[0138] 3. Dual-function vectors targeting one or more immune checkpoints Tumor cells express various immune checkpoints, e.g., checkpoint ligands. Therefore, even if one immune checkpoint is inhibited, other immune checkpoints may not be inhibited. It may be difficult to expect sustained effects of CAR-T through point activation. It primarily uses a combination of monoclonal antibodies to inhibit multiple immune checkpoints. Its antitumor effects have been continuously reported (J Clin. Invest., 2019). 015.,Chauvin,JM;PNAS,2010,Curran MA;Bloo d,2018,Wierz,M;Cancer cell.2014,Johnston However, it is known that therapeutic antibodies can induce excessive immune responses throughout the body.

[0140] Vectors include DNA, RNA, plasmids, lentiviral vectors, and adenovirus. The vector may be selected from among vectors and retroviral vectors, e.g., lentiviruses. Viral and retroviral vectors are used to insert genes into the genomic DNA of cells and transmit the genes. In some embodiments, for example, two-in-one functions are achieved by Using a lentiviral vector, for example, a dual vector with two functions in one, The gene on the vector can be inserted into the genome of the cell.

[0142] In some embodiments, the expression of two shRNAs is controlled by two different promoters. In some embodiments, two The promoter is a promoter for RNA polymerase III. In this example, the two promoters are U6 promoters from different species. In an embodiment, the two promoters are oriented in different directions from each other on the vector. For example, in certain embodiments, the promoters are oriented in a head-to-head manner. In embodiments, the promoter is oriented in an end-to-end direction. , genes that weaken immune cell function are receptors or ligands of immune checkpoints .

In some embodiments, the two shRNAs target different parts of PD-1. In some embodiments, the two shRNAs are PD-1 and TIM-3, respectively. In some embodiments, the base sequences encoding the two shRNAs are: It comprises different sequences selected from the group consisting of SEQ ID NOs: 2-219.

[0145] In some embodiments, the target of the CAR or TCR, e.g., mTCR, is a Among the cancer antigens that are increased in the tumors, or mutated forms of cancer antigens found in the tumors The human tumor antigen is selected from the following:

[0146] In some embodiments, the vector comprises either the nucleic acid sequence of SEQ ID NO: 220 or 221. In some embodiments, the vector may be DNA, RNA, a plasmid, or Among lentiviral vectors, adenoviral vectors, and retroviral vectors be selected.

[0147] 3.1 RNA interference and short hairpin RNA RNAi (post-transcriptional gene silencing (PTGS), quelling, or co-suppression) (also known as mitochondrial DNA fragments) occur when an RNA molecule typically causes the destruction of a specific mRNA molecule. It is the process of post-transcriptional gene silencing that inhibits gene expression in a sequence-specific manner. The active component of RNAi is a short double-stranded RNA called small interfering RNA (siRNA). NA (dsRNA), which is usually 15-30 nucleotides (e.g., 19-25 , 19-24 or 19-21 nucleotides) and a dinucleotide 3' overhang These short RNA species contain the same sequence as the target gene and match the nucleic acid sequence of the target gene. It may be naturally generated in vivo by Dicer-mediated cleavage of dsRNA, These are functional in mammalian cells. DNA expression plasmids can be used to express the vectors described herein. The siRNA duplex or dsRNA containing the nucleotides is stably expressed in cells to inhibit target gene expression. Long-term inhibition can be achieved. In one embodiment, the sense and antisense strands of the siRNA duplex The sense strand usually induces the expression of a stem-loop structure called short hairpin RNA (shRNA). The hairpins are connected by a short spacer sequence that provides the hairpin recognition and It is cleaved to generate the mature siRNA molecule.

[0148] Short hairpin RNA (shRNA), as used herein, refers to any RNA having some self-complementarity. The sequence of the RNA molecule creates a tight hairpin structure with its stem. The shRNA molecules are typically about 40-120 nucleotides in length, e.g., about 70-90 nucleotides. In an exemplary embodiment, the shRNA may be 80 nucleotides in length. shRNAs can be of any length. They are designed to activate microinteracting proteins that are endogenous triggers of the RNAi pathway. miRNAs (Lu et al., 2005, Advances in nces in Genetics,54:117-142,Fewell et al. .,2006,Drug Discovery Today,11:975-982). Once an shRNA is expressed in a cell, it is processed through a series of steps to silence the gene. The resulting small interfering RNA (siRNA) acts as a guide for the transcription of the target gene. Once expressed, the hRNA is processed by the Drosha complex within the cell to form pre-shRNAs. A, which is then transported out of the nucleus, where it is further processed by Dicer to form siRNP A, then single-stranded, and then negatively reacted with RISC (RNA-induced silencing complex). Here, the antisense strand of the siRNA is transported by the RISC complex to the mRNA of the target gene. This acts as a guide for the attachment of NA to the RISC complex, and the RISC complex attached in this way is Cleavage of RNA results in gene silencing. This allows for sustained and specific gene silencing of a specific gene, making it possible to It is included in the vector for the purpose of inhibition.

[0149] Naturally expressed small RNAs called microRNAs (miRNAs) are the building blocks of mRNA. RISC-containing m The iRNA is composed of nucleotides 2–7 of the 5′ region of the miRNA, called the seed region. miRNs target mRNAs that display sequence complementarity and other base pairs in their 3' region. A-mediated downregulation of gene expression is mediated by target mRNA cleavage, translational inhibition of target mRNA, and or mRNA decay. The sequences targeted by miRNAs are usually , located in the 3'-UTR of target mRNAs. A single miRNA originates from various genes. Over 100 transcripts may be targeted, and one mRNA may be targeted by many different miRNAs. It may also be a target.

[0150] siRNA duplexes, or dsRNA, that target specific mRNAs are engineered in vitro. Elb may be synthesized and introduced into cells to activate the RNAi process. Ashir et al. developed a 21-nucleotide siRNA duplex (called a small interfering RNA) However, it has been shown to induce potent and specific gene knockdown in mammalian cells without inducing an immune response. It has been demonstrated that this can be achieved (Elbashir, SM et al., Nat Since this first report, siRNA-mediated Post-transcriptional gene silencing is a powerful tool for genetic analysis in mammalian cells. It is quickly emerging as a promising new treatment option.

[0151] For example, polyglutamines that cause polyglutamine expansion diseases such as Huntington's disease RNAi molecules designed to target nucleic acid sequences encoding repeat proteins have been US Patent Nos. 9,169,483 and 9,181,544, and International Patent Publication WO2 015179525, the contents of each of which are incorporated by reference in their entirety.

No. 6,229,999, the contents of each of which are incorporated herein by reference in their entirety.

[0152] siRNA molecules synthesized in vitro are introduced into cells to activate RNAi. The exogenous siRNA duplex may be expressed in the same manner as endogenous dsRNA when it is introduced into a cell. Once assembled, they form a complex that is complementary to one of the two strands of the siRNA duplex (all of which are complementary to one of the two strands of the siRNA duplex). RNA-guided subunits, which are assembly complexes that interact with RNA sequences (i.e., antisense strands), During this process, the siRNA can form a ribosomal isoform (RISC). The sense strand (or passenger strand) is lost from the complex, while the anti- The sense strand (or guide strand) corresponds to its complementary RNA. The ISC complex targets mRNAs that display perfect sequence complementarity. -mediated gene silencing occurs by cleaving, releasing, and degrading the target do.

[0153] Consists of a sense strand that is homologous to the target mRNA and an antisense strand that is complementary to the target mRNA The siRNA duplex may be a single-stranded (ss)-siRNA (e.g., an antisense strand RNA or in terms of the efficiency of target RNA destruction compared to the use of antisense oligonucleotides offer a much greater advantage than the corresponding duplex, which often provides more effective gene silencing. To achieve the desired efficacy, even higher concentrations of ss-siRNA are required.

[0154] Guidelines for designing siRNAs exist in the art. The primer generally consists of a 19-nucleotide sequence that targets the region of the gene to be silenced. a double-stranded region, a symmetric 2-3 nucleotide 3' overhang, a 5'-phosphate group and a 3 It is recommended to generate a '-hydroxyl group. The preference of the siRNA sequence may be controlled. Other rules include: (i) A / U at the 5' end of the antisense strand; (ii) A / U at the 5' end of the sense strand; (iii) at least five A's in the 5'-end one-third of the antisense strand; / U residues; (iv) absence of GC stretches greater than 9 nucleotides in length, In accordance with such considerations, the mammalian genome may be expressed in combination with the specific sequence of the target gene. Highly effective siRNA molecules essential for silencing target gene expression in animals are readily available. It may be designed.

[0155] As provided herein, dual-function vectors can be used to inhibit immune cell function. one or more types of short hairpin RNA (shRNA) that inhibit the expression of one or more genes that attenuate ) and a chimeric antigen receptor (CAR) or T cell receptor (TCR) For example, a nucleotide sequence encoding any one of the monoclonal T cell receptors (mTCR) Columns and

[0156] In some embodiments, the nucleic acid sequence inhibits the expression of a gene that attenuates immune cell function. In some embodiments, the base sequence encodes a single shRNA that is expressed in an immune cell. The gene encodes two types of shRNA that inhibit the expression of two genes that weaken their functions. In another embodiment, the vector is referred to as a "two-in-one dual vector." The sequence inhibits the expression of more than two genes that weaken immune cell function. Encodes hRNA.

