Description

[0001] This application is a divisional application of Chinese patent application No. 201580023098.5, filed on March 3, 2015, entitled "Antibody, Use and Method". Technical Field

[0002] This invention relates to anti-human OX40L antibodies, novel medical uses, and methods. Background Technology

[0003] OX40 ligand (OX40L) is a member of the TNF family, a 34 kDa type II transmembrane protein. The crystalline complex of human OX40 and OX40L is a trimer consisting of one OX40L (trimer) and three OX40 monomers. The human extracellular domain is 42% homologous to mouse OX40L.

[0004] OX40L is not constitutively expressed, but it can be induced in professional APCs such as B cells, dendritic cells (DCs), and macrophages. It can also induce expression of OX40L in other cell types such as Langerhans cells, endothelial cells, smooth muscle cells, mast cells, and natural killer (NK) cells. T cells can also express OX40L. The OX40L receptor, OX40, is expressed on activated T cells (CD4 and CD8 T cells, Th2, Th1, and Th17 cells) and CD4+ T cells. + FoxP3 + It is expressed on cells, even when it is not activated.

[0005] The interaction between OX40 and OX40L occurs during T cell-DC interaction 2 or 3 days after antigen recognition. After leaving the DC, OX40-expressing T cells can interact with OX40L-expressing cells, but not the DCs, and receive OX40 signals from these cells. This provides essential signaling for the generation of memory T cells, enhanced Th2 responses, and prolonged inflammatory responses. OX40 signaling entering responding T cells causes them to resist Treg-mediated inhibition.

[0006] Graft-versus-host disease (GVHD) is a leading cause of death following allogeneic bone marrow transplantation. In the acute form of this disease, mature T cells present in the bone marrow graft recognize donor tissue as foreign in a damaged tissue environment. This recognition triggers donor T cell activation and proliferation via host APCs, followed by T cell migration to the liver, spleen, intestine, skin, and lungs, causing tissue damage through CTL effector responses and the release of inflammatory cytokines / chemokines. Acute onset typically occurs within the first 100 days post-transplantation (Hill-Ferrara, Blood, May 1, 2000, Vol. 95, No. 9, pp. 2754-275; Reddy-Ferrara, Blood, Vol. 17, No. 4, December 2003).

[0007] Chronic GvHD typically occurs 100 days after transplantation and is thought to involve several factors, including thymic damage caused by previous acute GvHD leading to reduced clearance of pathogenic T cells (Zhang et al., September 1, 2007, Vol. 179, No. 5, pp. 3305-3314), fibrotic TGF-β upregulation (McCormick et al., J Immuno, November 15, 1999, Vol. 163, No. 10, pp. 5693-5699), and B-cell components driven by elevated B-cell activating factor (BAFF) (Sarantopoulos et al., Clin Cancer Res, October 15, 2007, pp. 13; 6107), as well as autoantibodies against platelet-derived growth factor receptor (Svegliati et al., Blood, July 1, 2007, Vol. 110, No. 1, pp. 237-241).

[0008] Clinical studies have confirmed that OX40 is upregulated in both acute (Morante et al., Clinical and Experimental Immunology, 145:36-43) and chronic (Kotani et al., Blood, November 15, 2001, Vol. 98, No. 10, 3162-3164) GvHD. Administration of antagonistic anti-OX40L improved survival in a lethal acute mouse model of GvHD, with a 70% survival rate in the treated group compared to the untreated group, all of whom died by day 43 (Tsukada et al., Blood, April 1, 2000, Vol. 95, No. 7), while treatment with agonistic anti-OX40 Ab accelerated the disease and mortality (Blazar et al., Blood, May 1, 2003, Vol. 101, No. 9, 3741-3748). Blocking the OX40-OX40L interaction has been shown to be effective in several other inflammatory diseases, including the use of anti-OX40L Ab in treating a mouse model of colitis (Totsuka et al., AJP-GI, April 1, 2003, Vol. 284, No. 4, pp. 595-603), and anti-OX40LAb can block the development of diabetes in NOD mice (Pakala et al., European Journal of Immunology, Vol. 34, No. 11, pp. 3039-3046, November 2004).

Detailed Implementation Plan

[0046] The present invention provides the following aspects 1-113.

[0047] This invention is useful, for example, for the treatment or prevention of transplant rejection, such as graft-versus-host disease (GvHD) or allogeneic transplant rejection. This invention is also useful, for example, for the treatment or prevention of inflammatory bowel disease, such as UC or CD, or for the treatment or prevention of inflammatory airway diseases or symptoms.

This invention is also useful, for example, for the treatment or prevention of Schnitzler syndrome. This invention is also useful, for example, for the treatment or prevention of non-infectious scleritis.

[0048] 1. An antibody or fragment thereof that specifically binds to hOX40L, used in a method for treating or preventing hOX40L-mediated diseases or conditions in a human, wherein the antibody or fragment is administered to the human, wherein the antibody or fragment is used to treat or prevent the hOX40L-mediated diseases or conditions by reducing one, several, or all of the following:

[0049] a. Secretion of human cytokines selected from TNFα, IL-2, IL-3, IL-4, IL-5, IL-6, IL-8, IL-9, IL-10, IL-13, IL-17, RANTES, and interferon-γ;

[0050] b. The proliferation of human white blood cells; and

[0051] c. Binding of the hOX40 receptor expressed by human T cells to the hOX40L expressed by endothelial cells.

[0052] The inventors have thus identified for the first time the reduction of (a), (b) and (c) as a pathway for the treatment and / or prevention of OX40L-mediated diseases and symptoms in humans, and they have provided antibodies and antibody fragments for this purpose.

[0053] In one instance, the secretion is leukocyte secretion. In one instance, (a) is indicated by significantly elevated cytokine levels in human blood, plasma, or serum.

[0054] In one instance, the cytokines are selected from (i) TNFα, (ii) IL-2, and (iii) interferon γ. In one instance, the cytokine is TNFα. In one instance, the cytokine is IL-2. In one instance, the cytokine is interferon γ. In one instance, the cytokines are (i) and (ii); or (i) and (iii); or (ii) and (iii); or (i)-(iii).

[0055] In one instance, the reduction in (a), (b), or (c), or any other reduction disclosed herein, is a reduction of at least 10 or 20% compared to the level in a person at risk of or suffering from an hOX40L-mediated disease or condition. In one instance, the latter is a person prior to administration of the antibody or fragment as described in aspect 1; in another instance, the latter is a different person. In one instance, the reduction is at least 10, 20, 30, 40, 50, or 60%.

[0056] (i) In one instance, the antibody or fragment described in an in vitro assay (as further explained below) is capable of reducing the secretion of related cytokines from leukocytes (e.g., human T cells), and therefore administration of such an antibody or fragment to a human results in a reduction of (a).

[0057] (ii) In one instance, the antibody or fragment described herein is capable of reducing the proliferation of leukocytes (e.g., human PBMCs and / or human T cells) in an in vitro assay (as further explained below), and therefore administration of such an antibody or fragment to a human results in the reduction of (b).

[0058] (iii) In one instance, the antibody or fragment described herein was able to reduce the binding of hOX40 expressed on human T cells to hOX40L expressed on endothelial cells in an in vitro assay (as further explained below), and therefore administration of such an antibody or fragment to a human resulted in a reduction of (c).

[0059] In one instance, (i) and (ii); or (i) and (iii); or (ii) and (iii); or (i)-(iii) apply.

[0060] Alternatively or additionally, the reduction can be assessed using samples from the treated person. For example, see J Clin Immunol. 2004 Jan; 24(1): 74-85; “Increased expression of CCL20 in human inflammatory bowel disease”; Kaser A et al. This publication provides examples of generally applicable techniques for using tissue biopsy and reading out reduced cytokine levels indicating decreased cytokine secretion in vivo following antibody treatment. Similar methods can be used to determine a reduction in the secretion of one or more cytokines in a person who has received the antibody of the present invention. Those skilled in the art will be familiar with techniques for assessing cytokine levels in a patient or patient sample, such as by using one or more of the following: tissue biopsy, immunohistochemistry, immunofluorescence, tissue staining, cytokine mRNA quantification (e.g., using PCR, such as Taqman). TM PCR), cytokine protein detection and quantification (e.g., using cytokine-specific antibody tools and quantification, such as by ELISA or another standard protein quantification technique). For example, when the disease or symptom is a gastrointestinal disease or symptom (e.g., IBD), a biopsy of relevant intestinal tissue from a patient who has received the antibody of the present invention can be performed, followed by quantification of cytokine mRNA and / or cytokine proteins (e.g., using quantitative PCR). The results are compared with cytokine quantification in relevant biopsy tissue from the same patient prior to antibody administration or with another patient with the same disease or symptom but not receiving anti-OX40L treatment or treatment for the disease or symptom. In this way, those skilled in the art can determine that the antibody of the present invention reduces cytokine secretion in human recipients. Instead of assessing intestinal tissue levels, depending on the characteristics and location of the disease or symptom, different tissues or samples from human patients can be used. For example, when the disease or symptom is an airway (e.g., lung) disease or symptom, lung or other tissue samples may be taken for cytokine assessment. Optionally, as will be apparent to those skilled in the art, bronchoalveolar lavage (BAL) samples can be used. In another instance, for some diseases or conditions, the reduction in cytokines in the blood, serum, or plasma of a person who has received the antibody of the present invention can be assessed, and then compared with levels prior to receiving the antibody or with levels in untreated individuals, as discussed above.

[0061] As is known in the art, the term “leukocyte” includes, for example, one or more of lymphocytes, polymorphonuclear leukocytes, and monocytes. As will also be apparent to those skilled in the art, the term “monocyte” includes, for example, peripheral blood mononuclear cells (PBMCs) or cells of monocyte origin, such as dendritic cells (DCs). See, for example, Immunobiology, November 2013; 218(11): 1392-401. doi: 10.1016 / j.imbio.2013.07.005. Epub July 25, 2013; “Leukoreduction system chambers are an efficient, valid, and economic source of functional monocyte-derived dendritic cells and lymphocytes”, Pfeiffer IA et al.

[0062] As will be apparent to those skilled in the art, tissue biopsy, staining, and histological techniques can be used to assess the proliferation of leukocytes, such as lamina propria lymphocytes (LPL). Hematoxylin and eosin stains (H&E stains or HE stains), for example, are commonly used histologically to look for infiltrating lymphocytes (in various human tissues) and are among the primary histological stains. They are the most widely used stains in medical diagnostics and are often the gold standard, and can also be used to assess leukocyte proliferation according to the present invention. For example, gastrointestinal tissue (e.g., intestinal tissue) from a person with or at risk of hOX40L-mediated disease or condition can be obtained, stained, and the extent of LPL infiltration can be assessed. Comparisons can be made between such tissues from persons who have received the antibodies of the present invention, compared to the extent of infiltration in tissues obtained from the same person prior to administration or from tissues from another person who has not yet received treatment but is at risk of or has the disease or condition. For example, comparisons can be made between intestinal tissues taken from the same (or different) persons with IBD.

[0063] Standard binding assays familiar to the technician can be used, such as ELISA or SPR, to determine whether the antibody or fragment can reduce the binding of the hOX40 receptor expressed on human T cells to the hOX40L expressed on endothelial cells.

[0064] Inflammatory bowel disease (IBD) is a chronic inflammatory condition affecting the gastrointestinal tract, with a significantly increasing incidence and a tendency towards more severe clinical phenotypes. The disease is characterized by an amplified immune response to the luminal flora, suggesting a possible involvement of a deficiency in the gut microbiota barrier function, and research supports this insight (Cucchiara et al., 2012; Josens et al., 2012; Manichanh et al., 2012; Salzman et al., 2007, all cited in Deuring et al., “The cellbiology of the intestinal epithelium and its relation to inflammatory bowel disease,” The International Journal of Biochemistry & Cell Biology 45 (2013) 798-806). IBD comprises two main subtypes: Crohn's disease (CD) and ulcerative colitis (UC). CD patients may have inflammatory lesions throughout their gastrointestinal tract, while inflammation in UC patients is confined to the colon. Also see Hisamatsu et al. (“Immune aspects of the pathogenesis of inflammatory bowel disease”, Pharmacology & Therapeutics 137 (2013) 283-297) and the documents cited therein.

[0065] Granuloma formation is one of the most important pathological features of human Crohn's disease. Mizoguchi et al. demonstrated that F4 / 80-positive immature CD11c + Dendritic cells (DCs) produce IL-23 and contribute to granuloma formation in a murine model of colitis (Mizoguchi et al., 2007). Th1 immune responses are prominent in Crohn's disease. In fact, CD4+ in the LPs of Crohn's disease... + T cells express T-bet and produce large amounts of interferon (IFN)-γ (Matsuoka et al., 2004). Sakuraba et al. demonstrated that dendritic cells (DCs) in the mesenteric lymph nodes of patients with Crohn's disease strongly promote Th1 and Th17 immune responses (Sakuraba et al., 2009). Mesenteric lymph node DCs contribute to the pathogenesis of IBD, particularly Crohn's disease.

[0066] The role of cytokines in diseases and symptoms

[0067] See Muzes et al., World J Gastroenterol, 7 November 2012; 18(41): 5848-586l ISSN 1007-9327 (print) ISSN 2219-2840 (online), “Changes of the cytokine profile ininflammatory bowel diseases”.

[0068] Cytokines are essential signaling agents of the mucosa-associated immune system for maintaining normal intestinal homeostasis. Imbalances in their pro-inflammatory characteristics can lead to disease states, such as those observed in inflammatory bowel disease (IBD), for example, Crohn's disease (CD) and ulcerative colitis (UC). The roles of pro-inflammatory cytokines such as IL-1α, IL-1β, IL-2, -6, -8, -12, -17, -23, IFN-γ, or TNFα in IBD are associated with the occurrence and progression of UC and CD. CD is often described as a prototype of T-helper cell (Th)1-mediated disease because the main inflammatory mediators are Th1 cytokines such as interleukin (IL)-12, interferon (IFN)-γ, and tumor necrosis factor (TNF)-α.

[0069] The binding of TNF-like ligands to their receptors triggers intracellular pathways directly involved in cell proliferation, differentiation, and survival. Most members of the TNF / TNF receptor protein superfamily are expressed on immune cells and play key roles in multiple components of the immune response. TNF-α is a major cytokine in the pathogenesis of IBD. It exerts its pleiotropic effects through the expression of adhesion molecules, fibroblast proliferation, procoagulant factors, and the induction of cytotoxicity, apoptosis, and acute phase responses. In IBD, TNF-α is derived from innate immune cells, such as macrophages or monocytes, and can also be differentiated Th1 cells. Serum levels of TNF-α are associated with clinical activity in UC and CD

[31] . It plays a coordinating role in chronic inflammation in IBD. The role of TNF-α in CD has been extensively studied. TNF-α binds to serum soluble TNF receptors 1 and 2 (sTNFR1 and 2) to trigger pro-inflammatory signaling. The levels of sTNFR1 and 2 are elevated in CD.

[0070] Tumor necrosis factor-like factor (TL1A), another member of the TNF family, stimulates IFN-γ secretion by binding to death receptor 3 (DR3). DR3 is expressed at high rates by cells from mucosal biopsies of UC and CD, and elevated IFN-γ levels are observed in IBD patients along with disease activity. The TL1A / DR3 system is involved in the pathogenesis of CD. Macrophages in the lamina propria are the main producers of TL1A, and its expression is significantly enhanced in CD. TL1A and IL-23 have been found to synergistically promote IFN-γ production by mucosal T cells. IFN-γ: Produced by TH1 T cells. IFN-γ is produced once inflammation is triggered and subsequently acts through various molecules and pathways of the immune system to exacerbate the inflammatory process. A large body of literature extensively documents the pro-inflammatory properties of IFN-γ, leading to the mainstream view that IFN-γ is a major pro-inflammatory cytokine in inflammatory and autoimmune diseases. Interferon-γ is causally involved in experimental inflammatory bowel disease in mice (Ito et al., Clinical and Experimental Immunology (2006), 146:330-338). Studies have clearly demonstrated that IFN-γ is involved in the development of inflammatory bowel disease in mice in terms of the degree of weight loss, DAI, histological score, and MPO activity. - / - Mice showed reduced colitis after DSS stimulation. Increased IFN-γ was produced in the colon of wild-type (WT) mice treated with DSS exhibiting severe IBD-like symptoms.

