Description

[Technical field]

[0001] This application contains a sequence listing in computer readable format, which is incorporated herein by reference.

[0002] The present invention relates to magnetic carriers, anti-glycoprotein antibodies, antigen-binding portions thereof, one or more lectins, compositions, kits, methods and uses thereof, including their use in methods of glycoprofiling of glycoproteins using lectins, for example in the diagnosis of cancer (e.g. Table 1). The magnetic carriers, anti-glycoprotein antibodies, antigen-binding portions thereof, one or more lectins, compositions, kits, methods and uses based thereon are applicable to any glycoprotein (e.g. Table 1). However, due to their superior sensitivity and / or specificity, the magnetic carriers, anti-glycoprotein antibodies, antigen-binding portions thereof, one or more lectins, compositions, kits, methods and uses based thereon of the present invention are particularly suitable for isoform-specific detection and analysis of glycoproteins (e.g. in the diagnosis of cancer). [Background technology]

[0003] Prostate-specific antigen (PSA) assays have revolutionized prostate cancer (PCa) screening because elevated serum PSA levels precede clinical diagnosis of PCa disease by 5-10 years or even more. However, PSA is also elevated in many benign conditions, leading to a large number of false PSA-positive tests. Furthermore, PSA does not distinguish between significant and insignificant tumors. Thus, in a large subset of patients diagnosed with PCa, the disease progresses slowly and is clinically harmless. These patients are at risk of side effects from unnecessary procedures. Thus, the major problem with PSA-based PCa screening is the unnecessary, expensive, and intrusive testing for patients (e.g., imaging, prostate biopsy, etc.). For these reasons, the United States Preventive Services Task Force (USPSTF) proposed in 2012 to discontinue the use of PSA for PCa screening. The same organization published guidance in 2017 for the use of PSA for individualized PCa screening in men aged 55–69 years.

[0004] Among PCa patients diagnosed after a moderately positive (4-10 ng / ml) PSA screening test, nearly 75% of tumors are organ-confined and potentially curable, whereas in patients with PSA levels above 10 ng / mL, the proportion of organ-confined and curable PCa drops below 50%. Thus, detecting curable PCa with high specificity (avoiding unnecessary follow-up examination procedures) is a diagnostic challenge. Moreover, overdiagnosis / overtreatment may cause complications including urinary incontinence, sexual dysfunction, and bowel problems in patients with harmless PCa. Therefore, improved screening tests would also allow for classification of tumors according to their clinical significance. Summary of the Invention [Problem to be solved by the invention]

[0005] PCa screening is usually recommended for men over 55 years of age by measuring PSA in serum. Existing methods used in clinical laboratories worldwide are not sensitive or specific enough, so it is often very difficult to accurately identify healthy from PCa patients at an early, potentially curable stage. Thus, clinicians / urologists are in need of novel diagnostically useful PCa biomarkers. [Means for solving the problem]

[0012] The present invention further relates to a method for diagnosing that a subject may be at risk for or suffer from an inflammatory disease, the method comprising: (a) contacting a sample obtained from the subject that contains an inflammatory disease biomarker protein with an antibody to the inflammatory disease biomarker protein to form an antibody-inflammatory disease biomarker protein complex; (b) isolating the antibody-protein complex obtained in step (a); and (c) contacting the antibody-inflammatory disease biomarker protein complex with one or more lectins to determine the glycoprofile of the inflammatory disease biomarker protein; Deviation of the glycoprofile from a healthy glycoprofile of the inflammatory disease biomarker protein indicates that the subject may be at risk for or suffer from an inflammatory disease.

[0013] In the method of diagnosing that a subject may be at risk for or suffer from an inflammatory disease, it is preferred that the antibody in step (a) is not immobilised, preferably not immobilised on a solid surface, and / or that the protein is not released from the antibody when the method is being performed.

An S-linked glycan is a carbohydrate attached to the -SH group of cysteine. A C-linked glycan is a carbohydrate attached to tryptophan by a C-C bond.

[0026] The term "carbohydrate" refers to a substance with the stoichiometric chemical formula C n (H2O) n (e.g., aldoses, ketoses, etc.). The general term "carbohydrate" includes monosaccharides, oligosaccharides, and polysaccharides, as well as substances derived from monosaccharides by reduction of a carbonyl group (alditols), by oxidation of one or more terminal groups to a carboxylic acid, or by replacement of one or more hydroxyl groups by a hydrogen atom, an amino group, a thiol group, or a similar group. The general term "carbohydrate" also includes derivatives of these compounds.

[0027] The term "glycoprofile of a protein" refers to the carbohydrate structure of a protein, e.g., the composition and / or structure of covalently bound carbohydrates, e.g., the amount, presence, or absence of covalently bound carbohydrates.

[0028] The term "glycoprofiling" refers to determining the carbohydrate structure (e.g., the composition and / or structure of covalently bound carbohydrates, e.g., the amount, presence, or absence of covalently bound carbohydrates) of a glycoconjugate, such as a glycoprotein, a glycolipid, or a proteoglycan.

[0029] The term "DART" refers to dual-affinity re-targeting antibodies, which are bispecific antibody-derived molecules capable of simultaneously binding to two distinct cell surface molecules (e.g., Sung JAM et al., 2015).

[0030] The term "Adnectin" (or "monobody") refers to synthetic binding proteins capable of binding antigens; for example, they can be constructed using the fibronectin type III I domain (FN3) as a molecular scaffold. Monobodies are a simple and robust alternative to antibodies in generating target-binding proteins.

[0031] The term "single domain antibody" (or "nanobody") refers to an antibody fragment consisting of a single monomeric variable antibody domain.