[0157] In some embodiments, two or more types of shRNAs are used to identify immune cell functions. Attenuating a single gene, e.g., by targeting different parts of a single gene For example, two or more types of shRNAs may be used to target various PD-1 receptors, e.g., PD-1. In other embodiments, two or more shRNAs can target different regions. , which target different genes that weaken immune cell function, e.g., PD-1 and T It may be characterized by targeting IM-3.

[0158] In an exemplary embodiment, the base sequences encoding two or more types of shRNAs are are various sequences selected from the group consisting of SEQ ID NOs: 2 to 219 and 238 to 267 For example, they may be selected from the group consisting of SEQ ID NOs: 2 to 117 and 238 to 267. For example, they may comprise different sequences selected from SEQ ID NOs: 2 to 12, 7 and may include various sequences selected from the group consisting of 0 to 75 and 266 to 267. It may be characterized as being good.

[0159] In some embodiments, the expression of two shRNAs is controlled by two different promoters. Each gene is regulated by a different gene, minimizing the chance of recombination or deletion during cloning. The method may be characterized by keeping the number of times of the noise to a minimum.

[0160] In some embodiments, the RNA polymerase binds to the promoter and initiates transcription. Depending on which promoter initiates the transcription, the promoter can be an RNA polymerase I promoter, an RNA polymerase II promoter, or an RNA polymerase III promoter. The promoter may be a promoter for RNA polymerase II or a promoter for RNA polymerase III. The above two promoters are RNA polymerase III promoters (hereafter referred to as The promoter may be a Pol III promoter. The motor can translocate without a 5'-end cap or under promoter control. from the 5' end to the 3' end without adding a poly(A) tail to the 3' end of the transcribed RNA Pol III promoters can be engineered to transcribe precisely at the 6 promoter, H1 promoter, 7SK promoter, etc., but are not limited to these. The two promoters contained in the vector may be different, and the above three types and the same type of promoter may be selected from Pol III promoters including If two promoters are selected, they may be from different species. For example, is a U6 promoter, such as the U6 promoter from human and mouse, It may be a U6 promoter from a different species. The shRNA is then transported to the Drosha complex, which is present in the nucleus, where it is then transported to the nucleus. It is believed that this can promote the process of pre-shRNA processing. .

[0161] In some embodiments, two or more promoters are oriented in different directions relative to one another on the vector. For example, in certain embodiments, the promoter may be In another embodiment, the promoter is oriented in a two-headed (→←) direction. It is directed towards the end (←→). In a dual vector with two functions, the vector The fact that they are directed in different directions on the chromosome means that their expression is regulated by two promoters. When each shRNA is transcribed, the RNA polymerase moves in a single direction. In an exemplary embodiment, two promoters are oriented in different directions in a nucleic acid molecule. In another exemplary embodiment, the motor can be in the →← direction (FIG. 15A). The promoters can be in a ←→ orientation (Figure 15B). For example, two promoters can be assumed to be in the →← direction of the vector.

[0162] In some embodiments, the expression of the target gene(s) of one or more shRNAs is compared with that of a control group. The expression of the target gene is reduced to about 90% or less of that of the control group, for example, the expression of the target gene is reduced to about 80% of that of the control group. Below, 70% or less, about 60% or less, about 50% or less, about 40% or less, about 30% or less, about 20 % or less, and about 10% or less.

[0163] Usually, shRNAs contain a sequence highly homologous to a part of the mRNA sequence of the target gene (hereafter referred to as the "seq"). The sequences were selected based on the base sequence of the shRNA, sequences that can generate sharp hairpins, and sequences with high homology. It is designed to have a complementary sequence (hereafter referred to as the antisense shRNA base sequence). The non-covalent bond between the self-complementary portions forms a stem structure, allowing the shRNA to be expressed in cells and When processed, the antisense shRNA sequence mediates the gene silencing process. For example, shR acts as a guide for mRNA of a target gene in the target gene. The nucleotide sequence of the cassette used for expression of NA is NNNNNNNNNNNNNNNNNN NNN (21 bases) - loop sequence -NNNNNNNNNNNNNNNNNNNNNN (19 bases) In one embodiment, the 21-base stretch can include a sense shRNA salt structure. The 19 base stretch encodes a base sequence, and the 19 base stretch is complementary or substantially complementary to the 21 base stretch. In another embodiment, a 19-base segment encodes an antisense shRNA sequence. The 21-nt section encodes the sense shRNA sequence, and the 21-nt section is complementary to the 19-nt section. is substantially complementary to and encodes an antisense shRNA sequence. Upon expression, the resulting RNA forms a stem and loop structure. Such sense or antisense sequences of the target gene (of human origin) may be included in the cassette. The shRNA base sequence is selected from the group consisting of SEQ ID NOs: 1 to 219. In an embodiment, the base sequence of the cassette used to express the shRNA herein is SEQ ID NO:2 It can be selected from the group consisting of 20 to 224.

[0164] In some embodiments, the complete shRNA sequence is expressed as a mouse or human U6 promoter. can be placed at the 3' end of the promoter to terminate transcription by the U6 promoter. The required TTTTT can be placed at the 3' end of any shRNA sequence.

[0165] In some embodiments, the nucleic acid sequence of each shRNA is in addition to the sequences described herein. In addition, at least 50%, particularly at least 70%, and more particularly is at least 80%, even more specifically at least 90%, and most specifically at least The nucleic acid sequence may contain a nucleic acid sequence that exhibits at least 95% sequence homology. In the case of small interfering RNAs (shRNAs) and shRNAs that are processed intracellularly to become siRNAs, Mutations, especially those at the 5' end, are tolerated and result in successful knockdown of the target gene. and have a structure similar to miRNA, which plays a role in gene silencing. Mutations in siRNA and shRNA induce more effective target gene knockdown Furthermore, it is obvious to those skilled in the art that the use of vectors The reason is that variations within the vector, i.e., the clones used to introduce specific sequences into the vector, additions, modifications or deletions of base sequences that may occur during the scanning process, or The construction of components to improve the ease of use of vectors to express the intended gene. It is a change or introduction.

[0166] There are various mechanisms of action for genes that weaken immune cell function. inhibiting proliferation or causing cell death, and activating immune cell responses This reduces the reaction with molecules that are necessary for immune cells to recognize their target. Instead of inhibiting the expression of essential genes and triggering an immune response against specific targets, These cells induce differentiation into different types of immune cells with different functions. Typical examples include molecules related to immune checkpoints, as described below. Not limited to these.

[0167] In some embodiments, the gene that attenuates immune cell function is one that inhibits immune checkpoint activity. The immune checkpoint may be characterized as a receptor or ligand for a specific immune checkpoint. These are molecules present in the immune system that can turn the immune response on or off. Viewed as a fail-safe mechanism that regulates excessive activation of immune cells that can lead to cell death and autoimmune reactions These immune checkpoint molecules act as stimulatory immune checkpoints that enhance immune responses. These are broadly divided into inhibitory immune checkpoint molecules and inhibitory immune checkpoint molecules that inhibit immune responses. Many cancer cells express inhibitory immune checkpoint signals, especially immune By activating the receptors and ligands of inhibitory immune checkpoints on immune cells, It has been reported that these cells can evade the immune system, and therefore are suitable for immune cell therapy targeting specific cancers. The method may be effective by countering this evasive action of cancer, which is called suppression. By inhibiting the activation of regulatory immune checkpoint receptors and their ligands This may be achieved by increasing or decreasing their expression. The receptors and ligands of the checkpoints are PD1 (programmed cell death protein 1), PD- L1 (programmed death ligand 1), CTLA4 (cytotoxic T lymphocyte-associated protein 4) ), TIM-3 (T-cell immunoglobulin and mucin domain-containing-3), CEACAM ( Cancers containing the three subtypes CEACAM-1, CEACAM-3, or CEACAM-5 fetal antigen-related cell adhesion molecule), LAG3 (lymphocyte activation gene 3), VISTA (T V domain Ig suppressor of cell activation), BTLA (B and T lymphocyte attenuating factor), TIGIT (T cell immunoreceptor with Ig and ITIM domains), LAIR1 (leukemia leukocyte-associated immunoglobulin-like receptor 1), CD160 (cluster of differentiation 160), CD96 ( antigen group 96), MerTK (proto-oncogene tyrosine protein kinase MER), and 2B 4 (NK cell activation-inducing ligand), for example, PD1, A choice may be made between TIM3 and TIGIT.

