Title: CD229 Car T Cells And Methods Of Use Thereof

Description:
BACKGROUND 
     Multiple myeloma (MM) is an incurable plasma cell malignancy with significant morbidity and mortality. While proteasome inhibitors and immunomodulatory agents have improved rate and depth of responses, most patients will eventually relapse. Accordingly, there is an urgent medical need for more effective therapeutic strategies capable of eradicating minimal residual disease. Chimeric antigen receptors (CARs) combine an antibody domain directed against a surface antigen with signaling domains that induce T cell activation. CD229, a member of the SLAM (signaling lymphocyte activation molecule) family of proteins, is strongly expressed on both MM cell lines and primary MM cells, including chemotherapy-resistant CD19-138-pre-plasma cells. CD229 is physiologically expressed on T and B lymphocytes and natural killer (NK) cells but absent from myeloid cells, hematopoietic stem cells, and nonhematopoietic cells. Thus, a CD229-specific CAR T cell can be used to target MM cells.

         FIGS.  2 A,  2 B,  2 C,  2 D,  2 E, and  2 F  show the generation and screening of fully human monoclonal antibodies and CARs against CD229. (A) Schema demonstrating the principle of antibody phage display. After incubation of the phage library with immobilized CD229, bound phages are eluted and amplified in  E. coli . Enriched phage undergo repeated selections to provide a pool of CD229-specific antibodies for the generation of CAR constructs.

(F) Comparison of binding of 23 unique clones to CD229 in three antibody formats. (Bottom) Binding of anti-CD229 scFvs expressed in  E. coli  determined by time resolved florescence (TRF) assay. (Middle) Binding of anti-CD229 scFv-Fc antibodies expressed in 293F cells determined by TRF assay. (Top) Binding of anti-CD229 CARs expressed in 293T cells shown as mean fluorescence intensity (WI) by flow cytometry. 
         FIGS.  3 A,  3 B, and  3 C  show the activation and cross-reactivity of anti-CD229 CAR T cells. (A) Intracellular interferon gamma (IFNγ) staining of primary human T cells expressing each of 12 CAR constructs as determined by flow cytometry. Example dot plots are shown for non-reactive clone 1A2 and reactive clone 1E12. Both clones showed no significant reactivity towards immobilized BSA. A relatively low percentage of IFNγ-positive cells was expected as this assay was performed with freshly transduced CAR T cells which had not been enriched for CAR expression and only showed an average transduction rate of 20%. (B) Preliminary crossreactivity analysis of 4 randomly elected clones against human CD229 (hCD229), murine CD229 (mCD229) and four other SLAM family receptors. (C) Expansion curves of primary human T cells after lentiviral transduction of constructs expressing each of two anti-CD229 CARs or GFP alone. 
         FIGS.  4 A and  4 B  show the cytoxicity of anti-CD229 CART cells against CD229-expressing target cells. (A) Gating schema of the flow cytometry-based cytotoxicity assay used to determine activity of anti-CD229 CAR constructs. (B) T cells expressing two different anti-CD229 CAR clones (2A2 and 2D3) or GFP were incubated with K562 cells expressing CD229 (set of bars on the left of each group) or autologous untreated T cells (set of bars on the right of each group). Target cells were stained with Calcein-AM prior to the cytotoxicity assay. GFP sorted anti-CD229 CAR T cells were incubated with target cells at effector-target ratios of 0:1, 1:1, and 10:1 for 4 hours at 37° C. Target cell killing was assessed by flow cytometry. T cell clones expressing anti-CD229 CAR showed strong cytotoxic activity against K562-CD229 cells but only limited toxicity against autologous T cells. 
         FIGS.  5 A,  5 B,  5 C,  5 D, and  5 E  show the binding, cross-reactivity, and selectivity of anti CD229 CAR T cells. (A) Cross-reactivity screening of 2 anti-CD229 antibody clones expressed as scFv-Fc constructs in mammalian cells by TRF assay using recombinant SLAM family members. 2A2 shows some cross-reactivity while 2D3 is specific to human CD229 only. (B) Cytotoxic activity of primary human T cells expressing CAR constructs based on two antibodies or GFP alone against CD229 positive myeloma cell line U266 and healthy autologous T cells as determined by flow cytometry. Anti-CD229 CARs specifically kill myeloma cells but not healthy T cells co-expressing CD229. (C) Sensorgrams of 3 anti-CD229 antibodies expressed as scFv-Fc in mammalian cells using high-throughput surface plasmon resonance (SPR) and resulting (D) equilibrium and rate constants demonstrating slow on- and off-rates for all 3 clones. (E) Competition SPR using immobilized CD229 and sequential injections of the primary antibodies followed by individual injection of antibodies to determine their ability to compete for the epitope recognized by the primary antibody. IDS and 2D3 occupy the same epitope space while 2A2 binds to a distinct epitope. Due to the lack of self-competition, 2A2 most likely binds to an epitope occurring twice in recombinant CD229, a tandem Ig domain-containing protein. 
         FIGS.  6 A- 6 G  show the expression of CD229 in MM. (A) Schematic representation of clonotypic hierarchy and interconversion of myeloma plasma cells (PC), the CD138low PC population, and chemotherapy-resistant Pre-PC.

Initial gates include CD19-2-3-14-16-235a-(left), followed by gating for CD200+319+(Middle) and then differentiated into CD38+ plasma cells that are CD138-positive and -negative, respectively. (Bottom panel) Expression of CD229 in four patients with MM. Histogram represents CD38+CD138high (far right), histogram CD38+CD138low (middle) and histogram fluorescence minus one (FMO) control (far left). (C) In a clonogenic growth assay, clonal MM clusters were counted 7-10 days after culture initiation using MM cell line MOLP-8 (left) or KMS-12-BM (right). Bars indicate standard error of mean values derived from three separate experiments. Numbers of colonies produced by MM cells transfected with CD229 siRNA or scrambled control siRNA were compared to those of cultures with untreated cells. Asterisks indicate statistically significant differences (*P&lt;0.05). (D) CD229 mRNA expression was analyzed in healthy tissues by qRT-PCR and normalized to the tissue&#39;s respective expression of housekeeping gene GAPDH. (E) Expression of 4 targets suggested for the treatment of MM on CD34+ hematopoietic progenitor cells in the bone marrow of 3 MM patients. Expression was determined by flow cytometry. Red represents an isotype control, blue staining with the target-specific antibody. (F) Expression of CAR targets on peripheral blood lymphocyte subsets obtained from a healthy donor. Expression was determined by flow cytometry. (G) Expression of CAR targets on B lineage cells from the bone marrow of a MM patient with &gt;10% bone marrow plasma cell infiltration. Gating on B cell subsets was performed as previously described. Expression of CAR targets on CD19-CD38+CD138+MM plasma cells from 3 patients with &gt;10% bone marrow plasma cell infiltration as well as human MM cell lines U266 and RPMI8226 was determined by flow cytometry. 
         FIGS.  7 A- 7 L  show the generation and screening of fully human monoclonal antibodies and CARs against CD229. (A) Schema demonstrating the principle of antibody phage display. After incubation of the phage library with immobilized CD229, bound phages are eluted and amplified in  E. coli . Enriched phage undergo repeated selections to provide a pool of CD229-specific antibodies for the generation of CAR constructs. (B) Analysis of monoclonal binders expressed as soluble scFv constructs in BL21 cells by time-resolved fluorescence assay. (C) Schematic representation of the three screening formats used for antibody binding assays.

(F) Comparison of binding of 23 unique clones to CD229 in three antibody formats. (Bottom) Binding of anti-CD229 scFvs expressed in  E. coli  determined by time resolved florescence (TRF) assay. (Middle) Binding of anti-CD229 scFv-Fc antibodies expressed in 293F cells determined by TRF assay. (Top) Binding of anti-CD229 CARs expressed in 293T cells shown as mean fluorescence intensity (MFI) by flow cytometry. (G) Representative sensorgrams of two CD229-specific antibodies, as determined by surface plasmon resonance. (H) Cross-reactivity analysis of 16 CD229 antibodies against all known SLAM family receptors as well as murine CD229, and anti-human Fc as determined by surface plasmon resonance. (I) Expression of CD229 as determined by flow cytometry staining using anti-CD229 scFv clone 2D3 (Panel E, lower left) on untransfected 293 cells or 293 cells transfected with a CD229 expression construct. (J) Expression of CD229 as determined by flow cytometry staining with 2D3 on healthy lymphocyte subsets, T cells activated with CD3/CD28 beads and stimulated with IL-2, as well as MM cell line U266. Far left areas represent isotype control staining, black lines and far right areas represent 2D3 staining. Bottom panels show CD19-CD38+CD138+MM plasma cells from 3 patients with &gt;10% MM plasma cell infiltration. (K) Computational model of the structure of CD229. The bottom left of the four main regions indicates C2-type 2 domain deleted in isoform 3. (L) RT-PCR of CD229 isoforms in lymphocyte subsets and MM cell line U266. 
         FIGS.  8 A- 8 H  show the manufacturing and efficacy of CD229 CAR T cells. (A) Primary human T cells were isolated and activated using CD3/CD28 beads and stimulated every 2 days by addition of 40 U/ml of IL-2. T cells were transduced with lentiviral supernatants encoding a CD19-specific CAR based on scFv clone FMC63 or our CD229-specific CAR based on scFv clone 2D3 on days 2 and 3 and kept at a concentration of 0.4×106 cells/ml until day 12. PD-1 expression on these cells was determined multiple times throughout CAR T cells manufacturing by flow cytometry. (B) CAR T cell expansion during manufacturing. (C) CAR T cell phenotype was evaluated multiple times throughout manufacturing for both CAR T cell populations by flow cytometry. (D) K562 cells transduced with a GFP control construct or a CD229 expression construct were sorted for reporter expression and incubated for 4 h with CD229 CAR T cells. Cytotoxicity was determined by flow cytometry. (E) Human MM cell lines U266 and RPMI8226 were transduced with luciferase and incubated overnight with T cells transduced with GFP or our CD229 CAR construct. Luminescence was determined the next morning after addition of luciferin and cytotoxicity was calculated as the fraction of luminescence signal of untreated target cells. Note: different effector-target ratios were used for the two cell lines. Reduced efficacy compared to panel F of the CART cells used for this experiment may be the result of prolonged expansion for more than 3 weeks. (F) CD19 and CD229 CAR T cells were incubated overnight with U266 cells transduced with a luciferase construct at very low effector-target ratios. Cytotoxicity was determined as described above. (G) Healthy lymphocytes subsets were purified and stained with calcein AM, and T cells activated for multiple days with CD3/CD28 beads and repeatedly stimulated with IL-2 were incubated for 4 h with CD229 CAR T cells. Cytotoxicity was determined by flow cytometry. (H) NSG mice were injected with 5×106 U266 cells expressing luciferase on day 0.5×106 CAR T cells or PBS were injected on day 7 and bioluminescence was determined on day 6, day 13, and day 24. 
         FIG.  9    shows the presence of CD229 as recognized by clone 2D3 on two Burkitt&#39;s lymphoma cell lines. 
     
