PCT Application Attorney Docket No.: FATE-173 / 01WO SOLID TUMOR TARGETING BACKBONE PROMOTING EFFECTOR CELL DIFFERENTIATION AND FUNCTION RELATED APPLICATION

[0001] The present application claims priority to U.S. Provisional Application Serial No. 63 / 517,343, filed August 2, 2023, the disclosure of which is hereby incorporated by reference in its entirety. INCORPORATION BY REFERENCE OF SEQUENCE LISTING

[0002] The Sequence Listing titled 184143-653101_SL.xml, which was created on August 2, 2023 and is 184,114 bytes in size, is hereby incorporated by reference in its entirety. FIELD OF THE INVENTION

[0003] The present disclosure is broadly concerned with the field of off-the-shelf immunocellular products. More particularly, the present disclosure is concerned with strategies for developing multifunctional effector cells capable of delivering therapeutically relevant properties in vivo. Cell products developed under the present disclosure address critical limitations of patient-sourced cell therapies. BACKGROUND OF THE INVENTION

[0004] The field of adoptive cell therapy is currently focused on using patient- and donor- sourced cells, which makes it particularly difficult to achieve consistent manufacturing of cancer immunotherapies and to deliver therapies to all patients who may benefit therefrom. There is also a need to improve the efficacy and persistence of adoptively transferred lymphocytes to promote favorable patient outcomes. Lymphocytes such as T cells and natural killer (NK) cells are potent anti-tumor effectors that play an important role in innate and adaptive immunity. However, the use of these immune cells for adoptive cell therapies remains challenging and has unmet needs for improvement. Therefore, there remain significant opportunities to harness the full potential of T and NK cells, or other immune effector cells in adoptive immunotherapy. SUMMARY OF THE INVENTION

[0005] There is a need for functionally improved effector cells that address issues ranging from response rate, cell exhaustion, loss of transfused cells (survival and / or persistence), tumorAttorney Docket No.: FATE-173 / 01WO escape through target loss or lineage switch, tumor targeting precision, off-target toxicity, off- tumor effect, to efficacy against solid tumors, i.e., tumor microenvironment and related immune suppression, recruiting, trafficking and infiltration.

[0006] It is an object of embodiments of the present invention to provide methods and compositions to generate derivative non-pluripotent cells differentiated from a single cell derived iPSC (induced pluripotent stem cell) clonal line, which iPSC line comprises one or several genetic modifications in its genome. In some embodiments, the one or several genetic modifications include one or more of DNA insertion, deletion, and substitution, and which modifications are retained and remain functional in subsequently derived cells after differentiation, expansion, passaging and / or transplantation.

[0007] The iPSC derived non-pluripotent cells of the present application include, but are not limited to, CD34+cells, hemogenic endothelium cells, HSCs (hematopoietic stem and progenitor cells), hematopoietic multipotent progenitor cells, T cell progenitors, NK cell progenitors, T cells, NKT cells, NK cells, and B cells. The iPSC-derived non-pluripotent cells of the present application comprise one or several genetic modifications in their genome through differentiation from an iPSC comprising the same genetic modifications. In some embodiments, the engineered clonal iPSC differentiation strategy for obtaining genetically engineered derivative cells benefits from the developmental potential of the iPSC in a directed differentiation that is not significantly adversely impacted by the engineered modality in the iPSC, and also that the engineered modality functions as intended in the derivative cell. Further, this strategy overcomes the present barrier in engineering primary lymphocytes, such as T cells or NK cells obtained from peripheral blood, as such cells are difficult to engineer, with engineering of such cells often lacking reproducibility and uniformity, resulting in cells exhibiting poor cell persistence with high cell death and low cell expansion. Moreover, this strategy avoids production of a heterogenous effector cell population otherwise obtained using primary cell sources which are heterogenous to start with.

[0051] Genomic modification of iPSCs (induced pluripotent stem cells) can include one or more of polynucleotide insertion, deletion, and substitution. Exogenous gene expression in genome-engineered iPSCs often encounters problems such as gene silencing or reduced gene expression after prolonged clonal expansion of the original genome-engineered iPSCs, after cell differentiation, and in dedifferentiated cell types from the cells derived from the genome- engineered iPSCs. On the other hand, direct engineering of primary immune cells such as T or NK cells is challenging and presents a hurdle to the preparation and delivery of engineered immune cells for adoptive cell therapy. In various embodiments, the present invention provides an efficient, reliable, and targeted approach for stably integrating one or more exogenous genes, including suicide genes and other functional modalities, which provide improved therapeutic properties relating to engraftment, trafficking, homing, migration, cytotoxicity, viability, maintenance, expansion, longevity, self-renewal, persistence, and / or survival, into iPSC derivative cells, including but not limited to HSCs (hematopoietic stem and progenitor cells), T cell progenitor cells, NK cell progenitor cells, T lineage cells, NKT lineage cells, and NK lineage cells.

[0053] Unless otherwise defined herein, scientific and technical terms used in connection with the present application shall have the meanings that are commonly understood by those of ordinary skill in the art. Further, unless otherwise required by context, singular terms shall include pluralities and plural terms shall include the singular.Attorney Docket No.: FATE-173 / 01WO

[0054] It should be understood that this invention is not limited to the particular methodology, protocols, and reagents, etc., described herein and as such may vary. The terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention, which is defined solely by the claims.

[0055] As used herein, the articles “a,” “an,” and “the” are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article. By way of example, “an element” means one element or more than one element.

[0056] The use of the alternative (e.g., “or”) should be understood to mean either one, both, or any combination thereof of the alternatives.

[0057] The term “and / or” should be understood to mean either one, or both of the alternatives.

[0060] As used herein, the terms “substantially free of” and “essentially free of” are used interchangeably, and when used to describe a composition, such as a cell population or culture media, refer to a composition that is free of a specified substance or its source thereof, such as, 95% free, 96% free, 97% free, 98% free, 99% free of the specified substance or its source thereof, or is undetectable as measured by conventional means. The term “free of” or “essentially free of” a certain ingredient or substance in a composition also means that no such ingredient or substance is (1) included in the composition at any concentration, or (2) included in the composition at a functionally inert, low concentration. Similar meaning can be applied to theAttorney Docket No.: FATE-173 / 01WO term “absence of,” where referring to the absence of a particular substance or its source thereof of a composition.

[0061] Throughout this specification, unless the context requires otherwise, the words “comprise,” “comprises” and “comprising” will be understood to imply the inclusion of a stated step or element or group of steps or elements but not the exclusion of any other step or element or group of steps or elements. In particular embodiments, the terms “include,” “has,” “contains,” and “comprise” are used synonymously.

[0062] By “consisting of” is meant including, and limited to, whatever follows the phrase “consisting of.” Thus, the phrase “consisting of” indicates that the listed elements are required or mandatory, and that no other elements may be present.

[0063] By “consisting essentially of” is meant including any elements listed after the phrase, and limited to other elements that do not interfere with or contribute to the activity or action specified in the disclosure for the listed elements. Thus, the phrase “consisting essentially of” indicates that the listed elements are required or mandatory, but that no other elements are optional and may or may not be present depending upon whether or not they affect the activity or action of the listed elements.

Thus, the appearances of the foregoing phrases in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0065] The term “ex vivo” refers generally to activities that take place outside an organism, such as experimentation or measurements done in or on living tissue in an artificial environment outside the organism, preferably with minimum alteration of the natural conditions. In particular embodiments, “ex vivo” procedures involve living cells or tissues taken from an organism and cultured in a laboratory apparatus, usually under sterile conditions, and typically for a few hours or up to about 24 hours, but including up to 48 or 72 hours or longer, depending on the circumstances. In certain embodiments, such tissues or cells can be collected and frozen, and later thawed for ex vivo treatment. Tissue culture experiments or procedures lasting longer than a few days using living cells or tissue are typically considered to be “in vitro,” though in certain embodiments, this term can be used interchangeably with ex vivo.

[0066] The term “in vivo” refers generally to activities that take place inside an organism.Attorney Docket No.: FATE-173 / 01WO

[0067] As used herein, the terms “reprogramming” or “dedifferentiation” or “increasing cell potency” or “increasing developmental potency” refer to a method of increasing the potency of a cell or dedifferentiating the cell to a less differentiated state. For example, a cell that has an increased cell potency has more developmental plasticity (i.e., can differentiate into more cell types) compared to the same cell in the non-reprogrammed state. In other words, a reprogrammed cell is one that is in a less differentiated state than the same cell in a non- reprogrammed state.

[0068] As used herein, the term “differentiation” is the process by which an unspecialized (“uncommitted”) or less specialized cell acquires the features of a specialized cell such as, for example, a blood cell or a muscle cell. A differentiated or differentiation- induced cell is one that has taken on a more specialized (“committed”) position within the lineage of a cell. The term “committed”, when applied to the process of differentiation, refers to a cell that has proceeded in the differentiation pathway to a point where, under normal circumstances, it will continue to differentiate into a specific cell type or subset of cell types, and cannot, under normal circumstances, differentiate into a different cell type or revert to a less differentiated cell type. As used herein, the term “pluripotent” refers to the ability of a cell to form all lineages of the body or soma (i.e., the embryo proper). For example, embryonic stem cells are a type of pluripotent stem cells that are able to form cells from each of the three germs layers, the ectoderm, the mesoderm, and the endoderm. Pluripotency is a continuum of developmental potencies ranging from the incompletely or partially pluripotent cell (e.g., an epiblast stem cell or EpiSC), which is unable to give rise to a complete organism to the more primitive, more pluripotent cell, which is able to give rise to a complete organism (e.g., an embryonic stem cell).

[0069] As used herein, the term “induced pluripotent stem cells” or “iPSCs”, refers to stem cells that are produced in vitro from differentiated adult, neonatal or fetal cells that have been induced or changed, i.e., reprogrammed into cells capable of differentiating into tissues of all three germ or dermal layers: mesoderm, endoderm, and ectoderm. In some embodiments, the reprogramming process uses reprogramming factors and / or small molecule chemical driven methods. The iPSCs produced do not refer to cells as they are found in nature.

[0070] As used herein, the term “embryonic stem cell” refers to naturally occurring pluripotent stem cells of the inner cell mass of the embryonic blastocyst. Embryonic stem cells are pluripotent and give rise during development to all derivatives of the three primary germ layers: ectoderm, endoderm and mesoderm. They do not contribute to the extra-embryonic membranes or the placenta (i.e., are not totipotent).

[0071] As used herein, the term “multipotent stem cell” refers to a cell that has the developmental potential to differentiate into cells of one or more germ layers (i.e., ectoderm,Attorney Docket No.: FATE-173 / 01WO mesoderm and endoderm), but not all three. Thus, a multipotent cell can also be termed a “partially differentiated cell.” Multipotent cells are known in the art, and examples of multipotent cells include adult stem cells, such as for example, hematopoietic stem cells and neural stem cells. “Multipotent” indicates that a cell may form many types of cells in a given lineage, but not cells of other lineages. For example, a multipotent hematopoietic cell can form the many different types of blood cells (red, white, platelets, etc.), but it cannot form neurons. Accordingly, the term “multipotency” refers to the state of a cell with a degree of developmental potential that is less than totipotent and pluripotent.

[0072] Pluripotency can be determined, in part, by assessing pluripotency characteristics of the cells. Pluripotency characteristics include, but are not limited to: (i) pluripotent stem cell morphology; (ii) the potential for unlimited self-renewal; (iii) expression of pluripotent stem cell markers including, but not limited to SSEA1 (mouse only), SSEA3 / 4, SSEA5, TRA1-60 / 81, TRA1-85, TRA2-54, GCTM-2, TG343, TG30, CD9, CD29, CD133 / prominin, CD140a, CD56, CD73, CD90, CD105, OCT4, NANOG, SOX2, CD30 and / or CD50; (iv) the ability to differentiate to all three somatic lineages (ectoderm, mesoderm and endoderm); (v) teratoma formation consisting of the three somatic lineages; and (vi) formation of embryoid bodies consisting of cells from the three somatic lineages.

[0073] Two types of pluripotency have previously been described: the “primed” or “metastable” state of pluripotency akin to the epiblast stem cells (EpiSC) of the late blastocyst, and the “naïve” or “ground” state of pluripotency akin to the inner cell mass of the early / preimplantation blastocyst. While both pluripotent states exhibit the characteristics as described above, the naïve or ground state further exhibits: (i) pre-inactivation or reactivation of the X-chromosome in female cells; (ii) improved clonality and survival during single-cell culturing; (iii) global reduction in DNA methylation; (iv) reduction of H3K27me3 repressive chromatin mark deposition on developmental regulatory gene promoters; and (v) reduced expression of differentiation markers relative to primed state pluripotent cells. Standard methodologies of cellular reprogramming in which exogenous pluripotency genes are introduced to a somatic cell, expressed, and then either silenced or removed from the resulting pluripotent cells are generally seen to have characteristics of the primed state of pluripotency. Under standard pluripotent cell culture conditions such cells remain in the primed state unless the exogenous transgene expression is maintained, wherein characteristics of the ground state are observed.

[0074] As used herein, the term “pluripotent stem cell morphology” refers to the classical morphological features of an embryonic stem cell. Normal embryonic stem cell morphology isAttorney Docket No.: FATE-173 / 01WO characterized by being round and small in shape, with a high nucleus-to-cytoplasm ratio, the notable presence of nucleoli, and typical inter-cell spacing.

[0075] As used herein, the term “subject” refers to any animal, preferably a human patient, livestock, or other domesticated animal.

