[0003] [Introduction] The present disclosure provides novel dominant-negative Fas polypeptides comprising a first modification in the cytoplasmic domain of human Fas and a second modification in the N-terminal region. The present disclosure also provides cells comprising such novel dominant-negative Fas polypeptides and an antigen-recognition receptor (e.g., a chimeric antigen receptor (CAR) or a T cell receptor (TCR)). Also provided are therapeutic uses of the cells, e.g., for treating tumors and pathogen infections. [Background technology]
[0004] Adoptive cellular immunotherapy using genetically modified autologous or allogeneic T cells and NK cells has shown evidence of therapeutic efficacy for a range of human cancers, including but not limited to melanoma and various B-cell malignancies. T cells can be engineered to target tumor-associated antigens by introducing genes encoding receptors, e.g., chimeric antigen receptors (CARs) or T cell receptors (TCRs), that convey specificity for antigens expressed by cancer or virus-infected cells. Such engineered immune cells represent a type of targeted immunotherapy that may offer treatment for cancer or infectious diseases.
[0005] Adoptive cell transfer (ACT) using genetically modified T cells has become the standard of care for patients with refractory B-cell malignancies, including pediatric acute lymphoblastic leukemia (1) and adult aggressive B-cell lymphoma (2). The exceptional efficacy of ACT in hematolymphoid malignancies has been consistently observed in clinical trials, regardless of the institution, gene vector, or cell composition (3-8). In contrast, responses to adoptive immunotherapy in patients with solid malignancies, which together represent the leading cause of cancer-related deaths in adults (9), have been relatively modest (10-13). Therefore, there remains a need for novel strategies to enhance the efficacy of transferred T cells. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION
[0039] The presently disclosed subject matter provides novel dominant-negative Fas polypeptides and cells comprising such polypeptides. In certain embodiments, the cells further comprise an antigen-recognition receptor (e.g., a TCR or CAR). The presently disclosed subject matter also provides methods of using such cells to treat and / or prevent neoplasms and pathogen infections. The presently disclosed subject matter is based, at least in part, on the discovery that the presence of modifications in the N-terminal region of a dominant-negative Fas polypeptide increases surface expression of the dominant-negative Fas polypeptide by cells, and / or increases the transduction efficiency of the dominant-negative Fas polypeptide into cells, and / or increases the protection of the dominant-negative Fas polypeptide from FasL-induced apoptosis.
[0040] 1.Definition Unless defined herein, all technical and scientific terms used in this detailed description have the meanings commonly understood by those skilled in the art of immuno-oncology, as reflected in the general definitions of many terms used in the subject matter of this disclosure contained, for example, in one or more of the following: Singleton et al., Dictionary of Microbiology and Molecular Biology (2nd ed. 1994); The Cambridge Dictionary of Science and Technology (Walker, ed., 1988); The Glossary of Genetics, 5th ed., R. Rieger et al. (eds.), Springer Verlag (1991); and Hale and Marham, The Harper Collins Dictionary of Biology (1991).
[0041] As used herein, the term "about" or "approximately" means within an acceptable error range for a particular value, as determined by one of ordinary skill in the art, and will depend in part on how the value is measured or determined, i.e., the limitations of the measurement system. For example, "about" can mean within 3 or more standard deviations, in accordance with practice in the art. Alternatively, "about" can mean within a range of up to 20%, e.g., up to 10%, up to 5%, or up to 1% of a given value. Alternatively, particularly with respect to biological systems or processes, the term can mean within an order of magnitude of a value, e.g., within 5-fold or 2-fold of a value.
[0042] By "immunoresponsive cell" is meant a precursor cell or its progeny, including cells that function in an immune response or that initiate, activate, and / or regulate (increase or decrease) an immune response.
[0043] "Activating an immunoresponsive cell" refers to the induction of signal transduction or changes in protein expression in a cell that result in the initiation of an immune response. For example, clustering of CD3 chains in response to ligand binding and immunoreceptor tyrosine-based inhibitory motifs (ITAMs) generates a signaling cascade. In certain embodiments, binding of a TCR or CAR to an antigen leads to the formation of an immune synapse, which involves the clustering of many molecules (e.g., CD4 or CD8, CD3γ / δ / ε / ζ, etc.) near the bound receptor. This clustering of membrane-bound signaling molecules allows for the phosphorylation of ITAM motifs contained within the CD3 chains. This phosphorylation, in turn, initiates the T cell activation pathway, ultimately activating transcription factors such as NF-κB and AP-1. These transcription factors induce expression of all genes in T cells to initiate a T cell-mediated immune response, increasing IL-2 production for proliferation and expression of master regulatory T cell proteins.
[0044] "Stimulating immunoresponsive cells" refers to signals that result in a robust and long-lasting immune response. In various embodiments, this occurs after activation of immune cells (e.g., T cells) or is mediated simultaneously through receptors including, but not limited to, CD28, CD137 (4-1BB), OX40, CD40, and ICOS. While receiving multiple stimulatory signals can be important for initiating a robust and long-lasting T cell-mediated immune response, T cells that receive multiple stimulatory signals can quickly become inhibited and unresponsive to antigen, a state commonly referred to as "exhaustion." While the effects of these costimulatory signals can vary, they generally result in increased gene expression to generate long-lived, proliferative, and anti-apoptotic T cells that robustly respond to antigen for complete and sustained eradication.
[0045] As used herein, the term "antigen-recognizing receptor" refers to a receptor that can activate an immunoresponsive cell (e.g., a T cell) in response to its binding to an antigen. Non-limiting examples of antigen-recognizing receptors include natural or endogenous T cell receptors ("TCRs") and chimeric antigen receptors ("CARs").
[0046] As used herein, the term "antibody" refers not only to intact antibody molecules but also to fragments of antibody molecules that retain antigen-binding ability. Such fragments are also well known in the art and are commonly used both in vitro and in vivo. Thus, as used herein, the term "antibody" refers not only to intact immunoglobulin molecules but also to the well-known active fragments F(ab')2 and Fab. F(ab')2 and Fab fragments, which lack the Fe fragment of intact antibodies, clear more rapidly from the circulation and may have less nonspecific tissue binding than intact antibodies (Wahl et al., J. Nucl. Med. 24:316-325 (1983)). As used herein, the term "antibody" encompasses whole natural antibodies, bispecific antibodies, chimeric antibodies, Fab, Fab', single-chain V-region fragments (scFv), and fusion polypeptides.
[0047] As used herein, the term "complementarity determining region" or "CDR" refers to the hypervariable regions of immunoglobulin heavy and light chain amino acid sequences. See, e.g., Kabat et al., Sequences of Proteins of Immunological Interest, 4th USDapartment of Health and Human Services, National Institutes of Health (1987). Generally, antibodies contain three heavy chain and three light chain CDRs or CDR regions in the variable region. The CDRs provide the majority of contact residues for binding the antibody to its cognate antigen or epitope. In certain embodiments, CDR regions are numbered using the Kabat system (Kabat, EA et al. (1991) Sequences of Proteins of Immunological Interest, 5th ed., USDapartment of Health and Human Services, NIH Publication No. 91-3242).

See also U.S. Patent Nos. 5,091,513, 5,132,405, and 4,956,778; and U.S. Patent Application Publication Nos. 20050196754 and 20050196754. Antagonistic scFvs with inhibitory activity have been described (see, e.g., Zhao et al., Hyrbidoma (Larchmt) 2008 27(6):455-51; Peter et al., J Cachexia Sarcopenia Muscle 2012 August 12; Shieh et al., J Imunol 2009 183(4):2277-85; Giomarelli et al., Thromb Haemost 2007 97(6):955-63; Fife et al., J Clin Invst 2006 116(8):2252-61; Brocks et al., Immunotechnology 1997 3(3):173-84; Moosmayer et al., The Immunol 1995 2(10:31-40)). Agonistic scFvs with stimulatory activity have been described (see, e.g., Peter et al., J Biol Chem 2003 25278(38):36740-7; Xie et al., Nat Biotech 1997 15(8):768-71; Ledbetter et al., Crit Rev Immunol 1997 17(5-6):427-55; Ho et al., BioChim Biophys Acta 2003 1638(3):257-66).
[0049] As used herein, the term "affinity" refers to a measure of binding strength. Affinity may depend on the closeness of the stereochemical fit between the antibody binding site and the antigenic determinant, the size of the contact area between them, and / or the distribution of charged and hydrophobic groups. Methods for calculating the affinity of an antibody for an antigen are known in the art, including, but not limited to, various antigen binding experiments, such as functional assays (e.g., flow cytometry assays).
[0050] As used herein, the term "chimeric antigen receptor" or "CAR" refers to a molecule (e.g., a synthetic receptor) that comprises an extracellular antigen-binding domain fused to an intracellular signaling domain that can activate or stimulate immunoresponsive cells. In certain embodiments, the CAR further comprises a transmembrane domain. In certain embodiments, the extracellular antigen-binding domain of the CAR comprises an scFv. The scFv can be derived from the fusion of the variable heavy and light chain regions of an antibody. In certain embodiments, the scFv can be derived from a Fab (e.g., obtained from a Fab library instead of from an antibody). In certain embodiments, the scFv is fused to a transmembrane domain, which is then fused to an intracellular signaling domain. In certain embodiments, the CAR is selected to have high binding affinity, or avidity, for the antigen.
[0051] As used herein, the term "nucleic acid molecule" includes any nucleic acid molecule encoding a polypeptide of interest (e.g., a dominant-negative Fas polypeptide or an antigen-recognizing receptor) or a fragment thereof. Such a nucleic acid molecule need not be 100% homologous or identical to an endogenous nucleic acid sequence, but may exhibit substantial identity. A polynucleotide having "substantial identity" or "substantial homology" to an endogenous sequence is typically capable of hybridizing to at least one strand of a double-stranded nucleic acid molecule.
[0052] As used herein, the term "conservative sequence modification" refers to an amino acid modification in a protein in which an amino acid having specific physicochemical properties is replaced with another amino acid having the same physicochemical properties (e.g., replacing one basic amino acid with another). In certain embodiments, such substitutions are unlikely to significantly affect the activity of the protein (e.g., conservative substitutions in antibody CDRs are unlikely to significantly affect or change the binding properties of the protein). Modifications can be introduced into the human scFv of the CAR of the present disclosure by standard techniques known in the art, such as site-directed mutagenesis and PCR-mediated mutagenesis. Amino acids can be classified into groups according to their physicochemical properties, such as charge and polarity. In certain embodiments, conservative modifications are conservative amino acid substitutions. Conservative amino acid substitutions are substitutions in which an amino acid residue is replaced with an amino acid within the same group. For example, amino acids can be classified by charge: positively charged amino acids include lysine, arginine, and histidine, negatively charged amino acids include aspartic acid and glutamic acid, and neutrally charged amino acids include alanine, asparagine, cysteine, glutamine, glycine, isoleucine, leucine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine. Additionally, amino acids can be classified by polarity: polar amino acids include arginine (basic polar), asparagine, aspartic acid (acidic polar), glutamic acid (acidic polar), glutamine, histidine (basic polar), lysine (basic polar), serine, threonine, and tyrosine; nonpolar amino acids include alanine, cysteine, glycine, isoleucine, leucine, methionine, phenylalanine, proline, tryptophan, and valine. In certain embodiments, conservative substitutions include substitutions within the following group: glycine, alanine; valine, isoleucine, leucine; aspartic acid, glutamic acid, asparagine, glutamine; serine, threonine; lysine, arginine; and phenylalanine, tyrosine.In certain embodiments, one or more amino acid residues within or outside the CDR regions can be replaced with other amino acid residues from the same group, and the altered antibodies can be tested for retained function (i.e., the functions set forth in (c) through (l) above) using the functional assays described herein. In certain embodiments, no more than 1, no more than 2, no more than 3, no more than 4, or no more than 5 residues outside the CDR regions or within the specified sequences of the CDR regions are altered.
