Determine the number of matched positions to get the number of matched positions in the comparison window. Divide by the total number of positions in the sequence and multiply the result by 100 to get the percentage of sequence identity. The result is the percent identity of the subject sequence to the query sequence. The percent identity between two sequences is the result of optimal alignment of the two sequences. These arrangements take into account the number of gaps that need to be introduced and the length of each gap. It is a function of the number of identical positions shared by the columns.

[0346] 2. Further Modifications of the Framework or Fc Region The immunoconjugates of the invention may, for example, be modified in VH and / or VH sequences to improve antibody properties. The modified antibody or its antigen-binding domain further comprises modifications to framework residues within the VL. In some embodiments, framework modifications may be made to enhance the immunogenicity of the antibody. For example, one approach is to replace one or more framework residues with the corresponding germline residues. More specifically, antibodies that have undergone somatic mutation are It may contain framework residues that differ from the germline sequence from which the antibody is derived. The basis for this is to compare the antibody framework sequences to the germline sequences from which the antibody is derived. Somatic mutations can be performed to restore the framework region sequences to their germline configuration. can be "backmutated" to the germline sequence by, for example, site-directed mutagenesis. Such "backmutated" antibodies are also intended to be encompassed by the present invention.

[0347] Another mode of framework modification is to modify the amino acid sequence within the framework region or additionally within one or more CDR regions. Mutating one or more residues within the region to remove T cell epitopes, thereby reducing antibody latency This approach involves reducing the specific immunogenicity of a given antigen. This approach is also called "deimmunization" and is This is further described in U.S. Patent Application Publication No. 20030153043 by S. et al.

[0348] In addition to or instead of modifications made within the framework or CDR regions, Within the Fc region, antibodies typically contain one or more functional properties of the antibody, such as serum half-life, complementation, etc. The antibodies may be engineered to include modifications that alter antibody binding, Fc receptor binding, and / or antigen-dependent cytotoxicity. Additionally, the antibodies of the present invention may be chemically modified (e.g., by one or more chemical the glycosylation of the antibody, and further modify one or more of the antibody's Each of these embodiments is described in more detail below. It is stated.

[0349] In one embodiment, the hinge region of CH1 is modified by altering the number of cysteine ​​residues in the hinge region. This technique is based on the US method by Bodmer et al. The hinge region of CH1 is further described in US Pat. No. 5,677,425. The number of cysteine ​​residues in the ribonucleotides may be altered to, for example, facilitate assembly of the light and heavy chains. Or the stability of the antibody is increased or decreased.

[0350] In another embodiment, the mutation in the Fc hinge region of the antibody reduces the biological half-life of the antibody. More specifically, the antibody Staphylococcus aureus protein A ( SpA) is reduced compared to the SpA binding of the native Fc hinge domain. One or more amino acid mutations are introduced into the CH2-CH3 domain interface region of the Fc hinge fragment. This technique is further described in U.S. Pat. No. 6,165,745 to Ward et al. It is being done.

[0351] In yet another embodiment, the Fc region is modified with at least one amino acid residue replaced by a different amino acid. The antibody effector functions are modified by replacing the amino acid residues with amino acid residues. The antibody has an altered affinity for the effector ligand but retains the antigen-binding ability of the parent antibody. One or more amino acids can be replaced with different amino acid residues, such as The effector ligand with altered properties is, for example, an Fc receptor or the C1 component of complement. This technique is described, for example, in U.S. Pat. No. 5,624,822, both to Winter et al. No. 1 and No. 5,648,260.

[0352] In another embodiment, the antibody has modified C1q binding and / or reduced or eliminated C1q binding. One or more amino acid residues selected from the group consisting of α- and β-glucan-1, ... The amino acids in the nucleotide sequence can be replaced with different amino acid residues. No. 6,194,551 to Ogie et al.

[0353] In another embodiment, one or more amino acid residues are modified to enhance the ability of the antibody to fix complement. This technique is described, for example, in WO 94 / 2935 by Bodmer et al. In certain embodiments, the antibodies or antigen-binding fragments thereof of the present invention are described in pamphlet No. 1. One or more amino acids of the fragment are replaced by one or more allotypic amino acid residues. The amino acid residues of the allotypes are as follows: Jefferis et al., MAbs.1: IgG1, IgG2 and IgG3 subclasses, as described in J. Immunol. 1999, 332-338 (2009) The constant region of the heavy chain of the kappa isotype and the constant region of the light chain of the kappa isotype are also included. Not limited.

