[0003] The Sequence Listing submitted 1 November 2023 as an XML file named “22-2060-WO- Sequence_Listing’‘, created on 31 October 2023 and having a size of 289 kilobytes is hereby incorporated by reference pursuant to 37 C.F.R. § 1.52(e)(5).IV. BACKGROUND

[0004] Monomeric IgM is the first antibody to emerge as the B cell antigen receptor (BCR) on the surface of B cells followed by secreted pentameric IgM from plasma cells. Class switching upon B cell activation generates different isotypes or subtypes of IgG, which constitute the most abundant, secreted class of antibodies (Engels N, et al. (2018) Immunol Rev. 283: 150-160). Due to the highly diverse BCR repertoire, recognition of self-antigens can sometimes lead to the generation of harmful IgG and IgM autoantibodies leading to autoimmune disease (Suurmond J, et al. (2015) J Clin Invest. 125:2194-2202). Similarly, antibodies directed against human leukocyte antigens (HLAs) expressed on the surface of cells in a transplanted organ can lead to rejection (Choi AY, et al. (2021) Front Immunol. 12:694-763). . Further, while beneficial in the context of immunity against pathogens such as viruses, antibodies against viral vectors such as recombinant adeno-associated viruses (AAV) can preclude administration of gene therapies in prospective patients (Earley J, et al. (2023) Trends Biotechnol. 41 :836-845)). Another pathophysiological manifestation of autoantibodies in the context of autoimmune disease, organ transplantation or gene therapies is the activation of the complement cascade and lytic components thereof, which can lead to significant tissue damage (Goldberg BS, et al. (2020) Immunol Cell Biol. 98:305-317; Grafals M, et al. (2019) Front Immunol. 10:2380; West C, et al. (2023) Hum Gene Ther. 34:554-566; Smith CJ, et al. (2022) Front Immunol. 13:999-1021). Thus, understanding and manipulating IgG and IgM levels can have profound implications in the development of therapeutic modalities with broad clinical impact.

[0005] To this end, a wide range of approaches including plasmapheresis, B cell targeting agents, complement inhibitors, neonatal Fc receptor (FcRn) blocking agents and IgG degrading enzymes are being explored to modulate humoral immunity7in autoimmune disease, organ transplant and gene therapy applications (Choi AY, et al. (2021) Front Immunol. 12:694-763; Lee DSW, et al. (2020) Nature Reviews Drug Discov. 20: 179-199; Zelek WM, et al. (2019) Mol Immunol. 114:341-352; Corti M, et al. (2014) Mol Ther Methods Clin Dev. 1 : 14033; Elmore ZC, et al. (2020) JCI Insight. 5(19):el39881; Leborgne C, et al. (2020) Nature Med. 26:1096-1101). Despite this spectrum of agents, strategies that directly address pathogenic IgM and IgG antibodies, which are key players in initiating immune dysfunction, are lacking.

[0006] Thus, there remains an urgent need to generate and characterize antibody-cleaving enzymes, and to develop therapeutics based on those antibody-cleaving enzymes.V. BRIEF DESCRIPTION OF THE FIGURES

In an aspect, the identification can be performed by a person different from the person making the diagnosis. In an aspect, the administration can be performed by one who performed the diagnosis.

[0043] As discussed herein, humoral immunity is mediated by circulating proteins called antibodies, which are produced by B lymphocytes. Antibodies exist either as membrane-bound antibodies on the surface of B lymphocytes that function as receptors for the antigen or as secreted antibodies that reside in the circulation, tissues, and mucosal sites to neutralize toxins, prevent the entry and spread of pathogens, and eliminate microbes. The activation of B lymphocytes is initiated by the specific recognition of antigens by the surface Ig receptors of these cells. Activation leads to proliferation of antigen-specific cells and their differentiation in cooperation with Th cells, generating memory B lymphocytes and antibody-secreting plasma cells. The type and amount of antibodies produced vary according to the antigen driving the immune response, the involvement of T lymphocytes, a prior history of antigen exposure, and the site where activation occurs. Antibody responses to protein antigens require that the specifically recognized antigen is internalized by B lymphocytes and that a peptide fragment of it is presented to CD4+ helper T lymphocytes that subsequently activate these B lymphocytes. Because of the involvement of helper T lymphocytes, this type of response is called ‘T-dependent antibody response' (TDAR). In contrast, antibody responses to multivalent nonproteinic antigens with repeating determinants, such as polysaccharides, some lipids, and nucleic acids, do not involve antigen-specific helper T lymphocytes and are called ‘T-independent antibody responses.’ In TDARs, plasma cells or their precursors migrate from germinal centers in the peripheral lymphoid organs, where they are produced, to the bone marrow, where they live for many years and ensure specific protection against microbes for long periods of time.

[0044] As used herein, ‘’immune response” refers to the body’s response to foreign agents and infections organisms and includes (i) the body’s innate or non-specific immune system and (ii) the body's adaptive or specific immune system (including B cells, cytotoxic T cells, and helper T cells).

[0045] As used herein, ‘'primary and secondary antibody responses” to protein antigens differ qualitatively and quantitatively. Primary responses result from the activation of naive B lymphocytes that have not been previously stimulated by the antigen, whereas a secondary' immune response is elicited when the same antigen stimulates antigen-specific memory B lymphocytes. In secondary responses as compared to primary responses, antibody production is greater and peak antibody levels attained more rapidly (approximately 2-3 vs. 7 days), the main isotype is IgG instead of IgM, and antibody affinity is much greater. Once released, the various forms of antibodies (Ig) possess a number of effector functions to engage the antigen. Microbes, tumor cells, or foreign proteins can express several types of antigens and multiple copies of these antigens. If the microbial antigen to which an antibody is directed is associated with the toxic portion of a molecule, then the antibody can neutralize the toxin. The production of neutralizing antibodies is frequently a problem in the therapeutic application of biotechnolog -derived recombinant proteins as neutralizing antibodies can become a rate-limiting step during preclinical testing because animals may perceive the recombinant protein, especially when humanized, as non-self.

