Abstract
Description
Background of the Invention
[0002] Immunotherapy based on tumor-specific T cells has been investigated, including the use of engineered T cells for anti-tumor treatment. Chimeric antigen receptors (CARs) consist of an extracellular tumor recognition / targeting domain, an extracellular linker / spacer, a transmembrane domain, and an intracellular T cell activation and co-stimulatory signaling domain. The design of the recognition / targeting domain is crucial to avoiding undesirable off-target effects. Most CAR tumor-targeting domains are single-chain variable fragments (scFvs) derived from antibody sequences, utilizing the specificity of antibody binding to specific antigens. There are also examples of CAR tumor-targeting domains derived from normal receptor ligands, such as IL-13 cytokine CARs that target cells expressing the IL-13 receptor IL-13Rα2. Despite some significant successes, identifying and validating novel CAR tumor-targeting domains remains a major challenge in this field.
[0003] Malignant gliomas (MG), including glioblastoma multiforme (AA-WHO grade III) and glioblastoma glioblastoma (GBM-WHO grade IV), have an incidence of approximately 20,000 new cases diagnosed annually in the United States. According to the American Brain Tumor Association, based on data from the 2010 U.S. Census, the overall prevalence of MG among surviving individuals is roughly 140,000. Although MG is a rare disease, it is highly aggressive and heterogeneous in its malignant behavior and is almost always fatal. Current standard of care for advanced MG provides only short-term benefit, and these brain tumors are, in fact, incurable. Indeed, even with modern surgical and radiation therapy techniques (which often exacerbate an already severe morbidity imposed by targeting the central nervous system (CNS), 5-year survival rates are very low. Furthermore, for the majority of patients with recurrent disease, there are very few treatment options. Therefore, there is a clear need for more effective treatments, especially for those patients who have relapsed / progressed after first-line therapy.
[0004] Adoptive T-cell therapy (ACT) using engineered T cells expressing chimeric antigen receptors (CARs) can provide a safe and effective way to reduce the relapse rate of mycoplasma leukemia (MG) because CAR T cells can be engineered to specifically recognize antigenically unique tumor populations (Cartellieri et al. 2010 J Biomed Biotechnol 2010:956304; Ahmed et al. 2010 Clin Cancer Res 16:474; Sampson et al. 2014 Clin Cancer Res 20:972; Brown et al. 2013 Clin Cancer Res 2012 18:2199; Chow et al. 2013 Mol Ther 21:629), and T cells can migrate through the brain parenchyma to target and kill invasive malignant cells (Hong et al. 2010 Clin Cancer Res 16:4892; Brown et al. 2007 J Immunol 179:3332; Hong et al. 2007 J Immunol 179:3332; Hong et al. 2010 Clin Cancer Res 16:4892; Brown ... Hong et al. 2010 J Immunol etal.2010 Clin Cancer Res16:4892; Yaghoubi 2009 Nat Clin Pract Oncol 6:53). Invention Overview
[0006] This article describes a chimeric transmembrane immune receptor (chimeric antigen receptor, or "CAR") comprising an extracellular domain, a transmembrane region, and an intracellular signaling domain. The extracellular domain comprises chlorhexidine (a 36-amino acid peptide toxin found in the venom of the scorpion *Leiurus quinquestriatus*) or a related toxin, or a variant of chlorhexidine or a related toxin, and optionally a spacer region containing, for example, a portion of the human Fc domain. The transmembrane portion comprises, for example, a CD4 transmembrane domain, a CD8 transmembrane domain, a CD28 transmembrane domain, or a CD3 transmembrane domain. The intracellular signaling domain comprises a signaling domain derived from the ζ chain (CD3ζ) of the human CD3 complex and one or more co-stimulatory domains, such as a 4-1BB co-stimulatory domain. When expressed on the surface of T cells, the extracellular domain enables the CAR to direct T cell activity to cells expressing the chlorhexidine receptor. Such cells include glioblastoma cells. The intracellular region contains a co-stimulatory domain tandem with CD3ζ, such as the 4-1BB (CD137) co-stimulatory domain, enabling T cells to receive co-stimulatory signals. T cells can be engineered, for example, with patient-specific autologous T cells to express the CAR described herein, and engineered cells can be expanded for use in ACT. Various T cell subsets can be used, including both αβ T cells and γδ T cells. Additionally, the CAR can be expressed in other immune cells, such as NK cells. In cases where patients are treated with immune cells expressing the CAR described herein, the cells can be autologous T cells or allogeneic T cells. In some cases, the cells used include CD4+ and CD8+ central memory T cells (T cells). CM Both cell populations consist of CD62L+, CCR7+, CD45RO+, and CD45RA-, or the cells used include CD4+ and CD8+ T cells. CM Cells, stem cells, central memory T cells, and naive T cells (i.e., T cells) CM / SCM / N (Cell population). T CM / SCM / N The cell population consisted of CD62L+, CCR7+, and included both CD45RA+ and CD45RO+ cells, as well as both CD4+ and CD8+ cells. The use of these cells improved long-term cell persistence after adoptive transfer compared to other types of patient-specific T cells.

