Abstract
Description
[Technical Field]
[0001] The present invention relates to immune cells capable of antibody-dependent cellular cytotoxicity and comprising a nucleic acid sequence encoding an antigen-binding molecule. The present invention also relates to methods for producing the immune cells and medical uses of the immune cells. [Background technology]
[0002] Alphabeta (ab) T cells expressing chimeric antigen receptors (CARs) form an important part of the immunotherapy toolkit. By expressing CARs in abT cells, the antigen specificity of the abT cells can be altered. In this way, the subject's adaptive immune system can be reprogrammed to target antigens of particular interest in the subject, such as tumor antigens.
[0003] Recently, strategies to improve the therapeutic potential of CAR abT cells have been developed. In particular, "armored" CAR abT cells have been generated. Armored CAR abT cells have the ability to secrete function-enhancing molecules. For example, CAR abT cells can secrete cytokines that enhance their therapeutic efficacy. CAR abT cells can secrete peptides that inhibit protein kinase A (Newick et al., Cancer Immunol Res, June 2016, 4(6):541-551). CAR abT cells can also secrete molecules that overcome immune checkpoints. For example, Rafiq et al. (Nature Biotechnology, August 13, 2018, Vol. 36(9): pp. 847-856) equipped CAR abT cells with the ability to secrete anti-PDL1 antibodies, and Li et al. (Clinical Cancer Research, November 2017, Vol. 23(22): pp. 6982-6992) engineered CAR abT cells to secrete scFv specific for PD-1 on the effector cell surface. Summary of the Invention [Problem to be solved by the invention]
[0004] In contrast to abT cells, gamma delta (gd) T cells are a relatively overlooked innate-like immune cell subset. Unlike abT cells, gdT cells (especially Vδ2+ gdT cells) are capable of potent antibody-dependent cellular cytotoxicity (ADCC) against antibody-labeled tumor cells. Therefore, gdT cell infiltration into tumors correlates with favorable clinical outcomes, and gdT cells have potential in cancer immunotherapy. Myeloid cells are also capable of ADCC and can be used in cancer immunotherapy. To optimize their therapeutic potential, it is desirable to engineer gdT cells and myeloid cells to secrete molecules that enhance their anticancer activity. [Means for solving the problem]
[0005] The present inventors have demonstrated that immune cells capable of ADCC can be engineered to secrete antigen-binding molecules (e.g., antibodies or antibody-like proteins, e.g., scFv-Fc) that target antigens expressed in the tumor microenvironment. Secretion of the antigen-binding molecules can enhance the anti-cancer activity of the immune cells. For example, the secreted antigen-binding molecules can increase target cell killing by ADCC. This exemplary mechanism is shown in Figure 1, in which scFv-Fc secreted by engineered immune cells (e.g., gdT cells) marks target cells expressing the cognate antigen for ADCC. This allows the engineered immune cells to kill the target cells by ADCC. Bystander, non-engineered immune cells can also exert ADCC against target cells. In this way, the antigen-specific cytotoxicity of the engineered bystander immune cells is improved. Therefore, administration of engineered immune cells to a subject provides improved anti-cancer therapy.
[0006] Thus, the present invention provides: - an immune cell capable of ADCC and comprising a nucleic acid sequence encoding an antigen-binding molecule comprising an antigen-binding region; - a method for producing an immune cell of the present invention, comprising introducing a nucleic acid sequence encoding an antigen-binding molecule into an immune cell; - a method of treating a disease in an individual, the method comprising administering to the individual a therapeutically effective number of immune cells of the invention; and - an immune cell of the invention for use in a method of treating a disease in an individual, the method comprising administering to the individual a therapeutically effective number of the immune cell. [Brief explanation of the drawings]
[0007] [Figure 1] FIG. 1 shows an example of a proposed mechanism by which scFv-Fc secreted by γδ T cells engages Fc receptors on ADCC-competent cells in the tumor microenvironment. [Figure 2] Figure 1 shows the binding of scFv-Fc to cells expressing target antigens as detected by flow cytometry. CEA+ CAPAN-1 cells or CEA- HELA cells were incubated with supernatant from V52 cells or Jurkat cells secreting anti-CEA scFv-Fc fusion protein. Anti-human Fc was used to detect binding of the scFv-Fc fusion protein. Purified scFv fusion protein was used as a positive control. Similar experiments were performed using supernatant from GD2+ / - SupT1 cells and V52 cells secreting anti-GD2 scFv-Fc fusion protein. In this case, clinical-grade dinutuximab (anti-GD2) was used as a positive control. [Figure 3] FIG. 1 shows the experimental set-up showing the conditions used in the cytotoxicity assay to test the direct and indirect cytotoxic benefits of scFv-Fc fusion protein expression. [Figure 4A-C]Figure 1 shows cytotoxicity in cell contact-dependent and -independent settings. All cytotoxicity experiments were performed at a 1:1 effector:target ratio with 18 h co-culture. Target cells were labeled with CellTrace Violet™ and killing was detected by staining with GhostRed fixable viability dye. Target cell death is shown as all values minus background death (in the absence of effectors).

