[0005] This disclosure provides a recombinant T-cell receptor (“TCR”) that specifically binds to human gp100 and its uses. Background of the Invention

[0007] Immunotherapy has emerged as a key tool in the fight against a variety of diseases, including cancer. T-cell therapy is at the forefront of immunotherapy development, and adoptive transfer of anti-tumor T cells has been shown to induce clinical responses in cancer patients. Although many T-cell therapies target mutated tumor antigens, the vast majority of neoantigens are not common to each patient but are unique.

[0008] The number of potential non-mutated antigens exceeds that of mutated antigens by several orders of magnitude. Elucidating T-cell epitopes derived from shared antigens could facilitate the robust development of effective and safe adoptive T-cell therapies readily available to a large population of cancer patients. However, the absolute number of non-mutated antigens and the high polymorphism of HLA genes may have hindered a comprehensive analysis of the specificity of anti-tumor T-cell responses to non-mutated antigens.

[0009] This disclosure provides novel epitopes of the nonmutated antigen gp100 and TCRs capable of specifically binding to said epitopes. These novel epitopes are associated with specific HLA alleles. The use of these tumor-responsive HLA-restricted gp100 TCRs supports the applicability of broadened anti-gp100 TCR gene therapy, particularly in immuno-oncology. Summary of the Invention

[0066] The term “about” is used herein to mean approximately, roughly, about, or near. When the term “about” is used in conjunction with a numerical range, it modifies the range by expanding the boundaries above and below the stated value. Generally, the term “about” is used herein to modify values ​​that are higher or lower than the stated value by a deviation of 10% upwards or downwards (higher or lower).

[0067] It should be understood that wherever the word “comprising” is used in this document to describe aspects, other similar aspects described in other ways by the terms “composed of” and / or “substantially composed of” are also provided.

[0068] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. For example, the Concise Dictionary of Biomedicine and Molecular Biology, Juo, Pei-Show, 2nd edition, 2002, CRC Press; The Dictionary of Cell and Molecular Biology, 3rd edition, 1999, Academic Press; and the Oxford Dictionary of Biochemistry and Molecular Biology, revised edition, 2000, Oxford University Press provide those skilled in the art with comprehensive dictionaries of many terms used in this disclosure.

[0069] Units, prefixes, and symbols are represented in their form as accepted by the International System of Units (SI). Numerical ranges include the numbers defining the range. Unless otherwise indicated, nucleotide sequences are written from left to right in a 5' to 3' direction. Amino acid sequences are written from left to right in an amino-to-carboxyl direction. The headings provided herein are not intended to limit the various aspects of this disclosure and may be taken as such by reference to the specification as a whole. Therefore, the terms defined below immediately are defined more fully by reference to this specification in its entirety.

[0070] "Administration" means the physical introduction of an agent into a subject using any of the various methods and delivery systems known to those skilled in the art. Exemplary routes of administration for the formulations disclosed herein include intravenous, intramuscular, subcutaneous, intraperitoneal, spinal, or other parenteral administration routes, such as by injection or infusion. As used herein, the phrase "parenteral administration" refers to a mode of administration other than enteral and local administration, typically by injection, and includes, but is not limited to, intravenous, intramuscular, intraarterial, intrasheath, intralymphatic, intralesional, intracapsular, intracardiac, intradermal, intraperitoneal, tracheal, subcutaneous, subepidermal, intra-articular, subcapsular, subarachnoid, intraspinal, epidural, and intrasternal injections and infusions, as well as in vivo electroporation. In some embodiments, the formulation is administered via a non-parenteral route (e.g., orally). Other non-parenteral routes include local, transdermal, or transmucosal administration routes, such as intranasal, vaginal, rectal, sublingual, or local administration. It can also be applied, for example, once, multiple times, and / or over one or more extended time periods.

[0071] As used herein, the term “T cell receptor” (TCR) refers to a heterogeneous cell surface receptor capable of specifically interacting with a target antigen. As used herein, “TCR” includes, but is not limited to, naturally occurring and non-naturally occurring TCRs; full-length TCRs and their antigen-binding portions; chimeric TCRs; TCR fusion constructs; and synthetic TCRs. In humans, TCRs are expressed on the surface of T cells and are responsible for T cell recognition and targeting by antigen-presenting cells. Antigen-presenting cells (APCs) display fragments of foreign proteins (antigens) that are complexed with the major histocompatibility complex (MHC; also referred to herein as complexed with HLA molecules, such as HLA class 1 molecules). TCRs recognize and bind to the antigen:HLA complex and recruit CD3 (expressed by T cells), thereby activating the TCR. Activated TCRs initiate downstream signaling and immune responses, including the disruption of EPCs.