[0071] Interleukin-2 (IL-2) is produced by T cells and is crucial for T cell differentiation into effector T cells. IL-2 is also important for T cell proliferation. This is important for IBD because effector T cells are considered the primary cell type causing damage in IBD.

[0072] IL-8 (interleukin-8; aka CXCL8) primarily mediates neutrophil activation and migration to tissues and sites of inflammation originating from peripheral blood. Tissue levels of IL-8 have been found to be higher in active ulcerative colitis (UC) compared to normal colon tissue, and its serum concentrations have been correlated with endoscopic and histological severity of UC. IL-8 is important for inflammatory conditions and cancer (see, e.g., “The Chemokine CXCL8 in Carcinogenesis and Drug Response”, ISRN Oncol. 2013 Oct 9; 2013: 859154; Gales D et al., and Future Oncol, 2010 Jan; 6(1): 111-6. doi: 10.2217 / fbn.09.128; “CXCL8 and its cognate receptors in melanomaprogression and metastasis”, Singh S et al.). Particularly in cancer, IL-8 is also thought to play a role by supporting angiogenesis.

[0074] In any mode, aspect or instance of this document, the antibody or fragment antagonizes the binding of hOX40L to OX40.

[0458] As illustrated in the examples, the inventors devised a series of criteria that are particularly useful for identifying the antibodies and fragments of the present invention. These criteria are: -

[0459] (a) The ability of the antibody or fragment described in the HTRF assay to bind to cell surface hOX40L on CHO-S cells (optionally transfected with full-length human OX40L) and / or to bind to recombinant hOX40L;

[0460] (b) The ability of the antibody or fragment to neutralize human OX40 (e.g., neutralize the binding of human OX40L to the human OX40 receptor) in receptor and HTRF assays and / or flow cytometry receptor and assays; and

[0461] (c) The ability of the antibody or fragment to specifically bind to human and rhesus monkey OX40L (useful, enabling the evaluation of the PK, PD, efficacy and other parameters of the antibody or fragment in a rhesus monkey model as a human substitute).

[0462] Therefore, in one embodiment of the present invention, the antibody or fragment satisfies criteria (a), (b) and (c).

[0463] In one instance, a criterion (a) is set such that FACS assays show <70% receptor binding to hOX40L expressed on CHO-S cells.

[0464] In one instance, a standard (a) is set such that the antibody or fragment shown in an HTRF assay exhibits <90% receptor binding to OX40L.

[0465] In one instance, a standard (a) is set such that the antibody or fragment shows at least 20% efficacy in an HTRF assay.

[0466] In one instance, OX40 is used in standard (b).

[0467] In one embodiment, the assay or test of the antibody or fragment of the present invention is performed at or substantially at pH 7 (e.g., for in vitro assays and determinations) and at or substantially at room temperature.

[0468] Optionally, the antibody or fragment specifically binds to hOX40L, for example, under the SPR conditions disclosed herein, by SPR determination, with an affinity (apparent affinity, Kd) below 1 μM, ranging from 1000 nM to 100 nM, 100 nM to 10 nM, 10 nM to 1 nM, 1000 pM to 500 pM, 500 pM to 200 pM, below 200 pM, ranging from 200 pM to 150 pM, 200 pM to 100 pM, 100 pM to 10 pM, 10 pM to 1 pM, for example, in the range of 1 mM to 1 pM (e.g., 1 mM to 100 pM; 10 nM to 100 pM; 1 nM to 10 pM; or 100 pM to 1 pM). Alternatively or additionally, the antibody or fragment specifically binds to rhesus monkey OX40L, for example, under the SPR conditions disclosed herein, by an SPR assay, with an affinity (apparent affinity, Kd) below 1 μM, ranging from 1000 nM to 100 nM, 100 nM to 10 nM, 10 nM to 1 nM, 1000 pM to 500 pM, 500 pM to 200 pM, below 200 pM, ranging from 200 pM to 150 pM, 200 pM to 100 pM, 100 pM to 10 pM, 10 pM to 1 pM, for example, in the range of 1 mM to 1 pM (e.g., 1 mM to 100 pM; 10 nM to 100 pM; 1 nM to 10 pM; or 100 pM to 1 pM). Such binding measurements can be performed using various binding assays known in the art, such as surface plasmon resonance (SPR), for example using Biacore. TM Or use ProteOn XPR36 TM (Bio- ),use (Sapidyne Instruments, Inc.) or use ForteBio Octet (Pall ForteBio Corp.).

[0469] OX40L binding capacity, specificity, and affinity (Kd, K off and / or K on This can be determined by any conventional method in the art, such as surface plasmon resonance (SPR). The term "Kd," as used herein, is intended to refer to the equilibrium dissociation constant of a particular antibody-antigen interaction.

[0470] In one embodiment, surface plasmon resonance (SPR) is performed at 25°C. In another embodiment, SPR is performed at 37°C.

[0471] In one implementation, SPR is performed at a physiological pH, such as about pH 7 or at pH 7.6 (e.g., using Hepes buffered saline at pH 7.6, also known as HBS-EP).

[0472] In one implementation, SPR is performed at physiological saline levels, such as 150 mM NaCl.

[0473] In one embodiment, SPR is at a detergent level not exceeding 0.05% by volume, for example at 0.05% of P20 (polysorbate 20; for example, Tween-20). TM (Tween-20 TM The procedure was carried out in the presence of 3 mM EDTA.

[0474] In one example, SPR was performed at 25°C or 37°C in a buffer solution at pH 7.6, 150 mM NaCl, 0.05% detergent (e.g., P20), and 3 mM EDTA. The buffer solution may contain 10 mM Hepes. In another example, SPR was performed at 25°C or 37°C in an HBS-EP. HBS-EP is available from Teknova Inc. (Califomia; catalog number H8022).

[0475] In one instance, the affinity of the antibody or fragment was determined using SPR in the following manner:

[0476] 1. For example, by primary amine coupling to match the constant region of anti-mouse (or other relevant human, rat, or non-human vertebrate antibody species) IgG (e.g., Biacore) TM BR-1008-38) is coupled to a biosensor chip (e.g., a GLM chip);

[0477] 2. Expose anti-mouse IgG (or other matching species antibody) to the test IgG antibody to capture the test antibody on the chip;

[0478] 3. Pass the test antigen through the capture surface of the chip at 1024 nM, 256 nM, 64 nM, 16 nM, 4 nM, and 0 nM (i.e., separate buffer solutions); and

[0479] 4. For example, under the SPR conditions discussed above (e.g., in physiological buffer at 25°C), the binding affinity of the test antibody to the test antigen is determined using surface plasmon resonance. Any standard SPR apparatus can be used, such as Biacore. TM Or use ProteOn XPR36 TM (Bio- Perform SPR.

[0480] Regeneration of the captured surface can be performed using 10 mM glycine at pH 1.7. This removes the captured antibody and makes the surface available for another interaction. Standard techniques, such as those using ProteOn XPR36, can be used. TM The analysis software's inherent model will be fitted to the data to form a 1:1 inherent model.

[0481] In one example, the antibody or fragment of the present invention is contained in a medical container, such as a vial, syringe, IV container, or injection device (e.g., intraocular or intravitreal injection device). In one example, the antibody or fragment is in vitro, for example, in a sterile container. In one example, the present invention provides a kit comprising the antibody or fragment of the present invention, packaging, and instructions for use in humans for the treatment, prevention, or diagnosis of OX40L-mediated diseases or symptoms. In one example, the instructions indicate that the OX40L variant sequence of the present invention should be genotyped in humans before administration of the antibody or fragment. In one example, the instructions indicate that the OX40L variant of the present invention should be phenotypically analyzed in humans before administration of the antibody or fragment. In one example, the human is Chinese (e.g., Han or CHS) and the instructions are in Chinese (e.g., Mandarin).

[0482] In one instance, the binding sites of the antibody or fragment are selected from multiple binding sites (e.g., a library). For example, the multiple binding sites comprise or consist of multiple 4-chain antibodies or fragments thereof, such as dAb, Fab, or scFv. Suitable methods for generating multiple binding sites for screening include phage display (generating a phage display library of antibody binding sites), ribosome display (generating a ribosome display library of antibody binding sites), yeast display (generating a yeast display library of antibody binding sites), or immunization of non-human vertebrates (e.g., rodents, such as mice or rats, e.g., Velocimouse) with hOX40L or hOX40L epitopes. TM Kymouse TM Xenomouse TM Aliva Mouse TM HuMab Mouse TM Omnimouse TM Omnirat TM Or MeMo Mouse TM And antibody-generating cell libraries (e.g., B cell, plasma cell, or plasmablastic cell libraries) and / or libraries of isolated antibodies, fragments, or binding sites.

[0483] The term "epitope" is a region of an antigen that is bound to an antibody or fragment. Epitopes can be defined as structural or functional. Functional epitopes are typically subsets of structural epitopes and contain residues that directly contribute to the affinity of the interaction. Epitopes can also be conformational, i.e., composed of nonlinear amino acids. In some embodiments, epitopes may include determinants that are chemically active surface molecules, such as amino acids, sugar side chains, phosphoryl groups, or sulfonyl groups, and in some embodiments, may have specific three-dimensional structural features and / or specific charge features.

[0484] With respect to any aspect of the invention, the term "isolated," for example, of an antibody or fragment, means that the tested antibody or fragment (1) does not contain at least some other proteins that would normally be found with it, (2) is substantially free of other proteins from the same source, such as from the same species, (3) is expressed by cells from a different species, (4) has been separated from at least about 50% of the polynucleotides, lipids, carbohydrates or other substances associated with it in nature, (5) is operatively associated with polypeptides (through covalent or non-covalent interactions) that are not associated with it in nature, or (6) is not found in nature. Typically, "isolated" antibodies, fragments, etc., constitute at least about 5%, at least about 10%, at least about 25%, or at least about 50%, 60%, 70%, 80%, 85%, 90%, 92%, 95%, 97%, 98%, 99%, or >99% of a given sample. Such isolated antibodies, fragments, etc., may be encoded by genomic DNA, cDNA, mRNA or other RNA of synthetic origin or any combination thereof. Preferably, the isolated antibodies, fragments, etc., are substantially free of proteins or peptides or other contaminants found in their natural environment that would interfere with their therapeutic, diagnostic, preventative, research, or other uses.

[0485] For example, an “isolated” antibody is an antibody that has been identified as being separated and / or recovered from components of its production environment (e.g., naturally or recombinantly). Preferably, the isolated peptide does not associate with any other components from its production environment, for example, such that the antibody has been isolated to FDA-approved or approved standards. Contaminant components of its production environment, such as contaminants generated by recombinant transfected cells, are substances that typically interfere with the research, diagnostic, or therapeutic use of the antibody and may include enzymes, hormones, and other proteins or non-protein solutes. In a preferred embodiment, the peptide will be purified to: (1) greater than 95% by weight of antibody, and in some embodiments, greater than 99% by weight of antibody, for example, by Lowry assay; (2) sufficient to obtain at least 15 residues of the N-terminal or internal amino acid sequence using a turn-cup sequencer; or (3) homogeneity achieved by SDS-PAGE under non-reducing or reducing conditions using Coomassie blue or, preferably, silver staining. Because at least one component of the antibody’s natural environment will be absent, isolated antibodies include in situ antibodies from recombinant cells. However, typically, isolated peptides or antibodies are prepared through at least one purification step.

[0486] Immunoconjugates

[0487] This invention covers antibodies or fragments conjugated to therapeutic components (“immunoconjugates”), such as cytotoxins, chemotherapeutic agents, immunosuppressants, or radioisotopes. Cytotoxic agents include any reagents that are harmful to cells. Examples of suitable cytotoxic agents and chemotherapeutic agents for forming immunoconjugates are known in the art, see, for example, WO 05 / 103081, which is incorporated herein by reference in its entirety.

[0488] Bispecific

[0489] The antibodies and fragments of the present invention can be monospecific, bispecific, or multispecific. A multispecific mAb may be specific to different epitopes of a target polypeptide or may contain antigen-binding domains specific to more than one target polypeptide. See, for example, Tutt et al., (1991) J. Immunol. 147: 60-69. Human anti-hOX40L antibodies or fragments may be linked to or co-expressed with another functional molecule, such as another peptide or protein. For example, an antibody or fragment thereof may be functionally linked to one or more other molecular entities, such as another antibody or antibody fragment (e.g., by chemical coupling, gene fusion, non-covalent association, or other means) to produce bispecific or multispecific antibodies with a second binding specificity.

[0490] Exemplary bispecific antibody forms that can be used in the context of this invention involve the use of a first immunoglobulin (Ig) CH3 domain and a second Ig CH3 domain, wherein the first and second Ig CH3 domains differ from each other by at least one amino acid, and the difference of at least one amino acid residue reduces the binding of the bispecific antibody to protein A compared to a bispecific antibody without amino acid residues. In one embodiment, the first Ig CH3 domain binds to protein A while the second Ig CH3 domain contains a mutation that reduces or eliminates protein A binding, such as an H95R modification (according to IMGT exon numbering; H435R, according to EU numbering). The second CH3 domain may also contain a Y96F modification (according to IMGT; Y436F, according to EU). Other modifications that may be found in the second CH3 include: D16E, L18M, N44S, K52N, V57M, and V821 (according to IMGT; D356E, L358M, N384S, K392N, V397M, and V422I, according to EU) in the case of IgG1 antibody; N44S, K52N, and V82I (according to IMGT; N384S, K392N, and V422I, according to EU) in the case of IgG2 antibody; and Q15R, N44S, K52N, V57M, R69K, E79Q, and V82I (according to IMGT; Q355R, N3845, K392N, V397M, R409K, E419Q, and V422I, according to EU) in the case of IgG4 antibody. These modifications to the form of the bispecific antibodies are covered within the scope of this invention.

[0494] In some embodiments, the antibody competitively (e.g., in a dose-dependent manner) binds to hOX40L, such as cell surface-expressed hOX40L or soluble hOX40L, against OX40 or its fusion protein (e.g., Fc:OX40). Exemplary competitive blocking assays are provided in the embodiments herein.

[0495] On the other hand, this article provides isolated nucleic acids that encode antibodies that bind to hOX40L peptides (e.g., cell surface-expressed or soluble hOX40L), hOX40L peptide fragments, or hOX40L epitopes. In some embodiments, the nucleic acid encodings are as disclosed in the sequence: VH strand, VL strand, VH domain, VL domain, HCDR1, HCDR2, HCDR3, LCDR1, LCDR2, and LCDR3 (i.e., Seq ID No. 30 or Seq ID No. 62 for the VH strand; Seq ID No. 32 or Seq ID No. 64 for the VL strand; Seq ID No. 2, Seq ID No. 34, Seq ID No. 66, or Seq ID No. 94 for the VH domain, especially Seq ID No. 34; Seq ID No. 16, Seq ID No. 48, Seq ID No. 80, or Seq ID No. 108 for the VL domain, especially Seq ID No. 48; Seq ID No. 4, Seq ID No. 10, Seq ID No. 36, Seq ID No. 42, and Seq ID No. 64 for the HCDR1). For HCDR2, the Seq ID No: 68, Seq ID No: 74, Seq ID No: 96, or Seq ID No: 102, especially Seq ID No: 36 or Seq ID No: 42; for HCDR2, the Seq ID No: 6, Seq ID No: 12, Seq ID No: 38, Seq ID No: 44, Seq ID No: 70, Seq ID No: 76, Seq ID No: 98, or Seq ID No: 104, especially Seq ID No: 38 or Seq ID No: 44; for HCDR3, the Seq ID No: 8, Seq ID No: 14, Seq ID No: 40, Seq ID No: 46, Seq ID No: 72, Seq ID No: 78, Seq ID No: 100, or Seq ID No: 106, especially Seq ID No: 40 or Seq ID No: 46; for LCDR1, the Seq ID No: 18, Seq ID No: 68, Seq ID No: 74, Seq ID No: 96, or Seq ID No: 102, especially Seq ID No: 36 or Seq ID No: 42; for HCDR2, the Seq ID No: 6, Seq ID No: 12, Seq ID No: 38, Seq ID No: 44, Seq ID No: 70, Seq ID No: 76, Seq ID No: 98, or Seq ID No: 104, especially Seq ID No: 38 or Seq ID No: 44; for HCDR3, the Seq ID No: 8, Seq ID No: 14, Seq ID No: 40, Seq ID No: 46, Seq ID No: 72, Seq ID No: 78, Seq ID No: 100, or Seq ID No: IDNo: 24, SeqIDNo: 50, SeqID No: 56, Seq ID No: 82, Seq ID No: 88, Seq ID No: 110 or Seq ID No: 116, especially Seq ID No: 50 or Seq ID No: 56;For LCDR2, SeqIDNo: 20, SeqIDNo: 26, SeqIDNo: 52, SeqIDNo: 58, SeqIDNo: 84, SeqIDNo: 90, SeqIDNo: 112, or SeqIDNo: 118, especially Seq ID No: 52 or Seq ID No: 58; and for LCDR3, Seq ID No: 22, Seq ID No: 28, Seq ID No: 54, Seq ID No: 60, Seq ID No: 86, Seq ID No: 92, Seq ID No: 114, or Seq IDNo: 120, especially Seq ID No: 54 or Seq ID No: 60).