[0053] In certain embodiments, the percent homology between two amino acid sequences is equal to the percent identity between the two sequences. The percent identity between two sequences is a function of the number of identical positions shared by the sequences, taking into account the number of gaps and the length of each gap that need to be introduced for optimal alignment of the two sequences (i.e., % homology = # identical positions / total # positions x 100). The comparison of sequences and determination of percent identity between two sequences can be accomplished using a mathematical algorithm.
[0054] The percent homology or identity between two amino acid sequences can be determined using the E. Meyers and W. Miller (Comput. Appl. Biosci., 4:11-17 (1988)) algorithm incorporated into the ALIGN program (version 2.0) using a PAM120 weight residue table, a gap length penalty of 12, and a gap penalty of 4. Additionally, the percent homology between two amino acid sequences can be determined using the Needleman and Wunsch (J. Mol. Biol. 48:444-453 (1970)) algorithm incorporated into the GAP program in the GCG software package (available at www.gcg.com) using either a Blossum62 matrix or a PAM250 matrix, and gap weights of 16, 14, 12, 10, 8, 6, or 4, and length weights of 1, 2, 3, 4, 5, or 6.
[0055] In certain embodiments, the amino acid sequences of the presently disclosed subject matter can further be used as a "query sequence" to perform a search against public databases, for example, to identify related sequences. Such searches can be performed using the XBLAST program (version 2.0) of Altschul et al. (1990) J. Mol. Biol. 215:403-10. BLAST protein searches can be performed using the XBLAST program, score=50, wordlength=3, to obtain amino acid sequences homologous to the sequences identified herein. To obtain gapped alignments for comparison purposes, Gapped BLAST can be utilized as described in Altschul et al. (1997) Nucleic Acids Res. 25(17):3389-3402. When utilizing BLAST and Gapped BLAST programs, the default parameters of the respective programs (e.g., XBLAST and NBLAST) can be used.
[0056] Furthermore, sequence identity can be measured by using sequence analysis software (e.g., the BLAST, BESTFIT, GAP, or PILEUP / PRETTYBOX programs in the sequence analysis software package of the Genetics Computer Group, University of Wisconsin Biotechnology Center, 1710 University Avenue, Madison, Wis. 53705). Such software matches identical or similar sequences by assigning degrees of homology to various substitutions, deletions, and / or other modifications.
[0057] "Substantially identical" or "substantially homologous" refers to a polypeptide or nucleic acid molecule that exhibits at least about 50% homology or identity to a reference amino acid sequence (e.g., any one of the amino acid sequences set forth herein) or nucleic acid sequence (e.g., any one of the nucleic acid sequences set forth herein). In certain embodiments, such a sequence is at least about 60%, at least about 65%, at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 95%, at least about 99%, or at least about 100% homologous or identical to the amino acid or nucleic acid sequence used for comparison.
[0058] In an exemplary approach to determining the degree of identity, the BLAST program may be used, with a probability score between e-3 and e-100 indicating closely related sequences.
[0059] "Analog" means a structurally related polypeptide or nucleic acid molecule that has the function of a reference polypeptide or nucleic acid molecule.
[0060] As used herein, the term "ligand" refers to a molecule that binds to a receptor. In certain embodiments, a ligand binds to a receptor on another cell, allowing recognition and / or interaction between the cells.
[0061] As used herein, the term "constitutive expression" or "constitutively expressed" refers to expression or being expressed under all physiological conditions.
[0062] By "disease" is meant any condition, disease or disorder that damages or interferes with the normal function of a cell, tissue or organ, for example, neoplasms and pathogenic infections of cells.
[0063] An "effective amount" (or "therapeutically effective amount") is an amount sufficient to affect a beneficial or desired clinical outcome during treatment. An effective amount can be administered to a subject in one or more doses. In terms of treatment, an effective amount is an amount sufficient to palliate, ameliorate, stabilize, reverse, or slow the progression of, or otherwise reduce the pathological consequences of, the disease. An effective amount is generally determined by a physician on a case-by-case basis and is within the skill of one of ordinary skill in the art. Several factors are typically considered when determining the appropriate dosage to achieve an effective amount. These factors include the age, sex, and weight of the subject, the condition being treated, the severity of the condition, and the form and effective concentration of the immunoresponsive cells administered.
[0064] "Enhancing tolerance" means preventing the activity of autoreactive or immunoresponsive cells that target the transplanted organ or tissue.
[0065] "Endogenous" means a nucleic acid molecule or polypeptide that is normally expressed in a cell or tissue.
[0066] "Exogenous" refers to a nucleic acid molecule or polypeptide that is not endogenously present in a cell. Thus, the term "exogenous" will encompass any recombinant nucleic acid molecule or polypeptide expressed in a cell, including foreign, heterologous, and overexpressed nucleic acid molecules and polypeptides. An "exogenous" nucleic acid refers to a nucleic acid that is not present in a native, wild-type cell; for example, an exogenous nucleic acid can differ from its endogenous counterpart by sequence, position / location, or both. For clarity, an exogenous nucleic acid can have the same or a different sequence compared to its native, endogenous counterpart; it can be introduced into the cell itself or its progenitor cell by genetic engineering and can optionally be linked to alternative regulatory sequences, such as non-native promoters or secretory sequences.
[0067] By "heterologous nucleic acid molecule or polypeptide" is meant a nucleic acid molecule (e.g., a cDNA, DNA, or RNA molecule) or polypeptide that is not normally present in a cell or in a sample obtained from a cell. The nucleic acid may be from another organism or may be, for example, an mRNA molecule that is not normally expressed in the cell or sample.
[0068] By "modulate" is meant to alter, either positively or negatively. Exemplary modulations include changes of about 1%, about 2%, about 5%, about 10%, about 25%, about 50%, about 75%, or about 100%.

[0072] The terms "isolated," "purified," or "biologically pure" refer to material that is, to varying degrees, free from components that normally accompany it as found in its native state. "Isolated" indicates a degree of separation from the original source or surroundings. "Purified" indicates a degree of separation greater than isolation. A "purified" or "biologically pure" protein is sufficiently free from other materials so that any impurities do not substantially affect the biological properties of the protein or cause other adverse consequences. That is, a nucleic acid or peptide is purified when it is substantially free of cellular material, viral material, or culture medium if produced by recombinant DNA techniques, or chemical precursors or other chemicals if chemically synthesized. Purity and homogeneity are typically determined using analytical chemistry techniques, such as polyacrylamide gel electrophoresis or high-performance liquid chromatography. The term "purified" can indicate that the nucleic acid or protein gives rise to essentially one band in an electrophoretic gel. In proteins that are subject to modifications, such as phosphorylation or glycosylation, different modifications may result in different isolated proteins that can be purified separately.
[0073] As used herein, the term "antigen-binding domain" refers to a domain that is capable of specifically binding to a particular antigenic determinant or set of antigenic determinants present on a cell.
[0074] As used herein, "linker" is intended to mean a functional group (e.g., a chemical or polypeptide) that covalently joins two or more polypeptides or nucleic acids such that they are linked together. As used herein, a "peptide linker" is a linker that connects two proteins together (e.g., a V H and V L A linker refers to one or more amino acids used to link (connect) domains. In certain embodiments, the linker comprises the sequence set forth in GGGGSGGGSGGGGGS [SEQ ID NO: 1].
[0075] "Neoplasm" refers to a disease characterized by the pathological proliferation of cells or tissues and subsequent migration or invasion of other tissues or organs. Neoplastic growth is typically uncontrolled and progressive, occurring under conditions that would not induce proliferation of normal cells or cause their cessation. Neoplasms can affect a variety of cell types, tissues, or organs, including, but not limited to, organs selected from the group consisting of bladder, bone, brain, breast, cartilage, glia, esophagus, fallopian tubes, gallbladder, heart, intestine, kidney, liver, lung, lymph nodes, nervous tissue, ovaries, pancreas, prostate, skeletal muscle, skin, spinal cord, spleen, stomach, testes, thymus, thyroid, trachea, genitourinary tract, ureter, urethra, uterus, and vagina, or tissues or cell types thereof. Neoplasms include cancers such as sarcomas, carcinomas, or plasmacytomas (malignant tumors of plasma cells).
[0076] By "receptor" is meant a polypeptide or portion thereof present on a cell membrane that selectively binds to one or more ligands.
[0077] "Recognize" refers to selective binding to a target. T cells that recognize tumors can express receptors (e.g., TCRs or CARs) that bind to tumor antigens.
[0078] "Reference" or "control" refers to a standard for comparison. For example, the level of scFv-antigen binding by cells expressing a CAR and an scFv can be compared to the level of scFv-antigen binding in corresponding cells expressing the CAR alone.
[0079] By "secreted" is meant a polypeptide that is released from the cell via the secretory pathway through the endoplasmic reticulum, the Golgi apparatus, and as vesicles that transiently fuse with the cell plasma membrane, releasing the protein outside the cell.
[0080] By "signal sequence" or "leader sequence" is meant a peptide sequence (e.g., 5, 10, 15, 20, 25, or 30 amino acids) present at the N-terminus of newly synthesized proteins that directs their entry into the secretory pathway. Exemplary leader sequences include, but are not limited to, the IL-2 signal sequence: MYRMQLLSCIALSLALVTNS [SEQ ID NO:2] (human), MYSMQLASCVTLTLVLLVNS [SEQ ID NO:3] (mouse); kappa leader sequence: METPAQLLFLLLLWLPDTTG [SEQ ID NO:4] (human), METDTLLLWVLLLWVPGSTG [SEQ ID NO:5] (mouse); CD8 leader sequence: MALPVTALLLPLALLLHAARP [SEQ ID NO:6] (human); truncated human CD8 signal peptide: MALPVTALLLPLALLLHA [SEQ ID NO:7] (human); albumin signal sequence: MKWVTFISLLFSSAYS [SEQ ID NO:8] (human); and prolactin signal sequence: MDSKGSSQKGSRLLLLLVVSNLLLCQGVVS [SEQ ID NO:9] (human). "Soluble" refers to a polypeptide that is freely diffusible (e.g., not membrane-bound) in an aqueous environment.
[0081] By "specifically binds" is meant a polypeptide or fragment thereof that recognizes and binds to a biological molecule of interest (e.g., a polypeptide) but does not substantially recognize or bind to other molecules in a sample, e.g., a biological sample, that naturally contains a polypeptide of the present disclosure.
[0082] The term "tumor antigen" as used herein refers to an antigenic substance produced by tumor cells. Tumor antigens can provoke an immune response in the host. As used herein, the term "tumor antigen" includes tumor-specific antigens (TSAs) and tumor-associated antigens (TAAs). TSAs refer to antigens that are uniquely or differentially expressed on tumor cells compared to normal cells, e.g., present only on tumor cells and not on normal cells. In certain embodiments, tumor antigens include any polypeptide expressed by tumors that can activate or induce an immune response via antigen-recognition receptors (e.g., CD19, MUC-16) or suppress an immune response via receptor-ligand binding (e.g., CD47, PD-L1 / L2, B7.1 / 2). TAAs are antigens that are present on some tumor cells and also on some normal cells.