    
    
     DETAILED DESCRIPTION 
     The disclosed method and compositions may be understood more readily by reference to the following detailed description of particular embodiments and the Example included therein and to the Figures and their previous and following description. 
     It is to be understood that the disclosed method and compositions are not limited to specific synthetic methods, specific analytical techniques, or to particular reagents unless otherwise specified, and, as such, may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. 
     Disclosed are materials, compositions, and components that can be used for, can be used in conjunction with, can be used in preparation for, or are products of the disclosed method and compositions. These and other materials are disclosed herein, and it is understood that when combinations, subsets, interactions, groups, etc. of these materials are disclosed that while specific reference of each various individual and collective combinations and permutation of these compounds may not be explicitly disclosed, each is specifically contemplated and described herein. If a class of molecules A, B, and C are disclosed as well as a class of molecules D, E, and F and an example of a combination molecule, A-D is disclosed, then even if each is not individually recited, each is individually and collectively contemplated. Thus, is this example, each of the combinations A-E, A-F, B-D, B-E, B-F, C-D, C-E, and C-F are specifically contemplated and should be considered disclosed from disclosure of A, B, and C; D, E, and F; and the example combination A-D. Likewise, any subset or combination of these is also specifically contemplated and disclosed. Thus, for example, the sub-group of A-E, B-F, and C-E are specifically contemplated and should be considered disclosed from disclosure of A, B, and C; D, E, and F; and the example combination A-D. This concept applies to all aspects of this application including, but not limited to, steps in methods of making and using the disclosed compositions. Thus, if there are a variety of additional steps that can be performed it is understood that each of these additional steps can be performed with any specific embodiment or combination of embodiments of the disclosed methods, and that each such combination is specifically contemplated and should be considered disclosed. 
     A. Definitions 
     It is understood that the disclosed method and compositions are not limited to the particular methodology, protocols, and reagents described as these may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention which will be limited only by the appended claims. 
     It must be noted that as used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural reference unless the context clearly dictates otherwise. Thus, for example, reference to “a CD229 antigen binding domain” includes a plurality of such binding domains, reference to “the CD229 antigen binding domain” is a reference to one or more CD229 antigen binding domains and equivalents thereof known to those skilled in the art, and so forth. 
     “Optional” or “optionally” means that the subsequently described event, circumstance, or material may or may not occur or be present, and that the description includes instances where the event, circumstance, or material occurs or is present and instances where it does not occur or is not present. 
     Ranges may be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, also specifically contemplated and considered disclosed is the range¬ from the one particular value and/or to the other particular value unless the context specifically indicates otherwise. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another, specifically contemplated embodiment that should be considered disclosed unless the context specifically indicates otherwise. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint unless the context specifically indicates otherwise. Finally, it should be understood that all of the individual values and sub-ranges of values contained within an explicitly disclosed range are also specifically contemplated and should be considered disclosed unless the context specifically indicates otherwise. The foregoing applies regardless of whether in particular cases some or all of these embodiments are explicitly disclosed. 
     Throughout the description and claims of this specification, the word “comprise” and variations of the word, such as “comprising” and “comprises,” means “including but not limited to,” and is not intended to exclude, for example, other additives, components, integers or steps. In particular, in methods stated as comprising one or more steps or operations it is specifically contemplated that each step comprises what is listed (unless that step includes a limiting term such as “consisting of”), meaning that each step is not intended to exclude, for example, other additives, components, integers or steps that are not listed in the step. 
     A “single-chain variable fragment (scFv)” means a protein comprising the variable regions of the heavy and light chains of an antibody. A scFv can be a fusion protein comprising a variable heavy chain, a linker, and a variable light chain. 
     A “fragment antigen-binding fragment (Fab)” is a region of an antibody that binds to antigen. An Fab comprises constant and variable regions from both heavy and light chains. 
     A “CDR” or complementarity determining region is a region of hypervariability interspersed within regions that are more conserved, termed “framework regions” (FR). 
     The term “monoclonal antibody” (monoclonal antibody) refers to an antibody, or population of like antibodies, obtained from a population of substantially homogeneous antibodies, and is not to be construed as requiring production of the antibody by any particular method, including but not limited to, monoclonal antibodies can be made by the hybridoma method first described by Kohler and Milstein (Nature, 256: 495-497, 1975), or by recombinant DNA methods. 
     The term “chimeric antibody” (or “chimeric immunoglobulin”) refers to a molecule comprising a heavy and/or light chain which is identical with or homologous to corresponding sequences in antibodies derived from a particular species or belonging to a particular antibody class or subclass, while the remainder of the chain(s) is identical with or homologous to corresponding sequences in antibodies derived from another species or belonging to another antibody class or subclass, as well as fragments of such antibodies, so long as they exhibit the desired biological activity (Cabilly et al. (1984), infra; Morrison et al., Proc. Natl. Acad. Sci. U.S.A. 81:6851). 
     The term “humanized antibody” refers to forms of antibodies that contain sequences from non-human (eg, murine) antibodies as well as human antibodies. A humanized antibody can include conservative amino acid substitutions or non-natural residues from the same or different species that do not significantly alter its binding and/or biologic activity. Such antibodies are chimeric antibodies that contain minimal sequence derived from non-human immunoglobulins. For the most part, humanized antibodies are human immunoglobulins (recipient antibody) in which residues from a complementary-determining region (CDR) of the recipient are replaced by residues from a CDR of a non-human species (donor antibody) such as mouse, rat, camel, bovine, goat, or rabbit having the desired properties. Furthermore, humanized antibodies can comprise residues that are found neither in the recipient antibody nor in the imported CDR or framework sequences. These modifications are made to further refine and maximize antibody performance. Thus, in general, a humanized antibody can comprise all or substantially all of at least one, and in one aspect two, variable domains, in which all or substantially all of the hypervariable loops correspond to those of a non-human immunoglobulin and all or substantially all of the FR regions are those of a human immunoglobulin sequence. The humanized antibody optionally also can comprise at least a portion of an immunoglobulin constant region (Fc), or that of a human immunoglobulin (see, e.g., Cabilly et al., U.S. Pat. No. 4,816,567; Cabilly et al., European Patent No. 0,125,023 B1; Boss et al., U.S. Pat. No. 4,816,397; Boss et al., European Patent No. 0,120,694 B1; Neuberger, M. S. et al., WO 86/01533; Neuberger, M. S. et al., European Patent No. 0,194,276 B1; Winter, U.S. Pat. No. 5,225,539; Winter, European Patent No. 0,239,400 B1; Padlan, E. A. et al., European Patent Application No. 0,519,596 A1; Queen et al. (1989) Proc. Natl. Acad. Sci. USA, Vol 86:10029-10033). 
     Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of skill in the art to which the disclosed method and compositions belong. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present method and compositions, the particularly useful methods, devices, and materials are as described. Publications cited herein and the material for which they are cited are hereby specifically incorporated by reference. Nothing herein is to be construed as an admission that the present invention is not entitled to antedate such disclosure by virtue of prior invention. No admission is made that any reference constitutes prior art. The discussion of references states what their authors assert, and applicants reserve the right to challenge the accuracy and pertinency of the cited documents. It will be clearly understood that, although a number of publications are referred to herein, such reference does not constitute an admission that any of these documents forms part of the common general knowledge in the art. 
     B. Chimeric Antigen Receptor (CAR) Polypeptide 
     Disclosed are chimeric antigen receptor (CAR) polypeptides comprising a CD229 antigen binding domain, a transmembrane domain, and an intracellular signaling domain. The CD229 antigen binding domain, transmembrane domain, and intracellular signaling domain can be any of those described herein and any combination of those described herein. In some instances, any of the disclosed CAR polypeptides can further comprise a tag sequence. In some instances, the tag sequence can be located between the CD229 antigen binding domain and the transmembrane domain or between the CD229 antigen binding domain and a hinge region. In some instances, the tag sequence can be a hemagglutinin tag, histidine tag, glutathione-S-transferase tag, or fluorescent tag. For example, the tag can be any sequence capable of aiding in the purification of the CAR polypeptide or capable of detecting the CAR polypeptide. 
     1. CD229 Antigen Binding Domain 
     In some instances, the CD229 antigen binding domain can be an antibody fragment or an antigen-binding fragment that specifically binds to CD229. In some instances, the CD229 antigen binding domain can be any recombinant or engineered protein domain capable of binding CD229. 
     In some instances, the CD229 antigen binding domain can be a Fab or a single-chain variable fragment (scFv) of an antibody that specifically binds CD229. In some instances, the scFv, comprising both the heavy chain variable region and the light chain variable region, can comprise the N-terminal region of the heavy chain variable region linked to the C-terminal region of the light chain variable region. In some instances, the scFv comprises the C-terminal region of the heavy chain variable region linked to the N-terminal region of the light chain variable region. 
     In some instances, the CD229 antigen binding domain comprises an amino acid sequence set forth in SEQ ID NO: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15. In some instances, the CD229 antigen binding domain can comprise a heavy chain variable region, a light chain variable region, and a linker that links the heavy chain variable region to the light chain variable region. For example, SEQ ID NOs:1-15 comprise the heavy chain variable region, linker, and light chain variable region (see Table 1). In some instances, the linker can be directly involved in the binding of CD229 to the CD229 antigen binding domain.

     2. Transmembrane Domain 
     In some instances, the transmembrane domain comprises an immunoglobulin Fc domain. In some instances, the immunoglobulin Fc domain can be an immunoglobulin G Fc domain. 
     In some instances, the transmembrane domain comprises a CD8α domain, CD3ζ, FcεR1γ, CD4, CD7, CD28, OX40, or H2-Kb. 
     In some instances, the transmembrane domain can be located between the CD229 antigen binding domain and the intracellular signaling domain. 
     3. Intracellular Signaling Domain 
     In some instances, the intracellular signaling domain comprises a co-stimulatory signaling region. In some instances, the co-stimulatory signaling region can comprise the cytoplasmic domain of a costimulatory molecule selected from the group consisting of CD27, CD28, 4-1BB, OX40, CD30, CD40, PD-1, ICOS, lymphocyte function-associated antigen-1 (LFA-1), CD2, CD7, LIGHT, NKG2C, B7-H3, a ligand that specifically binds with CD83, and any combination thereof. 
     In some instances, the intracellular signaling domain can be a T cell signaling domain. For example, the intracellular signaling domain can comprise a CD3ζ signaling domain. In some instances, CD3ζ signaling domain is the intracellular domain of CD3ζ. 
     In some instances, the intracellular signaling domain comprises a CD3ζ signaling domain and a co-stimulatory signaling region, wherein the co-stimulatory signaling region comprises the cytoplasmic domain of CD28, 4-1BB, CD27, CD28, 4-1BB, OX40, CD30, CD40, PD-1, ICOS, lymphocyte function-associated antigen-1 (LFA-1), CD2, CD7, LIGHT, NKG2C, B7-H3, a ligand that specifically binds with CD83, and any combination thereof 
     4. Hinge Region 
     Any of the disclosed CAR polypeptides can further comprise a hinge region. For example, disclosed are CAR polypeptides comprising a CD229 antigen binding domain, a transmembrane domain, and an intracellular signaling domain and further comprising a hinge region. 
     In some instances, the hinge region can be located between the CD229 antigen binding domain and the transmembrane domain. 
     In some instances, the hinge region allows for the CD229 antigen binding domain to bind to the antigen. For example, the hinge region can increase the distance of the binding domain to the cell surface and provide flexibility. 
     C. CAR Nucleic Acid Sequence

