[0002] Field of the Disclosure The present application relates to the treatment of prostate cancer, including metastatic and / or castration-resistant prostate cancer, comprising administering to a subject in need thereof a compound of formula (I). [Background technology]

[0003] Background of the Disclosure The androgen receptor (AR) belongs to the nuclear hormone receptor family, which is activated by androgens such as testosterone and dihydrotestosterone (Pharmacol. Rev. 2006, 58(4), 782-97 (Non-Patent Document 1); Vitam. Horm. 1999, 55:309-52 (Non-Patent Document 2)). In the absence of androgens, the AR is bound to heat shock protein 90 (Hsp90) in the cytosol. When androgens bind to the AR, its conformational change causes the AR to be released from Hsp90, exposing a nuclear localization signal (NLS). This allows the AR to translocate into the nucleus, where it acts as a transcription factor to promote the expression of genes involved in male sexual characteristics (Endocr. Rev. 1987, 8(1):1-28 (Non-Patent Document 3); Mol. Endocrinol. 2002, 16(10), 2181-7 (Non-Patent Document 4)). AR deficiency leads to androgen insensitivity syndrome, formerly known as testicular feminization syndrome.

[0004] AR is involved in the development of male sexual characteristics, but it has also been well documented to be an oncogene in certain forms of cancer, including prostate cancer (Endocr. Rev. 2004, 25(2), 276-308 (Non-Patent Document 5)). A commonly measured target gene of AR activity is the secreted prostate-specific antigen (PSA) protein. Current treatment regimens for prostate cancer include inhibiting the androgen-AR axis by two methods. The first method relies on androgen reduction, while the second method aims to inhibit AR function (Nat. Rev. Drug Discovery, 2013, 12, 823-824 (Non-Patent Document 6)). Despite the development of effective targeted therapies, many patients develop resistance and the disease progresses. An alternative approach to prostate cancer treatment involves ablation of the AR protein. Because AR is a key inducer of tumorigenesis in many types of prostate cancer, its elimination should produce a therapeutically beneficial response. There is a continuing need in the art for effective treatments for diseases, particularly cancer, prostate cancer, and Kennedy's disease. However, transcription factors, for example, have non-specific effects and are unable to completely target and regulate specific classes of proteins. This remains an obstacle to the development of effective anti-cancer drugs. Therefore, a "tunable" small molecule therapeutic agent that activates or enhances the substrate specificity of cereblon and simultaneously targets and specifically regulates a wide range of protein species would be very useful as a therapeutic agent.

DETAILED DESCRIPTION OF THE INVENTION

[0046] Detailed Description definition "Halogen" or "halo" refers to fluorine (F), chlorine (Cl), bromine (Br) or iodine (I).

[0047] "C1-C6 alkyl" refers to a straight or branched chain saturated hydrocarbon containing from 1 to 6 carbon atoms. Examples of (C1-C6) alkyl groups include, but are not limited to, methyl, ethyl, propyl, butyl, pentyl, hexyl, isopropyl, isobutyl, sec-butyl, tert-butyl, isopentyl, neopentyl, and isohexyl.

[0048] As used herein with respect to compounds of Formula (I), "pharmaceutically acceptable salts" refers to salt forms and hydrates of salt forms in which one or more water molecules are present of compounds of Formula (I). Such salts and hydrate forms retain the biological activity of compounds of Formula (I) and are not biologically or otherwise undesirable, i.e., exhibit minimal, if any, toxicological effects. Representative "pharmaceutically acceptable salts" include, for example, acetate, anthonate (4,4-diaminostilbene-2,2-disulfonate), benzenesulfonate, benzoate, bicarbonate, bisulfate, bitartrate, borate, bromide, butyrate, calcium, calcium edetate, camsylate, carbonate, chloride, citrate, clavulariate, dihydrochloride, edetate, edisylate, estolate, esylate, fumarate, gluceptate, gluconate, glutamate, glycolyl arsanilate, hexafluorophosphate, hexylresorcinate, hydrabamine, hydrobromide, hydrochloride, hydroxynaphthoate, iodide, isothionate, lactate, lactobionate, laurate. , magnesium, malate, maleate, mandelate, mesylate, methyl bromide, methyl nitrate, methyl sulfate, mucate, napsylate, nitrate, N-methylglucamine ammonium salt, 3-hydroxy-2-naphthoate, oleate, oxalate, palmitate, pamoate (1,1-methane-bis-2-hydroxy-3-naphthoate, eimbonate), pantothenate, phosphate / diphosphate, picrate, polygalacturonate, propionate, p-toluenesulfonate, salicylate, stearate, subacetate, succinate, sulfate, sulfosalicylate, suramate, tannate, tartrate, teoclate, tosylate, triethiodide, and valerate salts.

