The present invention encompasses methods for simultaneously modulating the activities of multiple kinases or kinase pathways, including those implicated in processes important for cell survival, proliferation, growth and malignant transformation, motility and invasion. As such, the invention also encompasses methods for treating, preventing, or managing conditions, diseases, and disorders associated with protein kinases or protein kinase pathways, such as proliferative disorders and cancer, inflammatory disorders, including diabetes and obesity and abnormal angiogenesis and diseases related thereto. In particular, the methods contemplated by the invention comprise treating, preventing, or managing a disease, condition, or disorder with single-agent therapies that specifically target multiple kinases or kinase pathways. In one embodiment, the single agent therapy preferably modulates the activity of multiple kinases or kinase pathways over that of other kinases; in other words, the effect of the single agent therapy is selective for specific sets of kinases. In sum, the invention contemplates the identification and use of single agents that target the right combination of multiple pathways that are clinically effective in a particular disease setting.
The connection between abnormal protein phosphorylation and the cause or consequence of diseases has been known for over 20 years. Accordingly, protein kinases have become a very important group of drug targets. See Cohen, Nature, 1:309-315 (2002). Various protein kinase inhibitors have been used clinically in the treatment of a wide variety of diseases, such as cancer and chronic inflammatory diseases, including diabetes and stroke. See Cohen, Eur. J. Biochem., 268:5001-5010 (2001).
The protein kinases are a large and diverse family of enzymes that catalyze protein phosphorylation and play a critical role in cellular signaling. Protein kinases may exert positive or negative regulatory effects, depending upon their target protein. Protein kinases are involved in specific signaling pathways which regulate cell functions such as, but not limited to, metabolism, cell cycle progression, cell adhesion, vascular function, apoptosis, and angiogenesis. Malfunctions of cellular signaling have been associated with many diseases, the most characterized of which include cancer and diabetes. The regulation of signal transduction by cytokines and the association of signal molecules with protooncogenes and tumor suppressor genes have been well documented. Similarly, the connection between diabetes and related conditions, and deregulated levels of protein kinases, has been demonstrated. See e.g., Sridhar et al. Pharmaceutical Research, 17(11):1345-1353 (2000). Viral infections and the conditions related thereto have also been associated with the regulation of protein kinases. Park et al. Cell 101 (7), 777-787 (2000).
Protein kinases can be divided into broad groups based upon the identity of the amino acid(s) that they target (serine/threonine, tyrosine, lysine, and histidine). For example, tyrosine kinases include receptor tyrosine kinases (RTKs), such as growth factors and non-receptor tyrosine kinases, such as the src kinase family. There are also dual-specific protein kinases that target both tyrosine and serine/threonine, such as cyclin dependent kinases (CDKs) and mitogen-activated protein kinases (MAPKs). Any particular cell contains many protein kinases, some of which phosphorylate other protein kinases. Some protein kinases phosphorylate many different proteins, others phosphorylate only a single protein. Not surprisingly, there are numerous classes of protein kinases. Upon receiving a signal, some proteins may also undergo auto-phosphorylation.
The protein tyrosine kinases (PTKs) compose a large family of kinases that regulate cell to cell signals involved in growth, differentiation, adhesion, motility, and death. Robinson et al., Oncogene 19:5548-5557 (2000). Members of the tyrosine kinase include, but are not limited to, Yes, BMX, Syk, EphA1, FGFR3, RYK, MUSK, JAK1 and EGFR. Tyrosine kinases are distinguished into two classes, i.e., the receptor type and non-receptor type tyrosine kinases. Interestingly, the entire of family of tyrosine kinases is quite large—consisting of at least 90 characterized kinases with at least 58 receptor type and at least 32 nonreceptor type kinases comprising at least 30 total subfamilies. Robinson et al., Oncogene 19:5548-5557 (2000). Tyrosine kinases have been implicated in a number of diseases in humans, including diabetes and cancer. Robinson et al. at page 5548. Tyrosine kinases are often involved in most forms of human malignancies and have been linked to a wide variety of congenital syndromes. Robertson et al., Trends Genet. 16:265-271 (2000).
The non-receptor tyrosine kinases represent a group of intracellular enzymes that lack extracellular and transmembrane sequences. Currently, over 32 families of non-receptor tyrosine kinases have been identified. Robinson et al., Oncogene 19:5548-5557 (2000). Examples are Src, Btk, Csk, ZAP70, Kak families. In particular, the Src family of non-receptor tyrosine kinase family is the largest, consisting of Src, Yes, Fyn, Lyn, Lck, Blk, Hck, Fgr and Yrk protein tyrosine kinases. The Src family of kinases have been linked to oncogenesis, cell proliferation and tumor progression. A detailed discussion of non-receptor protein tyrosine kinases is available in Oncogene 8:2025-2031 (1993). Many of these protein tyrosine kinases have been found to be involved in cellular signaling pathways involved in various pathological conditions including but not limited to cancer and hyperproliferative disorders and immune disorders.
The cyclin dependent kinases CDKs represent a group of intracellular enzymes that control progression through the cell cycle and have essential roles in cell proliferation. See Cohen, Nature, 1:309-315 (2002). Examples of CDKs include, but are not limited to, cyclin dependent kinase 2 (CDK2), cyclin dependent kinase 7 (CDK7), cyclin dependent kinase 6 (CDK6) and cell division control 2 protein (CDC2). CDKs have been implicated in the regulation of transitions between different phases of the cell cycle, such as the progression from a quiescent stage in GI (the gap between mitosis and the onset of DNA replication for a new round of cell division) to S (the period of active DNA synthesis), or the progression from G2 to M phase, in which active mitosis and cell division occur. See e.g., the articles compiled in Science, vol. 274 (1996), pp. 1643-1677; and Ann. Rev. Cell Dev Biol., vol. 13 (1997), pp. 261-291. CDK complexes are formed through association of a regulatory cyclin subunit (e.g., cyclin A, B1, B2, D1, D2, D3, and E) and a catalytic kinase subunit (e.g., cdc2 (CDK1), CDK2, CDK4, CDK5, and CDK6). As the name implies, CDKs display an absolute dependence on the cyclin subunit in order to phosphorylate their target substrates, and different kinase/cyclin pairs function to regulate progression through specific portions of the cell cycle. CDKs have been implicated in various disease states, including but not limited to, those displaying the cancer phenotype, various neoplastic disorders and in neurological disorders. Hunter, Cell 100: 113-127 (2000).
The mitogen activated protein (MAP) kinases participate in the transduction of signals to the nucleus of the cell in response to extracellular stimuli. Examples of MAP kinases include, but are not limited to, mitogen activated protein kinase 3 (MAPK3), mitogen-activated protein kinase 1 (ERK2), mitogen-activated protein kinase 7 (MAPK7), mitogen-activated protein kinase 8 (JNK1), mitogen-activated protein kinase 14 (p38 alpha), mitogen-activated protein kinase 10 (MAPK 10), JNK3 alpha protein kinase, stress-activated protein kinase JNK2 and mitogen-activated protein kinase 14 (MAPK14). MAP kinases are a family of proline-directed serine/threonine kinases that mediate signal transduction from extracellular receptors or heath shock, or UV radiation. See Sridhar et al., Pharmaceutical Research, 17:11 1345-1353 (2000). MAP kinases activate through the phosphorylation of theonine and tyrosine by dual-specificity protein kinases, including tyrosine kinases such as growth factors. Cell proliferation and differentiation have been shown to be under the regulatory control of multiple MAP kinase cascades. See Sridhar et al., Pharmaceutical Research, 17:11 1345-1353 (2000). As such, the MAP kinase pathway plays critical roles in a number of disease states. For example, defects in activities of MAP kinases have been shown to lead to aberrant cell proliferation and carcinogenesis. See Hu et al., Cell Growth Differ. 11:191-200 (2000); and Das et al., Breast Cancer Res. Treat. 40:141 (1996). Moreover, MAP kinase activity has also been implicated in insulin resistance associated with type-2 diabetes. See Virkamaki et al., J. Clin. Invest. 103:931-943 (1999).
The p90 ribosomal S6 kinases (Rsk) are serine/threonine kinases. The Rsk family members function in mitogen-activated cell growth and proliferation, differentiation, and cell survival. Examples of members of the Rsk family of kinases include, but are not limited to, ribosomal protein S6 kinase, 90 kDa, polypeptide 2 (Rsk3), ribosomal protein S6 kinase, 90 kDa, polypeptide 6 (Rsk4), ribosomal protein S6 kinase, 90 kDa, polypeptide 3 (Rsk2) and ribosomal protein S6 kinase, 90 kDa, polypeptide 1 (Rsk1/p90Rsk). The Rsk family members are activated by extracellular signal-related kinases ½ and phosphoinositide-dependent protein kinase 1. Frodin and Gammeltoft, Mol. Cell. Endocrinol. 151:65-77 (1999). Under basal conditions, RSK kinases are localized in the cytoplasm of cells and upon stimulation by mitogens, the activated (phosphorylated by extracellular-related kinase) RSK transiently translocates to the plasma membrane where they become fully activated. The fully activated RSK phosphorylates substrates that are involved in cell growth, proliferation, differentiation, and cell survival. Richards et al., Curr. Biol. 9:810-820 (1999); Richards et al., Mol. Cell. Biol. 21:7470-7480 (2001). RSK signaling pathways have also been associated with the modulation of the cell cycle. Gross et al., J. Biol. Chem. 276(49): 46099-46103 (2001). Current data suggests that small molecules that inhibit Rsk may be useful therapeutic agents for the prevention and treatment of cancer and inflammatory diseases.