[0083] The terms "comprises" and "comprising" are intended to have the broad meaning ascribed to them in U.S. patent law and may mean "includes," "including," etc.
[0084] As used herein, "treatment" refers to a clinical intervention that seeks to alter the disease course of the individual or cell being treated, and can be performed for prophylaxis or during the course of clinical pathology. The therapeutic effect of treatment includes, but is not limited to, preventing the onset or recurrence of the disease, alleviating symptoms, reducing any direct or indirect pathological consequences of the disease, preventing metastasis, reducing the rate of disease progression, ameliorating or alleviating the disease state, and remission or improved prognosis. By preventing the progression of a disease or disorder, treatment can prevent progression due to the disorder in an affected or diagnosed subject or a subject suspected of having the disorder, but treatment can also prevent the onset of the disorder or symptoms of the disorder in a subject at risk of or suspected of having the disorder.
[0085] As used herein, an "individual" or "subject" refers to a vertebrate, such as a human or non-human animal, e.g., a mammal. Mammals include, but are not limited to, humans, primates, farm animals, sport animals, rodents, and pets. Non-limiting examples of non-human animal subjects include rodents, such as mice, rats, hamsters, and guinea pigs; pigs; rabbits; dogs; cats; sheep; pigs; goats; cows; horses; and non-human primates, such as apes and monkeys. The term "immunocompromised," as used herein, refers to a subject who is immunocompromised. Subjects are highly vulnerable to opportunistic infections, which are infectious diseases caused by organisms that do not normally cause disease in people with healthy immune systems but can affect people with poorly functioning or suppressed immune systems.
[0086] Other aspects of the presently disclosed subject matter are described in the following disclosure and are within the scope of the presently disclosed subject matter.
[0087] 2. Dominant-negative Fas polypeptide Fas cell surface death receptor (Fas) is also known as APT1; CD95; FAS1; APO-1; FASTM; ALPS1A; TNFRSF6. GenBank ID: 355 (human), 14102 (mouse), 246097 (rat), 282488 (bovine), 486469 (dog). Protein products of Fas include, but are not limited to, NCBI reference sequences NP_000034.1, NP_001307548.1, NP_690610.1, and NP_690611.1.
[0088] Fas is a member of the TNF receptor superfamily and contains a death domain. In human Fas, the death domain is encoded by amino acids 226-319. Fas is involved in the regulation of programmed cell death and has been implicated in the pathogenesis of various malignancies and immune system disorders. The interaction of Fas with its ligands allows the formation of a cell death-inducing signaling complex with other components, such as Fas-associated protein (FADD), which contains a death domain and can induce programmed cell death, also known as apoptosis.
[0089] In certain embodiments, the term "dominant-negative Fas polypeptide" refers to a dominant-negative form of a Fas polypeptide that is the gene product of a dominant-negative mutation of the Fas gene. In certain embodiments, a Fas polypeptide containing a dominant-negative mutation (also called an "antimorph mutation") is an altered gene product that acts antagonistically to a wild-type Fas polypeptide. In certain embodiments, a dominant-negative Fas polypeptide adversely affects a normal, wild-type Fas polypeptide in the same cell. In certain embodiments, a dominant-negative Fas polypeptide interacts with a wild-type Fas polypeptide but blocks its signaling to downstream molecules, e.g., FADD.
[0090] In certain embodiments, the dominant-negative Fas polypeptide comprises a first modification in the intracellular domain of human Fas and a second modification in the N-terminal region. In certain embodiments, the first modification is within the cytoplasmic death domain. In certain embodiments, the first modification prevents binding of Fas to a FADD polypeptide. In certain embodiments, the second modification is located between the peptide signal region and cysteine-rich domain 1 of Fas (e.g., human Fas). In certain embodiments, the peptide signal region of human Fas is encoded by amino acids 1 to 25 of human Fas. In certain embodiments, cysteine-rich domain 1 of human Fas is encoded by amino acids 48 to 82 of human Fas.
[0091] No known function has been described for the region between the peptide signal region and cysteine-rich domain 1 of Fas (e.g., human Fas). Using a CRISPR / Cas9 screen, the inventors discovered that modifications in this region (e.g., truncation of serine 32) enhance Fas cell surface expression. This function is independent of the primary modification and can be combined with dominant-negative Fas polypeptides to further improve their surface expression and dominant-negative function.
[0092] In certain embodiments, human Fas comprises or consists of the amino acid sequence of NCBI Reference No. NP_000034.1 (SEQ ID NO: 10), provided below. In certain embodiments, human Fas polypeptide comprises or consists of an amino acid sequence that is at least about 80%, at least about 85%, at least about 90%, at least about 95%, at least about 96%, at least about 97%, at least about 98%, at least about 99%, or at least about 100% homologous or identical to the amino acid sequence set forth in SEQ ID NO: 10.

[0141] 3.2.T cell receptor (TCR) In certain embodiments, the antigen-recognizing receptor is a TCR. A TCR is a disulfide-linked heterodimeric protein consisting of two variable chains expressed as part of a complex with an invariant CD3 chain molecule. TCRs are found on the surface of T cells and are responsible for recognizing antigens as peptides bound to major histocompatibility complex (MHC) molecules. In certain embodiments, the TCR comprises an alpha chain and a beta chain (encoded by TRA and TRB, respectively). In certain embodiments, the TCR comprises a gamma chain and a delta chain (encoded by TRG and TRD, respectively).
[0142] Each chain of the TCR consists of two extracellular domains, including a variable (V) region and a constant (C) region. The constant region is proximal to the cell membrane and is followed by a transmembrane region and a short cytoplasmic tail that lacks signaling capabilities. The variable region binds to the peptide / MHC complex. The variable domain of each pair of TCR polypeptides (alpha / beta or gamma / delta) contains three complementarity-determining regions (CDRs).
[0143] In certain embodiments, a TCR can form a receptor complex with three dimeric signaling modules, CD3δ / ε, CD3γ / ε, and CD247ζ / ζ or ζ / η. Binding of the TCR complex to its antigen and MHC (peptide / MHC) activates a T cell expressing the TCR complex.
[0144] In certain embodiments, the TCR is an endogenous TCR. In certain embodiments, the TCR recognizes a viral antigen. In certain embodiments, the TCR is expressed in virus-specific T cells. In certain embodiments, the virus-specific T cells are derived from an individual's immunity to a viral infection, e.g., BK virus, human herpesvirus 6, Epstein-Barr virus (EBV), cytomegalovirus, or adenovirus. In certain embodiments, the virus-specific T cells are T cells disclosed in Leen et al., Blood, Vol. 121, No. 26, 2013; Barker et al., Blood, Vol. 116, No. 23, 2010; Tzannou et al., Journal of Clinical Oncology, Vol. 35, No. 31, 2017; or Bollard et al., Blood, Vol. 32, No. 8, 2014, each of which is incorporated by reference in its entirety. In certain embodiments, the TCR recognizes a tumor antigen (including a TAA or TSA). In certain embodiments, the TCR is expressed on tumor-specific T cells. In certain embodiments, the tumor-specific T cells are tumor-infiltrating T cells generated by culturing T cells with tumor, e.g., melanoma or epithelial cancer explants. In certain embodiments, the tumor-specific T cells are T cells disclosed in Stevanovic et al., Science, 356, 200-205, 2017; Dudley et al., Journal of Immunotherapy, 26(4):332-342, 2003; or Goff et al., Journal of Clinical Oncology, Vol. 34, No. 20, 2016, each of which is incorporated by reference in its entirety.
[0145] In certain embodiments, the antigen-recognizing receptor is a recombinant TCR. In certain embodiments, the recombinant TCR differs from any naturally occurring TCR by at least one amino acid residue. In certain embodiments, the non-naturally occurring TCR differs from any naturally occurring TCR by at least about 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 20, 25, 30, 40, 50, 60, 70, 80, 90, 100, or more amino acid residues. In certain embodiments, the non-naturally occurring TCR has been modified from a naturally occurring TCR by at least one amino acid residue. In certain embodiments, a non-naturally occurring TCR has at least about 2, about 3, about 4, about 5, about 6, about 7, about 8, about 9, about 10, about 11, about 12, about 13, about 14, about 15, about 20, about 25, about 30, about 40, about 50, about 60, about 70, about 80, about 90, about 100 or more amino acid residues altered from a naturally occurring TCR.
[0146] 3.3. Chimeric Antigen Receptors (CARs) In certain embodiments, the antigen-recognizing receptor is a CAR. A CAR is an engineered receptor that grafts or confers a desired specificity onto an immune effector cell or immune responsive cell. CARs can be used to confer non-MHC-restricted antigen specificity to T cells. The transfer of their coding sequences is facilitated by retroviral vectors.
[0147] CARs have been developed through a series of significant improvements called "generations." So-called "first-generation" CARs typically consist of an extracellular antigen-binding domain (e.g., a single-chain variable fragment (scFv)) fused to a transmembrane domain fused to a cytoplasmic / intracellular signaling domain. The cytoplasmic / intracellular signaling domain may contain a single activation domain (usually an ITAM derived from CD3 zeta). "First-generation" CARs provide de novo antigen recognition independent of HLA-mediated antigen presentation and bind to CD4 ζ chains through their CD3ζ chain signaling domain in a single fusion molecule.+ T cells and CD8 + The antigen-recognizing receptor can induce both activation and activation of T cells. "Second-generation" CARs add an intracellular signaling domain derived from any one of a variety of costimulatory molecules (e.g., CD28, 4-1BB, ICOS, OX40) to the cytoplasmic tail of the CAR to provide an additional signal to the T cell. "Second-generation" CARs include those that provide both costimulation (e.g., CD28 or 4-1BB) and activation (CD3ζ). "Third-generation" CARs include those that provide multiple costimulation (e.g., CD28 and 4-1BB) and activation (CD3ζ). In certain embodiments, the antigen-recognizing receptor is a first-generation CAR. In certain embodiments, the antigen-recognizing receptor is a second-generation CAR. In certain embodiments, the antigen-recognizing receptor is a third-generation CAR.
[0148] In certain embodiments, the extracellular antigen binding domain of the CAR (e.g., embodied in an scFv or analog thereof) is about 2 x 10 -7 The dissociation constant (K d ) binds to the antigen. In certain embodiments, K d is about 2 x 10 -7 M or less, approximately 1×10 -7 M or less, approximately 9 x 10 -8 M or less, approximately 1×10 -8 M or less, approximately 9 x 10 -9 M or less, about 5 x 10 -9 M or less, approximately 4 x 10 -9 M or less, about 3 x 10 -9 Below, approximately 2×10 -9 M or less, or about 1 x 10 -9 In certain embodiments, K d is about 3 x 10 -9 In certain embodiments, K d is approximately 1 x 10 -9 M to approx. 3 x 10 -7 M. In certain embodiments, K d is approximately 1.5 x 10 -9 M to approx. 3 x 10 -7 M. In certain embodiments, K d is approximately 1.5 x 10 -9 M to approximately 2.7 x 10-7 It's M.
