BICYCLIC AMINES AS CDK2 INHIBITORS This application claims the benefit of priority of U.S. Prov. Appln. No. 62/914,114, filed October 11, 2019, which is incorporated by reference in its entirety. SEQUENCE LISTING The instant application contains a Sequence Listing which has been filed electronically in ASCII format and is hereby incorporated by reference in its entirety. Said ASCII copy, created on October 2, 2020, is named 20443- 0634WO1_SL.txt and is 15.3 kilobytes in size. TECHNICAL FIELD This application is directed to bicyclic amines which inhibit cyclin-dependent kinase 2 (CDK2) and are useful for treating cancer. BACKGROUND Cyclin-dependent kinases (CDKs) are a family of serine/threonine kinases. Heterodimerized with regulatory subunits known as cyclins, CDKs become fully activated and regulate key cellular processes including cell cycle progression and cell division (Morgan, D. O., Annu Rev Cell Dev Biol, 1997.13: 261-91). Uncontrolled proliferation is a hallmark of cancer cells. The deregulation of the CDK activity is associated with abnormal regulation of cell-cycle, and is detected in virtually all forms of human cancers (Sherr, C. J., Science, 1996.274(5293): 1672-7). CDK2 is of particular interest because deregulation of CDK2 activity occurs frequently in a variety of human cancers. CDK2 plays a crucial role in promoting G1/S transition and S phase progression. In complex with cyclin E (CCNE), CDK2 phosphorylates retinoblastoma pocket protein family members (p107, p130, pRb), leading to de-repression of E2F transcription factors, expression of G1/S transition related genes and transition from G1 to S phase (Henley, S.A. and F.A. Dick, Cell Div, 2012, 7(1): p.10). This in turn enables activation of CDK2/cyclin A, which phosphorylates endogenous substrates that permit DNA synthesis, replication and centrosome duplication (Ekholm, S.V. and S.I. Reed, Curr Opin Cell Biol, 2000. 12(6): 676-84). It has been reported that the CDK2 pathway influences tumorigenesis mainly through amplification and/or overexpression of CCNE1 and mutations that inactivate CDK2 endogenous inhibitors (e.g., p27), respectively (Xu, X., et al., Biochemistry, 1999.38(27): 8713-22). CCNE1 copy-number gain and overexpression have been identified in ovarian, gastric, endometrial, breast and other cancers and been associated with poor outcomes in these tumors (Keyomarsi, K., et al., N Engl J Med, 2002.347(20): 1566- 75; Nakayama, N., et al., Cancer, 2010.116(11): 2621-34; Au-Yeung, G., et al., Clin Cancer Res, 2017.23(7): 1862-1874; Rosen, D.G., et al., Cancer, 2006.106(9): 1925- 32). Amplification and/or overexpression of CCNE1 also reportedly contribute to trastuzumab resistance in HER2+ breast cancer and resistance to CDK4/6 inhibitors in estrogen receptor-positive breast cancer (Scaltriti, M., et al., Proc Natl Acad Sci U S A, 2011.108(9): 3761-6; Herrera-Abreu, M.T., et al., Cancer Res, 2016.76(8): 2301-13). Various approaches targeting CDK2 have been shown to induce cell cycle arrest and tumor growth inhibition (Chen, Y.N., et al., Proc Natl Acad Sci U S A, 1999.96(8): 4325-9; Mendoza, N., et al., Cancer Res, 2003.63(5): 1020-4). Inhibition of CDK2 also reportedly restores sensitivity to trastuzumab treatment in resistant HER2+ breast tumors in a preclinical model (Scaltriti, supra). These data provide a rationale for considering CDK2 as a potential target for new drug development in cancer associated with deregulated CDK2 activity. In the last decade there has been increasing interest in the development of CDK selective inhibitors. Despite significant efforts, there are no approved agents targeting CDK2 to date (Cicenas, J., et al., Cancers (Basel), 2014.6(4): p.2224-42). Therefore it remains a need to discover CDK inhibitors having novel activity profiles, in particular those targeting CDK2. This application is directed to this need and others.

In some embodiments, X is N; and Y is C. In some embodiments, X is C; and Y is N. In some embodiments, Z is N, X is N, and Y is C. In some embodiments, Z is N, X is C, and Y is N. In some embodiments, Z is CR 2 , X is N, and Y is C. In some embodiments, Z is CR 2 , X is C, and Y is N. In some embodiments, 1, 2, 3, 4, 5, 6, 7, or 8 hydrogen atoms, attached to carbon atoms of “alkyl”, “alkenyl”, “alkynyl”, “aryl”, “phenyl”, “cycloalkyl”, “heterocycloalkyl”, or “heteroaryl” substituents or “-C 1-4 alkyl-” and “alkylene” linking groups, as described herein, are optionally replaced by deuterium atoms. It is further appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, can also be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, can also be provided separately or in any suitable subcombination. At various places in the present specification, divalent linking substituents are described. Unless otherwise specified, it is specifically intended that each divalent linking substituent include both the forward and backward forms of the linking substituent. For example, -NR(CR’R’’)n- includes both -NR(CR’R’’)n- and - (CR’R’’)nNR-. Where the structure clearly requires a linking group, the Markush variables listed for that group are understood to be linking groups. The term “n-membered” where n is an integer typically describes the number of ring-forming atoms in a moiety where the number of ring-forming atoms is n. For example, piperidinyl is an example of a 6-membered heterocycloalkyl ring, pyrazolyl is an example of a 5-membered heteroaryl ring, pyridyl is an example of a 6- membered heteroaryl ring, and 1,2,3,4-tetrahydro-naphthalene is an example of a 10- membered cycloalkyl group. As used herein, the phrase “optionally substituted” means unsubstituted or substituted. The substituents are independently selected, and substitution may be at any chemically accessible position. As used herein, the term “substituted” means that a hydrogen atom is removed and replaced by a substituent. A single divalent substituent, e.g., oxo, can replace two hydrogen atoms. It is to be understood that substitution at a given atom is limited by valency, that the designated atom’s normal valency is not exceeded, and that the substitution results in a stable compound. As used herein, the term “independently selected from” means that each occurrence of a variable or substituent are independently selected at each occurrence from the applicable list. As used herein, the phrase “each ‘variable’ is independently selected from” means substantially the same as wherein “at each occurrence ‘variable’ is selected from.” When any variable (e.g., R G ) occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 1, 2, 3, or 4 independently selected R G substituents, then said group may optionally be substituted with up to four R G groups and R G at each occurrence is selected independently from the definition of R G . In some embodiments, when an optionally multiple substituent is designated in the form: then it is to be understood that substituent R can occur p number of times on the ring, and R can be a different moiety at each occurrence. It is to be understood that each R group may replace any hydrogen atom attached to a ring atom, including one or both of the (CH 2 ) n hydrogen atoms. Further, in the above example, should the variable Q be defined to include hydrogens, such as when Q is said to be CH 2 , NH, etc., any floating substituent such as R in the above example, can replace a hydrogen of the Q variable as well as a hydrogen in any other non-variable component of the ring.

