Abstract
Description
[Technical Field]
[0001] This disclosure relates to the treatment of cancer using chimeric antigen receptor T cells. [Background technology]
[0002] 1. Chimeric antigen receptor T cell therapy Chimeric antigen receptor (CAR) T-cell therapy is a specific form of cell-based immunotherapy that uses genetically modified T cells to fight cancer. In CAR T-cell therapy, T cells are collected from the patient's blood, ex vivo engineered to express a CAR containing both an antigen-binding domain and a T-cell activation domain, expanded into a larger population, and administered to the patient. The CAR T cells act as living drugs, binding to cancer cells and causing their destruction. When successful, the effects of CAR T-cell therapy tend to be long-lasting, as evidenced by the detection of persistent and expanding CAR T cells in patients long after clinical remission.
[0003] 2. Structure and Function of CAR The antigen-binding domain of a CAR is an extracellular region that targets surface antigens on tumor cells. Suitable target antigens can be proteins, phosphorylated proteins, peptide-MHCs, carbohydrates, or glycolipid molecules. Ideal target antigens are widely expressed on tumor cells to enable targeting at a high rate of cancer cell activity. Ideal candidate target antigens are also typically expressed minimally in normal tissues, limiting off-tumor and on-target toxicity. The antigen-binding domain of a CAR contains a targeting moiety, such as an antibody single-chain variable region fragment (scFv), which is directed towards the target antigen.
[0004] The T cell activation domain of a CAR is located intracellularly and activates T cells in response to an antigen-binding domain that interacts with its target antigen. The T cell activation domain can contain one or more costimulatory domains, which are intracellular domains of known activated T cell receptors. Since costimulatory domains have different effects on the dynamics, cytotoxic function, and safety profile of CAR T cells, the selection and positioning of costimulatory domains within a CAR construct influences the function and fate of CAR T cells.
[0005] The extracellular antigen-binding domain and intracellular T-cell activation domain of a CAR are linked by a transmembrane domain, a hinge, and an optional spacer region. The hinge domain is a short peptide fragment that provides conformational freedom to facilitate binding to the target antigen on tumor cells. It can be used alone or in conjunction with a spacer domain that causes the scFv to protrude from the T-cell surface. The optimal length of the spacer depends on the proximity of the binding epitope to the cell surface.
[0006] CAR T therapy targeting B lymphocyte antigen CD19 (Kymriah®, Novartis) is considered promising for pediatric acute lymphoblastic leukemia, while CAR T therapy targeting B cell maturation antigen ("bb2121," a joint research project by Celgene® and Bluebirdbio®) is considered promising for relapsed / refractory multiple myeloma. More recent data suggest that CAR approaches may be effective against solid tumors. GD2 CAR natural killer T cell (NKT) therapy has shown activity in neuroblastoma (Heczey A, et al. Invariant NKT cells with chimeric antigen receptor provide a novel platform for safe and effective cancer immunotherapy. Blood;124(18):2824-33, 2014), and pembrolizumab-mediated mesothelin CAR T has shown antitumor effects against mesothelioma. However, further targets for treating solid tumors are needed.
[0007] 3. Challenges of CAR T-cell therapy Unfortunately, the complexity of CAR T cell-based therapies can lead to undesirable and dangerous consequences. Off-tumor effects such as neurotoxicity and acute respiratory distress syndrome are potential adverse effects of CAR T cell therapy and can be fatal. Cytokine release syndrome (CRS) is the most common acute toxicity associated with CAR T cells. CRS occurs when lymphocytes become highly activated and release excessive amounts of inflammatory cytokines. In patients with CRS, elevated levels of interleukin-2, interleukin-6, interleukin-1 beta, GM-CSF, and / or C-reactive protein in the serum are sometimes observed when these factors are measured. CRS is classified by severity and diagnosed as one of four grades (mild to severe), with more severe cases clinically characterized by high fever, hypotension, hypoxia, and / or multi-organ toxicity in the patient. One study reported that 92% of patients with acute lymphoblastic leukemia treated with anti-CD19 CAR T-cell therapy experienced CRS, and 50% of these patients developed grade 3–4 symptoms.