Table 1 below provides several spacers that may be used in the CAR described herein.
[0024] Table 1: Examples of spacers
[0025]
[0026]
[0027]
[0028] Some spacer regions comprise whole or part of an immunoglobulin (e.g., IgG1, IgG2, IgG3, IgG4) hinge region, i.e., a sequence falling between the CH1 and CH2 domains of an immunoglobulin, such as the IgG4 Fc hinge or the CD8 hinge. Some spacer regions contain the immunoglobulin CH3 domain or both the CH3 and CH2 domains. Immunoglobulin-derived sequences may contain one or more amino acid modifications, such as 1, 2, 3, 4, or 5 substitutions, for example, substitutions that reduce off-target binding.
[0029] "Amino acid modification" refers to the substitution, insertion, and / or deletion of amino acids in a protein or peptide sequence. "Amino acid substitution" or "replacement" refers to the replacement of an amino acid at a specific position in a parent peptide or protein sequence with another amino acid. Substitution can be performed to change the amino acids in the resulting protein in a non-conservative manner (i.e., by changing the codon belonging to an amino acid group of a specific size or characteristic to an amino acid belonging to another group) or a conserved manner (i.e., by changing the codon belonging to an amino acid group of a specific size or characteristic to an amino acid belonging to the same group). This conserved change generally results in minimal alteration to the structure and function of the resulting protein. Here are examples of several groups of amino acids: 1) Amino acids with nonpolar R groups: alanine, valine, leucine, isoleucine, proline, phenylalanine, tryptophan, methionine; 2) Amino acids with uncharged polar R groups: glycine, serine, threonine, cysteine, tyrosine, asparagine, glutamine; 3) Amino acids with charged polar R groups (negatively charged at pH 6.0): aspartic acid, glutamic acid; 4) Basic amino acids (positively charged at pH 6.0): lysine, arginine, histidine (at pH 6.0).

[0072] Figure 25The sequence of chloramphenicol (SEQ ID NO:1) was described. Invention Details
[0074] The following describes the structure, construction, and characterization of several chimeric antigen receptors containing chloramphenicol (CLTX). Chimeric antigen receptors (CARs) are recombinant biomolecules containing at least an extracellular recognition domain, a transmembrane region, and an intracellular signaling domain. Therefore, the term "antigen" is not limited to molecules that bind antibodies, but also refers to any molecule that can specifically bind a target. For example, a CAR may include a ligand that specifically binds to a cell surface receptor. The extracellular recognition domain (also called the extracellular domain or simply by the recognition element it contains) contains a recognition element that specifically binds to molecules present on the cell surface of the target cell. The transmembrane region anchors the CAR to the membrane. The intracellular signaling domain contains a signaling domain derived from the zeta chain of the human CD3 complex and optionally includes one or more co-stimulatory signaling domains. In an MHC-independent manner, CARs can both bind antigens and induce T cell activation. Therefore, CARs are "universal" immune receptors that can treat patient populations with antigen-positive tumors, regardless of their HLA genotype. Adoptive immunotherapy using T lymphocytes expressing tumor-specific CARs can be a powerful therapeutic strategy for treating cancer.
