[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to U.S. Provisional Patent No. 63 / 387,919, filed December 16, 2022, U.S. Provisional Patent No. 63 / 353,832, filed June 20, 2022, and U.S. Provisional Patent No. 63 / 340,446, filed May 10, 2022, all of which are incorporated by reference in their entireties herein. [Background technology]
[0002] The treatment of bulky refractory cancers using adoptive autologous transfer of tumor infiltrating lymphocytes (TILs) represents a powerful approach to the treatment of patients with poor prognosis. Gattinoni, et al., Nat. Rev. Immunol. 2006, 6, 383-393. TILs are dominated by T cells, and IL-2-based TIL expansion followed by the "rapid expansion process" (REP) has become the preferred method of TIL expansion due to 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. Many approaches to improve response to TIL therapy in melanoma and extend TIL therapy to other tumor types have met with limited success, and the field remains challenging. Goff, et al., J.Clin.Oncol.2016,34,2389-97; Dudley, et al., J.Clin.Oncol.2008,26,5233-39; Rosenberg,et al., Clin.Cancer Res.2011,17,4550-57. Combination studies with single immune checkpoint inhibitors have also been described, but further studies are ongoing and additional treatment approaches are needed (Kverneland,et al.,Oncotarget,2020,11(22),2092-2105).
[0003] The current TIL regimen platform relies on the administration of nonmyeloablative lymphodepletion (NMALD) followed by TIL cell therapy and then a short course of high-dose IL-2 (aldesleukin).
[0004] Pre-TIL NMALD serves to i) reduce lymphocyte populations and provide an environment supportive of the incoming TIL cell therapy product for optimal expansion / survival, and ii) optimize the tumor microenvironment by reducing Tregs and MDSCs that may contribute to the inhibitory signaling of neoantigen-reactive TILs.
[0005] IL-2 (aldesleukin) following TIL serves to further support the survival and proliferation of the infused TIL cell product.
[0006] Given the current relatively high doses of cyclophosphamide in NMALD and the safety profile of high-dose IL-2 (aldesleukin), improved methods of using TILs to treat cancer while reducing patient exposure to chemotherapeutic agents during NMALD with high-dose IL-2 before and / or after TIL infusion are needed.

[0501] The term "IL-15R agonist" (also referred to herein as "IL-15 agonist") refers to a molecule that activates the IL-15 signaling pathway by binding to the IL-15 receptor (IL-15R) beta and common gamma (γC) subunits. IL-15 is presented in a complex with the membrane-bound α subunit of the IL-15 receptor (IL-15Rα) on the surface of dendritic cells or other cells, and this complex functions through a transpresentation mechanism that interacts with IL-15R beta and gamma subunits expressed on NK, NKT or T cells. See Stonier and Schluns, Immunol Lett. 2010, 127, 85-92, the disclosure of which is incorporated herein by reference. IL-15 agonists are described, for example, in Wu, J Mol Genet Med. 2013, 7, 85, the disclosure of which is incorporated herein by reference. In some embodiments, the IL-15R agonist can be a recombinant IL-15 molecule. In some embodiments, the IL-15R agonist can be a mimic of the IL-15 / IL-15Rα complex presented on the cell surface, e.g., a heterodimeric complex or fusion protein comprising an IL-15 wild-type or mutant (e.g., N72D, D30N, E64Q, N65D) molecule and a partial or extracellular domain of IL-15Rα, e.g., soluble IL-15Rα, sushi domain of IL-15Rα, etc., optionally linked to one or more Fc domains. In some embodiments, the IL-15R agonist can be a modified IL-15 molecule, e.g., an IL-15 mutant molecule (e.g., N72D, D30N, E64Q, N65D), IL-15 with site-specific glycosolation(s), etc., with improved characteristics, e.g., extended half-life, increased affinity for IL-15R, etc.
[0502] When an "antitumor effective amount," "tumor inhibiting effective amount," or "therapeutic amount" is indicated, the exact amount of the composition of the present invention to be administered can be determined by a physician, taking into account individual differences in the age, weight, tumor size, extent of infection or metastasis, and health status of the patient (subject). Generally, the tumor-infiltrating lymphocytes (e.g., secondary TILs or genetically modified cytotoxic lymphocytes) described herein are administered at a concentration of 10 per kg of body weight. 4 ~10 11 Cells (e.g., 10 per kg body weight) 5 ~10 6 , 10 5 ~10 10 , 10 5 ~10 11 , 10 6 ~10 10 , 10 6 ~10 11 , 10 7 ~10 11 , 10 7 ~10 10 , 10 8 ~10 11 , 10 8 ~10 10 , 10 9 ~10 11 , or 10 9 ~10 10 It may be stated that the TIL (optionally including genetically modified cytotoxic lymphocytes) compositions may be administered in doses of 100-200 mg / kg / day (including all integer values within those ranges). TIL (optionally including genetically engineered TIL) compositions may also be administered multiple times at these doses. TIL (optionally including genetically engineered TIL) may be administered by using injection techniques commonly known in immunotherapy (see, e.g., Rosenberg, et al., New Eng. J. of Med. 1988, 319, 1676). Optimal dosages and treatment regimens for a particular patient may be readily determined by one skilled in the medical arts by monitoring the patient for signs of disease and adjusting treatment accordingly.
[0503] The term "hematological malignancies", "blood system malignancies" or terms of related meaning refer to cancers and tumors of mammalian hematopoietic and lymphatic tissues, including but not limited to blood, bone marrow, lymph nodes, and lymphatic tissues. Hematological malignancies are also referred to as "liquid tumors". Hematological malignancies may include, but are not limited to, acute lymphoblastic leukemia (ALL), chronic lymphocytic lymphoma (CLL), small lymphocytic lymphoma (SLL), acute myeloid leukemia (AML), chronic myelogenous leukemia (CML), multiple myeloma, acute monocytic leukemia (AMoL), Hodgkin's lymphoma, and non-Hodgkin's lymphoma. The term "B-cell hematological malignancies" refers to hematological malignancies affecting B cells.
