The present disclosure relates to the field of gene therapy and provides compositions and methods for ameliorating genetic disorders.
Pompe disease is a lysosomal storage disorder caused by mutations in the acid alpha-glucosidase (GAA) gene, which encodes an enzyme responsible for processing lysosomal glycogen. Patients with Pompe disease exhibit clinical phenotypes across a variety of tissues, including glycogen buildup in cells, deficits in cardiac, respiratory, and skeletal muscle function, and central nervous system pathology. Some of these deficits are significantly ameliorated by enzyme replacement therapy (ERT) using recombinant human GAA (rhGAA). Clinical efficacy has been limited by the immunogenicity of hGAA ERT and the lack of uptake of rhGAA into some affected tissues. Recently, gene therapy approaches involving the delivery of GAA have been developed for the treatment of Pompe disease. However, there is a need in the art for improved methods of administering gene therapy to patients having Pompe disease.
The present disclosure provides compositions and methods that can be used for treating glycogen storage disorders, such as type II glycogen storage disorder, which is also referred to herein as Pompe disease. Using the compositions and methods of the disclosure, a patient (e.g., a mammalian patient, such as a human patient) having Pompe disease may be administered a viral vector, such as an adeno-associated viral (AAV) vector, that contains a transgene encoding acid alpha-glucosidase (GAA). The AAV vector may be, for example, a pseudotyped AAV vector, such as an AAV vector containing AAV2 inverted terminal repeats packaged within capsid proteins from AAV8 (AAV2/8) or AAV9 (AAV2/9). The transgene may, for example, be operably linked to a transcription regulatory element, such as a promoter that induces gene expression in a muscle cell and/or a neuronal cell. Exemplary promoters that may be used in conjunction with the compositions and methods of the disclosure are a muscle creatine kinase (MCK) promoter and cytomegalovirus (CMV) promoter, among others. The AAV vector may be administered to the patient in a therapeutically effective amount, such as in an amount of from 1×1013 vector genomes (vg) per kg of body weight of the subject (vg/kg) to 3×1014 vg/kg (e.g., in an amount of from 3×1013 vg/kg to 2×1014 vg/kg, 4×1013 vg/kg to 1×1014 vg/kg, 4×1013 vg/kg, 5×1013 vg/kg, 6×1013 vg/kg, 7×1013 vg/kg, 8×1013 vg/kg, 9×1013 vg/kg, or 1×1014 vg/kg).

As used herein, the term “about” refers to a value that is within 5% above or below the value being described. For example, “about 1×1013 vg/kg” as used in the context of a viral vector described herein includes quantities that are within 5% above or below 1×1013 vg/kg. Additionally, when used in the context of a list of numerical quantities, it is to be understood that the term “about,” when preceding a list of numerical quantities, applies to each individual quantity recited in the list. For example, “about 1×1013 vg/kg, 2×1013 vg/kg, or 3×1013 vg/kg” is to be construed as equivalent to individually reciting “about 1×1013 vg/kg,” “about 2×1013 vg/kg,” and “about 3×1013 vg/kg.”
As used herein in the context of a protein of interest, such as acid alpha-glucosidase (GAA), the term “activity” refers to the biological functionality that is associated with a wild-type form of the protein. For example, in the context of an enzyme, the term “activity” refers to the ability of the protein to effectuate substrate turnover in a manner that yields the product of a corresponding chemical reaction. Activity levels of enzymes, such as GAA, can be detected and quantitated, for example, using substrate turnover assays known in the art.
As used herein, the terms “administering,” “administration,” and the like refer to directly giving a patient a therapeutic agent (e.g., a viral vector) by any effective route. Exemplary routes of administration are described herein and include systemic administration routes, such as intravenous injection, as well as routes of administration directly to the central nervous system of the patient, such as by way of intrathecal injection or intracerebroventricular injection, among others.
As used herein, the terms “alanine aminotransferase” and “ALT” refer to a protein whose amino acid sequence comprises or consists of an amino acid sequence of a naturally occurring wild-type ALT protein (e.g., ALT1 and ALT2) as well as proteins whose amino acid sequence comprises or consists of an amino acid sequence of a naturally occurring allelic variants of ALT (GPT or GPT2 e.g., splice variants or allelic variants). Human GPT nucleic acid sequence is provided in NCBI RefSeq Acc. No. NM_005309.2, and an exemplary wild-type ALT1 amino acid sequence is provided in NCBI RefSeq Acc. No. NP_005300.

As used herein, the term “transaminasemia” and “transaminitis” refer synonymously to a condition where levels of liver enzymes, called transaminases, are elevated. “Transaminase elevation,” “elevated liver enzymes,” and “hypertransaminasemia” are other terms sometimes referring to the same thing.
As used herein, a “combination therapy” means that two (or more) different agents or treatments are administered to a subject as part of a defined treatment regimen for a particular disease or condition (e.g., a glycogen storage disorder). In some embodiments, a “combination therapy” may include a procedure. The treatment regimen defines the doses and periodicity of administration of each agent such that the effects of the separate agents on the subject overlap. In some embodiments, the delivery of the two or more agents is simultaneous or concurrent and the agents may be co-formulated. In other embodiments, the two or more agents are not co-formulated and are administered in a sequential manner as part of a prescribed regimen. In some embodiments, administration of two or more agents or treatments in combination is such that the reduction in a symptom, or other parameter related to the disorder is greater than what would be observed with one agent or treatment delivered alone or in the absence of the other. The effect of the two treatments can be partially additive, wholly additive, or greater than additive (e.g., synergistic). Sequential or substantially simultaneous administration of each therapeutic agent can be affected by any appropriate route including, but not limited to, oral routes, intravenous routes, intramuscular routes, and direct absorption through mucous membrane tissues. Therapeutic agents can be administered by the same route or by different routes. For example, a first therapeutic agent of the combination may be administered by intravenous injection while a second therapeutic agent of the combination may be administered enterally. In another example, an agent of the therapeutic combination may be administered by intravenous injection and a procedure of the therapeutic combination may be performed.
As used herein, the term “dose” refers to the quantity of a therapeutic agent, such as a viral vector described herein, that is administered to a subject at a particular instant for the treatment of a disorder or condition, such as to treat or ameliorate one or more symptoms of a glycogen storage disorder described herein (e.g., Pompe disease). A therapeutic agent as described herein may be administered in a single dose or in multiple doses over the course of a treatment period, as defined herein. In each case, the therapeutic agent may be administered using one or more unit dosage forms of the therapeutic agent, a term that refers to a one or more discrete compositions containing a therapeutic agent that collectively constitute a single dose of the agent. For instance, a single dose of 1×1013 vector genomes (vg) of a viral vector may be administered using, e.g., two 0.5×1013 vg unit dosage forms of the viral vector.
As used herein, the terms “effective amount,” “therapeutically effective amount,” and the like, when used in reference to a therapeutic composition, such as a vector construct described herein, refer to a quantity that, when administered to a subject (e.g., a mammal, such as a human) suffering from a disease or condition described herein, is sufficient to effect beneficial or desired results in treating the disease or condition. For example, in the context of treating glycogen storage disorders, such as Pompe disease, these terms refer to an amount of the composition sufficient to achieve a treatment response as compared to the response obtained without administration of the composition of interest. An “effective amount,” “therapeutically effective amount,” or the like, of a composition, such as a vector construct of the present disclosure, also include an amount that results in a beneficial or desired result in a subject as compared to a control.
As used herein, the terms “enzyme replacement therapy” or “ERT” refer to the administration to a subject (e.g., a mammalian subject, such as a human) suffering from a genetic loss-of-function disease of the protein that is naturally defective or deficient in the subject. For example, in the context of a subject having Pompe disease, enzyme replacement therapy refers to administration of GAA protein to such a subject. Typically, enzyme replacement therapy involves administration of the therapeutic protein to the subject chronically, over the course of multiple doses throughout the subject's life.