[0075] The CAR containing chloramphenicol described in this article is called CLTX-IgG4(EQ)-CD28gg-Zeta. This CAR includes several important features, including: chloramphenicol; IgG4 Fc region mutated at two sites in the CH2 region (L235E; N297Q) in a manner that reduces Fc receptor (FcR) binding; CD28 co-stimulatory domain; and CD3ζ activation domain.
[0076] In some cases, a vector can be used to generate the CAR described herein, wherein the CAR open reading frame is followed by a T2A ribosomal skipping sequence and a truncated CD19 (CD19t) lacking the cytoplasmic signaling tail (truncated at amino acid 323). In this arrangement, co-expression of CD19t provides an inert, non-immunogenic surface marker that allows for precise assay of genetically modified cells and enables positive selection of genetically modified cells, as well as efficient cell transport and / or in vivo therapeutic T-cell imaging following adoptive transfer. Co-expression of CD19t provides a marker for the selective deletion of therapeutic cells by immunotargeting transduction of cells in vivo using clinically available antibodies and / or immunotoxins, thereby functioning as a suicide switch.
[0077] The CAR described herein can be generated by any means known in the art, although recombinant DNA technology is preferred. Nucleic acids encoding several regions of the chimeric receptor can be prepared and assembled into a complete coding sequence using standard molecular cloning techniques known in the art (genomic library screening, PCR, primer-assisted ligation, site-directed mutagenesis, etc.). The resulting coding regions are preferably inserted into an expression vector and used to transform a suitable expression host cell line, preferably a T lymphocyte cell line, and most preferably selected from in vivo T lymphocyte cell lines.
[0078] Multiple T cell subsets isolated from patients can be transduced using vectors for CAR expression, including unselected PBMCs or enriched CD3 T cells or enriched CD3 or memory T cell subsets or T cells. CM or T CM / SCM / N Central memory T cells are a useful subset of T cells. They can be utilized by, for example... The device uses immunomagnetic selection to enrich CD45RO+ / CD62L+ cells expressing the desired receptor to isolate central memory T cells from peripheral blood mononuclear cells (PBMCs). Cells enriched for central memory T cells can be activated using anti-CD3 / CD28 and transduced using a SIN lentiviral vector, for example, that directs CAR expression as well as truncated human CD19 (CD19t), a non-immunogenic surface marker for both in vivo detection and possible in vitro selection. Activated / genetically modified central memory T cells can be expanded in vitro using IL-2 / IL-15 and then cryopreserved. Example
[0079] Example 1: Construction and structure of CLTX-IgG4Fc(EQ)-CD28-zeta CAR
[0080] The structure of a useful CAR containing chlortoxin, CLTX-IgG4Fc(EQ)-CD28-zeta, is described below. The codon-optimized CAR sequence comprises: chlortoxin, an IgG4 Fc spacer containing mutations (S228P, L235E) that significantly reduce Fc receptor-mediated recognition, a CD28 transmembrane domain, a co-stimulatory CD28 cytoplasmic signaling domain, and a CD3ζ cytoplasmic signaling domain. A T2A ribosomal skipping sequence separates this CAR sequence from the inert, non-immunogenic cell surface detection / selection marker CD19t. This T2A linkage results in the coordinated expression of both the CAR and CD19t from a single transcript. Figure 1A is a schematic diagram of the open reading frame of CLRX-IgG4Fc(EQ)-CD28-zeta-T2ACD19t. The diagram indicates the CLRX-IgG4Fc(EQ)-CD28-zetaCAR and the T2A ribosomal skipping and truncated CD19 sequence. Expression of the CAR and CD19t cassette is driven by the human EF1 promoter (EF1p). Figure 1 B schematically depicts the mature CAR expression.
