Field

[01] This disclosure pertains to methods of treating cancer and lymphocyte mediated diseases using Intercellular Adhesion Molecule (ICAM)-modulating agents. More specifically, the disclosure pertains to methods of treating cancer using high dose glucocorticoids such as dexamethasone.

Background

[02] Reducing cytotoxic chemotherapy use is a top priority goal of the National Cancer Institute. Chimeric antigen receptor (CAR) T-cell therapy has shown remarkable success in the treatment of CD- 19-expressing B-cell acute lymphocytic leukemia. However, there are a number of obstacles that limit CAR T-cell therapy for solid tumors: ineffective trafficking to the tumor as well immunosuppressive microenvironments in solid tumors limit T-cell efficacy. In addition, CAR T therapies have been associated with serious adverse effects, including cytokine release syndrome (CRS), neuroedema, and graft versus host disease (GvHD).

[03] Despite efforts to reduce the toxicities associated with cancer treatments, the physical toll and medical costs to manage these toxicities remain a significant concern. For example, up to 41% of blood cancer patients choose to stop taking the new kinase/proteasome inhibitors or biologies due to the physical and financial toxicities associated with these drugs (Mato 2018, Kadri 2017, Mato 2016 and Barrett 2010, each of which is hereby incorporated by reference in its entirety).

[04] Adhesion molecules are glycoproteins expressed on cell surfaces, which mediate the contact between two cells (both homotypic and heterotypic interactions) or between cells and the extracellular matrix (Hua 2013, which is hereby incorporated by reference in its entirety). ICAMs are type I transmembrane glycoproteins of the immunoglobulin superfamily, which are ligands for antigens expressed on the surface of immune cells, such as leukocyte integrins. The five known ICAM family members (ICAM1-ICAM5) are known to play a role in inflammation, immune responses, and intracellular signalling (Shen et al 2018 which is hereby incorporated by reference in its entirety).

[05] Of the five ICAMs identified, ICAM-1 (Intercellular Adhesion Molecule 1; also known as CD54) is the most extensively studied (Hua et al, 2013). ICAM-1 is expressed on many cell types including endothelial cells and different cancer cell entities. Experimental data indicate that ICAM-1 can activate intracellular signaling pathways in cancer cells leading to enhanced cell motility, invasion and metastasis (Schroder at el 2011 which is hereby incorporated by reference in its entirety).

[06] ICAM-3 (also known as CD50) is expressed by lymphocytes, monocytes, eosinophils and neutrophils (as well as on bronchioles, and by lymphoma cells and some melanoma, sarcoma, and other cancer cells). Information on the underlying ICAM3 gene is available online, for instance on the Ensemble database; see entry ENSG00000076662. ICAM3- mediated signaling proceeds via recruitment of Src by the YLPL motif in the ICAM3 intracellular domain leading to PI3K-AKT phosphorylation cascades (Shen et al, 2018). ICAM3 is one of the most heavily Asp-glycosylated proteins in the human body. Asparagine residues (Asp) become decorated with glycans linked at the nitrogen of the amide side group. This is a biologically important posttranslational modification that begins in the endoplasmic reticulum with the transfer of a core glycan comprising three mannose subunits.

[07] Shen et al (2018) have reported ICAM3 involvement in cancer cell sternness in vitro and in vivo. ICAM3 expression on eosinophils is decreased by exposure to modest concentrations of dexamethasone (100 pM to 1 mM) (Juan et al, 1999, which is hereby incorporated by reference in its entirety). Glycosylation of ICAM3 can be reduced when cells are used ex vivo or on in vitro cell lines, resulting in disparate in vivo versus ex vivo or in vitro effects of ICAM3 activation or inhibition.

[08] ICAM4 was originally named the ‘LW glycoprotein’ and its expression was thought to be largely restricted to red blood cells, although more recent studies have shown it to be expressed also by macrophages (Choi et al, 2017, which is hereby incorporated by reference in its entirety). Information on the underlying ICAM4 gene is available online, for instance on the Ensemble database; see entry ENSG00000105371.

[09] The present authors have previously found that high concentrations of glucocorticoids could be used to condition patients to enhance the efficacy of cellular immunotherapies such as adoptive T cell therapy; described in International patent application PCT/US2018/025517 (published as WO2018/183927). In that application, the authors noted the toxicities associated with chemotherapy and radiation mediated preconditioning, which is believed to non- selectively destroy the cellularity of the spleen. The authors provided glucocorticoids (a subclass of steroids) and other non-toxic lymphodepleting agents, at acute doses, to benefit cancer patients who receive cellular immunotherapies. [010] In international patent application PCT/US2019/054395 the present authors have also described the use of high concentrations of glucocorticoids to cause lymphodepletion of peripheral blood lymphocytes without substantially affecting the cell count of other cells. In that application, the authors reported that high concentrations of glucocorticoids can deplete peripheral blood lymphocytes including, for example, islet-specific autoreactive T-cells responsible for diabetes autoimmunity, but spares neutrophils, platelets, RBCs and stem cells (both HSCs and MSCs). The authors provided glucocorticoids as a non-myeloablative regimen that can perform a safe immunologic reset with efficacy comparable to chemotherapy.

[Oil] A need exists for further treatments for cancer that are safer and associated with fewer toxicities and / or greater efficacy than currently available therapies. Treatments that are simpler, less toxic, and less costly are desired.

Summary

[012] The present disclosure is based on the surprising finding that, following high dose administration, glucocorticoid molecules can bind and block intercellular adhesion molecules such as ICAM3. The binding is cooperative and up to 26 molecules bind the first Ig domain of ICAM3. When administered at high doses, glucocorticoids may be ‘soaked up’ by ICAM3, which is expressed at substantial levels on cells such as lymphocytes, monocytes and neutrophils, as well as on cancer cell types such as melanoma and osteosarcoma, resulting in concentration-dependent apoptosis of these ICAM3 expressing cells (see Examples 1 and 2). The authors have also demonstrated that at ex vivo or in vitro concentrations equal to the peak blood concentrations of HED of 15 mg/kg dexamethasone phosphate or greater that there is no direct apoptotic effect on whole blood or splenocytes, demonstrating that glucocorticoid receptors are not bound/activated at these high concentrations.