[Figure 5] FIG. 1 shows IFNγ concentrations in the supernatant after 18 hours of co-culture of CEA+ CAPAN-1 or CEA- HELA cells with non-transduced V52 cells, where anti-CEA scFv-Fc-secreting V52 cells or a non-transduced control were sequestered behind a semi-permeable membrane. [Figure 6]Figure 1 shows the binding of anti-GD2 antibody (SEQ ID NO: 17) produced by 293T cells to GD2+ / - target cells as detected by flow cytometry. 293T cells were treated with decreasing volumes of lentivirus encoding the whole anti-GD2 antibody 14G2a. Isogenic SupT1_wt(GD2-) or Sup T1_GD2(GD2+) was incubated with supernatants from transduced 293T cells. Antibody binding was detected using a PE-conjugated anti-human Fc antibody. A pure anti-GD2 antibody (dinutuximab, ch14.18, clone 14G2a) was used as a positive control. Antibodies were detected in the supernatants of transduced 293T cells at levels dependent on the amount of virus applied. [Figure 7] Figure 1 shows binding of antibodies produced by γδ T cells to cells expressing the target antigen. Isogenic SupT1_wt(GD2-) or Sup T1_GD2(GD2+) cells were incubated with supernatant from transduced V52 to express whole anti-GD2 antibody (clone 14G2a). Antibody binding was detected using an anti-human IgG secondary antibody; pure anti-GD2 (dinutuximab, ch14.18, clone 14G2a) was used as a positive control. [Figure 8A] Figure 1 shows cytotoxicity in cell contact-dependent and -independent settings. All cytotoxicity experiments were performed at a 1:1 effector:target ratio with 18 h co-culture.

[0011] All publications, patents, and patent applications cited herein, whether supra or infra, are hereby incorporated by reference in their entirety.
[0012] immune cells The present invention provides immune cells capable of ADCC and comprising a nucleic acid sequence encoding an antigen-binding molecule. The immune cells can be any immune cells capable of ADCC. Immune cells capable of ADCC are known in the art.
[0013] ADCC is a well-known mechanism of adaptive cellular immunity. During ADCC, immune effector cells actively lyse target cells whose surface antigens are bound by specific antibodies. Specifically, antibodies bind to their cognate antigens on the surface of target cells. Fc receptors present on the surface of immune effector cells recognize the Fc region of the bound antibody. Cross-linking of Fc receptors induces the formation of a lytic synapse between the immune effector cell and the target cell, causing the immune effector cell to degranulate lytic granules. Thus, apoptosis of the target cell is induced. Immune effector cells capable of ADCC are known to include natural killer (NK) cells, macrophages, neutrophils, and eosinophils. gdT cells are also capable of ADCC.
[0014] The immune cells can be from any species, for example, human, dog, cat, mouse, rat, pig, sheep, cow, goat, or horse. The immune cells are typically human immune cells. The immune cells can be dog, cat, mouse, pig, sheep, goat, cow, or horse immune cells.
[0015] Preferably, the immune cells are not abT cells. abT cells are T cells that have a T cell receptor (TCR) containing an alpha chain and a beta chain. They are usually activated in an MHC-dependent manner. ADCC has not been reported for abT cells. abT cells are often considered "conventional" T cells.
[0016] The immune cells can be gdT cells. gdT cells are T cells that have a gdT cell receptor (TCR) on their surface. That is, gdT cells have a TCR that includes a gamma chain and a delta chain. Thus, gdT cells are structurally distinct from abT cells. gdT cells are also functionally distinct from abT cells. In particular, gdT cells are capable of ADCC. gdT cells are typically activated in an MHC-independent manner. gdT cells are often considered "non-conventional" T cells.
[0017] There are several subsets of gdT cells. For example, gdT cells can be V52+ gdT cells, V51+ gdT cells, or V51- / V52- gdT cells. Preferably, gdT cells are V52+ gdT cells. V52+ gdT cells, V51+ gdT cells, and V51- / V52- T cells all have excellent ADCC capabilities and exhibit good anti-tumor cytotoxicity.
[0018] Methods for expanding gdT cells are known in the art. For example, gdT cells can be expanded by culturing them in the presence of IL-2 and zoledronic acid (Fisher J et al., Effective combination treatment using anti-GD2 ch14.18 / CHO antibody with V52+ γδT cells in Ewing sarcoma and neuroblastoma. Oncoimmunology 2015 Apr. 27; Vol. 5(1): e1025194). Thus, gdT cells are readily available for use in the present invention.
[0019] The immune cells can be bone marrow cells. Bone marrow cells are cells derived from common myeloid precursor cells, such as platelets, erythrocytes, mast cells, macrophages, basophils, neutrophils, and eosinophils. ADCC has been reported for macrophages, basophils, neutrophils, and eosinophils. Therefore, preferably, the bone marrow cells are macrophages, basophils, neutrophils, or eosinophils. Methods for isolating and expanding bone marrow cells are known in the art.
[0020] Natural killer (NK) cells are also capable of ADCC. The immune cells can be NK cells. NK cells are a class of innate immune lymphocytes that play a role in immunity against various diseases. For example, NK cells play a role in detecting and controlling cancer and killing virus-infected cells. Methods for isolating and expanding NK cells are known in the art.
[0021] Preferably, the immune cells do not express a chimeric antigen receptor (CAR), and therefore preferably the immune cells are not CAR T cells.
[0022] Nucleic acid sequence The immune cells of the present invention comprise a nucleic acid sequence encoding an antigen-binding molecule. The nucleic acid sequence may comprise DNA. The nucleic acid sequence may comprise RNA. The nucleic acid sequence may comprise DNA and RNA.