[0496] On the other hand, this article provides vectors and host cells containing nucleic acids encoding antibodies or fragments of the present invention.

[0497] In some embodiments, the antibody specifically binds to one or more single nucleotide polymorphism (SNP) variants of hOX40L. In examples of any aspect of the invention, hOX40L is a trimer of the monomer.

[0498] On the one hand, this article provides a method for reducing (e.g., at least 20, 30, 40, 50, or 60%, or 70%, 80%, 90%, 95%, or >90%) or completely inhibiting the binding of hOX40L to OX40 in a subject (e.g., a human subject), comprising administering to the subject an effective amount of an antibody or fragment thereof of the present invention that specifically binds to hOX40L (e.g., cell surface-expressed or soluble hOX40L).

[0499] On one hand, this article provides a method for treating or preventing hOX40L-mediated diseases or conditions in a subject (e.g., a human subject), the method comprising administering to the subject an effective amount of an antibody or fragment of the present invention that specifically binds to hOX40L (e.g., cell surface-expressed or soluble hOX40L), wherein the disease or condition is treated or prevented by said antibody or fragment. In one example, the method comprises reducing or inhibiting the secretion of one, more, or all of the subject's hOX40L bioactivity, such as IL-2, IL-8, TNFα, and interferon γ. In one example, the bioactivity is selected from the secretion of one, more, or all of IL-2, TNFα, and interferon γ. In one example, the bioactivity is selected from the secretion of one, more, or all of IL-8, CCL20, and RANTES.

[0500] On one hand, this article provides a method for reducing or inhibiting the secretion of one, more, or all of the hOX40L biological activity, such as IL-2, IL-8, TNFα, and interferon γ, in a subject (e.g., a human subject). The method comprises administering to the subject an effective amount of an antibody or fragment of the present invention that specifically binds to hOX40L (e.g., cell surface-expressed or soluble hOX40L), wherein the hOX40L biological activity is reduced by said antibody or fragment. In one example, the biological activity is selected from the secretion of one, more, or all of IL-2, TNFα, and interferon γ. In another example, the biological activity is selected from the secretion of one, more, or all of IL-8, CCL20, and RANTES.

[0501] The term “about” or “approximately” means within 20%, preferably 10%, and more preferably 5% (or 4%, 3%, or 2%, or in one instance 1% or less) of a given value or range.

[0502] As used herein, “administration” means the act of injecting or otherwise physically delivering a substance (e.g., the anti-hOX40L antibody provided herein) into a patient as it is present in vitro, such as via mucosal, intradermal, intravenous, intramuscular delivery, and / or any other physical delivery method described herein or known in the art. In treating a disease or its symptoms, administration of a substance is typically performed after the onset of the disease or its symptoms. In preventing a disease or its symptoms, administration of a substance is typically performed before the onset of the disease or its symptoms.

[0503] To determine the percentage identity of two amino acid sequences or two nucleic acid sequences, the sequences are aligned for optimal comparison purposes (e.g., vacancies may be introduced in the first amino acid or nucleic acid sequence to achieve optimal alignment with the second amino acid or nucleic acid sequence). The amino acid residues or nucleotides at the corresponding amino acid or nucleotide positions are then compared. The molecules are identical at that position when a position in the first sequence is occupied by the same amino acid residue or nucleotide at the corresponding position in the second sequence. The percentage identity between two sequences is a function of the number of shared positions (i.e., identity % = identical overlapping positions / total number of positions × 100%). In one embodiment, the two sequences are of the same length.

[0504] The determination of percentage identity between two sequences (e.g., amino acid sequences or nucleic acid sequences) can also be achieved using mathematical algorithms. Preferred, non-limiting examples of mathematical algorithms for comparing two sequences are those described in Karlin and Altschul, 1990, Proc. Natl. Acad. Sci. USA 87: 2264-2268, modified as described in Karlin and Altschul, 1993, Proc. Natl. Acad. Sci. USA 90: 5873-5877. Such algorithms are incorporated into the NBLAST and XBLAST procedures of Altschul et al., 1990, J. Mol. Biol. 215: 403. BLAST nucleotide searches can be performed using NBLAST nucleotide procedure parameters set, for example, score = 100, word length = 12, to obtain nucleotide sequences homologous to the nucleic acid molecules of the present invention. BLAST protein searches can be performed using XBLAST procedure parameters set, for example, score = 50, word length = 3, to obtain amino acid sequences homologous to the protein molecules of the present invention. To obtain vacancy alignments for comparative purposes, vacancy BLAST can be used, as described in Altschul et al., 1997, Nucleic Acids Res. 25: 3389 3402. Alternatively, PSIBLAST can be used for an iterative search to detect distant relationships between molecules (Id.). When using the BLAST, vacancy BLAST, and PSI BLAST programs, the default parameters of each program (e.g., XBLAST and NBLAST) can be used (see, for example, the National Center for Biotechnology Information (NCBI) on the World Wide Web, ncbi.nlm.nih.gov). Another preferred, non-limiting example of a mathematical algorithm for sequence alignment is the algorithm of Myers and Miller, 1988, CABIOS 4: 11 17. Such algorithms are incorporated into the ALIGN program (version 2.0), which is part of the GCG sequence alignment software package. When comparing amino acid sequences using the ALIGN program, the PAM120 weighted residue table, a vacancy length penalty of 12, and a vacancy penalty of 4 can be used.

[0505] Similar techniques to those described above can be used to determine the percentage identity between two sequences, allowing or disallowing gaps. In calculating percentage identity, typically only exact matches are counted.

[0506] As used herein, an "antagonist" or "inhibitor" of hOX40L refers to a ligand (e.g., an antibody or fragment) capable of inhibiting or otherwise reducing, for example, the biological activity of hOX40L in cells expressing hOX40L or in cells expressing hOX40L ligands. For example, in some embodiments, the antibody of the present invention is an antagonist that inhibits or otherwise reduces the secretion of CCL20, IL-8, and / or RANTES from cells having OX40 expressed on their cell surface (when the antibody is contacted with the cells). In some embodiments, an antagonist of hOX40L (e.g., the antagonistic antibody of the present invention) may, for example, act by inhibiting or otherwise reducing the activation and / or cell signaling pathways of cells expressing OX40L, thereby inhibiting the hOX40L-mediated biological activity of cells relative to the biological activity of hOX40L in the absence of the antagonist. In some embodiments, the antibody provided herein is a fully human, antagonistic anti-hOX40L antibody, preferably a fully human, monoclonal, antagonistic anti-hOX40L antibody.

[0507] The terms "antibody" and "immunoglobulin" or "Ig" are used interchangeably herein. Antibodies or fragments thereof that specifically bind to the hOX40L antigen may cross-react with the relevant antigen. Preferably, antibodies or fragments thereof that specifically bind to the hOX40L antigen do not cross-react with other antigens (but may optionally cross-react with OX40L from different species, such as rhesus monkeys or mice). Antibodies or fragments thereof that specifically bind to the hOX40L antigen can be assessed, for example, by immunoassay, BIAcore, etc. TM Or other techniques known to those skilled in the art for identification. An antibody or fragment thereof specifically binds to the hOX40L antigen when it binds to the hOX40L antigen with a higher affinity than to any cross-reactive antigen, as measured using experimental techniques such as radioimmunoassay (RIA) and enzyme-linked immunosorbent assay (ELISA). Typically, the specific or selective reaction will be at least twice the background signal or noise, and more often more than 10 times the background. For a discussion of antibody specificity, see, for example, Paul ed., Fundamental Immunology 2nd ed., 1989, Raven Press, New York, pp. 332-336.

[0508] The antibodies of the present invention include, but are not limited to, synthetic antibodies, monoclonal antibodies, recombinant antibodies, multispecific antibodies (including bispecific antibodies), human antibodies, humanized antibodies, chimeric antibodies, intracellular antibodies, single-chain Fvs (scFv) (e.g., including monospecific, bispecific, etc.), camelified antibodies, Fab fragments, F(ab′) fragments, disulfide-linked Fvs (sdFv), anti-idiotype (anti-Id) antibodies, and epitope-binding fragments of any of the above. Specifically, the antibodies of the present invention comprise immunoglobulin molecules and immunologically active portions of immunoglobulin molecules, i.e., antigen-binding domains or molecules containing antigen-binding sites that specifically bind to hOX40L antigens (e.g., one or more complementarity-determining regions (CDRs) of anti-hOX40L antibodies). The antibodies of the present invention can be any type (e.g., IgG, IgE, IgM, IgD, IgA, and IgY), any class (e.g., IgG1, IgG2, IgG3, IgG4, IgA1, and IgA2, especially IgG4), or any subclass (e.g., IgG2a and IgG2b) of immunoglobulin molecules. In a preferred embodiment, the hOX40L antibody is fully human, such as a fully human monoclonal hOX40L antibody. In some embodiments, the antibodies of the present invention are IgG antibodies, or one of their classes (e.g., human IgG1 or IgG4) or subclasses. In some embodiments, the antibodies of the present invention contain a human γ4 constant region. In another embodiment, the heavy chain constant region does not bind to the Fc-γ receptor and, for example, contains the Leu235Glu mutation. In another embodiment, the heavy chain constant region contains the Ser228Pro mutation to increase stability. In another embodiment, the heavy chain constant region is IgG4-PE.

[0509] The terms "antigen-binding domain," "antigen-binding region," "antigen-binding fragment," and similar terms refer to an antibody moiety (e.g., a complementarity-determining region (CDR)) containing amino acid residues that interact with the antigen and confer specificity and affinity to the antigen upon the binder. The antigen-binding region can be derived from any animal species, such as rodents (e.g., rabbits, rats, or hamsters) and humans. Preferably, the antigen-binding region will be of human origin.

[0510] As used herein, the term "composition" is intended to cover products containing (optionally) specified amounts of specified ingredients (e.g., antibodies of the present invention), and products directly or indirectly produced by combinations of (optionally) specified amounts of specified ingredients.

[0511] In the case of peptides, as used herein, the term "derivative" refers to a peptide comprising an hOX40L peptide, an hOX40L peptide fragment, or an antibody that specifically binds to an hOX40L peptide, the amino acid sequence of which has been altered by introducing substitutions, deletions, or additions of amino acid residues. As used herein, the term "derivative" refers to, for example, an hOX40L peptide, an hOX40L peptide fragment, or an antibody that specifically binds to an hOX40L peptide, which has been chemically modified by covalently linking the peptide to any type of molecule. For example, but not in a limited manner, the hOX40L peptide, hOX40L peptide fragment, or hOX40L antibody may be chemically modified by glycosylation, acetylation, polyethylene glycolation, phosphorylation, amidation, derivatization with known protecting / capping groups, proteolytic cleavage, linking to cellular ligands or other proteins, etc. Derivatives may be modified at the type or position of the linked molecule in a manner different from that of naturally occurring or initiating peptides or peptides. Derivatives also include the deletion of one or more chemical groups naturally present on said peptide or peptide. Derivatives of hOX40L peptides, hOX40L peptide fragments, or hOX40L antibodies can be chemically modified using techniques known to those skilled in the art, including but not limited to specific chemical cleavage, acetylation, formulation, and metabolic synthesis of tunicamycin. Furthermore, the derivatives of hOX40L peptides, hOX40L peptide fragments, or hOX40L antibodies may contain one or more non-classical amino acids. The peptide derivatives have similar or identical functions to the hOX40L peptides, hOX40L peptide fragments, or hOX40L antibodies described herein.

[0512] As used herein, the term "effective amount" refers to an amount of therapy (e.g., the antibody or pharmaceutical composition provided herein) sufficient to reduce and / or improve the severity and / or duration of a given disease and / or associated symptoms. The term also covers amounts necessary to reduce or improve the progression or development of a given disease, reduce or improve relapses, development, or onset of a given disease, and / or enhance or strengthen the preventive or therapeutic effect of another therapy (e.g., a therapy other than the anti-hOX40L antibody provided herein). In some embodiments, the effective amount of the antibody of the present invention is from about 0.1 mg / kg (mg antibody / kg subject weight) to about 100 mg / kg. In some embodiments, the effective amount of the antibody provided is about 0.1 mg / kg, about 0.5 mg / kg, about 1 mg / kg, 3 mg / kg, 5 mg / kg, about 10 mg / kg, about 15 mg / kg, about 20 mg / kg, about 25 mg / kg, about 30 mg / kg, about 35 mg / kg, about 40 mg / kg, about 45 mg / kg, about 50 mg / kg, about 60 mg / kg, about 70 mg / kg, about 80 mg / kg, about 90 mg / kg, or about 100 mg / kg (or a range thereof). In some embodiments, as used herein, “effective amount” also refers to the amount of the antibody of the present invention used to achieve a specified result (e.g., inhibition of cellular hOX40L biological activity, such as inhibition of CCL20, IL-8, or RANTES, or INF-γ, TNF-α, or IL-2, especially INF-γ secreted from cells).

[0513] As used herein, the term "epitope" refers to a localized region on the surface of an antigen, such as an hOX40L polypeptide or a fragment of hOX40L polypeptide, which is capable of being bound by one or more antigen-binding regions of an antibody and has antigenic or immunogenic activity in animals, preferably mammals and most preferably humans, capable of inducing an immune response. An epitope with immunogenic activity is a portion of a polypeptide that induces an antibody response in an animal. An epitope with antigenic activity is a portion of a polypeptide specifically bound by an antibody by any method well known in the art, such as by an immunoassay described herein. An antigenic epitope is not necessarily immunogenic. Epitopes typically consist of chemically active surface molecules such as amino acids or sugar side chains and have specific three-dimensional structural features and specific charge features. The polypeptide region contributing to the epitope may be a continuous amino acid of the polypeptide or the epitope may be derived together from two or more discontinuous regions of the polypeptide. An epitope may or may not be a three-dimensional surface feature of an antigen. In some embodiments, an hOX40L epitope is a three-dimensional surface feature of an hOX40L polypeptide (e.g., in the form of a trimer of the hOX40L polypeptide). In other embodiments, the hOX40L epitope is a linear characteristic of the hOX40L polypeptide (e.g., in trimer or monomeric form). The antibodies provided herein can specifically bind to the epitope in the monomeric (denatured) form of hOX40L, the epitope in the trimeric (natural) form of hOX40L, or the epitope in both the monomeric (denatured) and trimeric (natural) forms of hOX40L. In a specific embodiment, the antibodies provided herein specifically bind to the epitope in the trimeric form of hOX40L, but not specifically to the monomeric form of hOX40L.

[0514] As used herein, the term "excipient" refers to an inert substance commonly used as a diluent, medium, preservative, binder, or stabilizer in pharmaceuticals and includes, but is not limited to, proteins (e.g., serum albumin), amino acids (e.g., aspartic acid, glutamic acid, lysine, arginine, glycine, histidine, etc.), fatty acids and phospholipids (e.g., alkyl sulfonates, caprylates, etc.), surfactants (e.g., SDS, polysorbates, nonionic surfactants, etc.), sugars (e.g., sucrose, maltose, trehalose, etc.), and polyols (e.g., mannitol, sorbitol, etc.). See also Remington's Pharmaceutical Sciences (1990), Mack Publishing Co., Easton, Pa., which is incorporated herein by reference in its entirety.

