AI Technical Summary
Current cancer immunotherapy methods, such as allogeneic stem cell transplants and non-transplant donor lymphocyte infusions, face challenges in effectively reversing T cell exhaustion and inducing tumor regression while minimizing graft-versus-host disease and sustained engraftment toxicity, particularly in treating solid tumors.
Development of allogeneic lymphocyte compositions comprising CD4+ T cells modified to enhance anti-tumor activity by increasing the frequency and resistance to exhaustion, and depletion of CD8+ T cells to reduce toxicity, using specific genetic and pharmacological inhibitors to target pathways like BTK, ITK, and PI3Kδ, and promoting a Th1 CD4+ T cell differentiation state.
The approach enhances anti-tumor immune responses, reduces toxicity, and minimizes graft-versus-host disease by reversing T cell exhaustion and promoting a favorable immune environment, thereby improving treatment efficacy against both hematological and solid tumors.

CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of priority under 35 U.S.C. § 119(e) to U.S. Provisional Application Serial Nos. 63 / 250,061, filed September 29, 2021; 63 / 287,890, filed December 9, 2021; and 63 / 332,616, filed April 19, 2022. The disclosures of the prior applications are deemed to be part of the disclosure of this application in their entireties and are incorporated herein by reference. [Technical field]
[0002] The present disclosure relates generally to allogeneic lymphocyte compositions, and more specifically to the use of such compositions in methods of increasing the efficacy and reducing the toxicity of non-transplant CD8-depleted allogeneic donor lymphocyte infusions. [Background technology]
[0003] Cancer immunotherapy has emerged as a promising cancer treatment. The goal of cancer immunotherapy is to harness the immune system to selectively destroy cancer cells while sparing normal tissue.
[0004] Cytotoxic CD8+ T cells are a major population of immune cells that control and eliminate tumor cells. Zhang et al., (2020), Front. Cell Dev. Biol., 8:17. However, T cells are not as effective against cancer as expected. Due to immune tolerance and immune suppression mechanisms, CD8+ T cells are often suboptimally primed and for these and other reasons become ineffective or enter a dysfunctional state known as T cell exhaustion. T cell exhaustion reduces the ability of cytotoxic CD8+ T cells to kill cancer cells, leading to attenuated effector functions that lead to tumor progression.
[0005] There has been considerable interest in developing methods to revive or replace exhausted T cells to restore anti-tumor immune responses, but developing effective methods to revive exhausted T cells remains a challenge.
[0006] Allogeneic T-cell therapy is a form of cancer immunotherapy in which lymphocytes are harvested from the peripheral blood or bone marrow of healthy donors and infused into cancer patients. This treatment is usually performed in the form of allogeneic stem cell transplantation, where patients undergo extensive immunosuppressive conditioning and are then infused with a stem cell graft containing an unselected population of mature T cells. The aim of allogeneic stem cell transplantation is to obtain sustained engraftment of donor cells, but it is associated with significant toxicities, including graft-versus-host disease (GVHD), an immunological attack against normal tissues, and this therapy has not proven effective in treating solid tumor malignancies. International Application No. PCT / US2013 / 032129 describes an approach called non-transplant donor lymphocyte infusion, in which patients are treated with lymphodepleting chemotherapy followed by infusion of CD8+ cell-depleted peripheral blood cells from healthy, partially or completely human leukocyte antigen (HLA)-mismatched donors. The proposed therapeutic mechanism of mismatched CD8-depleted donor lymphocyte infusion (DLI) is that alloreactive donor CD4+ T cells secrete cytokines and signal through recipient antigen-presenting cells (APCs) to reverse the exhaustion of recipient-derived tumor-specific CD8+ T cells. Although this therapy can induce antitumor responses against hematological malignancies, its efficacy against solid tumors is limited, possibly by reversion of tumor-specific CD8+ T cells to an exhausted state.
[0007] Thus, there remains an unmet need for methods to efficiently and persistently awaken exhausted T cells and induce tumor regression while reducing the risk of persistent engraftment and graft-versus-host disease. Summary of the Invention [Problem to be solved by the invention]
[0008] The present disclosure relates to allogeneic lymphocyte compositions and methods for increasing the efficacy and reducing the toxicity of non-transplant CD8-depleted allogeneic lymphocyte infusions.
[0009] The present disclosure provides allogeneic lymphocyte compositions that contain CD4+ T cells that have been modified to deplete CD8+ T cells and enhance in vivo anti-tumor activity. Without being committed to a particular mechanism, the modifications include depleting CD4+ T cells from type 1, i.e., T, which secrete interferon gamma (IFNγ) and provide optimal help to the recipient's CD8+ T cells. h 1 It can increase the frequency of CD4+ T cells or make CD4+ T cells more resistant to exhaustion or suppression of activity. The allogeneic lymphocyte composition can provide a source of CD4+ T cell help to reverse T cell exhaustion in the subject, while depletion of donor CD8+ T cells reduces the risk of persistent engraftment and graft-versus-host disease. In addition to helping restore exhausted CD8+ T cells, it can also help restore donor T h 1 cells can reprogram the tumor microenvironment to be immunostimulatory and reverse CD8+ T cell exhaustion while suppressing graft-versus-host disease toxicity.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0043] The present disclosure relates to allogeneic lymphocyte compositions and methods for increasing the efficacy and reducing the toxicity of non-transplant CD8-depleted allogeneic lymphocyte infusions.
[0044] The present inventors have developed an allogeneic lymphocyte composition enriched for CD4+Th1 cells and depleted of CD8+T cells. Without being bound by theory or mechanism, the present inventors believe that this allogeneic lymphocyte composition can provide a source of CD4+T cells that can reduce immune suppression and / or increase immune system activation and / or provide signals that reverse CD8+T cell exhaustion upon infusion, restoring endogenous anti-tumor responses while minimizing the risk of sustained engraftment and graft-versus-host disease.
