BACKGROUND OF THE INVENTION

[0003] Cancer is the second leading cause of human death next to coronary disease. Worldwide, millions of people die from cancer every year. In the United States alone, cancer causes the death of well over a half-million people each year, with some 1.4 million new cases diagnosed per year. While deaths from heart disease have been declining significantly, those resulting from cancer generally are on the rise. In the early part of the next century, cancer is predicted to become the leading cause of death.

[0004] Moreover, even for those cancer patients that initially survive their primary cancers, common experience has shown that their lives are dramatically altered. Many cancer patients experience strong anxieties driven by the awareness of the potential for recurrence or treatment failure. Many cancer patients experience significant physical debilitations following treatment. [0005] Generally speaking, the fundamental problem in the management of the deadliest cancers is the lack of effective and non-toxic systemic therapies. Cancer is a complex disease characterized by genetic mutations that lead to uncontrolled cell growth. Cancerous cells are present in all organisms and, under normal circumstances, their excessive growth is tightly regulated by various physiological factors.

SUMMARY OF THE INVENTION

[0006] The selective destruction of an individual cell or a specific cell type is often desirable in a variety of clinical settings. For example, it is a primary goal of cancer therapy to specifically destroy tumor cells, while leaving healthy cells and tissues intact and undamaged. One such method is by inducing an immune response against the tumor, to make immune effector cells such as natural killer (NK) cells or cytotoxic T lymphocytes (CTLs) attack and destroy tumor cells.

[0007] Provided herein is a B cell maturation agent (BCMA) binding trispecific protein that comprises: (a) a first domain (A) which specifically binds to human CD3; (b) a second domain -1WO 2019/075359 (B) which is a half-life extension domain; and (c) a third domain (C) which specifically binds to BCMA, wherein the domains are linked in the order H2N-(A)-(C)-(B)-COOH, H2N-(B)-(A)-(C)COOH, H2N-(C)-(B)-(A)-COOH, H2N-(C)-(A)-(B)-COOH, H2N-(A)-(B)-(C)-COOH, 0rH2N(B)-(C)-(A)-COOH, wherein the domains are linked by linkers LI and L2.

DETAILED DESCRIPTION OF THE INVENTION

[0085] While preferred embodiments of the present invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed in practicing the invention. It is intended that the following claims define the scope of the invention and that methods and structures within the scope of these claims and their equivalents be covered thereby.

[0086] Described herein are trispecific proteins that target B cell maturation antigen (BCMA), pharmaceutical compositions thereof (referred to herein as BCMA binding trispecific protein, BCMA targeting trispecific protein, or BCMA trispecific antigen-binding protein) as well as nucleic acids, recombinant expression vectors and host cells for making such proteins thereof. Also provided are methods of using the disclosed BCMA targeting trispecific proteins in the prevention, and/or treatment of diseases, conditions and disorders. The BCMA targeting trispecific proteins are capable of specifically binding to BCMA as well as CD3 and have a halflife extension domain, such as a domain binding to human albumin (ALB). Fig. 1 depicts a nonlimiting example of a trispecific BCMA-binding protein.

[0087] An “antibody” typically refers to a Y-shaped tetrameric protein comprising two heavy (H) and two light (L) polypeptide chains held together by covalent disulfide bonds and non-covalent interactions. Human light chains comprise a variable domain (VL) and a constant domain (CL)

wherein the constant domain may be readily classified as kappa or lambda based on amino acid sequence and gene loci. Each heavy chain comprises one variable domain (VH) and a constant region, which in the case of IgG, IgA, and IgD, comprises three domains termed CHI, CH2, and CH3 (IgM and IgE have a fourth domain, CH4). In IgG, IgA, and IgD classes the CHI and CH2 domains are separated by a flexible hinge region, which is a proline and cysteine rich segment of variable length (generally from about 10 to about 60 amino acids in IgG). The variable domains in both the light and heavy chains are joined to the constant domains by a “J” region of about 12 or more amino acids and the heavy chain also has a “D” region of about 10 additional amino acids. Each class of antibody further comprises inter-chain and intra-chain disulfide bonds formed by paired cysteine residues. There are two types of native disulfide bridges or bonds in immunoglobulin molecules: inter-chain and intra-chain disulfide bonds. The location and number of inter-chain disulfide bonds vary according to the immunoglobulin class and species. Interchain disulfide bonds are located on the surface of the immunoglobulin, are accessible to solvent and are usually relatively easily reduced. In the human IgGl isotype there are four inter-chain disulfide bonds, one from each heavy chain to the light chain and two between the heavy chains. The inter-chain disulfide bonds are not required for chain association. As is well known the cysteine rich IgGl hinge region of the heavy chain has generally been held to consist of three parts: an upper hinge, a core hinge, and a lower hinge. Those skilled in the art will appreciate that the IgGl hinge region contains the cysteines in the heavy chain that comprise the inter-chain disulfide bonds (two heavy/heavy, two heavy/light), which provide structural flexibility that facilitates Fab movements. The inter-chain disulfide bond between the light and heavy chain of IgGl are formed between C214 of the kappa or lambda light chain and C220 in the upper hinge region of the heavy chain. The inter-chain disulfide bonds between the heavy chains are at positions C226 and C229 (all numbered per the EU index according to Kabat, et al., infra.).

[0088] As used herein the term “antibody” includes polyclonal antibodies, multiclonal antibodies, monoclonal antibodies, chimeric antibodies, humanized and primatized antibodies, CDR grafted antibodies, human antibodies, recombinantly produced antibodies, intrabodies, multispecific antibodies, bispecific antibodies, monovalent antibodies, multivalent antibodies, anti-idiotypic antibodies, synthetic antibodies, including muteins and variants thereof, immunospecific antibody fragments such as Fd, Fab, F(ab')2, F(ab') fragments, single-chain fragments (e.g., ScFv and ScFvFc), disulfide-linked Fvs (sdFv), a Fd fragment consisting of the VH and CHI domains, linear antibodies, single domain antibodies such as sdAb (VH, VL, or VHH domains); and derivatives thereof including Fc fusions and other modifications, and any other immunoreactive molecule so long as it comprises a domain having a binding site for preferential association or binding with a BCMA protein. Moreover, unless dictated otherwise by

contextual constraints the term further comprises all classes of antibodies (i.e. IgA, IgD, IgE, IgG, and IgM) and all subclasses (i.e., IgGl, IgG2, IgG3, IgG4, IgAl, and IgA2). Heavy-chain constant domains that correspond to the different classes of antibodies are typically denoted by the corresponding lower case Greek letter alpha , delta , epsilon , gamma, and mu , respectively. Light chains of the antibodies from any vertebrate species can be assigned to one of two clearly distinct types, called kappa (kappa) and lambda (lambda), based on the amino acid sequences of their constant domains.

[0089] In some embodiments, the BCMA binding domain of the BCMA targeting trispecific proteins of this disclosure comprise a heavy chain only antibody, such as a VH or a VHH domain. In some cases, the BCMA binding proteins comprise a heavy chain only antibody that is an engineered human VH domain. In some examples, the engineered human VH domain is produced by panning of phage display libraries. In some embodiments, the BCMA binding domain of the BCMA targeting trispecific proteins of this disclosure comprise a VHH. The term “VHH,” as used herein, refers to single chain antibody binding domain devoid of light chain. In some cases, a VHH is derived from an antibody of the type that can be found in Camelidae or cartilaginous fish which are naturally devoid of light chains or to a synthetic and non-immunized VHH which can be constructed accordingly. Each heavy chain comprises a variable region encoded by V-, D- and J exons. A VHH, in some cases, is a natural VHH, such as a Camelidderived VHH, or a recombinant protein comprising a heavy chain variable domain. In some embodiments, the VHH is derived from a species selected from the group consisting of camels, llamas, vicugnas, guanacos, and cartilaginous fish (such as, but not limited to, sharks). In another embodiment, the VHH is derived from an alpaca (such as, but not limited to, a Huacaya Alpaca or a Suri alpaca).

[0090] As used herein, “Variable region” or “variable domain” refers to the fact that certain portions of the variable domains differ extensively in sequence among antibodies and are used in the binding and specificity of each particular antibody for its particular antigen. However, the variability is not evenly distributed throughout the variable domains of antibodies. It is concentrated in three segments called complementarity-determining regions (CDRs) or hypervariable regions both in the light-chain (VL) and the heavy-chain (VH) variable domains. The more highly conserved portions of variable domains are called the framework (FR). The variable domains of native heavy and light chains each comprise four FR regions, largely adopting a β-sheet configuration, connected by three CDRs, which form loops connecting, and in some cases forming part of, the β sheet structure. The CDRs in each chain are held together in close proximity by the FR regions and, with the CDRs from the other chain, contribute to the formation of the anti gen-binding site of antibodies (see Kabat et al., Sequences of Proteins of

Immunological Interest, Fifth Edition, National Institute of Health, Bethesda, Md. (1991)). The constant domains are not involved directly in binding an antibody to an antigen, but exhibit various effector functions, such as participation of the antibody in antibody-dependent cellular toxicity. ScFv fragments (or single chain fragment variable), which in some cases are obtained by genetic engineering, associate in a single polypeptide chain, the VH and the VL region of an antibody, separated by a peptide linker.

[0091] In some embodiments of this disclosure, the BCMA binding domain of the BCMA targeting trispecific proteins comprise heavy chain only antibodies, such as VH or VHH domains, and comprise three CDRs. Such heavy chain only antibodies, in some embodiments, bind BCMA as a monomer with no dependency on dimerization with a VL (light chain variable) region for optimal binding affinity. In some embodiments of this disclosure, the CD3 binding domain of the BCMA targeting trispecific proteins comprises a scFv. In some embodiments of this disclosure, the albumin binding domain of the BCMA targeting trispecific proteins comprise a heavy chain only antibody, such as a single domain antibody comprising a VH domain or a VHH domain.

[0092] The assignment of amino acids to each domain, framework region and CDR is, in some embodiments, in accordance with one of the numbering schemes provided by Kabat et al. (1991) Sequences of Proteins of Immunological Interest (5th Ed.), US Dept, of Health and Human Services, PHS, NIH, NIH Publication no. 91-3242; Chothia et al., 1987, PMID: 3681981;

Chothia etal., 1989, PMID: 2687698; MacCallum etal., 1996, PMID: 8876650; or Dubel, Ed. (2007) Handbook of Therapeutic Antibodies, 3rd Ed., Wily-VCH Verlag GmbH and Co or AbM (Oxford Molecular/MSI Pharmacopia) unless otherwise noted. It is not intended that CDRs of the present disclosure necessarily correspond to the Kabat numbering convention.

[0093] The term “Framework” or “FR” residues (or regions) refer to variable domain residues other than the CDR or hypervariable region residues as herein defined. A “human consensus framework” is a framework which represents the most commonly occurring amino acid residue in a selection of human immunoglobulin VL or VH framework sequences.

