Description

[0001] Cross-references

[0002] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 336,041, filed on April 28, 2022, which is incorporated herein by reference in its entirety.

[0003] Incorporation by Reference of Electronically Submitted Materials

[0004] A sequence listing is provided with this application as a sequence listing XML "CUEB-150WO_SEQ_LIST", which was created on April 23, 2023 and is 136,686 bytes in size. The contents of the sequence listing XML are incorporated herein by reference in their entirety. Background Art

[0005] Cell therapy products contain T cells that have been modified to express proteins that bind to proteins on cancer cells. For example, "CAR-T cells" contain a chimeric antigen receptor ("CAR") that targets a tumor-associated antigen. CAR-T cells can kill tumor cells and have been successfully used to treat cancer. For example, CAR-T cells targeting CD19, BCMA, CD30, CD22, or CD20 have shown significant activity in clinical studies. However, CAR-T therapy also has disadvantages. Due to the large number of CAR-T cells administered, patients usually require a chemotherapy regimen to deplete lymphocytes before the CAR-T cells are administered. In addition, in order to maintain therapeutic levels of CAR-T cells after administration, patients may also need to be treated with aldesleukin. Treatment may result in serious adverse side effects. In addition, some patients may not achieve their desired or optimal outcomes due to suboptimal expansion or persistence of CAR-T cells in the body. Summary of the invention

[0006] The present disclosure includes disclosure of modified cytotoxic T cells (mCTL), wherein the mCTL may comprise: a) one or more nucleic acids comprising a nucleotide sequence encoding a T cell receptor (TCR) specific for an MHC class I polypeptide presenting a polypeptide comprising the amino acid sequence YMLDLQPETT (SEQ ID NO: 1) (“HPV E7 11-20 TCR") or YMLDLQPET (SEQ ID NO:2) ("HPV E7 11-19 TCR”) human papillomavirus (HPV) E7 peptide (collectively referred to as “HPV E7 11-19 / 20TCR"); and b) one or more nucleic acids comprising a nucleotide sequence encoding an antigen binding polypeptide (e.g., CAR or other polypeptides comprising an antigen binding domain specific for a cancer-associated antigen). The present disclosure also includes methods of producing mCTLs. The present disclosure also provides methods of treating cancer, comprising administering mCTLs to an individual in need thereof. The present disclosure also includes having a nucleotide sequence other than HPV E7 11-19 / 20 Disclosure of mCTLs expressing TCRs other than TCRs, and disclosure of modified cells other than T cells (e.g., NK cells) that are modified to simultaneously present TCRs and CARs or to present other cancer-associated antigen binding domains.

[0013] definition

[0014] The terms "polynucleotide" and "nucleic acid" are used interchangeably herein to refer to a polymeric form of nucleotides (ribonucleotides or deoxyribonucleotides) of any length. Thus, this term includes, but is not limited to, single-stranded, double-stranded, or multi-stranded DNA or RNA, genomic DNA, cDNA, DNA-RNA hybrids, or polymers containing purine and pyrimidine bases or other natural, chemically or biochemically modified, non-natural or derived nucleotide bases.

[0015] The terms "peptide," "polypeptide," and "protein" are used interchangeably herein and refer to a polymeric form of amino acids of any length, which may include coded and non-coded amino acids, chemically or biochemically modified or derivatized amino acids, and polypeptides with modified peptide backbones.

[0016] A polynucleotide or polypeptide has a certain "sequence identity" percentage with another polynucleotide or polypeptide, meaning that when compared, when comparing the two sequences, the percentage of the bases or amino acids is the same and is located in the same relative position. Sequence identity can be determined in many different ways. In order to determine sequence identity, various convenient methods and computer programs (e.g., BLAST, T-COFFEE, MUSCLE, MAFFT, etc.) can be used to align sequences, and the methods and computer programs can be obtained on the world wide web in the following websites: ncbi.nlm.nili.gov / BLAST, ebi.ac.uk / Tools / msa / tcoffee / , ebi.ac.uk / Tools / msa / muscle / , mafft.cbrc.jp / alignment / software / . See, for example, Altschul et al. (1990), J.Mol.Biol.215:403-10.

[0017] The term "conservative amino acid substitution" refers to the interchangeability in proteins of amino acid residues with similar side chains. For example, a group of amino acids with aliphatic side chains consists of glycine, alanine, valine, leucine, and isoleucine; a group of amino acids with aliphatic-hydroxy side chains consists of serine and threonine; a group of amino acids with amide-containing side chains consists of asparagine and glutamine; a group of amino acids with aromatic side chains consists of phenylalanine, tyrosine, and tryptophan; a group of amino acids with basic side chains consists of lysine, arginine, and histidine; a group of amino acids with acidic side chains consists of glutamate and aspartic acid; and a group of amino acids with sulfur-containing side chains consists of cysteine ​​and methionine. Exemplary conservative amino acid substitution groups are: valine-leucine-isoleucine, phenylalanine-tyrosine, lysine-arginine, alanine-valine-glycine, and asparagine-glutamine.

[0018] "T cells" include all types of immune cells that express CD3, including T helper cells (CD4 + cells), cytotoxic T cells (CD8 + cells), T regulatory cells (Treg) and NK-T cells.

[0019] The terms "expression construct" or "DNA construct" are used interchangeably herein to refer to a DNA molecule comprising a vector and at least one insert.

[0020] As used herein, the term "affinity" refers to the equilibrium constant for the reversible binding of two agents (e.g., antibody and antigen) and is expressed as the dissociation constant (K D ). Affinity can be at least 1 times, at least 2 times, at least 3 times, at least 4 times, at least 5 times, at least 6 times, at least 7 times, at least 8 times, at least 9 times, at least 10 times, at least 20 times, at least 30 times, at least 40 times, at least 50 times, at least 60 times, at least 70 times, at least 80 times, at least 90 times, at least 100 times, or at least 1,000 times or more of the affinity of the antibody to an unrelated amino acid sequence. For example, the affinity of the antibody to the target protein can be about 100 nanomolar (nM) to about 0.1 nM, about 100 nM to about 1 picomolar (pM) or about 100 nM to about 1 femtomolar (fM) or more. As used herein, the term "avidity" refers to the resistance of a complex of two or more agents to dissociation after dilution. With respect to antibodies and / or antigen-binding fragments, the terms "immunoreactivity" and "preferential binding" are used interchangeably herein. Unless otherwise stated herein, when the word "about" is used in reference to a numerical value, it means a range of ±10% of the stated numerical value, for example, "about 10" means a value of 9 to 11.

[0021] As used herein, the term "binding" (e.g., referring to the binding of a T cell regulatory polypeptide ("TMP") to a polypeptide on a T cell (e.g., a T cell receptor); or referring to the binding of an antigen binding polypeptide present in a CAR to an antigen (such as a cancer-associated antigen)) refers to a non-covalent interaction between two molecules. Non-covalent binding refers to direct association between two molecules due to, for example, electrostatic, hydrophobic, ionic and / or hydrogen bonding interactions, including interactions such as salt bridges and water bridges. Non-covalent binding interactions are typically characterized by a dissociation constant (KD) of less than 10 -6 M, less than 10 -7 M, less than 10 -8 M, less than 10 -9 M, less than 10 -10 M, less than 10 -11 M, less than 10 -12 MM, less than 10 -13 M, less than 10 -14 M or less than 10 -15 M. "Affinity" refers to the strength of non-covalent binding, with increased binding affinity correlating with lower KD. "Specific binding" generally refers to an affinity of at least about 10 -7 M or higher (e.g., 5x10 -7 M, 10 -8 M, 5x10 -8 M, 10 -9"Non-specific binding" generally refers to binding with an affinity of less than about 10 -7 M binding (e.g., affinity of 10 -6 M, 10 -5 M, 10 -4 "Specific binding" refers to the binding of a ligand to a portion of a receptor other than its designated binding site or receptor). However, in some cases, such as the binding between a TCR and a peptide / MHC complex, the range of "specific binding" can be 1 μM to 100 μM or 100 μM to 1 mM. As used herein, "covalent binding" or "covalent bond" refers to the formation of one or more covalent chemical bonds between two different molecules.

