Description

Patents Form No. 5 N.Z. No. 629860 NEW ZEALAND Patents Act 1953 TE SPECIFICATION METHODS FOR NG CANCER USING TOR KINASE INHIBITOR COMBINATION THERAPY We, Signal Pharmaceuticals, LLC, a United States company of 10300 Campus Point Drive, Suite 100, San Diego, CA 92121, UNITED STATES OF AMERICA do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- (followed by page 1A) METHODS FOR TREATING CANCER USING TOR KINASE INHIBITOR COMBINATION THERAPY 1. FIELD Provided herein are methods for ng or preventing a cancer comprising administering an effective amount of a TOR kinase inhibitor and an effective amount of a second active agent to a patient having a . 2. BACKGROUND The connection n abnormal n phosphorylation and the cause or uence of diseases has been known for over 20 years. ingly, protein kinases have become a very important group of drug s. See Cohen, Nature, 1:309-315 . Various protein kinase inhibitors have been used clinically in the treatment of a wide variety of diseases, such as cancer and chronic matory diseases, including diabetes and stroke. See Cohen, Eur. J. Biochem., 268:5001-5010 (2001), Protein Kinase Inhibitors for the Treatment of Disease: The Promise and the Problems, Handbook of Experimental Pharmacology, Springer Berlin Heidelberg, 167 (2005).
The protein s 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 ve regulatory effects, depending upon their target protein. Protein kinases are involved in specific signaling ys 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 es. 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 lated 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).
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 ated with numerous e ions such as but not limited to cancer, inflammatory diseases, abnormal angiogenesis and diseases related thereto, atherosclerosis, macular degeneration, diabetes, obesity, and pain.
Protein s have become attractive s for the treatment of cancers.
Fabbro et al., Pharmacology & Therapeutics 98 (2002). It has been ed that the involvement of protein kinases in the development of human malignancies may occur by: (1) genomic rearrangements (e.g., BCR-ABL in c 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 bute to the pment and maintenance of the neoplastic phenotype. Fabbro et al., Pharmacology & Therapeutics 93:79-98 (2002).
The elucidation of the intricacy of protein kinase pathways and the complexity of the relationship and interaction among and n the various protein kinases and kinase pathways highlights the importance of developing pharmaceutical agents capable of acting as n kinase modulators, regulators or tors that have cial activity on multiple kinases or le kinase pathways. Accordingly, there remains a need for new kinase modulators.
The protein named mTOR (mammalian target of rapamycin), which is also called FRAP, RAFTI or RAPT1), is a 2549-amino acid Ser/Thr protein kinase, that has been shown to be one of the most critical proteins in the mTOR/PI3K/Akt pathway that regulates cell growth and proliferation. Georgakis and Younes Expert Rev. Anticancer Ther. 6(1):131-140 (2006). mTOR exists within two complexes, mTORC1 and mTORC2. While mTORC1 is sensitive to rapamycin analogs (such as temsirolimus or everolimus), mTORC2 is largely rapamycininsensitive.
Notably, rapamycin is not a TOR kinase inhibitor. Several mTOR inhibitors have been or are being evaluated in clinical trials for the treatment of cancer. Temsirolimus was ed for use in renal cell carcinoma in 2007 and sirolimus was approved in 1999 for the prophylaxis of renal transplant rejection. Everolimus was approved in 2009 for renal cell carcinoma patients that have progressed on vascular endothelial growth factor receptor inhibitors, in 2010 for subependymal giant cell astrocytoma (SEGA) associated with us sclerosis (TS) in patients who require therapy but are not candidates for surgical resection, and in 2011 for progressive neuroendocrine tumors of pancreatic origin (PNET) in ts with unresectable, locally advanced or metastatic disease. There remains a need for TOR kinase inhibitors that inhibit both mTORC1 and mTORC2 xes.
DNA-dependent protein kinase K) is a serine/threonine kinase ed in the repair of DNA double strand breaks (DSBs). DSBs are considered to be the most lethal DNA lesion and occur endogenously or in response to ionizing radiation and chemotherapeutics (for review see Jackson, S. P., Bartek, J. The DNA-damage response in human biology and disease. Nature Rev 2009; 461:1071-1078). If left unrepaired, DSBs will lead to cell cycle arrest and/or cell death (Hoeijmakers, J. H. J. Genome nance mechanisms for preventing cancer. Nature 2001; 411: 366-374; van Gent, D. C., Hoeijmakers, J. H., Kanaar, R.