[0072] Generally, a TCR may consist of two chains interconnected by disulfide bonds, an α-chain and a β-chain (or less commonly, a γ-chain and a δ-chain). Each chain contains variable domains (α-chain variable domains and β-chain variable domains) and constant regions (α-chain constant regions and β-chain constant regions). The variable domains are located at the distal end of the cell membrane and interact with the antigen. The constant regions are located at the proximal end of the cell membrane. A TCR may also contain a transmembrane region and a short cytoplasmic tail. As used herein, the term "constant region" encompasses both the transmembrane region and the cytoplasmic tail (when present) as well as the conventional "constant region".

[0073] The variable domains can be further subdivided into highly variable regions, called complementarity-determining regions (CDRs), which are scattered with more conserved regions called framework regions (FRs). Each α-chain and β-chain variable domain contains three CDRs and four FRs: FR1, CDR1, FR2, CDR2, FR3, CDR3, and FR4. Each variable domain contains a binding domain that interacts with the antigen. Although all three CDRs on each chain participate in antigen binding, CDR3 is believed to be the primary antigen-binding region. CDR1 also interacts with the antigen, while CD2 is believed to primarily recognize the HLA complex.

[0074] Unless explicitly stated otherwise, and unless the context otherwise indicates, the term “TCR” also includes antigen-binding fragments or portions of any TCR disclosed herein, and includes monovalent and bivalent fragments or portions, and single-chain TCRs. The term “TCR” is not limited to naturally occurring TCRs bound to the surface of T cells. As used herein, the term “TCR” further refers to TCRs expressed on the surface of cells other than T cells (e.g., cells naturally expressed or modified to express CD3 as described herein), or TCRs without a cell membrane as described herein (e.g., isolated TCRs or soluble TCRs).

[0075] "Antigen-binding molecule," "part of TCR," or "TCR fragment" refers to any portion of the TCR smaller than the whole. Antigen-binding molecules may include antigen complementarity-determining regions (CDRs).

[0076] "Antigen" refers to any molecule, such as a peptide, that elicits an immune response or is capable of binding to a TCR. As used herein, "epitope" refers to a portion of a polypeptide that elicits an immune response or is capable of binding to a TCR. An immune response may involve antibody production or activation of cells with specific immune activity, or both. Those skilled in the art will readily understand that any macromolecule, including virtually all proteins or peptides, can act as an antigen. Antigens and / or epitopes may be expressed endogenously, i.e., expressed from genomic DNA, or may be recombinantly expressed. Antigens and / or epitopes may be specific to a particular tissue (such as cancer cells), or they may be widely expressed. Furthermore, fragments of larger molecules may act as antigens. In one embodiment, the antigen is a tumor antigen. Epitopes may be present in longer polypeptides (e.g., proteins), or epitopes may be present as fragments of longer polypeptides. In some embodiments, the epitope is complexed with a major histocompatibility complex (MHC; also referred to herein as complexed with HLA molecules, such as HLA class 1 molecules).

[0077] As used herein, “gp100,” “glycoprotein 100,” “melanocyte protein PMEL,” or “ME20M” refers to a tumor antigen expressed in, for example, melanoma. gp100 is a hydrophobic glycoprotein of 661 amino acids with a molecular weight of 70 kDa (GenBank accession number NM_006928). See, for example, Eisenberg et al., Cell Imunol. 266(1):98-103 (2010). In vivo, gp100 is involved in the maturation of melanosomes from phase I to phase II. As used herein, gp100 refers not only to the full-length canonical sequence but also to its variants and fragments. Known variants of gp100 are available at www.uniprot.org (UniProtKB-P40967; last accessed March 1, 2019).

[0079]

[0080] As used herein, the term "HLA" refers to human leukocyte antigens. HLA genes encode major histocompatibility complex (MHC) proteins in humans. MHC proteins are expressed on cell surfaces and participate in the activation of immune responses. HLA class I genes encode MHC class I molecules, which are expressed on cell surfaces as complexes with peptide fragments (antigens) of self or non-self proteins. T cells expressing TCR and CD3 recognize antigen-MHC class I complexes and initiate immune responses to target and destroy antigen-presenting cells displaying non-self proteins.

[0081] As used herein, "HLA class I molecule" or "HLA class I molecule" refers to the protein product of a wild-type or variant HLA class I gene encoding an MHC class I molecule. Therefore, "HLA class I molecule" and "MHC class I molecule" are used interchangeably in this article.

