The .xml file, created on February 9, 2023, is named PC072799 Sequence Listing.xml and is 252KB in size." [Background technology]

[0003] background The present invention relates to antibodies that specifically bind to one or more of IL-4, IL-13, IL-33, TSLP, and p40, as well as compositions, methods, and uses thereof, for the treatment and prevention of one or more symptoms associated with the respective diseases or conditions, including atopic dermatitis, asthma, cancer, COPD, food allergies, allergic rhinitis, eosinophilic esophagitis, chronic rhinosinusitis with nasal polyps, alopecia areata, prurigo nodularis, keloids, bullous pemphigoid, chronic urticaria, IPF, scleroderma, and the like. and uses of the antibodies of the present disclosure to treat one or more diseases or conditions selected from the group consisting of systemic sclerosis, diabetic kidney disease, Behcet's disease, gout, Alzheimer's disease, atherosclerosis, fungal keratitis, non-alcoholic steatohepatitis (NASH), psoriasis, psoriatic arthritis, Crohn's disease, ulcerative colitis, allergies, alopecia, idiopathic pulmonary fibrosis, systemic sclerosis, keloids, systemic lupus erythematosus (SLE), primary biliary cirrhosis, and hidradenitis suppurativa.

[0004] IL-4 and IL-13 are key drivers of immune activation, leading to inflammation, edema, fibrosis, and pruritus in atopic disorders (48, 49). IL-4 and IL-13 interact with cells through a common receptor, consisting of IL-4Rα and IL-13Rα1 (type II receptor), expressed on monocytes, fibroblasts, keratinocytes, epithelial cells, smooth muscle cells, and other non-lymphoid cell types (29). IL-4 can also activate cells through the common IL-4Rα / IL-2Rγ (type I receptor) expressed on T cells, B cells, and monocytes. Engagement of IL-4Rα through either receptor activates STAT6 and induces atopy-related genes (29). Although IL-4 and IL-13 may share common receptors and signaling pathways, differences in cytokine availability, localization, and receptor binding affinity result in distinct response profiles (49, 50). Further differentiation can arise from the type I receptor (IL-4Rα / γc) ( 51 ), which drives Th2 differentiation via IL-4 but not IL-13, and the cell surface “decoy” IL-13Rα2, which mediates neutralization and depletion of IL-13 but not IL-4 ( 52 , 53 ).

[0005] The role of IL-4 and IL-13 in atopic disease is supported by genetic associations, extensive validation in preclinical models, and the clinical efficacy of IL-4 and IL-13 neutralization in a range of atopic indications (48). The anti-IL-4Rα drug Dupixent® (dupilumab, Sanofi / Regeneron) blocks responses to both cytokines and has been approved for the treatment of moderate to severe atopic dermatitis (AD), asthma, and chronic rhinosinusitis with nasal polyposis, demonstrating the activity of IL-4 and IL-13 in these indications (54-56). The anti-IL-13 mAbs lebrikizumab (Lilly) (57) and tralokinumab (Adbry™, Leo Pharma) (58, 59) have also demonstrated efficacy in AD, with more limited activity in asthma (60, 61). The efficacy of anti-IL-13 mAbs in AD suggests a key role for IL-13 neutralization in the efficacy of Dupixent®. Nevertheless, available meta-analyses (62, 63) suggest that Dupixent® has superior activity to lebrikizumab and tralokinumab, consistent with the additional benefit of IL-4 blockade.

[0006] IL-33 is passively released during cell necrosis or upon tissue injury, suggesting that it may function as an alarmin to modify the immune system after endothelial or epithelial cell damage during infection, physical stress, or trauma. IL-33 plays an important role in type 2 innate immunity through the activation of eosinophils, basophils, mast cells, macrophages, and group 2 innate lymphoid cells (ILC2s), which are associated with allergic inflammation, via its receptor ST2 (96).

[0007] Thymic stromal lymphopoietin (TSLP) is an epithelial cytokine important in the initiation and maintenance of inflammation. Tezspire® (tezepelumab, Amgen) is a TSLP antibody approved for the treatment of asthma.

[0008] IL-4 and IL-13 are primarily associated with type 2 effector responses. In contrast, IL-12 and IL-23 are involved in type 1 and type 3 (Th17) responses, respectively (77). IL-12 drives T helper 1 (Th1) cell differentiation and interferon-γ (IFN-γ) production, while IL-23 promotes the maintenance of Th17 cells, which produce IL-17 and other type 3 cytokines. Type 1 and type 3 responses are involved in a range of human inflammatory and autoimmune diseases. A causal role for IL-12p40-containing cytokines has been established through the approval of numerous drugs (75) (IL-12p40 will hereafter be referred to simply as p40). The p40 neutralizer Stelara® (ustekinumab, Janssen) neutralizes both IL-12 and IL-23 and is approved for the treatment of plaque psoriasis, psoriatic arthritis, Crohn's disease, and ulcerative colitis. The IL-23-selective anti-IL-23p19 blockers Tremfya® (guselkumab, Janssen), Skyrizi® (risankizumab, Boehringer Ingelheim / AbbVie), and Ilumya® (tildrakizumab, Sun Pharmaceutical) are approved for a range of psoriatic disorders. Summary of the Invention [Problem to be solved by the invention]

[0009] Despite the efficacy of dupilumab, tezepelumab, guselkumab, risankizumab, and tildrakizumab, there remains an unmet need for safe and effective treatments for the numerous diseases characterized by immune responses that address a wide range of pathogenic mechanisms.

[Brief explanation of the drawings]

