Abstract
Description
Field of the Invention
[0001] The present invention relates to an oncolytic immunotherapeutic agent and use of the oncolytic immunotherapeutic agent in treating cancer. Background of the Invention
[0003] Viruses have the unique ability to enter cells with high efficiency. After entering the cell, the viral genes are expressed and the virus replicates. This usually leads to the death of infected cells and the release of antigenic components of the cell, because the cell ruptures when the cell dies. Therefore, virus-mediated cell death tends to lead to an immune response that is enhanced by host recognition of these cell components (including those components derived from host cells and those components encoded or incorporated by the virus itself) and due to so-called damage-associated molecular patterns (DAMPs) (which help activate immune responses).
[0004] Viruses also bind to various mediators of the innate immune response as part of the host response to recognition of viral infection (via, for example, Toll-like receptors and cGAS / STING signaling) and recognition of pathogen-associated molecular patterns (PAMPs), leading to activation of interferon responses and inflammation, which are also immunogenic signals to the host. These immune responses can have an immunogenic benefit to cancer patients, such that immune responses to tumor antigens provide systemic overall benefit, leading to treatment of tumors that are not infected with the virus (including micrometastatic disease), and providing vaccination against recurrence.
[0005] The combined direct ('oncolytic') effect of the virus and an immune response against tumour antigens (including non-self 'neoantigens', i.e. derived from specific mutated genes in an individual's tumour) is known as 'oncolytic immunotherapy'.
[0006] Viruses can also be used as delivery vehicles ('vectors') to express heterologous genes inserted into the viral genome in infected cells. These properties make viruses useful for various biotechnological and medical applications. For example, viruses expressing heterologous therapeutic genes can be used for gene therapy. In the context of oncolytic immunotherapy, the genes delivered may include genes encoding specific tumor antigens, genes intended to induce an immune response or increase the immunogenicity of released antigens after viral replication and cell death, genes intended to shape the resulting immune response, genes that increase the general immune activation state of the tumor, or genes that increase the direct oncolytic properties (i.e., cytotoxic effects) of the virus. Importantly, viruses have the ability to deliver encoded molecules that are intended to help directly or selectively initiate, enhance, or shape a systemic anti-tumor immune response to a tumor, which may have benefits such as: reduced toxicity or focusing beneficial effects on tumors (including those not infected by the virus) rather than focusing off-target effects on normal (i.e., non-cancerous) tissues compared to systemic administration of these same molecules or systemic administration of other molecules targeting the same pathway.
[0007] It has been demonstrated that many viruses, including, for example, herpes simplex virus (HSV), can be used for oncolytic treatment of cancer. The HSV used for oncolytic treatment of cancer must be disabled so that it is no longer pathogenic, but can still enter tumor cells and kill them. Many disabling mutations for HSV have been identified, including the destruction of genes encoding ICP34.5, ICP6 and / or thymidine kinase, which can not prevent the virus from replicating in culture or in tumor tissue in vivo, but it prevents significant replication in normal tissue. Among them, only HSV with destroyed ICP34.5 gene replicates in many tumor cell types in vitro, and selectively replicates in tumor tissue in mouse tumor models, but not in surrounding tissues. Clinical trials of HSV with ICP34.5 or ICP34.5 and ICP6 deletions have also shown safety and selective replication in human tumor tissue.
[0008] As mentioned above, oncolytic viruses including HSV can also be used to deliver therapeutic genes in cancer treatment. This type of virus with ICP34.5 deletion, which has additionally deleted ICP47 and encodes a heterologous gene for GM-CSF, has also been tested in clinical trials, including Phase 3 trials conducted in melanoma, in which safety and effectiveness in humans are shown. GM-CSF is a proinflammatory cytokine that has multiple functions, including stimulating monocytes to leave the circulation and migrate into tissues, where they proliferate and mature into macrophages and dendritic cells. GM-CSF is important for the proliferation and maturation of antigen-presenting cells, and its activity is required for activating anti-tumor immune responses. Experimental data show that tumor responses can be seen in injected tumors, and tumor responses to a lesser extent can be seen in non-injected tumors. The response is often highly persistent (several months-several years), and survival benefits seem to be achieved in responding patients. In addition to direct oncolytic effects, each of these also indicates that the immune system is involved in cancer treatment. However, this and other data of oncolytic viruses generally indicate that not all tumors respond to treatment, and not all patients can gain a survival advantage. Therefore, there is a clear need for improvements in the field of oncolytic therapy.
[0009] It has recently been shown that oncolytic immunotherapy can lead to additive or synergistic therapeutic effects together with immune co-inhibitory pathway blockade (i.e., inhibition or 'antagonism' of immune checkpoint pathways, also known as immune co-inhibitory pathways). Immune co-inhibitory pathway blockade aims to block host immunosuppressive mechanisms, which are usually used to prevent the occurrence of autoimmunity. However, in cancer patients, these mechanisms can also be used to inhibit the induction of any immune response induced against the tumor or block the potential beneficial effects of the immune response.
[0010] The systemic blocking of these pathways by agents targeting cytotoxic T lymphocyte-associated molecule-4 (CTLA-4), PD-1 or PD-L1 has shown efficacy in many tumor types including melanoma and lung cancer. However, as expected, based on the mechanism of action, off-target toxicity may occur due to the induction of autoimmunity. Even so, these agents are sufficient to allow for considerable clinical utility. Other immune co-suppression pathways and related targets in development for agents thereof (mainly antibodies) include LAG-3, TIM-3, VISTA, CSF1R, IDO, CEACAM1, CD47. Due to the mechanism of action, the optimal clinical activity of these agents (such as PD1, PDL1, LAG-3, TIM-3, VISTA, CSF1R, IDO, CD47, CEACAM1) may require systemic administration or be present in all tumors, i.e., including the interface of targeted immune effector cells and tumors or other immunosuppressive mechanisms in / tumors. In certain cases, agents that are more localized, such as in only some tumors or in some lymph nodes, may also be most effective, such as agents that target CTLA-4.
[0011] An alternative method to increase the anti-tumor immune response of cancer patients is to target (activate) immune co-stimulatory pathways, i.e., to suppress immune co-suppression pathways in contrast. These pathways send activation signals to T cells and other immune cells, which are usually caused by the interaction of related ligands on antigen presenting cells (APC) and related receptors on T cells and other immune cells. Depending on ligand / receptor, these signals may cause activation of T cells and / or APC and / or NK cells and / or B cells (including specific subtypes) to increase, differentiation and proliferation of T cells to increase and / or differentiation and proliferation of APC and / or NK cells and / or B cells (including specific subtypes), or immunosuppressive T cells such as regulatory T cells to suppress activity. Therefore, it is expected that the activation of these pathways will lead to enhanced anti-tumor immune response, but it is also expected that the systemic activation of these pathways (i.e., general activation of immune response rather than specific or selective anti-tumor immune response) will cause considerable off-target toxicity in non-tumor tissues, and the degree of such off-target toxicity depends on the specific immune co-stimulatory pathways targeted. However, agents that target immune co-stimulatory pathways (primarily agonistic antibodies or, less commonly, soluble ligands to said receptors) (including agents targeting GITR, 4-1-BB, OX40, CD40, or ICOS) and are intended for systemic use (i.e., intravenous delivery) are in clinical development or have been proposed for clinical development.
[0012] In order for many of these methods targeting immune co-inhibition or co-inhibitory pathways to succeed, a pre-existing immune response to the tumor is required, that is, so that the pre-existing immune response can be enhanced or the blockade of the anti-tumor immune response can be delivered. It is also necessary to have an inflamed tumor microenvironment (which indicates this sustained response). The pre-existing immune response to tumor neoantigens seems to be particularly important for the activity of immune co-inhibitory pathway blockade and related drugs. Only some patients may have a sustained immune response to tumor antigens (including neoantigens and / or an inflamed tumor microenvironment, both of which are necessary for the optimal activity of these drugs). Therefore, oncolytic agents that can induce immune responses to tumor antigens (including neoantigens) and / or can induce an inflamed tumor microenvironment are attractive for use in combination with immune co-inhibitory pathway blockade and immune enhancement drugs. This may explain the promising combined anti-tumor effects of oncolytic agents and immune co-inhibitory pathway blockade in mice and humans observed so far.
