[001] This international PCT application claims priority to U.S. Provisional Application No. 62 / 733,937, filed on September 20, 2018, and U.S. Provisional Application No. 62 / 879,881, filed on July 29, 2019. FIELD OF THE INVENTION

[002] The invention described herein relates generally to the expansion of lymphocytes and more particularly, but not exclusively, to expansion of lymphocytes from cryopreserved tumor tissue. BACKGROUND OF THE INVENTION

[003] Treatment of refractory cancers using adoptive transfer of tumor infiltrating lymphocytes (TILs) represents a potentially powerful approach to treat patients with poor prognoses. Gattinoni, et al., Nat. Rev. Immunol. 2006, 6, 383-393. Successful immunotherapy requires a large number of TILs; therefore, a robust and reliable process is needed for manufacturing and commercialization. This scaling for commercialization has been a profound challenge because of the legion technical, logistical, and regulatory issues with cell expansion. IL-2-based TIL expansion followed by a "rapid expansion process" (REP) has become a preferred method for TIL expansion because of its 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. A REP can result in a 1,000-fold expansion of TILs over a 14-day period, although it requires a large excess (e.g., 200-fold) of irradiated allogeneic peripheral blood mononuclear cells (PBMCs, also known as mononuclear cells (MNCs)), often from multiple donors, as feeder cells, as well as anti-CD3 antibody (OKT3) and high doses of IL-2. Dudley, et al., J. Immunother. 2003, 26, 332-42. TILs that have undergone a REP procedure have produced successful adoptive cell therapy following host immunosuppression in some melanoma patients.

[004] Current TIL manufacturing processes are limited by duration, cost, sterility concerns, and other factors described herein such that the potential to commercialize such processes is severely limited. Among the many limitations of the current processes is the dependence on fresh tumor tissue to initiate manufacturing, which often necessitates expensive and costly local manufacturing facilities because of the difficulty in shipping fresh tumor longer distances. There is an urgent need to provide TIL manufacturing processes and therapies that are not dependent on fresh tumor tissue and that are appropriate for commercial scale manufacturing and regulatory approval for use in geographically widely dispersed human patients.

[0060] Figure 12: Depicts the major steps of the 1 / 100th scale TIL production process.

[0061] Figure 13: Figures 13A-13E depict total viable cells (TVC) for tumor samples processed from 5 different patients and collected during pre-REP. TVC was measured using fresh (Gen2 control) and frozen tumor samples. TVC was recorded on day 11 for fresh tumor samples or day 7 for frozen tumor samples. Figure 13A (patient M1125) shows the only patient whose tumor samples were subjected to different freezing methods: flash freezing in the vapor phase of liquid nitrogen, and incubation at 2-8° Celsius for either 30 or 60 minutes prior to flash freezing in the vapor phase of liquid nitrogen. For the remaining patients S13018, OV8022, T6042, and O8026 (FIGS. 13B-13E, respectively), the tumor samples were incubated at 2-8° for 60 minutes prior to flash freezing. For each patient, tumor samples were sectioned in 3mm diameter fragments and 4-6 fragments were used for culture. Each bar on the graph represents TVC extrapolated to full scale (multiplied by 10). In FIG 13A, frozen, early pre-REP culture yielded about 1% TVC as compared to fresh, FIG. 13B, about 25% TVC as compared to fresh, FIG. 13C, about 200% as compared to fresh, FIG 13D, about 96% as compared to fresh, and FIG. 13E, about 3% as compared with fresh. The data indicate that TVC from frozen tumor samples on Day 7 is comparable to TVC from fresh tumor samples on Day 11.

[0062] Figure 14: Figures 14A-14E depict TVC for tumor samples from the same 5 patients as Figure 13, collected during early REP. Cells were harvested on Day 11 (fresh) and Day 7 (frozen) as described in Figure 13. In FIG 14A, frozen, early REP culture yielded about 86% TVC as compared to fresh, FIG. 14B, about 98% TVC as compared to fresh, FIG. 14C, about 124% as compared to fresh, FIG 14D, about 286% as compared to fresh, and FIG. 14E, about 167% as compared with fresh. The data indicate that overall yield (measured as TVC) from frozen tumor samples on Day 7 is comparable to TVC from fresh tumor samples on Day 11 during early REP.

[0063] Figure 15: Figure 15 depicts the CD8 / CD4 ratio in fresh and frozen tumor samples from 4 patients. Fresh or frozen REP TIL samples were stained with flow cytometry antibodies (CD3-BUV395, CD62LBV421, CD57-PB, CD11c-BV711, CD28-BB515, CD19-BUV563, CCR7-PE, CD123-BV605, CD27PE-CF594, CD14-BV-650, TCRg / d-APC, CD45-PerCP-Cy5.5, CD45RA-A700, CD56-BUV737, CD8-BV786, CD4-PE-Cy7AND CD16-APC-Vio770). The identity of TIL were determined based on TCR a / b+ or g / d+, monocytes (CD14+), NK (CD56+, CD16+, CD56+ / CD16+ and B cells (CD19+) and purity was determined based on CD3+CD45+ cells. Patients M1125 and T6042 demonstrated high CD8 expression, but overall the CD8 / CD4 ratio is comparable between fresh and frozen tumor samples.

[0064] Figure 16: Figures 16A-16H depict CD3+CD45+ expression and other marker expression in the same 4 patients as Figure 15. Figures 16A and 16B depict data for patient M1125; Figures 16C and 16D for patient S13018; Figures 16E and 16F for patient OV8022; and Figures 16G and 16H for patient T6042.

Activation and exhaustion of REP TIL was determined by multicolor flow cytometry. Tumor tissue was stained with antibodies (CD3- BUV395, PD-1-BV421, 2B4 / CD244-PB, CD8-BB515, CD25-BUV563, BTLA-PE, KLRG1-PE- Dazzle 594, TIM-3-BV650, CD194 / CCR4-APC, CD4-VioGreen, TIGIT-PerCP-eFluor 710, CD183-BV711, CD69-APC-R700, CD95-BUV737, CD127-PE-Cy7, CD103-BV786, LAG-3- APC-eFluor 780) and expression was measured using flow cytometry. Overall, TIL activation / exhaustion status is comparable between fresh and frozen tumor samples.

[0068] Figure 20: Figures 20A-20C illustrate IFNy function in fresh and frozen tumor samples for 3 patients: M1125 (FIG 20A); S13018 (FIG. 20B); and T6042 (FIG. 20C). 1x105 REP TIL were plated in anti-CD3 plates for 24 hours. Culture supernatants were collected and measured for IFNy cytokine using an IFNy Qantikine ELISA kit. Bar graph represent here are Mean + SD of triplicate measurement. Student 't' test was used to calculate statistical significance. * P < 0.05, ** P < 0.01, *** P < 0.001. Overall, the data demonstrate that IFNy function is higher in frozen tumor samples.

[0069] Figure 21: Figures 21A-21C illustrate Granzyme B (GzmB) function in fresh and frozen tumor samples for 3 patients: M1125 (FIG 21A); S13018 (FIG. 21B); and T6042 (FIG. 21C). 1x105 REP TIL were plated in anti-CD3 plates for 24 hours. Culture supernatants were collected and measured for Granzyme B using a Duo set ELISA kit. Bar graph represent here are Mean + SD of triplicate measurement. Student 't' test was used to calculate statistical significance. * P <semantics><0.05<annotation encoding="application / x-tex">< 0.05< / annotation>< / semantics>, ** P <semantics><0.01<annotation encoding="application / x-tex">< 0.01< / annotation>< / semantics>, *** P <semantics><0.001<annotation encoding="application / x-tex">< 0.001< / annotation>< / semantics>. Overall, the data demonstrate that Granzyme B (GzmB) function is comparable / higher in frozen tumor samples.

[0070] Figure 22: Figures 22A-22C illustrate CD107A expression in fresh and frozen tumor samples for 3 patients: M1125 (FIG 22A); S13018 (FIG. 22B); and T6042 (FIG. 22C). 2x105 REP TIL were stimulated with or without stimulation of PMA / IO for 2 hours, then stained for CD107A-APC700 and analyzed by flow cytometry. Bar graph represents CD107A positive cells gated on CD8 or CD4. Overall, the data demonstrate that CD107A expression is comparable between fresh and frozen tumor samples.

[0071] Figure 23: Figures 23A-23C illustrate telomere length relative to 1301 cells in fresh and frozen tumor samples for 3 patients: M1125 (FIG 23A); S13018 (FIG. 23B); and T6042 (FIG. 23C). Flow-FISH was performed using Dako / Agilent Pathology Solutions (Telomere PNA) Kit / FITC for Flow Cytometry) kit and the manufacturer's instructions were followed to measure the average length of the Telomere repeat. 1301 T-cell leukemia cell line (SigmaAldrich, St. Louis, MO)) was used as an internal reference standard in each assay. Individual TIL were counted and mixed with 1301 cells at a 1:1 cell ratio. <semantics>2×106<annotation encoding="application / x-tex">2 \times 10^6< / annotation>< / semantics> TIL were mixed with <semantics>2×106<annotation encoding="application / x-tex">2 \times 10^6< / annotation>< / semantics> 1301 cells, in situ hybridization was performed using FITC-conjugated Telomere PNA probe (FITC- 00-CCCTAA-CCC-TAA) and analyzed using Flow cytometry (BD canto II). Telomere fluorescence of the test sample was expressed as a percentage of the geometric mean fluorescence (fl) of the 1301 cells per the following formula: Relative telomere length = [(mean FITC fl test cells w / probe-mean FITC fl test cells w / o probe) × DNA index of 1301 cells × 100] / [(mean FITC fl 1301 cells w / probe – mean FITC fl 1301 cells w / o probe) × DNA index of test cells. The data indicate that telomere length is comparable or better in frozen tumor samples than fresh tumor samples.

[00261] The term "rapid expansion" means an increase in the number of antigen-specific TILs of at least about 3-fold (or 4-, 5-, 6-, 7-, 8-, or 9-fold) over a period of a week, more preferably at least about 10-fold (or 20-, 30-, 40-, 50-, 60-, 70-, 80-, or 90-fold) over a period of a week, or most preferably at least about 100-fold over a period of a week. A number of rapid expansion protocols are outlined below.

[00262] By "tumor infiltrating lymphocytes" or "TILs" herein is meant a population of cells originally obtained as white blood cells that have left the bloodstream of a subject and migrated into a tumor. TILs include, but are not limited to, CD8+ cytotoxic T cells (lymphocytes), Th1 and Th17 CD4+ T cells, natural killer cells, dendritic cells and M1 macrophages. TILs include both primary and secondary TILs. "Primary TILs" are those that are obtained from patient tissue samples as outlined herein (sometimes referred to as "freshly harvested"), and "secondary TILs" are any TIL cell populations that have been expanded or proliferated as discussed herein, including, but not limited to bulk TILs and expanded TILs ("REP TILs" or "post-REP TILs"). TIL cell populations can include genetically modified TILs.

