DETAILED DESCRIPTION OF THE INVENTION

[0267] Terms used in the claims and specification are defined as set forth below unless otherwise specified.

[0268] The term in vivo refers to processes that occur in a living organism.

[0269] The term mammal as used herein includes both humans and non-humans and include but is not limited to humans, non-human primates, canines, felines, murines, bovines, equines, and porcines.

[0270] The term percent identity, in the context of two or more nucleic acid or polypeptide sequences, refer to two or more sequences or subsequences that have a specified percentage of nucleotides or amino acid residues that are the same, when compared and aligned for maximum correspondence, as measured using one of the sequence comparison algorithms described below (e.g., BLASTP and BLASTN or other algorithms available to persons of skill) or by visual inspection. Depending on the application, the percent identity can exist over a region of the sequence being compared, e.g., over a functional domain, or, alternatively, exist over the full length of the two sequences to be compared.

[0271] For sequence comparison, typically one sequence acts as a reference sequence to which test sequences are compared. When using a sequence comparison algorithm, test and reference sequences are input into a computer, subsequence coordinates are designated, if necessary, and sequence algorithm program parameters are designated. The sequence comparison algorithm then calculates the percent sequence identity for the test sequence(s) relative to the reference sequence, based on the designated program parameters.

[0272] Optimal alignment of sequences for comparison can be conducted, e.g., by the local homology algorithm of Smith & Waterman, Adv. Appl. Math. 2:482 (1981), by the homology alignment algorithm of Needleman & Wunsch, J. Mol. Biol. 48:443 (1970), by the search for similarity method of Pearson & Lipman, Proc. Nat'l. Acad. Sci. USA 85:2444 (1988), by computerized implementations of these algorithms (GAP, BESTFIT, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer Group, 575 Science Dr., Madison, Wis.), or by visual inspection (see generally Ausubel et al., infra).

[0273] One example of an algorithm that is suitable for determining percent sequence identity and sequence similarity is the BLAST algorithm, which is described in Altschul et al., J. Mol. Biol. 215:403-410 (1990). Software for performing BLAST analyses is publicly available through the National Center for Biotechnology Information (www.ncbi.nlm.nih.gov/).

[0274] The term sufficient amount means an amount sufficient to produce a desired effect, e.g., an amount sufficient to modulate protein aggregation in a cell.

[0275] The term therapeutically effective amount is an amount that is effective to ameliorate a symptom of a disease. A therapeutically effective amount can be a prophylactically effective amount as prophylaxis can be considered therapy.

[0276] It must be noted that, as used in the specification and the appended claims, the singular forms a, an and the include plural referents unless the context clearly dictates otherwise.

[0277] The term about is used herein to provide literal support for the exact term that it precedes, and allows for near approximations of the term. For example, certain ranges or similarity may be presented with numerical ranges preceded by the term about. If the degree of approximation is not otherwise clear from the context, about means either within plus or minus 10% of the provided value, or rounded to the nearest significant figure, in all cases inclusive of the provided value. In some embodiments, the term about indicates the designated valueup to 10%, up to +5%, or up to +1%.

Inducible Cell Death Systems

[0278] The ability to induce cell death using synthetic ligands, particularly those approved for clinical use, would be beneficial in therapeutic applications, such as in the field of cell and gene therapy. Cell and gene therapies show great clinical promise; however, they carry a risk of off-target toxicity that can result in organ damage and patient deaths. It can be desirable to engineer cell and gene therapy products with a safety switch, e.g., an inducible cell death system, to address potential toxicity concerns.

[0279] Synthetic ligands that bind to ER have been developed for treating ER-positive cancers such as ER-positive breast cancer. For example, active metabolites of the drug tamoxifen induce nuclear translocation of ER and antagonize ER in a tissue-selective manner.

[0280] Tamoxifen and its active metabolites are also utilized as a tool for controlling nuclear localization in the research setting. For example, an ER ligand binding domain variant known as ERT2 has been used as a fusion protein with Cre recombinase to regulate Cre recombinase-based gene editing in animal model systems.

[0281] As shown herein, ERT2 mutants engineered with additional amino acid substitutions can be implemented into inducible cell death systems to induce potent cell killing. Accordingly, provided herein are inducible cell death systems that include modified estrogen receptor ligand binding domains (ER-LBD). The inducible cell death systems described herein can include a polypeptide, wherein the polypeptide includes a ligand binding domain and a cell death inducing domain. In some embodiments, a polypeptide herein is configured, upon contact with a ligand of the ligand binding domain, to regulate a cell-death inducing pathway in a cell in which the polypeptide is expressed. In some embodiments, a polypeptide herein is configured, upon contact with a ligand of the ligand binding domain, to generate a cell-death inducing signal in a cell in which the polypeptide is expressed.

[0282] FIG. 19 shows exemplary inducible cell-death systems, including ER-mediated transcriptional induction via nuclear localization (top panel) and ER-mediated suicide-switch killing via dimerization (bottom panel).

[0283] In some embodiments, a polypeptide herein is configured, upon contact with a ligand of the ligand binding domain, to regulate expression of polynucleotides and/or further polypeptides of a cell-death inducing pathway in a cell in which the polypeptide is expressed. In exemplary embodiments of a polypeptide comprising a modified ER-LBD as disclosed herein and a cell death inducing domain, the cell death-inducing domain is a transcription factor comprising a nucleic acid-binding domain disclosed herein (e.g., ZF10-1 DNA binding domain as depicted in FIG. 19, top panel) and a transcriptional effector domain, also referred to herein as a transcription modulator (e.g., p65 as depicted in FIG. 19, top panel). Without wishing to be bound by theory, upon contact of the ligand with the ligand binding domain (e.g., wherein the contacting comprises binding of the ligand to the ligand binding domain), the polypeptide may translocate to the nucleus to activate expression of a death inducing payload.

[0284] The inducible cell death system includes systems where a polypeptide is or comprises a first polypeptide monomer and the inducible cell-death system further includes a second polypeptide monomer. Polypeptide monomers refer to proteins, protein subunits, and/or protein domains that are configured to, upon contact with a ligand of the ER-LBD (e.g., wherein the contacting comprises binding of the ligand to the ligand binding domains of the first and the second polypeptide monomers), generate a cell-death inducing signal in a cell in which the first and the second polypeptide monomers are expressed. In some embodiments, the first polypeptide monomer and the second polypeptide monomer are configured to oligomerize with each other upon contact with a ligand of the ligand binding domain (e.g., wherein the contacting comprises binding of the ligand to the ligand binding domains of the first and the second polypeptide monomers), thereby generating the cell-death inducing signal in a cell in which the first polypeptide monomer and the second polypeptide monomer are expressed. Without wishing to be bound by theory, binding of the ligand binding domains of the first and the second polypeptide monomers with the ligand may induce oligomerization of the polypeptide monomers, wherein the oligomerization generates the cell-death inducing signal by activating the cell death inducing domain. See, e.g., FIG. 19 (bottom panel, depicting caspase 9 as an exemplary cell death inducing domain).

[0285] Such inducible cell death systems can beneficially improve the safety profile of cell and gene therapy products.

[0286] Exemplary cell death-inducing domains and/or death-inducing payloads can be derived from a protein such as one or more of: a caspase (e.g., any one of caspase 1-11, such as caspase 3, caspase 6, caspase 7, caspase 8, caspase 9), Diphtheria toxin fragment A (DTA), Bax, Bak, Bok, Bad, Bcl-Xs, Bik, Bcl-2-interacting protein 3 (BNIP3), Fas, Fas-associated protein with death domain (FADD), tumor necrosis factor receptor type 1-associated death domain protein (TRADD), a TNF receptor (TNF-R), APAF-1, granzyme B, second mitochondria-derived activator of caspases (SMAC), Omi, Bmf, Bid, Bim, p53-upregulated modulator of apoptosis (PUMA), Noxa, Blk, Hrk, Cytochrome c, Arts, TNF-related apoptosis-inducing ligand (TRAIL), Herpes Simplex Virus thymidine kinase (HSV-TK), Varicella Zoster Virus thymidine kinase (VZV-TK), viral Spike protein, Carboxyl esterase, cytosine deaminase, nitroreductase Fksb, Carboxypeptidase G2, Carboxypeptidase A, Horseradish peroxidase, Linamarase, Hepatic cytochrome P450-2B1, and/or Purine nucleoside phosphorylase. Exemplary sequences can be found in Table A.

A modified XIAP can include an amino acid substitution at position 325 of SEQ ID NO: 107 that is P325S.

Chimeric Proteins

[0291] In some aspects, the present disclosure provides chimeric proteins including a polypeptide of interest fused to the modified ER-LBD. Polypeptides of interest can include a cell death inducing domain, wherein the chimeric protein is configured upon contact with a ligand of the ligand binding domain to generate a cell-death inducing signal in a cell in which the polypeptide is expressed.

[0292] A polypeptide of interest can include a pro-apoptotic factor, such as a pro-apoptotic transcription factor. A polypeptide of interest can include a pro cell survival factor and/or an inhibitor of a pro cell survival factor. A polypeptide of interest can include polypeptide monomers that are generally inactive in monomeric form but active upon oligomerization.

[0293] The modified ER-LBD can be capable of inducing oligomerization and/or nuclear localization upon binding to a non-endogenous ligand. Thus, fusion of a modified ER-LBD to a polypeptide of interest may allow for control of cellular localization and/or oligomerization of the polypeptide of interest.

[0294] In some embodiments, the polypeptide of interest may be fused to the modified ER-LBD directly, or indirectly, e.g., via a linker. One or more linkers can be used between various domains of chimeric proteins, such as between an ER-LBD and a polypeptide of interest. For example, a polypeptide linker can include an amino acid sequence such as one or more of: GGGGSGGGGSGGGGSVDGF (SEQ ID NO: 4) and ASGGGGSAS (SEQ ID NO: 5).

[0295] In some embodiments, the polypeptide of interest includes at least one nucleic acid binding domain. In some embodiments, the nucleic acid binding domain is a zinc-finger domain. In some embodiments, the chimeric protein includes a transcription modulator, such as a transcription activator or a transcription repressor. Inclusion of a nucleic acid binding domain may allow for targeted nucleic acid binding by the chimeric protein that is inducible by a non-endogenous ligand (e.g., 4-OHT or endoxifen).

[0296] In some aspects, the nucleic acid binding domain comprises a DNA binding zinc finger protein domain (ZF protein domain). In some aspects, the ZF protein domain is modular in design and is composed of zinc finger arrays (ZFA). In some aspects, the transcriptional effector domain is selected from a Herpes Simplex Virus Protein 16 (VP16) activation domain; an activation domain comprising four tandem copies of VP16, a VP64 activation domain; a p65 activation domain of NFB; an Epstein-Barr virus R transactivator (Rta) activation domain; a tripartite activator comprising the VP64, the p65, and the Rta activation domains (VPR activation domain); a tripartite activator comprising the VP64, the p65, and the HSF1 activation domains (VPH activation domain); a histone acetyltransferase (HAT) core domain of the human E1A-associated protein p300 (p300 HAT core activation domain); a Krppel associated box (KRAB) repression domain; a Repressor Element Silencing Transcription Factor (REST) repression domain; a WRPW motif (SEQ ID NO:156) of the hairy-related basic helix-loop-helix repressor proteins, the motif is known as a WRPW (SEQ ID NO:156) repression domain; a DNA (cytosine-5)-methyltransferase 3B (DNMT3B) repression domain; and an HP1 alpha chromoshadow repression domain.

[0297] In some embodiments, the ZF protein domain is modular in design and is composed of zinc finger arrays (ZFA). A zinc finger array comprises multiple zinc finger protein motifs that are linked together. Each zinc finger motif binds to a different nucleic acid motif. This results in a ZFA with specificity to any desired nucleic acid sequence. The ZF motifs can be directly adjacent to each other, or separated by a flexible linker sequence. In some embodiments, a ZFA is an array, string, or chain of ZF motifs arranged in tandem. A ZFA can have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15 zinc finger motifs. The ZFA can have from 1-10, 1-15, 1-2, 1-3, 1-4, 1-5, 1-6, 1-7, 1-8, 1-9, 2-3, 2-4, 2-5, 2-6, 2-7, 2-8, 2-9, 2-10, 3-4, 3-5 3-6, 3-7, 3-8, 3-9, 3-10, 4-5, 4-6, 4-7, 4-8, 4-9, 4-10, 5-6, 5-7, 5-8, 5-9, 5-10, or 5-15 zinc finger motifs.

[0298] The ZF protein domain can have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, or more ZFAs. The ZF domain can have from 1-10, 1-15, 1-2, 1-3, 1-4, 1-5, 1-6, 1-7, 1-8, 1-9, 2-3, 2-4, 2-5, 2-6, 2-7, 2-8, 2-9, 2-10, 3-4, 3-5 3-6, 3-7, 3-8, 3-9, 3-10, 4-5, 4-6, 4-7, 4-8, 4-9, 4-10, 5-6, 5-7, 5-8, 5-9, 5-10, or 5-15 ZFAs. In some embodiments, the ZF protein domain comprises one to ten ZFA(s). In some embodiments, the ZF protein domain comprises at least one ZFA. In some embodiments, the ZF protein domain comprises at least two ZFAs. In some embodiments, the ZF protein domain comprises at least three ZFAs. In some embodiments, the ZF protein domain comprises at least four ZFAs. In some embodiments, the ZF protein domain comprises at least five ZFAs. In some embodiments, the ZF protein domain comprises at least ten ZFAs.

Modified Estrogen Receptor Ligand Binding Domains (ER-LBD)

[0303] The present disclosure provides a modified estrogen receptor ligand binding domain (ER-LBD) comprising an amino acid sequence corresponding to a hormone binding domain of a reference human estrogen receptor sequence, SEQ ID NO: 1 (human Estrogen Receptor, UniProt ID No: P03372), comprising amino acid substitutions G400V, M543A, and L544A or amino acid substitutions G400V, M543A, L544A, and V595A, and comprising one or more additional amino acid substitutions to ligand binding residues selected from: positions 343-354, positions 380-392, positions 404-463, and positions 517-540, and position 547. It is to be understood that such amino acid substitutions are with reference to SEQ ID NO: 1. In some aspects, the one or more amino acid substitutions result in: (a) greater sensitivity to a non-endogenous ligand as compared to an endogenous ligand, (b) greater sensitivity to a non-endogenous ligand as compared to an ER-LBD of SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 3A, or SEQ ID NO: 3B, and/or (c) greater selectivity to a non-endogenous ligand as compared to an ER-LBD of SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 3A, or SEQ ID NO: 3B.