[0046] Most of the effector functions of humoral immunity are mediated by antibody-activated processes, but they are also key players in innate immunity. For example, the classical activation pathway of the complement cascade is triggered by antigen-antibody complexes and is specifically mediated by the constant region of the Ig molecule. Both IgM and IgG can activate the complement system, which results in the biologically active components identified previously, including the lytic unit, the chemotactic factors, and the complement peptides, which opsonize the microbe to facilitate phagocytosis. IgM and IgG can function to opsonize some microbes independent of complement activation in an antigen-dependent fashion because macrophages and neutrophils have receptors on their surface, which recognize the constant region of Ig (Fc receptors, FcRs). FcRs also play a maj or role in the ability' of IgG to participate in a process known as ‘antibody-dependent cellular cytotoxicity,’ whereby antigen-specific antibody attaches via FcRs to certain types of cells, including NK. cells, enabling these cells to attach intimately to the target cell and trigger cell death. Finally, FcRs are also the primary effector mechanism for IgE, which is the principal immune defense against certain types of parasitic infections (most notably, helminths) and is produced primarily by the external immune system along secretory surfaces. IgE binds to FcR on the surface of mast cells and basophils. Once bound to FcR, IgE can sen e as an antigen-specific receptor to trigger the release of proinflammatory factors, including vasoactive amines (e.g., histamine) and products of the arachidonic cascade (e.g., leucotrienes and prostaglandins). Systemic immunity is mediated by IgM and IgG, the latter being the major form of Ig found in the blood. Local immunity is mediated primarily by IgA and IgE.

[0047] As known to the skilled person in the art, autoimmune disease (AD) originates in the adaptive immune system. AD occurs when adaptive immune cells lose their ability to maintain self-tolerance of human cells. As a result, the immune system begins attacking healthy tissues as though they were infectious agents. Some ADs are organ-specific, whereas others can affect multiple parts of the body. Recurrent fever and chronic inflammation can be attributed to autoimmune disease. However, many possible symptoms are unique to AD, including hair loss, dry mouth, temperature sensitivity’, muscle weakness, reproductive issues, and more. A variety of conditions including environment, hormones, injury', infection, and genes can all play a role in initiating autoimmunity. AD is thought to be triggered by a combination of multiple factors not limited to genetics. Although the exact causes remain unknown, researchers believe that a variety of conditions including environment, hormones, injury, infection, and genes could all play a role in initiating autoimmunity. Autoimmune conditions are quite common. Current data estimates that ADs affect at least 14 million people in the U.S. alone. There are 80-100 known autoimmune and autoimmune-related conditions, including Hashimoto’s thyroiditis. Type 1 diabetes, Sjogren’s, and celiac disease. Gender prevalence in AD is well documented. In fact, around 80% of those diagnosed are women. While ADs can affect anyone at any age, the majority' tend to appear during adulthood.

[0048] Autoinflammatory (AIF) diseases only involve the innate immune system. AIFs occur when innate immune cells are activated without an infection or injury being present. This mishap kickstarts the release of cytokines and other immune responses, causing fever and inflammation. Recurring episodes of high fever are the primary' symptom of AIF. Similar to some autoimmune diseases, autoinflammatory symptoms can be widespread, affecting the joints, gastrointestinal tract, skin, eyes, and internal organs.

[0049] As used herein, a "regulatory element” can refer to promoters, enhancers, internal ribosomal entry' sites (IRES), and other expression control elements (e.g., transcription termination signals, such as polyadenylation signals and poly-U sequences). Regulatory elements can include those that direct constitutive expression of a nucleotide sequence in many types of host cells and those that direct expression of the nucleotide sequence only in certain host cells (e.g., tissue-specific regulatory' sequences).

[0050] As used herein, "inhibit." “inhibiting”, and “inhibition” mean to diminish or decrease an activity, level, response, condition, severity, disease, or other biological parameter (such as the level of circulating IgG and / or circulating IgM or the level of surface-bound IgM on B cells). This can include, but is not limited to, the complete ablation of the activity', level, response, condition, severity', disease, or other biological parameter (such as the level of circulating IgG and / or IgM or the level of surface-bound IgM on B cells). This can also include, for example, a 10% inhibitionor reduction in the activity, level, response, condition, severity, disease, or other biological parameter as compared to the native or control level (e.g., a subj ect not having a disease or disorder such as a genetic disease or disorder). Thus, in an aspect, the inhibition or reduction can be a 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or any amount of reduction in between as compared to native or control levels. In an aspect, the inhibition or reduction can be 10-20%, 20-30%, 30-40%, 40-50%, 50-60%, 60-70%, 70-80%, 80-90%, or 90-100% as compared to native or control levels. In an aspect, the inhibition or reduction can be 0-25%, 25-50%, 50-75%, or 75- 100% as compared to native or control levels. In an aspect, a native or control level can be a predisease or pre-disorder level.

