The technology provided herein relates to antibodies, antigen binding portions, and derivatives thereof, nucleic acids encoding the antibodies, antigen binding portions, or derivatives thereof, as well as complementary nucleic acids, vectors and host cells containing the nucleic acids.
TNFα is a cytokine produced by white blood cells, including monocytes and macrophages. The cytokine stimulates and activates the immune system in response to conditions such as infection or cancer. TNFα is thought to be involved in a variety of human diseases and disorders, including sepsis, infections, autoimmune diseases, transplant rejection and graft-versus-host disease. Furthermore, over production of TNFα can lead to immunological disorders, such as rheumatoid arthritis or psoriasis.
In light of the role that TNFα plays in a human disease, antibodies that bind to TNFα have been sought for use in therapy to inhibit TNFα activity. (See, for example U.S. Pat. No. 6,090,382 to Salfeld, et al., WO2006/014477 to Crea, et al., and Rajpal, et al., PNAS 102:8466-8471). Therefore, it is important to develop human antibodies, antigen binding portions, and derivatives thereof that are capable of binding TNFα with high affinity and/or slow dissociation kinetics.
Provided herein are antibodies, antigen binding portions, or derivatives thereof that are capable of binding TNFα. In some embodiments, the antibodies or antigen binding portions thereof have improved properties such as affinity to TNFα compared to a base antibody or antigen binding portion thereof comprising the heavy and light chains of SEQ ID NOs. 1 and 2, respectively or the variable regions thereof. The heavy and light chain sequences for the antibodies and antigen binding portions and derivatives provided herein are described in terms of a base sequence having one or more alterations compared to that sequence. Alterations in the amino acid sequence are specified by providing the residue number preceded by the wild type amino acid and followed by the variant amino acid present at that position. For example, for the heavy chain having a glycine at position or residue 31 of SEQ ID NO. 1 instead of the wild type aspartate is specified as “D31G” using the one letter designation code for amino acids.
Antibodies, antigen binding portions, or derivatives thereof capable of binding TNF-α are provided.

The antibodies, antigen binding portions, or derivatives thereof can be used for preparing compositions to be administered to a patient for the treatment of diseases such as rheumatoid arthritis, inflammatory bowel disease, psoriasis, and Crohn's disease as well as other diseases connected with TNFα. The antibodies, antigen binding portions, or derivatives thereof can also be used in assays, such as diagnostic assays, to detect TNFα or measure the level of TNFα in a biological sample.
Disclosed herein are antibodies, antigen binding portions, and derivatives thereof (also referred to herein as “antibody” or “antibodies”) that are capable of binding to TNFα. The antibodies comprise one or more alterations in the amino acid sequence of the heavy and/or light chain variable regions of SEQ ID NOs. 1 and 2, respectively. It is well known to one of ordinary skill in the art that the regions of both the light chain and the heavy chain of an immunoglobulin contain antigen binding sites. The regions containing the antigen binding sites are composed of four relatively invariant “framework regions” (FRs) and three highly variant “hypervariable regions” (HVs). Because the HVs constitute the binding site for antigen(s) and determine specificity by forming a surface complementarity to the antigen, they are called the “complementarity-determining regions”, or CDRs, and are denoted CDR1, CDR2, and CDR3, and numbering begins with CDR1 at the N-terminus of the heavy or light chain, respectively.
In some embodiments, the antibodies comprise unique CDR1 regions within the variable region of the heavy chain. The antibody or antigen binding portion or derivative thereof can comprise a heavy chain variable region comprising SEQ ID NO. 1 having at least one alteration selected from the group consisting of D31 G, D31 T, D31N, D31R, Y32F, Y32Q, and A40V, and further optionally comprising a light chain variable region comprising an amino acid sequence of SEQ ID NO. 2 having at least one alteration selected from the group consisting of T129A, Q166R, and T180I. For example, the antibody or antigen binding portion or derivative thereof can comprise SEQ ID NO. 1 or residues 30-35 of SEQ ID NO. 1, wherein residue 31 is H and residue 32 is F; or wherein residue 31 is G and residue 32 is F or Q; or wherein residue 31 is N; or wherein residue 32 is S; or wherein residue 31 is T and residue 32 is F; or wherein residue 3 is G and residue 32 of SEQ ID NO. 1 is F; or wherein residue 31 of SEQ ID NO. 1 is R. In other embodiments, residue 31 is Q and further optionally comprising a light chain having SEQ ID NO. 2 wherein residue 180 of SEQ ID NO. 2 is I; or wherein residue 32 of SEQ ID NO. 1 is S or F and optionally comprising a light chain having SEQ ID NO. 2 wherein residue 166 of SEQ ID NO. 2 is R; or wherein residue 31 of SEQ ID NO. 1 is H and further optionally comprising a light chain having a sequence of SEQ ID NO. 2, wherein residue 40 of SEQ ID NO. 2 is V and residue 129 of SEQ ID NO. 2 is A.

