     BACKGROUND OF THE INVENTION 
     Breast cancer is a disease that kills over 45,000 women each year in the United States alone. Over 180,000 new cases of breast cancer are diagnosed annually, and it is estimated that one in eight women will develop breast cancer. These numbers indicate that breast cancer is one of the most dangerous diseases facing women today. Cancer research has been unable to determine the cause of breast cancer, and has not found a suitable method of therapy or prevention. 
     The standard of care currently includes screening the tumor for the expression levels of the hormone receptors, estrogen receptor (ER) and progesterone receptor (PR), and the human epidermal growth factor receptor 2 (HER2) kinase. Currently, a woman diagnosed with breast cancer may be treated preliminarily with surgery, chemotherapy (optional in some cases), and radiation before targeted therapy is initiated. Hormone receptor-positive breast cancers are susceptible to hormone therapies with selective estrogen receptor modulators or SERMs (e.g., tamoxifen, toremifene), aromatase inhibitors (e.g., anastrozole), or selective estrogen receptor degraders or SERDs (e.g., fulvestrant). Hormone therapies such as aromatase inhibitors (AI) block production of estrogens in the body (typically used in post-menopausal women), whereas SERMs and SERDs block the proliferative action of estrogens on the breast cancer cells. Hormone receptor-positive and HER2-negative patients that have failed initial hormone therapy are often treated with an inhibitor of cyclin-dependent kinase (CDK) types 4 and 6 (CDK4/6 inhibitor) palbociclib (Ibrance) in combination with either letrozole or fulvestrant. HER2-positive breast cancers are susceptible to HER2 kinase inhibitors (e.g., trastuzumab and lapatinib) and are generally used in metastatic disease. Anti-angiogenic therapy (bevacizumab) is also approved in metastatic disease. Despite these multiple tiers of targeted treatments, patients often have or develop refractory forms of breast cancer. Examples of refractory breast cancer include primary tumors which are triple-negative (lacking ER, PR, HER2), hormone resistant (SERM-, SERD-, or AI-resistant), or kinase inhibitor resistant, or metastatic breast cancer tumors. Once the targeted therapies fail or tumors metastasize, radiation and high dose chemotherapy are required to ablate the refractory breast cancer tumors. Current chemotherapies available for the treatment of refractory breast cancer include anthracyclines, taxanes, and epothilones, which are toxic, dangerous, costly, and often are ineffective, especially in the treatment of metastatic disease. 
     Abundant clinical evidence suggests that androgens normally inhibit breast growth. For instance, women with androgen deficits have an increased risk for developing breast cancer. Androgen signaling plays a crucial role in breast homeostasis, negating the proliferative effects of estrogen signaling in the breast. However, when androgens transform into estrogens (aromatase pathway), they increase cell proliferation and mammary carcinogenesis risk. Historically, the steroidal androgen receptor agonists testosterone, fluoxymesterone, and calusterone were used in advanced breast cancer. These agents suffered from side effects such as excessive virilization, cross-reactivity with the estrogen receptor, and aromatization to estrogens. The use of steroidal androgens in advanced breast cancer pre-dates the screening of breast cancers for hormone and kinase receptors. Recently, it was found that the AR is expressed in 50-90% of breast tumors, providing a mechanism to use androgens as targeted therapy for AR-positive breast cancers. 
     Although the majority of breast cancers are considered hormone receptor-positive (ER, PR, or HER2), 15-20% of women diagnosed with breast cancer will have Triple Negative Breast Cancer (TNBC) which is characterized by a lack of expression of ER, PR, or HER2. TNBC occurs more frequently in younger patients (&lt;50 years of age) and generally shows a more aggressive behavior. For those patients with advanced TNBC, standard palliative treatment options are limited to cytotoxic chemotherapy. However, even after initial response to chemotherapy, the duration of the response may be short and there is a higher likelihood of visceral metastases, rapidly progressive disease, and inferior survival compared to hormone positive breast cancer. Therefore, research is focused on identifying therapeutic targets in TNBC. One such target is the androgen receptor (AR). The AR is the most highly expressed steroid receptor in breast cancer with up to 95% of ER-positive breast cancers expressing AR (see Example 9 infra). In TNBC, up to 30% of cancers may express AR. Historically, AR has been considered anti-proliferative and beneficial in hormone positive breast cancers. In TNBC, data demonstrates that the presence of AR and androgen synthesizing enzymes is associated with lower proliferation, lower tumor grade, better overall survival, and more favorable clinical outcomes as compared to those patients with TNBC not expressing AR. Evidence also suggests that the AR target gene prostate specific antigen (PSA) is a favorable prognostic marker in breast cancer. Based on these findings, research is focused on AR as a potential therapeutic target. 
     Selective androgen receptor modulators (SARMs) are compounds which demonstrate AR-mediated tissue selective activity. Unlike their steroidal precursors, SARMs are non-aromatizable, generally demonstrate no activity at other steroidal receptors including ER and PR, and are non-virilizing. Further, SARMs may be beneficial in refractory breast cancer patients due to their hypermyoanabolic effects that should improve their tolerance of high-dose chemotherapy. 
     New innovative approaches are urgently needed at both the basic science and clinical levels to develop compounds which are useful for: a) treating a subject suffering from breast cancer; b) treating a subject suffering from metastatic breast cancer; c) treating a subject suffering from refractory breast cancer; d) treating a subject suffering from AR-positive breast cancer; e) treating a subject suffering from AR-positive refractory breast cancer; f) treating a subject suffering from AR-positive metastatic breast cancer; g) treating a subject suffering from AR-positive and ER-positive breast cancer; and/or h) treating, preventing, suppressing or inhibiting metastasis in a subject suffering from breast cancer.

         FIG. 7  shows DHT alters the morphology of MDA-MB-231 cells. 
         FIG. 8  illustrates the effect of Formula VIII on steroid receptor transactivation (agonist mode). 
         FIG. 9  depicts a dose response curve of PR activity (antagonist mode) for compound of Formula VIII, Formula IX, R-enantiomer of Formula IX and RU486. The closed circles (●) correspond to Formula VIII data points (IC 50 =17.05 nM); open circles (∘) correspond to Formula IX (IC 50 =162.9 nM); closed triangles (▾) correspond to R-enantiomer of Formula IX (IC 50=1689  nM); and open triangles (Δ) correspond to RU486 (IC 50 =0.048 nM). 
         FIG. 10A - FIG. 10B  demonstrate that SARM (Formula VIII) inhibits MDA-MB-231-AR tumor growth. Body weight ( 10 A) and tumor size ( 10 B) were measured for 35 days in intact female nude mice having 150-200 mm 3  tumors from MDA-MB-231-AR triple negative breast cancer cells and then orally administered vehicle (∘) or 30 mg/kg of Formula VIII (●). 
         FIG. 11  demonstrates that SARM (Formula VIII) inhibits MDA-MB-231-AR tumor growth. Tumor size in mm 3  (A) and % change in tumor size (B), as well as tumor weight (C) were measured after 35 days in intact female nude mice having 150-200 mm 3  tumors from MDA-MB-231-AR triple negative breast cancer cells and then receiving oral administration of vehicle or 30 mg/kg of Formula VIII. 
         FIG. 12  demonstrates the morphology of MDA-MB-231 breast cancer cells stably transfected with AR (MDA-MB-231-AR cells). The results indicate that AR agonists, DHT, Formula IX, and Formula VIII altered the morphology into a more anchored phenotype compared to vehicle, bicalutamide or an inactive isomer of Formula IX. This may be indicative of a less metastatic breast cancer phenotype. 
         FIG. 13A - FIG. 13C  demonstrate binding and transactivation of the indicated ligands to HEK-293 ( 13 A) or MDA-MB-231 ( 13 B &amp;  13 C) cells. DHT, Formula IX and Formula VIII are agonists of AR in breast cancer cells. (Example 16) 
         FIG. 14  demonstrates anti-proliferative activity of DHT and SARMs in MDA-MB-231 breast cancer cells stably transfected with AR. MDA-MB-231 cells stably transfected with AR using lentivirus were treated with the indicated ligands for 6 days and the number of cells counted using Coulter counter. DHT and SARMs, but not the AR antagonist, bicalutamide, inhibited the proliferation of MDA-MB-231 triple negative breast cancer cells stably transfected with AR. 
         FIG. 15  presents microarray results showing that activated AR (AR activated by compound of Formula VIII) suppressed the expression of more genes than it induced in MDA-MB-231-AR xenograft breast cancer cells. 
         FIG. 16  depicts validation of microarray results. 
         FIG. 17  illustrates that Formula VIII inhibited the growth of MCF-7-AR triple positive xenograft. 
         FIG. 18  presents inhibition of uterus weight gain in estrogen supplemented animals treated with Formula VIII, demonstrating the ability of a SARM to counteract estrogenic stimuli in vivo. 
         FIG. 19  shows that the AR expression pattern in response to an AR-agonist (Formula VIII) is similar to that observed in prostate cancer cells. 
         FIG. 20  depicts validation of microarray results. 
         FIG. 21  demonstrates up-regulation of JNK phosphorylation in MCF7-AR tumors using Formula VIII. 
         FIG. 22  shows inhibition of triple negative breast cancer (TNBC) growth using Formulae VIII and IX. Formula VIII and Formula IX demonstrated ˜85% TGI at all doses tried (5, 10 mg per kg for Formula VIII; 5, 10, 30 mg per kg for Formula IX) in the TNBC model using MDA-MB-231-AR cells in nude mice. 
         FIG. 23  demonstrates inhibition of triple negative breast cancer using Formulae VIII and IX. The tumor weights were likewise reduced for all doses of Formula VIII and Formula IX. Spleen enlargement (680 mg vs. 200-300 mg for normal mice) was seen only in vehicle treated mice, possibly indicative of prevention by the SARMs of tumor metastasis to the spleen. 
         FIG. 24  shows increased body weight by the SARMs at all doses of Formula VIII and Formula IX, indicative of healthy growth and a lack of toxicity. By comparison, the vehicle treated animals did not grow as robustly. 
         FIG. 25A  to  FIG. 25E  depict antagonism by SARM regarding the ability of estradiol to activate ER target genes in MCF-7-AR cells.  FIG. 25B  and  FIG. 25D  show that adding AR (as opposed to Green Fluorescent Protein (GFP) as seen in  FIGS. 25A and 25C ) to MCF-7-AR cells increases the effects of estradiol (when unopposed) on the ER target genes PR and PS2, respectively. Adding AR to MCF-7-AR cells suppressed the activation of these ER targets in the presence of SARM alone or SARM+ estradiol (E2) as compared to GFP transfected cells (i.e. no AR;  FIG. 25A  and  FIG. 25C ).  FIG. 25E  shows that AR target genes are enhanced by SARM even in the presence of estradiol. 
         FIG. 26A  and  FIG. 26B  depict immunohistochemistry of two regions of the same BR-0001 tumor, a triple negative breast cancer (TNBC). They show that AR expression is consistent throughout this formalin-fixed, paraffin-embedded (FFPE) tissue stained with AR antibody (AR N20 from SCBT).  FIG. 26C  depicts immunohistochemistry staining of an AR-negative TNBC FFPE tumor as a negative control. 
         FIG. 27A - FIG. 27C  depict BR-0001 tumor xenograft growth inhibition by Formula IX compared to enzalutamide (Enza) or vehicle in terms of breast cancer tumor volume ( FIG. 27A  and  FIG. 27B ) and weight ( FIG. 27C ) with time. Experiments 1 and 2 were duplicate experiments run at different times with n=5 and n=10 animals, respectively.  FIG. 27A  provides results for Experiment 1,  FIG. 27B  provides results for Experiment 2 and  FIG. 27C  provides results for Experiment 2. BR-0001 TNBC fragments of 1 mm 3  (approximately) were implanted subcutaneously in NOD scid gamma (NSG) mice. Once the tumors reach 100-200 mm 3 , the animals were randomized and treated with vehicle, 10 mg/kg/day Formula IX or enzalutamide orally. Tumor volume was measured thrice weekly. Animals were sacrificed and tumors were weighed. 
         FIG. 28A - FIG. 28B  depict immunohistochemistry of BR-0001 tumors from animals treated with vehicle or Formula IX and stained for Ki-67. Ki-67 was reduced in tumors of animals treated with Formula IX. Quantification of Ki-67 indicated an approximately 50% reduction in Ki-67 staining in 2 weeks of treatment. Tumors from experiment 2 were fixed in formalin and paraffin embedded. Slides were cut and stained with Ki-67 antibody ( FIG. 28A ), Ki-67 staining was reduced in tumors of animals treated with Formula IX. Ki-67 positive cells in each slide (total of 200 cells per view) were counted and represented as % stained cells ( FIG. 28B ). As a reference, inset into the graphics are bars which are 200 microns (μm) in length. 
         FIG. 29  depicts Z-scores of 50 genes (PAM50) used to identify BR-0001. PAM50 is a set of 50 genes used to classify breast cancers. PAM50 gene expression data indicated that the BR-0001 tumor belonged to basal-like breast cancer (BLBC) subtype of TNBC. The expression (Z-score) of 50 genes required to classify the breast cancer is given here. 
         FIG. 30A  and  FIG. 30B  depict gene expression data which is compared to the genes published (Pietenpol group) as useful to classify the Basal-Like Breast Cancer (BLBC) into subclassification. Sub-classification indicated that BR-0001 belonged to luminal androgen receptor (LAR) and mesenchymal stem-like (MSL) subtypes.

     Osteoporosis is a systemic skeletal disease, characterized by low bone mass and deterioration of bone tissue, with a consequent increase in bone fragility and susceptibility to fracture. In the U.S., the condition affects more than 25 million people and causes more than 1.3 million fractures each year, including 500,000 spine, 250,000 hip and 240,000 wrist fractures annually. Hip fractures are the most serious consequence of osteoporosis, with 5-20% of patients dying within one year, and over 50% of survivors being incapacitated. The elderly are at greatest risk of osteoporosis, and the problem is therefore predicted to increase significantly with the aging of the population. Worldwide fracture incidence is forecasted to increase three-fold over the next 60 years, and one study estimated that there will be 4.5 million hip fractures worldwide in 2050. 
     Women are at greater risk of osteoporosis than men. Women experience a sharp acceleration of bone loss during the five years following menopause. Other factors that increase the risk include smoking, alcohol abuse, a sedentary lifestyle and low calcium intake. However, osteoporosis also occurs frequently in males. It is well established that the bone mineral density of males decreases with age. Decreased amounts of bone mineral content and density correlates with decreased bone strength, and predisposes to fracture. The molecular mechanisms underlying the pleiotropic effects of sex-hormones in non-reproductive tissues are only beginning to be understood, but it is clear that physiologic concentrations of androgens and estrogens play an important role in maintaining bone homeostasis throughout the life-cycle. Consequently, when androgen or estrogen deprivation occurs there is a resultant increase in the rate of bone remodeling that tilts the balance of resorption and formation to the favor of resorption that contributes to the overall loss of bone mass. In males, the natural decline in sex-hormones at maturity (direct decline in androgens as well as lower levels of estrogens derived from peripheral aromatization of androgens) is associated with the frailty of bones. This effect is also observed in males who have been castrated. 
     In one embodiment, this invention provides for the use of a compound as herein described, or its prodrug, analog, isomer, metabolite, derivative, pharmaceutically acceptable salt, pharmaceutical product, polymorph, crystal, impurity, N-oxide, hydrate or any combination thereof, for: a) treating a bone related disorder; b) preventing a bone related disorder; c) suppressing a bone related disorder; d) inhibiting a bone related disorder; e) increasing a strength of a bone of a subject; f) increasing a bone mass in a subject; g) use for osteoclastogenesis inhibition. 
     In one embodiment, this invention provides for the use of a compound as herein described, or its prodrug, analog, isomer, metabolite, derivative, pharmaceutically acceptable salt, pharmaceutical product, polymorph, crystal, impurity, N-oxide, hydrate or any combination thereof, for: a) accelerating bone repair; b) treating bone disorders; c) treating bone density loss; d) treating low bone mineral density (BMD); e) treating reduced bone mass; f) treating metabolic bone disease; g) promoting bone growth or regrowth; h) promoting bone restoration; i) promoting bone fracture repair; j) promoting bone remodeling; k) treating bone damage following reconstructive surgery including of the face, hip, or joints; l) enhancing of bone strength and function; m) increasing cortical bone mass; and/or n) increasing trabecular connectivity. 
     In one embodiment, the bone related disorder is a genetic disorder, or in another embodiment, is induced as a result of a treatment regimen for a given disease. For example, and in one embodiment, the compounds as herein described are useful in treating a bone-related disorder that arises as a result of cancer metastasis to bone, or in another embodiment, as a result of androgen-deprivation therapy, for example, given in response to prostate carcinogenesis in the subject. 
     As used herein, “Estrogen-deprivation therapy” may refer to therapy which is given in response to breast cancer in a subject. Known treatments include treatment with SERMs, SERDs, or aromatase inhibitors (AI). For example, and in one embodiment, the compounds as herein described are useful in treating a bone-related disorder that arises as a result of cancer metastasis to bone, or in another embodiment, as a result of estrogen-deprivation therapy, for example, given in response to breast cancer in the subject. Menopause can also be induced using GnRH agonists such as gosarelin (Zoladex) which maintains endogeneous estrogens at low levels via inhibition of the hypothalamus-pituitary-gonadal axis. 
     In one embodiment, the bone-related disorder is a loss of bone mineral density (BMD). In another embodiment, the bone-related disorder is osteoporosis. In another embodiment, the bone-related disorder is osteopenia. In another embodiment, the bone-related disorder is increased bone resorption. In another embodiment, the bone-related disorder is bone fracture. In another embodiment, the bone-related disorder is bone frailty. In another embodiment, the bone-related disorder is any combination of osteoporosis, osteopenia, increased bone resorption, bone fracture, bone frailty and loss of BMD. Each disorder represents a separate embodiment of the present invention. 
     “Osteoporosis” refers, in one embodiment, to a thinning of the bones with reduction in bone mass due to depletion of calcium and bone protein. In another embodiment, osteoporosis is a systemic skeletal disease, characterized by low bone mass and deterioration of bone tissue, with a consequent increase in bone fragility and susceptibility to fracture. In osteoporotic patients, bone strength is abnormal, in one embodiment, with a resulting increase in the risk of fracture. In another embodiment, osteoporosis depletes both the calcium and the protein collagen normally found in the bone, in one embodiment, resulting in either abnormal bone quality or decreased bone density. In another embodiment, bones that are affected by osteoporosis can fracture with only a minor fall or injury that normally would not cause a bone fracture. The fracture can be, in one embodiment, either in the form of cracking (as in a hip fracture) or collapsing (as in a compression fracture of the spine). The spine, hips, and wrists are common areas of osteoporosis-induced bone fractures, although fractures can also occur in other skeletal areas. Unchecked osteoporosis can lead, in another embodiment, to changes in posture, physical abnormality, and decreased mobility. 
     In one embodiment, the osteoporosis results from androgen deprivation. In another embodiment, the osteoporosis follows androgen deprivation. In another embodiment, the osteoporosis results from estrogen-deprivation therapy. In another embodiment, the osteoporosis follows estrogen-deprivation therapy. In another embodiment, the osteoporosis is primary osteoporosis. In another embodiment, the osteoporosis is secondary osteoporosis. In another embodiment, the osteoporosis is postmenopausal osteoporosis. In another embodiment, the osteoporosis is juvenile osteoporosis. In another embodiment, the osteoporosis is idiopathic osteoporosis. In another embodiment, the osteoporosis is senile osteoporosis. 
     In another embodiment, the primary osteoporosis is type I primary osteoporosis. In another embodiment, the primary osteoporosis is type II primary osteoporosis. Each type of osteoporosis represents a separate embodiment of the present invention.

     Biological Activity of Selective Androgen Receptor Modulators 
     The selective androgen receptor modulators provided herein are a new class of compounds, which suppress growth of AR-positive breast cancers. The compounds of this invention have a tissue-selective myoanabolic activity profile of a nonsteroidal ligand for the androgen receptor. Furthermore compounds of the present invention are non-aromatizable, non-virilizing, and are not commonly cross-reactive with ER and PR. In addition, in one embodiment, the selective androgen receptor modulators (SARMs) of the present invention are beneficial to refractory breast cancer patients undergoing chemotherapy due to anabolism. 
     As contemplated herein, the appropriately substituted selective androgen receptor modulators of the present invention are useful for: a) treating a subject suffering from breast cancer; b) treating a subject suffering from metastatic breast cancer; c) treating a subject suffering from refractory breast cancer; d) treating a subject suffering from AR-positive breast cancer; e) treating a subject suffering from AR-positive refractory breast cancer; f) treating a subject suffering from AR-positive metastatic breast cancer; g) treating a subject suffering from AR-positive and ER-positive breast cancer; h) treating a subject suffering from AR-positive breast cancer with or without expression of ER, PR, and/or HER2; i) treating a subject suffering from triple negative breast cancer; j) treating a subject suffering from advanced breast cancer; k) treating a subject suffering from breast cancer that has failed SERM (tamoxifen, toremifene), aromatase inhibitor, palbociclib (Ibrance), trastuzumab (Herceptin, ado-trastuzumab emtansine), pertuzumab (Perjeta), lapatinib, exemestane (Aromasin), bevacizumab (Avastin), and/or fulvestrant treatments; l) treating a subject suffering from ER-positive breast cancer; m) treating, preventing, suppressing or inhibiting metastasis in a subject suffering from breast cancer; n) prolonging survival of a subject with breast cancer; o) slowing the progression of breast cancer in a subject; p) prolonging progression-free survival of a subject with breast cancer; and/or q) treating HER2-positive breast cancer 
     In one embodiment, a “refractory breast cancer” is a breast cancer that has not responded to treatment. In another embodiment, a “refractory breast cancer” is a breast cancer resistant to treatment. In one embodiment, refractory breast cancer is refractory metastatic breast cancer. In one embodiment, refractory breast cancer has not responded to treatment with anthracyclines, taxanes, capecitabine, ixabepilone, SERM (tamoxifen, toremifene), aromatase inhibitor, palbociclib (Ibrance), trastuzumab (Herceptin, ado-trastuzumab emtansine), pertuzumab (Perjeta), lapatinib, exemestane (Aromasin), bevacizumab (Avastin), fulvestrant or any combination thereof. 
     In one embodiment, a “triple negative breast cancer” is defined by lack of expression of estrogen, progesterone, and ErbB2 (also known as human epidermal growth factor receptor 2 (HER2)) receptors. This subgroup accounts for 15% of all types of breast cancer. This subtype of breast cancer is clinically characterized as more aggressive and less responsive to standard treatment and associated with poorer overall patient prognosis. 
     In one embodiment, the methods of this invention are directed to treating a subject suffering from AR-positive breast cancer, regardless of grade, stage or prior treatments. 
     In one embodiment, the methods of this invention are directed to treating a subject suffering from HER2-positive breast cancer, regardless of grade, stage or prior treatments. 
     In one embodiment, the methods of this invention are first, second, third, or fourth line therapies for breast cancer. A first line therapy refers to a medical therapy recommended for the initial treatment of a disease, sign or symptom. A second line therapy therapy is given when initial treatment (first-line therapy) does not work, or stops working. Third line therapy is given when both initial treatment (first-line therapy) and subsequent treatment (second-line therapy) does not work, or stop working, etc. 
     As used herein, “kinases” are a group of enzymes that catalyze the transfer of a phosphate group from a donor, such as ADP or ATP, to an acceptor. In one embodiment, phosphorylation results in a functional change of the target protein (substrate) by changing enzyme activity, cellular location, or association with other protein kinases. Kinases regulate the majority of cellular pathways, especially those involved in signal transduction. In one embodiment, deregulated kinase activity is a frequent cause of disease, in particular cancer, wherein kinases regulate many aspects that control cell growth, movement and death. In one embodiment, drugs that inhibit specific kinases are used to treat kinase-related diseases, including cancer. In one embodiment, HER2-positive breast cancers are susceptible to HER2 kinase inhibitors (e.g., trastuzumab and lapatinib) and are generally used in metastatic disease. However, some breast cancers are refractory to HER2 kinase inhibitor treatment. 
     As used herein, receptors for extracellular signaling molecules are collectively referred to as “cell signaling receptors”. Many cell signaling receptors are transmembrane proteins on a cell surface; when they bind an extracellular signaling molecule (i.e., a ligand), they become activated so as to generate a cascade of intracellular signals that alter the behavior of the cell. In contrast, in some cases, the receptors are inside the cell and the signaling ligand has to enter the cell to activate them; these signaling molecules therefore must be sufficiently small and hydrophobic to diffuse across the plasma membrane of the cell. 
     Steroid hormones are one example of small hydrophobic molecules that diffuse directly across the plasma membrane of target cells and bind to intracellular cell signaling receptors. These receptors are structurally related and constitute the intracellular receptor superfamily (or steroid-hormone receptor superfamily). Steroid hormone receptors include but are not limited to progesterone receptors, estrogen receptors, androgen receptors, glucocorticoid receptors, and mineralocorticoid receptors. In one embodiment, the present invention is directed to androgen receptors. In one embodiment, the present invention is directed to androgen receptor agonists. In one embodiment, the present invention is directed to progesterone receptors. In one embodiment, the present invention is directed to progesterone receptor antagonists. 
     In addition to ligand binding to the receptors, the receptors can be blocked to prevent ligand binding. When a substance binds to a receptor, the three-dimensional structure of the substance fits into a space created by the three-dimensional structure of the receptor in a ball and socket configuration. The better the ball fits into the socket, the more tightly it is held. This phenomenon is called affinity. If the affinity of a substance is greater than the original hormone, it will compete with the hormone and bind the binding site more frequently. Once bound, signals may be sent through the receptor into the cells, causing the cell to respond in some fashion. This is called activation. On activation, the activated receptor then directly regulates the transcription of specific genes. But the substance and the receptor may have certain attributes, other than affinity, in order to activate the cell. Chemical bonds between atoms of the substance and the atoms of the receptors may form. In some cases, this leads to a change in the configuration of the receptor, which is enough to begin the activation process (called signal transduction). 
     In one embodiment, the compounds of this invention inhibit the intratumoral expression of genes and pathways that promote breast cancer development through their actions on the AR. In one embodiment, a compound of this invention inhibits intratumoral expression of Muc1, SLUG, VCAM1, SPARC or MMP2, or any combination thereof. In another embodiment, Formula VIII inhibits gene expression that promotes breast cancer. 
     In one embodiment, a receptor antagonist is a substance which binds receptors and inactivates them. In one embodiment, a selective androgen receptor modulator is a molecule that exhibits in vivo tissue selectivity, activating signaling activity of the androgen receptor (AR) in anabolic (muscle, bone, etc.) tissues to a greater extent than in the androgenic tissues. Thus, in one embodiment, the selective androgen receptor modulators of the present invention are useful in binding to and activating steroidal hormone receptors. In one embodiment, the SARM compound of the present invention is an agonist which binds the androgen receptor. In another embodiment, the compound has high affinity for the androgen receptor. 
     Assays to determine whether the compounds of the present invention are AR agonists or antagonists are well known to a person skilled in the art. For example, AR agonistic activity can be determined by monitoring the ability of the selective androgen receptor modulators to maintain and/or stimulate the growth of AR containing androgenic tissue such as prostate and seminal vesicles, as measured by weight, in castrated animals. AR antagonistic activity can be determined by monitoring the ability of the selective androgen receptor modulators to inhibit the growth of AR containing tissue in intact animals or counter the effects of testosterone in castrated animals. 
     An androgen receptor (AR) is an androgen receptor of any species, for example a mammal. In one embodiment, the androgen receptor is an androgen receptor of a human. Thus, in another embodiment, the selective androgen receptor modulators bind reversibly to an androgen receptor of a human. In another embodiment, the selective androgen receptor modulators bind reversibly to an androgen receptor of a mammal. 
     As contemplated herein, the term “selective androgen receptor modulator” (SARM) refers to, in one embodiment, a molecule that exhibits in vivo tissue selectivity, activating signaling activity of the androgen receptor in anabolic (muscle, bone, etc.) tissues to a greater extent than in the androgenic tissues. In another embodiment, a selective androgen receptor modulator selectively binds the androgen receptor. In another embodiment, a selective androgen receptor modulator selectively affects signaling through the androgen receptor. In one embodiment, the SARM is a partial agonist. In one embodiment, the SARM is a tissue-selective agonist, or in some embodiments, a tissue-selective antagonist. 
     In one embodiment, a SARM of this invention exerts its effects on the androgen receptor in a tissue-dependent manner. In one embodiment, a SARM of this invention will have an IC 50  or EC 50  with respect to AR, as determined using AR transactivation assays, as known in the art, or, in other embodiments, as described herein. 
     The term “IC 50 ” refers, in some embodiments, to a concentration of the SARM which reduces the activity of a target (e.g., AR) to half-maximal level. 
     The term “EC 50 ” refers, in some embodiments, to a concentration of the SARM that produces a half-maximal effect. 
     For example, utilizing transactivation assays,  FIG. 5  shows that compounds of this invention exhibit AR agonist activity in MDA-MB-231 cells transfected with AR. 
     As defined herein, “contacting” means that the selective androgen receptor modulators of the present invention are introduced into a sample containing the receptor in a test tube, flask, tissue culture, chip, array, plate, microplate, capillary, or the like, and incubated at a temperature and time sufficient to permit binding of the selective androgen receptor modulators to the receptor. Methods for contacting the samples with the selective androgen receptor modulators or other specific binding components are known to those skilled in the art and may be selected depending on the type of assay protocol to be run. Incubation methods are also standard and are known to those skilled in the art. 
     In another embodiment, the term “contacting” means that the selective androgen receptor modulators of the present invention are introduced into a subject receiving treatment, and the selective androgen receptor modulator is allowed to come in contact with the androgen receptor in vivo. 
     As used herein, the term “treating” includes disorder remitative treatment. As used herein, the terms “reducing”, “suppressing” and “inhibiting” have their commonly understood meaning of lessening or decreasing. As used herein, the term “progression” means increasing in scope or severity, advancing, growing or becoming worse. As used herein, the term “recurrence” means the return of a disease after a remission. As used herein, the term “delaying” means stopping, hindering, slowing down, postponing, holding up or setting back. As used herein, the term “metastasis” refers to the transfer of a disease from one organ or part thereof to another not directly connected with it. Metastasis can occur for example as a result of transfer of malignant cells from one organ (for example breast) to other organs. 
     In one embodiment, “treating” refers to reducing tumor growth by 75%, as demonstrated in Example 8. In another embodiment, treating refers to reducing tumor growth by at least 75%. In another embodiment, treating refers to reducing tumor growth by at least 50%. In another embodiment, treating refers to reducing tumor growth by at least 25%.

     In one embodiment, the methods of the present invention comprise administering a pharmaceutical composition (or pharmaceutical preparation, used herein interchangeably) comprising the selective androgen receptor modulator of the present invention and/or its analog, derivative, isomer, metabolite, pharmaceutical product, hydrate, N-oxide, polymorph, crystal, prodrug or any combination thereof; and a suitable carrier or diluent. 
     Pharmaceutical Compositions: 
     As used herein, “pharmaceutical composition” means therapeutically effective amounts of the selective androgen receptor modulator together with suitable diluents, preservatives, solubilizers, emulsifiers, adjuvant and/or carriers. A “therapeutically effective amount” as used herein refers to that amount which provides a therapeutic effect for a given condition and administration regimen. Such compositions are liquids or lyophilized or otherwise dried formulations and include diluents of various buffer content (e.g., Tris-HCl, acetate, phosphate), pH and ionic strength, additives such as albumin or gelatin to prevent absorption to surfaces, detergents (e.g., Tween 20®, Tween 80®, Pluronic F68®, bile acid salts), solubilizing agents (e.g., glycerol, polyethylene glycerol), anti-oxidants (e.g., ascorbic acid, sodium metabisulfite), preservatives (e.g., Thimerosal®, benzyl alcohol, parabens), bulking substances or tonicity modifiers (e.g., lactose, mannitol), covalent attachment of polymers such as polyethylene glycol to the protein, complexation with metal ions, or incorporation of the material into or onto particulate preparations of polymeric compounds such as polylactic acid, polglycolic acid, hydrogels, etc, or onto liposomes, microemulsions, micelles, unilamellar or multilamellar vesicles, erythrocyte ghosts, or spheroplasts). Such compositions will influence the physical state, solubility, stability, rate of in vivo release, and rate of in vivo clearance. Controlled or sustained release compositions include formulation in lipophilic depots (e.g., fatty acids, waxes, oils). 
     In one embodiment, the pharmaceutical compositions comprising the compounds of this invention make use in the methods of this invention of a dosage of between 1 and 50 mg of a compound of this invention. In another embodiment, the dosage is 1 mg, 3 mg, 9 mg, 10 mg, 18 mg or 30 mg of the compound of this invention. In another embodiment, the pharmaceutical compositions comprising the compounds of this invention make use in the methods of this invention of a dosage of 1 mg of a compound of this invention. In another embodiment, the pharmaceutical compositions comprising the compounds of this invention make use in the methods of this invention of a dosage of 3 mg of a compound of this invention. In another embodiment, the pharmaceutical compositions comprising the compounds of this invention make use in the methods of this invention of a dosage of 9 mg of a compound of this invention. In another embodiment, the pharmaceutical compositions comprising the compounds of this invention make use in the methods of this invention of a dosage of 10 mg of a compound of this invention. In another embodiment, the pharmaceutical compositions comprising the compounds of this invention make use in the methods of this invention of a dosage of 18 mg of a compound of this invention. In another embodiment, the pharmaceutical compositions comprising the compounds of this invention make use in the methods of this invention of a dosage of 30 mg of a compound of this invention. 
     Also comprehended by the invention are particulate compositions coated with polymers (e.g., poloxamers or poloxamines). Other embodiments of the compositions of the invention incorporate particulate forms protective coatings, protease inhibitors or permeation enhancers for various routes of administration, including parenteral, pulmonary, nasal and oral. In one embodiment the pharmaceutical composition is administered parenterally, paracancerally, transmucosally, transdermally, intramuscularly, intravenously, intradermally, subcutaneously, intraperitoneally, intraventricularly, intravaginally, intracranially and intratumorally. 
     Further, as used herein “pharmaceutically acceptable carriers” are well known to those skilled in the art and include, but are not limited to, 0.01-0.1 M and preferably 0.05 M phosphate buffer or about 0.8% saline. Additionally, such pharmaceutically acceptable carriers may be aqueous or non-aqueous solutions, suspensions, and emulsions. Examples of non-aqueous solvents are propylene glycol, polyethylene glycol, vegetable oils such as olive oil, and injectable organic esters such as ethyl oleate. Aqueous carriers include water, alcoholic/aqueous solutions, emulsions or suspensions, including saline and buffered media. 
     Parenteral vehicles include sodium chloride solution, Ringer&#39;s dextrose, dextrose and sodium chloride, lactated Ringer&#39;s and fixed oils. Intravenous vehicles include fluid and nutrient replenishers, electrolyte replenishers such as those based on Ringer&#39;s dextrose, and the like. Preservatives and other additives may also be present, such as, for example, antimicrobials, antioxidants, collating agents, inert gases and the like. 
     Controlled or sustained release compositions include formulation in lipophilic depots (e.g. fatty acids, waxes, oils). Also comprehended by the invention are particulate compositions coated with polymers (e.g. poloxamers or poloxamines) and the compound coupled to antibodies directed against tissue-specific receptors, ligands or antigens or coupled to ligands of tissue-specific receptors. 
     Other embodiments of the compositions of the invention incorporate particulate forms, protective coatings, protease inhibitors or permeation enhancers for various routes of administration, including parenteral, pulmonary, nasal and oral. 
     Compounds modified by the covalent attachment of water-soluble polymers such as polyethylene glycol, copolymers of polyethylene glycol and polypropylene glycol, carboxymethyl cellulose, dextran, polyvinyl alcohol, polyvinylpyrrolidone or polyproline are known to exhibit substantially longer half-lives in blood following intravenous injection than do the corresponding unmodified compounds (Abuchowski et al., 1981; Newmark et al., 1982; and Katre et al., 1987). Such modifications may also increase the compound&#39;s solubility in aqueous solution, eliminate aggregation, enhance the physical and chemical stability of the compound, and greatly reduce the immunogenicity and reactivity of the compound. As a result, the desired in vivo biological activity may be achieved by the administration of such polymer-compound abducts less frequently or in lower doses than with the unmodified compound. 
     In yet another embodiment, the pharmaceutical composition can be delivered in a controlled release system. For example, the agent may be administered using intravenous infusion, an implantable osmotic pump, a transdermal patch, liposomes, or other modes of administration. In one embodiment, a pump may be used (see Langer, supra; Sefton, CRC Crit. Ref. Biomed. Eng. 14:201 (1987); Buchwald et al., Surgery 88:507 (1980); Saudek et al., N. Engl. J. Med. 321:574 (1989). In another embodiment, polymeric materials can be used. In yet another embodiment, a controlled release system can be placed in proximity to the therapeutic target, i.e., the brain, thus requiring only a fraction of the systemic dose (see, e.g., Goodson, in Medical Applications of Controlled Release, supra, vol. 2, pp. 115-138 (1984). Other controlled release systems are discussed in the review by Langer (Science 249:1527-1533 (1990). 
     The pharmaceutical preparation can comprise the selective androgen receptor modulator alone, or can further include a pharmaceutically acceptable carrier, and can be in solid or liquid form such as tablets, powders, capsules, pellets, solutions, suspensions, elixirs, emulsions, gels, creams, or suppositories, including rectal and urethral suppositories. Pharmaceutically acceptable carriers include gums, starches, sugars, cellulosic materials, and mixtures thereof. The pharmaceutical preparation containing the selective androgen receptor modulator can be administered to a subject by, for example, subcutaneous implantation of a pellet; in a further embodiment, the pellet provides for controlled release of selective androgen receptor modulator over a period of time. The preparation can also be administered by intravenous, intraarterial, or intramuscular injection of a liquid preparation, oral administration of a liquid or solid preparation, or by topical application Administration can also be accomplished by use of a rectal suppository or a urethral suppository. 
     The pharmaceutical preparations of the invention can be prepared by known dissolving, mixing, granulating, or tablet-forming processes. For oral administration, the selective androgen receptor modulators or their physiologically tolerated derivatives such as salts, esters, N-oxides, and the like are mixed with additives customary for this purpose, such as vehicles, stabilizers, or inert diluents, and converted by customary methods into suitable forms for administration, such as tablets, coated tablets, hard or soft gelatin capsules, aqueous, alcoholic or oily solutions. Examples of suitable inert vehicles are conventional tablet bases such as lactose, sucrose, or cornstarch in combination with binders such as acacia, cornstarch, gelatin, with disintegrating agents such as cornstarch, potato starch, alginic acid, or with a lubricant such as stearic acid or magnesium stearate. 
     Examples of suitable oily vehicles or solvents are vegetable or animal oils such as sunflower oil or fish-liver oil. Preparations can be effected both as dry and as wet granules. For parenteral administration (subcutaneous, intravenous, intraarterial, or intramuscular injection), the selective androgen receptor modulators or their physiologically tolerated derivatives such as salts, esters, N-oxides, and the like are converted into a solution, suspension, or emulsion, if desired with the substances customary and suitable for this purpose, for example, solubilizers or other auxiliaries. Examples are sterile liquids such as water and oils, with or without the addition of a surfactant and other pharmaceutically acceptable adjuvants. Illustrative oils are those of petroleum, animal, vegetable, or synthetic origin, for example, peanut oil, soybean oil, or mineral oil. In general, water, saline, aqueous dextrose and related sugar solutions, and glycols such as propylene glycols or polyethylene glycol are preferred liquid carriers, particularly for injectable solutions. 
