60/294,077 filed on May 29,2001, which is hereby incorporated by reference in its entirety Field of the Invention The present invention provides a method for the treatment or prevention of cardiovascular disease. More particularly, the invention is directed toward a method for the treatment or prevention of restenosis.

Background of the Invention Cardiovascular disease is the number one cause of mortality in the world. Many cardiac disorders (e. g., coronary artery disease [CAD], systemic hypertension, bicuspid aortic valve, hypertrophic cardiomyopathy, mitral valve prolapse) have a heritable basis.

Although the precise pathogenesis of CAD is unclear, the risk factors are well known: high blood levels of low density lipoprotein cholesterol (LDL-C) and lipoprotein a, low blood levels of high density lipoprotein cholesterol (HDL-C) and serum vitamin E, and poor physical fitness. High blood levels of triglycerides and insulin reflecting insulin resistance may be risk factors, but the data are less clear. CAD risk is increased by tobacco use; diets high in fat and calories and low in phytochemicals (found in fruits and vegetables), fiber, and vitamins E and C, or diets with relatively low levels of omega-3 polyunsaturated fatty acids (PUFAs); poor stress management; and inactivity. Several systemic diseases (e. g., hypertension, diabetes, hypothyroidism) are also associated with increased CAD risk.

Iscehmic heart disease due to coronary artery stenosis is a significant cause of morbidity and mortality in the United States. Reversal and control of coronary artery disease was originally accomplished through the use of coronary artery bypass graft (CABG) techniques developed in the 1960s. In the 1970s and 1980s, an additional treatment method became available with the development of percutaneous transluminal coronary angioplasty (PTCA). Over 400,000 angioplasties are now performed each year in the United States alone.

Although successful in treating coronary artery disease, a recurring problem with angioplasty has been the occurrence of restenosis. Restenosis has been called the "Achilles'heel"of PTCA. Studies have shown that without intervention, 30%-60% of angioplasties will restenose. The mechanism contributing to restenosis after PTCA include 1) elastic recoil; 2) mural thrombosis with thrombus organization; 3) smooth muscle cell migration, proliferation, and synthesis of extracellular matrix; and 4) late vessel cross-sectional constriction or shrinkage (negative remodeling).

The first component, recoil and remodeling, involves the mechanical collapse and constriction of the treated vessel and does not seem to progress much beyond the first day of treatment. The second component, thrombosis, involves a complex interaction among many hemostatic factors that are triggered following vascular injury.

This component has been implicated as a major early mechanism underlying restenosis.

The third component involves intimal hyperplasia, which is the proliferative response to injury and consists largely of smooth muscle cell and matrix formation. This process begins within a few days after vessel injury and continues for weeks to months until equilibrium between the vessel wall and lumen is achieved. When excessive, intimal hyperplasia can result in severe luminal renarrowing. The fourth component, negative remodeling, appears to be analogous to wound contracture and may be related to contraction of the periadventitual fibroelastic scar.

The rate of restenosis dropped significantly with the development in the 1990s of endovascular stenting techniques, which addressed the problem of mechanical collapse and contraction. The use of stents has been shown to decrease the incidence of restenosis by approximately 30%. Stents, however, do not address the problem of intimal hyperplasia and may even exacerbate the problem by causing local inflammation and damage to the intimal wall or myointimal junction. Restenosis is especially a problem in situations involving small vessels, ostial lesions, complex long and bifurcating lesions, vein grafts, and diffuse in-stent restenosis.

Recently the local application of radiation or brachytherapy has been used to prevent restenosis. The use of radiation to prevent restenosis is derived from the concept that restenosis is a proliferative wound healing process and proliferating cells are sensitive to low dose radiation. It is well known in the art that ionizing radiation is a potent anti-proliferative agent for both malignant and benign disorders and the use of radiation to modify the wound healing response has been well documented.