[0051] The words "treat" or “treating’’ or “treatment” include palliative treatment, that is, treatment designed for the relief of symptoms rather than the curing of the disease, pathological condition, or disorder; preventative treatment, that is, treatment directed to minimizing or partially or completely inhibiting the development of the associated disease, pathological condition, or disorder; and supportive treatment, that is, treatment employed to supplement another specific therapy directed toward the improvement of the associated disease, pathological condition, or disorder. In an aspect, the terms cover any treatment of a subject, including a mammal (e.g., a human), and includes: (i) preventing the undesired physiological change, disease, pathological condition, or disorder from occurring in a subject that can be predisposed to the disease but has not yet been diagnosed as having it; (ii) inhibiting the physiological change, disease, pathological condition, or disorder, i.e., arresting its development; or (iii) relieving the physiological change, disease, pathological condition, or disorder, i.e., causing regression of the disease. For example, in an aspect, treating a disease or disorder can reduce the severity of an established a disease or disorder in a subject by l%-100% as compared to a control (such as, for example, an individual not having a genetic disease or disorder). In an aspect, treating can refer to a 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100% reduction in the severity of a disease or disorder (such as a genetic disease or disorder). For example, treating a disease or disorder can reduce one or more symptoms of a disease or disorder in a subject by 1 %-l 00% as compared to a control (such as, for example, an individual not having a genetic disease or disorder). In an aspect, treating can refer to 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100% reduction of one or more symptoms of an established a disease or disorder. It is understood that treatment does not necessarily refer to a cure or complete ablation or eradication of a disease or disorder. However, in an aspect, treatment can refer to a cure or complete ablation or eradication of a disease or disorder.

It is understood that where reduce, inhibit, or prevent are used herein, unless specifically indicated otherwise, the use of the other two words is also expressly disclosed. In an aspect, preventing a disease or disorder having chromatin deregulation and / or chromatin dysregulation is intended. The words “prevent”, “preventing”, and “prevention” also refer to prophylactic or preventative measures for protecting or precluding a subject (e.g., an individual) not having a given a disease or disorder (such as a genetic disease or disorder) or related complication from progressing to that complication.

[0053] As used herein, the terms “administering” and “administration” refer to any method of providing one or more of the disclosed enzymes, the disclosed recombinant enzymes, the disclosed isolated nucleic acid molecules, the disclosed vectors, the disclosed pharmaceutical formulations, or any combination thereof to a subject. Such methods are well known to those skilled in the art and include, but are not limited to, the following: oral administration, transdermal administration, administration by inhalation, nasal administration, topical administration, in utero administration, intrahepatic administration, intravaginal administration, ophthalmic administration, intraaural administration, otic administration, intracerebral administration, rectal administration, sublingual administration, buccal administration, and parenteral administration, including injectable such as intravenous administration, intra-CSF administration, intra-arterial administration, intramuscular administration, and subcutaneous administration. Administration can also include hepatic intra-arterial administration or administration through the hepatic portal vein (HPV). Administration of a disclosed enzy me, a disclosed recombinant enzyme, a disclosed isolated nucleic acid molecule, a disclosed vector, a disclosed pharmaceutical composition, a disclosed therapeutic agent, a disclosed immune modulator, a disclosed proteasome inhibitor, a disclosed small molecule, a disclosed endonuclease, a disclosed oligonucleotide, and / or a disclosed RNA therapeutic can comprise administration directly into the CNS or the PNS. Administration can be continuous or intermittent. Administration can comprise a combination of one or more route.

[0054] In an aspect, the skilled person can determine an efficacious dose, an efficacious schedule, and an efficacious route of administration for the disclosed enzymes, the disclosed recombinant enzymes, the disclosed isolated nucleic acid molecules, the disclosed vectors, the disclosed pharmaceutical formulations, or any combination thereof to treat or prevent a disease or disorder (such as genetic disease or disorder). In an aspect, the skilled person can also alter, change, or modify an aspect of an administering step to improve efficacy of the disclosed enzymes, the disclosed recombinant enzy mes, the disclosed isolated nucleic acid molecules, the disclosed vectors, the disclosed pharmaceutical formulations, or any combination thereof.

[0055] By '‘determining the amount” is meant both an absolute quantification of a particular analyte (e.g., level of IgG and / or IgM) or a determination of the relative abundance of a particular analyte (e.g., level of IgG and / or IgM compared to a control / reference level). The phrase includes both direct or indirect measurements of abundance or both.

[0056] As used herein. IdeZ is a cysteine protease that inactivates IgG antibodies by cleaving IgG at the lower hinge region of the heavy chain producing one F(ab’)? and one homodimeric Fc fragment.

[0057] As used herein, the term “pharmaceutically acceptable carrier'’ refers to sterile aqueous or nonaqueous solutions, dispersions, suspensions or emulsions, as well as sterile powders for reconstitution into sterile injectable solutions or dispersions just prior to use. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents, or vehicles include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol and the like), carboxymethylcellulose and suitable mixtures thereof, vegetable oils (such as olive oil) and injectable organic esters such as ethyl oleate. In an aspect, a pharmaceutical carrier employed can be a solid, liquid, or gas. In an aspect, examples of solid carriers can include lactose, terra alba, sucrose, talc, gelatin, agar, pectin, acacia, magnesium stearate, and stearic acid. In an aspect, examples of liquid carriers can include sugar syrup, peanut oil, olive oil, and water. In an aspect, examples of gaseous carriers can include carbon dioxide and nitrogen. In preparing a disclosed composition for oral dosage form, any convenient pharmaceutical media can be employed. For example, water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents and the like can be used to form oral liquid preparations such as suspensions, elixirs and solutions; while carriers such as starches, sugars, microcry stalline cellulose, diluents, granulating agents, lubricants, binders, disintegrating agents, and the like can be used to form oral solid preparations such as powders, capsules and tablets. Because of their ease of administration, tablets and capsules are the preferred oral dosage units whereby solid pharmaceutical carriers are employed. Optionally, tablets can be coated by standard aqueous or nonaqueous techniques. Proper fluidity can be maintained, for example, by the use of coating materials such as lecithin, by the maintenance of the required particle size in the case of dispersions and by the use of surfactants. These compositions can also contain adjuvants such as preservatives, wetting agents, emulsifying agents and dispersing agents. Prevention of the action of microorganisms can be ensured by the inclusion of various antibacterial and antifungal agents such as paraben, chlorobutanol, phenol, sorbic acid and the like. It can also be desirable to include isotonic agents such as sugars, sodium chloride and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the inclusion of agents, such as aluminum monostearate and gelatin, which delay absorption. Injectable depot forms are made by forming microencapsule matrices of the drug in biodegradable polymers such aspolylactide-polygly colide, poly(orthoesters) and poly(anhydrides). Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions that are compatible with body tissues. The injectable formulations can be sterilized, for example, by filtration through a bacterial -retaining filter 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 media just prior to use. Suitable inert carriers can include sugars such as lactose. Desirably, at least 95% by weight of the particles of the active ingredient have an effective particle size in the range of 0.01 to 10 micrometers.