     A CAR-expressing cell described herein may be used in combination with other known agents and therapies. Administered “in combination”, as used herein, means that two (or more) different treatments are delivered to the subject during the course of the subject&#39;s affliction with the disorder, e.g., the two or more treatments are delivered after the subject has been diagnosed with the disorder and before the disorder has been cured or eliminated or treatment has ceased for other reasons. In some embodiments, the delivery of one treatment is still occurring when the delivery of the second begins, so that there is overlap in terms of administration. This is sometimes referred to herein as “simultaneous” or “concurrent delivery”. In other embodiments, the delivery of one treatment ends before the delivery of the other treatment begins. In some embodiments of either case, the treatment is more effective because of combined administration. For example, the second treatment is more effective, e.g., an equivalent effect is seen with less of the second treatment, or the second treatment reduces symptoms to a greater extent, than would be seen if the second treatment were administered in the absence of the first treatment, or the analogous situation is seen with the first treatment. In some embodiments, delivery is such that the reduction in a symptom, or other parameter related to the disorder is greater than what would be observed with one treatment delivered in the absence of the other. The effect of the two treatments can be partially additive, wholly additive, or greater than additive. The delivery can be such that an effect of the first treatment delivered is still detectable when the second is delivered. 
     A CAR-expressing cell described herein and the at least one additional therapeutic agent can be administered simultaneously, in the same or in separate compositions, or sequentially. For sequential administration, the CAR-expressing cell described herein can be administered first, and the additional agent can be administered second, or the order of administration can be reversed. 
     In one embodiment, a first CAR-expressing cell described herein, e.g., a BCMA CAR-expressing cell described herein, may be used in combination with a second CAR-expressing cell. In one embodiment, the second CAR-expressing cell expresses a CAR comprising a different anti-BMCA binding domain, e.g., an anti-BCMA binding domain described herein that differs from the anti-BCMA binding domain in the CAR expressed by the first CAR-expressing cell. In one embodiment, the second CAR-expressing cell expresses a CAR comprising an antigen-binding domain that targets an antigen other than BCMA (e.g., CD19, CD20, CS-1, kappa light chain, CD139, Lewis Y antigen, or CD38). In one embodiment, a first CAR-expressing cell described herein, e.g., a BCMA CAR-expressing cell described herein, is used in combination with a second CAR-expressing cell comprising a CD19 CAR. In one embodiment, a BCMA CAR-expressing cell described herein is used in combination with a CD19 CAR-expressing cell to treat a BCMA-associated cancer described herein, e.g., multiple myeloma. In some embodiments, the multiple myeloma is CD19-negative, e.g., having a vast majority (e.g., at least 98%, 99%, 99.5%, 99.9%, or 99.95%) of the neoplastic plasma cells with a CD19-negative phenotype, e.g., as detected flow cytometry, RT-PCR, or both flow cytometry and RT-PCR. As shown in Example 17 herein, a CD19 CAR can be effective even against a CD19-negative multiple myeloma. While not wishing to be bound by theory, the CD19 CAR may act on a small but important CD19-positive population of neoplastic cells, by targeting a cell that expresses levels of CD19 that fall below the detection threshold of the assays described herein, or by targeting a non-neoplastic cell that supports the neoplastic cells. In embodiments, a CD19 CAR can remove B cells, e.g., B regulatory B cells. 
     For example, in one embodiment, the first CAR-expressing cell described herein, e.g., a BCMA CAR-expressing cell, and the second CAR-expressing cell described herein, e.g., a CD19 CAR-expressing cell, are prepared in the same composition and are administered simultaneously. In another embodiment, the first CAR-expressing cell described herein, e.g., a BCMA CAR-expressing cell, and the second CAR-expressing cell described herein, e.g., a CD19 CAR-expressing cell, are prepared in separate compositions, and the separate compositions are administered simultaneously or sequentially. When the BCMA CAR-expressing cell and the second CAR-expressing cell are prepared in separate compositions, the BCMA CAR-expressing cell can be administered first, and the second CAR-expressing cell can be administered second, or the order of administration can be reversed. 
     In one embodiment, a CD19 CAR is a CD19 CAR, e.g., a humanized CD19 CAR, described in WO2014/153270, filed Mar. 15, 2014 (which is incorporated by reference herein in its entirety) or a sequence at least 95%, e.g., 95-99%, identical thereto. In some embodiments, the CD19 CAR construct is a CAR19 construct provided in PCT publication WO2012/079000 (which is incorporated by reference herein in its entirety) or a sequence at least 95%, e.g., 95-99%, identical thereto. In one embodiment, the anti-CD19 binding domain is a scFv described in WO2012/079000, or a sequence at least 95%, e.g., 95-99%, identical thereto. 
     In embodiments, a first CAR-expressing cell is administered to a subject, and a second CAR-expressing cell is administered to the subject. In embodiments, the first CAR-expressing cell comprises a CAR (e.g., BCMA or CD19 CAR) comprising a CD27 costimulatory domain and a CD3zeta (mutant or wild type) primary signaling domain. In embodiments, the second CAR-expressing cell comprises a CAR (e.g., BCMA CAR) comprising a 4-1BB costimulatory domain and a CD3zeta (mutant or wild type) primary signaling domain. Without wishing to be bound by theory, in embodiments, the first CAR-expressing cell can be less toxic than the second CAR-expressing cell and be used to debulk a tumor.

In an embodiment, the subject has MCL. MCL is an aggressive cancer that is poorly responsive to currently available therapies, i.e., essentially incurable. In many cases of MCL, cyclin D1 (a regulator of CDK4/6) is expressed (e.g., due to chromosomal translocation involving immunoglobulin and Cyclin D1 genes) in MCL cells. Thus, without being bound by theory, it is thought that MCL cells are highly sensitive to CDK4/6 inhibition with high specificity (i.e., minimal effect on normal immune cells). CDK4/6 inhibitors alone have had some efficacy in treating MCL, but have only achieved partial remission with a high relapse rate. An exemplary CDK4/6 inhibitor is LEE011 (also called ribociclib), the structure of which is shown below. 
     
       
         
         
             
             
         
       
     
     Without being bound by theory, it is believed that administration of a CAR-expressing cell described herein with a CDK4/6 inhibitor (e.g., LEE011 or other CDK4/6 inhibitor described herein) can achieve higher responsiveness, e.g., with higher remission rates and/or lower relapse rates, e.g., compared to a CDK4/6 inhibitor alone. 
     In one embodiment, the kinase inhibitor is a BTK inhibitor selected from ibrutinib (PCI-32765); GDC-0834; RN-486; CGI-560; CGI-1764; HM-71224; CC-292; ONO-4059; CNX-774; and LFM-A13. In a preferred embodiment, the BTK inhibitor does not reduce or inhibit the kinase activity of interleukin-2-inducible kinase (ITK), and is selected from GDC-0834; RN-486; CGI-560; CGI-1764; HM-71224; CC-292; ONO-4059; CNX-774; and LFM-A13. 
     In one embodiment, the kinase inhibitor is a BTK inhibitor, e.g., ibrutinib (PCI-32765). In embodiments, a CAR-expressing cell described herein is administered to a subject in combination with a BTK inhibitor (e.g., ibrutinib). In embodiments, a CAR-expressing cell described herein is administered to a subject in combination with ibrutinib (also called PCI-32765). The structure of ibrutinib (1-[(3R)-3-[4-Amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]piperidin-1-yl]prop-2-en-1-one) is shown below. 
     
       
         
         
             
             
         
       
     
     In embodiments, the subject has CLL, mantle cell lymphoma (MCL), or small lymphocytic lymphoma (SLL). For example, the subject has a deletion in the short arm of chromosome 17 (del(17p), e.g., in a leukemic cell). In other examples, the subject does not have a del(17p). In embodiments, the subject has relapsed CLL or SLL, e.g., the subject has previously been administered a cancer therapy (e.g., previously been administered one, two, three, or four prior cancer therapies). In embodiments, the subject has refractory CLL or SLL. In other embodiments, the subject has follicular lymphoma, e.g., relapse or refractory follicular lymphoma. In some embodiments, ibrutinib is administered at a dosage of about 300-600 mg/day (e.g., about 300-350, 350-400, 400-450, 450-500, 500-550, or 550-600 mg/day, e.g., about 420 mg/day or about 560 mg/day), e.g., orally. In embodiments, the ibrutinib is administered at a dose of about 250 mg, 300 mg, 350 mg, 400 mg, 420 mg, 440 mg, 460 mg, 480 mg, 500 mg, 520 mg, 540 mg, 560 mg, 580 mg, 600 mg (e.g., 250 mg, 420 mg or 560 mg) daily for a period of time, e.g., daily for 21 day cycle cycle, or daily for 28 day cycle. In one embodiment, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 or more cycles of ibrutinib are administered. In some embodiments, ibrutinib is administered in combination with rituximab. See, e.g., Burger et al. (2013) Ibrutinib In Combination With Rituximab (iR) Is Well Tolerated and Induces a High Rate Of Durable Remissions In Patients With High-Risk Chronic Lymphocytic Leukemia (CLL): New, Updated Results Of a Phase II Trial In 40 Patients, Abstract 675 presented at 55th ASH Annual Meeting and Exposition, New Orleans, La. 7-10 December Without being bound by theory, it is thought that the addition of ibrutinib enhances the T cell proliferative response and may shift T cells from a T-helper-2 (Th2) to T-helper-1 (Th1) phenotype. Th1 and Th2 are phenotypes of helper T cells, with Th1 versus Th2 directing different immune response pathways. A Th1 phenotype is associated with proinflammatory responses, e.g., for killing cells, such as intracellular pathogens/viruses or cancerous cells, or perpetuating autoimmune responses. A Th2 phenotype is associated with eosinophil accumulation and anti-inflammatory responses.

     In embodiments, a CAR-expressing cell described herein is administered to a subject in combination with an indoleamine 2,3-dioxygenase (IDO) inhibitor. IDO is an enzyme that catalyzes the degradation of the amino acid, L-tryptophan, to kynurenine. Many cancers overexpress IDO, e.g., prostatic, colorectal, pancreatic, cervical, gastric, ovarian, head, and lung cancer. pDCs, macrophages, and dendritic cells (DCs) can express IDO. Without being bound by theory, it is thought that a decrease in L-tryptophan (e.g., catalyzed by IDO) results in an immunosuppressive milieu by inducing T-cell anergy and apoptosis. Thus, without being bound by theory, it is thought that an IDO inhibitor can enhance the efficacy of a CAR-expressing cell described herein, e.g., by decreasing the suppression or death of a CAR-expressing immune cell. In embodiments, the subject has a solid tumor, e.g., a solid tumor described herein, e.g., prostatic, colorectal, pancreatic, cervical, gastric, ovarian, head, or lung cancer. Exemplary inhibitors of IDO include but are not limited to 1-methyl-tryptophan, indoximod (NewLink Genetics) (see, e.g., Clinical Trial Identifier Nos. NCT01191216; NCT01792050), and INCB024360 (Incyte Corp.) (see, e.g., Clinical Trial Identifier Nos. NCT01604889; NCT01685255) 
     In embodiments, a CAR-expressing cell described herein is administered to a subject in combination with a modulator of myeloid-derived suppressor cells (MDSCs). MDSCs accumulate in the periphery and at the tumor site of many solid tumors. These cells suppress T cell responses, thereby hindering the efficacy of CAR-expressing cell therapy. Without being bound by theory, it is thought that administration of a MDSC modulator enhances the efficacy of a CAR-expressing cell described herein. In an embodiment, the subject has a solid tumor, e.g., a solid tumor described herein, e.g., glioblastoma. Exemplary modulators of MDSCs include but are not limited to MCS110 and BLZ945. MCS110 is a monoclonal antibody (mAb) against macrophage colony-stimulating factor (M-CSF). See, e.g., Clinical Trial Identifier No. NCT00757757. BLZ945 is a small molecule inhibitor of colony stimulating factor 1 receptor (CSF1R). See, e.g., Pyonteck et al. Nat. Med. 19 (2013):1264-72. The structure of BLZ945 is shown below. 
     