In other embodiments, the antibodies comprise unique CDR3 region within the variable region of the heavy chain. For example, the antibody or antigen binding portion or derivative thereof can comprise SEQ ID NO. 1 or residues 99-110 of SEQ ID NO. 1, wherein residue 103 is P.
In addition, the heavy chain variable region of the antibody, antigen binding portion, or derivative thereof can further comprise at least one alteration of SEQ ID NO. 1 selected from the group consisting of D31H, D31Q, Y32S, and S100K.
In some embodiments, the antibodies comprise unique CDR1 region within the variable region of the light chain.

For example, the antibody or antigen binding portion or derivative thereof can comprise SEQ ID NO. 2 or residues 23-34 of SEQ ID NO. 2, wherein residue 24 is L and residue 25 of SEQ ID NO. 2 is S or G, and optionally wherein residue 29 of SEQ ID NO. 2 is L; or wherein residue 24 is A or T; or wherein residue 25 is S or T and optionally wherein residue 27 is M; or wherein residue 27 is Y, V, or W and optionally wherein residue 26 is T; or wherein residue 28 is S, P, R, or L and optionally wherein residue 29 is L or V.

For example, the antibody or antigen binding portion or derivative thereof can comprise SEQ ID NO. 2 or amino acids 50-56 of SEQ ID NO. 2 wherein residue 53 is W; or wherein residue 52 is W, G, or N; or wherein residue 53 is Y, F, or V and optionally wherein residue 52 is N or optionally wherein residue 57 is S; or wherein residue 53 is S and residue 214 is G and further optionally comprising a heavy chain having an amino acid sequence of SEQ ID NO. 1 wherein residue 65 is R and residue 66 is N; or wherein residue 54 of SEQ ID NO. 2 is S or T and optionally wherein residue 55 is I, K, or L; or wherein residue 56 is R.
In some embodiments, the antibodies comprise unique CDR3 region within the variable region of the light chain. The antibody or antigen binding portion or derivative thereof of can comprise a light chain variable region comprising SEQ ID NO. 2 or amino acids 89-97 of SEQ ID NO. 2 and having at least one alteration selected from the group consisting of V15M, N92I, R93Q, R93M, A94S, P95Q, P95A, P95S, P95M, P95E, and P95V.

In addition, the light chain variable region of the antibody, antigen binding portion, or derivative thereof can further comprise at least one alteration of SEQ ID NO. 2 selected from the group consisting of Q27L, Q27Y, Q27K, 129L, T53S, Q55L, N92D, R93K and A94P.
The various embodiments described herein can be complimentary and can be combined or used together in a manner understood by the skilled person in view of the teachings contained herein. Thus, the antibodies, antigen binding portions, and derivatives thereof provided herein also include combinations of the above described variations. For example, the antibody or antigen binding portion or derivative thereof can comprise SEQ ID NO. 2 having at least one alteration in the sequence selected from the group consisting of S52N, S52G, S52W, T53W, V58M, N92I, R93K, R93Q and A94P and optionally comprising a heavy chain having a sequence of SEQ ID NO. 2 and having at least one alteration selected from the group consisting of D31H, D31Q, Y32F, and Y32S.