[0013] The above discussion suggests that there is still much room for improving oncolytics as well as cancer therapies that exploit oncolytics, antitumor immune responses, and drugs that target immune co-inhibitory or co-stimulatory pathways. SUMMARY OF THE INVENTION
[0015] The present invention provides an oncolytic virus expressing an inhibitor of CTLA-4. The virus may also contain other immunomodulators. In particular, the virus may contain GM-CSF and / or at least one molecule targeting an immune co-stimulatory pathway. CTLA-4 inhibitors are used to block the co-inhibition pathway, i.e., interfere with the interaction between CTLA-4 and B7. GM-CSF helps to induce an inflammatory tumor microenvironment and stimulate the proliferation and maturation of antigen presenting cells (including dendritic cells), which helps to induce anti-tumor immune responses. These immune responses can be amplified by activating one or more immune co-stimulatory pathways using one or more immune co-stimulatory pathway activation molecules also delivered by an oncolytic virus.
[0016] Oncolytic viruses replicate within tumors, causing tumor cell lysis and release of tumor antigens, combined with local inflammation and activation of innate immune responses, all of which are beneficial for the activation of antitumor immune responses and the activity of inhibitors of CTLA-4 / B7 interactions.
[0017] The molecules that inhibit CTLA-4 / B7 interactions are delivered directly to the immune response-inducing tumor (including where it is expected to flow to the draining lymph nodes), and the immune enhancement produced by the inhibitor is concentrated on the tumor, thereby focusing on the tumor antigen present therein, reducing systemic toxicity and blocking the activation of regulatory T cells (Treg), and the activation of the regulatory T cells (Treg) can inhibit T cell activation in other ways at the immune response-inducing site. The molecules targeting CTLA-4 and the molecules of the optionally targeted immune co-stimulatory pathways are delivered to the tumor using an oncolytic virus to focus the amplification of the immune effect on the anti-tumor immune response, and reduce the amplification of the immune response for non-tumor antigens. Therefore, the immune cells in tumors and tumor-draining lymph nodes are generally affected by the molecules expressed by viruses rather than the selectivity of immune cells. This leads to an increase in the effectiveness of immune cell stimulation, and can also lead to a reduction in off-target toxicity. It is also important to focus the combined systemic immune co-inhibitory pathway blocking and immune co-stimulatory pathway activation on the tumor (i.e., so that the amplified immune response of the co-inhibitory blocking released therefrom is an anti-tumor immune response rather than a response for non-tumor antigens).
[0018] The present invention utilizes the following fact: when delivered by oncolytic virus, the action site of CTLA-4 blocking and optionally costimulatory pathway activation and GM-CSF expression is in tumor and / or tumor draining lymph nodes, but the result of this activation (enlarged systemic anti-tumor immune response) is systemic. This usually targets tumors, not just tumors to which oncolytic viruses have delivered one or more immunomodulatory molecules. Therefore, the oncolytic virus of the present invention provides improved cancer treatment by producing an improved immune response focused on tumors. The oncolytic virus of the present invention also provides improved anti-tumor immunostimulatory effects, so that immune-mediated effects on tumors (including micrometastatic diseases) that are not destroyed by oncolysis are enhanced, resulting in more effective destruction of these tumors and more effective long-term anti-tumor vaccination, to prevent future recurrence and improve overall survival rate.
[0019] The anti-tumor efficacy is improved when the oncolytic viruses of the present invention are used as a single agent and when the viruses are used in combination with other anti-cancer modalities, including chemotherapy, treatment with targeted agents, irradiation, and in preferred embodiments, immune checkpoint blockade drugs (i.e., antagonists of immune co-inhibitory pathways, such as antibodies to PD1 or PD-L1) and / or agonists of immune co-stimulatory pathways.
[0020] Therefore, the present invention provides an oncolytic virus encoding a CTLA-4 inhibitor. The CTLA-4 inhibitor is preferably an anti-CTLA-4 antibody or antibody-like molecule, or an antigen-binding fragment thereof.
[0021] The virus may further comprise: (i) a GM-CSF encoding gene; and / or (ii) an immune co-stimulatory pathway activating molecule or an immune co-stimulatory pathway activating molecule encoding gene. The virus may encode more than one immune co-stimulatory pathway activating molecule / gene.
[0022] The immune co-stimulatory pathway activating molecule is preferably GITRL, 4-1-BBL, OX40L, ICOSL or CD40L or any modified form thereof. Examples of modified forms include agonists of co-stimulatory pathways that are secreted rather than membrane-bound, and / or agonists that are modified to form multimers of the protein.
[0023] The virus can be a modified clinical isolate, such as a modified clinical isolate of a virus, wherein the clinical isolate kills two or more tumor cell lines in vitro more rapidly and / or at a lower dose than one or more reference clinical isolates of the same virus.
[0024] The virus is preferably a herpes simplex virus (HSV), such as HSV 1. HSV generally does not express a functional ICP34.5 and / or a functional ICP47 and / or expresses the US11 gene as an immediate early gene.

[0033] Fig. 1 depicts the structure of the virus for constructing an exemplary virus of the present invention, which comprises an anti-mouse or anti-human CTLA-4 construct, which is a codon-optimized secreted scFv molecule connected to a human or mouse IgG1 Fc region. The scFv contains variable light and heavy chains from 9D9 (initial mouse antibody for verifying CTLA-4; WO2007 / 123737: mouse form) or from ipilimumab (WO2014 / 066532; human form) connected by 15-mer [G4S] 3 (GGGGSGGGGSGGGGS). The virus is a modified form of strain HSV1RH018A (clinical strain 18). ICP34.5 and ICP47 genes are inactivated in the virus. The US11 gene is placed under the control of the ICP47 immediate early gene promoter by deleting the ICP47 promoter. The expression cassette is inserted into the ICP34.5 locus. In virus 17, the expression cassette contains the human GM-CSF gene under the control of the CMV promoter and the GALV gene under the control of the RSV promoter. Virus 16 is identical to virus 17 except that it contains human GM-CSF instead of mouse GM-CSF. Viruses 25 and 29 are identical to viruses 16 and 17, respectively, except that they each additionally contain a GFP gene under the control of the MMLV promoter in the expression cassette. Viruses 27 and 31 are identical to viruses 25 and 29, respectively, except that the GFP gene is replaced by mouse anti-CTLA4 and human anti-CTLA4, respectively.
[0034] FIG. 2 depicts the structure of plasmids used to construct exemplary viruses of the present invention.
[0035] Figure 3The structures of anti-mouse or human CTLA-4 constructs are shown, which are codon-optimized secreted scFv molecules linked to human or mouse IgG1 Fc regions. The scFv contains linked ([G4S]3) variable light and variable heavy chains from 9D9 (the initial mouse antibody originally used to validate CTLA-4; US2011044953: mouse form) or from ipilimumab (US20150283234; human form). The resulting structures of CTLA-4 inhibitors are also shown.
[0036] Figure 4 is a Western blot demonstrating that anti-mouse CTLA-4 is expressed by virus 27. The gel used is a reduced denatured PVDF membrane tris-glycine gel. Anti-CTLA-4 was detected using an alkaline phosphatase labeled anti-mouse IgG1 antibody. Lane 1: spectra broad range ladder; Lane 2: neat supernatant of virus 27; Lane 3: virus 27 supernatant diluted 1:2; Lane 4: virus 27 supernatant diluted 1:4; Lane 5: virus 27 supernatant diluted 1:8; Lane 6: virus 27 supernatant diluted 1:16; Lane 7: virus 27 supernatant diluted 1:32; Lane 8: negative control virus (neat supernatant). The expected size of anti-CTLA-4 (reduced) is 57 kDa.
[0037] Figure 5 The superior tumor control and shrinkage of uninjected tumors by a virus expressing anti-mCTLA-4 (virus 27) was shown compared to an otherwise identical virus not expressing CTLA-4 (virus 16). The virus dose used was 5x10 4 pfu (50ul of 1x10 6 pfu / ml), given three times in one week. For virus 16 uninjected tumors, this dose level of virus was subtherapeutic, allowing the benefit of delivery of additional molecules encoded by virus 27 to be clearly seen.
[0038] Figure 6 The superior tumor control and shrinkage in both injected and uninjected tumors of the virus expressing anti-mCTLA-4 (virus 27) compared to an otherwise identical virus not expressing CTLA-4 (virus 16) is shown. The dose of virus used in the right tumor of the virus expressing anti-mCTLA-4 (virus 27) was 5x10 4 pfu. Each line represents a different mouse.
