[Background technology]
[0002] The treatment of large, refractory cancers using adoptive transfer of tumor-infiltrating lymphocytes (TILs) is a powerful treatment option for patients with a poor prognosis. (Gattinoni, et al., Nat. Rev. Immunol. 2006, 6, 383-393). A large number of TILs are required for successful immunotherapy, and commercialization necessitates a robust and reliable process. This has been difficult to achieve due to technical, logistical, and regulatory issues related to cell proliferation. IL-2-based TIL proliferation and subsequent "rapid proliferation processes" (REP) have become the recommended method for TIL proliferation due to their speed and efficiency. Dudley, et al., Science 2002, 298, 850-54; Dudley, et al., J. Clin. Oncol. 2005, 23, 2346-57; Dudley, et al., J. Clin. Oncol. 2008, 26, 5233-39; Riddell, et al., Science 1992, 257, 238-41; Dudley, et al., J. Immunother. 2003, 26, 332-42. REP can increase TILs 1,000-fold in 14 days, but often requires a large excess (e.g., 200-fold) of irradiated allogeneic peripheral blood mononuclear cells (PBMCs, also known as mononuclear cells (MNCs)) and anti-CD3 antibody (OKT3) from multiple donors as feeder cells, as well as high doses of IL-2. Dudley, et al., J. Immunother. 2003, 26, 332-42. TILs subjected to the REP procedure produced effective adoptive cell therapy after host immunosuppression in melanoma patients. Current fluid tolerance parameters depend on the compositional readings of the TILs (e.g., CD28, CD8, or CD4 positive) and the proliferation rate and viability of the REP product.
[0003] Current TIL manufacturing processes are limited by length, cost, sterility issues, and other factors described herein. There is an urgent need to provide TIL manufacturing processes and therapies based on such processes that improve cost-effectiveness and scalability in manufacturing and feature more potent anti-cancer phenotypes in TIL preparations produced for the treatment of human patients in multiple clinical centers. The present invention satisfies this need by providing a novel TIL proliferation process that includes antigen-presenting feeder cells from the initiation of proliferation to prime TILs for proliferation, rather than the conventional pre-REP proliferation process, thereby enabling a reduction in the overall time of the proliferation process.

[0650] The term "in vivo" refers to events that occur within the subject's body.
[0651] The term "in vitro" refers to events that occur outside the body of the subject. In vitro assays encompass cell-based assays that use living or dead cells, and may also include cell-free assays that do not use intact cells.
[0652] The term "ex vivo" refers to events involving the performance of treatment or procedures on cells, tissues, and / or organs removed from a subject's body. Where appropriate, cells, tissues, and / or organs may be returned to the subject's body by surgical or therapeutic means.
[0653] The term "rapid growth" means an increase in the number of antigen-specific TILs of at least approximately 3 times (or 4 times, 5 times, 6 times, 7 times, 8 times, or 9 times) over one week, more preferably at least approximately 10 times (or 20 times, 30 times, 40 times, 50 times, 60 times, 70 times, 80 times, or 90 times) over one week, or most preferably at least approximately 100 times over one week. An overview of some rapid growth protocols is provided below.
[0654] In this specification, "tumor-infiltrating lymphocytes" or "TILs" refers to the initial population of cells obtained as leukocytes that have left the bloodstream and migrated into the tumor. TILs include CD8 + Cytotoxic T cells (lymphocytes), Th1 and Th17CD4 + TILs include, but are not limited to, T cells, natural killer cells, dendritic cells, and M1 macrophages. TILs include both primary and secondary TILs. "Primary TILs" are those obtained from a patient's tissue sample as outlined herein (and may be referred to as "freshly obtained" or "freshly isolated"), and "secondary TILs" are any proliferation or augmented TIL cell populations considered herein, including, but not limited to, bulk TILs and augmented TILs ("REP TILs" or "post-REP TILs"). TIL cell populations may include genetically modified TILs.
[0655] In this specification, "cell population" (including TILs) means a large number of cells that share common traits. Generally, a population is typically 1 × 10⁶ in number. 6 ~1 × 10 10 This ranges, and different TIL populations consist of different numbers. For example, the initial growth of primary TILs in the presence of IL-2 is approximately 1 × 10⁻⁶. 8This results in a bulk TIL population of cells. REP proliferation is generally 1.5 × 10⁶ for injection. 9 ~1.5×10 10 This is done to provide a population of cells. In some embodiments, 2.3 × 10 10 ~13.7×10 10 REP proliferation is performed to provide a population.
[0656] In this specification, “cryopreserved TIL” means primary, bulk, or regenerated (REP TIL) tissue that has been processed and stored at a temperature in the range of approximately -150°C to -60°C. General methods of cryopreservation are also described elsewhere in this specification, including in the examples. For clarity, “cryopreserved TIL” can be distinguished from frozen tissue samples that can be used as a source for primary TIL.
[0657] In this specification, “thawed cryopreserved TILs” means a population of TILs that have been previously cryopreserved and then treated to return to room temperature or above, including but not limited to cell culture temperature or a temperature at which the TILs may be administered to a patient.
