Description

FIELD OF THE INVENTION

[0002] The present invention relates to compositions and methods employing combinations of a 3-heteroaryl-2-indolinone compound and a cyclooxygenase-2 (COX-2) selective inhibitor for treatment of neoplasia.

BACKGROUND OF THE INVENTION

[0003] A neoplasm, or tumor, is an abnormal, unregulated, and disorganized proliferation of cell growth. A neoplasm is malignant, or cancerous, if it has properties of destructive growth, invasiveness and metastasis. Invasiveness refers to the local spread of a neoplasm by infiltration or destruction of surrounding tissue, typically breaking through the basal laminas that define the boundaries of the tissues, thereby often entering the body's circulatory system. Metastasis typically refers to the dissemination of tumor cells by lymphotics or blood vessels. Metastasis also refers to the migration of tumor cells by direct extension through serous cavities, or subarachnoid or other spaces. Through the process of metastasis, tumor cell migration to other areas of the body establishes neoplasms in areas away from the site of initial appearance.

[0004] Cancer is now the second leading cause of death in the United States where over 8,000,000 individuals have been diagnosed with some form of cancer. In 1995, cancer accounted for 23.3% of all deaths in the United States. (See U.S. Dept. of Health and Human Services, National Center for Health Statistics, Health United States 1996-97 and Injury Chartbook 117 (1997)).

[0005] Cancer is not fully understood on the molecular level. It is known that exposure of a cell to a carcinogen such as certain viruses, chemicals, or radiation, leads to DNA alteration that inactivates a “suppressive” gene or activates an “oncogene”. Suppressive genes are growth regulatory genes, which upon mutation, can no longer control cell growth. Oncogenes are initially normal genes (called protooncogenes) that by mutation or altered context of expression become transforming genes. The products of transforming genes cause inappropriate cell growth. More than twenty different normal cellular genes can become oncogenes by genetic alteration. Transformed cells differ from normal cells in many ways, including cell morphology, cell-to-cell interactions, membrane content, cytoskeletal structure, protein secretion, gene expression and mortality (transformed cells can grow indefinitely).

[0006] Cancer is now primarily treated with one or a combination of three types of therapies: surgery, radiation, and chemotherapy. Surgery involves the bulk removal of diseased tissue. While surgery is sometimes effective in removing tumors located at certain sites, for example, in the breast, colon, and skin, it cannot be used in the treatment of tumors located in other areas, such as the backbone, nor in the treatment of disseminated neoplastic conditions such as leukemia.

[0007] Chemotherapy involves the disruption of cell replication or cell metabolism. It is used most often in the treatment of breast, lung, and testicular cancer. The adverse effects of systemic chemotherapy used in the treatment of neoplastic disease are most feared by patients undergoing treatment for cancer. Of these adverse effects nausea and vomiting are the most common and severe side effects. Other adverse side effects include cytopenia, infection, cachexia, mucositis in patients receiving high doses of chemotherapy with bone marrow rescue or radiation therapy; alopecia (hair loss); cutaneous complications (see M. D. Abeloff, et al: Alopecia and Cutaneous Complications. P. 755-56. In Abeloff, M. D., Armitage, J. O., Lichter, A. S., and Niederhuber, J. E. (eds) Clinical Oncology. Churchill Livingston, New York, 1992, for cutaneous reactions to chemotherapy agents), such as pruritis, urticaria, and angioedema; neurological complications; pulmonary and cardiac complications in patients receiving radiation or chemotherapy; and reproductive and endocrine complications.

[0008] Chemotherapy-induced side effects significantly impact the quality of life of the patient and may dramatically influence patient compliance with treatment.

[0009] Additionally, adverse side effects associated with chemotherapeutic agents are generally the major dose-limiting toxicity (DLT) in the administration of these drugs. For example, mucositis, is a major dose limiting toxicity for several anticancer agents, including the antimetabolite cytotoxic agents 5-FU, methotrexate, and antitumor antibiotics, such as doxorubicin. Many of these chemotherapy-induced side effects are severe, may lead to hospitalization, or require treatment with analgesics for the treatment of pain.

[0010] The adverse side effects induced by chemotherapeutic agents and radiation therapy have become of major importance to the clinical management of cancer patients.

[0063] Compounds that selectively inhibit the cyclooxygenase-2 enzyme have been discovered. These compounds selectively inhibit the activity of COX-2 to a greater extent than the activity of Cox-1. The new COX-2-selective inhibitors are believed to offer advantages that include the capacity to prevent or reduce inflammation while avoiding harmful side effects associated with the inhibition of Cox-1. Thus, cyclooxygenase-2-selective inhibitors have shown great promise for use in therapies—especially in therapies that require extended administration, such as for pain and inflammation control for arthritis.

[0065] COX-2 inhibitors have also been described for the treatment of cancer (WO98/16227) and for the treatment of tumors (See, EP 927,555, and Rozic et al., Int. J. Cancer, 93(4):497-506 (2001)). Celecoxib®, a selective inhibitor of COX-2, exerted a potent inhibition of fibroblast growth factor-induced corneal angiogenesis in rats. (Masferrer et al., Proc. Am. Assoc.

Drug Targets, 2(1):79-106 (2001) suggest that COX-2 selective inhibitors could be used to prevent or treat cancer by affecting tumor viability, growth, and metastasis. Masferrer et al., in Ann. NY Acad. Sci., 889:84-86 (1999) describe COX-2 selective inhibitors as antiangiogenic agents with potential therapeutic utility in several types of cancers. The utility of COX-2 inhibition in clinical cancer prevention was described by Lynch, P. M., in Oncology, 15(3):21-26 (2001), and Watanabe et al., in Biofactors 2000, 12(1-4):129-133 (2000) described the potential of COX-2 selective inhibitors for chemopreventive agents against colon cancer.

[0066] Additionally, various combination therapies using COX-2 inhibitors with other selected combination regimens for the treatment of cancer have also been reported. See e.g., FR 27 71 005 (compositions containing a cyclooxygenase-2 inhibitor and N-methyl-d-aspartate (NMDA) antagonist used to treat cancer and other diseases); WO 99/18960 (combination comprising a cyclooxygenase-2 inhibitor and an induced nitric-oxide synthase inhibitor (iNOS) that can be used to treat colorectal and breast cancer); WO 99/13799 (combination of a cyclooxygenase-2 inhibitor and an opioid analgesic); WO 97/36497 (combination comprising a cyclooxygenase-2 inhibitor and a 5-lipoxygenase inhibitor useful in treating cancer); WO 97/29776 (composition comprising a cyclooxygenase-2 inhibitor in combination with a leukotriene B4 receptor antagonist and an immunosuppressive drug); WO 97/29775 (use of a cyclooxygenase-2 inhibitor in combination with a leukotriene A4 hydrolase inhibitor and an immunosuppressive drug); WO 97/29774 (combination of a cyclooxygenase-2 inhibitor and prostaglandin or antiulcer agent useful in treating cancer); WO 97/111701 (combination comprising of a cyclooxygenase-2 inhibitor and a leukotriene B receptor antagonist useful in treating colorectal cancer); WO 96/41645 (combination comprising a cyclooxygenase-2 inhibitor and leukotriene A hydrolase inhibitor); WO 96/03385 (3,4,-Di substituted pyrazole compounds given alone or in combination with NSAIDs, steroids, 5-LO inhibitors, LTB4 antagonists, or LTA4 hydrolase inhibitors for the treatment of cancer); WO 98/47890 (substituted benzopyran derivatives that may be used alone or in combination with other active principles); WO 00/38730 (method of using cyclooxygenase-2 inhibitor and one or more antineoplastic agents as a combination therapy in the treatment of neoplasia); Mann, M. et al, Gastroenterology, 120(7):1713-1719 (2001) (combination treatment with COX-2 and HER-2/neu inhibitors reduced colorectal carcinoma growth).

