[0001] Priority claim This application claims priority to U.S. Provisional Application No. 63 / 398,834, filed August 17, 2022, the entire contents of which are incorporated herein by reference. [Background technology]
[0002] Targeted therapies, including adoptive cell therapies such as chimeric antigen receptor T cells (CAR T), have revolutionized cancer treatment. These cell therapies can be autologous (CAR T cells manufactured using the patient's own T cells) or allogeneic (CAR T cells manufactured using T cells from a healthy donor). Currently, there are no autologous CAR T therapies approved to treat HER2-specific cancers.
[0003] Although revolutionary in their ability to treat targeted hematological cancers, challenges have arisen in the clinical use of autologous CAR-T cells since the U.S. Food and Drug Administration approved the first CAR-T therapy targeting CD19 B-cell malignancies in 2017. CAR-T cell manufacturing is a resource-intensive process, which may not produce an autologous cell therapy suitable for some patients. The average three-week manufacturing time required for autologous CAR-T cell products may be too long for severely ill patients. Finally, the complex nature of CAR-T cell manufacturing and delivery, which requires close monitoring at top-tier cancer centers and medical institutions, may limit financial and geographic accessibility to this treatment option for most patients. Importantly, even for patients who have access to this innovative therapy, CAR-T cell products carry the risk of serious and potentially fatal side effects. These side effects include cytokine release syndrome (CRS) and neurotoxicity, which can be difficult to manage or control.
[0004] Allogeneic CAR-T cell therapies, which use cells from healthy donors, can overcome some of the manufacturing and logistical challenges of autologous CAR-T cell therapies. However, these "off-the-shelf" CAR-T cell therapies also have issues, such as a potentially high risk of graft-versus-host disease (GVHD) and inefficiency due to rapid clearance by the patient's immune system.
[0005] Natural killer (NK) cells are cytolytic immune cells of the innate immune system that have the unique ability to lyse tumor cells and virus-infected cells. NK cells have the unique ability to initiate innate and multiclonal adaptive immune responses and generate long-term anti-cancer immune memory. Importantly, NK cells do not require prior antigen exposure to identify and lyse tumor cells. Receptor binding on NK cells promotes effector function by degranulating lytic granules, activating programmed cell death receptors on target cells, and secreting immunoregulatory cytokines. The effector function of natural killer cells is regulated by the balance of activating and inhibitory receptor signals. Generally, natural killer cells express CD56 + and CD3 - cells, defined as CD56 bright CD16 - Cytokine-secreting cells and CD56 dim CD16 + NK cells are subdivided into cytolytic and cytolytic cells. Binding of CD16 to antibody-labeled tumor cells is sufficient to induce cytotoxic and cytokine-releasing responses in resting NK cells. Activated NK cells secrete cytokines and chemokines, such as interferon gamma (IFNγ), tumor necrosis factor alpha (TNFα), and macrophage inflammatory protein 1 (MIP1), to signal tumors and recruit T cells. NK cells directly kill tumor cells, exposing tumor antigens for recognition by the adaptive immune system. Natural killer cells also bind to tumor cells through antibody-dependent cellular cytotoxicity (ADCC). To initiate ADCC, NK cells bind antibodies via their surface CD16 receptor.
[0006] Natural killer cells also bind to tumor cells through antibody-dependent cellular cytotoxicity (ADCC), a core component of the innate immune system. Antibody-coated target cells are killed by cells bearing Fc receptors that recognize specific regions of the bound antibody. Binding of antibody-opsonized tumor cells to CD16 (FCγRIII) is sufficient to induce cytotoxic and cytokine-releasing responses from resting NK cells. Activated NK cells secrete cytokines and chemokines, such as interferon gamma (IFNγ), tumor necrosis factor alpha (TNFα), and macrophage inflammatory protein 1 (MIP1), to signal tumors and recruit T cells. NK cells also directly kill tumor cells, exposing tumor antigens for recognition by the adaptive immune system. ADCC, particularly with antibodies belonging to the immunoglobulin G1 (IgG1) and IgG3 subclasses, is recognized as a powerful mechanism of NK cell action. To initiate ADCC, NK cells bind antibodies via the CD16 receptor.
[0007] Like T cells, allogeneic NK cells genetically modified to express CARs with antitumor activity can provide an important treatment option for cancer patients. NK cells are free from the drawbacks of allogeneic CAR-T cells, which maintain expression of endogenous T cell receptors in addition to genetically modified chimeric antigen receptors. As a result, allogeneic CAR-NK cell therapy can be safely administered to patients without many of the risks associated with allogeneic T cell therapy, including graft-versus-host disease. However, CAR-NK cells face many of the same challenges as other allogeneic cell therapies, including product sourcing, scalability, persistence, and dose-to-dose variability.
[0008] HER2, also known as human epidermal growth factor receptor 2 or ErbB2, is a receptor tyrosine kinase highly expressed on the surface of many solid tumors. Although HER2 plays an important role in cell development in normal cells, mutations or overexpression of HER2 can directly lead to tumor initiation and metastasis.
[0009] HER2 amplification, which is considered a key signal in tumorigenesis, is common in a variety of solid tumors, including 20-30% overexpression in human breast, ovarian, and gastric cancers.
[0010] Currently, eight HER2-targeted therapeutic agents are approved for cancer patients. These FDA-approved drugs include monoclonal antibodies, antibody-drug conjugates (ADCs), and small-molecule tyrosine kinase inhibitors (TKIs). In existing therapies for HER2-positive cancers, such as trastuzumab or lapatinib, downstream signaling mutations can lead to resistance to tumor growth inhibition. One of the mechanisms of action of trastuzumab is by inhibiting the MAPK and PI3K / Akt pathways, which lead to cell cycle arrest. Mutations including those that induce loss of PTEN (phosphatase and tensin homolog) and activating mutations in PIK3CA (phosphatidylinositol 3-kinase) can confer resistance to trastuzumab treatment. These mutations can constitutively activate the PI3K / Akt pathway, which induces cell proliferation. PTEN loss was observed in 36% of HER2-positive primary breast cancer specimens (stage 4), and these patients had a lower overall response rate to trastuzumab. Additionally, approximately 25% of trastuzumab-resistant patients have PIK3CA mutations. Patients with PI3KCA mutations had significantly shorter progression-free survival times after trastuzumab treatment than patients without mutations. Therefore, while many patients achieve meaningful benefit from trastuzumab, a significant number of patients eventually experience recurrence or disease progression. Once all HER2-targeted therapies have been exhausted, patients are left with only marginally effective cytotoxic chemotherapy. The lack of safe and effective treatments for patients who have exhausted all HER2-targeted treatment options continues to highlight the need for their development.
