This invention is in the field of the prevention and treatment of neoplasia. More specifically, this invention relates to the use of cyclooxygenase-2 inhibitors or derivatives thereof in preventing and treating neoplasia.

Background of the Invention 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 adverse effects, especially when long term therapy is involved.

NSAIDs 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 (COX-2)" or "prostaglandin G/H synthase II") provides a viable target of inhibition which more effectively reduces inflammation and produces fewer and less 2 drastic side effects.

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

Neoplastic disease states are serious and oftentimes life-threatening conditions. These neoplastic diseases, which are characterized by rapidly-proliferating cell growth, continue to be the subject of worldwide research 15 efforts directed toward the identification of therapeutic agents which are effective in the treatment thereof. Effective therapeutic agents prolong the survivability of the patient, inhibit the rapidly-proliferating cell growth associated with the neoplasm, or effect a regression of 20 the neoplasm. Research in this area is primarily focused toward identifying, agents which would be therapeutically effective in humans and other mammals.

Recently, the presence of COX-2 has been observed in 25 neoplastic disease. See Masanobu Oshima et al. (Cell, 87, 803-809 (1996); and Michelle Parret et al. (International Journal of Oncology, 10, 503-507 (1997).

[Pyrazol-l-yl]benzenesulfonamides have been described 30 ' 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 preventing colon cancer has been described in U.S. Patent No. 5,466,823. However, their use 3 5 for treating colon cancer or for treating or preventing other neoplasias has not been previously described.

The present invention is directed to the use of inhibitors of cyclooxygenase-2 for the treatment and prevention of neoplasias. Conjunctive treatment of a selective cyclooxygenase-2 inhibitor with other neoplastic 5 agents produces a synergistic effect or alternatively reduces the toxic side effects associated with chemotherapy by reducing the concentration of the side effect-causing agent needed for therapeutic efficacy.

Detailed Description of the Invention The present invention provides a method for treating or preventing a neoplasia that produces a prostaglandin in a subject in need of such treatment or prevention, the method comprises treating the subject with a therapeutically effective amount of a cyclooxygenase-2 inhibitor or derivative thereof.

The term ■ "treatment" includes partial or total inhibition of the neoplasia growth, spreading or .metastasis, as well as partial or total destruction of the neoplasia cells.

The term "prevention" includes either preventing the onset of clinically evident neoplasia altogether or preventing the onset of a preclinically evident stage of neoplasia in individuals at risk. Also intended to be encompassed by this definition is the prevention of initiation for malignant cells or to arrest or reverse the progression of premalignant cells to malignant cells. This includes prophylactic treatment of those at risk of developing the neoplasia.

The phrase "therapeutically-effective" is intended to qualify the amount of each agent which will achieve the goal of improvement, in disease severity and the frequency of incidence over treatment of each agent by itself, while 4 avoiding adverse side effects typically associated with alternative therapies.

The term "subject" for purposes of treatment includes 5 any human or mammal subject who has any one of the known neoplasias, and preferably is a human subject. For methods of prevention, the subject is any human or animal subject, and preferably is a human subject who is at risk for obtaining an epithelium cell-derived neoplasia. The 10 subject may be at risk due to exposure to carcinogenic agents, being genetically predisposed to have the neoplasia, and the like.

The term "neoplasia" includes neoplasia that produce 15 prostaglandins or express a cyclooxygenase, including both benign and cancerous tumors, growths and polyps. ■ In the method above, the neoplasia that produce prostaglandins include brain cancer, bone cancer, 20 epithelial cell-derived neoplasia (epithelial carcinoma) such as basal cell carcinoma, adenocarcinoma, gastrointestinal cancer such as lip cancer, mouth cancer, esophogeal cancer, small bowel cancer and stomach cancer, colon cancer, liver cancer, bladder cancer, pancreas 25 cancer, ovary cancer, cervical cancer, lung cancer, breast cancer and skin cancer, such as squamus cell and basal cell cancers, prostate cancer, renal cell carcinoma, and other known cancers that effect epithelial cells throughout the body. Preferably, neoplasia is selected 3 0 from gastrointestinal cancer, liver cancer, bladder cancer, pancreas cancer, ovary cancer, prostate cancer, cervicai cancer, lung cancer, breast cancer and skin cancer, such as squamus cell and basal cell cancers. The COX-2 inhibitors can also be used to treat the fibrosis 35 which occurs with radiation therapy. The method can be used to treat subjects having adenomatous polyps, including those with familial adenomatous polyposis (FAP).

Additionally, the method can be used to prevent polyps from forming in patients at risk of FAP.

Inhibitors of the eye 1 ©oxygenase pathway in the 5 metabolism of arachidonic acid used in the prevention and treatment of epithelial cell derived neoplasias may inhibit enzyme activity through a variety of mechanisms. By the way of example, the inhibitors used in the methods described herein may 10 block the enzyme activity directly by acting as a substrate for the enzyme. The use of cyclooxygenasse-2 selective inhibitors is highly advantageous in that they minimize the gastric side effects that can occur with non-selective NSAID's, especially where prolonged prophylactic treatment is expected.

The term "cyclooxygenase-2 inhibitor" denotes a compound able to inhibit cyciooxygenase-2 without significant inhibition of cyclooxygenase-1.

Preferably, it includes compounds which have a cyclooxygenase-2 IC50 of less than about 0.2 uM# and also have a selectivity ratio of cyclooxygenase-2 inhibition over cyclooxygenase-1 inhibition of at least 50, and more preferably of at least 100. Even more preferably, the compounds have a cyclooxygenase-1 IC50 of greater than about 1 uM, and more preferably of greater than 10 yM.