[0023] An immune cell may contain one or more nucleic acid sequences, each encoding an antigen-binding molecule. For example, an immune cell may contain two or more, three or more, four or more, five or more, six or more, seven or more, eight or more, nine or more, ten or more, fifteen or more, or twenty or more nucleic acid sequences, each encoding an antigen-binding molecule. When an immune cell contains multiple nucleic acid sequences, each encoding an antigen-binding molecule, the antigen-binding molecules encoded by each nucleic acid sequence may be the same or different. Preferably, each of the antigen-binding molecules is different. Preferably, each of the antigen-binding molecules is specific for a different antigen. Preferably, the antigen is a tumor antigen. The antigen may be expressed on or by cancer cells. The antigen may be expressed on or by non-cancer cells in the tumor microenvironment. The antigen may be secreted into the tumor microenvironment.
[0024] Each nucleic acid sequence may encode one or more antigen-binding molecules. For example, the nucleic acid sequence may encode two or more, three or more, four or more, five or more, six or more, seven or more, eight or more, nine or more, ten or more, fifteen or more, or twenty or more antigen-binding molecules. When a nucleic acid sequence encodes multiple antigen-binding molecules, each of the antigen-binding molecules can be the same or different. Preferably, each of the antigen-binding molecules is different. Preferably, each of the antigen-binding molecules is specific for a different antigen. Preferably, the antigen is a tumor antigen. The antigen may be expressed on or by cancer cells. The antigen may be expressed on or by non-cancer cells in the tumor microenvironment. The antigen may be secreted into the tumor microenvironment.
[0025] The nucleic acid sequence may comprise an exogenous promoter sequence to which the sequence encoding the antigen-binding molecule is operably linked. The exogenous promoter may be an inducible promoter. Alternatively, the nucleic acid sequence may lack an exogenous promoter sequence. In this case, the nucleic acid sequence may be integrated into the genome of an immune cell such that expression of the antigen-binding molecule is controlled by an endogenous promoter in the genome. Activation of the exogenous or endogenous promoter may be controlled by an inducible signaling pathway. For example, the exogenous or endogenous promoter may be activated upon engagement of a synNotch receptor with a cognate antigen.
[0026] The nucleic acid sequence can be integrated into the genome of the immune cell. Alternatively, the nucleic acid sequence cannot be integrated into the genome of the immune cell. If the nucleic acid sequence is not integrated into the genome of the immune cell, it can be contained in a plasmid, vector, or artificial chromosome. The vector can be a viral vector or a non-viral vector. The artificial chromosome can be a yeast artificial chromosome (YAC), a bacterial artificial chromosome (BAC), or a human artificial chromosome (HAC). Preferably, the artificial chromosome is a HAC.
[0027] antigen binding molecule The immune cells of the present invention comprise a nucleic acid sequence encoding an antigen-binding molecule.
[0028] An antigen-binding molecule comprises an antigen-binding region. An antigen-binding region is a region of an antigen-binding molecule that can specifically bind to one or more antigens. For example, an antigen-binding region may be capable of specifically binding to two or more, three or more, four or more, five or more, six or more, seven or more, eight or more, nine or more, or ten or more different antigens. Exemplary antigen-binding regions are known in the art and include at least scFv (single-chain variable fragment), Fab, modified Fab, Fab', modified Fab', F(ab')2, Fv, dAb, Fd, dsFv, ds-scFv, scFv2, bispecific T-cell engagers, nanobodies, DARPins, antibody mimetics, diabodies, triabodies, and tetrabodies. Thus, the antibody binding region can comprise an scFv, Fab, modified Fab, Fab', modified Fab', F(ab')2, Fv, dAb, Fd, dsFv, ds-scFv, scFv2, bispecific T-cell engager, nanobody, DARPin, antibody mimetic, diabody, triabody, or tetrabody, alone or in any combination. The antigen-binding molecule can comprise an scFv, Fab, modified Fab, Fab', modified Fab', F(ab')2, Fv, dAb, Fd, dsFv, ds-scFv, scFv2, bispecific T-cell engager, nanobody, DARPin, antibody mimetic, diabody, triabody, tetrabody, or polypeptide ligand of a receptor expressed on the surface of a cell targeted by an immune cell, alone or in any combination.
[0029] Preferably, the antigen-binding molecule comprises an antigen-binding region comprising an scFv. The antigen-binding region may comprise two or more, for example, three or more, four or more, five or more, six or more, seven or more, eight or more, nine or more, or ten or more scFvs. scFvs are known in the art. An scFv is a molecule comprising a variable region (V) of an antibody light chain. L ) linked to the variable region of the heavy chain (V H ) is a fusion protein containing H and V Lare connected by a linker peptide. The linker peptide can be about 5 to about 30 amino acids in length. For example, the linker peptide is about 6 to about 29, about 7 to about 28, about 8 to about 27, about 9 to about 26, about 10 to about 25, about 11 to about 24, about 12 to about 23, about 13 to about 22, about 14 to about 21, about 15 to about 20, about 16 to about 19, about 17, or about 18 amino acids in length.