Members of the checkpoint protein kinase family are serine/threonine kinases that play an important role in cell cycle progression. Examples of members of the checkpoint family include, but are not limited to, CHK1 and CHK2. Checkpoints are control systems that coordinate cell cycle progression by influencing the formation, activation and subsequent inactivation of the cyclin-dependent kinases. Checkpoints prevent cell cycle progression at inappropriate times, maintain the metabolic balance of cells while the cell is arrested, and in some instances can induce apoptosis (programmed cell death) when the requirements of the checkpoint have not been met. See e.g., O'Connor, Cancer Surveys, 29: 151-182 (1997); Nurse, Cell, 91: 865-867 (1997); Hartwell et al., Science, 266: 1821-1828 (1994); Hartwell et al., Science, 246: 629-634 (1989). Members of the checkpoint family of kinases have been implicated in cell proliferative disorders, cancer phenotypes and other diseases related to DNA damage and repair. Kohn, Mol. Biol. Cell 10:2703-2734 (1999); Ohi and Gould, Curr. Opin. Cell Biol. 11:267-273 (1999); Peng, et al., Science 277:1501-1505 (1997).
Aurora kinases are a family of multigene mitotic serine-threonine kinases that functions as a class of novel oncogenes. These kinases comprise aurora-A and aurora-B members. Aurora kinases are hyperactivated and/or over-expressed in several solid tumors including but not limited to, breast, ovary, prostate, pancreas, and colorectal cancers. In particular aurora-A is a centrosome kinase that plays an important role cell cycle progression and cell proliferation. Aurora-A is located in the 20q13 chromosome region that is frequently amplified in several different types of malignant tumors such as colorectal, breast and bladder cancers. There is also a high correlation between aurora-A and high histo-prognostic grade aneuploidy, making the kinase a potential prognostic vehicle. Inhibition of aurora kinase activity could help to reduce cell proliferation, tumor growth and potentially tumorigenesis. A detailed description of aurora kinase function is reviewed in Oncogene 21:6175-6183 (2002).
The Rho-associated coiled-coil-containing protein serine/threonine kinases ROCK-I and ROCK-II are thought to play a major role in cytoskeletal dynamics by serving as downstream effectors of the Rho/Rac family of cytokine- and growth factor-activated small GTPases. ROCKs phosphorylate various substrates, including, but not limited to, myosin light chain phosphatase, myosin light chain, ezrin-radixin-moesin proteins and LIM (for Lin11, Isl1 and Mec3) kinases. ROCKs also mediate the formation of actin stress fibers and focal adhesions in various cell types. ROCKs have an important role in cell migration by enhancing cell contractility. They are required for tail retraction of monocytes and cancer cells, and a ROCK inhibitor has been used to reduce tumor-cell dissemination in vivo. Recent experiments have defined new functions of ROCKs in cells, including centrosome positioning and cell-size regulation, which might contribute to various physiological and pathological states. See Nature Reviews Mol. Cell Biol. 4, 446-456 (2003). The ROCK family members are attractive intervention targets for a variety of pathologies, including cancer and cardiovascular disease. For example, Rho kinase inhibitors can be useful therapeutic agents for hypertension, angina pectoris, and asthma. Furthermore, Rho is expected to play a role in peripheral circulation disorders, arteriosclerosis, inflammation, and autoimmune disease and as such, is a useful target for therapy.
The 70 kDa ribosomal S6 kinase (p70S6K) is activated by numerous mitogens, growth factors and hormones. Activation of p70S6K occurs through phosphorylation at a number of sites and the primary target of the activated kinase is the 40S ribosomal protein S6, a major component of the machinery involved in protein synthesis in mammalian cells. In addition to its involvement in regulating translation, p7OS6K activation has been implicated in cell cycle control, neuronal cell differentiation, regulation of cell motility and a cellular response that is important in tumor metastases, immunity and tissue repair. Modulation of p70S6 kinase activity may have therapeutic implications in disorders such as cancer, inflammation, and various neuropathies. A detailed discussion of p70S6K kinases can be found in Prog. Cell Cycle Res. 1:21-32 (1995), and Immunol Cell Biol. 78(4):447-51 (2000).
Glycogen synthase kinase 3 (GSK-3) is a ubiquitously expressed constitutively active serine/threonine kinase that phosphorylates cellular substrates and thereby regulates a wide variety of cellular functions, including development, metabolism, gene transcription, protein translation, cytoskeletal organization, cell cycle regulation, and apoptosis. GSK-3 was initially described as a key enzyme involved in glycogen metabolism, but is now known to regulate a diverse array of cell functions. Two forms of the enzyme, GSK-3α and GSK-3β, have been previously identified. The activity of GSK-3β is negatively regulated by protein kinase B/Akt and by the Wnt signaling pathway. Small molecules inhibitors of GSK-3 may, therefore, have several therapeutic uses, including the treatment of neurodegenerative diseases, diabetes type II, bipolar disorders, stroke, cancer, and chronic inflammatory disease. Reviewed in Role of glycogen synthase kinase-3 in cancer: regulation by Wnts and other signaling pathways (Adv Cancer Res.;84:203-29, 2002); Glycogen synthase kinase 3 (GSK-3) inhibitors as new promising drugs for diabetes, neurodegeneration, cancer, and inflammation (Med Res Rev.; 22(4):373-84, 2002); Role of glycogen synthase kinase-3 in the phosphatidylinositol 3-Kinase/Akt cell survival pathway. (J. Biol Chem., 273(32): 19929-32, 1998).
Because protein kinases regulate nearly every cellular process, including metabolism, cell proliferation, cell differentiation, and cell survival, they are attractive targets for therapeutic intervention for various disease states. For example, cell-cycle control and angiogenesis, in which protein kinases play a pivotal role are cellular processes associated with numerous disease conditions such as but not limited to cancer, inflammatory diseases, abnormal angiogenesis and diseases related thereto, atherosclerosis, macular degeneration, diabetes, obesity, and pain.
Protein kinases have become attractive targets for the treatment of cancers. Fabbro et al., Pharmacology & Therapeutics 93:79-98 (2002). It has been proposed that the involvement of protein kinases in the development of human malignancies may occur by: (1) genomic rearrangements (e.g., BCR-ABL in chronic myelogenous leukemia), (2) mutations leading to constitutively active kinase activity, such as acute myelogenous leukemia and gastrointestinal tumors, (3) deregulation of kinase activity by activation of oncogenes or loss of tumor suppressor functions, such as in cancers with oncogenic RAS, (4) deregulation of kinase activity by over-expression, as in the case of EGFR and (5) ectopic expression of growth factors that can contribute to the development and maintenance of the neoplastic phenotype. Fabbro et al., Pharmacology & Therapeutics 93:79-98 (2002).
Certain cancers are associated with angiogenesis. Angiogenesis is the growth of new capillary blood vessels from pre-existing vasculature. Risau, W., Nature 386:671-674 (1997). It has been shown that protein kinases can contribute to the development and maintenance of the neoplastic phenotype. Fabbro et al., Pharmacology & Therapeutics 93:79-98 (2002). For example, VEGF A-D and their four receptors have been implicated in phenotypes that involve neovascualrization and enhanced vascular permeability, such as tumor angiogenesis and lymphangiogenesis. Matter, A., Drug Discov. Today 6:1005-1023 (2001).
Cardiovascular disease (“CVD”) accounts for nearly one quarter of total annual deaths worldwide. Vascular disorders such as atherosclerosis and restenosis result from dysregulated growth of the vessel walls and the restriction of blood flow to vital organs. Various kinase pathways, e.g. JNK, are activated by atherogenic stimuli and regulated through local cytokine and growth factor production in vascular cells. Yang et al., Immunity 9:575 (1998). Ischemia and ischemia coupled with reperfusion in the heart, kidney or brain result in cell death and scar formation, which can ultimately lead to congestive heart failure, renal failure or cerebral dysfumction. In organ transplantation, reperfusion of previously ischemic donor organs results in acute leukocyte-mediated tissue injury and delay of graft function. Ischemia and reperfusion pathways are mediated by various kinases. For example, the JNK pathway has been linked to leukocyte-mediated tissue damage. Li et al., Mol. Cell. Biol. 16:5947-5954 (1996). Finally, enhanced apoptosis in cardiac tissues has also been linked to kinase activity. Pombo et al., J. Biol. Chem. 269:26546-26551 (1994).
The elucidation of the intricacy of protein kinase pathways and the complexity of the relationship and interaction among and between the various protein kinases and kinase pathways highlights the importance of developing pharmaceutical agents capable of acting as protein kinase modulators, regulators or inhibitors that have beneficial activity on multiple kinases or multiple kinase pathways.
It has been recognized that a single agent approach that specifically targets one kinase or one kinase pathway may be inadequate to treat diseases and disorders, in particular cancer, for several reasons. The single agent approach is a limited approach for the treatment of very complex diseases, conditions and disorders. For example, mathematical models have suggested that 5 to 7 mutations are necessary for the progression from a normal cell to malignant transformation. Additionally, other events (such as DNA methylation) can occur that modify the expression of existing genes.