[0109] The 3-heteroaryl-2-indolinone compounds of the present invention include but are not limited to 3-[(3-Methylpyrrol-2-yl)methylene]-2-indolinone; 3-[(3,4-Dimethylpyrrol-2-yl)methylene]-2-indolinone; 3-[(2-Methylthien-5-yl)methylene]-2-indolinone; 3-[(3-Methylthien-2-yl)methylene]-2-indolinone; 3-{[4-(2-methoxycarbonylethyl)-3-methylpyrrol-5-yl)]methylene}2-indolinone; 3-[(4,5-Dimethyl-3-ethylpyrrol-2-yl)methylene]-2-indolinone; 3-[(5-Methylimidazol-2-yl)methylene]-2-indolinone; 5-Chloro-3-[(5-methylthien-2-yl)methylene]-2-indolinone; 3-[(3,5-Dimethylpyrrol-2-yl)methylene]-5-nitro-2-indolinone; 3-[(3-(2-carboxyethyl)4-methylpyrrol-5-yl)methylene]-2-indolinone; 5-Chloro-3-[(3,5-dimethylpyrrol-2-yl)methylene]-2-indolinone; and 3-[(2,4-Dimethylpyrrol-5-yl)methylene]-2-indolinone, and prodrugs thereof. See U.S. Pat. No. 5,792,783 for a detailed description of 3-heteroaryl-2-indolinone compounds.

[0110] In a preferred embodiment of the invention, the 3-heteroaryl-2-indolinone compound is 3-[(2,4-Dimethylpyrrol-5-yl)methylene]-2-indolinone (SU5416) or a prodrug thereof.

[0111] In another embodiment, the indolinone combined with the COX-2 inhibitor to treat, prevent or inhibit neoplasia is a pyrrole substituted 2-indolinone, or a pharmaceutically acceptable salt or produg thereof, which modulates the activity of protein kinases. Such indolinones, and methods of providing or preparing them, are fully described in pending U.S. patent application Ser. No. 09/322,297, which has been allowed, and International Publication No. WO 99/61422, which are incorporated herein by reference. In a preferred embodiment, the indolinone is 3-[3,5-dimethyl-4-(2-carboxyethyl)pyrrol-2-ylmethylidene]-2-indolinone(SU-6668).

[0112] The chemical formulae of 3-heteroaryl-2-indolinone compounds referred to herein may exhibit the phenomena of tautomerism or structural isomerism. For example, the compounds described herein may adopt a cis or trans conformation about the double bond connecting the S indolinone 3-substituent to the indolinone ring, or may be mixtures of cis and trans isomers. As the formulae drawing within this specification can only represent one possible tautomeric or structural isomeric form, it should be understood that the invention encompasses any tautomeric or structural isomeric form, or mixtures thereof, which possesses the ability to regulate, inhibit and/or modulate tyrosine kinase signal transduction or cell proliferation and is not limited to any one tautomeric or structural isomeric form utilized within the formulae drawing.

[0113] In addition to the above-described compounds and their pharmaceutically acceptable salts, the indolinones of the invention include, where applicable, solvated as well as unsolvated forms of the compounds (e.g. hydrated forms) having the ability to regulate and/or modulate cell proliferation.

[0114] The 3-heteroaryl-2-indolinone compounds described herein may be prepared by any process known to be applicable to the preparation of chemically-related compounds. Suitable processes are illustrated in the examples. Necessary starting materials may be obtained by standard procedures of organic chemistry. An individual compound's relevant activity and efficacy as an agent to affect receptor tyrosine kinase mediated signal transduction may be determined using available techniques. Preferentially, a compound is subjected to a series of screens to determine the compound's ability to modulate, regulate and/or inhibit cell proliferation. These screens, in the order in which they are conducted, include biochemical assays, cell growth assays and in vivo experiments.

[0115] Preferably, a 3-heteroaryl-2-indolinone compound or prodrug thereof is administered in combination with a COX-2 selective inhibitor or prodrug thereof at a low dose, that is, at a dose lower than has been conventionally used in clinical situations for each of the individual components administered alone.

[0116] A benefit of lowering the dose of the compounds, compositions, agents and therapies of the present invention administered to a subject includes a decrease in the incidence of adverse effects associated with higher dosages. For example, by lowering the dosage of a chemotherapeutic agent such as Sugen 5416, a reduction in the frequency and the severity of side effects will result when compared to that observed at higher dosages. Similar benefits are contemplated for use of other 3-heteroaryl-2-indolinone compounds described herein in combination with COX-2 selective inhibitors.

[0117] By lowering the incidence of adverse effects, an improvement in the quality of life of a patient undergoing treatment is contemplated. Further benefits of lowering the incidence of adverse effects include an improvement in patient compliance, a reduction in the number of hospitalizations needed for the treatment of adverse effects, and a reduction in the administration of analgesic agents needed to treat pain associated with the adverse effects.

[0118] The combinations of COX-2 selective inhibitors and 3-heteroaryl-2-indolinone compounds described herein are useful for treating disorders related to unregulated tyrosine kinase signal transduction, including cell proliferative disorders, fibrotic disorders and metabolic disorders. The ability to use 3-heteroaryl-2-indolinones to treat such diseases stems from the fact that these compounds regulate, modulate and/or inhibit tyrosine kinase signal transduction by affecting the enzymatic activity of the receptor tyrosine kinases (RTKs) and/or the non-receptor tyrosine kinases and interfering with the signal transduced by such proteins.

[0119] Tyrosine kinase signal transduction plays an important role in cell proliferation, differentiation and metabolism. Abnormal cell proliferation may result in a wide array of disorders and diseases, including the development of neoplasia such as carcinoma, sarcoma, leukemia, glioblastoma, hemangioma, psoriasis, arteriosclerosis, arthritis and diabetic retinopathy (or other disorders related to uncontrolled angiogenesis and/or vasculogenesis). Thus, the combinations disclosed herein containing 3-heteroaryl-2-indolinone compounds are useful, e.g., in treating diseases resulting from abnormal tyrosine kinase signal transduction.

[0120] Cell proliferative disorders which can be treated or further studied by the present invention, include, in addition to cancers, blood vessel proliferative disorders and mesangial cell proliferative disorders.

[0121] Blood vessel proliferative disorders refer to angiogenic and vasculogenic disorders generally resulting in abnormal proliferation of blood vessels. The formation and spreading of blood vessels, or vasculogenesis and angiogenesis, respectively, play important roles in a variety of physiological processes such as embryonic development, corpus luteum formation, wound healing and organ regeneration. They also play a pivotal role in cancer development. Other examples of blood vessel proliferation disorders include arthritis, where new capillary blood vessels invade the joint and destroy cartilage, and ocular diseases, like diabetic retinopathy, where new capillaries in the retina invade the vitreous, bleed and cause blindness. Conversely, disorders related to the shrinkage, contraction or closing of blood vessels, such as restenosis, are also implicated.

[0122] Fibrotic disorders refer to the abnormal formation of extracellular matrix. Examples of fibrotic disorders include hepatic cirrhosis and mesangial cell proliferative disorders. Hepatic cirrhosis is characterized by the increase in extracellular matrix constituents resulting in the formation of a hepatic scar. Hepatic cirrhosis can cause diseases such as cirrhosis of the liver. An increased extracellular matrix resulting in a hepatic scar can also be caused by viral infection such as hepatitis. Lipocytes appear to play a major role in hepatic cirrhosis. Other fibrotic disorders implicated include atherosclerosis (see, below).

[0123] Mesangial cell proliferative disorders refer to disorders brought about by abnormal proliferation of mesangial cells. Mesangial proliferative disorders include various human renal diseases, such as glomerulonephritis, diabetic nephropathy, malignant nephrosclerosis, thrombotic microangiopathy syndromes, transplant rejection, and glomerulopathies. The PDGF-R has been implicated in the maintenance of mesangial cell proliferation. Floege et al., 1993, Kidney International 43:47S-54S.