[0022] The terms "treatment", "treating", and the like are used herein to generally mean obtaining a desired pharmacological and / or physiological effect. The effect may be preventive in terms of completely or partially preventing a disease or its symptoms and / or may be therapeutic in terms of partially or completely curing a disease and / or an adverse effect attributable to a disease. As used herein, "treatment" encompasses any treatment of a disease or symptom in a mammal, and includes: (a) preventing a disease or symptom from occurring in a subject who may be susceptible to the disease or symptom but has not yet been diagnosed with the disease or symptom; (b) inhibiting the disease or symptom, i.e., preventing its development; and / or (c) alleviating the disease, i.e., causing the disease to regress. The therapeutic agent may be administered before, during, or after the onset of the disease or injury. Treatment of persistent diseases is of particular interest in cases where the treatment stabilizes or alleviates the patient's undesirable clinical symptoms. Such treatment is ideally performed before the affected tissue completely loses function. The therapy of the present invention will ideally be administered during the symptomatic stage of the disease and in some cases after the symptomatic stage of the disease.

[0023] The terms "individual", "subject", "host" and "patient" are used interchangeably herein and refer to any mammalian subject for whom diagnosis, treatment or therapy is desired. Mammals include, for example, humans, non-human primates, rodents (e.g., rats; mice), lagomorphs (e.g., rabbits), ungulates (e.g., cattle, sheep, pigs, horses, goats, etc.), and the like.

[0024] As used herein, the term "about" used in conjunction with an amount indicates that the amount may vary by 10% of the stated amount. For example, "about 100" means an amount of 90-110. When about is used in the context of a range, "about" used when referring to the lower amount of the range means that the lower amount includes an amount that is 10% lower than the lower amount of the range, and "about" used when referring to the higher amount of the range means that the higher amount includes an amount that is 10% higher than the higher amount of the range. For example, about 100 to about 1000 means that the range extends from 90 to 1100.

[0025] Unless otherwise specified, the term "substantially" is intended to encompass both "completely" and "largely but not completely". For example, an Ig Fc that "substantially does not induce ADCC" means an Ig Fc that does not induce ADCC at all or does not induce ADCC to a large extent. Unless otherwise specified, the term "substantially" as used herein means "completely or largely but not completely". As another example, a "substantially homogeneous population" means a population that is completely homogeneous or largely but not completely homogeneous.

[0026] The terms "antibody" and "immunoglobulin" include antibodies or immunoglobulins of any isotype, antibody fragments that retain specific binding to an antigen (including but not limited to: Fab, Fv, scFv and Fd fragments), chimeric antibodies, humanized antibodies, single-chain antibodies (scAb), single-domain antibodies (dAb), single-domain heavy chain antibodies, single-domain light chain antibodies, nanobodies, bispecific antibodies, multispecific antibodies, and fusion proteins comprising antigen-binding (also referred to herein as antigen-binding) portions of antibodies and non-antibody proteins. Antibodies can be detectably labeled, for example, with radioisotopes, enzymes that generate detectable products, fluorescent proteins, etc. Antibodies can be further conjugated to other moieties, such as members of specific binding pairs, for example, biotin (members of biotin-avidin specific binding pairs), etc. The term also encompasses Fab', Fv, F(ab')2 and / or other antibody fragments that retain specific binding to an antigen, as well as monoclonal antibodies. As used herein, a monoclonal antibody is an antibody produced by a group of identical cells, all of which are produced by a single cell through repeated cell replication. That is, the cell clone produces only a single antibody species. Although monoclonal antibodies can be produced using hybridoma production technology, they can also be produced using other production methods known to those skilled in the art (e.g., antibodies derived from antibody phage display libraries). Antibodies can be monovalent or divalent. Antibodies can be Ig monomers, which are "Y-shaped" molecules consisting of the following four polypeptide chains: two heavy chains and two light chains connected by disulfide bonds.

[0027] As used herein, the term "humanized immunoglobulin" refers to an immunoglobulin comprising immunoglobulin portions of different origins, wherein at least one portion comprises an amino acid sequence of human origin. For example, a humanized antibody may comprise a portion of an immunoglobulin derived from a non-human source (such as a mouse) having the desired specificity, and a portion of an immunoglobulin sequence derived from a human source (e.g., a chimeric immunoglobulin), the portion being chemically linked together by conventional techniques (e.g., synthesis) or prepared as a continuous polypeptide using genetic engineering techniques (e.g., DNA encoding a protein portion of a chimeric antibody can be expressed to produce a continuous polypeptide chain). Another example of a humanized immunoglobulin is an immunoglobulin containing one or more immunoglobulin chains, the immunoglobulin chains comprising a complementary determining region (CDR) derived from an antibody of non-human origin and a framework region of a light chain and / or a heavy chain derived from a human source (e.g., a CDR-grafted antibody with or without a framework change). Chimeric or CDR-grafted single-chain antibodies are also encompassed within the term humanized immunoglobulin. See, e.g., U.S. Pat. No. 4,816,567; European Patent No. 0,125,023 B1; U.S. Pat. No. 4,816,397; European Patent No. 0,120,694 B1; WO 86 / 01533; European Patent No. 0,194,276 B1; U.S. Pat. No. 5,225,539; European Patent No. 0,239,400 B1; and European Patent Application No. 0,519,596 A1. For single-chain antibodies, see also U.S. Pat. No. 4,946,778; U.S. Pat. No. 5,476,786; and Bird et al. (1988) Science 242:423.

[0028] As used herein, the term "nanobody" (Nb) refers to the smallest antigen-binding fragment or single variable domain (V HH ) and are known to those skilled in the art. The nanobodies are derived from heavy chain-only antibodies found in camelids (Hamers-Casterman et al. (1993) Nature 363:446; Desmyter et al. (1996) Nature Structural Biol.3:803; and Desmyter et al. (2015) Curr. Opin. Struct. Biol.32:1). Immunoglobulins lacking light polypeptide chains are found in the "Camelids" family. "Camelids" include Old World camelids (Bactrian camels and dromedaries) and New World camelids (e.g., alpacas (Llama paccos), llamas (Llama glama), guanicoes (Llama guanicoe) and llamas (Llama vicugna)). Single variable domain heavy chain antibodies are referred to herein as nanobodies or V HH Antibody.

[0029] "Antibody fragments" comprise a portion of an intact antibody, such as the antigen binding or variable region of an intact antibody. Examples of antibody fragments include Fab, Fab', F(ab')2, and Fv fragments; diabodies; linear antibodies (Zapata et al., Protein Eng. 8(10): 1057-1062 (1995)); domain antibodies (dAbs; Holt et al. (2003) Trends Biotechnol. 21: 484); single-chain antibody molecules; and multispecific antibodies formed from antibody fragments. Papainization of antibodies produces two identical antigen-binding fragments, called "Fab" fragments, each with a single antigen-binding site; and a residual "Fc" fragment, the name reflecting its ability to crystallize easily. Pepsin treatment produces a F(ab')2 fragment, which has two antigen-binding sites and is still able to cross-link antigen.

[0030] "Fv" is the smallest antibody fragment containing a complete antigen recognition and binding site. This region is composed of a dimer of a heavy chain variable domain and a light chain variable domain that are tightly and non-covalently bound. In this configuration, the three CDRs of each variable domain interact to define the antigen binding site on the surface of the VH-VL dimer. The six CDRs together confer antigen binding specificity to the antibody. However, even a single variable domain (or only half of an Fv containing three CDRs that are specific to an antigen) has the ability to recognize and bind to an antigen, although its affinity is lower than that of a complete binding site.

