Definitions
- the present invention relates to a method for engineering and manufacturing of a modified immunoglobulin .
- the general field is the engineering of proteins with the aim to impart them with specific binding properties . More specifically, the engineered proteins of relevance here are immunoglobulins (antibodies ) , and even more specifically, single domains or pairs or combinations of single domains of immunoglobulins .
- immunoglobulins antibodies
- the specific binding properties of immunoglobulins are important features since they control the interaction with other molecules such as antigens , and render immunoglobulins useful for diagnostic and therapeutic applications .
- the basic antibody structure will be explained here using as example an intact IgGl immunoglobulin .
- the heavy chains each have four domains .
- the amino terminal variable domains (VH) are at the tips of the Y . These are followed by three constant domains : CHl , CH2 , and the carboxy terminal CH3, at the base of the Y ' s stem.
- a short stretch, the switch connects the heavy- chain variable and constant regions .
- the hinge connects CH2 and CH3 (the Fc fragment) to the remainder of the antibody (the Fab fragments ) .
- One Fc and two identical Fab fragments can be produced by proteolytic cleavage of the hinge in an intact antibody molecule .
- the light chains are constructed of two domains , variable (VL) and constant (CL) , separated by a switch .
- Disulfide bonds in the hinge region connect the two heavy chains .
- the light chains are coupled to the heavy chains by additional disulfide bonds .
- Asn-linked carbohydrate moieties are attached at different positions in constant domains depending on the class of immunoglobulin .
- For IgGl two disulfide bonds in the hinge region, between Cys235 and Cys238 pairs , unite the two heavy chains .
- the light chains are coupled to the heavy chains by two additional disulfide bonds , between Cys229s in the CHl domains and Cys214s in the CL domains .
- Carbohydrate moieties are attached to Asn306 of each CH2 , generating a pronounced bulge in the stem of the Y .
- variable regions of both the heavy and light chains (VH) and (VL) lie at the "tips" of the Y, where they are positioned to react with antigen .
- This tip of the molecule is the side on which the N-terminus of the amino acid sequence is located.
- the stem of the Y proj ects in a way to efficiently mediate effector functions such as the activation of complement and interaction with Fc receptors , or ADCC and ADCP . Its CH2 and CH3 domains bulge to facilitate interaction with effector proteins .
- the C- terminus of the amino acid sequence is located on the opposite side of the tip, which can be termed "bottom" of the Y .
- the structure of an intact IgGl is illustrated in Figure Ia .
- lambda ( ⁇ ) and kappa (K) Two types of light chain, termed lambda ( ⁇ ) and kappa (K) , are found in antibodies .
- a given immunoglobulin either has K chains or ⁇ chains , never one of each . No functional difference has been found between antibodies having ⁇ or K light chains .
- FIG. Ib The structural organization of the main human immunoglobulin class monomers is shown in Figure Ib .
- the classes differ in the composition and sequence of their respective heavy chains .
- Both IgM and IgE lack a hinge region but each contains an extra heavy-chain domain (CH4 ) .
- Numbers and locations of the disulfide bonds (lines ) linking the chains differ between the isotypes . They also differ in the distribution of N-linked carbohydrate groups , symbolically shown as circles .
- Each domain in an antibody molecule has a similar structure of two beta sheets packed tightly against each other in a compressed antiparallel beta barrel . This conserved structure is termed the immunoglobulin fold.
- the immunoglobulin fold of constant domains contains a 3-stranded sheet packed against a 4- stranded sheet . The fold is stabilized by hydrogen bonding between the beta strands of each sheet, by hydrophobic bonding between residues of opposite sheets in the interior, and by a disulfide bond between the sheets .
- the 3-stranded sheet comprises strands C, F, and G, and the 4-stranded sheet has strands A, B, E, and D .
- the letters A through G denote the sequential positions of the beta strands along the amino acid sequence of the immunoglobulin fold.
- the fold of variable domains has 9 beta strands arranged in two sheets of 4 and 5 strands .
- the 5-stranded sheet is structurally homologous to the 3-stranded sheet of constant domains , but contains the extra strands C and C f f .
- the remainder of the strands (A, B, C, D, E, F, G) have the same topology and similar structure as their counterparts in constant domain immunoglobulin folds .
- a disulfide bond links strands B and F in opposite sheets , as in constant domains .
- the immunoglobulin fold is illustrated in Figure 2 for a constant and a variable domain of an immunoglobulin .
- variable domains of both light and heavy immunoglobulin chains contain three hypervariable loops , or complementarity-determining regions (CDRs ) .
- the three CDRs of a V domain (CDRl , CDR2 , CDR3) cluster at one end of the beta barrel .
- the CDRs are loops that connect beta strands B-C, C -C 11 , and F-G of the immunoglobulin fold.
- the residues in the CDRs vary from one immunoglobulin molecule to the next, imparting antigen specificity to each antibody .
- the VL and VH domains at the tips of antibody molecules are closely packed such that the 6 CDRs (3 on each domain) cooperate in constructing a surface (or cavity) for antigen-specific binding .
- the natural antigen binding site of an antibody thus is composed of the loops which connect strands B-C, C -C ' , and F-G of the light chain variable domain and strands B-C, C -C ' , and F-G of the heavy chain variable domain .
- the basic principle of this technique is based on the observation that many proteins have a stable core, formed by specific arrangements of secondary structure elements such as beta sheets or alpha helices , which are interconnected by structures such as loops , turns , or random coils . Typically, these latter three structure elements are less crucial for the overall structure of the protein, and amino acid residues in these structure elements can be exchanged often without destroying the general fold of the protein .
- a naturally occurring example for this design prin- ciple are the CDRs of antibodies .
- Artificial examples include lipocalins , ankyrins and other protein scaffolds .