[0124] PTKs have been associated with such cell proliferative disorders. For example, some members of the RTK family have been associated with the development of cancer. Some of these receptors, like the EGFR (Tuzi et al., 1991, Br. J. Cancer 63:227-233; Torp et al., 1992, APMIS 100:713-719) HER2/neu (Slamon et al., 1989, Science 244:707-712) and the PDGF-R (Kumabe et al., 1992, Oncogene 7:627-633) are overexpressed in many tumors and/or persistently activated by autocrine loops. In fact, in the most common and severe cancers, these receptor overexpressions (Akbasak and Suner-Akbasak et al., 1992, J. Neurol. Sci. 111:119-133; Dickson et al., 1992, Cancer Treatment Res. 61:249-273; Korc et al., 1992, J. Clin. Invest. 90:1352-1360) and autocrine loops (Lee and Donoghue, 1992, J. Cell. Biol. 118:1057-1070; Korc et al., supra; Akbasak and Suner-Akbasak et al., supra) have been demonstrated. For example, the EGFR receptor has been associated with squamous cell carcinoma, astrocytoma, glioblastoma, head and neck cancer, lung cancer and bladder cancer. HER2 has been associated with breast, ovarian, gastric, lung, pancreas and bladder cancer. The PDGF-R has been associated with glioblastoma, lung, ovarian, melanoma and prostate cancer. The RTK c-met has been generally associated with hepatocarcinogenesis and thus hepatocellular carcinoma. Additionally, c-met has been linked to malignant tumor formation. More specifically, the RTK c-met has been associated with, among other cancers, colorectal, thyroid, pancreatic and gastric carcinoma, leukemia and lymphoma. Additionally, over-expression of the c-met gene has been detected in patients with Hodgkins disease, Burkitts disease, and the lymphoma cell line.

[0125] The IGF-IR, in addition to being implicated in nutritional support and in type-II diabetes, has also been associated with several types of cancers. For example, IGF-I has been implicated as an autocrine growth stimulator for several tumor types, e.g. human breast cancer carcinoma cells (Arteaga et al., 1989, J. Clin. Invest. 84:1418-1423) and small lung tumor cells (Macauley et al., 1990, Cancer Res. 50:2511-2517). In addition, IGF-I, integrally involved in the normal growth and differentiation of the nervous system, appears to be an autocrine stimulator of human gliomas. Sandberg-Nordqvist et al., 1993, Cancer Res. 53:2475-2478. The importance of the IGF-IR and its ligands in cell proliferation is further supported by the fact that many cell types in culture (fibroblasts, epithelial cells, smooth muscle cells, T-lymphocytes, myeloid cells, chondrocytes, osteoblasts, the stem cells of the bone marrow) are stimulated to grow by IGF-1. Goldring and Goldring, 1991, Eukaryotic Gene Expression 1:301-326. In a series of recent publications, Baserga even suggests that IGF-1-R plays a central role in the mechanisms of transformation and, as such, could be a preferred target for therapeutic interventions for a broad spectrum of human malignancies. Baserga, 1995, Cancer Res. 55:249-252; Baserga, 1994, Cell 79:927-930; Coppola et al., 1994, Mol. Cell. Biol. 14:4588-4595.

[0126] The association between abnormalities in RTKs and disease are not only restricted to cancer, however. For example, RTKs have been associated with metabolic diseases like psoriasis, diabetes mellitus, wound healing, inflammation, and neurodegenerative diseases. For example, the EGF-R is indicated in corneal and dermal wound healing. Defects in the Insulin-R and the IGF-IR are indicated in type-11 diabetes mellitus. A more complete correlation between specific RTKs and their therapeutic indications is set forth in Plowman et al., 1994, DN&P 7:334-339.

[0127] Not only receptor type tyrosine kinases, but also many cellular tyrosine kinases (CTKs) including src, abl, fps, yes, fyn, lyn, lck, blk, hck, fgr, yrk (reviewed by Bolen et al., 1992, FASEB J. 6:3403-3409) are involved in the proliferative and metabolic signal transduction pathway and thus in indications of the present invention. For example, mutated src (v-src) has been demonstrated as an oncoprotein (pp60v-src) in chicken. Moreover, its cellular homolog, the proto-oncogene pp60c-src transmits oncogenic signals of many receptors. For example, overexpression of EGF-R or HER2/neu in tumors leads to the constitutive activation of pp60c-src, which is characteristic for the malignant cell but absent from the normal cell. On the other hand, mice deficient for the expression of c-src exhibit an osteopetrotic phenotype, indicating a key participation of c-src in osteoclast function and a possible involvement in related disorders. Similarly, Zap 70 is implicated in T-cell signaling.

[0128] Furthermore, the identification of CTK modulating compounds to augment or even synergize with RTK aimed blockers is an aspect of the present invention.

[0129] Finally, both RTKs and non-receptor type kinases have been connected to hyperimmune disorders.

[0130] Thus, in addition to being used to treat neoplasia, the combination therapy of the present invention may be used to treat diseases such as blood vessel proliferative disorders, fibrotic disorders, mesangial cell proliferative disorders and metabolic diseases.

[0131] As used herein, the term “cyclooxygenase-2 inhibitor” embraces compounds which selectively inhibit cyclooxygenase-2 over cyclooxygenase-1, and also includes pharmaceutically acceptable salts or esters of those compounds.

[0132] In practice, the selectivity of a COX-2 inhibitor varies depending upon the condition under which the test is performed and on the inhibitors being tested. However, for the purposes of this specification, the selectivity of a COX-2 inhibitor can be measured as a ratio of the in vitro or in vivo IC50 value for inhibition of Cox-1, divided by the IC50 value for inhibition of COX-2 (Cox-1 IC50/COX-2 IC50). A COX-2 selective inhibitor is any inhibitor for which the ratio of Cox-1 IC50 to COX-2 IC50 is greater than 1, preferably greater than 2, more preferably greater than 5, yet more preferably greater than 10, still more preferably greater than 50, and more preferably still greater than 100.

[0133] As used herein, the term “IC50” refers to the concentration of a compound that is required to produce 50% inhibition of cyclooxygenase activity.

[0134] Preferred cyclooxygenase-2 selective inhibitors of the present invention have a cyclooxygenase-2 IC50 of less than about 1 μM, more preferred of about 0.5 μM.

[0135] Preferred cycloxoygenase-2 selective inhibitors have a cyclooxygenase-1 IC50 of greater than about 1 μM, and more preferably of greater than 20 μM. Such preferred selectivity may indicate an ability to reduce the incidence of common NSAID-induced side effects.

[0136] Also included within the scope of the present invention are compounds that act as prodrugs of cyclooxygenase-2-selective inhibitors. As used herein in reference to COX-2 selective inhibitors, the term “prodrug” refers to a chemical compound that can be converted into an active COX-2 selective inhibitor by metabolic or simple chemical processes within the body of the subject. One example of a prodrug for a COX-2 selective inhibitor is parecoxib, which is a therapeutically effective prodrug of the tricyclic cyclooxygenase-2 selective inhibitor valdecoxib. An example of a preferred COX-2 selective inhibitor prodrug is parecoxib sodium. A class of prodrugs of COX-2 inhibitors is described in U.S. Pat. No. 5,932,598. References herein to “cyclooxygenase-2 selective inhibitors”, “COX-2 selective inhibitors”, etc. include prodrugs thereof unless the context precludes it.

I

[0489] Information about S-33516, mentioned above, can be found in Current Drugs Headline News, at http://www.current-drugs.com/NEWS/Inflaml.htm, 10/04/2001, where it was reported that S-33516 is a tetrahydroisoinde derivative which has IC50 values of 0.1 and 0.001 mM against cyclooxygenase-1 and cyclooxygenase-2, respectively. In human whole blood, S-33516 was reported to have an ED50=0.39 mg/kg.

[0490] The cyclooxygenase-2 selective inhibitors described above may be referred to herein collectively as COX-2 selective inhibitors, or cyclooxygenase-2 selective inhibitors.