Radiation can be delivered over a sustained period using implantable devices such as stents containing radioactive isotopes or can be delivered transiently by insertion of a radioactive device at the site of angioplasty for a time sufficient to provide an anti- proliferative dose of radiation. Numerous implantable devices to prevent restenosis are known in the art. Examples include U. S. Patents 5,871,437 and 6,159,142 that disclose a stent coated with a biodegradable coating containing a radioactive source; U. S. Patent 5,919,126, which discloses a stent coated with a radiopaque material containing a beta- emitting radioisotope; U. S. Patent 6, 179,789, which discloses a stent coated with a biocompatible material having a radioactive material dispersed therein; U. S. Patent 6,187,037, which discloses a metal stent containing stable radioactive isotopes with a half-life of less than two months; U. S. Patent 6,196,963, which discloses a temporarily implantable brachytherapy device; and U. S. Patent 6,210,313, which discloses an implantable device coated with a chelator selected for its bonding affinity to a particular radioisotope.

Transient administration of anti-proliferative radiation is typically accomplished by insertion into the coronary artery of a catheter, ribbon or other such device for a time adequate to deliver a dose of radiation sufficient to prevent intimal hyperplasia. Examples of devices for the transient delivery of radiation include U. S.

Patent 5,662,580; U. S. Patent 6,196,996; and U. S. Patent 6,200,256.

Although the previously discussed examples have involved the use of beta or gamma radiation, ultraviolet ("W") radiation can also be used. Examples of the application of UV radiation include U. S. Patent 5,053,033; U. S. Patent 5,116,864; U. S.

Patent 5,620,438; and U. S. Patent 6,200,307.

Restenosis is also thought to involve an inflammatory component. Damage to the arterial wall during arterial procedures such as angioplasty and arterial grafting, leads to the release of proinflammatory compounds such as cytokines from macrophages. It has been hypothesized that the ability of radiation to prevent restenosis is due, in part, to the effect of the radiation on inflammatory cells. For example, Rubin et al., (Intl. J.

Radiat Oncol. Biol. Phys., 40: 929-941,1998) reported a reduction in monocytes and adventitial macrophages after irradiation of balloon injured rat carotids, corresponding to decreased intimal hyperplasia.

Because of the inflammatory component of restenosis, several anti- inflammatories have been used. For example, Rab et al. (J. Am Coll. Cardiol., 18: 1524-

1528,1991) administered glucocorticoids with or without colchicine to patients receiving stents and reported an increase in the incidence of coronary artery aneurysms. Valero et al. (J. Cardiovasc. Pharmacol., 31: 513-519,1998), introduced hydrocortisone-loaded microspheres into the arterial walls of rabbits during angioplasty. They reported that hydrocortisone-loaded microspheres were associated with a significant reduction in intimal hyperplasia. Strecker et al. (Cardiovasc. Intervent. Radiol., 21: 487-496,1998), reported that dexamethasone-coated stents showed reduced neointimal hyperplasia in dogs when compared to non-coated stents. In contrast, Lee et al. (Am. Heart J., 138: 304, 1999), reported that single dose pretreatment with intravenous methylpridnisolone before coronary stenting had no effect on the change in minimal lumen diameter at 6 months.

Non-steroidal anti inflammatories have also been used to decrease restenosis.

Chaldakov (Med. Hypotheses, 37: 74-75,1992) proposed the use of the anti- inflammatories sulfasalazine, griseofulvin and colchicine to lessen coronary restenosis after angioplasty. Huang et al. (Eur. J. Pharmacol., 221: 381-384,1992), reported that curcumin, an anti-inflammatory agent from Curcuma loizga, reduced proliferation of vascular smooth muscle cells in vitro. Ishiwata et al. (J. Am. Coll. Cardio. 35: 1331- 1337,2000) reported that orally administered N- (3, 4-dimethoxycinnamoyl) anthranilic acid (tranilast) resulted in a lower rate of restenosis in stent implanted pig arteries. In contrast, Grinstead et al. (Coron. Artery Dis. 4: 277-281,1993) found that oral administration of aniprilose hydrochloride, a synthetic carbohydrate with anti- inflammatory and antiproliferative properties did not prevent coronary intimal proliferation in the swine model of restenosis. None of these references disclose or suggest the use of radiation in combination with anti-inflammatories to prevent restenosis.