As used herein, the terms “express” and “expression” in the context of a gene refer to one or more of the following events: (1) production of an RNA template from a DNA sequence (e.g., by transcription); (2) processing of an RNA transcript (e.g., by splicing, editing, 5′ cap formation, and/or 3′ end processing); (3) translation of an RNA into a polypeptide or protein; and (4) post-translational modification of a polypeptide or protein. In the context of a gene that encodes a protein product, the terms “gene expression” and the like are used interchangeably with the terms “protein expression” and the like. Expression of a gene or protein of interest in a subject can manifest, for example, by detecting: an increase in the quantity or concentration of mRNA encoding corresponding protein (as assessed, e.g., using RNA detection procedures described herein or known in the art, such as quantitative polymerase chain reaction (qPCR) and RNA seq techniques), an increase in the quantity or concentration of the corresponding protein (as assessed, e.g., using protein detection methods described herein or known in the art, such as enzyme-linked immunosorbent assays (ELISA), among others), and/or an increase in the activity of the corresponding protein (e.g., in the case of an enzyme, as assessed using an enzymatic activity assay described herein or known in the art) in a sample obtained from the subject. As used herein, a cell is considered to “express” a gene or protein of interest if one or more, or all, of the above events can be detected in the cell or in a medium in which the cell resides. For example, a gene or protein of interest is considered to be “expressed” by a cell or population of cells if one can detect (i) production of a corresponding RNA transcript, such as an mRNA template, by the cell or population of cells (e.g., using RNA detection procedures described herein); (ii) processing of the RNA transcript (e.g., splicing, editing, 5′ cap formation, and/or 3′ end processing, such as using RNA detection procedures described herein); (iii) translation of the RNA template into a protein product (e.g., using protein detection procedures described herein); and/or (iv) post-translational modification of the protein product (e.g., using protein detection procedures described herein).
As used herein, the term “operably linked” refers to a first molecule joined to a second molecule, wherein the molecules are so arranged that the first molecule affects the function of the second molecule. The two molecules may or may not be part of a single contiguous molecule and may or may not be adjacent. For example, a promoter is operably linked to a transcribable polynucleotide molecule if the promoter modulates transcription of the transcribable polynucleotide molecule of interest in a cell. Additionally, two portions of a transcription regulatory element are operably linked to one another if they are joined such that the transcription-activating functionality of one portion is not adversely affected by the presence of the other portion. Two transcription regulatory elements may be operably linked to one another by way of a linker nucleic acid (e.g., an intervening non-coding nucleic acid) or may be operably linked to one another with no intervening nucleotides present.
As used herein, the term “hyperbilirubinemia” refers to a condition in which there is a higher-than-normal level of bilirubin in the blood. As used herein, the term “bilirubin” refers to a compound that occurs in the normal catabolic pathway that breaks down heme in vertebrates. This catabolism is a necessary process in the body's clearance of waste products that arise from the destruction of aged or abnormal red blood cells. As used herein, a “bilirubin test” refers to a measurement of the amount of bilirubin in a patient's blood.
As used herein, the term “level” refers to a level of a protein, as compared to a reference. The reference can be any useful reference, as defined herein. By a “decreased level” and an “increased level” of a protein is meant a decrease or increase in protein level, as compared to a reference (e.g., a decrease or an increase by about 5%, about 10%, about 15%, about 20%, about 25%, about 30%, about 35%, about 40%, about 45%, about 50%, about 55%, about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 100%, about 150%, about 200%, about 300%, about 400%, about 500%, or more; a decrease or an increase of more than about 10%, about 15%, about 20%, about 50%, about 75%, about 100%, or about 200%, as compared to a reference; a decrease or an increase by less than about 0.01-fold, about 0.02-fold, about 0.1-fold, about 0.3-fold, about 0.5-fold, about 0.8-fold, or less; or an increase by more than about 1.2-fold, about 1.4-fold, about 1.5-fold, about 1.8-fold, about 2.0-fold, about 3.0-fold, about 3.5-fold, about 4.5-fold, about 5.0-fold, about 10-fold, about 15-fold, about 20-fold, about 30-fold, about 40-fold, about 50-fold, about 100-fold, about 1000-fold, or more). A level of a protein may be expressed in mass/vol (e.g., g/dL, mg/mL, μg/mL, or ng/mL) or percentage relative to total protein in a sample.
As used herein, the terms “liver function test” and “LFT” refers to a hepatic panel (e.g., a group of blood tests that provide information about the state of a patient's liver). A hepatic panel may include measurement of the level of gamma-glutamyl transferase, the level of alkaline phosphatase, the level of aspartate aminotransferase, the level of alanine aminotransferase, the level of albumin, the level of bilirubin, the prothrombin time, the activated partial thromboplastin time, or a combination thereof.
As used herein, the term “pharmaceutical composition” refers to a mixture containing a therapeutic compound to be administered to a subject, such as a mammal, e.g., a human, in order to prevent, treat or control a particular disease or condition affecting or that may affect the subject.
As used herein, the term “pharmaceutically acceptable” refers to those compounds, materials, compositions and/or dosage forms, which are suitable for contact with the tissues of a subject, such as a mammal (e.g., a human) without excessive toxicity, irritation, allergic response and other problem complications commensurate with a reasonable benefit/risk ratio.
As used herein, the term “promoter” refers to a recognition site on DNA that is bound by an RNA polymerase. The polymerase drives transcription of the transgene. Exemplary promoters suitable for use with the compositions and methods described herein are described, for example, in Sandelin et al., Nature Reviews Genetics 8:424 (2007), the disclosure of which is incorporated herein by reference as it pertains to nucleic acid regulatory elements. Additionally, the term “promoter” may refer to a synthetic promoter, which are regulatory DNA sequences that do not occur naturally in biological systems. Synthetic promoters contain parts of naturally occurring promoters combined with polynucleotide sequences that do not occur in nature and can be optimized to express recombinant DNA using a variety of transgenes, vectors, and target cell types.
As used herein, a therapeutic agent is considered to be “provided” to a patient if the patient is directly administered the therapeutic agent or if the patient is administered a substance that is processed or metabolized in vivo to yield the therapeutic agent endogenously. For example, a patient, such as a patient having a glycogen storage disorder described herein, may be provided a nucleic acid molecule encoding a therapeutic protein (e.g., GAA) by direct administration of the nucleic acid molecule or by administration of a substance (e.g., viral vector or cell) that is processed in vivo to yield the desired nucleic acid molecule.
As used herein, the terms “subject,” “patient,” and “participant” refer to an organism that receives treatment for a particular disease or condition as described herein (such as a lysosomal storage disorder, e.g., Pompe disease). Examples of subjects, patients, and participants include mammals, such as humans, receiving treatment for a disease or condition described herein.
By a “reference” is meant any useful reference used to compare protein levels related to transaminasemia, hyperbilirubinemia, or one or more symptoms thereof. The reference can be any sample, standard, standard curve, or level that is used for comparison purposes. The reference can be a normal reference sample or a reference standard or level. A “reference sample” can be, for example, a control, e.g., a predetermined negative control value such as a “normal control” or a prior sample taken from the same subject; a sample from a normal healthy subject, such as a normal cell or normal tissue; a sample (e.g., a blood sample) from a subject not having transaminasemia, hyperbilirubinemia, or one or more symptoms thereof; a sample from a subject that is diagnosed with transaminasemia, hyperbilirubinemia, or one or more symptoms thereof; a sample from a subject that has been treated for transaminasemia, hyperbilirubinemia, or one or more symptoms thereof; or a sample of a purified protein (e.g., any described herein) at a known normal concentration. By “reference standard or level” is meant a value or number derived from a reference sample. A “normal control value” is a pre-determined value indicative of non-disease state, e.g., a value expected in a healthy control subject. Typically, a normal control value is expressed as a range (“between X and Y”), a high threshold (“no higher than X”), or a low threshold (“no lower than X”). A subject having a measured value within the normal control value for a particular biomarker is typically referred to as “within normal limits” for that biomarker. A normal reference standard or level can be a value or number derived from a normal subject not having transaminasemia, hyperbilirubinemia, or one or more symptoms thereof. In preferred embodiments, the reference sample, standard, or level is matched to the sample subject sample by at least one of the following criteria: age, weight, sex, disease stage, and overall health. A standard curve of levels of a purified protein, e.g., any described herein, within the normal reference range can also be used as a reference.
