[0024] After reading this specification, it will be apparent to those skilled in the art how to implement the present invention in various alternative embodiments and alternative applications. However, all various embodiments of the present invention will not be described herein. It should be understood that the embodiments presented here are presented only by way of example and not limitation. Therefore, these detailed descriptions of various alternative embodiments should not be interpreted as limiting the scope or breadth of the present invention as described below.
[0025] Before disclosing and describing the present invention, it is to be understood that the aspects described below are not limited to specific compositions, methods of making such compositions, or uses thereof, as these may of course vary. It is also to be understood that the terminology used herein is for describing particular aspects only and is not intended to be limiting.
[0026] The detailed description of the present invention is divided into different parts only for the convenience of the reader, and the disclosure found in any part can be combined with the disclosure in another part. For the convenience of the reader, titles or subtitles can be used in the specification, which are not intended to affect the scope of the present invention.
[0027] I. Definitions
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by ordinary technicians in the field to which the present invention belongs. In this specification and the following claims, a number of terms will be mentioned, which should be defined as having the following meanings:
[0029] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the present invention. As used herein, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms as well.
[0030] "Optional" or "optionally" means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where the event or circumstance occurs and instances where it does not.
[0031] The term "about", when used in front of a numerical designation (e.g., temperature, time, amount, concentration, etc., including ranges), indicates an approximate value that may vary by (+) or (-) 10%, 5%, 1%, or any subrange or subvalue therebetween. Preferably, the term "about", when used with respect to the amount of a dosage, means that the dosage may vary by + / - 10%.
[0032] "Comprising" is intended to mean that compositions and methods include the recited elements, but not excluding other elements. "Consisting essentially of" when used to define compositions and methods will mean excluding other elements having any essential significance to the combination for the stated use. Thus, a composition consisting essentially of the elements as defined herein will not exclude other materials or steps that do not materially affect one or more basic and novel characteristics of the claimed invention. "Consisting of" shall mean excluding elements and substantial method steps that exclude more than trace amounts of other ingredients. Embodiments defined by each of these transition terms are within the scope of the present invention.
[0033] The term "disease" or "condition" refers to the state or health of a patient or subject that can be treated with the compounds or methods provided herein. The disease can be an autoimmune disease. The disease can be an inflammatory disease. The disease can be an infectious disease.
[0034] The term "treating" or "treatment" refers to any indicator of successful treatment or improvement of an injury, disease, lesion, or condition, including any objective or subjective parameter, such as elimination; relief; reduction of symptoms or making an injury, lesion, or condition more tolerable to the patient; slowing the rate of degeneration or decline; making the final point of degeneration less debilitating; improving the patient's physical and mental health. Treatment or improvement of symptoms can be based on objective or subjective parameters; including the results of physical examinations, neuropsychiatric tests, and / or psychiatric assessments. The term "treatment" and its variations can include preventing an injury, pathology, condition, or disease. In embodiments, treatment is prevention. In embodiments, treatment does not include prevention.
[0035] "Treating" or "treatment" as used herein (and as is well understood in the art) also broadly encompasses any method for obtaining a beneficial or desired result (including a clinical result) in a subject's condition. Beneficial or desired clinical results may include, but are not limited to, alleviation or improvement of one or more symptoms or symptoms, alleviation of the extent of the disease, stabilization (i.e., not worsening) of the disease state, prevention of disease transmission or spread, delay or slowing of disease progression, improvement or alleviation of the disease state, reduction of disease recurrence, and alleviation (whether partial or total, and whether detectable or undetectable). In other words, "treatment" as used herein includes any cure, improvement, or prevention of a disease. Treatment may prevent the occurrence of a disease; inhibit the spread of a disease; alleviate symptoms of a disease (e.g., eye pain, seeing halos, red eyes, extremely high intraocular pressure), completely or partially remove the underlying cause of the disease, shorten the duration of the disease, or a combination of these.
[0036] As used herein, "treating" and "treatment" include preventive treatment. The treatment method includes administering a therapeutically effective amount of an active agent to a subject. The administration step may consist of a single administration, or may include a series of administrations. The length of the treatment cycle depends on a variety of factors, such as the severity of the disorder, the age of the patient, the concentration of the active agent, the activity of the composition used for treatment, or a combination thereof. It should also be understood that the effective dose of the active agent used for treatment or prevention may increase or decrease over the course of a particular treatment or prevention regimen. Changes in dosage may occur and become apparent through standard diagnostic assays known in the art. In some cases, long-term administration may be required. For example, the composition is administered to the subject in an amount and duration sufficient to treat the patient. In many aspects, "treating" or "treatment" is not a preventive treatment.