[0049] The term "isomer" refers to salts and / or compounds that have the same composition and molecular weight but differ in physical and / or chemical properties. The structural differences can be in constitution (geometric isomers) or in the ability to rotate the plane of polarized light (stereoisomers). With respect to stereoisomers, salts of compounds of formula (I) may have one or more asymmetric carbon atoms and may occur as racemates, racemic mixtures, and as individual enantiomers or diastereomers.

[0050] Compounds of formula (I) may exist in unsolvated as well as solvated forms, such as, for example, hydrated forms.

[0051] "Solvate" refers to a solvent addition form containing either a stoichiometric or non-stoichiometric amount of solvent. Some compounds tend to trap a fixed molar ratio of solvent molecules in the crystalline solid state, thus forming a solvate. When the solvent is water, the solvate formed is a hydrate, and when the solvent is alcohol, the solvate formed is an alcoholate. Hydrates are formed by the combination of one or more water molecules with one of the substances in which water retains its molecular state as HO, and such combinations can form one or more hydrates. In hydrates, water molecules are bonded through subvalent bonds by intermolecular forces, particularly hydrogen bridges. Solid hydrates contain water in a stoichiometric ratio as so-called water of crystallization, and the water molecules do not necessarily have to be equivalent in terms of their bonding state. Examples of hydrates include sesquihydrates, monohydrates, dihydrates, or trihydrates. Similarly, hydrates of salts of the compounds of the present invention are also suitable.

[0052] When a compound is crystallized from a solution or slurry, it may crystallize in different lattice arrangements in space (this property is called polymorphism), forming crystals with different crystalline forms, each of which is known as a "polymorph." As used herein, "polymorph" refers to a crystalline form of a compound of formula (I) in which the molecules are localized in three-dimensional lattice sites. Different polymorphs of a compound of formula (I) may differ from each other in one or more physical properties, such as solubility and dissolution rate, true specific gravity, crystalline form, storage mode, flowability, and / or solid-state stability.

[0053] As referred to herein, an "isotopic derivative" refers to a compound of formula (I) that is isotopically enriched or labeled (with respect to one or more atoms of the compound) with one or more stable isotopes. Thus, in this application, a compound of formula (I) includes compounds that are isotopically enriched or labeled with one or more atoms, such as, for example, deuterium.

[0054] The term "pharmaceutically acceptable prodrug," as used herein, refers to a prodrug of a compound of Formula (I) that is, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals with excessive toxicity, irritation, allergic response, etc., commensurate with a reasonable benefit / risk ratio, and is effective for its intended use, and where possible, is the zwitterionic form of the compound of this invention.

[0055] As used herein, "prodrug" means a compound that is convertible in vivo by metabolic means (e.g., by hydrolysis) to yield any compound detailed by the formulae of the invention. Various forms of prodrugs are known in the art, and are described, for example, in Bundgaard, (ed.), Design of Prodrugs, Elsevier (1985); Widder et al. (ed.), Methods in Enzymology, vol. 4, Academic Press (1985); Krogsgaard-Larsen et al. (ed.), "Design and Application of Prodrugs, Textbook of Drug Design and Development," Chapter 5, 113-191 (1991); Bundgaard et al., Journal of Drug Deliver Reviews, 8:1-38 (1992); Bundgaard, J. of Pharmaceutical Sciences, 77:285 et seq. (1988); Higuchi and Stella (eds.) Prodrugs as Novel Drug Delivery Systems, American Chemical Society (1975) and Bernard Testa & Joachim Mayer, "Hydrolysis In Drug and Prodrug This is discussed in "Metabolism: Chemistry, Biochemistry And Enzymology" John Wiley and Sons, Ltd. (2002).

