Abstract
Description
[Technical Field]
[0001] The present disclosure relates to pharmaceutical compositions comprising engineered natural killer (NK) cells and antigen-specific T cells. Methods for culturing the engineered NK cells and antigen-specific T cells are also provided. [Background technology]
[0002] Immune surveillance plays a key role in cancer and represents a very attractive therapeutic approach, especially considering the many shortcomings of traditional surgery, radiation, and chemotherapy in cancer management.
[0003] The human body's first line of defense against cancer is CD3 - CD14 - CD19 - CD56 + CD16 + NGK2D + CD11c dim HLA-DR - CD86 - CD83 - The phenotype of NK cells is that they are natural killer (NK) cells. NK cells are cytotoxic lymphocytes that actively scan the body for abnormal cells and destroy them before they can develop into actual cancer cells. As NK cells patrol the body, they interact with many types of cells using their array of activating and inhibitory surface receptors. Most cancer cells engage with NK cell activating receptors, which triggers their natural killing response.
[0004] US Patent Application Publication No. 20210260115 discloses modified NK cells with both NK cell and dendritic cell functions, as well as a method for culturing the same. When the modified NK cells are administered to a subject with cancer, the modified NK cells kill tumor cells in vivo, present tumor-associated antigens (TAA) to naive T cells, and induce a T cell response (Figure 1). However, prior to the culturing process, CD3 - CD14 - CD19 -A step of negative selection of mononuclear cells is required, which leads to problems of high cost and complicated manufacturing process due to low cell yield. Nevertheless, there is also uncertainty about the efficacy of TAA-specific CD8 T cells induced by engineered NK cells in vivo. [Prior art documents] [Patent documents]

[0020] Illustrative embodiments of the present application are described in detail below with reference to the following drawings: [Brief explanation of the drawings]
[0021] [Figure 1]Figure 1 illustrates that tumor-associated antigens (TAA) were presented to CD8 T cells by engineered NK cells in vivo, as in the prior art, U.S. Patent Application Publication No. 20210260115. Adoptive cell transfer of the engineered NK cells mediates NK-dependent cytotoxicity to kill tumor cells, resulting in the release of tumor-associated antigens (TAA). Simultaneously, the engineered NK cells also acquire tumor antigens and present the full spectrum of TAAs to CD8 T cells, resulting in the induction of multi-epitope tumor-specific CD8 T cell proliferation and activation. These tumor-specific T cells can then migrate to the tumor bed site in vivo to initiate long-term anti-tumor T cell responses. [Figure 2] Figure 2 illustrates that tumor-associated antigens (TAA) are presented to CD8+ T cells by engineered NK cells in vivo, and the antigen-specific CD8+ T cells are expanded in vitro and adoptively transferred back into the patient to be treated. The pharmaceutical composition comprises engineered NK cells and tumor-specific CD8+ T cells, i.e., antigen-specific T cells. The engineered NK cells can activate tumor-specific CD8+ T cells in vivo through antigen-presenting cell activity, which can be further expanded to produce engineered NK cells. Compared to that described in Figure 1 , the adoptive cell transfer of the present disclosure retains the original properties of the engineered NK cells to drive multi-epitope tumor-specific CD8+ T cell activation. In addition, it also delivers robust anti-tumor cytotoxic T lymphocyte (CTL) cell responses through the engineered NK cell-driven CD8+ T cells expanded in vitro. Repeated adoptive cell transfer of this novel pharmaceutical composition can deliver advanced anti-tumor immune responses. [Figure 3] FIG. 3 illustrates the absolute cell numbers of modified NK cells cultured according to prior art methods and the methods of the present disclosure. [Figure 4] FIG. 4 illustrates that the methods of the present disclosure significantly expanded CD8 T cell populations compared to fresh peripheral blood mononuclear cells (PBMCs). [Figure 5A] FIG. 5A illustrates that the methods of the present disclosure significantly expanded the CD8 T cell population and increased the CD8 to CD4 ratio. [Figure 5B] FIG. 5B illustrates that the methods of the present disclosure significantly expanded the CD8 T cell population and increased the CD8 to CD4 ratio. [Figure 6] FIG. 6 illustrates that the methods of the present disclosure induced antigen (Ag)-specific activation-inducible marker (AIM)+ CD8 T cells.