[0168] In another embodiment, the gene that attenuates immune cell function is one that is expressed by a gene that attenuates immune cell function upon repeated stimulation by a TCR. Thus, negative regulatory factors for activated T lymphocytes, such as FAS (CD95, AICD (activating apoptosis antigen-1) acts as apoptosis inhibitor. The cell death inhibitor may be characterized by encoding a receptor capable of promoting mitochondrial cell death (mitochondrial cell death). In some embodiments, the gene that attenuates immune cell function is one that inhibits TCR signal activation. For example, the factor may encode a factor that inhibits CD45, PP2 A, SHP1, SHP2, DGK alpha, DGK zeta, Cbl-b, Cbl-c and In some embodiments, the inhibitors of the present invention can be selected from the group consisting of CD148, CD150, CD160, CD200, CD300, CD400, CD500, CD600, CD800, CD90, CD101, CD112, CD113, CD114, CD120, CD135, CD148, CD151, CD152, CD153, CD154, CD155 The gene that inhibits 4-1BB signaling is thought to be involved in CAR and / or TCR, e.g. For example, the gene may be characterized by encoding a protein that suppresses the efficacy of mTCR. The BB binds to a costimulatory molecule described herein, such as LRR1 (Leucine-Rich In some embodiments, the gene that attenuates immune cell function is a repeat protein 1). , whose ligands are cytokines and receptors that inhibit T cells, such as TGFBR1 ( Transforming growth factor beta receptor 1) and IL10R alpha (IL-10R subunit In some embodiments, the immune cells may be characterized by encoding a nucleotide sequence encoding a nucleotide sequence (nucleotide sequence alpha). The gene whose function is attenuated inhibits the proliferation and cytotoxicity of T cells and NK cells. Characterized by encoding a receptor, such as KLGR1 (killer cell lectin-like receptor G1) In some embodiments, the gene that attenuates immune cell function may be knocked out. A novel DNA methyltransferase that has been reported to suppress T cell exhaustion when knocked out Regulatory factors related to transcription, such as TNMT3a (DNA methyltransferase 3a) In some embodiments, the function of the immune cell is enhanced by encoding a gene encoding a target gene. When activated, genes that attenuate this inhibit the cytotoxic and cytokine-producing capacity of T cells. Adenosine receptors, such as A2aR (Adenosine receptors), are present in excess in the tumor microenvironment. It may be characterized by encoding adenosine receptor subtype A2a).

[0169] In some embodiments, the gene that attenuates immune cell function is selected from the group consisting of FAS, CD4 5, PP2A, SHP1, SHP2, DGK alpha, DGK zeta, Cbl-b, Cb lc, CD148, LRR1, TGFBR1, IL10RA, KLGR1, DNMT3 A and A2aR.

[0170] 3.2 Chimeric Antigen Receptors (CARs) and T Cell Receptors, e.g., Monoclonal T Cells Receptor (mTCR) As provided herein, dual-function vectors can be used to inhibit immune cell function. one or more types of short hairpin RNA (shRNA) that inhibit the expression of one or more genes that attenuate ) and a chimeric antigen receptor (CAR) or T cell receptor (TCR) For example, a nucleotide sequence encoding any one of the monoclonal T cell receptors (mTCR) Columns and

[0171] CARs generally, when present on immune cells, direct the immune cells to target cells (usually cancer cells). While having specificity for the target, it is also a polypeptide that causes signal transduction within the cell. At a minimum, a CAR is a set of extracellular antigens that recognize the target antigens listed below. It contains a recognition domain, a transmembrane domain, and an intracellular signaling domain, and The null transduction domain is derived from a stimulatory or costimulatory molecule.

[0172] The CAR structure commonly used in clinical applications today is a single-chain antibody that confers specificity to an antigen. The fragment variable domain (hereinafter referred to as scFv) and the spacer that controls the distance between the scFv and the cell membrane. The third domain, the transmembrane domain, and the intracellular signaling domain (hereafter referred to as ISD) The ISD then contains one or more costimulatory domains that contribute to the in vivo proliferation and longevity of T cells. (CD28, CD137, or OX40) and TCR signaling that contributes to T cell activation The CA prepared in this manner contains a transduction domain (CD3 zeta, CD3ζ). T cells engineered to express R can target cancer cells expressing the target antigen with high specificity. and activates the IL-1 receptor by recognizing it, effectively inducing the death of such cancer cells, while They can grow exponentially in the body and survive for a long time. For example, B cell-specific CAR-T cells (CART-19) engineered to target the antigen CD19 When administered to patients with B-cell leukemia, the cells multiplied 1,000 to 10,000 times, As a result, CART-19 has been shown to be effective against conventional chemotherapy and other cancers. This study was conducted on patients with terminal acute lymphoblastic leukemia (B-ALL) for whom other treatments were ineffective. Clinical trials showed a 90% complete response rate, and investigator-initiated early clinical trials This led to a rare case of licensing to a global pharmaceutical company in 2017. It became the first CAR-T cell therapy approved by the US FDA, but it was later approved by the second AR-T was also approved.

[0173] Immune cells, such as T cells, have CTLA-4 (cytotoxic T lymphocyte-associated protein 4) on their surface. immune checkpoints such as protein 4 (PD-1) or PD-1 (programmed cell death protein 1) These receptors primarily prevent excessive T cell activation and cell death, as well as However, cancer cells, especially Solid tumors have been reported to use this to evade immune surveillance by T cells. For example, When cancer cells express PD-L1 (programmed death ligand 1) on their surface, the receptor T cells expressing PD-1 recognize cancer cells and are activated, but the activation from PD-1 These immune checkpoint receptors are quickly exhausted by inhibitory signals. To prevent these signals from inhibiting T cell activity, the immune checkpoint receptors are targeted. Monoclonal antibodies against CTLA4 or PD-1, etc., that inhibit signal transduction by By using these immune checkpoint receptor inhibitors, Therapies that improve overall immune function of T cells through immune checkpoint blockade are It has also shown efficacy against a variety of solid cancers.

[0174] CAR-T cells are also a treatment that ultimately depends on the cytotoxicity of activated T cells. The presence of an immunosuppressive environment around CAR-T cells is a major obstacle to therapeutic efficacy. In fact, unlike the therapeutic effects shown in B-cell leukemia, targeting solid tumors CAR-T cells engineered in this way have rarely shown promising therapeutic effects. This is because, unlike blood cancers, solid tumors create an immunosuppressive tumor microenvironment that can inhibit CAR- It is thought that this is because it suppresses the activity and proliferation of T cells. Even among those with acute lymphoblastic leukemia, nearly 90% responded to treatment with CART-19. Unlike patients with hematologic malignancies (ALL), treatment efficacy is similar to that of patients with lymphoma (20-50% response rate) or The response rate was relatively low in patients with chronic lymphoblastic leukemia (CLL, around 20%). It has been reported.

[0175] Furthermore, PD-L1 and other immunosuppressive ligands are involved in the regulation of tumor microenvironment formed by lymphoma. It has been reported that T cells in cancerous tissues are functionally exhausted due to the expression of T cells in the microenvironment. Furthermore, T cells obtained from CLL patients express PD-1, CD160, and CD244 are already substantially exhausted by high expression of immune checkpoint receptors such as It has been reported that:

[0176] To restore this decreased activity of CAR-T cells, CAR-T cells and anti-CTLA- Preclinical results suggest that the simultaneous use of anti-PD-1 inhibitors improves anti-cancer efficacy. Although clinical trials using these combinations have been reported, clinical trials using these combinations are currently underway. The challenge with such simultaneous antibody and CAR-T cell therapy is the ability of antibodies to spread throughout the body. This affects not only CAR-T cells but also all other T cells present in the body, e.g. For example, cytokine release syndrome and severe, systemic adverse reactions such as autoimmune conditions. Another challenge that has been pointed out is the cost of cell therapy and expensive antibodies. The increased cost of treatment resulting from the combination of therapies.

[0177] Therefore, to enable immune checkpoint suppression in CAR-T cells, Recent attempts have been made to regulate gene expression within the cells. 69282 is a group consisting of TCR α chain, TCR β chain, β-2 microglobulin, and FAS. and further comprising a nucleic acid capable of down-regulating endogenous gene expression selected from the group consisting of: Encoding a modified T cell receptor (TCR) that contains affinity for a surface antigen on a target cell. Electroporation of nucleic acids encoding a chimeric antigen receptor (CAR) The publication discloses compositions and methods for generating T cells containing the nucleic acid. Knock out endogenous gene expression using genetic scissors like SPR / Cas9 However, the method for preparing CAR-T cells disclosed in the patent publication is quite complicated. However, they state that there are problems such as low production yield and high production costs.

[0178] On the other hand, International Patent Publication WO2015 / 090230 discloses a compound that further suppresses the function of T cells. A single short hairpin RNA (shRNA) that inhibits the gene expression was used in cells expressing CAR. The cost of cell therapy is high, so if it fails, the patient may be However, a single shRNA can be used to target such molecules. In some embodiments, the activity of the poly In some embodiments, a set comprising a polypeptide may be linked. The set is a form in which they are linked via a switch that dimerizes upon stimulation. In some embodiments, the CAR comprises an extracellular antigen recognition domain and a transmembrane domain. The protein may be a fusion protein comprising an amino acid sequence and an intracellular signaling domain. In embodiments, the CAR fusion protein may further comprise a leader sequence at the N-terminus. The driver sequence is cleaved during the process of CAR expression and becoming anchored to the cell membrane. This may be done.

