[Modes for carrying out the invention]

[0080] The inventors have developed a method to eliminate hematological malignancies without causing GVHD and to reverse allogeneic rejection. We developed a CAR-modified virus-specific T cell (CAR-VST) approach to avoid it. .

[0081] This disclosure is intended to protect allogeneic tissues, including pre-made cell therapies, from graft rejection, or GVH. To treat D, we provide strategies to eliminate alloreactive T cells.

[0082] CD30 has been identified as a marker for alloreactive T cells, and therefore, the present invention These individuals express a chimeric antigen receptor (CAR) for CD30 (CD30.CAR). These were targeted by manipulating T cells used for sea urchin therapy. CD30.CAR expression V ST is used to reduce the alloreactive immune response in recipients. It can be used in methods of providing medical treatment.

[0083] Administering allogeneic T cells to HLA mismatch recipients means that some of the T cells are essential Because it exhibits alloreactivity, it carries the risk of alloreactive immune responses such as GVHD. Akira et al. used virus-specific cells as platform cells for expressing CD30.CAR. T cells (VSTs) were used, but this rarely causes GVHD in allogeneic recipients. This is because it has been shown to cause this, and this is probably due to their restricted TCR This is the result of the repertoire. In particular, Epstein-Barr virus-specific T cells (EBVS) T) has been administered to over 300 allogeneic recipients without evidence of GVHD.

[0084] Furthermore, CD30.CAR-expressing VST itself exhibits alloreactivity in recipients. Protected from cellular rejection, and therefore, ready-made for the treatment of, for example, CD30+ cancer It can be used directly as a therapy.

[0085] Therefore, CD30.CAR VST (i) induces allogeneic reactions in allogeneic hosts. (ii) Eliminate responsive T cells and eliminate CD30-positive cancer without causing GVHD. It sustains for a sufficient amount of time with the necessary activity.

[0086] CD30.CAR expression VST is also specific to other target antigens besides CD30, for example. By manipulating the expression of specific CARs, further target antigens can be targeted. Such cells can be manipulated to kill cells that express the target antigen. It is possible to eliminate CD30-expressing allogeneic T cells, thus eliminating the expression of the relevant target antigen. It is useful as a ready-made treatment method for cancer and other diseases.

[0103] EBNA1 is multifunctional and influences genetics through positive and negative regulation of the viral promoter. It plays a role in gene regulation, extrachromosomal replication, and maintenance of the EBV episomal genome. ellman et al., J Gen Virol. (2009);90(Pt9):2251- 2259). EBNA2 is involved in the regulation of latent viral transcription in cells infected with EBV. Contributes to immortalization (Kempkes and Ling, Curr Top Micro biol Immunol. (2015) 391:35-59). EBNA-LP is naturally occurring. It is necessary for the transformation of B cells and recruits transcription factors for viral replication (Szymu la et al., PLoS Pathog. (2018);14(2):e1006890). E BNA3A, 3B, and 3C interact with RBPJ to affect gene expression and infection cells. It contributes to the survival and proliferation of cells (Wang et al., J Virol. (2016) 90(6): 2906-2919). LMP1 regulates the expression of genes involved in B cell activation. Chang et al., J. Biomed. Sci. (2003) 10(5):490-504 ). LMP2A and LMP2B positively mimic activated B cell receptors. Inhibits normal B cell signaling (Portis and Longnecker, O ncogene (2004) 23(53):8619-8628). EBER is host cell It forms protein-ribonucleoprotein complexes and plays a role in cell transformation. This has been proposed.

[0104] The latent cycle progresses according to one of the latent programs I-III in B cells. It can progress to stages III, II, and I. It infects naive B cells in a resting state. Then, EBV enters latent program III. The expression of the latent phase III gene activates B cells. Upon sexualization, B cells become proliferative blasts. Subsequently, EBV is typically expressed in memory B cells. By restricting to a subset of genes that cause blast differentiation, during latent phase II... It progresses. Further restriction of gene expression causes EBV to enter latent phase I. EBNA1 expression This allows EBV to replicate when memory B cells divide. In epithelial cells, latency Only Phase II occurs.

[0105] In primary infection, EBV replicates in oral and pharyngeal epithelial cells and undergoes a latent period in B lymphocytes. III, II, and I infections are established. Latent EBV infection in B lymphocytes indicates viral survival. This is necessary for subsequent replication in epithelial cells and for the release of infectious viruses into saliva. EBV infection of B lymphocytes during latent phases III and II, latent phase II infection of oral epithelial cells, and In NK cell or T cell latent phase II infection, the presence of a uniform EBV genome and gene expression are due to the presence of a uniform EBV genome. It can lead to malignant tumors characterized in that way.

[0106] Latent EBV in B cells can be reactivated and switched to lytic replication. The lytic cycle leads to the production of infectious virions and can occur in B cells and epithelial cells. For example, Kenney, Arvin et al., Human Herpesviruses: B iology,Therapy and Immunoprophylaxis;Cam Outlined in Chapter 25 of bridge University Press (2007) Therefore, this entirety is incorporated herein by reference.

[0107] Lysolytic replication requires the EBV genome to be linear. The potential EBV genome is It is a bisome and therefore must be linearized for soluble reactivation. In cells, lytic replication usually occurs only after reactivation from the incubation period.

[0108] Immediate lytic gene products such as BZFL1 and BRLF1 are transactivators. It acts in a way that enhances the expression of those genes themselves, as well as the expression of late-stage lytic cycle genes.

[0109] The initial lytic gene product is a catalytic component of viral replication (e.g., EBV DNA polymerase). BALF5; DNA polymerase processing factor BMRF1, DNA binding protein Calcium BALF2, helicase BBLF4, primase BSLF1, and primase-related (Trivalent protein BBLF2 / 3) and deoxyribonucleotide metabolism (e.g., thymidine kinase) It plays a role in the ze BXLF1 and dUTPase BORF2. Other early lysis genes The product acts on transcription factors (e.g., BMRF1, BRRF1) to improve RNA stability and process It plays a role in Sing (e.g., BMLF1) or immune evasion (e.g., Apot) It is involved in BHRF1, which inhibits systolic function.

[0110] Late-lysed gene products are traditionally classified as those expressed after the initiation of viral replication. These are generally structural components of virions, such as nucleocapsid proteins. Furthermore, glycoproteins that mediate EBV binding and fusion (e.g., gp350 / 220, gp It encodes 85, gp42, gp25). Other late-lysing gene products are involved in immune evasion. It has a role; BCLF1 encodes a viral homolog of IL-10, and BALF1, It encodes a protein homologous to the anti-apoptotic protein Bcl2.

[0118] Chimeric antigen receptor This disclosure relates to virus-specific immune cells containing / expressing chimeric antigen receptors (CARs). do.

[0119] Chimeric antigen receptors (CARs) provide both antigen-binding and T-cell activation functions. It is a recombinant receptor molecule. The CAR structure and engineering are described in their entirety by reference, for example, in this specification. It is incorporated into Dotti et al., Immunol Rev (2014) 257(1) as outlined. It is being done.

[0120] CARs are antigen-binding domains linked to the signaling domain via a transmembrane domain. It includes. Any hinge or spacer domain contains an antigen-binding domain and a transmembrane domain. It can provide separation between cells and can act as a flexible linker. When expressed by [unclear], the antigen-binding domain is provided to the extracellular space, and the signaling domain Insulin is located inside cells.