[00263] By "population of cells" (including TILs) herein is meant a number of cells that share common traits. In general, populations generally range from <semantics>1×106<annotation encoding="application / x-tex">1 \times 10^6< / annotation>< / semantics> to <semantics>1×1010<annotation encoding="application / x-tex">1 \times 10^{10}< / annotation>< / semantics> in number, with different TIL populations comprising different numbers. For example, initial growth of primary TILs in the presence of IL-2 results in a population of bulk TILs of roughly <semantics>1×108<annotation encoding="application / x-tex">1 \times 10^8< / annotation>< / semantics> cells. REP expansion is generally done to provide populations of <semantics>1.5×109<annotation encoding="application / x-tex">1.5 \times 10^9< / annotation>< / semantics> to <semantics>1.5×1010<annotation encoding="application / x-tex">1.5 \times 10^{10}< / annotation>< / semantics> cells for infusion.

[00264] By "cryopreserved TILs" herein is meant that TILs, either primary, bulk, or expanded (REP TILs), are treated and stored at a temperature in the range of about -150°C to -60°C. General methods for cryopreservation are also described elsewhere herein, including in the Examples. For clarity and the avoidance of doubt, "cryopreserved TILs" are distinguishable from frozen tissue samples which may be used as a source of primary TILs.

[00265] By "thawed cryopreserved TILs" herein is meant a population of TILs that was previously cryopreserved and then treated to return to room temperature or higher, including but not limited to cell culture temperatures or temperatures wherein TILs may be administered to a patient.

[00266] TILs can generally be defined either biochemically, using cell surface markers, or functionally, by their ability to infiltrate tumors and effect treatment. TILs can be generally categorized by expressing one or more of the following biomarkers: CD4, CD8, TCR αβ, CD27, CD28, CD56, CCR7, CD45Ra, CD95, PD-1, and CD25. Additionally, and alternatively, TILs can be functionally defined by their ability to infiltrate solid tumors upon reintroduction into a patient.

[00267] The term "cryopreservation media" or "cryopreservation medium" refers to any medium that can be used for cryopreservation of cells. Such media can include media comprising 5% v / v DMSO to 10% v / v DMSO; such media can also include media comprising 7% v / v DMSO to 10% v / v DMSO. Exemplary media include CryoStor CS10, Hyperthermasol, as well as combinations thereof. The term "CS10" refers to a cryopreservation medium which is obtained from Stemcell Technologies or from Biolife Solutions. The CS10 medium may be referred to by the trade name "CryoStor® CS10". The CS10 medium is a serum-free, animal component-free medium which comprises DMSO.

[00268] The term "central memory T cell" refers to a subset of T cells that in the human are CD45R0+ and constitutively express CCR7 (CCR7hi) and CD62L (CD62hi). The surface phenotype of central memory T cells also includes TCR, CD3, CD127 (IL-7R), and IL-15R. Transcription factors for central memory T cells include BCL-6, BCL-6B, MBD2, and BMI1. Central memory T cells primarily secrete IL-2 and CD40L as effector molecules after TCR triggering. Central memory T cells are predominant in the CD4 compartment in blood, and in the human are proportionally enriched in lymph nodes and tonsils.

[00269] The term "effector memory T cell" refers to a subset of human or mammalian T cells that, like central memory T cells, are CD45R0+, but have lost the constitutive expression of CCR7 (CCR7lo) and are heterogeneous or low for CD62L expression (CD62Llo). The surface phenotype of central memory T cells also includes TCR, CD3, CD127 (IL-7R), and IL-15R. Transcription factors for central memory T cells include BLIMP1. Effector memory T cells rapidly secret high levels of inflammatory cytokines following antigenic stimulation, including interferon-γ, IL-4, and IL-5. Effector memory T cells are predominant in the CD8 compartment in blood, and in the human are proportionally enriched in the lung, liver, and gut. CD8+ effector memory T cells carry large amounts of perforin.

[00270] The term "closed system" refers to a system that is closed to the outside environment. Any closed system appropriate for cell culture methods can be employed with the methods of the present invention. Closed systems include, for example, but are not limited to closed G- containers.

Except insofar as any conventional pharmaceutically acceptable carrier or pharmaceutically acceptable excipient is incompatible with the active pharmaceutical ingredient, its use in the therapeutic compositions of the invention is contemplated. Additional active pharmaceutical ingredients, such as other drugs, can also be incorporated into the described compositions and methods.

[00283] When ranges are used herein to describe, for example, physical or chemical properties such as molecular weight or chemical formulae, all combinations and subcombinations of ranges and specific embodiments therein are intended to be included. Use of the term "about" when referring to a number or a numerical range means that the number or numerical range referred to is an approximation within experimental variability (or within statistical experimental error), and thus the number or numerical range may vary. The variation is typically from 0% to 15%, preferably from 0% to 10%, more preferably from 0% to 5% of the stated number or numerical range. The term "comprising" (and related terms such as "comprise" or "comprises" or "having" or "including") includes those embodiments such as, for example, an embodiment of any composition of matter, method or process that "consist of" or "consist essentially of" the described features.

[00284] Compounds of the invention also include antibodies. The terms "antibody" and its plural form "antibodies" refer to whole immunoglobulins and any antigen-binding fragment ("antigen-binding portion") or single chains thereof. An "antibody" further refers to a glycoprotein comprising at least two heavy (H) chains and two light (L) chains inter-connected by disulfide bonds, or an antigen-binding portion thereof. Each heavy chain is comprised of a heavy chain variable region (abbreviated herein as VH) and a heavy chain constant region. The heavy chain constant region is comprised of three domains, CH1, CH2 and CH3. Each light chain is comprised of a light chain variable region (abbreviated herein as VL) and a light chain constant region. The light chain constant region is comprised of one domain, CL. The VH and VL regions of an antibody may be further subdivided into regions of hypervariability, which are referred to as complementarity determining regions (CDR) or hypervariable regions (HVR), and which can be interspersed with regions that are more conserved, termed framework regions (FR). Each VH and VL is composed of three CDRs and four FRs, arranged from amino-terminus to carboxy-terminus in the following order: FR1, CDR1, FR2, CDR2, FR3, CDR3, FR4. The variable regions of the heavy and light chains contain a binding domain that interacts with an antigen epitope or epitopes. The constant regions of the antibodies may mediate the binding of the immunoglobulin to host tissues or factors, including various cells of the immune system (e.g., effector cells) and the first component (Clq) of the classical complement system.

[00285] The terms "antigen-binding portion" or "antigen-binding fragment" of an antibody (or simply "antibody portion"), as used herein, refers to one or more fragments of an antibody that retain the ability to specifically bind to an antigen (e.g., IL-33, ST2, CD20, PD-1, PD-L1, or PD- L2). It has been shown that the antigen-binding function of an antibody can be performed by fragments of a full-length antibody. Examples of binding fragments encompassed within the term "antigen-binding portion" of an antibody include (i) a Fab fragment, a monovalent fragment consisting of the VL, VH, CL and CH1 domains; (ii) a F(ab')2 fragment, a bivalent fragment comprising two Fab fragments linked by a disulfide bridge at the hinge region; (iii) a Fd fragment consisting of the VH and CH1 domains; (iv) a Fv fragment consisting of the VL and VH domains of a single arm of an antibody, (v) a domain antibody (dAb) fragment (Ward et al., Nature, 1989, 341, 544-546), which may consist of a VH or a VL domain; and (vi) an isolated complementarity determining region (CDR). Furthermore, although the two domains of the Fv fragment, VL and VH, are coded for by separate genes, they can be joined, using recombinant methods, by a synthetic linker that enables them to be made as a single protein chain in which the VL and VH regions pair to form monovalent molecules known as single chain Fv (scFv); see, e.g., Bird et al., Science 1988, 242, 423-426; and Huston et al., Proc. Natl. Acad. Sci. USA 1988, 85, 5879-5883). Such scFv antibodies are also intended to be encompassed within the terms "antigen-binding portion" or "antigen-binding fragment" of an antibody. These antibody fragments are obtained using conventional techniques known to those with skill in the art, and the fragments are screened for utility in the same manner as are intact antibodies.

[00286] The term "human antibody," as used herein, is intended to include antibodies having variable regions in which both the framework and CDR regions are derived from human germline immunoglobulin sequences. Furthermore, if the antibody contains a constant region, the constant region also is derived from human germline immunoglobulin sequences. The human antibodies of the invention may include amino acid residues not encoded by human germline immunoglobulin sequences (e.g., mutations introduced by random or site-specific mutagenesis in vitro or by somatic mutation in vivo). The term "human antibody", as used herein, is not intended to include antibodies in which CDR sequences derived from the germline of another mammalian species, such as a mouse, have been grafted onto human framework sequences.

[00287] The term "human monoclonal antibody" refers to antibodies displaying a single binding specificity which have variable regions in which both the framework and CDR regions are derived from human germline immunoglobulin sequences. In one embodiment, the human monoclonal antibodies are produced by a hybridoma which includes a B cell obtained from a transgenic nonhuman animal, e.g., a transgenic mouse, having a genome comprising a human heavy chain transgene and a light chain transgene fused to an immortalized cell.

[00288] The term "recombinant human antibody", as used herein, includes all human antibodies that are prepared, expressed, created or isolated by recombinant means, such as (a) antibodies isolated from an animal (e.g., a mouse) that is transgenic or transchromosomal for human immunoglobulin genes or a hybridoma prepared therefrom (described further below), (b) antibodies isolated from a host cell transformed to express the human antibody, e.g., from a transfectoma, (c) antibodies isolated from a recombinant, combinatorial human antibody library, and (d) antibodies prepared, expressed, created or isolated by any other means that involve splicing of human immunoglobulin gene sequences to other DNA sequences. Such recombinant human antibodies have variable regions in which the framework and CDR regions are derived from human germline immunoglobulin sequences. In certain embodiments, however, such recombinant human antibodies can be subjected to in vitro mutagenesis (or, when an animal transgenic for human Ig sequences is used, in vivo somatic mutagenesis) and thus the amino acid sequences of the VH and VL regions of the recombinant antibodies are sequences that, while derived from and related to human germline VH and VL sequences, may not naturally exist within the human antibody germline repertoire in vivo.

[00289] As used herein, "isotype" refers to the antibody class (e.g., IgM or IgG1) that is encoded by the heavy chain constant region genes. In mammals, there are five antibody isotypes: IgA, IgD, IgG, IgM and IgE. In humans, there are four subclasses of the IgG isotype: IgG1, IgG2, IgG3 and IgG4, and two subclasses of the IgA isotype: IgA1 and IgA2.

[00290] The phrases "an antibody recognizing an antigen" and "an antibody specific for an antigen" are used interchangeably herein with the term "an antibody which binds specifically to an antigen."

[00291] The term "human antibody derivatives" refers to any modified form of the human antibody, e.g., a conjugate of the antibody and another active pharmaceutical ingredient or antibody. The terms "conjugate," "antibody-drug conjugate", "ADC," or "immunoconjugate" refers to an antibody, or a fragment thereof, conjugated to a therapeutic moiety, such as a bacterial toxin, a cytotoxic drug or a radionuclide-containing toxin. Toxic moieties can be conjugated to antibodies of the invention using methods available in the art.

