## Title
Siglec-15 antibodies in treating bone loss-related disease

## Abstract

Novel antibodies and antigen binding fragments that specifically binds to Siglec-15 are described herein. In some embodiments, the antibodies or antigen binding fragments may block the biological activity of Siglec-15 and are useful in composition for the treatment of bone loss, more particularly in bone diseases that have increased cell surface expression of Siglec-15, such as conditions where there is an increase in the bone degradative activity of osteoclasts. The invention also relates to cells expressing the antibodies or antigen binding fragments such as monoclonal, humanized or chimeric antibodies. Additionally, methods of detecting and treating bone loss, bone-related diseases or cancer using the antibodies and fragments are also disclosed.

## Background
FIELD OF THE INVENTION
The present invention relates to monoclonal antibodies and antigen binding fragments thereof that specifically bind to Siglec-15 and their use for treating certain diseases including diagnosing, preventing and treating cancer or bone loss, such as severe or excessive bone loss associated with bone-related diseases or associated with an increase in osteoclast differentiation or activity. The present invention also relates to the use of these antibodies for diagnosis, prevention and treatment of various other types of diseases where the activity of osteoclasts is increased.
BACKGROUND OF THE INVENTION
Bone is a dynamic connective tissue comprised of functionally distinct cell populations required to support the structural, mechanical and biochemical integrity of bone and the human body's mineral homeostasis. The principal cell types involved include, osteoblasts responsible for bone formation and maintaining bone mass, and osteoclasts responsible for bone resorption. Osteoblasts and osteoclasts function in a dynamic process termed bone remodelling. The development and proliferation of these cells from their progenitors is governed by networks of growth factors and cytokines produced in the bone microenvironment as well as by systemic hormones. Bone remodelling is ongoing throughout the lifetime of the individual and is necessary for the maintenance of healthy bone tissue and mineral homeostasis. The process remains largely in equilibrium and is governed by a complex interplay of systemic hormones, peptides and downstream signalling pathway proteins, local transcription factors, cytokines, growth factors and matrix remodelling genes.
Any interference or imbalance arising in the bone remodelling process can produce skeletal disease, with the most common skeletal disorders characterized by a net decrease in bone mass. A primary cause of this reduction in bone mass is an increase in osteoclast number and/or activity. The most common of such disease, and perhaps the best known, is osteoporosis occurring particularly in women after the onset of menopause. In fact osteoporosis is the most significant underlying cause of skeletal fractures in late middle-aged and elderly women. While estrogen deficiency has been strongly implicated as a factor in postmenopausal osteoporosis, there is longstanding evidence that remodelling is a locally controlled process being that it takes place in discrete packets throughout the skeleton as first described by Frost over forty years ago (Frost H. M. 1964).
Since bone remodelling takes place in discrete packets, locally produced hormones and enzymes may be more important than systemic hormones for the initiation of bone resorption and the normal remodelling process. Such local control is mediated by osteoblasts and osteoclasts in the microenvironment in which they operate. For example, osteoclasts attach to the bone matrix and form a separate compartment between themselves and the bone surface delimited by a sealing zone formed by a ring of actin surrounding the ruffled border. Multiple small vesicles transport enzymes toward the bone matrix and internalize partially digested bone matrix. The microenvironment within the sealing zone is rich with the presence of lysosomal enzymes and is highly acidic compared to the normal physiological pH of the body. The ruffled border membrane also expresses RANK, the receptor for RANKL, and macrophage-colony stimulating factor (M-CSF) receptor, both of which are responsible for osteoclast differentiation, as well as the calcitonin receptor capable of rapidly inactivating the osteoclast (Baron, R. 2003).
In a complex pattern of inhibition and stimulation, growth hormone, insulin-like growth factor-1, the sex steroids, thyroid hormone, calciotrophic hormones such as PTH and prostaglandin E2, various cytokines, such as interleukin-1 beta, interleukin-6, and tumor necrosis factor-alpha, and 1,25-dihydroxyvitamin D (calcitriol) act co-ordinately in the bone remodelling process (Jilka et al. 1992; Poli et al. 1994; Srivastava et al. 1998; de Vemejoul 1996).
Thus, it stands to reason that the unique local environments created by these specialized cells is due to the expression of either unique genetic sequences not expressed in other tissues and/or splice variants of polynucleotides and polypeptides expressed in other tissues. The isolation and identification of polynucleotides, polypeptides and their variants and derivatives specific to osteoclast activity will permit a clearer understanding of the remodelling process and offer tissue specific therapeutic targets for the treatment of disease states related to bone remodelling.
Many diseases linked to bone remodelling are poorly understood, generally untreatable or treatable only to a limited extent. For example, osteoarthritis is difficult to treat as there is no cure and treatment focuses on relieving pain and preventing the affected joint from becoming deformed. Non-steroidal anti-inflammatory drugs (NSAIDs) are generally used to relieve pain.
Another example is osteoporosis where the only current medications approved by the FDA for use in the United States are the anti-resorptive agents that prevent bone breakdown. Estrogen replacement therapy is one example of an anti-resorptive agent. Others include alendronate (Fosamax—a biphosphonate anti-resorptive), risedronate (Actonel—a bisphosphonate anti-resorptive), raloxifene (Evista—selective estrogen receptor modulator (SERM)), calcitonin (Calcimar—a hormone), and parathyroid hormone/teriparatide (Forteo—a synthetic version of the human hormone, parathyroid hormone, which helps to regulate calcium metabolism).
Bisphosphonates such as alendronate and risedronate bind permanently to the surface of bone and interfere with osteoclast activity. This allows the osteoblasts to outpace the rate of resorption. The most common side effects are nausea, abdominal pain and loose bowel movements. However, alendronate is reported to also cause irritation and inflammation of the esophagus, and in some cases, ulcers of the esophagus. Risedronate is chemically different from alendronate and has less likelihood of causing esophagus irritation. However, certain foods, calcium, iron supplements, vitamins and minerals, or antacids containing calcium, magnesium, or aluminum can reduce the absorption of risedronate, thereby resulting in loss of effectiveness.
The most common side effect of Raloxifen and other SERMS (such as Tamoxifen) are hot flashes. However, Raloxifene and other hormone replacement therapies have been shown to increase the risk of blood clots, including deep vein thrombosis and pulmonary embolism, cardiovascular disease and cancer.
Calcitonin is not as effective in increasing bone density and strengthening bone as estrogen and the other anti-resorptive agents. Common side effects of either injected or nasal spray calcitonin are nausea and flushing. Patients can develop nasal irritations, a runny nose, or nosebleeds. Injectable calcitonin can cause local skin redness at the site of injection, skin rash, and flushing.
A situation demonstrative of the link between several disorders or disease states involving bone remodelling is that of the use of etidronate (Didronel) first approved by the FDA to treat Paget's disease. Paget's disease is a bone disease characterized by a disorderly and accelerated remodelling of the bone, leading to bone weakness and pain. Didronel has been used ‘off-label’ and in some studies shown to increase bone density in postmenopausal women with established osteoporosis. It has also been found effective in preventing bone loss in patients requiring long-term steroid medications (such as Prednisone or Cortisone). However, high dose or continuous use of Didronel can cause another bone disease called osteomalacia. Like osteoporosis, osteomalacia can lead to weak bones with increased risk of fractures. Because of osteomalacia concerns and lack of enough studies yet regarding reduction in the rate of bone fractures, the United States FDA has not approved Didronel for the treatment of osteoporosis.
Osteoporosis therapy has been largely focused on antiresorptive drugs that reduce the rate of bone loss but emerging therapies show promise in increasing bone mineral density instead of merely maintaining it or slowing its deterioration. The osteoporosis early stage pipeline consists largely of drug candidates in new therapeutic classes, in particular cathepsin K inhibitors, osteoprotegerin and calcilytics as well as novel bisphosphonates. Some of these are examples where novel drugs exploiting genomics programs are being developed based on a deeper understanding of bone biology and have the potential to change the face of treatment of bone disorders in the long term.
The present invention describes the use of antibodies specific for Siglec-15 for the diagnosis, prognosis, and treatment (including prevention) of cancer or bone loss (e.g., severe or excessive bone loss associated with bone-related disease or associated with an increase in osteoclast differentiation or activity). In particular, the present invention relates to the use of anti-Siglec-15 antibodies for inhibiting the differentiation of osteoclasts.
Sialic-acid-binding immunoglobulin-like lectins (Siglecs) are members of the immunoglobulin (Ig) superfamily that have the ability to interact with sialic acids (McMillan and Crocker, 2008; Crocker et al., 2007). There are several Siglec family members that all share specific structural features, in particular, displaying an amino-terminal V-set Ig domain that binds to sialic acid and a variable number of C2-set Ig domains. These membrane receptors are generally expressed in highly specific manners and many of the family members are expressed in hematopoietic cells (McMillan and Crocker, 2008). These proteins are thought to promote cell-cell interactions, mediate signalling, and regulate immune functions through the recognition of glycans (Crocker et al., 2007). Sialic acids are nine-carbon sugars typically located at the ends of complex glycoconjugates on the surface of cells. They can be attached to a wide variety of proteins and lipids (McMillan and Crocker, 2008).
Siglec-15 is one of the most recently described Siglec family members that have a high homology to Siglec-14 (Angata et al., 2007). These authors reported that it preferentially binds to sialyl Tn structure and that it interacts with DAP12 and DAP10. The functional significance of these interactions is not known but it was proposed that Siglec-15 probably harbors an activating function (Angata et al., 2007). Despite these preliminary insights into a potential role in mammals of Siglec-15, important advances in the understanding of the biological function of the protein were contributed when the sequence was identified as part of a screen to discover novel regulators of osteoclast differentiation (Sooknanan et al. 2007). In this patent application, it was revealed that attenuation of the Siglec-15 transcript by RNA interference in a mouse model of osteoclastogenesis resulted in significant reduction of differentiation of precursors in response to RANKL treatment. Similar results were disclosed in human osteoclasts. Furthermore, the studies presented in this disclosure also showed that the localization of Siglec-15 at the cell membrane was necessary for its function in osteoclast differentiation. Furthermore, a recent publication showed that the presence of sialic acid at the end of surface glycoconjugates was required for proper osteoclast differentiation and were probably important for the fusion of osteoclast precursor cells (Takahata et al., 2007). This last observation creates a direct functional link between sialic acid binding and the expression of Siglec-15 in differentiating osteoclasts and strongly suggested that Siglec-15 plays a role in the early differentiation program of osteoclast precursors.
Thus, the expression profile of Siglec-15, its strong inducibility during osteoclast differentiation, its localization at the surface of the membrane, and its structural features all contribute to the feasibility of targeting this protein at the cell surface with monoclonal antibodies. The only other example of monoclonal antibody-based therapy that target osteoclasts is denosumab, a human monoclonal antibody that is specific for RANKL (Ellis et al. 2008). The present invention relates to the use of anti-Siglec-15 antibodies or antigen binding fragments as blockers of osteoclast differentiation in the detection or treatment of bone loss, especially in the context of bone-related diseases or in the context of increased osteoclast differentiation or activity. The present invention also relates to the use of antibodies or antigen binding fragments in the detection or treatment of cancer.