[0032] The term "FN3 scaffold" refers to a fibronectin type III domain I (FN3) scaffold that can be used as a non-antibody scaffold in generating binding proteins (e.g., antigen-binding proteins) (e.g., Koide A. et al., 2012).

[0033] The term "affibody" refers to a group of engineered affinity proteins that are capable of binding to target proteins or peptides with high affinity that mimics monoclonal antibodies and are therefore a member of a family of antibody-mimetic molecules (e.g., Lofblom J et al., 2010).

[0034] The term "anticalin" refers to an artificial protein capable of binding to an antigen and either to a protein or to a small molecule. Anticalins are not structurally related to antibodies and are a class of antibody mimetic molecules. Preferably, an "anticalin" is a protein derived from lipocalin (also known as cytosolic fatty acid binding protein) that has been genetically modified to alter its binding properties. Anticalins have the advantages of the specificity of monoclonal antibodies for small lipid molecules (e.g., steroids, bilins, retinoids, and lipids), excellent tissue penetration, and thermal stability, but without the large size (e.g., they are 1 / 8 times smaller) and can be batch produced in E. coli, without the need for extraction from animals.

[0035] "Avimer" (e.g., an abbreviation of avidity multimer) refers to an artificial protein capable of specifically binding to an antigen through multiple binding sites. Avimers are structurally unrelated to antibodies and are classified as a class of antibody mimetic molecules.

[0036] The term "cyclic peptide" refers to a polypeptide chain that contains a circular arrangement of bonds. The term "bicyclic peptide" (e.g., amanitin in amatoxins, phalloidin in phallotoxins) generally refers to a cyclic peptide that contains a bridging group (e.g., a thioether or disulfide bond) between two polypeptide side chains. In amatoxins, this bridge is formed as a thioether between Trp and Cys residues. Other bicyclic peptides include echinomycin, triostin A, and serogentin C. There are also cyclic peptide hormones that are cyclized by a disulfide bond between two cysteines, such as somatostatin and oxytocin. For example, a "bicyclic peptide" screening and production method can use a phage library displaying peptides that contain three Cys residues. The phage is treated under mild conditions with tris-(bromomethyl)benzene, which reacts with all three cysteines, forming two peptide loops of six amino acids that are linked to the benzene ring (e.g., Mund T et al., 2014).

[0037] "DARPins" (short for "designed ankyrin repeat proteins") refer to engineered antibody mimetic molecular proteins that exhibit high specificity and high affinity target protein binding. They are derived from natural ankyrin proteins that are responsible for diverse functions such as cell signaling, cell regulation and structural integrity. DARPins consist of at least three repeat motif proteins, usually four or five repeat motif proteins. Their molecular mass is approximately 14 or 18 kDa (kilodaltons) for four or five repeat DARPins, respectively (e.g. Pluckthun A, 2015; Rasool M et al., 2017).

[0038] The term "Kunitz domain" refers to an active domain of a protein capable of inhibiting the function of a proteolytic enzyme (e.g., a protein domain characteristic of inhibitors of the S1 serine peptidase family). Preferred examples include aprotinin, trypstatin, rat mast cell trypsin inhibitor, and tissue factor pathway inhibitor (TFPI).

[0039] The term "obody" refers to a single domain protein module (e.g., a single domain scaffold) that can bind to a specific target molecule (e.g., protein, carbohydrate, nucleic acid, and small molecule ligand) (e.g., Steemson JD et al., 2014).

[0040] The term "aptamer" refers to an oligonucleotide or peptide molecule that binds to a specific target molecule.

[0041] The term "agglutinin" refers to any substance that causes cells to clump together (i.e., clump together), particularly certain antibodies that form in the blood in response to the presence of an invading agent, or lectins that have such an effect. More specifically, the term "agglutinin," as used herein, refers to carbohydrate-binding proteins (lectins, see 153).

[0042] The term "glycan" refers to a compound consisting of glycosidically linked monosaccharides, and can also refer to the carbohydrate portion of a glycoconjugate such as a glycoprotein, glycolipid, or proteoglycan, even if the carbohydrate is only a monosaccharide or oligosaccharide.

[0043] As used herein, the term "lectin" refers to a carbohydrate-binding protein. Lectins may have high specificity for carbohydrate moiety(s) (e.g., lectins react specifically with terminal glycosidic residues of other molecules, such as glycans of glycoproteins (e.g., branched sugar molecules of glycoproteins, such as target polypeptides in the sense of the present invention and biomarkers as described in Table 1 herein). Lectins are well known in the art. A person skilled in the art can easily determine which lectins can be used to bind carbohydrate moiety(s) of interest, such as carbohydrate moiety(s) of glycans attached to proteins. Preferred lectins to be applied in the context of the present invention are described herein. The term "lectin" also includes siglecs (sialic acid-binding immunoglobulin-like lectins). In particular, as used herein, the term "lectin" also refers to carbohydrate-binding antibodies. Thus, as used herein, the term "lectin" includes lectins, siglecs, and carbohydrate-binding antibodies.