[0037] The term "prevention" refers to reducing the occurrence (or recurrence) of disease symptoms in a patient. As indicated above, prevention can be complete (ie, no detectable symptoms) or partial, such that fewer symptoms are observed than would be possible without treatment.
[0038] "Patient", "subject" or "subject in need" refers to a living organism that suffers from or is susceptible to a disease or condition that can be treated by administering a pharmaceutical composition as provided herein. Non-limiting examples include humans, other mammals, cattle, rats, mice, dogs, monkeys, goats, sheep, pigs, deer and other non-mammals. In some embodiments, the patient is a human. In embodiments, the human is a pediatric patient. In embodiments, the patient is a domestic animal (e.g., goats, sheep, cattle, horses, etc.). In embodiments, the patient is a companion animal, including but not limited to dogs, cats, rodents (mice, rats, gerbils, hamsters, guinea pigs, chinchillas, etc.), rabbits, ferrets, etc.
[0039] An "effective amount" is an amount sufficient to achieve the stated purpose of a compound relative to the absence of the compound (e.g., to achieve the effect for which it is administered, to treat a disease, or to alleviate one or more symptoms of a disease or condition). An example of an "effective amount" is an amount sufficient to facilitate the treatment, prevention, or alleviation of one or more symptoms of a disease, which may also be referred to as a "therapeutically effective amount." "Allowance" of one or more symptoms (and grammatical equivalents of the phrase) means a reduction in the severity or frequency of the one or more symptoms, or the elimination of the one or more symptoms. The exact amount will depend on the purpose of the treatment, and will be determined by one skilled in the art using known techniques (see, e.g., Lieberman, Pharmaceutical Dosage Forms (Volumes 1-3, 1992); Lloyd, The Art, Science and Technology of Pharmaceutical Compounding (1999); Pickar, Dosage Calculations (1999); and Remington: The Science and Practice of Pharmacy, 20th edition, 2003, Gennaro ed., Lippincott, Williams & Wilkins).
[0040] As is well known in the art, therapeutically effective amounts for humans can also be determined from animal models. For example, a dose for humans can be formulated to achieve a dose that has been found to be effective in animals. As described herein, the dose in humans can be adjusted by monitoring effectiveness and adjusting the dose up or down. It is well within the capabilities of ordinary technicians to adjust the dose to achieve maximum efficacy in humans based on the methods described herein and other methods.
[0041] As used herein, the term "therapeutically effective amount" refers to the amount of a therapeutic agent sufficient to improve a condition as described above. For example, for a given parameter, a therapeutically effective amount will show an increase or decrease of at least 5%, 10%, 15%, 20%, 25%, 40%, 50%, 60%, 75%, 80%, 90%, or at least 100%. The therapeutic efficacy can also be expressed as a "fold" increase or decrease. For example, a therapeutically effective amount can have an effect of at least 1.2 times, 1.5 times, 2 times, 5 times, or more relative to a control.
[0042] The dosage may vary depending on the needs of the patient and the composition used. In the context of the present disclosure, the dosage administered to the patient should be sufficient to produce a beneficial therapeutic response in the patient over time. The size of the dosage will also be determined by the presence, nature and extent of any adverse side effects. The determination of the appropriate dosage for a specific situation is within the skill range of the practitioner. In some embodiments, treatment begins with a smaller dose that is lower than the optimal dose of the composition. Thereafter, the dosage is increased in small increments until the best effect is achieved in a variety of situations. The amount and interval of the dosage can be adjusted separately to provide an effective level of the administered composition for the specific clinical indication being treated. This will provide a treatment regimen commensurate with the severity of the subject's disease state.
