FIELD OF INVENTION

The present invention relates generally to the field of viral vectors and systems for the delivery of genes and other therapeutic, diagnostic, or research uses. More specifically, embodiments of the present invention relate to non-integrating viral vectors and systems for the delivery of genes and other therapeutic, diagnostic, or research uses.

BACKGROUND TO THE INVENTION

Viral vectors have been used to transduce genes and other therapeutic nucleic acid constructs into target cells owing to their specific virus envelope-host cell receptor interactions and viral mechanisms for gene expression. As a result, viral vectors have been used as vehicles for the transfer of genes into many different cell types including, but not limited to, isolated tissue samples, tissue targets in situ and cultured cell lines. The ability to both introduce and express foreign genes in a cell is useful for the study of gene expression and the elucidation of cell lineages and pathways as well as providing the potential for therapeutic interventions such as gene therapy and various types of immunotherapy.

Several viral systems including lentivirus murine retrovirus, adenovirus, and adeno- associated virus have been proposed as potential therapeutic gene transfer vectors. However, many hurdles have prevented robust utilization of these as approved therapeutics. Research and development hurdles include, but are not limited to, stability and control of expression, genome packaging capacity, and construct-dependent vector stability. In addition, in vivo application of viral vectors can be limited by host immune responses against viral structural proteins and/or transduced gene products, which can result in deleterious anti-vector immunological effects. Researchers have attempted to find stable expression systems as a way of overcoming some of these hurdles. One approach utilizes recombinant polypeptides or gene regulatory molecules, including small RNA, in such expression systems. These systems employ chromosomal integration of a transduced retrovirus genome, or at least a portion thereof, into the genome of the host cell. An important limitation with these approaches is that the sites of gene integration are generally random, and the number and ratio of genes integrating at any particular site are often unpredictable. Thus, vectors that rely on chromosomal integration result in permanent maintenance of the recombinant gene that may exceed the therapeutic interval, and plasmid or other non-replicating DNA is poorly controlled and may decay before completing a desired therapeutic interval.

Another approach is the use of a transient expression system. Under a transient expression system, the expression of the gene of interest is based on non-integrated plasmids, and hence the expression is typically lost as the cell undergoes subsequent division or the plasmid vectors are destroyed by endogenous nucleases. Accordingly, transient gene expression systems typically do not lead to sufficient expression over time and typically require repeated treatments, which are generally understood to be undesirable features.

DETAILED DESCRIPTION

Disclosed herein is a stable viral delivery system and methods. In various aspects, the delivery system includes a transient expression system. According to one aspect, the delivery system is non-integrating. In another aspect the delivery system is both non-integrating and transient.

In further aspects, non-integrating, episomally replicating viral vectors (e.g., lentiviral vectors) and methods of using the same are provided. Episomally replicating vectors of the present invention can contain viral components from viruses like Papovaviridae (e.g., bovine papillomavirus or BPV) or Herpes viridae (e.g., Epstein Barr Virus or EBV) or Hepadnaviridae (e.g., Hepatitis B Virus or HBV). Episomal replicating vectors derived from these viruses may contain a replication origin and at least one viral trans-acting factor, e.g., an initiator protein, such as El for BPV and EBNA-1 for EBV or HBV polymerase or terminus binding protein of Adenovirus. The process of episomal replication typically incorporates both host cell replication machinery and viral trans-acting factors.

By using heterogeneous viral origins of replication, novel vectors can be engineered with an "off switch for expression of viral proteins required to recognize the origin of replication. Switching off DNA replication will cause therapeutic DNA levels to dramatically drop over time. Without wishing to be bound by any particular theory, it is believed that the non-replicating DNA simply degrades, such as by nuclease activity and as the host cell undergoes natural apoptosis (cell death) events over time. Eventually such non-replicating DNA may be non-detectible and completely or nearly cleared from the patient over time.

The disclosed systems and methods include reducing or preventing toxicity and toxic effects from over-expression or prolonged expression of transduced genes. Eliminating the gene once DNA replication ceases prevents unwanted gene expression or knockdown of host gene expression in the future. Likewise, combining the benefits of episomal replication into a heterogeneous viral system provides for a platform that can safely and efficiently transduce genes of interest into a variety of cell types.

Papillomavirus

Papillomaviruses replicate primarily as episomes in mammalian cells. Action of the viral El protein, which functions as a DNA helicase, on the viral origin of DNA replication (ori) drives the production of hundreds to thousands of DNA copies per cells depending on differentiation status of infected epithelial cells. Attempts have been made to develop papillomavirus-based gene delivery systems using what became known as "shuttle plasmids." With a bacterial origin of DNA replication to allow production of DNA in E. coli and a papillomavirus ori to allow episomal replication in mammalian cells, a number of studies have been performed to demonstrate safety and durability of gene expression. In most cases, the ori came from bovine papillomavirus.

Papillomaviruses have evolved to infect epidermal and epithelial cells. As infected cells differentiate from basal to luminal surfaces, papillomaviruses increase DNA replication and copy number becomes very high until a tremendous dose of virus is released at the lumenal surface. This makes papillomaviruses highly contagious as is apparent from human papillomavirus. The surge in copy number is due primarily to host factors. However, this feature of papillomavirus can be exploited to target transient gene therapy to epidermal and epithelial surfaces. Certain features of papillomavirus are used in accordance with various aspects and embodiments of the present invention for driving expression and replication of an episomal vector, as well as targeting expression of the vector to specific cell types.

Epstein Barr Virus (EBV) Epstein-Barr virus (EBV), also known as human herpesvirus 4, is a member of the herpes virus family. It is one of the most common human viruses, and most people become infected with EBV at some point in their lives.

EBV is a double-stranded DNA virus that contains approximately 85 genes; EBV is known to infect B cells and epithelial cells. EBV is capable of both lytic and latent replication, the latter of which results in a circularized version of the EBV genome translocating to the host cell nucleus where it may be replicated by host cell DNA polymerases.

EBV can undergo latent replication via at least three distinct pathways, but each one involves the expression of Epstein-Barr virus nuclear antigen 1 (EBNA-1), a protein that binds the episomal replication origin and mediates partitioning of the episome during division of the host cell. EBNA-1 plays an integral role in EBV gene regulation, replication, and episomal maintenance.

Certain features of EBV are used in accordance with various aspects and embodiments of the present invention.

Hepatitis B virus (HBV) Hepatitis B virus (HBV) is a member of the hepadnavirus family. It is a common human virus associated with progressive liver fibrosis, hepatitis and hepatocellular carcinoma.

HBV is a double stranded DNA virus that replicates through an RNA intermediate and depends on a viral polymerase. Stable maintenance of HBV in liver cells is due to the presence of covalently-closed viral DNA circular forms that are difficult to eradicate.

Thus, certain features of HBV are used in accordance with various aspects and embodiments of the present invention.

Retrovirus

Retrovirus is a virus family characterized by encoding a reverse transcriptase capable of generating DNA copies from RNA templates and integration of proviruses into the host cell chromosome. Lentivirus is a genus of retroviruses that can deliver a significant amount of viral nucleic acid into a host cell. Lentiviruses are characterized as having a unique ability to infect/transduce non-dividing cells, and following transduction, lentiviruses integrate their nucleic acid into the host cell's chromosomes.

Infectious lentiviruses have three main genes coding for the virulence proteins gag, pol, and env, and two regulatory genes including tat and rev. Depending on the specific serotype and virus, there may be additional accessory genes that code for proteins involved in regulation, synthesis, and/or processing viral nucleic acids and other replicative functions including counteracting innate cellular defenses against lentivirus infection.