[0008] Therefore, further CAR T cell-based therapies are needed to enhance the capabilities of effective cancer treatment. However, new CAR T cell therapies must be devised that effectively treat cancer while minimizing the risk of dangerous inflammatory responses such as CRS.

The “effective dose” can be determined based on routine experiments with respect to the stated purpose.
[0067] 2. Overview This disclosure relates to compositions and methods for treating cancer using chimeric antigen receptor (CAR) cell therapy. More specifically, this disclosure relates to CAR cell therapy in which transformed cells, such as T cells, express CARs that target glypican 3 (GPC3). Furthermore, the CAR constructs, transformed cells expressing the constructs, and therapies utilizing the transformed cells disclosed herein may provide robust cancer treatment with minimal risk of cytokine release syndrome (CRS) or indiscriminate cytokine release in non-GPC3 expressing cells.
[0068] While we do not wish to be constrained by theory, GPC3 appears to be a viable cancer target across multiple modalities, including bispecific T cell engagers, CAR cells, and monoclonal antibodies and antibody-drug conjugates (ADCs). The carcinoembryonic antigen GPC3 is a GPI-conjugated heparin sulfate proteoglycan. GPC3 stabilizes the Wnt-Fzd interaction and stimulates Wnt signaling. GPC3 competes with patched for Hh binding, mitigates smoothed inhibition, and induces GPC3 degradation. Both pathways have been shown to stimulate hepatocellular carcinoma (HCC) proliferation. Furthermore, GPC3 expression levels have been shown to correlate with the stage and malignancy of HCC.
[0069] Furthermore, GPC3 is considered a promising target for CAR cell therapy. Therefore, antibodies and CAR constructs derived from these antibodies are being developed, as described herein.
[0070] 3. Design of CAR structures The CAR constructs of this disclosure may have several components, many of which can be selected based on the desired or refined function of the resulting CAR construct. In addition to the antigen-binding domain, the CAR construct may have a spacer domain, a hinge domain, a signal peptide domain, a transmembrane domain, and one or more costimulatory domains. Selecting one component from another (i.e., selecting a specific costimulatory domain of one receptor for a costimulatory domain of a different receptor) may affect the clinical efficacy and safety profile.
[0071] 4. Antigen-binding domain The antigen-binding domains intended herein may include an antibody or one or more antigen-binding fragments thereof. One intended CAR construct targeting GPC3 includes a single-chain variable region fragment (scFv) containing light and heavy chain variable regions derived from one or more antibodies specific to GPC3, which are either directly linked or linked via a flexible linker (e.g., repeats of GGGS having 1, 2, 3 or more repeats).
[0072] The antigen-binding domain of GPC3-targeting CARs, such as those disclosed herein, may exhibit altered binding affinity to the GPC3 protein. The relationship between binding affinity and potency can be more nuanced in relation to CARs compared to antibodies, where higher affinity is generally desirable. For example, preclinical studies on receptor tyrosine kinase-like orphan receptor 1 (ROR1)-CARs derived from high-affinity scFv (dissociation constant 0.56 nM) showed increased therapeutic index compared to low-affinity variants. Conversely, other examples have reported that manipulating scFv to lower affinity improves the identification of cells with altered antigen density. This may be useful for improving therapeutic specificity for antigens differentially expressed in tumor versus normal tissue.
[0073] Various methods can be used to confirm the binding affinity of the antigen-binding domain. In some embodiments, methodologies that exclude the avidity effect can be used. The avidity effect often involves multiple antigen-binding sites that interact simultaneously with multiple target epitopes in a multimerized structure. Thus, avidity functionally represents the cumulative strength of multiple interactions. An example of a methodology that excludes the avidity effect is that one or both of the interacting proteins are monomeric / monovalent, since multiple simultaneous interactions are not possible if one or both partners contain only a single interaction site.