[013] Without being bound by theory, the authors believe that binding of glucocorticoids to ICAM3 can lead to the cell becoming marked for attack by other lymphocytes such as NKT cells and CD8+ T cells. ICAM3 shedding may also occur following glucocorticoid binding, further stimulating an immune response against these cell types.

[014] Accordingly, in a first aspect, the disclosure provides a method of treating cancer or a lymphocyte-mediated disease in a subject, the method comprising administering a therapeutically effective amount of a glucocorticoid to the subject, wherein the glucocorticoid induces cell death of ICAM3 expressing cells by binding to ICAM3.

Summary of the Figures

[029] Embodiments and experiments illustrating the principles of the disclosure will now be discussed with reference to the accompanying figures in which:

[030] Figure 1. 1 A: AVM0703 Receptor (ICAM3) protein expression levels in various organs from the Human Proteome Project. Expression is highly observed on hematopoietic / immune organs (all examined) and skin which contains high concentrations of immune cells. IB: From the Fantom5 Dataset, measuring ICAM3 RNA expression, lung expresses moderate levels of ICAM3. RNA is also expressed by multiple myeloid and lymphoid lineage cell lines, including HEL, HL-60, HMC-1, K-562, NB-4, THP-1, U-937, Daudi, HDLM-2, Laspas_707, MOLT-4, REH, RPMI-8226, U-266/70, U-266/84, and U-698 cell lines (data not shown).

[031] Figure 2. The AVM0703 Receptor (ICAM3) is widely expressed by lymphomas; strong expression was identified on 12 out of 12 tested lymphoma biopsies. ICAM3 is also detected at low levels on some biopsied colorectal cancer cells, weakly on some breast cancer biopsies of duct carcinoma, and on bronchiole like cells from lung cancer biopsies but not on the cancerous cells (data not shown). Protein expression from biopsy samples is from the Human Proteome Project.

[032] Figure 3. The AVM0703 Receptor (ICAM3) is expressed on pediatric cancers (from St. Jude’s Pediatric Cancer Genome Project). Cancers expressing ICAM3 mRNA levels above the median are all types of leukemias and lymphomas. There are some acute lymphocytic leukemia samples that express ICAM3 mRNA at levels below the median of all 1976 samples. All solid tumors had ICAM3 mRNA expression below the median.

[033] Figure 4. The AVM0703 Receptor (ICAM3) is expressed by U2 OS osteosarcoma cells (from the Human Proteome Project).

[034] Figure 5. PI staining of dead U2 osteosarcoma cells 24 hours after AVM0703 administration. AVM0703 induces in vitro apoptosis of U2 OS cells in a concentration- dependent manner. Dexamethasone base doses that induced apoptosis include 50, 100, 175, and 250 mM. U2 OS cells do not express the glucocorticoid receptor, demonstrating that activity is via activation/alteration of ICAM3.

[035] Figure 6. Splenocyte viability following 4 hours incubation with dexamethasone base (1 nM - 250 pM). At doses above 100 pM, AVM0703 no longer induces apoptosis of freshly isolated splenocytes, demonstrating that ex vivo at concentrations equivalent to peak plasma concentrations following a human equivalent dose (HED) of 15 mg/kg glucocorticoid receptors are not bound or activated.

Detailed Description

[036] Aspects and embodiments of the present disclosure will now be discussed with reference to the accompanying figures. Further aspects and embodiments will be apparent to those skilled in the art. All documents mentioned in this text are incorporated herein by reference.

[037] The present disclosure pertains to: methods of treating cancer or a lymphocyte- mediated disease in a subject, the method comprising administering a therapeutically effective amount of an ICAM3 modulating agent to the subject. The present disclosure also provides ICAM3 modulating agents (which may be a glucocorticoid, such as dexamethasone) for use in such methods, as well as the use of an ICAM3 modulating agent (which may be a glucocorticoid, such as dexamethasone) for the manufacture of a medicament for use in such methods.

Pharmacological action

[038] A receptor antagonist is a ligand that binds to the receptor, thus occupying the receptor binding site, but without activating the receptor. In contrast, a receptor agonist binds and activates the receptor, which typically causes a signal to be transduced within the cell. Therefore, antagonists can exert biologically relevant actions by competing with agonists, and other receptor-binding agents, for binding. Antagonists are therefore commonly referred to as ‘blockers’.

[039] The glucocorticoid modulating agents of the present disclosure typically act as agonists on glucocorticoid receptors. However, the present application discloses the surprising capacity of glucocorticoid modulating agents (such as dexamethasone and other glucocorticoids) to bind the Intracellular Adhesion Molecule 3 (ICAM3) and induce cell death / apoptosis of ICAM3 -expressing cells. Without being bound by theory, the authors believe that this apoptosis may be caused by one or more of: activation of ICAM3; triggering (activating) of cell apoptotic pathways; binding of ICAM3 leading to the cells being marked for attack by macrophages and / or leukocytes such as NKT cells and CD8+ T cells; and, shedding of ICAM3 from the cell surface.

ICAM-3 modulating agent

[040] ICAM3 modulating agents in the context of the present disclosure are those which bind ICAM3 and promote the concentration dependent apoptotic cell death demonstrated in the Examples. That is, without being bound by theory, such agents may bind ICAM3 and: block the signalling cascades caused by ICAM3 activation; activate signalling cascades to induce cell-mediated apoptosis; cause the ICAM3 expressing cell to become marked for attack by macrophages or lymphocytes such as NKT cells and CD8+ T cells; and / or, cause ICAM3 shedding from the surface of the ICAM3 expressing cell. The ICAM3 modulating agent may be an ICAM3 antagonist / ICAM3 inhibitor, or may be an ICAM3 agonist / activator. [041] Such ICAM3 modulating agents may include, for example, anti-ICAM3 antibodies raised against ICAM3 or a portion thereof, small molecule modulators of ICAM3 (such as activators or inhibitors of ICAM3), and peptide agents / proteins which bind ICAM3.