       
         
         
             
             
         
       
     
     In embodiments, a CAR-expressing cell described herein is administered to a subject in combination with a CD19 CART cell (e.g., CTL019, e.g., as described in WO2012/079000, incorporated herein by reference). In embodiments, the subject has acute myeloid leukemia (AML), e.g., a CD19 positive AML or a CD19 negative AML. In embodiments, the subject has a CD19+ lymphoma, e.g., a CD19+Non-Hodgkin&#39;s Lymphoma (NHL), a CD19+FL, or a CD19+DLBCL. In embodiments, the subject has a relapsed or refractory CD19+ lymphoma. In embodiments, a lymphodepleting chemotherapy is administered to the subject prior to, concurrently with, or after administration (e.g., infusion) of CD19 CART cells. In an example, the lymphodepleting chemotherapy is administered to the subject prior to administration of CD19 CART cells. For example, the lymphodepleting chemotherapy ends 1-4 days (e.g., 1, 2, 3, or 4 days) prior to CD19 CART cell infusion. In embodiments, multiple doses of CD19 CART cells are administered, e.g., as described herein. For example, a single dose comprises about 5×108 CD19 CART cells. In embodiments, a lymphodepleting chemotherapy is administered to the subject prior to, concurrently with, or after administration (e.g., infusion) of a CAR-expressing cell described herein, e.g., a non-CD19 CAR-expressing cell. In embodiments, a CD19 CART is administered to the subject prior to, concurrently with, or after administration (e.g., infusion) of a non-CD19 CAR-expressing cell, e.g., a non-CD19 CAR-expressing cell described herein. 
     In some embodiments, a CAR-expressing cell described herein is administered to a subject in combination with a CD19 CAR-expressing cell, e.g., CTL019, e.g., as described in WO2012/079000, incorporated herein by reference, for treatment of a disease associated with the expression of BCMA, e.g., a cancer described herein. Without being bound by theory, it is believed that administering a CD19 CAR-expressing cell in combination with a CAR-expressing cell improves the efficacy of a CAR-expressing cell described herein by targeting early lineage cancer cells, e.g., cancer stem cells, modulating the immune response, depleting regulatory B cells, and/or improving the tumor microenvironment. For example, a CD19 CAR-expressing cell targets cancer cells that express early lineage markers, e.g., cancer stem cells and CD19-expressing cells, while the CAR-expressing cell described herein targets cancer cells that express later lineage markers, e.g., BCMA. This preconditioning approach can improve the efficacy of the CAR-expressing cell described herein. In such embodiments, the CD19 CAR-expressing cell is administered prior to, concurrently with, or after administration (e.g., infusion) of a CAR-expressing cell described herein. 
     In embodiments, a CAR-expressing cell described herein also expresses a CAR targeting CD19, e.g., a CD19 CAR. In an embodiment, the cell expressing a CAR described herein and a CD19 CAR is administered to a subject for treatment of a cancer described herein, e.g., AML. In an embodiment, the configurations of one or both of the CAR molecules comprise a primary intracellular signaling domain and a costimulatory signaling domain. In another embodiment, the configurations of one or both of the CAR molecules comprise a primary intracellular signaling domain and two or more, e.g., 2, 3, 4, or 5 or more, costimulatory signaling domains. In such embodiments, the CAR molecule described herein and the CD19 CAR may have the same or a different primary intracellular signaling domain, the same or different costimulatory signaling domains, or the same number or a different number of costimulatory signaling domains. Alternatively, the CAR described herein and the CD19 CAR are configured as a split CAR, in which one of the CAR molecules comprises an antigen binding domain and a costimulatory domain (e.g., 4-1BB), while the other CAR molecule comprises an antigen binding domain and a primary intracellular signaling domain (e.g., CD3 zeta). 
     In some embodiments, a CAR-expressing cell described herein is administered to a subject in combination with a interleukin-15 (IL-15) polypeptide, a interleukin-15 receptor alpha (IL-15Ra) polypeptide, or a combination of both a IL-15 polypeptide and a IL-15Ra polypeptide e.g., hetIL-15 (Admune Therapeutics, LLC). hetIL-15 is a heterodimeric non-covalent complex of IL-15 and IL-15Ra. hetIL-15 is described in, e.g., U.S. Pat. No. 8,124,084, U.S. 2012/0177598, U.S. 2009/0082299, U.S. 2012/0141413, and U.S. 2011/0081311, incorporated herein by reference. In embodiments, het-IL-15 is administered subcutaneously. In embodiments, the subject has a cancer, e.g., solid cancer, e.g., melanoma or colon cancer. In embodiments, the subject has a metastatic cancer. 
     In one embodiment, the subject can be administered an agent which reduces or ameliorates a side effect associated with the administration of a CAR-expressing cell. Side effects associated with the administration of a CAR-expressing cell include, but are not limited to CRS, and hemophagocytic lymphohistiocytosis (HLH), also termed Macrophage Activation Syndrome (MAS). Symptoms of CRS include high fevers, nausea, transient hypotension, hypoxia, and the like. CRS may include clinical constitutional signs and symptoms such as fever, fatigue, anorexia, myalgias, arthalgias, nausea, vomiting, and headache. CRS may include clinical skin signs and symptoms such as rash. CRS may include clinical gastrointestinal signs and symptoms such as nausea, vomiting and diarrhea. CRS may include clinical respiratory signs and symptoms such as tachypnea and hypoxemia. CRS may include clinical cardiovascular signs and symptoms such as tachycardia, widened pulse pressure, hypotension, increased cardiac output (early) and potentially diminished cardiac output (late). CRS may include clinical coagulation signs and symptoms such as elevated d-dimer, hypofibrinogenemia with or without bleeding. CRS may include clinical renal signs and symptoms such as azotemia. CRS may include clinical hepatic signs and symptoms such as transaminitis and hyperbilirubinemia. CRS may include clinical neurologic signs and symptoms such as headache, mental status changes, confusion, delirium, word finding difficulty or frank aphasia, hallucinations, tremor, dymetria, altered gait, and seizures. 
     Accordingly, the methods described herein can comprise administering a CAR-expressing cell described herein to a subject and further administering one or more agents to manage elevated levels of a soluble factor resulting from treatment with a CAR-expressing cell. In one embodiment, the soluble factor elevated in the subject is one or more of IFN-γ, TNFα, IL-2 and IL-6. In an embodiment, the factor elevated in the subject is one or more of IL-1, GM-CSF, IL-10, IL-8, IL-5 and fraktalkine. Therefore, an agent administered to treat this side effect can be an agent that neutralizes one or more of these soluble factors. In one embodiment, the agent that neutralizes one or more of these soluble forms is an antibody or antibody fragment. Examples of such agents include, but are not limited to a steroid (e.g., corticosteroid), an inhibitor of TNFα, and an inhibitor of IL-6. An example of a TNFα inhibitor is an anti-TNFα antibody molecule such as, infliximab, adalimumab, certolizumab pegol, and golimumab. Another example of a TNFα inhibitor is a fusion protein such as entanercept. Small molecule inhibitors of TNFα include, but are not limited to, xanthine derivatives (e.g. pentoxifylline) and bupropion. An example of an IL-6 inhibitor is an anti-IL-6 antibody molecule such as tocilizumab (toc), sarilumab, elsilimomab, CNTO 328, ALD518/BMS-945429, CNTO 136, CPSI-2364, CDP6038, VX30, ARGX-109, FE301, and FM101. In one embodiment, the anti-IL-6 antibody molecule is tocilizumab. An example of an IL-1R based inhibitor is anakinra. 
     In some embodiment, the subject is administered a corticosteroid, such as, e.g., methylprednisolone, hydrocortisone, among others. 
     In some embodiments, the subject is administered a vasopressor, such as, e.g., norepinephrine, dopamine, phenylephrine, epinephrine, vasopressin, or a combination thereof. 
     In an embodiment, the subject can be administered an antipyretic agent. In an embodiment, the subject can be administered an analgesic agent. 
     In one embodiment, the subject can be administered an agent which enhances the activity of a CAR-expressing cell. For example, in one embodiment, the agent can be an agent which inhibits an inhibitory molecule, e.g., the agent is a checkpoint inhibitor. Inhibitory molecules, e.g., Programmed Death 1 (PD1), can, in some embodiments, decrease the ability of a CAR-expressing cell to mount an immune effector response. Examples of inhibitory molecules include PD1, PD-L1, PD-L2, CTLA4, TIM3, CEACAM (e.g., CEACAM-1, CEACAM-3 and/or CEACAM-5), LAG3, VISTA, BTLA, TIGIT, LAIR1, CD160, 2B4, CD80, CD86, B7-H3 (CD276), B7-H4 (VTCN1), HVEM (TNFRSF14 or CD270), KIR, A2aR, MHC class I, MHC class II, GALS, adenosine, and TGFR beta. Inhibition of an inhibitory molecule, e.g., by inhibition at the DNA, RNA or protein level, can optimize a CAR-expressing cell performance. In embodiments, an inhibitory nucleic acid, e.g., an inhibitory nucleic acid, e.g., a dsRNA, e.g., an siRNA or shRNA, a clustered regularly interspaced short palindromic repeats (CRISPR), a transcription-activator like effector nuclease (TALEN), or a zinc finger endonuclease (ZFN), e.g., as described herein, can be used to inhibit expression of an inhibitory molecule in the CAR-expressing cell. In an embodiment the inhibitor is an shRNA. In an embodiment, the inhibitory molecule is inhibited within a CAR-expressing cell. In these embodiments, a dsRNA molecule that inhibits expression of the inhibitory molecule is linked to the nucleic acid that encodes a component, e.g., all of the components, of the CAR. In embodiments, a CAR-expressing cell described herein is administered in combination with an inhibitor of an inhibitory molecule, e.g., in combination with a checkpoint inhibitor, e.g., in combination with an inhibitor of PD1 and/or PD-L1. In embodiments, a CAR-expressing cell described herein is administered in combination with an inhibitor of PD1. In embodiments, a CAR-expressing cell described herein is administered in combination with an inhibitor of PD-L1. 