In some embodiments, the antibodies, antigen binding portions, or derivatives thereof have improved affinity for TNFα compared to an antibody, antigen binding portion, or derivative thereof comprising the variable regions of the heavy and light chains of SEQ ID NOs. 1 and 2, respectively. Improved affinity can be a function of an improved dissociation constant KD or an improved koff rate constant. In some embodiments the improved KD dissociation constant or improved koff rate constant is at least 1.5 fold lower, or 2, 3, or 4 fold lower than that of an antibody or antigen binding fragment thereof that comprises the variable region of a heavy chain having the amino acid sequence of SEQ ID NO. 1 and the variable region of a light chain having the amino acid sequence of SEQ ID NO. 2.
In a preferred embodiment the improved KD dissociation constant or improved koff rate constant is at least 10 fold lower, or 15, 20, 30 fold lower than that of an antibody or antigen binding fragment thereof that comprises the variable region of a heavy chain having the amino acid sequence of SEQ ID NO. 1 and the variable region of a light chain having the amino acid sequence of SEQ ID NO. 2.
In some embodiments, the antibody, antigen binding portion, or derivative thereof or nucleic acid encoding same is isolated. An isolated biological component (such as a nucleic acid molecule or protein such as an antibody) is one that has been substantially separated or purified away from other biological components in the cell of the organism in which the component naturally occurs, e.g., other chromosomal and extra-chromosomal DNA and RNA, proteins and organelles. Nucleic acids and proteins that have been “isolated” include nucleic acids and proteins purified by standard purification methods. The term also embraces nucleic acids and proteins prepared by recombinant expression in a host cell as well as chemically synthesized nucleic acids.
Amino acids are referred to herein using the name of the amino acid, the three letter abbreviation or the single letter abbreviation. The table below provides a list of the standard amino acids together with their abbreviations.
In addition to the specific amino acid variations and nucleic acids encoding the variations, conservative amino acid substitutions of the variations are provided herein. Such substitutions are those which are conservative, for example, wherein the variant amino acid is replaced by another amino acid of the same general type. Amino acids can be classified as acidic, basic, neutral and polar, or neutral and nonpolar and/or aromatic, depending on their side chain. Preferred substitutions of a variant amino acid position include those that have one or more classifications that are the same as the variant amino acid at that position. Thus, in general, amino acids Lys, Arg, and H is are basic; amino acids aspartic and glutamic are acidic; amino acids Ser, Thr, Cys, Gln, and Asn are neutral polar; amino acids Gly, Ala, Val, Ile, and Leu are nonpolar aliphatic, and amino acids Phe, Trp, and Tyr are aromatic. Gly and Ala are small amino acids and Val, Ile and Leu are alipathic amino acids.
As described herein, antigen binding fragments and derivatives thereof of an antibody includes any portion of an antibody that specifically binds to the antigen. For example, an antigen-binding fragment of an antibody includes molecules in which one or more immunoglobulin chain is not full length but which is capable of specifically binding to the antigen. Examples of binding fragments encompassed within the term “antigen binding fragment thereof” include, for example, (i) a Fab fragment, e.g., a monovalent fragment consisting of the VL, VH, CL and CH1 domains; (ii) a F(ab′)2 fragment, a bivalent fragment comprising two Fab fragments linked by a disulfide bridge at the hinge region; (iii) a Fd fragment consisting of the VH and CH1 domains; (iv) a Fv fragment consisting of the VL and VH domains of a single arm of an antibody, (v) a dAb fragment (Ward et al., (1989) Nature 341:544-546), which consists of a VH domain; and (vi) an isolated complementarity determining region (CDR) having sufficient framework capable of specifically binding to the antigen, e.g., an antigen binding portion of a variable region. An antigen binding portion of a light chain variable region and an antigen binding portion of a heavy chain variable region, e.g., the two domains of the Fv fragment, VL and VH, can be joined, using recombinant methods, by a synthetic linker that enables them to be made as a single protein chain in which the VL and VH regions pair to form monovalent molecules (known as single chain Fv (scFv); see e.g., Bird et al. (1988) Science 242:423-426; and Huston et al. (1988) Proc. Natl. Acad. Sci. USA 85:5879-5883). Such single chain antibodies are also intended to be encompassed within the term “antigen-binding fragment thereof”. These antibody fragments are generated using conventional techniques known to those of ordinary skill in the art, and the fragments are screened for binding ability in the same manner as are intact antibodies. The aforementioned antibody, antigen binding portion, or derivative thereof also encompass recombinant binding proteins which comprise in addition to the aforementioned TNF-alpha binding domain one or more additional domains with binding affinities to other proteins and/or epitops, such as Diabodies, Bis-scFvs, bispecific Fab2 or trispecific Fab3 (see, P. Holliger and P. J. Hudson, Nature Biotechnology, 2005, Vol. 23, Number 9, page 1126-1136). These binding proteins are generated using conventional techniques known to those of ordinary skill in the art, and the fragments are screened for binding ability in the same manner as are intact antibodies. In addition, the antibody, antigen binding portion, or derivative thereof is a human antibody e.g. can be of human origin or being humanized. While human antibodies or fragments or derivatives thereof are preferred, other antibodies which can be employed in the molecules of the invention are murine, chimeric and humanized antibodies. These chimeric or humanized antibodies and antibody fragments are generated using conventional techniques known to those of ordinary skill in the art. Human monoclonal antibodies or fragments and derivatives thereof are preferred.