[0011] The present invention seeks to overcome these disadvantages of the prior art. Summary of the Invention
[0012] NK cells are immune cells that can bind to tumor cells through a complex array of receptors on their cell surface and antibody-dependent cellular cytotoxicity (ADCC). NK cells have several advantages over other immune cells, such as T cells, used in CAR-T cell therapy. Autologous CAR-T cells must be engineered using the patient's own cells, but this engineering process is time-consuming and can significantly progress the patient's disease during that time. Therefore, patients may require bridging therapy to maintain treatment until autologous CAR-T cells are ready. Not all patients are suitable for autologous CAR-T therapy. For example, some patients may have severe symptoms or insufficient numbers of T cells suitable for engineering purposes. Autologous CAR-T cell production does not always produce sufficient cell numbers or sufficiently active cells for therapeutic efficacy. If such production is successful, patients generally receive only a single autologous CAR-T treatment. Because the risk of acute side effects such as ICANS and CRS is greatest immediately after CAR-T cell administration, repeated administrations can potentially be dangerous if patients experience only modest benefits from a second, third, or subsequent administration. In addition, autologous CAR-T therapy is individualized to each patient, which places a heavy financial burden on the patient.
[0013] NK cells offer a key advantage as an allogeneic therapy: NK cells from a single donor can be safely used in one or more other patients without the need for HLA matching, gene editing, or other genetic manipulation. This advantage allows allogeneic CAR-NK cells to be mass-produced, cryopreserved, and distributed worldwide for administration at the point of care as needed. Therefore, allogeneic cell therapies can be administered immediately to patients without cross-linking therapy, eliminating the need to wait for the manipulation and administration of the patient's own cells. Because the allogeneic therapies described herein can be mass-produced using campaign manufacturing methods, the costs associated with manufacturing and delivering the allogeneic therapies described herein are expected to be significantly lower than those of autologous CAR-T therapies. Campaign manufacturing also reduces batch-to-batch variability, allowing a single batch of CAR-NK cells extracted from a single donor to be administered multiple times if desired by the patient.
[0014] Providing repeated administrations allows patients to achieve or maintain a higher or extended therapeutic response to treatment. For example, patients can receive response-based dosing, during which they continue to receive CAR-NK cell therapy as long as they benefit. Additionally, the number of cells administered in each dose and the number of doses can be tailored to the individual patient. In this case, patients are not limited to the number of cells as in autologous CAR-T therapy. Thus, the CAR-NK cell therapy described herein can be tailored to each patient based on their own response. In some cases, if a patient relapses, treatment can be initiated again.
[0015] Allogeneic NK cells may be an important treatment option for cancer patients. One exemplary advantage is that NK cells are well tolerated without the side effects of graft-versus-host disease, neurotoxicity, or cytokine release syndrome associated with other cell-based therapies. Another exemplary advantage is that NK cells do not require prior antigen exposure to recognize and lyse tumor cells. Yet another exemplary advantage is that NK cells have the intrinsic ability to initiate innate and polyclonal adaptive immune responses and generate long-term anti-cancer immune memory. All of these characteristics make NK cells a potential treatment option for cancer.
[0016] For example, NK cells can recruit and activate other components of the immune system. Activated NK cells secrete cytokines and chemokines, such as interferon gamma (IFNγ), tumor necrosis factor alpha (TNFα), and macrophage inflammatory protein 1 (MIP-1), to signal and recruit T cells to tumors. NK cells can also directly kill tumor cells, exposing tumor antigens for recognition by the adaptive immune system.
[0017] Furthermore, by utilizing diverse cord blood banks as a source of NK cells, cord blood units with favorable characteristics (e.g., high-affinity CD16 and KIR (Killer cell immunoglobulin-like receptor) B-haplotypes) can be selected to improve clinical activity.
[0018] Genetically engineered NK cells, such as the CAR-NK cells referred to herein, have the advantage over autologous cell therapies, such as the T cells used in CAR-T cell therapy, because they can be used as an allogeneic therapy. Thus, NK cells from one donor can be safely used in one or more other patients.
[0019] In existing Her2-positive cancer therapies, such as trastuzumab or lapatinib, mutations can lead to resistance to tumor growth inhibition. As explained above, some mutations alter downstream signaling pathways, rendering cells resistant to trastuzumab or lapatinib. Unlike trastuzumab or lapatinib, the HER2-guided CAR-NK cells and therapies such as AB-201 described herein are activated by binding to HER2 expressed on the surface of target cells. Activated CAR-NK cells kill target cells using their own cytotoxic pathways. Therefore, such killing occurs independently of the integrity of intracellular signals within the target cells. Therefore, the CAR-NK cell therapeutics described herein maintain their ability to kill HER2-positive tumor cells, even in the presence of some downstream signaling mutations that confer resistance to approved HER2 therapeutics. Other mutations may alter the epitopes to which trastuzumab or lapatinib bind, reducing the efficacy of these drugs. For example, the HER2-targeting CAR-NK scFv described herein, comprising the scFv of SEQ ID NO: 30, binds to a different domain of HER (domain I) than trastuzumab (domain IV) or lapatinib (domain II), such that the CAR-NK cells described herein can maintain their effectiveness in binding to HER2-positive cells even if other mutations reduce or inhibit the binding ability of trastuzumab or lapatinib.
[0020] Additionally, the CAR-NK cells described herein can maintain expression of CD16, including expression of the 158V / V variant of CD16. Thus, in some cases, CAR-NK cells can be used in conjunction with traditional antibody therapy. As an example, antibody therapy may consist of trastuzumab or lapatinib. Alternatively, or in combination, antibody therapy can target alternative or additional targets, including, for example, EGFR. Examples of anti-EGFR antibodies include cetuximab, panitumumab, nimotuzumab, and necitumumab. Such antibodies can bind to CD16 expressed on the surface of NK cells and induce an ADCC response from the NK cells. Thus, in some cases, therapeutic methods can include a dual-target approach that combines the use of the HER2-targeting CAR-NK cells described herein with anti-EGFR antibody therapy.