     In an embodiment, a nucleic acid molecule that encodes a dsRNA molecule that inhibits expression of the molecule that modulates or regulates, e.g., inhibits, T-cell function is operably linked to a promoter, e.g., a H1- or a U6-derived promoter such that the dsRNA molecule that inhibits expression of the molecule that modulates or regulates, e.g., inhibits, T-cell function is expressed, e.g., is expressed within a CAR-expressing cell. See e.g., Tiscornia G., “Development of Lentiviral Vectors Expressing siRNA,” Chapter 3, in Gene Transfer: Delivery and Expression of DNA and RNA (eds. Friedmann and Rossi). Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., USA, 2007; Brummelkamp T R, et al. (2002) Science 296: 550-553; Miyagishi M, et al. (2002) Nat. Biotechnol. 19: 497-500. In an embodiment the nucleic acid molecule that encodes a dsRNA molecule that inhibits expression of the molecule that modulates or regulates, e.g., inhibits, T-cell function is present on the same vector, e.g., a lentiviral vector, that comprises a nucleic acid molecule that encodes a component, e.g., all of the components, of the CAR. In such an embodiment, the nucleic acid molecule that encodes a dsRNA molecule that inhibits expression of the molecule that modulates or regulates, e.g., inhibits, T-cell function is located on the vector, e.g., the lentiviral vector, 5′- or 3′- to the nucleic acid that encodes a component, e.g., all of the components, of the CAR. The nucleic acid molecule that encodes a dsRNA molecule that inhibits expression of the molecule that modulates or regulates, e.g., inhibits, T-cell function can be transcribed in the same or different direction as the nucleic acid that encodes a component, e.g., all of the components, of the CAR. In an embodiment the nucleic acid molecule that encodes a dsRNA molecule that inhibits expression of the molecule that modulates or regulates, e.g., inhibits, T-cell function is present on a vector other than the vector that comprises a nucleic acid molecule that encodes a component, e.g., all of the components, of the CAR. In an embodiment, the nucleic acid molecule that encodes a dsRNA molecule that inhibits expression of the molecule that modulates or regulates, e.g., inhibits, T-cell function it transiently expressed within a CAR-expressing cell. In an embodiment, the nucleic acid molecule that encodes a dsRNA molecule that inhibits expression of the molecule that modulates or regulates, e.g., inhibits, T-cell function is stably integrated into the genome of a CAR-expressing cell.  FIGS.  41 A- 41 E  depicts examples of vectors for expressing a component, e.g., all of the components, of the CAR with a dsRNA molecule that inhibits expression of the molecule that modulates or regulates, e.g., inhibits, T-cell function. 
     dsRNA molecules can be useful for inhibiting expression of a molecule that modulates or regulates, e.g., inhibits, T-cell function, wherein the molecule that modulates or regulates, e.g., inhibits, T-cell function is PD-1. 
     In one embodiment, the inhibitor of an inhibitory signal can be, e.g., an antibody or antibody fragment that binds to an inhibitory molecule. For example, the agent can be an antibody or antibody fragment that binds to PD1, PD-L1, PD-L2 or CTLA4 (e.g., ipilimumab (also referred to as MDX-010 and MDX-101, and marketed as Yervoy®; Bristol-Myers Squibb; Tremelimumab (IgG2 monoclonal antibody available from Pfizer, formerly known as ticilimumab, CP-675,206).). In an embodiment, the agent is an antibody or antibody fragment that binds to TIM3. In an embodiment, the agent is an antibody or antibody fragment that binds to LAG3. In embodiments, the agent that enhances the activity of a CAR-expressing cell, e.g., inhibitor of an inhibitory molecule, is administered in combination with an allogeneic CAR, e.g., an allogeneic CAR described herein (e.g., described in the Allogeneic CAR section herein). 
     PD-1 is an inhibitory member of the CD28 family of receptors that also includes CD28, CTLA-4, ICOS, and BTLA. PD-1 is expressed on activated B cells, T cells and myeloid cells (Agata et al. 1996 Int. Immunol 8:765-75). Two ligands for PD-1, PD-L1 and PD-L2 have been shown to downregulate T cell activation upon binding to PD-1 (Freeman et a. 2000 J Exp Med 192:1027-34; Latchman et al. 2001 Nat Immunol 2:261-8; Carter et al. 2002 Eur J Immunol 32:634-43). PD-L1 is abundant in human cancers (Dong et al. 2003 J Mol Med 81:281-7; Blank et al. 2005 Cancer Immunol. Immunother 54:307-314; Konishi et al. 2004 Clin Cancer Res 10:5094). Immune suppression can be reversed by inhibiting the local interaction of PD-1 with PD-L1. Antibodies, antibody fragments, and other inhibitors of PD-1, PD-L1 and PD-L2 are available in the art and may be used combination with a cars of the present invention described herein. For example, nivolumab (also referred to as BMS-936558 or MDX1106; Bristol-Myers Squibb) is a fully human IgG4 monoclonal antibody which specifically blocks PD-1. Nivolumab (clone 5C4) and other human monoclonal antibodies that specifically bind to PD-1 are disclosed in U.S. Pat. No. 8,008,449 and WO2006/121168. Pidilizumab (CT-011; Cure Tech) is a humanized IgG1k monoclonal antibody that binds to PD-1. Pidilizumab and other humanized anti-PD-1 monoclonal antibodies are disclosed in WO2009/101611. Pembrolizumab (formerly known as lambrolizumab, and also referred to as MK03475; Merck) is a humanized IgG4 monoclonal antibody that binds to PD-1. Pembrolizumab and other humanized anti-PD-1 antibodies are disclosed in U.S. Pat. No. 8,354,509 and WO2009/114335. MEDI4736 (Medimmune) is a human monoclonal antibody that binds to PDL1, and inhibits interaction of the ligand with PD1. MDPL3280A (Genentech/Roche) is a human Fc optimized IgG1 monoclonal antibody that binds to PD-L1. MDPL3280A and other human monoclonal antibodies to PD-L1 are disclosed in U.S. Pat. No. 7,943,743 and U.S Publication No.: 20120039906. Other anti-PD-L1 binding agents include YW243.55.570 (heavy and light chain variable regions are shown in SEQ ID NOs 20 and 21 in WO2010/077634) and MDX-1 105 (also referred to as BMS-936559, and, e.g., anti-PD-L1 binding agents disclosed in WO2007/005874). AMP-224 (B7-DCIg; Amplimmune; e.g., disclosed in WO2010/027827 and WO2011/066342), is a PD-L2 Fc fusion soluble receptor that blocks the interaction between PD-1 and B7-H1. Other anti-PD-1 antibodies include AMP 514 (Amplimmune), among others, e.g., anti-PD-1 antibodies disclosed in U.S. Pat. No. 8,609,089, US 2010028330, and/or US 20120114649. TIM3 (T cell immunoglobulin-3) also negatively regulates T cell function, particularly in IFN-g-secreting CD4+T helper 1 and CD8+T cytotoxic 1 cells, and plays a critical role in T cell exhaustion. Inhibition of the interaction between TIM3 and its ligands, e.g., galectin-9 (Gal9), phosphotidylserine (PS), and HMGB1, can increase immune response. Antibodies, antibody fragments, and other inhibitors of TIM3 and its ligands are available in the art and may be used combination with a CD19 or BCMA CAR described herein. For example, antibodies, antibody fragments, small molecules, or peptide inhibitors that target TIM3 binds to the IgV domain of TIM3 to inhibit interaction with its ligands. Antibodies and peptides that inhibit TIM3 are disclosed in WO2013/006490 and US20100247521. Other anti-TIM3 antibodies include humanized versions of RMT3-23 (disclosed in Ngiow et al., 2011, Cancer Res, 71:3540-3551), and clone 8B.2C12 (disclosed in Monney et al., 2002, Nature, 415:536-541). Bi-specific antibodies that inhibit TIM3 and PD-1 are disclosed in US20130156774. 
     In other embodiments, the agent which enhances the activity of a CAR-expressing cell is a CEACAM inhibitor (e.g., CEACAM-1, CEACAM-3, and/or CEACAM-5 inhibitor). In one embodiment, the inhibitor of CEACAM is an anti-CEACAM antibody molecule. Exemplary anti-CEACAM-1 antibodies are described in WO 2010/125571, WO 2013/082366 WO 2014/059251 and WO 2014/022332, e.g., a monoclonal antibody 34B1, 26H7, and 5F4; or a recombinant form thereof, as described in, e.g., US 2004/0047858, U.S. Pat. No. 7,132,255 and WO 99/052552. In other embodiments, the anti-CEACAM antibody binds to CEACAM-5 as described in, e.g., Zheng et al. PLoS One. 2010 Sep. 2; 5(9). pii: e12529 (DOI: 10:1371/journal.pone.0021146), or crossreacts with CEACAM-1 and CEACAM-5 as described in, e.g., WO 2013/054331 and US 2014/0271618. 
     Without wishing to be bound by theory, carcinoembryonic antigen cell adhesion molecules (CEACAM), such as CEACAM-1 and CEACAM-5, are believed to mediate, at least in part, inhibition of an anti-tumor immune response (see e.g., Markel et al. J Immunol. 2002 Mar. 15; 168(6):2803-10; Markel et al. J Immunol. 2006 Nov. 1; 177(9):6062-71; Markel et al. Immunology. 2009 February; 126(2):186-200; Markel et al. Cancer Immunol Immunother. 2010 February; 59(2):215-30; Ortenberg et al. Mol Cancer Ther. 2012 June; 11(6):1300-10; Stern et al. J Immunol. 2005 Jun. 1; 174(11):6692-701; Zheng et al. PLoS One. 2010 Sep. 2; 5(9). pii: e12529). For example, CEACAM-1 has been described as a heterophilic ligand for TIM-3 and as playing a role in TIM-3-mediated T cell tolerance and exhaustion (see e.g., WO 2014/022332; Huang, et al. (2014) Nature doi:10.1038/nature13848). In embodiments, co-blockade of CEACAM-1 and TIM-3 has been shown to enhance an anti-tumor immune response in xenograft colorectal cancer models (see e.g., WO 2014/022332; Huang, et al. (2014), supra). In other embodiments, co-blockade of CEACAM-1 and PD-1 reduce T cell tolerance as described, e.g., in WO 2014/059251. Thus, CEACAM inhibitors can be used with the other immunomodulators described herein (e.g., anti-PD-1 and/or anti-TIM-3 inhibitors) to enhance an immune response against a cancer, e.g., a melanoma, a lung cancer (e.g., NSCLC), a bladder cancer, a colon cancer an ovarian cancer, and other cancers as described herein. 
     LAG3 (lymphocyte activation gene-3 or CD223) is a cell surface molecule expressed on activated T cells and B cells that has been shown to play a role in CD8+ T cell exhaustion. Antibodies, antibody fragments, and other inhibitors of LAG3 and its ligands are available in the art and may be used combination with a CD19 or BCMA CAR described herein. For example, BMS-986016 (Bristol-Myers Squib) is a monoclonal antibody that targets LAW. IMP701 (Immutep) is an antagonist LAG3 antibody and IMP731 (Immutep and GlaxoSmithKline) is a depleting LAG3 antibody. Other LAG3 inhibitors include IMP321 (Immutep), which is a recombinant fusion protein of a soluble portion of LAG3 and Ig that binds to MHC class II molecules and activates antigen presenting cells (APC). Other antibodies are disclosed, e.g., in WO2010/019570. 
     In some embodiments, the agent which enhances the activity of a CAR-expressing cell can be, e.g., a fusion protein comprising a first domain and a second domain, wherein the first domain is an inhibitory molecule, or fragment thereof, and the second domain is a polypeptide that is associated with a positive signal, e.g., a polypeptide comprising an antracellular signaling domain as described herein. In some embodiments, the polypeptide that is associated with a positive signal can include a costimulatory domain of CD28, CD27, ICOS, e.g., an intracellular signaling domain of CD28, CD27 and/or ICOS, and/or a primary signaling domain, e.g., of CD3 zeta, e.g., described herein. In one embodiment, the fusion protein is expressed by the same cell that expressed the CAR. In another embodiment, the fusion protein is expressed by a cell, e.g., a T cell or NK cell that does not express an anti-BCMA CAR. 
     In one embodiment, the agent which enhances activity of a CAR-expressing cell described herein is miR-17-92. 
     In one embodiment, the agent which enhances activity of a CAR-described herein is a cytokine. Cytokines have important functions related to T cell expansion, differentiation, survival, and homeostatis. Cytokines that can be administered to the subject receiving a CAR-expressing cell described herein include: IL-2, IL-4, IL-7, IL-9, IL-15, IL-18, and IL-21, or a combination thereof. In preferred embodiments, the cytokine administered is IL-7, IL-15, or IL-21, or a combination thereof. The cytokine can be administered once a day or more than once a day, e.g., twice a day, three times a day, or four times a day. The cytokine can be administered for more than one day, e.g. the cytokine is administered for 2 days, 3 days, 4 days, 5 days, 6 days, 1 week, 2 weeks, 3 weeks, or 4 weeks. For example, the cytokine is administered once a day for 7 days. 