[0658] TILs can generally be defined biochemically using cell surface markers or functionally by their ability to infiltrate tumors and influence treatment. TILs can generally be classified by expressing one or more of the following biomarkers: CD4, CD8, TCRαβ, CD27, CD28, CD56, CCR7, CD45Ra, CD95, PD-1, and CD25. In addition, and alternatively, TILs can be functionally defined by their ability to infiltrate solid tumors upon reintroduction into a patient. TILs can be further characterized by potency; for example, a TIL may be considered potent if the release of interferon (IFN) is greater than approximately 50 pg / mL, 100 pg / mL, 150 pg / mL, or 200 pg / mL. For example, a TIL may be considered effective if the interferon (IFNγ) release is greater than approximately 50 pg / mL, 100 pg / mL, 150 pg / mL, or 200 pg / mL, 300 pg / mL, 400 pg / mL, 500 pg / mL, 600 pg / mL, 700 pg / mL, 800 pg / mL, 900 pg / mL, or 1000 pg / mL.

CD8+ effector memory T cells possess large amounts of perforin.
[0662] A "closed system" refers to a system that is closed off from the external environment. Any closed system suitable for cell culture can be used in the method of the present invention. Closed systems include, but are not limited to, closed G-containers. Once tumor segments are added to the closed system, the system is not opened to the external environment until the TIL is ready to be administered to the patient.
[0663] The terms “fragmentation,” “fragment,” and “fragmented” as used herein to describe a process for destroying a tumor include mechanical fragmentation methods such as crushing, slicing, splitting, and cutting tumor tissue, as well as any other method for destroying the physical structure of tumor tissue.
[0664] The term "fine-needle aspiration" or FNA refers to a type of biopsy procedure that can be used in sampling or diagnostic procedures, including tumor sampling, which involves taking a sample but not removing or excising the tumor. In fine-needle aspiration, as described herein, a hollow needle, e.g., 25-18 gauge, is inserted into the tumor or an area containing a tumor to obtain fluid and cells (including tissue) for further analysis or growth. With FNA, cells are extracted without preserving the histological structure of the tissue cells. FNA may include tissue-infiltrated lesions (TILs). In some cases, fine-needle aspiration cytology is performed using an ultrasound-guided fine-needle aspiration biopsy needle. FNA needles are commercially available from Becton Dickinson, Covidien, and others.
[0665] The term “core biopsy” or “core needle biopsy” refers to a type of biopsy procedure that can be used in sampling or diagnostic procedures, including tumor sampling, which involves taking a sample but not removing or excising the tumor. In fine-needle aspiration, as described herein, a hollow needle, e.g., 16-11 gauge, is inserted into the tumor or an area containing a tumor to obtain fluid and cells (including tissue) for further analysis or growth. In core biopsy, the larger needle size compared to FNA allows for the extraction of cells with some degree of histological structure preserved. Core biopsy needles are generally of a gauge size that can preserve at least some of the tumor's tissue structure. Core biopsies may include TILs. In some cases, core needle biopsies are performed using biopsy instruments, vacuum-assisted core needle biopsy instruments, stereotactic core needle biopsy instruments, ultrasound-guided core needle biopsy instruments, and MRI-guided core needle biopsy instruments, which are commercially available from companies such as Bard Medical and Becton Dickinson.
[0666] The terms "peripheral blood mononuclear cells" and "PBMCs" refer to peripheral blood cells with round nuclei, including lymphocytes (T cells, B cells, NK cells) and monocytes.

[0667] The terms “peripheral blood lymphocytes” and “PBL” refer to T cells proliferated from peripheral blood. In some embodiments, PBLs are isolated from whole blood or apheresis products from a donor. In some embodiments, PBLs are isolated from whole blood or apheresis products from a donor by positive or negative selection of T cell phenotypes, such as CD3+CD45+ T cell phenotypes.
[0668] The term "anti-CD3 antibody" refers to an antibody or its variant, such as a monoclonal antibody, including human, humanized, chimeric, or mouse antibodies against the CD3 receptor in the T cell antigen receptor of mature T cells. Anti-CD3 antibodies include OKT-3, also known as muromonab. Anti-CD3 antibodies also include the UHCT1 clone, also known as T3 and CD3ε. Other anti-CD3 antibodies include, for example, otelixizumab, teprizumab, and bicilizumab.
[0669] The term "OKT-3" (also referred to herein as "OKT3") refers to monoclonal antibodies or biosimilars or variants thereof, including human, humanized, chimeric, or mouse antibodies against the CD3 receptor, the T cell antigen receptor of mature T cells, and includes commercially available forms such as OKT-3 (30 ng / mL, MACS GMP CD3pure, Miltenyi Biotech, Inc., San Diego, CA, USA) and muromonab or its variants, conservative amino acid substitutions, glycoforms, or biosimilars thereof.

In some embodiments, after non-myeloablative chemotherapy and TIL infusion according to the present invention (day 0), the patient receives intravenous infusion of IL-2 at 720,000 IU / kg every 8 hours until it reaches a physiologically acceptable level.