[0044] As used herein, an "antibody" is a protein comprising one or more polypeptides (including one or more binding domains, preferably antigen binding domains) substantially or partially encoded by immunoglobulin genes or fragments of immunoglobulin genes. Preferably, an antibody to a protein whose glycoprofile has been determined as described herein is not directed to a glycochain attached to the protein. Stated differently, an antibody to a protein whose glycoprofile has been determined as described herein is preferably directed to the protein itself, i.e., to an epitope within the amino acid sequence of the protein. The epitope may be a linear epitope or a conformational epitope. The epitope may be a continuous epitope or a discontinuous epitope. The term "immunoglobulin" (Ig) is used interchangeably with "antibody" herein. Recognized immunoglobulin genes include the kappa, lambda, alpha, gamma, delta, epsilon, and mu constant region genes, as well as the myriad immunoglobulin variable region genes. In particular, as used herein, an "antibody" is typically a tetrameric glycosylated protein composed of two light (L) chains of about 25 kDa each and two heavy (H) chains of about 50 kDa each. Two types of light chains, called lambda and kappa, may be found in antibodies. Depending on the amino acid sequence of the constant domain of the heavy chain, immunoglobulins can be classified into five main classes, A, D, E, G, and M, some of which can be further divided into subclasses (isotypes), e.g., IgG1, IgG2, IgG3, IgG4, IgA1, and IgA2, with IgG being preferred in the context of the present invention. Antibodies of the present invention are also envisaged that have an IgE constant domain or a portion thereof that is bound to the Fc epsilon receptor I. IgM antibodies consist of five basic heterotetrameric units with an additional polypeptide called the J chain and contain ten antigen-binding sites, whereas IgA antibodies contain two to five basic four-chain units that polymerize and combine with the J chain to form multivalent aggregates. For IgG, the four-chain unit is typically about 150,000 daltons.Each light chain comprises an N-terminal variable (V) domain (VL) and a constant (C) domain (CL). Each heavy chain comprises an N-terminal V domain (VH), three or four C domains (CH), and a hinge region. The constant domains are not directly involved in binding the antibody to the antigen, but may exhibit various effector functions, such as involvement in antibody-dependent cellular cytotoxicity (ADCC). If the antibody confers ADCC, it is preferably of the IgG1 subtype, while the IgG4 subtype is not considered to have the ability to confers ADCC.

[0045] The term "antibody" also includes, but is not limited to, monoclonal antibodies, monospecific antibodies, multispecific or multi-specific antibodies such as bispecific antibodies, humanized antibodies, camelized antibodies, human antibodies, single-chain antibodies, chimeric antibodies, synthetic antibodies, recombinant antibodies, hybrid antibodies, mutated antibodies, grafted antibodies, and in vitro generated antibodies, with chimeric or humanized antibodies being preferred. The term "humanized antibody" is generally defined for antibodies in which the specificity-encoding CDRs of the HC and LC have been transferred onto a suitable human variable framework ("CDR grafted"). The term "antibody" also includes scFv, single-chain antibodies, diabodies or tetrabodies, domain antibodies (dAbs), and nanobodies. In the present invention, the term "antibody" is also intended to include dimeric, trimeric, or multimeric antibodies having multiple antigen-binding sites, or bifunctional, trifunctional, or multifunctional antibodies. The term also includes antigen-binding portions. The term "antibody" also includes an FN3 scaffold, an adnectin, an affibody, an anticalin, an avimer, a bicyclic peptide, a DARPin, a Kunitz domain, an obody, or an aptamer, such as a DNA, RNA or peptide aptamer.

[0046] Preferred antibodies of the present invention include, but are not limited to, anti-PSA antibody, anti-AFP antibody, anti-MUC16 antibody, anti-WFDC2 antibody, anti-MUC1 antibody, anti-ERBB2 antibody, anti-CEACAM5 antibody, anti-FUT3 antibody, or anti-TG antibody, etc. Further preferred antibodies related to the present invention are shown in Table 1 below.

[0047] Furthermore, the term "antibody" as used in the present invention also relates to derivatives (including fragments) of the antibodies described herein. A "derivative" of an antibody includes an amino acid sequence that has been altered by the introduction of substitutions, deletions, or additions of amino acid residues. Furthermore, derivatives include antibodies that have been modified by the covalent attachment of any type of molecule to the antibody or protein. Examples of such molecules include, but are not limited to, sugars, PEG, hydroxyl groups, ethoxy groups, carboxy groups, or amine groups. In effect, covalent modifications of antibodies result in, but are not limited to, glycosylation, pegylation, acetylation, phosphorylation, amidation.

[0048] The antibody of the present invention is preferably an "isolated" antibody. When used to describe the antibodies disclosed herein, "isolated" means an antibody that has been identified, separated, and / or recovered from components of its production environment. Preferably, an isolated antibody is free of association with all other components from its production environment. Contaminating components of its production environment, such as those resulting from recombinantly transfected cells, are typically substances that may interfere with diagnostic or therapeutic uses of the polypeptide and may include enzymes, hormones, and other proteinaceous or non-proteinaceous solutes. In a preferred embodiment, the antibody can be (1) purified sufficiently to obtain at least 15 residues of N-terminal or internal amino acid sequence using a spinning cup sequenator, or (2) purified to homogeneity by SDS-PAGE under non-reducing or reducing conditions using Coomassie blue, or preferably silver staining. Ordinarily, however, an isolated antibody can be prepared by at least one purification step.

[0049] As used herein, the term "antigen-binding portion" refers to a fragment of an immunoglobulin (or an intact antibody) and includes any polypeptide that contains an antigen-binding fragment or an antigen-binding domain. Preferably, it includes fragments such as Fab, F(ab'), F(ab')2, Fv, scFv, Fd, disulfide-linked Fv (sdFv), and other antibody fragments that retain antigen-binding function as described herein (e.g., single-chain antibody fragments (scAbs)). Typically, such fragments contain the antigen-binding domain and may have the same properties as the antibodies described herein.

[0050] Preferred antigen-binding portions of antibodies of the invention include, but are not limited to, antigen-binding portions of anti-PSA, anti-AFP, anti-MUC16, anti-WFDC2, anti-MUC1, anti-ERBB2, anti-CEACAM5, anti-FUT3, or anti-TG antibodies. Further preferred antibodies in the context of the invention are shown in Table 1 below.