Prostaglandins play a major role in the inflammation process and the inhibition of prostaglandin production, especially production of PGG2, PGH2 and PGE2, has been a common target of anti-inflammatory drug discovery. However, common non-steroidal anti-inflammatory drugs (NSAID's) that are active in reducing the prostaglandin-induced pain and swelling associated with the inflammation process are also active in affecting other prostaglandin-regulated processes not associated with the inflammation process.

Thus, use of high doses of most common NSAID's can produce severe side effects, including life-threatening ulcers that limit their therapeutic potential. An alternative to NSAID's is the use of corticosteroids, which also produce severe adverse effects,

especially when long-term therapy is involved and whose usefulness in preventing restenosis has been questioned (Kong, Am. Heart J., 138 : 3-4,1999).

NSAID's have been found to prevent the production of prostaglandins by inhibiting enzymes in the human arachidonic acid/prostaglandin pathway, including the enzyme cyclooxygenase (COX). The recent discovery of an inducible enzyme associated with inflammation (named"cyclooxygenase-2"or "prostaglandin G/H synthase II") provides a viable target of inhibition, which more effectively reduces inflammation and produces fewer and less drastic side effects.

Compounds that selectively inhibit cyclooxygenase-2 have been described in U. S. patents 5,380,738; 5,344,991; 5,393,790; 5,434,178; 5,474,995; 5,510,368 and WO documents W096/06840, W096/03388, W096/03387, W096/19469, W096/25405, W095/15316, W094/15932, W094/27980, W095/00501, W094/13635, W094/20480, and W094/26731.

[Pyrazol-l-yl] benzenesulfonamides have been described as inhibitors of cyclooxygenase-2 and have shown promise in the treatment of inflammation, arthritis, and pain, with minimal side effects in pre-clinical and clinical trials. Their use for treating inflammation in vascular disease has been described in U. S. Patent No.

5,466,823. Their use for preventing cardiovascular-related diseases has been described in co-pending U. S. application 09/402,634.

Description of the Preferred Embodiments It has been discovered that inhibition or prevention of cardiovascular disease, and in particular vascular restenosis, is provided by a combination therapy comprising administering to a subject a cyclooxygenase-2 selective inhibitor along with a dose of radiation. Restenosis, as detailed above, occurs due to the interaction of numerous biological events, including a wound healing response and an inflammatory response, that are triggered as a result of procedures such as coronary angioplasty. It is known in the art that ionizing radiation ameliorates the wound healing response. Further, it is also known in the art that cyclooxygenase-2 selective inhibitors are potent anti-inflammatory agents. The presently described combination therapy is beneficial for the treatment of cardiovascular disease, therefore, without being bound to any particular theory, because cyclooxygenase-2 selective inhibitors and radiation each attenuate independent biological events that are known to cause restenosis.

Thus, the coupling of a cyclooxygenase-2 selective inhibitor and radiation provides a synergistic therapy for the treatment of cardiovascular disease.

Moreover, the use of cyclooxygenase-2 selective inhibitors is highly advantageous in that it minimizes the gastric side effects that can occur with non-selective NSAID's, especially where prolonged treatment is expected.

The present method, accordingly, can be used for the prevention or inhibition of restenosis following vascular intervention such as angioplasty, grafting, stent placement, endarterectomy, atherectomy (including rotational, directional and extraction atherectomy), or excimer laser therapy of coronary stenosis. In one embodiment, the method can be used for preventing or inhibiting restenosis following angioplasty and in

particular coronary artery angioplasty (percutaneous transluminal coronary angioplasty or PTCA). In another embodiment, the method can be used for preventing or inhibiting restenosis following vascular grafting and in particular, coronary artery bypass grafting (CABG).

The compounds utilized in the methods of the present invention may be in the form of free bases or pharmaceutically acceptable acid addition salts thereof. The term "pharmaceutically-acceptable salts"embraces salts commonly used to form alkali metal salts and to form addition salts of free acids or free bases. The nature of the salt may vary, provided that it is pharmaceutically-acceptable. Suitable pharmaceutically- acceptable acid addition salts of compounds for use in the present methods may be prepared from an inorganic acid or from an organic acid. Examples of such inorganic acids are hydrochloric, hydrobromic, hydroiodic, nitric, carbonic, sulfuric and phosphoric acid. Appropriate organic acids may be selected from aliphatic, cycloaliphatic, aromatic, araliphatic, heterocyclic, carboxylic and sulfonic classes of