[0021] Accordingly, the present invention provides a method comprising administering to a patient between 1 million and 100 billion natural killer (NK) cells, wherein the NK cells comprise: a) a nucleic acid encoding an anti-human epidermal growth factor receptor 2 (HER2) chimeric antigen receptor (CAR) comprising an extracellular antigen-binding domain comprising an anti-HER2 antibody or antigen-binding fragment thereof; and b) a polynucleotide comprising a nucleic acid encoding IL-15.

In one embodiment, the ratio of feeder cells to natural killer cell source cells or MCB cells inoculated into the co-culture is about 2.5:1.
[0397] In one embodiment, the co-culture is carried out in a disposable culture bag (e.g., a 1 L disposable culture bag). In one embodiment, the co-culture is carried out in a bioreactor (e.g., a 50 L bioreactor). In one embodiment, culture medium is added to the co-culture after the initial inoculation.

For example, in some cases, the engineering (e.g., transduction) occurs during the expansion and stimulation process described herein, e.g., co-culturing the NK cell source with support cells as described herein, e.g., on day 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, or 18 of co-culture.
[0427] In one embodiment, the method of the invention additionally comprises the step of engineering the NK cells, eg, to express, overexpress, knock out, or knock down a gene or gene product.
[0428] In one embodiment, the natural killer cells are not genetically engineered.
[0429] In one embodiment, NK cells are engineered (e.g., transduced) in culture medium supplemented with stimulatory factors (e.g., as described herein). Such stimulatory factors can be used to provide growth or survival signals to NK cells during the engineering process or to increase transcription efficiency. In one embodiment, the stimulatory factor is a cytokine. In one embodiment, the cytokine is selected from the group consisting of IL-2, IL-12, IL-15, IL-18, IL-21, IL-23, IL-27, IFN-α, IFN-β, and combinations thereof.
[0430] In one embodiment, the cytokine is IL-21. IL-21 is used at a final concentration of 10-100 ng / mL, for example, at a final concentration of about 10, 15, 20, 25, 30, 34, 40, 45, 50, 55, 60, 70, 80, 90, or 100 ng / mL, or at a final concentration of about 10, 15, 20, 25, 30, 34, 40, 45, 50, or 10-100 ng / mL. In one embodiment, the cytokine is IL-2. In one embodiment, the cytokine is a combination of IL-2 and IL-21. In one embodiment, the cytokine is a combination of IL-2, IL-18, and IL-21.
[0431] In one embodiment, the stimulatory factor is added to the culture medium at the time of manipulation (e.g., transduction). In one embodiment, the stimulatory factor is added to the culture medium after the time of manipulation (e.g., transduction), for example, 1 to 48 hours after manipulation, for example, 1 to 36 hours, 1 to 24 hours, 1 to 12 hours, 12 to 28 hours, 12 to 36 hours, 12 to 24 hours, 24 to 48 hours, 24 to 36 hours, or 36 to 48 hours after manipulation. In one embodiment, the stimulatory factor is added to the culture medium at the time of transduction and all times after the time of manipulation (e.g., 1 to 48 hours after transduction).
[0432] In one embodiment, the culture medium is supplemented with stimulatory factors after culturing in medium containing feeder cells. Thus, in some cases, the culture medium can include feeder cells at the time of manipulation (e.g., transduction). In some cases, the feeder cells are removed from the culture medium before supplementing or manipulating with stimulatory factors. In some cases, the feeder cells are not removed from the culture medium before supplementing or manipulating with stimulatory factors. In some cases, no additional feeder cells are added to the culture medium during manipulation, regardless of whether or not residual feeder cells are removed. In some cases, all additional feeder cells and stimulatory factors are added to the culture medium during manipulation. In some cases, no additional feeder cells are added during manipulation, but stimulatory factors are added to the culture medium during manipulation.
[0433] Characteristics of expanded and stimulated NK cells For example, after ex vivo expansion and stimulation as described herein, the expanded and stimulated NK cell population not only has a number / density (e.g., as described above) that does not naturally occur in the human body, but also differs in phenotypic characteristics (e.g., gene expression and / or surface protein expression) from the starting source material or other naturally occurring NK cell populations.
[0434] In some cases, the starting NK cell source is a sample extracted from a single individual (e.g., a single umbilical cord blood unit not expanded in vitro). Thus, in some cases, the expanded and stimulated NK cells share a common lineage, i.e., share a genotype due to the clonal expansion of a cell population derived from a single organism, since they all arise by expansion of the starting NK cell source. However, they would not arise naturally at the densities achieved by in vitro expansion and have different phenotypic characteristics from the starting NK cell source.
[0435] In some cases, the population of expanded stimulated NK cells comprises a minimum of 100 million or more expanded natural killer cells, e.g., 200 million, 250 million, 300 million, 300 million, 400 million, 500 million, 600 million, 700 million, 750 million, 800 million, 800 million, 900 million, 1 billion, 2 billion, 3 billion, 4 billion, 5 billion, 6 billion, 7 billion, 8 billion, 9 billion, 10 billion, 15 billion, 20 billion, 25 billion, 50 billion, 75 billion, 80 billion, 9 billion, 10 billion, 20 billion, 25 billion, 30 billion, 40 billion, 50 billion, 60 billion, 70 billion, 80 billion, 90 billion, 1 trillion, 2 trillion, 3 trillion, 4 trillion, 5 trillion, 6 trillion, 7 trillion, 8 trillion, 9 trillion, or 10 trillion expanded natural killer cells.
[0436] In one embodiment, the expanded and stimulated NK cells comprise at least 80%, eg, at least 90%, at least 95%, at least 99% or 100% CD56+CD3- cells.
[0437] In one embodiment, the expanded and stimulated NK cells are not genetically engineered.
[0438] In one embodiment, the expanded and stimulated NK cells do not contain the CD16 transforming gene.
[0439] In one embodiment, the expanded and stimulated NK cells do not express exogenous CD16 protein.
[0440] For example, expanded and stimulated NK cells express one or more of CD16, CD56, CD3, CD38, CD14, CD19, NKG2D, NKp46, NKp30, DNAM-1, and NKp44 on their surface.
[0441] In the present invention, surface protein expression levels can be achieved in some cases without positive selection for a particular surface protein. For example, in some cases, the NK cell source (e.g., a single cord blood unit) contains all KIR B alleles of the KIR receptor system and the 158V / V variant of CD16, and is enriched for CD56+CD3- expression and depleted of CD3(+), but without selection for other surface protein expression during expansion and stimulation.