[0082] MHC class I molecules consist of two protein chains: an α chain and a β2-microglobulin (β2m) chain. Human β2m is encoded by the B2M gene. The amino acid sequence of β2m is described in SEQ ID NO:16 (Table 2). The α chain of MHC class I molecules is encoded by the HLA gene complex. The HLA complex is located in the 6p21.3 region on the short arm of human chromosome 6 and contains more than 220 genes with multiple functions. The HLA gene is highly variable, with more than 20,000 HLA alleles and associated alleles, including more than 15,000 HLA class I alleles known in the art, which encode thousands of HLA proteins, including more than 10,000 HLA class I proteins (see, for example, hla.alleles.org, last accessed February 27, 2019). At least three genes encoding MHC class I α chain proteins are present in the HLA complex: HLA-A, HLA-B, and HLA-C. In addition, HLA-E, HLA-F, and HLA-G encode proteins that associate with MHC class I molecules.

[0084]

[0085] The term "autologous" means any material derived from the same individual as the individual into whom the material is subsequently introduced. For example, autologous T-cell therapy involves administering T cells isolated from the same individual to a subject. The term "allogeneic" means any material derived from an individual and subsequently introduced into another individual of the same species. For example, allogeneic T-cell transplantation involves administering T cells obtained from a donor other than the subject to a subject.

[0086] "Cancer" refers to a wide range of diseases characterized by the uncontrolled growth of abnormal cells in the body. Disordered cell division and growth lead to the formation of malignant tumors that invade adjacent tissues and can also metastasize to distant parts of the body via the lymphatic system or bloodstream. "Cancer" or "cancer tissue" can include tumors. Examples of cancers treatable by the methods of this invention include, but are not limited to, cancers of the immune system, including lymphoma, leukemia, and other white blood cell malignancies. In some embodiments, the method of the present invention can be used to reduce the size of tumors originating from, for example, bone cancer, kidney cancer, prostate cancer, breast cancer, colon cancer, lung cancer, cutaneous or ocular malignant melanoma, pancreatic cancer, skin cancer, head and neck cancer, cutaneous or ocular malignant melanoma, uterine cancer, ovarian cancer, rectal cancer, anal cancer, gastric cancer, testicular cancer, uterine cancer, fallopian tube cancer, endometrial cancer, cervical cancer, vaginal cancer, vulvar cancer, Hodgkin's disease, non-Hodgkin's lymphoma (NHL), primary mediastinal large B-cell lymphoma (PMBC), diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), transformed follicular lymphoma, splenic marginal zone lymphoma (SMZL), esophageal cancer, small bowel cancer, and endocrine system cancers.

Certain cancers may be responsive to chemotherapy or radiation therapy, or the cancer may be refractory. Refractory cancers are those that are not suitable for surgical intervention and that initially do not respond to chemotherapy or radiation therapy or become unresponsive over time.

[0087] As used in this article, "antitumor effect" refers to biological effects that can exist in the following forms: reduction in tumor volume, reduction in the number of tumor cells, reduction in tumor cell proliferation, reduction in the number of metastases, increase in overall survival or progression-free survival, increase in life expectancy, or improvement in various physiological symptoms associated with tumors. Antitumor effect can also refer to the prevention of tumor development, such as through vaccines.

[0091] The term "overall survival" can be abbreviated as OS, which is defined as the time from the date of treatment to the date of death.

[0092] As used herein, "cytokine" refers to a non-antibody protein released by a cell in response to contact with a specific antigen, wherein the cytokine interacts with a second cell to mediate a response in the second cell. Cytokines can be expressed endogenously by cells or administered to a subject. Cytokines can be released by immune cells, including macrophages, B cells, T cells, and mast cells, to propagate an immune response. Cytokines can induce various responses in recipient cells. Cytokines can include homeostatic cytokines, chemokines, pro-inflammatory cytokines, effectors, and acute-phase proteins. For example, homeostatic cytokines, including interleukin (IL)7 and IL-15, promote immune cell survival and proliferation, and pro-inflammatory cytokines can promote inflammatory responses. Examples of homeostatic cytokines include, but are not limited to, IL-2, IL-4, IL-5, IL-7, IL-10, IL-12p40, IL-12p70, IL-15, and interferon (IFN)γ. Examples of pro-inflammatory cytokines include, but are not limited to, IL-1a, IL-1b, IL-6, IL-13, IL-17a, tumor necrosis factor (TNF)-α, TNF-β, fibroblast growth factor (FGF)2, granulocyte-macrophage colony-stimulating factor (GM-CSF), soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular adhesion molecule-1 (sVCAM-1), vascular endothelial growth factor (VEGF), VEGF-C, VEGF-D, and placental growth factor (PLGF).