The term “antibody” refers to intact antibody, monoclonal or polyclonal antibodies. The term “antibody” also encompasses, multispecific antibodies such as bispecific antibodies. Human antibodies are usually made of two light chains and two heavy chains each comprising variable regions and constant regions.

The heavy chain variable region comprises 3 CDRs, identified herein as CDRH1, CDRH2 and CDRH3 flanked by framework regions.
The term “antigen-binding fragment”, as used herein, refers to one or more fragments of an antibody that retain the ability to bind to an antigen (e.g., SEQ ID NO:2 or variants thereof). It has been shown that the antigen-binding function of an antibody can be performed by fragments of an intact antibody. Examples of binding fragments encompassed within the term “antigen-binding fragment” of an antibody include (i) a Fab fragment, 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), e.g., VH CDR3. Furthermore, although the two domains of the Fv fragment, VL and VH, are coded for by separate genes, they can be joined, using recombinant methods, by a synthetic linker that enables them to be made as a single polypeptide 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” of an antibody. Furthermore, the antigen-binding fragments include binding-domain immunoglobulin fusion proteins comprising (i) a binding domain polypeptide (such as a heavy chain variable region, a light chain variable region, or a heavy chain variable region fused to a light chain variable region via a linker peptide) that is fused to an immunoglobulin hinge region polypeptide, (ii) an immunoglobulin heavy chain CH2 constant region fused to the hinge region, and (iii) an immunoglobulin heavy chain CH3 constant region fused to the CH2 constant region. The hinge region may be modified by replacing one or more cysteine residues with serine residues so as to prevent dimerization. Such binding-domain immunoglobulin fusion proteins are further disclosed in US 2003/0118592 and US 2003/0133939. These antibody fragments are obtained using conventional techniques known to those with skill in the art, and the fragments are screened for utility in the same manner as are intact antibodies.
A typical antigen binding site is comprised of the variable regions formed by the pairing of a light chain immunoglobulin and a heavy chain immunoglobulin. The structure of the antibody variable regions is very consistent and exhibits very similar structures. These variable regions are typically comprised of relatively homologous framework regions (FR) interspaced with three hypervariable regions termed Complementarity Determining Regions (CDRs). The overall binding activity of the antigen binding fragment is often dictated by the sequence of the CDRs. The FRs often play a role in the proper positioning and alignment in three dimensions of the CDRs for optimal antigen binding.
Antibodies and/or antigen binding fragments of the present invention may originate, for example, from a mouse, a rat or any other mammal or from other sources such as through recombinant DNA technologies.
Further scope, applicability and advantages of the present invention will become apparent from the non-restrictive detailed description given hereinafter. It should be understood, however, that this detailed description, while indicating exemplary embodiments of the invention, is given by way of example only, with reference to the accompanying drawings.
DETAILED DESCRIPTION OF THE INVENTION
The Expression Profile of Siglec-15 in Osteoclasts and Normal Tissues
The present invention relates to the use of monoclonal antibodies to target osteoclasts found in various bone related disease where severe bone loss is observed due to increased activity of the osteoclasts. In order to direct the antibodies to the osteoclasts, the identification of osteoclast-specific antigens that are expressed at the cell surface of the cells must be carried out. There are several technologies that are available to identify cell-specific antigens and the method that was used to identify Siglec-15 in differentiating osteoclasts that were treated with RANKL, an innovative discovery platform called Subtractive Transcription-based Amplification of mRNA (STAR), is described in the published patent application No. PCT/CA2007/000210.
Analysis of the human osteoclast STAR libraries yielded many genes that encode secreted and cell surface proteins. One of these, termed AB-0326, contained an open reading frame that encoded a polypeptide of 328 amino acids, corresponding to SEQ ID NO:2 that was encoded by a cDNA of 987 base pairs with the nucleotide sequence shown in SEQ ID NO:1. A search of publicly available databases revealed that the AB-0326 nucleotide sequence was identical to that of a human gene called CD33 antigen-like 3 (CD33L3). CD33L3 was later found to be a member of the Siglec family of sialic acid binding proteins and was renamed Siglec-15 based on homology to other Siglecs (Crocker et al., 2007). Based on this information, the mouse orthologue was isolated and sequenced and found to be approximately 85% identical to the human sequence at the amino acid level. SEQ ID NO:3 and SEQ ID NO:4 show the sequences of cDNA and polypeptide of the murine Siglec-15, respectively. Bioinformatic analysis predicted a type I membrane-anchored protein that presents its functional domain to the extracellular compartment. As with other Siglec sequences, an amino-terminal signal peptide (located between amino acids 1 and 19 of SEQ ID NO:2) targets the protein to the membrane of cells and the final processed protein is anchored to the membrane via a single trans-membrane helix located at the carboxy-terminus (located between amino acids 261 and 283 of SEQ ID NO:2). The V-set Ig domain is located between amino acids 49 and 165 of SEQ ID NO:2 whereas the C2-set Ig domain is located between amino acids 178 and 244 of SEQ ID NO:2.
The present invention relates to the function of Siglec-15 during the differentiation of osteoclasts. Previous findings (Sooknanan et al. 2007) established that the transcript encoding human Siglec-15 was significantly upregulated in response to RANKL. This determination was performed on RNA macroarrays that contained spotted total RNA samples from several different human osteoclast differentiation experiments from different human PBMNC donors. Furthermore, these studies (Sooknanan et al. 2007) revealed that the Siglec-15 transcript was expressed in only one normal tissue among a vast panel of 30 human normal tissues indicating a very high osteoclast specificity of the Siglec-15 gene expression. Using more sensitive methods such as semi-quantitative RT-PCR, the expression of the Siglec-15 mRNA was stimulated within one day of RANKL treatment in many osteoclast samples indicating that the gene was expressed early in osteoclast precursor cells, prior to the commencement of cell fusion. Finally, the tissue expression profile of Siglec-15 was assessed by semi-quantitative RT-PCR and found to only be expressed in a single normal human tissue thus validating the macroarray results of Sooknanan et al. Taken together, these expression results underscore the strength of the Applicant's discovery approach in its ability to identify targets, as exemplified by Siglec-15, that are highly restricted to differentiating osteoclasts.
Based on the expression of Siglec-15 in the early stages of differentiation of osteoclasts, its limited expression in normal tissues, and a critical biological role for Siglec-15 in the activity of osteoclasts, Siglec-15 was chosen as a therapeutic target for the development of monoclonal antibodies for the detection, prevention, and treatment of bone-related diseases such as cancer-induced bone loss and osteoporosis.
Therefore, a variety of anti-Siglec-15 antibodies and immunologically functional fragments thereof, such as chimeric and humanized monoclonal antibodies, antibody fragments, single chain antibodies, domain antibodies, and polypeptides with an antigen-binding region, for targeting Siglec-15 are provided.
SEQ ID NO:2 as Antigen and Epitopes Derived from SEQ ID NO:2
In international application No. PCT/CA2007/000210, the Applicant has come to the unexpected discovery that SEQ ID NO:2 is involved in osteoclast differentiation. This antigen may thus be useful for targeting cells expressing the antigen in vitro or in vivo and in the development of detection assays for measuring the antigen in vitro or in vivo.