Unless otherwise indicated, these rings can be attached to any ring member provided that the valency of the atom is not exceeded. For example, an azetidine ring may be attached at any position of the ring, whereas a pyridin-3-yl ring is attached at the 3-position. The compounds described herein can be asymmetric (e.g., having one or more stereocenters). All stereoisomers, such as enantiomers and diastereomers, are intended unless otherwise indicated. Compounds of the present disclosure that contain asymmetrically substituted carbon atoms can be isolated in optically active or racemic forms. Methods on how to prepare optically active forms from optically inactive starting materials are known in the art, such as by resolution of racemic mixtures or by stereoselective synthesis. Many geometric isomers of olefins, C=N double bonds, and the like can also be present in the compounds described herein, and all such stable isomers are contemplated in the present invention. Cis and trans geometric isomers of the compounds of the present disclosure are described and may be isolated as a mixture of isomers or as separated isomeric forms. In some embodiments, the compound has the (R)-configuration. In some embodiments, the compound has the (S)-configuration. The Formulas (e.g., Formula (I), (II), etc.) provided herein include stereoisomers of the compounds. Resolution of racemic mixtures of compounds can be carried out by any of numerous methods known in the art. An example method includes fractional recrystallization using a chiral resolving acid which is an optically active, salt-forming organic acid. Suitable resolving agents for fractional recrystallization methods are, for example, optically active acids, such as the D and L forms of tartaric acid, diacetyltartaric acid, dibenzoyltartaric acid, mandelic acid, malic acid, lactic acid or the various optically active camphorsulfonic acids such as β-camphorsulfonic acid. Other resolving agents suitable for fractional crystallization methods include stereoisomerically pure forms of α-methylbenzylamine (e.g., S and R forms, or diastereomerically pure forms), 2-phenylglycinol, norephedrine, ephedrine, N- methylephedrine, cyclohexylethylamine, 1,2-diaminocyclohexane, and the like. Resolution of racemic mixtures can also be carried out by elution on a column packed with an optically active resolving agent (e.g., dinitrobenzoylphenylglycine). Suitable elution solvent composition can be determined by one skilled in the art. Compounds provided herein also include tautomeric forms. Tautomeric forms result from the swapping of a single bond with an adjacent double bond together with the concomitant migration of a proton. Tautomeric forms include prototropic tautomers which are isomeric protonation states having the same empirical formula and total charge. Example prototropic tautomers include ketone – enol pairs, amide- imidic acid pairs, lactam – lactim pairs, enamine – imine pairs, and annular forms where a proton can occupy two or more positions of a heterocyclic system, for example, 1H- and 3H-imidazole, 1H-, 2H- and 4H- 1,2,4-triazole, 1H- and 2H- isoindole, 2-hydroxypyridine and 2-pyridone, and 1H- and 2H-pyrazole. Tautomeric forms can be in equilibrium or sterically locked into one form by appropriate substitution. All compounds, and pharmaceutically acceptable salts thereof, can be found together with other substances such as water and solvents (e.g., hydrates and solvates) or can be isolated. In some embodiments, preparation of compounds can involve the addition of acids or bases to affect, for example, catalysis of a desired reaction or formation of salt forms such as acid addition salts. In some embodiments, the compounds provided herein, or salts thereof, are substantially isolated. By “substantially isolated” is meant that the compound is at least partially or substantially separated from the environment in which it was formed or detected. Partial separation can include, for example, a composition enriched in the compounds provided herein. Substantial separation can include compositions containing at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, at least about 95%, at least about 97%, or at least about 99% by weight of the compounds provided herein, or salt thereof. Methods for isolating compounds and their salts are routine in the art. The term “compound” as used herein is meant to include all stereoisomers, geometric isomers, tautomers, and isotopes of the structures depicted. Compounds herein identified by name or structure as one particular tautomeric form are intended to include other tautomeric forms unless otherwise specified. The phrase “pharmaceutically acceptable” is employed herein to refer to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio. The present application also includes pharmaceutically acceptable salts of the compounds described herein. As used herein, “pharmaceutically acceptable salts” refers to derivatives of the disclosed compounds wherein the parent compound is modified by converting an existing acid or base moiety to its salt form. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. The pharmaceutically acceptable salts of the present disclosure include the conventional non-toxic salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. The pharmaceutically acceptable salts of the present disclosure can be synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, non-aqueous media like ether, ethyl acetate, alcohols (e.g., methanol, ethanol, iso-propanol, or butanol) or acetonitrile (ACN) are preferred. Lists of suitable salts are found in Remington’s Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., 1985, p.1418 and Journal of Pharmaceutical Science, 66, 2 (1977), each of which is incorporated herein by reference in its entirety. Synthesis As will be appreciated by those skilled in the art, the compounds provided herein, including salts and stereoisomers thereof, can be prepared using known organic synthesis techniques and can be synthesized according to any of numerous possible synthetic routes, such as those provided in the Schemes below. The reactions for preparing compounds described herein can be carried out in suitable solvents which can be readily selected by one of skill in the art of organic synthesis. Suitable solvents can be substantially non-reactive with the starting materials (reactants), the intermediates or products at the temperatures at which the reactions are carried out, e.g., temperatures which can range from the solvent’s freezing temperature to the solvent’s boiling temperature. A given reaction can be carried out in one solvent or a mixture of more than one solvent. Depending on the particular reaction step, suitable solvents for a particular reaction step can be selected by the skilled artisan. The expressions, “ambient temperature” or “room temperature” or “r.t.” as used herein, are understood in the art, and refer generally to a temperature, e.g., a reaction temperature, that is about the temperature of the room in which the reaction is carried out, for example, a temperature from about 20 ºC to about 30 ºC. Preparation of compounds of the invention can involve the protection and deprotection of various chemical groups. The need for protection and deprotection, and the selection of appropriate protecting groups, can be readily determined by one skilled in the art. The chemistry of protecting groups is described, e.g., in Kocienski, Protecting Groups, (Thieme, 2007); Robertson, Protecting Group Chemistry, (Oxford University Press, 2000); Smith et al., March’s Advanced Organic Chemistry: Reactions, Mechanisms, and Structure, 6 th Ed. (Wiley, 2007); Peturssion et al., "Protecting Groups in Carbohydrate Chemistry," J. Chem. Educ., 1997, 74(11), 1297; and Wuts et al., Protective Groups in Organic Synthesis, 4th Ed., (Wiley, 2006). Reactions can be monitored according to any suitable method known in the art. For example, product formation can be monitored by spectroscopic means, such as nuclear magnetic resonance spectroscopy (e.g., 1 H or 13 C), infrared spectroscopy, spectrophotometry (e.g., UV-visible), mass spectrometry or by chromatographic methods such as high performance liquid chromatography (HPLC), liquid chromatography-mass spectroscopy (LCMS), or thin layer chromatography (TLC). Compounds can be purified by those skilled in the art by a variety of methods, including high performance liquid chromatography (HPLC) and normal phase silica chromatography. The Schemes below provide general guidance in connection with preparing the compounds of the invention. One skilled in the art would understand that the preparations shown in the Schemes can be modified or optimized using general knowledge of organic chemistry to prepare various compounds of the invention.

Combination Therapies I. Cancer therapies Cancer cell growth and survival can be impacted by dysfunction in multiple signaling pathways. Thus, it is useful to combine different enzyme/protein/receptor inhibitors, exhibiting different preferences in the targets which they modulate the activities of, to treat such conditions. Targeting more than one signaling pathway (or more than one biological molecule involved in a given signaling pathway) may reduce the likelihood of drug-resistance arising in a cell population, and/or reduce the toxicity of treatment.

