Description: EP4 RECEPTOR INHIBITORS TO TREAT RHEUMATOID ARTHRITIS Field of the Invention The present invention features methods of treating rheumatoid arthritis by administering an agent that inhibits prostaglandin EP4 receptor activity. The invention also includes methods of identifying agents that selectively inhibit prostaglandin EP4 receptor activity in vivo. Background Prostaglandin E 2 (PGE 2 ) is a potent modulator involved in the pathogenesis of arthritis. PGE 2 binds to at least four subtypes of PGE receptor, designated EPl, EP2, EP3, and EP4. Molecular studies have revealed that all subtypes are 7-transmembrane spanning receptors that belong to the G-protein coupled receptor superfamily (Robert et al., Am. Soc. Pharm. Exp. Ther. 46: 205-29, 1994). EPl activation stimulates the release of intracellular calcium via a G protein-mediated mechanism; EP2 and EP4 both activate adenylate cyclase via stimulatory G proteins, but differ in their response to certain ligands; and EP3 inhibits adenylate cyclase via inhibitory G-proteins (Robert et al., supra, Negishi et al., Biochimica Biophys. Acta 1259: 109-20, 1995). To further elucidate the function of the various EP receptors in PGE 2 - mediated signaling, knockout mice strains have been developed in which each of the EP receptors have been targeted for disruption (Stock et al., J. Clin. Invest. 107: 325-31 , 2001 ; Tilley et al., J. Clin. Invest. 103: 1539-45, 1999; Fleming et al., Am. J. Physiol. 275: F955-61 , 1998; Nguyen et al., Nature 390: 78-84, 1997). Summary of the Invention The present invention features methods of treating rheumatoid arthritis. In the first aspect, the invention features a method of treating rheumatoid arthritis in a mammal involving administering an agent that inhibits prostaglandin EP4 receptor (EP4) activity.

Detailed Description The present invention is directed to a method of treating symptoms of rheumatoid arthritis by administering an agent that inhibits EP4 activity. This invention is based upon the discovery that EP4 knockout mice are relatively resistant to developing symptoms of arthritis subsequent to disease induction with administration of an anti-type II collagen antibody (an experimental model for rheumatoid arthritis). The invention also features screening methods to identify agents that inhibit EP4 activity in vivo for use, for example, as anti- rheumatoid arthritis therapeutics. Therapeutic Methods Agents identified as EP4 inhibitors are administered in a dose sufficient to reduce joint inflammation, joint swelling, joint ankylosis, interleukin (IL)-6, and/or serum amyloid A protein (SAA), and/or sufficient to increase joint mobility. Such therapeutically effective amounts will be determined using routine optimization techniques that are dependent on the particular condition to be treated, the condition of the patient, the route of administration, the formulation, the judgment of the practitioner, and other factors evident to those skilled in the art in light of this disclosure. An agent that inhibits EP4 activity can be incoφorated into a therapeutic composition. Such EP4 inhibitors can include small molecules, nucleic acids, e.g., EP4 antisense nucleic acids, amino acids, peptides, carbohydrates, and anti- EP4 antibodies. Preferably, such agents are combined with a pharmaceutically acceptable delivery vehicle or carrier. Examples of EP4 antibodies include, for example, polyclonal, monoclonal, humanized, anti-idiotypic, chimeric or single chain antibodies, Fab, F(ab') 2 , and Fab expression library fragments, scFN molecules, and epitope-binding fragments thereof. An antisense oligonucleotide directed to the EP4 gene or mRΝA to inhibit its expression is made according to standard techniques (see, e.g., Agrawal et al. Methods in Molecular Biology: Protocols for Oligonucleotides and Analogs, Vol. 20 (1993)). As used herein, a pharmaceutically acceptable delivery vehicle includes solvents, dispersion media, coatings, antibacterial and antifungal agents, and isotonic and absoφtion delaying agents that are compatible with pharmaceutical administration. The vehicle may also include other