BACKGROUND ART

[0002] Antibodies are drawing attention as pharmaceuticals since they are highly stable in blood and have few side effects (Non-patent Documents 1 and 2). Almost all antibody pharmaceuticals currently on the market are antibodies of the human IgG1 subclass. One of the known functions of IgG class antibodies is antibody-dependent cell-mediated cytotoxicity (hereinafter denoted as ADCC activity) (Non-patent Document 3). For an antibody to exhibit ADCC activity, the antibody Fc region must bind to an Fc.gamma. receptor (hereinafter denoted as Fc.gamma.R) which is an antibody-binding receptor present on the surface of effector cells such as killer cells, natural killer cells, and activated macrophages.

[0003] In humans, the Fc.gamma.RIa (CD64A), Fc.gamma.RIIa (CD32A), Fc.gamma.RIIb (CD32B), Fc.gamma.RIIIa (CD16A), and Fc.gamma.RIIIb (CD16B) isoforms have been reported as the Fc.gamma.R protein family, and the respective allotypes have also been reported (Non-patent Document 7). Fc.gamma.RIa, Fc.gamma.RIIa, and Fc.gamma.RIIIa are called activating Fc.gamma.R since they have immunologically active functions, and Fc.gamma.RIIb is called inhibitory Fc.gamma.R since it has immunosuppressive functions (Non-patent Document 8).

[0004] In the binding between the Fc region and Fc.gamma.R, several amino acid residues in the antibody hinge region and CH2 domain, and a sugar chain attached to Asn at position 297 (EU numbering) bound to the CH2 domain have been shown to be important (Non-patent Documents 4, 5, and 6). Various variants having Fc.gamma.R-binding properties, mainly antibodies with mutations introduced into these sites, have been studied so far; and Fc region variants having higher binding activities towards activating Fc.gamma.R have been obtained (Patent Documents 1, 2, 3, and 4).

[0005] When activating Fc.gamma.R is cross-linked with an immune complex, it phosphorylates immunoreceptor tyrosine-based activating motifs (ITAMs) contained in the intracellular domain or FcR common .gamma.-chain (an interaction partner), activates a signal transducer SYK, and triggers inflammatory immune response by initiating an activation signal cascade (Non-patent Document 9).

[0006] Fc.gamma.RIIb is the only Fc.gamma.R expressed on B cells (Non-patent Document 10). Interaction of the antibody Fc region with Fc.gamma.RIIb has been reported to suppress the primary immune response of B cells (Non-patent Document 11). Furthermore, it is reported that when Fc.gamma.RIIb on B cells and a B cell receptor (BCR) are cross-linked via an immune complex in blood, B cell activation is suppressed, and antibody production by B cells is suppressed (Non-patent Document 12). In this immunosuppressive signal transduction mediated by BCR and Fc.gamma.RIIb, the immunoreceptor tyrosine-based inhibitory motif (ITIM) contained in the intracellular domain of Fc.gamma.RIIb is necessary (Non-patent Documents 13 and 14). When ITIM is phosphorylated upon signaling, SH2-containing inositol polyphosphate 5-phosphatase (SHIP) is recruited, transduction of other activating Fc.gamma.R signal cascades is inhibited, and inflammatory immune response is suppressed (Non-patent Document 15). Furthermore, aggregation of Fc.gamma.RIIb alone has been reported to transiently suppress calcium influx due to BCR cross-linking and B cell proliferation in a BCR-independent manner without inducing apoptosis of IgM-producing B cells (Non-patent Document 16).

[0007] Furthermore, Fc.gamma.RIIb is also expressed on dendritic cells, macrophages, activated neutrophils, mast cells, and basophils. Fc.gamma.RIIb inhibits the functions of activating Fc.gamma.R such as phagocytosis and release of inflammatory cytokines in these cells, and suppresses inflammatory immune responses (Non-patent Document 8).

[0008] The importance of immunosuppressive functions of Fc.gamma.RIIb has been elucidated so far through studies using Fc.gamma.RIIb knockout mice. There are reports that in Fc.gamma.RIIb knockout mice, humoral immunity is not appropriately regulated (Non-Patent Document 17), sensitivity towards collagen-induced arthritis (CIA) is increased (Non-patent Document 18), lupus-like symptoms are presented, and Goodpasture's syndrome-like symptoms are presented (Non-patent Document 19).

[0009] Furthermore, regulatory inadequacy of Fc.gamma.RIIb has been reported to be related to human autoimmnue diseases. For example, the relationship between genetic polymorphism in the transmembrane region and promoter region of Fc.gamma.RIIb, and the frequency of development of systemic lupus erythematosus (SLE) (Non-patent Documents 20, 21, 22, 23, and 24), and decrease of Fc.gamma.RIIb expression on the surface of B cells in SLE patients (Non-patent Document 25 and 26) have been reported.

[0010] From mouse models and clinical findings as such, Fc.gamma.RIIb is considered to play the role of controlling autoimmune diseases and inflammatory diseases mainly through involvement with B cells, and it is a promising target molecule for controlling autoimmune diseases and inflammatory diseases.

[0011] IgG1, mainly used as a commercially available antibody pharmaceutical, is known to bind not only to Fc.gamma.RIIb, but also strongly to activating Fc.gamma.R (Non-patent Document 27). It may be possible to develop antibody pharmaceuticals having greater immunosuppressive properties compared with those of IgG1, by utilizing an Fc region with enhanced Fc.gamma.RIIb binding, or improved Fc.gamma.RIIb-binding selectivity compared with activating Fc.gamma.R. For example, it has been suggested that the use of an antibody having a variable region that binds to BCR and an Fc with enhanced Fc.gamma.RIIb binding may inhibit B cell activation (Non-patent Document 28). It has been reported that crosslinking Fc.gamma.RIIb on B cells and IgE bound to a B-cell receptor suppresses differentiation of B cells into plasma cells, which as a result causes suppression of IgE production; and in human PBMC-transplanted mice, human IgG and IgM concentrations are maintained whereas the human IgE concentration is decreased (Non-patent Document 29). Besides IgE, it has been reported that when Fc.gamma.RIIb and CD79b forming a B-cell receptor complex are cross-linked by an antibody, B cell proliferation is suppressed in vitro, and symptoms are alleviated in the collagen arthritis model (Non-patent Document 30).

[0012] Besides B cells, it has been reported that crosslinking of Fc.epsilon.RI and Fc.gamma.RIIb on mast cells using molecules, in which the Fc portion of an IgG with enhanced Fc.gamma.RIIb binding is fused to the Fc portion of IgE that binds to an IgE receptor Fc.epsilon.RI, causes Fc.gamma.RIIb phosphorylation of Fc.gamma.RIIb, thereby suppressing Fc.epsilon.RI-dependent calcium influx. This suggests that inhibition of degranulation via Fc.gamma.RIIb stimulation is possible by enhancing Fc.gamma.RIIb binding (Non-patent Document 31).

[0013] Accordingly, an antibody having an Fc with improved Fc.gamma.RIIb-binding activity is suggested to be promising as a therapeutic agent for inflammatory diseases such as autoimmune diseases.

[0014] Furthermore, mutants with enhanced Fc.gamma.RIIb binding have been suggested to be promising therapeutic agents for cancer, as well as therapeutic agents for inflammatory diseases such as autoimmune diseases. So far, Fc.gamma.RIIb has been found to play an important role in the agonistic activity of agonist antibodies against the anti-TNF receptor family. Specifically, it has been suggested that interaction with Fc.gamma.RIIb is required for the agonistic activity of antibodies against CD40, DR4, DR5, CD30, and CD137, which are included in the TNF receptor family (Non-patent Documents 32, 33, 34, 35, 36, and 37). Non-patent Document 32 shows that the use of antibodies with enhanced Fc.gamma.RIIb binding enhances the anti-tumor effect of anti-CD40 antibodies. Accordingly, antibodies with enhanced Fc.gamma.RIIb are expected to have an effect of enhancing agonistic activity of agonist antibodies including antibodies against the anti-TNF receptor family.

[0015] Antibodies having an Fc with improved Fc.gamma.RIIb-binding activity have been reported (Non-patent Document 28). In this Document, Fc.gamma.RIIb-binding activity was improved by adding alterations such as S267E/L328F, G236D/S267E, and S239D/S267E to an antibody Fc region. Among them, the antibody introduced with the S267E/L328F mutation most strongly binds to Fc.gamma.RIIb, and maintains the same level of binding to Fc.gamma.RIa and Fc.gamma.RIIa type H as that of a naturally-occurring IgG1. However, another report shows that this alteration enhances the binding to type-R Fc.gamma.RIIa several hundred times to the same level of Fc.gamma.RIIb binding, which means the Fc.gamma.RIIb-binding selectivity is not improved in comparison with type-R Fc.gamma.RIIa (Patent Document 5).

[0016] Even if Fc.gamma.RIIb binding had been enhanced compared with that of IgG1, only the effect of enhancing Fc.gamma.RIIa binding and not the enhancement of Fc.gamma.RIIb binding is considered to have influence on cells such as platelets which express Fc.gamma.RIIa but do not express Fc.gamma.RIIb (Non-patent Document 8). For example, the group of patients who were administered bevacizumab, an antibody against VEGF, is known to have an increased risk for thromboembolism (Non-patent Document 38). Furthermore, thromboembolism has been observed in a similar manner in clinical development tests of antibodies against the CD40 ligand, and the clinical study was discontinued (Non-patent Document 39). In both cases of these antibodies, later studies using animal models and such have suggested that the administered antibodies aggregate platelets via Fc.gamma.RIIa binding on the platelets, and form blood clots (Non-patent Documents 40 and 41). In systemic lupus erythematosus which is an autoimmune disease, platelets are activated via an Fc.gamma.RIIa-dependent mechanism, and platelet activation has been reported to correlate with the severity of symptoms (Non-patent Document 42). Even if Fc.gamma.RIIb binding is enhanced, administering an antibody with enhanced Fc.gamma.RIIa binding to such patients who already have a high risk for developing thromboembolism will increase the risk for developing thromboembolism, thus is extremely dangerous.

[0017] Furthermore, antibodies with enhanced Fc.gamma.RIIa binding have been reported to enhance macrophage-mediated antibody dependent cellular phagocytosis (ADCP) (Non-patent Document 43). When antibody's antigens are phagocytized by macrophages, antibodies themselves are also phagocytized at the same time. In that case, peptide fragments derived from those antibodies are also presented as an antigen and the antigenicity may become higher, thereby increasing the risk of production of antibodies against antibodies (anti-antibodies). More specifically, enhancing Fc.gamma.RIIa binding will increase the risk of production of antibodies against the antibodies, and this will remarkably decrease their value as pharmaceuticals.

[0018] More specifically, the value as pharmaceuticals will be considerably reduced when Fc.gamma.RIIa binding is enhanced, which leads to increased risk of thrombus formation via platelet aggregation, higher antigenicity, and increased risk of anti-antibody production.

[0019] From such a viewpoint, the aforementioned Fc with enhanced Fc.gamma.RIIb binding shows remarkably enhanced type-R Fc.gamma.RIIa binding compared with that of a naturally-occurring IgG1. Therefore, its value as a pharmaceutical for patients carrying type-R Fc.gamma.RIIa is considerably reduced. Types H and R of Fc.gamma.RIIa are observed in Caucasians and African-Americans with approximately the same frequency (Non-patent Documents 44 and 45). Therefore, when this Fc was used for treatment of autoimmune diseases, the number of patients who can safely use it while enjoying its effects as a pharmaceutical will be limited.

[0020] Furthermore, in dendritic cells deficient in Fc.gamma.RIIb or dendritic cells in which the interaction between Fc.gamma.RIIb and the antibody Fc portion is inhibited by an anti-Fc.gamma.RIIb antibody, dendritic cells have been reported to mature spontaneously (Non-patent Documents 46 and 47). This report suggests that Fc.gamma.RIIb is actively suppressing maturation of dendritic cells in a steady state where inflammation and such are not taking place. Fc.gamma.RIIa is expressed on the dendritic cell surface in addition to Fc.gamma.RIIb; therefore, even if binding to inhibitory Fc.gamma.RIIb is enhanced and if binding to activating Fc.gamma.R such as Fc.gamma.RIIa is also enhanced, maturation of dendritic cells may be promoted as a result. More specifically, improving not only the Fc.gamma.RIIb-binding activity but also the ratio of Fc.gamma.RIIb-binding activity relative to Fc.gamma.RIIa-binding activity is considered to be important in providing antibodies with an immunosuppressive action.

[0021] Therefore, when considering generation of pharmaceuticals that utilize the Fc.gamma.RIIb binding-mediated immunosuppressive action, there is a need for an Fc that not only has enhanced Fc.gamma.RIIb-binding activity, but also has binding to both Fc.gamma.RIIa, types H and R allotypes, which is maintained at a similar level or is weakened to a lower level than that of a naturally-occurring IgG1.

[0022] Meanwhile, cases where amino acid alterations were introduced into the Fc region to increase the Fc.gamma.RIIb-binding selectivity have been reported so far (Non-patent Document 48). However, all variants said to have improved Fc.gamma.RIIb selectivity as reported in this document showed decreased Fc.gamma.RIIb binding compared with that of a naturally-occurring IgG1. Therefore, it is considered to be difficult for these variants to actually induce an Fc.gamma.RIIb-mediated immunosuppressive reaction more strongly than IgG1.

[0023] Furthermore, since Fc.gamma.RIIb plays an important role in the agonist antibodies mentioned above, enhancing their binding activity is expected to enhance the agonistic activity. However, when Fc.gamma.RIIa binding is similarly enhanced, unintended activities such as ADCC activity and ADCP activity will be exhibited, and this may cause side effects. Also from such viewpoint, it is preferable to be able to selectively enhance Fc.gamma.RIIb-binding activity.

[0024] From these results, in producing antibody pharmaceuticals to be used for treating autoimmune diseases and cancer utilizing Fc.gamma.RIIb, it is important that compared with those of a naturally-occurring IgG, the activities of binding to both Fc.gamma.RIIa allotypes are maintained or decreased, and Fc.gamma.RIIb binding is enhanced. However, Fc.gamma.RIIb shares 93% sequence identity in the extracellular region with that of Fc.gamma.RIIa which is one of the activating Fc.gamma.Rs, and they are very similar structurally. There are allotypes of Fc.gamma.RIIa, H type and R type, in which the amino acid at position 131 is His (type H) or Arg (type R), and yet each of them reacts differently with the antibodies (Non-patent Document 49). Therefore, to produce an Fc region that selectively binds to Fc.gamma.RIIb, the most difficult problem may be conferring to the antibody Fc region with the property of selectively improved Fc.gamma.RIIb-binding activity, which involves distinguishing these homologous sequences, and decreasing or not increasing the binding activity towards each allotype of Fc.gamma.RIIa, while increasing the binding activity towards Fc.gamma.RIIb. So far, variants having sufficient Fc.gamma.RIIb selectivity have not been obtained. Patent Document 5 reports variants with enhanced Fc.gamma.RIIb-binding activity; however, the degree of enhancement is low, and there is a demand for development of variants having properties similar to those described above.

As a result, the present inventors discovered that a polypeptide comprising an antibody Fc region that comprises an alteration produced by substituting Pro at position 238 (EU numbering) with Asp or Leu at position 328 (EU numbering) with Glu enhances Fc.gamma.RIIb-binding activity, and decreases Fc region-mediated binding activity towards both allotypes of Fc.gamma.RIIa, types H and R. Furthermore, the present inventors discovered that a polypeptide comprising an antibody Fc region that comprises an alteration of substituting Pro at position 238 (EU numbering) with Asp and several other alterations that enhance Fc.gamma.RIIb-binding activity, and maintains or decreases Fc region-mediated binding activities towards both allotypes of Fc.gamma.RIIa, types H and R.

Effects of the Invention

[0083] Polypeptides comprising an Fc region having maintained or decreased binding activities towards both allotypes of Fc.gamma.RIIa, types R and H, and having enhanced Fc.gamma.RIIb-binding activity in comparison with a parent polypeptide are provided by the present invention. By using the polypeptides with enhanced binding selectivity for Fc.gamma.RIIb than for both allotypes of Fc.gamma.RIIa (types H and R), it is possible to transmit inhibitory signals of inflammatory immune response mediated by phosphorylation of ITIM of Fc.gamma.RIIb in patients carrying either of the allotypes, type R and type H. Furthermore, by conferring an antibody Fc with the property of selective Fc.gamma.RIIb binding, it may be possible to suppress anti-antibody production through the Fc.gamma.RIIb-mediated immunosuppressive action.

MODE FOR CARRYING OUT THE INVENTION

[0100] The present invention provides polypeptides comprising an IgG Fc region that have maintained or decreased Fc.gamma.RIIa-binding, and having enhanced Fc.gamma.RIIb-binding activity in comparison with a parent polypeptide by introducing amino acid substitution(s) into the IgG Fc region.

[0101] More specifically, the present invention provides a polypeptide comprising an antibody Fc region that comprises a substitution of Pro at position 238 (EU numbering) with Asp or substitution of Leu at position 328 (EU numbering) with Glu, and a polypeptide comprising an antibody Fc region that comprises combination of a substitution of Pro at position 238 (EU numbering) with Asp and several specific amino acid substitutions. Furthermore, the present invention provides a method for maintaining or decreasing binding activity towards both allotypes of Fc.gamma.RIIa and enhancing the Fc.gamma.RIIb-binding activity in comparison with a parent polypeptide. The present invention also provides a method for suppressing the antibody production in comparison with a parent polypeptide when the polypeptide is administered in vivo.

[0102] "Polypeptides of the present invention" generally refers to peptides or proteins approximately ten amino acids or more in length. Furthermore, they are generally polypeptides derived from organisms, but are not particularly limited, and for example, they may be polypeptides comprising an artificially designed sequence. Furthermore, they may be any of naturally-occurring polypeptides, synthetic polypeptides, recombinant polypeptides, or such.