[0058] As used herein, the term '‘excipient” refers to an inert substance which is commonly used as a diluent, vehicle, preservative, binder, or stabilizing agent, and includes, but is not limited to, proteins (e.g., serum albumin, etc.), amino acids (e.g., aspartic acid, glutamic acid, lysine, arginine, glycine, histidine, etc.), fatty acids and phospholipids (e.g., alkyl sulfonates, caprylate, etc.), surfactants (e.g., SDS, polysorbate, nonionic surfactant, etc.), saccharides (e.g., sucrose, maltose, trehalose, etc.) and polyols (e.g., mannitol, sorbitol, etc.). See, also, for reference. Remington’s Pharmaceutical Sciences, (1990) Mack Publishing Co., Easton, Pa., which is hereby incorporated by reference in its entirety.

[0059] As used herein, “concurrently” means (1) simultaneously in time, or (2) at different times during the course of a common treatment schedule.

[0060] The term “contacting” as used herein refers to bringing one or more of the disclosed enzymes, the disclosed recombinant enzymes, the disclosed isolated nucleic acid molecules, the disclosed vectors, the disclosed pharmaceutical formulations, or any combination thereof together with a target area or intended target area (e.g. a cleavage site on IgG (SEQ ID NO: 111 - SEQ ID NO: 118) and / or IgM (SEQ ID NO: 110)) in such a manner that the one or more of the disclosed isolated nucleic acid molecules, disclosed vectors, disclosed pharmaceutical formulations, or a combination thereof exert an effect on the intended target or targeted area either directly or indirectly. A target area can comprise one or more cells, and in an aspect, one or more cells can be in a subject. A target area or intended target area can be one or more of a subject’s organs (e.g., lungs, heart, liver, kidney, brain, etc.). In an aspect, a target area or intended target area can be any organ, tissue, or cells that are affected by a disease or disorder (such as a genetic disease or disorder).

[0061] As used herein, “determining” can refer to measuring or ascertaining the presence and severity of a disease or disorder, such as, for example, a genetic disease or disorder. Methods and techniques used to determine the presence and / or severity of a disease or disorder are ty pically known to the medical arts. For example, the art is familiar with the ways to identify and / ordiagnose the presence, severity, or both of a disease or disorder (such as, for example, a genetic disease or disorder).

[0062] As used herein, “effective amount'’ and “amount effective” can refer to an amount that is sufficient to achieve the desired result such as, for example, the treatment and / or prevention of a disease or disorder (e.g., a genetic disease or disorder) or a suspected disease or disorder. As used herein, the terms “effective amount” and “amount effective” can refer to an amount that is sufficient to achieve the desired an effect on an undesired condition (e.g., a disease or disorder). For example, a “therapeutically effective amount” refers to an amount that is sufficient to achieve the desired therapeutic result or to have an effect on undesired symptoms, but is generally insufficient to cause adverse side effects. In an aspect, “therapeutically effective amount” means an amount of a disclosed enzy me, a disclosed recombinant enzyme, a disclosed isolated nucleic acid molecule, a disclosed vector, or a disclosed pharmaceutical formulation; that (i) treats the particular disease, condition, or disorder (e.g., a genetic disease or disorder), (ii) attenuates, ameliorates, or eliminates one or more symptoms of the particular disease, condition, or disorder e.g., a genetic disease or disorder), or (iii) delays the onset of one or more symptoms of the particular disease, condition, or disorder described herein (e.g., a genetic disease or disorder). The specific therapeutically effective dose level for any particular patient will depend upon a variety' of factors including the disorder being treated and the severity of the disorder; the disclosed enzymes, the disclosed recombinant enzymes, the disclosed isolated nucleic acid molecules, disclosed vectors, disclosed pharmaceutical formulations employed; the disclosed methods employed; the age, body weight, general health, sex and diet of the patient; the time of administration; the route of administration; the rate of excretion of the disclosed isolated nucleic acid molecules, disclosed vectors, or disclosed pharmaceutical formulations employed; the duration of the treatment; drugs used in combination or coincidental with the disclosed isolated nucleic acid molecules, disclosed vectors, or disclosed pharmaceutical formulations employed, and other like factors well known in the medical arts. For example, it is within the skill of the art to start doses of the disclosed enzymes, the disclosed recombinant enzymes, the disclosed isolated nucleic acid molecules, disclosed vectors, or disclosed pharmaceutical formulations at levels lower than those required to achieve the desired therapeutic effect and to gradually increase the dosage until the desired effect is achieved. If desired, then the effective daily dose can be divided into multiple doses for purposes of administration. Consequently, a single dose of the disclosed isolated nucleic acid molecules, disclosed vectors, or disclosed pharmaceutical formulations can contain such amounts or submultiples thereof to make up the daily dose. The dosage can be adjusted by the individual physician in the event of any contraindications. Dosage can vary, and can be administered in one or more dose administrations daily, for one or several days. Guidancecan be found in the literature for appropriate dosages for given classes of pharmaceutical products. In further various aspects, a preparation can be administered in a “prophylactically effective amount”; that is, an amount effective for prevention of a disease or condition, such as, for example, a disease or disorder due to a missing, deficient, and / or mutant protein or enzyme.