[0515] In the case of peptides or polypeptides, the term "fragment" as used herein refers to a peptide or polypeptide containing less than the full-length amino acid sequence. Such fragments can be generated, for example, by truncation at the amino terminus, truncation at the carboxyl terminus, and / or deletion of residues from the interior of the amino acid sequence. Fragments can be generated, for example, by selective RNA splicing or in vivo protease activity. In some embodiments, the hOX40L fragment comprises a polypeptide comprising an amino acid sequence of at least 5 consecutive amino acid residues, at least 10 consecutive amino acid residues, at least 15 consecutive amino acid residues, at least 20 consecutive amino acid residues, at least 25 consecutive amino acid residues, at least 40 consecutive amino acid residues, at least 50 consecutive amino acid residues, at least 60 consecutive amino acid residues, at least 70 consecutive amino acid residues, at least 80 consecutive amino acid residues, at least 90 consecutive amino acid residues, at least 100 consecutive amino acid residues, at least 125 consecutive amino acid residues, at least 150 consecutive amino acid residues, at least 175 consecutive amino acid residues, at least 200 consecutive amino acid residues, or at least 250 consecutive amino acid residues. In one specific embodiment, the fragment of the hOX40L polypeptide or antibody that specifically binds to the hOX40L antigen retains at least one, at least two, or at least three functions of the polypeptide or antibody.

[0516] The terms “fully human antibody” or “human antibody” are used interchangeably herein and refer to an antibody that comprises a human variable region and, most preferably, a human constant region. In specific embodiments, the term refers to an antibody comprising both a human-derived variable region and a constant region. In some embodiments, a “fully human” anti-hOX40L antibody may also encompass an antibody that binds to an hOX40L polypeptide and is encoded by a nucleic acid sequence of a somatic variant of a human germline immunoglobulin nucleic acid sequence. In one specific embodiment, the anti-hOX40L antibody provided herein is a fully human antibody. The term “fully human antibody” includes antibodies having variable and constant regions corresponding to human germline immunoglobulin sequences, as described by Kabat et al. (See Kabat et al. (1991) Sequences of Proteins of Immunological Interest, 5th ed., Department of Health and Human Services, NIH Publication 91-3242). For example, exemplary methods for generating fully human antibodies are provided in the embodiments herein, but any method known in the art may be used.

[0517] The phrase “recombinant human antibody” includes human antibodies prepared, expressed, produced, or isolated in a recombinant manner, such as antibodies expressed using a recombinant expression vector transfected into host cells, antibodies isolated from recombinant or combined human antibody libraries, antibodies isolated from transgenic and / or transchromosomal animals (e.g., mice or cattle) that are transgenic with respect to the human immunoglobulin gene (see, for example, Taylor, LD et al. (1992) Nucl. Acids Res. 20: 6287-6295), or antibodies prepared, expressed, produced, or isolated by any other means involving splicing a human immunoglobulin gene sequence onto another DNA sequence. Such recombinant human antibodies may have variable and constant regions derived from human germline immunoglobulin sequences (see Kabat, EA et al. (1991) Sequences of Proteins of Immunological Interest, 5th ed., Department of Health and Human Services, NIH Publication No. 91-3242). However, in some implementations, such recombinant human antibodies are subjected to in vitro mutagenesis (or, when using animals that are transgenic for human Ig sequences, in vivo somatic cell mutagenesis), and therefore the amino acid sequences of the VH and VL regions of the recombinant antibody, although derived from and associated with human germline VH and VL sequences, are not sequences that are naturally present in the in vivo human antibody germline library.

[0518] As used herein, the term "fusion protein" refers to a polypeptide comprising the amino acid sequence of an antibody and the amino acid sequence of a heterologous peptide or protein (i.e., a peptide or protein that is not typically part of an antibody (e.g., a non-anti-hOX40L antigen antibody). The term "fusion," when used with respect to hOX40L or anti-hOX40L antibodies, refers to the linking of a peptide or polypeptide or fragment thereof, variant, and / or derivative thereof to a heterologous peptide or polypeptide. Preferably, the fusion protein retains the biological activity of the hOX40L or anti-hOX40L antibody. In some embodiments, the fusion protein comprises an hOX40L antibody VH domain, a VL domain, VH CDRs (one, two, or three VH CDRs), and / or VL CDRs (one, two, or three VL CDRs), wherein the fusion protein specifically binds to the hOX40L epitope.

[0519] The term "heavy chain," when used in relation to antibodies, refers to the amino acid sequence based on the heavy chain constant domain, designated as five distinct types: α, δ, ε, γ, and μ. These different types of heavy chains are well-known and generate five classes of antibodies: IgA, IgD, IgE, IgG, and IgM, including four subclasses of IgG: IgG1, IgG2, IgG3, and IgG4. Preferably, the heavy chain is a human heavy chain. In one instance, the heavy chain is a disabling IgG isotype, such as disabling IgG4. In some embodiments, the antibodies of the present invention contain a human γ4 constant region. In another embodiment, the heavy chain constant region does not bind to the Fc-γ receptor and, for example, contains the Leu235Glu mutation. In another embodiment, the heavy chain constant region contains the Ser228Pro mutation to increase stability. In yet another embodiment, the heavy chain constant region is IgG4-PE.

[0520] As used herein, the term "host" refers to an animal, preferably a mammal, and more preferably a human.

[0521] As used in this article, the term "host cell" refers to a specific test cell transfected with a nucleic acid molecule and its progeny or potential progeny. Due to mutations that may occur in the next generation, environmental influences, or the integration of nucleic acid molecules into the host cell genome, the progeny of such cells may differ from the transfected parent cell.

[0522] As used herein, the term "immunomodulator" and its variations, including but not limited to immunomodulators, refers to agents that modulate the host's immune system. In some embodiments, the immunomodulator is an immunosuppressant. In some other embodiments, the immunomodulator is an immunostimulant. According to the present invention, the immunomodulators used in the combination therapies of the present invention do not include anti-hOX40L antibodies or antigen-binding fragments. Immunomodulators include, but are not limited to, small molecules, peptides, polypeptides, proteins, fusion proteins, antibodies, inorganic molecules, mimics, and organic molecules.

[0523] As used herein, the term "combination" in the context of administering other therapies means the use of more than one therapy. The use of the term "combination" does not restrict the order in which therapies are administered to the infected subject. The first therapy may be administered before (e.g., 1 minute, 45 minutes, 30 minutes, 45 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours, 24 hours, 48 ​​hours, 72 hours, 96 hours, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 8 weeks, or 12 weeks), simultaneously with (e.g., 1 minute, 45 minutes, 30 minutes, 45 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours, 24 hours, 48 ​​hours, 72 hours, 96 hours, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 8 weeks, or 12 weeks) the second therapy is administered to a subject who has, has, or is susceptible to hOX40L-mediated disease. Any additional therapy may be administered in any order along with other additional therapies. In some embodiments, the antibodies of the present invention may be administered in combination with one or more therapies (e.g., therapies not of the present invention, but administered concurrently to prevent, treat, manage, and / or improve hOX40L-mediated disease). Non-limiting examples of therapies that may be administered in combination with the antibodies of the present invention include analgesics, anesthetics, antibiotics, or immunomodulators, or any other agents listed in the United States Pharmacopeia and / or the Physician's Desk Reference.

[0524] "Isolated" or "purified" antibodies (e.g.) are substantially free of cellular material or other contaminating proteins from the cell or tissue from which the antibody originates, or are substantially free of chemical precursors or other chemicals when synthesized by chemical methods. The term "substantially free of cellular material" includes antibody preparations in which the antibody is separated from the cellular components from which it is isolated, or produced by recombinant methods. Therefore, antibodies substantially free of cellular material include antibody preparations having less than about 30%, 20%, 10%, or 5% (by dry weight) of heterologous proteins (also referred to herein as "contaminating proteins"). When antibodies are produced by recombinant methods, they are also preferably substantially free of culture medium, i.e., the culture medium constitutes less than about 20%, 10%, or 5% of the volume of the protein preparation. When antibodies are produced by chemical synthesis, they are preferably substantially free of chemical precursors or other chemicals, i.e., separated from the chemical precursors or other chemicals involved in protein synthesis. Therefore, such antibody preparations have less than about 30%, 20%, 10%, or 5% (by dry weight) of chemical precursors or compounds other than the target antibody. In a preferred embodiment, the antibody of the present invention is isolated or purified.

[0525] "Isolated" nucleic acid molecules are nucleic acid molecules that are separated from other nucleic acid molecules present in natural sources of nucleic acid molecules. Furthermore, "isolated" nucleic acid molecules, such as cDNA molecules, may be substantially free of other cellular material or culture medium when produced by recombinant technology, or substantially free of chemical precursors or other chemicals when synthesized by chemical methods. In one specific embodiment, the nucleic acid molecule encoding the antibody of the present invention is isolated or purified.

[0526] The terms “human OX40L,” “hOX40L,” or “hOX40L polypeptide,” and similar terms refer to polypeptides that include a sequence listing and related polypeptides, including the amino sequence in its SNP variants (“polypeptide,” “peptide,” and “protein” are used interchangeably herein). Related polypeptides include allelic variants (e.g., SNP variants); splicing variants; fragments; derivatives; substitution, deletion, and insertion variants; fusion polypeptides; and interspecies homologs, which preferably retain hOX40L activity and / or are sufficient to produce an anti-hOX40L immune response. Soluble forms of hOX40L sufficient to produce an anti-hOX40L immune response are also covered. As those skilled in the art will recognize, the anti-hOX40L antibodies of the present invention can bind to hOX40L polypeptides, polypeptide fragments, antigens, and / or epitopes, since an epitope is part of a larger antigen, a larger antigen is part of a larger polypeptide fragment, and a larger polypeptide fragment is part of a larger polypeptide hOX40L, which can exist in trimer (natural) or monomer (denatured) form.

[0527] The term "Kabat number" and similar terms are recognized in the art and refer to a system of numbering amino acid residues that are more variable (i.e., hypervariable) than other amino acid residues in the heavy chain variable region of the antibody or its antigen-binding moiety (Kabat et al. (1971) Ann. NY Acad. Sci. 190: 382-391 and Kabat et al. (1991) Sequences of Proteins of Immunological Interest, 5th ed., USDapartment of Health and Human Services, NIH Publication No. 91-3242). For the heavy chain variable region, the hypervariable region typically ranges from amino acid position 31 to 35 for CDR1, from amino acid position 50 to 65 for CDR2, and from amino acid position 95 to 102 for CDR3.

[0528] The term "monoclonal antibody" refers to an antibody obtained from a group of homologous or substantially homologous antibodies, and each monoclonal antibody typically recognizes a single epitope on an antigen. In a preferred embodiment, "monoclonal antibody" as used herein is an antibody produced by a single hybridoma or other cell, wherein the antibody specifically binds only to the hOX40L epitope, as determined, for example, by an ELISA or other antigen-binding or competitive binding assay known in the art or provided herein. The term "monoclonal" is not limited to any particular method of preparing the antibody. For example, the monoclonal antibody of the present invention can be prepared by the hybridoma method described, such as in Kohler et al.; Nature, 256:495 (1975), or isolated, for example, from a phage library using techniques as described herein. Other methods for preparing clonal cell lines and the monoclonal antibodies expressed therefrom are well known in the art (see, for example, Chapter 11 of Short Protocols in Molecular Biology, (2002) 5th edition, eds. Ausubel et al., John Wiley and Sons, New York). Other exemplary methods for producing other monoclonal antibodies are provided in the embodiments herein.

[0538] In another implementation, the presence of biomarkers predicting transplant rejection or GvHD (e.g., acute GvHD) is monitored periodically post-transplant, and the anti-OX40L antibody of the present invention is administered once the biomarker levels determine that the patient is at risk of developing transplant rejection or GvHD (e.g., acute GvHD). This strategy avoids unnecessary drug administration and unnecessary immunosuppression. Examples of biomarkers that can be used as predictive biomarkers for acute GvHD include those identified by Levine et al., “A prognostic score for acute graft-versus-host disease based on biomarkers: a multicentre study,” Lancet Haematol 2015;2:e21-29.

An epitope may or may not be a three-dimensional surface feature of the antigen. A localized region on the surface of an hOX40L antigen that can elicit an immune response is an hOX40L epitope. An epitope may or may not be a three-dimensional surface feature of the antigen.

[0540] The terms "hOX40L-mediated disease" and "hOX40L-mediated symptom" are used interchangeably and refer to any disease or symptom that is wholly or partially caused by or is a result of hOX40L. In some embodiments, hOX40L is aberrantly (highly) expressed on the cell surface. In some embodiments, hOX40L may be aberrantly upregulated in specific cell types. In other embodiments, binding of hOX40L to its ligand causes normal, aberrant, or excessive cell signaling. In some embodiments, the hOX40L ligand is, for example, OX40 expressed on the cell surface, such as the surface of colonic epithelial cells. In some embodiments, the hOX40L-mediated disease is inflammatory bowel disease (IBD), such as Crohn's disease (CD) or ulcerative colitis (UC). In other embodiments, the hOX40L-mediated disease is graft-versus-host disease (GVHD). In other embodiments, hOX40L-mediated diseases are selected from pyoderma gangrene, giant cell arteritis, Schnitzler syndrome, non-infectious scleritis, and uveitis (non-infectious / autoimmune and / or systemic). In other embodiments, hOX40L-mediated diseases or conditions are selected from autoimmune diseases or conditions, systemic inflammatory diseases or conditions, or transplant rejection; for example, inflammatory bowel disease (IBD), Crohn's disease, rheumatoid arthritis, transplant rejection, allogeneic transplant rejection, graft-versus-host disease (GvHD), ulcerative colitis, systemic lupus erythematosus (SLE), diabetes, uveitis, ankylosing spondylitis, contact hypersensitivity, multiple sclerosis, and atherosclerosis, especially GvHD.

In a specific embodiment, the hOX40L receptor is Hox40. In some embodiments, the hOX40L receptor is expressed on the cell surface, such as the surface of colonic epithelial cells; or on graft or transplanted tissue; or on host tissue.

[0542] As used herein, the terms "subject" and "patient" are used interchangeably. As used herein, a subject is preferably a mammal such as a non-primate (e.g., cattle, pigs, horses, cats, dogs, rats, etc.) or a primate (e.g., monkeys and humans), most preferably a human. In one embodiment, the subject is a mammal suffering from an hOX40L-mediated disease, preferably a human. In another embodiment, the subject is a mammal at risk of developing an hOX40L-mediated disease, preferably a human.

[0543] As used in this article, “substantially all” means at least about 60%, at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 95%, at least about 98%, at least about 99%, or about 100%.

[0544] As used herein, “substantially free of surfactant” refers to an antibody formulation that specifically binds to the hOX40L antigen and contains less than 0.0005%, less than 0.0003%, or less than 0.0001% of surfactant and / or less than 0.0005%, less than 0.0003%, or less than 0.0001% of surfactant.

[0545] As used herein, “substantially salt-free” refers to an antibody formulation that specifically binds to the hOX40L antigen and contains less than 0.0005%, less than 0.0003%, or less than 0.0001% of inorganic salts.

[0546] As used herein, the term "surfactant" refers to an amphoteric organic substance; that is, it consists of groups with opposite solubility tendencies, typically oil-soluble hydrocarbon chains and water-soluble ionic groups. Surfactants can be classified into anionic, cationic, and nonionic surfactants based on the charge of their active moieties. Surfactants are commonly used as wetting agents, emulsifiers, solubilizers, and dispersants in the preparation of various pharmaceutical compositions and biomaterials.

[0547] As used herein, the term "tag" refers to any type of portion attached to, for example, a polypeptide and / or a polynucleotide encoding hOX40L or an hOX40L antibody or its antigen-binding fragment. For example, a polynucleotide encoding hOX40L, an hOX40L antibody, or its antigen-binding fragment may contain one or more additional tag-encoding nucleotide sequences encoding, for example, a detectable portion or a portion that facilitates affinity purification. During translation, the tag and antibody may be in the form of a fusion protein. The terms "detectable" or "detectable" with respect to a tag refer to any tag that is visible or in which the presence of the tag can be further determined and / or measured (e.g., by quantification). A non-limiting example of a detectable tag is a fluorescent tag.

[0548] As used herein, the term "therapeutic agent" refers to any agent that can be used to treat, manage, or improve hOX40L-mediated diseases and / or associated symptoms. In some embodiments, the term "therapeutic agent" refers to the antibody of the present invention. In some other embodiments, the term "therapeutic agent" refers to an agent other than the antibody of the present invention. Preferably, the therapeutic agent is an agent known for, or has been or is currently used for, the treatment, management, or improvement of one or more symptoms of hOX40L-mediated diseases or associated symptoms. In a specific embodiment, the prophylactic agent is a fully human anti-hOX40L antibody, such as a fully human anti-hOX40L monoclonal antibody.