[0304] In some embodiments, the one or more additional amino acid substitutions results in greater sensitivity to a non-endogenous ligand as compared to an ER-LBD of SEQ ID NO: 2. In some embodiments, the one or more additional amino acid substitutions results in greater sensitivity to a non-endogenous ligand as compared to an ER-LBD of SEQ ID NO: 3. In some embodiments, the one or more additional amino acid substitutions results in greater sensitivity to a non-endogenous ligand as compared to an ER-LBD of SEQ ID NO: 3A. In some embodiments, the one or more additional amino acid substitutions results in greater sensitivity to a non-endogenous ligand as compared to an ER-LBD of SEQ ID NO: 3B. In some embodiments, the one or more additional amino acid substitutions results in greater selectivity to a non-endogenous ligand as compared to an ER-LBD of SEQ ID NO: 2. In some embodiments, the one or more additional amino acid substitutions results in greater selectivity to a non-endogenous ligand as compared to an ER-LBD of SEQ ID NO: 3. In some embodiments, the one or more additional amino acid substitutions results in greater selectivity to a non-endogenous ligand as compared to an ER-LBD of SEQ ID NO: 3A. In some embodiments, the one or more additional amino acid substitutions results in greater selectivity to a non-endogenous ligand as compared to an ER-LBD of SEQ ID NO: 3B.

[0305] In some embodiments, the modified ER-LBD may further comprise yet other modifications, e.g., amino acid substitutions, deletions, and/or insertions (with reference to SEQ ID NO: 1). Such yet other modifications can be within or outside of positions 343-354, positions 380-392, positions 404-463, positions 517-540, and/or position 547, with reference to SEQ ID NO: 1. Such yet other modifications can be within or outside of outside of positions 283-594, with reference to SEQ ID NO: 1.

[0306] Ligand binding residues refers to residues located at the ligand binding pocket of estrogen receptor (ER) or an ER-ligand binding domain, and includes the pocket for binding to an endogenous ligand (e.g., estradiol) and the pocket for binding to a non-endogenous ligand such as 4-OHT. In some embodiments, the hormone binding domain of a reference human estrogen receptor sequence corresponds to positions 282-595 of human estrogen receptor (SEQ ID NO: 1). It is to be understood that the hormone binding domain does not necessarily require all of amino acid residues 282-595 of SEQ ID NO: 1. By way of example only, it is to be understood that positions 283-594 of SEQ ID NO: 1, or other functional truncations or fragments thereof, may function as the hormone binding domain.

[0307] Residues within positions 343-354, positions 380-392 and positions 404-463 corresponding to SEQ ID NO: 1 are involved in binding to both endogenous and non-endogenous ligands. Residues within positions 517-547 (e.g., residues 517-40 and residue 547) corresponding to SEQ ID NO: 1 are located within a helix referred to as helix 12 and are involved in endogenous ligand binding.

[0308] Greater sensitivity to a non-endogenous ligand as compared to sensitivity to a non-endogenous ligand means that the modified ER-LBD binds to a non-endogenous ligand (e.g., endoxifen) with a higher affinity as compared to the affinity of its binding to an endogenous ligand (e.g., estradiol).

[0309] Greater sensitivity to a non-endogenous ligand as compared to sensitivity an ER-LBD not including the one or more amino acid substitutions (e.g., an ER-LBD comprising the amino acid sequence of SEQ ID NO: 2 or SEQ ID NO: 3) means that the modified ER-LBD binds to a non-endogenous ligand (e.g., endoxifen) with a higher affinity as compared to the affinity of binding of ER-LBD not including the one or more additional amino acid substitutions to the non-endogenous ligand. In some embodiments, the greater sensitivity is at least a 1.5-fold, at least a 2-fold, at least a 3-fold, at least a 4-fold, or at least a 5-fold improvement in binding affinity to a non-endogenous ligand, as compared to binding of an ER-LBD not including the one or more additional amino acid substitutions. In some embodiments, greater sensitivity is demonstrated by greater transcriptional modulation (e.g., greater transcriptional activation or greater transcriptional repression) of a chimeric transcription factor including a modified ER-LBD, as compared to a chimeric transcription factor including an ER-LBD that lacks the one or more additional amino acid substitutions. In some embodiments, in a transfection of transduction assay, a chimeric transcription factor including a modified ER-LBD is capable of inducing at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, or at least 35% greater expression of a reporter under control of a chimeric transcription factor-responsive promoter in response to a non-endogenous ligand (e.g., 4-OHT) (as measured by % of cells positive for the reporter, or as measured by geometric mean fluorescent intensity) as compared to the expression of the reporter under the same conditions but with an ER-LBD that lacks the one or more additional amino acid substitutions.

[0310] Greater selectivity to a non-endogenous ligand refers to preferential binding to a non-endogenous ligand (e.g., 4-OHT or endoxifen) as compared to an endogenous ligand (e.g., estradiol). Selectivity may be measured using a selectivity coefficient, which is the equilibrium constant for the reaction of displacement by one ligand (e.g., a non-endogenous ligand) of another ligand (e.g., an endogenous ligand) in a complex with the substrate (e.g., a modified ER-LBD). The greater the selectivity coefficient, the more a competing ligand (e.g., an endogenous ligand) will displace the initial ligand (e.g., a non-endogenous ligand) from the complex formed with the substrate (e.g., a modified ER-LBD). In some embodiments, greater selectivity is demonstrated by improved transcriptional modulation of a chimeric transcription factor in the presence of a non-endogenous ligand as compared to transcriptional modulation in the presence of an endogenous ligand. In some embodiments, in a transfection of transduction assay, a chimeric transcription factor including a modified ER-LBD is capable of inducing at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, or at least 35% greater expression of a reporter under control of a chimeric transcription factor-responsive promoter in response to a non-endogenous ligand (e.g., 4-OHT) (as measured by % of cells positive for the reporter, or as measured by geometric mean fluorescent intensity) as compared to the expression of the reporter under the same conditions but in response to an endogenous ligand (e.g., estradiol).

[0311] In some aspects, the one or more amino acid substitutions to ligand binding residues include one or more amino acid substitutions within helix 12. Helix 12 of an ER-LBD includes residue positions 533-547 of SEQ ID NO: 1. In some embodiments, the one or more amino acid substitutions within helix 12 are at one or more positions selected from 538, 536, 539, 540, 547, 534, 533, and 537.

[0312] Non-endogenous ligand may refer to, for example, a synthetic estrogen receptor binding ligand that is not naturally expressed by an organism that expresses an estrogen receptor. Non-endogenous estrogen receptor binding ligands include, without limitation, tamoxifen and metabolites thereof, such as 4-hydroxytamoxifen, N-desmethyltamoxifen, tamoxifen-N-oxide, and endoxifen.

[0313] The one or more additional amino acid substitutions may be at one or more positions of SEQ ID NO: 1 selected from 343, 344, 345, 346, 347, 348, 349, 350, 351, 352, 354, 380, 384, 386, 387, 388, 389, 391, 392, 404, 407, 409, 413, 414, 417, 418, 420, 421, 422, 424, 428, 463, 517, 521, 522, 524, 525, 526, 527, 528, 533, 534, 536, 537, 538, 539, 540, and 547. In some embodiments, the one or more additional amino acid substitutions include substitutions at one of the above-listed positions, two of the above-listed positions, three of the above-listed positions, four of the above-listed positions, or five of the above-listed positions.

[0339] A molecular switch may include (a) an inducible cell-death system including a first polypeptide monomer and a second polypeptide monomer, where the first polypeptide monomer and the second polypeptide monomer each include a ligand binding domain and a cell death inducing domain, wherein the first polypeptide monomer and the second polypeptide monomer are configured to oligomerize with each other upon contact with a ligand of the ligand binding domain, thereby generating the cell-death inducing signal in a cell in which the first polypeptide monomer and the second polypeptide monomer are expressed, and where the ligand binding domain includes a modified ER-LBD (such as any of the modified ER-LBDs described herein); and (b) a non-endogenous ligand, where binding of the non-endogenous ligand to the modified ER-LBD induces oligomerization of the first and the second polypeptide monomers, thereby generating the cell-death inducing signal in the cell.

[0340] Also provided herein are inducible cell death systems that include a cell death-inducing domain that is a transcription factor including a nucleic acid-binding domain and a transcriptional effector domain, wherein the transcription factor is configured to generate a cell-death inducing signal by inducing expression of a gene of interest. Transcription factors configured to generate a cell-death inducing signal may include (a) a chimeric transcription factor that includes a modified ER-LBD and is capable of binding to a chimeric transcription factor-responsive promoter (CTF-responsive promoter) operably linked to a gene of interest, and (b) a non-endogenous ligand that binds to the modified ER-LBD of the chimeric protein. Upon binding of the non-endogenous ligand to the modified ER-LBD, the chimeric protein may modulate transcription of a gene of interest.

[0341] In some embodiments, the gene of interest encodes a polypeptide selected from: a caspase domain or derivative or functional fragment thereof, optionally wherein the caspase is selected from any one of caspases 1-11, such as caspase 3, caspase 6, caspase 7, caspase 8, caspase 9, or derivatives or functional fragments thereof, respectively, Diphtheria toxin fragment A (DTA), Bax, Bak, Bok, Bad, Bcl-Xs, Bik, Bcl-2-interacting protein 3 (BNIP3), Fas, Fas-associated protein with death domain (FADD), tumor necrosis factor receptor type 1-associated death domain protein (TRADD), a TNF receptor (TNF-R), APAF-1, granzyme B, second mitochondria-derived activator of caspases (SMAC), Omi, Bmf, Bid, Bim, p53-upregulated modulator of apoptosis (PUMA), Noxa, Blk, Hrk, Cytochrome c, Arts, TNF-related cell death-inducing ligand (TRAIL), Herpes Simplex Virus thymidine kinase (HSV-TK), Varicella Zoster Virus thymidine kinase (VZV-TK), viral Spike protein, Carboxyl esterase, cytosine deaminase, nitroreductase Fksb, Carboxypeptidase G2, Carboxypeptidase A, Horseradish peroxidase, Linamarase, Hepatic cytochrome P450-2B1, or Purine nucleoside phosphorylase.

[0342] In some embodiments, the non-endogenous ligand is selected from 4-hydroxytamoxifen (4-OHT), N-desmethyltamoxifen, tamoxifen-N-oxide, and endoxifen.

[0343] In particular embodiments, the non-endogenous ligand is 4-hydroxytamoxifen (4-OHT, also referred to as afimoxifene). In particular embodiments, the non-endogenous ligand includes a tamoxifen metabolite, such as 4-OHT, endoxifen, or a combination of 4-OHT and endoxifen. In particular embodiments, the non-endogenous ligand is endoxifen.

Isolated Polynucleotides and Heterologous Constructs

[0345] Also provided herein are isolated polynucleotides and heterologous constructs encoding an inducible a modified ER-LBD or chimeric protein (e.g., any of the polypeptides, the first polypeptide monomers, and/or the second polypeptide monomers of the inducible cell death systems herein) as described herein. In some aspects the present disclosure provides an isolated polynucleotide comprising a nucleotide sequence encoding a modified ER-LBD or chimeric protein as described herein. In some aspects, the present disclosure provides a heterologous construct comprising a promoter operatively linked to the polynucleotide encoding the modified ER-LBD or chimeric protein.

[0346] In some aspects, the present disclosure further provides isolated polynucleotides and/or heterologous constructs including a target gene expression cassette.

[0347] Isolated nucleic acid molecule or polynucleotide refers to a nucleic acid molecule, such as DNA or RNA, which has been removed from its native environment. For example, a polynucleotide encoding a modified ER-LBD or chimeric protein contained in a heterologous construct is considered isolated. Further examples of an isolated polynucleotide include recombinant polynucleotides maintained in heterologous host cells or purified (partially or substantially) polynucleotides in solution. An isolated polynucleotide also includes a polynucleotide contained in cells that ordinarily contain the polynucleotide, but the polynucleotide is present extrachromosomally or at a chromosomal location that is different from its natural chromosomal location.

[0348] Isolated polynucleotides include, but are not limited to a cDNA polynucleotide, an RNA polynucleotide, an RNAi oligonucleotide (e.g., siRNAs, miRNAs, antisense oligonucleotides, shRNAs, etc.), an mRNA polynucleotide, a circular plasmid, a linear DNA fragment, a vector, a minicircle, a ssDNA, a bacterial artificial chromosome (BAC), and yeast artificial chromosome (YAC), and an oligonucleotide.

[0349] In some embodiments, the isolated polynucleotide is selected from: a DNA, a cDNA, an RNA, an mRNA, and a naked plasmid (linear or circular).

[0350] By a nucleic acid or polynucleotide having a nucleotide sequence at least, for example, 95% identical to a reference nucleotide sequence of the present invention, it is intended that the nucleotide sequence of the polynucleotide is identical to the reference sequence except that the polynucleotide sequence may include up to five point mutations per each 100 nucleotides of the reference nucleotide sequence. In other words, to obtain a polynucleotide having a nucleotide sequence at least 95% identical to a reference nucleotide sequence, up to 5% of the nucleotides in the reference sequence may be deleted or substituted with another nucleotide, or a number of nucleotides up to 5% of the total nucleotides in the reference sequence may be inserted into the reference sequence. These alterations of the reference sequence may occur at the 5 or 3 terminal positions of the reference nucleotide sequence or anywhere between those terminal positions, interspersed either individually among residues in the reference sequence or in one or more contiguous groups within the reference sequence. As a practical matter, whether any particular polynucleotide sequence is at least 80%, 85%, 90%, 95%, 96%, 97%, 98% or 99% identical to a nucleotide sequence of the present invention can be determined conventionally using known computer programs.

[0351] In some aspects, the chimeric protein encoded by the polynucleotide is a polypeptide of the inducible cell death systems described herein. In some aspects, the chimeric protein encoded by the polynucleotide is a first polypeptide monomer of the inducible cell death systems described herein. In some aspects, the chimeric protein encoded by the polynucleotide is a second polypeptide monomer of the inducible cell death systems described herein. In some aspects, the chimeric protein encoded by the polynucleotide is a first polypeptide monomer and a second polypeptide monomer of the inducible cell death systems described herein. In some aspects, the chimeric protein encoded by the polynucleotide is a chimeric transcription factor, and the polynucleotide further includes a target expression cassette including a gene of interest operably linked to a chimeric transcription factor-responsive (CTF-responsive) promoter. In some embodiments, the target expression cassette is present in the same heterologous construct as the chimeric protein. In some embodiments, the chimeric protein and the target expression cassette are present in separate heterologous constructs.

[0352] The term expression cassette refers to a polynucleotide generated recombinantly or synthetically, with a series of nucleic acid elements that permit transcription of a particular polynucleotide in a target cell. The expression cassette can be incorporated into a plasmid, chromosome, mitochondrial DNA, plastid DNA, virus, or nucleic acid fragment. Typically, the expression cassette portion of an expression vector includes, among other sequences, a nucleic acid sequence to be transcribed and a promoter. In some aspects, the present disclosure provides an expression cassette including a polynucleotide encoding a modified ER-LBD or a chimeric protein including a modified ER-LBD.