[0031] The "Fab" fragment also contains the constant domain of the light chain and the first constant domain (CH1) of the heavy chain. The Fab fragment differs from the Fab' fragment in that a few residues are added to the carboxyl terminus of the heavy chain CH1 domain, including one or more cysteines from the antibody hinge region. Fab' in which the cysteine ​​residues of the constant domains have free thiol groups is referred to herein as Fab'-SH. F(ab')2 antibody fragments were originally produced as pairs of Fab' fragments with hinge cysteines between the Fab' fragments. Other chemical couplings of antibody fragments are also known.

[0032] The "light chains" of antibodies (immunoglobulins) from any vertebrate species can be assigned to one of two clearly distinct types, called kappa and lambda, based on the amino acid sequences of their constant domains. Immunoglobulins can be assigned to different classes depending on the amino acid sequence of their heavy chain constant domains. There are five major classes of immunoglobulins: IgA, IgD, IgE, IgG, and IgM, and several of these classes can be further divided into subclasses (isotypes), such as IgG1, IgG2, IgG3, IgG4, IgA, and IgA2. Subclasses can be further divided into different types, such as IgG2a and IgG2b.

[0033] "Single-chain Fv" or "sFv" or "scFv" antibody fragments comprise the V H Domain and V L In some embodiments, the Fv polypeptide further comprises a polypeptide linker between the VH domain and the VL domain, which enables the sFv to form a desired structure for antigen binding. For a review of sFv, see Pluckthun in The Pharmacology of Monoclonal Antibodies, Vol. 113, Rosenburg and Moore, ed., Springer-Verlag, New York, pp. 269-315 (1994).

[0034] The term "diabodies" refers to small antibody fragments with two antigen-binding sites, which fragments are comprised of the same polypeptide chain (V H -V L ) is a heavy chain variable domain (VH) connected to a light chain variable domain (VL) in a single chain. 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 more fully described in, for example, EP 404,097; WO 93 / 11161; and Hollinger et al. (1993) Proc. Natl. Acad. Sci. USA 90:6444-6448.

[0035] As used herein, the term "CDR" or "complementarity determining region" is intended to mean the non-contiguous antigen binding sites found within the variable regions of heavy and light chain polypeptides. CDRs have been described in Kabat et al. (1977) J. Biol. Chem. 252: 6609; Kabat et al., US Pept. of Health and Human Services, "Sequences of proteins of immunological interest" (1991) (also referred to herein as Kabat 1991); Chothia et al. (1987) J. Mol. Biol. 196: 901 (also referred to herein as Chothia 1987); and MacCallum et al. (1996) J. Mol. Biol. 262: 732, where the definitions include overlaps or subsets of amino acid residues when compared to each other. Nevertheless, the application of any definition to refer to the CDR of an antibody or a grafted antibody or variant thereof is intended to fall within the scope of the term as defined and used herein. Table 1 below lists the amino acid residues encompassing the CDRs as defined by the various references cited above for comparison.

[0041] As used herein, the terms "CDR-L1", "CDR-L2" and "CDR-L3" refer to the first CDR, the second CDR and the third CDR in the light chain variable region, respectively. As used herein, the terms "CDR-H1", "CDR-H2" and "CDR-H3" refer to the first CDR, the second CDR and the third CDR in the heavy chain variable region, respectively. As used herein, the terms "CDR-1", "CDR-2" and "CDR-3" refer to the first CDR, the second CDR and the third CDR in the variable region of either chain, respectively.

[0042] As used herein, when the term "framework" is used to refer to an antibody variable region, it is intended to refer to all amino acid residues outside the CDR region within the antibody variable region. The variable region framework is typically a discontinuous amino acid sequence between about 100-120 amino acids in length, but only those amino acids outside the CDR are intended to be referenced. As used herein, the term "framework region" is intended to refer to each domain of the framework separated by the CDRs.

[0053] The present disclosure provides a method for producing a HPV E7 11-19 / 20 The present disclosure provides a method for treating cancer, comprising administering to an individual in need thereof a mCTL comprising HPV E7 11-19 / 20 The present disclosure also provides mCTLs comprising HPVE7 11-19 / 20 mCTLs that contain a TCR and an antigen-binding polypeptide (e.g., a CAR or other polypeptide comprising an antigen-binding domain specific for a cancer-associated antigen).

[0054] Therefore, the present disclosure provides mCTL, wherein the mCTL comprises: a) comprising a polypeptide encoding PV E7 11-19 / 20 The invention relates to a method for treating a cancer-associated antigen in a humanized, non-human 247 cell line comprising a nucleic acid comprising a nucleotide sequence encoding a TCR; and b) one or more nucleic acids comprising a nucleotide sequence encoding a CAR, wherein the CAR comprises an antigen binding domain specific for a cancer associated antigen.

[0056] Although mCTLs are shown herein to have HPV E7 11-19 / 20TCR, i.e., a T cell receptor (TCR) with specificity for MHC class I polypeptides presenting human papillomavirus (HPV) E7 peptides comprising the amino acid sequence YMLDLQPETT (SEQ ID NO: 1) or YMLDLQPET (SEQ ID NO: 2), but it should be understood that mCTLs may have alternative TCRs specific for different peptides, in which case TMPs presenting peptides specific for alternative TCRs will be used. Similarly, mCTLs are shown to include CARs, but mCTLs may be other cell therapy products that include antigen binding domains for cancer-associated antigens, where the antigen binding domains are not CARs. The present disclosure explicitly contemplates mCTLs that include TCRs specific for different peptides and / or antigen binding domains other than CARs. Similarly, although the present disclosure is primarily directed to modified cytotoxic T cells (mCTLs), such as CAR-T cells, it should be understood that the disclosure herein can be used to modify other types of cytotoxic cells, such as NK cells, macrophages; ILCs (innate lymphocytes), which have natural or modified antigen binding domains. T cells can include classical T cells (expressing αβ receptors) or T cells expressing γ / δ TCRs; CD8 phenotype and CD4 phenotype; MAIT T cells restricted to MR-1 nonclassical HLA, killer T cells, and killer innate-like T cells.

Such cells are referred to as "unmodified T cells". Therefore, the in vitro composition of the present disclosure may be a heterogeneous population comprising mCTL and unmodified T cells. In some cases, 1% to 20% of the total number of T cells in the composition are mCTL. In some cases, 1% to 5%, 5% to 10%, 10% to 15% or 15% to 20% of the total number of T cells in the composition are mCTL. In some cases, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 50%, at least 60%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 98%, at least 99% or more of the total number of T cells in the composition are mCTL. In some cases, 20% to 30%, 30% to 40%, 40% to 50%, 50% to 60%, 60% to 70%, 70% to 80%, 80% to 90%, or 90% to 100% of the total number of T cells in the composition are mCTLs. Thus, in some cases, the T cell population in the composition is a substantially homogeneous population of mCTLs. As described above, "substantially homogeneous population" means a population that is completely homogeneous or largely but not completely homogeneous.

[0058] An exemplary use of an in vivo composition comprising mCTL is schematically shown in Figure 1 In vitro cell populations were modified to express CARs specific for target cancer-associated antigens and to express heterologous HPV E7 11-19 / 20 TCR. The in vitro composition comprising the target modified T cell is then administered to an individual in need thereof, e.g., an individual with a cancer that expresses the target cancer associated antigen. A T cell modulating polypeptide (TMP) comprising an HPV E7 peptide comprising the amino acid sequence YMLDLQPETT (SEQ ID NO: 1) or YMLDLQPET (SEQ ID NO: 2) can also be administered to the individual. The TMP comprises an immunomodulatory polypeptide that provides an HPV E7 peptide that binds to the HPV E7 peptide present in the TMP. 11-19 / 20 Activation of T cells with TCR. Modified target T cells (e.g., mCTL) will target cancer cells expressing cancer-associated antigens presented by CAR. TMP will activate the modified target T cells by binding to the TCR present on the modified target T cells. The activation of the modified target can provide one or both of the following: (i) increase direct killing of cancer cells; and (ii) increase the secretion of cytokines that promote the anti-cancer activity of resident immune cells. TMP can increase the in vivo proliferation of mCTL, thereby reducing the number of mCTLs required for anti-cancer therapy, and also reduce or substantially eliminate the need for lymphocyte clearance chemotherapy before administering mCTL, and / or reduce or substantially eliminate the use of recombinantly produced IL-2 (e.g., aldesleukin) after administering CAR-T cells. )The need for treatment.