[0669] [Figure 1A]Figure 1A shows an exemplary sequence illustrating the Pfabat numbering of the light chain portions of the anti-IL-13 and anti-IL-4 binding arms. Position numbers are displayed vertically in a single column, and dashes ("-") indicate gaps in the alignment. For example, residue L27D of the anti-IL-13 CDR-L1 is His, and the equivalent residue in the anti-IL-4 binding arm is Glu. The CDR positions considered are shown in bold, and the corresponding amino acids are bold and underlined. [Figure 1B] Figure 1 shows an exemplary sequence illustrating the Pfabat numbering of the heavy chain portions of the anti-IL-13, anti-IL-4, and anti-IL-33 binding arms. Position numbers are displayed vertically in a single column, and dashes ("-") indicate gaps in the alignment. For example, residue H100C of anti-IL-4 CDR-L1 is Phe, and the anti-IL-13 binding arm, which has a shorter CDRH3, does not have a corresponding residue. The CDR positions considered are shown in bold, and the corresponding amino acids are bold and underlined. The anti-IL-13 heavy chain fragments used in most multispecific antibody sequences do not contain a complete hinge or Fc. The Pfabat algorithm numbers the sequences as independent Fab domains and does not number the small upper hinge fragment ("EPKSC" (SEQ ID NO: 102)), which is manually included for reference (lower case, positions H226-H230). [Figure 2] Figure 2 shows a graph summarizing the results of LC / MS analysis of the IL4-1285 antibody. It reveals that post-translational modifications are located on the light chain. Mass analysis of peak 1 (P1) relative to peak 2 (P2) reveals an 80 Dalton (Da) species with a mass of 23755.0 Da present in P2. P1 refers to the isolated "main peak" species (after LysC + TCEP) as analyzed by ion-exchange purification and detected using light-chain LC / MS analysis. P2 refers to "peak 2" (after LysC + TCEP) as isolated by ion-exchange purification and detected using light-chain LC / MS analysis. Peak 2 has an additional sulfation on Tyr (L27a), resulting in an 80 Da shift in MS. [Figure 3] Figure 3 shows a graph comparing LC / MS analysis of the IL4-1346 (hu3B9-VLv2.8) [lower two panels] and IL4-1285 (hu3B9-VLv2.0) antibody light chains [upper two panels]. O-linked sulfation of the light chain CDR1 peptide (DRVTITCKASQSVDY) was identified by LC / MS analysis, and the Y(L27d)F mutation eliminated heterogeneity. The left panels (top and bottom) show peptide-level mapping data (AspN enzyme). The right panels (top and bottom) show subunit mapping using the LysC method. Peptide mapping (AspN digestion) shows that the DFD light chain contains no sulfation, while the DYD light chain has some sulfation (at +79.9568 Da) in the upper left spectrum. Subunit analysis shows that the DFD light chain has no sulfated species (upper right spectrum) and the DYD light chain has several sulfated Da species (lower right spectrum). [Figure 4] FIG. 4 depicts the changes incorporated into IL4-1359 (VH1 G07_VLv2.9) VH CDRH1 that contribute to higher affinity for IL-4. [Figure 5] FIG. 5 depicts changes at Tyr(L27d)E that can be made to remove the O-sulfation post-translational modification and further stabilize the IL-4 / IL4-1285 (RA1-2 or hu3B9-VLv2.0) interface.

[Figure 9] FIG. 9 is a diagram depicting how the presence of serine at residue 30 in IL13-1307 (hu13.4) CDRH1 contributes to its higher affinity for IL-13 compared to IL13-1283 (IMA-638 or hu13.2). [Figure 10] Figure 10 is a diagram depicting how the aspartic acid at position 55 in IL13-1307 (hu13.4) CDRH2, instead of the glycine at this position in IL13-1283, contributes to the higher affinity for IL-13 compared to IL13-1283 (IMA-638 or hu13.2). [Figure 11] FIG. 11 depicts how the changes engineered into IL13-0001 (1RVHC9-VLA4) VH CDRH3 contribute to higher affinity for IL-13. [Figure 12] FIG. 12 depicts how the changes engineered into IL13-0001 (1RVHC9-VLA4) VL CDRL1 contribute to higher affinity for IL-13. [Figure 13] FIG. 13 depicts a graph showing how increasing potency of IL-33 neutralization correlates with increasing polyreactivity.

[0673] definition Unless otherwise defined, all technical terms, notations, and other scientific terms or terminology used herein are intended to have the meanings commonly understood by those skilled in the art to which this invention belongs. For example, the term "and / or" used herein in a phrase such as "A and / or B" is intended to include both A and B, A or B, A (alone), and B (alone). Similarly, the term "and / or" used in a phrase such as "A, B, and / or C" is intended to encompass each of the following embodiments: A, B, and C, A, B, or C, A or C, A or B, B or C, A and C, A and B, B and C, A (alone), B (alone), and C (alone). In some cases, terms having commonly understood meanings are defined herein for clarity and / or ready reference, and the inclusion of such definitions herein should not necessarily be interpreted as representing a substantial difference from what is commonly understood in the art.

[0674] As used herein, the singular forms "a," "an," and "the" include their corresponding plural referents unless the context clearly dictates otherwise.

[0675] As used herein, numerical ranges are inclusive of the numbers defining the range.

[0676] Reference herein to "about" a value or parameter includes (and describes) embodiments directed to the value or parameter itself, as well as values ​​or parameters that may be less than or greater than the stated numerical value for that parameter by as much as 10%. For example, a dose of "about 5 mg / kg" includes 5 mg / kg, and also includes any value between 4.5 mg / kg and 5.5 mg / kg. When the term "about" is used in the context of a period of time (years, months, weeks, days, etc.), it means that period of time plus or minus some amount of the next subperiod (e.g., about 1 year means 11-13 months, about 6 months means 6 months plus or minus 1 week, about 1 week means 6-8 days, etc.), or within 10 percent of the stated value, whichever is longer.

[0677] "Antibody" refers to an immunoglobulin molecule capable of specifically binding to a target, e.g., a polypeptide, carbohydrate, polynucleotide, lipid, etc., via at least one antigen-binding site located in the variable region of the immunoglobulin molecule. As used herein, the term "antibody" can encompass any type of antibody (e.g., monospecific, bispecific, trispecific, multispecific), and includes portions of intact antibodies that retain the ability to bind to a given antigen (e.g., "antigen-binding fragments"), and any other modified configuration of an immunoglobulin molecule that contains an antigen-binding site.

[0678] Antibodies include antibodies of any class, e.g., IgG, IgA, or IgM (or subclasses thereof); antibodies are not required to be of any particular class. Depending on the antibody amino acid sequence of the constant region of its heavy chain (HC), immunoglobulins can be assigned to different classes. There are five major classes of immunoglobulins: IgA, IgD, IgE, IgG, and IgM, some of which can be further divided into subclasses (isotypes), e.g., IgG1, IgG2, IgG3, IgG4, IgA1, and IgA2. The heavy chain constant regions corresponding to the different classes of immunoglobulins are called alpha, delta, epsilon, gamma, and mu, respectively. The subunit structures and three-dimensional configurations of different classes of immunoglobulins are well known.

[0679] Examples of antibody antigen-binding fragments and modified configurations include (i) Fab fragments (monovalent fragments consisting of the VL, VH, CL, and CH1 domains); (ii) F(ab')2 fragments (bivalent fragments containing two Fab fragments linked by a disulfide bridge at the hinge region), and (iii) Fv fragments consisting of the VL and VH domains of a single antibody arm. Furthermore, the two domains of the Fv fragment, VL and VH, are encoded by separate genes, but can be joined using recombinant methods by a synthetic linker that allows the VL and VH domains to be produced as a single protein chain that pairs to form a monovalent molecule (known as single-chain Fv (scFv)). See, for example, Bird et al., Science 1988, 242:423-426 and Huston et al., Proc. Natl. Acad. Sci. 1988 USA 85:5879-5883. Other forms of single chain antibodies, such as diabodies, are also encompassed.

