Description:
TECHNICAL FIELD
[0001] The present disclosure relates to engineered immune cells that have an enhanced safety profile and large therapeutic window.
SEQUENCE LISTING
[0002] The present application is being filed with a Sequence Listing in electronic format. The Sequence Listing is provided as a file entitled A2TH-005-01US-Sequence-Listing.txt, created on Sep. 20, 2021 and is 404 kilobytes in size. The information in electronic format of the Sequence Listing is incorporated by reference in its entirety.
BACKGROUND
[0003] Approximately 1.8 million people per year are diagnosed with a form of cancer in the United States. Similarly, it is estimated that 23.5 million Americans suffer from an autoimmune disease, almost all of which decrease life expectancy. Despite continual advances in treatment, education, and detection, there are over 600,000 deaths per year attributed to cancer in the U.S., while autoimmune diseases remain a leading cause of death among patients under the age 65.
[0004] Engineered immune cells have been touted as potentially effective treatments for a variety of severe conditions like cancer, viral infections, auto-immune ailments, and organ transplant rejection. These immune cells, whether chimeric antigen receptor (CAR)-engineered cells or T cell receptor (TCR)-engineered cells, often show efficacious results in vitro. However, in vivo, these results are rarely duplicated. Often, these treatments show a lack of efficacy in vivo and/or produce such severe side effects, that they cannot be used as therapeutics. Thus, despite decades of consistent research, only two CAR T cell therapies have received FDA approval--Kymriah.TM. for acute lymphoblastic leukemia and Yescarta.TM. for diffuse large B-cell lymphoma.
SUMMARY OF THE INVENTION
[0005] The present disclosure provides engineered immune cells that comprise two types of modular, engineered ligand binding receptors caused to be expressed on the surface of the cells. The first of these receptors is an activating receptor, which is designed to activate when bound to a cognate ligand on the surface of another cell, causing it to trigger an activating signal. The immune cells are engineered such that when the strength of the activating signal crosses a threshold, it causes a cytotoxic response by the immune cell, killing the cell expressing the cognate ligand. The second of these receptors is a blocking receptor, which when bound to a cognate blocking ligand on the surface of a non-target cell, is designed to activate and trigger a blocking signal. The blocking signal blocks the activating signal, which prevents the cytotoxic response against the non-target cell.
[0006] Generally, the activating receptors are designed to bind to cognate activating ligands that are expressed on both target cells, such as tumor cells, and non-target cells. The blocking ligands may be expressed only by non-target cells, or expressed at lower levels by target cells compared to non-target cells. In this way, when the engineered immune cells contact target cells, the activating receptors bind to the activating ligands, which leads to the cytotoxic response. In contrast, when the engineered immune cells contact non-target cells, the blocking receptors bind to the blocking ligands, blocking the cytotoxic response. This designed scheme provides the general means by which the engineered immune cells safely kill target cells, while limiting effects on non-target cells. However, the immune cells of the present disclosure have been engineered to provide several other advantageous features that expand their therapeutic window and efficacy, while limiting deleterious effects.
[0007] One of these advantageous features is that, when activated, the blocking receptors have been designed to reduce cell surface expression of the activating receptors. Thus, as the immune cells circulate to areas of a patient's body lacking target cells, the levels of activating receptors expressed on the surface of the cell are reduced. The receptors can be configured such that this reduction is reversible upon the activating receptors binding to their cognate ligands in the absence of the blocking ligands. This intentionally lowers the likelihood that a cytotoxic response will be triggered in the absence of an appropriate target, which enhances the safety profile of the immune cells.
[0008] Further, by engineering the immune cells to reduce the expression of activating receptors in the absence of an appropriate target cell, the immune cells are less likely to exhibit chronic activation and/or ligand-independent tonic signaling. As a result, the immune cells of the present disclosure are designed to limit immune cell exhaustion, differentiation, and activation-induced immune cell death, while concurrently exhibiting high generation and persistence.
[0009] A further advantage of the engineered immune cells of the present disclosure is that, when they contact target and/or non-target cells, the activating and blocking receptors are designed to diffuse into regions on the immune cell surface proximate to the target and/or non-target cells. The receptors form micro-clusters in these regions. In micro-clusters proximate to non-target cells, the blocking receptors bind to cognate ligands on the proximate non-target cells. The receptors can be configured such that cross-talk between the receptors causes a localized reduction in surface expression of the activating receptors, recruits more blocking receptors to the micro-cluster, and prevents breakup of the micro-cluster. This leads to a localized signal that blocks cytotoxic effects on the non-target cell.
[0010] In contrast, when the engineered immune cells contact target cells, activating receptors in micro-clusters proximate to the target cells are activated. This leads to a localized signal that, when it passes a threshold, triggers a cytotoxic response by the immune cell that kills the proximate target cells. The immune cells and receptors can be configured such that binding of the activating receptors to their cognate ligands may also locally reverse any reduced surface expression of the activating receptor. This ensures a sufficiently strong activating signal to trigger the cytotoxic response on the proximate target cell.
[0011] The immune cells of the present disclosure can form these aforementioned micro-clusters when simultaneously contacting both target and non-target cells. This ensures an appropriate, localized response that kills target cells, while minimizing deleterious effects on non-target cells.
[0012] The immune cells of the present disclosure also feature blocking receptors that are engineered to produce a ligand-dependent signal that dominates and blocks the activating signal from the activating receptors. This ensures that the immune cells can be configured to possess a strong safety profile with a wide therapeutic window.
[0013] Moreover, in some methods and systems of the disclosure, the engineered immune cells can be produced based on the levels of blocking and activating ligands expressed by non-target cells. Because the blocking receptors can be tuned to have a signal that dominates initial contact with a non-target cells, a sufficiently safe immune cell can be produced, without relying on a large surplus of blocking receptors expressed as compared to activating receptors. Further, the ability of the blocking receptors to reduce the surface expression of the activating receptors ensures that this level of safety increases in the presence of non-target cells.
[0014] Another advantage conferred by the immune cells of the present disclosure is that receptors can be produced using modular receptor components. Thus, the immune cells can be readily engineered to have receptor pairs that target desired ligands expressed on target and non-target cells. Moreover, the modular receptor components can be used and interchanged to tune or adjust the relative signal strengths of each receptor type. This ensures that an engineered immune cell's receptors provide a sufficiently strong activation signal, which can be adequately blocked to prevent non-target effects. A surprising discovery is that this modular nature extends to both chimeric antigen receptors (CAR) and T cell receptors (TCR). Not only are CARs and TCRs of the present disclosure able to interact with each other, but parts of CARs and TCRs can be interchanged to produce customized receptors and cells.
[0015] The relative signal strength and activity of each receptor type can also be modulated based on cross-talk between receptors. A surprising feature of the present disclosure is, not only that cross-talk can impact signal strength and activity, but that the impact of this cross-talk can change depending on the distance between pairs of blocking and activating receptors. As the distance between a blocking receptor and activating receptor decreases, the impact of this cross-talk increases. Thus, the present disclosure provides engineered immune cells configured to express receptors such that they are proximate to one another to ensure optimal interaction and strong cross-talk.
[0016] The receptors may be designed, for example, with physiochemical properties that ensure the receptors have a desired spacing. This spacing may ensure a maximum level of cross-talk between receptors and/or ensure that the receptors do not diffuse close enough to, for instance, invert the blocking receptor signal. The receptors can be engineered, for example, to have opposing charges or steric hindrances to prevent them from moving too close to one another. Alternatively, or in addition, the immune cells may be engineered to have receptors that are covalently linked to achieve a desired spacing. For example, a rigid covalent linker between the receptors can hold the receptors at a desired spacing from one another. The rigid linker concurrently keeps the receptors close enough to ensure cross-talk while maintain adequate spacing to prevent the blocking receptor from, for instance, inverting or becoming ligand-independent.
[0017] Another feature of the present disclosure is that the blocking receptor can be designed using interchangeable hinges that connect an extracellular ligand binding domain to a transmembrane domain and/or an intracellular domain. The hinges can be designed to have different lengths and flexibilities. The length and flexibility of a hinge can be used to tune the strength of the blocking signal. Longer and/or more flexible hinges can be used to increase the strength of the blocking receptor's signal or surface expression. In contrast, the blocking receptor can be engineered with shorter and/or more rigid hinges to decrease the strength of the blocking receptor's signal or surface expression. The blocking receptor can be configured to use a hinge selected from a group of hinges that have a known impact on the half maximal concentration (EC.sub.50) of the activating ligand for the activating receptor to cause the immune cell to trigger a cytotoxic response. This allows pairs of blocking and activating receptors to be chosen or engineered to exhibit a desired level of activation/inhibition.
[0018] Thus, the present disclosure provides engineered immune cells, and methods for reliably producing them, with a large therapeutic window, i.e., cells with a large range between their minimum effective dose and maximum tolerated dose. The cells possess target-sensitive receptors that produce an activation signal sufficient to trigger cytotoxic effects when encountering target cells, while concurrently producing minimal non-target effects. The engineered immune cells of the present disclosure also exhibit low exhaustion, differentiation, tonic signaling, and activation-induced immune cell death, and other features consistent with effective in vitro and in vivo function.
[0019] In one aspect, the present disclosure provides an engineered immune cell that includes an activating receptor expressed on a surface of the engineered immune cell. Binding of the activating receptor to an activating ligand on a target cell promotes a cytotoxic response by the engineered immune cell. The immune cell also includes a blocking receptor expressed on the surface of the engineered immune cell. Binding of the blocking receptor to a blocking ligand on a target cell causes the engineered immune cell to exhibit reduced surface expression of the activating receptor. High exogenous IL-2 may overcome this level of regulation, though the activation/blockade is still enforced by other features of intracellular signaling of the activator and blocker receptors.
[0020] Binding of the blocking receptor to the blocking ligand on the target cell may also cause the blocking receptor to trigger an inhibitory signal that blocks the activating signal, thereby preventing the cytotoxic response by the immune cell. The engineered immune may have an inhibitory signal dominates and blocks the activating signal.
[0021] The reduced surface expression of the activating receptor of the cells of the present disclosure may be reversible. The reduced surface expression of the activating receptor may reverse upon the engineered immune cell binding to the activating ligand on a target cell in the absence of the blocking ligand. The reduced surface expression of the activating receptor may be localized to a region of the engineered immune cell surface proximal to the blocking receptor. When a plurality of the blocking receptor binds to a plurality of the blocking ligand, the reduced surface expression may be localized to regions of the engineered immune cell surface proximal to blocking receptors.
[0022] When the immune cell encounters a target cell having both the blocking and activating ligands, a plurality of activating and blocking receptors diffuse into a region on the of the immune cell surface proximal to the target cell and form a micro-cluster. In the micro-cluster, binding of blocking receptors to the blocking ligands causes the engineered immune cell to exhibit reduced surface expression of the activating receptor in the micro-cluster.
[0023] In certain immune cells of the disclosure, the blocking receptor cannot bind to the blocking ligand until the activating receptor binds to the activating ligand.
[0024] The present disclosure also provides method for treating a cancer using the immune cells of the disclosure. In certain methods of the disclosure, the method includes providing an engineered immune cell to a patient, wherein the engineered immune cell comprises an activating receptor and a blocking receptor, each expressed on a surface of the engineered immune cell. In certain methods, when the engineered immune cell encounters a tumor cell of the patient, the activating receptor binds to an activating ligand on the tumor cell while the blocking receptor remains unbound. This promotes a cytotoxic response by the engineered immune cell that results in a cytotoxic effect on the tumor cell. When the engineered immune cell encounters a normal cell of the patient, the blocking receptor binds to a blocking ligand on the normal cell and causes the engineered immune cell to exhibit reduced surface expression of the activating receptor. This causes a signal from the blocking receptor to dominate a signal from the activating receptor, which prevents the cytotoxic response by the engineered immune cell.
[0025] In certain methods, the reduced surface expression of the activating receptor is temporary. The reduced surface expression may be reversible. The reduced surface expression may be reversed upon the engineered immune cell binding to the first ligand on a tumor cell.
[0026] In certain methods of the disclosure, the reduced surface expression of the activating receptor may be localized to a region of the engineered immune cell surface proximal to the blocking receptor bound to the blocking ligand on the normal cell. A plurality of the blocking receptor may bind to a plurality of the blocking ligand on the normal cell, and the reduced surface expression may be localized to the region of the engineered immune cell surface proximal to the plurality of the blocking receptor.
[0027] A further aspect of the disclosure are methods of producing an engineered immune cell with activating and blocking receptors. The methods of the disclosure may include, producing an engineered immune cell that expresses activating receptors and blocking receptors based on a ratio of a quantity of an activating ligand to a quantity of a blocking ligand that are expressed in non-tumor cells of a patient.
[0028] In certain methods, a tumor cell of a patient expresses the activating ligand and does not express the blocking ligand.
[0029] In certain methods of the disclosure, binding of the activating receptors to the activating ligands triggers an activating signal that promotes a cytotoxic response by the engineered immune cell. Additionally, binding of the blocking receptors to blocking ligands on a non-tumor cell may cause the blocking receptors to trigger an inhibitory signal that blocks the activating signal.
[0030] In certain methods of the disclosure, the engineered immune cell expresses the blocking and activating receptors at a ratio based on the ratio of the quantity of the activating ligand to the quantity of the blocking ligand that are expressed in the non-tumor cells of the patient.
[0031] In some methods, the inhibitory signal of one of the blocking receptors dominates and blocks the activating signal of one of the activating receptors.
[0032] In certain methods, the ratio of the blocking receptors to the activating receptors is less than 1. The ratio of the blocking receptors to the activating receptors, needed to achieve a blocking signal to provide a certain level of blocking for the activating signal, may be inversely proportional to the quantity of the activating ligand expressed on non-tumor cells of the patient. In certain methods, when the immune cell contacts a non-tumor cell of the patient the blocking receptors bind to blocking ligands on the non-tumor cell and reversibly increase the ratio of blocking receptors to activating receptors expressed by the immune cell.
[0033] In certain methods of the disclosure, each blocking receptor comprises a ligand binding domain (LBD), a hinge, transmembrane domain, and intracellular domain (ICD), and the LBD, hinge, and ICD have a known effect on the strength of the inhibitory signal. Each activating receptor may comprise a ligand binding domain (LBD), a hinge, transmembrane domain, and the LBD has a known effect on the activation signal.
[0034] The present disclosure also provides a method of producing an engineered immune cell that includes obtaining a sample from a patient comprising target and non-target cells; performing an assay to determine a ratio of a quantity of an activating ligand to a quantity of a blocking ligand expressed on the non-target cells; and producing an engineered immune cell that expresses activating receptors and blocking receptors based on the determined ratio.
[0035] In certain methods, the target cells express the activating ligand and do not express the blocking ligand.
[0036] In some methods, binding of the activating receptors to the activating ligands triggers an activating signal that promotes a cytotoxic response by the engineered immune cell; and
[0037] binding of the blocking receptors to blocking ligands on a non-target cell causes the blocking receptors to trigger an inhibitory signal that blocks the activating signal.
[0038] In some methods, the engineered immune cell expresses the blocking and activating receptors at a ratio based on the ratio of the quantity of the activating ligand to the quantity of the blocking ligand that are expressed in the non-target cells of the patient.
[0039] In certain methods, the inhibitory signal of one of the blocking receptors dominates and blocks the activating signal of one of the activating receptors. The ratio of the blocking receptors to the activating receptors is less than 1 in certain methods. The ratio of the blocking receptors to the activating receptors may be inversely proportional to the quantity of the activating ligand expressed on non-target cells of the patient. In some methods, when the immune cell contacts a non-target cell of the patient the blocking receptors bind to blocking ligands on the non-target cell and reversibly increases the ratio of blocking receptors to activating receptors expressed by the immune cell.
[0040] In certain methods of the disclosure, each blocking receptor comprises a ligand binding domain (LBD), a hinge, transmembrane domain, and intracellular domain (ICD), and the LBD, hinge, and ICD have a known effect on the strength of the inhibitory signal. Each activating receptor may comprise a ligand binding domain (LBD), a hinge, transmembrane domain, and the LBD has a known effect on the activation signal.
[0041] In a further aspect, the present disclosure provides engineered immune cells with activating and blocking receptors that exhibit cross-talk between receptors. Thus, the present disclosure provides an engineered immune cell with an activating receptor that triggers a cytotoxic signal that promotes a cytotoxic response of the engineered immune cell when the activating receptor binds a first ligand of a target cell; a blocking receptor that sends an interfering signal that inhibits the cytotoxic response of the engineered immune cell when the blocking receptor binds a second ligand of the target cell, wherein cross-talk between the activating receptor and the blocking receptor affects an activation threshold for the cytotoxic response.
[0042] In certain immune cells, in the absence of the first and second ligands, the effect of the cross-talk on the activation threshold is minimized and/or reduced. The effect of the cross-talk on the activation threshold may increase with proximity of the activating receptor to the blocking receptor.
[0043] In certain immune cells of the disclosure, the activating receptor and blocking receptor are covalently linked together, or have physicochemical properties favoring interaction with one another such that the receptors are proximal to one another.
[0044] In some immune cells of the disclosure, when the blocking receptor binds to the second ligand, the cross-talk between the blocking and activating receptors causes the immune cell to exhibit reduced surface expression of the activating receptor.
[0045] An immune cell of the disclosure may include a plurality of the activating and blocking receptors, and when the immune cell contacts a target cell the plurality of the activating and blocking receptors diffuses into a region on the surface of the immune cell proximal to the target cell and forms a micro-cluster in which the effect of the cross-talk on the activation threshold is localized.
[0046] In some immune cells of the disclosure, cross-talk between the activating receptor and the blocking receptor prevents the blocking receptor from binding to the second ligand until the activating receptor binds to the first ligand.
[0047] The present disclosure also provides methods for treating cancer using the immune cells of the present disclosure. Certain methods may include providing an engineered immune cell to a patient, wherein the engineered immune cell comprises an activating receptor and a blocking receptor, each expressed on a surface of the engineered immune cell. The activating receptor may trigger a cytotoxic signal that promotes a cytotoxic response of the engineered immune cell when the activating receptor binds a first ligand of a target cell; and the blocking receptor may send an interfering signal that inhibits the cytotoxic response of the engineered immune cell when the blocking receptor binds a second ligand of the target cell, wherein cross-talk between the activating receptor and the blocking receptor affects an activation threshold for the cytotoxic response.
[0048] In certain methods, the absence of the second ligand, the effect of the cross-talk on the activation threshold is minimized and/or reduced. The effect of the cross-talk on the activation threshold may increase with proximity of the activating receptor to the blocking receptor.
[0049] In certain methods, the activating receptor and blocking receptor are linked together or have physicochemical properties favoring interaction with one another, such that the receptors are proximal to one another.
[0050] In certain methods, when the blocking receptor binds to the second ligand, the cross-talk between the blocking and activating receptors causes the immune cell to exhibit reduced surface expression of the activating receptor. The immune cell may include a plurality of the activating and blocking receptors, and when the immune cell contacts a target cell the plurality of the activating and blocking receptors diffuses into a region on the surface of the immune cell proximal to the target cell and forms a micro-cluster in which the effect of the cross-talk on the activation threshold is localized.
