[0002] Incorporated by reference in its entirety herein is a computer-readable nucleotide / amino acid sequence listing submitted concurrently herewith and identified as follows: 372,626 One Byte XML (Extensible Markup Language) file named "775202_SequenceListing.xml," created on March 27, 2026.BACKGROUND
[0003] Adoptive immunotherapy using genetically modified immune effector cells has demonstrated clinical activity in oncology. Immune effector cells, including T lymphocytes, natural killer (NK) cells, NKT cells, y5 T cells, and other immune cell populations such as macrophages, may be engineered to express recombinant antigen-recognition receptors, including chimeric antigen receptors (CARs). Such constructs enable immune effector cells to recognize tumor-associated antigens in a manner that is independent of human leucocyte antigen (HLA) / major histocompatibility complex (MHC) presentation.Leydig 775202
[0004] Clinical successes in hematologic malignancies have validated the therapeutic potential of CAR-expressing immune effector cells. However, the extension of these approaches to solid tumors remains an area of ongoing development. In contrast to hematologic malignancies, solid tumors present both structural and immunologic barriers that can limit the activity of adoptively transferred immune cells. These barriers include, for example, dense stromal architecture and extracellular matrix deposition, heterogeneous antigen expression across tumor cell populations, immunosuppressive tumor microenvironments, physical compartmentalization of tumor tissue, and restricted immune cell trafficking and retention. In addition, tumor-associated antigens in solid tumors may exhibit spatial heterogeneity within primary and metastatic lesions, further complicating effective targeting. As a result, therapeutic strategies that rely solely on the infusion of premanufactured immune effector cells may not fully address the dynamic and localized immune context of solid tumors.
[0005] Despite advances in immune checkpoint inhibition and cellular immunotherapy, many solid tumors remain refractory to durable immune-mediated clearance. Accordingly, there remains an ongoing need in the art for systems capable of generating engineered immune effector cells in vivo, targeting diverse solid tumor antigens, functioning within the structural and immunologic constraints of solid tumors, and providing sustained effector activity over time.BRIEF DESCRIPTION OF THE DRAWINGS

[0064] In aspects, the present disclosure provides a vector production system comprising one or more nucleotide sequences encoding: (a) a fusogenic membrane glycoprotein (FMG) or functional fragment or derivative thereof, (b) a chimeric antigen receptor (CAR) comprising a first antigen binding domain, a transmembrane domain, an intracellular cell signaling domain, and optionally a second antigen binding domain and a third antigen binding domain; wherein the first antigen binding domain has antigenic specificity for an antigen expressed on a solid tumor. In aspects, the vector production system disclosed herein comprises one or more nucleotide sequences encoding: (c) a second CAR comprising a first antigen binding domain, a transmembrane domain, an intracellular cell signaling domain, and optionally a second antigen binding domain and a third antigen binding domain; wherein the first antigen binding domain of the second CAR has antigenic specificity for an antigen expressed on a solid tumor, B cell, or a macrophage.
[0065] As used herein, “antigen binding domain” refers to a region of a protein that specifically recognizes and / or binds to a particular antigen. In aspects, the antigen binding domain is an extracellular antigen-binding domain. In aspects, the antigen binding domain is configured to recognize a target antigen present on the surface of a cancer cell, an infected cell, or other pathological cell. In aspects, the antigen binding domain is derived from an antibody or antibody fragment. In aspects, the antigen-binding domain comprises a singlechain variable fragment (scFv).
[0066] As used herein, “single-chain variable fragment” or “scFv” refers to a protein fragment derived from an antibody’s variable regions, such as an antigen-binding site. In aspects, the scFv retains the antigen-binding specificity and affinity of the antibody from which it is derived.
[0067] As used herein, “antigenic specificity” refers to the ability of an immune system component, such as an antibody, CAR, or TCR, to recognize and bind to a specific antigen with high selectivity and affinity.Leydig 775202
[0068] As used herein, “chimeric antigen receptor” or “CAR” refers to a protein engineered to equip immune cells, such as T cells, with the ability to recognize and / or bind specific antigens. In aspects, the CAR comprises an antigen-binding domain, such as an extracellular antigen-binding domain, a transmembrane domain, and a signaling domain, such as a T cell signaling domain. In aspects, the CAR comprises a spacer or hinge region between the antigen-binding domain and the transmembrane domain. In certain aspects, the CAR further comprises a selection marker, such as an antibiotic resistance gene or fluorescent protein.
[0069] As used herein, “T cell signaling domain” refers to a component of a CAR or a T cell receptor (TCR) construct that transmits intracellular signals upon antigen recognition by a T cell. In aspects, the T cell signaling domain comprises signaling motifs derived from proteins involved in T cell activation and proliferation, such as CD28. In aspects, the T cell signaling domain facilitates downstream cellular responses such as cytokine release, cytotoxicity, and proliferation.
[0070] As used herein, “transmembrane domain” refers to a structural motif of a protein that spans the lipid bilayer of a cell membrane.
[0071] As used herein, “for example,” “for instance,” “such as,” or “including” are meant to introduce examples that further clarify more general subject matter. Unless otherwise expressly indicated, such examples are provided only as an aid for understanding aspects illustrated in the present disclosure, and are not meant to be limiting in any fashion. Nor do these phrases indicate any kind of preference for the disclosed aspect.
[0072] As used herein, “retroviral vector” refers to a viral vector derived from retroviruses (i.e., RNA viruses capable of reverse transcription and integration of their genetic material into a host cell genome).
[0073] As used herein, “solid tumor” refers to a mass of abnormal cells within a tissue or an organ. In aspects, the solid tumor is benign. In aspects, the solid tumor is malignant (i.e., cancerous).
[0074] One possible explanation for the remarkable efficacy of CAR-T cell therapies directed against B-cell lineage targets is that they are continuously restimulated and amplified in normal lymphoid tissues via their interactions with normal antigen-positive target cells in close proximity to macrophages, dendritic cells and other types that together provide an optimal mix of appropriate costimulatory signals. Continuous re-exposure of CAR-T cells to target antigen may be a driver to sustain the supply of functional CAR-T cells in theLeydig 775202circulation over a long period of time, thereby increasing the probability that the T cells will ultimately penetrate the tumor and mediate their antitumor activity.
[0075] In aspects, the present disclosure provides materials and methods that drive the restimulation, amplification and / or maturation of solid tumor-targeted CAR-T cells in normal lymphoid tissues. In aspects, the present disclosure supports continued in vivo survival, restimulation and / or amplification of circulating CAR-T cells in mammals with solid tumors, such that they are capable of mounting a sustained attack on accessible parts of the tumor into which the T cells are able to extravasate (most notably the invasive edge). Without subscribing to any particular theory, it is believed that by sustaining their attack at the receding periphery of the solid tumor, the CAR-T cells should ultimately be able to eliminate the tumor.
[0076] As used herein, “normal cell” or “healthy cell” refers to a non-cancerous cell that exhibits regulated growth, differentiation, and function within the confines of physiological control mechanisms. Unlike cancer cells / tumor cells, which exhibit uncontrolled proliferation, abnormal morphology, and dysfunctional behavior, normal cells maintain homeostasis, respond appropriately to signals from their environment, and / or contribute to the proper functioning of an organism. In aspects, a normal cell or healthy cell refers to a cell comprising one or more genetic mutations or abnormalities which do not interfere with the cell’s growth cycle, morphology, or function. In aspects, a normal cell or healthy cell refers to a precancerous cell or a dysplastic cell.
[0077] In aspects, the CARs disclosed herein have antigenic specificity for one or more antigens selected from tumor cell-associated antigens and tumor microenvironment-associated antigens. In aspects, the CARs disclosed herein comprises one or more antigen binding domains capable of binding to two or more distinct tumor-associated antigens. Such domains may be configured as dual CARs, tandem CARs or multi-specific CARs (FIG. 1). In aspects, the CARs disclosed herein comprising one or more antigen binding domains described herein address tumor antigen heterogeneity by enabling targeting of multiple antigens, modulation of antigen expression, or engagement of tumor cells and / or tumor-associated cells. In aspects, engineered immune effector cells may enhance the breadth, durability, and efficacy of the antitumor response. In aspects, the CARs disclosed herein comprising multiple antigen binding domains bind different epitopes of the same antigen, thereby reducing the likelihood of antigen escape due to epitope loss or modification.
[0078] In aspects, the present disclosure provides a vector production system wherein the second CAR comprises a second antigen binding domain, wherein the second antigen bindingLeydig 775202domain has antigenic specificity for an antigen expressed on a solid tumor, B cell, or a macrophage. In aspects, the present disclosure provides a vector production system wherein the second CAR comprises a third antigen binding domain, wherein the third antigen binding domain has antigenic specificity for an antigen expressed on a solid tumor, B cell, or a macrophage. In aspects, the present disclosure provides a vector production system wherein the first CAR comprises a second antigen binding domain, wherein the second antigen binding domain has antigenic specificity for an antigen expressed on a solid tumor, B cell, or a macrophage. In aspects, the present disclosure provides a vector production system wherein the first CAR comprises a third antigen binding domain, wherein the third antigen binding domain has antigenic specificity for an antigen expressed on a solid tumor, B cell, or a macrophage.

[0082] Solid tumor antigens are a diverse array of antigens expressed on the surface of tumor cells and on cells within the tumor microenvironment, including stromal cells, vascular endothelial cells, and infiltrating immune cells. In addition, tumor-associated molecules may be derived from intracellular proteins that are processed and presented or otherwise made accessible for immune recognition. Solid tumor antigens are typically, but not exclusively, membrane-associated molecules, including cell surface proteins, glycoproteins, glycolipids, receptors, adhesion molecules, and transporters. In some contexts, intracellular proteins or peptides may also contribute to the antigenic landscape of solid tumors through presentation or indirect targeting mechanisms. The expression of these molecules may occur on malignant cells as well as on non-malignant cells within the tumor microenvironment, which can contribute to tumor growth, maintenance, and immune evasion.
[0083] In aspects, the antigen expressed on the solid tumor is presented on an antigen presenting cell (APC). In aspects, the antigen expressed on the lymphoid cell is presented on an APC.
[0084] Solid tumor antigens can be broadly categorized based on their biological characteristics. These include differentiation antigens associated with specific tissue lineages; self-antigens that are overexpressed in tumor cells relative to normal tissues; oncofetal antigens that are expressed during development and re-expressed in malignancy; tumor-associated glycoproteins and mucins; and cell surface receptors, including growth factor receptors and immune regulatory molecules. In addition, tumor-specific antigens may arise from somatic mutations, including neoantigens unique to tumor cells. Antigens expressed onLeydig 775202non-malignant components of the tumor microenvironment, such as fibroblasts and endothelial cells, may also serve as potential targets.

[0085] In many cases, tumor-associated antigens are not exclusively expressed by tumor cells but may also be present at low or basal levels in normal tissues. However, these antigens are often expressed at higher levels, at greater density, or in altered spatial or temporal patterns in tumor tissue compared to normal tissue. These differences in expression can be utilized to enable selective targeting of tumor cells while minimizing effects on normal tissues.
[0086] Solid tumors are frequently characterized by heterogeneous expression of tumor-associated antigens, wherein distinct tumor cell populations within a single tumor or acrossLeydig 775202metastatic lesions may express different antigens or express the same antigen at varying levels.

[0098] Armoring strategies for engineered immune effector cells have been explored as an approach to enhance therapeutic activity in solid tumors, where the tumor microenvironment (TME) can limit immune cell function. Armoring strategies may involve the expression of additional functional molecules that support immunological cell activation, persistence, and interaction with the surrounding environment. For example, cytokines can play a role in coordinating both adaptive and innate immune responses. Certain cytokines may promote proliferation, survival, and sustained activity of engineered T cells, thereby enhancing persistence within the TME. In parallel, other cytokines can modulate components of the innate immune system, including macrophages and dendritic cells, promoting their activation and differentiation into professional antigen-presenting cells capable of supporting endogenous immune responses. In this manner, cytokine-mediated signaling may contribute to bridging innate and adaptive immunity, thereby amplifying antitumor activity beyond direct cytotoxic effects. In addition, expression of enzymes capable of modifying the extracellular matrix has been investigated as a means to improve immune cell infdtration into solid tumors, where dense stromal architecture can otherwise impede access to tumor cells.