[0094] As used herein, the term “Percent (%) amino acid sequence identity” with respect to a sequence is defined as the percentage of amino acid residues in a candidate sequence that are identical with the amino acid residues in the specific sequence, after aligning the sequences and introducing gaps, if necessary, to achieve the maximum percent sequence identity, and not considering any conservative substitutions as part of the sequence identity. Alignment for purposes of determining percent amino acid sequence identity can be achieved in various ways that are within the skill in the art, for instance, using publicly available computer software such as EMBOSS MATCHER, EMBOSS WATER, EMBOSS STRETCHER, EMBOSS NEEDLE,

EMBOSS LALIGN, BLAST, BLAST-2, ALIGN or Megalign (DNASTAR) software. Those skilled in the art can determine appropriate parameters for measuring alignment, including any algorithms needed to achieve maximal alignment over the full length of the sequences being compared.

[0095] As used herein, “elimination half-time” is used in its ordinary sense, as is described in Goodman and Gillman's The Pharmaceutical Basis of Therapeutics 21-25 (Alfred Goodman Gilman, Louis S. Goodman, and Alfred Gilman, eds., 6th ed. 1980). Briefly, the term is meant to encompass a quantitative measure of the time course of drug elimination. The elimination of most drugs is exponential (i.e., follows first-order kinetics), since drug concentrations usually do not approach those required for saturation of the elimination process. The rate of an exponential process may be expressed by its rate constant, k, which expresses the fractional change per unit of time, or by its half-time, 11/2 the time required for 50% completion of the process. The units of these two constants are time-1 and time, respectively. A first-order rate constant and the halftime of the reaction are simply related (k*tl/2=0.693) and may be interchanged accordingly.

Since first-order elimination kinetics dictates that a constant fraction of drug is lost per unit time, a plot of the log of drug concentration versus time is linear at all times following the initial distribution phase (i.e. after drug absorption and distribution are complete). The half-time for drug elimination can be accurately determined from such a graph.

[0096] As used herein, the term “binding affinity” refers to the affinity of the proteins described in the disclosure to their binding targets, and is expressed numerically using “Kd” values. If two or more proteins are indicated to have comparable binding affinities towards their binding targets, then the Kd values for binding of the respective proteins towards their binding targets, are within ±2-fold of each other. If two or more proteins are indicated to have comparable binding affinities towards single binding target, then the Kd values for binding of the respective proteins towards said single binding target, are within ±2-fold of each other. If a protein is indicated to bind two or more targets with comparable binding affinities, then the Kd values for binding of said protein to the two or more targets are within ±2-fold of each other. In general, a higher Kd value corresponds to a weaker binding. In some embodiments, the “Kd” is measured by a radiolabeled antigen binding assay (RIA) or surface plasmon resonance assays using a BIAcore™-2000 or a BIAcore™-3000 (BIAcore, Inc., Piscataway, N.J.). In certain embodiments, an “on-rate” or “rate of association” or “association rate” or “kon” and an “offrate” or “rate of dissociation” or “dissociation rate” or “koff ’ are also determined with the surface plasmon resonance technique using a BIAcore™-2000 or a BIAcore™-3000 (BIAcore, Inc., Piscataway, N.J.). In additional embodiments, the “Kd”, “kon”, and “koff’ are measured using the OCTET® Systems (Pall Life Sciences). In an exemplary method for measuring

binding affinity using the OCTET® Systems, the ligand, e.g., biotinylated human or cynomolgus BCMA, is immobilized on the OCTET® streptavidin capillary sensor tip surface which streptavidin tips are then activated according to manufacturer's instructions using about 20-50 qg/ml human or cynomolgus BCMA protein. A solution of PBS/Casein is also introduced as a blocking agent. For association kinetic measurements, BCMA binding protein variants are introduced at a concentration ranging from about 10 ng/mL to about 100 qg/mL, about 50 ng/mL to about 5 pg/mL, or about 2 ng/mL to about 20 pg/mL. In some embodiments, the BCMA binding single domain proteins are used at a concentration ranging from about 2 ng/mL to about 20 pg/mL. Complete dissociation is observed in case of the negative control, assay buffer without the binding proteins. The kinetic parameters of the binding reactions are then determined using an appropriate tool, e.g., ForteBio software.

[0097] The term “about” or “approximately” means within an acceptable error range for the particular value as determined by one of ordinary skill in the art, which will depend in part on how the value is measured or determined, e.g., the limitations of the measurement system. For example, “about” can mean within 1 or more than 1 standard deviation, per the practice in the given value. Where particular values are described in the application and claims, unless otherwise stated the term “about” should be assumed to mean an acceptable error range for the particular value.

[0098] The terms “individual,” “patient,” or “subject” are used interchangeably. None of the terms require or are limited to situations characterized by the supervision (e.g. constant or intermittent) of a health care worker (e.g. a doctor, a registered nurse, a nurse practitioner, a physician’s assistant, an orderly, or a hospice worker).

[0099] The terminology used herein is for the purpose of describing particular cases only and is not intended to be limiting. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, to the extent that the terms “including”, “includes”, “having”, “has”, “with”, or variants thereof are used in either the detailed description and/or the claims, such terms are intended to be inclusive in a manner similar to the term “comprising.”

[00100] In one aspect, the BCMA targeting trispecific proteins comprise a domain (A) which specifically binds to CD3, a domain (B) which specifically binds to human albumin (ALB), and a domain (C) which specifically binds to BCMA. The three domains in BCMA targeting trispecific proteins are arranged in any order. Thus, it is contemplated that the domain order of the BCMA targeting trispecific proteins are:

H2N-(A)-(B)-(C)-COOH, H2N-(A)-(C)-(B)-COOH,

H2N-(B)-(A)-(C)-COOH, H2N-(B)-(C)-(A)-COOH, H2N-(C)-(B)-(A)-COOH, or H2N-(C)-(A)-(B)-COOH.

[00101] In some embodiments, the BCMA targeting trispecific proteins have a domain order of H2N-(A)-(B)-(C)-COOH. In some embodiments, the BCMA targeting trispecific proteins have a domain order of H2N-(A)-(C)-(B)-COOH. In some embodiments, the BCMA targeting trispecific proteins have a domain order of H2N-(B)-(A)-(C)-COOH. In some embodiments, the BCMA targeting trispecific proteins have a domain order of H2N-(B)-(C)-(A)COOH. In some embodiments, the BCMA targeting trispecific proteins have a domain order of H2N-(C)-(B)-(A)-COOH. In some embodiments, the BCMA targeting trispecific proteins have a domain order of H2N-(C)-(A)-(B)-COOH. In some embodiments, the anti-BCMA domain (the anti-target domain, T), the anti-CD3 domain (C), and the anti-ALB domain (A) are in an antiCD3: anti-ALB: anti-BCMA (CAT) orientation. In some embodiments, the anti-BCMA domain (the anti-target domain,T) the anti-CD3 domain (C), and the anti-ALB domain (A) are in an antiBCMA: anti-ALB: anti-CD3 (TAC) orientation.

[00102] In some embodiments, the BCMA targeting trispecific proteins have the HSA binding domain as the middle domain, such that the domain order is H2N-(A)-(B)-(C)-COOH or H2N-(C)-(B)-(A)-COOH. It is contemplated that in such embodiments where the ALB binding domain as the middle domain, the CD3 and BCMA binding domains are afforded additional flexibility to bind to their respective targets.

[00103] In some embodiments, the BCMA targeting trispecific proteins described herein comprise a polypeptide having a sequence described in the Sequence Table (SEQ ID NO: 483597) and subsequences thereof. In some embodiments, the trispecific antigen binding protein comprises a polypeptide having at least 70%-95% or more homology to a sequence described in the Sequence Table (SEQ ID NO: 483-597). In some embodiments, the trispecific antigen binding protein comprises a polypeptide having at least 70%, 75%, 80%, 85%, 90%, 95%, or more homology to a sequence described in the Sequence Table 1 (SEQ ID NO: 483-597).

[00104] The BCMA targeting trispecific proteins described herein are designed to allow specific targeting of cells expressing BCMA by recruiting cytotoxic T cells. This improves efficacy compared to ADCC (antibody dependent cell-mediated cytotoxicity), which is using full length antibodies directed to a sole antigen and is not capable of directly recruiting cytotoxic T cells. In contrast, by engaging CD3 molecules expressed specifically on these cells, the BCMA targeting trispecific proteins can crosslink cytotoxic T cells with cells expressing BCMA in a highly specific fashion, thereby directing the cytotoxic potential of the T cell towards the

target cell. The BCMA targeting trispecific proteins described herein engage cytotoxic T cells via binding to the surface-expressed CD3 proteins, which form part of the TCR. Simultaneous binding of several BCMA trispecific antigen-binding protein to CD3 and to BCMA expressed on the surface of particular cells causes T cell activation and mediates the subsequent lysis of the particular BCMA expressing cell. Thus, BCMA targeting trispecific proteins are contemplated to display strong, specific and efficient target cell killing. In some embodiments, the BCMA targeting trispecific proteins described herein stimulate target cell killing by cytotoxic T cells to eliminate pathogenic cells (e.g., tumor cells expressing BCMA). In some of such embodiments, cells are eliminated selectively, thereby reducing the potential for toxic side effects.

[00105] The BCMA targeting trispecific proteins described herein confer further therapeutic advantages over traditional monoclonal antibodies and other smaller bispecific molecules. Generally, the effectiveness of recombinant protein pharmaceuticals depends heavily on the intrinsic pharmacokinetics of the protein itself. One such benefit here is that the BCMA targeting trispecific proteins described herein have extended pharmacokinetic elimination halftime due to having a half-life extension domain such as a domain specific to HSA. In this respect, the BCMA targeting trispecific proteins described herein have an extended serum elimination half-time of about two, three, about five, about seven, about 10, about 12, or about 14 days in some embodiments. This contrasts to other binding proteins such as BiTE or DART molecules which have relatively much shorter elimination half-times. For example, the BiTE CD19*CD3 bispecific scFv-scFv fusion molecule requires continuous intravenous infusion (i.v.) drug delivery due to its short elimination half-time. The longer intrinsic half-times of the BCMA targeting trispecific proteins solve this issue thereby allowing for increased therapeutic potential such as low-dose pharmaceutical formulations, decreased periodic administration and/or novel pharmaceutical compositions.

[00106] The BCMA targeting trispecific proteins described herein also have an optimal size for enhanced tissue penetration and tissue distribution. Larger sizes limit or prevent penetration or distribution of the protein in the target tissues. The BCMA targeting trispecific proteins described herein avoid this by having a small size that allows enhanced tissue penetration and distribution. Accordingly, the BCMA targeting trispecific proteins described herein, in some embodiments have a size of about 50 kD to about 80 kD, about 50 kD to about 75 kD, about 50 kD to about 70 kD, or about 50 kD to about 65 kD. Thus, the size of the BCMA targeting trispecific proteins is advantageous over IgG antibodies which are about 150 kD and the BiTE and DART diabody molecules which are about 55 kD but are not half-life extended and therefore cleared quickly through the kidney.