Examples of IDO1 inhibitors include epacadostat, NLG919, BMS-986205, PF-06840003, IOM2983, RG-70099 and LY338196. As provided throughout, the additional compounds, inhibitors, agents, etc. can be combined with the present compound in a single or continuous dosage form, or they can be administered simultaneously or sequentially as separate dosage forms. Pharmaceutical Formulations and Dosage Forms When employed as pharmaceuticals, the compounds of the disclosure can be administered in the form of pharmaceutical compositions. These compositions can be prepared in a manner well known in the pharmaceutical art, and can be administered by a variety of routes, depending upon whether local or systemic treatment is desired and upon the area to be treated. Administration may be topical (including transdermal, epidermal, ophthalmic and to mucous membranes including intranasal, vaginal and rectal delivery), pulmonary (e.g., by inhalation or insufflation of powders or aerosols, including by nebulizer; intratracheal or intranasal), oral, or parenteral. Parenteral administration includes intravenous, intraarterial, subcutaneous, intraperitoneal intramuscular or injection or infusion; or intracranial, e.g., intrathecal or intraventricular, administration. Parenteral administration can be in the form of a single bolus dose, or may be, for example, by a continuous perfusion pump. Pharmaceutical compositions and formulations for topical administration may include transdermal patches, ointments, lotions, creams, gels, drops, suppositories, sprays, liquids and powders. Conventional pharmaceutical carriers, aqueous, powder or oily bases, thickeners and the like may be necessary or desirable. This disclosure also includes pharmaceutical compositions which contain, as the active ingredient, the compound of the disclosure or a pharmaceutically acceptable salt thereof, in combination with one or more pharmaceutically acceptable carriers (excipients). In some embodiments, the composition is suitable for topical administration. In making the compositions of the disclosure, the active ingredient is typically mixed with an excipient, diluted by an excipient or enclosed within such a carrier in the form of, for example, a capsule, sachet, paper, or other container. When the excipient serves as a diluent, it can be a solid, semi-solid, or liquid material, which acts as a vehicle, carrier or medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, suppositories, sterile injectable solutions, and sterile packaged powders. In preparing a formulation, the active compound can be milled to provide the appropriate particle size prior to combining with the other ingredients. If the active compound is substantially insoluble, it can be milled to a particle size of less than 200 mesh. If the active compound is substantially water soluble, the particle size can be adjusted by milling to provide a substantially uniform distribution in the formulation, e.g., about 40 mesh. The compounds of the disclosure may be milled using known milling procedures such as wet milling to obtain a particle size appropriate for tablet formation and for other formulation types. Finely divided (nanoparticulate) preparations of the compounds of the disclosure can be prepared by processes known in the art, e.g., see International App. No. WO 2002/000196. Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, water, syrup, and methyl cellulose. The formulations can additionally include: lubricating agents such as talc, magnesium stearate, and mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl- and propylhydroxy-benzoates; sweetening agents; and flavoring agents. The compositions of the disclosure can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the patient by employing procedures known in the art. The compositions can be formulated in a unit dosage form, each dosage containing from about 5 to about 1000 mg (1 g), or more, such as about 100 to about 500 mg, of the active ingredient. The term “unit dosage forms” refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient. In some embodiments, the compositions of the disclosure contain from about 5 to about 50 mg of the active ingredient. One having ordinary skill in the art will appreciate that this embodies compositions containing about 5 to about 10, about 10 to about 15, about 15 to about 20, about 20 to about 25, about 25 to about 30, about 30 to about 35, about 35 to about 40, about 40 to about 45, or about 45 to about 50 mg of the active ingredient. In some embodiments, the compositions of the disclosure contain from about 50 to about 500 mg of the active ingredient. One having ordinary skill in the art will appreciate that this embodies compositions containing about 50 to about 100, about 100 to about 150, about 150 to about 200, about 200 to about 250, about 250 to about 300, about 350 to about 400, or about 450 to about 500 mg of the active ingredient. In some embodiments, the compositions of the disclosure contain from about 500 to about 1000 mg of the active ingredient. One having ordinary skill in the art will appreciate that this embodies compositions containing about 500 to about 550, about 550 to about 600, about 600 to about 650, about 650 to about 700, about 700 to about 750, about 750 to about 800, about 800 to about 850, about 850 to about 900, about 900 to about 950, or about 950 to about 1000 mg of the active ingredient. Similar dosages may be used of the compounds described herein in the methods and uses of the disclosure. The active compound can be effective over a wide dosage range and is generally administered in a pharmaceutically effective amount. It will be understood, however, that the amount of the compound actually administered will usually be determined by a physician, according to the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual patient, the severity of the patient’s symptoms, and the like. For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound of the present disclosure. When referring to these preformulation compositions as homogeneous, the active ingredient is typically dispersed evenly throughout the composition so that the composition can be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. This solid preformulation is then subdivided into unit dosage forms of the type described above containing from, for example, about 0.1 to about 1000 mg of the active ingredient of the present disclosure. The tablets or pills of the present disclosure can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate. The liquid forms in which the compounds and compositions of the present disclosure can be incorporated for administration orally or by injection include aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles. Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. In some embodiments, the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions can be nebulized by use of inert gases. Nebulized solutions may be breathed directly from the nebulizing device or the nebulizing device can be attached to a face mask, tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions can be administered orally or nasally from devices which deliver the formulation in an appropriate manner. Topical formulations can contain one or more conventional carriers. In some embodiments, ointments can contain water and one or more hydrophobic carriers selected from, for example, liquid paraffin, polyoxyethylene alkyl ether, propylene glycol, white Vaseline, and the like. Carrier compositions of creams can be based on water in combination with glycerol and one or more other components, e.g., glycerinemonostearate, PEG-glycerinemonostearate and cetylstearyl alcohol. Gels can be formulated using isopropyl alcohol and water, suitably in combination with other components such as, for example, glycerol, hydroxyethyl cellulose, and the like. In some embodiments, topical formulations contain at least about 0.1, at least about 0.25, at least about 0.5, at least about 1, at least about 2, or at least about 5 wt % of the compound of the disclosure. The topical formulations can be suitably packaged in tubes of, for example, 100 g which are optionally associated with instructions for the treatment of the select indication, e.g., psoriasis or other skin condition. The amount of compound or composition administered to a patient will vary depending upon what is being administered, the purpose of the administration, such as prophylaxis or therapy, the state of the patient, the manner of administration, and the like. In therapeutic applications, compositions can be administered to a patient already suffering from a disease in an amount sufficient to cure or at least