[Technical Field]
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of International Patent Application No. PCT / CN2023 / 071969, filed January 12, 2023, which is incorporated herein by reference in its entirety. [Background technology]
[0002] Lymphocyte depletion, currently part of CAR (chimeric antigen receptor) T-cell therapy, may involve administering cyclophosphamide or fludarabine to patients before infusion of CAR-T cells. This process prevents autologous lymphocytes from attacking the transferred CAR-T cells, prolonging the effectiveness of immune cell therapy. However, the process of removing many autologous lymphocytes makes the medical procedure more complicated, increases the patient's medical burden, and increases the risk of infection after treatment.
[0003] Some researchers have attempted to co-administer various cytokines to stimulate proliferation and help improve immune cell survival in vivo, but the drawback of this approach is that it may stimulate other unwanted lymphocytes to proliferate, increasing the risk of cytokine release syndrome (CRS).
[0004] There is a need in the art for new agents that can target and improve the proliferation and survival of selected cells. Summary of the Invention

[0079] In some cases, expressing a specific cytokine or combination of cytokines on the cell membrane includes introducing an exogenous nucleic acid molecule for expressing the specific cytokine or combination and an anchor structure, such that the specific cytokine or combination is expressed at a level higher than its naturally occurring expression level in the host cell or host organism. In other cases, introducing a specific cytokine or combination of cytokines and a tumor-targeting moiety (e.g., CAR) into T cells and expressing them on the cell membrane may include introducing a nucleic acid molecule containing a sequence encoding the specific cytokine or combination of cytokines and the tumor-targeting moiety (e.g., CAR) into immune cells, including T cells, NK cells, monocytes, macrophages, dendritic cells, etc. In some cases, the exogenous nucleic acid sequence encodes IL-12p40. In some cases, the exogenous nucleic acid sequence does not encode both IL-12p40 and IL-12p35. In some cases, the exogenous nucleic acid sequence does not encode a stimulus response element (SRE).
[0080] Without wishing to be bound by any particular theory, the cytokine-anchor materials disclosed herein can provide engineered immune cells with higher anti-tumor activity compared to engineered immune cells (such as CAR-T cells) that express a CAR alone (without expressing an exogenously introduced cytokine or combination of cytokines). When used in immunotherapy, the cytokine-anchor materials disclosed herein can achieve better therapeutic effects. The cytokine-anchor materials disclosed herein enable the expression of a cytokine or combination of cytokines on the cell membrane, thereby regulating the function of immune cells via a vector. When the vectors disclosed herein are introduced into immune cells, the resulting immune cells may have improved immunotherapeutic effects, including improved proliferation and survival rates compared to existing immune cells. By introducing a cytokine or a specific combination of cytokines, such as an interleukin, into immune cells and expressing that cytokine or specific combination of cytokines on the cell membrane together with a tumor-targeting moiety, such as a CAR, anti-tumor activity can be enhanced compared to expressing a tumor-targeting moiety (e.g., a CAR) alone, and in particular, the persistence and proliferation of engineered immune cells can be significantly improved. Delivery of engineered immune cells of cytokine-anchor materials to cancer patients can result in better therapeutic outcomes. In addition, the engineered immune cells of the present disclosure can provide various benefits, such as a reduction in the number of cells administered, given that they enhance antitumor activity without increasing the release of free cytokines, thereby reducing side effects such as cytokine release syndrome (CRS).
[0081] Without wishing to be bound by any particular theory, immobilizing specific cytokines or specific combinations of cytokines on the surface of immune cells can preserve cytokine activity and precisely stimulate immune cells in a targeted manner without inducing the secretion of additional cytokines that could cause severe CRS. Cytokines immobilized on the surface of immune cells according to some embodiments of the present disclosure can include different interleukins, such as IL-2, IL-4, IL-7, IL-9, IL-10, IL-12, IL-12p40, IL-15, IL-18, IL-21, IL-23, IL-27, IL-36γ, IL-23p19, or IL-1α, or variants thereof. Such cytokines immobilized on the cell membrane can improve the ability of immune cells to proliferate and survive.
[0082] Without wishing to be bound by any particular theory, combinations of different cytokines can be immobilized on the surface of immune cells, including combinations of different interleukins, such as IL-2, IL-4, IL-7, IL-9, IL-10, IL-12, IL-12p40, IL-15, IL-18, IL-21, IL-23, IL-27, IL-36γ, IL-23p19, or IL-1α, or variants thereof. Such combinations of cytokines immobilized on the cell membrane can further improve the ability of immune cells to proliferate and survive.
[0083] It should be understood that one, some, or all of the characteristics of the various embodiments described herein may be applied to any aspect unless the content clearly dictates otherwise. Moreover, various embodiments may be combined to form other embodiments of the present disclosure. These and other aspects of the present disclosure will be apparent to those skilled in the art. These and other embodiments of the present disclosure are further described in the detailed description that follows.
[0084] definition In this disclosure, whenever an embodiment is described herein with the word "comprising," other similar embodiments are also provided that are described with the terms "consisting of" and / or "consisting essentially of." All definitions set forth herein should be construed to refer to the definitions used throughout this specification and the appended claims, whether or not specifically referenced.
[0085] Throughout the specification and the appended claims, the singular forms "a," "an," and "the" include plural references unless the context clearly dictates otherwise. For example, the term "cells" includes plural samples, including mixtures thereof.
[0086] In the present disclosure, one, some, or all of the characteristics of the various embodiments described herein may be applied to any aspect unless the content clearly indicates otherwise. Furthermore, various embodiments may be combined to form other embodiments of the present disclosure. These and other aspects of the present disclosure will be apparent to those skilled in the art. These and other embodiments of the present disclosure are further described in the detailed description herein.
[0087] Unless otherwise defined throughout the specification and the appended claims, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure pertains. For example, the Concise Dictionary of Biomedicine and Molecular Biology, Juo, Pei-Show, 2nd ed., 2002, CRC Press; The Dictionary of Cell and Molecular Biology, 3rd ed., 1999, Academic Press; and the Oxford Dictionary of Biochemistry and Molecular Biology, Revised, 2000, Oxford University Press provide those skilled in the art with a general dictionary of many of the terms used in this disclosure.
[0088] Amino acids may be referred to herein by either their commonly known three letter symbols or by the one-letter symbols recommended by the IUPAC-IUB Biochemical Nomenclature Commission. Similarly, nucleotides may be referred to by their commonly accepted single-letter codes.
[0089] The numbering of amino acids in antibody variable domains, CDRs, and framework regions (FRs) follows the definition of Kabat as set forth in Kabat et al., Sequences of Proteins of Immunological Interest, 5th Ed. Public Health Service, National Institutes of Health, Bethesda, MD. (1991), unless otherwise indicated.
[0090] The term "about" or "approximately" means within an acceptable error range of a particular value as determined by one of ordinary skill in the art, which depends in part on how the value is measured or determined, i.e., the limitations of the measurement system. For example, "about" can mean within one standard deviation or more than one standard deviation, in accordance with practice in the art. Alternatively, "about" can mean a range of up to 20%, 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, preferably within 5-fold, and more preferably within 2-fold of a value. When particular values are described in this application and claims, unless otherwise specified, the term "about" should be assumed to mean within an acceptable error range of the particular value.
[0091] The terms "polypeptide," "oligopeptide," "peptide," and "protein" are used interchangeably herein to refer to polymers of amino acids of any length. A polymer can be linear or branched, can comprise modified amino acids, and can be interrupted by non-amino acids. The term also encompasses amino acid polymers that are modified, naturally or by intervention, for example, disulfide bond formation, glycosylation, lipidation, acetylation, phosphorylation, or any other manipulation or modification, such as conjugation with a labeling component. Also included within the definition are, for example, polypeptides containing one or more analogs of an amino acid (including, for example, unnatural amino acids), as well as other modifications known in the art. Because the polypeptides described herein are based on antibodies, it is understood that the polypeptides can occur as single chains or associated chains.