[0076] A “pluripotency factor,” or “reprogramming factor,” refers to an agent capable of increasing the developmental potency of a cell, either alone or in combination with other agents. Pluripotency factors include, without limitation, polynucleotides, polypeptides, and small molecules capable of increasing the developmental potency of a cell. Exemplary pluripotency factors include, for example, transcription factors and small molecule reprogramming agents.

[0077] “Culture” or “cell culture” refers to the maintenance, growth and / or differentiation of cells in an in vitro environment. “Cell culture media,” “culture media” (singular “medium” in each case), “supplement” and “media supplement” refer to nutritive compositions that cultivate cell cultures.

[0078] “Cultivate” or “maintain” refers to the sustaining, propagating (growing) and / or differentiating of cells outside of tissue or the body, for example in a sterile plastic (or coated plastic) cell culture dish or flask. “Cultivation” or “maintaining” may utilize a culture medium as a source of nutrients, hormones and / or other factors helpful to propagate and / or sustain the cells.

[0079] As used herein, the term “mesoderm” refers to one of the three germinal layers that appears during early embryogenesis and which gives rise to various specialized cell types including blood cells of the circulatory system, muscles, the heart, the dermis, skeleton, and other supportive and connective tissues.

[0080] As used herein, the term “definitive hemogenic endothelium” (HE) or “pluripotent stem cell-derived definitive hemogenic endothelium” (iHE) refers to a subset of endothelial cells that give rise to hematopoietic stem and progenitor cells in a process called endothelial-to- hematopoietic transition. The development of hematopoietic cells in the embryo proceeds sequentially from lateral plate mesoderm through the hemangioblast to the definitive hemogenic endothelium and hematopoietic progenitors.

[0081] The term “hematopoietic stem and progenitor cells,” “hematopoietic stem cells,” “hematopoietic progenitor cells,” or “hematopoietic precursor cells” refers to cells which are committed to a hematopoietic lineage but are capable of further hematopoietic differentiation and include, multipotent hematopoietic stem cells (hematoblasts), myeloid progenitors, megakaryocyte progenitors, erythrocyte progenitors, and lymphoid progenitors. Hematopoietic stem and progenitor cells (HSCs) are multipotent stem cells that give rise to all the blood cell types including myeloid (monocytes and macrophages, neutrophils, basophils, eosinophils, erythrocytes, megakaryocytes / platelets, dendritic cells), and lymphoid lineages (T cells, B cells,Attorney Docket No.: FATE-173 / 01WO NK cells). The term “definitive hematopoietic stem cell” as used herein, refers to CD34+hematopoietic cells capable of giving rise to both mature myeloid and lymphoid cell types including T lineage cells, NK lineage cells and B lineage cells. Hematopoietic cells also include various subsets of primitive hematopoietic cells that give rise to primitive erythrocytes, megakarocytes and macrophages.

[0082] As used herein, the terms “T lymphocyte” and “T cell” are used interchangeably and refer to a principal type of white blood cell that completes maturation in the thymus and that has various roles in the immune system, including the identification of specific foreign antigens in the body and the activation and deactivation of other immune cells in an MHC class I- restricted manner. A T cell can be any T cell, such as a cultured T cell, e.g., a primary T cell, or a T cell from a cultured T cell line, e.g., Jurkat, SupT1, etc., or a T cell obtained from a mammal. The T cell can be a CD3+cell. The T cell can be any type of T cell and can be of any developmental stage, including but not limited to, CD4+ / CD8+double positive T cells, CD4+helper T cells (e.g., Th1 and Th2 cells), CD8+T cells (e.g., cytotoxic T cells), peripheral blood mononuclear cells (PBMCs), peripheral blood leukocytes (PBLs), tumor infiltrating lymphocytes (TILs), memory T cells, naïve T cells, regulator T cells, gamma delta T cells (γδ T cells), and the like. Additional types of helper T cells include cells such as Th3 (Treg), Th17, Th9, or Tfh cells. Additional types of memory T cells include cells such as central memory T cells (Tcm cells), effector memory T cells (Tem cells and TEMRA cells). The term “T cell” can also refer to a genetically engineered T cell, such as a T cell modified to express a T cell receptor (TCR) or a chimeric antigen receptor (CAR). A T cell or T cell like effector cell can also be differentiated from a stem cell or progenitor cell (“a derived T cell” or “a derived T cell like effector cell”, or collectively, “a derivative T lineage cell”). A derived T cell like effector cell may have a T cell lineage in some respects, but at the same time has one or more functional features that are not present in a primary T cell. In this application, a T cell, a T cell like effector cell, a derived T cell, a derived T cell like effector cell, or a derivative T lineage cell, are collectively termed as “a T lineage cell”.

[0083] “CD4+T cells” refers to a subset of T cells that express CD4 on their surface and are associated with cell-mediated immune response. They are characterized by secretion profiles following stimulation, which may include secretion of cytokines such as IFN-gamma, TNF- alpha, IL2, IL4 and IL10. “CD4” molecules are 55-kD glycoproteins originally defined as differentiation antigens on T-lymphocytes, but also found on other cells including monocytes / macrophages. CD4 antigens are members of the immunoglobulin supergene family and are implicated as associative recognition elements in MHC (major histocompatibilityAttorney Docket No.: FATE-173 / 01WO complex) class II-restricted immune responses. On T-lymphocytes they define the helper / inducer subset.

[0084] “CD8+T cells” refers to a subset of T cells which express CD8 on their surface, are MHC class I-restricted, and function as cytotoxic T cells. “CD8” molecules are differentiation antigens found on thymocytes and on cytotoxic and suppressor T-lymphocytes. CD8 antigens are members of the immunoglobulin supergene family and are associative recognition elements in major histocompatibility complex class I-restricted interactions.

[0085] As used herein, the term “NK cell” or “Natural Killer cell” refer to a subset of peripheral blood lymphocytes defined by the expression of CD56 or CD16 and the absence of the T cell receptor (CD3). An NK cell can be any NK cell, such as a cultured NK cell, e.g., a primary NK cell, or an NK cell from a cultured or expanded NK cell or a cell-line NK cell, e.g., NK-92, or an NK cell obtained from a mammal that is healthy or with a disease condition. As used herein, the terms “adaptive NK cell” and “memory NK cell” are interchangeable and refer to a subset of NK cells that are phenotypically CD3- and CD56+, expressing at least one of NKG2C and CD57, and optionally, CD16, but lack expression of one or more of the following: PLZF, SYK, FceRɣ, and EAT-2. In some embodiments, isolated subpopulations of CD56+NK cells comprise expression of CD16, NKG2C, CD57, NKG2D, NCR ligands, NKp30, NKp40, NKp46, activating and inhibitory KIRs, NKG2A and / or DNAM-1. CD56+can be dim or bright expression. An NK cell, or an NK cell like effector cell may be differentiated from a stem cell or progenitor cell (“a derived NK cell” or “a derived NK cell like effector cell”, or collectively, “a derivative NK lineage cell”). A derivative NK cell like effector cell may have an NK cell lineage in some respects, but at the same time has one or more functional features that are not present in a primary NK cell. In this application, an NK cell, an NK cell like effector cell, a derived NK cell, a derived NK cell like effector cell, or a derivative NK lineage cell, are collectively termed as “an NK lineage cell”.

[0086] As used herein, the term “NKT cells” or “natural killer T cells” or “NKT lineage cells” refers to CD1d-restricted T cells, which express a T cell receptor (TCR). Unlike conventional T cells that detect peptide antigens presented by conventional major histocompatibility (MHC) molecules, NKT cells recognize lipid antigens presented by CD1d, a non-classical MHC molecule. Two types of NKT cells are recognized. Invariant or type I NKT cells express a very limited TCR repertoire - a canonical α-chain (Vα24-Jα18 in humans) associated with a limited spectrum of β chains (Vβ11 in humans). The second population of NKT cells, called non-classical or non-invariant type II NKT cells, display a more heterogeneous TCR αβ usage. Type I NKT cells are considered suitable for immunotherapy. Adaptive or invariantAttorney Docket No.: FATE-173 / 01WO (type I) NKT cells can be identified by the expression of one or more of the following markers: TCR Va24-Ja18, Vb11, CD1d, CD3, CD4, CD8, aGalCer, CD161 and CD56.

[0087] The term “effector cell” generally is applied to certain cells in the immune system that carry out a specific activity in response to stimulation and / or activation, or to cells that effect a specific function upon activation. As used herein, the term “effector cell” includes, and in some contexts is interchangeable with, immune cells, “differentiated immune cells,” and primary or differentiated cells that are edited and / or modulated to carry out a specific activity in response to stimulation and / or activation. Non-limiting examples of effector cells include primary- sourced or iPSC-derived T cells, NK cells, NKT cells, B cells, macrophages, and neutrophils.

[0088] As used herein, the term “isolated” or the like refers to a cell, or a population of cells, which has been separated from its original environment, i.e., the environment of the isolated cells is substantially free of at least one component as found in the environment in which the “un-isolated” reference cells exist. The term includes a cell that is removed from some or all components as it is found in its natural environment, for example, isolated from a tissue or biopsy sample. The term also includes a cell that is removed from at least one, some or all components as the cell is found in non-naturally occurring environments, for example, isolated form a cell culture or cell suspension. Therefore, an “isolated cell” is partly or completely separated from at least one component, including other substances, cells or cell populations, as it is found in nature or as it is grown, stored or subsisted in non-naturally occurring environments. Specific examples of isolated cells include partially pure cell compositions, substantially pure cell compositions and cells cultured in a medium that is non-naturally occurring. Isolated cells may be obtained by separating the desired cells, or populations thereof, from other substances or cells in the environment, or by removing one or more other cell populations or subpopulations from the environment.

[0089] As used herein, the term “purify” or the like refers to increasing purity. For example, the purity can be increased to at least 50%, 60%, 70%, 80%, 90%, 95%, 99%, or 100%.

[0090] As used herein, the term “encoding” refers to the inherent property of specific sequences of nucleotides in a polynucleotide, such as a gene, a cDNA, or a mRNA, to serve as templates for synthesis of other polymers and macromolecules in biological processes having either a defined sequence of nucleotides (i.e., rRNA, tRNA and mRNA) or a defined sequence of amino acids and the biological properties resulting therefrom. Thus, a gene encodes a protein if transcription and translation of mRNA corresponding to that gene produces the protein in a cell or other biological system. Both the coding strand, the nucleotide sequence of which is identical to the mRNA sequence and is usually provided in sequence listings, and the non-coding strand,Attorney Docket No.: FATE-173 / 01WO used as the template for transcription of a gene or cDNA, can be referred to as “encoding” the protein or other product of that gene or cDNA.

[0091] A “construct” refers to a macromolecule or complex of molecules comprising a polynucleotide to be delivered to a host cell, either in vitro or in vivo. A “vector,” as used herein refers to any nucleic acid construct capable of directing the delivery or transfer of a foreign genetic material to target cells, where it can be replicated and / or expressed. Thus, the term “vector” comprises the construct to be delivered. A vector can be a linear or a circular molecule. A vector can be integrating or non-integrating. The major types of vectors include, but are not limited to, plasmids, episomal vectors, viral vectors, cosmids, and artificial chromosomes. Viral vectors include, but are not limited to, adenovirus vectors, adeno-associated virus vectors, retrovirus vectors, lentivirus vectors, Sendai virus vectors, and the like.

[0092] As used from time to time throughout the application, the expression of “TRAC_[construct]”, with “[construct]” being a variable expression construct having components and arrangement thereof specified in a given context, means that the expression construct is inserted at the TRAC locus to knock out TCR and with the component(s) of the expression construct expressed or co-expressed under the control of the endogenous TCR promoter.

[0093] As used from time to time throughout the application, the expression of “CD38_[construct]”, with “[construct]” being a variable expression construct having components and arrangement thereof specified in a given context, means that the expression construct is inserted at the CD38 locus to knock out CD38 and with the component(s) of the expression construct expressed or co-expressed, whether under control of the endogenous CD38 promoter or under an exogenous promoter in the construct.

[0094] By “integration” it is meant that one or more nucleotides of a construct is stably inserted into the cellular genome, i.e., covalently linked to the nucleic acid sequence within the cell’s chromosomal DNA. By “targeted integration” it is meant that the nucleotide(s) of a construct is inserted into the cell's chromosomal or mitochondrial DNA at a pre-selected site or “integration site”. The term “integration” as used herein further refers to a process involving insertion of one or more exogenous sequences or nucleotides of the construct, with or without deletion of an endogenous sequence or nucleotide at the integration site. In the case, where there is a deletion at the insertion site, “integration” may further comprise replacement of the endogenous sequence or a nucleotide that is deleted with the one or more inserted nucleotides.

[0095] As used herein, the term “exogenous” is intended to mean that the referenced molecule or the referenced activity is introduced into, or is non-native to, the host cell. The molecule can be introduced, for example, by introduction of an encoding nucleic acid into theAttorney Docket No.: FATE-173 / 01WO host genetic material such as by integration into a host chromosome or as non-chromosomal genetic material such as a plasmid. Therefore, the term as it is used in reference to expression of an encoding nucleic acid refers to introduction of the encoding nucleic acid in an expressible form into the cell. The term “endogenous” refers to a referenced molecule or activity that is present in the host cell. Similarly, the term when used in reference to expression of an encoding nucleic acid refers to expression of an encoding nucleic acid contained within the cell and not exogenously introduced.