[00107] In further embodiments, the BCMA targeting trispecific proteins described herein have an optimal size for enhanced tissue penetration and distribution. In these embodiments, the BCMA targeting trispecific proteins are constructed to be as small as possible, while retaining specificity toward its targets. Accordingly, in these embodiments, the BCMA targeting trispecific proteins described herein have a size of about 20 kD to about 40 kD or about 25 kD to about 35 kD to about 40 kD, to about 45 kD, to about 50 kD, to about 55 kD, to about 60 kD, to about 65 kD. In some embodiments, the BCMA targeting trispecific proteins described herein have a size of about 50kD, 49, kD, 48 kD, 47 kD, 46 kD, 45 kD, 44 kD, 43 kD, 42 kD, 41 kD, 40 kD, about 39 kD, about 38 kD, about 37 kD, about 36 kD, about 35 kD, about 34 kD, about 33 kD, about 32 kD, about 31 kD, about 30 kD, about 29 kD, about 28 kD, about 27 kD, about 26 kD, about 25 kD, about 24 kD, about 23 kD, about 22 kD, about 21 kD, or about 20 kD. An exemplary approach to the small size is through the use of single domain antibody (sdAb) fragments for each of the domains. For example, a particular BCMA trispecific antigen-binding protein has an anti-CD3 sdAb, anti-ALB sdAb and an sdAb for BCMA. This reduces the size of the exemplary BCMA trispecific antigen-binding protein to under 40 kD. Thus in some embodiments, the domains of the BCMA targeting trispecific proteins are all single domain antibody (sdAb) fragments. In other embodiments, the BCMA targeting trispecific proteins described herein comprise small molecule entity (SME) binders for ALB and/or the BCMA.

SME binders are small molecules averaging about 500 to 2000 Da in size and are attached to the BCMA targeting trispecific proteins by known methods, such as sortase ligation or conjugation. In these instances, one of the domains of BCMA trispecific antigen-binding protein is a sortase recognition sequence, e.g., LPETG (SEQ ID NO: 482). To attach a SME binder to BCMA trispecific antigen-binding protein with a sortase recognition sequence, the protein is incubated with a sortase and a SME binder whereby the sortase attaches the SME binder to the recognition sequence. Known SME binders include ΜΠΜ072 and ΜΠΜ095 which bind to BCMA.

[00108] In yet other embodiments, the domain which binds to BCMA of BCMA targeting trispecific proteins described herein comprise a knottin peptide for binding BCMA. Knottins are disulfide-stabilized peptides with a cysteine knot scaffold and have average sizes about 3.5 kD. Knottins have been contemplated for binding to certain tumor molecules such as BCMA. In further embodiments, domain which binds to BCMA of BCMA targeting trispecific proteins described herein comprise a natural BCMA ligand.

[00109] Another feature of the BCMA targeting trispecific proteins described herein is that they are of a single-polypeptide design with flexible linkage of their domains. This allows for facile production and manufacturing of the BCMA targeting trispecific proteins as they can be encoded by single cDNA molecule to be easily incorporated into a vector. Further, because the

BCMA targeting trispecific proteins described herein are a monomeric single polypeptide chain, there are no chain pairing issues or a requirement for dimerization. It is contemplated that the BCMA targeting trispecific proteins described herein have a reduced tendency to aggregate unlike other reported molecules such as bispecific proteins with Fc-gamma immunoglobulin domains.

[00110] In the BCMA targeting trispecific proteins described herein, the domains are linked by internal linkers LI and L2, where LI links the first and second domain of the BCMA targeting trispecific proteins and L2 links the second and third domains of the BCMA targeting trispecific proteins. Linkers LI and L2 have an optimized length and/or amino acid composition. In some embodiments, linkers LI and L2 are the same length and amino acid composition. In other embodiments, LI and L2 are different. In certain embodiments, internal linkers LI and/or L2 are short, i.e., consist of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 or 12 amino acid residues. Thus, in certain instances, the internal linkers consist of about 12 or less amino acid residues. In the case of 0 amino acid residues, the internal linker is a peptide bond. In certain embodiments, internal linkers LI and/or L2 are long, i.e., “consist of’ 15, 20 or 25 amino acid residues. In some embodiments, these internal linkers consist of about 3 to about 15, for example 8, 9 or 10 contiguous amino acid residues. Regarding the amino acid composition of the internal linkers LI and L2, peptides are selected with properties that confer flexibility to the BCMA targeting trispecific proteins, do not interfere with the binding domains as well as resist cleavage from proteases. For example, glycine and serine residues generally provide protease resistance.

Examples of internal linkers suitable for linking the domains in the BCMA targeting trispecific proteins include but are not limited to (GS)n (SEQ ID NO: 472), (GGS)n (SEQ ID NO: 473), (GGGS)n (SEQ ID NO: 474), (GGSG)n (SEQ ID NO: 475), (GGSGG)n (SEQ ID NO: 476), (GGGGS)n (SEQ ID NO: 477), (GGGGG)n (SEQ ID NO: 478), or (GGG)n (SEQ ID NO: 479), wherein n is 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10. In one embodiment, internal linker LI and/or L2 is (GGGGS)4 (SEQ ID NO: 480) or (GGGGS)3 (SEQ ID NO: 481).

CD3 binding domain

[00111] The specificity of the response of T cells is mediated by the recognition of an antigen (displayed in context of a major histocompatibility complex, MHC) by the TCR. As part of the TCR, CD3 is a protein complex that includes a CD3y (gamma) chain, a CD36 (delta) chain, and two CD38 (epsilon) chains which are present on the cell surface. CD3 associates with the a (alpha) and β (beta) chains of the TCR as well as CD3 ζ (zeta) altogether to comprise the complete TCR. Clustering of CD3 on T cells, such as by immobilized anti-CD3 antibodies leads to T cell activation similar to the engagement of the T cell receptor but independent of its clonetypical specificity.

[00112] In one aspect, the BCMA targeting trispecific proteins described herein comprise a domain which specifically binds to CD3. In one aspect, the BCMA targeting trispecific proteins described herein comprise a domain which specifically binds to human CD3. In some embodiments, the BCMA targeting trispecific proteins described herein comprise a domain which specifically binds to CD3y. In some embodiments, the BCMA targeting trispecific proteins described herein comprise a domain which specifically binds to CD36. In some embodiments, the BCMA targeting trispecific proteins described herein comprise a domain which specifically binds to CD38.

[00113] In further embodiments, the BCMA targeting trispecific proteins described herein comprise a domain which specifically binds to the TCR. In certain instances, the BCMA targeting trispecific proteins described herein comprise a domain which specifically binds the a chain of the TCR. In certain instances, the BCMA targeting trispecific proteins described herein comprise a domain which specifically binds the β chain of the TCR.

[00114] In some embodiments, the CD3 binding domain of the BCMA trispecific antigenbinding protein can be any domain that binds to CD3 including but not limited to domains from a monoclonal antibody, a polyclonal antibody, a recombinant antibody, a human antibody, a humanized antibody. In some instances, it is beneficial for the CD3 binding domain to be derived from the same species in which the BCMA trispecific antigen-binding protein will ultimately be used in. For example, for use in humans, it may be beneficial for the CD3 binding domain of the BCMA tri specific antigen-binding protein to comprise human or humanized residues from the antigen binding domain of an antibody or antibody fragment.

[00115] Thus, in one aspect, the anti gen-binding domain comprises a humanized or human antibody or an antibody fragment, or a murine antibody or antibody fragment. In one embodiment, the humanized or human anti-CD3 binding domain comprises one or more (e.g., all three) light chain complementary determining region 1 (LC CDR1), light chain complementary determining region 2 (LC CDR2), and light chain complementary determining region 3 (LC CDR3) of a humanized or human anti- CD3 binding domain described herein, and/or one or more (e.g., all three) heavy chain complementary determining region 1 (HC CDR1), heavy chain complementary determining region 2 (HC CDR2), and heavy chain complementary determining region 3 (HC CDR3) of a humanized or human anti-CD3 binding domain described herein, e.g., a humanized or human anti-CD3 binding domain comprising one or more, e.g., all three, LC CDRs and one or more, e.g., all three, HC CDRs.

[00116] In some embodiments, the humanized or human anti-CD3 binding domain comprises a humanized or human light chain variable region specific to CD3 where the light chain variable region specific to CD3 comprises human or non-human light chain CDRs in a

WO 2019/075359 human light chain framework region. In certain instances, the light chain framework region is a λ (lamda) light chain framework. In other instances, the light chain framework region is a κ (kappa) light chain framework.

[00117] In some embodiments, the humanized or human anti-CD3 binding domain comprises a humanized or human heavy chain variable region specific to CD3 where the heavy chain variable region specific to CD3 comprises human or non-human heavy chain CDRs in a human heavy chain framework region.

[00118] In certain instances, the complementary determining regions of the heavy chain and/or the light chain are derived from known anti-CD3 antibodies, such as, for example, muromonab-CD3 (OKT3), otelixizumab (TRX4), teplizumab (MGA031), visilizumab (Nuvion), SP34, TR-66 or X35-3, VIT3, BMA030 (BW264/56), CLB-T3/3, CRIS7, YTH12.5, Fl 11-409, CLB-T3.4.2, TR-66, WT32, SPv-T3b, 11D8, XIII-141, XIII-46, XIII-87, 12F6, T3/RW2-8C8, T3/RW2-4B6, OKT3D, M-T301, SMC2, F101.01, UCHT-1 and WT-31.

[00119] In one embodiment, the anti-CD3 binding domain is a single chain variable fragment (scFv) comprising a light chain and a heavy chain of an amino acid sequence provided herein. As used herein, single chain variable fragment or scFv refers to an antibody fragment comprising a variable region of a light chain and at least one antibody fragment comprising a variable region of a heavy chain, wherein the light and heavy chain variable regions are contiguously linked via a short flexible polypeptide linker, and capable of being expressed as a single polypeptide chain, and wherein the scFv retains the specificity of the intact antibody from which it is derived. In an embodiment, the anti-CD3 binding domain comprises: a light chain variable region comprising an amino acid sequence having at least one, two or three modifications (e.g., substitutions) but not more than 30, 20 or 10 modifications (e.g., substitutions) of an amino acid sequence of a light chain variable region provided herein, or a sequence with 95-99% identity with an amino acid sequence provided herein; and/or a heavy chain variable region comprising an amino acid sequence having at least one, two or three modifications (e.g., substitutions) but not more than 30, 20 or 10 modifications (e.g., substitutions) of an amino acid sequence of a heavy chain variable region provided herein, or a sequence with 95-99% identity to an amino acid sequence provided herein. In one embodiment, the humanized or human anti-CD3 binding domain is a scFv, and a light chain variable region comprising an amino acid sequence described herein, is attached to a heavy chain variable region comprising an amino acid sequence described herein, via a scFv linker. The light chain variable region and heavy chain variable region of a scFv can be, e.g., in any of the following orientations: light chain variable region- scFv linker-heavy chain variable region or heavy chain variable region- scFv linker-light chain variable region.