[0039] Figure 7Shown are the effects of combined treatment of bilateral mouse A20 tumors using anti-PD1 and virus 27 expressing mGM-CSF, GALVR, and anti-mCTLA-4. The top panel shows the effect of anti-PD1 alone on injected (right) and uninjected (left) tumors. The middle panel shows the effect of virus 27 alone on injected (right) and uninjected (left) tumors. The bottom panel shows the excellent tumor control and shrinkage achieved when both anti-PD1 and virus 27 were injected into the right tumor. Improved anti-tumor effects of the combined treatment were observed in both injected (right) and uninjected (left) tumors. Each line represents a different mouse.
[0040] Figure 8 Shown in knock-in mice expressing human CTLA-4 in mouse MC38 tumors, superior tumor control and shrinkage effects of virus 31 expressing hGM-CSF, GALVR and anti-human CTLA-4 compared to virus 17 expressing only hGM-CSF and GALVR. The anti-tumor effect of virus 31 was observed when the virus was administered alone or in combination with anti-PD1. Superior tumor control and shrinkage of injected tumors were obtained using virus 31 expressing anti-human CTLA-4 compared to viruses that did not express anti-human CTLA-4 but were otherwise identical (left figure). This effect was further enhanced when treatment with the virus was combined with anti-PD1 treatment. Excellent tumor control and shrinkage were also observed in non-injected tumors (right figure) when treatment with either virus was combined with anti-PD1 treatment. This improvement was more pronounced for virus 31 expressing anti-CTLA-4 compared to virus 17 that did not express anti-CTLA-4. Each line represents a different mouse.

[0089] Oncolytic viruses
[0090] The virus of the present invention is oncolytic. Oncolytic viruses are viruses that infect tumor cells and replicate in tumor cells, thereby killing tumor cells. Therefore, the virus of the present invention has the ability to replicate. Preferably, the virus has the ability to selectively replicate in tumors. If the virus replicates more efficiently in tumor tissue than in non-tumor tissue, the virus has the ability to selectively replicate in tumor tissue. The ability of a virus to replicate in different tissue types can be determined using standard techniques in the art.
[0091] The virus of the present invention can be any virus with these characteristics, including herpes virus, pox virus, adenovirus, retrovirus, rhabdovirus, paramyxovirus or reovirus, or any species or strain in these larger groups. The virus of the present invention can be wild type (i.e. unchanged compared to the parent virus species), or have gene disruption or gene addition. As for which of these situations it belongs to, it will depend on the virus species to be used. Preferably, the virus is a species of herpes virus, more preferably a strain of HSV, including strains of HSV1 and HSV2, and most preferably a strain of HSV1. In a particularly preferred embodiment, the virus of the present invention is based on a clinical isolate of the virus species to be used. Clinical isolates can be selected based on its particularly advantageous properties for treating cancer.
[0092] The virus can be a modified clinical isolate, wherein the clinical isolate kills two or more tumor cell lines in vitro more quickly and / or with a lower dosage than one or more reference clinical isolates of the same virus species. Typically, the clinical isolate will kill two or more tumor cell lines within 48 hours, preferably within 24 hours, of an infection with a multiplicity of infection (MOI) less than or equal to 0.1. Preferably, the clinical isolate will kill a wide range of tumor cell lines, such as 2, 3, 4, 5, 6, 7, 8, 9, 10 tumor cell lines or, for example, all cell lines in the following human tumor cell lines: U87MG (glioma), HT29 (colorectal cancer), LNCaP (prostate cancer), MDA-MB-231 (breast cancer), SK-MEL-28 (melanoma), Fadu (squamous cell carcinoma), MCF7 (breast cancer), A549 (lung cancer), MIAPACA-2 (pancreatic cancer), CAPAN-1 (pancreatic cancer), HT1080 (fibrosarcoma).

[0106] strain RH040B, accession number ECCAC 16121908; and
[0107] strain RH015A, accession number ECCAC 16121903.
[0108] Most preferably, the virus of the invention is strain RH018A with accession number EACC 16121904. Any of the deposited virus strains may be modified as defined herein.
[0109] The HSV of the present invention is capable of selectively replicating in tumors (such as human tumors). Typically, HSV replicates efficiently in target tumors, but not in non-tumor tissues. The HSV may contain one or more mutations in one or more viral genes that inhibit replication in normal tissues but still allow replication in tumors. For example, the mutation may be a mutation that prevents HSV from expressing functional ICP34.5, ICP6 and / or thymidine kinase.
[0110] In a preferred embodiment, the ICP34.5 encoding gene is mutated to confer selective oncolytic activity to HSV. Mutations of the ICP34.5 encoding gene that prevent functional ICP34.5 expression are described in Chou et al. (1990) Science 250:1262-1266, Maclean et al. (1991) J. Gen. Virol. 72:631-639 and Liu et al. (2003) Gene Therapy 10:292-303 (which are incorporated herein by reference). The ICP6 encoding gene and / or the thymidine kinase encoding gene may also be inactivated, as may other genes, as long as such inactivation does not prevent the virus from infecting the tumor or replicating therein.
[0111] HSV may contain additional mutations that enhance HSV replication in tumors. The resulting enhanced replication of the virus in tumors not only leads to enhanced direct "oncolytic" killing of tumor cells by the virus, but also increases the level of heterologous (i.e., genes inserted into the virus, in the case of the virus of the present invention, genes encoding CTLA-4 inhibitors, GM-CSF and / or immune co-stimulatory pathway activating molecules) gene expression and increases the amount of tumor antigens released when tumor cells die, both of which can also improve the immunogenic properties of the therapy for cancer treatment. For example, in a preferred embodiment of the present invention, the deletion of the ICP47 encoding gene in a manner that places the US11 gene under the control of the immediate early promoter that normally controls the expression of the ICP47 encoding gene leads to enhanced replication in tumors (see Liu et al., 2003, which is incorporated herein by reference).
[0112] Other mutations that place the US11 coding sequence (which is a HSV late gene) under the control of a promoter that is independent of viral replication can also be introduced into the virus of the present invention. Such mutations allow US11 to be expressed before HSV replication occurs and enhance viral replication in tumors. In particular, such mutations enhance the replication of HSV lacking a functional ICP34.5 coding gene.
[0113] Therefore, in one embodiment, the HSV of the present invention comprises a US11 gene operably linked to a promoter, wherein the activity of the promoter is independent of viral replication. The promoter may be an immediate early (IE) promoter or a non-HSV promoter active in mammalian (preferably human) tumor cells. The promoter may be, for example, a eukaryotic promoter, such as a promoter derived from a mammalian (preferably human) genome. The promoter may be a ubiquitous promoter (such as a promoter of β-actin or tubulin) or a cell-specific promoter, such as a tumor-specific promoter. The promoter may be a viral promoter, such as a Moloney murine leukemia virus long terminal repeat (MMLV LTR) promoter or a human or mouse cytomegalovirus (CMV) IE promoter. The HSV immediate early (IE) promoter is well known in the art. The HSV IE promoter may be a promoter that drives the expression of ICP0, ICP4, ICP22, ICP27 or ICP47.
[0114] The above genes (whose functional inactivation provides the virus with the property of tumor selectivity) can be functionally inactivated by any suitable method, for example, by deleting or replacing all or part of the gene and / or the control sequence of the gene, or by inserting or replacing one or more nucleic acids into or replacing the gene and / or the control sequence of the gene. For example, homologous recombination methods standard in the art can be used to produce the virus of the present invention. Alternatively, a method based on bacterial artificial chromosomes (BAC) can be used.
[0115] As used herein, the term "gene" is intended to mean a nucleotide sequence encoding a protein, i.e., the coding sequence of a gene. By mutating the gene itself or the control sequences flanking the gene, such as a promoter sequence, the various genes mentioned above can be rendered inoperative. Deletion can remove one or more parts of a gene, the entire gene, or the entire gene and all or some control sequences. For example, only one nucleotide in a gene can be deleted, resulting in a frameshift. However, larger deletions can be performed, such as at least about 25%, more preferably at least about 50% of the total coding sequence and / or non-coding sequence. In a preferred embodiment, deletion is performed on a gene to be functionally inactivated. For example, the entire gene and optionally some flanking sequences can be removed from a virus. When two or more gene copies are present in the viral genome, both copies of the gene are rendered functionally inactive.
[0116] Gene inactivation can be achieved by replacing other sequences, for example, by replacing all or part of an endogenous gene with a heterologous gene and optionally a promoter sequence. In the absence of a promoter sequence being replaced, a heterologous gene can be inserted so that it is controlled by the promoter of the gene to be functionally inactivated. In the HSV of the present invention, the ICP34.5 encoding gene is preferably inactivated by inserting one or more heterologous genes and one or more promoter sequences operably linked thereto or optionally other regulatory elements (such as a polyadenylation sequence) into the locus of each ICP34.5 encoding gene.