In addition, the antibody, antigen binding portion, or derivative thereof can be derivatized, for example to improve its biochemical stability or to conjugate it to a detectable label or therapeutic agent. For example, the antibody, antigen binding portion, or derivative thereof can be conjugated to a polymeric backbone, such as polyethylene glycol (“PEG”), cellulose, dextran, agarose, or an amino acid copolymer. Other examples of derivatization include labeling with radioactive isotopes, fluorophores, chemiluminescent agents, cell toxic agents and enzymes. These modifications can readily be made by one of ordinary skill in the art such that the ability of the antibodies or antigen binding portions or derivatives thereof to bind TNFα remains intact.
It is well known to one of ordinary skill in the art that the genetic code is degenerate, that is more than one codon triplet can code for the same amino acid. Therefore, the nucleic acids provided herein also include alternate sequence that use different codons to encode the same amino acid sequence. Furthermore, the nucleic acids provided herein also include both the coding sequence and the complementary sequence of nucleic acids encoding the antibodies, antigen binding fragments thereof and derivatives thereof provided herein.
The altered heavy and light chains or variable regions thereof provided herein can be generated by standard methods in the art. For example, to generate the altered heavy chain, one of ordinary skill in the art can mutagenize the base nucleic acid sequence such that the resulting mutagenized sequence encodes the altered heavy chain. In one embodiment, the base sequence for the heavy chain is provided in SEQ ID NO. 3. Similarly, to generate the altered light chain, one or ordinary skill in the art can mutagenize SEQ ID NO. 4 such that the resulting mutagenized sequence encodes the altered light chain. As described herein, it is understood that because of the degeneracy of the genetic code, the base nucleic sequence can be different from that shown in SEQ ID NO. 3 or 4 and still encode the amino acid sequences of SEQ ID NO. 1 or 2, respectively.
One of ordinary skill in the art can readily mutagenize a sequence that encodes the desired heavy or light chain even where the nucleic acid sequence uses different codons to encode the amino acid sequence. The nucleic acid to be used in the mutagenesis can be made, for example, using chemical synthesis methods that are known in the art, or for example by PCR assembly of oligonucleotides or ligation of oligonucleotides to generate the base sequence. The alterations in the nucleic acid sequence can be made using oligonucleotides designed to incorporate specific changes at predetermined positions within the encoding nucleic acids (e.g., by oligonucleotide mutagenesis). Mutagenesis methods as described by Kunkle et al., Proc. Natl. Acad. Sci. U.S.A., 82:488-492 (1985) are suitable methods. Other suitable methods known in the art such include PCR mutagenesis. Site-directed mutagenesis (Carter et al., Nucl. Acids Res., 13:4331 (1986); Zoller et al., Nucl. Acids Res., 10:6487 (1987)), cassette mutagenesis Wells et al., Gene, 34:315 (1985), restriction selection mutagenesis (Wells et al., Philos. Trans. R. Soc. London SerA, 317:415 (1986)). Polynucleotides encoding the altered heavy or light chains can also be made, for example, by direct synthesis of the nucleic acid sequence encoding the altered amino acid sequence.
