptomatic treatments do not address the underlying pathophysiology.


In certain embodiments, methods of the present disclosure may be used to treat subjects suffering from AD and related diseases and ailments. In certain embodiments, methods of the present disclosure may be used as a therapy for to treat subjects suspected of developing AD or related diseases and ailments.


AAV particles, pharmaceutical formulations and methods of using the viral particles described in the present disclosure may be used to prevent, manage and/or treat AD and related diseases and ailments.


Amyotrophic Lateral Sclerosis

Amyotrophic Lateral Sclerosis (ALS), also known as Lou Gehrig's disease or classical motor neuron disease, is a rapidly progressive and fatal neurological disease. ALS is associated with cell degeneration and death of the upper and lower motor neurons, leading to enablement of muscle movement, weakening, wasting and loss of control over voluntary muscle movement. Early symptoms comprise muscle weakness of hands, legs and swallowing muscles, eventually progressing to inability to breathe due to diaphragm failure. According to Centers for Disease Control and Prevention (CDC), ALS affects an estimated 12,000-15,000 individuals in the US. About 5-10% of cases are familial.


ALS, as other non-infectious neurodegenerative diseases, has been characterized by presence of misfolded proteins. Familial ALS has been associated with mutations of TAR DNA-binding protein 43 (TDP-43) and RNA-binding protein FUS/TLS. Some proteins have been identified to slow down progression of ALS, such as, but not limited, to growth factors, e.g. insulin-like growth factor 1 (IGF-1), glial cell line-derived growth factor, brain-derived growth factor, vascular endothelial growth factor and ciliary neurotrophic factor, or growth factors promoting muscle growth, e.g. myostatin.


As of today, there is no prevention or cure for ALS. FDA approved drug niluzole has been approved to prolong the life but does not have an effect on symptoms. Additionally, drugs and medical devices are available to tolerate pain and attacks associated with ALS. There remains a need for therapy affecting the underlying pathophysiology.


In certain embodiments, methods of the present disclosure may be used to treat subjects suffering from ALS and related diseases and ailments. In certain embodiments, methods of the present disclosure may be used to treat subjects suspected of developing ALS or related diseases and ailments.


AAV particles, pharmaceutical formulations and methods of using the viral particles described in the present disclosure may be used to prevent, manage and/or treat ALS and related diseases and ailments.


Huntington's Disease

Huntington's disease (HD) is a rare, inherited disorder causing degeneration of neurons in the motor control region of the brain, as well as other areas. Typical symptoms of the disease comprise uncontrolled movements (chorea), abnormal postures, impaired coordination, slurred speech and difficulty of feeding and swallowing accompanied by changes in behavior, judgment and cognition. HD is caused by mutations in the gene associated with the huntingtin (HTT) protein. The mutation causes the (CAG) blocks of DNA to repeat abnormally many times. HD affects approximately 30,000 individuals in the US.


HD is characterized by mutations of the huntingtin (HTT) protein with abnormal expansions of polyglutamine tracts, e.g. expansion of the length of glutamine residues encoded by CAG repeats. The expansion threshold for occurrence of the disease is considered to be approximately 35-40 residues. HD is also associated with beta sheet rich aggregates in striatal neurons formed by N-terminal region of HTT. The expansions and aggregates lead to gradual loss of neurons as HD progresses. Additionally, the cell death in FED is associated with death receptor 6 (DR6) which is known to induce apoptosis.


As of today, there is no therapy to cure, or prevent the progression of the disease. Drug therapies available are aimed at management of the symptoms. For example, FDA has approved tetrabenezine to be prescribed for prevention of chorea. Additionally, e.g. antipsychotic drugs may help to control delusions, hallucinations and violent outbursts. There remains a need for therapy affecting the underlying, pathophysiology, such as antibody therapies targeting the HTT protein, DR6 protein, and/or other HD associated proteins.


In certain embodiments, methods of the present disclosure may be used to treat subjects suffering from HD and related diseases and ailments. In certain embodiments, methods of the present disclosure may he used to treat subjects suspected of developing HD or related diseases and ailments.


AAV particles, pharmaceutical formulations and methods of using the viral particles described in the present disclosure may be used to prevent, manage and/or treat HD and related diseases and ailments.

The term “homologous” necessarily refers to a comparison between at least two sequences (polynucleotide or polypeptide sequences). In accordance with the present disclosure, two polynucleotide sequences are considered to be homologous if the polypeptides they encode are at least about 50%, 60%, 70%, 80%, 90%, 95%, or even 99% for at least one stretch of at least about 20 amino acids. In certain embodiments, homologous polynucleotide sequences are characterized by the ability to encode a stretch of at least 4-5 uniquely specified amino acids.

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. 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; the contents of which are each incorporated herein by reference in their entireties, insofar as they do not conflict with the present disclosure. 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 comprise, but are not limited to those disclosed in Carillo, H., and Lipman, D., SIAM J Applied Math., 48:1073 (1988); the contents of which are each incorporated herein by reference in their entireties, insofar as they does not conflict with the present disclosure. Techniques for determining identity are codified in publicly available computer programs.

The expression product can be an RNA. transcribed from the gene (e.g., an mRNA) or a polypeptide translated from an mRNA transcribed from the gene. Typically, a reduction in the level of an mRNA results in a reduction in the level of a polypeptide translated therefrom. The level of expression may be determined using standard techniques for measuring mRNA or protein.