[00292] The terms "humanized antibody," "humanized antibodies," and "humanized" are intended to refer to antibodies in which CDR sequences derived from the germline of another mammalian species, such as a mouse, have been grafted onto human framework sequences. Additional framework region modifications may be made within the human framework sequences. Humanized forms of non-human (for example, murine) antibodies are chimeric antibodies that contain minimal sequence derived from non-human immunoglobulin. For the most part, humanized antibodies are human immunoglobulins (recipient antibody) in which residues from a hypervariable region of the recipient are replaced by residues from a 15 hypervariable region of a non-human species (donor antibody) such as mouse, rat, rabbit or nonhuman primate having the desired specificity, affinity, and capacity. In some instances, Fv framework region (FR) residues of the human immunoglobulin are replaced by corresponding non-human residues. Furthermore, humanized antibodies may comprise residues that are not found in the recipient antibody or in the donor antibody. These modifications are made to further refine antibody performance. In general, the humanized antibody will comprise substantially all of at least one, and typically two, variable domains, in which all or substantially all of the hypervariable loops correspond to those of a non-human immunoglobulin and all or substantially all of the FR regions are those of a human immunoglobulin sequence. The humanized antibody optionally also will comprise at least a portion of an immunoglobulin constant region (Fc), typically that of a human immunoglobulin. For further details, see Jones et al., Nature 1986, 321, 522-525; Riechmann et al., Nature 1988, 332, 323-329; and Presta, Curr. Op. Struct. Biol. 1992, 2, 593-596.

[00293] The term "chimeric antibody" is intended to refer to antibodies in which the variable region sequences are derived from one species and the constant region sequences are derived from another species, such as an antibody in which the variable region sequences are derived from a mouse antibody and the constant region sequences are derived from a human antibody.

[00294] A "diabody" is a small antibody fragment with two antigen-binding sites. The fragments comprises a heavy chain variable domain (VH) connected to a light chain variable domain (VL) in the same polypeptide chain (VH-VL or VL-VH). By using a linker that is too short to allow pairing between the two domains on the same chain, the domains are forced to pair with the complementary domains of another chain and create two antigen-binding sites. Diabodies are described more fully in, e.g., European Patent No. EP 404,097, International Patent Publication No. WO 93 / 11161; and Bolliger et al., Proc. Natl. Acad. Sci. USA 1993, 90, 6444-6448.

[00295] The term "glycosylation" refers to a modified derivative of an antibody. An aglycoslated antibody lacks glycosylation. Glycosylation can be altered to, for example, increase the affinity of the antibody for antigen. Such carbohydrate modifications can be accomplished by, for example, altering one or more sites of glycosylation within the antibody sequence. For example, one or more amino acid substitutions can be made that result in elimination of one or more variable region framework glycosylation sites to thereby eliminate glycosylation at that site. Aglycosylation may increase the affinity of the antibody for antigen, as described in U.S. Patent Nos. 5,714,350 and 6,350,861. Additionally, or alternatively, an antibody can be made that has an altered type of glycosylation, such as a hypofucosylated antibody having reduced amounts of fucosyl residues or an antibody having increased bisecting GlcNac structures. Such altered glycosylation patterns have been demonstrated to increase the ability of antibodies. Such carbohydrate modifications can be accomplished by, for example, expressing the antibody in a host cell with altered glycosylation machinery. Cells with altered glycosylation machinery have been described in the art and can be used as host cells in which to express recombinant antibodies of the invention to thereby produce an antibody with altered glycosylation. For example, the cell lines Ms704, Ms705, and Ms709 lack the fucosyltransferase gene, FUT8 (alpha (1,6) fucosyltransferase), such that antibodies expressed in the Ms704, Ms705, and Ms709 cell lines lack fucose on their carbohydrates. The Ms704, Ms705, and Ms709 FUT8- / - cell lines were created by the targeted disruption of the FUT8 gene in CHO / DG44 cells using two replacement vectors (see e.g. U.S. Patent Publication No. 2004 / 0110704 or Yamane-Ohnuki, et al. Biotechnol. Bioeng., 2004, 87, 614-622). As another example, European Patent No. EP 1,176,195 describes a cell line with a functionally disrupted FUT8 gene, which encodes a fucosyl transferase, such that antibodies expressed in such a cell line exhibit hypofucosylation by reducing or eliminating the alpha 1,6 bond-related enzyme, and also describes cell lines which have a low enzyme activity for adding fucose to the N-acetylglucosamine that binds to the Fc region of the antibody or does not have the enzyme activity, for example the rat myeloma cell line YB2 / 0 (ATCC CRL 1662). International Patent Publication WO 03 / 035835 describes a variant CHO cell line, Lec 13 cells, with reduced ability to attach fucose to Asn(297)-linked carbohydrates, also resulting in hypofucosylation of antibodies expressed in that host cell (see also Shields, et al., J. Biol. Chem. 2002, 277, 26733-26740. International Patent Publication WO 99 / 54342 describes cell lines engineered to express glycoprotein-modifying glycosyl transferases (e.g., beta(1,4)-N-acetylglucosaminyltransferase III (GnTIII)) such that antibodies expressed in the engineered cell lines exhibit increased bisecting GlcNac structures which results in increased ADCC activity of the antibodies (see also Umana, et al., Nat. Biotech. 1999, 17, 176-180). Alternatively, the fucose residues of the antibody may be cleaved off using a fucosidase enzyme. For example, the fucosidase alpha-L-fucosidase removes fucosyl residues from antibodies as described in Tarentino, et al., Biochem. 1975, 14, 5516-5523.

[00296] "Pegylation" refers to a modified antibody, or a fragment thereof, that typically is reacted with polyethylene glycol (PEG), such as a reactive ester or aldehyde derivative of PEG, under conditions in which one or more PEG groups become attached to the antibody or antibody fragment. Pegylation may, for example, increase the biological (e.g., serum) half life of the antibody. Preferably, the pegylation is carried out via an acylation reaction or an alkylation reaction with a reactive PEG molecule (or an analogous reactive water-soluble polymer). As used herein, the term "polyethylene glycol" is intended to encompass any of the forms of PEG that have been used to derivatize other proteins, such as mono (C1-C10) alkoxy- or aryloxy- polyethylene glycol or polyethylene glycol-maleimide. The antibody to be pegylated may be an aglycosylated antibody. Methods for pegylation are known in the art and can be applied to the antibodies of the invention, as described for example in European Patent Nos. EP 0154316 and EP 0401384.

[00297] The term "biosimilar" means a biological product that is highly similar to a U.S. licensed reference biological product notwithstanding minor differences in clinically inactive components, and for which there are no clinically meaningful differences between the biological product and the reference product in terms of the safety, purity, and potency of the product. Furthermore, a similar biological or "biosimilar" medicine is a biological medicine that is similar to another biological medicine that has already been authorized for use by the European Medicines Agency. The term "biosimilar" is also used synonymously by other national and regional regulatory agencies. Biological products or biological medicines are medicines that are made by or derived from a biological source, such as a bacterium or yeast. They can consist of relatively small molecules such as human insulin or erythropoietin, or complex molecules such as monoclonal antibodies. For example, if the reference anti-CD20 monoclonal antibody is rituximab, an anti-CD20 biosimilar monoclonal antibody approved by drug regulatory authorities with reference to rituximab is a "biosimilar to" rituximab or is a "biosimilar thereof" of rituximab. In Europe, a similar biological or "biosimilar" medicine is a biological medicine that is similar to another biological medicine that has already been authorized for use by the European Medicines Agency (EMA). The relevant legal basis for similar biological applications in Europe is Article 6 of Regulation (EC) No 726 / 2004 and Article 10(4) of Directive 2001 / 83 / EC, as amended and therefore in Europe, the biosimilar may be authorised, approved for authorisation or subject of an application for authorisation under Article 6 of Regulation (EC) No 726 / 2004 and Article 10(4) of Directive 2001 / 83 / EC. The already authorized original biological medicinal product may be referred to as a "reference medicinal product" in Europe. Some of the requirements for a product to be considered a biosimilar are outlined in the CHMP Guideline on Similar Biological Medicinal Products. In addition, product specific guidelines, including guidelines relating to monoclonal antibody biosimilars, are provided on a product-by-product basis by the EMA and published on its website. A biosimilar as described herein may be similar to the reference medicinal product by way of quality characteristics, biological activity, mechanism of action, safety profiles and / or efficacy. In addition, the biosimilar may be used or be intended for use to treat the same conditions as the reference medicinal product. Thus, a biosimilar as described herein may be deemed to have similar or highly similar quality characteristics to a reference medicinal product. Alternatively, or in addition, a biosimilar as described herein may be deemed to have similar or highly similar biological activity to a reference medicinal product. Alternatively, or in addition, a biosimilar as described herein may be deemed to have a similar or highly similar safety profile to a reference medicinal product. Alternatively, or in addition, a biosimilar as described herein may be deemed to have similar or highly similar efficacy to a reference medicinal product. As described herein, a biosimilar in Europe is compared to a reference medicinal product which has been authorised by the EMA. However, in some instances, the biosimilar may be compared to a biological medicinal product which has been authorised outside the European Economic Area (a non-EEA authorised "comparator") in certain studies. Such studies include for example certain clinical and in vivo non-clinical studies. As used herein, the term "biosimilar" also relates to a biological medicinal product which has been or may be compared to a non-EEA authorised comparator. Certain biosimilars are proteins such as antibodies, antibody fragments (for example, antigen binding portions) and fusion proteins. A protein biosimilar may have an amino acid sequence that has minor modifications in the amino acid structure (including for example deletions, additions, and / or substitutions of amino acids) which do not significantly affect the function of the polypeptide. The biosimilar may comprise an amino acid sequence having a sequence identity of 97% or greater to the amino acid sequence of its reference medicinal product, <semantics>e.g.<annotation encoding="application / x-tex">e.g.< / annotation>< / semantics>, 97%, 98%, 99% or 100%. The biosimilar may comprise one or more post-translational modifications, for example, although not limited to, glycosylation, oxidation, deamidation, and / or truncation which is / are different to the post-translational modifications of the reference medicinal product, provided that the differences do not result in a change in safety and / or efficacy of the medicinal product. The biosimilar may have an identical or different glycosylation pattern to the reference medicinal product. Particularly, although not exclusively, the biosimilar may have a different glycosylation pattern if the differences address or are intended to address safety concerns associated with the reference medicinal product. Additionally, the biosimilar may deviate from the reference medicinal product in for example its strength, pharmaceutical form, formulation, excipients and / or presentation, providing safety and efficacy of the medicinal product is not compromised. The biosimilar may comprise differences in for example pharmacokinetic (PK) and / or pharmacodynamic (PD) profiles as compared to the reference medicinal product but is still deemed sufficiently similar to the reference medicinal product as to be authorised or considered suitable for authorisation. In certain circumstances, the biosimilar exhibits different binding characteristics as compared to the reference medicinal product, wherein the different binding characteristics are considered by a Regulatory Authority such as the EMA not to be a barrier for authorisation as a similar biological product. The term "biosimilar" is also used synonymously by other national and regional regulatory agencies.