[0149] Binding of the extracellular antigen-binding domain (e.g., scFv or analog thereof) can be confirmed, for example, by enzyme-linked immunosorbent assay (ELISA), radioimmunoassay (RIA), FACS analysis, bioassay (e.g., growth inhibition), or Western blot assay. Each of these assays generally detects the presence of a protein-antibody complex of particular interest by using a labeled reagent (e.g., antibody or scFv) specific for the complex of interest. For example, scFv can be radioactively labeled and used in a radioimmunoassay (RIA) (see, e.g., Weintraub, B., Principles of Radioimmunoassays, Seventh Training Course on Radioligand Assay Techniques, The Endocrine Society, March, 1986, incorporated herein by reference). Radioisotopes can be detected by means such as the use of a gamma counter or scintillation counter, or by autoradiography. In certain embodiments, the extracellular antigen-binding domain of the CAR is labeled with a fluorescent marker. Non-limiting examples of fluorescent markers include green fluorescent protein (GFP), blue fluorescent protein (e.g., EBFP, EBFP2, Azurite, and mKalama1), cyan fluorescent protein (e.g., ECFP, Cerulean, and CyPet), and yellow fluorescent protein (e.g., YFP, Citrine, Venus, and YPet). Binding of the extracellular antigen-binding domain can also be confirmed by measuring cytokine secretion.
[0150] In accordance with the presently disclosed subject matter, a CAR comprises an extracellular antigen-binding domain, a transmembrane domain, and an intracellular signaling domain, wherein the extracellular antigen-binding domain specifically binds to an antigen, which may be a tumor antigen (TAA or TSA) or a pathogen antigen.
[0151] In certain embodiments, the CAR comprises an extracellular antigen-binding domain that binds to CD 19. In certain embodiments, the CAR is one described in Kochenderder, JN et al. Blood. 2010 Nov 11;116(19):3875-86, which is incorporated herein by reference in its entirety.

[0199] 4.Cells The presently disclosed subject matter provides cells comprising a dominant-negative Fas polypeptide disclosed herein. In certain embodiments, the cells further comprise an antigen-recognition receptor (e.g., a CAR or TCR) that binds to an antigen. In certain embodiments, the dominant-negative Fas polypeptide is an exogenous dominant-negative Fas polypeptide. In certain embodiments, the antigen-recognition receptor is capable of activating the cell. In certain embodiments, the dominant-negative Fas polypeptide (e.g., an exogenous dominant-negative Fas polypeptide) can promote the anti-tumor effect of the cell. The cell can be transduced with an antigen-recognition receptor and an exogenous dominant-negative Fas polypeptide such that the cell co-expresses the antigen-recognition receptor and the exogenous dominant-negative Fas polypeptide.
[0200] In certain embodiments, the cell is an immunoresponsive cell. In certain embodiments, the cell is a cell of the lymphoid lineage. Cells of the lymphoid lineage produce antibodies, regulate the cellular immune system, detect foreign pathogens in the blood and cells foreign to the host, etc. Non-limiting examples of cells of the lymphoid lineage include T cells, natural killer (NK) cells, B cells, dendritic cells, and stem cells from which lymphoid cells can be differentiated. In certain embodiments, the stem cell is a pluripotent stem cell (e.g., an embryonic stem cell or an induced pluripotent stem cell).
[0201] In certain embodiments, the cell is a T cell. T cells can be lymphocytes that mature in the thymus and are primarily responsible for cell-mediated immunity. T cells are members of the adaptive immune system. In certain embodiments, T cells provided herein include, but are not limited to, helper T cells, cytotoxic T cells, memory T cells (central memory T cells, stem cell-like memory T cells (or stem-like memory T cells)), and two types of effector memory T cells: e.g., T EM Cells and T EMRA cells, regulatory T cells (suppressor T cells or T regsThe present invention relates to T cells, including any type of T cell, including T cells (also known as T cells), tumor-infiltrating lymphocytes (TILs), natural killer T cells, mucosal-associated invariant T cells, and γδ T cells. Cytotoxic T cells (CTLs or killer T cells) are a subset of T lymphocytes that can induce the death of infected somatic or tumor cells. A patient's own T cells (i.e., autologous T cells) can be genetically modified to target specific antigens by the introduction of an antigen-recognition receptor, e.g., a CAR or TCR. In certain embodiments, the cells are T cells. T cells are CD4 + T cells or CD8 + In certain embodiments, the T cells are CD4 + In certain embodiments, the T cells are CD8 + T cells.
[0202] In certain embodiments, the cell is a virus-specific T cell. In certain embodiments, the virus-specific T cell comprises an endogenous TCR that recognizes a viral antigen. In certain embodiments, the cell is a tumor-specific T cell. In certain embodiments, the tumor-specific T cell comprises an endogenous TCR that recognizes a tumor antigen (TSA or TAA).
[0203] In certain embodiments, the cells are NK cells. Natural killer (NK) cells are lymphocytes that are part of cell-mediated immunity and act during the innate immune response. NK cells do not require prior activation to carry out their cytotoxic effect on target cells.
[0204] The types of human lymphocytes of the presently disclosed subject matter include, but are not limited to, peripheral donor lymphocytes, e.g., Sadelain, M. et al. 2003 Nat Rev Cancer 3:35-45 (disclosing peripheral donor lymphocytes genetically modified to express CARs), Morgan, RA et al. 2006 Science 314:126-129 (disclosing peripheral donor lymphocytes genetically modified to express T cell receptor complexes that recognize full-length tumor antigens, including α and β heterodimers), Panelli, MC et al. 2000 J Immunol 164:495-504; Panelli, MC et al. 2000 J Immunol 164:4382-4392 (disclosing lymphocyte cultures derived from tumor-infiltrating lymphocytes (TILs) in tumor biopsies), and Dupont, J. et al. 2005 Cancer Res 65:5417-5427; Papanicolaou, GA et al. 2003 Blood 102:2498-2505 (disclosing selectively antigen-specific peripheral blood leukocytes expanded in vitro using artificial antigen presenting cells (AAPCs) or pulsed dendritic cells). Immunoresponsive cells (e.g., T cells) can be autologous, non-autologous (e.g., allogeneic), or derived in vitro from modified progenitor or stem cells.
[0205] In certain embodiments, the cells are cells of the myeloid lineage. Non-limiting examples of cells of the myeloid lineage include monocytes, macrophages, basophils, neutrophils, eosinophils, mast cells, erythrocytes, megakaryocytes, platelets, and stem cells from which myeloid cells can be differentiated. In certain embodiments, the stem cells are pluripotent stem cells (e.g., embryonic stem cells or induced pluripotent stem cells).
[0206] The cells of the present disclosure can modulate the tumor microenvironment. Tumors have a microenvironment that is hostile to the host immune response, including a series of mechanisms by malignant cells to protect themselves from immune recognition and elimination. This hostile "tumor microenvironment" includes infiltrating regulatory CD4 +The tumor microenvironment contains a variety of immunosuppressive factors, including T cells (Tregs), myeloid-derived suppressor cells (MDSCs), tumor-associated macrophages (TAMs), immunosuppressive cytokines including TGF-β, and expression of ligands that target immunoinhibitory receptors (CTLA-4 and PD-1) expressed by activated T cells. These mechanisms of immunosuppression play a role in maintaining tolerance and suppressing inappropriate immune responses, but within the tumor microenvironment, these mechanisms prevent effective antitumor immune responses. Collectively, these immunosuppressive factors can induce either significant anergy or apoptosis of adoptively transferred CAR-modified T cells upon encounter with targeted tumor cells.
[0207] In certain embodiments, the cells of the present disclosure have increased cell persistence, hi certain embodiments, the cells of the present disclosure have reduced apoptosis and / or anergy.
[0208] 5. Compositions and Vectors The presently disclosed subject matter provides compositions comprising a dominant-negative Fas polypeptide disclosed herein (e.g., as disclosed in Section 2) and an antigen-recognizing receptor disclosed herein (e.g., as disclosed in Section 3). Also provided are cells (e.g., immunoresponsive cells) comprising such compositions.
[0209] In certain embodiments, the dominant negative Fas polypeptide is operably linked to a first promoter. In certain embodiments, the antigen recognizing receptor is operably linked to a second promoter.
[0210] Additionally, the presently disclosed subject matter provides nucleic acid compositions comprising a first polynucleotide encoding a dominant-negative Fas polypeptide disclosed herein (e.g., as disclosed in Section 2) and a second polynucleotide encoding an antigen-recognizing receptor disclosed herein (e.g., as disclosed in Section 3). Also provided are cells comprising such nucleic acid compositions.
[0211] In certain embodiments, the nucleic acid composition further comprises a first promoter operably linked to the dominant-negative Fas polypeptide, hi certain embodiments, the nucleic acid composition further comprises a second promoter operably linked to an antigen-recognizing receptor.
[0212] In certain embodiments, one or both of the first and second promoters are endogenous or exogenous. In certain embodiments, the exogenous promoter is selected from the group consisting of an elongation factor (EF)-1 promoter, a CMV promoter, an SV40 promoter, a PGK promoter, a long terminal repeat (LTR) promoter, and a metallothionein promoter. In certain embodiments, one or both of the first and second promoters is an inducible promoter. In certain embodiments, the inducible promoter is selected from the group consisting of an NFAT transcription response element (TRE) promoter, a CD69 promoter, a CD25 promoter, an IL-2 promoter, an IL-12 promoter, a p40 promoter, and a Bcl-xL promoter.
[0213] The presently disclosed subject matter further provides a vector comprising the nucleic acid composition. In certain embodiments, the vector is a retroviral vector. In certain embodiments, the vector is a lentiviral vector.
[0214] Compositions and nucleic acid compositions can be administered to a subject and / or delivered to cells by methods known in the art or as described herein. Genetic modification of cells (e.g., T cells) can be achieved by transducing a substantially homogeneous cell composition with a recombinant DNA construct. In certain embodiments, retroviral vectors (either gammaretroviral or lentiviral vectors) are used to introduce DNA constructs into cells. For example, a first polynucleotide encoding an antigen-recognizing receptor and a second polynucleotide encoding a dominant-negative Fas polypeptide can be cloned into a retroviral vector, and expression can be driven from its endogenous promoter, from a retroviral terminal repeat, or from a promoter specific to the target cell type of interest. Non-viral vectors can also be used.
[0215] For the initial genetic modification of cells to include a dominant-negative Fas polypeptide and an antigen-recognizing receptor (e.g., a CAR or TCR), retroviral vectors are commonly used for transduction, although any other suitable viral vector or non-viral delivery system can be used. The antigen-recognizing receptor and dominant-negative Fas polypeptide can be constructed in a single polycistronic expression cassette, multiple expression cassettes in a single vector, or multiple vectors. Examples of elements that can be used to create polycistronic expression cassettes include, but are not limited to, various viral and non-viral internal ribosome entry sites (IRES, e.g., FGF-1 IRES, FGF-2 IRES, VEGF IRES, IGF-II IRES, NF-κB IRES, RUNX1 IRES, p53 IRES, Hepatitis A IRES, Hepatitis C IRES, Pestivirus IRES, Aphthovirus IRES, Picornavirus IRES, Poliovirus IRES, and Encephalomyocarditis virus IRES), and cleavable linkers (e.g., 2A peptides, e.g., P2A, T2A, E2A, and F2A peptides). Also suitable are combinations of retroviral vectors and appropriate packaging lines, wherein the capsid protein is functional to infect human cells. A variety of amphotropic virus-producing cell lines are known, including, but not limited to, PA12 (Miller et al. (1985) Mol. Cell. Biol. 5:431-437); PA317 (Miller et al. (1986) Mol. Cell. Biol. 6:2895-2902); and CRIP (Danos et al. (1988) Proc. Natl. Acad. Sci. USA 85:6460-6464). Non-amphotropic particles, such as those pseudotyped with VSVG, RD114, or GALV envelopes, and any others known in the art, are also suitable.