[0680] Additionally, antibodies in which the C-terminal lysine (K) amino acid residue is missing in the heavy chain polypeptide are further encompassed (e.g., human IgG1 heavy chains contain a terminal lysine). As is known in the art, the C-terminal lysine may be trimmed during antibody production, resulting in an antibody having a heavy chain lacking the C-terminal lysine. Alternatively, the antibody heavy chain may be produced using nucleic acid that does not contain the C-terminal lysine.

[0681] The "variable region" of an antibody refers to the variable region of the antibody light chain or the variable region of the antibody heavy chain, either alone or in combination. As is known in the art, the variable regions of the heavy and light chains, also known as hypervariable regions, are each composed of four framework regions (FRs) connected by three complementarity-determining regions (CDRs), which contribute to the formation of the antigen-binding site of the antibody. When a variant of a subject variable region is desired, particularly one with substitutions of amino acid residues outside the CDR regions (i.e., in the framework regions), appropriate amino acid substitutions, preferably conservative amino acid substitutions, can be identified by comparing the subject variable region with the variable regions of other antibodies containing the same standard class CDR1 and CDR2 sequences as the subject variable region (Chothia and Lesk, J Mol Biol 196(4):901-917, 1987).

[0682] In certain embodiments, the final delineation of CDRs and identification of the residues comprising the antibody binding site are achieved by solving the structure of the antibody or the structure of an antibody-ligand complex. In certain embodiments, this can be achieved by any of a variety of techniques known to those skilled in the art, such as X-ray crystallography. In certain embodiments, various methods of analysis can be used to identify or predict CDR regions. In certain embodiments, various methods of analysis can be used to identify or predict CDR regions. Examples of such methods include, but are not limited to, the Kabat definition, the Chothia definition, the AbM definition, the contact definition, the conformational definition, and the Pfabat numbering system shown in Example 1.

[0683] The Kabat definition is a standard for numbering residues in antibodies and is often used to identify CDR regions. See, e.g., Johnson and Wu, 2000, Nucleic Acids Res., 28:214-8. The Chothia definition is similar to the Kabat definition, but takes into account the location of certain structural loop regions. See, e.g., Chothia et al., 1986, J. Mol. Biol., 196:901-17; Chothia et al., 1989, Nature, 342:877-83. The AbM definition uses an integrated suite of computer programs created by the Oxford Molecular Group to model antibody structure. See, e.g., Martin et al., 1989, Proc Natl Acad Sci (USA), 86:9268-9272, "AbM™, A Computer Program for Modeling Variable Regions of Antibodies," Oxford, UK, Oxford Molecular, Ltd. The AbM definition models the tertiary structure of antibodies from primary sequence using a knowledge database and a combination of initial methods, such as those described by Samudrala et al., 1999, "Ab Initio Protein Structure Prediction Using a Combined Hierarchical Approach," PROTEINS, Structure, Function and Genetics Suppl. 3:194-198. The contact definition is based on an analysis of available crystal structures of complexes. See, e.g., MacCallum et al., 1996, J. Mol. Biol., 5:732-45. In another approach, referred to herein as "conformational definition" of CDRs, CDR positions can be identified as residues that contribute enthalpic contributions to antigen binding. See, e.g., Makabe et al., 2008, Journal of Biological Chemistry, 283:1156-1166.Still other CDR boundary definitions may not strictly follow one of the above approaches, but nevertheless overlap with at least a portion of the Kabat CDRs, while they may be shortened or extended to take into account predicted or experimental findings that particular residues or groups of residues do not significantly affect antigen binding. The numbering system used in this application is the Pfabat numbering system shown in Example 1.

[0684] As used herein, CDR can refer to CDRs defined by any method known in the art, including a combination of methods. The method used herein can utilize CDRs defined according to any of these methods. For any given embodiment that contains two or more CDRs, the CDRs can be defined according to any one or more of Kabat, Chothia, extended, AbM, contact, conformational definition, or Pfabat method. The antibodies of the present application are numbered according to a modified version of the Kabat numbering system, which is shown in more detail in Example 1.

[0685] The term "hinge region," as used herein, includes its meaning known in the art, as set forth in, for example, Janeway et al., ImmunoBiology: the immune system in health and disease, Elsevier Science Ltd., NY (4th ed., 1999), Bloom et al., Protein Science, 6:407-415, 1997, and Humphreys et al., J. Immunol. Methods, 209:193-202, 1997.

[0686] The "constant region" of an antibody refers to the constant region of the antibody light chain or the constant region of the antibody heavy chain, either alone or in combination. The IgG heavy chain constant region contains three consecutive immunoglobulin domains (CH1, CH2, and CH3) with a hinge region between the CH1 and CH2 domains. The IgG light chain constant region contains a single immunoglobulin domain (CL).

[0687] "Fc domain" refers to the portion of an immunoglobulin (Ig) molecule that correlates with the crystallizable fragment obtained by papain digestion of the Ig molecule. As used herein, this term refers to the constant regions of the two chains of an antibody, each chain excluding the first constant region immunoglobulin domain. Within the Fc domain, there are two "Fc chains" (e.g., "first Fc chain" and "second Fc chain"). "Fc chain" generally refers to the C-terminal portion of an antibody heavy chain. Thus, the Fc chain refers to the last two constant region immunoglobulin domains (CH2 and CH3) of IgA, IgD, and IgG heavy chains, and the last three constant region immunoglobulin domains of IgE and IgM heavy chains, and optionally, a flexible hinge N-terminal to these domains.

[0688] Although the boundaries of the Fc chain might vary, the human IgG heavy chain Fc chain is usually defined to include residues C226 or P230 to the carboxyl terminus, where numbering is according to the EU index of Edelman et al., Proc. Natl. Acad. Sci. USA 1969;63(1):78-85, and as described in Kabat et al., 1991. Typically, an Fc chain includes amino acid residues from about 236 to about 447 of the human IgG1 heavy chain constant region. "Fc chain" can refer to this polypeptide in isolation or in the context of a larger molecule (e.g., an antibody heavy chain or an Fc fusion protein).

[0689] A "functional" Fc domain refers to an Fc domain that possesses at least one effector function of a native-sequence Fc domain. Exemplary "effector functions" include C1q binding, complement-dependent cytotoxicity (CDC), Fc receptor binding, antibody-dependent cell-mediated cytotoxicity (ADCC), phagocytosis, down-regulation of cell surface receptors (e.g., B cell receptors), and B cell activation. Such effector functions generally require combining the Fc domain with a binding domain (e.g., an antibody variable region) and can be assessed using a variety of assays known in the art for evaluating such antibody effector functions.

