ESTROGEN RECEPTOR DEGRADERS, PHARMACEUTICAL COMPOSITIONS, AND THERAPEUTIC APPLICATIONS CROSS REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit of the priority of U.S. Provisional Application No.63/235,624, filed August 20, 2021; the disclosure of which is incorporated herein by reference in its entirety. FIELD [0002] Provided herein are estrogen receptor degraders and pharmaceutical compositions thereof. Also provided herein are methods of their use for treating, preventing, or ameliorating one or more symptoms of an estrogen receptor-mediated disorder, disease, or condition. BACKGROUND [0003] Estrogen is a steroid hormone that plays a critical role in reproductive development, bone homeostasis, cardiovascular remodeling, and brain functions. Hua et al., Exp. Hematol. Oncol.2018, 7, 24. Estrogen also plays a vital role in cancer development and progression. Folkerd and Dowsett, J. Clin. Oncol.2010, 28, 4038-44; Hua et al., Exper. Hemat. Oncol.2018, 7, 24; Piggoot et al., Clin. Cancer Res.2018, 24, 2452-63. The biological effects of estrogen are mostly mediated by its binding and activation of an estrogen receptor (ER). Hewitt and Korach, Endocr. Rev.2018, 39, 664-75. In mammals, there are two ERs, ERα and Erβ, both members of the nuclear receptor superfamily of hormone-inducible transcription factors. Aranda and Pascual, Physiol. Rev.2001, 81, 1269-304; Hewitt and Korach, Endocr. Rev.2018, 39, 664-75. [0004] Breast cancer is one of the most common cancer in women worldwide. Harbeck et al., Nat. Rev. Dis. Primers 2019, 5, 66. According to the World Health Organization, in 2020, there were 2.3 million women diagnosed with breast cancer and 685000 deaths globally. Approximately 75% of breast cancer are ERα-positive at diagnosis. Hua et al., Exp. Hematol. Oncol.2018, 7, 24; Harbeck et al., Nat. Rev. Dis. Primers 2019, 5, 66. Endocrine therapy is the first-line treatment for ERα-positive breast cancer. Shagufta et al., RSC Med. Chem.2020, 11, 438-54. Unfortunately, up to 50% of ERα-positive breast cancer patients following initial responsiveness become resistant to endocrine therapy within 5 years. Piggoot et al., Clin. Cancer Res.2018, 24, 2452-63; Szostakowska et al., Breast Cancer Res. Treat.2019, 173, 489- 97; Lu and Liu, J. Med. Chem.2020, 63, 15094-114. Such acquired resistance is associated with poor prognosis and remains an area of an unmet clinical need. Piggoot et al., Clin. Cancer Res. 2018, 24, 2452-63; Harbeck et al., Nat. Rev. Disease Primers 2019, 5.66; Shagufta et al., RSC Med. Chem.2020, 11, 438-54. Therefore, there is a need for an effective therapy for breast cancer, especially recurrent ERα-positive breast cancer.

DETAILED DESCRIPTION [0011] To facilitate understanding of the disclosure set forth herein, a number of terms are defined below. [0012] Generally, the nomenclature used herein and the laboratory procedures in organic chemistry, medicinal chemistry, biochemistry, biology, and pharmacology described herein are those well-known and commonly employed in the art. Unless defined otherwise, all technical and scientific terms used herein generally have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. [0013] The term “subject” refers to an animal, including, but not limited to, a primate (e.g., human), cow, pig, sheep, goat, horse, dog, cat, rabbit, rat, or mouse. The terms “subject” and “patient” are used interchangeably herein in reference, for example, to a mammalian subject, such as a human subject. In one embodiment, the subject is a human. [0014] The terms “treat,” “treating,” and “treatment” are meant to include alleviating or abrogating a disorder, disease, or condition, or one or more of the symptoms associated with the disorder, disease, or condition; or alleviating or eradicating the cause(s) of the disorder, disease, or condition itself. [0015] The terms “prevent,” “preventing,” and “prevention” are meant to include a method of delaying and/or precluding the onset of a disorder, disease, or condition, and/or its attendant symptoms; barring a subject from acquiring a disorder, disease, or condition; or reducing a subject’s risk of acquiring a disorder, disease, or condition. [0016] The terms “alleviate” and “alleviating” refer to easing or reducing one or more symptoms (e.g., pain) of a disorder, disease, or condition. The terms can also refer to reducing adverse effects associated with an active ingredient. Sometimes, the beneficial effects that a subject derives from a prophylactic or therapeutic agent do not result in a cure of the disorder, disease, or condition. [0017] The term “contacting” or “contact” is meant to refer to bringing together of a therapeutic agent