[0092] The term "amino acid" refers to natural, unnatural, and synthetic amino acids, including both the D or L optical isomers, and amino acid analogs and peptidomimetics. Amino acids are designated using standard one-letter or three-letter codes.
[0093] A "variant," as applied to a protein, is a protein having sequence homology to a naturally occurring biologically active protein that retains at least some of the therapeutic and / or biological activity of the biologically active protein. For example, a variant protein may share at least 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, or 99% amino acid sequence identity, or any range between at least 70% and 99%, compared to the reference biologically active protein. As used herein, "variant" can refer to a cytokine that has substantial or significant sequence identity or similarity to a naturally occurring cytokine, such as a naturally occurring cytokine described herein (e.g., IL-2, IL-4, etc.), and that retains one or more biological activities of the naturally occurring cytokine described herein (e.g., IL-2, IL-4, etc.) or an isoform of the naturally occurring cytokine described herein. A variant can include, for example, an alteration, substitution, deletion, addition, or chemical modification of one or more amino acids, one or more unnatural amino acids, or any combination thereof, of a parent peptide, such as a cytokine described herein (e.g., IL-2, IL-4, etc.), and can still retain the ability to specifically bind to its respective receptor, activate downstream targets, and / or induce one or more of the differentiation, proliferation (or death) and activity of cells, e.g., T cells and NK cells, to about the same extent, the same extent, or a greater extent than the parent peptide. Optionally, the variant is a cytokine. With respect to a parent cytokine, a variant can be at least about 80%, about 90%, about 95%, about 99% or more identical in amino acid sequence to the parent cytokine.
[0094] In the context of a polypeptide, a "linear sequence" or "sequence" is the order of amino acids in the polypeptide in the direction from amino terminus to carboxyl terminus, in which residues adjacent to each other in the sequence are contiguous in the primary structure of the polypeptide. A "subsequence" is a linear sequence of a portion of a polypeptide that is known to contain additional residues in one or both directions.
[0095] As used interchangeably herein, "polynucleotide" or "nucleic acid" refers to a polymer of nucleotides of any length, including DNA and RNA. The nucleotides can be deoxyribonucleotides, ribonucleotides, modified nucleotides or bases, and / or their analogs, or any substrate that can be incorporated into a polymer by DNA or RNA polymerase. A polynucleotide can contain modified nucleotides, such as methylated nucleotides and their analogs. If present, modifications to the nucleotide structure can be imparted before or after assembly of the polymer. The sequence of nucleotides can be interrupted by non-nucleotide components. A polynucleotide can be further modified after polymerization, such as by conjugation with a labeling component. Other types of modifications include, for example, "caps," substitution of one or more analogs of naturally occurring nucleotides, internucleotide modifications such as those with uncharged bonds (e.g., methylphosphonates, phosphotriesters, phosphoramidates, carbamates, etc.) and those with charged bonds (e.g., phosphorothioates, phosphorodithioates, etc.), those containing pendant moieties such as proteins (e.g., nucleases, toxins, antibodies, signal peptides, ply-L-lysine, etc.), those with intercalators (e.g., acridine, psoralens, etc.), those containing chelators (e.g., metals, radioactive metals, boron, metal oxides, etc.), those containing alkylators, those with modified linkages (e.g., alpha-anomeric nucleic acids, etc.), and unmodified forms of polynucleotides. Additionally, any of the hydroxyl groups normally present in the sugar may be replaced, for example, by phosphonate groups, phosphate groups, protected by standard protecting groups, or activated to prepare additional linkages to additional nucleotides, or conjugated to a solid support. The 5' and 3' terminal OH can be phosphorylated or substituted with amines or organic capping group moieties of 1 to 20 carbon atoms. Other hydroxyls can also be derivatized to standard protecting groups.Polynucleotides can further comprise ribose or deoxyribose sugar analogs commonly known in the art, including, for example, 2'-O-methyl-, 2'-O-allyl, 2'-fluoro-, or 2'-azido-ribose, carbocyclic sugar analogs, α-anomeric sugars, epimeric sugars such as arabinose, xylose, or lyxose, pyranose sugars, furanose sugars, sedoheptulose, acyclic analogs, and abasic nucleoside analogs such as methyl riboside. One or more phosphodiester linkages can be replaced by alternative linking groups. These alternative linking groups include embodiments in which the phosphate is replaced by P(O)S ("thioate"), P(S)S ("dithioate"), (O)NR2 ("amidate"), P(O)R, P(O)OR', CO, or CH2 ("formacetal"), where each R or R' is independently H, or a substituted or unsubstituted alkyl (1-20C) optionally containing an ether (-O-) linkage, aryl, alkenyl, cycloalkyl, cycloalkenyl, or araldyl. Not all linkages in a polynucleotide need be identical. The foregoing description applies to all polynucleotides referred to herein, including RNA and DNA.
[0096] The "variable region" of an antibody refers to the variable region of the antibody light chain or the variable region of the antibody heavy chain, either alone or in combination. The heavy and light chain variable regions each consist of four framework regions (FRs) connected by three complementarity-determining regions (CDRs), also known as hypervariable regions. The CDRs of each chain are held in close proximity by the FRs and, together with the CDRs of the other chain, contribute to the formation of the antigen-binding site of the antibody. There are at least two techniques for determining CDRs: (1) an approach based on interspecies sequence variability (i.e., Kabat et al., Sequences of Proteins of Immunological Interest, (5th ed., 1991, National Institutes of Health, Bethesda, MD)), and (2) an approach based on crystallographic studies of antigen-antibody complexes (Al-lazikani et al. (1997) J. Molec. Biol. 273:927-948). As used herein, CDRs may refer to CDRs defined by either approach or a combination of both approaches.
[0097] A "constant region" of an antibody refers to the constant region of the antibody light chain or the constant region of the antibody heavy chain, either alone or in combination.
[0098] A "host cell" includes an individual cell or cell culture that can be or has been a recipient of a vector containing an exogenous polynucleotide. A host cell includes the progeny of a single host cell, and the progeny may not necessarily be completely identical (in morphology or genomic DNA complement) to the original parent cell due to natural, accidental, or deliberate mutation. A host cell includes cells transfected in vivo with a polynucleotide of the present disclosure.
[0099] An "individual" or "subject" is a mammal, more preferably a human. Mammals also include farm animals, sport animals, pets, primates, horses, dogs, cats, mice, and rats.
[0100] As used herein, " vector " refers to the construct that can deliver and preferably express one or more genes or sequences of interest in host cell.Examples of vector include virus vector, naked DNA or RNA expression vector, plasmid, cosmid or phage vector, DNA or RNA expression vector that is associated with cationic condensing agent, DNA or RNA expression vector that is encapsulated in liposome, and certain eukaryotic cells, such as production cells.
[0101] The term "effective amount" or "therapeutically effective amount" refers to an amount of an agent sufficient to produce beneficial or desired results. The therapeutically effective amount may vary depending on one or more of the subject and disease state being treated, the subject's weight and age, the severity of the disease state, the mode of administration, etc., and can be easily determined by one skilled in the art. The term "effective amount" also applies to a dose that provides an image for detection by an appropriate imaging method. The specific dose may vary depending on one or more of the specific agent selected, the administration regimen to be followed, whether it is administered in combination with other compounds, the timing of administration, the tissue to be imaged, and the physical delivery system in which it is delivered. An effective amount of an active agent can be administered in a single dose or multiple doses.
[0102] As used herein, "pharmaceutically acceptable carrier" or "pharmaceutically acceptable excipient" includes any substance that, when combined with an active ingredient, allows the ingredient to retain its biological activity and is non-reactive with the subject's immune system. Examples include any of the standard pharmaceutical carriers, such as phosphate-buffered saline, water, emulsions such as oil / aqueous emulsions, and various types of wetting agents. Preferred diluents for aerosol or parenteral administration are phosphate-buffered saline or normal (0.9%) saline. Compositions containing such carriers are formulated by well-known conventional methods (see, for example, Remington's Pharmaceutical Sciences, 18th edition, A. Gennaro, ed., Mack Publishing Co., Easton, PA, 1990; and Remington, The Science and Practice of Pharmacy, 20th Ed., Mack Publishing, 2000).