Thus, it is widely recognized that cancer is the result of alterations in multiple pathways, in particular protein kinase pathways that are associated with processes such as cell growth, proliferation, apoptosis, motility, or invasion. In a majority of cancers, a common feature is the simultaneous overexpression and/or hyper-activation of a variety of protein kinases, such as receptor and non-receptor kinases, serine/threonine kinases, PI3 kinases and cell cycle associated kinases. In fact, several of these kinases, either alone or in conjunction with other kinases, have been implicated in a number of processes important for cell survival, proliferation, growth and malignant transformation, motility and invasion leading to metastasis and angiogenesis or inflammation, and diseases, disorders, and conditions associated therewith.
Accordingly, blocking one target kinase may not be clinically sufficient because there are multiple target kinases that affect the progression of a condition, disease, or disorder. In addition, blocking one target kinase may not be clinically sufficient because redundant kinase-mediated pathways and alternative oncogenic or inflammatory mechanisms may compensate for the blocked target kinase. Moreover, the use of a single agent can also increase the chances that resistance to that agent will develop.
It has therefore been suggested that due to the complexity of intracellular signaling cascades of protein kinase pathways, agents that affect multiple pathways simultaneously may be required for meaningful clinical activity. Although it has been suggested that a single agent that provides combinatorial effects is an attractive notion, there is a need to identify and use single agents that target the right combination of multiple pathways that are clinically effective in a particular disease setting. Indeed, it is known that some kinase drugs, such as Gleevec®, do target several kinases at once. Gleevec® primarily targets a mutant fusion protein containing the abl kinase, which is created by a 9:22 chromosomal translocation event; Gleevec® also targets c-kit, a tyrosine kinase implicated in gastrointestinal stromal tumors (GIST). However, in recent clinical trials, patients have developed resistance to Gleevec® or have shown incomplete response to treatment.
51 It has also been suggested that a single agent could target the primary cause of a disease and thereby regulate the downstream pathways merely by targeting one specific molecule. For example, a viral infection often affects the regulation of multiple kinases and it has been found that an agent that inhibits viral replication can, as a result, inhibit the activation of all of the multiple kinases activated by the virus. However, due to the complexity of intracellular signaling cascades of protein kinase pathways and the diseases that they are involved in, there is a need for single agents that affect multiple pathways simultaneously by directly targeting the specific kinases and/or kinase pathways. In particular, there is a need to identify single agents that are capable of simultaneously targeting multiple kinases or kinase pathways and capable of directly and selectively targeting a particular kinase and/or kinase pathway while not affecting other kinases and/or pathways. For example, rather than using a single agent that inhibits the activation of all of the multiple kinases activated by a virus in a viral infection, the single agent can simultaneously and selectively inhibit certain kinases that are activated.
An additional strategy for targeting multiple kinases or kinase pathways has been to use cocktails of single target drugs. Although the use of drug combinations in the clinic has shown promise, there is still a need to develop single agent drugs that are capable of targeting multiple kinases or kinase pathways because the use of a single agent is more pragmatic for a variety of reasons, including the ease and simplicity of administration. Moreover, it is already known that certain treatment regimens utilizing multiple agents which each target single pathways can be associated with complications, including unpleasant side effects and toxicity.
Accordingly, there remains a need for the development of methods comprising the use of a single agent drug capable of targeting specific sets of kinases or kinase pathways, in particular the right combination of multiple targets thereby achieving clinical efficacy.
The present invention is based in part on the discovery that small molecule kinase inhibitors capable of simultaneously inhibiting multiple kinases (also referred herein as mixed kinases) have more potent anti-proliferative activity than certain specific kinase inhibitors. Because inhibition of one specific kinase or a specific pathway is not always sufficient to elicit significant clinical response and might lead to rapid resistance, the instant invention encompasses methods comprising the use of a single agent that is capable of targeting more than one kinase or kinase pathway. The methods of the invention therefore comprise methods for affecting processes important for cell survival, proliferation, growth and malignant transformation, motility and invasion leading to angiogenesis and metastasis by simultaneously targeting multiple protein kinases or protein kinase pathways.
The present invention therefore is directed to the use of agents able to target certain kinases, that is, to regulate or to modulate the activity, function or level of certain kinases and/or the level of expression of genes encoding certain kinases, or regulate or modulate certain kinase-mediated signaling pathways; i.e., able to target the kinase or kinase-mediated pathway. Such agents are referred to as “single agents” or “mixed kinase agents.”
Applicants have discerned that CDK kinases, Rsk kinases, checkpoint kinases, MAPK kinases, Src kinases, and the kinases Fes, Lyn, Syk are important to, in particular, the progression of proliferative disorders. In one embodiment, therefore, the agent targets two or more of the following: kinases from the src kinase family, kinases from the Rsk kinase family, kinases from the CDK family, kinases from the MAPK kinase family, and tyrosine kinases such as Fes, Lyn, and Syk kinases. The agent may target two or more kinases of the same family, or may target kinases representing two or more kinase families or classes.
In preferred embodiments, the invention provides a method of treating a disease, disorder or condition comprising targeting multiple kinases or kinase pathways that have been implicated in the disease, disorder, or condition.
The instant invention also encompasses the use of these single agents in combination with one or more agents that specifically target a single kinase or kinase pathway. In other embodiments, the single agent may be used with other therapies such as conventional forms of chemotherapy, antiangiogenics, nucleoside analogs, proteosome inhibitors, and the like; radiation therapy; cytokine therapy; surgery; or any of the other therapies disclosed in Section 5.4.3, below.
As such, the methods of the invention are also useful as an adjunct to existing and/or experimental therapies.
According to the methods of the present invention, identification of modulators that can simultaneously target, regulate or inhibit multiple kinases or kinase pathways critically implicated in various diseases or disorders can be achieved by using the assays disclosed in Examples 4-83, or by using in vivo models described in Example 3.
As used herein, “resistance” and “resistant” refer to target kinases that show detectably reduced response to a particular kinase modulator over time. For example, a resistant kinase is one that shows detectably more activity when exposed at a time after the first exposure to a single agent of the invention, as compared to the response of the kinase upon the first exposure of the kinase to the single agent. Also by way of example, a kinase may be resistant, or show a detectable lessening of response, to a single inhibitor, or a mixture of inhibitors. The resistance of the kinase to a particular modulator may arise from a mutation, change in post-translational modification, upregulation or downregulation of the gene encoding the kinase, increased or decreased clearance of the kinase from tissues, or any other cause. Resistance may also develop as a result of the upregulation of alternate kinase-mediated pathways the function of which is at least partly redundant to the targeted kinase's pathway.
As used herein, the terms “simultaneous” and “simultaneously” mean over the duration of a particular administration and effect of a single agent, where a single agent is administered to an individual, and refer to the effect the therapy has on all targeted kinases, whether or not those effects are demonstrable at the same particular point in time during the course of administration and effect. A particular single agent, combination of single agents, or combination of one or more single agents and one or more other compounds target two or more kinases simultaneously over a course of therapy. For example, where a single agent is administered to an individual and an effect on one targeted kinase is detectable immediately (e.g., within the first few minutes after administration), and an effect on a second targeted kinase is detectable only later, the single agent is said to affect the two kinases simultaneously. “Simultaneous” and “simultaneously” also refer to similar effects in vitro resulting from contact with a single agent.
As used herein, “side effect” indicates an effect of a particular single agent, combination of single agents, or combination of single agent(s) with other treatments other than the immediate effect of modulating the activity of (e.g., inhibiting) the two or more kinases targeted.
As used herein, a single agent acts “directly” or “specifically” on two or more target kinases by interacting with each of the kinases to modify, inhibit or regulate the kinases activities, for example, inhibiting the kinase in a competitive, noncompetitive or uncompetitive manner; altering the level of the kinase in a tissue by interacting with transcriptional complexes specific for the kinase; altering the post-translational modification of those specific kinases, and the like. For example, whether a compound directly targets two or more kinases can be determined using the in vitro assays as described herein, or may be determined using other art-known kinase assays. A single agent does not act “directly” on a target kinase where the effect on the target kinase is solely the result of the single agent's effect on a kinase that modifies the target kinase.
As used herein, a “therapeutically effective amount” refers to that amount of the therapeutic agent sufficient to result in a detectable amelioration of one or more symptoms of a disorder. In certain embodiments, a “therapeutically effective amount” refers to that amount of the therapeutic agent sufficient to destroy, modify, control or remove primary, regional or metastatic cancer tissue. As such, therapeutically effective amount also refers to the amount of therapeutic agent sufficient to delay or minimize the spread of cancer. In another example, “therapeutically effective amount” refers to the amount effective to detectably reduce inflammation, or the production of cytokines or proliferation of cells associated with inflammation. A therapeutically effective amount may also refer to the amount of the therapeutic agent that provides a therapeutic benefit in the treatment or management of a disease, condition, or disorder, or to reduce the incidence of recurrence or onset of one or more symptoms of a disease, condition or disorder in a population of individuals.
As used herein, a “prophylactically effective amount” refers to that amount of the prophylactic agent sufficient to result in the prevention of the recurrence or onset of one or more symptoms of a disease, condition, or disorder.
