  • Another aspect of the present invention relates to the use of such combinations as described herein for the preparation of a medicament for the treatment or prophylaxis of a disease, particularly for the treatment of cancer.
  • Another aspect of the present invention relates to such combinations as described herein for use in the treatment or prophylaxis of a disease, particularly for use in the treatment of cancer.
  • Another aspect of the present invention relates to the use of a ATR inhibitor as a sensitizer of cells to Bub1 inhibitors or vice versa.
  • Yet another aspect of the present invention relates to methods of treatment or prophylaxis of a cancer in a subject, comprising administering to said subject a therapeutically effective amount of a combination as described herein.
  • kits comprising a combination of:
  • component B as defined supra, or a pharmaceutically acceptable salt, solvate, hydrate or stereoisomer thereof ;
  • components A and B are in the form of a pharmaceutical formulation which is ready for use to be administered simultaneously, concurrently, separately or sequentially.
  • Cell cycle deregulation represents one of the classical hallmarks of cancer [Hanahan D and Weinberg RA, Cell 100, 57, 2000; Hanahan D and Weinberg RA, Cell 144, 646, 201 1 ] and consequently cell cycle arrest is the predominant mode of action of a lot of the cancer drugs on the market including " anti-mitotics ' such as taxanes and vinca alkaloids.
  • the concept of cell cycle checkpoint regulation offers a novel approach to cancer treatment: inactivation of cell cycle checkpoints is considered to drive tumor cells into cell divison despite DNA damage or unattached/misattached chromosomes resulting in a lethal degree of DNA damage or aneuploidy.
  • the spindle assembly checkpoint controls the accurate attachment of microtubules of the spindle device to the kinetochors (the attachment site for microtubules) of the duplicated chromosomes.
  • the SAC is active as long as unattached kinetochores are present and generates a wait-signal to give the dividing cell the time to ensure that each kinetochore is attached to a spindle pole, and to correct attachment errors [for recent review see Musacchio A, Curr. Biol. 25, R1002-R1018, 2015].
  • the SAC signal is initiated by multipolar-spindle 1 (Mpsl )-mediated phosphorylation of Met-Glu-Leu-Thr (MELT) motifs on the kinetochore scaffold 1 (KNL-1 ) protein to generate docking sites for budding uninhibited by benzimidazole 1 (Bub1 )/Bub3 dimers.
  • Mpsl multipolar-spindle 1
  • MELT Met-Glu-Leu-Thr
  • Bub1 kinetochore scaffold 1
  • Bub3 dimers The N-terminal non-catalytic part of Bub1 represents a scaffold for the assembly of mitotic arrest deficient 1 (MAD1 )/MAD2, BubR1 and centromere protein E (CENP-E) proteins.
  • MCC diffusible mitotic checkpoint complex
  • APC/C ubiquitin ligase anaphase-promoting complex/cyclosome
  • Bub1 kinase phosphorylates histone H2A at Thr120 within the centromeric region of the duplicated chromosomes thereby creating binding sites for shugoshin proteins (Sgo) 1 and 2, which protect centromeric cohesin from premature degradation, and for the chromosomal passenger complex consisting of INCENP, survivin, borealin and Aurora B (AurB) [Kawashima et al. Science 327, 172, 2010; Watanabe Y, Cold Spring Harb. Symp. Quant. Biol. 75, 419, 2010]. Specific inhibition of Bub1 kinase activity results in reduced levels of Sgo1 and Sgo2 at mitotic centromeres.
  • AurB fails to concentrate at the centromeres and was instead found to be spread over the chromosome arms [Baron et al. eLife 5, e12187, 2016].
  • AurB activity localized at the centromeric region is essential for the resolution of microtubule - kinetochore attachment errors such as syntelic and merotelic attachments.
  • Dyslocatization of AurB due to Bub1 kinase inactivation strongly compromizes the cells ability to resolve attachment errors and results in an increased rate of chromosome aligment defects [Ricke et al. J. Cell Biol. 199, 931 , 2012], in particular in presence of attachment error inducing agents such as microtubule stabilizers paclitaxel or docetaxel.
  • Bub1 kinase was reported to be involved in the DNA damage signaling pathway downstream of ATM kinase [Yang et al. DNA Repair 1 1 , 185, 2012] and in nonhomologous end-joining system of DNA double strand break repair [Jessulat et al. Mol. Cell. Biol. 35, 2448, 2015].

BACKGROUND
Cell cycle deregulation represents one of the classical hallmarks of cancer [Hanahan D and Weinberg RA, Cell 100, 57, 2000; Hanahan D and Weinberg RA, Cell 144, 646, 201 1 ] and consequently cell cycle arrest is the predominant mode of action of a lot of the cancer drugs on the market including "anti-mitotics' such as taxanes and vinca alkaloids. The concept of cell cycle checkpoint regulation offers a novel approach to cancer treatment: inactivation of cell cycle checkpoints is considered to drive tumor cells into cell divison despite DNA damage or unattached/misattached chromosomes resulting in a lethal degree of DNA damage or aneuploidy.