[0081] The CLTX-IgG4Fc(EQ)-CD28-zeta sequence was generated by fusing the human GM-CSF receptor α leader peptide chlorotoxin, the S228P / L235E / N297Q modified IgG4Fc hinge (where the double mutation L235E / N297Q interferes with FcR recognition), the CD28 transmembrane domain, the CD28 cytoplasmic signaling domain, and the CD3ζ cytoplasmic signaling domain sequence. This sequence was synthesized de novo after codon optimization. The T2A sequence was obtained by digesting plasmids containing T2A. The CD19t sequence was obtained by transmembrane component (i.e., base pairs 1-972) sequence from the leader peptide sequence of plasmids containing CD19. All three fragments, 1) CLTX-IgG4Fc(EQ)-CD28-zeta, 2) T2A, and 3) CD19t, were cloned into the multiple cloning site of the epHIV7 lentiviral vector. When transfected into suitable cells, the vector integrated into the host cell genome. Figure 9 The amino acid sequence of CLTX-IgG4Fc(EQ)-CD28-zeta was presented, indicating multiple domains.
[0082] Example 2: Construction and structure of epHIV7 for expressing CLTX-IgG4Fc(EQ)-CD28-zeta
[0083] The pHIV7 plasmid is a parent plasmid from which the clinical plasmid CLTX-IgG4Fc(EQ)-CD28-zeta-T2A-CD19t_epHIV7 was derived at the T cell Therapeutics Research Laboratory (TCTRL) in City of Hope (COH). The epHIV7 vector for CAR expression was generated from the pHIV7 vector. Importantly, this vector uses the human EF1 promoter to drive CAR expression. Both the 5' and 3' sequences of the vector are derived from pv653RSN, as previously derived from the HXBc2 provirus. The polypurine fragment DNA flap sequence (cPPT) is derived from the HIV-1 strain pNL4-3 in the NIH Reagent Repository for AIDS. The prairie dog posttranscriptional regulatory element (WPRE) sequence has been previously described.
[0084] pHIV7 was constructed as follows. In short, the pv653RSN containing a 653bp sequence from gag-pol, plus 5' and 3' long terminal repeats (LTRs) and the intermediate SL3-neomycin phosphotransferase gene (Neo), was subcloned into pBluescript: In step 1, p5'HIV-1 51 was prepared from the sequence from the 5'LTR to the rev-response element (RRE), then the 5'LTR was modified by removing the sequence upstream of the TATA box and first ligated to the CMV enhancer, then ligated to the SV40 origin of replication (p5'HIV-2). In step 2, after cloning the 3'LTR into pBluescript to prepare p3'HIV-1, a 400-bp deletion was performed in the 3'LTR enhancer / promoter to remove the cis-regulatory element in HIV U3 and form p3'HIV-2. In step 3, fragments isolated from p5'HIV-3 and p3'HIV-2 were ligated to prepare pHIV-3. In step 4, p3'HIV-2 was further modified by removing additional upstream HIV sequences to generate p3'HIV-3, and a 600-bp BamHI-SalI fragment containing WPRE was added to p3'HIV-3 to prepare p3'HIV-4. In step 5, the size of the pHIV-3 RRE was reduced by PCR and ligated to the 5' fragment (not shown) from pHIV-3 and ligated to p3'HIV-4 to prepare pHIV-6. In step 6, a 190-bp BglII-BamHI fragment containing a cPPT DNA flap sequence from HIV-1 pNL4-3 (55) was amplified from pNL4-3 and placed between the RRE and WPRE sequences in pHIV-6 to prepare pHIV-7. This parental plasmid pHIV7-GFP (GFP, green fluorescent protein) was used to package the parental vector using a four-plasmid system.
[0085] The packaging signal psi(ψ) is required for the efficient packaging of the viral genome into the vector. RRE and WPRE enhance RNA transcript transport and transgene expression. Valve sequences combined with WPRE have been shown to enhance the transduction efficiency of lentiviral vectors in mammalian cells.
[0086] The auxiliary functions required for generating the viral vector were divided into three separate plasmids to reduce the likelihood of generating replicative lentiviruses via recombination: 1) pCgp encodes the gag / pol protein required for viral vector assembly; 2) pCMV-Rev2 encodes the Rev protein, which acts on the RRE sequence to help transport the viral genome for efficient packaging; and 3) pCMV-G encodes the glycoprotein of vesicular stomatitis virus (VSV), which is required for the infectivity of the viral vector.