[0689] Experimental results indicate that lymphatic depletion prior to adoptive transfer of tumor-specific T lymphocytes plays a crucial role in enhancing therapeutic efficacy by eliminating regulatory T cells and competing elements of the immune system ("cytokine sinks"). Therefore, some embodiments of the present invention utilize a lymphatic depletion step (also referred to as "immunosuppressive conditioning") in the patient before introducing the rTIL of the present invention.
[0690] As used herein, the terms “simultaneous administration,” “administered simultaneously,” “administered in combination,” “administered in combination,” “simultaneous,” and “concurren” encompass the administration of two or more active pharmaceutical ingredients (in preferred embodiments of the present invention, for example, at least one potassium channel agonist combined with multiple TILs) to a subject, so that the active pharmaceutical ingredients and / or their metabolites are present in the subject simultaneously. Simultaneous administration includes simultaneous administration in separate compositions, administration of separate compositions at different time points, or administration in a single composition containing two or more active pharmaceutical ingredients. Simultaneous administration in separate compositions and administration in a composition containing both drugs are preferred.
[0691] The terms “effective dose” or “therapeutic effective dose” refer to the amount of a compound or combination of compounds described herein that is sufficient to achieve an intended application, including but not limited to the treatment of a disease. The therapeutic effective dose may vary depending on the intended application (in vitro or in vivo), the subject and disease state being treated (e.g., the subject’s weight, age, and sex), the severity of the disease state, or the method of administration. The term also applies to doses that elicit a specific response in target cells (e.g., reduced platelet adhesion and / or cell migration). A specific dose may vary depending on the specific compound selected, the dosing plan to be followed, whether the compound is administered in combination with other compounds, the timing of administration, the tissue to which it is administered, and the physical delivery system through which the compound is carried.
[0692] As used herein, terms such as “treatment,” “to treat,” and “to cure” refer to obtaining a desired pharmacological and / or physiological effect. This effect may be prophylactic in that it completely or partially prevents the disease or symptoms thereof, and / or therapeutic in that it partially or completely cures the disease and / or any side effects resulting from it. As used herein, “treatment” encompasses any treatment of a disease in mammals, particularly humans, and includes (a) preventing the onset of the disease in subjects who are susceptible to or at risk of developing the disease but have not yet been diagnosed with it; (b) inhibiting the disease, i.e., preventing its manifestation or progression; and (c) mitigating the disease, i.e., causing its regression and / or reduction. “Treatment” also means the delivery of a drug to provide a pharmacological effect even in the absence of a disease or condition. For example, “treatment” includes the delivery of a composition that can induce an immune response or provide immunity in the absence of a disease condition, for example, in the case of a vaccine.
[0693] When used in part with nucleic acids or proteins, the term “heterogeneous” indicates that the nucleic acid or protein contains two or more sequences or subsequences that are not found in the same relationship to one another. For example, typically, nucleic acids are recombinantly produced to have two or more sequences from unrelated genes arranged to create a new functional nucleic acid, e.g., a promoter from one source and a coding region from the other source, or coding regions from different sources. Similarly, heterogeneous proteins indicate that the protein contains two or more subsequences that are not found in the same relationship to one another in nature (e.g., fusion proteins).
[0694] In the context of two or more nucleic acids or polypeptides, the terms “sequence identity,” “percent identity,” and “sequence percent identity” (or their synonyms, e.g., “99% identity”) refer to two or more sequences or subsequences that, when compared and aligned (with gaps introduced as necessary) to obtain the greatest possible match, are identical or have an explicit percentage of the same nucleotide or amino acid residues, without considering conserved amino acid substitutions as part of sequence identity. Percent identity can be measured using sequence comparison software or algorithms, or by visual inspection. Various algorithms and software that can be used to obtain alignment of amino acid or nucleotide sequences are known in the art. Suitable programs for determining percent sequence identity include, for example, the BLAST suite of programs available from the BLAST website of the U.S. government's National Center for Biotechnology Information. Comparison between two sequences can be performed using either the BLASTN or BLASTP algorithm. BLASTN is used for comparing nucleic acid sequences, and BLASTP is used for comparing amino acid sequences. ALIGN, ALIGN-2 (Genentech, South San Francisco, California), or MegAlign, available from DNASTAR, are additional publicly available software programs that can be used to align sequences. Those skilled in the art can determine appropriate parameters for maximum alignment using specific alignment software. In certain embodiments, the default parameters of the alignment software are used.
[0695] As used herein, the term “variant” includes, but is not limited to, a protein, antibody, or fusion protein having an amino acid sequence different from that of a reference antibody, antibody, or fusion protein due to one or more substitutions, deletions, and / or additions within or adjacent to the amino acid sequence of the reference antibody, antibody, or fusion protein. A variant may have one or more conservative substitutions in its amino acid sequence compared to that of the reference antibody. Conservative substitutions may include, for example, substitutions of similarly charged or uncharged amino acids. A variant retains the ability to specifically bind to the antigen of the reference antibody, protein, or fusion protein. The term “variant” also includes pegylated antibodies or proteins.