[0442] In one embodiment, the NK cells expanded and stimulated, e.g., by expansion and stimulation of a single cord blood unit as described above, comprise at least 60%, e.g., at least 70%, at least 80%, at least 90%, at least 95%, at least 99%, or 100% NKG2D+ cells.
[0443] In one embodiment, the NK cells expanded and stimulated, e.g., by expansion and stimulation of a single cord blood unit as described above, comprise at least 60%, e.g., at least 70%, at least 80%, at least 90%, at least 95%, at least 99%, or 100% NKp46+ cells.
[0444] In one embodiment, the NK cells expanded and stimulated, e.g., by expansion and stimulation of a single cord blood unit as described above, comprise at least 60%, e.g., at least 70%, at least 80%, at least 90%, at least 95%, at least 99%, or 100% NKp30+ cells.
[0445] In one embodiment, the NK cells expanded and stimulated, e.g., by expansion and stimulation of a single cord blood unit as described above, comprise at least 60%, e.g., at least 70%, at least 80%, at least 90%, at least 95%, at least 99%, or 100% DNAM-1+ cells.
[0446] In one embodiment, the NK cells expanded and stimulated, e.g., by expansion and stimulation of a single cord blood unit as described above, comprise at least 60%, e.g., at least 70%, at least 80%, at least 90%, at least 95%, at least 99%, or 100% NKp44+ cells.
[0447] In one embodiment, the expanded and stimulated NK cells, e.g., by expansion and stimulation of a single cord blood unit as described above, can comprise at least 60%, e.g., at least 70%, at least 80%, at least 90%, at least 95%, at least 99%, or 100% CD94+(KLRD1) cells; in one embodiment, the expanded and stimulated NK cells, e.g., by expansion and stimulation of a single cord blood unit as described above, can comprise at least 60%, e.g., at least 70%, at least 80%, at least 90%, or 100% CD94+(KLRD1) cells.
[0448] In one embodiment, the NK cells expanded and stimulated, e.g., by expansion and stimulation of a single cord blood unit as described above, comprise 20% or less, e.g., 10% or less, 5% or less, 1% or less, or 0% CD3+ cells.
[0449] In one embodiment, the NK cells expanded and stimulated, e.g., by expansion and stimulation of a single cord blood unit as described above, contain 20% or less, e.g., 10% or less, 5% or less, 1% or less, or 0% CD14+ cells.
[0450] In one embodiment, the NK cells expanded and stimulated, e.g., by expansion and stimulation of a single cord blood unit as described above, contain 20% or less, e.g., 10% or less, 5% or less, 1% or less, or 0% CD19+ cells.
[0451] In one embodiment, the NK cells expanded and stimulated, e.g., by expansion and stimulation of a single cord blood unit as described above, contain 20% or less, e.g., 10% or less, 5% or less, 1% or less, or 0% CXCR+ cells.
[0452] In one embodiment, the NK cells expanded and stimulated, e.g., by expansion and stimulation of a single cord blood unit as described above, contain 20% or less, e.g., 10% or less, 5% or less, 1% or less, or 0% CD122+(IL2RB) cells.
[0453] As described herein, the inventors have surprisingly demonstrated that NK cells expanded and stimulated by the methods described herein express high levels of CD16 throughout the expansion and stimulation process, producing a cell population with high CD16 expression. The high expression of CD16 obviates the need to engineer the expanded cells to express CD16, which is important for initiating ADCC, thereby providing an unexpected advantage of the expansion and stimulation methods disclosed herein. Thus, in one embodiment, for example, by expansion and stimulation of a single cord blood unit, e.g., as described above, the expanded and stimulated NK cells comprise 50% or more, e.g., 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, or 95% CD16+ NK cells.
[0454] In one embodiment, for example, by expansion and stimulation of a single cord blood unit as described above, the expanded and stimulated NK cells comprise 50% or more, e.g., 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90% or 95% of all CD16+ NK cells bearing KIR B alleles and CD16 and 158V / V variants of the KIR receptor system.
[0455] In one embodiment, e.g., from expansion and stimulation of a single cord blood unit as described above, the proportion of expanded and stimulated NK cells expressing, e.g., CD16, is the same as or higher than the proportion of NK cells in the cord blood-derived seed cells.
[0456] In one embodiment, e.g., from expansion and stimulation of a single cord blood unit as described above, the proportion of expanded and stimulated NK cells expressing, e.g., NKG2D, is the same as or higher than the proportion of natural killer cells in the cord blood-derived source cells.
[0457] In one embodiment, e.g., from expansion and stimulation of a single cord blood unit as described above, the proportion of expanded and stimulated NK cells that express, e.g., NKp30, is the same as or higher than the proportion of NK cells in the cord blood-derived source cells.
[0458] In one embodiment, for example, the proportion of expanded and stimulated NK cells expressing DNAM-1 from expansion and stimulation of a single cord blood unit (e.g., as described above) is the same as or higher than the proportion of NK cells in cord blood-derived source cells.
[0459] In one embodiment, the proportion of expanded and stimulated NK cells, e.g., expressing NKp44, from expansion and stimulation of a single cord blood unit (e.g., as described above) is the same as or higher than the proportion of NK cells in the cord blood-derived source cells.
[0460] In one embodiment, the proportion of expanded and stimulated NK cells, e.g., expressing NKp46, from expansion and stimulation of a single cord blood unit (e.g., as described above) is the same as or higher than the proportion of NK cells in the cord blood-derived source cells.
[0461] As described herein, the inventors have also surprisingly demonstrated that NK cells expanded and stimulated by the methods described herein express low levels of CD38, which is an effective target for certain cancer therapies (e.g., multiple myeloma and acute myeloid leukemia) (see Jiao et al., "CD38: Targeted Therapy in Multiple Myeloma and Therapeutic Potential for Solid Cancers," Expert Opinion on Investigational Drugs 29(11):1295-1308 (2020)).
[0462] Thus, in one embodiment, the NK cells expanded and stimulated, e.g., by expansion and stimulation of a single cord blood unit as described above, contain no more than 80% or the same CD38+ cells, e.g., no more than 75%, 70%, 65%, 60%, 55%, 50%, 45%, 40%, 35%, 30%, 25% or 20% CD38+ cells.