[0103] "Fc.gamma. receptors" (herein, referred to as Fc.gamma. receptors or Fc.gamma.R) refers to receptors that may bind to the Fc region of IgG1, IgG2, IgG3, and IgG4 monoclonal antibodies, and practically means any member of the family of proteins encoded by the Fc.gamma. receptor genes. In humans, this family includes Fc.gamma.RI (CD64) including isoforms Fc.gamma.RIa, Fc.gamma.RIb, and Fc.gamma.RIc; Fc.gamma.RII (CD32) including isoforms Fc.gamma.RIIa (including allotypes H131 (type H) and R131 (type R)), Fc.gamma.RIIb (including Fc.gamma.RIIb-1 and Fc.gamma.RIIb-2), and Fc.gamma.RIIc; and Fc.gamma.RIII (CD16) including isoforms Fc.gamma.RIIIa (including allotypes V158 and F158), and Fc.gamma.RIIIb (including allotypes Fc.gamma.RIIIb-NA1 and Fc.gamma.RIIIb-NA2), and any human Fc.gamma.Rs, Fc.gamma.R isoforms or allotypes yet to be discovered, but is not limited thereto. The Fc.gamma.R includes human, mouse, rat, rabbit, and monkey-derived Fc.gamma.Rs but is not limited thereto, and may be derived from any organism. Mouse Fc.gamma.Rs include Fc.gamma.RI (CD64), Fc.gamma.RII (CD32), Fc.gamma.RIII (CD16), and Fc.gamma.RIII-2 (CD16-2), and any mouse Fc.gamma.Rs, or Fc.gamma.R isoforms or allotypes yet to be discovered, but are not limited thereto. Favorable examples of such Fc.gamma. receptors include human Fc.gamma.RI (CD64), Fc.gamma.RIIA (CD32), Fc.gamma.RIIB (CD32), Fc.gamma.RIIIA (CD16), and/or Fc.gamma.RIIIB (CD16).

[0104] The polynucleotide sequence and amino acid sequence of Fc.gamma.RI are set forth in SEQ ID NOs: 1 (NM.sub.--000566.3) and 2 (NP.sub.--000557.1), respectively;

the polynucleotide sequence and amino acid sequence of Fc.gamma.RIIA are set forth in SEQ ID NOs: 3 (BCO20823.1) and 4 (AAH20823.1), respectively; the polynucleotide sequence and amino acid sequence of Fc.gamma.RIIB are set forth in SEQ ID NOs: 5 (BC146678.1) and 6 (AAI46679.1), respectively; the polynucleotide sequence and amino acid sequence of Fc.gamma.RIIIA are set forth in SEQ ID NOs: 7 (BCO33678.1) and 8 (AAH33678.1), respectively; and the polynucleotide sequence and amino acid sequence of Fc.gamma.RIIIB are set forth in SEQ ID NOs 9 (BC128562.1) and 10 (AAI28563.1), respectively (the RefSeq Registration number is indicated inside the parentheses).

[0105] In Fc.gamma.RIIa, there are two allotypes, one where the amino acid at position 131 of Fc.gamma.RIIa is histidine (type H) and the other where this amino acid is substituted with arginine (type R) (J. Exp. Med, 172: 19-25, 1990).

[0106] Herein, "parent polypeptide" refers to a polypeptide that will serve as the basis for the production of polypeptides comprising an antibody Fc region of the present invention. More specifically, it is a polypeptide comprising an antibody Fc region and is the polypeptide prior to alteration of at least one amino acid in the Fc region. The parent polypeptide in the present invention may be, for example, a polypeptide comprising the Fc region of a naturally-occurring IgG, or it may be a polypeptide comprising an Fc region of an IgG to which an alteration other than the amino acid alterations of the present invention has been made to a naturally-occurring IgG.

[0107] "Naturally-occurring IgGs" refers to polypeptides belonging to a class of antibodies practically encoded by immunoglobulin gamma genes and comprising an amino acid sequence identical to those of IgGs found in nature. For example, a naturally-occurring human IgG means a naturally-occurring human IgG1, naturally-occurring human IgG2, naturally-occurring human IgG3, naturally-occurring human IgG4, or such. Naturally-occurring IgGs also include mutants spontaneously produced from them.

[0108] The Fc region of a naturally-occurring IgG means an Fc region comprising an amino acid sequence identical to that of the Fc region derived from an IgG found in nature. The Fc region of a naturally-occurring IgG is shown in FIG. 5 (SEQ ID NOs: 11-14), and for example, it refers to Fc regions derived from naturally-occurring human IgG1, Fc regions derived from naturally-occurring human IgG2, Fc regions derived from naturally-occurring human IgG3, and Fc regions derived from naturally-occurring human IgG4. The Fc regions of naturally-occurring IgGs also include mutants spontaneously produced from them.

[0109] In the present invention, whether or not the binding activity towards each type of Fc.gamma.R is enhanced, or maintained or decreased in a polypeptide or an Fc region of the present invention can be determined, for example, by observing whether there is a decrease or an increase in the dissociation constant (KD) value obtained from the results of sensorgram analysis, where various Fc.gamma.Rs are subjected to interaction as an analyte with antibodies immobilized onto the sensor chips or captured onto the sensor chips using Protein A, Protein L, Protein A/G, Protein G, anti-lamda chain antibodies, anti-kappa chain antibodies, antigenic peptides, antigenic proteins, or such using BIACORE which is an interaction analyzer that utilizes the surface plasmon resonance (SPR) phenomena, as shown in the Examples. Alternatively, it can also be determined by observing whether there is an increase or a decrease in the value obtained by dividing the amount of change in the resonance unit (RU) value on the sensorgram before and after various types of Fc.gamma.Rs are subjected to interaction as an analyte with antibodies immobilized onto the sensor chips or captured onto the sensor chips using Protein A, Protein L, Protein A/G, Protein G, anti-lamda chain antibodies, anti-kappa chain antibodies, antigenic peptides, antigenic proteins, or such, by the amount of change of resonance units (RU) before and after antibodies are immobilized or captured onto the sensor chip. Furthermore, it can be determined by observing an increase or a decrease in the dissociation constant (KD) values obtained from sensorgram analysis, where a sample such as an antibody to be evaluated is subjected to interaction as an analyte using a sensor chip onto which Fc.gamma.R is immobilized directly or via an anti-tag antibody. Alternatively, it can be determined by observing whether the amount of change in sensorgram values increases or decreases before and after a sample such as an antibody to be evaluated is subjected to interaction as an analyte with the sensor chip onto which Fc.gamma.R is immobilized directly or via an anti-tag antibody.

[0110] Specifically, the binding activity of an Fc region towards an Fc.gamma. receptor can be measured by the Amplified Luminescent Proximity Homogeneous Assay (ALPHA) screening, the BIACORE method which utilizes the surface plasmon resonance (SPR) phenomena, or such, in addition to ELISA or fluorescence activated cell sorting (FACS) (Proc. Natl. Acad. Sci. USA (2006) 103 (11): 4005-4010).

[0111] ALPHA screening is performed by ALPHA technology which uses two beads, a donor and an acceptor, based on the following principles. Luminescent signals are detected only when molecules bound to donor beads physically interact with molecules bound to the acceptor beads, and the two beads are in close proximity to each other. Laser-excited photosensitizer in the donor beads converts ambient oxygen to excited-state singlet oxygen. Singlet oxygen is dispersed around the donor beads, and when it reaches the adjacent acceptor beads, chemiluminescent reaction is induced in the beads, and light is ultimately emitted. When the molecules bound to the donor beads do not interact with the molecules bound to the acceptor beads, the chemiluminescent reaction does not take place because singlet oxygen produced by the donor beads does not reach the acceptor beads.

[0112] For example, a biotinylated polypeptide complex is bound to the donor beads, and Fc.gamma. receptor tagged with glutathione S transferase (GST) is linked to the acceptor beads. In the absence of a competing polypeptide complex comprising a mutant Fc region, the polypeptide complex comprising a wild-type Fc region interacts with the Fc.gamma. receptor and produces 520-620 nm signals. The polypeptide complex comprising an untagged mutant Fc region competes with the polypeptide complex comprising a wild-type Fc region for interaction with the Fc.gamma. receptor. Relative binding activities can be determined by quantifying the decrease in fluorescence observed as a result of the competition. Biotinylation of polypeptide complexes such as antibodies using Sulfo-NHS-biotin and such is well known. The method of expressing the Fc.gamma. receptor and GST in a cell carrying a fusion gene produced by fusing a polynucleotide encoding the Fc.gamma. receptor in frame with a polynucleotide encoding GST in an expressible vector, and performing purification using a glutathione column is appropriately adopted as a method for tagging an Fc.gamma. receptor with GST. The obtained signals are preferably analyzed, for example, by fitting them to a one-site competition model which uses a non-linear regression analysis using software such as GRAPHPAD PRISM (GraphPad, San Diego).

[0113] One of the substances (the ligand) in observation of an interaction is immobilized onto a gold thin film on a sensor chip, and by shining light from the reverse side of the sensor chip so that total reflection takes place at the interface between the gold thin film and glass, a portion of reduced reflection intensity is formed in part of the reflected light (SPR signal). When the other one of the substances (the analyte) in observation of an interaction is made to flow on the sensor chip surface and the ligand binds to the analyte, the mass of the immobilized ligand molecule increases and the refractive index of the solvent on the sensor chip surface changes. The position of the SPR signal shifts as a result of this change in refractive index (on the other hand, the signal position returns when this binding dissociates). The Biacore system indicates the amount of shift mentioned above, or more specifically the time variable of mass by plotting the change in mass on the sensor chip surface on the ordinate as the measurement data (sensorgram). The amount of analyte bound to the ligand trapped on the sensor chip surface is determined from the sensorgram. Kinetic parameters such as association rate constants (ka) and dissociation rate constants (kd) are determined from the curves of the sensorgram, and the dissociation constants (KD) are determined from the ratio of these constants. In the BIACORE method, a method for measuring inhibition is preferably used. An example of the method for measuring inhibition is described in Proc. Natl. Acad. Sci. USA (2006) 103 (11): 4005-4010.

[0114] A polypeptide with decreased Fc.gamma.R-binding activity refers to a polypeptide that binds to Fc.gamma.R with a substantially lower binding activity than the parent polypeptide when assay is performed by keeping the amount of the parent polypeptide and the amount of the polypeptide comprising at least one amino acid alteration in the Fc region of the parent polypeptide (also called a polypeptide variant) practically the same.

[0115] For example, in the KD values measured by the above-mentioned measurement method, the KD value ratio (KD value of a polypeptide variant/KD value of a parent polypeptide) is preferably 1.25 or more, 2 or more, or 3 or more, and more preferably, 5 or more, 10 or more, 100 or more, 1,000 or more, or 10,000 or more.

[0116] Furthermore, in the KD values measured by the above-mentioned measurement method, the KD value is preferably increased by 1 .mu.M or more, and more preferably increased by 2 .mu.M or more, 3 .mu.M or more, 5 .mu.M or more, 10 .mu.M or more, 20 .mu.M or more, 50 .mu.M or more, and 100 .mu.M or more. Furthermore, in the KD values measured by the above-mentioned measurement method, the KD value is preferably 0.0001 .mu.M or more, and more preferably 0.001 .mu.M or more, 0.01 .mu.M or more, 0.1 .mu.M or more, 0.5 .mu.M or more, 1 .mu.M or more, 2 .mu.M or more, 3 .mu.M or more, 5 .mu.M or more, 10 .mu.M or more, 100 .mu.M or more, or 1,000 .mu.M or more.

[0117] A polypeptide with enhanced Fc.gamma.R-binding activity refers to a polypeptide that binds to Fc.gamma.R with a substantially higher binding activity than the parent polypeptide when assay is performed by keeping the amount of the parent polypeptide and the amount of the polypeptide variant practically the same.

[0118] For example, in the KD values measured by the above-mentioned measurement method, the KD value ratio (KD value of a parent polypeptide/KD value of a polypeptide variant) is preferably 1.25 or more, 2 or more, or 3 or more, and more preferably, 5 or more, 10 or more, 100 or more, 1,000 or more, or 10,000 or more.

[0119] Furthermore, in the KD values measured by the above-mentioned measurement method, the KD value is preferably decreased by 0.001 .mu.M or more, and more preferably decreased by 0.01 .mu.M, 0.1 .mu.M, 1 .mu.M or more, 2 .mu.M or more, 3 .mu.M or more, 5 .mu.M or more, 10 .mu.M or more, 20 .mu.M or more, 50 .mu.M or more, and 100 .mu.M or more.

[0120] Furthermore, in the KD values measured by the above-mentioned measurement method, the KD value is preferably 5 .mu.M or less, and more preferably 3 .mu.M or less, 1 .mu.M or less, 0.5 .mu.M or less, 0.1 .mu.M or less, 0.01 .mu.M or less, 0.001 .mu.M or less, or 0.0001 .mu.M or less.

[0121] A polypeptide with unchanged (maintained) Fc.gamma.R-binding activity refers to a polypeptide that binds to Fc.gamma.R with a binding activity practically unchanged from or equivalent to the parent polypeptide when assay is performed by keeping the amount of the parent polypeptide and the amount of the polypeptide comprising at least one amino acid alteration in the Fc region of the parent polypeptide (also called a polypeptide variant) practically the same.

[0122] Whether or not a polypeptide is a polypeptide having maintained or decreased Fc.gamma.RIIa-binding activity and having enhanced Fc.gamma.RIIb-binding activity can be determined using the KD value of this polypeptide for Fc.gamma.RIIa and the KD value of this polypeptide for Fc.gamma.RIIb determined according to the above-mentioned examples. An example is the case where the KD value of the polypeptide of the present invention for Fc.gamma.RIIb is decreased compared with the KD value of the parent polypeptide for Fc.gamma.RIIb; and the KD value of the polypeptide of the present invention for Fc.gamma.RIIa (type R and type H) is increased or maintained compared with the KD value of the parent polypeptide for Fc.gamma.RIIa (type R and type H). Furthermore, it is possible to determine by appropriately combining the KD value of the polypeptide for Fc.gamma.RIa and the KD value of the polypeptide for Fc.gamma.RIIIa, which were determined according to the above-mentioned example.

[0123] In the present invention, an increased Fc.gamma.RIIb-binding activity means that, for example, in the KD values measured by the measurement method described above, the KD ratio of [KD value of the parent polypeptide]/[KD value of the polypeptide variant] is preferably 1.6 or more, 2 or more, or 3 or more, and more preferably 5 or more, 10 or more, 20 or more, 30 or more, and 50 or more.

[0124] Maintained or decreased binding activities towards Fc.gamma.RIIa (type R) and Fc.gamma.RIIa (type H) means that, for example, in the KD values measured by the measurement method described above, the KD ratio of [KD value for the stronger of the binding activities of a polypeptide variant towards Fc.gamma.RIIa (type R) and Fc.gamma.RIIa (type H)]/[KD value for the stronger of the binding activities of a parent polypeptide towards Fc.gamma.RIIa (type R) and Fc.gamma.RIIa (type H)] is preferably 0.7 or more, 1 or more, 2 or more, or 3 or more, and more preferably 5 or more, 10 or more, 20 or more, 30 or more, and 50 or more.

[0125] Polypeptides of the present invention preferably have maintained or decreased binding activities towards Fc.gamma.RIIa type R and Fc.gamma.RIIa type H. Furthermore, they preferably have maintained or decreased binding activities towards Fc.gamma.RIIa type R and Fc.gamma.RIIa type H, as well as a maintained or decreased Fc.gamma.RIIIa-binding activity. In addition, they preferably have a maintained or decreased binding activity towards Fc.gamma.RIa.

[0126] A maintained or decreased binding activity towards Fc.gamma.RIIIa or Fc.gamma.RIa means that, for example, in the KD values measured by the measurement method described above, the KD ratio of [KD value of the polypeptide variant]/[KD value of the parent polypeptide] is preferably 1 or more, 2 or more, or 3 or more, and more preferably 5 or more, 10 or more, 20 or more, 30 or more, and 50 or more.

[0127] Furthermore, whether or not a polypeptide of the present invention is a polypeptide with improved binding selectivity for Fc.gamma.RIIb rather than for Fc.gamma.RIIa can be determined by comparing the ratio of the KD value for Fc.gamma.RIIa to the KD value for Fc.gamma.RIIb of the polypeptide of the present invention (KD value for Fc.gamma.RIIa/KD value for Fc.gamma.RIIb) with the ratio of the KD value for Fc.gamma.RIIa to the KD value for Fc.gamma.RIIb of the parent peptide (KD value for Fc.gamma.RIIa/KD value for Fc.gamma.RIIb), which were determined according to the above-mentioned examples. Specifically, when the value of the KD ratio for the polypeptide of the present invention is greater than that of the parent polypeptide, the polypeptide of the present invention can be determined to have an improved binding selectivity for Fc.gamma.RIIb rather than for Fc.gamma.RIIa in comparison with the parent polypeptide.

[0128] The binding selectivity between Fc.gamma.RIIa (type R) and Fc.gamma.RIIb is, for example, a KD value ratio [KD value of the polypeptide variant for Fc.gamma.RIIa (type R)]/[KD value of the polypeptide variant for Fc.gamma.RIIb] of preferably 1.2 or more, 2 or more, or 3 or more for the KD values measured by the measurement method described above, and more preferably 5 or more, 10 or more, 20 or more, or 30 or more.

[0129] The binding selectivity between Fc.gamma.RIIa (type H) and Fc.gamma.RIIb is, for example, a KD value ratio [KD value of the polypeptide variant for Fc.gamma.RIIa (type H)]/[KD value of the polypeptide variant for Fc.gamma.RIIb] of preferably 4.2 or more, 5 or more, or 10 or more for the KD values measured by the measurement method described above, and more preferably 20 or more, 30 or more, 50 or more, 100 or more, or 200 or more.

[0130] Furthermore, whether or not the binding activities of the polypeptides of the present invention towards various Fc.gamma.Rs were maintained, enhanced, or decreased can be determined from the increase or decrease in the amount of binding of the various Fc.gamma.Rs to the polypeptides of the present invention, which were determined according to the examples described above. Here, the amount of binding of the various Fc.gamma.Rs to the polypeptides refers to values obtained by determining the difference in the RU values of sensorgrams that changed before and after interaction of various Fc.gamma.Rs as the analyte with each polypeptide, and dividing them by differences in the RU values of sensorgrams that changed before and after capturing polypeptides to the sensor chips.