[0504] 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, leukemia, myeloma, and lymphoma, as well as other hematological malignancies. TILs obtained from liquid tumors may also be referred to herein as bone marrow infiltrating lymphocytes (MILs). TILs obtained from liquid tumors, including those circulating in peripheral blood, may also be referred to herein as PBLs. The terms MILs, TILs, and PBLs are used interchangeably herein and differ only based on the tissue type from which the cells are derived.
[0505] The term "microenvironment" as used herein may refer to the solid or hematological tumor microenvironment as a whole, or to individual subsets of cells within the microenvironment. As used herein, tumor microenvironment refers to a complex mixture of "cells, soluble factors, signaling molecules, extracellular matrix, and mechanical cues that promote neoplastic transformation, support tumor growth and invasion, protect tumors from host immunity, foster therapeutic resistance, and provide a niche for successful and successful metastasis," 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 due to immunosuppression by the microenvironment.
[0506] In some embodiments, the invention includes a method of treating cancer with a TIL population, where the patient is pretreated with non-myeloablative chemotherapy prior to infusion of TILs according to the invention. In some embodiments, a TIL population may be provided, where the patient is pretreated with non-myeloablative chemotherapy prior to infusion of TILs according to the invention. In some embodiments, the non-myeloablative chemotherapy is cyclophosphamide 60 mg / kg / day for 2 days (27 and 26 days prior to TIL infusion) and fludarabine 25 mg / m2 / day for 5 days (27-23 days prior to TIL infusion). In some embodiments, after non-myeloablative chemotherapy and TIL infusion according to the invention (day 0), the patient receives an intravenous infusion of IL-2 at 720,000 IU / kg every 8 hours until physiological tolerance.
[0507] Experimental findings indicate that lymphodepletion prior to adoptive transfer of tumor-specific T lymphocytes plays an important role in enhancing therapeutic efficacy by eliminating regulatory T cells and competing elements of the immune system ("cytokine sinks"). Thus, some embodiments of the present invention utilize a lymphodepletion step (sometimes referred to as "immunosuppressive conditioning") on patients prior to introducing the TILs of the present invention.
[0508] The term "effective amount" or "therapeutically effective amount" refers to an amount of a compound or combination of compounds described herein that is sufficient to achieve the intended use, including but not limited to disease treatment. Therapeutically effective amounts may vary depending on the intended use (in vitro or in vivo), or the subject and condition being treated (e.g., the subject's weight, age, and sex), the severity of the condition, or the method of administration. The term also applies to a dose that induces a particular response in target cells (e.g., reduced platelet adhesion and / or cell migration). The particular dose will vary depending on the particular compound selected, the dosing regimen to be followed, whether the compound is administered in combination with other compounds, the timing of administration, the tissue to which it is administered, and the physical delivery system in which the compound is delivered.
[0509] The terms "treatment", "treating", "treating" and the like refer to obtaining a desired pharmacological and / or physiological effect. The effect may be prophylactic in terms of completely or partially preventing the disease or condition, and / or therapeutic in terms of partially or completely curing the disease and / or side effects caused by the disease. As used herein, "treatment" encompasses any treatment of disease in a mammal, particularly a human, and includes (a) preventing the disease from occurring in a subject who may be susceptible to the disease but has not yet been diagnosed as having the disease, (b) inhibiting the disease, i.e., arresting its onset or progression, and (c) relieving the disease, i.e., causing regression of the disease and / or relieving one or more disease symptoms. "Treatment" is also intended to encompass the delivery of an agent to provide a pharmacological effect even in the absence of a disease or condition. For example, "treatment" encompasses the delivery of a composition capable of eliciting an immune response or conferring immunity in the absence of a pathology, e.g., in the case of a vaccine.
[0510] As used herein, the term "immune checkpoint inhibitor (ICI)" has its general meaning in the art and refers to any compound that inhibits the function of immune inhibitory checkpoint proteins. As used herein, the term "immune checkpoint protein" has its general meaning in the art and refers to a molecule expressed by T cells that either increases (stimulatory checkpoint molecules) or decreases (inhibitory checkpoint molecules) signals. Immune checkpoint molecules are recognized in the art as constituting elements of immune checkpoint pathways similar to the CTLA-4 and PD-1 dependent pathways (see, e.g., Pardoll, 2012. Nature Rev Cancer 12:252-264; Mellman et al., 2011. Nature 480:480- 489). Examples of inhibitory checkpoint molecules include A2AR, B7-H3, B7-H4, CD277, IDO, KIR, VISTA, PD-1, CTLA-4, LAG-3, HAVCR2 (TIM-3), Cish, TGFβ, PKA, CBL-B, PPP2CA, PPP2CB, PTPN6, PTPN22, PDCD1, BTLA, CD160, TIGIT, TET2, BAFF (BR3), CD96, CRTAM, LAIR1, SIGLEC7, SIGLEC9, CD244, TNFRSF10B, These include TNFRSF10A, CASP8, CASP10, CASP3, CASP6, CASP7, FADD, FAS, SMAD2, SMAD3, SMAD4, SMAD10, SKI, SKIL, TGIF1, IL10RA, IL10RB, HMOX2, IL6R, IL6ST, EIF2AK4, CSK, PAG1, SIT1, FOXP3, PRDM1, BATF, GUCY1A2, GUCY1A3, GUCY1B2, GUCY1B3, TOX, SOCS1, ANKRD11, and BCOR. For example, immune checkpoint genes that may be silenced or inhibited in the TILs of the present invention may be selected from the group including PD-1, CTLA-4, LAG-3, TIM-3, Cish, CBL-B, TIGIT, TET2, TGFβ, and PKA.BAFF(BR3) is described in Bloom, et al., J. Immunother., 2018, in press. According to another embodiment, the immune checkpoint genes that may be silenced or inhibited in the TILs of the present invention may be selected from the group including PD-1, LAG-3, TIM-3, CTLA-4, TIGIT, TET2, CISH, TGFβR2, PRA, CBLB, BAFF(BR3), and combinations thereof.