Chromosomal stability and the DNA double-stranded break connection. Nat Rev Genet 2001; 2: 196-206). In response to the insult, cells have developed complex mechanisms to repair such breaks and these mechanisms may form the basis of therapeutic resistance. There are two major pathways used to repair DSBs, mologous end g (NHEJ) and homologous recombination (HR). NHEJ brings broken ends of the DNA together and rejoins them without reference to a second template (Collis, S. J., DeWeese, T. L., Jeggo P. A., Parker, A.R. The life and death of DNA-PK. Oncogene 2005; 24: 949-961). In contrast, HR is dependent on the proximity of the sister chromatid which provides a template to mediate faithful repair (Takata, M., Sasaki, M. S., Sonoda, E., Morrison, C., Hashimoto, M., Utsumi, H., et al. Homologous recombination and non-homologous end-joining pathways of DNA double-strand break repair have overlapping roles in the maintenance of chromosomal integrity in vertebrate cells. EMBO J 1998; 17: 5497-5508; Haber, J. E. Partners and ys repairing a double-strand break.
Trends Genet 2000; 16: 259-264). NHEJ repairs the ty of DSBs. In NHEJ, DSBs are recognized by the Ku n that binds and then activates the tic subunit of DNA-PK.
This leads to recruitment and activation of end-processing enzymes, polymerases and DNA ligase IV (Collis, S. J., DeWeese, T. L., Jeggo P. A., Parker, A.R. The life and death of DNAPK.
Oncogene 2005; 24: 949-961). NHEJ is primarily lled by DNA-PK and thus inhibition of DNA-PK is an attractive approach to modulating the repair response to exogenously induced DSBs. Cells deficient in components of the NHEJ pathway are defective in DSB repair and highly sensitive to ionizing radiation and topoisomerase poisons (reviewed by Smith, G. C. M., Jackson, S.P. The DNA-dependent n kinase. Genes Dev 1999; 13: 916-934; Jeggo, P.A., Caldecott, K., Pidsley, S., Banks, G.R. Sensitivity of Chinese hamster ovary mutants defective in DNA double strand break repair to topoisomerase II inhibitors.
Cancer Res 1989; 49: 7057-7063). A DNA-PK tor has been reported to have the same effect of sensitizing cancer cells to therapeutically induced DSBs (Smith, G. C. M., Jackson, S.P. The DNA-dependent protein kinase. Genes Dev 1999; 13: 916-934).

The term “second active agent(s)” means a receptor tyrosine kinase (RTK) inhibitor (for example, an EGFR inhibitor), a phosphoinositide se (PI3K) pathway inhibitor, a serine/threonine-protein kinase (RAF) and mitogen-activated protein kinase/extracellular signal-regulated protein kinase kinase (MEK) y inhibitor, a DNA damaging agent (for example, a PARP tor), a DNA damage response agent, a cytoskeleton perturbagen, a protein stability inhibitor, or a Bruton’s ne kinase (BTK) tor, including those described herein in Section 4.4.
The term “cancer” includes, but is not limited to, blood borne tumors and solid . Blood borne tumors include lymphomas, ias and myelomas. Lymphomas and leukemias are malignancies arising among white blood cells. The term “cancer” also refers to any of various malignant neoplasms characterized by the proliferation of cells that can invade surrounding tissue and metastasize to new body sites. Both benign and malignant tumors are classified according to the type of tissue in which they are found. For example, fibromas are neoplasms of fibrous connective tissue, and melanomas are abnormal growths of pigment (melanin) cells. Malignant tumors originating from epithelial tissue, e.g., in skin, bronchi, and stomach, are termed carcinomas. Malignancies of epithelial glandular tissue such as are found in the breast, prostate, and colon, are known as adenocarcinomas. Malignant growths of connective tissue, e.g., muscle, cartilage, lymph tissue, and bone, are called sarcomas. 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. Bone tissues are one of the most favored sites of metastases of malignant tumors, occurring in about 30% of all cancer cases. Among malignant tumors, cancers of the lung, breast, prostate or the like are particularly known to be likely to metastasize to bone.
In the context of neoplasm, , tumor growth or tumor cell growth, inhibition may be assessed by delayed appearance of primary or secondary tumors, slowed development of primary or secondary tumors, decreased occurrence of primary or secondary tumors, slowed or decreased severity of secondary effects of disease, arrested tumor growth and regression of tumors, among . In the e, complete inhibition, is ed to herein as prevention or chemoprevention. In this context, the term “prevention” includes either preventing the onset of clinically evident neoplasia ther or preventing the onset of a preclinically evident stage of sia in individuals at risk. Also intended to be encompassed by this definition is the tion of transformation into malignant cells or to arrest or reverse the progression of premalignant cells to malignant cells. This includes lactic treatment of those at risk of developing the neoplasia.
The term “refractory B-cell non-Hodgkin’s lymphoma” as used herein is defined as B-cell non-Hodgkin’s ma which was d with an anti-CD-20 antibody-containing regimen, for example rituximab-containing regimen, (i) without achieving at least a partial response to therapy or (ii) which progressed within 6 months of treatment.