[0138] Hinge area

[0139] As described above, CAR may include a hinge region between the extracellular domain and the transmembrane domain. As used herein, the term "hinge region" refers to a flexible polypeptide connection region (also referred to herein as a "hinge" or "spacer"), which provides structural flexibility and spacing for the flanking polypeptide region, and may be composed of natural or synthetic polypeptides. The hinge region may include a complete hinge region derived from an antibody of a different class or subclass from the CH1 domain. The term "hinge region" may also include regions derived from CD8 and other receptors, which provide similar functions in providing flexibility and spacing for the flanking regions.

[0140] The hinge region may be about 4 amino acids to about 50 amino acids in length, e.g., about 4 aa to about 10 aa, about 10 aa to about 15 aa, about 15 aa to about 20 aa, about 20 aa to about 25 aa, about 25 aa to about 30 aa, about 30 aa to about 40 aa, or about 40 aa to about 50 aa.

[0147] Intracellular domain – signaling polypeptide

[0148] The intracellular portion of CAR may include a signaling polypeptide. Suitable signaling polypeptides include, for example, intracellular signaling polypeptides containing an immunoreceptor tyrosine-based activation motif (ITAM). The ITAM motif is YX1X2L / I, where X1 and X2 are independently any amino acids. In some cases, the intracellular signaling domain of the subject CAR comprises 1, 2, 3, 4 or 5 ITAM motifs. In some cases, the ITAM motif is repeated twice in the intracellular signaling domain, wherein the first and second instances of the ITAM motif are separated by 6 to 8 amino acids from each other, for example (YX1X2L / I)(X3) n (YX1X2L / I), wherein n is an integer from 6 to 8, and each of the 6-8 X3 can be any amino acid. In some cases, the intracellular signaling domain of CAR comprises 3 ITAM motifs.

[0149] A suitable intracellular signaling domain may be a portion containing an ITAM motif that is derived from a polypeptide containing an ITAM motif. For example, a suitable intracellular signaling domain may be a domain containing an ITAM motif from any protein containing an ITAM motif. Therefore, a suitable intracellular signaling domain need not contain the complete sequence of the complete protein from which it is derived. Examples of suitable polypeptides containing an ITAM motif include, but are not limited to: DAP12; FCER1G (Fcε receptor Iγ chain); CD3D (CD3δ); CD3E (CD3ε); CD3G (CD3γ); CD3Z (CD3ζ); and CD79A (antigen receptor complex-associated protein α chain).

[0158] The pharmaceutical composition may comprise an amount of mCTL of the present disclosure and a pharmaceutically acceptable excipient. In some cases, the subject pharmaceutical composition will be suitable for administration to a subject, e.g., will be sterile. For example, in some cases, the subject pharmaceutical composition will be suitable for administration to a human subject, e.g., when the composition is sterile and does not contain detectable pyrogens and / or other toxins, or when the presence of such detectable pyrogens and / or other toxins is within acceptable limits set by applicable regulatory agencies (e.g., the U.S. Food and Drug Administration (USF&DA)).

[0159] The present disclosure provides a container comprising the mCTL of the present disclosure, such as a liquid composition. The container can be, for example, a syringe, an ampoule, etc. In some cases, the container is sterile. In some cases, both the container and the composition are sterile.

[0160] In some cases, the mCTL is present in a liquid composition. Thus, the present disclosure provides compositions (e.g., liquid compositions, including pharmaceutical compositions) comprising mCTL. In some cases, the compositions of the present disclosure comprise: a) mCTL; and b) saline (e.g., 0.9% NaCl). In some cases, the composition is sterile.

The present disclosure provides a mixture of mCTL of the present disclosure and TMP, wherein the TMP comprises an HPV16 peptide comprising an amino acid sequence of YMLDLQPET (SEQ ID NO: 2).

[0162] T cell regulatory polypeptide (TMP)

[0163] T cell modulatory polypeptides (TMPs) suitable for use herein include single-chain polypeptides or heterodimeric polypeptides comprising: (i) a peptide, such as an HPV16 peptide comprising the amino acid sequence YMLDLQPETT (SEQ ID NO: 1) or YMLDLQPET (SEQ ID NO: 2); (ii) a β2 microglobulin (β2M) polypeptide; (iii) an immunomodulatory polypeptide (or "MOD"), such as an IL-2 polypeptide; (iv) a major histocompatibility complex class I (MHC class I) heavy chain polypeptide; and (v) a scaffold polypeptide, such as an immunoglobulin (Ig) Fc polypeptide.

[0164] For example, the TMP may comprise a heterodimeric polypeptide comprising: a) a) a first polypeptide comprising: (i) an HPV16 peptide comprising the amino acid sequence YMLDLQPETT (SEQ ID NO: 1); (ii) a linker; and (iii) a β2 microglobulin (β2M) polypeptide; and b) a second polypeptide comprising: (i) two copies of an IL-2 polypeptide; (ii) a major histocompatibility complex class I (MHC class I) heavy chain polypeptide; and (iii) an immunoglobulin (Ig) Fc polypeptide, e.g., a variant IgG1 Fc polypeptide having a significantly reduced ability to achieve complement dependent cytotoxicity (CDC) or antibody dependent cellular cytotoxicity (ADCC).

[0165] The β2M polypeptide may comprise an amino acid sequence having at least 90%, at least 95%, at least 98%, at least 99%, or 100% amino acid sequence identity to the following β2M amino acid sequence:

[0166] In some cases, the β2M polypeptide comprises an amino acid sequence having at least 90%, at least 95%, at least 98%, at least 99%, or 100% amino acid sequence identity to the following β2M amino acid sequence: IQRTPKIQVY

[0167]

[0168] wherein amino acid 12 is Cys. In some cases, the β2M polypeptide comprises the amino acid sequence

[0169] In some cases, the IL-2 polypeptide is a variant of a naturally occurring co-stimulatory protein, and the variant exhibits reduced affinity to its corresponding (homologous) co-stimulatory protein (e.g., IL-2R) on T cells compared to the affinity of the naturally occurring IL-2 polypeptide to the corresponding co-stimulatory protein (IL-2R). In some cases, the IL-2 variant exhibits reduced binding to IL-2Rα, thereby minimizing or substantially reducing the activation of IL-2 variants to Treg. Or or in addition, in some cases, IL-2 variant MOD exhibits reduced binding to IL-2Rβ, so that IL-2 variant MOD exhibits overall reduced affinity to IL-2R. In some cases, IL-2 variant MOD exhibits two characteristics, that is, it exhibits reduced or substantially no binding to IL-2Rα, and also exhibits reduced binding to IL-2Rβ, so that IL-2 variant polypeptides exhibit overall reduced affinity to IL-2R. For example, IL-2 variants with substitutions at H16 and F42 show reduced binding to IL-2Rα and IL-2Rβ. See, Quayle et al., Clin Cancer Res; 26(8) April 15, 2020, which discloses that IL-2 polypeptides with H16A and F42A substitutions have 110-fold and 3-fold reduced binding affinity for human IL-2Rα and IL-2Rβ, respectively, compared to wild-type IL2 binding, primarily due to faster dissociation rates for each of these interactions. TMPs comprising such variants (including variants exhibiting reduced binding to IL-2Rα and IL-2Rβ) show the ability to preferentially bind to and activate IL-2 receptors on T cells containing target TCRs specific for peptide epitopes on TMPs, and are therefore less likely to deliver IL-2 to non-target T cells, i.e., T cells that do not contain TCRs that specifically bind to peptide epitopes on TMPs. In other words, the binding of IL-2 variant MOD to its co-stimulatory polypeptide on T cells is substantially driven by the binding of the MHC-epitope portion rather than by the binding of IL-2. In some cases, the IL-2 variant MOD of the present disclosure exhibits reduced binding to IL-2Rγ. Reduced binding to IL-2Rγ may be associated with reduced binding to IL-2Rα and / or IL-2Rβ.