[00120] In some instances, scFvs which bind to CD3 are prepared according to known methods. For example, scFv molecules can be produced by linking VH and VL regions together using flexible polypeptide linkers. The scFv molecules comprise a scFv linker (e.g., a Ser-Gly linker) with an optimized length and/or amino acid composition. Accordingly, in some embodiments, the length of the scFv linker is such that the VH or VL domain can associate intermolecularly with the other variable domain to form the CD3 binding site. In certain embodiments, such scFv linkers are short, i.e. consist of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 or 12 amino acid residues. Thus, in certain instances, the scFv linkers consist of about 12 or less amino acid residues. In the case of 0 amino acid residues, the scFv linker is a peptide bond. In some embodiments, these scFv linkers consist of about 3 to about 15, for example 8, 9 or 10 contiguous amino acid residues. Regarding the amino acid composition of the scFv linkers, peptides are selected that confer flexibility, do not interfere with the variable domains as well as allow inter-chain folding to bring the two variable domains together to form a functional CD3 binding site. For example, scFv linkers comprising glycine and serine residues generally provide protease resistance. In some embodiments, linkers in a scFv comprise glycine and serine residues. The amino acid sequence of the scFv linkers can be optimized, for example, by phagedisplay methods to improve the CD3 binding and production yield of the scFv. Examples of peptide scFv linkers suitable for linking a variable light domain and a variable heavy domain in a scFv include but are not limited to (GS)n (SEQ ID NO: 472), (GGS)n (SEQ ID NO: 473), (GGGS)n (SEQ ID NO: 474), (GGSG)n (SEQ ID NO: 475), (GGSGG)n (SEQ ID NO: 476), (GGGGS)n (SEQ ID NO: 477), (GGGGG)n (SEQ ID NO: 478), or (GGG)n(SEQ ID NO: 479), wherein n is 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10. In one embodiment, internal linker LI and/or L2 is (GGGGS)4 (SEQ ID NO: 480) or (GGGGS)3 (SEQ ID NO: 481). Variation in the linker length may retain or enhance activity, giving rise to superior efficacy in activity studies.

[00121] In some embodiments, CD3 binding domain of BCMA trispecific antigen-binding protein has an affinity to CD3 on CD3 expressing cells with a KD of 1000 nM or less, 500 nM or less, 200 nM or less, 100 nM or less, 80 nM or less, 50 nM or less, 20 nM or less, 10 nM or less, 5 nM or less, 1 nM or less, or 0.5 nM or less. In some embodiments, the CD3 binding domain of BCMA trispecific antigen-binding protein has an affinity to CD38, γ, or δ with a KD of 1000 nM or less, 500 nM or less, 200 nM or less, 100 nM or less, 80 nM or less, 50 nM or less, 20 nM or less, 10 nM or less, 5 nM or less, 1 nM or less, or 0.5 nM or less. In further embodiments, CD3 binding domain of BCMA trispecific antigen-binding protein has low affinity to CD3, i.e., about 100 nM or greater.

[00122] The affinity to bind to CD3 can be determined, for example, by the ability of the BCMA trispecific antigen-binding protein itself or its CD3 binding domain to bind to CD3

coated on an assay plate; displayed on a microbial cell surface; in solution; etc. The binding activity of the BCMA tri specific anti gen-binding protein itself or its CD3 binding domain of the present disclosure to CD3 can be assayed by immobilizing the ligand (e.g., CD3) or the BCMA trispecific antigen-binding protein itself or its CD3 binding domain, to a bead, substrate, cell, etc. Agents can be added in an appropriate buffer and the binding partners incubated for a period of time at a given temperature. After washes to remove unbound material, the bound protein can be released with, for example, SDS, buffers with a high pH, and the like and analyzed, for example, by Surface Plasmon Resonance (SPR).

Half-Life extension domain

[00123] Contemplated herein are domains which extend the half-life of an antigen-binding domain. Such domains are contemplated to include but are not limited to Albumin binding domains, Fc domains, small molecules, and other half-life extension domains known in the art. [00124] Human albumin (ALB) (molecular mass of about 67 kDa) is the most abundant protein in plasma, present at about 50 mg/ml (600 μΜ), and has a half-life of around 20 days in humans. ALB serves to maintain plasma pH, contributes to colloidal blood pressure, functions as carrier of many metabolites and fatty acids, and serves as a major drug transport protein in plasma.

[00125] Noncovalent association with albumin extends the elimination half-time of short lived proteins. For example, a recombinant fusion of an albumin binding domain to a Fab fragment resulted in an in vivo clearance of 25- and 58-fold and a half-life extension of 26- and 37-fold when administered intravenously to mice and rabbits respectively as compared to the administration of the Fab fragment alone. In another example, when insulin is acylated with fatty acids to promote association with albumin, a protracted effect was observed when injected subcutaneously in rabbits or pigs. Together, these studies demonstrate a linkage between albumin binding and prolonged action.

[00126] In one aspect, the BCMA targeting trispecific proteins described herein comprise a half-life extension domain, for example a domain which specifically binds to ALB. In some embodiments, the ALB binding domain of BCMA trispecific antigen-binding protein can be any domain that binds to ALB including but not limited to domains from a monoclonal antibody, a polyclonal antibody, a recombinant antibody, a human antibody, a humanized antibody. In some embodiments, the ALB binding domain is a single chain variable fragments (scFv), singledomain antibody such as a heavy chain variable domain (VH), a light chain variable domain (VL) and a variable domain (VHH) of camelid derived single domain antibody, peptide, ligand or small molecule entity specific for HSA. In certain embodiments, the ALB binding domain is a single-domain antibody. In other embodiments, the HSA binding domain is a peptide. In further

embodiments, the HSA binding domain is a small molecule. It is contemplated that the HSA binding domain of BCMA trispecific antigen-binding protein is fairly small and no more than 25 kD, no more than 20 kD, no more than 15 kD, or no more than 10 kD in some embodiments. In certain instances, the ALB binding is 5 kD or less if it is a peptide or small molecule entity. [00127] The half-life extension domain of BCMA trispecific antigen-binding protein provides for altered pharmacodynamics and pharmacokinetics of the BCMA trispecific antigenbinding protein itself. As above, the half-life extension domain extends the elimination halftime. The half-life extension domain also alters pharmacodynamic properties including alteration of tissue distribution, penetration, and diffusion of the trispecific antigen-binding protein. In some embodiments, the half-life extension domain provides for improved tissue (including tumor) targeting, tissue distribution, tissue penetration, diffusion within the tissue, and enhanced efficacy as compared with a protein without a half-life extension domain. In one embodiment, therapeutic methods effectively and efficiently utilize a reduced amount of the trispecific antigenbinding protein, resulting in reduced side effects, such as reduced non-tumor cell cytotoxicity. [00128] Further, the binding affinity of the half-life extension domain can be selected so as to target a specific elimination half-time in a particular trispecific antigen-binding protein. Thus, in some embodiments, the half-life extension domain has a high binding affinity. In other embodiments, the half-life extension domain has a medium binding affinity. In yet other embodiments, the half-life extension domain has a low or marginal binding affinity. Exemplary binding affinities include KD concentrations at 10 nM or less (high), between 10 nM and 100 nM (medium), and greater than 100 nM (low). As above, binding affinities to ALB are determined by known methods such as Surface Plasmon Resonance (SPR).

[00129] In some embodiments, ALB binding domains described herein comprise a single domain antibody.

B Cell Maturation Antigen (BCMA) binding domain

[00130] B cell maturation antigen (BCMA, TNFRSF17, CD269) is a transmembrane protein belonging to the tumor necrosis family receptor (TNFR) super family that is primarily expressed on terminally differentiated B cells. BCMA expression is restricted to the B cell lineage and mainly present on plasma cells and plasmablasts and to some extent on memory B cells, but virtually absent on peripheral and naive B cells. BCMA is also expressed on multiple myeloma (MM) cells, on leukemia cells and lymphoma cells.

[00131] BCMA was identified through molecular analysis of a t(4;16)(q26;pl3) translocation found in a human intestinal T cell lymphoma and an in-frame sequence was mapped to the 16pl3.1 chromosome band.

[00132] Human BCMA cDNA has an open reading frame of 552 bp that encodes a 184 amino acid polypeptide. The BCMA gene is organized into three exons that are separated by two introns, each flanked by GT donor and AG acceptor consensus splicing sites, and codes for a transcript of 1.2 kb. The structure of BCMA protein includes an integral transmembrane protein based on a central 24 amino acid hydrophobic region in an alpha-helix structure.

[00133] The murine BCMA gene is located on chromosome 16 syntenic to the human 16p 13 region, and also includes three exons that are separated by two introns. The gene encodes a 185 amino acid protein. Murine BCMA mRNA is expressed as a 404 bp transcript at the highest levels in plasmacytoma cells (J558) and at modest levels in the A20 B cell lymphoma line. Murine BCMA mRNA transcripts have also been detected at low levels in T cell lymphoma (EL4, BW5147) and dendritic cell (CB1D6, D2SC1) lines in contrast to human cell lines of T cell and dendritic cell origin. The murine BCMA cDNA sequence has 69.3% nucleotide identity with the human BCMA cDNA sequence and slightly higher identity (73.7%) when comparing the coding regions between these two cDNA sequences. Mouse BCMA protein is 62% identical to human BCMA protein and, like human BCMA, contains a single hydrophobic region, which may be an internal transmembrane segment. The N-terminal 40 amino acid domain of both murine and human BCMA protein have six conserved cysteine residues, consistent with the formation of a cysteine repeat motif found in the extracellular domain of TNFRs. Similar to members of the TNFR superfamily, BCMA protein contains a conserved aromatic residue four to six residues C-terminal from the first cysteine.

[00134] BCMA is not expressed at the cell surface, but rather, is located on the Golgi apparatus. The amount of BCMA expression is proportional to the stage of cellular differentiation (highest in plasma cells).

[00135] It is involved in B cell development and homeostasis due to its interaction with its ligands BAFF (B cell activating factor, also designated as TALL-1 or TNFSF13B) and APRIL (A proliferation inducing ligand).

[00136] BCMA regulates different aspects of humoral immunity, B cell development and homeostasis along with its family members TACI (transmembrane activator and cyclophylin ligand interactor) and BAFF-R (B cell activation factor receptor, also known as tumor necrosis factor receptor superfamily member 13C). Expression of BCMA appears rather late in B cell differentiation and contributes to the long term survival of plasmablasts and plasma cells in the bone marrow. BCMA also supports growth and survival of multiple myeloma (MM) cells.

[00137] BCMA is mostly known for its functional activity in mediating the survival of plasma cells that maintain long-term humoral immunity.

[00138] There is a need for having treatment options for solid tumor diseases related to the overexpression of BCMA, such as cancer multiple myeloma, leukemias and lymphomas. The present disclosure provides, in certain embodiments, single domain proteins which specifically bind to BCMA on the surface of tumor target cells.