[0131] Whether or not the polypeptides of the present invention is a polypeptide having maintained or decreased binding activities towards Fc.gamma.RIIa (type R and type H), and having increased binding activity towards Fc.gamma.RIIb can be determined by using the amount of Fc.gamma.RIIa binding of the polypeptide and the amount of Fc.gamma.RIIb binding of the polypeptide, which were determined according to the examples described above.

[0132] An example is the case where the amount of Fc.gamma.RIIb binding of a polypeptide of the present invention is increased compared with the amount of Fc.gamma.RIIb binding of a parent polypeptide, and the amount of Fc.gamma.RIIa (type R and type H) binding of a polypeptide of the present invention is equivalent to (maintained at) or preferably decreased from the amount of binding of a parent polypeptide towards Fc.gamma.RIIa (type R and type H). Furthermore, it is possible to determine by appropriately combining the amount of Fc.gamma.RIa binding and the amount of Fc.gamma.RIIIa binding of the polypeptide determined according to the examples described above.

[0133] "Fc region" refers to the region comprising a fragment consisting of a hinge portion or a part thereof, CH2 domain, or CH3 domain in an antibody molecule. According to EU numbering (herein, also called the EU INDEX) (see FIG. 5), an IgG-class Fc region refers to, for example, the region from cysteine at position 226 to the C terminus, or from proline at position 230 to the C terminus, but is not limited thereto.

[0134] The Fc region may be obtained preferably by re-eluting the fraction adsorbed onto protein A column after partially digesting IgG1, IgG2, IgG3, IgG4 monoclonal antibodies or such using a protease such as pepsin. The protease is not particularly limited as long as it can digest a full-length antibody so that Fab and F(ab')2 will be produced in a restrictive manner by appropriately setting the enzyme reaction conditions such as pH, and examples include pepsin and papain.

[0135] The present invention provides an antibody constant region comprising an Fc region which comprises an alteration produced by substituting Pro at position 238 (EU numbering) with Asp or substituting Leu at position 328 (EU numbering) with Glu in human IgG (IgG1, IgG2, IgG3, and IgG4). Polypeptides with maintained or decreased binding activities towards Fc.gamma.RIa, Fc.gamma.RIIIa, and both allotypes of Fc.gamma.RIIa, types R and H, as well as enhanced Fc.gamma.RIIb-binding activity in comparison with a parent polypeptide can be provided by introducing alteration of substituting Pro at position 238 (EU numbering) with Asp or substituting Leu at position 328 (EU numbering) with Glu in human IgG.

[0136] In the present invention, at least one alteration can be further added to the human IgG Fc region comprising the alteration produced by substituting Pro at position 238 (EU numbering) with Asp or substituting Leu at position 328 (EU numbering) with Glu. Here, alteration refers to any one of, or a combination of substitutions, deletions, additions, and insertions. Additional alterations can be further included with these alterations. The additional alteration can be selected from any one of, or combinations of amino acid substitutions, deletions, or modifications. For example, alterations that enhance the binding activity to Fc.gamma.RIIb, as well as maintain or decrease binding activities towards Fc.gamma.RIIa (type H) and Fc.gamma.RIIa (type R) can be added. Adding such alterations improves the binding selectivity for Fc.gamma.RIIb rather than for Fc.gamma.RIIa.

[0137] Among them, alterations that improve the binding selectivity for Fc.gamma.RIIb rather than for Fc.gamma.RIIa (type R) are preferred, and alterations that improve the binding selectivity for Fc.gamma.RIIb rather than for Fc.gamma.RIIa (type H) are more preferred.

[0140] Furthermore, for example, amino acid substitutions that improve FcRn-binding activity (J. Immunol. 2006 Jan. 1; 176(1): 346-56; J Biol. Chem. 2006 Aug. 18; 281(33): 23514-24; Int. Immunol. 2006 December; 18(12): 1759-69; Nat. Biotechnol. 2010 February; 28(2): 157-9.; WO 2006/019447; WO 2006/053301; and WO 2009/086320), and amino acid substitutions for improving antibody heterogeneity or stability (WO 2009/041613) may be introduced into an antibody constant region portion. Alternatively, polypeptides produced by conferring polypeptides of the present invention with the property of promoting disappearance of antigens, which are described in WO 2011/122011 or PCT/JP2011/072550, and polypeptides conferring the property for repeated binding to a plurality of antigen molecules, which are described in WO 2009/125825 or PCT/JP2011/077619, are also included in the present invention.

[0141] Preferred examples of polypeptides of the present invention include IgG antibodies. When an IgG antibody is used as the antibody, the type of constant region is not limited, and an IgG isotypes (subclasses) such as IgG1, IgG2, IgG3, and IgG4 can be used. IgG antibodies of the present invention are preferably human IgG, and more preferably human IgG1 and human IgG4. The amino acid sequences of the heavy-chain constant regions of human IgG1 and human IgG4 are known. A plurality of allotype sequences due to genetic polymorphisms have been described in Sequences of Proteins of Immunological Interest, NIH Publication No. 91-3242 for the human IgG1 constant region, and any of the sequences may be used in the present invention.

<Substitution>

[0142] When substituting amino acid residues, substitution to a different amino acid residue is carried out with the objective of altering aspects such as (a)-(c) described below:

(a) polypeptide backbone structure in the sheet-structure or helical-structure region; (b) electric charge or hydrophobicity at the target site; or (c) size of the side chain.

[0143] Amino acid residues are classified into the following groups based on their general side chain properties:

(1) hydrophobic: norleucine, met, ala, val, leu, and ile; (2) neutral hydrophilic: cys, ser, thr, asn, and gln; (3) acidic: asp and glu; (4) basic: his, lys, and arg; (5) residues that affect the chain orientation: gly and pro; and (6) aromatic: tip, tyr, and phe.

[0144] Substitution between amino acid residues within each of these amino acid groups is referred to as conservative substitution, and amino acid residue substitution between different groups is referred to as non-conservative substitution. Substitutions in the present invention may be conservative substitutions or non-conservative substitutions, or a combination of conservative substitutions and non-conservative substitutions.

[0145] Amino acid sequence alterations are produced by various methods known to those skilled in the art. Such methods include the site-directed mutagenesis method (Hashimoto-Gotoh, T, Mizuno, T, Ogasahara, Y, and Nakagawa, M. (1995) An oligodeoxyribonucleotide-directed dual amber method for site-directed mutagenesis. Gene 152: 271-275; Zoller, M J, and Smith, M. (1983) Oligonucleotide-directed mutagenesis of DNA fragments cloned into M13 vectors. Methods Enzymol. 100: 468-500; Kramer, W, Drutsa, V, Jansen, H W, Kramer, B, Pflugfelder, M, and Fritz, H J (1984) The gapped duplex DNA approach to oligonucleotide-directed mutation construction. Nucleic Acids Res. 12: 9441-9456; Kramer W, and Fritz H J (1987) Oligonucleotide-directed construction of mutations via gapped duplex DNA Methods. Enzymol. 154, 350-367; and Kunkel, TA (1985) Rapid and efficient site-specific mutagenesis without phenotypic selection. Proc Natl Acad Sci USA. 82: 488-492), the PCR mutation method, and the cassette mutation method, but are not limited thereto.

[0146] Amino acid modification of the present invention includes post-translational modification. A specific post-translational modification may be addition or deletion of a sugar chain. For example, in the IgG1 constant region consisting of the amino acid sequence of SEQ ID NO: 11, the amino acid residue at position 297 (EU numbering) may be sugar chain-modified. The sugar-chain structure for the modification is not limited. Generally, antibodies expressed in eukaryotic cells comprise glycosylation in the constant region. Therefore, antibodies expressed in cells such as those below are normally modified by some type of sugar chain: [0147] antibody-producing cells of mammals [0148] eukaryotic cells transformed with an expression vector comprising a DNA encoding an antibody

[0149] Eukaryotic cells shown here include yeast and animal cells. For example, CHO cells and HEK293H cells are representative animal cells used in transformation with an expression vector comprising an antibody-encoding DNA. On the other hand, those without glycosylation at this site are also included in the constant region of the present invention. Antibodies whose constant region is not glycosylated can be obtained by expressing an antibody-encoding gene in prokaryotic cells such as Escherichia coli.

[0150] Specifically, for example, sialic acid may be added to the sugar chain of an Fc region (MAbs. 2010 September-October; 2(5): 519-27).

<Antibody>

[0151] Furthermore, the present invention provides antibodies comprising an Fc region in which any of the above-mentioned amino acid sequences is altered.

[0152] The term "antibody/antibodies" in the present invention is used in the broadest sense, and as long as the desired biological activity is shown, it comprises any antibody such as monoclonal antibodies (including full-length monoclonal antibodies), polyclonal antibodies, antibody variants, antibody fragments, polyspecific antibodies (multi-specific antibodies) (for example, bispecific antibodies (diabodies)), chimeric antibodies, and humanized antibodies.

[0153] Regarding the antibodies of the present invention, the antigen type and antibody origin are not limited, and they may be any type of antibodies. The origin of the antibodies is not particularly limited, but examples include human antibodies, mouse antibodies, rat antibodies, and rabbit antibodies.

[0154] Methods for producing the antibodies are well known to those skilled in the art, and for example, monoclonal antibodies may be produced by the hybridoma method (Kohler and Milstein, Nature 256: 495 (1975)), or the recombination method (U.S. Pat. No. 4,816,567). Alternatively, they may be isolated from a phage antibody library (Clackson et al., Nature 352: 624-628 (1991); Marks et al., J. Mol. Biol. 222: 581-597 (1991)).

[0155] A humanized antibody is also called a reshaped human antibody. Specifically, humanized antibodies prepared by grafting the CDRs of a non-human animal antibody such as a mouse antibody to a human antibody and such are known. Common genetic engineering techniques for obtaining humanized antibodies are also known. Specifically, for example, overlap extension PCR is known as a method for grafting mouse antibody CDRs to human FRs.

[0156] A vector for expressing a humanized antibody can be produced by inserting a DNA encoding an antibody variable region in which three CDRs and four FRs are ligated and a DNA encoding a human antibody constant region into an expression vector so that these DNAs are fused in frame. After this integration vector is transfected into a host to establish recombinant cells, these cells are cultured, and the DNA encoding the humanized antibody is expressed to produce the humanized antibody in the culture of the cells (see, European Patent Publication No. EP 239,400, and International Patent Publication No. WO 1996/002576).

[0157] As necessary, an amino acid residue in an FR may be substituted so that the CDRs of a reshaped human antibody form an appropriate antigen-binding site. For example, a mutation can be introduced into the amino acid sequence of an FR by applying the PCR method used for grafting mouse CDRs to human FRs.

[0158] A desired human antibody can be obtained by DNA immunization using a transgenic animal having the complete repertoire of human antibody genes (see International Publication Nos. WO 1993/012227, WO 1992/003918, WO 1994/002602, WO 1994/025585, WO 1996/034096, and WO 1996/033735) as an animal for immunization.

[0159] Furthermore, technologies for obtaining a human antibody by panning using a human antibody library are known. For example, a human antibody V region is expressed on the surface of a phage as a single-chain antibody (scFv) by the phage display method. The scFv-expressing phage that binds to the antigen can be selected. The DNA sequence that encodes the V region of the antigen-bound human antibody can be determined by analyzing the genes of the selected phage. After determining the DNA sequence of the scFv that binds to the antigen, an expression vector can be prepared by fusing the V-region sequence in-frame with the sequence of a desired human antibody C region, and then inserting this into a suitable expression vector. The expression vector is introduced into suitable expression cells such as those described above, and the human antibody can be obtained by expressing the human antibody-encoding gene. These methods are already known (see, International Publication Nos. WO 1992/001047, WO 1992/020791, WO 1993/006213, WO 1993/011236, WO 1993/019172, WO 1995/001438, and WO 1995/15388).

[0160] Variable regions constituting the antibodies of the present invention can be variable regions that recognize any antigen.

[0170] One or more amino acid residue alterations are allowed in the amino acid sequences constituting the variable regions as long as their antigen-binding activities are maintained. When altering a variable region amino acid sequence, there is no particularly limitation on the site of alteration and number of amino acids altered. For example, amino acids present in CDR and/or FR can be altered appropriately. When altering amino acids in a variable region, the binding activity is preferably maintained without particular limitation; and for example, as compared to before alteration, the binding activity is 50% or more, preferably 80% or more, and more preferably 100% or more. Furthermore, the binding activity may be increased by amino acid alterations. For example, the binding activity may be 2-, 5-, 10-times higher or such than that before alteration. In the antibodies of the present invention, alteration of amino acid sequence may be at least one of amino acid residue substitution, addition, deletion, and modification.

[0171] For example, the modification of the N-terminal glutamine of a variable region into pyroglutamic acid by pyroglutamylation is a modification well known to those skilled in the art. Thus, when the heavy-chain N terminus is glutamine, the antibodies of the present invention comprise the variable regions in which the glutamine is modified to pyroglutamic acid.

[0172] Antibody variable regions of the present invention may have any sequences, and they may be antibody variable regions of any origin, such as mouse antibodies, rat antibodies, rabbit antibodies, goat antibodies, camel antibodies, humanized antibodies produced by humanizing these non-human antibodies, and human antibodies. "Humanized antibodies", also referred to as "reshaped human antibodies", are antibodies in which the complementarity determining regions (CDRs) of an antibody derived from a non-human mammal, for example, a mouse antibody, are transplanted into the CDRs of a human antibody. Methods for identifying CDRs are known (Kabat et al., Sequence of Proteins of Immunological Interest (1987), National Institute of Health, Bethesda, Md.; Chothia et al., Nature (1989) 342: 877). Their common genetic recombination techniques are also known (see, European Patent Application Publication No. EP 125023 and WO 96/02576). Furthermore, these antibodies may have various amino acid substitutions introduced into their variable regions to improve their antigen binding, pharmacokinetics, stability, and antigenicity. Variable regions of the antibodies of the present invention may be able to bind antigens repeatedly due to their pH dependability in antigen binding (WO 2009/125825).

[0173] .kappa. chain and .lamda. chain-type constant regions are present in antibody light-chain constant regions, but either one of the light chain constant regions is acceptable. Furthermore, light-chain constant regions of the present invention may be light-chain constant regions with amino acid alterations such as substitutions, deletions, additions, and/or insertions.

[0174] For example, for the heavy chain constant regions of an antibody of the present invention, heavy chain constant regions of human IgG antibodies may be used and heavy chain constant regions of human IgG1 antibodies and those of human IgG4 antibodies are preferred.

[0175] Furthermore, polypeptides of the present invention may be made into Fc fusion protein molecules by linking to other proteins, physiologically active peptides, and such.

[0176] Examples of the other proteins and biologically active peptides include receptors, adhesion molecules, ligands, and enzymes, but are not limited thereto.

[0177] Preferred examples of Fc fusion protein molecules of the present invention include proteins with Fc domain fused to a receptor protein that binds to a target, and such examples include TNFR-Fc fusion protein, IL1R-Fc fusion protein, VEGFR-Fc fusion protein, and CTLA4-Fc fusion protein (Nat. Med. 2003 January; 9(1): 47-52; BioDrugs. 2006; 20(3): 151-60). Furthermore, a protein to be fused to a polypeptide of the present invention may be any molecule as long as it binds to a target molecule, and examples include scFv molecules (WO 2005/037989), single-domain antibody molecules (WO 2004/058821; WO 2003/002609), antibody-like molecules (Current Opinion in Biotechnology 2006, 17: 653-658; Current Opinion in Biotechnology 2007, 18: 1-10; Current Opinion in Structural Biology 1997, 7: 463-469; and Protein Science 2006, 15: 14-27) such as DARPins (WO 2002/020565), Affibody (WO 1995/001937), Avimer (WO 2004/044011; WO 2005/040229), and Adnectin (WO 2002/032925). Furthermore, antibodies and Fc fusion protein molecules may be multispecific antibodies that bind to multiple types of target molecules or epitopes.

[0178] Furthermore, the antibodies of the present invention include antibody modification products. Such antibody modification products include, for example, antibodies linked with various molecules such as polyethylene glycol (PEG) and cytotoxic substances. Such antibody modification products can be obtained by chemically modifying antibodies of the present invention. Methods for modifying antibodies are already established in this field.

[0179] The antibodies of the present invention may also be bispecific antibodies. "Bispecific antibody" refers to an antibody that has in a single molecule variable regions that recognize different epitopes. The epitopes may be present in a single molecule or in different molecules.

[0180] The polypeptides of the present invention can be prepared by the methods known to those skilled in the art. For example, the antibodies can be prepared by the methods described below, but the methods are not limited thereto.

[0181] A DNA encoding an antibody heavy chain in which one or more amino acid residues in the Fc region have been substituted with other amino acids of interest and DNA encoding an antibody light chain, are expressed. A DNA encoding a heavy chain in which one or more amino acid residues in the Fc region are substituted with other amino acids of interest can be prepared, for example, by obtaining a DNA encoding the Fc region of a natural heavy chain, and introducing an appropriate substitution so that a codon encoding a particular amino acid in the Fc region encodes another amino acid of interest.

[0182] Alternatively, a DNA encoding a heavy chain in which one or more amino acid residues in the Fc region are substituted with other amino acids of interest can also be prepared by designing and then chemically synthesizing a DNA encoding a protein in which one or more amino acid residues in the Fc region of the natural heavy chain are substituted with other amino acids of interest. The position and type of amino acid substitution are not particularly limited. Furthermore, alteration is not limited to substitution, and alteration may be any of deletion, addition, or insertion, or combination thereof.

[0183] Alternatively, a DNA encoding a heavy chain in which one or more amino acid residues in the Fc region are substituted with other amino acids of interest can be prepared as a combination of partial DNAs. Such combinations of partial DNAs include, for example, the combination of a DNA encoding a variable region and a DNA encoding a constant region, and the combination of a DNA encoding an Fab region and a DNA encoding an Fc region, but are not limited thereto. Furthermore, a DNA encoding a light chain can similarly be prepared as a combination of partial DNAs.

[0184] Methods for expressing the above-described DNAs include the methods described below. For example, a heavy chain expression vector is constructed by inserting a DNA encoding a heavy chain variable region into an expression vector along with a DNA encoding a heavy chain constant region. Likewise, a light chain expression vector is constructed by inserting a DNA encoding a light chain variable region into an expression vector along with a DNA encoding a light chain constant region. Alternatively, these heavy and light chain genes may be inserted into a single vector.