[0491] Cyclooxygenase-2 selective inhibitors that are useful in the present invention can be supplied by any source as long as the cyclooxygenase-2 selective inhibitor is pharmaceutically acceptable. Cyclooxygenase-2-selective inhibitors can be isolated and purified from natural sources or can be synthesized. Cyclooxygenase-2-selective inhibitors should be of a quality and purity that is conventional in the trade for use in pharmaceutical products.

[0492] As used herein, an “effective amount” means the dose or effective amount to be administered to a patient and the frequency of administration to the subject which is readily determined by one or ordinary skill in the art, by the use of known techniques and by observing results obtained under analogous circumstances. The dose or effective amount to be administered to a patient and the frequency of administration to the subject can be readily determined by one of ordinary skill in the art by the use of known techniques and by observing results obtained under analogous circumstances. In determining the effective amount or dose, a number of factors are considered by the attending diagnostician, including but not limited to, the potency and duration of action of the compounds used; the nature and severity of the illness to be treated as well as on the sex, age, weight, general health and individual responsiveness of the patient to be treated, and other relevant circumstances.

[0493] The phrase “therapeutically-effective” indicates the capability of an agent to prevent, or improve the severity of the disorder, while avoiding adverse side effects typically associated with alternative therapies. The phrase “therapeutically-effective” is to be understood to be equivalent to the phrase “effective for the treatment or prevention”, and both are intended to qualify the amount of each agent for use in the combination therapy which will achieve the goal of improvement in the severity of neoplasia and the frequency of incidence over treatment of each agent by itself, while avoiding adverse side effects typically associated with alternative therapies.

[0494] 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.

[0495] For 3-heteroaryl-2-indolinone compounds used in the methods of the invention, the therapeutically effective dose contained in any combination can be estimated initially from cell culture assays. For example, a dose can be formulated in animal models to achieve a circulating concentration range that includes the IC50 as determined in cell culture (i.e., the concentration of the test compound which achieves a half-maximal inhibition of the PTK activity). Such information can be used to more accurately determine useful doses in humans.

[0496] Toxicity and therapeutic efficacy of the 3-heteroaryl-2-indolinone compounds contained in any combination described herein can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., for determining the LD50 (the dose lethal to 50% of the population) and the ED50 (the dose therapeutically effective in 50% of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index and it can be expressed as the ratio between LD50 and ED50.

[0497] Indolinone compounds which exhibit high therapeutic indices are preferred. The data obtained from these cell culture assays and animal studies can be used in formulating a range of dosage for use in humans. The dosage of such compounds lies preferably within a range of circulating concentrations that include the ED50 with little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. The exact formulation, route of administration and dosage can be chosen by the individual physician in view of the patient's condition. (See e.g., Fingl et al., 1975, in “The Pharmacological Basis of Therapeutics”, Ch. 1 p.1).

[0498] Dosage amount and interval may be adjusted individually to provide plasma levels of the active moiety which are sufficient to maintain the kinase modulating effects, or minimal effective concentration (MEC). The MEC will vary for each compound but can be estimated from in vitro data; e.g., the concentration necessary to achieve 50-90% inhibition of the kinase using the assays described herein. Dosages necessary to achieve the MEC will depend on individual characteristics and route of administration. However, HPLC assays or bioassays can be used to determine plasma concentrations.

[0499] Dosage intervals can also be determined using MEC value. 3-heteroaryl-2-indolinone compounds should be administered using a regimen which maintains plasma levels above the MEC for 10-90% of the time, preferably between 30-90% and most preferably between 50-90%. In cases of local administration or selective uptake, the effective local concentration of the drug may not be related to plasma concentration.

[0500] The amount of composition administered will, of course, be dependent on the subject being treated, on the subject's weight, the severity of the affliction, the manner of administration and the judgment of the prescribing physician.

[0501] In the present method, the amount of a 3-heteroaryl-2-indolinone compound that is used is such that, when administered with the cyclooxygenase-2 selective inhibitor, it is sufficient to constitute an effective amount of the combination. It is preferred that the dosage of the combination constitutes a therapeutically effective amount.

[0502] It is preferred that the amount of a 3-heteroaryl-2-indolinone compound that is used in combination with a COX-2 selective inhibitor for a single dosage of treatment is within a range of from about 0.001 mg/kg of body weight of the subject to about 200 mg/kg. It is more preferred that the amount is from about 0.01 mg/kg to about 20 mg/kg, even more preferred that it is from about 0.1 mg/kg to about 12 mg/kg, and yet more preferred that it is from about 0.2 mg/kg to about 10 mg/kg.

[0503] The frequency of dose will depend in part upon the half-life of a 3-heteroaryl-2-indolinone compound. If a 3-heteroaryl-2-indolinone compound has a short half life (e.g. from about 2 to 10 hours) it may be necessary to give one or more doses per day. Alternatively, if a 3-heteroaryl-2-indolinone compound has a long half-life (e.g. from about 2 to about 15 days) it may only be necessary to give a dosage once per day, per week, or even once every 1 or 2 months. A preferred dosage rate is to administer the dosage amounts described above to a subject once per day.

[0504] Similarly, the amount of COX-2 selective inhibitor that is used in the subject method may be an amount that, when administered with a 3-heteroaryl-2-indolinone compound, is sufficient to constitute an effective amount of the combination. Preferably, such amount would be sufficient to provide a therapeutically effective amount of the combination. The therapeutically effective amount can also be described herein as a neoplasia treatment or prevention, effective amount of the combination.

[0505] In the present method, the amount of COX-2 selective inhibitor that is used -in the novel method of treatment preferably ranges from about 0.01 to about 100 milligrams per day per kilogram of body weight of the subject (mg/day-kg), more preferably from about 0.1 to about 50 mg/day.kg, even more preferably from about 1 to about 20 mg/day-kg.

[0506] When the COX-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.

[0507] When the COX-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.

[0508] When the COX-2 selective inhibitor comprises celecoxib, it is preferred that the amount used is within a range of from about 1 to about 10 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.

[0509] In the present method, and in the subject compositions, a 3-heteroaryl-2-indolinone compound is administered with, or is combined with, a COX-2 selective inhibitor. It is preferred that the weight ratio of the amount of a 3-heteroaryl-2-indolinone compound to the amount of COX-2 selective inhibitor that is administered to the subject is within a range of from about 0.0001:1 to about 2000:1, more preferred is a range of from about 0.002:1 to about 1200:1, even more preferred is a range of from about 0.01:1 to about 1:1.

[0510] The combination of a 3-heteroaryl-2-indolinone compound and a COX-2 selective inhibitor can be supplied in the form of a novel therapeutic composition that is believed to be within the scope of the present invention. The relative amounts of each component in the therapeutic composition may be varied and may be as described just above. A 3-heteroaryl-2-indolinone compound and COX-2 selective inhibitor that are described above can be provided in the therapeutic composition so that the preferred amounts of each of the components are supplied by a single dosage, a single injection or a single capsule for example, or, by up to four, or more, single dosage forms.

All of the above salts can be prepared by those skilled in the art by conventional means from the corresponding compound of the present invention.

[0518] The terms “treating” or “to treat” mean to alleviate symptoms, eliminate the causation either on a temporary or permanent basis, or to prevent or slow the appearance of symptoms. The term “treatment” includes alleviation, elimination of causation of or prevention of neoplasia. Besides being useful for human treatment, these combinations are also useful for treatment of mammals, including horses, dogs, cats, rats, mice, sheep, pigs, etc.

[0519] The term “subject” for purposes of treatment includes any human or animal subject who is in need of a partcular treatment, especially the prevention of neoplasia or is afflicted with such disorder. The subject is typically a mammal.

[0520] “Mammal”, as that term is used herein, refers to any animal classified as a mammal, including humans, domestic and farm animals, and zoo, sports, or pet animals, such as dogs, horses, cats, cattle, etc. Preferably, the mammal is a human.

[0521] For methods of prevention, the subject is any human or animal subject, and preferably is a subject that is in need of prevention and/or treatment of neoplasia. The subject may be a human subject who is at risk for a disorder or condition, such as neoplasia. The subject may be at risk due to genetic predisposition, sedentary lifestyle, diet, exposure to disorder-causing agents, exposure to pathogenic agents and the like.