[0056] The present invention also encompasses pharmaceutical compositions containing pharmaceutically acceptable prodrugs of the compounds of the present invention, and methods for treating disorders by administering pharmaceutically acceptable prodrugs of the compounds of the present invention. For example, compounds of the present invention having free amino, amide, hydroxy, or carboxylic acid groups can be converted into prodrugs. Prodrugs include compounds in which an amino acid residue, or a polypeptide chain of two or more (e.g., two, three, or four) amino acid residues, is covalently linked to a free amino, hydroxy, or carboxylic acid group of a compound of the present invention via an amide or ester bond.

[0159] The therapeutically effective amount of a compound of formula (I) can be initially estimated either in cell culture assays or animal models, usually rats, mice, rabbits, dogs, or pigs. Animal models can also be used to determine appropriate concentration ranges and administration routes. Such information can then be used to determine useful doses and routes for administration in humans. Therapeutic / prophylactic efficacy and toxicity can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, for example, ED 50 (therapeutic effective dose in 50% of the population) and LD 50 (the lethal dose for 50% of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index, and the LD 50 / ED 50It can be expressed as a ratio. Pharmaceutical compositions that exhibit large therapeutic indices are preferred. The dosage can vary within this range depending on the dosage form employed, sensitivity of the patient, and the route of administration.

[0160] Dosage and administration are adjusted to provide sufficient levels of the compound of Formula (I) or to maintain the desired effect. Factors that may be considered include the severity of the condition, the subject's general health, the subject's age, weight, and sex, diet, time and frequency of administration, drug combinations, reaction sensitivities, and tolerance / response to therapy. Long-acting pharmaceutical compositions may be administered every 3-4 days, every week, or every two weeks, depending on the half-life and clearance rate of the particular formulation.

In one embodiment, the abiraterone is abiraterone acetate.

[0163] In one embodiment, for a method of treating prostate cancer with a combination of a compound of Formula (I) and abiraterone acetate, a therapeutically effective amount of the compound of Formula (I) is described herein, and the therapeutically effective amount of abiraterone acetate is 1,000 mg orally administered once daily for 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 30, or more consecutive days, in single or divided doses. In one embodiment, abiraterone acetate is orally administered twice daily in combination with 5 mg of prednisone. In one embodiment, the combination of a compound of Formula (I) and abiraterone acetate is administered to a subject in need thereof in a fasted state. In one embodiment, the subject has not eaten for at least 2 hours before and at least 1 hour after administration of the combination of a compound of Formula (I) and abiraterone acetate.

[0164] In one embodiment, the compound of formula (I) and abiraterone acetate are administered to the subject simultaneously. In one embodiment, the compound of formula (I) and abiraterone acetate are administered to the subject sequentially.

[0165] In one embodiment, the compound of formula (I) and abiraterone acetate are administered closely in time to a subject.

[0166] In some embodiments, "temporal proximity" refers to administering the compound of Formula (I) within a period of time before or after administration of abiraterone acetate, such that the therapeutic effect of the compound of Formula (I) overlaps with the therapeutic effect of abiraterone acetate. In some embodiments, the therapeutic effect of the compound of Formula (I) completely overlaps with the therapeutic effect of abiraterone acetate. In some embodiments, "temporal proximity" refers to administering the compound of Formula (I) within a period of time before or after administration of abiraterone acetate, such that the compound of Formula (I) and abiraterone acetate have a synergistic effect.

[0167] "Temporal proximity" can vary depending on various factors, including, but not limited to, the age, sex, weight, genetic background, health status, medical history, and treatment history of the subject receiving the therapeutic agent; the disease or condition being treated or alleviated; the therapeutic outcome being achieved; the dose, frequency, and duration of administration of the therapeutic agent; the pharmacokinetics and pharmacodynamics of the therapeutic agent; and the route by which the therapeutic agent is administered. In some embodiments, "temporal proximity" means within 15 minutes, 30 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 8 hours, 12 hours, 18 hours, 24 hours, 36 hours, 2 days, 3 days, 4 days, 5 days, 6 days, 1 week, 2 weeks, 3 weeks, 4 weeks, 6 weeks, or 8 weeks. In some embodiments, multiple administrations of one therapeutic agent can be administered in close temporal proximity to a single administration of another therapeutic agent. In some embodiments, temporal proximity can vary during a treatment cycle or within a dosing regimen.