The spindle assembly checkpoint (SAC, also known as spindle checkpoint or mitotic checkpoint) controls the accurate attachment of microtubules of the spindle device to the kinetochors (the attachment site for microtubules) of the duplicated chromosomes. The SAC is active as long as unattached kinetochores are present and generates a wait-signal to give the dividing cell the time to ensure that each kinetochore is attached to a spindle pole, and to correct attachment errors [for recent review see Musacchio A, Curr. Biol. 25, R1002-R1018, 2015].
The SAC signal is initiated by multipolar-spindle 1 (Mpsl )-mediated phosphorylation of Met-Glu-Leu-Thr (MELT) motifs on the kinetochore scaffold 1 (KNL-1 ) protein to generate docking sites for budding uninhibited by benzimidazole 1 (Bub1 )/Bub3 dimers. The N-terminal non-catalytic part of Bub1 represents a scaffold for the assembly of mitotic arrest deficient 1 (MAD1 )/MAD2, BubR1 and centromere protein E (CENP-E) proteins. The inactive open from of MAD2 (o-MAD2) gets converted to the active closed conformation (c-MAD2) which binds cell-division cycle 20 homolog (CDC20) and BubR1 to form the diffusible mitotic checkpoint complex (MCC) which inhibits the ubiquitin ligase anaphase-promoting complex/cyclosome (APC/C) and subsequently leads to mitotic arrest. Note that MCC generation requires Bub1 protein, however, its kinase function is not involved.
Bub1 kinase phosphorylates histone H2A at Thr120 within the centromeric region of the duplicated chromosomes thereby creating binding sites for shugoshin proteins (Sgo) 1 and 2, which protect centromeric cohesin from premature degradation, and for the chromosomal passenger complex consisting of INCENP, survivin, borealin and Aurora B (AurB) [Kawashima et al. Science 327, 172, 2010; Watanabe Y, Cold Spring Harb. Symp. Quant. Biol. 75, 419, 2010]. Specific inhibition of Bub1 kinase activity results in reduced levels of Sgo1 and Sgo2 at mitotic centromeres. Furthermore, AurB fails to concentrate at the centromeres and was instead found to be spread over the chromosome arms [Baron et al. eLife 5, e12187, 2016]. AurB activity localized at the centromeric region is essential for the resolution of microtubule - kinetochore attachment errors such as syntelic and merotelic attachments. Dyslocatization of AurB due to Bub1 kinase inactivation strongly compromizes the cells ability to resolve attachment errors and results in an increased rate of chromosome aligment defects [Ricke et al. J. Cell Biol. 199, 931 , 2012], in particular in presence of attachment error inducing agents such as microtubule stabilizers paclitaxel or docetaxel.
The recognition and repair of DNA damage is essential for normal cellular function and maintenance of genome stability. The related kinases ATR (Ataxia-telangiectasia and Rad3 related) and ATM (Ataxia-telangiectasia Mutated) get readily activated as soon as a cell senses DNA damage [recently reviewed in Weber & Ryan, Pharmacol. Ther. 149, 124, 2015]. Although ATM is preferentially activated by DNA double strand breaks and ATR by single-stranded DNA, they are able to compensate for each other. However, recently it has been shown that in a genetic background of ATM inactivation, inhibition of ATR results in a synthetic lethal phenotype [Reaper et al. Nat. Chem. Biol. 7, 428, 201 1].
Bub1 kinase was reported to be involved in the DNA damage signaling pathway downstream of ATM kinase [Yang et al. DNA Repair 1 1 , 185, 2012] and in nonhomologous end-joining system of DNA double strand break repair [Jessulat et al. Mol. Cell. Biol. 35, 2448, 2015].
However, the state of the art neither discloses the combinations of the present invention comprising an inhibitor of Bub1 kinase and an inhibitor of ATR kinase nor the use of an ATR inhibitor as a sensitizer of cells to Bub1 inhibitors or vice versa.
SUMMARY of the INVENTION
Surprisingly, it was observed that combinations of Bub1 kinase inhibitor or pharmaceutically acceptable salts, solvates, hydrates or stereoisomers thereof, with ATR kinase inhibitors or pharmaceutically acceptable salts, solvates, hydrates or stereoisomers thereof, showed additive or more that additive (synergistic) antiproliferative activity, particularly in ATM signaling proficient human tumor cell lines.
Therefore, in accordance with a first aspect, the present invention provides combinations of at least two components, component A and component B, component A being an inhibitor of Bub1 -kinase or a pharmaceutically acceptable salt, solvate, hydrate or stereoisomer thereof, and component B being an ATR inhibitor or a pharmaceutically acceptable salt, solvate, hydrate or stereoisomer thereof. In a further embodiment of the a first aspect, the present invention provides combinations of at least two components, component A and component B, component A being an inhibitor of Bub1 kinase or an N-oxide, a salt, a tautomer, a solvate, a hydrate or a stereoisomer thereof, or a salt of said N-oxide, tautomer, solvate, hydrate or stereoisomer, or a mixture of same, and component B being an ATR kinase inhibitor or a stereoisomer, a tautomer, an N-oxide, a hydrate, a solvate or a pharmaceutically acceptable salt thereof, or a mixture of same.