- the loops which are not CDR-loops in a native immunoglobulin do not have antigen binding or epitope binding specificity but contribute to the correct folding of the entire immunoglobulin molecule and/or its effector or other functions and are therefore called structural loops for the purpose of this invention .
- US Pat Appl 2004/0101905 describes binding molecules comprising a target binding site and a Fc effector peptide .
- the Fc effector peptide is a peptide which interacts with effector molecule .
- the insertion of an effector peptide into a non-CDR loop of a CHl-domain of an immunoglobulin fragment has been shown .
- Fc effector peptides are structures which are naturally occurring in non-CDR loops of antibodies and are therefore expected not to disturb the structure of the immunoglobulin if grafted to onto different equivalent locations in an immunoglobulin .
- every peptide grafted into a non-CDR loop according to this disclosure has a high chance of being inactive by the different structural environment it has been selected.
- the present invention relates to a method for engineering an immunoglobulin comprising at least one modification in a structural loop region of said immunoglobulin and determining the binding of said immunoglobulin to an epitope of an antigen, wherein the unmodified immunoglobulin does not significantly bind to said epitope, comprising the steps of :
- the present invention relates to a method for engineering an immunoglobulin binding specifically to an epitope of an antigen selected from the group consisting of allergens , tumor associated antigens , self antigens , enzymes , bacterial antigens , fungal antigens , protozooal antigen and viral antigens .
- an antigen selected from the group consisting of allergens , tumor associated antigens , self antigens , enzymes , bacterial antigens , fungal antigens , protozooal antigen and viral antigens .
- the immunoglobulin may be engineered bind to the epitope .
- the immunoglobulin is binding specifically to at least two such epitopes , that differ from each other, either of the same antigen or of different antigens .
- the method according to the invention refers to engineering an immunoglobulin binding specifically to at least one first epitope and comprising at least one modification in at least one structural loop region of said immunoglobulin and determining the specific binding of said at least one loop region to at least one second epitope, the epitope being selected from the group of antigens as mentioned above, wherein the unmodified structural loop region (non-CDR region) does not specifically bind to said at least one second epitope, comprising the steps of :
- the method according to the invention preferably refers to at least one modification in at least one structural loop region of said immunoglobulin and determining the specific binding of said at least one loop region to at least one antigen selected from the group consisting of allergens , tumor associated anti- gens , self antigens , enzymes , bacterial antigens , fungal antigens , viral antigens and protozooal antigens , wherein the immunoglobulin containing an unmodified structural loop region does not specifically bind to said at least one antigen .
- immunoglobulins may exhibit mono- or multi-specific, or multivalent binding properties , at least two, preferably at least three specific binding sites for epitopes of e . g . antigens , effector molecules/proteins .
- Immunoglobulins according to the invention are also functional fragments accepted in the art, such as Fc, Fab, scFv, single chain dimers of CH/CL domains , Fv, or other derivatives or combinations of the immunoglobulins , domains of the heavy and light chains of the variable region (such as Fd, Vl, Vk, Vh) and the constant region of an intact antibody such as CHl , CH2 , CH3, CH4 , Cl and Ck, as well as mini-domains consisting of two beta-strands of an immunoglobulin domain connected by a structural loop .
- immunoglobulin includes a derivative of immunoglobulins as well .
- a derivative is any combination of one or more immunoglobulins of the invention and or a fusion protein in which any domain or minidomain of the immunoglobulin of the invention may be fused at any position of one or more other proteins (such as other immunoglobulins , ligands , scaffold proteins , enzymes toxins and the like) .
- a derivative of the immunoglobulin of the invention may also be obtained by binding to other substances by various chemical techniques such as covalent coupling, electrostatic interaction, disulphide bonding etc .
- the other substances bound to the immunoglobulins may be lipids , carbohydrates , nucleic acids , organic and anorganic molecules or any combination therof (e . g . PEG, prodrugs or drugs ) .
- a derivative is also an immunoglobulin with the same amino acid sequence but made completely or partly from non-natural or chemically modified amino acids .
- the engineered molecules according to the present invention will be useful as stand-alone proteins as well as fusion proteins or derivatives , most typically fused in such a way as to be part of larger antibody structures or complete antibody mo- lecules , or parts thereof such as Fab fragments , Fc fragments , Fv fragments and others . It will be possible to use the engineered proteins to produce molecules which are monospecific, bis- pecific, trispecific, and maybe even carry more specificities at the same time, and it will be possible at the same time to control and preselect the valency of binding at the same time according to the requirements of the planned use of such molecules .
- binding regions to antigens or antigen binding sites of all kinds of allergens , tumor associated antigens , self antigens , enzymes , bacterial antigens , fungal antigens , protozooal antigen and viral antigens may be introduced into a structural loop of a given antibody structure .
- antigen shall mean molecules or structures known to interact or capable of interacting with the CDR-loop region of immunoglobulins .
- Structural loop regions of the prior art do not interact with antigens but rather contribute to the overall structure and/or to the binding to effector molecules .
- allergens , tumor associated antigens , self antigens , enzymes , bacterial antigens , fungal antigens , protozooal antigen and viral antigens
- allergens and antigens capable of being recognised by an antibody structure, and fragments of such molecules (especially substructures generally referred to as “epitopes” (e . g . B-cell epitopes ) ) , as long as they are immunologically relevant, i . e . are also recognisable by natural or monoclonal antibodies .