[0522] The pharmaceutical compositions of the present invention may be administered enterally and parenterally. Parenteral administration includes subcutaneous, intramuscular, intradermal, intramammary, intravenous, and other administrative methods known in the art. Enteral administration includes solution, tablets, sustained release capsules, enteric coated capsules, and syrups. When administered, the pharmaceutical composition may be at or near body temperature.

[0523] The phrases “combination therapy”, “co-administration”, “administration with”, or “co-therapy”, in defining the use of a cyclooxygenase-2 inhibitor agent and an indolinone, are intended to embrace administration of each agent in a sequential manner in a regimen that will provide beneficial effects of the drug combination, and are intended as well to embrace co-administration of these agents in a substantially simultaneous manner, such as in a single capsule or dosage device having a fixed ratio of these active agents or in multiple, separate capsules or dosage devices for each agent, where the separate capsules or dosage devices can be taken together contemporaneously, or taken within a period of time sufficient to receive a beneficial effect from both of the constituent agents of the combination.

[0524] Although the combination of the present invention may include administration of the 3-heteroaryl-2-indolinone component and a cyclooxygenase-2 selective inhibitor component within an effective time of each respective component, it is preferable to administer both respective components contemporaneously, and more preferable to administer both respective components in a single delivery dose.

[0525] In particular, the combinations of the present invention can be administered orally, for example, as tablets, coated tablets, dragees, troches, lozenges, aqueous or oily suspensions, dispersible powders or granules, emulsions, hard or soft capsules, or syrups or elixirs. Compositions intended for oral use may be prepared according to any method known in the art for the manufacture of pharmaceutical compositions and such compositions may contain one or more agents selected from the group consisting of sweetening agents, flavoring agents, coloring agents and preserving agents in order to provide pharmaceutically elegant and palatable preparations. Tablets contain the active ingredient in admixture with non-toxic pharmaceutically acceptable excipients which are suitable for the manufacture of tablets. These excipients may be, for example, inert diluents, such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, for example, maize starch, or alginic acid; binding agents, for example starch, gelatin or acacia, and lubricating agents, for example magnesium stearate, stearic acid or talc. The tablets may be uncoated or they may be coated by known techniques to delay disintegration and adsorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate may be employed.

[0526] Formulations for oral use may also be presented as hard gelatin capsules wherein the active ingredients are mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredients are present as such, or mixed with water or an oil medium, for example, peanut oil, liquid paraffin, or olive oil.

The oily suspensions may contain a thickening agent, for example beeswax, hard paraffin or cetyl alcohol.

[0530] Sweetening agents, such as those set forth above, and flavoring agents may be added to provide a palatable oral preparation. These compositions may be preserved by the addition of an antioxidant such as ascorbic acid.

[0531] Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, a suspending agent and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those already mentioned above. Additional excipients, for example sweetening, flavoring and coloring agents, may also be present.

[0532] Syrups and elixirs containing the novel combination may be formulated with sweetening agents, for example glycerol, sorbitol or sucrose. Such formulations may also contain a demulcent, a preservative and flavoring and coloring agents.

[0533] The present combinations can also be administered parenterally, either subcutaneously, or intravenously, or intramuscularly, or intrasternally, or by infusion techniques, in the form of sterile injectable aqueous or olagenous suspensions. Such suspensions may be formulated according to the known art using those suitable dispersing of wetting agents and suspending agents which have been mentioned above, or other acceptable agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example as a solution in 1,3-0.5 butanediol. 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, n-3 polyunsaturated fatty acids may find use in the preparation of injectables.

[0534] The subject combination can also be administered by inhalation, in the form of aerosols or solutions for nebulizers, or rectally, in the form of suppositories prepared by mixing the drug with a suitable non-irritating excipient which is solid at ordinary temperature but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials are cocoa butter and poly-ethylene glycols.

[0535] The novel compositions can also be administered topically, in the form of creams, ointments, jellies, collyriums, solutions or suspensions.

[0536] Daily dosages can vary within wide limits and will be adjusted to the individual requirements in each particular case. In general, for administration to adults, an appropriate daily dosage has been described above, although the limits that were identified as being preferred may be exceeded if expedient. The daily dosage can be administered as a single dosage or in divided dosages.

[0537] Various delivery systems include capsules, tablets, and gelatin capsules, for example.

[0538] The present invention further comprises kits that are suitable for use in performing the methods of treatment or prevention of neoplasia as described above. In one embodiment, the kit contains a first dosage form comprising a 3-heteroaryl-2-indolinone or related compound and a second dosage form comprising one or more of the cyclooxygenase-2 selective inhibitors or prodrugs thereof, in quantities sufficient to carry out the methods of the present invention.

[0889] 5. Remove drug, EGF, and DMEM. Wash cells twice with PBS. Transfer HNTG* to cells, 100 μl per well. Place on ice for 5 minutes. Meanwhile, remove blocking buffer from other ELISA plate and wash with TBST as described above.

[0890] 6. With a pipette tip securely fitted to a micropipettor, scrape cells from plate and homogenize cell material by repeatedly aspirating and dispensing the HNTG* lysis buffer. Transfer lysate to a coated, blocked, and washed ELISA plate. Incubate shaking at room temperature for one hour.

[0891] 7. Remove lysate and wash 4 times with TBST. Transfer freshly diluted anti-Ptyr antibody to ELISA plate at 100 μl per well. Incubate shaking at room temperature for 30 minutes in the presence of the anti-Ptyr antiserum (1:3000 dilution in TBST).

[0892] 8. Remove the anti-Ptyr antibody and wash 4 times with TBST. Transfer the freshly diluted TAGO anti-rabbit IgG antibody to the ELISA plate at 100 μl per well., Incubate shaking at room temperature for 30 minutes (anti-rabbit IgG antibody: 1:3000 dilution in TBST).

[0893] 9. Remove TAGO detection antibody and wash 4 times with TBST. Transfer freshly prepared ABTS/H2O2 solution to ELISA plate, 100 μl per well. Incubate shaking at room temperature for 20 minutes. (ABTS/H2O2 solution: 1.0 μl 30% H2O2 in 10 ml ABTS stock).

[0894] 10. Stop reaction by adding 50 μl 5N H2 SO4 (optional), and determine O.D. at 410 nm.

[0895] 11. The maximal phosphotyrosine signal is determined by subtracting the value of the negative controls from the positive controls. The percent inhibition of phosphotyrosine content for extract-containing wells is then calculated, after subtraction of the negative controls.

[1231] (6) After incubation with labeling reagent, the medium is removed by decanting and tapping the inverted plate on a paper towel. FixDenat solution is added (50 μl/well) and the plates are incubated at room temperature for 45 minutes on a plate shaker.

[1232] (7) The FixDenat solution is thoroughly removed by decanting and tapping the inverted plate on a paper towel. Milk is added (5% dehydrated milk in PBS, 200 μl/well) as a blocking solution and the plate is incubated for 30 minutes at room temperature on a plate shaker.

[1233] (8) The blocking solution is removed by decanting and the wells are washed once with PBS. Anti-BrdU-POD solution (1:100 dilution in PBS, 1% BSA) is added (100 μl/well) and the plate is incubated for 90 minutes at room temperature on a plate shaker.

[1234] (9) The antibody conjugate is thoroughly removed by decanting and rinsing the wells 5 times with PBS, and the plate is dried by inverting and tapping on a paper towel.

[1235] (10) TMB substrate solution is added (100 μl/well) and incubated for 20 minutes at room temperature on a plate shaker until color development is sufficient for photometric detection.

[1236] (11) The absorbance of the samples are measured at 410 nm (in “dual wavelength” mode with a filter reading at 490 nm, as a reference wavelength) on a Dynatech ELISA plate reader.

