Patents Act 1990 COMPLETE SPECIFICATION Standard Patent Applicant CornbinatoRx, In corpora ted Invention Title: COMBINATIONS FOR THE TREATMENT OF IMMUNOINFLAMMATORY DISORDERS The following statement is a full description of this invention, including the best method for performing it known to me/us: P52787 AU I PaSet FAN Appft~ction 2008.3-17 doc (M) 00 COMBINATIONS FOR THE TREATMENT OF SIMMUNOINFLAMMATORY DISORDERS Field of the Invention NC- 5 The invention relates to the treatment of immunoinflammatory disorders.
Background of the Invention SImmunoinflammatory disorders rheumatoid arthritis, psoriasis, 00 ulcerative colitis, Crohn's disease, stroke-induced brain cell death, ankylosing spondylitis, fibromyalgia, and inflammatory dermatoses, asthma, multiple sclerosis, type I diabetes, systemic lupus erythematosus, scleroderma, systemic sclerosis, and Sjbgren's syndrome) are characterized by dysregulation of the immune system and inappropriate activation of body's defenses resulting in damage to healthy tissue.
One percent of humans world-wide are afflicted with rheumatoid arthritis a relentless, progressive disease causing severe swelling, pain, and eventual deformity and destruction of joints. According to the Arthritis Foundation, rheumatoid arthritis currently affects over two million Americans, of which women are three times more likely to be afflicted. Rheumatoid arthritis is characterized by inflammation of the lining of the joints and/or other internal organs, and the presence of elevated numbers of lymphocytes and high levels of proinflammatory cytokines.
Diagnosis of RA generally includes: morning stiffness in joints lasting at least one hour before improvement, (ii) arthritis of three or more joint areas having simultaneously soft tissue swelling or fluid; (iii) arthritis of at least one hand joint; (iv) symmetric arthritis, simultaneous involvement of the same joint area on both sides of the body; rheumatoid nodules; (vi) abnormal serum rheumatoid factor; and (vii) radiographic changes typical of rheumatoid arthritis on posteroanterior hand and wrist radiographs, which include erosions or unequivocal bony decalcification localized in or most marked adjacent to the involved joints. Patients are classified as having RA if at least four of these seven N\Miclbourn\Casc\Patent\S2OO.S2999\PS2767AU I\Spec s\Spccificaion filedduc -3- 0 criteria, and through (iv) must have been present for at least six weeks.
(American College of Rheumatology, 1987 Criteria for the Classification of Acute Arthritis of Rheumatoid Arthritis, based on Amett FC et al., Arthritis SRheum. 1988; 31:315-324). Pain per se is not required for the diagnosis of RA.
r, 5 Treatment of RA generally includes anti-inflammatory strategies directed at suppressing the clinical manifestations of joint inflammation, including synovial thickening, joint tenderness, and joint stiffness. Drugs used to address these signs and symptoms generally include non-steroidal anti-inflammatory 00 drugs (NSAIDs; detoprofen, diclofenac, diflunisal, etodolac, fenoprofen, flurbiprofen, ibuprofen, indomethacin, ketoprofen, meclofenameate, mefenamic acid, meloxicam, nabumeone, naproxen sodium, oxaprozin, piroxicam, sulindac, tolmetin, celecoxib, rofecoxib, aspirin, choline salicylate, salsalte, and sodium and magnesium salicylate)--these drugs may be adequate for mild RA, but do not appear to alter the longterm course of the disease; and (ii) steroids cortisone, dexamethasone, hydrocortisone, methylprednisolone, prednisolone, prednisone, triamcinolone).
Treatment for RA may also include strategies directed at limiting the long term joint damage and deformity caused by the inflammation in the joints. Such treatments are generally described as DMARDs, disease modifying antirheumatic drugs cyclosporine, azathioprine, methotrexate, leflunomide, cyclophosphamide, hydroxychloroquine, sulfasalazine, D-penicillamine, minocycline, gold, etanercept (soluble TNF receptor) and infliximab (a chimeric monoclonal anti-TNF antibody)).
There is a need to develop new regimens for the treatment of immunoinflammatory disorders.
Summary of the Invention We have discovered that the combination of tetra-substituted pyrimidopyrimidines, such as dipyridamole (also known as 2,6bis(diethanolamino)-4,8-dipiperidinopyrimido(5,4-d)pyrimidine), and corticosteroids, such as fludrocortisone (as known as 9-alpha-fluoro- 11-beta, 17alpha, 21-trihydroxy-4-pregnene-3,20-dione acetate) or prednisolone (also known N Melborn\CaseTPatent\520OOO52999\P52767 AU.