[0105] As used herein, “fusogenic membrane glycoprotein” or “FMG” comprises a viral envelope glycoprotein capable of fusing lipid bilayers. A FMG mediates binding of a virus to a receptor on a cell, which binding then mediates entry of the virus into the cell and infection of the cell. A FMG or functional fragment or derivative thereof as described herein can be used to pseudotype a type of virus or virus-like particle that is not the native / natural virus of the FMG.
[0106] As used herein, “functional fragment” of a FMG means a FMG that is not a full length FMG but is a portion of a parent FMG (e.g., a truncated form of a full length FMG), where the portion retains the fusion function of the parent full length FMG. As used herein, “functional derivative” or “functional variant” of a FMG means a FMG that has been modified, e.g., by conservative amino acid substitution, where the FMG retains the fusion function of the parent full length FMG. As used herein, “functional fragment or derivative” and “functional fragment or variant” encompass the meanings of both “functional fragment” and “functional derivative” / “functional variant.”Leydig 775202
[0107] The “fusion function” of a FMG means that a FMG, when part of a virus, can initiate fusion of the virus with a target cell, e.g., such that the virus can infect the target cell. Such fusion can be due to the interaction of the FMG with its natural receptor or the interaction of the FMG with a different receptor (e.g., the FMG is blinded to its natural receptor, such that the FMG is engineered to reduce or abolish its natural receptor binding specificity, and the FMG is re-targeted to a new receptor). A functional fragment and / or functional derivative / functional variant of a FMG can be within a recombinant fusion protein. As used herein, the term “natural receptor” refers to an endogenously expressed receptor in an organism that a FMG is capable of binding. Any FMG may have more than one natural receptor. The binding domain of a receptor protein of the recombinant protein can be any binding domain of a receptor protein that is capable of binding to or interacting with a FMG or a functional fragment or derivative thereof of the vector production system, and wherein the FMG or functional fragment or derivative thereof is capable of binding to or interacting with the binding domain of the receptor protein of the recombinant protein, including but not limited to any natural receptor of the viral FMG.

[0109] In aspects, each FMG is optionally chimeric. Whether one FMG is chimeric is independent of whether another FMG is chimeric. For example, in aspects where the vector production system comprises at least two FMGs, at least one FMG is chimeric and at least one FMG is not chimeric. In aspects, all of the FMGs are chimeric. In aspects, none of the FMGs are chimeric.

These oligomerizing domains, which can be referred to as “CAPs,” provide a modular solution for enforcing oligomeric arrangements, e.g., a trimeric arrangement that is characteristic of many naturally occurring viral entry proteins. By applying such CAPs to receptor-binding fragments, viral glycoprotein derivatives, or synthetic ligands, the CAPs can restore or replicate the precise geometry important for efficient receptor binding and subsequent membrane fusion events.
[0112] The CAPs are modular, meaning that a CAP may be paired with different receptor-binding domains or ligands. These may include viral receptor-binding fragments, single-chain variable fragments (scFvs) derived from antibodies, nanobodies or Variable Heavy domain of Heavy chain (VHH), peptides, or synthetic ligands engineered to recognize particular cellular receptors.

Trimers of viral FMGs or functional fragments or derivatives thereof, may have one, two, or three targeting domains. The number of targeting domains in the oligomer is the occupancy of the oligomer, wherein the oligomer may have full occupancy (two targeting domains in a dimer or three targeting domains in a trimer), partial occupancy (targeting domains on fewer than all viral FMGs or functional fragments or derivatives thereof of the oligomer, e.g., one targeting domain in a dimer; one or two targeting domains in a trimer), or no occupancy (no targeting domain in the oligomer). In aspects, oligomers of viral FMGs or functional fragments or derivatives thereof having full occupancy or partial occupancy comprise targeting domains with the same identity (i.e., two identical targeting domains or three identical targeting domains). In aspects, oligomers of viral FMGs or functional fragments or derivatives thereof having full occupancy or partial occupancy comprise at least two different targeting domains (e.g., two or three distinct targeting domains).

[0125] The GCN4 leucine / isoleucine zipper peptide has a short a-helical motif enriched in leucines or isoleucines at positions, known as a heptad repeat, which drives trimerization through hydrophobic core formation. As used herein, an oligomerization domain comprising a variant of the GCN4 leucine / isoleucine zipper peptide with systematic substitutions in the a and d positions of the heptad repeat with alanine can be referred to as PEP-AA, systematic substitutions in the a and d positions of the heptad repeat with valine and leucine can be referred to as PEP-VL, and systematic substitutions in the a and d positions of the heptad repeat with isoleucine can be referred to as PEP-II. Previous reports have indicated that the PEP-AA peptide prevents oligomerization, while the PEP-VL and PEP-II peptides induce coiled-coil trimerization. Its extended rod-like geometry can be advantageous when spacing ligands away from a scaffold is necessary.
[0126] The Foldon domain is a short (27 residues) C-terminal motif forming a [3-propeller structure, that can stabilize a trimer through hydrophobic and hydrogen-bond interactions (Meier et al., “Structure and folding of the Foldon domain,” J. Mol. Biol. (2004)). Without wishing to be bound by theory, this 27-amino-acid domain forms a compact [3-propeller-like structure that spontaneously assembles into a stable trimer, where it folds independently of its native fibritin stalk. From a manufacturing standpoint, the Foldon is compatible with a wideLeydig 775202range of expression systems, including bacteria, insect, yeast, and mammalian cells. Its small size minimizes metabolic burden, and it does not require post-translational modifications such as glycosylation or hydroxylation to fold correctly.
[0127] Engineered sequences forming stable triple a-helical bundles typically contain specific amino acids (Leu, He, Vai) strategically placed to ensure stable hydrophobic core interactions. The heptad repeat sequence "IAAIKQE" is a well-characterized motif used in designing trimeric coiled-coil structures to create stable trimeric assemblies (Woolfson, “The design of coiled-coil structures and assemblies,” Adv. Protein Chem. (2005)). As a nonlimiting example, by placing hydrophobic residues in the a and d positions of a heptad repeat, and complementary charged residues in the e and g positions, these designs can achieve high thermal stability and exclusive trimer formation and also be quite flexible.
[0128] The laminin a2 chain C-terminal domain is a 25 -residue segment enabling specific interactions that mediate the formation of a laminin heterotrimer with cx2, [31 , and yl subunits (Utani et al., "Laminin chain assembly: the C-terminal globular domains of the [31 and yl chains direct the specific dimer and trimer assembly," Journal of Biological Chemistry, 269 (30): 19167-19175 (1994)). As a non-limiting example, the present disclosure contemplates a CAP system in which a therapeutic ligand, an immune-modulatory domain, and a stabilizing scaffold are co-assembled in a controlled 1:1:1 ratio. The laminin a2 motif informs the concept that trimerization can involve stabilizing geometry and also selective and functional assembly. For modular CAPs, this means that one can move beyond generic trimerization toward programmable trimerization, where only designated chains are incorporated. This could be used, for example, to construct viral vectors where targeting ligands are selectively paired with stabilizing domains, and / or where multiple receptor-binding specificities are encoded in a defined stoichiometry.
[0129] The collagen triple helix motif comprises a repeating Gly-X-Y sequence, where X and Y are often proline or hydroxyproline that forms tightly wound triple helices stabilized by hydrogen bonds (Bella et al. “Crystal and molecular structure of a collagen-like peptide at 1.9 A resolution,” Science (1994)). This structure can be stable, resistant to proteolysis, and / or mechanically robust.
[0130] Peptides such as QQRFEWEFEQQ (SEQ ID NO: 84) spontaneously form [3-sheet structures stabilized by hydrogen bonding, enabling stable self-assembly into trimers or other oligomers (Aggeli et al., “Responsive gels formed by the spontaneous self-assembly of peptides into polymeric [3-sheet tapes,” Nature, 386(6622): 259-262 (1997)). Without wishing to be bound by theory, these achieve multimerization through [3-sheet formation,Leydig 775202spontaneously forming tapes and fibrils stabilized by hydrogen bonding and aromatic interactions. Design can bias these toward trimeric arrangements when the bias is otherwise non-trimeric. These can exhibit resistance to proteolysis and / or environmental stress.
[0131] A coiled-coil heptad repeat region in the HA2 subunit is important for trimer formation, stability, and function of influenza hemagglutinin. The HA2 subunit's coiled-coil is formed by a continuous a-helical region, but the exact sequence may vary among different influenza A strains (Wilson et al., “Structure of the hemagglutinin membrane glycoprotein of influenza virus at 3 A resolution,” Nature (1981)).
[0132] The NCI domain contains intrinsic trimeric domains known to drive stable trimer formation. The collagen XVIII NCI trimerization domain nucleates trimer formation of collagen XVIII and is stabilized by a combination of hydrophobic interactions and hydrogen bonds. Structural analysis reveals a three-bladed propeller-like architecture. It is stable and tolerant of fusion partners. Because it is distinct from viral sequences, it may also present fewer immunogenicity problems.
[0133] These oligomerization domains collectively illustrate various sequences by which recombinant proteins can reliably form stable oligomers, including trimers.

Rhabdoviruses are viruses within the family Rhabdoviridcie . The viruses encode proteins denoted N (nucleoprotein), P (phosphoprotein), M (matrix protein), G (glycoprotein), and L (large protein, which is a polymerase), and the viruses appear to have a shape of a bullet when observed using electron microscopy.

[0135] Rhabdoviral G glycoprotein mediates binding of rhabdovirus to a receptor on a cell, which binding then mediates entry of the rhabdovirus into the cell and infection of the cell. A rhabdoviral G glycoprotein or functional fragment or derivative thereof as described herein can be used to pseudotype a type of virus or virus-like particle that is not the native / natural virus of the rhabdoviral G glycoprotein.
[0136] As used herein, a “pseudotype” of a virus, virus-like particle, membraned vesicle, enveloped delivery vehicle, enveloped viral particle, or recombinant viral vector, etc. means a virus, membraned vesicle, enveloped delivery vehicle, enveloped viral particle, or recombinant viral vector, etc. comprising a molecule, e.g., a FMG or functional fragment or derivative thereof, such as a rhabdoviral G glycoprotein or functional fragment or derivative thereof, that is not typically found in the virus, membraned vesicle, enveloped delivery vehicle, enveloped viral particle, or recombinant viral vector, etc. Such a molecule can have a mutation (e.g., a substitution or deletion) that impacts the tropism of the virus, membraned vesicle, enveloped delivery vehicle, enveloped viral particle, or recombinant viral vector, etc. The impact on tropism can be, e.g., to contribute to, direct, redirect, or completely change, or any combination thereof, the tropism of the virus, virus-like particle, membraned vesicle, enveloped delivery vehicle, enveloped viral particle, or recombinant viral vector, etc. when compared to the virus, membraned vesicle, enveloped delivery vehicle, enveloped viral particle, or recombinant viral vector, etc. without the molecule and / or compared to the wildtype virus, virus-like particle, membraned vesicle, enveloped delivery vehicle, enveloped viral particle, or recombinant viral vector, etc. The impact on tropism can be, e.g., to target a cell that is different from the cell normally targeted by the virus, virus-like particle, membraned vesicle, enveloped delivery vehicle, enveloped viral particle, or recombinant viral vector, etc. and / or to not target a cell that is normally targeted by the virus, virus-like particle, membraned vesicle, enveloped delivery vehicle, enveloped viral particle, or recombinant viral vector, etc.
[0137] As used herein, “functional fragment” of a rhabdoviral G glycoprotein means a rhabdoviral G glycoprotein that is not a full length rhabdoviral G glycoprotein but is a portion of a parent rhabdoviral G glycoprotein (e.g., a truncated form of a full length rhabdoviral G glycoprotein), where the portion retains the fusion function of the parent full lengthLeydig 775202rhabdoviral G glycoprotein. As used herein, “functional derivative” or “functional variant” of a rhabdoviral G glycoprotein means a rhabdoviral G glycoprotein that has been modified, e.g., by conservative amino acid substitution, where the rhabdoviral G glycoprotein retains the fusion function of the parent full length rhabdoviral G glycoprotein. As used herein, “functional fragment or derivative” and “functional fragment or variant” encompass the meanings of both “functional fragment” and “functional derivative” / “functional variant.” The “fusion function” of a rhabdoviral G glycoprotein means that a rhabdoviral G glycoprotein, when part of a virus, can initiate fusion of the virus with a target cell, e.g., such that the virus can infect the target cell. Such fusion can be due to the interaction of the rhabdoviral G glycoprotein with its natural receptor or the interaction of the rhabdoviral G glycoprotein with a different receptor (e.g., the rhabdoviral G glycoprotein is blinded to its natural receptor, such that the rhabdoviral G glycoprotein is engineered to reduce or abolish its natural receptor binding specificity, and the rhabdoviral G glycoprotein is re-targeted to a new receptor). A functional fragment and / or functional derivative / fimctional variant of a rhabdoviral G glycoprotein can be within a recombinant fusion protein.
[0138] In aspects, the rhabdoviral G glycoprotein or functional fragment or derivative thereof is of a Vesiculovirus glycoprotein or a functional fragment or derivative thereof. In aspects, the rhabdoviral G glycoprotein or functional fragment or derivative thereof is of Vesiculovirus Indiana, Vesiculovirus new jersey, Vesiculovirus carajas, or Vesiculovirus alagoas.