Antibodies and Antigen Binding Fragments that Binds to SEQ ID NO:2 or to SEQ ID NO:2 Variant
Antibodies were initially isolated from Fab libraries for their specificity towards the antigen of interest. Comparison of the amino acid sequences of the light chain variable domains or the heavy chain variable domains of antibodies showing the greatest characteristics allowed us to derive consensus sequences within the CDRs and within the variable regions. The consensus for CDRs are provided in SEQ ID Nos:148-158 and 197-210. The consensus for the variable regions are provided in SEQ ID Nos.:191-196.
The variable regions described herein may be fused with constant regions of a desired species thereby allowing recognition of the antibody by effector cells of the desired species. The constant region may originate, for example, from an IgG1, IgG2, IgG3, or IgG4 subtype. Cloning or synthesizing a constant region in frame with a variable region is well within the scope of a person of skill in the art and may be performed, for example, by recombinant DNA technology.
In certain embodiments of the present invention, antibodies that bind to SEQ ID NO:2 may be of the IgG1, IgG2, IgG3, or IgG4 subtype. More specific embodiments of the invention relates to an antibody of the IgG1 subtype. The antibody may be a humanized antibody of the IgG1 subtype that is biologically active in mediating antibody-dependent cellular cytotoxicity (ADCC), complement-mediated cytotoxicity (CMC), or associated with immune complexes. The typical ADCC involves activation of natural killer (NK) cells and is reliant on the recognition of antibody-coated cells by Fc receptors on the surface of the NK cells. The Fc receptors recognize the Fc domain of antibodies such as is present on IgG1, which bind to the surface of a target cell, in particular a bone cell that expresses an antigen, such as SEQ ID NO:2. Once bound to the Fc receptor of IgG the NK cell releases cytokines and cytotoxic granules that enter the target cell and promote cell death by triggering apoptosis.
The present invention described a collection of antibodies that bind to SEQ ID NO:2. In certain embodiments, the antibodies may be selected from the group consisting of polyclonal antibodies, monoclonal antibodies such as chimeric or humanized antibodies, antibody fragments such as antigen binding fragments, single chain antibodies, domain antibodies, and polypeptides with an antigen binding region.

Antibodies that Bind to Siglec-15

In certain embodiments of the present invention, antibodies that bind to Siglec-15 are of the IgG1, IgG2, IgG3, or IgG4 subtype. In the preferred embodiment, the antibody is an antibody of the IgG2 subtype. In the present embodiment, the antibody is a humanized antibody of the IgG2 subtype that is biologically active in blocking the biological activity of normal Siglec-15 function on the surface of osteoclasts. Such blockage, for example, could prevent the association of Siglec-15 with its substrates, its ligands, itself, or other proteins on adjacent cells.
The present invention discloses a collection of antibodies that bind to Siglec-15. In certain embodiments, the antibodies consist of monoclonal antibodies and immunologically functional fragments thereof, such as chimeric and humanized monoclonal antibodies, antibody fragments, single chain antibodies, domain antibodies, and polypeptides with an antigen-binding region.
A typical antigen-binding site is comprised of the variable regions formed by the pairing of a light chain immunoglobulin and a heavy chain immunoglobulin. The structure of the antibody variable regions is very consistent and exhibits very similar structures. These variable regions are typically comprised of relatively homologous framework regions (FR) interspaced with three hypervariable regions termed Complementarity Determining Regions (CDRs). Although the overall binding activity of the antigen binding fragment is dictated by the sequence of the CDRs, the FRs play a critical role in the proper positioning and alignment in three dimensions of the CDRs for optimal antigen binding.
Table 1 discloses the sequences of the nucleotides and the amino acids corresponding to the complete light and heavy chain immunoglobulins of specific examples of anti-Siglec-15 antibodies.

Variant Antibody and Antigen Binding Fragments
The present invention also encompasses variants of the antibodies or antigen binding fragments described herein. Variant antibodies or antigen binding fragments included are those having a variation in the amino acid sequence. For example, variant antibodies or antigen binding fragments included are those having at least one variant CDR (two, three, four, five, six and up to twelve variant CDRs), a variant light chain variable domain, a variant heavy chain variable domain, a variant light chain and/or a variant heavy chain. Variant antibodies or antigen binding fragments included in the present invention are those having, for example, similar or improved binding affinity in comparison with the original antibody or antigen binding fragment.
As used herein the term “variant” applies to any of the sequence described herein and includes for example, a variant CDR (either CDRL1, CDRL2, CDRL3, CDRH1, CDRH2 and/or CDRH3), a variant light chain variable domain, a variant heavy chain variable domain, a variant light chain, a variant heavy chain, a variant antibody, a variant antigen binding fragment and a SEQ ID NO.:2 variant.
Variant antibodies or antigen binding fragments encompassed by the present invention are those which may comprise an insertion, a deletion or an amino acid substitution (conservative or non-conservative). These variants may have at least one amino acid residue in its amino acid sequence removed and a different residue inserted in its place.
The sites of greatest interest for substitutional mutagenesis include the hypervariable regions (CDRs), but modifications in the framework region or even in the constant region are also contemplated. Conservative substitutions may be made by exchanging an amino acid (of a CDR, variable chain, antibody, etc.) from one of the groups listed below (group 1 to 6) for another amino acid of the same group.
Generally, mutations in the CDRs may have a greater impact on the antigen binding activity of the antibody or antigen binding fragment than mutations in the framework region. Variant antibody or antigen binding fragments that are encompassed by the present invention are those which have a substantially identical antigen binding capacity (including similar, identical, or slightly less) to those presented herein or have a better antigen binding capacity than those presented herein.
Other exemplary embodiment of conservative substitutions are shown in Table 1A under the heading of “preferred substitutions”. If such substitutions result in a undesired property, then more substantial changes, denominated “exemplary substitutions” in Table 1A, or as further described below in reference to amino acid classes, may be introduced and the products screened.
It is known in the art that variants may be generated by substitutional mutagenesis and retain the biological activity of the polypeptides of the present invention. These variants have at least one amino acid residue in the amino acid sequence removed and a different residue inserted in its place. For example, one site of interest for substitutional mutagenesis may include a site in which particular residues obtained from various species are identical. Examples of substitutions identified as “conservative substitutions” are shown in Table 1A. If such substitutions result in a change not desired, then other type of substitutions, denominated “exemplary substitutions” in Table 1A, or as further described herein in reference to amino acid classes, are introduced and the products screened.
Substantial modifications in function or immunological identity are accomplished by selecting substitutions that differ significantly in their effect on maintaining (a) the structure of the polypeptide backbone in the area of the substitution, for example, as a sheet or helical conformation. (b) the charge or hydrophobicity of the molecule at the target site, or (c) the bulk of the side chain. Naturally occurring residues are divided into groups based on common side chain properties:

    
    
        (group 1) hydrophobic: norleucine, methionine (Met), Alanine (Ala), Valine (Val), Leucine (Leu), Isoleucine (Ile)
        (group 2) neutral hydrophilic: Cysteine (Cys), Serine (Ser), Threonine (Thr)
        (group 3) acidic: Aspartic acid (Asp), Glutamic acid (Glu)
        (group 4) basic: Asparagine (Asn), Glutamine (Gln), Histidine (His), Lysine (Lys), Arginine (Arg)
        (group 5) residues that influence chain orientation: Glycine (Gly), Proline (Pro); and
        (group 6) aromatic: Tryptophan (Trp), Tyrosine (Tyr), Phenylalanine (Phe)

Non-conservative substitutions will entail exchanging a member of one of these classes for another.