[0051] In methods of the disclosure, the cross-talk between the activating receptor and the blocking receptor may prevent the blocking receptor from binding to the second ligand until the activating receptor binds to the first ligand.
[0052] The present disclosure also provides methods of producing engineered immune cells as disclosed herein. Certain methods include, determining an amount of cross-talk between an activating receptor and a blocking receptor for an engineered immune cell, wherein the amount of cross-talk between the activating receptor and the blocking receptor affects an activation threshold for the cytotoxic response; and producing an engineered immune cell that expresses different concentrations of activating receptors and blocking receptors based on the determined amount of cross-talk between the activating receptor and the blocking receptor.
[0053] In some methods for producing immune cells, in the absence of cognate ligands for the activating and blocking receptors, the amount of the cross-talk is minimized and/or reduced. The methods may include producing an engineered immune cell that expresses different concentrations of activating receptors and blocking receptors is further based on a ratio of a quantity of an activating ligand to a quantity of a blocking ligand that are expressed in non-tumor cells of a sample.
[0054] The cross-talk between the activating receptor and the blocking receptor may prevent the blocking receptor from binding to the blocking ligand until the activating receptor binds to the activating ligand. In certain methods, an amount of the cross-talk between the activating receptor and blocking receptor increases with proximity of the activating receptor to the blocking receptor.
[0055] Methods include producing immune cells where the activating receptor and blocking receptor may be covalently linked, or have physicochemical properties favoring interaction with one another such that the receptors are proximal to one another.
[0056] In a further aspect, the present disclosure provides engineered immune cells with activating and blocking receptors in which the blocking receptor provides an inhibitory signal that dominates the activation signal from the activating receptor.
[0057] Thus, the present disclosure includes an engineered immune cell with an activating receptor on the surface of the engineered immune cell, wherein binding of the activating receptor to a first ligand on a target cell causes the activating receptor to trigger an activating signal that promotes a cytotoxic response by the engineered immune cell; and a blocking receptor on the surface of the immune cell, wherein binding of the blocking receptor to a second ligand on a target cell causes the blocking receptor to trigger an inhibitory signal stronger than the activating signal such that the inhibitory signal dominates and blocks the activating signal from the activating receptor, thereby preventing a localized cytotoxic response by the engineered immune cell.
[0058] In certain immune cells of the disclosure, binding of the blocking receptor to the second ligand may cause the engineered immune cell to exhibit reduced surface expression of the activating receptor. The reduced surface expression may be reversible.
[0059] The immune cells may include a plurality of activating and blocking receptors and the ratio of the blocking receptors to the activating receptors expressed by the immune cells is less than or equal to 1.
[0060] In certain immune cells of the disclosure, the blocking receptor does not bind to the second ligand until the activating receptor binds to the activating ligand.
[0061] In certain cells, the inhibitory signal may be localized to a region of the engineered immune cell surface adjacent to the blocking receptor. Similarly, the activation signal may be localized to a region of the engineered immune cell surface adjacent to the activating receptor.
[0062] When the immune cells of the disclosure encounter a target cell having both the first and second ligands, a plurality of activating and blocking receptors may diffuse into a region on the of the immune cell surface proximal to the target cell and form a micro-cluster in which the blocking receptors prevent the localized cytotoxic response by the engineered immune cells. Binding of the blocking receptors in the micro-cluster to the second target antigen may prevent breakup of the micro-cluster. When the immune cells simultaneously contact a second target cell having the first ligand and lacking the second ligand, a second plurality of the activating receptors may diffuse into a second region on the surface of the immune cells proximal to the second target cell and form a second micro-cluster that promotes the localized cytotoxic response by the engineered immune cells that results in a cytotoxic effect on the second target cell.
[0063] The present disclosure also provides methods for treating cancer using the immune cells of the present disclosure. The methods include a method in which an engineered immune cell is provided to a patient, wherein the engineered immune cell comprises an activating receptor and a blocking receptor, each expressed on a surface of the engineered immune cell, wherein: when the engineered immune cell encounters a tumor cell, the activating receptor binds to a first ligand on the tumor cell and the activating receptor triggers an activating signal in the engineered immune cell that promotes a cytotoxic response by the engineered immune cell that results in a cytotoxic effect on the tumor cell; and when the engineered immune cell encounters a normal cell, the activating receptor binds to the first ligand on the normal cell and the blocking receptor binds to a second ligand on the normal cell, wherein the activating receptor triggers an activating signal in the engineered immune cell and the blocking receptor triggers an inhibitory signal in the engineered immune cell that is stronger than the activating signal such that the inhibitory signal dominates and blocks the activating signal from the activating receptor, thereby preventing a localized cytotoxic response by the engineered immune cell.
[0064] In some methods, binding of the blocking receptor to the second ligand causes the engineered immune cell to exhibit reduced surface expression of the activating receptor. The reduced surface expression may be reversible.
[0065] In methods of the disclosure, the immune cell may express different concentrations of the activating and blocking receptors based on a ratio of a quantity of the first ligand to a quantity of a second ligand expressed in a normal cell of the patient. The ratio of the concentration of blocking receptors expressed to activating receptors expressed may be less than or equal to 1.
[0066] In certain methods, when the immune cell encounters at least one tumor cell, a first plurality of the activating receptors diffuses into a first region on the surface of the immune cell proximal to the tumor cell and forms a first micro-cluster that promotes the localized cytotoxic response by the immune cell that results in a cytotoxic effect on the tumor cell. When the immune cell simultaneously encounters a normal cell, a plurality of the activating and blocking receptors may diffuse into a second region on the surface of the immune cell proximal to the normal cell and form a second micro-cluster causing the inhibitory signal from the blocking receptors to dominate the activating signal from the activating receptors in the second micro-cluster preventing the localized cytotoxic response by the engineered immune cell on the normal cell. Binding of the blocking receptors in the second micro-cluster to the second ligand may prevent breakup of the second micro-cluster.
[0067] In some methods of the disclosure, the blocking receptor does not bind to the second ligand until the activating receptor binds to the activating ligand.
[0068] Some methods include cross-talk between the activating receptor and the blocking receptor that affects an activation threshold for the localize cytotoxic response.
[0069] In a further aspect, the present disclosure provides engineered immune cells with activating and blocking receptors that have multiplex and localized activity. An immune cell of the disclosure may include activating and blocking receptors on a surface of the cell. When the engineered immune cell encounters a tumor cell and a healthy cell a first region of the activating and blocking receptors forms proximal to the healthy cell and blocking receptors in the first region inhibit cytotoxic effects on the healthy cell, while, simultaneously, a second region of the activating and blocking receptors forms proximal to the tumor cell and promotes a cytotoxic response by the engineered immune cell that exhibits cytotoxic effects on the tumor cell.
[0070] The activating and blocking receptors in the first region may bind to cognate activating and blocking ligands on the healthy cell, and the activating receptors in the second region may bind to cognate activating ligands on the tumor cell. The activating and blocking receptors may form a first micro-cluster in the first region, and the activating and blocking receptors may form a second micro-cluster in the second region.
[0071] Binding of the blocking receptors in the first micro-cluster to the cognate blocking ligands on the healthy cell may cause the engineered immune cell to exhibit reduced surface expression of the activating receptor in the first micro-cluster. Binding of the blocking receptors in the first micro-cluster to the cognate blocking ligands on the healthy cell may prevent breakup of the first micro-cluster.
[0072] The immune cell may express different concentrations of the activating and blocking receptors based on a ratio of a quantity of the activating ligand to a quantity of the blocking ligand expressed in a healthy cell. The ratio of the concentration of blocking receptors to activating receptors expressed by the immune cell may be less than or equal to 1.
[0073] In certain immune cells of the disclosure, the blocking receptors do not bind to the cognate blocking ligands until the activating receptors bind to cognate activating ligands.
[0074] In some immune cells of the disclosure, the cytotoxic response by the engineered immune cell that exhibits cytotoxic effects on the tumor cell is localized to the second region. The localized cytotoxic response does not exhibit cytotoxic effects on the healthy cell.
[0075] The present disclosure also provides methods for treating cancer using the immune cells of the disclosure. A method for treating cancer may include providing an engineered immune cell to a patient, the engineered immune cell comprising activating and blocking cell-surface receptors. When the engineered immune cell encounters a tumor cell and a healthy cell of the patient, a first set of the activating and blocking receptors collect into a first cell-surface region of the engineered immune cell proximal to the healthy cell in which the blocking receptors inhibit cytotoxic effects of the engineered immune cell on the healthy cell. Simultaneously, a second set of the activating and blocking receptors collect into a second cell-surface region of the engineered immune cell proximal to the tumor cell in which the activating receptors promote a cytotoxic response by the engineered immune cell that kills the tumor cell.
[0076] The activating and blocking receptors in the first cell-surface region may bind to cognate activating and blocking ligands on the healthy cell, and the activating receptors in the second cell-surface region may bind to cognate activating ligands on the tumor cell.
[0077] The activating and blocking receptors may form a first micro-cluster on the first cell-surface region, and the activating and blocking receptors may form a second micro-cluster on the second cell-surface region.
[0078] Binding of the blocking receptors in the first micro-cluster to the cognate blocking ligands on the healthy cell may cause the engineered immune cell to exhibit reduced surface expression of the activating receptor in the first micro-cluster. Binding of the blocking receptors in the first micro-cluster to the cognate blocking ligands on the healthy cell may prevent breakup of the first micro-cluster.
[0079] In some methods of the disclosure, the immune cell expresses different concentrations of the activating and blocking receptors based on a ratio of a quantity of the activating ligand to a quantity of a blocking ligand expressed in a healthy cell. The ratio of the concentration of blocking receptors to activating receptors expressed by the immune cell may be less than or equal to 1.
[0080] In certain methods, blocking receptors do not bind to the cognate blocking ligands until the activating receptors bind to the cognate activating ligands.
[0081] In certain methods of the disclosure, the cytotoxic response is localized to the second cell-surface region. The localized cytotoxic response does not exhibit cytotoxic effects on the healthy cell.
[0082] In a further aspect, the present disclosure provides immune cells that have activating and blocking receptors that form micro-clusters on the surface of the immune cells.
[0083] An engineered immune cell of the disclosure may include activating and blocking receptors on a surface of the engineered immune cell, wherein: when the engineered immune cell encounters a tumor cell, a first plurality of the activating receptors diffuse into a first region on the surface of the engineered immune cell and form a first micro-cluster proximal to the tumor cell that promotes a cytotoxic response by the engineered immune cell that results in cytotoxic effects on the tumor cell; and when the engineered immune cell encounters a normal cell, a second plurality of the activating and blocking receptors diffuse into a second region on the surface of the engineered immune cell and form a second micro-cluster proximal to the normal cell, wherein the blocking receptors in the second micro-cluster inhibit cytotoxic effects on the normal cell.
[0084] The activating receptors in the first micro-cluster may bind to cognate activating ligands on the tumor cell, and the activating and blocking receptors in the second micro-cluster may bind to cognate activating and blocking ligands on the normal cell. When the immune cell encounters a normal cell, the second micro-cluster may mediate formation of a complementary cluster of ligands on the normal cell. Binding of the blocking receptors in the second micro-cluster to the cognate blocking ligands on the normal cell may cause the engineered immune cell to exhibit reduced surface expression of the activating receptor in the second micro-cluster. Binding of the blocking receptors in the second micro-cluster to the cognate blocking ligands on the normal cell may prevent breakup of the second micro-cluster.
[0085] In some immune cells of the disclosure, when the immune cell simultaneously contacts a normal cell and a tumor cell, the first plurality of the activating receptors diffuse into the first region and form the first micro-cluster proximal to the tumor cell that promotes the cytotoxic response by the engineered immune cell that results in cytotoxic effects on the tumor cell; and the second plurality of the activating and blocking receptors diffuse into the second region and form the second micro-cluster proximal to the normal cell in which the blocking receptors inhibit cytotoxic effects on the normal cell. Expression of the activating receptor in the second micro-cluster may be reduced after the second micro-cluster forms.
[0086] The immune cell may express different concentrations of the activating and blocking receptors based on a ratio of a quantity of the activating ligand to a quantity of a blocking ligand expressed in a normal cell of a patient. The ratio of the concentration of blocking receptors expressed to activating receptors expressed is less than or equal to 1.
[0087] In some immune cells of the disclosure, the blocking receptors do not bind to the cognate blocking ligands until the activating receptors bind to the cognate activating ligands.
[0088] The present disclosure provides methods for treating cancer using the immune cells disclosed herein. A method for treating cancer may include providing an engineered immune cell to a patient, the engineered immune cell comprising activating and blocking cell-surface receptors.
[0089] When the engineered immune cell encounters a normal cell, a first plurality of the activating and blocking receptors collect into a micro-cluster within a region of the cell-surface of the engineered immune cell proximal to the normal cell, wherein binding of one of the blocking receptors in the micro-cluster to a blocking ligand on the normal cell inhibits breakup of the micro-cluster, and wherein the engineered immune cell kills tumor cells that exhibit an activating ligand bound by the activating receptor and do not exhibit the blocking ligand such that the blocking receptor remains unbound.
[0090] When the immune cell simultaneously contacts a normal cell and a tumor cell, a first plurality of the activating receptors may diffuse into the first region and form the first micro-cluster proximal to the tumor cell that promotes the cytotoxic response by the engineered immune cell that results in cytotoxic effects on the tumor cell, and a second plurality of the activating and blocking receptors may diffuse into the second region and form the second micro-cluster proximal to the normal cell, wherein binding of one of the blocking receptors in the second micro-cluster to a first ligand on the normal cell inhibits breakup of the micro-cluster.
[0091] Binding of the blocking receptors in the second micro-cluster to the first ligands on the normal cell inhibits the cytotoxic effects on the normal cell. The cytotoxic effects on the tumor cell may be localized proximal to the first micro-cluster.
[0092] Binding of the blocking receptor to the first ligand on the normal cell may cause a plurality of the first ligand on the normal cell to diffuse into a region proximal to the immune cell and form a complementary micro-cluster. Binding of the blocking receptors in the micro-cluster to the first ligand on the normal cell may cause the engineered immune cell to exhibit reduced surface expression of the activating receptor in the micro-cluster. The reduced surface expression may be reversible.
[0093] The immune cell may express different concentrations of the activating and blocking receptors based on a ratio of a quantity of the first ligand to a quantity of the second ligand expressed on a normal cell. The ratio of the concentration of blocking receptors to activating receptors expressed by the immune cell may be less than or equal to 1.
[0094] In certain methods of the disclosure, the blocking receptors in the micro-cluster do not bind to the first ligands until the activating receptors bind to the second ligands on the normal cell.
[0095] In a further aspect, the present disclosure provides engineered immune cells and methods of making and using them wherein the immune cells comprise a hinge that modulates an effect of the blocking signal and/or receptors.
[0096] Thus, the present disclosure provides a method of producing an engineered immune cell, the method including, causing an immune cell to express cell surface activating receptors and blocking receptors, wherein the blocking receptors comprise a selected hinge. Binding of the activating receptors to activating ligands on a target cell triggers an activating signal that promotes a cytotoxic response by the immune cell. Binding of the blocking receptors to blocking ligands on a non-target cell causes the blocking receptors to trigger a blocking signal that inhibits the activating signal. The selected hinge is selected to modulate an effect of the blocking signal on the activating signal.
[0097] In certain methods, the selected hinge comprises a peptide having a certain length, and the length of the peptide modulates the effect of the blocking signal on the activating signal. The effect of the blocking signal on the activating signal may be an increased inhibition of the activating signal. The increased inhibition of the activating signal may increase a half maximal effective concentration (EC.sub.50) of the activating ligand for the activating receptors to promote the cytotoxic response.
[0098] In certain methods and immune cells of the disclosure, cross-talk and/or structure function interactions between the hinge of the blocking receptor and the activating receptor further impart different signal strengths for the blocking receptor.
[0099] The effect of the blocking signal on the activating signal may be a decreased inhibition of the activating signal, and the length of the peptide is less than about 24 amino acids.
[0100] In certain aspects of the disclosure, the engineered immune cell is caused to express the blocking and activating receptors at a ratio, and the ratio blocking receptors to activating receptors expressed is decreased as the length of the peptide of the selected hinge is increased. The peptide may further have a degree of flexibility, and the peptide's length and degree of flexibility modulate the effect of the blocking signal on the activating signal.
[0101] The selected hinge may be selected from hinges that each have a known effect on the EC.sub.50 of the activating ligand for the activating receptors to promote the cytotoxic response. The length of the peptide of each hinge that may have a known effect on the EC.sub.50 of the activating ligand is between 10 and 64 amino acids in length. The peptide of the selected hinge may be at least 24 amino acids in length. The peptide of the selected hinge may be at least 64 amino acids in length. In certain aspects, the hinge having a peptide of 64 amino acids in length causes at least a fifty-fold increase in the EC.sub.50 relative to a hinge having a peptide of 10 amino acid in length. In certain aspects, the hinges that each have a known effect on the EC50 comprise hinges 2B1, 2B1 truncated, PD-1, CTLA4, BTLA, SEQ ID NO: 392, SEQ ID NO: 393, SEQ ID NO: 394, SEQ ID NO: 395, SEQ ID NO: 396 and SEQ ID NO: 397.
[0102] In certain aspects of the disclosure, the length of the peptide increases surface expression of the blocking receptor.
[0103] In certain aspects, the hinge peptide is derived from leukocyte immunoglobulin-like receptor subfamily B member 1 (LILRB1).
[0104] In certain aspects of the disclosure, the hinge comprises a peptide having a degree of flexibility, and the peptide's degree of flexibility modulates the effect of the blocking signal on the activating signal. The peptide may be a flexible peptide and the effect of the blocking signal on the activating signal is an increased inhibition of the activating signal. The flexible peptide may comprise glycine-glutamine repeats and/or glycine-serine repeats.
[0105] In certain aspects, the hinge comprises a rigid peptide, and the peptide and the effect of the blocking signal on the activating signal is reduced inhibition of the activating signal. The rigid peptide may include, for example, an alpha-helix, repeats of (XP) where X is any amino acid, and/or repeats consisting of alanine, glutamic acid, and lysine.
[0106] In certain aspects, the present disclosure provides engineered immune cells, and methods of making and using the same, wherein activating and blocking receptors are spaced apart by at least an average minimum distance on the immune cell surface.
[0107] Thus, in certain aspects, the disclosure provides a method of producing an engineered immune cell, the method including, causing an immune cell to express cell surface activating and blocking receptors. Binding of the activating receptor to an activating ligand on a target cell triggers an activating signal that promotes a cytotoxic response by the engineered immune cell. Binding of the blocking receptor to a blocking ligand on a non-target cell causes the blocking receptor to trigger a blocking signal that inhibits the activating signal. Wherein the receptors remain spaced apart by at least an average minimum distance on the immune cell surface.