- a "structural loop” or “non-CDR-loop” is to be understood in the following manner : immunoglobulins are made of domains with a so called immunoglobulin fold. In essence, anti-parallel beta sheets are connected by loops to form a compressed antiparallel beta barrel . In the variable region, some of the loops of the domains contribute essentially to the specificity of the antibody, i . e . the binding to an antigen . These loops are called CDR-loops . All other loops of antibody domains are rather contributing to the structure of the molecule and/or the effector function . These loops are defined herein as structural loops or non-CDR-loops .

- selection methods When immunoglobulins libraries are screened using a selection method, only those members of a library that are favorable, that is which meet some selection criteria, are propagated, isolated, and/or observed. As will be appreciated, because only the most fit variants are observed, such methods enable the screening of libraries that are larger than those screenable by methods that assay the fitness of library members individually .
- Selection is enabled by any method, technique, or fusion partner that links , covalently or noncovalently, the phenotype of immunoglobulins with its genotype, that is the function of a antibody with the nucleic acid that encodes it .
- the use of phage display as a selection method is enabled by the fusion of library members to the gene III protein .
- selection or isolation of modified immunoglobulins that meet some criteria, for example binding affinity to the immunoglobulin ' s target also selects for or isolates the nucleic acid that encodes it .

- Another aspect of the present invention relates to a method for manufacturing an immunoglobulin or a pharmaceutical preparation thereof comprising at least one modification in a structural loop region of said immunoglobulin and determining the binding of said immunoglobulin to an epitope of an antigen, wherein the unmodified immunoglobulin does not significantly bind to said epitope, comprising the steps of :
- the present invention relates to a method for manufacturing a multi-specific immunoglobulin binding specifically to at least one first molecule or a pharmaceutical preparation thereof comprising at least one modification in at least one structural loop region of said immunoglobulin and determining the specific binding of said at least one loop region to at least one second molecule selected from the group consisting of allergens , tumor associated antigens , self antigens , enzymes , bacterial antigens , fungal antigens , protozooal antigens and viral antigens , wherein the immunoglobulin containing an unmodified structural loop region does not specifically bind to said at least one second molecule, comprising the steps of :
- bispecific antibodies made of two different polypeptide chains (heavy and light chain) is the necessity to express four different chains (two heavy and two light chains ) in one cell resulting in a number of various combinations of molecules which have to be separated from the desired bispecific molecule in the mixture . Due to their similarity the separation of these molecules is difficult and expensive . A number of techniques have been employed to minimize the occurrence of such unwanted pairings (Carter (2001 ) Journal of Immunological Methods , vol 248 , pages 7-15)
- bispecific antibodies Another problem of the current design of bispecific antibodies is the fact that even if the parent antibodies are bi- valently binding to their respective binding partner (e . g . IgG) , the resulting bispecific antibody is monovalent for each of the respective binding partner .
- their respective binding partner e . g . IgG
- the preferred multi-specific molecules of the present invention solve these problems :
- bispecific molecule as one polypeptide chain is possible (a modified Ig domain with two binding specificit- ies , see example section) , which is easier to accomplish than the expression of two antibody polypeptide chains (Cabilly et al . Proc . Natl . Acad. Sci . USA 81 : 3273-3277 (1984 ) ) .
- An antibody of the present invention may consist of a heavy- chain and a light chain, which form together a variable region binding to a specific binding partner the second specificity may be formed by a modified loop of any of the structural loops of either the heavy chain or the light chain .
- the binding site may also be formed by more than one non-CDR loop which may be structurally neighboured (either on the heavy chain or on the light chain or on both chains ) .