[00139] The design of the BCMA targeting trispecific proteins described herein allows the binding domain to BCMA to be flexible in that the binding domain to BCMA can be any type of binding domain, including but not limited to, domains from a monoclonal antibody, a polyclonal antibody, a recombinant antibody, a human antibody, a humanized antibody. In some embodiments, the binding domain to BCMA is a single chain variable fragments (scFv), singledomain antibody such as a heavy chain variable domain (VH), a light chain variable domain (VL) and a variable domain (VHH) of camelid derived single domain antibody. In other embodiments, the binding domain to BCMA is a non-Ig binding domain, i.e., antibody mimetic, such as anticalins, affilins, affibody molecules, afflmers, affitins, alphabodies, avimers, DARPins, fynomers, kunitz domain peptides, and monobodies. In further embodiments, the binding domain to BCMA is a ligand or peptide that binds to or associates with BCMA. In yet further embodiments, the binding domain to BCMA is a knottin. In yet further embodiments, the binding domain to BCMA is a small molecular entity.

[00140] In some embodiments, the BCMA binding domain binds to a protein comprising the sequence of SEQ ID NO: 469, 470 or 471. In some embodiments, the BCMA binding domain binds to a protein comprising a truncated sequence compared to SEQ ID NO: 469, 470 or 471. [00141] In some embodiments, the BCMA binding domain is an anti-BCMA antibody or an antibody variant. As used herein, the term antibody variant refers to variants and derivatives of an antibody described herein. In certain embodiments, amino acid sequence variants of the anti-BCMA antibodies described herein are contemplated. For example, in certain embodiments amino acid sequence variants of anti-BCMA antibodies described herein are contemplated to improve the binding affinity and/or other biological properties of the antibodies. Exemplary method for preparing amino acid variants include, but are not limited to, introducing appropriate modifications into the nucleotide sequence encoding the antibody, or by peptide synthesis. Such modifications include, for example, deletions from, and/or insertions into and/or substitutions of residues within the amino acid sequences of the antibody.

[00142] Any combination of deletion, insertion, and substitution can be made to arrive at the final construct, provided that the final construct possesses the desired characteristics, e.g., antigen- binding. In certain embodiments, antibody variants having one or more amino acid substitutions are provided. Sites of interest for substitution mutagenesis include the CDRs and framework regions. Examples of such substitutions are described below. Amino acid

substitutions may be introduced into an antibody of interest and the products screened for a desired activity, e.g., retained/improved antigen binding, decreased immunogenicity, or improved T-cell mediated cytotoxicity (TDCC). Both conservative and non-conservative amino acid substitutions are contemplated for preparing the antibody variants.

[00143] In another example of a substitution to create a variant anti-BCMA antibody, one or more hypervariable region residues of a parent antibody are substituted. In general, variants are then selected based on improvements in desired properties compared to a parent antibody, for example, increased affinity, reduced affinity, reduced immunogenicity, increased pH dependence of binding.

[00144] In some embodiments, the BCMA binding domain of the BCMA targeting trispecific protein is a single domain antibody such as a heavy chain variable domain (VH), a variable domain (VHH) of a llama derived sdAb, a peptide, a ligand or a small molecule entity specific for BCMA. In some embodiments, the BCMA binding domain of the BCMA targeting trispecific protein described herein is any domain that binds to BCMA including but not limited to domains from a monoclonal antibody, a polyclonal antibody, a recombinant antibody, a human antibody, a humanized antibody. In certain embodiments, the BCMA binding domain is a singledomain antibody. In other embodiments, the BCMA binding domain is a peptide. In further embodiments, the BCMA binding domain is a small molecule.

[00145] Generally, it should be noted that the term single domain antibody as used herein in its broadest sense is not limited to a specific biological source or to a specific method of preparation. Single domain antibodies are antibodies whose complementary determining regions are part of a single domain polypeptide. Examples include, but are not limited to, heavy chain antibodies, antibodies naturally devoid of light chains, single domain antibodies derived from conventional 4-chain antibodies, engineered antibodies and single domain scaffolds other than those derived from antibodies. Single domain antibodies may be any of the art, or any future single domain antibodies. Single domain antibodies may be derived from any species including, but not limited to mouse, human, camel, llama, goat, rabbit, bovine. For example, in some embodiments, the single domain antibodies of the disclosure are obtained: (1) by isolating the VHH domain of a naturally occurring heavy chain antibody; (2) by expression of a nucleotide sequence encoding a naturally occurring VHH domain; (3) by humanization of a naturally occurring VHH domain or by expression of a nucleic acid encoding a such humanized VHH domain; (4) by camelization of a naturally occurring VH domain from any animal species, and in particular from a species of mammal, such as from a human being, or by expression of a nucleic acid encoding such a camelized VH domain; (5) by camelisation of a domain antibody or Dab, or by expression of a nucleic acid encoding such a camelized VH domain;

(6) by using synthetic or semi-synthetic techniques for preparing proteins, polypeptides or other amino acid sequences; (7) by preparing a nucleic acid encoding a single domain antibody using techniques for nucleic acid synthesis known in the field, followed by expression of the nucleic acid thus obtained; and/or (8) by any combination of one or more of the foregoing.

[00146] In one embodiment, a single domain antibody corresponds to the VHH domains of naturally occurring heavy chain antibodies directed against BCMA. As further described herein, such VHH sequences can generally be generated or obtained by suitably immunizing a species of Llama with BCMA, (i.e., so as to raise an immune response and/or heavy chain antibodies directed against BCMA), by obtaining a suitable biological sample from said Llama (such as a blood sample, serum sample or sample of B-cells), and by generating VHH sequences directed against BCMA, starting from said sample, using any suitable technique known in the field.

[00147] In another embodiment, such naturally occurring VHH domains against BCMA, are obtained from naive libraries of Camelid VHH sequences, for example by screening such a library using BCMA, or at least one part, fragment, antigenic determinant or epitope thereof using one or more screening techniques known in the field. Such libraries and techniques are for example described in WO 99/37681, WO 01/90190, WO 03/025020 and WO 03/035694. Alternatively, improved synthetic or semi-synthetic libraries derived from naive VHH libraries are used, such as VHH libraries obtained from naive VHH libraries by techniques such as random mutagenesis and/or CDR shuffling, as for example described in WO 00/43507.

[00148] In a further embodiment, yet another technique for obtaining VHH sequences directed against BCMA, involves suitably immunizing a transgenic mammal that is capable of expressing heavy chain antibodies (i.e., so as to raise an immune response and/or heavy chain antibodies directed against BCMA), obtaining a suitable biological sample from said transgenic mammal (such as a blood sample, serum sample or sample of B-cells), and then generating VHH sequences directed against BCMA, starting from said sample, using any suitable technique known in the field. For example, for this purpose, the heavy chain antibody-expressing rats or mice and the further methods and techniques described in WO 02/085945 and in WO 04/049794 can be used.

[00149] In some embodiments, an anti-BCMA single domain antibody of the BCMA targeting trispecific protein comprises a single domain antibody with an amino acid sequence that corresponds to the amino acid sequence of a naturally occurring VHH domain, but that has been humanized, i.e., by replacing one or more amino acid residues in the amino acid sequence of said naturally occurring VHH sequence (and in particular in the framework sequences) by one or more of the amino acid residues that occur at the corresponding position(s) in a VH domain from a conventional 4-chain antibody from a human being (e.g., as indicated above). This can be

performed in a manner known in the field, which will be clear to the skilled person, for example on the basis of the further description herein. Again, it should be noted that such humanized antiBCMA single domain antibodies of the disclosure are obtained in any suitable manner known per se (i.e., as indicated under points (1)-(8) above) and thus are not strictly limited to polypeptides that have been obtained using a polypeptide that comprises a naturally occurring VHH domain as a starting material. In some additional embodiments, a single domain anti-BCMA antibody, as described herein, comprises a single domain antibody with an amino acid sequence that corresponds to the amino acid sequence of a naturally occurring VH domain, but that has been camelized, i.e., by replacing one or more amino acid residues in the amino acid sequence of a naturally occurring VH domain from a conventional 4-chain antibody by one or more of the amino acid residues that occur at the corresponding position(s) in a VHH domain of a heavy chain antibody. Such camelizing substitutions are preferably inserted at amino acid positions that form and/or are present at the VH-VL interface, and/or at the so-called Camelidae hallmark residues (see for example WO 94/04678 and Davies and Riechmann (1994 and 1996)).

Preferably, the VH sequence that is used as a starting material or starting point for generating or designing the camelized single domain is preferably a VH sequence from a mammal, more preferably the VH sequence of a human being, such as a VH3 sequence. However, it should be noted that such camelized anti-BCMA single domain antibodies of the disclosure, in certain embodiments, are obtained in any suitable manner known in the field (i.e., as indicated under points (1)-(8) above) and thus are not strictly limited to polypeptides that have been obtained using a polypeptide that comprises a naturally occurring VH domain as a starting material. For example, as further described herein, both humanization and camelization is performed by providing a nucleotide sequence that encodes a naturally occurring VHH domain or VH domain, respectively, and then changing, one or more codons in said nucleotide sequence in such a way that the new nucleotide sequence encodes a humanized or camelized single domain antibody, respectively. This nucleic acid can then be expressed, so as to provide a desired anti-BCMA single domain antibody of the disclosure. Alternatively, in other embodiments, based on the amino acid sequence of a naturally occurring VHH domain or VH domain, respectively, the amino acid sequence of the desired humanized or camelized anti-BCMA single domain antibody of the disclosure, respectively, are designed and then synthesized de novo using known techniques for peptide synthesis. In some embodiments, based on the amino acid sequence or nucleotide sequence of a naturally occurring VHH domain or VH domain, respectively, a nucleotide sequence encoding the desired humanized or camelized anti-BCMA single domain antibody of the disclosure, respectively, is designed and then synthesized de novo using known techniques for nucleic acid synthesis, after which the nucleic acid thus obtained is expressed in

using known expression techniques, so as to provide the desired anti-BCMA single domain antibody of the disclosure.

[00150] Other suitable methods and techniques for obtaining the anti-BCMA single domain antibody of the disclosure and/or nucleic acids encoding the same, starting from naturally occurring VH sequences or VHH sequences for example comprises combining one or more parts of one or more naturally occurring VH sequences (such as one or more framework (FR) sequences and/or complementarity determining region (CDR) sequences), one or more parts of one or more naturally occurring VHH sequences (such as one or more FR sequences or CDR sequences), and/or one or more synthetic or semi-synthetic sequences, in a suitable manner, so as to provide an anti-BCMA single domain antibody of the disclosure or a nucleotide sequence or nucleic acid encoding the same.