[0051] As used herein, the term "specifically binds" refers to an antibody or a fragment or derivative thereof that specifically binds to a target glycoprotein or target polypeptide and does not specifically bind to other proteins or polypeptides. The antibodies or fragments or derivatives thereof according to the invention bind to their respective targets via the variable domains of the antibody.

[0052] Preferred anti-glycoprotein antibodies or antigen-binding portions thereof include: i) prostate specific antigen (PSA), preferably SEQ ID NO: 1, 2, 3, 4, 5, or 6; more preferably SEQ ID NO: 6; ii) alpha-fetoprotein (AFP), preferably SEQ ID NO: 11 or 12; more preferably SEQ ID NO: 12; iii) mucin-16 (MUC16), preferably SEQ ID NO: 13; vi) WAP4-disulfide core domain protein 2 (WFDC2), preferably SEQ ID NO: 14, 15, 16, 17, 18, or 19; more preferably SEQ ID NO: 19; v) mucin-1 (MUC1), preferably SEQ ID NO: 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, or 37; more preferably SEQ ID NO: 28, No. 37; vii) receptor tyrosine protein kinase erbB-2 (ERBB2), preferably SEQ ID NO: 38, 39, 40, 41, 42, 43, or 44; more preferably SEQ ID NO: 44; viii) carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5), preferably SEQ ID NO: 45, 46, or 47; more preferably SEQ ID NO: 47; ix) galactoside 3(4)-L-fucosyltransferase (FUT3), preferably SEQ ID NO: 48; x) thyroglobulin (TG), preferably SEQ ID NO: 49, 50, or 51; more preferably SEQ ID NO: 51. Further preferred antibodies in the context of the present invention are shown in Table 1 below.

[0053] The term "epitope" also refers to a site on an antigen (in the context of the present invention, the antigen is a glycoprotein) to which an antibody molecule binds. Preferably, the epitope is a site on an antibody or an antigen-binding portion thereof, preferably a molecule to which the antibody is raised and / or to which the antibody binds (in the context of the present invention, the antigen is a glycoprotein). For example, an epitope can be recognized by an antibody or an antigen-binding portion thereof. An epitope may be a linear epitope or a conformational epitope. An epitope may be a continuous epitope or a discontinuous epitope. A "linear epitope" is an epitope whose primary amino acid sequence comprises the recognized epitope. A linear epitope typically comprises at least 3, more usually at least 5, e.g., about 8 to about 10 amino acids in a unique sequence.

[0054] Specific binding is believed to be influenced by specific motifs in the amino acid sequences of the binding domain and the antigen that bind to each other as a result of their primary, secondary or tertiary structure and as a result of secondary modifications of said structure. The specific interaction of the antigen interaction site with its specific antigen can also result in the simple binding of the site to the antigen. Furthermore, the specific interaction of the antigen interaction site with its specific antigen can alternatively result in the initiation of a signal, for example by inducing a change in the structure of the antigen, oligomerization of the antigen, etc. A preferred example of a binding domain according to the present invention is an antibody.

[0055] Typically, the binding affinity is 10 -6 Binding is considered specific when the binding affinity is greater than M. Preferably, the binding affinity is about 10 -11 ~about 10 -8 M(K D ), preferably about 10 -11 ~about 10 -9 Binding is considered to be specific when M. If necessary, non-specific binding can be reduced by altering the binding conditions without substantially affecting specific binding.

[0056] When the sugar chain is bound to a lectin, the binding affinity is preferably 10 -3 ~10 -6 (K D ) range. The corresponding K for binding glycans to lectins D Methods for measuring are known in the art and readily available to one of skill in the art.

[0057] Whether an antibody or antigen-binding portion thereof reacts specifically as described above can be readily tested, inter alia, by comparing the reaction of the antibody or antigen-binding portion thereof with its respective target glycoprotein with the reaction of the antibody or antigen-binding portion thereof with other non-target proteins.

[0058] The term "polypeptide" is used herein in the same way as the term "protein". Proteins (including fragments thereof, preferably biologically active fragments, and peptides, usually having less than 30 amino acids) comprise one or more amino acids (resulting in an amino acid chain) bound together via covalent peptide bonds. The term "polypeptide" as used herein refers to a group of molecules, e.g., consisting of more than 30 amino acids. Polypeptides can further form multimers, such as dimers, trimers, and higher oligomers, i.e., consisting of two or more polypeptide molecules. The polypeptide molecules forming such dimers, trimers, etc., can be identical or non-identical. The corresponding higher order structures of such multimers are consequently referred to as homo- or heterodimers, homo- or heterotrimers, etc. An example of a heteromultimer is an antibody molecule, which in its naturally occurring form consists of two identical polypeptide light chains and two identical polypeptide heavy chains. The terms "polypeptide" and "protein" also refer to naturally modified polypeptides / proteins, where the modifications are affected by post-translational modifications, e.g., glycosylation, acetylation, phosphorylation, etc. Such modifications are known in the art.

[0059] The term "amino acid" or "amino acid residue" typically refers to an amino acid having its art-recognized definition, such as an amino acid selected from the group consisting of alanine (Ala or A); arginine (Arg or R); asparagine (Asn or N); aspartic acid (Asp or D); cysteine ​​(Cys or C); glutamine (GIn or Q); glutamic acid (GIu or E); glycine (GIy or G); histidine (His or H); isoleucine (He or I); leucine (Leu or L); lysine (Lys or K); methionine (Met or M); phenylalanine (Phe or F); proline (Pro or P); serine (Ser or S); threonine (Thr or T); tryptophan (Trp or W); tyrosine (Tyr or Y); and valine (VaI or V), although modified, synthetic, or rare amino acids can be used if desired. In general, amino acids can be grouped as having nonpolar side chains (e.g., Ala, Cys, He, Leu, Met, Phe, Pro, VaI); negatively charged side chains (e.g., Asp, GIu); positively charged side chains (e.g., Arg, His, Lys); or polar uncharged side chains (e.g., Asn, Cys, GIn, GIy, His, Met, Phe, Ser, Thr, Trp, and Tyr).