[0696] In this specification, "tumor-infiltrating lymphocytes" or "TILs" refers to the initial population of cells obtained as leukocytes that have left the bloodstream and migrated into the tumor. TILs include CD8 + Cytotoxic T cells (lymphocytes), Th1 and Th17CD4 + TILs include, but are not limited to, T cells, natural killer cells, dendritic cells, and M1 macrophages. TILs include both primary and secondary TILs. "Primary TILs" are obtained from a patient's tissue sample as outlined herein (and may be referred to as "freshly obtained" or "freshly isolated"), and "secondary TILs" are any proliferation or proliferationd TIL cell populations as considered herein, and include, but are not limited to, bulk TILs and proliferationd TILs ("REP TILs"), as well as "reREP TILs," as considered herein. reREP TILs may include, for example, a second proliferation TIL or a second additional proliferation TIL (e.g., a TIL referred to as a reREP TIL, as described in step D of Figure 1).
[0697] TILs can generally be defined biochemically using cell surface markers or functionally by their ability to infiltrate tumors and influence treatment. TILs can generally be classified by expressing one or more of the following biomarkers: CD4, CD8, TCRαβ, CD27, CD28, CD56, CCR7, CD45Ra, CD95, PD-1, and CD25. In addition, or alternatively, TILs can be functionally defined by their ability to infiltrate solid tumors upon reintroduction into a patient. TILs can be further characterized by potency; for example, a TIL may be considered potent if the release of interferon (IFN) is greater than approximately 50 pg / mL, 100 pg / mL, 150 pg / mL, or 200 pg / mL. For example, a TIL may be considered effective if the interferon (IFNγ) release is approximately 50 pg / mL, greater than approximately 100 pg / mL, greater than approximately 150 pg / mL, or greater than approximately 200 pg / mL, greater than approximately 300 pg / mL, greater than approximately 400 pg / mL, greater than approximately 500 pg / mL, greater than approximately 600 pg / mL, greater than approximately 700 pg / mL, greater than approximately 800 pg / mL, greater than approximately 900 pg / mL, or greater than approximately 1000 pg / mL.
[0698] The terms “pharmaceutically acceptable carrier” or “pharmaceutically acceptable excipient” are intended to include any and all solvents, dispersions, coatings, antibacterial and antifungal agents, isotonic and absorption retardants, and inactive components. The use of such pharmaceutically acceptable carriers or pharmaceutically acceptable excipients with active pharmaceutical ingredients is well known in the art. Unless a conventional pharmaceutically acceptable carrier or pharmaceutically acceptable excipient is incompatible with the active pharmaceutical ingredient, its use in the therapeutic compositions of the present invention is intended. Additional active pharmaceutical ingredients, such as other drugs, may also be incorporated into the compositions and methods described.
[0699] The terms “about” and “approximately” mean values within a statistically meaningful range. Such a range may be within one order of magnitude of a given value or range, preferably within 50%, more preferably within 20%, more preferably within 10%, and even more preferably within 5%. The permissible variation encompassed by the terms “about” or “approximately” depends on the particular system under test and is readily understandable to those skilled in the art. Furthermore, as used herein, the terms “about” and “approximately” mean that dimensions, sizes, formulations, parameters, shapes, and other quantities and characteristics are not, and do not need to be, exact, and may be approximate and / or greater or less, reflecting tolerances, conversion factors, rounding, measurement errors, and other factors known to those skilled in the art, as necessary. In general, dimensions, sizes, formulations, parameters, shapes, or other quantities or characteristics are “about” or “approximately,” whether so explicitly stated. It should be noted that very different embodiments of size, shape, and dimensions may adopt the configurations described.
[0700] The transitional phrases “contains,” “essentially consists of,” and “consist of,” when used in the original and modified forms in the appended claims, define the claims in terms of whether any additional undescribed claim elements or steps are excluded from the claims. The term “contains” is intended to be inclusive or non-exclusive and does not exclude any additional undescribed elements, methods, steps, or materials. The term “consist of” excludes elements, steps, or materials other than those specified in the claims, and in the latter case, excludes impurities that would ordinarily be associated with the specified materials. The term “essentially consists of” limits the claims to such an extent that it does not substantially affect the specified elements, steps, or materials or the essential and novel features of the claimed invention. All compositions, methods, and kits described herein that embody the present invention may be more specifically defined in alternative embodiments by any of the transitional phrases “contains,” “essentially consists of,” and “consist of.”