[0103] Throughout the specification and the appended claims, the methods and systems of the present disclosure described herein may use conventional techniques and descriptions of molecular biology (including recombinant technology), cell biology, biochemistry, microarrays, and sequencing techniques that are within the skill of those skilled in the art, unless otherwise indicated. Such conventional techniques include polymer array synthesis, oligonucleotide hybridization and ligation, oligonucleotide sequencing, and hybridization detection using labels.

Before describing the present compositions, research tools, and systems and methods, it should be understood that this disclosure is not limited to the particular systems and methods, compositions, targets, and uses described, which may, of course, vary. It should also be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present disclosure, which is limited only by the appended claims.
[0104] The term "chimeric antigen receptor" or alternatively "CAR" refers in its simplest embodiment to a set of typically two polypeptides that, when present in an immune effector cell, provides the cell with specificity for a target cell, typically a cancer cell, and intracellular signal generation. In some embodiments, the CAR comprises at least an extracellular antigen-binding domain, a transmembrane domain, and a cytoplasmic signaling domain (also referred to herein as an "intracellular signaling domain") comprising a functional signaling domain of a stimulatory molecule and / or costimulatory molecule. Optionally, the set of polypeptides are contiguous with each other, e.g., in the same polypeptide chain, e.g., comprising a chimeric fusion protein. In some embodiments, the set of polypeptides are not adjacent to each other, e.g., in different polypeptide chains. In some embodiments, the set of polypeptides comprises a dimerization switch that, in the presence of a dimerization molecule, can couple the polypeptides to each other, e.g., couple the antigen-binding domain to the intracellular signaling domain. Optionally, the stimulatory molecule is a zeta chain associated with a T cell receptor complex. Optionally, the cytoplasmic signaling domain further comprises one or more functional signaling domains of at least one costimulatory molecule, as defined below. Optionally, the costimulatory molecule is selected from a costimulatory molecule described herein, e.g., 4-1BB (i.e., CD137), CD27, and / or CD28. Optionally, the CAR comprises a chimeric fusion protein comprising an extracellular antigen-binding domain, a transmembrane domain, and an intracellular signaling domain.
[0105] "Cytokine release syndrome" and "CRS" refer to an acute systemic inflammatory syndrome characterized by fever and multiple organ dysfunction associated with chimeric antigen receptor (CAR)-T cell therapy, therapeutic antibodies, and haploidentical allogeneic transplantation, as described, for example, in Frey N, Porter D. Cytokine Release Syndrome with Chimeric Antigen Receptor T Cell Therapy. Biol Blood Marrow Transplant 2019;25:e123.
[0106] In this disclosure, "antibody" refers to an immunoglobulin molecule capable of specifically binding to a target, such as a carbohydrate, polynucleotide, lipid, or polypeptide, via at least one antigen recognition site located in the variable region of the immunoglobulin molecule. As used herein, this term includes immunoglobulin molecules that specifically bind to an antigen and contain an FcR binding site, which may or may not be functional. As used in this disclosure, this term encompasses not only intact polyclonal or monoclonal antibodies, but also fragments thereof (e.g., Fab, Fab', F(ab')2, diabodies), Fv fragments, and single-chain (ScFv) mutants that contain the antigen recognition or binding site and have the ability to bind to the antigen. Antigen-binding antibody or immunoglobulin fragments are well known in the art, and such fragments may have a functional or non-functional Fc receptor binding site. Furthermore, as used herein, the term is not limited to only intact polyclonal or monoclonal antibodies, multispecific antibodies, e.g., bispecific or multispecific antibodies generated from at least two intact antibodies, chimeric antibodies, humanized antibodies, single-chain, chimeric, synthetic, recombinant, hybrid, mutated, grafted antibodies, human antibodies, and any other modified immunoglobulin molecule that contains an antigen-binding site, so long as the antibody exhibits the desired biological activity.
[0107] An antibody or CAR that "specifically binds" to an epitope is a term well understood in the art, and methods for determining such specific binding are also well known in the art. A molecule is said to exhibit "specific binding" if it reacts or associates more frequently, rapidly, for a longer duration, and / or with greater affinity with a particular cell, protein, or substance than with another cell, protein, or substance. An antibody "specifically binds" or "preferentially binds" to a target if it binds with greater affinity, avidity, ease, and / or duration than it binds to other substances. For example, an antibody that specifically or preferentially binds to CD19 is an antibody that binds to this epitope with greater affinity, avidity, ease, and / or duration than it binds to other epitopes. As a further example, an antibody (or another moiety) that specifically or preferentially binds to a first target may or may not specifically or preferentially bind to a second target. Thus, "specific binding" or "preferential binding" does not necessarily require (but can include) exclusive binding. Generally, although not necessarily always, reference to binding implies preferential binding.
[0108] A "fragment," as applied to a protein or polypeptide, is a truncated form of a native biologically active protein or polypeptide that may or may not retain at least some of its therapeutic and / or biological activity.
[0109] "TeIL," "tethered interleukin," "membrane-anchored cytokine," "membrane-bound cytokine," or "membrane-bound IL" may be used interchangeably to refer to the particular cytokine-anchor structures disclosed herein.
[0110] The term "sIL" refers to a secreted interleukin or cytokine that is neither membrane-anchored nor membrane-bound.
[0111] Sequence identity Sequence identity for cytokine-anchor material or any other amino acid sequence or nucleic acid sequence identified herein is defined as the percentage of amino acid residues (or nucleotides) in a query sequence that are identical to the amino acid residues of a second reference polypeptide sequence or a portion thereof (or a nucleotide or a portion thereof of a second reference nucleic acid sequence), after aligning the sequences and introducing gaps as necessary to achieve the maximum percent sequence identity and without considering conservative substitutions as part of the sequence identity.Alignment for the purpose of determining percent amino acid sequence identity or nucleic acid sequence identity can be achieved in a variety of ways within the skill of those in the art, for example, using publicly available computer software such as BLAST, BLAST-2, ALIGN, or Megalign (DNASTAR) software.Those skilled in the art can determine the appropriate parameters for measuring alignment, including any algorithms required to achieve maximum alignment over the entire length of the sequences being compared. Percent identity may be measured over the length of the entire defined polypeptide or nucleic acid sequence, or over a shorter length, for example, over a fragment taken from a larger defined polypeptide or nucleic acid sequence, such as a fragment of at least 15, at least 20, at least 30, at least 40, at least 50, at least 70, or at least 150 consecutive residues or base pairs or nucleotides. Such lengths are exemplary only, and it is understood that any fragment length supported by the sequences shown herein in the tables, figures, or sequence listing can be used to describe the length over which percent identity can be measured. In some embodiments, percent identity is determined over the entire length of a prominent reference sequence, such as the sequences provided herein.For example, sequence comparison between two amino acid sequences (or shorter lengths) of the present disclosure can be performed using the computer program Blastp (protein-protein BLAST) provided online by the National Center for Biotechnology Information (NCBI). The percentage amino acid sequence identity of a given amino acid sequence A to a given amino acid sequence B (which can be translated as a given amino acid sequence A having a specific % amino acid sequence identity to a given amino acid sequence B) is calculated by the following formula:
[0112]
number
[0113] Two polynucleotide or polypeptide sequences are said to be "identical" if the sequence of nucleotides or amino acids in the two sequences is the same when aligned for maximum correspondence as described below. Comparisons between two sequences are typically performed by comparing the sequences over a comparison window to identify and compare local regions of sequence similarity.