[0063] As used herein. “RNA therapeutics” can refer to the use of oligonucleotides to target RNA. RNA therapeutics can offer the promise of uniquely targeting the precise nucleic acids involved in a particular disease with greater specificity, improved potency, and decreased toxicity. This could be particularly powerful for genetic diseases where it is most advantageous to aim for the RNA as opposed to the protein. In an aspect, a therapeutic RNA can comprise one or more expression sequences. As known to the art, expression sequences can comprise an RNAi, shRNA, mRNA, non-coding RNA (ncRNA), an antisense such as an antisense RNA, miRNA, morpholino oligonucleotide, peptide-nucleic acid (PNA) or ssDNA (with natural, and modified nucleotides, including but not limited to, LNA, BNA, 2’-O-Me-RNA, 2 -MEO-RNA, 2'-F-RNA), or analog or conjugate thereof. In an aspect, a disclosed therapeutic RNA can comprise one or more long non-coding RNA (IncRNA), such as, for example, along intergenic non-coding RNA (lincRNA), pre-transcript, pre-miRNA, pre-mRNA, competing endogenous RNA (ceRNA), small nuclear RNA (snRNA), small nucleolar RNA (snoRNA), pseudo-gene, rRNA, or tRNA. In an aspect, ncRNA can be piwi-interacting RNA (piRNA), primary miRNA (pri-miRNA), or premature miRNA (pre-miRNA). In an aspect, a disclosed therapeutic RNA or an RNA therapeutic can comprise antisense oligonucleotides (ASOs) that inhibit mRNA translation, oligonucleotides that function via RNA interference (RNAi) pathway, RNA molecules that behave like enzymes (ribozymes), RNA oligonucleotides that bind to proteins and other cellular molecules, and ASOs that bind to mRNA and form a structure that is recognized by RNase H resulting in cleavage of the mRNA target. In an aspect, RNA therapeutics can comprise RNAi and ASOs that inhibit mRNA translation. Generally speaking, as know n to the art, RNAi operates sequence specifically and post-transcriptionally by activating ribonucleases which, along with other enzymes and complexes, coordinately degrade the RNA after the original RNA target has been cut into smaller pieces while antisense oligonucleotides bind to their target nucleic acid via Watson-Crick base pairing, and inhibit or alter gene expression via steric hindrance, splicing alterations, initiation of target degradation, or other events.

[0064] As used herein, “peptide,” “polypeptide,” and “protein” are used interchangeably, and refer to a compound comprised of amino acid residues covalently linked by peptide bonds. A protein must contain at least two amino acids and there is no limitation on the maximum number of amino acids that can comprise a protein’s sequence. The term “peptide” can refer to a short chain of amino acids including, for example, natural peptides, recombinant peptides, syntheticpeptides, or any combination thereof. Proteins and peptides can include, for example, biologically active fragments, substantially homologous polypeptides, oligopeptides, homodimers, heterodimers, variants of polypeptides, modified polypeptides, derivatives, analogs, and fusion proteins, among others.

[0065] "Nucleic acid” or "oligonucleotide” or "polynucleotide” as used herein means at least two nucleotides covalently linked together. The depiction of a single strand can also define the sequence of the complementary strand. Thus, a nucleic acid can encompass the complementary strand of a depicted single strand. Many variants of a nucleic acid can be used for the same purpose as a given nucleic acid. Thus, a nucleic acid can encompass substantially identical nucleic acids and complements thereof. A single strand can provide a probe that can hybridize to a target sequence under stringent hybridization conditions. Thus, a nucleic acid can encompass a probe that hybridizes under stringent hybridization conditions. A nucleic acid can be single-stranded, or double-stranded, or can contain portions of both double-stranded and single-stranded sequence. The nucleic acid can be DNA, both genomic and cDN A, RN A, or a hybrid, where the nucleic acid can contain combinations of deoxy ribo- and ribo-nucleotides, and combinations of bases including uracil, adenine, thymine, cytosine, guanine, inosine, xanthine hypoxanthine, isocytosine and isoguanine. Nucleic acids can be obtained by chemical synthesis methods or by recombinant methods. Also as used herein, the terms “nucleic acid,” “nucleic acid molecule,” "nucleic acid construct,” "nucleotide sequence”, and "polynucleotide” can refer to RNA or DNA that is linear or branched, single or double stranded, or a hybrid thereof. The term can encompass RNA / DNA hybrids. When dsRNA is produced synthetically, less common bases, such as inosine, 5- methylcytosine, 6-methyladenine. hypoxanthine and others can also be used for antisense, dsRNA, and ribozyme pairing. For example, polynucleotides that contain C-5 propyne analogues of uridine and cytidine have been shown to bind RNA with high affinity and to be potent antisense inhibitors of gene expression. Other modifications, such as modification to the phosphodiester backbone, or the 2'-hy droxy in the ribose sugar group of the RNA can also be made. A "synthetic” nucleic acid or polynucleotide, as used herein, refers to a nucleic acid or polynucleotide that is not found in nature but is constructed by the hand of man and therefore is not a product of nature.