[0549] Combinations of therapies (e.g., the use of preventative or therapeutic agents) are more effective than the additive effect of any two or more single therapies. For example, the synergistic effect of a combination of preventative and / or therapeutic agents allows for the use of one or more agents at lower doses and / or less frequent administration to subjects with hOX40L-mediated disease. The ability to utilize lower doses of preventative or therapeutic therapies and / or less frequent administration of the therapy reduces the toxicity associated with administering the therapy to subjects without reducing the efficacy of the therapy in the prevention, management, treatment, or improvement of hOX40L-mediated disease. Furthermore, synergistic effects can lead to enhanced efficacy of the therapy in the prevention, management, treatment, or improvement of hOX40L-mediated disease. Finally, the synergistic effect of combinations of therapies (e.g., preventative or therapeutic agents) can avoid or reduce adverse or harmful side effects associated with the use of any single therapy.

[0550] In one embodiment, the combination comprises the anti-OX40L antibody of the present invention and another therapeutic agent, said other therapeutic agent being independently selected from rapamycin (sirolimus), tacrolimus, cyclosporine, corticosteroids (e.g., methylprednisolone), methotrexate, mycophenolate mofetil, anti-CD28 antibody, anti-IL12 / IL-23 antibody (e.g., uterotumab), anti-CD20 antibody (e.g., rituximab), anti-CD30 antibody (e.g., butuximab), CTLA4-Fc molecule (e.g., abatacept), CCR5 receptor antagonist (e.g., malaviro), anti-CD40L antibody, anti-V LA4 antibodies (e.g., nastatin), anti-LFA1 antibodies, fludarabine, anti-CD52 antibodies (e.g., alenzab), anti-CD45 antibodies, cyclophosphamide, anti-thymocyte globulin, anti-complement C5 antibodies (e.g., eculizumab), anti-a4b7 integrin antibodies (e.g., vedolizumab), anti-IL6 antibodies (e.g., tocilizumab), anti-IL2R antibodies (e.g., baliximab), anti-CD25 antibodies (e.g., daliximab), anti-TNFa / TNFa-Fc molecules (e.g., etanercept, adalimumab, infliximab, golimumab, or sertozumab), and vorinostat. In another embodiment, the combination comprises the anti-OX40L antibody of the present invention and another therapeutic agent independently selected from rapamycin (sirolimus), tacrolimus, cyclosporine, corticosteroids (e.g., methylprednisolone), methotrexate, mycophenolate mofetil, anti-CD28 antibody, CTLA4-Fc molecule (e.g., abatacept), anti-CD40L antibody, anti-LFA1 antibody, anti-CD52 antibody (e.g., alemtuzumab), cyclophosphamide, and anti-thymocyte globulin.

[0551] As used herein, the term "therapy" means any regimen, method, and / or agent that can be used for the prevention, management, treatment, and / or improvement of hOX40L-mediated diseases (e.g., IBD or GVHD). In some embodiments, the term "therapy" means a biological therapy, supportive therapy, and / or other therapy that is useful in the prevention, management, treatment, and / or improvement of hOX40L-mediated diseases as known to those skilled in the art as medical personnel.

[0552] As used herein, the term "treatment" refers to a reduction or improvement in the progression, severity, and / or duration of hOX40L-mediated disease (e.g., IBD or GVHD) caused by the administration of one or more therapies (including, but not limited to, the administration of one or more prophylactic or therapeutic agents, such as the antibodies of the present invention). In specific embodiments, such terms refer to a reduction or inhibition of hOX40L binding to OX40, a reduction or inhibition of CCL20 production or secretion from cells expressing hOX40 or hOX40L, a reduction or inhibition of IL-8 production or secretion from cells expressing hOX40 or hOX40L, a reduction or inhibition of RANTES production or secretion from cells expressing hOX40 or hOX40L, and / or inhibition or relief of one or more symptoms associated with hOX40L-mediated diseases such as IBD or GVHD. In specific embodiments, such terms refer to the reduction or inhibition of hOX40L binding to OX40, the reduction or inhibition of INF-γ production or secretion from cells expressing hOX40 or hOX40L, the reduction or inhibition of TNF-α production or secretion from cells expressing hOX40 or hOX40L, the reduction or inhibition of IL-2 production or secretion from cells expressing hOX40 or hOX40L, and / or the inhibition or mitigation of one or more symptoms associated with hOX40L-mediated diseases such as IBD or GVHD (especially GvHD). In one instance, the cell is a human cell. In specific embodiments, the prophylactic agent is a fully human anti-hOX40L antibody, such as a fully human anti-hOX40L monoclonal antibody.

[0553] The term "variable region" or "variable domain" refers to a portion of the OX40L and heavy chain, typically about 120 to 130 amino acids from the N-terminus of the heavy chain and about 100 to 110 amino acids from the light chain, which are widely different in sequence among antibodies and are responsible for the binding and specificity of each specific antibody to its specific antigen. Sequence variability is concentrated in those regions called complementarity-determining regions (CDRs), while more highly conserved regions within the variable domain are called backbone regions (FRs). The CDRs of the OX40L and heavy chain are primarily responsible for antibody-antigen interactions. The amino acid positions used herein are numbered according to the EU index, as described in Kabat et al. (1991), Sequences of proteins of immunological interest (USD Department of Health and Human Services, Washington, DC), 5th edition ("Kabat et al."). In a preferred embodiment, the variable region is a human variable region.

[0554] Antibody

[0555] The antibodies of the present invention include, but are not limited to, synthetic antibodies, monoclonal antibodies, recombinant antibodies, multispecific antibodies (including bispecific antibodies), human antibodies, humanized antibodies, chimeric antibodies, intracellular antibodies, single-chain Fvs (scFv) (e.g., including monospecific, bispecific, etc.), camelified antibodies, Fab fragments, F(ab′) fragments, disulfide-linked Fvs (sdFv), anti-idiotype (anti-Id) antibodies, and epitope-binding fragments of any of the above.

[0556] Specifically, the antibodies provided herein comprise immunoglobulin molecules and the immunoactive portions of immunoglobulin molecules, i.e., molecules containing antigen-binding sites that specifically bind to the hOX40L antigen. The immunoglobulin molecules provided herein can be any type (e.g., IgG, IgE, IgM, IgD, IgA, and IgY), class (e.g., IgG1, IgG2, IgG3, IgG4, IgA1, and IgA2), or subclass of immunoglobulin molecules. In one specific embodiment, the antibody provided herein is an IgG antibody, preferably IgG1 or IgG4. In some embodiments, the antibody of the present invention contains a human γ4 constant region. In another embodiment, the heavy chain constant region does not bind to the Fc-γ receptor and, for example, contains the Leu235Glu mutation. In another embodiment, the heavy chain constant region contains the Ser228Pro mutation to increase stability. In yet another embodiment, the heavy chain constant region is IgG4-PE.

[0557] Antibody variants and derivatives include antibody fragments that retain the ability to specifically bind to epitopes. Preferred fragments include Fab fragments; Fab′ (antibody fragments containing a single anti-binding domain comprising Fab and a heavy chain appendage via a hinge region); F(ab′)2 (two Fab′ molecules linked by interchain disulfide bonds within the heavy chain hinge region; Fab′ molecules may target the same or different epitopes); bispecific Fab (Fab molecules having two antigen-binding domains, each of which can target a different epitope); single-chain Fab chains containing variable regions, also known as sFv; disulfide-linked Fv or dsFv; camel-derived VH (antibodies where some amino acids at the VH interface are amino acids found in the heavy chain of naturally occurring camel antibodies). The invention includes: a single heavy chain variable antigen-binding determinant region (SFR); a bispecific sFv (sFv or dsFv molecule having two antigen-binding domains, each of which can target different epitopes); a double-chain antibody (a dimerized sFv formed when the VH domain of a first sFv assembles with the VL domain of a second sFv and the VL domain of the first sFv assembles with the VH domain of the second sFv; the two antigen-binding domains of the double-chain antibody can target the same or different epitopes); and a triple-chain antibody (a trimerized sFv formed in a manner similar to that of a double-chain antibody, but wherein three antigen-binding domains are generated in a single complex; the three antigen-binding domains can target the same or different epitopes). Antibody derivatives also include one or more CDR sequences at the antibody binding site. When two or more CDR sequences are present, the CDR sequences can be linked together on the backbone. In some embodiments, antibodies used with the invention comprise a single-chain Fv (“scFv”). scFv is an antibody fragment containing the VH and VL domains of the antibody, wherein these domains are present in a single polypeptide chain. Typically, scFv peptides also contain peptide linkers located between the VH and VL domains, enabling scFv to form the desired structure for antigen binding. For a review of scFv, see Pluckthun, The Pharmacology of Monoclonal Antibodies, Vol. 113, eds. Rosenburg and Moore, Springer-Verlag, New York, pp. 269–315 (1994).

[0558] The antibodies of this invention can be derived from any animal source, including birds and mammals (e.g., humans, rodents, donkeys, sheep, rabbits, goats, guinea pigs, camels, horses, or chickens). In some embodiments, the antibodies of this invention are human or humanized monoclonal antibodies. As used herein, "human" antibodies include antibodies having the amino acid sequence of human immunoglobulins and include antibodies isolated from a human immunoglobulin library or from mice expressing antibodies derived from human genes.

[0559] In a preferred embodiment, the antibody of the present invention is a fully human antibody, such as a fully human antibody that specifically binds to the hOX40L polypeptide, the hOX40L polypeptide fragment, or the hOX40L epitope. Such fully human antibodies will be advantageous over whole mouse (or other fully or partially non-human species antibodies), humanized antibodies, or chimeric antibodies in minimizing harmful or unwanted side effects, such as immune responses to non-fully human antibodies (e.g., anti-hOX40L antibodies derived from other species), when administered to a subject.

[0560] The antibodies of this invention can be monospecific, bispecific, trispecific, or even more multispecific. Multispecific antibodies can be specific to different epitopes of the hOX40L peptide or to both the hOX40L peptide and heterologous epitopes, such as heterologous peptides or solid support materials. In a preferred embodiment, the antibody provided herein is monospecific to a given epitope of the hOX40L peptide and does not specifically bind to other epitopes.

[0561] This article also provides B cells (e.g., immortalized B cells) or hybridomas that produce the anti-hOX40L antibody or fragment described herein.

[0562] In some embodiments, this document provides an isolated antibody that specifically binds to the hOX40L epitope, wherein the binding of the antibody to the hOX40L epitope is competitively blocked by the antibody or fragment of the present invention (e.g., in a dose-dependent manner). The antibody may or may not be a fully human antibody. In a preferred embodiment, the antibody is a fully human monoclonal anti-hOX40L antibody, and even more preferably a fully human, monoclonal, antagonistic anti-hOX40L antibody. Exemplary competitive blocking assays are provided in the embodiments herein.

[0563] In some embodiments, the antibody or fragment of the present invention competitively (e.g., in a dose-dependent manner) binds to hOX40L expressed on the cell surface against the OX40 receptor (or its fusion protein). In other embodiments, the antibody or fragment of the present invention competitively (e.g., in a dose-dependent manner) binds to soluble hOX40L against the OX40 receptor (or its fusion protein). Exemplary competitive binding assays available are provided in the embodiments herein. In one embodiment, the antibody or fragment partially or completely inhibits the binding of hOX40 to OX40L expressed on the cell surface, such as hOX40L. In another embodiment, the antibody partially or completely inhibits the binding of hOX40 to soluble hOX40L. In some embodiments, the antibody or fragment partially or completely inhibits the secretion of CCL20, IL-8 and / or RANTES or INF-γ, TNF-α or IL-2, especially INF-γ, from cells having OX40 expressed on their cell surface. In some embodiments, the cells expressing OX40 are colonic epithelial cells.

[0564] Preferably, the antibody of the present invention is a fully human, monoclonal antibody, such as a fully human, monoclonal antagonistic antibody that specifically binds to hOX40L.

[0565] In some embodiments, the antibody or fragment provided herein binds to an hOX40L epitope, which is a three-dimensional surface feature of an hOX40L polypeptide (in the form of a trimer of the hOX40L polypeptide). The hOX40L polypeptide region contributing to the epitope may be a continuous amino acid of the polypeptide, or the epitope may originate together from two or more discontinuous regions of the polypeptide. The hOX40L epitope may be present in (a) a trimer of hOX40L (“trimeric hOX40L epitope”), (b) a monomer of hOX40L (“monomer hOX40L epitope”), (c) a trimer and monomer of hOX40L, (d) a trimer of hOX40L but not a monomer, or (e) a monomer of hOX40L but not a trimer.

[0566] For example, in some embodiments, the epitope exists or is available for binding only in a trimer (natural) form, but not in a monomer (denatured) form or for binding to an anti-hOX40L antibody. In other embodiments, the hOX40L epitope is a linear characteristic of the hOX40L polypeptide (e.g., in a trimer or monomeric form). The antibodies provided herein can specifically bind to (a) the hOX40L monomeric (denatured) epitope, (b) the hOX40L trimeric epitope, (c) the hOX40L monomeric but not trimeric epitope, (d) the hOX40L trimeric but not monomeric epitope, or (e) both the hOX40L monomeric and trimeric forms. In a preferred embodiment, the antibodies provided herein specifically bind to the hOX40L trimeric epitope, but not specifically bind to the hOX40L monomeric epitope.

[0567] This invention also provides antibodies that specifically bind to the hOX40L epitope, comprising derivatives of the VH domain, VH CDR, VL domain, and VL CDR of the hOX40L antigen as described herein. This invention also provides antibodies comprising the antibody derivatives disclosed in the examples, wherein said antibodies specifically bind to the hOX40L epitope. Standard techniques known to those skilled in the art can be used to introduce mutations into the nucleotide sequence encoding the molecule of this invention, including, for example, site-directed mutagenesis producing amino acid substitutions and PCR-mediated mutagenesis. Preferably, the derivative comprises fewer than 25 amino acid substitutions, fewer than 20 amino acid substitutions, fewer than 15 amino acid substitutions, fewer than 10 amino acid substitutions, fewer than 5 amino acid substitutions, fewer than 4 amino acid substitutions, fewer than 3 amino acid substitutions, or fewer than 2 amino acid substitutions relative to the original molecule. In another embodiment, the derivative has conserved amino acid substitutions. In a preferred embodiment, the derivative has conserved amino acid substitutions produced at one or more predicted non-essential amino acid residues. Optionally, mutations may be introduced randomly along the entire or partial coding sequence, for example, by saturation mutagenesis, and the resulting mutants may be screened for biological activity to identify mutants that retain activity. After mutagenesis, the encoded protein can be expressed and its activity can be measured.

[0568] In another embodiment, the antibody that specifically binds to the hOX40L epitope comprises a variable domain amino acid sequence that is at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or at least 99% identical to the variable domain amino acid sequence in the sequence listing.

[0569] In specific embodiments, the antibody is a fully human anti-human antibody, such as a fully human monoclonal antibody. Fully human antibodies can be generated by any method known in the art. Exemplary methods include immunizing a transgenic animal (e.g., a mouse) with an hOX40L antigen (any hOX40L polypeptide capable of evoking an immune response and optionally conjugated to a vector) that is capable of generating a human antibody library in the absence of endogenous immunoglobulin production; see, for example, Jakobovits et al., (1993) Proc. Natl. Acad. Sci., 90: 2551; Jakobovits et al., (1993) Nature, 362: 255-258 (1993); Bruggermann et al., (1993) Year in Immunol., 7: 33. Other methods for generating fully human anti-hOX40L antibodies can be found in the embodiments provided herein.

[0570] Optionally, fully human antibodies can be generated by screening phage display antibody libraries in vitro; see, for example, Hoogenboom et al., J. Mol. Biol., 227:381 (1991); Marks et al., J. Mol. Biol., 222:581 (1991), which are incorporated herein by reference. Various antibody-containing phage display libraries have been described and are readily prepared by those skilled in the art. Libraries can contain a wide variety of human antibody sequences that can be screened for suitable targets, such as human Fab, Fv, and scFv fragments.