Variation in the amino acid sequence of the variant antibody or antigen binding fragment may include an amino acid addition, deletion, insertion, substitution etc., one or more modification in the backbone or side-chain of one or more amino acid, or an addition of a group or another molecule to one or more amino acids (side-chains or backbone).
Variant antibody or antigen binding fragment may have substantial sequence similarity and/or sequence identity in its amino acid sequence in comparison with that of the original antibody or antigen binding fragment amino acid sequence. The degree of similarity between two sequences is based upon the percentage of identities (identical amino acids) and of conservative substitution.
Generally, the degree of similarity and identity between variable chains has been determined herein using the Blast2 sequence program (Tatiana A. Tatusova, Thomas L. Madden (1999), “Blast 2 sequences—a new tool for comparing protein and nucleotide sequences”, FEMS Microbiol Lett. 174:247-250) using default settings, i.e., blastp program, BLOSUM62 matrix (open gap 11 and extension gap penalty 1; gapx dropoff 50, expect 10.0, word size 3) and activated filters.
Percent identity will therefore be indicative of amino acids which are identical in comparison with the original peptide and which may occupy the same or similar position.
Percent similarity will be indicative of amino acids which are identical and those which are replaced with conservative amino acid substitution in comparison with the original peptide at the same or similar position.
Variants (i.e., analogues) of the present invention (including VL variants, VH variants, CDR variants, antibody variants, polypeptide variants, etc.) therefore comprise those which may have at least 70%, 75%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% sequence identity with an original sequence or a portion of an original sequence.
In accordance with the present invention, a SEQ ID NO.:2 variant includes a polypeptide having a region at least 80% identical with amino acids 49-165 or with amino acids 20 to 259 of SEQ ID NO.:2. Variants of SEQ ID NO.:2 also include polypeptides having at least 80% sequence identity with SEQ ID NO.:2.
Exemplary embodiments of variants are those having at least 81% sequence identity to a sequence described herein and 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% sequence similarity with an original sequence or a portion of an original sequence.
Other exemplary embodiments of variants are those having at least 82% sequence identity to a sequence described herein and 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% sequence similarity with an original sequence or a portion of an original sequence.
Further exemplary embodiments of variants are those having at least 85% sequence identity to a sequence described herein and 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% sequence similarity with an original sequence or a portion of an original sequence.

Production of the Antibodies in Cells
The antibodies that are disclosed herein can be made by a variety of methods familiar to those skilled in the art, such as hybridoma methodology or by recombinant DNA methods.
In an exemplary embodiment of the invention, the antibodies may be produced by the conventional hybridoma technology, where a mouse is immunized with an antigen, spleen cells isolated and fused with myeloma cells lacking HGPRT expression and hybrid cells selected by hypoxanthine, aminopterin and thymine (HAT) containing media.
In an additional exemplary embodiment of the invention, the antibodies may be produced by recombinant DNA methods.
In order to express the antibodies, nucleotide sequences able to encode any one of a light and heavy immunoglobulin chains described herein may be inserted into an expression vector, i.e., a vector that contains the elements for transcriptional and translational control of the inserted coding sequence in a particular host. These elements may include regulatory sequences, such as enhancers, constitutive and inducible promoters, and 5′ and 3′ un-translated regions. Methods that are well known to those skilled in the art may be used to construct such expression vectors. These methods include in vitro recombinant DNA techniques, synthetic techniques, and in vivo genetic recombination.
A variety of expression vector/host cell systems known to those of skill in the art may be utilized to express a polypeptide or RNA derived from nucleotide sequences able to encode any one of a light and heavy immunoglobulin chains described herein. These include, but are not limited to, microorganisms such as bacteria transformed with recombinant bacteriophage, plasmid, or cosmid DNA expression vectors; yeast transformed with yeast expression vectors; insect cell systems infected with baculovirus vectors; plant cell systems transformed with viral or bacterial expression vectors; or animal cell systems. For long-term production of recombinant proteins in mammalian systems, stable expression in cell lines may be effected. For example, nucleotide sequences able to encode any one of a light and heavy immunoglobulin chains described herein may be transformed into cell lines using expression vectors that may contain viral origins of replication and/or endogenous expression elements and a selectable or visible marker gene on the same or on a separate vector. The invention is not to be limited by the vector or host cell employed. In certain embodiments of the present invention, the nucleotide sequences able to encode any one of a light and heavy immunoglobulin chains described herein may each be ligated into a separate expression vector and each chain expressed separately. In another embodiment, both the light and heavy chains able to encode any one of a light and heavy immunoglobulin chains described herein may be ligated into a single expression vector and expressed simultaneously.
Alternatively, RNA and/or polypeptide may be expressed from a vector comprising nucleotide sequences able to encode any one of a light and heavy immunoglobulin chains described herein using an in vitro transcription system or a coupled in vitro transcription/translation system respectively.
In general, host cells that contain nucleotide sequences able to encode any one of a light and heavy immunoglobulin chains described herein and/or that express a polypeptide encoded by the nucleotide sequences able to encode any one of a light and heavy immunoglobulin chains described herein, or a portion thereof, may be identified by a variety of procedures known to those of skill in the art. These procedures include, but are not limited to, DNA/DNA or DNA/RNA hybridizations, PCR amplification, and protein bioassay or immunoassay techniques that include membrane, solution, or chip based technologies for the detection and/or quantification of nucleic acid or amino acid sequences. Immunological methods for detecting and measuring the expression of polypeptides using either specific polyclonal or monoclonal antibodies are known in the art. Examples of such techniques include enzyme-linked immunosorbent assays (ELISAs), radioimmunoassays (RIAs), and fluorescence activated cell sorting (FACS). Those of skill in the art may readily adapt these methodologies to the present invention.
Host cells comprising nucleotide sequences able to encode any one of a light and heavy immunoglobulin chains described herein may thus be cultured under conditions for the transcription of the corresponding RNA (mRNA, siRNA, shRNA etc.) and/or the expression of the polypeptide from cell culture. The polypeptide produced by a cell may be secreted or may be retained intracellularly depending on the sequence and/or the vector used. In an exemplary embodiment, expression vectors containing nucleotide sequences able to encode any one of a light and heavy immunoglobulin chains described herein may be designed to contain signal sequences that direct secretion of the polypeptide through a prokaryotic or eukaryotic cell membrane.
Due to the inherent degeneracy of the genetic code, other DNA sequences that encode the same, substantially the same or a functionally equivalent amino acid sequence may be produced and used, for example, to express a polypeptide encoded by nucleotide sequences able to encode any one of a light and heavy immunoglobulin chains described herein. The nucleotide sequences of the present invention may be engineered using methods generally known in the art in order to alter the nucleotide sequences for a variety of purposes including, but not limited to, modification of the cloning, processing, and/or expression of the gene product. DNA shuffling by random fragmentation and PCR reassembly of gene fragments and synthetic oligonucleotides may be used to engineer the nucleotide sequences. For example, oligonucleotide-mediated site-directed mutagenesis may be used to introduce mutations that create new restriction sites, alter glycosylation patterns, change codon preference, produce splice variants, and so forth.
In addition, a host cell strain may be chosen for its ability to modulate expression of the inserted sequences or to process the expressed polypeptide in the desired fashion. Such modifications of the polypeptide include, but are not limited to, acetylation, carboxylation, glycosylation, phosphorylation, lipidation, and acylation. In an exemplary embodiment, antibodies that contain particular glycosylation structures or patterns may be desired. Post-translational processing, which cleaves a “prepro” form of the polypeptide, may also be used to specify protein targeting, folding, and/or activity. Different host cells that have specific cellular machinery and characteristic mechanisms for post-translational activities (e.g., CHO, HeLa, MDCK, HEK293, and W138) are available commercially and from the American Type Culture Collection (ATCC) and may be chosen to ensure the correct modification and processing of the expressed polypeptide.
Since hybridoma cells are hybrid mouse cells, they are strictly used to produce murine antibodies. It is clear that the glycosyl side chains of such murine antibodies might significantly differ from the glycosylation pattern observed in human cells. Differences in phosphorylation pattern between human cells and hybridomas might also have an impact on the activity of the antibody. Furthermore, administration of murine antibodies to human usually induces an anti-antibody immune response that could potentially neutralize any of the biological activity that the murine antibody might have.
In order to minimize recognition of murine antibodies by the human immune system or for improving the biological activity of the antibodies in human, murine antibodies are advantageously converted into partially (e.g., chimeric) or fully humanized antibodies. Recombinant form of the light chain and heavy chain of the (partially or fully) humanized antibody may thus be introduced into a mammalian expression system other than hybridoma cells (such as 293 cells, CHO or else). Mammalian expression system may procure the advantage of having a resulting glycosylation pattern that is closer to that of naturally occurring human form of the antibodies.
For example, in the case of lytic IgG1 antibodies, the proper glycosylation of the immunoglobulin chains is necessary for effector functions. These biological functions of IgG1 monoclonal antibodies include antibody-dependent cell cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC), both of which will be greatly influenced by the type of glycosyl side chains that are grafted to the amino acids during expression in mammalian cells.
In addition, optimized mammalian cell expression systems will often secrete significantly a greater amounts of antibodies compared to hybridomas. Therefore, there is a practical and probably economical reason for adopting human cells for production.
Those of skill in the art will readily appreciate that natural, modified, or recombinant nucleic acid sequences may be ligated to a heterologous sequence resulting in translation of a fusion polypeptide containing heterologous polypeptide moieties in any of the aforementioned host systems. Such heterologous polypeptide moieties may facilitate purification of fusion polypeptides using commercially available affinity matrices. Such moieties include, but are not limited to, glutathione S-transferase (GST), maltose binding protein, thioredoxin, calmodulin binding peptide, 6-His (His), FLAG, c-myc, hemaglutinin (HA), and antibody epitopes such as monoclonal antibody epitopes.
In yet a further aspect, the present invention relates to a polynucleotide which may comprise a nucleotide sequence encoding a fusion protein. The fusion protein may comprise a fusion partner (e.g., HA, Fc, etc.) fused to the polypeptide (e.g., complete light chain, complete heavy chain, variable regions, CDRs etc.) described herein.
Those of skill in the art will also readily recognize that the nucleic acid and polypeptide sequences may be synthesized, in whole or in part, using chemical or enzymatic methods well known in the art. For example, peptide synthesis may be performed using various solid-phase techniques and machines such as the ABI 431A Peptide synthesizer (PE Biosystems) may be used to automate synthesis. If desired, the amino acid sequence may be altered during synthesis and/or combined with sequences from other proteins to produce a variant protein.
Antibody Conjugates
Although it is not always necessary, for detection or therapeutic purposes, the antibody or antigen binding fragment of the present invention may be conjugated with a detectable moiety (i.e., for detection or diagnostic purposes) or with a therapeutic moiety (for therapeutic purposes).
For detection purposes, an unconjugated antibody (primary antibody) may be used for binding to the antigen and a secondary antibody carrying a detectable moiety and capable of binding to the primary antibody may be added. However, as indicated above, the anti-SIGLEC 15 antibody may be conjugated with a detectable label and as such a secondary antibody may not be necessary,
A “detectable moiety” is a moiety detectable by spectroscopic, photochemical, biochemical, immunochemical, chemical and/or other physical means. A detectable moiety may be coupled either directly and/or indirectly (for example via a linkage, such as, without limitation, a DOTA or NHS linkage) to antibodies and antigen binding fragments thereof of the present invention using methods well known in the art. A wide variety of detectable moieties may be used, with the choice depending on the sensitivity required, ease of conjugation, stability requirements and available instrumentation. A suitable detectable moiety include, but is not limited to, a fluorescent label, a radioactive label (for example, without limitation, 125I, In111, Tc99, I131 and including positron emitting isotopes for PET scanner etc), a nuclear magnetic resonance active label, a luminiscent label, a chemiluminescent label, a chromophore label, an enzyme label (for example and without limitation horseradish peroxidase, alkaline phosphatase, etc.), quantum dots and/or a nanoparticle. Detectable moiety may cause and/or produce a detectable signal thereby allowing for a signal from the detectable moiety to be detected.
In another exemplary embodiment of the invention, the antibody or antigen binding fragment thereof may be coupled (modified) with a therapeutic moiety (e.g., drug, cytotoxic moiety).
In some instances, for therapeutic purposes, an unconjugated antibody may by itself be capable of sequestering the antigen, may block an important interaction between the antigen and another binding partner, may recruit effector cells, etc. However, as indicated above, the antibody may be conjugated with a therapeutic moiety.
In an exemplary embodiment, the antibodies and antigen binding fragments may comprise a chemotherapeutic or cytotoxic agent. For example, the antibody and antigen binding fragments may be conjugated to the chemotherapeutic or cytotoxic agent. Such chemotherapeutic or cytotoxic agents include, but are not limited to, Yttrium-90, Scandium-47, Rhenium-186, Iodine-131, Iodine-125, and many others recognized by those skilled in the art (e.g., lutetium (e.g., Lu177), bismuth (e.g., Bi213), copper (e.g., Cu67)). In other instances, the chemotherapeutic or cytotoxic agent may be comprised of, among others known to those skilled in the art, 5-fluorouracil, adriamycin, irinotecan, taxanes, pseudomonas endotoxin, ricin and other toxins.
Alternatively, in order to carry out the methods of the present invention and as known in the art, the antibody or antigen binding fragment of the present invention (conjugated or not) may be used in combination with a second molecule (e.g., a secondary antibody, etc.) which is able to specifically bind to the antibody or antigen binding fragment of the present invention and which may carry a desirable detectable, diagnostic or therapeutic moiety.