[0180] In some embodiments, retroviral delivery of chimeric single chain antibody constructs (scFv) is used. This allows the generation of TCRs with defined antigen specificity, e.g., mTCRs. In a further embodiment, the chimeric scFv construct binds to the intracellular domain of FcR-gamma or CD3ζ. Linked to signaling domains, they can induce T cell effector functions. In CD3ζ, the domain can be combined with the signaling domain of a costimulatory molecule. In this case, antibody binding can trigger the function of effector T cells, and co-stimulatory In a further embodiment, the costimulatory molecule is CD28, 4-1 You can choose from BB and OX40.

The antigen is recognized through the antigen recognition site of the chain. The CD3 and zeta chains are expressed in the cytoplasm of immune cells where such TCR complexes are expressed. signal to induce functional activation.

[0182] In some embodiments, the intracellular signaling domain further comprises a co-stimulatory molecule derived intracellular signaling domain. In some embodiments, the promoter may comprise one or more functional signaling domains. The molecule may be the zeta chain of the TCR described above.

[0185] 3.3 Two-in-one vector components As provided herein, dual-function vectors can be used to inhibit immune cell function. one or more types of short hairpin RNA (shRNA) that inhibit the expression of one or more genes that attenuate ) and a chimeric antigen receptor (CAR) or T cell receptor (TCR) , for example, a nucleotide sequence encoding a monoclonal T cell receptor (mTCR).

[0186] In some embodiments, the two-in-one vector is used for insertion into the host cell genome. In some embodiments, the nucleic acid sequence may include a sequence encoding a factor that facilitates the insertion of the nucleic acid sequence. In some embodiments, the sequences are located at one or both ends of the vector gene. The sequence is an LTR (long terminal repeat).

[0187] In some embodiments, the two-in-one vector is a vector as described above. Contains a domain encoding a protein used for purification of cells into which the insert is carried In some embodiments, the domain is a ΔLNGFR domain, wherein: ΔLNGFR is a cytoplasmic nucleotide sequence used to purify cells carrying the insertion described above. It is a domainless LNGFR (low affinity nerve growth factor receptor).

[0188] In some embodiments, the dual-function vector is characterized by persistent expression. A promoter that drives the expression of both ΔLNGFR and CAR, such as the promoter shown in FIG. 22A The EF1α promoter induces the expression of both ΔLNGFR and CD19 CAR as shown in In a further embodiment, the ΔLNGFR and CD19 CAR are first transcribed in a form in which they exist on a single mRNA. In such embodiments where the above cistron is present, an IRES (internal ribosome entry site) ) may be inserted between them to cause expression of both cistrons. However, it has been reported that excessively long IRES reduces the expression efficiency of downstream cistrons. In some embodiments, components other than an IRES, such as P2A (2a peptide), are used. This drawback can be overcome by using a ribosome-specific C2A fragment. It passes through without forming a peptide bond at the end, allowing the downstream gene to be expressed later.

For shRNAs that are processed specifically to become siRNAs, some mutations, especially at the 5' end, are present. The mutation is tolerated, resulting in normal knockdown of the target gene and gene silencing. siRNA and shR are designed to have structures similar to miRNAs that play a role in signaling. It has been reported that NA mutations induce more effective target gene knockdown. Furthermore, in using vectors, it is obvious to those skilled in the art that Variation, i.e., in the cloning process to introduce specific sequences into a vector additions, modifications or deletions of base sequences that may occur or that may prevent the intended gene from being expressed. The modification or introduction of components to improve the usability of the vector to a certain extent.

Before about day 8-9, the T cell population is composed primarily of TH cells, whereas after about day 8-9, the T cell population is composed primarily of TH cells. From day 9 onwards, the population of T cells comprises a progressively larger population of TC cells. Depending on the purpose of treatment, it may be useful to inject a T cell population that is predominantly composed of TH cells into the subject. Similarly, if an antigen-specific subset of TC cells has been isolated, It may be beneficial to expand this subset to a greater extent. In addition to the D4 and CD8 markers, other phenotypic markers are expressed during the cell proliferation process. Although the changes are significant, most of them are reproducible. This allows for the ability to tailor activated T cell preparations for specific purposes.

The culture medium may be, for example, hCD32 and 4-IBB in the presence of anti-CD3 and anti-CD28 antibodies. They were then restimulated with K562 cells expressing L (K562-BBL-3 / 28). Exogenous IL-2 is added to the cultures at 100 IU / ml every other day, followed by washing. T cells are enumerated by flow cytometry using a bead-based count. For example, Milone, et al., Molecular Therapy, 17(8 ):1453-1464 (2009). CAR+ T cells in the absence of restimulation Sustained proliferation of the cells can also be measured.

[0219] Assessment of cell proliferation and cytokine production can be performed using the methods described, for example, in Milone, et al., M Ocular Therapy, 17(8):1453-1464(2009) Briefly, assessment of CAR-mediated proliferation was performed using microtiter platelets. Washed T cells were plated with target cells, e.g., K562-Meso, Ovcar3 , Ovcar8, SW1990, Panc02.03 cells or CD32 and CD137 (KT32-BBL) at a final T cell:target cell ratio of 1:1 These signals support long-term ex vivo CD8+ T cell proliferation, and anti-CD 3 (clone OKT3) and anti-CD28 (clone 9.3) monoclonal antibodies were used as KT3 It was added to cultures with 2-BBL cells to serve as a positive control for stimulating T cell proliferation. CountBright™ fluorescent beads as described by the manufacturer (Invitrogen, Carlsbad, CA) and flow cytometry. T cells are counted in the culture. CAR+ T cells express CAR linked to eGFP-2A. Using T cells engineered with lentiviral vectors expressing GFP, The expression of CD4+ and CD8+ on T cells is identified by specific monoclonal antibodies ( Cytokine measurements were also performed by BD Biosciences.

Something like that 51 It can be evaluated by Cr release assay (Milone, et al. ,Molecular Therapy,17(8):1453-1464(2009) Briefly, target cells (e.g., BHK or CHO cells) are injected with 51Cr (NaCr O4, New England Nuclear, Boston, MA) at 37°C for 2 h. Load into a microtiter plate, wash twice with complete RPMI, and mix frequently between plates. Effector T cells are generated at various effector:target cell ratios (E:T). Mix with target cells in the well in whole RPMI. Add an additional well containing medium only (natural release, SR) or a solution of 1% triton-X 100 surfactant (total release, TR) After incubation at 37°C for 4 hours, the supernatant from each well is collected. , released 51 Cr is measured using a gamma particle counter (Packard Instrument Co., Waltham, MA). Each condition was performed in at least triplicate.

[0228] Acute leukemia is characterized by the rapid proliferation of immature blood cells. This overcrowding causes the bone marrow to The body is unable to produce healthy blood cells. Acute forms of leukemia can occur in children and young adults. In fact, it is a more common cause of death among American children than any other type of malignancy. Acute leukemia requires immediate treatment due to the rapid progression and accumulation of malignant cells. The malignant cells then spill into the bloodstream and spread to other organs of the body. Although involvement is rare, the disease can occasionally cause cranial nerve palsies. It is distinguished by the excessive accumulation of mature but still abnormal blood cells. It takes months to years for the cells to develop, and they are produced at a much faster rate than normal cells, As a result, there are many abnormal white blood cells in the blood. Chronic leukemia occurs mainly in older people, but Theoretically, it can occur at any age. Acute leukemia requires immediate treatment, whereas However, chronic forms should be monitored for some time before treatment to ensure maximum effectiveness of treatment. In addition, the disease affects certain types of bone marrow cells that normally progress to form lymphocytes. Lymphocytic or lymphoblastic, which indicates that cancerous changes have occurred, and usually erythroid, Cancerous changes occur in certain types of bone marrow cells that go on to form certain types of white blood cells, platelets. Classified as bone marrow-originated or myeloid (see Lymphoid and Myeloid Cells) indicating can be.

[0229] Acute lymphocytic leukemia (also known as acute lymphoblastic leukemia, or ALL) is a small It is the most common type of leukemia in children. The disease also occurs in adults, especially those over 65. Chronic lymphocytic leukemia (CLL) occurs most commonly in adults over the age of 55. Acute myeloid leukemia (AML) occurs occasionally in young adults but rarely in children. Myeloid leukemia (AML), also known as leukemia, occurs more often in adults than in children. This type of leukemia was previously called "acute nonlymphocytic leukemia." Chronic myeloid leukemia (CML) ) occurs primarily in adults. A small number of children also develop the disease.

[0230] Lymphomas originate in lymphocytes (a type of white blood cell in the immune system of vertebrates). There are many types of lymphoma. According to the National Institutes of Health, Hodgkin's lymphoma accounts for approximately 5% of all cancer cases in the United States, and Hodgkin's lymphoma accounts for approximately 10% of all cancer cases in the United States. It accounts for less than 1% of all cancer cases. The lymphatic system is part of the body's immune system, so H Patients with weakened immune systems due to IV infections or certain medications or drugs are also at higher risk of developing lymphoma. Has an incidence rate.