[0121] The antigen-binding domain of a CAR mediates the binding of the CAR to a specific target antigen. The antigen-binding domain of a CAR is based on the antigen-binding region of an antibody that is specific to the target antigen. For example, the antigen-binding domain of a CAR is the phase of an antibody that specifically binds to a target antigen. It may contain the amino acid sequence of the complementarity-determining region (CDR). The antigen-binding domain of the CAR is the target It contains, or is not, the light chain and heavy chain variable region amino acid sequence of an antibody that specifically binds to an antigen. It can be. The antigen-binding domain contains the amino acid sequences of the variable regions of the antibody's light and heavy chains. It may be provided as a single-chain variable fragment (scFv). The antigen-binding domain of the CAR is Ligand: Targets antigens based on other proteins such as receptor binding and protein-protein interactions. For example, IL-13Rα2 target CARs can be antigen-binding based on IL-13. Developed using domains (e.g., Kahlon et al. 2004 Cancer) See Res 64(24):9160-9166.

[0122] The transmembrane domain is provided between the antigen-binding domain and the CAR signaling domain. The transmembrane domain fixes the CAR to the cell membrane of cells expressing the CAR, and the antigen-binding domain The CAR provides the signaling domain to the extracellular space and the signaling domain to the cell. The nucleotides originate from the transmembrane domain sequences of cell membrane-bound proteins (e.g., CD28, CD8, etc.). obtain.

[0123] Throughout this specification, the reference polypeptide / domain / amino acid sequence "derived" The cytoplasm, domain, and amino acid sequence are the reference polypeptide / domain / amino acid sequence. At least 60%, preferably 70%, 75%, 80%, 85%, 90% of the no-acid sequence. %, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 1 It has 00% amino acid sequence identity. Reference polypeptide / domain / amino acid sequence " The resulting polypeptide, domain, and amino acid sequence are preferably a reference polypeptide / domain.

As shown in 26, 60%, preferably 70%, relative to the intracellular domain of CD28. 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, It contains amino acid sequences having 97%, 98%, 99%, or 100% amino acid sequence identity. Furthermore, the amino acid sequence derived from the intracellular domain of CD28 is preferably sequence ID. The functional properties of amino acid sequence number 26, namely, activation of CD28-mediated signaling. To retain the ability to do so.

[0125] The amino acid sequence of a given polypeptide or its domain is from a database known to those skilled in the art. It can be searched from or determined from the retrieved nucleic acid sequence. This includes GenBank, EMBL, and UniProt.

[0126] The signaling domain contains amino acid sequences necessary for activating immune cell function. CAR The signaling domain is responsible for the phosphorylation and activation of CAR-expressing cells by the immune receptor tyrosine. The intracellular domain of CD3-ζ provides the synbase activation motif (ITAM). May contain mino acid sequences. Signaling domains containing sequences of other ITAM-containing proteins. For example, the domain containing the ITAM-containing region of FcγRI is also used in CAR. (Haynes et al., 2001 J Immunol 166(1):182-187) ). CARs containing a signal transduction domain derived from the intracellular domain of CD3-ζ are the first It is often referred to as a generational car.

[0127] The signaling domains of CARs typically enhance immune cell activation and effector functions. Co-stimulatory proteins (e.g., CD2) provide the necessary co-stimulatory signals for strengthening. It also includes signaling domains (8, 4-1BB, etc.). Signals containing additional co-stimulatory sequences. CARs that have a transmission domain are often called second-generation CARs. In this context, CARs are engineered to provide co-stimulation of different intracellular signaling pathways. For example, CD28 co-stimulation is mediated by phosphatidylinositol 3-kinase (P13K). While it preferentially activates pathways, 4-1BB co-stimulation is associated with TNF receptor-related factor (TRAF). It induces signal transduction mediated by pter proteins. Therefore, CAR signal transduction The domain is a co-stimulatory sequence sometimes derived from the signaling domains of one or more co-stimulatory molecules. It contains a signaling domain with multiple co-stimulatory sequences, a third-generation CAR. It is often called CAR.

[0128] Any hinge or spacer region separates the antigen-binding domain from the transmembrane domain. can be provided and can act as a flexible linker. Such regions are for example, can be, or can include, a flexible domain that can be derived from the CH1-CH2 hinge region of IgG and allows the binding moieties to be oriented in different directions.

[0129] By engineering immune cells ( typically not only T cells, but also other immune cells such as NK cells) to express a CAR specific for a particular target antigen, the immune cells can be directed to kill cells expressing the target antigen. Binding of a CAR-expressing T cell (CAR-T cell) to the target antigen to which it is specific induces intracellular signaling and, as a result, activation of the T cell. The activated CAR-T cells divide, are stimulated to produce factors, and result in the death of cells expressing the target antigen.

In some embodiments, the co-stimulatory sequence is the intracellular domain of the co-stimulatory protein. It is either an amino acid sequence or an amino acid sequence derived therefrom.

[0187] When a CAR binds to a target antigen, the co-stimulating sequence undergoes ligation by an alloligon. During this process, the type of CAR provided by the co-stimulating protein from which the co-stimulating sequence originates is generated. It provides simultaneous stimulation to the cells present. For example, a SIG containing a co-stimulatory sequence derived from CD28. In the case of CARs containing a signaling domain, binding to the target antigen is via CD80 and / or CD8 Signaling in cells expressing a type of CAR induced by the binding of 6 to CD28 It induces transmission. Therefore, the co-stimulatory sequence is the co-stimulatory protein from which the co-stimulatory sequence originates. It can deliver co-stimulatory signals.

[0190] A given amino acid sequence initiates signal transduction mediated by a given co-stimulatory protein. Whether this is possible depends, for example, on the signal transmission mediated by co-stimulatory proteins. Correlation between proteins (for example, signal transduction whose expression / activity is mediated by a co-stimulatory protein) By analyzing the expression / activity of factors that are upregulated or downregulated as a result, adjustments can be made. It can be investigated.

[0191] Co-stimulatory proteins, through several transduction pathways, contribute to cell proliferation and effector functions. and upregulates the expression of genes that promote survival. For example, CD28 and ICOS are phosphatidyl Signal transduction is mediated via phatidylinositol 3-kinase (PI3K) and AKT, N Cell proliferation, effector function and It upregulates the expression of genes that promote survival. CD28 also mediated through RAS to CDC AP1 / 2 is activated via 42 / RAC1 and ERK1 / 2, and ICOS is C-MAF Activate 4-1BB, OX40, and CD27 via the MAPK path It recruits TNF receptor-related factors (TRAFs) and signaling pathways via PI3K.

(2014) 37(4):193-203, which is hereby incorporated by reference in its entirety.

[0237] Advantageously, cultures of cells according to the invention can be maintained at 37 °C in a humidified atmosphere containing 5% CO2. The cells of the cell culture can be established and / or maintained at any suitable density, as can be readily determined by those of skill in the art. For example, the culture can be established at an initial density of about 0 .5×10 cells to about 5×10 6 cells (e.g., about 1×10 6 cells / ml). 6

[0238] The culture can be performed, for example, in wells such as cell culture plates, cell culture flasks, bioreactors, or in any container suitable for the volume of the culture. In some embodiments, the cells [[ID=*]] Cells are bioreactors, for example, Somerville and Dudley, Onc.

In some embodiments, cells are cultured in a GRex cell culture vessel, for example, a GRex flask or It is cultured in a GRex 100 bioreactor.