[0074] 5. Spacer Domain The CAR constructs of this disclosure may have a spacer domain that provides conformational freedom to facilitate binding to the target antigen on the target cell. The optimal length of the spacer domain may depend on the proximity of the binding epitope to the target cell surface. For example, a proximal epitope may require a longer spacer, and a distal epitope may require a shorter epitope. In addition to promoting the binding of the CAR to the target antigen, achieving the optimal distance between the CAR cell and the cancer cell may also help sterically occlude large inhibitory molecules from the immunological synapse formed between the CAR cell and the target cancer cell. CARs targeting GPC3 may have a long spacer, an intermediate spacer, or a shorter spacer. The long spacer may contain the CH2CH3 domain (about 220 amino acids) of immunoglobulin G1 (IgG1) or IgG4 (natural or with modifications common to therapeutic antibodies such as the S228P mutation), while the CH3 region can itself be used to construct an intermediate spacer (about 120 amino acids). Shorter spacers may originate from segments (less than 60 amino acids) of CD28, CD8α, CD3, or CD4. Short spacers may also originate from hinge regions of the IgG molecule. These hinge regions may originate from any IgG isotype and may or may not contain mutations common in therapeutic antibodies, such as the S228P mutation mentioned above.
[0075] 6. Hinged Domain CARs targeting GPC3 may also possess a hinge domain. A flexible hinge domain is a short peptide fragment that provides conformational freedom to facilitate binding to the target antigen on tumor cells. It can be used alone or in conjunction with a spacer sequence. The terms "hinge" and "spacer" are often used interchangeably, and for example, an IgG4 sequence can be considered both a "hinge" and a "spacer" sequence (i.e., a hinge / spacer sequence).
[0076] CARs targeting GPC3 may further contain sequences containing signal peptides. These signal peptides stimulate cells to translocate the CAR to the cell membrane. Examples include IgG1 heavy chain signal polypeptide, Ig kappa or lambda light chain signal peptide, granulocyte-macrophage colony-stimulating factor receptor 2 (GM-CSFR2 or CSFR2) signal peptide, CD8a signal polypeptide, or CD33 signal peptide.
[0077] 7. Transmembrane domain CARs targeting GPC3 may further contain sequences including a transmembrane domain. This transmembrane domain may include a hydrophobic α-helix spanning the cell membrane. While the properties of the transmembrane domain have not been studied in as much detail as other aspects of CAR constructs, they may potentially influence CAR expression and its association with endogenous membrane proteins. The transmembrane domain may originate from, for example, CD4, CD8α, or CD28.
[0078] 8. Co-stimulatory domain CARs targeting GPC3 may further contain one or more sequences that form a co-stimulatory domain. A co-stimulatory domain is a domain that can enhance or modulate the response of immune effector cells. Co-stimulatory domains may include sequences from one or more of the following, for example: CD3 zeta (or CD3z), CD28, 4-1BB, OX-40, ICOS, CD27, GITR, CD2, IL-2Rβ, and MyD88 / CD40. The selection of the co-stimulatory domain affects the phenotype and metabolic signature of CAR cells. For example, CD28 co-stimulation results in a potent but short-lived effector-like phenotype with high levels of cytolytic ability, interleukin-2 (IL-2) secretion, and glycolysis. In contrast, T cells modified with CARs having a 4-1BB co-stimulatory domain tend to enlarge and persist longer in vivo, have increased oxidative metabolism, are less prone to depletion, and have an increased ability to generate central memory T cells.
[0079] 9.Cells CAR-based cell therapy can be used with various cell types, including lymphocytes. Specific cell types that can be used include T cells, natural killer (NK) cells, natural killer T (NKT) cells, invariant natural killer T (iNKT) cells, alpha-beta T cells, gamma-delta T cells, virus-specific T (VST) cells, cytotoxic T lymphocytes (CTLs), and regulatory T cells (Tregs). In one embodiment, the CAR cells used to treat the target are autologous. In other embodiments, the CAR cells may be derived from a genetically similar but not identical donor (allogeneic).
[0080] 10. CAR cell production The CAR constructs of this disclosure may include some combination of the modular components described herein. For example, in some embodiments of this disclosure, the CAR construct includes a GPC3-1 scFv antigen-binding domain. In some embodiments, the CAR includes a GPC3-2 scFv antigen-binding domain. In some embodiments of this disclosure, the CAR construct includes a CSFR2 signal peptide. In some embodiments, the CAR construct includes an IgG4P hinge / spacer domain having an S228P mutation.

In some embodiments, the CAR construct includes co-stimulatory domains derived from all of CD3z, CD28, and 4-1BB. In some embodiments, the CAR construct includes co-stimulatory domains derived from ICOS, OX-40, and / or GITR.