[0117] The virus of the present invention is used to express CTLA-4 inhibitors and optionally GM-CSF and / or immune co-stimulatory pathway activating molecules in tumors. This is usually achieved by inserting heterologous genes encoding CTLA-4 inhibitors and optionally heterologous genes encoding GM-CSF and / or heterologous genes encoding immune co-stimulatory pathway activating molecules into the genome of a virus with selective replication ability, wherein each gene is under the control of a promoter sequence. Since the replication of this virus will occur selectively in tumor tissue, the expression of the virus to CTLA-4 inhibitors and, if present, GM-CSF and / or immune co-stimulatory activating proteins is enhanced in tumor tissue compared to non-tumor tissues in vivo. In the case of higher expression in tumors compared to other tissues of the body, enhanced expression occurs. Proteins expressed by oncolytic viruses are also expected to be present in tumor-draining lymph nodes infected by oncolytic viruses, including due to the transport of expressed proteins and viruses from tumors to antigen presenting cells or thereon. Thus, the present invention provides the benefit of selective expression of a CTLA-4 inhibitor and any co-expressed GM-CSF and / or immune co-stimulatory pathway activating molecules in tumors and tumor draining lymph nodes in combination with the anti-tumor effects provided by oncolytic virus replication.
[0118] The virus of the present invention comprises a CTLA-4 inhibitor. A CTLA-4 inhibitor is a molecule that is usually a peptide or protein that binds to CTLA-4 and reduces or blocks signal transduction through CTLA-4. By reducing CTLA-4 signal transduction, the inhibitor reduces or removes the blockade of CTLA-4 on the immune stimulation pathway.
[0119] The CTLA-4 inhibitor is preferably an antibody or an antigen-binding fragment thereof.
[0120] The term "antibody" mentioned herein includes complete antibodies and any antigen-binding fragments thereof (i.e., "antigen-binding portions") or single chains. An antibody refers to a glycoprotein comprising at least two heavy (H) chains and two light (κ) (L) chains interconnected by disulfide bonds, or an antigen-binding portion thereof. Each heavy chain consists of a heavy chain variable region (abbreviated herein as VH) and a heavy chain constant region. Each light chain consists of a light chain variable region (abbreviated herein as VL) and a light chain constant region. The variable regions of the heavy and light chains contain binding domains that interact with antigens. The VH and VL regions can be further subdivided into hypervariable regions, called complementarity determining regions (CDRs), interspersed with more conserved regions, called framework regions (FRs). The constant region of an antibody can mediate the binding of immunoglobulins to host tissues or factors, including various cells of the immune system (e.g., effector cells) and the first component (Clq) of the classical complement system.
[0121] The antibody is usually a monoclonal antibody. The antibody may be a chimeric antibody. The antibody is preferably a humanized antibody, more preferably a human antibody.
[0122] The term "antigen-binding fragment" of an antibody refers to one or more fragments of an antibody that retains the ability to specifically bind to CTLA-4. The antigen-binding fragment also retains the ability to inhibit CTLA-4, thereby reducing or eliminating the CTLA-4 blockade of the stimulatory immune response. Examples of suitable fragments include Fab fragments, F(ab')2 fragments, Fab' fragments, Fd fragments, Fv fragments, dAb fragments, and isolated complementary determining regions (CDRs). Single-chain antibodies such as scFv and heavy chain antibodies such as VHH and camel antibodies are also intended to be included in the term "antigen-binding portion" of an antibody. In a preferred embodiment, the antibody is a scFv. Examples of suitable scFv molecules are disclosed, for example, in WO2007 / 123737 and WO2014 / 066532 (which are incorporated herein by reference).
[0123] The antibody coding sequence generally encodes an antibody or antibody fragment having an N-terminal signal sequence. The signal sequence may have the amino acid sequence shown in SEQ ID NO: 7. For example, the signal sequence is contained in a scFv having an amino acid sequence shown in SEQ ID NO: 9 and encoded by the nucleotide sequence shown in SEQ ID NO: 10, and an scFv having an amino acid sequence shown in SEQ ID NO: 14 and encoded by the nucleotide sequence shown in SEQ ID NO: 15.
[0124] In an antibody or antibody fragment, the light chain and heavy chain sequences can be connected by an amino acid linker. The linker generally comprises about 15 to about 25 amino acids, such as about 18 or 20 amino acids. Any suitable linker can be used, such as a linker comprising glycine and serine residues (e.g., the amino acid sequence shown in SEQ ID NO:8). For example, the linker is included in an scFv with an amino acid sequence shown in SEQ ID NO:9 and encoded by the nucleotide sequence shown in SEQ ID NO:10, and an scFv with an amino acid sequence shown in SEQ ID NO:14 and encoded by the nucleotide sequence shown in SEQ ID NO:15. Both are preferred antibody fragments for use in the present invention.
[0125] Other antibody fragments with similar structures are also preferred. Therefore, the virus of the present invention can encode an antibody or fragment comprising or essentially consisting of a light chain variable region, a linker, a heavy chain variable region, a heavy chain CH1 domain, a heavy chain CH2 domain, and a heavy chain CH3 domain. The virus can also encode a signal sequence at the N-terminal end of the antibody.
[0126] The antibody or antibody fragment of the present invention may preferably comprise an Fc region, which is an IgG1, IgG2, IgG3 or IgG4 region, more preferably an IgG1 region. Preferably, the antibody is a scFv antibody in which the scFv is linked to the IgG heavy chain CH2 and CH3 domains.
[0127] Preferred CTLA-4 antibodies or fragments include the heavy chain variable region shown in SEQ ID NO:3 and / or the light chain variable region shown in SEQ ID NO:1 or the heavy chain variable region shown in SEQ ID NO:11 and / or the light chain variable region shown in SEQ ID NO:12. The antibody may include a heavy chain CH1 domain having the amino acid sequence shown in SEQ ID NO:4 and / or a CH2 / CH3 domain shown in SEQ ID NO:5. The antibody may include the light chain amino acid sequence shown in SEQ ID NO:2. The antibodies of the present invention may optionally include a variant of one of these heavy or light chain variable regions or CDR sequences. For example, the variant may be a substitution, deletion or addition variant of any of the above amino acid sequences.
[0128] Variant antibodies may comprise 1, 2, 3, 4, 5, up to 10, up to 20, up to 30 or more amino acid substitutions and / or deletions from the specific sequences and fragments discussed above, while maintaining the activity of the antibodies described herein. "Deletion" variants may comprise, for example, 1, 2, 3, 4 or 5 single amino acids or one or more small groups of amino acids (such as 2, 3, 4 or 5 amino acids). "Replacement" variants preferably include replacing one or more amino acids with the same number of amino acids and producing conservative amino acid substitutions. For example, amino acids may be replaced by alternative amino acids (e.g., another basic amino acid, another acidic amino acid, another neutral amino acid, another charged amino acid, another hydrophilic amino acid, another hydrophobic amino acid, another polar amino acid, another aromatic amino acid, or another aliphatic amino acid) having similar properties.
[0129] The virus of the present invention comprises one or more polynucleotide sequences encoding a CTLA-4 inhibitor. The polynucleotide sequence is under the control of a suitable promoter. The virus may comprise a first polynucleotide sequence encoding an antibody heavy chain variable region and a second polynucleotide encoding an antibody light chain variable region. The first polynucleotide may encode a full-length heavy chain and / or the second polynucleotide may encode a full-length light chain. The first and second polynucleotides may be under the control of a single promoter, optionally with an IRES, or may be under the control of two separate promoters. The separate promoters may be the same or different.
[0130] The first polynucleotide may comprise, consist essentially of, or consist of the heavy chain variable region encoding sequence shown in SEQ ID NO: 9, and / or the second polynucleotide may comprise, consist essentially of, or consist of the heavy chain variable region encoding sequence shown in SEQ ID NO: 10. The first polynucleotide may comprise, consist essentially of, or consist of the heavy chain variable region encoding sequence shown in SEQ ID NO: 19, and / or the second polynucleotide may comprise, consist essentially of, or consist of the heavy chain variable region encoding sequence shown in SEQ ID NO: 20.
[0131] The first and / or second polynucleotide sequence may be a variant of SEQ ID NO: 9, 10, 19 or 20. For example, the variant may be a substitution, deletion or addition variant of any of these nucleic acid sequences. The variant polynucleotide may comprise 1, 2, 3, 4, 5, up to 10, up to 20, up to 30, up to 40, up to 50, up to 75 or more nucleic acid substitutions and / or deletions from SEQ ID NO: 9, 10, 19 or 20.