[0060] "Polyclonal antibody" or "polyclonal antiserum" refers to an immune serum containing a mixture of antibodies specific for one (monovalent or specific antiserum) or more (polyvalent antiserum) antigens, which can be prepared from the blood of an animal immunized with an antigen(s).

[0061] Furthermore, the term "antibody" as used in the present invention also relates to derivatives or variants of the antibodies described herein that exhibit the same specificity as the antibodies described herein. Examples of "antibody variants" include humanized variants of non-human antibodies, "affinity matured" antibodies (see, e.g., Hawkins et al. J. Mol. Biol. 254, 889-896 (1992) and Lowman et al., Biochemistry 30, 10832- 10837 (1991)), and antibody mutants with altered effector functions (see, e.g., U.S. Patent No. 5,648,260).

[0062] As used herein, the terms "antigen-binding domain", "antigen-binding portion", "antigen-binding fragment" and "antibody-binding region" refer to a portion of an antibody molecule that contains amino acids responsible for the specific binding between the antibody and the antigen. The portion of the antigen that is specifically recognized and bound by the antibody is referred to as an "epitope" as described above in this specification. As described above, an antigen-binding domain typically includes an antibody light chain variable region (VL) and an antibody heavy chain variable region (VH), but may not include both. An Fd fragment, for example, has two VH regions and often retains some antigen-binding function of a normal antigen-binding domain. Examples of antigen-binding fragments of antibodies include (1) a Fab fragment, which is a monovalent fragment having the VL, VH, CL, and CH1 domains; (2) a F(ab')2 fragment, which is a bivalent fragment having two Fab fragments linked by a disulfide bridge at the hinge region; (3) an Fd fragment having two VH and CH1 domains; (4) an Fv fragment having two VH and VH domains in a single antigen arm; (5) a dAb fragment having a VH domain (Ward et al., (1989) Nature 341:544-546); (6) an isolated complementarity-determining region (CDR); and (7) a single-chain Fv (scFv). Although the two domains of the Fv fragment, VL and VH, are encoded by separate genes, they can be joined using recombinant techniques by a synthetic linker that allows the VL and VH regions to pair into a single protein chain forming a monovalent molecule (known as a single-chain Fv (scFv); see, e.g., Bird et al. (1988) Science 242:423-426; and Huston et al. (1988) Proc. Natl. Acad. Sci USA 85:5879-5883). These antibody fragments are obtained using conventional techniques known to those of skill in the art, and the fragments are evaluated for function in the same manner as intact antibodies.

[0063] The term "monoclonal antibody" as used herein refers to an antibody obtained from a population of substantially homogeneous antibodies, i.e., the individual antibodies constituting the population are identical except for possible minor amounts of naturally occurring mutations and / or post-translational modifications (e.g., isomerization, amidation). Monoclonal antibodies are highly specific, being directed against a single antigenic site. Moreover, in contrast to conventional (polyclonal) antibody preparations that typically contain different antibodies directed against different determinants (epitopes), each monoclonal antibody is directed against a single determinant on the antigen. In addition to their specificity, monoclonal antibodies are advantageous in that they are synthesized by a hybridoma culture uncontaminated by other immunoglobulins. The modifier "monoclonal" indicates the character of the antibody as being obtained from a population of substantially homogeneous antibodies and is not to be construed as requiring production of the antibody by any method. For example, the monoclonal antibodies to be used in the present invention may be made by the hybridoma method first described by Kohler et al. (Nature, 256: 495 (1975)), or may be made by recombinant DNA methods (see, e.g., U.S. Pat. No. 4,816,567). The "monoclonal antibodies" may also be isolated from phage antibody libraries using the techniques described, for example, in Clackson et al. (Nature, 352: 624-628 (1991)) and Marks et al. (J. Mol. Biol., 222: 581-597 (1991)).

[0064] Furthermore, the term "monoclonal antibody" as used in the present invention also relates to specific monoclonal antibodies such as those produced by DB Biotech (http: / / www.dbbiotech.com / about-us.html), which method involves an in vitro cloning technique that allows the production of pure immunoglobulin fractions corresponding to a single clone of B lymphocytes, with the resulting immunoglobulin recognizing only a single linear epitope on the antigen molecule.

[0065] Monoclonal antibodies herein include, inter alia, "chimeric" antibodies (immunoglobulins) in which portions of the heavy and / or light chains are identical or homologous to corresponding sequences of antibodies from a particular species or belonging to a particular antibody class or subclass, while the remainder of the chains are identical or homologous to corresponding sequences of antibodies from another species or belonging to another antibody class or subclass, and fragments of such antibodies, so long as the desired biological activity is exhibited (U.S. Pat. No. 4,816,567; Morrison et al., Proc. Natl. Acad. Sci. USA, 81: 6851-6855 (1984)). Chimeric antibodies of interest herein include "primitized" antibodies that contain variable domain antigen-binding sequences derived from a non-human primate (e.g., Old World Monkey, Ape, etc.) and human constant region sequences.