Lentiviruses contain long terminal repeat (LTR) regions, which may be approximately 600 nt long. LTRs may be segmented into U3, R, and U5 regions. LTRs can mediate integration of retroviral DNA into the host chromosome via the action of integrase. Alternatively, without functioning integrase, the LTRs may be used to circularize the viral nucleic acid.

Viral proteins involved in early stages of lentivirus replication include reverse transcriptase and integrase. Reverse transcriptase is a virally encoded, RNA-dependent DNA polymerase. The enzyme uses a viral RNA genome as a template for the synthesis of a complementary DNA copy. Reverse transcriptase also has RNaseH activity for the destruction of the RNA-template that is necessary to DNA second strand synthesis to complete production of the double-stranded DNA ready for integration. Integrase binds both the viral cDNA generated by reverse transcriptase and the host DNA. Integrase processes the LTR before inserting the viral genome into the host DNA. Tat acts as a trans-activator during transcription to enhance the initiation and elongation of RNA copies made from viral DNA. The rev responsive element acts post-transcriptionally, regulating mRNA splicing and transport to the cytoplasm.

Certain features of retroviruses, including lentiviruses, are used in accordance with various aspects and embodiments of the present invention.

Vector-in- Vector System

A novel vector-in-vector (VIV) system is provided that can precisely regulate the delivery and expression of genes by combining desirable features from various viral species. Many viral vectors, including lentivirus (LV) platforms, may be used. Lentiviral transduction, like most other forms of stable transduction, results in chromosomal integration of the LV payload (e.g., gene of interest). In accordance with various aspects, chromosomal integration is abolished through selective mutations that inactivate the viral integrase gene. The papillomavirus ori plus El protein, or the EBV ori plus EBNA-1 or the Hepadnavirus termini plus viral polymerase are used herein, as part of the genetic cargo of a heterologous virus that would not ordinarily be able to be maintained episomally. Incorporating this heterogeneous viral replication machinery into a lentiviral vector leaves approximately 5 kb of additional cargo space available to accommodate therapeutic genes of interest.

Additionally, other control elements can be incorporated into the disclosed VIV system. As a non-limiting example, the expression of El or E2 or EBNA-1 or HBV polymerase can be driven by an inducible promoter. Further, as a non-limiting example, El and/or E2 can be expressed using plasmids or non-integrating viral vectors. Numerous types of inducible promoters are known in the art, and for the purposes of this invention, inducible promoters can include but are not limited to promoters that respond to antibiotics (i.e. , tetracyclines, aminoglycosides, penicillins, cephalosporins, polymyxins, etc.) or other drugs, copper and other metals, alcohol, steroids, light, oxygen, heat, cold, or other physical or chemical stimulation. For example, a method of using the disclosed viral system includes employing a tetracycline-inducible gene expression that depends upon a constant supply of the drug for expression of the cargo genes. A compound used to induce the inducible promoter may be added once or repeatedly depending on the duration of episomal replication and timing of cargo delivery that is desired. DNA replication and maintenance of the episome depends variously on El, E2 and/or EBNA-1 induction, which in turn depends upon an inducer of gene expression (i.e. , tetracycline).

An exemplary VIV system is shown in Figure 1. The disclosed VIV comprises at least one gene or nucleotide sequence of interest (e.g. cargo as shown in Figure 1A). The genes or sequences incorporated into the VIV will depend upon the purpose of the VIV. Referring generally to Figure 1, a lentivirus is packaged with an integrase-defective system or transduction is performed in the presence of clinical drugs used to block integrase activity (e.g., Dolutegravir or Raltegravir). Failing to integrate, the linear double strand vector DNA will generally circularize (e.g. Figure IB) using host enzymatic machinery. Optionally, a drug inducible promoter can be activated to express El and/or E2 protein if desired, which will in turn drive DNA replication. Therapeutic cargo will be expressed from the integrated cassette(s). In various embodiments, the compound that induces the inducible promoter (also referred to herein as an "inducer") is withdrawn or terminated. Termination of the inducer will down regulate El and/or E2 synthesis. In further embodiments, El and/or E2 production is effectively terminated. In either event, this will lead to declining levels of episomal DNA and eventually elimination of the vector construct.

A further exemplary diagram of a VIV system is shown in Figure 2. An El initiator protein is present and the cargo is GFP under an EF1-HTLV promoter. While Figures 1 and 2 depict a VIV system containing El, Figure 4, as described herein, depicts a VIV system containing both El and E2 on a single viral vector. In a further embodiment, in order to express both El and E2 from the same mRNA, an internal ribosome entry site (IRES) is added to allow for re-initiation of protein translation. Initiator proteins such as El and E2 can also be expressed on separate plasmids or non-integrating lentiviral vectors.

A further exemplary diagram of a VIV system is shown in Figure 4. The genetic cargo is represented by a CMV/GFP cassette. The cargo gene sequences may be amplified by polymerase chain reaction (PCR). For example, synthetic oligonucleotide primers can be used, such as primers which are identical to the 5' end of the cargo gene and/or complementary to the 3' end of the cargo gene. The 5' primer can be extended from its 5' end with a recognition site for an endonuclease. The 3' primer can also be extended at its 3' end with the complement for an endonuclease recognition. The resulting amplified cargo gene sequences can be annealed into a suitable vector, such as a lentiviral vector. Non-limiting examples of the genetic cargo include CMV/VEGF, CMV/anti-epidermal growth factor receptor (EGFR), an anti-HER2 antibody, or a miRNA suppressing C-C chemokine receptor type 5 (CCR5).

Suitable expression of the cargo may be determined by an appropriate assay. For example, DNA copy numbers can be measured by quantitative PCR. Protein products translated from non-limiting examples such as Vector 1 or Vector 19 (as described herein) can be measured, for example, by analytical flow cytometry. An ELISA assay may be used to detect the presence of certain cargo, such as a secreted protein, such as VEGF. A Western blot technique may also be used to detect certain cargo such as an antibody, such as anti-EGFR. Further, monitoring a reduction in cell surface expression of a cargo protein, such as a chemokine receptor such as CCR5, can also be employed.

In respect of the cargo, and serving as a non-limiting example, the gene encoding platelet-derived growth factor (PDGF) can be incorporated as a gene along with shRNA, siRNA, miRNA, and/or other gene-silencing RNA of interest into a VIV used to promote wound healing. The disclosed VIV system is not limited to a particular type of gene or sequence that can be expressed.

The disclosed VIV can incorporate numerous therapeutic or prophylactic genes or sequences including, for example, sequences that encode antibodies directed to an antigen associated with an infectious disease or cancer (including antigens on replicating pathogens and antigens that are exogenous toxins and antigens on tumor cells), platelet derived growth factor, vascular endothelial growth factor, brain derived growth factor, nerve growth factor, human growth factor, human chorionic gonadotropin, cystic fibrosis transmembrane conductance regulator (CFTR), dystrophin or dystrophin-associated complex, phenylalanine hydroxylase, lipoprotein lipases, a- and/or β-thalassemias, factor VIII, bone morphogenetic proteins 1 -4, cyclooxygenase 2, vascular endothelial growth factor, chemokine receptor CCR5, chemokine receptor CXCR4, chemokine receptor CXCR5, antisense DNA or RNA against autoimmune antigens involved in colitis, inflammatory bowel disease or Crohn's disease, small interfering RNA that are involved in addiction including miRNA regulating neural attenuation to opiates or alcohol, tumor suppressor genes, genes regulating cell survival including pro- or anti-apoptosis genes and pro- or anti-autophagy genes, genes encoding radiation resistance factors, genes encoding light emitting proteins used for tracking tumor cell metastasis or other cell trafficking phenomena, or a variety of other therapeutically useful sequences that may be used to condition the body for maximum effect of radiation, surgical or chemotherapeutics or to protect tissues against radiation, surgical or chemotherapeutics, to modify the host or graft tissues to improve organ transplantation or to suppress hyprerreactivity especially in the airway.