[0087] Minimal DNA sequence homology exists between the pHIV7-encoded vector genome and the helper plasmid. Homologous regions include a packaging signal region of approximately 600 nucleotides located in the gag / pol sequence of the pCgp helper plasmid; the CMV promoter sequences in all three helper plasmids; and the RRE sequence in the pCgp helper plasmid. It is highly unlikely that replicative recombinant viruses could be generated due to homology in these regions, as this would require multiple recombination events. Furthermore, any resulting recombinants would lack the functional LTR and tat sequences required for lentiviral replication.
[0088] The CMV promoter was replaced by the EF1α-HTLV promoter (EF1p), and the new plasmid was named epHIV7. EF1p has a length of 563 bp and was introduced into epHIV7 using NruI and NheI after the CMV promoter was removed.
[0089] The lentiviral genome has been removed from this system, excluding the gag / pol and rev, which are essential for the pathogenicity of the wild-type virus and for productive infection of target cells. Furthermore, the CLTX-IgG4Fc(EQ)-CD28-zeta-T2ACD19t_epHIV7 vector construct does not contain a complete 3' LTR promoter; therefore, the expressed and reverse-transcribed proviral DNA genome obtained in target cells will have an inactive LTR. Due to this design, no HIV-1-derived sequences will be transcribed from the provirus, and only therapeutic sequences will be expressed from their respective promoters. The removal of LTR promoter activity in the SIN vector will significantly reduce the likelihood of unintentional activation of the host gene.
[0090] Example 3: Generation of a vector for transducing patient T cells
[0091] Vectors for transducing patient T cells can be prepared as follows: For each plasmid (i.e., 1) a plasmid expressing CAR and optional markers such as truncated CD19; 2) pCgp; 3) pCMV-G; and 4) pCMV-Rev2), a seed library is generated, which is used to inoculate a fermenter to produce a sufficient quantity of plasmid DNA. The identity, sterility, and endotoxin content of the plasmid DNA are tested before use to generate lentiviral vectors.
[0092] In short, cells are expanded from 293T working cells (WCBs) that have been tested to confirm their identity and are free from viral contamination. A vial of 293T cells from the 293T WCBs is thawed. The cells are cultured and expanded until a sufficient number of cells are available for plating into an appropriate number of 10-layer cell factory (CF) plates for vector production and cell line maintenance. Single-cell lines can be used for production.
[0093] Lentiviral vectors are produced in sub-batches of up to 10 CFs. Two sub-batches can be produced within the same week, resulting in approximately 20 L of lentiviral supernatant per week. During downstream processing, material from all batches is combined to produce a single batch of product. 293T cells are seeded in CFs in 293T medium (DMEM containing 10% FBS). The plants are placed in a 37°C incubator and leveled to achieve uniform cell distribution across all layers of the CF. After two days, cells are transfected using the CaPO4 method with the four lentiviral plasmids described above, which involves a mixture of Tris:EDTA, 2M CaCl2, 2X HBS, and the four DNA plasmids. On day 3 post-transfection, the supernatant containing the secreted lentiviral vector is collected, purified, and concentrated. Cells are collected from each CF after removing the supernatant. Cells are digested with trypsin from each plant and collected by centrifugation. Cells are resuspended in freezing medium and cryopreserved. These cells are then used for replication-capable lentivirus (RCL) assays.
[0094] To purify and prepare the vector, the crude supernatant was clarified by membrane filtration to remove cell debris. Digestion with endonuclease was then performed. Degrade host cell DNA and residual plasmid DNA. Clarify cell debris in the viral supernatant using a 0.45 μm filter. Collect the clarified supernatant and add [a specific ingredient]. Pre-weighed containers (final concentration 50 U / mL) were used. Endonuclease digestion of residual plasmid DNA and host genomic DNA was performed at 37°C for 6 hours. Initial tangential flow ultrafiltration (TFF) concentration of the endonuclease-treated supernatant was used to remove residual low molecular weight components from the crude supernatant, while concentrating the virus approximately 20-fold. The clarified endonuclease-treated viral supernatant was circulated through a hollow fiber cartridge with 500 kD NMWCO at a flow rate designed to maintain a shear rate of approximately 4000 / s or lower while maximizing throughput. Perfiltration of the nuclease-treated supernatant was initiated during the concentration process to maintain cartridge performance. An 80% permeate replacement rate was established using 4% lactose in PBS as the perfiltration buffer. The viral supernatant was brought to the target volume, representing approximately 20-fold concentration of the crude supernatant, and further perfiltration was continued for 4 exchange volumes, where the permeate replacement rate was 100%.