[0353] The isolated polynucleotides and heterologous constructs including a modified ER-LBD as described herein are engineered polynucleotides. An engineered polynucleotide is a polynucleotide that does not occur in nature. It should be understood, however, that while an engineered polynucleotide as a whole is not naturally-occurring, it may include nucleotide sequences that occur in nature. In some embodiments, an engineered polynucleotide comprises nucleotide sequences from different organisms (e.g., from different species). For example, in some embodiments, an engineered polynucleotide includes a murine nucleotide sequence, a bacterial nucleotide sequence, a human nucleotide sequence, and/or a viral nucleotide sequence. The term engineered polynucleotide includes recombinant nucleic acids and synthetic nucleic acids. A recombinant polynucleotide refers to a molecule that is constructed by joining nucleotide molecules and, in some embodiments, can replicate in a live cell. A synthetic polynucleotide refers to a molecule that is amplified or chemically, or by other means, synthesized. Synthetic polynucleotides include those that are chemically modified, or otherwise modified, but can base pair with naturally-occurring nucleotide molecules. Modifications include, but are not limited to, one or more modified internucleotide linkages and non-natural nucleic acids. Modifications are described in further detail in U.S. Pat. No. 6,673,611 and U.S. Application Publication 2004/0019001 and, each of which is incorporated by reference in their entirety. Modified internucleotide linkages can be a phosphorodithioate or phosphorothioate linkage. Non-natural nucleic acids can be a locked nucleic acid (LNA), a peptide nucleic acid (PNA), glycol nucleic acid (GNA), a phosphorodiamidate morpholino oligomer (PMO or morpholino), and threose nucleic acid (TNA). Non-natural nucleic acids are described in further detail in International Application WO 1998/039352, U.S. Application Pub. No. 2013/0156849, and U.S. Pat. Nos. 6,670,461; 5,539,082; 5,185,444, each herein incorporated by reference in their entirety. Recombinant polynucleotides and synthetic polynucleotides also include those molecules that result from the replication of either of the foregoing. Engineered polynucleotides of the present disclosure may be encoded by a single molecule (e.g., included in the same plasmid or other vector) or by multiple different molecules (e.g., multiple different independently-replicating molecules).

[0354] Engineered polynucleotides of the present disclosure may be produced using standard molecular biology methods (see, e.g., Green and Sambrook, Molecular Cloning, A Laboratory Manual, 2012, Cold Spring Harbor Press). In some embodiments, engineered nucleic acid constructs are produced using GIBSON ASSEMBLY Cloning (see, e.g., Gibson, D. G. et al. Nature Methods, 343-345, 2009; and Gibson, D. G. et al. Nature Methods, 901-903, 2010, each of which is incorporated by reference herein). GIBSON ASSEMBLY typically uses three enzymatic activities in a single-tube reaction: 5 exonuclease, the Y extension activity of a DNA polymerase and DNA ligase activity. The 5 exonuclease activity chews back the 5 end sequences and exposes the complementary sequence for annealing. The polymerase activity then fills in the gaps on the annealed regions. A DNA ligase then seals the nick and covalently links the DNA fragments together. The overlapping sequence of adjoining fragments is much longer than those used in Golden Gate Assembly, and therefore results in a higher percentage of correct assemblies. In some embodiments, engineered nucleic acid constructs are produced using IN-FUSION cloning (Clontech).

[0355] In some embodiments, the polynucleotides as described herein are included in a heterologous construct. The term vector or expression vector is synonymous with heterologous construct and refers to a polynucleotide that is used to introduce and direct the expression of one or more genes that are operably associated with the construct in a target cell. The term includes the construct as a self-replicating nucleic acid structure as well as the vector incorporated into the genome of a host cell into which it has been introduced. A heterologous construct as described herein includes an expression cassette. In some aspects, provided herein is a heterologous construct comprising an expression cassette that comprises a promoter operably linked to a polynucleotide that encodes a modified ER-LBD or a chimeric protein including a modified ER-LBD.

[0356] As used herein, a promoter refers to a control region of a nucleic acid sequence at which initiation and rate of transcription of the remainder of a nucleic acid sequence are controlled. A promoter may also contain sub-regions at which regulatory proteins and molecules may bind, such as RNA polymerase and other transcription factors. Promoters may be constitutive, inducible, repressible, tissue-specific or any combination thereof. A promoter drives expression or drives transcription of the nucleic acid sequence that it regulates. Herein, a promoter is considered to be operably linked when it is in a correct functional location and orientation in relation to a nucleic acid sequence it regulates to control (drive) transcriptional initiation and/or expression of that sequence.

[0357] A promoter may be one naturally associated with a gene or sequence, as may be obtained by isolating the 5 non-coding sequences located upstream of the coding segment of a given gene or sequence. Such a promoter can be referred to as endogenous. In some embodiments, a coding nucleic acid sequence may be positioned under the control of a recombinant or heterologous promoter, which refers to a promoter that is not normally associated with the encoded sequence in its natural environment. Such promoters may include promoters of other genes; promoters isolated from any other cell; and synthetic promoters or enhancers that are not naturally occurring such as, for example, those that contain different elements of different transcriptional regulatory regions and/or mutations that alter expression through methods of genetic engineering that are known in the art. In addition to producing nucleic acid sequences of promoters and enhancers synthetically, sequences may be produced using recombinant cloning and/or nucleic acid amplification technology, including polymerase chain reaction (PCR) (see, e.g., U.S. Pat. Nos. 4,683,202 and 5,928,906).

[0358] As used herein, an inducible promoter refers to a promoter characterized by regulating (e.g., initiating or activating) transcriptional activity when in the presence of, influenced by or contacted by a signal. The signal may be endogenous or a normally exogenous condition (e.g., light), compound (e.g., chemical or non-chemical compound) or protein (e.g., a chimeric transcription factor as described herein) that contacts an inducible promoter in such a way as to be active in regulating transcriptional activity from the inducible promoter. Activation of transcription may involve directly acting on a promoter to drive transcription or indirectly acting on a promoter by inactivation a repressor that is preventing the promoter from driving transcription. Conversely, deactivation of transcription may involve directly acting on a promoter to prevent transcription or indirectly acting on a promoter by activating a repressor that then acts on the promoter.

[0359] As used herein, a promoter is responsive to or modulated by a local tumor state (e.g., inflammation or hypoxia) or signal if in the presence of that state or signal, transcription from the promoter is activated, deactivated, increased, or decreased. In some embodiments, the promoter comprises a response element. A response element is a short sequence of DNA within a promoter region that binds specific molecules (e.g., transcription factors) that modulate (regulate) gene expression from the promoter. Response elements that may be used in accordance with the present disclosure include, without limitation, a phloretin-adjustable control element (PEACE), a zinc-finger DNA binding domain (DBD), an interferon-gamma-activated sequence (GAS) (Decker, T. et al. J Interferon Cytokine Res. 1997 March; 17 (3): 121-34, incorporated herein by reference), an interferon-stimulated response element (ISRE) (Han, K. J. et al. J Biol Chem. 2004 Apr. 9; 279 (15): 15652-61, incorporated herein by reference), a NF-kappaB response element (Wang, V. et al. Cell Reports. 2012; 2 (4): 824-839, incorporated herein by reference), and a STAT3 response element (Zhang, D. et al. J of Biol Chem. 1996; 271:9503-9509, incorporated herein by reference). Other response elements are encompassed herein. Response elements can also contain tandem repeats (e.g., consecutive repeats of the same nucleotide sequence encoding the response element) to generally increase sensitivity of the response element to its cognate binding molecule. Tandem repeats can be labeled 2, 3, 4, 5, etc. to denote the number of repeats present.

[0360] Non-limiting examples of responsive promoters (also referred to as inducible promoters) (e.g., TGF-beta responsive promoters) are listed in Table 3, which shows the design of the promoter and transcription factor, as well as the effect of the inducer molecule towards the transcription factor (TF) and transgene transcription (T) is shown (B, binding; D, dissociation; n.d., not determined) (A, activation; DA, deactivation; DR, derepression) (see Horner, M. & Weber, W. FEBS Letters 586 (2012) 20784-2096m, and references cited therein). Non-limiting examples of components of inducible promoters include those shown in Table 4.

[0365] In some embodiments, engineered polynucleotides or constructs of the present disclosure are configured to produce multiple polypeptides. For example, polynucleotides may be configured to produce 2 different polypeptides. The polynucleotide may be configured to produce a polypeptide including polypeptides of the inducible cell death systems including a modified ER-LBD described herein, e.g., a first polypeptide monomer and/or a second polypeptide monomer that each include the modified ER-LBD and a cell death inducing domain.

[0366] In some embodiments, polypeptides of the inducible cell death systems including a modified ER-LBD described herein, e.g., a first polypeptide monomer and/or a second polypeptide monomer that each include the modified ER-LBD and a cell death inducing domain, may be encoded by the same polynucleotide or heterologous construct.

[0367] In some embodiments, engineered nucleic acids can be multicistronic, i.e., more than one separate polypeptide (e.g., multiple exogenous polypeptides, such as a first polypeptide monomer and a second polypeptide monomer that each include the modified ER-LBD and a cell death inducing domain) can be produced from a single transcript. Engineered nucleic acids can be multicistronic through the use of various linkers, e.g., a polynucleotide sequence encoding a first exogenous polynucleotide can be linked to a nucleotide sequence encoding a second exogenous polynucleotide, such as in a first gene: linker: second gene 5 to 3 orientation. A linker polynucleotide sequence can encode one or more 2A ribosome skipping elements, such as T2A. Other 2A ribosome skipping elements include, but are not limited to, E2A, P2A, and F2A. 2A ribosome skipping elements allow production of separate polypeptides encoded by the first and second genes are produced during translation. A linker can encode a cleavable linker polypeptide sequence, such as a Furin cleavage site or a TEV cleavage site, wherein following expression the cleavable linker polypeptide is cleaved such that separate polypeptides encoded by the first and second genes are produced. A cleavable linker can include a polypeptide sequence, such as such a flexible linker (e.g., a Gly-Ser-Gly sequence), that further promotes cleavage.

[0368] A linker can encode an Internal Ribosome Entry Site (IRES), such that separate polypeptides encoded by the first and second genes are produced during translation. A linker can encode a splice acceptor, such as a viral splice acceptor.

[0369] A linker can be a combination of linkers, such as a Furin-2A linker that can produce separate polypeptides through 2A ribosome skipping followed by further cleavage of the Furin site to allow for complete removal of 2A residues. In some embodiments, a combination of linkers can include a Furin sequence, a flexible linker, and 2A linker. Accordingly, in some embodiments, the linker is a Furin-Gly-Ser-Gly-2A fusion polypeptide. In some embodiments, a linker is a Furin-Gly-Ser-Gly-T2A fusion polypeptide.

[0370] In general, a multicistronic system can use any number or combination of linkers, to express any number of genes or portions thereof (e.g., an engineered nucleic acid can encode a first, a second, and a third polypeptide molecule, each separated by linkers such that separate polypeptides encoded by the first, second, and third polypeptides are produced).

[0371] Linkers, as used herein, can refer to polypeptides that link a first polypeptide sequence and a second polypeptide sequence or the multicistronic linkers described above.

Expression Systems Further Including a Target Expression Cassette

[0372] In some aspects, the chimeric protein is a chimeric transcription factor and the present disclosure further provides a target expression cassette including a chimeric transcription factor-responsive (CTF-responsive) promoter. For example, chimeric transcription factors having modified ER-LDBs may be used to regulate expression of pro-cell-death/apoptotic factors (e.g., a polypeptide including a cell death-inducing domain), cell survival polypeptides, inhibitors of pro-apoptotic factors, and/or inhibitors of cell survival polypeptides.

[0373] Target expression cassette refers to an expression cassette including a gene with chimeric transcription factor-controllable expression. The expression is controlled by the chimeric transcription factor based on the presence of a non-endogenous ligand (e.g., 4-OHT or endoxifen).

[0374] In some aspects, the present disclosure provides polynucleotides encoding a gene of interest operably linked to a chimeric transcription factor-responsive promoter (CTF-responsive promoter). CTF-responsive promoters are synthetic, inducible promoters that are responsive to a chimeric transcription factor including a modified ER-LBD, and are inducible in response to a non-endogenous ligand such as 4-OHT.

[0375] In some embodiments, the CTF-responsive promoter comprises a core promoter sequence and a binding domain that binds to a chimeric transcription factor as described herein.

[0376] The binding domain may include one or more zinc finger binding sites. The binding domain can comprise 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more zinc finger binding sites. In some embodiments, the binding domain comprises one zinc finger binding site. In some embodiments, the binding domain comprises two zinc finger binding sites. In some embodiments, the binding domain comprises three zinc finger binding sites. In some embodiments, the binding domain comprises four zinc finger binding sites. An exemplary binding domain comprising zinc finger binding sites is shown in the sequence:

[0377] The core promoter sequence may include a minimal promoter. Examples of minimal promoters include minP, minCMV, YB_TATA, and minTK.

[0378] In some aspects, the chimeric protein including the modified ER-LBD is a chimeric transcription factor, and the heterologous construct further includes a target expression cassette including a chimeric-transcription factor responsive promoter. In some aspects, provided herein is a first heterologous construct comprising an expression cassette that comprises a polynucleotide that encodes chimeric transcription factor including a modified ER-LBD, and a second heterologous construct comprising a target expression cassette including a chimeric transcription factor-responsive (CTF-responsive) promoter.

Post-Transcriptional Regulatory Elements

[0379] In some embodiments, an engineered nucleic acid of the present disclosure comprises a post-transcriptional regulatory element (PRE). PREs can enhance gene expression via enabling tertiary RNA structure stability and 3 end formation. Non-limiting examples of PREs include the Hepatitis B virus PRE (HPRE) and the Woodchuck Hepatitis Virus PRE (WPRE). In some embodiments, the post-transcriptional regulatory element is a Woodchuck Hepatitis Virus Posttranscriptional Regulatory Element (WPRE). In some embodiments, the WPRE comprises the alpha, beta, and gamma components of the WPRE element. In some embodiments, the WPRE comprises the alpha component of the WPRE element. Examples of WPRE sequences include SEQ ID NO: 38 and SEQ ID NO: 39.

Engineered Cells

[0380] Also provided herein are cells, and methods of producing cells, that comprise one or more polynucleotides or constructs of the present disclosure. These cells are referred to herein as engineered cells. These cells, which typically contain one or more engineered nucleic acids, do not occur in nature. In some embodiments, the cells are isolated cells that recombinantly express the one or more engineered polynucleotides. In some embodiments, the engineered polynucleotides are expressed from one or more vectors or a selected locus from the genome of the cell. In some embodiments, the cells are engineered to include a polynucleotide comprising a promoter operably linked to a nucleotide sequence.