[0043] As used herein, the term "administering" means oral administration, administration as a suppository, topical contact, intravenous administration, parenteral administration, intraperitoneal administration, intramuscular administration, intralesional administration, intrathecal administration, intraventricular administration, intrapleural administration, intraparenchymal administration, intranasal administration or subcutaneous administration, or implanting a sustained release device (e.g., micro-osmotic pump) to a subject. Administration is carried out by any route, including parenteral routes and transmucosal (e.g., buccal, sublingual, palate, gingival, nose, vagina, rectum or transdermal) routes. Parenteral administration includes, for example, intravenous, intramuscular, intraarteriole, intradermal, subcutaneous, intraperitoneal, intraventricular and intracranial. Other delivery modes include, but are not limited to, the use of liposome formulations, intravenous infusions, etc. Administration also includes direct administration, for example, direct administration to an inflammatory site. Direct administration can be delivered via guidance, such as magnetic resonance imaging (MRI) guided delivery. In an embodiment, administration does not include the administration of any activating agent other than the activating agent listed.
[0044] "Co-administration" means that the compositions described herein are administered at the same time, just before, or just after the administration of one or more additional therapies. The compositions provided herein can be administered alone or can be co-administered to a patient. Co-administration is intended to include the administration of the compositions alone or in combination (more than one composition) simultaneously or sequentially. Therefore, the formulations can also be combined with other active substances when necessary.
[0045] The terms "autologous", "autologous cells" or "autologous transplantation" as used herein in connection with cell transplantation indicate that the donor and recipient of the cells are the same individual. The terms "allogeneic", "allogeneic cells" or "allogeneic transplantation" as used herein in connection with cell transplantation indicate that the donor and recipient of the cells are different individuals of the same species.

Typically, pre-B cells undergo immunoglobulin heavy chain rearrangement to become pre-B precursor B cells, and further undergo immunoglobulin light chain rearrangement to become immature B cells. Immature B cells include T1 and T2 B cells.
[0048] As used herein, "T cells" or "T lymphocytes" are lymphocyte types (white blood cell subtypes) that play an important role in cell-mediated immunity. https: / / en.wikipedia.org / wiki / Cell-mediated_immunity They can be distinguished from other lymphocytes such as B cells and natural killer cells by the presence of T cell receptors on the cell surface. https: / / en.wikipedia.org / wiki / T-cell_receptorhttps: / / en.wikipedia.org / wiki / Cell_surface_receptor T cells include, for example, natural killer T (NKT) cells, cytotoxic T lymphocytes (CTLs), regulatory T (Treg) cells, and T helper cells. In embodiments, T cells are α / β T cells (expressing TCRα / β). In embodiments, T cells are γ / δ T cells (expressing TCRγ / δ). Different types of T cells can be distinguished by using T cell detection agents.
[0049] "Memory T cells" are T cells that have previously encountered and responded to their cognate antigen during a past infection, encounter with cancer, or previous vaccination. Upon encountering their cognate antigen a second time, memory T cells can replicate (divide) to produce an immune response that is faster and stronger than the immune system's first response to the pathogen.

[0060] The term "infection" or "infectious disease" refers to a disease or condition that can be caused by an organism (such as bacteria, viruses, fungi, or any other pathogenic microbial agent). In embodiments, infectious diseases are caused by pathogenic bacteria. Pathogenic bacteria are bacteria that cause disease (e.g., in humans). In embodiments, infectious diseases are bacteria-related diseases (e.g., tuberculosis, which is caused by Mycobacterium tuberculosis). Non-limiting bacteria-related diseases include pneumonia, which can be caused by bacteria such as Streptococcus and Pseudomonas; or foodborne diseases, which can be caused by bacteria such as Shigella, Campylobacter, and Salmonella. Bacteria-related diseases also include tetanus, typhoid, diphtheria, syphilis, and leprosy. In embodiments, the disease is bacterial vaginosis (i.e., bacteria that alter the vaginal microbiota caused by bacterial overgrowth that crowds out Lactobacillus species that maintain a healthy vaginal microbiota) (e.g., yeast infection or Trichomonas vaginalis); bacterial meningitis (i.e., bacterial inflammation of the meninges); bacterial pneumonia (i.e., bacterial infection of the lungs); urinary tract infection; bacterial gastroenteritis; or bacterial skin infection (e.g., impetigo or cellulitis). In embodiments, the infectious disease is Campylobacter jejuni, Enterococcus faecalis, Haemophilus influenzae, Helicobacter pylori, Klebsiella pneumoniae, Legionella pneumophila, Neisseria gonorrhoeae, Neisseria meningitidis, Staphylococcus aureus, Streptococcus pneumoniae, or Vibrio cholerae infection.