organic acids, examples of which are formic, acetic, propionic, succinic, glycolic, gluconic, lactic, malic, tartaric, citric, ascorbic, glucuronic, maleic, fumaric, pyruvic, aspartic, glutamic, benzoic, anthranilic, mesylic, 4-hydroxybenzoic, phenylacetic, mandelic, embonic (pamoic), methanesulfonic, ethanesulfonic, benzenesulfonic, pantothenic, 2-hydroxyethanesulfonic, toluenesulfonic, sulfanilic, cyclohexylaminosulfonic, stearic, algenic, ß-hydroxybutyric, salicylic, galactaric and galacturonic acid. Suitable pharmaceutically-acceptable base addition salts of compounds of use in the present methods include metallic salts made from aluminum, calcium, lithium, magnesium, potassium, sodium and zinc or organic salts made from N, N'-dibenzylethylenediamine, chloroprocaine, choline, diethanolamine, ethylenediamine, meglumine (N-methylglucamine) and procaine. All of these salts may be prepared by conventional means from the corresponding compound by reacting, for example, the appropriate acid or base with the compound of any Formula set forth herein.

The cyclooxygenase-2 selective inhibitors useful in the practice of the present methods can be formulated into pharmaceutical compositions and administered by any means that will deliver a therapeutically effective dose. Such compositions can be administered orally, parenterally, by inhalation spray, rectally, intradermally, transdermally, or topically in dosage unit formulations containing conventional nontoxic pharmaceutically acceptable carriers, adjuvants, and vehicles as desired. Topical administration may also involve the use of transdermal administration such as transdermal patches or iontophoresis devices. The term parenteral as used herein includes subcutaneous, intravenous, intramuscular, or intrasternal injection, or infusion techniques. Formulation of drugs is discussed in, for example, Hoover, John E., Renaington's Phcrrriaceutical Sciences, Mack Publishing Co., Easton, Pennsylvania (1975), and Liberman, H. A. and Lachman, L., Eds., Pharmaceutical Dosage Forms, Marcel Decker, New York, N. Y. (1980).

Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions, can be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a nontoxic parenterally acceptable diluent or solvent. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, and isotonic sodium chloride solution. In addition, sterile, fixed oils

are conventionally employed as a solvent or suspending medium. For this purpose, any bland fixed oil may be employed, including synthetic mono-or diglycerides. In addition, fatty acids such as oleic acid are useful in the preparation of injectables. Dimethyl acetamide, surfactants including ionic and non-ionic detergents, and polyethylene glycols can be used. Mixtures of solvents and wetting agents such as those discussed above are also useful.

Suppositories for rectal administration of the compounds discussed herein can be prepared by mixing the active agent with a suitable non-irritating excipient such as cocoa butter, synthetic mono-, di-, or triglycerides, fatty acids, or polyethylene glycols which are solid at ordinary temperatures but liquid at the rectal temperature, and which will therefore melt in the rectum and release the drug.

Solid dosage forms for oral administration may include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the compounds are ordinarily combined with one or more adjuvants appropriate to the indicated route of administration. If administered per os, the compounds can be admixed with lactose, sucrose, starch powder, cellulose esters of alkanoic acids, cellulose alkyl esters, talc, stearic acid, magnesium stearate, magnesium oxide, sodium and calcium salts of phosphoric and sulfuric acids, gelatin, acacia gum, sodium alginate, polyvinylpyrrolidone, and/or polyvinyl alcohol, and then tableted or encapsulated for convenient administration. Such capsules or tablets can contain a controlled-release formulation as can be provided in a dispersion of active compound in hydroxypropylmethyl cellulose. In the case of capsules, tablets, and pills, the dosage forms can also comprise buffering agents such as sodium citrate, or magnesium or calcium carbonate or bicarbonate. Tablets and pills can additionally be prepared with enteric coatings.

For therapeutic purposes, formulations for parenteral administration can be in the form of aqueous or non-aqueous isotonic sterile injection solutions or suspensions.