[0114] signal peptide In some embodiments, provided herein is a signal peptide present as part of a polypeptide described in the present disclosure, including a polypeptide in a single cytokine-anchor material, a first and second polypeptide in two cytokine-anchor materials, and a first, second, and third polypeptide in three cytokine-anchor materials. Optionally, the signal peptide is removed during protein processing from the polypeptide to form the protein in the single cytokine-anchor material, from the first and second polypeptides to form the first and second proteins, respectively, in the two cytokine-anchor materials, or from the first, second, and third polypeptides to form the first, second, and third proteins, respectively, in the three cytokine-anchor materials.
[0115] The signal peptide can be encoded by a signal peptide nucleic acid sequence, which can be present as part of the nucleic acid sequences described in this disclosure, including the nucleic acid sequence in a single cytokine-anchor material, the first and second nucleic acid sequences in two cytokine-anchor materials, and the first, second, and third nucleic acid sequences in three cytokine-anchor materials.
[0116] A signal peptide can be any suitable peptide capable of directing a polypeptide described herein to a specific compartment of a cell containing such a polypeptide, such as the cell's membrane. In some embodiments, a signal peptide includes a peptide that directs intracellular delivery and localization of the peptide and any linked polypeptide to a specific organelle (such as the endoplasmic reticulum) and / or the cell surface. As used herein, the term "signal peptide" or "signal peptide sequence" refers to a peptide sequence that can be present at the N-terminus of a newly synthesized secreted polypeptide or a newly synthesized transmembrane polypeptide. The signal peptide can translocate the polypeptide through or within the cell's plasma membrane. The signal can then be removed. Specifically, the signal peptide can direct the polypeptide into the cell's secretory pathway.
[0117] Optionally, the signal peptide may be a peptide of any secreted or transmembrane protein that directs delivery of the polypeptides disclosed herein to the cell membrane and cell surface, resulting in accurate localization of the polypeptides of the present disclosure. Optionally, the signal peptide directs the polypeptides of the present disclosure to the cell membrane, where the extracellular portion of the polypeptide is displayed on the cell surface. Optionally, the transmembrane portion spans the plasma membrane, and the active domain is located in the cytoplasm or inside the cell. In some embodiments, the signal peptide is cleaved after passing through the endoplasmic reticulum and is called a cleavable signal peptide. Optionally, the signal peptide may have an amino acid at its end that is recognized and cleaved by a signal peptidase. The signal peptidase can cleave the signal peptide during or after translocation, resulting in a free signal peptide and a mature protein. The free signal peptide can then be digested by a specific protease.
[0118] In some embodiments, the signal peptide is a type I, type II, type III, or type IV transmembrane protein. In some embodiments, the signal peptide comprises an immunoglobulin heavy chain signal peptide.
[0119] Optionally, when another component of the cytokine-anchor material, such as a cytokine and / or CAR, is expressed in a cell (e.g., an engineered immune cell), a signal peptide expressed together with the component in the same polypeptide directs the nascent protein to the endoplasmic reticulum and then to the cell surface, thus allowing the component of the cytokine-anchor material to be expressed on the cell surface. Optionally, the core of the signal peptide consists of a long stretch of hydrophobic amino acids that tend to form an α-helix. Optionally, the signal peptide begins with a short stretch of positively charged amino acids, which helps to ensure the correct topology of the polypeptide during translocation. The signal peptide can be at the N-terminus of the polypeptide. In some embodiments, when a cell expresses a membrane-anchored cytokine and / or CAR, the signal sequence can be excised from the membrane-anchored cytokine and / or CAR.
[0120] Without wishing to be bound by any particular theory, a signal peptide can promote expression of a membrane-anchored cytokine and / or CAR, and the presence of a signal peptide in an expressed membrane-anchored cytokine and / or CAR can contribute to membrane anchoring of the cytokine and / or CAR, but the presence of a signal peptide may be unrelated to the function of the cell membrane-anchored cytokine and / or CAR.
[0121] In some embodiments, the signal peptide is a signal peptide derived from a transmembrane protein. In some embodiments, the signal peptide comprises a CD4 signal peptide, a Cd8α signal peptide, a CD28 signal peptide, a CD33 signal peptide, a CD137 (4-1BB) signal peptide, an IL-2 signal peptide, an IgE signal peptide, an IgG1 signal peptide, a GM-CSF signal peptide, an HLA-A signal peptide, an HLA signal peptide, a TCR signal peptide, or a β2M signal peptide, or a combination thereof.

The cytokines or cytokine peptides present as part of the polypeptides are operably linked to the anchor structures described herein. The anchor structures can bind the cytokine to the membrane of a cell.
[0129] The cytokine can be encoded by a cytokine nucleic acid sequence, which can be present as part of the nucleic acid sequences described in the present disclosure, including a nucleic acid sequence in a single cytokine-anchor material, a first nucleic acid sequence and a second nucleic acid sequence in two cytokine-anchor materials, and a first nucleic acid sequence, a second nucleic acid sequence, and a third nucleic acid sequence in three cytokine-anchor materials.
[0130] In various embodiments, the term "cytokine" can include a full-length cytokine or interleukin, or a fragment (e.g., truncated form) or variant thereof that substantially retains the biological activity of the corresponding wild-type cytokine or interleukin (e.g., has a biological activity that is at least 80%, at least 90%, at least 95%, at least 98%, at least 99%, or at least 100% of the biological activity of the corresponding wild-type cytokine or interleukin). Cytokines can be secreted by immune cells (e.g., monocytes, macrophages, T cells, B cells, NK cells, etc.). Cytokines can be secreted by certain non-immune cells (e.g., endothelial cells, epithelial cells, fibroblasts, etc.). Cytokines can be produced by monocytes, macrophages, B cells, dendritic cells, TH1 and TH2, mast cells, NK cells, and bone marrow stromal cells. Cytokines can have the ability to regulate multiple cellular and bodily functions, including innate and adaptive immunity, hematopoiesis, cell proliferation, APSC pluripotent cells, and damaged tissue repair and other functions.

In some embodiments, the non-peptide anchor can be attached to a protein during protein processing. In some embodiments, the non-peptide anchor can be attached to a protein by replacing the non-peptide anchor attachment signal located at the C-terminus of the protein.
[0160] The non-peptide anchors provided herein can include lipids such as glycolipids. Glycolipids can be lipids with carbohydrates linked by glycosidic bonds. Glycolipids can maintain the stability of cell membranes. Glycolipids can promote cell recognition. Glycolipids can be located on the surface of all eukaryotic cell membranes.

[0222] Nucleic Acid Molecules, Vectors, and Systems According to an aspect of the present disclosure, provided herein is a nucleic acid molecule encoding a polypeptide described in this disclosure.
[0223] From the primary amino acid sequence of the polypeptide(s) encoding the cytokine-anchor protein constructs provided herein, or any component thereof, one skilled in the art can determine the appropriate nucleotide sequence(s) encoding the polypeptide(s), and, if necessary, codon-optimized (see, e.g., Mauro and Chappell. Trends Mol Med. 20(11):604-613, 2014).
[0224] The nucleic acid molecule(s) encoding the polypeptides in the cytokine-anchor material, such as in some embodiments of the present disclosure, may be or be part of a vector (e.g., a plasmid, cosmid, or viral vector, or an artificial chromosome, etc.), which may include other functional regions (elements), such as one or more promoters, one or more origins of replication, one or more selectable marker(s), and one or more other elements typically found in expression vectors. Cloning and expression of nucleic acids encoding proteins, including CARs and cytokines, is well established and within the skill of one of ordinary skill in the art.
[0225] In some embodiments, the nucleic acid molecules of the cytokine-anchor material are more than 80% pure, eg, more than 90%, more than 95%, more than 97%, and more than 99% pure.