DETAILED DESCRIPTION
[0153] The present disclosure provides engineered immune cells featuring "AND NOT" Boolean logic by expressing engineered activating and blocking receptors. The cells are designed such that when the activating receptors bind to cognate activating ligands on a target cell, they produce an activating signal. If the strength of the activating signal crosses a threshold, it causes a cytotoxic response by the immune cell, killing the cell expressing the cognate ligands. The second of these receptors is a blocking receptor, which is designed to bind to a cognate blocking ligand on the surface of another cell, thereby activating the receptor and causing it to trigger a blocking signal that blocks the activating signal, which prevents the cytotoxic response. The "AND NOT" Boolean logic engineered into the immune cells of the present disclosure makes them ideal for use as therapeutic agents.
[0154] Thus, in an exemplary method of the disclosure, a patient diagnosed with a medical condition, such as cancer, is treated with engineered immune cells that target and kill the patient's cancer cells while preserving their normal, healthy cells. One or more cellular samples may be taken from the patient, such as from a blood draw or tumor biopsy. Target cells, such as tumor cells, are identified in the sample. The identified target cells are assayed to determine the levels of expression of one or more cell-surface ligands. This may include, for example, assessing RNA expression profiles for various cell-surface receptors or using antibody probes that bind to certain cell surface receptors. Assaying target cells may determine, for example, that target cells do not express a certain cell surface ligand due to a loss of heterozygosity.
[0155] Then, immune cells, such as T cells, are harvested from the patient. These cells are caused to express engineered activating and blocking receptors. The blocking receptor is designed to bind to a blocking ligand expressed on healthy cells of the patient. This blocking ligand may be chosen because it is lost from cancer cells, e.g., due to loss of heterozygosity. The activating receptor is designed to bind to an activating ligand that is expressed on both healthy cells and cancer cells of the patient.
[0156] After the engineered immune cells are proliferated, the cells are administered to the patient. The immune cells are designed such that when an immune cell encounters a cancer cell in the patient's body, the activating receptors bind to activating ligands on the cancer cell. This triggers a cytotoxic immune response by the immune cell that kills the cancer cell. When the immune cell encounters a healthy cell the activating and blocking receptors bind to activating and blocking ligands on the healthy cell. Binding of the blocking receptors to blocking ligands inhibits and blocks the cytotoxic immune response triggered by the activating receptors binding to activating ligands. In this way, the engineered immune cells are designed to limit deleterious effects on non-target cells.
[0157] FIG. 1 shows a schematic of this "AND NOT" Boolean logic in the immune cells of the present disclosure. In FIG. 1, the immune cells 103 comprise a blocking receptor 105 and an activating receptor 107. A non-target cell 109 expresses an activating ligand 111 and blocking ligand 113. When the immune cell 103 contacts the non-target cell, the activating receptor 107 binds to the activating ligand 111 triggering an activating signal 117. Concurrently, the blocking receptor 105 binds to the blocking ligand 113, triggering a blocking signal 115. As shown schematically, when the immune cell 103 contacts a non-target cell, the strength of blocking signal is greater than the activating signal 119. Binding both blocking ligands and activating ligands causes the "AND NOT" state in the immune cell. The signal from the blocking receptors blocks the activating signal. As such, the activating signal cannot pass the threshold to trigger a cytotoxic response, which prevents a deleterious effect on the non-target cell expressing both ligands.
[0158] Conversely, a target cell 121, such as a tumor cell, expresses a blocking ligand 111, but does not express an activating ligand, or expresses an activating ligand at a lower level compared to the non-target cell 109. Thus, when the immune cell 103 contacts the target cell 121, the activating receptor 107 binds to the activating ligand 111, triggering an activating signal 117. As shown schematically, when the immune cell 103 contacts a non-target cell, the strength of the activating signal is greater than the blocking signal 123. When the strength of the activating signal crosses an activation threshold, the immune cell produces a cytotoxic response 125 that kills the target cell 121.
[0159] Generally, the cognate antigens chosen for the activating receptors are expressed on both target cells, such as tumor cells, and non-target cells. The selected blocking ligands are expressed only by non-target cells, or expressed at lower levels by target cells compared to non-target cells. In this way, when the engineered immune cells contact target cells, the activating receptors bind to the activating ligands, which leads to the cytotoxic response. In contrast, when the engineered immune cells contact non-target cells, the blocking and activating receptors bind to their cognate blocking and activating ligands. This completes the "AND NOT" Boolean logic, thereby blocking the cytotoxic response. This scheme provides the general means by which the engineered immune cells safely kill target cells while limiting effects on non-target cells.
[0160] Engineered immune cells have been used as cancer therapies, such as immunotherapies. Traditionally, engineered immune cells have been designed to target molecular targets such as neo-antigens. Neo-antigens are a class of somatic mutant proteins that are mutated during somatic growth of tumors. They provide ideal targets for immune cell therapies because they comprise variants not found on non-target, healthy cells of a patient. However, very few cancers express neo-antigens. Thus, different targets must be pursued to treat most types of cancer using engineered immune cells. However, in prior immune cell therapies that lacked the blocking receptors of the present disclosure, when the immune cells targeted antigens expressed by healthy and non-health cells, severe adverse effects arose due to non-target activity. In cancer immunology, this phenomenon is known as on-target, off-tumor recognition.
[0161] The engineered immune cells and receptors of the present disclosure provide greater flexibility in choice of molecular target. The efficacy of the blocking receptor ensures that non-target effects are limited. Thus, the immune cells of the present disclosure can be designed to target widely expressed, cell surface molecules as the activating ligand. Exemplary ligands include a cell adhesion molecule, a cell-cell signaling molecule, an extracellular domain, a molecule involved in chemotaxis, a glycoprotein, a G protein-coupled receptor, a transmembrane, a receptor for a neurotransmitter or a voltage gated ion channel.
[0162] Activating receptors of the present disclosure may be configured to target activating ligands that are encoded by genes with essential cellular functions. Advantageously, this can prevent antigen escape, increasing the long-term efficacy of the engineered immune cells as a therapeutic. By selecting activating ligands encoded by genes with essential cellular functions, loss or escape of the ligand, such as through aneuploidy in cancer cells, is less likely. Thus, the activating ligand may be encoded by a gene that is haploinsufficient, i.e., loss of copies of the gene encoding the ligand are not tolerated by the cell and lead to cell death, or a disadvantageous mutant phenotype. In fact, the engineered immune cells of the present disclosure may be designed to target activating ligands expressed on all cells of patient.
[0163] Advantageously, because the immune cells of the present disclosure can be engineered to use widely-expressed activating ligands, several problems can be avoided. For example, prior engineered immune cells often targeted minimally expressed antigens, such as certain neo-antigens. Thus, to ensure an adequate activating signal, prior immune cells were engineered with activating receptors that had very high expression or affinities for their activating ligands.
[0164] However, merely increasing the density or affinity of receptors is inadequate to ensure efficacy. High receptor affinity can lead to proportionally severe, toxic effects on non-target cells. It can also hinder an engineered immune cell from disassociating from a target cell, which limits the ability of the immune cell to subsequently bind to and kill other target cells. Further, high affinity can cause receptors to be continually activated. This chronic activation can lead to immune cell exhaustion, reduced generation and persistence, increasing differentiation to undesired phenotypes, and activation-induced immune cell death. Increasing density can lead to similar effects through ligand-independent, tonic signaling.
[0165] Use of widely expressed activating ligands, made safe through the use of a blocking receptor, allows the engineered immune cells of the present disclosure to avoid these potential issues.
[0166] The blocking receptor can be designed to bind to a cell surface molecule not expressed on the surface of the target cell, or expressed at sufficiently low levels on a target cell. Thus, where the engineered immune cells are used to treat cancer, the blocking ligand may be chosen based on the loss of heterozygosity (LOH) of the target cancer cells, i.e., the cancer cells no longer express the ligand due to a loss of genetic material from one of the homologous chromosomes. Exemplary genes whose expression is frequently lost in cancer cells, for example due to LOH, include, HLA class I alleles, minor histocompatibility antigens (MiHAs), and Y chromosome genes (in males where the homologous chromosome is the X chromosome).
[0167] As will be discussed, the immune cells of the present disclosure possess several features that leverage the general nature of the "AND NOT" Boolean logic, to provide effective, target-specific effects while minimizing deleterious non-target effects.
[0168] Reduced Activator Expression
[0169] Surprisingly, the engineered immune cells of the present disclosure, which express activating and blocking receptors, can be designed to exhibit reduced surface expression of activating receptors when they contact non-target cells.
[0170] This ability to reduce surface expression is shown schematically in FIG. 2. When an engineered immune cell contacts non-target cells, the blocking receptors and activating receptors bind to their cognate activating ligands and blocking ligands expressed on the non-target cell. As explained, this causes the blocking signal to inhibit the activating signal. Further, activation of the blocking receptors causes reduced surface expression of the activating receptors. The activating receptors may be internalized, such that they are no longer on the surface of the immune cell and able to interact with activating ligands. As a result, the threshold to trigger a cytotoxic response by the immune cell is raised. Thus, the immune cells may temporarily exhibit a reduced propensity to kill cells, which can increase the therapeutic window of the cells.
[0171] As shown in FIG. 3, when the immune cell contacts a target cell, this reduced surface expression of the activating receptor does not occur and/or is reversed. Thus, when the immune cell encounters a target cell, the activating receptors bind to activating ligands. This provides the activating signal, but also causes the immune cell to reverse the reduced surface expression of the activating receptors. When the activating receptors are expressed on the surface of the immune cell at higher numbers, the activation threshold to trigger the cytotoxic response is reduced. Thus, immune cells in contact with target cells may temporarily exhibit an increased propensity to kill cells.
[0172] In certain immune cells of the disclosure, the reduced and/or regained expression of the activating receptor can be localized to a region of the immune cell surface proximate to a target or non-target cell. Thus, returning to FIG. 3, when the immune cell contacts a non-target cells, reduction of the activating receptors occurs in regions 303 proximate to the non-target cells. This can desensitize the immune cell in the regions 303 proximate to each non-target cell, which raises the activation threshold to trigger the cytotoxic response. Similarly, the immune cell can contact a target cell, and reduced surface expression of the activating receptor is reversed and/or does not occur in a region(s) 305 proximate to the target cell(s). This allows the region 305 proximate to the target cell to experience a local activation signal sufficient to trigger a localized cytotoxic response.
[0173] Advantageously, these localized responses can occur as an immune cell simultaneously and/or sequentially contacts target and non-target cells. Thus, as shown in FIG. 3, the immune cells can provide an activating signal localized to a region 305 proximate to a target cell, while also modulating expression of the activating receptor to reduce the activation threshold in the same region. Simultaneously, the immune cell can provide localized blocking signals and localized, reduced expression of the blocking receptor.
[0174] Reducing surface expression of the activating receptors. when not in contact with target cells. confers several advantages to the immune cells of the present disclosure. For example, if an immune cell circulates away from target cells, such as in a tumor, the immune cell is presumably more likely to contact non-target cells. By reducing the surface expression of the activating receptor in response to a lack of target cells, the immune cell increases its activation threshold, which can temporarily reduce the propensity of the immune cell to trigger a cytotoxic response. This designed feature of the engineered immune cells acts as a "safe mode", which enhances the safety and protective effects provided by the "AND NOT" Boolean logic, and further limits deleterious effects caused by the immune cells.
[0175] Further, while in this "safe mode", fewer activating receptors are available to activate. Thus, the immune cells of the present disclosure are less likely to experience chronic activation or ligand-independent tonic signaling. As a result, the immune cells are less susceptible to exhaustion, differentiation, and activation-induced immune cell death, while concurrently exhibiting high generation and persistence.
[0176] An additional and important feature of this reduced expression is that it does not extend to the engineered blocking receptors. Only the engineered activating receptors experience appreciable amounts of reduced expression. This ensures the safety profile of the immune cells of the present disclosure is maintained.
[0177] Thus, the present disclosure provides an engineered immune cell with an activating receptor and blocking receptor expressed on a surface of the engineered immune cell, wherein binding of the activating receptor to an activating ligand on a target cell promotes a cytotoxic response by the engineered immune cell, and binding of the blocking receptor to a blocking ligand causes the engineered immune cell to exhibit reduced surface expression of the activating receptor.
[0178] The present disclosure also provides a method for treating a cancer that includes providing an engineered immune cell to a patient, wherein the engineered immune cell comprises an activating receptor and a blocking receptor, each expressed on a surface of the engineered immune cell. When the engineered immune cell encounters a tumor cell of the patient, the activating receptor binds to an activating ligand on the tumor cell while the blocking receptor remains unbound, thereby promoting a cytotoxic response by the engineered immune cell that results in a cytotoxic effect on the tumor cell. When the engineered immune cell encounters a normal cell of the patient the blocking receptor binds to a blocking ligand on the normal cell and causes the engineered immune cell to exhibit reduced surface expression of the activating receptor, thereby causing a signal from the blocking receptor to dominate a signal from the activating receptor and prevent the cytotoxic response by the engineered immune cell.
[0179] Micro-Clusters
[0180] A further advantageous feature of the engineered immune cells disclosed herein is that the cells and receptors can be designed such that the activating and blocking receptors form micro-clusters on the surface of the immune cell. This ability to form micro-clusters provides an engineered immune cell with the ability to sense its proximity to target/non-target cells and provide an appropriate, localized response.
[0181] FIG. 20 shows a schematic of the micro-clustering behavior. When an immune cell encounters a target or non-target cell, its activating/blocking receptors bind to cognate ligands on the encountered cell(s). Cross-talk between these bound receptors and unbound receptors on the surface of the immune cell causes the unbound receptors to diffuse to a region on the immune cell surface proximate to the encountered cell(s). When the receptors diffuse into this region, they form a micro-cluster in which the ligand binding domains of the receptors locate in an activation synapse between the immune cell and the encountered cell(s).
[0182] Forming a micro-cluster with both activating and blocking receptors ensures that, when the blocking receptors are activated in the presence of an appropriate ligand on a non-target cell, the blocking signal is triggered proximate to the activation signal. This ensures that the blocking receptors can provide a localized inhibitory effect on the activation signal, thereby protecting the non-target cell. Thus, the micro-clusters enhance the "AND NOT" Boolean logic conferred by the activating and blocking receptors.
[0183] Advantageously, the engineered immune cells can be configured such that the activating and/or blocking ligands on target and/or non-target cells to experience a similar clustering effect on the surface of the encountered cell(s). Unbound activating and blocking ligands diffuse into an area on the target/non-target cell surface proximate to the immune cell, and become available for binding to a cognate receptor in the activation synapse.
[0184] Receptors are held in place on the surface of the immune cell by binding to cognate ligands in the activation synapse. This ensures that the receptors remain confined to a micro-cluster while the immune cell is in contact with a target/non-target cell. Maintaining the receptors within a micro-cluster helps assure that adequate numbers of activating and/or blocking receptors are within a region proximate to an encountered cell(s) to provide the requisite activating or blocking signal. It also increases the relative strength of both the activating and blocking receptors, which widens the therapeutic window of the immune cells of the disclosure.
[0185] The ability of the receptors to form micro-clusters also enhances the localized, reduced expression of the activating receptors when an immune cell encounters a non-target cell. By bringing activating and blocking receptors in close proximity, e.g., within the confines of a micro-cluster, the effect of cross-talk between the receptors is increased. This cross-talk leads to localized, reduced expression of the activating receptors in the micro-cluster.
[0186] Thus, the present disclosure provides an engineered immune cell comprising activating and blocking receptors on a surface of the engineered immune cell. When the engineered immune cell encounters a tumor cell, a first plurality of the activating receptors diffuse into a first region on the surface of the engineered immune cell and form a first micro-cluster proximal to the tumor cell that promotes a cytotoxic response by the engineered immune cell that results in cytotoxic effects on the tumor cell. When the engineered immune cell encounters a normal cell, a second plurality of the activating and blocking receptors diffuse into a second region on the surface of the engineered immune cell and form a second micro-cluster proximal to the normal cell, wherein the blocking receptors in the second micro-cluster inhibit cytotoxic effects on the normal cell.
[0187] The present disclosure also includes a method for treating cancer, the method comprising providing an engineered immune cell to a patient, the engineered immune cell comprising activating and blocking cell-surface receptors. When the engineered immune cell encounters a normal cell, a first plurality of the activating and blocking receptors collect into a micro-cluster within a region of the cell-surface of the engineered immune cell proximal to the normal cell. Binding of one of the blocking receptors in the micro-cluster to a blocking ligand on the normal cell inhibits breakup of the micro-cluster. The engineered immune cell kills tumor cells that exhibit an activating ligand bound by the activating receptor and do not exhibit the blocking ligand such that the blocking receptor remains unbound.
[0188] Multiplex and Localized Signaling
[0189] The engineered immune cells of the present disclosure have been designed to exhibit multiplex and localized activity. A shown in FIG. 21 an engineered immune cell 103 can simultaneously contact both target cells 121 and non-target cells 109. On regions of the immune cell 103 surface proximate to a non-target cell, the activating receptors 107 and blocking receptors 105 bind to activating ligands 111 and blocking ligands 113 on the non-target cell. As a result, a localized blocking signal inhibits a cytotoxic response 125 by the immune cell on the proximate non-target cell. Simultaneously or sequentially, the immune cell 103 can contact a target cell 121. The activating receptor 107 binds to the activating ligand 111 on the target cell 121. This causes a localized cytotoxic response 125, which may release cytotoxic granules 2103. The cytotoxic response only targets the target cell 121. The localized inhibition of the cytotoxic response in areas proximate to the non-target cells 109 protects them from an undesired immune response.
[0190] Thus, the present disclosure provides an engineered immune cell that includes activating and blocking receptors on the surface of the cell. When the engineered immune cell encounters a tumor cell and a healthy cell, a first region of the activating and blocking receptors form proximal to the healthy cell and blocking receptors in the first region inhibit cytotoxic effects on the healthy cell. Simultaneously, a second region of the activating and blocking receptors form proximal to the tumor cell and promotes a cytotoxic response by the engineered immune cell that exhibits cytotoxic effects on the tumor cell.
[0191] The present disclosure also provides a method for treating cancer that includes providing an engineered immune cell to a patient. The engineered immune cell has activating and blocking cell-surface receptors. When the engineered immune cell encounters a tumor cell and a healthy cell of the patient, a first set of the activating and blocking receptors collect into a first cell-surface region of the engineered immune cell proximal to the healthy cell in which the blocking receptors inhibit cytotoxic effects of the engineered immune cell on the healthy. Simultaneously, a second set of the activating and blocking receptors collect into a second cell-surface region of the engineered immune cell proximal to the tumor cell in which the activating receptors promote a cytotoxic response by the engineered immune cell that kills the tumor cell.
[0192] Dominant Blocking Receptors
[0193] The engineered immune cells of the present disclosure can be configured to have blocking receptors that produce a blocking signal that can overwhelm and fully inhibit the activating signal from the activating receptors.
[0194] As shown in FIG. 22, which is explained in greater detail below, the cells can be designed to express activating and blocking receptors that, when expressed at equivalent concentrations, it takes less blocking antigen relative activating antigen to inhibit the activating signal. Thus, each blocking receptor can inhibit the activating signal of one or more activating receptors. This means that the blocking signal from a single blocking receptor can dominate and inhibit the activating signal from a single activating receptor. This helps solidify the safety profile of the "AND NOT" Boolean logic used by the immune cells of the present disclosure.