[0354] In yet another embodiment, the Fc region is modified by one or more amino acids to provide a Increase the ability of the antibody to mediate ADCC and / or Fcγ receptors The antibody is modified to increase its affinity for the antibody. This technique is described, for example, in Pres. Furthermore, human IgG 1, which matches the binding sites for FcγRI, FcγRII, FcγRIII, and FcRn. Shield has been tested and mutants with improved binding have been described (Shield s et al., J. Biol. Chem. 276:6591-6604, 2001. See the reference.

[0355] In yet another embodiment, the glycosylation of the antibody is modified. For example, an aglycosylated antibody Glycosylation can be altered to produce antibodies that lack glycosylation, e.g. For example, carbohydrate modifications can increase the affinity of an antibody for an "antigen." This can be achieved, for example, by modifying one or more glycosylation sites within the antibody sequence. For example, one or more amino acid substitutions may be made to modify one or more variable region framework sequences. The glycosylation site of the target protein may be abolished, thereby abolishing glycosylation at that site. Such aglycosylation may increase the affinity of the antibody for the antigen. Techniques are described, for example, in U.S. Pat. Nos. 5,714,350 and 6,355,235 by Co et al. This is described in specification 0,861.

[0356] Additionally or alternatively, antibodies with altered glycosylation patterns, e.g., the amount of fucosyl residues Hypofucosylated antibodies with reduced or increased bisecting GlcNac structures Such alterations in glycosylation patterns can improve the ADCC ability of antibodies. These carbohydrate modifications have been demonstrated to increase the glycosylation machinery, for example. This can be achieved by expressing the antibody in a host cell where the glycosylation machinery has been modified. The modified cells have been described in the art and are capable of expressing and carrying out the recombinant antibodies of the invention. The host cells can be used to produce antibodies with modified glycosylation. Ang et al., European Patent No. 1,176,195, discloses a method for producing fucosyltransferases. described a cell line with a functionally disrupted FUT8 gene that encodes Antibodies expressed in the cell lines shown in this publication exhibit low fucosylation. No. 03 / 035835 pamphlet describes a carbohydrate derivative with fucose linked to Asn(297). They described a mutant CHO cell line, Lecl3, that has a reduced ability to bind to ATP. , they also result in hypofucosylation of antibodies expressed in their host cells (Shie lds.et al.,(2002)J.Biol.Chem.277:26733-2 (See also WO 99 / 54342 by Umana et al.) The results show that antibodies expressed in engineered cell lines result in increased ADCC activity of the antibody. Glycoproteins were modified with glycosyltransferases, showing an increase in bisecting GlcNac structures. transferases (e.g., β(1,4)-N-acetylglucosaminyltransferases) describes a cell line engineered to express globin-transferase III (GnTIII). (Umana et al., Nat.Biotech.17:176-180,199 See also 9).

[0359] The present invention also provides polynucleotides encoding the antibodies described herein, such as those described herein. A fragment encoding a heavy or light chain variable region or segment containing a complementarity determining region as set forth in In some embodiments, a polynucleotide encoding a heavy chain variable region is further provided. The oligonucleotide is selected from the group consisting of SEQ ID NOs: 8, 28, 48, 68, 88, 108 and 151. and at least 85%, 89%, 90%, 91%, 92% , 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% nucleic acid sequence identity In some embodiments, the polynucleotide encoding the light chain variable region has , SEQ ID NOs: 18, 38, 58, 78, 98, 118 and 153 Polynucleotides and at least 85%, 89%, 90%, 91%, 92%, 93%, 94 %, 95%, 96%, 97%, 98%, 99% or 100% nucleic acid sequence identity.

[0360] In some embodiments, the polynucleotide encoding the heavy chain is SEQ ID NO: 10, 30 , 50, 70, 90, 110 or 152 polynucleotides and at least 85%, 89% , 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% nucleic acid sequence identity.

Nucleotides and at least 85%, 89%, 90%, 91%, 92%, 93%, 94%, having 95%, 96%, 97%, 98%, 99% or 100% nucleic acid sequence identity.