[0095] Further concentration of the viral products was achieved using high-speed centrifugation. Individual sub-batches of lentivirus were precipitated using a Sorvall RC-26plus centrifuge at 6000 RPM (6,088 RCF) at 6°C for 16–20 hours. Viral pellets from each sub-batch were then reconstituted in 50 mL of PBS with 4% lactose. The reconstituted pellets in this buffer represent the final formulation of the viral preparation. The entire vector concentration process resulted in approximately a 200-fold volume reduction. After all sub-batches were completed, the material was placed at -80°C while the sterility of each sub-batch sample was tested. Once sterility was confirmed, the sub-batches were rapidly thawed with agitation at 37°C. The material was then pooled and manually aliquoted in a Class II A / B3 biosafety cabinet. 1 mL of concentrated lentivirus was packed into sterile USP Class 6, externally threaded O-ring cryovials.
[0096] To ensure the purity of the lentiviral vector preparation, it was tested for residual host DNA contamination and for the transfer of residual host and plasmid DNA. In other tests, the vector identity was assessed by RT-PCR to ensure the presence of the correct vector.
[0097] Example 4: Preparation of T cells suitable for ACT
[0098] If using T CM To express CAR, suitable patient cells can be prepared as follows: First, T lymphocytes are obtained from the patient via leukocyte ablation, and suitable allogeneic or autologous T cell subsets, such as central memory T cells (T cells), are genetically modified. CM The CAR is expressed and then administered back to the patient by any clinically acceptable means to achieve anti-cancer treatment.
[0099] Suitable T-shirt CM The following steps can be taken: Apheresis products obtained from consenting study participants are treated with Ficoll, washed, and incubated overnight. Then, GMP-grade anti-CD14, anti-CD25, and anti-CD45RA reagents (Miltenyi Biotec) and CliniMACS are used. TM The separation device depleted populations of monocytes, regulatory T cells, and naive T cells. After depletion, the cells were processed in CliniMACS. TM The isolation device used DREG56-Biotin (COH clinical grade) and anti-biotin microbeads (Miltenyi Biotec) to enrich CD62L+ T cells in the negative fraction. CM cell.
[0100] After enrichment, T was prepared in complete X-Vivo15 with 50 IU / mL IL-2 and 0.5 ng / mL IL-15. CM The cells were then transferred to Teflon cell culture bags, where they were cultured using Dynal ClinEx. TM Cells were stimulated with Vivo CD3 / CD28 beads. Five days post-stimulation, cells were transduced with a lentiviral vector expressing the desired CAR at a multiplicity of infection (MOI) of 1.0 to 0.3. Cultures were maintained for 42 days, during which complete X-Vivo15 and IL-2 and IL-15 cytokines were added as needed for cell expansion (maintaining a cell density of 3 x 10⁻⁶ cells / year). 5 and 2x10 6 Live cells / mL, and cytokine supplementation is given every Monday, Wednesday, and Friday during culture. Under these conditions, cells typically expand to approximately 10⁻⁶ cells / mL within 21 days. 9 Cells were harvested at the end of the culture cycle, washed twice, and prepared in clinical-grade cryopreservation medium (Cryostore CS5, BioLife Solutions).
[0101] On the day of T-cell infusion, the cryopreserved and released product was thawed, washed, and prepared for re-infusion. The cryopreserved vials containing the released cell product were removed from liquid nitrogen storage, thawed, cooled, and washed with PBS / 2% human serum albumin (HSA) wash buffer. After centrifugation, the supernatant was removed, and the cells were resuspended in preservative-free normal saline (PFNS) / 2% HSA infusion diluent. Samples were then used for quality control testing.