[0168] Pharmaceutical Composition In one embodiment, the compound of formula (I) is formulated for oral administration. For example, in one embodiment, the compound of formula (I) is formulated as a tablet containing 0, 1, 2 or more of an emulsifier, a surfactant, a binder, a disintegrant, a glidant and a lubricant.

[0169] In one embodiment, the emulsifier is hypromellose.

[0170] In one embodiment, the surfactant is vitamin E polyethylene glycol succinate.

[0171] In one embodiment, the binder (also referred to herein as a filler) is selected from the group consisting of microcrystalline cellulose, lactose monohydrate, sucrose, glucose, and sorbitol.

[0172] In one embodiment, the disintegrant is croscarmellose sodium.

[0173] In one embodiment, a lubricant refers to a substance used to promote powder flow by reducing interparticle cohesion. In one embodiment, in the dosage form of the present disclosure, the lubricant is selected from the group consisting of silicon dioxide, colloidal anhydrous silica, starch, and talc.

[0174] In one embodiment, a lubricant refers to a substance that prevents ingredients from sticking and / or clumping in machinery used to prepare the dosage forms of the present disclosure. In one embodiment, in the dosage forms of the present disclosure, the lubricant is selected from the group consisting of magnesium stearate, sodium stearyl fumarate, stearic acid, and vegetable stearin.

[0175] Pharmaceutical compositions containing compounds of formula (I) can be prepared in a generally known manner, for example, by conventional mixing, dissolving, granulating, dragee-making, pulverizing, emulsifying, encapsulating, encapsulating or lyophilizing processes. Pharmaceutical compositions can be formulated in a conventional manner using one or more pharmaceutically acceptable carriers, including excipients and / or adjuvants, that facilitate the processing of the compounds of formula (I) into pharmaceutically usable preparations. Of course, the appropriate formulation depends on the selected route of administration.

[0176] Pharmaceutical compositions suitable for injection include sterile aqueous solutions (where water soluble) or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. For intravenous administration, suitable carriers include physiological saline, bacteriostatic water, Cremophor EL™ (BASF, Parsippany, NJ), or phosphate-buffered saline (PBS). In all cases, the composition must be sterile and fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol, and liquid polyethylene glycol), and suitable mixtures thereof. Proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants. Prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as mannitol or sorbitol, or sodium chloride in the composition. Prolonged absorption of the injectable compositions can be brought about by including in the composition an agent which delays absorption, for example, aluminum monostearate and gelatin.

[0177] Sterile injectable solution can be prepared by incorporating the compound of formula (I) in the required amount in a suitable solvent with one or a combination of the above-listed components, and then optionally sterilizing by filtration.Generally, dispersion is prepared by incorporating active agent or compound into a sterile vehicle that contains a basic dispersion medium and other components required from the above-listed components.For the preparation of sterile powder for sterile injectable solution, the preparation method is vacuum drying and freeze-drying, which produces a powder of active ingredient and any additional desired components from the solution that has been previously sterilized and filtered.

[0178] Oral compositions generally contain an inert diluent or an edible pharmaceutically acceptable carrier. They may be encapsulated in gelatin capsules or compressed into tablets. For oral therapeutic administration, the compound of formula (I) can be combined with an excipient and used in the form of tablets, lozenges or capsules. Oral compositions can also be prepared using a fluid carrier for use as a mouthwash, where the drug or compound in the fluid carrier is orally applied, swished, expectorated, or swallowed. Pharmaceutically compatible binding agents and / or adjuvants can be included as part of the composition. Tablets, pills, capsules, troches, etc. may contain any of the following ingredients: a binder such as microcrystalline cellulose, gum tragacanth, or gelatin; an excipient such as starch or lactose; a dispersing agent such as alginic acid, sodium starch glycolate (Primogel®), or corn starch; a lubricant such as magnesium stearate; a glidant such as colloidal silicon dioxide; a sweetener such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate, or orange flavoring, or compounds of a similar nature.