partially arrest the symptoms of the disease and its complications. Effective doses will depend on the disease condition being treated as well as by the judgment of the attending clinician depending upon factors such as the severity of the disease, the age, weight and general condition of the patient, and the like. The compositions administered to a patient can be in the form of pharmaceutical compositions described above. These compositions can be sterilized by conventional sterilization techniques, or may be sterile filtered. Aqueous solutions can be packaged for use as is, or lyophilized, the lyophilized preparation being combined with a sterile aqueous carrier prior to administration. The pH of the compound preparations typically will be between 3 and 11, more preferably from 5 to 9 and most preferably from 7 to 8. It will be understood that use of certain of the foregoing excipients, carriers, or stabilizers will result in the formation of pharmaceutical salts. The therapeutic dosage of a compound of the present disclosure can vary according to, for example, the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of a compound of the disclosure in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds of the disclosure can be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w/v of the compound for parenteral administration. Some typical dose ranges are from about 1 µg/kg to about 1 g/kg of body weight per day. In some embodiments, the dose range is from about 0.01 mg/kg to about 100 mg/kg of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems. The compositions of the disclosure can further include one or more additional pharmaceutical agents such as a chemotherapeutic, steroid, anti-inflammatory compound, or immunosuppressant, examples of which are listed herein. Labeled Compounds and Assay Methods Another aspect of the present disclosure relates to labeled compounds of the disclosure (radio-labeled, fluorescent-labeled, etc.) that would be useful not only in imaging techniques but also in assays, both in vitro and in vivo, for localizing and quantitating CDK2 in tissue samples, including human, and for identifying CDK2 activators by inhibition binding of a labeled compound. Substitution of one or more of the atoms of the compounds of the present disclosure can also be useful in generating differentiated ADME (Adsorption, Distribution, Metabolism and Excretion.) Accordingly, the present disclosure includes CDK2 assays that contain such labeled or substituted compounds. The present disclosure further includes isotopically-labeled compounds of the disclosure. An “isotopically” or “radio-labeled” compound is a compound of the disclosure where one or more atoms are replaced or substituted by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature (i.e., naturally occurring). Suitable radionuclides that may be incorporated in compounds of the present disclosure include but are not limited to 2 H (also written as D for deuterium), 3 H (also written as T for tritium), 11 C, 13 C, 14 C, 13 N, 15 N, 15 O, 17 O, 18 O, 18 F, 35 S, 36 Cl, 82 Br, 75 Br, 76 Br, 77 Br, 123 I, 124 I, 125 I and 131 I. For example, one or more hydrogen atoms in a compound of the present disclosure can be replaced by deuterium atoms (e.g., one or more hydrogen atoms of a C 1-6 alkyl group of Formula (I) can be optionally substituted with deuterium atoms, such as –CD 3 being substituted for –CH 3 ). In some embodiments, alkyl groups of the disclosed Formulas (e.g., Formula (I)) can be perdeuterated. One or more constituent atoms of the compounds presented herein can be replaced or substituted with isotopes of the atoms in natural or non-natural abundance. In some embodiments, the compound includes at least one deuterium atom. For example, one or more hydrogen atoms in a compound presented herein can be replaced or substituted by deuterium (e.g., one or more hydrogen atoms of a C 1-6 alkyl group can be replaced by deuterium atoms, such as –CD 3 being substituted for –CH 3 ). In some embodiments, the compound includes two or more deuterium atoms. In some embodiments, the compound includes 1-2, 1-3, 1-4, 1-5, or 1-6 deuterium atoms. In some embodiments, all of the hydrogen atoms in a compound can be replaced or substituted by deuterium atoms. In some embodiments, 1, 2, 3, 4, 5, 6, 7, or 8 hydrogen atoms, attached to carbon atoms of alkyl, alkenyl, alkynyl, aryl, phenyl, cycloalkyl, heterocycloalkyl, or heteroaryl substituents or -C 1-4 alkyl-, alkylene, alkenylene and alkynylene linking groups, as described herein, are optionally replaced by deuterium atoms. Synthetic methods for including isotopes into organic compounds are known in the art (Deuterium Labeling in Organic Chemistry by Alan F. Thomas, New York, N.Y., Appleton-Century-Crofts, 1971; The Renaissance of H/D Exchange by Jens Atzrodt, Volker Derdau, Thorsten Fey and Jochen Zimmermann, Angew. Chem. Int. Ed.2007, 7744-7765; The Organic Chemistry of Isotopic Labelling by James R. Hanson, Royal Society of Chemistry, 2011). Isotopically labeled compounds can be used in various studies such as NMR spectroscopy, metabolism experiments, and/or assays. Substitution with heavier 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 may be preferred in some circumstances. (see e.g., A. Kerekes et al. J. Med. Chem.2011, 54, 201-210; R. Xu et al. J. Label Compd. Radiopharm.2015, 58, 308-312). In particular, substitution at one or more metabolism sites may afford one or more of the therapeutic advantages. The radionuclide that is incorporated in the instant radio-labeled compounds will depend on the specific application of that radio-labeled compound. For example, for in vitro CDK2 labeling and competition assays, compounds that incorporate 3 H, 14 C, 82 Br, 125 I, 131 I, or 35 S can be useful. For radio-imaging applications 11 C, 18 F, 125 I, 123 I, 124 I, 131 I, 75 Br, 76 Br, or 77 Br can be useful. It is understood that a “radio-labeled” or “labeled compound” is a compound that has incorporated at least one radionuclide. In some embodiments, the radionuclide is selected from the group consisting of 3 H, 14 C, 125 I, 35 S, and 82 Br. The present disclosure can further include synthetic methods for incorporating radio-isotopes into compounds of the disclosure. Synthetic methods for incorporating radio-isotopes into organic compounds are well known in the art, and one of ordinary skill in the art will readily recognize the methods applicable for the compounds of disclosure. A labeled compound of the disclosure can be used in a screening assay to identify/evaluate compounds. For example, a newly synthesized or identified compound (i.e., test compound) which is labeled can be evaluated for its ability to bind and activate CDK2 by monitoring its concentration variation when contacting with CDK2, through tracking of the labeling. For example, a test compound (labeled) can be evaluated for its ability to reduce binding of another compound which is known to inhibit CDK2 (i.e., standard compound). Accordingly, the ability of a test compound to compete with the standard compound for binding to CDK2 directly correlates to its binding affinity. Conversely, in some other screening assays, the standard compound is labeled and test compounds are unlabeled. Accordingly, the concentration of the labeled standard compound is monitored in order to evaluate the competition between the standard compound and the test compound, and the relative binding affinity of the test compound is thus ascertained. Kits The present disclosure also includes pharmaceutical kits useful, for example, in the treatment or prevention of CDK2-associated diseases or disorders (such as, e.g., cancer, an inflammatory disease, a cardiovascular disease, or a neurodegenerative disease) which include one or more containers containing a pharmaceutical composition comprising a therapeutically effective amount of a compound of the disclosure. Such kits can further include, if desired, one or more of various conventional pharmaceutical kit components, such as, for example, containers with one or more pharmaceutically acceptable carriers, additional containers, etc., as will be readily apparent to those skilled in the art. Instructions, either as inserts or as labels, indicating quantities of the components to be administered, guidelines for administration, and/or guidelines for mixing the components, can also be included in the kit. Biomarkers and Pharmacodynamics Markers The disclosure further provides predictive markers (e.g., biomarkers and pharmacodynamic markers, e.g., gene copy number, gene sequence, expression levels, or phosphorylation levels) to identify those human subjects having, suspected