[0239] This method generally involves antigen-presenting cells (A) that present viral antigen peptide:MHC complexes. In the presence of PCs, a population of immune cells (e.g., immune cells) containing cells with antigen-specific receptors This process causes the activation and proliferation of a heterogeneous population of cells, such as peripheral blood mononuclear cells (PBMCs). This includes culturing under conditions that provide appropriate co-stimulation and signal amplification. APC is They may be infected with a virus that codes for viral antigens / peptides (multiple), or they may be infected with a virus that codes for viral antigens / peptides. It may contain / express, and may present a viral antigen peptide in the context of an MHC molecule. Good. The stimulation triggers T cell activation, which promotes cell division (proliferation) and specifically targets viral antigens. This results in the generation and / or expansion of heterogeneous T cell populations. The process of T cell activation is as described by those skilled in the art. This is well known, for example, Immunobiology, 5th Edn. Janeway CA Jr, Travers P, Walport M et al., New York: Garl and Science (2001), Chapter 8 (the entire text is referenced in this specification). See (which is incorporated into the book).

[0240] The cell population obtained after stimulation showed a greater number of virus-specific T cells compared to the pre-stimulation population. It is concentrated in relation to (i.e., virus-specific T cells increase in the population after stimulation) (They exist at a certain frequency). In this way, virus-specific populations of T cells are different specific They are generated / proliferated from heterogeneous populations of sexually active T cells. It can be generated from a single T cell by stimulation and subsequent cell division. Virus-specific The existing population of T cells is stimulated by the virus-specific T cell population and as a result It can be expanded by cell division.

[0241] The aspects and embodiments of this disclosure relate particularly to EBV-specific immune cells. Therefore, In some embodiments, the virus may be EBV, and the viral antigen may be EBV antigen. Methods for generating / expanding populations of EBV-specific immune cells include, for example, WO2013 / 088114A1,Lapteva and Vera,Stem Cells Int (2011):434392, Straathof et al., Blood (2005) 105 (5):1898-1904, WO2017 / 202478A1, WO2018 / 052 947A1 and WO2020 / 214479A1 (all of these are by reference in their entirety) (This is incorporated herein).

[0242] This method targets the T cell receptor (TCR) specific to the EBV antigen peptide:MHC complex. The T cells containing the APC present an EBV antigen peptide:MHC complex that is specific to the TCR. The step includes being stimulated by APC, which encodes the EBV antigen / peptide, or Infection with a virus containing / expressing it, and the EBV antigen peptide in association with MHC molecules. This indicates that stimulation triggers T cell activation, promoting cell division (proliferation) and specifically targeting the EBV antigen. This leads to the generation and / or expansion of heterogeneous T cell populations.

In other words, in some embodiments, cancer is caused by a viral infection. Cancers that are caused or worsened by viral infection, cancers in which viral infection is a risk factor, and / or Cancers in which infection by a virus is positively associated with the onset, development, progression, severity, or metastasis of the cancer.

[0423] EBV infection has been reviewed, for example, by Jha et al. in Front Microbiol. It is involved in several types of cancer. See (2016)7:1602.

[0424] In some embodiments, the cancer being treated / prevented is EBV-related cancer. In terms of treatment, cancer is cancer caused or exacerbated by EBV infection. Cancer in which infection by EBV is a risk factor, and / or cancer onset, onset, and progression. Cancers that are positively associated with severity or metastasis. Cancers can be characterized by EBV infection, for example. For example, cancer can contain cells infected with EBV. Such cancers are called EBV-positive cancers. obtain.

[0425] EBV-related cancers that can be treated / prevented in accordance with this disclosure include B-cell cancers such as Burkitt lymphoma. Related cancers, post-transplant lymphoproliferative disorders (PTLD), central nervous system lymphoma (CNS lymphoma) ), Hodgkin lymphoma, non-Hodgkin lymphoma, and EBV-associated lymphoma associated with immunodeficiency ( For example, this includes: EBV-positive lymphoma associated with X-linked lymphoproliferative disorder, HI EBV-positive lymphoma associated with V infection / AIDS, oral hair follicle leukoplakia, and nasopharyngeal carcinoma (NPC) ), including gastric cancer (GC).

[0426] In some embodiments, cancer is lymphoma (e.g., EBV-positive lymphoma), head and neck cancer. Squamous cell carcinoma (HNSCC; e.g., EBV-positive HNSCC), nasopharyngeal carcinoma (NPC; e.g., The cancer is selected from EBV-positive NPCs and gastric cancer (GC; e.g., EBV-positive GCs).

[0427] In some embodiments, the cancer is a cancer in which the target antigen of the CAR is pathologically involved. In other words, in some embodiments, cancer is caused by the expression of a target antigen or Cancers that worsen, cancers in which the expression of a target antigen is a risk factor, and / or cancers in which the expression of a target antigen is a risk factor. Cancer is a cancer that is positively associated with the development, progression, severity, or metastasis of a target antigen. Cancer may be characterized, for example, by including cells that express a target antigen. It can be said that it is positive for the target antigen.

[0428] Cancers that are "positive" for a target antigen are cells that express the target antigen (for example, on the cell surface). It may be a cancer containing cells. Cancers that are "positive" for the target antigen may overexpress the target antigen. Overexpression of the target antigen is higher than the expression level in equivalent non-cancerous cells / non-tumor tissues. This can be determined by detecting the gene or protein expression levels of the target antigen.

[0429] In some embodiments, the target antigen is a cancer cell antigen as described herein. In this embodiment, the target antigen is CD30.

[0430] In some embodiments, the cancer is a cancer in which CD30 is pathologically involved. That is, In some embodiments, cancer is a cancer in which CD30 expression is caused or exacerbated, C Cancers in which D30 expression is a risk factor, and / or cancers in which CD30 expression is associated with the onset, development, and progression of cancer. Cancers that are positively associated with severity or metastasis. Cancers can be characterized by CD30 expression, for example. For example, cancer may contain cells that express CD30. Such cancers are called CD30-positive cancers. It is possible.

[0431] CD30-positive cancer is characterized by cells that express CD30 (for example, the CD30 protein on the cell surface). It may be a cancer that includes cells expressing CD30. CD30-positive cancers may overexpress CD30. CD30 overexpression is higher than the expression levels in equivalent non-cancerous cells / non-tumor tissues. This can be determined by detecting the expression levels of 30 genes or proteins.

[0432] CD30-positive cancers are, for example, described by van der Weyden et al., Blood Can cer Journal (2017) 7:e603 and Muta and Podack It is described in Immunol Res (2013), 57(1-3):151-8. Both of these are incorporated herein in their entirety by reference. CD30 is activated On small subsets of T and B lymphocytes, as well as classical Hodgkin lymphoma and anaplastic large cells. It is expressed by various lymphoid neoplasms, including follicular lymphoma. Variable expression of CD30 is also Peripheral T-cell lymphoma, other unspecified (PTCL-NOS), adult T-cell leukemia / liary Lymphoma, cutaneous T-cell lymphoma (CTCL), extranodal NK-T cell lymphoma, various B-cell non- Hodgkin lymphoma (diffuse large B-cell lymphoma, especially EBV-positive diffuse large B-cell lymphoma) CD3 Expression of 0 is also observed in several non-hematopoietic malignancies, including germ cell tumors and testicular germinal carcinomas. This has also been observed.