[00298] The term "hematological malignancy" refers to mammalian cancers and tumors of the hematopoietic and lymphoid tissues, including but not limited to tissues of the blood, bone marrow, lymph nodes, and lymphatic system. Hematological malignancies are also referred to as "liquid tumors." Hematological malignancies include, but are not limited to, ALL, CLL, SLL, acute myelogenous leukemia (AML), chronic myelogenous leukemia (CML), acute monocytic leukemia (AMoL), Hodgkin's lymphoma, and non-Hodgkin's lymphomas. The term "B cell hematological malignancy" refers to hematological malignancies that affect B cells.

[00299] The term "solid tumor" refers to an abnormal mass of tissue that usually does not contain cysts or liquid areas. Solid tumors may be benign or malignant. The term "solid tumor cancer" refers to malignant, neoplastic, or cancerous solid tumors. Solid tumor cancers include, but are not limited to, sarcomas, carcinomas, and lymphomas, such as cancers of the lung, breast, prostate, colon, rectum, and bladder. The tissue structure of solid tumors includes interdependent tissue compartments including the parenchyma (cancer cells) and the supporting stromal cells in which the cancer cells are dispersed and which may provide a supporting microenvironment.

[00300] The term "liquid tumor" refers to an abnormal mass of cells that is fluid in nature. Liquid tumor cancers include, but are not limited to, leukemias, myelomas, and lymphomas, as well as other hematological malignancies. TILs obtained from liquid tumors may also be referred to herein as marrow infiltrating lymphocytes (MILs).

[00301] The term "microenvironment," as used herein, may refer to the solid or hematological tumor microenvironment as a whole or to an individual subset of cells within the microenvironment. The tumor microenvironment, as used herein, refers to a complex mixture of "cells, soluble factors, signaling molecules, extracellular matrices, and mechanical cues that promote neoplastic transformation, support tumor growth and invasion, protect the tumor from host immunity, foster therapeutic resistance, and provide niches for dominant metastases to thrive," as described in Swartz, et al., Cancer Res., 2012, 72, 2473. Although tumors express antigens that should be recognized by T cells, tumor clearance by the immune system is rare because of immune suppression by the microenvironment.

[00302] In an embodiment, the invention includes a method of treating a cancer with a population of TILs, wherein a patient is pre-treated with non-myeloablative chemotherapy prior to an infusion of TILs according to the invention. In some embodiments, the population of TILs may be provided wherein a patient is pre-treated with nonmyeloablative chemotherapy prior to an infusion of TILs according to the present invention. In an embodiment, the non-myeloablative chemotherapy is cyclophosphamide 60 mg / kg / d for 2 days (days 27 and 26 prior to TIL infusion) and fludarabine 25 mg / m2 / d for 5 days (days 27 to 23 prior to TIL infusion). In an embodiment, after non-myeloablative chemotherapy and TIL infusion (at day 0) according to the invention, the patient receives an intravenous infusion of IL-2 intravenously at 720,000 IU / kg every 8 hours to physiologic tolerance.

[00303] Experimental findings indicate that lymphodepletion prior to adoptive transfer of tumor-specific T lymphocytes plays a key role in enhancing treatment efficacy by eliminating regulatory T cells and competing elements of the immune system ("cytokine sinks"). Accordingly, some embodiments of the invention utilize a lymphodepletion step (sometimes also referred to as "immunosuppressive conditioning") on the patient prior to the introduction of the rTILs of the invention

[00304] The terms "sequence identity," "percent identity," and "sequence percent identity" in the context of two or more nucleic acids or polypeptides, refer to two or more sequences or subsequences that are the same or have a specified percentage of nucleotides or amino acid residues that are the same, when compared and aligned (introducing gaps, if necessary) for maximum correspondence, not considering any conservative amino acid substitutions as part of the sequence identity. The percent identity can be measured using sequence comparison software or algorithms or by visual inspection. Various algorithms and software are known in the art that can be used to obtain alignments of amino acid or nucleotide sequences. Suitable programs to determine percent sequence identity include for example the BLAST suite of programs available from the U.S. Government's National Center for Biotechnology Information BLAST web site. Comparisons between two sequences can be carried using either the BLASTN or BLASTP algorithm. BLASTN is used to compare nucleic acid sequences, while BLASTP is used to compare 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. One skilled in the art can determine appropriate parameters for maximal alignment by particular alignment software. In certain embodiments, the default parameters of the alignment software are used.

[00305] Certain embodiments of the present invention comprise a variant of an antibody, e.g., an anti-IL-33 or anti-ST2 antibody and / or an anti-CD20 antibody and / or an anti-PD-1 antibody, anti-PD-L1 and / or an anti-PD-L2 antibody. As used herein, the term "variant" encompasses but is not limited to antibodies which comprise an amino acid sequence which differs from the amino acid sequence of a reference antibody by way of one or more substitutions, deletions and / or additions at certain positions within or adjacent to the amino acid sequence of the reference antibody. The variant may comprise one or more conservative substitutions in its amino acid sequence as compared to the amino acid sequence of a reference antibody. Conservative substitutions may involve, e.g., the substitution of similarly charged or uncharged amino acids. The variant retains the ability to specifically bind to the antigen of the reference antibody.

[00319] In some embodiments, the tumor tissue is washed in a physiologically buffered isotonic saline solution. In some embodiments, the washing comprises three serial washes of at least three minutes each, with the physiologically buffered isotonic saline solution replaced after each serial wash. In some embodiments, the physiologically buffered isotonic saline solution comprises Hank's Balance Salt Solution (HBSS).

[00320] In an embodiment, the freezing takes place at a temperature in the range from about - 125°C to about -196°C. In an embodiment, the freezing takes place at a temperature in the range of about -140°C to about -185°C. In an embodiment, the freezing takes place at a temperature in the range of about -140°C to about -175°C. In an embodiment, the freezing takes place at a temperature of about -145°C. In some embodiments, the freezing takes place in the vapor phase of liquid nitrogen.

[00321] A problem well-known in the art is to cryopreserve cells or tissues without damaging them during the freezing process. Without being bound by theory, one source of damage during freezing is intracellular ice nucleation resulting in cellular rupture. Muldrew and McGann outline a quantitative theory for this well known and widely recognized difficulty with cellular and, in particular, whole tissue cryopreservation in "The osmotic rupture hypothesis of intracellular freezing injury", Biophysical Journal, 66:532-41 (1994). Acker and McGann further develop the fundamental mechanisms of intracellular ice formation and cellular damage in a later article, "Membrane damage occurs during the formation of intracellular ice," Cryo Letter, 22:241-54 (2001).

[00322] Damage during freezing is detected wherein upon thawing, the tissues have substantially lost their physiological structures or the cells comprising the tissue have substantially lost their viability. Viability may be determined by the fraction of cells introduced into a culture medium compared to the number of such cells that grow or show markers of normal cellular function. Numerous methods are known in the art to identify the fraction of viable cells, for example, and without limitation, dye exclusion tests, such as trypan blue exclusion. See, for example, Strober, Curr. Protoc. Immunol., 2001, Appendix 3B, available at https: / / dx.doi.org / 10.1002 / 0471142735.ima03bs21. Without limitation, viability may also be determined by metabolic activity assays, such as the MTT assay, wherein MTT, 3-(4,5- dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, is metabolized by cellular enzymes into formazan. This enzymatic reaction converts the yellow MTT into purple formazan. See, for example, Berridge et al., Tetrazolium dyes as tools in cell biology: new insights into their cellular reduction. Biotechnology Annual Review, 11: 127-152 (2005); Mosmann, "Rapid colorimetric assay for cellular growth and survival: application to proliferation and cytotoxicity assays," J. Immunol. Methods 65 (1-2): 55-63 (1983).

[00323] Without being bound by theory, slow cooling is hypothesized to produce innocuous intracellular ice, see Acker and McGann, "Protective effect of intracellular ice during freezing?" Cryobiology, 46(2): 197-202 (2003). A conventional approach to achieve freezing without excessive cellular damage or to achieve freezing without significantly reducing cellular viability has been to employ slow freezing rates. Watson et al., U.S. Patent 5,891,617, emphasize this approach, for example claim one, step (c), teaches a very slow rate of cooling: "about -0.3° C. per minute or less." Similarly, Comhaire et al., U.S. Patent 9,938,495, teach "high cell viability after thawing were obtained by slow freezing using a DMSO-free cryopreservation medium" for stem cells.

[00324] Based on these exemplary teachings, the methods and products of the present disclosure are surprising and unexpected.