[0170] In some cases, a suitable variant IL-2 polypeptide comprises an amino acid sequence having at least 90%, at least 95%, at least 98%, at least 99%, or 100% amino acid sequence identity to the following amino acid sequence:

[0171] That is, the variant IL-2 polypeptide has the amino acid sequence of wild-type IL-2 but has H16A and F42A substitutions (shown in bold). Alternatively, the aforementioned sequence can be used, but with substitutions other than Ala at H16 and / or F42, for example, H16T can be used instead of H16A. In some cases, the variant IL-2 polypeptide present in TMP comprises the following amino acid sequence:

[0172] In some cases, the variant IL-2 polypeptide present in TMP comprises the following amino acid sequence:

[0173] In some cases, the TMP comprises two copies of such a variant IL-2 polypeptide connected by a linker.

[0175]

[0176] In some instances, the MHC class I heavy chain polypeptide comprises Ala at position 84 and Cys at position 236. Thus, for example, in some instances, the MHC class I heavy chain polypeptide comprises an amino acid sequence having at least 80%, at least 85%, at least 90%, at least 95%, at least 98%, at least 99%, or 100% amino acid sequence identity to the following HLA-A heavy chain amino acid sequence:

[0177]

[0178] wherein amino acid 84 is Ala and amino acid 236 is Cys.

[0179] As described above, the TMP comprises an Ig Fc polypeptide. The Ig Fc polypeptide is also referred to herein as an "Fc polypeptide". The Ig Fc polypeptide of the TMP may be a variant of human IgG1 Fc, human IgG2 Fc, human IgG3 Fc, human IgG4 Fc, etc., or a wild-type Ig Fc polypeptide. Variants include naturally occurring variants, non-naturally occurring variants, and combinations thereof. For example, Ig Fc may be a variant of an Fc polypeptide (such as a human IgG1 Fc polypeptide) that has a reduced or substantially eliminated ability to achieve complement dependent cytotoxicity (CDC) or antibody dependent cellular cytotoxicity (ADCC).

[0180] In some cases, the Fc polypeptide present in the TMP is an IgG1 Fc polypeptide or a variant of an IgG1 Fc polypeptide. For example, in some cases, the Fc polypeptide present in the TMP comprises an amino acid sequence having at least 80%, at least 85%, at least 90%, at least 95%, at least 98%, at least 99%, or 100% amino acid sequence identity to the following human IgG1 Fc polypeptide amino acid sequence: NO:9). Such IgG1 Fc polypeptides may or may not contain a C-terminal lysine.

[0181] In some cases, the Fc polypeptide present in the TMP comprises an amino acid sequence having at least 80%, at least 85%, at least 90%, at least 95%, at least 98%, at least 99%, or 100% amino acid sequence identity to the following human IgG1 Fc polypeptide amino acid sequence:

[0182] In some cases, the Ig Fc polypeptide present in the TMP comprises Figure 3D , wherein amino acid 14 is Ala and amino acid 15 is Ala. Thus, in some cases, the Ig Fc polypeptide present in the TMP comprises an amino acid sequence having at least 80%, at least 85%, at least 90%, at least 95%, at least 98%, at least 99%, or 100% amino acid sequence identity to the Ig Fc polypeptide amino acid sequence shown in:

[0191] In some cases, TMP dimerizes. For example, in some cases, two Ig Fc polypeptides (e.g., two IgG1 Fc polypeptides) are spontaneously linked by one or more interchain disulfide bonds to form a homodimer. Thus, in some cases, TMP is a protein comprising two heterodimers, as described above.

[0219] a) a first polypeptide comprising the amino acid sequence shown in SEQ ID NO: 14;

[0220] b) a second polypeptide comprising the amino acid sequence shown in SEQ ID NO: 15 (which includes an Ig Fc polypeptide not including a C-terminal Lys) or SEQ ID NO: 18 (which includes an Ig Fc polypeptide including a C-terminal Lys);

[0221] wherein the first polypeptide and the second polypeptide of each heterodimer are covalently linked to each other via a disulfide bond between the Cys residue at amino acid 12 of the β2M polypeptide and the Cys residue at amino acid 236 of the class I MHC heavy chain polypeptide, and

[0222] The two heterodimers are linked to each other via one or more disulfide bonds, which connect the IgG1 Fc polypeptide of one heterodimer to the variant immunoglobulin Fc polypeptide of the other heterodimer.

[0223] In some cases, the TMP is a single-chain polypeptide or a homodimer of two single-chain polypeptides comprising the same amino acid sequence. For example, the TMP can be a single-chain polypeptide comprising (i) an HPV16 E7 epitope comprising the amino acid sequence YMLDLQPETT (SEQ ID NO: 1) or YMLDLQPET (SEQ ID NO: 2), (ii) a β2 microglobulin (β2M) polypeptide, (iii) one or more copies of an IL-2 polypeptide comprising the amino acid sequence shown in SEQ ID NO: 5, (iv) a class I MHC heavy chain polypeptide, (v) a variant human IgG1 Fc polypeptide, and (vi) one or more independently selected linkers for connecting the single-chain polypeptide components. The single-chain polypeptide may further comprise one or more disulfide bonds.

[0224] For example, TMP is a homodimer comprising two single-chain polypeptides, wherein each single-chain polypeptide comprises (i) an HPV16 E7 epitope comprising the amino acid sequence YMLDLQPETT (SEQ ID NO: 1) or YMLDLQPET (SEQ ID NO: 2), (ii) a β2 microglobulin (β2M) polypeptide comprising the amino acid sequence set forth in SEQ ID NO: 4, (iii) two copies of an IL-2 polypeptide, each copy comprising the amino acid sequence set forth in SEQ ID NO: 5, (iv) an MHC class I heavy chain polypeptide comprising the amino acid sequence set forth in SEQ ID NO: 8; and (v) a variant IgG1 Fc polypeptide comprising amino acids having 98% identity to the amino acid sequence set forth in SEQ ID NO: 9 or SEQ ID NO: 10.

[0225] wherein the two single-chain polypeptides are linked to each other via one or more disulfide bonds, wherein the disulfide bonds link the variant IgG1 Fc polypeptide of one single-chain polypeptide to the variant IgG1 Fc polypeptide of the other single-chain polypeptide, and

[0226] One or more independently selected linkers may connect the components of each single polypeptide chain.

[0227] Method for preparing MCTL

[0228] The present disclosure provides a method for preparing mCTL. The method comprises introducing one or more nucleic acids into T cells, wherein the one or more nucleic acids comprise a polypeptide encoding (i) an antigen binding domain specific for a cancer-associated antigen (e.g., CAR) and (ii) HPV E7 11-19 / 11-20 Nucleotide sequences of TCRs. Methods for introducing such nucleic acids into T cells are known.

[0229] The present disclosure provides a composition comprising: a) a first nucleic acid (which may be present in a recombinant expression vector) comprising a nucleotide sequence encoding a polypeptide comprising an antigen binding domain specific to a cancer associated antigen (e.g., CAR); and b) a second nucleic acid (which may be present in a recombinant expression vector) comprising a nucleotide sequence encoding an HPV E7 11-19 / 20 The present disclosure provides a composition comprising: a) a first recombinant expression vector comprising a nucleotide sequence encoding a polypeptide (e.g., CAR) comprising an antigen binding domain specific to a cancer-associated antigen; and b) a second recombinant expression vector comprising a nucleotide sequence encoding an HPV E7 11-19 / 20 In some cases, the second nucleic acid or the second recombinant expression vector comprises a nucleotide sequence encoding a TCR. Figure 2A The α chain and Figure 2B In some cases, the second nucleic acid or the second recombinant expression vector comprises a nucleotide sequence encoding Figure 2C The α chain and Figure 2D The nucleotide sequence of the β chain amino acid sequence shown in .