[0132] Suitable variants can have at least 70% homology with any of the polynucleotides of the nucleic acid sequences disclosed herein, preferably at least 80% or 90%, more preferably at least 95%, 97% or 99% homology therewith. Preferably, at least for the coding region of the polynucleotide, there are homology and identity at these levels. The method of measuring homology is well known in the art, and it will be appreciated by those skilled in the art that in this specification, homology is calculated based on nucleic acid identity. This homology can be present in at least 15, preferably at least 30, for example at least 40, 60, 100, 200 or more continuous nucleotides. This homology can be present in the entire length of the unmodified polynucleotide sequence.
[0133] Methods for measuring polynucleotide homology or identity are known in the art. For example, the UWGCG package provides the BESTFIT program, which can be used to calculate homology (e.g., used under its default settings) (Devereux et al. (1984) Nucleic Acids Research 12, pp. 387-395).
[0134] The PILEUP and BLAST algorithms can also be used to calculate homology or align sequences (usually under their default settings), for example as described in Altschul SF (1993) J Mol Evol 36:290-300; Altschul, S, F et al. (1990) J Mol Biol 215:403-10.
[0135] Software for performing BLAST analysis can be publicly available through the National Center for Biotechnology Information (http: / / www.ncbi.nlm.nih.gov / ). The algorithm involves first identifying high scoring sequence pairs (HSPs) by identifying short words of length W in the query sequence that match or satisfy a certain positive threshold score T when aligned with a word of the same length in the database sequence. T is called the neighborhood wordscore threshold (Altschul et al., supra). These initial neighborhood word hits are used as seeds to initiate searches to find HSPs containing them. As long as the cumulative alignment score can be increased, the word hits are extended in both directions along each sequence. The extension of the word hits in each direction is stopped when: the cumulative alignment score becomes zero or lower due to the accumulation of one or more negative scoring residue alignments; or the end of either sequence is reached. The BLAST algorithm parameters W, T and X determine the sensitivity and speed of the alignment. The BLAST program uses as defaults a wordlength (W) of 11, the BLOSUM62 scoring matrix (see Henikoff and Henikoff (1992) Proc. Natl. Acad. Sci. USA 89: 10915-10919), alignments (B) of 50, expectations (E) of 10, M=5, N=4, and a comparison of both strands.
[0136] The BLAST algorithm performs a statistical analysis of the similarity between two sequences; see, e.g., Karlin and Altschul (1993) Proc. Natl. Acad. Sci. USA 90:5873-5787. One similarity measure provided by the BLAST algorithm is the smallest sum probability (P(N)), which provides an indication of the probability that a match between two nucleotide or amino acid sequences will occur by chance. For example, a sequence is considered similar to another sequence if the smallest sum probability in a comparison of a first sequence to a second sequence is less than about 1, preferably less than about 0.1, more preferably less than about 0.01, and most preferably less than about 0.001.
[0137] In one embodiment, due to the redundancy of the genetic code, the variant sequence can be different from the specific sequence given in the sequence table. The DNA code has 4 main nucleic acid residues (A, T, C and G), and uses these residues to "spell" three-letter codons, which represent the amino acids in the proteins encoded in the genes of the organism. The linear sequence of the codons along the DNA molecule is translated into the linear sequence of amino acids in the proteins encoded by these genes. The code is highly degenerate, with 61 codons encoding 20 natural amino acids and 3 codons representing "stop" signals. Therefore, most amino acids are encoded by more than one codon-in fact, several amino acids are encoded by four or more different codons. Therefore, the variant polynucleotide of the present invention can encode the same polypeptide sequence as the polypeptide sequence encoded by another polynucleotide of the present invention, but because different codons are used to encode the same amino acid, different nucleic acid sequences can be used. Codons can be optimized to improve the expression level of the encoded protein in the target cell compared to using an unchanged sequence.
[0138] The virus of the present invention preferably comprises GM-CSF. The sequence of the gene encoding GM-CSF may be codon-optimized to increase the expression level of the corresponding protein in target cells compared to the case where the unaltered sequence is used.
[0139] The virus of the present invention preferably comprises one or more immune costimulatory pathway activating molecules and / or one or more genes encoding immune costimulatory pathway activating molecules. Immune costimulatory pathway activating molecules include proteins and nucleic acid molecules (e.g., aptamer sequences). Examples of immune costimulatory pathway activating molecules include CD40 ligands, GITR ligands, 4-1-BB ligands, OX40 ligands, ICOS ligands, flt3 ligands, TL1A, CD30 ligands, CD70 and single-chain antibodies targeting the respective receptors of these molecules (CD40, GITR, 4-1-BB, OX40, ICOS, flt3, DR3, CD30, CD27).
[0140] Activators of immune co-stimulatory pathways include mutant or wild-type, soluble, secreted and / or membrane-bound ligands, and agonistic antibodies including single-chain antibodies. The virus of the present invention preferably encodes one or more of CD40L, ICOSL, 4-1-BBL, GITRL or OX40L.
[0141] The virus of the present invention may encode one or more immune co-stimulatory pathway activating molecules, preferably 1, 2, 3 or 4 immune co-stimulatory pathway activating molecules, and more preferably 1 or 2 immune co-stimulatory pathway activating molecules.
[0142] The sequence of the gene encoding the immune co-stimulatory activating molecule can be codon-optimized to increase the expression level of the corresponding protein in the target cell compared to when the unaltered sequence is used.
[0143] In addition to CTLA-4 inhibitors and GM-CSF and / or immune co-stimulatory pathway activating molecules, the virus of the present invention may also include one or more additional heterologous genes. In a preferred embodiment, the virus may also include a fusogenic protein, such as GALVR-.
[0144] Fusogenic proteins can be any heterologous protein that can promote the fusion of cells infected by the virus of the present invention with another cell. Fusogenic proteins, preferably wild-type or modified viral glycoproteins (i.e., modified to increase their fusogenic properties), are proteins that can induce intercellular fusion (syncytium formation) of cells in which they are expressed. Examples of fusogenic glycoproteins include VSV-G, syncytin-1 (from human endogenous retrovirus-W (HERV-W)) or syncytin-2 (from HERVFRDE1), paramyxovirus SV5-F, measles virus-H, measles virus-F, RSV-F, glycoproteins from retroviruses or lentiviruses, such as gibbon ape leukemia virus (GALV), murine leukemia virus (MLV), Mason-Pfizer monkey virus (MPMV) and equine infectious anemia virus (EIAV) glycoproteins (wherein the R transmembrane peptide is removed (R-form)). In a preferred embodiment, the fusogenic protein is from GALV and the R-peptide has been removed (GALV-R-).
[0145] The viruses of the invention may optionally comprise multiple copies of a fusogenic protein encoding gene, preferably 1 or 2 copies.The viruses may comprise two or more different fusogenic proteins, including any of the fusogenic proteins listed above.
[0146] The fusogenic protein optionally expressed by the viruses of the invention can be the same as a naturally occurring protein, or can be a modified protein.
[0147] Fusogenic protein encoding gene (fusogenic gene) can have naturally occurring nucleic acid sequence or modified sequence.For example, the sequence of fusogenic gene can be modified to increase the fusogenic property of the encoded protein, or provide codon optimization, thereby improving the expression efficiency of the encoded protein.
[0148] The present invention also provides a virus expressing at least three heterologous genes, such as poxvirus or HSV, preferably HSV1, wherein each of the three heterologous genes is driven by a different promoter selected from the group consisting of CMV promoter, RSV promoter, EF1a promoter, SV40 promoter and retroviral LTR promoter. For example, the virus can express four heterologous genes, wherein each of the four heterologous genes is driven by a different promoter selected from the group consisting of CMV promoter, RSV promoter, EF1a promoter, SV40 promoter and retroviral LTR promoter. Retroviral LTR is preferably from MMLV. The heterologous genes can be terminated by a polyadenylation sequence. The polyadenylation sequences can be the same or different. Preferably, each heterologous gene is terminated by a different polyadenylation sequence, preferably selected from the group consisting of BGH, SV40, HGH and RBG polyadenylation sequences. The present invention also provides a virus, such as a poxvirus or HSV, preferably HSV1, which expresses at least three heterologous genes, wherein each of the three heterologous genes is terminated by a different polyadenylation sequence selected from the group consisting of BGH, SV40, HGH and RBG polyadenylation sequences. For example, the virus can express four heterologous genes terminated by each of the BGH, SV40, HGH and RBG polyadenylation sequences, respectively.