[00151] In some embodiments, the BCMA binding domain is an anti-BCMA specific antibody comprising a heavy chain variable complementarity determining region CDR1, a heavy chain variable CDR2, a heavy chain variable CDR3, a light chain variable CDR1, a light chain variable CDR2, and a light chain variable CDR3. In some embodiments, the BCMA binding domain comprises any domain that binds to BCMA including but not limited to domains from a monoclonal antibody, a polyclonal antibody, a recombinant antibody, a human antibody, a humanized antibody, or antigen binding fragments such as single domain antibodies (sdAb), Fab, Fab', F(ab)2, and Fv fragments, fragments comprised of one or more CDRs, single-chain antibodies (e.g., single chain Fv fragments (scFv)), disulfide stabilized (dsFv) Fv fragments, heteroconjugate antibodies (e.g., bispecific antibodies), pFv fragments, heavy chain monomers or dimers, light chain monomers or dimers, and dimers consisting of one heavy chain and one light chain. In some embodiments, the BCMA binding domain is a single domain antibody. In some embodiments, the anti-BCMA single domain antibody comprises heavy chain variable complementarity determining regions (CDR), CDR1, CDR2, and CDR3.

[00152] In some embodiments, the BCMA binding protein of the present disclosure is a polypeptide comprising an amino acid sequence that is comprised of four framework regions/sequences (fl-f4) interrupted by three complementarity determining regions/sequences, as represented by the formula: fl-rl-f2-r2-f3-r3-f4, wherein rl, r2, and r3 are complementarity determining regions CDR1, CDR2, and CDR3, respectively, and fl, f2, f3, and f4 are framework residues. The rl residues of the BCMA binding protein of the present disclosure comprise, for example, amino acid residues 26, 27, 28, 29, 30, 31, 32, 33 and 34; the r2 residues of the BCMA binding protein of the present disclosure comprise, for example, amino acid residues, for example, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59,60, 61, 62 and 63; and the r3 residues of the BCMA binding protein of the present disclosure comprise, for example, amino acid residues, for

example, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107 and 108. In some embodiments, the BCMA binding protein comprises an amino acid sequence selected from SEQ ID NOs: 346-460.

Vectors of particular interest include plasmids, phagemids, phage derivatives, virii (e.g., retroviruses, adenoviruses, adeno-associated viruses, herpes viruses, lentiviruses, and the like), and cosmids.

[00194] A variety of expression vector/host systems may be utilized to contain and express the polynucleotide encoding the polypeptide of the described trispecific antigen-binding protein. Examples of expression vectors for expression in E.coli are pSKK (Le Gall et al., J

Immunol Methods. (2004) 285(1): 111-27) or pcDNA5 (Invitrogen) for expression in mammalian cells.

[00195] Thus, the BCMA targeting trispecific proteins as described herein, in some embodiments, are produced by introducing a vector encoding the protein as described above into a host cell and culturing said host cell under conditions whereby the protein domains are expressed, may be isolated and, optionally, further purified.

Integration into chimeric antigen receptors (CAR)

[00196] The BCMA targeting trispecific antigen binding proteins of the present disclosure can, in certain examples, be incorporated into a chimeric antigen receptor (CAR). An engineered immune effector cell, e.g., a T cell or NK cell, can be used to express a CAR that includes an anti-BCMA targeting trispecific protein containing an anti-BCMA single domain antibody as described herein. In one embodiment, the CAR including an anti-BCMA targeting trispecific protein as described herein is connected to a transmembrane domain via a hinge region, and further a costimulatory domain, e.g., a functional signaling domain obtained from 0X40, CD27, CD28, CD5, ICAM-1, LFA-1 (CD1 la/CD18), ICOS (CD278), 0r4-lBB. In some embodiments, the CAR further comprises a sequence encoding a intracellular signaling domain, such as 4-IBB and/or CD3 zeta.

[00217] In some embodiments, the anti-BCMA targeting trispecific protein as described herein is administered before, during, or after surgery.

[00218] In some embodiments, the anti-cancer agent is conjugated via any suitable means to the trispecific protein.

Methods of Detection of BCMA Expression and Diagnosis of BCMA Associated Cancer [00219] According to another embodiment of the disclosure, kits for detecting expression of BCMA in vitro and/or in vivo are provided. The kits include the foregoing BCMA targeting trispecific proteins (e.g., a trispecific protein containing a labeled anti-BCMA single domain antibody or antigen binding fragments thereof), and one or more compounds for detecting the label. In some embodiments, the label is selected from the group consisting of a fluorescent label, an enzyme label, a radioactive label, a nuclear magnetic resonance active label, a luminescent label, and a chromophore label.

[00220] In some cases, BCMA expression is detected in a biological sample. The sample can be any sample, including, but not limited to, tissue from biopsies, autopsies and pathology specimens. Biological samples also include sections of tissues, for example, frozen sections taken for histological purposes. Biological samples further include body fluids, such as blood, serum, plasma, sputum, spinal fluid or urine. A biological sample is typically obtained from a mammal, such as a human or non-human primate.

[00221] Samples to be obtained for use in an assay described herein include tissues and bodily fluids may be processed using conventional means in the art (e.g., homogenization, serum isolation, etc). Accordingly, a sample obtained from a patient is transformed prior to use in an assay described herein. BCMA, if present in the sample, is further transformed in the methods described herein by virtue of binding to, for example, an antibody.

[00222] In one embodiment, provided is a method of determining if a subject has cancer by contacting a sample from the subject with an anti-BCMA single domain antibody as disclosed herein; and detecting binding of the single domain antibody to the sample. An increase in binding of the antibody to the sample as compared to binding of the antibody to a control sample identifies the subject as having cancer.

[00223] In another embodiment, provided is a method of confirming a diagnosis of cancer in a subject by contacting a sample from a subject diagnosed with cancer with an antiBCMA single domain antibody as disclosed herein; and detecting binding of the antibody to the sample. An increase in binding of the antibody to the sample as compared to binding of the antibody to a control sample confirms the diagnosis of cancer in the subject.

[00224] In some examples of the disclosed methods, the BCMA single domain antibody of the trispecific protein is directly labeled.

[00225] In some examples, the methods further include contacting a second antibody that specifically binds the anti-BCMA single domain antibody with the sample; and detecting the binding of the second antibody. An increase in binding of the second antibody to the sample as compared to binding of the second antibody to a control sample detects cancer in the subject or confirms the diagnosis of cancer in the subject.

[00226] In some cases, the cancer is a leukemia, a lymphoma, a multiple myeloma, or any other type of cancer that expresses BCMA.

[00227] In some examples, the control sample is a sample from a subject without cancer. In particular examples, the sample is a blood or tissue sample.

[00228] In some cases, the antibody that binds (for example specifically binds) BCMA is directly labeled with a detectable label. In another embodiment, the antibody that binds (for example, specifically binds) BCMA (the first antibody) is unlabeled and a second antibody or

other molecule that can bind the antibody that specifically binds BCMA is labeled. A second antibody is chosen such that it is able to specifically bind the specific species and class of the first antibody. For example, if the first antibody is a llama IgG, then the secondary antibody may be an anti-llama-IgG. Other molecules that can bind to antibodies include, without limitation, Protein A and Protein G, both of which are available commercially. Suitable labels for the antibody or secondary antibody are described above, and include various enzymes, prosthetic groups, fluorescent materials, luminescent materials, magnetic agents and radioactive materials. Non-limiting examples of suitable enzymes include horseradish peroxidase, alkaline phosphatase, beta-galactosidase, or acetylcholinesterase. Non-limiting examples of suitable prosthetic group complexes include streptavidin/biotin and avidin/biotin. Non-limiting examples of suitable fluorescent materials include umbelliferone, fluorescein, fluorescein isothiocyanate, rhodamine, dichlorotriazinylamine fluorescein, dansyl chloride or phycoerythrin. A non-limiting exemplary luminescent material is luminol; a non-limiting exemplary a magnetic agent is gadolinium, and non-limiting exemplary radioactive labels include 1251, 1311, 35S or 3H.

[00229] In an alternative embodiment, BCMA can be assayed in a biological sample by a competition immunoassay utilizing BCMA standards labeled with a detectable substance and an unlabeled antibody that specifically binds BCMA. In this assay, the biological sample, the labeled BCMA standards and the antibody that specifically bind BCMA are combined and the amount of labeled BCMA standard bound to the unlabeled antibody is determined. The amount of BCMA in the biological sample is inversely proportional to the amount of labeled BCMA standard bound to the antibody that specifically binds BCMA.

[00230] The immunoassays and method disclosed herein can be used for a number of purposes. In one embodiment, the antibody that specifically binds BCMA may be used to detect the production of BCMA in cells in cell culture. In another embodiment, the antibody can be used to detect the amount of BCMA in a biological sample, such as a tissue sample, or a blood or serum sample. In some examples, the BCMA is cell-surface BCMA. In other examples, the BCMA is soluble BCMA (e.g., BCMA in a cell culture supernatant or soluble BCMA in a body fluid sample, such as a blood or serum sample).

[00231] In one embodiment, a kit is provided for detecting BCMA in a biological sample, such as a blood sample or tissue sample. For example, to confirm a cancer diagnosis in a subject, a biopsy can be performed to obtain a tissue sample for histological examination.

Alternatively, a blood sample can be obtained to detect the presence of soluble BCMA protein or fragment. Kits for detecting a polypeptide will typically comprise a single domain antibody, according to the present disclosure, that specifically binds BCMA. In some embodiments, an antibody fragment, such as a scFv fragment, a VH domain, or a Fab is included in the kit. In a

further embodiment, the antibody is labeled (for example, with a fluorescent, radioactive, or an enzymatic label).

[00232] In one embodiment, a kit includes instructional materials disclosing means of use of an antibody that binds BCMA. The instructional materials may be written, in an electronic form (such as a computer diskette or compact disk) or may be visual (such as video files), or provided through an electronic network, for example, over the internet, World Wide Web, an intranet, or other network. The kits may also include additional components to facilitate the particular application for which the kit is designed. Thus, for example, the kit may additionally contain means of detecting a label (such as enzyme substrates for enzymatic labels, filter sets to detect fluorescent labels, appropriate secondary labels such as a secondary antibody, or the like). The kits may additionally include buffers and other reagents routinely used for the practice of a particular method. Such kits and appropriate contents are well known to those of skill in the art. [00233] In one embodiment, the diagnostic kit comprises an immunoassay. Although the details of the immunoassays may vary with the particular format employed, the method of detecting BCMA in a biological sample generally includes the steps of contacting the biological sample with an antibody which specifically reacts, under immunologically reactive conditions, to a BCMA polypeptide. The antibody is allowed to specifically bind under immunologically reactive conditions to form an immune complex, and the presence of the immune complex (bound antibody) is detected directly or indirectly.

[00234] Methods of determining the presence or absence of a cell surface marker are well known in the art. For example, the antibodies can be conjugated to other compounds including, but not limited to, enzymes, magnetic beads, colloidal magnetic beads, haptens, fluorochromes, metal compounds, radioactive compounds or drugs. The antibodies can also be utilized in immunoassays such as but not limited to radioimmunoassays (RIAs), ELISA, or immunohistochemical assays. The antibodies can also be used for fluorescence activated cell sorting (FACS). FACS employs a plurality of color channels, low angle and obtuse lightscattering detection channels, and impedance channels, among other more sophisticated levels of detection, to separate or sort cells (see U.S. Patent No. 5, 061,620). Any of the single domain antibodies that bind BCMA, as disclosed herein, can be used in these assays. Thus, the antibodies can be used in a conventional immunoassay, including, without limitation, an ELISA, an RIA, FACS, tissue immunohistochemistry, Western blot or immunoprecipitation.