Without limiting any of the foregoing, cargo can include diagnostic proteins such as GRP and mCherry, as well as cDNAs, micoRNAs, shRNAs, and antibodies. Further, cargo can include specific cargo such as VEGF and BMP, as described herein.

In further aspects, it is desirable to maintain the genes in episomal form in a VIV system as a "safety switch." For example, where a particular gene product is toxic, withdrawal of the inducer molecule will reduce or terminate DNA replication. Episome numbers will subsequently decline, and the gene and vector will eventually disappear. Unlike traditional regulated gene expression as the safety switch, the disclosed expression construct is degraded by endogenous nucleases and diluted by cell division until it has effectively disappeared, thereby preventing any short- or long-term breakthrough expression.

In accordance with a further aspect, maintaining a gene, gene product, shRNA, siRNA, miRNA, and/or other gene-silencing RNA of interest in episomal form also allows for regulating the copy number over a broad range and at much higher levels than is achieved by traditional lentivirus transduction.

The disclosed VIV system presents numerous benefits. For instance, episomal DNA is less susceptible to chromosomal modification, which can lead to gene silencing of traditional transduction vectors. Likewise, VIV episomal DNA vectors support active gene delivery at least over short- to medium-range time intervals of about 1 to about 4 months, and possibly longer. In other embodiments of the invention, episomal DNA vectors support active gene delivery over a period of about 1, about 2, about 3, about 4, about 5, about 6, about 7, about 8, about 9, about 10, about 11, or about 12 weeks or longer. In other embodiments, episomal DNA vectors support active gene delivery over a period of about 1 month, 2 months, 3 months, 4 months, 5 months, 6 months, 7 months, 8 months, 9 months, 10 months, 11 months, 12 months, or longer. Any combination of these time periods can also be used in the methods of the invention, e.g., 1 month and 1 week, or 3 months and 2 weeks.

While there are benefits specifically associated with the use of a lentiviral carrier for incorporation of the disclosed VIV system, the disclosed system is not limited to a single type of viral vector. Any DNA virus or virus that uses a DNA intermediate can be used as a carrier for incorporating the VIV system herein, including but not limited to lentivirus, adeno- associated virus (AAV), adenovirus, vaccinia, herpes virus, measles virus, hepadnavirus, parvovirus and murine viruses.

Without limiting any of the foregoing, in an aspect of the invention, a non-integrating viral delivery system is disclosed. The system includes a viral carrier, wherein the viral carrier contains a one or more of a defective integrase gene; a heterologous viral episomal origin of replication; a sequence encoding at least one initiator protein specific for the heterologous viral episomal origin of replication, wherein expression of the sequence encoding the at least one initiator protein specific for the heterologous viral episomal origin of DNA replication is inducible; and at least one gene, gene product, shRNA, siRNA, miRNA, or other RNA of interest. The viral carrier may be a lentivirus. The heterologous viral episomal origin of DNA replication may be from a papillomavirus. The heterologous viral episomal origin of DNA replication may be from a human papillomavirus or a bovine papillomavirus.

The heterologous viral episomal origin of DNA replication may be from a human papillomavirus type 16 (HPV16). The heterologous viral episomal origin of DNA replication may be from a long control region (LCR) of HPV16. The heterologous viral episomal origin of DNA replication may include SEQ ID NO: 1. Optionally, the heterologous viral episomal origin of DNA replication may include a 5' truncation of SEQ ID NO: 1. The heterologous viral episomal origin of DNA replication may include a 5' truncation of at least about 200 nucleotides, or at least about 300 nucleotides, or at least about 400 nucleotides, or at least about 500 nucleotides, or at least about 600 nucleotides, or at least about 700 nucleotides of SEQ ID NO: 1.

Table 1 - Summary of Disease Targets and Related Description

antigen receptors to direct cellular recognition.

Gene editing CRISP, zinc finger nuclease, TALEN and other guided DNA modification systems that are used for gene editing and are not suitable for permanent or long-term expression in cells.

Safety studies This broad category encompasses situations where the

program objective is to introduce highly durable gene therapy such as integrating lentivirus vector, but an intermediate step is needed to assess safety of a proposed DNA construct and/or to obtain objective clinical responses justifying the introduction of a longer-lasting version of the same DNA construct.

Passive immunity Transient expression of a protective antibody or antigen

receptor to protect against anticipated pathogen encounters, bridge existing immunotherapies, combine with chemotherapy or radiation therapy, and to direct immunity to cancer, infectious disease, or long-term pathology that might include neurodegenerative disease or activators of autoimmunity targets.

Transcription/Differentiation Cellular factors including protein, lipid, DNA and/or RNA Factors may be needed to alter the fate of individual cells including fetal or adult stem cells where long-term expression would be detrimental to fully differentiated function or create a risk for malignant disease.

Short term growth factors Protein, peptide, DNA or RNA molecules intended to

stimulate cellular activity for the purposes of inducing cell growth, tissue formation, blood vessel formation, muscle growth, nerve growth, skin growth and other objective clinical responses where long term factor expression is detrimental to cell or tissue function.

Placebo control, dose Creates a placebo control with the same DNA cargo but escalation extremely low expression to monitor the impact of vector

delivery on clinical trial outcomes.

Accordingly, based on the intended disease target, a vector system can be designed using Quadrant 1, Quadrant 2, Quadrant 3, or Quadrant 4 components (see: Figure 21). Selecting Quadrant 1 components provide for transient basal expression of genetic cargo using the described vector systems. In most cases, the DNA copies numbers will be roughly 20- times below the highest levels that can be achieved with this system. Careful selection of promoters driving expression of the DNA cargo will further increase the flexibility and tissue specificity of this system. Selecting Quadrant 2 provides for high episomal DNA copy numbers with potentially very high gene expression levels again depending on promoter selection. Further, the use of shorter LCR fragments increases the size of DNA inserts that can be incorporated as cargo. Selecting Quadrant 3 also provides for high episomal copy numbers but slightly less than can be obtained in Quadrant 2. The advantage of Quadrant 3 is very low basal levels of episomal DNA making the system highly controllable by the introduction or not, of E1/E2 proteins. Selecting Quadrant 4 ensures very low expression such as might be required for a placebo control or initial dose of a dose escalation clinical trial or dosing test to establish optimal levels for a desired indication.

Accordingly, the selection process can be correlated to the LCR fragments employed herein thus rendering the disclosed systems highly adaptable depending on the disease target and the intended biological response.

Further, and without limiting any of the foregoing, in another aspect, a method of expressing at least one gene, gene product, shRNA, siRNA, miRNA, or other RNA of interest in a cell is provided. The method includes contacting the cell with an effective amount of a non-integrating viral delivery system, wherein the system includes a viral carrier, wherein the viral carrier contains a defective integrase gene; a heterologous viral episomal origin of replication; a sequence encoding at least one initiator protein specific for the heterologous viral episomal origin of replication, wherein expression of the sequence encoding the at least one initiator protein specific for the heterologous viral episomal origin of DNA replication is inducible; and at least one gene, gene product, shRNA, siRNA, miRNA, or other RNA of interest.