[0230] The nucleic acid comprising the nucleotide sequence encoding CAR or TCR may be present in an expression vector, such as a recombinant expression vector. Recombinant expression vectors and methods for preparing recombinant expression vectors are known. In some cases, for example, the recombinant expression vector is a viral construct, such as a recombinant adeno-associated virus (AAV) construct, a recombinant adenovirus construct, a recombinant lentiviral construct, a recombinant retroviral construct, etc. In some cases, the nucleic acid comprising the nucleotide sequence encoding CAR or TCR is present in a recombinant lentiviral vector. In some cases, the nucleic acid comprising the nucleotide sequence encoding CAR or TCR is present in a recombinant AAV vector.

[0231] The nucleotide sequence encoding the CAR and / or the nucleotide sequence encoding the TCR can be operably connected to one or more transcription control elements, such as a promoter, such as a promoter functional in a eukaryotic cell, wherein the promoter can be a constitutive promoter or an inducible promoter. Suitable promoters are known in the art and any such promoter can be used.

[0232] In some cases, the promoter is a CD8 cell-specific promoter, a CD4 cell-specific promoter, a neutrophil-specific promoter, or a natural killer (NK) cell-specific promoter. For example, the CD4 gene promoter can be used; see, for example, Salmon et al. (1993) Proc. Natl. Acad. Sci. USA 90: 7739; and Marodon et al. (2003) Blood 101: 3416. As another example, the CD8 gene promoter can be used.

[0233] Any method for introducing nucleic acid into cells can be used to introduce nucleic acid (e.g., recombinant expression vector) encoding CAR or encoding TCR into target T cells. Suitable methods include viral transfection (e.g., where nucleic acid is a lentiviral vector or other viral vectors comprising a nucleotide sequence encoding CAR or TCR), electroporation, diethylaminoethyl (DEAE)-dextran-mediated transfection, lipofection, etc.

[0234] In some cases, once one or more nucleic acids (e.g., recombinant expression vectors) are introduced into T cells in vitro, a mixed cell population comprising mCTL and unmodified T cells is generated. In some cases, mCTL are separated from unmodified T cells. In some cases, mCTL comprises at least 80%, at least 85%, at least 90%, at least 95%, at least 98% or at least 99% of the total T cell population.

[0235] Methods for separating mCTL from unmodified T cells are known in the art, and any known method can be used. For example, in some cases, a mixed cell population comprising mCTL and unmodified T cells is contacted with an immobilized HPV E7 peptide comprising the amino acid sequence YMLDLQPETT (SEQ ID NO: 1) or YMLDLQPET (SEQ ID NO: 2), allowing mCTL to bind to the immobilized HPV E7 peptide, thereby immobilizing the mCTL, and separating the immobilized mCTL from the unbound cells. In some cases, the immobilized HPV E7 peptide is immobilized on a solid support, such as beads. In some cases, the immobilized HPV E7 peptide is bound to an immobilized MHC class I polypeptide.

[0236] In some cases, the method includes contacting in vitro mCTL with a TMP as described herein. Such a contact step can increase the proliferation and / or activation of mCTL. In some cases, contacting mCTL with TMP increases the proliferation of mCTL by at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 75%, at least 100% (or 2 times), at least 2.5 times, at least 5 times, at least 10 times, at least 50 times, at least 100 times or more than 100 times compared to the proliferation level in the absence of TMP (i.e., the proliferation level of mCTL not contacted with TMP). In some cases, the number of mCTLs increases after contact with TMP by at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 75%, at least 100% (or 2-fold), at least 2.5-fold, at least 5-fold, at least 10-fold, at least 50-fold, at least 100-fold, or more than 100-fold compared to the number of mCTLs that have not been contacted with TMP.

[0237] Treatment

[0238] The present disclosure provides methods for treating cancer in an individual. The methods generally involve administering to an individual with cancer a composition comprising mCTL of the present disclosure. In some cases, the method comprises: a) introducing to an individual with cancer a composition comprising mCTL and a composition comprising TMP as described herein. In some cases, the method comprises: a) introducing to an individual with cancer a composition comprising mCTL; and b) administering to the individual a TMP as described herein.

[0239] The method of the present disclosure includes administering an effective amount of mCTL. An "effective amount" of mCTL is an amount that, when administered to an individual in need as a monotherapy or as part of a combination therapy (e.g., as part of a combination therapy using TMPs and / or immune checkpoint inhibitors, as discussed below) at one or more doses, reduces the overall tumor load of the individual, i.e., the amount of cancer in the body, or keeps the patient's total tumor load relatively stable for a sufficient period of time so that the patient has "stable disease" as confirmed by standard RECIST criteria.

[0240] In some cases, an "effective amount" of mCTLs is an amount that, when administered to an individual in need thereof at one or more doses as a monotherapy or as part of a combination therapy (e.g., as part of a combination therapy with TMPs and / or an immune checkpoint inhibitor), results in a sufficient reduction in tumor size, and for a sufficient period of time, for the patient to have a confirmed "partial response" as determined by standard RECIST criteria.

[0241] In some cases, an "effective amount" of mCTLs is an amount that, when administered to an individual in need thereof at one or more doses as a monotherapy or as part of a combination therapy (e.g., as part of a combination therapy with TMPs and / or an immune checkpoint inhibitor), results in a sufficient reduction in tumor size, and for a sufficient period of time, for the patient to have a confirmed "complete response" as determined by standard RECIST criteria.

[0242] In some cases, an "effective amount" of mCTL is an amount that, when administered as a monotherapy or as part of a combination therapy (e.g., as part of a combination therapy using TMP and / or an immune checkpoint inhibitor) to an individual in need (an individual with a tumor) at one or more doses, reduces the tumor volume of the individual. For example, in some cases, an "effective amount" of mCTL is an amount that, when administered as a monotherapy or as part of a combination therapy (e.g., as part of a combination therapy using TMP and / or an immune checkpoint inhibitor) to an individual in need (an individual with a tumor) at one or more doses, reduces the tumor volume of the individual by at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, or at least 95% compared to the tumor volume of the individual before the administration of mCTL or without the administration of TMP. The tumor volume is determined using the formula (length x width x width) / 2, where the length represents the maximum tumor diameter and the width represents the perpendicular tumor diameter.

[0243] In some cases, an "effective amount" of mCTL is an amount that, when administered to an individual in need at one or more doses, increases the overall survival of the individual. For example, in some cases, an "effective amount" of mCTL is an amount that, when administered to an individual in need at one or more doses as a monotherapy or as part of a combination therapy (e.g., as part of a combination therapy using TMP and / or an immune checkpoint inhibitor), increases the survival of the individual by at least 1 month, at least 2 months, at least 3 months, 3 months to 6 months, 6 months to 1 year, 1 year to 2 years, 2 years to 5 years, 5 years to 10 years, or more than 10 years, compared to the expected survival time of the individual without the administration of TMP.

[0244] In some cases, an "effective amount" of mCTL is an amount that, when administered to an individual in need thereof at one or more doses as a monotherapy or as part of a combination therapy (e.g., as part of a combination therapy using TMPs and / or immune checkpoint inhibitors), reduces the level of circulating tumor DNA ("ctDNA") in the patient by at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, or at least 95% compared to the level of ctDNA in the individual before administration of mCTL or without administration of TMPs. Any known method can be used to determine ctDNA levels; see, e.g., Cescon et al. (2020) Nature Cancer 1:276.