[0179] For administration by inhalation, the agents or compounds are delivered in the form of an aerosol spray from pressured container or dispenser which contains a suitable propellant, eg, a gas such as carbon dioxide, or a nebulizer.

[0180] Systemic administration can also be via transmucosal or transdermal means.For transmucosal or transdermal administration, a penetrant suitable for the barrier to be permeated is used in the formulation.Such penetrants are generally known in the art, and for example, for transmucosal administration, include detergents, bile salts, and fusidic acid derivatives.Transmucosal administration can be achieved by using nasal sprays or suppositories.For transdermal administration, the active agent or compound is formulated into ointments, salves, gels, or creams generally known in the art.

[0181] In one aspect, the compound of formula (I) is prepared with pharmaceutically acceptable carrier, for example, release-controlled preparations, including implants and microencapsulated delivery systems, to protect drug or compound from rapid excretion from body.For example, biodegradable and biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydride, polyglycolic acid, collagen, polyorthoester and polylactic acid.The method of preparing such preparations will be clear to those skilled in the art.

[0182] Liposomal suspensions (including liposomes targeted to infected cells with monoclonal antibodies against viral antigens) can also be used as pharmaceutically acceptable carriers. These can be prepared according to methods known to those skilled in the art, for example, as described in U.S. Patent No. 4,522,811.

[0183] For ease of administration and uniformity of dosage, it is particularly advantageous to formulate oral or parenteral compositions into unit dosage form.As used herein, unit dosage form refers to a physically separate unit that is suitable as a unit dose for the subject to be treated, and each unit contains a predetermined amount of active agent or compound that is calculated to produce desired therapeutic effect in association with given pharmaceutical carrier.The specification of unit dosage form in this application is determined by and directly depends on the inherent properties of the compound of formula (I) and the specific therapeutic effect that is achieved.

[0184] The pharmaceutical compositions can be included in a container, pack, or dispenser together with instructions for administration.

[0185] Exemplary administration modes of the compound of Formula (I) include systemic administration or local administration, such as oral, nasal, parenteral, transdermal, subcutaneous, vaginal, buccal, rectal, or topical administration modes. In one embodiment, the compound of Formula (I), or a pharmaceutically acceptable salt or hydrate thereof, is administered orally. In one embodiment, the compound of Formula (I) is administered as a tablet, capsule, caplet, solution, suspension, syrup, granules, beads, powder, or pellet.

[0186] Exemplary pharmaceutical compositions are tablets and gelatin capsules comprising a salt of a compound of formula (I) and a pharmaceutically acceptable carrier, such as a) a diluent, for example, purified water, triglyceride oils such as hydrogenated or partially hydrogenated vegetable oils or mixtures thereof, such as corn oil, olive oil, sunflower oil, safflower oil, fish oils such as EPA and DHA or their esters or triglycerides or mixtures thereof, omega-3 fatty acids or derivatives thereof, lactose, dextrose, sucrose, mannitol, sorbitol, cellulose, sodium, saccharin, glucose and / or glycine; b) a lubricant, for example, silica, talcum, stearic acid, magnesium or calcium salts, sodium oleate, sodium stearate, stearic acid ...stearate, stearic acid, sodium oleate, sodium stearate, stearic acid, sodium stearate, stearic acid, sodium oleate also for tablets, c) binders, for example magnesium aluminum silicate, starch paste, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, magnesium carbonate, natural sugars such as glucose or beta-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth or sodium alginate, waxes and / or polyvinylpyrrolidone, optionally d) disintegrating agents, for example starch, agar, methylcellulose, bentonite, xanthan gum, alginic acid or its sodium salt, or effervescent mixtures, e) absorbents, colorants, flavors and sweeteners, f) emulsifiers or dispersing agents, for example Tween 80, Labrasol, HPMC, DOSS, Caproil 909, Labrac, Labrafil, Peseol, Transcatol, capmul MCM, capmul PG-12, Captex 355, Gelucire, Vitamin E TGPS or other acceptable emulsifier, and / or g) an agent that enhances salt absorption such as cyclodextrin, hydroxypropyl-cyclodextrin, PEG400, and / or PEG200.