[0463] In one embodiment, the NK cells expanded and stimulated, e.g., by expansion and stimulation of a single cord blood unit as described above, contain all KIR B alleles of the KIR receptor system and the 158V / V variant of CD16, and comprise no more than 80% CD38+ cells, e.g., no more than 75%, 70%, 65%, 60%, 55%, 50%, 45%, 40%, 35%, 30%, 25% or 20% CD38+ cells.
[0464] In one embodiment, e.g., from expansion and stimulation of a single cord blood unit, e.g., as described above, the expanded and stimulated NK cells contain all KIR B alleles of the KIR receptor system and the 158V / V variant of CD16, and are composed of up to 80% or identical CD38+ cells, e.g., 75%, 70%, 65%, 60%, 55%, 50%, 45%, 40%, 35%, 30%, 25%, or 20% CD38+ cells and 50% or more (e.g., 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90% or 95% CD16+ NK cells).
[0465] In one embodiment, e.g., from expansion and stimulation of a single cord blood unit, e.g., as described above, the expanded and stimulated NK cells contain all KIR B alleles of the KIR receptor system and 158V / V mutations of CD16, and include: i) 50% or more, e.g., 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90% or 95% CD16+ NK cells; and / or ii) less than or equal to 80% CD38+ cells, e.g., 75%, 70%, 65%, 60%, 55%, 50%, 45%, 40%, 35%, 30%, 25% or 20% CD38+ cells; and / or iii) at least 60%, e.g., at least 70% CD38+ cells. 0%, at least 80%, at least 90%, at least 95%, at least 99% or 100% NKG2D+ cells; and / or iv) at least 60%, e.g., at least 70%, at least 80%, at least 90%, at least 95%, at least 99% or 100% NKp46+ cells; and / or v) at least 60%, e.g., at least 70%, at least 80%, at least 90%, at least 95%, at least 99% or 100% NKp30+ cells; and / or vi) at least 60%, e.g., at least 70%, at least 80%, at least 90% and / or vii) at least 95%, minimum 99%, or 100% DNAM-1+ cells; and / or vii) minimum 60%, e.g., minimum 70%, minimum 80%, minimum 90%, minimum 95%, minimum 99%, or 100% NKp44+ cells; and / or viii) minimum 60%, e.g., minimum 70%, minimum 80%, minimum 90%, minimum 95%, minimum 99%, or 100% CD94+ (KLRD1) cells; and / or ix) 20% or less, e.g., 10% or less, 5% or less, 1% or less, or 0% CD94+ (KLRD1) cells. and / or x) 20% or less, e.g., 10% or less, 5% or less, 1% or 0% CD14+ cells; and / or xi) 20% or less, e.g., 10% or less, 5% or less, 1% or 0% CD19+ cells; and / or xii) 20% or less, e.g., 10% or less, 10% or less, 5% or less, 1% or 0% or less CXCR+ cells; and / or xiii) 20% or less (e.g., 10% or less, 5% or less, 1% or 0% or less CD122+ (IL2RB) cells.
[0466] In one embodiment, the supporting cells do not persist with the expanded and stimulated NK cells, but residual signals of the supporting cells can be detected, for example, by the presence of residual cells (e.g., detection of cells with specific surface protein expression) or detection of residual nucleic acids and / or proteins expressed by the supporting cells.
[0467] For example, in some cases, the methods of the invention include expanding and stimulating NK cells using support cells, e.g., the eHuT-78 support cells described above, engineered to express a sequence not expressed by cells of the NK cell source, including the NK cells. For example, the support cells can be engineered to express at least one gene selected from the group consisting of 4-1BBL (UniProtKB P41273, SEQ ID NO: 1), membrane-bound IL-21 (SEQ ID NO: 2), and mutant TNFα (SEQ ID NO: 3) or a variant thereof ("eHut-78 cells").
[0468] Such supporting cells may not remain in the expanded and stimulated NK cells, but the expanded and stimulated NK cells may contain detectable amounts of cells, proteins, and / or nucleic acids from the feeding cells. Thus, their residual presence can be detected in the expanded and stimulated NK cells, for example, by detecting the cells themselves (e.g., by flow cytometry), proteins expressed by the cells, and / or nucleic acids expressed by the cells.
[0469] Thus, the present specification also describes populations of expanded and stimulated NK cells that contain feeder cells (living or dead cells) or residual feeder cell impurities (e.g., residual feeder cell proteins or portions thereof and / or genetic material such as nucleic acids or portions thereof), and in some cases, the expanded and stimulated NK cells can contain more than 0% but less than 0.3% residual feeder cells (e.g., eHuT-78 feeder cells).
[0470] In some cases, the expanded and stimulated NK cells comprise residual feeder cell nucleic acid, e.g., residual 4-1BBL (UniProtKB P41273, SEQ ID NO: 1), membrane-bound IL-21 (SEQ ID NO: 2) and / or mutated TNFα (SEQ ID NO: 3), or portions thereof. In some cases, the membrane-bound IL-21 comprises the CD8 transmembrane domain.
[0471] In some cases, the expanded and stimulated NK cells comprise a proportion of residual supporting cells that is greater than or equal to 0% and less than or equal to 0.2%, e.g., as measured by the relative proportion of a particular protein or nucleic acid sequence of supporting cells in the sample (i.e., a protein or nucleic acid sequence not expressed by natural killer cells). For example, this can be measured by qPCR, as described above.
[0472] In one embodiment, the residual support cells are CD4(+) T cells. In one embodiment, the residual support cells are engineered CD4(+) T cells. In one embodiment, the residual support cells are engineered to express at least one gene selected from 4-1BBL (UniProtKB P41273, SEQ ID NO: 1), membrane-bound IL-21 (SEQ ID NO: 2), and mutated TNFα (SEQ ID NO: 3) ("eHut-78 cells") or variants thereof. Thus, in some cases, the support cell-specific protein is 4-1BBL (UniProtKB P41273, SEQ ID NO: 1), membrane-bound IL-21 (SEQ ID NO: 2), and / or mutated TNFα (SEQ ID NO: 3). Thus, the support cell-specific nucleic acid is a nucleic acid encoding 4-1BBL (UniProtKB P41273, SEQ ID NO: 1), membrane-bound IL-21 (SEQ ID NO: 2), and mutated TNFα (SEQ ID NO: 3), or a portion thereof. In some cases, the membrane-bound IL-21 comprises a CD8 transmembrane domain.