active or inert components, and/or may be targeted to joint tissue by virtue of its composition. A therapeutic composition is formulated to be compatible with its intended route of administration. Νon-limiting examples of routes of administration include parenteral, e.g., intravenous, intradermal, subcutaneous, oral (e.g., by ingestion or inhalation), transdermal (topical), transmucosal, and rectal administration. Solutions or suspensions can be made as described in Remington 's Pharmaceutical Sciences, (18 l 1 ed., Gennaro, ed., Mack Publishing Co., Easton, PA, (1990)). Therapeutic efficacy of such EP4 inhibitors can be determined in light of this disclosure by standard therapeutic procedures in cell cultures or experimental animals, e.g., for determining the ED 50 (the dose therapeutically effective in 50% of the population). The data obtained from the cell culture assays and animal studies can be used in formulating a range of dosage for use in humans. The dosage may vary depending upon the formulation and the route of administration. For any EP4 inhibitor used in the method of the invention, the therapeutically effective dose can be estimated initially from cell culture assays. A dose may be formulated in animal models to achieve a circulating plasma concentration range that includes the IC 5 o as determined in cell culture. Such information can be used to more accurately determine useful doses in humans. Levels in plasma may be measured, for example, by high performance liquid chromatography. The skilled artisan will appreciate that certain factors may influence the dosage and timing required to effectively treat a mammal including, but not limited to, the severity of the disease or disorder, previous treatments, the general health and/or age of the mammal, and other diseases present. Moreover, treatment of a mammal with a therapeutically effective amount of an EP4 inhibitor can include a single treatment or, preferably, can include a series of treatments. For anti-EP4 antibodies, the preferred dosage is generally 10 mg/kg to 20 mg/kg body weight. Generally, partially humanized antibodies and fully human antibodies have a longer half-life within the human body than other antibodies. Accordingly, lower dosages and less frequent administration are possible. Modifications such as lipidation can be used to stabilize antibodies and to enhance uptake and tissue penetration. A method for lipidation of antibodies is described in Cruikshank et al. (J. Acquired Immune Deficiency Syndromes Hum. Retroviral. 14: 193, 1997). EP4 inhibitors (e.g., antagonists) that can be administered include the aryl and heteroaryl fused imidazole compounds of Formula I, as further described below, and as described in U.S. provisional application 60/241,825, filed October 19, 2000, and in Akiyoshi et al., a non-provisional application filed on approximately October 10, 2001 and entitled "Aryl or Heteroaryl Fused Imidazole Compounds as Anti-Inflammatory and Analgesic Agents." Other EP4 inhibitors that can be administered include those disclosed in EP 0985663, WO 00/15608, WO 00/03980, WO 98/55468, WO 00/01874, WO 01/42281 , WO 01/02855, WO 01/10426, WO 00/16760, WO 00/18744, WO 00/16760, WO 00/21532, WO 00/18405, EP 0855389, GB 2330307, and GB 2075503. EXAMPLE A 1. Reduction of Rheumatoid Arthritis Symptoms in EP4 Receptor Knockout Mice Methods Generation of genetically modified mice. EPl receptor knockout (EP1-KO) , EP2-KO, EP3-KO, and EP4-KO mice were generated as previously described (Stock et al., J. Clin. Invest. 107: 325-31, 2001; Tilley et al., J. Clin. Invest. 103: 1539-45, 1999; Fleming et al., Am. J. Physiol. 