[0185] When inserting a DNA encoding the antibody of interest into an expression vector, the DNA is inserted so that the antibody is expressed under the control of an expression-regulating region such as an enhancer or promoter. Next, host cells are transformed with this expression vector to express the antibody. In such cases, an appropriate combination of host and expression vector may be used.

[0186] Examples of the vectors include M13 vectors, pUC vectors, pBR322, pBluescript, and pCR-Script. Alternatively, when aiming to subclone and excise cDNA, in addition to the vectors described above, pGEM-T, pDIRECT, pT7, and such can be used.

[0187] Expression vectors are particularly useful when using vectors for producing the polypeptides of the present invention. For example, when a host cell is E. coli such as JM109, DH5.alpha., HB101, and XL1-Blue, the expression vectors must carry a promoter that allows efficient expression in E. coli, for example, lacZ promoter (Ward et al., Nature (1989) 341: 544-546; FASEB J. (1992) .delta.: 2422-2427; its entirety are incorporated herein by reference), araB promoter (Better et al., Science (1988) 240: 1041-1043; its entirety are incorporated herein by reference), T7 promoter, or such. Such vectors include pGEX-5.times.-1 (Pharmacia), "QIAexpress system" (Qiagen), pEGFP, or pET (in this case, the host is preferably BL21 that expresses T7 RNA polymerase) in addition to the vectors described above.

[0188] The vectors may contain signal sequences for polypeptide secretion. As a signal sequence for polypeptide secretion, a pelB signal sequence (Lei, S. P. et al J. Bacteriol. (1987) 169: 4379; its entirety are incorporated herein by reference) may be used when a polypeptide is secreted into the E. coli periplasm. The vector can be introduced into host cells by lipofectin method, calcium phosphate method, and DEAE-Dextran method, for example.

[0189] In addition to E. coli expression vectors, the vectors for producing the polypeptides of the present invention include mammalian expression vectors (for example, pcDNA3 (Invitrogen), pEGF-BOS (Nucleic Acids. Res. 1990, 18(17): p5322; its entirety are incorporated herein by reference), pEF, and pCDM8), insect cell-derived expression vectors (for example, the "Bac-to-BAC baculovirus expression system" (Gibco-BRL) and pBacPAK8), plant-derived expression vectors (for example, pMH1 and pMH2), animal virus-derived expression vectors (for example, pHSV, pMV, and pAdexLcw), retroviral expression vectors (for example, pZIPneo), yeast expression vectors (for example, "Pichia Expression Kit" (Invitrogen), pNV11, and SP-Q01), and Bacillus subtilis expression vectors (for example, pPL608 and pKTH50), for example.

[0190] When aiming for expression in animal cells such as CHO, COS, and NIH3T3 cells, the vectors must have a promoter essential for expression in cells, for example, SV40 promoter (Mulligan et al., Nature (1979) 277: 108; its entirety are incorporated herein by reference), MMTV-LTR promoter, EF1.alpha. promoter (Mizushima et al., Nucleic Acids Res. (1990) 18: 5322; its entirety are incorporated herein by reference), CAG promoter (Gene. (1990) 18: 5322; its entirety are incorporated herein by reference), and CMV promoter, and more preferably they have a gene for selecting transformed cells (for example, a drug resistance gene that allows evaluation using an agent (neomycin, G418, or such)). Vectors with such characteristics include pMAM, pDR2, pBK-RSV, pBK-CMV, pOPRSV, and pOP13, for example.

[0191] In addition, the following method can be used for stable gene expression and gene copy number amplification in cells: CHO cells deficient in a nucleic acid synthesis pathway are introduced with a vector that carries a DHFR gene which compensates for the deficiency (for example, pCHOI), and the vector is amplified using methotrexate (MTX). Alternatively, the following method can be used for transient gene expression: COS cells with a gene expressing SV40 T antigen on their chromosome are transformed with a vector with an SV40 replication origin (pcD and such). Replication origins derived from polyoma virus, adenovirus, bovine papilloma virus (BPV), and such can also be used. To amplify gene copy number in host cells, the expression vectors may further carry selection markers such as aminoglycoside transferase (APH) gene, thymidine kinase (TK) gene, E. coli xanthine-guanine phosphoribosyltransferase (Ecogpt) gene, and dihydrofolate reductase (dhfr) gene.

[0192] Antibodies can be collected, for example, by culturing transformed cells, and then separating the antibodies from the inside of the transformed cells or from the culture media. Antibodies can be separated and purified using an appropriate combination of methods such as centrifugation, ammonium sulfate fractionation, salting out, ultrafiltration, 1q, FcRn, protein A, protein G column, affinity chromatography, ion exchange chromatography, and gel filtration chromatography.

[0193] Furthermore, the present invention provides methods for producing a polypeptide comprising an antibody Fc region having maintained or decreased Fc.gamma.RIIa-binding activity, and enhanced Fc.gamma.RIIb-binding activity in comparison with a parent polypeptide, which comprises adding at least one amino acid alteration to the Fc region of the polypeptide.

[0194] Examples include production methods comprising the following steps:

(a) adding at least one amino acid alteration to the Fc region of polypeptides comprising an antibody Fc region; (b) measuring the Fc.gamma.RIIa-binding activity and Fc.gamma.RIIb-binding activity of the polypeptides altered in step (a); and (c) selecting polypeptides having maintained or decreased Fc.gamma.RIIa-binding activity, and enhanced Fc.gamma.RIIb-binding activity in comparison with a parent polypeptide.

[0195] A preferred embodiment is a method for producing a polypeptide comprising an antibody Fc region, which comprises the steps of:

(a) altering a nucleic acid encoding the polypeptide so that the Fc.gamma.RIIa-binding activity is maintained or decreased, and the Fc.gamma.RIIb-binding activity is enhanced in comparison with the parent peptide; (b) introducing the nucleic acid into host cells and culturing them to induce expression; and (c) collecting the polypeptide from the host cell culture.

[0196] Furthermore, antibodies and Fc fusion protein molecules produced by this production method are also included in the present invention.

[0197] The present invention also provides methods for producing a polypeptide in which antibody production against the polypeptide is suppressed compared with its parent polypeptide when administered in vivo, which comprise adding at least one amino acid alteration in the Fc region of a polypeptide comprising an antibody Fc region.

[0198] Examples include a production method comprising the following steps:

(a) adding at least one amino acid alteration in the Fc region of a polypeptide comprising an antibody Fc region; and (b) confirming that antibody production is suppressed when the polypeptide altered in step (a) is administered in vivo in comparison with a parent polypeptide.

[0199] Whether or not production of antibodies against the polypeptide has been suppressed can be confirmed by methods of administering the polypeptide to an animal and such. Alternatively, suppression of antibody production can be determined by measuring the binding activities towards Fc.gamma.RIIa and Fc.gamma.RIIb, and observing an increase in the value obtained by dividing the KD value for Fc.gamma.RIIa by the KD value for Fc.gamma.RIIb. Such polypeptides are considered to be useful as pharmaceuticals since they can suppress antibody production without activating Fc.gamma.R.

[0200] In the above-mentioned production method, it is preferable to enhance the Fc.gamma.RIIb-binding activity, and maintain or decrease the binding activities towards Fc.gamma.RIIa (type R) and Fc.gamma.RIIa (type H); and it is preferable to additionally reduce binding activities towards Fc.gamma.RIa and/or Fc.gamma.RIIIa.

[0201] In a preferred embodiment in the above-mentioned production method, for example, a polypeptide comprising a human IgG Fc region is altered so that Pro at position 238 (EU numbering) is substituted with Asp or Leu at position 328 (EU numbering) is substituted with Glu.

Other preferred embodiments include altering the polypeptide so that at least one substitution selected from the group consisting of:

<Pharmaceutical Compositions>

[0213] The present invention provides pharmaceutical compositions comprising the polypeptide of the present invention.

[0214] The pharmaceutical compositions of the present invention can be formulated, in addition to the antibody or Fc-fusion protein molecules of the present invention described above, with pharmaceutically acceptable carriers by known methods. For example, the compositions can be used parenterally, when the antibodies are formulated in a sterile solution or suspension for injection using water or any other pharmaceutically acceptable liquid. For example, the compositions can be formulated by appropriately combining the antibodies or Fc-fusion protein molecules with pharmaceutically acceptable carriers or media, specifically, sterile water or physiological saline, vegetable oils, emulsifiers, suspending agents, surfactants, stabilizers, flavoring agents, excipients, vehicles, preservatives, binding agents, and such, by mixing them at a unit dose and form required by generally accepted pharmaceutical implementations. Specific examples of the carriers include light anhydrous silicic acid, lactose, crystalline cellulose, mannitol, starch, carmellose calcium, carmellose sodium, hydroxypropyl cellulose, hydroxypropyl methylcellulose, polyvinylacetal diethylaminoacetate, polyvinylpyrrolidone, gelatin, medium-chain triglyceride, polyoxyethylene hardened castor oil 60, saccharose, carboxymethyl cellulose, corn starch, inorganic salt, and such. The content of the active ingredient in such a formulation is adjusted so that an appropriate dose within the required range can be obtained.

[0215] Sterile compositions for injection can be formulated using vehicles such as distilled water for injection, according to standard protocols.

[0216] Aqueous solutions used for injection include, for example, physiological saline and isotonic solutions containing glucose or other adjuvants such as D-sorbitol, D-mannose, D-mannitol, and sodium chloride. These can be used in conjunction with suitable solubilizers such as alcohol, specifically ethanol, polyalcohols such as propylene glycol and polyethylene glycol, and non-ionic surfactants such as Polysorbate 80.TM. and HCO-50.

[0217] Oils include sesame oils and soybean oils, and can be combined with solubilizers such as benzyl benzoate or benzyl alcohol. These may also be formulated with buffers, for example, phosphate buffers or sodium acetate buffers; analgesics, for example, procaine hydrochloride; stabilizers, for example, benzyl alcohol or phenol; or antioxidants. The prepared injections are typically aliquoted into appropriate ampules.

[0218] The administration is preferably carried out parenterally, and specifically includes injection, intranasal administration, intrapulmonary administration, and percutaneous administration. For example, injections can be administered systemically or locally by intravenous injection, intramuscular injection, intraperitoneal injection, or subcutaneous injection.

[0219] Furthermore, the method of administration can be appropriately selected according to the age and symptoms of the patient. A single dosage of the pharmaceutical composition containing an antibody or a polynucleotide encoding an antibody can be selected, for example, from the range of 0.0001 to 1,000 mg per kg of body weight. Alternatively, the dosage may be, for example, in the range of 0.001 to 100,000 mg/patient. However, the dosage is not limited to these values. The dosage and method of administration vary depending on the patient's body weight, age, and symptoms, and can be appropriately selected by those skilled in the art.

[0220] The above-mentioned polypeptides of the present invention are useful as active ingredients of pharmaceutical agents that suppress the activation of B cells, mast cells, dendritic cells, and/or basophils. Polypeptides of the present invention can suppress the activation of B cells, mast cells, dendritic cells, and/or basophils, by selectively working on Fc.gamma.RIIb without activating Fc.gamma.R. B cell activation includes proliferation, IgE production, IgM production, and IgA production. The above-mentioned polypeptides of the present invention cross-link Fc.gamma.RIIb with IgE to suppress IgE production of B cells, with IgM to suppress IgM production of B cells, and with IgA to suppress IgA production. Other than the above, suppressive effects similar to those mentioned above are exhibited by directly or indirectly cross-linking Fc.gamma.RIIb with molecules that are expressed on B cells and comprise the ITAM domain inside the cell or interact with the ITAM domain such as BCR, CD19, and CD79b. Furthermore, activation of mast cells includes proliferation, activation by IgE and such, and degranulation. In mast cells, the above-mentioned polypeptides of the present invention can suppress proliferation, activation by IgE and such, and degranulation by directly or indirectly cross-linking Fc.gamma.RIIb with IgE receptor molecules that are expressed on mast cells and comprise the ITAM domain or interact with the ITAM domain such as Fc.epsilon.RI, DAP12, and CD200R3. Activation of basophils includes proliferation and degranulation of basophils. Also in basophils, the above-mentioned polypeptides of the present invention can suppress proliferation, activation, and degranulation by directly or indirectly cross-linking Fc.gamma.RIIb with molecules on the cell membrane, which comprise the ITAM domain inside the cell or interact with the ITAM domain. Activation of dendritic cells includes proliferation and degranulation of dendritic cells. Also in dendritic cells, the above-mentioned polypeptides of the present invention can suppress activation, degranulation, and proliferation by directly or indirectly cross-linking Fc.gamma.RIIb with molecules on the cell membrane, which comprise the ITAM domain inside the cell or interact with the ITAM domain.

[0221] In the present invention, the polypeptides of the present invention mentioned above are useful as an active ingredient of therapeutic agents or preventive agents for immunological inflammatory diseases. As described above, since polypeptides of the present invention can suppress activation of B cells, mast cells, dendritic cells and/or basophils, administration of the polypeptides of the present invention as a result can treat or prevent immunological inflammatory diseases. Without being limited thereto, the term "immunological inflammatory diseases" comprises, rheumatoid arthritis, autoimmune hepatitis, autoimmune thyroiditis, autoimmune blistering diseases, autoimmune adrenocortical disease, autoimmune hemolytic anemia, autoimmune thrombocytopenic purpura, megalocytic anemia, autoimmune atrophic gastritis, autoimmune neutropenia, autoimmune orchitis, autoimmune encephalomyelitis, autoimmune receptor disease, autoimmune infertility, chronic active hepatitis, glomerulonephritis, interstitial pulmonary fibrosis, multiple sclerosis, Paget's disease, osteoporosis, multiple myeloma, uveitis, acute and chronic spondylitis, gouty arthritis, inflammatory bowel disease, adult respiratory distress syndrome (ARDS), psoriasis, Crohn's disease, Basedow's disease, juvenile diabetes, Addison's disease, myasthenia gravis, lens-induced uveitis, systemic lupus erythematosus, allergic rhinitis, allergic dermatitis, ulcerative colitis, hypersensitivity, muscle degeneration, cachexia, systemic scleroderma, localized scleroderma, Sjogren's syndrome, Behchet's disease, Reiter's syndrome, type I and type II diabetes, bone resorption disorder, graft-versus-host reaction, ischemia-reperfusion injury, atherosclerosis, brain trauma, cerebral malaria, sepsis, septic shock, toxic shock syndrome, fever, malgias due to staining, aplastic anemia, hemolytic anemia, idiopathic thrombocytopenia, Goodpasture's syndrome, Guillain-Barre syndrome, Hashimoto's thyroiditis, pemphigus, IgA nephropathy, pollinosis, antiphospholipid antibody syndrome, polymyositis, Wegener's granulomatosis, arteritis nodosa, mixed connective tissue disease, fibromyalgia, asthma, atopic dermatitis, chronic atrophic gastritis, primary biliary cirrhosis, primary sclerosing cholangitis, autoimmune pancreatitis, aortitis syndrome, rapidly progressive glomerulonephritis, megaloblastic anemia, idiopathic thrombocytopenic purpura, primary hypothyroidism, idiopathic Addison's disease, insulin-dependent diabetes mellitus, chronic discoid lupus erythematosus, pemphigoid, herpes gestationis, linear IgA bullous dermatosis, epidermolysis bullosa acquisita, alopecia greata, vitiligo vulgaris, leukoderma acquisitum centrifugum of Sutton, Harada's disease, autoimmune optic neuropathy, idiopathic azoospermia, habitual abortion, hypoglycemia, chronic urticaria, ankylosing spondylitis, psoriatic arthritis, enteropathic arthritis, reactive arthritis, spondyloarthropathy, enthesopathy, irritable bowel syndrome, chronic fatigue syndrome, dermatomyositis, inclusion body myositis, Schmidt's syndrome, Graves' disease, pernicious anemia, lupoid hepatitis, presenile dementia, Alzheimer's disease, demyelinating disorder, amyotrophic lateral sclerosis, hypoparathyroidism, Dressler's syndrome, Eaton-Lambert syndrome, dermatitis herpetiformis, alopecia, progressive systemic sclerosis, CREST syndrome (calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyl), and telangiectasia), sarcoidosis, rheumatic fever, erythema multiforme, Cushing's syndrome, transfusion reaction, Hansen's disease, Takayasu arteritis, polymyalgia rheumatica, temporal arteritis, giant cell arthritis, eczema, lymphomatoid granulomatosis, Kawasaki disease, endocarditis, endomyocardial fibrosis, endophthalmitis, fetal erythroblastosis, eosinophilic fasciitis, Felty syndrome, Henoch-Schonlein purpura, transplant rejection, mumps, cardiomyopathy, purulent arthritis, familial Mediterranean fever, Muckle-Wells syndrome, and hyper-IgD syndrome.

[0222] Furthermore, in autoimmune diseases which may be caused by production of antibodies against autoantigens (autoantibodies), the polypeptides of the present invention mentioned above are useful as an active ingredient of pharmaceutical agents for treating or preventing the autoimmune diseases by suppressing production of those autoantibodies. Use of a molecule produced by fusing an antibody Fc portion with AchR (an autoantigen of myasthenia gravis) has been reported to suppress proliferation of B cells which express AchR-recognizing BCR, and induce apoptosis (J. Neuroimmunol, 227: 35-43, 2010). Use of a fusion protein formed between an antigen recognized by an autoantibody and an antibody Fc region of the present invention enables crosslinking of Fc.gamma.RIIb with BCR of a B cell expressing BCR for that autoantigen, suppression of proliferation of B cells expressing BCR for the autoantigen, and induction of apoptosis. Such autoimmune diseases include Guillain-Barre syndrome, myasthenia gravis, chronic atrophic gastritis, autoimmune hepatitis, primary biliary cirrhosis, primary sclerosing cholangitis, autoimmune pancreatitis, aortitis syndrome, Goodpasture's syndrome, rapidly progressive glomerulonephritis, megaloblastic anemia, autoimmune hemolytic anemia, autoimmune neutropenia, idiopathic thrombocytopenic purpura, Basedow's disease, Hashimoto's thyroiditis, primary hypothyroidism, idiopathic Addison's disease, insulin-dependent diabetes mellitus, chronic discoid lupus erythematosus, localized scleroderma, pemphigus, pemphigoid, herpes gestationis, linear IgA bullous dermatosis, epidermolysis bullosa acquisita, alopecia greata, vitiligo vulgaris, leukoderma acquisitum centrifugum of Sutton, Harada's disease, autoimmune optic neuropathy, idiopathic azoospermia, habitual abortion, type II diabetes, hypoglycemia, and chronic urticaria; but are not limited thereto.