[0433] Transmembrane glycoprotein CD30 is a member of the tumor necrosis factor receptor superfamily. Yes (Falini et al., Blood (1995) 85(1):1-14). TNF / TN Members of the TNF-R (F receptor) superfamily modulate the immune response at multiple levels. CD30 plays a role in regulating the function or proliferation of normal lymphoid cells. It was originally described as an antigen recognized by the monoclonal antibody Ki-1, and this is (Muta and Po) duck, Immunol Res (2013)57:151-158). CD30 antigen Expression is used to identify ALCL and Reed-Sternberg cells in Hodgkin's disease. It is used (Falini et al., Blood (1995) 85(1):1-14). Therefore, due to its widespread expression in lymphoma malignant cells, CD30 is used in antibody-based immune responses. It is a potential target for developing both therapeutic and cell therapies. Importantly, CD30 It is typically not expressed on normal tissues under physiological conditions, and therefore, resting, maturing, or pre-maturation. (Younes and Ansell, Semin) Hematol (2016) 53:186-189). Antibodies targeting CD30. Brentuximab vedotin, a substance conjugate, is used for the treatment of CD30-positive HL. Originally approved (Adcetris® US Package Insert 2018) Data from the brentuximab vedotin trial suggests it is a therapeutic target for CD30-positive lymphoma. While I support CD30 as a viable option, I am concerned about the potential harm associated with its use.

[0434] Hodgkin lymphoma (HL) is a rare malignant tumor that involves the lymph nodes and lymphatic system. The incidence of L is bimodal, with the majority of patients diagnosed between the ages of 15 and 30, and those over 55. Another peak follows in adults. In 2019, there were 8,110 new cases in the US (3 in women). 540 people (4,570 men), and 1,000 deaths (4 women) due to this disease. It is estimated that there are 10 cases (590 men) (American Cancer). Society 2019). 20 in the SEER database of the National Cancer Institute, USA. Based on cases from 2012 to 2016, the incidence of HL in pediatric HL patients in the United States is as follows: The ratio is: Age 1-4: 0.1; Age 5-9: 0.3; Age 10-14: 1.3; Age 1 5-19: 3.3 per 100,000 years (SEER Cancer Statistics) [CS Review, 1975-2016]. The World Health Organization (WHO) classification is HL. Two main types: classical Hodgkin lymphoma (cHL) and nodular lymphocyte-predominant Hodgkin lymphoma. It is divided into quinine lymphoma (NLPHL). In Western countries, cHL accounts for 95%, and NLPH L accounts for 5% of all HL (National Comprehensive Canc er Network Guidelines 2019).

[0435] First-line chemotherapy for cHL patients with advanced disease has a 70-75% cure rate. Related to the healing rate (Karantanos et al., Blood Lymphat Cancer) (2017) 7:37-52). Salvage chemotherapy and subsequent autologous stem cell transplantation (ASC). T) is commonly used for patients who have relapsed after initial treatment. Unfortunately, 5 in cHL patients Up to 0% of patients experience disease relapse after ASCT. Overall survival of patients who relapsed after ASCT. The median is approximately 2 years (Alinari Blood (2016) 127:287-2 95). Despite aggressive multi-drug chemotherapy, 10% to 40% of patients still receive rescue chemotherapy. Randomized clinical trials supporting ASCT in non-responders who did not achieve a response to therapy There are no data points. Patients who do not respond to salvage chemotherapy, relapse after ASCT, or this approach For patients who are not candidates for treatment, the prognosis remains critical, and new treatment approaches are urgently needed. (Keudell British Journal of Haemat) ology(2019)184:105-112).

[0436] The majority of the pediatric population (children, adolescents, and young adults) can be cured with currently available treatments, A small number of patients may have refractory or recurrent disease, with acceptable safety with improved efficacy benefits. Novel therapies with a complete sexual profile may be required (Flerlage et al., Blood) (2018)132:376-384;Kelly,Blood(2015) 126: 2452-2458;McClain and Kamdar,in UpToDate 2019;Moskowitz,ASCO Educational Book(20 19)477-486). HL patients treated with high-dose chemotherapy in childhood generally have cardiac problems. , long-term sequelae associated with the treatment of lung, gonad, and endocrine toxicity, as well as secondary malignant neoplasms. To experience (Castellino et al., Blood (2011) 117(6):1806- 1816).

Celiac sclerosis, rheumatoid arthritis, inflammatory bowel disease, type 1 diabetes, juvenile idiopathic arthritis, and celiac disease It has been shown to be associated with risk factors for the development of the disease (Harley et al., Nat G enet. (2018) 50(5):699-707).

[0451] Therefore, in some embodiments, the disease / condition treated / prevented in accordance with this disclosure is Autoimmune diseases, SLE, multiple sclerosis, rheumatoid arthritis, inflammatory bowel disease, type 1 diabetes, young people The diagnosis is selected from sexually idiopathic arthritis and celiac disease.

[0452] The aspects and embodiments of this disclosure relate to one or more non-identical target antigens specific to one or more non-identical target antigens. This relates to CAR-expressing virus-specific immune cells containing CAR. In some embodiments, C Virus-specific immune cells containing CARs specific to CD30 are specific to antigens other than CD30. Includes CAR. For example, Example 4 of this specification includes CD30-specific CAR and CD19-specific This document describes virus-specific immune cells, including target CARs.

[0453] In some embodiments, cancers treated / prevented according to the present invention are one or more non-identical lesions. It is a cancer that contains cells expressing a target antigen. In some embodiments, the cancer is of non-identical target antigens. This is a type of cancer that exhibits both of these characteristics.

[0454] Uses related to the treatment / prevention of alloreactive immune responses CAR-expressing virus-specific immune cells and compositions of this disclosure are used in methods including allografting. For example, it can be used to treat / prevent diseases / conditions in a subject.

[0455] CAR-expressing virus-specific immune cells and compositions disclosed herein are alloreactive immune responses (especially In methods for reducing / preventing T cell-mediated alloreactive immune responses and their adverse consequences. It is useful.

[0456] Alloreactive T cells express CD30. Chan et al., J Immunol (2002) )169(4):1784-91 describes how CD30-expressing T cells respond to CD30 alloimmune responses. Subsequences of activated T cells (which also express CD25 and CD45RO), which play an important role. It has been identified as a set. CD30 expression and proliferation of CD30-expressing T cells are in response to the same antigen. The answer is that it increases. Chen et al., Blood (2012) 120(3):691-6 is CD CD30 expression on 8+ T cell subsets was identified as a potential biomarker for GVHD. Furthermore, CD30 has been proposed as a therapeutic target for GVHD.

[0457] Furthermore, virus-specific T cells are more restricted than polyclonal activated T cells (ATCs). It has a well-developed TCR repertoire and therefore does not induce GVHD after administration to allogeneic subjects. It is unlikely to occur. This is because of the G in the study of allogeneic EBV-specific T cells (EBVSTs). This is reflected in the low incidence of VHDs.

[0458] The CAR-expressing virus-specific immune cells and compositions of this disclosure are used in methods including allografting. It is particularly useful in the processing / production of allogeneic transplants.

[0459] In particular, CAR-expressing virus-specific immune cells and compositions are used in treatments including the administration of allogeneic materials. The manufacture and use of "ready-made" materials for use in therapeutic and preventive methods It is planned.

[0460] As described above, the CAR-expressing virus-specific immune cells of this disclosure are used to treat diseases caused by adoptive cell transfer. Useful for the treatment / prevention of disease / condition. The CAR-expressing virus-specific immune cells of this disclosure are useful for nourishing The recipient has low sensitivity to T cell-mediated alloreactive immune responses after transplantation, Therefore, enhanced proliferation / survival in recipients after transplantation, and superior treatment / prevention. It demonstrates effectiveness.

[0461] The CAR-expressing virus-specific immune cells and compositions of this disclosure also express the CAR-expressing virus of this disclosure. It is also useful in methods that include allogeneic transplantation of allogeneic cells other than virus-specific immune cells. In particular, the CAR-expressing virus-specific immune cells and compositions of this disclosure are allografts (cells, groups) Depleting the targets of tissues and organ populations and alloreactive immune cells (e.g., alloreactive T cells) It is useful for that purpose.