     In embodiments, the cytokine is administered in combination with CAR-expressing T cells. The cytokine can be administered simultaneously or concurrently with the CAR-expressing T cells, e.g., administered on the same day. The cytokine may be prepared in the same pharmaceutical composition as the CAR-expressing T cells, or may be prepared in a separate pharmaceutical composition. Alternatively, the cytokine can be administered shortly after administration of the CAR-expressing T cells, e.g., 1 day, 2 days, 3 days, 4 days, 5 days, 6 days, or 7 days after administration of the CAR-expressing T cells. In embodiments where the cytokine is administered in a dosing regimen that occurs over more than one day, the first day of the cytokine dosing regimen can be on the same day as administration with the CAR-expressing T cells, or the first day of the cytokine dosing regimen can be 1 day, 2 days, 3 days, 4 days, 5 days, 6 days, or 7 days after administration of the CAR-expressing T cells. In one embodiment, on the first day, the CAR-expressing T cells are administered to the subject, and on the second day, a cytokine is administered once a day for the next 7 days. In a preferred embodiment, the cytokine to be administered in combination with CAR-expressing T cells is IL-7, IL-15, or IL-21. 
     In other embodiments, the cytokine is administered a period of time after administration of CAR-expressing cells, e.g., at least 2 weeks, 3 weeks, 4 weeks, 6 weeks, 8 weeks, 10 weeks, 12 weeks, 4 months, 5 months, 6 months, 7 months, 8 months, 9 months, 10 months, 11 months, or 1 year or more after administration of CAR-expressing cells. In one embodiment, the cytokine is administered after assessment of the subject&#39;s response to the CAR-expressing cells. For example, the subject is administered CAR-expressing cells according to the dosage and regimens described herein. The response of the subject to CAR-expressing cell therapy is assessed at 2 weeks, 3 weeks, 4 weeks, 6 weeks, 8 weeks, 10 weeks, 12 weeks, 4 months, 5 months, 6 months, 7 months, 8 months, 9 months, 10 months, 11 months, or 1 year or more after administration of CAR-expressing cells, using any of the methods described herein, including inhibition of tumor growth, reduction of circulating tumor cells, or tumor regression. Subjects that do not exhibit a sufficient response to CAR-expressing cell therapy can be administered a cytokine. Administration of the cytokine to the subject that has sub-optimal response to the CAR-expressing cell therapy improves CAR-expressing cell efficacy or anti-cancer activity. In a preferred embodiment, the cytokine administered after administration of CAR-expressing cells is IL-7. 
     Combination with a Low, Immune Enhancing, Dose of an mTOR Inhibitor 
     Methods described herein use low, immune enhancing, doses of mTOR inhibitors, e.g., allosteric mTOR inhibitors, including rapalogs such as RAD001. Administration of a low, immune enhancing, dose of an mTOR inhibitor (e.g., a dose that is insufficient to completely suppress the immune system, but sufficient to improve immune function) can optimize the performance of immune effector cells, e.g., T cells or CAR-expressing cells, in the subject. Methods for measuring mTOR inhibition, dosages, treatment regimens, and suitable pharmaceutical compositions are described in U.S. Patent Application No. 2015/01240036, hereby incorporated by reference. 
     In an embodiment, administration of a low, immune enhancing, dose of an mTOR inhibitor results in one or more of the following: i) a decrease in the number of PD-1 positive immune effector cells; ii) an increase in the number of PD-1 negative immune effector cells; iii) an increase in the ratio of PD-1 negative immune effector cells/PD-1 positive immune effector cells; iv) an increase in the number of naive T cells; v) an increase in the expression of one or more of the following markers: CD62Lhigh, CD127high, CD27+, and BCL2, e.g., on memory T cells, e.g., memory T cell precursors; vi) a decrease in the expression of KLRG1, e.g., on memory T cells, e.g., memory T cell precursors; or vii) an increase in the number of memory T cell precursors, e.g., cells with any one or combination of the following characteristics: increased CD62Lhigh increased CD127high increased CD27+, decreased KLRG1, and increased BCL2; 
     and wherein any of the foregoing, e.g., i), ii), iii), iv), v), vi), or vii), occurs e.g., at least transiently, e.g., as compared to a non-treated subject. 
     In another embodiment, administration of a low, immune enhancing, dose of an mTOR inhibitor results in increased or prolonged proliferation or persistence of CAR-expressing cells, e.g., in culture or in a subject, e.g., as compared to non-treated CAR-expressing cells or a non-treated subject. In embodiments, increased proliferation or persistence is associated with in an increase in the number of CAR-expressing cells. Methods for measuring increased or prolonged proliferation are described in Examples 15 and 16. In another embodiment, administration of a low, immune enhancing, dose of an mTOR inhibitor results in increased killing of cancer cells by CAR-expressing cells, e.g., in culture or in a subject, e.g., as compared to non-treated CAR-expressing cells or a non-treated subject. In embodiments, increased killing of cancer cells is associated with in a decrease in tumor volume. Methods for measuring increased killing of cancer cells are described herein, e.g., in Examples 2, 5-6, 8, and 13. In one embodiment, the cells expressing a CAR molecule, e.g., a CAR molecule described herein, are administered in combination with a low, immune enhancing dose of an mTOR inhibitor, e.g., an allosteric mTOR inhibitor, e.g., RAD001, or a catalytic mTOR inhibitor. For example, administration of the low, immune enhancing, dose of the mTOR inhibitor can be initiated prior to administration of a CAR-expressing cell described herein; completed prior to administration of a CAR-expressing cell described herein; initiated at the same time as administration of a CAR-expressing cell described herein; overlapping with administration of a CAR-expressing cell described herein; or continuing after administration of a CAR-expressing cell described herein. 
     Alternatively or in addition, administration of a low, immune enhancing, dose of an mTOR inhibitor can optimize immune effector cells to be engineered to express a CAR molecule described herein. In such embodiments, administration of a low, immune enhancing, dose of an mTOR inhibitor, e.g., an allosteric inhibitor, e.g., RAD001, or a catalytic inhibitor, is initiated or completed prior to harvest of immune effector cells, e.g., T cells or NK cells, to be engineered to express a CAR molecule described herein, from a subject. 
     In another embodiment, immune effector cells, e.g., T cells or NK cells, to be engineered to express a CAR molecule described herein, e.g., after harvest from a subject, or CAR-expressing immune effector cells, e.g., T cells or NK cells, e.g., prior to administration to a subject, can be cultured in the presence of a low, immune enhancing, dose of an mTOR inhibitor. 
     In an embodiment, administering to the subject a low, immune enhancing, dose of an mTOR inhibitor comprises administering, e.g., once per week, e.g., in an immediate release dosage form, 0.1 to 20, 0.5 to 10, 2.5 to 7.5, 3 to 6, or about 5, mgs of RAD001, or a bioequivalent dose thereof. In an embodiment, administering to the subject a low, immune enhancing, dose of an mTOR inhibitor comprises administering, e.g., once per week, e.g., in a sustained release dosage form, 0.3 to 60, 1.5 to 30, 7.5 to 22.5, 9 to 18, or about 15 mgs of RAD001, or a bioequivalent dose thereof. 
     In an embodiment, a dose of an mTOR inhibitor is associated with, or provides, mTOR inhibition of at least 5 but no more than 90%, at least 10 but no more than 90%, at least 15, but no more than 90%, at least 20 but no more than 90%, at least 30 but no more than 90%, at least 40 but no more than 90%, at least 50 but no more than 90%, at least 60 but no more than 90%, at least 70 but no more than 90%, at least 5 but no more than 80%, at least 10 but no more than 80%, at least 15, but no more than 80%, at least 20 but no more than 80%, at least 30 but no more than 80%, at least 40 but no more than 80%, at least 50 but no more than 80%, at least 60 but no more than 80%, at least 5 but no more than 70%, at least 10 but no more than 70%, at least 15, but no more than 70%, at least 20 but no more than 70%, at least 30 but no more than 70%, at least 40 but no more than 70%, at least 50 but no more than 70%, at least 5 but no more than 60%, at least 10 but no more than 60%, at least 15, but no more than 60%, at least 20 but no more than 60%, at least 30 but no more than 60%, at least 40 but no more than 60%, at least 5 but no more than 50%, at least 10 but no more than 50%, at least 15, but no more than 50%, at least 20 but no more than 50%, at least 30 but no more than 50%, at least 40 but no more than 50%, at least 5 but no more than 40%, at least 10 but no more than 40%, at least 15, but no more than 40%, at least 20 but no more than 40%, at least 30 but no more than 40%, at least 35 but no more than 40%, at least 5 but no more than 30%, at least 10 but no more than 30%, at least 15, but no more than 30%, at least 20 but no more than 30%, or at least 25 but no more than 30%. 
     In an embodiment, administering to the subject a low, immune enhancing, dose of an mTOR inhibitor comprises administering, e.g., once per week, e.g., in an immediate release dosage form, 0.1 to 20, 0.5 to 10, 2.5 to 7.5, 3 to 6, or about 5, mgs of RAD001, or a bioequivalent dose thereof. In an embodiment, administering to the subject a low, immune enhancing, dose of an mTOR inhibitor comprises administering, e.g., once per week, e.g., in a sustained release dosage form, 0.3 to 60, 1.5 to 30, 7.5 to 22.5, 9 to 18, or about 15 mgs of RAD001, or a bioequivalent dose thereof. 
     The extent of mTOR inhibition can be conveyed as, or corresponds to, the extent of P70 S6 kinase inhibition, e.g., the extent of mTOR inhibition can be determined by the level of decrease in P70 S6 kinase activity, e.g., by the decrease in phosphorylation of a P70 S6 kinase substrate. The level of mTOR inhibition can be evaluated by various methods, such as measuring P70 S6 kinase activity by the Boulay assay, as described in U.S. Patent Application No. 2015/01240036, hereby incorporated by reference, or as described in U.S. Pat. No. 7,727,950, hereby incorporated by reference; measuring the level of phosphorylated S6 by western blot; or evaluating a change in the ratio of PD1 negative immune effector cells to PD1 positive immune effector cells. 
     As used herein, the term “mTOR inhibitor” refers to a compound or ligand, or a pharmaceutically acceptable salt thereof, which inhibits the mTOR kinase in a cell. In an embodiment, an mTOR inhibitor is an allosteric inhibitor. Allosteric mTOR inhibitors include the neutral tricyclic compound rapamycin (sirolimus), rapamycin-related compounds, that is compounds having structural and functional similarity to rapamycin including, e.g., rapamycin derivatives, rapamycin analogs (also referred to as rapalogs) and other macrolide compounds that inhibit mTOR activity. In an embodiment, an mTOR inhibitor is a catalytic inhibitor. 
     Rapamycin is a known macrolide antibiotic produced by  Streptomyces hygroscopicus  having the structure shown in Formula A.