In aspects, the rhabdoviral G glycoprotein or functional fragment or derivative thereof contains one or more conservative amino acid substitutions that do not interfere with the fusion function of the rhabdoviral G glycoprotein or functional fragment or derivative thereof.
[0139] Vesicular stomatitis virus (VSV) is a rhabdovirus, having a natural receptor of the low-density lipoprotein receptor (LDL-R) or very low-density lipoprotein receptor (VLDL-R), which are expressed on the cell membrane of many types of cells. As used herein, the term “receptor blinded” refers to a FMG with reduced or abolished binding specificity for a natural receptor. A FMG or functional fragment or derivative thereof described herein canLeydig 775202have increased or decreased fusion efficiency compared to a wild type FMG. Increase in fusion efficiency specificity can be of any amount, e.g., increased by 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 200%, 500%, 1000%, or any range between these percentages. Decrease in fusion efficiency can be of any amount, e.g., decreased by 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20%, 10%, 5%, 2%, 1%, or any range between these percentages.
[0140] In aspects, the rhabdoviral G glycoprotein is engineered to reduce or abolish its natural receptor binding specificity. In aspects, the rhabdoviral G glycoprotein is engineered to have a mutation to reduce or abolish its natural receptor binding specificity. In aspects, the rhabdoviral G glycoprotein comprises a mutation at one or more positions corresponding to H8, K47, Y209, and K354 on the Vesiculovirus Indiana glycoprotein (SEQ ID NO: 1). In aspects, the mutation is a substitution. In aspects, the substitution is with a Q. In aspects, the mutation is a substitution at two or more positions. In aspects, the mutation is a deletion. In aspects, the mutation is a single deletion at the position corresponding to K47 on the Vesiculovirus Indiana glycoprotein (SEQ ID NO: 1). It has been found that a Vesiculovirus Indiana rhabdoviral G glycoprotein having a deletion of K47 reduces or abolishes the natural receptor binding specificity of the rhabdoviral G glycoprotein when the rhabdoviral G glycoprotein while unexpectedly retaining full function of the G protein in other respects. In particular, this feature is seen when incorporated into a lentiviral vector. However, when used in a VSV vector, there is second site mutation (F405I) generated in the VSV-G protein during the virus amplification. This mutation leads to the loss of detargeting effect caused by the deletion on K47 residue. In aspects, the rhabdoviral G glycoprotein comprises a mutation at one or more positions corresponding to H8, K47, Y209, and K354 on the Vesiculovirus New Jersey glycoprotein (SEQ ID NO: 2). In aspects, the mutation is a substitution. In aspects, the substitution is with a Q. In aspects, the mutation is a substitution at two or more positions. In aspects, the mutation is a deletion. In aspects, the mutation is a single deletion at the position corresponding to K47 on the Vesiculovirus New Jersey glycoprotein (SEQ ID NO: 2). It has been found that a Vesiculovirus New Jersey rhabdoviral G glycoprotein having a deletion of K47 reduces or abolishes the natural receptor binding specificity of the rhabdoviral G glycoprotein when the rhabdoviral G glycoprotein while unexpectedly retaining full function of the G protein in other respects. Without wishing to be bound by theory, this phenomenon may be due to VSV being a replicating virus, whereas lentivirus, like VLPs, is nonreplicating.Leydig 775202
[0141] In aspects, the rhabdoviral G glycoprotein or functional fragment or derivative thereof is of a Kumasi virus glycoprotein (KRV-G). In aspects, the rhabdoviral G glycoprotein or functional fragment or derivative thereof is of KRV glycoprotein (SEQ ID NO: 43) and is engineered to have a mutation to reduce or abolish its natural receptor binding specificity wherein the mutation comprises a mutation at one or more positions corresponding to E22, R194, R209, E294, E298, K358, and D371 of SEQ ID NO: 43. In aspects, the mutation is a deletion. In aspects, the mutation is a single deletion at the position corresponding to R194 on the KRV glycoprotein (SEQ ID NO: 43).
[0142] Amino acid positions of other rhabdoviral G glycoproteins or functional fragments or derivatives thereof that are “positions corresponding to” the amino acids discussed above can be determined using a global sequence alignment algorithm (see, e.g., Madeira et al., Nuc. Acids Res., 50(Wl): W276-W279 (2022), which is incorporated herein by reference in its entirety) comparing the base rhabdoviral G glycoprotein to another rhabdoviral G glycoprotein.
[0143] In aspects, the rhabdoviral G glycoprotein is substantially intact; in other aspects, the rhabdoviral G glycoprotein is a functional fragment or derivative thereof. As used herein, a “substantially intact” rhabdoviral G glycoprotein means a rhabdoviral G glycoprotein that is a functional fragment of the rhabdoviral G glycoprotein, where the rhabdoviral G glycoprotein has each of the domains of a rhabdoviral G glycoprotein, the domains as defined in Roche et al., Cell. Mol. Life Sci., 65: 1716-1728 (2008), which is incorporated herein by reference in its entirety. In aspects, the cytoplasmic tail of the glycoprotein is truncated, deleted, or replaced with another sequence. Previous work has shown that such truncation or deletion can enhance fusion activity in rhabdoviral G glycoprotein. In aspects, the truncations from the C terminus can be, for example, 1 amino acid, 2 amino acids, 3 amino acids, 4 amino acids, 5 amino acids, 6 amino acids, 7 amino acids, 8 amino acids, 9 amino acids, 10 amino acids, 20 amino acids, 30 amino acids, 40 amino acids, 50 amino acids, 60 amino acids, up to 10 amino acids, up to 20 amino acids, up to 30 amino acids, up to 40 amino acids, up to 50 amino acids, up to 60 amino acids, or more than 60 amino acids. In aspects, the cytoplasmic tail is replaced with another sequence.
[0144] Rhabdoviral G glycoproteins can associate into trimers at the surface of a native virus, an EDV as described herein, or a viral vector as described herein. As used herein, a “mixed rhabdoviral G glycoprotein trimer” comprises, consists essentially of, or consists of three rhabdoviral G glycoproteins or functional fragments or derivatives thereof (wherein each is optionally within a recombinant fusion protein), wherein (a) at least one of theLeydig 775202rhabdoviral G glycoproteins or functional fragments or derivatives thereof in the trimer is within a recombinant fusion protein comprising, consisting essentially of, or consisting of a rhabdoviral G glycoprotein or a functional fragment or derivative thereof engineered to reduce or abolish natural receptor binding specificity and a polypeptide antibody construct, wherein the polypeptide antibody construct has the capability to bind to human CD3, and (b) at least one of the rhabdoviral G glycoproteins or functional fragments or derivatives thereof in the trimer is not within a recombinant fusion protein and does not have a polypeptide antibody construct.
[0145] In aspects, the rhabdoviral G glycoprotein or functional fragment or derivative thereof is within a fusion protein that comprises a targeting molecule.
[0146] Trimers of rhabdoviral G glycoproteins or functional fragments or derivatives thereof, may have one, two, or three targeting molecules. The number of targeting molecules in the trimer is the occupancy of the trimer, wherein the trimer may have full occupancy (three targeting molecules in the trimer), partial occupancy (targeting molecules on fewer than all rhabdoviral G glycoproteins or functional fragments or derivatives thereof of the trimer, e.g., two or one targeting molecules), or no occupancy (no targeting molecule in the trimer). In aspects, trimers of rhabdoviral G glycoproteins or functional fragments or derivatives thereof having full occupancy or partial occupancy comprise targeting molecules with the same identity (i.e., two identical targeting molecules or three identical targeting molecules). In aspects, trimers of rhabdoviral G glycoproteins or functional fragments or derivatives thereof having full occupancy or partial occupancy comprise at least two different targeting molecules (e.g., three distinct targeting molecules).
[0147] As used herein, the term “targeting molecule” refers to a binding moiety (that can bind or that can be bound), such as a natural ligand, antibody, multispecific binding molecule, or others known in the art. Any suitable targeting molecules can be used. “Targeting molecule” and “targeting domain” are used interchangeably herein.
[0148] The targeting molecule can target any suitable cell type. In aspects, a targeting molecule specifically binds a cell surface molecule, e.g., specifically binds a cell surface molecule, e.g., an oligosaccharide, a receptor, cell surface marker, etc., expressed on the surface of a mammalian (e.g., human) eukaryotic cell. In aspects, a targeting domain binds a (e.g., human) liver cell, a (e.g., human) brain cell, a (e.g., human) T cell, a (e.g., human) kidney cell, a (e.g., human) intestinal cell, a (e.g., human) lung cell, a (e.g., human) cancerous cell, or a (e.g., human) cell infected with heterologous pathogen. Exemplary cell types targeted by targeting molecules considered herein include, but are not limited to,Leydig 775202hematopoietic stem cells (HSC), hematopoietic progenitor cells (HPC), T cells, monocytes, NK cells, and macrophages. For HSC, non-limiting examples of markers that can be targeted by the targeting molecule include, e.g., one or more of CD34, CD46, CD90 (Thy-1), CD133, CD135 (Flt3) and CD201 (EPCR). For T cells, non-limiting examples of markers that can be targeted by the targeting molecule include, e.g., one or more of TRBC1, CD3, CD4, CD5, CD7, CD8, CD30, T cell receptor (TCR), thrombopoietin receptor (TPO-R), which is also known as cMpl, cKit receptor, which is also known as CD117, etc. For monocytes, nonlimiting examples of markers that can be targeted by the targeting molecule include, e.g., one ormore of CD14, CDllb, CD33, CD47, CD123 (IL-3Ra), CD116 / CD131, and CSF1R. For NK cells, non-limiting examples of markers that can be targeted by the targeting molecule include, e.g., one or more of B7-H6, CS1(SLAMF7), CD16 (FcyRIIIa), CD56, and NKG2D.
[0149] As used herein, “hematopoietic stem cell” or “HSC” refers to a multipotent primitive cell with the capability to self-renew and develop into all types of blood cells, including myeloid-lineage and lymphoid-lineage cells. HSCs may be categorized as longterm or short-term HSCs. As used herein, “long-term HSC” or “LT-HSC” refers to a hematopoietic stem cell characterized by its ability to self-renew and differentiate into various blood cell types over extended periods, typically months to years. A small percentage of blood cells are LT-HSCs, which are typically the target cells for gene editing. In mice LT-HSCs are typically CD34 negative (CD34-) (Matsuoka et al., “CD34 expression on long-term repopulating hematopoietic stem cells changes during developmental stages,” Blood, 97(2): 419-425 (2001)). In humans LT-HSCs are typically CD34 positive (CD34+), although a population of CD34- LT-HSCs have been identified in human hematopoietic tissue, including bone marrow (Hughes et al., “A sticky wicket: Defining molecular functions for CD34 in hematopoietic cells,” Experimental Hematology, 86: 1-14 (2020)). Human LT-HSCs can be CD34+ CD38- CD90+ Lin- (CD34 plus, CD38 minus, CD90 plus, Lin minus) cells. As used herein, “short-term HSC” or “ST-HSC” refers to a stem cell distinguished by its relatively limited self-renewal capacity and more immediate differentiation into specialized cell types, typically weeks to months. In aspects, the HSC is a long-term HSC.
[0150] As used herein, “hematopoietic progenitor cell” or “HPC” refers to a multipotent, oligopotent, or unipotent cell lacking significant self-renewal capacity but capable of differentiating further into mature blood cells of all hematopoietic lineages. As used herein, “hematopoietic stem and progenitor cell” or “HSPC” is a term that encompasses both HSCs and HPCs.Leydig 775202
[0151] As used herein, “T cell” is a term that encompasses both resting or quiescent T cells and activated T cells. Both resting and activated T cells are known to express CD3. The activation of T cells typically requires a T cell to experience at least two signals referred to herein as signal 1 and signal 2. Binding CD3-TCR complex provides the first signal which leads to T cells activation and involves signal transduction via CD3 subunit cytoplasmic tails which contain ITAMs (10 ITAMs per TCR). Activation of a T cell is determined by engagement of a specific, yet unknown, number of ITAMs (but not all 10 ITAMs) found distributed across all the CD3 subunits. The involvement of different ITAMs make CD3 signaling tunable. The proper activation of T cells which resulted in cytolytic activity usually requires signal 2 from co-stimulatory molecules and in some conditions a signal 3 provided by cytokines.