[0149] The at least three heterologous genes can be, for example, selected from CTLA-4 inhibitors, genes encoding GM-CSF, genes encoding immune co-stimulatory pathway activation molecules, and fusion-promoting genes. Examples of three heterologous genes are CTLA-4 inhibitors, genes encoding GM-CSF, and genes encoding immune co-stimulatory pathway activation molecules; CTLA-4 inhibitors, genes encoding GM-CSF, and fusion-promoting genes; and CTLA-4 inhibitors, genes encoding immune co-stimulatory pathway activation molecules, and fusion-promoting genes. For example, the four heterologous genes can be CTLA-4 inhibitors, genes encoding GM-CSF, genes encoding immune co-stimulatory pathway activation molecules, and fusion genes. The three or four heterologous genes may include, for example, two or more genes encoding immune co-stimulatory pathway activation molecules and / or two or more fusion-promoting genes.
[0150] In one embodiment, the promoters controlling the expression of the three heterologous genes are CMV, RSV and MMLV promoters. For example, a preferred virus may contain a GM-CSF gene under the control of a CMV promoter, a GALV gene under the control of a RSV promoter, and a CTLA-4 inhibitor under the control of a MMLV promoter.
[0151] In one embodiment, the polyadenylation sequences terminating the at least three heterologous genes are SV40, BGH and RBG polyadenylation sequences. Controlling the expression of the three heterologous genes are CMV, RSV and MMLV promoters. For example, a preferred virus may include a GM-CSF gene terminated by a BGH polyadenylation sequence, a GALV gene terminated by a SV40 polyadenylation sequence, and a CTLA-4 inhibitor terminated by a RGB polyadenylation sequence.
[0152] Any combination of various promoters and polyadenylation sequences can be used with any heterologous gene. For example, a preferred virus may contain the GM-CSF gene under the control of the CMV promoter and terminated by the BGH polyadenylation sequence, the GALV gene under the control of the RSV promoter and terminated by the SV40 polyadenylation sequence, and the CTLA-4 inhibitor under the control of the MMLV promoter and terminated by the RGB polyadenylation sequence.
[0153] Virus Generation
[0154] The virus of the present invention is constructed using methods disclosed in the art. For example, plasmids (for smaller viruses and single and multiple genome component RNA viruses) or BACs (for larger DNA viruses, including herpes viruses) encoding the viral genome to be packaged (including genes encoding fusogenic and immunostimulatory molecules under appropriate regulatory control) can be constructed by standard molecular biological techniques and transfected into permissive cells from which recombinant viruses can be recovered.
[0155] Alternatively, in a preferred embodiment, a plasmid containing a DNA region flanking the expected insertion site can be constructed and then co-transfected with viral genomic DNA into permissive cells so that homologous recombination occurs between the target insertion site flanking region in the plasmid and the same region in the parental virus. The recombinant virus can then be selected and purified by the loss or addition of function (insertion or deletion of a plasmid for modification, such as insertion or deletion of a marker gene such as GFP or lacZ from the parental virus at the expected insertion site). In a most preferred embodiment, the insertion site is the ICP34.5 locus of HSV, so the plasmid used for the operation contains HSV sequences flanking the insertion site, between which are expression cassettes encoding GM-CSF and immune co-stimulatory pathway activation molecules. In this case, the parental virus may contain a cassette encoding GFP that replaces ICP34.5, and recombinant virus plaques are selected by the loss of GFP expression. In a most preferred embodiment, the US11 gene of HSV is also expressed as an IE gene. This can be achieved by deleting the ICP47 coding region or by other means.
[0156] The CTLA-4 inhibitor and optionally the GM-CSF coding sequences as well as the immune co-stimulatory pathway activator coding sequences and / or additional protein coding sequences (such as sequences encoding fusogenic proteins such as GALVR-) are inserted into the viral genome under appropriate regulatory control. Depending on the species and insertion site, this may be under the regulatory control of the native promoter of the viral species of the invention used, or preferably under the control of a heterologous promoter. Suitable heterologous promoters include mammalian promoters such as the IEF2a promoter or the actin promoter. More preferred are strong viral promoters such as the CMV IE promoter, RSV LTR, MMLV LTR, other retroviral LTR promoters, or promoters derived from SV40. Preferably, each exogenous gene (e.g., encoding GM-CSF and immune co-stimulatory pathway activator) will be under the control of separate promoters, but may also be expressed from a single RNA transcript, for example by inserting an internal ribosome entry site (IRES) between the protein coding sequences. RNA derived from each promoter typically terminates with a polyadenylation sequence (e.g., a mammalian sequence such as the bovine or human growth hormone (BGH) poly A sequence, a synthetic polyadenylation sequence, the rabbit β-globin polyadenylation sequence, or a viral sequence such as the SV40 early or late polyadenylation sequence).
[0157] Each heterologous gene in the virus is usually under the control of a promoter. The promoters controlling the expression of heterologous genes can be the same or different. For example, anti-CTLA-4 and one or more of the genes encoding GM-CSF, fusogenic genes, and immune co-stimulatory pathway activating molecules can each be under the control of a CMV promoter, a RSV promoter, an EF1a promoter, a SV40 promoter, or a retroviral LTR promoter. Alternatively, for example, anti-CTLA-4 can be under the control of a retroviral LTR promoter such as an MMLV promoter, the GM-CSF gene can be under the control of a CMV promoter, and / or a fusogenic gene such as GALVR- can be under the control of an RSV promoter.
[0158] Pharmaceutical composition
[0159] The present invention provides a pharmaceutical composition comprising a virus and a pharmaceutically acceptable carrier or diluent. Suitable carriers and diluents include isotonic saline solutions, such as phosphate buffered saline. The composition may also include other ingredients, such as sugars or proteins, to improve properties, such as the stability of the product. Alternatively, a lyophilized formulation may be used, which is reconstituted in a pharmaceutically acceptable carrier or diluent before use.
[0160] If necessary, the choice of carrier is generally a function of the composition delivery route. In the present invention, the composition can be formulated for any suitable route and mode of administration. Pharmaceutically acceptable carriers or diluents are those that can be used for compositions suitable for intratumoral administration, intravenous / intraarterial administration, intracerebral administration, or administration in a body cavity (e.g., bladder, pleural cavity, or by intraperitoneal administration). The composition can be in any suitable form, preferably in liquid form.
[0161] The invention also provides an article of manufacture comprising the virus of the invention in a sterile vial, ampoule or syringe.
[0162] Medical uses / treatments
[0163] The present invention provides a virus of the present invention for use in treating a human or animal body by therapy, in particular for a method of treating cancer. Cancer is typically present in mammals, preferably in humans. The virus kills infected tumor cells by lysis and by fusing infected tumor cells to each other. The virus of the present invention also triggers a systemic anti-tumor immune response, enhanced by the expression of CTLA-4 inhibitors and optionally GM-CSF and immune co-stimulatory pathway activating molecules, which also kill cancer cells.
[0164] The invention also provides a method of treating cancer, comprising administering to an individual in need thereof a therapeutically effective amount of a virus of the invention.
[0165] The present invention further provides use of the virus of the present invention in preparing a medicament for treating cancer.
[0166] The viruses of the present invention are particularly suitable for treating any solid tumor, including any adenocarcinoma, carcinoma, melanoma or sarcoma.

[0167] The viruses of the invention can be used to treat malignant tumors, including tumors that have metastasized from the original tumor site. In this embodiment, the virus can be administered to the primary tumor or one or more secondary tumors.
[0168] The virus of the present invention can be administered in combination with other therapeutic agents (including chemotherapy, targeted therapy, immunotherapy (including immune checkpoint blockade, i.e., administration of one or more antagonists of immune co-inhibitory pathways, and / or one or more agonists of immune co-stimulatory pathways)), and / or in combination with radiotherapy and / or in combination with any combination of these therapies. The therapeutic agent is preferably an anticancer agent.
[0169] The viruses of the invention can be administered in combination with a second virus, such as a second oncolytic virus.
[0170] For example, the therapeutic agent may comprise an immunogen (including a recombinant or naturally occurring antigen, including such an antigen or a combination of antigens delivered with DNA or RNA encoding it / them) to further stimulate an immune response, such as a cellular or humoral immune response, against tumor cells, particularly tumor neoantigens. The therapeutic agent may be an agent intended to increase or enhance the immune response, such as a cytokine, an agent intended to inhibit an immune checkpoint pathway or stimulate an immune enhancement pathway, or an agent that inhibits the activity of regulatory T cells (Treg) or myeloid-derived suppressor cells (MDSC).