Administration of each compound can occur, 1 to 5 times each day, or as necessary to alleviate symptoms.
Accordingly, this invention also features pharmaceutical compositions, pharmaceutical packs, and kits containing one or more tetra-substituted pyrimidopyrimidine and one or more corticosteroid. The methods and compositions (pharmaceutical compositions and pharmaceutical packs) of the invention may feature higher order combinations of tetra-substituted pyrimidopyrimidines and corticosteroids. Specifically, one, two, three, or more tetra-substituted pyrimidopyrimidines may be combined with one, two, three, or more corticosteroids. In preferred embodiments, the tetra-substituted N \Melbourne\CAsesaer\Pate\52O .52999\P52767 AUI\Spc is\Specification fileddoc 0 0 pyrimidopyrimidine, the corticosteroid, or both are approved by the United States SFood and Drug Administration (USFDA) for administration to a human.
Exemplary tetra-substituted pyrimidopyrimidines that are useful in the Smethods and compositions of this invention include, for example, 2,6disubstituted 4,8-dibenzylaminopyrimido[5,4-d]pyrimidines. Particularly useful tetra-substituted pyrimidopyrimidines include dipyridamole (also known as 2,6bis(diethanolamino)-4,8-dipiperidinopyrimido(5,4-d)pyrimidine), mopidamole, Sdipyridamole monoacetate, NU3026 (2,6-di-(2,2-dimethyl-1,3-dioxolan-4-yl)- O methoxy-4,8-di-piperidinopyrimidopyrimidine), NU3059 (2,6-bis-(2,3dimethyoxypropoxy)-4,8-di-piperidinopyrimidopyrimidine), NU3060 (2,6bis[N,N-di(2-methoxy)ethyl]-4,6-di-piperidinopyrimidopyrimidine), and NU3076 (2,6-bis(diethanolamino)-4,8-di-4-methoxybenzylaminopyrimidopyrimidine).
The invention described herein has been exemplified using the corticosteroids fludrocortisone (as known as 9-alpha-fluoro- 11-beta, 17-alpha, 21 -trihydroxy-4-pregnene-3,20-dione acetate) and prednisolone (also known as 1dehydrocortisol; 1-dehydrohydrocortisone; 1,4-pregnadiene- l beta, 17alpha, 21triol-3,20-dione; and 1 lbeta, 17alpha, 21-trihydroxy-1,4-pregnadiene-3,20dione); however, a skilled artisan will recognize that structural and functional analogs of these corticosteroids can also be used in combination with the tetrasubstituted pyrimidopyrimidines in the methods and compositions of the present invention. Other useful corticosteroids may be identified based on the shared structural features and apparent mechanism of action among the corticosteroid family.
The tetra-substituted pyrimidopyrimidine and the corticosteroid may be administered in the same or different pharmaceutical formulations.
Pharmaceutical compositions or components of the pharmaceutical pack may be administered by the same or different routes and include oral, rectal, intravenous, intramuscular, subcutaneous, intra-articular, inhalation, topical or transdermal, vaginal, and ophthalmic administration.
Dosages of the tetra-substituted pyrimidopyrimidine and the corticosteroid may be determined individually; however, tetra-substituted pyrimidopyrimidine N:\Mclbourne\Cascs\Pateni\52000.52999\P52767 AU ISpecis\Spccification iled doc 00 are typically administered to human patients at about 0.5-800 mg/day, 18-600 Smg/day, or 50-400 mg/day. Corticosteroids are typically administered at about 0.1-1500 mg/day, 0.5-30 mg/day, or 0.5-10 mg/day. Low doses of corticosteroids 10 mg/day or less of prednisolone, or its equivalent) are preferred. The total daily dosage of the tetra-substituted pyrimidopyrimidine and the corticosteroid may be administered in one, two, three, four, or more dosages. There is no need for the tetra-substituted pyrimidopyrimidine and the corticosteroid to be Sadministered in the same number of daily doses. Further, there is no need for the 00 tetra-substituted pyrimidopyrimidine and/or the corticosteroid to be administered every day or by the same route of administration. For example, the tetrasubstituted pyrimidopyrimidine may be administered by intravenous injection every second day and the corticosteroid administered by topical application twice every day. Accordingly, when administered in different compositions, pharmaceutical formulations, packs, and kits are prepared in form and dosage suitable for achieving the desired treatment regimen.