HUV-EC-C Assay

[1237] The following protocol may also be used to measure the composition's activity:

[1238] Day 0

[1239] 1. Wash and trypsinize HUV-EC-C cells (human umbilical vein endothelial cells, (American Type Culture Collection; catalogue no. 1730 CRL). Wash with Dulbecco's phosphate-buffered saline (D-PBS; obtained from Gibco BRL; catalogue no. 14190-029) 2 times at about 1 ml/10 cm.sup.2 of tissue culture flask. Trypsinize with 0.05% trypsin-EDTA in non-enzymatic cell dissociation solution (Sigma Chemical Company; catalogue no. C-1544). The 0.05% trypsin was made by diluting 0.25% trypsin/1 mM EDTA (Gibco; catalogue no. 25200-049) in the cell dissociation solution. Trypsinize with about 1 ml/25-30 cm.sup.2 of tissue culture flask for about 5 minutes at 37° C. After cells have detached from the flask, add an equal volume of assay medium and transfer to a 50 ml sterile centrifuge tube (Fisher Scientific; catalogue no. 05-539-6).

[1240] 2. Wash the cells with about 35 ml assay medium in the 50 ml sterile centrifuge, tube by adding the assay medium, centrifuge for 10 minutes at approximately 200× g, aspirate the supernatant, and resuspend with 35 ml D-PBS. Repeat the wash two more times with D-PBS, resuspend the cells in about 1 ml assay medium/15 cm2 of tissue culture flask. Assay medium consists of F12K medium (Gibco BRL; catalogue no. 21127-014)+0.5% heat-inactivated fetal bovine serum. Count the cells with a Coulter Counter.RTM.v Coulter Electronics, Inc.) and add assay medium to the cells to obtain a concentration of 0.8-1.0×105 cells/ml.

[1241] 3. Add cells to 96-well flat-bottom plates at 100 μl/well or 0.8-1.0.times.10.sup.4 cells/well; incubate about 24 h at 37° C., 5% CO2.

[1242] Day 1

[1243] 1. Make up two-fold drug titrations in separate 96-well plates, generally 50 μM on down to 0 μM. Use the same assay medium as mentioned in day 0, step 2 above. Titrations are made by adding 90 μl/well of drug at 200 μM (4× the final well concentration) to the top well of a particular plate column. Since the stock drug concentration is usually 20 mM in DMSO, the 200 μM drug concentration contains 2% DMSO. Therefore, diluent made up to 2% DMSO in assay medium (F12K+0.5% fetal bovine serum) is used as diluent for the drug titrations in order to dilute the drug but keep the DMSO concentration constant. Add this diluent to the remaining wells in the column at 60 μl/well. Take 60 μl from the 120 μl of 200 μM drug dilution in the top well of the column and mix with the 60 μl in the second well of the column. Take 60 μl from this well and mix with the 60 μl in the third well of the column, and so on until two-fold titrations are completed. When the next-to-the-last well is mixed, take 60 μl of the 120 μl in this well and discard it. Leave the last well with 60 μl of DMSO/media diluent as a non-drug-containing control. Make 9 columns of titrated drug, enough for triplicate wells each for 1) VEGF (obtained from Pepro Tech Inc., catalogue no. 100-200, 2) endothelial cell growth factor (ECGF) (also known as acidic fibroblast growth factor, or aFGF) (obtained from Boehringer Mannheim Biochemica, catalogue no. 1439 600), and assay media control. ECGF comes as a preparation with sodium heparin.

[1244] 2. Transfer 50 μl/well of the drug dilutions to the 96-well assay plates containing the 0.8-1.0×104 cells/100 μl/well of the HUV-EC-C cells from day 0 and 20 incubate .about.2 h at 37° C., 5% CO2.

[1245] 3. In triplicate, add 50 μl/well of 80 ng/ml VEGF, 20 ng/ml ECGF, or media control to each drug condition. As with the drugs, the growth factor concentrations are 4× the desired final concentration. Use the assay media from day 0 step 2 to make the concentrations of growth factors. Incubate approximately 24 hours at 37° C., 5% CO2. Each well will have 50 μl drug dilution, 50 μl growth factor or media, and 100 ul cells,=200 ul/well total. Thus the 4× concentrations of drugs and growth factors become 1× once everything has been added to the wells.

[1246] Day 2

[1247] 1. Add 3H-thymidine (Amersham; catalogue no. TRK-686) at 1 μCi/well (10 μl/well of 100 μCi/ml solution made up in RPMI media+10% heat-inactivated fetal bovine serum) and incubate about 24 h at 37° C., 5% CO2.

[1248] Note: 3H-thymidine is made up in RPMI media because all of the other applications for which we use the 3H-thymidine involve experiments done in RPMI. The media difference at this step is probably not significant. RPMI was obtained from Gibco BRL, catalogue no. 11875-051.

[1249] Day 3

[1250] 1. Freeze plates overnight at −20° C.

[1251] Day 4

[1252] 1. Thaw plates and harvest with a 96-well plate harvester (Tomtec Harvester 96.RTM.) onto filter mats (Wallac; catalogue no. 1205-401); read counts on a Wallac Betaplate™ liquid scintillation counter.

PDGF-R Cellular Assay

[1253] The PDGF cellular kinase assay was carried out as follows: cells are lysed in 0.2M Hepes, 0.15M NaCl, 10% V/V glycerol, 0.04% Triton X-100, 5 mM EDTA, 5 mM sodium vanadate and 2 mM Na+pyrophosphate; cell lysates are then added to an ELISA plate coated with an anti-PDGF receptor antibody (Genzyme); ELISA plates are coated at 0.5 μg of antibody/well in 150 μl of PBS for 18 hours at 4° C. prior to the addition of the lysate; the lysate is incubated in the coated plates for 1 hour and then washed four times in TBST (35 mM Tris-HCl pH 7.0, 0.15M NaCl, 0.1% Triton X100); anti-phosphotyrosine antibody (100 μl in PBS) is added and the mixture is incubated for 30 minutes at room temperature; the wells were then washed four times in TBST, a secondary antibody conjugated to POD (TAGO) is added to each well, and the treated wells are incubated for 30 minutes at room temperature; the wells are then washed four times in TBST, ABTS/H2O2 solution is added to each well and the wells are incubated for two minutes; absorbance is then measured at 410 nm.

Measurement of Cell Toxicity

[1258] Therapeutic compounds should be more potent in inhibiting receptor tyrosine kinase activity than in exerting a cytotoxic effect. A measure of the effectiveness and cell toxicity of a compound can be obtained by determining the therapeutic index: IC50/LD51. IC50, the dose required to achieve 50% inhibition, can be measured using standard techniques such as those described herein. LD50, the dosage which results in 50% toxicity, can also be measured by standard techniques (Mossman, 1983, J. Immunol. Methods, 65:55-63), by measuring the amount of LDH released (Korzeniewski and Callewaert, 1983, J. Immunol. Methods 64:313; Decker and Lohmann-Matthes, 1988, J. Immunol. Methods 115:61), or by measuring the lethal dose in animal models. Compounds with a large therapeutic index are preferred. The therapeutic index should be greater than 2, preferably at least 10, more preferably at least 50.

In vivo Animal Models

Xenograft Animal Models

[1259] The ability of human tumors to grow as xenografts in athymic mice (e.g., Balb/c, nu/nu) provides a useful in vivo model for studying the biological response to therapies for human tumors. Since the first successful xenotransplantation of human tumors into athymic mice, (Rygaard and Povlsen, 1969, Acta Pathol. Microbial. Scand. 77:758-760), many different human tumor cell lines (e.g., mammary, lung, genitourinary, gastrointestinal, head and neck, glioblastoma, bone, and malignant melanomas) have been transplanted and successfully grown in nude mice. Human mammary tumor cell lines, including MCF-7, ZR75-I, and MDA-MB-231, have been established as subcutaneous xenografts in nude mice (Warri et al., 1991, Int. J. Cancer 49:616-623; Ozzello and Sordat, 1980, Eur. J. Cancer 16:553-559; Osborne et al., 1985, Cancer Res. 45:584-590; Seibert et al., 1983, Cancer Res. 43:2223-2239).