[0096] As used herein, a “gene of interest” or “a polynucleotide sequence of interest” is a DNA sequence that is transcribed into RNA and in some instances translated into a polypeptide in vivo when placed under the control of appropriate regulatory sequences. A gene or polynucleotide of interest can include, but is not limited to, prokaryotic sequences, cDNA from eukaryotic mRNA, genomic DNA sequences from eukaryotic (e.g., mammalian) DNA, and synthetic DNA sequences. For example, a gene of interest may encode an miRNA, an shRNA, a native polypeptide (i.e., a polypeptide found in nature) or fragment thereof; a variant polypeptide (i.e., a mutant of the native polypeptide having less than 100% sequence identity with the native polypeptide) or fragment thereof; an engineered polypeptide or peptide fragment, a therapeutic peptide or polypeptide, an imaging marker, a selectable marker, and the like.

[0097] As used herein, the term “polynucleotide” refers to a polymeric form of nucleotides of any length, either deoxyribonucleotides or ribonucleotides or analogs thereof. The sequence of a polynucleotide is composed of four nucleotide bases: adenine (A); cytosine (C); guanine (G); thymine (T); and uracil (U) for thymine when the polynucleotide is RNA. A polynucleotide can include a gene or gene fragment (for example, a probe, primer, EST or SAGE tag), exons, introns, messenger RNA (mRNA), transfer RNA, ribosomal RNA, ribozymes, cDNA, recombinant polynucleotides, branched polynucleotides, plasmids, vectors, isolated DNA of any sequence, isolated RNA of any sequence, nucleic acid probes and primers. “Polynucleotide” also refers to both double- and single-stranded molecules.

[0098] As used herein, the terms “peptide,” “polypeptide,” and “protein” are used interchangeably and refer to a molecule having amino acid residues covalently linked by peptide bonds. A polypeptide must contain at least two amino acids, and no limitation is placed on the maximum number of amino acids of a polypeptide. As used herein, the terms refer to both short chains, which are also commonly referred to in the art as peptides, oligopeptides and oligomers, for example, and to longer chains, which generally are referred to in the art as polypeptides or proteins. “Polypeptides” include, for example, biologically active fragments, substantially homologous polypeptides, oligopeptides, homodimers, heterodimers, variants of polypeptides, modified polypeptides, derivatives, analogs, fusion proteins, among others. The polypeptidesAttorney Docket No.: FATE-173 / 01WO include natural polypeptides, recombinant polypeptides, synthetic polypeptides, or a combination thereof.