[0171] The therapeutic agent can be a medicament known for existing cancer treatment. The therapeutic agent can be radiotherapy or a chemotherapeutic agent. The therapeutic agent can be selected from cyclophosphamide, alkylating agents such as cisplatin or melphalan, plant alkaloids and terpenoids such as vincristine or paclitaxel (Taxol), antimetabolites such as 5-fluorouracil, topoisomerase inhibitors type I or II such as camptothecin or doxorubicin, cytotoxic antibiotics such as actinomycin, anthracyclines such as epirubicin, glucocorticoids such as triamcinolone, protein, inhibitors of DNA and / or RNA synthesis such as methotrexate and dacarbazine, histone deacetylase (HDAC) inhibitors or any other chemotherapeutic agents.
[0172] The therapeutic agent can be one or a combination of an immunotherapeutic agent or an immunomodulator, such as a TLR agonist; a drug that downregulates T-regulatory cells, such as cyclophosphamide; or an agent intended to block immune checkpoints or stimulate immune enhancement pathways, including but not limited to monoclonal antibodies, such as CTLA-4 inhibitors, PD-1 inhibitors, PD-L1 inhibitors, LAG-3 inhibitors, TIM-3 inhibitors, VISTA inhibitors, CSF1R inhibitors, IDO inhibitors, CEACAM1 inhibitors, GITR agonists, 4-1-BB agonists, KIR inhibitors, SLAMF7 inhibitors, OX40 agonists, CD40 agonists, ICOS agonists or CD47 inhibitors. In a preferred embodiment, the therapeutic agent is a CTLA-4 inhibitor, such as an anti-CTLA-4 antibody, a PD1 inhibitor, such as an anti-PD-1 antibody or a PD-L1 inhibitor, such as an anti-PD-L1 antibody. Such inhibitors, agonists and antibodies can be produced and tested by standard methods known in the art.
[0173] Immunotherapeutics may also include bispecific antibodies, cell-based therapies based on dendritic cells, NK cells, or engineered T cells (such as CAR-T cells or T cells expressing engineered T cell receptors). Immunotherapeutics also include agents that target specific genetic mutations occurring in tumors, agents designed to induce immune responses against specific tumor antigens or combinations of tumor antigens (including new antigens), and / or agents designed to activate the STING / cGAS pathway, TLRs, or other innate immune responses and / or inflammatory pathways, including intratumoral agents.
[0174] For example, the viruses of the invention can be used in combination with dacarbazine, a BRAF inhibitor and / or a PD1 or PD-L1 blocker to treat melanoma; in combination with paclitaxel, doxorubicin, vinorelbine, cyclophosphamide and / or gemcitabine to treat breast cancer; in combination with 5-fluorouracil and optionally leucovorin, irinotecan and / or oxaliplatin to treat colorectal cancer; in combination with taxol, carboplatin, vinorelbine and / or gemcitabine, PD-1 or PD-L1 blockade to treat lung cancer; in combination with cisplatin and / or radiation therapy to treat head and neck cancer.
[0175] The therapeutic agent may be an inhibitor of the indoleamine 2,3-dioxygenase (IDO) pathway. Examples of IDO inhibitors include epacadostat (INCB024360), 1-methyl-tryptophan, indoximod (1-methyl-D-tryptophan), GDC-0919 or F001287.
[0176] The mechanism of action of IDO in suppressing anti-tumor immune response can also suppress the immune response produced after oncolytic virus treatment. IDO expression is induced by Toll-like receptor (TLR) activation and interferon-γ (both of which can be caused by oncolytic virus infection). An embodiment of using oncolytic virus therapy to treat cancer includes oncolytic virus, and optionally GM-CSF and / or immune costimulatory pathway activation molecules and / or one or more other protein coding sequences (such as sequences encoding fusion-promoting proteins such as GALVR-) (including viruses expressing CTLA-4 inhibitors) and inhibitors of IDO pathways and optionally another antagonist of immune co-inhibitory pathways and / or one or more agonists of immune costimulatory pathways (including those targeting PD-1 and / or PD-L1) combination.
[0177] When therapeutic agents and / or radiotherapy are used in combination with the virus of the present invention, the administration of the virus and therapeutic agents and / or radiotherapy can be simultaneous or separated by time. The composition of the present invention can be administered before, simultaneously with, or after the therapeutic agent or radiotherapy. The method for treating cancer may include multiple administrations of the virus and / or therapeutic agent and / or radiotherapy of the present invention. In a preferred embodiment, in combination with immune checkpoint blockade or other immunoenhancers, the virus of the present invention is administered once or multiple times, and then the immune checkpoint blocker is administered simultaneously or one or more other immunoenhancers are administered afterwards, or without prior administration of the virus of the present invention, the virus of the present invention is administered simultaneously with the immune checkpoint blocker or one or more other immunoenhancers.
[0178] The virus of the present invention can be administered to a subject by any suitable route. Typically, the virus of the present invention is administered by direct intratumoral injection. Intratumoral injection includes direct injection into superficial skin, subcutaneous or lymph node tumors, and imaging guidance (including CT, MRI or ultrasound) injection into deeper or more difficult to locate sites, including in internal organs and other places. The virus can be administered into a body cavity, for example, into the pleural cavity, in the bladder, or by intraperitoneal administration. The virus may be injected into a blood vessel (preferably a blood vessel supplying the tumor).
[0179] Can use multiple known approaches and technology to human or animal subjects in vivo administration can be with the therapeutic agent of the virus combination of the present invention.For example, composition can be provided as injection, suspension or emulsion, and use conventional needle and syringe or use liquid jet injection system by parenteral, subcutaneous, oral, epidermal, intradermal, intramuscular, intraarterial, intraperitoneal, intravenous injection administration.Composition can be topically applied to skin or mucosal tissue (such as nasal, intratracheal, intestinal, sublingual, rectal or vaginal), or provide with the finely dispersed spray suitable for breathing or pulmonary administration.In a preferred embodiment, composition is administered by intravenous infusion, oral or directly into tumor.
[0180] The virus and / or therapeutic agent can be administered to the subject in an amount compatible with the therapeutically effective dosage composition. The administration of the virus of the present invention is for "treatment" purposes. As used herein, the term "therapeutic" or "treatment" includes any one or more of the following as its goal: preventing any metastasis or further metastasis from occurring; alleviating or eliminating symptoms; reducing or completely eliminating tumors or cancers, increasing the time to reach patient cancer progression; increasing the time to recurrence after treatment; or prolonging survival time.
[0181] Therapeutic treatment may be administered to stage I, II, III or IV cancer, preferably stage II, III or IV, more preferably stage III or IV cancer, before or after surgical intervention (i.e., after tumor recurrence after surgery or incomplete resection thereof), preferably before any surgical intervention (to resect primary or recurrent / metastatic disease), or after surgery or after recurrence after incomplete surgical resection of the disease (i.e., when there is residual tumor).
[0182] Therapeutic treatment may be performed after direct injection of the viral composition into the target tissue, which may be a tumor, a body cavity or a blood vessel. As a guide, the amount of virus administered in the case of HSV is between 10 4 Up to 10 10 pfu, preferably 10 5 Up to 10 9 In the case of HSV, an initial lower dose (e.g., 10 4 Up to 10 7 pfu) to seroconvert patients seronegative for HSV and boost in those seropositive, followed by higher doses (e.g., 10 6 Up to 10 9 pfu). Typically, up to 20 ml of a pharmaceutical composition consisting essentially of the virus and a suitable pharmaceutically acceptable carrier or diluent may be used for direct injection into a tumor, or up to 50 ml may be used for administration into a body cavity (the composition may be further diluted into a suitable diluent prior to administration) or into the bloodstream. However, for some oncolytic therapy applications, larger or smaller volumes may also be used, depending on the tumor and the route and site of administration.
[0183] The administration route and dosage described are intended only as a guide, as a skilled practitioner will be able to easily determine the optimal administration route and dosage. The dosage can be determined according to various parameters, in particular according to the location of the tumor, the size of the tumor, the age, weight and condition of the patient to be treated, and the administration route. Preferably, the virus is administered by direct injection into the tumor or in a body cavity. The virus can also be administered by direct injection into a blood vessel. The optimal administration route will depend on the location and size of the tumor. Multiple doses may be required to achieve an immunological or clinical effect, and if necessary, the dosage is usually administered at intervals of 2 days to 12 weeks, preferably at intervals of 3 days to 3 weeks. Repeated doses of up to 5 years or more can be given, preferably up to one month to two years, depending on the response rate of the tumor type being treated and the response of the specific patient and any combination therapy that may also be given.