[0045] The allogeneic lymphocyte composition disclosed herein includes a plurality of isolated white blood cells, which can be obtained from a donor subject or another source, such as umbilical cord blood or cell line. The white blood cells can be mismatched with the recipient for at least one human leukocyte antigen (HLA) class II allele in the donor-to-recipient (graft-to-host) direction to the recipient subject. Alternatively, the donor can include at least one HLA class II allele mismatch with the recipient and at least one HLA class II allele match with the recipient in the donor-to-recipient (graft-to-host) direction. The mismatch or match of the HLA class II allele can be found in HLA-DRB1, HLA-DQB1, or HLA-DPB1. For the purpose of the present treatment, low-expressed HLA class II molecules, such as HLA-DPA1, HLA-DQA1, and HLA-DRB3, -DRB4, and -DRB5, may not be considered. In some examples, the allogeneic compositions disclosed herein may include a plurality of isolated white blood cells obtained from a cell line or umbilical cord blood, modified or unmodified to target a specific target. The cell line may be HLA class II allele matched, partially matched, or mismatched to the subject.
[0046] The leukocytes may be depleted of CD8+ T cells by about 10-fold or more compared to undepleted leukocytes. The leukocytes may be further modified to inhibit Bruton's tyrosine kinase (BTK), interleukin 2-inducible T cell kinase (ITK), phosphatidylinositol 3 kinase delta isoform (PI3Kδ), helios, blimp1, SOCS1, GATA3, IL-10, STAT3, TOX, CD25, foxp3, Ezh2, TGF-β receptor II, LAG-3, PD-1, TNF-α, or a combination thereof. Without wishing to be bound by theory or mechanism, the inventors believe that inhibition of BTK, ITK, PI3Kδ, helios, blimp1, SOCS1, GATA3, IL-10, STAT3, TOX, CD25, foxp3, Ezh2, TGF-β receptor II, LAG-3, PD-1, TNF-α, or a combination thereof, can promote differentiation of naive CD4+ T cells into a state favorable for helping effector cells of antitumor or antiviral immunity, such as type 1 (Th1) CD4+ T cells, or prevent post-naive CD4+ T cells from converting into cells with suboptimal helper activity for antitumor or antiviral immunity. For example, a portion of T cells can be preferentially differentiated into a subtype of CD4+ T cells (e.g., Th1). Inhibition of BTK, ITK, PI3Kδ, helios, blimp1, SOCS1, GATA3, IL-10, STAT3, TOX, CD25, foxp3, Ezh2, TGF-β receptor II, LAG-3, PD-1, TNF-α, or combinations thereof, can also prevent naive CD4+ T cells from differentiating into states that are not optimal for promoting anti-tumor or anti-viral immunity, such as Th2, Th17, or regulatory T cells, or can prevent CD4+ T cells from becoming exhausted or being suppressed by other cells from mediating anti-tumor or anti-viral activity.
[0047] Certain exemplary and preferred embodiments are described in further detail herein, and the embodiments within this specification should not be construed as limiting the scope of the present disclosure.
[0048] A. Composition of allogeneic lymphocytes The present disclosure relates to an allogeneic lymphocyte composition. The allogeneic lymphocyte composition includes isolated leukocytes obtained from a donor. The donor may include at least one HLA class II allele mismatch to the recipient in the donor-to-recipient (graft-versus-host, or GVH) direction. The HLA class II allele mismatch may be found at HLA-DRB1, HLA-DQB1, or HLA-DPB1.
[0049] Donors who have not been vaccinated against one or more tumor-specific antigens, including neoantigens, generally have a low frequency of tumor-specific CD4+ T cells. When using donors who have not been vaccinated against one or more tumor-specific antigens, the ability of the immune system to restore endogenous antitumor immunity is based on the activity of alloreactive CD4+ T cells, so HLA class II matching between donor and recipient is not required.
[0050] When vaccinating donors against tumor-specific antigens or expanding tumor-specific CD4+ T cells ex vivo, some degree of HLA class II allele matching is necessary because the expanded tumor-specific CD4+ T cells are restricted to the donor's HLA class II molecules and are predicted to be ineffective in providing help in the recipient unless the recipient expresses at least one HLA class II molecule shared by the donor. Among HLA class II molecules, the preferred molecules for sharing are the highly expressed molecules HLA-DRB1>HLA-DPB1>HLA-DQB1>>>HLADRB3,4,5=HLA-DQA1.
[0051] The donor may be partially or completely mismatched in HLA class II alleles, such as HLA-DRB1, HLA-DQB1 and HLA-DPB1, in the donor's anti-recipient (GVH) direction. The donor may be partially or completely mismatched in HLA class II alleles, such as HLA-DRB1, HLA-DQB1 and HLA-DPB1, and completely matched for class I alleles. The donor may be completely mismatched with the unshared HLA of the first-degree relative of the recipient who is a candidate for allogeneic stem cell transplantation.