[0099] As used herein, the term “subunit” refers to each separate polypeptide chain of a protein complex, where each separate polypeptide chain can form a stable folded structure by itself. Many protein molecules are composed of more than one subunit, where the amino acid sequences can either be identical for each subunit, or similar, or completely different. For example, CD3 complex is composed of CD3α, CD3ε, CD3δ, CD3γ, and CD3ζ subunits, which form the CD3ε / CD3γ, CD3ε / CD3δ, and CD3ζ / CD3ζ dimers. Within a single subunit, contiguous portions of the polypeptide chain frequently fold into compact, local, semi-independent units that are called “domains”. Many protein domains may further comprise independent “structural subunits”, also called subdomains, contributing to a common function of the domain. As such, the term “subdomain” as used herein refers to a protein domain inside of a larger domain, for example, a binding domain within an ectodomain of a cell surface receptor; or a stimulatory domain or a signaling domain of an endodomain of a cell surface receptor. [000100] “Operably-linked” or “operatively linked,” interchangeable with “operably connected” or “operatively connected,” refers to the association of nucleic acid sequences on a single nucleic acid fragment (or amino acids in a polypeptide with multiple domains) so that the function of one is affected by the other. For example, a promoter is operably-linked with a coding sequence or functional RNA when it is capable of affecting the expression of that coding sequence or functional RNA (i.e., the coding sequence or functional RNA is under the transcriptional control of the promoter). Coding sequences can be operably-linked to regulatory sequences in sense or antisense orientation. As a further example, a receptor-binding domain can be operatively connected to an intracellular signaling domain, such that binding of the receptor to a ligand transduces a signal responsive to said binding. [000101] “Fusion proteins” or “chimeric proteins”, as used herein, are proteins created through genetic engineering to join two or more partial or whole polynucleotide coding sequences encoding separate proteins, and the expression of these joined polynucleotides results in a single peptide or multiple polypeptides with functional properties derived from each of the original proteins or fragments thereof. Between two neighboring polypeptides of different sources in the fusion protein, a linker (or spacer) peptide can be added. [000102] As used herein, the term “genetic imprint” refers to genetic or epigenetic information that contributes to preferential therapeutic attributes in a source cell or an iPSC, and is retainable in the source cell derived iPSCs, and / or the iPSC-derived hematopoietic lineage cells. As used herein, “a source cell” is a non-pluripotent cell that may be used for generating iPSCs through reprogramming, and the source cell derived iPSCs may be further differentiated toAttorney Docket No.: FATE-173 / 01WO specific cell types including any hematopoietic lineage cells. The source cell derived iPSCs, and differentiated cells therefrom are sometimes collectively called “derived” or “derivative” cells depending on the context. For example, derivative effector cells, or derivative NK cells or derivative T cells, as used throughout this application are cells differentiated from an iPSC, as compared to their primary counterpart obtained from natural / native sources such as peripheral blood, umbilical cord blood, or other donor tissues. As used herein, the genetic imprint(s) conferring a preferential therapeutic attribute is incorporated into the iPSCs either through reprogramming a selected source cell that is donor-, disease-, or treatment response- specific, or through introducing genetically modified modalities to iPSCs using genomic editing. In the aspect of a source cell obtained from a specifically selected donor, disease or treatment context, the genetic imprint contributing to preferential therapeutic attributes may include any context- specific genetic or epigenetic modifications which manifest a retainable phenotype, i.e., a preferential therapeutic attribute, that is passed on to derivative cells of the selected source cell, irrespective of the underlying molecular events being identified or not. Donor-, disease-, or treatment response- specific source cells may comprise genetic imprints that are retainable in iPSCs and derived hematopoietic lineage cells, which genetic imprints include but are not limited to, prearranged monospecific TCR, for example, from a viral specific T cell or invariant natural killer T (iNKT) cell; trackable and desirable genetic polymorphisms, for example, homozygous for a point mutation that encodes for the high-affinity CD16 receptor in selected donors; and predetermined HLA requirements, i.e., selected HLA-matched donor cells exhibiting a haplotype with increased population. As used herein, preferential therapeutic attributes include improved engraftment, trafficking, homing, viability, self-renewal, persistence, immune response regulation and modulation, survival, and cytotoxicity of a derived cell. A preferential therapeutic attribute may also relate to antigen targeting receptor expression; HLA presentation or lack thereof; resistance to tumor microenvironment; induction of bystander immune cells and immune modulations; improved on-target specificity with reduced off-tumor effect; and / or resistance to treatment such as chemotherapy. When derivative cells having one or more therapeutic attributes are obtained from differentiating an iPSC that has genetic imprint(s) conferring a preferential therapeutic attribute incorporated thereto, such derivative cells are also called “synthetic cells”. In general, a synthetic cell possesses one or more non-native cell functions when compared to its closest counterpart primary cell, whether the synthetic cell is differentiated from engineered pluripotent cells or obtained by engineering a primary cell from natural / native sources, such as peripheral blood, umbilical cord blood, or other donor tissues. For example, synthetic effector cells, or synthetic NK cells or synthetic T cells, as used throughout this application are cells differentiated from a genomically modified iPSC, as compared to their primary counterpartAttorney Docket No.: FATE-173 / 01WO obtained from natural / native sources such as peripheral blood, umbilical cord blood, or other donor tissues. In some embodiments, the synthetic cell possesses one or more non-native cell functions when compared to its closest counterpart primary cell. [000103] The term “enhanced therapeutic property” as used herein, refers to a therapeutic property of a cell that is enhanced as compared to a typical immune cell of the same general cell type. For example, an NK cell with an “enhanced therapeutic property” will possess an enhanced, improved, and / or augmented therapeutic property as compared to a typical, unmodified, and / or naturally occurring NK cell. Therapeutic properties of an immune cell may include, but are not limited to, cell engraftment, trafficking, homing, viability, self-renewal, persistence, immune response regulation and modulation, survival, and cytotoxicity. Therapeutic properties of an immune cell are also manifested by antigen targeting receptor expression; HLA presentation or lack thereof; resistance to tumor microenvironment; induction of bystander immune cells and immune modulations; improved on-target specificity with reduced off-tumor effect; and / or resistance to treatment such as chemotherapy. [000104] As used herein, the term “engager” refers to a molecule, e.g., a fusion polypeptide, which is capable of forming a link between an immune cell (e.g., a T cell, a NK cell, a NKT cell, a B cell, a macrophage, a neutrophil), and a tumor cell; and activating the immune cell. Examples of engagers include, but are not limited to, bi-specific T cell engagers (BiTEs), bi- specific killer cell engagers (BiKEs), tri-specific killer cell engagers (TriKEs), or multi-specific killer cell engagers, or universal engagers compatible with multiple immune cell types. [000105] As used herein, the term “surface triggering receptor” refers to a receptor capable of triggering or initiating an immune response, e.g., a cytotoxic response. Surface triggering receptors may be engineered, and may be expressed on effector cells, e.g., a T cell, a NK cell, a NKT cell, a B cell, a macrophage, or a neutrophil. In some embodiments, the surface triggering receptor facilitates bi- or multi- specific antibody engagement between the effector cells and a specific target cell (e.g., a tumor cell) independent of the effector cells’ natural receptors and cell types. Using this approach, one may generate iPSCs comprising a universal surface triggering receptor, and then differentiate such iPSCs into populations of various effector cell types that express the universal surface triggering receptor. By “universal”, it is meant that the surface triggering receptor can be expressed in, and activate, any effector cells irrespective of the cell type, and all effector cells expressing the universal receptor can be coupled or linked to the engagers recognizable by the surface triggering receptor, regardless of the engager’s tumor binding specificities. In some embodiments, engagers having the same tumor targeting specificity are used to couple with the universal surface triggering receptor. In some embodiments, engagers having different tumor targeting specificity are used to couple with theAttorney Docket No.: FATE-173 / 01WO universal surface triggering receptor. As such, one or multiple effector cell types can be engaged to kill one specific type of tumor cells in some cases, and to kill two or more types of tumors in other cases. A surface triggering receptor generally comprises a co-stimulatory domain for effector cell activation and an anti-epitope that is specific to the epitope of an engager. A bi- specific engager is specific to the anti-epitope of a surface triggering receptor on one end, and is specific to a tumor antigen on the other end. [000106] As used herein, the term “safety switch protein” refers to an engineered protein designed to prevent potential toxicity or otherwise adverse effects of a cell therapy. In some instances, the safety switch protein expression is conditionally controlled to address safety concerns for transplanted engineered cells that have permanently incorporated the gene encoding the safety switch protein into its genome. This conditional regulation could be variable and might include control through a small molecule-mediated post-translational activation and tissue- specific and / or temporal transcriptional regulation. The safety switch protein could mediate induction of apoptosis, inhibition of protein synthesis, DNA replication, growth arrest, transcriptional and post-transcriptional genetic regulation and / or antibody-mediated depletion. In some instance, the safety switch protein is activated by an exogenous molecule, e.g., a prodrug, that when activated, triggers apoptosis and / or cell death of a therapeutic cell. Examples of safety switch proteins include, but are not limited to, suicide genes such as caspase 9 (or caspase 3 or 7), thymidine kinase, cytosine deaminase, B cell CD20, modified EGFR, and any combination thereof. In this strategy, a prodrug that is administered in the event of an adverse event is activated by the suicide-gene product and kills the transduced cell. [000107] As used herein, the term “pharmaceutically active proteins or peptides” refers to proteins or peptides that are capable of achieving a biological and / or pharmaceutical effect on an organism. A pharmaceutically active protein has healing, curative or palliative properties against a disease and may be administered to ameliorate, relieve, alleviate, reverse or lessen the severity of a disease. A pharmaceutically active protein also has prophylactic properties and is used to prevent the onset of a disease or to lessen the severity of such disease or pathological condition when it does emerge. “Pharmaceutically active proteins” include an entire protein or peptide or pharmaceutically active fragments thereof. The term also includes pharmaceutically active analogs of the protein or peptide or analogs of fragments of the protein or peptide. The term pharmaceutically active protein also refers to a plurality of proteins or peptides that act cooperatively or synergistically to provide a therapeutic benefit. Examples of pharmaceutically active proteins or peptides include, but are not limited to, receptors, binding proteins, transcription and translation factors, tumor growth suppressing proteins, antibodies or fragments thereof, growth factors, and / or cytokines.Attorney Docket No.: FATE-173 / 01WO [000108] As used herein, the term “signaling molecule” refers to any molecule that modulates, participates in, inhibits, activates, reduces, or increases, cellular signal transduction. “Signal transduction” refers to the transmission of a molecular signal in the form of chemical modification by recruitment of protein complexes along a pathway that ultimately triggers a biochemical event in the cell. Examples of signal transduction pathways are known in the art, and include, but are not limited to, G protein coupled receptor signaling, tyrosine kinase receptor signaling, integrin signaling, toll gate signaling, ligand-gated ion channel signaling, ERK / MAPK signaling pathway, Wnt signaling pathway, cAMP-dependent pathway, and IP3 / DAG signaling pathway. [000109] As used herein, the term “targeting modality” refers to a molecule, e.g., a polypeptide, that is genetically incorporated into a cell to promote antigen and / or epitope specificity that includes, but is not limited to, i) antigen specificity as it relates to a unique chimeric antigen receptor (CAR) or T cell receptor (TCR), ii) engager specificity as it relates to monoclonal antibodies or bispecific engagers, iii) targeting of transformed cells, iv) targeting of cancer stem cells, and v) other targeting strategies in the absence of a specific antigen or surface molecule. [000110] As used herein, the term “specific” or “specificity” can be used to refer to the ability of a molecule, e.g., a receptor or an engager, to selectively bind to a target molecule, in contrast to non-specific or non-selective binding. [000111] The term “adoptive cell therapy” as used herein refers to a cell-based immunotherapy that relates to the transfusion of autologous or allogeneic lymphocytes, whether the immune cells are isolated from a human donor, or effector cells obtained from in vitro differentiation of a pluripotent cell; whether they are genetically modified or not; or whether they are primary donor cells or cells that have been passaged, expanded, or immortalized, ex vivo, after isolation from a donor. [000112] As used herein, “radiation” refers to the emission or transmission of energy in the form of waves or particles. Exemplary forms of radiation include, but are not limited to, electromagnetic radiation (e.g., radio waves, microwaves, infrared, visible light, ultraviolet, x- rays, and gamma radiation), particle radiation (e.g., alpha radiation, beta radiation, proton radiation and neutron radiation), and acoustic radiation (e.g., ultrasound, sound and seismic waves). In various embodiments, the amount of radiation is measured as a Gray (Gy), which is defined as the absorption of one joule of radiation energy per kilogram of matter. In radiation therapy, the amount of radiation applied varies depending on the type and stage of cancer being treated. For curative cases, the typical dose for a solid epithelial tumor ranges from 60 to 80 Gy, while lymphomas are typically treated with 20 to 40 Gy. Preventive (adjuvant) doses areAttorney Docket No.: FATE-173 / 01WO typically around 45–60 Gy in 1.8–2 Gy fractions (for, e.g., breast, head, and neck cancers). In various embodiments, radiation may be used as a sensitizing agent as disclosed herein. [000113] As used herein, “radiation therapy” or “radiotherapy” are used interchangeably to refer to a type of cancer treatment that involves use of radiation to damage cells by destroying the genetic material that controls how cells grow and divide. While both healthy and cancerous cells are damaged by radiation therapy, the goal of radiation therapy is to destroy as few normal, healthy cells as possible. The term “radiation therapy” often refers to external beam radiation therapy, wherein high-energy beams (e.g., x-rays, gamma rays, photons, protons, neutrons, ions, and any other forms of energy applicable to such treatments) are produced by a machine outside of the subject being treated, and are aimed at a precise point on the subject’s body. However, the term “radiation therapy” also includes brachytherapy, wherein seeds, ribbons, or capsules that contain or are otherwise linked to a radiation source are placed inside the subject’s body in or near a tumor or cancer cell. Included in brachytherapy are low-dose rate implants, high-dose rate implants, and permanent implants. Also included in the term “radiation therapy” is systemic radiation therapy, wherein radioactive drugs (e.g., radiopharmaceuticals or radionuclides, including radiopeptides) are given to the subject orally or intravenously and collect within the subject’s body at the tumor or area where cancers cells are located. Similar to antibody-drug candidates, where an antibody that binds to a tumor antigen is linked to a toxic drug, radiopharmaceuticals incorporate a radioactive compound linked to a targeting molecule (such as an antibody) that specifically binds to a tumor antigen. Examples of radioactive compounds useful in radiopharmaceuticals include, but are not limited to calcium-47, carbon-11, carbon-14, chromium-51, cobalt-57, cobalt-58, erbium-169, fluorine-18, gallium-67, gallium-68, hydrogen- 3, indium-111, iodine-123, iodine-125, iodine-131, iorn-59, krypton-81m, lutetium-177, nitrogen-13, oxygen-15, phosphorus-32, radium-223, rubidium-82, samarium-153, selenium-75, sodium-22, sodium-24, strontium-89, technetium-99m, thallium-201, xenon-133, and yttrium-90. In various embodiments, radiation therapy may be used as a sensitizing agent as disclosed herein. [000114] As used herein, “lymphodepletion” and “lympho-conditioning” are used interchangeably to refer to the destruction of lymphocytes and T cells, typically prior to immunotherapy. The purpose of lympho-conditioning prior to the administration of an adoptive cell therapy is to promote homeostatic proliferation of effector cells as well as to eliminate regulatory immune cells and other competing elements of the immune system that compete for homeostatic cytokines. Thus, lympho-conditioning is typically accomplished by administering one or more chemotherapeutic agents to the subject prior to a first dose of the adoptive cell therapy. In various embodiments, lympho-conditioning precedes the first dose of the adoptiveAttorney Docket No.: FATE-173 / 01WO cell therapy by a few hours to a few days. Exemplary chemotherapeutic agents useful for lympho-conditioning include, but are not limited to, cyclophosphamide (CY), fludarabine (FLU), and those described below. However, a sufficient lymphodepletion through anti-CD38 mAb could provide an alternative conditioning process for the present iNK cell therapy, without or with minimal need of a CY / FLU-based lympho-conditioning procedure, as further described herein. [000115] As used herein, “homing” or “trafficking” refers to active navigation (migration) of a cell to a target site (e.g., a cell, tissue (e.g., tumor), or organ). A “homing molecule” refers to a molecule that directs cells to a target site. In some embodiments, a homing molecule functions to recognize and / or initiate interaction of a cell to a target site. In some embodiments, a homing molecule is a chemokine receptor. As used herein, “chemokine receptor” refers to a cell surface molecule that binds to a chemokine. A chemokine receptor can comprise a naturally occurring or recombinant chemokine receptor or a variant thereof. Exemplary chemokine receptors include, but are not limited to, a CXC chemokine receptor (for example, CXCR1, CXCR2, CXCR3, CXCR4, CXCR5, CXCR6, or CXCR7), a CC chemokine receptor (for example, CCR1, CCR2, CCR3, CCR4, CCR5, CCR6, CCR7, CCR8, CCR9, CCR10, or CCR11), a CX3C chemokine receptor (for example, CX3CR1), an XC chemokine receptor (for example, XCR1), or a variant thereof. [000116] A “therapeutically sufficient amount”, as used herein, includes within its meaning a non-toxic, but sufficient and / or effective amount of a particular therapeutic agent and / or pharmaceutical composition to which it is referring to provide a desired therapeutic effect. The exact amount required will vary from subject to subject, depending on factors such as the patient’s general health, the patient’s age and the stage and severity of the condition being treated. In particular embodiments, a “therapeutically sufficient amount” is sufficient and / or effective to ameliorate, reduce, and / or improve at least one symptom associated with a disease or condition of the subject being treated. [000117] Differentiation of pluripotent stem cells requires a change in the culture system, such as changing the stimuli agents in the culture medium or the physical state of the cells. The most conventional strategy utilizes the formation of embryoid bodies (EBs) as a common and critical intermediate to initiate lineage-specific differentiation. “Embryoid bodies” are three- dimensional clusters that have been shown to mimic embryo development as they give rise to numerous lineages within their three-dimensional area. Through the differentiation process, typically a few hours to days, simple EBs (for example, aggregated pluripotent stem cells elicited to differentiate) continue maturation and develop into a cystic EB at which time, typically days to a few weeks, they are further processed to continue differentiation. EB formation is initiatedAttorney Docket No.: FATE-173 / 01WO by bringing pluripotent stem cells into close proximity with one another in three-dimensional multilayered clusters of cells. Typically, this is achieved by one of several methods including allowing pluripotent cells to sediment in liquid droplets, sedimenting cells into “U” bottomed well-plates or by mechanical agitation. To promote EB development, the pluripotent stem cell aggregates require further differentiation cues, as aggregates maintained in pluripotent culture maintenance medium do not form proper EBs. As such, the pluripotent stem cell aggregates need to be transferred to differentiation medium that provides eliciting cues towards the lineage of choice. EB-based culture of pluripotent stem cells typically results in generation of differentiated cell populations (i.e., ectoderm, mesoderm and endoderm germ layers) with modest proliferation within the EB cell cluster. Although proven to facilitate cell differentiation, EBs, however, give rise to heterogeneous cells in variable differentiation states because of the inconsistent exposure of the cells in the three-dimensional structure to the differentiation cues within the environment. In addition, EBs are laborious to create and maintain. Moreover, cell differentiation through EB formation is accompanied with modest cell expansion, which also contributes to low differentiation efficiency. [000118] In comparison, “aggregate formation,” as distinct from “EB formation,” can be used to expand the populations of pluripotent stem cell derived cells. For example, during aggregate-based pluripotent stem cell expansion, culture media are selected to maintain proliferation and pluripotency. Cell proliferation generally increases the size of the aggregates, forming larger aggregates, which can be mechanically or enzymatically dissociated into smaller aggregates to maintain cell proliferation within the culture and increase numbers of cells. As distinct from EB culture, cells cultured within aggregates in maintenance culture media maintain markers of pluripotency. The pluripotent stem cell aggregates require further differentiation cues to induce differentiation. [000119] As used herein, “monolayer differentiation” is a term referring to a differentiation method distinct from differentiation through three-dimensional multilayered clusters of cells, i.e., “EB formation.” Monolayer differentiation, among other advantages disclosed herein, avoids the need for EB formation to initiate differentiation. Because monolayer culturing does not mimic embryo development such as is the case with EB formation, differentiation towards specific lineages is deemed to be minimal as compared to all three germ layer differentiation in EB formation. [000120] As used herein, a “dissociated cell” or “single dissociated cell” refers to a cell that has been substantially separated or purified away from other cells or from a surface (e.g., a culture plate surface). For example, cells can be dissociated from an animal or tissue by mechanical or enzymatic methods. Alternatively, cells that aggregate in vitro can beAttorney Docket No.: FATE-173 / 01WO enzymatically or mechanically dissociated from each other, such as by dissociation into a suspension of clusters, single cells or a mixture of single cells and clusters. In yet another alternative embodiment, adherent cells can be dissociated from a culture plate or other surface. Dissociation thus can involve breaking cell interactions with extracellular matrix (ECM) and substrates (e.g., culture surfaces), or breaking the ECM between cells. [000121] As used herein, a “master cell bank” or “MCB” refers to a clonal master engineered iPSC line, which is a clonal population of iPSCs that have been engineered to comprise one or more therapeutic attributes, have been characterized, tested, qualified, and expanded, and have been shown to reliably serve as the starting cellular material for the production of cell-based therapeutics through directed differentiation in manufacturing settings. In various embodiments, an MCB is maintained, stored, and / or cryopreserved in multiple vessels to prevent genetic variation and / or potential contamination by reducing and / or eliminating the total number of times the iPS cell line is passaged, thawed or handled during the manufacturing processes. [000122] As used herein, “feeder cells” or “feeders” are terms describing cells of one type that are co-cultured with cells of a second type to provide an environment in which the cells of the second type can grow, expand, or differentiate, as the feeder cells provide stimulation, growth factors and nutrients for the support of the second cell type. The feeder cells are optionally from a different species as the cells they are supporting. For example, certain types of human cells, including stem cells, can be supported by primary cultures of mouse embryonic fibroblasts, or immortalized mouse embryonic fibroblasts. In another example, peripheral blood derived cells or transformed leukemia cells support the expansion and maturation of natural killer cells. The feeder cells may typically be inactivated when being co-cultured with other cells by irradiation or treatment with an anti-mitotic agent such as mitomycin to prevent them from outgrowing the cells they are supporting. Feeder cells may include endothelial cells, stromal cells (for example, epithelial cells or fibroblasts), and leukemic cells. Without limiting the foregoing, one specific feeder cell type may be a human feeder, such as a human skin fibroblast. Another feeder cell type may be mouse embryonic fibroblasts (MEF). In general, various feeder cells can be used in part to maintain pluripotency, direct differentiation towards a certain lineage, enhance proliferation capacity and promote maturation to a specialized cell type, such as an effector cell. [000123] As used herein, a “feeder-free” (FF) environment refers to an environment such as a culture condition, cell culture or culture media which is essentially free of feeder or stromal cells, and / or which has not been pre-conditioned by the cultivation of feeder cells. “Pre- conditioned” medium refers to a medium harvested after feeder cells have been cultivated within the medium for a period of time, such as for at least one day. Pre-conditioned medium contains many mediator substances, including growth factors and cytokines secreted by the feeder cellsAttorney Docket No.: FATE-173 / 01WO cultivated in the medium. In some embodiments, a feeder-free environment is free of both feeder or stromal cells and is also not pre-conditioned by the cultivation of feeder cells. [000124] “Functional” as used in the context of genomic editing or modification of iPSC, and derived non-pluripotent cells differentiated therefrom, or genomic editing or modification of non-pluripotent cells and derived iPSCs reprogrammed therefrom, refers to (1) at the gene level—successful knocked-in, knocked-out, knocked-down gene expression, transgenic or controlled gene expression such as inducible or temporal expression at a desired cell development stage, which is achieved through direct genomic editing or modification, or through “passing-on” via differentiation from or reprogramming of a starting cell that is initially genomically engineered; or (2) at the cell level—successful removal, addition, or alteration of a cell function / characteristic via (i) gene expression modification obtained in said cell through direct genomic editing, (ii) gene expression modification maintained in said cell through “passing-on” via differentiation from or reprogramming of a starting cell that is initially genomically engineered; (iii) down-stream gene regulation in said cell as a result of gene expression modification that only appears in an earlier development stage of said cell, or only appears in the starting cell that gives rise to said cell via differentiation or reprogramming; or (iv) enhanced or newly attained cellular function or attribute displayed within the mature cellular product, initially derived from the genomic editing or modification conducted at the iPSC, progenitor or dedifferentiated cellular origin. [000125] “HLA deficient”, including HLA class I deficient, HLA class II deficient, or both, refers to cells that either lack, or no longer maintain, or have a reduced level of surface expression of a complete MHC complex comprising an HLA class I protein heterodimer and / or an HLA class II heterodimer, such that the diminished or reduced level is less than the level naturally detectable by other cells or by synthetic methods. [000126] “Modified HLA deficient iPSC,” as used herein, refers to an HLA deficient iPSC that is further modified by introducing genes expressing proteins related, but not limited to improved differentiation potential, antigen targeting, antigen presentation, antibody recognition, persistence, immune evasion, resistance to suppression, proliferation, costimulation, cytokine stimulation, cytokine production (autocrine or paracrine), chemotaxis, and cellular cytotoxicity, such as non-classical HLA class I proteins (e.g., HLA-E and HLA-G), chimeric antigen receptor (CAR), T cell receptor (TCR), CD16 Fc Receptor, BCL11b, NOTCH, RUNX1, IL15, 4-1BB, DAP10, DAP12, CD24, CD3ζ, 4-1BBL, CD47, CD113, and PDL1. The cells that are “modified HLA deficient” also include cells other than iPSCs. [000127] The term “ligand” refers to a substance that forms a complex with a target molecule to produce a signal by binding to a site on the target. The ligand may be a natural or artificialAttorney Docket No.: FATE-173 / 01WO substance capable of specific binding to the target. The ligand may be in the form of a protein, a peptide, an antibody, an antibody complex, a conjugate, a nucleic acid, a lipid, a polysaccharide, a monosaccharide, a small molecule, a nanoparticle, an ion, a neurotransmitter, or any other molecular entity capable of specific binding to a target. The target to which the ligand binds, may be a protein, a nucleic acid, an antigen, a receptor, a protein complex, or a cell. A ligand that binds to and alters the function of the target and triggers a signaling response is called “agonistic” or “an agonist”. A ligand that binds to a target and blocks or reduces a signaling response is “antagonistic” or “an antagonist.” [000128] The term “antibody” is used herein in the broadest sense and refers generally to an immune-response generating molecule that contains at least one binding site that specifically binds to a target, wherein the target may be an antigen, or a receptor that is capable of interacting with certain antibodies. For example, an NK cell can be activated by the binding of an antibody or the Fc region of an antibody to its Fc-gamma receptors (FcγR), thereby triggering the ADCC (antibody-dependent cellular cytotoxicity) mediated effector cell activation. A specific piece or portion of an antigen or receptor, or a target in general, to which an antibody binds is known as an epitope or an antigenic determinant. The term “antibody” includes, but is not limited to, native antibodies and variants thereof, fragments of native antibodies and variants thereof, peptibodies and variants thereof, and antibody mimetics that mimic the structure and / or function of an antibody or a specified fragment or portion thereof, including single chain antibodies and fragments thereof. An antibody may be a murine antibody, a human antibody, a humanized antibody, a camel IgG, a single variable new antigen receptor (VNAR), a shark heavy-chain antibody (Ig-NAR), a chimeric antibody, a recombinant antibody, a single-domain antibody (dAb), an anti-idiotype antibody, a bi-specific-, multi-specific- or multimeric- antibody, or antibody fragment thereof. Anti-idiotype antibodies are specific for binding to an idiotope of another antibody, wherein the idiotope is an antigenic determinant of an antibody. A bi-specific antibody may be a BiTE (bi-specific T cell engager) or a BiKE (bi-specific killer cell engager), and a multi-specific antibody may be a TriKE (tri-specific Killer cell engager). Non-limiting examples of antibody fragments include Fab, Fab', F(ab')2, F(ab')3, Fv, Fabc, pFc, Fd, single chain fragment variable (scFv), tandem scFv (scFv)2, single chain Fab (scFab), disulfide stabilized Fv (dsFv), minibody, diabody, triabody, tetrabody, single-domain antigen binding fragments (sdAb), camelid heavy-chain IgG and Nanobody® fragments, recombinant heavy- chain-only antibody (VHH), and other antibody fragments that maintain the binding specificity of the antibody. [000129] “Fc receptors,” abbreviated FcR, are classified based on the type of antibody that they recognize. For example, those that bind the most common class of antibody, IgG, are calledAttorney Docket No.: FATE-173 / 01WO Fc-gamma receptors (FcγR), those that bind IgA are called Fc-alpha receptors (FcαR) and those that bind IgE are called Fc-epsilon receptors (FcεR). The classes of FcRs are also distinguished by the cells that express them (macrophages, granulocytes, natural killer cells, T and B cells) and the signaling properties of each receptor. Fc-gamma receptors (FcγR) include several members, FcγRI (CD64), FcγRIIA (CD32), FcγRIIB (CD32), FcγRIIIA (CD16a), and FcγRIIIB (CD16b), which differ in their antibody affinities due to their different molecular structures. [000130] “Chimeric Receptor” is a general term used to describe an engineered, artificial, or a hybrid receptor protein molecule that is made to comprise two or more portions of amino acid sequences that are originated from at least two different proteins. The chimeric receptor proteins have been engineered to give a cell the ability to initiate signal transduction and carry out downstream function upon binding of an agonistic ligand to the receptor. Exemplary “chimeric receptors” include, but are not limited to, chimeric antigen receptors (CARs), chimeric fusion receptors (CFRs), chimeric Fc receptors (CFcRs), as well as fusions of two or more receptors. [000131] “Chimeric Fc Receptor,” abbreviated as CFcR, is a term used to describe engineered Fc receptors having their native transmembrane and / or intracellular signaling domains modified or replaced with non-native transmembrane and / or intracellular signaling domains. In some embodiments of the chimeric Fc receptor, in addition to having one of, or both of, the transmembrane and signaling domains being non-native, one or more stimulatory domains can be introduced to the intracellular portion of the engineered Fc receptor to enhance cell activation, expansion and function upon triggering of the receptor. Unlike a chimeric antigen receptor (CAR), which contains an antigen binding domain to a target antigen, the chimeric Fc receptor binds to an Fc fragment, or the Fc region of an antibody, or the Fc region comprised in an engager or a binding molecule and activates the cell function with or without bringing the targeted cell close in vicinity. For example, a Fcγ receptor can be engineered to comprise selected transmembrane, stimulatory, and / or signaling domains in the intracellular region that respond to the binding of IgG at the extracellular domain, thereby generating a CFcR. In one example, a CFcR is produced by engineering CD16, a Fcγ receptor, by replacing its transmembrane domain and / or intracellular domain. To further improve the binding affinity of the CD16-based CFcR, the extracellular domain of CD64 or the high-affinity variants of CD16 (F176V, for example) can be incorporated. In some embodiments of the CFcR where a high affinity CD16 extracellular domain is involved, the proteolytic cleavage site comprising a serine at position 197 is eliminated or is replaced such at the extracellular domain of the receptor is non-cleavable, i.e., not subject to shedding, thereby obtaining a hnCD16-based CFcR. [000132] CD16, a FcγR receptor, has been identified to have two isoforms, Fc receptors FcγRIIIa (CD16a) and FcγRIIIb (CD16b). CD16a is a transmembrane protein expressed by NKAttorney Docket No.: FATE-173 / 01WO cells, which binds monomeric IgG attached to target cells to activate NK cells and facilitate antibody-dependent cell-mediated cytotoxicity (ADCC). “High affinity CD16,” “non-cleavable CD16,” or “high affinity non-cleavable CD16” (abbreviated as hnCD16), as used herein, refers to a natural or non-natural variant of CD16. The wildtype CD16 has low affinity and is subject to ectodomain shedding, a proteolytic cleavage process that regulates the cells surface density of various cell surface molecules on leukocytes upon NK cell activation. F176V and F158V are exemplary CD16 polymorphic variants having high affinity. A CD16 variant having the cleavage site (position 195-198) in the membrane-proximal region (position 189-212) altered or eliminated is not subject to shedding. The cleavage site and the membrane-proximal region are described in detail in WO2015 / 148926, the complete disclosure of which is incorporated herein by reference. The CD16 S197P variant is an engineered non-cleavable version of CD16. A CD16 variant comprising both F158V and S197P has high affinity and is non-cleavable. Another exemplary high affinity and non-cleavable CD16 (hnCD16) variant is an engineered CD16 comprising an ectodomain originated from one or more of the 3 exons of the CD64 ectodomain. [000133] In some embodiments, provided herein are cells comprising a set of engineered components that collectively complement (and in some cases synergize with) one another to enhance the activity of an effector cell, in the context of treating a tumor in general, and for a solid tumor microenvironment in particular. The selected set of engineered components are referred to herein as a “backbone;” for its compatibility with any tumor antigen binding molecule to be expressed in the effector cell, including but not limited to, a CAR, an antibody, a bispecific antibody, and a TCR. However, the term “backbone” does not require any particular physical relationship between the individual components of the set, or their location within the cell; although certain association and / or arrangements (e.g., order in a co-expression construct of two or more of the individual components) may be optimized for higher expression level or ease of processing, among other considerations in a manufacturing setting. For example, a backbone may comprise integration of two expression cassettes, each at a different location in the genome of the cell. In some embodiments, the backbone comprises a plurality of genomic modifications, such as the insertion of one or more polynucleotides and / or modification to knockout one or more genes. Modifications may be made simultaneously or sequentially. Non-limiting examples of effector cell function that may be increased by the modifications of the backbone include one or more of improving cell growth, proliferation, expansion, and / or effector function autonomously without contacting additionally supplied soluble cytokines in vitro or in vivo, as well as enhanced homing, trafficking, depletion or reduction of alloreactive host immune cells, and retention at tumor sites, in which the tumor cells could be sensitized to synergize with the functional features provided to the effector cells. A solid tumor targeting backbone of the presentAttorney Docket No.: FATE-173 / 01WO disclosure can be particularly beneficial in the context of an iPSC comprising the backbone, such as by providing a master cell bank providing a source of starting cells that can be modified by the simple addition of a tumor antigen binding molecule for an indication intended to be treated, and then being used as a source for differentiating enhanced effector cells with therapeutic properties for one or more intended tumor indications. I. Cells and Compositions Useful for Adoptive Cell Therapies with Enhanced Properties [000134] Provided herein is a strategy to systematically engineer the regulatory circuitry of a clonal iPSC without impacting the differentiation potency and cell development biology of the iPSC and its derivative cells, while enhancing the therapeutic properties of the derivative cells differentiated from the iPSC. The iPSC-derived cells are functionally improved and suitable for adoptive cell therapies following a combination of selective modalities being introduced to the cells at the level of iPSC through genomic engineering. It was previously unclear whether altered iPSCs comprising one or more provided genetic edits still have the capacity to enter cell development, and / or to mature and generate functional differentiated cells while retaining modified activities and / or properties. Unanticipated failures during directed cell differentiation from iPSCs have been attributed to aspects including, but not limited to, development stage specific gene expression or lack thereof, requirements for HLA complex presentation, protein shedding of introduced surface expressing modalities, and the need for reconfiguration of differentiation protocols enabling phenotypic and / or functional change in the cell. The present application has shown that the one or more selected genomic modifications as provided herein does not negatively impact iPSC differentiation potency, and the functional effector cells derived from the engineered iPSC have enhanced and / or acquired therapeutic properties attributable to the individual or combined genomic modifications retained in the effector cells following the iPSC differentiation. Further, all genomic modifications and combinations thereof as may be described in the context of iPSC and iPSC-derived effector cells are applicable to primary sourced cells, including primary immune cells such as T, NK, or immunregulatory cells, whether cultured or expanded, the modification of which results in engineered immune cells useful for adoptive cell therapy. [000135] Further, while CAR-T cells have been shown to be effective and potent in treating several hematologic malignancies, engineered T cell therapies have had limited success in addressing solid tumors. Unlike liquid tumors where uniformly-expressed antigens are accessible and can be effectively targeted, tumor access, lack of tumor-exclusive antigen targets, and antigen heterogeneity are significant barriers to the successful development of CAR-T cellsAttorney Docket No.: FATE-173 / 01WO in solid tumors. In addition, inherent genetic engineering variability seen with patient- and donor- derived immune cells limits the wide application of CAR-T cell therapy. The present application provides genomic engineering aspects in the form of a solid tumor targeting backbone, as well as other genetic modalities, to improve on-target specificity with reduced off- tumor effect in the off-the-shelf adoptive cell therapy setting using effector cells derived from engineered iPSCs, to evade allorejection, as well as to overcome suppressive tumor microenvironment, a heightened challenge especially with solid tumors. 1. C-X-C Motif Chemokine Receptor Overexpression [000136] Chemokines are a family of homogeneous serum proteins of about 7 to about 16 kDa originally characterized by their ability to induce leukocyte migration. Most of chemokines have four characteristic cysteines (Cys) and are classified into C-X-C (or alpha, CXC), C-C (or beta), C (or gamma), and CX3C (or delta) chemokine classes, according to motifs displayed by the first two cysteines. Subfamilies of C-X-C (or alpha, CXC) are further classified, according to the presence of an ELR motif (Glu-Leu-Arg) preceding the first cysteine, into two groups: ELR-CXC chemokines and non-ELR-CXC chemokines. [000137] CXC chemokine receptor 2 (CXCR2), also known as CD128, interleukin 8 receptor beta (IL8Rβ), or L8 receptor type B, is a chemokine receptor mostly expressed by neutrophils, mast cells, monocytes, and macrophages. It is known that CD56 dim NK cells express CXCR2, however its expression can be downregulated upon NK cell activation. T cells typically do not express CXCR2. iPSCs and iPSC-derived T cells do not express CXCR2 without transducing exogenous polynucleotides encoding CXCR2 as disclosed in this application. The chemokine IL8 (also known as CXCL8) is secreted by mononuclear macrophages, neutrophils, eosinophils, T lymphocytes, epithelial cells, and fibroblasts, and functions as a chemotactic factor by guiding the neutrophils to the site of infection. CXCL8 is also secreted by tumor cells and promotes tumor migration, invasion, angiogenesis and metastasis. CXCL8 is one of the ligands to multiple CXC chemokine receptors including CXCR1 and CXCR2. Additional chemokines known to bind to CXCR2 include, but are not limited to, CXCL1, GROβ (CXCL2), CXCL3, CXCL5, CXCL6, and CXCL7. [000138] CXC chemokine receptor 3 (CXCR3), also known as G Protein-coupled Receptor 9 (GPR9) and CD183, is a G Protein-coupled receptor that binds to the chemokines CXCL9, CXCL10, and CXCL11. CXCR3 is expressed primarily in activated T-helper type 1 (Th1) lymphocytes, but is also present in natural killer cells, macrophages, dendritic cells, and B lymphocyte subsets. The interaction of CXCR3 and its ligands is involved in guiding receptor-Attorney Docket No.: FATE-173 / 01WO bearing cells to specific parts of the body, especially sites of inflammation, immune impairment, and immune dysfunction. [000139] In various embodiments, the present application provides effector cells or iPSCs genetically engineered to comprise, among other editing as contemplated and described herein, a solid tumor targeting backbone comprising, among other genetic modalities, a C-X-C motif chemokine receptor. In various embodiments, the C-X-C motif chemokine receptor comprises CXCR2 or CXCR3, or variants thereof. A non-limiting example of the amino acid sequence of human CXCR2 is one registered as UniProtKB No: P25025. In one embodiment, the CXCR2 comprises an amino acid sequence of at least 75%, 80%, 85%, 90%, 95% or 99% identity to SEQ ID NO: 1. In some embodiments, the CXCR2 comprises an amino acid sequence of at least 90% identity to SEQ ID NO: 1. In some embodiments, the CXCR2 comprises an amino acid sequence of at least 95% identity to SEQ ID NO: 1. In some embodiments, the CXCR2 comprises the amino acid sequence of SEQ ID NO: 1. As used herein and throughout the application, the percent identity between two sequences is a function of the number of identical positions shared by the sequences (i.e., % identity = # of identical positions / total # of positions x 100), taking into account the number of gaps, and the length of each gap, which need to be introduced for optimal alignment of the two sequences. The comparison of sequences and determination of percent identity between two sequences can be accomplished using a mathematical algorithm recognized in the art.