The ability of a therapeutic agent to promote disease regression can be assessed using a variety of methods known to skilled practitioners, such as in human subjects during clinical trials, in animal model systems that predict efficacy in humans, or by assaying activity in vitro using an assay agent.

[0096] As used herein, the term "lymphocyte" includes natural killer (NK) cells, T cells, or B cells. NK cells are a class of cytotoxic / cell-toxic lymphocytes that represent a major component of the innate immune system. NK cells repel tumor cells and cells infected by viruses. They work through the process of apoptosis, or programmed cell death. They are called "natural killers" because they do not require activation to kill cells. T cells play a major role in cell-mediated immunity (not involving antibodies). The T cell receptor (TCR) distinguishes T cells from other lymphocyte types. The thymus, a specialized organ of the immune system, is primarily responsible for the maturation of T cells. There are six types of T cells: helper T cells (e.g., CD4+ cells), cytotoxic T cells (also known as TC, cytotoxic T lymphocytes, CTL, T-killer cells, cytolytic T cells, CD8+ T cells, or killer T cells), memory T cells ((i) stem cell-like memory T cells), and memory T cells ((i) stem cell-like memory T cells). SCMCells (such as naïve cells) are CD45RO-, CCR7+, CD45RA+, CD62L+ (L-selectin), CD27+, CD28+, and IL-7Rα+, but they also express large amounts of CD95, IL-2Rβ, CXCR3, and LFA-1, and exhibit many of the unique functional characteristics of memory cells; (ii) central memory T cells CM Cells express L-selectin and CCR7, secrete IL-2, but do not secrete IFNγ or IL-4, and (iii) however, effector memory T EM B cells do not express L-selectin or CCR7, but produce effector cytokines such as IFNγ and IL-4, regulatory T cells (Tregs, suppressor T cells, or CD4+CD25+ regulatory T cells), natural killer T cells (NKTs), and γδ T cells. On the other hand, B cells play a major role in humoral immunity (involving antibodies). B cells produce antibodies and antigens and act as antigen-presenting cells (APCs), and become memory B cells after activation through antigen-antigen interactions. In mammals, immature B cells form in the bone marrow, from which the name B cell originates.

[0097] The terms "genetic engineering" or "engineering" refer to methods of modifying the genome of a cell, including but not limited to deleting coding or non-coding regions or portions thereof, or inserting coding regions or portions thereof. In some embodiments, the modified cells are lymphocytes, such as T cells, or modified cells expressing CD3, which may be obtained from a patient or donor. Cells may be modified to express exogenous constructs incorporated into the cell's genome, such as the T cell receptor (TCR) disclosed herein. In some embodiments, cells are modified to express CD3.

[0098] "Immune response" refers to the action of cells of the immune system (such as T lymphocytes, B lymphocytes, natural killer (NK) cells, macrophages, eosinophils, mast cells, dendritic cells, and neutrophils) and soluble macromolecules (including antibodies, cytokines, and complement) produced by any of these cells or the liver, which cause selective targeting, binding, damage, destruction, and / or elimination of invading pathogens, pathogen-infected cells or tissues, cancer cells or other abnormal cells, or normal human cells or tissues in cases of autoimmunity or pathological inflammation in vertebrates.

[0099] The term "immunotherapy" refers to the treatment of a subject who has a disease or is at risk of contracting or relapsing from a disease by means of methods including inducing, enhancing, suppressing, or otherwise altering the immune response. Examples of immunotherapy include, but are not limited to, T-cell therapy. T-cell therapy may include adoptive T-cell therapy, tumor-infiltrating lymphocyte (TIL) immunotherapy, autologous cell therapy, engineered autologous cell therapy (eACT), and allogeneic T-cell transplantation.

[0100] Cells used in the immunotherapy described herein may be derived from any source known in the art. For example, T cells may be distinguishable from hematopoietic stem cell populations in vitro, or T cells may be obtained from the subject. T cells may be obtained from, for example, peripheral blood mononuclear cells, bone marrow, lymph node tissue, umbilical cord blood, thymus tissue, tissue from the site of infection, ascites, pleural effusion, spleen tissue, and tumors. Furthermore, T cells may be derived from one or more T cell lines available in the art. T cells may also be obtained from sources known to those skilled in the art, such as FICOLL. TM Any number of techniques for isolating and / or apheresis of blood components can be used to collect a unit of blood from a subject. Other methods for isolating T cells for T-cell therapy are disclosed in U.S. Patent Publication No. 2013 / 0287748, which is incorporated herein by reference in its entirety. Immunotherapy may also include administering modified cells to a subject, wherein the modified cells express CD3 and the TCR disclosed herein. In some embodiments, the modified cells are not T cells.