In certain embodiments, a “prophylactically effective amount” refers to that amount of the prophylactic agent sufficient to result in the prevention of the recurrence or spread of cancer. As such, the term also refers to the amount of prophylactic agent sufficient to prevent the recurrence or spread of cancer or the occurrence of cancer in an individual, including but not limited to those individuals predisposed to cancer or previously exposed to carcinogens. A prophylactically effective amount may also refer to the amount of the prophylactic agent that provides a prophylactic benefit in the prevention of a disease, condition, or disorder.
As used herein, the terms “single agent” and “single agents” refer to any therapeutic or prophylactic agent(s) that can be used in the prevention, treatment, management or amelioration of one or more symptoms of a disease, condition, or disorder, wherein the single agent simultaneously targets more than one kinase or kinase pathway. A single agent is preferably not a macromolecule (e.g., protein, polypeptide, polysaccharide, polynucleotide) and is preferably a small organic molecule having a molecular weight of less than 1000 daltons. A single agent may be a peptide or a polynucleotide fragment (e.g., an aptamer). Preferably, the single agent is orally bioavailable and/or bioactive, and is bioactive and bioavailable when delivered, e.g., intramuscularly, intravenously, or by inhalation. The term “single agent” does not include any naturally-occurring protein in its native form.
The terms “agent” or “therapeutic agent” or “prophylactic agent” as used herein refers to any molecule, e.g., protein, polypeptide, peptide, antibody, antibody fragment, oliogonucleotides, antisense oliogonucleotides, large molecule, or small molecule (less than 10 kD) that targets a kinase, that is, modulates, regulates, enhances, blocks, inhibits, reduces or neutralizes the function, activity or expression of a protein kinase.
As used herein, the phrase “non-responsive/refractory” is used to describe patients treated with currently available therapies, wherein the therapy is not clinically adequate to relieve symptoms of the patients such that these patients need additional effective therapy, e.g., remain unsusceptible to therapy. The phrase can also describe patients who respond to therapy yet suffer from side effects, relapse, develop resistance, etc. In connection with anti-cancer therapy, in certain embodiments, “non-responsive/refractory” means that at least some significant portion of the cancer cells are not killed or their cell division arrested. The determination of whether the cancer cells are “non-responsive/refractory” can be made either in vivo or in vitro by any method known in the art for assaying the effectiveness of treatment on cancer cells, using the art-accepted meanings of “refractory” in such a context.
In various embodiments, a cancer is “non-responsive/refractory” where the number of cancer cells has not been significantly reduced, or has increased.
As used herein, the phrase “low tolerance” refers to a state in which the patient suffers from side effects from treatment to the extent that the patient does not benefit from and/or will not continue therapy because of the adverse effects.
As used herein, the terms “individual,” “subject” and “patient” are used interchangeably. As used herein, a subject is preferably a mammal such as a non-primate (e.g., cows, pigs, horses, cats, dogs, rats etc.) or a primate (e.g., monkey and human).
As used herein, the terms “manage,” “managing” and “management” refer to the beneficial effects that a subject derives from a prophylactic or therapeutic agent, which does not result in a cure of the disease. In certain embodiments, a subject is administered one or more prophylactic or therapeutic agents to “manage” a disease so as to prevent the progression or worsening of the disease.

This invention encompasses methods for treating, preventing, or managing conditions, diseases, or disorders involving more than one protein kinase or protein kinase pathway. The present invention is based in part on the discovery that small molecule kinase inhibitors capable of simultaneously inhibiting multiple kinases (also referred herein as mixed kinases) have more potent anti-proliferative activity than certain specific kinase inhibitors. The present inventors have discovered methods for affecting processes important for cell survival, proliferation, growth and malignant transformation, motility and invasion leading to angiogenesis and metastasis by simultaneously modulating protein kinase pathways involving two or more of the following: kinases from the src kinase family, kinases from the Rsk kinase family, kinases from the CDK family, kinases from the MAPK kinase family, and tyrosine kinases such as Fes, Lyn, and Syk kinases.

According to the methods of the present invention, identification of single agents that can simultaneously target, that is, modulate, regulate or inhibit multiple kinases or kinase pathways critically implicated in various diseases or disorders can be achieved by using kinase assays known in the art, for example, the assays described in Examples 4-84, below.
The present invention provides a method of treating an individual having a disease or condition associated with two or more kinases. As used herein, “individual,” “Patient” and the like may be a eukaryote, preferably a mammal, more preferably a human.
In one embodiment, the methods of the invention are useful in treating, managing, or preventing diseases or disorders in patients that have been refractory or resistant to single agents capable of targeting a single specific kinase or kinase pathway. It is also envisioned that the methods of the invention are useful in treating, managing, or preventing diseases or disorders in patients that have undergone, are currently undergoing, or may in the future undergo other treatments. For example, the compounds of the invention may be administered to individuals that have been administered other therapeutic agents, or that have undergone other therapies such as radiation or surgery.

In yet another embodiment, the methods of the invention are useful in treating, managing, or preventing diseases or disorders in patients that have been determined to be pre-disposed to any disease condition, particularly to cancer, obesity, or inflammation-related disorders, or any of the disorders recited in Section 5.2.
The present invention encompasses therapies which involve administering one or more compounds to an animal, preferably a mammal, and most preferably a human, for preventing, treating, or ameliorating symptoms associated with a disease, disorder, or infection, associated with the activity or inactivity of one or more protein kinases. In a preferred embodiment, the invention relates to the prevention, treatment or amelioration of symptoms associated with a disease, disorder or infection, associated with the abnormal activity (e.g., abnormal upregulation or downregulation) of at least two protein kinases, at least three protein kinases, at least four protein kinases, at least five protein kinases, at least ten protein kinases or at least twenty protein kinases. In some embodiments, the methods of the invention are used in combination with one or more therapies such as, but not limited to, chemotherapies, radiation therapies, hormonal therapies, and/or biological therapies/immunotherapies.
The methods of the invention are useful in treating, preventing, managing or ameliorating a variety of diseases or disorders related to protein kinase activity, including, but not limited to, disorders related to the following: gene expression, cytoskeletal integrity, cell adhesion, cell cycle progression, differentiation and metabolism. Such diseases are controlled by the complex interplay of protein kinases and phosphatases, and associated malfunctions of cellular signaling have been linked to many diseases including cancer and diabetes. Sridhar et al., Pharmaceutical Research, 17(11) 1345-1353 (2000). Therapeutic strategies that target protein kinases and therefore regulate signal transduction have become the subject of intense research. For example, protein kinase C and tyrosine kinases have been implicated in certain types of cancer, diabetes and complications associated with diabetes. In addition protein kinase C isoforms have been implicated in cellular changes observed in the vascular complications of diabetes. Sridhar et al., Pharmaceutical Research, 17(11) 1345-1353 (2000); Chalfant et al., Mol. Endocrinol. 10:1273-1281 (1996). As a result of the complexity associated with protein kinase pathways, overlap exists between various protein kinases and a wide range of diseases or disorders. The methods of the invention relate to the treatment, management, prevention or amelioration of diseases associated with a protein kinase including, but not limited to, cancer, inflammatory disorders, diabetes, obesity, angiogenesis disorders and cardiovascular disorders.
In particular, the methods of the invention are useful for the prevention, treatment, management and/or amelioration of various diseases. By way of example, and not meant to limit, examples of the types of classes of disease that can be prevented, treated or managed include, but are not limited to, inflammatory conditions including, but not limited to: diabetes (such as Type II diabetes, Type I diabetes, diabetes insipidus, diabetes mellitus, maturity-onset diabetes, juvenile diabetes, insulin-dependant diabetes, non-insulin dependant diabetes, malnutrition-related diabetes, ketosis-prone diabetes or ketosis-resistant diabetes); nephropathy (such as glomerulonephritis or acute/chronic kidney failure); obesity (such as hereditary obesity, dietary obesity, hormone related obesity or obesity related to the administration of medication); hearing loss (such as that from otitis extema or acute otitis media); fibrosis related diseases (such as pulmonary interstitial fibrosis, renal fibrosis, cystic fibrosis, liver fibrosis, wound-healing or burn-healing, wherein the burn is a first-, second- or third-degree burn and/or a thermal, chemical or electrical burn); arthritis (such as rheumatoid arthritis, rheumatoid spondylitis, osteoarthritis or gout); an allergy; allergic rhinitis; acute respiratory distress syndrome; asthma; bronchitis; an inflammatory bowel disease (such as irritable bowel syndrome, mucous colitis, ulcerative colitis, Crohn's disease, gastritis, esophagitis, pancreatitis or peritonitis); or an autoimmune disease (such as scleroderma, systemic lupus erythematosus, myasthenia gravis, transplant rejection, endotoxin shock, sepsis, psoriasis, eczema, dermatitis or multiple sclerosis).

As described earlier, aberrant kinase activity has been associated with inflammatory disorders as well as with diabetes and its related effects. Sridhar et al., Pharmaceutical Research, 17(11)1345-1353 (2000). Indeed, a number of kinases have been implicated in cellular changes observed in the vascular complications of diabetes. Chalfant et al., Mol. Endocrinol. 10:1273-1281 (1996). Furthermore, as obesity is closely related with the insulin resistance found in type II diabetes, kinases that interfere with insulin action have been implicated in disorders related to obesity as well as diabetes.