of having, or at risk of developing a disease or disorder associated with CDK2 for whom administering a CDK2 inhibitor (“a CDK2 inhibitor” as used herein refers to a compound of the disclosure, or a pharmaceutically acceptable salt thereof) is likely to be effective. The disclosure also provides pharmacodynamic markers (e.g., phosphorylation levels) to identify those human subjects having, suspected of having, or at risk of developing a disease or disorder associated with CDK2 whom are responding to a CDK2 inhibitor. The use of CCNE1, p16, and Rb S780 is further described in WO 2020/168178 (and in U.S. Appln. No.16/791,561), the figures and disclosure of which is incorporated by reference herein in its entirety. The methods are based, at least in part, on the discovery that the functional status of cyclin dependent kinase inhibitor 2A (“CDKN2A”; also referred to as “p16”) is a biomarker for predicting sensitivity to CDK2-targeting therapies in G1/S-specific cyclin-E1- (“CCNE1-”) amplified cells suitable for use in patient stratification. In addition, the present invention is based, at least in part, on the discovery that, in CCNE1-amplified cell lines, the level of human retinoblastoma associated protein (“Rb”) phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3 is a pharmacodynamic marker for CDK2 activity and is suitable for use in measuring CDK2 enzymatic activity in cellular assay or preclinical and clinical applications, such as, e.g., monitoring the progress of or responsiveness to treatment with a CDK2 inhibitor. CCNE1 and p16 CCNE1 and p16 have been identified in the Examples as genes, in combination, useful in predicting responsiveness (e.g., improvement in disease as evidenced by disease remission/resolution) of a subject having a disease or disorder associated with CDK2 to a CDK2 inhibitor. p16 (also known as cyclin-dependent kinase inhibitor 2A, cyclin-dependent kinase 4 inhibitor A, multiple tumor suppressor 1, and p16-INK4a) acts as a negative regulator of the proliferation of normal cells by interacting with CDK4 and CDK6. p16 is encoded by the cyclin dependent kinase inhibitor 2A (“CDKN2A”) gene (GenBank Accession No. NM_000077). The cytogenic location of the CDKN2A gene is 9p21.3, which is the short (p) arm of chromosome 9 at position 21.3. The molecular location of the CDKN2A gene is base pairs 21,967,752 to 21,995,043 on chromosome 9 (Homo sapiens Annotation Release 109, GRCh38.p12). Genetic and epigenetic abnormalities in the gene encoding p16 are believed to lead to escape from senescence and cancer formation (Okamoto et al., 1994, PNAS 91(23):11045-9). Nonlimiting examples of genetic abnormalities in the gene encoding p16 are described in Table A, below. The amino acid sequence of human p16 is provided below (GenBank Accession No. NP_000068 / UniProtKB Accession No. P42771): 1 MEPAAGSSME PSADWLATAA ARGRVEEVRA LLEAGALPNA PNSYGRRPIQ VMMMGSARVA 61 ELLLLHGAEP NCADPATLTR PVHDAAREGF LDTLVVLHRA GARLDVRDAW GRLPVDLAEE 121 LGHRDVARYL RAAAGGTRGS NHARIDAAEG PSDIPD (SEQ ID NO:1). CCNE1 is a cell cycle factor essential for the control of the cell cycle at the G1/S transition (Ohtsubo et al., 1995, Mol. Cell. Biol.15:2612-2624). CCNE1 acts as a regulatory subunit of CDK2, interacting with CDK2 to form a serine/threonine kinase holoenzyme complex. The CCNE1 subunit of this holoenzyme complex provides the substrate specificity of the complex (Honda et al., 2005, EMBO 24:452- 463). CCNE1 is encoded by the cyclin E1 (“CCNE1”) gene (GenBank Accession No. NM_001238). The amino acid sequence of human CCNE1 is provided below (GenBank Accession No. NP_001229 / UniProtKB Accession No. P24864): 1 mprerrerda kerdtmkedg gaefsarsrk rkanvtvflq dpdeemakid rtardqcgsq 61 pwdnnavcad pcsliptpdk edddrvypns tckpriiaps rgsplpvlsw anreevwkim 121 lnkektylrd qhfleqhpll qpkmrailld wlmevcevyk lhretfylaq dffdrymatq 181 envvktllql igisslfiaa kleeiyppkl hqfayvtdga csgdeiltme lmimkalkwr 241 lspltivswl nvymqvayln dlhevllpqy pqqifiqiae lldlcvldvd clefpygila 301 asalyhfsss elmqkvsgyq wcdiencvkw mvpfamvire tgssklkhfr gvadedahni 361 qthrdsldll dkarakkaml seqnrasplp sglltppqsg kkqssgpema (SEQ ID NO:2). The Examples demonstrate CDK2-knockdown inhibits proliferation of CCNE1-amplified cell lines, but not of CCNE1-non-amplified cell lines. Conversely, the Examples show that CDK4/6 inhibition inhibits proliferation of CCNE1-non- amplified cell lines, but not of CCNE1-amplified cell lines. The Examples further demonstrate that presence of a normal (e.g., non-mutated or non-deleted) p16 gene is required for the observed inhibition of cell proliferation in CCNE1-amplified cells treated with a CDK2-inhibitor. Accordingly, CCNE1 and p16 are, together, a combination biomarker: cells that respond to treatment with a CDK2 inhibitor display an amplification of the CCNE1 gene and/or an expression level of CCNE1 that is higher than a control expression level of CCNE1, and have a nucleotide sequence (e.g., a gene or an mRNA) that encodes the p16 protein (e.g., a p16 protein comprising the amino acid sequence of SEQ ID NO:1) and/or have p16 protein present, while control cells that do not respond to treatment with a CDK2 inhibitor do not have an amplification of the CCNE1 gene and/or an expression level of CCNE1 that is higher than a control expression level of CCNE1, and tend to have a mutated or deleted gene that encodes the p16 protein and/or lack expression of p16 protein. Thus, the disclosure provides a method of treating a human subject having, suspected of having, or at risk of developing a disease or disorder associated with CDK2, comprising administering to the human subject a CDK2 inhibitor, wherein the human subject has been previously determined to: (i) (a) have a nucleotide sequence encoding a p16 protein comprising the amino acid sequence of SEQ ID NO:1, (b) have a CDKN2A gene lacking one or more inactivating nucleic acid substitutions and/or deletions, and/or (c) express a p16 protein, and (ii) (a) have an amplification of the CCNE1 gene and/or (b) have an expression level of CCNE1 in a biological sample obtained from the human subject that is higher than a control expression level of CCNE1. In certain embodiments, the predictive methods described herein predict that the subject will respond to treatment with the CDK2 inhibitor with at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, at least 98% or 100% accuracy. For example, in some embodiments, if the predictive methods described herein are applied to 10 subjects having, suspected of having, or at risk of developing a disease or disorder associated with CDK2, and 8 of those 10 subjects are predicted to respond to treatment with a CDK2 inhibitor based on a predictive method described herein, and 7 of those 8 subjects do indeed respond to treatment with a CDK2 inhibitor, then the predictive method has an accuracy of 87.5% (7 divided by 8). A subject is considered to respond to the CDK2 inhibitor if the subject shows any improvement in disease status as evidenced by, e.g., reduction or alleviation in symptoms, disease remission/resolution, etc. In some embodiments, the subject has a disease or disorder associated with CDK2. In some embodiments, the human subject has been previously determined to: (i) (a) have a nucleotide sequence encoding a p16 protein comprising the amino acid sequence of SEQ ID NO:1 and/or (b) a CDKN2A gene lacking one or more inactivating nucleic acid substitutions and/or deletions, and (ii) have an amplification of the CCNE1 gene in a biological sample obtained from the human subject. In some embodiments, the CDKN2A gene encodes a protein comprising the amino acid sequence of SEQ ID NO:1. In specific embodiments, the CDKN2A gene encodes a protein comprising the amino acid sequence of SEQ ID NO:1. In specific embodiments, the one or more inactivating nucleic acid substitutions and/or deletions in the CDKN2A gene is as described in Table A. In specific embodiments, the one or more inactivating nucleic acid substitutions and/or deletions in the CDKN2A gene is as described in Yarbrough et al., Journal of the National Cancer Institute, 91(18):1569-1574, 1999; Liggett and Sidransky, Biology of Neoplasia, Journal of Oncology, 16(3):1197-1206, 1998, and Cairns et al., Nature Genetics, 11:210-212, 1995, each of which is incorporated by reference herein in its entirety.

In some embodiments, the CCNE1 gene is amplified to a gene copy number from 3 to 25. In specific embodiments, the CCNE1 gene is amplified to a gene copy number of at least 3. In specific embodiments, the CCNE1 gene is amplified to a gene copy number of at least 5. In specific embodiments, the CCNE1 gene is amplified to a gene copy number of at least 7.