[0102] The terms “peptide,” “polypeptide,” and “protein” are used interchangeably and refer to compounds containing amino acid residues covalently linked by peptide bonds. A protein or peptide must contain at least two amino acids, and there is no limit to the maximum number of amino acids in a sequence that may contain a protein or peptide. A polypeptide includes any peptide or protein containing two or more amino acids linked together by peptide bonds. As used herein, the term refers to a short chain, which is also commonly referred to in the art, for example, as a peptide, oligopeptide, and oligomer; and to a longer chain, which is commonly referred to in the art, as a protein, of which there are many types. “Polypeptide” includes, for example, biologically active fragments, substantially homologous polypeptides, oligopeptides, homodimers, heterodimers, polypeptide variants, modified polypeptides, derivatives, analogs, fusion proteins, etc. Polypeptides include natural peptides, recombinant peptides, synthetic peptides, or combinations thereof.

[0103] As used herein, “stimulus” refers to a major response induced by the binding of a stimulating molecule to its homologous ligand, wherein the binding mediates a signal transduction event. A “stimulating molecule” is a molecule on a T cell that specifically binds to a homologous stimulating ligand present on an antigen-presenting cell, such as the T cell receptor (TCR) / CD3 complex. A “stimulating ligand” is a ligand present on an antigen-presenting cell (e.g., aAPC, dendritic cells, B cells, and similar cells) that can specifically bind to a stimulating molecule on a T cell, thereby mediating a major response induced by the T cell, including but not limited to activation, initiation of an immune response, proliferation, and similar reactions. Stimulating ligands include, but are not limited to, peptide-loaded MHC class I molecules, anti-CD3 antibodies, hyperagonist anti-CD28 antibodies, and hyperagonist anti-CD2 antibodies.

[0104] The terms “treatment” and “pretreatment” are used interchangeably herein and refer to preparation for a patient requiring T-cell therapy for an appropriate situation. Treatment as used herein includes, but is not limited to, reducing the number of endogenous lymphocytes prior to T-cell therapy, removing the cytokine sink, increasing serum levels of one or more homeostatic cytokines or pro-inflammatory factors, enhancing the effector function of T cells administered after treatment, enhancing antigen-presenting cell activation and / or availability, or any combination thereof. In one embodiment, “treatment” includes increasing serum levels of one or more cytokines, such as interleukin-7 (IL-7), interleukin-15 (IL-15), interleukin-10 (IL-10), interleukin-5 (IL-5), γ-inducible protein 10 (IP-10), interleukin-8 (IL-8), monocyte chemoattractant protein 1 (MCP-1), placental growth factor (PLGF), C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular adhesion molecule-1 (sVCAM-1), or any combination thereof. In another embodiment, "treatment" includes increasing serum levels of IL-7, IL-15, IP-10, MCP-1, PLGF, CRP, or any combination thereof.

[0105] Treatment / treating of a subject refers to any type of intervention or treatment administered to a subject or to a subject with the aim of reversing, alleviating, improving, suppressing, slowing, or preventing the onset, progression, development, severity, or recurrence of symptoms, complications, or lesions or biochemical markers associated with the disease. In one implementation, treatment / treating includes partial remission. In another implementation, treatment / treating includes complete remission.

[0106] The use of substitution (e.g., "or") should be understood to mean one, both, or any combination of the substitutes. As used herein, the indefinite article "a / kind" should be understood to mean "one / kind or more / kinds" of any of the described or enumerated components.

[0107] The terms “about” or “substantially comprise” refer to a specific value or composition that, as determined by a person skilled in the art, is within an acceptable margin of error, which will depend in part on how the value or composition is measured or determined, i.e., the limitations of the measuring system. For example, “about” or “substantially comprise” may mean within one or more standard deviations according to convention in the art. Alternatively, “about” or “substantially comprise” may mean a range of up to 10% (i.e., ±10%). For example, about 3 mg may include any number between 2.7 mg and 3.3 mg (for 10%). Furthermore, specifically in relation to biological systems or methods, the term may mean up to an order of magnitude or up to five times the value. When specific values ​​or compositions are provided in this application and claims, unless otherwise stated, the meaning of “about” or “substantially comprise” should be assumed to be within an acceptable margin of error for said specific value or composition.

[0108] Unless otherwise stated, as described herein, any concentration range, percentage range, ratio range, or integer range shall be understood to include any integer value within the range and (where appropriate) its fraction (such as tenths and percentes of an integer).

[0109] The various aspects of the invention are described in more detail in the following sections.