[0184] The following examples illustrate the invention.
[0185] Example 1. Construction of the virus of the present invention
[0186] The viral species used to exemplify the present invention is HSV, in particular HSV1.
[0187] A diagram of the plasmids used is shown in Figure 2. A diagram of the viruses is shown in Figure 1. All viruses were constructed using HSV1 strain RH018A. Plasmids used for virus construction were generated by a combination of gene synthesis and subcloning performed by Genscript Inc.
[0188] A virus expressing anti-mouse CTLA4 as well as mouse GM-CSF and GALV was constructed by co-transfecting plasmid 77 with virus 16 DNA to insert GFP into virus 16 (by selecting for GFP-expressing plaques) to produce virus 25. GFP was then knocked out of virus 25 by co-transfecting virus 25 DNA with plasmid 119. This produced virus 27.
[0189] A virus expressing anti-human CTLA4 as well as human GM-CSF and GALV was constructed by co-transfecting plasmid 78 with virus 17 DNA to insert GFP into virus 17 (by selecting for GFP-expressing plaques) to produce virus 29. GFP was then knocked out of virus 29 by co-transfecting virus 29 DNA with plasmid 122. This produced virus 31.
[0190] Viruses expressing anti-mouse CTLA-4 and co-stimulatory ligands as well as mouse GM-CSF and GALV were constructed by co-transfecting a plasmid encoding GFP driven by the SV40 promoter between the mouse GM-CSF coding sequence and the anti-mouse CTLA-4 coding sequence with virus 27. GFP was then knocked out from the resulting virus by replacing GFP with plasmids encoding each individual mouse co-stimulatory ligand.
[0191] Viruses expressing anti-human CTLA-4 and co-stimulatory ligands as well as human GM-CSF and GALV were constructed by co-transfecting a plasmid encoding GFP driven by the SV40 promoter between the human GM-CSF coding sequence and the anti-human CTLA-4 coding sequence with virus 31. GFP was then knocked out from the resulting virus by replacing GFP with plasmids encoding each individual human co-stimulatory ligand.
[0192] Figure 4 Western blot demonstrating expression of anti-mouse CTLA-4 from virus 27 is shown.
[0193] Example 2. Effect of combined expression of GALV, GM-CSF and anti-CTLA4 from oncolytic viruses
[0194] The utility of the present invention was demonstrated in the following manner: A20 cells were administered to both flanks of Balb / c mice and A20 tumors were allowed to grow to approximately 0.5 cm in diameter.
[0195] Groups of mice were then administered (3 times per week for 1 week into only one flank (right tumor) of each mouse) the following treatments:
[0196] -50 μl vehicle (1 group);
[0197] -50 μl of 10 6 pfu / ml of HSV inserted only into mouse GM-CSF and GALVR- (virus 16);
[0198] -50 μl of 10 6 pfu / ml of GALVR-, mouse GM-CSF, and anti-mouse CTLA-4 antibody-inserted HSV (virus 27);
[0199] The effect on tumor growth was then observed for up to one month. The viral dose used was 5x10 4 pfu (50ul, 1x10 6 pfu / ml), administered three times in one week. This viral dose level was subtherapeutic for virus 16-uninjected tumors, allowing for a clear benefit from the delivery of other molecules encoded by virus 27. Figure 5 and Figure 6 Superior tumor control and shrinkage in uninjected tumors with anti-CTLA-4 expressing virus compared to virus 16 not expressing CTLA-4 was shown.
[0200] Example 3. Effect of combined expression of GALV, GM-CSF and anti-CTLA4 and anti-PD-1 from oncolytic viruses
[0201] A20 cells were administered to both flanks of Balb / c mice, and A20 tumors were allowed to grow to approximately 0.5 cm in diameter.
[0202] Groups of mice (10 per group) were then administered (3 times per week, into one flank only of each mouse, for 1 week) the following treatments:
[0203] - 50 μl vehicle;
[0204] - intraperitoneal anti-mouse PD1 (Bioxcell RMP-1-14 10 mg / kg, once every three days);
[0205] -50 μl of 10 7 pfu / ml of GALVR-inserted HSV (virus 27), mouse GM-CSF, and anti-mouse CTLA-4 antibody
[0206] -50 μl of 10 7 pfu / ml of GALVR-, mouse GM-CSF and anti-mouse CTLA-4 antibody (Virus 27) and intraperitoneal anti-mouse PD1 (10 mg / kg every 3 days) HSV (Group 3).
[0207] The effects on tumor growth were then observed for up to 80 days. When the viral therapy was combined with anti-PD1 therapy, there was excellent tumor control and shrinkage in both injected and uninjected tumors. This data is shown in Figure 7 shown.
[0208] Example 4. Effects of combined expression of GALV, GM-CSF and anti-human CTLA4 from oncolytic viruses alone and in combination with anti-PD-1
[0209] MC38 cells were administered to the flanks of C57BL / 6 mice engineered by gene editing to express human CTLA-4 instead of mouse CTLA-4. This made the mice susceptible to anti-human CTLA-4 antibodies such as ipilimumab. MC38 tumors were grown to approximately 0.5 cm in diameter.
[0210] Groups of mice (10 per group) were then administered (3 times per week, into one flank only of each mouse, for 2 weeks) the following treatments:
[0211] - 50 μl vehicle;
[0212] -50 μl of 10 8 pfu / ml of virus 17 (i.e., expressing hGM-CSF and GALV);
[0213] -50 μl of 10 8pfu / ml of virus 31 (i.e., expressing hGM-CSF, GALV, and anti-human CTLA-4);
[0214] -50 μl of 10 8 pfu / ml of virus 17 and intraperitoneal anti-mouse PD1 (10 mg / kg every 3 days);
[0215] -50 μl of 10 8 pfu / ml of virus and intraperitoneal anti-mouse PD1 (10 mg / kg every 3 days).
[0216] The effects on tumor growth were then observed for up to 35 days. Excellent tumor control and shrinkage were observed in tumors injected with viruses expressing anti-human CTLA-4, an effect that was further enhanced when combined with anti-PD1. When treatment with either virus was combined with anti-PD1 treatment, excellent tumor control and shrinkage were observed in non-injected tumors. The improvement was even more pronounced with the virus expressing anti-CTLA4. This data is shown in Figure 8 middle.
[0217] Example 5. Effect of combined expression of GALV, GM-CSF and anti-CTLA4 and anti-PD-1 from oncolytic viruses
[0218] A20 cells were administered to both flanks of Balb / c mice, and A20 tumors were allowed to grow to approximately 0.5 cm in diameter.

[0220] -50 μl vehicle (1 group);
[0221] - intraperitoneal anti-mouse PD1 (Bioxcell RMP-1-14 10 mg / kg, once every three days);
[0222] -50 μl of 10 5 pfu / ml, 10 6 pfu / ml or 10 7 pfu / ml of HSV inserted only into mouse GM-CSF and GALVR- (3 groups);

[0224] -50 μl of 10 5 pfu / ml, 10 6 pfu / ml or 10 7 pfu / ml of HSV inserted only into mouse GM-CSF and GALVR- and intraperitoneal anti-mouse PD1 (10 mg / kg, once every three days) (3 groups);
[0225] -50 μl of 10 5 pfu / ml, 10 6 pfu / ml or 10 7 pfu / ml of HSV inserted into GALVR-, mouse GM-CSF and anti-mouse CTLA-4 antibody and intraperitoneal anti-mouse PD1 (10 mg / kg, once every three days) (3 groups).
[0226] The effects on tumor growth were then observed for up to one month. Superior tumor control and shrinkage was observed in both injected and uninjected tumors with the anti-CTLA-4 expressing virus compared to the other group, including through an improved dose response curve, which was further enhanced when combined with anti-PD1 therapy.
[0227] Example 6. Effect of combined expression of GALV, GM-CSF and anti-human CTLA4 from oncolytic virus itself and in combination with anti-PD-1
[0228] MC38 cells were administered to the flanks of C57BL / 6 mice engineered by gene editing to express human CTLA-4 instead of mouse CTLA-4. This made the mice susceptible to anti-human CTLA-4 antibodies such as ipilimumab. MC38 tumors were grown to approximately 0.5 cm in diameter.
[0229] Groups of mice (10 per group) were then administered (3 times per week, into one flank only of each mouse, for 2 weeks) the following treatments:
