FIELD OF THE INVENTION
Field of the Invention

The present disclosure generally relates to pharmaceutical compositions and combinations comprising an androgen receptor (AR) N-terminal domain inhibitor (NTD) Compound A and an additional therapeutic agent, such as an antiandrogen. In particular, the present disclosure relates to pharmaceutical compositions and combinations useful for treatment of various cancers, such as prostate cancer.

Background of the Invention

Androgens mediate their effects through the androgen receptor (AR). Androgens play a role in a wide range of developmental and physiological responses and are involved in male sexual differentiation, maintenance of spermatogenesis, and male gonadotropin regulation (R. K. Ross, G. A. Coetzee, C. L. Pearce, J. K. Reichardt, P. Bretsky, L. N. Kolonel, B. E. Henderson, E. Lander, D. Altshuler & G. Daley, Eur Urol 35, 355-361 (1999); A. A. Thomson, Reproduction 121, 187-195 (2001); N. Tanji, K. Aoki & M. Yokoyama, Arch Androl 47, 1-7 (2001)). Several lines of evidence show that androgens are associated with the development of prostate carcinogenesis. Firstly, androgens induce prostatic carcinogenesis in rodent models (R. L. Noble, Cancer Res 37, 1929-1933 (1977); R. L. Noble, Oncology 34, 138-141 (1977)) and men receiving androgens in the form of anabolic steroids have a higher incidence of prostate cancer (J. T. Roberts & D. M. Essenhigh, Lancet 2, 742 (1986); J. A. Jackson, J. Waxman & A. M. Spiekerman, Arch Intern Med 149, 2365-2366 (1989); P. D. Guinan, W. Sadoughi, H. Alsheik, R. J. Ablin, D. Alrenga & I. M. Bush, Am J Surg 131, 599-600 (1976)). Secondly, prostate cancer does not develop if humans or dogs are castrated before puberty (J. D. Wilson & C. Roehrborn, J Clin Endocrinol Metab 84, 4324-4331 (1999); G. Wilding, Cancer Surv 14, 113-130 (1992)). Castration of adult males causes involution of the prostate and apoptosis of prostatic epithelium while eliciting no effect on other male external genitalia (E. M. Bruckheimer & N. Kyprianou, Cell Tissue Res 301, 153-162 (2000); J. T. Isaacs, Prostate 5, 545-557 (1984)). This dependency on androgens provides the underlying rationale for treating prostate cancer with chemical or surgical castration also known as androgen ablation therapy (ABT) or androgen deprivation therapy (ADT).

Androgen receptor (AR) is a transcription factor that plays dual roles in breast cancer cells: promoting or inhibiting proliferation depending on expression and activity of estrogen receptor-alpha. Currently there is no FDA-approved targeted therapy for triple-negative breast cancer (TNBC). AR plays a role in the proliferation of breast cancer cells by either promoting proliferation or inhibiting proliferation depending on the expression of estrogen receptor (ER) and human epidermal growth factor receptor 2 (HER2). AR expression is detected in up to 90% of all breast cancers and in up to approximately 35% of TNBC. AR-Vs have been detected in primary breast cancer specimens and in breast cancer cell lines. AR-V7 expression was detected in circulating-tumor cells of patients with metastatic breast cancer and was associated with bone metastases. Targeting AR is a potential therapeutic strategy for AR-positive TNBC.

Androgens also play a role in female diseases such as polycystic ovary syndrome as well as cancers. One example is ovarian cancer where elevated levels of androgens are associated with an increased risk of developing ovarian cancer (K. J. Helzlsouer, A. J. Alberg, G. B. Gordon, C. Longcope, T. L. Bush, S. C. Hoffman & G. W. Comstock, JAMA 274, 1926-1930 (1995); R. J. Edmondson, J. M. Monaghan & B. R. Davies, Br J Cancer 86, 879-885 (2002)). The AR has been detected in a majority of ovarian cancers (H. A. Risch, J Natl Cancer Inst 90, 1774-1786 (1998); B. R. Rao & B. J. Slotman, Endocr Rev 12, 14-26 (1991); G. M. Clinton & W. Hua, Crit Rev Oncol Hematol 25, 1-9 (1997)), whereas estrogen receptor-alpha (ERa) and the progesterone receptor are detected in less than 50% of ovarian tumors.

The only effective treatment available for advanced prostate cancer is the withdrawal of androgens which are essential for the survival of prostate luminal cells. Androgen ablation therapy causes a temporary reduction in tumor burden concomitant with a decrease in serum prostate-specific antigen (PSA). Unfortunately, prostate cancer can eventually grow again in the absence of testicular androgens (castration-resistant disease) (Huber et al 1987 Scand J. Urol Nephrol. 104, 33-39). Castration-resistant prostate cancer that is still driven by AR is biochemically characterized before the onset of symptoms by a rising titre of serum PSA (Miller et al 1992 J. Urol. 147, 956-961). Once the disease becomes castration-resistant most patients succumb to their disease within two years.

The AR has distinct functional domains that include the carboxy-terminal ligand-binding domain (LBD), a DNA-binding domain (DBD) comprising two zinc finger motifs, and an N-terminus domain (NTD) that contains two transcriptional activation units (tau1 and tau5) within activation function-1 (AF-1). Binding of androgen (ligand) to the LBD of the AR results in its activation such that the receptor can effectively bind to its specific DNA consensus site, termed the androgen response element (ARE), on the promoter and enhancer regions of “normally” androgen regulated genes, such as PSA, to initiate transcription. The AR can be activated in the absence of androgen by stimulation of the cAMP-dependent protein kinase (PKA) pathway, with interleukin-6 (IL-6) and by various growth factors (Culig et al 1994 Cancer Res. 54, 5474-5478; Nazareth et al 1996 J. Biol. Chem. 271, 19900-19907; Sadar 1999 J. Biol. Chem. 274, 7777-7783; Ueda et al 2002 A J. Biol. Chem. 277, 7076-7085; and Ueda et al 2002 B J. Biol. Chem. 277, 38087-38094). The mechanism of ligand-independent transformation of the AR has been shown to involve: 1) increased nuclear AR protein suggesting nuclear translocation; 2) increased AR/ARE complex formation; and 3) the AR-NTD (Sadar 1999 J. Biol. Chem. 274, 7777-7783; Ueda et al 2002 A J. Biol. Chem. 277, 7076-7085; and Ueda et al 2002 B J. Biol. Chem. 277, 38087-38094). The AR can be activated in the absence of testicular androgens by alternative signal transduction pathways in castration-resistant disease, which is consistent with the finding that nuclear AR protein is present in secondary prostate cancer tumors (Kim et al 2002 Am. J. Pathol. 160, 219-226; and van der Kwast et al 1991 Inter. J. Cancer 48, 189-193).

Clinically available inhibitors of the AR include nonsteroidal antiandrogens such as bicalutamide (Casodex™), nilutamide (Anandron®, Nilandron®), flutamide (Eulexin®), enzalutamide (Xtandi®), apalutamide (Erleada®), and darolutamide (Nubeqa®). There is also a class of steroidal antiandrogens, such as cyproterone acetate and spironolactone. Both steroidal and non-steroidal antiandrogens target the LBD of the AR and predominantly fail presumably due to poor affinity and mutations that lead to activation of the AR by these same antiandrogens (Taplin, M. E., Bubley, G. J., Kom Y. J., Small E. J., Uptonm M., Rajeshkumarm B., Balkm S. P., Cancer Res., 59, 2511-2515 (1999)), and constitutively active AR splice variants. Antiandrogens have no effect on the constitutively active AR splice variants that lack the ligand-binding domain (LBD) and are associated with castration-recurrent prostate cancer (Dehm S M, Schmidt L J, Heemers H V, Vessella R L, Tindall D J., Cancer Res 68, 5469-77, 2008; Guo Z, Yang X, Sun F, Jiang R, Linn D E, Chen H, Chen H, Kong X, Melamed J, Tepper C G, Kung H J, Brodie A M, Edwards J, Qiu Y., Cancer Res. 69, 2305-13, 2009; Hu et al 2009 Cancer Res. 69, 16-22; Sun et al 2010 J Clin Invest. 2010 120, 2715-30) and resistant to abiraterone and enzalutamide (Antonarakis et al., N Engl J Med. 2014, 371, 1028-38; Scher et al JAMA Oncol. 2016 doi: 10.1001). Conventional therapy has concentrated on androgen-dependent activation of the AR through its C-terminal domain.

Other relevant AR antagonists previously reported (see, WO 2010/000066, WO 2011/082487; WO 2011/082488; WO 2012/145330; WO 2015/031984; WO 2016/058080; and WO 2016/058082) that bind to full-length AR and/or truncated AR splice variants that are currently being developed include: AR degraders such as niclosamide (Liu C et al 2014), galeterone (Njar et al 2015; Yu Z at al 2014), and ARV-330/Androgen receptor PROTAC (Neklesa et al 2016 J Clin Oncol 34 suppl 2S; abstr 267); AR DBD inhibitor VPC-14449 (Dalai K et al 2014 J Biol Chem. 289(38):26417-29; Li H et al 2014 J. Med Chem. 57(15):6458-67); antiandrogens apalutamide (Clegg N J et al 2012), ODM-201 (Moilanen A M et al 2015), ODM-204 (Kallio et al J Clin Oncol 2016 vol. 34 no. 2 suppl 230), TAS3681 (Minamiguchi et al 2015 J Clin Oncol 33, suppl 7; abstr 266); and AR NTD inhibitors 3E10-AR441bsAb (Goicochea N L et al 2015), and sintokamide (Sadar et al 2008; Banuelos et al 2016).

The AR-NTD is also a target for drug development (e.g. WO 2000/001813; Myung et al. J. Clin. Invest 2013, 123, 2948), since the NTD contains Activation-Function-1 (AF-1) which is the essential region required for AR transcriptional activity (Jenster et al 1991. Mol Endocrinol. 5, 1396-404). The AR-NTD importantly plays a role in activation of the AR in the absence of androgens (Sadar, M. D. 1999 J. Biol. Chem. 274, 7777-7783; Sadar M D et al 1999 Endocr Relat Cancer. 6, 487-502; Ueda et al 2002 J. Biol. Chem. 277, 7076-7085; Ueda 2002 J. Biol. Chem. 277, 38087-38094; Blaszczyk et al 2004 Clin Cancer Res. 10, 1860-9; Dehm et al 2006 J Biol Chem. 28, 27882-93; Gregory et al 2004 J Biol Chem. 279, 7119-30). The AR-NTD is important in hormonal progression of prostate cancer as shown by application of decoy molecules (Quayle et al 2007, Proc Natl Acad Sci USA. 104,1331-1336).

While the crystal structure has been resolved for the AR C-terminus LBD, this has not been the case for the NTD due to its high flexibility and intrinsic disorder in solution (Reid et al 2002 J. Biol. Chem. 277, 20079-20086) thereby hampering virtual docking drug discovery approaches. Compounds that modulate AR, potentially through interaction with NTD domain, include the bisphenol compounds disclosed in published PCT Nos: WO 2010/000066, WO 2011/082487; WO 2011/082488; WO 2012/145330; WO 2012/139039; WO 2012/145328; WO 2013/028572; WO 2013/028791; WO 2014/179867; WO 2015/031984; WO 2016/058080; WO 2016/058082; WO 2016/112455; WO 2016/141458; WO 2017/177307; WO 2017/210771; and WO 2018/045450, and which are hereby incorporated by reference in their entireties.

Transcriptionally active androgen receptor plays a major role in CRPC in spite of reduced blood levels of androgen (Karantanos, T. et al Oncogene 2013, 32, 5501-5511; Harris, W. P. et al Nature Clinical Practice Urology, 2009, 6, 76-85). AR mechanisms of resistance to ADT include: overexpression of AR (Visakorpi, T. et al Nature Genetics 1995, 9, 401-406; Koivisto, P. et al Scandinavian Journal of Clinical and Laboratory Investigation Supplementum 1996, 226, 57-63); gain-of-function mutations in the AR LBD (Culig Z. et al Molecular Endocrinology 1993, 7, 1541-1550); intratumoral androgen synthesis (Cai, C. et al Cancer Research 2011, 71, 6503-6513); altered expression and function of AR coactivators (Ueda, T. et al The Journal of Biological Chemistry 2002, 277, 38087-38094; Xu J. et al Nature Reviews Cancer 2009, 9, 615-630); aberrant post-translational modifications of AR (Gioeli D. et al Molecular and Cellular Endocrinology 2012, 352, 70-78; van der Steen T. et al International Journal of Molecular Sciences 2013, 14, 14833-14859); and expression of AR splice variants (AR-Vs) which lack the ligand-binding domain (LBD) (Karantanos, T. et al Oncogene 2013, 32, 5501-5511; Andersen R. J. et al Cancer Cell 2010, 17, 535-546; Myung J. K. et al The Journal of Clinical Investigation 2013, 123, 2948-2960; Sun S. et al The Journal of Clinical Investigation 2010, 120, 2715-2730). Anti-androgens such as bicalutamide and enzalutamide target AR LBD, but have no effect on truncated constitutively active AR-Vs such as AR-V7 (Li Y. et al Cancer Research 2013, 73, 483-489). Expression of AR-V7 is associated with resistance to current hormone therapies (Li Y. et al Cancer Research 2013, 73, 483-489; Antonarakis E. S. et al The New England Journal of Medicine 2014, 371, 1028-1038).

While significant advances have been made in this field, there remains a need for improved treatment for AR-mediated disorders including prostate cancer.

DETAILED DESCRIPTION

All publications, patents and patent applications, including any drawings and appendices therein are incorporated by reference in their entirety for all purposes to the same extent as if each individual publication, patent or patent application, drawing, or appendix was specifically and individually indicated to be incorporated by reference in its entirety for all purposes.

Definitions

While the following terms are believed to be well understood by one of ordinary skill in the art, the following definitions are set forth to facilitate explanation of the presently disclosed subject matter.

Throughout the present specification, the terms “about” and/or “approximately” may be used in conjunction with numerical values and/or ranges. The term “about” is understood to mean those values near to a recited value. Furthermore, the phrases “less than about [a value]” or “greater than about [a value]” should be understood in view of the definition of the term “about” provided herein. The terms “about” and “approximately” may be used interchangeably.

Throughout the present specification, numerical ranges are provided for certain quantities. It is to be understood that these ranges comprise all subranges therein. Thus, the range “from 50 to 80” includes all possible ranges therein (e.g., 51-79, 52-78, 53-77, 54-76, 55-75, 60-70, etc.). Furthermore, all values within a given range may be an endpoint for the range encompassed thereby (e.g., the range 50-80 includes the ranges with endpoints such as 55-80, 50-75, etc.).

The term “a” or “an” refers to one or more of that entity; for example, “a androgen receptor modulator” refers to one or more androgen receptor modulators or at least one androgen receptor modulator. As such, the terms “a” (or “an”), “one or more” and “at least one” are used interchangeably herein. In addition, reference to “an inhibitor” by the indefinite article “a” or “an” does not exclude the possibility that more than one of the inhibitors is present, unless the context clearly requires that there is one and only one of the inhibitors.

As used herein, the verb “comprise” as is used in this description and in the claims and its conjugations are used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. The present invention may suitably “comprise”, “consist of”, or “consist essentially of”, the steps, elements, and/or reagents described in the claims.

It is further noted that the claims may be drafted to exclude any optional element. As such, this statement is intended to serve as antecedent basis for use of such exclusive terminology as “solely”, “only” and the like in connection with the recitation of claim elements, or the use of a “negative” limitation.

The term “pharmaceutically acceptable salts” includes both acid and base addition salts. Pharmaceutically acceptable salts include those obtained by reacting the active compound functioning as a base, with an inorganic or organic acid to form a salt, for example, salts of hydrochloric acid, sulfuric acid, phosphoric acid, methanesulfonic acid, camphorsulfonic acid, oxalic acid, maleic acid, succinic acid, citric acid, formic acid, hydrobromic acid, benzoic acid, tartaric acid, fumaric acid, salicylic acid, mandelic acid, carbonic acid, etc. Those skilled in the art will further recognize that acid addition salts may be prepared by reaction of the compounds with the appropriate inorganic or organic acid via any of a number of known methods.

The term “treating” means one or more of relieving, alleviating, delaying, reducing, improving, or managing at least one symptom of a condition in a subject. The term “treating” may also mean one or more of arresting, delaying the onset (i.e., the period prior to clinical manifestation of the condition) or reducing the risk of developing or worsening a condition.

The compounds of the invention, or their pharmaceutically acceptable salts can contain one or more asymmetric centers and can thus give rise to enantiomers, diastereomers, and other stereoisomeric forms that can be defined, in terms of absolute stereochemistry, as (R)- or (S)- or, as (D)- or (L)- for amino acids. The present disclosure is meant to include all such possible isomers, as well as their racemic and optically pure forms whether or not they are specifically depicted herein. Optically active (+) and (−), (R)- and (S)-, or (D)- and (L)-isomers can be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques, for example, chromatography and fractional crystallization. Conventional techniques for the preparation/isolation of individual enantiomers include chiral synthesis from a suitable optically pure precursor or resolution of the racemate (or the racemate of a salt or derivative) using, for example, chiral high pressure liquid chromatography (HPLC). When the compounds described herein contain olefinic double bonds or other centers of geometric asymmetry, and unless specified otherwise, it is intended that the compounds include both E and Z geometric isomers. Likewise, all tautomeric forms are also intended to be included.

A “stereoisomer” refers to a compound made up of the same atoms bonded by the same bonds but having different three-dimensional structures, which are not interchangeable. The present disclosure contemplates various stereoisomers and mixtures thereof and includes “enantiomers”, which refers to two stereoisomers whose molecules are nonsuperimposable mirror images of one another.

A “tautomer” refers to a proton shift from one atom of a molecule to another atom of the same molecule. The present disclosure includes tautomers of any said compounds.

A “prodrug” refers to a derivative of a compound of the present disclosure that will be converted to the compound in vivo. In one embodiment of the present disclosure, a prodrug includes a compound of for example abiraterone having a free hydroxyl group (—OH) that is acetylated (—OCOMe) or acylated at one or more positions.

An “effective amount” means the amount of a formulation according to the invention that, when administered to a patient for treating a state, disorder or condition is sufficient to effect such treatment. The “effective amount” will vary depending on the active ingredient, the state, disorder, or condition to be treated and its severity, and the age, weight, physical condition and responsiveness of the mammal to be treated.

The term “therapeutically effective” applied to dose or amount refers to that quantity of a compound or pharmaceutical formulation that is sufficient to result in a desired clinical benefit after administration to a patient in need thereof.

The term “combination therapy” refers to a first therapy that includes Compound A in conjunction with a second therapy (e.g., therapy, surgery and/or an additional pharmaceutical agent) useful for treating, stabilizing, preventing, and/or delaying the disease or condition.

Administration in “conjunction with” another therapeutically active agent includes administration in the same or different composition(s) and/or combinations, either sequentially, simultaneously, or continuously, through the same or different routes. In some embodiments, the combination therapy optionally includes one or more pharmaceutically acceptable carriers or excipients, non-pharmaceutically active compounds, and/or inert substances.

The terms “pharmaceutical combination,” “therapeutic combination” or “combination” as used herein, refers to a single dosage form comprising at least two therapeutically active agents, or separate dosage forms comprising at least two therapeutically active agents together or separately for use in a combination therapy. For example, one therapeutically active agent may be formulated into one dosage form and the other therapeutically active agent may be formulated into a single or different dosage forms. For example, one therapeutically active agent may be formulated into a solid oral dosage form whereas the second therapeutically active agent may be formulated into a solution dosage form for parenteral administration, including as a kit, or from two kits.

A “fixed dosage form” as used herein means a dosage formulation in which one or more therapeutically active agents are combined in a single dosage formulation.

A “co-packaged form” as used herein means that the therapeutically active agents are taken together, more than one dosage forms wherein the therapeutically active agents are taken together, or more than one dosage forms wherein the therapeutically active agents are taken separately in two or more pharmaceutical compositions, i.e., such as two or more separate tablets, capsules, gel capsules, pellets, etc, but typically the separate compositions are as a single kit.

As used herein, the term “pharmaceutical composition” refers to a formulation comprising at least one therapeutically active agent and a pharmaceutically acceptable excipient or carrier. A non-limiting example of pharmaceutical compositions includes tablets, capsules, gel capsules, syrup, liquid, gel, suspension, solid dispersion, or combinations thereof.

As used herein, the term “dosage form” refers to one or more pharmaceutical compositions which provides a specific amount of a therapeutically active agent, such as a unit dose. In one embodiment, a dosage form can be provided in one or more pharmaceutical compositions. For example, if a subject is to be administered with 200 mg of a therapeutically active agent at a time (unit dose), a dosage form can comprise two tablets each containing 100 mg of the therapeutically active agent, wherein the two tablets are the same pharmaceutical composition.

As used herein, the term “solid dispersion” is a system in a solid state (as opposed to a liquid or gaseous state) comprising at least two components, wherein one component is dispersed more or less evenly throughout the other component or components (homogenous mix). Generally, a solid dispersion formulation of a therapeutically active agent(s) refers to a dispersion mixture of the therapeutically active agent(s) in an inert carrier. Inert carriers can be a crystalline carrier (such as sugars), a polymeric carrier (such as HPMCAS), or a mixture of surfactants and polymers. Typically, a solid dispersion of a therapeutically active agent increases the surface area of the therapeutically active agent and enhances drug solubility and/or dissolution rate.

As used herein, a “subject” can be a human, non-human primate, mammal, rat, mouse, cow, horse, pig, sheep, goat, dog, cat and the like. The subject can be suspected of having or at risk for having a cancer, such as prostate cancer, breast cancer, ovarian cancer, salivary gland carcinoma, or endometrial cancer, or suspected of having or at risk for having acne, hirsutism, alopecia, benign prostatic hyperplasia, ovarian cysts, polycystic ovary disease, precocious puberty, spinal and bulbar muscular atrophy, or age-related macular degeneration. Diagnostic methods for various cancers, such as prostate cancer, breast cancer, ovarian cancer, bladder cancer, pancreatic cancer, hepatocellular cancer, salivary gland carcinoma, or endometrial cancer, and diagnostic methods for acne, hirsutism, alopecia, benign prostatic hyperplasia, ovarian cysts, polycystic ovary disease, precocious puberty, spinal and bulbar muscular atrophy, or age-related macular degeneration and the clinical delineation of cancer, such as prostate cancer, breast cancer, ovarian cancer, bladder cancer, pancreatic cancer, hepatocellular cancer, salivary gland carcinoma, or endometrial cancer, diagnoses and the clinical delineation of acne, hirsutism, alopecia, benign prostatic hyperplasia, ovarian cysts, polycystic ovary disease, precocious puberty, spinal and bulbar muscular atrophy, or age-related macular degeneration are known to those of ordinary skill in the art.

“Mammal” includes humans and both domestic animals such as laboratory animals (e.g., mice, rats, monkeys, dogs, etc.) and household pets (e.g., cats, dogs, swine, cattle, sheep, goats, horses, rabbits), and non-domestic animals such as wildlife and the like.

All weight percentages (i.e., “% by weight” and “wt. %” and w/w) referenced herein, unless otherwise indicated, are measured relative to the total weight of the pharmaceutical composition.

As used herein, “substantially” or “substantial” refers to the complete or nearly complete extent or degree of an action, characteristic, property, state, structure, item, or result. For example, an object that is “substantially” enclosed would mean that the object is either completely enclosed or nearly completely enclosed. The exact allowable degree of deviation from absolute completeness may in some cases depend on the specific context. However, generally speaking, the nearness of completion will be so as to have the same overall result as if absolute and total completion were obtained. The use of “substantially” is equally applicable when used in a negative connotation to refer to the complete or near complete lack of action, characteristic, property, state, structure, item, or result. For example, a composition that is “substantially free of” other active agents would either completely lack other active agents, or so nearly completely lack other active agents that the effect would be the same as if it completely lacked other active agents. In other words, a composition that is “substantially free of” an ingredient or element or another active agent may still contain such an item as long as there is no measurable effect thereof.

The following description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed inventions, or that any publication specifically or implicitly referenced is prior art.

Diluents for solid compositions and/or combinations include, for example, microcrystalline cellulose (e.g., AVICEL), microfine cellulose, lactose, starch, pregelatinized starch, calcium carbonate, calcium sulfate, sugar, dextrates, dextrin, dextrose, dibasic calcium phosphate dihydrate, tribasic calcium phosphate, kaolin, magnesium carbonate, magnesium oxide, maltodextrin, mannitol, polymethacrylates (e.g., EUDRAGIT®), potassium chloride, powdered cellulose, sodium chloride, sorbitol, and talc.

Additional embodiments relate to the pharmaceutical formulations wherein the formulation is selected from the group consisting of a solid, powder, liquid and a gel. In certain embodiments, a pharmaceutical composition of the present invention is a solid (e.g., a powder, tablet, a capsule, granulates, and/or aggregates). In certain of such embodiments, a solid pharmaceutical composition comprising one or more ingredients known in the art, including, but not limited to, starches, sugars, diluents, granulating agents, lubricants, binders, and disintegrating agents.

Solid pharmaceutical compositions that are compacted into a dosage form, such as a tablet, may include excipients whose functions include helping to bind the active ingredient and other excipients together after compression. Binders for solid pharmaceutical compositions and/or combinations include acacia, alginic acid, carbomer (e.g., carbopol), carboxymethylcellulose sodium, dextrin, ethyl cellulose, gelatin, guar gum, gum tragacanth, hydrogenated vegetable oil, hydroxyethyl cellulose, hydroxypropyl cellulose (e.g., KLUCEL), hydroxypropyl methyl cellulose (e.g., METHOCEL), liquid glucose, magnesium aluminum silicate, maltodextrin, methylcellulose, polymethacrylates, povidone (e.g., KOLLIDON, PLASDONE), pregelatinized starch, sodium alginate, and starch.

The dissolution rate of a compacted solid pharmaceutical composition in the patient's stomach may be increased by the addition of a disintegrant to the composition and/or combination. Disintegrants include alginic acid, carboxymethylcellulose calcium, carboxymethylcellulose sodium (e.g., AC-DI-SOL and PRIMELLOSE), colloidal silicon dioxide, croscarmellose sodium, crospovidone (e.g., KOLLIDON and POLYPLASDONE), guar gum, magnesium aluminum silicate, methyl cellulose, microcrystalline cellulose, polacrilin potassium, powdered cellulose, pregelatinized starch, sodium alginate, sodium starch glycolate (e.g., EXPLOTAB), potato starch, and starch.

Glidants can be added to improve the flowability of a non-compacted solid composition and/or combination and to improve the accuracy of dosing. Excipients that may function as glidants include colloidal silicon dioxide, magnesium trisilicate, powdered cellulose, starch, talc, and tribasic calcium phosphate.

When a dosage form such as a tablet is made by the compaction of a powdered composition, the composition is subjected to pressure from a punch and dye. Some excipients and active ingredients have a tendency to adhere to the surfaces of the punch and dye, which can cause the product to have pitting and other surface irregularities. A lubricant can be added to the composition and/or combination to reduce adhesion and ease the release of the product from the dye. Lubricants include magnesium stearate, calcium stearate, glyceryl monostearate, glyceryl palmitostearate, hydrogenated castor oil, hydrogenated vegetable oil, mineral oil, polyethylene glycol, sodium benzoate, sodium lauryl sulfate, sodium stearyl fumarate, stearic acid, talc, and zinc stearate.

Flavoring agents and flavor enhancers make the dosage form more palatable to the patient. Common flavoring agents and flavor enhancers for pharmaceutical products that may be included in the composition and/or combination of the present invention include maltol, vanillin, ethyl vanillin, menthol, citric acid, fumaric acid, ethyl maltol, and tartaric acid.

Solid pharmaceutical compositions can optionally have different types of coating. Coatings can be applied to the entire dosage form (e.g. a tablet) or a component of a dosage form (e.g., core, granules, beads, pellets, microparticles, etc). A coating can be used to improve patient compliance (e.g., taste-masking coating, flavor coating, coating to provide smooth surface for easy swallowing), to improve the stability of the compositions (e.g., protection from light, moisture, gas, acid protection, or to divide different layers or compartments to avoid a drug from interacting with different ingredients in a different layer/compartment), alter release profile of the drug (e.g., enteric coating, pH-dependent polymer coating, etc), or improve cosmetic considerations.

A coating can be a thin film-coating comprising one or more polymers or water soluble materials including but are not limited to, hypromellose, macrogol, hydroxyethylcellulose, sodium carboxymethylcellulose, polyethylene glycol, polyvinyl alcohol, and cellulose acetate phthalate. In addition, film coating can comprise one or more pharmaceutically acceptable excipients, including but not limited to titanium dioxide, ferric oxide, coloring agents, talc, or lecithin.

A coating that modifies release of the active ingredient can comprise a pH-dependent polymer (e.g., enteric polymer) or a pH-independent polymer. A release-modifying coating can comprise one or more polymers selected from methacrylic copolymers, aminoalkyl methacrylate copolymers, methacrylate copolymers, or ammonioalkyl methacrylate copolymers. A release-modifying coating can comprise one or more cationic polymer, anionic polymer, or neutral polymer.

Solid and liquid compositions may also be dyed using any pharmaceutically acceptable colorant to improve their appearance and/or facilitate patient identification of the product and unit dosage level.

In certain embodiments, a pharmaceutical composition of the present invention is a liquid (e.g., a suspension, elixir and/or solution). In certain of such embodiments, a liquid pharmaceutical composition is prepared using ingredients known in the art, including, but not limited to, water, glycols, oils, alcohols, flavoring agents, preservatives, and coloring agents.

Liquid pharmaceutical compositions can be prepared where the solid or amorphous components are dissolved or suspended in a liquid carrier such as water, vegetable oil, alcohol, polyethylene glycol, propylene glycol, or glycerin.

For example, formulations for parenteral administration can contain as common excipients sterile water or saline, polyalkylene glycols such as polyethylene glycol, oils of vegetable origin, hydrogenated naphthalenes and the like. In particular, biocompatible, biodegradable lactide polymer, lactide/glycolide copolymer, or polyoxyethylene-polyoxypropylene copolymers can be useful excipients to control the release of active compounds. Other potentially useful parenteral delivery systems include ethylene-vinyl acetate copolymer particles, osmotic pumps, implantable infusion systems, and liposomes. Formulations for inhalation administration contain as excipients, for example, lactose, or can be aqueous solutions containing, for example, polyoxyethylene-9-auryl ether, glycocholate and deoxycholate, or oily solutions for administration in the form of nasal drops, or as a gel to be applied intranasally. Formulations for parenteral administration can also include glycocholate for buccal administration, methoxysalicylate for rectal administration, or citric acid for vaginal administration.

Liquid pharmaceutical compositions can contain emulsifying agents to disperse uniformly throughout the composition and/or combination an active ingredient or other excipient that is not soluble in the liquid carrier. Emulsifying agents that may be useful in liquid compositions and/or combinations of the present invention include, for example, gelatin, egg yolk, casein, cholesterol, acacia, tragacanth, chondrus, pectin, methyl cellulose, carbomer, cetostearyl alcohol, and cetyl alcohol.

Liquid pharmaceutical compositions can also contain a viscosity enhancing agent to improve the mouth-feel of the product and/or coat the lining of the gastrointestinal tract. Such agents include acacia, alginic acid bentonite, carbomer, carboxymethylcellulose calcium or sodium, cetostearyl alcohol, methyl cellulose, ethylcellulose, gelatin guar gum, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, maltodextrin, polyvinyl alcohol, povidone, propylene carbonate, propylene glycol alginate, sodium alginate, sodium starch glycolate, starch tragacanth, and xanthan gum.

Sweetening agents such as aspartame, lactose, sorbitol, saccharin, sodium saccharin, sucrose, aspartame, fructose, mannitol, and invert sugar may be added to improve the taste.

Preservatives and chelating agents such as alcohol, sodium benzoate, butylated hydroxyl toluene, butylated hydroxyanisole, and ethylenediamine tetraacetic acid may be added at levels safe for ingestion to improve storage stability.

A liquid composition can also contain a buffer such as guconic acid, lactic acid, citric acid or acetic acid, sodium guconate, sodium lactate, sodium citrate, or sodium acetate. Selection of excipients and the amounts used may be readily determined by the formulation scientist based upon experience and consideration of standard procedures and reference works in the field.

In one embodiment, a pharmaceutical composition is prepared for administration by injection (e.g., intravenous, subcutaneous, intramuscular, etc.). In certain of such embodiments, a pharmaceutical composition comprises a carrier and is formulated in aqueous solution, such as water or physiologically compatible buffers such as Hanks's solution, Ringer's solution, or physiological saline buffer. In certain embodiments, other ingredients are included (e.g., ingredients that aid in solubility or serve as preservatives). In certain embodiments, injectable suspensions are prepared using appropriate liquid carriers, suspending agents and the like. Certain pharmaceutical compositions for injection are presented in unit dosage form, e.g., in ampoules or in multi-dose containers. Certain pharmaceutical compositions for injection are suspensions, solutions or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents. Certain solvents suitable for use in pharmaceutical compositions for injection include, but are not limited to, lipophilic solvents and fatty oils, such as sesame oil, synthetic fatty acid esters, such as ethyl oleate or triglycerides, and liposomes. Aqueous injection suspensions may contain substances that increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol, or dextran. Optionally, such suspensions may also contain suitable stabilizers or agents that increase the solubility of the pharmaceutical agents to allow for the preparation of highly concentrated solutions.

The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, such as a solution in 1,3-butane-diol or prepared as a lyophilized powder. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile fixed oils may conventionally be employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid may likewise be used in the preparation of injectables. Formulations for intravenous administration can comprise solutions in sterile isotonic aqueous buffer. Where necessary, the formulations can also include a solubilizing agent and a local anesthetic to ease pain at the site of the injection. Generally, the ingredients are supplied either separately or mixed together in unit dosage form, for example, as a dry lyophilized powder or water free concentrate in a hermetically sealed container such as an ampule or sachet indicating the quantity of active agent. Where the compound is to be administered by infusion, it can be dispensed in a formulation with an infusion bottle containing sterile pharmaceutical grade water, saline or dextrose/water. Where the compound is administered by injection, an ampule of sterile water for injection or saline can be provided so that the ingredients can be mixed prior to administration.

Suitable formulations further include aqueous and non-aqueous sterile injection solutions that can contain antioxidants, buffers, bacteriostats, bactericidal antibiotics and solutes that render the formulation isotonic with the bodily fluids of the intended recipient; and aqueous and non-aqueous sterile suspensions, which can include suspending agents and thickening agents.

In certain embodiments, a pharmaceutical composition of the present invention is formulated as a depot preparation. Certain such depot preparations are typically longer acting than non-depot preparations. In certain embodiments, such preparations are administered by implantation (for example subcutaneously or intramuscularly) or by intramuscular injection. In certain embodiments, depot preparations are prepared using suitable polymeric or hydrophobic materials (for example an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt.

In certain embodiments, a pharmaceutical composition of the present invention comprises a delivery system. Examples of delivery systems include, but are not limited to, liposomes and emulsions. Certain delivery systems are useful for preparing certain pharmaceutical compositions including those comprising hydrophobic compounds. In certain embodiments, certain organic solvents such as dimethylsulfoxide are used.

In certain embodiments, a pharmaceutical composition of the present invention comprises a co-solvent system. Certain of such co-solvent systems comprise, for example, benzyl alcohol, a nonpolar surfactant, a water-miscible organic polymer, and an aqueous phase. In certain embodiments, such co-solvent systems are used for hydrophobic compounds. A non-limiting example of such a co-solvent system is the VPD co-solvent system, which is a solution of absolute ethanol comprising 3% w/v benzyl alcohol, 8% w/v of the nonpolar surfactant Polysorbate 80 and 65% w/v polyethylene glycol 300. The proportions of such co-solvent systems may be varied considerably without significantly altering their solubility and toxicity characteristics. Furthermore, the identity of co-solvent components may be varied: for example, other surfactants may be used instead of Polysorbate 80; the fraction size of polyethylene glycol may be varied; other biocompatible polymers may replace polyethylene glycol, e.g., polyvinyl pyrrolidone; and other sugars or polysaccharides may substitute for dextrose.

In certain embodiments, a pharmaceutical composition of the present invention comprises a sustained-release system. A non-limiting example of such a sustained-release system is a semi-permeable matrix of solid hydrophobic polymers. In certain embodiments, sustained-release systems may, depending on their chemical nature, release pharmaceutical agents over a period of hours, days, weeks or months.

In certain embodiments, a pharmaceutical composition of the present disclosure is prepared for oral administration. In certain of such embodiments, a pharmaceutical composition is formulated by combining one or more agents and pharmaceutically acceptable carriers. Suitable excipients include, but are not limited to, fillers, such as sugars, including lactose, sucrose, mannitol, or sorbitol; cellulose preparations such as, for example, maize starch, wheat starch, rice starch, potato starch, gelatin, gum tragacanth, methyl cellulose, hydroxypropylmethyl-cellulose, sodium carboxymethylcellulose, and/or polyvinylpyrrolidone (PVP). In certain embodiments, such a mixture is optionally ground and auxiliaries are optionally added. In certain embodiments, pharmaceutical compositions are formed to obtain tablets or dragee cores. In certain embodiments, disintegrating agents (e.g., cross-linked polyvinyl pyrrolidone, agar, or alginic acid or a salt thereof, such as sodium alginate) are added.

In certain embodiments, dragee cores are provided with coatings. In certain such embodiments, concentrated sugar solutions may be used, which may optionally contain gum arabic, talc, polyvinyl pyrrolidone, carbopol gel, polyethylene glycol, and/or titanium dioxide, lacquer solutions, and suitable organic solvents or solvent mixtures. Dyestuffs or pigments may be added to tablets or dragee coatings.

In certain embodiments, pharmaceutical compositions for oral administration are push-fit capsules made of gelatin. Certain of such push-fit capsules comprise one or more pharmaceutical agents of the present invention in admixture with one or more filler such as lactose, binders such as starches, and/or lubricants such as talc or magnesium stearate and, optionally, stabilizers. In certain embodiments, pharmaceutical compositions for oral administration are soft, sealed capsules made of gelatin and a plasticizer, such as glycerol or sorbitol. In certain soft capsules, one or more pharmaceutical agents of the present invention are be dissolved or suspended in suitable liquids, such as fatty oils, liquid paraffin, or liquid polyethylene glycols. In addition, stabilizers may be added.

In certain embodiments, pharmaceutical compositions are prepared for buccal administration. Certain of such pharmaceutical compositions are tablets or lozenges formulated in conventional manner.

In certain embodiments, a pharmaceutical composition is prepared for transmucosal administration. In certain of such embodiments penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art.

In certain embodiments, a pharmaceutical composition is prepared for administration by inhalation. Certain of such pharmaceutical compositions for inhalation are prepared in the form of an aerosol spray in a pressurized pack or a nebulizer. Certain of such pharmaceutical compositions comprise a propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide or other suitable gas. In certain embodiments using a pressurized aerosol, the dosage unit may be determined with a valve that delivers a metered amount. In certain embodiments, capsules and cartridges for use in an inhaler or insufflator may be formulated. Certain of such formulations comprise a powder mixture of a pharmaceutical agent of the invention and a suitable powder base such as lactose or starch.

In other embodiments the compound of the present disclosure are administered by the intravenous route. In further embodiments, the parenteral administration may be provided in a bolus or by infusion.

In certain embodiments, a pharmaceutical composition is prepared for rectal administration, such as a suppository or retention enema. Certain of such pharmaceutical compositions comprise known ingredients, such as cocoa butter and/or other glycerides.

In certain embodiments, a pharmaceutical composition is prepared for topical administration. Certain of such pharmaceutical compositions comprise bland moisturizing bases, such as ointments or creams. Exemplary suitable ointment bases include, but are not limited to, petrolatum, petrolatum plus volatile silicones, and lanolin and water in oil emulsions. Exemplary suitable cream bases include, but are not limited to, cold cream and hydrophilic ointment.

In certain embodiments, the therapeutically effective amount is sufficient to prevent, alleviate or ameliorate symptoms of a disease or to prolong the survival of the subject being treated. Determination of a therapeutically effective amount is well within the capability of those skilled in the art.

In certain embodiments, one or more therapeutically active agents, or a pharmaceutically acceptable salt or solvate thereof are formulated as a prodrug. In certain embodiments, upon in vivo administration, a prodrug is chemically converted to the biologically, pharmaceutically or therapeutically more active form. In certain embodiments, prodrugs are useful because they are easier to administer than the corresponding active form. For example, in certain instances, a prodrug may be more bioavailable (e.g., through oral administration) than is the corresponding active form. In certain instances, a prodrug may have improved solubility compared to the corresponding active form. In certain embodiments, prodrugs are less water soluble than the corresponding active form. In certain instances, such prodrugs possess superior transmittal across cell membranes, where water solubility is detrimental to mobility. In certain embodiments, a prodrug is an ester. In certain such embodiments, the ester is metabolically hydrolyzed to carboxylic acid upon administration. In certain instances, the carboxylic acid containing compound is the corresponding active form. In certain embodiments, a prodrug comprises a short peptide (polyaminoacid) bound to an acid group. In certain of such embodiments, the peptide is cleaved upon administration to form the corresponding active form.

In certain embodiments, a prodrug is produced by modifying a pharmaceutically active compound such that the active compound will be regenerated upon in vivo administration. The prodrug can be designed to alter the metabolic stability or the transport characteristics of a drug, to mask side effects or toxicity, to improve the flavor of a drug or to alter other characteristics or properties of a drug. By virtue of knowledge of pharmacodynamic processes and drug metabolism in vivo, those of skill in this art, once a pharmaceutically active compound is known, can design prodrugs of the compound (see, e.g., Nogrady (1985) Medicinal Chemistry A Biochemical Approach, Oxford University Press, New York, pages 388-392).

In various aspects, the androgen receptor modulators in the pharmaceutical composition or combination as disclosed herein can be administered at about 0.001 mg/kg to about 100 mg/kg body weight (e.g., about 0.01 mg/kg to about 10 mg/kg or about 0.1 mg/kg to about 5 mg/kg).

The concentration of a disclosed compound in a pharmaceutically acceptable mixture will vary depending on several factors, including the dosage of the compound to be administered, the pharmacokinetic characteristics of the compound(s) employed, and the route of administration. The agent may be administered in a single dose or in repeat doses. The dosage regimen utilizing the compounds of the present invention is selected in accordance with a variety of factors including type, species, age, weight, sex and medical condition of the patient; the severity of the condition to be treated; the route of administration; the renal and hepatic function of the patient; and the particular compound or salt thereof employed. Treatments may be administered daily or more frequently depending upon a number of factors, including the overall health of a patient, and the formulation and route of administration of the selected compound(s). An ordinarily skilled physician or veterinarian can readily determine and prescribe the effective amount of the drug required to prevent, counter or arrest the progress of the condition.

The compounds or pharmaceutical compositions of the present disclosure may be manufactured and/or administered in single or multiple unit dose forms.

Having now generally described the invention, the same will be more readily understood through reference to the following examples, which are provided by way of illustration and are not intended to be limiting of the present invention.

Biological Assays
Example 2: Activity of Exemplary Compounds in Cellular Assays

LNCaP cells were transiently transfected with the PSA (6.1 kb)-luciferase reporter for 24 h, and then treated with indicated concentration of representative compounds with synthetic androgen, R1881 (1 nM) for 24 h. After 24 h of incubation with R1881, the cells were harvested, and relative luciferase activities were determined. To determine the IC₅₀, treatments were normalized to the maximum activity with androgen-induction (in the absence of test compounds, vehicle only) (Table 1).

Luciferase Assay: Lysates were thawed on ice then collected into V-bottom 96-well tissue culture plates. Lysates were centrifuged at 4° C. for 5 minutes at 4000 rpm. To measure luminescence of LNCaP cell lysates the Firefly Luciferase Assay System (Promega) was employed, according to manufacturer's protocol.

Statistical analyses were performed using GraphPad Prism (Version 6.01 for Windows; La Jolla, Calif., USA). Comparisons between treatment and control groups were compared using Two-Way ANOVA with post-hoc Dunnett's and Tukey's tests. Differences were considered statistically significant at P values less than 0.05. Densitometric quantification of relative AR levels was determined by Image.

Example 3. In Vivo Pharmacokinetic Properties

The purpose of this study is to determine the pharmacokinetics of the tested compounds in plasma, following oral gavage administration (PO) to male CD-1 mice.

Animal Husbandry: Animals were group housed during acclimation and the study. The animal room environment were controlled (target conditions: temperature 18 to 26° C., relative humidity 30 to 70%, 12 hours artificial light and 12 hours dark). Temperature and relative humidity were monitored daily. Animals were fasted at least 12 hours prior to the administration. All animals had access to Certified Rodent Diet ad libitum 4 hours post dosing.

Dose Formulation: prepared 85-100 μL of a stock solution of representative compounds of the disclosure in DMSO at 50 mM; 1.5% v/v of Tween 80 were added and mixed gently; 95.5% v/v saline was added gently to the organic phase. The solution was mixed slowly by reverse pipetting to get a clear solution.

Dose Administration: the dose formulations were administered via oral gavage per facility SOPs. The dose volume were determined by the animals' body weight collected on the morning of dosing day

Sample Collection: blood collection (about 0.05 mL per time point) was performed from saphenous vein of each animal into polypropylene tubes at each timepoints (0, 0.25, 0.5, 1, 2, 4, 8, 12, and 24 hr). All blood samples were transferred into pre-chilled tubes containing 2 μL of K2-EDTA (0.5M) and placed on wet ice until centrifugation. Each collected blood sample was in the wet-ice before centrifugation. Each collected blood was under centrifugation for 15 minutes at 4° C. and 3000 g for plasma collection. Plasma samples were stored in polypropylene tubes, quickly frozen over dry ice and kept at −70±10° C. until LC/MS/MS analysis.

Bioanalytical analysis: A LC-MS/MS method for the quantitative determination of tested compound in biological matrix were developed under non-GLP compliance. A calibration curve with at least 7 non-zero calibration standards were applied for the method including LLOQ.

Plasma concentration versus time data were analyzed by non-compartmental approaches using the Phoenix WinNonlin 6.3 software program. Cl, Vdss, C0, Cmax, Tmax, T½, AUC(0-t), AUC(0-inf), MRT(0-t), MRT(0-inf), % F (oral availability) and graphs of plasma concentration versus time profile were reported.

Example 4. In Vivo Activity of Compound a in VCaP Xenografts Model

Tumor growth was measured in male SCID Beige mice bearing VCaP tumors. Castration was performed when tumors reached ˜100 mm³and dosing (as indicated) of enzalutamide, Compound A, or combination of enzalutamide and Compound A started 2 weeks after castration (FIGS. 1A-1C). Individual tumor volume change from baseline measured on day 17 of the experiment (FIGS. 2A-2B). Serum prostate-specific antigen (PSA) was measured in mice at the end of each treatment (FIG. 3). Body weight of the mice were captured biweekly in the animals and normalized to baseline (FIG. 4). Data demonstrated in FIGS. 1-4 shows that Compound A exhibits excellent anti-tumor response as a monotherapy or in combination with enzalutamide.

Example 5. Inhibition of Androgen Responsive Genes in LNCaP Cells

Relative mRNA expression in LNCaP was measured to assess dose-dependent response of Compound A alone or with enzalutamide (Enza), apalutamide (Apa), or darolutamide (Daro) in androgen responsive genes. FIGS. 5A and 5B show log-ratio of gene expression values in LNCaP cells treated with enzalutamide compared to synthetic androgen (R1881) and LNCaP cells treated with Compound A compared to R1881, respectively.

Compound A demonstrated dose-dependent response in the androgen response genes FKBP5, TMPRSS2, KLK2, KLK3, and NKX3.1 (FIG. 6A). The combination of enzalutamide and Compound A exhibited inhibition of the tested androgen responsive genes.

The number of genes significantly down-regulated with Fold changes >4 is shown in FIG. 6B. Top ten down-regulated genes with Enza/Compound A 5 μM/5 μM combination is shown in FIG. 6C. Top twenty down-regulated genes with Enza/Compound A 5 μM/5 μM combination is shown in Table 4. FIGS. 5A-5B and Table 4 demonstrate that Compound A can modulate androgen receptor0 full-length driven genes similar to enzalutamide in LNCaP.

Apalutamide (Apa) or darolutamide (Daro) with or without Compound A was also assessed for gene expression in LNCaP cells. The number of genes significantly down regulated with Fold changes >4 is shown in FIG. 7A. Top ten down regulated genes with Daro/Compound A 5 μM/10 μM combination is shown in FIG. 7B. Darolutamide is not very active in LNCaP.

Data shown in FIGS. 6A-6C and 7A-7B and Table 4 were generated using NanoString Androgen Receptor/Prostate Cancer gene panel.

Example 6. Inhibition of Androgen Responsive Genes in LNCaP95 Cells

Relative mRNA expression in LNCaP95 (+R1881) was measured to assess response to Compound A alone or with enzalutamide (Enza). FIGS. 8A and 8B show log-ratio of gene expression values in LNCaP95 (+R1881) cells treated with enzalutamide compared to synthetic androgen (R1881) and LNCaP95 (+R1881) cells treated with Compound A compared to R1881, respectively.

Relative mRNA expression in LNCaP95 (+R1881) was measured for Canonical AR target genes (FIG. 9A) and AR V7-activated genes (FIG. 9B). FIGS. 8A-8B and 9A-9B demonstrates that Compound A can modulate AR full-length and AR V7 driven genes. Table 5 shows top ten down-regulated genes with log 2 Fold change.

Example 7: Inhibition of Androgen Responsive Genes in VCaP Cells

Relative mRNA expression in VCaP was measured to assess response of Compound A, enzalutamide (Enza), apalutamide (Apa), or darolutamide (Daro) alone or Compound A in combination with Enza, Apa, or Daro, in androgen responsive genes. FIG. 10 shows a heatmap from RNAseq analysis showing normalized expression of top 50 up- or down-regulated genes in response to R1881 stimulation (FC>2, padj<0.01). FIG. 10 demonstrates that Compound A at 10 μM can synergize with Enza, Apa, and Daro (collectively, “′lutamides”) and induces deeper androgen responsive gene expression in VCaP cells.

Further, the activity of Compound A at 10 μM in combination with the ‘lutamides against canonical AR dependent genes showed superior inhibition of responsive genes as shown in FIGS. 11A and 11B.