[0045] In one embodiment, the expression level or surface density of a cell surface antigen is quantified by exposing the engineered NK cells or antigen-specific T cells to a specific fluorochrome-tagged anti-human monoclonal antibody (e.g., CD86-PE (Beckman Coulter; Cat. No. IM2729U) or anti-human CD83-PE-Cy5 (BioLegend; Cat. No. 305310)), followed by sorting the engineered NK cells or antigen-specific T cells using a flow cytometer (e.g., Navios, commercially available from Beckman Coulter, Inc., USA).
[0046] The engineered NK cells or antigen-specific T cells can be generated from a single individual, for example, autologous or allogeneic.
[0047] Pharmaceutical Composition In one embodiment, the present application provides a pharmaceutical composition comprising the modified NK cells and antigen-specific T cells described herein and a pharmaceutically acceptable carrier or excipient. In one embodiment, the modified NK cells and antigen-specific T cells are produced together from mononuclear cells, e.g., peripheral blood mononuclear cells (PBMCs).
[0048] The present application also provides a method for inhibiting cancer cells by administering the pharmaceutical composition to a subject in need thereof in an amount effective to inhibit cancer cells. Without being bound by any particular theory, it is believed that the pharmaceutical composition inhibits cancer cells by antigen-specific T cells and engineered NK cells having one or more of the following functions: enhancing cytotoxicity, stimulating cancer-specific T lymphocyte proliferation, or IFN-γ secretion.
[0049] Routes of administration of the pharmaceutical compositions or modified NK cells include, but are not limited to, intravenous, intramuscular, subcutaneous, oral, topical, intradermal, transdermal, subcutaneous, parenteral, rectal, spinal, or epidermal administration. In one embodiment, the modified NK cells are administered by intravenous injection or infusion.
[0050] The pharmaceutical compositions of the present application may be prepared as injectables, either as liquid solutions or suspensions, or as solid forms suitable for solution in, or suspension in, liquid vehicles prior to injection.
[0051] The modified NK cells and antigen-specific T cells are formulated into pharmaceutical compositions for delivery to mammalian subjects. The pharmaceutical compositions are administered alone and / or mixed with a pharmaceutically acceptable vehicle, excipient, or carrier. Suitable vehicles include, for example, saline (e.g., normal saline), dextrose, glycerol, platelet-rich plasma (PRP), and the like, and combinations thereof. In addition, the vehicle may contain minor amounts of auxiliary substances, such as wetting or emulsifying agents, pH buffering agents, or adjuvants. The pharmaceutically acceptable carrier may contain a physiologically acceptable compound that acts, for example, to stabilize, or increase or decrease the absorption or clearance rate of the pharmaceutical composition of the present application. Physiologically acceptable compounds may include, for example, carbohydrates such as glucose, sucrose, or dextran; antioxidants such as ascorbic acid or glutathione; chelating agents; low-molecular-weight proteins; surfactants; liposome carriers; or excipients; or other stabilizers and / or buffers. Other physiologically acceptable compounds include wetting agents, emulsifying agents, dispersing agents, or preservatives. See, e.g., Remington's Pharmaceutical Sciences, 21st Edition, Mack Publishing Company, Easton, Pa. ("Remington's"). The pharmaceutical compositions of the present application may also include accessory substances, such as pharmacological agents, cytokines, or other biological response modifiers.
[0052] Actual methods for preparing such dosage forms will be known or apparent to those skilled in the art. See, e.g., Remington's Pharmaceutical Sciences, Mack Publishing Company, Easton, Pennsylvania, 21st Edition.