[0231] In the 19th and 20th centuries, it was discovered by Thomas Hodgkin in 1832, This disease was called Hodgkin's disease. Colloquially, lymphoma is divided into Hodgkin's lymphoma and non-Hodgkin's lymphoma. Lymphoma is broadly classified as lymphoma (all other types of lymphoma). The classification is more detailed. The older classification referred to histiocytic lymphoma, but these are now classified as B, T, and Or they are recognized in a newer classification as being of the NK cell lineage.

[0232] Patients with cancers that express a target molecule of a CAR or TCR, e.g., mTCR When the pharmaceutical composition is administered to the patient, the pharmaceutical composition contains a gene that weakens the function of immune cells related to cancer cells. It does not activate genes and is caused by the activation-inhibitory signal transduction that it induces. These cells can recognize cancer and have immune activity without problems like exhaustion.

[0233] In some embodiments, the pharmaceutical composition comprising immune cells is an immune checkpoint inhibitor. The expression of the chimeric antigen receptor can be more effectively suppressed while at the same time This can maximize the effectiveness of anti-cancer immune cell therapy. In embodiments, the expression of an immune checkpoint receptor is inhibited as described above. The cells are used in pharmaceutical compositions, and other inhibitors of immune checkpoint receptors are also Severe and potentially life-threatening conditions such as cytokine release syndrome or autoimmune conditions that may result from the use of and the increased costs of treatment resulting from the combination of expensive antibody therapy with cell therapy. It is possible to eliminate the burden of the increase.

[0234] In addition to the cells, other pharmaceutically acceptable salts, carriers, excipients that may further improve the immune response. It is obvious that vehicles and other additives may be added to the pharmaceutical composition. A detailed description of the above should be omitted.

[0235] In some embodiments, the pharmaceutical composition comprises two immunosuppressants as described herein. These include dual CAR-T cells that target checkpoints. For example, dual immune checkpoint The objective of this study was to investigate the role of PD1 (programmed cell death protein 1), PD-L1 (programmed cell death ligand 1), and 1), CTLA4 (cytotoxic T lymphocyte-associated protein 4), TIM-3 (T cell immune response immunoglobulin and mucin domain-containing-3), CEACAM (3 subtypes of CEAC Carcinoembryonic antigen-related cell adhesion molecules, including AM-1, CEACAM-3, or CEACAM-5 ), LAG3 (lymphocyte activation gene 3), VISTA (V domain I of T cell activation) g suppressor), BTLA (B and T lymphocyte attenuating factor), TIGIT (Ig and IT T cell immunoreceptor with IM domain), LAIR1 (leukocyte-associated immunoglobulin-like receptor CD160 (cluster of differentiation 160), CD96 (cluster of differentiation 96), MerTK (proto-oncogene tyrosine protein kinase MER), and 2B4 (NK cell activation-inducing ligand and PD1 and TIM3. That's fine.

[0236] In some embodiments, the type of immune checkpoint targeted determines the anti-tumor efficacy of the pharmaceutical composition. For example, pharmaceutical compositions targeting PD-1 and TIM3 may affect the efficacy of PD-1. and can exhibit a different level of antitumor effect from pharmaceutical compositions targeting TIGIT. In a further embodiment, the difference in anti-tumor effect is due to the same immune checkpoint unpredictable from known knowledge about the antitumor effects of other drugs targeting e.g. Other agents include antibodies that target immune checkpoints. In fact, targeting two specific immune checkpoints has surprisingly potent antitumor effects. In an exemplary embodiment (Example 10), PD-1 and TIG CAR-T cells targeting IT bind to PD-1 and CTLA-4, PD-1 and LAG-3, and and other dual-KD CAR-T cells targeting a combination of PD-1 and TIM-3. It shows surprisingly excellent antitumor effects.

[0272] Example 1: Two-in-one function by expressing CART19 and shRNA targeting PD-1 Methods for constructing and evaluating functional vectors This example demonstrates the use of a two-in-one mouse model expressing CART19 and an shRNA that inhibits PD-1. This paper describes methods for constructing and evaluating vectors with two functions.

[0273] Dual-function lentivirus encoding both CAR and shRNA expression cassettes To generate viral vectors, shRNA (linking sequence; TTCAAGAGA, end sequence; TTTTT) and a Pol III promoter (mU6, hU6, or hH1). Synthesize an shRNA expression cassette containing the nucleotide sequence upstream of the central polypurine tract (cPPT). The CAR was subcloned into an LV vector encoding the EF-1α promoter. Therefore, 4-1BB-based CART19 was targeted to PD-1 by the mU6 promoter. We constructed a lentiviral vector that spontaneously expresses shRNA targeting the target gene (Figure 1A and 1B). B).

[0274] Three shRNA candidates were used to select shRNAs targeting PD-1. shPD-1#1 significantly increased CAR expression (Figure 1C), homeostatic proliferation (Figure 1D), differentiation status, and C PD-1 expression (Fig. 1F) without affecting the D4 / CD8 composition (Fig. 1F). The expression level of shRNA was significantly higher than that of Pol III protease inhibitors. It has been reported that this may vary depending on the type of motor (Mol. Ther. ,2006,Irvin SYChen). Therefore, the mU for PD-1 expression The effects of the mU6, hU6, or hH1 promoter were evaluated. mU6 and hu6 had similar KDs. hH1 showed efficacy, but hH2 was even less effective (Figure 2).

[0275] The dual-function lentiviral vector constructed here is capable of expressing PD-1. Therefore, the PD-1 KD modified C was used in the following examples. It can be used to generate AR-T cells.

[0276] Example 2: Method for producing PD-1 KD CAR-T cells and in vitro evaluation This example describes the method for producing PD-1 KD-modified CAR-T cells and their in vitro evaluation. It is listed.

[0277] Peripheral blood mononuclear cells were cultured using Ficoll-Paque Plus (GE Healthcare e) These cells were isolated from whole blood samples of healthy donors by density gradient centrifugation. 4 μg / ml in the presence of 300 IU / ml human recombinant IL-2 (BMIKOREA) Plate-bound anti-CD3 antibody (clone OKT3; Bio X cell) and 2 μ The cells were stimulated with 1 μg / ml of soluble anti-CD28 antibody (clone CD28.2; Bio X cell). For recombinant lentivirus production, 2.5 mL of growth medium was added 24 hours before transfection. Culture medium (10% FBS, 2 mM L-glutamine, 0.1 mM non-essential amino acids, and 1 mM 6x10 in DMEM (supplemented with M sodium pyruvate) 5 6 293T cells The cells were seeded in a well plate. 10 μl of Lipofectamine 2000 (Ther Using mofisher, packaging vectors (pMDL, pRev, pMDG Two days after transfection, the lentils were transfected with a mixture of .1) and transfer vector. The virus-containing culture supernatant was collected and centrifuged at 1800 rpm for 5 minutes. The cells were mixed with the viral supernatant in the presence of protamine sulfate (1 μg / ml) and centrifuged at 1000 × g. The mixture was centrifuged for 90 minutes and incubated overnight at 37°C. The next day, the culture supernatant was aspirated and diluted with 10% F BS, 2 mM L-glutamine, 0.1 mM non-essential amino acids, 1 mM sodium pyruvate The mixture was then mixed with fresh RPMI-1640 supplemented with 55 μM sodium and 55 μM β-mercaptoethanol. 1 × 10 transduced T cells were 6 10% heat-inactivated at a density of less than 10 cells / mL Supplemented with activated FBS, 2 mM L-glutamine, and 1% penicillin / streptomycin. RPMI-1640, containing human recombinant IL-2 (300 IU / mL), T cells The cells were cultured in medium, which was replenished every 2–3 days.

[0278] The in vitro lytic and proliferative activities of shPD-1 CAR-T cells were examined. m-6-PDL1 or K562-CD19-PDL1 to CD19 + PDL1 + target cell First, we used the IncuCyte real-time imaging system. Long-term lytic activity was investigated. When CAR-T cells were mixed with NALM-6 cells, WT (s hGFP) CAR-T cells and PD-1 KD (shPD-1) CAR-T cells had similar lytic activity. However, when CAR-T cells were cultured with NALM-6-PDL1 cells, When compared with the shPD-1 CAR-T cells, the lytic activity of the shGFP CAR was surprisingly higher. Unexpectedly, BBz containing no shRNA cassette showed effective lytic activity (Fig. 3A). CAR-T cells and shGFP CAR-T cells were also found to have similar cytotoxicity. This suggests that shRNA expression itself has little effect on CAR-T cell activity. This suggests that it does not have

[0279] Next, we investigated the proliferative activity of CAR-T cells repeatedly exposed to CD19 antigen and PD-L1. shPD-1 CAR-T cells expressed shGFP C in the absence of exogenous IL-2. 4-5 times higher T cell response to K562-CD19-PDL1 targets than AR-T cells Costimulatory ligands promote optimal T cell proliferation and tumor proliferation (Figure 3B). It is known that it is not rare for tumor cells to express co-stimulatory ligands in target cells. To investigate whether expression of endothelin affects cell proliferation upon repeated stimulation, a representative We investigated whether the costimulatory ligand CD80 was expressed on target cells. D19 expressed CD80 but not Nalm-6 (Fig. 3C). Overexpression of NALM-6-PDL1 (NALM-6-PDL1-CD80) inhibits repeated stimuli. CD80 was found to enable CAR-T cells to proliferate under stimulation. It may promote CART proliferation under repeated in vitro stimulation (Figure 3B). Cell-intrinsic PD-1 disruption is associated with CD19-specific CAR activation upon repeated stimulation with CAR and PDL1. This demonstrates that it contributes surprisingly effectively to improving the function of RT cells in vitro.