Suitable means of identifying ICAM3 modulating agents will be well known to those of skill in the art - for example, anti ICAM3 antibodies may be identified by a method which may include bringing into contact a library of antibody molecules and an ICAM3 epitope, and selecting one or more specific antibody molecules of the library able to bind said epitope. Alternatively, these could be identified using competition binding assays employing known anti ICAM3 antibodies, with competition determined, for example, using ELISA or flow cytometry. Similarly, small molecule modulators of ICAM3 may be identified by routine screening experiments such as radioligand binding assays and functional assays.

[042] As already described above, the present application discloses the surprising capacity of glucocorticoid receptor modulating agents (such as dexamethasone and other glucocorticoids) to bind ICAM3 and exert modulating actions upon ICAM3. Thus, in some embodiments, the ICAM3 modulating agent may be a glucocorticoid-receptor (GR) modulating agent. As used herein, the term glucocorticoid-receptor (GR) modulating agent includes glucocorticoids, glucocorticoid receptor agonists, and any compound that binds to the glucocorticoid receptor. Glucocorticoid-receptor (GR) modulating agents such as glucocorticoids exert their effects through both membrane GRs and cytoplasmic GRs which activate or repress gene expression. Some of the desirable lymphodepletive effects of glucocorticoids and GR modulating agents are believed to be mediated via membrane GRs or other non-genomic effects in addition to their genomic effects. Glucocorticoids have been reported to have varied effects on lymphocyte levels, depending on the concentration of the glucocorticoid administered and the duration of treatment. In general, at low doses typically used for chronic therapy, glucocorticoids have been reported to redistribute lymphocytes from the peripheral blood into the bone marrow, at medium doses glucocorticoids have been reported to cause leukocytosis thought to be a redistribution of leukocytes from the bone marrow, spleen and thymus into the peripheral blood, and at high doses glucocorticoids have a lymphotoxic action on lymphocytes by triggering apoptosis and necroptosis. The duration of effect also depends on the dose level; for instance Fauci et al (1916) reports a single oral 0.24 mg/kg dexamethasone dose suppresses peripheral blood T and B lymphocytes 80% with recovery beginning at 12 hours and normal levels by 24 hours. The present authors have previously demonstrated (in international patent application PCT/US2019/054395) that acute oral doses of 3 mg/kg or greater dexamethasone are necessary to reduce peripheral blood T and B cells 24-48 hours after administration, with return to baseline levels occurring around 5 to 14 days after dosing.

[043] Glucocorticoid-receptor (GR) modulating agents which may be used in the disclosed methods include, for example, selective glucocorticoid receptor modulators (SEGRMs) and selective glucocorticoid receptor agonists (SEGRAs). Glucocorticoids, selective glucocorticoid receptor modulators, and selective glucocorticoid receptor agonists (SEGRAs) that may be utilized in the disclosed methods are well known to those skilled in the art.

[044] Some such glucocorticoids include, but are not limited to, dexamethasone, dexamethasone containing agents, hydrocortisone, methylpredisone, prednisone, corticone, budesonide, betamethasone, ciclesonide, and beclomethasone. Other glucocorticoids include prednisolone, mometasone furoate, Triamcinolone Acetonide, and methylprednisolone.

[045] Accordingly, in some preferred embodiments of the methods of the disclosure, the glucocorticoid-receptor (GR) modulating agent may be a glucocorticoid. In some such embodiments, the glucocorticoid may be selected from the group consisting of: dexamethasone, hydrocortisone, methylprednisolone, prednisone, prednisolone, prednylidene, cortisone, budesonide, betamethasone, flumethasone, ciclesonide, and beclomethasone. In some preferred embodiments, the glucocorticoid may be selected from the group consisting of: dexamethasone, betamethasone, and methylprednisone. In some particularly preferred embodiments the glucocorticoid may be dexamethasone or betamethasone.

[046] In some embodiments of the methods of the disclosure, the glucocorticoid may be selected from the group consisting of: dexamethasone base, dexamethasone sodium phosphate, dexamethasone hemi succinate, dexamethasone sodium succinate, dexamethasone succinate, dexamethasone isonicotinate, dexamethasone-21 -acetate, dexamethasone phosphate, dexamethasone-21 -phosphate, dexamethasone tebutate, dexamethasone- 17- valerate, dexamethasone acetate monohydrate, dexamethasone pivalate, dexamethasone palmitate, dexamethasone-21 -palmitate, dexamethasone dipropionate, dexamethasone propionate, dexamethasone acetate anhydrous, dexamethasone-21 -phenylpropionate, dexamethasone-21 -sulfobenzoate, dexamethasone hemo-sulfate, dexamethasone sulfate, dexamethasone beloxil, dexamethasone acid, dexamethasone acefurate, dexamethasone carboximide, dexamethasone cipecilate, dexamethasone 21 -phosphate disodium salt, dexamethasone mesylate, dexamethasone linoleate, dexamethasone glucoside, dexamethasone glucuronide, dexamethasone iodoacetate, dexamethasone oxetanone, carboxymethylthio-dexamethasone, dexamethasonebisethoximes, dexamethasone epoxide, dexamethasonelinolelaidate, dexamethasone methylorthovalerate, dexamethasone spermine, 6-hydroxy dexamethasone, dexamethasone tributyl acetate, dexamethasone aspartic acid, dexamethasone galactopyranose, dexamethasone hydrochloride, hydroxy dexamethasone , carboxy dexamethasone, desoxy dexamethasone, dexamethasone butazone, dexamethasone cyclodextrin, dihydro dexamethasone, oxo dexamethasone, propionyloxy dexamethasone, dexamethasone galactodie, dexamethasone isonicotinate, dexamethasone sodium hydrogen phosphate, dexamethasone aldehyde, dexamethasone pivlate, dexamethasone tridecylate, dexamethasone crotonate, dexamethasone methanesulfonate, dexamethasone butylacetate, dehydro dexamethasone, dexamethasone Isothiocyanatoethyl)Thioether, dexamethasone bromoacetate, dexamethasone hemiglutarate, deoxy dexamethasone, dexamethasone chlorambucilate, dexamethasone melphalanate, formyloxy dexamethasone, dexamethasone butyrate, dexamethasone laurate, dexamethasone acetate, and any combination treatment that contains a form of dexamethasone. In some preferred embodiments, the glucocorticoid may be dexamethasone base or dexamethasone sodium phosphate.