Rb S780 The disclosure also features a method for assessing the CDKN2A gene and the CCNE1 gene, comprising determining, from a biological sample or biological samples obtained from a human subject having a disease or disorder associated with CDK2, (i) (a) the nucleotide sequence of a CDKN2A gene or (b) the presence of a CDKN2A gene lacking one or more inactivating nucleic acid substitutions and/or deletions, and (ii) the copy number of the CCNE1 gene. The disclosure also features a method of evaluating the response of a human subject having, suspected of having, or at risk of developing a disease or disorder associated with CDK2 to a CDK2 inhibitor, comprising: (a) administering a CDK2 inhibitor to the human subject, wherein the human subject has been previously determined to have an amplification of the CCNE1 gene and/or an expression level of CCNE1 that is higher than a control expression level of CCNE1; (b) measuring, in a biological sample of obtained from the subject subsequent to the administering of step (a), the level of retinoblastoma (Rb) protein phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3, wherein a reduced level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3, as compared to a control level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3, is indicative that the human subject responds to the CDK2 inhibitor. In some embodiments, the subject has a disease or disorder associated with CDK2. In some embodiments, the subject is suspected of having or is at risk of developing a disease or disorder associated with CDK2. In some embodiments, the biological sample comprises a blood sample or a tumor biopsy sample. Phosphorylation of Rb at the serine corresponding to amino acid position 780 of SEQ ID NO:3 (referred to herein as “Ser780” or “S780”) has been identified in the Examples as a pharmacodynamic marker useful in assessing responsiveness (e.g., inhibition by CDK2) of a human subject having a disease or disorder having CCNE1 amplification to a CDK2 inhibitor. Rb is a regulator of the cell cycle and acts as a tumor suppressor. Rb is activated upon phosphorylation by cyclin D-CDK4/6 at Ser780 and Ser795 and by cyclin E/CDK2 at Ser807 and Ser811. Rb is encoded by the RB transcriptional corepressor 1 (“RB1”) gene (GenBank Accession No. NM_000321). The amino acid sequence of human Rb is provided below (GenBank Accession No. NP_000312 / UniProtKB Accession No. P06400) (S780 is in bold and underlined): As stated above, the Examples demonstrate CDK2-knockdown inhibits proliferation in CCNE1-amplified cell lines, but not in CCNE1-non-amplified cell lines. The Examples further demonstrate CDK2-knockdown or inhibition blocks Rb phosphorylation at the S780 in CCNE1-amplified cell lines, but not in CCNE1-non- amplified cell lines. Accordingly, Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3 is a pharmacodynamic marker for assessing response to CDK2 inhibition in CCNE1 amplified cancer cells or patients with diseases or disorders having CCNE1 amplification. Thus, provided herein are methods relating to the use of the level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3 in a human subject having, suspected of having, or at risk of developing a disease or disorder associated with CDK2 as a marker for indicating the response of the human subject to a CDK2 inhibitor, wherein the human subject has an increased expression level of CCNE1. Thus, the disclosure features a method for measuring the amount of a protein in a sample, comprising: (a) providing a biological sample obtained from a human subject having a disease or disorder associated with CDK2; and (b) measuring the level of Rb protein phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3 in the biological sample. In some embodiments, the biological sample comprises a blood sample or a tumor biopsy sample. In a specific embodiment, provided herein is a method of evaluating the response of a human subject having, suspected of having, or at risk of developing a disease or disorder associated with CDK2 to a CDK2 inhibitor, comprising: (a) administering a CDK2 inhibitor to the human subject, wherein the human subject has been previously determined to have an amplification of the CCNE1 gene and/or an expression level of CCNE1 that is higher than a control expression level of CCNE1; and (b) measuring, in a biological sample obtained from the human subject subsequent to the administering of step (a), the level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3, wherein a reduced level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3, as compared to a control level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3, is indicative that the human subject responds to the CDK2 inhibitor. In specific embodiments, the human subject has a disease or disorder associated with CDK2. A reduced level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3, as compared to a control level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3, combined with an amplification of the CCNE1 gene and/or an expression level of CCNE1 that is higher than a control expression level of CCNE1, is indicative that a human subject having, suspected of having, or at risk of developing a disease or disorder associated with CDK2 responds to a CDK2 inhibitor. For example, in a subject having an amplification of the CCNE1 gene and/or an expression level of CCNE1 that is higher than a control expression level of CCNE1, a biological sample, obtained from the subject after treatment with a CDK2 inhibitor, having low (e.g., reduced as compared to a control) or undetectable levels of Rb phosphorylation at serine corresponding to amino acid position 780 of SEQ ID NO:3 is indicative that the subject responds to the CDK2 inhibitor. A biological sample, obtained from a subject after administration of a CDK2 inhibitor to the subject, having a reduced level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3, as compared to a control level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3, combined with: (i) an amplification of the CCNE1 gene and/or an expression level of CCNE1 that is higher than a control expression level of CCNE1, and (ii) presence of a CDKN2A gene encoding a p16 protein comprising the amino acid sequence of SEQ ID NO:1, presence of a CDKN2A gene lacking one or more inactivating nucleic acid substitutions and/or deletions, and/or presence of a p16 protein (e.g., a p16 protein comprising the amino acid sequence of SEQ ID NO:1), is indicative that a human subject having, suspected of having, or at risk of developing a disease or disorder associated with CDK2 responds to a CDK2 inhibitor. For example, in a human subject having (i) an amplification of the CCNE1 gene and/or an expression level of CCNE1 that is higher than a control expression level of CCNE1, and (ii) the presence of a CDKN2A gene encoding a p16 protein comprising the amino acid sequence of SEQ ID NO:1, the presence of a CDKN2A gene lacking one or more inactivating nucleic acid substitutions and/or deletions, and/or the presence of a p16 protein (e.g., a p16 protein comprising the amino acid sequence of SEQ ID NO:1), a biological sample, obtained from the human subject after administration of a CDK2 inhibitor to the subject, having low (e.g., reduced as compared to a control) or undetectable levels of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3 is indicative that the human subject responds to the CDK2 inhibitor In some embodiments, the CCNE1 gene is amplified to a gene copy number from 3 to 25. In specific embodiments, the CCNE1 gene is amplified to a gene copy number of at least 3. In specific embodiments, the CCNE1 gene is amplified to a gene copy number of at least 5. In specific embodiments, the CCNE1 gene is amplified to a gene copy number of at least 7. In specific embodiments, the CCNE1 gene is amplified to a gene copy number of at least 10. In specific embodiments, the CCNE1 gene is amplified to a gene copy number of at least 12. In specific embodiments, the CCNE1 gene is amplified to a gene copy number of at least 14. In specific embodiments, the CCNE1 gene is amplified to a gene copy number of at least 21. In specific embodiments, the expression level of CCNE1 is the level of CCNE1 mRNA. In specific embodiments, the expression level of CCNE1 is the level of CCNE1 protein. Controls As described above, the methods related to biomarkers and pharmacodynamic markers can involve, measuring one or more markers (e.g., a biomarker or a pharmacodynamics marker, e.g., the amplification of the CCNE1 gene, the expression level of CCNE1, the presence of a CDKN2A gene encoding a p16 protein comprising the amino acid sequence of SEQ ID NO:1, the presence of a CDKN2A gene lacking one or more inactivating nucleic acid substitutions and/or deletions, the presence of a p16 protein (e.g., a p16 protein comprising the amino acid sequence of SEQ ID NO:1), and Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3) in a biological sample from a human subject having, suspected of having or at risk of developing a disease or disorder associated with CDK2. In specific embodiments, the human subject has a disease or disorder associated with CDK2. In specific embodiments, the human subject is suspected of having or is at risk of developing a disease or disorder associated with CDK2. In certain aspects, the level (e.g., amplification (e.g., for the CCNE1 gene), expression level (e.g., for CCNE1 or p16 protein), or phosphorylation level (e.g., for Rb)) of one or more biomarkers, compared to a control