- the modified antibody or derivative may be a complete antibody or an antibody fragment (e . g . Fab, CH1-CH2 , CH2-CH3) .
- It may bind mono- or multi-valently to binding partners or even with different valency for the different binding partners , depending on the design .
- the specific binding domains within one polypeptide chain may be connected with or without a peptide linker .
- Some antibody classes can be regarded as multi-specific, in particular bispecific, by nature : They bind to an antigen (which is typically e . g . either a foreign structure or a cancer associated structure) with the variable region and bind to Fc-effector molecules with the Fc part (e . g . Fc receptors on various immune cells or complement protein) thus enabling effects such as ADCC, ADCP or CDC .
- an antigen which is typically e . g . either a foreign structure or a cancer associated structure
- Fc-effector molecules e e g . Fc receptors on various immune cells or complement protein
- the Fc-effector molecules are bound by the Fc-part of an immunoglobulin molecule (for IgGl it consists of domains CH2 and CH3) and a number of methods have been described to optimize effector function by improvement of binding of the Fc-part of an antibody molecule either by glycoengineering techniques (US 6, 602 , 684 ) or by protein engineering either directly at the Fc (US 2005/0054832 ) or indirectly by engineering outside the Fc (US 2005/02444403) . Both, binding of the Fc region to Fc receptor and/or binding to complement proteins such CqI has been altered by such techniques . Usually the binding affinity to such Fc-effector molecules is seeked to improve as this correlates with improved effector functions .
- Modified loops in antibody domains other than the loops involved in "natural" Fc-effector molecule binding can be selected from a library or designed to bind to one ore more Fc-effector molecule .
- An antibody with such additional Fc-effector molecule binding sites would either have stronger avidity to a certain Fc-effector molecule or effector-cell displaying an Fc- effector molecule and therefore may have an even stronger effect than glycoengineered antibodies or otherwise improved Fc regions .
- the effector characteristics of a given antibody to be modified should not directly be changed but remain unaffected by the modification in the structural loop according to the present invention .
- Antibody fragments have certain advantages as compared to whole antibodies . Fragments have usually good biodistribution properties and can more easily be produced. However, most of the antibody fragment designs lack effector functions and have short in vivo half life (Holliger P, et al . Nat Biotechnol . (2005) 23 : 1126-36. ) .
- the WO 02/44215 describes binding molecules which consists of the antigen binding site of an antibody and a peptide binding Fc-effector molecules . In such a way an antibody fragment displaying effector functions can be constructed.
- the peptide is being incorporated into the binding molecule at a position that does neither destroy the antigen binding nor the ability of the peptide to bind to an Fc-effector molecule .
- the binding to Fc-effector molecules may be performed with modified immuno- globulin domains which have been selected for Fc-effector molecule binding from libraries of random loop sequences within a fixed scaffold of an immunoglobulin domain . Therefore, it is possible to select for specific loop sequences which would not bind to Fc-effector molecules outside the Ig-domain scaffold.
- the polypeptides resulting from the present invention may therefore preferably consist of more than 100 amino acids .
- libraries of mutant CHl , CK or C ⁇ domains may be selected for binding to Fc-receptors and/or complement factors such as CIq.
- binding to FcRn may be selected for with libraries of mutant e . g . CHl-, CH2-, CH3-, CH4-, CK- or C ⁇ -domains according to the present invention .
- FcRn-receptors for selection may be provided either on the surface of cells expressing naturally the respective receptors or by expression and purification of the extracellular part of the respective receptor .
- a first screening on FcRn may select for mutant domains which can further be tested in vitro and even further characterized in FACS experiments by binding to cells expressing FcRn receptor . It can be further characterized by affinity ranking of binding to various recombinant FcRn, isoforms and allotypes e . g with surface plasmon resonance techniques .