[047] In some embodiments of the disclosure, the glucocorticoid receptor modulating agent may not be one or more of the above recited agents.

Mechanism

[048] In the Examples, the authors have shown that glucocorticoid molecules can bind intercellular adhesion molecules such as ICAM3 which is highly expressed on lymphocytes, monocytes and neutrophils, as well as on cancer cell types such as melanoma and osteosarcoma. By binding ICAM3, high dose glucocorticoids are able to exert a concentration dependent, direct killing effect on these cell types.

[049] Accordingly, in the methods of the disclosure, the ICAM3 modulating agents induce cell death of ICAM3 expressing cells by binding to ICAM3. In some embodiments, the ICAM3 modulating agents induce apoptosis of ICAM3 expressing cells by binding to ICAM3. In some embodiments, the ICAM3 modulating agent triggers or supports an effective immune response against the ICAM3 expressing cells. In some embodiments, the ICAM3 modulating agent causes ICAM3 shedding from the surface of a cell into the extracellular space. In some embodiments, the ICAM3 modulating agent causes ICAM3 expressing cells to be marked for attack by immune cells. In some embodiments the ICAM3 modulating agent triggers (activates) cell apoptotic pathways. [050] In some embodiments, ICAM3 is the amino acid disclosed at UniProt accession no: P32942 (entry version 198) or a fragment thereof. In some embodiments, ICAM3 comprises an amino acid sequence having at least 70%, 80%, 90%, 95%, 99% or 100% sequence identity with the full-length of the amino acid sequence disclosed at UniProt accession no P32942 (entry version 198).

Biological action by marking cells for immune attack

[051] Monocytes and macrophages are phagocytic white blood cells which act in both non specific and specific defense mechanisms in vertebrates. Their role is to phagocytose (engulf and then digest) dead and dying cells, cellular debris and pathogens either as stationary or as mobile cells, and to stimulate lymphocytes and other immune cells to respond to the pathogen. The molecular mechanisms underlying recruitment of phagocytic white blood cells is believed to involve recognition of molecular ‘flags’ on the surface of dying cell, that are bound and allow the dying cell to be eaten and destroyed (Gregory & Pound, 2010, hereby incorporated by reference in its entirety). ICAM3 has been shown to act as such a molecular ‘flag’ following a change of function on dying cells (Moffat et el 1999, hereby incorporated by reference in its entirety).

[052] Thus, without being bound by theory, the present authors believe that the concentration-dependent mechanism of cell apoptosis observed following in vitro administration of acute high dose glucocorticoids (see Examples 1 and 2) may be mediated by binding of glucocorticoids to ICAM3 causing the ICAM3 expressing cells to become marked for attack by macrophages and / or leukocytes such as NKT cells and CD8+ T cells. These may include the immune cells that the present authors have shown are induced / mobilised by high concentrations of glucocorticoids, as described more fully below.

[053] ICAM3 shedding may also occur following glucocorticoid binding: Juan, 1999,

(which is hereby incorporated by reference in its entirety) describes that, after 24 hours, dexamethasone from 0.1 nanomolar up to 1 micromolar induced shedding of up to 28-33% of ICAM3 from eosinophils. The shedding described in Juan was near maximal (28%) at 0.01 micromolar: adding two logs additional dexamethasone elicited only modest further increases in shedding to 28% (+5%), which would not have motivated experts in the field to investigate higher concentrations of dexamethasone to determine further effects on ICAM3 shedding. ICAM3 shedding following glucocorticoid binding may further stimulate an immune response against these cell types by acting as a chemoattractant signal promoting recruitment of macrophages / phagocytes to the site of cells from which ICAM3 has been shed (described, for example, in Torr et al 2012, hereby incorporated by reference in its entirety). Cells recruited to the site of cells from which ICAM3 has been shed may include the immune cells that the present authors have shown are induced / mobilised by high concentrations of glucocorticoids, as described more fully below. The present authors hypothesize that ICAM3 shedding following dexamethasone binding may contribute to mobilisation of these novel immune cells after supra-high concentrations of glucocorticoids.

[054] Thus, in some embodiments of the methods of the disclosure, the ICAM3 modulating agent causes ICAM3 shedding from the surface of a cell into the extracellular space. In some embodiments, at least about 10, 20, 30, 35, 40, 45 50, 55, 60, 65, 70, 75 80, 85, 90, 95, 96,

97, 98, 99, or 99% of the total ICAM3 expressed by a cell is shed into the extracellular space. In some embodiments, the ICAM3 elicits at least about a 10, 20, 30, 35, 40, 45, 50, 55, 60,

65, 70, 75 80, 85, 90, 95, 96, 97, 98, 99, or 99% reduction in surface expression of ICAM3 on a cell. In some preferred embodiments, at least about 30 or 40% of the total ICAM3 expressed by a cell is shed into the extracellular space. In some preferred embodiments, the ICAM3 elicits at least about a 35 or 40% reduction in surface expression of ICAM3 on a cell. Suitable methods for determining extent and changes in ICAM3 expression and shedding are well known to those of skill in the art, for example the methods described in Juan et al (which is hereby incorporated by reference in its entirety).