In aspects, producing vectors as described herein in a cell that expresses CD55 (or overexpresses CD55) can increase resistance to complement inactivation.
[0158] In aspects, the present disclosure provides a vector production system wherein the vector production system is a retroviral vector expression system and wherein the retroviral vector expression system is a lentiviral vector expression system. In aspects, the present disclosure provides a vector production system wherein the vector production system is a retroviral vector expression system and wherein the retroviral vector expression system is a Rous sarcoma virus (RSV) vector expression system. In aspects, the present disclosure provides a vector production system wherein the vector production system is a retroviral vector expression system and wherein the retroviral vector expression system is a murine leukemia virus (MLV) vector expression system.
[0159] As used herein, “lentiviral vector” refers to a viral vector derived from lentivirus, such as the human immunodeficiency virus (HIV). Lentiviral vectors (LVs) are modified retroviruses capable of stably integrating into the host genome. This integration can drive long-term transgene expression, making LVs particularly attractive for conditions requiring chronic, ongoing production of a therapeutic protein, or for maintaining CRISPR-Cas components where repeated or prolonged activity is needed. However, LV integration raises concerns about insertional mutagenesis and potential oncogenic events, especially when delivered at high copy numbers or to cells highly susceptible to transformation. Furthermore, lentiviruses can elicit immune responses, including responses to viral proteins and the risk of transgene immunogenicity.
[0160] Rous sarcoma virus (RSV) is an alpharetrovirus and member of the family Retroviridae . RSV has an RNA genome that encodes gag, pol. and env genes that are translated to Gag, Gag-Pol, and Env polyproteins. The RSV Gag polyprotein can be cleaved to form a matrix protein (MA), a p2a protein, a p2b protein, a plO protein, capsid protein (CA), a spacer peptide, a nucleocapsid protein (NC), and a p 15 protease protein (PR). The RSV Gag proteins are capable of self-assembly into VLPs. The RSV Pol polyprotein can be cleaved to form a reverse transcriptase protein (RT) and an integrase protein (IN). Any suitable RSV strain can be used in the context of the present disclosure.Leydig 775202
[0161] Notably, RSV lacks certain lentiviral regulatory genes such as Tat and Rev, allowing for development of particle systems that avoid incorporating such regulatory proteins. Additionally, while other viruses used to generate VLPs, such as the lentiviral HIV-1 and the gammaretroviral murine leukemia virus (MLV), have mammalian hosts, the RSV has an avian host. Therefore, the avian nature of the host of RSV reduces the likelihood of off target infection of RSV VLPs in mammals, compared to VLPs derived from HIV-1 or MLV.
[0162] In aspects, the present disclosure provides a producer cell comprising a retroviral expression system disclosed herein. Any suitable producer cell for producing an enveloped delivery vehicle or viral vector is contemplated in the present disclosure, e.g. HEK293 cells.
[0163] In aspects, the present disclosure provides an enveloped delivery vehicle (EDV) produced by a producer cell transduced or transfected with the retroviral expression system disclosed herein.
[0164] As used herein, a “membraned vesicle” is a vesicle bound (delimited) by a lipid bilayer membrane. In aspects, the membraned vesicle is either naturally-derived or engineered. A membraned vesicle can be cell-derived and thus be a cell-derived enveloped particle (CDEP).
[0165] In aspects, a membraned vesicle is a gesicle or an exosome. A gesicle can be as described in Mangeot et al., Mol. Ther., 19: 1656-1666 (2011), which is incorporated herein by reference in its entirety, where overexpression of glycoprotein of VSV-G in human cells induced release of fusogenic vesicles. As used herein, an “exosome” refers to a lipid bilayer vesicle ranging in size from approximately 30 nm to 150 nm in diameter, secreted by eukaryotic cells via the endosomal pathway, and often containing biologically active molecules such as proteins, lipids, RNA, or DNA. An exosome typically originates from multi vesicular bodies (MVBs) and is released into the extracellular environment through exocytosis. Exosomes are known to serve as intercellular communication vehicles and may be utilized for diagnostic, therapeutic, or drug delivery applications. Examples of exosomes are provided in Li et al., European Journal of Medicinal Chemistry 207: 112784 (2020); Yang et al., Adv. Mater. 29: 1605604 (2017); U.S. Pat. No. 10,195,290; and U.S. Patent Application Publication No. 2018 / 0028600, each of which is incorporated herein by reference in its entirety.
[0166] As used herein, an “enveloped viral particle” is a vesicle bound (delimited) by a lipid bilayer membrane and has the ability to infect a cell and produce additional enveloped viral particles. An enveloped viral particle can include one or more components of a virus, e.g., a rhabdoviral G glycoprotein or functional fragment or derivative thereof or recombinantLeydig 775202fusion protein thereof. Exemplary components of a virus include, without limitation, the gag, pol, or env gene or gene product of lentivirus.
[0167] A “virus-like particle” (VLP) as used herein means an enveloped viral particle that cannot produce additional virus-like particles (i.e., is replication-incompetent). Virus-like particles (VLPs) are non-infectious and mimic the conformation of their parental viruses but lack the viral genetic material required for replication. A VLP can contain genetic materials / nucleic acid not associated with self-replication. VLPs can preserve the high packaging efficiency and target-specificity of certain viruses while greatly minimizing the risk of host genome integration. Because VLPs do not replicate or integrate into the host genome, they are often associated with lower cytotoxicity and reduced immunogenic risk compared to replication-competent viral systems.
[0168] In aspects, membraned vesicles, cell-derived enveloped particles, enveloped viral particles, and virus-like particles can encapsulate cargo / payload, e.g., proteins, lipids, nucleic acids, etc. for delivery, such that membraned vesicles, cell-derived enveloped particles, enveloped viral particles, and virus-like particles can be considered “enveloped delivery vehicles” (EDVs).
[0169] Lentiviral particles (LVPs) are replication incompetent EDVs derived from lentiviral HIV-1 and produced by producer or packaging cells such as HEK293. Lentiviral particles are capable of transducing both dividing and non-dividing cells.
[0170] In aspects, the present disclosure provides a viral vector produced by a producer cell transduced or transfected with the retroviral expression system disclosed herein. In keeping with this aspect, the viral vector may be any suitable viral vector capable of delivering and integrating genetic material into the genome of a target cell.

In aspects, the EDV or viral vector described herein for use in the treatment of cancer are administered as a composition as described herein, comprising a FMG or functional fragment or derivative thereof or recombinant protein thereof, and subsequently administered as a composition as described herein, comprising a different FMG or functional fragment or derivative thereof or recombinant protein thereof. The subsequent administration may be within hours, days, months, or years of the first administration, with scheduling to be determined by patient needs. Multiple rounds of subsequent administrations may be performed, using the same or different FMGs as determined by the patient needs. Without wishing to be bound by theory, it is believed that administering a different FMG or functional fragment or derivative thereof reduces the likelihood of decreased effectiveness due to any immune response that is directed against the first FMG or functional fragment or derivative thereof. A FMG or functional fragment or derivative thereof or recombinant protein thereof described herein can be the first administered, and a FMG or functional fragment or derivative thereof or recombinant protein thereof as described herein that has a different FMG than the first FMG or functional fragment or derivative thereof or recombinant protein thereof can be the subsequently administered FMG or functional fragment or derivative thereof or recombinant protein thereof. This sequence of events can be termed “re-dosing”.
[0176] As used herein, “treatment” or “treat” refers to a therapeutic intervention that ameliorates a sign or symptom of a disease or pathological condition after it has begun to develop, and also includes addressing a medical condition or disease with the objective of improving or stabilizing an outcome in a mammal being treated. “Treating,” “treat,” and “treatment” have grammatically corresponding meanings. In the context of cancer, the termsLeydig 775202“treat” or “treating” or “treatment” can, among other things, refer to inducing apoptosis of cancerous cells, reducing the size of a cancerous tumor, delaying the growth of tumors, or inducing or enhancing an immune response against one or more cancerous cells, where the immune response has the effect of inducing apoptosis, reducing the size of a tumor, or the like. The terms “treat,” “treating,” “treatment,” “therapeutically effective,” “prevention,” etc. used herein do not necessarily imply 100% or complete treatment / prevention / etc. Rather, there are varying degrees, which one of ordinary skill in the art recognizes as having a potential benefit or therapeutic effect. In this respect, the membraned vesicles, enveloped viral particles, recombinant viral vectors, etc. as described herein and methods as described herein can provide any amount of any level of treatment. Furthermore, the treatment provided by the disclosed method can include the treatment of one or more conditions or symptoms of the disease or condition being treated. In aspects, the tumor size is reduced in the mammal.
[0177] In aspects, the present disclosure provides a method of enhancing immunological cell response in a mammal, the method comprising administering to a mammal in need thereof an effective amount of the pharmaceutical composition of claim 120, wherein an immunological cell comprising CAR with antigenic specificity for an antigen expressed on a B cell is generated in vivo, and wherein the immunological cell response is greater than for an immunological cell that does not comprise a CAR with antigenic specificity for an antigen expressed on a B cell. In aspects, the immunological cell is a T cell. In aspects, the enhanced immunological response comprises T cell activation, T cell expansion, T cell persistence, or any combination thereof. In aspects, activation of the immunological cell results in secondary effects that contribute to elimination of antigen-negative tumor cells, including recruitment or activation of endogenous immune cells.
[0178] As used herein, “immunological cell” refers to a specialized type of cell involved in the immune response of a mammal. Immunological cells include, but are not limited to, lymphocytes / lymphoid cells (such as T cells, B cells, and natural killer (NK) cells), dendritic cells, macrophages, and granulocytes. As used herein, “natural killer cell” or “NK cell” refers to a type of lymphocyte that plays a role in the innate immune system defense against viral infections and tumor formation. NK cells are characterized by their ability to recognize and kill abnormal cells without prior sensitization.
[0179] The immunological cells of the present disclosure can be prepared using any suitable method known in the art. For example, In aspects, to generate autologous CAR-T cells, peripheral blood mononuclear cells (PBMC) are harvested from the bloodstream, T cells are sorted from the mixed PBMC population and at the same time activated using beadsLeydig 775202coated with antibodies to CD3 and CD28 that bind to CD3 and CD28 on the T cells, the activated T cells are transduced with a retroviral vector encoding the CAR construct and then, following appropriate “release testing,” are reinfused.
[0180] In aspects, the present disclosure provides a method of producing a population of immunological cells, the method comprising contacting the population of immunological cells with the pharmaceutical composition disclosed herein.