[0462] In such a method, CAR-expressing virus-specific immune cells and compositions are provided by the donor and and / or conditioning of the recipient, and / or alloreceptive immunosuppression after allografting. It is useful in allogeneic transplantation procedures to reduce / prevent disease responses.

[0463] The cells, tissues, and organs transplanted are, for example, immune cells (e.g., adoptive cell transplantation). Heart, lungs, kidneys, liver, pancreas, intestines, face, cornea, skin, hematopoietic stem cells (bone marrow), blood, hands, This includes legs, penis, bones, uterus, thymus, islets of Langerhans, heart valves, and ovaries. Allograft A group of cells, tissues, or organs that are transplanted may be called an "allotransplant."

[0464] The diseases / conditions treated / prevented by allogeneic transplantation are those for which allogeneic transplantation offers therapeutic or preventive benefits. It could be any disease / condition that would result in allografting. In some embodiments, allografting The diseases / conditions that are treated / prevented include, for example, T-cell dysfunction, cancer, infections, or autoimmunity. It could be an infectious disease.

[0465] T cell dysfunction is a disorder in which normal T cell function is impaired in the immune response to pathogenic antigens. Diseases / conditions that cause regulation, such as microorganisms, bacteria, and viruses. It is produced by infection with exogenous factors such as spores, or by certain disease conditions, for example. , produced by the host in some forms of cancer (e.g., forms of tumor-associated antigens) T cell dysfunction may include T cell depletion or T cell anergy. T cell depletion is C D8+ T cells do not proliferate, or they do not respond to antigen stimulation with cytotoxicity and cytokines. For example, this includes a state in which T cells do not exert their effector functions, such as IFNγ secretion. The T cells also produce one or more markers of T cell depletion, such as PD-1, CTLA-4, T cell dysfunction can be characterized by the sustained expression of LAG-3 and TIM-3. This manifests as an infection, or as the inability to initiate an effective immune response to the infection. Infections can be chronic, persistent, latent, or slow, and can be caused by bacteria, viruses, fungi, or This can be the result of a parasitic infection. Therefore, patients with bacterial, viral, or fungal infections Treatment can be provided to the patient. An example of a bacterial infection is Helicobacter pylori. Infections can include HIV, hepatitis B, or hepatitis C. Infections are one example. T-cell dysfunction may be associated with cancer, such as evading tumor immunity. Many Human tumors can produce tumor-associated antigens that are recognized by T cells and can induce an immune response. It manifests.

[0466] Infections can be, for example, bacterial, viral, fungal, or parasitic infections. In the embodiment, chronic / persistent infections, for example, infections in which such infections are associated with T cell dysfunction or T In cases related to cell depletion, it may be particularly desirable to treat it. T cell depletion is multi T cell function in various chronic infections (including viruses, bacteria, and parasites) and cancer. It is well established that the state is incomplete (Wherry Nature Immunity) nology Vol.12, No.6, p492-499, June 2011). Osamu Examples of bacterial infections that can be treated include Bacillus species, Bordetella pertussis, and Clostridium. The genera include Corynebacterium, Vibriocloella, Staphylococcus, and Streptococcus. Infections caused by these diseases include Escherichia, Klebsiella, and Prote. us, Yersinia, Erwina, Salmonella, Listeria s p, Helicobacter pylori, Mycobacteria (e.g., Mycob acterium tuberculosis) and Pseudomonas aeru Ginosa can be mentioned. For example, bacterial infections can be sepsis or tuberculosis. Examples of treatable viral infections include influenza virus, measles virus, and type B influenza virus. Hepatitis virus (HBV), Hepatitis C virus (HCV), Human immunodeficiency virus (HIV) ), lymphocytic choriomeningitis virus (LCMV), herpes simplex virus and human papillomavirus One example is infection caused by the fungal virus (HPV). Examples of treatable fungal infections include: This includes Alternaria sp, Aspergillus sp, and Candida. This includes infections caused by sp. and Histoplasma sp. Fungal infections are fungal It could be sepsis or histoplasmosis. Examples of treatable parasitic infections include malaria Infections caused by parasite species (e.g., Plasmodium falciparum, Plasmodium malariae, Plasmodium ovale) , Plasmodium vivax, or Plasmodium chabaudi This includes chabaudi. Parasitic infections include malaria, leishmaniasis and crested ibis. It could be a disease such as soplasmosis.

[0467] In some embodiments, the disease / condition is an autoimmune disease. In this context, treatment may aim to reduce the number of autoimmune effector cells. In one embodiment, the autoimmune disease is type 1 diabetes, celiac disease, Graves' disease, inflammatory bowel disease.

After performing the procedure, dilute 1.65 ml of the final cell suspension and add 220 ml of DMEM + 10%F Mixed with CS. Transfer 200 μl of this suspension to the wells of a 96-well plate. Approximately 30 cells were obtained per unit. Next, the best performing clone was selected, and retrovirus-containing cells were added. It was used to produce a supernatant. Then, the retrovirus-containing supernatant was collected and filtered. Stored at -80°C until use.

[0518] The retrovirus that codes for CD19.CAR, DN that codes for CD19.CAR A was created by cloning it into the pSFG retrovirus skeleton. CD19. Using a plasmid containing the CAR sequence, 85bCD19C, polyethyleneimine (PE HEK 293 Vec-RD114 cells were transfected using method I). The retrovirus-containing supernatant was collected, filtered, and stored at -80°C until use.

[0519] Example 2: Generation of CAR-expressing EBV-specific T cells Peripheral blood mononuclear cells (PBMCs) are subjected to standard Ficoll-Paque density gradient centrifugation. Therefore, it was isolated from blood samples obtained from healthy donors or lymphoma patients.

[0520] ATC generation Anti-CD3 (clone OKT3) and anti-CD28 agonist antibodies are administered at a concentration of 1 mg / ml. By adding 0.5 ml of a 1:1000 dilution, the wells of the tissue culture plate will be filled with Coat and incubate at 37°C for 2-4 hours, or overnight at 4°C, then 1 x 10 6 P BMC (in 2 ml of culture medium per well) RPMI medium, 44.5% Click's medium, 10% FBS and 1% Glutamate Culture on anti-CD3 / CD28 agonist antibody coated plates in (including x) The cells were stimulated in this way. The cells were maintained at 37°C in a 5% CO2 atmosphere. The next day, 1 ml of cell culture was performed. Prepare the culture medium by adding fresh fine-grained IL-7 at 20 ng / ml and IL-15 at 20 ng / ml. The cell culture medium was replaced. To maintain ATC during culture, the cell culture medium was changed every 2-4 days. And cytokines were supplemented as needed, or ATC was recovered and contained cytokines. The cells were re-seed in fresh cell culture medium. ATCs were collected and EBVST was administered between days 7 and 10. It was used in experiments for restimulation during the night.

[0521] General-purpose LCL LCL lacking surface expression of HLA class I and HLA class II (i.e., HLA-negative) LCL) is a lymphoblastoid cell line prepared by EBV transformation of B cells. Targeted knockout of genes encoding HLA class I and HLA class II molecules This was obtained by further modifying HLA-negative cells to add genes necessary for EBV replication. The cells obtained as a result of this method are referred to herein as universal. It is called ulcerative colitis (uLCL).