[0701] II. TIL Manufacturing Process (Gen3 Process Embodiment, optionally including limited culture medium) In addition to the methods described herein, International Application No. PCT / US2019 / 059718 is incorporated herein by reference in its entirety for all purposes. Not limited to any particular theory, it is believed that the priming of a first proliferation that primes T cell activation, followed by a rapid second proliferation that promotes T cell activation, as described in the methods of the present invention, enables the preparation of proliferated T cells that retain a “younger” phenotype, and therefore the proliferated T cells of the present invention are expected to exhibit greater cytotoxicity against cancer cells than T cells proliferated by other methods. In particular, T cell activation, which is primed by exposure to a first culture supernatant obtained from a first culture of APCs supplemented with an anti-CD3 antibody (e.g., OKT-3), IL-2, and optionally antigen-presenting cells (APCs), or IL-2 and anti-CD3 antibody (e.g., OKT-3), and then boosted by subsequent exposure to a second culture supernatant obtained from a second culture of APCs supplemented with additional anti-CD3 antibody (e.g., OKT-3), IL-2, and APCs, or additional IL-2 and anti-CD3 antibody (e.g., OKT-3), is thought to limit or avoid T cell maturation in culture, as taught by the method of the present invention, resulting in a population of T cells with a less mature phenotype, which are thought to be less depleted by proliferation in culture and exhibit greater cytotoxicity against cancer cells. In some embodiments, the rapid second proliferation step is divided into multiple steps to achieve scaling up the culture by: (a) performing rapid second proliferation by culturing T cells in a small culture in a first container, e.g., a G-REX100MCS container, for about 3-4 days; and then (b) resulting in the transfer of T cells in the small culture to a larger second container, e.g., a G-REX500MCS container, and culturing the T cells from the small culture in the larger culture in the second container for about 4-7 days.In some embodiments, the rapid growth step is divided into multiple steps to achieve scaling out of the culture by: (a) carrying out rapid second growth by culturing the T cells of a first small culture in a first container, e.g., a G-REX100MCS container, for about 3-4 days; and then (b) resulting in the transfer and allocation of the T cells from the first small culture to at least 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 second containers of the same size as the first container, in each second container a portion of the T cells from the first small culture that have been transferred to the second container are cultured in the second small culture for about 4-7 days. In some embodiments, the rapid growth step is divided into multiple steps to achieve scaling out of the culture by: (a) performing a rapid second growth by culturing a small culture of T cells in a first container, e.g., a G-REX100MCS container, for about 3-4 days; and then (b) resulting in the transfer and assignment of the T cell small culture from the first container to at least 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 second containers, e.g., a G-REX500MCS container, which are larger in size than the first container, and in each second container, a portion of the T cells from the small culture transferred to the second container are cultured in the larger culture for about 4-7 days. In some embodiments, the rapid growth step is divided into multiple steps to achieve scaling out of the culture by: (a) performing a rapid second growth by culturing a small culture of T cells in a first container, e.g., a G-REX100MCS container, for 4 days; and then (b) resulting in the transfer and allocation of the T cell culture from the first small culture to two, three, or four second containers larger than the first container, e.g., G-REX500MCS containers, in each of the second containers, a portion of the T cells from the small culture transferred to the second container are cultured in the larger culture for about 5 days.

[0721] In some embodiments, T cells are tumor-infiltrating lymphocytes (TILs).
[0722] In some embodiments, T cells are medullary lymphocytes (MILs).
[0723] In some embodiments, T cells are peripheral blood lymphocytes (PBLs).
[0724] In some embodiments, T cells are obtained from a donor who has cancer.
[0725] In some embodiments, the T cells are TILs obtained from tumors excised from patients with cancer.
[0726] In some embodiments, the T cells are MILs obtained from the bone marrow of patients suffering from hematological malignancies.
[0727] In some embodiments, the T cells are PBLs obtained from peripheral blood mononuclear cells (PBMCs) from a donor. In some embodiments, the donor has cancer. In some embodiments, the cancer is selected from the group consisting of melanoma, ovarian cancer, endometrial cancer, thyroid cancer, colorectal cancer, cervical cancer, non-small cell lung cancer (NSCLC), lung cancer, bladder cancer, breast cancer, cancer derived from human papillomavirus, head and neck cancer (including head and neck squamous cell carcinoma (HNSCC)), glioblastoma (including GBM), gastrointestinal cancer, kidney cancer, and renal cell carcinoma. In some embodiments, the cancer is selected from the group consisting of melanoma, ovarian cancer, cervical cancer, non-small cell lung cancer (NSCLC), lung cancer, bladder cancer, breast cancer, triple-negative breast cancer, cancer derived from human papillomavirus, head and neck cancer (including head and neck squamous cell carcinoma (HNSCC)), glioblastoma (including GBM), gastrointestinal cancer, kidney cancer, and renal cell carcinoma. In some embodiments, the donor has a tumor. In some embodiments, the tumor is a humoral tumor. In some embodiments, the tumor is a solid tumor. In some embodiments, the donor has a hematological malignancy.
[0728] In certain embodiments of this disclosure, immunoeffector cells, such as T cells, may be obtained from blood units collected from a subject using any number of techniques known to those skilled in the art, such as Ficoll isolation. In one preferred embodiment, cells derived from the circulating blood of an individual are obtained by apheresis. The apheresis product typically contains lymphocytes, monocytes, granulocytes, B cells, other nucleated leukocytes, erythrocytes, and platelets, including T cells. In one embodiment, the cells collected by apheresis may be washed to remove the plasma fraction, and optionally, the cells may be placed in a buffer or medium suitable for subsequent processing steps. In one embodiment, the cells are washed with phosphate-buffered saline (PBS). In alternative embodiments, the washing solution may be calcium-deficient, magnesium-deficient, or lack many but not all divalent cations. In one embodiment, T cells are isolated from peripheral blood lymphocytes by lysing erythrocytes and depleting monocytes, for example, by centrifugation with a Percoll gradient or countercurrent centrifugation.