[0066] A “polynucleotide” is a sequence of nucleotide bases, and may be RNA, DNA, or DNA- RNA hybrid sequences (including both naturally occurring and non-naturally occurring nucleotides).

[0067] A "fragment” or "portion” of a nucleotide sequence can be understood to mean a nucleotide sequence of reduced length relative (e.g., reduced by 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 or more nucleotides) to a reference nucleic acid or nucleotide sequence and comprising, consisting essentially of, or consisting of a nucleotide sequence ofcontiguous nucleotides identical or almost identical (e.g., 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% identical) to the reference nucleic acid or nucleotide sequence. Such a nucleic acid fragment or portion according to the disclosure can be. where appropriate, included in a larger polynucleotide of which it is a constituent. In an aspect, a fragment or portion of a nucleotide sequence or nucleic acid sequence can comprise the sequence encoding an exon having one or more mutations.

[0068] A “fragment’' or “portion” of an amino acid sequence can be understood to mean an amino acid sequence of reduced length relative (e.g., reduced by 1, 2. 3, 4, 5. 6, 7, 8. 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, 200, 250, or more ammo acids) to a reference amino acid sequence and comprising, consisting essentially of, or consisting of an amino acid sequence of contiguous amino acids identical or almost identical (e.g., 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% identical) to the reference amino acid sequence. Such an amino acid fragment or portion according to the disclosure can be, where appropriate, included in a larger amino acid sequence of which it is a constituent.

[0069] “Complement” or “complementary” as used herein means a nucleic acid can mean Watson-Crick (e.g., A-T / U and C-G) or Hoogsteen base pairing between nucleotides or nucleotide analogs of nucleic acid molecules. “Complementarity” refers to a property shared between two nucleic acid sequences, such that when they are aligned antiparallel to each other, the nucleotide bases at each position will be complementary.

[0070] As used herein, “operably linked” means that expression of a gene or a transgene is under the control of a promoter with which it is spatially connected. A promoter can be positioned 5’ (upstream) or 3’ (downstream) of a gene under its control. The distance between the promoter and a gene can be approximately the same as the distance between that promoter and the gene it controls in the gene from which the promoter is derived. As is known in the art, variation in this distance can be accommodated without loss of promoter function.

[0071] As used herein, “promoter” or “promoters” are known to the art. Depending on the level and tissue-specific expression desired, a variety of promoter elements can be used. A promoter can be tissue-specific or ubiquitous and can be constitutive or inducible, depending on the pattern of the gene expression desired. A promoter can be native (endogenous) or foreign (exogenous) and can be a natural or a synthetic sequence. By foreign or exogenous, it is intended that the transcriptional initiation region is not found in the wild-type host into which the transcriptional initiation region is introduced.

[0072] '‘Tissue-specific promoters” are known to the art and include, but are not limited to, neuron-specific promoters, muscle-specific promoters, liver-specific promoters, skeletal musclespecific promoters, and heart-specific promoters.

[0073] “Liver-specific promoters” are known to the art and include, but are not limited to, the thyroxin binding globulin (TBG) promoter, the al-microglobulin / bikunin enhancer / thyroid hormone-binding globulin promoter, the human albumin (hALB) promoter, the thyroid hormone- binding globulin promoter, the a- 1 -anti -trypsin promoter, the bovine albumin (bAlb) promoter, the murine albumin (mAlb) promoter, the human al -antitrypsin (hAAT) promoter, the ApoEhAAT promoter comprising the ApoE enhancer and the hAAT promoter, the transthyretin (TTR) promoter, the liver fatty acid binding protein promoter, the hepatitis B virus (HBV) promoter, the DC172 promoter comprising the hAAT promoter and the al -microglobulin enhancer, the DC 190 promoter comprising the human albumin promoter and the prothrombin enhancer, or any other natural or synthetic liver-specific promoter.

Factors that can regulate an inducible promoter include, but are not limited to, chemical agents (e g., the metallothionein promoter or a hormone inducible promoter), temperature, and light.

[0076] As used herein, the term “seroty pe” is a distinction used to refer to an AAV having a capsid that is serologically distinct from other AAV serotypes. Serologic distinctiveness can be determined by the lack of cross-reactivity between antibodies to one AAV as compared to another AAV. Such cross-reactivity differences are usually due to differences in capsid protein sequences / antigenic determinants (e.g., due to VP1, VP2, and / or VP3 sequence differences of AAV serotypes).

[0077] As used herein, “tropism’’ refers to the specificity of an AAV capsid protein present in an AAV viral particle, for infecting a particular type of cell or tissue. The tropism of an AAV capsid for a particular type of cell or tissue may be determined by measuring the ability of AAV vector particles comprising the hybrid AAV capsid protein to infect or to transduce a particular type of cell or tissue, using standard assays that are well-known in the art such as those disclosed in the examples of the present application. As used herein, the term “liver tropism” or “hepatic tropism” refers to the tropism for liver or hepatic tissue and cells, including hepatocytes.

[0078] “Sequence identity” and “sequence similarity” can be determined by alignment of two peptide or two nucleotide sequences using global or local alignment algorithms. Sequences may then be referred to as “substantially identical” or “essentially similar” when they are optimally aligned. For example, sequence similarity or identity can be determined by searching against databases such as FASTA, BLAST, etc., but hits should be retrieved and aligned pairwise to compare sequence identity. Two proteins or two protein domains, or two nucleic acid sequences can have “substantial sequence identity” if the percentage sequence identity is at least 70%, 75%, 80%, 85%, 90%, 95%, 98%, 99% or more, preferably 90%, 95%, 98%, 99% or more. Such sequences are also referred to as “variants” herein, e.g., other variants of a missing, deficient, and / or mutant protein or enzyme. It should be understood that sequence with substantial sequence identity do not necessarily have the same length and may differ in length. For example, sequences that have the same nucleotide sequence but of which one has additional nucleotides on the 3’- and / or 5’-side are 100% identical.