[0082] 11. Evaluation of CAR structures The constructs of this disclosure were compared and evaluated based on safety and the persistence and establishment of central memory. The low-affinity (high offrate) scFv GPC3-1 was well-rated for its good safety. The 4-1BB and CD3z co-stimulatory domains (both in the same construct) were well-rated based on their good persistence and contribution to a favorable in vivo phenotype (greater central memory). The GPC3-1 CAR and GPC3-2 CAR of this disclosure were comparable to published GPC3-targeted CAR-based constructs. Further evaluation details can be found in the examples.

[0112] The following examples illustrate specific embodiments of the Disclosure and various uses thereof. They are provided for illustrative purposes only and should not be construed as limiting the scope of the Disclosure. A glossary of terms is provided in Table 1.
[0113] [Table 1]
[0114] Example 1: Expression of GPC3 method GPC3 IHC was performed using the mouse monoclonal anti-human GPC3 antibody GC33 (Ventana). Secondary staining was performed using anti-mouse HRP. Human tissue microarrays (TMA, US Biomax) representing hepatocellular carcinoma (HCC), non-small cell lung cancer (NSCLC), ovarian cancer, or human colonic ganglion tissue were stained for GPC3 expression, and staining intensity and pattern were measured by microscopy.
[0115] result GPC3 overexpression is observed in 80% of HCC, 30% of squamous cell lung cancer, and 47% of ovarian clear cell carcinoma. However, GPC3 is undetectable by immunohistochemistry in normal liver tissue, including cirrhotic and hyperplastic samples, and its expression is low in normal tissue (e.g., lung). See Figures 1A and 1B.
[0116] Example 2: Development and affinity testing of scFv. overview In this example, anti-GPC3 scFv was developed, and their relative affinity for GPC3 was determined.
[0117] method GPC3-1 (SEQ ID NO: 1) and GPC3-2 (SEQ ID NO: 2) are almost identical. H It has domains (sequences 27 and 29), but V L The domains (SEQ ID NOs. 28 and 30; see Figure 2) are different. GPC3-2 has a complete germline framework, while GPC3-1 does not.
[0118] The apparent binding affinity was determined by the cell surface binding of soluble recombinant GPC3 protein to GPC3-1CAR and GPC3-2CAR expressed on the surface of Jurkat cells. The CAR constructs were expressed on the surface of Jurkat cells using a lentiviral vector. The cells were stained with recombinant His-tagged GPC3 protein (R&D systems) at various concentrations. The bound GPC3 was visualized by staining with a fluorescent-conjugated anti-His tag secondary antibody, and the cells were analyzed by flow cytometry. The binding curve was fit to a simple one-site binding model to determine the apparent K D was determined.
[0119] Alternative measurements of binding affinity were obtained using a BIAcore surface plasmon resonance system and GPC3-1 and GPC3-2 scFv-Fc fusion proteins. The purified scFv-Fc fusion molecules of GPC3-1 and GPC3-2 were covalently coupled to an amine-reactive SPR sensor chip (CM5, GE Healthcare). For GPC-1, soluble GPC3 protein (R&D Systems) was flowed over the chip surface at concentrations of 14, 28, 57, 114, and 228 nM and at a rate of 30 μL / min, and the interaction was monitored. For GPC3-2, concentrations of 4, 7, 14, 28, and 57 nM were flowed at the same flow rate. The data were fit using BIAevaluation software (GE Healthcare) and a simple 1:1 Langmuir binding model, and R max The fit was performed globally for k a , k d and K D The fit was performed locally.
[0120] Results In experiments evaluating soluble GPC3 binding to GPC3-1CAR and GPC3-2CAR expressed on the surface of Jurkat cells, K dThe values were approximately 15 nM for GPC3-1 and 5 nM for GPC3-2 (see Figure 3A). Surface plasmon resonance experiments using the same GPC3 protein and purified GPC3-1 / GPC3-2scFv-Fc fusion protein used for cell-based binding showed that the K levels of GPC3-1 and GPC3-2 were high. D The values were approximately 73 nM and 11 nM, respectively. See Table 1 and Figures 3B and 3C.
[0121] [Table 2]
[0122] Table 2 shows the reported Kd values for the four scFvs.