[0511] Inhibition includes reduction and complete blockage of function. Preferred immune checkpoint inhibitors are antibodies that specifically recognize immune checkpoint proteins. Several immune checkpoint inhibitors are known, and as well as these known immune checkpoint protein inhibitors, alternative immune checkpoint inhibitors may be developed in the (near) future. Immune checkpoint inhibitors include peptides, antibodies, nucleic acid molecules, and small molecules.
[0512] "Non-myeloablative chemotherapy", "non-myeloablative lymphodepletion", "NMALD", "NMA LD", "NMA-LD", and any variants of the foregoing, are used interchangeably to refer to chemotherapy regimens designed to avoid depletion of a patient's myeloid immune cells while depleting the patient's lymphoid immune cells. Typically, a patient undergoes a course of non-myeloablative chemotherapy prior to administering tumor-infiltrating lymphocytes to the patient, as described herein.
[0513] The term "heterologous" when used in reference to a portion of a nucleic acid or protein indicates that the nucleic acid or protein comprises two or more subsequences that are not found in the same relationship to each other in nature. For example, a nucleic acid is typically produced recombinantly and has two or more sequences from unrelated genes arranged to create a new functional nucleic acid, such as a promoter from one source and a coding region from another source, or a coding region from a different source. Similarly, a heterologous protein indicates that the protein comprises two or more subsequences that are not found in the same relationship to each other in nature (e.g., a fusion protein).
[0514] The terms "sequence identity," "percent identity," and "percent sequence identity" (or their synonyms, e.g., "99% identical") 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 certain percentage of the same nucleotides or amino acid residues when compared and aligned for maximum correspondence (introducing gaps, if necessary), without considering any conservative amino acid substitutions as part of the sequence identity. Percent identity can be measured using sequence comparison software or algorithms or by visual inspection. Various algorithms and software that can be used to obtain alignment of amino acid or nucleotide sequences are known in the art. Programs suitable for determining percent sequence identity include, for example, the BLAST suite of programs available from the BLAST website of the U.S. Government's National Center for Biotechnology Information. Comparison between two sequences can be performed using either the BLASTN or BLASTP algorithm. BLASTN is used to compare nucleic acid sequences, and BLASTP is used to compare amino acid sequences. ALIGN, available from DNASTAR, ALIGN-2 (Genentech, South San Francisco, California), or MegAlign are additional publicly available software programs that can be used to align sequences. Those skilled in the art can determine the appropriate parameters for maximum alignment according to the particular alignment software. In certain embodiments, the default parameters of the alignment software are used.
[0515] As used herein, the term "variant" includes, but is not limited to, an antibody or fusion protein that comprises an amino acid sequence that differs from the amino acid sequence of a reference antibody by one or more substitutions, deletions, and / or additions at specific positions within or adjacent to the amino acid sequence of the reference antibody. A variant may include one or more conservative substitutions in its amino acid sequence compared to the amino acid sequence of the reference antibody. Conservative substitutions may include, for example, substitutions of similarly charged or uncharged amino acids. A variant retains the ability of the reference antibody to specifically bind to the antigen. The term variant also includes pegylated antibodies or proteins.
[0516] As used herein, "tumor infiltrating lymphocytes" or "TILs" refers to a population of cells that are initially acquired as leukocytes that have left the bloodstream of a subject and migrated to a tumor. TILs include CD8 + Cytotoxic T cells (lymphocytes), Th1 and Th17 CD4 + These include, but are not limited to, T cells, natural killer cells, dendritic cells, and M1 macrophages. TILs include both primary and secondary TILs. "Primary TILs" are those obtained from a patient tissue sample as outlined herein (sometimes referred to as "freshly harvested"), and "secondary TILs" are any TIL cell populations expanded or propagated as discussed herein, including, but not limited to, bulk TILs, expanded TILs ("REP TILs"), and "reREP TILs" as discussed herein. reREP TILs can include, for example, a second expanded TIL or a second additional expanded TIL (e.g., such as those described in step D of FIG. 8, including TILs referred to as reREP TILs).
[0517] TILs can generally be either biochemically defined using cell surface markers or functionally defined by their ability to infiltrate tumors and achieve therapy. TILs can generally be classified by expression of one or more of the following biomarkers: CD4, CD8, TCRαβ, 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 patients. TILs can be further characterized by potency, e.g., TILs can be considered potent if interferon (IFN) release is greater than about 50 pg / mL, greater than about 100 pg / mL, greater than about 150 pg / mL, or greater than about 200 pg / mL. For example, TILs can be considered potent if interferon (IFNγ) release is greater than about 50 pg / mL, greater than about 100 pg / mL, greater than about 150 pg / mL, or greater than about 200 pg / mL, greater than about 300 pg / mL, greater than about 400 pg / mL, greater than about 500 pg / mL, greater than about 600 pg / mL, greater than about 700 pg / mL, greater than about 800 pg / mL, greater than about 900 pg / mL, greater than about 1000 pg / mL.
[0518] The term "deoxyribonucleotide" encompasses natural and synthetic, unmodified and modified deoxyribonucleotides. Modifications include changes to the sugar moiety, the base moiety, and / or the linkages between deoxyribonucleotides in an oligonucleotide.