[0061] As used herein, the terms "metastasis", "metastatic" and "metastatic cancer" are used interchangeably and refer to the spread of a proliferative disease or condition (e.g., cancer) from one organ or another non-adjacent organ or part of the body. "Metastatic cancer" is also referred to as "stage IV cancer". Cancer occurs at the site of origin, such as the breast, which is called a primary tumor, such as primary breast cancer. Some cancer cells in the primary tumor or site of origin acquire the ability to penetrate and infiltrate the surrounding normal tissues in the local area and / or the ability to penetrate the lymphatic system or the walls of the vascular system that circulates to other parts of the body and tissues through the system. The second clinically detectable tumor formed by the cancer cells of the primary tumor is called a metastatic tumor or secondary tumor. When cancer cells metastasize, it is presumed that the metastatic tumor and its cells are similar to the cells of the original tumor. Therefore, if lung cancer metastasizes to the breast, the secondary tumor at the breast site is composed of abnormal lung cells rather than abnormal breast cells. Secondary tumors in the breast refer to metastatic lung cancer. Therefore, the phrase metastatic cancer refers to a disease in which a subject suffers from or has suffered from a primary tumor and suffers from one or more secondary tumors. The phrase non-metastatic cancer or a subject with non-metastatic cancer refers to a disease in which a subject has a primary tumor but does not have one or more secondary tumors. For example, metastatic lung cancer refers to a disease in a subject with a primary lung tumor or a history of a primary lung tumor and one or more secondary tumors at a second location or locations (e.g., in the breast).
[0062] The term "cutaneous metastasis" or "skin metastasis" refers to secondary malignant cell growth in the skin, where the malignant cells originate from the primary cancer site (e.g., breast). In cutaneous metastasis, cancer cells from the primary cancer site can migrate to the skin, where they divide and cause lesions. Cutaneous metastasis can be caused by the migration of cancer cells from a breast cancer tumor to the skin.
[0063] The term "visceral metastasis" refers to secondary malignant cell growth in an internal organ (e.g., heart, lung, liver, pancreas, intestine) or body cavity (e.g., pleura, peritoneum), wherein the malignant cells originate from a primary cancer site (e.g., head and neck, liver, breast). In visceral metastasis, cancer cells from the primary cancer site can migrate to internal organs, where they divide and cause lesions. Visceral metastasis can be caused by the migration of cancer cells from liver cancer tumors or head and neck tumors to internal organs. As used herein, the term "tumor" or "tumor cell" refers to any type of tumor, including solid tumors or non-solid tumors, diffuse tumors, metastatic or disseminated tumors, or tumor cells from any form of tumor.
[0064] The term "fibrosis" refers to any process of pathological wound healing or fibrous connective tissue development in response to damage or injury. Types of fibrosis include, but are not limited to, pulmonary fibrosis (replacement fibrosis, focal fibrosis, diffuse lung parenchymal disease, cystic fibrosis, fibrothorax, idiopathic pulmonary fibrosis, and radiation-induced lung injury), liver fibrosis (bridging fibrosis, cirrhosis, senescence of hepatic stellate cells), renal fibrosis (CYR61-induced cell senescence), glial scars, cardiac fibrosis (interstitial fibrosis, replacement fibrosis, and myocardial fibrosis), arteriosclerosis, athrofibrosis, chronic kidney disease, Crohn's disease, Dupuytren's contracture, keloids, mediastinal fibrosis, myelofibrosis, Peyronie's disease, nephrogenic systemic fibrosis, progressive massive fibrosis, retroperitoneal fibrosis, scleroderma / systemic sclerosis, and adhesive capsulitis.
[0065] The term "fibroblast" refers to a cell type that secretes extracellular matrix (ECM) components including, but not limited to, collagen, glycosaminoglycans, reticular fibers, elastic fibers, and ground substance.
[0066] The term "vaccine" as used herein refers to any type of biological preparation that contributes to or induces an active immune response to a specific disease or pathogen. Such biological preparations may include, but are not limited to, antigens derived from pathogenic agents or portions of antigens derived from pathogenic agents. Such biological preparations may also be in the form of live attenuated preparations, including live, or weakened or modified pathogenic agents or pathogens; or in the form of inactivated or killed pathogenic agents or pathogens. Alternative forms of such biological preparations also include, but are not limited to, subunits, toxoids, conjugates, DNA, and recombinant vectors, or any suitable form that may be developed in the future or may be used to induce an active immune response thereto.