[0030] The antigen-binding molecule can bind to an Fc receptor. For example, the antigen-binding molecule can comprise an Fc (fragment crystallizable) region. Fc regions are known in the art. The Fc region is the tail region of an antibody that interacts with Fc receptors and several proteins of the complement system. This property allows the antibody to activate the immune system. The Fc region comprises at least two heavy chain constant (CH) domains. Specifically, in an Fc domain derived from an IgG, IgA, or IgD antibody, the Fc region comprises the CH2 and CH3 domains of the antibody. In an Fc region derived from an IgM or IgE antibody, the Fc region comprises the CH2, CH3, and CH4 domains of the antibody. The Fc region can be a modified Fc region. For example, the Fc region can be an Fc region modified to optimize its ability to bind to FcR. Such optimization is known in the art and is described, for example, in (i) Mossner E et al., Increasing the efficacy of CD20 antibody therapy through the engineering of a new type II anti-CD20 antibody with enhanced direct and immune effector cell-mediated B-cell cytotoxicity. Blood. 2010;115(22):4393-4402; and (ii) Wang et al., 2018, IgG Fc engineering to modulate antibody effector functions. Protein Cell. 2018 January;9(1):63-73. doi:10.1007 / s13238-017-0473-8 (references contained therein).
[0031] An antigen-binding molecule may be capable of binding to an Fc receptor via a region other than the Fc region. That is, an antigen-binding molecule does not need to contain an Fc region to be able to bind to an Fc receptor. For example, an antigen-binding molecule may contain an antigen-binding region capable of binding to an Fc receptor (e.g., scFv, Fab, modified Fab, Fab', modified Fab', F(ab')2, Fv, dAb, Fd, dsFv, ds-scFv, scFv2, bispecific T cell engager, nanobody, DARPin, antibody mimetic, diabody, triabody, tetrabody, or polypeptide ligand of a receptor expressed on the surface of a cell targeted by an immune cell). An antigen-binding molecule may contain an antigen-binding region capable of binding to an Fc receptor and an antigen-binding region capable of binding to a different antigen, for example, an antigen expressed in the tumor microenvironment. For example, an antigen-binding molecule may contain an scFv capable of binding to an Fc receptor and an scFv capable of binding to a different antigen, for example, an antigen expressed in the tumor microenvironment. The antigen binding molecule can comprise a bispecific T cell engager comprising an scFv capable of binding to CD3 and an scFv capable of binding to a different antigen, for example, an antigen expressed in the tumor microenvironment.
[0032] The antigen-binding molecule may comprise an antigen-binding region and an Fc region. The antigen-binding molecule may be an antibody, scFv-Fc, dAb-Fc, or heavy-chain antibody. Exemplary heavy-chain antibodies include IgNAR and camelid antibodies. The antibody may comprise, for example, (a) a light chain encoded by SEQ ID NO: 18, (b) a heavy chain encoded by SEQ ID NO: 20, and / or (c) a truncated sequence encoded by SEQ ID NO: 19. The antibody molecule may comprise, for example, (a); (b); (c); (a) and (b); (a) and (c); (b) and (c); or (a), (b) and (c). The antibody may be encoded by SEQ ID NO: 17. The light chain encoded by SEQ ID NO: 18 may comprise a V chain encoded by SEQ ID NO: 5. L The heavy chain encoded by SEQ ID NO:20 comprises the VH Includes.
[0033] Preferably, the antigen-binding molecule is an scFv-Fc. An scFv-Fc is a fusion protein comprising an scFv fused to an Fc region. The structures of scFvs and Fc regions are known in the art and are described above. According to these structures, an scFv-Fc is a fusion protein comprising a V H and V L scFv-Fc can comprise a V domain, a CH2 domain, and a CH3 domain, which together form the Fc region. H and V L The scFv may comprise a V domain (together forming an scFv), and a CH2 domain, a CH3 domain, and a CH4 domain (together forming an Fc region). In an scFv-Fc, the scFv is linked to the Fc region. Preferably, the V domain in the scFv L or V H is linked to CH2 in the Fc region to link the scFv to the Fc region. The scFv can be linked directly to the Fc region, i.e., without a linker. The scFv can be linked to the Fc region via a linker. The linker can be (Ser(Gly)4), (Ser(Gly)4)2, (Ser(Gly)4)3, (Ser(Gly)4)4, or (Ser(Gly)4)5. The linker can be an amino acid consisting of about two amino acids or a short oligopeptide. The linker can form a hinge region. The scFv-Fc can be a bivalent scFv-Fc. A bivalent scFv-Fc contains two different scFvs, each linked to an Fc region. Essentially, a bivalent scFv-Fc contains two arms, each containing an scFv linked to an Fc region. scFvs, Fc regions, and linkages have been discussed above. The two arms are preferably linked. The link between the two arms preferably connects the linker between the scFv region and the Fc region in one arm to the linker between the scFv region and the Fc region in the other arm. The two arms are preferably connected at a point between the scFv and Fc regions in each arm.
[0034] Antigen-binding molecules can function to increase the cytotoxicity of target cells. That is, antigen-binding molecules can increase the killing of cells expressing the cognate antigen of the antigen-binding region. For example, antigen-binding molecules can increase the killing of tumor cells, endothelial cells, and / or immune cells. Increased killing can be mediated by engineered immune cells (i.e., immune cells containing a nucleic acid sequence encoding the antigen-binding molecule). Increased killing can be mediated by non-engineered ("bystander") immune cells (i.e., immune cells not containing a nucleic acid sequence encoding the antigen-binding molecule). Increased killing can be mediated by both engineered and non-engineered immune cells. Increased killing can be by any mechanism known in the art. Preferably, increased killing is mediated by increased ADCC. Increased killing can be mediated by increased engagement of AB T cells.