[0223] Furthermore, the above-mentioned polypeptides of the present invention are useful as an active ingredient in therapeutic agents for diseases with deficiency of a biologically essential protein. For diseases with deficiency of a biologically essential protein, therapeutic methods that administer and supplement the protein as a pharmaceutical agent are used. However, since the patient lacks the protein from the beginning, the externally supplemented protein is recognized as a foreign substance and antibodies against that protein are produced. As a result, the protein becomes easily removed, and the effect as a pharmaceutical is reduced. Use of a fusion protein comprising such a protein and an antibody Fc region of the present invention enables crosslinking between Fc.gamma.RIIb and BCR on B cells that recognize the protein, and enables suppression of antibody production against the protein. The proteins to be supplemented include Factor VIII, Factor IX, TPO, EPO, .alpha.-iduronidase, iduronate sulfatase, A-type heparan N-sulfatase, B type .alpha.-N-acetylglucosaminidase, C type acetyl CoA: .alpha.-glucosaminidase acetyltransferase, D type N-acetylglucosamine 6-sulfatase, galactose 6-sulfatase, N-acetylgalactosamine 4-sulfatase, .beta.-glucuronidase, .alpha.-galactosidase, acidic .alpha.-galactosidase, and glucocerebrosidase. These proteins may be supplemented for diseases such as hemophilia, idiopathic thrombocytopenic purpura, renal anemia, and lysosomal disease (mucopolysaccharidosis, Fabry's disease, Pompe disease, and Gaucher's disease), without being limited thereto.

[0224] Furthermore, the above-mentioned polypeptides of the present invention are useful as an active ingredient for antiviral agents. Antibodies that comprise an Fc region of the present invention and are anti-virus antibodies can suppress antibody-dependent enhancement observed with anti-virus antibodies. Antibody-dependent enhancement is a phenomenon where a virus uses neutralizing antibodies against the virus to become phagocytosed via activating Fc.gamma.Rs, and infects Fc.gamma.R-expressing cells so that the infection spreads. Binding of anti-dengue-virus neutralizing antibodies to Fc.gamma.RIIb has been reported to play an important role in suppressing antibody-dependent enhancement (Proc. Natl. Acad. Sci. USA, 108: 12479-12484, 2011). Crosslinking Fc.gamma.RIIb with an immunocomplex with dengue virus, which is formed by the anti-dengue-virus neutralizing antibodies, inhibits Fc.gamma.R-mediated phagocytosis, resulting in the suppression of antibody-dependent enhancement. Examples of such viruses include dengue virus (DENV1, DENV2, and DENV4) and HIV, but are not limited thereto.

[0225] Furthermore, polypeptides of the present invention described above are useful as an active ingredient in preventive agents or therapeutic agents for arteriosclerosis. Antibodies against oxidized LDL, i.e., a cause for arteriosclerosis, which are antibodies comprising an Fc region of the present invention, can prevent Fc.gamma.RIIa-dependent adhesion of inflammatory cells. It has been reported that while anti-oxidized LDL antibodies inhibit the interaction between oxidized LDL and CD36, anti-oxidized LDL antibodies bind to endothelial cells, and monocytes recognize their Fc portion in an Fc.gamma.RIIa-dependent or Fc.gamma.RI-dependent manner; and this leads to adhesion (Immunol. Lett., 108: 52-61, 2007). Using antibodies comprising an Fc region of the present invention for such antibodies may inhibit Fc.gamma.RIIa-dependent binding and suppress monocyte adhesion by Fc.gamma.RIIb-mediated inhibitory signals.

[0226] Herein, polypeptides of the present invention described above are useful as an active ingredient in therapeutic agents or preventive agents for cancer. As described above, it is known that enhancing the Fc.gamma.RIIb binding enhances the agonistic activity of an agonist antibody, and enhances the antitumor effect of the antibody. Therefore, agonist antibodies using the Fc region of the present invention are useful for treatment or prevention of cancer. The Fc region of the present invention enhances the agonistic activity of agonist antibodies against receptors of the TNF receptor family such as Aliases, CD120a, CD120b, Lymphotoxin 13 receptor, CD134, CD40, FAS, TNFRSF6B, CD27, CD30, CD137, TNFRSF10A, TNFRSF10B, TNFRSF10C, TNFRSF10D, RANK, Osteoprotegerin, TNFRSF12A, TNFRSF13B, TNFRSF13C, TNFRSF14, Nerve growth factor receptor, TNFRSF17, TNFRSF18, TNFRSF19, TNFRSF21, TNFRSF25, and Ectodysplasin A2 receptor. Furthermore, the agonistic activity of agonist antibodies other than those described above is also enhanced. Without being limited thereto, cancer includes lung cancer (including small cell lung cancer, non-small cell lung cancer, pulmonary adenocarcinoma, and squamous cell carcinoma of the lung), large intestine cancer, rectal cancer, colon cancer, breast cancer, liver cancer, gastric cancer, pancreatic cancer, renal cancer, prostate cancer, ovarian cancer, thyroid cancer, cholangiocarcinoma, peritoneal cancer, mesothelioma, squamous cell carcinoma, cervical cancer, endometrial cancer, bladder cancer, esophageal cancer, head and neck cancer, nasopharyngeal cancer, salivary gland tumor, thymoma, skin cancer, basal cell tumor, malignant melanoma, anal cancer, penile cancer, testicular cancer, Wilms' tumor, acute myeloid leukemia (including acute myeloleukemia, acute myeloblastic leukemia, acute promyelocytic leukemia, acute myelomonocytic leukemia, and acute monocytic leukemia), chronic myelogenous leukemia, acute lymphoblastic leukemia, chronic lymphatic leukemia, Hodgkin's lymphoma, non-Hodgkin's lymphoma (Burkitt's lymphoma, chronic lymphocytic leukemia, mycosis fungoides, mantle cell lymphoma, follicular lymphoma, diffuse large-cell lymphoma, marginal zone lymphoma, pilocytic leukemia plasmacytoma, peripheral T-cell lymphoma, and adult T cell leukemia/lymphoma), Langerhans cell histiocytosis, multiple myeloma, myelodysplastic syndrome, brain tumor (including glioma, astroglioma, glioblastoma, meningioma, and ependymoma), neuroblastoma, retinoblastoma, osteosarcoma, Kaposi's sarcoma, Ewing's sarcoma, angiosarcoma, and hemangiopericytoma.

[0227] Furthermore, the present invention relates to methods for treating or preventing immunological inflammatory diseases, which comprise the step of administering to a subject (patient) a polypeptide of the present invention or a polypeptide produced by production methods of the present invention.

[0228] The present invention also provides kits for use in the therapeutic methods or preventive methods of the present invention, which comprises at least a polypeptide of the present invention or a polypeptide produced by production methods of the present invention, or a pharmaceutical composition of the present invention. In addition, pharmaceutically acceptable carriers, media, instructions on the method of use, and such may be included in the kit. Furthermore, the present invention relates to use of a polypeptide of the present invention or a polypeptide produced by production methods of the present invention in the production of agents for treating or preventing immunological inflammatory diseases. The present invention also relates to polypeptides of the present invention or polypeptides produced by production methods of the present invention for use in the therapeutic methods or preventive methods of the present invention.

Example 1

Comprehensive Analysis of the Binding of Fc Variants to Fc.gamma.R

[0234] Mutations were introduced into IgG1 antibodies to generate antibodies that have decreased Fc-mediated binding towards activating Fc.gamma.R, specifically both allotypes of Fc.gamma.RIIa, types H and R, as well as enhanced Fc.gamma.RIIb binding relative to IgG1; and binding to each Fc.gamma.R was analyzed comprehensively.

[0235] The variable region (SEQ ID NO: 15) of a glypican 3 antibody comprising the CDR of GpH7 which is an anti-glypican 3 antibody with improved plasma kinetics disclosed in WO 2009/041062 was used as the common antibody H chain. Similarly, for the common antibody L chain, GpL16-k0 (SEQ ID NO: 16) of the glypican 3 antibody with improved plasma kinetics disclosed in WO 2009/041062 was used. Furthermore, B3 (SEQ ID NO: 17) in which a K439E mutation has been introduced into G1d produced by removing the C terminal Gly and Lys of IgG1 was used as the antibody H chain constant region. This H chain is referred to as GpH7-B3 (SEQ ID NO: 18), and the L chain is referred to as GpL16-k0 (SEQ ID NO: 16).

[0236] With respect to GpH7-B3, the amino acids that are considered to be involved in Fc.gamma.R binding and the surrounding amino acids (positions 234 to 239, 265 to 271, 295, 296, 298, 300, and 324 to 337, according to EU numbering) were substituted respectively with 18 types of amino acids excluding the original amino acids and Cys. These Fc variants are referred to as B3 variants. B3 variants were expressed and purified using the method of Reference Example 1, and the binding to each Fc.gamma.R (Fc.gamma.RIa, Fc.gamma.RIIa type H, Fc.gamma.RIIa type R, Fc.gamma.RIIb, and Fc.gamma.RIIIa) was comprehensively evaluated using the method of Reference Example 2.

[0237] Figures were produced based on the results of interaction analysis with each Fc.gamma.R by the method below. The value of the amount of Fc.gamma.R binding of each B3 variant-derived antibody was divided by the value of the amount of Fc.gamma.R binding of the antibody used for comparison which does not have mutations introduced into B3 (an antibody having the sequence of a naturally-occurring human IgG1 at positions 234 to 239, 265 to 271, 295, 296, 298, 300, and 324 to 337, according to EU numbering). The value obtained by multiplying this value by 100 was used as an indicator of the relative Fc.gamma.R-binding activity of each variant. The horizontal axis shows the value of the relative Fc.gamma.RIIb-binding activity of each variant, and the vertical axis shows the value of the respective relative binding activity of each variant towards activating Fc.gamma.Rs: Fc.gamma.RIa, Fc.gamma.RIIa type H, Fc.gamma.RIIa type R, and Fc.gamma.RIIIa (FIGS. 1, 2, 3, and 4).

[0238] As shown by labels in FIGS. 1-4, the results show that of all alterations, when only mutations called mutation A (alteration produced by substituting Pro at position 238 (EU numbering) with Asp) and mutation B (alteration produced by substituting Leu at position 328 (EU numbering) with Glu) were introduced, there were remarkable enhancement of binding to Fc.gamma.RIIb and remarkable suppression of binding to both types of Fc.gamma.RIIa compared with before the introduction.

Example 2

SPR Analysis of Variants that Selectively Bind to Fc.gamma.RIIb

[0239] With regard to the alteration identified in Example 1 where Pro at position 238 (EU numbering) is substituted with Asp, the binding to each Fc.gamma.R was analyzed in detail. The variable region of IL6R-H (SEQ ID NO: 19), which is the variable region of the antibody against the human interleukin 6 receptor disclosed in WO 2009/125825, was used as the antibody H chain variable region, and IL6R-G1d (SEQ ID NO: 20) which comprises G1d with deletion of C-terminal Gly and Lys of human IgG1 was used as the antibody H chain constant region in the IgG1 H chain. Pro at position 238 (EU numbering) in IL6R-G1d was substituted with Asp to produce IL6R-G1d-v1 (SEQ ID NO: 21). Next, Leu at position 328 (EU numbering) in IL6R-G1d was substituted with Glu to produce IL6R-G1d-v2 (SEQ ID NO: 23). Furthermore, for comparison, Ser at position 267 (EU numbering) was substituted with Glu, and Leu at position 328 (EU numbering) was substituted with Phe in IL6R-G1d to produce IL6R-G1d-v3 (SEQ ID NO: 24) as described in Non-patent Document 27. IL6R-L (SEQ ID NO: 22), which is the L chain of tocilizumab, was utilized as a mutual antibody L chain; and together with each H chain, the antibodies were expressed and purified according to the method of Reference Example 1. The obtained antibodies which comprise an amino acid sequence derived from IL6R-G1d, IL6R-G1d-v1, IL6R-G1d-v2, or IL6R-G1d-v3 as the antibody H chain are referred to as IgG1, IgG1-v1, IgG1-v2, and IgG1-v3, respectively.

[0240] Next, kinetic analysis of interactions between these antibodies and Fc.gamma.R was carried out using Biacore T100 (GE Healthcare). HBS-EP+ (GE Healthcare) was used as the running buffer, and the measurement temperature was set to 25.degree. C. A chip produced by immobilizing Protein A onto a Series S Sensor Chip CMS (GE Healthcare) by the amine-coupling method was used. An antibody of interest was captured onto this chip to interact with each Fc.gamma.R that had been diluted with the running buffer, and binding to the antibody was measured. After the measurement, the antibody captured on the chip was washed off by allowing reaction with 10 mM glycine-HCl, pH 1.5, and the chip was regenerated and used repeatedly. The sensorgrams obtained as measurement results were analyzed by the 1:1 Langmuir binding model using the Biacore Evaluation Software to calculate the binding rate constant ka (L/mol/s) and dissociation rate constant kd (1/s), and the dissociation constant KD (mol/L) was calculated from these values.

[0241] This time, since the binding of IgG1-v1 and IgG1-v2 to Fc.gamma.RIIa type H and to Fc.gamma.RIIIa was weak, kinetic parameters such as KD could not be calculated from the above-mentioned analytical method. Regarding such interactions, KD values were calculated using the following 1:1 binding model described in Biacore T100 Software Handbook BR1006-48 Edition AE.

[0242] The behavior of interacting molecules according to the 1:1 binding model on Biacore can be described by Equation 1 shown below.

R.sub.eq=CR.sub.max/(KD+C)+RI [Equation 1]

R.sub.eq: a plot of steady-state binding levels against analyte concentration C: concentration RI: bulk refractive index contribution in the sample R.sub.max: analyte binding capacity of the surface

[0243] When this equation is rearranged, KD can be expressed as Equation 2 shown below.

KD=CR.sub.max/(R.sub.eq-RI)--C [Equation 2]

[0244] KD can be calculated by substituting the values of R.sub.max, RI, and C into this equation. From the current measurement conditions, RI=0, C=2 .mu.mol/L can be used. Furthermore, the R.sub.max value obtained when globally fitting the sensorgram obtained as a result of analyzing the interaction of each Fc.gamma.R with IgG1 using the 1:1 Langmuir binding model was divided by the amount of IgG1 captured, this was multiplied by the amount of IgG1-v1 and IgG1-v2 captured, and the resulting value was used as R.sub.max. This calculation is based on the hypothesis that the limit quantity of each Fc.gamma.R that can be bound by IgG1 remains unchanged for all variants produced by introducing mutations into IgG1, and the R.sub.max at the time of measurement is proportional to the amount of antibody bound on the chip at the time of measurement. R.sub.eq was defined as the amount of binding of each Fc.gamma.R to each variant on the sensor chip observed at the time of measurement.

[0245] Under these measurement conditions, the amount of binding (R.sub.eq) of IgG1-v1 and IgG1-v2 to Fc.gamma.RIIa type H was approximately 2.5 RU and 10 RU, respectively, and the amount of binding (R.sub.eq) of IgG1-v1 and IgG1-v2 to Fc.gamma.RIIIa was approximately 2.5 RU and 5 RU, respectively. The amount of IgG1, IgG1-v1, and IgG1-v2 captured in the analysis of interactions with H-type Fc.gamma.RIIa was 452 RU, 469.2 RU, and 444.2 RU, respectively, and the amount of IgG1, IgG1-v1, and IgG1-v2 captured in the analysis of interactions with Fc.gamma.RIIIa was 454.5 RU, 470.8 RU, and 447.1 RU, respectively. The R.sub.max values obtained from global fitting of sensorgrams obtained as a result of analyzing the interaction of IgG1 with H-type Fc.gamma.RIIa and Fc.gamma.RIIIa using the 1:1 Langmuir binding model were 69.8 RU and 63.8 RU, respectively. When these values were used, the calculated R.sub.max values of IgG1-v1 and IgG1-v2 to Fc.gamma.RIIa type H were 72.5 RU and 68.6 RU, respectively, and the calculated R.sub.max values of IgG1-v1 and IgG1-v2 to Fc.gamma.RIIIa were 66.0 RU and 62.7 RU, respectively. These values were substituted into Equation 2 to calculate the KD of IgG1-v1 and IgG1-v2 for Fc.gamma.RIIa type H and Fc.gamma.RIIIa.

KD=CR.sub.max/(R.sub.eq-RI)-C [Equation 2]

[0246] The KD values of IgG1, IgG1-v1, IgG1-v2, and IgG1-v3 for each Fc.gamma.R (the KD values of each antibody for each Fc.gamma.R) are shown in Table 1, and the relative KD values of IgG1-v1, IgG1-v2, and IgG1-v3 obtained by taking the KD values of IgG1 for each Fc.gamma.R and dividing them by the KD values of IgG1-v1, IgG1-v2, and IgG1-v3 for each Fc.gamma.R (the relative KD values of each antibody for each Fc.gamma.R) are shown in Table 2.

TABLE-US-00001 TABLE 1 IgG1 IgG1-v1 IgG1-v2 IgG1-v3 Fc.gamma.RIa 3.4E-10 7.3E-09 4.6E-10 1.9E-10 Fc.gamma.RIIa R 1.2E-06 1.2E-05 2.9E-06 2.3E-09 Fc.gamma.RIIa H 7.7E-07 5.6E-05* 1.2E-05* 1.5E-06 Fc.gamma.RIIb 5.3E-06 1.1E-06 2.3E-06 1.3E-08 Fc.gamma.RIIIa 3.1E-06 5.1E-05* 2.3E-05* 8.8E-06 (mol/L) In Table 1 shown above, "*" means that the KD value was calculated using Equation 2 because binding of Fc.gamma.R to IgG was not sufficiently observed.