[0195] As shown in FIG. 23, the blocking receptors can be engineered to provide minimal ligand-independent blocking activity on the activating receptors. As a corollary, the blocking receptors can provide overwhelmingly ligand-dependent activity.
[0196] Thus, the immune cells of the present disclosure may include blocking receptors that provide, for example, a less than 10.times. shift in the EC.sub.50 of the activating receptors when the immune cells are contacted with the activating ligand in the absence of the blocking ligand. The immune cells of the present disclosure can provide a less than 3.times. shift in the EC.sub.50 of the activating receptors when the immune cells are contacted with the activating ligand in the absence of the blocking ligand.
[0197] Since the blocking receptors of the present disclosure can provide an overwhelmingly ligand-dependent, dominate blocking signal, the levels of activating ligand and blocking ligand expressed on a non-target cell can be used to inform the appropriate levels of activating and blocking receptor expressed by the engineered immune cells of the present disclosure. The dominate blocking signal provides assurance that ligand quantity can be used as a proxy to inform the levels of activating and blocking receptors that should be expressed in order to assure sufficient inhibition. Moreover, the ligand-dependent nature of the blocking signal means that the expression of the blocking receptor will require little to no adjustment to prevent unintended increases to the EC.sub.50 of the activating receptors in the absence of the blocking ligand.
[0198] Thus, the present disclosure provides methods for producing engineered immune cells that express activating and blocking receptors based on a ratio of a quantity of activating ligands to a quantity of blocking ligands that are expressed in a normal, non-tumor cell of a patient. The activating and blocking receptors may be expressed at a ratio based upon the ratio of the quantity of activating ligands to the quantity of blocking ligands expressed by the normal cell.
[0199] The present disclosure also provides an engineered immune cell with an activating receptor on a surface of the engineered immune cell. Binding of the activating receptor to an activating ligand on a target cell causes the activating receptor to trigger an activating signal that promotes a cytotoxic response by the engineered immune cell. The cell also has a blocking receptor. Binding of the blocking receptor to a blocking ligand on a target cell causes the blocking receptor to trigger an inhibitory signal stronger than the activating signal such that the inhibitory signal dominates and blocks the activating signal from the activating receptor, thereby preventing a localized cytotoxic response by the engineered immune cell.
[0200] The disclosure further includes a method for treating cancer, the method comprising providing an engineered immune cell to a patient. The engineered immune cell comprises an activating receptor and a blocking receptor, each expressed on a surface of the engineered immune cell. When the engineered immune cell encounters a tumor cell, the activating receptor binds to an activating ligand on the tumor cell and the activating receptor triggers an activating signal in the engineered immune cell that promotes a cytotoxic response by the engineered immune cell that results in a cytotoxic effect on the tumor cell. When the engineered immune cell encounters a normal cell, the activating receptor binds to the activating ligand on the normal cell and the blocking receptor binds to a blocking ligand on the normal cell. This leads to the activating receptor triggering an activating signal in the engineered immune cell and the blocking receptor triggering an inhibitory signal in the engineered immune cell that is stronger than the activating signal, such that the inhibitory signal dominates and blocks the activating signal from the activating receptor, thereby preventing a localized cytotoxic response by the engineered immune cell.
[0201] Modulating Activating and Blocking Signals of Receptors
[0202] The present disclosure also provides strategies for engineering receptors in a manner that modulates receptor signal strength to ensure strong activation signals and sufficient blocking signals.
[0203] FIG. 24 shows a schematic of the blocking and activating receptors of the present disclosure. In general, each type of receptor can comprise four parts, the ligand binding domain ("LBD"), the hinge ("H"), the transmembrane domain ("TM"), and the intracellular domain ("ICD"). Each of these four parts can have an impact on the structure-activity relationship of each receptor. By altering these parts, the behavior of each receptor can be finely tuned to exhibit desired activity. For example, altering these parts can cause the receptors to exhibit varying specificity and affinity for cognate ligands, strengths of activating and/or blocking signals, levels of cross-talk between receptors, and/or receptor surface expression.
[0204] The hinge is an extracellular domain between a receptor's extracellular ligand binding domain and transmembrane domain and/or intracellular domain. Surprisingly, the Inventors of the present disclosure have found that, for the activating receptor, a wide variety of hinge lengths and sequences are tolerated. Thus, changes to the activating receptor hinge can provide relatively little change to the structure activity relationship of the activating receptor. For example, changes to the hinge were shown to cause only minimal contributions to the activating receptors' EC.sub.50, baseline signaling, and maximum signaling.
[0205] In contrast, the Inventors of the present disclosure have found that modifications to the hinge can be used to modulate the activity of the blocking receptor, including increases in the surface expression of the blocking receptor and blocking signal strength. Thus, a feature of the present disclosure is that the blocking receptor can be designed using interchangeable hinges that connect an extracellular ligand binding domain to a transmembrane domain and/or an intracellular domain.
[0206] The hinges can be designed to have different lengths and flexibilities. As shown in FIG. 24, flexible hinges inure blocking receptors with a greater blocking strength compared to rigid hinges. However, a greater change to blocking strength can be provided by changing the length of the hinge. As shown in FIG. 25, lengthening a hinge from about 25 amino acids to about 35 amino acids confers a significant increase in blocker strength. This increase becomes more dramatic, as the hinge length approaches 65 amino acids in length. As also shown in FIG. 25, the relative flexibility/rigidity of a hinge also impacts the strength of a blocker. Although, this impact is reduced compared to that provided by the hinge length.
[0207] Thus, the blocking receptors can be designed with longer and/or more flexible hinges to increase the strength of the blocking receptor's signal or surface expression. In contrast, the blocking receptor can be engineered with shorter and/or more rigid hinges to decrease the strength of the blocking receptor's signal or surface expression. The blocking receptor can be configured to use a hinge selected from a group of hinges that have a known impact on the EC.sub.50 of the activating ligand for the activating receptor to cause the immune cell to trigger a cytotoxic response. This allows pairs of blocking and activating receptors to be chosen or engineered to exhibit a desired level of activation/inhibition.
[0208] Advantageously, as the activating receptor can tolerate a wide variety of hinges, the activating receptors can be engineered with hinges that interact with a blocking receptor at the structural level. Different activator hinges may provide varying levels of interaction with a specific blocker. Thus, various activator hinges can be tested with a particular blocking receptor to determine the identity of activating receptor hinges that lead to increased blocking by a particular blocking receptor. Such testing may include, for example, changing the hinge of an activating receptor and measuring the blocking receptor strength, i.e., the IC.sub.50, of a particular blocking receptor when a particular activating receptor hinge is used.
[0209] The Inventors of the present disclosure found that the identity of the ligand binding domain of the engineered activating receptors has the greatest impact on the structure activity relationship of the receptors. As shown in FIG. 26, different ligand binding domains, which all bind to the same activating ligand, provide effects on the receptors' EC.sub.50 that differ by orders of magnitude. In contrast, the identity of the hinge and/or intracellular domain provides a smaller impact on the receptors' EC.sub.50.
[0210] As with the LBD of the activating receptor, the identity of the blocking receptor LBD can have large effects on the IC.sub.50 of the engineered immune cells of the present disclosure. This is shown in FIG. 27, where several different ligand binding domains were tested for their effect on the IC.sub.50 of engineered immune cells. Interestingly, the Inventors of the present disclosure found that when a ligand binding domain was switched between an activating receptor and blocking receptor, the LBD provided a correlative effect on the IC.sub.50 and EC.sub.50 of an immune cell.
[0211] The Inventors of the present disclosure found that a wide variety of commonly used intracellular domains have relatively minimal impacts on the EC.sub.50 of the activating receptor. Conversely, the Inventors discovered that the intracellular domain of the blocking receptor can have large effects on the strength of the blocking signal. Thus, the intracellular domain of the blocking receptor can be changed to modulate the strength of the blocking signal to ensure adequate inhibition. As shown in FIG. 32, changing the intracellular domain of the blocking receptor can have wide ranging effects on the strength of the blocking signal.
[0212] Receptor Cross-Talk
[0213] The present disclosure also provides engineered immune cells in which the activity of the activating and blocking receptors is modulated via cross-talk between the receptors.
[0214] FIGS. 33-34 show the impact receptor cross-talk can have on the ability of the blocking receptor to inhibit the activation signal. Engineered immune cells were created with one of five different activating receptors. Though the activating receptors differed between the cell lines, each targeted the same activating ligand, epidermal growth factor receptor (EGFR), using a different antibody. As shown by the five graphs at the bottom in FIGS. 33-34, each of the different activating receptors provided the immune cells with equivalent abilities to kill target cells. Then, immune cells were created that had one of the five activating receptors and the same blocking receptor. Addition of the blocker caused some of the immune cells, like CT486, to exhibit a significant decrease in the cells' ability to kill target cells. The blocking receptors also provided varying effects in the ability of the immune cells to inhibit the activating signal in the presence of non-target cells.
[0215] This disparity in behavior between different activating receptors and a blocking receptor can be attributed to cross-talk between the receptors.
[0216] Thus, the present disclosure provides an engineered immune cell that includes an activating receptor that triggers a cytotoxic signal that promotes a cytotoxic response of the engineered immune cell when the activating receptor binds to an activating ligand of a target cell, a blocking receptor that sends an interfering signal that inhibits the cytotoxic response of the engineered immune cell when the blocking receptor binds a blocking ligand, and cross-talk between the activating receptor and the blocking receptor that affects an activation threshold for the cytotoxic response.
[0217] The disclosure also includes a method for treating cancer, the method includes providing an engineered immune cell to a patient. The engineered immune cell comprises an activating receptor and a blocking receptor, each expressed on a surface of the engineered immune cell. The activating receptor triggers a cytotoxic signal that promotes a cytotoxic response of the engineered immune cell when the activating receptor binds to an activating ligand of a target cell. The blocking receptor sends an interfering signal that inhibits the cytotoxic response of the engineered immune cell when the blocking receptor binds a blocking ligand. Cross-talk between the activating receptor and the blocking receptor affects an activation threshold for the cytotoxic response.
[0218] Modulating Receptor Proximity
[0219] The Inventors of the present disclosure made the surprising discovery that the strength of the blocking signal can increase as the distance between activating and blocking receptors decreases, and that when the receptors are separated by a particular average minimum distance, the blocking signal provides a maximum inhibitory effect on an activating receptor. Thus, the present disclosure provides engineered immune cells, and methods of making using engineered immune cells, with activating and blocking receptors spaced apart by at least a minimum average distance on the immune cell surface. The present Inventors also discovered that when activating and blocking receptors are within a certain, close proximity to one another, the activation of the blocking receptor may cause the blocking receptor to invert and provide an activating signal.
[0220] In certain engineered immune cells of the present disclosure, this average minimum distance is between about 100 to 200, 200 to 300, 300 to 400, 400 to 500, 500 to 600, 600 to 700, 700 to 800, 800 to 900, or 900 to 1000 angstroms.
[0221] As shown in FIG. 35, the Inventors devised several strategies to ensure that the activating and blocking receptors are spaced at a distance to ensure a high blocking signal strength. For example, the receptors can be attached via a C-terminal or N-terminal bridge. Alternatively or in addition, the receptors can be designed to have substituent groups or amino acids with opposing charges to enforce spacing between receptors. Bulky substituent groups or amino acids can also be used to cause steric effects that prevent the receptors from diffusing too close to one another.
[0222] Thus, the present disclosure provides engineered immune cells with activating and blocking receptors that possess physiochemical properties that maintain an average minimum distance between the receptors on the cell surface. Physiochemical properties may include, for example, opposing charges on each of the cell surface activating receptor and the cell surface blocking receptor, non-covalent interactions, van der Walls interactions, and/or steric effects.
[0223] The present disclosure also or alternatively provides engineered immune cells that have a spacer operably associated with an activating and blocking receptor on the cell surface that is configured to maintain an average minimum distance between the receptors on the cell surface. The spacer may covalently or non-covalently link the activating and blocking receptors. The spacer may include C- or N-terminal fusion that links the receptors. The spacer may alternatively or in addition include two moieties that allow non-covalent binding between the LBD, ICD, and/or hinge of each receptor. The spacer may also or alternatively include a non-covalent interacting motif that mediates protein-protein interaction, such as a leucine zipper.
[0224] The distance between the activating and blocking receptors may be controlled by using a spacer that includes a linker. Any linker may be used, and many fusion protein linker formats are known. For example, the linker may be flexible or rigid. Non-limiting examples of rigid and flexible linkers are provided in Chen et al. (Adv Drug Deliv Rev. 2013; 65(10):1357-1369).
[0225] Non-limiting exemplary rigid linkers include alpha helix-forming linkers with the sequence of (EAAAK).sub.n and (EAAAK).sub.nA, wherein n=1-10. Another exemplary rigid linker is a proline rich linker having the sequence (XP).sub.n where X is any amino acid and is preferably selected from A, G, and E and n=1-10, and glycine-serine linkers with a high ratio of serine to glycine.
[0226] The ligand binding domains described herein may be linked to each other in a random or specified order. The ligand binding domains described herein may be linked to each other in any orientation of N to C terminus.
[0227] Optionally, a short oligo- or polypeptide linker, for example, between 2 and 40 amino acids (e.g., 2, 3, 4, 5, 6, 7, 8, 9, or 10 amino acids) in length may form the linkage between the domains. The linker is a peptide of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30 or more than 30 amino acid residues.
[0228] Non-limiting examples of amino acids found in linkers include Gly, Ser, Glu, Gin, Ala, Leu, Iso, Lys, Arg, Pro, and the like.
[0229] The linker may be [(Gly).sub.n1Ser]n2, where n1 and n2 may be any number (e.g. n1 and n2 may independently be 1, 2, 4, 5, 6, 7, 8, 9, 10 or more than 10). The linker may be flexible polypeptide linker that is a Gly/Ser linker and comprises the amino acid sequence (Gly-Gly-Ser), (Gly-Gly-Gly-Ser), or (Gly-Gly-Gly-Gly-Ser) which can be repeated n times, where n is a positive integer equal to or greater than 1. For example, n-1, n-2, n-3, n-4, n-5, n-6, n-7, n-8, n=9 and n=10. The linker may include multiple repeats of (Gly Gly Ser), (Gly Ser) or (Gly Gly Gly Ser). Also included within the scope of the invention are linkers described in WO2012/138475 (incorporated herein by reference). In some embodiments, the flexible polypeptide linkers include, but are not limited to, GGS, GGGGS (SEQ ID NO: 226), GGGGS GGGGS (SEQ ID NO: 227), GGGGS GGGGS GGGGS (SEQ ID NO: 228), GGGGS GGGGS GGGGS GG (SEQ ID NO: 229) or GGGGS GGGGS GGGGS GGGGS (SEQ ID NO: 230). In some embodiments, the linkers include multiple repeats of (Gly Gly Ser), (Gly Ser) or (Gly Gly Gly Ser (SEQ ID NO: 231)).
[0230] The linker sequence may comprise a long linker (LL) sequence. The long linker sequence may comprise GGGGS, repeated four times. Such a linker may be used to link intracellular domains in a TCR alpha fusion protein of the disclosure. The long linker sequence may comprise GGGGS, repeated three times. The linker sequence may comprise a short linker (SL) sequence. The short linker sequence may comprise GGGGS. A glycine-serine doublet can be used as a suitable linker. Alternatively, domains are fused directly to each other via peptide bonds without use of a linker.
[0231] By reducing the G:S ratio in a Gly-Ser linker, the linker can be made more rigid.
[0232] The strength of the blocking signal may be the strongest when the activating and blocking receptors are separated by a distance of 0-1000 angstroms. The strength of the blocking signal may be the strongest when the activating and blocking receptors are separated by a distance of 0-50 angstroms, 50-100 angstroms, 100-200 angstroms, 200-300 angstroms, 300-400 angstroms, 400-500 angstroms, 500-600 angstroms, 600-700 angstroms, 700-800 angstroms, 800-900 angstroms, or 900-1000 angstroms. Preferably, the distance is about 200 angstroms.
[0233] Thus, the present disclosure provides an engineered immune cell with an activating receptor on the cell surface that triggers a cytotoxic signal that promotes a cytotoxic response of the engineered immune cell when the activating receptors binds to a first ligand on a target cell; and a blocking receptor on the cell surface that sends an interfering signal that inhibits the cytotoxic response of the engineered immune cell when the blocking receptor binds a second ligand of the target cell. Proximity of the blocking receptor to the activating receptor effects an activation threshold for the cytotoxic response, and the activating and blocking receptors physiochemical properties favoring interaction with one another, such that the receptors are spaced apart at an average distance on the immune cell surface.
[0234] The present disclosure also provides a method for treating cancer that includes providing an engineered immune cell to a patient, wherein the engineered immune cell comprises an activating receptor and a blocking receptor, each expressed on a surface of the engineered immune cell. The activating receptor triggers a cytotoxic signal that promotes a cytotoxic response of the engineered immune cell when the activating receptor binds a first ligand of a target cell, and the blocking receptor sends an interfering signal that inhibits the cytotoxic response of the engineered immune cell when the blocking receptor binds a second ligand of the target cell. Proximity of the blocking receptor to the activating receptor affects an activation threshold for the cytotoxic response, and the activating and blocking receptors physiochemical properties favoring interaction with one another, such that the receptors are spaced apart at an average distance on the immune cell surface.
[0235] The present disclosure also provides a method of producing an engineered immune cell that includes producing an engineered immune cell that expresses activating receptors and blocking receptors based on a determined distance between the receptors, wherein an activation threshold for a cytotoxic response by the immune cell is maximized when the receptors are separated on the cell surface by the determined average distance.
[0236] Receptor Types
[0237] The present disclosure provides immune cells comprising activating and blocking receptors, which may independently comprise a chimeric antigen receptor (CAR) a T cell receptor (TCR) or a combination of components from CARs or TCRs.
[0238] As shown in FIG. 28, the immune cells of the present disclosure can use receptors that comprise various combinations of TCRs and CARs. For example, as shown in FIG. 29, both a blocking CAR and blocking TCR can effectively inhibit the activation signal of a TCR-based activating receptor.
[0239] Moreover, the receptors of the present disclosure can effectively use components of both CARs and TCRs to achieve desired receptor activity.
[0240] As shown in FIG. 30, the ligand binding domain of a CAR activating receptor can be used with the intracellular domain of a TCR activating receptor, and still provide a target-specific activation signal.
[0241] As shown in FIG. 31, the various components of TCRs and CARs can be interchanged to provide receptors with activities beyond blocking and activating receptors. For example, the components can be used to create Inverter TCRs, Super TCRs, Parasitic TCRs, and Molecular Integrators.
[0242] In some embodiments, one or more of the blocking receptor and activating receptor comprise a CAR. All CAR architectures are envisaged as within the scope of the instant disclosure.
[0243] The CARs of the present disclosure comprise an extracellular hinge region. Incorporation of a hinge region can affect cytokine production from CAR-T cells and improve expansion of CAR-T cells in vivo. Exemplary hinges can be isolated or derived from IgD and CD8 domains, for example IgG1, CD8.alpha., or CD28, such as those disclosed by the Inventors of the present disclosure in PCT International Application No. PCT/US2020/045250 and PCT/US2021/030149, which are incorporated herein by reference in their entirety.