     EXAMPLES 
     A. Example 1 
     Multiple myeloma (MM) is the second most common hematologic malignancy causing approximately 12,500 deaths this year in the U.S. alone. While there have been considerable therapeutic advances in the past decade, this cancer is still considered incurable and despite initial responses, practically all patients will eventually experience a fatal relapse. Relapses are thought to be due to chemotherapy-resistant NM propagating cells that persist even after the destruction of the bulk of tumor cells by chemotherapy. This population needs to be targeted effectively in addition to the tumor bulk to achieve lasting remissions and cures in MM. 
     Chimeric antigen receptors (CARs) are engineered proteins containing domains for antigen binding, structure/scaffolding and effector cell signaling. In its most common form a single chain variable fragment (scFv) is used for antigen binding, parts of CD8 or the immunoglobulin hinge/transmembrane domains to provide essential structural elements, and signaling domains derived from CD3ζ and CD28 or 4-1BB for T cell activation. It has been shown that autologous T cells expressing CARs directed against CD19 have strong clinical activity against CD19+ lymphoid malignancies, particularly B-ALL and a number of trials have been initiated to treat various hematological and some solid cancers using CAR T cells. The advantage of using CAR T cells versus a monoclonal antibody with the same specificity is that such an approach combines the specificity of an antibody with the durability and efficacy of a memory T cell response targeting MM. 
     Antigens currently investigated as targets for CAR T cells in MM include CD138, immunoglobulin kappa light chain, CD19, and BCMA. For CD138 and kappa light chain-specific CAR T cells no results have been reported yet. For CD19 a single case has been reported, indicating clinical activity of CART cells despite the absence of CD19 expression from the bulk of MM cells. Encouraging results from an early-phase clinical trial have been reported for BCMA-specific CAR T cells, with a complete response and a very good partial response in the two patients treated at the highest dose level. Whether these responses will be durable remains to be seen, as BCMA is absent from naïve and memory B cells, which represent a reservoir for MM-precursor cells that are considered responsible for the frequent relapses in MM. CS-1 is a member of the SLAM family of lymphocyte receptors and the target of elotuzumab, a monoclonal antibody with some clinical activity in MM. A study of CAR T cells targeting CS-1 in MM is underway, but no clinical results have been reported yet. 
     1. Tissue Distribution and Antibody Targeting of CD229. 
     CD229, a SLAM family member, is strongly expressed on the surface of MM cell lines and primary MM cells ( FIG.  1 A ). Importantly knockdown of CD229 significantly reduces the clonogenicity of MM cell lines, indicating a significant barrier toward immune escape through downregulation of CD229 ( FIG.  1 B ). Studies also show that CD229 plays an anti-apoptotic role in MM, indicating another barrier toward immune escape. Using a murine monoclonal antibody against human CD229 it was also found that this antigen can be targeted efficiently via complement-derived cytotoxicity (CDC) and antibody dependent cellular cytotoxicity (ADCC,  FIG.  1 C ). CD229 is absent from the vast majority of tissues ( FIG.  1 D ) including CD34+ hematopoietic stem/progenitor cells, with expression limited to lymphatic tissues ( FIG.  1 E ). As interconversion of myeloma plasma cell populations with different antigen expression patterns and resistance to current treatment regimens has been reported ( FIG.  1 F ), CD229 expression on MM cellular subsets was analyzed. CD229 is homogeneously and strongly expressed not only on the bulk of MM cells but also myeloma precursors ( FIG.  1 G ). These data strongly indicate that CD229 represents a promising target for CAR T cell therapy in MM due to its expression on all relevant malignant cell populations, which should result in deeper remissions or even cures. 
     2. Identification of Anti-CD229 scFv Domains. 
     As no monoclonal anti-CD229 antibodies were available for conversion to CAR format, novel high-affinity scFv domains were generated for use in anti-CD229 CAR constructs and mined a human antibody phage display library with a diversity of &gt;1010 clones ( FIG.  2 A ). As this library is derived from human immunoglobulin genes, the immunogenicity of the resulting CAR constructs in humans is expected to be low compared to CARs using murine or partially humanized antibody domains. Antibodies in the library are displayed as scFv domains and contain both heavy and light chain variable regions connected by a linker, enabling rapid conversion from phage to CARs once binders are identified. After two rounds of specific enrichment of phage binders by panning, 1,323 clones specific for the extracellular domain (ECD) of human CD229 were obtained. After further selection and bacterial expression of 168 clones, 32 CD229 binders were chosen for additional studies based on time-resolved fluorescence (TRF) signal intensity ≥5-fold over background ( FIG.  2 B ); 23 of these clones were identified to have unique heavy and light chain combinations by Sanger sequencing. 
     3. Generation of Anti-CD229 CAR T Cells. 
     In the final CAR construct, the scFv can be be joined directly to a 45 amino acid hinge domain, which can alter binding properties of the antibodies. In order to identify clones likely to be amenable to CAR conversion, the scFv was fused to an immunoglobulin Fc domain (scFv-Fc fusion,  FIG.  2 C ) and the constructs were expressed in human 293T cells. 20 of the 23 unique scFv binders still recognized CD229 with the new C-terminal fusion partner. All 23 unique binders were then cloned into the CAR vector ( FIG.  2 D ). The second-generation CAR construct uses a CD8α hinge and transmembrane domain with a CD3ζ signaling and a 4-1BB co-stimulatory domain. In addition a hemagglutinin (HA) tag was added between the scFv and hinge domains to allow the simultaneous assessment of antigen binding and surface expression ( FIG.  2 D ). Individual CAR constructs were expressed in 293T cells, and analyzed by flow cytometry after staining with allophycocyanin (APC)-labeled recombinant CD229 and a phycoerythrin (PE)-labeled anti-HA antibody. 15 of the 23 constructs showed high surface expression and CD229 binding ( FIG.  2 E ). Interestingly, results from the two soluble antibody-screening assays did not correlate with the cell-based screening assay indicating unique binding behavior of CARs ( FIG.  2 F ). 
     CD3/CD28 bead-activated primary human T cells were transduced with lentiviral particles generated from these 15 CAR constructs and GFP control plasmids. The ability of immobilized recombinant CD229 to activate the CAR T cells was compared. Twelve of the 15 constructs showed T cell activation as determined by increased IFNγ production measured by intracellular cytokine staining and flow cytometry analysis ( FIG.  3 A ). 
     The 15 constructs comprise sequences shown in Table 11.