[0067] It should be noted that in some embodiments, although the term "vaccine" is used herein, the vaccine need not provide significant immunity against smallpox (or any other pathogen), as long as it is effective against the diseases described herein. For example, a vaccine can be any immunogenic or infectious composition that treats a disease. In some cases, the term is used to identify certain materials or compositions, not necessarily the ability of the material or composition to provide immunity, such as against smallpox. The virus can be from any strain, including, for example, one or more listed below and elsewhere herein, including those strains that are not part of an approved or contemplated vaccine.
[0068] As used herein, "virus" refers to any one of a large group of entities called viruses. Viruses generally contain a protein shell surrounding the RNA or DNA core of genetic material, but do not contain a semipermeable membrane, and can only grow and proliferate in living cells. The viruses used in the methods provided herein include, but are not limited to, poxviruses, adenoviruses, herpes simplex viruses, Newcastle disease viruses, vesicular stomatitis viruses, mumps viruses, influenza viruses, measles viruses, reoviruses, human immunodeficiency viruses (HIV), hantaviruses, myxoma viruses, cytomegaloviruses (CMV), slow viruses, and any plant or insect viruses.
[0069] As used herein, "heterologous nucleic acid" refers to a nucleic acid, i.e., DNA or RNA, that has been introduced into a virus or cell (or an ancestor of a cell). Such heterologous nucleic acids may comprise the sequence of a gene and operable regulatory elements. For example, a heterologous nucleic acid may comprise a selectable marker gene, a suicide gene, or a gene that expresses a useful protein product that is not endogenously expressed or is endogenously expressed at a low level.
[0070] As used herein, the term "concurrently" referring to the administration of oncolytic viruses and cells refers to administration within 48 hours of each other. In some embodiments, the oncolytic viruses and cells are administered within 36 hours of each other, within 24 hours of each other, within 12 hours of each other, within 10 hours of each other, within 8 hours of each other, within 6 hours of each other, within 4 hours of each other, within two hours of each other, and within 1 hour of each other.
[0071] The terms "autologous", "autologous cells" or "autologous transplantation" as used herein in connection with cell transplantation indicate that the donor and recipient of the cells are the same individual. The terms "allogeneic", "allogeneic cells" or "allogeneic transplantation" as used herein in connection with cell transplantation indicate that the donor and recipient of the cells are different individuals of the same species.
[0072] "Pharmaceutically acceptable excipients" and "pharmaceutically acceptable carriers" refer to substances that facilitate administration of active agents to subjects and / or facilitate absorption by subjects, and the substances can be included in the compositions of the present disclosure without causing significant adverse toxicological effects to patients. Non-limiting examples of pharmaceutically acceptable excipients include water, NaCl, physiological saline solutions, lactated Ringer's solutions, normal sucrose, normal glucose, binders, fillers, disintegrants, lubricants, coatings, sweeteners, flavors, salt solutions (such as Ringer's solutions), alcohols, oils, gelatin, carbohydrates such as lactose, straight-chain starch or starch, fatty acid esters, hydroxymethylcellulose, polyvinylpyrrolidine, and pigments, etc. Such preparations can be sterilized and, if necessary, can be mixed with adjuvants (such as lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for affecting osmotic pressure, buffers, coloring substances and / or aromatic substances, etc.), which do not react harmfully with the compounds of the present disclosure. Those skilled in the art will recognize that other pharmaceutical excipients can also be used in the present disclosure.
[0073] II. Oncolytic viruses
[0074] Oncolytic viruses are viruses that target cancer cells. Oncolytic viruses can be genetically engineered to selectively replicate in cancer cells and lyse cancer cells while avoiding healthy cells. Oncolytic viruses destroy cancer cells by 1) directly infecting cancer cells and lysing them, or 2) recruiting and directing a renewed host immune response to cancer cells.
[0075] The potential of oncolytic viruses as cancer treatments was first discovered after patients with myeloid leukemia were infected with influenza and entered spontaneous remission. Viruses from many categories have been genetically engineered to be oncolytic, including but not limited to: adenovirus, herpes virus, measles virus, coxsackie virus, polio virus, reovirus, pox virus, vaccinia virus, vesicular stomatitis virus, Seneca virus, RIGVIR, Semliki Forest virus, Maraba virus and Newcastle disease virus. Viral components are targets for genetic engineering and include: addition of tumor-specific promoters, viral gene knockout, viral capsid modification and expression of immune system activators (including antibodies, cytokines and co-stimulatory molecules).