[0244] For example, exemplary hinges used in the receptors disclosed herein, which are isolated or derived from CDSa or CD28 include a CDSa hinge comprising an amino acid sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NOS: 1 or 3 or encoded by SEQ ID NO: 4.
[0245] The CARs of the present disclosure can be designed to comprise a transmembrane domain that is fused to the hinge of the CAR. The transmembrane domain may be naturally associated with one of the domains of the CAR, such as the hinge or intracellular domain. For example, a CAR comprising a CD28 co-stimulatory domain might also use a CD28 transmembrane domain. In some instances, the transmembrane domain can be selected or modified by amino acid substitution to avoid binding of such domains to the transmembrane domains of the same or different surface membrane proteins to minimize interactions with other members of the receptor complex.
[0246] The transmembrane domain may be derived either from a natural or synthetic source. When the source is natural, the domain may be derived from any membrane-bound or transmembrane protein. Transmembrane regions may be isolated or derived from (i.e., comprise at least the transmembrane region(s) of) the alpha, beta, or zeta chain of the T-cell receptor, CD28, CD3 epsilon, CD45, CD4, CD5, CD8, CD9, CD16, CD22, CD33, CD37, CD64, CD80, CD86, CD134, CD137, CD154, or from an immunoglobulin such as IgG4.
[0247] Alternatively, the transmembrane domain may be synthetic, in which case it can comprise predominantly hydrophobic residues such as leucine and valine. Certain transmembrane domains may comprise a triplet of phenylalanine, tryptophan and valine found at each end of a synthetic transmembrane domain. Optionally, a short oligo- or polypeptide linker, preferably between 2 and 10 amino acids in length may form the linkage between the transmembrane domain and the cytoplasmic signaling domain of the CAR. A glycine-serine doublet provides a particularly suitable linker. The CARs may comprise a CD28 transmembrane domain or an IL-2Rbeta transmembrane domain, such as those disclosed by the present Inventors in PCT International Application No. PCT/US2020/045250 and PCT/US2021/030149, incorporated herein by reference.
[0248] For example, the CD28 transmembrane domain may comprise an amino acid sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 5. The CD28 transmembrane domain may be encoded by a nucleotide sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to SEQ ID NO: 6. An exemplary IL-2R beta transmembrane domain as disclosed here may comprise an amino acid sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to SEQ ID NO: 7. In some aspects, an exemplary IL-2Rbeta transmembrane domain is encoded by a nucleotide sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 8.
[0249] The intracellular signaling domains of CARs used as parts of the activating or blocking receptors are responsible for activation of at least one of the normal effector functions of the immune cell in which the CAR has been placed. The term "effector function" refers to a specialized function of a cell. Effector functions of a regulatory T cell, for example, include the suppression or downregulation of induction or proliferation of effector T cells. Thus, the term "intracellular signaling domain" refers to the portion of a protein which transduces the effector function signal and directs the cell to perform a specialized function.
[0250] While usually an entire intracellular signaling domain can be employed, in many cases it is not necessary to use the entire domain. To the extent that a truncated portion of the intracellular signaling domain is used, such truncated portion may be used in place of the intact chain as long as it transduces the effector function signal. In some cases, multiple intracellular domains can be combined to achieve the desired functions of CAR-T cells of the instant disclosure. The term intracellular signaling domain is thus meant to include any truncated portion of one or more intracellular signaling domains sufficient to transduce the effector function signal.
[0251] Examples of intracellular signaling domains for use in the CARs of the instant disclosure include the cytoplasmic sequences of the T cell receptor (TCR) and co-receptors that act in concert to initiate signal transduction following antigen receptor engagement, as well as any derivative or variant of these sequences and any synthetic sequence that has the same functional capability. In certain receptors of the disclosure, the intracellular activation domain ensures that there is T cell receptor (TCR) signaling necessary to activate the effector functions of the CAR-T cell.
[0252] The CAR intracellular domains of the instant disclosure may comprise at least one cytoplasmic activation domain. The at least one cytoplasmic activation domain can be a CD247 molecule (CD3) activation domain, a stimulatory killer immunoglobulin-like receptor (KIR) KIR2DS2 activation domain, or a DNAX-activating protein of 12 kDa (DAP12) activation domain, such as those disclosed by the present inventors in PCT International Application No. PCT/US2020/045250 and PCT/US2021/030149, which are incorporated by reference.
[0253] For example, the CD3z activation domain comprises an amino acid sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to SEQ ID NO: 9 and/or encoded by a nucleotide sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 10.
[0254] It is known that signals generated through a TCR alone can be insufficient for full activation of a T cell, and that a secondary or co-stimulatory signal may be also required. Thus, T cell activation can be mediated by two distinct classes of cytoplasmic signaling sequence: those that initiate antigen-dependent primary activation through the TCR (primary cytoplasmic signaling sequences) and those that act in an antigen-independent manner to provide a secondary or co-stimulatory signal (secondary cytoplasmic signaling sequences).
[0255] Primary cytoplasmic signaling sequences regulate primary activation of the TCR complex either in a stimulatory or inhibitory manner. Exemplary cytoplasmic signaling sequences are disclosed by the present Inventors in PCT International Application No. PCT/US2020/045250, which is incorporated by reference.
[0256] Primary cytoplasmic signaling sequences that act in a stimulatory manner may contain signaling motifs which are known as immunoreceptor tyrosine-based activation motifs or ITAMs. In certain receptors of the disclosure, the cytoplasmic signaling domain contains 1, 2, 3, 4, or 5 ITAMs.
[0257] In certain receptors of the disclosure, the cytoplasmic domain comprises a CD3.zeta. activation domain. The CD3.zeta. activation domain may comprise a single ITAM, two ITAMs, or three ITAMs.
[0258] Further examples of ITAM containing primary cytoplasmic signaling sequences that can be used in the CARs of the instant disclosure include those derived from TCR.zeta., FcR.gamma., FcR.beta., CD3.gamma., CD3.delta., CD3.epsilon., CD3.zeta., CD5, CD22, CD79a, CD79b, and CD66d. It is particularly preferred that cytoplasmic signaling molecule in the CAR of the instant invention comprises a cytoplasmic signaling sequence derived from CD3.zeta..
[0259] In certain receptors of the disclosure, the cytoplasmic domain of the CAR may comprise the CD3.zeta. signaling domain by itself or combined with any other desired cytoplasmic domain(s). For example, the cytoplasmic domain of the CAR can comprise a CD3.zeta. chain portion and a co-stimulatory domain.
[0260] For example, the CD3z activation domain may comprise a single ITAM and comprises an amino acid sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 11 and/or encoded by a nucleotide sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to SEQ ID NO: 12.
[0261] The co-stimulatory domain refers to a portion of a CAR comprising the intracellular domain of a costimulatory molecule. A costimulatory molecule is a cell surface molecule, other than an antigen receptor or its ligands, that is required for an efficient response of lymphocytes to an antigen. In receptors of the disclosure, the costimulatory domain is selected from the group consisting of IL2R.beta., Fc Receptor gamma (FcR.gamma.), Fc Receptor beta (FcR.beta.), CD3g molecule gamma (CD3.gamma.), CD3.delta., CD3.epsilon., CD5 molecule (CD5), CD22 molecule (CD22), CD79a molecule (CD79a), CD79b molecule (CD79b), carcinoembryonic antigen related cell adhesion molecule 3 (CD66d), CD27 molecule (CD27), CD28 molecule (CD28), TNF receptor superfamily member 9 (4-1BB), TNF receptor superfamily member 4 (OX40), TNF receptor superfamily member 8 (CD30), CD40 molecule (CD40), programmed cell death 1 (PD-1), inducible T cell costimulatory (ICOS), lymphocyte function-associated antigen-1 (LFA-1), CD2 molecule (CD2), CD7 molecule (CD7), TNF superfamily member 14 (LIGHT), killer cell lectin like receptor C2 (NKG2C) and CD276 molecule (B7-H3) c-stimulatory domains, or functional fragments thereof.
[0262] The cytoplasmic domains within the cytoplasmic signaling portion of the CARs of the instant disclosure may be linked to each other in a random or specified order. Optionally, a short oligo- or polypeptide linker, for example between 2 and 10 amino acids in length may form the linkage. A glycine-serine doublet provides an example of a suitable linker.
[0263] The intracellular domains of CARs of the instant disclosure may include at least one co-stimulatory domain. The co-stimulatory domain may be isolated or derived from CD28.
[0264] An exemplary CD28 co-stimulatory domain comprises an amino acid sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 13 and/or encoded by a nucleotide sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 14.
[0265] The intracellular domain of the CARs of the instant disclosure may include an interleukin-2 receptor beta-chain (IL-2Rbeta or IL-2R-beta) cytoplasmic domain. The IL-2Rbeta domain may be truncated. The IL-2Rbeta cytoplasmic domain may comprise one or more STAT5-recruitment motifs, which may be outside the IL-2Rbeta cytoplasmic domain.
[0266] An exemplary IL-2Rbeta intracellular domain may comprise an amino acid sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 15 and/or encoded by a nucleotide sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 16.
[0267] Exemplary STAT5-recruitment motifs are provided by Passerini et al., (2008) STAT5-signaling cytokines regulate the expression of FOXP3 in CD4+CD25+ regulatory T cells and CD4+CD25+ effector T cells, International Immunology, Vol. 20, No. 3, pp. 421-431, and by Kagoya et al., (2018) A novel chimeric antigen receptor containing a JAK-STAT signaling domain mediates superior antitumor effects. Nature Medicine doi:10.1038/nm.4478, which are each incorporated herein by reference.
[0268] An exemplary STAT-recruitment motif used herein may consist of SEQ ID NO: 17.
[0269] In certain blocking receptors of the disclosure, the inhibitory signal is transmitted through the intracellular domain of the receptor. Thus, the blocking receptor may comprise an inhibitory intracellular domain.
[0270] The inhibitory intracellular domain may comprise an immunoreceptor tyrosine-based inhibitory motif (ITIM). The inhibitory intracellular domain comprising an ITIM can be isolated or derived from an immune checkpoint inhibitor such as CTLA-4 and PD-1. CTLA-4 and PD-1 are immune inhibitory receptors expressed on the surface of T cells, and play a pivotal role in attenuating or terminating T cell responses.
[0271] "ITIM" refers to a conserved sequence of amino acids with a consensus sequence provided in SEQ ID NO: 274. Exemplary ITIMs include, those having sequences of SEQ ID NOS: 67, 68, 69, and 70. In some embodiments, the intracellular domain comprises a sequence at least 95% identical to SEQ ID NOS: 71, 72, 73, 74, 75, or 76.
[0272] Inhibitory domains can also be isolated from human tumor necrosis factor related apoptosis inducing ligand (TRAIL) receptor and CD200 receptor 1.
[0273] The inhibitory domain may comprise an intracellular domain, a transmembrane or a combination thereof. Alternatively, the inhibitory domain comprises an intracellular domain, a transmembrane domain, a hinge region or a combination thereof. The inhibitory domain may contain an immunoreceptor tyrosine-based inhibitory motif (ITIM). The inhibitory domain comprising an ITIM can be isolated or derived from an immune checkpoint inhibitor such as CTLA-4 and PD-1.
[0274] Inhibitory domains can be isolated from human tumor necrosis factor related apoptosis inducing ligand (TRAIL) receptor and CD200 receptor 1. The inhibitory domain may be isolated or derived from a human protein, for example a human TRAIL receptor, CTLA-4, or PD-1 protein. In some embodiments, the TRAIL receptor comprises TR10A, TR10B or TR10D.
[0275] Endogenous TRAIL is expressed as a 281-amino acid type II trans-membrane protein, which is anchored to the plasma membrane and presented on the cell surface. TRAIL is expressed by natural killer cells, which, following the establishment of cell-cell contacts, can induce TRAIL-dependent apoptosis in target cells. Physiologically, the TRAIL-signaling system was shown to be essential for immune surveillance, for shaping the immune system through regulating T-helper cell 1 versus T-helper cell 2 as well as "helpless" CD8+ T-cell numbers, and for the suppression of spontaneous tumor formation.
[0276] The inhibitory domain may comprise an intracellular domain isolated or derived from a CD200 receptor. The cell surface glycoprotein CD200 receptor 1 (Uniprot ref: Q8TD46) represents another example of an inhibitory intracellular domain of the present invention. This inhibitory receptor for the CD200/OX2 cell surface glycoprotein limits inflammation by inhibiting the expression of proinflammatory molecules including TNF-alpha, interferons, and inducible nitric oxide synthase (iNOS) in response to selected stimuli.
[0277] The inhibitory domain may be isolated or derived from killer cell immunoglobulin like receptor, three Ig domains and long cytoplasmic tail 2 (KIR3DL2), killer cell immunoglobulin like receptor, three Ig domains and long cytoplasmic tail 3 (KIR3DL3), leukocyte immunoglobulin like receptor B1 (LIR1), programmed cell death 1 (PD1), Fc gamma receptor IIB (FcgRIIB), killer cell lectin like receptor K1 (NKG2D), CTLA-4, a domain containing a synthetic consensus ITIM, a ZAP70 SH2 domain (e.g., one or both of the N and C terminal SH2 domains), or ZAP70 KI_K369A (kinase inactive ZAP70).
[0278] The inhibitory domain may be isolated or derived from a human protein. The blocking receptor may comprise a cytoplasmic domain and transmembrane domain isolated or derived from the same protein. For example, an ITIM containing protein. The blocking receptor may comprise a cytoplasmic domain, a transmembrane domain, and an extracellular domain or a portion thereof isolated or derived isolated or derived from the same protein. The blocking receptor may comprise a hinge region isolated or derived from isolated or derived from the same protein as the intracellular domain and/or transmembrane domain.
[0279] In certain immune cells of the disclosure, one or more of the activating and blocking receptors comprise a T Cell Receptor (TCR).
[0280] A "TCR", sometimes also called a "TCR complex" or "TCR/CD3 complex" refers to a protein complex comprising a TCR alpha chain, a TCR beta chain, and one or more of the invariant CD3 chains (zeta, gamma, delta and epsilon), sometimes referred to as subunits.
[0281] The TCR alpha and beta chains can be disulfide-linked to function as a heterodimer to bind to peptide-MHC complexes. Once the TCR alpha/beta heterodimer engages peptide-MHC, conformational changes in the TCR complex in the associated invariant CD3 subunits are induced, which leads to their phosphorylation and association with downstream proteins, thereby transducing a primary stimulatory signal. In an exemplary TCR complex, the TCR alpha and TCR beta polypeptides form a heterodimer, CD3 epsilon and CD3 delta form a heterodimer, CD3 epsilon and CD3 gamma for a heterodimer, and two CD3 zeta form a homodimer.
[0282] The LBD of the activating or blocking receptors may be fused to an extracellular domain of a TCR subunit. The TCR subunit can be TCR alpha, TCR beta, CD3 delta, CD3 epsilon or CD3 gamma. Both the first and second ligand binding domains may be fused to the same TCR subunit in different TCR receptors. Alternatively, the first and second ligand binding domains are fused to different TCR subunits in different TCR receptors.
[0283] The LBD of the activating receptor and blocking receptor may each independently comprise an scFv domain or a V.beta.-only domain.
[0284] TCR subunits include TCR alpha, TCR beta, CD3 zeta, CD3 delta, CD3 gamma and CD3 epsilon. Any one or more of TCR alpha, TCR beta chain, CD3 gamma, CD3 delta or CD3 epsilon, or fragments or derivatives thereof, can be fused to one or more domains capable of providing a stimulatory signal of the disclosure, thereby enhancing TCR function and activity. Any one or more of TCR alpha, TCR beta chain, CD3 gamma, CD3 delta or CD3 epsilon, or fragments or derivative thereof, can be fused to an inhibitory intracellular domain of the disclosure.
[0285] The receptors of the present disclosure may comprise TCRs comprising a TCR variable domain. The TCR variable domain specifically binds to an antigen in the absence of a second TCR variable domain (a V.beta.-only domain).
[0286] The TCRs may comprise additional elements besides the TCR variable domain, including additional amino acid sequences, additional protein domains (covalently associated, non-covalently associated or covalently and non-covalently associated with the TCR variable domain), fusion or non-covalent association of the TCR variable domain with other types of macromolecules (for example polynucleotides, polysaccharides, lipids, or a combination thereof), fusion or non-covalent association of the TCR variable domain with one or more small molecules, compounds, or ligands, or a combination thereof. Any additional element, as described, may be combined provided that the TCR variable domain is configured to specifically bind the epitope in the absence of a second TCR variable domain.
[0287] TCRs comprising a V.beta.-only domain as described herein may comprise a single TCR chain (e.g. .alpha., .beta., .gamma., or .delta. chain), or may comprise a single TCR variable domain (e.g. of .alpha., .beta., .gamma., or .delta. chain). If a TCR is a single TCR chain, then the TCR chain comprises a transmembrane domain, a constant (or C domain) and a variable (or V domain), but does not comprise a second TCR variable domain. The TCRs may comprise or consist of a TCR .alpha. chain, a TCR .beta. chain, a TCR .gamma. chain or a TCR .delta. chain. The TCRs may be a membrane bound proteins. The TCRs may alternatively be membrane associated proteins.
[0288] The TCRs may use a surrogate .alpha. chain that lacks a V.alpha. segment, which forms activation competent TCRs complexed with the six CD3 subunits. The TCRs may function independently of a surrogate .alpha. chain that lacks a V.alpha. segment. For example, one or more TCRs may be fused to transmembrane (e.g., CD3 and CD28) and intracellular domain proteins (e.g., CD3, CD28, and/or 4-1BB) that are capable of activating T cells in response to antigen.
[0289] TCRs may comprise one or more single TCR chains fused to the V.beta.-only domain described herein. For example, the TCRs may comprise, or consist essentially of single .alpha. TCR chain, a single .beta. TCR chain, a single .gamma. TCR chain, or a single .delta. TCR chain fused to one or more V.beta.-only domains.
[0290] The TCRs may engage antigens using complementarity determining regions (CDRs). Each TCR may contain three complement determining regions (CDR1, CDR2, and CDR3).
[0291] The first and/or second ligand binding V.beta.-only domain may be a human TCR variable domain. Alternatively, the first and/or second V.beta.-only domain may be a non-human TCR variable domain. The first and/or second V.beta.-only domain may be a mammalian TCR variable domain. The first and/or second V.beta.-only domain may be a vertebrate TCR variable domain.
[0292] Where V.beta.-only domain is incorporated into a fusion protein, for example a fusion protein comprising a TCR subunit, and optionally, an additional stimulatory intracellular domain, the fusion protein may comprise a V.beta.-only domain and any other protein domain or domains.
[0293] TCR receptors comprising transmembrane domains isolated or derived from any source are envisaged as within the scope of the fusion proteins of the disclosure.