[0361] The polynucleotides of the present invention may encode only the variable region sequences of the antibodies. The polynucleotide sequence may encode both the variable and constant regions of the polypeptide. Some contain both the heavy and light chain variable regions of one of the exemplified anti-P-cadherin antibodies. Several other polynucleotides encode polypeptides containing the heavy chains of antibodies. and two polypeptide segments that are substantially identical to the variable region of the light chain.

[0362] The polynucleotide sequences may be prepared by de novo solid-phase DNA synthesis or by the synthesis of antibodies or their binding fragments. PCR mutagenesis of existing sequences encoding fragments (e.g., sequences described in the Examples below) Direct chemical synthesis of nucleic acids can be performed by the method of Narang et al., Me phosphotriester method of Enzymol. 68:90, 1979; Brown et al. phosphodiester method of T. et al., Meth. Enzymol. 68:109, 1979 ;Beaucage et al.,Tetra.Lett.,22:1859,198 1 diethyl phosphoramidite method; and the solid-state method of U.S. Pat. No. 4,458,066. This can be achieved by methods known in the art, such as support methods. Mutations can be introduced into the nucleotide sequence using, for example, PCR Technology: ciples and Applications for DNA Amplific ation, H.A. Erlich (Ed.), Freeman Press, NY, N. Y,1992;PCR Protocols: A Guide to Methods and Applications, Innis et al. (Ed.), Acade mic Press, San Diego, CA, 1990;Mattila et a I., Nucleic Acids Res. 19:967, 1991; and Ecker t et al., PCR Methods and Applications 1: 17, 1991.

[0363] Expression vectors and host cells for producing the antibodies described herein are also provided herein. A variety of expression vectors can be used to express polynucleotides encoding antibody chains or binding fragments. Viral-based and non-viral expression vectors can be used to express the peptide. Any of the non-viral vectors can be used to produce antibodies in mammalian host cells. Viral vectors and non-viral systems use plasmids, typically expressing proteins or RNA. These include episomal vectors and human artificial chromosomes with expression cassettes for , Harrington et al., Nat Genet 15:345,1997 For example, anti-P-cadherin antibodies in mammalian (e.g., human) cells Non-viral vectors useful for expressing oligonucleotides and polypeptides include pTh ioHis A, B and C, pcDNA™3.1 / His, pEBVHis A, B and C (Invitrogen, San Diego, CA), MPSV vectors and Many other vectors known in the art are available for expressing other proteins. Useful viral vectors include retroviruses, adenoviruses, and adeno-associated viruses. virus, herpesvirus-based vectors, SV40, papillomavirus, HBP Stein-Barr virus, vaccinia virus vectors and Semliki Forest virus (S Examples of vectors based on FV include Brent et al. (supra); Smith , Annu. Rev. Microbiol. 49:807, 1995; and Rosenf See Eld et al., Cell 68:143, 1992.

[0364] The choice of expression vector will depend on the intended host cell in which the vector will be expressed. Typically, the expression vector contains a polynucleotide encoding an anti-P-cadherin antibody chain or fragment. A promoter and other control sequences (e.g., enhancers) operably linked to the In some embodiments, the expression of the inserted sequence is prevented except under inducing conditions. An inducible promoter is used to induce the expression of the α-amyloid β-glucan. promoters such as lacZ, metallothionein promoter, or heat shock promoters. Cultures of transformed organisms are grown to ensure that their expression products are well tolerated by the host cells. It can be grown under non-inducing conditions without biasing the population of coding sequences. In addition to the promoter, other regulatory elements are required for efficient expression of the antibody chain or fragment. These elements may be present or required. Typically, the expression efficiency depends on the cell type used. It can also be enhanced by incorporating enhancers suitable for the cell system (e.g., Sc harf et al.,Results Probl.Cell Differ.20 :125, 1994; and Bittner et al., Meth. Enzymol. , 153:516, 1987). For example, the SV40 enhancer or CM The V enhancer can be used to increase expression in mammalian host cells.

[0365] The expression vector contains a fusion protein with the polypeptide encoded by the inserted antibody sequence. It may also provide a secretory signal sequence for forming a protein. The antibody sequence is linked to a signal sequence before inclusion in the vector. The vectors used to receive the sequences encoding the heavy and low chain variable domains are stationary. Such vectors may encode a fusion protein with a constant region or a portion thereof. This allows for the expression of variable regions as proteins, thereby producing intact antibodies or fragments thereof. Typically, such constant regions are human constant regions.