These solutions and suspensions can be prepared from sterile powders or granules having one or more of the carriers or diluents mentioned for use in the formulations for oral administration. The compounds can be dissolved in water, polyethylene glycol, propylene glycol, ethanol, corn oil, cottonseed oil, peanut oil, sesame oil, benzyl alcohol, sodium chloride, and/or various buffers. Other adjuvants and modes of administration are well and widely known in the pharmaceutical art.

Liquid dosage forms for oral administration can include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, and elixirs containing inert diluents commonly used in the art, such as water. Such compositions can also comprise adjuvants, such as wetting agents, emulsifying and suspending agents, and sweetening, flavoring, and perfuming agents.

The amount of active ingredient that can be combined with the carrier materials to produce a single dosage form will vary depending upon the patient and the particular mode of administration. In general, the pharmaceutical compositions may contain a cyclooxygenase-2 selective inhibitor in the range of about 0.1 to 2000 mg, preferably in the range of about 0.5 to 500 mg and most preferably between about 1 and 200 mg. A daily dose of about 0.01 to 100 mg/kg body weight, preferably between about 0.1 and about 50 mg/kg body weight and most preferably from about 1 to 20 mg/kg body weight, may be appropriate. The daily dose can be administered in one to four doses per day.

In one embodiment, when the cyclooxygenase-2 selective inhibitor comprises rofecoxib, it is preferred that the amount used is within a range of from about 0.15 to about 1. 0 mg/day-kg, and even more preferably from about 0.18 to about 0.4 mg/day-kg.

In still another embodiment, when the cyclooxygenase-2 selective inhibitor comprises etoricoxib, it is preferred that the amount used is within a range of from about 0.5 to about 5 mg/day-kg, and even more preferably from about 0.8 to about 4 mg/day-kg.

Further, when the cyclooxygenase-2 selective inhibitor comprises celecoxib, it is preferred that the amount used is within a range of from about 1 to about 20 mg/day-kg, even more preferably from about 1.4 to about 8.6 mg/day-kg, and yet more preferably from about 2 to about 3 mg/day-kg.

When the cyclooxygenase-2 selective inhibitor comprises valdecoxib, it is preferred that the amount used is within a range of from about 0.1 to about 5 mg/day-kg, and even more preferably from about 0.8 to about 4 mg/day-kg.

In a further embodiment, when the cyclooxygenase-2 selective inhibitor comprises parecoxib, it is preferred that the amount used is within a range of from about 0.1 to about 5 mg/day-kg, and even more preferably from about 1 to about 3 mg/day-kg.

Those skilled in the art will appreciate that dosages may also be determined with guidance from Goodman & Goldman's The Pharmacological Basis of Therapeutics,

Ninth Edition (1996), Appendix II, pp. 1707-1711 and from Goodman & Goldman's The Pharmacological Basis of Therapeutics, Tenth Edition (2001), Appendix II, pp. 475-493.

In another embodiment, the pharmaceutical composition containing a suitable cyclooxygenase-2 selective inhibitor can also be administered locally at the site of vascular injury. For example and without limitation, a cyclooxygenase-2 selective inhibitor can be incorporated into a stent to be implanted into the vasculature. The stent can be coated with a degradable polymer into which the cyclooxygenase-2 selective inhibitor has been incorporated. As the polymer slowly degrades, it would release the cyclooxygenase-2 selective inhibitor into the area surrounding the stent. An example of a stent coated with a degradable polymer can be found in Strecker et al. (Cardiovasc.

Ititervent. Radio., 21: 487-496, 1998). Alternatively, local administration can be achieved by the use of microspheres that are implanted into the vascular wall at the time of vascular intervention. An example of the use of microspheres for administration of compounds to the vascular wall can be found in Valero et al. (J. Cardiovasc. Pharmacol.

31: 513-519,1998). Also included are catheter-based local delivery systems. Non- limiting examples of catheter-based local delivery systems include hydrophilic-coated catheter balloons that absorb the cyclooxygenase-2 selective inhibitor and then release it when pressed against the vessel wall, and fenestrated balloon catheters that use a high velocity jet to spray the cyclooxygenase-2 selective inhibitor against the vessel wall and thus embed it in the vessel wall.