[0519] The term "RNA" defines a molecule that contains at least one ribonucleotide residue. The term "ribonucleotide" defines a nucleotide that has a hydroxyl group at the 2' position of the bD-ribofuranose moiety. The term RNA includes double-stranded RNA, single-stranded RNA, isolated RNA such as partially purified RNA, essentially pure RNA, synthetic RNA, recombinantly produced RNA, and altered RNA that differs from naturally occurring RNA by the addition, deletion, substitution, and / or alteration of one or more nucleotides. The nucleotides of the RNA molecules described herein may also include non-naturally occurring nucleotides or non-standard nucleotides such as chemically synthesized nucleotides or deoxynucleotides. These altered RNAs may be referred to as analogs or analogs of naturally occurring RNA.
[0520] The term "pharmaceutically acceptable carrier" or "pharmaceutically acceptable excipient" is intended to include any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents, and inactive ingredients. The use of such pharmaceutically acceptable carriers or pharmaceutically acceptable excipients for active pharmaceutical ingredients is well known in the art. 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 present invention is contemplated. Additional active pharmaceutical ingredients, such as other drugs, can also be incorporated into the compositions and methods described.
[0521] The terms "about" and "approximately" mean within a statistically significant range of values. Such ranges may be within an order of magnitude, preferably within 50%, more preferably within 20%, even more preferably within 10%, and even more preferably within 5% of a given value or range. The allowable deviation encompassed by the terms "about" or "approximately" depends on the particular system under study and can be readily understood by one of ordinary skill in the art. Furthermore, as used herein, the terms "about" and "approximately" mean that dimensions, sizes, formulations, parameters, shapes, and other quantities and features are not, and need not be, precise, but may be approximate and / or may be greater or smaller, as appropriate, reflecting tolerances, conversion factors, rounding, measurement errors, and the like, and other factors known to those of ordinary skill in the art. In general, a dimension, size, formulation, parameter, shape, or other quantity or feature is "about" or "approximately" whether or not it is expressly stated as such. It should be noted that embodiments of very different sizes, shapes, and dimensions may employ the described arrangements.
[0522] When used in the appended claims, the transitional terms "comprising," "consisting essentially of," and "consisting of" define the claim in its original and amended form with respect to whether additional unrecited claim elements or steps, if any, are excluded from the claim. The term "comprising" is intended to be inclusive or open-ended and does not exclude any additional unrecited elements, methods, steps, or materials. The term "consisting of" excludes any element, step, or material other than those specified in the claim, and in the latter case, also excludes impurities normally associated with the specified material(s). The term "consisting essentially of" limits the claim to the specified element, step, or material(s) and does not materially affect the basic and novel feature(s) of the claimed invention. All compositions, methods, and kits described herein embodying the present invention may be more specifically defined in alternative embodiments by any of the transitional terms "comprising," "consisting essentially of," and "consisting of."
[0523] The terms "antibody" and its plural "antibodies" refer to whole immunoglobulins and to any antigen-binding fragment ("antigen-binding portion") or single chains thereof. "Antibody" also refers to a glycoprotein comprising at least two heavy (H) chains and two light (L) chains interconnected by disulfide bonds, or antigen-binding portions thereof. Each heavy chain contains a heavy chain variable region (referred to herein as V H Each light chain is composed of a light chain variable region (abbreviated herein as V) and a heavy chain constant region. The heavy chain constant region is composed of three domains, CH1, CH2, and CH3. Each light chain is composed of a light chain variable region (abbreviated herein as V L The light chain constant region is composed of one domain, C L The V of the antibody H and V L The regions can be further subdivided into regions of hypervariability, termed complementarity determining regions (CDRs) or hypervariable regions (HVRs), which may be interspersed with more conserved regions, termed framework regions (FRs). H and V Lis 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 binding domains that interact with one or more antigen epitopes. The constant region of the antibody 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.
[0524] The term "antigen" refers to a substance that induces an immune response. In some embodiments, an antigen is a molecule that can be bound by an antibody or TCR when presented by a major histocompatibility complex (MHC) molecule. The term "antigen" as used herein also encompasses T cell epitopes. An antigen can additionally be recognized by the immune system. In some embodiments, an antigen can induce a humoral or cellular immune response, leading to the activation of B and / or T lymphocytes. In some cases, this may require that the antigen contains or is bound to a Th cell epitope. An antigen may also have one or more epitopes (e.g., B- and T-epitopes). In some embodiments, an antigen preferably reacts with a corresponding antibody or TCR, typically in a highly specific and selective manner, and not with a large number of other antibodies or TCRs that may be induced by other antigens.
[0525] The terms "monoclonal antibody", "mAb", "monoclonal antibody composition", or their plurals, refer to a preparation of antibody molecules of single molecular composition. A monoclonal antibody composition exhibits a single binding specificity and affinity for a particular epitope. Monoclonal antibodies specific for a particular receptor can be made using knowledge and techniques in the art by injecting a test subject with an appropriate antigen and then isolating hybridomas expressing antibodies with the desired sequence or functional characteristics. DNA encoding the monoclonal antibodies is readily isolated and sequenced using conventional procedures (e.g., by using oligonucleotide probes that can specifically bind to genes encoding the heavy and light chains of the monoclonal antibody). Hybridoma cells serve as a preferred source of such DNA. Once isolated, the DNA can be placed into an expression vector and then transfected into host cells, such as E. coli cells, monkey COS cells, Chinese hamster ovary (CHO) cells, or myeloma cells that do not produce immunoglobulin proteins, to obtain the synthesis of the monoclonal antibody in the recombinant host cells. Recombinant production of antibodies is described in more detail below.