In more particular embodiments, the present invention also comprises the administration of one or more single agents in combination with the administration of one or more therapies such as, but not limited to anti-cancer agents such as those disclosed in Table
The invention also encompasses administration of one or more single agents in combination with radiation therapy comprising the use of x-rays, gamma rays and other sources of radiation to destroy the cancer cells. In preferred embodiments, the radiation treatment is administered as external beam radiation or teletherapy wherein the radiation is directed from a remote source. In other preferred embodiments, the radiation treatment is administered as internal therapy or brachytherapy wherein a radioactive source is placed inside the body close to cancer cells or a tumor mass.
Cancer therapies and their dosages, routes of administration and recommended usage are known in the art and have been described in such literature as the Physician's Desk Reference (56th ed., 2002).
To treat inflammations and inflammation-related conditions, administration of one or more single agents may be combined with one or more compounds having anti-inflammatory activity. In various embodiments, therefore, treatment with a single agent may be combined with treatment with, for example, steroidal anti-inflammatory agents, nonsteriodal anti-inflammatory agents (NSAIDs), Benadryl®, IL-9 antagonists, antihistamines, sympthomimetics, glucocorticoids, corticosteroids, β-adrenergic drugs (epinephrine and isoproterenol), theophylline, anticholinergic drugs (e.g., atropine and ipratropium bromide), leukotriene inhibitors, immunotherapies (e.g., repeated long-term injection of allergen, short course desensitization, venom immunotherapy, an effective amount of one or more anti-IgE antibodies and/or one or more mast cell modulators (e.g., a mast cell protease inhibitor, stem cell factor (c-kit ligand) inhibitor, and c-kit receptor inhibitor).
The present invention relates to the administration of one or more compounds, also called single agents, that act to target two or more kinases, or the genes encoding them, simultaneously.
In a preferred embodiment, a single agent is a pharmaceutical composition. Such compositions comprise a prophylactically or therapeutically effective amount of one or more single agents and a pharmaceutically acceptable carrier. In a specific embodiment, the term “pharmaceutically acceptable” means approved by a regulatory agency of the Federal or a state government or listed in the U.S. Pharmacopeia or other generally recognized pharmacopeia for use in animals, and more particularly in humans. The term “carrier” refers to a diluent, adjuvant (e.g., Freund's adjuvant (complete and incomplete)), excipient, or vehicle with which the therapeutic is administered. Such pharmaceutical carriers can be sterile liquids, such as water and oils, including those of petroleum, animal, vegetable or synthetic origin, such as peanut oil, soybean oil, mineral oil, sesame oil and the like. Water is a preferred carrier when the pharmaceutical composition is administered intravenously. Saline solutions and aqueous dextrose and glycerol solutions can also be employed as liquid carriers, particularly for injectable solutions. Suitable pharmaceutical excipients include starch, glucose, lactose, sucrose, gelatin, malt, rice, flour, chalk, silica gel, sodium stearate, glycerol monostearate, talc, sodium chloride, dried skim milk, glycerol, propylene, glycol, water, ethanol and the like. The composition, if desired, can also contain minor amounts of wetting or emulsifying agents, or pH buffering agents. These compositions can take the form of solutions, suspensions, emulsion, tablets, pills, capsules, powders, sustained-release formulations and the like. Oral formulation can include standard carriers such as pharmaceutical grades of mannitol, lactose, starch, magnesium stearate, sodium saccharine, cellulose, magnesium carbonate, etc. Examples of suitable pharmaceutical carriers are described in “Remington's Pharmaceutical Sciences” by E. W. Martin. Such compositions will contain a prophylactically or therapeutically effective amount of a prophylactic or therapeutic agent preferably in purified form, together with a suitable amount of carrier so as to provide the form for proper administration to the patient. The formulation should suit the mode of administration. In a preferred embodiment, the pharmaceutical compositions are sterile and in suitable form for administration to a subject, preferably an animal subject, more preferably a mammalian subject, and most preferably a human subject.
In a specific embodiment, it may be desirable to administer the pharmaceutical compositions of the invention locally to the area in need of treatment; this may be achieved by, for example, and not by way of limitation, local infusion, by injection, or by means of an implant, said implant being of a porous, non-porous, or gelatinous material, including membranes, such as sialastic membranes, or fibers. Preferably, when administering one or more prophylactic or therapeutic agents, care must be taken to use materials to which the prophylactic or therapeutic agents do not absorb.
In another embodiment, the single agent can be delivered in a vesicle, in particular a liposome (see Langer, Science 249:1527-1533 (1990); Treat et al., in Liposomes in the Therapy of Infectious Disease and Cancer, Lopez-Berestein and Fidler (eds.), Liss, N.Y., pp. 353-365 (1989); Lopez-Berestein, ibid., pp. 3 17-327; see generally ibid.).
In yet another embodiment, the single agent can be delivered in a controlled release or sustained release system. In one embodiment, a pump may be used to achieve controlled or sustained release (see Langer, supra; Sefton, 1987, CRC Crit. Ref. Biomed. Eng. 14:20; Buchwald et al., 1980, Surgery 88:507; Saudek et al., 1989, N. Engl. J. Med. 321:574). In another embodiment, polymeric materials can be used to achieve controlled or sustained release of the antibodies of the invention or fragments thereof (see e.g., Medical Applications of Controlled Release, Langer and Wise (eds.), CRC Pres., Boca Raton, Fla. (1974); Controlled Drug Bioavailability, Drug Product Design and Performance, Smolen and Ball (eds.), Wiley, N.Y. (1984); Ranger and Peppas, 1983, J., Macromol. Sci. Rev. Macromol. Chem. 23:61; see also Levy et al., 1985, Science 228:190; During et al., 1989, Ann. Neurol. 25:351; Howard et al., 1989, J. Neurosurg. 7 1:105); U.S. Pat. No. 5,679,377; U.S. Pat. No. 5,916,597; U.S. Pat. No. 5,912,015; U.S. Pat. No. 5,989,463; U.S. Pat. No. 5,128,326; PCT Publication No. WO 99/15154; and PCT Publication No. WO 99/20253. Examples of polymers used in sustained release formulations include, but are not limited to, poly(2-hydroxy ethyl methacrylate), poly(methyl methacrylate), poly(acrylic acid), poly(ethylene-co-vinyl acetate), poly(methacrylic acid), polyglycolides (PLG), polyanhydrides, poly(N-vinyl pyrrolidone), poly(vinyl alcohol), polyacrylamide, poly(ethylene glycol), polylactides (PLA), poly(lactide-co-glycolides) (PLGA), and polyorthoesters. In a preferred embodiment, the polymer used in a sustained release formulation is inert, free of leachable impurities, stable on storage, sterile, and biodegradable. In yet another embodiment, a controlled or sustained release system can be placed in proximity of the therapeutic target, i.e., the lungs, thus requiring only a fraction of the systemic dose (see, e.g., Goodson, in Medical Applications of Controlled Release, supra, vol. 2, pp. 115-138 (1984)).
Controlled release systems are discussed in the review by Langer (1990, Science 249:1527-1533). Any technique known to one of skill in the art can be used to produce sustained release formulations comprising one or more antibodies of the invention or fragments thereof. See e.g., U.S. Pat. No. 4,526,938, PCT publication WO 91/05548, PCT publication WO 96/20698.Ning et al., 1996, “Intratumoral Radioimmunotheraphy of a Human Colon Cancer Xenograft Using a Sustained-Release Gel,” Radiotherapy & Oncology 39:179-189, Song et al., 1995, “Antibody Mediated Lung Targeting of Long-Circulating Emulsions,” PDA Journal of Pharmaceutical Science & Technology 50:372-397, Cleek et al., 1997, “Biodegradable Polymeric Carriers for a bFGF Antibody for Cardiovascular Application,” Pro. Int'l. Symp. Control Rel. Bioact. Mater. 24:853-854, and Lam et al., 1997, “Microencapsulation of Recombinant Humanized Monoclonal Antibody for Local Delivery,” Proc. Int'l. Symp. Control Rel. Bioact. Mater. 24:759-760, each of which is incorporated herein by reference in their entirety. (0161] In a specific embodiment where the single agent of the invention is one or more nucleic acid molecules encoding one or more prophylactic or therapeutic agents, the nucleic acid can be administered in vivo to promote expression of its encoded prophylactic or therapeutic agents, by constructing it as part of an appropriate nucleic acid expression vector and administering it so that it becomes intracellular, e.g., by use of a retroviral vector (see U.S. Pat. No. 4,980,286), or by direct injection, or by use of microparticle bombardment (e.g., a gene gun; Biolistic, Dupont), or coating with lipids or cell-surface receptors or transfecting agents, or by administering it in linkage to a homeobox-like peptide which is known to enter the nucleus (see e.g., Joliot et al., 1991, Proc. Natl. Acad. Sci. USA 88:1864-1868), etc. Alternatively, a nucleic acid can be introduced intracellularly and incorporated within host cell DNA for expression by homologous recombination.
A pharmaceutical composition of the invention is formulated to be compatible with its intended route of administration. Examples of routes of administration include, but are not limited to, parenteral, e.g., intravenous, intradermal, subcutaneous, oral (e.g., inhalation), intranasal, transdermal (topical), transmucosal, and rectal administration. In a specific embodiment, the composition is formulated in accordance with routine procedures as a pharmaceutical composition adapted for intravenous, subcutaneous, intramuscular, oral, intranasal or topical administration to human beings. In a preferred embodiment, a pharmaceutical composition is formulated in accordance with routine procedures for subcutaneous administration to human beings. Typically, compositions for intravenous administration are solutions in sterile isotonic aqueous buffer. Where necessary, the composition may also include a solubilizing agent and a local anesthetic such as lignocaine to ease pain at the site of the injection.