[0571] The antibodies and fragments of the present invention include chemically modified antibodies and fragments, i.e., modified by covalent linking of any type of molecule to the antibody. For example, but not in a limiting manner, antibody derivatives include antibodies that have been chemically modified (e.g., by known glycosylation, acetylation, polyethylene glycolation, phosphorylation, amidation, derivatization with known protecting / capping groups, proteolytic cleavage, or linkage to cellular ligands or other proteins. Any of these chemical modifications can be performed using known techniques, including but not limited to specific chemical cleavage, acetylation, formulation, and metabolic synthesis of tunicamycin. Additionally, the antibodies may contain one or more non-classical amino acids.

[0572] The present invention also provides antibodies that specifically bind to the hOX40L antigen, comprising a backbone region (e.g., human or non-human backbone) known to those skilled in the art. The backbone region may be, for example, a naturally occurring or shared backbone region.

See typically U.S. Patents 5,605,793, 5,811,238, 5,830,721, 5,834,252, and 5,837,458; Patten et al., 1997, Curr. Opinion Biotechnol. 8: 724-33; Harayama, 1998, Trends Biotechnol. 16(2): 76-82; Hansson et al., 1999, J. Mol. Biol. 287: 265-76; and Lorenzo and Blasco, 1998, Biotechniques 24(2): 308-313 (each of these patents and publications is incorporated herein by reference in its entirety).

[0600] Formulations that can be administered in vivo can be sterile. This can be easily achieved through filtration, for example, using a sterile filtration membrane.

[0601] Sustained-release formulations can also be prepared. Suitable examples of sustained-release formulations include semi-permeable matrices of solid hydrophobic polymers containing antagonists, said matrices being in the form of molded articles (e.g., films or microcapsules). Examples of sustained-release matrices include polyesters, hydrogels (e.g., poly(2-hydroxy-methacrylate) or poly(vinyl alcohol)), polylactide (US Patent No. 3,773,919), copolymers of L-glutamic acid and L-glutamic acid-ethyl ester, non-degradable ethylene-vinyl acetate, and degradable lactic acid-glycolic acid copolymers such as LUPRON DEPOT. TM (Injectable microspheres composed of lactic-glycolic acid copolymers and leuprolide acetate) and poly-D-(-)-3-hydroxybutyric acid. While polymers such as ethylene-vinyl acetate and lactic-glycolic acid allow molecules to be released for more than 100 days, some hydrogels release proteins for a shorter period. When encapsulated antibodies are held in vivo for extended periods, they can denature or aggregate due to exposure to moisture at 37°C, leading to loss of biological activity and possible changes in immunogenicity. Stabilization strategies can be designed based on the mechanisms involved. For example, if aggregation is found to occur via intermolecular SS bonds formed through thio-disulfide exchange, stabilization can be achieved by modifying thiol residues, lyophilizing from acidic solutions, controlling moisture content, using appropriate additives, and developing specific polymer matrix compositions.

[0602] The pharmaceutical compositions provided herein contain a therapeutically effective amount of one or more antibodies of the present invention in a pharmaceutically acceptable carrier, and optionally one or more additional prophylactic or therapeutic agents. Such pharmaceutical compositions are useful in the prevention, treatment, management, or improvement of hOX40L-mediated diseases, such as inflammatory bowel disease, transplant rejection, GvHD, or one or more of their symptoms.

[0603] Drug carriers suitable for administering the compounds provided herein include any such carriers known to those skilled in the art as being suitable for a particular mode of administration.

[0604] In addition, the antibody of the present invention can be formulated as the sole pharmaceutical active ingredient in a composition or can be combined with other active ingredients (such as one or more other preventive or therapeutic agents).

[0605] The composition may contain one or more antibodies of the present invention. In one embodiment, the antibody is formulated into a suitable pharmaceutical preparation for oral administration, such as a solution, suspension, tablet, dispersible tablet, pill, capsule, powder, sustained-release formulation or elixir, or formulated into a sterile solution or suspension for parenteral administration, as well as transdermal patch formulations and dry powder inhalers. In one embodiment, the above-described antibody is formulated into a pharmaceutical composition using techniques and procedures well known in the art (see, for example, Ansel (1985) Introduction to Pharmaceutical Dosage Forms, 4th edition, page 126).

[0606] In the composition, an effective concentration of one or more antibodies or their derivatives is mixed with a suitable drug carrier. The concentration of the compound in the composition is effective for delivering an amount that can treat, prevent, or improve hOX40L-mediated diseases or their symptoms after administration.

[0607] In one embodiment, the composition is formulated for single-dose administration. To formulate the composition, a certain weight fraction of the compound is dissolved, suspended, dispersed, or otherwise mixed with a selected carrier at an effective concentration to relieve, prevent, or improve one or more symptoms.

[0608] The antibodies of the present invention are contained in a pharmaceutically acceptable carrier in an effective amount sufficient to produce a therapeutically useful effect without adverse side effects on the treated patient. Therapeuticly effective concentrations can be empirically determined by testing the compounds in vitro and in vivo systems using conventional methods, from which the dosage for humans can be deduced.

[0609] The concentration of antibodies in a pharmaceutical composition will depend on factors such as the physicochemical characteristics of the antibodies, the dosing regimen and the amount administered, as well as other factors known to those skilled in the art.

[0610] In one embodiment, the therapeutically effective dose produces an antibody serum concentration of about 0.1 ng / ml to about 50-100 μg / ml. In another embodiment, the pharmaceutical composition provides a dose of about 0.001 mg to about 2000 mg antibody / kg body weight per day. The pharmaceutical dosage units can be prepared to provide each dosage unit of about 0.01 mg, 0.1 mg, or 1 mg to about 500 mg, 1000 mg, or 2000 mg, and in one embodiment, a combination of about 10 mg to about 500 mg antibody and / or other optional essential components.

[0611] Antibodies can be administered in a single dose or divided into multiple smaller doses administered at different time intervals. It should be understood that the precise dosage and duration of treatment are functions of the disease being treated and can be determined empirically using known experimental protocols or inferred from in vivo or in vitro test data. It should be noted that concentration and dosage values ​​may also vary depending on the severity of the symptoms to be alleviated. It should also be understood that for any given subject, the specific dosage regimen may be adjusted over time according to individual needs and the professional judgment of the person administering or supervising the composition, and the concentration ranges presented herein are merely illustrative and not intended to limit the scope or practice of the claimed compositions.

[0612] After antibodies are mixed or added, the resulting mixture can be a solution, suspension, emulsion, etc. The form of the resulting mixture depends on many factors, including the intended administration method and the solubility of the compound in the chosen carrier or medium. The effective concentration is sufficient to improve the symptoms of the treated disease, condition, or symptom and can be determined empirically.

[0613] Pharmaceutical compositions are provided in unit dose forms, such as tablets, capsules, pills, powders, granules, sterile parenteral solutions or suspensions, and oral solutions or suspensions, as well as oil-water emulsions containing an appropriate amount of the compound or a pharmaceutically acceptable derivative thereof, for administration to humans and animals. In one embodiment, the antibody is formulated and administered in unit dose or multiple dose forms. As used herein, a unit dose form refers to a physically discrete unit suitable for human and animal subjects and individually packaged as known in the art. Each unit dose contains a predetermined amount of antibody sufficient to produce the desired therapeutic effect when combined with the desired drug carrier, mediator, or diluent. Examples of unit dose forms include ampoules and syringes, and individually packaged tablets or capsules. Unit dose forms can be administered in multiple doses or multiple times. Multiple dose forms are multiple identical unit dose forms packaged in a single container and administered in separate unit dose forms. Examples of multiple dose forms include vials, bottles, or pints or gallon bottles of tablets or capsules. Thus, a multiple dose form is multiple unit doses not separated on the packaging.

[0614] In a preferred embodiment, one or more anti-hOX40L antibodies of the present invention are in the form of a liquid pharmaceutical formulation. Pharmaceutically applicable liquid compositions can be prepared, for example, by dissolving, dispersing, or otherwise mixing the above-defined active compound and optional pharmaceutical excipients in a carrier such as water, saline, dextran aqueous solution, glycerol, ethylene glycol, ethanol, etc., to form a solution or suspension. If desired, the pharmaceutical composition to be applied may also contain trace amounts of non-toxic excipients such as wetting agents, emulsifiers, solubilizers, pH buffers, etc., for example, acetates, sodium citrate, cyclodextrin derivatives, sorbitol monolaurate, sodium triethanolamine acetate, triethanolamine oleate, and other such reagents.

[0615] The actual methods for preparing such dosage forms are known or will be obvious to those skilled in the art; see, for example, Remington's Pharmaceutical Sciences (1990), Mack Publishing Co., Easton, Pa.

[0616] Dosage forms or compositions containing 0.005% to 100% antibody, with the remainder consisting of a non-toxic carrier, can be prepared. Methods for preparing these compositions are known to those skilled in the art.

[0617] Oral medications are available in solid, gel, or liquid dosage forms. Solid dosage forms include tablets, capsules, granules, and bulk powders. Types of oral tablets include compressed, chewable lozenges, and tablets, which may be enteric-coated, sugar-coated, or film-coated. Capsules may be hard or soft gelatin capsules, while granules and powders may be provided in non-effervescent or effervescent forms in combination with other ingredients known to those skilled in the art.

[0618] In some embodiments, the formulation is a solid dosage form. In some embodiments, the formulation is a capsule or tablet.

[0619] The antibodies of the present invention can be provided in compositions that protect them from the acidic environment of the stomach. For example, the composition is formulated in an enteric coating that maintains its integrity in the stomach and releases the active compound in the intestine. The composition can also be formulated in combination with antacids or other such ingredients.

[0620] When the dosage unit is in capsule form, it may contain a liquid carrier, such as fatty oil, in addition to the materials of the types mentioned above. Furthermore, the dosage unit form may contain various other materials that alter the physical form of the dosage unit, such as sugars and other enteric coatings. The compound may also be applied as a component of elixirs, suspensions, syrups, rice paper capsules, sprays, chewing gum, etc. Syrups may contain sucrose as a sweetener, as well as certain preservatives, dyes and colorants, and flavorings, in addition to the active compound.

[0621] The antibody may also be mixed with other active materials that do not impair the desired effect or with other materials that complement the desired effect, such as antacids, H2 blockers, and diuretics. The active ingredient is an antibody or a pharmaceutically acceptable derivative thereof as described herein. Higher concentrations of the active ingredient, up to about 98% by weight, may be included.

[0622] In all embodiments, the tablet and capsule formulations may be coated, as is known to those skilled in the art, to alter or maintain the solubility of the active ingredient. Thus, for example, they may be coated with conventional enterically digestible coatings such as phenyl salicylate, waxes, and cellulose acetate phthalate.

[0623] In a preferred embodiment, the formulation is a liquid dosage form. Liquid dosage forms include aqueous solutions, emulsions, suspensions, solutions, and / or suspensions rehydrated from non-effervescent granules and effervescent formulations rehydrated from effervescent granules. Aqueous solutions include, for example, elixirs and syrups. Emulsions are oil-in-water or water-in-oil emulsions.

[0627] For solid dosage forms, solutions or suspensions in, for example, propylene carbonate, vegetable oils, or triglycerides, are, in one embodiment, encapsulated in gelatin capsules. Such solutions, their preparation, and encapsulation are disclosed in U.S. Patent Nos. 4,328,245, 4,409,239, and 4,410,545. For liquid dosage forms, solutions, such as those in polyethylene glycol, may be diluted with a sufficient amount of a pharmaceutically acceptable liquid carrier, such as water, for easy measurement and administration.

[0628] Alternatively, liquid or semi-solid oral formulations can be prepared by dissolving or dispersing the active compound or salt in vegetable oils, glycols, triglycerides, propylene glycol esters (e.g., propylene carbonate), and other such carriers, and encapsulating these solutions or suspensions in hard or soft gelatin capsule shells. Other useful formulations include those proposed in U.S. Patents RE28,819 and 4,358,603. In short, such formulations include, but are not limited to, those containing the compounds provided herein, dialkylated mono- or polyalkylene glycols (including, but not limited to, 1,2-dimethoxymethane, diethylene glycol dimethyl ether, triethylene glycol dimethyl ether, tetraethylene glycol dimethyl ether, polyethylene glycol-350-dimethyl ether, polyethylene glycol-550-dimethyl ether, polyethylene glycol-750-dimethyl ether), and one or more antioxidants (such as butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), propyl gallate, vitamin E, hydroquinone, hydroxycoumarin, ethanolamine, lecithin, cephalin, ascorbic acid, malic acid, sorbitol, phosphoric acid, thiodipropionic acid and its esters, and dithiocarbamates), wherein 350, 550, and 750 refer to the approximate average molecular weight of polyethylene glycol.

[0630] In one embodiment, this document also considers parenteral administration characterized by subcutaneous, intramuscular, or intravenous injection. The injection can be prepared in conventional forms, such as as a liquid solution or suspension, a solid form of a solution or suspension suitable for use in a liquid prior to injection, or as an emulsion. The injection, solution, and emulsion also contain one or more excipients. Suitable excipients are, for example, water, saline, dextran, glycerol, or ethanol. Additionally, if desired, the pharmaceutical composition to be administered may also contain trace amounts of non-toxic excipients such as wetting agents, emulsifiers, pH buffers, stabilizers, solubility enhancers, and other such agents, such as sodium acetate, sorbitol monolaurate, triethanolamine oleate, and cyclodextrin.

[0631] This document also considers implantation of sustained-release or continuous-release systems that maintain a constant dose level (see, for example, U.S. Patent No. 3,710,795). In short, the compounds described herein are dispersed in an internal solid matrix, such as polymethyl methacrylate, polybutyl methacrylate, plasticized or unplasticized polyvinyl chloride, plasticized nylon, plasticized polyethylene terephthalate, natural rubber, polyisoprene, polyisobutylene, polybutadiene, polyethylene, ethylene-vinyl acetate copolymer, silicone rubber, polydimethicone, silica-carbonate copolymer, hydrophilic polymers (such as hydrogels of acrylic acid and methacrylate), collagen, and an external polymeric membrane (e.g., polyethylene, polypropylene, ethylene / ...). Crosslinked polyvinyl alcohol (CVA) surrounded by propylene copolymers, ethylene / ethyl acrylate copolymers, and ethylene / vinyl acetate copolymers, and partially hydrolyzed crosslinked polyvinyl acetate, silicone rubber, polydimethylsiloxane, chloroprene rubber, chlorinated polyethylene, polyvinyl chloride, vinyl chloride and vinyl acetate, vinylidene chloride, copolymers of ethylene and propylene, ionomers of polyethylene terephthalate, butyl rubber, epichlorohydrin rubber, ethylene / vinyl alcohol copolymers, ethylene / vinyl acetate / vinyl alcohol terpolymers, and ethylene / vinyloxyethanol insoluble in body fluids. In a controlled release rate step, the antibody diffuses through an external polymer membrane. The amount of antibody contained in such parenteral compositions is highly dependent on their specific properties, the activity of the compound, and the needs of the subject.

[0632] Preparations intended for parenteral administration include readily injectable sterile solutions, sterile dried soluble products (such as lyophilized powders, including subcutaneous tablets) readily recombinable with solvents immediately before use, readily injectable sterile suspensions, sterile dried insoluble products readily recombinable with media immediately before use, and sterile emulsions. The solutions may be aqueous or non-aqueous.

[0633] If administered intravenously, suitable carriers include physiological saline or phosphate-buffered saline (PBS) and solutions and mixtures thereof containing thickeners and solubilizers such as glucose, polyethylene glycol, and polypropylene glycol.

[0634] Pharmaceutically acceptable carriers used in parenteral preparations include aqueous media, non-aqueous media, antibacterial agents, isotonic agents, buffers, antioxidants, local anesthetics, suspending and dispersing agents, emulsifiers, masking or chelating agents, and other pharmaceutically acceptable substances.

[0635] Examples of aqueous parenteral media include sodium chloride injection, Ringer's injection, isotonic dextran injection, sterile water injection, and dextran and lactated Ringer's injection. Non-aqueous parenteral media include non-volatile plant-derived oils, cottonseed oil, sesame oil, and peanut oil. Antimicrobial agents, including phenol or cresol, mercury, benzyl alcohol, chlorobutanol, methylparaben and propylparaben, thimerosal, benzalkonium chloride, and benzyl ethoxymonochloride, can be added to parenteral preparations packaged in multi-dose containers.

Drug carriers also include ethanol, polyethylene glycol, and polypropylene glycol for water-soluble media; and sodium hydroxide, hydrochloric acid, citric acid, or lactic acid for pH adjustment.