In another aspect, a method of expressing at least one gene, gene product, shRNA, siRNA, miRNA, or other RNA of interest in a subject in need thereof is provided. The method includes administering to the subject in need thereof an effective amount of a non-integrating viral delivery system, wherein the system includes a viral carrier, wherein the viral carrier contains a defective integrase gene; a heterologous viral episomal origin of replication; a sequence encoding at least one initiator protein specific for the heterologous viral episomal origin of replication, wherein expression of the sequence encoding the at least one initiator protein specific for the heterologous viral episomal origin of DNA replication is inducible; and at least one gene, gene product, shRNA, siRNA, miRNA, or other RNA of interest.

In situations when the second amount is higher than the first amount, the level of expression of the at least one gene, gene product, shRNA, siRNA, miRNA, or other RNA of interest may be increased.

Infectious Disease Methods of treating or preventing infectious disease are provided. Prophylactic delivery of monoclonal antibodies to high risk individuals is presently practiced, such as individuals at high risk of contracting an infectious disease, due to health status or geographic location. The prophylactic delivery includes delivery protective antibodies against a lethal viral agent, such as to protect individuals moving through an endemic region (e.g., military and aid workers entering an Ebola-infected region). Vaccines are largely untested for diseases such as Ebola or Lassa Fever virus or Dengue fever or Chikungunya virus or Plasmodium spp. causing malaria, and chronic expression of prophylactic antibody genes through the use of integrating vectors carries unknown health risks. Thus, there is a significant medical need for effective antibody expression that must be high but transient.

The disclosed VIV system and methods of delivering high copy numbers of a gene, gene product, shRNA, siRNA, miRNA, and/or other gene-silencing RNA of interest for a limited period satisfy this medical need. A non-limiting example of a gene product that can be delivered for treating an infectious disease is an antibody specific for the infectious disease in question.

In one aspect, the invention is directed to methods of treating, preventing, or minimizing conditions, symptoms, or side effects associated with infectious disease. In certain embodiments, the infectious disease can be human immunodeficiency virus (HIV), human T cell leukemia virus, Ebola virus, Lassa fever virus, dengue fever, Zika virus, malaria, tuberculosis, rabies, vaccinia virus or other infectious diseases. In some embodiments, a VIV system can be administered prophylactically or following infection with an infectious disease.

In another aspect, a VIV system can be used to prevent an infectious disease. Subjects suspected of having an increased risk of contracting a particular infection disease can receive administrations of a prophylactically effective amount of a VIV encoding an antibody that specifically targets the infectious disease in question.

In certain embodiments, the infectious disease can be human immunodeficiency virus (HIV), human T cell leukemia virus, Ebola virus, Lassa fever virus, dengue fever, Zika virus, malaria, tuberculosis, rabies, vaccinia virus or other infectious diseases. In certain

embodiments, a VIV vector can be administered prophylactically or following infection with an infectious disease.

Wound Healing

In another embodiment, the invention is directed to methods of treating, preventing, or minimizing conditions, symptoms, or side effects associated with wound healing. The disclosed composition can be administered systemically or directly to a wound after an accident, injury, or surgery. In the case of surgery, a VIV system may be administered prophylactically in order to expedite healing. In the case of a wound from an accident, injury, or surgery, a VIV system may be administered sometime after the formation of the wound. For instance, the VIV system may be administered within about 1, about 2, about 3, about 4, about 5, about 10, about 12, about 24, about 36, about 48, about 60, about 72, about 84, about 96, about 108, about 120, or about 168 hours of the formation of a wound. Another application of the methods and compositions of the invention is transient delivery of VIV constructs capable of expressing platelet growth factor that would accelerate wound healing. A high dose of platelet-derived growth factor (PDGF), related growth factors, fragments thereof, and nucleotide mutants related thereto is required very quickly but transiently. The disclosed system and methods are ideal for this type of application.

Additional short-term applications include expression of brain-derived growth factor for intermittent treatment of alcohol abuse, nerve growth factor for spinal cord regeneration, and topical applications for skin conditions.

Bone Disease or Injury In one embodiment, the disclosed invention is directed to a method of enhancing bone healing, comprising identifying a subject with a bone injury and administering to the subject a therapeutically effective amount of a viral delivery system according to the invention. The viral delivery system comprises a viral carrier, a heterologous viral episomal origin of replication, a sequence encoding an initiator protein specific for the heterologous viral episomal origin of replication, and at least one gene, gene product, shRNA, siRNA, miRNA, and/or other gene- silencing RNA of interest, wherein the viral carrier has a defective integrase gene, and wherein expression of the sequence encoding the initiator protein specific for the heterologous viral episomal origin of DNA replication is under the control of an inducible promoter. The bone injury can be, for example, resulting from an accident, injury, or surgery and may be bone nonunion, or acute fracture or required spinal fusion. In some embodiments, the gene, gene product, shRNA, siRNA, miRNA, and/or other gene-silencing RNA of interest encodes bone morphogenetic proteins 1-4 or cyclooxygenase-2 or vascular endothelial growth factor, or fragments thereof. Further, in certain embodiments mutants of the foregoing are preferable and are within the scope of the invention for treating a bone injury or related disease.

In one embodiment, the disclosed invention is directed to a method of enhancing bone healing, comprising identifying a subject with a bone disease and administering to the subject a therapeutically effective amount of a viral delivery system according to the invention. The viral delivery system comprises a viral carrier, a heterologous viral episomal origin of replication, a sequence encoding an initiator protein specific for the heterologous viral episomal origin of replication, and at least one gene, gene product, shRNA, siRNA, miRNA, and/or other gene- silencing RNA of interest, wherein the viral carrier has a defective integrase gene, and wherein expression of the sequence encoding the initiator protein specific for the heterologous viral episomal origin of DNA replication is under the control of an inducible promoter. The bone disease can be, for example, resulting from an accident, injury, or surgery and may be bone nonunion, or acute fracture or required spinal fusion. Additionally, the bone disease may be from low bone density, low blood flow to the bone, aging, hereditary conditions, and the like. In some embodiments, the gene, gene product, shRNA, siRNA, miRNA, and/or other gene- silencing RNA of interest encodes bone morphogenetic proteins 1-4 or cyclooxygenase-2 or vascular endothelial growth factor.

Hereditary Genetic Disease

Prader-Willi syndrome DC 15

Sickle-cell disease P l ip

Tay-Sachs disease P 15

Turner syndrome C X

In another embodiment, the invention is directed to methods of treating, preventing, or minimizing conditions, symptoms, or side effects associated with a hereditary genetic disease. Several examples of such hereditary genetic diseases are disclosed in Table 2 herein, along with the causal type of mutation and chromosome involved using the nomenclature below:

P - Point mutation, or any insertion/deletion entirely inside one gene

D - Deletion of a gene or genes

C - Whole chromosome extra, missing, or both (see Chromosome abnormality) T - Trinucleotide repeat disorders: gene is extended in length

Current gene therapy includes efforts to edit genomic DNA through gene deletion, replacement, or re-sequencing. Various gene therapy systems known in the art, including Talen, CRISPR-Cas9, zinc finger endonuclease, TALEN, and others, rely on delivery of genetic material by lentivirus transduction. But, unlike the disclosed invention, these systems may have unexpected consequences if left active in cells for extended periods because active chromosome modification systems may alter unexpected sites, leading to new genetic diseases including cancer. Truly practical systems for modification of host DNA require transient, well-regulated expression through methods such as the method disclosed herein.