Of course also the order of the single domains may be of any kind (e.g. CH1-CH3-CH2, CH4-CH1-CH3-CH2) .

- Another aspect of the present invention relates to a method for specifically isolating a molecule comprising the steps of :
- the immunoglobulins according to the present invention may be used to isolate specifically molecules from a sample . If multi-specific immunoglobulins are used more than one molecules may be isolated from a sample . It is especially advantageous using modified immunoglobulins in such methods because it allows , e . g . , to generate a matrix having a homogeneous surface with defined amounts of binding partners (i . e . Modified immunoglobulins ) immobilised thereon which able to bind to the molecules to be isolated. In contrast thereto, if mono-specific binding partners are used no homogeneous matrix can be generated because the single binding partners do not bind with the same efficiency to the matrix .
- Another aspect of the present invention relates to a method for targeting a compound to a target comprising the steps of :
- Modified immunoglobulins according to the present invention may be used to deliver at least one compound bound to the CDRs and/or modified loop regions to a target .
- Such immunoglobulins may be used to target therapeutic substances to a preferred site of action in the course of the treatment of a disease .

- the library according to the present invention may be used to identify immunoglobulins binding to a distinct molecule .
- the present invention relates to the use of a protein library comprising an immunoglobulin according to the present invention or obtainable by the method according to the present invention for the design of immunoglobulin derivatives .
- An existing immunoglobulin can be changed to introduce antigen binding sites into any domain or minidomain by using a protein library of the respective domain of at least 10 , preferably 100 , more preferably 1000 , more preferably 10000 , more preferably 100000 , most preferably more than 1000000 variant domains with at least one modified loop .
- the library is then screened for binding to the specific antigen .
- the selected domain or minidomain is cloned into the original immunoglobulin by genetic engineering techniques so that it replaces the wild type region .
- only the DNA coding for the loops or coding for the mutated amino acids may be exchanged to obtain an immunoglobulin with the additional binding site for the specific antigen .
- the choice of the site for the mutated, antigen-specific structural loop is dependent on the structure of the original immunoglobulin and on the purpose of the additional binding site . If, for example, the original molecule is a complete immunoglobulin which needs to have inserted an additional antigen binding site without disturbance of the effector function, the loops to be modified would be selected from domains distant from CH2 and CH3 which are the natural binding partners to Fc-effect- or molecules . If the original immunoglobulin is a Fab, modification of loops in constant domains of the light chains or the heavy chains or the respective variable domains is possible . To generate a library one may prepare libraries of mutant original molecules which have mutations in one ore more structural loops of one or more domains . The selection with complete mutated original molecules may have some advantages as the selection for antigen binding with a modified structural loop will deliver the sterically advantageous modifications if tested also for the other properties the mutated immunoglobulin should show .
- the size requirement (i . e . the number of variant proteins ) of a protein library of a mutated domain or a minidomain or a fusion molecule of a domain is dependent on the task .
- a library to generate an antigen binding site de novo needs to be larger than a library used to further modify an already existing engineered antigen binding site made of a modified structural loop (e . g . for enhancing affinity or changing fine specificity to the antigen) .