[0366] Host cells for harboring and expressing antibody chains can be either prokaryotic or eukaryotic. E. coli has been used to clone and express the polynucleotides of the present invention. Other microbial hosts suitable for use include Bacillus subtilis. Bacillus such as Bacillus subtilis and Salmonella monella species, Serratia species and various Pseudomonas ( These prokaryotic hosts include other Enterobacteriaceae, such as Pseudomonas species. The host cell typically contains expression control sequences compatible with the host cell (e.g., an origin of replication). In addition, expression vectors using the lactose promoter system, tryptophan, Fan (trp) promoter system, beta-lactamase promoter system or Phagilla There are also any number of different known promoters, such as promoter systems derived from Muda. The promoter typically controls expression, optionally with an operator sequence, and initiates transcription. and a ribosome binding site sequence for initiating and terminating translation. Other microbes, such as yeast, may also be used to express antibody polypeptides. Insect cells in combination with vectors can also be used.

[0367] In some preferred embodiments, mammalian host cells are used to produce antibody polypeptides of the invention. For example, they are produced by expressing peptides that express endogenous immunoglobulin genes. hybridoma cell lines (e.g., myeloma hybridoma clones described in the Examples) or mammalian cell lines carrying exogenous expression vectors (e.g., SP2 / These can be any normal non-immortal or normal young myeloma cells. or abnormal immortal animal or human cells. For example, CHO cell lines, various Co including s cell lines, HeLa cells, myeloma cell lines, transformed B cells and hybridomas. Several suitable host cell lines capable of secreting intact immunoglobulins have been developed. The use of mammalian tissue cell cultures to express polypeptides is described, e.g. For example, Winnacker, From Genes to Clones, VCH Pu Blishers, NY, NY, 1987. Mammalian host cells The expression vector for the present invention contains expression control sequences such as an origin of replication, a promoter, and an enhancer. (See, e.g., Queen, et al., Immunol. Rev. 89:49-68, 1 986) as well as ribosome binding sites, RNA splice sites, polyadenylation sites, It may contain necessary processing information sites, such as nucleotide sequences and transcription terminator sequences. These expression vectors usually contain promoters derived from mammalian genes or mammalian Suitable promoters include constitutive promoters. , cell type-specific promoters, developmental stage-specific promoters and / or modulatable promoters Useful promoters include promoters such as Tarothionein promoter, constitutive adenovirus major late promoter, dexamethasone Zone-inducible MMTV promoter, SV40 promoter, MRP pol III promoter promoter, constitutive MPSV promoter, tetracycline-inducible CMV promoter (human constitutive CMV promoters and those known in the art, such as the immediate early CMV promoter Examples include, but are not limited to, promoter-enhancer combinations.

[0368] Methods for introducing expression vectors containing polynucleotide sequences of interest include the introduction of vectors into cell host species. For example, calcium chloride transfection is used in prokaryotic cells. While commonly used for erythropoietin, calcium phosphate treatment or elec- trolysis is used for other cellular hosts. Microporation can be used (see generally Sambrook et al., 2012 ,MOLECULAR CLONING:A LABORATORY MANUAL,v See volumes 1-4, Cold Spring Harbor Press, NY. Other methods include electroporation, calcium phosphate Processing, liposome-mediated transformation, injection and microinjection, ballistics method, virosomes, immunoliposomes, polycation:nucleic acid conjugates, naked DNA, human virions, fusion with the herpesvirus structural protein VP22 (Elliot and O'Hare, Cell 88:223, 1997), drug-enhanced uptake of DNA These include ex vivo transduction and ex vivo transduction. For example, stable expression of antibody chains or binding fragments is often desirable. The cell line contains a viral origin of replication or endogenous expression elements and a selectable marker gene. After the vector is introduced, the cells are cultured in a rich medium. After 1-2 days of growth in the medium, they can be switched to selective media. The purpose of the present invention is to confer resistance to selection for the introduced sequence in selective media. Allows for the growth of cells that express the gene without problems. Resistant and stably transfected cells can be grown using tissue culture methods appropriate to the cell type.