[0053] Whether the pharmaceutical composition is used for prophylactic or curative purposes, etc., it can be administered as a single dose treatment or a multiple dose treatment on a schedule and for a predetermined period of time appropriate to the age, weight, and condition of the subject, the particular composition used, and the route of administration. For example, in one embodiment, the pharmaceutical composition according to the present application is administered once a month, twice a month, three times a month, every other week (qow), once a week (qw), twice a week (biw), three times a week (tiw), four times a week (qiw), five times a week, six times a week, every other day (qod), daily (qd), twice a day (bid), three times a day (tid), or four times a day (qid).
[0054] The duration of treatment with a pharmaceutical composition according to the present application, e.g., the period over which the pharmaceutical composition is administered, can vary depending on any of a variety of factors, e.g., the subject's response, etc. For example, the pharmaceutical composition can be administered for a period ranging from about 1 second or more to 1 minute or more, from 1 hour or more to 1 day to about 1 week, from about 2 weeks to about 4 weeks, from about 1 month to about 2 months, from about 2 months to about 4 months, from about 4 months to about 6 months, from about 6 months to about 8 months, from about 8 months to about 1 year, from about 1 year to about 2 years, or from about 2 years to about 4 years, or for a longer period.
[0055] For ease of administration and uniformity of dosage, it is advantageous to formulate parenteral pharmaceutical compositions in dosage unit form. As used herein, dosage unit form refers to physically discrete units suited as unitary dosages for the subject to be treated, each unit containing a predetermined quantity of modified NK cells and antigen-specific T cells calculated to produce the desired therapeutic effect in association with the necessary pharmaceutical carrier.
[0056] The data obtained from cell culture assays and animal studies can be used to formulate a range of dosages for use in humans.

[0057] The pharmaceutical compositions are formulated to contain effective amounts of modified NK cells and antigen-specific T cells, where the amounts depend on the animal being treated and the condition being treated. The specific dose level for any particular subject will depend on a variety of factors, including the activity of the specific modified NK cells and antigen-specific T cells, age, body weight, general health, sex, diet, number of doses, route of administration, and rate of excretion, drug combination, and the severity of the particular disease being treated. An exemplary, non-limiting range for a therapeutically or prophylactically effective amount of the pharmaceutical compositions of the present application is at least about 1 x 10 per dose. 3 Approximately 1 x 10 cells per dose 9 The dose is, but is not limited to, 1 x 10 cells per dose. 4 , 1×10 5 , 1×10 6 , 1×10 7 , 1×10 8 or 1 x 10 9 Other dosages, including individual cells, are possible.
[0058] The pharmaceutical composition can be administered alone or in combination with another therapeutic agent, for example, chemotherapy, radiation therapy or targeted therapy, or a cancer vaccine.
[0059] Methods for producing pharmaceutical compositions In one embodiment, a method for producing modified NK cells and antigen-specific T cells is illustrated in Figure 12. Briefly, the method includes at least the steps of obtaining mononuclear cells; contacting the mononuclear cells with a first culture medium comprising IL-15, IL-12, and IL-18 for about 1-6 days to obtain a cultured cell population; and, after contact with the first culture medium, contacting the cultured cell population with a second culture medium comprising IL-15 and IL-12 for about 1-6 days, wherein the second culture medium comprises CD3 - CD19 - CD14 - No negative selection is performed on the mononuclear cells prior to the contacting step.
[0060] Preferably, the mononuclear cells used herein for the selection or production of modified NK cells and antigen-specific T cells are CD3+ mononuclear cells as the initial cell population for expansion culture. - CD14 - CD19 - Negative selection of cells has not been performed; they are mononuclear cells.
[0061] One embodiment of the present disclosure provides a method for identifying early cells from a sample that does not include removing one or more of the following cell surface antigens from mononuclear cells in the sample: CD3, CD14, or CD19.