The term sed B-cell non-Hodgkin’s ma” as used herein is defined as B-cell non-Hodgkin’s lymphoma which progressed after ≥ 6 months post-treatment with an anti- CD-20 antibody-containing regimen, for example rituximab-containing regimen, after achieving partial response or complete response to therapy.
A person of ordinary skill will appreciate that diseases characterized as “B-cell lymphoma” exist as a continuum of diseases or disorders. While the continuum of B-cell lymphomas is mes discussed in terms of “aggressive” B-cell lymphomas or “indolent” B-cell lymphomas, a person of ordinary skill will appreciate that a B-cell lymphoma characterized as indolent may ss and become an sive B-cell lymphoma. sely, an aggressive form of B-cell ma may be downgraded to an indolent or stable form of B-cell lymphoma. Reference is made to indolent and aggressive B-cell lymphomas as generally understood by a person d in the art with the recognition that such characterizations are inherently dynamic and depend on the particular circumstances of the individual.
As used , and unless otherwise specified, the term “in combination with” includes the administration of two or more therapeutic agents simultaneously, concurrently, or tially within no specific time limits unless otherwise indicated. In one embodiment, a TOR kinase inhibitor is administered in combination with a second active agent. In one embodiment, the agents are present in the cell or in the subject’s body at the same time or exert their biological or therapeutic effect at the same time. In one embodiment, the therapeutic agents are in the same ition or unit dosage form. In other embodiments, the therapeutic agents are in separate compositions or unit dosage forms. In certain embodiments, a first agent can be administered prior to (e.g., 5 minutes, 15 minutes, 30 minutes, 45 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours, 24 hours, 48 hours, 72 hours, 96 hours, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 8 weeks, or 12 weeks before), essentially concomitantly with, or subsequent to (e.g., 5 minutes, 15 minutes, 30 minutes, 45 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours, 24 hours, 48 hours, 72 hours, 96 hours, 1 week, 2 weeks, 3 weeks, 4 weeks, weeks, 6 weeks, 8 weeks, or 12 weeks after) the administration of a second therapeutic agent, or any combination thereof. For example, in one embodiment, the first agent can be administered prior to the second therapeutic agent, for e.g. 1 week. In another, the first agent can be stered prior to (for example 1 day prior) and then concomitant with the second therapeutic agent.
The terms “patient” and “subject” as used herein include an animal, including, but not limited to, an animal such as a cow, monkey, horse, sheep, pig, chicken, turkey, quail, cat, dog, mouse, rat, rabbit or guinea pig, in one embodiment a mammal, in another embodiment a human. In one embodiment, a “patient” or “subject” is a human having a cancer.
In the context of a cancer, inhibition may be assessed by inhibition of disease progression, inhibition of tumor growth, reduction of primary tumor, relief of tumor-related symptoms, inhibition of tumor ed factors (including tumor secreted hormones, such as those that bute to carcinoid syndrome), d appearance of primary or secondary tumors, slowed development of primary or secondary tumors, decreased occurrence of primary or secondary tumors, slowed or decreased severity of secondary s of disease, arrested tumor growth and regression of tumors, increased Time To Progression (TTP), increased Progression Free Survival (PFS), increased Overall Survival (OS), among others. OS as used herein means the time from ization until death from any cause, and is measured in the intent-to-treat population. TTP as used herein means the time from randomization until objective tumor progression; TTP does not include deaths. As used herein, PFS means the time from randomization until objective tumor progression or death. In one embodiment, PFS rates will be computed using the Kaplan-Meier estimates. In the extreme, complete inhibition, is referred to herein as prevention or chemoprevention. In this context, the term “prevention” includes either preventing the onset of clinically evident cancer altogether or preventing the onset of a preclinically evident stage of a cancer. Also ed to be encompassed by this definition is the prevention of transformation into malignant cells or to arrest or reverse the progression of premalignant cells to malignant cells. This es prophylactic treatment of those at risk of developing a cancer.

In certain embodiments, the treatment of a cancer may be assessed by Response Evaluation Criteria in Solid Tumors (RECIST 1.1) (see Thereasse P., et al. New Guidelines to Evaluate the Response to Treatment in Solid . J. of the National Cancer Institute; 2000; (92) 6 and Eisenhauer E.A., se P., Bogaerts J., et al. New response evaluation criteria in solid tumours: Revised RECIST guideline (version 1.1). European J. Cancer; 2009; (45) 228–247). Overall responses for all le combinations of tumor ses in target and rget lesions with our without the appearance of new lesions are as follows: Target lesions Non-target lesions New lesions Overall response CR CR No CR CR Incomplete No PR response/SD PR Non-PD No PR SD Non-PD No SD PD Any Yes or no PD Any PD Yes or no PD Any Any Yes PD CR = complete response; PR = partial response; SD = stable disease; and PD = ssive disease.