EXAMPLES

[00235] The application may be better understood by reference to the following nonlimiting examples, which are provided as exemplary embodiments of the application. The

following examples are presented in order to more fully illustrate embodiments and should in no way be construed, however, as limiting the broad scope of the application.

Example 1

[00236] Protein Production

[00237] Sequences of BCMA targeting trispecific molecules, containing a BCMA binding protein according to the present disclosure, were cloned into mammalian expression vector pcDNA 3.4 (Invitrogen) preceded by a leader sequence and followed by a 6x Histidine Tag (SEQ ID NO: 471). Expi293 cells (Life Technologies A14527) were maintained in suspension in Optimum Growth Flasks (Thomson) between 0.2 to 8 x le6 cells/mL in Expi293 media. Purified plasmid DNA was transfected into Expi293 cells in accordance with Expi293 Expression System Kit (Life Technologies, A14635) protocols, and maintained for 4-6 days post transfection. The amount of the exemplary trispecific proteins being tested, in the conditioned media, from the transfected Expi293 cells was quantitated using an Octet instrument with Protein A tips and using a control trispecific protein for a standard curve.

[00238] T cell dependent cellular cytotoxicity assays

[00239] Titrations of conditioned media was added to TDCC assays (T cell Dependent Cell Cytotoxicity assays) to assess whether the anti-BCMA single domain antibody is capable of forming a synapse between T cells and a BCMA-expressing cell line and direct the T cells to kill the BCMA-expressing cell line. In this assay (Nazarian etal., 2015. J. BiomoL Screen., 20:51927), T cells and target cancer cell line cells were mixed together at a 10:1 ratio in a 384-well plate, and varying amounts of the trispecific proteins being tested were added. The tumor cell lines were engineered to express luciferase protein. After 48 hours, to quantitate the remaining viable tumor cells, STEADY-GLO® Luminescent Assay (Promega) was used.

[00240] In this example EJM cells were used, which is a cell line that serves as an in vitro model for multiple myeloma and plasma cell leukemia. Viability of the EJM cells is measured after 48 hours. It was seen that the trispecific proteins mediated T cell killing. Fig. 2 shows an example cell viability assay with test proteins 01H08, 01F07, 02F02 and BH253 compared to a negative control. The EC50 for the TDCC activity of several other test trispecific proteins are listed below in Table 1.

Example

Methods to assess binding and cytotoxic activities of exemplary BCMA targeting trispecific proteins according to the present disclosure against Jekol, MOLP8 and OPM2 cells [00248] Protein Production

[00249] Sequences of BCMA targeting trispecific molecules, containing a BCMA binding protein according to the present disclosure, preceded by a leader sequence and followed by a 6x Histidine Tag (SEQ ID NO: 471), were expressed using the vectors and methods previously described (Running Deer and Allison, 2004. BiotechnolProg. 20:880-9) except lipid based reagents and non-linearized plasmid DNA were used for cell transfection. Recombinant trispecific proteins were purified using affinity chromatography, ion exchange, and/or size exclusion chromatography. Purified protein was quantitated using theoretical extinction coefficients and absorption spectroscopy. An image of a Coomassie stained SDS-PAGE demonstrates the purity of the proteins (Fig. 3).

[00250] Cytotoxicity assays

[00251] A human T-cell dependent cellular cytotoxicity (TDCC) assay was used to measure the ability of T cell engagers, including trispecific molecules, to direct T cells to kill tumor cells (Nazarian et al., 2015. J. BiomoL Screen., 20:519-27). In this assay, T cells and target cancer cell line cells are mixed together at a 10:1 ratio in a 384-well plate, and varying amounts of the trispecific proteins being tested are added. The tumor cell lines are engineered to express luciferase protein. After 48 hours, to quantitate the remaining viable tumor cells, Steady-Gio® Luminescent Assay (Promega) was used.

[00252] In the instant study, titrations of purified protein were added to TDCC assays (T cell Dependent Cell Cytotoxicity assays) to assess whether the anti-BCMA single domain antibody was capable of forming a synapse between T cells and BCMA-expressing Jekol, MOLP8 and 0PM2 cancer cell lines. Jekol is a B cell lymphoma cell line. MOLP-8 is a myeloma cell line. OPM-2 is a human myeloma cell line.

[00253] Viability of the cells was measured after 48 hours. It was seen that the trispecific proteins mediated T cell killing. Fig. 4 shows an example cell viability assay with test proteins compared to a negative control. The EC50 for the TDCC activity of several other test trispecific

proteins are listed below in Table 2. An anti-GFP trispecific molecule, included in these assays as a negative control, had no effect on cell viability (data not shown).

[00255] Binding affinity

[00256] In the instant study, the binding affinity to human BCMA protein of the BCMA targeting trispecific proteins containing a BCMA binding protein according to the present disclosure was determined.

[00258] The data in Fig. 3, Fig. 4, Table 2 and Table 3 indicate the BCMA targeting trispecific proteins can be expressed and purified to greater than 90% purity. The purified proteins exhibit about 13 fold to 213 fold more potent TDCC activity compared to a trispecific protein with the parent BCMA targeting sequence. The purified trispecific proteins bind to BCMA with affinity of about 3 to 7 nM.

Example

Xenograft tumor model

[00259] An exemplary BCMA targeting trispecific protein described herein was evaluated in a xenograft model.

[00260] On day 0, NCG mice were subcutaneously inoculated with RPMI-8226 cells, and also intraperitoneally implanted with normal human peripheral blood mononuclear cells (PBMCs). Treatment with an exemplary BCMA targeting trispecific protein (02B05) (SEQ ID NO: 520) was also started on day 0 (qdxlO) (once daily for 10 days). The dosage of administration was 5 gg/kg, 50 gg/kg, or 500 gg/kg of the BCMA targeting trispecific protein 02B05, or a vehicle as control. Tumor volumes were determined for 25 days. As shown in Fig. 30, the mean tumor volumes were significantly lower in mice treated with the exemplary BCMA targeting trispecific protein (02B05) (at 50 gg/kg, or 500 gg/kg), as compared to the mice treated with the vehicle or the lower dose of BCMA targeting trispecific protein (02B05) (at 5 gg/kg). [00261] On day 0, NCG mice were subcutaneously inoculated with Jeko 1 cells, and also intraperitoneally implanted with normal human peripheral blood mononuclear cells (PBMCs). Treatment with an exemplary BCMA targeting trispecific protein (02B05) (SEQ ID NO: 520) was started on day 3 (qdxlO) (once daily for 10 days). The dosage of administration was 5 gg/kg, 50 gg/kg, or 500 gg/kg of the BCMA targeting trispecific protein 02B05, or a vehicle as control. Tumor volumes were determined for 25 days. As shown in Fig. 31, the mean tumor volumes were significantly lower in mice treated with the exemplary BCMA targeting trispecific protein (02B05) (at 500 gg/kg), as compared to the mice treated with the vehicle or the lower doses of BCMA targeting trispecific protein (02B05) (at 5 gg/kg or 50 gg/kg).

Affinity Measurements for human and cynomolgus BCMA, CD3e, and albumin, using an exemplary BCMA targeting trispecific protein of this disclosure

[00283] The aim of this study was to assess the affinity of an exemplary BCMA targeting trispecific protein of this disclosure (02B05) (SEQ ID NO: 520), toward human BCMA, cynomolgus BCMA, human CD38, cynomolgus CD38, human albumin, cynomolgus albumin, and mouse albumin. The affinities were measured using an Octet instrument. For these measurements, streptavidin tips were first loaded with 2.5 nM human BCMA-Fc, 2.5 nM cynomologus BCMA-Fc, 2.5 nM human CD38-Fc, 2.5 nM cynomolgus CD38-Fc, 50 nM human serum albumin (HSA), 50 nM cynomolgus serum albumin, or 50 nM mouse serum albumin. Subsequently, the exemplary BCMA targeting trispecific protein 02B05 was incubated with the tips, and following an association period, the tips were moved to a buffer solution to allow the exemplary BCMA targeting trispecific protein (02B05) to disassociate. The affinities for binding to human and cynomolgus BCMA and CD38 were measured in the presence of 15 mg/ml human serum albumin. Average calculated KD values from these studies are provided in Table 4 (n indicates the number of independent measurements, n/d indicates no binding detected under the conditions tested). Binding was detected to human BCMA, human CD38, cynomolgus CD38, human serum albumin, cynomolgus serum albumin, and mouse serum albumin. Under the conditions tested, no binding was detected to cynomolgus BCMA.

Human T cell binding ability of an exemplary BCMA targeting trispecific protein of this disclosure

[00285] Exemplary BCMA targeting trispecific protein 02B05 (SEQ ID NO: 520) was tested for its ability to bind to purified T cells. Briefly, the BCMA trispecific protein or phosphate buffered saline (PBS) were incubated with purified T cells from 4 different anonymous human donors. After washing unbound protein, the T cells were then incubated with an Alexa Fluor 647 conjugated antibody that recognizes the anti-albumin domain in the 02B05 BCMA trispecific antigen-binding protein. The T cells were then analyzed by flow cytometry. It was observed that human T cells incubated with the 02B05 BCMA trispecific antigen-binding protein had notable shifts associated with Alexa Fluor 647 staining compared to cells that were incubated with PBS. The results are shown in Figs. 5A, 5B, 5C, and 5D. In conclusion, this study indicated that the exemplary BCMA targeting trispecific protein was able to bind human T cells.

Example

Ability of an exemplary BCMA targeting trispecific protein of this disclosure to bind BCMA expressing cells

[00286] Exemplary BCMA targeting trispecific protein 02B05 (SEQ ID NO: 520) was tested for its ability to bind to BCMA expressing cells. Briefly, the 02B05 BCMA trispecific

antigen-binding protein was incubated with cell lines expressing BCMA (NCI-H929; EJM; RPMI-8226; OPM2) or lacking BCMA (NCI-H510A; DMS-153). Expression of BCMA RNA in these cells is indicated by the FPKM (fragments per kilobase million) values listed in Figs. 6A-F: the RNA FPKM values are from the Cancer Cell Line Encyclopedia (Broad Institute, Cambridge, MA USA). After washing unbound protein, the cells were then incubated with an Alexa Fluor 647 conjugated antibody that recognizes the anti-albumin domain in the 02B05 BCMA trispecific antigen-binding protein. The cells were then analyzed by flow cytometry. As a negative control, cells were incubated with a trispecific protein targeting GFP. Cells expressing BCMA RNA and incubated with the BCMA trispecific protein had notable shifts associated with Alexa Fluor 647 staining compared to cells that were incubated with GFP trispecific protein (as in Figs. 6A, 6B, 6D, and 6E). Whereas, cells lacking BCMA RNA produced equivalent Alexa Fluor 647 staining with the BCMA trispecific protein and the GFP trispecific protein (as seen in Figs. 6C, and 6F). Thus, this study indicated that the exemplary BCMA trispecific antigen-binding was able to selectively bind to cells expressing BCMA.