Biological action via induction of immune cells

[055] High doses of glucocorticoid exert powerful biological effects that will contribute to the treatment of lymphocyte-mediated diseases and cancers. AVM0703 at human-equivalent dose (HED doses) of 15 mg/kg and above mobilizes a very active Natural Killer T cell that expresses CD3 at very high levels (AVM_NKT cells), which are not otherwise found in the circulation without this high dose treatment. This cell type is discussed in greater detail below.

[056] At HED of 15 mg/kg dexamethasone phosphate and higher, besides mobilizing the abovementioned AVM NKT cells, novel CD3-very-high T cell (which may express both CD4 and CD8), and CD 1 lb-very-high dendritic cells are also induced. CD4CD8 double positivity on CD3 T lymphocytes indicates a cytotoxic T cell. Surprisingly, these doses of glucocorticoid do not appear to activate GRs because they have no activity at equivalent concentrations in vitro on whole blood or splenocytes (see Example 3, below), and in vivo there have been no effects on colon, pancreas or bone, which would be expected if GRs were being activated. In vivo only lymphocytes, monocytes, some neutrophils and cancer cells have been ablated. Almost complete ablation is seen just 6 hours after dexamethasone dosing, demonstrating a rapid onset of action.

[057] AVM NKT cells are NKp46+ and Ly6G positive, indicating the potential to directly kill targets as well as to engulf them. The typical AVM NKT summarized above are not CD Id restricted. CD1 lb very high dendritic cells are also activated by these doses of AVM0703. In vivo , glucocorticoids ablate lymphocytes other than NK and NKT cells, and monocytes, within 6 hours after oral dosing of naive mice. In tumor models the novel NKT and T cell are not observed in the blood. However, within 48 hours of dosing NKp46+ cells and Ly6G+ cells, which are not macrophages as they are negative for F4/80, can be found in formations within the tumors, surrounding regions of remaining viable tumor. This indicates the functional potency of these cells. In the tumor setting, the AVM novel immune cells are not observed in the blood. They appear to preferentially home to the abnormal cells, in this case cancer cells, and circulating normal monocytes and neutrophils are not depleted as they are in the naive setting.

[058] Beyond the known properties of NKT cells and the advantages of NKT cell-targeted immunotherapy, the novel AVM NKT cells offer an additional advantage as they may add direct target cell engulfment to the known killing properties of other NKT like invariant NKT (iNKT) cells. This function is attributed to the AVM NKT's unique expression of Ly6G. Moreover, the AVM NKT are induced by high dose glucocorticoids and are thus, in principle, available in large numbers, in contrast to the limited numbers of natural NKT (and iNKT cells) that are insufficient for autologous therapy in the elderly, the ill, or cancer patients.

Dosages

[059] In some embodiments of the methods of the disclosure, the ICAM3 modulating agent may be administered at a dose sufficient to block the signalling cascades caused by ICAM3 activation. In some embodiments of the methods of the disclosure, the ICAM3 modulating agent may be administered at a dose sufficient to activate the signalling cascades caused by ICAM3 activation. In some embodiments, the ICAM3 modulating agent is administered at a dose sufficient to cause ICAM3 shedding from the surface of a cell into the extracellular space. In some embodiments, the ICAM3 modulating agent is administered at a dose sufficient to cause ICAM3 expressing cells to be marked for attack by immune cells.

[060] In embodiments of the methods of the disclosure in which the ICAM3 modulating agent is a glucocorticoid-receptor (GR) modulating agent, the glucocorticoid-receptor (GR) modulating agent may be administered at a dose equivalent to about at least 6 mg/kg human equivalent dose (HED) of dexamethasone base.

[061] Equivalent doses of another glucocorticoid or glucocorticoid receptor modulating agent can be readily and easily calculated using publicly available corticoid conversion algorithms, preferably http://www.medcalc.com. By way of example, 3 to 12 mg/kg dexamethasone phosphate converts to 19 to 75 mg/kg prednisone. Since prednisone’s biologic half-life is about 20 hours, while dexamethasone’ s biologic half-life is about 36 to 54 hours prednisone would be dosed between 19 to 75 mg/kg every 24 hours for equivalent biologic dosing. More specifically, a 12 mg/kg dose of dexamethasone phosphate corresponds to a 75 mg/kg dose of prednisolone that would require repeat dosing of about two to about three doses every 24 hours. A lOmg/kg dose of betamethasone is about 12 mg/kg dexamethasone phosphate and has a pharmacodynamic (biologic) half-life similar to dexamethasone.

[062] Dexamethasone doses in the examples in the present application are given as human equivalent doses (HED). Methods for calculating the human equivalent dose (HED) are known in the art. For example the FDA’s Centre for Drug Evaluation and Research (CDER) issued a highly-cited guidance document in 2005 (U.S Department of Health CDER, 2005), which sets out the established algorithm for converting animal doses to HED based on body surface area (the generally accepted method for extrapolating doses between species) at Table 1 on page 7 of that document. For reference, Table 1 is reproduced below. The skilled person understands that the animal dose in mg/kg, explained below, the HED is calculated easily using the standard conversion factors in the right hand columns of Table 1:

Table 1: Conversion of Animal Doses to Human Equivalent Doses Based on Body Surface Area a Assumes 60 kg human. For species not listed or for weights outside the standard ranges,

HED can be calculated from the following formula:

HED = animal dose in mg/kg x (animal weight in kg/human weight in kg) ⁰³³ . b This k _m value is provided for reference only since healthy children will rarely be volunteers for phase 1 trials. cFor example, cynomolgus, rhesus, and stumptail.