KD=CR.sub.max/(R.sub.eq-RI)-C [Equation 2]

TABLE-US-00002 TABLE 2 IgG1-v1 IgG1-v2 IgG1-v3 Fc.gamma.RIa 0.047 0.74 1.8 Fc.gamma.RIIa R 0.10 0.41 522 Fc.gamma.RIIa H 0.014 0.064 0.51 Fc.gamma.RIIb 4.8 2.3 408 Fc.gamma.RIIIa 0.061 0.14 0.35 (THE VALUE OBTAINED BY DIVIDING THE KD VALUE OF IgG1 FOR EACH Fc.gamma.R BY THE KD VALUE OF EACH ANTIBODY IgG1 FOR EACH Fc.gamma.R)

[0247] According to Table 2, when compared with that of IgG1, the binding activity of IgG1-v1 was decreased to 0.047-fold for Fc.gamma.RIa, decreased to 0.10-fold for Fc.gamma.RIIa type R, decreased to 0.014-fold for Fc.gamma.RIIa type H, decreased to 0.061-fold for Fc.gamma.RIIIa, and increased to 4.8-fold for Fc.gamma.RIIb.

[0248] Furthermore, according to Table 2, when compared with that of IgG1, the binding activity of IgG1-v2 was decreased to 0.74-fold for Fc.gamma.RIa, decreased to 0.41-fold for Fc.gamma.RIIa type R, decreased to 0.064-fold for Fc.gamma.RIIa type H, decreased to 0.14-fold for Fc.gamma.RIIIa, and increased to 2.3-fold for Fc.gamma.RIIb.

[0249] More specifically, these results demonstrated that IgG1-v1 having an alteration of substituting Pro at position 238 (EU numbering) with Asp and IgG1-v2 having an alteration of substituting Leu at position 328 (EU numbering) with Glu have the properties of weakening the binding to all activating Fc.gamma.Rs including both allotypes of Fc.gamma.RIIa, while enhancing the binding to Fc.gamma.RIIb which is an inhibitory Fc.gamma.R.

[0250] Next, selectivity of the obtained variant to Fc.gamma.RIIb was evaluated by using the ratio of Fc.gamma.RIIb-binding activity to the binding activity towards type R or type H of Fc.gamma.RIIa as the indicator. Specifically, I/A(R) or I/A(H), which is a value obtained by dividing the KD value for Fc.gamma.RIIa type R or type H by the KD value for Fc.gamma.RIIb, was used as an indicator for the selectivity of Fc.gamma.RIIb with respect to each Fc.gamma.RIIa. This indicator has a greater value when the KD value for Fc.gamma.RIIb becomes smaller or when the KD value for Fc.gamma.RIIa becomes larger. That is, a variant that shows a larger value shows an increased binding activity for Fc.gamma.RIIb relative to Fc.gamma.RIIa. These indicators are summarized in Table 3 for each variant.

TABLE-US-00003 TABLE 3 IgG1 IgG1-v1 IgG1-v2 IgG1-v3 I/A (R) 0.23 11 1.3 0.18 I/A (H) 0.15 51 5.2 115

[0251] According to the results of Table 3, in comparison with IgG1, IgG1-v3 which was produced by applying the existing technology showed a greater 1/A(H) value than that of IgG1 and a greater selectivity for Fc.gamma.RIIb, but a smaller 1/A(R) value than that of IgG1 and an improved selectivity for Fc.gamma.RIIb. On the other hand, IgG1-v1 and IgG1-v2 found in the Examples have larger I/A(R) and I/A(H) values than those of IgG1, and improved selectivity for Fc.gamma.RIIb over both allotypes of Fc.gamma.RIIa.

[0252] So far, alterations having such properties have not been reported, and they are in fact very rare as shown in FIGS. 1, 2, 3, and 4. Alterations produced by substituting Pro at position 238 (EU numbering) with Asp or substituting Leu at position 328 (EU numbering) with Glu are very useful for the development of therapeutic agents for immunological inflammatory diseases and such.

[0253] Furthermore, Table 2 shows that IgG1-v3 described in Non-Patent Document 27 certainly shows a 408-fold enhanced binding to Fc.gamma.RIIb, while the binding to Fc.gamma.RIIa type H is decreased to 0.51 fold, and the binding to Fc.gamma.RIIa type R is enhanced to 522 fold. According to these results, since IgG1-v1 and IgG1-v2 suppress their binding to both Fc.gamma.RIIa types R and H, and enhance their binding to Fc.gamma.RIIb, they are considered to be variants that bind with a greater Fc.gamma.RIIb selectivity compared with IgG1-v3. Specifically, alterations produced by substituting Pro at position 238 (EU numbering) with Asp or substituting Leu at position 328 (EU numbering) with Glu are very useful for the development of therapeutic agents for immunological inflammatory diseases and such.

Example 3

Effects of Combining Fc.gamma.RIIb-Selective Binding Alterations with Other Fc Region Amino Acid Substitutions

[0254] Further enhancement of the selectivity for Fc.gamma.RIIb was attempted based on the variant which has improved selectivity for Fc.gamma.RIIb and has a substitution of Pro at position 238 (EU numbering) with Asp found in Examples 1 and 2.

[0255] First, into IL6R-G1d_v1 (SEQ ID NO: 21) produced by introducing into IL6R-G1d the alteration produced by substituting Pro at position 238 (EU numbering) with Asp, the substitution of Leu at position 328 (EU numbering) with Glu as described in Example 2 which enhances selectivity for Fc.gamma.RIIb was introduced to produce the IL6R-G1d-v4 variant (SEQ ID NO: 25). This was combined with IL6R-L (SEQ ID NO: 22) and prepared according to the method of Reference Example 1. The obtained antibody having the amino acid sequence derived from IL6R-G1d-v4 as the antibody H chain has been named IgG1-v4. The binding activities of IgG1, IgG1-v1, IgG1-v2, and IgG1-v4 to Fc.gamma.RIIb were evaluated according to the method of Reference Example 2, and those results are shown in Table 4.

TABLE-US-00004 TABLE 4 Relative KD for KD for Fc.gamma.RIIb (KD of Fc.gamma.RIIb IgG1/KD Variant Alteration (mol/L) of each variant) IgG1 -- 5.30E-06 1 IgG1-v1 Substitution of Pro at position 1.10E-06 4.8 238 (EU numbering) with Asp IgG1-v2 Substitution of Leu at position 2.30E-06 2.3 328 (EU numbering) with Glu IgG1-v4 Substitution of Pro at position 1.10E-05 0.47 238 (EU numbering) with Asp and substitution of Leu at position 328 (EU numbering) with Glu

[0256] From the results of Table 4, since L328E improves the Fc.gamma.RIIb-binding activity by 2.3 fold compared with IgG1, combining it with P238D which similarly improves the Fc.gamma.RIIb-binding activity by 4.8 fold compared with IgG1 was anticipated to further increase the degree of improvement of Fc.gamma.RIIb-binding activity; however, in reality, the Fc.gamma.RIIb-binding activity of the variant containing a combination of these alterations was decreased to 0.47 fold compared with that of IgG1. This result is an effect that could not have been predicted from the respective alterations.

[0257] Similarly, into IL6R-G1d-v1 (SEQ ID NO: 21) produced by introducing into IL6R-G1d the alteration produced by substituting Pro at position 238 (EU numbering) with Asp, the substitutions of Ser at position 267 (EU numbering) with Glu and of Leu at position 328 (EU numbering) with Phe as described in Example 2 which improve Fc.gamma.RIIb-binding activity were introduced, and the IL6R-G1d-v5 variant (SEQ ID NO: 26) was prepared according to the method of Reference Example 1. The obtained antibody having the amino acid sequence derived from IL6R-G1d-v5 as the antibody H chain has been named IgG1-v5. The Fc.gamma.RIIb-binding activities of IgG1, IgG1-v1, IgG1-v3, and IgG1-v5 were evaluated according to the method of Reference Example 2, and those results are shown in Table 5.

[0258] S267E/L328F which had an enhancing effect on Fc.gamma.RIIb in Example 2 was introduced into the P238D variant, and its Fc.gamma.RIIb-binding activities before and after introducing this alteration were evaluated. The results are shown in Table 5.

TABLE-US-00005 TABLE 5 Relative KD for KD for Fc.gamma.RIIb (KD of Fc.gamma.RIIb IgG1/KD Variant Alteration (mol/L) of each variant) IgG1 -- 5.30E-06 1 IgG1-v1 Substitution of Pro at position 238 1.10E-06 4.8 (EU numbering) with Asp IgG1-v3 Substitution of Ser at position 267 1.30E-08 408 (EU numbering) with Glu and substitution of Leu at position 328 (EU numbering) with Phe IgG1-v5 Substitution of Pro at position 238 4.50E-07 12 (EU numbering) with Asp, substitution of Ser at position 267 (EU numbering) with Glu, and substitution of Leu at position 328 (EU numbering) with Phe

[0259] From the results of Table 5, since S267E/L328F improves the Fc.gamma.RIIb-binding activity by 408 fold compared with IgG1, combining it with P238D which similarly improves the Fc.gamma.RIIb-binding activity by 4.8 fold as compared with IgG1 was anticipated to further increase the degree of improvement of Fc.gamma.RIIb-binding activity; however, in reality, in a similar manner to the former example, the Fc.gamma.RIIb-binding activity of the variant containing a combination of these alterations was improved only 12 fold or so as compared with that of IgG1. This result is also an effect that could not have been predicted from the effects of the respective alterations.

[0260] These results showed that while the substitution of Pro at position 238 (EU numbering) with Asp alone improves Fc.gamma.RIIb-binding activity, the effect is not exhibited when it is combined with other alterations that improve the Fc.gamma.RIIb-binding activity. A reason for this may be that the structure at the interacting interface between Fc and Fc.gamma.R is changed by introducing the substitution of Pro at position 238 (EU numbering) with Asp and the effects of alterations observed in the naturally-occurring antibody are no longer reflected in the results. Accordingly, it was considered to be extremely difficult to create an Fc with excellent selectivity for Fc.gamma.RIIb using an Fc comprising substitution of Pro at position 238 (EU numbering) with Asp as a template, since the information on effects of alterations obtained with naturally-occurring antibodies could not be applied.

Example 4

Comprehensive Analysis of Fc.gamma.RIIb Binding of Variants Introduced with an Alteration at the Hinge Portion in Addition to the P238D Alteration

[0261] As shown in Example 3, in an Fc produced by substituting Pro at position 238 (EU numbering) with Asp in a naturally-occurring human IgG1, an anticipated combinatorial effect could not be obtained even by combining it with another alteration predicted to further increase Fc.gamma.RIIb binding. Therefore, based on the altered Fc produced by substituting Pro at position 238

[0262] (EU numbering) with Asp, examination was carried out by comprehensively introducing alterations into the Fc to find variants that further enhance Fc.gamma.RIIb binding. For the antibody H chains, IL6R-F11 (SEQ ID NO: 27) was produced by introducing an alteration of substituting Met at position 252 (EU numbering) with Tyr and an alteration of substituting Asn at position 434 (EU numbering) with Tyr into IL6R-G1d (SEQ ID NO: 20), and IL6R-F652 (SEQ ID NO: 28) was prepared by introducing an additional alteration of substituting Pro at position 238 (EU numbering) with Asp. Expression plasmids containing an antibody H chain sequence were prepared for each of the antibody H chain sequences produced by substituting the region near the residue at position 238 (EU numbering) (positions 234 to 237, and 239 (EU numbering)) in IL6R-F652 each with 18 amino acids excluding the original amino acids and Cys. IL6R-L (SEQ ID NO: 22) was utilized as a common antibody L chain for all of the antibodies. These variants were expressed, purified, and expressed by the method of Reference Example 1. These Fc variants are called PD variants. Interactions of each PD variant with Fc.gamma.RIIa type R and Fc.gamma.RIIb were comprehensively evaluated by the method of Reference Example 2.

[0263] With regard to the results of analyzing the interaction with the respective Fc.gamma.Rs, a figure was produced according to the following method. The value obtained by dividing the value for the amount of binding of each PD variant to each Fc.gamma.R by the value for the amount of Fc.gamma.R binding of the pre-altered antibody which is used as the control (IL6R-F652/IL6R-L, which has an alteration of substituting Pro at position 238 (EU numbering) with Asp and then multiplying the result by 100, was used as the relative binding activity value of each PD variant to each Fc.gamma.R. The horizontal axis shows relative values of the Fc.gamma.RIIb-binding activity of each PD variant, and the vertical axis shows relative values of the Fc.gamma.RIIa type R-binding activity values of each PD variant (FIG. 6).

[0264] As a result, eleven types of alterations were found to have the effects of enhancing Fc.gamma.RIIb binding and maintaining or enhancing Fc.gamma.RIIa type R-binding in comparison with the antibody before introducing alterations. The activities of these eleven variants to bind Fc.gamma.RIIb and Fc.gamma.RIIa R are summarized in Table 6. In the table, SEQ ID NO refers to the SEQ ID NO of the H chain of the evaluated variant, and alteration refers to the alteration introduced into IL6R-F11 (SEQ ID NO: 27).

[0265] FIG. 7 shows relative values for the Fc.gamma.RIIb-binding activity obtained by additionally introducing these eleven alterations into a variant carrying the P238D alteration, and relative values for the Fc.gamma.RIIb-binding activity obtained by introducing these alterations into an Fc that does not contain the P238D alteration in Example 1. These eleven alterations enhanced the amount of Fc.gamma.RIIb binding compared with before introduction when they were further introduced into the P238D variant, but on the contrary, the effect of lowering Fc.gamma.RIIb binding was observed for eight of those alterations except G237F, G237W, and S239D, when they were introduced into the variant that does not contain P238D (GpH7-B3/GpL16-k0) used in Example 1. Example 3 and these results showed that from the effects of introducing alterations into a naturally-occurring IgG1, it is difficult to predict the effects of introducing the same alterations into the variant containing an Fc with the P238D alteration. In other words, it would not have been possible to discover these eight alterations identified this time without this investigation.

[0266] The results of measuring KD values of the variants indicated in Table 6 for Fc.gamma.RIa, Fc.gamma.RIIaR, Fc.gamma.RIIaH, Fc.gamma.RIIb, and Fc.gamma.RIIIaV by the method of Reference Example 2 are summarized in Table 7. In the table, SEQ ID NO refers to the SEQ ID NO of the H chain of the evaluated variant, and alteration refers to the alteration introduced into IL6R-F11 (SEQ ID NO: 27). The template used for producing IL6R-F11, IL6R-G1d/IL6R-L, is indicated with an asterisk (*). Furthermore, KD(IIaR)/KD(IIb) and KD(IIaH)/KD(IIb) in the table respectively show the value obtained by dividing the KD value of each variant for Fc.gamma.RIIaR by the KD value of each variant for Fc.gamma.RIIb, and the value obtained by dividing the KD value of each variant for Fc.gamma.RIIaH by the KD value of each variant for Fc.gamma.RIIb. KD(IIb) of the parent polypeptide/KD(IIb) of the altered polypeptide refers to a value obtained by dividing the KD value of the parent polypeptide for Fc.gamma.RIIb by the KD value of each variant for Fc.gamma.RIIb. In addition, Table 7 shows KD values for the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of each variant/KD values for the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of the parent polypeptide. Here, parent polypeptide refers to a variant which has IL6R-F11 (SEQ ID NO: 27) as the H chain. It was determined that due to weak binding of Fc.gamma.R to IgG, it was impossible to accurately analyze by kinetic analysis, and thus the gray-filled cells in Table 7 show values calculated by using Equation 2 of Reference Example 2.

KD=CR.sub.max/(R.sub.eq-RI)-C [Equation 2]

[0267] Table 7 shows that all variants improved their affinity for Fc.gamma.RIIb in comparison with IL6R-F11, and the range of improvement was 1.9 fold to 5.0 fold. The ratio of KD value of each variant for Fc.gamma.RIIaR/KD value of each variant for Fc.gamma.RIIb, and the ratio of KD value of each variant for Fc.gamma.RIIaH/KD value of each variant for Fc.gamma.RIIb represent an Fc.gamma.RIIb-binding activity relative to the Fc.gamma.RIIaR-binding activity and Fc.gamma.RIIaH-binding activity, respectively. That is, these values show the degree of binding selectivity of each variant for Fc.gamma.RIIb, and a larger value indicates a higher binding selectivity for Fc.gamma.RIIb. For the parent polypeptide IL6R-F11/IL6R-L, the ratio of KD value for Fc.gamma.RIIaR/KD value for Fc.gamma.RIIb and the ratio of KD value for Fc.gamma.RIIaH/KD value for Fc.gamma.RIIb are both 0.7, and accordingly all variants in Table 7 showed improvement of binding selectivity for Fc.gamma.RIIb in comparison with the parent polypeptide. When the KD value for the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of a variant/KD value for the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of the parent polypeptide is 1 or more, this means that the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of a variant has equivalent or reduced binding compared with the binding by the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of the parent polypeptide. Since this value was 0.7 to 5.0 for the variants obtained this time, one may say that binding by the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of the variants obtained this time was nearly the same or decreased in comparison with the parent polypeptide. These results showed that compared with the parent polypeptide, the variants obtained this time have maintained or decreased binding activities to Fc.gamma.RIIa type R and type H, and improved selectivity for Fc.gamma.RIIb. Furthermore, compared with IL6R-F11, all variants had lower affinity to Fc.gamma.RIa and Fc.gamma.RIIIaV.