This means that a binding partner, such as a Fc-receptor or an effector of the immune system, is not considered to be bound by the antigen binding site foreign to the unmodified immunoglobulin .

- Percent (%) amino acid sequence identity with respect to the immunoglobulin domain sequences identified herein is defined as the percentage of amino acid residues in a candidate sequence that are identical with the amino acid residues in the specific immunoglobulin domain sequence, after aligning the sequence and introducing gaps , if necessary, to achieve the maximum percent sequence identity, and not considering any conservative substitutions as part of the sequence identity . Alignment for purposes of determining percent amino acid sequence identity can be achieved in various ways that are within the skill in the art, for instance, using publicly available computer software such as BLAST, BLAST-2 , ALIGN or Megalign (DNASTAR) software . Those skilled in the art can determine appropriate parameters for measuring alignment, including any algorithms needed to achieve maximal alignment over the full length of the sequences being compared.
- a % amino acid sequence identity value is determined by dividing (a) the number of matching identical amino acid residues between the amino acid sequence of the immunoglobulin domain of interest having a sequence derived from the native immunoglobulin domain and the comparison amino acid sequence of interest (i . e . , the sequence against which the immunoglobulin domain of interest is being compared which may be the unmodified immunoglobulin domain) as determined by WU-BLAST-2 by (b) the total number of amino acid residues of the non-randomized parts of the immunoglobulin do- main of interest .

- one of the key features of the present invention is that the engineering of the immunoglobulin domains takes place in regions which are not normally involved in antigen binding, in other words , in regions other than the CDRs of an antibody . It was observed that the specific fold of immunoglobulin domains allows the introduction of random mutations in regions which are structurally analogous to the CDRs but different in position in sequence .
- the regions identified by the present invention are, like CDRs , loop regions connecting the beta strands of the immunoglobulin fold.
- immunoglobulin domains from any class of immunoglobulins and from immunoglobulins from any species are amenable to this type of engineering .
- the specific loops targeted in the present invention can be manipulated, but any loop connecting beta strands in immunoglobulin domains can be manipulated in the same way .
- Engineered immunoglobulin domains from any organism and from any class of immunoglobulin can be used according to the present invention either as such (as single domains ) , or as part of a larger molecule .
- they can be part of an intact immunoglobulin, which accordingly would have its "normal" antigen binding region formed by the 6 CDRs and the new, engineered antigen binding region .

- Single immunoglobulin domains randomized on one side, i . e . either in loops connecting beta-strands B-C, D-E or F-G (the "tip” , with the exception of variable domains which are covered by many patents ) or beta-strands A-B, C-D, (C-C and C ' -D in the case of variable domains ) or E-F (the "bottom” ) .

- the primary advantages of the single domains are very similar to all the arguments that are used to promote camel VH molecules ( "nanobodies " , see www . ablynx . com) .
- the randomized immunoglobulin domains are very small proteins (molecular weight ca . 12-15 kDa, depending on the number of inserted amino acid residues ) and therefore will have the following advantages as compared to conventional antibodies or antibody fragments such as scFv and Fabs : recognizing uncommon or hidden epitopes , binding into cavities or active sites of protein targets , ease of manufacture, and many others .
- a bivalent or a bispe- cific molecule can be generated.
- the main advantages of the single domains as part of fusion proteins is additional binding properties can be engineered on any other protein .
- any expression system can be used to make the proteins .
- An analogy to the single domains as described here can be found in the antibodies from the camel, which only has a VH but no VL In these proteins , only 3 CDRs (instead of 6 as in "normal" antibodies are responsible for antigen binding) .