The diseases or disorders treated using the methods and compositions of this invention are immunoinflammatory disorders including, for example, rheumatoid arthritis, psoriasis, ulcerative colitis, Crohn's disease, stroke-induced brain cell death, ankylosing spondylitis, fibromyalgia, asthma, multiple sclerosis, type I diabetes, systemic lupus erythematosus, scleroderma, systemic sclerosis, inflammatory dermatoses, or Sjogren's syndrome.
The application also generally describes a method for identifying compounds useful for treating a patient having an immunoinflammatory disorder.
The method includes the steps of: contacting immune cells in vitro with an immunomodulatory compound selected from the group of a tetra-substituted pyrimidopyrimidine having formula or a corticosteroid; and (ii) a candidate compound, and determining whether the immune response is modulated relative to immune cells contacted with the immunomodulatory compound but not contacted with the candidate compound, and immune cells contacted with the candidate compound but not with the immunomodulatory compound.

c Therapy Combination therapy according to the invention may be performed alone or in conjunction with another therapy and may be provided at home, the doctor's office, a clinic, a hospital's outpatient department, or a hospital. Treatment 00 10 generally begins at a hospital so that the doctor can observe the therapy's effects 0 closely and make any adjustments that are needed. The duration of the combination therapy depends on the type of immunoinflammatory disorder being treated, the age and condition of the patient, the stage and type of the patient's disease, and how the patient responds to the treatment. Additionally, a person having a greater risk of developing an immunoinflammatory disorder a person who is genetically predisposed or previously had an immunoinflammatory disorder) may receive prophylactic treatment to inhibit or delay an inflammatory response.
The dosage, frequency and mode of administration of each component of the combination can be controlled independently. For example, one compound may be administered orally three times per day, while the second compound may be administered intramuscularly once per day. Combination therapy may be given in on-and-off cycles that include rest periods so that the patient's body has a chance to recovery from any as yet unforeseen side-effects. The compounds may also be formulated together such that one administration delivers both compounds.
Formulation of pharmaceutical compositions The administration of each compound of the combination may be by any suitable means that results in a concentration of the compound that, combined with the other component, is antiinflammatory upon reaching the target region.
The compound may be contained in any appropriate amount in any suitable N \Mclbown\Cases\Patent\52000-52999\P52767.AU I\Spcis\Specificaion fileddoc 14o00 carrier substance, and is generally present in an amount of 1-95% by weight of Sthe total weight of the composition. The composition may be provided in a dosage form that is suitable for the oral, parenteral intravenously, Sintramuscularly), rectal, cutaneous, nasal, vaginal, inhalant, skin (patch), or ocular 5 administration route. Thus, the composition may be in the form of, tablets, capsules, pills, powders, granulates, suspensions, emulsions, solutions, gels including hydrogels, pastes, ointments, creams, plasters, drenches, osmotic delivery devices, suppositories, enemas, injectables, implants, sprays, or aerosols.
0, The pharmaceutical compositions may be formulated according to conventional pharmaceutical practice (see, Remington: The Science and Practice of Pharmacy (20th ed. A.R. Gennaro, Lippincott Williams Wilkins, 2000 and Encyclopedia of Pharmaceutical Technology, eds. J. Swarbrick and J. C. Boylan, 1988-1999, Marcel Dekker, New York).
Pharmaceutical compositions according to the invention may be formulated to release the active compound substantially immediately upon administration or at any predetermined time or time period after administration.
The latter types of compositions are generally known as controlled release formulations, which include formulations that create a substantially constant concentration of the drug within the body over an extended period of time; (ii) formulations that after a predetermined lag time create a substantially constant concentration of the drug within the body over an extended period of time; (iii) formulations that sustain drug action during a predetermined time period by maintaining a relatively, constant, effective drug level in the body with concomitant minimization of undesirable side effects associated with fluctuations in the plasma level of the active drug substance (sawtooth kinetic pattern); (iv) formulations that localize drug action by, spatial placement of a controlled release composition adjacent to or in the diseased tissue or organ; and (v) formulations that target drug action by using carriers or chemical derivatives to deliver the drug to a particular target cell type.