[0636] The concentration of the active pharmaceutical compound is adjusted so that the injection provides an effective amount to produce the desired pharmacological effect. As is known in the art, the precise dosage depends on the patient's or animal's age, weight, and condition.

[0637] Unit-dose parenteral preparations may be packaged in ampoules, vials, or syringes with needles. As is known and practiced in the art, all preparations intended for parenteral administration are sterile.

[0638] Illustratively, intravenous or arterial infusion of a sterile aqueous solution containing the active compound is an effective mode of administration. Another implementation is, if necessary, injection of a sterile aqueous or oil solution or suspension containing the active substance to produce the desired pharmacological effect.

[0639] Injectable formulations designed for both local and systemic application. In one embodiment, a therapeutically effective dose is formulated to contain an active compound at a concentration of at least about 0.1% w / w to about 90% w / w or higher, and in some embodiments, more than 1% w / w, for use on the treated tissue.

[0640] The antibody is suspended in a micronized or other suitable form. The form of the resulting mixture depends on many factors, including the intended administration method and the solubility of the compound in the chosen carrier or medium. An effective concentration is sufficient to improve the symptoms of the condition and can be determined empirically.

[0641] In other embodiments, the pharmaceutical preparation is a lyophilized powder that can be rehydrated into solutions, emulsions, and other mixtures for application. It can also be rehydrated and formulated into solids or gels.

[0642] Lyophilized powders are prepared by dissolving the antibodies or pharmaceutically acceptable derivatives thereof provided herein in a suitable solvent. In some embodiments, the lyophilized powder is sterile. The solvent may contain excipients or other pharmacological components of a powder or a reconstituted solution prepared from the powder to improve stability. Available excipients include, but are not limited to, dextran, sorbitol, fructose, corn syrup, xylitol, glycerol, glucose, sucrose, or other suitable reagents. The solvent may also contain a buffer, such as citrate, sodium or potassium phosphate, or other such buffers known to those skilled in the art, and in one embodiment, approximately neutral pH. Subsequent sterile filtration of the solution, followed by lyophilization under standard conditions known to those skilled in the art, provides the selected formulation. In one embodiment, the resulting solution is aliquoted into vials for lyophilization. Each vial will contain a single dose or multiple doses of the compound. The lyophilized powder may be stored under appropriate conditions, such as at about 4°C to room temperature.

[0643] This lyophilized powder is rehydrated with water for injection to provide a formulation for parenteral administration. For rehydration, the lyophilized powder is added to sterile water or other suitable carrier. The precise amount depends on the compound selected. This amount can be determined via [method / method / etc.].

[0644] As described for both topical and systemic application, prepare a topical mixture. The resulting mixture may be a solution, suspension, emulsion, etc., and may be formulated into creams, gels, ointments, lotions, solutions, elixirs, lotions, suspensions, tinctures, pastes, foams, aerosols, rinses, sprays, suppositories, bandages, skin patches, or any other formulation suitable for surface application.

[0645] The antibodies of the present invention can be formulated into aerosols for application, for example, by inhalation of a surface (see, for example, U.S. Patents 4,044,126, 4,414,209, and 4,364,923, which describe aerosols for delivering steroids useful for treating inflammatory diseases, particularly asthma). These formulations for administration to the respiratory tract, alone or in combination with an inert carrier such as lactose, can be in aerosol or solution form for nebulizers, or in fine powder form for inhalation. In such cases, the particles of the formulation will have a diameter of less than 50 micrometers in one embodiment and less than 10 micrometers in another embodiment.

[0646] The compounds can be formulated for topical or surface application, such as in gels, creams, and lotions for application to the skin and mucous membranes (e.g., the eyes) and for application to the eyes, or for application to the intracranial or spinal cord. Surface application is considered for transdermal delivery and also for application to the eyes or mucous membranes, or for inhalation therapy. Nasal solutions of the active compounds, alone or in combination with other pharmaceutically acceptable excipients, can also be administered.

[0647] These solutions, especially those intended for ophthalmic use, can be prepared as 0.01%–10% isotonic solutions with a pH of approximately 5–7 using appropriate salts.

[0648] This article also considers other routes of administration, such as transdermal patches, including iontophoresis and electrophoresis devices, and rectal administration.

[0649] Transdermal patches, including iontophoresis and electrophoresis devices, are well known to those skilled in the art. Such patches are disclosed, for example, in U.S. Patents 6,267,983, 6,261,595, 6,256,533, 6,167,301, 6,024,975, 6,010,715, 5,985,317, 5,983,134, 5,948,433, and 5,860,957.

[0650] For example, pharmaceutical dosage forms for rectal administration include systemic suppositories, capsules, and tablets. As used herein, a rectal suppository is a solid that is inserted into the rectum, melts or softens at body temperature, and releases one or more pharmacologically or therapeutically active ingredients. Pharmaceutically acceptable substances in rectal suppositories are a matrix or carrier and a melting point-enhancing agent. Examples of matrices include cocoa butter (cocoa soybean oil), glycerol-gelatin, carbon wax (polyethylene glycol), and suitable mixtures of fatty acid monoglycerides, diglycerides, and triglycerides. Combinations of various matrices can be used. Agents that enhance the melting point of suppositories include cetylene and waxes. Rectal suppositories can be prepared by compression or molding. In one embodiment, the weight of the rectal suppository is about 2 to 3 gm.

[0651] Tablets and capsules for rectal administration can be prepared using the same pharmaceutically acceptable substances and by the same methods as those used for oral administration.

[0652] The antibodies and other compositions described herein can also be formulated to target specific tissues, receptors, or other areas of the body of a subject to be treated. Many such targeting methods are well known to those skilled in the art. All such targeting methods for use in ready-to-use compositions are considered herein. For non-limiting examples of targeting methods, see, for example, U.S. Patent Nos. 6,316,652, 6,274,552, 6,271,359, 6,253,872, 6,139,865, 6,131,570, 6,120,751, 6,071,495, 6,060,082, 6,048,736, 6,039,975, 6,004,534, 5,985,307, 5,972,366, 5,900,252, 5,840,674, 5,759,542, and 5,709,874. In some embodiments, the anti-hOX40L antibody of the present invention is targeted (or otherwise administered) to the colon, for example, in a patient with IBD or at risk of developing IBD. In some embodiments, the anti-hOX40L antibody of the present invention is targeted (or otherwise administered) to the eye, for example, in a patient with uveitis or at risk of uveitis.

[0653] In one embodiment, liposomal suppositories, including tissue-targeting liposomes such as tumor-targeting liposomes, may also be suitable as pharmaceutically acceptable carriers. These can all be prepared according to methods known to those skilled in the art. For example, liposomal formulations are prepared as described in U.S. Patent No. 4,522,811. Briefly, liposomes such as multilayer vesicles (MLVs) can be formed by drying lecithin and cephalinositol serine (7:3 molar ratio) inside a flask. A solution of the compounds provided herein in phosphate-buffered saline (PBS) lacking divalent cations is added and the flask is shaken until the lipid membrane is dispersed. The resulting vesicles are washed to remove unencapsulated compounds, granulated by centrifugation, and then resuspended in PBS.

[0654] Administration and Dosage Methods

[0655] The present invention also provides compositions comprising one or more antibodies or fragments of the present invention for the prevention, management, treatment, and / or improvement of hOX40L-mediated diseases (or symptoms thereof). Discussions regarding antibodies, with necessary modifications, also apply to fragments of the present invention. In an alternative embodiment, the present invention also provides compositions comprising one or more antibodies or fragments of the present invention for the prevention, management, treatment, and / or improvement of OX40L-mediated diseases (or symptoms thereof) in subjects, wherein OX40L is non-human (e.g., dog, cat, horse, cow, sheep, or pig) and the subjects are dogs, cats, horses, cows, sheep, or pigs.

[0656] In some embodiments, this document provides compositions comprising one or more antibodies of the present invention for the prevention, management, treatment, and / or improvement of hOX40L-mediated diseases such as IBD (e.g., ulcerative colitis or Crohn's disease) or their symptoms. IBD symptoms can range from mild to severe and are generally dependent on the part of the intestine involved. Exemplary symptoms of IBD include abdominal cramps and pain, hemorrhagic diarrhea, severe defecation urgency, fever, loss of appetite, weight loss, anemia, fatigue, and / or sores on the lower extremities, ankles, calves, thighs, and arms. Exemplary intestinal complications of IBD include massive bleeding from ulcers, intestinal perforation or rupture, strictures and obstructions, fistulas (abnormal pathways) and perianal diseases, toxic megacolon (e.g., acute obstructive dilatation of the colon), and / or malignancies (e.g., colonic or small bowel cancer). Exemplary extraintestinal complications of IBD include arthritis, dermatitis, ocular inflammation, liver and kidney disease, and / or bone loss. Any combination of these symptoms can be prevented, managed, treated, and / or improved using the compositions and methods provided herein.

[0657] In some embodiments, this document provides compositions comprising one or more antibodies of the present invention for the prevention, management, treatment, and / or improvement of hOX40L-mediated diseases such as GVHD or their symptoms. GVHD typically occurs following allogeneic or matched unrelated bone marrow transplantation (BMT).

[0658] In some implementations, GVHD is referred to as acute GVHD. Symptoms of GVHD can develop rapidly and can be mild or severe. In some cases, acute GVHD occurs within approximately 3 months post-transplantation, such as when blood cell counts recover. In some cases, acute GVHD affects the skin, gastrointestinal (GI) tract, and / or liver. For example, in some patients, acute cutaneous GVHD begins with a rash, for example, on the palms, soles, or shoulders. However, the rash can become widespread and can be itchy and painful and / or may blister and peel. Acute hepatic GVHD can affect normal liver function, such as liver enzymes, and can also cause jaundice. If the liver is enlarged, acute hepatic GVHD can also cause the abdomen to become swollen and painful. Finally, symptoms of acute intestinal GVHD (or digestive system GVHD) may include diarrhea, mucus or blood in the stool, cramps or abdominal pain, indigestion, nausea, and / or loss of appetite. Other systemic symptoms of acute GVHD may include anemia, low-grade fever, and / or increased susceptibility to infections. Any combination of these symptoms of acute GVHD can be prevented, managed, treated, and / or improved using the compositions and methods provided herein.

[0659] In other implementations, GVHD is chronic GVHD. Chronic GVHD can occur from approximately 3 months to approximately 1 year or longer after transplantation. Chronic GVHD can be mild or severe and typically includes symptoms similar to those of acute GVHD. Chronic GVHD can affect the skin and digestive system, including the liver, but can also involve other organs and the immune system (e.g., making the patient more susceptible to infection) and / or connective tissue. Symptoms of chronic skin GVHD include rash, dry skin, tight skin, itchy skin, darkening of skin color, thickening of the skin, and / or may affect hair (e.g., hair loss, turning gray) or nails (e.g., hard or brittle nails). Chronic intestinal GVHD can affect the digestive system, oral cavity, esophagus, stomach lining, and / or intestinal lining, and symptoms may include diarrhea, dry mouth or mouth ulcers, painful swallowing, poor gastric nutrient absorption, flatulence, and stomach cramps. Chronic liver GVHD can cause liver damage and scarring (cirrhosis). Chronic GVHD of the eyes can affect the lacrimal glands, causing dryness, burning, pain, or intolerance to bright light. Chronic GVHD of the lungs can cause shortness of breath, wheezing, persistent cough, and / or increased susceptibility to chest infections. Chronic GVHD can affect tendons that connect muscles to bones (e.g., inflammation), making it difficult to straighten or bend your arms and legs. Any combination of these symptoms of chronic GVHD can be prevented, managed, treated, and / or improved using the compositions and methods provided in this article.

Furthermore, the antibodies can be recombinantly fused to the N- or C-terminus of a heterologous polypeptide, or chemically coupled (including covalent and non-covalent coupling) to the polypeptide or other compositions. For example, the antibodies of the present invention can be recombinantly fused to or coupled to molecules used as markers in detection assays, and effector molecules such as heterologous polypeptides, drugs, radioactive nucleotides, or toxins. See, for example, PCT disclosures WO 92 / 08495, WO 91 / 14438, WO 89 / 12624, U.S. Patent No. 5,314,995, and EP 396,387.

[0669] In some embodiments, this document provides a method for reducing or inhibiting the binding of hOX40L to the OX40L receptor or homologous ligand (e.g., OX40) in a subject (e.g., a human subject), comprising administering to the subject an effective amount of an antibody that specifically binds to an hOX40L polypeptide (e.g., cell surface-expressed or soluble hOX40L). In some embodiments, the secretion of hOX40L biological activity in the subject, such as CCL20, IL8 and / or RANTES or INF-γ, TNF-α or IL-2, especially INF-γ or another cytokine disclosed herein, is also reduced, for example, by at least 10, 20, 30, 40, 50 or 60% or 70% or 80% or 90% or 95% or >95%.

[0670] In some embodiments, this document provides a method for reducing or inhibiting the biological activity of hOX40L in a subject (e.g., a human subject), such as interferon-γ, IL-2, CCL20, IL8 and / or RANTES or other cytokines, or the secretion of INF-γ, TNF-α or IL-2, especially INF-γ, comprising administering to the subject an effective amount of an antibody that specifically binds to an hOX40L peptide (e.g., hOX40L expressed on the cell surface), wherein the biological activity of hOX40L is reduced by said antibody.

[0671] In other embodiments, this document provides methods for reducing or inhibiting the binding of hOX40L to the OX40L receptor or homologous ligand (e.g., OX40) in cells expressing hOX40L on their cell surface, comprising contacting cells with an effective amount of specifically binding hOX40L peptides (e.g., cell surface-expressed or soluble hOX40L), such as hOX40L peptides, hOX40L peptide fragments, or antibodies against hOX40L epitopes. In some embodiments, the secretion of hOX40L biological activities in cells, such as interferon-γ, IL-2, CCL20, IL8, and / or RANTES or INF-γ, TNF-α, or IL-2, especially INF-γ or other cytokines disclosed herein, is also reduced.

[0672] In some embodiments, this document provides a method for reducing or inhibiting the secretion of hOX40L biological activity, such as interferon-γ, IL-2, CCL20, IL8 and / or RANTES or other cytokines disclosed herein, in cells having a cell surface-expressed hOX40L receptor (e.g., OX40). This method comprises contacting cells with an effective amount of an antibody that specifically binds to an hOX40L polypeptide (e.g., cell surface-expressed or soluble hOX40L), wherein the hOX40L biological activity is reduced by said antibody.

[0673] In in vitro and in vivo diagnostic and therapeutic methods, the antibodies of the present invention can be used, for example, to purify, detect, and target the hOX40L antigen. For example, the modified antibodies have the use in immunoassays to qualitatively and quantitatively determine hOX40L levels in biological samples. See, for example, Harlow et al., Antibodies: A Laboratory Manual (Cold Spring Harbor Laboratory Press, 2nd ed., 1988) (incorporated herein by reference in its entirety).

[0674] The present invention also provides a method for preventing, managing, treating, and / or improving hOX40L-mediated diseases by administering to a subject an effective amount of an antibody or a pharmaceutical composition comprising the antibody of the present invention. In one aspect, the antibody is substantially purified (i.e., substantially free of substances that limit its effectiveness or produce adverse side effects). In a preferred embodiment, the antibody is a fully human monoclonal antibody, such as a fully human monoclonal antagonistic antibody. The subject administering the therapy is preferably a mammal such as a non-primate (e.g., a cow, pig, horse, cat, dog, rodent, mouse, or rat) or a primate (e.g., a monkey such as a rhesus monkey or a cynomolgus monkey or a human). In one preferred embodiment, the subject is a human. In another embodiment, the subject is a human infant or a premature human infant. In yet another embodiment, the subject is a person suffering from an hOX40L-mediated disease.