[0110] II. Compositions disclosed herein

[0111] This disclosure relates to a T-cell receptor (TCR) or its antigen-binding portion that specifically binds to an epitope on gp100, a nucleic acid molecule encoding said TCR, and a cell containing said TCR or said nucleic acid molecule. Some aspects of the invention relate to a method of treating cancer in a subject of need, the method comprising administering to the subject cells containing the TCR described herein. Other aspects of this disclosure relate to an epitope of gp100 that binds to a TCR, and an HLA class I molecule complexed with a peptide containing the gp100 epitope.

[0112] T-cell receptors, or TCRs, are molecules present on the surface of T cells or T lymphocytes that are responsible for recognizing fragments of antigens as peptides that bind to the major histocompatibility complex (MHC) molecule. The binding between TCRs and antigenic peptides has a relatively low affinity and is degenerate: in other words, many TCRs recognize the same antigenic peptides and many antigenic peptides are recognized by the same TCRs.

[0113] The TCR consists of two distinct protein chains (in other words, it is a heterodimer). In humans, in 95% of T cells, the TCR is composed of an α (α) chain and a β (β) chain (encoded by TRA and TRB, respectively), but in 5% of T cells, the TCR is composed of a γ and a δ (γ / δ) chain (encoded by TRG and TRD, respectively). This ratio varies during ontogeny and in disease states (such as leukemia). It also differs between species. Orthologs of four loci have been located in various species. Each locus can produce a variety of polypeptides with constant and variable regions.

[0114] When the TCR binds to the antigenic peptide and MHC (peptide / MHC), T lymphocytes are activated through signal transduction, which is a series of biochemical events mediated by related enzymes, co-receptors, specialized adaptor molecules, and activated or released transcription factors.

[0115] II.A. Nucleic acid molecules

[0116] Certain aspects of this disclosure relate to nucleic acid molecules comprising (i) a first nucleotide sequence encoding a recombinant TCR or its antigen-binding portion (“anti-gp100 TCR”) that specifically binds to human gp100; and (ii) a second nucleotide sequence, wherein the second nucleotide sequence or a polypeptide encoded by the second nucleotide sequence inhibits the expression of an endogenous TCR. In some embodiments, the second nucleotide sequence is a non-naturally occurring sequence. In other embodiments, the second nucleotide sequence is synthetic. In other embodiments, the second nucleotide sequence comprises a sequence of nucleotides targeting and encoding an endogenous TCR. In some embodiments, the anti-gp100 TCR cross-competitively binds to human gp100 with a reference TCR. In some embodiments, the anti-gp100 TCR binds to the same or overlapping epitopes of human gp100 as the reference TCR.

[0117] In some embodiments, the reference TCR comprises an α chain and a β chain; wherein the α chain comprises complementarity-determining regions 1 (CDR1), CDR2, and CDR3; wherein the β chain comprises CDR1, CDR2, and CDR3; and wherein the reference TCR comprises the α chain CDR3 listed in SEQ ID NO:7 and the β chain CDR3 listed in SEQ ID NO:10. In some embodiments, the α chain CDR1, CDR2, and CDR3 sequences are present in the amino acid sequence listed in SEQ ID NO:1, and the reference TCR comprises the β chain CDR1, CDR2, and CDR3 sequences present in the amino acid sequence listed in SEQ ID NO:2. In some embodiments, the reference TCR comprises an α chain and a β chain, wherein the α chain comprises the amino acid sequence listed in SEQ ID NO:1 and the β chain comprises the amino acid sequence listed in SEQ ID NO:2.

[0133] II.A.2. Epitope

[0134] In some embodiments, the anti-gp100 TCR encoded by the first nucleotide sequence binds to the same epitope as the reference TCR. In some embodiments, the anti-gp100 TCR binds to an epitope of gp100 comprising the amino acid sequence listed in SEQ ID NO:13 (RYGSFSVTL). In some embodiments, the anti-gp100 TCR binds to an epitope of gp100 consisting of an amino acid sequence as listed in SEQ ID NO:13. In some embodiments, the epitope consists of amino acid residues 479-487 (SEQ ID NO:52) of gp100, for example, “gp100”. 479-487 ".

[0135] In some implementations, the epitope is complexed with an HLA class I molecule. The human leukocyte antigen (HLA) system (the major histocompatibility complex [MHC] in humans) is an important part of the immune system and is controlled by genes located on chromosome 6. It encodes cell surface molecules that are specialized to present antigenic peptides to T cell receptors (TCRs) on T cells. (See also Overview of the Immune System.) Antigen-presenting MHC molecules are divided into two main classes: class I MHC molecules and class II MHC molecules.