[0052] The donor's leukocytes may be stimulated in vivo or ex vivo to increase the frequency of CD4+ T cells that proliferate and / or secrete IFNγ in response to tumor or viral antigens compared to unstimulated leukocytes. This stimulation may consist of deliberate in vivo vaccination of the donor against tumor or viral antigens. Alternatively, or in addition, the donor's leukocytes, including CD4+ T cells, may be stimulated ex vivo with antigen-presenting cells (APCs), such as dendritic cells, pulsed with tumor or viral antigens in the presence or absence of cytokines that polarize the CD4+ T cells. The tumor or viral antigens may be present in the recipient. If the donor is immunized or donor cells are stimulated ex vivo with antigen-pulsed APCs, the donor must contain at least one HLA class II allele match to the recipient. The HLA class II allele match may be found in HLA-DRB1, HLA-DQB1, or HLA-DPB1. In embodiments, the immunized donor may have at least one HLA class II allele mismatch to the recipient in the donor-to-recipient (graft-versus-host) direction and at least one HLA class II allele match to the recipient. If the donor's leukocytes have not been stimulated to increase the frequency of tumor-specific or virus-specific CD4+ T cells, the donor's HLA class II molecules HLA-DRB1, HLA-DQB1, and HLA-DPB1 may be completely mismatched to the recipient in the donor's anti-recipient (GVH) direction.
[0053] In embodiments, the allogeneic lymphocyte composition may include leukocytes obtained from a cell line or umbilical cord blood.
[0054] Donor samples can be obtained from cord blood banks.When donor samples are obtained from cord blood banks, desirable samples may contain infrequent and / or rare HLA alleles, because subjects are unlikely to contain serum antibodies against infrequent and / or rare HLA allele types.Exemplary rare alleles include, but are not limited to, A*24:41, B*07:02:28, B*35:03:03, B*39:40N, DRB1*13:23, DRB1*14:111, B*44:16 and DRB1*01:31, C*06:49N, B*37:03N, A*24:312N and A*30:76N.
[0055] In an embodiment, the recipient may not have detectable antibodies that are reactive to the HLA of the donor.Detectable antibodies can be determined using conventional methods known to those skilled in the art.For example, the recipient must not have antibodies that are detectable by complement-dependent cytotoxicity against the HLA molecules of the donor in flow cytometry cross-match assay, or a mean fluorescence intensity (MFI) of 3000 or more in solid-phase immunoassay, because positive results are undesirable.
[0056] The number of natural killer cells in the allogeneic composition may be less than or equal to the number of natural killer cells in the peripheral blood composition.
[0057] In an embodiment, the CD4+ T cells present in the composition are not activated ex vivo.
[0058] The white blood cells present in the allogeneic composition are depleted of CD8+ T cells. The CD8+ T cells can be depleted by any known method. For example, the CD8+ T cells can be depleted using a magnetic bead cell sorter or flow cytometry. The depletion of CD8+ T cells can involve the use of anti-CD8+ antibodies bound to magnetic particles, or anti-CD8+ antibodies plus complement.
[0059] The white blood cells are approximately 1 / 2, 1 / 3, 1 / 4, 1 / 5, 1 / 6, 1 / 7, 1 / 8, 1 / 9, 1 / 10, 1 / 15, 1 / 20, 1 / 25, 1 / 30, 1 / 35, 1 / 40, 1 / 45, 1 / 50, 1 / 55, 1 / 60, 1 / 65 about one in, about one in 70, about one in 75, about one in 80, about one in 85, about one in 90, about one in 95, about one in 100, about one in 200, about one in 300, about one in 400, about one in 500, about one in 600, about one in 700, about one in 800, about one in 900, about one in 1,000 or more CD8+ T cells are depleted.
[0060] The leukocytes of the allogeneic lymphocyte compositions disclosed herein are further modified to inhibit the activity of BTK, ITK, or PI3Kδ, helios, blimp1, SOCS1, GATA3, IL-10, STAT3, TOX, CD25, foxp3, Ezh2, TGF-β receptor II, LAG-3, PD-1, TNF-α, or a combination thereof. Without wishing to be bound by theory or mechanism, the inventors believe that suppression of BTK, ITK, PI3Kδ, helios, blimp1, SOCS1, GATA3, IL-10, STAT3, TOX, CD25, foxp3, Ezh2, TGF-β receptor II, LAG-3, PD-1, TNF-α, or a combination thereof, can promote differentiation of naive CD4+ T cells into a state favorable for helping effector cells of antitumor or antiviral immunity, such as type 1 (Th1) CD4+ T cells, or prevent post-naive CD4+ T cells from being converted into cells with suboptimal helper activity for antitumor or antiviral immunity. For example, a portion of T cells can be preferentially differentiated into CD4+ T cell subtypes, such as Th1. Alternatively, differentiation of T cells into another CD4+ T cell subtype (e.g., Th2 or Treg) can be suppressed. Without wishing to be bound by theory or mechanism, the inventors also believe that inhibition of BTK, ITK, PI3Kδ, helios, blimp1, SOCS1, GATA3, IL-10, STAT3, TOX, CD25, foxp3, Ezh2, TGF-β receptor II, LAG-3, PD-1, TNF-α, or combinations thereof in leukocytes (e.g., donor leukocytes) may enhance the efficacy and reduce the toxicity of non-transplant allogeneic donor lymphocyte infusions.
[0061] CD4+ T cells are T lymphocytes that express a T cell receptor that recognizes peptide antigens presented in the context of class II major histocompatibility complex (MHCII) molecules. Tay et. al. (2021), Cancer Gene Therapy, 28:5-17. CD4+ T cells can differentiate into any of several diverse functional subtypes in response to context-dependent signals, and thus provide "help" to appropriate effector immune cells in their primary role as central coordinators of the immune response. CD4+ T cells mediate antitumor immunity primarily by providing support to CD8+ T cell and antibody responses, inducing the tumoricidal capacity of macrophages, secreting effector cytokines such as IFNγ and tumor necrosis factor alpha (TNF-α), and, under certain circumstances, direct cytotoxicity against tumor cells.
[0062] CD4+ T cells can differentiate into Th1 cells expressing IFNγ and TNF-α, Th2 cells expressing IL-4, IL-5 and IL-13; Th9 cells expressing IL-9 and IL-21; Th17 cells expressing IL-17; TFH cells expressing IL-6 and IL-21; and Treg cells expressing TGFβ and IL-10. Tay et. al. (2021), Cancer Gene Therapy, 28:5-17.