[0280] In this example, the two-in-one vector described in Example 1 was used. The generated PD-1 KD-modified CAR-T cells showed improved in vitro performance compared with WT CAR-T cells. The therapeutic potential of the compound has been demonstrated by demonstrating a surprising level of enhanced lytic and proliferative activity in the cells. However, CD19 in the following examples + PDL1 + in a mouse model bearing hematologic tumors It was further evaluated in an in vivo model.

[0281] Example 3: CD19 using PD-1 KD CAR-T cells + In vivo blood cancer Treatment method This example demonstrates the use of PD-1 KD CAR-T cells to target CD19 + Blood cancer in vivo The treatment method is described.

[0282] CD19 + To establish a hematological cancer model, NSG mice (4-6 weeks old) were treated with EGF. 1x10 engineered to express P-fused firefly luciferase and human PDL1 6 pieces CD19 +NALM-6 leukemia cells (NALM6-GL-PDL1 cells) were injected intravenously. CAR-T cells were isolated from whole blood samples of healthy donors according to the procedure described above. Four days after transduction, CAR - T cells were sorted and further purified prior to injection into mice. Five days after injection of NALM6-GL-PDL1 cells, 1 × 10 6 pieces CAR-T cells were intravenously injected into mice. Bioluminescence imaging was monitored with Xenogen IVIS Spectrum and signals The images were analyzed using Living Image software (Perkin Elmer). The radiance was quantified as photons / second in the area of ​​the shPD-1 CAR-T cells. Mice treated with shGFP CAR-T cells showed a strikingly uniform tumor burden compared to shGFP CAR-T cells. In addition, the promoters expressing the two types of shRNAs had similar anti- It was found that shRNA expression itself surprisingly did not affect the antitumor effect. It was offered.

[0283] To investigate the effect of cell-intrinsic PD-1 disruption in CAR-T cells on cytokine production in vivo. Peripheral blood from individual mice was obtained 24 and 72 hours after CAR-T injection. Plasma was collected from peripheral blood by centrifugation at 300 × g for 5 minutes at room temperature. Cytokine levels in the rats were measured using a human Th1 / Th2 cytokine kit according to the manufacturer's instructions. The cell-specific PD-1 expression of CAR-T cells was analyzed using a CT scan (BD Bioscience). The necrosis unexpectedly reduced cytokine production in vivo (Figure 5A).

[0284] Effect of cell-intrinsic PD-1 disruption on CAR-T cell proliferation in vivo To examine the effect, spleens from individual mice were obtained 3 or 20 days after CAR-T injection. CAR-T cells (live cells / dead cells) ― CD3 + ) or NALM-6-PDL1 (live cells / dead cells ― GFP + The ratio of cell-intrinsic PD-1 disruption was assessed by flow cytometry. unexpectedly delayed the in vivo expansion of CAR-T cells ( Fig. 5B ).

[0285] obtained by the dual-function vector system described herein. CAR-T cell-intrinsic PD-1 disruption inhibits CD19 + PDL1 + CD19 specificity for tumors The results showed an unexpectedly high increase in the in vivo antitumor effect of allogeneic CAR-T cells. The PD-1 KD CAR-T cells were further used in the methods described in the following examples.

[0287] Cell-intrinsic PD-1 disruption is associated with CD28 / CD3ζ or 4-1BB / CD3ζ CAR- We investigated how G28z and GBBz affect T cell function (Figure 6A). P28z and PBBz CAR-T cells were first generated. The PD-1 expression level was significantly higher in G28z CAR-T cells than in G28z CAR-T cells (Figure 6B). The PD-1 levels of P28z were higher than those of GBBz CAR-T cells, and P28z PD-1 levels were higher than those of PBBz The differential PD-1 protein levels were also higher (Fig. 7A). Each costimulatory domain inhibits the activity of factors involved in PD-1 transcription. We hypothesized that these factors may express different potencies for PD-1 transcription. NFAT and NF-κB are highly involved in PD-1 transcription, and SMAD2 / 3 are involved in tumor microenvironment. It is involved in PD-1 transcription in the presence of exogenous TGF-β, a major immunosuppressive factor in the environment. (Cancer Discov., 2016, Benjamin, V. Park). NFAT or NF-κB activity was examined during CAR stimulation. T-RE ×3)-eGFP or classical NF-κB response element (NF-κB RE ×5) )-eGFP reporter lentiviral vectors were constructed. The BRE was shown to mediate eGFP induction (Figures 8A and 8B). The transduced T cells were restimulated and further transduced with G28z or GBBz. Transduced NFAT reporter CAR-T cells (G28z-NFAT) were transduced with GBBz-NF NFAT activity was slightly higher than that of AT (Fig. 9A), indicating that NFAT target genes The mRNA levels of α-glucan were also higher in G28z (Fig. 9B). G28z-transduced NF-κB reporter CAR-T cells (G28z-NF-κB) NFAT activity was similar compared to BB-NF-κB (Figure 10). To examine the activity of SMAD2 / 3 in T cells, TGF-β stimulated G28z during CAR stimulation. or GBBz CAR-T cells. Phosphorylation of BBz CART was slightly higher (Fig. 11A), and PD-1 phosphorylation was significantly higher with TGF-β treatment. The degree of increase in expression was greater in G28z than in GBBz (G28z 2.39±0.0 31, GBBz 1.61 + 0.034 fold change) were found (Figure 11B). We investigated whether this difference was due to differences in the expression levels of TGF-β signaling components. TGF-β and TGF-β receptor 1 (TGFBR1) showed no significant differences between the two CARTs. TGF-β receptor 2 (TGFBR2) was expressed at even higher levels in CD28z. It was found to be expressed in the bell (Fig. 11C).

[0288] In this example, costimulation involving CD28 and 4-1BB in PD-1 signaling We assessed the molecular milieu. CD28 costimulation strongly induced signaling associated with PD-1 transcription. The induction may be associated with activation of NFAT and TGF-β signaling. The induction of 8-costimulation was stronger than that of 4-1BB-costimulation.

[0289] Example 5: Engineering and evaluation of PD-1 KD CAR-T cells This example describes the engineering and evaluation of PD-1 KD CAR-T cells.

[0290] CAR-T cell activation with multiple sequential antigen and immune checkpoint ligand encounters To mimic the in vivo condition, CAR-T cells were transfected with CD1 9 + PDL1 + Primary CAR-T cells were co-cultured with target cells. The CAR-T group showed surprisingly higher lytic activity than the WT CAR-T group, but CD28 There was no difference in lytic activity between the 4-1BB and 4-1BB CAR-T groups (Figure 12A). After restimulation of CAR-T cells in the eye, G28z CAR-T cells proliferate after the second stimulation After losing potency, the lytic activity of the three CAR-T cells was analyzed: PBBz and P28z CAR-T cells were more effective against repeated antigen and PD-L1 exposure than GBBz CAR-T cells. PBBz CAR-T cells showed surprisingly high lytic activity compared with P28z CAR- They showed an unexpectedly higher ability to retain lytic function than T cells (Fig. 12A). The effect was also observed in cell proliferation assays (Figure 12B). The application of the 4-1BB costimulatory domain to ART has been shown to be more effective than the CD28 costimulatory domain. This contributes to the retained cytotoxicity and proliferation capacity in vitro. PBBz CAR-T cells Repeated exposure to CD19 and PD-L1 shows delayed exhaustion.

[0291] We investigated the possible influence of immunosuppressive mechanisms on BBz CAR-T cells. Because AR-T cells were more sensitive to TGF-β than BBz CART ( Figure 1 1) To what extent TGF-β inhibits antigen-specific proliferation, GBBz C CAR-T cells were compared with G28z CAR-T cells. During stimulation, no significant difference in proliferation was observed between the two CAR-T cells, while GBB The proliferation of G28z CAR-T cells, but not z CAR-T cells, was significantly reduced. (Figure 13A).