If the single agent is to be administered topically, it can be formulated in the form of, e.g., an ointment, cream, transdermal patch, lotion, gel, shampoo, spray, aerosol, solution, emulsion, or other form well-known to one of skill in the art. See e.g., Remington's Pharmaceutical Sciences and Introduction to Pharmaceutical Dosage Forms, 4th ed., Lea & Febiger, Philadelphia, Pa. (1985). For non-sprayable topical dosage forms, viscous to semi-solid or solid forms comprising a carrier or one or more excipients compatible with topical application and having a dynamic viscosity preferably greater than water are typically employed. Suitable formulations include, without limitation, solutions, suspensions, emulsions, creams, ointments, powders, liniments, salves, and the like, which are, if desired, sterilized or mixed with auxiliary agents (e.g., preservatives, stabilizers, wetting agents, buffers, or salts) for influencing various properties, such as, for example, osmotic pressure. Other suitable topical dosage forms include sprayable aerosol preparations wherein the active ingredient, preferably in combination with a solid or liquid inert carrier, is packaged in a mixture with a pressurized volatile (e.g., a gaseous propellant, such as freon), or in a squeeze bottle. Moisturizers or humectants can also be added to pharmaceutical compositions and dosage forms if desired. Examples of such additional ingredients are well-known in the art.
If the compositions of the invention are to be administered intranasally, the compositions can be formulated in an aerosol form, spray, mist or in the form of drops. In particular, prophylactic or therapeutic agents for use according to the present invention can be conveniently delivered in the form of an aerosol spray presentation from pressurized packs or a nebuliser, with the use of a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide or other suitable gas. In the case of a pressurized aerosol the dosage unit may be determined by providing a valve to deliver a metered amount. Capsules and cartridges of, e.g., gelatin for use in an inhaler or insufflator may be formulated containing a powder mix of the compound and a suitable powder base such as lactose or starch.
If the compositions of the invention are to be administered orally, the compositions can be formulated orally in the form of, e.g., tablets, capsules, cachets, gelcaps, solutions, suspensions and the like. Tablets or capsules can be prepared by conventional means with pharmaceutically acceptable excipients such as binding agents (e.g., pregelatinised maize starch, polyvinylpyrrolidone or hydroxypropyl methylcellulose); fillers (e.g., lactose, microcrystalline cellulose or calcium hydrogen phosphate); lubricants (e.g., magnesium stearate, talc or silica); disintegrants (e.g., potato starch or sodium starch glycolate); or wetting agents (e.g., sodium lauryl sulphate). The tablets may be coated by methods well-known in the art. Liquid preparations for oral administration may take the form of, for example, solutions, syrups or suspensions, or they may be presented as a dry product for constitution with water or other suitable vehicle before use. Such liquid preparations may be prepared by conventional means with pharmaceutically acceptable additives such as suspending agents (e.g., sorbitol syrup, cellulose derivatives or hydrogenated edible fats); emulsifying agents (e.g., lecithin or acacia); non-aqueous vehicles (e.g., almond oil, oily esters, ethyl alcohol or fractionated vegetable oils); and preservatives (e.g., methyl or propyl-p-hydroxybenzoates or sorbic acid). The preparations may also contain buffer salts, flavoring, coloring and sweetening agents as appropriate. Preparations for oral administration may be suitably formulated for slow release, controlled release or sustained release of a prophylactic or therapeutic agent(s).
The compositions of the invention may be formulated for parenteral administration by injection, e.g., by bolus injection or continuous infusion. Formulations for injection may be presented in unit dosage form, e.g., in ampoules or in multi-dose containers, with an added preservative. The compositions may take such forms as suspensions, solutions or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents. Alternatively, the active ingredient may be in powder form for constitution with a suitable vehicle, e.g., sterile pyrogen-free water, before use.
The compositions of the invention may also be formulated in rectal compositions such as suppositories or retention enemas, e.g., containing conventional suppository bases such as cocoa butter or other glycerides.
In addition to the formulations described previously, the compositions of the invention may also be formulated as a depot preparation. Such long acting formulations may be administered by implantation (for example subcutaneously or intramuscularly) or by intramuscular injection. Thus, for example, the compositions may be formulated with suitable polymeric or hydrophobic materials (for example as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt.
The compositions of the invention can be formulated as neutral or salt forms. Pharmaceutically acceptable salts include those formed with anions such as those derived from hydrochloric, phosphoric, acetic, oxalic, tartaric acids, etc., and those formed with cations such as those derived from sodium, potassium, ammonium, calcium, ferric hydroxides, isopropylamine, triethylamine, 2-ethylamino ethanol, histidine, procaine, etc.
Generally, the ingredients of compositions of the invention are supplied either separately or mixed together in unit dosage form, for example, as a dry lyophilized powder or water free concentrate in a hermetically sealed container such as an ampoule or sachette indicating the quantity of active agent. Where the composition is to be administered by infusion, it can be dispensed with an infusion bottle containing sterile pharmaceutical grade water or saline. Where the composition is administered by injection, an ampoule of sterile water for injection or saline can be provided so that the ingredients may be mixed prior to administration.
In particular, the invention provides that one or more of the prophylactic or therapeutic agents, or pharmaceutical compositions of the invention is packaged in a hermetically sealed container such as an ampoule or sachette indicating the quantity of the agent. In one embodiment, one or more of the prophylactic or therapeutic agents, or pharmaceutical compositions of the invention is supplied as a dry sterilized lyophilized powder or water free concentrate in a hermetically sealed container and can be reconstituted, e.g., with water or saline to the appropriate concentration for administration to a subject. Preferably, one or more of the prophylactic or therapeutic agents, or pharmaceutical compositions of the invention is supplied as a dry sterile lyophilized powder in a hermetically sealed container at a unit dosage of at least 5 mg, more preferably at least 10 mg, at least 15 mg, at least 25 mg, at least 35 mg, at least 45 mg, at least 50 mg, at least 75 mg, or at least 100 mg. The lyophilized prophylactic or therapeutic agents, or pharmaceutical compositions of the invention should be stored at between 2 and 8° C. in its original container and the prophylactic or therapeutic agents, or pharmaceutical compositions of the invention should be administered within 1 week, preferably within 5 days, within 72 hours, within 48 hours, within 24 hours, within 12 hours, within 6 hours, within 5 hours, within 3 hours, or within 1 hour after being reconstituted. In an alternative embodiment, one or more of the prophylactic or therapeutic agents, or pharmaceutical compositions of the invention is supplied in liquid form in a hermetically sealed container indicating the quantity and concentration of the agent. Preferably, the liquid form of the administered composition is supplied in a hermetically sealed container at least 0.25 mg/ml, more preferably at least 0.5 mg/ml, at least 1 mg/ml, at least 2.5 mg/ml, at least 5 mg/ml, at least 8 mg/ml, at least 10 mg/ml, at least 15 mg/kg, at least 25 mg/ml, at least 50 mg/ml, at least 75 mg/ml or at least 100 mg/ml. The liquid form should be stored at between 2° C. and 8° C. in its original container.
The single agent may, if desired, be presented in a pack or dispenser device that may contain one or more unit dosage forms containing the active ingredient. The pack may for example comprise metal or plastic foil, such as a blister pack. The pack or dispenser device may be accompanied by instructions for administration.
Six compounds (presumptive single agents) were tested against a panel of 50 kinases. The results are presented in Table 2; numbers for each kinase indicate the percent of control kinase activity in the presence of a 3μM concentration of the indicated agent.
ND: Not done
Compounds CC001, CC002 and CC004 were the most active against the kinases tested, inhibiting the kinase activity of 16, 29 and 16 kinases listed in Table 2, respectively, by more than 95% in each case compared to a no-compound control. CC004 showed good inhibitory activity against CDKl and CDK2, MEK1 and Rsk1, and somewhat less inhibitory activity against the Src family kinases cSrc and Yes. CC006 (5-(5-Cyclopentyl-1H-[1,2,4]triazol-3-yl)-3-(4-fluoro-phenyl)-1H-indazole) and CC007 (3-(5-(1H-1,2,4-triazol-3-yl)(1H-indazol-3-yl))phenyl-N-cyclopentylcarboxamide) were included as controls.
CC001 is a low molecular weight mixed kinase inhibitor (MKI) with potent in vitro inhibitory activity against a variety of kinases. CC001 inhibited the activation of kinases and their downstream targets in HCT-116 colon cancer cells in a concentration-dependent manner. CC001 also showed potent antiproliferative activity against a broad spectrum of cancer cell lines, including: non-small cell lung (NSCLC); colon; pancreatic; head and neck; and breast and ovarian cancers. In each case, IC50 values lay in the nanomolar range. In in vitro combination studies with standard chemotherapeutic agents such as taxol, and novel signal transduction inhibitors, CC001 showed additive and/or synergistic antiproliferative activity.
CC001 shows cancer inhibitory effect in in vivo cancer models. SCID mice bearing colon and lung tumors were treated with CC001 at a concentration of 10 mg/kg to 20mg/kg, administered twice a day. CC001 inhibited tumor growth in a dose-dependent manner as a single agent (T/C ratio: 40-60%).