The expression levels of cytokines expressed by CD4+ T cells can be measured by those skilled in the art using conventional methodologies, such as ELISA or intracellular cytokine staining followed by cell surface staining and flow cytometry.
[0071] i.BTK BTK is a member of the Tec family of non-receptor tyrosine kinases, which consists of PH, TH, SH3, SH2 and catalytic domains. BTK is involved in the signal transduction of multiple receptors, including growth factor receptors, cytokine receptors, G protein-coupled receptors, antigen receptors and integrins. BTK then activates many key downstream signaling pathways that control cell migration, adhesion, survival and proliferation.
[0072] BTK can be suppressed (i.e., inhibited) by pharmacological agents or genetic recombination. The pharmacological agent can be an inhibitor of BTK. Suitable inhibitors of BTK include, but are not limited to, acalabrutinib, zanubrutinib, tirabrutinib, evobrutinib, trebrutinib, rilzabrutinib, remibrutinib, tirabrutinib, branebrutinib, orelabrutinib, BIIB091, AC0058, PRN473LFM-A13, dasatinib, GD-4059, or AVL-292. The inhibitor can be a small molecule, a small interfering RNA (siRNA), or a short hairpin RNA (shRNA). In an embodiment, the BTK inhibitor used herein is not ibrutinib. The BTK inhibitor may have a half inhibitory concentration of less than about 1000 nM, less than about 900 nM, less than about 800 nM, less than about 700 nM, less than about 600 nM, less than about 500 nM, less than about 400 nM, less than about 300 nM, less than about 200 nM, or less than about 100 nM.
[0073] TK can be inhibited by deleting or "knocking out" the BTK gene from the genome. Techniques for knocking out genes are known to those skilled in the art. Gene knockout methods in the art include, but are not limited to, gene silencing, conditional knockout, homologous recombination, gene editing, and mutational knockout. Gene silencing can be achieved, for example, using RNA interference, siRNA, or shRNA. Conditional knockout methods can be used to inactivate the BTK gene. Loss-of-function mutations can help suppress gene function by creating mutations in the BTK gene. Gene editing techniques that can be employed to inhibit BTK include, but are not limited to, zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), meganucleases, and CRISPR-based systems (e.g., CRISPR-Cas9). Commercially available kits can also be used to inhibit BTK. Mutations can be created in one or more protein domains. For example, mutations can be made in the pleckstrin homology domain, the proline-rich TEC homology (TH) domain or the SRC homology domain (SH2 or SH3).
[0074] Inhibition of BTK can decrease the number or frequency of Th2 polarized T cells in white blood cells. Inhibition of BTK can increase the number or frequency of Th1 polarized T cells in white blood cells. Inhibition of BTK can promote the differentiation of T cells into Th1.

[0080] Cytokine release syndrome is a known complication of the treatment of hematological malignancies with chimeric antigen receptor-modified (CAR) T cells or with T cell-replete, HLA haploidentical blood or bone marrow transplants. In embodiments, inhibition of BTK can reduce cytokine release syndrome following non-transplanted CD8-depleted lymphocyte infusions.

[0085] ii.ITK Interleukin-2 (IL-2)-inducible T cell kinase (ITK) is a non-receptor tyrosine kinase highly expressed in T cell lineages and regulates various aspects of T cell development and function, primarily through its functions downstream of the T cell receptor.
[0086] ITK can be suppressed (i.e., inhibited or attenuated) by pharmacological agents or genetic recombination. The pharmacological agent can be an inhibitor of ITK. Suitable inhibitors of ITK include, but are not limited to, aminothiazole, aminobenzimidazole, indole, pyridine or prn694. The inhibitor can be a small molecule, a small interfering RNA (siRNA) or a short hairpin RNA (shRNA). The ITK inhibitor can have a half-maximal inhibitory concentration of less than about 1000nM, less than about 900nM, less than about 800mM, less than about 700nM, less than about 600nM, less than about 500nM, less than about 400nM, less than about 300nM, less than about 200nM, less than about 100nM.

[0269] The dosage is determined by the attending physician and other clinical factors. The dosage for a single patient varies depending on many factors, such as the patient's size, body surface area, age, sex, the specific compound administered, administration time and route, type of treatment, general health status, and other drugs administered at the same time. "Effective amount" refers to the amount of active ingredient that is sufficient to affect the course and severity of the disease and to reduce or ameliorate such pathology, and can be determined using known methods.
[0270] C. Preparation method The present disclosure also relates to a method of preparing an allogeneic lymphocyte composition as disclosed herein. The method includes obtaining a peripheral blood cell composition from a donor subject that is allogeneic to a recipient subject, or from a cell line or umbilical cord blood. The peripheral blood cell composition can be a whole blood product or an apheresis product. The peripheral blood cell composition can be obtained using means known in the art, such as, for example, venipuncture. The peripheral blood cell composition includes both CD8+ and CD4+ T cells. The peripheral blood cell composition can be obtained from a human or non-human subject. Preferentially, the peripheral blood cell composition is obtained from a human.
[0271] The white blood cells from the donor subject may be mismatched with the recipient subject for at least one HLA class II allele mismatch in the donor-to-recipient (graft-to-host) direction to the recipient subject. Alternatively, the donor may have at least one HLA class II allele mismatch with the recipient in the donor-to-recipient (graft-to-host) direction and at least one HLA class II allele match with the recipient. The HLA class II allele mismatch or match may be HLA-DRB1, HLA-DQB1 or HLA-DPB1.