Such changes may be detected using, for example, electrophoresis followed by Western blot and coloration of the gel or blot, mass spectrometry, HPLC coupled with a computer or else. Apparatus capable of computing a shift in molecular weight are known in the art and include for example, PhosphorimagerTM.
When the antibody comprises for example a detectable label, the antigen-antibody complex may be detected by the fluorescence emitted by the label, radiation emission of the label, enzymatic activity of a label provided with its substrate or else.
Detection and/or measurement of binding between an antibody or antigen binding fragment and an antigen may be performed by various methods known in the art. Binding between an antibody or antigen binding fragment and an antigen may be monitored with an apparatus capable of detecting the signal emitted by the detectable label (radiation emission, fluorescence, color change etc.). Such apparatus provides data which indicates that binding as occurred and may also provide indication as to the amount of antibody bound to the antigen. The apparatus (usually coupled with a computer) may also be capable of calculating the difference between a background signal (e.g., signal obtained in the absence of antigen-antibody binding) or background noise and the signal obtained upon specific antibody-antigen binding. Such apparatuses may thus provide the user with indications and conclusions as to whether the antigen has been detected or not.
The sample may originate from a mammal (e.g., a human) which may have cancer or bone disease or may be suspected of having cancer or a bone disease or may experience bone loss or may be subject of experiencing bone loss.

EXAMPLES
Example 1
This example describes the pattern of expression of the Siglec-15 gene in osteoclasts and human tissue RNA samples
One of the most promising genes identified was termed AB-0326, which encodes the cell surface type I membrane protein, Siglec-15. This candidate was first isolated from a human osteoclast library and a similar RANKL-dependent upregulation was also confirmed in primary mouse osteoclasts as well as the mouse RAW 264.7 cells compared to precursor cells by RT-PCR (Sooknanan et al. 2007). The tissue expression profile of Siglec-15 was assessed to determine the specificity of expression, a criteria that was imposed on all targets that were chosen for validation. Peripheral blood mononuclear cells (PBMNCs) were obtained from 6 human donors and cultured in osteoclast differentiation medium (MCS-F and RANKL) for at least 14 days. Total RNA was isolated from precursors cells (no RANKL treatment (FIG. 1A, -) or at intermediate time intervals (FIG. 1A, ▴). One microgram of each RNA sample was converted to single-stranded cDNA using Thermoscript reverse transcriptase (Invitrogen, Burlington, ON) according to the manufacturer's instructions, diluted 200-fold, and used in a PCR reaction previously optimized to specifically amplify a fragment of the Siglec-15 transcript. The sequences of the oligonucleotides used in the PCR reaction are shown in SEQ ID NOS: 117 and 118. As shown in the Siglec-15 panel of FIG. 1A, the Siglec-15 transcript was either expressed at much lower level in the precursors cells compared to the differentiating osteoclasts. In addition, the level of Siglec-15 transcript increased as the differentiation progressed. By comparison, a known osteoclast marker gene, cathepsin K (CATK panel of FIG. 1A) was also upregulated during osteoclast differentiation. The oligonucleotides used to amplify the CATK message are displayed in SEQ ID NOS: 119 and 120. As a control, PCR reactions were conducted on the same samples with primers that specifically amplify the housekeeping gene glyceraldehyde-3-phosphate dehydrogenase (GAPDH panel of FIG. 1A). The sequences of the GAPDH-specific primers used in the PCR reaction are shown in SEQ ID NOS: 121 and 122. This latter reaction demonstrates that an equal amount of starting RNA was present in each sample. Total RNA from human normal tissues was purchased from a commercial vendor (Clontech, Mountain View, Calif.) As shown in FIG. 1B (Siglec-15 panel, Normal tissues), Siglec-15 was weakly detected in a single tissue (lung, lane 9) and completely absent from all other tissue samples. This underscores the strength of the Applicant's discovery approach in its ability to identify targets that are highly restricted to differentiating osteoclasts. The lane numbers in FIG. 1B correspond to the following tissues: The lanes correspond to the following tissues: lane 1, adrenal; 2, breast; 3, jejunum; 4, trachea; 5, liver; 6, placenta; 7, aorta; 8, brain; 9, lung; 10, adrenal cortex; 11, esophagus; 12, colon; 13, ovary; 14, kidney; 15, prostate; 16, thymus; 17, skeletal muscle; 18, vena cava; 19, stomach; 20, small intestine; 21, heart; 22, fallopian tube; 23, spleen; 24, bladder; 25, cervix; 26, pancreas; 27, ileum; 28, duodenum; 29, thyroid; 30, testicle; the blank lanes between lanes 10 and 11 and lanes 20 and 21 represent negative controls (no cDNA). Our results indicate that Siglec-15 is upregulated in differentiating osteoclasts, absent from virtually all normal human tissues and suggest that an antibody against Siglec-15 would interact significantly less with non-target tissues.
An additional expression profiling study was performed to determine the expression of Siglec-15 in cancer indications. One skilled in the art will recognize that the antibodies described in this invention might have utilities in cancer if it was found that the Siglec-15 gene was expressed in these types of indications. To address this, the PCR-based method was adapted to determine the expression pattern of the Siglec-15 transcript in cancer cell lines isolated from nine types of cancer. The cancer types represented by the cell lines are leukemia, central nervous system, breast, colon, lung, melanoma, ovarian, prostate, and renal cancer (see Table 4). These RNA samples were obtained from the Developmental Therapeutics Program at the NCI/NIH. Using the same RAMP RNA samples that was amplified from the total RNA samples obtained from the NCI, 500 ng of RNA was converted to single-stranded cDNA as described above. The cDNA reaction was diluted so that 1/200 of the reaction was used for each PCR experiment. PCR was conducted in 96-well plates using Hot-Start Taq Polymerase from Qiagen (Mississauga, ON) in a DNA Engine Tetrad from MJ Research. Half of the reaction mixture was loaded on a 1.2% agarose/ethidium bromide gel and the amplicons visualized with UV light. To verify that equal quantities of RNA was used in each reaction, the level of RNA was monitored with GAPDH expression.