Thus, in one embodiment, the disclosed invention is directed to a method of treating a hereditary genetic disease, comprising identifying a subject with a hereditary genetic disease and administering to the subject a therapeutically effective amount of a viral delivery system according to the invention. The viral delivery system comprises a one or more of a viral carrier, a heterologous viral episomal origin of replication, a sequence encoding an initiator protein specific for the heterologous viral episomal origin of replication, and at least one gene, gene product, shRNA, siRNA, miRNA, and/or other gene-silencing RNA of interest, wherein the viral carrier has a defective integrase gene, and wherein expression of the sequence encoding the initiator protein specific for the heterologous viral episomal origin of DNA replication is under the control of an inducible promoter. The hereditary genetic disease can be, for example, the diseases listed in Table 2, and in some embodiments, the gene, gene product, shRNA, siRNA, miRNA, and/or other gene-silencing RNA of interest encodes non-mutated versions of the genes listed in Table 2. Without limiting the foregoing, the specific hereditary genetic disease can be CF and treatment can be pursued by expressing a non-mutated form of CFTR as detailed herein.

In another embodiment, a guide RNA target sequence is incorporated into the disclosed VIV system. Guide RNA are sequences used to target gene editing machinery to specific sites within the host genome that are mutated or otherwise require correction. Inclusion of guide RNA within the cargo of a VIV system allows for a modification of a section of a chromosome that requires correction, and the same modification will occur within VIV to accelerate degradation and/or dilution by the host. In certain embodiments of the invention, the disclosed viral delivery system comprises one or more of a viral carrier, a heterologous viral episomal origin of replication, a sequence encoding an initiator protein specific for the heterologous viral episomal origin of replication, at least one gene, shRNA, siRNA, miRNA, and/or other gene- silencing RNA of interest, and at least one guide RNA, wherein the viral carrier has a defective integrase gene, and wherein expression of the sequence encoding the initiator protein specific for the heterologous viral episomal origin of DNA replication is under the control of an inducible promoter.

Ex vivo modification of cells or tissues

In another aspect, the VIV system may be used to modify cells or tissues that are used for disease therapy. Cells may include, without limitation, primary cells such as lymphocytes, stem cells, epithelial cells, neural cells and others. For example, the VIV system may be used to modify lymphocytes that are redirected to specific disease including cancer, infectious disease or autoimmunity, and where long-term presence of genetically modified cells poses a health risk. For example, a VIV system may also be used to program pluripotent stem cells that require high levels of transcript factors for a defined interval and where the long-term presence of an integrated viral vector is undesirable. Suitable epithelial cells include those used for synthetic skin or other applications. These may require the expression of trophic or growth factors during the initial treatment that would be deleterious to function of the normal tissue after treatment and are best delivered by the VIV systems disclosed herein.

Doses and Dosage Forms The disclosed VIV systems allow for short, medium, or long-term expression of genes or sequences of interest and episomal maintenance of the disclosed vectors. Accordingly, dosing regimens may vary based upon the condition being treated and the method of administration.

In one embodiment, VIVs may be administered to a subject in need in varying doses. Specifically, a subject may be administered > 10 ⁶ infectious doses (where 1 dose is needed on average to transduce 1 target cell). More specifically, a subject may be administered > 10 ⁷ , > 10 ⁸ , > 10 ⁹ , or > 10 ¹⁰ infectious doses. Upper limits of VIV dosing will be determined for each disease indication and will depend on toxi city/safety profiles for each individual product or product lot.

Additionally, VIVs may be administered once or twice a day. Alternatively, VIVs may be administered to a subject in need once a week, once every other week, once every three weeks, once a month, every other month, every three months, every six months, every nine months, once a year, every eighteen months, every two years, every 36 months, or every three years or more.

In yet another embodiment, the solid dosage form can include one or more excipients such as calcium carbonate, starch, sucrose, lactose, microcrystalline cellulose or gelatin. In addition, the solid dosage form can include, in addition to the excipients, a lubricant such as talc or magnesium stearate. In some embodiments, the oral dosage form can be immediate release, or a modified release form. Modified release dosage forms include controlled or extended release, enteric release, and the like. The excipients used in the modified release dosage forms are commonly known to a person of ordinary skill in the art.

In a further embodiment, the pharmaceutical composition comprising a VIV can be formulated as a sublingual or buccal dosage form. Such dosage forms comprise sublingual tablets or solution compositions that are administered under the tongue and buccal tablets that are placed between the cheek and gum.

In other embodiments, the liquid dosage form can include, in addition to commonly used simple diluents such as water and liquid paraffin, various excipients such as humectants, sweeteners, aromatics or preservatives. In particular embodiments, the composition comprising VIV or a pharmaceutically acceptable salt thereof can be formulated to be suitable for administration to a pediatric patient.

In one embodiment, the pharmaceutical composition can be formulated in a dosage form for parenteral administration, such as sterile aqueous solutions, suspensions, emulsions, non- aqueous solutions or suppositories. In other embodiments, the non-aqueous solutions or suspensions can include propyleneglycol, polyethyleneglycol, vegetable oils such as olive oil or injectable esters such as ethyl oleate. As a base for suppositories, witepsol, macrogol, tween 61, cacao oil, laurin oil or glycerinated gelatin can be used.

The dosage of the pharmaceutical composition can vary depending on the patient's weight, age, gender, administration time and mode, excretion rate, and the severity of disease.

In this example, Figure 1A represents an exemplary linear VIV construct for treating

CF, a hereditary disease. Herein, at least one of the "cargo" portions depicted in Figure 1A encodes cystic fibrosis transmembrane conductance regulator (CFTR) (NM_000492). The long terminal repeat (LTR) portions of the exemplary VIV construct can be used to circularize the viral nucleic acid, as shown in Figure IB.

Subjects suspected of having or diagnosed as having (CF) can receive administrations of a therapeutically effective amount of a VIV encoding cystic fibrosis transmembrane conductance regulator (CFTR), alone or in combination with one or more additional agents for the treatment of CF. VIV encoding CFTR and/or additional agents are administered orally, intranasally, intrathecally, intraocularly, intradermally, transmucosally, iontophoretically, topically, systemically, intravenously, subcutaneously, intraperitoneally, or intramuscularly according to methods known in the art or as described herein. Subjects are then evaluated weekly for the presence and/or severity of signs and symptoms associated with CF, including, but not limited to, e.g., poor growth, persistent cough, thick sputum and mucus, wheezing, breathlessness, decreased ability to exercise, repeated lung infections, inflamed nasal passage, greasy stools, intestinal blockage, and poor weight gain. Treatments are maintained until such a time as one or more signs or symptoms of CF are ameliorated or eliminated.

It is rationally predicted that subjects suspected of having or diagnosed as having CF and receiving therapeutically effective amounts of a VIV encoding CFTR will display reduced severity or elimination of one or more symptoms associated with CF. It is further rationally predicted that administration of VIV encoding CFTR in combination with one or more additional agents will have synergistic effects.

These results will show that VIV encoding CFTR is useful in the treatment of CF. Example 6 - VIV Containing El to Express Cargo

A vector according to Figure 2 was produced containing green fluorescent protein gene (GFP) as the cargo. DNA containing the complete Locus Control Region and El protein from human papillomavirus type 16 (NCBI accession number U89348; SEQ ID NO: 19) was chemically synthesized. Individual segments and/or coding sequences were initially synthesized. These were amplified by polymerase chain reaction (PCR) using synthetic oligonucleotide primers identical to the 5' end of green fluorescent protein gene and complementary to the 3' end of green fluorescent protein. The 5' primer (SEQ ID NO: 20) was extended from its 5' end with the recognition site for BamHI or EcoRI endonucl eases. The 3' primer (SEQ ID NO: 21) was extended at its 3' end with the complement of BamHI, or EcoRI endonucl ease recognition sites. The resulting amplified green fluorescent protein gene sequences were then digested with BamHI and EcoRI restriction endonucleases.