[0123] [Table 3]
[0124] Example 3. Development of a CAR structure and in vitro testing. overview In this example, an anti-GPC3 CAR construct was developed, and its cytokine activity and multifunctionality were tested.
[0125] method CAR structure. All CAR constructs used the CSFR2 signaling peptide (used in many clinical-stage CAR T constructs). The IgG4P (S228P mutation) hinge domain was used as a "spacer" between the scFv and the membrane, and the CD28 transmembrane domain was used. Different costimulatory domains were tested intracellularly, including various combinations of CD28, 4-1BB, and CD3 zeta costimulatory domains. Constructs using costimulatory domains from inducible T cell costimulatory factor (ICOS), OX40, and glucocorticoid-induced TNFR family-related genes (GITR) were also tested. The sequences of the GPC3-1 and GPC3-2 CAR constructs are shown in SEQ ID NOs: 3-10, and the corresponding nucleic acid sequences are shown in SEQ ID NOs: 11-18.
[0126] Other known CARs for GPC3 (based on GPC3-3 and GPC3-4 scFv) were constructed for comparison with the GPC3-1 and GPC3-2 CAR constructs. The GPC3-3 CAR contained a short IgG1 hinge, a CD28 transmembrane domain, a 4-1BB costimulatory domain, and a CD3 zeta intracellular domain. Another GPC3-3 CAR construct with both CD28 and 4-1BB costimulatory domains was also developed. The GPC3-4 CAR construct contained an IgG4P hinge, a CD28 transmembrane domain, and a 4-1BB costimulatory domain. The sequences of the GPC3-3 and GPC3-4 CARs are shown in SEQ ID NOs: 19-21, and the corresponding nucleic acid sequences are shown in SEQ ID NOs: 22-24.
[0127] Generation of CAR T cells. Purified human T cells are divided into 0.2 × 10⁻⁶ cells. 6 Cells were seeded in AIM-V medium containing 5% human serum and 1% penicillin-streptomycin at a concentration of cells / mL + IL-2 (300 IU / mL). T cells were activated with anti-CD3 / anti-CD28 Dynabeads (Invitrogen), and transduction was performed by spinoculation 24 hours later. Lentiviruses were added to the wells (MOI 100), the plates were centrifuged at 2000 rpm at 37°C for 2 hours, and placed in a 37°C, 5% CO2 incubator. The cell density was approximately 0.5–1 × 10⁶. 6 Cells were divided as needed to maintain the cell / mL concentration. The immunophenotype of CAR-T cells was first analyzed 7 days after transduction, and CAR-T cells were evaluated by in vitro and in vivo functional assays approximately 11 days after transduction.
[0128] Cell line testing. Various cell types were treated with CAR T cells containing different CAR constructs. In all cytokine tests, 5 × 10⁶ cells were used. 4Nine CAR-T cells were co-cultured with target cells in a 1:1 ratio in RPMI 10% FCS. After 24 hours, the supernatant was collected. Cytokines were analyzed using the Meso Scale Discovery 4-plex kit to detect IFN-γ, IL-2, TNF-α, and IL-10. Cytokine concentrations (picograms / milliliter) were measured.
[0129] Cytotoxicity tests were performed using cell impedance monitoring technology (xCELLigence). 3 × 10 4 Target cells were plated, and CAR-T cells were added 24 hours later in effector:target (E:T) ratios of 3, 1, or 0.3. After treatment with various CAR constructs, normalized cell indices were determined for Hep3B, Huh7, and SNU-182 cells. Hep3B expressed high GPC3 (14k / cell), Huh7 expressed medium / low GPC3 (7k / cell), and SNU-182 was GPC3-negative (0 / cell).
[0130] Multifunctionality tests were also conducted on the CAR constructs. Here, GPC3-1 BZ or the indicated CAR-T cells were co-cultured with Hep3B or A375 for 6 hours in the presence of Golgi Stop and a fluorescently labeled antibody against the degranulation marker CD107a. Binding to the target induced CAR-T degranulation, which in turn induced binding of the fluorescently labeled anti-CD107 present in the culture medium. The accumulation of CD107 detected by flow cytometry was directly proportional to the degree of degranulation, indicating target cell lysis. Since the cells were incubated in the presence of Golgi Stop, the production of effector cytokines (IFN-γ, IL-2, TNF-α) could also be evaluated by intracellular staining. Boolean gates combining each function (CD107a, IFN-γ, IL-2, and TNF-α) were generated using Flowtop, and a pie chart of the results was generated using Spice analysis software.