[0066] "Humanized" forms of non-human (e.g., murine) antibodies are chimeric immunoglobulins, immunoglobulin chains or fragments thereof (such as Fv, Fab, Fab', F(ab')2, or other antigen-binding sequences of antibodies) of mostly human sequence that contain minimal sequence derived from non-human immunoglobulin. For the most part, humanized antibodies are human immunoglobulins (recipient antibody) in which residues from a hypervariable region (also called CDR) of the recipient are replaced by residues from a hypervariable region of a non-human species (donor antibody) such as mouse, rat, or rabbit having the desired specificity, affinity, and capacity. In some instances, Fv framework region (FR) residues of the human immunoglobulin are replaced by corresponding non-human residues. Furthermore, as used herein, "humanized antibodies" can also include residues that are not found in the recipient antibody or in the donor antibody. These modifications are made to further refine and optimize antibody function. Humanized antibodies may also suitably comprise at least a portion of an immunoglobulin constant region (Fc), typically that of a human immunoglobulin. For further details, see Jones et al. (Nature, 321: 522-525 (1986)); Reichmann et al. (Nature, 332: 323-329 (1988)); and Presta (Curr. Op. Struct. Biol., 2: 593-596 (1992)).

[0067] The term "human antibody" includes antibodies having variable and constant regions substantially corresponding to human germline immunoglobulin sequences known in the art, including, for example, those described by Kabat et al. (See, Kabat, et al. (1991) loc. cit.). The human antibodies of the invention may include, for example, in the CDRs, particularly CDR3, amino acid residues not encoded by human germline immunoglobulin sequences (e.g., mutations introduced by random or site-specific mutagenesis in vitro or by somatic mutation in vivo). Human antibodies can have at least one, two, three, four, five, or more positions substituted with an amino acid residue not encoded by human germline immunoglobulin sequences.

[0068] As used herein, "in vitro generated antibody" refers to an antibody in which all or a portion of the variable region (e.g., at least one CDR) is generated by non-immune cell selection (e.g., in vitro phage display, protein chip, or any other method that allows testing the ability of candidate sequences to bind to an antigen). Thus, the term preferably excludes sequences generated by genomic rearrangement in immune cells.

[0069] A "bispecific" or "bifunctional antibody" is an artificial hybrid antibody having two different heavy / light chain pairs and two different binding sites. Bispecific antibodies can be produced in a variety of ways, including fusion of hybridomas or linking of Fab' fragments. See, e.g., Songsivilai & Lachmann, Clin. Exp. Immunol. 79:315-321 (1990); Kostelny et al., J. Immunol. 148, 1547-1553 (1992). In one embodiment, a bispecific antibody comprises a first binding domain polypeptide, such as a Fab' fragment, linked via an immunoglobulin constant region to a second binding domain polypeptide.

[0070] The antibodies described herein can be used to form bispecific molecules. The anti-PSA antibodies or antigen-binding portions thereof can be derivatized or conjugated to another functional molecule, such as another peptide or protein (e.g., another antibody or a ligand for a receptor), to create a bispecific molecule that binds to at least two different binding sites or target molecules. The antibodies described herein may in fact be derivatized or linked to more than one other functional molecule to create a multispecific molecule that binds to more than two different binding sites and / or target molecules. Such multispecific molecules are also intended to be encompassed by the term "bispecific molecule" as used herein. To create the bispecific molecules described herein, the antibodies described herein can be functionally conjugated (e.g., by chemical bond, genetic fusion, non-covalent association, or other means) to one or more other binding molecules, such as another antibody, antibody fragment, peptide, or binding mimetic molecule, such that a bispecific molecule results.

[0071] Immunoconjugates and antibody derivatives. The antibodies described herein can be used for diagnostic purposes, including sample testing and in vivo imaging, and for this purpose, the antibodies (or binding fragments thereof) can be conjugated to a suitable detectable agent to form an immunoconjugate. For diagnostic purposes, suitable agents are detectable labels, including radioisotopes for whole body imaging, radioisotopes, enzymes, fluorescent labels, and other suitable antibody tags for sample testing. The detectable label can be any of a variety of types currently used in the field of in vitro diagnostics, including particulate labels, including metal sols such as colloidal gold, isotopic labels, chromogenic labels, including fluorescent markers, biotin, luminescent markers, phosphorescent markers, and the like, enzyme labels that convert a given substrate into a detectable marker, and polynucleotide tags that are revealed following amplification, such as by polymerase chain reaction, and the like. Biotin-labeled antibodies may also be detectable by binding of avidin or streptavidin. Suitable enzyme labels include horseradish peroxidase, alkaline phosphatase, and the like. For example, the label can be the enzyme alkaline phosphatase, which is detected by measuring the presence or formation of chemiluminescence following conversion of 1,2 dioxetane substrates such as adamantyl methoxyphosphoryloxyphenyl dioxetane (AMPPD), disodium 3-(4-(methoxyspiro{1,2-dioxetane-3,2'-(5'-chloro)tricyclo{3.3.1.1 3,7}decan}-4-yl)phenyl phosphate (CSPD), and CDP and CDP-star, or other luminescent substrates known to those skilled in the art, such as chelates of suitable lanthanides, e.g., terbium(III) and europium(III). The means of detection will be determined by the label chosen. The appearance of the label or its reaction products can be obtained by eye, if the label is particulate and has accumulated at an appropriate level, or using instruments such as spectrophotometers, luminometers, fluorometers, and the like, according to standard measurement techniques.

[0072] Numerous methods known to those skilled in the art are available for obtaining antibodies or antigen-binding fragments thereof. For example, antibodies can be produced using recombinant DNA methods (U.S. Patent No. 4,816,567). Monoclonal antibodies may also be produced by generating hybridomas (see, e.g., Kohler and Milstein (1975) Nature, 256: 495-499) according to known methods. The hybridomas so formed are then screened using standard methods, such as enzyme-linked immunosorbent assay (ELISA) and surface plasmon resonance (BIACORE®) analysis, to identify one or more hybridomas that produce an antibody that specifically binds to the particular antigen. Any form of a particular antigen can be used as the immunogen, for example, recombinant antigens, naturally occurring forms, variants or fragments thereof, and antigenic peptides thereof.