[0381] An engineered cell of the present disclosure can comprise an engineered polynucleotide integrated into the cell's genome. An engineered cell can comprise an engineered polynucleotide capable of expression without integrating into the cell's genome, for example, engineered with a transient expression system such as a plasmid or mRNA.

Engineered Cell Types

[0382] An engineered cell of the present disclosure can be a human cell. An engineered cell can be a human primary cell. An engineered primary cell can be any somatic cell. An engineered primary cell can be any stem cell. In some embodiments, the engineered cell is derived from the subject. In some embodiments, the engineered cell is allogeneic with reference to the subject.

[0383] An engineered cell of the present disclosure can be isolated from a subject, such as a subject known or suspected to have cancer. Cell isolation methods are known to those skilled in the art and include, but are not limited to, sorting techniques based on cell-surface marker expression, such as FACS sorting, positive isolation techniques, and negative isolation, magnetic isolation, and combinations thereof. An engineered cell can be allogenic with reference to the subject being administered a treatment. Allogenic modified cells can be HLA-matched to the subject being administered a treatment.

One skilled in the art will recognize that culturing conditions will depend on the specific downstream use of the engineered cell, for example, specific culturing conditions for subsequent administration of the engineered cell to a subject.

Methods of Engineering Cells

[0388] Also provided herein are compositions and methods for engineering cells with any polynucleotide or construct as described herein.

[0389] In general, cells are engineered through introduction (i.e., delivery) of one or more polynucleotides of the present disclosure. Delivery methods include, but are not limited to, viral-mediated delivery, lipid-mediated transfection, nanoparticle delivery, electroporation, sonication, and cell membrane deformation by physical means. One skilled in the art will appreciate the choice of delivery method can depend on the specific cell type to be engineered.

Viral-Mediated Delivery

[0390] Viral vector-based delivery platforms can be used to engineer cells. In general, a viral vector-based delivery platform engineers a cell through introducing (i.e., delivering) into a host cell. For example, a viral vector-based delivery platform can engineer a cell through introducing any of the engineered nucleic acids described herein. A viral vector-based delivery platform can be a nucleic acid, and as such, an engineered nucleic acid can also encompass an engineered virally derived nucleic acid. Such engineered virally derived nucleic acids can also be referred to as recombinant viruses or engineered viruses.

[0391] A viral vector-based delivery platform can encode more than one engineered nucleic acid, gene, or transgene within the same nucleic acid. For example, an engineered virally derived nucleic acid, e.g., a recombinant virus or an engineered virus, can encode one or more transgenes, including, but not limited to, any of the engineered nucleic acids described herein. The one or more transgenes can be configured to express polypeptides described herein (e.g., inducible cell death systems including a modified ER-LBD). A viral vector-based delivery platform can encode one or more genes in addition to the transgene encoding the modified ER-LBD, such as viral genes needed for viral infectivity and/or viral production (e.g., capsid proteins, envelope proteins, viral polymerases, viral transcriptases, etc.), referred to as cis-acting elements or genes.

[0392] A viral vector-based delivery platform can comprise more than one viral vector, such as separate viral vectors encoding the engineered nucleic acids, genes, or transgenes described herein, and referred to as trans-acting elements or genes. For example, a helper-dependent viral vector-based delivery platform can provide additional genes needed for viral infectivity and/or viral production on one or more additional separate vectors in addition to the vector encoding the modified ER-LBD. One viral vector can deliver more than one engineered polynucleotides, such as one vector that delivers an engineered polynucleotide configured to produce a modified ER-LBD and an engineered polynucleotide configured produce a gene of interest. More than one viral vector can deliver more than one engineered nucleic acids, such as a first vector that delivers an engineered polynucleotide configured to produce a modified ER-LBD and a second vector that delivers an additional engineered polynucleotide. The number of viral vectors used can depend on the packaging capacity of the above-mentioned viral vector-based vaccine platforms, and one skilled in the art can select the appropriate number of viral vectors.

[0393] In general, any of the viral vector-based systems can be used for the in vitro production of molecules, or used in vivo and ex vivo gene therapy procedures, e.g., for in vivo delivery. The selection of an appropriate viral vector-based system will depend on a variety of factors, such as cargo/payload size, immunogenicity of the viral system, target cell of interest, gene expression strength and timing, and other factors appreciated by one skilled in the art.

[0394] Viral vector-based delivery platforms can be RNA-based viruses or DNA-based viruses. Exemplary viral vector-based delivery platforms include, but are not limited to, a herpes simplex virus, an adenovirus, a measles virus, an influenza virus, a Indiana vesiculovirus, a Newcastle disease virus, a vaccinia virus, a poliovirus, a myxoma virus, a reovirus, a mumps virus, a Maraba virus, a rabies virus, a rotavirus, a hepatitis virus, a rubella virus, a dengue virus, a chikungunya virus, a respiratory syncytial virus, a lymphocytic choriomeningitis virus, a morbillivirus, a lentivirus, a replicating retrovirus, a rhabdovirus, a Seneca Valley virus, a sindbis virus, and any variant or derivative thereof. Other exemplary viral vector-based delivery platforms are described in the art, such as vaccinia, fowlpox, self-replicating alphavirus, marabavirus, adenovirus (See, e.g., Tatsis et al., Adenoviruses, Molecular Therapy (2004) 10, 616-629), or lentivirus, including but not limited to second, third or hybrid second/third generation lentivirus and recombinant lentivirus of any generation designed to target specific cell types or receptors (See, e.g., Hu et al., Immunization Delivered by Lentiviral Vectors for Cancer and Infectious Diseases, Immunol Rev. (2011) 239 (1): 45-61, Sakuma et al., Lentiviral vectors: basic to translational, Biochem J. (2012) 443 (3): 603-18, Cooper et al., Rescue of splicing-mediated intron loss maximizes expression in lentiviral vectors containing the human ubiquitin C promoter, Nucl. Acids Res. (2015) 43 (1): 682-690, Zufferey et al., Self-Inactivating Lentivirus Vector for Safe and Efficient In vivo Gene Delivery, J. Virol. (1998) 72 (12): 9873-9880).

[0395] The sequences may be preceded with one or more sequences targeting a subcellular compartment. Upon introduction (i.e., delivery) into a host cell, infected cells (i.e., an engineered cell) can express, and in some case secrete, the modified ER-LBD (or chimeric polypeptide including the modified ER-LBD). Vaccinia vectors and methods useful in immunization protocols are described in, e.g., U.S. Pat. No. 4,722,848. Another vector is BCG (Bacille Calmette Guerin). BCG vectors are described in Stover et al. (Nature 351:456-460 (1991)). A wide variety of other vectors useful for the introduction (i.e., delivery) of engineered nucleic acids, e.g., Salmonella typhi vectors, and the like will be apparent to those skilled in the art from the description herein.

[0396] The viral vector-based delivery platforms can be a virus that targets a tumor cell, herein referred to as an oncolytic virus. Examples of oncolytic viruses include, but are not limited to, an oncolytic herpes simplex virus, an oncolytic adenovirus, an oncolytic measles virus, an oncolytic influenza virus, an oncolytic Indiana vesiculovirus, an oncolytic Newcastle disease virus, an oncolytic vaccinia virus, an oncolytic poliovirus, an oncolytic myxoma virus, an oncolytic reovirus, an oncolytic mumps virus, an oncolytic Maraba virus, an oncolytic rabies virus, an oncolytic rotavirus, an oncolytic hepatitis virus, an oncolytic rubella virus, an oncolytic dengue virus, an oncolytic chikungunya virus, an oncolytic respiratory syncytial virus, an oncolytic lymphocytic choriomeningitis virus, an oncolytic morbillivirus, an oncolytic lentivirus, an oncolytic replicating retrovirus, an oncolytic rhabdovirus, an oncolytic Seneca Valley virus, an oncolytic sindbis virus, and any variant or derivative thereof. Any of the oncolytic viruses described herein can be a recombinant oncolytic virus comprising one more transgenes (e.g., an engineered nucleic acid described herein). The transgenes can be configured to express a modified ER-LBD (or chimeric polypeptide including the modified ER-LBD) and optionally a gene of interest.

[0397] In some embodiments, the virus is selected from: a lentivirus, a retrovirus, an oncolytic virus, an adenovirus, an adeno-associated virus (AAV), and a virus-like particle (VLP).

[0398] The viral vector-based delivery platform can be retrovirus-based. In general, retroviral vectors are comprised of cis-acting long terminal repeats with packaging capacity for up to 6-10 kb of foreign sequence. The minimum cis-acting LTRs are sufficient for replication and packaging of the vectors, which are then used to integrate the one or more engineered nucleic acids (e.g., a transgene encoding the modified ER-LBD) into the target cell to provide permanent transgene expression. Retroviral-based delivery systems include, but are not limited to, those based upon murine leukemia, virus (MuLV), gibbon ape leukemia virus (GaLV), Simian Immunodeficiency virus (SIV), human immunodeficiency virus (HIV), and combinations thereof (see, e.g., Buchscher et al., J. Virol. 66:2731-2739 (1992); Johann et ah, J. Virol. 66:1635-1640 (1992); Sommnerfelt et al., Virol. 176:58-59 (1990); Wilson et ah, J. Virol. 63:2374-2378 (1989); Miller et al, J, Virol. 65:2220-2224 (1991); PCT/US94/05700). Other retroviral systems include the Phoenix retrovirus system.

[0399] The viral vector-based delivery platform can be lentivirus-based. In general, lentiviral vectors are retroviral vectors that are able to transduce or infect non-dividing cells and typically produce high viral titers. Lentiviral-based delivery platforms can be HIV-based, such as ViraPower systems (ThermoFisher) or pLenti systems (Cell Biolabs). Lentiviral-based delivery platforms can be SIV, or FIV-based. Other exemplary lentivirus-based delivery platforms are described in more detail in U.S. Pat. Nos. 7,311,907; 7,262,049; 7,250,299; 7,226,780; 7,220,578; 7,211,247; 7,160,721; 7,078,031; 7,070,993; 7,056,699; 6,955,919, each herein incorporated by reference for all purposes.

[0400] The viral vector-based delivery platform can be adenovirus-based. In general, adenoviral based vectors are capable of very high transduction efficiency in many cell types, do not require cell division, achieve high titer and levels of expression, and can be produced in large quantities in a relatively simple system. In general, adenoviruses can be used for transient expression of a transgene within an infected cell since adenoviruses do not typically integrate into a host's genome. Adenovirus-based delivery platforms are described in more detail in Li et al., Invest Opthalmol Vis Sci 35:2543 2549, 1994; Borras et al., Gene Ther 6:515 524, 1999; Li and Davidson, PNAS 92:7700 7704, 1995; Sakamoto et al., H Gene Ther 5:1088 1097, 1999; WO 94/12649, WO 93/03769; WO 93/19191; WO 94/28938; WO 95/11984 and WO 95/00655, each herein incorporated by reference for all purposes. Other exemplary adenovirus-based delivery platforms are described in more detail in U.S. Pat. Nos. 5,585,362; 6,083,716, 7,371,570; 7,348,178; 7,323,177; 7,319,033; 7,318,919; and 7,306,793 and International Patent Application WO96/13597, each herein incorporated by reference for all purposes.

[0401] The viral vector-based delivery platform can be adeno-associated virus (AAV)-based. Adeno-associated virus (AAV) vectors may be used to transduce cells with engineered nucleic acids (e.g., any of the engineered nucleic acids described herein). AAV systems can be used for the in vitro production of a modified ER-LBD (or chimeric polypeptide including the modified ER-LBD), or used in vivo and ex vivo gene therapy procedures, e.g., for in vivo delivery of the modified ER-LBD (see, e.g., West et al., Virology 160:38-47 (1987); U.S. Pat. Nos. 4,797,368; 5,436,146; 6,632,670; 6,642,051; 7,078,387; 7,314,912; 6,498,244; 7,906,111; US patent publications US 2003-0138772, US 2007/0036760, and US 2009/0197338; Gao, et al., J. Virol, 78 (12): 6381-6388 (June 2004); Gao, et al, Proc Natl Acad Sci USA, 100 (10): 6081-6086 (May 13, 2003); and International Patent applications WO 2010/138263 and WO 93/24641; Kotin, Human Gene Therapy 5:793-801 (1994); Muzyczka, J. Clin. Invest. 94:1351 (1994), each herein incorporated by reference for all purposes). Exemplary methods for constructing recombinant AAV vectors are described in more detail in U.S. Pat. No. 5,173,414; Tratschin et ah, Mol. Cell. Biol. 5:3251-3260 (1985); Tratschin, et ah, Mol. Cell, Biol. 4:2072-2081 (1984); Hermonat & Muzyczka, PNAS 81:64666470 (1984); and Samuiski et ah, J. Virol. 63:03822-3828 (1989), each herein incorporated by reference for all purposes. In general, an AAV-based vector comprises a capsid protein having an amino acid sequence corresponding to any one of AAV1, AAV2, AAV3, AAV4, AAV5, AAV6, AAV7, AAV8, AAV9, AAV.Rh10, AAV11 and variants thereof.

[0402] The viral vector-based delivery platform can be a virus-like particle (VLP) platform. In general, VLPs are constructed by producing viral structural proteins and purifying resulting viral particles. Then, following purification, a cargo/payload (e.g., any of the engineered nucleic acids described herein) is encapsulated within the purified particle ex vivo. Accordingly, production of VLPs maintains separation of the nucleic acids encoding viral structural proteins and the nucleic acids encoding the cargo/payload. The viral structural proteins used in VLP production can be produced in a variety of expression systems, including mammalian, yeast, insect, bacterial, or in vivo translation expression systems. The purified viral particles can be denatured and reformed in the presence of the desired cargo to produce VLPs using methods known to those skilled in the art. Production of VLPs are described in more detail in Seow et al. (Mol Ther. 2009 May; 17 (5): 767-777), herein incorporated by reference for all purposes.

[0403] The viral vector-based delivery platform can be engineered to target (i.e., infect) a range of cells, target a narrow subset of cells, or target a specific cell. In general, the envelope protein chosen for the viral vector-based delivery platform will determine the viral tropism. The virus used in the viral vector-based delivery platform can be pseudotyped to target a specific cell of interest. The viral vector-based delivery platform can be pantropic and infect a range of cells. For example, pantropic viral vector-based delivery platforms can include the VSV-G envelope. The viral vector-based delivery platform can be amphotropic and infect mammalian cells. Accordingly, one skilled in the art can select the appropriate tropism, pseudotype, and/or envelope protein for targeting a desired cell type.

Lipid Structure Delivery Systems

[0404] Engineered nucleic acids of the present disclosure (e.g., a nucleic acid encoding a modified ER-LBD or chimeric protein described herein) can be introduced into a cell using a lipid-mediated delivery system. In general, a lipid-mediated delivery system uses a structure composed of an outer lipid membrane enveloping an internal compartment. Examples of lipid-based structures include, but are not limited to, a lipid-based nanoparticle, a liposome, a micelle, an exosome, a vesicle, an extracellular vesicle, a cell, or a tissue. Lipid structure delivery systems can deliver a cargo/payload (e.g., any of the engineered nucleic acids described herein) in vitro, in vivo, or ex vivo.