[0272] When the donor and the recipient are ABO blood type incompatible and the allogeneic white blood cell composition contains a large number of red blood cells, making the allogeneic lymphocyte composition may further include reducing the number of red blood cells. As used herein, "ABO blood type incompatibility" refers to when the recipient has a major ABO red blood cell incompatibility with the donor, such as when the recipient has blood type O and the donor has blood type A, B or AB, when the recipient has blood type A and the donor has blood type B or AB, or when the recipient has blood type B and the donor has blood type A or AB. The number of red blood cells may comprise a packed volume of about 50 mL or less, for example, a packed volume of about 50 mL or less, preferably a packed volume of about 30 mL or less, and further, "packed volume" should be defined, for example, centrifugation of the lymphocyte composition provides a packed volume of 50 mL or less of red blood cells, and a measured volume sample of the lymphocyte composition may also be screened to provide a proportionally representative volume of packed blood cells.
[0273] Mononuclear cells are then isolated from the peripheral blood cell composition, for example, by Ficoll-Hypaque gradient separation. The number of CD8+ cells in the white blood cells can then be reduced. The number of CD8+ cells in the white blood cells can be reduced by about 1 / 2, about 3 / 4, about 5 / 6, about 7 / 8, about 9 / 10, about 15 / 10, about 20 / 25, about 30 / 35, about 40 / 45, about 50 / 55, about 6 / 10, about 8 / 15, about 9 / 10, about 11 / 15, about 12 / 10, about 13 / 10, about 14 / 15, about 15 / 10, about 16 / 10, about 17 / 10, about 18 / 10, about 19 / 11, about 20 / 25, about 25 / 30, about 26 / 10, about 27 / 10, about 28 / 10, about 29 / 10, about 30 / 35, about 31 / 32, about 32 / 36, about 33 / 37, about 34 / 38, about 35 / 39, about 36 / 40, about 37 / 45, about 38 / 46, about 39 / 47, about 39 / 48, about 39 / 49, about 40 / 50, about 40 / 5 ...0, about 40 / 50, about 40 The amount of removal can be about 1 in 0, about 1 in 65, about 1 in 70, about 1 in 75, about 1 in 80, about 1 in 85, about 1 in 90, about 1 in 95, about 1 in 100, about 1 in 200, about 1 in 300, about 1 in 400, about 1 in 500, about 1 in 600, about 1 in 700, about 1 in 800, about 1 in 900, about 1,000 or more.
[0274] The leukocytes are further engineered to inhibit BTK, ITK, or PI3Kδ, helios, blimp1, SOCS1, GATA3, IL-10, STAT3, TOX, CD25, foxp3, Ezh2, TGF-β receptor II, LAG-3, PD-1, TNF-α, or combinations thereof. Without wishing to be bound by theory or mechanism, the inventors believe that inhibition of BTK, ITK, PI3Kδ, helios, blimp1, SOCS1, GATA3, IL-10, STAT3, TOX, CD25, foxp3, Ezh2, TGF-β receptor II, LAG-3, PD-1, TNF-α, or a combination thereof, can promote differentiation of naive CD4+ T cells into a state favorable for helping effector cells of antitumor or antiviral immunity, such as type 1 (Th1) CD4+ T cells, or prevent post-naive CD4+ T cells from converting into cells with suboptimal helper activity for antitumor or antiviral immunity.

[0291] This invention is further illustrated by the following examples, which are not intended to be limiting in any way. EXAMPLES
[0292] Example 1. Donor E7 priming, ex vivo expansion, and T cell proliferation in E7-expressing head and neck cancer mouse models hVerification of antitumor effect of 1-polarization
[0293] The experimental goal was to test the efficacy of exogenous CD4+ T cell help against endogenous antitumor effectors in a mouse model of HPV-associated head and neck cancer. Table 1 shows the drugs and treatment protocol for this study.
[0294] [Table 1]
[0295] CD8- refers to the depletion of CD8+ T cells. CD8+ depletion is performed using Miltenyi CD8 depletion columns.
[0296] For ex vivo expansion, mouse dendritic cells (DCs) are enriched using a mouse pan-dendritic cell isolation kit (Miltenyi Biotech). DCs are pulsed with 1 μg / mL each of HPV16 E6 and E7 peptides (JPT Peptide Technologies) for 2 h in RPMI1640 (complete medium) containing 2 mmol / L L-glutamine, 100 U / mL penicillin, 100 μg / mL streptomycin, and 10% heat-inactivated fetal bovine serum. E6 / E7-pulsed DCs are then transferred to flasks containing mouse splenocytes (treated with 1 μM ITK inhibitor for 1 h before mixing) in a 1:20 ratio with complete medium containing 25 U / mL recombinant mouse IL-2 and 20 ng / mL recombinant mouse GMCSF and cultured for 5 days. Cells are then washed and rested for 2 days in complete medium + IL-2 and GM-CSF before restimulation.
[0297] ITK samples (i.e., groups 9 and 10) are exposed ex vivo to 1 μM ITK inhibitor for 1 h before incubation with peptide-pulsed dendritic cells and cytokines.
[0298] ICB refers to immune checkpoint blockade. ICB is performed on day 2 where indicated using RMP1-14 (anti-PD1; BioXCell) 100 mg IP in 100 mL HBSS and 10F.9G2 (anti-PD-L1; BioXCell) 100 mg IP in 100 mL HBSS.