An antibody, antigen binding portion, or derivative thereof provided herein can be prepared by recombinant expression of nucleic acid sequences encoding light and heavy chains or portions thereof in a host cell. To express an antibody, antigen binding portion, or derivative thereof recombinantly, a host cell can be transfected with one or more recombinant expression vectors carrying DNA fragments encoding the light and/or heavy chains or portions thereof such that the light and heavy chains are expressed in the host cell. Standard recombinant DNA methodologies are used prepare and/or obtain nucleic acids encoding the heavy and light chains, incorporate these nucleic acids into recombinant expression vectors and introduce the vectors into host cells, such as those described in Sambrook, Fritsch and Maniatis (eds), Molecular Cloning; A Laboratory Manual, Second Edition, Cold Spring Harbor, N.Y., (1989), Ausubel, F. M. et al. (eds.) Current Protocols in Molecular Biology, Greene Publishing Associates, (1989) and in U.S. Pat. No. 4,816,397 by Boss et al.
In addition, the nucleic acid sequences encoding variable regions of the heavy and/or light chains can be converted, for example, to nucleic acid sequences encoding full-length antibody chains, Fab fragments, or to scFv. The VL- or VH-encoding DNA fragment can be operatively linked, (such that the amino acid sequences encoded by the two DNA fragments are in-frame) to another DNA fragment encoding, for example, an antibody constant region or a flexible linker. The sequences of human heavy chain and light chain constant regions are known in the art (see e.g., Kabat, E. A., et al. (1991) Sequences of Proteins of Immunological Interest, Fifth Edition, U.S. Department of Health and Human Services, NIH Publication No. 91-3242) and DNA fragments encompassing these regions can be obtained by standard PCR amplification.
To create a polynucleotide sequence that encodes a scFv, the VH- and VL-encoding nucleic acids can be operatively linked to another fragment encoding a flexible linker such that the VH and VL sequences can be expressed as a contiguous single-chain protein, with the VL and VH regions joined by the flexible linker (see e.g., Bird et al. (1988) Science 242:423-426; Huston et al. (1988) Proc. Natl. Acad. Sci. USA 85:5879-5883; McCafferty et al., Nature (1990) 348:552-554).
To express the antibodies, antigen binding portions or derivatives thereof standard recombinant DNA expression methods can be used (see, for example, Goeddel; Gene Expression Technology. Methods in Enzymology 185, Academic Press, San Diego, Calif. (1990)). For example, DNA encoding the desired polypeptide can be inserted into an expression vector which is then transfected into a suitable host cell. In some embodiments, the DNAs encoding the heavy and light chains are inserted into separate vectors. In other embodiments, the DNA encoding the heavy and light chains are inserted into the same vector. It is understood that the design of the expression vector, including the selection of regulatory sequences is affected by factors such as the choice of the host cell, the level of expression of protein desired and whether expression is constitutive or inducible.
Preferred regulatory sequences for mammalian host cell expression include viral elements that direct high levels of protein expression in mammalian cells, such as promoters and/or enhancers derived from cytomegalovirus (CMV) (such as the CMV promoter/enhancer), Simian Virus 40 (SV40) (such as the SV40 promoter/enhancer), adenovirus, (e.g., the adenovirus major late promoter (AdMLP)) and polyoma. For further description of viral regulatory elements, and sequences thereof, see e.g., U.S. Pat. No. 5,168,062 by Stinski, U.S. Pat. No. 4,510,245 by Bell et al. and U.S. Pat. No. 4,968,615 by Schaffner et al. The recombinant expression vectors can also include origins of replication and selectable markers (see e.g., U.S. Pat. Nos. 4,399,216, 4,634,665 and U.S. Pat. No. 5,179,017, by Axel et al.). Suitable selectable markers include genes that confer resistance to drugs such as G418, hygromycin or methotrexate, on a host cell into which the vector has been introduced. For example, the dihydrofolate reductase (DHFR) gene confers resistance to methotrexate and the neo gene confers resistance to G418.
Transfection of the expression vector into a host cell can be carried out using standard techniques such as electroporation, calcium-phosphate precipitation, and DEAE-dextran transfection.