[0076] Variola virus is the cause of smallpox. Unlike variola virus, vaccinia virus does not usually cause systemic disease in immunocompetent individuals, so it has been used as a live vaccine to immunize against smallpox. Due to successful vaccination against vaccinia virus worldwide, smallpox has been eradicated as a natural disease. Except for people at higher risk of poxvirus infection (e.g., laboratory workers), routine smallpox vaccination has been stopped for many years. Although routine childhood immunization against smallpox was stopped in the United States in 1972, the use of smallpox vaccine is generally considered safe for pediatric use.
[0077] Attenuated strains derived from pathogenic viruses can be used to produce live vaccines. Non-limiting examples of virus strains that have been used as smallpox vaccines include, but are not limited to, Listeria (also known as Elstree), New York City Health Department strain ("NYCBH strain"), Dalian strain, Ikeda strain, LC16M8 strain, Western Reserve (WR) strain, Copenhagen strain, Tashkent strain, Tiantan strain, Wyeth strain, IHD-J and IHD-W strains, Brighton strain, Ankara strain, MVA strain, Dalian type I strain, LIPV, LC16MO, LIVP, WR 65-16, EM63, and Connaught strain. In some embodiments, the smallpox vaccine as disclosed herein is an attenuated New York City Health Department (NYCBOH) strain of vaccinia virus. In some embodiments, the NYCBOH strain of vaccinia virus can be ATCC VR-118 or CJ-MVB-SPX.

[0135] Example
[0136] Example 1: Preparation of patient-derived CAR T cells
[0137] As previously reported (Quintarelli et al., Oncoimmunology. 2018;7(6):e1433518, incorporated herein by reference in its entirety), patient-derived cells were expanded and cultured in the presence of IL7 and IL15; the same procedure is used in ongoing Phase I / II clinical studies (NCT03373097 and NCT03373071).
[0138] Briefly, peripheral blood mononuclear cells (PBMCs) were isolated from buffy coats obtained from healthy donors using lymphocyte separation medium. T lymphocytes were activated with immobilized OKT3 (1 μg / ml) and anti-CD28 (1 μg / ml) monoclonal antibodies (mAbs) in the presence of recombinant human interleukin-2 (IL2, 100 U / ml), or with a combination of recombinant human interleukin-7 (IL7, 10 ng / ml) and 15 (IL15, 5 ng / ml). On day 3, activated T cells were transduced using supernatants and the above-mentioned specific cytokines in plates pre-coated with recombinant human RetroNectin. On day 5 after transduction, T cells were expanded in a medium containing 45% RPMI1640 and 45% Click medium (Sigma-Aldrich, Co.; USA), supplemented with 10% FBS and 2 mM Glutamax, and supplemented twice a week.
[0139] Example 2: Vaccinia virus infection of CAR T cells
[0140] exist Figure 1-9B T cells used in the studies shown were infected in the presence of culture medium in each experiment. Exemplary infections included 2.5 x 10 6 VV PFU (MOI 5) infected about 5x10 5 Cells / ml were maintained for 2 to 3 days. Infected cells were washed three times before any co-culture experiments.
[0141] Vaccinia virus can infect polyclonal activated T cells and chimeric antigen receptor (CAR) T cells. In addition, vaccinia virus can replicate inside T cells to produce new viral progeny. Figure 1 Fluorescence micrographs of CAR T cells before infection with vaccinia virus (LIVP1.1.1) (left panel) and 48 hours (h) after infection (right panel) are shown.
[0142] Example 3: Cellular assay of CAR T cells infected with vaccinia virus
[0143] Figure 2 Two graphs are shown indicating that CAR T cells are more susceptible to vaccinia virus infection than non-transduced (NT) T cells. The left graph shows the total virus-infected area (μm) over time (hours) for three groups of CAR cells versus NT cells generated from three patients. 2 / image). The right panel shows the total viral infection area (μm) at the end of the time course (65 hours) for each condition (patients 1, 2, and 3 CART and NT samples). 2 / image).