The term "substituted" means that one or more hydrogens on the designated atom is replaced with a selection from the indicated group, provided that the designated atom's normal valency under the existing circumstances is not exceeded, and that the substitution results in a stable compound. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.
The term "optionally substituted" means optional substitution with the specified groups, radicals or moieties. Ring system substituent means a substituent attached to an aromatic or nonaromatic ring system which, for example, replaces an available hydrogen on the ring system. By "stable compound' or "stable structure" is meant a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent.
As used herein, the term "one or more", e.g. in the definition of the substituents of the compounds of the general formulae of the present invention, is understood as meaning "one, two, three, four or five, particularly one, two, three or four, more particularly one, two or three, even more particularly one or two".
The invention also includes all suitable isotopic variations of a compound (i.e. component A, B or C(when present)) used in the combination of the present invention. An isotopic variation of a compound is defined as one in which at least one atom is replaced by an atom having the same atomic number but an atomic mass different from the atomic mass usually or predominantly found in nature. Examples of isotopes that can be incorporated into a compound used in the combination of the present invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulphur, fluorine, chlorine, bromine and iodine, such as 2H (deuterium), 3H (tritium), 11C, 13C, 14C, 15N, 170, 180, 32P, 33P, 33S, 34S, 35S, 36S, 18F, 36CI, 82Br, 123l, 124l, 129l and 1311, respectively. Certain isotopic variations of a compound used in the combination of the present invention, for example, those in which one or more radioactive isotopes such as 3H or 14C are incorporated, are useful in drug and/or substrate tissue distribution studies. Tritiated and carbon-14, i.e., 14C, isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with isotopes such as deuterium may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements and hence is preferred in some circumstances. Isotopic variations of a compound of the invention can generally be prepared by conventional procedures known by a person skilled in the art such as by the illustrative methods or by the preparations described in the examples hereafter using appropriate isotopic variations of suitable reagents.
Where the plural form of the word compounds, salts, polymorphs, hydrates, solvates and the like, is used herein, this is taken to mean also a single compound, salt, polymorph, isomer, hydrate, solvate or the like. The compounds used in the combination of this invention optionally contain one or more asymmetric centre, depending upon the location and nature of the various substituents desired. Asymmetric carbon atoms is present in the (R) or (S) configuration, resulting in racemic mixtures in the case of a single asymmetric centre, and diastereomeric mixtures in the case of multiple asymmetric centres. In certain instances, asymmetry may also be present due to restricted rotation about a given bond, for example, the central bond adjoining two substituted aromatic rings of the specified compounds.
The compounds used in the combination of the present invention optionally contain sulphur atoms which are asymmetric, such as an asymmetric sulfoxide, of structure:
II
0 , for example, in which * indicates atoms to which the rest of the molecule can be bound.
Substituents on a ring may also be present in either cis or trans form. It is intended that all such configurations (including enantiomers and diastereomers), are included within the scope of the present invention.
Preferred compounds used in the combination are those which produce the more desirable biological activity. Separated, pure or partially purified isomers and stereoisomers or racemic or diastereomeric mixtures of the compounds used in the combination of this invention are also included within the scope of the present invention. The purification and the separation of such materials can be accomplished by standard techniques known in the art.
The optical isomers can be obtained by resolution of the racemic mixtures according to conventional processes, for example, by the formation of diastereoisomeric salts using an optically active acid or base or formation of covalent diastereomers. Examples of appropriate acids are tartaric, diacetyltartaric, ditoluoyltartaric and camphorsulfonic acid. Mixtures of diastereoisomers can be separated into their individual diastereomers on the basis of their physical and/or chemical differences by methods known in the art, for example, by chromatography or fractional crystallisation. The optically active bases or acids are then liberated from the separated diastereomeric salts. A different process for separation of optical isomers involves the use of chiral chromatography (e.g., chiral HPLC columns), with or without conventional derivatisation, optimally chosen to maximise the separation of the enantiomers. Suitable chiral HPLC columns are manufactured by Daicel, e.g., Chiracel OD and Chiracel OJ among many others, all routinely selectable. Enzymatic separations, with or without derivatisation, are also useful. The optically active compounds of this invention can likewise be obtained by chiral syntheses utilizing optically active starting materials.
In order to limit different types of isomers from each other reference is made to lUPAC Rules Section E (Pure Appl Chem 45, 1 1 -30, 1976).
The present invention includes all possible stereoisomers of the compounds used in the combination of the present invention as single stereoisomers, or as any mixture of said stereoisomers, e.g. R- or S- isomers, or E- or Z-isomers, in any ratio. Isolation of a single stereoisomer, e.g. a single enantiomer or a single diastereomer, of a compound used in the combination of the present invention is achieved by any suitable state of the art method, such as chromatography, especially chiral chromatography, for example.