X-Ray Crystallographic Analysis of a Complex Formed Between an Fc Containing P238D and an Extracellular Region of Fc.gamma.RIIb

[0268] As indicated earlier in Example 3, even though an alteration that improves Fc.gamma.RIIb-binding activity or selectivity for Fc.gamma.RIIb is introduced into an Fc containing P238D, the Fc.gamma.RIIb-binding activity was found to decrease, and the reason for this may be that the structure at the interacting interface between Fc and Fc.gamma.RIIb is changed due to introduction of P238D. Therefore, to pursue the reason for this phenomena, the three-dimensional structure of the complex formed between an IgG1 Fc containing the P238D mutation (hereinafter, Fc(P238D)) and the extracellular region of Fc.gamma.RIIb was elucidated by X-ray crystallographic analysis, and the three-dimensional structure and binding mode were compared to those of the complex formed between the Fc of a naturally-occurring IgG1 (hereinafter, Fc(WT)) and the extracellular region of Fc.gamma.RIIb. Many reports have been made on the three-dimensional structure of a complex formed between an Fc and an Fc.gamma.R extracellular region; and the three-dimensional structures of the Fc(WT)/Fc.gamma.RIIIb extracellular region complex (Nature, 2000, 400: 267-273; J. Biol. Chem. 2011, 276: 16469-16477), the Fc(WT)/Fc.gamma.RIIIa extracellular region complex (Proc. Natl. Acad. Sci. USA, 2011, 108: 12669-126674), and the Fc(WT)/Fc.gamma.RIIa extracellular region complex (J. Immunol. 2011, 187: 3208-3217) have been analyzed. While the three-dimensional structure of the Fc(WT)/Fc.gamma.RIIb extracellular region complex has not been analyzed, the three-dimensional structure of a complex formed with Fc(WT) is known for Fc.gamma.RIIa, and the extracellular regions of Fc.gamma.RIIa and Fc.gamma.RIIb match 93% in amino acid sequence and have very high homology. Thus, the three-dimensional structure of the Fc(WT)/Fc.gamma.RIIb extracellular region complex was predicted by modeling using the crystal structure of the Fc(WT)/Fc.gamma.RIIa extracellular region complex.

[0269] The three-dimensional structure of the Fc(P238D)/Fc.gamma.RIIb extracellular region complex was determined by X-ray crystallographic analysis at 2.6 .ANG. resolution. The structure obtained as a result of this analysis is shown in FIG. 8. The Fc.gamma.RIIb extracellular region is bound between two Fc CH2 domains, and this is similar to the three-dimensional structures of complexes formed between Fc(WT) and the respective extracellular region of Fc.gamma.RIIIa, Fc.gamma.RIIIb, or Fc.gamma.RIIa analyzed so far.

[0270] Next, for detailed comparison, the crystal structure of the Fc(P238D)/Fc.gamma.RIIb extracellular region complex and the model structure of the Fc(WT)/Fc.gamma.RIIb extracellular region complex were superimposed by the least squares fitting based on the C.alpha. atom pair distances with respect to the Fc.gamma.RIIb extracellular region and the Fc CH2 domain A (FIG. 9). In that case, the degree of overlap between Fc CH2 domains B was not satisfactory, and conformational differences were found in this portion. Furthermore, using the crystal structure of the Fc(P238D)/Fc.gamma.RIIb extracellular region complex and the model structure of the Fc(WT)/Fc.gamma.RIIb extracellular region complex, pairs of atoms that have a distance of 3.7 .ANG. or less between the Fc.gamma.RIIb extracellular region and Fc CH2 domain B were extracted and compared in order to observe the differences in interatomic interactions between Fc.gamma.RIIb and Fc CH2 domain B in Fc(WT) and Fc(P238D). As shown in Table 8, the interatomic interactions between Fc CH2 domain B and Fc.gamma.RIIb in Fc(P238D) and Fc(WT) do not match.

[0271] Furthermore, the X-ray crystal structure of the Fc(P238D)/Fc.gamma.RIIb extracellular region complex and the model structure of the Fc(WT)/Fc.gamma.RIIb extracellular region complex were superimposed by the least squares fitting based on the C.alpha. atom pair distances with respect to the only Fc CH2 domain A or the only Fc CH2 domain B, and the detailed structures near P238D were compared. The location of the amino acid residue at position 238 (EU numbering), which is mutation introduction position, is changed between Fc(P238D) and Fc(WT), one can see that along with this change, the nearby loop structure continuing from this hinge region is changed between Fc(P238D) and Fc(WT) (FIG. 10). Originally in Fc(WT), Pro at position 238 (EU numbering) is present on the inner side of the protein, and forms a hydrophobic core with the surrounding residues. However, when this residue is changed to a charged and very hydrophilic Asp, the presence in the same hydrophobic core would cause energetical disadvantage in terms of desolvation. Therefore, in Fc(P238D), to cancel this energetically disadvantageous situation, the amino acid residue at position 238 (EU numbering) changes its orientation to face the solvent side, and this may have caused this change in the nearby loop structure. Furthermore, since this loop continues from the hinge region crosslinked by an S--S bond, its structural change will not be limited to a local change, and will affect the relative positioning of the FcCH2 domain A and domain B. As a result, the interatomic interactions between Fc.gamma.RIIb and Fc CH2 domain B have been changed. Therefore, predicted effects could not be observed when alterations that improve selectivity and binding activity towards Fc.gamma.RIIb in a naturally-occurring IgG were combined with an Fc containing the P238D alteration.

[0272] Furthermore, as a result of structural changes due to introduction of P238D in Fc CH2 domain A, a hydrogen bond has been found between the main chain of Gly at adjacent position 237 (EU numbering) and Tyr at position 160 in Fc.gamma.RIIb (FIG. 11). The residue in Fc.gamma.RIIa that corresponds to this Tyr 160 is Phe; and when the binding is to Fc.gamma.RIIa, this hydrogen bond is not formed. The amino acid at position 160 is one of the few differences between Fc.gamma.RIIa and Fc.gamma.RIIb at the interface of interaction with Fc, the presence of this hydrogen bond which is specific to Fc.gamma.RIIb is presumed to have led to improvement of Fc.gamma.RIIb-binding activity and decrease of Fc.gamma.RIIa-binding activity in Fc(P238D), and improvement of its selectivity. Furthermore, in Fc CH2 domain B, an electrostatic interaction is observed between Asp at position 270 (EU numbering) and Arg at position 131 in Fc.gamma.RIIb (FIG. 12). In Fc.gamma.RIIa type H, which is one of the allotypes of Fc.gamma.RIIa, the corresponding residue is His, and therefore cannot form this electrostatic interaction. This can explain why the Fc(P238D)-binding activity is lowered in Fc.gamma.RIIa type H compared with Fc.gamma.RIIa type R. Observations based on such results of X-ray crystallographic analysis showed that the change of the loop structure beside P238D due to P238D introduction and the accompanying change in the relative domain positioning causes formation of new interactions not found in the naturally-occurring IgG, and this led to a selective binding profile of P238D variants for Fc.gamma.RIIb.

[Expression and Purification of Fc(P238D)]

[0273] An Fc containing the P238D alteration was prepared as follows. First, Cys at position 220 (EU numbering) of hIL6R-IgG1-v1 (SEQ ID NO: 21) was substituted with Ser. Then, genetic sequence of Fc(P238D) from Glu at position 236 (EU numbering) to its C terminal was cloned by PCR. Using this cloned genetic sequence, production of expression vectors, and expression and purification of Fc(P238D) were carried out according to the method of Reference Example 1. Cys at position 220 (EU numbering) forms a disulfide bond with Cys of the L chain in general IgG1. The L chain is not co-expressed when Fc alone is prepared, and therefore, this residue was substituted with Ser to avoid formation of unnecessary disulfide bonds.

[Expression and Purification of the Fc.gamma.RIIb Extracellular Region]

[0274] This was prepared according to the method of Reference Example 2.

[Purification of the Fc(P238D)/Fc.gamma.RIIb Extracellular Region Complex]

[0275] To 2 mg of the Fc.gamma.RIIb extracellular region sample obtained for crystallization, 0.29 mg of Endo F1 (Protein Science 1996, 5: 2617-2622) expressed and purified from Escherichia coli as a glutathione S-transferase fusion protein was added. This was allowed to remain at room temperature for three days in 0.1 M Bis-Tris buffer at pH 6.5, and the N-linked oligosaccharide was cleaved, leaving N-acetylglucosamine directly bound to Asn. Next, this Fc.gamma.RIIb extracellular domain sample subjected to carbohydrate cleavage treatment was concentrated by ultrafiltration with 5000 MWCO, and purified by gel filtration chromatography (Superdex200 10/300) using a column equilibrated in 20 mM HEPS at pH 7.5 containing 0.05 M NaCl. Furthermore, to the obtained carbohydrate-cleaved Fc.gamma.RIIb extracellular region fraction, Fc(P238D) was added so that the molar ratio of the Fc.gamma.RIIb extracellular region would be present in slight excess, and after concentration by ultrafiltration with 10,000 MWCO, a sample of the Fc(P238D)/Fc.gamma.RIIb extracellular region complex was obtained through purification by gel filtration chromatography (Superdex200 10/300) using a column equilibrated in 20 mM HEPS at pH 7.5 containing 0.05 M NaCl.

[Crystallization of the Fc(P238D)/Fc.gamma.RIIb Extracellular Region Complex]

[0276] A sample of the Fc(P238D)/Fc.gamma.RIIb extracellular region complex was concentrated to approximately 10 mg/mL by ultrafiltration with 10,000 MWCO, and crystallization was carried out by the sitting drop vapor diffusion method. Hydra II Plus One (MATRIX) was used for crystallization; and for a reservoir solution containing 100 mM Bis-Tris pH 6.5, 17% PEG3350, 0.2 M ammonium acetate, and 2.7% (w/v) D-Galactose, a crystallization drop was produced by mixing at a ratio of reservoir solution:crystallization sample=0.2 .mu.L:0.2 .mu.L, and after sealing, this was allowed to remain at 20.degree. C., and thin plate-like crystals were successfully obtained.

[Measurement of X-Ray Diffraction Data from an Fc(P238D)/Fc.gamma.RIIb Extracellular Region Complex Crystal]

[0277] One of the obtained single crystals of the Fc(P238D)/Fc.gamma.RIIb extracellular region complex was soaked into a solution of 100 mM Bis-Tris pH 6.5, 20% PEG3350, ammonium acetate, 2.7% (w/v) D-Galactose, 22.5% (v/v) ethylene glycol. The crystal was fished out of the solution using a pin with attached tiny nylon loop, and frozen in liquid nitrogen; and then X-ray diffraction data was measured at synchrotron radiation facility Photon Factory BL-1A in High Energy Accelerator Research Organization. During the measurement, the crystal was constantly placed in a nitrogen stream at -178.degree. C. to maintain in a frozen state, and a total of 225 X ray diffraction images were collected using Quantum 270 CCD detector (ADSC) attached to a beam line with rotating the crystal 0.8.degree. at a time. Determination of cell parameters, indexing of diffraction spots, and diffraction data processing from the obtained diffraction images were performed using the Xia2 program (CCP4 Software Suite), XDS Package (Walfgang Kabsch) and Scala (CCP4 Software Suite); and finally, diffraction intensity data up to 2.46 .ANG. resolution was obtained. The crystal belongs to the space group P2.sub.1, and has the following cell parameters; a=48.85 .ANG., b=76.01 .ANG., c=115.09 .ANG., .alpha.=90.degree., .beta.=100.70.degree., .gamma.=90.degree..

[X Ray Crystallographic Analysis of the Fc(P238D)/Fc.gamma.RIIb Extracellular Region Complex]

[0278] Crystal structure of the Fc(P238D)/Fc.gamma.RIIb extracellular region complex was determined by the molecular replacement method using the program Phaser (CCP4 Software Suite). From the size of the obtained crystal lattice and the molecular weight of the Fc(P238D)/Fc.gamma.RIIb extracellular region complex, the number of complexes in the asymmetric unit was predicted to be one. From the structural coordinates of PDB code: 3 SGJ which is the crystal structure of the Fc(WT)/Fc.gamma.RIIIa extracellular region complex, the amino acid residue portions of the A chain positions 239-340 and the B chain positions 239-340 were taken out as separate coordinates, and they were used respectively as models for searching the Fc CH2 domains. The amino acid residue portions of the A chain positions 341-444 and the B chain positions 341-443 were taken out as a single set of coordinates from the same structural coordinates of PDB code: 3SGJ; and this was used as a model for searching the Fc CH3 domains. Finally, from the structural coordinates of PDB code: 2FCB which is a crystal structure of the Fc.gamma.RIIb extracellular region, the amino acid residue portions of the A chain positions 6-178 was taken out and used as a model for searching the Fc.gamma.RIIb extracellular region. The orientation and position of each search model in the crystal lattice were determined in the order of Fc CH3 domain, Fc.gamma.RIIb extracellular region, and Fc CH2 domain, based on the rotation function and translation function to obtain the initial model for the crystal structure of the Fc(P238D)/Fc.gamma.RIIb extracellular region complex. When rigid body refinement which moves the two Fc CH2 domains, the two Fc CH3 domains, and the Fc.gamma.RIIb extracellular region was performed on the obtained initial model, the crystallographic reliability factor, R value became 40.4%, and the Free R value became 41.9% to diffraction intensity data from 25 .ANG. to 3.0 .ANG. at this point. Furthermore, structural refinement using the program Refmac5 (CCP4 Software Suite), and revision of the model to observe the electron density maps whose coefficient have 2Fo-Fc or Fo-Fc, which are calculated based on the experimentally determined structural factor Fo, the calculated structural factor Fc and the calculated phase using the model, was carried out by the Coot program (Paul Emsley), and model refinement was carried out by repeating these steps. Finally, as a result of incorporation of water molecules into the model based on the electron density maps which use 2Fo-Fc or Fo-Fc as the coefficient, and the following refinement, the crystallographic reliability factor, R values and the Free R value of the model containing 4846 non-hydrogen atoms became 23.7% and 27.6% to 24291 diffraction intensity data from 25 .ANG. to 2.6 .ANG. resolution, respectively.

[Production of a Model Structure of the Fc(WT)/Fc.gamma.RIIb Extracellular Region Complex]

[0279] Based on the structural coordinates of PDB code: 3RY6 which is a crystal structure of the Fc(WT)/Fc.gamma.RIIa extracellular region complex, the Build Mutants function of the Discovery Studio 3.1 program (Accelrys) was used to introduce mutations to match the amino acid sequence of Fc.gamma.RIIb into Fc.gamma.RIIa in this structural coordinates. In that case, the Optimization Level was set to High, Cut Radius was set to 4.5, five models were generated, and the one with the best energy score from among them was employed as the model structure for the Fc(WT)/Fc.gamma.RIIb extracellular region complex.

Example 6

Analysis of Fc.gamma.R Binding of Fc Variants Whose Alteration Sites were Determined Based on Crystal Structures

[0280] Based on the results of X-ray crystallographic analysis on the complex formed between Fc(P238D) and the Fc.gamma.RIIb extracellular region obtained in Example 5, comprehensive alterations were introduced into sites on the altered Fc having substitution of Pro at position 238 (EU numbering) with Asp that were predicted to affect interaction with Fc.gamma.RIIb, (residues of positions 233, 240, 241, 263, 265, 266, 267, 268, 271, 273, 295, 296, 298, 300, 323, 325, 326, 327, 328, 330, 332, and 334 (EU numbering)) and variants with a combination of alterations that enhance Fc.gamma.RIIb binding were examined

[0281] IL6R-B3 (SEQ ID NO: 40) was produced by introducing into IL6R-G1d (SEQ ID NO: 20) produced in Example 2, the alteration produced by substituting Lys at position 439 (EU numbering) with Glu. Next, IL6R-BF648 (SEQ ID NO: 41) was produced by introducing into IL6R-B3, the alteration produced by substituting Pro at position 238 (EU numbering) with Asp. IL6R-L (SEQ ID NO: 22) was utilized as the common antibody L chain for all of the antibodies. These antibody variants were expressed and purified according to the method of Reference Example 1, and binding to each of the Fc.gamma.Rs (Fc.gamma.RIa, Fc.gamma.RIIa type H, Fc.gamma.RIIa type R, Fc.gamma.RIIb, and Fc.gamma.RIIIa type V) was comprehensively evaluated by the method of Reference Example 2.

[0282] A figure was produced according to the following method for the results of analyzing the interactions with the respective Fc.gamma.Rs. The value for the amount of binding of each variant to each Fc.gamma.R was divided by the value for the amount of binding of the pre-altered control antibody (IL6R-BF648/IL6R-L with Pro at position 238 (EU numbering) substituted with Asp) to each Fc.gamma.R, and the obtained was then multiplied by 100 and used as the relative binding activity value of each variant to each Fc.gamma.R. The horizontal axis shows the relative binding activity value of each variant to Fc.gamma.RIIb, and the vertical axis shows the relative binding activity value of each variant to Fc.gamma.RIIa type R (FIG. 13).

[0283] As shown in FIG. 13, the results show that of all the alterations, 24 types of alterations were found to have an effect of maintaining or enhancing Fc.gamma.RIIb binding in comparison with the pre-altered antibody. The binding of these variants to each of the Fc.gamma.Rs are shown in Table 9. In the table, SEQ ID NO refers to the SEQ ID NO of the H chain of the evaluated variant, and alteration refers to the alteration introduced into IL6R-B3 (SEQ ID NO: 40). The template used for producing IL6R-B3, IL6R-G1d/IL6R-L, is indicated with an asterisk (*).

[0284] The results of measuring KD values of the variants shown in Table 9 for Fc.gamma.RIa, Fc.gamma.RIIaR, Fc.gamma.RIIaH, Fc.gamma.RIIb, and Fc.gamma.RIIIa type V by the method of Reference Example 2 are summarized in Table 10. In the table, SEQ ID NO refers to the SEQ ID NO of the H chain of the evaluated variant, and alteration refers to the alteration introduced into IL6R-B3 (SEQ ID NO: 40). The template used for producing IL6R-B3, IL6R-G1d/IL6R-L, is indicated with an asterisk (*). Furthermore, KD(IIaR)/KD(IIb) and KD(IIaH)/KD(IIb) in the table respectively represent the value obtained by dividing the KD value of each variant for Fc.gamma.RIIaR by the KD value of each variant for Fc.gamma.RIIb, and the value obtained by dividing the KD value of each variant for Fc.gamma.RIIaH by the KD value of each variant for Fc.gamma.RIIb. KD(IIb) of the parent polypeptide/KD(IIb) of the altered polypeptide refers to the value obtained by dividing the KD value of the parent polypeptide for Fc.gamma.RIIb by the KD value of each variant for Fc.gamma.RIIb. In addition, the KD value for the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of each variant/KD value for the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of the parent polypeptide are shown in Table 10. Here, parent polypeptide refers to the variant which has IL6R-B3 (SEQ ID NO: 40) as the H chain. It was determined that due to weak binding of Fc.gamma.R to IgG, it was impossible to accurately analyze by kinetic analysis, and thus the gray-filled cells in Table 10 show values calculated by using Equation 2 of Reference Example 2.