[0522] Proliferation and transduction of EBV-specific T cells (EBVSTs) PBMCs derived from healthy donors are used in CD45RA MACS microbeads (Milte CD45RA-expressing cells were depleted by magnetic cell separation using nyi Biotec. EBV-specific T cells are EBNA1 peptidone (JPT Cat No. PM). -EBV-EBNA1), LMP1 Pepmix (JPT Cat No. PM-EB V-LMP1), and LMP2 PEP obtained from JPT Technologies. Mix (JPT Cat No. PM-EBV-LMP2) (11 amino acid duplication 15 m - Using an amino acid peptide library (including the complete amino acid sequence of the related antigen), 44. 5-47% Advanced RPMI, 44.5-47% Click's medium, 10% FBS or 5% growth factor-rich additive, and IL-7 (10 ng / ml) and IL-15 In cell culture medium containing 1% GlutaMax with (10 ng / ml) added, 2 x 10 6 CD45RA-depleted PBMCs (2 ml of culture medium per well) can be stimulated to promote growth. The EBVST was maintained at 37°C in a 5% CO2 atmosphere.

[0523] After 4-6 days, the EBVST will be retrocoded with the CAR described in Example 1 as follows: The virus was introduced into the body.

[0524] In a non-tissue culture treated 24-well plate pre-coated with retronectin (Takara), Rovirus-containing supernatant (0.5-1 ml per well) was added. Plates were heated to 2000 x g. After centrifugation for 60-90 minutes, remove the retroviral supernatant and 0 cells per well. 0.25~0.5×10 6 The cells were replated.

[0525] After 8-10 days of culture, the irradiated peptide pulsed self-activated T4 was used in the presence of uLCL. The cells were re-stimulated by co-culturing them with cells (ATC). In short, 2 × 10 6 of ATC, Pepmix (1 x 10 6 (10 ng of Peptomix mixture per ATC) Both samples were incubated in CTL medium at 37°C for 30 minutes, followed by irradiation with 30 Gy, and then harvested. Next, the peptide processing ATC used IL-7 (10 ng / ml) and IL-15 (1 In culture in CTL media containing 00 ng / ml and in uLCL (irradiated with 100 Gy) The ratio of respondent cells was: peptide-modified ATC:1:1:5 (irradiated uLCL) and mixed. Physically, 1 x 10 5 Responding cells, 1 × 10¹ 5 Peptide pulse ATC and 0.5× 10 6 Irradiated uLCL was cultured in 2 mL of CTLs in a 24-well tissue culture plate. It was cultured underground.

[0526] To maintain EBVST during culture, the cell culture medium and cytoplasm should be changed every 2-4 days. The cytokines were replenished as needed, or EBVST was recovered and fresh cells containing cytokines were used. The cells were re-seeded in culture medium. EBVSTs were collected, and the mixed lymphocyte reaction (M) was observed on days 15-20. It was used in the LR assay.

[0527] Example 3: CD30 special cell that eliminates allogeneic reactive T cells and protects allogeneic VSTs from rejection. Evaluation of the capabilities of different CARs The inventors have demonstrated the ability of VST to resist homogeneous rejection in vitro with respect to CD30.C. The effect of AR expression was investigated.

[0528] Generation of primed alloreactive T cells 10 EBVSTs were produced using 1-2x EBVSTs derived from the same healthy donor. 6 PB Irradiate MC (per well) with 30 Gray, and 1x10 from a mismatched donor. 6 P BMC (per well) (with various HLA-A2 expression levels), 44.5% advanced RPMI, 44.5% click medium, 10% serum, and IL-7 (10 ng / ml) In cell culture medium containing 1% glutamax supplemented with IL-15 (10 ng / ml) Co-cultured. Primed alloreactive T cells grown from mismatched donor PBMCs. The cells are 0.5 × 10 6 Cells (in 2 ml of cell culture medium) are treated with anti-CD3 / CD28 agonists. The cells were re-stimulated by seeding on antibody-coated plates on days 6-10. To maintain the allore-reactive T cells, the cell culture medium and cytokines are changed every 2-4 days. Supplementation was performed as needed, or alloreactive T cells were collected and fresh cytokines were added. The cells were re-seeded in cell culture medium. Alloreactive T cells were collected and subjected to EBVS between 13 and 17 days. It was used in a mixed lymphocyte reaction (MLR) assay using T.

[0529] To evaluate allore rejection in vitro, 0.0% of the sample is derived from an HLA-A2-negative control. 2 x 10 OOBPBMC alloreactive T cells are mixed lymphocyte reactant (MLR) aggregate. In I: (i) HLA-A2 positive targets used to prime alloreactive T cells 0.2x10 generated from PBMC 4 EBVST, or (ii) HLA-A2 positive targets used to prime alloreactive T cells 0.2 × 10⁻¹⁰ PBMC generated from PBMC 4 EBVST is a CD30-specific CAR The structure was further modified to incorporate new traits.

[0530] Human IL-7 (10 ng / ml) and IL-15 (10 ng / ml) were subjected to MLR assay. Added.

[0531] Flow cytometry analysis was performed 7 days later, and the absolute number of cells was determined using counting beads. T cells derived from different sources were co-cultured and then aggregated based on HLA-A2 expression. It was possible to identify it within the group. Gallios Flow Cytometer (B Using eckman Coulter) to retrieve events, Kaluza Anal ysis Software (Beckman Coulter) for data analysis and graphics Used for displaying "F".

[0532] As shown in Figure 1, the number of non-transduced (NT) EBVSTs derived from HLA-A2 positive targets is After co-culturing alloreactive T cells derived from an HLA-A2-negative control for 7 days (lower left panel), Compared to when cultured in the absence of alloreactive T cells (upper left panel), the reduction was significant. In contrast, the number of CD30.CAR EBVSTs was increased in the absence of alloreactive T cells during culture. Compared to the case where (upper right panel), after 7 days of co-culture with alloreactive T cells (lower right panel) It increased to (ru).

[0533] Figure 2 shows the quantification of flow cytometry data. (Untransduced EBVST(NT)) It was largely eliminated in the presence of alloreactive T cells, but CD30.CAR-expressing EBVST It was resistant to elimination by alloreactive T cells (Figure 2A). In addition, alloreactive T Quantitative analysis of the cell population (CD3+, HLA-A2 negative) is performed using CD30.CAR EBVST. We revealed that the number of allogeneically reactive T cells is reduced compared to transduction EBVST conditions. (Figure 2B).

[0534] Therefore, EBVST expressing CD30.CAR reduces the number of alloreactive T cells. It has been shown to possess the ability to prevent allergic reactions and to be protected from allergic rejection.

[0535] Example 4: EBV-specific T19 expressing CD19-specific CAR and CD30-specific CAR Cell characterization The inventors manipulated the system to express both CD19.CAR and CD30.CAR. We generated and characterized virus-specific T cells, and observed that they exhibited allogeneic effects in mixed lymphocyte reactions. We investigated whether reactive T cells could be eliminated.

[0536] In short, HLA-A2 positive target cells depleted of CD19 and CD56 expression cells Next 1x10 5 The population of PBMCs was co-cultured in a mixed lymphocyte reaction (MLR) assay. Raised: (i) 0.1 x 10⁶ PBMCs generated from HLA-A2 negative subjects 5 EBV ST, or (ii)(a)HLA further transfected in a construct encoding CD30.CAR - 0.1 × 10⁶ generated from PBMCs of A2-negative subjects. 5 EBVST(b)CD19. CAR, or (c) both CD30.CAR and CD19.CAR (CD30+CD19 .CAR).

[0537] Human IL-2 was added to the MLR assay at a concentration of 20 IU / ml.

[0538] As shown in Figure 3, CD30.CAR EBVST (upper right panel) and CD30+CD1 9. EBVST (bottom right panel) with both CAR is not transduced (NT)E Compared to BVST (top left panel) and CD19.CAR EBVST (bottom left panel), By day 7, HLA-A2+ alloreactive T cells (distinguished by the activation marker CD71) This significantly reduced the rate of rejection (and thus avoided rejection).