Example

Ability of an exemplary BCMA targeting trispecific protein to mediate T cell killing of cancer cells expressing BCMA

[00287] Exemplary BCMA trispecific protein 02B05 (SEQ ID NO: 520) was tested for its ability to direct T cells to kill BCMA expressing cells in the presence and absence of human serum albumin (HSA) using a standard TDCC assay as described in Example 1. Because the exemplary BCMA trispecific protein contains an anti-albumin domain, this experiment was performed to confirm that binding to albumin would not prevent the BCMA trispecific antigenbinding protein from directing T cells to kill BCMA expressing cells. Five BCMA expressing cell lines were tested: EJM, Jeko, 0PM2, MOLP8, and NCI-H929. Representative data for an experiment with the EJM cells are shown in Fig. 7. It was observed that viability of the EJM cells decreased with increasing amount of the exemplary 02B05 BCMA trispecific antigenbinding protein in the presence or absence of human serum albumin (HSA), whereas a control GFP targeting trispecific protein did not affect cell viability. In the presence of albumin, higher concentrations of BCMA trispecific protein were needed to reduce viability of the EJM cells. The EC50 values for cell killing by BCMA trispecific protein for the EJM cells as well as the Jeko, 0PM2, M0L8, and NCI-H929 cells in the absence or presence of HSA are provided in Table 5. With all five cell lines, the exemplary 02B05 BCMA trispecific antigen-binding protein directed T cells to kill target cells in the presence of HSA.

Ability of an exemplary BCMA targeting trispecific protein to mediate T cell killing of cancer cells expressing BCMA, using a smaller target cell to effector cell ratio

[00289] In the standard TDCC assay (as described in Example 1), a ratio 1 target cell (EJM cells or 0PM2 cells) per 10 effector cells (T cells) is used in a 48 hour assay. In this experiment, the ability of exemplary BCMA trispecific protein 02B05 (SEQ ID NO: 520) to direct T cells to kill target cells with smaller target cell to effector ratios was tested. The expectation was that less killing would be observed when fewer effector cells were used. Two BCMA expressing cell lines were tested, EJM and 0PM2, using target to effector cell ratios of 1:1, 1:3, and 1:10, and the experiment was performed in the presence of 15 mg/ml HSA. A GFP targeting trispecific protein was used as a negative control. Data from this experiment is shown in Fig. 8 (TDCC assay with EJM cells) and Fig. 9 (TDCC assay with 0PM2 cells). As expected, near complete killing of the target cells was observed with a 1:10 target to effector cell ratio. The amount of killing was reduced with decreasing effector cells. The EC50 values for cell killing with each ratio are listed in Table 6 (n/d indicates insufficient killing was observed to calculate an EC50 value). The EC50 values increased when fewer effector cells were present. Thus, as expected, reducing the number of effector cells to target cells reduced TDCC activity of the BCMA trispecific protein.

Example

Ability of an exemplary BCMA targeting trispecific protein to mediate T cell killing of cancer cells expressing BCMA, in a time course study, using a smaller target cell to effector cell ratio

[00291] In the standard TDCC assay (Example 1), a ratio 1 target cell per 10 effector cells (T cells) is used in a 48 hour assay. In this experiment, a time course was performed using a 1 to 1 ratio of target cells (EJM cells) to effector cells (T cells). The expectation was that with increased time, a 1 to 1 ratio would result in target cell killing. The experiment was performed in the presence of 15 mg/ml HSA. A GFP targeting trispecific protein was used as a negative control. Target cell viability was measured on days 1, 2, 3, and 4 following incubation of the target cells and effector cells, at a 1:1 ratio, in presence of the exemplary 02B05 BCMA trispecific antigen-binding protein and 15 mg/ml HSA, or the GFP targeting trispecific protein and 15 mg/ml HSA. While no target cell killing was observed on day 1, killing was observed at all other time points in the presence of the BCMA trispecific antigen-binding protein, with the amount of killing increasing with time (Fig. 10). Killing with not observed with the GFP targeting trispecific protein. The EC50 values calculated for cell killing on each day are provided in Table 7 (n/d indicates insufficient killing to determine an EC50 value). From this study it was concluded that the exemplary 02B05 BCMA trispecific protein was able to direct T cell killing with lower numbers of effector cells, but more time was needed to achieve more complete killing.

Example

Ability of an exemplary BCMA targeting trispecific protein to direct human T cells to kill BCMA expressing cells

[00293] Exemplary BCMA trispecific protein 02B05 (SEQ ID NO: 520) was tested for its ability to direct T cells from four different anonymous human donors to kill four different BCMA expressing cells in the presence of 15 mg/ml human serum albumin (HSA) using a standard TDCC assay as described in Example 1. The BCMA expressing cell lines were EJM, NCI-H929, 0PM2, and RPMI8226. As negative controls, two cell lines that lack BCMA expression, OVCAR8 and NCI-H510A, were also tested in the TDCC assays. A control GFP targeting trispecific protein was also used as a negative control. With the four BCMA expressing cell lines and all four T cell donors, cell viability decreased with increasing amounts of the BCMA trispecific protein but not with the GFP trispecific protein (Figs. 11,12,13, and 14). The EC5o values for cell killing are provided in Table 8. The exemplary 02B05 BCMA trispecific antigen-binding protein did not direct killing of the cell lines lacking BCMA expression (Figs. 15 and 16). Thus, it was inferred that the exemplary 02B05 BCMA trispecific antigen-binding protein was able to direct T cells from multiple donors to kill a spectrum of BCMA expressing cell lines.

Ability of an exemplary BCMA targeting trispecific protein to direct cynomolgus T cells to kill BCMA expressing cells

[00295] Exemplary BCMA targeting trispecific protein 02B05 (SEQ ID NO: 520) was tested for its ability to direct T cells from cynomolgus monkeys to kill BCMA expressing cells in the presence of 15 mg/ml human serum albumin (HSA). The experimental conditions were the

WO 2019/075359 same as described in Example 1 except peripheral blood mononuclear cells (PBMC) from cynomolgus monkeys were used as a source of T cells. Two BCMA expressing cell lines were tested, RPMI8226 and NCI-H929. As shown in Figs. 17 and 18, the BCMA trispecific protein was able to direct T cells present in the cynomolgus PBMCs to kill the two BCMA expressing cell lines. The EC50 values for the cell killing are listed in Table 9. A GFP trispecific protein did not affect viability of the BCMA expressing cells. Thus, the BCMA expressing trispecific protein, which can bind cynomolgus CD38 (as shown in Example 5), can direct cynomolgus T cells to kill cells expressing human BCMA.

Exemplary BCMA trispecifc antigen-binding protein and target tumor cell-mediated induction of T cell activation

[00297] Exemplary BCMA targeting trispecific protein 02B05 (SEQ ID NO: 520) was tested for its ability to activate T cells in the presence of BCMA expressing cells. The BCMA expressing cell lines were EJM, OPM2, and RPMI8226. As negative controls, two cells lines that lack BCMA expression were also included, OVCAR8 and NCI-H510A. T cells were obtained from four different anonymous human donors. The assays were set up using the conditions of a standard TDCC assay as described in Example 1 except the assay was adapted to 96 well format and the assay was carried out in the presence of 15 mg/ml HSA. After the 48 hour assay, T cell activation was assessed by using flow cytometry to measure expression of T cell activation biomarkers CD25 and CD69 on the surface of the T cells. With increasing concentrations of the exemplary 02B05 BCMA trispecific antigen-binding protein increased expression of CD69 and CD25 was observed on T cells when co-cultured with the BCMA expressing cells (as shown in Figs. 19-24) Thus, the observed increased expression was dependent on interaction of the BCMA binding sequence within the exemplary 02B05 BCMA trispecific antigen-binding protein with BCMA, as little to no activation was observed with a control GFP trispecific protein (as shown in Figs. 19-24) or with target cells with no BCMA expression (as shown in Figs. 25-28). Therefore the exemplary 02B05 BCMA trispecific antigen-binding protein activated T cells in

co-cultures containing BCMA expressing cells. This conclusion is bolstered by additional data. For instance, expression of a cytokine, TNFa, was measured in the medium collected from a coculture of T cells and BCMA expressing target cells treated with increasing concentrations of the exemplary 02B05 BCMA trispecific antigen-binding protein or with the negative control GFP trispecific protein. The co-cultures were set up using the conditions of a standard TDCC assay (as described in Example 1) supplemented with 15 mg/ml HSA. TNFa was measured using an electrochemiluminescent assay (Meso Scale Discovery). Robust induction of TNFa expression was observed with the 02B05 exemplary BCMA targeting trispecific protein and not the GFP trispecific protein (Fig. 29). This result further supports that the 02B05 exemplary BCMA targeting trispecific protein activated T cells in co-cultures containing BCMA expressing cells.

Example

Pharmacokinetics of an exemplary BCMA targeting trispecific protein of this disclosure

[00298] Cynomolgus monkeys were administered single intravenous doses of an exemplary BCMA targeting trispecific protein (02B05) (SEQ ID NO: 520), at 0.01 mg/kg, 0.1 mg/kg, or 1 mg/kg. Two animals were included per dose group. Following the administration, serum samples were collected and analyzed by two different electrochemiluminescent assays. One assay used biotinylated CD38 as a capture reagent and detected with sulfo tagged BCMA (termed the functional assay). Another assay used as a capture reagent a biotinylated antibody recognizing the anti-albumin domain in the exemplary BCMA targeting trispecific protein and used as a detection reagent a sulfo tagged antibody recognizing the anti-CD3 binding domain in the exemplary BCMA targeting trispecific protein (i.e., an anti-idiotype antibody). The results from the electrochemiluminescent assays are plotted in Fig. 32. As seen in Fig. 32, the exemplary BCMA targeting trispecific protein was detected in the cynomolgus serum samples, even after 504 hours after the administration. The exemplary BCMA targeting trispecific protein was identified using both the sulfo-tagged BCMA (lines labeled using the term “functional” in Fig. 32) and by the anti-idiotype antibody (lines labeled using the term “anti-idiotype” in Fig. 32).

[00299] To confirm that the exemplary BCMA targeting trispecific protein retained the ability to direct T cells to kill BCMA expressing EJM cells, after in vivo administration, serum samples from the 168 hour time point were tested in a TDCC assay (as described in Example 1) in the presence of 16.7% serum from a cynomolgus monkey that has not been exposed to a BCMA targeting trispecific protein, titrating the exemplary BCMA targeting trispecific protein using the protein concentrations determined using the electrochemiluminescent assays (shown in

Fig. 33). Fresh diluted exemplary 02B05 BCMA trispecific protein was compared to the BCMA trispecific protein collected from the test cynomolgus monkeys at 168 h. A GFP trispecific protein was included as a negative control. This study demonstrated that the exemplary BCMA targeting trispecific protein collected from the test cynomolgus monkeys’ serum had identical activity as freshly diluted protein, and that the protein in the serum samples retained the ability to direct T cells to kill BCMA expressing target cells.