With respect to the evaluation of target lesions, complete response (CR) is the disappearance of all target lesions, partial response (PR) is at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum longest er, progressive disease (PD) is at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since the treatment started or the appearance of one or more new lesions and stable disease (SD) is neither sufficient age to qualify for partial response nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum longest diameter since the treatment started.
With respect to the evaluation of non-target lesions, complete se (CR) is the earance of all non-target lesions and ization of tumor marker level; incomplete response/stable disease (SD) is the persistence of one or more non-target lesion(s) and/or the maintenance of tumor marker level above the normal limits, and progressive disease (PD) is the appearance of one or more new lesions and/or unequivocal progression of existing non-target lesions.
] The procedures, conventions, and definitions described below provide guidance for enting the recommendations from the Response Assessment for Neuro-Oncology (RANO) Working Group regarding response criteria for rade gliomas (Wen P., Macdonald, DR., Reardon, DA., et al. Updated response assessment criteria for highgrade gliomas: se assessment in neuro-oncology working group. J Clin Oncol 2010; 28: 1963- 1972). Primary modifications to the RANO criteria for Criteria for Time Point Responses (TPR) can include the addition of operational conventions for defining changes in glucocorticoid dose, and the removal of subjects’ al deterioration component to focus on objective radiologic assessments. The baseline MRI scan is defined as the assessment performed at the end of the post-surgery rest period, prior to re-initiating nd treatment. The baseline MRI is used as the reference for ing complete se (CR) and partial response (PR). Whereas, the smallest SPD (sum of the products of perpendicular diameters) obtained either at baseline or at subsequent assessments will be designated the nadir assessment and utilized as the reference for determining progression. For the 5 days ing any protocol-defined MRI scan, subjects receive either no glucocorticoids or are on a stable dose of glucocorticoids. A stable dose is defined as the same daily dose for the 5 consecutive days preceding the MRI scan. If the prescribed glucocorticoid dose is changed in the 5 days before the baseline scan, a new baseline scan is required with glucocorticoid use meeting the criteria described above. The following definitions will be used.
Measurable Lesions: Measurable lesions are contrast-enhancing lesions that can be ed nsionally. A measurement is made of the maximal enhancing tumor diameter (also known as the longest diameter, LD). The greatest perpendicular diameter is ed on the same image. The cross hairs of bidimensional measurements should cross and the t of these diameters will be calculated.
Minimal Diameter: T1-weighted image in which the sections are 5 mm with 1 mm skip. The l LD of a measurable lesion is set as 5 mm by 5 mm. Larger diameters may be required for ion and/or designation as target lesions. After baseline, target lesions that become smaller than the minimum requirement for measurement or become no longer amenable to nsional measurement will be recorded at the default value of 5 mm for each er below 5 mm. Lesions that disappear will be recorded as 0 mm by 0 mm.
Multicentric Lesions: Lesions that are considered multicentric (as opposed to continuous) are lesions where there is normal ening brain tissue between the two (or more) lesions. For multicentric s that are discrete foci of enhancement, the approach is to separately measure each enhancing lesion that meets the inclusion criteria. If there is no normal brain tissue between two (or more) lesions, they will be considered the same lesion.
Nonmeasurable Lesions: All lesions that do not meet the criteria for measurable disease as d above will be considered non-measurable lesions, as well as all nonenhancing and other truly nonmeasurable lesions. Nonmeasurable lesions e foci of enhancement that are less than the specified smallest diameter (i.e., less than 5 mm by 5 mm), nonenhancing lesions (e.g., as seen on ghted post-contrast, T2-weighted, or fluid-attenuated inversion recovery ) images), hemorrhagic or inantly cystic or necrotic lesions, and leptomeningeal tumor. Hemorrhagic lesions often have intrinsic T1-weighted ntensity that could be misinterpreted as enhancing tumor, and for this reason, the pre-contrast T1-weighted image may be examined to exclude ne or al sub-acute hemorrhage.
At baseline, lesions will be classified as follows: Target lesions: Up to measurable lesions can be selected as target lesions with each measuring at least 10 mm by 5 mm, representative of the subject’s disease; rget lesions: All other lesions, including all nonmeasurable lesions (including mass effects and T2/FLAIR findings) and any measurable lesion not selected as a target lesion. At baseline, target lesions are to be measured as described in the definition for measurable lesions and the SPD of all target lesions is to be determined. The presence of all other lesions is to be documented. At all post-treatment evaluations, the baseline classification of lesions as target and non-target lesions will be maintained and lesions will be documented and described in a consistent fashion over time (e.g., recorded in the same order on source documents and eCRFs). All measurable and nonmeasurable lesions must be assessed using the same technique as at baseline (e.g., subjects should be imaged on the same MRI scanner or at least with the same magnet strength) for the duration of the study to reduce ulties in interpreting changes. At each evaluation, target lesions will be measured and the SPD calculated. Non-target lesions will be assessed qualitatively and new lesions, if any, will be documented separately. At each tion, a time point response will be ined for target lesions, non-target s, and new lesion. Tumor progression can be established even if only a subset of lesions is assessed. r, unless progression is observed, objective status (stable disease, PR or CR) can only be determined when all lesions are assessed.