[0539] Therefore, the inventors used EBVSTs transduced with both a CAR specific for the target antigen (CD19 in this example) and a CD30-specific CAR to provide a novel approach for generating "off-the-shelf" CAR T cells specific for a given target antigen. The ability of such dual CAR-EBVSTs to eliminate allogeneic reactive T cells in vitro suggests that they can avoid rejection in vivo and persist for long periods in allogeneic recipients.

[0540] Example 5: Cancer treatment using CD30.CAR EBVST 5.1 Preparation and Characterization of CD30.CAR EBVST from Health Provider Subjects price CD30.CAR EBVSTs were manufactured in a GMP facility. After obtaining informed consent, approximately 250 - 400 mL of blood was collected from 7 healthy blood bank-approved donors according to the guidelines established by the Helsinki Declaration.

[0541] Peripheral blood mononuclear cells (PBMCs) were isolated from the blood by density gradient centrifugation. CD45RA-expressing cells were depleted from the PBMCs using magnetic cell separation with clinically graded anti-CD45RA antibody conjugated to magnetic beads and a Miltenyi depletion column (Miltenyi Biotec, Bergisch Gladbach, Germany).

[0542] 1.5 - 2.5x10 depleted of CD45RA post cells 7 PBMCs were resuspended in 47.5% Advanced RPMI, 47.5% Click's (EHAA) medium (Irvine Scientific), 2 mM L-glutamine (Thermo Fisher Sci (entific) and 5% human platelet lysate (HPL; Sexton Biotope) Seeds were seeded in 30 ml of culture medium containing (ingredients) and placed in a G-Rex10 container. Supplemented with IL-7 (10 ng / ml) and IL-15 (10 ng / ml), resulting in 11 amino acid duplication. Stimulation by a duplicate peptide library (Pepmix) containing 15 M amino acids activates The process involved the entire protein sequence of the associated antigens: EBNA1, LMP1, LMP2, BARF. 1, BZLF1, BRLF1, BMLF1, BMRF1, BMRF2, BALF2, BN Pepmix compatible with LF2a and BNLF2b is manufactured by JPT Technologie. Obtained from s (Berlin, Germany). Stimulus is stimulated 1 x 10 6 Cell A For each antigen, 5 ng of peptomycete was used (i.e., CD45RA-positive cells) Depleted 2x10 7 For stimulation using PBMC, each Pepmix 100 (ng was used). Stimulated culture was maintained at 37°C in a 5% CO2 atmosphere.

[0543] After 4-6 days, the EBVST produced by the stimulated culture described above is as follows: Sea urchin was transduced with the retrovirus encoding the CAR described in Example 1. 2 ml Mix the retrovirus-containing supernatant with 150 μg of Vectofucin-1 in a volume of 2 ml. A final volume of 4 ml was obtained and incubated at room temperature for 5-30 minutes. Then, retrow Add the Virus:Vectofucin-1 mixture to 8.5 ml of culture medium in a T75 container (as described in the previous section). (Included) 7~10×10 6 The solution was added to the cells. The culture was maintained at 37°C in a 5% CO2 atmosphere. Ta.

[0544] During the 8th to 10th day of culture, 1-2 × 10⁶ units produced by the transduction described in the previous section were obtained. 7 of CD30.CAR EBVST CD30.CAR EBVST in G-Rex100 container Transfer to C for irradiated uLCL in a range of 1:2 to 1:5 (typically about 1:3). D30.CAR EBVST ratio, irradiated (100 Gray) uLCL (Example) Restimulation was performed by co-culture with (as described in 2). ULCL was EBV antigen and CD30, and CD30.CAR expresses other co-stimulatory molecules, and therefore, antigen stimulation and co-stimulation are associated with CD30.CAR. It provides EBVST, and the potency of CD30.CAR EBVST without losing EBV specificity. It induces proliferation.

[0545] Restimulation culture is established using 200 ml of culture medium (as described in paragraph 3 of section 5.1), and if necessary... Additional culture medium was added accordingly. After 7-12 days, CD30.CAR EBVST was collected. It was then cryopreserved for subsequent injections.

[0546] CD30.CAR EBVST prepared from four representative healthy donors was used in Ability to proliferate in vitro, CD30 expression in vitro, and against CD30-negative cancer cell lines Cytotoxicity and specificity to different EBV antigens were evaluated.

[0547] Analysis of CD30.CAR EBVST proliferation The proliferation of CD30.CAR EBVST was observed at various time points during culture (0, 6, 10, 17, The number of cells is determined by counting them using a hemocytometer on days 18 and 19, and the cumulative number is then determined. The magnification was calculated.

[0548] Figure 4 shows CD30.CAR EBVS produced from four different healthy donor subjects. T is sufficient to achieve the therapeutic dose of CD30.CAR EBVST within ~17~20 days and shows sufficient proliferation in in vitro culture. The proliferated cells expressed CD30.CAR in 77% - 99 % of the cells (data not shown).

[0549] Analysis of CD30.CAR EBVST cytotoxicity The cytotoxic specificity of CD30.CAR EBVST was measured using a chromium-51 ( 51 chromium) release assay. Briefly, target cells, either CD30-negative BJAB Burkitt lymphoma cells or CD30-positive HDLM2 Hodgkin lymphoma cells, were incubated with 51 Cr for 1 hour. Non-transduced EBVST or CD30.CAR-transduced EBVST was used as effector and incubated with the target at effector-to-target ratios of 40:1, 2 0:1, 10:1, 5:1 and 2.5:1 in the wells of a 96-well plate. After 4 - 6 hours of culture, the co-culture supernatant was collected and chromium release was detected with a gamma counter. The percentage of specific lysis was determined from the average of 3 times using the following chemical formula: [(experimental release - spontaneous release) / (maximum release - spontaneous release)]×100. 51 of chromium release was detected. The percentage of specific lysis was determined from the average of 3 times using the following chemical formula: [(experimental release - spontaneous release) / (maximum release - spontaneous release)]×100. release was detected. The percentage of specific lysis was determined from the average of 3 times using the following chemical formula: [(experimental release - spontaneous release) / (maximum release - spontaneous release)]×100.

[0550] Figure 5 shows that CD30.CAR EBVST was substantially non-cytotoxic to cells of the CD30-negative Burkitt lymphoma BJAB cell line, but showed high cytotoxicity to cells of the CD30-positive Hodgkin lymphoma HD LM2 cell line.

[0551] Analysis of the reactivity of CD30.CAR EBVST to EBV antigen IFN-γ ELISpot assays were performed to prepare from 4 different healthy donor subjects The response of CD30.CAR EBVST to stimulation with EBV antigen was evaluated.

[0552] EBV latent cycle antigens (EBNA1, LMP1, LMP2, and BARF1) and EB V lytic cycle antigens (BZLF1, BRLF1, BMLF1, BMRF1, BMRF2, Regarding BALF2, BNLF2a, and BNLF2b), Pepmix (JPT Tec In response to stimuli (obtained from hnologies, Berlin, Germany), IFN-γ production was measured. In short, CD30.CAR EBVST was measured in 5 × 1 0 4 Cells / well, wells of a 96-well multiscreen plate (MilliporeSigma) The substrate was plated in two strands. Stimulation was performed using a total of 0.1 μg of peptide per well. The process involved incubation in 5% CO2 at 37°C for 16-20 hours, followed by IFN-γ+ Plates were deployed for spot measurements, and Zernet Consulting (New Zealand) was used for quantification. It was sent to Fortley, Jersey. The frequency of antigen-specific reactions was 5 × 10⁻⁶. 4 per cell It is represented as a Spot Forming Unit (SFU).