275: F955-61, 1998; Nguyen et al, Nature 390: 78-84, 1997, respectively). EP1-KO mice were maintained on a DBAl/lacJ genetic background. EP2-KO and EP4-KO mice were maintained on a 129xDBA 2xC57/B16 genetic background. EP2 and EP4 littermate wild type mice (WT) were used as controls. EP3-KO animals were maintained on a 129Sv/Ev genetic background. All experiments were performed on 8- 10 week old mice (approximate weight: 20g). Induction and visual assessment of rheumatoid arthritis. Arthritis was induced in mice using a monoclonal antibody directed against Type II collagen (mAb treatment). The mAb treatment involved an intraperitoneal (i.p.) injection (400 μl, 10 mg/ml) of a monoclonal antibody cocktail (Chemicon International Inc., Temecula, CA) in the mice on Day 0. After 24 hours, mice were injected i.p. with lipopolysaccharide (LPS) (100 μl, 0.25 mg/ml) (Chemicon International Inc.) For 10 days following the antibody injection, arthritis was assessed by the degree of swelling, redness, and ankylosis of the joints. All visual factors were combined into a score of 0-3 per paw and summed for a total score of 0-12 for each animal. Histological assessment. On Day 10 following antibody injection (Day 10), mice were euthanized by C0 2 asphyxiation, and tissue samples were subjected to a comprehensive histological assessment that included evaluations of cartilage structure, cellularity, Safranin-0 staining for acid mucopolysaccharides, and synovial inflammation and hypeφlasia to develop Modified Mankin scores (Mankin, et al., J. Bone and Joint Surgery 53: 523-537, 1971). Originally developed to quantify changes in articular cartilage in humans with osteoarthritis, the Mankin scale was modified for rodents to reflect rodent size and to include synovial inflammation. The scores were based upon a scale of 0-4 (with 4 designated for the most severe form of arthritic symptoms) graded on a relative severity scale developed for the spectrum of lesions observed in these studies. 9A4-immunohistochemical staining was conducted as previously described (Otterness et al., Matrix Biology 18: 331-41, 1999). The scores were graded as follows: score = 0, normal cartilage; score = 4, diffuse staining reflecting severe bone and cartilage damage. Serum collection. Following euthanization, mice were bled by cardiac puncture. Using a gentle vacuum, blood was collected in Microtainer® serum separator tubes (Becton Dickenson, Franklin Lakes, NJ) and spun at l OOOxg for 10 min. at 4°C. The serum fraction was collected and stored at -20°C until assayed for PGE 2 (Cayman Chemical, Ann Arbor, MI), IL-6 (R&D Systems, Inc., Minneapolis, MN), and serum amyloid A (SAA) (Biosource International, Camarillo, CA) levels. Exudate collection. Peritoneal macrophages were collected by removing the skin from the abdomen of Day 10 euthanized mice, and injecting 8 ml of lavage fluid (500 ml Hanks's Balanced Salt Solution, 1 ml 1% EDTA) into the peritoneal cavity. The solution was collected from the peritoneal cavity and placed in 50 ml conical polystyrene tubes on ice. The samples were spun for 10 min. at 300xg at room temperature. Lavage fluid (containing peritoneal exudates) was isolated and stored at -20°C until assayed. Interleukin (IL)-6 and PGE 2 levels were measured as described previously. Total protein content was determined by BCA assay (Pierce Chemical, Rockford, IL). Peritoneal macrophage culture. After the collection of peritoneal macrophages as previously described, the cells were washed twice with lavage solution, and twice with modified DMEM (DMEM, 1% fetal bovine serum, 1% penicillin/streptomycin). The cells were resuspended in 10 ml modified DMEM and the cell concentration was diluted to 10 6 /ml in modified DMEM. Cells were plated in 96-well plates (100 μl/well), and incubated at 37°C, 95% 0 2 , 5% C0 2 for 1-2 hours. After the incubation, the supernatant was removed from the plates by inversion in a sterile tissue culture hood. Each well was washed twice with PBS, and the macrophages were then incubated for 18 hours at 37°C, 95% 0 2 , 5% C0 2 . Supematants from each well were then carefully removed and placed at -20°C until analysis for IL-6 as previously described. β-hexaminidase levels were measured in cell lysates from the remaining macrophages and used to normalize for variability in cell numbers. After collecting the supematants, the peritoneal macrophages were lysed by adding 200 μl/well of lysis buffer (25 mM HEPES, pH 7, 0.5% Triton X-100, 250 mM NaCl and proteinase inhibitors (1 μg/μl pepstatin, 1 μg/μl leupeptin, 0.1 mM phenylmethylsulfonyl fluoride, all available from Sigma