Biological Evaluation The efficacy of cyclooxygenase-2 inhibitors as antineoplasia agents was determined in the following models: Murine Lewis lung Carcinoma Model.

Lewis lung carcinomas were implanted sub-cutaneously into the foot pad of male C57BL/6 mice. The mice were subsequently treated with 4-[5-(4-chlorophenyl)-3-(difluoromethyl)-lH-pyrazol-l-yl]benzenesulfonamide. The drug was supplied in the drinking water at 6 mg/kg/day. Also a non-selective COX-l/COX-2 inhibitor indomethacin was tested in this model; The drug was supplied in the drinking water at the maximum tolerated dose of 2 mg/kg/day. A total of 10 mice/compound were tested.

Tumor volume was determined twice a week using a plethysmometer. The efficacy of these compounds on tumor growth was measured at day 32 after cancer cell injection, as indicated in Table 1. The % inhibition value is calculated by calculating the difference in tumor size compared with the control group.

Table 1.

Tumor Volume (Day 32) Treatment % Inhibition Vehicle/control 0.00 COX-2 inhibitor 70.86 Indomethacin 62.90 Human prostate cancer cell tumors Two human prostate cancer cell lines (PC-3 and LNCaP) were obtained (ATCC) to determine the efficacy of cyclooxygenase-2 inhibitors to inhibit tumor growth in a therapeutic model. In addition, the LNCaP cell line secretes prostate serum antigen (PSA) When grown in nude mice.

PC-3 PC-3 cells (10s cells/0.2 ml 9f 30% matrigel) in RPMI 1640 medium was injected on the back of nude mice. At day 28, a COX-2 inhibitor 4-[5-(4-chlorophenyl)-3-(difluoromethyl)-lH-pyrazol-l-yl]benzenesulfonamide (20 mg/kg/day in water) was administered. After 45 days, PGE2 21 and TXB2 were measured. The COX-2 inhibitor inhibited tumor growth by 55%. PGE2 and TXB2 levels were reduced by 80-90% in the animals treated with the COX-2 inhibitor.

LNCaP Similar to the results in PC-3, a COX-2 inhibitor 4-[5-(4-chlorophenyl)-3-(difluoromethyi)-lH-pyrazol-1-yl]benzenesulfonamide at a dose equivalent to 6 mg/kg/day in the drinking water inhibited the growth of the tumor by 55% at day 58. PSA level was reduced to approximately 50% as judged by western blotting.

All cells can be grown in RPMI-1640, supplemented with 5% fetal bovine serum-(FBS), penicillin and streptomycin (Gibco, Grand Island, NY) , and be maintained in a 5% C02atmosphere at 37°C. All cell lines are free of mycoplasma contamination.

Growth studies: A modification (Promega CellTiter 96®, Promega Madison, WI) of the semiautomated colorimetric assay, MTT [Nakanishi, et al. Exper. Cell Biol.,' 56, 74-85 (1988)], which quantitates cell numbers based on reduction of a tetrazolium compound by tumor cells as determined by a spectrophotometer (540 nm) is used. All assays are performed in RPMI-1640 media supplemented with transfertin ~10 g/ml, insulin ~5 g/ml and selenium (Sigma Chemicals, St. Louis, MO). Seeding 22 densities are ~2xl04 celis/well, and cells are grown for 5 days. Each experiment is reported as mean optical density corrected for background + /- standard deviation. The cyclooxygenasse-2 inhibitors should be active, at a dose 5 of 20 mg/kg, in inhibiting growth of the cancerous cell lines.

Preparations for injections may also be formulated by suspending or emulsifying the compounds in non-aqueous solvent, such as vegetable oil, synthetic aliphatic acid glycerides^ esters of. higher aliphatic acids or propylene glycol.

FoiTnulations for topical use include known gels, creams, oils, and the like. For aerosol delivery, the 31 compounds may be formulated with known aerosol exipients* such as saline, and administered using commercially available nebulizers. Formulation in a fatty acid soutce may be used to enhance biocompatibility. Aerosol delivery is the preferred method of delivery for epithelial neoplasias of the lung for prevention application.

For rectal administration, the active ingredient may be formulated into suppositories using bases which are solid at room temperature and melt or dissolve at body temperature. Commonly used bases include cocoa butter, glycerinated gelatin, hydrogenated vegetable oil, polyethylene glycols of various molecular weights, and fatty esters of polyethylene stearate.

The dosage form and amount can be readily established by reference to known neoplasia treatment or prophylactic regiments. The amount of therapeutically active compound that is administered and-the dosage regimen for treating a disease condition with the compounds and/or compositions of this invention depends on a variety of factors, including the age, weight, sex and medical condition of the subject, the severity of the disease, the route and frequency of administration, and the particular compound employed, the location of the neoplasia, as well as the pharmacokinetic properties of the individual treated, and thus may vary widely. The dosage will generally be lower if the compounds are administered locally rather than systemically, and for prevention rather than for treatment. Such treatments may be administered as often as necessary and for the period of time judged necessary by the treating physician. One of skill in the art will appreciate that the. dosage regime or therapeutically effective amount of the inhibitor to be administrated may need to be optimized for each individual. The pharmaceutical compositions may contain active ingredient in the range of about 0.1 to 2000 mg, preferably in the