and a biological molecule (e.g., a protein, enzyme, RNA, or DNA), cell, or tissue such that a physiological and/or chemical effect takes place as a result of such contact. Contacting can take place in vitro, ex vivo, or in vivo. In one embodiment, a therapeutic agent is contacted with a biological molecule in vitro to determine the effect of the therapeutic agent on the biological molecule. In another embodiment, a therapeutic agent is contacted with a cell in cell culture (in vitro) to determine the effect of the therapeutic agent on the cell. In yet another embodiment, the contacting of a therapeutic agent with a biological molecule, cell, or tissue includes the administration of a therapeutic agent to a subject having the biological molecule, cell, or tissue to be contacted. [0018] The term “therapeutically effective amount” or “effective amount” is meant to include the amount of a compound that, when administered, is sufficient to prevent development of, or alleviate to some extent, one or more of the symptoms of the disorder, disease, or condition being treated. The term “therapeutically effective amount” or “effective amount” also refers to the amount of a compound that is sufficient to elicit a biological or medical response of a biological molecule (e.g., a protein, enzyme, RNA, or DNA), cell, tissue, system, animal, or human, which is being sought by a researcher, veterinarian, medical doctor, or clinician. [0019] The term “IC ₅₀ ” or “EC ₅₀ ” refers to an amount, concentration, or dosage of a compound that is required for 50% inhibition of a maximal response in an assay that measures such a response. [0020] The term “pharmaceutically acceptable carrier,” “pharmaceutically acceptable excipient,” “physiologically acceptable carrier,” or “physiologically acceptable excipient” refers to a pharmaceutically acceptable material, composition, or vehicle, such as a liquid or solid filler, diluent, solvent, or encapsulating material. In one embodiment, each component is “pharmaceutically acceptable” in the sense of being compatible with the other ingredients of a pharmaceutical formulation, and suitable for use in contact with the tissue or organ of a subject (e.g., a human) without excessive toxicity, irritation, allergic response, immunogenicity, or other problems or complications, and commensurate with a reasonable benefit/risk ratio.

[0045] In certain embodiments, “optically active” and ”enantiomerically active” refer to a collection of molecules, which has an enantiomeric excess of no less than about 80%, no less than about 90%, no less than about 91%, no less than about 92%, no less than about 93%, no less than about 94%, no less than about 95%, no less than about 96%, no less than about 97%, no less than about 98%, no less than about 99%, no less than about 99.5%, or no less than about 99.8%. In certain embodiments, an optically active compound comprises about 95% or more of one enantiomer and about 5% or less of the other enantiomer based on the total weight of the enantiomeric mixture in question. In certain embodiments, an optically active compound comprises about 98% or more of one enantiomer and about 2% or less of the other enantiomer based on the total weight of the enantiomeric mixture in question. In certain embodiments, an optically active compound comprises about 99% or more of one enantiomer and about 1% or less of the other enantiomer based on the total weight of the enantiomeric mixture in question. [0046] In describing an optically active compound, the prefixes R and S are used to denote the absolute configuration of the compound about its chiral center(s). The (+) and (-) are used to denote the optical rotation of the compound, that is, the direction in which a plane of polarized light is rotated by the optically active compound. The (-) prefix indicates that the compound is levorotatory, that is, the compound rotates the plane of polarized light to the left or counterclockwise. The (+) prefix indicates that the compound is dextrorotatory, that is, the compound rotates the plane of polarized light to the right or clockwise. However, the sign of optical rotation, (+) and (-), is not related to the absolute configuration of the compound, R and S. [0047] The term “isotopically enriched” refers to a compound that contains an unnatural proportion of an isotope at one or more of the atoms that constitute such a compound. In certain embodiments, an isotopically enriched compound contains unnatural proportions of one or more isotopes, including, but not limited to, hydrogen ( ¹ H), deuterium ( ² H), tritium ( ³ H), carbon-11 ( ¹¹ C), carbon-12 ( ¹² C), carbon-13 ( ¹³ C), carbon-14 ( ¹⁴ C), nitrogen-13 ( ¹³ N), nitrogen-14 ( ¹⁴ N), nitrogen-15 ( ¹⁵ N), oxygen-14 ( ¹⁴ O), oxygen-15 ( ¹⁵ O), oxygen-16 ( ¹⁶ O), oxygen-17 ( ¹⁷ O), oxygen-18 ( ¹⁸ O), fluorine-17 ( ¹⁷ F), fluorine-18 ( ¹⁸ F), phosphorus-31 ( ³¹ P), phosphorus-32 ( ³² P), phosphorus-33 ( ³³ P), sulfur-32 ( ³² S), sulfur-33 ( ³³ S), sulfur-34 ( ³⁴ S), sulfur-35 ( ³⁵ S), sulfur-36 ( ³⁶ S), chlorine-35 ( ³⁵ Cl), chlorine-36 ( ³⁶ Cl), chlorine-37 ( ³⁷ Cl), bromine-79 ( ⁷⁹ Br), bromine-81 ( ⁸¹ Br), iodine-123 ( ¹²³ I), iodine-125 ( ¹²⁵ I), iodine-127 ( ¹²⁷ I), iodine-129 ( ¹²⁹ I), and iodine-131 ( ¹³¹ I). In certain embodiments, an isotopically enriched compound is in a stable form, that is, non-radioactive. In certain embodiments, an isotopically enriched compound contains unnatural proportions of one or more isotopes, including, but not limited to, hydrogen ( ¹ H), deuterium ( ² H), carbon-12 ( ¹² C), carbon-13 ( ¹³ C), nitrogen-14 ( ¹⁴ N), nitrogen-15 ( ¹⁵ N), oxygen-16 ( ¹⁶ O), oxygen-17 ( ¹⁷ O), oxygen-18 ( ¹⁸ O), fluorine-17 ( ¹⁷ F), phosphorus-31 ( ³¹ P), sulfur-32 ( ³² S), sulfur- 33 ( ³³ S), sulfur-34 ( ³⁴ S), sulfur-36 ( ³⁶ S), chlorine-35 ( ³⁵ Cl), chlorine-37 ( ³⁷ Cl), bromine-79 ( ⁷⁹ Br), bromine-81 ( ⁸¹ Br), and iodine-127 ( ¹²⁷ I). In certain embodiments, an isotopically enriched compound is in an unstable form, that is, radioactive. In certain embodiments, an isotopically enriched compound contains unnatural proportions of one or more isotopes, including, but not limited to, tritium ( ³ H), carbon-11 ( ¹¹ C), carbon-14 ( ¹⁴ C), nitrogen-13 ( ¹³ N), oxygen-14 ( ¹⁴ O), oxygen-15 ( ¹⁵ O), fluorine-18 ( ¹⁸ F), phosphorus-32 ( ³² P), phosphorus-33 ( ³³ P), sulfur-35 ( ³⁵ S), chlorine-36 ( ³⁶ Cl), iodine-123 ( ¹²³ I), iodine-125 ( ¹²⁵ I), iodine-129 ( ¹²⁹ I), and iodine-131 ( ¹³¹ I). It will be understood that, in a compound as provided herein, any hydrogen can be ² H, as example, or any carbon can be ¹³ C, as example, or any nitrogen can be ¹⁵ N, as example, or any oxygen can be ¹⁸ O, as example, where feasible according to the judgment of one of ordinary skill in the art. [0048] The term “isotopic enrichment” refers to the percentage of incorporation of a less prevalent isotope (e.g., D for deuterium or hydrogen-2) of an element at a given position in a molecule in the place of a more prevalent isotope (e.g., ¹ H for protium or hydrogen-1) of the element. As used herein, when an atom at a particular position in a molecule is designated as a particular less prevalent isotope, it is understood that the abundance of that isotope at that position is substantially greater than its natural abundance. [0049] The term “isotopic enrichment factor” refers the ratio between the isotopic abundance in an isotopically enriched compound and the natural abundance of a specific isotope. [0050] The term “hydrogen” or the symbol “H” refers to the composition of naturally occurring hydrogen isotopes, which include protium ( ¹ H), deuterium ( ² H or D), and tritium ( ³ H), in their natural abundances. Protium is the most common hydrogen isotope having a natural abundance of more than 99.98%. Deuterium is a less prevalent hydrogen isotope having a natural abundance of about 0.0156%. [0051] The term “deuterium enrichment” refers to the percentage of incorporation of deuterium at a given position in a molecule in the place of hydrogen. For example, deuterium enrichment of 1% at a given position means that 1% of molecules in a given sample contain deuterium at the specified position. Because the naturally occurring distribution of deuterium is about 0.0156% on average, deuterium enrichment at any position in a compound synthesized using non-enriched starting materials is about 0.0156% on average. As used herein, when a particular position in an isotopically enriched compound is designated as having deuterium, it is understood that the abundance of deuterium at that position in the compound is substantially greater than its natural abundance (0.0156%). [0052] The term “carbon” or the symbol “C” refers to the composition of naturally occurring carbon isotopes, which include carbon-12 ( ¹² C) and carbon-13 ( ¹³ C) in their natural abundances. Carbon-12 is the most common carbon isotope having a natural abundance of more than 98.89%. Carbon-13 is a less prevalent carbon isotope having a natural abundance of about 1.11%. [0053] The term “carbon-13 enrichment” or “ ¹³ C enrichment” refers to the percentage of incorporation of carbon-13 at a given position in a molecule in the place of carbon. For example, carbon-13 enrichment of 10% at a given position means that 10% of molecules in a given sample contain carbon-13 at the specified position. Because the naturally