[0131] result The GPC3-2 and GPC3-3 constructs generally produced higher levels of TNFα and IL-2 compared to GPC3-1. Treatment with CAR T cells containing the GPC3-1 and GPC3-2 CAR constructs induced antigen-specific cytokines. On the other hand, the GPC3-4 BZ construct induced cytokines even in GPC3-negative cell types. The GPC3-1 and GPC3-2 constructs did not produce cytokines in the absence of the target. Cytokine production appears to be dependent on antigen density and antigen affinity. See, for example, Figures 4A and 4B.
[0132] The GPC3-1 and GPC3-2 constructs showed cytotoxicity only against GPC3-expressing cells, while the GPC3-4 construct showed cytotoxicity against both GPC3-positive cells (Hep3B and Huh7) and GPC3-negative cells (SNU-182). Low-affinity CARs (GPC3-1 BZ) exhibited cytotoxicity comparable to high-affinity (GPC3-2 BZ) CARs. See Figure 5.
[0133] GPC3-1 BZs exhibited cytotoxicity against HCC cell lines expressing low levels of GPC3. All target cells tested showed high susceptibility to GPC3-1 killing at E:T ratios of 3:1 and 0.3:1, with only one cell line with low GPC3 expression showing reduced death at an E:T ratio of 0.3:1. However, the completely equivalent death rates observed in our isogeneic GPC3-high and low Hep3B cell lines suggest that reduced antigen density is not a key factor limiting CAR-T mediated cytolysis. See Figure 6.
[0134] Both GPC3-2 and GPC3-1 CAR T cells are multifunctional regardless of the intracellular domain used. GPC3-1 BZ CAR T cells were multifunctional, with a higher proportion of cells exhibiting 2+ function. Furthermore, CAR T cells possessing CD28 were less multifunctional in vitro than CAR T cells possessing the 4-1BB intracellular domain. See Figure 7.
[0135] conclusion Treatment with GPC3-1 resulted in the lowest overall cytokine production of the tested CARs. Both GPC3-1 and GPC3-2 were multifunctional and showed specific cytotoxicity against cells expressing GPC3.
[0136] Example 4: In vivo testing of multiple CAR constructs in an animal model of hepatocellular carcinoma overview In this example, anti-GPC3 CAR constructs were tested in vivo, and their effects on body weight, tumor size, and survival were compared.
[0137] method 5 x 10 6 Hep3B cells were transplanted into the flanks of NSG mice (10 mice / group). The average tumor volume was 150 mm². 3 At this stage, mice were administered 4 million GPC3-2 BZ or GPC3-1 BZ. Body weight, tumor volume (2x / week), and survival were monitored. Animals whose body weight decreased to 80-90% were given nutritional supplements, and those whose body weight decreased to less than 80% were euthanized. The survival event (death) occurred at 1500 mm. 3 The determination was made based on tumor size exceeding a certain threshold. Each experiment was performed twice.
[0138] result Weight loss was observed with the use of the high-affinity GPC3-2 construct but not with the low-affinity GPC3-1 construct, indicating that the low-affinity binder is less toxic in vivo. GPC3-2-based CAR T cells were not tolerable at in vivo doses equivalent to those of GPC3-1-based CAR T cells. The greater toxicity of GPC3-2 BZ correlated with extensive infiltration of CAR T cells in the lungs of normal mice. Only a slight level of infiltration was observed in the lungs of mice treated with GPC3-1 BZ. See Figures 8A and 8B.
[0139] GPC3 CAR T induced Hep3B tumor regression in NSG mice. GPC3-1 BZ showed superior antitumor activity compared to GPC3-3 BZ and GPC3-4 BZ. See Figure 9.
[0140] GPC3-1 and GPC3-2 CAR T cells significantly extended the survival time of tumor-bearing NSG mice compared to GPC3-3 or GPC3-4 CAR T cells (p<0.01 vs. GPC3-3 BZ; Kaplan-Meier and Mantelcox-Logrank). See Figure 10. Similarly, it was determined that WPRE deletion did not have a negative functional effect on GPC3-1 BZ cells in vitro or in vivo.