The timing of the administration of the cyclooxygenase-2 selective inhibitor can also vary. For example, the cyclooxygenase-2 selective inhibitor can be administered beginning at a time prior to vascular intervention, at the time of vascular intervention, or at a time after vascular intervention. Administration can be by a single dose, or more preferably the cyclooxygenase-2 selective inhibitor is given over an extended period. In one embodiment, administration of the cyclooxygenase-2 selective inhibitor is commenced at one day prior to vascular intervention. In other embodiments, the cyclooxygenase-2 selective inhibitor is given beginning not more than 7, not more than 14, not more than 21, or not more that 30 days prior to the vascular intervention. It is preferred that administration of the cyclooxygenase-2 selective inhibitor extend for a period after the vascular intervention. In one embodiment, administration is continued for six months following intervention. In other embodiments, administration of the cyclooxygenase-2 selective inhibitor is continued for 1 week, 2 weeks, 1 month, 3

months, 9 months, or one year after vascular intervention. In one embodiment, administration of a cyclooxygenase-2 selective inhibitor is continued throughout the life of the subject following vascular intervention.

In the present method, the cyclooxygenase-2 selective inhibitor is administered in combination with radiation. The timing of the administration of the cyclooxygenase-2 selective inhibitor and radiation may vary from subject to subject. In one embodiment of the invention, the cyclooxygenase-2 selective inhibitor and radiation may be administered substantially simultaneously, meaning that both agents may be administered to the subject at approximately the same time. In one embodiment, for example, the cyclooxygenase-2 selective inhibitor or pharmaceutically acceptable salt or prodrug thereof is administered during a continuous period beginning on the same day as the beginning of the radiation therapy and extending to a period after the end of the radiation therapy. Alternatively, the cyclooxygenase-2 selective inhibitor and radiation may be administered sequentially, meaning that they are administered at separate times during separate treatments. In one embodiment, for example, the cyclooxygenase-2 selective inhibitor or a pharmaceutically acceptable salt or prodrug thereof is administered during a continuous period beginning prior to administration of the radiation and ending after administration of the radiation. Of course, it is also possible that the cyclooxygenase-2 selective inhibitor may be administered either more or less frequently than the radiation treatment. One skilled in the art can readily design suitable treatment regiments for a particular subject.

It will be apparent to those skilled in the art that it is possible, and perhaps desirable, to combine various times and methods of administration in the practice of the present invention. For example and without limitation, a subject may be administered a cyclooxygenase-2 selective inhibitor systemically for a period prior to the vascular procedure, followed by local administration by, for example, a cyclooxygenase-2 selective inhibitor releasing stent, followed by radiation treatment, followed by systemic administration after the release of the cyclooxygenase-2 selective inhibitor stops or has a significant decline.

The exact dose of radiation used will also vary with such factors as the tissue location, the species, age, sex and physical condition of the subject, the size of the tissue, and the type of vascular intervention involved. Exemplary radiation doses for coronary artery procedures are in the range of between about 3 Grays (Gy) to 60 Grays. In one

embodiment the dose is between about 8 Gy to about 35 Gy, in another embodiment between about 10 Gy to about 24 Gy and in still another embodiment between about between about 12 Gy to about 20 Gy.

Generally speaking, the radiation may be administered to any portion of a subject's body to the extent that its delivery to the location results in the desired degree of cell proliferation inhibition. Typically, the radiation is directed to a coronary blood vessel. In one embodiment, the coronary blood vessel is a coronary artery.

The radiation may be administered according to any method generally known in the art. In one embodiment, a platform is used to administer the radiation. The platform can be external, for example, a linear accelerator, or may be endovascular brachytherapy using, for example, a catheter or radioactive stent. One method of endovascular radiation therapy makes use of commercially available high dose rate after-loader systems.

Another method utilizes catheters and in particular balloon catheters. The catheters may contain a solid radiation source or a liquid source. In catheter-based systems, the catheter is advanced to the site to be irradiated and the balloon expanded to come in contact with the vessel walls. In an alternative embodiment, an implantable radiation source is used. Implantable radiation sources include, but are not limited to, radioactive stents, particles and microspheres. When ultra violet (UV) radiation is utilized, an optical fiber or other wave-guide can be used. Examples of methods for endovascular brachytherapy can be found in Massullo et al. (into. J. Radiation Oncol. Biol. P/ys., 36: 973-975,1996); Teirstein et al. (N. E. J. Med., 336: 1697-1703,1997); Valero et al. (J.