occurring distribution of carbon-13 is about 1.11% on average, carbon-13 enrichment at any position in a compound synthesized using non-enriched starting materials is about 1.11% on average. As used herein, when a particular position in an isotopically enriched compound is designated as having carbon- 13, it is understood that the abundance of carbon-13 at that position in the compound is substantially greater than its natural abundance (1.11%). [0054] The terms “substantially pure” and “substantially homogeneous” mean, when referred to a substance, sufficiently homogeneous to appear free of readily detectable impurities as determined by a standard analytical method used by one of ordinary skill in the art, including, but not limited to, thin layer chromatography (TLC), gel electrophoresis, high performance liquid chromatography (HPLC), gas chromatography (GC), nuclear magnetic resonance (NMR), and mass spectrometry (MS); or sufficiently pure such that further purification would not detectably alter the physical, chemical, biological, and/or pharmacological properties, such as enzymatic and biological activities, of the substance. In certain embodiments, “substantially pure” or “substantially homogeneous” refers to a collection of molecules, wherein at least about 95%, at least about 96%, at least about 97%, at least about 98%, at least about 99%, or at least about 99.5% by weight of the molecules are a single compound, including a single enantiomer, a racemic mixture, or a mixture of enantiomers, as determined by standard analytical methods. As used herein, when an atom at a particular position in an isotopically enriched molecule is designated as a particular less prevalent isotope, a molecule that contains other than the designated isotope at the specified position is an impurity with respect to the isotopically enriched compound. Thus, for a deuterated compound that has an atom at a particular position designated as deuterium, a compound that contains a protium at the same position is an impurity. [0055] The term “solvate” refers to a complex or aggregate formed by one or more molecules of a solute, e.g., a compound provided herein, and one or more molecules of a solvent, which are present in a stoichiometric or non-stoichiometric amount. Suitable solvents include, but are not limited to, water, methanol, ethanol, n-propanol, isopropanol, and acetic acid. In certain embodiments, the solvent is pharmaceutically acceptable. In one embodiment, the complex or aggregate is in a crystalline form. In another embodiment, the complex or aggregate is in a noncrystalline form. Where the solvent is water, the solvate is a hydrate. Examples of hydrates include, but are not limited to, a hemihydrate, monohydrate, dihydrate, trihydrate, tetrahydrate, and pentahydrate. [0056] For a divalent group described herein, no orientation is implied by the direction in which the divalent group is presented. For example, unless a particular orientation is specified, the formula –C(O)NH– represents both –C(O)NH– and – NHC(O)–. [0057] The phrase “an enantiomer, a mixture of enantiomers, a mixture of two or more diastereomers, a tautomer, a mixture of two or more tautomers, or an isotopic variant thereof; or a pharmaceutically acceptable salt, solvate, hydrate, or prodrug thereof” has the same meaning as the phrase “(i) an enantiomer, a mixture of enantiomers, a mixture of two or more diastereomers, a tautomer, a mixture of two or more tautomers, or an isotopic variant of the compound referenced therein; (ii) a pharmaceutically acceptable salt, solvate, hydrate, or prodrug of the compound referenced therein; or (iii) a pharmaceutically acceptable salt, solvate, hydrate, or prodrug of an enantiomer, a mixture of enantiomers, a mixture of two or more diastereomers, a tautomer, a mixture of two or more tautomers, or an isotopic variant of the compound referenced therein.” Compounds [0058] In one embodiment, provided herein is a compound of Formula (I): R ^T –L–R ^E (I) or an enantiomer, a mixture of enantiomers, a diastereomer, a mixture of two or more diastereomers, a tautomer, a mixture of two or more tautomers, or an isotopic variant thereof; or a pharmaceutically acceptable salt, solvate, hydrate, or prodrug thereof; wherein: L is a linker; R ^E is an E3 ubiquitin ligase binding moiety; and R ^T is a moiety of the structure of any one of Formulae (i) to (xv):