Chemical Co., St. Louis, MO). Plates were incubated on ice for 30 min., and lysates were collected. The lysate sample (10 μl) was combined with 50 μl substrate (50 mM sodium citrate, pH 4, 0.2% Triton X-100, 2 mM p-nitrophenyl N-acetyl-beta-D- glucosamine (Sigma Chemical Co.) and incubated at 37°C for 60 min. Reactions were stopped with 100 μl carbonate stop solution (0.11 M Na 2 C0 3 , 0.09 M NaHC0 3 , final pH about 10) and well absorbance was read at 415 nm. Quantitative mRNA determination. Livers and peritoneal macrophages were harvested from Day 10 euthanized mice and snap frozen on dry ice. Total RNA was isolated using Maxiprep columns (Qiagen, Valencia, CA) and stored at -80°C until assayed. Absorbance at 260 and 280 nm were determined to estimate RNA levels and purity. All samples had an A 26 o to A 28 o ratio greater or equal to 1.7. Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and IL-1 mRNA levels were determined by enzyme immunoassay (Quantikine®, R&D systems). GADPH levels were used to normalize IL-1 mRNA levels. EP4 mRNA was measured in WT and EP4-KO liver and peritoneal macrophages by reverse transcription polymerase chain reaction (RT-PCR), using the sense and antisense primers ggtcatcttactcatcgccacctctc (SEQ ID NO: 1) and tcccactaacctcatccaccaacag (SEQ ID NO: 2), respectively (Suzawa, et al. Endocrinology 141: 1554-1559, 2000). Cycling conditions were: 94°C for 2 min.; 30 cycles at 94°C for 30 seconds, 65°C for 30 seconds, and 75°C for 60 seconds; and 72°C for 2 min. Results Visual scores of arthritis. Each strain of knockout mouse and its corresponding WT genetic control was tested for the development of rheumatoid arthritis following mAb treatment. The signs of arthritis in WT mice appeared 3-4 days following mAb treatment and reached their maximum by Day 10. Therefore, the final assessment of arthritis development was performed in all mouse lines on Day 10. All four wild type genetic controls developed comparable scores for arthritis on Day 10, indicating that the differences in genetic background did not lead to detectable differences in disease severity and/or incidence (Figures 1 and 2, respectively). EP1-KO, EP2-KO, and EP3-KO mAb-treated mice did not display any significant differences from their appropriate WT control in the incidence or severity of the arthritic symptoms. By contrast, EP4-KO mAb treated mice demonstrated a significant reduction in the severity of the symptoms (Figure 1), in the number of mice that displayed arthritic symptoms (Figure 2), and in the number of joints affected (Figure 3) as compared to mAb-treated WT controls. The differences in arthritis severity were evident throughout the time course of disease development (Figure 4). Histology. MAb-treated EP4-KO mice also displayed a significantly improved histology as compared to their mAb-treated WT controls as shown by Modified Mankin score (Table 1). MAb-treated WT mice often developed a severe form of arthritis with the formation of multiple erosions on the cartilage surface, cellular hypeφlasia, loss of proteoglycan, and pannus formation. The articular cartilage of the mAb-treated EP4-KO mice were significantly protected from such damage (Table 1). 9A4 immunohistochemical staining, which correlates with type II collagen breakdown, was also increased in the mAb-treated WT mice as compared to mAb-treated EP4-KO mice, indicating an increase in cartilage integrity in the mAb-treated EP4-KO mice (Table 1). Table 1 Clinical biomarkers of arthritis-associated Inflammation. Clinical biomarkers of arthritis were determined in the serum and peritoneal exudates of mAb-treated and non-treated EP4-KO and WT mice. SAA levels were significantly elevated in the WT mAb-treated group as compared to the WT non-treated controls. By contrast, EP4-KO mice did not display any increases in serum levels of this marker of inflammation as a result of mAb treatment (Table 2). Serum levels of IL-6 following mAb treatment were increased in both the mAb treated EP4-KO and WT groups, although the WT group increased to a greater extent (Table 2). Peritoneal exudate levels of IL-6 and PGE2 followed the same