[0526] As used herein, the term "antigen-binding portion" or "antigen-binding fragment" of an antibody (or simply "antibody portion" or "fragment") refers to one or more fragments of an antibody that retain the ability to specifically bind to an antigen. 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 by the term "antigen-binding portion" of an antibody include: (i) V L , V H , C L (ii) a F(ab′)2 fragment, which is a bivalent fragment comprising two Fab fragments linked by disulfide bridges at the hinge region; and (iii) a V H and an Fd fragment consisting of the CH1 domain, (iv) a V of a single arm of an antibody. L and V H (v) an Fv fragment consisting of a V H or VL The Fv fragment includes two domains, the V domain and the V domain. L and V H Although the V L and V H The regions may be joined by synthetic linkers that allow them to be made into a single protein chain that pairs to form a monovalent molecule known as a 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 by the term "antigen-binding portion" or "antigen-binding fragment" of an antibody. These antibody fragments are obtained using conventional techniques known to those of skill in the art, and the fragments are screened for utility in the same manner as intact antibodies. In some embodiments, the scFv protein domain is a V H Part and V L The scFv molecule comprises a V L If the domain is the N-terminal portion of an scFv molecule, then V L -LV H , or V H If the domain is the N-terminal portion of an scFv molecule, then V H -LV L Methods for producing scFv molecules and designing suitable peptide linkers are described in U.S. Pat. No. 4,704,692, U.S. Pat. No. 4,946,778, R. Raag and M. Whitlow, "Single Chain Fvs." FASEB Vol 9:73-80 (1995), and RE Bird and BW Walker, Single Chain Antibody Variable Regions, TIBTECH, Vol 9:132-137 (1991), the disclosures of which are incorporated herein by reference.
[0527] 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 is also 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.
[0528] The term "human monoclonal antibody" refers to antibodies displaying a single binding specificity having variable regions in which both the framework and CDR regions are derived from human germline immunoglobulin sequences. In some embodiments, human monoclonal antibodies are produced by a hybridoma comprising B cells obtained from a transgenic non-human animal, e.g., a transgenic mouse, whose genome comprises human heavy chain and light chain transgenes fused to an immortalized cell.
[0529] 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 animals (such as mice) that are transgenic or transchromosomal for human immunoglobulin genes or hybridomas prepared therefrom (described further below), (b) antibodies isolated from host cells transformed to express human antibodies, e.g., from transfectomas, (c) antibodies isolated from recombinant combinatorial human antibody libraries, and (d) antibodies prepared, expressed, created, or isolated by any other means, including splicing 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. However, in certain embodiments, such recombinant human antibodies may be subjected to in vitro mutagenesis (or, when animals transgenic for human Ig sequences are used, in vivo somatic mutagenesis) to thereby improve the V and V sequences of the recombinant antibodies. H and V L The amino acid sequence of the region is human germline V H and V L These are sequences that are derived from and related to sequences, but may not exist naturally within the human antibody germline repertoire in vivo.
[0530] As used herein, "isotype" refers to the antibody class (e.g., IgM or IgG1) that is encoded by heavy chain constant region genes.
[0531] The phrases "an antibody that recognizes an antigen" and "an antibody specific for an antigen" are used interchangeably herein with the term "an antibody that specifically binds to an antigen."
[0532] The term "human antibody derivative" refers to any modified form of a human antibody, including a conjugate of the antibody with another active pharmaceutical ingredient or antibody. The term "conjugate," "antibody drug conjugate," "ADC," or "immunoconjugate" refers to an antibody or fragment thereof conjugated to another therapeutic moiety, which can be conjugated to the antibodies described herein using methods available in the art.
[0533] The terms "humanized antibody," "humanized antibodies," and "humanization" are intended to refer to an antibody in which CDR sequences derived from the germline of another mammalian species, such as mouse, have been grafted onto human framework sequences. Additional framework region modifications can be made within the human framework sequences. Humanized forms of non-human (e.g., murine) antibodies are chimeric antibodies that contain minimal sequence derived from non-human immunoglobulin. In most cases, humanized antibodies are human immunoglobulins (recipient antibody) in which residues from a hypervariable region of the recipient are replaced by residues from a hypervariable region of a non-human species, such as mouse, rat, rabbit, or non-human primate (donor antibody) having the desired specificity, affinity, and capacity. In some cases, Fv framework (FR) residues of the human immunoglobulin are replaced by corresponding non-human residues. Furthermore, humanized antibodies may include residues that are not found in the recipient antibody or donor antibody. These modifications are made to further improve antibody performance. Generally, a 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 from a human immunoglobulin sequence. The humanized antibody will also optionally 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. The antibodies described herein may also be modified to use any Fc variant known to confer improved (e.g., reduced) effector function and / or FcR binding.Fc variants are described in, for example, International Patent Application Publication Nos. WO1988 / 07089A1, WO1996 / 14339A1, WO1998 / 05787A1, WO1998 / 23289A1, WO1999 / 51642A1, WO99 / 58572A1, WO2000 / 09560A2, WO2000 / 32767A1, WO2000 / 42072A2, WO2002 / 4 4215A2, WO2002 / 060919A2, WO2003 / 074569A2, WO2004 / 016750A2, WO2004 / 029207A2, WO2004 / 03 5752A2, WO2004 / 063351A2, WO2004 / 074455A2, WO2004 / 099249A2, WO2005 / 040217A2, WO2005 / 07 Nos. WO2005 / 0963A1, WO2005 / 077981A2, WO2005 / 092925A2, WO2005 / 123780A2, WO2006 / 019447A1, WO2006 / 047350A2, and WO2006 / 085967A2, as well as U.S. Pat. Nos. 5,648,260, 5,739,277, 5,834,250, 5,869,046, 6,096 ,871, 6,121,022, 6,194,551, 6,242,195, 6,277,375, 6,528,624, 6,538,124, 6,737,056, 6,821,505, 6,998,253, and 7,083,784 (the disclosures of which are incorporated herein by reference).