[00318] In certain embodiments, a compound provided herein is deuterium-enriched. In certain embodiments, a compound provided herein is carbon-13 enriched. In certain embodiments, a compound provided herein is carbon-14 enriched. In certain embodiments, a compound provided herein contains one or more less prevalent isotopes for other elements, including, but not limited to, ¹⁵ N for nitrogen; ¹⁷ O or ¹⁸ O for oxygen, and ³⁴ S, ³⁵ S, or ³⁶ S for sulfur. [00319] In certain embodiments, a compound provided herein has an isotopic enrichment factor of no less than about 5, no less than about 10, no less than about 20, no less than about 50, no less than about 100, no less than about 200, no less than about 500, no less than about 1,000, no less than about 2,000, no less than about 5,000, or no less than about 10,000. In any events, however, an isotopic enrichment factor for a specified isotope is no greater than the maximum isotopic enrichment factor for the specified isotope, which is the isotopic enrichment factor when a compound at a given position is 100% enriched with the specified isotope. Thus, the maximum isotopic enrichment factor is different for different isotopes. The maximum isotopic enrichment factor is 6,410 for deuterium and 90 for carbon-13. [00320] In certain embodiments, a compound provided herein has a deuterium enrichment factor of no less than about 64 (about 1% deuterium enrichment), no less than about 130 (about 2% deuterium enrichment), no less than about 320 (about 5% deuterium enrichment), no less than about 640 (about 10% deuterium enrichment), no less than about 1,300 (about 20% deuterium enrichment), no less than about 3,200 (about 50% deuterium enrichment), no less than about 4,800 (about 75% deuterium enrichment), no less than about 5,130 (about 80% deuterium enrichment), no less than about 5,450 (about 85% deuterium enrichment), no less than about 5,770 (about 90% deuterium enrichment), no less than about 6,090 (about 95% deuterium enrichment), no less than about 6,220 (about 97% deuterium enrichment), no less than about 6,280 (about 98% deuterium enrichment), no less than about 6,350 (about 99% deuterium enrichment), or no less than about 6,380 (about 99.5% deuterium enrichment). The deuterium enrichment can be determined using conventional analytical methods known to one of ordinary skill in the art, including mass spectrometry and nuclear magnetic resonance spectroscopy. In certain embodiments, at least one of the atoms of a compound provided herein, as specified as deuterium-enriched, has deuterium enrichment of no less than about 50%, no less than about 70%, no less than about 80%, no less than about 90%, or no less than about 98%. [00321] In certain embodiments, a compound provided herein is isolated or purified. In certain embodiments, a compound provided herein has a purity of at least about 90%, at least about 95%, at least about 98%, at least about 99%, or at least about 99.5% by weight. [00322] The compounds provided herein are intended to encompass all possible stereoisomers unless a particular stereochemistry is specified. Where a compound provided herein contains an alkenyl group, the compound may exist as one or mixture of geometric cis/trans (or Z/E) isomers. Where structural isomers are interconvertible, the compound may exist as a single tautomer or a mixture of tautomers. This can take the form of proton tautomerism in the compound that contains, for example, an imino, keto, or oxime group; or so- called valence tautomerism in the compound that contains an aromatic moiety. It follows that a single compound may exhibit more than one type of isomerism. [00323] A compound provided herein can be enantiomerically pure, such as a single enantiomer or a single diastereomer, or be stereoisomeric mixtures, such as a mixture of enantiomers, e.g., a racemic mixture of two enantiomers; or a mixture of two or more diastereomers. As such, one of ordinary skill in the art will recognize that administration of a compound in its (R) form is equivalent, for the compound that undergoes epimerization in vivo, to administration of the compound in its (S) form. Conventional techniques for the preparation/isolation of individual enantiomers include synthesis from a suitable optically pure precursor, asymmetric synthesis from achiral starting materials, or resolution of an enantiomeric mixture, for example, chiral chromatography, recrystallization, resolution, diastereomeric salt formation, or derivatization into diastereomeric adducts followed by separation. [00324] When a compound provided herein contains an acidic or basic moiety, it can also be provided as a pharmaceutically acceptable salt. See, Berge et al., J. Pharm. Sci.1977, 66, 1- 19; Handbook of Pharmaceutical Salts: Properties, Selection, and Use, 2nd ed.; Stahl and Wermuth Eds.; John Wiley & Sons, 2011. In certain embodiments, a pharmaceutically acceptable salt of a compound provided herein is a solvate.