[0294] The TCR transmembrane domain may be one that is associated with one of the other domains of the fusion protein, or isolated or derived from the same protein as one of the other domains of the fusion protein. The transmembrane domain and the second intracellular domain may be from the same protein, for example a TCR complex subunit such as TCR alpha, TCR beta, CD3 delta, CD3 epsilon or CD3 gamma. The extracellular domain (svd-TCR), the transmembrane domain and the second intracellular domain may be from the same protein, for example a TCR complex subunit such as TCR alpha, TCR beta, CD3 delta, CD3 epsilon or CD3 gamma.
[0295] The TCR extracellular domain (comprising one or more ligand binding domains, such as V.beta.-only domain and scFv domains), the transmembrane domain and the intracellular domain(s) may be from different proteins. For example, the engineered svd-TCR may comprise a CD28 transmembrane domain with a CD28, 4-1BB and CD3.zeta. intracellular domain.
[0296] The TCR transmembrane domain may be derived from a natural or recombinant source. When the source is natural, the domain may be derived from any membrane-bound or transmembrane protein.
[0297] The transmembrane domain may be capable of signaling to the intracellular domain(s) whenever the TCR complex is bound to a target. A transmembrane domain of particular use in this receptors of the disclosure may include at least the transmembrane region(s) of the alpha, beta, or zeta chain of the TCR, CD3 delta, CD3 epsilon or CD3 gamma, CD28, CD3 epsilon, CD45, CD4, CD5, CD8, CD9, CD16, CD22, CD33, CD37, CD64, CD80, CD86, CD134, CD137, CD154.
[0298] The transmembrane domain can be attached to the extracellular region of the fusion protein, e.g., the antigen binding domain of the TCR alpha or beta chain, via a hinge, e.g., a hinge from a human protein. For example, in one embodiment, the hinge can be a human immunoglobulin (Ig) hinge, e.g., an IgG4 hinge, or a CD8a hinge. The hinge may be isolated or derived from CD8.alpha. or CD28.
[0299] For example, an exemplary hinge isolated or derived from CD8a hinge comprises an amino acid sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 1 and/or encoded by a nucleotide sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 2.
[0300] An exemplary CD28 hinge may comprise an amino acid sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to SEQ ID NO: 3 and/or is encoded by a nucleotide sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 4.
[0301] The transmembrane domain may comprise a TCR alpha transmembrane domain, a TCR beta transmembrane domain, or a CD3 zeta transmembrane domain, such as those disclosed by the present Inventors in PCT International Application No. PCT/US2020/045250, which is incorporated by reference.
[0302] A transmembrane domain can include one or more additional amino acids adjacent to the transmembrane region, e.g., one or more amino acids associated with the extracellular region of the protein from which the transmembrane was derived (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or up to 15 amino acids of the extracellular region) and/or one or more additional amino acids associated with the intracellular region of the protein from which the transmembrane protein is derived (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or up to 15 amino acids of the intracellular region).
[0303] The transmembrane domain can be selected or modified by amino acid substitution to avoid binding of such domains to the transmembrane domains of the same or different surface membrane proteins, e.g., to minimize interactions with other members of the receptor complex or to minimize interactions with other receptors. This can help, for example, to ensure that the receptors remain at a sufficient distance apart on the surface of the immune cell to prevent blocking receptor inversion.
[0304] When present, the transmembrane domain may be a natural TCR transmembrane domain, a natural transmembrane domain from a heterologous membrane protein, or an artificial transmembrane domain. The transmembrane domain may be a membrane anchor domain.
[0305] Without limitation, a natural or artificial transmembrane domain may comprise a hydrophobic a helix of about 20 amino acids, often with positive charges flanking the transmembrane segment.
[0306] The transmembrane domain may have one transmembrane segment or more than one transmembrane segment. Prediction of transmembrane domains/segments may be made using publicly available prediction tools, e.g., TMHMM (Krogh et al., Journal of Molecular Biology 2001, 305(3):567-580) and TMpred (Hoppe-Seyler, Hofmann & Stoffel Biol. Chem. 1993; 347: 166), which are incorporated by reference. Non-limiting examples of membrane anchor systems include platelet derived growth factor receptor (PDGFR) transmembrane domain, glycosylphosphatidylinositol (GPI) anchor (added post-translationally to a signal sequence) and the like.
[0307] In certain aspects, transmembrane domain comprises a TCR alpha transmembrane domain. In some embodiments, the TCR alpha transmembrane domain comprises an amino acid sequence having at least 85% identity, at least 90% identity, at least 95% identity, at least 96% identity, at least 97% identity, at least 98% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 26 and/or is encoded by a nucleotide sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 27.
[0308] In some embodiments, the transmembrane domain comprises a TCR beta transmembrane domain. In some embodiments, the TCR beta transmembrane domain comprises an amino acid sequence having at least 85% identity, at least 90% identity, at least 95% identity, at least 96% identity, at least 97% identity, at least 98% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 28 or 35 and/or is encoded by a nucleotide sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 20 or 36.
[0309] In some embodiments, the transmembrane comprises a CD3 zeta transmembrane domain. In some embodiments, the CD3 zeta transmembrane domain comprises an amino acid sequence having at least 85% identity, at least 90% identity, at least 95% identity, at least 96% identity, at least 97% identity, at least 98% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 29.
[0310] In some embodiments, the CD3 zeta transmembrane domain comprises, or consists essentially of, SEQ ID NO: 29. The disclosure provides fusion proteins comprising an intracellular domain. An "intracellular domain," refers to an intracellular portion of a protein. The TCR intracellular domain may comprise one or more domains capable of providing a stimulatory signal to a transmembrane domain. The intracellular domain may comprise a first intracellular domain capable of providing a stimulatory signal and a second intracellular domain capable of providing a stimulatory signal. The intracellular domain may comprise a first, second and third intracellular domain capable of providing a stimulatory signal.
[0311] The intracellular domains capable of providing a stimulatory signal may be selected from the group consisting of a CD28 molecule (CD28) domain, a LCK proto-oncogene, Src family tyrosine kinase (Lck) domain, a TNF receptor superfamily member 9 (4-1BB) domain, a TNF receptor superfamily member 18 (GITR) domain, a CD4 molecule (CD4) domain, a CD8a molecule (CD8a) domain, a FYN proto-oncogene, Src family tyrosine kinase (Fyn) domain, a zeta chain of T cell receptor associated protein kinase 70 (ZAP70) domain, a linker for activation of T cells (LAT) domain, lymphocyte cytosolic protein 2 (SLP76) domain, (TCR) alpha, TCR beta, CD3 delta, CD3 gamma and CD3 epsilon intracellular domains.
[0312] The TCR intracellular domain may comprise at least one intracellular signaling domain. An intracellular signaling domain generates a signal that promotes a function a cell, for example an immune effector function of a TCR containing cell, e.g., a TCR-expressing T cell. In certain methods and cells of the disclosure, the intracellular domain of the fusion proteins includes at least one intracellular signaling domain. For example, the intracellular domains of CD3 gamma, delta or epsilon comprise signaling domains.
[0313] The extracellular domain, transmembrane domain and intracellular domain may be isolated or derived from the same protein, for example T cell receptor (TCR) alpha, TCR beta, CD3 delta, CD3 gamma or CD3 epsilon.
[0314] Examples of intracellular domains for use in fusion proteins of the disclosure include the cytoplasmic sequences of the TCR alpha, TCR beta, CD3 zeta, and 4-1BB, and the intracellular signaling co-receptors that act in concert to initiate signal transduction following antigen receptor engagement, as well as any derivative or variant of these sequences and any recombinant sequence that has the same functional capability.
[0315] The intracellular signaling domain may comprise a primary intracellular signaling domain. Exemplary primary intracellular signaling domains include those derived from the proteins responsible for primary stimulation, or antigen dependent stimulation.
[0316] In some embodiments, the stimulatory domain comprises a CD28 intracellular domain. In some embodiments, the CD28 intracellular domain comprises an amino acid sequence having at least 85% identity, at least 90% identity, at least 95% identity, at least 96% identity, at least 97% identity, at least 98% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 37 and/or is encoded by a nucleotide sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 30.
[0317] In some embodiments, the stimulatory domain comprises a 4-IBB intracellular domain. In some embodiments, the 4-IBB intracellular domain comprises an amino acid sequence having at least 85% identity, at least 90% identity, at least 95% identity, at least 96% identity, at least 97% identity, at least 98% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 39 and/or is encoded by a nucleotide sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 40.
[0318] An intracellular signaling domain is generally responsible for activation of at least one of the normal effector functions of the immune cell in which the fusion protein has been introduced. The term "effector function" refers to a specialized function of a cell. Effector function of a T cell, for example, may be cytolytic activity or helper activity including the secretion of cytokines.
[0319] Thus, "intracellular signaling domain" refers to the portion of a protein which transduces the effector function signal and directs the cell to perform a specialized function. While in some cases the entire intracellular signaling domain can be employed, in many cases it is not necessary to use the entire intracellular signaling domain. To the extent that a truncated portion of the intracellular signaling domain is used, such truncated portion may be used in place of the intact chain as long as it transduces the effector function signal. The term intracellular signaling domain is thus meant to include any truncated portion of the intracellular signaling domain sufficient to transduce the effector function signal.
[0320] The intracellular domain may comprise the entirety or a portion of a CD3 delta intracellular domain, a CD3 epsilon intracellular domain, a CD3 gamma intracellular domain, or a CD3 zeta intracellular domain, such as those disclosed by the present inventors in PCT International Application No. PCT/US2020/045250, which is incorporated by reference.
[0321] The intracellular domain may comprise a TCR alpha intracellular domain or a TCR beta intracellular domain, such as those disclosed by the present inventors in PCT International Application No. PCT/US2020/045250, incorporated by reference.
[0322] The intracellular signaling domain may comprise at least one stimulatory intracellular domain. The intracellular signaling domain may comprise a primary intracellular signaling domain, such as a CD3 delta, CD3 gamma and CD3 epsilon intracellular domain, and one additional stimulatory intracellular domain, for example a co-stimulatory domain. The intracellular signaling domain may comprise a primary intracellular signaling domain, such as a CD3 delta, CD3 gamma and CD3 epsilon intracellular domain, and two additional stimulatory intracellular domains.
[0323] An exemplary CD3 delta intracellular domain may comprise, for example, an amino acid sequence having at least 85% identity, at least 90% identity, at least 95% identity, at least 96% identity, at least 97% identity, at least 98% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 30 and/or is encoded by a nucleotide sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 31.
[0324] An exemplary CD3 epsilon intracellular domain may comprise, for example, an amino acid sequence having at least 85% identity, at least 90% identity, at least 95% identity, at least 96% identity, at least 97% identity, at least 98% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 32 and/or is encoded by a nucleotide sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 19.
[0325] An exemplary CD3 gamma intracellular domain may comprise, for example, an amino acid sequence having at least 85% identity, at least 90% identity, at least 95% identity, at least 96% identity, at least 97% identity, at least 98% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 22 and/or is encoded by a nucleotide sequence having at least 80% identity, at least 90% identity, at least 95% identity, at least 99% identity or is identical to a sequence of SEQ ID NO: 9.
[0326] Exemplary co-stimulatory intracellular signaling domains include those derived from proteins responsible for co-stimulatory signals, or antigen independent stimulation.
[0327] The term "co-stimulatory molecule" refers to the cognate binding partner on a T-cell that specifically binds with a co-stimulatory ligand, thereby mediating a co-stimulatory response by the T-cell, such as, but not limited to, proliferation. Co-stimulatory molecules are cell surface molecules other than antigen receptors. Co-stimulatory molecules and their ligands are required for an efficient immune response. Co-stimulatory molecules include, but are not limited to an MHC class I molecule, BTLA, a Toll ligand receptor, as well as DAP10, DAP12, CD30, LIGHT, OX40, CD2, CD27, CDS, ICAM-1, LFA-1 (CD11a/CD18) 4-1BB (CD137, TNF receptor superfamily member 9), and CD28 molecule (CD28).
[0328] A "co-stimulatory domain", sometimes referred to as "a co-stimulatory intracellular signaling domain" can be the intracellular portion of a co-stimulatory protein. A co-stimulatory domain can be a domain of a co-stimulatory protein that transduces the co-stimulatory signal. A co-stimulatory protein can be represented in the following protein families: TNF receptor proteins, Immunoglobulin-like proteins, cytokine receptors, integrins, signaling lymphocytic activation molecules (SLAM proteins), and activating NK cell receptors. Examples of such molecules include CD27, CD28, 4-1BB (CD137), OX40, GITR, CD30, CD40, ICOS, BAFFR, HVEM, lymphocyte function-associated antigen-1 (LFA-1), CD2, CD7, LIGHT, NKG2C, SLAMF7, NKp80, CD160, B7-H3, a ligand that specifically binds with CD83, CD4, and the like. The co-stimulatory domain can comprise the entire intracellular portion, or the entire native intracellular signaling domain, of the molecule from which it is derived, or a functional fragment thereof.
[0329] The stimulatory domain may comprise a co-stimulatory domain. The co-stimulatory domain may comprise a CD28 or 4-1BB co-stimulatory domain. CD28 and 4-1BB are well characterized co-stimulatory molecules required for full T cell activation and known to enhance T cell effector function. For example, CD28 and 4-1BB have been utilized in chimeric antigen receptors (CARs) to boost cytokine release, cytolytic function, and persistence over the first-generation CAR containing only the CD3 zeta signaling domain. Likewise, inclusion of co-stimulatory domains, for example CD28 and 4-1BB domains, in engineered TCR can increase T cell effector function and specifically allow co-stimulation in the absence of co-stimulatory ligand, which is typically down-regulated on the surface of tumor cells.
[0330] The stimulatory domain may comprise or be derived from a CD28 intracellular domain or a 4-1BB intracellular domain, such as those disclosed by the present inventors in PCT International Application No. PCT/US2020/045250, which is incorporated herein by reference.
[0331] The disclosure provides inhibitory intracellular domains which can be fused to the transmembrane or intracellular domain of any of the TCR subunits to generate a blocking TCR.
[0332] The inhibitory intracellular domain may comprise an immunoreceptor tyrosine-based inhibitory motif (ITIM). The inhibitory intracellular domain comprising an ITIM can be isolated or derived from an immune checkpoint inhibitor such as CTLA-4 and PD-1.
[0333] Inhibitory domains can be isolated from human tumor necrosis factor related apoptosis inducing ligand (TRAIL) receptor and CD200 receptor 1.
[0334] The inhibitory domain may comprise an intracellular domain, a transmembrane domain or a combination thereof. The inhibitory domain may comprise an intracellular domain, a transmembrane domain, a hinge region or a combination thereof. The inhibitory domain may comprise an immunoreceptor tyrosine-based inhibitory motif (ITIM). The inhibitory domain comprising an ITIM can be isolated or derived from an immune checkpoint inhibitor such as CTLA-4 and PD-1.
[0335] Inhibitory domains can be isolated from human tumor necrosis factor related apoptosis inducing ligand (TRAIL) receptor and CD200 receptor 1. The inhibitory domain can be isolated or derived from a human protein, for example a human TRAIL receptor, CTLA-4, or PD-1 protein. In some embodiments, the TRAIL receptor comprises TR10A, TR10B or TR10D.
[0336] Endogenous TRAIL is expressed as a 281-amino acid type II trans-membrane protein, which is anchored to the plasma membrane and presented on the cell surface. TRAIL is expressed by natural killer cells, which, following the establishment of cell-cell contacts, can induce TRAIL-dependent apoptosis in target cells. Physiologically, the TRAIL-signaling system was shown to be essential for immune surveillance, for shaping the immune system through regulating T-helper cell 1 versus T-helper cell 2 as well as "helpless" CD8+ T-cell numbers, and for the suppression of spontaneous tumor formation.
[0337] The inhibitory domain may comprise an intracellular domain isolated or derived from a CD200 receptor. The cell surface glycoprotein CD200 receptor 1 (Uniprot ref: Q8TD46) represents another example of an inhibitory intracellular domain of the present invention. This inhibitory receptor for the CD200/OX2 cell surface glycoprotein limits inflammation by inhibiting the expression of proinflammatory molecules including TNF-alpha, interferons, and inducible nitric oxide synthase (iNOS) in response to selected stimuli.
[0338] The inhibitory domain may be isolated or derived from killer cell immunoglobulin like receptor, three Ig domains and long cytoplasmic tail 2 (KIR3DL2), killer cell immunoglobulin like receptor, three Ig domains and long cytoplasmic tail 3 (KIR3DL3), leukocyte immunoglobulin like receptor B1 (LIR1), programmed cell death 1 (PD1), Fc gamma receptor IIB (FcgRIIB), killer cell lectin like receptor K1 (NKG2D), CTLA-4, a domain containing a synthetic consensus ITIM, a ZAP70 SH2 domain (e.g., one or both of the N and C terminal SH2 domains), or ZAP70 KI_K369A (kinase inactive ZAP70).
[0339] The inhibitory domain can be isolated or derived from a human protein.
[0340] The blocking receptor may comprise a cytoplasmic domain and transmembrane domain isolated or derived from the same protein, for example an ITIM containing protein. The blocking receptor may comprise a cytoplasmic domain, a transmembrane domain, and an extracellular domain or a portion thereof isolated or derived isolated or derived from the same protein, for example an ITIM containing protein. The blocking receptor may comprise a hinge region isolated or derived from isolated or derived from the same protein as the intracellular domain and/or transmembrane domain, for example an ITIM containing protein.
[0341] The blocking receptor may be a TCR comprising an inhibitory domain (an inhibitory TCR). The inhibitory TCR may comprise an inhibitory intracellular domain and/or an inhibitory transmembrane domain. The inhibitory intracellular domain can be fused to the intracellular domain of any one or more subunits of the TCR complex, including TCR alpha, TCR beta, CD3 delta, CD3 gamma or CD3 epsilon, or a portion of any thereof. The inhibitory intracellular domain can be fused to the transmembrane domain of TCR alpha, TCR beta, CD3 delta, CD3 gamma or CD3 epsilon.
[0342] The blocking receptor may comprise a hinge, transmembrane domain, and/or an intracellular domain derived from leukocyte immunoglobulin like receptor B1 (LILRBI). The blocking receptor may comprise the intracellular domain of the protein phosphoprotein membrane anchor with glycosphingolipid microdomains 1 (PAG1) or a functional variant thereof, and optionally hinge, a transmembrane domain, and/or one or more further intracellular domains. The transmembrane domain may be the transmembrane domain of PAG1. The hinge, transmembrane domain, and/or a further intracellular domain may be from leukocyte immunoglobulin like receptor B1 (LILRB1), PAG1 or a combination thereof. Examples of such blocking receptors have been disclosed by the Inventors of the present disclosure in U.S. Provisional Application Nos. 63/018,881 and 62/946,888 and PCT/US2021/030149, which are herein incorporated by reference in its entirety.
[0343] In some embodiments of the receptors having one or more domains isolated or derived from LILRB1, the one or more domains of LILRB1 comprise an amino acid sequence that is at least 80%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99% or is identical to a sequence or subsequence of SEQ ID NO: 65, 77, 78, 79, 80, 81, 82, 83, 84, or 85 and/or is encoded by a polynucleotide sequence that is at least 80%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99% or is identical to a sequence or subsequence of SEQ ID NO: 66.