[0102] Example 5: Expression of Cltx-IgG4(EQ)-CD28gg-Zeta
[0103] Figure 1 C shows engineered healthy donor T cells (HD187.2 T cells) expressing CLTX-CAR. CM / SCM / N Flow cytometry analysis results. The images show anti-CD19, anti-Fc, and anti-CD8 staining, representing co-expression of CLTX-CAR and CD19t transgenes in both CD8+ and CD4+ (CD8-) T cell subsets. The percentage of immunoreactive cells in transduced (CLTX-CAR) and untransduced (mimic) cells 18 days after CD3 / CD28 bead stimulation is shown to demonstrate the ability to transduce human T cells with CLTX-CAR.
[0104] Example 6: Chlorine toxin and Cltx-IgG4(EQ)-CD28gg-Zeta T cells specifically recognize glioma cell lines U251
[0105] Chlorine toxin conjugated with the fluorescently labeled Cy5.5 (CLTX-Cy5.5) was used to evaluate the binding of chlorine toxins to various cell types. The results of this study were presented in... Figure 2 The cells in the AE array are shown as follows: (A) peripheral blood mononuclear cells (PBMCs) derived from healthy donors; (B) human EBV-transformed lymphoblastic cell line LCL; (C) human embryonic kidney line 293T transformed with large T antigen; (D) human astrocytes differentiated from induced pluripotent stem cells (iPSCs) derived from healthy donors; and (E) human glioblastoma cell line U251T). Cell lines were cultured in untreated medium or medium containing 1 μM CLTX-Cy5.5 at 37°C for 1 hour and then evaluated by flow cytometry.
[0106] like Figure 2 As shown in F, CLTX-CAR T cells specifically kill the glioma tumor cell line U251T without killing LCL, 293T, or primary human astrocytes. The number of live target cells (LCL, 293T, astrocytes, and U251T) co-cultured with CLTX-CAR T cells for 72 hours at an effector:target ratio of 1:1 (15,000 T cells, 15,000 target cells) was plotted relative to the number of live target cells co-cultured with simulated T cells for the same duration, at an effector:target ratio of 1:1 (15,000 T cells, 15,000 target cells).
[0107] Example 7: Chlorine toxin binds to low-passage PBT human glial cells in a manner independent of IL13Rα2 expression. Tumor
[0108] To examine whether chloramphenicol binding is independent of IL13Rα2 expression, cell lines were cultured for 1 hour in medium containing 1 μM CLTX-Cy5.5, followed by flow cytometry analysis of IL13RA2-low and IL13RA2-high cell lines stained with PE-conjugated IL13Rα2 antibody. Figure 3 As can be seen from AB, chloramphenicol binds to low-passage PBT human glioma lineage in a manner independent of IL13Rα2 expression.
[0109] Example 8: CLTX-IgG4(EQ)-CD28gg-ZetaT cells expressing IL13Rα2 and TGGA molecules independently. The subtype method identifies and kills low-passage PBT human glioblastoma lines.
[0110] like Figure 4 As shown in Figure A, CLTX-CAR T cells demonstrated statistically significant killing of a primary GBM cell line compared to the embryonic kidney cell line 293T. The plot shows the number of live target cells co-cultured with CLTX-CAR T cells for 24, 48, and 72 hours at an effector:target ratio of 1:1 (15,000 T cells, 15,000 target cells) after normalization relative to the number of live target cells co-cultured with simulated T cells for the same duration.
[0111] Figure 4 Image B shows the clearance of PBT003-4 and PBT009 tumor cells by CLTX-CAR T cells compared to the mimic control, as observed using live-cell imaging. Representative images of PBT003-4 and PBT009 cells co-cultured with mimic or CLTX-CAR T cells at an effector:target ratio of 1:4 (4,000 T cells, 16,000 target cells) were captured by bright-field microscopy immediately after co-culture (0 h) and 3 days after co-culture (72 h) at the mimic or CLTX-CAR T cell ratio.