Further, the compounds used in the combination of the present invention may exist as tautomers.
For example, any compound used in the present combination which contains a pyrazole moiety as a heteroaryl group for example can exist as a 1 H tautomer, or a 2H tautomer, or even a mixture in any amount of the two tautomers, or a triazole moiety for example can exist as a 1 H tautomer, a 2H tautomer, or a 4H tautomer, or even a mixture in any amount of said 1 H 2H and 4H tautomers, namely :

2,2-dimethylpropionyloxymethoxy. A selection of in vivo hydrolysable ester forming groups for hydroxy include alkanoyl, benzoyl, phenylacetyl and substituted benzoyl and phenylacetyl, alkoxycarbonyl (to give alkyl carbonate esters), dialkylcarbamoyl and N- (dialkylaminoethyl)-N-alkylcarbamoyl (to give carbamates), dialkylaminoacetyl and carboxyacetyl. The present invention covers all such esters. Furthermore, the present invention includes all possible crystalline forms, or polymorphs, of the compounds used in the combination of the present invention, either as single polymorph, or as a mixture of more than one polymorph, in any ratio. In the context of the properties of the compounds used in the combination of the present invention the term "pharmacokinetic profile" means one single parameter or a combination thereof including permeability, bioavailability, exposure, and pharmacodynamic parameters such as duration, or magnitude of pharmacological effect, as measured in a suitable experiment. Compounds with improved pharmacokinetic profiles can, for example, be used in lower doses to achieve the same effect, may achieve a longer duration of action, or a may achieve a combination of both effects.
In the context of the present invention, the term "treatment" or "treating" includes inhibition, retardation, checking, alleviating, attenuating, restricting, reducing, suppressing, repelling or healing of a disease or the development, the course or the progression of such states and/or the symptoms of such states. The term "disease" includes but is not limited a condition, a disorder, an injury or a health problem. The term "therapy" is understood here to be synonymous with the term "treatment".
The terms "prevention", "prophylaxis" or "preclusion" are used synonymously in the context of the present invention and refer to the avoidance or reduction of the risk of contracting, experiencing, suffering from or having a disease or a development or advancement of such states and/or the symptoms of such states.
The treatment or prevention of a disease may be partial or complete.
The term "combination" in the present invention is used as known to persons skilled in the art and may be present as a fixed combination, a non-fixed combination or kit-of- parts.
A "fixed combination" in the present invention is used as known to persons skilled in the art and is defined as a combination wherein component A and component B are present together in one unit dosage or in a single entity. One example of a "fixed combination" is a pharmaceutical composition wherein the said component A and the said component B are present in admixture for simultaneous administration, such as in a formulation. Another example of a "fixed combination" is a pharmaceutical combination wherein the said component A and the said component B are present in one unit without being in admixture.
A non-fixed combination or "kit-of-parts" in the present invention is used as known to persons skilled in the art and is defined as a combination wherein the said component A and the said component B (and optionally component C) are present in more than one unit. One example of a non-fixed combination or kit-of-parts is a combination wherein the said component A and the said component B (and optionally component C) are present separately, for example in different and separate pharmaceutical compositions. The components of the non-fixed combination or kit-of-parts may be administered separately, sequentially, simultaneously, concurrently or chronologically staggered. Any such combination is covered by the present invention.

Illustrative of oils which can be used in the parenteral formulations of this invention are those of petroleum, animal, vegetable, or synthetic origin, for example, peanut oil, soybean oil, sesame oil, cottonseed oil, corn oil, olive oil, petrolatum and mineral oil. Suitable fatty acids include oleic acid, stearic acid, isostearic acid and myristic acid. Suitable fatty acid esters are, for example, ethyl oleate and isopropyl myristate. Suitable soaps include fatty acid alkali metal, ammonium, and triethanolamine salts and suitable detergents include cationic detergents, for example dimethyl dialkyl ammonium halides, alkyl pyridinium halides, and alkylamine acetates; anionic detergents, for example, alkyl, aryl, and olefin sulfonates, alkyl, olefin, ether, and monoglyceride sulfates, and sulfosuccinates; non-ionic detergents, for example, fatty amine oxides, fatty acid alkanolamides, and poly(oxyethylene-oxypropylene)s or ethylene oxide or propylene oxide copolymers; and amphoteric detergents, for example, alkyl-beta- aminopropionates, and 2-alkylimidazoline quarternary ammonium salts, as well as mixtures. The parenteral compositions of this invention will typically contain from about 0.5% to about 25% by weight of the active ingredient in solution. Preservatives and buffers may also be used advantageously. In order to minimize or eliminate irritation at the site of injection, such compositions may contain a non-ionic surfactant having a hydrophile- lipophile balance (HLB) preferably of from about 12 to about 17. The quantity of surfactant in such formulation preferably ranges from about 5% to about 15% by weight. The surfactant can be a single component having the above HLB or can be a mixture of two or more components having the desired HLB.