In aspects, the population of immunological cells are produced in vivo. In aspects, the population of immunological cells are produced ex vivo.
[0182] Direct in vivo genetic modification of immune effector cells represents an alternative paradigm to ex vivo manipulation. In vivo programming enables immune effector cells to be genetically modified within the physiological environment of the subject, including within peripheral blood, lymphoid tissues, or tumor-draining lymph nodes. This approach may facilitate the genetic programming of immune effector cells that naturally traffic to tumor sites, enable modification of tissue-resident or tumor-infiltrating lymphocytes, and permit ongoing generation of newly programmed effector cells over time. In addition, in vivo modification may allow genetic programming to occur within anatomical compartments that are relevant to the initiation and maintenance of anti-tumor immune responses.
[0183] The use of EDVs and viral vectors for in vivo delivery of nucleic acids encoding CAR constructs provides a platform for stable genetic modification of immune effector cells within a subject. In the context of solid tumors, in vivo generation of CAR-expressing immune effector cells may provide biological advantages, including programming of immune cells within tumor-draining lymph nodes, engagement of endogenous immune priming pathways, continuous replenishment of effector populations, and the potential for spatially distributed generation of engineered cells across relevant anatomical compartments.Leydig 775202Additionally, in vivo programming may permit immune effector cells to undergo activation, expansion, and differentiation in response to antigen exposure within the tumor microenvironment.

[0341] It shall be noted that the preceding are merely examples of aspects of the disclosure. Other exemplary aspects are apparent from the entirety of the description herein. It will also be understood by one of ordinary skill in the art that each of these aspects may be used in various combinations with the other aspects provided herein.
[0342] The following examples further illustrate the disclosure but, of course, should not be construed as in any way limiting its scope.EXAMPLE 1
[0343] This example demonstrated that lentiviruses packaged with a solid tumor targeting DLL3 CAR transgene were able to successfully transduce Jurkat cells and T cells andLeydig 775202generated functional DLL3 CARs as determined by increased CD69 expression and CAR-T killing assay.
[0344] To test the efficacy of lenti viruses containing a solid tumor targeting DLL3 CAR transgene to successfully transduce Jurkat cells, lentiviruses were packaged with constructs of a 5’ EFla promoter (SEQ ID NO: 12), CD8 signal peptide (SP) (SEQ ID NO: 13), DLL3 binding domain, CD28 hinge domain (SEQ ID NO: 14) and transmembrane (TM) domain (SEQ ID NO: 15), 4-1BB co-stimulatory domain (SEQ ID NO: 16), CD3 zeta signaling domain (SEQ ID NO: 17), p2A (SEQ ID NO: 18), and a GFP (SEQ ID NO: 19), as shown in FIG. 2. The DLL3 binding domain of the DLL3-LB CAR construct (VHH97 80 FLAG) (SEQ ID NO: 24), had two nanobodies (SEQ ID NOS: 20 and 21); linked by a (G4S)x3 linker sequence (SEQ ID NO: 48) while the DLL3 binding domain of the DLL3-T CAR construct (FLAG-T) (SEQ ID NO: 25) had a heavy (SEQ ID NO: 22) and light chain (SEQ ID NO: 23) scFv linked by a (G4S)x3 linker sequence (SEQ ID NO: 48). The constructs each had a 3xFLAG tag (SEQ ID NO: 10) located 3’ of the DLL3 binding domain in the DLL3-LB CAR and located 5’ of the DLL3 binding domain in the DLL3-T CAR. A construct of EFla promoter and GFP (SEQ ID NO: 26) was used as a negative control.
[0345] Second generation lentivirus was packaged with the constructs and wild type VSV G glycoprotein constructs in adherent HEK 293T cells and transfection efficiency was determined by GFP expression. p24 ELISA / mL values were determined by analytical using a p24 DUOSET™ ELISA kit, as shown in Table 2.Table 2Sample Name p24 ELISA / mLGFP 3.05E+10DLL3-LB 1.24E+10DLL3-T 2.10E+10
[0346] To determine if the lentiviruses containing the DLL3 CAR constructs could successfully transduce Jurkat cells and express functional DLL3 CARs a CAR-J assay was performed as shown in FIG. 3. Jurkat cells were transduced with lentivirus containing the DLL3-LB or DLL3-T CAR construct at a concentration of 500 lentivirus particles (LVPs) per cell. Two days after transduction Jurkat cells underwent flow cytometry to detect GFP expression, DLL3 expression, and FLAG tag express to quantify the transduction. Additional antibodies were used during flow cytometry, as shown in Table 3, to gate Jurkat cells (CD3 and CD5) and measure CD69 expression as an indicator of DLL3 binding. CD69 is anLeydig 775202activation marker, so increased CD69 express indicates that the DLL3 CARs are recognizing their antigen DLL3 and activating the transduced cell.Table 3Fluorophore usedAntibody Namefor Detectiona-CD3 (UCHT1) BV605a-CD5 AF700a-CD69 BV421a-DLL3 binders AF647a-FLAG tag PE-Cy7a-Live / Dead 780 APC-Cy7GFP FITC
[0347] Jurkat cells transduced with lentiviruses packaged with the GFP control construct showed expression of GFP but not FLAG tag or DLL3 (FIG. 4A). The flow cytometry data for the Jurkat cells transduced with DLL3-LB CAR and DLL3-T CAR both showed high expression of DLL3, but relatively low expression of FLAG tag (FIG. 4B). The low level of detected FLAG tag could have been caused by an inability to detect the FLAG tag with the FLAG tag antibody.
[0348] To determine if the DLL3 CARs were functional, two days after the Jurkat cells were transduced with the lentiviruses packaged with DLL3-LB CAR and DLL3-T CAR, the transduced Jurkat cells were transferred onto HelaHl cells, and HelaHl cells expressing human DLL3 (HelaHl-huDLL3) (FIGS. 6A-6B). This experiment was repeated with the transduced Jurkat cells transferred onto endogenous DLL3 expressing cell lines NCI-H69, NCI-H82, NCI-H146, and SHP-77 (FIGS. 7A-7B). One day after coculture, cells were collected for flow cytometry to measure CD69 expression as an indicator of DLL3 CAR J activation upon DLL3 binding in CD3+ CD5+ Jurkat cells. The level of DLL3 expression for each of these cell lines was quantified by whole-cell protein expression western blot using anti-huDLL3 antibody and anti-vinculin antibody as a control (FIG. 5A) and flow cytometry measuring surface expression of DLL3 (FIGS. 5B-5C). These results were quantified as S / N ratio and relative DLL3 expression was determined as shown in Table 4.Leydig 775202Table 4Relative DLL3Cell Line Expression (measure byflow cytometry)Jurkat Background / negligibleHeLaHl Background / negligibleHeLaHl-huDLL3 Moderate expressionNCI-H69 Low expressionNCI-H82 Moderate expressionNCI-H146 Moderate expressionSHP-77 High expression
[0349] None of the cells treated with Jurkat cells transduced with the control GFP construct showed any CD69 expression. The Jurkat cells transduced with the DLL3-LB CAR and DLL3-T CAR and cocultured with cells having negligible DLL3 expression, Jurkat and HelaHl cells, showed very low levels of CD69 expression, detectable in only about 3% of the transduced Jurkat cells (FIG. 6A). The Jurkat cells transduced with the DLL3-LB CAR and DLL3-T CAR and transferred to cells with low, moderate, or high DLL3 expression, HelaHl-huDLL3, NCI-H69, NCI-H82, NCI-H146, and SHP-77 cells, showed high levels of CD69 expression, detectable in about 12-53% of the transduced Jurkat cells (FIGS. 6B, 7A, and 7B).
[0350] Next, to determine the efficacy of the lentiviruses packaged with DLL3 CAR constructs to transduce human lymphocytes, human peripheral blood mononuclear cells (PBMCs) were transduced with lentiviruses packaged with the DLL3 CAR constructs. The human PBMCs were thawed and activated using CD3 / CD28 activation beads. Two days later the activated PBMCs were transduced with 500 LVPs per cell packaged with the GFP control, DLL3-LB CAR construct, or DLL3-T CAR construct. Five days after transduction the PBMCs underwent flow cytometry to detect GFP and DLL3 CAR expression in CD3+ primary lymphocytes (FIG. 8). The PBMCs that underwent mock treatment and transduced by the lentivirus packaged with the GFP control construct showed no DLL3 CAR expression, while the PBMCs transduced with the lentivirus packaged with the DLL3-LB and DLL3-T constructs showed expression of DLL3 CAR -in about 17-20% of the CD3+ primary lymphocytes.
[0351] To determine the best ratio of effector cells, i.e., DLL3 CAR transduced PBMCs, to target cells, i.e., cells expressing DLL3, for killing target cells, effector to target ratios (E:T) of between 0: 1 and 8:1 were tested. The human PBMCs were thawed and activatedLeydig 775202using CD3 / CD28 activation beads. Two days later the activated PBMCs were transduced with 500 LVPs per cell packaged with GFP control, DLL3-LB CAR construct, or DLL3-T CAR construct. Five days after transduction the PBMCs underwent flow cytometry to detect GFP and DLL3 expression in CD3+ primary lymphocytes. Then the growth and proliferation supplements (IL-2 and activation beads, were removed from culture and the transduced PBMCs were cocultured at E:T ratios of 0.125: 1, 0.25: 1, 0.5: 1, 1: 1, 2: 1, 4:1, and 8: 1 to HelaHl-huDLL3 luciferase expressing cells. The next day, luciferin substrate was added to each condition and relative luciferase (RLU) values were read out on the MAGELLAN TECAN™ instrument for each sample and the percentage of viable target cells was calculated (FIG. 9). The PBMCs from the mock treatment and transduced with the GFP control did not kill DLL3 expressing cells at any of the tested E:T ratios. The PBMCs transduced with DLL3-LB and DLL3-T CAR were able to kill target DLL3 expressing cells at E:T ratios of 1 : 1, 2: 1, 4: 1, and 8:1, with the best results at an E:T ratio of 8: 1 killing over 60% of target cells.
[0352] To determine the strength of the DLL3 targeting CARs a proliferation assay was performed to measure the T cell expansion after each restimulation as shown in FIG. 10. Target cells, HelaHl-huDLL3 mitomycin C (MMC) treated cells, were plated at 2e5 cells per well in a 24-well dish. The next day, CAR T cells expressing the DLL3 targeted CAR were combined with the target cells at an E:T ratio of between 2: 1 to 4: 1, in this experiment an E:T ratio of 2: 1 was used. The effector CAR T cells and target cells were cocultured for three-day intervals. At each time point CAR T cells were counted using Acridine Orange / Propidium Iodide (AO / PI) and then at the same E:T ratio, CAR T cells were reseeded onto a new set of target cells, in this experiment a 2: 1 ratio of E:T cells was used, with 4e5 CAR T effector cells reseeded onto 2e5 HelaHl-huDLL3 mitomycin C (MMC) treated target cells. This process is repeated until CAR T cells do not proliferate anymore; the current experiment was still ongoing. The HelaHl-huDLL3 cells used in this experiment were mitomycin C (MMC) treated ahead of time. MMC is known to act as a potent bioreductive alkylating agent, primarily cross-linking DNA by forming interstrand covalent bonds at guanine-cytosine pairs to inhibit synthesis and cell division, thereby causing severe damage during the G1 and S phases and forcing cells to undergo cell cycle arrest.
[0353] Fold change amplification and the estimated total number of CAR T cells were quantified and graphed for each recorded time point in the experiment (FIG. 11A-1 IB). These results showed that PBMCs transduced with either the DLL3-LB or DLL3-T CARLeydig 775202were able to activate upon antigen recognition and go through expansion with persistence for at least 25 days.
[0354] These results suggest that lentiviral vectors packaged with solid tumor targeting CAR constructs can effectively transduce human lymphocytes and could be used to generate CAR T cells for treating solid tumors in vivo.EXAMPLE 2
[0355] This example demonstrates that lentiviral particles (LVPs) pseudotyped with 1:3 ratio of a recombinant protein of anti-CD3 scFv UCHT1 fused N terminal to VSIV-G with a deletion at residue K47 (UCHTl-VSIV-G-dK47) to VSIV-G- containing a BCMA-CAR transgene were able to successfully transduce T cells in vivo and generated CAR-T cells capable of reducing tumor burden.
[0356] To test the efficacy of LVPs pseudotyped with 1:3 ratio of a UCHT1-VSIV-G-dK47 to VSIV-G-dK47 containing a BCMA-CAR transgene to generate CAR-T cells in vivo, NSG MHC I / II DKO mice from Jackson Labs were intravenously implanted with OPM-2 cells (human multiple myeloma) expressing firefly luciferase (Flue). NSG MHC I / II DKO mice combine the features of the severe combined immune deficiency mutation (scid), IL2 receptor gamma chain deficiency, MHC class I molecule deficiency (H2-K and D), MHC class II molecule deficiency (IA), and exhibit a significant delay in the onset of graft versus host disease (GVHD).
[0357] Four groups of mice were prepared receiving either a saline injection (Group 1) or an injection of LVPs pseudotyped with VSIV-G-WT and containing a BCMA3-CAR transgene (Group 2), LVPs pseudotyped with a 1:3 ratio of UCHTl-VSIV-G-dK47 to VSIV-G-dK47 and containing a BCMA3 -CAR transgene (Group 3), or LVPs pseudotyped with a 1:3 ratio of UCHTl-VSIV-G-dK47 to VSIV-G-dK47 and containing a BCMA1-CAR transgene (Group 4) as shown in FIG. 12A and FIG. 12D.
[0358] NSG MHC I / II DKO mice were implanted with a tumor by IV injection of 1E6 OPM-2 cells expressing (Flue) in the tail vein. Mice were humanized by injection of 1E7 human PBMCs via IP injection on day 13 post tumor implantation. 8 days after PBMC injection mice were infected with LVPs as shown in Table 5. Mice underwent clinical observation for any moribund signs, weekly IVIS imaging, body weight was monitored, blood was collected in EDTA tubes for flow cytometry, tissue was collected at day 15 and day 29 from corresponding groups.Leydig 775202Table 5TiterLentivirus VP / ml TU / ml VP / mouse TU / mouse 1 Saline2 LV-BCMA3-CAR: Pseudo-G-WT 3.32E+10 5.43E+07 6E4-Q8 1E+06 3 L V-B CMA3 -UCHT 1 -GdK47 4.4E+10 5.19E+06 8E-i-()9 1E+06 4 LV-BCMAl-UCHTl-GdK47 1.96E+10 6.95E+06 3E+09 1E+06 5 LV-BCMAl-UCHTl-GdK47 1.96E+10 6.95E+06 1EA)9 5E+05 6 LV-BCMAl-UCHTl-GdK47 :PD 2.37E+09 2.81E+06 4E-W8 5E+05 7 LV-BCMAl-UCHTl-GdK47 : PD 2.37E+09 2.81E+06 1EA)8 1.5E+05 8 LV-BCMAl-UCHTl-GdK47 :PD 2.37E+09 2.81E+06 4E+07 5E+04
[0359] A random mouse BLI assay showed that the injection was 95% accurate (FIG. 12B), using a protocol adapted from Lin et al. (“IFN-y-dependent NK cell activation is essential to metastasis suppression by engineered Salmonella,” NATURE COMMUNICATIONS, 12: 2537 (2021)).
[0360] Samples of blood, bone marrow, and spleen underwent flow cytometry analysis as shown in FIG. 12C using combinations of the cell markers shown in Table 6. The flow cytometry was quantified as flow cytometry dot plots for samples taken 15 days after LVP treatment showing intensity of forward scatter height (FSC-H) vs. side scatter height (SSC-H), FSC-H vs. forward scatter area (FSC-A), and FSC-H vs. LD780, a dye for cell viability (FIG. 13A), mouse CD45 (mCD45) vs. human CD45 (hCD45), mCD45 vs. human CD3 (hCD3), and human CD8 (hCD8) vs. human CD4 (hCD4) (FIG. 13B). Further flow cytometry analysis is shown of flow cytometry dot plots showing intensity of GFP vs. CD3 in blood (FIG. 13C), bone marrow (FIG. 13D), and spleen (FIG. 13E) cells. These results demonstrate successful in vivo generation of CAR T cells in blood, bone marrow and spleen (GFP+ CD3+) by LVPs pseudotyped with a 1:3 ratio of UCHTl-VSIV-G-dK47 to VSIV-G-dK47 and containing a BCMA-CAR transgene, but not by LVPs pseudotyped with VSIV-G-WT. Additional flow cytometry analysis was performed showing intensity of GFP vs. CD3 in blood (FIG. 14A), bone marrow (FIG. 14B), and spleen (FIG. 14C) cells of OPM2-Fluc injected mice 29 days after LVP injection. These results showed a detectable but reduced presence of CAR T cells after 29 days. Further flow cytometry analysis was showing intensity of GFP vs. TIM3, an exhaustion marker, GFP vs. CD39, and GFP vs. PD1 in humanLeydig 775202CD4+ cells, human TCR5 / y+ cells, and human CD8+ cells from the spleen of 0PM2-Fluc injected mice 15 days after injection with saline (FIG. 15A), LVPs pseudotyped with VSIV-G-WT containing BCMA3-CAR (FIG. 15B), or LVPs pseudotyped with a 1:3 ratio of UCHTl-VSIV-G-dK47 to VSIV-G-dK47 containing BCMA3- CAR (FIG. 15C) or BCMA1-CAR (FIG. 15D). This data was quantified in a bar graph showing the percentage of GFP+ / CD8+ and GFP+ / CD4+ cells of 0PM2-Fluc injected mice 15 days after injection with saline or LVPs pseudotyped with VSIV-G-WT containing BCMA3-CAR or LVPs pseudotyped with a 1:3 ratio of UCHTl-VSIV-G-dK47 to VSIV-G-dK47 containing BCMA1-CAR or BCMA3-CAR (FIG. 15E). These results showed CD8+ T cell express higher GFP+CAR T cells than CD4+ T cells, but both CD4+ and CD8+ CAR T cell express high Tim3, an activation / exhaustion market for T cells.Table 5.