A lentiviral vector was obtained from System Biosciences, Inc. The plasmid was cleaved with BamHI and EcoRI enzymes, and mixed with excess amplified green fluorescent protein gene sequences in a 1 :3 ratio of insert to vector.

Enzymatic activity was then stopped by heat inactivation at 70 degrees Celsius for 20 minutes. The above mixture was cooled to room temperature to allow annealing.

The annealing reactions were performed with bacteriophage T4 DNA ligase for 30 minutes at room temperature. 2.5 microliters of the resulting ligation mix were added to 25 microliters of STBL3 competent bacterial cells.

Transfection was then carried out by a brief (1 minute) heat-shock at 42 degrees

Celsius.

Bacterial cells were streaked onto agar plates containing ampicillin to obtain bacterial cultures. These cultures were expanded in Luria broth.

To check for insertion of amplified green fluorescent protein gene sequences into the lentivirus vector packaging plasmid, DNA was extracted from the above bacterial cultures and purified by standard methods. Purified DNA was digested with the same endonucleases used to make the construct. Fragment lengths were analyzed by agarose gel electrophoresis, and the amplified green fluorescent protein gene sequences were verified by DNA sequencing using specific primers obtained from Eurofins MWG Operon LLC.

Lentivirus vector stocks were produced as follows. At least two lentiviral packaging plasmids plus the cargo plasmid were co-transfected into HEK cells where viral genes and genomic RNA are expressed, assembled into integrase-deficient lentivirus particles, and released into the culture medium. Cell-free supernatants were produced and collected during the interval of 3-10 days after transfection. Lentivirus particles were purified by standard procedures including a combination of methods that could include centrifugation, transient flow filtration, size exclusion chromatography, size exclusion filtration or ion exchange chromatography. The concentration and biological activity (transducing units per ml) for each stock were determined.

Mammalian cells, including 293T cells, were used to test for lentivirus-derived episome formation, copy number and expression. The 293T cells were transduced with integrase deficient lentivirus particles at a multiplicity of infection ranging from 1 to 10 in the presence of polybrene. Unabsorbed virus was removed by washing cells 3 hours after application, and cells were cultured for 3 days. Cells were observed in a fluorescence microscope and cells expressing GFP were counted. Untransduced 293 T cells were used as a negative control. Data was reported as GFP-positive cells per 100 viable cells in culture. A minimum of 300 cells were counted per microscope field and 5-10 fields were counted for each replicate experiment. Four independent transduction experiments comprising one negative control and three replicate experiments were performed to determine the frequency of transduced cells. The data is depicted in Figure 3, and shows expression of GFP across three replicate experiments.

Example 7 - VIV Containing El and E2 to Express Cargo

Referring to Figure 4, Vector 19 can be constructed to contain both El (SEQ ID NO: 6) and E2 (SEQ ID NO: 7) initiator proteins. Here, the genetic cargo is a CMV/GFP expression cassette under the control of an inducible promoter.

293T cells can be transduced with Vector 19 at a multiplicity of infection ranging from between 1 and 20 transducing units per cell. 3 hours later, cells are washed with medium to remove unadsorbed virions and returned to culture. 12-24 hours after transduction, cells are treated with at least one dosage of a compound that can induce the inducible promoter. Upon addition of a compound that can induce the inducible promoter, El and E2 mRNA are transcribed from the episome and combine and assemble on the Locus Control Region Fragment 2 (LCR/F2) (SEQ ID NO: 3) to trigger DNA replication. Lentivirus-derived episomes decay starting approximately 24-36 hours after the cessation of promoter induction. Protein products from the cargo in Vector 19 are measured by analytical flow cytometry.

Example 8 - Introducing El and E2 for Expressing Cargo

To determine the effect of El and E2 in expressing cargo, 293T cells were transduced with a D64V integrase-deficient lentiviral vector (i.e., vector in Figure 5 A) expressing mCherry and the full length HPV16 (SEQ ID NO. 1) long control region (LCR) or 3' fragments, as described for Fragment 1 (SEQ ID NO: 2), Fragment 2 (SEQ ID NO: 3), Fragment 3 (SEQ ID NO: 4), and Fragment 4 (SEQ ID NO: 5) herein.

Notably, in reference to Figure 5 A, the full length LCR or the 3' fragments were utilized in the LCR region depicted in Figure 5 A. More specifically, depictions of the designed constructs are demonstrated as Vectors 9-13 in Figure 7 herein. Additional elements shown in Figure 7 refer to: the psi packaging element (SEQ ID NO: 22); the rev element (SEQ ID NO: 23); the cPPT (central polypurine tract) element (SEQ ID NO: 24); and the posttranscriptional regulatory element of woodchuck hepatitis virus (WPRE) (SEQ ID NO: 25).

After 24 hours, cells were transfected with plasmids containing HPV16 El (SEQ ID

NO: 6) and E2 (SEQ ID NO: 7) with Lipofectamine 2000. After 2 days, mCherry expression was analyzed by FACS. The results for these experiments are depicted in Figure 6A herein.

To contrast with the above experiments wherein El and E2 were introduced through plasmids, a second set of experiments were performed as described below. Briefly, 293T cells were transduced with a D64V integrase-deficient lentiviral vector expressing mCherry and the full length HPV16 long control region (LCR) (SEQ ID NO: 1) or a shorter Fragment 1 (SEQ ID NO: 2) based on the generalized vector shown in Figure 5 A herein. At the same time, cells were transduced with lentivirus expressing HPV16 El (SEQ ID NO: 6) and E2 (SEQ ID NO: 7). After 2 days, mCherry expression was analyzed by FACS, as shown in Figure 6B herein. As shown in Figure 6B herein, a greater percentage of mCherry cells was achieved when El and E2 were introduced with the D64V integrase-deficient lentiviral vector expressing mCherry and the full-length LCR (SEQ ID NO: 1) or the shorter fragment 1 (also referred to herein as Fragment 1, and also referred to herein as SEQ ID NO: 2).

The data detailed in this Example demonstrate that when El and E2 are expressed via lentiviral-mediated expression, there was stronger expression and thus more activation of HPV ori (LCR) full-length and fragments.

Secondly, the data from this Example demonstrates that there is a difference in HPV ori activation depending on the size of the LCR region. For example, with reference to Figure 6, there was a more significant change in the expression of mCherry when using full-length LCR (SEQ ID NO: 1) and Fragment 1 (SEQ ID NO: 2), as compared with Fragments 2 (SEQ ID NO: 3), 3 (SEQ ID NO: 4), and 4 (SEQ ID NO: 5).

Example 9 - Expression of VEGF As mentioned herein, VEGF can be selected to be a "cargo" region for treating, among other things, a bone injury. To further analyze the level of VEGF expression, 293T cells were transduced with a D64V integrase-deficient lentiviral vector containing a human cDNA for VEGF (SEQ ID NO: 26) and Fragment 1 (SEQ ID NO: 2) of the HPV16 long control region (LCR) (see: Figure 5B for generalized description of VEGF-containing vector). At the same time, cells were transduced with lentiviral vectors containing HPV16 El (SEQ ID NO: 6) and E2 (SEQ ID NO: 7). After 2 days, cell culture media was collected and analyzed with an ELISA kit for VEGF (Thermo Scientific). As shown in Figure 8, there was an increase in VEGF levels (3,594 pg/ml) with the VEGF expressing vector, which was further increased with El and E2 (11,856 pg/ml).