Sformulation is especially preferred in cases in which the compound, either alone t or in combination, has a narrow therapeutic index the difference between Sthe plasma concentration leading to harmful side effects or toxic reactions and the N 5 plasma concentration leading to a therapeutic effect is small; in general, the therapeutic index, TI, is defined as the ratio of median lethal dose (LD50) to median effective dose (ED50)); (ii) a narrow absorption window in the gastro- Sintestinal tract; or (iii) a very short biological half-life so that frequent dosing 00 during a day is required in order to sustain the plasma level at a therapeutic level.
0 10 Any of a number of strategies can be pursued in order to obtain controlled release in which the rate of release outweighs the rate of metabolism of the compound in question. In one example, controlled release is obtained by appropriate selection of various formulation parameters and ingredients, including, various types of controlled release compositions and coatings.
Thus, the drug is formulated with appropriate excipients into a pharmaceutical composition that, upon administration, releases the drug in a controlled manner.
Examples include single or multiple unit tablet or capsule compositions, oil solutions, suspensions, emulsions, microcapsules, microspheres, nanoparticles, patches, and liposomes.
Solid dosage forms for oral use Formulations for oral use include tablets containing the active ingredient(s) in a mixture with non-toxic pharmaceutically acceptable excipients.
These excipients may be, for example, inert diluents or fillers sucrose, sorbitol, sugar, mannitol, microcrystalline cellulose, starches including potato starch, calcium carbonate, sodium chloride, lactose, calcium phosphate, calcium sulfate, or sodium phosphate); granulating and disintegrating agents cellulose derivatives including microcrystalline cellulose, starches including potato starch, croscarmellose sodium, alginates, or alginic acid); binding agents sucrose, glucose, sorbitol, acacia, alginic acid, sodium alginate, gelatin, starch, pregelatinized starch, microcrystalline cellulose, magnesium aluminum N \Mclbourn\Cases\Paienl\52000 52999\P52767 AU I \Spec&SSpcification fileddoc -16- 0 o silicate, carboxymethylcellulose sodium, methylcellulose, hydroxypropyl C methylcellulose, ethylcellulose, polyvinylpyrrolidone, or polyethylene glycol); and lubricating agents, glidants, and antiadhesives magnesium stearate, zinc Sstearate, stearic acid, silicas, hydrogenated vegetable oils, or talc). Other 5 pharmaceutically acceptable excipients can be colorants, flavoring agents, plasticizers, humectants, buffering agents, and the like.
The tablets may be uncoated or they may be coated by known techniques, optionally to delay disintegration and absorption in the gastrointestinal tract and 00 thereby providing a sustained action over a longer period. The coating may be adapted to release the active drug substance in a predetermined pattern in order to achieve a controlled release formulation) or it may be adapted not to release the active drug substance until after passage of the stomach (enteric coating). The coating may be a sugar coating, a film coating based on hydroxypropyl methylcellulose, methylcellulose, methyl hydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose, acrylate copolymers, polyethylene glycols and/or polyvinylpyrrolidone), or an enteric coating based on methacrylic acid copolymer, cellulose acetate phthalate, hydroxypropyl methylcellulose phthalate, hydroxypropyl methylcellulose acetate succinate, polyvinyl acetate phthalate, shellac, and/or ethylcellulose). Furthermore, a time delay material such as, glyceryl monostearate or glyceryl distearate may be employed.
The solid tablet compositions may include a coating adapted to protect the composition from unwanted chemical changes, chemical degradation prior to the release of the active drug substance). The coating may be applied on the solid dosage form in a similar manner as that described in Encyclopedia of Pharmaceutical Technology, supra.
The two drugs may be mixed together in the tablet, or may be partitioned.
In one example, the first drug is contained on the inside of the tablet, and the second drug is on the outside, such that a substantial portion of the second drug is released prior to the release of the first drug.

Controlled release percutaneous and topical compositions are several approaches for providing rate control over the release 0, and transdermal permeation of a drug, including: membrane-moderated systems, adhesive diffusion-controlled systems, matrix dispersion-type systems, and microreservoir systems. A controlled release percutaneous and/or topical composition may be obtained by using a suitable mixture of the above-mentioned approaches.
In a membrane-moderated system, the active drug is present in a reservoir which is totally encapsulated in a shallow compartment molded from a drugimpermeable laminate, such as a metallic plastic laminate, and a rate-controlling polymeric membrane such as a microporous or a non-porous polymeric membrane ethylene-vinyl acetate copolymer). The active compound is only released through the rate-controlling polymeric membrane. In the drug reservoir, the active drug substance may either be dispersed in a solid polymer matrix or suspended in a viscous liquid medium such as silicone fluid. On the external surface of the polymeric membrane, a thin layer of an adhesive polymer is applied to achieve an intimate contact of the transdermal system with the skin surface. The adhesive polymer is preferably a hypoallergenic polymer that is compatible with the active drug.