As shown in FIG. 2, Siglec-15 was found to be expressed in several cancer types, in particular ovarian cancer, renal cancer, cancer of the central nervous system, and prostate cancer. In fact, Siglec-15 was detected in almost every cancer indication represented by these samples with the exception of leukemia. This result suggests that antibodies against Siglec-15 might have uses in cancer diseases.
The antibodies described in Example 2 (see below) may also be used for detection of Siglec-15 in cell lysates by immunoblotting. The entire open reading frame of human Siglec-15 cDNA was cloned into a mammalian expression vector downstream of a CMV promoter (pCDNA-Siglec-15). This construct, or a control empty vector which does not encode Siglec-15, were transfected into A375 melanoma cells, which express low endogenous levels of Siglec-15 protein. A pool of stable transfectants was isolated by selection with G418. Cell lysates from Siglec-15-transfected (+) and control (−) A375 cells were analysed by immunoblotting with monoclonal antibody E6. As shown in FIG. 13A, the antibody detects a single band of 35 kDa in the Siglec-15-transfected cells, but not in control cells. This closely matches the predicted molecular weight of Siglec-15 (35.62 kDa), based on the primary amino acid sequence (http://www.bioinformatics.org/sms/prot_mw.html). Lysates were also analyzed by immunoblotting with an anti-8-actin antibody to demonstrate that similar total amounts of lysates were loaded in each lane. This result demonstrates that, by immunoblotting, antibody E6 recognizes, in a highly specific manner, overexpressed Siglec-15 in lysates from cells transfected with cloned Siglec-15 cDNA.
To confirm that the increased Siglec-15 mRNA levels in differentiated human PBMNC (FIG. 1) correspond to an increase in Siglec-15 protein levels, lysates were prepared from human PBMNC treated with MCSF alone (non-differentiated, C) or MCSF and RANKL (differentiated, A) (FIG. 13B). Lysates were also prepared from RAW 264.7 cells left untreated (non-differentiated, C) or treated with RANKL (differentiated, A) (FIG. 13C). RAW 264.7 cells were shown previously to upregulate Siglec-15 mRNA levels upon induction of osteoclast differentiation by RANKL (Sooknanan, 2007). Analysis of these lysates by immunoblotting with antibody E9 demonstrates that, as predicted by RT-PCR studies, there is a dramatic increase in Siglec-15 protein levels both in PBMNC and RAW 264.7 cells upon differentiation into osteoclasts (FIGS. 13B and 13C).
RT-PCR analysis of mRNA from the NCI60 panel (FIG. 2) indicated that a particularly high proportion of CNS-derived cancer cell lines express Siglec-15, while a recent microarray study found a small set of cancer cell lines, including the U87 glioblastoma line that is not part of the NCI60 panel, that express very high levels of Siglec-15 mRNA (Shankavaram, 2007). Therefore, we tested whether endogenous expression of Siglec-15 protein could be detected in U87 cells. Indeed, a protein the size of Siglec-15 is detected by immunoblotting of U87 cell lysates. To confirm the identity of this protein, U87 cells were transfected with a pool of small interfering RNAs (siRNAs) targeting Siglec-15 (SIGLECI5 siGENOME SMARTpool, Dharmacon) (+) or with a control, non-targeting siRNA pool (-, FIG. 13D) and allowed to grow for 72 h before cell lysis. Consistent with its identification as Siglec-15, treatment with the targeted siRNA resulted in reduced expression of this protein compared to the non-targeted control (FIG. 13D). To examine whether Siglec-15 is found at the cell surface in cancer cells, we analyzed the siRNA-treated U87 cells by flow cytometry. Living cells were placed on ice and stained with Siglec-15 antibody E9 (see Example 2) or an isotype control antibody, under conditions which allow antibody binding to extracellular but not intracellular antigens. Treatment with the targeted siRNA resulted in reduced binding of antibody E9 but had no effect on binding of the control antibody (FIG. 13E). Together, these results demonstrate that Siglec-15 may be expressed in cancer cells, and that it is accessible for antibody binding at the cell surface.
Example 2
This example provides details pertaining to the family of monoclonal antibodies that bind to Siglec-15.
To generate monoclonal antibodies, recombinant human Siglec-15 was produced in 293E cells using the large-scale transient transfection technology (Durocher et al., 2002; Durocher, 2004). A cDNA encoding amino acids 20-259 of SEQ ID NO:2 (see SEQ ID NO:123) was amplified by PCR using a forward primer that incorporated a BamHI restriction site (SEQ ID NO:124) and a reverse primer that incorporated a NotI restriction site (SEQ ID NO:125). The resulting PCR product was digested with BamHI and NotI and the fragment was ligated into the expression vector pYD5 (SEQ ID NO:126) that was similarly digested with the same restriction enzymes to create a vector called pYD5-0326. The pYD5 expression plasmid contains the coding sequence for the human Fc domain that allows fusion proteins to be generated as well as the sequence encoding the IgG1 signal peptide to allow the secretion of the fusion protein into the culture medium. For each milliliter of cells, one microgram of the expression vector, called pYD5-032620-259, was transfected in 2936E cells grown in suspension to a density of 1.5-2.0 million cells/ml. The transfection reagent used was polyethylenimine (PEI), (linear, MW 25,000, Cat#23966 Polysciences, Inc., Warrington, Pa.) which was included at a DNA:PEI ratio of 1:3. Growth of the cells was continued for 5 days after which the culture medium was harvested for purification of the recombinant Fc-032620-259 fusion protein. The protein was purified using Protein-A agarose as instructed by the manufacturer (Sigma-Aldrich Canada Ltd., Oakville, ON). A representative polyacrylamide gel showing a sample of the purified Fc-032620-259 (indicated as Fc-Siglec-1520-259) is shown in FIG. 3.
The antibodies that bind Siglec-15 were generated using the Biosite phage display technology. A detailed description of the technology and the methods for generating these antibodies can be found in the U.S. Pat. No. 6,057,098. Briefly, the technology utilizes stringent panning of phage libraries that display the antigen binding fragments (Fabs). After a several rounds of panning, a library, termed the Omniclonal, was obtained that was enriched for recombinant Fabs containing light and heavy chain variable regions that bound to Siglec-15 with very high affinity and specificity. From this library, more precisely designated Omniclonal AL0025Z1, 96 individual recombinant monoclonal Fabs were prepared from E. coli and tested for Siglec-15 binding.
To measure the relative binding of each individual monoclonal antibody, recombinant human Fc-Siglec-1520-259 was produced in 293E cells using the large-scale transient transfection technology (Durocher et al., 2002; Durocher, 2004). The 96-well master plate of monoclonal preparations contained different concentrations of purified anti-Siglec-15 Fabs in each well. A second stock master plate was prepared by diluting the Fabs to a final concentration of 10 μg/ml from which all subsequent dilutions were performed for ELISA measurements. To carry out the binding of Fc-Siglec-15 to the monoclonal preparations, the Fc-Siglec-1520-259 was biotinylated with NHS-biotin (Pierce, Rockford, Ill.) and 10 ng/well was coated in a streptavidin 96-well plate. One nanogram of each Fab monoclonal preparation was added to each well and incubated at room temperature for 30 minutes. Bound antibody was detected with HRP-conjugated mouse anti-kappa light chain antibody in the presence of TMB liquid substrate (Sigma-Aldrich Canada Ltd., Oakville, ON) and readings were conducted at 450 nm in microtiter plate reader. As shown in FIG. 4A, a total of 53 (highlighted dark grey) monoclonal antibodies displayed significant binding in this assay (>0.2 arbitrary OD450 units). The antibodies were purposely diluted to 1 ng/well to accentuate the binding of those antibodies with the most affinity for Siglec-15. Since the antibodies were generated using a Fc fusion protein, the monoclonals were also tested in an ELISA using biotinylated Fc domain only. As shown in FIG. 4B, 17 antibodies interacted with the Fc moiety of the Fc-Siglec-1520-259 (highlighted light grey). The values presented in bold (see FIG. 4) represent the exemplary antibodies 25A1, 25B4, 25B8, 25C1, 25D8, 25E5, 25E6, and 25E9. These data also revealed that the binding of the antibodies varied from well to well indicating that they exhibited different affinities for Siglec-15.
The applicant noted that the antibody or antigen binding fragment of the present invention may bind efficiently to the antigen, in fact it was found that 1 ng of antibody is capable of binding to less than 500 ng of SEQ ID NO.:2.