In a manner similar to the mCherry results from Example 8 above, the results demonstrate that there was a difference in HPV ori activation depending on the size of the LCR region. As shown in Figure 8, there was an approximate 3 -fold change in VEGF levels after adding E1/E2. Therefore, the full-length LCR (SEQ ID NO: 1) or Fragment 1 (SEQ ID NO: 2) expresses a gene of interest (i.e., VEGF) at a low level, but when E1/E2 was introduced, there was a strong induction of expression. In contrast, the other fragments tested expressed at a higher initial level and so there was a reduced difference upon introducing E1/E2.

The linear vectors detailed herein circularize intracellularly as shown, for example in Figure 10, which depicts a circularization of Vector 20 (as shown in Figure 9). For purposes of experiments detailed herein, Figure 10 details a primer set as arrows which are located on the 3' and 5' Long Terminal Repeats (LTRs). This primer set has been designed to amplify the episomal form of the lentiviral vector, and does not amplify the integrated form of the vector. Appropriate primers for detection of lentiviral episomes contain the following sequences:

3'LTR Fwd CTAATTCACTCCCAACGAAG (SEQ ID NO: 11); and

5'LTR Rev GCCGAGTCCTGCGTCGAGAG (SEQ ID NO: 12).

In the experiments detailed herein, integrase-deficient lentiviral vector copy number was regulated by a combination of utilizing Vector 20 in combination with Vector 21 or Vector 22 or Vector 23 or Vector 24. Alternately, integrase-deficient lentiviral vector copy number was regulated by a combination of utilizing Vector 20 in combination with Vector 25 or Vector 26. Example 11 - Development of LCR Fragments and Related Vectors

As discussed herein, the LCR portion of the vectors detailed herein can be and were modified through the use of fragments such as Fragment 1 (SEQ ID NO: 2), Fragment 2 (SEQ ID NO: 3), Fragment 3 (SEQ ID NO: 4); and Fragment 4 (SEQ ID NO: 5). The genomic organization of the LCR and the fragments described herein is depicted in Figure 11. Therein, the full-length LCR (top portion) contains a series of API, YY1, El, and E2 binding sites. As shown, for example, in Figure 11, Fragment 1 (SEQ ID NO: 2), Fragment 2 (SEQ ID NO: 3), Fragment 3 (SEQ ID NO: 4), and Fragment 4 (SEQ ID NO: 5) represent increasing LCRs with increasing 5' truncations which reduces a series of API, YY1, and E2 binding sites. Lentiviral vectors which make use of the LCR fragments are detailed herein (e.g., Figure 7 and related Examples herein).

Example 12 - Testing of Vectors Containing LCR Fragments and E1/E2 Variants

To test vectors containing the various LCR fragments detailed herein, 293T cells were transduced with D64V integrase-deficient lentiviral vectors containing either full length HPV16 long control region (LCR) or Fragment 1 (SEQ ID NO: 2), Fragment 2 (SEQ ID NO: 3), Fragment 3 (SEQ ID NO: 4), and Fragment 4 (SEQ ID NO: 5) as described herein (see, for e.g., Figure 7 and related Examples herein).

After 24 hours, cells were transfected with plasmids containing HPV16 El (SEQ ID NO: 6) and E2 (SEQ ID NO: 7) with Lipofectamine 2000. After 2 days, DNA was extracted for analysis by qPCR. Primers represented by SEQ ID NO: 11 and SEQ ID NO: 12, which are specific for the episomal form of the lentiviral vector were used to determine the episomal copy number. Notably, this primer set amplified only 1- and 2-LTR episomes. The data for this Example is depicted in Figure 16. Therein, the numbers associated with the LCR and fragments thereof reflect a fold-change increase for each of the conditions following the addition of El and E2.

In a separate set of related experiments, analysis was carried out for mCherry expression from integrase-deficient lentiviral vectors containing the HPV LCR and 3' fragments thereof. Briefly, 293T cells were transduced with D64V integrase-deficient lentiviral vectors expressing mCherry and either full length HPV 16 long control region (LCR) or Fragment 1 (SEQ ID NO: 2), Fragment 2 (SEQ ID NO: 3), Fragment 3 (SEQ ID NO: 4), and Fragment 4 (SEQ ID NO: 5). At the same time, cells were transduced with lentivirus expressing HPV 16 El (SEQ ID NO: 6) and E2 (SEQ ID NO: 7). After 2 days, mCherry expression was analyzed by FACS.

As shown in Figure 13 A, the percent of mCherry cells are identified for each of the tested conditions. The numbers associated with the LCR and fragments thereof reflect a fold- change increase for each of the conditions following the addition of El and E2. In a separate set of related experiments, 293T cells were transduced with a D64V integrase-deficient lentiviral vector expressing mCherry and the full-length HPV16 long control region identified previously as SEQ ID NO: 1. At the same time, cells were transduced with lentivirus expressing HPV16 E1-T2A-E2 (SEQ ID NO: 10) from a single vector (see: Vector 25 from Figure 9). After 2 days, mCherry expression was analyzed by FACS and the data is depicted in Figure 13B. As shown therein, transduction with HPV16 E1-T2A-E2 (SEQ ID NO: 10) resulted in a significant increase in positive mCherry cells.

In a separate set of related experiments, an analysis was conducted of mCherry expression using integrase-deficient lentiviral vectors containing HPV LCR following the addition of El, El-C, and E2-11. Briefly, 293T cells were transduced with a D64V integrase- deficient lentiviral vector expressing mCherry and HPV16 LCR (SEQ ID NO: 1) or Fragment 1 (SEQ ID NO: 2). At the same time, cells were transduced with HPV 16 El (i.e., Vector 21 in Figure 9; and SEQ ID NO: 6) or a El carboxy (C)-terminal fragment (i.e.., Vector 22 in Figure 9; and SEQ ID NO: 8) and HPV 16 E2 (i.e., Vector 23 in Figure 9; and SEQ ID NO: 7) or HPV11 E2 (i.e., Vector 24 in Figure 9; and SEQ ID NO: 9). After 2 days, mCherry expression was analyzed by FACS. As shown in Figure 14, the percent of mCherry cells are identified for each of the tested conditions. The numbers associated with the tested conditions reflect a fold- change increase for each of the conditions following the addition of El and E2.

Example 13 - Antibody Expression As mentioned herein, one of the features of the disclosed system is the usefulness of the disclosed system to express an antibody. In a series of representative experiments detailed herein, an anti-HER2 antibody was expressed using the lentiviral vector system. Briefly, 293T cells were infected with a D64 integrase-deficient lentiviral vector (i.e.., Vector 20) containing an antibody sequence against HER2 (SEQ ID NO: 13) and the HPV LCR (SEQ ID NO: 1) sequence.

At the same time, cells were infected with lentiviral vectors containing El (SEQ ID NO: 6) and E2 (SEQ ID NO: 7). After 3 days, cell culture media was collected. Antibody was purified from the media using Protein A/G agarose beads. An immunoblot was performed using a sheep anti-human antibody (Thermo Scientific). Antibody production was increased with the addition of El and E2 as shown in Figure 15A. Further, as shown in Figure 15B, anti- HER2 IgG concentration was determined using the Easy Titer IgG kit (Thermo Scientific).

Further, as shown in Figure 16 herein, additional antibodies can also be expressed using the systems disclosed herein. In Figure 16, an immunoblot demonstrating expression of an anti-EGFR antibody (SEQ ID NO: 14) is shown. Briefly, 293T cells were infected with a D64 integrase-deficient lentiviral vector containing an antibody sequence against EGFR (see: SEQ ID NO: 14 below) and the HPV fragment 2 (SEQ ID NO: 3).