[0690] A "native sequence" Fc chain or "wild-type Fc chain" refers to an Fc chain comprising an amino acid sequence identical to that of an Fc chain found in nature. A "variant" Fc chain comprises an amino acid sequence that differs from that of a native sequence Fc chain by at least one amino acid modification that still retains at least one effector function of the wild-type Fc chain. In some embodiments, a variant Fc chain has at least one amino acid substitution compared to the wild-type Fc chain, e.g., about one to about ten amino acid substitutions, preferably about one to about five amino acid substitutions, in the wild-type Fc chain. A variant Fc chain herein preferably has at least about 80% sequence identity with the wild-type Fc chain, most preferably at least about 90% sequence identity thereto, more preferably at least about 95%, at least about 96%, at least about 97%, at least about 98%, or at least about 99% sequence identity thereto. In some embodiments, the Fc chain comprises part or all of a wild-type hinge region (generally at its N-terminus). In some embodiments, the Fc polypeptide does not comprise a functional or wild-type hinge region.

[0691] nomenclature The antibody domains disclosed herein may be prefixed with an indication of the particular target antigen with which the domain is most closely associated. The prefixes are added merely to provide clarity of shorthand when distinguishing between the different domains listed throughout this disclosure and do not replace or contradict the actual function or structure of the various domains. For example, IL4-VH refers to the variable heavy domain of an antibody containing a CDR capable of specifically binding IL-4. IL4-CH1 refers to the CH1 domain located C-terminal to the IL-4 variable domain, regardless of whether that variable domain is the variable light domain (IL4-VL) or the variable heavy domain (IL4-VH). As described throughout this disclosure, domains of the antibodies of the present disclosure may be combined or fused with domains from other antibodies. Thus, for example, an IL4-VH may be present on a polypeptide chain with an IL13-VL, each independently or together, in the same antibody, and both polypeptides may be referred to as IL4-VH and IL13-VL (see, e.g., Figure 18). Again, by way of example, a polypeptide with an IL4-VH is any polypeptide that includes an IL4-VH domain, i.e., a VH domain that includes a CDR that specifically binds IL-4. A polypeptide with an IL4-VH may include a hinge region, a CH1 domain, a CH2 domain, and a CH3 domain, as in a standard IgG format, or may include various domains described herein, e.g., IL13-VL, together with a CH1 and CL domain fused to either the IL4-VH or IL13-VL (see Figure 18 for examples of different combinations of antibody domains). For example, the DFab LC(1)-HC(2) arms of IL41333-1258, IL413TSLP-1024, and IL413P40-0705 (see Figure 18I) comprise, from N- to C-terminus, IL13-VL, CL, a linker, IL4-VH, CH1, CH2, and CH3, respectively, and can both be referred to as a polypeptide having IL4-VH and a polypeptide having IL13-VL.Furthermore, framework regions may be referred to by the target to which their CDRs are specific. For example, the framework region of an IL-4 antibody of the present disclosure may be referred to as an IL4-VL framework or an IL4-VH framework. Those skilled in the art will understand that these designations do not confer or imply any relationship between the framework region and the target to which the CDRs specifically bind. Thus, the IL4-VL framework region may be derived from a human germline DPK9 sequence that is identical to a known human DPK9 germline sequence. This nomenclature is not limited to the specific antibodies exemplified in this paragraph, but applies across all possible antibodies and antibody combinations within this disclosure.

[0692] Antibodies IL13433-1258, IL134TSLP-1024, and IL134p40-0705 can be described as comprising first, second, third, fourth, and fifth polypeptide chains, respectively, where the second polypeptide is comprised, from N-terminus to C-terminus, of: (VL-1)-(CL-1)-(linker)-(VH-2)-(CH1-2)-(second hinge)-(second CH2)-( the fifth polypeptide comprises, from N-terminus to C-terminus, (VH1)-(CL-1), the fourth polypeptide comprises (VL-2)-(CL-2), the first polypeptide comprises, from N-terminus to C-terminus, (VH-3)-(CH1-3)-(first hinge)-(first CH2)-(first CH3), and the third polypeptide comprises (VL-3)-(CL-3). In each case, VL-1 and VH-1 are IL13-VL and IL13-VH, VL-2 and VH-2 are IL4-VL and IL4-VH, and VH-3 and VL-3 are IL33-VH and IL33-VL, or TSLP-VH and TSLP-VL, or p40-VH and p40-VL.

[0693] A "monoclonal antibody" (mAb) refers to an antibody derived from a single copy or clone, including, for example, any eukaryotic, prokaryotic, or phage clone. Monoclonal antibodies are highly specific, being directed against a single antigenic site. Furthermore, in contrast to polyclonal antibody preparations that typically include different antibodies directed against different determinants (epitopes), each monoclonal antibody is directed against a single determinant on an antigen. The modifier "monoclonal" indicates the character of the antibody as being obtained from a substantially homogeneous population of antibodies, but should not be construed as requiring production of the antibody by any particular method. For example, monoclonal antibodies used in accordance with the present invention may be produced by the hybridoma method first described by Kohler and Milstein, 1975, Nature 256:495, or may be produced by recombinant DNA methods, such as those described in U.S. Pat. No. 4,816,567. In another example, the monoclonal antibodies may be isolated from phage libraries, such as those generated using the techniques described in McCafferty et al., 1990, Nature 348:552-554.

[0694] "Human antibody" refers to an antibody having an amino acid sequence corresponding to that of an antibody produced by a human, or produced using any technique for producing a fully human antibody. For example, fully human antibodies can be obtained by using commercially available mice engineered to express specific human immunoglobulin proteins, or by library (e.g., phage, yeast, or ribosome) display techniques to prepare fully human antibodies. This definition of a human antibody specifically excludes humanized antibodies that contain non-human antigen-binding residues.

[0695] A "chimeric antibody" refers to an antibody in which the variable region sequences are derived from one species and the constant region sequences are derived from another species, e.g., the variable region sequences are derived from a murine antibody and the constant region sequences are derived from a human antibody.

[0696] A "humanized" antibody refers to a non-human (e.g., murine) antibody that is a chimeric antibody containing minimal sequence derived from non-human immunoglobulin. Preferably, a humanized antibody is a human immunoglobulin (recipient antibody) in which residues from the recipient's CDRs are replaced by residues from a CDR of a non-human species (donor antibody), e.g., mouse, rat, or rabbit, having the desired specificity, affinity, and capacity. A humanized antibody may comprise residues that are found neither in the recipient antibody nor in the incorporated CDR or framework sequences, but are included to further refine and optimize antibody performance.