In some embodiments, the selected locus for insertion of the C-X-C motif chemokine receptor comprises a safe harbor locus, a gene locus intended to be disrupted or knocked out, a gene locus that provides an endogenous promoter that provides spacial and / or temporal control of the exogenous gene expression. In some embodiments, the selected locus for C-X-C motif chemokine receptor insertion comprises AAVS1, CCR5, ROSA26, collagen, HTRP, H11, PH12, GAPDH, RUNX1, B2M, TAP1, TAP2, Tapasin, NLRC5, CIITA, RFXANK, RFX5, RFXAP, TCR, NKG2A, NKG2D, CD38, CD25, CD69, CD44, CD58, CD54, CD56, CD71, CIS, CBL-B, SOCS2, PD1, CTLA4, LAG3, TIM3, or TIGIT. In one embodiment, the selected locus for C-X-C motif chemokine receptor insertion is the TCR locus. In one embodiment, the selected locus for C-X-C motif chemokine receptor insertion is the CD38 locus. [000142] In some embodiments, the C-X-C motif chemokine receptor is co-expressed with one or more exogenous polynucleotides encoding a polypeptide of interest through separate expression constructs, or a single bi- or tri- cistronic expression cassete. In some embodiments, the single bi- or tri- cistronic expression cassete comprising the C-X-C motif chemokine receptor and one or more exogenous polynucleotides encoding a polypeptide of interest comprises a 2A sequence, such that the C-X-C motif chemokine receptor and the additional polynucleotide(s) are in a single open reading frame (ORF). The bi-cistronic design allows coordinated expression of multiple polynucleotides both in timing and quantity, and under the same control mechanism that may be chosen to incorporate, for example, an inducible promoter for the expression of the single ORF. Self-cleaving peptides are found in members of the Picornaviridae virus family, including aphthoviruses such as foot-and-mouth disease virus (FMDV), equine rhinitis A virus (ERAV), Thosea asigna virus (TaV) and porcine tescho virus- 1 (PTV-I) (Donnelly, ML, et al, J. Gen. Virol, 82, 1027-101 (2001); Ryan, MD, et al., J. Gen. Virol., 72, 2727-2732 (2001)), and cardioviruses such as Theilovirus (e.g., Theiler's murine encephalomyelitis) and encephalomyocarditis viruses. The 2A peptides derived from FMDV, ERAV, PTV-I, and TaV areAttorney Docket No.: FATE-173 / 01WO sometimes also referred to as “F2A”, “E2A”, “P2A”, and “T2A”, respectively. In some embodiments, the exogenous polynucleotides that could be co-expressed with the C-X-C motif chemokine receptor encode one or more polypeptides comprising a CAR, a CD16 or a variant thereof, a cytokine, a cytokine receptor, a cytokine signaling complex, a chimeric fusion receptor, a chimeric Fc receptor, an engager, a checkpoint inhibitor, an Fc receptor, or an antibody or functional variant or fragment thereof. In one embodiment, the exogenous polynucleotides that are co-expressed with the C-X-C motif chemokine receptor in a bi-cistronic cassette do not encode a CAR. In one embodiment, at least one exogenous polynucleotide that is co-expressed in a bi-cistronic cassette with the C-X-C motif chemokine receptor encodes an exogenous CD16.