After 24 hours, cells were infected with lentiviral vectors containing El (SEQ ID NO: 6) and E2 (SEQ ID NO: 7). After 3 days, cell lysate and cell culture media was collected. Antibody was purified from media using Protein A/G agarose beads and extracted from cells by cell lysis. An immunoblot was performed using a sheep anti-human antibody (Thermo Scientific) and an anti-actin (Sigma) antibody for a protein loading control for cell lysate. Antibody production was increased in both cell lysate and media with the addition of El and E2, as shown in Figure 16.

Example 14 - microRNA Expression and Knock-Down

As mentioned herein, one of the features of the disclosed system is the usefulness of the disclosed system to express a microRNA. As a non-limiting example, constructs were designed to express microRNA for CCR5 based on the SEQ ID NO: 15.

Briefly, HeLa cells expressing CCR5 were infected with a D64 integrase-deficient lentiviral vector (i.e.., Vector 20) containing a microRNA sequence against CCR5 (SEQ ID NO: 15) and the full-length HPV LCR (SEQ ID NO: 1) sequence. At the same time, cells were infected with lentiviral vectors containing El and E2. After 3 days, cells were collected and analyzed for CCR5 expression by FACS analysis with an anti-CCR5 APC-conjugated antibody. As shown in Figure 17, the percentage of CCR5 positive cells decreased from 92.6% to 70.9% with LV-LCR miR-CCR5 and to 44% with LV-LCR miR-CCR5 plus El and E2.

In related experiments, a D64 integrase-deficient lentiviral vector containing a microRNA sequence against CCR5 and the Fragment 2 (SEQ ID NO: 3) LCR sequence were utilized. As shown in Figure 18, there was a similar decrease in CCR5 expression following the addition of miR-CCR5 and even more so when El and E2 were added.

Referring in more detail to Figure 18, the upper panels show the distribution of cells, each represented by a single dot, based on the level of expression of mCherry. The lower panels show the corresponding change in CCR5 expression that is related to the level of DNA replication and production of a miRNA against CCR5. CCR5 is detected by a fluorescent monoclonal antibody used for staining the cell surface. Without any LV vector (left panels) there is no expression of mCherry (all cells are in Sector 1) and CCR5 expression is uniformly high at around 200 fluorescence intensity units. By adding LV-LCR (Fragment 2; SEQ ID NO: 3) containing miRCCR5 we find cells with basal expression of mCherry (55% of cells now found in the Sector 2) and some reduction in CCR5 expression leading to a new population with fluorescence intensity centered around 30 intensity units (dashed line on the lower, center panel). By adding both LV-LCR miRCCR5 and a non-integrating lentivirus vector expressing El and E2 replication proteins, we find 18.8% of cells with highest expression of mCherry (Sector 3) and find a new population (curve 3, gray and dashed line) with even lower CCR5 expression that is less than 20 fluorescence intensity units. These data demonstrate the capacity for a VIV containing LCR Fragment 2 (SEQ ID NO: 3) to express a basal level of miRCCR5 that is biologically active in reducing cell surface expression of the CCR5 protein. Further, the results show the impact of adding E1/E2 DNA replication proteins on vector copy number (related to the expression of mCherry) and increased miRCCR5 expression leading to further reduction in cell surface CCR5 expression.

Example 15 - EBV-based Initiator Protein

As mentioned herein, initiator proteins such as El (SEQ ID NO: 6) and E2 (SEQ ID NO: 7) are used to augment the effectiveness of the systems described herein. An altemate initiator protein that can be used in the current system is EBNA-1 (SEQ ID NO: 32). Accordingly in a series of experiments, 293T cells were transduced with a D64V integrase- deficient lentiviral vector (i.e., Vector 27) expressing GFP and the Epstein-Barr Virus (EBV) OriP sequence (SEQ ID NO: 31).

After 24 hours, cells were transfected with a plasmid containing EBV EBNA-1 (SEQ ID NO: 32) with Lipofectamine 2000. After 2 days, GFP expression was analyzed by FACS. As shown in representative data in Figure 19, EBV plus EBNA resulted in enhanced GFP expression. Accordingly, this data demonstrates that the initiator protein/ori interaction is not limited to E1/E2 interactions but can also include Epstein-Barr viral components.

Example 16 - LCR Fragment Combinations and Analysis Based on the data detailed herein, varied levels of expression, as determined by episome copies per cell, can be attributed to the various LCR fragments tested herein. As shown in Figure 20, and moving from right to left, data for full-length LCR (SEQ ID NO: 1), Fragment 1 (SEQ ID NO: 2), Fragment 2 (SEQ ID NO: 3), Fragment 3 (SEQ ID NO: 4) and Fragment 4 (SEQ ID NO: 5) are shown with and without E1/E2.

Referring to both Figures 11 and 20, increasing deletions from the 5' end of LCR remove key functional elements. As detailed herein, basal activity can be defined by the number of episomal DNA copies measured by quantitative PCR assay, when LCR or fragments of LCR are present within a lentivirus-derived episome vector, without added E1/E2 proteins. Inducible activity can be measured by transfecting expression plasmids containing El and E2, then introducing a lentivirus-derived episome vector before measuring episomal DNA copy number per cell in a quantitative PCR assay. Similar results were obtained when the E1/E2 protein expression construct was delivered as a non-integrating lentivirus vector. As detailed herein, basal activity has been determined to be highest for Fragments 2, 3 and 4 of the LCR. This indicates that basal activity is suppressed by the presence of a YY1 transcription factor binding site that is present in both LCR and Fragment 1 but not Fragments 2-4, as shown diagrammatically in Figure 11. Within Fragments 2-4, Fragment 2 had the highest basal expression and was the only fragment to include both API transcription factor binding sites. Thus, basal transcription is increased when the YY1 site is removed and both API sites are preserved. As detailed herein, inducible activity was determined to be highest for Fragments 1 and 3, lower for Fragments 2 and 4, and lowest for intact LCR. There is an unidentified element within LCR that is not present in Fragment 1 and it acts to suppress inducible DNA replication. When the YY1 and API sites are present (Fragment 1), episomal DNA levels are lower compared to removing YY1 and all API sites (Fragment 3). When the API sites are present without YY1 (Fragment 2) or when YY1, API and two of four E2 binding sites are removed (Fragment 4) inducible episomal DNA formation is intermediate and similar to LCR.

As summarized in Figure 20, the data detailed herein demonstrates definable differences in basal level expression and the ability for expression to be induced. Based on this summary data, at least four quadrants of activity can be defined as shown initially in Figure 20.

Moving to Figure 21, the four quadrants represent varying degrees of activity attributable to the LCR and their fragments. For example, as shown in Figure 21, Quadrant 1 reflects low activity but 3-4 times higher activity than Quadrant 4, and with a smaller LCR fragment. Quadrant 2 reflects high activity, again with a smaller LCR fragment. Quadrant 3 reflects higher activity but this time with a relatively longer LCR fragment. Finally, Quadrant 4 reflects very low activity with a relatively longer LCR fragment.

As detailed in Figure 21, each Quadrant can reasonably be associated with a particular preferred outcome. As a first example, when a preferred outcome is for use in gene editing, a LCR chosen from Quadrant 1 can be selected. As a second example, when a preferred outcome is cellular reprogramming, a LCR from Quadrant 2 can be selected. As a third example, when a preferred outcome is immune stimulation, a LCR from Quadrant 3 can be selected. As a fourth example, when a preferred outcome is a placebo effect, a LCR from Quadrant 4 can be selected. Importantly, and based on the preferred outcome, varied LCR fragments can be employed using the current system.