[0062] The duration of culture of a composition comprising IL-12 can be important for the function of modified NK cells. In embodiments, mononuclear cells can be cultured with IL-12, e.g., human IL-12, for 1 to 12 days, preferably 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 days, to generate modified NK cells. In embodiments, mononuclear cells cultured with IL-12 for 3, 6, 9, or 12 days produce modified NK cells with similar cell yields and phenotypic patterns. In another embodiment, prolonged exposure to IL-12, e.g., 12 days, increased the cytotoxicity and antigen-presenting cell activity of the cultured cells compared to cells exposed to IL-12 for a shorter period of time, e.g., 9 days.
[0063] In one embodiment, the composition for culturing cells further comprises IL-18. In one embodiment, the effective concentration of IL-18 is about 1 to 300 ng / mL, e.g., 50, 100, 150, 200, 250, 300 ng / mL, etc. In another embodiment, the effective concentration of IL-18 is about 10 to about 250 ng / mL, or any value or range of values therebetween in increments of 10 ng / mL (e.g., about 30 ng / mL, about 220 ng / mL, etc.).
[0064] In another embodiment, IL-18 has a reduced effect on the phenotypic pattern and functional activity of modified NK cells. Longer-term IL-18 exposure may have adverse effects on cell size, phenotype, and functional activity. In an embodiment, mononuclear cells can be cultured with IL-18, e.g., human IL-18, for 1 to 12 days, preferably 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 days, to generate modified NK cells. In an embodiment, mononuclear cells cultured with IL-18 for 3, 6, 9, or 12 days produce modified NK cells with various phenotypes. In another embodiment, sufficient exposure to IL-18, e.g., 6 days, may have adverse effects on the cell size, phenotype, and function of modified NK cells compared to cells exposed to IL-18 for a shorter period of time, e.g., 6 days.
[0065] In one embodiment, mononuclear cells are contacted with a culture composition comprising IL-18, IL-15, and / or IL-12. In another embodiment, mononuclear cells can be mixed with a composition consisting essentially of hematopoietic cell medium (e.g., X-vivo 20), IL-18, IL-15, IL-12, and serum proteins (e.g., human platelet lysate). In yet another embodiment, mononuclear cells can be mixed with a composition consisting essentially of X-vivo 20, IL-18, IL-15, IL-12, and human platelet lysate.
[0066] In another embodiment, the composition further comprises a hematopoietic cell culture medium, non-limiting examples of which include X-vivo 10, X-vivo 15, X-vivo 20 (commercially available from Lonza, Switzerland), and AIM-V (commercially available from ThermoFisher Scientific, USA).
[0067] In yet another embodiment, the composition further comprises a serum protein, e.g., human platelet lysate. In this application, a "serum protein" is a protein present in blood or plasma that performs many different functions, including regulating transport and cellular activity. Non-limiting examples of serum proteins include enzymes, complement components, protease inhibitors, kinin precursors, serum albumin, globulins, and fibrinogen.
[0068] Non-limiting examples of compositions for culturing cells include: (a) hematopoietic cell medium + IL-15 + IL-18; (b) hematopoietic cell medium + IL-15 + IL-18; (c) hematopoietic cell medium + IL-15 + IL-12 + IL-18; (d) X-vivo 20 + IL-15 + IL-18; (e) X-vivo 20 + IL-12 + IL-18; (f) X-vivo 20+IL-15+IL-12+IL-18;(g)AIM-V+IL-15+IL-18;(h)AIM-V+IL-12+IL-18;(i)AIM-V+IL-15+IL-12+IL-18;(j)Hematopoietic cells Medium+IL-15+IL-18+serum protein;(k)Hematopoietic cell medium+IL-12+IL-18+serum protein;(l)Hematopoietic cell medium+IL-15+IL-12+IL-18+serum protein;(m)X-vivo 20+IL-15+IL-18+serum protein;(n)X-vivo 20+IL-12+IL-18+serum protein;(o)X-vivo (p) AIM-V + IL-15 + IL-12 + IL-18 + serum protein; (q) AIM-V + IL-12 + IL-18 + serum protein; and (r) AIM-V + IL-15 + IL-12 + IL-18 + serum protein.