[0073] One exemplary method of generating antibodies involves screening a protein expression library, such as a phage or ribosome display library. Phage display is described, for example, in U.S. Pat. No. 5,223,409 to Ladner et al., Smith ((1985) Science 228:1315-1317), Clackson et al. ((1991) Nature, 352: 624-628), Marks et al. ((1991) J. MoI. Biol., 222: 581-597), WO 92 / 18619, WO 91 / 17271, WO 92 / 20791, WO 92 / 15679, WO 93 / 01288, WO 92 / 01047, WO 92 / 09690, and WO 90 / 02809.

[0074] In addition to using display libraries, a specific antigen can be used to immunize a non-human animal, such as a rodent, such as a mouse, hamster, or rat. In one embodiment, the non-human animal contains at least a portion of a human immunoglobulin gene. For example, it is possible to engineer mouse strains deficient in mouse antibody production with large fragments of the human Ig locus. Using hybridoma technology, antigen-specific monoclonal antibodies derived from genes with the desired specificity can be produced and selected. See, for example, XENOMOUSE®, Green et al. (1994) Nature Genetics 7:13-21, U.S. Patent Application Publication No. 2003-0070185, WO 96 / 34096, and WO 96 / 33735.

[0075] In other embodiments, monoclonal antibodies may be obtained from non-human animals and then modified, e.g., humanized, deimmunized, chimerized, and produced using recombinant DNA techniques known in the art. Various techniques for producing chimeric antibodies have been described. See, for example, Morrison et al. (Proc. Natl. Acad. Sci. USA 81:6851, 1985), Takeda et al. (Nature 314:452, 1985), U.S. Patent No. 4,816,567 to Cabilly et al., U.S. Patent No. 4,816,397 to Boss et al., EP 171496, EP 173494, and GB 2177096 to Tanaguchi et al. Humanized antibodies may also be produced using, for example, transgenic mice that express human heavy and light chain genes but are incapable of expressing endogenous mouse immunoglobulin heavy and light chain genes. Winter describes an exemplary CDR grafting method that can be used to prepare the humanized antibodies described herein (U.S. Patent No. 5,225,539). All of the CDRs of a particular human antibody may be replaced with at least a portion of a non-human CDR, or only a portion of the CDRs may be replaced with a non-human CDR. It is only necessary to replace the number of CDRs necessary to allow the humanized antibody to bind to a given antigen.

[0076] Humanized antibodies or fragments thereof can be made by replacing sequences of Fv variable domains not directly involved in antigen binding with equivalent sequences from human Fv variable domains. Exemplary methods for making humanized antibodies or fragments thereof are provided by Morrison ((1985) Science 229:1202-1207), Oi et al. ((1986) BioTechniques 4:214), and U.S. Pat. Nos. 5,585,089, 5,693,761, 5,693,762, 5,859,205, and 6,407,213. These methods include isolating, manipulating, and expressing nucleic acid sequences that encode all or part of immunoglobulin Fv variable domains from at least one of the heavy or light chains. Such nucleic acids may be obtained from hybridomas producing antibodies against a predetermined target, as described above, or from other sources. The recombinant DNA encoding the humanized antibody molecule can also be cloned into an appropriate expression vector.

[0077] In certain embodiments, humanized antibodies are optimized by introducing conservative substitutions, consensus sequence substitutions, germline substitutions, and / or back mutations. Such modified immunoglobulin molecules can be made by any of several techniques known in the art (e.g., Teng et al., Proc. Natl. Acad. Sci. USA, 80: 7308-7312, 1983; Kozbor et al., Immunology Today, 4: 7279, 1983; Olsson et al., Meth. Enzymol., 92: 3-16, 1982), and can be made following the teachings of WO 92 / 06193 or EP 239400.

[0078] Antibodies or fragments thereof may also be modified by specific deletion or "deimmunization" of human T-cell epitopes by the methods disclosed in WO 98 / 52976 and WO 00 / 34317. Briefly, the heavy and light chain variable domains of the antibody can be analyzed for peptides that bind to MHC class II. These peptides represent potential T-cell epitopes (as defined in WO 98 / 52976 and WO 00 / 34317). For detection of potential T-cell epitopes, a computer modeling approach called "peptide threading" can be applied; furthermore, as described in WO 98 / 52976 and WO 00 / 34317, databases of human MHC class II binding peptides can be searched for motifs present in the VH and VL sequences. These motifs bind to any of the 18 major MHC class IIDR allotypes and therefore constitute potential T-cell epitopes. Detected potential T cell epitopes can be eliminated by substitution of a small number of amino acid residues in the variable domain, preferably by single amino acid substitution. Typically, conservative substitutions are made. In many cases, but not exclusively, common amino acids at positions in human germline antibody sequences can be used. Human germline sequences are published, for example, in Tomlinson et al. ((1992) J. MoI. Biol. 227:776-798), Cook, GP et al. ((1995) Immunol. Today Vol. 16 (5): 237-242), Chothia et al. ((1992) J. MoI. Biol. 227:799-817), and Tomlinson et al. ((1995) EMBO J. 14:4628-4638). The V BASE directory provides a comprehensive directory of human immunoglobulin variable region sequences (Tomlinson, L. A. et al., MRC Centre for Protein Engineering, Cambridge, UK). These sequences can be used as a source of human sequences, e.g., for the framework regions and CDRs.Consensus human framework regions can also be used, for example, as described in US Pat. No. 6,300,064.

[0079] Techniques for generating antibodies, including polyclonal, monoclonal, humanized, bispecific, and heteroconjugate antibodies, are known in the art, some of which are exemplified below.

[0080] Heteroconjugate antibodies Heteroconjugate antibodies are also within the scope of the present invention.