[0292] TGF-β not only inhibits proliferation but is also deeply involved in the induction of regulatory T cells. It has been reported (JEM, 2003, WanJun Chen; Science, 2 003, Shohei Hori; Blood, 2007, Dat Q. Tran). outside Between G28z and BBz CAR-T cells in the absence of TGF-β To investigate whether Treg induction differs, G28z CAR-T cells and BBz CAR-T cells were cultured with NALM-6 target cells for 3 days. G28z CAR-T cells Two to three times higher in vitro CD4 T cell counts compared to GBBz CAR-T cells + CD25 + F OXP3 + The results showed that the expression of CD25 and FOXP3 was significantly higher in the Treg cells (Figure 13B). This coincides with the increased expression of Treg-related genes (Fig. 9B). The changes in Treg% after treatment were observed and compared. TGF-β was significantly elevated in 28z CAR-T cells. BBz CAR-T cells significantly improved Treg%. It was shown that CD28 costimulation stimulated Tregs more effectively than 4-1BB costimulation (Fig. 13B). The results showed that TGF-β has a high potential for induction of inflammatory cytokines, and that this potential is even more pronounced in the presence of TGF-β. We also investigated whether cell-specific PD-1 disruption affects Treg induction. P28z CAR-T cells and PBBz CAR-T cells were compared with G28z and GBBz. In particular, PBBz had the lowest Treg %. % (Figure 13C). Finally, PD-1 / PD-L1 signaling was activated. The proportion of Tregs in the presence of NALM-6 or NALM-6-PDL1 was examined. The change in Treg% after culture was examined. PD-1 / PDL1 signaling was CAR-T-derived. It was found that there was no significant effect on the induction of Tregs (Fig. 13C). These results suggest that the expression level of intracellular PD-1 is related to the formation of Tregs. It was concluded that Bz CAR-T cells may be surprisingly insensitive to immunosuppressive mechanisms. .

[0293] In this example, PBBz CAR-T cells were generated, which express CD19 and PD-L Repeated exposure to PBBz CAR-T cells demonstrated delayed exhaustion. These cells unexpectedly evade the tumor suppressor, thus providing further insight into their antitumor effects in vivo. It was appreciated.

[0294] Example 6: In vivo treatment of CD19+ blood cancers using PBBz CAR-T cells This example demonstrates the in vivo treatment of CD19+ hematologic cancers using PBBz CAR-T cells. The method is described.

[0295] CD19 + A hematological tumor model was established as described in Example 3. + BA In vivo treatment of G28z, GBBz, P28z, and PBBz CAR-T cells against LL cells The antitumor effects of CAR-T cells were compared between 2.5 × 10 6 In vivo imaging of mice bearing NALM6-GL-PDL1 The process is performed using Xenogen IVIS Spectrum, which measures the radiance of the target area. As shown in Figure 14, PD-1 KD CART cells ( PBBz or P28z) than WT CAR-T cells (GBBz or G28z). In particular, PBBz CAR-T cells showed superior antitumor effects compared to the other three CAR-T cells. WT CAR-T cells suppressed leukemia progression for a longer period than WT CAR-T cells. However, PD-1 KD CAR-T showed no durable antitumor response. Although the response to CAR-T cells was weak, the sustained antitumor response was significant. These results suggest that disruption of PD-1 in cells may reduce the risk of CRS. PBBz CAR-T cells showed unexpectedly superior in vivo efficacy compared with P28z. It conferred antitumor effects.

[0296] Example 7: Two-in-one with two shRNA cassettes inserted in →← or ←→ directions Method for constructing a dual vector with the functions of This example describes how to create a dual vector with two functions in one.

[0297] shRNA for PD-1 (hereafter referred to as shPD-1), shRNA for TIM-3 ( The expression of shTIM-3 and CD19-CAR was controlled by the human U6 promoter (hereafter referred to as hU6 (hereafter referred to as "mU6"), mouse U6 promoter (hereafter referred to as "mU6"), and EF1-α promoter To construct a lentivirus that is regulated by the shRNA gene, both types of shRNA are expressed simultaneously. The resulting plasmid contains shRNA cassettes in the →←direction (mU6-shTIM-3 →←shP D-1-hU6) and in the ←→ direction (shTIM-3-mU6←→hU6-shPD-1).

The restriction enzyme recognition site is BsgZ171-Xba1-Nde-1-Bmt1-Spe1 multiclone A PCR product (416 bp) was generated that was modified to the cloning site. was digested with BstZ17y and Hpa1 restriction enzymes, and plasmid ID#2 was digested with Hpa1 restriction enzyme. After treatment with ribosomal DNA and CIP, shPD-1-mU6-MC was synthesized using blunt-end ligation. pLV-ΔLNGFR-P2A containing the S base sequence (shRNA cassette SEQ ID NO: 223) -CD19-CAR-mU6-shPD-1_MCS (Plasmid ID#4) was prepared. .

[0299] Then, shPD-1 was expressed by the human U6 promoter instead of the mouse U6 promoter. The plasmid was constructed so that it could be expressed by the LentiCRISPR V2 plasmid. was used with primers containing SEQ ID NOs: 230 and 231 to identify a gene encoding a human U6 promoter. The PCR product was digested with Hpa1 and Spe1 restriction enzymes and then purified with Hp This was ligated with plasmid ID#4 treated with a1 and Spe1 restriction enzymes to give hU6 -pLV-ΔLNGFR_P2A_CD containing shPD-1 base sequence (SEQ ID NO: 224) 19-CAR_hU6-shPD-1_MSC (Plasmid ID#5) was prepared. 6-shTIM-3 cassette was inserted into plasmid ID#5 to generate shTIM-3 and shPD The aim of this study was to construct a plasmid that simultaneously expresses α- and β-actin.

[0300] The PCR product containing the mU6-shTIM-3 cassette was identified as plasmid ID#3 and SEQ ID NO: The PCR product was obtained using primers containing 232 and 233. After digestion with restriction enzymes, plasmid ID#5 was digested with Bmt1 and Spe1 restriction enzymes. The resulting fragments were ligated in the →← direction (mU6-shTIM-3 →←shPD-1-hU 6) pLV-ΔLNGFR_P2A_CD19-C containing the base sequence (SEQ ID NO: 220) AR mU6-shTIM-3 → ← shPD-1-hU6 (Plasmid ID#6) was prepared. did.

[0301] Two types of shRNA cassettes are arranged in the ←→ direction (shTIM-3-mU6←→hU6-shP D-1), plasmid ID#6 and SEQ ID NO: A PCR product was obtained using primers containing 234 and 235. Spe1 and Hpa1 After digestion with restriction enzymes, it was inserted into plasmid ID#4 which had been digested with the same restriction enzymes to form p LV-ΔLNGFR-P2A-CD19-CAR-shPD-1-hU6-MCS (Plastic Plasmid ID#6 and SEQ ID NOs: 236 and 237 were then prepared. PCR products were obtained using primers containing the following: After digestion with the enzymes, plasmid ID#7 and its corresponding plasmids were digested with Bmt1 and Spe1 restriction enzymes.

[0302] Two types of shRNA cassettes were prepared in this study and inserted in either the left-right or right-left direction. The lentiviral vector with two functions is the PD-1 KD modified C It can be used to generate AR-T cells.

[0303] Example 8: Method for producing PD-1 KD CAR-T cells and in vitro evaluation This example demonstrates the simultaneous expression of shPD-1, shTIM-3, and CD19-CAR. We describe a method to generate and evaluate in vitro double-KD CAR-T cells.

(PBMC) were isolated from human blood and T cells were cultured using human CD3 and CD28 targeting antibodies. One to two days after the initial activation of T cells, the previously obtained virus The prepared CAR-T cells were then transduced using 5% human plasma and human plasma. Six days after transduction, the cells were cultured in AIM-V medium containing human IL-2. Using the lect LNGFR system (miltenyibiotec, Germany) Pure CAR-T cells were obtained using a flow cytometer with an antibody targeting LNGFR. LNGFR+CAR-T cells were isolated using the following plasmids ID#1, #6, and # Cells prepared using 8 were ΔLNGFRCART19 / shGFP (or s hGFP / CART19), ΔLNGFR-CART19 / mU6-shTIM-3→← shPD-1-hU6 (or shPD-1_shTIM-3 / CART19) and ΔL Denoted as NGFR-CART19 / shTIM-3-mU6←→hU6-shPD-1 (Figure 16).

[0305] The mU6-shPD-1, mU6-TIM-3, and shPD-1-hU6 cassettes were To prepare control CAR-T cells containing each of the CAR-T cells, lipofectamine was used to prepare the CAR-T cells containing the CAR-T cells listed in Table 1. Plasmid ID#2 (pLV-ΔLNGFR_P2A_CD19-CAR_mU6-s hPD-1), #3(pLV-ΔLNGFR_P2A_CD19-CAR_mU6-sh TIM-3), and #7 (pLV-ΔLNGFR_P2A_CD19-CAR_shPD -1-hU6_MCS), and packaging plasmids pMDL g / p and pRSVr HEK293T cells were transfected with ev and pMDG.1. After 48 hours, lentil A cell culture solution containing the virus was obtained. PBMCs were isolated from human blood and T cells were cultured using human CD3 and CD28 targeting antibodies. One to two days after the initial activation of T cells, the previously obtained virus was injected into the infected cells. The prepared CAR-T cells were then transduced using 5% human plasma and The cells were cultured in AIM-V medium containing human IL-2. Six days after transduction, the cells were cultured in a MACS elect LNGFR system (miltenyibiotec, Germany) Obtain pure CAR-T cells using a flow cytometer with an LNGFR-targeting antibody LNGFR+CAR-T cells were isolated using the plasmid ID#2, #3, and The cells prepared using #7 were ΔLNGFR-CART19 / shPD-1 (or or shPD-1 / CART19), ΔLNGFR-CART19 / shTIM-3 (or or shTIM-3 / CART19) and ΔLNGFRCART19 / shPD-1-h Denoted as U6.