[0216] Possible methods of transduction also include direct co-cultivation of cells with producer cells, e.g., by the method of Bregni et al. (1992) Blood 80:1418-1422, or by culturing with viral supernatant alone or with concentrated vector stock with or without appropriate growth factors and polycations, e.g., by the method of Xu et al. (1994) Exp. Hemat. 22:223-230; and Hughes et al. (1992) J. Clin. Invest. 89:1817.
[0217] Other transducing viral vectors can be used to modify cells. In certain embodiments, the vector selected exhibits high efficiency of infection and stable integration and expression (see, e.g., Cayouette et al., Human Gene Therapy 8:423-430, 1997; Kido et al., Current Eye Research 15:833-844, 1996; Bloomer et al., Journal of Virology 71:6641-6649, 1997; Naldini et al., Science 272:263-267, 1996; and Miyoshi et al., Proc. Natl. Acad. Sci. USA 94:10319, 1997). Other viral vectors that can be used include, for example, adenovirus, lentivirus, and adeno-associated virus vectors, vaccinia virus, bovine papilloma virus, or herpes viruses such as Epstein-Barr virus (see, e.g., Miller, Human Gene Therapy 15-14, 1990; Friedman, Science 244:1275-1281, 1989; Eglitis et al., BioTechniques 6:608-614, 1988; Tolstoshev et al., Current Opinion in Biotechnology 1:55-61, 1990; Sharp, The Lancet 337:1277-1278, 1991; Cornetta et al., Nucleic Acid Research and Molecular Biology 36:311-322, 1987; Anderson, Science 226:401-409, 1984; Moen, Blood Cells 17:407-416, 1991; Miller et al., Biotechnology 7:980-990, 1989; LeGal La Salle et al., Science 259:988-990, 1993; and Johnson, Chest 107:77S-83S, 1995.) Retroviral vectors are particularly well developed and have been used in clinical settings (Rosenberg et al., N. Engl. J. Med 323:370, 1990; Anderson et al., U.S. Pat. No. 5,399,346).
[0218] Non-viral approaches can also be used to genetically modify cells. For example, nucleic acid molecules can be introduced into cells by administering nucleic acids in the presence of lipofection (Feigner et al., Proc. Natl. Acad. Sci. USA 84:7413, 1987; Ono et al., Neuroscience Letters 17:259, 1990; Brigham et al., Am. J. Med. Sci. 298:278, 1989; Staubinger et al., Methods in Enzymology 101:512, 1983), asialoorosomucoid-polylysine conjugation (Wu et al., Journal of Biological Chemistry 263:14621, 1988; Wu et al., Journal of Biological Chemistry 264:16985, 1989), or by microinjection under surgical conditions (Wolff et al., Science 247:1465, 1990) into immunocompetent cells. Other non-viral means for gene transfer include in vitro transfection using calcium phosphate, DEAE-dextran, electroporation, and protoplast fusion. Liposomes can also be potentially useful for delivering DNA to cells. Transplantation of normal genes into affected tissues of a subject can also be achieved by introducing normal nucleic acids into ex vivo culturable cell types (e.g., autologous or heterologous primary cells or their progeny), and then the cells (or their progeny) are injected into the targeted tissue or systemically. Recombinant receptors can also be induced or obtained using transposases or targeted nucleases (e.g., zinc finger nucleases, meganucleases, or TALE nucleases, CRISPR). Transient expression may be achieved by RNA electroporation.
[0219] Any targeted genome editing method can also be used to deliver the dominant-negative Fas polypeptides and / or antigen-recognition receptors disclosed herein to cells or subjects. In certain embodiments, a CRISPR system is used to deliver the dominant-negative Fas polypeptides and / or antigen-recognition receptors disclosed herein. In certain embodiments, a zinc finger nuclease is used to deliver the dominant-negative Fas polypeptides and / or antigen-recognition receptors disclosed herein. In certain embodiments, a TALEN system is used to deliver the dominant-negative Fas polypeptides and / or antigen-recognition receptors disclosed herein.
[0220] The clustered regularly interspaced short palindromic repeats (CRISPR) system is a genome editing tool discovered in prokaryotic cells. When utilized for genome editing, this system comprises Cas9 (a protein that can modify DNA using crRNA as its guide), CRISPR RNA (crRNA, which contains the RNA used by Cas9 to guide it to the correct part of the host DNA along with a region that binds to tracrRNA (generally in the form of a hairpin loop) that forms an active complex with Cas9), transactivating crRNA (tracrRNA, which binds to crRNA and forms an active complex with Cas9), and an optional portion of DNA repair template (DNA that guides the cellular repair process, allowing for the insertion of a specific DNA sequence). CRISPR / Cas9 often uses a plasmid to transfect target cells. The crRNA is the sequence that Cas9 uses to identify and directly bind to the target DNA in the cell, and therefore must be designed for each application. The repair template carrying the CAR expression cassette must also be designed for each application, as it must overlap with the sequences on either side of the cut and encode the insertion sequence. Multiple crRNAs and tracrRNAs can be packaged together to form single guide RNAs (sgRNAs), which can be joined with the Cas9 gene into a plasmid for transfection into cells.
[0221] Zinc finger nucleases (ZFNs) are artificial restriction enzymes created by combining a zinc finger DNA-binding domain with a DNA cleavage domain. The zinc finger domain can be engineered to target specific DNA sequences, allowing the zinc finger nuclease to target desired sequences within the genome. The DNA-binding domain of an individual ZFN typically contains multiple individual zinc finger repeats, each capable of recognizing multiple base pairs. The most common method for creating new zinc finger domains is to combine smaller zinc finger "modules" of known specificity. The most common cleavage domain in ZFNs is the nonspecific cleavage domain derived from the type II restriction endonuclease FokI. Using the endogenous homologous recombination (HR) machinery and a homologous DNA template bearing the CAR expression cassette, ZFNs can be used to insert a CAR expression cassette into a genome. When the targeting sequence is cleaved by the ZFN, the HR machinery searches for homology between the damaged chromosome and the homologous DNA template and then copies the sequence of the template between the two cut ends of the chromosome, thereby integrating the homologous DNA template into the genome.
[0222] Transcription activator-like effector nucleases (TALENs) are restriction enzymes that can be engineered to cleave specific sequences in DNA. TALEN systems operate on much the same principle as ZFNs. They are created by combining a transcription activator-like effector DNA-binding domain with a DNA-cleavage domain. Transcription activator-like effectors (TALEs) contain a repeating motif of 33-34 amino acids with two variable positions that have strong recognition for specific nucleotides. By assembling an array of these TALEs, the TALE DNA-binding domain can be engineered to bind to a desired DNA sequence, thereby directing the nuclease to cleave at specific locations in the genomic DNA sequence.
[0223] Polynucleotide therapeutics can be directed from any suitable promoter (e.g., human cytomegalovirus (CMV), simian virus 40 (SV40), or metallothionein promoter) and can be regulated by any suitable mammalian regulatory element or intron (e.g., elongation factor 1a enhancer / promoter / intron structure). For example, if desired, enhancers known to preferentially direct gene expression in particular cell types can be used to direct expression of the nucleic acid. Enhancers used can include, but are not limited to, those characterized as tissue- or cell-specific enhancers. Alternatively, if a genomic clone is used as a therapeutic construct, regulation can be mediated by cognate regulatory sequences or, if desired, by regulatory sequences derived from heterologous sources, including any of the promoters or regulatory elements described above.
[0224] The method for delivering the genome editing agent / system can vary depending on the need. In certain embodiments, the components of the selected genome editing method are delivered as a DNA construct in one or more plasmids. In certain embodiments, the components are delivered via a viral vector. Common delivery methods include, but are not limited to, electroporation, microinjection, gene gun, impale infection, hydrostatic pressure, continuous infusion, sonication, magnetofection, adeno-associated virus, envelope protein pseudotyping of viral vectors, cis- and trans-acting elements of replication-competent vectors, herpes simplex virus, and chemical vehicles (e.g., oligonucleotides, lipoplexes, polymersomes, polyplexes, dendrimers, inorganic nanoparticles, and cell-penetrating peptides).
[0225] The resulting cells can be grown under conditions similar to those for the unmodified cells, allowing the modified cells to be grown and used for a variety of purposes.
[0226] 6. Polypeptides and Analogs Also included within the presently disclosed subject matter are CD19, CD28, 4-1BB, CD8, CD3ζ, and Fas polypeptides or fragments thereof that are modified in a manner that enhances their antineoplastic activity when expressed in immunoresponsive cells. The presently disclosed subject matter provides methods for optimizing amino acid or nucleic acid sequences by making modifications in the sequence. Such modifications can include certain mutations, deletions, insertions, or post-translational modifications. The presently disclosed subject matter further includes analogs of any naturally occurring polypeptides disclosed herein (including, but not limited to, CD19, CD8, 4-1BB, CD28, CD3ζ, and Fas). Analogs can differ from the naturally occurring polypeptides disclosed herein by differences in amino acid sequence, by post-translational modifications, or both. Analogs may exhibit at least about 85%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, about 99% or more homology or identity to all or a portion of a naturally occurring amino acid sequence of the presently disclosed subject matter. The length of sequence comparison may be at least 5, 10, 15, or 20 amino acid residues, e.g., at least 25, 50, or 75 amino acid residues, or more than 100 amino acid residues. Also, in an exemplary approach to determining the degree of identity, a BLAST program may be used to compare closely related sequences. -3 and e -100A probability score between 0 and 1 may be used. Modifications include in vivo and in vitro chemical derivatization of polypeptides, such as acetylation, carboxylation, phosphorylation, or glycosylation; such modifications can occur during polypeptide synthesis or processing, or after treatment with isolated modifying enzymes. Analogs can also differ from naturally occurring polypeptides by alterations in primary sequence. These include genetic variants, both natural and induced (resulting from random or site-specific mutagenesis, e.g., by exposure to irradiation or ethane methyl sulfate, as described in Sambrook, Fritsch, and Maniatis, Molecular Cloning: A Laboratory Manual (2nd ed.), CSH Press, 1989, or Ausubel et al., supra). Also included are cyclized peptides, molecules, and analogs that include residues other than L-amino acids, e.g., D-amino acids, or non-naturally occurring or synthetic amino acids, e.g., β- or γ-amino acids.
[0227] In addition to full-length polypeptides, the presently disclosed subject matter also provides fragments of any of the polypeptide or peptide domains disclosed herein. As used herein, the term "fragment" means at least 5, 10, 13, or 15 amino acids. In certain embodiments, fragments comprise at least 20 contiguous amino acids, at least 30 contiguous amino acids, or at least 50 contiguous amino acids. In certain embodiments, fragments comprise at least 60 to 80, 100, 200, 300, or more contiguous amino acids. Fragments can be generated by methods known to those of skill in the art or can be derived from normal protein processing (e.g., removal of amino acids from a nascent polypeptide that are not required for biological activity, or removal of amino acids by alternative mRNA splicing or alternative protein processing events).
[0228] Non-protein analogs have chemical structures designed to mimic the functional activity of the proteins disclosed herein (e.g., dominant-negative Fas polypeptides). Such analogs may exceed the physiological activity of the original polypeptide. Methods for analog design are well known in the art, and analog synthesis can be carried out according to such methods by modifying the chemical structure so that the resulting analog increases the antineoplastic activity of the original polypeptide when expressed in immunoresponsive cells. These chemical modifications include, but are not limited to, substituting alternative R groups and changing the degree of saturation of particular carbon atoms of the reference polypeptide. In certain embodiments, protein analogs are relatively resistant to in vivo degradation and produce a longer-lasting therapeutic effect upon administration. Assays for measuring functional activity include, but are not limited to, those described in the Examples below.