As used herein, the term “sample” refers to a specimen (e.g., blood, blood component (e.g., serum or plasma), urine, saliva, amniotic fluid, cerebrospinal fluid, tissue (e.g., placental or dermal), pancreatic fluid, chorionic villus sample, or cells) isolated from a subject. The subject may be, for example, a patient suffering from a disease described herein, such as a lysosomal storage disorder (e.g., Pompe disease).
As used herein, the term “transgene” refers to a recombinant nucleic acid (e.g., DNA or cDNA) encoding a gene product (e.g., a gene product described herein). The gene product may be an RNA, peptide, or protein. In addition to the coding region for the gene product, the transgene may include or be operably linked to one or more elements to facilitate or enhance expression, such as a promoter, enhancer(s), destabilizing domain(s), response element(s), reporter element(s), insulator element(s), polyadenylation signal(s), and/or other functional elements. Embodiments of the disclosure may utilize any known suitable promoter, enhancer(s), destabilizing domain(s), response element(s), reporter element(s), insulator element(s), polyadenylation signal(s), and/or other functional elements.
As used herein, the terms “treat” or “treatment” refer to therapeutic treatment, in which the object is to prevent or slow down (lessen) an undesired physiological change or disorder, such as the progression of a lysosomal storage disorder, such as Pompe disease, among others. Beneficial or desired clinical results include, but are not limited to, alleviation of symptoms, diminishment of extent of disease, stabilized (i.e., not worsening) state of disease, delay or slowing of disease progression, amelioration or palliation of the disease state, and remission (whether partial or total), whether detectable or undetectable. In the context of lysosomal storage disorders, such as Pompe disease, treatment of a patient may manifest in one or more detectable changes, such as an increase in the concentration of GAA protein or nucleic acids (e.g., DNA or RNA, such as mRNA) encoding GAA, or an increase in GAA activity (e.g., by 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 200%, 300%, 400%, 500%, 600%, 700%, 800%, 900%, or more. The concentration of GAA protein may be determined using protein detection assays known in the art, including ELISA assays described herein. The concentration of GAA-encoding nucleic acids may be determined using nucleic acid detection assays (e.g., RNA Seq assays) described herein. Additionally, treatment of a patient suffering from a lysosomal storage disorder, such as Pompe disease, may manifest in improvements in a patient's muscle function (e.g., cardiac or skeletal muscle function) as well as improvements in muscle coordination.
As used herein, the term “Pompe disease” refers to the genetically inherited glycogen storage disorder that is caused by mutations of the GAA gene and is characterized by symptoms including mild to profound muscle weakness, hypotonia (diminished muscle tone), an enlarged liver, failure to gain weight and/or grow at the expected rate, trouble breathing, feeding problems, infections of the respiratory system, and/or problems with hearing. An exemplary wild-type human GAA amino acid sequence is provided in SEQ ID NO: 2, below.
As used herein, the term “vector” refers to a nucleic acid, e.g., DNA or RNA, that may function as a vehicle for the delivery of a gene of interest into a cell (e.g., a mammalian cell, such as a human cell), such as for purposes of replication and/or expression. Exemplary vectors useful in conjunction with the compositions and methods described herein are plasmids, DNA vectors, RNA vectors, virions, or another suitable replicon (e.g., viral vector). A variety of vectors have been developed for the delivery of polynucleotides encoding exogenous proteins into a prokaryotic or eukaryotic cell. Examples of such expression vectors are disclosed in, e.g., WO94/11026, the disclosure of which is incorporated herein by reference. Expression vectors described herein contain a polynucleotide sequence as well as, e.g., additional sequence elements used for the expression of proteins and/or the integration of these polynucleotide sequences into the genome of a mammalian cell. Certain vectors that can be used for the expression of transgenes described herein include plasmids that contain regulatory sequences, such as promoter and enhancer regions, which direct gene transcription. Other useful vectors for expression of transgenes contain polynucleotide sequences that enhance the rate of translation of these genes or improve the stability or nuclear export of the mRNA that results from gene transcription. These sequence elements include, e.g., 5′ and 3′ untranslated regions, an internal ribosomal entry site (IRES), and polyadenylation signal site to direct efficient transcription of the gene carried on the expression vector. The expression vectors described herein may also contain a polynucleotide encoding a marker for selection of cells that contain such a vector. Examples of a suitable marker include genes that encode resistance to antibiotics, such as ampicillin, chloramphenicol, kanamycin, or nourseothricin.
As used herein in the context of a therapeutic protein, such as GAA, the use of the protein name refers to the gene encoding the protein or the corresponding protein product, depending upon the context, as will be appreciated by one of skill in the art. The term “GAA” includes wild-type forms of the GAA gene or protein, as well as variants (e.g., splice variants, truncations, concatemers, and fusion constructs, among others) of wild-type GAA proteins that retain therapeutic activity of the wild-type GAA protein, as well as nucleic acids encoding the same. Examples of such variants are proteins having at least 70% sequence identity (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%, or 99.5% identity, or more) to an amino acid sequence of a wild-type GAA protein, such as SEQ ID NO: 2, below:
Similarly, as used herein in the context of a transcription regulatory element, the term “MCK promoter” refers to a wild-type MCK promoter, such as a wild-type human or murine MCK promoter, as well as variants (e.g., variants containing insertions, deletions, and/or substitutions of one or more nucleic acid residues) to the extent that the promoter retains the ability to induce expression of an operably linked gene in a muscle and/or neuronal cell. An exemplary MCK promoter that may be used in conjunction with the compositions and methods of the disclosure is shown in SEQ ID NO: 1, below:
The chemical terminology used herein is for the purpose of describing various aspects and embodiments of the disclosure and is not intended to be limiting.
In the following chemical definitions, a notation in which an integral number immediately follows an atomic symbol indicates the quantity of atoms of that element that are present in a particular chemical moiety. As will be understood, other atoms, such as hydrogen atoms, or substituent groups described herein, may be present, as necessary, to satisfy the valence of a particular atom. For example, an unsubstituted “C2 alkyl group” has the formula —CH2CH3. When used in conjunction with the groups defined herein, a reference to a number of carbon atoms includes the divalent carbon in acetal and ketal groups but does not include the carbonyl carbon in acyl, ester, carbonate, amide, or carbamate groups. A reference to a number of oxygen, nitrogen, or sulfur atoms in a heteroaryl group only includes those atoms that form a part of a heterocyclic ring.
As used herein, a phrase of the form “optionally substituted X” (e.g., optionally substituted alkyl) is intended to be equivalent to “X, wherein X is optionally substituted” (e.g., “alkyl, wherein the alkyl is optionally substituted”). It is not intended to mean that the feature “X” (e.g., alkyl) per se is optional. As described herein, certain compounds may contain one or more “optionally substituted” moieties. In general, the term “substituted”, whether preceded by the term “optionally” or not, means that one or more hydrogens of the designated moiety are replaced with a suitable substituent, such as any of the substituents or groups described herein. Unless otherwise indicated, an “optionally substituted” group may have a suitable substituent at each substitutable position of the group, and when more than one position in any given structure may be substituted with more than one substituent selected from a specified group, the substituent may be either the same or different at every position. Combinations of substituents that may be used in conjunction with the compounds of the disclosure are preferably those that result in the formation of stable or chemically feasible compounds. The term “stable,” as used herein, refers to compounds that are not substantially altered when subjected to conditions that allow for their production, detection, and, in certain embodiments, recovery, purification, and use for one or more of the purposes disclosed herein.