[0675] Various delivery systems are known and can be used to administer prophylactic or therapeutic agents (e.g., the antibodies of the present invention), including but not limited to encapsulation in liposomes, microparticles, microcapsules, recombinant cells capable of expressing antibodies, receptor-mediated endocytosis (see, for example, Wu and Wu, J. Biol. Chem. 262: 4429-4432 (1987)), and nucleic acids constructed as part of retroviruses or other vectors. Methods of administering prophylactic or therapeutic agents (e.g., the antibodies of the present invention) or pharmaceutical compositions include, but are not limited to, parenteral administration (e.g., intradermal, intramuscular, intraperitoneal, intravenous, and subcutaneous), epidural, and mucosal administration (e.g., intranasal and oral routes). In one specific embodiment, prophylactic or therapeutic agents (e.g., the antibodies of the present invention) or pharmaceutical compositions are administered intranasally, intramuscularly, intravenously, or subcutaneously. Prophylactic or therapeutic agents or compositions can be administered via any conventional route, such as by infusion or rapid concentration, through epithelial or mucosal linings (e.g., oral mucosa, intranasal mucosa, rectal and intestinal mucosa, etc.), and can be administered together with other bioactive agents. Application can be systemic or localized. Alternatively, pulmonary administration can be used, for example, by using an inhaler or nebulizer and formulating a nebulizer. See, for example, U.S. Patents 6,019,968, 5,985,320, 5,985,309, 5,934,272, 5,874,064, 5,855,913, 5,290,540, and 4,880,078; and PCT Publications WO 92 / 19244, WO 97 / 32572, WO 97 / 44013, WO 98 / 31346, and WO 99 / 66903, each of which is incorporated herein by reference in its entirety.

[0676] In one specific embodiment, it is desirable to apply a preventative or therapeutic agent, or the pharmaceutical composition of the present invention, topically to the area requiring treatment. This can be achieved, for example, but not limited to, local infusion, surface application (e.g., via nasal spray), injection, or by means of an implant, which may be a porous, non-porous, or gelatinous material, including membranes such as silicone rubber membranes or fibers. Preferably, when administering the antibodies of the present invention, care must be taken to use materials that do not absorb the antibodies.

[0677] In another embodiment, the preventive or therapeutic agent or the composition of the present invention may be delivered in vesicles, especially liposomes (see Langer, 1990, Science 249: 1527-1533; Treat et al., Liposomes in the Therapy of Infectious Disease and Cancer, Lopez-Berestein and Fidler (eds.), Liss, New York, pp. 353-365 (1989); Lopez-Berestein, ibid., pp. 317-327; generally see sources ibid.).

[0678] In another embodiment, the preventive or therapeutic agent or the composition of the present invention can be delivered in a controlled-release or sustained-release system. In one embodiment, controlled-release or sustained-release can be achieved using a pump (see Langer, above; Sefton, 1987, CRC Crit. Ref. Biomed. Eng. 14: 20; Buchwald et al., 1980, Surgery 88: 507; Saudek et al., 1989, N. Engl. J. Med. 321: 574). In another embodiment, the controlled or sustained release of a preventive or therapeutic agent (e.g., the antibody of the present invention) or a composition of the present invention can be achieved using polymeric materials (see, for example, Medical Applications of Controlled Release, Langer and Wise (eds.), CRC Pres., Boca Raton, Fla. (1974); Controlled Drug Bioavailability, Drug Product Design and Performance, Smolen and Ball (eds.), Wiley, New York (1984); Ranger and Peppas, 1983, J., Macromol. Sci. Rev. Macromol. Chem. 23: 61; see also Levy et al., 1985, Science). 228:190; During et al., 1989, Ann. Neurol. 25:351; Howard et al., 1989, J. Neurosurg. 71:105); U.S. Patent No. 5,679,377; U.S. Patent No. 5,916,597; U.S. Patent No. 5,912,015; U.S. Patent No. 5,989,463; U.S. Patent No. 5,128,326; PCT Publication No. WO 99 / 15154; and PCT Publication No. WO 99 / 20253. Examples of polymers used in sustained-release formulations include, but are not limited to, poly(hydroxyethyl 2-methacrylate), poly(methyl methacrylate), poly(acrylic acid), poly(ethylene-co-vinyl acetate), poly(methacrylic acid), polyglycolic acid (PLG), polyanhydride, N-vinylpyrrolidone, poly(vinyl alcohol), polyacrylamide, poly(ethylene glycol), polylactide (PLA), poly(lactide-co-glycolic acid) (PLGA), and polyorthoesters. In a preferred embodiment, the polymer used in the sustained-release formulation is inert, free of leaching impurities, storage-stable, sterile, and biodegradable.In another embodiment, the controlled-release or sustained-release system may be placed near the therapeutic target, i.e., the nasal passage or lungs, thus requiring only a portion of the systemic dose (see, for example, Goodson, in Medical Applications of Controlled Release, Vol. 2 above, pp. 115-138 (1984)). Langer (1990, Science 249: 1527-1533) provides a comprehensive overview of controlled-release systems. Any techniques known to those skilled in the art can be used to prepare sustained-release formulations comprising one or more antibodies of the present invention. See, for example, U.S. Patent No. 4,526,938, PCT Publication WO 91 / 05548, PCT Publication WO 96 / 20698, Ning et al., 1996, “Intratumoral Radioimmunotherapy of a Human Colon Cancer Xenograft Using a Sustained-Release Gel,” Radiotherapy & Oncology 39: 179-189; Song et al., 1995, “Antibody Mediated Lung Targeting of Long-Circulating Emulsions,” PDA Journal of Pharmaceutical Science & Technology 50: 372-397; Cleek et al., 1997, “Biodegradable Polymeric Carriers for a bFGF Antibody for Cardiovascular Application,” Pro. Int'l. Symp. Control. Rel. Bioact. Mater. 24: 853-854; and Lam et al., 1997, “Microencapsulation of Recombinant Humanized Monoclonal Antibody for Local Delivery, Proc. Int'l. Symp. ControlRel. Bioact. Mater. 24: 759-760, each of which is incorporated herein by reference in its entirety.

[0679] In one specific embodiment, when the composition of the present invention is a nucleic acid encoding a preventive or therapeutic agent (e.g., the antibody of the present invention), it can be administered in vivo, for example, by using a retroviral vector (see U.S. Patent No. 4,980,286) as part of a suitable nucleic acid expression vector and administering it to make it intracellular, or by direct injection, or by using microparticle bombardment (e.g., a gene gun; Biolistic, DuPont), or by coating it with lipids or cell surface receptors or transfection agents, or by administering it in combination with a homeobox-like peptide known to enter the cell nucleus (see, for example, Joliot et al., 1991, Proc. Natl. Acad. Sci. USA 88: 1864-1868), to promote the expression of the preventive or therapeutic agent encoded therein. Alternatively, the nucleic acid can be introduced into cells and expressed by homologous recombination into the host cell DNA.

[0680] In one specific embodiment, the composition of the present invention comprises one, two, or more antibodies or fragments of the present invention. In another embodiment, the composition of the present invention comprises one, two, or more antibodies or fragments of the present invention and a preventive or therapeutic agent other than the antibody of the present invention. Preferably, the agent is known for, or has been or is currently used for, the prevention, management, treatment, and / or improvement of hOX40L-mediated diseases. In addition to the preventive or therapeutic agent, the composition of the present invention also comprises a carrier.

[0681] The compositions of the present invention comprise bulk pharmaceutical compositions for use in preparing unit-dose pharmaceutical compositions (e.g., compositions suitable for administration to a subject or patient). In a preferred embodiment, the compositions of the present invention are pharmaceutical compositions. Such compositions comprise a preventive or therapeutically effective amount of one or more preventive or therapeutic agents (e.g., antibodies or other preventive or therapeutic agents of the present invention) and a pharmaceutically acceptable carrier. Preferably, the pharmaceutical composition is formulated for administration to a subject via a route suitable for administration.

[0682] In one specific implementation, the term "carrier" refers to a diluent, adjuvant (e.g., Freund's adjuvant (complete and incomplete)), excipient, or medium that is administered with the therapeutic agent. Such drug carriers can be sterile liquids, such as water and oils, including petroleum, animal, plant, or synthetic oils, such as peanut oil, soybean oil, mineral oil, sesame oil, etc. Water is the preferred carrier when the drug composition is administered intravenously. Saline solutions and aqueous solutions of dextran and glycerol can also be used as liquid carriers, particularly for injectable solutions. Suitable drug excipients include starch, glucose, lactose, sucrose, gelatin, malt, rice, flour, chalk, silica gel, sodium stearate, glyceryl monostearate, talc, sodium chloride, skim milk powder, glycerol, propylene, glycol, water, ethanol, etc. If desired, the composition may also contain small amounts of wetting or emulsifying agents or pH buffers. These compositions can be in the form of solutions, suspensions, emulsions, tablets, pills, capsules, powders, sustained-release formulations, etc. Oral formulations may include standard carriers such as pharmaceutical-grade mannitol, lactose, starch, magnesium stearate, sodium saccharin, cellulose, magnesium carbonate, etc. Examples of suitable drug carriers are described in Remington's Pharmaceutical Sciences (1990), Mack Publishing Co., Easton, Pa. Such compositions will contain a prophylactic or therapeutically effective amount of antibody, preferably in purified form, along with an appropriate amount of carrier, to provide a form suitable for appropriate administration to the patient. The formulation should be appropriate for the mode of administration.

[0683] In a preferred embodiment, the composition is formulated according to a standard procedure suitable for intravenous administration of pharmaceutical compositions to humans. Typically, compositions for intravenous administration are solutions in sterile isotonic buffers. If necessary, the composition may also include a solubilizer and a local anesthetic such as lignocaine to reduce pain at the injection site. However, such compositions can be administered via routes other than intravenous administration.

[0684] Typically, the components of the compositions of this invention are provided individually or mixed together in unit doses, for example, as lyophilized powder or anhydrous concentrate in a sealed container such as an ampoule or sachet indicating the amount of active agent. When the composition is to be administered by infusion, it can be dispersed in an infusion bottle containing pharmaceutical-grade sterile water or saline. When the composition is to be administered by injection, a single ampoule of sterile water or saline for injection can be provided so that the components can be mixed prior to administration.

[0685] The present invention also specifies that the antibodies of the present invention be packaged in a sealed container, such as an ampoule or sachet, indicating the amount of antibody. In one embodiment, the antibody is provided in a sealed container as a dry sterile lyophilized powder or anhydrous concentrate and can be rehydrated, for example, with water or saline to an appropriate concentration for administration to a subject. Preferably, the antibody is provided in a sealed container as a dry sterile lyophilized powder in unit doses of at least 0.1 mg, at least 0.5 mg, at least 1 mg, at least 2 mg, or at least 3 mg, and more preferably at least 5 mg, at least 10 mg, at least 15 mg, at least 25 mg, at least 30 mg, at least 35 mg, at least 45 mg, at least 50 mg, at least 60 mg, at least 75 mg, at least 80 mg, at least 85 mg, at least 90 mg, at least 95 mg, or at least 100 mg. The lyophilized antibody can be stored in its original container between 2 and 8°C and the antibody can be administered within 12 hours, preferably within 6 hours, 5 hours, 3 hours, or 1 hour after rehydration. In an alternative embodiment, the antibody is provided in liquid form in a closed container indicating the amount and concentration of the antibody. Preferably, the antibody in liquid form is provided in a closed container at a concentration of at least 0.1 mg / ml, at least 0.5 mg / ml, or at least 1 mg / ml, and more preferably at least 5 mg / ml, at least 10 mg / ml, at least 15 mg / ml, at least 25 mg / ml, at least 30 mg / ml, at least 40 mg / ml, at least 50 mg / ml, at least 60 mg / ml, at least 70 mg / ml, at least 80 mg / ml, at least 90 mg / ml, or at least 100 mg / ml.

[0686] The compositions of the present invention can be formulated into neutral or salt forms. Pharmaceutically acceptable salts include salts formed with anions such as those derived from hydrochloric acid, phosphoric acid, acetic acid, oxalic acid, tartaric acid, etc., and salts formed with cations such as those derived from sodium, potassium, ammonium, calcium, ferric hydroxide, isopropylamine, triethylamine, 2-ethylaminoethanol, histidine, procaine, etc.

[0687] The amount of a therapeutic agent (e.g., the antibody of the present invention) or a composition of the present invention that will be effective in the prevention, management, treatment and / or remission of hOX40L-mediated diseases can be determined using standard clinical techniques.

[0688] Therefore, a concentration of about 0.1 μg / ml to about 450 μg / ml can be administered to a patient, and in some embodiments at least 0.1 μg / ml, at least 0.2 μg / ml, at least 0.4 μg / ml, at least 0.5 μg / ml, at least 0.6 μg / ml, at least 0.8 μg / ml, at least 1 μg / ml, at least 1.5 μg / ml, and more preferably at least 2 μg / ml, at least 5 μg / ml, at least 10 μg / ml, at least 15 μg / ml, at least 20 μg / ml, at least 25 μg / ml. Antibodies or compositions at serum titers of at least 30 μg / ml, at least 35 μg / ml, at least 40 μg / ml, at least 50 μg / ml, at least 75 μg / ml, at least 100 μg / ml, at least 125 μg / ml, at least 150 μg / ml, at least 200 μg / ml, at least 250 μg / ml, at least 300 μg / ml, at least 350 μg / ml, at least 400 μg / ml, or at least 450 μg / ml are intended for the prevention, management, treatment, and / or relief of hOX40L-mediated disease. Alternatively, in vivo assays may be used to help identify the optimal dose range. The precise dose used in the formulation will also depend on the route of administration and the severity of hOX40L-mediated disease, and should be determined based on the physician's judgment and the individual patient's condition.

[0689] The effective dose can be inferred from the dose-response curves obtained from in vitro or animal model testing systems.

[0690] For the antibodies of the present invention, the dosage administered to a patient is typically from 0.1 mg / kg to 100 mg / kg of patient body weight. In some embodiments, the dosage administered to a patient is from about 1 mg / kg to 75 mg / kg of patient body weight. Preferably, the dosage administered to a patient is between 1 mg / kg and 20 mg / kg of patient body weight, more preferably between 1 mg / kg and 5 mg / kg of patient body weight. Generally, human antibodies have a longer half-life in the human body than antibodies from other species due to the immune response to exogenous peptides. Therefore, lower doses of human antibodies and less frequent administration are often possible. Furthermore, the dosage and frequency of administration of the antibodies of the present invention can be reduced by modifications such as lipolysis to enhance antibody absorption and tissue penetration.

[0691] In one embodiment, the antibody or fragment of the present invention is administered 5, 4, 3, 2 times, or preferably once, at a dose of about 100 mg / kg or less, about 75 mg / kg or less, about 50 mg / kg or less, about 25 mg / kg or less, about 10 mg / kg or less, about 5 mg / kg or less, about 1 mg / kg or less, about 0.5 mg / kg or less, or about 0.1 mg / kg or less, to manage hOX40L-mediated disease. In some embodiments, the antibody of the present invention is administered about 1-12 times, wherein the dose is determined by a physician and may be administered (e.g.) weekly, every two weeks, monthly, every two months, every three months, etc., as necessary. In some embodiments, a lower dose (e.g., 1-15 mg / kg) may be administered more frequently (e.g., 3-6 times). In other embodiments, a higher dose (e.g., 25-100 mg / kg) may be administered less frequently (e.g., 1-3 times). However, as will be apparent to those skilled in the art, other dosages and regimens are readily determined and are within the scope of the present invention.

[0692] In one specific embodiment, the antibody or fragment of the present invention in a sustained-release formulation is administered to a subject, preferably to a human, at a dose of about 100 mg / kg, about 75 mg / kg or less, about 50 mg / kg or less, about 25 mg / kg or less, about 10 mg / kg or less, about 5 mg / kg or less, about 1 mg / kg or less, about 0.5 mg / kg or less, or about 0.1 mg / kg or less, to prevent, manage, treat, and / or improve hOX40L-mediated disease. In another specific embodiment, the antibody pills of the present invention, which are not in a sustained-release formulation, are administered to a subject, preferably to a human, at a dose of about 100 mg / kg, about 75 mg / kg or less, about 50 mg / kg or less, about 25 mg / kg or less, about 10 mg / kg or less, about 5 mg / kg or less, about 1 mg / kg or less, about 0.5 mg / kg or less, or about 0.1 mg / kg or less, to prevent, manage, treat, and / or improve hOX40L-mediated disease, and after a certain period of time, the subject is administered (e.g., nasally or intramuscularly) two, three, or four times (preferably once) the antibody of the present invention at a dose of about 100 mg / kg, about 75 mg / kg or less, about 50 mg / kg or less, about 25 mg / kg or less, about 10 mg / kg or less, about 5 mg / kg or less, about 1 mg / kg or less, about 0.5 mg / kg or less, or about 5 mg / kg or less.