[0229] 7. Administration The cells of the present disclosure or compositions comprising same can be provided systemically or directly to a subject to induce and / or enhance an immune response to an antigen and / or to treat and / or prevent a neoplasm and / or pathogen infection. In certain embodiments, the cells of the present disclosure or compositions comprising same are directly injected into an organ of interest (e.g., an organ affected by a neoplasm). Alternatively, the cells of the present disclosure or compositions comprising same are provided indirectly to an organ of interest, for example, by administration into the circulatory system (e.g., tumor vasculature). Growth and differentiation agents can be provided before, during, or after administration of the cells or compositions to increase the in vitro or in vivo production of T cells or NK cells.
[0230] The cells of the present disclosure can be administered in any physiologically acceptable vehicle, usually intravascularly, although the cells may also be introduced into bone or other convenient sites (e.g., the thymus) where the cells may find a suitable site for regeneration and differentiation. Typically, at least about 1 x 10 5 cells were administered, resulting in a final total of approximately 1 × 10 10The cells of the present disclosure may comprise a population of purified cells. One skilled in the art can easily determine the percentage of cells of the present disclosure in a population using various well-known methods, such as fluorescence-activated cell sorting (FACS). Suitable ranges of purity in a population containing cells of the present disclosure are about 50% to about 55%, about 5% to about 60%, and about 65% to about 70%. In certain embodiments, the purity is about 70% to about 75%, about 75% to about 80%, or about 80% to about 85%. In certain embodiments, the purity is about 85% to about 90%, about 90% to about 95%, and about 95% to about 100%. Dosage can be easily adjusted by one skilled in the art (e.g., a decrease in purity may require an increase in dosage). Cells can be introduced by injection, catheter, etc.
[0231] The compositions of the present disclosure can be pharmaceutical compositions comprising the cells of the present disclosure or their progenitor cells and a pharmaceutically acceptable carrier. Administration can be autologous or heterologous. For example, cells or progenitor cells can be obtained from one subject and administered to the same subject or to a different compatible subject. Peripheral blood-derived cells or their progeny (e.g., derived in vivo, ex vivo, or in vitro) can be administered via catheter administration, systemic injection, local injection, intravenous injection, or local injection, including parenteral administration. When administering a therapeutic composition of the present disclosure, it can be formulated into a unit-dosage injectable form (solution, suspension, emulsion).
[0232] 8. Preparation Compositions containing the cells of the present disclosure can be conveniently provided as sterile liquid preparations, such as isotonic aqueous solutions, suspensions, emulsions, dispersions, or viscous compositions, which may be buffered to a selected pH. Liquid preparations are generally easier to prepare than gels, other viscous compositions, and solid compositions. In addition, liquid compositions are somewhat more convenient to administer, particularly by injection. On the other hand, viscous compositions can be formulated within an appropriate viscosity range to provide longer contact periods with specific tissues. Liquid or viscous compositions can contain a carrier, which can be a solvent or dispersion medium, including, for example, water, saline, phosphate-buffered saline, polyols (e.g., glycerol, propylene glycol, liquid polyethylene glycol, etc.), and suitable mixtures thereof.
[0233] Sterile injectable solutions can be prepared by incorporating the genetically modified immunoresponsive cells in the required amount of an appropriate solvent with various amounts of other ingredients, as desired. Such compositions may be in admixture with a suitable carrier, diluent, or additive, such as sterile water, physiological saline, glucose, dextrose, or the like. The compositions can also be lyophilized. The compositions may contain auxiliary substances, such as wetting agents, dispersing or emulsifying agents (e.g., methylcellulose), pH buffering agents, gelling or thickening additives, preservatives, flavoring agents, coloring agents, and the like, depending on the desired route of administration and preparation. Suitable preparations may be prepared without undue experimentation with reference to standard texts, such as "REMINGTON'S PHARMACEUTICAL SCIENCE," 17th Edition, 1985, incorporated herein by reference.
[0234] Various additives can be added to enhance the stability and sterility of the compositions, including antimicrobial preservatives, antioxidants, chelating agents, and buffers. Prevention of microbial activity can be ensured by various antibacterial and antifungal agents, such as parabens, chlorobutanol, phenol, sorbic acid, and the like. Prolonged absorption of injectable pharmaceutical forms can be brought about by the use of agents delaying absorption, such as aluminum monostearate and gelatin. However, according to the subject matter of the present disclosure, any vehicle, diluent, or additive used must be compatible with the genetically modified immunoresponsive cells or their precursor cells.
[0235] The compositions may be isotonic, i.e., they may have the same osmotic pressure as blood and tears. The desired isotonicity of the composition may be achieved using sodium chloride or other pharmaceutically acceptable agents such as dextrose, boric acid, sodium tartrate, propylene glycol, or other inorganic or organic solutes. Sodium chloride may be used, particularly for buffers containing sodium ions.
[0236] The viscosity of the composition can be maintained at a selected level, if desired, using a pharmaceutically acceptable thickening agent. For example, methylcellulose is readily and economically available and easy to work with. Other suitable thickening agents include, for example, xanthan gum, carboxymethylcellulose, hydroxypropylcellulose, carbomer, and the like. The concentration of the thickening agent can depend on the drug selected. The key is to use an amount that achieves the selected viscosity. Obviously, the selection of appropriate carriers and other additives will depend on the exact route of administration and the nature of the particular dosage form, e.g., liquid dosage form (e.g., whether the composition is formulated as a solution, suspension, gel, or another liquid form, e.g., sustained-release form or liquid-filled form).
[0237] The amount of cells administered will vary depending on the subject being treated. In one embodiment, about 10 4 from about 10 10 Between about 10 5 from about 10 9Between, or about 10 6 from about 10 8 Between about 1 x 10 cells of the present disclosure are administered to a human subject. More effective cells may be administered in even smaller numbers. In certain embodiments, at least about 1 x 10 cells are administered. 8 pieces, approximately 2×10 8 pieces, about 3 x 10 8 pieces, about 4×10 8 or approximately 5 x 10 8 The cells of the present disclosure are administered to a human subject. The precise determination of what is considered an effective dose can be based on individual factors for each subject, including the size, age, sex, weight, and condition of the particular subject. Dosages can be readily ascertained by one skilled in the art from this disclosure and knowledge in the art.
[0238] Those skilled in the art can easily determine the amount of cells and optional additives, vehicles, and / or carriers in the compositions and administered in the methods. Typically, any additives (in addition to active cells and / or drugs) are present in an amount of 0.001 to 50% (by weight) solution in phosphate-buffered saline, and the active ingredient is present in amounts on the order of micrograms to milligrams, e.g., about 0.0001 to about 5% by weight, about 0.0001 to about 1% by weight, about 0.0001 to about 0.05% by weight, or about 0.001 to about 20% by weight, about 0.01 to about 10% by weight, or about 0.05 to about 5% by weight. For any composition administered to animals or humans, the following can be determined: toxicity, such as by determining the lethal dose (LD) and LD50 in an appropriate animal model, e.g., rodents such as mice; the dosage of the composition, the concentration of components therein, and the timing of administering the composition that will elicit an appropriate response. Such determinations do not require undue experimentation from the knowledge of one of ordinary skill in the art, this disclosure, and the documents cited herein, and the time for sequential administration can be ascertained without undue experimentation.
[0239] 9.Treatment method The presently disclosed subject matter provides methods for inducing and / or increasing an immune response in a subject in need thereof. The cells of the present disclosure and compositions comprising them can be used to treat and / or prevent a neoplasm in a subject. The cells of the present disclosure and compositions comprising them can be used to prolong the survival of a subject suffering from a neoplasm. The cells of the present disclosure and compositions comprising them can also be used to treat and / or prevent a neoplasm in a subject. The cells of the present disclosure and compositions comprising them can also be used to reduce tumor burden in a subject. The cells of the present disclosure and compositions comprising them can also be used to treat and / or prevent pathogen infection or other infectious disease in a subject, e.g., an immunocompromised human subject. Such methods include administering the cells of the present disclosure or a composition comprising them (e.g., a pharmaceutical composition) in an amount effective to achieve the desired effect, which is the alleviation of an existing condition or the prevention of recurrence. For treatment, the amount administered is an amount effective to produce the desired effect. An effective amount can be provided in a single or series of administrations. An effective amount can be provided by bolus or continuous perfusion.
[0240] In adoptive immunotherapy using antigen-specific T cells, typically about 10 6 -10 11 pieces (e.g., about 10 9 A cell dose in the range of 1000 to 10000 cells is injected. Upon administration of the cells of the present disclosure to a host and subsequent differentiation, T cells specifically directed against a specific antigen are induced. The modified cells can be administered by any method known in the art, including, but not limited to, intravenous, subcutaneous, intranodal, intratumoral, intrathecal, intrapleural, intraperitoneal, intramedullary, and directly into the thymus.
[0241] The presently disclosed subject matter provides methods for treating and / or preventing a neoplasm in a subject. In certain embodiments, the methods comprise administering to a subject having a neoplasm an effective amount of a cell of the present disclosure or a composition comprising the same.
[0242] In certain embodiments, the neoplasm is a malignant neoplasm. In certain embodiments, the neoplasm or tumor is a cancer with increased FASLG RNA expression relative to matched normal tissue of origin. See Yamamoto et al., J Clin Invest. (2019); 129(4):1551-1565, incorporated herein by reference.
[0243] Non-limiting examples of neoplasms (e.g., malignant neoplasms) include blood cancers (e.g., leukemia, lymphoma, and myeloma), ovarian cancer, breast cancer, bladder cancer, brain cancer, colon cancer, intestinal cancer, liver cancer, lung cancer, pancreatic cancer, prostate cancer, skin cancer, gastric cancer, glioblastoma, pharyngeal cancer, melanoma, neuroblastoma, adenocarcinoma, glioma, soft tissue sarcoma, and various carcinomas (including prostate cancer and small cell lung cancer). Suitable carcinomas include, but are not limited to, astrocytoma, fibrosarcoma, myxosarcoma, liposarcoma, oligodendroglioma, ependymoma, medulloblastoma, primitive neuroectodermal tumor (PNET), chondrosarcoma, osteogenic sarcoma, pancreatic ductal adenocarcinoma, small cell and large cell lung adenocarcinoma, chordoma, angiosarcoma, endothelial sarcoma, squamous cell carcinoma, bronchoalveolar carcinoma, epithelial adenocarcinoma and its liver metastases, lymphangiosarcoma, lymphangioendothelial sarcoma, hepatocellular carcinoma, cholangiocellular carcinoma, synovioma, mesothelioma, Ewing's tumor, rhabdomyosarcoma, colon carcinoma, basal cell carcinoma, sweat gland carcinoma, papillary carcinoma, sebaceous gland carcinoma, papillary adenocarcinoma, cystadenocarcinoma, medullary carcinoma, bronchogenic carcinoma, renal cell carcinoma, cholangiocarcinoma, choriocarcinoma, seminoma, embryonal carcinoma, Further included are any known in the field of oncology, including Wilms' tumor, testicular tumor, medulloblastoma, craniopharyngioma, ependymoma, pinealoma, hemangioblastoma, acoustic neuroma, oligodendroglioma, meningioma, neuroblastoma, retinoblastoma, leukemia, multiple myeloma, Waldenstrom's macroglobulinemia, and heavy chain disease, breast tumors such as ductal and lobular adenocarcinoma, squamous cell and adenocarcinoma of the cervix, epithelial carcinoma of the uterus and ovary, prostate adenocarcinoma, transitional squamous cell carcinoma of the bladder, B and T cell lymphoma (nodular and scattered), plasmacytoma, acute and chronic leukemia, malignant melanoma, soft tissue sarcoma, and leiomyosarcoma. In certain embodiments, the neoplasm (e.g., malignant neoplasm) is selected from the group consisting of hematological cancer (e.g., leukemia, lymphoma, and myeloma), ovarian cancer, prostate cancer, breast cancer, bladder cancer, brain cancer, colon cancer, intestinal cancer, liver cancer, lung cancer, pancreatic cancer, prostate cancer, skin cancer, gastric cancer, glioblastoma, and pharyngeal cancer. In certain embodiments, the immunoresponsive cells of the present disclosure and compositions comprising same can be used to treat and / or prevent hematological cancer (e.g., leukemia, lymphoma, and myeloma) or ovarian cancer that are refractory to typical therapeutic interventions.