A similar study was performed using an NCI-H460 NSCLC xenograft model in which CC001 was combined with the maximum tolerated dose of Taxotere (an anti-cancer compound related to taxol). In this experiment, a T/C ratio of 16-28% was observed. No apparent additional toxicity as evidenced by weight loss was observed. Additive in vivo effects were also observed with Camptosar (anti-cancer agent generally used for colorectal cancers), with a T/C ratio approaching 15%.
In one experiment, female CB.17 SCID mice were inoculated subcutaneously in the right hind limb with 2×106 HCT-116 cells. After 8 days mice were selected for tumors generally between 75 and 125 mm3 in size and randomly dispersed into groups. Treatment commenced on day 8 and proceeded for the duration of the study. All the compound treatments were given i.p. in a vehicle NPS in a volume of 5 ml/kg. CC001 was administered at 20 mg/kg b.i.d. Camptosar was given as i.p q4d. The tumor volumes were measured twice a week using calipers. Values are mean±SEM. Statistical analysis was performed using ANOVA. As shown in

eP values vs. vehicle control <0.001 (ANOVA)
In a related experiment, two compounds, designated CC002 and CC003, were tested. CC003 is a naphthalene-containing indazole. Female CB.17 SCID mice were inoculated subcutaneously in the right hind limb with 2×106 HCT-116 cells. After 8 days mice were selected for tumors generally between 75 and 125 mm3 in size and randomly dispersed into groups. Treatment commenced on day 8 and proceeded for the duration of the study. All the treatments were given i.p. in a vehicle NPS in a volume of 5 ml/kg. CC002 and CC003 administered at 20 mg/kg b.i.d. for first 4 days (day 8-11 and then switched to qd. Camptosar was given at 25 mg/kg q4d. The tumor volumes were measured twice a week using calipers. Values are mean±SEM. Statistical analysis was performed using ANOVA. As shown in

bMean (mm3) ± SEM
cRatio of mean tumor volume for treated vs. vehicle control
ddays to reach tumors to reach 1000 mm3

Compound C001 shows increased effect when administered with a second compound. Female CB.17 SCID mice were inoculated subcutaneously in the right hind limb with 2×106 HCT-116 cells. After 8 days mice were selected for tumors generally between 75 and 125 mm3 in size and randomly dispersed into groups. Treatment commenced on day 8 and proceeded for the duration of the study. All the compound treatments were given i.p. in a vehicle NPS in a volume of 5 ml/kg. CC001 was administered at 20 mg/kg b.i.d. Camptosar was given as i.p q4d. The tumor volumes were measured twice a week using calipers. Values are mean±SEM. Statistical analysis was performed using ANOVA. As shown in

Single agents may be confirmed or finally identified using a variety of in vivo models. Candidate single agents are typically first identified in in vitro screens, and confirmed in in vivo models for the particular disease condition under study.
First, a suitable in vivo model is selected. For example, mouse tumor models are available for many types of cancers, including cancers with specific metastasis patterns, and can be selected from known sources such as the Mouse Tumor Biology Database Project (MTBDP), which acts as a clearinghouse for information on mouse tumor models available. The MTBDP is available on the internet at tumor.informaticsjax.org/FMPro?-db=TumorInstance&-format=mtdp.html&-view. Mouse inflammation and diabetes models are available from, for example, The Jackson Laboratory (Bar Harbor, Me.) under the name Jax Mice & Services; see jax.org/jaxmice and jaxmice.jax.org/jaxmicedb/html/sbmodel—7.shtml, respectively. Other disease models, in mice or in other mammals, may be used, as well. For example, mouse, hamster or rat models for arthritis and obesity are known.
As a second example, the anti-inflammatory activity of a presumptive single agent may be assessed using a carrageenan-induced arthritis rat model. Carrageenan-induced arthritis has also been used in rabbit, dog and pig in studies of chronic arthritis or inflammation. Quantitative histomorphometric assessment is used to determine therapeutic efficacy. The methods for using such a carrageenan-induced arthritis model is described in Hansra P. et al., “Carrageenan-Induced Arthritis in the Rat,” Inflammation, 24(2): 141-155, (2000). Also commonly used are zymosan-induced inflammation animal models as known and described in the art. The anti-inflammatory activity of presumptive single agent can also be assessed by measuring the inhibition of carrageenan-induced paw edema in the rat, using a modification of the method described in Winter C. A. et al., “Carrageenan-Induced Edema in Hind Paw of the Rat as an Assay for Anti-inflammatory Drugs” Proc. Soc. Exp. Biol Med. 111, 544-547 (1962). This assay has been used as a primary in vivo screen for the anti-inflammatory activity of most NSAIDs, and is considered predictive of human efficacy. The anti-inflammatory activity of the test presumptive single agent is expressed as the percent inhibition of the increase in hind paw weight of the test group relative to the vehicle dosed control group.
Animal models for asthma can also be used to assess the efficacy of a presumptive single agent. see, e.g., Cohn et al., 1997, J. Exp. Med. 1861737-1747).
Animal models for autoimmune disorders can also be used to assess the efficacy of a presumptive single agent. Animal models for autoimmune disorders such as type 1 diabetes, thyroid autoimmunity, systemic lupus erythematosus, and glomerulonephritis have been developed (Flanders et al., 1999, Autoimmunity 29:235-246; Krogh et al., 1999, Biochimie 81:511-515; Foster, 1999, Semin. Nephrol. 19:12-24).
Alternatively, in vivo models may be created. For example, tumor models may be created by administration of specific tumor cells to mice. As an example, a colon carcinoma model may be constructed as follows. MCA26 is a tumor cell line of chemically induced colon carcinoma in BALB/c mouse (Corbett et al., 1975). Metastatic colon cancer is induced by implanting approximately 7×104 MCA26 cells into the left lobe of the liver of 8-10 week old female BALB/c mice (Taconic). At day 7, mice with 5×5 mm2 size tumors are selected for administration of the presumptive single agent. Alternatively, cells may be administered intraperitoneally or through the tail vein.
Once the model is selected, specific kinases are identified as potential targets. For example, for tumor models, appropriate kinases to target may be those known to be involved in cell cycle control, attachment signaling, or angiogenesis. Kinases with unknown, or poorly-characterized, roles in a particular disease condition may also be tested; however, where this is the case, any inhibition or modulation of kinase activity must be correlated with the appropriate and desired response (e.g., reduction in proliferation).
Particular compounds (i. e., presumptive single agents) are then tested for their ability to affect the disease condition under study. The agent to be tested is administered to the subject animal, and the physiological response of the disease condition is compared to a control (typically an animal to which is administered only the carrier for the agent). Criteria for efficacy depend upon the disease condition under consideration. For example, typical efficacy criteria for tumor models is a reduction in apparent weight loss, reduction or lack of increase in tumor size; reduction in metastasis; decreased numbers of abnormal cells in tissue slices, and the like. Criteria may be subjective, such as an apparent improvement in appearance or health, or objective, in which case the difference(s) between control and experimental groups is typically statistically determined. Kinase activities, and changes in activities, can be determined by taking blood or tissue samples by standard means, and testing kinase activity using one or more of the example assays provided in Examples 4 to 83.
Single agents are identified in such in vivo assays as agents that affect two or more kinases, and have at least one beneficial effect on the disease condition under study.
Examples 4-83: Assays for measuring activity of candidates: The following assays may be used to assess kinase activity; the assays are modified in the experimental condition by the addition of a compound to be tested for kinase inhibitory or modulatory activity. These example assays are not meant to be exclusive; the activity of various kinases may be assessed by other methods, as well.

Cyclin-dependent kinase activity can be measured by quantifying the enzyme-catalyzed, time-dependent incorporation of radioactive phosphate from [32P]ATP or [33P]ATP into a protein substrate. Unless noted otherwise, assays are performed in 96-well plates in a total volume of 50 μL, in the presence of 10 mM HEPES (N-[2-hydroxyethyl]piperazine-N′-[2-ethanesulfonic acid]) (pH 7.4), 10 mM MgCl2, 25 μM adenosine triphosphate (ATP), 1 mg/mL ovalbumin, 5 μg/mL leupeptin, 1 mM dithiothreitol, 10 mM beta-glycerophosphate, 0.1 mM sodium vanadate, 1 mM sodium fluoride, 2.5 mM ethylene glycol-bis(β-aminoethyl ethKer)-N,N,N′N′-tetraacetic acid (EGTA), 2% (v/v) dimethylsulfoxide, and 0.03-0.4 μCi [32/33P]ATP per reaction. Reactions are initiated with appropriate enzyme, incubated at 30° C., and terminated after 20 minutes by the addition of ethylenediaminetetraacetic acid (EDTA) to 250 mM. The phosphorylated substrate is then captured on a nitrocellulose or phosphocellulose membrane using a 96-well filtration manifold, and unincorporated radioactivity is removed by repeated washing with 0.85% phosphoric acid. Radioactivity is quantified by exposing the dried membranes to a phosphorimager.
Apparent Ki values are measured by assaying enzyme activity in the presence of different inhibitor compound concentrations and subtracting the background radioactivity measured in the absence of enzyme. Inhibition data are fit to an equation for competitive inhibition using Kaleidagraph (Synergy Software), or are fit to an equation for competitive tight-binding inhibition using the software KineTic (BioKin, Ltd.).