Suitable mammalian host cells for expressing the antibodies, antigen binding portions, or derivatives thereof provided herein include Chinese Hamster Ovary (CHO cells) (including dhfr-CHO cells, described in Urlaub and Chasin, (1980) Proc. Natl. Acad. Sci. USA 77:4216-4220, used with a DHFR selectable marker, e.g., as described in R. J. Kaufman and P. A. Sharp (1982) Mol. Biol. 159:601-621), NSO myeloma cells, COS cells and SP2 cells. In some embodiments, the expression vector is designed such that the expressed protein is secreted into the culture medium in which the host cells are grown. The antibodies, antigen binding portions, or derivatives thereof can be recovered from the culture medium using standard protein purification methods.
The antibodies, antigen binding portions, or derivatives thereof can also be produced in prokaryotic cells using suitable vectors as described, for example, in U.S. Pat. No. 6,204,023 to Robinson, et al and in (Carter et al., Bio/Technology 10:163-167 (1992). The expression vector can be designed to allow the expressed polypeptide to be secreted into the periplasmic space of gram-negative bacteria, or the extracellular space of gram-positive bacteria or yeasts, or the polypeptide can be retained within the cell, for example, in inclusion bodies. It is well-known to anyone skilled in the are that the sequences provided herein for heavy and light chain antibodies and fragments thereof can be operatively linked to functional elements that direct the expression to the respective spaces, such functional elements comprising for example leader sequences. The expressed polypeptide can be isolated from the periplasmic space or the inclusion bodies can be isolated from the host cell, respectively. For example, Fab′-SH fragments can be directly recovered from E. coli and chemically coupled to form F(ab′)2 fragments (Carter et al., (1992)). In another embodiment, the antibodies, antigen binding portions, or derivatives thereof may be produced by homologous recombination, e.g. as described in U.S. Pat. No. 5,204,244.
Suitable host cells for cloning or expressing the DNA in the vectors herein are the prokaryote, yeast, or higher eukaryote cells described above. In addition to prokaryotes, eukaryotic microbes such as filamentous fungi or yeast are suitable cloning or expression hosts for the antibodies, antigen binding portions, or derivatives thereof provided herein. Saccharomyces cerevisiae, is a suitable eukaryotic host microorganism. Another suitable yeast host is Schizosaccharomyces pombe. Suitable host cells for the expression of glycosylated antibodies, antigen binding portions, or derivatives thereof provided herein include mammalian, plant, and insect cells. The antibodies, antigen binding portions, or derivatives thereof can be recovered from the culture medium using standard protein purification methods, including but not limiting to hydroxylapatite chromatography, gel electrophoresis, dialysis, recombinant tag purification (such as HA-tag, Myc-tag, His-tag) and affinity chromatography.
Host cells are transformed with the above-described expression or cloning vectors for antibodies, antigen binding portions, or derivatives thereof production and cultured in conventional nutrient media modified as appropriate for inducing promoters, selecting transformants, or amplifying the genes encoding the desired sequences. Commercially available media such as Ham's F10, Minimal Essential Medium (MEM), RPMI-1640, and Dulbecco's Modified Eagle's Medium (DMEM), are suitable for culturing the host cells. The culture conditions, such as temperature, pH, and the like, are those previously used with the host cell selected for expression, and will be apparent to the ordinarily skilled artisan.
When using recombinant techniques, the antibody can be produced intracellularly, in the periplasmic space, or directly secreted into the medium. If the antibody is produced intracellularly, as a first step, the particulate debris, either host cells or lysed fragments, is removed, for example, by centrifugation or ultrafiltration. Carter et al., Bio/Technology 10:163-167 (1992) describe a procedure for isolating antibodies which are secreted to the periplasmic space of E. coli. Briefly, cell paste is thawed in the presence of sodium acetate (pH 3.5), EDTA, and phenylmethylsulfonylfluoride (PMSF) over about 30 min. Cell debris can be removed by centrifugation. Where the antibody is secreted into the medium, supernatants from such expression systems are generally first concentrated using a commercially available protein concentration filter, for example, an Amicon or Millipore Pellicon ultrafiltration unit. A protease inhibitor such as PMSF may be included in any of the foregoing steps to inhibit proteolysis and antibiotics may be included to prevent the growth of adventitious contaminants.