[0081] Heteroconjugate antibodies are composed of two covalently linked (e.g., conjugated) antibodies. For example, one of the antibodies in the heteroconjugate can be conjugated to avidin, the other to biotin. It is contemplated that the antibodies can be prepared in vitro using known methods in synthetic protein chemistry, including those involving cross-linking agents. For example, immunotoxins can be constructed using a disulfide exchange reaction or by forming a thioether bond. Examples of suitable reagents for this purpose include iminothiolate and methyl-4-mercaptobutyrimidate, as well as those disclosed, for example, in U.S. Pat. No. 4,676,980. Heteroconjugate antibodies can be made using any convenient cross-linking method. Suitable cross-linking agents are known in the art and are disclosed in U.S. Pat. No. 4,676,980, along with a number of cross-linking techniques.

[0082] For further antibody production techniques, see Antibodies: A Laboratory Manual, eds. Harlow et al., Cold Spring Harbor Laboratory, 1988. The present invention is not necessarily limited to any particular source, method of production, or other particular characteristics of the antibodies.

[0083] The antibody of the present invention is preferably an "isolated" antibody. When used to describe the antibodies disclosed herein, "isolated" means an antibody that has been identified, separated, and / or recovered from components of its production environment. Preferably, an isolated antibody is free of association with all other components from its production environment. Contaminating components of its production environment, such as those resulting from recombinantly transfected cells, are typically substances that may interfere with diagnostic or therapeutic uses of the polypeptide and may include enzymes, hormones, and other proteinaceous or non-proteinaceous solutes. In a preferred embodiment, the antibody can be (1) purified sufficiently to obtain at least 15 residues of N-terminal or internal amino acid sequence using a spinning cup sequenator, or (2) purified to homogeneity by SDS-PAGE under non-reducing or reducing conditions using Coomassie blue, or preferably silver staining. Ordinarily, however, an isolated antibody can be prepared by at least one purification step.

[0084] As used herein, the term "position" refers to the position of an amino acid within an amino acid sequence described herein. Also, as used herein, the term "corresponding" includes that the position is not solely determined by the number of preceding nucleotides / amino acids.

[0085] A given amino acid position in the present invention may be substituted by deletion or addition of amino acids elsewhere in the polypeptide.

[0086] Thus, under "corresponding positions" in the present invention, it is understood that amino acids may differ in the indicated number and still have similar adjacent amino acids. Also, said amino acids that may be replaced, deleted or added are included in the term "corresponding positions".

[0087] To determine whether an amino acid residue in a given amino acid sequence corresponds to a particular position in an amino acid sequence, one skilled in the art can use means and methods known in the art, such as alignment, either manually or by using a computer program such as BLAST 2.0, which stands for Basic Local Alignment Search Tool, or ClustalW, or any other suitable program suitable for generating sequence alignments.

[0088] As used herein, the term "% identity" refers to the percentage of identical amino acid residues at corresponding positions in two amino acid sequences when comparing them in optimal sequence alignment, as exemplified by the ClustalW or X technology available at www.clustal.org, or equivalent technology. That is, both sequences (reference and subject sequences) are aligned, identical amino acid residues between both sequences are identified, and the total number of identical amino acids is divided by the total number of amino acids (amino acid length). The result of this division is a percentage value, i.e., percent identity value / degree.

[0089] In another aspect, the invention provides an antibody, or antigen-binding portion thereof, of the invention for use as a diagnostic composition, i.e., the antibody, or antigen-binding portion thereof, can be used in a diagnostic assay for the antigen, e.g., to detect its expression in specific cells, tissues, or serum.

[0090] A variety of diagnostic assay techniques known in the art can be used, including competitive binding assays, direct or indirect sandwich assays, and immunoprecipitation assays, performed in either heterogeneous or homogeneous phases (Zola, Monoclonal Antibodies: A Manual of Techniques, CRC Press, Inc. (1987) pp. 147-158). The antibodies or antigen-binding portions thereof used in diagnostic assays can be labeled with a detectable moiety. For example, the antibodies or antigen-binding portions thereof may be modified with detectable markers, including ligand groups (e.g., biotin), fluorophores and chromogens, radioisotopes, electron-dense reagents, or enzymes. Enzymes are detected by their activity. For example, horseradish peroxidase is detected by its ability to convert tetramethylbenzidine (TMB) to a blue pigment that is quantifiable by a spectrophotometer. Other suitable binding partners include biotin and avidin, IgG and protein A, and other receptor-ligand pairs known in the art.

[0091] The detectable moiety should be capable of producing, either directly or indirectly, a detectable signal. For example, the detectable moiety can be, for example, 3 H, 14 C. 32 P, 35 S, or 125 The detectable moiety may be a radioisotope such as I, a fluorescent or chemiluminescent compound such as fluorescein isothiocyanate, rhodamine, or luciferin, or an enzyme such as alkaline phosphatase, β-galactosidase, or horseradish peroxidase. Any method known in the art for conjugating an antibody to a detectable moiety can be used.

[0092] When administered to a subject, the antibody or antigen-binding portion thereof of the invention is preferably in the form of a composition. The composition is preferably suitable for pharmaceutical use and administration to a subject.

[0093] Thus, the antibodies, or antigen-binding portions thereof, of the invention are contemplated for use in diagnostics.Thus, the invention contemplates pharmaceutical compositions (or medicaments) comprising the antibodies, or antigen-binding portions thereof, described herein.

[0094] In yet other embodiments, the invention provides methods of treating a subject with cancer comprising administering a therapeutically effective amount of an antibody, or antigen-binding portion thereof, of the invention.

[0095] As used herein, "cancer" refers to a broad group of diseases characterized by the uncontrolled growth of abnormal cells in the body.