[00438] There are various methods to expand TILs known to one skilled in the art. For example, Jin et al., J. Immunother. 35(3): 283-292 (2012), "Simplified Method of the Growth of Human Tumor Infiltrating Lymphocytes in Gas-permeable Flasks to Numbers Needed for Patient Treatment," teaches simplified methods of producing TILs for clinical use. Jin et al. teaches a first TIL culture followed by a rapid expansion (REP) protocol, which combined, enables one skilled in the art to produce clinically useful quantities of TILs. In some embodiments, the invention provides a method of manufacturing TILs comprising the step of cryopreserving a tumor, thawing a tumor, and performing the process described in Jin et al. Briefly, this process involves the following process. TILs may initially be cultured from enzymatic tumor digests and tumor fragments (about 1 to 8 mm3) produced by sharp dissection. Tumor digests are produced by incubation in enzyme media (RPMI 1640, 2 mM GlutaMAX, 10 mg / mL gentamicin, 30U / mL DNase, and 1.0 mg / mL collagenase) followed by mechanical dissociation (GentleMACS, Miltenyi Biotec, Auburn, CA). Immediately after placing the tumor in enzyme media, it is mechanically dissociated for approximately 1 minute. The material was then incubated for 30 minutes at 37°C in 5% CO2 and is then mechanically disrupted again for approximately 1 minute and incubated again for 30 minutes at 37°C in 5% CO2. The tumor is then mechanically disrupted a third time for approximately 1 minute. If after the third mechanical disruption, large pieces of tissue were present, 1 or 2 additional mechanical dissociations may be applied to the sample, with or without 30 additional minutes of incubation at 37°C in 5% CO2. At the end of the final incubation, if the cell suspension contained a large number of red blood cells or dead cells, a density gradient separation using Ficoll may be performed to remove these cells. When TIL cultures are initiated in 24-well plates (Costar 24-well cell culture cluster, flat bottom; Corning Incorporated, Corning, NY), each well is seeded with <semantics>1×106<annotation encoding="application / x-tex">1 \times 10^6< / annotation>< / semantics> tumor digest cells or one tumor fragment approximately about 1 to 8 mm3 in size in 2 mL of complete medium (CM) with IL-2 (6000 IU / mL; Chiron Corp., Emeryville, CA). CM comprised RPMI 1640 with GlutaMAX, supplemented with 10% human AB serum, 25mM Hepes, and about 10 μg / mL gentamicin. When cultures were initiated in gas-permeable flasks with a 40 mL capacity and a 10 cm2 gas-permeable silicon bottom (G- Rex10; Wilson Wolf Manufacturing, New Brighton, MN), each flask is loaded with 10 to <semantics>40×106<annotation encoding="application / x-tex">40 \times 10^6< / annotation>< / semantics> viable tumor digest cells or 5 to 30 tumor fragments in 10 to 40 mL of CM with IL-2. Both the G-Rex10 and 24-well plates are incubated in a humidified incubator at 37°C in 5%CO2 and 5 days after culture initiation, half the media is removed and replaced with fresh CM and IL-2 and after day 5, half the media is changed every 2-3 days. REP of TIL is performed using T-175 flasks and gas-permeable bags or gas-permeable G-Rex flasks. For TIL REP in T-175 flasks, 1×106 TILs suspended in 150 mL of media was added to each T-175 flask. The TIL were cultured with irradiated (50 Gy) allogeneic PBMC as "feeder" cells at a ratio of 1 to 100 and the cells are cultured in a 1 to 1 mixture of CM and AIM-V medium (50 / 50 medium), supplemented with 3000 IU / mL of IL-2 and 30 ng / mL of anti-CD3. The T-175 flasks are incubated at 37°C in 5% CO2. Half the media is changed on day 5 using 50 / 50 medium with 3000 IU / mL of IL-2. On day 7, cells from 2 T-175 flasks are combined in a 3L bag and 300 mL of AIM-V with 5% human AB serum and 3000 IU / mL of IL-2 is added to the 300 mL of TIL suspension. The number of cells in each bag was counted every day or 2 and fresh media was added to keep the cell count between 0.5 and 2.0×106 cells / mL. For TIL REP in 500mL capacity flasks with 100 cm2 gas-permeable silicon bottoms (G-Rex100, Wilson Wolf), 5×106 to 10×106 TIL are cultured with irradiated allogeneic PBMC at a ratio of 1 to 100 in 400 mL of 50 / 50 medium, supplemented with 3000 IU / mL of IL-2 and 30 ng / mL of anti-CD3. G-Rex100 flasks are incubated at 37°C in 5% CO2. On day 5, 250 mL of supernatant is removed and placed into centrifuge bottles and centrifuged at 1500 rpm (491 g) for 10 minutes. TIL pellets are resuspended with 150 mL of fresh 50 / 50 medium with 3000 IU / mL of IL-2 and added back to the original G-Rex100 flasks. When TIL are expanded serially in G-Rex100 flasks, on day 7 the TIL in each G-Rex100 were suspended in the 300 mL of media present in each flask and the cell suspension was divided into three 100 mL aliquots that were used to seed 3 G-Rex100 flasks. 150 mL of AIM-V with 5% human AB serum and 3000 IU / mL of IL-2 is added to each flask. The G-Rex100 flasks are incubated at 37°C in 5% CO2 and after 4 days 150 mL of AIM-V with 3000 IU / mL of IL-2 was added to each G-Rex100 flask. The cells are harvested on day 14 of culture.

[00439] In some embodiments, the expansion methods according to the present invention comprises preparing expansion of cells from frozen tumor. Tumor samples are collected from patients and cryopreserved according to methods disclosed herein. When ready to expand the cells, for a process performed at the 1 / 100th scale, about six 2-3 mm diameter frozen tumor fragments are thawed using a <semantics>37∘<annotation encoding="application / x-tex">37^{\circ}< / annotation>< / semantics>C water bath for <semantics>5+1<annotation encoding="application / x-tex">5 + 1< / annotation>< / semantics> minutes and washed in sterile Hanks Balanced Salt Solution (HBSS) supplemented with gentamicin. The fragments are then placed into a G-Rex 10M flask (Wilson Wolf Mfg., New Brighton, MN) or other gas permeable container with CM1 media or a serum-free or defined media containing about 6,000 IU / mL of rhIL-2. These pre-REP (or first expansion) cultures are incubated for 5 days in a 37°C incubator. On day 5, the pre-REP cells are harvested, and the REP (or second expansion) is initiated by co-culturing 10% of the pre-REP TILs with either 25x106 or 50x106 PBMC feeder cells in CM2 media or a serum-free or defined media containing 3,000 IU / mL rhIL-2 and 30 ng / mL of OKT-3 in a G-Rex 5M flask (Wilson Wolf Mfg., New Brighton, MN) or other gas permeable container. On day 10, the culture is split into G-Rex 5M flasks or other gas permeable container containing no more than <semantics>10x106<annotation encoding="application / x-tex">10x10^6< / annotation>< / semantics> cells. The split cultures are incubated for 6 additional days in CM4 media or other serum-free or defined media containing 3,000 IU / mL rhIL-2. On day 16, the cells are harvested and frozen using CryoStor10 (Biolife, USA). This process is referred to herein as the "Early REP Method 1" process or "ER-1."

On day 3, the pre-REP cells are harvested, and the REP (or second expansion) is initiated by co- culturing 10% of the pre-REP TILs with either 25x106 or 50x106 PBMC feeder cells in CM2 media or a serum-free or defined media containing 3,000 IU / mL rhIL-2 and 30 ng / mL of OKT-3 in a G-Rex 5M flask (Wilson Wolf Mfg., New Brighton, MN) or other gas permeable container.

On day 16, the cells are harvested and frozen using CryoStor10 (Biolife, USA). This process is referred to herein as the "Early REP Method 2" process or "ER-2."

[00441] In some embodiments, the invention provides a method of manufacturing TILs comprising the step of cryopreserving a tumor, thawing a tumor, and performing the following process. TILs can be produced by rapid expansion using stimulation of peripheral blood mononuclear cells (PBMC) in vitro with an antigen (one or more, including antigenic portions thereof, such as epitope(s), or a cell) of the cancer, which can be optionally expressed from a vector, such as an HLA-A2 binding peptide, e.g., 0.3 μM MART-1:26-35 (27L) or gp100:209- 217 (210M), in the presence of a T-cell growth factor, such as 300 IU / mL IL-2 or IL-15, with IL- 2 being preferred. The in vitro-induced TILs are rapidly expanded by re-stimulation with the same antigen(s) of the cancer pulsed onto HLA-A2-expressing antigen-presenting cells. Alternatively, the TILs can be re-stimulated with irradiated, autologous lymphocytes or with irradiated HLA-A2+ allogeneic lymphocytes and IL-2, for example. TILs can be selected for highly avid recognition of any of the unique antigens produced as a result of the estimated 10,000 genetic mutations encoded by each tumor cell genome. The antigen, however, need not be unique. T-cells can be selected for highly avid recognition of one or more antigens of a cancer, including an antigenic portion of one or more antigens, such as an epitope, or a cell of the cancer. An "antigen of a cancer" and an "antigen of the cancer" are intended to encompass all of the aforementioned antigens. If the cancer is melanoma, such as metastatic melanoma, preferably the TILs are selected for highly avid recognition of MART-1 (such as MART-1:26- 35 (27L)), gp100 (such as gp100:209-217 (210M)), or a "unique" or patient-specific antigen derived from a tumor encoded mutation. Other suitable melanoma antigens for which highly avid recognition by TILs can be selected include, but are not limited to, tyrosinase, tyrosinase related protein (TRP)1, TRP2, and MAGE. Antigens, such as NY-ESO-1, telomerase, p53, HER2 / neu, carcinoembryonic antigen, or prostate-specific antigen, can be used to select for highly avid recognition by TILs for treatment of lung carcinoma, breast cancer, colon cancer, prostate cancer, and the like TILs can be selected include, but are not limited to, tyrosinase, tyrosinase related protein.

[00442] IL-2-based TIL expansion followed by a "rapid expansion process" (REP) has become a preferred method for TIL expansion because of its 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 result in a 1,000-fold expansion of TILs over a 14-day period, although it requires a large excess (e.g., 200-fold) of irradiated allogeneic peripheral blood mononuclear cells (PBMCs), often from multiple donors, as feeder cells, as well as anti- CD3 antibody (OKT3) and high doses of IL-2. Dudley, et al., J. Immunother. 2003, 26, 332-42. The cryopreserved tumor fragments are suitable starting points for initial or first cultures to manufacture TILs for therapeutic or other purposes.

[00443] An exemplary TIL process known as process 2A containing some of these features is depicted in Figure 1. Another exemplary TIL process, known as process 1C, is described and compared to process 2A in Figures 5 and 6. An embodiment of process 2A is shown Figure 1.

[00444] As discussed herein, the present invention can include a step relating to the restimulation of cryopreserved TILs to increase their metabolic activity and thus relative health prior to transplant into a patient, and methods of testing said metabolic health. As generally outlined herein, TILs are generally taken from a patient sample and manipulated to expand their number prior to transplant into a patient. In some embodiments, the TILs may be optionally genetically manipulated as discussed below.

[00445] In some embodiments, the TILs may be cryopreserved and thawed for administration to a patient. Once thawed, they may also be restimulated to increase their metabolism prior to infusion into a patient.

[00446] In some embodiments, the first expansion (including processes referred to as the preREP as well as processes shown in Figure 1 as Step A) is shortened to 3 to 14 days and the second expansion (including processes referred to as the REP as well as processes shown in Figure 1 as Step B) is shorted to 7 to 14 days, as discussed in detail below as well as in the examples and figures. In some embodiments, the first expansion (for example, an expansion described as Step B in Figure 1) is shortened to 11 days and the second expansion (for example, an expansion as described in Step D in Figure 1) is shortened to 11 days. In some embodiments, the combination of the first expansion and second expansion (for example, expansions described as Step B and Step D in Figure 1) is shortened to 22 days, as discussed in detail below and in the examples and figures.

[00447] The "Step" Designations A, B, C, etc., below are in reference to Figure 1 and in reference to certain embodiments described herein. The ordering of the Steps below and in Figure 1 is exemplary and any combination or order of steps, as well as additional steps, repetition of steps, and / or omission of steps is contemplated by the present application and the methods disclosed herein. Step A. Obtain Patient Tumor Sample

[00448] In general, TILs are initially obtained from a patient tumor sample ("primary TILs") and then expanded into a larger population for further manipulation as described herein, optionally cryopreserved, restimulated as outlined herein and optionally evaluated for phenotype and metabolic parameters as an indication of TIL health.

[00449] A patient tumor sample may be obtained using methods known in the art, generally via surgical resection, needle biopsy or other means for obtaining a sample that contains a mixture of tumor and TIL cells. In general, the tumor sample may be from any solid tumor, including primary tumors, invasive tumors or metastatic tumors. The tumor sample may also be a liquid tumor, such as a tumor obtained from a hematological malignancy. The solid tumor may be of any cancer type, including, but not limited to, breast, pancreatic, prostate, colorectal, lung, brain, renal, stomach, and skin (including but not limited to squamous cell carcinoma, basal cell carcinoma, and melanoma). In some embodiments, useful TILs are obtained from malignant melanoma tumors, as these have been reported to have particularly high levels of TILs.