In an adhesive diffusion-controlled system, a reservoir of the active drug is formed by directly dispersing the active drug in an adhesive polymer and then spreading the adhesive containing the active drug onto a flat sheet of substantially drug-impermeable metallic plastic backing to form a thin drug reservoir layer.
A matrix dispersion-type system is characterized in that a reservoir of the active drug substance is formed by substantially homogeneously dispersing the active N eiclborn\Cases\Paen\S5200.5299952767AU, I\Specis\Specificaion fileddoc -23- 00 drug substance in a hydrophilic or lipophilic polymer matrix and then molding the drug-containing polymer into a disc with a substantially well-defined surface area and thickness. The adhesive polymer is spread along the circumference to form a Sstrip of adhesive around the disc.
r, 5 In a microreservoir system, the reservoir of the active substance is formed by first suspending the drug solids in an aqueous solution of water-soluble polymer, and then dispersing the drug suspension in a lipophilic polymer to form a plurality of microscopic spheres of drug reservoirs.
00 oO Dosages The dosage of each compound of the claimed combinations depends on several factors, including: the administration method, the condition to be treated, the severity of the condition, whether the condition is to be treated or prevented, and the age, weight, and health of the person to be treated. Additionally, pharmacogenomic (the effect of genotype on the pharmacokinetic, pharmacodynamic or efficacy profile of a therapeutic) information about a particular patient may affect dosage used.
As described above, the compound in question may be administered orally in the form of tablets, capsules, elixirs or syrups, or rectally in the form of suppositories. Parenteral administration of a compound is suitably performed, for example, in the form of saline solutions or with the compound incorporated into liposomes. In cases where the compound in itself is not sufficiently soluble to be dissolved, a solubilizer such as ethanol can be applied. Below, for illustrative purposes, the dosages for dipyridamole and fludrocortisone are described.
Routes of administration For oral, intramuscular, subcutaneous, topical, inhalation, rectal, vaginal and ophthalmic administration of the tetra-substituted pyrimidopyrimidine, the dosage is normally about 0.5-800 mg/day, preferably about 18-600 mg/day, and more preferably about 50-400 mg/day. Administration can be one to four times daily for one day to one year, and may even be for the life of the patient.

Dosages up to 3000 mg/day may be necessary.
The following examples are to illustrate the invention. They are not meant to limit the invention in any way.
Example 1: Preparation of pairwise compound mixed combination serial dilution matrix Stock solutions at 16 mg/ml of dipyridamole, and 1.6 mg/ml of fludrocortisone acetate (Sigma-Aldrich, St. Louis, MO; catalog numbers D9766 and F6127, respectively) were made in dimethylsulfoxide (DMSO). The dipyridamole master plates were made by adding 25 il of the concentrated stock solution to columns 3, 9, and 15 (rows C through N) of a polypropylene 384-well storage plate that had been pre-filled with 75 pl of anhydrous DMSO. Using a TomTec Quadra Plus liquid handler, the 25 pl of dipyridamole stock solution was serially diluted four times into the adjacent columns (columns 4-7, 10-13, 16-19).
The sixth column 14, and 20) did not receive any compound and served as a vehicle control. The fludrocortisone master plates were made by adding 25 pl of the concentrated stock solution to the appropriate wells (row C, columns 3-8; row C, columns 9-14; row C, columns 15-20; row I, columns 3-8; row I, columns 9- N \),clbourne\Cass\Paent\5200-52999\P52767 AU IMpeci5Specificalion ieddoc 00 14; row I, columns 15-20) of the appropriate master polypropylene 384-well O storage plate. These master plates had been pre-filled with 75 Ptl of anhydrous DMSO. Using the TomTec Quadra Plus liquid handler, the 25 pl was serially diluted four times in the adjacent rows (rows D-G, and The sixth row (H
O
C1 5 and N) did not receive any compound to serve as a vehicle control. Master plates were sealed and stored at -20 0 C until ready for use.