[0534] The term "chimeric antibody" is intended to refer to an antibody in which the variable region sequences are derived from one species and the constant region sequences are derived from another species, e.g., the variable region sequences are derived from a murine antibody and the constant region sequences are derived from a human antibody.
[0535] A "diabody" is a small antibody fragment that has two antigen-binding sites. The fragments bind to the same polypeptide chain (VH -V L or V L -V H ) in the light chain variable domain (V L ) connected to a heavy chain variable domain (V H ). If a linker that is too short to pair the two domains on the same chain is used, the domains are forced to pair with the complementary domains on another chain and create two antigen-binding sites. Bispecific antibodies are more fully described in, for example, 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.
[0536] The term "glycosylation" refers to modified derivatives of antibodies. An aglycosylated antibody lacks glycosylation. Glycosylation can be altered, for example, to increase the affinity of the antibody for an antigen. Such carbohydrate modifications can be achieved, for example, by altering one or more glycosylation sites within the antibody sequence. For example, one or more amino acid substitutions can be made that result in the elimination of one or more variable region framework glycosylation sites, thereby eliminating glycosylation at that site. As described in U.S. Pat. Nos. 5,714,350 and 6,350,861, aglycosylation can increase the affinity of the antibody for the antigen. Additionally or alternatively, antibodies can be made with altered types of glycosylation, for example, hypofucosylated antibodies with reduced amounts of fucosyl residues or antibodies with increased bisecting GlcNac structures. Such altered glycosylation patterns have been demonstrated to increase the potency of the antibody. Such carbohydrate modifications can be achieved, for example, by 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 to express the recombinant antibodies of the present invention, thereby producing antibodies with altered glycosylation. For example, cell lines Ms704, Ms705, and Ms709 lack the fucosyltransferase gene FUT8 (alpha(1,6) fucosyltransferase), such that antibodies expressed in Ms704, Ms705, and Ms709 cell lines lack fucose on their carbohydrates. Ms704, Ms705, and Ms709 FUT8- / - cell lines were created by targeted disruption of the FUT8 gene in CHO / DG44 cells using two replacement vectors (see, for example, 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 cell lines with a functionally disrupted FUT8 gene encoding a fucosyltransferase, such that antibodies expressed in such cell lines exhibit hypofucosylation by reducing or eliminating alpha 1,6 linkage-related enzymes, and also describes cell lines with reduced or no enzymatic activity for adding fucose to N-acetylglucosamine attached to the Fc region of antibodies, such as the rat myeloma cell line YB2 / 0 (ATCC CRL 1662). International Patent Publication No. WO 03 / 035835 describes a variant CHO cell line, Lec 13 cells, that has a reduced ability to attach fucose to Asn(297)-linked carbohydrates, which also results in hypofucosylation of antibodies expressed in the host cells (see also Shields, et al., J. Biol. Chem. 2002, 277, 26733-26740). International Patent Publication No. WO 99 / 54342 describes cell lines engineered to express glycoprotein-modifying glycosyltransferases (e.g., beta(1,4)-N-acetylglucosaminyltransferase III (GnTIII)) such that antibodies expressed in the engineered cell lines exhibit increased bisecting GlcNac structures, resulting in increased ADCC activity of the antibodies (see also Umana, et al., Nat. Biotech. 1999, 17, 176-180). Alternatively, fucose residues of antibodies can be cleaved 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.
[0537] "PEGylation" refers to a modified antibody or fragment thereof that 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 are attached to the antibody or antibody fragment. PEGylation can, for example, increase the biological (e.g., serum) half-life of an antibody. Preferably, PEGylation is carried out via an acylation or alkylation reaction with a reactive PEG molecule (or an analogous reactive water-soluble polymer). As used herein, the term "polyethylene glycol" refers to a mono(C 1 -C 10 It is intended to encompass any of the forms of PEG that have been used to derivatize other proteins, such as alkoxy- or aryloxy-polyethylene glycols, 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 present invention, for example as described in European Patent Nos. EP0154316 and EP0401384, and U.S. Patent No. 5,824,778, the disclosures of each of which are incorporated herein by reference.