[0697] "Antigen" refers to a molecular entity used to immunize an immunocompetent vertebrate to produce antibodies that recognize the antigen, or to screen an expression library (e.g., phage, yeast, or ribosome display library, among others) for antibody selection. As used herein, antigen is referred to more broadly and is generally intended to include the target molecule that is specifically recognized by an antibody, and thus to include fragments or mimetics of the molecule used in the immunization process to raise antibodies or in library screening to select antibodies.

[0698] " Epitope " refers to the area or region of an antigen to which an antibody specifically binds, as determined by any method known in the art, for example, the area or region that contains the residue that interacts with an antibody. For example, as described in Chapter 11 of Harlow and Lane, "Using Antibodies," a Laboratory Manual, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, New York, 1999, there are many methods known in the art for mapping and characterizing the location of epitopes on proteins, including elucidating the crystal structure of antibody-antigen complexes, competitive assays, gene fragment expression assays, epitope mapping, and synthetic peptide-based assays. Additionally or alternatively, during the discovery process, antibody generation and characterization can reveal information about desired epitopes. From this information, it is then possible to competitively screen antibodies for binding to the same epitope.

[0699] As used herein, the term "binding affinity" refers to the strength of the sum of non-covalent interactions between a single binding site of a molecule (e.g., an antibody) and its binding partner (e.g., an antigen). Unless otherwise indicated, as used herein, "binding affinity" refers to the intrinsic binding affinity, which reflects a 1:1 interaction between members of a binding pair (e.g., an antibody and an antigen). The affinity of a molecule X for its partner Y is generally determined by the dissociation constant (K D) The affinity of molecule X for its partner Y can generally be expressed by the dissociation constant (Kd). Affinity can be measured by general methods known in the art, including those described herein. Low affinity antibodies generally bind antigens slowly and tend to dissociate easily, while high affinity antibodies generally bind antigens faster and tend to remain bound longer. Various methods for measuring binding affinity are known in the art, any of which can be used for the purposes of the present invention. In particular, the term "binding affinity" is intended to refer to the dissociation rate of a particular antigen-antibody interaction. K D is the "off rate (k off The rate of dissociation is also called the association rate or "on rate (k on )" Therefore, K D is k off / k on and is expressed as molar concentration (M). D A smaller K results in a stronger binding affinity. Thus, a K of 1 μM D has a K of 1 nM D The antibody shows weaker binding affinity compared to the D The K value can be determined using methods well established in the art. D One method for determining K is by using surface plasmon resonance (SPR), typically using a biosensor system such as a BIACORE system. BIACORE kinetic analysis involves analyzing the binding and dissociation of antigens from chips having immobilized molecules (e.g., molecules containing epitope-binding domains) on their surfaces. D and k, the association and dissociation rate constants, respectively, for determining other ratios. on and k offDetermination of analyte / ligand interaction may be performed using a surface plasmon resonance-based biosensor to characterize analyte / ligand interactions under conditions in which the analyte is monovalent with respect to binding to a ligand immobilized at low volume on the sensor surface via a capture reagent, for example. Analysis may be performed using the kinetic titration methodology described, for example, in Karlsson et al., Anal. Biochem 349, 136-147, 2006, or using multi-cycle kinetic analysis. The sensor chip, capture reagent, and assay buffer used for a given assay are selected to provide stable capture of the ligand on the sensor surface, minimize nonspecific binding of the analyte to the surface, and provide an appropriate analyte binding response for kinetic analysis, in accordance with the recommendations of Myszka, J. Mol. Recognit 12, 279-284, 1999. The analyte binding response for each analyte / ligand interaction is double-referenced and expressed as a global parameter, k, as described by Myszka and Morton et al., Biophys. Chem 64, 127-137 (1997). a , k d and R max The equilibrium dissociation constant, K, is fitted to a 1:1 Langmuir "mass transport limited model" using D is the ratio of kinetic rate constants K D =k off / k on Such determinations are preferably made at 25°C or 37°C. Typically, the rate constant (k on or k a and k off or k d ) and equilibrium dissociation constants are measured using whole antibodies and monomers. D Another method for determining .DELTA. is by using biolayer interferometry, typically using OCTET™ technology (Octet QK e Alternatively, or in addition, one can use the KinExA (Kindex Exclusion Assay) assay available from Sapidyne Instruments (Boise, ID).

[0700] As used herein, the terms "immunospecifically bind," "immunospecifically recognize," "specifically bind," "specifically recognize," and similar terms refer to a molecule, e.g., a binding domain, that specifically binds to an antigen (e.g., an epitope or immune complex) and does not specifically bind to another molecule. A molecule that specifically binds to an antigen may bind to other peptides or polypeptides with lower affinity, as determined by assays known in the art, e.g., immunoassays, BIACORE™, or other assays. Preferably, a molecule that specifically binds to an antigen does not cross-react with other proteins.

[0701] The terms "specific binding" or "specifically binds," when used in reference to the interaction of an antibody and a protein or peptide, refer to an interaction that is dependent on the presence of a particular structure (i.e., an antigenic determinant or epitope) on the protein; in other words, the antibody recognizes and binds to a specific protein structure, rather than proteins in general. For example, if an antibody is specific for epitope "A," the presence of a protein containing epitope A (or free, unlabeled A) in a reaction containing labeled "A" and the antibody will reduce the amount of labeled A bound to the antibody.

[0702] In certain embodiments, "specifically binds" means, for example, that the antibody binds specifically to an antibody with a K of about 0.1 nM or less, more usually less than about 1 μM. D In certain embodiments, "specifically binds" means that the antibody binds to a protein with a K of at least about 0.1 μM or less in some cases, at least about 0.01 μM or less in other cases, and at least about 1 nM or less in other cases. DSpecific binding means binding to a target at a specific site. Due to sequence identity between homologous proteins in different species, specific binding can include antibodies that recognize proteins in more than one species. Similarly, due to homology within certain regions of the polypeptide sequences of different proteins, specific binding can include antibodies that recognize more than one protein. It is understood that in certain embodiments, an antibody or binding moiety that specifically binds to a first target may or may not specifically bind to a second target. Thus, "specific binding" does not necessarily require (but can include) exclusive binding, i.e., binding to a single target. Thus, in some embodiments, an antibody may specifically bind to more than one target. In certain embodiments, multiple targets may bind to the same antigen-binding site on the antibody. For example, in certain instances, an antibody may contain two identical antigen-binding sites, each of which specifically binds to the same epitope on more than one protein. In certain alternative embodiments, an antibody may be multispecific and contain at least two antigen-binding sites with different specificities. As a non-limiting example, a bispecific antibody may contain one antigen-binding site that recognizes an epitope on one protein and may further contain a second, different antigen-binding site that recognizes a different epitope on a second protein. Generally, but not necessarily, reference to binding refers to specific binding.