Illustrative of surfactants used in parenteral formulations are the class of polyethylene sorbitan fatty acid esters, for example, sorbitan monooleate and the high molecular weight adducts of ethylene oxide with a hydrophobic base, formed by the condensation of propylene oxide with propylene glycol.
The pharmaceutical compositions can be in the form of sterile injectable aqueous suspensions. Such suspensions may be formulated according to known methods using suitable dispersing or wetting agents and suspending agents such as, for example, sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethyl-cellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents which may be a naturally occurring phosphatide such as lecithin, a condensation product of an alkylene oxide with a fatty acid, for example, polyoxyethylene stearate, a condensation product of ethylene oxide with a long chain aliphatic alcohol, for example, heptadeca-ethyleneoxycetanol, a condensation product of ethylene oxide with a partial ester derived form a fatty acid and a hexitol such as polyoxyethylene sorbitol monooleate, or a condensation product of an ethylene oxide with a partial ester derived from a fatty acid and a hexitol anhydride, for example polyoxyethylene sorbitan monooleate.
The sterile injectable preparation can also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent. Diluents and solvents that may be employed are, for example, water, Ringer's solution, isotonic sodium chloride solutions and isotonic glucose solutions. In addition, sterile fixed oils are conventionally employed as solvents or suspending media. For this purpose, any bland, fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid can be used in the preparation of injectables. Components of the invention can also be administered in the form of suppositories for rectal administration of the drug. These components can be prepared by mixing the drug with a suitable non-irritation excipient which is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials are, for example, cocoa butter and polyethylene glycol.
Another formulation employed in the methods of the present invention employs transdermal delivery devices ("patches"). Such transdermal patches may be used to provide continuous or discontinuous infusion of the compounds of the present invention in controlled amounts. The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art (see, e.g., US Patent No. 5,023,252, issued June 1 1 , 1991 , incorporated herein by reference). Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents.
Controlled release formulations for parenteral administration include liposomal, polymeric microsphere and polymeric gel formulations that are known in the art.
It can be desirable or necessary to introduce a component of the present invention to the patient via a mechanical delivery device. The construction and use of mechanical delivery devices for the delivery of pharmaceutical agents is well known in the art. Direct techniques for, for example, administering a drug directly to the brain usually involve placement of a drug delivery catheter into the patient's ventricular system to bypass the blood-brain barrier. One such implantable delivery system, used for the transport of agents to specific anatomical regions of the body, is described in US Patent No. 5,01 1 ,472, issued April 30, 1991.

The term "ATM proficient" (or "ATM signaling proficient") tumor as used herein means a tumor or tumor cell that expresses biologically functional ATM protein. The term "biologically functional ATM protein" includes wildtype ATM protein and mutant ATM protein, which possesses a silent or a functional mutation.
The term "silent mutation" of the ATM gene means a mutation which does not change the function of the ATM gene, its corresponding RNA or its corresponding ATM protein compared to the function of the respective wildtype ATM gene, corresponding wildtype RNA or corresponding wildtype ATM protein.
The term "functional mutation" of the ATM gene means a mutation which results in an altered function of the ATM gene, its corresponding RNA or its corresponding ATM protein compared to the function of the respective wildtype ATM gene, corresponding wildtype RNA or corresponding wildtype ATM protein.
The term "altered function" as used herein means either reduced or increased function of the ATM gene, its corresponding RNA or its corresponding ATM protein compared to the function of the respective wildtype ATM gene, corresponding wildtype RNA or corresponding wildtype ATM protein. The term "altered function" does not include the complete loss of the function of the ATM gene, its corresponding RNA or its corresponding ATM protein compared to the function of the respective wildtype ATM gene, corresponding wildtype RNA or corresponding wildtype ATM protein.
For the purpose of the present invention, an altered function which results in the complete loss of the function or the gain of a new function of the ATM gene, its corresponding RNA or its corresponding ATM protein compared to the function of the respective wildtype ATM gene, corresponding wildtype RNA or corresponding wildtype protein, does not produce/result in an "ATM proficient tumor" or "ATM signaling proficient tumor" when no biologically functional ATM protein is expressed/present in the tumor. The functional mutation can be a "deleterious mutation" or an "activating mutation".
The term "deleterious mutation" as used herein means a mutation of the ATM gene which has a deleterious effect on the function of the ATM gene or on the function of its corresponding RNA or its corresponding ATM protein. For example, the deleterious mutation of the ATM gene may result in a reduced gene expression level of said gene, a reduced amount or a reduced activity of the protein corresponding to said gene, provided it does not result in a nonfunctional gene/protein ("loss-of-function") compared to the respective wildtype gene/protein. For the purpose of the present invention, a mutation which results in a complete nonfunctional gene/protein ("loss-of-function") compared to the respective wildtype gene/protein does not result in an "ATM proficient tumor" or "ATM signaling proficient tumor" as no biologically functional ATM protein is expressed/present in the tumor.