The specificity of these antibodies for Siglec-15 was assessed by testing their binding to two other members of the Siglec family, CD33 and Siglec-2. CD33 (GeneBankTM accession No. NM_001772.3) is the prototype of the CD33-related family of Siglecs: among human proteins, these Siglecs share the highest amino acid sequence similarity with Siglec-15 (around 29% sequence identity between their two respective N-terminal Ig-like domains). Siglec-2 (GeneBankTM accession No. NM_001771.3) is less similar (23% sequence identity), but like Siglec-15 and unlike most other Siglecs, it has a marked preference for binding α2-6-linked sialic acid conjugates (Angata 2007, Blixt 2003). Sequences comprising the V-set and N-terminal C2-set Ig-like domains of Siglec-2 and CD33 (corresponding to the region of Siglec-15 used as the antigen for antibody production) were cloned from a human PBMNC cDNA library into the pYD5 vector. Supernatants from 293-6E cells transfected with these constructs, as wells as from non-transfected 293-6E cells or those transfected with pYD5-Siglec-15 or pYD5 empty vector, were analyzed by immunoblotting with an anti-Fc antibody to evaluate expression levels (FIG. 14A). Transfection of these constructs resulted in expression of Fc-tagged proteins of the expected size (FIG. 14A). Aliquots of these supernatants were adsorbed onto PVDF by vacuum dot blotting (Bio-dot apparatus, Bio-Rad), and binding of representative Siglec-15 monoclonal antibodies was evaluated (Western blots were not used because many antibodies react only with the native, non-denatured form of Siglec-15). As controls, anti-Fc and anti-Siglec-15 omniclonal antibodies reacted with all four Fc-tagged proteins (FIG. 14B). In contrast, monoclonal antibodies D8 and E9 show no detectable binding to Fc alone, Siglec-2 or CD33, indicating that they are highly specific for Siglec-15.
Example 3
This example discloses the methods used to convert the Fabs into full IgG2 chimeric monoclonal antibodies. A scheme of the methodology is presented in FIG. 5.
In order to conduct in vitro and in vivo studies to validate the biological function of the antigen the light and heavy chain variable regions contained in the Fabs was transferred to full antibody scaffolds, to generate mouse-human chimeric IgG2s. The expression vectors for both the light and heavy immunoglobulin chains were constructed such that i) the original bacterial signal peptide sequences upstream of the Fab expression vectors were replaced by mammalian signal peptides and ii) the light and heavy chain constant regions in the mouse antibodies were replaced with human constant regions. The methods to accomplish this transfer utilized standard molecular biology techniques that are familiar to those skilled in the art. A brief overview of the methodology is described here (see FIG. 5).
Light Chain Expression Vector—
an existing mammalian expression plasmid, called pTTVH8G (Durocher et al., 2002), designed to be used in a 293E transient transfection system was modified to accommodate the mouse light chain variable region. The resulting mouse-human chimeric light chain contained a mouse variable region followed by the human kappa constant domain. The cDNA sequence encoding the human kappa constant domain was amplified by PCR with primers OGS1773 and OGS1774 (SEQ ID NOS:127 and 128, respectively). The nucleotide sequence and the corresponding amino acid sequence for the human kappa constant region are shown in SEQ ID NOS:129 and 130, respectively. The resulting 321 base pair PCR product was ligated into pTTVH8G immediately downstream of the signal peptide sequence of human VEGF A (NM_003376). This cloning step also positioned unique restriction endonuclease sites that permitted the precise positioning of the cDNAs encoding the mouse light chain variable regions. The sequence of the final expression plasmid, called pTTVK1, is shown in SEQ ID NO:131. Based on the sequences disclosed in Table 2, PCR primers specific for the light chain variable regions of antibodies 25A1, 25B4, 25B8, 25C1, 25D8, 25E5, 25E6, and 25E9 (SEQ ID NOS:37, 41, 45, 49, 53, 57, 61, and 65, respectively) were designed that incorporated, at their 5′-end, a sequence identical to the last 20 base pairs of the VEGF A signal peptide. The sequences of these primers are shown in SEQ ID NO:132 for 25A1; SEQ ID NO:133 for 25B4, 25B8, 25C1, 25D8, and 25E9; SEQ ID NO:134 for 25E5, and SEQ ID NO:135 for 25E6, respectively. The same reverse primer was used to amplify all four light chain variable regions since the extreme 3′-ends were identical. This primer (SEQ ID NO:136) incorporated, at its 3′-end, a sequence identical to the first 20 base pairs of the human kappa constant domain. Both the PCR fragments and the digested pTTVK1 were treated with the 3′-5′ exonuclease activity of T4 DNA polymerase resulting in complimentary ends that were joined by annealing. The annealing reactions were transformed into competent E. coli and the expression plasmids were verified by sequencing to ensure that the mouse light chain variable regions were properly inserted into the pTTVK1 expression vector. Those skilled in the art will readily recognize that the method used for construction of the light chain expression plasmids applies to all anti-Siglec-15 antibodies contained in the original Fab library.
Heavy Chain Expression Vector—
the expression vector that produced the heavy chain immunoglobulins was designed in a similar manner to the pTTVK1 described above for production of the light chain immunoglobulins. In the case of the chimeric anti-Siglec-15 antibodies, IgG2 isotype was required which is the preferred type for stable, blocking antibodies. To this end, the constant regions (CH1, CH2, and CH3) of the human IgG2 immunoglobulin were amplified and ligated into a pre-existing IgG1 expression vector and the detailed methods are described herein. Plasmid pYD11 (Durocher et al., 2002), which contains the human IgGK signal peptide sequence as well as the CH2 and CH3 regions of the human Fc domain of IgG1, was modified by ligating the cDNA sequence encoding the human constant CH1 region. PCR primers OGS1769 and OGS1770 (SEQ ID NOS:137 and 138), designed to contain unique restriction endonuclease sites, were used to amplify the human IgG1 CH1 region containing the nucleotide sequence and corresponding amino acid sequence shown in SEQ ID NOS:139 and 140. Following ligation of the 309 base pair fragment of human CH1 immediately downstream of the IgGK signal peptide sequence, the resulting plasmid was digested with the restriction enzymes ApaI and NsiI. These enzymes that digest both the constant IgG1 and IgG2 cDNAs in exactly the same positions that permits the IgG1 constant sequence to be replaced by the human IgG2 sequence in the expression vector. The cDNA encoding the human IgG2 constant domains was obtained from a commercially available source (Open Biosystems, Huntsville, Ala.). The final plasmid used to express the IgG2 immunoglobulin heavy chain was designated pYD19 and the sequence is shown in SEQ ID NO:141. When a selected heavy chain variable region is ligated into this vector, the resulting plasmid encodes a full IgG2 heavy chain immunoglobulin with human constant regions. Based on the sequences disclosed in Table 2, PCR primers specific for the heavy chain variable regions of antibodies 25A1, 25B4, 25B8, 25C1, 25D8, 25E5, 25E6, and 25E9 (SEQ ID NOS:39, 43, 47, 51, 55, 59, 63, and 67, respectively) were designed that incorporated, at their 5′-end, a sequence identical to the last 20 base pairs of the IgGK signal peptide. The sequences of these primers are shown in SEQ ID NOS:142 for 25A1; SEQ ID NO:143 for 24B4 and 25D8; SEQ ID NO:144 for 25B8, 25C1, and 25E9; SEQ ID NO:145 for 25E5; and SEQ ID NO:146 for 25E6, respectively. The same reverse primer was used to amplify all four heavy chain variable regions since the extreme 3′-ends were identical. This primer (SEQ ID NO:147) incorporated, at its 3′-end, a sequence identical to the first 20 base pairs of the human CH1 constant domain. Both the PCR fragments and the digested pYD19 were treated with the 3′-5′ exonuclease activity of T4 DNA polymerase resulting in complimentary ends that were joined by annealing. The annealing reactions were transformed into competent E. coli and the expression plasmids were verified by sequencing to ensure that the mouse heavy chain variable regions were properly inserted into the pYD19 expression vector. Those skilled in the art will readily recognize that the method used for construction of the heavy chain expression plasmids applies to all anti-Siglec-15 antibodies contained in the original Fab library.
Expression of Human IgG2s in 293E Cells—