The antibody composition prepared from the cells can be purified using, for example, ion exchange chromatography, hydrophobic interaction chromatography, size exclusion chromatography, hydroxylapatite chromatography, gel electrophoresis, dialysis, and affinity chromatography.
The antibodies, antigen binding fragments thereof and derivatives thereof are shown to bind TNF-α by ELISA assay and/or HTRF assay, other assay formats known to anyone skilled in the art can be applied as well. Many of the antibodies, antigen binding fragments thereof and derivatives thereof provided herein bind to TNF-α at least as well as a Fab fragment of the anti-TNFα monoclonal antibody D2E7 (comprising SEQ ID NO. 1 and SEQ ID NO. 2). The assays demonstrate that many of the variants have a reduced off-rate compared to the antigen binding fragment of D2E7.
The antibodies, antigen binding portions, or derivatives thereof provided herein can be administered to a patient in need thereof. A variety of routes can be used to administer the antibody, antigen binding portion or derivative thereof. Any mode of administration that is medically acceptable, meaning any mode that produces effective levels of the active compounds without causing clinically unacceptable adverse effects can be used to administer the antibody, antigen binding portion or derivative thereof. Such modes of administration include oral, sublingual, topical, nasal, transdermal or parenteral routes. The term “parenteral” includes subcutaneous, intravenous, intramuscular, or infusion.
The antibody, antigen binding portion or derivative thereof can be administered once, continuously, such as by continuous pump, or at periodic intervals. The periodic interval may be weekly, bi-weekly, or monthly. The dosing can occur over the period of one month, two months, three months or more to elicit an appropriate humoral, cellular immune and/or clinical response. Desired time intervals of multiple doses of a particular composition can be determined without undue experimentation by one skilled in the art. Other protocols for the administration of an antibody or antigen binding fragment thereof will be known to one of ordinary skill in the art, in which the dose amount, schedule of administration, sites of administration, mode of administration and the like vary from the foregoing.
In yet another embodiment, the antibodies, antigen binding portions, or derivatives thereof provided herein can be used to detect TNFα in a biological sample, in vivo, ex vivo or in vitro. Suitable biological samples include, e.g., a tissue sample, a body fluid sample or a cell sample that is expected to contain TNFα. This can be achieved, for example, by contacting a sample to be tested, optionally along with a control sample, with the antibody, antigen binding portion, or derivative thereof under conditions that allow for formation of a complex between the antibody and TNFα, if present in the sample. Complex formation can then be detected, for example using enzyme linked immunosorbant assay (ELISA).

SPR-Analysis:
Surface plasmon resonance analysis: TNFα preparations were immobilized onto a GLC sensor chip within a ProteOn XPR biosensor (BioRad Laboritories) using standard amine coupling. The surfaces were activated for 5 minutes with sulf-NHS/EDC (0.01M/0.04 M), then the TNFα was injected at 1 ug/ml in 10 mM NaAcetate, pH 4.5 for 5 minutes and finally the surfaces were blocked with a 5 minute injection of 1 M ethanolamine pH 8.1. TNFa immobilization levels were between 400 and 500 RU. Fabs were tested at 10 nM as the highest concentration in a 3-fold dilution series. The running buffer contained 10 mM HEPES, 150 mM NaCl, pH 7.4, with 0.005% tween-20 and 0.1 mg/mL BSA. Binding data were collected at 25 degrees C. The binding kinetics were determined by globally fitting the response data to a simple 1:1 interaction model using Scrubber (Biologic Software Pty Ltd, Australia).
Table 1 is showing the variants of the invention and the corresponding SEQ ID NO. For example the sequence of the heavy chain of URS—1i!L—1.12A—20.1—2 has SEQ ID NO: 63 and the sequence of the light chain of URS—1i!L—1.12A—20.1—2 has SEQ ID NO: 64. When no corresponding heavy or light chain is indicated the D2E7 heavy or light chain is used.
The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The foregoing embodiments are therefore to be considered in all respects illustrative rather than limiting on the invention described herein. Scope of the invention is thus indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
This application is a national phase of PCT/EP2008/011120 filed on Dec. 24, 2008, which claims the benefit of Ser. No. 61/018,436 filed on Dec. 31, 2007.