[0035] The antigen-binding molecule is preferably an opsonin. An opsonin is a molecule that binds to an antigen and enhances phagocytosis. Binding of an opsonin to an antigen promotes the interaction of the antigen with a cell surface receptor on an immune cell, thereby promoting the dynamics of phagocytosis. Therefore, an antigen-binding molecule can enhance phagocytosis. In particular, an antigen-binding molecule can enhance the phagocytosis of an antigen for which the antigen-binding region is specific. In other words, an antigen-binding molecule can enhance the phagocytosis of an antigen bound to the antigen-binding region (and therefore the antigen-binding molecule).
[0036] The antigen-binding region (and antigen-binding molecule) may be capable of binding to any antigen. That is, any antigen can be bound to the antigen-binding region (and antigen-binding molecule). Preferably, the antigen-binding region (and antigen-binding molecule) can bind to an antigen expressed on or by cells in the tumor microenvironment. An antigen is expressed in the tumor microenvironment if it is expressed by any type of cell present in the tumor microenvironment. For example, the antigen may be expressed by tumor cells, endothelial cells, or immune cells in the tumor microenvironment.

[0047] The antigen-binding molecule is preferably expressed by immune cells containing a nucleic acid sequence encoding the antigen-binding molecule. The expression of the antigen-binding molecule can be determined based on the presence of mRNA encoding the antigen-binding molecule in the immune cells.

[0048] How to generate immune cells The present invention provides a method for producing immune cells of the present invention. The method comprises introducing a nucleic acid sequence encoding an antigen-binding molecule into immune cells. Antigen-binding molecules are described in detail above. The nucleic acid sequence can be introduced into immune cells, for example, by transduction or transfection. For example, gdT cells can be transduced with the nucleic acid sequence using T cell transduction methods known in the art. Prior to such transduction, gdT cells can be expanded, for example, by culturing them in the presence of IL-2 and zoledronic acid for about 5 days (e.g., about 3 days, about 4 days, about 6 days, or about 7 days).
[0049] The term "transduction" can be used to describe viral-mediated nucleic acid transfer. Viral vectors can be used to transduce cells with nucleic acid sequences. Thus, the nucleic acid sequence can be contained in a viral vector. The viral vector can be a retroviral, lentiviral, adenoviral, adeno-associated (AAV) or herpes simplex virus (HSV) vector. Preferably, the viral vector is a retroviral vector. Methods for producing and purifying such vectors are known in the art. Immune cells can be transduced using any method known in the art. Transduction can be in vitro or ex vivo.
[0050] The term "transfection" can be used to describe non-viral-mediated nucleic acid transfer. Immune cells can be transfected using any method known in the art. Transfection can be in vitro or ex vivo. Any vector capable of transfecting immune cells can be used, such as conventional plasmid DNA or RNA transfection. Human artificial chromosomes and / or naked RNA and / or siRNA can be used to transfect cells with nucleic acid sequences. Human artificial chromosomes are described, for example, in Mol. Ther. 19(9):1591-1601 (2011) and Kouprina et al., Expert Opinion on Drug Delivery 11(4):517-535 (2014). Alternative non-viral delivery systems include DNA plasmids, naked nucleic acids, and nucleic acids complexed with delivery vehicles, such as liposomes. Non-viral methods for nucleic acid delivery include lipofection, microinjection, biolistics, virosomes, liposomes, immunoliposomes, polycation or lipid:nucleic acid conjugates, naked DNA, artificial virions, and drug-enhanced uptake of DNA. Lipofection is described, for example, in U.S. Patent Nos. 5,049,386, 4,946,787, and 4,897,355, and lipofection reagents are commercially available (e.g., Transfectam™ and Lipofectin™). Cationic and neutral lipids suitable for efficient receptor-recognition lipofection of polynucleotides include those described in Felgner, WO91 / 17424; WO91 / 16024.The preparation of targeted liposomes, e.g., lipid:nucleic acid complexes, including immunolipid complexes, is well known to those of skill in the art (e.g., Crystal Science 270:404-410 (1995); Blaese et al., Cancer Gene Ther. 2:291-297 (1995); Behr et al., Bioconjugate Chem. 5:382-389 (1994); Remy et al., Bioconjugate Chem. 5:647-654 (1994); Gao et al., Gene Therapy 2:710-722 (1995); Ahmad et al., Cancer Res. 52:4817-4820 (1992); U.S. Patent Nos. 4,186,183, 4,217,344, 4,235,871, 4,261,975, 4,485,054, 4,501,728, 4,774,085, 4,837,028, and 4,946,787).
[0051] Cells can be transfected with nucleic acid sequences or nucleic acid constructs using nanoparticle delivery systems, including but not limited to lipid-based systems, liposomes, micelles, microvesicles, and exosomes. For nanoparticles capable of delivering RNA, see, e.g., Alabi et al., Proc Natl Acad Sci U S A. 2013 Aug. 6; 110(32):12881-6; Zhang et al., Adv Mater. 2013 Sep. 6; 25(33):4641-5; Jiang et al., Nano Lett. 2013 Mar. 13; 13(3):1059-64; Karagiannis et al., ACS Nano. 2012 Oct. 23; 6(10):8484-7; Whitehead et al., ACS Nano. 2012 Aug. 28; 6(8):6922-9; and Lee et al., Nat Nanotechnol. 2012 Jun. 3; 7(6):389-93. Lipid nanoparticles, spherical nucleic acid (SNA™) constructs, nanoplexes and other nanoparticles (particularly gold nanoparticles) are also contemplated in the present invention as delivery vehicles for constructs or vectors.