[0136] Class I MHC molecules exist as transmembrane glycoproteins on the surface of all nucleated cells. A complete class I molecule consists of an α-heavy chain bound to a β-2 microglobulin molecule. The heavy chain comprises two peptide-binding domains, an Ig-like domain, and a transmembrane region with a cytoplasmic tail. The heavy chain of class I molecules is encoded by genes at the HLA-A, HLA-B, and HLA-C loci. T cells expressing CD8 molecules respond to class I MHC molecules. These lymphocytes often possess cytotoxic functions, thus requiring the ability to recognize any infected cells. Because every nucleated cell expresses class I MHC molecules, all infected cells can act as antigen-presenting cells for CD8 T cells (CD8 binds to the non-polymorphic portion of the class I heavy chain). Some class I MHC genes encode non-classical MHC molecules, such as HLA-G (which plays a role in protecting the fetus from maternal immune responses) and HLA-E (which presents peptides to certain receptors on natural killer (NK) cells).

[0137] In some embodiments, HLA class 1 molecules are selected from HLA-A, HLA-B, and HLA-C alleles. In some embodiments, HLA class 1 molecules are selected from HLA-E, HLA-F, and HLA-G alleles. In some embodiments, HLA class 1 molecules are HLA-A alleles. In some embodiments, HLA class 1 molecules are HLA-B alleles. In some embodiments, HLA class 1 molecules are HLA-C alleles.

[0138] Many HLA-A, HLA-B, and HLA-C alleles are known in the art, and any of the known alleles may be used in this disclosure. An updated list of HLA alleles is available at hla.alleles.org / (last accessed February 27, 2019). In some embodiments, the HLA class 1 molecule is selected from the following HLA-C alleles: HLA-C*01, HLA-C*02, HLA-C*03, HLA-C*04, HLA-C*05, HLA-C*06, HLA-C*07, HLA-C*08, HLA-C*12, HLA-C*14, HLA-C*15, HLA-C*16, HLA-C*17, and HLA-C*18. In some embodiments, the HLA-C allele is the HLA-C*07:01 allele. In some embodiments, the HLA-C allele is the HLA-C*07:02 allele. In some embodiments, the HLA-C allele is the HLA-C*07:03 allele. In some embodiments, the HLA-C allele is the HLA-C*07:04 allele. In some embodiments, the HLA-C allele is the HLA-C*07:05 allele. In some embodiments, the HLA-C allele is the HLA-C*07:06 allele. In some embodiments, the HLA-C allele is the HLA-C*07:07 allele. In some embodiments, the HLA-C allele is the HLA-C*07:08 allele.

[0210] Example

[0211] Example 1

[0212] TILs were isolated from patients with metastatic melanoma, followed by polyclonal expansion in vitro, and their gp100 antigen specificity against the HLA-C*07:01 allele was examined. A combination of structure-based and functional analyses using peptide / HLA (pHLA) multimers was used to measure Ag-specific T cell responses.

[0213] Since pHLA multimer production requires peptides with known and precise sequences, using pHLA multimer-based strategies for high-throughput screening of novel epitope peptides is neither direct nor practical. In addition to structure-based analyses using pHLA multimers, functional analyses can be applied to determine T-cell antigen specificity. Functional analyses were performed using artificial antigen-presenting cells (APCs) that can process and manufacture longer peptides and act as stimulators to present epitope peptides via class I molecules. C*07:01-artificial APCs were pulsed with overlapping peptides (Table 5) covering the full protein of gp100 and used as stimulators in the cytokine ELISPOT assay. After a single controlled stimulation with C*07:01-artificial APCs pulsed with overlapping peptides derived from gp100, C*07:01 showed significant differences in antigen specificity in the IFN-γ ELISPOT assay. + Melanoma TILs show pairs with shared sequences 476 VLYRYGSFSVTLDIV 490 Positive response of two adjacent peptides ( Figure 1 Using a series of mutant deletion peptides, the minimum required peptide epitopes presented by the C*07:01 molecule were identified. 479 RYGSFSVTL 487 HLA-C*07:01 / gp100 was identified. 479-487 T cells, which constitute CD8+ in polyclonal expanded TILs + 0.14% of T cells (Figure 2). After one controlled peptide-specific stimulation with C*07:01-artificial APC, C*07:01 / gp100 479-487 The frequency of T cells increased to 1.2%, ruling out the possibility of a false positive due to a low staining percentage (Figure 2). According to ELISPOT analysis, multimer-positive T cells secreted detectable IFN-γ in an HLA-restricted peptide-specific manner. Figure 3 ).