[0553] Figure 6 shows CD30.CAR EBVS produced from four different healthy donor subjects. This indicates that T retained its specificity for the EBV antigen.

[0554] All four CD30.CAR EBVST strains possess both latent and soluble EBV antigens. 10 in response to stimulation 5 Spot-forming units exceeding 100 IFNv per cell ( It produces SFUs and exceeds 20% of the CD30-positive Hodgkin lymphoma cell line HDLM2. A functional release group that produces specific cell lysis in an effector-to-target ratio of 20:1. I passed the preliminary exam.

[0555] 5.2 CD30.CAR EB as allogeneic adoptive cell therapy for CD30+ lymphoma VST administration CD30+ refractory or relapsed Hodgkin lymphoma, non-Hodgkin lymphoma, ALK-positive undifferentiated Patients with T-cell lymphoma, ALK-negative anaplastic T-cell lymphoma, or other peripheral T-cell lymphomas Patients aged 12 to 75 years were eligible for treatment in this study.

[0556] Cyclophosphamide (Cy: 500 mg / m²) 2 ( / day) Fludarabine (Flu:30m) g / m 2 It was administered three times a day in combination with ( / day) and induced lymphopenia, but CD30.C Although it was completed 48 hours before the AR EBVST intravenous infusion, it was completed by 2 weeks before the intravenous infusion. Ta.

[0557] On day 0 of the trial, patients received intravenous infusions of 1-50 ml over approximately 1-10 minutes. Therefore, the patient received a single dose of the planned allogeneic CD30.CAR EBVST. Administer CD30.CAR EBVST with the best HLA class I and class II match. did.

[0558] In this study, allogeneic CD30.CAR EBVST cells were administered to a total of five patients. 3 For example, 4 x 10 7 A dose of CD30.CAR EBVST cells (DL1) was administered. For example, 1 × 10 8 A dose of 2 (DL2) of CD30.CAR EBVST cells was administered.

[0559] Monitoring was conducted for the administration of blood products, except that the injection was administered by a physician. The procedure was performed according to facility standards. Patients were monitored for at least 3 hours after injection. Clinical status Patients were evaluated for adverse events, including changes in clinical laboratory data. In particular, some CARs - Cytokine release syndrome (CRS) and neurotoxicity observed in T-cell immunotherapy We evaluated patients regarding the correlation with sex.

[0560] Blood samples were collected from patients at the following points in time: before the study, 3-4 hours after injection, and on day 0. 1, 2, 3, 4, and 6 weeks and 3 months after cytoplasmic injection. Sustained CD30.CAR EBVST. Samples were analyzed to evaluate their properties and effectiveness.

[0561] None of the patients experienced dose-limiting toxicity, nor did any cytokine release syndrome of any grade. No CRS (Chronic Surgical Condition) or graft-versus-host disease (GVHD) was observed.

[0562] Clinical responses in patients treated with allogeneic CD30.CAR EBVST Diagnostic imaging is performed to detect measurable disease before injection and at 6-8 weeks after injection on day 0. For patients and their treatment (via PET scan, CT scan, MRI, and nuclear imaging) The response was recorded.

[0563] Patient #1 received an intravenous injection of 11.9 mCi of FDG into the left cubital fossa (blood glucose level at the time of injection was 9 mCi). (The level was 9 mg / dL). PET and CT images were obtained from the middle cranial vault to the proximal femur, and images were taken. The fusion process was followed by polyhedral reconstruction in the axial, coronal, and sagittal planes, as well as three-dimensional reconstruction.

[0564] Patient number 2 received an intravenous injection of 7.29 mCi of FDG (blood glucose level at the time of injection was 99 mg / (It was dL). Approximately 60 minutes later, using a PET-CT scanner with CT attenuation correction technology... Images were obtained from the base of the skull to the proximal thigh. CT slices were obtained using a low-dose method, and multiple images were taken. A planar reformatted image was obtained.

[0565] Figures 7 and 8 show the clinical response in two patients treated with CD30.CAR EBVST. The answer is shown. The image of patient #1 shows the resolution of several areas of the disease, and the image of patient #2 shows the disease A significant decrease in the number of patients was observed, and in these patients, allogeneic CD30.CAR EBVST To demonstrate the therapeutic effectiveness of the treatment.

[0566] Analysis of the copy number of the CD30.CAR vector after administration Real-time qPC for the embedded genome of the retrovirus encoding CD30.CAR Quantitative analysis was performed using R. PBMCs were measured at several time points (before lymphocyte depletion, 3 hours, 1 week, Peripheral blood samples taken from patients at weeks 2, 3, 4, 6, and 3 months were used to obtain a single sample. I released it. I followed the manufacturer's instructions for the QIAamp DNA Blood Mini Kit. After extracting DNA from PBMCs using (Qiagen), the DNA was then transferred to a retroviral vector. Using primers and probes (applied biosystems) complementary to specific sequences The DNA was amplified. A standard curve was created using serial dilutions of the plasmid encoding the transgene. Established. Amplification was performed according to the manufacturer's instructions using the ABI7900HF real-time PCR system. The procedure was carried out using Applied Biosystems (M).

[0567] Figure 9 shows the vector copy number of the CD30.CAR transgene in patient #1 and patient #2. CD30.CAR EBVST does not proliferate in vivo, and these patients' end-stages This suggests that it becomes rapidly undetectable in peripheral blood.

[0568] Analysis of epitope diffusion in patients administered allogeneic CD30.CAR EBVST To assess epitope diffusion, immune cells were collected from patient #1 at several time points, and tumor Stimulation with ulcer-associated antigens and the reactions before and after infusion of allogeneic CD30.CAR EBVST I decided on my gender.

[0569] PBMC at several points in time (Pre-lymphodepletion, 3 hours, 1 Peripheral blood samples collected from patients at week 1, week 2, week 3, week 4, week 6, and month 3. Isolating from and essentially performing the ELISpot assembly as described in Example 5.1 above It was used in I, however, PBMC was 3 x 10 per well 5 Sowed and EBV latent In addition to evaluating soluble antigens, PBMCs were stimulated using two additional antigen groups; (1 ) A pool of peptide mix antigens derived from "other viruses" (adenovirus protein He xon and Penton, as well as CMV protein PP65), and (2) tumor-related TAA (Traditional Antigens) MAGE-A4, NY-ESO, PRAME, SSX2, and Survival A pool of Pepmix that corresponds to [the product / service].

[0570] Figure 10 shows that patient #1 did not show a response to tumor-associated antigens at any point in time. This indicates that there was no epitope diffusion in patient #1. Treatment with allogeneic CD30.CAR EBVST targets the patient's immune system and these other tumor antigens. This suggests that the individual was not sensitized to the substance.

[0571] 5.3 Conclusion The inventors have found that CD30.CAR EBVST produced from a healthy donor is a CD According to their use as ready-made treatments for patients with 30+ cancers, EBV specificity With the ability to retain and eliminate CD30-positive tumor cells, they are expanded to a sufficient number, and they This demonstrated that it is possible to save the functions of both TCR and CD30.CAR.

[0572] CD30.CAR EBVST is safe and in viv It was found to show therapeutic effect against CD30-positive lymphoma in peripheral blood CAR Despite the limited persistence of expression cells, and the spread of epidemiologically to other tumor-associated antigens... Despite the lack of evidence for the drug, a clinical response was observed.