Cardiovasc. Phannacol., 31: 513-519; 1998); Ishiwata et al. (Jpn Heart J., 41 : 541-570, 2000); and U. S.

Examples of methods for the administration of UV radiation can be found in U. S. Patent numbers 5,116,864; 5,620,438; and 6,200,307.

Any type of radiation capable of inhibiting or preventing intimal hyperplasia can be used. In one embodiment, either electromagnetic or particle radiation can be used.

Examples of suitable types of radiation include alpha particles, beta particles, gamma rays, X-rays and ultra violet radiation. One preferred form of X-rays is"soft X-rays"or Grenz rays. These X-rays are of a longer wavelength and thus less penetrating than those conventionally used in radiotherapy.

Numerous sources of radiation can also be used including antimony-120, antimony-127, astatine-211, barium-128, barium-131, barium-140, bromine-80m, cadmium-115, cerium-134, cerium-141, cerium-143, cobalt-55, copper-64, copper-67, dysprosium-166, erbium-169, erbium-172, holmium-166, gadolinium-159, gallium-166, gallium-68, germanium-71, gold-198, gold-199, iodine-124, iodine-125, iodine-131, iridium-192, iridium-194, lanthanum-140, lutetium-172, lutetium-177, neodymium-140, nickel-66, niobium-95, osmium-191, palladium-100, palladium-103, phosphorus-32, phosphorus-33, platinum-188, platinum-191, platinum-193m, platinum-195m, platinum- 197, praseodymium-143, rhenium-186, rhenium-188, rhodium-99, rhodium-lOlm, rhodium 103m, rhodium-105, rubidium-82, ruthenium-103, samarium-153, scandium-47, scandium-48, silver-Ill, strontium-82, strontium-89, strontium-90, tantalum-177, tantalum-183, technetium-99m, tellurium-132, tellurium-118, terbium-153, terbium-156, thallium-201, thallium-204, thulium-170, thulium-172, tin-117m, tin-121, titanium-45, tungsten-178, vanadium-48, xenon-133, ytterbium-166, ytterbium-169, ytterbium-175, yttrium-87, yttrium-90, yttrium-91, zinc-72, and zirconium-89. Commonly used sources of radiation can be found in Table 3. As will be apparent to those skilled in the art, sources of radiation can be combined as, for example, a combination of strontium-90 and yttrium-90 (90SR/90Y) Table 4 Commonly Used Radiation Sources for Vascular Brachytherapy ISOTOPE EMISSION MAX.

In one embodiment, the method will further involve the administration of an antithrombotic agent and/or a platelet aggregation inhibitor. The administration of the antithrombotic agent or platelet aggregation inhibitor will typically begin prior to the vascular intervention and will extend for a period afterward, often the life of the subject.

Protocols for the administration of antithrombotics and platelet aggregation inhibitors for use in vascular intervention and coronary artery intervention in particular is widely available.

In another embodiment, the methods will further comprise administration of a corticosteroid, preferably a glucocorticoid. Examples of suitable glucocorticoids include hydrocortisone, dexamethasone and methylpridnisolone.

Examples The following examples are intended to provide illustrations of the application of the present invention. The following examples are not intended to completely define or otherwise limit the scope of the invention.

Example 1 Animal Models for Restenosis Various animal models have been developed to study cardiovascular disease in general and restenosis in particular. Reviews of these models can be found in Herrman et al. (Drugs, 46: 18-52,1993) and Landzberg et al. (Prog. Cardiovasc. Dis., 39: 361-398, 1997). One of the most widely used models, is the balloon-injured swine restenosis model of Karas et al. (J. Am. Coll. Cardiol., 20: 467-474,1992). In this method, coronary anteriography is performed on anesthetized domestic swine using a guiding catheter introduced into the femoral artery. Coronary vessel diameter is estimated from the arteriograms using catheter diameter as a standard. In order to induce vascular injury, balloons typically used have a diameter approximately 20% to 30% greater than the baseline arterial diameter. If a stent is to be implanted, the balloon is normally inflated twice for 30 seconds and then the catheter is removed. If the vessel is to remain unstented, the balloon is usually inflated three times. The site of balloon inflation and/or stenting can be irradiated immediately before, during or after the angioplasty. Various doses of radiation can be used in order to determine the optimal dose. Typically, radiation doses will be in the range of between about 3 Grays to about 60 Grays, more