The term "activating mutation" as used herein means a mutation of the ATM gene which changes said gene, its corresponding RNA and/or its corresponding ATM protein in such a way, that its effects (e.g. the amount of corresponding RNA protein, or the protein activity) get stronger compared to the respective wildtype gene/RNA protein. The term "activating mutation" does not include a mutation of a gene, in which the protein corresponding to said gene gets a new function compared to the function of the corresponding wildtype protein. For the purpose of the present invention, a mutation which results in a new function compared to the function of the corresponding wildtype ATM gene/protein does not result in an "ATM proficient tumor" or "ATM signaling proficient tumor" as no biologically functional ATM protein is expressed/present therein.
The term "stratification method" as used herein means a method for selection of a patient for treatment with a combination of the present invention by which it is determined whether biologically functional ATM protein is expressed and/or present in the tumor of said patient. When biologically functional ATM protein is expressed and/or present, the patient is selected for treatment with a combination of the present invention, particularly with a therapeutically effective amount of a combination of the present invention.
Preferably, the stratification method is an in-vitro method. An example of a method to determine the presence of biologically functional ATM protein, which can be used in context with the present invention, is described in Nyati et al., "Quantitative and Dynamic Imaging of ATM Kinase Activity", Methods Mol Biol. 2017;1596:131 -145, which is incorporated herein in its entirety by reference.
The term "sample" as used herein means the sample from the subject, preferably an in vitro sample, which is used in the stratification method (as defined herein), e.g. a sample of tumor cells or of tumor tissue, a blood sample, particularly a sample of tumor tissue containing tumor cells.
Preferred uses of the combinations of the invention are for the treatment cancers (and/or metastases thereof) at any stage, with or without pre-treatment, particularly wherein said cancers are ATM signaling proficient.
Preferred uses of the combinations of the invention are for the treatment cancers (and/or metastases thereof) at any stage, with or without pre-treatment, particularly wherein biologically functional ATM protein is present.
Preferred uses of the combinations of the invention are for the treatment cancers (and/or metastases thereof) at any stage, with or without pre-treatment, particularly wherein ATM protein is present and/or expressed.
Preferably the ATM proficient tumor expresses biologically functional ATM protein with at least 1 %, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 1 10%, 120%, 130%, 140% or more (higher) protein activity compared to the corresponding activity of wildtype ATM protein.
Alternatively, the presence of biologically functional ATM protein may be determined according to the methods provided in Human Protein Atlas database version 16.1 (release date 2017.01 .31 . Uhlen et al. A human protein atlas for normal and cancer tissues based on antibody proteomics. Mol Cell Proteomics 2005;4:1920-1932), which classifies the protein expression level of ATM in a tumor biopsy as high, medium, low or not detected. Preferred uses of the combinations of the invention are for the treatment cancers (and/or metastases thereof) at any stage, with or without pre-treatment, wherein biologically functional ATM protein is present as shown by high, medium or low protein expression levels in the Human Protein Atlas database version 16.1 , preferably medium or high protein expression levels of ATM protein are present, more preferably high protein expression levels are present.
Other preferred uses of the combinations of the invention are for the treatment cancers (and/or metastases thereof) at any stage, with or without pre-treatment, which are characterized by high, medium or low ATM protein expression levels according to the Human Protein Atlas database version 16.1 , preferably characterized by medium or high ATM protein expression levels, more preferably characterized by high ATM protein expression levels.
The classification and methods provided in the Human Protein Atlas database version 16.1 may also be used for the stratification/selection of a patient for treatment with combinations of the present invention. Accordingly, in an embodiment when a high, medium or low (preferably high or medium, more preferably high) level of ATM protein is expressed and/or present, the patient is selected for treatment with a combination of the present invention, particularly with a therapeutically effective amount of a combination of the present invention.
One preferred embodiment is the use of the combinations of the invention for the treatment of the disorders tested in the experimental section. The term "inappropriate" within the context of the present invention, in particular in the context of "inappropriate cellular immune responses, or inappropriate cellular inflammatory responses", as used herein, is to be understood as preferably meaning a response which is less than, or greater than normal, and which is associated with, responsible for, or results in, the pathology of said diseases.
Combinations of the present invention might be utilized to inhibit, block, reduce, decrease, etc., cell proliferation and/or cell division, and/or produce apoptosis.

The term "treating" or "treatment" as stated throughout this document is used conventionally, e.g., the management or care of a subject for the purpose of combating, alleviating, reducing, relieving, improving the condition of, eic, of a disease or disorder, such as a carcinoma.
Combinations of the present invention might also be used for treating disorders and diseases associated with excessive and/or abnormal angiogenesis.