Confirmation assessments for overall time point responses of CR and PR will be performed at the next scheduled assessment, but confirmation may not occur if scans have an interval of < 28 days. Best response, incorporating confirmation requirements, will be derived from the series of time points.
In certain embodiments, ent of a cancer may be assessed by the inhibition of phosphorylation of S6RP, 4E-BP1, AKT and/or DNA-PK in circulating blood and/or tumor cells, and/or skin biopsies or tumor es/aspirates, before, during and/or after treatment with a TOR kinase inhibitor. For example, the inhibition of phosphorylation of S6RP, 4E-BP1, AKT and/or DNA-PK is assessed in B-cells, T-cells and/or monocytes. In other embodiments, treatment of a cancer may be assessed by the inhibition of DNA-dependent protein kinase (DNAPK ) activity in skin samples and/or tumor biopsies/aspirates, such as by assessment of the amount of pDNA-PK S2056 as a biomarker for DNA damage pathways, before, during, and/or after TOR kinase inhibitor treatment. In one embodiment, the skin sample is irradiated by UV light.

In some embodiments, the pharmaceutical compositions described herein are le for oral, parenteral, mucosal, transdermal or topical administration.
The compositions can be administered to a patient orally or parenterally in the conventional form of preparations, such as capsules, microcapsules, tablets, granules, powder, troches, pills, suppositories, injections, suspensions and syrups. Suitable formulations can be prepared by methods commonly employed using conventional, c or inorganic additives, such as an excipient (e.g., sucrose, starch, ol, sorbitol, lactose, glucose, cellulose, talc, calcium phosphate or calcium carbonate), a binder (e.g., cellulose, methylcellulose, hydroxymethylcellulose, polypropylpyrrolidone, polyvinylpyrrolidone, gelatin, gum arabic, polyethyleneglycol, sucrose or starch), a disintegrator (e.g., starch, ymethylcellulose, hydroxypropylstarch, low substituted hydroxypropylcellulose, sodium bicarbonate, calcium phosphate or calcium citrate), a lubricant (e.g., magnesium stearate, light anhydrous silicic acid, talc or sodium lauryl e), a flavoring agent (e.g., citric acid, menthol, glycine or orange powder), a vative (e.g, sodium benzoate, sodium ite, paraben or propylparaben), a izer (e.g., citric acid, sodium citrate or acetic acid), a suspending agent (e.g., methylcellulose, polyvinyl iclone or aluminum stearate), a dispersing agent (e.g., hydroxypropylmethylcellulose), a diluent (e.g., water), and base wax (e.g., cocoa butter, white petrolatum or polyethylene glycol). The effective amount of the TOR kinase inhibitor in the pharmaceutical composition may be at a level that will exercise the desired effect; for example, about 0.005 mg/kg of a patient’s body weight to about 10 mg/kg of a t’s body weight in unit dosage for both oral and parenteral administration.
The dose of a TOR kinase inhibitor and the dose of a second active agent to be administered to a t is rather widely le and can be subject to the judgment of a care practitioner. In general, the TOR kinase inhibitors and a second active agent can be administered one to four times a day in a dose of about 0.005 mg/kg of a patient’s body weight to about 10 mg/kg of a patient’s body weight in a patient, but the above dosage may be properly varied depending on the age, body weight and medical condition of the patient and the type of administration. In one embodiment, the dose is about 0.01 mg/kg of a patient’s body weight to about 5 mg/kg of a patient’s body , about 0.05 mg/kg of a patient’s body weight to about 1 mg/kg of a patient’s body weight, about 0.1 mg/kg of a patient’s body weight to about 0.75 mg/kg of a patient’s body weight or about 0.25 mg/kg of a patient’s body weight to about 0.5 mg/kg of a patient’s body weight. In one embodiment, one dose is given per day. In any given case, the amount of the TOR kinase inhibitor administered will depend on such factors as the solubility of the active component, the formulation used and the route of administration.

In a particular embodiment, provided herein are unit dosage formulations comprising about 7.5 mg, about 8 mg, about 10 mg, about 15 mg, about 30 mg, about 45 mg, about 50 mg, about 75 mg, about 100 mg or about 400 mg of a TOR kinase inhibitor in combination with a second active agent. In a particular embodiment, provided herein are unit dosage ations comprising about 5 mg, about 7.5 mg or about 10 mg of a TOR kinase inhibitor in combination with a second active agent.