[0703] An antibody that specifically binds to an antigen may bind other peptides or polypeptides with lower affinity, as determined by assays known in the art, e.g., immunoassays, BIACORE™, or other assays. Preferably, an antibody that specifically binds to an antigen does not cross-react with other proteins.

[0704] The terms "non-specific binding" or "background binding," when used in reference to the interaction of an antibody and a protein or peptide, refer to an interaction that is not dependent on the presence of a specific structure (i.e., the antibody generally binds to the protein, rather than to a specific structure such as an epitope).

[0705] A neutralizing or "blocking" antibody refers to an antibody whose binding to one or more selected from the group consisting of IL-4, IL-13, IL-33, TSLP, and p40 either or both (i) prevents, limits, or inhibits the interaction between IL-4, IL-13, IL-33, TSLP, and p40, respectively, and a suitable ligand, or (ii) results in inhibition of at least one biological function of IL-4, IL-13, IL-33, TSLP, or p40 binding, as appropriate. Assays for determining neutralization by antibodies of the present disclosure are well known in the art.

[0706] As used herein, an "antibody that binds" to a target, an "antibody that recognizes" a target, an "antibody that specifically binds" to a target, an "anti-target antibody," an "anti-target antibody molecule," a "targeting antibody," and the like, include molecules that contain at least one binding domain that specifically binds to a target.

[0707] A "monospecific antibody" refers to an antibody that contains one or more antigen-binding sites per molecule, such that every single antibody binding site specifically recognizes the same epitope on the antigen. Thus, in instances where a monospecific antibody has two or more antigen-binding sites, the binding sites compete with each other for binding to a single antigen molecule.

[0708] A "bispecific antibody" refers to a molecule that has binding specificities for at least two different epitopes. In some embodiments, a bispecific antibody can simultaneously bind to two different antigens. In other embodiments, the two different epitopes may be present on the same antigen.

[0709] As used herein, a "trispecific antibody" is an antibody that has binding specificities for three different epitopes. In some embodiments, a trispecific antibody can simultaneously bind to three different antigens. In other embodiments, the three different epitopes may be present on the same antigen.

[0710] As used herein, a "multispecific antibody" is an antibody that has binding specificities for at least two different epitopes. In some embodiments, a multispecific antibody can simultaneously bind to at least two different antigens. In other embodiments, the at least two different epitopes may be present on the same antigen.

[0711] As used herein, the term "IL-4 / IL-13 / IL-33 trispecific antibody" or "IL-4 / IL-13 / IL-33 multispecific antibody" refers to a molecule designed to specifically bind to IL-4, IL-13, and IL-33. As used herein, the term "IL-4 / IL-13 / TSLP trispecific antibody" or "IL-4 / IL-13 / TSLP multispecific antibody" refers to a molecule designed to specifically bind to IL-4, IL-13, and TSLP. As used herein, the term "IL-4 / IL-13 / p40 trispecific antibody" or "IL-4 / IL-13 / p40 multispecific antibody" refers to a molecule designed to specifically bind to IL-4, IL-13, and p40.

[0712] Half-maximal effective concentration (EC 50 The term "EC" refers to the concentration of a therapeutic agent that causes a response halfway between baseline and maximum after a specified exposure time. A therapeutic agent may cause inhibition or stimulation. 50 The value is commonly used as a measure of efficacy and is used herein.

[0713] Inhibitory concentration (IC 50The term "IC" refers to the concentration of an inhibitor at which 50% of the inhibition in its activity is achieved. A therapeutic agent may cause either inhibition or stimulation. 50 The value is commonly used as a measure of efficacy and is used herein.

[0714] "Agonist" refers to a substance that promotes (i.e., induces, causes, enhances, or increases) the biological activity or effect of another molecule. The term agonist includes substances (such as antibodies) that bind to a molecule and promote the activity of that molecule.

[0715] "Antagonist" refers to a substance that prevents, blocks, inhibits, neutralizes, or reduces the biological activity or effect of another molecule, such as a receptor. The term antagonist includes substances (such as antibodies) that bind to a molecule and prevent or reduce the activity of that molecule.

[0716] The term "compete," as used herein with respect to antibodies, means that a first antibody binds to an epitope in a manner sufficiently similar to that of a second antibody such that the resultant binding of the second antibody to its cognate epitope is detectably reduced in the presence of the first antibody compared to binding of the second antibody in the absence of the first antibody. Binding of the first antibody to its epitope may, but need not, also be detectably reduced in the presence of the second antibody. That is, a first antibody can inhibit binding of a second antibody to its epitope without the second antibody inhibiting binding of the first antibody to its respective epitope. However, if each antibody detectably inhibits binding of the other antibody to its cognate epitope or ligand, whether to the same, a greater, or a lesser extent, the antibodies are said to "cross-compete" with each other for binding of their respective epitopes. Both competing and cross-competing antibodies are encompassed by the present invention. Regardless of the mechanism by which such competition or cross-competition occurs (e.g., steric hindrance, conformational changes, or binding to a common epitope or portion thereof), one of skill in the art will recognize, based on the teachings provided herein, that such competing or cross-competing antibodies can be encompassed and useful in the methods disclosed herein.

[0717] A "host cell" refers to an individual cell or cell culture that can be or has been a recipient for a vector for incorporation of a polynucleotide insert. A host cell includes the progeny of a single host cell, which progeny may not necessarily be completely identical (in morphology or genomic DNA complement) to the original parent cell due to natural, accidental, or deliberate mutation. A host cell includes cells transfected in vivo with a polynucleotide of the invention.

[0718] A "vector" refers to a construct capable of delivering, and preferably expressing, one or more genes or sequences of interest (e.g., antibody-encoding genes) in a host cell. Examples of vectors include, but are not limited to, plasmids and viral vectors, and may include naked nucleic acids or nucleic acids associated with delivery-assisting materials (e.g., cationic condensing agents, liposomes, etc.). A vector may contain DNA or RNA. As used herein, an "expression vector" refers to a vector containing at least one polypeptide-encoding sequence and at least one regulatory element (e.g., promoter sequence, poly(A) sequence) associated with the transcription or translation of the gene. Typically, a vector used herein contains at least one antibody-encoding gene and one or more regulatory elements or selectable markers. Vector components may include, for example, one or more of the following: a signal sequence, an origin of replication, one or more marker genes, and appropriate transcription control elements (such as promoters, enhancers, and terminators). For translation, the one or more translational control elements may also include, for example, a ribosome binding site, a translation initiation site, and a stop codon.