[00327] A compound provided herein may also be provided as a prodrug, which is a functional derivative of the compound and is readily convertible into the parent compound in vivo. Prodrugs are often useful because, in some situations, they may be easier to administer than the parent compound. They may, for instance, be bioavailable by oral administration whereas the parent compound is not. The prodrug may also have enhanced solubility in pharmaceutical compositions over the parent compound. A prodrug may be converted into the parent drug by various mechanisms, including enzymatic processes and metabolic hydrolysis. Pharmaceutical Compositions [00328] In one embodiment, provided herein is a pharmaceutical composition, comprising a compound provided herein, e.g., a compound of Formula (I), or an enantiomer, a mixture of enantiomers, a diastereomer, a mixture of two or more diastereomers, a tautomer, a mixture of two or more tautomers, or an isotopic variant thereof; or a pharmaceutically acceptable salt, solvate, hydrate, or prodrug thereof; and a pharmaceutically acceptable excipient.

[00378] Materials useful in forming an erodible matrix include, but are not limited to, chitin, chitosan, dextran, and pullulan; gum agar, gum arabic, gum karaya, locust bean gum, gum tragacanth, carrageenans, gum Ghatti, guar gum, xanthan gum, and scleroglucan; starches, such as dextrin and maltodextrin; hydrophilic colloids, such as pectin; phosphatides, such as lecithin; alginates; propylene glycol alginate; gelatin; collagen; cellulosics, such as ethyl cellulose (EC), methylethyl cellulose (MEC), carboxymethyl cellulose (CMC), CMEC, hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), cellulose acetate (CA), cellulose propionate (CP), cellulose butyrate (CB), cellulose acetate butyrate (CAB), CAP, CAT, hydroxypropyl methyl cellulose (HPMC), HPMCP, HPMCAS, hydroxypropyl methyl cellulose acetate trimellitate (HPMCAT), and ethyl hydroxyethyl cellulose (EHEC); polyvinyl pyrrolidone; polyvinyl alcohol; polyvinyl acetate; glycerol fatty acid esters; polyacrylamide; polyacrylic acid; copolymers of ethacrylic acid or methacrylic acid (EUDRAGIT®); poly(2-hydroxyethyl- methacrylate); polylactides; copolymers of L-glutamic acid and ethyl-L-glutamate; degradable lactic acid-glycolic acid copolymers; poly-D-(-)-3-hydroxybutyric acid; and other acrylic acid derivatives, such as homopolymers and copolymers of butylmethacrylate, methyl methacrylate, ethyl methacrylate, ethylacrylate, (2-dimethylaminoethyl)methacrylate, and (trimethylaminoethyl)methacrylate chloride. [00379] In certain embodiments, the pharmaceutical composition provided herein is formulated with a non-erodible matrix device. The active ingredient(s) is dissolved or dispersed in an inert matrix and is released primarily by diffusion through the inert matrix once administered. Materials suitable for use as a non-erodible matrix device include, but are not limited to, insoluble plastics, such as polyethylene, polypropylene, polyisoprene, polyisobutylene, polybutadiene, polymethylmethacrylate, polybutylmethacrylate, chlorinated polyethylene, polyvinylchloride, methyl acrylate-methyl methacrylate copolymers, ethylene- vinyl acetate copolymers, ethylene/propylene copolymers, ethylene/ethyl acrylate copolymers, vinyl chloride copolymers with vinyl acetate, vinylidene chloride, ethylene and propylene, ionomer polyethylene terephthalate, butyl rubbers, epichlorohydrin rubbers, ethylene/vinyl alcohol copolymer, ethylene/vinyl acetate/vinyl alcohol terpolymer, ethylene/vinyloxyethanol copolymer, polyvinyl chloride, plasticized nylon, plasticized polyethylene terephthalate, natural rubber, silicone rubbers, polydimethylsiloxanes, and silicone carbonate copolymers; hydrophilic polymers, such as ethyl cellulose, cellulose acetate, crospovidone, and cross-linked partially hydrolyzed polyvinyl acetate; and fatty compounds, such as carnauba wax, microcrystalline wax, and triglycerides. [00380] In a matrix-controlled release system, the desired release kinetics can be controlled, for example, via the polymer type employed, the polymer viscosity, the particle sizes of the polymer and/or the active ingredient(s), the ratio of the active ingredient(s) versus the polymer, and other excipients or carriers in the compositions. [00381] The pharmaceutical composition provided herein in a modified release dosage form can be prepared by methods known to those skilled in the art, including direct compression, dry or wet granulation followed by compression, and melt-granulation followed by compression. 