[0052] Uptake of nucleic acid constructs can be enhanced by several known transfection techniques, such as those involving the use of transfection agents. Examples of these agents include cationic agents, such as calcium phosphate and DEAE-dextran, and lipofectants, such as lipofectamine, fugene, and transfectam.
[0053] Immune cells can be transfected under appropriate conditions. Immune cells can be contacted with the drug or vector for, for example, 5 minutes to 10 days, preferably 1 hour to 5 days, more preferably 5 hours to 2 days, and even more preferably 12 hours to 1 day.
[0054] The nucleic acid sequence transduced or transfected into immune cells induces expression of the antigen-binding molecule in the immune cells. The nucleic acid sequence preferably comprises a promoter operably linked to the sequence encoding the antigen-binding molecule. The promoter may be constitutively active in immune cells, or may be inducible in immune cells.

[0062] Immune cells can be formulated for administration using any suitable method. Formulation of cells using standard pharmaceutically acceptable carriers and / or excipients can be carried out using conventional methods in the pharmaceutical field. The exact nature of the formulation depends on several factors, including the cells to be administered and the desired route of administration.

[0063] The immune cells can be formulated with a physiologically acceptable carrier or diluent. Typically, such a formulation is prepared as a liquid suspension of cells. The cells can be mixed with an excipient that is pharmaceutically acceptable and compatible with the active ingredient. Suitable excipients include, for example, water, saline, dextrose, glycerol, etc., and combinations thereof.

[0067] [Example] Vδ2 + γδ T cells can be transduced to secrete proteins that specifically bind to antigens on target cells Vδ2 + γδ T cells were transduced to secrete scFv fusion peptides targeting the tumor-associated antigens CEA and GD2. Supernatants from transduced cells were collected and analyzed for CEA. + CAPAN-1 cells and CEA-HELA cells, or GD2 + / - The scFv-Fc fusion protein was applied to SupT1 cells. Binding of the scFv-Fc fusion protein was detected using a phycoerythrin-conjugated anti-human Fc antibody. Purified anti-CEA scFv-Fc fusion protein produced in the cell line or purified anti-GD2 antibody was used as a positive control.
[0068] As shown in Figure 2, components of the supernatants from the transduced cell lines and transduced V52 γδ T cells were able to specifically bind to antigen-positive cells, resulting in the detection of human Fc on their surface.
[0069] Cytotoxicity experiments showing the effect of direct and indirect contact with Vδ2 secreting scFv-Fc proteins Because engineered T cells secrete proteins that can affect the cytotoxicity of bystander, unengineered cells, a series of experimental conditions were developed to demonstrate this. The experimental setup is shown in Figure 3. Briefly, in addition to comparing the cytotoxicity of transduced and untransduced V52 when directly cocultured with target cells, two additional conditions were used to demonstrate cell-contact-autonomous effects. First, supernatant from transduced V52 was added to cocultures of untransduced V52 and target cells. Second, untransduced cells were cocultured with targets in the presence of transduced cells sequestered behind a semipermeable membrane that blocks cell passage but not secreted molecules. All cocultures were for 18 hours, with an effector:target ratio of 1:1. To demonstrate the effect of anti-CEA scFv-Fc fusion proteins, CEA+CAPAN-1 and CEA-HELA cells were used. To demonstrate the effect of the anti-GD2 scFv-Fc fusion protein, GD2 or isogenic GD2 -SupT1 engineered to express wild-type SupT1 was used.
[0070] Vδ2 cells transduced to secrete anti-CEA scFv-Fc fusion proteins showed increased CEA expression compared to NT Vδ2s + V52 transduced to express anti-CEA scFv-Fc fusion protein resulted in significantly higher target mortality (p<0.0001, Figure 4A). + Supernatants from cells express CEA by non-transduced Vδ2 + Enhanced target killing (p<0.0001) and CEA - It also slightly increased target killing (p=0.031, Figure 4B). When V52 secreting anti-CEA scFv-Fc fusion proteins were sequestered behind a semipermeable membrane, the non-transduced V52 secreted CEA compared to the isolation of non-transduced cells. + It was also able to enhance the ability to kill the target (p=0.012, Figure 4C).
[0071] Similar data were observed for V52 transduced to secrete an anti-GD2 scFv-Fc fusion protein. Transduced V52 showed better GD2 secretion than non-transduced ones (p=0.03). + Kills the target and produces the same GD2 - Greater GD2 than controls + The supernatant from the anti-GD2-scFv-Fc fusion protein expressing Vδ2 showed cytotoxicity against the target (p=0.0049, Figure 4D). The supernatant from the anti-GD2-scFv-Fc fusion protein expressing Vδ2 showed cytotoxicity against the target (p=0.0049, Figure 4D). - GD2 of non-transduced Vδ2 when compared to targets (p=0.0002, Figure 4E) + Sequestration of V52 secreting anti-GD2 scFv-Fc fusion proteins behind a semipermeable membrane significantly enhanced their ability to kill targets compared with sequestration of non-transduced cells (p=0.0158) or GD2 - Compared to target killing (p=0.0003, Figure 4F), non-transduced Vδ2 GD2 + It could also enhance its ability to kill targets.