[0719] An "isolated" molecule (e.g., an isolated antibody) refers to a molecule that, depending on its source of origin or derivatization, (1) is not associated with naturally associated components with which it is natively associated; (2) is substantially free of other molecules from the same source, e.g., species, cell in which it is expressed, library, etc.; (3) is expressed by cells from a different species; or (4) does not occur in nature. Thus, a chemically synthesized molecule or a molecule expressed in a cellular system different from the system from which it naturally originated is "isolated" from its naturally associated components. A molecule may also be rendered substantially free of naturally associated components by isolation, using purification techniques well known in the art.

[0720] As used herein, the term "linker" refers to an amino acid sequence of two or more amino acids in length. The linker may be composed of neutral polar or nonpolar amino acids. The linker may be, for example, 2 to 100 amino acids in length, e.g., between 2 and 50 amino acids in length, e.g., 3, 4, 5, 6, 8, 10, 12, 15, 20, 25, 30, 35, 40, 45, or 50 amino acids in length. The linker may be "cleavable," e.g., by self-cleavage or enzymatic or chemical cleavage. Cleavage sites in the amino acid sequence, as well as enzymes and chemicals that cleave at such sites, are well known in the art and are described herein. In some embodiments, the linker comprises one or more repeating units of a sequence containing glycine and serine residues. In some embodiments, the linker comprises one or more repeating units of G4S. In some embodiments, the linker comprises (G4S) 1~3 In some embodiments, the linker is GGGGS (SEQ ID NO: 10).

[0721] As used herein, the term "disulfide bond" or "cysteine-cysteine ​​disulfide bond" refers to a covalent interaction between two cysteines, in which the sulfur atoms of the cysteines are oxidized to form a disulfide bond. The average bond energy of a disulfide bond is approximately 60 kcal / mol, compared to 1-2 kcal / mol for a hydrogen bond. In the context of the present invention, the cysteines that form the disulfide bond are located within the framework region of a single-chain antibody and serve to stabilize the antibody conformation. Cysteine ​​residues can be introduced, for example, by site-directed mutagenesis, to create a stabilizing disulfide bond within the molecule.

[0722] As used herein, the terms "linked," "fused," and "fusion" are used interchangeably and refer to the joining of more than two elements or components together by whatever means, including chemical conjugation or recombinant means.

[0723] As used herein, the term "covalently linked" means that the specified moieties are either directly covalently bonded to one another or indirectly covalently joined to one another through one or more intervening moieties, such as linking peptides or moieties.

[0724] As used herein, the term "connected" refers to the covalent linkage or attachment of two or more proteins, polypeptides, or fragments thereof, via their respective peptide backbones. For example, one polypeptide may be connected to another polypeptide by genetic expression of a single polynucleotide molecule that encodes these two polypeptides in frame. Such a genetic fusion results in the expression of a single, continuous protein comprising both polypeptides.

[0725] As used herein, the term "modification" refers to the substitution, insertion, or deletion of an amino acid in a polypeptide sequence, a change to a moiety chemically linked to a protein, or a change to the function of a protein, such as an antibody. For example, the modification may be a change to the function of an antibody or a change to a carbohydrate structure attached to a protein. As used herein, "amino acid modification" refers to the mutation (substitution), insertion (addition), or deletion of one or more amino acid residues in an antibody. The term "amino acid mutation" refers to the replacement of at least one existing amino acid residue with another different amino acid residue (e.g., replacing an amino acid residue). The term "amino acid deletion" refers to the removal of at least one amino acid residue at a given position in the amino acid sequence. For example, the mutation L234A indicates that the amino acid residue lysine at position 234 in the antibody Fc region is replaced with the amino acid residue alanine (lysine replaced with alanine) (numbering according to the EU index numbering system).

[0726] The term "drug" is used herein to refer to a biopolymer, an extract made from biological material, a mixture of biopolymers, a chemical, a mixture of chemicals, or a mixture of chemicals and biopolymers. The term "therapeutic agent" refers to an agent that has biological activity.

[0727] "Polypeptide" or "protein" (used interchangeably herein) refer to a chain of amino acids of any length. The chain can be linear or branched. The chain can contain one or more modified amino acids. The term also encompasses amino acid chains that are natural or modified by intervention, e.g., disulfide bond formation, glycosylation, lipidation, acetylation, phosphorylation, or any other manipulation or modification, e.g., conjugation with a labeling component. For example, polypeptides containing one or more amino acid analogs (including, e.g., unnatural amino acids, etc.), and other modifications known in the art, are also included within this definition. It is understood that polypeptides can exist as single chains or associated chains.

[0728] As used herein, a "first polypeptide" is any polypeptide that associates with a second polypeptide. The first and second polypeptides meet at an interface. In addition to the interface, the first polypeptide may contain one or more additional domains, such as a "binding domain" (e.g., an antibody variable domain, receptor-binding domain, ligand-binding domain, or enzymatic domain), or an antibody constant domain (or portion thereof) including CH2, CH1, and CL domains. Typically, the first polypeptide contains at least one domain derived from an antibody. This domain is conveniently a constant domain, such as the CH3 domain of an antibody, and can form the interface of the first polypeptide. Exemplary first polypeptides include antibody heavy chain polypeptides, chimeras in which an antibody constant domain is combined with a binding domain of a heterologous polypeptide, receptor polypeptides, ligand polypeptides, and antibody variable domain polypeptides (e.g., bispecific antibodies).

[0729] In addition to the interface, the second polypeptide may contain additional domains such as a "binding domain" (e.g., an antibody variable domain, receptor-binding domain, ligand-binding domain, or enzymatic domain), or an antibody constant domain (or portion thereof) comprising the CH2, CH1, and CL domains. Typically, the second polypeptide contains at least one domain derived from an antibody. This domain is conveniently a constant region, such as the CH3 domain of an antibody, and can form the interface of the second polypeptide. Exemplary second polypeptides include antibody heavy chain polypeptides, chimeras in which an antibody constant domain is combined with a binding domain of a heterologous polypeptide, and antibody variable domain polypeptides (e.g., bispecific antibodies).