KD=CR.sub.max/(R.sub.eq-RI)-C [Equation 2]

[0285] Table 10 shows that in comparison with IL6R-B3, all variants showed improvement of affinity for Fc.gamma.RIIb, and the range of improvement was 2.1 fold to 9.7 fold. The ratio of KD value of each variant for Fc.gamma.RIIaR/KD value of each variant for Fc.gamma.RIIb, and the ratio of KD value of each variant for Fc.gamma.RIIaH/KD value of each variant for Fc.gamma.RIIb represent an Fc.gamma.RIIb-binding activity relative to the Fc.gamma.RIIaR-binding activity and Fc.gamma.RIIaH-binding activity, respectively. That is, these values show the degree of binding selectivity of each variant for Fc.gamma.RIIb, and a greater value indicates a higher binding selectivity for Fc.gamma.RIIb. Since the ratio of KD value for Fc.gamma.RIIaR/KD value for Fc.gamma.RIIb, and the ratio of KD value for Fc.gamma.RIIaH/KD value for Fc.gamma.RIIb in the parent polypeptide IL6R-B3/IL6R-L were 0.3 and 0.2, respectively, all variants in Table 10 showed improvement of binding selectivity for Fc.gamma.RIIb in comparison with the parent polypeptide. When the KD value for the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of a variant/KD value for the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of the parent polypeptide is 1 or more, this means that the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of a variant has equivalent or decreased binding compared with the binding by the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of the parent polypeptide. Since this value was 4.6 to 34.0 for the variants obtained this time, one may say that in comparison with the parent polypeptide, the variants obtained this time had reduced binding by the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities. These results showed that compared with the parent polypeptide, the variants obtained this time have maintained or decreased Fc.gamma.RIIa type R- and type H-binding activities, enhanced Fc.gamma.RIIb-binding activity, and improved selectivity for Fc.gamma.RIIb. Furthermore, compared with IL6R-B3, all variants had lower affinity to Fc.gamma.RIa and Fc.gamma.RIIIaV.

[0286] With regard to the promising variants among the obtained combination variants, the factors leading to their effects were studied using the crystal structure. FIG. 14 shows the crystal structure of the Fc(P238D)/Fc.gamma.RIIb extracellular region complex. In this figure, the H chain positioned on the left side is Fc Chain A, and the H chain positioned on the right side is Fc Chain B. Here, one can see that the site at position 233 (EU numbering) in Fc Chain A is located near Lys at position 113 (EU numbering) of Fc.gamma.RIIb. However, in this crystal structure, the E233 side chain is in a condition of considerably high mobility, and its electron density is not well observed. Therefore, the alteration produced by substituting Glu at position 233 (EU numbering) with Asp leads to decrease in the degree of freedom of the side chain since the side chain becomes one carbon shorter. As a result, the entropy loss when forming an interaction with Lys at position 113 (EU numbering) of Fc.gamma.RIIb may be decreased, and consequently this is speculated to contribute to improvement of binding free energy.

[0287] Similarly, FIG. 15 shows the environment near the site at position 330 (EU numbering) in the structure of the Fc(P238D)/Fc.gamma.RIIb extracellular region complex. This figure shows that the environment around the site at position 330 (EU numbering) of Fc Chain A of Fc (P238D) is a hydrophilic environment composed of Ser at position 85, Glu at position 86, Lys at position 163, and such (EU numbering) of Fc.gamma.RIIb. Therefore, the alteration produced by substituting Ala at position 330 (EU numbering) with Lys or Arg is speculated to contribute to strengthening the interaction with Ser at position 85 (EU numbering) or Glu at position 86 (EU numbering) in Fc.gamma.RIIb.

[0288] FIG. 16 depicts the structures of Pro at position 271 (EU numbering) of Fc Chain B after superimposing the crystal structures of the Fc(P238D)/Fc.gamma.RIIb extracellular region complex and the Fc(WT)/Fc.gamma.RIIIa extracellular region complex by the least squares fitting based on the C.alpha. atom pair distances with respect to Fc Chain B. These two structures match well, but have different three-dimensional structures of Pro at position 271 (EU numbering). When the weak electron density around this area in the crystal structure of the Fc(P238D)/Fc.gamma.RIIb extracellular region complex is also taken into consideration, it is suggested that there is possibility that Pro at position 271 (EU numbering) in Fc(P238D)/Fc.gamma.RIIb causes a large strain on the structure, thus disturbing the loop structure to attain an optimal structure. Therefore, the alteration produced by substituting Pro at position 271 (EU numbering) with Gly gives flexibility to this loop structure, and is speculated to contribute to enhancement of binding by reducing the energetic barrier when allowing an optimum structure to form during interaction with Fc.gamma.RIIb.

Example 7

Examination of the Combinatorial Effect of Alterations that Enhance Fc.gamma.RIIb Binding When Combined with P238D

[0289] Of the alterations obtained in Examples 4 and 6, those that enhanced Fc.gamma.RIIb binding or maintained Fc.gamma.RIIb binding and showed effects of suppressing binding to other Fc.gamma.Rs were combined with each other, and their effects were examined

[0290] Particularly good alterations were selected from Tables 6 and 9, and they were combined and introduced into the antibody H chain IL6R-BF648 in a similar manner to the method of Example 6. IL6R-L was utilized as the common antibody L chain for all of the antibodies, the antibodies were expressed and purified according to the method of Reference Example 1, and binding to each of the Fc.gamma.Rs (Fc.gamma.RIa, Fc.gamma.RIIa H type, Fc.gamma.RIIa R type, Fc.gamma.RIIb, and Fc.gamma.RIIIa V type) was comprehensively evaluated by the method of Reference Example 2.

[0291] Relative binding activities were calculated for the results of analyzing interactions with the respective Fc.gamma.Rs according to the following method. The value for the amount of binding of each variant to each Fc.gamma.R was divided by the value for the amount of binding of the pre-altered control antibody (IL6R-BF648/IL6R-L with substitution of Pro at position 238 (EU numbering) with Asp to each Fc.gamma.R, and multiplied by 100; and then the value was used as the relative binding activity value of each variant to each Fc.gamma.R. The horizontal axis shows the relative binding activity value of each variant to Fc.gamma.RIIb, and the vertical axis shows the relative binding activity value of each variant to Fc.gamma.RIIa type R (Table 11).

[0292] In the table, SEQ ID NO refers to the SEQ ID NO of the H chain of the evaluated variant, and alteration refers to the alteration introduced into IL6R-B3 (SEQ ID NO: 40). The template used for producing IL6R-B3, IL6R-G1d/IL6R-L, is indicated with an asterisk (*).

[0293] The results of measuring KD values of the variants shown in Table 11 for Fc.gamma.RIa, Fc.gamma.RIIaR, Fc.gamma.RIIaH, Fc.gamma.RIIb, and Fc.gamma.RIIIa type V by the method of Reference Example 2 are summarized in Table 12. In the table, SEQ ID NO refers to the SEQ ID NO of the H chain of the evaluated variant, and alteration refers to the alteration introduced into IL6R-B3 (SEQ ID NO: 40). The template used for producing IL6R-B3, IL6R-G1d/IL6R-L, is indicated with an asterisk (*). Furthermore, KD(IIaR)/KD(IIb) and KD(IIaH)/KD(IIb) in the table respectively represent the value obtained by dividing the KD value of each variant for Fc.gamma.RIIaR by the KD value of each variant for Fc.gamma.RIIb, and the value obtained by dividing the KD value of each variant for Fc.gamma.RIIaH by the KD value of each variant for Fc.gamma.RIIb. KD(IIb) of the parent polypeptide/KD(IIb) of the altered polypeptide refers to the value obtained by dividing the KD value of the parent polypeptide for Fc.gamma.RIIb by the KD value of each variant for Fc.gamma.RIIb. In addition, the KD value for the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of each variant/KD value for the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of the parent polypeptide are shown in Table 12. Here, parent polypeptide refers to the variant which has IL6R-B3 (SEQ ID NO: 40) as the H chain. It was determined that due to weak binding of Fc.gamma.R to IgG, it was impossible to accurately analyze by kinetic analysis, and thus the gray-filled cells in Table 12 show values calculated by using Equation 2 of Reference Example 2.

KD=CR.sub.max/(R.sub.eq-RI)-C [Equation 2]

[0294] Table 12 shows that in comparison with IL6R-B3, all variants showed improvement of affinity for Fc.gamma.RIIb, and the range of improvement was 3.0 fold to 99.0 fold. The ratio of KD value of each variant for Fc.gamma.RIIaR/KD value of each variant for Fc.gamma.RIIb, and the ratio of KD value of each variant for Fc.gamma.RIIaH/KD value of each variant for Fc.gamma.RIIb represent an Fc.gamma.RIIb-binding activity relative to the Fc.gamma.RIIaR-binding activity and Fc.gamma.RIIaH-binding activity, respectively. That is, those values show the degree of binding selectivity of each variant for Fc.gamma.RIIb, and a greater value indicates a higher binding selectivity for Fc.gamma.RIIb. Since the ratio of KD value for Fc.gamma.RIIaR/KD value for Fc.gamma.RIIb, and the ratio of KD value for Fc.gamma.RIIaH/KD value for Fc.gamma.RIIb of the parent polypeptide IL6R-B3/IL6R-L were 0.3 and 0.2, respectively, all variants in Table 12 showed improvement of binding selectivity for Fc.gamma.RIIb in comparison with the parent polypeptide. When the KD value for the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of a variant/KD value for the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of the parent polypeptide is 1 or more, this means that the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of a variant has equivalent or decreased binding compared with the binding by the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of the parent polypeptide. Since this value was 0.7 to 29.9 for the variants obtained this time, one may say that binding by the stronger of the Fc.gamma.RIIaR- and Fc.gamma.RIIaH-binding activities of the variants obtained this time was nearly equivalent or decreased compared with that of the parent polypeptide. These results showed that compared with the parent polypeptide, the variants obtained this time have maintained or decreased Fc.gamma.RIIa type R- and type H-binding activities, enhanced Fc.gamma.RIIb-binding activity, and improved selectivity for Fc.gamma.RIIb. Furthermore, compared with IL6R-B3, all variants had lower affinity for Fc.gamma.RIa and Fc.gamma.RIIIaV.

Construction of Antibody Expression Vectors; and Expression and Purification of Antibodies

[0295] Synthesis of full-length genes encoding the nucleotide sequences of the H chain and L chain of the antibody variable regions was carried out by production methods known to those skilled in the art using Assemble PCR and such. Introduction of amino acid substitutions was carried out by methods known to those skilled in the art using PCR or such. The obtained plasmid fragment was inserted into an animal cell expression vector, and the H-chain expression vector and L-chain expression vector were produced. The nucleotide sequence of the obtained expression vector was determined by methods known to those skilled in the art. The produced plasmids were introduced transiently into the HEK293H cell line derived from human embryonic kidney cancer cells (Invitrogen) or into FreeStyle293 cells (Invitrogen) for antibody expression. The obtained culture supernatant was collected, and then passed through a 0.22 .mu.m MILLEX(R)-GV filter (Millipore), or through a 0.45 .mu.m MILLEX(R)-GV filter (Millipore) to obtain the culture supernatant. Antibodies were purified from the obtained culture supernatant by methods known to those skilled in the art using rProtein A Sepharose Fast Flow (GE Healthcare) or Protein G Sepharose 4 Fast Flow (GE Healthcare). For the concentration of the purified antibodies, their absorbance at 280 nm was measured using a spectrophotometer. From the obtained value, the extinction coefficient calculated by the methods such as PACE was used to calculate the antibody concentration (Protein Science 1995; 4: 2411-2423).

Method for Preparing Fc.gamma.R and Method for Analyzing the Interaction Between an Altered Antibody and Fc.gamma.R

[0296] Extracellular domains of Fc.gamma.Rs were prepared by the following method. First, a gene of the extracellular domain of Fc.gamma.R was synthesized by a method well known to those skilled in the art. At that time, the sequence of each Fc.gamma.R was produced based on the information registered at NCBI. Specifically, Fc.gamma.RI was produced based on the sequence of NCBI Accession No. NM.sub.--000566.3, Fc.gamma.RIIa was produced based on the sequence of NCBI Accession No. NM.sub.--001136219.1, Fc.gamma.RIIb was produced based on the sequence of NCBI Accession No. NM.sub.--004001.3, Fc.gamma.RIIIa was produced based on the sequence of NCBI Accession No. NM.sub.--001127593.1, and Fc.gamma.RIIIb was produced based on the sequence of NCBI Accession No. NM.sub.--000570.3, and a His tag was attached to the C terminus Furthermore, polymorphism is known for Fc.gamma.RIIa, Fc.gamma.RIIIa, and Fc.gamma.RIIIb, and the polymorphic sites were produced by referring to J. Exp. Med., 1990, 172: 19-25 for Fc.gamma.RIIa; J. Clin. Invest., 1997, 100 (5): 1059-1070 for Fc.gamma.RIIIa; and J. Clin. Invest., 1989, 84, 1688-1691 for Fc.gamma.RIIIb.

[0297] The obtained gene fragments were inserted into an animal cell expression vector, and expression vectors were produced. The produced expression vectors were introduced transiently into human embryonic kidney cancer cell line-derived FreeStyle293 cells (Invitrogen) to express the proteins of interest. Regarding Fc.gamma.RIIb used for crystallographic analysis, the protein of interest was expressed in the presence of Kifunensine at a final concentration of 10 .mu.g/mL, so that the sugar chain added to Fc.gamma.RIIb will be the high-mannose type. Cells were cultured, and after collection of the obtained culture supernatant, this was passed through a 0.22 .mu.m filter to obtain the culture supernatant. In principle, the obtained culture supernatants were purified in the following four steps. The steps carried out were, cation exchange column chromatography (SP Sepharose FF) in step 1, affinity column chromatography (HisTrap HP) for His tag in step 2, gel filtration column chromatography (Superdex200) in step 3, and aseptic chromatography in step 4. However, for Fc.gamma.RI, anion exchange column chromatography using Q sepharose FF was performed as step 1. The purified proteins were subjected to absorbance measurements at 280 nm using a spectrophotometer; and from the obtained values, the concentrations of the purified proteins were calculated using the absorption coefficient calculated using methods such as PACE (Protein Science 1995; 4: 2411-2423).

[0298] Analysis of interaction between each altered antibody and the Fc.gamma. receptor prepared as mentioned above was carried out using Biacore T100 (GE Healthcare), Biacore T200 (GE Healthcare), Biacore A100, and Biacore 4000. HBS-EP+ (GE Healthcare) was used as the running buffer, and the measurement temperature was set to 25.degree. C. Chips produced by immobilizing the antigen peptide, Protein A (Thermo Scientific), Protein A/G (Thermo Scientific), and Protein L (ACTIGEN or BioVision) by the amine coupling method to a Series S sensor Chip CMS (GE Healthcare) or Series S sensor Chip CM4 (GE Healthcare), or alternatively, chips produced by allowing preliminarily biotinylated antigen peptides to interact with and immobilize onto a Series S Sensor Chip SA (certified) (GE Healthcare) were used.

[0299] After capturing of antibodies of interest onto these sensor chips, an Fc.gamma. receptor diluted with the running buffer was allowed to interact, the amount bound to an antibody was measured, and the antibodies were compared. However, since the amount of Fc.gamma. receptor bound depends on the amount of the captured antibodies, the amount of Fc.gamma. receptor bound was divided by the amount of each antibody captured to obtain corrected values, and these values were compared. Furthermore, antibodies captured onto the chips were washed by reaction with 10 mM glycine-HCl, pH 1.5, and the chips were regenerated and used repeatedly.

[0300] Kinetic analyses for calculating the KD values of each altered antibody for Fc.gamma.R were performed according to the following method. First, antibodies of interest were captured onto the above-mentioned sensor chips, and an Fc.gamma. receptor diluted with the running buffer was allowed to interact. The Biacore Evaluation Software was used to globally fit the measured results to the obtained sensorgram using the 1:1 Langmuir binding model, and the association rate constant ka (L/mol/s) and the dissociation rate constant kd (1/s) were calculated; and from those values the dissociation constants KD (mol/L) were calculated.

[0301] When the interaction between each of the altered antibodies and Fc.gamma.R was weak, and correct analysis was determined to be impossible by the above-mentioned kinetic analysis, the KD for such interactions were calculated using the following 1:1 binding model equation described in the Biacore T100 Software Handbook BR1006-48 Edition AE.

[0302] The behavior of interacting molecules according to the 1:1 binding model on Biacore can be described by Equation 1 shown below.

R.sub.eq=CR.sub.max/(KD+C)+RI [Equation 1]

R.sub.eq: a plot of steady-state binding levels against analyte concentration C: concentration RI: bulk refractive index contribution in the sample R.sub.max: analyte binding capacity of the surface

[0303] When this equation is rearranged, KD can be expressed as Equation 2 shown below.

KD=CR.sub.max/(R.sub.eq-RI)-C [Equation 2]

[0304] KD can be calculated by substituting the values of R.sub.max, RI, and C into this equation. The values of RI and C can be determined from the sensorgram of the measurement results and measurement conditions. R.sub.max was calculated according to the following method. As a target of comparison, for antibodies that had sufficiently strong interactions as evaluated simultaneously in the same round of measurement, the R.sub.max value was obtained through global fitting using the 1:1 Langmuir binding model, and then it was divided by the amount of the comparison antibody captured onto the sensor chip, and multiplied by the captured amount of an altered antibody to be evaluated.

INDUSTRIAL APPLICABILITY

[0305] Polypeptides comprising an Fc region that have maintained or decreased binding activities towards both allotypes of Fc.gamma.RIIa, types R and H, and having enhanced Fc.gamma.RIIb-binding activity in comparison with the parent polypeptide are provided by the present invention. By using the polypeptides with enhanced binding selectivity for Fc.gamma.RIIb rather than for both allotypes of Fc.gamma.RIIa (types R and H), it is possible to transmit inhibitory signal of inflammatory immune response mediated by phosphorylation of ITIM of Fc.gamma.RIIb in patients carrying either of the allotypes, types R and H. Furthermore, by conferring an antibody Fc with the property of selective Fc.gamma.RIIb binding, anti-antibody production may be suppressed through Fc.gamma.RIIb-mediated immunosuppressive actions.