[0361] IVIS imaging was performed on NSG-MHC I / II DKO mice 1 day before (-1) being injected with OPM2-Fluc and 7, 14, 21, 28, 35, 42, and 49 after OPM2-Fluc injection and injected with saline (Group 1), 1E6 TU LVP pseudotyped with VSIV-G-WT containing BCMA3-CAR (Group 2), 1E6 TU LVP pseudotyped with a 1:3 ratio of UCHT1-VSIV-G-dK47 to VSIV-G-dK47 containing BCMA3-CAR (Group 3), 1E6 TU (Group 4) or 5E5 TU (Group 5) LVP pseudotyped with a 1:3 ratio of UCHTl-VSIV-G-dK47 to VSIV-G-dK47 containing BCMA1-CAR, or 5E5 TU (Group 6), 1.5E5 TU (Group 7), or 1E4 TU (Group 8) LVP pseudotyped with a 1:3 ratio of PD-UCHTl-VSIV-G-dK47 to VSIV-G-dK47 containing BCMA1-CAR (FIGS. 16A-16C). These results showed that while Group 2 mice and mouse #70 from Group 8 did have PBMCs they did not generate CAR-T cells, while the mice from Groups 3, 4, 5, 6, 7, and 8 (except mouse #70) did generate CAR-T cells and reduced or eliminated tumors.
[0362] The number of hCD45+ (FIG. 17A) and CD3+GFP+ (FIG. 17B) cells per pL of blood at 15, 22, 29, and 36 days post treatment with saline (Group 1), 1E6 TU LVP pseudotyped with VSIV-G-WT containing BCMA3-CAR (Group 2), 1E6 TU LVP pseudotyped with a 1:3 ratio of UCHTl-VSIV-G-dK47 to VSIV-G-dK47 containing BCMA3-CAR (Group 3), 1E6 TU (Group 4) or 5E5 TU (Group 5) LVP pseudotyped with a 1:3 ratio of UCHTl-VSIV-G-dK47 to VSIV-G-dK47 containing BCMA1-CAR, or 5E5 TU (Group 6), 1.5E5 TU (Group 7), or 5E4 TU (Group 8) LVP pseudotyped with a ratio of PD-UCHTl-VSIV-G-dK47 to VSIV-G-dK47 containing BCMAl-CARwas also quantified (FIGS. 17A-17B).
[0363] These results showed that based on the generation of BCMA CAR T cells and BLI assay result the most effective minimum dose for this study was 5E5 for the group 6 BCMA1 where all the mice survived 5E5 TU / mouse. These results also showed that BCMA CAR T cell number significantly increase with high tumor burden and decreased when mice were free from tumor cells. This suggests that BCMA CAR T cells remained longer in the blood in the low doses of LVP treated group to ensure the clearance of tumor from mice. These results also showed that blood CAR T cells start depleting earlier than spleen and bone marrow after elimination of OPM-2 cells.EXAMPLE 3
[0364] This example demonstrates that LVPs pseudotyped with 1:3 ratio of a UCHT1-VSIV-G-dK47 to VSIV-G-dK47 containing a BCMA-CAR transgene can successfullyLeydig 775202transduce T cells in vivo and generate CAR-T cells capable of reducing tumor burden even in a relapse model.
[0365] BCMA CAR T-cell therapy has demonstrated impressive overall response rates, ranging from 73% to 100% in clinical trials. Despite these encouraging results, a subset of patients experience relapse or disease progression, with some studies suggesting that up to 30-60% of patients could relapse. To further investigate the early immunological changes leading to persistent antitumor activity, mice were rechallenged with OPM-2 tumor, which mimics a relapse tumor.
[0366] OPM-2 Flue injected NSG MHC I / II DKO mice were prepared as in Example 2. Five groups of mice were prepared receiving either a saline injection (Group 1) or an injection of LVPs pseudotyped a 1:3 ratio of UCHTl-VSIV-G-dK47 to VSIV-G-dK47 and containing a BCMA33 -CAR transgene (Group 2), BCMA03-CAR transgene (Group 3), BCMA 1 -CAR transgene (Group 4), or BCMA2-CAR transgene (Group 5) as shown in FIG.18A.
[0367] IVIS imaging of NSG-MHC I / II DKO mice injected with OPM2-Fluc before being rechallenged at 56 days after LVP injection, 2 hours after being rechallenged at 68 days after LVP injection, and 21 days after being rechallenged at day 89 after injection with the LVPs containing BCMA33, BCMA003, BCMA1, or BCMA2 constructs was performed (FIG. 18B). These results showed the clearance of tumor cells upon rechallenge by Day 21 post rechallenge in groups 2-5, which suggests a robust memory response by CAR T cells.
[0368] A human IFN y ELISPOT assay was performed on the splenocytes of mice after the end of the rechallenging study and showed rechallenged CAR T cells are functional and can produce cytotoxic cytokines such as IFN y (FIGS. 18C-18E).
[0369] These results show that BCMA CAR LVP treated mice effectively eliminate rechallenged OPM-2 tumor, which mimics as relapse tumor, and keeps mice tumor free until the end of the experiment, 42 days after OPM-2 rechallenge and a total 110 days after LVP treatments. This results also show that most BCMA-CAR LVP mice retain IFN y producing memory cells 42 days after OPM-2 rechallenge as measured by IFN y ELISPOT assay.
[0370] To further study the efficacy of the BCMA containing LVPs at generating CAR-T cells in vivo and reducing tumor burden additional experiments were performed as shown in FIG. 19A.
[0371] OPM-2 Flue injected NSG MHC I / II DKO mice were prepared as in Example 2. Four groups of mice were prepared receiving either a saline injection (Group 1) or an injection of LVPs pseudotyped a 1:3 ratio of UCHTl-VSIV-G-dK47 to VSIV-G-dK47 andLeydig 775202containing a BCMA33 -CAR transgene that were not rechallenged with OPM-2 (Group 4), or were rechallenged with 1E6 OPM-2 tumor cells at day 56 (Groups 5 and 6) as shown in FIG.19A. 3 days after rechallenge, one mouse from group 1, 2 mice from group 4, and three mice from group 6 were sacrificed and blood, bone marrow, and spleen samples were collected. 7 days after rechallenge, one mouse from group 1, 2 mice from group 4, and three mice from group 6 were sacrificed and blood, bone marrow, and spleen samples were collected.
[0372] IVIS imaging was performed on NSG-MHC I / II DKO mice injected with OPM2-Fluc before being rechallenged, 2 hours after being rechallenged at 56 days after LVP injection, and 7 days after being rechallenged at day 63 after LVP injection with the LVPs containing BCMA1 CAR constructs (FIG. 19B). The clearance of tumor cells upon rechallenge by Day 7 post rechallenge indicates a robust memory response by CAR T cells.
[0373] Samples of blood, bone marrow, and spleen underwent flow cytometry analysis as shown in FIG. 20C using combinations of the cell markers shown in Table 6 and Table 7.Table 7.