2. Osmotic Controlled Release Devices [00382] The pharmaceutical composition provided herein in a modified release dosage form can be fabricated using an osmotic controlled release device, including, but not limited to, one-chamber system, two-chamber system, asymmetric membrane technology (AMT), and extruding core system (ECS). In general, such devices have at least two components: (a) a core which contains an active ingredient; and (b) a semipermeable membrane with at least one delivery port, which encapsulates the core. The semipermeable membrane controls the influx of water to the core from an aqueous environment of use so as to cause drug release by extrusion through the delivery port(s). [00383] In addition to the active ingredient(s), the core of the osmotic device optionally includes an osmotic agent, which creates a driving force for transport of water from the environment of use into the core of the device. One class of osmotic agents is water-swellable hydrophilic polymers, which are also referred to as “osmopolymers” and “hydrogels.” Suitable water-swellable hydrophilic polymers as osmotic agents include, but are not limited to, hydrophilic vinyl and acrylic polymers, polysaccharides such as calcium alginate, polyethylene oxide (PEO), polyethylene glycol (PEG), polypropylene glycol (PPG), poly(2-hydroxyethyl methacrylate), poly(acrylic) acid, poly(methacrylic) acid, polyvinylpyrrolidone (PVP), crosslinked PVP, polyvinyl alcohol (PVA), PVA/PVP copolymers, PVA/PVP copolymers with hydrophobic monomers such as methyl methacrylate and vinyl acetate, hydrophilic polyurethanes containing large PEO blocks, sodium croscarmellose, carrageenan, hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), hydroxypropyl methyl cellulose (HPMC), carboxymethyl cellulose (CMC) and carboxyethyl, cellulose (CEC), sodium alginate, polycarbophil, gelatin, xanthan gum, and sodium starch glycolate. [00384] The other class of osmotic agents is osmogens, which are capable of imbibing water to affect an osmotic pressure gradient across the barrier of the surrounding coating. Suitable osmogens include, but are not limited to, inorganic salts, such as magnesium sulfate, magnesium chloride, calcium chloride, sodium chloride, lithium chloride, potassium sulfate, potassium phosphates, sodium carbonate, sodium sulfite, lithium sulfate, potassium chloride, and sodium sulfate; sugars, such as dextrose, fructose, glucose, inositol, lactose, maltose, mannitol, raffinose, sorbitol, sucrose, trehalose, and xylitol; organic acids, such as ascorbic acid, benzoic acid, fumaric acid, citric acid, maleic acid, sebacic acid, sorbic acid, adipic acid, edetic acid, glutamic acid, p-toluenesulfonic acid, succinic acid, and tartaric acid; urea; and mixtures thereof. [00385] Osmotic agents of different dissolution rates can be employed to influence how rapidly the active ingredient(s) is initially delivered from the dosage form. For example, amorphous sugars, such as MANNOGEM ^™ EZ can be used to provide faster delivery during the first couple of hours to promptly produce the desired therapeutic effect, and gradually and continually release of the remaining amount to maintain the desired level of therapeutic or prophylactic effect over an extended period of time. In this case, the active ingredient(s) is released at such a rate to replace the amount of the active ingredient metabolized and excreted. [00386] The core can also include a wide variety of other excipients and carriers as described herein to enhance the performance of the dosage form or to promote stability or processing. [00387] Materials useful in forming the semipermeable membrane include various grades of acrylics, vinyls, ethers, polyamides, polyesters, and cellulosic derivatives that are water- permeable and water-insoluble at physiologically relevant pHs or are susceptible to being rendered water-insoluble by chemical alteration, such as crosslinking. Examples of suitable polymers useful in forming the coating, include plasticized, unplasticized, and reinforced cellulose acetate (CA), cellulose diacetate, cellulose triacetate, CA propionate, cellulose nitrate, cellulose acetate butyrate (CAB), CA ethyl carbamate, CAP, CA methyl carbamate, CA succinate, cellulose acetate trimellitate (CAT), CA dimethylaminoacetate, CA