[0226] In some embodiments, vectors containing one or more of the nucleic acid sequences described in this disclosure are provided herein. The vector may be a transfer vector, which refers to a composition containing an isolated nucleic acid and can be used to deliver the isolated nucleic acid to the interior of a cell. Many vectors are known in the art, including linear polynucleotides, polynucleotides associated with ionic or amphiphilic compounds, plasmids, and viruses. "Transfer vector" includes self-replicating plasmids or viruses. This term should be interpreted to further include non-plasmid and non-viral compounds that facilitate the transfer of nucleic acids into cells, such as polylysine compounds and liposomes. Examples of viral transfer vectors include adenoviral vectors, adeno-associated virus vectors, retroviral vectors, lentiviral vectors, and the like. Vectors can include expression vectors, which refer to vectors containing a recombinant polynucleotide comprising an expression control sequence operably linked to the nucleotide sequence to be expressed. Expression vectors contain sufficient cis-acting elements for expression; other elements for expression can be supplied by the host cell or in an in vitro expression system. Expression vectors include all those known in the art, including cosmids, plasmids (e.g., naked or contained in liposomes), and viruses (e.g., lentiviruses, retroviruses, adenoviruses, and adeno-associated viruses) that incorporate the recombinant polynucleotide.
[0227] In some embodiments, the nucleic acid molecules described herein are vectors. In some embodiments, the vectors are viral vectors. In some embodiments, the vectors are retroviral vectors, lentiviral vectors, adenoviral vectors, or adeno-associated viral vectors.
[0228] In some embodiments, the vector is a retroviral vector.Retroviral vector generally refers to an RNA virus that can reverse transcribe the complementary strand of DNA in infected cells, use this single strand of DNA as a template to synthesize a second strand of DNA, and then integrate it into the cell genome in DNA.Retroviral vectors can use host cell enzymes to transcribe and replicate RNA, synthesize proteins, repackage the virus, and release it from cells to become infectious virus.The transduction efficiency of retroviruses can be high, and retroviral vectors can effectively improve the transfection rate of genes.
[0229] In some embodiments, the vector is a lentiviral vector. Lentiviral vector refers to a gene therapy vector developed based on HIV-1 (human immunodeficiency virus type 1). Lentiviral vectors can infect both dividing and non-dividing cells. They can effectively infect almost all mammalian cells, including neuronal cells, hepatocytes, etc., with high infection efficiency. Lentiviruses can efficiently integrate foreign genes into host chromosomes to achieve sustained expression.
[0230] In some embodiments, the vector is a transposon plasmid.Transposon plasmid generally refers to the basic unit that exists on chromosomal DNA and can autonomously replicate and replace.Transposon plasmid can "jump" from one position to another in genome through a series of processes such as excision and reintegration.
[0231] In some embodiments, the vector is an expression vector. In some embodiments, the expression vector comprises a nucleic acid sequence encoding a targeting moiety (e.g., a CAR). In some embodiments, the expression vector comprises a nucleic acid sequence encoding a cytokine and an anchor structure. In some embodiments, the expression vector comprises a nucleic acid sequence encoding a CAR, a cytokine, and an anchor structure. In some embodiments, the expression vector comprises a second nucleic acid sequence encoding a second cytokine and a second anchor structure.

In some embodiments, the expression vector comprises a third nucleic acid sequence encoding a third cytokine and a third anchor structure. In some embodiments, the expression vector comprises a third nucleic acid sequence encoding a third CAR, a third cytokine, and a third anchor structure. In some embodiments, nucleic acid sequences within the expression vector can be positioned upstream or downstream. Specifically, the nucleic acid encoding the cytokine and the anchor structure can be positioned upstream or downstream of the nucleic acid encoding the CAR molecule. The nucleic acid encoding the CAR and the nucleic acid encoding the cytokine can be linked via a cleavable linker nucleic acid sequence encoding a 2A peptide or an IRES.
[0232] In some embodiments, the nucleic acid molecules and / or vectors of the present disclosure are introduced into host cells. For eukaryotic cells, suitable techniques include, for example, calcium phosphate transfection, DEAE-dextran, electroporation, liposome-mediated transfection, and transduction using retroviruses or other viruses, such as vaccinia, or baculovirus for insect cells. In some cases, the introduction of nucleic acids into host cells, particularly eukaryotic cells, uses a virus- or plasmid-based system. In some cases, the plasmid system is maintained episomally. In other cases, the plasmid system is integrated into the host cell or into an artificial chromosome. In certain embodiments, integration is by random integration of one or more copies at a single or multiple loci. In some embodiments, integration is by targeted integration of one or more copies at a single or multiple loci. For bacterial cells, suitable techniques include, for example, calcium chloride transformation, electroporation, and transfection using bacteriophage.

The lipid-associated nucleic acid molecule can be encapsulated in the aqueous interior of the liposome, dispersed within the lipid bilayer of the liposome, bound to the liposome via a linking molecule associated with both the liposome and the oligonucleotide, entrapped in the liposome, complexed with the liposome, dispersed in a solution containing lipids, mixed with lipids, combined with lipids, contained as a suspension in lipids, contained with or complexed to micelles, or otherwise associated with lipids. The lipid, lipid / DNA, or lipid / expression vector-associated compositions are not limited to any particular structure in solution. For example, they can exist in a bilayer structure, as micelles, or in a "folded" structure. They are simply dispersed in the solution, sometimes forming aggregates that are not uniform in size or shape. Lipids are fatty substances that can be naturally occurring or synthetic. For example, lipids include the lipid droplets that occur naturally in the cytoplasm, as well as a class of compounds that contain long-chain aliphatic hydrocarbons and their derivatives, such as fatty acids, alcohols, amines, aminoalcohols, and aldehydes.
[0249] Suitable lipids for use can be obtained from commercial sources. For example, dimyristyl phosphatidylcholine ("DMPC") can be obtained from Sigma (St. Louis, MO), dicetyl phosphate ("DCP") can be obtained from K&K Laboratories (Plainview, NY), cholesterol ("Choi") can be obtained from Calbiochem-Behring, and dimyristyl phosphatidylglycerol ("DMPG") and other lipids can be obtained from Avanti Polar Lipids, Inc. (Birmingham, AL). Stock solutions of lipids in chloroform or chloroform / methanol can be stored at approximately -20°C. Chloroform is used as the sole solvent because it evaporates more readily than methanol. "Liposome" is a generic term that includes a variety of unilamellar and multilamellar lipid vesicles formed by the formation of enclosed lipid bilayers or aggregates. Liposomes can be characterized as vesicular structures with a phospholipid bilayer membrane and an internal aqueous medium. Multilamellar liposomes have multiple lipid layers separated by aqueous medium. They form spontaneously when phospholipids are suspended in an excess of aqueous solution. The lipid components undergo self-rearrangement before forming a closed structure, trapping water and dissolved solutes between the lipid bilayers (Ghosh et al., 1991 Glycobiology 5:505-10). However, compositions with structures in solution that differ from the typical vesicular structure are also encompassed. For example, lipids may adopt a micellar structure or simply exist as heterogeneous aggregates of lipid molecules. Lipofectamine-nucleic acid complexes are also contemplated.
[0250] Regardless of the method used to introduce the nucleic acid molecules, vectors, or systems described herein into host cells, various assays can be performed to confirm the presence of the recombinant DNA sequence in the host cell. Such assays include, for example, "molecular biological" assays well known to those skilled in the art, such as Southern and Northern blotting, RT-PCR and PCR, and "biochemical" assays, such as detecting the presence or absence of specific peptides by immunological means (ELISA and Western blot), or by the assays described herein to identify agents within the scope of the present disclosure.

[0252] In some embodiments, the nucleic acid molecule of the present disclosure, including a vector nucleic acid comprising a nucleic acid sequence encoding a CAR or cytokine-anchor polypeptide of the present disclosure, is present in an isolated host cell. Optionally, the host cell is part of a clonal population of host cells. As used herein, reference to a host cell also encompasses a clonal population of cells. A clonal population is one that has been propagated from a single parent host cell. Optionally, the host cell is derived from any suitable organism. In some embodiments, the host cell is, for example, a bacterium, yeast, fungus, or mammalian cell. In some embodiments, the host cell is an immune cell or a tumor cell. In some embodiments, the host cell is an engineered immune cell. In some embodiments, the host cell is a T cell. In some embodiments, the host cell is a tumor-infiltrating lymphocyte (TIL). In some embodiments, the engineered immune cell is a natural killer (NK) cell.