In n embodiments, provided herein are unit dosage formulations comprising about 25 mg, about 50 mg, about 75 mg, about 100 mg, about 125 mg, about 150 mg, about 175 mg, about 200 mg, about 225 mg or about 250 mg of a second active agent alone or in combination with a TOR kinase inhibitor.
A TOR kinase inhibitor can be administered in combination with a second active agent once, twice, three, four or more times daily.
A TOR kinase inhibitor can be administered in combination with a second active agent orally for reasons of convenience. In one ment, when administered orally, a TOR kinase inhibitor in combination with a second active agent is stered with a meal and water.
In another ment, the TOR kinase inhibitor in combination with a second active agent is dispersed in water or juice (e.g., apple juice or orange juice) and stered orally as a suspension. In another embodiment, when administered orally, a TOR kinase inhibitor in combination with a second active agent is administered in a fasted state.
The TOR kinase inhibitor can also be stered in combination with a second active agent intravenously, such as intravenous infusion, or subcutaneously, such as subcutaneous injection. The mode of administration is left to the discretion of the health-care practitioner, and can depend t upon the site of the medical condition.
In one ment, provided herein are es containing a TOR kinase inhibitor in combination with a second active agent without an additional carrier, excipient or vehicle.
In another embodiment, provided herein are compositions comprising an effective amount of a TOR kinase inhibitor, an effective amount of a second active agent, and a pharmaceutically acceptable carrier or vehicle, wherein a pharmaceutically acceptable carrier or vehicle can comprise an excipient, diluent, or a e f. In one embodiment, the composition is a pharmaceutical composition.
The compositions can be in the form of tablets, chewable tablets, capsules, solutions, parenteral solutions, s, suppositories and suspensions and the like.
Compositions can be formulated to contain a daily dose, or a convenient fraction of a daily dose, in a dosage unit, which may be a single tablet or capsule or convenient volume of a liquid. In one embodiment, the solutions are prepared from water-soluble salts, such as the hydrochloride salt. In general, all of the compositions are prepared according to known methods in pharmaceutical chemistry. Capsules can be prepared by mixing a TOR kinase inhibitor with a suitable carrier or diluent and filling the proper amount of the e in capsules. The usual carriers and diluents include, but are not limited to, inert powdered substances such as starch of many different kinds, powdered cellulose, especially crystalline and microcrystalline cellulose, sugars such as fructose, ol and sucrose, grain flours and similar edible powders.
] Tablets can be prepared by direct compression, by wet granulation, or by dry granulation. Their formulations usually incorporate diluents, s, lubricants and disintegrators as well as the compound. Typical diluents include, for example, various types of , lactose, mannitol, kaolin, calcium ate or sulfate, inorganic salts such as sodium chloride and powdered sugar. Powdered cellulose derivatives are also useful. In one embodiment, the pharmaceutical ition is lactose-free. Typical tablet binders are substances such as starch, gelatin and sugars such as lactose, fructose, glucose and the like.
Natural and synthetic gums are also convenient, including acacia, alginates, methylcellulose, polyvinylpyrrolidine and the like. Polyethylene glycol, ethylcellulose and waxes can also serve as binders.
A lubricant might be necessary in a tablet formulation to prevent the tablet and punches from sticking in the die. The ant can be chosen from such slippery solids as talc, magnesium and calcium stearate, stearic acid and hydrogenated ble oils. Tablet disintegrators are nces that swell when wetted to break up the tablet and release the compound. They include starches, clays, celluloses, algins and gums. More particularly, corn and potato starches, methylcellulose, agar, bentonite, wood ose, powdered natural sponge, cation-exchange resins, alginic acid, guar gum, citrus pulp and carboxymethyl cellulose, for e, can be used as well as sodium lauryl sulfate. Tablets can be coated with sugar as a flavor and sealant, or with film-forming protecting agents to modify the ution properties of the tablet. The compositions can also be formulated as chewable tablets, for example, by using substances such as ol in the formulation.
] When it is desired to administer a TOR kinase inhibitor in combination with a second active agent as a suppository, typical bases can be used. Cocoa butter is a traditional suppository base, which can be modified by on of waxes to raise its melting point slightly.
Water-miscible suppository bases comprising, particularly, polyethylene glycols of various molecular weights are in wide use.
The effect of the TOR kinase inhibitor in combination with a second active agent can be delayed or prolonged by proper formulation. For example, a slowly soluble pellet of the TOR kinase inhibitor in ation with a second active agent can be prepared and incorporated in a tablet or e, or as a slow-release implantable device. The technique also includes making pellets of several different dissolution rates and filling capsules with a e of the pellets. Tablets or capsules can be coated with a film that resists dissolution for a predictable period of time. Even the parenteral preparations can be made long-acting, by dissolving or ding the TOR kinase inhibitor in combination with a second active agent in oily or emulsified vehicles that allow it to disperse slowly in the serum.