[0112] Example 9: Activation of CLTX-IgG4(EQ)-CD28gg-ZetaT cells by stimulation with GBM cells
[0113] In the presence of protein transport inhibitors, T cells (mimicry or CLTX-expressing CARs) were stimulated for 5 hours via target cell stimulation at an effector:target ratio of 1:1 (25,000 T cells, 25,000 target cells). The percentage of CAR-T cells undergoing degranulation was determined by flow cytometry based on CD107a immunoreactivity. Figure 5 A), and detect cytokine production by intracellular staining ( Figure 5 B).
[0114] Example 10: CLTX-CAR T cells with different spacer designs effectively target tumor cells
[0115] Figure 6 A is a schematic diagram of a CLTX-CAR construct with different spacers (connectors), said spacers comprising IgG4Fc(EQ), IgG4(HL-CH3), CD8h, and a short connector (L). All have a CD28 transmembrane domain (not shown). Figure 6 As shown in B, CLTX-CAR T cells with different connectors were able to kill U251T GBM cells. The plot shows the number of live U251T cells co-cultured with T cells containing different CLTX retargeting constructs for 24, 48, and 72 hours, normalized relative to the number of live U251T cells co-cultured with simulated T cells for the same duration, at an effector:target ratio of 1:1 (15,000 T cells, 15,000 target cells). Figure 6 As shown in Figure C, CLTX-CAR T cells with different connectors exhibited varying levels of cytokine production after antigen challenge. T cells engineered with different CTLX-redirected constructs were stimulated with U251 T cells at an effector:target ratio of 1:1 (20,000 T cells, 20,000 target cells). IFN-γ secretion was detected by ELISA of the supernatant.
[0116] Example 11: Antitumor effects of CLTX-CAR T cells with different intracellular signal transduction domains
[0117] Figure 7 A is a schematic diagram of CLTX-CAR constructs with different intracellular co-stimulatory domains CD28 and 41BB. (See diagram for reference.) Figure 7 As shown in B, CLTX-CAR T cells with different co-stimulatory domains were able to kill U251T GBM cells. The plot shows the number of live U251T cells co-cultured with T cells containing different CLTX-redirected constructs, at an effector:target ratio of 1:1 (15,000 T cells, 15,000 target cells), after normalization relative to those co-cultured with Mock T cells for the same length of time. Figure 7 As shown in Figure C, CLTX-CAR T cells with different co-stimulatory domains produced various levels of cytokines after tumor attack. T cells engineered with constructs retargeted with different CLTX were stimulated with U251 T cells at an effector:target ratio of 1:1 (20,000 T cells, 20,000 target cells). IFN-γ secretion was detected by ELISA assay of the supernatant.

[0119] Figure 8 A is a schematic diagram of U251T xenograft growth and T-cell therapy in NSG mice. Mice with subcutaneously implanted U251T cells were treated with PBS (tumor only), mimic T cells, or CLTX-CAR T cells (days -14 to 0). Figure 8 B. CLTX-CAR T-cell therapy inhibits tumor progression. Tumor growth was measured using calipers within 20 days from the time of T-cell injection (day 0 to day 20).
[0120] Example 13: Another CLTX CAR
[0121] Figure 9-24 Various additional CLTX-CAR amino acid sequences were presented, which can be constructed and expressed as described above for the CLTX-IgG4(EQ)-CD28gg-Zeta CAR. Figure 8-24 In the diagrams, the multiple regions listed below the sequence, from the amino to the carboxyl terminus, are indicated by alternating underlined and ununderlined portions. Therefore, in... Figure 9In the diagram, the GMCSFRa signal peptide is underlined, the chloramphenicol sequence is not underlined, the spacer (IgG4(SmP)(L235E,N297Q)) is underlined, the CD28 transmembrane sequence is not underlined, the CD28cyto(LLmGG) co-stimulatory domain is underlined, the (Gly)3 sequence separating the co-stimulatory domain from the CD3zeta sequence is not underlined, and the CD3zeta sequence is underlined. Figure 9-23 The T2A and CD19t sequences co-expressed with CAR were not shown in the data. Figure 24 Depicting Figure 23 The CAR contains T2A (a ribosomal skipping sequence) and a truncated CD19. The truncated CD19 is co-expressed with the CAR, allowing for easy identification and quantification of transfected cells.