[0072] CEA non-transduced Vδ2 ± When targets were co-cultured in the presence of V52 secreting anti-CEA scFv-Fc fusion protein sequestered behind a semipermeable membrane or untransduced controls, a significant increase in IFNγ production was observed only when cells secreting anti-CEA scFv-Fc fusion protein were sequestered (p=0.0014 compared to sequestered NT V52), suggesting that CEA + Targets were used (CEA - p = 0.012 compared to target, Figure 5).
[0073] Vδ2 + γδ T cells can be transduced to secrete whole antibodies that specifically bind to antigens on target cells. HEK293T and Vδ2 + γδ T cells were transduced to secrete IgG1 antibodies targeting the tumor-associated antigen GD2 (SEQ ID NO: 17). Supernatants from HEK293T cells transduced with reduced volumes of virus were collected and GD2 + / - The transduced V52 cells were applied to the scFv-Fc fusion protein. Binding of the scFv-Fc fusion protein was detected using a phycoerythrin-conjugated anti-human Fc antibody (Figure 6). + Supernatants from γδT cells were also collected and analyzed using GD2 + / - SupT1 cells and antibody binding was detected using an anti-human IgG antibody conjugated with AlexaFluor 647 (Figure 7). Purified anti-GD2 antibody produced in a cell line was used as a positive control.
[0074] As shown in Figures 6 and 7, the transduced cell lines and transduced V52 + Components of the γδ T cell-derived supernatant were able to specifically bind to antigen-positive cells, resulting in the detection of human Fc or IgG on their surface.
[0075] Cytotoxicity experiments demonstrating the effects of direct and indirect contact with antibody-secreting Vδ2 To demonstrate cell contact-dependent and cell contact-autonomous effects, two experimental systems were used (Figure 8A). Briefly, untransduced Vδ2 + γδ T cells or Vδ2+ γδ T cells transduced to express anti-GD2 IgG1 were used as GD2 + / - In a second experiment, untransduced Vδ2 cells were co-cultured with SupT1 at a 1:1 effector:target ratio. + Supernatants from γδ T cells or Vδ2+ γδ T cells transduced to express anti-GD2 IgG1 were used to treat non-transduced Vδ2+ γδ T cells and GD2 + / - V52 cells transduced to express anti-GD2 IgG1 were added to a 1:1 co-culture of V52 cells transduced to express anti-GD2 IgG1. Target cell death was determined using flow cytometry, and Figures 8B and 8C show representative data from three replicates. + γδ T cells exhibited enhanced cytotoxicity against SupT1-GD2 but not against SupT1-wt (Fig. 8B). Vδ2 transduced to express anti-GD2 IgG1 + Supernatants from γδ T cells express untransduced Vδ2 against SupT1-GD2 + It enhanced the cytotoxicity of γδT cells against SupT1-wt but not against SupT1-wt ( Fig. 8C ).
[0076] Materials and Methods cell line CAPAN-1, HELA, and SupT1 cell lines were obtained from ATCC. SupT1-GD2 was generated by transducing wild-type SupT1 with a vector encoding GD2 / GD3 synthase and isolating clones of successfully transduced cells.
[0077] Donor selection for PBMCs PBMCs were isolated from the blood of healthy donors aged 20–36 years. Donors were screened for cross-reactivity between the SFP construct and expanded Vδ2 cells prior to inclusion. Donors with evidence of cross-reactivity were not included in the cytotoxicity studies.
[0078] Isolation of fresh PBMCs and pre-stimulation Twenty ml of whole blood was diluted with 10 ml of PBS plus 500 μl of 100 mM EDTA and layered on 20 ml of Percoll. Interface PBMCs (20 min, 300 × g, RT) were washed in PBS, resuspended in 25 ml of T cell medium (X-VIVO 15 (Lonza BioWhittaker, Maryland, USA)) supplemented with penicillin / streptomycin (100 IU / ml penicillin, 100 μg / ml streptomycin (Sigma-Aldrich, Missouri, USA)), and cultured overnight before use.
[0079] Vδ2 + T cell expansion Specific Vδ2 + For γδ T cell expansion, PBMCs were isolated as described above and cultured in RPMI-1640 medium supplemented with L-glutamine (2 mM, Sigma-Aldrich), penicillin / streptomycin (100 IU / ml penicillin, 100 μg / ml streptomycin (Sigma-Aldrich)), and 10% FCS (v / v, Gibco, Massachusetts, USA). + γδ T cell expansion was stimulated with 5 μM zoledronic acid (Actavis, New Jersey, USA) and 100 IU / ml IL-2 (Aldesleukin Novartis, Frimley, UK), which were added to the PBMC suspension after PBMC isolation (day 1). IL-2 was replenished every 2–3 days by removing half of the medium from the wells and replacing it with fresh medium containing 200 IU / ml IL-2.