[0405] A lipid-based nanoparticle can include, but is not limited to, a unilamellar liposome, a multilamellar liposome, and a lipid preparation. As used herein, a liposome is a generic term encompassing in vitro preparations of lipid vehicles formed by enclosing a desired cargo, e.g., an engineered nucleic acid, such as any of the engineered nucleic acids described herein, within a lipid shell or a lipid aggregate. Liposomes may be characterized as having vesicular structures with a bilayer membrane, generally comprising a phospholipid, and an inner medium that generally comprises an aqueous composition. Liposomes include, but are not limited to, emulsions, foams, micelles, insoluble monolayers, liquid crystals, phospholipid dispersions, lamellar layers and the like. Liposomes can be unilamellar liposomes. Liposomes can be multilamellar liposomes. Liposomes can be multivesicular liposomes. Liposomes can be positively charged, negatively charged, or neutrally charged. In certain embodiments, the liposomes are neutral in charge. Liposomes can be formed from standard vesicle-forming lipids, which generally include neutral and negatively charged phospholipids and a sterol, such as cholesterol. The selection of lipids is generally guided by consideration of a desired purpose, e.g., criteria for in vivo delivery, such as liposome size, acid lability and stability of the liposomes in the blood stream. A variety of methods are available for preparing liposomes, as described in, e.g., Szoka et al., Ann. Rev. Biophys. Bioeng. 9; 467 (1980), U.S. Pat. Nos. 4,235,871, 4,501,728, 4,501,728, 4,837,028, and 5,019,369, each herein incorporated by reference for all purposes.

[0406] A multilamellar liposome is generated spontaneously when lipids comprising phospholipids are suspended in an excess of aqueous solution such that multiple lipid layers are separated by an aqueous medium. Water and dissolved solutes are entrapped in closed structures between the lipid bilayers following the lipid components undergoing self-rearrangement. A desired cargo (e.g., a polypeptide, a nucleic acid, a small molecule drug, an engineered nucleic acid, such as any of the engineered nucleic acids described herein, a viral vector, a viral-based delivery system, etc.) can be encapsulated in the aqueous interior of a liposome, attached to a liposome via a linking molecule that is associated with both the liposome and the polypeptide/nucleic acid, interspersed within the lipid bilayer of a liposome, entrapped in a liposome, complexed with a liposome, or otherwise associated with the liposome such that it can be delivered to a target entity. Lipophilic molecules or molecules with lipophilic regions may also dissolve in or associate with the lipid bilayer.

[0407] A liposome used according to the present embodiments can be made by different methods, as would be known to one of ordinary skill in the art. Preparations of liposomes are described in further detail in WO 2016/201323, International Applications PCT/US85/01161 and PCT/US89/05040, and U.S. Pat. Nos. 4,728,578, 4,728,575, 4,737,323, 4,533,254, 4,162,282, 4,310,505, and 4,921,706; each herein incorporated by reference for all purposes.

[0408] Liposomes can be cationic liposomes. Examples of cationic liposomes are described in more detail in U.S. Pat. Nos. 5,962,016; 5,030,453; 6,680,068, U.S. Application 2004/0208921, and International Patent Applications WO03/015757A1, WO04029213A2, and WO02/100435A1, each hereby incorporated by reference in their entirety.

[0409] Lipid-mediated gene delivery methods are described, for instance, in WO 96/18372; WO 93/24640; Mannino & Gould-Fogerite, BioTechniques 6 (7): 682-691 (1988); U.S. Pat. No. 5,279,833 Rose U.S. Pat. No. 5,279,833; WO91/06309; and Felgner et al., Proc. Natl. Acad. Sci. USA 84:7413-7414 (1987), each herein incorporated by reference for all purposes.

[0410] Exosomes are small membrane vesicles of endocytic origin that are released into the extracellular environment following fusion of multivesicular bodies with the plasma membrane. The size of exosomes ranges between 30 and 100 nm in diameter. Their surface consists of a lipid bilayer from the donor cell's cell membrane, and they contain cytosol from the cell that produced the exosome, and exhibit membrane proteins from the parental cell on the surface. Exosomes useful for the delivery of nucleic acids are known to those skilled in the art, e.g., the exosomes described in more detail in U.S. Pat. No. 9,889,210, herein incorporated by reference for all purposes.

[0411] As used herein, the term extracellular vesicle or EV refers to a cell-derived vesicle comprising a membrane that encloses an internal space. In general, extracellular vesicles comprise all membrane-bound vesicles that have a smaller diameter than the cell from which they are derived. Generally extracellular vesicles range in diameter from 20 nm to 1000 nm, and can comprise various macromolecular cargo either within the internal space, displayed on the external surface of the extracellular vesicle, and/or spanning the membrane. The cargo can comprise nucleic acids (e.g., any of the engineered nucleic acids described herein), proteins, carbohydrates, lipids, small molecules, and/or combinations thereof. By way of example and without limitation, extracellular vesicles include apoptotic bodies, fragments of cells, vesicles derived from cells by direct or indirect manipulation (e.g., by serial extrusion or treatment with alkaline solutions), vesiculated organelles, and vesicles produced by living cells (e.g., by direct plasma membrane budding or fusion of the late endosome with the plasma membrane). Extracellular vesicles can be derived from a living or dead organism, explanted tissues or organs, and/or cultured cells.

[0412] As used herein the term exosome refers to a cell-derived small (between 20-300 nm in diameter, more preferably 40-200 nm in diameter) vesicle comprising a membrane that encloses an internal space, and which is generated from the cell by direct plasma membrane budding or by fusion of the late endosome with the plasma membrane. The exosome comprises lipid or fatty acid and polypeptide and optionally comprises a payload (e.g., a therapeutic agent), a receiver (e.g., a targeting moiety), a polynucleotide (e.g., a nucleic acid, RNA, or DNA, such as any of the engineered nucleic acids described herein), a sugar (e.g., a simple sugar, polysaccharide, or glycan) or other molecules. The exosome can be derived from a producer cell, and isolated from the producer cell based on its size, density, biochemical parameters, or a combination thereof. An exosome is a species of extracellular vesicle. Generally, exosome production/biogenesis does not result in the destruction of the producer cell. Exosomes and preparation of exosomes are described in further detail in WO 2016/201323, which is hereby incorporated by reference in its entirety.

[0413] As used herein, the term nanovesicle (also referred to as a microvesicle) refers to a cell-derived small (between 20-250 nm in diameter, more preferably 30-150 nm in diameter) vesicle comprising a membrane that encloses an internal space, and which is generated from the cell by direct or indirect manipulation such that said nanovesicle would not be produced by said producer cell without said manipulation. In general, a nanovesicle is a sub-species of an extracellular vesicle. Appropriate manipulations of the producer cell include but are not limited to serial extrusion, treatment with alkaline solutions, sonication, or combinations thereof. The production of nanovesicles may, in some instances, result in the destruction of said producer cell. Preferably, populations of nanovesicles are substantially free of vesicles that are derived from producer cells by way of direct budding from the plasma membrane or fusion of the late endosome with the plasma membrane. The nanovesicle comprises lipid or fatty acid and polypeptide, and optionally comprises a payload (e.g., a therapeutic agent), a receiver (e.g., a targeting moiety), a polynucleotide (e.g., a nucleic acid, RNA, or DNA, such as any of the engineered nucleic acids described herein), a sugar (e.g., a simple sugar, polysaccharide, or glycan) or other molecules. The nanovesicle, once it is derived from a producer cell according to said manipulation, may be isolated from the producer cell based on its size, density, biochemical parameters, or a combination thereof.

[0414] Lipid nanoparticles (LNPs), in general, are synthetic lipid structures that rely on the amphiphilic nature of lipids to form membranes and vesicle like structures (Riley 2017). In general, these vesicles deliver cargo/payloads, such as any of the engineered nucleic acids or viral systems described herein, by absorbing into the membrane of target cells and releasing the cargo into the cytosol. Lipids used in LNP formation can be cationic, anionic, or neutral. The lipids can be synthetic or naturally derived, and in some instances biodegradable. Lipids can include fats, cholesterol, phospholipids, lipid conjugates including, but not limited to, polyethyleneglycol (PEG) conjugates (PEGylated lipids), waxes, oils, glycerides, and fat soluble vitamins. Lipid compositions generally include defined mixtures of materials, such as the cationic, neutral, anionic, and amphipathic lipids. In some instances, specific lipids are included to prevent LNP aggregation, prevent lipid oxidation, or provide functional chemical groups that facilitate attachment of additional moieties. Lipid composition can influence overall LNP size and stability. In an example, the lipid composition comprises dilinoleylmethyl-4-dimethylaminobutyrate (MC3) or MC3-like molecules. MC3 and MC3-like lipid compositions can be formulated to include one or more other lipids, such as a PEG or PEG-conjugated lipid, a sterol, or neutral lipids. In addition, LNPs can be further engineered or functionalized to facilitate targeting of specific cell types. Another consideration in LNP design is the balance between targeting efficiency and cytotoxicity.

[0415] Micelles, in general, are spherical synthetic lipid structures that are formed using single-chain lipids, where the single-chain lipid's hydrophilic head forms an outer layer or membrane and the single-chain lipid's hydrophobic tails form the micelle center. Micelles typically refer to lipid structures only containing a lipid mono-layer. Micelles are described in more detail in Quader et al. (Mol Ther. 2017 Jul. 5; 25 (7): 1501-1513), herein incorporated by reference for all purposes.

[0416] Nucleic-acid vectors, such as expression vectors, exposed directly to serum can have several undesirable consequences, including degradation of the nucleic acid by serum nucleases or off-target stimulation of the immune system by the free nucleic acids. Similarly, viral delivery systems exposed directly to serum can trigger an undesired immune response and/or neutralization of the viral delivery system. Therefore, encapsulation of an engineered nucleic acid and/or viral delivery system can be used to avoid degradation, while also avoiding potential off-target effects. In certain examples, an engineered nucleic acid and/or viral delivery system is fully encapsulated within the delivery vehicle, such as within the aqueous interior of an LNP. Encapsulation of an engineered nucleic acid and/or viral delivery system within an LNP can be carried out by techniques well-known to those skilled in the art, such as microfluidic mixing and droplet generation carried out on a microfluidic droplet generating device. Such devices include, but are not limited to, standard T-junction devices or flow-focusing devices. In an example, the desired lipid formulation, such as MC3 or MC3-like containing compositions, is provided to the droplet generating device in parallel with an engineered nucleic acid or viral delivery system and any other desired agents, such that the delivery vector and desired agents are fully encapsulated within the interior of the MC3 or MC3-like based LNP. In an example, the droplet generating device can control the size range and size distribution of the LNPs produced. For example, the LNP can have a size ranging from 1 to 1000 nanometers in diameter, e.g., 1, 10, 50, 100, 500, or 1000 nanometers. Following droplet generation, the delivery vehicles encapsulating the cargo/payload (e.g., an engineered nucleic acid and/or viral delivery system) can be further treated or engineered to prepare them for administration.

Nanoparticle Delivery

[0417] Nanomaterials can be used to deliver engineered nucleic acids (e.g., a nucleic acid encoding a modified ER-LBD or chimeric protein described herein). Nanomaterial vehicles, importantly, can be made of non-immunogenic materials and generally avoid eliciting immunity to the delivery vector itself. These materials can include, but are not limited to, lipids (as previously described), inorganic nanomaterials, and other polymeric materials. Nanomaterial particles are described in more detail in Riley et al. (Recent Advances in Nanomaterials for Gene Delivery-A Review. Nanomaterials 2017, 7 (5), 94), herein incorporated by reference for all purposes.

Genomic Editing Systems

[0418] Genomic editing systems can be used to engineer a host genome to encode an engineered nucleic acid, such as a nucleic acid encoding a modified ER-LBD of the present disclosure. In general, a genomic editing system refers to any system for integrating an exogenous gene into a host cell's genome. Genomic editing systems include, but are not limited to, a transposon system, a nuclease genomic editing system, and a viral vector-based delivery platform.

[0419] A transposon system can be used to integrate an engineered nucleic acid, such as an engineered nucleic acid of the present disclosure, into a host genome. Transposons generally comprise terminal inverted repeats (TIR) that flank a cargo/payload nucleic acid and a transposase. The transposon system can provide the transposon in cis or in trans with the TIR-flanked cargo. A transposon system can be a retrotransposon system or a DNA transposon system. In general, transposon systems integrate a cargo/payload (e.g., an engineered nucleic acid) randomly into a host genome. Examples of transposon systems include systems using a transposon of the Tc1/mariner transposon superfamily, such as a Sleeping Beauty transposon system, described in more detail in Hudecek et al. (Crit Rev Biochem Mol Biol. 2017 August; 52 (4): 355-380), and U.S. Pat. Nos. 6,489,458, 6,613,752 and 7,985,739, each of which is herein incorporated by reference for all purposes. Another example of a transposon system includes a PiggyBac transposon system, described in more detail in U.S. Pat. Nos. 6,218,185 and 6,962,810, each of which is herein incorporated by reference for all purposes.

[0420] A nuclease genomic editing system can be used to engineer a host genome to encode an engineered nucleic acid, such as an isolated polynucleotide or heterologous construct of the present disclosure. Without wishing to be bound by theory, in general, the nuclease-mediated gene editing systems used to introduce an exogenous gene take advantage of a cell's natural DNA repair mechanisms, particularly homologous recombination (HR) repair pathways. Briefly, following an insult to genomic DNA (typically a double-stranded break), a cell can resolve the insult by using another DNA source that has identical, or substantially identical, sequences at both its 5 and 3 ends as a template during DNA synthesis to repair the lesion. In a natural context, HDR can use the other chromosome present in a cell as a template. In gene editing systems, exogenous polynucleotides are introduced into the cell to be used as a homologous recombination template (HRT or HR template). In general, any additional exogenous sequence not originally found in the chromosome with the lesion that is included between the 5 and 3 complimentary ends within the HRT (e.g., a gene or a portion of a gene) can be incorporated (i.e., integrated) into the given genomic locus during templated HDR. Thus, a typical HR template for a given genomic locus has a nucleotide sequence identical to a first region of an endogenous genomic target locus, a nucleotide sequence identical to a second region of the endogenous genomic target locus, and a nucleotide sequence encoding a cargo/payload nucleic acid (e.g., any of the engineered nucleic acids described herein, such as any of the engineered nucleic acids described herein).

[0421] In some examples, a HR template can be linear. Examples of linear HR templates include, but are not limited to, a linearized plasmid vector, a ssDNA, a synthesized DNA, and a PCR amplified DNA. In particular examples, a HR template can be circular, such as a plasmid. A circular template can include a supercoiled template.