[0254] Cell Source Prior to expansion and genetic or other modification, a source of cells, such as T cells or natural killer (NK) cells, can be obtained directly or indirectly from a subject. Examples of subjects include humans, monkeys, chimpanzees, dogs, cats, mice, rats, and transgenic species thereof. T cells can be obtained from many sources, including peripheral blood mononuclear cells, bone marrow, lymph node tissue, umbilical cord blood, thymus tissue, tissue from an infection site, ascites, pleural effusion, spleen tissue, and tumors. In the case of the present disclosure, immune effector cells, such as T cells, can be obtained from a blood unit collected from a subject using any number of techniques known to those skilled in the art, such as Ficoll™ separation. In some cases, cells from an individual's circulating blood are obtained by apheresis. The apheresis product may contain lymphocytes, including T cells, monocytes, granulocytes, B cells, other nucleated white blood cells, red blood cells, and platelets. Optionally, cells collected by apheresis can be washed to remove the plasma fraction and, optionally, placed in an appropriate buffer or medium for subsequent processing. Optionally, cells are washed with phosphate-buffered saline (PBS). In other cases, the wash solution lacks calcium, may lack magnesium, or may lack many, if not all, divalent cations. An initial activation step in the absence of calcium can result in expanded activation. As those skilled in the art will readily appreciate, washing steps can be accomplished by methods known to those skilled in the art, for example, by using a semi-automated "flow-through" centrifuge (e.g., a Cobe 2991 cell processor, a Baxter CytoMate, or a Haemonetics Cell Saver 5) according to the manufacturer's instructions. After washing, cells can be resuspended in various biocompatible buffers, such as Ca-free, Mg-free PBS, PlasmaLyte A, or other saline solutions with or without buffers. Alternatively, undesirable components of the apheresis sample can be removed and the cells resuspended directly in culture medium.
[0255] Optionally, T cells are isolated from peripheral blood lymphocytes by lysing red blood cells and depleting monocytes, for example, by centrifugation through a PERCOLL™ gradient or by counterflow centrifugal elutriation.
[0256] The method can include selecting a particular subpopulation of immune effector cells, e.g., T cells, that are CD25+ depleted cells, e.g., a T regulatory cell-depleted population, e.g., using negative selection techniques. Preferably, the population of T regulatory depleted cells contains less than 30%, 25%, 20%, 15%, 10%, 5%, 4%, 3%, 2%, 1% CD25+ cells.
[0257] In some embodiments, T regulatory cells, e.g., CD25+ T cells, are removed from the population using an anti-CD25 antibody or fragment thereof, or the CD25-binding ligand IL-2. In some embodiments, the anti-CD25 antibody or fragment thereof, or the CD25-binding ligand, is conjugated to or otherwise coated on a substrate, e.g., a bead. In some embodiments, the anti-CD25 antibody or fragment thereof is conjugated to a substrate described herein.
[0258] In some embodiments, T regulatory cells, eg, CD25+ T cells, are removed from the population using a CD25 depletion reagent from Militenyi™.
[0259] In some embodiments, T regulatory cells, e.g., CD25+ cells, are removed from the population using a CliniMAC system with a depletion tubing set, e.g., tubing 162-01. In some embodiments, the CliniMAC system is run in a depletion setting, e.g., DEPLETION2.1.
[0260] The methods described herein can include more than one selection step, for example, more than one depletion step. Enrichment of a T cell population by negative selection can be achieved, for example, by using a combination of antibodies against surface markers specific to the negatively selected cells. One method is cell sorting and / or selection by negative magnetic immunoadhesion or flow cytometry, using a cocktail of monoclonal antibodies against cell surface markers present on the negatively selected cells. For example, to enrich CD4+ cells by negative selection, the monoclonal antibody cocktail can include antibodies against CD14, CD20, CD11b, CD16, HLA-DR, and CD8.
[0261] Without wishing to be bound by a particular theory, providing a subject with immune cells having a CAR and cytokine-anchor as described herein reduces the level of negative regulators of immune cells in the subject prior to apheresis or during the manufacture of the CAR-expressing cell product, which can also reduce the risk of relapse in the subject (e.g., unwanted immune cells, e.g., T REG This can reduce the risk of recurrence in a subject while reducing or eliminating the need for a treatment (reducing the number of cells). In some cases, providing a subject with immune cells having a CAR and cytokine-anchor as described herein can reduce the risk of recurrence in a subject without the process of eliminating specific immune cells in the subject (i.e., without the process of lymphodepletion). REG General methods for depleting cells are known in the art. REG Methods for reducing cells include cyclophosphamide, anti-GITR antibodies (anti-GITR antibodies described herein), CD25 depletion, and combinations thereof.
[0262] In some embodiments, the manufacturing method includes administering a T cell to a subject prior to production of the CAR-expressing cells. REG In some embodiments, the production method does not involve reducing (e.g., depleting) the number of T cells prior to producing the CAR-expressing cells.REG For example, a manufacturing method can include contacting a sample, e.g., an apheresis sample, with an anti-GITR antibody and / or an anti-CD25 antibody (or fragment thereof, or a CD25-binding ligand), thereby reducing (e.g., partially depleting) the CAR-expressing cells (e.g., T cells, NK cells) prior to manufacturing the CAR-expressing cell (e.g., T cell, NK cell) product. REG The method includes a step of partially depleting the cells.
[0263] In some embodiments, the subject is treated with T REG Although not pre-treated with one or more cell-reducing therapies, the subject still has a reduced risk of relapse to CAR-expressing cell treatment due to co-expression of a CAR and cytokine-anchor. In some embodiments, the subject is treated with T REG The subject may have been previously treated with one or more therapies that partially deplete the cells, thereby further reducing the subject's risk of relapse to CAR-expressing cell treatment.
[0264] In some embodiments, the subject is not pre-treated with cyclophosphamide prior to collection of cells for CAR-expressing cell product manufacturing, yet the co-expression of a CAR and a cytokine-anchor still reduces the subject's risk of relapse to CAR-expressing cell treatment. In some embodiments, the subject is pre-treated with cyclophosphamide prior to collection of cells for CAR-expressing cell product manufacturing, thereby further reducing the subject's risk of relapse to CAR-expressing cell treatment due to the co-expression of a CAR and a cytokine-anchor. In some embodiments, the subject is not pre-treated with an anti-GITR antibody prior to collection of cells for CAR-expressing cell product manufacturing, yet the co-expression of a CAR and a cytokine-anchor still reduces the subject's risk of relapse to CAR-expressing cell treatment. In some embodiments, the subject is pre-treated with an anti-GITR antibody prior to collection of cells for CAR-expressing cell product manufacturing, thereby further reducing the subject's risk of relapse to CAR-expressing cell treatment due to the co-expression of a CAR and a cytokine-anchor.
[0265] In some embodiments, other cell populations can be optionally removed, such as those that adversely affect the proliferation and / or function of CAR-T cells, e.g., cells expressing CD14, CD11b, CD33, CD15, or other markers potentially expressed by immunosuppressive cells.
[0266] The method can further include removing cells expressing tumor antigens, such as tumor antigens that do not contain CD25, such as CD30, CD38, CD123, CD20, CD14, or CD11b, from the population, thereby providing a population of T regulatory depleted cells, such as CD25+ depleted cells, and tumor antigen depleted cells suitable for expressing a CAR, such as CAR19, and a cytokine anchor. In some embodiments, tumor antigen-expressing cells are removed simultaneously with T regulatory, such as CD25+ cells. For example, an anti-CD25 antibody or fragment thereof and an anti-tumor antigen antibody or fragment thereof can be bound to the same substrate, such as beads, that can be used to remove cells, or an anti-CD25 antibody or fragment thereof, or an anti-tumor antigen antibody or fragment thereof, can be bound to separate beads, and a mixture thereof can be used to remove cells. In some embodiments, the removal of T regulatory cells, such as CD25+ cells, and the removal of tumor antigen-expressing cells are sequential, for example, can be performed in either order.