[0245] In some cases, the methods of the present disclosure include: a) contacting mCTL with TMP in vitro; and b) administering an effective amount of a composition comprising a mixture of mCTL and TMP to an individual in need thereof. In some cases, the contacting step is performed for a period of time to allow proliferation of mCTL in vitro. For example, in some cases, the contacting step is performed for a period of time of 1 hour to 36 hours (e.g., 1 hour to 2 hours, 2 hours to 4 hours, 4 hours to 8 hours, 8 hours to 12 hours, 12 hours to 18 hours, 18 hours to 24 hours, or 24 hours to 36 hours or longer than 36 hours prior to the administering step).

[0246] In some cases, the methods of the present disclosure include: a) administering an effective amount of mCTL to an individual in need thereof; and b) administering an effective amount of TMP to the individual. In some cases, TMP is administered prior to administering mCTL. In some cases, TMP is administered both prior to and after administering mCTL. In some cases, TMP is administered both prior to and after administering mCTL.

[0247] In some cases, TMP is administered after mCTL is administered, for example, about 1 hour to about 1 week after the mCTL administration step. For example, in some cases, step (b) is performed within a time period of 1 hour to about 2 hours, 2 hours to 4 hours, 4 hours to 8 hours, 8 hours to 12 hours, 12 hours to 18 hours, 18 hours to 24 hours, 24 hours to 2 days, 2 days to 4 days, or 4 days to 1 week after step (a). Thereafter, TMP may be re-administered regularly according to the patient's doctor's determination to maintain the patient's desired mCTL level. For example, TMP may be administered weekly, every two weeks, every three weeks, monthly, or less than monthly frequency. After the initial administration of mCTL, the frequency of administration of TMP may also be higher, and then the frequency of administration may be reduced after the desired mCTL cell level is reached.

[0248] In some cases, the methods of the present disclosure include 10 cells / kg body weight to 10 9 For example, in some cases, the methods of the present disclosure include administering mCTLs in an amount of 10 cells / kg body weight to 10 2 cells / kg body weight, 10 2 cells / kg body weight to 10 3 cells / kg body weight, 10 3 cells / kg body weight to 10 4 cells / kg body weight, 10 4 cells / kg body weight to 10 5 cells / kg body weight, 10 5 cells / kg body weight to 10 6 cells / kg body weight, 10 6 cells / kg body weight to 10 7 cells / kg body weight, 10 7 cells / kg body weight to 10 8 cells / kg body weight, 10 8 cells / kg body weight to 10 9 In some cases, the amount of mCTL is equal to or less than a number selected from the group consisting of: 10 cells / kg body weight, 10 2 cells / kg body weight, 10 3 cells / kg body weight, 10 4 cells / kg body weight, 10 5 cells / kg body weight, 10 6 cells / kg body weight, 10 7 cells / kg body weight, 10 8 cells / kg body weight and 10 9cells / kg body weight. In some cases, the method comprises administering a 7 In some cases, the method comprises administering a composition comprising equal to or less than 10 mCTLs. 6 In some cases, the method comprises administering a composition comprising equal to or less than 10 mCTLs. 5 The composition of mCTLs is in the amount of cells / kg body weight.

[0249] When the methods of the present disclosure include administering TMP, TMP can be administered in an amount between 0.1 mg / kg body weight and 20 mg / kg body weight, such as between 0.1 mg / kg body weight and 10 mg / kg body weight, such as between 0.5 mg / kg body weight and 5 mg / kg body weight, between 1 mg / kg body weight and 5 mg / kg body weight; between 5 mg / kg body weight and 10 mg / kg; between 10 mg / kg body weight and 15 mg / kg; between 15 mg / kg body weight and 20 mg / kg body weight, however, dosages exceeding this exemplary range are also contemplated, particularly in light of the above factors. For example, TMP can be administered in an amount of about 1 mg / kg body weight to about 5 mg / kg body weight, about 5 mg / kg body weight to about 10 mg / kg body weight, about 10 mg / kg body weight to about 15 mg / kg body weight, about 15 mg / kg body weight to about 20 mg / kg body weight. If the regimen is a continuous infusion, the range can also be 1 μg to 10 mg per kilogram of body weight per minute.

[0250] When a TMP as described above is employed, for example a homodimer comprising two heterodimers, wherein each heterodimer comprises two copies of an IL-2 polypeptide, each copy comprising the amino acid sequence set forth in SEQ ID NO:5, such homodimers can be administered in an amount of 4 mg / kg body weight or less, such as 3 mg / kg body weight, 2 mg / kg body weight, 1 mg / kg body weight or less than 1 mg / kg body weight, the specific amount being determined by the patient's physician to maintain the patient's desired mCTL level.

[0251] Generally speaking, when a combination therapy of mCTL and TMP is used, the amount of mCTL administered can be at least one order of magnitude lower than the dose in the absence of TMP, i.e., because TMP can increase the amount of mCTL in the patient. In some cases, the amount of mCTL administered can be at least two orders of magnitude lower than the dose in the absence of TMP. In some cases, the amount of mCTL administered can be at least three orders of magnitude lower than the dose in the absence of TMP.

[0252] For example, according to the FDA-approved package insert, CAR-T cells are genetically modified to produce The amount of such CAR-T cells administered in a monotherapy regimen to an individual with a CD19+ cancer (e.g., a B-cell lymphoma, such as a large B-cell lymphoma of follicular lymphoma) is about 2 x 10 per kg body weight. 6 Up to 2x10 CAR-positive live T cells 8 However, in combination therapy with TMP, a smaller number of live CAR-positive T cells can be administered to patients. CAR-T cells, for example, one order of magnitude less, for example, about 2x10 per kg body weight 5 Up to 2x10 CAR-positive live T cells 7 CAR-positive live T cells, about 2x10 per kg body weight 4 Up to 2x10 CAR-positive live T cells 6 CAR-positive live T cells or about 2x10 per kg body weight 3 Up to 2x10 CAR-positive live T cells 5 In this way, when administering The need for lymphocyte depletion prior to CAR-T cell administration can be reduced or substantially eliminated. After CAR-T cells, recombinant IL-2 (such as aldesleukin The need for treatment with ) can also be reduced or substantially eliminated. CAR-T cells can also reduce the amount of One or more adverse side effects associated with CAR-T cells (e.g., cytokine release syndrome and / or neurotoxicity). or ) and future approved CAR-T therapies, similar results and benefits may be achieved by administering a smaller amount of TMP (e.g., an amount of CAR-T cells that is at least one order of magnitude, at least two orders of magnitude, or at least three orders of magnitude less than the amount specified in the FDA-approved package insert).

[0253] In some cases, the methods disclosed herein for treating cancer do not include a lymphocyte depletion regimen. In other words, in some cases, the individual receiving mCTL therapy does not undergo lymphocyte depletion chemotherapy. Lymphocyte depletion chemotherapy may include administration of, for example, cyclophosphamide and fludarabine prior to infusion of T cells (e.g., 2 to 7 days prior to infusion of T cells).

[0254] In some cases, the methods of the present disclosure for treating cancer do not include administering recombinantly produced IL-2, such as aldesleukin, after administering mCTLs.

[0255] In some cases, the methods of the present disclosure for treating cancer do not include (i) a lymphocyte depletion regimen or (ii) administration of recombinantly produced IL-2, such as aldesleukin, after administration of mCTLs.

[0256] An amount of mCTL can be administered to an individual in need via any of a variety of administration routes. For example, a composition comprising mCTL can be administered via an intramuscular, intravenous, peritumoral, or intratumoral administration route. Similarly, when TMP is administered to an individual, TMP can be administered to the individual via any of a variety of administration routes. For example, a composition comprising TMP (or dimerized TMP) can be administered via an intramuscular, intravenous, peritumoral, or intratumoral administration route.