[0080] Construction of retroviral constructs The gumma retroviral vector used in all constructs was SFG (Riviere et al., 1995), pseudotyped with the RD114 envelope. DNA fragments were amplified using Phusion HT II polymerase according to the manufacturer's instructions (Thermo Scientific, Massachusetts, USA). PCR was performed on a PTC-200 DNA Engine (MJ Research, Massachusetts, USA). PCR products were extracted from 1% agarose gels using a Wizard SV Gel & PCR Clean-Up Kit (Promega, Wisconsin, USA). Sample concentrations were determined using a NanoDrop ND-1000 spectrophotometer (Thermo Scientific, Massachusetts, USA). Constructs contain one of a series of scFvs against a panel of targets, including human GD2 (clone 14G2A) or human CEA (clone SM3EL), linked to the Fc portion of human IgG1.
[0081] In addition to the scFv-Fc fusion protein construct, we included a marker bearing the CD34 epitope, RQR8 (Philip et al., 2014), separated from the scFv-Fc fusion protein by a cleavable 2A peptide, which allows for the detection of cells expressing the scFv-Fc fusion protein by flow cytometry after staining with the anti-CD34 antibody clone QBend10.
[0082] Construction of lentiviral constructs The lentiviral vector used for all antibody transduction was pCCL (Dull et al., 1998), pseudotyped with the RDPro envelope (Cosset et al., 1995). DNA fragments were amplified using Phusion HT II polymerase according to the manufacturer's instructions (Thermo Scientific, Massachusetts, USA). PCR was performed on a PTC-200 DNA Engine (MJ Research, Massachusetts, USA). PCR products were extracted from 1% agarose gels using the Wizard SV Gel & PCR Cleanup Kit (Promega, Wisconsin, USA). Sample concentrations were determined using a NanoDrop ND-1000 spectrophotometer (Thermo Scientific, Massachusetts, USA). The construct contained an anti-GD2 IgG1 (clone 14G2A).
[0083] In addition to the IgG1 construct, eGFP was included, separated from the IgG1 protein by a cleavable 2A peptide, which allows for the detection of IgG1-expressing cells by flow cytometry.
[0084] Production of viral particles by transfection 1.5×10 6 293T cells / 100mm 2Dishes (Nucleon Delta Surface, Thermo Fisher Scientific) were seeded in 293T medium (D-MEM, 10% FCS (v / v)) on day 1. γ-Retroviral or lentiviral particles were generated by co-transfecting 293T cells on day 2 using Gene Juice transfection reagent (Novagen / Millipore, Massachusetts, USA) according to the manufacturer's instructions. The supernatant containing the viral particles was collected on day 4, medium was added, and the supernatant was collected on day 5. γ-Retroviral supernatants were pooled, filtered (0.45 μm filter, Millipore), and either used directly for transduction or stored overnight at 4°C before use. Lentiviral supernatants were concentrated by ultracentrifugation and frozen for later use.
[0085] Gamma retroviral transduction of T cells The viral supernatant was preloaded onto a 24-well plate coated with Retronectin (Takara Bio, Tokyo, Japan), and T cells were transduced using 0.5 × 10 cells suspended in 0.5 ml of T cell medium plus 400 IU of IL-2. 6 T cells were mixed with 1.5 ml viral supernatant and centrifuged at 1000 × g for 40 minutes at room temperature. Typically, 12 × 10 cells were collected per donor. 6 T cells were seeded for transduction.
[0086] γδ T cell expansion was stimulated with 5 μM zoledronic acid (Actavis, New Jersey, USA) and 100 IU / ml IL-2 (Aldesleukin) and transduction was performed on day 5. On day 8 of culture (day 3 post-transduction), cells were pooled, washed, and cultured at 2 × 10 cells in T cell medium + 100 IU IL-2 / ml (24-well plate, Nucleon Delta Surface, Thermo Scientific, Massachusetts, USA). 6 Cells were seeded at 1000 x g / ml. Transduction efficiency was determined by flow cytometry on day 10 (day 5 post-transduction).
[0087] Lentiviral transduction of T cells T cell transduction was performed in 96-well plates, with each well containing 0.3 x 10 cells suspended in 0.3 ml of T cell medium. 6 Concentrated lentivirus containing T cells was added and the plates were centrifuged for 40 minutes at 1000 x g at room temperature.
[0088] Expansion of γδ T cells was stimulated with 5 μM zoledronic acid (Actavis, New Jersey, USA) and 100 IU / ml IL-2 (Aldesleukin), and transduction was performed on day 2. On day 5 of culture (day 3 post-transduction), cells were pooled, washed, and transduced into 1 × 10 cells in T cell medium + 100 IU IL-2 / ml. 6 cells / cm 2 Transduction efficiency was determined by flow cytometry on day 7 (day 5 post-transduction).
[0089] Cytotoxicity assay Target cell lines were labeled with CellTrace Violet (Thermo Fisher) and then co-cultured with effector cells at an effector:target ratio of 1:1 in either RPMI1640 + 10% FCS + 1% Pen / Step + 1% L-glutamine supplemented with 100 μg / ml IL-2, or supernatant from V52 cells secreting scFv-Fc fusion proteins cultured in the same medium.
[0090] For assays involving effector cells sequestered behind a semipermeable membrane, cells were separated using 0.4 μm pore size TransWells (Thermo Fisher). Equal numbers of effectors were placed in the transwells and main wells. Target cells were placed in the main wells, and a 1:1 effector:target ratio was calculated for cells in the main well.
[0091] After 18 hours of co-culture, cells were harvested and analyzed by flow cytometry. Cell death was identified by staining with Ghost Red fixable viability dye (Tonbo Biosciences, San Diego, CA) on violet-labeled cells.