[0538] The term "biosimilar" refers to a biological product that is highly similar to a reference biological product approved in the United States, despite minor differences in clinically inactive components, including monoclonal antibodies or proteins, and that has no clinically meaningful differences between the biological product and the reference product in terms of product safety, purity, and potency. In Europe, a similar bio or "biosimilar" drug is a biological product that is similar to another biological product already approved for use by the European Medicines Agency. The term "biosimilar" is also used synonymously by regulatory agencies in other countries and regions. Biological products or biopharmaceuticals are medicines made by or derived from biological sources such as bacteria 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 IL-2 protein is aldesleukin (PROLEUKIN), then the protein approved by the drug regulatory agency for aldesleukin is a "biosimilar" of aldesleukin or is a "biosimilar of" aldesleukin. In Europe, a similar biological or "biosimilar" medicinal product is a biological product similar to another biological product already authorized for use by the European Medicines Agency (EMA). The legal basis relevant for similar biological uses in Europe is Article 6 of Regulation (EC) No 726 / 2004, as amended, and Article 10(4) of Directive 2001 / 83 / EC, and therefore in Europe, a biosimilar may be authorised or approved for the subject of an authorisation or authorisation application under Article 6 of Regulation (EC) No 726 / 2004 and Article 10(4) of Directive 2001 / 83 / EC. The original biological product already authorised may be referred to as the "reference medicinal product" in Europe. Some of the requirements for a product to be considered a biosimilar are outlined in the CHMP guideline on biosimilar medicinal products. In addition, product-specific guidelines, including those relevant for monoclonal antibody biosimilars, are provided by the EMA on a product-by-product basis and are published on its website.The biosimilars described herein may be similar to the reference medicinal product in terms of quality characteristics, biological activity, mechanism of action, safety profile, and / or efficacy. Furthermore, the biosimilars may be used or intended to be used to treat the same condition as the reference medicinal product. Thus, the biosimilars described herein may be considered to have similar or very similar quality characteristics as the reference medicinal product. Alternatively, or in addition, the biosimilars described herein may be considered to have similar or very similar biological activity as the reference medicinal product. Alternatively, or in addition, the biosimilars described herein may be considered to have a similar or very similar safety profile as the reference medicinal product. Alternatively, or in addition, the biosimilars described herein may be considered to have similar or very similar efficacy as the reference medicinal product. As described herein, biosimilars in Europe are compared to a reference medicinal product authorized by the EMA. However, in some cases, the biosimilars may be compared to a biopharmaceutical product authorized outside the European Economic Area (a non-EEA authorized "comparator") in certain studies. Such studies include, for example, certain clinical studies and in vivo non-clinical studies. As used herein, the term "biosimilar" also relates to a biopharmaceutical that has been or can be compared to a non-EEA approved comparator. Particular biosimilars are proteins, such as antibodies, antibody fragments (e.g., antigen-binding portions), and fusion proteins. Protein biosimilars may have amino acid sequences with minor modifications in the amino acid structure (including, e.g., amino acid deletions, additions, and / or substitutions) that do not significantly affect the function of the polypeptide. Biosimilars may include amino acid sequences with 97% or more sequence identity, e.g., 97%, 98%, 99%, or 100%, to the amino acid sequence of its reference pharmaceutical. Biosimilars may include one or more post-translational modifications, e.g., but not limited to, glycosylation, oxidation, deamidation, and / or cleavage, that are different from the post-translational modifications of the reference pharmaceutical, provided that the difference does not result in a change in the safety and / or efficacy of the pharmaceutical. Biosimilars may have the same or different glycosylation pattern as the reference pharmaceutical.In particular, but not exclusively, a biosimilar may have a different glycosylation pattern if the difference addresses or is intended to address a safety concern associated with the reference drug. In addition, a biosimilar may deviate from the reference drug, for example, in its strength, dosage form, formulation, excipients, and / or presentation, provided that the safety and efficacy of the drug is not compromised. A biosimilar may include differences, for example, in its pharmacokinetic (PK) and / or pharmacodynamic (PD) profile compared to the reference drug, but is still considered sufficiently similar to the reference drug to be approved or considered suitable for approval. In certain circumstances, a biosimilar exhibits different binding characteristics compared to the reference drug, and the different binding characteristics are considered by regulatory authorities, such as the EMA, to not be a barrier to approval as a similar biological product. The term "biosimilar" is also used interchangeably by regulatory agencies in other countries and regions.
[0539] II. Generation of cryopreserved TIL preparations from tumor harvest Some embodiments of the invention provided herein relate to methods of generating cryopreserved TIL preparations from tumor samples taken from cancer patients before the patients receive immune checkpoint inhibitors (ICIs) and / or standard of care treatments.
[0540] In some embodiments, patients undergo ICI treatment (such as an anti-immune checkpoint antibody described herein) following tumor harvest and cryopreservation.
[0541] In some embodiments, the patient receives standard care treatment for cancer after tumor harvest and cryopreservation. Some of the treatment methods described herein include administering standard care treatment to the patient. As used herein, "standard care treatment" is a treatment process that includes a drug or combination of drugs, radiation therapy, surgery, or other medical interventions that are recognized by physicians as appropriate, accepted, and / or widely used for a particular type of patient, disease, or clinical situation. Standard care treatments for treating different types of cancer are well known by those skilled in the art. For example, the National Comprehensive Cancer Network (NCCN), an alliance of 21 major cancer centers in the United States, publishes the NCCN Clinical Practice Guidelines in Oncology (NCCN GUIDELINES®), which provides detailed, up-to-date information on standard care treatments for a wide variety of cancers (see NCCN GUIDELINES®, 2013). In some embodiments, the standard care treatment is chemotherapy, radiation therapy, surgery, targeted therapy, or any combination thereof.
[0542] In some embodiments, cryopreserved tumor harvest from a patient or subject is used to generate a TIL population after the patient has been treated with an ICI and / or standard of care therapy, and is indicative of cancer progression. In some embodiments, after cryopreservation of the tumor harvest, the patient or subject receives an ICI and / or standard of care therapy and is monitored for cancer progression. In some embodiments, cancer progression indicates the need for autologous TIL therapy.
[0543] In other embodiments, cryopreservation of tumor specimens from patients or subjects is completed prior to the progression of cancer.
[0544] In some embodiments, the methods disclosed herein provide a pharmaceutical economic advantage in the form of avoiding the costs of TIL production in cases where a patient does not develop progressive disease or is otherwise indicated for TIL therapy in the future.
[0545] 15. The method of any one of claims 1 to 14, wherein the patient exhibits progressive disease at least about 1 week, 2 weeks, 3 weeks, 1 month, 2 months, 3 months, 4 months, 5 months, 6 months, 7 months, 8 months, 9 months, 10 months, 11 months, 12 months, 13 months, 14 months, 15 months, 16 months, 17 months, 18 months, 19 months, 20 months, 21 months, 22 months, 23 months, 24 months, 25 months, 26 months, 27 months, 28 months, 29 months, 30 months, 31 months, 32 months, 33 months, 34 months, 35 months, 36 months after the cryopreservation step.