[0299] Example 2. T of CD4+ T cells h Characterization of the fate and efficacy of ex vivo expanded E7-primed donor T cells under conditions designed to favor one phenotype We previously showed that in a syngenic cell transplantation model, primed whole spleens were curative, whereas primed CD8-depleted spleens conferred no benefit. + After infusion, T cells are T h 2 or T reg Such alternatives (i.e. non-T h 1) CD4 + We hypothesize that the T h 1. Ex vivo expansion of E7-specific T cells and in vivo T h We hypothesized that deletion of ITK as a means to promote retention of the CD4+ phenotype would enhance the antitumor efficacy of infusions in a syngenic model. + Among T cells, T h These manipulations promote the CD4.1 phenotype. + T cell T reg We hypothesized that this would prevent the conversion to
[0300] The goal of this study was to characterize the fate and efficacy of E7-primed donor T cells expanded ex vivo under conditions designed to favor a Th1 phenotype in CD4+ T cells. Table 2 lists the agents and treatment protocol for this study.
[0301] [Table 2]
[0302] Three mice per group will be sacrificed at 1, 2 and 3 weeks after DLI. Spleen cells will be stimulated with dendritic cells pulsed with the overlapping pentadecapeptide of E7 (JPT peptide). E7-specific donor CD4+ T cell status will be characterized by intracellular staining for IFN-γ, IL-4, IL-17A or foxp3, and extracellular staining for CD4 and CD45.1, followed by flow cytometry.
[0303] It is believed that primed E7-specific CD4+ T cells become exhausted or convert to alternative CD4 phenotypes (e.g., Th2, Th17, Treg). In the syngenic model, donor cells can be tracked and a portion of mice can be sacrificed at intervals after infusion to examine the number and function of E7-specific T cells.
[0304] The same experiment is repeated using CB6 F1 donors and B6C3 F1 recipients.
[0305] Example 3. Comparison of different E7 vaccines as immunogens for non-transplant donor lymphocyte infusions The objective of the study was to determine the optimal vaccine to induce E6 / E7-specific Th1 CD4+ T cells and enhance the antitumor effect of CD8-depleted donor lymphocyte infusion.
[0306] First, we characterize the effect of one, two, and three doses of the vaccine on CD4 + T cell responses to human papillomavirus type 16 (HPV16) E6 / E7 antigens.
[0307] Nine BALB / cx B6 mice in each group are vaccinated once, twice or three times weekly with either the RNA-LPX mRNA vaccine, PDS0101 or PapiVax DNA vaccine. One week after each vaccination, three mice from each group are sacrificed. Either splenocytes or vaccine-draining lymph node cells are stimulated with either HPV16 E6 overlapping peptides (JPT Peptides, Germany) or E7 overlapping peptides. Six hours after stimulation, extracellular CD4 and CD8 and intracellular interferon gamma (IFN-γ) and tumor necrosis factor alpha (TNF-a) are stained and analyzed by flow cytometry. Table 3 shows the drugs and treatment protocol of this study.
[0308] [Table 3]
[0309] Next, we will evaluate the antitumor effect of non-transplant cell therapy using donors vaccinated with either RNA-LPX, PDS0101 or PapiVax vaccine. Table 4 shows the drugs and treatment protocol of this study.
[0310] [Table 4]
[0311] Mice are photographed weekly to follow their survival.
[0312] Once the optimal vaccine is identified, a decision will be made whether to add recipient vaccination to donor vaccination. Table 5 lists the drugs and treatment protocol for this study.
[0313] [Table 5]
[0314] Example 4. CRISPR-mediated excision of selected genes in donor CD4+ T cells The aim of this study is to prevent the conversion of T cells to regulatory T cells in vivo. h The goal of this study is to test CRISPR-mediated ablation of selected genes in donor CD4+ T cells as a means to polarize the tumor-specific CD4+ T cells toward the 1 pathway and enhance the antitumor efficacy of nontransplant donor lymphocyte infusions. Table 6 shows the drugs and treatment protocol of this study.
[0315] [Table 6]
[0316] For each of groups 2-7, BTK and ITK activity after inhibition will be assayed by measuring the amount of phospho-BTK or phospho-ITK protein after CD3 / CD28 stimulation (see J. Dubovsky et al. Blood 122: 2539, 2013). The frequency of IL-4 vs. IFN-γ producing CD4+ T cells will be measured by intracellular cytokine staining and flow cytometry.
[0317] Example 5. E7-specific CD4 + To compare in vivo priming against E7 with or without ex vivo restimulation to pure ex vivo priming and restimulation to generate and expand Th1 cells and enhance the antitumor effect of nontransplant donor lymphocyte infusion The aim of this study is to determine whether donor vaccination can be eliminated from the protocol.
[0318] A. Donor Cell Preparation CB6 F1 donor mice or splenocytes are treated as shown in Table 7 below.
[0319] [Table 7]
[0320] For in vivo priming or boosting, 25 μg of pcDNA3-CRT / E7 is administered intramuscularly.
[0321] B. Ex vivo priming or boosting Murine dendritic cells (DCs) are enriched using a mouse pan-dendritic cell isolation kit (Miltenyi Biotech). DCs are pulsed with 1 μg / mL E7 peptide (JPT Peptide Technologies) for 2 h in RPMI1640 (complete medium) containing 2 mmol / L L-glutamine, 100 U / mL penicillin, 100 μg / mL streptomycin, and 10% heat-inactivated fetal bovine serum. E7-pulsed DCs are then transferred to flasks containing mouse splenocytes (treated with 1 μM ITK inhibitor for 1 h before mixing) in a 1:20 ratio with complete medium containing 25 U / mL recombinant mouse IL-2 and 20 ng / mL recombinant mouse GMCSF and cultured for 5 days. Cells are then washed and rested for 2 days in complete medium + IL-2 and GM-CSF before restimulation. Table 8 shows the drugs and treatment protocol for this study.