[0729] In some embodiments, the T cells are PBLs isolated from whole blood or lymphocyte-enriched apheresis products from a donor. In some embodiments, the donor has cancer. In some embodiments, the cancer is selected from the group consisting of melanoma, ovarian cancer, endometrial cancer, thyroid cancer, colorectal cancer, cervical cancer, non-small cell lung cancer (NSCLC), lung cancer, bladder cancer, breast cancer, cancer derived from human papillomavirus, head and neck cancer (including head and neck squamous cell carcinoma (HNSCC)), glioblastoma (including GBM), gastrointestinal cancer, kidney cancer, and renal cell carcinoma.

In some embodiments, the donor has a tumor. In some embodiments, the tumor is a humoral tumor. In some embodiments, the tumor is a solid tumor. In some embodiments, the donor has a hematological malignancy. In some embodiments, in the case of a T cell phenotype, PBLs are isolated from whole blood or lymphocyte-enriched apheresis products by using a positive or negative selection method, i.e., using a marker, e.g., CD3+CD45+, or by removing non-T cell phenotype cells to leave the PBLs. In other embodiments, PBLs are isolated by gradient centrifugation. Once PBLs are isolated from the donor tissue, a first proliferation priming of PBLs is performed according to the first proliferation priming step of any of the methods described herein, in a first proliferation priming culture containing a suitable number of isolated PBLs (in some embodiments, approximately 1 × 10⁶). 7 It can be started by sowing seeds (PBL).

[0731] As discussed and outlined herein, TILs are taken from patient samples and manipulated to increase their number before implantation in the patient using a TIL proliferation process described herein and referred to as Gen3. In some embodiments, TILs are manipulated as described below as optional. In some embodiments, TILs may be cryopreserved before or after proliferation. Once thawed, they may also be restimulated to increase their metabolism before injection into the patient.

The following and the order of steps in Figure 1 (e.g., Figure 1B and / or Figure 1C and / or Figure 1E and / or Figure 1F and / or Figure 1G) are illustrative, and any combination or order of steps, as well as additional steps, repetition of steps, and / or omission of steps, are contemplated in the manner disclosed herein and herein.
[0734] A. Step A: Obtain a tumor sample from the patient. Generally, TILs are initially obtained from patient tumor samples ("primary TILs") or from circulating lymphocytes such as peripheral blood lymphocytes containing TIL-like features, and are subsequently grown into larger populations for further manipulation as described herein, optionally cryopreserved, and optionally evaluated for phenotypic and metabolic parameters as indicators of the health status of the TILs.
[0735] Patient tumor samples can be obtained through methods well known in the art, generally surgical excision, needle biopsy, or other means for obtaining a sample containing a mixture of tumor and TIL cells. Generally, tumor samples may originate from any solid tumor, including primary tumors, invasive tumors, or metastatic tumors. Tumor samples may also be humoral tumors, such as tumors obtained from hematological malignancies. Solid tumors may be any cancer type, including but not limited to breast, pancreatic, prostate, colorectal, lung, brain, kidney, stomach, and skin (including but not limited to squamous cell carcinoma, basal cell carcinoma, and melanoma). In some embodiments, cancers are selected from cervical cancer, head and neck cancer (including head and neck squamous cell carcinoma (HNSCC)), glioblastoma (GBM), gastrointestinal cancer, ovarian cancer, sarcoma, pancreatic cancer, bladder cancer, breast cancer, triple-negative breast cancer, and non-small cell lung cancer. Useful TILs are obtained from malignant melanoma tumors, as they have been reported to have particularly high levels of TILs in some embodiments.
[0736] Once obtained, tumor samples are generally cut into 1-8 mm strips using a sharp tool. 3 It is fragmented into small pieces, about 2-3 mm in size. 3 This is particularly useful. TILs are cultured from these fragments using enzymatic tumor digests. Such tumor digests can be produced by incubation in an enzymatic medium (e.g., Roswell Park Memorial Institute (RPMI) 1640 buffer, 2 mM glutamate, 10 mcg / mL gentamicin, 30 units / mL DNase, and 1.0 mg / mL collagenase), followed by mechanical dissociation (e.g., using a tissue dissociation instrument). Tumor digests can be produced by placing the tumor in an enzymatic medium, mechanically dissociating the tumor for approximately 1 minute, then incubating in 5% CO2 at 37°C for 30 minutes, followed by repeating the cycle of mechanical dissociation and incubation under the aforementioned conditions until only small tissue fragments remain. At the end of this process, if the cell suspension contains a large number of erythrocytes or dead cells, these cells can be removed by performing density gradient separation using FICOLL branched hydrophilic polysaccharides. Other methods known in the art, such as the method described in U.S. Patent Application Publication No. 2012 / 0244133 A1, can be used, and their disclosures are incorporated herein by reference. Any of the aforementioned methods can be used in any of the embodiments described herein for methods of growing TILs or treating cancer.