[00450] The term "solid tumor" refers to an abnormal mass of tissue that usually does not contain cysts or liquid areas. Solid tumors may be benign or malignant. The term "solid tumor cancer" refers to malignant, neoplastic, or cancerous solid tumors. Solid tumor cancers include, but are not limited to, sarcomas, carcinomas, and lymphomas, such as cancers of the lung, breast, triple negative breast cancer, prostate, colon, rectum, and bladder. In some embodiments, the cancer is selected from cervical cancer, head and neck cancer (including, for example, head and neck squamous cell carcinoma (HNSCC) glioblastoma, ovarian cancer, sarcoma, pancreatic cancer, bladder cancer, breast cancer, triple negative breast cancer, and non-small cell lung carcinoma. The tissue structure of solid tumors includes interdependent tissue compartments including the parenchyma (cancer cells) and the supporting stromal cells in which the cancer cells are dispersed and which may provide a supporting microenvironment.

[00451] The term "hematological malignancy" refers to mammalian cancers and tumors of the hematopoietic and lymphoid tissues, including but not limited to tissues of the blood, bone marrow, lymph nodes, and lymphatic system. Hematological malignancies are also referred to as "liquid tumors." Hematological malignancies include, but are not limited to, acute lymphoblastic leukemia (ALL), chronic lymphocytic lymphoma (CLL), small lymphocytic lymphoma (SLL), acute myelogenous leukemia (AML), chronic myelogenous leukemia (CML), acute monocytic leukemia (AMoL), Hodgkin's lymphoma, and non-Hodgkin's lymphomas. The term "B cell hematological malignancy" refers to hematological malignancies that affect B cells.

[00452] Once obtained, the tumor sample is generally fragmented using sharp dissection into small pieces of between 1 to about 8 mm3, with from about 2-3 mm3 being particularly useful. The TILs are cultured from these fragments using enzymatic tumor digests. Such tumor digests may be produced by incubation in enzymatic media (e.g., Roswell Park Memorial Institute (RPMI) 1640 buffer, 2 mM glutamate, 10 mcg / mL gentamicin, 30 units / mL of DNase and 1.0 mg / mL of collagenase) followed by mechanical dissociation (e.g., using a tissue dissociator). Tumor digests may be produced by placing the tumor in enzymatic media and mechanically dissociating the tumor for approximately 1 minute, followed by incubation for 30 minutes at 37 °C in 5% CO2, followed by repeated cycles of mechanical dissociation and incubation under the foregoing conditions until only small tissue pieces are present. At the end of this process, if the cell suspension contains a large number of red blood cells or dead cells, a density gradient separation using FICOLL branched hydrophilic polysaccharide may be performed to remove these cells. Alternative methods known in the art may be used, such as those described in U.S. Patent Application Publication No. 2012 / 0244133 A1. Any of the foregoing methods may be used in any of the embodiments described herein for methods of expanding TILs or methods treating a cancer.

[00453] In general, the harvested cell suspension is called a "primary cell population" or a "freshly harvested" cell population.

[00454] In some embodiments, fragmentation includes physical fragmentation, including for example, dissection as well as digestion. In some embodiments, the fragmentation is physical fragmentation. In some embodiments, the fragmentation is dissection. In some embodiments, the fragmentation is by digestion. In some embodiments, TILs can be initially cultured from enzymatic tumor digests and tumor fragments obtained from patients. In an embodiment, TILs can be initially cultured from enzymatic tumor digests and tumor fragments obtained from patients.

[00455] In some embodiments, where the tumor is a solid tumor, the tumor undergoes physical fragmentation after the tumor sample is obtained in, for example, Step A (as provided in Figure 1). In some embodiments, the fragmentation occurs before cryopreservation. In some embodiments, the fragmentation occurs after cryopreservation. In some embodiments, the fragmentation occurs after obtaining the tumor and in the absence of any cryopreservation. In some embodiments, the tumor is fragmented and 10, 20, 30, 40 or more fragments or pieces are placed in each container for the first expansion. In some embodiments, the tumor is fragmented and 30 or 40 fragments or pieces are placed in each container for the first expansion. In some embodiments, the tumor is fragmented and 40 fragments or pieces are placed in each container for the first expansion. In some embodiments, the multiple fragments comprise about 4 to about 50 fragments, wherein each fragment has a volume of about 27 mm3. In some embodiments, the multiple fragments comprise about 30 to about 60 fragments with a total volume of about 1300 mm3 to about 1500 mm3. In some embodiments, the multiple fragments comprise about 50 fragments with a total volume of about 1350 mm3. In some embodiments, the multiple fragments comprise about 50 fragments with a total mass of about 1 gram to about 1.5 grams. In some embodiments, the multiple fragments comprise about 4 fragments.

[00456] In some embodiments, the TILs are obtained from tumor fragments. In some embodiments, the tumor fragment is obtained by sharp dissection. In some embodiments, the tumor fragment is between about 1 mm3 and 10 mm3. In some embodiments, the tumor fragment is between about 1 mm3 and 8 mm3. In some embodiments, the tumor fragment is about 1 mm3. In some embodiments, the tumor fragment is about 2 mm3. In some embodiments, the tumor fragment is about 3 mm3. In some embodiments, the tumor fragment is about 4 mm3. In some embodiments, the tumor fragment is about 5 mm3. In some embodiments, the tumor fragment is about 6 mm3. In some embodiments, the tumor fragment is about 7 mm3. In some embodiments, the tumor fragment is about 8 mm3. In some embodiments, the tumor fragment is about 9 mm3. In some embodiments, the tumor fragment is about 10 mm3. In some embodiments, the tumors are 1-4 mm <semantics>×<annotation encoding="application / x-tex">\times< / annotation>< / semantics> 1-4 mm <semantics>×<annotation encoding="application / x-tex">\times< / annotation>< / semantics> 1-4 mm. In some embodiments, the tumors are 1 mm <semantics>×<annotation encoding="application / x-tex">\times< / annotation>< / semantics> 1 mm <semantics>×<annotation encoding="application / x-tex">\times< / annotation>< / semantics> 1 mm. In some embodiments, the tumors are 2 mm <semantics>×<annotation encoding="application / x-tex">\times< / annotation>< / semantics> 2 mm. In some embodiments, the tumors are 3 mm <semantics>×<annotation encoding="application / x-tex">\times< / annotation>< / semantics> 3 mm <semantics>×<annotation encoding="application / x-tex">\times< / annotation>< / semantics> 3 mm. In some embodiments, the tumors are 4 mm <semantics>×<annotation encoding="application / x-tex">\times< / annotation>< / semantics> 4 mm <semantics>×<annotation encoding="application / x-tex">\times< / annotation>< / semantics> 4 mm. In embodiments wherein the tumor tissue is first frozen before initiating a culture, tumors are about <semantics>6 mm×6 mm×6 mm<annotation encoding="application / x-tex">6 \text{ mm} \times 6 \text{ mm} \times 6 \text{ mm}< / annotation>< / semantics>.

[00457] In some embodiments, the tumors are resected in order to minimize the amount of hemorrhagic, necrotic, and / or fatty tissues on each piece. In some embodiments, the tumors are resected in order to minimize the amount of hemorrhagic tissue on each piece. In some embodiments, the tumors are resected in order to minimize the amount of necrotic tissue on each piece. In some embodiments, the tumors are resected in order to minimize the amount of fatty tissue on each piece.

[00458] In some embodiments, the tumor fragmentation is performed in order to maintain the tumor internal structure. In some embodiments, the tumor fragmentation is performed without preforming a sawing motion with a scalpel. In some embodiments, the TILs are obtained from tumor digests. In some embodiments, tumor digests were generated by incubation in enzyme media, for example but not limited to RPMI 1640, 2 mM GlutaMAX, 10 μg / mL gentamicin, 30 U / mL DNase, and 1.0 mg / mL collagenase, followed by mechanical dissociation (GentleMACS, Miltenyi Biotec, Auburn, CA). After placing the tumor in enzyme media, the tumor can be mechanically dissociated for approximately 1 minute. The solution can then be incubated for 30 minutes at 37 °C in 5% CO2 and it then mechanically disrupted again for approximately 1 minute. After being incubated again for 30 minutes at 37 °C in 5% CO2, the tumor can be mechanically disrupted a third time for approximately 1 minute. In some embodiments, after the third mechanical disruption if large pieces of tissue were present, 1 or 2 additional mechanical dissociations were applied to the sample, with or without 30 additional minutes of incubation at 37 °C in 5% CO2. In some embodiments, at the end of the final incubation if the cell suspension contained a large number of red blood cells or dead cells, a density gradient separation using Ficoll can be performed to remove these cells.

[00459] In some embodiments, the harvested cell suspension prior to the first expansion step is called a "primary cell population" or a "freshly harvested" cell population.

[00460] In some embodiments, cells can be optionally frozen after sample harvest and stored frozen prior to entry into the expansion described in Step B, which is described in further detail below, as well as exemplified in Figure 1. Step B: First Expansion

[00461] In some embodiments, the present methods provide for obtaining young TILs, which are capable of increased replication cycles upon administration to a subject / patient and as such may provide additional therapeutic benefits over older TILs (for example "older TILs" have further undergone more rounds of ex vivo replication prior to administration to a subject / patient). Features of young TILs have been described in the literature, for example Donia, et al., Scandinavian Journal of Immunology, 75:157–167 (2012); Dudley et al., Clin Cancer Res, 16:6122-6131 (2010); Huang et al., J Immunother, 28(3):258–267 (2005); Besser et al., Clin Cancer Res, 19(17):OF1-OF9 (2013); Besser et al., J Immunother, 32:415–423 (2009); Robbins, et al., J Immunol, 2004; 173:7125-7130; Shen et al., J Immunother, 30:123-129 (2007); Zhou, et al., J Immunother, 28:53–62 (2005); and Tran, et al., J Immunother, 31:742–751 (2008).

[00462] The diverse antigen receptors of T and B lymphocytes are produced by somatic recombination of a limited, but large number of gene segments. These gene segments: V (variable), D (diversity), J (joining), and C (constant), determine the binding specificity and downstream applications of immunoglobulins and T-cell receptors (TCRs). The present invention provides a method for generating TILs which exhibit and increase the T-cell repertoire diversity. In some embodiments, the TILs obtained by the present method exhibit an increase in the T-cell repertoire diversity. In some embodiments, the TILs obtained by the present method exhibit an increase in the T-cell repertoire diversity as compared to freshly harvested TILs and / or TILs prepared using other methods than those provide herein including for example, methods other than those embodied in Figure 1. In some embodiments, the TILs obtained by the present method exhibit an increase in the T-cell repertoire diversity as compared to freshly harvested TILs and / or TILs prepared using methods referred to as process 1C, as exemplified in Figure 5 and / or Figure 6. In some embodiments, the TILs obtained in the first expansion exhibit an increase in the T-cell repertoire diversity. In some embodiments, the increase in diversity is an increase in the immunoglobulin diversity and / or the T-cell receptor diversity. In some embodiments, the diversity is in the immunoglobulin is in the immunoglobulin heavy chain. In some embodiments, the diversity is in the immunoglobulin is in the immunoglobulin light chain. In some embodiments, the diversity is in the T-cell receptor. In some embodiments, the diversity is in one of the T-cell receptors selected from the group consisting of alpha, beta, gamma, and delta receptors.