[0344] In various embodiments, an blocking receptor is provided, comprising a polypeptide, wherein the polypeptide comprises one or more of: an LILRB1 hinge domain or functional fragment or variant thereof; an LILRB1 transmembrane domain or a functional variant thereof; and an LILRB1 intracellular domain or an intracellular domain comprising at least one, or at least two immunoreceptor tyrosine-based inhibitory motifs (ITIMs), wherein each ITIM is independently selected from and/or includes a sequence of SEQ ID NOS: 67, 68, 69, 70, 71, 72, 73, 74, 75, or 76.
[0345] Assays
[0346] Provided herein are assays that can be used to measure the activity of the engineered receptors and immune cells disclosed herein.
[0347] Receptor activity may be assayed using a cell line engineered to express a reporter of receptor activity such as a luciferase reporter. Exemplary cell lines include Jurkat T cells, although any suitable cell line known in the art may be used. For example, Jurkat cells expressing a luciferase reporter under the control of an NFAT promoter can be used as effector cells. Expression of luciferase by this cell line reflects TCR-mediated signaling.
[0348] Nuclear factor of activated T cells (NFAT) is a family of transcription factors shown to be important in immune response. The NFAT transcription factor family consists of five members NFATc1, NFATc2, NFATc3, NFATc4, and NFAT5. NFAT plays a role in regulating inflammation. As used herein, an NFAT promoter is a promoter that is regulated (i.e., activated or repressed) when NFAT is expressed in a cell. NFAT target promoters are described in Badran, B. M. et al., (2002) J. Biological Chemistry, Vol. 277: 47136-47148, incorporated herein by reference, and contain NFAT consensus sequences such as GGAAA.
[0349] The reporter cells can be transfected with each of the various fusion protein constructs, combinations of fusion protein constructs or controls described herein. Expression of the fusion proteins in reporter cells can be confirmed by using fluorescently labeled MHC tetramers, for example Alexa Fluor 647-labeled NY-ESO-1-MHC tetramer, to detect expression of the fusion protein.
[0350] To assay the activity of engineered receptors, target cells can be loaded with activating or blocking ligands prior to exposure to the cells comprising the reporter and the engineered receptor(s). For example, target cells can be loaded with ligands at least 12, 14, 16, 18, 20, 22 or 24 hours prior to exposure to immune cells. Exemplary target cells include A375 cells, although any suitable cells known in the art may be used. In some cases, target cells can be loaded with serially diluted concentrations of a ligand, such as NY-ESO-1 peptide. The immune cells can then be cocultured with target cells for a suitable period of time, for example 6 hours. Luciferase is then measured by luminescence reading after co-culture. Luciferase luminescence can be normalized to maximum and minimum intensity to allow comparison of activating peptide concentrations for each engineered receptor construct.
[0351] Provided herein are methods of determining the relative EC.sub.50 of engineered receptors of the disclosure. As used herein, "EC.sub.50" refers to the concentration of an inhibitor or agent to cause half the maximal response (or binding). Binding of the ligand, or probe to the engineered receptor can be measured by staining with labeled peptide or labeled peptide-MHC complex, for example MHC:NY-ESO-1 pMHC complex conjugated with fluorophore. EC.sub.50 can be obtained by nonlinear regression curve fitting of reporter signal with peptide titration. Probe binding and EC.sub.50 can be normalized to the levels of benchmark TCR without a fusion protein, e.g. NY-ESO-1 (clone 1G4).
[0352] Methods of assessing the effects of receptor activation on gene expression are known in the art, and include the use of reporter genes, whose expression can be quantified. Reporter genes can be used for identifying potentially transfected or transduced cells and for evaluating the functionality of regulatory sequences.
[0353] In general, a reporter gene is a gene that is not present in or expressed by the recipient organism or tissue and that encodes a polypeptide whose expression is manifested by some easily detectable property, e.g., enzymatic activity. Expression of the reporter gene is assayed at a suitable time after the DNA has been introduced into the recipient cells. Suitable reporter genes may include genes encoding luciferase, beta-galactosidase, chloramphenicol acetyl transferase, secreted alkaline phosphatase, or the green fluorescent protein gene. See, e.g., Ui-Tei et al., 2000 FEBS Letters 479: 79-82, which is incorporated herein by reference.
[0354] Suitable expression systems are well known and may be prepared using known techniques or obtained commercially. In general, the construct with the minimal 5' flanking region showing the highest level of expression of reporter gene is identified as the promoter. Such promoter regions may be linked to a reporter gene and used to evaluate agents for the ability to modulate promoter-driven transcription. In exemplary embodiments, an NFAT promoter operably linked to a reporter gene is used to evaluate the expression of the receptors of the disclosure on NFAT signaling.
[0355] Exemplary assays have been disclosed by the present Inventors in PCT International Application Nos. PCT/US2019/037038, PCT/US2020/045250, PCT/US2020/045228, PCT/US2020/045373, and PCT/CA2016/051421, and U.S. Provisional Application Nos. 62/946,888, 62/934,419, 63/076,123, 63/068,244, 63/068,249, 63/068,245, 63/068,246, 63/065,324, and 63/037,975, which are each incorporated herein by reference.
[0356] Immune Cells
[0357] An immune cell can be a cell involved in the innate or adaptive (acquired) immune systems. Exemplary innate immune cells include phagocytic cells such as neutrophils, monocytes and macrophages, Natural Killer (NK) cells, polymophonuclear leukocytes such as neutrophils eosinophils and basophils and mononuclear cells such as monocytes, macrophages and mast cells. Immune cells with roles in acquired immunity include lymphocytes such as T-cells and B-cells. An engineered immune cell of the present disclosure can be derived from an innate immune cell and/or can be a modified innate immune cell.
[0358] A T cell is a type of lymphocyte that originates from a bone marrow precursor that develops in the thymus gland. There are several distinct types of T-cells which develop upon migration to the thymus, which include, helper CD4+ T-cells, cytotoxic CD8+ T cells, memory T cells, regulatory CD4+ T-cells and stem memory T-cells. Different types of T cells can be distinguished by the ordinarily skilled artisan based on their expression of markers. Methods of distinguishing between T cell types will be readily apparent to the ordinarily skilled artisan.
[0359] The present disclosure also comprises methods of producing and modifying the engineered immune cells disclosed herein. The engineered immune cells of the present disclosure can be derived from any naturally occurring immune cell.
[0360] Methods of producing the disclosed immune cells may comprise introducing polynucleotide encoding the activating and blocking receptors into cells, optionally using vectors. The resulting cells express the polynucleotide encoding the receptors.
[0361] Methods transforming populations of immune cells, such as T cells, with vectors will be readily apparent to the person of ordinary skill in the art. For example, CD3+ T cells can be isolated from PBMCs using a CD3+ T cell negative isolation kit (Miltenyi), according to manufacturer's instructions. T cells can be cultured at a density of 1.times.10{circumflex over ( )}6 cells/mL in X-Vivo 15 media supplemented with 5% human AB serum and 1% Pen/strep in the presence of CD3/28 Dynabeads (1:1 cell to bead ratio) and 300 Units/mL of IL-2 (Miltenyi). After 2 days, T cells can be transduced with viral vectors, such as lentiviral vectors using methods known in the art. In some embodiments, the viral vector is transduced at a multiplicity of infection (MOI) of 5. Cells can then be cultured in IL-2 or other cytokines such as combinations of IL-7/15/21 for an additional 5 days prior to enrichment.
[0362] Methods of isolating and culturing other populations of immune cells, such as B cells, or other populations of T cells, will be readily apparent to the person of ordinary skill in the art. Although this method outlines a potential approach it should be noted that these methodologies are rapidly evolving. For example, high levels of viral transduction of peripheral blood mononuclear cells can be achieved after 5 days of growth to generate a >99% CD3+ highly transduced cell population.
[0363] In some embodiments, the first and second receptors are encoded by a single vector. Methods of encoding multiple polypeptides using a single vector will be known to persons of ordinary skill in the art, and include, inter alia, encoding multiple polypeptides under control of different promoters, or, if a single promoter is used to control transcription of multiple polypeptides, use of sequences encoding internal ribosome entry sites (IRES) and/or self-cleaving peptides. Exemplary self-cleaving peptides include T2A, P2A, E2A and F2A self-cleaving peptides. In some embodiments, the T2A self-cleaving peptide comprises a sequence of EGRGSLLTCGDVEENPGP (SEQ ID NO: 271). In some embodiments, the P2A self-cleaving peptide comprises a sequence of ATNFSLLKQAGDVEENPGP (SEQ ID NO: 192). In some embodiments, the E2A self-cleaving peptide comprises a sequence of QCTNYALLKLAGDVESNPGP (SEQ ID NO: 272). In some embodiments, the F2A selfcleaving peptide comprises a sequence of VKQTLNFDLLKLAGDVESNPGP (SEQ ID NO: 273).
[0364] Methods of activating and culturing populations immune cells comprising the receptors, polynucleotides, or vectors of the disclosure will be readily apparent to the person of ordinary skill in the art.
[0365] Whether prior to or after genetic modification, the immune cells of the present disclosure can be activated and expanded generally using methods as described, for example, in U.S. Pat. Nos. 6,352,694; 6,534,055; 6,905,680; 6,692,964; 5,858,358; 6,887,466; 6,905,681; 7,144,575; 7,067,318; 7,172,869; 7,232,566; 7,175,843; 5,883,223; 6,905,874; 6,797,514; 6,867,041, 10,040,846; and U.S. Pat. Appl. Pub. No. 2006/0121005, each of which are incorporated herein by reference.
[0366] Immune cells of the instant disclosure can be expanded and activated in vitro. Generally, the immune cells of the instant disclosure are expanded in vitro by contact with a surface having an attached agent that stimulates a CD3/TCR complex associated signal and a ligand that stimulates a co-stimulatory molecule on the surface of the immune cells. Immune cell populations may be stimulated as described herein, such as by contact with an anti-CD3 antibody. For co-stimulation of an accessory molecule on the surface of the immune cells, a ligand that binds the accessory molecule can be used. For example, a population of T cells can be contacted with an anti-CD3 antibody and an anti-CD28 antibody, under conditions appropriate to stimulate proliferation of the T cells. In order to stimulate proliferation of either CD4+ T cells or CD8+ T cells, an anti-CD3 antibody and an anti-CD28 antibody can be used. Examples of an anti-CD28 antibody include 9.3, B-T3, XR-CD28 (Diaclone, Besancon, France) can be used as can other methods commonly known in the art, such as in Berg et al., Transplant Proc. 30(8):3975-3977, 1998; Haanen et al., J. Exp. Med. 190(9):13191328, 1999; and Garland et al., J. Immunol Meth. 227(1-2):53-63, 1999, each of which is incorporated herein by reference.
[0367] The primary stimulatory signal and the co-stimulatory signal for an immune cell of the disclosure may be provided by different protocols. For example, the agents providing each signal may be in solution or coupled to a surface. When coupled to a surface, the agents may be coupled to the same surface (i.e., in "cis" formation) or to separate surfaces (i.e., in "trans" formation). Alternatively, one agent may be coupled to a surface and the other agent in solution. The agent providing the co-stimulatory signal may be bound to a cell surface and the agent providing the primary activation signal is in solution or coupled to a surface. Both agents can be in solution. The agents may be in soluble form, and then cross-linked to a surface, such as a cell expressing Fc receptors or an antibody or other binding agent which will bind to the agents. U.S. Patent Application Publication Nos. 2004/0101519 and 2006/0034810, which are incorporated herein by reference, disclose artificial antigen presenting cells (aAPCs) that are contemplated for use in activating and expanding immune cells of the present invention.
[0368] The two agents may be immobilized on beads, either on the same bead, i.e., "cis," or to separate beads, i.e., "trans." By way of example, the agent providing the primary activation signal is an anti-CD3 antibody or an antigen-binding fragment thereof and the agent providing the co-stimulatory signal is an anti-CD28 antibody or antigen-binding fragment thereof; and both agents are co-immobilized to the same bead in equivalent molecular amounts.
[0369] In certain methods of the disclosure, a 1:1 ratio of each antibody bound to the beads for CD4+ immune cell expansion and growth is used. The ratio of CD3:CD28 antibody bound to the beads may range from 100:1 to 1:100, and all integer values there between. In one aspect of the present disclosure, more anti-CD28 antibody is bound to the particles than anti-CD3 antibody, i.e., the ratio of CD3:CD28 is less than one. In certain methods of the disclosure, the ratio of anti CD28 antibody to anti CD3 antibody bound to the beads is greater than 2:1.
[0370] Ratios of particles to cells from 1:500 to 500:1, and any integer values in between, may be used to stimulate immune cells, such as T cells, or other target cells. As those of ordinary skill in the art can readily appreciate, the ratio of particles to cells may depend on particle size relative to the target cell. For example, small sized beads may only bind a few cells, while larger beads can bind many.
[0371] In certain methods of the disclosure, the ratio of cells to particles ranges from 1:100 to 100:1, and any integer values in-between, can be used to stimulate the immune cells. In certain methods of the disclosure, the ratio comprises 1:9 to 9:1 and any integer values in between. In certain methods, a ratio of 1:1 cells to beads may be used. One of skill in the art will appreciate that a variety of other ratios may be suitable for use in the present invention. In particular, the ratios used will vary depending on particle size and on cell size and type.
[0372] In further methods of the present disclosure, the immune cells, such as T cells, are combined with agent-coated beads, the beads and the cells are subsequently separated, and then the cells are cultured. Alternatively, prior to culture, the agent-coated beads and cells are not separated, but are cultured together. The beads and cells may initially be concentrated by application of a force, such as a magnetic force, resulting in increased ligation of cell surface markers, thereby inducing cell stimulation.
[0373] By way of example, cell surface proteins may be ligated by allowing paramagnetic beads to which anti-CD3 and anti-CD28 are attached to contact the immune cells. The cells (for example, CD4+ T cells) and beads (for example, DYNABEADS CD3/CD28 T paramagnetic beads at a ratio of 1:1) are combined in a buffer. Again, those of ordinary skill in the art can readily appreciate any cell concentration may be used. In certain methods, it may be desirable to significantly decrease the volume in which particles and cells are mixed together (i.e., increase the concentration of cells), to ensure maximum contact of cells and particles. For example, a concentration of about 2 billion cells/ml can be used. Alternatively, greater than 100 million cells/ml can be used. A concentration of cells of 10, 15, 20, 25, 30, 35, 40, 45, or 50 million cells/ml can be used. A concentration of cells from 75, 80, 85, 90, 95, or 100 million cells/ml can be used. Concentrations of 125 or 150 million cells/ml can be used. In certain methods, cells are cultured at a density of 1.times.10.sup.6 cells/mL.
[0374] The mixture may be cultured for several hours (about 3 hours) to about 14 days or any hourly integer value in between. The beads and immune cells may be cultured together for 2-3 days. Conditions appropriate for immune cell culture include an appropriate media (e.g., Minimal Essential Media or RPMI Media 1640 or, X-vivo 15, (Lonza)) that may contain factors necessary for proliferation and viability, including serum (e.g., fetal bovine or human serum), interleukin-2 (IL-2), insulin, IFN-.gamma., IL-4, IL-7, GM-CSF, IL-10, IL-12, IL-15, TGF.beta., and TNF-.alpha. or any other additives for the growth of cells known to the skilled artisan. Other additives for the growth of cells include, but are not limited to, surfactant, plasmanate, and reducing agents such as N-acetyl-cysteine and 2-mercaptoethanol. Media can include RPMI 1640, AIM-V, DMEM, MEM, .alpha.-MEM, F-12, X-Vivo 15, and X-Vivo 20, Optimizer, with added amino acids, sodium pyruvate, and vitamins, either serum-free or supplemented with an appropriate amount of serum (or plasma) or a defined set of hormones, and/or an amount of cytokine(s) sufficient for the growth and expansion of immune cells. The media may comprise XVIVO-15 media supplemented with 5% human AB serum, 1% penicillin/streptomycin (pen/strep) and 300 Units/ml of IL-2 (Miltenyi).
[0375] The engineered immune cells can be maintained under conditions necessary to support growth, for example, an appropriate temperature (e.g., 37.degree. C.) and atmosphere (e.g., air plus 5% CO2).
[0376] Immune cells comprising receptors of the present disclosure may be autologous. Prior to expansion and genetic modification, a source of immune cells can obtained from a subject, such as a human patient. Immune cells, such as T cells, can be obtained from a number of sources, including peripheral blood mononuclear cells, bone marrow, lymph node tissue, cord blood, thymus tissue, tissue from a site of infection, ascites, pleural effusion, spleen tissue, and tumors.
[0377] In certain methods of the disclosure, any number of immune cell lines available in the art, may be used. Immune cells can be obtained from a unit of blood collected from a subject using any number of techniques known to the skilled artisan, such as Ficoll.TM. separation.
[0378] Cells from the circulating blood of an individual can be obtained by apheresis. The apheresis product typically contains lymphocytes, including T cells, monocytes, granulocytes, B cells, other nucleated white blood cells, red blood cells, and platelets. Cells collected by apheresis may be washed to remove the plasma fraction and to place the cells in an appropriate buffer or media for subsequent processing steps. The cells can be washed with phosphate buffered saline (PBS). The wash solution may lack calcium and magnesium or may lack many, if not all, divalent cations. As those of ordinary skill in the art would readily appreciate a washing step may be accomplished by methods known to those in the art, such as by using a semi-automated "flow-through" centrifuge (for example, the Cobe 2991 cell processor, the Baxter CytoMate, or the Haemonetics Cell Saver 5) according to the manufacturer's instructions. After washing, the cells may be resuspended in a variety of biocompatible buffers, such as, for example, Ca2+-free, Mg2+-free PBS, PlasmaLyte A, or other saline solution with or without buffer. Alternatively, the undesirable components of the apheresis sample may be removed and the cells directly resuspended in culture media.
[0379] Immune cells, such as T cells, can be isolated from peripheral blood lymphocytes by lysing the red blood cells and depleting the monocytes, for example, by centrifugation through a PERCOLL.TM. gradient or by counterflow centrifugal elutriation. Specific subpopulations of immune cells, such as T cells, B cells, or CD4+ T cells can be further isolated by positive or negative selection techniques. For example, T cells can be isolated by incubation with anti-CD4-conjugated beads, for a time period sufficient for positive selection of the desired T cells.
[0380] Enrichment of an immune cell population, such as a T cell population, by negative selection can be accomplished with a combination of antibodies directed to surface markers unique to the negatively selected cells. One method is cell sorting and/or selection via negative magnetic immune-adherence or flow cytometry that uses a cocktail of monoclonal antibodies directed to cell surface markers present on the cells negatively selected. For example, to enrich for CD4+ cells by negative selection, a monoclonal antibody cocktail typically includes antibodies to CD14, CD20, CD11b, CD16, HLA-DR, and CD8.
[0381] For isolation of a desired population of immune cells by positive or negative selection, the concentration of cells and surface (e.g., particles such as beads) can be varied. In certain embodiments, it may be desirable to significantly decrease the volume in which beads and cells are mixed together (i.e., increase the concentration of cells), to ensure maximum contact of cells and beads.