[063] In some embodiments, the glucocorticoid-receptor (GR) modulating agent is administered at a dose equivalent to about at least 12 mg/kg human equivalent dose (HED) of dexamethasone base. In other preferred embodiments, the glucocorticoid-receptor (GR) modulating agent is administered at a dose equivalent to about at least 15 mg/kg human equivalent dose (HED) of dexamethasone base. In other preferred embodiments, the glucocorticoid-receptor (GR) modulating agent is administered at a dose equivalent to about at least 24 mg/kg human equivalent dose (HED) of dexamethasone base. In some preferred embodiments, the glucocorticoid-receptor (GR) modulating agent is administered at a dose equivalent to about 12 mg/kg human equivalent dose (HED) of dexamethasone base, about 15 mg/kg human equivalent dose (HED) of dexamethasone base, or about 18 mg/kg human equivalent dose (HED) of dexamethasone base, or about 24 mg/kg human equivalent dose (HED) of dexamethasone base, or about 30 mg/kg human equivalent dose (HED) of dexamethasone base, or about 45 mg/kg human equivalent dose (HED) of dexamethasone base.

[064] In some embodiments of the methods of the disclosure, the glucocorticoid-receptor (GR) modulating agent is administered at a dose equivalent to about at least 6-45 mg/kg human equivalent dose (HED) of dexamethasone base; about at least 15-24 mg/kg human equivalent dose (HED) of dexamethasone base; about at least 6-12 mg/kg human equivalent dose (HED) of dexamethasone base; or about at least 12-15 mg/kg human equivalent dose (HED) of dexamethasone base; or about at least 18-30 mg/kg human equivalent dose (HED) of dexamethasone base. [065] In the methods of the disclosure, the glucocorticoid-receptor (GR) modulating agent may be administered as a single acute dose, or as a total dose given over about a 24, 48, or 72 hour period. In some preferred embodiments, the glucocorticoid-receptor (GR) modulating agent is administered as a single acute dose. In other preferred embodiments, the glucocorticoid-receptor (GR) modulating agent is administered as a total dose given over about a 72 hour period.

[066] In some embodiments of the methods of the disclosure, the methods may comprise a step of administering one or more further doses of a glucocorticoid-receptor (GR) modulating agent to the subject.

[067] In this context, the one or more doses are administered further to a first or preceding dose of glucocorticoid-receptor (GR) modulating agent and may therefore be termed subsequent or second, third, fourth, etc. doses. Accordingly, in some embodiments, the one or more further doses may be administered about 24, 48, 72, 96, 120, 144, or 168 hours after a preceding dose (administration). In some embodiments, the one or more further doses may be administered every about 24, 48, 72, 96, 120, 144, or 168 hours after a preceding dose (administration). In some other embodiments, the one or more further doses may be administered once every week, once every two weeks, once every three weeks, or once every month after a preceding dose (administration). In some other embodiments, the one or more further doses may be administered twice every week after a preceding dose (administration). [068] In some embodiments, the one or more further doses may be administered between about 24 hours and 168 hours after a preceding dose (administration). In other embodiments, the one or more further doses may be administered between about 24 hours and 120 hours, between about 24 hours and 72 hours, or between about 24 hours and 48 hours after a preceding dose (administration). In some other embodiments, the one or more further doses may be administered between about 48 hours and 168 hours, between about 48 hours and 120 hours, or between about 48 hours and 72 hours after a preceding dose (administration). In some other embodiments, the one or more further doses may be administered between about 72 hours and 168 hours, or between about 72 hours and 120 hours after a preceding dose (administration).

[069] In some embodiments, a subsequent dose is given 7 days after the initial dose. In some embodiments, a subsequent dose is given 14 days after the initial dose. In some embodiments, a subsequent dose is given 21 days after the initial dose. [070] In some embodiments in which the subject has, is suspected of having, or has been diagnosed with a T cell lymphoma, the one or more further doses may be administered every 21 days, or every 14 days or every 5-7 days for a period of time that can be determined by a physician.

[071] In some embodiments in which the subject has, is suspected of having, or has been diagnosed with a B cell lymphoma, the one or more further doses may be administered every 21 days, or every 14 days or every 5-7 days for a period of time that can be determined by a physician.

Subjects

[072] The terms "subject" and "patient" are used interchangeably herein, and refer to a human or animal. In some embodiments of the methods of the disclosure, the subject may be mammalian. In some preferred embodiments, the subject may be human of any sex or race.

In some embodiments, the human is an adult human. In some embodiments of the methods of the disclosure, the subject may be a healthy subject, such as a healthy adult human subject. In this context a healthy subject is a subject which is not afflicted with disease.

[073] In some embodiments of the methods of the disclosure, the subject may have, be suspected of having, or have been diagnosed with a lymphocyte mediated disease or cancer.

Lymphocyte mediated disease

[074] The term "lymphocyte" as used herein includes natural killer (NK) cells, T cells, or B cells. NK cells are a type of cytotoxic (cell toxic) lymphocyte that represent a major component of the inherent immune system. NK cells reject tumors and cells infected by viruses. It works through the process of apoptosis or programmed cell death. They were termed "natural killers" because they do not require activation in order to kill cells. T-cells play a major role in cell-mediated-immunity (no antibody involvement). Its T-cell receptors (TCR) differentiate themselves from other lymphocyte types. The thymus, a specialized organ of the immune system, is primarily responsible for the T cell's maturation. There are six types of T-cells, namely: Helper T-cells (e.g., CD4+ cells), Cytotoxic T-cells (also known as TC, cytotoxic T lymphocyte, CTL, T-killer cell, cytolytic T cell, CDS+ T-cells or killer T cell), Memory T-cells ((i) stem memory T scM cells, like naive cells, are CD45RO-, CCR 7 +, CD45RA+, CD62L+(L-selectin), CD27+, CD28+ and IL-7Ra+, but they also express large amounts of CD95, IL-2R~, CXCR3, and LFA-1, and show numerous functional attributes distinctive of memory cells); (ii) central memory TcM cells express L-selectin and the CCR7, they secrete IL-2, but not IFNy or IL-4, and (iii) effector memory T EM cells, however, do not express L-selectin or CCR 7 but produce effector cytokines like IFNy and IL-4), Regulatory T-cells (Tregs, suppressor T cells, or CD4+CD25+ regulatory T cells), Natural Killer T-cells (NKT) and Gamma Delta T-cells. B-cells, on the other hand, play a principal role in humoral immunity (with antibody involvement). It makes antibodies and antigens and performs the role of antigen presenting cells (APCs) and turns into memory B-cells after activation by antigen interaction. In mammals, immature-cells are formed in the bone marrow, where its name is derived from.