[0374] The flow cytometry was quantified as flow cytometry dot plots showing intensity of GFP vs. CD3 in blood (FIG. 20A), bone marrow (FIG. 20B), and spleen (FIG. 20C) cells from OPM2-Fluc injected mice 59 days after injection with saline or LVP containing BCMA1-CAR and cells from OPM2-Fluc injected mice 3 days after rechallenge with OPM2Leydig 775202and 59 days after injection with LVP containing BCMA1-CAR. These results showed a reduction of rechallenged CAR-T cells as measured as GFP+ and CD3+ cells by day 3 after rechallenge. The same flow cytometry analysis of GFP vs. CD3 was performed in blood (FIG. 21A), bone marrow (FIG. 21B), and spleen (FIG. 21C) cells from 0PM2-Fluc injected mice 63 days after injection with saline or LVP containing BCMA1-CAR and cells from 0PM2-Fluc injected mice 7 days after rechallenge with 0PM2 and 63 days after injection with LVP containing BCMA22-CAR. These results also showed a reduction of rechallenged CAR-T cells by day 7 after rechallenge.
[0375] Further flow cytometry analysis was performed showing intensity of CD3 vs. CD39 in bone marrow cells from OPM2-Fluc injected mice that are injected with saline or LVP containing BCMA1-CAR at 15 days post LVP injection (FIG. 22A) and at 59 and 63 days post LVP injection (FIG. 22B) for mice that were not rechallenged or rechallenged with 0PM2 at day 56 post LVP injection. These results showed rechallenged CAR-T cells expressed exhaustion related marked CD39. Previous studies have shown that CD39 plays an important role in balancing immune activation and suppression in cancer immunology, that CD39 is expressed on T regulatory cells (Treg), which can suppress the activity of other immune cells, and that CD39 is involved in attenuating inflammatory responses through the conversion of ATP to adenosine (Xu et al., “CD39 transforming cancer therapy by modulating tumor microenvironment,” Cancer Letters , 597: 217072 (2024)).
[0376] Additional flow cytometry analysis was performed showing intensity of CD3 vs. PD1 in bone marrow cells from OPM2-Fluc injected mice that are injected with saline or LVP containing BCMA1-CAR at 15 days post LVP injection (FIG. 22C) and at 59 and 63 days post LVP injection (FIG. 22D) for mice that were not rechallenged or rechallenged with OPM2 at day 56 post LVP injection. These results showed rechallenged CAR-T cells expressed exhaustion related marked PD-1. Programmed cell death protein 1 (PD-1) is a known immune checkpoint molecule that plays a role in regulating immune responses.
[0377] In summary these results demonstrate that in vivo generated BCMA CAR T cell successfully cleared BCMA+ OPM-2 tumor. These results also show CAR-T cell generation was detected at 15 days post LVP treatment. BCMA CAR T cells increased in the presence of OPM-2 tumor but declined in the absence of tumor and successfully generated memory CAR T cells. These memory CART cells eliminated rechallenged OPM-2 tumor suggesting BCMA CAR T cells maintain antitumor function with IFNy producing memory cell pool to protect future relapse of same tumor. Additionally, these data showed minimal or almost no treatment associated toxicities in this OPM-2 -NSG-DKO mouse tumor model.Leydig 775202EXAMPLE 4
[0378] This example demonstrates the ability of lenti viruses to successfully target and transduce immunological cells in vivo.
[0379] To determine the biodistribution of lentiviruses pseudotyped with recombinant LDLR blinded VSV-G retargeted to CD3 Ail4 mice were intravenously administered the treatments as shown in Table 8 and FIG. 23.Table 8Group Treatment Dose (LVP) Number of animals 1 Mouse CD3 retargeted LV-Gqqq-CRE 1.5 x 10932 Human CD3 retargeted LV-Gqqq-CRE 1.5 x 10933 Human CD3 retargeted LV-GA47-CRE 1.5 x 10934 Untargeted LV-GA47-CRE 1.5 x 10935 Untargeted LV-Gqqq-CRE 1.5 x 10936 Saline - 37 LV-Gwt-CRE 1.5 x 1093
[0380] Ail 4 is a Cre reporter mouse strain designed to have a / ox -flanked STOP cassette preventing transcription of a CAG promoter-driven red fluorescent protein variant (tdTomato), which is all inserted into the Gt(ROSA)26Sor locus. The Ail4 mice were congenic on the C57BL / 6J genetic background and expressed robust tdTomato fluorescence following Cre-mediated recombination. tdTomato expression was assessed both directly via flow cytometry and indirectly via RFP immunostaining of tissue sections.
[0381] Groups of three Ail4 mice were intravenously administered saline as a negative control (group 6), lentivirus with a CRE transgene (SEQ ID NO: 11) and an expression plasmid expressing a glycoprotein expression plasmid encoding either VSV-G-WT (group 7), a recombinant LDLR blinded VSV-G with K47Q, R354Q, and Y209Q substitutions (G-QQQ) (group 5), a recombinant LDLR blinded VSV-G with a deletion at K47 (G-AK47) (group 4), a recombinant VSV-G-QQQ fused to a mouse anti-CD3 scFv (group 1), a recombinant VSV-G-QQQ fused to a human anti-CD3 scFv (group 2), or a recombinant VSV-G- AK47 fused to a human anti-CD3 scFv (group 3) at a dose of 1.5 x 109LVPs. 7 days after intravenous injection in the tail tissue was collected for immunohistochemistry analysis and flow cytometry analysis. Changes in body weight were monitored to determine if thereLeydig 775202was any evidence of systemic toxicity that could be attributed to the administration of lentivirus (FIG. 24A). No severe weight loss was observed in any of the experimental groups, and no significant difference was observed between treatment groups, indicating that none of the tested lentiviruses caused adverse effects on the general health of the animals.
[0382] Further, serum biochemistry and complete blood count (CBC) were carried out on day 7 following the administration of lentiviruses to determine any possible hematological and biochemical changes. CBC was performed on collected blood using a VETSCAN HM5™ hematology analyzer (FIGS. 24B-24C). These results showed white blood cell (WBC) count, lymphocyte count, monocyte count, neutrophil count, platelet count, and RBC count. Blood biochemistry profdes were measured from blood collected on day 7, and levels of the liver enzymes ALT, AST, and ALP were quantified (FIG. 24D). The area between the dashed lines represents the normal range for female 8-10-week-old C57BL6 mice (based on Charles River C57B1 / 6 mouse hematology report, 2012).
[0383] No appreciable changes were observed in the parameters analyzed and no variation was seen between the treatment groups (FIGS. 24B-24D). These results showed that the intravenous administration of lentivirus did not result in measurable systemic toxicity or hematological toxicity within day 7 post treatment.
[0384] The biodistribution of the Cre recombinase-expressing lentiviral vector delivered through the intravenous route was monitored by immunohistochemistry analysis of tdTomato expression in different tissues on day 7 post-infection to determine viral transduction range and selectivity (FIGS. 25A-25F).
[0385] tdTomato immunostaining of spleen tissues from mice treated with mouse CD3-retargeted LV-Gqqq-CRE (group 1) showed tdTomato-positive staining in both the perifollicular and follicular regions of spleen samples, while in mice treated with LV-Gwt-CRE (group 7) tdTomato-positive staining was predominantly confined to the perifollicular region (FIGS. 26A-26B).
[0386] tdTomato immunostaining of liver from mice treated with mouse CD3 -retargeted LV-Gqqq-CRE (group 1) showed mild to moderate levels of transduction with approximately 1-5% cells staining positive (FIG. 27). Group 1 mice showed tdTomato staining in a few hepatocytes (parenchymal liver cells) and morphologically macrophage-like cells and a similar staining pattern was seen in mice treated with LV-Gwt-CRE (group 7).
[0387] Bone marrow treated with mouse CD3 -retargeted LV-Gqqq-CRE (group 1) showed very low transduction levels, less than 1% of cells staining positive, with tdTomato expression observed mainly in dendritic-like cells, macrophages, and endothelial-like cellsLeydig 775202(FIG. 27). Similar staining paterns were observed in in mice treated with LV-Gwt-CRE (group 7). There was no observed variation in the level of transduction across the different groups, which suggested that there was no preferential transduction in this compartment.
[0388] No tdTomato positive cells were observed in the ovaries (FIG. 31), uterus, lungs (FIG. 30), kidney (FIG. 32), heart (FIG. 29), or tail injection site (FIG. 33) of the mice treated with mouse CD3-retargeted LV-Gqqq-CRE (group 1) suggesting that these organs or locations were refractory to lentivirus mediated transduction under the given conditions. Similar staining paterns were observed in in mice treated with LV-Gwt-CRE (group 7).
[0389] To determine the specificity of mouse CD3 -retargeted LV-Gqqq-CRE (group 1) to CD3+ T cells, tissues from these mice were analyzed and the retargeted lentivirus displayed a high level of lymphoid like cell transduction in lymph nodes, including the paracortex as seen in mouse 3 of group 1, and maintained a similar background transduction in other organs (FIGS. 34A-34C). None of the human CD3-targeted LV (group 2) or controls (groups 6 and 7) had a similar transduction profile thus establishing the specificity of mouse CD3 -retargeted LV-Gqqq-CRE to murine T cells (FIGS. 34B-34D). Notably, the mice treated with LV-Gwt-CRE (group 7) had a higher transduction frequency in the non-CD3+ T cell populations in lymph nodes (data not shown), which suggests that its specificity may not be limited to conventional T cell populations.
[0390] To verify that the transduced lymphoid-like cells are T cells, an immunofluorescence assay was performed to detect B cells (CD20+) and T cells (CD3+) alongside tdTomato staining (FIGS. 35A-35C). FIGS. 35A-35C showed the results from immunofluorescence staining that was performed using Opal multiplex staining that were captured using a Vectra Polaris system at 20 x magnification. These results demonstrate colocalization of tdTomato staining with CD3+T cells (highlighted in circles), but not with B cells, in the mice treated with mouse CD3 -retargeted LV-Gqqq-CRE (group 1). In contrast, mice treated with wild-type lentiviruses (group 7) exhibited minimal tdTomato colocalization, indicating a lack of specific targeting. These findings suggest that the mouse CD3 -retargeted LV-Gqqq-CRE virus preferentially targeted T cells rather than B cells within the lymph node paracortex microenvironment. Further, these results suggest that CD3-targeted T cell transduction probably occurs within the high endothelial vessels (HEV) of the LN paracortex.
[0391] The tdTomato positive staining across treatment groups in the different tissue was quantified and the findings are shown in Table 9. In Table 9 “ND” indicates no tdTomato positive staining was detected; “+++” indicates a high level of tdTomato positive staining,Leydig 775202indicating that 5-15% of the cells in the representative image showed positive tdTomato staining; “++” denotes a moderate level of positivity, with 1-5% of the observed cellsshowing positive tdTomato staining; and “+” indicates a minimal level of positivity, where less than 1% of the cells display positive staining. All images were subjectively quantified on a representative image under 20X magnification.Table 9.