[0382] The cells may be incubated on a rotator for varying lengths of time at varying speeds at either 2-10.degree. C. or at room temperature.
[0383] T cells for stimulation, or PBMCs from which immune cells such as T cells are isolated, can also be frozen after a washing step. Wishing not to be bound by theory, the freeze and subsequent thaw step provides a more uniform product by removing granulocytes and to some extent monocytes in the cell population. After the washing step that removes plasma and platelets, the cells may be suspended in a freezing solution. While many freezing solutions and parameters are known in the art and will be useful in this context, one method involves using PBS containing 20% DMSO and 8% human serum albumin, or culture media containing 10% Dextran 40 and 5% Dextrose, 20% Human Serum Albumin and 7.5% DMSO, or 31.25% Plasmalyte-A, 31.25% Dextrose 5%, 0.45% NaCl, 10% Dextran 40 and 5% Dextrose, 20% Human Serum Albumin, and 7.5% DMSO or other suitable cell freezing media containing for example, Hespan and PlasmaLyte A, the cells then are frozen to -80.degree. C. at a rate of 1.degree. per minute and stored in the vapor phase of a liquid nitrogen storage tank. Other methods of controlled freezing may be used as well as uncontrolled freezing immediately at -20.degree. C. or in liquid nitrogen.
[0384] Exemplary immune cells and methods for producing the same include those that have been disclosed by the present Inventors in PCT International Application Nos. PCT/US2019/037038, PCT/US2020/045250, PCT/US2020/045228, PCT/US2020/045373, and PCT/CA2016/051421, and U.S. Provisional Application Nos. 62/946,888, 62/934,419, 63/076,123, 63/068,244, 63/068,249, 63/068,245, 63/068,246, 63/065,324, and 63/037,975, which are each incorporated herein by reference.
[0385] Target Ligands
[0386] The disclosure provides receptors comprising extracellular ligand binding domains. The ligand may be an antigen and the ligand binding domain may be an antigen binding domain.
[0387] Any suitable ligand binding domain is envisaged as within the scope of the receptors described herein.
[0388] The ligand binding domain of the activating or blocking receptors may comprise an antigen binding domain comprises an antibody fragment, a VP only domain, a linear antibody, a single-chain variable fragment (scFv), or a single domain antibody (sdAb).
[0389] The receptors may each comprise two polypeptides each having a part of a ligand-binding domain (e.g. cognates of a heterodimeric LDB, such as a TCR.alpha./.beta.- or Fab-based LBD). The disclosure further provides receptors having two polypeptides, each having a part of a ligand-binding domain (e.g. cognates of a heterodimeric LDB, such as a TCR.alpha./.beta.- or Fab-based LBD) and one part of the ligand binding domain is fused to a hinge or transmembrane domain, while the other part of the ligand binding domain has no intracellular domain. Further variations include receptors where each polypeptide has a hinge domain, and where each polypeptide has a hinge and transmembrane domain. Some receptors may not have a hinge domain.
[0390] The ligand binding domain of the receptors may comprise a Fab fragment of an antibody.
[0391] Receptors of the present disclosure may comprise a first polypeptide that comprises an antigen-binding fragment of the heavy chain of an antibody and an intracellular domain, and a second polypeptide of the receptor comprises an antigen-binding fragment of the light chain of the antibody. Alternatively, the first polypeptide may comprise an antigen-binding fragment of the light chain of the antibody and the intracellular domain, and the second polypeptide comprises an antigen-binding fragment of the heavy chain of the antibody.
[0392] The blocking and/or activating receptors may comprise an extracellular fragment of a T cell receptor (TCR).
[0393] Any macromolecule, including virtually all proteins or peptides, can serve as an antigen for the receptors described herein. Antigens can be derived from recombinant or genomic DNA. Any DNA, which comprises a nucleotide sequence or a partial nucleotide sequence encoding a protein that elicits an immune response, encodes an antigen. An antigen need not be encoded solely by a full-length nucleotide sequence of a gene. An antigen need not be encoded by a gene. An antigen can be generated synthesized or can be derived from a biological sample, or might be macromolecule besides a polypeptide. Such a biological sample can include, but is not limited to a tissue sample, a tumor sample, a cell or a fluid with other biological components.
[0394] In the engineered receptors of the present disclosure, the antigen-binding domain may specifically bind to a target selected from etiolate receptor, av.beta..beta. integrin, BCMA, B7-H3, B7-H6, CAIX, CD19, CD20, CD22, CD30, CD33, CD37, CD44, CD44v6, CD44v7/8, CD70, CD123, CD138, CD171, CEA, DLL4, EGP-2, EGP-40, CSPG4, EGFR, ErbB2 (HER2), ErbB3 (Her3), ErbB4 (Her4), EGFRvIII, EPCAM, EphA2, EpCAM, FAP, FBP, fetal acetylcholine receptor, Fzd7, GD2, GD3, Glypican-3 (GPC3), h5T4, IL-11R, IL13R-a2, KDR, .kappa. light chain, .lamda., light chain, LeY, LI CAM, MAGE-A1, mesothelin, MHC presented peptides, MUC1, MUC16, NCAM, NKG2D ligands, Notch1, Notch2/3, NYESO-1, PRAME, PSCA, PSMA, Survivin, TAG-72, TEMs, TERT, VEGFR2, and ROR1.
[0395] The antigen-binding domain may specifically bind peptide MHC (pMHC) as the antigen. Exemplary pMHC antigens include, but are not limited to, MAGE-A3 pMHC (e.g., FLWGPRALV and MPKVAELVHFL peptides), HPV E6 pMHC (e.g., TIHDIILECV peptide), HPV E7 pMHC (e.g., YMLDLQPET peptide) and NY-ESO-1 pMHC (e.g., LLEFYLAMPFA or SLLMWITQV peptides).
[0396] The antigen-binding domain may specifically bind to a target selected from CD33, CD38, a human leukocyte antigen (HLA), an organ specific antigen, a blood-brain barrier specific antigen, an Epithelial-mesenchymal transition (EMT) antigen, E-cadherin, cytokeratin, Opioid-binding protein/cell adhesion molecule (OPCML), HYLA2, Deleted in Colorectal Carcinoma (DCC), Scaffold/Matrix attachment region-binding protein 1 (SMAR1), cell surface carbohydrate and mucin type 0-glycan.
[0397] The antigen-binding domain of the blocking receptor may specifically bind to an antigen from a gene with high, homogeneous surface expression across tissues. High, homogeneous surface expression across tissues allows the blocking receptor to deliver a large, even inhibitory signal. The antigen may be encoded by a gene that is absent or polymorphic in in many tumors.
[0398] Methods of distinguishing the differential expression of blocking ligands (e.g., antigens) between target and non-target cells can be used in methods and systems of the invention. For example, the presence or absence of blocking ligands in nontarget and target cells can be assayed by immunohistochemistry with an antibody that binds to the inhibitor ligand, followed by microscopy or FACS, RNA expression profiling of target cells and non-target cells, or DNA sequencing of non-target and target cells to determine if the genomic locus of the blocking ligand comprises mutations in either the target or non-target cells.
[0399] Homozygous deletions in primary tumors are rare and small, and therefore unlikely to yield blocking ligand candidates. For example, in an analysis of 2218 primary tumors across 21 human cancer types, the top 4 candidates were CDKN2A, RB1, PTEN and N3PB2. However, CDKN2A (P16) was deleted in only 5% homozygous deletion across all cancers. Homozygous HLA-A deletions were found in less than 0.2% of cancers in Cheng et al., Nature Comm. 8:1221 (2017), incorporated herein by reference. In contrast, deletion of a single copy of gene in cancer cells due to loss of hemizygosity occurs far more frequently.
[0400] Thus, the blocking ligand may comprise an allele of a gene that is lost in target cells due to loss of heterozygosity, and the target cells may comprise cancer cells. Cancer cells undergo frequent genome rearrangements, including duplication and deletions. These deletions can lead to the deletion of one copy of one or more genes in the cancer cells.
[0401] Loss of heterozygosity (LOH) refers to a genetic change, whereby one of the two alleles in the genome of a cell or cells is deleted, leaving a single mono-allelic (hemizygous) locus.
[0402] The blocking ligand may comprise an HLA class I allele. The major histocompatibility complex (MHC) class I is a gene complex that encodes proteins that display antigens to cells of the immune system, triggering immune response. The Human Leukocyte Antigens (HLAs) corresponding to MHC class I are HLA-A, HLA-B and HLA-C.
[0403] The blocking ligand may comprise an HLA class I allele. The blocking ligand may comprise an allele of HLA class I that is lost in a target cell through LOH. HLA-A is a group of human leukocyte antigens (HLA) of the major histocompatibility complex (MHC) that are encoded by the HLA-A locus. HLA-A is one of three major types of human MHC class I cell surface receptors. The receptor is a heterodimer comprising a heavy .alpha. chain and smaller .beta. chain. The .alpha. chain is encoded by a variant of HLA-A, while the .beta. chain (.beta.2-microglobulin) is an invariant. There are several thousand variant HLA-A alleles, all of which fall within the scope of the instant disclosure.
[0404] The blocking ligand may comprise an HLA-B allele. The HLA-B gene has many possible variations (alleles). Hundreds of versions (alleles) of the HLA-B gene are known, each of which is given a particular number (such as HLAB27).
[0405] The blocking ligand may comprise an HLA-C allele. HLA-C belongs to the HLA class I heavy chain paralogues. This class I molecule is a heterodimer consisting of a heavy chain and a light chain (beta-2 microglobulin). Over one hundred HLA-C alleles have been described.
[0406] The HLA class I allele may have broad or ubiquitous RNA expression. The HLA class I allele may have a known, or generally high minor allele frequency. The HLA class I allele may not require a peptide-MHC antigen, for example when the HLA class I allele is recognized by a pan-HLA ligand binding domain.
[0407] The blocking ligand may comprise an HLA-A allele. The HLA-A allele may comprise HLA-A*02. Various single variable domains known in the art or disclosed herein that bind to and recognize HLA-A*02 are suitable for use in the present disclosure. Such scFvs include, for example and without limitation the following mouse and humanized scFv antibodies that bind HLA-A*02 in a peptide independent manner.
[0408] The blocking ligand (e.g., an antigen) may comprise a minor histocompatibility antigen (MiHA). The inhibitor ligand may comprise an allele of a MiHA that is lost in a target cell through LOH.
[0409] MiHAs are peptides derived from proteins that contain nonsynonymous differences between alleles and are displayed by common HLA alleles. The nonsynonymous differences can arise from SNPs, deletions, frameshift mutations or insertions in the coding sequence of the gene encoding the MiHA. Exemplary MiHAs can be about 9-12 amino acids in length and can bind to WIC class I and/or WIC class II proteins. Binding of the TCR to the MHC complex displaying the MiHA can activate T cells. The genetic and immunological properties of MiHAs will be known to the person of ordinary skill in the art. Candidate MiHAs are known peptides presented by known HLA class I alleles, are known to elicit T cell responses in the clinic (for example, in graft versus host disease, or transplant rejection), and allow for patient selection by simple SNP genotyping.
[0410] The MiHA may have broad or ubiquitous RNA expression. The MiHA may have high minor allele frequency. The MiHA may comprise a peptide derived from a Y chromosome gene.
[0411] The blocking ligand may comprise a Y chromosome gene, i.e. peptide encoded by a gene on the Y chromosome. The blocking ligand may comprise a peptide encoded by a Y chromosome gene that is lost in target cells through loss of Y chromosome (LoY). For example, about a third of the characterized MiHAs come from the Y chromosome. The Y chromosome contains over 200 protein coding genes, all of which are envisaged as within the scope of the instant disclosure.
[0412] As used herein, "loss of Y", or "LoY" refers a genetic change that occurs at high frequency in tumors whereby part or all of the Y chromosome is deleted, leading to a loss of Y chromosome encoded gene(s).
[0413] Loss of Y chromosome is known to occur in certain cancers. For example, there is a reported 40% somatic loss of Y chromosome in renal clear cell cancers (Arseneault et al., Sci. Rep. 7: 44876 (2017)). Similarly, clonal loss of the Y chromosome was reported in 5 out of 31 in male breast cancer subjects in Wong et al., Oncotarget 6(42):44927-40 (2015), incorporated herein by reference. Loss of the Y chromosome in tumors from male patients has been described as a "consistent feature" of head and neck cancer patients, as in el-Naggar et al., Am J Clin Pathol 105(1):102-8 (1996), incorporated herein by reference. Further, Y chromosome loss was associated with X chromosome disomy in four of seven male patients with gastric cancer in Saal et al., Virchows Arch B Cell Pathol (1993), incorporated herein by reference. Thus, Y chromosome genes can be lost in a variety of cancers, and can be used as blocking ligands with the engineered receptors of the instant disclosure targeting cancer cells.
[0414] The activating ligand may be a transferrin receptor (TFRC). Human transferrin receptor is described in NCBI record No. AAA61153.1, the contents of which are incorporated herein by reference.
[0415] The activating ligand may be a tumor specific antigen (TSA). The tumor specific antigen may be mesothelin (MSLN), CEACAM5 or EGFR. The TSA may be MSLN, CEA, EGFR, DLL4, CA125, GD2, ROR1 or HER2/NEU. The activating ligand may be a pan-HLA ligand, and the activating receptor ligand binding domain is a pan-HLA binding domain, i.e. a binding domain that binds to and recognizes an antigenic determinant shared among HLA I products, such as the HLA A, B and C loci. The activating ligand may also be another class I gene product; e.g., antigens encoded by HLA-E or F. Various single variable domains known in the art are suitable for use in embodiments. Such scFvs include, for example and without limitation the following mouse and humanized pan-HLA scFv antibodies. An exemplary pan-HLA ligand is W6/32, which recognizes a conformational epitope, reacting with HLA class I alpha3 and alpha2 domains. Further exemplary antibodies with broad HLA binding are known in the art and include HC-10 and TFL-006. Exemplary activating ligands and activating receptor ligand binding domains have been disclosed by the Inventors of the present disclosure in U.S. Provisional Application No. 63/018,881, which is herein incorporated by reference in its entirety.

EXAMPLES
Example 1
[0458] FIG. 4 provides experimental results showing that, for the engineered immune cells of the present disclosure expressing activating and blocking receptors, surface levels of the activating receptor decrease when the immune cells are in the presence of non-target cells expressing both the activating and blocking ligand.
[0459] FIGS. 5-7 provides experimental results showing that this reduced surface expression of the activating receptors corresponds with the ability of the immune cells to kill other cells. Thus, advantageously, when the immune cells are in limited or no contact with target cells, their ability to kill is diminished, thereby reducing non-target effects.
Example 2
[0460] Another surprising facet of the immune cells of the present invention is that the reduced surface expression of the activating receptors only occurs when the immune cells contact non-target cells expressing both the activating and blocking ligands. This is shown in FIG. 7.
Example 3
[0461] FIGS. 8-16 provide an experimental protocol and results that indicate the reduced expression of activating receptors is reversible upon contact with target cells.
Example 4
[0462] FIGS. 17-19 provide experimental results showing that, unlike the activating receptor, the blocking receptor does not undergo reduced surface expression in an appreciable amount in the presence of non-target cells.
Example 5
[0463] FIG. 22 shows experimental results indicating that the blocking receptor provides a blocking signal that dominates and inhibits the activating signal from the activating receptor.
[0464] Jurkat cells were transfected with either an activating receptor (MP1-CAR) for a MAGE-A3 activating ligand or the activating receptor and a blocking receptor (ESO-Tmod) for a NY-ESO-1 blocking ligand.
[0465] Panel A shows the NFAT-luciferase signal of Jurkat cells transfected with either the activator alone or in combination with the blocker, after 6 hours of co-culture with activator and blocker peptide-loaded T2 cells. The T2 cells were loaded with titrated amounts of activator MAGE-A3 peptide and a fixed amount of blocker NY-ESO-1 peptide concentration. This reveals the activation dose-response of the transfected cells.
[0466] Panel B shows the NFAT-luciferase signal of Jurkat cells transfected with either the activator alone or in combination with the blocker, after 6 hours of co-culture with activator and blocker peptide-loaded T2 cells. The T2 cells were loaded with titrated amounts of blocker NY-ESO-1 peptide and a fixed amount of activator MAGE-A3 peptide concentration above the Emax concentration (.about.0.1 .mu.M). This reveals the inhibition dose-response of the transfected cells.
[0467] Panel C shows the NFAT-luciferase signal of Jurkat cells transfected with either the activator alone or in combination with the blocker, after 6 hours of co-culture with activator and blocker peptide-loaded T2 cells. The x-value blocker NY-ESO-1 peptide concentrations from panel B were normalized to the constant activator MAGE peptide concentrations used for each curve and plotted on the x-axis. The ratio of blocker peptide to activator peptide required for 50% blocking (IC50) are indicated for each curve. The B:A peptide ratio required is less than 1 indicating that, for this pair of activator CAR and blocker, similar (or fewer) blocker pMHC antigens may be sufficient on target cells to block activator pMHC antigens.
[0468] Since this ratio is less than 1, it can be inferred that the blocking signal dominates and inhibits the activating signal. Thus, a single blocking receptor can provide a blocking signal of sufficient strength to inhibit the activating signal of one or more activating receptors. As such, the quantity of activating and blocking ligands expressed by a non-target cell can form part of the basis for determining the appropriate relative amounts of activating and blocking receptors that should be expressed by an immune cell of the disclosure.
Example 6
[0469] FIG. 23 provides experimental results showing that the blocking receptors are ligand-dependent. For both CAR and TCR activating receptors, blocking receptors had minimal ligand-independent blocking activity. This impact is shown by the minimal effect on the EC.sub.50 of the activating receptors by the blocking receptor in the presence/absence of the blocking ligand.
Example 7
[0470] FIG. 25 provides experimental results showing the relative impact hinge length and flexibility has on the strength of a blocking receptor as a function of the EC.sub.50 of the activating receptor.
Example 8
[0471] FIG. 26 shows the large relative impact of the LBD on the activating receptor's structure activity relationship when compared with the effects provided by different hinges, transmembrane and intracellular domains. In this study, 45 separate activating receptors were created using various combinations of ligand binding domains, hinges, and intracellular domains. For each receptor one of five ligand binding domains that bind to the same activating ligand were selected. Despite all binding to the same target ligand, the identity of the ligand binding domain caused differences in the EC.sub.50 of the activating receptors that spanned orders of magnitude. The ligand binding domain was shown to have greater than 10.times. the impact on the receptors' EC.sub.50 compared to the hinge, transmembrane and intracellular domains.
Example 9
[0472] FIGS. 33-34 show the impact receptor cross-talk can have on the ability of the blocking receptor to inhibit the activation signal. Engineered immune cells were created with one of five different activating receptors. Though the activating receptors differed between the cells, each targeted the same activating ligand, epidermal growth factor receptor (EGFR), using a different LBD. As shown by five graph panels FIGS. 33-34, each of the different activating receptors provided the immune cells with equivalent abilities to kill target cells. Then, immune cells were created that had one of the five activating receptors and the same blocking receptor. Addition of the blocker caused some of the immune cells, like CT486-containing cells, to decrease their ability to kill target cells.