Other assays for cell proliferation, such as clonogenic assays, metabolic assays, and direct proliferation assays, are well known in the art.
[0071] Exemplary, non-limiting ranges for the contact time between the mononuclear cells and the culture medium are about 1 minute to about 1 hour, about 1 hour to about 24 hours, about 1 day to about 3 days, about 1 day to about 6 days, about 1 day to about 9 days, about 1 day to about 12 days, about 3 days to about 6 days, about 3 days to about 9 days, about 3 days to about 12 days, about 6 days to about 9 days, about 6 days to about 12 days, or at least 1 day. In one embodiment, the contact time is about 3 days. In another embodiment, the contact time is about 6 days.
[0072] In one embodiment, the mononuclear cells are contacted with a first culture medium comprising IL-15, IL-12, and IL-18; and subsequently with a second culture medium comprising IL-15 and IL-12. In another embodiment, the first and second culture media further comprise a hematopoietic cell medium such as AIM-V or X-vivo and / or a serum protein such as human platelet lysate.

[0077] Example 1 Preparation of initial cells 40 mL of peripheral blood was collected from healthy volunteers into vacuum tubes containing K2EDTA. The blood sample was mixed with an equal volume of pre-warmed phosphate-buffered saline (PBS) (Biological Industries, Israel). 40 mL of diluted peripheral blood aliquot was placed in a 50 mL centrifuge tube, and 10 mL of pre-warmed Ficoll-Paque™ PREMIUM was added. The centrifuge tube was centrifuged at 2000 rpm at room temperature for 30 minutes. Mononuclear cells at the interface layer were collected and washed once with PBS. The cell pellet was collected in 10 mL of PBS. 6 Resuspended to a density of 100 cells / 100 mL MACS buffer.
[0078] Example 2 Cultivation of engineered NK cells and antigen-specific T cells Mononuclear cells from Example 1 were cultured for 12 days in AIM-V medium containing 4% HPL, hIL-15 (days 0, 3, 6, 9), 3 ng / ml hIL-12 (days 0, 3, 6, 9), and hIL-18 (days 0, 3, 6). Total cell count and viability were determined by trypan blue exclusion. Absolute cell numbers were calculated using the following formula:
[0079] Results: As shown in Table 3 and Figure 3, the enrichment step in the prior art significantly reduced the number of initial cells for production. Although the purity of the modified NK cells was higher, the absolute cell number of the modified NK cells of the prior art was only one-fifth that of the modified NK cells of the present disclosure. On the other hand, with the method of the present disclosure, production significantly expanded the CD8 T cell population, as shown in Figures 4, 5A, and 5B.

The cytotoxicity of the modified NK cells and antigen-specific T cells was evaluated using the PanToxilux kit (OncoImmunin, Inc.). Human ovarian epithelial carcinoma (EOC) cells served as target cells and were stained with TFL-4 at an optimal concentration for 50 minutes. TFL-4-labeled target cells and modified NK cells or antigen-specific T cells were co-incubated with a caspase substrate at 37°C for 60 minutes. The cells were harvested and stained with TFL-4. + substrate + Cell death was analyzed by determining the signal of β-glucan by flow cytometry. Statistical analysis was performed using Student's t-test, and results were considered significant if P<0.05. ns: not significant. *: P<0.05, **: P<0.01, ***: P<0.001.
[0086] Results: As shown in Figures 10 and 11, the percentage of caspase-positive target cells (for the modified NK cells alone or the Ag-specific T cells alone) was 9.63% and 10.14%, respectively, while the percentage of caspase-positive target cells (for the pharmaceutical composition of the present disclosure) was 12.45%, an increase of at least 22.7% compared to the modified NK cells alone or the Ag-specific T cells alone. This result indicates that the pharmaceutical composition of the present disclosure, generated from a patient, exhibited tumoricidal activity against primary tumor cells derived from the same patient.