Exogenously introduced TGFβ Redirector Receptor [000144] Transforming growth factor beta (TGFβ) is a multipotent immunosuppressive cytokine with complex roles in tumorigenesis including epithelial to mesenchymal transition, angiogenesis, tumor cell motility and metastasis, cancer associated fibroblast (CAF) proliferation, and immunosuppression. TGFβ exists in its latent form in the tumor microenvironment, and is known to suppress T cell effector function, in part, through Smad- mediated downregulation of the target genes granzyme, perforin, and interferon. Furthermore, the detection of a TGFβ gene expression signature correlates with T cell exclusion from tumors and resistance to immunotherapy. One aspect of the present application provides a multi-element solid tumor targeting backbone design that incorporates a synthetic transforming growth factor beta receptor (TGFβR) signaling redirector receptor, among other editing as contemplated and described herein, to equip allogeneic effector cells, including those derived from genetically engineered iPSCs for better efficacy in tumors in general, and in solid tumors in particular. In general, a “signaling (or signal) redirector receptor” or “SRR” redirects the signaling of anAttorney Docket No.: FATE-173 / 01WO extracellular domain from a first receptor (e.g., a TGFβ receptor) through an intracellular domain from a different receptor (e.g., a cytokine receptor) by joining the extracellular domain of the first receptor and intracellular domains of the different receptor.

CD16 knock-in [000153] CD16 has been identified as two isoforms, Fc receptors FcγRIIIa (CD16a; NM_000569.6) and FcγRIIIb (CD16b; NM_000570.4). CD16a is a transmembrane protein expressed by NK cells, which binds monomeric IgG attached to target cells to activate NK cells and facilitate antibody-dependent cell-mediated cytotoxicity (ADCC). CD16b is exclusively expressed by human neutrophils. “High affinity CD16,” “non-cleavable CD16,” or “high affinity non-cleavable CD16” (abbreviated as hnCD16), as used herein, refers to various CD16 variants. The wildtype CD16 has low affinity and is subject to ectodomain shedding, a proteolytic cleavage process that regulates cell surface density of various cell surface molecules onAttorney Docket No.: FATE-173 / 01WO leukocytes upon NK cell activation. F176V (also called F158V in some publications) is an exemplary CD16 polymorphic variant having high affinity; whereas S197P variant is an example of genetically engineered non-cleavable version of CD16. An engineered CD16 variant comprising both F176V and S197P has high affinity and is non-cleavable, which was described in greater detail in WO2015 / 148926, the complete disclosure of which is incorporated herein by reference. In addition, a chimeric CD16 receptor with the ectodomain of CD16 essentially replaced with at least a portion of CD64 ectodomain can also achieve the desired high affinity and non-cleavable features of a CD16 receptor capable of carrying out ADCC. In some embodiments, the replacement ectodomain of a chimeric CD16 comprises one or more of EC1, EC2, and EC3 exons of CD64 (UniPRotKB_P12314 or its isoform or polymorphic variant).

In some embodiments, the exogenous CD16 is a high-affinity non-cleavable CD16 receptor (hnCD16). In some embodiments, the exogenous CD16 comprises at least a portion of the CD64 ectodomain. In some embodiments, the exogenous CD16 is in a form of a CD16-based chimeric Fc receptor (CFcR) that comprises a transmembrane domain, a stimulatory domain and / or a signaling domain that is not derived from CD16. [000156] In some embodiments, the primary-sourced or derived effector cells comprising the exogenous CD16 or variant thereof are NK lineage cells. In some embodiments, the primary- sourced or derived effector cells comprising the exogenous CD16 or variant thereof are T lineage cells. In some embodiments, the exogenous CD16 or functional variants thereof comprised in iPSC or effector cells has high affinity in binding to a ligand that triggers downstream signaling upon such binding. Non-limiting examples of ligands binding to the exogenous CD16 or functional variants thereof include not only ADCC antibodies or fragments thereof, but also to bi-, tri-, or multi- specific engagers or binders that recognize the CD16 or CD64 extracellular binding domains of the exognous CD16. Examples of bi-, tri-, or multi- specific engagers or binders are further described below in this application. As such, at least one of the aspects of the present application provides a derivative effector cell comprising a solid tumor targetingAttorney Docket No.: FATE-173 / 01WO backbone, or a cell population thereof, preloaded with one or more pre-selected ADCC antibodies through an exogenous CD16 expressed on the derivative effector cell, in an amount sufficient for therapeutic use in a treatment of a condition, a disease, or an infection as further detailed in this application, wherein the exogenous CD16 comprises an extracellular binding domain of CD64, or of a CD16 having F176V and S197P. [000157] In some other embodiments, an exogenous CD16 comprises a CD16-, or variants thereof, based CFcR. A chimeric Fc receptor (CFcR) is produced to comprise a non-native transmembrane domain, a non-native stimulatory domain and / or a non-native signaling domain by modifying or replacing the native CD16 transmembrane- and / or the intracellular-domain. The term “non-native” used herein means that the transmembrane, stimulatory or signaling domain are derived from a different receptor other than the receptor which provides the extracellular domain. [000158] The various embodiments of the CD16-based chimeric Fc receptor as described above are capable of binding, with high affinity, to the Fc region of an antibody or fragment thereof; or to a bi-, tri-, or multi- specific engager or binder. Upon binding, the stimulatory and / or signaling domains of the chimeric receptor enable the activation and cytokine secretion of the effector cells, and the killing of the tumor cells targeted by the antibody, or the bi-, tri-, or multi- specific engager or binder having a tumor antigen binding component as well as the Fc region. Without being limited by theory, through the non-native transmembrane, stimulatory and / or signaling domains, or through an engager binding to the ectodomain, of the CD16-based chimeric Fc receptor, the CFcR could contribute to effector cells’ killing ability while increasing the effector cells’ proliferation and / or expansion potential. The antibody and the engager can bring tumor cells expressing the antigen and the effector cells expressing the CFcR into close proximity, which also contributes to the enhanced killing of the tumor cells. . [000159] In some embodiments, the present disclosure also provides a derivative NK or T cell comprising a solid tumor targeting backbone, or a cell population thereof, preloaded with one or more pre-selected ADCC antibodies in an amount sufficient for therapeutic use in a treatment of a condition, a disease, or an infection as further detailed in this application.

[000160] As provided further, the cell or population thereof , comprising the solid tumor targeting backbone, and optionally a CAR, and an exogenous CD16 or a variant thereof (“CD16exo” in Table 4), may further comprise one or more additional engineered modalities described herein, and / or as shown in Table 4. Additionally provided in this application is a master cell bank comprising single cell sorted and expanded clonal engineered iPSCs having at least one phenotype as provided herein, including but not limited to, a solid tumor targeting backbone comprising, among other genetic modalities, an exogenous CD16 or a variant thereof, wherein the cell bank provides a platform for additional iPSC engineering and a renewable source for manufacturing off-the-shelf, engineered, homogeneous cell therapy products, including but not limited to derivative NK and T cells, which are well-defined and uniform in composition, and can be mass produced at significant scale in a cost-effective manner. 4. Allo-Immune Defense Receptor (ADR) expression [000161] Unwanted activation of T- and NK- cells often promotes allo-immune reactions leading to development of graft-versus-host disease (GvHD). Although some steps may be taken to reduce the reactivity of allogeneic cells in the recipient individual, such cells would still be targeted by the immune system of the recipient (primarily T- and NK-cells), which would recognize them as foreign leading to rejection and limiting therapeutic benefit. On the other hand, modulating a host immune system to reduce allo-immune reactions, for example, by lympho-conditioning using chemotherapy such as Cy / Flu (cyclophosphamide / fludarabine) often leads to associated hematologic toxicities, including increased susceptibility to severe infections, due to indiscrimitive lymphodepletion and a severely compromised immune system as a result. To control pathogenic conditions due to unwanted activation of the immune system, in various embodiments, the present application provides a solid tumor targeting backbone comprising an allo-immune defense receptor (ADR), among other components. Another aspect of the application provides immune cells, iPSCs, and iPSC-derived effector cells that are genetically engineered to comprise, among other editing as contemplated and described herein, a 4-1BB or CD38 specific allo-immune defense receptor (ADR) for effector cell potentiation as well as selective depletion of alloreactive host NK cells and T cells with upregulated 4-1BB and / or CD38 expression, the latter of which include pathogenic T cells, and regulatory T cells, while sparing resting cells in the recipient.