A complex of human CDK4 and cyclin D3, or a complex of human CDK4 and genetically truncated (1-264) cyclin D3, is purified using traditional biochemical chromatographic techniques from insect cells that had been co-infected with the corresponding baculovirus expression vectors (see e.g., Meijer and Kim, “Chemical Inhibitors of Cyclin-Dependent Kinases,” Methods in Enzymol., vol. 283 (1997), pp. 113-128). The enzyme complex (5 or 50 nM) is assayed with 0.3-0.5 μg of purified recombinant retinoblastoma protein fragment (Rb) as a substrate. The engineered Rb fragment (residues 386-928 of the native retinoblastoma protein; 62.3 kDa) contains the majority of the phosphorylation sites found in the native 106-kDa protein, as well as a tag of six histidine residues for ease of purification. Phosphorylated Rb substrate is captured by microfiltration on a nitrocellulose membrane and quantified using a phosphorimager as described above. For measurement of tight-binding inhibitors, the enzyme complex concentration is lowered to 5 nM, and the assay duration is extended to 60 minutes, during which the time-dependence of product formation is linear.
CDK2 is purified using the methodology described in Rosenblatt et al., “Purification and Crystallization of Human Cyclin-dependent Kinase 2, ” J. Mol. Biol., vol. 230, 1993, pp. 1317-1319. Cyclin A is purified from E. coli cells expressing full-length recombinant cyclin A, and a truncated cyclin A construct is generated by limited proteolysis and purified as described in Jeffrey et al., “Mechanism of CDK activation revealed by the structure of a cyclin A-CDK2 complex,” Nature, vol. 376 (Jul. 27, 1995), pp. 313-320. A complex of CDK2 and proteolyzed cyclin A is prepared and purified by gel filtration. The substrate for this assay is the same Rb substrate fragment used for the CDK4 assays, and the methodology of the CDK2/cyclin A and the CDK4/cyclin D3 assays is essentially the same, except that CDK2 is present at 150 nM or 5 nM. Ki values are measured as described above.
The stimulation of cell proliferation by growth factors such as VEGF and others is dependent upon their induction of autophosphorylation of each of their respective receptor's tyrosine kinases. Therefore, the ability of a protein kinase inhibitor to block cellular proliferation induced by these growth factors is directly correlated with its ability to block receptor autophosphorylation. To measure the protein kinase inhibition activity of the compounds, the following constructs are used.
VEGF-R2 Construct for Assay: This construct determines the ability of a test compound to inhibit tyrosine kinase activity. A construct (VEGF-R2Δ50) of the cytosolic domain of human vascular endothelial growth factor receptor 2 (VEGF-R2) lacking the 50 central residues of the 68 residues of the kinase insert domain is expressed in a baculovirus/insect cell system. Of the 1356 residues of full-length VEGF-R2, VEGF-R2Δ50 contains residues 806-939 and 990-1171, and also one point mutation (E990V) within the kinase insert domain relative to wild-type VEGF-R2. Autophosphorylation of the purified construct is performed by incubation of the enzyme at a concentration of 4 μM in the presence of 3 mM ATP and 50 mM MgCl2 in 100 mM Hepes, pH 7.5, containing 5% glycerol and 5 mM DTT, at 4° C. for 2 hours. After autophosphorylation, this construct has been shown to possess catalytic activity essentially equivalent to the wild-type autophosphorylated kinase domain construct. See Parast et al., Biochemistry, 37, 16788-16801(1998).
CHK1 Construct for Assay: C-terminally His-tagged full-length human CHK1 (FL-CHK1) is expressed using the baculovirus/insect cell system. It contains 6 histidine residues (6×His-tag) at the C-terminus of the 476 amino acid human CHK1. The protein is purified by conventional chromatographic techniques.
VEGF-R2 Assay—Coupled Spectrophotometric (FLVK-P) Assay: The production of ADP from ATP that accompanies phosphoryl transfer is coupled to oxidation of NADH using phosphoenolpyruvate (PEP) and a system having pyruvate kinase (PK) and lactic dehydrogenase (LDH). The oxidation of NADH can be monitored by following the decrease of absorbance at 340 nm (e340=6.22 cm−1 mM−1) using a Beckman DU 650 spectrophotometer. Assay conditions for phosphorylated VEGF-R2Δ50 (indicated as FLVK-P in the tables below) are as follows: 1 mM PEP; 250 μM NADH; 50 units of LDH/mL; 20 units of PK/mL; 5 mM DTT; 5.1 mM poly(E4Y1); 1 mM ATP; and 25 mM MgCl2 in 200 mM Hepes, pH. 7.5. Assay conditions for unphosphorylated VEGF-R2Δ50 (indicated as FLVK in the tables) are as follows: 1 mM PEP; 250 μM NADH; 50 units of LDH/mL; 20 units of PK/mL; 5 mM DTT; 20 mM poly(E4Y1); 3 mM ATP; and 60 mM MgCl2 and 2 mM MnCl2 in 200 mM Hepes, pH 7.5. Assays are initiated with 5 to 40 nM of enzyme. Ki values are determined by measuring enzyme activity in the presence of varying concentrations of test compounds. The data are analyzed using Enzyme Kinetic and Kaleidagraph software.
The production of ADP from ATP that accompanies phosphoryl transfer to the synthetic substrate peptide Syntide-2 (PLARTLSVAGLPGKK; SEQ ID NO:1) is coupled to oxidation of NADH using phosphoenolpyruvate (PEP) through the actions of pyruvate kinase (PK) and lactic dehydrogenase (LDH). The oxidation of NADH can be monitored by following the decrease of absorbance at 340 nm (ε340-6.22 cm−1 mM−1) using a HP8452 spectrophotometer. Typical reaction solutions contain: 4 mN PEP; 0.15 mM NADH; 28 units of LDH/ml; 16 units of PK/ml; 3 mM DTT; 0.125 mM Syntide-2; 0.15 mM ATP; 25 mM MgCl2 in 50 mM TRIS, pH 7.5; and 400 mM NaCl. Assays are initiated with 10 nM of FL-CHK1. Ki values are determined by measuring initial enzyme activity in the presence of varying concentrations of test compounds. The data are analyzed using Enzyme Kinetic and Kaleidagraph software.
Cloning, expression and purification of the cytosolic domain of FGFR1 tyrosine kinase (amino acids 456-766) containing three amino acid substitutions (L457V, C488A, and C84S) can be conducted as described in Mohammadi, M. Schlessinger, J., & Hubbard, S. R. (1996) Cell 86, 577-587. This domain is expressed in Sf9 insect cells using a baculovirus expression vector, and protein is purified using conventional techniques. The LCK tyrosine kinase is expressed in insect cells as an N-terminal deletion starting from amino acid 223 to the end of the protein at amino acid 509. The N-terminus of the protein also had two amino acid substitutions, P223M and c 224D. Kinases are purified using conventional chromatographic methods.
Tyrosine kinase activity can be measured using a coupled, continuous spectrophotometric assay, in which production of phosphorylated poly(Glu, Tyr; 4:1) substrate and ADP is coupled to the pyruvate kinase-catalyzed transfer of a phosphate from phosphoenolpyruvate to ADP, with generation of pyruvate and regeneration of ATP. Pyruvate production is in turn coupled to the lactate dehydrogenase-catalyzed reduction of pyruvate to form lactate, with concomitant conversion of NADH to NAD+. Loss of NADH is monitored by measuring absorbance at 340 nm (see e.g., Technikova-Dobrova et al., “Spectrophotometric determination of finctional characteristics of protein kinases with coupled enzymatic assay,” FEBS Letters, vol. 292 (1991), pp. 69-72). Enzyme activity is measured in the presence of 200 mM HEPES (pH 7.5), 2 mM phosphoenolpyruvate, 0.3 mM NADH, 20 mM MgCl2, 100 μM ATP, 5 mM DTT, 5.1 or 25 mM poly (Glu, Tyr) 4:1 for P-FGF or P-LCK assays, respectively, and 15 units/mL each of pyruvate kinase and lactate dehydrogenase. Phosphorylated FGF receptor kinase is present at 100 nM and phosphorylated LCK kinase is present at 50 nM. Assays are performed under initial rate conditions at 37° C., and rates are corrected for any background rate measured in the absence of enzyme. Percent inhibition is calculated relative to control enzyme assayed in the presence of 2% (v/v) DMSO.
Inhibition of various kinases was monitored by examining the transfer of phosphate to an appropriate peptide substrate for each kinase.
Activities for Jnk1, Jnk2, Jnk3, IKK1, IKK2EE, p38a, p38p, MKK3, MKK4, MKK6, MKK7, cdk2/E, cdk2/A, PKCα, ERK and PKA were monitored by the transfer of radio-labeled phosphate from ATP(γSSP) to a protein substrate, and precipitation of the product using trichloroacetic acid. ATP was at 3 times the Km for the relevant kinase. Activities for Akt1, Akt2, and SGK were monitored by the transfer of radio-labeled phosphate from ATP to a specific substrate peptide and capture of the peptide on P81 charged filter paper. ATP was at the Km for the relevant kinase. Activities for IRTK, Abl, and SRC were monitored by transfer of phosphate from ATP to a biotinylated peptide substrate and detection of the phosphorylated peptide using the LANCE technology (Perkin Elmer). ATP was at 3 times the Km for the relevant kinase.