level of the one or more biomarkers, predicts/indicates the response of a human subject to treatment comprising a CDK2 inhibitor. In certain embodiments, when (i) the CCNE1 gene is amplified and/or an expression level of CCNE1 that is higher than a control expression level of CCNE1, and (ii) a CDKN2A gene encoding a p16 protein comprising the amino acid sequence of SEQ ID NO:1 is present, a CDKN2A gene lacking one or more inactivating nucleic acid substitutions and/or deletions is present, and/or a p16 protein (e.g., a p16 protein comprising the amino acid sequence of SEQ ID NO:1) is present, the human subject is identified as likely to respond to a CDK2 inhibitor. In other embodiments, when (i) the CCNE1 gene is amplified and/or an expression level of CCNE1 that is higher than a control expression level of CCNE1, and (ii) in a biological sample from the human subject after the human subject has been administered a CDK2 inhibitor, the level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3 is less than the control level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3, the human subject is identified as responding to a CDK2 inhibitor. In yet another embodiment, when (i) the CCNE1 gene is amplified and/or an expression level of CCNE1 that is higher than a control expression level of CCNE1, (ii) a CDKN2A gene encoding a p16 protein comprising the amino acid sequence of SEQ ID NO:1 is present, a CDKN2A gene lacking one or more inactivating nucleic acid substitutions and/or deletions is present, and/or a p16 protein (e.g., a p16 protein comprising the amino acid sequence of SEQ ID NO:1) is present, and (iii) in a biological sample from the human subject after the human subject has been administered a CDK2 inhibitor, the level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3 is less than the control level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3, the human subject is identified as responding to a CDK2 inhibitor. In this context, the term “control” includes a sample (from the same tissue type) obtained from a human subject who is known to not respond to a CDK2 inhibitor. The term “control” also includes a sample (from the same tissue type) obtained in the past from a human subject who is known to not respond to a CDK2 inhibitor and used as a reference for future comparisons to test samples taken from human subjects for which therapeutic responsiveness is to be predicted. The “control” level (e.g., gene copy number, expression level, or phosphorylation level) for a particular biomarker (e.g., CCNE1, p16, or Rb phosphorylation) in a particular cell type or tissue may be pre-established by an analysis of biomarker level (e.g., expression level or phosphorylation level) in one or more (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, or 40 or more) human subjects that have not responded to treatment with a CDK2 inhibitor. This pre-established reference value (which may be an average or median level (e.g., gene copy number, expression level, or phosphorylation level) taken from multiple human subjects that have not responded to the therapy) may then be used for the “control” level of the biomarker (e.g., CCNE1, p16, or Rb phosphorylation) in the comparison with the test sample. In such a comparison, the human subject is predicted to respond to a CDK2 inhibitor if the CCNE1 gene is amplified and/or the expression level of CCNE is higher than the pre- established reference, and a CDKN2A gene encoding a p16 protein comprising the amino acid sequence of SEQ ID NO:1 is present, a CDKN2A gene lacking one or more inactivating nucleic acid substitutions and/or deletions is present, and/or a p16 protein (e.g., a p16 protein comprising the amino acid sequence of SEQ ID NO:1) is present. In another such a comparison, the human subject is predicted to respond to a CDK2 inhibitor if (i) CCNE1 gene is amplified and/or the expression level of CCNE is higher than the pre-established reference, and (ii) after administering to the human subject a CDK2 inhibitor, the level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3 is lower than the pre-established reference. In yet another such a comparison, the human subject is indicated to respond to a CDK2 inhibitor if (i) CCNE1 gene is amplified and/or the expression level of CCNE is higher than the pre-established reference, (ii) a CDKN2A gene encoding a p16 protein comprising the amino acid sequence of SEQ ID NO:1 is present, a CDKN2A gene lacking one or more inactivating nucleic acid substitutions and/or deletions is present, and/or a p16 protein (e.g., a p16 protein comprising the amino acid sequence of SEQ ID NO:1) is present, and (iii) after administering to the human subject a CDK2 inhibitor, the level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3 is lower than the pre- established reference. The “control” level for a particular biomarker in a particular cell type or tissue may alternatively be pre-established by an analysis of biomarker level in one or more human subjects that have responded to treatment with a CDK2 inhibitor. This pre- established reference value (which may be an average or median level (e.g., expression level or phosphorylation level) taken from multiple human subjects that have responded to the therapy) may then be used as the “control” level (e.g., expression level or phosphorylation level) in the comparison with the test sample. In such a comparison, the human subject is indicated to respond to a CDK2 inhibitor if the level (e.g., copy number of the CCNE1 gene, expression level of CCNE1, expression level of p16, or phosphorylation level of Rb at the serine corresponding to amino acid position 780 of SEQ ID NO:3) of the biomarker being analyzed is equal or comparable to (e.g., at least 85% but less than 115% of), the pre-established reference. In certain embodiments, the “control” is a pre-established cut-off value. A cut-off value is typically a level (e.g., a copy number, an expression level, or a phosphorylation level) of a biomarker above or below which is considered predictive of responsiveness of a human subject to a therapy of interest. Thus, in accordance with the methods and compositions described herein, a reference level (e.g., of CCNE1 gene copy number, CCNE1 expression, p16 expression, or Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3) is identified as a cut-off value, above or below of which is predictive of responsiveness to a CDK2 inhibitor. Cut-off values determined for use in the methods described herein can be compared with, e.g., published ranges of concentrations but can be individualized to the methodology used and patient population. In some embodiments, the expression level of CCNE1 is increased as compared to the expression level of CCNE1 in a control. For example, the expression level of CCNE1 analyzed can be at least 1.5, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 20, at least 25, at least 50, at least 75, or at least 100 times higher, or at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 100%, at least 200%, at least 300%, at least 400%, at least 500%, at least 600%, at least 700%, at least 800%, at least 900%, at least 1,000%, at least 1,500%, at least 2,000%, at least 2,500%, at least 3,000%, at least 3,500%, at least 4,000%, at least 4,500%, or at least 5,000% higher, than the expression level of CCNE1 in a control. A p16 protein is present if the protein is detectable by any assay known in the art or described herein, such as, for example, western blot, immunohistochemistry, fluorescence-activated cell sorting, and enzyme-linked immunoassay. In some embodiments, a p16 protein is present at an expression level that is within at least 5%, at least 10%, at least 20%, or at least 30% of the p16 expression level in a healthy control. In some embodiments, the level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3 being analyzed is reduced as compared to the level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3 in a control. For example, the level of the Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3 being analyzed can be at least 1.5, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 20, at least 25, at least 50, at least 75, or at least100 times lower, or at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, or 100% lower, than the level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3 in a control. Biological Samples Suitable biological samples for the methods described herein include any sample that contains blood or tumor cells obtained or derived from the human subject in need of treatment. For example, a biological sample can contain tumor cells from biopsy from a patient suffering from a solid tumor. A tumor biopsy can be obtained by a variety of means known in the art. Alternatively, a blood sample can be obtained from a patients suffering from a hematological cancer. A biological sample can be obtained from a human subject having, suspected of having, or at risk of developing, a disease or disorder associated with CDK2. In some embodiments, the disease or disorder associated with CDK2 is a cancer (such as those described supra). Methods for obtaining and/or storing samples that preserve the activity or integrity of molecules (e.g., nucleic acids or proteins) in the sample are well known to those skilled in the art. For example, a biological sample can be further contacted with one or more additional agents such as buffers and/or inhibitors, including one or more of nuclease, protease, and phosphatase inhibitors, which preserve or minimize