[0187] For preparing pharmaceutical compositions from a compound of Formula (I) or any salt or hydrate thereof, inert, pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, dispersible granules, capsules, cachets, and suppositories. Powders and tablets may contain from about 5 to about 95% of the active ingredient. Suitable solid carriers are known in the art and include, for example, magnesium carbonate, magnesium stearate, talc, sugar, or lactose. Tablets, powders, cachets, and capsules can be used as solid dosage forms suitable for oral administration. Examples of pharmaceutically acceptable carriers and manufacturing methods for various compositions can be found in A. Gennaro (ed.), Remington's Pharmaceutical Sciences, 18th Edition, (1990), Mack Publishing Co., Easton, Pa.

[0188] Liquid form preparations include solutions, suspensions and emulsions. For example, water or water-propylene glycol solutions for parenteral injection, or the addition of sweeteners and opacifiers for oral solutions, suspensions and emulsions. Liquid form preparations may also include solutions for intranasal administration.

[0189] Liquid compositions, particularly for injection, can be prepared, for example, by dissolving, dispersing, etc. For example, the disclosed salts are dissolved in or mixed with a pharmaceutically acceptable solvent, such as, for example, water, saline, aqueous dextrose, glycerol, ethanol, etc., to thereby form an injectable isotonic solution or suspension. Proteins such as albumin, chylomicron particles, or serum proteins can be used to solubilize the disclosed compounds.

[0190] Parenteral injectable administration is commonly used for subcutaneous, intramuscular, or intravenous injections and infusions. Injectables can be prepared in conventional forms, either as liquid solutions or suspensions, or in solid form suitable for dissolution in liquid prior to injection.

[0191] Aerosol preparations suitable for inhalation may include solutions and solids in powder form, which may be in combination with a pharmaceutically acceptable carrier, such as an inert compressed gas, e.g., nitrogen.

[0192] Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for either oral or parenteral administration. Such liquid forms include solutions, suspensions, and emulsions.

[0193] Depending on the intended method of administration, the disclosed compositions may be in solid, semi-solid, or liquid dosage forms, such as, for example, injectables, tablets, suppositories, pills, sustained-release capsules, elixirs, tinctures, emulsions, syrups, powders, liquids, suspensions, etc., sometimes even in unit doses, consistent with conventional pharmaceutical practice. Similarly, they may also be administered in intravenous (both bolus and infusion), intraperitoneal, subcutaneous, or intramuscular form, all of which can be administered using forms well known to those skilled in the art of pharmaceuticals.

[0194] The pharmaceutical compositions can be prepared according to conventional mixing, granulating, or coating methods, respectively, and can contain about 0.1% to about 99%, about 5% to about 90%, or about 1% to about 20% by weight or volume of a salt of the present disclosure.

[0195] All amounts of any component of the oral dosage forms, e.g., tablets, described herein, given on a % w / w basis refer to the total weight of the oral dosage form, unless otherwise indicated. [Example]

[0196] The present disclosure is further illustrated by the following examples, which should not be construed as limiting the scope or spirit of the present disclosure to the specific procedures described herein. Of course, the examples are provided to illustrate certain embodiments, and no limitation on the scope of the present disclosure is intended thereby. It should be further understood that various other embodiments, modifications, and equivalents thereof may be made without departing from the spirit of the present disclosure and / or the scope of the appended claims, which may suggest themselves to those skilled in the art.

[0197] Example 1 - In vitro studies with compound (IG) Compound (Ig) was shown to degrade 95% to 98% of androgen receptors (AR) in multiple cell lines typically used in prostate cancer research, including VCaP cells. 50 (The concentration of compound Ig is 1 nM.) Near-maximal degradation was observed within 4 hours of administration of compound Ig. Compound Ig inhibited VCaP proliferation approximately 60-fold more potently than enzalutamide (Figure 1).

[0198] FIG. 2 shows the reduction of AR in VCaP tumor cells in response to treatment with Compound (Ig) at concentrations of 0.03 nM, 0.1 nM, 0.3 nM, 1 nM, 3 nM, 10 nM, 30 nM, 100 nM and 300 nM.