[0244] In certain embodiments, the neoplasm is a solid cancer or solid tumor, hi certain embodiments, the solid tumor or solid cancer is selected from the group consisting of glioblastoma, prostate adenocarcinoma, papillary cell renal carcinoma, sarcoma, ovarian cancer, pancreatic adenocarcinoma, rectal adenocarcinoma, colon adenocarcinoma, esophageal cancer, uterine endometrioid carcinoma, breast cancer, cutaneous melanoma, lung adenocarcinoma, gastric adenocarcinoma, cervical cancer, renal clear cell carcinoma, testicular germ cell tumor, and aggressive B-cell lymphoma.
[0245] The subject may have an advanced form of the disease, in which case the treatment objectives may include slowing or reversing disease progression and / or ameliorating side effects. The subject may have a history of a condition that has already been treated, in which case the treatment objectives typically include reducing or delaying the risk of recurrence.
[0246] Human subjects suitable for treatment typically comprise two treatment groups that can be distinguished by clinical criteria. Subjects with "advanced disease" or "high tumor burden" are those with clinically measurable tumors. Clinically measurable tumors are those that can be detected based on tumor burden (e.g., by palpation, CAT scan, sonogram, mammogram, or X-ray; positive biochemical or histopathological markers alone are insufficient to identify this population). Pharmaceutical compositions are administered to these subjects to elicit an anti-tumor response with the goal of alleviating the subject's condition. Ideally, a reduction in tumor burden occurs as a result, although any clinical improvement constitutes benefit. Clinical improvement includes a reduction in the risk or rate of tumor progression or a reduction in the pathological consequences of the tumor.
[0247] A second group of suitable subjects is known in the art as the "adjuvant group." These are individuals who have a history of neoplasia but have responded to other treatment modalities. Previous treatments may include, but are not limited to, surgical resection, radiation therapy, and traditional chemotherapy. As a result, these individuals do not have clinically measurable tumors. However, they are suspected of being at risk for disease progression near the original tumor site or through metastasis. This group can be further subdivided into high-risk and low-risk individuals. The subdivision is based on characteristics observed before and after initial treatment. These characteristics are known in the clinical field and are appropriately defined for each different neoplasm. Typical characteristics for the high-risk subgroup are tumor invasion into adjacent tissues or lymph node involvement.
[0248] Another group has a genetic predisposition to neoplasia but does not yet have documented clinical signs of the neoplasia. For example, a woman who tests positive for a genetic mutation associated with breast cancer but is still of childbearing age may wish to receive one or more of the immunoresponsive cells described herein in a prophylactic treatment to prevent the development of a neoplasia until it is appropriate to perform prophylactic surgery.
[0249] As a result of surface expression of an antigen-recognizing receptor that binds to a tumor antigen and a dominant-negative Fas polypeptide (e.g., an exogenous dominant-negative Fas polypeptide) that enhances the antitumor effect of cells containing the antigen-recognizing receptor and the dominant-negative Fas polypeptide, adoptively transferred T or NK cells are endowed with enhanced selective cytolytic activity at the tumor site. Furthermore, after their localization to the tumor or viral infection and their proliferation, T cells transform the tumor or viral infection site into a highly conducive environment for a wide range of immune cells (tumor-infiltrating lymphocytes, NK cells, NKT cells, dendritic cells, and macrophages) that participate in physiological antitumor or antiviral responses.
[0250] Additionally, the presently disclosed subject matter provides methods for treating and / or preventing a pathogen infection (e.g., a viral infection, a bacterial infection, a fungal infection, a parasitic infection, or a protozoan infection) in a subject, e.g., in an immunocompromised subject. The methods can include administering an effective amount of a cell of the present disclosure or a composition comprising the same to a subject having a pathogen infection. Exemplary viral infections amenable to treatment include, but are not limited to, cytomegalovirus (CMV), Epstein-Barr virus (EBV), human immunodeficiency virus (HIV), and influenza virus infections.
[0251] Further modifications can be introduced into the cells (e.g., T cells) of the present disclosure to avoid or minimize the risk of immunological complications (known as "malignant T cell transformation"), such as graft-versus-host disease (GvHD), or when healthy tissue expresses the same target antigen as tumor cells, resulting in outcomes similar to GvHD. A potential solution to this problem is to engineer a suicide gene into the cells of the present disclosure. Suitable suicide genes include, but are not limited to, herpes simplex virus thymidine kinase (hsv-tk), inducible caspase-9 suicide gene (iCasp-9), and truncated human epidermal growth factor receptor (EGFRt) polypeptide. In certain embodiments, the suicide gene is an EGFRt polypeptide. The EGFRt polypeptide can enable T cell elimination by administering an anti-EGFR monoclonal antibody (e.g., cetuximab). The EGFRt can be covalently linked upstream of the antigen-recognition receptor. The suicide gene can be included in a vector containing a nucleic acid encoding a CAR of the present disclosure. In this manner, administration of a prodrug (e.g., a prodrug (e.g., AP1903, which can activate iCasp-9) designed to activate a suicide gene during malignant T cell transformation (e.g., GVHD) triggers apoptosis in suicide gene-activating receptor-expressing (e.g., CAR-expressing) T cells. The incorporation of a suicide gene into an antigen recognition receptor (e.g., CAR) of the present disclosure provides an additional level of safety due to its ability to eliminate large numbers of receptor-expressing (e.g., CAR-expressing) T cells in a very short period of time. Cells (e.g., T cells) of the present disclosure that have an incorporated suicide gene can be preemptively eliminated at a given time point after T cell infusion or eradicated at the earliest sign of toxicity.
[0252] 10. Kit The presently disclosed subject matter provides kits for inducing and / or enhancing an immune response and / or treating and / or preventing a neoplasm or pathogen infection in a subject. In certain embodiments, the kits include an effective amount of the cells of the present disclosure or a pharmaceutical composition comprising the same. In certain embodiments, the kits include a sterile container; such a container may be a box, an ampoule, a bottle, a vial, a tube, a bag, a sachet, a blister pack, or any other suitable container format known in the art. Such a container may be made of plastic, glass, laminated paper, metal foil, or other material suitable for holding pharmaceuticals. In certain embodiments, the kits include a nucleic acid molecule encoding an antigen-recognition receptor (e.g., a CAR or TCR) directed against an antigen of interest and a nucleic acid molecule encoding an expressible form of a dominant-negative Fas polypeptide, optionally present on one or more vectors.
[0253] If desired, the cells and / or nucleic acid molecules are provided with instructions for administering the cells or nucleic acid molecules to a subject having or at risk of developing a neoplasm, pathogen, or immune disorder. The instructions generally include information about using the composition for the treatment and / or prevention of a neoplasm or pathogen infection.

The instructions may be printed directly on the container (if present), as a label affixed to the container, or as a separate sheet, pamphlet, card, or folder supplied in or with the container. [Example]
[0254] The practice of the present disclosure will employ, unless otherwise indicated, conventional techniques of molecular biology (including recombinant techniques), microbiology, cell biology, biochemistry, and immunology, which are well within the skill of those in the art. Such techniques are explained fully in the literature, e.g., "Molecular Cloning: A Laboratory Manual," 2nd ed. (Sambrook, 1989); "Oligonucleotide Synthesis" (Gait, 1984); "Animal Cell Culture" (Freshney, 1987); "Methods in Enzymology" and "Handbook of Experimental Immunology" (Weir, 1996); "Gene Transfer Vectors for Mammalian Cells" (Miller and Calos, 1987); "Current Protocols in Molecular Biology" (Ausubel, 1987); "PCR: The Polymerase Chain Reaction" (Mullis, 1994); and "Current Protocols in Immunology" (Coligan, 1991). These techniques are applicable to the production of the polynucleotides and polypeptides disclosed herein and thus may be considered in making and practicing the presently disclosed subject matter. Techniques particularly useful for particular embodiments are discussed in the sections that follow.
[0255] The following examples are put forth so as to provide those of ordinary skill in the art with a complete disclosure and description of how to make and use the cells and compositions of the present disclosure, and are not intended to limit the scope of what the inventors regard as their invention.
[0256] Example 1 - T cells modified with N-terminally mutated Fas DNR [Methods and Materials] Cell Culture: Jurkat76 and Platinum-GP retroviral packaging cells (Cell Biolabs) were cultured in RPMI supplemented with 10% fetal bovine serum, 10 mM HEPES (Gibco), and 25 units / ml PenStrep (Gibco). Primary T cells were cultured in RPMI supplemented with 10% heat-inactivated human serum, 25 mM HEPES (Gibco), and 50 units / ml PenStrep (Gibco). Single-clone selection of Fas CRISPR-edited Jurkat cells was performed by seeding 100 μl of cells per well in 96-well plates at a density of 0.5 cells per well. Cells were cultured for 3 weeks, and Fas surface expression was measured by flow cytometry.
[0257] Isolation and Expansion of Human T Cells. Buffy coats were obtained from healthy donors at the New York Blood Donation Center. Peripheral blood mononuclear cells (PBMCs) were isolated by density gradient centrifugation using Lymphocyte Separation Medium (Corning). CD8+ T cells were isolated using the EasySep Human CD8+ T Cell Isolation Kit (Stemcell). CD8+ T cells were activated with 5 μg / ml anti-CD3 (Miltenyi Biotec) antibody-coated plates and 1 μg / ml soluble anti-CD28 (Miltenyi Biotec). For viral transduction, T cells were treated with 50 IU / ml IL-2 (PeproTech) for 2 days prior to transduction.
[0258] [Plasmid Design and Viral Transduction] All plasmids for viral packaging were designed based on the SFGγ retroviral vector. The feline endogenous retroviral envelope RD114 was used for cotransduction of Platinum-GP cells with the SFGγ vector. Lipofectamine 3000 (ThermoFisher) was used for cotransduction of Platinum-GP cells. Jurkat cells and primary T cells were transduced with viral supernatant on Retronectin (Takara)-coated plates. Briefly, plates were coated with 20 μg / ml Retronectin overnight at 4°C and then blocked with 2% FBS in PBS for 30 minutes at room temperature. The plates were washed with PBS and loaded with viral supernatant. Centrifugation was performed at 2000 g for 2 hours at 32°C. The supernatant was aspirated, and cells were loaded into each well. The plates were again centrifuged at 1200 rpm for 5 minutes at 32°C and incubated at 37°C for 2 days.