As used herein, the term “aliphatic” refers to a saturated or unsaturated, straight, branched, or cyclic hydrocarbon. The term “aliphatic” includes, but is not limited to, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, and cycloalkynyl moieties, and thus incorporates each of these definitions. In some embodiments, “aliphatic” is used to indicate those aliphatic groups having from 1 to 20 carbon atoms. The aliphatic chain may be, for example, mono-unsaturated, di-unsaturated, tri-unsaturated, or polyunsaturated, or alkynyl. Unsaturated aliphatic groups can be in a cis or trans configuration. In some embodiments, the aliphatic group contains from 1 to about 12 carbon atoms, such as from 1 to about 6 carbon atoms or from 1 to about 4 carbon atoms. In some embodiments, the aliphatic group contains from 1 to about 8 carbon atoms. In some embodiments, the aliphatic group is C1-C2, C1-C3, C1-C4, C1-C5, or C1-C6. The specified ranges used herein indicate an aliphatic group having each member of the range described as an independent species. For example, the term “C1-C6 aliphatic” as used herein indicates a straight or branched alkyl, alkenyl, or alkynyl group having from 1, 2, 3, 4, 5, or 6 carbon atoms and is intended to mean that each of these is described as an independent species. For example, the term “C1-C4 aliphatic” as used herein indicates a straight or branched alkyl, alkenyl, or alkynyl group having from 1, 2, 3, or 4 carbon atoms and is intended to mean that each of these is described as an independent species. In some embodiments, the aliphatic group is substituted with one or more functional groups that results in the formation of a stable moiety.
As used herein, the term “heteroaliphatic” refers to an aliphatic moiety that contains at least one heteroatom in its chain, such as an amine, carbonyl, carboxy, oxo, thio, phosphate, phosphonate, nitrogen, phosphorus, silicon, or boron atom in place of a carbon atom. In some embodiments, the heteroatom present is nitrogen. In some embodiments, the heteroatom present is oxygen. In some embodiments, the heteroatom present is sulfur. The term “heteroaliphatic” includes, but is not limited to, heteroalkyl, heteroalkenyl, heteroalkynyl, heterocycloalkyl, heterocycloalkenyl, and heterocycloalkynyl moieties.

Compounds of the disclosure may have one or more asymmetric carbon atoms and may exist in the form of optically pure enantiomers, mixtures of enantiomers (e.g., racemates), optically pure diastereoisomers, mixtures of diastereoisomers, diastereoisomeric racemates, or mixtures of diastereoisomeric racemates. The optically active forms can be obtained, for example, by resolution of the racemates, by asymmetric synthesis or asymmetric chromatography (chromatography with a chiral adsorbent or eluant). Accordingly, the compounds disclosed herein may exist in various stereoisomeric forms.
Stereoisomers are compounds that differ only in their spatial arrangement. Enantiomers are pairs of stereoisomers whose mirror images are not superimposable, most commonly because they contain an asymmetrically substituted carbon atom that acts as a chiral center. The term “enantiomer” means one of a pair of molecules that are mirror images of each other and are not superimposable. Diastereomers are stereoisomers that are not related as mirror images, most commonly because they contain two or more asymmetrically substituted carbon atoms and represent the configuration of substituents around one or more chiral carbon atoms.
Enantiomers of a compound can be prepared, for example, by separating an enantiomer from a racemate using one or more well-known techniques and methods, such as, for example, chiral chromatography and separation methods based thereon. The terms “racemate” and “racemic mixture” refer to a compound containing two enantiomers, wherein such mixtures exhibit no optical activity, i.e., they do not rotate the plane of polarized light. The term “geometric isomer” refers to isomers that differ in the orientation of substituent atoms in relationship to a carbon-carbon double bond, to a cycloalkyl ring, or to a bridged bicyclic system. Atoms (other than H) on each side of a carbon-carbon double bond may be in an E (substituents are on opposite sides of the carbon-carbon double bond) or Z (substituents are oriented on the same side of the carbon-carbon double bond) configuration. “R,” “S,” “S*,” “R*,” “E,” “Z,” “cis,” and “trans,” indicate configurations relative to the core molecule.
When the stereochemistry of a compound disclosed herein is named or depicted by structure, the named or depicted stereoisomer is greater than 50% by weight (e.g., at least 60%, 70%, 80%, 90%, 99%, or 99.9% by weight) relative to its other stereoisomers. For example, when a single enantiomer is named or depicted by structure, the depicted or named enantiomer is greater than 50% by weight (e.g., at least 60%, 70%, 80%, 90%, 99%, or 99.9% by weight) optically pure. Similarly, when a single diastereomer is named or depicted by structure, the depicted or named diastereomer is greater than 50% by weight (e.g., at least 60%, 70%, 80%, 90%, 99%, or 99.9% by weight) pure. Percent optical purity is the ratio of the weight of the enantiomer or over the weight of the enantiomer plus the weight of its optical isomer. Diastereomeric purity by weight is the ratio of the weight of one diastereomer or over the weight of all the diastereomers.
Additionally, when the stereochemistry of a compound disclosed herein is named or depicted by structure, the named or depicted stereoisomer is greater than 50% by mole fraction (e.g., at least 60%, 70%, 80%, 90%, 99%, or 99.9% by mole fraction) relative to its other stereoisomers. For example, when a single enantiomer is named or depicted by structure, the depicted or named enantiomer is greater than 50% by mole fraction (e.g., at least 60%, 70%, 80%, 90%, 99%, or 99.9% by mole fraction) relative to the other enantiomer. When a single diastereomer is named or depicted by structure, the depicted or named diastereomer is greater than 50% by mole fraction (e.g., at least 60%, 70%, 80%, 90%, 99%, or 99.9% by mole fraction) relative to the other diastereomer(s) of the indicated compound. For enantiomeric compounds, percent purity by mole fraction is calculated as the ratio of the molar quantity of the enantiomer of interest relative to the sum of the molar quantities of (i) the enantiomer of interest and (ii) the optical isomer. Similarly, for diastereomeric compounds, percent purity by moles fraction is calculated as the ratio of the molar quantity of the diastereomer of interest relative to the total molar quantities of all diastereomers present for the indicated compound.
When a disclosed compound is named or depicted by structure without indicating the stereochemistry, and the compound has at least one chiral center, it is to be understood that the name or structure encompasses either enantiomer of the compound free from the corresponding optical isomer, a racemic mixture of the compound, or mixtures enriched in one enantiomer relative to its corresponding optical isomer.
When a disclosed compound is named or depicted by structure without indicating the stereochemistry and has two or more chiral centers, it is to be understood that the name or structure encompasses a diastereomer free of other diastereomers, a number of diastereomers free from other diastereomeric pairs, mixtures of diastereomers, mixtures of diastereomeric pairs, mixtures of diastereomers in which one diastereomer is enriched relative to the other diastereomer(s), or mixtures of diastereomers in which one or more diastereomer is enriched relative to the other diastereomers. The present disclosure embraces all of these forms.

Pompe disease (also known as glycogen storage disease type II, or GSD II) is caused by deficiency of the lysosomal enzyme GAA. The disease is an inborn error of metabolism in which a GAA deficiency ultimately results in glycogen accumulation in all tissues, especially striated muscle cells. In addition, the effect of glycogen accumulation within the central nervous system and its effect on skeletal muscle function have been documented.
Three clinical forms of this disorder are known: infantile, juvenile, and adult. Infantile Pompe disease has its onset shortly after birth and presents with progressive muscular weakness and cardiac failure. Infantile forms of Pompe are also characterized by a rapid development of cardiomyopathy, and patients often display myopathy and neuropathy leading to death typically in the first year of life. Symptoms in adult and juvenile patients occur later in life, and skeletal muscles and neurons are primarily involved. Patients exhibiting this form of Pompe disease eventually die due to respiratory insufficiency. Patients may exceptionally survive for more than six decades. There is a correlation between the severity of the disease and the residual acid α-glucosidase activity, the activity being 10-20% of normal in late onset and less than 2% in early onset forms of the disease.