[0199] Example 2 - In vivo animal testing and evaluation of preclinical efficacy exposure range for Compound (Ig) Preclinical animal studies were conducted with compound (Ig) in a VCaP xenograft animal model. VCaP was derived from metastatic growths of prostate cancer in the spine. This cell line is desirable for in vivo testing because it exhibits many of the characteristics of clinical prostate cancer. VCaP also expresses AR splice variants, which have been shown to promote resistance to AR antagonists, making it a useful model for studying AR resistance.

[0200] Once-daily oral administration of Compound (Ig) at doses of 0.1 mg / kg (mpk), 0.3 mg / kg, 1 mg / kg, and 3 mg / kg was performed in a castrated VCaP xenograft model (Figure 3). Enzalutamide (20 mg / kg) and vehicle were also used as controls.

[0201] Once-daily oral administration of Compound (Ig) at doses of 1 mg / kg, 3 mg / kg, and 10 mg / kg was performed in intact (non-castrated) VCaP xenograft models (Figure 4). Enzalutamide (20 mg / kg) and vehicle were also used as controls.

[0202] Once-daily oral administration of Compound (Ig) at doses of 3 mg / kg and 10 mg / kg was performed in an enzalutamide-resistant VCaP xenograft model (Figure 5). Enzalutamide (20 mg / kg) and vehicle were also used as controls.

[0203] The pharmacokinetic results of once-daily oral administration of Compound (Ig) at doses of 1 mg / kg and 3 mg / kg are shown in Table 1 below. The 1 mg / kg dose of Compound (Ig) was the lowest dose superior to enzalutamide in VCaP xenografts. The 3 mg / kg dose of Compound (Ig) was the minimally effective dose in the enzalutamide-resistant VCaP model (70% tumor growth inhibition compared to the control group).

[0204] FIG. 6 shows the reduction of AR in enzalutamide-resistant VCaP tumors in response to Compound (Ig) administration (oral, once daily) at 10 mg / kg and 3 mg / kg.

[0205] [Table 1] Values ​​represent total drug concentrations. † AUC, or area under the curve, is a measure of total exposure. ‡ C maxis the measured peak concentration during the administration period.

[0206] Example 3 - In vivo animal studies with Compound (Ig) and abiraterone The combination of Compound (Ig) and abiraterone significantly attenuated tumor growth in castrated VCaP xenografts more than either agent alone.

[0207] Example 4 - Toxicity Studies Animals were dosed orally with Compound (Ig) once daily for 28 days, after which the high dose animals were allowed a 14 day recovery period.

[0208] Dogs were given Compound (Ig) orally at 3 mg / kg, 10 mg / kg, or 30 mg / kg once daily. The 30 mg / kg dose was determined to exceed the maximum tolerated dose. Gastrointestinal changes were observed at all dose levels (including vehicle alone). Reversible elevations in liver function enzymes, not considered adverse, were observed in some mid- and high-dose animals. Male animals showed decreased prostate weights, which may be attributable to the pharmacology of Compound (Ig).

[0209] Male rats were orally administered 20 mg / kg, 60 mg / kg, or 120 mg / kg of Compound (Ig) once daily, and female rats were orally administered 20 mg / kg, 40 mg / kg, or 120 mg / kg of Compound (Ig) once daily.

[0210] Overall, Compound (Ig) was well tolerated at all doses, except in the 80 mg / kg female cohort. These rats lost weight and consumed less food. All findings in the high-dose male rats were fully reversible (enlarged liver, thickened femoral epiphyseal cartilage). Male rats also showed a decrease in prostate weight, which may be attributable to the pharmacology of Compound (Ig).

[0211] Example 5 - Phase I Clinical Trial Study Design with Compound (Ig) A phase I clinical trial with compound (IG) was conducted. A conventional 3 + 3 dose escalation design was implemented. The starting dose of compound (IG) was 35 mg orally administered once daily with food. Dose escalation was dependent on toxicity.

[0212] The primary criteria for this trial were men with metastatic castration-resistant prostate cancer (mCRPC), at least two prior systemic therapies, at least one of which was abiraterone or enzalutamide, and disease progression on the most recent therapy (e.g., rising PSA or two or more new lesions on bone scan).