[0322] [Table 8]
[0323] On day 15, the frequency of E7-specific Th1 cells among all donor cells in groups 2-7 is determined by intracellular cytokine staining and flow cytometry. Mouse splenocytes are stimulated for 5 hours in complete medium with 1 μg / mL E7 peptide and with or without 5 μg / mL Brefeldin A. Cells are then washed and stained for IFN-γ and TNF-α along with CD4 and CD8.
[0324] Example 6. Anti-lymphoma effect of CD8-depleted donor lymphocyte infusion. + Effect of ITK deletion alone or in combination with BTK deletion in T cells The purpose of this study was to identify donor strains and their T h 1 (e.g., C57BL / 6) or T hThe objective of this study is to verify whether the bias towards BALB / c (e.g., BALB / c) affects the antitumor immunity of CD8-depleted DLI and its enhancement by BTK or ITK deletion in donor CD4+ T cells. Table 9 shows the tumor types, lineages of origin, and donor lineages in this study.
[0325] [Table 9]
[0326] The experimental design was the same for all three tumor types, with only differences in tumor dose and donor and recipient strains. Table 10 shows the treatment protocol for this study.
[0327] [Table 10]
[0328] Example 7. Efficacy of non-transplant donor lymphocyte infusion for common malignant tumors (lung, breast, ovarian) The aim of this study is to test whether non-transplant DLI can be incorporated into the treatment of common malignancies and be synergistic with checkpoint blockade. The cancers being studied are lung, breast and ovarian cancers.
[0329] A. Lung cancer
[0330] Tables 11 and 12 show the treatment protocols for lung cancer studies.
[0331] [Table 11]
[0332] [Table 12]
[0333] B. Breast cancer Table 13 shows the treatment protocols for breast cancer studies.
[0334] [Table 13]
[0335] C. Ovarian cancer Table 14 shows the treatment protocols for breast cancer studies.
[0336] [Table 14]
[0337] Example 8. Effect of donor neoantigen vaccination on the antitumor efficacy of CD8-depleted non-transplanted DLI against neoantigen-expressing tumors The aim of this study was to test whether a donor vaccine strategy could be employed for the treatment of sporadic tumors through vaccination against tumor neoantigens.
[0338] In this experiment, we test two methods to increase the frequency of neoAg-specific CD4+ T cells in CD8-depleted NEDLI: 1) in vivo vaccination with CD4+ T cell neoepitopes (with or without subsequent neopeptide stimulation); or 2) in vitro "priming" with sequential stimulation of CD4+ T cells with neopeptide+DCs. The experimental design is shown in Table 15 below.
[0339] [Table 15]
[0340] B16-F10 melanomas derived from C57BL / 6 (B6; H-2b) are grown in F1 hybrids; immunogenic CD4+ neoepitopes have been identified (see reference 4). 1) B6 x C3H (B6C3; H-2bxk) F1 or MHC-haploidentical BALB / cx B6 (CB6; H-2bxd) F1 mice are vaccinated with either the mutant neoepitope M30 (groups 2, 6) encoded by the kinesin family member 18b gene (Kif18b) or the corresponding wild-type peptide (groups 1, 5) by injecting a vaccine containing 100 μg of synthetic peptide and 50 μg of poly(I:C) in a volume of 200 μL phosphate-buffered saline into the flank. Vaccination efficacy and responder cell phenotype (CD4 vs. CD8) will be examined by flow cytometry and intracellular cytokine staining (ICS) for interferon gamma (IFNγ) or tumor necrosis factor alpha (TNF-α) as described in reference 5. Two weeks after vaccination, CD8+ cells will be removed from the spleen of euthanized donor mice and infused into B16-F10 bearing B6C3 mice treated with Cy the day before infusion.
[0341] Alternatively, CD8-depleted cells from immunized donors are cultured for 5 days with M30-pulsed donor DCs 5 days prior to infusion (groups 3, 7); 2) spleen cells from naive B6C3 or CB6 F1 mice are stimulated twice weekly with M30-pulsed autologous dendritic cells + 20 U / mL IL-2 (groups 4, 8). The frequency of M30-specific IFNγ+CD4+T cells is measured by ICS before and after ex vivo stimulation. NeoAg-specific CD4+T cells can be purified using an IFNγ capture assay (Miltenyi Biotec) and further expanded using anti-CD3 and anti-CD28 coated beads.

[0343] Example 9. Depletion of CD8+ T cells CD8+ T cells are removed from human blood products using the CliniMACS system with CliniMACS® CD8 Reagent. CD8+ T cells are labeled with monoclonal antibodies bound to superparamagnetic particles and removed from the blood product by passing them through the CliniMACS system, which incorporates a separation column with a strong permanent magnet and a ferromagnetic matrix to remove the labeled cells.
[0344] Example 10. Differential effects of single gene deletions on the antitumor efficacy of CD4+ T cells from MHC haploidentical donors vaccinated against tumor antigens Previous experiments demonstrated that prior vaccination of healthy donors against a tumor antigen (E7 of human papillomavirus type 16 [HPV16]) enhanced the antitumor efficacy of donor CD8-depleted lymphocytes infused after cyclophosphamide treatment of MHC haploidentical recipients with advanced E7-expressing tumors. CD4+ T cells from vaccinated donors slightly extended the survival of tumor-bearing recipients, but all recipients eventually succumbed to progressive tumors. See US, Publication No: 2022 / 0163997.
[0345] It has been hypothesized that growing tumors eventually polarize infused CD4+ T cells to render them ineffective at providing antitumor immune help, but deleting key genes involved in CD4+ T cell differentiation / polarization may prevent this loss of CD4+ T cell help and thereby sustain antitumor immune responses.