Generally, with bronchoscopy, the patient is anesthetized, and a small instrument is inserted through the nose or mouth, down the throat, and into the bronchial passages, where the small instrument is used to remove tissue. In some embodiments, if the tumor or growth cannot be reached by bronchoscopy, transthoracotomy can be used. Generally, with transthoracotomy, the patient is also anesthetized, and a needle is inserted directly through the skin to the suspected site to remove a small tissue sample. In some embodiments, transthoracotomy may require interventional radiology (e.g., the use of X-rays or CT scans to guide the needle). In some embodiments, the small biopsy is obtained by needle biopsy. In some embodiments, the small biopsy is obtained with endoscopic ultrasound (e.g., an endoscope with a light is inserted through the mouth into the esophagus). In some embodiments, the small biopsy is obtained surgically.
[0769] In some embodiments, the biopsy is a head and neck biopsy. In some embodiments, the biopsy is an incisional biopsy. In some embodiments, the biopsy is an incisional biopsy in which a small piece of tissue is removed from the area that appears abnormal.

[0770] In some embodiments, the small biopsy is a cervical biopsy. In some embodiments, the small biopsy is obtained by colposcopy. Generally, colposcopy involves using an illuminated proliferative instrument attached to a magnifying binocular (colposcope) to biopsy a small portion of the surface of the cervix. In some embodiments, the small biopsy is a cone biopsy. In some embodiments, the small biopsy is a cone biopsy, and outpatient surgery may be required to remove a larger tissue fragment from the cervix. In some embodiments, in addition to helping confirm the diagnosis, a cone biopsy may serve as an initial treatment.
[0771] The term “solid tumor” refers to an abnormal mass of tissue that does not typically contain cysts or fluid areas. Solid tumors can be benign or malignant. The term “solid tumor carcinoma” refers to a malignant, neoplastic, or cancerous solid tumor. Solid tumor carcinomas include, but are not limited to, sarcomas, carcinomas, and lymphomas, such as lung, triple-negative breast cancer, prostate, colon, rectum, and bladder cancers. In some embodiments, cancers are selected from cervical cancer, head and neck cancer, glioblastoma, ovarian cancer, sarcoma, pancreatic cancer, bladder cancer, breast cancer, triple-negative breast cancer, and non-small cell lung cancer.

The concentration of the lyophilized stock enzyme may be 175 DMC / mL. In some embodiments, after reconstitution, the neutral protease stock may have concentrations of approximately 100 DMC / mL to approximately 400 DMC / mL, for example, approximately 100 DMC / mL to approximately 400 DMC / mL, approximately 100 DMC / mL to approximately 350 DMC / mL, approximately 100 DMC / mL to approximately 300 DMC / mL, approximately 150 DMC / mL to approximately 400 DMC / mL, approximately 100 DMC / mL, approximately 110 DMC / mL The range is approximately 120 DMC / ml, 130 DMC / ml, 140 DMC / ml, 150 DMC / ml, 160 DMC / ml, 170 DMC / ml, 175 DMC / ml, 180 DMC / ml, 190 DMC / ml, 200 DMC / ml, 250 DMC / ml, 300 DMC / ml, 350 DMC / ml, or 400 DMC / ml.
[0784] In some embodiments, DNaseI is reconstituted in 1 ml of sterile HBSS or other buffer. The concentration of the lyophilized stock enzyme was 4 KU / vial.

[0787] In some embodiments, the enzyme mixture contains approximately 10.2 µl of neutral protease (0.36 DMCU / ml), 21.3 µl of collagenase (1.2 PZ / ml), and 250 µl of DNAseI (200 U / ml) in approximately 4.7 ml of sterile HBSS.
[0788] 2. Pleural effusion TIL In some embodiments, the sample is a pleural fluid sample. In some embodiments, the source of TILs for growth by the process described herein is a pleural fluid sample. In some embodiments, the sample is a pleural fluid-derived sample. In some embodiments, the source of TILs for growth by the process described herein is a pleural fluid-derived sample. See, for example, the method described in U.S. Patent No. US2014 / 0295426, which is incorporated herein by reference in its entirety for all purposes.
[0789] In some embodiments, any pleural fluid or pleural effusion containing suspected and / or TILs may be used. Such samples may originate from primary or metastatic lung cancer such as NSCLC or SCLC. In some embodiments, the sample may be secondary metastatic cancer cells originating from another organ, e.g., the breast, ovary, colon, or prostate. In some embodiments, the sample for use in the growth method described herein is pleural exudate. In some embodiments, the sample for use in the growth method described herein is pleural effusion. Other biological samples may include other serous fluids containing TILs, e.g., ascites fluid from the abdomen or pancreatic cystic fluid. Ascites fluid and pleural fluid contain very similar chemical systems, and both the abdomen and lung, like malignant tumors, have mesothelial glands and fluid forms in the pleural and abdominal cavities, and in some embodiments, such fluids contain TILs. In some embodiments in which this disclosure exemplified pleural fluid, ascites fluid or other cystic fluid containing TILs may be used and carried out in the same manner having similar results.