[0267] Also provided are methods that include removing cells expressing a checkpoint inhibitor, e.g., a checkpoint inhibitor described herein, e.g., one or more of PD1+ cells, LAG3+ cells, and TIM3+ cells, from the population, thereby providing a population of T regulatory-depleted cells, e.g., CD25+-depleted cells, and checkpoint inhibitor-depleted cells, e.g., PD1+, LAG3+, and / or TIM3+-depleted cells. Exemplary checkpoint inhibitors include B7-H1, B&-1, CD160, P1H, 2B4, PD1, TIM3, CEACAM (e.g., CEACAM-1, CEACAM-3, and / or CEACAM-5), LAG3, TIGIT, CTLA-4, BTLA, and LAIR1. In some embodiments, checkpoint inhibitor-expressing cells are removed simultaneously with T regulatory, e.g., CD25+ cells. For example, an anti-CD25 antibody or fragment thereof and an anti-check point inhibitor antibody or fragment thereof can be attached to the same bead that can be used to remove cells, or an anti-CD25 antibody or fragment thereof, or an anti-check point inhibitor antibody or fragment thereof, can be attached to separate beads, a mixture of which can be used to remove cells. In some embodiments, the removal of T regulatory cells, e.g., CD25+ cells, and the removal of check point inhibitor-expressing cells are sequential, e.g., can occur in either order.
[0268] The methods described herein can include a positive selection step. For example, T cells can be isolated by incubation with anti-CD3 / anti-CD28 (e.g., 3x28) conjugated beads, such as DYNABEADS® M-450 CD3 / CD28 T, for a time sufficient for positive selection of the desired T cells. In one embodiment, the time is approximately 30 minutes. In a further embodiment, the time ranges from 30 minutes to 36 hours or more, and all integer values therebetween. In a further embodiment, the time is at least 1, 2, 3, 4, 5, or 6 hours. In yet another preferred embodiment, the time is 10 to 24 hours. In one embodiment, the incubation time is 24 hours. In any situation where T cells are scarce compared to other cell types, such as when isolating tumor-infiltrating lymphocytes (TILs) from tumor tissue or immunocompromised individuals, longer incubation times can be used to isolate T cells. Furthermore, longer incubation times can increase the efficiency of CD8+ T cell capture. Thus, by simply shortening or lengthening the time that T cells are allowed to bind to the CD3 / CD28 beads, and / or by increasing or decreasing the ratio of beads to T cells (as further described herein), subpopulations of T cells can be preferentially selected for or eliminated at the beginning of culture or at other times during the process. Additionally, by increasing or decreasing the ratio of anti-CD3 and / or anti-CD28 antibodies on the beads or other surfaces, subpopulations of T cells can be preferentially selected for or eliminated at the beginning of culture or at other desired times.
[0269] In some embodiments, T cell populations can be selected that express one or more of IFN-γ, TNFα, IL-17A, IL-2, IL-3, IL-4, GM-CSF, IL-10, IL-13, granzyme B, and perforin, or other suitable molecules, e.g., other cytokines. Methods for screening cell expression can be defined, for example, by the methods described in U.S. Patent Application Publication No. US20220056116A1, which is incorporated herein by reference in its entirety.
[0270] For the isolation of a desired cell population by positive or negative selection, the concentration of cells and surfaces (e.g., particles such as beads) can be varied. In some embodiments, it may be desirable to significantly reduce the volume in which the beads and cells are mixed (e.g., increase the concentration of cells) to ensure maximum contact between the cells and beads. For example, a concentration of about 10 billion cells / ml, 9 billion / ml, 8 billion / ml, 7 billion / ml, 6 billion / ml, or 5 billion / ml is used. In one embodiment, a concentration of 1 billion cells / ml is used. In one embodiment, a cell concentration from 75 million, 80 million, 85 million, 90 million, 95 million, or 100 million cells / ml is used. In a further embodiment, a concentration of 1.25 or 1.5 billion cells / ml can be used.
[0271] The use of high concentrations can increase cell yield, cell activation, and cell proliferation. Furthermore, the use of high cell concentrations allows for more efficient capture of cells that may weakly express a target antigen of interest, such as CD28-negative T cells, or from samples containing many tumor cells (e.g., leukemia blood, tumor tissue, etc.). Such cell populations may have therapeutic value and are desirable to obtain. For example, the use of high cell concentrations allows for more efficient selection of CD8+ T cells, which typically have weaker CD28 expression.
[0272] In some embodiments, it may be desirable to use lower concentrations of cells. By significantly diluting the mixture of T cells and a surface (e.g., particles such as beads), interactions between the particles and the cells can be minimized. This selects for cells that express high amounts of the desired antigen bound to the particles. For example, CD4+ T cells express higher levels of CD28 and are captured more efficiently than CD8+ T cells at dilute concentrations. In some embodiments, the concentration of cells used is 5 x 10^6 / ml. In other embodiments, the concentration used is between about 1 x 10^5 / ml and 1 x 10^6 / ml, and any integer value therebetween.
[0273] In some embodiments, cells are incubated on a rotator at various speeds for various times at either 2-10° C. or room temperature.
[0274] The stimulated T cells can also be frozen after the washing step. Without wishing to be bound by theory, the freezing and subsequent thawing step removes granulocytes and, to some extent, monocytes from the cell population, thereby providing a more uniform product. After the washing step, which removes plasma and platelets, the cells can be suspended in a freezing solution. While many freezing solutions and parameters are known in the art and are useful in this context, one method involves using PBS containing 20% DMSO and 8% human serum albumin, or culture medium containing 10% dextran 40 and 5% dextrose, 20% human serum albumin, and 7.5% DMSO, or culture medium containing 31.25% Plasmalyte-A, 31.25% dextrose 5%, 0.45% NaCl, 10% dextran 40 and 5% dextrose, 20% human serum albumin, and 7.5% DMSO, or other suitable cell freezing medium containing, for example, Hespan and PlasmaLyte A, followed by freezing the cells to -80°C at a rate of 10 / min and storing them in the vapor phase of a liquid nitrogen storage tank. Other methods of controlled freezing, as well as uncontrolled freezing at -20°C immediately or in liquid nitrogen, can be used.
[0275] In some embodiments, cryopreserved cells are thawed and washed as described herein and allowed to stand at room temperature for 1 hour before activation using the methods of the present disclosure.
[0276] In the context of the present disclosure, collection of a blood sample or apheresis product from a subject at a time before expanded cells as described herein may be needed is also contemplated. Thus, a source of expanded cells can be collected at any time needed, and desired cells, such as T cells, can be isolated and frozen for later use in immune effector cell therapy for any number of diseases or conditions that would benefit from immune effector cell therapy, such as those described herein. In one embodiment, a blood sample or apheresis is generally collected from a healthy subject. Optionally, a blood sample or apheresis is collected from a generally healthy subject who is at risk of developing a disease but has not yet developed the disease, and the desired cells are isolated and frozen for later use. Optionally, T cells can be expanded, frozen, and used at a later time. Optionally, a sample is collected from a patient shortly after diagnosis of a particular disease described herein, but before any treatment. In further embodiments, the cells are isolated from a blood sample or apheresis from the subject prior to any number of relevant treatment modalities, including treatment with drugs such as natalizumab, efalizumab, antivirals, chemotherapy, radiation, immunosuppressants such as cyclosporine, azathioprine, methotrexate, mycophenolic acid, and FK506, antibodies, or other immunoablative agents such as CAMPATH, anti-CD3 antibodies, cyclophosphamide, fludarabine, cyclosporine, FK506, rapamycin, mycophenolic acid, steroids, FR901228, and irradiation.