[0473] A variety of methods can be used to analyze and detect the presence of nucleic acid or protein gene products in biological samples. As used herein, the term "detection" refers to a method used to discover, determine, or confirm the presence or absence of a compound and / or substance (e.g., a cell, a protein, and / or a nucleic acid). In one embodiment, the detection method can be used to detect proteins. In one embodiment, detection can involve chemiluminescent or fluorescent techniques. In one embodiment, detection can involve immunological-based methods (e.g., quantitative enzyme-linked immunosorbent assays (ELISA), Western blotting, or dot blotting) in which antibodies are used to specifically react with whole proteins or specific epitopes of proteins. In one embodiment, detection can involve immunoprecipitation of proteins (Jungblut et al., J Biotechnol. 31;41(2-3):111-20 (1995); Franco et al., Eur J Morphol. 39(1):3-25 (2001)). In one embodiment, the detection method can be used to detect nucleic acids (e.g., DNA and / or RNA). In one embodiment, detection can involve Northern blot analysis, nuclease protection assay (NPA), in situ hybridization, or reverse transcription polymerase chain reaction (RT-PCR) (Raj et al., Nat. Methods 5, 877-879 (2008); Jin et al., J Clin Lab Anal. 11(1):2-9 (1997); Ahmed, J Environ Sci Health C Environ Carcinog Ecotoxicol Rev. 20(2):77-116 (2002)).
[0474] Accordingly, methods for detecting a population of expanded and stimulated NK cells expanded and stimulated by the methods of the invention, e.g., co-cultured with eHuT-78 feeder cells described herein, are also described herein.
[0475] Anti-HER2 CAR-NK Provided herein are engineered cells, e.g., engineered natural killer cells, e.g., CAR-NK cells, e.g., anti-HER2 CAR-NK cells. In one embodiment, the CAR-NK cells are engineered to express IL-15.

[0479] In one embodiment, NK cells are transformed at an MOI (multiplicity of infection) of about 1 to about 40 viral particles per cell. In one embodiment, NK cells are transformed at an MOI of about 1, about 5, about 10, about 15, about 20, about 25, about 30, about 35, or about 40 viral particles per cell.

[0587] In one embodiment, the pharmaceutical composition additionally comprises an antibody or antigen-binding fragment thereof, eg, an antibody described herein.
[0588] Pharmaceutical compositions are generally prepared to be compatible with their intended route of administration, including parenteral (e.g., intravenous, intradermal, subcutaneous), oral (e.g., inhalation), transdermal (topical), transmucosal, and rectal administration.
[0589] Methods for preparing suitable pharmaceutical compositions are known to those skilled in the art and are described, for example, in Remington: The Science and Practice of Pharmacy, 21 sted., 2005; and references in Drugs and the Pharmaceutical Sciences: a Series of Textbooks and Monographs (Dekker, NY). For example, solutions or suspensions used for parenteral, intradermal, or subcutaneous application may contain the following components: a sterile diluent such as water for injection, saline, fixed oil, polyethylene glycol, glycerin, propylene glycol, or other synthetic solvents; an antibacterial agent such as benzyl alcohol or methylparaben; an antioxidant such as ascorbic acid or sodium bisulfite; a chelating agent such as ethylenediaminetetraacetic acid; a buffer such as acetate, citrate, or phosphate; and a tonicity adjusting ingredient such as sodium chloride or dextrose. pH can be adjusted with acids or bases such as hydrochloric acid or sodium hydroxide. Parenteral preparations can be enclosed in ampoules, disposable syringes, or multi-dose vials made of glass or plastic.
[0590] Pharmaceutical compositions suitable for injection may include sterile aqueous solutions (where water soluble) or dispersions and sterile powders, or sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. Suitable vehicles for intravenous administration include physiological saline, bacteriostatic water, Cremophor EL® (BASF, Parsippany, NJ), or phosphate-buffered saline (PBS). In all cases, the composition must be sterile and fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier may be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol, liquid polyethylene glycol, and the like), and suitable mixtures thereof. Proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants. Prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents, such as parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like. In most cases, it is preferable to include isotonic agents (e.g., sugars, polyalcohols such as mannitol, sorbitol, sodium chloride) in the composition. Prolonged absorption of the injectable compositions can be brought about by including in the composition agents that delay absorption, for example, aluminum monostearate and gelatin.
[0591] Sterile injectable solution can be prepared by mixing the active compound in the required amount with one or combination of the above-listed components in a suitable solvent, and then sterilizing by filtration.Generally, dispersion is prepared by incorporating active compound into a sterile solvent that contains a basic dispersion medium and other necessary components from the above-listed components.For the preparation of sterile powder for sterile injectable solution, the preferred method of preparation is vacuum drying and freeze-drying, which obtains the powder of active ingredient and the previously sterile-filtered solution that contains the additional desired components.
[0592] Treatment method The NK cells described herein, for example, the CAR-NK cells described herein, are used to treat cancer or other proliferative disorders.
[0593] Thus, the present invention also provides a method of treating a patient suffering from a disease, e.g., a disease associated with cancer, e.g., a HER2-positive cancer, comprising administering an NK cell described in the present invention, e.g., a CAR-NK cell described in the present invention.
[0594] The present invention also provides a method for preventing, reducing, and / or inhibiting the recurrence, growth, proliferation, migration, and / or metastasis of a cancer cell or population of cancer cells, comprising administering an NK cell described in the present invention, e.g., a CAR-NK cell described in the present invention.
[0595] The present invention also provides a method of enhancing, improving, and / or increasing response to anti-cancer therapy in a subject in need thereof, comprising administering an NK cell described in the present invention, e.g., a CAR-NK cell described herein.
[0596] Furthermore, the present invention provides a method for inducing the immune system in a subject in need thereof, comprising administering the NK cells described in the present invention, for example, the CAR-NK cells described in the present invention.
[0597] The methods described herein include methods for treating diseases associated with abnormal cell death or differentiation processes, e.g., cell proliferative or cell differentiative diseases, e.g., cancers, including solid tumors and hematological cancers. Generally, the methods involve administering a therapeutically effective amount of a therapeutic agent, as described herein, to a subject in need of or determined to be in need of such treatment. In one embodiment, the method involves administering a therapeutically effective amount of a therapeutic agent comprising NK cells, e.g., CAR-NK cells, as described herein.