typically in the range of about 10 Grays to 24 Grays and even more typically in the range of about between 12 Grays to 20 Grays. The dose of radiation is administered using any suitable method. Often radiation is administered using the same catheter used to expand the vessel. If W radiation is used, an optical wave-guide is inserted through the femoral artery and area of expansion treated with UV light. Following the procedure, the cutdown wound used to introduce the catheter is repaired and the animal allowed to recover.

To test the effect of administration of cyclooxygenase-2 selective inhibitors in combination with radiation to prevent restenosis, cyclooxygenase-2 selective inhibitors are administered at various doses and at various times prior to and after vascular intervention. The exact range of doses tested will vary with the particular cyclooxygenase-2 selective inhibitor to be tested. Any suitable method of administration can be used, for example, animals can be administered the compound orally from one to four times a day. The time period of administration is also varied to determine the optimal duration of administration. Typically, administration of the cyclooxygenase-2 selective inhibitor will begin shortly before or at the time of the vascular intervention and extend for varying periods after. Administration of cyclooxygenase-2 selective inhibitor throughout the course of the study is contemplated. The exact length of time of the study will vary with the particular situation, but in general, it is anticipated that studies will last from between 1 to 6 months.

Example 2 Analysis of Effect of Combination Therapy on Restenosis At various times during the course of the study, the effect of the combination therapy on restenosis can be assessed. On method of assessment is by histological study.

At various times, animals from treatment and control groups are sacrificed and the treated vessels quickly removed and fixed. The control group consists of animals that underwent the vascular intervention but did not receive the combination of cyclooxygenase-2 selective inhibitor and radiation. Fixed vessels are then embedded in a suitable sectioning material, sectioned, stained and examined by either light or electron microscopy. Vessel sections can be examined for known parameters associated with restenosis such as the size of the vessel lumen and the number of smooth muscle cells present in the section.

Alternatively, the effects can be determined by the use of arteriography or intravascular ultrasound. These methods have the advantage in that individual animals can be followed during the course of the study and data from various time points compared. Animals are anesthetized and anteriography or intravascular ultrasound performed in the same method as for angioplasty and the images recorded. A contrast filled catheter can be used for a calibration standard. Images obtained are then matched for position within the cardiac cycle and the diameters of the lumens compared. It is possible, of course, to combine both histological and arteriographic or ultrasound analysis, by measuring vessel diameter by arteriography or ultrasound during the experimental period and then sacrificing the animal at the end of the study in order to conduct a histological examination.

Example 3 Rat Carrageenan Foot Pad Edema Test The anti-inflammatory properties of cyclooxygenase-2 selective inhibitors for use in the present methods can be determined by the rat carrageenan foot pad edema test. The carrageenan foot edema test is performed with materials, reagents and procedures essentially as described by Winter, et al., (Proc. Soc. Exp. Biol. Med., 111 : 544,1962). Male Sprague-Dawley rats are selected in each group so that the average body weight is as close as possible. Rats are fasted with free access to water for over sixteen hours prior to the test. The rats are dosed orally (1 mL) with compounds suspended in vehicle containing 0.5% methylcellulose and 0.025% surfactant, or with vehicle alone. One hour later, a subplantar injection of 0.1 mL of 1 % solution of carrageenan/sterile 0.9% saline is administered and the volume of the injected foot is measured with a displacement plethysmometer connected to a pressure transducer with a digital indicator. Three hours after the injection of the carrageenan, the volume of the foot is again measured. The average foot swelling in a group of drug-treated animals is compared with that of a group of placebo-treated animals and the percentage inhibition of edema is determined (Otterness and Bliven, Laboratory Models for Testing NSAIDs, in Noyz-steroidal Anti-Irzflammatory Drugs, (J. Lombardino, ed.

1985)).