In some embodiments, a pharmaceutically acceptable composition comprising a second active agent comprises from about 5% to about 60% of a second active agent, or a pharmaceutically acceptable salt thereof, based upon total weight of the composition. In some embodiments, a pharmaceutically acceptable composition comprising a second active agent comprises from about 5% to about 15% or about 7% to about 15% or about 7% to about 10% or about 9% to about 12% of a second active agent, based upon total weight of the ition.

Anti-Proliferation Assay. Cells were thawed from a liquid nitrogen preserved state. Once cells expanded and divided at their expected doubling times, screening began. Cells were seeded in growth media in 384-well tissue culture treated plates at cell densities as listed in Table 1.

At the time of treatment, a set of assay plates (which did not e treatment) were ted and ATP levels were measured by adding ATP Lite (Perkin Elmer). These T zero (T0) plates were read using ultra-sensitive luminescence on Envision Plate Readers. Treated assay plates were incubated with compound (single compound or combination) for seventy-two hours. After seventy-two hours, platesweare ped for nt is using e. All data points were collected via automated ses; y controlled; and analyzed. Assay plates were accepted if they passed the following quality control standards: relative luciferase values were consistent throughout the entire experiment, or scoresweare greater than 0.6, untreated/vehicle controls behaved consistently on the plate. The calculation for synergy score is provided below.
Growth Inhibition (GI) was used as a measure of cell ity. The cell viability of vehicle was measured at the time of dosing (T0) and after seventy-two hours (T72). A GI reading of 0% represents no growth inhibition - cells treated with compound and T72 vehicle signals are matched. A GI 100% represents complete growth inhibition - cells treated by compound and T0 vehicle signals are matched. Cell numbers have not increased during the treatment period in wells with GI 100% and may suggest a cytostatic effect for compounds reaching a plateau at this effect level. A GI 200% represents complete death of all cells in the culture well. Compounds reaching an activity plateau of GI 200% are considered cytotoxic. GI is calculated by applying the following test and equation: If T < V0 : 100*[1-(T-V0)/V0] If T ≥ V0 : 100*[1-(T-V0)/(V-V0)] where T is the signal measure for a test article, V is the vehicle-treated control measure, and V0 is the e l e at time zero. This formula is derived from the Growth Inhibition calculation used in the National Cancer Institute’s NCI-60 high throughput screen.
Synergy Score Analysis. Synergy scores were determined using the Chalice Software (Zalicus Inc., Cambridge MA). Briefly, to measure combination effects in excess of Loewe additivity, a scalar measure to characterize the strength of synergistic interaction termed the Synergy Score was used. The Synergy Score is calculated as: Synergy Score = log fX log FY∑max(0,Idata)(Idata – ILoewe) wherein Idata is the observed inhibition at a given combination of drug concentrations.
The calculation for vity is: ILoewe that satisfies (X/XI) + (Y/YI) = 1, where XI and YI are the single agent ive concentrations for the observed combination effect I.
Activity observed in excess of Loewe additivity identifies potential synergistic interaction.
The fractional inhibition for each component agent and combination point in the matrix was calculated relative to the median of all e-treated l wells. The Synergy Score equation integrates the experimentally -observed ty volume at each point in the matrix in excess of a model surface numerically derived from the activity of the component agents using the Loewe model for additivity. Additional terms in the Synergy Score equation (above) were used to normalize for s dilution factors used for individual agents and to allow for comparison of synergy scores across an entire experiment. The inclusion of positive inhibition gating or an Idata multiplier removes noise near the zero effect level, and biases results for synergistic interactions at that occur at high ty levels.
Self-Cross-Based Combination Screen is. Combinations where the synergy score is greater than the mean self-cross plus two standard deviations (2σ’s) can be considered ate synergies at the 95% ence level.
In order to ively establish hit criteria for the combination screen analysis, twenty compounds were selected to be self-crossed across the seventeen cell line panel as a means to empirically determine a baseline additive, non-synergistic response. The identity of the twenty self-cross compounds was determined by selecting compounds with a variety of maximum response values and single agent dose response steepness. Those drug ations which yielded effect levels that statistically superseded those baseline vity values were considered synergistic.
Compound 1 had varying activity across the een cell line panel. For each cell line, a three-fold, ten-point dose titration was performed in 384-well plate format. For cell lines where the GI50 reached inhibition levels of greater than fifty percent, the median GI50 was 0.14 µM. Synergy scores for treatment of breast cancer cell line panel with nd 1 and second active agents are provided in Table 2a and Table 2b. Synergy scores that exceed the mean self-cross thresholds plus two standard deviations (2σ) are depicted in bold.
Conclusion: As can be seen in Table 2a and Table 2b, Compound 1 in combination with certain second active agents showed synergistic effects in multiple breast cancer cell lines .