pattern (Table 2). These levels in mAb treated EP4-KO mice were increased compared to the non-treated EP4-KO mice, but significantly lower as compared to mAb treated WT mice. Table 2 * p<0.05 by 2-way ANONA and Bonferroni post test In view of the significant differences in levels of inflammatory mediators detected in peritoneal exudates between mAb treated WT and EP4-KO mice, the properties of peritoneal macrophages isolated from these animals were further characterized for IL-6 levels. Under baseline conditions, WT macrophages released significantly more IL-6 than EP4-KO macrophages (8.6 + 0.1 ng/ml/β-hexaminidase OD (n=3) and 5.4 + 0.2 ng/ml/β-hexaminidase OD (n=3), respectively, p<0.05). The integrity of the signaling properties was tested by incubating WT and EP4-KO cells with 1 μg/ml LPS. Under these conditions, there were no detectable differences in IL-6 levels between WT and EP4-KO macrophages (36.4 + 6.7 ng/ml/β- hexaminidase OD (n=3) and 34.9 + 8.2 ng/ml/β-hexaminidase OD (n=3), respectively). mRNA in liver and peritoneal macrophages. The liver and peritoneal macrophages are involved in the synthesis and release of inflammatory mediators. There were no detectable differences in IL- 1 mRΝA levels (IL-1 RΝA (pg)/ GAPDH RΝA (pg)) between non-treated WT and EP4-KO mice (36.4+6.7 (n=4), and 34.9+8.2 (n=4), respectively). However, following mAb treatment, levels were significantly reduced in the EP4-KO mice (57.4+4.4 ( n =4) for WT, 20.6+2.7 (n=4) for EP4-KO, p<0.05 by 2-way ANONA). Measures of EP4 mRΝA confirmed EP4 expression in WT liver and peritoneal macrophages. As expected, no EP4 mRΝA was detected in the EP4- KO samples. 2. Reduction of Rheumatoid Arthritis Symptoms In EP4 Antagonist- Treated Rats Methods Induction of adjuvant arthritis. Arthritis was induced in male, Sprague-Dawley rats (115-145g, Japan SLC Inc., Shizuoka, Japan) on Day 0 by an injection of 300 μg of M. Tuberculosis H37 RA (Difco Laboratories Inc., Detroit, MI) in 100 μl of liquid paraffin (Wako Pure Chemical Industries, Ltd., Osaka, Japan) into the right hind footpad (Νeuroscience 78: 843-850, 1997) on Day 0. Compound treatment. EP4 antagonists included within Formula I as described above (compound A and B, 60 mg/kg, bid), piroxicam (Feldene®, 3 mg/kg, qd), rofecoxib (Nioxx®, 1.5 mg/kg, bid), and control vehicle were each suspended in 0.1 % mefhylcellulose (MC) and perorally administered separately in five groups of rats from day 0 to day 14 in a volume of 1 ml per 100 g body weight. Evaluation. Hindpaw volume was measured by an hydroplethysmometer (Ugo Basile, Comerio, Italy) on Day 0, immediately before adjuvant injection, and on Days 1 , 4, 7, 1 1 and 14 after injection. Paw swelling (%) was calculated as follows (Agents and Actions 34: 63-65, 1991): swelling (%) = (Day X volume (ml) — Day 0 volume (ml)} / Day 0 volume (ml) x lOO. On Day 14, the arthritic score of each paw was evaluated as described below. The total arthritic score for each animal was the sum of the score for all four limbs (Agents and Actions 27: 356-358, 1989). A score of 0 was used for limbs with no arthritic symptoms; a score of 1 was used for limbs with redness and swelling in two or less digits or locally in part of the foot pad; a score of 2 was used for limbs with redness and swelling of more than two digits, or in two or less digits and locally in part of the foot pad, or in the whole foot pad; a score of 3 was used for limbs with redness and swelling in more than two digits and locally in part of the foot pad, or in less than two digits and the whole foot pad; a score of 4 was used for limbs with redness and swelling in more than two digits and in the whole foot pad. Statistical analysis. Data are expressed as mean±SEM (n=8) and statistical significance was evaluated by t-test ox Mann-Whitney Rank Sum test (*p<0.05, **p<0.01, ***p<0.005 significantly different from disease group untreated with compound). Results Paw edema of adjuvant arthritis. There was a rapid and time-dependent increase in paw volume in the ipsilateral paw following injection of adjuvant. From Day 9 to Day 12, the edema symptoms of arthritis had spread