[0213] The primary objective of this study was to obtain the maximum tolerated dose and recommended Phase II dose of Compound (Ig). Additional objectives included evaluation of overall safety of Compound (Ig), pharmacokinetics, antitumor activity (e.g., PSA, RECIST), and biomarkers, including, for example, AR degradation in CTCs and pre- versus post-treatment biopsies (if available), AR (and other) genetic mutations in ctDNA, and AR-V7 in CTCs.

[0214] Example 6 - Phase I Pharmacokinetic Data - Oral Administration of Compound (Ig) In a Phase I clinical trial, Compound (Ig) was administered orally at doses of 35 mg / day, 70 mg / day, and 140 mg / day. Treatment with 140 mg / day of Compound (Ig) was observed to fall within the preclinical efficacy range associated with tumor growth inhibition.

[0215] Initial pharmacokinetic results are shown in Table 2 below and in Figure 7, which represent the mean concentrations of Compound (Ig) for all three tested doses (35 mg / day, 70 mg / day, and 140 mg / day) over a 24-hour period after administration on Day 15.

[0216] [Table 2] a AUC on day 15 calculated using imputed 24-h values

[0217] Example 7 - Phase I dose escalation study with Compound (Ig) Compound (Ig) was administered orally to human subjects (n=22) at doses of 35 mg / day, 70 mg / day, 140 mg / day, and 280 mg / day.

[0218] In the 35 mg / day cohort (n=3), no dose-limiting toxicities were observed, and no grade 2, 3, or 4 adverse events were observed.

[0219] No dose-limiting toxicities were observed in the 70 mg / day cohort (n=4). One patient experienced a grade 2 adverse event (diarrhea, fatigue, vomiting). One patient experienced a grade 3 adverse event (anemia) unrelated to Compound (Ig) administration.

[0220] No dose-limiting toxicities were observed in the 140 mg / day cohort (n=8). Fifty percent of patients experienced grade 2 adverse events, and one patient experienced a grade 3 adverse event (decreased lymphocyte count). These results do not include one patient in this cohort who was deemed unevaluable and discontinued treatment on Day 1.

[0221] In the 280 mg / day cohort (n=7), one patient experienced dose-limiting toxicity and renal failure, and five patients experienced grade 2 or worse adverse events.

[0222] Example 8 - Evaluation of the best percent change in plasma PSA from pre-treatment levels in patients with mCRPC and subsequent assessment of biomarker status after oral administration of Compound (Ig) Twenty patients were orally administered Compound (Ig) at doses of 35 mg / day, 70 mg / day, 140 mg / day, or 280 mg / day. The best percent change in plasma PSA from pretreatment levels for each of the 20 patients is provided in Figure 8. Patient 19 (second bar from the right) and Patient 20 (far right bar) showed at least a 50% PSA reduction after treatment with Compound (Ig).

[0223] The AR biomarker status of 12 patients who received oral administration of compound (Ig) at a dose of 140 mg / day or more was evaluated. Figure 9 shows the AR biomarker status of these 12 patients, along with the best change rate of plasma PSA level. Patients with different AR biomarker status had different responses to treatment with compound (Ig). In this study, for example, only patient 19 (second bar from the right) and patient 20 (rightmost bar), who had both AR mutations T878A and H875Y, had at least a 50% decrease in PSA after treatment.

[0224] Key characteristics of patients 19 and 20 are summarized in Figures 10 and 11A, respectively. Figure 11B shows a CT scan of the tumor from patient 20 before treatment with compound (Ig). Figure 11C shows a CT scan of the tumor from patient 20 after four cycles, demonstrating the RECIST response.

[0225] Example 9 - Further Pharmacokinetic Data - Oral Administration of Compound (Ig) Compound (Ig) was orally administered at doses of 35 mg / day, 70 mg / day, 140 mg / day, and 280 mg / day. Treatment with Compound (Ig) at doses of 140 mg / day and 280 mg / day was observed to fall within the preclinical efficacy range associated with tumor growth inhibition (FIG. 12). The mean plasma concentrations of Compound (Ig) over a 24-hour period after administration on Day 15 for all four doses tested (35 mg / day, 70 mg / day, 140 mg / day, and 280 mg / day) are provided in FIG. 13.