[0141] conclusion Of the CARs tested, GPC3-1 BZ and GPC3-2 BZ showed the greatest antitumor activity and provided the greatest survival benefit. GPC3-1 BZ was less toxic and infiltrated normal tissue less than GPC3-2 BZ.
[0142] Example 5: In vivo comparison of GPC3-1 CAR structures overview In this example, multiple GPC3-1 CAR constructs containing different signaling domains were tested and compared in vivo.
[0143] method Analysis of differentiation and depletion. Differentiation and depletion of multiple GPC3-1 CAR constructs were investigated. Mice with Hep3B tumors were treated with CAR-T cells having different signaling domains (TZ=GPC3-1 TZ; BZ=GPC3-1 BZ; 28Z=GPC3-1 28Z), and the spleen and tumors were analyzed by flow cytometry 7 days after cell injection. Differentiation and depletion were assayed using FACs that detect multiple markers in spleen and tumor cells. The differentiation state of T cells was analyzed by combined expression of CD62L and CD45RO (CD62L+ / CD45RO-=naive; CD62L+ / CD45RO+=central memory; CD62L- / CD45RO+=effector memory; CD62L- / CD45RO-=effector memory cells re-expressing CD45RA (EMRA)). CD3% was used as a measure of persistence and expansion.
[0144] 5x10 on the mouse 6 Injecting individual Hep3B cells resulted in an average size of 150 mm. 3 The tumor was established. 4 million GPC3-1 BZ or GPC3-1 TZ T cells were administered to non-tumor-bearing mice or mice with Hep3B tumors. The effect on body weight in both tumor-bearing and non-tumor-bearing mice was measured up to 35 days after administration. Tumor volume was also assayed twice a week. Blood was collected regularly from the animals after administration for analysis of IFN-γ and TNF-α in the blood. Cytokines in the serum were analyzed 8 days after CAR-T administration. Each experiment was performed twice.
[0145] To investigate the potential peripheral neurotoxicity in GPC3+ tumor-bearing (Hep3B HCC strain) and non-tumor-bearing NSG mice, human anti-GPC3 CAR-T cells were administered to the animals. Histological examinations were performed on tumors and enteric nerve tissue from animals with Hep3B tumors treated with GPC3-1 BZ.
[0146] [Table 4]
[0147] result GPC3 CAR-T cells possessing a 4-1BB / CD3 zeta (BZ) signaling domain exhibit greater central memory and less depletion in vivo than CD28 / CD3 zeta (28Z) cells. The results indicate that splenic GPC3-1 BZ CAR T cells are less differentiated than GPC3-1 28Z CAR T cells, while retaining the ability to fully activate and differentiate in antigen-present tumors. See Figures 11A-11D.
[0148] GPC3-1 BZ showed persistence. Expression of the activation / waste markers LAG3 and PD1 confirmed that GPC3-1 BZ CAR T cells maintained fewer activated / wasted cells in the periphery. See Figure 12.
[0149] GPC3-1 BZ did not induce weight loss in either tumor-bearing or non-tumor-bearing mice at tumor regression doses. See Figure 13.
[0150] Complete tumor regression was observed only in GPC3-1 BZ CAR T cell-treated mice. See Figure 14.
[0151] Very small amounts of systemic cytokines (transient elevations of IFN-γ and TNF-α measured 7 days after the 8-day infusion) were detected. At effective CAR T doses, only very small and transient systemic cytokines were detected, and no weight loss was observed. Only human IFN-γ and TNF-α were transiently detected at elevated serum levels after the regression dose of CAR therapy. Further human or mouse cytokine levels, including hIL-2, mIL-10, mIL-6, mTNFα, and mIFNγ, were below the detection limit (BDL). See Figure 15.
[0152] As the tumor regressed, extensive T-cell infiltration and expansion were observed within the tumor. The tumors shrank due to a decrease in tumor cells, became necrotic, and were infiltrated by mononuclear cells. The mice used lacked lymphocytes, and therefore, any mononuclear cell infiltration is considered to be human CAR-T cells. See Figure 16. The enteric nervous system, which expresses only low levels of GPC3, was unaffected. See Figure 17. Very slight mononuclear cell infiltration was observed in the lungs and liver (data not shown).