changes in the molecules in the sample. Evaluating Biomarkers and Pharmacodynamic Markers Expression levels of CCNE1 or p16 can be detected as, e.g., RNA expression of a target gene (i.e., the genes encoding CCNE1 or p16). That is, the expression level (amount) of CCNE1 or p16 can be determined by detecting and/or measuring the level of mRNA expression of the gene encoding CCNE1. Alternatively, expression levels of CCNE1 or p16 can be detected as, e.g., protein expression of target gene (i.e., the genes encoding CCNE1 or p16). That is, the expression level (amount) of CCNE1 or p16 can be determined by detecting and/or measuring the level of protein expression of the genes encoding CCNE1 or p16. In some embodiments, the expression level of CCNE1 or p16 is determined by measuring RNA levels. A variety of suitable methods can be employed to detect and/or measure the level of mRNA expression of a gene. For example, mRNA expression can be determined using Northern blot or dot blot analysis, reverse transcriptase-PCR (RT-PCR; e.g., quantitative RT-PCR), in situ hybridization (e.g., quantitative in situ hybridization), nucleic acid array (e.g., oligonucleotide arrays or gene chips) and RNA sequencing analysis. Details of such methods are described below and in, e.g., Sambrook et al., Molecular Cloning: A Laboratory Manual Second Edition vol.1, 2 and 3. Cold Spring Harbor Laboratory Press: Cold Spring Harbor, New York, USA, Nov.1989; Gibson et al. (1999) Genome Res., 6(10):995-1001; and Zhang et al. (2005) Environ. Sci. Technol., 39(8):2777-2785; U.S. Publication No. 2004086915; European Patent No.0543942; and U.S. Patent No.7,101,663; Kukurba et al. (2015) Cold Spring Harbor Protocols., 2015 (11): 951–69; the disclosures of each of which are incorporated herein by reference in their entirety. In one example, the presence or amount of one or more discrete mRNA populations in a biological sample can be determined by isolating total mRNA from the biological sample (see, e.g., Sambrook et al. (supra) and U.S. Patent No. 6,812,341) and subjecting the isolated mRNA to agarose gel electrophoresis to separate the mRNA by size. The size-separated mRNAs are then transferred (e.g., by diffusion) to a solid support such as a nitrocellulose membrane. The presence or amount of one or more mRNA populations in the biological sample can then be determined using one or more detectably-labeled-polynucleotide probes, complementary to the mRNA sequence of interest, which bind to and thus render detectable their corresponding mRNA populations. Detectable-labels include, e.g., fluorescent (e.g., umbelliferone, fluorescein, fluorescein isothiocyanate, rhodamine, dichlorotriazinylamine fluorescein, dansyl chloride, allophycocyanin, or phycoerythrin), luminescent (e.g., europium, terbium, Qdot™ nanoparticles supplied by the Quantum Dot Corporation, Palo Alto, CA), radiological (e.g., 125I, 131I, 35S, 32P, 33P, or 3H), and enzymatic (horseradish peroxidase, alkaline phosphatase, beta- galactosidase, or acetylcholinesterase) labels. In some embodiments, the expression level of CCNE1 or p16 is determined by measuring protein levels. A variety of suitable methods can be employed to detect and/or measure the level of protein expression of target genes. For example, CCNE1 or p16 protein expression can be determined using western blot, enzyme-linked immunosorbent assay (“ELISA”), fluorescence activated cell sorting, or immunohistochemistry analysis (e.g., using a CCNE1-specific or p16-specific antibody, respectively). Details of such methods are described below and in, e.g., Sambrook et al., supra. In one example, the presence or amount of one or more discrete protein populations (e.g., CCNE1 or p16) in a biological sample can be determined by western blot analysis, e.g., by isolating total protein from the biological sample (see, e.g., Sambrook et al. (supra)) and subjecting the isolated protein to agarose gel electrophoresis to separate the protein by size. The size-separated proteins are then transferred (e.g., by diffusion) to a solid support such as a nitrocellulose membrane. The presence or amount of one or more protein populations in the biological sample can then be determined using one or more antibody probes, e.g., a first antibody specific for the protein of interest (e.g., CCNE1 or p16), and a second antibody, detectably labeled, specific for the first antibody, which binds to and thus renders detectable the corresponding protein population. Detectable-labels suitable for use in western blot analysis are known in the art. Methods for detecting or measuring gene expression (e.g., mRNA or protein expression) can optionally be performed in formats that allow for rapid preparation, processing, and analysis of multiple samples. This can be, for example, in multi- welled assay plates (e.g., 96 wells or 386 wells) or arrays (e.g., nucleic acid chips or protein chips). Stock solutions for various reagents can be provided manually or robotically, and subsequent sample preparation (e.g., RT-PCR, labeling, or cell fixation), pipetting, diluting, mixing, distribution, washing, incubating (e.g., hybridization), sample readout, data collection (optical data) and/or analysis (computer aided image analysis) can be done robotically using commercially available analysis software, robotics, and detection instrumentation capable of detecting the signal generated from the assay. Examples of such detectors include, but are not limited to, spectrophotometers, luminometers, fluorimeters, and devices that measure radioisotope decay. Exemplary high-throughput cell-based assays (e.g., detecting the presence or level of a target protein in a cell) can utilize ArrayScan® VTI HCS Reader or KineticScan® HCS Reader technology (Cellomics Inc., Pittsburg, PA). In some embodiments, the presence of a CDKN2A gene encoding a p16 protein comprising the amino acid sequence of SEQ ID NO:1 and/or the presence of a CDKN2A gene lacking one or more inactivating nucleic acid substitutions and/or deletions is determined by evaluating the DNA sequence of the CDKN2A gene (e.g., genomic DNA or cDNA) or by evaluating the RNA sequence of the CDKN2A gene (e.g., RNA, e.g., mRNA). Methods of performing nucleic acid sequencing analyses are known in the art and described above. Nonlimiting examples of inactivating nucleic acid substitutions and/or deletions preventing the CDKN2A gene from encoding a protein comprising the amino acid sequence of SEQ ID NO:1 are described in Table A, above. In specific embodiments, the one or more inactivating nucleic acid substitutions and/or deletions in the CDKN2A gene is as described in Yarbrough et al., Journal of the National Cancer Institute, 91(18):1569-1574, 1999; Liggett and Sidransky, Biology of Neoplasia, Journal of Oncology, 16(3):1197-1206, 1998, and Cairns et al., Nature Genetics, 11:210-212, 1995, each of which is incorporated by reference herein in its entirety. In some embodiments, the expression level of a gene or the presence of a gene lacking one or more inactivating nucleic acid substitutions or deletions is determined by evaluating the copy number variation (CNV) of the gene. The CNV of genes (e.g., the CCNE1 gene and/or the CDKN2A gene) can be determined/identified by a variety of suitable methods. For example, CNV can be determined using fluorescent in situ hybridization (FISH), multiplex ligation dependent probe amplification (MLPA), array comparative genomic hybridization (aCGH), single-nucleotide polymorphisms (SNP) array, and next-generation sequencing (NGS) technologies. In one example, the copy number variation of one or more discrete genes in a biological sample can be determined by MLPA, e.g., by extracting DNA specimens from the biological sample (see, e.g., Sambrook et al. (supra) and U.S. Patent No. 6,812,341), and amplifying DNA sequence of interest (e.g., CCNE1 or CDKN2A) using a mixture of MLPA probes. Each MLPA probe consists of two oligonucleotides that hybridize to immediately adjacent target DNA sequence (e.g., CCNE1 or CDKN2A) in order to be ligated into a single probe. Ligated probes are amplified though PCR with one PCR primer fluorescently labeled, enabling the amplification products to be visualized during fragment separation by capillary electrophoresis. The presence, absence or amplification of one or more genes of interest in the biological sample is calculated by measuring PCR derived fluorescence, quantifying the amount of PCR product after normalization and comparing it with control DNA samples. The level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3 can be detected by a variety of suitable methods. For example, phosphorylation status can be determined using western blot, ELISA, fluorescence activated cell sorting, or immunohistochemistry analysis. Details of such methods are described below and in, e.g., Sambrook et al., supra. As with the methods for detecting or measuring gene expression (above), methods for detecting or measuring the level of Rb phosphorylation at the serine corresponding to amino acid position 780 of SEQ ID NO:3 can optionally be performed in formats that allow for rapid preparation, processing, and analysis of multiple samples. The invention will be described in greater detail by way of specific examples. The following examples are offered for illustrative purposes, and are not intended to limit the invention in any manner. Those of skill in the art will readily recognize a variety of non-critical parameters which can be changed or modified to yield essentially the same results.