[0598] As used herein, the terms "treatment" and "treating" refer to reversing, mitigating, slowing, or inhibiting the progression of a disease associated with abnormal cell death or differentiation processes. For example, treatment may result in a decrease in tumor size or growth rate. Administration of a therapeutically effective amount of a composition described herein for treating a disease associated with abnormal cell death or differentiation processes can result in a decrease in tumor size or growth rate, a decrease in the risk or frequency of recurrence, a delay in recurrence, a decrease in metastasis, an increase in survival, a decrease in morbidity and mortality, and the like. In one embodiment, a therapeutic agent can be administered after one or more symptoms have developed. In other examples, a therapeutic agent can be administered in the absence of symptoms. For example, a therapeutic agent can be administered to a susceptible individual (e.g., based on a history of the condition and / or genetic or other susceptibility factors) before symptoms develop. Treatment can also be continued after symptoms have resolved to prevent or delay recurrence.
[0599] As used herein, the term "inhibit" refers to inhibiting the growth, division, maturation or survival of cancer cells through cytotoxicity, nutrient deprivation or induction of cell death in relation to cancer and / or cancer cell proliferation, or inducing the death of cancer cells, either individually or collectively with other cancer cells.
[0600] As used herein, "delaying" a disease or disorder or one or more symptoms means delaying, inhibiting, slowing, retarding, stabilizing, and / or postponing the onset of the disease, disorder, or symptom. Such delay may occur for a variety of periods depending on the history of the disease and / or the subject being treated. As will be apparent to those skilled in the art, a sufficient or significant delay can include prevention, in that the subject does not actually develop the disease, disorder, or its symptoms. For example, a method for "delaying" the onset of cancer is one that reduces the probability of developing the disease in a given period of time or reduces the severity of the disease in a given period of time compared to not using the method. Such comparisons can be based on clinical studies involving a statistically significant number of subjects.
[0601] As used herein, the terms "prevention" or "preventing" refer to a therapy that prevents the onset of a disease or disorder and prevents the clinical symptoms of the disease from appearing. Thus, "prevention" refers to administering a therapy (e.g., administering a therapeutic agent) to a subject before symptoms of the disease are detected and / or prior to a specific stage of the disease (e.g., administering a therapeutic agent to a subject with cancer that has not yet metastasized). A subject may be an individual at risk of developing a disease or disorder or at risk for disease progression (e.g., cancer metastasis). For example, an individual may have a mutation associated with the onset or progression of cancer. It should be understood that prevention does not completely prevent the onset of a disease or disorder. In some cases, prevention includes reducing the risk of developing a disease or disorder. Such a reduction in risk may not completely eliminate the risk of developing a disease or disorder.
[0602] "Increase" or "enhancement" (e.g., with respect to anti-cancer response, metastasis of cancer cells) means an increase of 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, or 50 fold or more (e.g., 100, 500, 1000 fold) (including all integers and decimal points, e.g., 2.1, 2.2, 2.3, 2.4, etc.). It may also include an increase of at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 100%, at least 150%, at least 200%, at least 500%, or at least 1000% of the amounts or levels described herein.
[0603] A "decrease" or "reduction" or "lesser" amount (e.g., in relation to tumor size, cancer cell proliferation or growth) can mean a decrease of about 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, or 50 or more (e.g., 1, 100, 500, 1000 fold) (including all integers and decimal points, e.g., 1.5, 1.6, 1.7, 1.8, etc.). It can also include a decrease of at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 100%, at least 150%, at least 200%, at least 500%, or at least 1000% of the amounts or levels described herein.
[0604] disease The methods and compositions disclosed herein can be used to target a variety of diseases, such as cell proliferative disorders. An advantage of the approaches of the present invention is that they target specific cells using allogeneic cells. Unlike previous treatments, such as chemotherapy and radiation therapy, the approaches and pharmaceutical compositions disclosed herein can specifically target cells exhibiting potentially harmful proliferative activity without the need for systemic drug or toxin administration, which indiscriminately affect proliferating cells.
[0605] Examples of cell proliferative and / or differentiative disorders include cancer (e.g., carcinoma, sarcoma), metastatic disease, or hematopoietic neoplastic disorders (e.g., leukemia). Metastatic tumors can arise from a variety of primary tumor types, including, but not limited to, prostate, colon, lung, breast, and liver.
[0606] As used herein, the terms "cancer," "hyperproliferative," and "tumor" refer to cells capable of autonomous growth, i.e., an abnormal stage or condition characterized by rapid cell proliferation. Hyperproliferative and neoplastic disease states may be classified as pathological, i.e., those that characterize or constitute a disease state, or non-pathological, i.e., those that deviate from normal but are not associated with a disease state. The terms are used to include all types of cancer growth or oncogenic processes, metastatic tissues, or malignantly transformed cells, tissues, or organs, regardless of histopathological type or stage of invasiveness. "Pathological hyperproliferative" cells occur in disease states characterized by malignant tumor growth. An example of non-pathological hyperproliferative cells is the proliferation of cells associated with wound healing.
[0607] As used herein, the term "cancer" or "neoplasm" includes malignant tumors of various organ systems, such as lung, breast, thyroid, lymphatic, gastrointestinal and genitourinary tract, and adenocarcinomas, including colorectal cancer, renal cell carcinoma, prostate and / or testicular tumors, non-small cell carcinoma of the lung, cancer of the small intestine, and cancer of the esophagus.
[0608] As used herein, the term "carcinoma" is an art-recognized term and refers to a malignant tumor of epithelial or endocrine tissue, including respiratory carcinoma, gastrointestinal carcinoma, genitourinary carcinoma, testicular carcinoma, breast carcinoma, prostate carcinoma, endocrine carcinoma, and melanoma. In one embodiment, the disease is renal carcinoma or melanoma. Exemplary carcinomas include those forming in tissue of the cervix, lung, prostate, breast, head and neck, colon, and ovary. The term also includes carcinosarcomas, which include malignant tumors composed of carcinomatous and sarcomatous tissue. "Adenocarcinoma" refers to a carcinoma originating from glandular tissue or in which the tumor cells form distinguishable glandular structures.
[0609] As used herein, the term "sarcoma" is an art-recognized term that refers to a malignant tumor of intermediate lobe origin.