Cell viability assay for NSCLC and Ovarian cell lines. Cell viability was assessed using the Cell Titer-Glo® Luminescent Cell Viability Assay, Catalog Number G7570 ga Corporation, Madison, WI). The assay is a homogenous method of determining the number of viable cells in culture based on quantitation of the ine triphosphate (ATP) t, an indicator of metabolically active cells. The homogenous assay procedure involves adding the single reagent (CellTiter-Glo Reagent) ly to cells cultured in serumsupplemented medium. Cells were plated into a 96-well flat bottom plate (Costar Catalog Number 33595) at densities that were previously optimized for each cell line. The cells were incubated overnight in 5% CO2 at 37 ºC. The following day, compound dilutions were prepared and all concentrations were assayed in triplicate. The cells were incubated with TOR kinase inhibitor, or TOR kinase inhibitor and second active agent, in 5% CO2 at 37 ºC for 3 days. After a 3-day incubation period, 100 μL of CellTiter-Glo reagent was added to each well for 2 min with shaking and further incubated for 10 min (no shaking) at room temperature to stabilize the signal. The luminescence was measured on the VICTOR X2 abel plate reader. The percent growth inhibition was calculated using the DMSO control in the same plate (no nd) se as 100% cell growth. For single compound treatments (TOR kinse inhibitor and second active agents separately), the e values from triplicates were plotted to obtain IC50 values using software XLfit from IDBS. The a used for determining IC50 in XLfit was model number 205, which utilizes a 4 Parameter Logistic Model or Sigmoidal Dose- Response Model to calculate the IC50 values. Results are set forth in Table 4, Table 5, Table 6 and Table 7.
Measurement of synergism of cell proliferation inhibition using TOR kinase inhibitor in combination with second active agent. The cell viability assay was first performed with the TOR kinase inhibitor and the individual second active agents, to determine the dose range for subsequent combination studies. To maintain r potency for the TOR kinase inhibitor and the second active agent, the highest combination dose started at the approximate IC50 for each compound, with a nt ratio of 1:1 or 1:10 during dilutions. The TOR kinase inhibitor and the second active agent were each added to one well containing a final concentration of 0.2% DMSO (in triplicate). In the same plate in triplicate, the cells were treated with the TOR kinase tor and each second active agent either simultaneously or sequentially (containing 0.2% DMSO). The number of cells affected by compound treatment was normalized to the DMSO control (100% viability) and the data was imported into the CalcuSyn software (V2.1, Biosoft). ism was quantitated by the combination index (CI) using CalcuSyn according to Chou-Talalay’s CI method with mathematical modeling and simulations. The CI value indicates strong synergism if the value is between 3, ism between 0.3-0.7, moderate synergism 0.7-0.85, slight synergism 0.85-0.90 and nearly additive 0.90-1.10 (Trends Pharmacol. Sci. 4, 450-454, 1983). ED50 is the median effect dose at which a 50% growth tion is achieved. Results are set forth in Table 4, Table 5, Table 6 and Table 7.

The TOR kinase inhibitor and second agent were added to an empty 384-well flat, clear bottom, black polystyrene, TC-Treated plate (Cat#3712, Corning, MA) via an acoustic dispenser (EDC Biosystems). The TOR kinase inhibitor was serially diluted 3-fold across the plate for nine concentrations and the second agent was serially diluted 3-fold down the plate for seven concentrations. An orthogonal titration of the two agents was performed to create 63 different ations of the compounds. Both compounds were also added alone to ine their affects as single agents. DMSO (no nd) was used as control for 100% viability and background (no cells). Final assay DMSO concentration was 0.2% (v/v). Cells were added directly on top of the compounds at an optimized density to ensure that the cell growth was within the linear detection range of the assay after four days in culture. At its endpoint, cell viability was determined using Promega’s CellTiter-Glo Luminescent Cell Viability Assay (Cat#G7573, Promega, WI) using the manufacturer’s standard operating procedures.
Background subtracted luminescence counts were converted to percentages of cell ity with respect to DMSO treated control cells. Dose response curves were generated using XLFit4 (IDBS, UK) by fitting the percentage of control data at each concentration using a 4 Parameter Logistic Model/Sigmoidal Dose-Response Model [y = (A+((B-A)/(1+((C/x)^D))))]. To evaluate the combinatorial effect of the two agents on a cell line, data was analyzed by comparing its combinatorial response against the tical additive response of the two agents alone. The expected ve effect of two agents (A and B) was calculated using the fractional product method (Webb 1961): (fu)A,B = (fu)A x (fu)B where fu=fraction unaffected by treatment.
Synergism of a combination is determined when the observed fraction unaffected in combination is less than (fu)A,B, while an additive effect is determined when the observed fraction cted in combination = (fu)A,B. Results are set forth in Table 8, Table 9 and Table 10.