[0422] The identical, or substantially identical, sequences found at the 5 and 3 ends of the HR template, with respect to the exogenous sequence to be introduced, are generally referred to as arms (HR arms). HR arms can be identical to regions of the endogenous genomic target locus (i.e., 100% identical). HR arms in some examples can be substantially identical to regions of the endogenous genomic target locus. While substantially identical HR arms can be used, it can be advantageous for HR arms to be identical as the efficiency of the HDR pathway may be impacted by HR arms having less than 100% identity.

[0423] Each HR arm, i.e., the 5 and 3 HR arms, can be the same size or different sizes. Each HR arm can each be greater than or equal to 50, 100, 200, 300, 400, or 500 bases in length. Although HR arms can, in general, be of any length, practical considerations, such as the impact of HR arm length and overall template size on overall editing efficiency, can also be taken into account. An HR arms can be identical, or substantially identical to, regions of an endogenous genomic target locus immediately adjacent to a cleavage site. Each HR arms can be identical to, or substantially identical to, regions of an endogenous genomic target locus immediately adjacent to a cleavage site. Each HR arms can be identical, or substantially identical to, regions of an endogenous genomic target locus within a certain distance of a cleavage site, such as 1 base-pair, less than or equal to 10 base-pairs, less than or equal to 50 base-pairs, or less than or equal to 100 base-pairs of each other.

[0424] A nuclease genomic editing system can use a variety of nucleases to cut a target genomic locus, including, but not limited to, a Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) family nuclease or derivative thereof, a Transcription activator-like effector nuclease (TALEN) or derivative thereof, a zinc-finger nuclease (ZFN) or derivative thereof, and a homing endonuclease (HE) or derivative thereof.

[0425] A CRISPR-mediated gene editing system can be used to engineer a host genome to encode an engineered nucleic acid, such as an engineered nucleic acid described herein. CRISPR systems are described in more detail in M. Adli (The CRISPR tool kit for genome editing and beyond Nature Communications; volume 9 (2018), Article number: 1911), herein incorporated by reference for all that it teaches. In general, a CRISPR-mediated gene editing system comprises a CRISPR-associated (Cas) nuclease and an RNA(s) that directs cleavage to a particular target sequence. An exemplary CRISPR-mediated gene editing system is the CRISPR/Cas9 systems comprised of a Cas9 nuclease and an RNA(s) that has a CRISPR RNA (crRNA) domain and a trans-activating CRISPR (tracrRNA) domain. The crRNA typically has two RNA domains: a guide RNA sequence (gRNA) that directs specificity through base-pair hybridization to a target sequence (a defined nucleotide sequence), e.g., a genomic sequence; and an RNA domain that hybridizes to a tracrRNA. A tracrRNA can interact with and thereby promote recruitment of a nuclease (e.g., Cas9) to a genomic locus. The crRNA and tracrRNA polynucleotides can be separate polynucleotides. The crRNA and tracrRNA polynucleotides can be a single polynucleotide, also referred to as a single guide RNA (sgRNA). While the Cas9 system is illustrated here, other CRISPR systems can be used, such as the Cpf1 system. Nucleases can include derivatives thereof, such as Cas9 functional mutants, e.g., a Cas9 nickase mutant that in general mediates cleavage of only a single strand of a defined nucleotide sequence as opposed to a complete double-stranded break typically produced by Cas9 enzymes.

[0426] In general, the components of a CRISPR system interact with each other to form a Ribonucleoprotein (RNP) complex to mediate sequence specific cleavage. In some CRISPR systems, each component can be separately produced and used to form the RNP complex. In some CRISPR systems, each component can be separately produced in vitro and contacted (i.e., complexed) with each other in vitro to form the RNP complex. The in vitro produced RNP can then be introduced (i.e., delivered) into a cell's cytosol and/or nucleus, e.g., a T cell's cytosol and/or nucleus. The in vitro produced RNP complexes can be delivered to a cell by a variety of means including, but not limited to, electroporation, lipid-mediated transfection, cell membrane deformation by physical means, lipid nanoparticles (LNP), virus like particles (VLP), and sonication. In a particular example, in vitro produced RNP complexes can be delivered to a cell using a Nucleofactor/Nucleofection electroporation-based delivery system (Lonza). Other electroporation systems include, but are not limited to, MaxCyte electroporation systems, Miltenyi CliniMACS electroporation systems, Neon electroporation systems, and BTX electroporation systems. CRISPR nucleases, e.g., Cas9, can be produced in vitro (i.e., synthesized and purified) using a variety of protein production techniques known to those skilled in the art. CRISPR system RNAs, e.g., an sgRNA, can be produced in vitro (i.e., synthesized and purified) using a variety of RNA production techniques known to those skilled in the art, such as in vitro transcription or chemical synthesis.

[0427] An in vitro produced RNP complex can be complexed at different ratios of nuclease to gRNA. An in vitro produced RNP complex can also be used at different amounts in a CRISPR-mediated editing system. For example, depending on the number of cells desired to be edited, the total RNP amount added can be adjusted, such as a reduction in the amount of RNP complex added when editing a large number of cells in a reaction.

[0428] In some CRISPR systems, each component (e.g., Cas9 and an sgRNA) can be separately encoded by a polynucleotide with each polynucleotide introduced into a cell together or separately. In some CRISPR systems, each component can be encoded by a single polynucleotide (i.e., a multi-promoter or multicistronic vector, see description of exemplary multicistronic systems below) and introduced into a cell. Following expression of each polynucleotide encoded CRISPR component within a cell (e.g., translation of a nuclease and transcription of CRISPR RNAs), an RNP complex can form within the cell and can then direct site-specific cleavage.

[0429] Some RNPs can be engineered to have moieties that promote delivery of the RNP into the nucleus. For example, a Cas9 nuclease can have a nuclear localization signal (NLS) domain such that if a Cas9 RNP complex is delivered into a cell's cytosol or following translation of Cas9 and subsequent RNP formation, the NLS can promote further trafficking of a Cas9 RNP into the nucleus.

[0430] The cells described herein can be engineered using non-viral methods, e.g., the nuclease and/or CRISPR mediated gene editing systems described herein can be delivered to a cell using non-viral methods. The cells described herein can be engineered using viral methods, e.g., the nuclease and/or CRISPR mediated gene editing systems described herein can be delivered to a cell using viral methods such as adenoviral, retroviral, lentiviral, or any of the other viral-based delivery methods described herein.

[0431] In some CRISPR systems, more than one CRISPR composition can be provided such that each separately target the same gene or general genomic locus at more than target nucleotide sequence. For example, two separate CRISPR compositions can be provided to direct cleavage at two different target nucleotide sequences within a certain distance of each other. In some CRISPR systems, more than one CRISPR composition can be provided such that each separately target opposite strands of the same gene or general genomic locus. For example, two separate CRISPR nickase compositions can be provided to direct cleavage at the same gene or general genomic locus at opposite strands.

[0432] In general, the features of a CRISPR-mediated editing system described herein can apply to other nuclease-based genomic editing systems. TALEN is an engineered site-specific nuclease, which is composed of the DNA-binding domain of TALE (transcription activator-like effectors) and the catalytic domain of restriction endonuclease Fokl. By changing the amino acids present in the highly variable residue region of the monomers of the DNA binding domain, different artificial TALENs can be created to target various nucleotides sequences. The DNA binding domain subsequently directs the nuclease to the target sequences and creates a double-stranded break. TALEN-based systems are described in more detail in U.S. Ser. No. 12/965,590; U.S. Pat. Nos. 8,450,471; 8,440,431; 8,440,432; 10,172,880; and U.S. Ser. No. 13/738,381, all of which are incorporated by reference herein in their entirety. ZFN-based editing systems are described in more detail in U.S. Pat. Nos. 6,453,242; 6,534,261; 6,599,692; 6,503,717; 6,689,558; 7,030,215; 6,794,136; 7,067,317; 7,262,054; 7,070,934; 7,361,635; 7,253,273; and U.S. Patent Publication Nos. 2005/0064474; 2007/0218528; 2005/0267061, all incorporated herein by reference in their entireties for all purposes.

Other Engineering Delivery Systems

[0433] Various additional means to introduce engineered nucleic acids (e.g., an isolated polynucleotide encoding a modified ER-LBD or chimeric protein described herein) into a cell or other target recipient entity, such as any of the lipid structures described herein.

[0434] Electroporation can be used to deliver polynucleotides to recipient entities. Electroporation is a method of internalizing a cargo/payload into a target cell or entity's interior compartment through applying an electrical field to transiently permeabilize the outer membrane or shell of the target cell or entity. In general, the method involves placing cells or target entities between two electrodes in a solution containing a cargo of interest (e.g., any of the engineered nucleic acids described herein). The lipid membrane of the cells is then disrupted, i.e., permeabilized, by applying a transient set voltage that allows the cargo to enter the interior of the entity, such as the cytoplasm of the cell. In the example of cells, at least some, if not a majority, of the cells remain viable. Cells and other entities can be electroporated in vitro, in vivo, or ex vivo. Electroporation conditions (e.g., number of cells, concentration of cargo, recovery conditions, voltage, time, capacitance, pulse type, pulse length, volume, cuvette length, electroporation solution composition, etc.) vary depending on several factors including, but not limited to, the type of cell or other recipient entity, the cargo to be delivered, the efficiency of internalization desired, and the viability desired. Optimization of such criteria are within the scope of those skilled in the art. A variety of devices and protocols can be used for electroporation. Examples include, but are not limited to, Neon Transfection System, MaxCyte Flow Electroporation, Lonza Nucleofector systems, and Bio-Rad electroporation systems.

[0435] Other means for introducing engineered nucleic acids (e.g., an isolated polynucleotide encoding a modified ER-LBD or chimeric protein described herein) into a cell or other target recipient entity include, but are not limited to, sonication, gene gun, hydrodynamic injection, and cell membrane deformation by physical means.

[0436] Compositions and methods for delivering engineered mRNAs in vivo, such as naked plasmids or mRNA, are described in detail in Kowalski et al. (Mol Ther. 2019 April 10; 27 (4): 710-728) and Kaczmarek et al. (Genome Med. 2017; 9:60.), each herein incorporated by reference for all purposes.

The actual amount administered, and rate and time-course of administration, will depend on the nature and severity of disease being treated. Prescription of treatment, e.g., decisions on dosage etc., is within the responsibility of general practitioners and other medical doctors, and typically takes account of the disorder to be treated, the condition of the individual patient, the site of delivery, the method of administration and other factors known to practitioners. Examples of the techniques and protocols mentioned above can be found in Remington's Pharmaceutical Sciences, 16th edition, Osol, A. (ed), 1980.

Example 1

ERT2 Mutations Predicted to Modulate Ligand Binding

[0783] In silico modeling was conducted for 4-OHT, endoxifen and estradiol binding to a mutant form of estrogen receptor alpha known as ERT2, to identify mutations predicted to have increased sensitivity to 4-OHT, as compared to an ERT2 of SEQ ID NO: 2.

Materials and Methods

[0784] Available crystal structures of a complex between Estradiol and ER (PDB: 1QKU, resolution 3.2 ) and between 4-OHT and ER (PDB: 3ERT, resolution 1.9 ) were used to generate models of the complexes between Estradiol and ERT2, 4-OHT and ERT2, and Endoxifen and ERT2. The ERT2 sequence differs from ER by three residues (G400V/M543A/L544A). Only residues from 306 to 551 were used in the structural models as the available structures were all resolved with only this region.

[0785] Using standard protocols (Kannan et al. ACS Omega. 2017 Nov. 30; 2 (11): 7881-7891.), MD simulations were carried out for apo ERT2, ERT2Estradiol, ERT24-OHT and ERT2Endoxifen complexes (each simulation was carried out for 100 ns in triplicate each). Both the ERT2 and the bound ligand/drug remained stable during the simulations (using standard measures). The conformations generated during the last half (50 ns) of the simulations (the simulations are deemed to have equilibrated) were used for subsequent analyses.

Results

[0786] A first set of mutations was analyzed in silico for improved 4-OHT binding. Eighteen mutations to residues in the ligand binding pocket were selected based on amino acids present at the homologous position for other estrogen receptor proteins. Of the 18 selected mutations, 17 of the mutants bind tighter than wild type ERT2 by at least 1.8 kcal/mol; only the M517A mutation appears to destabilize the binding of 4-OHT (FIG. 1A). Next, binding energy calculations were carried out to see the effect of the mutation on the binding of estradiol. Compared to 4-OHT (in which all mutations except M517A favor the binding as indicated by negative G values) most mutations (FIG. 1B) had negligible effect on the binding of estradiol (G values for all the mutations are within 2 kcal/mol, as compared to the G values of 4-OHT which is >2 kcal/mol for most of the mutations). Only mutations L409V, M517A and N407D exhibited increased binding to estradiol of greater than 1 kcal/mol, but both L409V and N407D bind tighter to 4-OHT by 3 and 4 kcal/mol respectively. The first set of mutations is shown below in Table 6.

[0787] A second set of mutations was analyzed in silico for improved 4-OHT binding. Molecular docking simulations were conducted for 4-OHT and estradiol binding to ERT2, for nineteen different mutations at five additional sites at the ligand binding pocket (in addition to those shown in Table 6), to identify further mutants with increased sensitivity to 4-OHT, as compared to wild-type ERT2. Binding energy calculations were carried out consistent with the calculations performed for the first set of mutations. All nineteen of the mutations exhibited improved binding to 4-OHT in the range of 1.8 kcal/mol to 7 kcal/mol (see FIG. 2). The second set of mutations is shown in Table 7.

[0788] A third set of mutations was analyzed in silico for improved 4-OHT binding. A total of 23 mutations at an additional six residue positions in the ligand binding pocket (residues 428, 346, 349, 418, 421, and 424) were chosen for molecular docking simulations. Binding energy calculations were carried out consistent with the calculations performed for the first set of mutations. Six of the mutations (L346F, L349M, V418I, V418M, 1424M, and M421L) exhibited improved binding to 4-OHT by at least about 1.5 kcal/mol (FIG. 3). These 23 mutations are shown in Table 8.

[0789] A fourth set of mutations was analyzed in silico for improved 4-OHT binding. A total of 23 mutations at an additional six residue positions in the ligand binding pocket (residues 528, 343, 388, 522, 414, and 521) were chosen for molecular docking simulations. Binding energy calculations were carried out consistent with the calculations performed for the first set of mutations. 18 of the 23 mutations exhibited improved binding to 4-OHT by at least about 1.0 kcal/mol (FIG. 4). The fourth set of mutations is shown in Table 9.