ethyl carbonate, CA chloroacetate, CA ethyl oxalate, CA methyl sulfonate, CA butyl sulfonate, CA p-toluene sulfonate, agar acetate, amylose triacetate, beta glucan acetate, beta glucan triacetate, acetaldehyde dimethyl acetate, triacetate of locust bean gum, hydroxylated ethylene-vinylacetate, EC, PEG, PPG, PEG/PPG copolymers, PVP, HEC, HPC, CMC, CMEC, HPMC, HPMCP, HPMCAS, HPMCAT, poly(acrylic) acids and esters and poly-(methacrylic) acids and esters and copolymers thereof, starch, dextran, dextrin, chitosan, collagen, gelatin, polyalkenes, polyethers, polysulfones, polyethersulfones, polystyrenes, polyvinyl halides, polyvinyl esters and ethers, natural waxes, and synthetic waxes. [00388] Semipermeable membrane can also be a hydrophobic microporous membrane, wherein the pores are substantially filled with a gas and are not wetted by the aqueous medium but are permeable to water vapor, as disclosed in U.S. Pat. No.5,798,119. Such hydrophobic but water-vapor permeable membrane are typically composed of hydrophobic polymers such as polyalkenes, polyethylene, polypropylene, polytetrafluoroethylene, polyacrylic acid derivatives, polyethers, polysulfones, polyethersulfones, polystyrenes, polyvinyl halides, polyvinylidene fluoride, polyvinyl esters and ethers, natural waxes, and synthetic waxes. [00389] The delivery port(s) on the semipermeable membrane can be formed post-coating by mechanical or laser drilling. Delivery port(s) can also be formed in situ by erosion of a plug of water-soluble material or by rupture of a thinner portion of the membrane over an indentation in the core. In addition, delivery ports can be formed during coating process, as in the case of asymmetric membrane coatings of the type disclosed in U.S. Pat. Nos.5,612,059 and 5,698,220. [00390] The total amount of the active ingredient(s) released and the release rate can substantially by modulated via the thickness and porosity of the semipermeable membrane, the composition of the core, and the number, size, and position of the delivery ports. [00391] The pharmaceutical composition in an osmotic controlled-release dosage form can further comprise additional conventional excipients or carriers as described herein to promote performance or processing of the formulation. [00392] The osmotic controlled-release dosage forms can be prepared according to conventional methods and techniques known to those skilled in the art. See, e.g., Remington: The Science and Practice of Pharmacy, supra; Santus and Baker, J. Controlled Release, 1995, 35, 1-21; Verma et al., Drug Dev. Ind. Pharm., 2000, 26, 695-708; Verma et al., J. Controlled Release, 2002, 79, 7-27. [00393] In certain embodiments, the pharmaceutical composition provided herein is formulated as an AMT controlled-release dosage form, which comprises an asymmetric osmotic membrane that coats a core comprising the active ingredient(s) and other pharmaceutically acceptable excipients or carriers.

Example B2 Protein Degradation Assay [00657] A compound provided herein was assessed for its activity in degrading an ERα in MCF-7 cells via a western blot. The MCF7 cells were cultured at 37 °C in a humidified 5% CO ₂ environment in MEM supplemented with 10% FBS with insulin. The cells were seeded in 12-well plates at a density of 300,000 cells per well in maintenance media. Cells were treated with the compound at predetermined concentrations (e.g., 1 nM, 10 nM, 100 nM, and 1 µM) for 6 h. The cells were then washed in PBS and the whole cells were lysed in a cell lysis buffer and incubated for 15 minutes on ice. Cell debris was removed by high-speed centrifugation and the cleared whole cell lysates were prepared for further analysis by a western blot. The whole cell protein extracts were separated on SDS-polyacrylamide gels, transferred to nitrocellulose membranes, and probed with primary antibodies, including anti-ERα antibody and GAPDH antibody for loading control. The membranes were subsequently washed and probed with secondary antibodies for chemiluminescence, followed by imaging on a BIORAD CHEMIDOC Imaging System. The results are summarized in Table 2, where “A” represents a percentage degradation value of no less than 50%; “B” represents a percentage degradation value of less than 50% and no less than 25%; “C” represents a percentage degradation value of less than 25% and no less than 10%; and “D” represents a percentage degradation value of less than 10%.