Cell types

[094] Dendritic cells (DCs) are bone marrow-derived leukocytes, and are the most potent antigen-presenting cells of the mammalian immune system. DCs exert immune-surveillance for exogenous and endogenous antigens and the later activation of naive T lymphocytes giving rise to various immunological responses. DCs are sentinel cells responsible for the recognition of pathogens and signals of tissue damage, which induces their migration to lymphoid organs to carry out the activation of different subsets of T, natural killer (NK), NKT, and B lymphocytes. Mature phenotype cDC are characterized by an increase in MHCII, CD80, CD86, and CD40. Dendritic cells are frequently classified into conventional dendritic cell (cDC) and plasmacytoid dendritic cell (pDC) subsets. Dendritic cells exist primarily in two basic functional states: “immature” and “mature”. Activation (maturation) of dendritic cells turns on metabolic, cellular, and gene transcription programs allowing DC to migrate from peripheral tissues to T-dependent areas in secondary lymphoid organs, where T lymphocyte-activating antigen presentation may occur (Patente et al, 2018; hereby incorporated by reference in its entirety). The main function of dendritic cells is to process antigen material and present it on the cell surface to T cells thus initiating adaptive immune responses. Dendritic cells also produce polarizing cytokines that promote pathogen-specific effector T cell differentiation and activation, and can promote self-tolerance by secreting tolerogenic cytokines that induce the differentiation of regulatory T cells. The DCs induced by high dose glucocorticoids, and which may be induced by the methods of the disclosure may express CD1 lb to a very high level (“CD 1 lb-very -high dendritic cells”).

[095] T cells are a type of lymphocyte that play a key role in the immune response. T cells are distinguished from other types of lymphocytes by the presence of T-cell receptors on their cell surface. T-cell receptors (TCRs) are responsible for recognizing fragments of antigen bound to major histocompatibility complex (MHC) molecules, and are heterodimers of two different protein chains. In humans, in 95% of T cells the TCR consists of an alpha (a) chain and a beta (b) chain (encoded by TRA and TRB, respectively), whereas in 5% of T cells the TCR consists of gamma and delta (g/d) chains (encoded by TRG and TRD, respectively).

This ratio changes in diseased states (such as leukemia). In contrast to MHC-restricted alpha beta T cells, gamma delta T cells do not require antigen processing and major- histocompatibility-complex (MHC) presentation of peptide epitopes for activation, although some recognize MHC class lb molecules. Some gamma delta T cells recognise markers of cellular stress resulting from infection or tumorigenesis. Gamma delta T cells are also believed to have a role in recognition of lipid antigens. The T cells induced by high dose glucocorticoids, and which may be induced by the methods of the disclosure may express CD3 to a very high level (“CD3 -very-high”). The T cells may express both CD4 and CD8. [096] Natural Killer T Cells (NKTs) are a heterogeneous group of T cells that share properties of both T cells and natural killer (NK) cells. In contrast to conventional T cells, NKTs are functionally mature when they exit the thymus, primed for rapid cytokine production. NKTs can directly kill cancer cells and tumor microenvironment macrophages, rapidly produce and release immune activating cytokines such as IFNgamma and IL-4, and activate other immune cells such as dendritic cells (DCs), NK cells, and B and T lymphocytes.

[097] The authors have found a novel type of NKT cells, denoted AVM NKT, which homes remarkably well to diseased tissues such as tumors in tumor killing models used to show efficacy of checkpoint inhibitors. AVM_NKT are mobilized only after AVM0703 treatment, as opposed to other NK and NKT which circulate continuously, therefore AVM_NKT numbers are unlimited in practice. Normal NK and NKT cells have been shown to reduce Influenza A mediated inflammation and disease severity, and CD1 lb+ DC have been implicated in protection against Respiratory Syncytial Virus and Influenza A (H1N1). The NKT cells induced by high dose glucocorticoids, and which may be induced by the methods of the disclosure may express CD3 to a very high level (“CD3 -very-high”), and: may express CD4, CD8, CD45, CD49b, CD62L, NK1.1, Ly6G, Seal, and/or TCR gamma/delta; and/or, may not express: C-kit, B220, FoxP3, and / or TCR alpha/beta.

Determining cell marker expression levels

[098] Markers expressed by NKT cells, T cells or DCs induced by the methods of the disclosure can be determined by reference to the level of marker expression by a typical NKT cell, T cell or DC population (respectively), e.g. taken from the patient prior to treatment. Where the expression level is said to be “very high” this can denote 50%, 60%, 70%, 80%, 90% or 100% higher level expression of the marker compared to the respective typical cell population. Expression levels may be determined by flow cytometry.

Examples

[0105] The following examples demonstrate that high dose glucocorticoids are able to bind to a receptor (ICAM3) that is distinct from the published intracellular or transmembrane glucocorticoid receptors, and which is highly expressed on lymphocytes, monocytes and neutrophils, as well as on cancer cell types such as melanoma and osteosarcoma.