[00481] In some embodiments, the TILs obtained from the first expansion (for example, from Step B as indicated in Figure 1) are stored until phenotyped for selection. In some embodiments, the TILs obtained from the first expansion (for example, from Step B as indicated in Figure 1) are not stored and proceed directly to the second expansion. In some embodiments, the TILs obtained from the first expansion are not cryopreserved after the first expansion and prior to the second expansion.

In some embodiments, the transition occurs in closed system, as described herein. In some embodiments, the TILs from the first expansion, the second population of TILs, proceeds directly into the second expansion with no transition period.

[00484] In some embodiments, the transition from the first expansion to the second expansion, for example, Step C according to Figure 1, is performed in a closed system bioreactor. In some embodiments, a closed system is employed for the TIL expansion, as described herein. In some embodiments, a single bioreactor is employed. In some embodiments, the single bioreactor employed is for example a G-REX-10 or a G-REX-100. In some embodiments, the closed system bioreactor is a single bioreactor. Cytokines

[00485] The expansion methods described herein generally use culture media with high doses of a cytokine, in particular IL-2, as is known in the art.

[00486] Alternatively, using combinations of cytokines for the rapid expansion and or second expansion of TILs is additionally possible, with combinations of two or more of IL-2, IL-15 and IL-21 as is generally outlined in International Publication No. WO 2015 / 189356 and W International Publication No. WO 2015 / 189357. Thus, possible combinations include IL-2 and IL-15, IL-2 and IL-21, IL-15 and IL- 21 and IL-2, IL-15 and IL-21, with the latter finding particular use in many embodiments. The use of combinations of cytokines specifically favors the generation of lymphocytes, and in particular T-cells as described therein. Step D: Second Expansion

[00487] In some embodiments, the TIL cell population is expanded in number after harvest and initial bulk processing for example, after Step A and Step B, and the transition referred to as Step C, as indicated in Figure 1). This further expansion is referred to herein as the second expansion, which can include expansion processes generally referred to in the art as a rapid expansion process (REP; as well as processes as indicated in Step D of Figure 1). The second expansion is generally accomplished using a culture media comprising a number of components, including feeder cells, a cytokine source, and an anti-CD3 antibody, in a gas-permeable container.

[00488] In some embodiments, the second expansion or second TIL expansion (which can include expansions sometimes referred to as REP; as well as processes as indicated in Step D of Figure 1) of TIL can be performed using any TIL flasks or containers known by those of skill in the art. In some embodiments, the second TIL expansion can proceed for 7 days, 8 days, 9 days, 10 days, 11 days, 12 days, 13 days, or 14 days. In some embodiments, the second TIL expansion can proceed for about 7 days to about 14 days. In some embodiments, the second TIL expansion can proceed for about 8 days to about 14 days. In some embodiments, the second TIL expansion can proceed for about 9 days to about 14 days. In some embodiments, the second TIL expansion can proceed for about 10 days to about 14 days. In some embodiments, the second TIL expansion can proceed for about 11 days to about 14 days. In some embodiments, the second TIL expansion can proceed for about 12 days to about 14 days. In some embodiments, the second TIL expansion can proceed for about 13 days to about 14 days. In some embodiments, the second TIL expansion can proceed for about 14 days.

[00489] In an embodiment, the second expansion can be performed in a gas permeable container using the methods of the present disclosure (including for example, expansions referred to as REP; as well as processes as indicated in Step D of Figure 1). For example, TILs can be rapidly expanded using non-specific T-cell receptor stimulation in the presence of interleukin-2 (IL-2) or interleukin-15 (IL-15). The non-specific T-cell receptor stimulus can include, for example, an anti-CD3 antibody, such as about 30 ng / ml of OKT3, a mouse monoclonal anti-CD3 antibody (commercially available from Ortho-McNeil, Raritan, NJ or Miltenyi Biotech, Auburn, CA) or UHCT-1 (commercially available from BioLegend, San Diego, CA, USA). TILs can be expanded to induce further stimulation of the TILs in vitro by including one or more antigens during the second expansion, including antigenic portions thereof, such as epitope(s), of the cancer, which can be optionally expressed from a vector, such as a human leukocyte antigen A2 (HLA-A2) binding peptide, e.g., 0.3 µM MART-1:26-35 (27) L) or gpl 00:209-217 (210M), optionally in the presence of a T-cell growth factor, such as 300 IU / mL IL-2 or IL-15. Other suitable antigens may include, e.g., NY-ESO-1, TRP-1, TRP-2, tyrosinase cancer antigen, MAGE-A3, SSX-2, and VEGFR2, or antigenic portions thereof. TIL may also be rapidly expanded by re-stimulation with the same antigen(s) of the cancer pulsed onto HLA-A2-expressing antigen-presenting cells.

Media replacement is done (generally 2 / 3 media replacement via respiration with fresh media) until the cells are transferred to an alternative growth chamber. Alternative growth chambers include G-REX flasks and gas permeable containers as more fully discussed below.

[00500] In some embodiments, the second expansion (which can include processes referred to as the REP process) is shortened to 7-14 days, as discussed in the examples and figures. In some embodiments, the second expansion is shortened to 11 days.

[00501] In an embodiment, REP and / or the second expansion may be performed using T-175 flasks and gas permeable bags as previously described (Tran, et al., J. Immunother, 2008, 31, 742-51; Dudley, et al., J. Immunother, 2003, 26, 332-42) or gas permeable cultureware (G-Rex flasks). In some embodiments, the second expansion (including expansions referred to as rapid expansions) is performed in T-175 flasks, and about <semantics>1×106<annotation encoding="application / x-tex">1 \times 10^6< / annotation>< / semantics> TILs suspended in 150 mL of media may be added to each T-175 flask. The TILs may be cultured in a 1 to 1 mixture of CM and AIM-V medium, supplemented with 3000 IU per mL of IL-2 and 30 ng per ml of anti-CD3. The T-175 flasks may be incubated at 37° C in 5% CO2.

In some embodiments, on day 7 cells from two T-175 flasks may be combined in a 3 L bag and 300 mL of AIM V with 5% human AB serum and 3000 IU per mL of IL-2 was added to the 300 ml of TIL suspension. The number of cells in each bag was counted every day or two and fresh media was added to keep the cell count between 0.5 and <semantics>2.0×106<annotation encoding="application / x-tex">2.0 \times 10^6< / annotation>< / semantics> cells / mL.

[00502] In an embodiment, the second expansion (which can include expansions referred to as REP, as well as those referred to in Step D of Figure 1) may be performed in 500 mL capacity gas permeable flasks with 100 cm gas-permeable silicon bottoms (G-Rex 100, commercially available from Wilson Wolf Manufacturing Corporation, New Brighton, MN, USA), <semantics>5×106<annotation encoding="application / x-tex">5 \times 10^6< / annotation>< / semantics> or <semantics>10×106<annotation encoding="application / x-tex">10 \times 10^6< / annotation>< / semantics> TIL may be cultured with PBMCs in 400 mL of 50 / 50 medium, supplemented with 5% human AB serum, 3000 IU per mL of IL-2 and 30 ng per ml of anti-CD3 (OKT3).

The TIL pellets may be re-suspended with 150 mL of fresh medium with 5% human AB serum, 3000 IU per mL of IL-2, and added back to the original G-Rex 100 flasks. When TIL are expanded serially in G-Rex 100 flasks, on day 7 the TIL in each G-Rex 100 may be suspended in the 300 mL of media present in each flask and the cell suspension may be divided into 3 100 mL aliquots that may be used to seed 3 G-Rex 100 flasks. Then 150 mL of AIM-V with 5% human AB serum and 3000 IU per mL of IL-2 may be added to each flask. The G-Rex 100 flasks may be incubated at 37° C in 5% CO2 and after 4 days 150 mL of AIM-V with 3000 IU per mL of IL- 2 may be added to each G-REX 100 flask. The cells may be harvested on day 14 of culture.

[00503] In an embodiment, the second expansion (including expansions referred to as REP) is performed in flasks with the bulk TILs being mixed with a 100- or 200-fold excess of inactivated feeder cells, 30 mg / mL OKT3 anti-CD3 antibody and 3000 IU / mL IL-2 in 150 ml media. In some embodiments, media replacement is done until the cells are transferred to an alternative growth chamber. In some embodiments, 2 / 3 of the media is replaced by respiration with fresh media. In some embodiments, alternative growth chambers include G-REX flasks and gas permeable containers as more fully discussed below.

[00504] In an embodiment, the second expansion (including expansions referred to as REP) is performed and further comprises a step wherein TILs are selected for superior tumor reactivity. Any selection method known in the art may be used. For example, the methods described in U.S. Patent Application Publication No. 2016 / 0010058 A1, may be used for selection of TILs for superior tumor reactivity.

[00505] Optionally, a cell viability assay can be performed after the second expansion (including expansions referred to as the REP expansion), using standard assays known in the art. For example, a trypan blue exclusion assay can be done on a sample of the bulk TILs, which selectively labels dead cells and allows a viability assessment. In some embodiments, TIL samples can be counted and viability determined using a Cellometer K2 automated cell counter (Nexcelor Bioscience, Lawrence, MA). In some embodiments, viability is determined according to the standard Cellometer K2 Image Cytometer Automatic Cell Counter protocol.

[00506] In some embodiments, the second expansion (including expansions referred to as REP) of TIL can be performed using T-175 flasks and gas-permeable bags as previously described (Tran KQ, Zhou J, Durflinger KH, et al., 2008, J Immunother., 31:742–751, and Dudley ME, Wunderlich JR, Shelton TE, et al. 2003, J Immunother., 26:332–342) or gas-permeable G-Rex flasks. In some embodiments, the second expansion is performed using flasks. In some embodiments, the second expansion is performed using gas-permeable G-Rex flasks. In some embodiments, the second expansion is performed in T-175 flasks, and about <semantics>1×106<annotation encoding="application / x-tex">1 \times 10^6< / annotation>< / semantics> TIL are suspended in about 150 mL of media and this is added to each T-175 flask. The TIL are cultured with irradiated (50 Gy) allogeneic PBMC as "feeder" cells at a ratio of 1 to 100 and the cells were cultured in a 1 to 1 mixture of CM and AIM-V medium (50 / 50 medium), supplemented with 3000 IU / mL of IL-2 and 30 ng / mL of anti-CD3. The T-175 flasks are incubated at 37°C in 5% CO2. In some embodiments, half the media is changed on day 5 using 50 / 50 medium with 3000 IU / mL of IL-2. In some embodiments, on day 7, cells from 2 T-175 flasks are combined in a 3 L bag and 300 mL of AIM-V with 5% human AB serum and 3000 IU / mL of IL-2 is added to the 300 mL of TIL suspension. The number of cells in each bag can be counted every day or two and fresh media can be added to keep the cell count between about 0.5 and about <semantics>2.0×106<annotation encoding="application / x-tex">2.0 \times 10^6< / annotation>< / semantics> cells / mL.