[0259] [CRISPR editing] Single guide RNA (sgRNA) targeting Fas exon 2 was synthesized by Synthego using the 20-nt target sequence: GUGACUGACAUCAACUCCAA (SEQ ID NO: 66) (chemically modified). Briefly, 2 μl of 50 μM sgRNA was mixed with 1 μl of 20 μM recombinant Cas9 protein (Synthego) at room temperature for 10 minutes. One million Jurkat cells were resuspended in 17 μl of Nucleofector solution P3 (Lonza) and mixed with the sgRNA / Cas9 complex. Electroporation was performed using a Lonza 4D Nucleofector with AXP-1004 16-well strips (Lonza). The electroporation program was set as follows: Cell type: T cell human stimulation using code EC115. Fas expression after CRISPR editing was measured by flow cytometry 4 days after electroporation.
[0260] Sanger sequencing and sequence analysis: CRISPR editing efficiency was confirmed by analyzing sequence data from PCR amplicons using PCR primers: 5'-TCTATCATTCATGGTGCTGTTTC-3' (SEQ ID NO: 67) and 5'-AGGGGAACCAAAAACTGTAAAA-3' (SEQ ID NO: 68). KOD Hot Start Master Mix (EMD Millipore) was used for PCR products. PCR amplicon purification and sequencing services were provided by Genwiz. CRISPR-edited sequences were compared with wild-type control sequences using ICE sequencing software (Synthego).
[0261] [Flow cytometry and intracellular staining] Conjugated antibodies used for flow cytometry include Brilliant Violet 421. TM Antibodies used included anti-human EGFR (AY13, Biolegend), PE / Cy5 anti-human CD95 Fas (DX2, Biolegend), APC / Cyanine7 anti-human CD95 Fas (DX2, Biolegend), and PerCP / Cyanine5.5 anti-human TNF-α (Mab11, Biolegend). For NY-ESO targeting TCR, PE anti-TCRVβ13.1 (IMMU222, Beckman Coulter) was used. For CAR staining, Alexa Fluor 647 AffiniPure F(ab')2 fragment goat anti-mouse IgG, F(ab')2 antibody (Jackson ImmunoResearch) was used. Cell viability was assessed using LIVE / DEAD antibodies. TM The Fixable Aqua Dead Cell Stain kit (ThermoFisher) was used. For intracellular staining, Cytofix / Cytoperm TM A fixation / permeabilization solution kit (BD Biosciences) was used according to standard commercially available protocols.
[0262] FasL Apoptosis Assays: A soluble form of FasL oligomerized via the leucine zipper motif (FasL-LZ) was used at 100 ng / ml for all apoptosis assays. Cells were treated with FasL-LZ at designated time points at 37°C. Cells were washed and stained for surface antibodies. Cells were incubated in a CellEvent TM Cells were stained with Caspase-3 / 7 Green detection reagent (ThermoFisher) for 25 minutes at 37°C and washed twice. Cells were then stained with APC Annexin V (Biolegend) in Annexin V binding buffer (Biolegend) for 25 minutes at room temperature. Cells were washed twice and resuspended in Annexin V binding buffer for flow cytometry.
[0263] Statistical Analysis: All statistical analyses were performed using Prism7 (GraphPad) software. No statistical methods were used to predetermine sample size. All analyses were performed on triplicate samples. Statistical comparisons between two groups were calculated by the matched-sample paired Student's t-test. P<0.05 was considered statistically significant.
[0264] [result] The functionality of T cells modified with both FasDNR and CAR was evaluated. Two versions of the human FasDNR construct (see Figure 1A) were generated: a modular version and a combined version. Figure 1B demonstrates the activity of T cells containing the FasDNR construct. As shown in Figure 1B, 1928ζ1XXCAR inhibited the CD19 + FasDNR targeted malignant cells. FasDNR could protect T cells containing CAR and FasDNR from FasL-induced apoptosis. When administered together with cetuximab, it could target EGFRt and induce antibody-dependent cellular cytotoxicity (ADCC) or complement-dependent cytotoxicity.
[0265] Human Jurkat cells were retrovirally transduced with EGFRt alone or EGFRt / FasDNR. Cells were stained 2 days after transduction. As shown in Figure 1C, FasDNR and EGFRt expression were proportional in the transduced cells at a ratio of approximately 1:1.
[0266] Primary human CD8 + T cells were co-transduced with a TCR targeting the NY-ESO antigen. Cells with or without FasDNR were exposed to antigen for 6 hours before intracellular cytokine staining. The results of intracellular staining for TNFα are shown in Figure 1D. As shown in Figure 1D, FasDNR-transduced CD8 + Antigen-specific TNFα expression in T cells was not inferior to that in control cells not modified with FasDNR, a finding indicating that FasDNR does not reduce TNFα secretion in antigen-activated T cells.
[0267] Primary human CD8 + T cells were exposed to 100 ng / ml of FasL leucine zipper (FasL-lz) for the indicated time points. Activated caspase 3 / 7 and annexin V were used as early apoptosis markers. The results are shown in Figure 1E. As shown in Figure 1E, FasL stimulation induced apoptosis in 70% of cells without FasDNR, whereas <20% of cells underwent apoptosis in FasDNR-positive cells. This result suggests that FasDNR stimulates human CD8 + To confirm that T cells are protected from FasL-induced apoptotic signaling.
[0268] In summary, FasDNR protected cells from FasL-induced apoptosis without affecting T cell tumor-targeting function.
[0269] Using a CRISPR / Cas9 approach, a series of mutations were generated in the N-terminal region of Fas, and three major distinct T cell clones were identified: clone 15, which contained the wild-type Fas exon 2 sequence (having the amino acid sequence shown in SEQ ID NO: 10); clone 17, which contained a deletion of N31 and S32 in the N-terminal region compared to wild-type Fas (e.g., clone 15); and clone 19, which contained a biallelic 19-base frameshift deletion. See Figure 2C.
[0270] Jurkat cells were electroporated with recombinant Cas9 protein loaded with synthetic guide (sg) RNA targeting exon 2 of the human Fas gene. Approximately 3 weeks after electroporation, single-cell cloning was performed, and Fas surface expression was measured in the edited T cells. The results are shown in Figure 2A. As shown in Figure 2A, clone #15 (gray) represents unedited wild-type Fas cell surface expression. Clone #17 (open) showed a higher Fas expression level than the wild-type, while clone #19 (black) showed the lowest level of Fas. Figure 2B shows the average Fas expression levels from Figure 2A across triplicate samples. Clone #17 showed significantly higher Fas expression than clone #15.
[0271] In summary, clones 15, 17, and 19 showed different Fas expression levels. For example, the Fas expression level of clone 17 was higher than that of clones 15 and 19.
[0272] Next, the responsiveness of Jurkat cells containing clones 15, 17, or 19 to FasL stimulation was evaluated. The results are shown in Figures 3A and 3B. As shown in Figures 3A and 3B, clone 17 showed a sensitive response to FasL stimulation.
[0273] Jurkat cells were exposed to 100 ng / ml FasL-LZ for the indicated time points. Apoptosis was assessed. The results are shown in Figures 4A and 4B. As shown in Figures 4A and 4B, clone #15, which had unedited wild-type Fas, underwent apoptosis after FasL stimulation. Fas knockout clone #19 was resistant to apoptosis. In addition, clone #19 cells transduced with FasDNR were also protected from FasL-induced apoptosis.
[0274] In summary, Fas knockout clone #19 and FasDNR-transduced cells were protected from FasL-induced apoptosis.
[0275] As shown in Figure 5, a number of N-terminal mutants were constructed. Fas del32DNR consists of a deletion of amino acids at positions 32 and 230-314, and has the amino acid sequence shown in SEQ ID NO: 16. Fas del31-32DNR consists of a deletion of amino acids at positions 31 and 32 and 230-314, and has the amino acid sequence shown in SEQ ID NO: 18. Fas del32-33DNR consists of a deletion of amino acids at positions 32 and 33 and 230-314, and has the amino acid sequence shown in SEQ ID NO: 20. Fas S32A DNR consists of a deletion of amino acids at position 32 and 230-314, and has the amino acid sequence shown in SEQ ID NO: 24.

[0286] The transduction efficiency of clone #19 Fas knockout Jurkat cells with various Fas constructs was evaluated. Clone #19 Fas knockout Jurkat cells were transduced with Fas or FasDNR containing different N-terminal mutants and stained for Fas expression 3 days after test transduction. The results are shown in Figures 6A and 6B. As shown in Figures 6A and 6B, the Fas N-terminal mutants increased the Fas transduction efficiency.
[0287] Example 2 - Sensitivity of cells expressing FasDNR with S32 or N31S32 deletions to FasL-induced apoptosis [Methods and Materials] Human-derived Jurkat cells were retrovirally transduced with EGFRt / 1928z with or without Fas mutation. Using the Stemcell EasySep Human PE Positive Selection Kit II and a PE anti-human EGFR antibody (Biolegend, clone AY13), cells from the EGFRt-positive population were isolated 2 days post-transduction. On day 8 post-transduction, FasL-LZ (100 ng / ml) was used for apoptosis assays at designated time points at 37°C. Cells were washed twice with FACS buffer and stained for surface antibodies. Cells were incubated for 25 minutes at 37°C in CellEvent™ in FACS buffer. TM After staining with Caspase-3 / 7 Green detection reagent (ThermoFisher) and washing twice, cells were then stained with APC Annexin V (Biolegend) in Annexin V binding buffer (Biolegend) for 25 minutes at room temperature. Cells were washed twice and resuspended in Annexin V binding buffer for flow cytometry.
[0288] [result] Jurkat cells were treated with FasL on day 8 after transduction. As shown in Figures 7A and 7B, cells expressing FasD31DNR and FasD3132DNR were better protected from FasL-induced apoptosis (as indicated by the percentage of active caspase 3 / 7 and annexin V double-positive cells) than cells expressing FasDNR without the N-terminal mutation. p values were determined by unpaired Student's t-test ( ** p<0.01, *** p<0.001).
[0289] Example 3 - Human natural killer cells modified with N-terminally mutated FasDNR The utility and utility of N-terminal mutant FasDNR expression in human NK cells was investigated. Human NK cells were negatively isolated from human umbilical cord blood using magnetic beads. NK cells were cocultured with irradiated K562 (clone 9) feeder cells at a 1:2 ratio (NK cells vs. feeder cells). Medium supplemented with 200 IU / ml recombinant human IL-2 was added at activation and replaced every other day. Fas expression was determined by flow cytometry 5 days after activation. Upon activation, Fas expression was upregulated in human NK cells (see Figure 8). Results from triplicate cultures at rest and activation are shown as bar graphs + / - SEM. *** =P<0.001.
[0290] Fas expression levels were examined in human NK cells transduced with CAR, CAR-Fas DNR, or CAR-N-terminal mutant Fas DNR. The N-terminal mutant Fas DNR (designated "Fas DNR del31-32" or "Fas del31-32 DNR") contains deletions of amino acids 31 and 32 and 230-314, and is represented by the amino acid sequence shown in SEQ ID NO: 18. Human NK cells activated for 5 days were transduced with DMEM medium (untransduced control) or viral supernatant on retronectin-coated plates at 20 μg / ml to generate NK cells transduced with EGFRt / 1928z, EGFRt / 1928z / Fas DNR, or EGFRt / 1928z / Fas DNR del31-32. Excess irradiated feeder cells were replaced every other day. Cells were harvested 4 days after viral transduction for flow cytometry staining. *** =P<0.001. Figure 9 shows that human NK cells can be effectively transduced with FasDNR and N-terminal mutant FasDNR. Figure 10 shows that N-terminal mutant FasDNR-modified human NK cells significantly enhanced NK cell survival when exposed to recombinant FasL compared with FasDNR and unmodified NK cells.