In some embodiments, the 41BB-ADR extracellular domain comprises 4-1BBL, or a fragment thereof effective to bind 4-1BB. In some embodiments, the 41BB-ADR extracellular domain comprises an amino acid sequence with at least about 85%, about 90%, about 95%, about 96%, about 97%, about 98%, or about 99% sequence identity to SEQ ID NO: 14.

CD38 knockout [000252] The cell surface molecule CD38 is highly upregulated in multiple hematologic malignancies derived from both lymphoid and myeloid lineages, including multiple myeloma and a CD20 negative B-cell malignancy, which makes it an attractive target for antibodyAttorney Docket No.: FATE-173 / 01WO therapeutics to deplete cancer cells. Antibody mediated cancer cell depletion is usually attributable to a combination of direct cell apoptosis induction and activation of immune effector mechanisms such as ADCC (antibody-dependent cell-mediated cytotoxicity). In addition to ADCC, the immune effector mechanisms in concert with the therapeutic antibody may also include antibody-dependent cell-mediated phagocytosis (ADCP) and / or complement-dependent cytotoxicity (CDC). [000253] Other than being highly expressed on malignant cells, CD38 is also expressed on plasma cells, as well as on NK cells and activated T and B cells. During hematopoiesis, CD38 is expressed on CD34+stem cells and lineage-committed progenitors of lymphoid, erythroid, and myeloid, and during the final stages of maturation which continues through the plasma cell stage. As a type II transmembrane glycoprotein, CD38 carries out cell functions as both a receptor and a multifunctional enzyme involved in the production of nucleotide-metabolites. As an enzyme, CD38 catalyzes the synthesis and hydrolysis of the reaction from NAD+to ADP-ribose, thereby producing secondary messengers CADPR and NAADP which stimulate release of calcium from the endoplasmic reticulum and lysosomes, critical for the calcium dependent process of cell adhesion. As a receptor, CD38 recognizes CD31 and regulates cytokine release and cytotoxicity in activated NK cells. CD38 is also reported to associate with cell surface proteins in lipid rafts, to regulate cytoplasmic Ca2+flux, and to mediate signal transduction in lymphoid and myeloid cells. [000254] In malignancy treatment, systemic use of CD38 antigen binding receptor transduced T cells has been shown to lyse the CD38+fractions of CD34+hematopoietic progenitor cells, monocytes, NK cells, T cells and B cells, leading to incomplete treatment responses and reduced or eliminated efficacy because of the impaired recipient immune effector cell function. In addition, in multiple myeloma patients treated with daratumumab, a CD38- specific antibody, NK cell reduction in both bone marrow and peripheral blood was observed, although other immune cell types, such as T cells and B cells, were unaffected despite their CD38 expression (Casneuf et al., Blood Advances.2017; 1(23):2105-2114). [000255] Without being limited by theories, the present application includes a strategy to leverage the full potential of CD38 targeted cancer treatment by knocking out CD38 in the effector cell, thereby overcoming CD38-specific antibody and / or CD38 antigen binding domain- induced effector cell depletion or reduction through fratricide. In addition, since CD38 is upregulated on activated lymphocytes such as T or B cells, by suppressing activation of these recipient lymphocytes using a CD38-specific antibody, such as daratumumab, in the recipient of allogeneic effector cells, host allorejection against these effector cells would be reduced and / or prevented, thereby increasing effector cell survival and persistency. As such, a CD38-specificAttorney Docket No.: FATE-173 / 01WO antibody, a secreted CD38-specific engager or a CD38-CAR (chimeric antigen receptor) against activation of recipient T, Treg, NK, and / or B cells can be used as a replacement for lymphodepletion using chemotherapy such as Cy / Flu (cyclophosphamide / fludarabine) prior to adoptive cell transferring. [000256] In addition, when targeting CD38+T and pbNK cells using CD38- effector cells in the presence of anti-CD38 antibodies or CD38 inhibitors, the depletion of CD38+alloreactive cells increases the NAD+(nicotinamide adenine dinucleotide, a substrate of CD38) availability and decreases NAD+consumption related cell death, which, among other advantages, boosts effector cell responses in an immunosuppressive tumor microenvironment and supports cell rejuvenation in aging, degenerative or inflammatory diseases. [000257] Moreover, the strategy as provided herein, i.e., CD38 knockout, is compatible with other components and processes contemplated for establishing a solid tumor targeting backbone as disclosed in this application, thereby providing an immune cell, an iPSC and differentiated effector cell therefrom comprising a CD38 knockout with additional backbone edits. As disclosed herein, in various embodiments, the solid tumor targeting backbone comprised in the iPSC line or a derivative thereof, comprises an TCR promoter-driven ADR and / or a cytokine, and a constitutively expressed TCE, in addition to edits comprising a CAR, a TGFβ-SRR, a C-X- C-motif chemokine receptor or a variant thereof, a CD16 variant, and a CD38 knockout, among other edits as provided herein. In some embodiments, the provided CD38negiPSC line optionally comprises one or more additional engineered modalities described herein, and as shown in Table 4. As such, these CD38negderivative effector cells comprising a solid tumor targeting backbone are protected against fratricide and allorejection when CD38 targeted therapeutic moieties are employed with the effector cells, among other advantages including improved metabolic fitness, increased resistance to oxidative stress and inducing a protein expression program in the effector cell that enhances cell activation and effector function. In addition, anti-CD38 monoclonal antibody therapy significantly depletes a patient’s activated immune system without adversely affecting the patient’s hematopoietic stem cell compartment. A CD38negderivative cell has the ability to resist CD38 antibody mediated depletion, and may be effectively administered in combination with an anti-CD38 antibody or CD38-CAR without the use of toxic conditioning agents, thereby reducing and / or replacing chemotherapy-based lymphodepletion. [000258] In one embodiment as provided herein, the CD38 knockout in an iPSC line is a bi- allelic knockout. In another embodiment, knocking out CD38 at the same time as inserting one or more transgenes, including a C-X-C-motif chemokine receptor or a variant thereof, a TGFβ- SRR, and / or a CD16 variant as provided herein, at a selected position in CD38 can be achieved, for example, by a CD38-targeted knock-in / knockout (CD38-KI / KO) construct. In someAttorney Docket No.: FATE-173 / 01WO embodiments of the construct, the construct comprises a pair of CD38 targeting homology arms for position-selective insertion within the CD38 locus. In some embodiments, the preselected targeting site is within an exon of CD38. The CD38-KI / KO constructs provided herein allow the transgene(s) to express either under the CD38 endogenous promoter or under an exogenous promoter comprised in the construct. When two or more transgenes are to be inserted at a selected location in the CD38 locus, a linker sequence, for example, a 2A linker or IRES, is placed between any two transgenes. The 2A linker encodes a self-cleaving peptide derived from FMDV, ERAV, PTV-I, and TaV (referred to as “F2A”, “E2A”, “P2A”, and “T2A”, respectively), allowing for separate proteins to be produced from a single translation. In some embodiments, insulators are included in the construct to reduce the risk of transgene and / or exogenous promoter silencing. The exogenous promoter comprised in a CD38-KI / KO construct may be CAG, or other constitutive, inducible, temporal-, tissue-, or cell type- specific promoters including, but not limited to CMV, EF1α, PGK, and UBC. [000259] In various embodiments, said iPSC is capable of directed differentiation to produce functional derivative hematopoietic cells including, but not limited to, mesodermal cells with definitive hemogenic endothelium (HE) potential, definitive HE, CD34+hematopoietic cells, hematopoietic stem and progenitor cells, hematopoietic multipotent progenitors (MPP), T cell progenitors, NK cell progenitors, myeloid cells, neutrophil progenitors, T cells, NKT cells, NK cells, B cells, neutrophils, dendritic cells, and macrophages. In some embodiments, the CD38 negative effector cells are NK lineage cells derived from iPSCs. In some embodiments, the CD38 negative effector cells are T lineage cells derived from iPSCs. In some embodiments, the iPSC and derivative cells thereof comprise a solid tumor targeting backbone comprising CD38negand at least two of: a polynucleotide encoding a C-X-C motif chemokine receptor or a variant thereof, a polynucleotide encoding a TGFβ-SRR, and a polynucleotide encoding a CD16 variant, and optionally include one or more additional genomic edits as described herein. 9. Stealth related edits [000260] Multiple HLA class I and class II proteins must be matched for histocompatibility in allogeneic recipients to avoid allogeneic rejection problems. Provided herein is an iPSC cell line and its derivative cells differentiated therefrom with eliminated or substantially reduced expression of HLA class I and / or HLA class II proteins. HLA class I deficiency can be achieved by functional deletion of any region of the HLA class I locus (chromosome 6p21), or deletion or disruption of HLA class-I associated genes including, but not limited to, beta-2 microglobulin (B2M) gene, TAP1 gene, TAP2 gene and Tapasin. For example, the B2M gene encodes a common subunit essential for cell surface expression of all HLA class I heterodimers. B2MAttorney Docket No.: FATE-173 / 01WO negative cells are HLA-I deficient. HLA class II deficiency can be achieved by functional deletion or disruption of HLA class II associated genes including, but not limited to, RFXANK, CIITA, RFX5 and RFXAP. CIITA is a transcriptional coactivator, functioning through activation of the transcription factor RFX5 required for class II protein expression. CIITA negative cells are HLA-II deficient. As such, this application provides an iPSC and derivative cells therefrom comprising HLA-I and / or HLA-II deficiency, for example by lacking B2M and / or CIITA expression, wherein the obtained derivative effector cells enable allogeneic cell therapies by eliminating the need for MHC (major histocompatibility complex) matching, and avoiding recognition and killing by host (allogeneic) T cells. [000261] Furthermore, a lack of HLA class I expression leads to lysis by host NK cells. Therefore, in addition to the above-discussed approach of CD38 conditioning to remove activated CD38-expressing host NK cells, to overcome this “missing self” response, HLA-E, HLA-G or other non-classical HLA-I proteins may be optionally knocked in to avoid NK cell recognition and killing of the HLA-I deficient effector cells derived from an engineered iPSC. In one embodiment, the provided HLA-I deficient iPSC and its derivative cells further comprise HLA-G knock-in. [000262] Alternatively, in one embodiment, the provided HLA-I deficient iPSC and its derivative cells further comprise one or both of CD58 knockout and CD54 knockout. CD58 (or LFA-3) and CD54 (or ICAM-1) are adhesion proteins initiating signal-dependent cell interactions, and facilitating cell, including immune cell, migration. It was previously shown that CD58 and / or CD54 disruption effectively reduces the susceptibility of HLA-I deficient iPSC-derived effector cells to allogeneic NK cell killing. While it was shown that CD58 knockout has a higher efficiency in reducing allogeneic NK cell activation than CD54 knockout, double knockout of both CD58 and CD54 was shown to provide the most enhanced reduction of NK cell activation. In some observations, the CD58 and CD54 double knockout is even more effective than HLA-G overexpression for HLA-I deficient cells in overcoming “missing-self” effect. [000263] As provided herein, in some embodiments, the iPSC and its derivative cells comprising a solid tumor targeting backbone comprising two or more of: a C-X-C-motif chemokine receptor or a variant thereof, a TGFβ-SRR, and a CD16 variant. In some embodiments, said iPSC and its derivative cells are CD58 negative. In some embodiments, said iPSC and its derivative cells are CD54 negative. In yet some other embodiments, said iPSC and its derivative cells are CD54 negative and CD58 negative. [000264] In some embodiments, the engineering for HLA-I and / or HLA-II deficiency may be bypassed, or kept intact, by expressing an inactivation CAR targeting an upregulated surfaceAttorney Docket No.: FATE-173 / 01WO protein in activated recipient immune cells to avoid allorejection. In some embodiments, the upregulated surface protein in the activated recipient immune cells includes, but is not limited to, CD38, CD25, CD69, CD44, 4-1BB, OX40, or CD40L. When the cell expresses such an inactivation CAR, it is preferable that the cell does not express, or has knockout of, the same surface protein targeted by CAR. In some embodiments, the inactivation CAR comprises at least one of a CD38-CAR, a CD25-CAR, a CD69-CAR, a CD44-CAR, a 4-1BB-CAR, an OX40- CAR, and a CD40L-CAR. [000265] Additionally provided in this application is a master cell bank comprising single cell sorted and expanded clonal engineered iPSCs having at least one phenotype as provided herein, including but not limited to, a solid tumor targeting backbone as described herein and HLA modification (“HLA” in Table 4: HLA-I and / or HLA-II deficiency with or without HLA-E or HLA-G knock in, or with knockout of one or both of CD58 and CD54), wherein the cell bank provides a platform for additional iPSC engineering and a renewable source for manufacturing off-the-shelf, engineered, homogeneous cell therapy products, including but not limited to derivative NK and T cells, which are well-defined and uniform in composition, and can be mass produced at significant scale in a cost-effective manner. 10. Genetically engineered iPSC line and derivative cells provided herein [000266] In light of the above, the present application provides an immune cell, an iPSC, an iPS cell line cell, or a population thereof, and a derivative functional cell obtained from differentiating the iPSC, wherein each cell comprises a solid tumor targeting backbone comprising an TCR promoter-driven ADR and / or a cytokine, and a constitutively expressed TCE, in addition to edits comprising a CAR, a TGFβ-SRR, a C-X-C-motif chemokine receptor or a variant thereof, a CD16 variant, and a CD38 knockout, among other modifications as described in the application, wherein the cell is an eukaryotic cell, an animal cell, a human cell, an induced pluripotent cell (iPSC), an iPSC-derived effector cell, an immune cell, or a feeder cell. In some embodiments, said cells are suitable for homing or migration of the effectors to tumor sites for CAR targeted tumor killing. In some embodiments, the tumor cells at the tumor sites secrete or overexpress a chemokine that binds to a C-X-C-motif chemokine receptor or a variant thereof. In some embodiments, the C-X-C motif chemokine receptor comprises CXCR2 or CXCR3. In some embodiments, the secreted or overexpressed chemokine by the tumor cells at the tumor sites comprises IL8 (CXCL8). In some embodiments, the functional derivative cells are hematopoietic cells including, but not limited to, mesodermal cells with definitive hemogenic endothelium (HE) potential, definitive HE, CD34+hematopoietic cells, hematopoietic stem and progenitor cells, hematopoietic multipotent progenitors (MPP), T cell progenitors, NK cellAttorney Docket No.: FATE-173 / 01WO progenitors, myeloid cells, neutrophil progenitors, T lineage cells, NKT lineage cells, NK lineage cells, B lineage cells, neutrophils, dendritic cells, and macrophages.