The expression vectors prepared above that encoded the light and heavy chain immunoglobulins were expressed in 293E cells using the transient transfection system (Durocher et al., 2002). By virtue of the signal peptides incorporated at the amino-termini of both immunoglobulin chains, the mature IgG2 was harvested from the serum-free culture medium of the cells. The methods used for co-transfecting the light and heavy chain expression vectors were described herein. For each milliliter of cells, one microgram of a combination of both the light and heavy chain expression plasmids was transfected in 293E cells grown in suspension to a density of 1.5-2.0 million cells/ml. The ratio of light to heavy chain plasmid was optimized in order to achieve the most yield of antibody in the tissue culture medium and it was found to be 9:1 (L:H). The transfection reagent used was polyethylenimine (PEI), (linear, MW 25,000, Cat#23966 Polysciences, Inc., Warrington, Pa.) which was included at a DNA:PEI ratio of 1:3. Growth of the cells was continued for 5 days after which the culture medium was harvested for purification of the IgG2 chimeric monoclonal antibodies. The protein was purified using Protein-A agarose as instructed by the manufacturer (Sigma-Aldrich Canada Ltd., Oakville, ON).
To determine the relative binding affinity of selected monoclonals more accurately, increasing concentration of the Fabs was incubated with biotinylated Fc-Siglec-1520-259. Ten nanograms of biotinylated Fc-Siglec-1520-259 was coated in streptavidin microtiter plates and increasing amounts of either Fabs (FIG. 6A) or the chimeric IgG2 monoclonals 25B4, 25B8, 25C1, 25D8, 25E6, and 25E9 (FIG. 6B) were added as indicated. As depicted in FIG. 6A and FIG. 6B, the binding of the 25B4, 25B8, 25C1, 25D8, 25E6, and 25E9 chimeric IgG2 monoclonal antibodies was very similar to the Fabs. This result shows that the transposition of the variable domains from the mouse Fabs into a human IgG2 backbone did not significantly affect the capacity of the light and heavy chain variable regions to confer Siglec-15 binding.
Example 4
This example describes the use of anti-Siglec-15 antibodies for inhibiting the differentiation of osteoclasts.
Human PBMNCs (AllCells, Emoryville, Calif.) were placed in the appropriate culture medium for 24 h at 37 C in a 5% CO2 atmosphere. The cells were seeded in 96-well plates at a cell density of 100,000 cells/ml and treated with increasing concentration (0.01 μg/ml-100 μg/ml) of anti-Siglec-15 IgG2 chimeric monoclonal antibodies in the presence of 35 ng/ml M-CSF and 30 ng/ml RANKL. Undifferentiated precursor cells were treated only with M-CSF, The control wells were treated with a non-Siglec-15 binding IgG2 (FIG. 7D). The cells were fixed, stained for TRAP, and multinucleated cells counted and photographed (magnification 40×). As depicted in FIG. 7A to FIG. 7D, mAbs targeting Siglec-15 could efficiently inhibit the differentiation of human osteoclasts in a dose-dependent manner. Inhibition of osteoclast differentiation was observed to varying extents with every exemplary Siglec-15 antibody that was tested but the most active monoclonals were 25B8 (FIG. 7A), 25E6 (FIG. 7B), and 25E9 (FIG. 7C). Cells treated with a control chimeric IgG2 were not inhibited (FIG. 7D). This result is in complete agreement with the experiments disclosed by Sooknanan (Sooknanan et al., 2007) that showed that knockdown of Siglec-15 expression by RNA interference caused inhibition of human osteoclast differentiation.
The biological function of differentiated osteoclasts is to resorb bone and thus the activity of osteoclasts should also be inhibited by antibodies that target Siglec-15. To test this, human PBMNCs were seeded on synthetic calcium phosphate substrate discs (BD BioCoatTM OsteologicTM MultiTest Slides) and cultured in similar conditions as described above. The precursor cells were treated with M-CSF (FIG. 12A) or M-CSF and RANKL (FIG. 12B) in the presence of either a control isotype IgG (FIG. 12E and FIG. 12F) or the 25D8 (FIG. 12C and FIG. 12D) or 25E9 (FIG. 12G and FIG. 12H) anti-Siglec-15 antibodies. The antibodies were at a concentration of 1 μg/ml or 10 μg/ml. Once fully matured osteoclasts were present in the control untreated wells. The cells were scarped off the discs and the remaining bone substrate was stained using a standard von Kossa stain which renders the calcium mineral brown. As shown in FIG. 12A to FIG. 12H, the wells containing undifferentiated osteoclasts (FIG. 12A) showed no evidence of degradation of the substrate which appears as white spots on the surface (degradation pits). As expected, the cells treated with RANKL had evidence of significant degradation and the surface contained many pits (FIG. 12B). Similarly, the osteoclasts treated with the control IgG could also degrade the bone substrate which demonstrated that these control antibodies did not inhibit osteoclast activity non-specifically (FIG. 12E and FIG. 12F). When the differentiating osteoclasts were treated with the anti-Siglec-15 antibodies, the 25E9 candidate efficiently inhibited bone degradation in this assay (FIG. 12G and FIG. 12H). By contrast, the 25D8 antibody did not inhibit degradation in this assays (FIG. 12C and FIG. 12D). Taken together, these results (FIG. 7A to FIG. 7D and FIG. 12A to FIG. 12H) demonstrate that antibodies against Siglec-15 inhibit osteoclast differentiation and bone degradation activity.
In a parallel experiment, mouse PBMNCs were treated in a similar manner. As depicted in FIG. 8A to FIG. 8D, anti-Siglec-15 chimeric antibodies could inhibit the differentiation of mouse osteoclasts as exemplified by the chimeric mAbs designated 25B8 (FIG. 8A), 25E6 (FIG. 8B), and 25D8 (FIG. 8C) in comparison with a control IgG2. This result confirms that the monoclonal antibodies that were generated against the human orthologue of Siglec-15 are cross-reactive against the mouse Siglec-15 protein as well. This was experimentally verified using an ELISA. A fragment of the mouse Siglec-15 cDNA was amplified corresponding to amino acids 21-256 using oligonucleotides containing the sequences shown in SEQ ID NOS: 159 and 160. This PCR fragment was ligated into the pYD5 expression vector as was described for the human Siglec-15 fragment for expression in 293-6E cells. The recombinant Fc-mouse Siglec-15 was purified using Protein-A affinity chromatography.
An exemplary anti-Siglec-15 monoclonal Fab designated 25C8 was incubated with either Fc-human(h)Siglec-1520-259 or Fc-mouse(m)Siglec-1521-256. The results (see FIG. 9) indicate that the binding activity of the antibodies that were generated against the human Siglec-15 also cross-react with the mouse orthologue of Siglec-15.
The results described above clearly demonstrate the importance of Siglec-15 in osteoclastogenesis. Attenuation of Siglec-15 expression in osteoclast precursor cells results in cells that are highly impaired in their ability to form multinucleated mature osteoclasts. Thus, targeting Siglec-15 with an inhibitor, in particular a therapeutic monoclonal antibody, would prove to be a very selective way to target those cells that are directly responsible for bone degradation during acute metastatic bone cancer or chronic osteoporosis.
Example 5
This example pertains to the ability of anti-Siglec-15 antibodies to block binding of Siglec-15 to sialic acid (SA) conjugates.
The formation of sialylated glycoproteins is required for proper osteoclastogenesis (Takahata et al., 2007). Siglec-15 binds sialic acid, and this binding is dependent on the amino acid residue R143 (Angata 2007). One mechanism by which Siglec-15 antibodies inhibit osteoclast formation could involve interference with their target's sialic acid-binding function due to interactions with an epitope encompassing R143. To examine this possibility, we performed an ELISA-based assay to test the ability of Siglec-15 antibodies to block binding of recombinant Fc-Siglec-15 to Neu5Aca2-6-GalNAc-PAA-Biotin (Glycotech, Rockville, Md.), which is a preferred, sialic acid-containing binding partner of Siglec-15 (Angata 2007). Fc-Siglec-15 was immobilized on a Protein A-coated microtiter plate, and different Siglec-15 antibodies were then applied. After incubation and removal of unbound antibody, Neu5Aca2-6-GalNAc-PAA-Biotin was added. This biotinylated probe should form a complex with Siglec-15 only if an antibody is not blocking the sialic acid binding site. The presence of the biotinylated probe was detected using streptavidin-HRP by standard methods. As shown in FIG. 15, anti-Siglec-15 omniclonal and 25D8 antibodies inhibit sialic acid binding compared to a non-targeting, control antibody. Antibody E6 also has a clear, but less pronounced effect. Antibody E9 has little effect, indicating that its epitope does not overlap with the sialic acid binding site. Addition of a control antibody (FIG. 15, see ctl IgG2) did not prevent the binding of sialic acid moiety to Siglec-15. The method was highly dependent on the presence of Siglec-15 since no binding was detected when only the Fc was coated in the plates nor was there any binding when the SA was omitted (FIG. 15, see no SA, Fc+SA, and Fc only). Together, these results demonstrate that the Siglec-15 monoclonal antibodies can interfere, to varying extents, with the sialic acid binding function of Siglec-15 likely due to interactions near R143. This property could be important for their effects on osteoclastogenesis.