Viral genomes provide a rich source of vectors that can be used for the efficient delivery of a gene of interest (e.g., a transgene encoding GAA) into the genome of a target cell (e.g., a mammalian cell, such as a human cell). Viral genomes are particularly useful vectors for gene delivery because the polynucleotides contained within such genomes are typically incorporated into the genome of a target cell by generalized or specialized transduction. These processes occur as part of the natural viral replication cycle, and do not require added proteins or reagents to induce gene integration. Examples of viral vectors include AAV, retrovirus, adenovirus (e.g., Ad5, Ad26, Ad34, Ad35, and Ad48), parvovirus (e.g., adeno-associated viruses), coronavirus, negative strand RNA viruses such as orthomyxovirus (e.g., influenza virus), rhabdovirus (e.g., rabies and vesicular stomatitis virus), paramyxovirus (e.g., measles and Sendai), positive strand RNA viruses, such as picornavirus and alphavirus, and double stranded DNA viruses including adenovirus, herpesvirus (e.g., Herpes Simplex virus types 1 and 2, Epstein-Barr virus, cytomegalovirus), and poxvirus (e.g., vaccinia, modified vaccinia Ankara (MVA), fowlpox and canarypox). Other viruses useful for delivering polynucleotides encoding antibody light and heavy chains or antibody fragments of the invention include Norwalk virus, togavirus, flavivirus, reoviruses, papovavirus, hepadnavirus, and hepatitis virus, for example. Examples of retroviruses include avian leukosis-sarcoma, mammalian C-type, B-type viruses, D-type viruses, HTLV-BLV group, lentivirus, spumavirus
(Coffin, J. M., Retroviridae: The viruses and their replication, In Fundamental Virology, Third Edition, B. N. Fields, et al., Eds., Lippincott-Raven Publishers, Philadelphia, 1996). Other examples include murine leukemia viruses, murine sarcoma viruses, mouse mammary tumor virus, bovine leukemia virus, feline leukemia virus, feline sarcoma virus, avian leukemia virus, human T-cell leukemia virus, baboon endogenous virus, Gibbon ape leukemia virus, Mason Pfizer monkey virus, simian immunodeficiency virus, simian sarcoma virus, Rous sarcoma virus and lentiviruses. Other examples of vectors are described, for example, in U.S. Pat. No. 5,801,030, the disclosure of which is incorporated herein by reference as it pertains to viral vectors for use in gene therapy.
In some embodiments, nucleic acids of the compositions and methods described herein are incorporated into recombinant AAV (rAAV) vectors and/or virions to facilitate their introduction into a cell. rAAV vectors useful in the invention are recombinant nucleic acid constructs that include (1) a transgene to be expressed (e.g., a polynucleotide encoding a GAA protein) and (2) viral nucleic acids that facilitate integration and expression of the heterologous genes. The viral nucleic acids may include those sequences of AAV that are required in cis for replication and packaging (e.g., functional inverted terminal repeats (ITRs)) of the DNA into a virion. In typical applications, the transgene encodes GAA, which is useful for correcting a GAA mutation in patients suffering from glycogen storage disorders, such as Pompe disease. Such rAAV vectors may also contain marker or reporter genes. Useful rAAV vectors have one or more of the AAV wild type genes deleted in whole or in part but retain functional flanking ITR sequences. The AAV ITRs may be of any serotype (e.g., derived from serotype 2) suitable for a particular application. Methods for using rAAV vectors are described, for example, in Tal et al., J. Biomed. Sci. 7:279-291 (2000), and Monahan and Samulski, Gene Delivery 7:24-30 (2000), the disclosures of each of which are incorporated herein by reference as they pertain to AAV vectors for gene delivery.
The nucleic acids and vectors described herein can be incorporated into a rAAV virion to facilitate introduction of the nucleic acid or vector into a cell. The capsid proteins of AAV compose the exterior, non-nucleic acid portion of the virion and are encoded by the AAV cap gene. The cap gene encodes three viral coat proteins, VP1, VP2 and VP3, which are required for virion assembly. The construction of rAAV virions has been described, for example, in U.S. Pat. Nos. 5,173,414; 5,139,941; 5,863,541; 5,869,305; 6,057,152; and 6,376,237; as well as in Rabinowitz et al., J. Virol. 76:791-801 (2002) and Bowles et al., J. Virol. 77:423-432 (2003), the disclosures of each of which are incorporated herein by reference as they pertain to AAV vectors for gene delivery. rAAV virions useful in conjunction with the compositions and methods described herein include those derived from a variety of AAV serotypes including AAV 1, 2, 3, 4, 5, 6, 7, 8 and 9. For targeting muscle cells, rAAV virions that include at least one serotype 1 capsid protein may be particularly useful. rAAV virions that include at least one serotype 6 capsid protein may also be particularly useful, as serotype 6 capsid proteins are structurally similar to serotype 1 capsid proteins, and thus are expected to also result in high expression of GAA in muscle cells. rAAV serotype 9 has also been found to be an efficient transducer of muscle cells. Construction and use of AAV vectors and AAV proteins of different serotypes are described, for example, in Chao et al., Mol. Ther. 2:619-623 (2000); Davidson et al., Proc. Natl. Acad. Sci. USA 97:3428-3432 (2000); Xiao et al., J. Virol. 72:2224-2232 (1998); Halbert et al., J. Virol. 74:1524-1532 (2000); Halbert et al., J. Virol. 75:6615-6624 (2001); and Auricchio et al., Hum. Molec. Genet. 10:3075-3081 (2001), the disclosures of each of which are incorporated herein by reference as they pertain to AAV vectors for gene delivery.
Also useful in conjunction with the compositions and methods described herein are pseudotyped rAAV vectors. Pseudotyped vectors include AAV vectors of a given serotype (e.g., AAV9) pseudotyped with a capsid gene derived from a serotype other than the given serotype (e.g., AAV1, AAV2, AAV3, AAV4, AAV5, AAV6, AAV7, AAV8, etc.). For example, a representative pseudotyped vector is an AAV8 vector encoding a therapeutic protein pseudotyped with a capsid gene derived from AAV serotype 2. Techniques involving the construction and use of pseudotyped rAAV virions are known in the art and are described, for example, in Duan et al., J. Virol. 75:7662-7671 (2001); Halbert et al., J. Virol. 74:1524-1532 (2000); Zolotukhin et al., Methods, 28:158-167 (2002); and Auricchio et al., Hum. Molec. Genet., 10:3075-3081 (2001).
AAV virions that have mutations within the virion capsid may be used to infect particular cell types more effectively than non-mutated capsid virions. For example, suitable AAV mutants may have ligand insertion mutations for the facilitation of targeting AAV to specific cell types. The construction and characterization of AAV capsid mutants including insertion mutants, alanine screening mutants, and epitope tag mutants are described in Wu et al., J. Virol. 74:8635-45 (2000). Other rAAV virions that can be used in methods of the invention include those capsid hybrids that are generated by molecular breeding of viruses as well as by exon shuffling. See, e.g., Soong et al., Nat. Genet., 25:436-439 (2000) and Kolman and Stemmer, Nat. Biotechnol. 19:423-428 (2001).
Techniques that can be used to introduce a transgene, such as a GAA transgene described herein, into a target cell are known in the art. For example, electroporation can be used to permeabilize mammalian cells (e.g., human target cells) by the application of an electrostatic potential to the cell of interest. Mammalian cells, such as human cells, subjected to an external electric field in this manner are subsequently predisposed to the uptake of exogenous nucleic acids (e.g., nucleic acids capable of expression in e.g., neurons, glial cells, or non-neural cells, such as colon and kidney cells). Electroporation of mammalian cells is described in detail, e.g., in Chu et al., Nucleic Acids Research 15:1311 (1987), the disclosure of which is incorporated herein by reference. A similar technique, NUCLEOFECTION™, utilizes an applied electric field to stimulate the uptake of exogenous polynucleotides into the nucleus of a eukaryotic cell. NUCLEOFECTION™ and protocols useful for performing this technique are described in detail, e.g., in Distler et al., Experimental Dermatology 14:315 (2005), as well as in US 2010/0317114, the disclosures of each of which are incorporated herein by reference.