[0306] To measure the purity of the double KD CAR-T cells generated herein, the above-prepared The cells were subjected to flow cytometry using an antibody targeting LNGFR. As shown, approximately 80% LNGFR+ CAR-T cells were obtained.

[0307] Expression of PD-1 and TIM-3 in the double KD CAR-T cells generated herein The double KD CAR-T cells were used to measure the decrease in expression of CAR-T cells, and a sustained decrease in expression was observed. Stimulation with human CD3 and CD28 targeting antibodies for 3 days induced the expression of PD-1 and TIM-3. This was followed by flow cytometry analysis using antibodies targeting CAR, PD-1, and TIM-3. We analyzed PD-1 and TIM-3 expression in double KD CAR-T cells via a cytometry analysis. As shown in Figures 18A and 18B, two similar responses to the downregulation of PD-1 and TIM-3 expression were observed. Analysis of the effect of the type of shRNA expressed at the time of shPD-1 and shTIM-3 Low PD-1 and TIM-3 expression observed in CD19-CAR-T cells expressing CD19 The lower level indicates CD19-CAR- The degree of reduction was similar to that in T cells.

[0308] The effect on differentiation of the double KD CAR-T cells generated herein was measured. To observe the degree of differentiation of PD-1 and TIM-3 in KD CAR-T cells, CD4 Flow cytometry was performed using 5RA and CCR7 targeting antibodies. Thus, in ΔLNGFR-CART19 / shPD-1 cells subjected to repeated antigen stimulation, Terminally differentiated TEMRA (CCR7-C On the other hand, ΔLNGF, which contains shTIM-3, increases the number of T cells. R-CART19 / mU6-shTIM-3→←shPD-1-hU6 is ΔLNGFR -more TN (CCR7+CD45RA+) T cells than CART19 / shPD-1; TCM(CCR7+CD45RA-)T cells and TEM(CCR7-CD45RA-)T Similar results were observed in ΔLNGFR-CART19 / shTIM-3 cells. This is also observed in ΔLNGFR-CAR cells, suggesting that the suppression of TIM-3 expression is responsible for the ΔLNGFR-CAR The reduced differentiation potential of T19 / mU6-shTIM-3 → ← shPD-1-hU6 cells Therefore, the effect of shTIM-3 on cell differentiation is more pronounced than that of shPD-1. It can be said that it has been prioritized in terms of its impact on the It is known that cell subtypes can enhance the cancer-fighting ability of T cells, so Δ LNGFR-CART19 / mU6-shTIM-3 →←shPD-1-hU6 cells are Δ showed better in vivo anti-cancer efficacy than LNGFR-CART19 / shPD-1 cells. It is expected that this will happen.

[0309] Two CD19-CAR vectors containing shRNA cassettes in different orientations were introduced. The transduction efficiency, proliferation capacity, and survival rate of the heavy KD CAR-T cells were compared. Among the CAR-T cells generated, the →←direction (mU6-shTIM-3 →←shPD-1 -hU6) and ←→ direction (shTIM-3-mU6←→hU6-shPD-1) cassettes Flow cytometry was performed using LNTFR antibodies on cells containing the plasmid. For cell viability analysis, trypan blue staining was performed. As shown in Figures 20A to 20C, the ratio of cells containing →← cassette (ΔLNGFR -CART19 / mU6-shTIM-3 →←shPD-1-hU6) All, ←→ direction cassette (ΔLNGFR-CART19 / shTIM-3-mU6←→h Cells using U6-shPD-1 unexpectedly struggled to form transduced cells, The transduced T cells had poor proliferation and survival capacity.

[0310] This example describes a method for generating double KD CAR-T cells, in which s hPD-1, shTIM-3, and CD19-CAR are expressed simultaneously. The two-in-one function constructed herein has two shRNA cassettes inserted in the left-direction. We generated double KD CAR-T cells using a lentiviral vector capable of expressing CAR-T cells. Compared with cells using the →← cassette, cells using the →← cassette (ΔLNGFR -CART19 / mU6-shTIM-3 →←shPD-1-hU6) showed surprisingly high It demonstrated reproductive ability and viability and was used in the following examples.

[0311] Example 9: Method for generating dual vector and dual KD CAR-T cells with two functions in one law This example demonstrates the generation of a two-in-one vector and dual KD CAR-T cells. The method is described.

[0312] Two shRNAs expressed by different promoters (mU6 and hU6) To generate a dual vector with two functions, BstZ171-Xba1-Nde1- The multiple cloning site (MCS) of Bmt1-Spe1 was inserted downstream of the hU6 promoter. It was inserted into the pLV-hU6-shPD-1_ΔLNGFR-CD19-BBz vector. The second mU6-shRNA cassette fragment was subcloned into the MCS. Two-in-one technology to limit checkpoint blockade to CAR-T cells A vector was designed to encode two sRNAs using the mU6 and hU6 Pol III promoters. hRNA was expressed, suppressing the expression of two immune checkpoints in CAR-T cells. Effective siRs targeting CTLA-4, LAG-3, TIGIT, or TIM-3 To detect NA, siRNA was electroporated into CD3 / CD28 stimulated T cells. Two or more effective siRNAs were selected (Figure 21A). 4, with one for LAG-3, TIGIT, or TIM-3 KD CAR-T cells The dual-function vector converts 21-mer siRNA into shRNA format. Finally, shRNAs targeting each immune checkpoint (shCT LA-4:#1;shLAG-3:#1278;shTIGIT:#739;shTIM -3:#3) were selected, but they significantly suppressed expression and had little effect on CAR-T proliferation. (Fig. 21B-C). Finally, a dual vector with two functions in one PD-1_CTLA-4, PD-1_LAG-3, PD-1_TIGIT, or PD CAR-T cells of -1_TIM-3 were constructed (Figures 22A-22E). All RT cells proliferated less compared to single PD-1 KD CAR-T cells. These results were also observed with single KD CAR-T cells (Fig. 21B).

[0313] In this example, a dual vector with two functions in one was created. We will generate double KD CAR-T cells using dual vectors capable of targeting CAR-T cells and investigate their therapeutic potential. CD19 in the following examples + PDL1 + In vivo mouse models and solid tumor-bearing hematologic tumors Further evaluation was carried out in tumor models.

[0314] Example 10: C using dual KD CAR-T cells targeting PD-1 and TIGIT In vivo treatment of D19+ blood cancer This example illustrates the following combinations: PD-1 and CTLA-4, PD-1 and LAG-3, Two immune checkpoints, including PD-1 and TIGIT, and PD-1 and TIM-3, were identified. Treating CD19+ hematological cancers in vivo with targeted dual KD CAR-T cells It states the law.

[0315] The CD19+ hematologic tumor model was established as described in Example 3. Blood CD1 9 + PD-1_CTLA-4, PD-1_LAG-3, and PD- The antitumor effects of 1_TIGIT or PD-1_TIM-3 KD CAR-T cells were evaluated. Each CAR-T cell was administered at a dose of 1 × 10 6 Injected in a single dose PD-1_TIGIT KD CAR-T cells were significantly superior to other double KD CAR-T cells. It was found that the antitumor effect of the IFN-γ-α-glucan-1-phosphate dehydrogenase (IFN-γ-α) was surprisingly superior to that of the IFN-γ-α-glucan-1-phosphate dehydrogenase (IFN-γ-α) (Fig. 23). PD-1_TIGIT KD CAR-T cells in a thyroid tumor model are further described in the following examples. The results were further evaluated.

[0316] Example 11: Immunotherapy using dual-KD CAR-T cells targeting PD-1 and TIGIT Treatment strategies in tumor models. This example uses dual-KD CAR-T cells targeting PD-1 and TIGIT. The present application describes a method for treating cancer in a solid tumor model.

[0317] To establish solid tumor models, 4- to 6-week-old NSG mice were inoculated with 5 x 10 6 IM- 9 cells (CD19 + PD-L1 + CD155 + ) was injected subcutaneously. ~250mm 3 When the volume reached 3 × 10 6 Single dose intravenously Tumors were monitored weekly by caliper measurement and volume was determined (length × width). 2 ) / 2 As shown in a hematologic tumor model (Nalm-6-PDL1), PD -1_TIGIT KD CAR-T cells also showed the most surprising effect on the solid tumor model (IM-9). The more effective the blockade of cell-intrinsic PD-1_TIGIT, the more effective the blockade of PD-1. It has an unexpectedly higher level of antitumor effect than blockade.