Assay 1: HER2/Xenograft Animal Model

[1260] To study the effect of anti-tumor drug candidates on HER2 expressing tumors, the tumor cells should be able to grow in the absence of supplemental estrogen. Many mammary cell lines are dependent on estrogen for in vivo growth in nude mice (Osborne et al., supra), however, exogenous estrogen suppresses HER2 expression in nude mice (Warri et al., supra, Dati et al., 1990, Oncogene 5:1001-1006). For example, in the presence of estrogen, MCF-7, ZR-75-1, and T47D cells grow well in vivo, but express very low levels of HER2 (Warri et al., supra, Dati et al., supra).

[1261] The following type of xenograft protocol can be used:

[1262] 1) implant tumor cells (subcutaneously) into the hindflank of five- to six-week-old female Balbfc nu/nu athymic mice;

[1263] 2) administer the anti-tumor compound;

[1264] 3) measure tumor growth by measuring tumor volume.

[1265] The tumors can also be analyzed for the presence of a receptor, such as HER2, EGF or PDGF, by Western and immunohistochemical analyses. Using techniques known in the art, one skilled in the art can vary the above procedures, for example through the use of different treatment regimes.

Assay 2: FLK-1/Xenograft Model

[1266] The ability of the compounds of the present invention to inhibit ovarian, melanoma, prostate, lung and mammary tumor cell lines established as SC xenografts was examined. These studies were conducted using doses ranging from 1 to 75 mg/kg/day.

[1267] Materials And Methods. The tumor cells were implanted subcutaneously into the indicated strains of mice. Treatment was initiated on day 1 post implantation unless otherwise indicated (e.g. treatment of the SCID mouse related to the A375 melanoma cell line began on Day 9). Eight (8) to sixteen (16) mice comprised each test group.

[1268] Specifically:

[1269] Animals. Female athymic mice (BALB/c, nu/nu), BALB/c mice, Wistar rats and Fisher 344 rats were obtained from Simonsen Laboratories (Gilroy, Calif.). Female A/I mice were obtained from Jackson Laboratory (Bar Harbor, Me.). DA rats were obtained from B&K Universal, Inc. (Fremont, Calif.). Athymic R/Nu rats, DBA/2N mice, and BALB/c mice were obtained from Harlan Sprague Dawley (Indianapolis, Ind.). Female C57BU6 mice were obtained from Taconic (Germantown, N.Y.). All animals were maintained under clean-room conditions in Micro-isolator cages with Alpha-dri bedding. They received sterile rodent chow and water ad libitum.

[1270] All procedures were conducted in accordance with the NIH Guide for the Care and Use Of Laboratory Animals.

[1271] Subcutaneous Xenograft Model. Cell lines were grown in appropriate medium as described. Cells were harvested at or near confluency with 0.05% Trypsin-EDTA and pelleted at 450.times.g for 10 min. Pellets were resuspended in sterile PBS or media (without FBS) to a suitable concentration indicated in the Figure legends and the cells were implanted into the hindflank of mice. Tumor growth-was measured over 3 to 6 weeks using venier calipers and tumor volumes were calculated as a product of length x width x height unless otherwise indicated. P values were calculated using the Students' t-test.

[1272] Different concentrations of a compound in 50-100 μl excipient (dimethylsulfoxide, PBTE, PBTE6C:D5W, or PBTE:D5W) were delivered by IP injection.

[1273] Intracerebral Xenograft Model. For the mouse IC model, rat C6 glioma cells were harvested and suspended in sterile PBS at a concentration of 2.5×107 cells/ml and placed on ice. Cells were implanted into BALB/c, nu/nu mice in the following manner: the frontoparietal scalps of mice were shaved with animal clippers if necessary before swabbing with 70% ethanol. Animals were anesthetized with isofluorane and the needle was inserted through the skull into the left hemisphere of the brain. Cells were dispensed from Hamilton Gas-tight Syringes using-30 ga ½ inch needles fitted with sleeves that allowed only a 3

[1274] mm penetration. A repeater dispenser was used for accurate delivery of 4 μl of cell suspension. Animals were monitored daily for well-being and were sacrificed when they had a weight loss of about 40% and/or showed neurological symptoms. For the rat IC model, rats (Wistar, Sprague Dawley, Fisher 344, or athymic R/Nu; approximately 200400 g (some 3-400 g)) were anesthetized by an IP injection of 100 mg/kg Ketaset (ketamine hydrochloride; Aveco, Fort Dodge, Iowa) and 5 mg/kg Rompun (xylazine, 2% solution; Bayer, Germany). After onset of anesthesia, the scalp was shaved and the animal was oriented

[1275] in a stereotaxic apparatus (Stoelting, Wood Dale, Ill.). The skin at the incision site was cleaned 3 times with alternating swabs of 70% ethanol and 10% Povidone-Iodine. A median 1.0-1.5 cm incision was made in the scalp using a sterile surgical blade. The skin was detached slightly and pulled to the sides to expose the sutures on the skull surface. A dental drill (Stoelting, Wood Dale, Ill.) was used to make a small (1-2 mm diameter) burrhole in the skull approximately 1 mm anterior and 2 mm lateral to the bregma. The cell suspension was drawn into a 50 μl Hamilton syringe fitted with a 23 or 25 g a standard bevel needle.

[1276] The syringe was oriented in the burrhole at the level of the arachnoidea and lowered until the tip of the needle was 3 mm deep into the brain structure, where the cell suspension was slowly injected. After cells were injected, the needle was left in the burrhole for 1-2 minutes to allow for complete delivery of the cells. The skull was cleaned and the skin was closed with 2 to 3 sutures. Animals were observed for recovery from surgery and anesthesia. Throughout the experiment, animals were observed at least twice each day for development of symptoms associated with progression of intracerebral tumor. Animals displaying advanced symptoms (leaning, loss of balance, dehydration, loss of appetite, loss of coordination, cessation of grooming activities, and/or significant weight loss) were humanely sacrificed and the organs and tissues of interest were resected.

[1277] Intrapertoneal Model. Cell lines were grown in the appropriate media. Cells were harvested and washed in sterile PBS or medium without FBS, resuspended to a suitable concentration, and injected into the IP cavity of mice of the appropriate strain. Mice were observed daily for the occurrence of ascites formation. Individual animals were sacrificed when they presented with a weight gain of 40%, or when the IP tumor burden began to cause undue stress and pain to the animal.

In vivo VEGF Pellet Model

[1278] In the following example, the Pellet Model was used to test a compound's activity against the FLK-1 receptor and against disorders associated with the formation of blood vessels. In this model, VEGF is packaged into a time-release pellet and implanted subcutaneously on the abdomen of nude mice to induce a ‘reddening’ response and subsequent swelling around the pellet. Potential FLK-1 inhibitors may then be implanted in methylcellulose near the VEGF pellet to determine whether such inhibitor may be used to inhibit the “reddening” response and subsequent swelling.

[1279] Materials And Methods. The following materials were used:

[1280] 1) VEGF-human recombinant lyophilized product is commercially available and may be obtained from Peprotech, Inc., Princeton Business Park, G2; P.O. box 275, Rocky Hill, N.J. 08553.

[1281] 2) VEGF packaged into 21 day release pellets were obtained from Innovative Research of America (Innovative Research of America, 3361 Executive Parkway, P.O. Box 2746, Toledo, Ohio 43606), using patented matrix driven delivery system. Pellets were packaged at 0.20, 0.21, or 2.1 μg VEGF/pellet. These doses approximate 10 and 100 ng/day release of VEGF.