Inappropriate and ectopic expression of angiogenesis can be deleterious to an organism. A number of pathological conditions are associated with the growth of extraneous blood vessels. These include, e.g., diabetic retinopathy, ischemic retinal- vein occlusion, and retinopathy of prematurity [Aiello et al. New Engl. J. Med. 1994, 331 , 1480 ; Peer et al. Lab. Invest. 1995, 72, 638], age-related macular degeneration [AMD ; see, Lopez et al. Invest. Opththalmol. Vis. Sci. 1996, 37, 855], neovascular glaucoma, psoriasis, retrolental fibroplasias, angiofibroma, inflammation, rheumatoid arthritis (RA), restenosis, in-stent restenosis, vascular graft restenosis, etc. In addition, the increased blood supply associated with cancerous and neoplastic tissue, encourages growth, leading to rapid tumor enlargement and metastasis. Moreover, the growth of new blood and lymph vessels in a tumor provides an escape route for renegade cells, encouraging metastasis and the consequence spread of the cancer. Thus, combinations of the present invention can be utilized to treat and/or prevent any of the aforementioned angiogenesis disorders, e.g., by inhibiting and/or reducing blood vessel formation ; by inhibiting, blocking, reducing, decreasing, etc. endothelial cell proliferation or other types involved in angiogenesis, as well as causing cell death or apoptosis of such cell types.
Dose and administration Component A
Based upon standard laboratory techniques known to evaluate compounds useful for the treatment of hyper-proliferative disorders and angiogenic disorders, by standard toxicity tests and by standard pharmacological assays for the determination of treatment of the conditions identified above in mammals, and by comparison of these results with the results of known medicaments that are used to treat these conditions, the effective dosage of the compounds of this invention can readily be determined for treatment of each desired indication. The amount of the active ingredients to be administered in the treatment of one of these conditions can vary widely according to such considerations as the particular compound and dosage unit employed, the mode of administration, the period of treatment, the age and sex of the patient treated, and the nature and extent of the condition treated.
The total amount of the active ingredients to be administered will generally range from about 0.001 mg/kg to about 200 mg/kg body weight per day, and preferably from about 0.01 mg/kg to about 30 mg/kg body weight per day. The total amount of the active ingredients per dose will generally range from about 1 mg to about 500 mg per dose, and preferably from about 20 mg to about 200 mg per dose. Clinically useful dosing schedules of a compound will range from one to three times a day dosing to once every four weeks dosing. In addition, "drug holidays" in which a patient is not dosed with a drug for a certain period of time, may be beneficial to the overall balance between pharmacological effect and tolerability. A unit dosage may contain from about 0.5 mg to about 1500 mg of active ingredient, and can be administered one or more times per day or less than once a day. The average daily dosage for administration by injection, including intravenous, intramuscular, subcutaneous and parenteral injections, and use of infusion techniques will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily rectal dosage regimen will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily vaginal dosage regimen will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily topical dosage regimen will preferably be from 0.1 to 200 mg administered between one to four times daily. The transdermal concentration will preferably be that required to maintain a daily dose of from 0.01 to 200 mg/kg. The average daily inhalation dosage regimen will preferably be from 0.01 to 100 mg/kg of total body weight.
Component B
Based upon standard laboratory techniques known to evaluate compounds useful for the treatment of hyper-proliferative diseases and angiogenic diseases, by standard toxicity tests and by standard pharmacological assays for the determination of treatment of the conditions identified above in mammals, and by comparison of these results with the results of known medicaments that are used to treat these conditions, the effective dosage of the compounds of this invention can readily be determined for treatment of each desired indication. The amount of the active ingredients to be administered in the treatment of one of these conditions can vary widely according to such considerations as the particular component and dosage unit employed, the mode of administration, the period of treatment, the age and sex of the patient treated, and the nature and extent of the condition treated. The total amount of the active ingredients to be administered will generally range from about 0.001 mg/kg to about 200 mg/kg body weight per day, and preferably from about 0.01 mg/kg to about 50 mg/kg body weight per day. Clinically useful dosing schedules of a compound will range from one to three times a day dosing to once every four weeks dosing. In addition, "drug holidays" in which a patient is not dosed with a drug for a certain period of time, may be beneficial to the overall balance between pharmacological effect and tolerability. A unit dosage may contain from about 0.5 mg to about 1500 mg of active ingredient, and can be administered one or more times per day or less than once a day. The average daily dosage for administration by injection, including intravenous, intramuscular, subcutaneous and parenteral injections, and use of infusion techniques will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily rectal dosage regimen will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily vaginal dosage regimen will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily topical dosage regimen will preferably be from 0.1 to 200 mg administered between one to four times daily. The transdermal concentration will preferably be that required to maintain a daily dose of from 0.01 to 200 mg/kg. The average daily inhalation dosage regimen will preferably be from 0.01 to 100 mg/kg of total body weight.
The specific initial and continuing dosage regimen for each patient will vary according to the nature and severity of the condition as determined by the attending diagnostician, the activity of the specific compounds employed, the age and general condition of the patient, time of administration, route of administration, rate of excretion of the drug, drug combinations, and the like. The desired mode of treatment and number of doses of an ATR inhibitor of the present combination or a pharmaceutically acceptable salt, solvate, hydrate or stereoisomer thereof, or a composition thereof can be ascertained by those skilled in the art using conventional tests.
Suitable dose(s), administration regime(s) and administration route(s) for ATR inhibitors may be readily determined by standard techniques known to the skilled person.