to joints in the whole body, not just the joints at the site of injection. Groups treated with EP4 antagonist compound A and compound B demonstrated significantly suppressed edema formation in the ipsilateral paws during the entire experimental period (Figure 5 and Figure 6). On day 14, compound A and compound B inhibited paw edema by 45.6 and 47.1%, respectively (Table 3). These effects were comparable to that of the piroxicam treated group. The rofecoxib-treated group showed a weaker activity. Table 3 Arthritic score As shown in Figure 7, the groups treated with EP4 antagonist compound A and compound B demonstrated significantly reduced arthritics score on day 14, reduced by 34.1% and 29.6%, respectively (Table 4). Table 4 In summary, these results demonstrate that treatment with an EP4 antagonist produces an anti-inflammatory effect in chronic inflammatory diseases such as rheumatoid arthritis and inhibits the formation of arthritis.

First, agents are identified which selectively inhibit EP4 activity or selectively bind EP4 over EPl, EP2, and EP3 activity, as determined by functional studies and/or by selective binding studies. Briefly, cells are obtained that predominantly express only one of the EP receptor isoforms. For example, four strains of host cells (e.g., HEK-293 cells) can be genetically engineered to express one of the EP receptors: EPl, EP2, EP3, and EP4. Such cells can be used, in the presence and absence of test agents, for EP receptor functional studies or EP receptor binding studies as reported in the art (see, e.g., Cameron et al., EP 1121939, Fabre et al., J. Clin. Invest. 107: 603-10, 2001, Sakuma et al., J. Bone Miner. Res. 15: 218-27, 2000, and Ungrin et al., Mol. Pharmacol. 59: 1446-56, 2001). Second, agents identified as selectively inhibiting EP4 activity or selectively binding EP4 are administered to test animals in which rheumatoid arthritis is experimentally induced (e.g., via injection of type II collagen, injection of an anti-type II collagen antibody, or antigen-induced arthritis). Test agents that reduce joint inflammation, joint swelling, joint ankylosis, interleukin (IL)-6, and/or serum amyloid A protein (SAA), and/or increase joint mobility are identified as agents that inhibit EP4 activity at the in vivo level. The test agents used for screening assays of the present invention may be selected individually or obtained from a compound library. Such agents include peptides, combinatorial chemistry-derived molecular libraries made of D- and/or L-configuration amino acids, phosphopeptides, anti-EP4 antibodies, EP4 antisense nucleic acids, and small organic and inorganic compounds. Libraries include biological libraries, libraries of natural compounds, peptoid libraries (libraries of molecules having the functions of peptides, but with novel, non-peptide backbones which are resistant to enzymatic degradation yet remain bioactive) (see, e.g., Zuckermann, J. Med. Chem. 37: 2678-85, 1994), spatially addressable parallel solid phase or solution phase libraries, synthetic library methods requiring deconvolution, the "one-bead one- compound" library method, and synthetic library methods using affinity chromatography selection. Examples of methods for the synthesis of molecular libraries can be found in the art, for example, in DeWitt et al., Proc. Natl. Acad. Sci. 90: 6909, 1993; Erd et al., Proc. Natl. Acad. Sci. 91: 11422, 1994; Zuckermann et al., J. Med. Chem. 37: 2678,1994; Cho et al., Science, 261 : 1303, 1995; Carrell et al., Angew. Chem. Int. Ed. Engl. 33: 2061, 1994; and Gallop et al., J. Med. Chem. 37: 1233, 1994. Libraries of compounds may be presented in solution (e.g., Houghten, Biotechniques, 13: 412-421, 1992), or on beads (Lam, Nature 354: 82-84, 1991), on chips (Fodor, Nature 364: 555-556, 1993), bacteria or spores (Ladner, U.S. Patent No. 5,223,409), plasmids (Cull et al., Proc. Natl. Acad. Sci. USA. 89: 1865-1869, 1992) or on phage (Scott et al., Science 249: 386- 390, 1990; Devlin, Science 249: 404-406, 1990; Cwirla et al., Proc. Natl. Acad. Sci. (USA) 87: 6378-6382, 1990; Felici, J. Mol. Biol. 222: 301-310, 1991 ; Ladner, supra).