     4. Initial Analyses Regarding SLAM Cross-Reactivity. 
     Using scFv-Fc variants of the CAR binders, which were expressed in mammalian 293F cells, an initial analysis of cross-reactivity of four randomly chosen constructs was performed against a smaller panel of SLAM family receptors. None of these clones were cross-reactive to SLAM/CD150, SLAMF2/CD48, SLAMF8/BLAME, or murine CD229 ( FIG.  3 B ). 
     5. Autotargeting of T Cells by Anti-CD229 CAR T Cells. 
     The fact that CD229 is expressed on normal T and NK cells indicates a potential for autotargeting. Growth kinetics of primary human T cells transduced with anti-CD229 CAR constructs and enriched &gt;90% by FACS for CAR expression were analyzed, but no significant differences compared to T cells transduced with GFP as a control were observed ( FIG.  3 C ). In addition, a cytotoxicity assay was performed using two of the activating CAR constructs and no significant cytotoxicity towards healthy autologous T cells was observed ( FIG.  4 B ). These results indicate that CD229 targeting CARs have no significant killing activity against themselves or autologous T cells. This is consistent with recent studies demonstrating that normal T and NK cells are resistant to CAR effector cells despite potent tumor cell lysis. It is thought that this reflects the ability of healthy T cells, but not tumor cells, to rapidly downregulate target antigens and upregulate protective pathways that prevent their lysis. 
     6. Cytotoxic Activity Against K562 Cells Expressing CD229 and Autologous T Cells. 
     A truncated variant of CD229 lacking its intracellular signalling domains was expressed in human K562 cells (K562-CD229), which do not express HLA class I molecules and are therefore not subject to killing by potentially alloreactive T cells. In addition, autologous untransduced T cells were cultured in parallel to transduced T cell populations and also used as target cells. K562-CD229 cells and autologous untransduced T cells were labelled with calcein AM and incubated for 4h with effector T cell populations. Purified anti-CD229 CAR T cells expressing clone 2D3 or clone 2A2, which had shown substantial surface expression, antigen binding, and increased IFNγ expression after CD229-crosslinking, or T cells transduced with GFP only were used as effector populations and co-cultures were analyzed by flow cytometry ( FIG.  4 A ). T cells expressing anti-CD229 CARs showed significant dose-dependent lysis of CD229 expressing K562-CD229 cells but no or limited cytotoxicity towards healthy T cells ( FIG.  4 B ) These results provide proof of principle that specifically targeting cancer cells expressing CD229 using the CAR T cells is feasible. 
     B. Example 2 
     T cells engineered to express CARs (CAR T cells) targeting CD19 are highly effective in refractory B-cell acute lymphoblastic leukemia (B-ALL). For instance, a pediatric B-ALL study reported a complete remission (CR) rate of 92%, with 76% of responses sustained at 6 months. In MM, however, the efficacy of CD19-specific CAR T cell therapy remains uncertain. While one successful case was reported last year, the vast majority of MM cells do not express CD19. CAR T cells targeting B-cell maturation antigen (BCMA), the immunoglobulin kappa light chain, CD138, and CS1 have specifically been developed for MM therapy. No responses were observed for CAR T cells targeting immunoglobulin kappa or CD138, and there are no clinical trials investigating CS-1 CAR T cells, presumably due to its wide off-tissue expression on many normal immune cells. CAR T cells targeting B-cell maturation antigen (BCMA), an antigen expressed with exquisite specificity on terminally differentiated plasma and MM cells, have resulted in promising overall response rates in multiple clinical trials. While these findings are very encouraging and demonstrate the potential utility of CAR T cells as a treatment for MM, these are early results. Long-term outcomes remain uncertain, as the only published report on the clinical efficacy of BCMA CAR T cells described elapses in all treated patients. This observation would be in line with the absence of BCMA from MM precursor cells, which are considered responsible for the frequent relapses in this disease. In addition, to the best of our knowledge, eligibility criteria for all ongoing clinical trials using BCMA CAR T cells include confirmation of substantial surface expression of BCMA. While there is a surprising lack of information regarding BCMA expression in larger cohorts of patients with MM and no such information is yet available from the ongoing clinical trials, data indicates that only a minority of patients would be eligible due to high heterogeneity of BCMA expression in patients with MM. Hence, there is a need for novel CAR T cell approaches targeting antigens that are frequently expressed at high levels on MM cells and that are present not only on terminally differentiated MM plasma cells but also on their more therapy-resistant precursors. 
     CD229, a member of the SLAM (signaling lymphocyte activation molecule) family of proteins, is strongly expressed on terminally differentiated MM plasma cells, but absent from any non-lymphoid tissues and CD34+ hematopoietic stem cells. Importantly, CD229 is also expressed on CD19-138-MM pre-plasma cells, and memory B cells, another potential reservoir of MM precursor cells. In MM cells, CD229 confers resistance to spontaneous apoptosis and it can be targeted efficiently using a murine monoclonal antibody. However, a potential issue with CD229 as a therapeutic target is its relatively strong expression on healthy T and NK cells. CAR T cells targeting a variant of CD229 have been developed, termed CD229 CT2 , wherein the variant of CD229 is specifically expressed on all populations harboring MM cells. Importantly, on healthy cells CD229 CT2  is not expressed on activated T cells and NK cells and is only found at low levels on a subpopulation of resting T cells and B cells, potentially allowing the exclusive targeting of MM cells by modulating CAR T cell avidity. A CAR T cell approach targeting this antigen in MM can result in sustained remissions or even cures. 
     1. Validation of CD229 CT2  as a Target for CAR T Cell Therapy for Human MM. 
     CD229 located on chromosome arm 1q, which is frequently amplified in MM, is expressed on MM precursor cells and terminally differentiated MM plasma cells. Eradicating both populations simultaneously using CD229 CT2  CAR T cells may lead to more durable responses or even cures. 
     i. Tissue Distribution and Antibody Targeting of CD229. 
     It was previously reported that CD229 is strongly expressed on the surface of MM cell lines and primary MM cells. As interconversion of myeloma plasma cell populations with different antigen expression patterns and resistance to current treatment regimens has been reported ( FIG.  6 A ), CD229 expression was analyzed on various cellular subsets of MM. It was demonstrated that CD229 is homogeneously and strongly expressed not only on the bulk of MM cells but also on myeloma precursors ( FIG.  6 B ). Knockdown of CD229 significantly reduces the clonogenicity of MM cell lines, indicating a significant barrier toward immune escape through downregulation of CD229 ( FIG.  6 C ). Using a murine monoclonal antibody against human CD229 it was also found that this antigen can be targeted efficiently via complement derived cytotoxicity (CDC) and antibody dependent cellular cytotoxicity. CD229 is absent from tissues other than lymphatic tissues ( FIG.  6 D ). 
     ii. Expression of Common CAR Targets on Healthy Blood Cell Subsets and Bone Marrow B Cell Precursors. 
     BCMA is currently being evaluated as a target of CAR T cell therapies for the treatment of MM. BCMA is a receptor for the TNF superfamily ligand APRIL. Another receptor for APRIL is transmembrane activator and CAML interactor (TACI). A CAR using APRIL as its binding domain targeting cells expressing either BCMA or TACI has been developed and can counteract selection of variants that are single-negative for either BCMA or TACI. Another antigen against which CART cells have been developed for the treatment of MM is CS-1. Like CD229, CS-1 belongs to the SLAM family of receptors. The monoclonal antibody elotuzumab, which targets CS-1, has been approved for the treatment of MM. The expression of CD229 was compared to these three targets on healthy peripheral blood cell subsets, CD34+ hematopoietic stem cells, bone-marrow B lineage cells, as well as MM cell lines, and primary human MM cells. Using flow cytometry, it was found that all four targets are absent from CD34+ hematopoietic stem cells ( FIG.  6 E ). It was further confirmed that CD229 is expressed on T, B, and NK cells, while BCMA and TACI appeared to be absent from all analyzed peripheral blood cell subsets, with the possible exception of low-level BCMA expression on neutrophils and monocytes ( FIG.  6 F ). Importantly, it was found that CS-1 was broadly expressed on almost all healthy cell subsets, though only showing low expression on B cells ( FIG.  6 F ). Analyzing B lineage cells in bone-marrow samples from patients with MM, all targets were absent from the earliest stages of B cell development and, in the case of CS-1 and BCMA, any B lineage cells except for plasma cells ( FIG.  6 G ). In contrast, CD229 expression is apparent at the transitional B cell stage and continues through the plasma cell stage. This finding is important, since malignant transformation of MM cells is known to occur at the memory B cell stage. In contrast, targeting BCMA and CS-1 would only eradicate terminally differentiated MM plasma cells. Finally, analyzing MM cells, strong expression of both CD229 and CS-1 were observed, and comparably low levels of BCMA expression ( FIG.  6 G ). Previous reports have shown more variable BCMA expression including relatively high expression but also the absence of detectable BCMA expression in some cases. Surprisingly, TACT expression was only observed on MM cell line RPMI-8226 but not on any primary MM cells. From these preliminary analyses it was concluded that CD229 can be superior to others targets, capturing MM cells at all stages of the disease and showing homogeneous and high expression on the malignant cells of all analyzed patients. 
     iii. Identification of Anti-CD229 scFv Domains. 
     As no human monoclonal anti-CD229 antibodies were available for conversion to CAR format, novel high-affinity scFv domains were generated for use in the anti-CD229 CAR constructs. A human antibody phage display library with a diversity of &gt;10 10  clones was mined ( FIG.  7 A ). As the library is derived from human immunoglobulin genes, the immunogenicity of the resulting CAR constructs in humans is expected to be low compared to CARs using murine or partially humanized antibody domains. Antibodies in the library are displayed as scFv domains and contain both heavy and light chain variable regions connected by a linker, enabling rapid conversion from phage to CARs once binders are identified. After two rounds of specific enrichment of phage binders by panning, 1,323 clones specific for the extracellular domain (ECD) of human CD229 were obtained. After further selection and bacterial expression of 168 clones, 32 CD229 binders were chosen for additional studies based on time-resolved florescence (TRF) signal intensity ≥5-fold over background ( FIG.  7 B ); 23 of these clones were identified to have unique heavy and light chain combinations by Sanger sequencing. 
     iv. Generation of CD229-Specific Antibodies and CAR Constructs. 
     In the final CAR construct, the scFv can be joined directly to a 45 amino acid hinge domain, which can alter binding properties of the antibodies. In order to identify clones likely to be amenable to CAR conversion, the scFv was fused to an immunoglobulin Fc domain (scFv-Fc fusion,  FIG.  7 C ) and the constructs were expressed in human 293T cells. 20 of the 23 unique scFv binders still recognized CD229 with the new C-terminal fusion partner. All 23 unique binders were cloned into the CAR vector ( FIG.  7 D ). The second-generation CAR construct uses a CD8α hinge and transmembrane domain with a CD3ζ signaling and a 4-1BB costimulatory domain. In addition, a hemagglutinin (HA) tag was added between the scFv and hinge domains to allow the simultaneous assessment of antigen binding and surface expression ( FIG.  7 D ). Individual CAR constructs were expressed in 293T cells, and analyzed by flow cytometry after staining with allophycocyanin (APC)-labeled recombinant CD229 and a phycoerythrin (PE)-labeled anti-HA antibody. The majority, 15 of the 23 constructs, showed high surface expression and CD229 binding ( FIG.  7 E ). In line with the previously described importance of the 45 amino acid hinge domain for CAR activity, results from the two soluble antibody-screening assays showed limited correlation with the cell-based screening assay confirming the unique binding behavior of CARs ( FIG.  7 F ). 
     Using a high-throughput surface plasmon resonance (SPR) assay, the crossreactivity and binding kinetics of the antibodies to all SLAM family members were determined. It was found that our antibodies had low nanomolar affinities to CD229 ( FIG.  7 G ) and that the antibodies did not bind to any other SLAM receptors with any measurable affinity ( FIG.  7 H ). For all downstream analyses clone 2D3 was selected, which was found to perform well in all assays. The specificity of 2D3 was confirmed. CD229 was overexpressed in 293T cells and these cells were stained with 2D3. It was found that the antibody did not stain parental 293T cells but that it bound strongly to transfected 293T cells ( FIG.  7 I ) further confirming its specificity for CD229. Healthy lymphocyte subsets as well as primary MM cells and MM cell lines were stained, and binding was analyzed by flow cytometry. In contrast to previous findings using the commercially available CD229 antibody HLy9.1.25 ( FIG.  7 F ) only minor staining by 2D3 was observed on resting T cells and B cells, and no staining of NK cells or activated T cells ( FIG.  7 J ). Importantly, strong staining of MM cell line U266 and even stronger staining of primary CD19-CD38+CD138+MM plasma cells was still observed ( FIG.  7 J ). In order to investigate the differential binding of 2D3 to healthy lymphocytes, expression of CD229 isoforms was determined by qualitative RT-PCR. CD229 isoform 3 lacks a large extracellular domain proximal to the transmembrane domain corresponding to the C2-type 2 domain of CD229, while isoforms 1, 2, and 4 contain this region ( FIG.  7 K ). Lower expression of isoforms 1, 2, and 4 were observed in activated T cells ( FIG.  7 L ). 2D3 recognizes a variant of CD229 by binding to an epitope within the extracellular C2-type 2 domain of CD229, which is absent or inaccessible in the majority of healthy lymphocyte subsets. This variant, or group of variants, was termed CD229 CT2 . 
     v. CD229 CT2  CAR Manufacturing and Anti-MM Efficacy. 
     A second generation CD229 CT2 —and, for comparative purposes, CD19-specific CAR T cells using the 4-1BB costimulatory and CD8a hinge and transmembrane domains was generated. In order to generate the CD19-specific CAR the CD229 CT2 -specific scFv domain was replaced with the previously described CD19-specific scFv clone FMC63. Using lentiviral gene transfer primary human T cells expressing each CAR was engineered. In order to address the possibility of undesired spontaneous T cell activation in the absence of antigen, called tonic signaling, by the construct PD-1 expression ( FIG.  8 A ) and expansion ( FIG.  8 B ) of the CD229 CT2  CAR T cells was determined. Importantly, the CAR T cells did not show any signs of early exhaustion, a hallmark of tonic signaling. Analyzing the T cell phenotype during CAR T cell production, CD229 CT2  CAR T cell phenotypes mirrored those of CD19 CART cells ( FIG.  8 C ). The cytotoxic activity of the CAR T cells was determined using various target cells. CD229 CAR T cells showed strong cytotoxic activity against K562 cells transduced with a CD229 expression construct, but only limited cytotoxicity against parental K562 cells ( FIG.  8 D ). 
     Strong cytotoxic activity against the CD229-positive MM cell lines U266 and RPMI-8226 at low effector-target ratios was observed, in contrast to minimal killing by T cells transduced with a GFP control construct ( FIG.  8 E ). Using cells manufactured according to the most recent protocol even at effector-target ratios of 1:10 and 1:5 strong killing of the MM cell line U266 was observed ( FIG.  8 F ). The cytotoxic activity against healthy lymphocyte subsets, which we had previously found to express CD229 using HLy9.1.25 but which showed little or no binding by 2D3 was determined. Importantly, only killing of B cells and resting T cells was observed, while no cytotoxic activity was observed against T cells activated with CD3/CD28 beads or NK cells ( FIG.  8 G ). Lack of killing of activated T cells also explains the undisturbed expansion of the CD229 CAR T cells during manufacturing ( FIG.  8 A ) and correlates with the binding data ( FIG.  7 I ). Cytotoxicity against purified CD34+ hematopoietic stem cells was also not observed (data not shown). Finally, the in vivo efficacy of CD229 and CD19 CAR T cells was determined using immunocompromised NOD.Cg-Prkdc scid Il2rg tm1Wj1 /SzJ (NSG) mice after engraftment with U266 cells. We found that CD229 CT2  CAR T cells had completely eradicated MM cells expressing luciferase after only 18 days, while mice treated with CD19 CART cells or PBS still showed strong bioluminescence signal ( FIG.  8 H ). In addition to demonstrating strong anti-MM efficacy, this result further confirms the absence of tonic signaling, as this phenomenon is accompanied by poor in vivo activity. 
     The binding of clone 2D3 to Burkitt&#39;s lymphoma cell lines Daudi and Raji was demonstrated ( FIG.  9   ). This result is in line with the finding that CD229 is widely expressed on B lineage cells and demonstrates that the CD229 CAR T cells are able to target not only multiple myeloma but also other malignancies, such as lymphoma.