[0546] In some embodiments, the cryopreserved TIL preparations can be made from tumor samples containing TIL populations obtained and / or received from a patient or subject. The patient's tumor sample can be obtained using methods known in the art, generally via surgical resection, needle biopsy, core biopsy, mini biopsy, or other means for obtaining a sample containing a mixture of tumor cells and TIL cells. In some embodiments, multilesion sampling is used. In some embodiments, surgical resection, needle biopsy, core biopsy, mini biopsy, or other means for obtaining a sample containing a mixture of tumor cells and TIL cells includes multilesion sampling (i.e., obtaining samples from one or more tumor sites and / or locations of a patient, as well as one or more tumors at the same location or in close proximity). In general, the tumor sample can be from any solid tumor, including primary tumors, invasive tumors, or metastatic tumors. The tumor sample can be a liquid tumor, such as a tumor obtained from a hematological malignancy. The solid tumor can be of lung tissue. In some embodiments, useful TILs are obtained from non-small cell lung cancer (NSCLC). The solid tumor can be of skin tissue. In some embodiments, useful TILs are obtained from melanoma.
[0547] Once obtained, tumor samples were generally cut into pieces using sharp dissection ranging from 1 to approximately 8 mm 3 Fragmented into small pieces of about 2-3 mm 3are particularly useful. In some embodiments, TILs are cultured from these fragments using enzymatic tumor digests. Such tumor digests can be generated by incubation in enzymatic medium (e.g., Roswell Park Memorial Institute (RPMI) 1640 buffer, 2 mM glutamate, 10 mcg / mL gentamicin, 30 units / mL DNase, and 1.0 mg / mL collagenase) followed by mechanical dissociation (e.g., using a tissue dissociator). Tumor digests can be generated by placing the tumor in enzymatic medium, mechanically dissociating the tumor for approximately 1 minute, followed by incubation in 5% CO 2 The cells can be generated by incubating in a 50 mL hood at 37° C. for 30 minutes, followed by repeated cycles of mechanical dissociation and incubation under the aforementioned conditions until only small tissue fragments are present. If at the end of this process the cell suspension contains a large number of red blood cells or dead cells, density gradient separation using FICOLL branched hydrophilic polysaccharides can be performed to remove these cells. Alternative methods known in the art can be used, such as those described in U.S. Patent Application Publication No. 2012 / 0244133A1, the disclosure of which is incorporated herein by reference. Any of the aforementioned methods can be used in any of the embodiments described herein for the method of expanding TILs or the method of treating cancer.
[0548] In some embodiments, the cryopreserved TIL preparation is stored for future use. In some embodiments, cryopreservation of the tumor harvest is completed prior to progression. In some embodiments, after generation of the cryopreserved TIL preparation, the patient is monitored for the development of progressive disease on or after ICI and / or standard of care treatment. In some embodiments, the patient shows progressive cancer during or after ICI and / or standard of care treatment and is adapted for autologous TIL therapy. In some embodiments, after progression, the cryopreserved TIL preparation is thawed and expanded according to the expansion method described in the following section.
[0549] In some embodiments, the patient is a NSCLC cancer patient. In some embodiments, the patient is suffering from, suffering from, or susceptible to NSCLC. In some embodiments, the patient has metastatic NSCLC. In some embodiments, the patient has metastatic stage IV NSCLC.

[0570] A problem known in the art is cryopreserving 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 cell rupture. Muldrew and McGann, in "The osmotic rupture hypothesis of intracellular freezing injury", Biophysical Journal, 66:532-41 (1994), outline a quantitative theory of this known and widely recognized difficulty with cell, and particularly whole tissue, cryopreservation. Acker and McGann further develop the basic mechanisms of intracellular ice formation and cell damage in a later article, "Membrane damage occurs during the formation of intracellular ice," Cryo Letter, 22:241-54 (2001).
[0571] Upon thawing, damage during freezing is detected, where the tissue has substantially lost physiological structure or the cells that make up the tissue have substantially lost viability. Viability can be determined by the percentage of cells introduced into the culture medium compared to the number of cells that are allowed to grow or that exhibit markers of normal cell function. Numerous methods for identifying the percentage of viable cells are known in the art, including but not limited to dye exclusion tests such as trypan blue dye exclusion. See, for example, Strober, Curr. Protoc. Immunol., 2001, Appendix 3B, available at https: / / dx.doi.org / 10.1002 / 0471142735.ima03bs21. Viability may also be determined by metabolic activity assays, including but not limited to the MTT assay, where MTT, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, is metabolized by cellular enzymes to formazan. This enzymatic reaction converts the yellow MTT to purple formazan. See, e.g., 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).
[0572] Without being bound by theory, it is hypothesized that slow cooling produces harmless intracellular ice, see Acker and McGann, “Protective effect of intracellular ice during freezing?” Cryobiology, 46(2):197-202 (2003). The traditional approach to achieve freezing without undue cell damage or without significantly reducing cell viability has been to employ slow freezing rates. Watson et al., U.S. Pat. No. 5,891,617, emphasizes this approach, for example, step (c) of claim 1 teaches a very slow cooling rate of “about −0.3° C. / min or less.” Similarly, Comhaire et al., U.S. Pat. No. 9,938,495, teaches that “high post-thaw cell viability was obtained by slow freezing using DMSO-free cryopreservation medium” for stem cells.
[0573] Based on these exemplary teachings, the methods and products of the present disclosure are surprising and unexpected. Moreover, the present disclosure, including the examples and data therein, demonstrates a technical solution to the problem of rapidly and efficiently cryoprotecting tumor tissue, tumor fragments, or tumor specimens for use in the production of therapeutic tumor infiltrating lymphocytes.
[0574] In some embodiments, the method of cryopreserving tumor tissue for production of tumor infiltrating lymphocytes (TILs) further comprises the step (iv) of storing the frozen fragments at a temperature at least below −130° C.