[0730] "Polynucleotide" or "nucleic acid" (used interchangeably herein) refers to a chain of nucleotides of any length, including DNA and RNA. Nucleotides can be deoxyribonucleotides, ribonucleotides, modified nucleotides or bases or their analogs, or any substance that can be incorporated into a chain by DNA or RNA polymerase. Polynucleotides can include modified nucleotides, such as methylated nucleotides and their analogs. If present, modifications to the nucleotide structure can be imparted before or after assembly of the chain. The sequence of nucleotides can be interrupted by non-nucleotide components. Polynucleotides can be further modified after polymerization, for example, by conjugation with a labeling component. Other types of modifications include, for example, "caps," substitutions with one or more analogs of naturally occurring nucleotides, internucleotide modifications such as those with uncharged linkages (e.g., methylphosphonates, phosphotriesters, phosphoamidates, carbamates, etc.) and charged linkages (e.g., phosphorothioates, phosphorodithioates, etc.), those containing pendant moieties such as proteins (e.g., nucleases, toxins, antibodies, signal peptides, poly-L-lysine, etc.), those with intercalators (e.g., acridine, psoralen, etc.), those containing chelators (e.g., metals, radioactive metals, boron, oxidizing metals, etc.), those containing alkylators, those with modified linkages (e.g., alpha-anomeric nucleic acids, etc.), and unmodified forms of polynucleotides. Additionally, any of the hydroxyl groups normally present on the sugar may be replaced, for example, by phosphonate groups, phosphate groups, protected by standard protecting groups, or activated to prepare additional linkages to additional nucleotides, or conjugated to a solid support. The 5' and 3' terminal OH can be phosphorylated or substituted with amines or organic capping group moieties of 1 to 20 carbon atoms. Other hydroxyls may also be derivatized to standard protecting groups.Polynucleotides can also contain analog forms of ribose or deoxyribose sugars commonly known in the art, including, for example, 2'-O-methyl-, 2'-O-allyl, 2'-fluoro-, or 2'-azido-ribose, carbocyclic sugar analogs, alpha- or beta-anomeric sugars, epimeric sugars such as arabinose, xylose, or lyxose, pyranose sugars, furanose sugars, sedoheptulose, acyclic analogs, and abasic nucleoside analogs such as methyl riboside.

[0731] As used herein, nucleic acids are written left to right in 5' to 3' orientation, and amino acid sequences are written left to right in amino to carboxy orientation, respectively. Practitioners are directed, inter alia, to Sambrook et al., 1989, and Ausubel FM et al., 1993, for definitions and terminology of the art. It should be understood that the invention is not limited to the particular methodology, protocols, and reagents described, as these may vary.

[0732] Polynucleotides complementary to any such sequences are also encompassed by the present invention.Polynucleotides can be single-stranded (coding or antisense) or double-stranded, and can be DNA (genomic, cDNA, or synthetic) or RNA molecules.RNA molecules include mature and non-mature mRNAs, such as precursor mRNAs (pre-mRNAs) or heterogeneous nuclear mRNAs (hnRNAs) and mature mRNAs.Additional coding or non-coding sequences can, but do not have to, be present in the polynucleotides of the present invention, and polynucleotides can, but do not have to, be linked to other molecules or supporting materials.

[0733] It will be recognized by those skilled in the art that, as a result of the degeneracy of the genetic code, many nucleotide sequences exist that encode the amino acid sequences provided herein. Polynucleotides that vary due to differences in codon usage are specifically contemplated by the present invention.

[0734] "Conservative substitution" refers to the replacement of one amino acid with a biologically, chemically, or structurally similar residue. Biologically similar means that the substitution does not destroy biological activity. Structurally similar means that the amino acid has a similar length or a similar size of the side chain, for example, alanine, glycine, and serine. Chemical similarity means that the residue has the same charge, or is both hydrophilic and hydrophobic. Specific examples include the replacement of one hydrophobic residue, such as isoleucine, valine, leucine, or methionine, with another, or the replacement of one polar residue with another, such as the replacement of arginine with lysine, the replacement of glutamic acid with aspartic acid, or the replacement of glutamine with asparagine, the replacement of serine with threonine, etc. Specific examples of conservative substitutions include the substitution of a hydrophobic residue such as isoleucine, valine, leucine, or methionine for another, or a polar residue for another, such as arginine for lysine, glutamic acid for aspartic acid, or glutamine for asparagine. Conservative amino acid substitutions typically include, for example, substitutions within the following groups: glycine, alanine, valine, isoleucine, and leucine; aspartic acid and glutamic acid; asparagine and glutamine; serine and threonine; lysine and arginine; and phenylalanine and tyrosine.

[0735] The present invention also encompasses modifications to the antibodies provided herein, including functionally equivalent antibodies that do not significantly affect their properties, and variants with enhanced or decreased activity or affinity. For example, the amino acid sequence may be mutated to obtain an antibody with the desired binding affinity for IL-4, IL-13, IL-33, TSLP, or p40. Examples of modified polypeptides include polypeptides with conservative substitutions of amino acid residues, deletions or additions of one or more amino acids that do not significantly adversely alter the functional activity or that mature (increase) the affinity of the polypeptide for its ligand, or the use of chemical analogs.

[0736] Amino acid sequence insertions include amino- or carboxyl-terminal fusions ranging in length from one residue to polypeptides containing 100 or more residues, as well as intrasequence insertions of single or multiple amino acid residues. Examples of terminal insertions include antibodies with an N-terminal methionyl residue or antibodies fused to an epitope tag. Other insertional variants of antibody molecules include the fusion to the N- or C-terminus of the antibody of an enzyme or polypeptide that increases the half-life of the antibody in the blood circulation.

[0737] Substitutional variants have at least one amino acid residue in the antibody molecule removed and a different residue inserted in its place. Sites of greatest interest for substitutional mutagenesis include hypervariable regions, although FR changes are also contemplated. Conservative substitutions are shown below as residues within the same numbering group (1-6). If such substitutions result in altered biological activity, more substantial changes, designated "exemplary substitutions," further described below in reference to amino acid classes, can be introduced and the products screened.

[0738] Substantial modification of the biological properties of the antibody is achieved by selecting substitutions that do not significantly differ in their effect on (a) the structure of the polypeptide backbone in the area of ​​the substitution, e.g., sheet or helix conformation, (b) the charge or hydrophobicity of the molecule at the target site, or (c) maintaining side chain bulk. Naturally occurring amino acid residues are divided into groups based on common side chain properties: (1) Nonpolar: Norleucine, Met, Ala, Val, Leu, Ile; (2) uncharged polar: Cys, Ser, Thr, Asn, Gln; (3) Acidic (negatively charged): Asp, Glu; (4) Basic (positively charged): Lys, Arg; (5) residues that influence chain orientation: Gly, Pro; and (6) Aromatic: Trp, Tyr, Phe, His.

[0739] Non-conservative substitutions are made by exchanging a member of one of these classes for another class.

[0740] Any cysteine ​​residue not involved in maintaining the proper conformation of the antibody may also be substituted, generally with serine, to improve the oxidative stab...