[000267] Said effector cells have improved ability to home or migrate to, and remain in, turmor sites which include solid tumors, and provide a tumor antigen dual targeting mechanism to tackle tumor antigen heterogeneity and tumor antigen escape. The dual targeting through CAR binding and CD16-mediated ADCC further increases tumor targeting precision, enhancing tumor killing and minimizing the impact of tumor antigen escape. [000268] In some further embodiments, the iPSC, iPS cell line cell, or clonal population thereof, and / or derivative effector cells therefrom comprising a solid tumor targeting backbone as described herein, wherein the solid tumor targeting backbone further comprises CD38 knockout, and said cells are suitable for a subject undergoing an adoptive cell therapy.

In some embodiments, said cells have the ADR and / or a cytokine inserted in a TCR constant region (TRAC or TRBC), leading to TCR knockout, and optionally placing ADR and / or cytokine expression under the control of the endogenous TCR promoter to promote T cell differentiation, T cell identity and lineage commitment, and to avoid T cell exhaustion. The disruption of the constant region of TCRα or TCRβ (TRAC or TRBC) produces a TCRnegcell. TCRnegcells do not require HLA matching, have reduced alloreactivity, and are able to prevent GvHD (Graft versus Host Disease) when used in allogeneic adoptive cell therapies.

[000281] In some embodiments, the therapeutic antibody is a monoclonal antibody. In some embodiments, the therapeutic antibody is a humanized antibody, a humanized monoclonal antibody, or a chimeric antibody. In some embodiments, the therapeutic antibody, or antibody fragment, specifically binds to a viral antigen. In other embodiments, the antibody, or antibody fragment, specifically binds to a tumor antigen. In some embodiments, the tumor- or viral- specific antigen activates the administered iPSC-derived effector cells to enhance their killing ability. In some embodiments, the therapeutic antibodies suitable for combinational treatment as an additional therapeutic agent to the administered iPSC-derived effector cells include, but are not limited to, anti-CD20 antibodies (rituximab, veltuzumab, ofatumumab, ublituximab, ocaratuzumab, obinutuzumab), anti-HER2 antibodies (trastuzumab, pertuzumab), anti-CD52 antibodies (alemtuzumab), anti-EGFR antibodies (cetuximab), anti-GD2 antibodies (dinutuximab), anti-PDL1 antibodies (avelumab), anti-CD38 antibodies (daratumumab, isatuximab, MOR202), anti-CD123 antibodies (7G3, CSL362), anti-SLAMF7 antibodies (elotuzumab), anti-MICA / B antibodies (7C6, 6F11, 1C2) and their humanized or Fc modified variants or fragments or their functional equivalents and biosimilars. In some embodiments, the antibodies suitable for combinational treatment as an additional therapeutic agent to the administered iPSC-derived effector cells further include bi-specific or multi-specific antibodies that target more than one antigen or epitope on a target cell or recruit effector cells (e.g., T cells, NK cells, or macrophage cells) toward target cells while targeting the target cells. Such bi- specific or multi-specific antibodies function as engagers capable of directing an effector cell (e.g., a T cell, a NK cell, an NKT cell, a B cell, a macrophage, and / or a neutrophil) to a tumorAttorney Docket No.: FATE-173 / 01WO cell and activating the immune effector cell, and have shown great potential to maximize the benefits of antibody therapy.

In various embodiments of said combination, the CAR targets a solid tumor antigen as set forth herein. In various embodiments of said combination, the exogenous CD16 is hnCD16. Without being limited by the theory, hnCD16 provides enhanced ADCC of the monoclonal antibody, whereas the CAR not only targets a specific tumor antigen but also prevents tumor antigen escape using a dual targeting strategy in combination with a monoclonal antibody targeting a different tumor antigen. 13. Checkpoint inhibitors [000284] Checkpoints are cell molecules, often cell surface molecules, capable of suppressing or downregulating immune responses when not inhibited. It is now clear that tumors co-opt certain immune-checkpoint pathways as a major mechanism of immune resistance, particularly against T cells that are specific for tumor antigens. Checkpoint inhibitors (CIs) are antagonists capable of reducing checkpoint gene expression or gene products, or deceasing activity of checkpoint molecules, thereby blocking inhibitory checkpoints, and restoring immune system function. The development of checkpoint inhibitors targeting PD1 / PDL1 or CTLA4 hasAttorney Docket No.: FATE-173 / 01WO transformed the oncology landscape, with these agents providing long term remissions in multiple indications. However, many tumor subtypes are resistant to checkpoint blockade therapy, and relapse remains a significant concern. Thus, one aspect of the present application provides a therapeutic approach to overcome CI resistance by including genomically-engineered functional iPSC-derived cells as provided herein in a combination therapy with CI. In one embodiment of the combination therapy described herein, the iPSC-derived cells are NK cells. In another embodiment of the combination therapy described herein, the iPSC-derived cells are T cells. In addition to exhibiting direct antitumor capacity, the derivative NK cells provided herein have been shown to resist PDL1-PD1 mediated inhibition, and to have the ability to enhance T cell migration, to recruit T cells to the tumor microenvironment, and to augment T cell activation at the tumor site. Therefore, the tumor infiltration of T cells facilitated by the functionally potent genomically engineered derivative NK cells indicate that said NK cells are capable of synergizing with T cell targeted immunotherapies, including the checkpoint inhibitors, to relieve local immunosuppression and to reduce tumor burden. [000285] In some embodiments of the combination therapy, the checkpoint inhibitor is used in combination with a population of the effector cells comprising a solid tumor targeting backbone as described herein by concurrent or consecutive administration thereof to a subject. In some other embodiments, the checkpoint inhibitor is expressed by the effector cells by genetically engineering an iPSC using an exogenous polynucleotide sequence encoding said checkpoint inhibitor, or a fragment or variant thereof, and directing differentiation of the engineered iPSC.

[000288] In some embodiments, the antagonist inhibiting any of the above checkpoint molecules is an antibody. In some embodiments, the checkpoint inhibitory antibodies may be murine antibodies, human antibodies, humanized antibodies, a camel Ig, a single variable new antigen receptor (VNAR), a shark heavy-chain-only antibody (Ig NAR), chimeric antibodies, recombinant antibodies, or antibody fragments thereof. Non-limiting examples of antibody fragments include Fab, Fab′, F(ab′)2, F(ab′)3, Fv, single chain antigen binding fragments (scFv), (scFv)2, disulfide stabilized Fv (dsFv), minibody, diabody, triabody, tetrabody, single-domain antigen binding fragments (sdAb, Nanobody), recombinant heavy-chain-only antibody (VHH), and other antibody fragments that maintain the binding specificity of the whole antibody, which may be more cost-effective to produce, more easily used, or more sensitive than the whole antibody.

As such, the coding sequences of the checkpoint inhibitor and the CAR may be in a single open reading frame (ORF). When the checkpoint inhibitor is delivered, expressed and secreted as a payload by the derivative effector cells capable of infiltrating the tumor microenvironment (TME), it counteracts the inhibitory checkpoint molecule upon engaging the TME, allowing activation of the effector cells by activating modalities such as CAR or activating receptors.

Chimeric Fusion Receptor (CFR) [000292] Also provided herein, according to some embodiments, are Chimeric Fusion Receptors (CFRs). In general, a CFR is a fusion protein with a receptor functionality. In some embodiments, a CFR enables an effector cell to initiate an appropriate signal transduction cascade through CFR binding with a selected agonist for enhanced therapeutic properties of the effector cell expressing the CFR. Such enhanced effector cell therapeutic properties may include, but are not limited to, increased activation and cytotoxicity, acquired dual targeting capability, prolonged persistency, improved trafficking and tumor penetration, enhanced ability in priming, activating or recruiting bystander immune cells to tumor sites, enhanced ability to resist immunosuppression, improved ability in rescuing tumor antigen escape, and / or controlled cell signaling feedback, metabolism and apoptosis.Attorney Docket No.: FATE-173 / 01WO [000293] In some embodiments, a CFR comprises an ectodomain, a transmembrane domain, and an endodomain, wherein the ectodomain, the transmembrane domain and the endodomain do not comprise any endoplasmic reticulum (ER) retention signals or endocytosis signals. The ectodomain of the CFR is for initiating signal transduction upon binding to an engager; the transmembrane domain is for membrane anchoring of the CFR; and the endodomain comprises at least one signaling domain that regulates (e.g., activates or deactivates) a signaling pathway of choice for enhancing cell therapeutic properties including, but not limited to, tumor killing, persistence, mobility, differentiation, TME counteracting, and / or controlled apoptosis. The elimination of ER retention signals from the CFR permits CFR cell surface presentation by itself when expressed, and the elimination of endocytosis signals from the CFR reduces CFR internalization and surface downregulation. In some embodiments, it is important to either select domain components that have neither ER retention nor endocytosis signals, or remove ER retention or endocytosis signals from selected components of the CFR using molecular engineering tools. In addition, the domains of the CFRs as provided by some embodiments herein are modular, meaning for a given endodomain of a CFR, the ectodomain of the CFR is switchable depending on the binding specificity of a selected agonist, such as an antibody, a BiTE, a TriKE, or any other type of engager, to be used with said CFR; and for a given ectodomain and a specificity matching agonist, the endodomain is switchable depending on the desired signaling pathway to be activated. Additionally, the transmembrane domain in accordance with some embodiments is switchable for a given ectodomain and / or a given endodomain, so long as the transmembrane domain does not comprise any endoplasmic reticulum (ER) retention signals or endocytosis signals. Non-limiting examples of CFRs are described in US20240033355A1, which are incorporated herein by reference. II. Methods for Targeted Genome Editing at Selected Locus in iPSCs [000294] Genome editing, or genomic editing, or genetic editing, as used interchangeably herein, is a type of genetic engineering in which DNA is inserted, deleted, and / or replaced in the genome of a targeted cell. Targeted genome editing (interchangeable with “targeted genomic editing” or “targeted genetic editing”) enables insertion, deletion, and / or substitution at pre- selected sites in the genome. When an endogenous sequence is deleted at the insertion site during targeted editing, an endogenous gene comprising the affected sequence may be knocked-out or knocked-down due to the sequence deletion. Therefore, targeted editing may also be used to disrupt endogenous gene expression with precision. Similarly used herein is the term “targeted integration,” referring to a process involving insertion of one or more exogenous sequences, with or without deletion of an endogenous sequence at the insertion site. In comparison, randomlyAttorney Docket No.: FATE-173 / 01WO integrated genes are subject to position effects and silencing, making their expression unreliable and unpredictable. For example, centromeres and sub-telomeric regions are particularly prone to transgene silencing. Reciprocally, newly integrated genes may affect the surrounding endogenous genes and chromatin, potentially altering cell behavior or favoring cellular transformation. Therefore, inserting exogenous DNA in a pre-selected locus such as a safe harbor locus, or genomic safe harbor (GSH) is important for safety, efficiency, copy number control, and for reliable gene response control. [000295] Targeted editing can be achieved either through a nuclease-independent approach, or through a nuclease-dependent approach. In the nuclease-independent targeted editing approach, homologous recombination is guided by homologous sequences flanking an exogenous polynucleotide to be inserted, through the enzymatic machinery of the host cell. [000296] Alternatively, targeted editing could be achieved with higher frequency through specific introduction of double strand breaks (DSBs) by specific rare-cutting endonucleases. Such nuclease-dependent targeted editing utilizes DNA repair mechanisms including non-homologous end joining (NHEJ), which occurs in response to DSBs. Without a donor vector containing exogenous genetic material, the NHEJ often leads to random insertions or deletions (in / dels) of a small number of endogenous nucleotides. In comparison, when a donor vector containing exogenous genetic material flanked by a pair of homology arms is present, the exogenous genetic material can be introduced into the genome during homology directed repair (HDR) by homologous recombination, resulting in a “targeted integration.” In some situations, the targeted integration site is intended to be within a coding region of a selected gene, and thus the targeted integration could disrupt the gene expression, resulting in simultaneous knock-in and knock-out (KI / KO) in one single editing step. [000297] Inserting one or more transgenes can be achieved at a selected position such as a genomic safe harbor (GSH) locus or at a gene locus of interest (GOI), and may also thereby knock out the gene at the locus of insertion.