[0790] A fifth set of mutations was analyzed in silico for improved 4-OHT binding. A total of 38 mutations at five additional residue positions (residues 524, 525, 347, 350, and 351) were chosen for molecular docking simulations. Binding energy calculations were carried out consistent with the calculations performed for the first set of mutations. 28 of the 38 mutations exhibited improved binding to 4-OHT by at least about 1.0 kcal/mol and up to about 4.5 kcal/mol (FIG. 5). The fifth set of mutations is shown in Table 10.

[0791] All of the mutations for sets 1-5 were further analyzed with molecular docking simulations for binding to endoxifen and estradiol to determine the energy of binding to endoxifen and estradiol (calculated as G in kcal/mol). Additionally, the difference between the binding energy of endoxifen binding as compared to estradiol binding was calculated as G values. A summary of the binding energies for each of 4-OHT, endoxifen, and estradiol, and of the binding energy differences of 4-OHT and endoxifen as compared to estradiol binding is shown in Table 11.

[0792] A sixth set of mutations was analyzed in silico to identify mutants that destabilize the agonist-bound confirmation (i.e., the estradiol-bound conformation) and/or stabilize the antagonist-bound confirmation (i.e., the 4-OHT or endoxifen-bound conformation). A major structural difference between the agonist-bound and antagonist-bound conformations lies in the orientation and docking site of helix 12 (H12, see FIG. 6). A total of 14 mutations at eight residue positions in helix 12 (residues 538, 536, 539, 540, 547, 534, 533, and 537) were chosen for analysis. The difference in free energy of the mutant ERT2 and the wild-type ERT2 in the antagonist-bound conformation, and the difference in free energy of the mutant ERT2 and wild-type ERT2 in the agonist-bound conformation were calculated as AG values. Next, AAG values were calculated, with a negative value indicating that the antagonist-bound conformation of the ERT2 mutant is favored over the agonist-bound conformation of the mutant, and a positive value indicating that the agonist conformation is favored over the antagonist-bound conformation. Seven of the fourteen mutations (D538K, L536F, L536Y, L536M, L539R, H547A, and V534R) stabilized the antagonist confirmation (see FIG. 7). The sixth set of mutations is shown in Table 12.

ERT2 Mutants with Increased Drug Sensitivity Identified by Transfection Screen

[0793] ERT2 mutants identified from the in silico analysis of Example 1 were analyzed by transfection assays for responsiveness to 4-OHT. In a first transfection screen using reporter expression as a read out, constructs encoding ERT2 having mutations described in Example 1 were produced in the background of a wild-type ERT2 as shown in SEQ ID NO: 3 (including the G400V/M543A/L544A/V595A quadruple amino acid substitution). Each ERT2 construct included a ZF10-1 domain for DNA binding, a p65 transcriptional activation domain, and the ERT2 mutant including a modified ER-LBD. Each construct was tested for sensitivity to 4-OHT. Each mutant was cloned into an expression construct for transfection in a HEK293T+YBTATA_mCherry reporter cell line. In a second transfection screen, constructs encoding additional ERT2 mutants described in Example 1 were produced and tested for sensitivity to 4-OHT. For the screens, the cells were treated with three different concentrations of 4-OHT (0.025, 0.1, and 0.25 uM) and then assayed for mCherry expression by fluorescence-activated cell sorting (FACS) (FIGS. 8A-8C, FIGS. 9A-9C, and FIGS. 10A-10C).

Materials and Methods

[0794] HEK293T cells were transduced with a lentivirus encoding a synthetic promoter comprised of 4 ZF10-1 binding sites linked to a YBTATA minimal promoter. This synthetic promoter drives expression of mCherry. Cells from this cell line were called reporter cells.

[0795] On day 1, reporter cells were plated at 1.5e5 cells/well in a 24 well plate. On day 2, cells were transfected with ERT mutants. A mix of 0.6 ug DNA, 1.8 uL Fugene, and 30 uL Optimem was made for each well where the DNA encodes ZF10-1 fused to p65 and the ERT2 mutant including a modified ER-LBD. In some screens a plasmid encoding GFP was included as a control to select transfected cells by flow cytometry. On day 3, cells were split at a ratio of 1:20 and seeded in a 96 well plate. Cells were treated with 0, 0.025, 0.1, or 0.25 uM 4-OHT. On day 5, media was removed and cells were trypsinized and then resuspended in FACS buffer plus Sytox Red (fluoresces in APC channel) viability dye. Cells were run on a flow cytometer and gated by FSC/SSC for cells, FSC/Sytox Redfor live cells, FSC/FSC-Width for single cells, and where possible GFP+ for transfected cells (if transfection control was included). The percent of mCherry positive cells at each drug concentration was plotted and compared to wildtype ERT2, and mutants that were more sensitive to 4-OHT were identified.

Results

[0796] As shown in FIGS. 8A-8C, FIGS. 9A-9C, and FIGS. 10A-10C, the transfection screens identified mutants with improved induction of mCherry expression as compared to an ERT2 (SEQ ID NO: 3). In the first transfection screen, improved expression induction was observed for seventeen of the modified ER-LBD containing constructs: L354I (SB03498), L391V (SB03505), Q414E (SB03383), L409V (SB03375), S463P (SB03393), L384M (SB03377), L354I+L384M (SB03511), N413D (SB03381), M517A (SB03379), G344M (SB03372), I386V (SB03373), N407D (SB03380), C417S (SB03371), R352K (SB03384), Y537S (SB03389), M388F (SB03579), and G521A (SB03587), with the greatest improvement of expression induced by the following seven mutants: L354I (SB03498), L391V (SB03505), Q414E (SB03383), L409V (SB03375), and S463P (SB03393), (FIGS. 8A-8C). In the second transfection screen, improved expression induction was observed for ten of the modified ER-LBD containing constructs: 1424L (SB03558), M421L (SB03566), M421F (SB03567), T347E (SB03801), L536M (SB03828), Y537E (SB03839), T347I (SB03802), and T347M (SB03805), V418I (SB03550), and V533W (SB03838), with strong improvement of expression induced by the following six modified ER-LBD containing constructs: 1424L (SB03558), M421L (SB03566), M421F (SB03567), T347E (SB03801), L536M (SB03828), and Y537E (SB03839) (FIGS. 9A-9C). In the third transfection screen (FIGS. 10A-10C), improved expression induction was observed for the modified ER-LBD containing constructs shown in Table 13.

Mutants with Increased Drug Sensitivity Identified by Transduction Screen

[0797] ERT2 mutants were analyzed by three transduction screens for the ability to induce reporter expression in response to 4-OHT. The mutants L354I+L384M (identified in the first transfection screen) was included in all three transduction screens. Lentiviral vectors were cloned encoding the ERT2 mutants that demonstrated improved response to 4-OHT in the transfection screen from Example 2. The reporter cell line as described in Example 2 was transduced with lentiviruses encoding the ERT2 mutants, and the ability of the mutants to induce mCherry expression in response to a variety of 4-OHT concentrations was assessed.

Materials and Methods

[0798] For the transduction screens, on day 1, reporter cells were plated at 2e5 cells/well in a 12 well plate. On day 2, cells were transduced with lentivirus encoding lead ERT mutants from the transfection screen. On days 3 and 4, cells were passaged to maintain <90% confluency on the plate. On day 5, cells were seeded into 96 well plates and treated with 0, 0.001, 0.0025, 0.004, 0.025, 0.05, 0.1, or 0.25 uM 4-OHT. On day 8, media was removed and cells were trypsinized and then resuspended in FACS buffer plus Sytox Red (fluoresces in APC channel) viability dye. Cells were run on a flow cytometer and gated by FSC/SSC for cells, FSC/Sytox Redfor live cells, the percent of mCherry positive cells at each drug concentration was plotted and compared to wildtype ERT2 to find more sensitive mutants (FIG. 11A). The percent of mCherry positive cells at two of the drug concentrations, 0.004 and 0.025 uM 4-OHT, are also shown in a bar graph (FIG. 11B).

Results

[0799] As shown in FIGS. 11A and 11B, the first transduction screen confirmed improved 4-OHT response for several mutants identified as having improved 4-OHT binding in a transfection screen from Example 2. In particular, the mutants L354I, L391V, Q414E, L409V, S463P, L384M, and L354I+L384M all demonstrated an improved 4-OHT response as compared to a wild-type ERT2 (construct 3422, SEQ ID NO: 3). ERT2 mutants demonstrating improved 4-OHT binding in the first transduction screen are shown in Table 14.

[0800] As shown in FIG. 12, the second transduction screen confirmed improved 4-OHT response for mutants identified in a transfection screen from Example 2. In particular, the mutants M517A, and N413D, and L354I+L384M demonstrated an improved 4-OHT response as compared to wild-type ERT2 (construct 3422). Notably, the improved 4-OHT response of the L354I+L384M mutant was confirmed in both the first and the second transduction screens. ERT2 mutants demonstrating improved 4-OHT binding in the second transduction screen are shown in Table 15.

Modified ER-LBD Library Screen for Assessing Sensitivity of ER-LBD Domains to Ligands

Materials and Methods

Modified ER-LBD Combinatorial Library Screen

[0802] HEK293T cells were transduced with SB04401, a combinatorial ERT2 library (FIG. 14A) comprised of 800 unique ER-LBD variants, each of which are a unique combination of the substitutions given in Table 18 along with rationale for their inclusion. To generate a homogenous cell line where each cell had a unique ER-LBD variant per cell, viral integration of transduced HEK293T cells were quantified by copy number assay. A cell line with an average viral integration of <1 copy of the ERT2 mutant library per cell was identified and subjected to puromycin selection. The selected cell line was then transduced with a SB01066 mCherry reporter (FIG. 14B). Transduced cells were then tested for sensitivity to endoxifen and 4-OHT via the mCherry reporter which will express if an ER-LBD variant is sensitive to tested concentrations as low as about 0.1 nM up to about 1 uM. Cells expressing mCherry and therefor responsive to treatment of endoxifen were sorted followed by isolation of genomic DNA from said sorted cells. Variants were identified from the isolated genomic DNA by PCR amplification of the ERT2 coding sequence followed by insertion of the PCR product into pcr4 TOPO vector (Life Technologies). Colonies obtained were then submitted for Sanger Sequencing. Identified mutants were cloned into constructs, e.g., SB06136-SB06153 (ZF10-1_p65_ERT2 mutant with a modified ER-LBD).

Modified ER-LBD Validation in U87MG with mCherry Reporter

[0803] About 16 hours before transduction 100k U87MG: 1066 cells were seeded into 16 wells in 12 well plate format. During transduction, cells in each well were transduced with 100k pg of virus of ERT2 variant constructs. After transduction, cells were split into 50k cells per well in a 24 well plate format, and treated with drug-free media or a range of endoxifen or 4-OHT drug conditions. About two days after treatment of cells with endoxifen or 4-OHT, cells were collected and mCherry reporter expression was quantified by flow cytometry.

Results

[0804] Screening of the modified ER-LBD construct library identified a subset of ERT2 variants that were sensitive to endoxifen at 1 nM. Among this subset, 15 variants (Table 19) were validated in U87MG cells for their ability to activate an mCherry reporter (SB01066; FIG. 14B) at a range of concentrations of 0 pM, 10 pM, 50 pM, 100 pM, and 1 nM of endoxifen (FIG. 15A) and 4-OHT (FIG. 15B). Expression of mCherry was quantified about 24 hours after treatment with endoxifen or 4-OHT. As demonstrated, all 15 variants were sensitive to endoxifen and 4-OHT at concentrations of about 1 nM or less, whereas negative controls U87MG and U87MG: 1066 negative controls showed no sensitivity.

[0805] Select ERT2 variants (Table 20) from the previous screens were further tested for sensitivity to endoxifen and 4-OHT, compared to wild-type ERT2. Tests showed that activation of wild-type ERT2 begins at about 25 nM endoxifen and at about 25 nM 4-OHT, while three ERT2 variants tested activate mCherry expression at 1 nM and 0.1 nM endoxifen and at 1 nM and 0.1 nM 4-OHT (FIG. 16A-16D). Exemplary heat maps show fold activation of mCherry expression of constructs tested at various concentrations, including 2.2 pM estradiol (FIG. 16B). ERT2 is ER-alpha mutated to be insensitive to estradiol, the lead ERT2 variants were confirmed to continue to be insensitive to biologically observed concentrations of estradiol. Fold activation was calculated by gMFI mCherry levels of each test condition divided by gMFI mCherry levels of U87MG cells transduced with the reporter (SB01066).

Modified ER-LBD Validation in U87MG with IL-12 Reporter

[0806] In another experiment, a U87MG cell line with an IL-12 reporter construct (ZF10-1 BS_pMinYBTATA: IL-12) was transduced with modified ER-LBD constructs SB06136, SB06141, SB06146, SB06149, or unmodified ERT2 construct SB03422 at 1 pg/cell of virus.

[0807] Next day transduced cells were split into wells at 100k cells/well and treated with indicated drug concentration of Endoxifen in a volume of 200 uL media. After 48 hours of drug treatment, supernatants were harvested and quantified for IL-12 expression via ELISA using standard techniques.

[0808] As shown in FIG. 16E, constructs with the modified ERT2-LBD also demonstrated improved sensitivity to tamoxifen metabolites compared to WT (empty circle), as assessed by IL-12 secretion. Additional experiments further indicated that the modified ER-LBD constructs comprising the additional amino acid substitutions L384M/L391V/N413D/M421L/S463P/H524L (ERT2_mutant 81) in a transcriptional reporter assay for dimerization activity did not directly alter dimerization of two modified ER-LBDs to 4-OHT, suggesting dimerization itself was comparable to unmodified ERT2 (data not shown), consistent with substitution site selection based on their predicted impact on binding to tamoxifen metabolites.

[0811] Select ERT2 variants (Table 21; FIG. 17A-17B) from the previous screens were further tested for sensitivity to endoxifen and 4-OHT in primary NK cells. Among the variants tested, SB06142 (mutant 77; L354I/L391V/N413D/M421L/S463P/M517A/H524L), SB06136 (mutant 81; L384M/L391V/N413D/M421L/S463P/H524L), and SB06145 (mutant 62; LA09V/N413D/Q414E/M421L/S463P/H524L) were sensitive to both endoxifen and 4-OHT at concentrations of 0.1 nM (FIG. 17A-17B).

[0812] To demonstrate delivery of a therapeutic polypeptide, ERT2/IL-12 vectors were constructed as shown in Table 22, and tested for sensitivity to endoxifen in primary NK cells. Testing of ERT2/IL-12 vectors in NK cells showed that TL10009, with ERT2-L354I/L391V/N413D/S463P/H524L from SB06142 and crIL12 CD16 CS, shows best induction and fold change in IL-12 (FIG. 18A-18B).