[0610] Further examples of proliferative disorders include hematopoietic neoplastic disorders. As used herein, the term "hematopoietic neoplastic disorder" includes diseases occurring in hyperplastic / neoplastic cells of hematopoietic origin, e.g., myeloid, lymphoid, or erythroid lineages, or their precursor cells. Preferably, such diseases occur in poorly differentiated acute leukemias, such as erythroid leukemia and acute adenytoblastic leukemia. Further examples of myeloid diseases include, but are not limited to, acute promyelocytic leukemia (APML), acute myeloid leukemia (AML), and chronic myeloid leukemia (CML) (Vaickus, L.

[0618] patient Suitable patients for the compositions and methods of the present invention include those suffering from, diagnosed with, or suspected of having a cell proliferative and / or differentiative disorder (e.g., cancer). Patients amenable to the techniques disclosed herein generally respond better to the methods and compositions herein, in part because the pharmaceutical compositions are allogeneic and do not target generally proliferating cells, but rather target cells identified by the antigen-binding domain. As a result, there are fewer off-target effects, and patients are more likely to complete treatment without harm from target-off effects.
[0619] In one embodiment, the therapeutic methods provided herein can be used to treat a subject (e.g., a human, monkey, dog, cat, mouse) diagnosed with or suspected of having a cell proliferative and / or differentiative disorder (e.g., cancer). In one embodiment, the subject is a mammal. In one embodiment, the subject is a human.
[0620] As used herein, a subject refers to a mammal, including, for example, a human.
[0621] In one embodiment, the mammal is selected from the group consisting of an armadillo, donkey, bat, bear, beaver, cat, chimpanzee, cow, coyote, deer, dog, dolphin, elephant, fox, panda, gibbon, giraffe, goat, gopher, hedgehog, hippopotamus, horse, humpback whale, jaguar, kangaroo, koala, leopard, deer, llama, lynx, mole, monkey, mouse, narwhal, orangutan, killer whale, otter, cow, pig, polar bear, hedgehog, puma, rabbit, raccoon dog, rat, rhinoceros, sheep, squirrel, tiger, sea elephant, weasel, wolf, zebra, goat, horse, and combinations thereof.
[0622] In one embodiment, the mammal is a human.
[0623] The subject, e.g., a human subject, may be a child between the ages of 0 and about 14. The subject may be an adolescent, e.g., between the ages of about 15 and about 24. The subject may be an adult, e.g., between the ages of about 25 and about 64. The subject may be an elderly person, e.g., 65 years of age or older.
[0624] In one embodiment, the subject may be a human exhibiting one or more symptoms associated with a cell proliferative and / or differentiative disorder, e.g., cancer, e.g., a tumor. The therapeutic methods provided herein can be used to treat various stages of cancer.

In one embodiment, the subject is in an early stage of cancer. In one embodiment, the subject is in an advanced stage of cancer. In various examples, the subject has stage 1, stage 2, stage 3, or stage 4 cancer. The therapeutic methods described herein can promote tumor reduction or regression, reduce or inhibit tumor growth or cancer cell proliferation, and / or induce, increase, or promote tumor cell death. In one embodiment, the subject is in cancer remission. The therapeutic methods described herein can prevent or delay cancer metastasis or recurrence.
[0625] In one embodiment, the subject has an Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, 2, 3, or 4 at the time of treatment.

[0627] As used herein, an "at-risk" individual refers to an individual who is at risk of developing a disease being treated (e.g., a cell proliferative and / or differentiative disorder such as cancer). Generally, an "at-risk" subject may or may not have detectable disease, and may or may not exhibit detectable disease prior to the treatment methods described herein. "At-risk" refers to an individual having one or more so-called risk factors, which are measurable parameters associated with the disease or disease onset and known to those skilled in the art. For example, an at-risk subject may have one or more risk factors, which are measurable parameters that correlate with the onset of cancer. Subjects with one or more such risk factors have a higher probability of developing cancer than individuals without such risk factors. Generally, risk factors can include, for example, age, sex, race, diet, history of previous disease, presence of precursor diseases, genetic factors, and environmental exposures. In one embodiment, a subject at risk of developing cancer includes, for example, a subject who has a relative who has experienced the disease or whose risk has been determined by analysis of genetic or biochemical markers.

[0724] dose An "effective amount" refers to an amount sufficient to achieve a beneficial or desired result. For example, a therapeutic dose is an amount capable of achieving a desired therapeutic effect. This amount may be the same as or different from a prophylactically effective amount, which is an amount necessary to prevent the onset of a disease or disease symptom. An effective amount can be administered in one or more administrations, dosages, or doses. The therapeutically effective amount (i.e., effective dosage) will vary depending on the therapeutic compound selected. The composition can be administered one or more times per week, including once or more times per day to once every other day. One of skill in the art will recognize that certain factors, including, but not limited to, the severity of the disease or disorder, previous treatments, the subject's general health and / or age, and other existing illnesses, can affect the dosage and timing required to effectively treat a subject. Additionally, treating a subject with a therapeutically effective amount of a therapeutic composition described herein can include a single treatment or a series of consecutive treatments.
[0725] The dosage, toxicity, and therapeutic efficacy of therapeutic compounds can be determined by standard control procedures in cell cultures or experimental animals, e.g., to determine the LD50 (the dose that is lethal to 50% of a population) and the ED50 (the dose that is therapeutically effective in 50% of a population). The dose ratio between toxicity and therapeutic effect is referred to as the therapeutic index and can be expressed as the ratio LD50 / ED50. Compositions that exhibit high therapeutic indices are preferred. Compositions that exhibit toxic side effects can be used, but care must be taken to design a delivery system that targets such compositions to infected tissue sites in order to minimize potential damage to uninfected cells and reduce side effects.
[0726] Data obtained from cell culture assays and animal studies can be used to formulate various dosages for use in humans. The dosage of such compounds can lie within a circulating concentration range that includes the ED50 with little or no toxicity. The dosage within this range may vary depending on the dosage form and route of administration used. For all compounds used in the methods of the present invention, the therapeutically effective amount can be initially estimated from cell culture assays. Doses can be formulated in animal models to achieve a circulating plasma concentration range that includes the IC50 (i.e., the concentration of the test substance that achieves half-maximal inhibition of symptoms) determined in cell culture. Such information can be used to more accurately determine useful doses in humans. Plasma concentrations can be measured, for example, by high-performance liquid chromatography.