[0346] To test this hypothesis, BALB / cx C57BL / 6 (CB6 F1) donors were vaccinated three times a week with 25 micrograms of pBI-11, a DNA vaccine encoding the E6 and E7 antigens of HPV16, intramuscularly. One week after the third vaccination, CD4+ T cells were enriched to near purity using immunomagnetic beads and either left untreated, transfected with Cas9 nucleoprotein, or transfected with Cas9 nucleoprotein and guide RNA to inactivate single genes: interleukin-2-inducible T cell kinase (ITK), forkhead box p3 (FOXP3), transforming growth factor beta receptor type II (TGFBR2), suppressor of cytokine signaling-1 (SOCS1), or programmed death molecule-1 (PDCD1). After resting the cells overnight, 25 million unvaccinated, vaccinated but non-nucleofected, vaccinated and Cas9-nucleofected, or single gene-deficient CD4+ T cells were co-injected with 5 million syngenic (CB6 F1) CD3-depleted splenocytes into MHC haploidentical C57BL / 6 x C3H (B6C3 F1) mice that had received 50,000 TC-1 tumor cells (expressing HPV16 E6 and E7) 14 days prior to infusion and 200 mg / kg cyclophosphamide intraperitoneally the day prior to infusion. See Figure 1.
[0347] Donor vaccination against HPV E7 enhanced the antitumor effect of cyclophosphamide CD8-depleted, MHC haploidentical donor lymphocyte infusion, with the difference in tumor-free survival between TC1-luci-bearing recipients of unvaccinated and TC1-luci-bearing recipients of vaccinated donor cells approaching statistical significance by day 42 post-tumor inoculation (p=0.096; Figure 2A). Nucleofection with Cas9 reagent, but not gene knockout, did not significantly affect tumor-free survival in donor lymphocyte infusion recipients (Figure 2B; p=0.99). In contrast, CRISPR-mediated deletion of the ITK gene in donor CD4+ T cells further increased tumor-free survival compared to recipients of vaccinated CD4+ T cells without ITK deletion (p=0.17) or recipients of CD4+ T cells from unvaccinated donors (p~0.07; Figure 2C). Different single gene deletions in CD4+ T cells of E6 / E7 vaccinated donors had different effects on DLI-induced antitumor immunity (Figure 2D). Interestingly, tumor-bearing recipients of vaccinated CD4+ T cells containing deletions of either PD-1 or TGFβR2 had slightly worse tumor-free survival than recipients of genetically unmodified CD4+ T cells and significantly worse overall survival than recipients of cells with deletions of either ITK or foxp3 (Figure 2D and Table 16).
[0348] [Table 16]
[0349] These results indicate that CRISPR-mediated deletion of genes involved in CD4+ T cell differentiation and function may affect the antitumor efficacy of cell therapy from healthy donors vaccinated against tumor antigens.-Deletion of ITK or FOXP3 appears to be beneficial, whereas deletion of PDCD1 or TGFBR2 results in poorer tumor-free survival compared to genetically unmodified CD4+ T cells.
[0350] Example 11. Additional gene deletions for antitumor efficacy of CD4+ T cells from MHC haploidentical donors vaccinated against tumor antigens BALB / cx C57BL / 6 (CB6 F1) donors are vaccinated three times a week with intramuscular injections of 25 micrograms of pBI-11, a DNA vaccine encoding the E6 and E7 antigens of HPV16. One week after the third vaccination, CD4+ T cells are enriched to near purity using immunomagnetic beads and either left untreated, transfected with Cas9 nucleoprotein, or transfected with Cas9 nucleoprotein and guide RNAs to inactivate single genes: Bruton's tyrosine kinase (BTK), delta isoform of phosphoinositide 3 kinase (PI3Kδ), helios, blimp1, GATA3, IL-10, STAT3, TOX, CD25, Ezh2, LAG-3, TNF-α, or combinations thereof. After resting the cells overnight, 3 million unvaccinated, vaccinated but non-nucleofected, vaccinated and Cas9-nucleofected CD4+ T cells, or single gene-deficient CD4+ T cells are co-injected with 5 million syngenic (CB6 F1) CD3-deleted splenocytes into MHC haploidentical C57BL / 6 x C3H (B6C3 F1) mice that had been administered 50,000 TC-1 tumor cells (expressing HPV16 E6 and E7) 14 days prior to infusion and 200 mg / kg cyclophosphamide intraperitoneally the day prior to infusion.
[0351] Example 12. Combination of gene deletions on the antitumor effect of CD4+ T cells from MHC haploidentical donors vaccinated against tumor antigens
[0352] BALB / cx C57BL / 6 (CB6 F1) donors are vaccinated three times a week with intramuscular injections of 25 micrograms of pBI-11, a DNA vaccine encoding the E6 and E7 antigens of HPV16. One week after the third vaccination, CD4+ T cells are enriched to near purity using immunomagnetic beads and either left untreated, transfected with Cas9 nuclear protein, or transfected with Cas9 nuclear protein and guide RNA to inactivate a combination of two or more genes: Bruton's tyrosine kinase (BTK), interleukin-2-inducible T cell kinase (ITK), phosphoinositide 3 kinase delta isoform (PI3Kδ), helios, blimp1, SOCS1, GATA3, IL-10, STAT3, TGF-β receptor II, LAG-3, PD-1, TNF-α, TOX, CD25, foxp3, and Ezh2. After resting the cells overnight, 3 million unvaccinated, vaccinated but non-nucleofected, vaccinated and Cas9-nucleofected, or single gene-deficient CD4+ T cells are infused together with 5 million syngenic (CB6 F1) CD3-deleted splenocytes into MHC haploidentical C57BL / 6 x C3H (B6C3 F1) mice that received 50,000 TC-1 tumor cells (expressing HPV16 E6 and E7) 14 days prior to infusion and 200 mg / kg cyclophosphamide intraperitoneally the day before infusion.