The final dipyridamole/fludrocortisone combination plates were generated Sby transferring 1 pl from each of the dipyridamole and fludrocortisone master 00 plates to a dilution plate containing 100 pl of media (RPMI; Gibco BRL, #11875- 085), 10% Fetal Bovine Serum (Gibco BRL, #25140-097), 2% Penicillin/Streptomycin (Gibco BRL, #15140-122)) using the TomTec Quadra Plus liquid handler. This dilution plate was then mixed and a 10 tl aliquot transferred to the final assay plate, which had been pre-filled with 40 pl/well RPMI media containing the appropriate stimulant to activate TNFa secretion (see below).
Example 2: Assay for TNFa suppressing activity by the combination of dipyridamole and fludrocortisone The compound dilution matrix was assayed using a TNFcx ELISA method.
Briefly, a 100 pjl suspension of diluted human white blood cells contained within each well of a polystyrene 384-well plate (NalgeNunc) was stimulated to secrete TNFa by treatment with a final concentration of 10 ng/ml phorbol 12-myristate 13-acetate (Sigma) and 750 ng/tl ionomycin (Sigma). Various concentrations of each test compound were added at the time of stimulation. After 16-18 hours of incubation at 37 0 C in a humidified incubator, the plate was centrifuged and the supernatant transferred to a white opaque polystyrene 384 well plate (NalgeNunc, Maxisorb) coated with an anti-TNF antibody (PharMingen, #18631D). After a two-hour incubation, the plate was washed (Tecan PowerWasher 384) with phosphate buffered saline (PBS) containing 0.1% Tween 20 (polyoxyethylene sorbitan monolaurate) and incubated for an additional one hour with another anti- N :\Mebournc\Cases\Paenl\S52000-52999\P52767AU I \SpcciS pcificaion filed doc -26- 00 TNF antibody that was biotin labeled (PharMingen, 18642D) and horseradish Speroxidase (HRP) coupled to strepavidin (PharMingen, #13047E). After the plate was washed with 0.1% Tween 20/PBS, the HRP substrate (which contains Sluminol, hydrogen peroxide, and an enhancer such as para-iodophenol) was added C 5 to each well and light intensity measured using a LJL Analyst luminometer.
Control wells contained a final concentration of 1 ig/ml cyclosporin A (Sigma).
Together, dipyridamole and fludrocortisone were able to suppress TNFu Ssecretion in blood stimulated with phorbol 12-myristate 13-acetate and 00 ionomycin. As seen in Tables 1 and 2, dipyridamole was able to enhance the potency of fludrocortisone by 60-fold. At a concentration of 947 nM, fludrocortisone alone inhibited TNFa secretion by 39%. Addition of 124 nM dipyridamole to a concentration of only 15 nM fludrocortisone resulted in the inhibition of TNFa secretion by 39% (Table Efficacy was maintained while reducing the total drug species by over 80%, from 947 nM to 163 nM. In the presence of 2 pM dipyridamole, 50% TNFa inhibition is achieved by only 4 nM fludrocortisone. This level of inhibition is not possible with fludrocortisone alone at concentrations that would be expected to cause serious mineralocorticoidinduced side effects. Dipyridamole enhancement of fludrocortisone activity was observed in a secondary screen (Table Again, a low dose of 495 nM dipyridamole enhanced the potency of fludrocortisone by over 135 fold.
Specifically, 947 nM fludrocortisone alone was required to achieve a 52% reduction of TNFa secretion.

The initial stock solution of dipyridamole was 16 mg/ml, and prednisolone was 1.6 mg/ml.
Example 4: Assay for TNFa suppressing activity by the combination of dipyridamole and prednisolone The compound dilution matrix of Example 3, was assayed using the TNFc ELISA method of Example 2. The results are shown in Table 3. Together, dipyridamole and prednisolone were able to suppress TNFa secretion in blood stimulated with phorbol 12-myristate 13-acetate and ionomycin to a greater extent than either compound alone. Specifically, dipyridamole greatly increased the N \AMelbourne\Cases\Paten\l\2000- 2999\P52767.Aj I\Spcci\Specificaion fIled doc -28- 0 potency of prednisolone. Prednisolone alone, at a concentration of 250 nM, can N suppress TNFa secretion by 38%. The same level of suppression can be Sachieved by only 1 nM prednisolone in combination with 2 pM dipyridamole.
This represents a shift in the potency of prednisolone of over 250-fold. Further, the addition of 2 pM dipyridamole to 250 nM prednisolone resulted in a supramaximal effect compared to prednisolone alone The combination of low doses of prednisolone and dipyridamole, therefore, results in Sthe inhibition TNFx to levels previously unattainable without a high risk of 00 glucocorticoid-induced side effects.