An additional technique useful for the transfection of target cells is the squeeze-poration methodology. This technique induces the rapid mechanical deformation of cells to stimulate the uptake of exogenous DNA through membranous pores that form in response to the applied stress. This technology is advantageous in that a vector is not required for delivery of nucleic acids into a cell, such as a human target cell. Squeeze-poration is described in detail, e.g., in Sharei et al., J. Vis. Exp. 81:e50980 (2013), the disclosure of which is incorporated herein by reference.
Lipofection represents another technique useful for transfection of target cells. This method involves the loading of nucleic acids into a liposome, which often presents cationic functional groups, such as quaternary or protonated amines, towards the liposome exterior. This promotes electrostatic interactions between the liposome and a cell due to the anionic nature of the cell membrane, which ultimately leads to uptake of the exogenous nucleic acids, for example, by direct fusion of the liposome with the cell membrane or by endocytosis of the complex. Lipofection is described in detail, for example, in U.S. Pat. No. 7,442,386, the disclosure of which is incorporated herein by reference. Similar techniques that exploit ionic interactions with the cell membrane to provoke the uptake of foreign nucleic acids are contacting a cell with a cationic polymer-nucleic acid complex. Exemplary cationic molecules that associate with polynucleotides so as to impart a positive charge favorable for interaction with the cell membrane are activated dendrimers (described, e.g., in Dennig, Top Curr Chem. 228:227 (2003), the disclosure of which is incorporated herein by reference) polyethylenimine, and DEAE-dextran, the use of which as a transfection agent is described in detail, for example, in Gulick et al., Curr Protoc Mol Biol. 40:1:9.2:9.2.1 (1997), the disclosure of which is incorporated herein by reference.
Another useful tool for inducing the uptake of exogenous nucleic acids by target cells is laserfection, also called optical transfection, a technique that involves exposing a cell to electromagnetic radiation of a particular wavelength to gently permeabilize the cells and allow polynucleotides to penetrate the cell membrane. The bioactivity of this technique is like, and in some cases found superior to, electroporation.
Impalefection is another technique that can be used to deliver genetic material to target cells. It relies on the use of nanomaterials, such as carbon nanofibers, carbon nanotubes, and nanowires. Needle-like nanostructures are synthesized perpendicular to the surface of a substrate. DNA containing the gene, intended for intracellular delivery, is attached to the nanostructure surface. A chip with arrays of these needles is then pressed against cells or tissue. Cells that are impaled by nanostructures can express the delivered gene(s). An example of this technique is described in Shalek et al., PNAS 107:25 1870 (2010), the disclosure of which is incorporated herein by reference.
MAGNETOFECTION™ can also be used to deliver nucleic acids to target cells. The principle of MAGNETOFECTION™ is to associate nucleic acids with cationic magnetic nanoparticles. The magnetic nanoparticles are made of iron oxide, which is fully biodegradable, and coated with specific cationic proprietary molecules varying upon the applications. Their association with the gene vectors (DNA, siRNA, viral vector, etc.) is achieved by salt-induced colloidal aggregation and electrostatic interaction. The magnetic particles are then concentrated on the target cells by the influence of an external magnetic field generated by magnets. This technique is described in detail in Scherer et al., Gene Ther. 9:102 (2002), the disclosure of which is incorporated herein by reference. Magnetic beads are another tool that can be used to transfect target cells in a mild and efficient manner, as this methodology utilizes an applied magnetic field to direct the uptake of nucleic acids. This technology is described in detail, for example, in US2010/0227406, the disclosure of which is incorporated herein by reference.
Another useful tool for inducing the uptake of exogenous nucleic acids by target cells is sonoporation, a technique that involves the use of sound (typically ultrasonic frequencies) for modifying the permeability of the cell plasma membrane permeabilize the cells and allow polynucleotides to penetrate the cell membrane. This technique is described in detail, e.g., in Rhodes et al., Methods Cell Biol. 82:309 (2007), the disclosure of which is incorporated herein by reference.
Microvesicles represent another potential vehicle that can be used to modify the genome of a target cell according to the methods described herein. For example, microvesicles that have been induced by the co-overexpression of the glycoprotein VSV-G with, e.g., a genome-modifying protein, such as a nuclease, can be used to efficiently deliver proteins into a cell that subsequently catalyze the site-specific cleavage of an endogenous polynucleotide sequence to prepare the genome of the cell for the covalent incorporation of a polynucleotide of interest, such as a gene or regulatory sequence. The use of such vesicles, also referred to as Gesicles, for the genetic modification of eukaryotic cells is described in detail, e.g., in Quinn et al., Genetic Modification of Target Cells by Direct Delivery of Active Protein [abstract]. In: Methylation changes in early embryonic genes in cancer [abstract], in: Proceedings of the 18th Annual Meeting of the American Society of Gene and Cell Therapy; 2015 May 13, Abstract No. 122.
In addition to the above, a variety of tools have been developed that can be used for the incorporation of a gene of interest into a target cell, such as a human cell. One such method that can be used for incorporating polynucleotides encoding target genes into target cells involves the use of transposons. Transposons are polynucleotides that encode transposase enzymes and contain a polynucleotide sequence or gene of interest flanked by 5′ and 3′ excision sites. Once a transposon has been delivered into a cell, expression of the transposase gene commences and results in active enzymes that cleave the gene of interest from the transposon. This activity is mediated by the site-specific recognition of transposon excision sites by the transposase. In some instances, these excision sites may be terminal repeats or inverted terminal repeats. Once excised from the transposon, the gene of interest can be integrated into the genome of a mammalian cell by transposase-catalyzed cleavage of similar excision sites that exist within the nuclear genome of the cell. This allows the gene of interest to be inserted into the cleaved nuclear DNA at the complementary excision sites, and subsequent covalent ligation of the phosphodiester bonds that join the gene of interest to the DNA of the mammalian cell genome completes the incorporation process. In certain cases, the transposon may be a retrotransposon, such that the gene encoding the target gene is first transcribed to an RNA product and then reverse-transcribed to DNA before incorporation in the mammalian cell genome. Exemplary transposon systems are the piggybac transposon (described in detail in, e.g., WO 2010/085699) and the sleeping beauty transposon (described in detail in, e.g., US 2005/0112764), the disclosures of each of which are incorporated herein by reference as they pertain to transposons for use in gene delivery to a cell of interest.
Another tool for the integration of target genes into the genome of a target cell is the clustered regularly interspaced short palindromic repeats (CRISPR)/Cas system, a system that originally evolved as an adaptive defense mechanism in bacteria and archaea against viral infection. The CRISPR/Cas system includes palindromic repeat sequences within plasmid DNA and an associated Cas9 nuclease. This ensemble of DNA and protein directs site specific DNA cleavage of a target sequence by first incorporating foreign DNA into CRISPR loci. Polynucleotides containing these foreign sequences and the repeat-spacer elements of the CRISPR locus are in turn transcribed in a host cell to create a guide RNA, which can subsequently anneal to a target sequence and localize the Cas9 nuclease to this site. In this manner, highly site-specific cas9-mediated DNA cleavage can be engendered in a foreign polynucleotide because the interaction that brings cas9 within close proximity of the target DNA molecule is governed by RNA:DNA hybridization. As a result, one can design a CRISPR/Cas system to cleave any target DNA molecule of interest. This technique has been exploited to edit eukaryotic genomes (Hwang et al., Nature Biotechnology 31:227 (2013)) and can be used as an efficient means of site-specifically editing target cell genomes in order to cleave DNA prior to the incorporation of a gene encoding a target gene. The use of CRISPR/Cas to modulate gene expression has been described in, for example, U.S. Pat. No. 8,697,359, the disclosure of which is incorporated herein by reference as it pertains to the use of the CRISPR/Cas system for genome editing. Alternative methods for site-specifically cleaving genomic DNA prior to the incorporation of a gene of interest in a target cell include the use of zinc finger nucleases (ZFNs) and transcription activator-like effector nucleases (TALENs). Unlike the CRISPR/Cas system, these enzymes do not contain a guiding polynucleotide to localize to a specific target sequence. Target specificity is instead controlled by DNA binding domains within these enzymes. The use of ZFNs and TALENs in genome editing applications is described, e.g., in Urnov et al., Nat. Rev. Genet. 11:636 (2010); and in Joung et al., Nat. Rev. Mol. Cell Biol. 14:49 (2013), the disclosure of each of which are incorporated herein by reference as they pertain to compositions and methods for genome editing.