The dose(s), administration regime(s) and administration route(s) may have to be adapted according to, inter alia, the indication, the indication stage, the patient age and/or the patient gender, among other factors. Such adaptations can be readily determined by standard techniques known to the skilled person.
For both the Bub1 inhibitors and the ATR inhibitors of the present invention the administered dosage and/or administration regime may be modified, independently of each other or simultaneously, depending on any superior or unexpected results which may be obtained as routinely determined with this invention. For administering the Bub1 inhibitor and the ATR inhibitor, by any of the routes of administration herein discussed, the Bub1 inhibitor can be administered simultaneously with the ATR inhibitor. This can be performed by administering a single formulation which contains both the Bub1 inhibitor and the ATR inhibitor or by administering the Bub1 inihibitor and ATR inhibitor in independent (separate) formulations at the same time (concomittantly) to a patient. Alternatively, the Bub1 inhibitor can be administered in tandem with the ATR inhibitor. The Bub1 inihbitor can be administered prior to the ATR inhibitor. Also, the ATR inhibitor can be administered first followed by adminstration of the Bub1 inihibitor. The choice of sequence administration of the Bub1 inihibitor relative to the ATR inhibitor may vary for different agents, and can be readily determined and, when needed, modified or adapted by the skilled person using techniques readily available in order, for example, to improve the therapeutic effect of the combination. Also, the ATR inhibitor can be administered using any regimen which is conventionally used for these agents.
In another regimen of administration, the Bub1 inihibitor and the ATR inhibitor can be administered once or more times per day on the day(s) of administration.
Any of the routes and regimens of administration may be modified depending on any superior or unexpected results which may be obtained as routinely determined with this invention.

2.3 Methods and parameters
Tumor cells were propagated in a humidified 37°C incubator in their respective growth medium supplemented 10% fetal calf serum. For analysis of combination effects between a compound A and a compound B, cells were plated in 384-well plates at the cell numbers per well as indicated in 0. After 24h, cells were treated with one of the Bub1 kinase inhibitors compound A1 or compound A2 (compound A) and with one of the ATR kinase inhibitors (compound B) Compound B1 , AZD6738, AZ20, VX-970, or Compound 1-1 for single compound treatments (final concentrations see 2.2 Study Design), and in nine different fixed-ratio combinations of compound A (D1 ) and compound B (D2) (0.9xD1 +0.1 xD2, 0.8xD1 +0.2xD2, 0.7xD1 +0.3xD2, 0.6xD1 +0.4xD2, 0.5xD1 +0.5xD2, 0.4xD1 +0.6xD2, 0.3xD1 +0.7xD2, 0.2xD1 +0.8xD2, 0.1 xD1 +0.9xD2). Cell viability was assessed after 96 hour exposure with the Cell Titre-Glo Luminescent Cell Viability Assay (Promega). IC50 values (inhibitory concentration at 50% of maximal effect) were determined by means of a 4 parameter fit on measurement data which were normalized to vehicle (DMSO) treated cells (=100%) and measurement readings taken immediately before compound exposure (=0%). IC50 isobolograms were plotted with the actual concentrations of the two compounds on the x- and y-axis, and the combination index (CI) was calculated according to the median-effect model of Chou- Talalay [Chou T.C. Pharmacol. Rev. 58, 621 , 2006]. A CI of <0.8 was defined as more than additive (synergistic) interaction, and a CI of >1 .2 was defined as antagonistic interaction.

3. Conclusions:
In summary, in the present studies the combination of Bub1 kinase inhibitors compound A1 and compound A2 with ATR inhibitors compound 1-1 , AZ20, VX-970, AZD-6738 and compound B1 , in proliferation assays of human carcinoma cells showed the utility of the present invention.
Bub1 kinase inhibitor COMPOUND A1 showed more than additive (CI50 <0.8) or additive (0.8< CI50 ≤1 .2) interaction with the five ATR inhibitors COMPOUND B1 , AZD6738, AZ20, VX-970 and Compound 1-1 in proliferation assays with ATM-proficient human carcinoma cells representing breast, prostate, lung, and colorectal cancer. In the ATM- or ATM-signaling-deficient cell lines HT-144 and GRANT-519, the combination of the Bub1 kinase inhibitor with an ATR kinase inhibitor was antagonistic which is in line with the proposed role of Bub1 kinase downstream of ATM in DNA damage signaling (Yang ei a/. DNA Repair 1 1 , 185, 2012).
Bub1 kinase inhibitor compound A2 showed more than additive (CI50 <0.8) interaction with the ATR inhibitors compound B1 , AZD6738, and Compound 1-1 in proliferation assays with ATM-proficient human breast carcinoma cells.
These results demonstrate that combination of Bub1 kinase inhibitors with ATR inhibitors can result in more than additive anti-proliferative (synergistic) efficacy in tumor cells, particularly in ATM-proficient tumor cells which express biologically functional ATM protein, and warrant further clinical evaluation of this promising combination therapy for the treatment of cancer.