[0392] To quantify the RFP+ cells in lymph node treated with Saline, LV-Gwt-CRE, Mouse CD3 targeted LV-Gqqq-CRE, Human CD3 targeted LV-Gqqq-CRE, Human CD3 targeted LV-GA47-CRE, LV-GA47-CRE, and LV-Gqqq-CRE a two-way ANOVA was performed (FIG. 36). Data were presented as mean ± SEM, and statistical significance was indicated by p < 0.05 (*), p < 0.01 (**), p < 0.0001 (****).
[0393] The results of tdTomato RFP-based immunostaining showed that among all the tissues analyzed, the liver, spleen, and bone marrow had minimal background transduction inLeydig 775202all the experimental groups with other tissues showing no expression. This finding was consistent across all groups, irrespective of whether the mice received blinded, retargeted, or wild-type VS V-G pseudotyped lentiviruses. These results suggest that systemically delivered lentiviruses cause little integration and do not lead to widespread, non-specific integration in these important hematopoietic and metabolic organs.
[0394] Furthermore, these results suggest that the CD3 retargeted lentiviruses could be used to selectively transduce immunological cells, such as lymphocytes and macrophages, with CAR transgenes and other payloads in vivo, to generate CAR T cells for treatment of solid tumors.EXAMPLE 5
[0395] This example demonstrates that lentiviruses pseudotyped with VSIV-G and retargeted to CD3 containing one or more CAR transgenes targeted to a solid tumor antigen and a B cell antigen, with or without a transgene for an exogenous cytokine, are able to successfully transduce T cells in vivo and generate CAR-T cells capable of reducing solid tumor burden.
[0396] Lentiviruses pseudotyped with either wild type VSIV-G and a capping protein comprising the CR1, CR2, and CR3 domains of LDLR fused to an oligomerization domain derived from the GCN4 leucine / isoleucine zipper peptide, helical peptide VL by a (G4S)3 linker fused to the anti-CD3 scFv UCHT1 or a 1:3 ratio of a recombinant LDLR blinded VSIV-G fused to the anti-CD3 scFv UCHT1 : LDLR blinded VSIV-G were packaged with one or more transgenes for a CAR targeted to a solid tumor antigen and a B cell and one or more transgenes for an exogenous cytokine. Tandem CAR constructs are prepared with a DLL3 solid tumor antigen binding domain and a BCMA B cell antigen binding domain or a B7H3 solid tumor antigen binding domain and a BCMA B cell antigen binding domain. Dual CAR constructs with one CAR containing a DLL3 solid tumor antigen binding domain or a B7H3 solid tumor antigen binding domain and the other CAR containing a BCMA B cell antigen binding domain are prepared. Constructs are prepared encoding IL-18, IL-36, or both IL-18 and IL-36. Lentiviruses are prepared as shown in Table 10 below.Leydig 775202Table 10Lentivirus Retargeting TransgenesUCHT1-LDLR Blinded VSV-G: DLL3+BCMA Tandem CARLDLR Blinded VSV-G (1:3)UCHT1-LDLR Blinded VSV-G: DLL3+BCMA Tandem CAR and IL- 18 LDLR Blinded VSV-G (1:3)UCHT1-LDLR Blinded VSV-G: DLL3+BCMA Tandem CAR and IL-36 LDLR Blinded VSV-G (1:3)UCHT1-LDLR Blinded VSV-G: DLL3+BCMA Tandem CAR and IL-18+IL-36 LDLR Blinded VSV-G (1:3)UCHT1-LDLR Blinded VSV-G: DLL3+BCMA Dual CARsLDLR Blinded VSV-G (1:3)UCHT1-LDLR Blinded VSV-G: DLL3+BCMA Dual CARs and IL- 18 LDLR Blinded VSV-G (1:3)UCHT1-LDLR Blinded VSV-G: DLL3+BCMA Dual CARs and IL-36 LDLR Blinded VSV-G (1:3)UCHT1-LDLR Blinded VSV-G: DLL3+BCMA Dual CARs and IL-18+IL-36 LDLR Blinded VSV-G (1:3)UCHT1-LDLR Blinded VSV-G: B7H3+BCMA Tandem CARLDLR Blinded VSV-G (1:3)UCHT1-LDLR Blinded VSV-G: B7H3+BCMA Tandem CAR and IL- 18 LDLR Blinded VSV-G (1:3)UCHT1-LDLR Blinded VSV-G: B7H3+BCMA Tandem CAR and IL-36 LDLR Blinded VSV-G (1:3)UCHT1-LDLR Blinded VSV-G: B7H3+BCMA Tandem CAR and IL-18+IL-36 LDLR Blinded VSV-G (1:3)UCHT1-LDLR Blinded VSV-G: B7H3+BCMA Dual CARsLDLR Blinded VSV-G (1:3)UCHT1-LDLR Blinded VSV-G: B7H3+BCMA Dual CARs and IL- 18 LDLR Blinded VSV-G (1:3)UCHT1-LDLR Blinded VSV-G: B7H3+BCMA Dual CARs and IL-36 LDLR Blinded VSV-G (1:3)UCHT1-LDLR Blinded VSV-G: B7H3+BCMA Dual CARs and IL-18+IL-36 LDLR Blinded VSV-G (1:3)UCHT1-VL CAP + VSIV-G WT DLL3+BCMA Tandem CARUCHT1-VL CAP + VSIV-G WT DLL3+BCMA Tandem CAR and IL- 18 UCHT1-VL CAP + VSIV-G WT DLL3+BCMA Tandem CAR and IL-36 UCHT1-VL CAP + VSIV-G WT DLL3+BCMA Tandem CAR and IL-18+IL-36 UCHT1-VL CAP + VSIV-G WT DLL3+BCMA Dual CARsUCHT1-VL CAP + VSIV-G WT DLL3+BCMA Dual CARs and IL- 18 UCHT1-VL CAP + VSIV-G WT DLL3+BCMA Dual CARs and IL-36 UCHT1-VL CAP + VSIV-G WT DLL3+BCMA Dual CARs and IL-18+IL-36 UCHT1-VL CAP + VSIV-G WT B7H3+BCMA Tandem CARUCHT1-VL CAP + VSIV-G WT B7H3+BCMA Tandem CAR and IL- 18 UCHT1-VL CAP + VSIV-G WT B7H3+BCMA Tandem CAR and IL-36 UCHT1-VL CAP + VSIV-G WT B7H3+BCMA Tandem CAR and IL-18+IL-36 UCHT1-VL CAP + VSIV-G WT B7H3+BCMA Dual CARsUCHT1-VL CAP + VSIV-G WT B7H3+BCMA Dual CARs and IL- 18 UCHT1-VL CAP + VSIV-G WT B7H3+BCMA Dual CARs and IL-36UCHT1-VL CAP + VSIV-G WT B7H3+BCMA Dual CARs and IL-18+IL-36
[0397] Solid tumor xenograft mice are prepared and administered either a saline injection as a control or an injection of one of the lentiviruses shown in Table 10. IVIS imaging of the injected mice is performed to assess tumor clearance. Samples of blood, bone marrow, andLeydig 775202spleen are collected from the injected mice and undergo flow cytometry analysis to assess transduction efficiency and T cell activation.EXAMPLE 6
[0398] This example demonstrates the development of transfer plasmid CAR constructs optimized for improved specificity, transgene expression, CAR potency, and increased safety profiles whether within the LTRs or the plasmid backbone.
[0399] In order to maximize transgene expression in transduced immune cells, while minimizing or eliminating expression in other cell types, specifically packaging cell lines, the promoters are optimized through rational design and incorporation of miRNA recognition elements (MREs) into the transfer plasmid. Additional approaches to optimize transgene constructs include optimizing other regulatory elements within the plasmid backbone for better packaging and transgene expression. Optimization for expression of two transgenes within one delivery vehicle, such as for a solid tumor targeting CAR and the solid tumor antigen is also performed. Optimization of the signaling domains of CAR constructs is also tested to improve CAR T potency.EXAMPLE 7
[0400] This example demonstrates treating a human identified as having a solid tumor with lentiviruses pseudotyped with VSIV-G and retargeted to CD3 containing one or more CAR transgenes targeted to a solid tumor antigen and a B cell antigen, with or without a transgene for an exogenous cytokine as described in Example 5.
[0401] A human identified as having a solid tumor of small cell lung cancer that expresses DLL3 or B7H3 antigen is administered one or more lentiviruses as described in Table 10 to generate CAR T cells expressing CARs specific for DLL3 or B7H3 and BCMA and cytokines in vivo. The lentivirus is specifically retargeted to infect T cells within the human and express DLL3 CAR or B7H3 CAR with BCMA CAR T cells and cytokines within the human.
[0402] To determine if the in vivo generated CAR T cells are stimulated upon recognition of BCMA antigen in the B cells by the BCMA CAR on the CAR T cells and if this results in increased CAR T proliferation, flow cytometry analysis is performed. Expression levels of the CAR T produced cytokines are also quantified. CAR T cell expansion and persistence is also assessed by flow cytometry analysis.Leydig 775202
[0403] The efficacy of the CAR T cells and the CAR T produced cytokines on reducing growth or clearing DLL3+ or B7H3 + tumor cells in the tumor microenvironment (TME) within the human is assessed. Analysis is performed to identify memory CAR T cells and persistence of the memory CAR T cells to assess the ability of the memory CAR T cells to reduce growth or clear tumor relapse.EXAMPLE 8
[0404] This example demonstrates the therapeutic efficacy of armored CAR T cells generated in vivo following administration of a retargeted retroviral vector in an immunocompetent mouse model. The vector is configured to target CD3 -expressing cells and comprises transgenes encoding dual CAR constructs specific for DLL3 and / or B7-H3 and a B cell antigen, such as BCMA or CD22, in combination with cytokines including IL-36y and IL-18. A corresponding vector lacking cytokine transgenes is used as a control.
[0405] In immunocompetent models, cytokines co-expressed with the CAR constructs may exert pleiotropic effects, including supporting CAR T cell survival, expansion, and persistence, as well as modulating other immune cell populations within the tumor microenvironment in a manner that promotes antitumor immunity.
[0406] C57BL / 6 mice engineered to express human CD3 and human BCMA are implanted subcutaneously with approximately 0.5 x 106to 1.0 x 106cells from a syngeneic tumor line, such as MC38 cells engineered to express human DLL3 and / or human B7-H3.
[0407] Following establishment of palpable tumors, the retargeted viral vector is administered to the mice. Tumor growth, body weight, and generation of CAR-expressing T cells are monitored overtime, including analysis of blood, bone marrow, spleen, and lymph nodes by flow cytometry. The ability of the retargeted vector to generate CAR T cells in vivo that express DLL3- and / or B7-H3-specific CARs together with a B cell antigen-targeting CAR, and cytokines such as IL- 18 and IL-36y is assessed by flow cytometry and immunohistochemistry.
[0408] The in vivo generated CAR T cells may traffic to the tumor and mediate cytotoxic activity against MC38 tumor cells expressing DLL3 and / or B7-H3. Reduction in tumor burden or tumor clearance is assessed by IVIS imaging.
[0409] Following tumor reduction or clearance, mice are rechallenged with parental MC38 tumor cells lacking expression of DLL3 and / or B7-H3. Tumor growth and immune cell phenotyping is monitored to assess the durability and breadth of the antitumor response.Leydig 775202The difference in reduced or absent tumor growth upon rechallenge in mice treated with vectors containing one or more cytokine transgene is compared to mice treated with vectors lacking cytokines. Reduced or absent tumor growth in mice treated with vectors containing one or more cytokine transgene may be indicative of sustained immune responses, including the generation of persistent CAR T cells and / or activation of endogenous T cell populations capable of recognizing tumor antigens beyond the CAR-targeted antigen, thereby addressing tumor antigen heterogeneity.