Additional genome editing techniques that can be used to incorporate polynucleotides encoding target genes into the genome of a target cell include the use of ARCUS™ meganucleases that can be rationally designed to site-specifically cleave genomic DNA. The use of these enzymes for the incorporation of genes encoding target genes into the genome of a mammalian cell is advantageous in view of the defined structure-activity relationships that have been established for such enzymes. Single chain meganucleases can be modified at certain amino acid positions to create nucleases that selectively cleave DNA at desired locations, enabling the site-specific incorporation of a target gene into the nuclear DNA of a target cell. These single-chain nucleases have been described extensively in, for example, U.S. Pat. Nos. 8,021,867 and 8,445,251, the disclosures of each of which are incorporated herein by reference as they pertain to compositions and methods for genome editing.
Using the compositions and methods of the disclosure, a patient having a glycogen storage disorder (e.g., Pompe disease) may be administered an AAV vector containing a transgene encoding GAA (e.g., the viral vector) in an amount of from about 1×1013 vg/kg to about 3×1014 vg/kg.

The gene therapy agents described herein may contain a transgene, such as a transgene encoding GAA and may be incorporated into a vehicle for administration into a patient, such as a human patient suffering from a glycogen storage disorder (for example, Pompe disease). Pharmaceutical compositions containing vectors, such as viral vectors, that contain the transcription regulatory elements (e.g., a MCK promoter) described herein operably linked to a therapeutic transgene can be prepared using methods known in the art. For example, such compositions can be prepared using, e.g., physiologically acceptable carriers, excipients or stabilizers (Remington's Pharmaceutical Sciences 16th edition, Osol, A. Ed. (1980); incorporated herein by reference), and in a desired form, e.g., in the form of lyophilized formulations or aqueous solutions.
Viral vectors, such as AAV vectors and others described herein, containing the transcription regulatory element operably linked to a therapeutic transgene may be administered to a patient (e.g., a human patient) by a variety of routes of administration. The route of administration may vary, for example, with the onset and severity of disease, and may include, e.g., intradermal, transdermal, parenteral, intravenous, intramuscular, intranasal, subcutaneous, percutaneous, intratracheal, intraperitoneal, intraarterial, intravascular, inhalation, perfusion, lavage, and oral administration. Intravascular administration includes delivery into the vasculature of a patient. In some embodiments, the administration is into a vessel considered to be a vein (intravenous), and in some administration, the administration is into a vessel considered to be an artery (intraarterial). Veins include, but are not limited to, the internal jugular vein, a peripheral vein, a coronary vein, a hepatic vein, the portal vein, great saphenous vein, the pulmonary vein, superior vena cava, inferior vena cava, a gastric vein, a splenic vein, inferior mesenteric vein, superior mesenteric vein, cephalic vein, and/or femoral vein. Arteries include, but are not limited to, coronary artery, pulmonary artery, brachial artery, internal carotid artery, aortic arch, femoral artery, peripheral artery, and/or ciliary artery. It is contemplated that delivery may be through or to an arteriole or capillary.
Mixtures of the nucleic acids and viral vectors described herein may be prepared in water suitably mixed with one or more excipients, carriers, or diluents. Dispersions may also be prepared in glycerol, liquid polyethylene glycols, and mixtures thereof and in oils. Under ordinary conditions of storage and use, these preparations may contain a preservative to prevent the growth of microorganisms. The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions (described in U.S. Pat. No. 5,466,468, the disclosure of which is incorporated herein by reference). In any case the formulation may be sterile and may be fluid to the extent that easy syringability exists. Formulations may be stable under the conditions of manufacture and storage and may be preserved against the contaminating action of microorganisms, such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol, and liquid polyethylene glycol, and the like), suitable mixtures thereof, and/or vegetable oils. Proper fluidity may be maintained, for example, using a coating, such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. The prevention of the action of microorganisms can be brought about by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars or sodium chloride. Prolonged absorption of the injectable compositions can be brought about by the use in the compositions of agents delaying absorption, for example, aluminum monostearate and gelatin.
For example, a solution containing a pharmaceutical composition described herein may be suitably buffered, if necessary, and the liquid diluent first rendered isotonic with sufficient saline or glucose. These particular aqueous solutions are especially suitable for intravenous, intramuscular, subcutaneous, and intraperitoneal administration. In this connection, sterile aqueous media that can be employed will be known to those of skill in the art in light of the present disclosure. For example, one dosage may be dissolved in 1 mL of isotonic NaCl solution and either added to 1000 mL of hypodermoclysis fluid or injected at the proposed site of infusion. Some variation in dosage will necessarily occur depending on the condition of the subject being treated. The person responsible for administration will, in any event, determine the appropriate dose for the individual subject. Moreover, for human administration, preparations may meet sterility, pyrogenicity, general safety, and purity standards as required by FDA Office of Biologics standards.

The following examples are put forth to provide those of ordinary skill in the art with a description of how the compositions and methods described herein may be used and evaluated and are intended to be purely exemplary of the invention and are not intended to limit the scope of what the inventors regard as their invention.
The objective of this study was to examine the potential adverse effects of an AAV8 vector containing a GAA transgene operably linked to a muscle creatine kinase (MCK) promoter in human patients having a glycogen storage disorder (e.g., Pompe disease). Pompe disease is a monogenic, autosomal recessive disease caused by mutations in the gene encoding the lysosomal enzyme GAA, which normally degrades lysosomal glycogen. Deficiency in functional GAA leads to accumulation of glycogen in the lysosomes of all cells in the body, with pathophysiological damage to skeletal and cardiac muscles. Pompe disease spans a continuum of disease severity in which age of disease onset, degree of myopathy and extent of organ involvement correlate with residual enzyme activity. Late-onset Pompe disease (LOPD) typically manifests as slowly progressive limb girdle myopathy with proximal muscle weakness and respiratory impairment. With disease progression LOPD can eventually result in impaired mobility and respiratory insufficiency requiring wheelchair use and a full-time ventilator.
Four patients having Pompe disease and greater than or equal to 18 years old were administered a recombinant AAV vector serotype 8 expressing the recombinant human acid alpha glucosidase (rhGAA) gene specifically in the muscle, which is currently under clinical development for the treatment of LOPD. FORTIS (NCT04174105) is an ongoing multicenter, open-label, ascending dose Phase I/II first-in-human clinical trial to determine if the vector is safe and tolerable in adult subjects with LOPD. Subjects enrolled in FORTIS receive a one-time peripheral intravenous infusion of the vector described herein, followed by one year of frequent monitoring of clinical and biochemical endpoints including GAA activity and protein level in muscle and four years of long-term safety monitoring (
Primary endpoints in the study include monitoring the frequency of adverse events, serious adverse events and changes from baseline in relevant clinical tests (e.g., clinical chemistry, hematology, coagulation parameters, and urinalysis), elevations in cardiac enzymes, and potential immune responses. Secondary assessments include change from baseline in GAA protein expression and enzyme activity in muscle (Week 12; see e.g.,
A summary of the participants and doses administered are presented in Table 1.
These interim data focus on safety findings for Cohort 1 and Cohort 2.