[0790] In some embodiments, the pleural fluid is in its untreated form, as taken directly from the patient. In some embodiments, the untreated pleural fluid is placed in a standard blood collection tube, such as an EDTA or heparin tube, before the contact step. In some embodiments, the untreated pleural fluid is placed in a standard CellSave® tube (Veridex) before the contact step. In some embodiments, the sample is placed in a CellSave tube immediately after collection from the patient to avoid a reduction in the number of viable TILs. The number of viable TILs decreases significantly within 24 hours, even at 4°C, if left in untreated pleural fluid. In some embodiments, the sample is placed in a suitable collection tube within 1 hour, 5 hours, 10 hours, 15 hours, or up to 24 hours after excision from the patient. In some embodiments, the sample is placed in a suitable collection tube within 1 hour, 5 hours, 10 hours, 15 hours, or up to 24 hours after excision from the patient, at 4°C.
[0791] In some embodiments, a pleural fluid sample from a selected subject may be diluted. In one embodiment, the dilution is 1:10 pleural fluid to diluent. In another embodiment, the dilution is 1:9 pleural fluid to diluent. In another embodiment, the dilution is 1:8 pleural fluid to diluent. In another embodiment, the dilution is 1:5 pleural fluid to diluent. In another embodiment, the dilution is 1:2 pleural fluid to diluent. In another embodiment, the dilution is 1:1 pleural fluid to diluent. In some embodiments, the diluent includes saline, phosphate-buffered saline, other buffers, or physiologically acceptable diluents. In some embodiments, the sample is placed in a CellSave tube immediately after collection and dilution from the patient to avoid a decrease in viable TILs. This decrease can occur to a considerable extent within 24-48 hours, even at 4°C, if left in untreated pleural fluid. In some embodiments, the pleural fluid sample is collected from the patient and diluted, then placed in a suitable collection tube within 1 hour, 5 hours, 10 hours, 15 hours, 24 hours, 36 hours, and up to 48 hours. In some embodiments, the pleural fluid sample is collected from the patient and diluted, then placed in a suitable collection tube at 4°C within 1 hour, 5 hours, 10 hours, 15 hours, 24 hours, 36 hours, and up to 48 hours.
[0792] In some embodiments, the pleural fluid sample is concentrated by conventional means before further processing steps. In some embodiments, this pretreatment of the pleural fluid is preferred in situations where the pleural fluid must be cryopreserved for transport to the laboratory where the method is performed or for subsequent analysis (e.g., 24-48 hours after collection). In some embodiments, the pleural fluid sample is prepared by centrifugation after the pleural fluid sample is collected from the subject and the centrifugated product or pellet is resuspended in a buffer. In some embodiments, the pleural fluid sample is subjected to multiple centrifugations and resuspensions before transport or cryopreservation for subsequent analysis and / or processing.
[0793] In some embodiments, the pleural fluid sample is concentrated before further processing steps by using a filtration method. In some embodiments, the pleural fluid sample to be used in the contact step is prepared by filtering the fluid through a filter having a known and essentially uniform pore size that allows the pleural fluid to pass through a membrane but retains tumor cells. In some embodiments, the pore diameter of the membrane may be at least 4 μM. In other embodiments, the pore diameter may be 5 μM or greater, and in other embodiments, it may be 6, 7, 8, 9, or 10 μM. After filtration, the cells containing the TILs retained by the membrane can be washed from the membrane and placed in a suitable physiologically acceptable buffer. The cells containing the TILs thus concentrated can then be used in the contact step of the method.
[0794] In some embodiments, a pleural fluid sample (e.g., including untreated pleural fluid), diluted pleural fluid, or resuspended cell pellet is brought into contact with a lysis reagent that selectively lyses anucleated red blood cells present in the sample. In some embodiments, this step is performed before further processing steps, in situations where the pleural fluid contains a significant number of RBCs. Suitable lysis reagents include single lysis reagents or lysis reagents and quench reagents, or lysis reagents, quench reagents, and fixation reagents. Suitable lysis systems are commercially available and include the BD Pharm Lyse® system (Becton Dickenson). Other lysis systems include the Versalyse® system, FACSlyse® system (Becton Dickenson), Immunoprep® system or Erythrolyse II system (Beckman Coulter, Inc.), or ammonium chloride systems. In some embodiments, the lysis reagent may differ depending on the primary requirements, which are efficient lysis of red blood cells and preservation of the phenotypic properties of TILs in the pleural fluid. In addition to using a single reagent for dissolution, a dissolution system useful for the method described herein may include a second reagent, for example, one that quenches or delays the effect of the dissolving reagent during the remaining steps of the method, such as Stabilyse® reagent (Beckman Coulter). Depending on the choice of dissolving reagent or the preferred method, conventional fixation reagents may also be used.
[0795] In some embodiments, untreated, diluted, or multi-centrifugation or treated pleural fluid samples are frozen and stored at a temperature of about -140°C before further processing and / or development as provided herein.