[0153] conclusion Compared to constructs with other signaling domains, the GPC3-1 BZ construct is persistent, promotes the central memory response, and shows increased activity against tumors. Furthermore, treatment causes only a transient increase in some cytokines and does not cause weight loss. Treatment leads to T cell infiltration and necrosis in tumors, but normal tissues remain unaffected.
[0154] Example 6: Further characterization of GPC3-1 BZ CAR T cells overview In this example, GPC3-1 BZ CAR T cells were further characterized in treatment with cells of various tumor types and with different GPC3 expression levels. Cytokine responses were analyzed.
[0155] method Cytokine levels in response to treatment with GPC3-1 BZ CAR T cells were investigated in tumor types with various GPC3 expression levels. Immunohistochemical staining was also performed on representative Hep3B and Huh7 tumor xenografts.
[0156] GPC3 expression analysis was also performed on cells within tumor types. Staining intensity was graded on a scale of 1 to 4, with 1 being the lowest intensity and 4 being the highest. A staining intensity of 2 indicates low / medium intensity. Relative GPC3 expression was determined by FACs. GPC3 expression on Hep3B cells was determined by surface staining with a fluorescently labeled anti-GPC3 antibody and subsequent flow cytometry analysis. Based on GPC3 expression, Hep3B cells were gated as low, medium, or high expression cells, and the frequency of GPC3 in each gate was plotted.
[0157] Cytokine levels were measured by ELISA. Cell lines were co-cultured with GPC3-1 BZ CAR T cells in RPMI 10% FCS in a 1:1 ratio. After 24 hours, the supernatant was collected and cytokines were analyzed using the Meso Scale Discovery 4-plex Kit, detecting IFN-γ, IL-2, TNF-α, and IL-10. Cytokine analysis was performed after exposing cells to GPC3-1 BZ T cells for 24 hours. Cytokine levels were tested in different cell types after GPC3-1 BZ treatment.
[0158] result In GPC3-expressing cell lines, GPC3-1 BZ CAR T cell-induced cytokine production was proportional to surface GPC3 expression. See Figures 18-22.
[0159] GPC3-1 BZ CAR T cells did not induce a cytokine response in GPC3-negative or normal tissues. See Figures 23 and 24.
[0160] conclusion GPC3-1 BZ CAR T cells induce cytokine production at levels proportional to the GPC3 expression of the treated cells.
[0161] Example 7: Treatment with GPC3-1 CAR T cell construct and anti-cytokine antibody overview In this example, GPC3-1 CAR T cell therapy was attempted in combination with an anti-cytokine antibody.
[0162] method Tumors were treated with different combinations of GPC3-1 CAR T cell therapy and anti-cytokine antibodies. Hep3B tumor mice (10 mice / group) were administered 5 million GPC3-1 BZ or GPC3-1 TZ-transformed cells (TZ = truncated CD3 zeta, a non-signaling negative control) in or without 100 μg of anti-human TNFα (golimumab, Janssen) or anti-mouse IL-6 (Bio X Cell).
[0163] Using the HCC resistance model Huh7, high doses (1e7-3e7) of GPC3-1 CAR T cells were tested in combination with anti-TNF-α administration at two different time points. Mice with Huh7 tumors (10 mice / group) were administered the indicated doses of GPC3-1 BZ T cells (10 million or 3,000 cells), and 100 μg of anti-TNFα was administered on the same day as CAR T administration (day 0) or two days after the start of treatment (day 2).
[0164] result Blocking TNF-α instead of IL-6 eliminated the effectiveness of GPC3-1 benzoate. See Figure 25.
[0165] In the resistant HCC model Huh7, higher doses of CAR T cells were required to induce tumor growth inhibition, but these higher doses were also associated with CRS-like symptoms and weight loss. Weight loss was reversed by delayed administration of anti-TNFα to achieve tumor growth inhibition. See Figures 26A-26C.
[0166] conclusion The use of anti-TNFα therapy in combination with GPC3-1 benzodiazepine therapy can mitigate the effects of weight loss caused by high-dose CAR T-cell therapy.