[0215]

[0216]

[0217]

[0218] Multimer-positive anti-tumor T cells were collected and their TCR genes were molecularly cloned (Figure 4, SEQ ID NO: 1 and 2). The antigen specificity and functional reactivity of the cloned TCRs were validated by multimer staining and ELISPOT assay of TCR-reconstructed T cells. When based on primary T cell reconstruction, C*07:01 / gp100 479-487 TCR-transduced T cells were successfully stained in the homologous multimer condition (Figure 5) and correlated with gp100 presented by surface C*07:01 molecules. 479-487 Peptide strong reaction ( Figure 6 Importantly, these cells were able to recognize tumor cells that naturally express the gp100 gene and are C*07:01-matched and have not undergone peptide pulse treatment (Figure 7). Although ACHN melanoma cells are gp100-negative, they endogenously express the HLA-C*07:01 gene. When the gp100 gene is ectopically expressed, melanoma cells are characterized by C*07:01 / gp100... 479-487 TCR-transduced T cells were successfully recognized. Furthermore, A375 melanoma cells lacking endogenous expression of C*07:01 and gp100 became C*07:01 / gp100 resistant only upon transduction of either the C*07:01 or gp100 gene (but not either gene alone). 479-487 TCR-transduced T cells are reactive (Figures 7-9). These results clearly confirm that C*07:01 / gp100 479-487 TCR-transduced T cells are highly enthusiastic about recognizing tumor cells and are cloned C*07:01 / gp100 479-487 TCR is tumor-responsive.

[0219] Gp100 is one of the promising and well-studied common antigens in bispecific T-cell connective (BiTE) therapy, and clinical trials targeting gp100 have been conducted in patients with metastatic uveal melanoma using IMCgp100, a bispecific bispecific biopharmaceutical containing a soluble TCR that recognizes the gp100 antigen and is fused to scFv anti-CD3, thereby redirecting T-cell lysis of gp100-expressing melanoma cells in the presence of the HLA-A*02:01 molecule. The use of a newly cloned tumor-reactive C*07:01-restricted gp100 TCR gene could broaden the applicability of gp100-targeting BiTE therapy beyond HLA-A*02:01-positive cancer patients.

[0220] method

[0221] Cell samples

[0222] Peripheral blood samples were obtained from healthy donors after approval by the institutional review board. Monocytes were obtained by density gradient centrifugation (Ficoll-Paque PLUS; GE Healthcare). K562 is an erythroleukemia cell line with defective HLA expression. Jurkat 76 is a T-cell leukemia cell line lacking TCR and CD8 expression. The ACHN cell line was grown in EMEM supplemented with 10% FBS and 50 μg / ml gentamicin. The A375 cell line was grown in DMEM supplemented with 10% FBS and 50 μg / ml gentamicin. The K562 and Jurkat 76 cell lines were cultured in RPMI 1640 supplemented with 10% FBS and 50 μg / ml gentamicin. TILs isolated from metastatic melanoma patients were grown in vitro.

[0223] peptides

[0224] The synthetic peptides were dissolved in DMSO to a concentration of 50 μg / ml. The peptides used were 20-mer overlapping peptides used to cover the full protein of gp100 (Table 1) and C*07:01-restricted gp100. 479-487 (RYGSFSVTL; SEQ ID NO:13), gp100 479-486 (RYGSFSVT; SEQ ID NO:194) and HIV nef 105-115 (KRQDILDLWVY; SEQ ID NO:63) peptide. Using gp100 479-486 and HIV nef 105-115 Peptides were used as negative controls.

[0225] Gene

[0226] The HLA-C*07:01 gene was fused to a truncated form of human nerve growth factor receptor (ΔNGFR) via an internal ribosome entry site. ΔNGFR-transduced cells were isolated using an anti-NGFR monoclonal antibody (mAb). The full-length gp100 gene was purchased from Dharmacon (Lafayette, CO). The TCR gene was cloned using the SMARTer RACE cDNA amplification kit (Takara Bio) via 5'-terminal rapid amplification (RACE) PCR. The 5'-RACE PCR product was cloned into a retroviral vector and sequenced. All genes were cloned into the pMX retroviral vector and transduced using a 293GPG cell-based retroviral system.

[0227] transfectants

[0228] As previously reported, Jurkat 76 / CD8 cells were transduced with individual TCRα and TCRβ genes. 42-44 TCR transfectants derived from Jurkat 76 / CD8 were purified (>95% purity) using CD3 microbeads (Miltenyi Biotec). Previously, K562-based artificial APCs have been reported to express various HLA class I genes as single HLA alleles bound to CD80 and CD83 (Butler and Hirano, Immunol.