Assessment of Modified ER-LBDS in Induced Cell Death Systems

Suicide-Switch Assay

[0813] A 24-well dish was seeded with 25,000 Lent-X HEK293T cells (Takara, Catalog #: 632180). The next day, the cells were transduced with 25,000 pg of virus for constructs SB07351-SB07354: ERT2mut-casp9 constructs tagged with mCherry to track successfully transduced cells in a population. The constructs each take the form ERT2*mut-Casp9-IRES-RFP (SB07351=mut81; SB07352=mut88; SB07353=mut63; SB07354=mut41). The next day, transduced cells were split into a 96-well plate with 5,000 cells in each well and loaded into an incucyte to quantify cell expansion via images every 2 hours detecting mCherry expression. Media was exchanged 24 hours later with new media with indicated concentration of 4-OHT or no drug added. Cells continued to be imaged by the incucyte every 2 hours for 48 hours post exchange of media.

[0814] Cell death was quantified via detection of suicide-switch linked mCherry expression using the following formula:


Killing efficiency=100((mCherry expression in drug treated population)/(mCherry expression in ND population)) [NOTE: mCherry background prevents 100% KE from being calculated; >95% killing efficiency is considered complete killing in this assay]

Suicide-Switch Assay Results

[0815] The modified ER-LBD variants identified above were assessed in a transcriptional reporter assay (see Example 2 and Example 3). However, as illustrated in FIG. 19, the mechanism of an ER-mediated transcriptional activation generally involves nuclear translocation (FIG. 19, top panel). In contrast, ER-mediated suicide-switch induction generally involves dimerization within the cytoplasm (FIG. 19, bottom panel). Accordingly, the improved sensitivity in the transcriptional activation would not generally predict efficacy and sensitivity for ER-mediated suicide-switch induction given the different mechanisms of action. Thus, modified ER-LBD variants identified above were further assessed in suicide-switch system.

[0816] As shown in FIG. 20, suicide-switch constructs with the modified ER-LBD variants achieved potent killing (>95%) in HEK293T cells at 1 M 4-OHT over a period of 48 hours. As shown in FIG. 21, a suicide-switch construct with the modified ER-LBD variant mut81 achieved potent killing (>95%) in HEK293T cells down to 0.01 pM of 4-OHT and robust killing (80%) at 0.001 pM of 4-OHT. Notably, efficient killing occurred at a concentration 400 lower than the Ctrough of 4-OHT in humans taking FDA approved daily dose of Tamoxifen (see Binkhorst et al. [Breast Cancer Research and Treatment volume 152, pages 119-128 (2015)] and Hussaarts et al [Cancers (Basel). 2019 March; 11 (3): 403.]).

Example 7

Further Assessment of Modified ER-LBDS in Induced Cell Death Systems

[0817] Modified ER-LBD variants described herein are assessed as in the 293T suicide-switch killing assay of Example 6. Included in the assessment are ERT2mut-casp9 constructs SB07351-SB07354 constructs described in Example 6. The modified ER-LBD variants are assessed against the unmodified ERT2 across a at a range of endoxifen concentrations, combinations of tamoxifen metabolites, and estradiol. Conditions include 0, 0.0001, 0.001, 0.01, 0.1, 1.0, 10, 100, 1000, 2.5 nM & 0.4 nM Endoxifen or 4-OHT, 0.25 nM and 0.04 nM Endoxifen and 4-OHT, and 2.2 pM Estradiol.

[0818] What is assessed includes: [0819] 1. Minimum concentration of endoxifen that achieves complete killing with the ERT2 mutants and wt ERT2 suicide switches [0820] 2. Killing efficiency of mutant and wt ERT2 suicide switches at pharmacological concentrations of tamoxifen metabolites estimated in the serum (0.25 nM Endoxifen and 0.04 nM 4-OHT) and in organs/tissue/tumor (2.5 nM Endoxifen& 0.4 nM 4-OHT); and [0821] 3. Continued insensitivity to 2.2 pM of estradiol (minimum level of estradiol observed in a cohort of women at the lowest point in their menstrual cycle).

Example 8

Validation of an Exemplary ERT2 Mutant in Inducible Cell Death System in T Cells

[0822] Primary T cells isolated from a donor were thawed and stimulated with Dynabeads for 24 hours. Next, ERT2*mut81-Casp9-IRES-RFP (SB07351, prepared as lentivirus) was transduced into the T cells. Two days post transduction, cell media were replaced with T Cell media containing IL-2 to promote expansion. 1 week post transduction, cells were quantified for transduction efficiency (Safety kill switch transduction was tracked by expression of RFP tag) by flow cytometry and then loaded into incucyte for quantification of killing efficiency.

Killing Assay:

[0823] D0-D1: Expansion of cells in drug free T cell media (with IL-2) [0824] D1-onward: Drug free T cell media (with IL-2) was exchanged with media containing indicated drug conditions (as well as IL-2) [0825] Killing efficiency was calculated by the following formula:


1(RFP expression of cells in drug treated conditions)/(RFP expression of transduced cells in the No Drug condition)

[0826] FIG. 22 shows killing efficiency of the safety kill switch by day 5 of treatment with indicated drug conditions. The engineered kill switch maintained its insensitivity to Estradiol at 2.2 pM (maximum level of estradiol estimated in women). Strong killing efficiency was demonstrated by day 5 at endoxifen concentrations as low at 0.001 pM, and complete killing efficiency (>=95%) was demonstrated by day 5 at 1 pM and higher. Thus, the engineered safety kill switch ERT2*mut81-Casp9 achieved potent induced cell killing in primary T cells at ligand concentrations that would be pharmacologically relevant in a tumor/tissue/organ environment.

[0827] FIG. 23 shows killing efficiency of the safety kill switch over time at the indicated drug conditions. The elapsed hours are from time elapsed from adding drug. As shown, the safety kill switch was insensitive to 2.2 pM Estradiol, and did not induce cell killing in the absence of the small molecule inducer cocktail (exemplified here as 2.5 nM endoxifen and 0.4 nM 4-OHT. Also as shown, complete killing was observed within 48 hours when stimulated with tamoxifen metabolites (2.5 nM Endoxifen & 0.4 nM 4-OHT). As a positive control for complete killing, T cells transduced with a construct expressing RFP were treated with puromycin.

[0828] Taken together, the results show that the engineered safety kill switch ERT2*mut81-Casp9 achieved potent induced cell killing in primary T cells at pharmacologically relevant ligand concentrations in tumor/tissue/organ environment, had minimal to no killing activity in the absence of the non-endogenous ligands, and maintained insensitivity to the endogenous hormone estradiol at 2.2 pM (the highest concentration observed in women at peak hormone cycle; much lower concentrations observed in men).

[0830] Twenty-four hours later, 3k transduced cells were plated into each well of a 96w plate and cultured in 100 L of drug-free growth media (DMEM+10% FBS, 1% p-s, 1% Glutamax). 16 hours after loading the plate in the Incuyte, media was exchanged with fresh drug-free media or with media containing the following drug conditions for an elapsed time course: 0.25 nM endoxifen and 0.04 nM 4-OHT (serum concentrations of tamoxifen metabolites); 2.5 nM endoxifen+0.4 nM 4-OHT (concentration of tamoxifen metabolites in brain), 2.5 nM estradiol (an ultra-high concentration that exceeds physiological relevance), and no drug control.

[0831] Killing efficiency was calculated by taking the average mCherry area quantified by the incucyte in the drug treated sample divided by the mCherry area quantified in the ND conditions of the same transduced population and subtracting that fraction from 1. 95% KE was defined as complete killing by previous studies with this same mCherry reporter being treated with Puromycin, a toxic drug that results in complete killing of HEK293T cells within 48 hours of application.

[0832] FIG. 24 shows time course results for the indicated drug conditions. Results suggest that all four ERT2 mutant safety switches (mut81, mut 88, mut63, and mut41) achieved greater killing efficiency, and at a faster rate as compared to the WT ERT2 safety switch.

[0833] FIG. 25 shows time course results for the indicated drug conditions. Results suggest that the majority of switches maintained insensitivity to 2.5 nM estradiol even with long exposure times. SB07351 showed modest activity at late time points of exposure to the ultra-high estradiol concentration of 2.5 nM.

Evaluation of Exemplary ERT2 Mutant Transcriptional Switch Activity

[0834] FIG. 26A depicts constructs and experimental methods for evaluating exemplary ERT2 mutant transcriptional switches. U87MG cells were transduced with the mCherry reporter construct SB01066, comprising synthetic promoter comprising a 4ZF-10 zinc finger binding site (SEQ ID NO: 59) linked to a minimal promoter operably linked to an mCherry encoding sequence. This generated a U87MG: 1066 reporter cell line used for assessing transcriptional switch activity of ERT2 transcriptional switch constructs.

[0835] 25k U87MG: 1066 reporter transduced line was transduced at a MOI of 1 with various ERT2 transcriptional switch constructs having the following structure: pSFFV: ZF10-1 (zinc finger DNA binding domain, SEQ ID NO: 84)_TCR linker (SEQ ID NO: 86)_p65 (transcriptional activation domain, SEQ ID NO: 64)_QLCVRGSS linker (SEQ ID NO: 88)_ERT2 domain. The ERT2 mutants included a number of amino acid substitutions in addition to the WT ERT2 mutations G400V/M543A/L544A/V595A. See Table 23 below.

[0836] The next day, cells were split into no drug or drug titration conditions to evaluate performance at a range of endoxifen and estradiol concentrations. Performance of each ERT2 mutant transcriptional switch was evaluated by their ability to translocate and bind to the zinc finger binding site upstream of mCherry and initiate mCherry expression.

[0837] FIG. 26B shows log 10 fold activation across a range of endoxifen concentrations, normalized to no virus control. mCherry fold activation was calculated by first normalizing the gMFI mcherry values quantified by the background observed in the NV followed by dividing the normalized gMFI mCherry value in the drug treated condition by its corresponding ND sample. The background normalized ND (0) conditions were divided by the average NV gMFI mCherry value in order to reflect any basal activity seen by each mutant. FIG. 26C depicts induced mCherry expression plotted against basal activity for each of the tested ERT2 transcriptional switch constructs. As indicated in FIGS. 26B and 26C: SB09642, SB09657, SB09626, and SB09652 exhibited the highest fold activation and induced mCherry levels, as compared to WT (SB03422). Lead ERT2 mutants SB09642, SB09652, SB09657, SB09626 also displayed similar (or lower) basal activity to WT ERT2.

[0838] FIG. 27 shows mCherry gMFI after background subtraction across a range of estradiol and endoxifen concentrations. Results indicate that all lead ERT2 mutants maintained insensitivity to estradiol even at the ultra-high concentration of 2.5 nM, while maintaining robust sensitivity at 2.5 and 100 nM endoxifen.

Evaluation of Exemplary ERT2 Mutant Transcriptional Switch Activity for Inducing Expression of an IL-12 Payload

[0839] FIG. 28A depicts constructs and experimental methods for evaluating exemplary ERT2 mutant transcriptional switches for inducing expression of an IL-12 payload. U87MG cells were transduced with construct SB02357, comprising synthetic promoter comprising a 4ZF-10 zinc finger binding site (SEQ ID NO: 59) linked to a minimal promoter operably linked to an IL-12 encoding sequence. This generated a U87MG: 2357 reporter cell line used for assessing the ability of ERT2 transcriptional switch constructs to activate transcription of the IL-12 payload in a ligand-dependent manner.

[0840] 25k U87MG: 2357 IL-12 payload transduced line was transduced with MOI of 1 of the ERT2 constructs SB03422, SB06149, SB09626, SB09642, SB09652, and SB09657, which are described in Example 9. These were a subset of the ERT2 mutant transcriptional switch constructs that showed particular promise from the mCherry reporter experiment in Example 9. The next day, cells were split into ND or drug titration conditions to evaluate performance at a range of Endoxifen and concentrations. 72 hours later, supernatant was harvested for quantification of IL-12 by IL-12p70 ELISA. IL-12 levels were read with a spectrophotometer at wavelength 450 nm with wavelength correction to 540 nm according to manufacturer's protocol. A kit-provided standard to calculate detected levels of IL-12 in 100 L of media harvested from 100k cells based on OD. Displayed values were scaled to reflect IL-12 levels as pg/mL produced by 1 million cells.

[0841] Results are shown in FIGS. 28B and 28C. FIG. 28B shows that the tested ERT2 mutant constructs SB06149, SB09626, SB09642, SB09652, and SB09657 induced IL-12 expression at concentrations as low as 0.1 nM endoxifen. FIG. 28C shows IL-12 levels of induced IL-12 levels plotted against basal IL-12 levels at 2.5 nM endoxifen. All tested mutants transcriptional switch constructs exhibited similar basal activity as the WT ERT2 transcriptional switch construct, and further exhibited much higher IL-12 induction at the 2.5 nM endoxifen concentration as compared to WT ERT2.

Evaluation of Additional ERT2 Mutant Safety Switch Constructs

[0842] FIG. 29A shows an experimental workflow for evaluating suicide switch activity for a number of additional ERT2 mutant safety switch constructs.

[0843] A 24-well dish was seeded with 25,000 Lent-X HEK293T cells (Takara, Catalog #: 632180). The next day, the cells were transduced with 25,000 pg of virus for constructs SB12594-SB12607: ERT2mut-casp9 constructs tagged with RFP to track successfully transduced cells in a population. The constructs each take the form ERT2*mut-Casp9-IRES-RFP. See Table 24.

[0844] The next day, transduced cells were split into a 96-well plate with 3,000 cells in each well and loaded into an incucyte to quantify cell expansion via images every 2 hours detecting mCherry expression. Media was exchanged 24 hours later with new media with indicated concentration of 4-OHT or no drug added. Cells continued to be imaged by the incucyte every 4-8 hours for 72-140 hours post exchange of media.

[0845] >95% killing efficiency is considered complete killing in the assay by treatment of mCherry expressing cells with 2 uM Puromycin which is known to kill HEK293T cells within 48 hours of application. 2.5 nM Endoxifen and 0.4 nM 4-OHT reflect the estimated concentrations of tamoxifen metabolites in the brain, tissue, organs, and solid tumors. 0.25 nM endoxifen and 0.04 nM 4-OHT reflect the estimated concentration of tamoxifen metabolites in the serum. Both estimates are based on clinical data measuring tamoxifen metabolite concentrations in the serum of people taking the FDA-approved dose of tamoxifen orally (20 mg/day). It has been observed in vivo that tamoxifen 10 concentrates in tissues, organs, solid tumor, brain.

[0846] Results are shown in FIG. 29B. ERT2 mutants in constructs SB12594, SB12596, achieved complete killing within 48 hours of induction with brain (solid square) and serum (solid triangle) concentrations of tamoxifen metabolites. SB12598, SB12599, SB12600, and SB12601 switches achieved complete killing at brain concentration of tamoxifen metabolites, but not serum concentrations. SB12595 achieved and maintained 90% killing efficiency within 48 hours at both brain and serum concentrations of tamoxifen metabolites. Furthermore, the engineered ERT2 mutants in constructs SB12594-12596 and SB12598-12601 remained insensitive to physiological concentrations of estradiol.