[00507] In some embodiments, the second expansion (including expansions referred to as REP) are performed in 500 mL capacity flasks with 100 cm2 gas-permeable silicon bottoms (G-Rex 100, Wilson Wolf) (Fig. 1), about <semantics>5×106<annotation encoding="application / x-tex">5 \times 10^6< / annotation>< / semantics> or <semantics>10×106<annotation encoding="application / x-tex">10 \times 10^6< / annotation>< / semantics> TIL are cultured with irradiated allogeneic PBMC at a ratio of 1 to 100 in 400 mL of 50 / 50 medium, supplemented with 3000 IU / mL of IL- 2 and 30 ng / mL of anti-CD3. The G-Rex 100 flasks are incubated at 37°C in 5% CO2. In some embodiments, on day 5, 250mL of supernatant is removed and placed into centrifuge bottles and centrifuged at 1500 rpm (491g) for 10 minutes. The TIL pellets can then be resuspended with 150 mL of fresh 50 / 50 medium with 3000 IU / mL of IL-2 and added back to the original G-Rex 100 flasks. In embodiments where TILs are expanded serially in G-Rex 100 flasks, on day 7 the TIL in each G-Rex 100 are suspended in the 300 mL of media present in each flask and the cell suspension was divided into three 100 mL aliquots that are used to seed 3 G-Rex 100 flasks. Then 150 mL of AIM-V with 5% human AB serum and 3000 IU / mL of IL-2 is added to each flask. The G-Rex 100 flasks are incubated at 37°C in 5% CO2 and after 4 days 150 mL of AIM- V with 3000 IU / mL of IL-2 is added to each G-Rex 100 flask. The cells are harvested on day 14 of culture.

[00508] The diverse antigen receptors of T and B lymphocytes are produced by somatic recombination of a limited, but large number of gene segments. These gene segments: V (variable), D (diversity), J (joining), and C (constant), determine the binding specificity and downstream applications of immunoglobulins and T-cell receptors (TCRs). The present invention provides a method for generating TILs which exhibit and increase the T-cell repertoire diversity. In some embodiments, the TILs obtained by the present method exhibit an increase in the T-cell repertoire diversity. In some embodiments, the TILs obtained in the second expansion exhibit an increase in the T-cell repertoire diversity. In some embodiments, the increase in diversity is an increase in the immunoglobulin diversity and / or the T-cell receptor diversity. In some embodiments, the diversity is in the immunoglobulin is in the immunoglobulin heavy chain. In some embodiments, the diversity is in the immunoglobulin is in the immunoglobulin light chain. In some embodiments, the diversity is in the T-cell receptor. In some embodiments, the diversity is in one of the T-cell receptors selected from the group consisting of alpha, beta, gamma, and delta receptors. In some embodiments, there is an increase in the expression of T- cell receptor (TCR) alpha and / or beta. In some embodiments, there is an increase in the expression of T-cell receptor (TCR) alpha. In some embodiments, there is an increase in the expression of T-cell receptor (TCR) beta. In some embodiments, there is an increase in the expression of TCRab (i.e., TCR<semantics>α / β<annotation encoding="application / x-tex">\alpha / \beta< / annotation>< / semantics>).

[00509] In some embodiments, the second expansion culture medium (e.g., sometimes referred to as CM2 or the second cell culture medium), comprises IL-2, OKT-3, as well as the antigen- presenting feeder cells (APCs), as discussed in more detail below.

[00510] In some embodiments, the second expansion, for example, Step D according to Figure 1, is performed in a closed system bioreactor. In some embodiments, a closed system is employed for the TIL expansion, as described herein. In some embodiments, a single bioreactor is employed. In some embodiments, the single bioreactor employed is for example a G-REX -10 or a G-REX-100. In some embodiments, the closed system bioreactor is a single bioreactor. Feeder Cells and Antigen Presenting Cells

[00511] In an embodiment, the second expansion procedures described herein (for example including expansion such as those described in Step D from Figure 1, as well as those referred to as REP) require an excess of feeder cells during REP TIL expansion and / or during the second expansion. In many embodiments, the feeder cells are peripheral blood mononuclear cells (PBMCs) obtained from standard whole blood units from healthy blood donors. The PBMCs are obtained using standard methods such as Ficoll-Paque gradient separation, see, e.g. "Isolation of mononuclear cells: Methodology and Application", GE Life Sciences technical publication 18- 1152-69-AE, available at https: / / us.vwr.com / assetsvc / asset / en US / id / 16286835 / contents.

[00512] In general, the allogenic PBMCs are inactivated, either via irradiation or heat treatment, and used in the REP procedures, as described in the examples, which provides an exemplary protocol for evaluating the replication incompetence of irradiate allogeneic PBMCs.

[00513] In some embodiments, PBMCs are considered replication incompetent and accepted for use in the TIL expansion procedures described herein if the total number of viable cells on day 14 is less than the initial viable cell number put into culture on day 0 of the REP and / or day 0 of the second expansion (i.e., the start day of the second expansion).

[00514] In some embodiments, PBMCs are considered replication incompetent and accepted for use in the TIL expansion procedures described herein if the total number of viable cells, cultured in the presence of OKT3 and IL-2, on day 7 and day 14 has not increased from the initial viable cell number put into culture on day 0 of the REP and / or day 0 of the second expansion (i.e., the start day of the second expansion). In some embodiments, the PBMCs are cultured in the presence of 30 ng / ml OKT3 antibody and 3000 IU / ml IL-2.

[00515] In some embodiments, PBMCs are considered replication incompetent and accepted for use in the TIL expansion procedures described herein if the total number of viable cells, cultured in the presence of OKT3 and IL-2, on day 7 and day 14 has not increased from the initial viable cell number put into culture on day 0 of the REP and / or day 0 of the second expansion (i.e., the start day of the second expansion). In some embodiments, the PBMCs are cultured in the presence of 5 to 60 ng / ml OKT3 antibody and 1000-6000 IU / ml IL-2. In some embodiments, the PBMCs are cultured in the presence of 10 to 50 ng / ml OKT3 antibody and 2000-5000 IU / ml IL- 2. In some embodiments, the PBMCs are cultured in the presence of 20 to 40 ng / ml OKT3 antibody and 2000-4000 IU / ml IL-2. In some embodiments, the PBMCs are cultured in the presence of 25 to 35 ng / ml OKT3 antibody and 2500-3500 IU / ml IL-2.

[00516] In some embodiments, the antigen-presenting feeder cells are PBMCs. In some embodiments, the antigen-presenting feeder cells are artificial antigen-presenting feeder cells. In an embodiment, the ratio of TILs to antigen-presenting feeder cells in the second expansion is about 1 to 25, about 1 to 50, about 1 to 100, about 1 to 125, about 1 to 150, about 1 to 175, about 1 to 200, about 1 to 225, about 1 to 250, about 1 to 275, about 1 to 300, about 1 to 325, about 1 to 350, about 1 to 375, about 1 to 400, or about 1 to 500. In an embodiment, the ratio of TILs to antigen-presenting feeder cells in the second expansion is between 1 to 50 and 1 to 300. In an embodiment, the ratio of TILs to antigen-presenting feeder cells in the second expansion is between 1 to 100 and 1 to 200.

[00517] In an embodiment, the second expansion procedures described herein require a ratio of about <semantics>2.5×109<annotation encoding="application / x-tex">2.5 \times 10^9< / annotation>< / semantics> feeder cells to about <semantics>100×106<annotation encoding="application / x-tex">100 \times 10^6< / annotation>< / semantics> TILs. In another embodiment, the second expansion procedures described herein require a ratio of about <semantics>2.5×109<annotation encoding="application / x-tex">2.5 \times 10^9< / annotation>< / semantics> feeder cells to about 50 <semantics>×<annotation encoding="application / x-tex">\times< / annotation>< / semantics> 106 TILs. In yet another embodiment, the second expansion procedures described herein require about <semantics>2.5×109<annotation encoding="application / x-tex">2.5 \times 10^9< / annotation>< / semantics> feeder cells to about <semantics>25×106<annotation encoding="application / x-tex">25 \times 10^6< / annotation>< / semantics> TILs.

[00518] In an embodiment, the second expansion procedures described herein require an excess of feeder cells during the second expansion. In many embodiments, the feeder cells are peripheral blood mononuclear cells (PBMCs) obtained from standard whole blood units from healthy blood donors. The PBMCs are obtained using standard methods such as Ficoll-Paque gradient separation. In an embodiment, artificial antigen-presenting (aAPC) cells are used in place of PBMCs.

[00519] In general, the allogenic PBMCs are inactivated, either via irradiation or heat treatment, and used in the TIL expansion procedures described herein, including the exemplary procedures described in the figures and examples.

[00520] In an embodiment, artificial antigen presenting cells are used in the second expansion as a replacement for, or in combination with, PBMCs. Cytokines

[00521] The TIL expansion methods described herein generally use culture media with high doses of a cytokine, in particular IL-2, as is known in the art.

[00522] Alternatively, using combinations of cytokines for the rapid expansion and or second expansion of TILs is additionally possible, with combinations of two or more of IL-2, IL-15 and IL-21 as is generally outlined in International Publication No. WO 2015 / 189356 and W International Publication No. WO 2015 / 189357. Thus, possible combinations include IL-2 and IL-15, IL-2 and IL-21, IL-15 and IL- 21 and IL-2, IL-15 and IL-21, with the latter finding particular use in many embodiments. The use of combinations of cytokines specifically favors the generation of lymphocytes, and in particular T-cells as described therein. Step E: Harvest TILs

[00523] After the second expansion step, cells can be harvested. In some embodiments the TILs are harvested after one, two, three, four or more expansion steps, for example as provided in Figure 1. In some embodiments the TILs are harvested after two expansion steps, for example as provided in Figure 1.

[00524] TILs can be harvested in any appropriate and sterile manner, including for example by centrifugation. Methods for TIL harvesting are well known in the art and any such know methods can be employed with the present process. In some embodiments, TILS are harvest using an automated system.

[00525] Cell harvesters and / or cell processing systems are commercially available from a variety of sources, including, for example, Fresenius Kabi, Tomtec Life Science, Perkin Elmer, and Inotech Biosystems International, Inc. Any cell based harvester can be employed with the present methods. In some embodiments, the cell harvester and / or cell processing systems is a membrane-based cell harvester. In some embodiments, cell harvesting is via a cell processing system, such as the LOVO system (manufactured by Fresenius Kabi). The term "LOVO cell processing system" also refers to any instrument or device manufactured by any vendor that can pump a solution comprising cells through a membrane or filter such as a spinning membrane or spinning filter in a sterile and / or closed system environment, allowing for continuous flow and cell processing to remove supernatant or cell culture media without pelletization. In some embodiments, the cell harvester and / or cell processing system can perform cell separation, washing, fluid-exchange, concentration, and / or other cell processing steps in a closed, sterile system.

[00526] In some embodiments, the harvest, for example, Step E according to Figure 1, is performed from a closed system bioreactor. In some embodiments, a closed system is employed for the TIL expansion, as described herein. In some embodiments, a single bioreactor is employed. In some embodiments, the single bioreactor employed is for example a G-REX -10 or a G-REX -100. In some embodiments, the closed system bioreactor is a single bioreactor.