[0257] Combination therapy

[0258] In some cases, the method disclosed herein for treating cancer in an individual comprises: a) administering mCTL to the individual; and b) administering at least one other therapeutic agent or therapeutic treatment to the individual. In some cases, the method disclosed herein for treating cancer in an individual comprises: a) administering mCTL and TMP to the individual; and b) administering at least one other therapeutic agent or therapeutic treatment to the individual. In some cases, the method disclosed herein for treating cancer in an individual comprises: a) administering mCTL and TMP to the individual; b) administering TMP to the individual; and c) administering at least one other therapeutic agent or therapeutic treatment to the individual. Suitable other therapeutic agents include, but are not limited to, small molecule cancer chemotherapeutics and immune checkpoint inhibitors. Suitable other therapeutic treatments include, for example, radiation therapy, surgery (e.g., surgical removal of a tumor), and the like.

[0259] The treatment method disclosed herein may include co-administering CART-MP and at least one other therapeutic agent. "Co-administration" means administering CART-MP and at least one other therapeutic agent to an individual (although not necessarily at the same time) to achieve a therapeutic effect, which is the result of administering CART-MP and at least one other therapeutic agent. The administration of CART-MP and at least one other therapeutic agent may be substantially simultaneous, for example, within about 1 minute to about 24 hours (e.g., within about 1 minute, within about 5 minutes, within about 15 minutes, within about 30 minutes, within about 1 hour, within about 4 hours, within about 8 hours, within about 12 hours, or within about 24 hours) of administering at least one other therapeutic agent to an individual. In some cases, CART-MP is administered to an individual who is undergoing treatment with at least one other therapeutic agent or has undergone treatment with at least one other therapeutic agent. The administration of CART-MP may occur at different times and / or at different frequencies.

[0260] For example, the treatment method disclosed herein may include co-administration of CART-MP and immune checkpoint inhibitors (such as antibodies specific to immune checkpoints). "Co-administration" means administering both CART-MP and immune checkpoint inhibitors (e.g., antibodies specific to immune checkpoint polypeptides) to an individual to achieve a therapeutic effect, which is the result of administering both CART-MP and immune checkpoint inhibitors (e.g., antibodies specific to immune checkpoint polypeptides). The administration of CART-MP and immune checkpoint inhibitors (e.g., antibodies specific to immune checkpoint polypeptides) may be substantially simultaneous, for example, within about 1 minute to about 24 hours (e.g., within about 1 minute, within about 5 minutes, within about 15 minutes, within about 30 minutes, within about 1 hour, within about 4 hours, within about 8 hours, within about 12 hours, or within about 24 hours, within 1 week, within 3 weeks, within 3 weeks, within four weeks, or within one month) after administering immune checkpoint inhibitors (e.g., antibodies specific to immune checkpoint polypeptides). In some cases, the CART-MP of the present disclosure is administered to an individual who is undergoing treatment with an immune checkpoint inhibitor (e.g., an antibody specific for an immune checkpoint polypeptide) or has undergone treatment with an immune checkpoint inhibitor (e.g., an antibody specific for an immune checkpoint polypeptide). Administration of CART-MP and immune checkpoint inhibitors (e.g., antibodies specific for immune checkpoint polypeptides) may occur at different times and / or at different frequencies. If the checkpoint inhibitor has an established dosing interval, the CART-MP may be administered on the same day as the checkpoint inhibitor, depending on the interval. For example, in some cases, where the dosing schedule for pembrolizumab is once every three weeks, a pharmaceutical composition comprising a CART-MP may be administered on the same day.

[0261] Exemplary immune checkpoint inhibitors include targeted immune checkpoint polypeptides, such as CD27, CD28, CD40, CD122, CD96, CD73, CD47, OX40, GITR, CSF1R, JAK, PI3Kδ, PI3Kγ, TAM, arginase, CD137 (also known as 4-1BB), ICOS, A2AR, B7-H3, B7-H4, BTLA, CTLA-4, LAG3, TIM3, VISTA, CD96, TIGIT, CD122, PD-1, PD-L1 and PD-L2 inhibitors. In some cases, immune checkpoint polypeptides are selected from the following stimulating checkpoint molecules: CD27, CD28, CD40, ICOS, OX40, GITR, CD122 and CD137. In some cases, the immune checkpoint polypeptide is an inhibitory checkpoint molecule selected from the group consisting of A2AR, B7-H3, B7-H4, BTLA, CTLA-4, IDO, KIR, LAG3, PD-1, TIM3, CD96, TIGIT, and VISTA.

[0262] In some cases, immune checkpoint inhibitors are antibodies specific to immune checkpoint polypeptides. In some cases, anti-immune checkpoint antibodies are monoclonal antibodies. In some cases, anti-immune checkpoint antibodies are humanized, or deimmunized, so that the antibody does not substantially cause an immune response in the human body. In some cases, anti-immune checkpoint antibodies are humanized monoclonal antibodies. In some cases, anti-immune checkpoint antibodies are deimmunized monoclonal antibodies. In some cases, anti-immune checkpoint antibodies are fully human monoclonal antibodies. In some cases, anti-immune checkpoint antibodies inhibit the binding of immune checkpoint polypeptides to the ligands of immune checkpoint polypeptides. In some cases, anti-immune checkpoint antibodies inhibit the binding of immune checkpoint polypeptides to the receptors of immune checkpoint polypeptides.

[0263] Suitable anti-immune checkpoint antibodies include, but are not limited to, nivolumab (Bristol-Myers Squibb), pembrolizumab (Merck), pidilizumab (Curetech), AMP-224 (GlaxoSmithKline / Amplimmune), MPDL3280A (Roche), MDX-1105 (Medarex, Inc. / Bristol-Myer Squibb), MEDI-4736 (Medimmune / AstraZeneca), arelumab (Merck Serono), ipilimumab (YERVOY, (Bristol-Myers Squibb), tremelimumab (Pfizer), pidilizumab (CureTech, Ltd.), IMP321 (Immutep SA), MGA271 (Macrogenics), BMS-986016 (Bristol-Meyers Squibb), lirilumab (Bristol-Myers Squibb), urelumab (Bristol-Meyers Squibb), PF-05082566 (Pfizer), IPH2101 (Innate Pharma / Bristol-Myers Squibb), MEDI-6469 (MedImmune / AZ), CP-870,893 (Genentech), Mogamulizumab (Kyowa HakkoKirin), Varlilumab (CelIDex Therapeutics), Avelumab (EMDSerono), Galiximab (Biogen Idec), AMP-514 (Amplimmune / AZ), AUNP 12 (Aurigene and Pierre In some cases, the immune checkpoint inhibitor is an anti-PD-1 antibody. Suitable anti-PD-1 antibodies include, for example, nivolumab, pembrolizumab (also known as MK-3475), pidilizumab, SHR-1210, PDR001, and AMP-224.In some cases, the anti-PD-1 monoclonal antibody is nivolumab, pembrolizumab or PDR001. Suitable anti-PD1 antibodies are described in U.S. Patent Publication No. 2017 / 0044259. For pidilizumab, see, for example, Rosenblatt et al. (2011) J.Immunother.34:409-18. In some cases, the immune checkpoint inhibitor is an anti-CTLA-4 antibody. In some cases, the anti-CTLA-4 antibody is ipilimumab or tremelimumab. For tremelimumab, see, for example, Ribas et al. (2013) J.Clin.Oncol.31:616-22. In some cases, the immune checkpoint inhibitor is an anti-PD-L1 antibody. In some cases, the anti-PD-L1 monoclonal antibody is BMS-935559, MEDI4736, MPDL3280A (also known as RG7446), KN035 or MSB0010718C.

For atezolizumab, see, e.g., U.S. Patent No. 8,217,149. In some cases, the immune checkpoint inhibitor is an anti-TIGIT antibody that can bind to a T cell immune receptor (TIGIT) having an immunoglobulin and ITIM domain. In some cases, the anti-TIGIT antibody is BMS-986207 (Bristol-Myers Squibb). In some cases, the anti-TIGIT antibody is tiragolumab. In some cases, the anti-TIGIT antibody is EOS88448 (EOS-448). See, e.g., USPN 11,008,390 and USPN 10,189,902; U.S. Patent Publication No. 2017 / 0088613; and WO 2019 / 137541.