[0079] A “heterologous” or a “recombinant” nucleotide or amino acid sequence as used interchangeably herein can refer to a nucleotide or an amino acid sequence not naturally associated with a host cell into which it is introduced, including non-naturally occurring multiple copies of a naturally occurring nucleotide or amino acid sequence.

[0080] Different nucleic acids or proteins having homology' can be referred to as “homologues”. The term homologue includes homologous sequences from the same and other species and orthologous sequences from the same and other species. “Homology” refers to the level of similarity' betw een two or more nucleic acid and / or amino acid sequences in terms of percent of positional identity (i.e., sequence similarity or identity). Homology' also refers to the concept of similar functional properties among different nucleic acids or proteins. Thus, the disclosed compositions and disclosed methods can comprise homologues to the disclosed nucleotide sequences and / or disclosed polypeptide sequences.

[0081] “Orthologous,” as used herein, can refer to homologous nucleotide sequences and / or amino acid sequences in different species that arose from a common ancestral gene during speciation. A homologue of a disclosed nucleotide sequence or a disclosed polypeptide can havesubstantial sequence identity (e.g., at least about 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, and / or 100%) to a disclosed nucleotide sequence or a disclosed polypeptide.

[0082] As used herein, “codon optimization” can refer to a process of modifying a nucleic acid sequence for enhanced expression in the host cells of interest by replacing one or more codons or more of the native sequence with codons that are more frequently or most frequently used in the genes of that host cell while maintaining the native amino acid sequence. Various species exhibit particular bias for certain codons of a particular amino acid. As contemplated herein, genes can be tailored for optimal gene expression in a given organism based on codon optimization. Codon usage tables are readily available, for example, at the “Codon Usage Database.” Many methods and software tools for codon optimization have been reported previously . (See, for example, genomes .urv.es / OPTIMIZER / ) .

[0083] For example, a codon is a sequence of three nucleotides that encodes for a specific amino acid in the synthesis of a protein. There are 64 distinct codons, but only 20 amino acids, leading to the degeneracy of the genetic code. For instance, the amino acid Leucine can be encoded with six synonymous codons CUU, CUC, CUA, CUG, UUA and UUG whereas Cysteine can be encoded with two codons UGU and UGC. Overall, 2 of the 20 amino acids can be encoded with 1 codon, 9 with 2 codons, 1 with 3 codons, 5 with 4 codons and 3 with 6 codons leading to 61 essential codons. The remaining three codons are stop codons and are reserved for termination of protein formation. Codon degeneracy leads to many possible ways of encoding a protein, e.g. a typical 375-amino acid protein in humans can be potentially encoded by 10207 different codon sequences. All possible encodings and resulting sequences are not equally likely to be observed in nature; however, as some synonymous codons are more frequently used than others in encoding a particular amino acid in a particular organism. This phenomenon is called ‘codon usage bias’ or ‘codon bias’. As an example, Leucine is encoded 39.5% of the time with codon CUG in Homo sapiens, whereas the same codon is used 11.1% of the same amino acid’s encoding in Saccharomyces cerevisiae (Nakamura et al., 2000).

[0084] As used herein, “immune tolerance,” “immunological tolerance,” and “immunotolerance” refers to a state of unresponsiveness or blunted response of the immune system to substances (e.g., protein replacement therapy, enzyme replacement therapy, recombinant product, a transplanted organ, a vector protein, etc.) that have the capacity to elicit an immune response in a subject. Immune tolerance is induced by prior exposure to a specific antigen. Immune tolerance can be determined in a subject by measuring antibodies against a particular antigen (such as, for example, to an HLA on a transplanted organ, an enzy me or therapeutic protein as part of replacementtherapy, a viral vector, an AAV capsid protein). Low or absent antibody titers over time is an indicator of immune tolerance or the efficacy of a disclosed enz me or disclosed recombinant enzy me. For example, immune tolerance can be established by having IgG antibody titers of less than or equal to about 12,000, 11,500, 11,000. 10.500, 10,000, 9,500. 9,000, 8,500, 8,000, 7.500, 7,000, 6.500, or 6,000 following gene therapy (such as the administration of the transgene encoding, for example, a missing, deficient, and / or mutant protein or enzyme), protein replacement therapy, enzyme replacement therapy, or a recombinant product.

[0085] As known to the art, antibodies (Abs) can mitigate AAV infection through multiple mechanisms by binding to AAV capsids and blocking critical steps in transduction such as cell surface attachment and uptake, endosomal escape, productive trafficking to the nucleus, or uncoating as well as promoting AAV opsonization by phagocytic cells, thereby mediating their rapid clearance from the circulation. For example, in humans, serological studies reveal a high prevalence of NAbs in the worldwide population, with about 67% of people having antibodies against AAV1, 72% against AAV2, and approximately 40% against AAV serotypes 5 through 9. Vector immunogenicity represents a major challenge in re-administration of AAV vectors.

[0086] In an aspect, also disclosed herein are partial self-complementary7parvovirus (e.g., a disclosed AAV) genomes, plasmid vectors encoding the parvovirus genomes, and parvovirus (e.g., a disclosed AAV) particles including such genomes. In an aspect, provided herein is a plasmid vector comprising a nucleotide sequence encoding a disclosed parvovirus genome such as for example, a disclosed AAV. In an aspect, provided herein is a partial self-complementary' parvovirus genome including a payload construct, parvovirus ITRs flanking the payload construct, and a self-complementary region flanking one of the ITRs. A self-complementary7region can comprise a nucleotide sequence that is complementary7to the payload construct. A disclosed self- complementary region can have a length that is less the entire length of the pay load construct.