Four adult subjects with LOPD have received an AAV described herein, with two subjects dosed with the clinical starting dose of 3×1013 vg/kg and two subjects dosed with the escalated dose of 6×1013 vg/kg. The infusions were generally well-tolerated, and no serious adverse events (SAEs) related to the study drug were reported as of the data cut-off for this analysis. Since the data cut-off, one Treatment-Emergent Adverse Event (TEAE), tingling hands and feet, has been reclassified as peripheral sensory neuropathy and designated as a SAE. Grade 1 TEAEs were defined as mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; no intervention indicated. Grade 2 TEAEs were defined as moderate; minimal, local or noninvasive intervention indicated. Grade 3 TEAEs were defined as severe or medically significant but not immediately life threatening; hospitalization or prolongation of hospitalization indicated; disabling. Grade 4 TEAEs were defined as life-threatening consequences; urgent intervention indicated, while Grade 5 TEAEs were defined as death related to AE. Subjects dosed in the study experienced TEAEs, defined as adverse effects (AEs) that occurred after administration of the AAV encoding GAA described herein. Table 2 presents the most frequent TEAEs that were reported in the subjects. TEAEs occurring at a severity of Grade 3 in 1 subject included transaminasemia-related adverse events, including an increase in alanine aminotransferase (ALT). TEAEs occurring at a severity of Grade 2 in 3 subjects included transaminasemia-related adverse events, including an increase in alanine aminotransferase (ALT) and aspartate aminotransferase (AST), as well as nausea. All other observed TEAEs were Grade 1 TEAEs and considered to be unrelated to study treatment. There were no AAV infusion-related AEs, and no deaths have been reported.
Safety monitoring for thrombotic microangiopathy (TMA) was conducted, and we found that there was no evidence of TMA in any of the participants (
To evaluate cardiac safety, levels troponin I, troponin T, and B-type natriuretic peptide were monitored (
To evaluate biomarkers of disease, we measured blood creatine kinase and urine Hex4. Creatine kinase (CK) is a sensitive marker for muscle disease, although it is nonspecific for Pompe disease. Blood CK levels are elevated in most individuals with LOPD (e.g., 1.5 to 15×ULN) (e.g., normal range 38-174 U/L in men; 90-140 U/L in women). Urine Hex4 is often elevated in glycogen storage diseases and muscle disorders; although non-specific as a diagnostic test for Pompe disease, it can be useful for monitoring response to treatment (e.g., Hex4 concentrations are measured relative to creatine and reported as a normalized Hex4 in mmol/mol creatinine; normally <4). All four participants showed stabilization of biomarkers of disease, even after withdrawal of enzyme replacement therapy in participants 2001 and 2003 (
To evaluate vector shedding, urine and saliva samples were taken. In the participants dosed, vector shedding in urine and saliva peaked in the first 2 weeks after infusion of an AAV described herein (
To evaluate the humoral immune response to a pseudotyped AAV2/8 vector including a nucleic acid sequence encoding an GAA gene operably linked to a MCK promoter, described herein, an enzyme-linked immunosorbent assay (ELISA) was performed using an antibody titer test against anti-GAA total or anti-AAV8 neutralizing antibodies, respectively (
To confirm transduction of the AAV in target tissues, a muscle biopsy was taken, and a vector copy number assay was performed. Both participants in Cohort 1 and both participants in Cohort 2 showed transduction of the gene of interest in the muscle by 12 weeks post infusion of the AAV (
Liver transaminases and bilirubin were also monitored over time for patients 2002, 2003, and 2009 (
In summary, we found that a combination therapy, including administration of a viral vector including a transgene encoding GAA and an anti-transaminitis agent (e.g., a corticosteroid, such as prednisolone), can serve as a prophylactic treatment for liver syndromes associated with the existing gene therapy approaches involving the delivery of GAA to patients in need thereof (e.g., patients with Pompe disease).
Using the compositions and methods of the disclosure, a patient (e.g., one year old or older) having LOPD may be administered the viral vector, for example, in a dose of from about 1×1013 vg/kg to about 3×1014 vg/kg (e.g., from about 1×1013 vg/kg to about 6×1013 vg/kg, from about 1×1013 vg/kg to about 5×1013 vg/kg, from about 1×1013 vg/kg to about 4×1013 vg/kg, from about 1×1013 vg/kg to about 3×1013 vg/kg, from about 2×1013 vg/kg to about 6×1013 vg/kg, from about 2×1013 vg/kg to about 5×1013 vg/kg, or from about 2×1013 vg/kg to about 4×1013 vg/kg) and an anti-transaminitis agent (e.g., prednisolone). The anti-transaminitis agent may be, for example, administered as doses of about 0.1 mg/kg/dose to about 2 mg/kg/dose and by way of a unit dosage form including 5 mg, 10 mg, 15, mg, or 30 mg and/or from 1 mg/day to about 120 mg/day.

Using the compositions and methods of the disclosure, a patient having LOPD that is greater than about one year old may be administered a pseudotyped AAV2/8 vector including a nucleic acid sequence encoding an GAA gene operably linked to a MCK promoter (e.g., the viral vector), for example, in a dose of from about 1×1013 vg/kg to about 3×1014 vg/kg (e.g., from about 1×1013 vg/kg to about 6×1013 vg/kg, from about 1×1013 vg/kg to about 5×1013 vg/kg, from about 1×1013 vg/kg to about 4×1013 vg/kg, from about 1×1013 vg/kg to about 3×1013 vg/kg, from about 2×1013 vg/kg to about 6×1013 vg/kg, from about 2×1013 vg/kg to about 5×1013 vg/kg, or from about 2×1013 vg/kg to about 4×1013 vg/kg). Afterwards, the patient may be monitored for the development of transaminitis, and if the patient is determined to exhibit transaminitis or one or more symptoms thereof, the patient is administered an anti-transaminitis agent (e.g., prednisolone). The anti-transaminitis agent may be, for example, administered in one or doses of about 0.1 mg/kg/dose to about 2 mg/kg/dose and by way of a unit dosage form including 5 mg, 10 mg, 15, mg, or 30 mg and/or from 1 mg/day to about 120 mg/day.
Upon administering the pseudotyped AAV2/8 vector including a nucleic acid sequence encoding an GAA gene operably linked to a MCK promoter (e.g., the viral vector) to the patient, the patient displays a change from baseline in quantitative analysis of GAA expression in a muscle biopsy. For example, the patient displays the change from baseline in quantitative analysis of GAA expression in a muscle biopsy by about 24 weeks (e.g., by about 20 weeks, 16 weeks, 12 weeks, 8 weeks, or 4 weeks) after administration of the pseudotyped AAV2/8 vector including a nucleic acid sequence encoding an GAA gene operably linked to a MCK promoter (e.g., the viral vector) to the patient. Upon administering the pseudotyped AAV2/8 vector including a nucleic acid sequence encoding an GAA gene operably linked to a MCK promoter (e.g., the viral vector) to the patient, the patient displays a reduction of glycogen accumulation in muscle tissue and/or in neuronal tissue by about 24 weeks (e.g., by about 20 weeks, 16 weeks, 12 weeks, 8 weeks, or 4 weeks) after administration of the pseudotyped AAV2/8 vector including a nucleic acid sequence encoding an GAA gene operably linked to a MCK promoter (e.g., the viral vector) to the patient.

Afterwards, the patient may be monitored for the development of transaminitis, and if the patient is determined to exhibit transaminitis or one or more symptoms thereof, the patient is administered an anti-transaminitis agent (e.g., prednisolone), for example, in one or doses of about 0.1 mg/kg/dose to about 2 mg/kg/dose and by way of a unit dosage form including 5 mg, 10 mg, 15, mg, or 30 mg and/or from 1 mg/day to about 120 mg/day.
Upon administering the viral vector to the patient, the patient displays a change from baseline in quantitative analysis of GAA expression in a muscle biopsy. For example, the patient displays the change from baseline in quantitative analysis of GAA expression in a muscle biopsy by about 24 weeks (e.g., by about 20 weeks, 16 weeks, 12 weeks, 8 weeks, or 4 weeks) after administration of the viral vector to the patient. For example, the change from baseline in quantitative analysis of GAA expression in a muscle biopsy persists for at least 48 weeks after administration of the viral vector to the patient. Upon administering the viral vector to the patient, the patient displays pulmonary function improvement by about 24 weeks (e.g., by about 20 weeks, 16 weeks, 12 weeks, 8 weeks, or 4 weeks) after administration of the viral vector to the patient.