[0277] In further embodiments of the present disclosure, T cells are obtained from a patient immediately after treatment that leaves the subject with functional T cells. In some cases, following certain cancer treatments, particularly treatment with drugs that damage the immune system, the quality of the T cells obtained may be optimal or improved for their ability to expand ex vivo immediately after treatment during the period when the patient is typically recovering from the treatment. Similarly, after ex vivo manipulation using the methods described herein, these cells may be in a favorable state for enhanced engraftment and in vivo expansion. Thus, within the context of the present disclosure, it is contemplated to harvest blood cells, including T cells, dendritic cells, or other cells of the hematopoietic lineage, during this recovery period. Furthermore, in certain embodiments, mobilization (e.g., mobilization with GM-CSF) and conditioning regimens can be used to create conditions in the subject that favor the repopulation, recirculation, regeneration, and / or proliferation of specific cell types, particularly during a defined time frame following treatment. Exemplary cell types include T cells, B cells, dendritic cells, and other cells of the immune system.
[0278] In some embodiments, immune effector cells expressing a CAR molecule, e.g., CAR19 co-expressed with a cytokine-anchor, can be obtained from a subject that has received a low, immune-enhancing dose of an mTOR inhibitor. In some embodiments, a population of immune effector cells, e.g., T cells or NK cells, that express or are engineered to express a CAR, e.g., CAR19 co-expressed with a cytokine-anchor, can be treated ex vivo by contact with an amount of an mTOR inhibitor that increases the number of PD1-negative immune effector cells, e.g., T cells, or increases the ratio of PD1-negative immune effector cells, e.g., T cells / NK cells / PD1-positive immune effector cells, e.g., T cells or NK cells.
[0279] In some embodiments, the T cell population is deficient in diglycerol kinase (DGK).DGK-deficient cells include cells that do not express DGK RNA or protein, or that have reduced or inhibited DGK activity.DGK-deficient cells can be generated by genetic approaches, for example, by administering RNA interference agents, such as siRNA, shRNA, miRNA, to reduce or prevent DGK expression.Alternatively, DGK-deficient cells can be generated by treatment with DGK inhibitors as described herein.
[0280] In some embodiments, the T cell population is Ikaros-deficient.Ikaros-deficient cells include cells that do not express Ikaros RNA or protein, or that have reduced or inhibited Ikaros activity, and Ikaros-deficient cells can be generated by genetic approaches, for example, by administering RNA interference agents, such as siRNA, shRNA, miRNA, to reduce or prevent Ikaros expression.Alternatively, Ikaros-deficient cells can be generated by treatment with Ikaros inhibitors, such as lenalidomide.
[0281] In some embodiments, the T cell population is DGK-deficient and Ikaros-deficient, e.g., does not express DGK and Ikaros, or has reduced or inhibited DGK and Ikaros activity. Such DGK-deficient and Ikaros-deficient cells can be produced by any of the methods described herein.
[0282] In some embodiments, the NK cells are obtained from a subject. In another embodiment, the NK cells are an NK cell line, e.g., the NK-92 cell line (Conkwest).
[0283] Pharmaceutical Composition Provided herein are pharmaceutical compositions comprising nucleic acid molecules, cells, immune cells, or systems related to the cytokine-anchor disclosure.In this regard, the present disclosure provides pharmaceutical compositions comprising any of the cytokine-anchor materials described herein and a pharmaceutically acceptable excipient or carrier.In some embodiments, the pharmaceutical composition comprises the cells described herein, for example, engineered immune cells that express a CAR and cytokine-anchor, and a pharmaceutically acceptable excipient or carrier.

Suitable formulations can include any of the formulations for parenteral, subcutaneous, intravenous, intramuscular, intraarterial, intrathecal, intratumoral, or intraperitoneal administration. More than one route can be used to administer the IL-21 / 15 materials of the present invention, and in certain instances, a particular route can provide a more rapid and effective response than another route.
[0286] In some embodiments, one or more CAR-expressing cells disclosed herein can be administered or delivered to a subject via a biopolymer scaffold, e.g., a biopolymer implant. The biopolymer scaffold can support or enhance the delivery, proliferation, and / or dispersion of the CAR-expressing cells described herein. The biopolymer scaffold comprises a biodegradable polymer that is biocompatible (e.g., does not substantially induce an inflammatory or immune response) and / or can be natural or synthetic.
[0287] Examples of suitable biopolymers include agar, agarose, alginate, alginate / calcium phosphate cement (CPC), β-galactosidase (β-GAL), (1,2,3,4,6-pentaacetyl α-D-galactose), cellulose, chitin, chitosan, collagen, elastin, gelatin, hyaluronic acid collagen, hydroxyapatite, poly(3-hydroxybutyrate-co-3-hydroxy-hexanoate) (PHBHHx), poly(lactide), poly(caprolactone) (PCL), poly(lactide-co-glycolide) (PLG), polyethylene oxide (PEO), poly(lactic-co-glycolic acid) (PLGA), polypropylene oxide (PPO), polyvinyl alcohol) (PVA), silk, soy protein, and soy protein isolate, in any concentration and in any ratio, alone or in combination with any other polymer composition.

The biopolymer scaffold can be an injectable, e.g., gel or semi-solid, or solid composition.
[0288] In some embodiments, cells expressing a CAR and a cytokine anchor described herein can be seeded onto a biopolymer scaffold before delivery to a subject. In embodiments, the biopolymer scaffold further comprises one or more additional therapeutic agents described herein (e.g., another CAR-expressing cell, an antibody, or a small molecule), or an agent that enhances the activity of the CAR-expressing cell, for example, an agent incorporated into or conjugated to the biopolymer of the scaffold. In embodiments, the biopolymer scaffold is, for example, injected into a tumor or surgically implanted into a tumor or tumor proximity sufficient to mediate an anti-tumor effect. Further examples of biopolymer compositions and methods for their delivery are described in Stephan et al., Nature Biotechnology, 2015, 33:97-101 and U.S. Patent Application Publication No. US20210015863A1, each of which is incorporated herein by reference in its entirety.
[0289] In some embodiments, the cells are administered by injection, e.g., intravenously. Suitable pharmaceutically acceptable carriers for cells for injection may include any isotonic carrier, such as, for example, saline (about 0.90% w / v NaCl in water, about 300 mOsm / L NaCl in water, or about 9.0 g NaCl per liter of water), NORMOSOL R electrolyte solution (Abbott, Chicago, IL), PLASMA-LYTE A (Baxter, Deerfield, IL), about 5% dextrose in water, or lactated Ringer's. In some embodiments, the pharmaceutically acceptable carrier is supplemented with human serum albumin.
[0290] In some embodiments, pharmaceutical compositions comprise a cell or a plurality of cells expressing CAR and cytokine-anchor as described herein, in combination with one or more pharmaceutically or physiologically acceptable carriers, diluents or excipients.Such compositions can comprise buffer solutions, such as neutral buffered saline, phosphate buffered saline, carbohydrates, such as glucose, mannose, sucrose, or dextran, mannitol, proteins, polypeptides or amino acids, such as glycine, antioxidants, chelating agents, such as EDTA or glutathione, adjuvants (e.g., aluminum hydroxide), and preservatives.In one embodiment, the compositions of the present disclosure are formulated for intravenous administration.
[0291] The pharmaceutical composition of the present disclosure can be administered in a manner appropriate to the disease to be treated (or prevented). The amount and frequency of administration are determined by factors such as the patient's condition and the type and severity of the patient's disease, but the appropriate dosage can be determined by clinical trials.
[0292] In some embodiments, the pharmaceutical composition is substantially free of, e.g., completely free of, detectable levels of contaminants selected from the group consisting of endotoxin, mycoplasma, replication-competent lentivirus (RCL), p24, VSV-G nucleic acid, HIV gag, residual anti-CD3 / anti-CD28 coated beads, mouse antibodies, pooled human serum, bovine serum albumin, bovine serum, culture medium components, vector packaging cells or plasmid components, bacteria, and fungi.