[0144] Figure 3.Shows that for two vaccinia virus strains, previously infected CAR T / NT cells spontaneously release low levels of virus over 96 hours. In the upper two panels, the Listeria strain (variants TurboFP635 and ig-GFP) was used, and in the lower panel, the Copenhagen strain (TurboFP635 variant) was used. In each case, a total of ~7x10 5 The total plaque forming units (PFU) were counted and plotted at 24, 48, 72, and 96 hours.
[0145] Figure 4. Shows that vaccinia virus released by previously infected T cells can infect tumor cells in vitro. It was also found that vaccinia-infected T cells remain functional and that vaccinia virus is released from infected T cells only after the CAR receptor or exogenous T cell receptor engages the target tumor cell. Vaccinia-infected tumor cells are lysed and new vaccinia virus particles are released.
[0146] Figure 5 .Show that CAR T cells infected with vaccinia virus eradicate more SH-SY5Y neuroblastoma cells than CAR T cells alone. SH-SY5Y cells were co-cultured with CAR T cells (top row) or CART cells previously infected with vaccinia virus (bottom row) at a 2:1 ratio. Compared with tumor cells co-cultured with CAR T cells alone, tumor cell eradication was significantly enhanced during 75 hours in tumor cells co-cultured with CAR T cells infected with vaccinia virus. These data represent in vitro co-cultures that are closer to in vivo conditions, with more tumor cells than T cells in the co-cultures.
[0147] Figure 6 . A graph showing the total green object area (live cells) versus time (hours) indicates the amount of intact tumor cells in cultures alone, +vaccinia virus (0.01 MOI), +CAR T cells (2:1 co-culture), or containing vaccinia virus-infected CAR T cells.
[0148] Figure 7 .Shows the number of vaccinia-infected T cells under the indicated conditions. The two figures on the left represent FACS analysis data (%) of polyclonal activated T cells infected with vaccinia, and the two figures on the right show FACS analysis of CAR expression regulation after vaccinia virus infection. The right figure shows CAR expression under each condition as % CAR-positive cells. Compared with non-genetically modified T cells, vaccinia virus infection is more homogeneous in CAR-redirected T cells, and vaccinia infection has no negative impact on the level of CAR T cell expression. No infection-NT: uninfected T cells; No infection-CAR: uninfected CAR T cells; Infection-NT: vaccinia-infected T cells; Infection-CAR: vaccinia-infected CAR T cells.
[0149] Figure 8 .The left figure shows vaccinia virus-infected T cells, NK cells, and NK-T cells. FACS analysis of cell subsets present in patient-derived CAR gene-modified T cells. The left figure shows the percentage of T populations, NK populations, and NK-T populations in non-genetically modified (NT-untransduced) T cells and genetically modified CARs after vaccinia infection. On the right, FACS analysis of CD8 and CD4 compartments in CD3+ populations with or without vaccinia infection in NT and CAR+ patient-derived lymphocytes. CAR detection: anti-CAR idiotype. T cell populations include: CD45 / CD3, NK-T: CD45 / CD3 / CD56, NK: CD45 / CD56+ / CD3-. The right figure shows CD4 and CD8 subsets of vaccinia virus-infected T cells. In this example, the percentage of infection in CD8 cells is greater than the percentage of infection in CD4 cells. The right panel shows from left to right the % positive cells compared to the following cells: VV+: only VV positive cells, CAR+: only CAR positive cells, + / +: cells positive for VV and CAR, - / -: cells double negative for VV and CAR.
[0150] Fig. 9A Vaccinia infection induces T cell maturation primarily in the CD8 compartment, with a small number of naive cells and a large number of effector cells. Fig. 9B Vaccinia infection induces T-cell maturation predominantly in the CD8 compartment, with a small number of naive cells and a large number of effector cells. Fig. 9A and Fig. 9B It was shown that in the CD8 compartment, after VV infection, the amounts of naive and memory T cell subsets were reduced compared to non-vaccinia infected cells.
[0151] Example 4: Administration of vaccinia virus-infected CAR T cells
[0152] T cells are removed from the patient's blood by apheresis or leukapheresis. The T cells are optionally genetically engineered to express a chimeric antigen receptor of interest. The T cells can be expanded in vitro.
[0153] T cells are infected with vaccinia virus at an MOI of about 2. The infected T cells are administered to the patient via intravenous injection.