[0106] These examples also demonstrate that high dose glucocorticoids are able to exert a concentration dependent, direct killing effect on these cancer cell types - an effect that is likely mediated by binding of glucocorticoids to ICAM3 causing the ICAM3 -expressing cell becoming marked for attack by other lymphocytes such as NKT cells and CD8+ T cells. ICAM3 shedding may also occur following glucocorticoid binding, further stimulating an immune response against these cell types

[0107] High doses of glucocorticoids, and other ICAM3 modulating agents thus represent a promising therapy for use in the treatment of cancer and diseases mediated by immune cells such as lymphocytes.

[0108] Acute high dose dexamethasone may also be referred to herein as Dex, AugmenStem™, PlenaStem™ or AVM0703.

EXAMPLE 1 - Acute high dose dexamethasone binds to Intracellular Adhesion Molecule 3

[0109] The present authors have identified that high dose glucocorticoids bind a receptor that is distinct from the published intracellular or transmembrane glucocorticoid receptors. When investigating high concentrations of glucocorticoids as a pre-conditioning regime before stem cell therapy or cellular immunotherapies (see, for example, WO2018/183927), the present authors surprisingly observed a degree of cancer cell killing in lymphoma models when high concentrations of glucocorticoids were administered in the absence of cellular therapy. Initial analysis of protein / RNA expression levels of the receptor mediating this effect in various organs found that it is highly expressed on hematopoietic organs and skin (see Figure 1), as well as by lymphomas (see Figure 2) and paediatric cancers (see Figure 3).

[0110] Subsequent investigation of the expression profile of proteins expressed by lymphoma cells lines and the biological responses observed by the authors in naive and tumor bearing mice identified the receptor mediating the direct cancer killing effect of high dose glucocorticoids as ICAM3. The restricted expression profile of ICAM3 gives AVM0703 and other acute high dose glucocorticoid treatments a preferred safety profile over other chemotherapeutics.

EXAMPLE 2 - AVM0703 Receptor (ICAM3) is expressed by U2 OS osteosarcoma cells and mediates AVM0703 induced in vitro apoptosis of U2 OS cells in a concentration-dependent manner.

[0111] As shown in Figure 4, the AVM0703 Receptor (ICAM3) is expressed by U2 OS osteosarcoma cells. In vitro administration of acute high dose dexamethasone triggered apoptosis of these cells in a concentration dependent manner (Figure 5). Dexamethasone base doses that induced apoptosis include 50, 100, 175, and 250 mM.

[0112] Consistent with these results, acute high dose dexamethasone was found to prevent A20 B lymphoma and B16F10 melanoma growth in vivo.

EXAMPLE 3 - Absent ex vivo effect of high concentration dexamethasone on whole blood or splenocvtes

[0113] Ex vivo whole blood or isolated splenocytes had no response to AVM0703 or dexamethasone base at concentrations between 100 uM up to 500 uM, the equivalent concentrations attained at peak in vivo dosing around Human Equivalent Dose (HED) 6 mg/kg and higher. These data demonstrate that at the doses preferred for cancer and infectious disease treatments (HED 6 mg/kg up to 30 mg/kg) AVM0703 does not activate glucocorticoid receptors nor the ICAM3 receptor directly expressed on lymphocytes, monocytes or neutrophils. The profound in vivo activity that is observed in naive mice and in cancer models must therefore be mediated through the mobilized supercharged Natural Killer T cells, T cells and dendritic cells after AVM0703 HED 6 mg/kg and higher. [0114] The incubation conditions shown in Table 2 were investigated.

Table 2: Incubation conditions Results: Whole blood ( study 6)

[0115] Samples were treated in triplicate with either 500 mM dexamethasone base, 50 pM RU486 (a steroid receptor antagonist), or 1% DMSO as control. A non-significant increase in neutrophils induced by RU486 treatment. Other immune cells types; lymphocytes, monocytes, eosinophils, basophils; displayed no change in numbers with dexamethasone base or RU486 treatment. The data indicates that dexamethasone base alone in whole blood does not induce the lymphocyte-killing activity seen in in vivo experiments. RU486 alone also has no killing activity on lymphocytes and can be given in combination without impacting lymphocyte levels. Results: Splenocytes ( study 24)

[0116] Splenocytes were cultured for 16 hours prior to assay execution. Flow cytometry was performed at four hours after dexamethasone base addition, and the results are shown in Figure 6. After 4 hours, dexamethasone base appears to have direct killing activity at concentrations lower than 100 pM, but does not trigger cell death above 100 pM. [0117] The results of Study 6 and 24 suggest that the mechanism of action is different between low and high concentrations of dexamethasone base, where high doses have no activity on splenocytes. This is in contrast to previous in vivo data, where the weight of the spleen is sharply reduced by AVM0703 dosing. (See WO2018/183927 and W02020/072713; both incorporated by reference in their entirety, for discussion of these in vivo effects.) The discrepancy between ex vivo and in vivo indicates that a different mechanism of action is occurring in vivo compared to ex vivo.

Results: Venetoclax 1

[0118] No significant difference was found for any measured parameter of CBC when whole blood was incubated with Placebo, DMSO, AVM0703 at 500 mM alone, or combined with venetoclax at 3 pM. Particularly, there is no significant effect on white blood cells. Lymphocytes, monocytes, and neutrophils do not exhibit the lymphodepletion or ablation observed in vivo. Thus, these results indicate that cells in whole blood are not influenced by AVM0703 via GCR activation (venetoclax increases glucocorticoid sensitivity).

Results; ex vivo glucocorticoid comparison

[0119] To determine whether the absence of ex vivo effect on monocytes, lymphocytes, and neutrophils was due to the concentration of dexamethasone base of 100 uM to 500 uM, or whether the different excipients in AVM0703 could be contributing we compared ex vivo treatment followed by CBC analysis among AVM0703 compared with other commercially available Dexamethasone Phosphate. There were no noticeable differences between the different formulations, indicating that it is the concentrations of dexamethasone base that have an unexpected ex vivo effect; i.e. the surprising lack of ex vivo cell death.