[0087] In an aspect, a disclosed self-complementary7region of a disclosed parvovirus genome can comprise a minimum length, while still having a length that is less the entire length of the payload construct. In an aspect, a disclosed self-complementary region can comprise at least 50 bases in length, at least 100 bases in length, at least 200 in length, at least 300 bases in length, at least 400 bases in length, at least 500 bases in length, at least 600 bases in length, at least 700 bases in length, at least 800 bases in length, at least 900 bases in length, or at least 1,000 bases in length.

[0088] In an aspect, a “self-complementary parvovirus genome” can be a single stranded polynucleotide having, in the 5’ to 3’ direction, a first parvovirus ITR sequence, a heterologous sequence (e.g., payload construct comprising, for example, a desired gene), a second parvovirus ITR sequence, a second heterologous sequence, wherein the second heterologous sequence is complementary to the first heterologous sequence, and a third parvovirus ITR sequence. Incontrast to a self-complementary genome, a "partial self-complementary genome” does not include three parvovirus ITRs and the second heterologous sequence that is complementary to the first heterologous sequence has a length that is less than the entire length of the first heterologous sequence (e.g., payload construct). Accordingly, a partial self-complementary genome is a single stranded polynucleotide having, in the 5’ to 3’ direction or the 3’ to 5’ direction, a first parvovirus ITR sequence, a heterologous sequence (e.g., payload construct), a second parvovirus ITR sequence, and a self-complementary region that is complementary to a portion of the heterologous sequence and has a length that is less than the entire length the heterologous sequence.

[0089] As used herein, “immune-modulating” refers to the ability of a disclosed enzyme, a disclosed recombinant enzyme, a disclosed isolated nucleic acid molecule, a disclosed vector, a disclosed pharmaceutical formulation, or a disclosed agent to alter (modulate) one or more aspects of the immune system. The immune system functions to protect the organism from infection and from foreign antigens by cellular and humoral mechanisms involving lymphocytes, macrophages, and other antigen-presenting cells that regulate each other by means of multiple cell-cell interactions and by elaborating soluble factors, including lymphokines and antibodies, that have autocrine, paracrine, and endocrine effects on immune cells.

[0090] As used herein, “immune modulator” refers to an agent that is capable of adjusting a given immune response to a desired level (e.g., as in immunopotentiation, immunosuppression, or induction of immunologic tolerance). Examples of immune modulators include but are not limited to, a disclosed immune modulator can comprise aspirin, azathioprine, belimumab, betamethasone dipropionate, betamethasone valerate, bortezomib, bredinin, cyazathioprine, cyclophosphamide, cyclosporine, deoxyspergualin, didemnin B, fluocinolone acetonide, folinic acid, ibuprofen.

In an aspect, a disclosed immune modulator can comprise one or more Treg (regulatory T cells) infusions (e.g., antigen specific Treg cells to AAV). In an aspect, a disclosed immune modulator can be bortezomib or SVP-Rapamycin. In an aspect, an immune modulator can be administered by any suitable route of administration including, but not limited to, in utero, intra-CSF, intrathecally, intravenously, subcutaneously, trans dermally, intradermally, intramuscularly, orally, trans cutaneously, intraperitoneally (IP), or intravaginally. In an aspect, a disclosedimmune modulator can be administered using a combination of routes. Administration can also include hepatic intra-arterial administration or administration through the hepatic portal vein (HPV). Administration of an immune modulator can be continuous or intermittent, and administration can comprise a combination of one or more routes.

[0091] As used herein, the term "immunotoleranf ’ refers to unresponsiveness to an antigen (e.g., a vector, a therapeutic protein, a transgene product, etc.). An immunotolerant promoter can reduce, ameliorate, or prevent transgene-induced immune responses that can be associated with gene therapy. Assays known in the art to measure immune responses, such as immunohistochemical detection of cytotoxic T cell responses, can be used to determine whether one or more promoters can confer immunotolerant properties.

[0092] As used herein, the term “package insert” is used to refer to instructions customarily included in commercial packages of therapeutic products, that contain information about the indications, usage, dosage, administration, contraindications and / or warnings concerning the use of such therapeutic products.

[0093] As used herein, the term “in combination” in the context of the administration of other therapies (e.g., other agents) includes the use of more than one therapy (e.g., drug therapy). Administration “in combination with” one or more further therapeutic agents includes simultaneous (e.g.. concurrent) and consecutive administration in any order. The use of the term “in combination” does not restrict the order in which therapies are administered to a subject. By way of non-limiting example, a first therapy (e.g., a disclosed enzyme, a disclosed recombinant enzyme, a disclosed isolated nucleic acid molecule, a disclosed vector, a disclosed pharmaceutical formulation, or a combination thereof) may be administered prior to (e.g., 1 minute, 15 minutes, 30 minutes, 45 minutes, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 12 hours, 24 hours, 48 hours, 72 hours, 96 hours, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 8 weeks, 8 weeks, 9 weeks, 10 weeks, 11 weeks, or 12 weeks), concurrently, or after (e.g., 1 minute. 15 minutes, 30 minutes, 45 minutes, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours. 12 hours, 24 hours, 48 hours, 72 hours, 96 hours. 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 7 weeks, 8 weeks, 9 weeks, 10 weeks, 1 1 weeks, or 12 weeks or longer) the administration of a second therapy (e.g., gene therapy, enzyme replacement therapy, protein replacement therapy, recombinant product) to a subject having or diagnosed with a disease or disorder (such as a genetic disease or disorder).