[1282] 3) Methylcellulose

[1283] 4) Water (sterile)

[1284] 5) Methanol

[1285] 6) Appropriate drugs/inhibitors

[1286] 7) 10 cm culture plates

[1287] 8 ) parafilm

[1288] The following protocol was then followed to conduct the VEGF pellet model:

[1289] 1) VEGF, purchased from Peprotech, was sent to Innovative Research for Custom Pellet preparation;

[1290] 2) Methylcellulose prepared at 1.5% (w/v) in sterile water;

[1291] 3) Drugs solubilized in methanol (usual concentration range=10 to 20 mg/ml);

[1292] 4) Place sterile parafilm in sterile 10 cm plates;

[1293] 5) 150 μl of drug in methanol added to 1.35 ml of 1.5% methylcellulose and mixed/vortexed thoroughly;

[1294] 6) 25 μl aliquots of homogenate placed on parafilm and dried into discs;

[1295] 7) Mice (6-10 wk. Balb/C athymic nu/nu, female) were anesthetized via isoflurane inhalation;

[1296] 8) VEGF pellets and methylcellulose discs were implanted subcutaneously on the abdomen; and

[1297] 9) Mice were scored at 24 hours and 48 hours for reddening and swelling response.

[1298] The specific experimental design used in this example was:

[1299] N=4 animals/group

[1300] Controls: VEGF pellet+drug placebo

[1301] VEGF placebo+drug pellet

[1302] Experimental Results. The compounds of the present invention are expected to demonstrate activity according to this assay.

Mammary Fat Pad Model

[1303] Because of the established role played by many of the RTKs, e.g., the HER2 receptor, in breast cancer, the mammary fat pad model is particularly useful for measuring the efficacy of compounds which inhibit such RTKs. By implanting tumor cells directly into the location of interest, in situ models more accurately reflect the biology of tumor development than do subcutaneous models. Human mammary cell lines, including MCF-7, have been grown in the mammary fat pad of athymic mice. Shafie and Grantham, 1981, Natl. Cancer Instit. 67:51-56; Gottardis et al., 1988, J. Steroid Biochem. 30:311-314. More specifically, the following procedure can be used to measure the inhibitory effect of a compound on the HER2 receptor:

[1304] 1) Implant, at various concentrations, MDA-MB-231 and MCF-7 cells transfected with HER-2 into the axillary mammary fat pads of female athymic mice;

[1305] 2) Administer the compound; and

[1306] 3) Measure the tumor growth at various time points.

[1307] The tumors can also be analyzed for the presence of a receptor such as HER2, by Western and immunohistochemical analyses. Using techniques known in the art, one skilled in the art can vary the above procedures, for example through the use of different treatment regimes.

Tumor Invasion Model

[1308] The following tumor invasion model has been developed and may be used for the evaluation of therapeutic value and efficacy of compositions of interest.

[1309] Procedure

[1310] 8 week old nude mice (female) (Simonsen Inc.) were used as experimental . 15s animals. Implantation of tumor cells was performed in a laminar flow hood. For anesthesia, Xylazine/Ketamine Cocktail (100 mg/kg ketamine and 5 mg/kg) are administered intraperitoneally. A midline incision is done to expose the abdominal cavity (approximately 1.5 cm in length) to inject 107 tumor cells in a volume of 100 μl medium. The cells are injected either into the duodenal lobe of the pancreas or under the serosa of the colon. The peritoneum and muscles are closed with a 6-0 silk continuous suture and the skin was closed by using would clips. Animals were observed daily.

Analysis

[1311] After 2-6 weeks, depending on gross observations of the animals, the mice are sacrificed, and the local tumor metastases, to various organs (lung, liver, brain, stomach, spleen, heart, muscle) are excised and analyzed (measurements of tumor size, grade of invasion, immunochemistry, and in situ hybridization).

Combination of Celecoxib and SU-5416 Results in Tumor Inhibition in HN1483 Tumor Model

[1315] Human tumor xenograft nude mice (HN1483) were used to investigate the tumor inhibitive effects of combinations of Celecoxib and SU-5416. Human tumor xenograft nude mouse models of head and neck squamous cell carcinoma (1483 cell line),express COX-2 in the tumor cells and in the vascularture, similar to human epithelial cancers. Matrigel (30%) is mixed with cell suspension which results in a 100% occurrence of tumor growth. In this way, the HN1483 mice model human epithelial cancers expressing cyclooxgenase-2 (COX-2) in the tumor cells and in the vasculature and are a good model to correlate efficacy of anti-cancer drugs including COX-2 inhibitors to efficacy in humans.

HN1483 Protocol

Materials and Methods

[1316] Cell Culture:

[1317] 1483 human head and neck squamous cell carcinoma (HNSCC) cells are stored in frozen vials containing 3×106 cells, 90% fetal bovine serum (FBS) and 10% dimethyl sulfoxide (DMSO). Take a frozen vial and quickly thaw at 37° C. and placed in a T-162 cm2 (Corning) flask containing D-MEM/F12 media (GibcoBRL) with 15 mM Hepes buffer, L-glutamine, pyridoxine hydrochloride and 10% FBS. Cells are grown in a incubator with 5% CO2 and temperature at 37° C. Media is change every other day and cells are passed when at 80-90% confluence. For passing of cells, wash flask with 10 ml of phosphate buffered saline (PBS), aspirate off and add 2 ml of trypsin/EDTA (0.25% /1 mM, GibcoBRL) place back in Incubator, after 5 min cells will detach. Add 8 ml of above media to flask rinse and transfer to a sterile 50 ml centrifuge tube. Add 30 ml more of media and mix and count cells using a hemacytometer, plate out cells in a T-162 cm2 containing 34×106 cells.

[1318] 1483 Animal Model:

[1319] Change media 24 hours before harvest of 1483 cells before injection in to nude mice. Trypsinize 1483 cells as described above in cell culture section. Count cells and determine number of cells. Centrifuge cells down at 1000 rpm for 5 minutes at room temperature. Resuspened cell pellets and pool them (if multiple 50 ml centrifuge tubes) into one 50 ml centrifuge tube with Hank's buffered saline solution (HBSS, GibcoBRL) and centrifuge as before. Extra cells may be obtained, if prefered. Prepare the cells for injecting into mice. 1483 cells are injected at 1×106 cells in 0.03 ml/mouse. 100 mice×0.03 ml=3 ml total volume. Cells are injected with 30% Matrigel (Collaborative Biomedical Products) and 70% HBSS. Resuspend pooled pellet with 2.1 ml (70%) of cold HBSS then add 0.9 ml (30%) of thawed liquefied cold Matrigel and mix well on ice. Keep this cell prep on ice at all times prior to injecting into mice.

[1320] Male nude mice age 4-6 weeks old were used in the studies (Harlen). Mice are anesthetized using CO2/O2 gas and mice are injected in the middle of the right hind paw using a 0.5 cc tuberculin syringe (Beckerson & Dickerson). Mice are weighed for body weight on day of injection (Day 0) for baseline weight for start of study. Starting on day 7 mice are weighed and right hind paw are measure for paw tumor volume using a plethysmometer (Stoelting Co.). The plethysmometer is a machine that measure paw volume by water displacement. A few left non-injected paws are measured and averaged for a background measurement to subtract from the right tumor bearing paw. Mice are weighed and measured throughout the study on days 7, 10, 14,17, 21, 24 and 28. Animals can be started on compound treatment on day 0 (prophylactic) or once there is a established tumor around day 7 (therapeutic). Around day 30 vehicle (control) mice will have large tumors (˜1.0-1.5 ml) and start to lose weight, at this time, vehicle animals may be terminated.

Protocol for Treatement of HN1483 Mice with Celecoxib. SU-5416 and Combinations Thereof

[1321] Outcomes:

[1322] 1.) Tumor growth, inhibition

[1323] 2.) Body weight as health assessment

[1324] Cells will be injected into the right paws at a concentration of 1×106 cells/paw in HBSS with 30% Matrigel.

[1325] SU-5416 was given s.c. daily and Celecoxib will be administered half in the meal and half by gavage at 11:00am. Animals were ear notched and housed in polycarbs with bedding, 4 animals/polycarb. Animals were placed on normal Chow meal upon arrival and placed on test compound in Chow meal when tumors are 100-200 ul in size and continued on compound meal throughout study. Body weight was measured twice weekly. Tumor Volume was measured twice a week using a plethysmometer.