     The preparation of pharmaceutical compositions which contain an active component is well understood in the art. Such compositions can be prepared as aerosols of the active component delivered to the nasopharynx or as injectables, either as liquid solutions or suspensions; however, solid forms suitable for solution in, or suspension in, liquid prior to injection can also be prepared. The preparation can also be emulsified. The active therapeutic ingredient is often mixed with excipients which are pharmaceutically acceptable and compatible with the active ingredient. Suitable excipients are, for example, water, saline, dextrose, glycerol, ethanol, or the like or any combination thereof. 
     In addition, the composition can contain minor amounts of auxiliary substances such as wetting or emulsifying agents, pH buffering agents which enhance the effectiveness of the active ingredient. 
     An active component can be formulated into the composition as neutralized pharmaceutically acceptable salt forms. Pharmaceutically acceptable salts include the acid addition salts (formed with the free amino groups of the polypeptide or antibody molecule), which are formed with inorganic acids such as, for example, hydrochloric or phosphoric acids, or such organic acids as acetic, oxalic, tartaric, mandelic, and the like. Salts formed from the free carboxyl groups can also be derived from inorganic bases such as, for example, sodium, potassium, ammonium, calcium, or ferric hydroxides, and such organic bases as isopropylamine, trimethylamine, 2-ethylamino ethanol, histidine, procaine, and the like. 
     For topical administration to body surfaces using, for example, creams, gels, drops, and the like, the selective androgen receptor modulators or their physiologically tolerated derivatives such as salts, esters, N-oxides, and the like are prepared and applied as solutions, suspensions, or emulsions in a physiologically acceptable diluent with or without a pharmaceutical carrier. 
     In another embodiment, the active compound can be delivered in a vesicle, in particular a liposome (see Langer, Science 249:1527-1533 (1990); Treat et al., in Liposomes in the Therapy of Infectious Disease and Cancer, Lopez-Berestein and Fidler (eds.), Liss, New York, pp. 353-365 (1989); Lopez-Berestein, ibid., pp. 317-327; see generally ibid). 
     For use in medicine, the salts of the selective androgen receptor modulator will be pharmaceutically acceptable salts. Other salts may, however, be useful in the preparation of the compounds of the invention or of their pharmaceutically acceptable salts. Suitable pharmaceutically acceptable salts of the compounds of this invention include acid addition salts which may, for example, be formed by mixing a solution of the compound of the invention with a solution of a pharmaceutically acceptable acid such as hydrochloric acid, sulphuric acid, methanesulphonic acid, fumaric acid, maleic acid, succinic acid, acetic acid, benzoic acid, oxalic acid, citric acid, tartaric acid, carbonic acid or phosphoric acid. 
     In one embodiment, the term “about”, refers to a deviance of between 0.0001-5% from the indicated number or range of numbers. In one embodiment, the term “about”, refers to a deviance of between 1-10% from the indicated number or range of numbers. In one embodiment, the term “about”, refers to a deviance of up to 25% from the indicated number or range of numbers. 
     In some embodiments, the term “comprise” or grammatical forms thereof, refers to the inclusion of the indicated active agent, such as the compound of this invention, as well as inclusion of other active agents, and pharmaceutically acceptable carriers, excipients, emollients, stabilizers, etc., as are known in the pharmaceutical industry. In some embodiments, the term “consisting essentially of” refers to a composition, whose only active ingredient is the indicated active ingredient, however, other compounds may be included which are for stabilizing, preserving, etc. the formulation, but are not involved directly in the therapeutic effect of the indicated active ingredient. In some embodiments, the term “consisting essentially of” may refer to components, which exert a therapeutic effect via a mechanism distinct from that of the indicated active ingredient. In some embodiments, the term “consisting essentially of” may refer to components, which exert a therapeutic effect and belong to a class of compounds distinct from that of the indicated active ingredient. In some embodiments, the term “consisting essentially of” may refer to components, which exert a therapeutic effect and belong to a class of compounds distinct from that of the indicated active ingredient, by acting via a different mechanism of action, for example, and representing an embodiment of this invention, polypeptides comprising T cell epitopes present in a composition may be specifically combined with polypeptides comprising B cell epitopes. In some embodiments, the term “consisting essentially of” may refer to components which facilitate the release of the active ingredient. In some embodiments, the term “consisting” refers to a composition, which contains the active ingredient and a pharmaceutically acceptable carrier or excipient. 
     Further, as used herein, the term “comprising” is intended to mean that the system includes the recited elements, but not excluding others which may be optional. By the phrase “consisting essentially of” it is meant a method that includes the recited elements but exclude other elements that may have an essential significant effect on the performance of the method. “Consisting of” shall thus mean excluding more than traces of other elements. Embodiments defined by each of these transition terms are within the scope of this invention. 
     In one embodiment, the present invention provides combined preparations. In one embodiment, the term “a combined preparation” defines especially a “kit of parts” in the sense that the combination partners as defined above can be dosed independently or by use of different fixed combinations with distinguished amounts of the combination partners i.e., simultaneously, concurrently, separately or sequentially. In some embodiments, the parts of the kit of parts can then, e.g., be administered simultaneously or chronologically staggered, that is at different time points and with equal or different time intervals for any part of the kit of parts. The ratio of the total amounts of the combination partners, in some embodiments, can be administered in the combined preparation. In one embodiment, the combined preparation can be varied, e.g., in order to cope with the needs of a patient subpopulation to be treated or the needs of the single patient which different needs can be due to a particular disease, severity of a disease, age, sex, or body weight as can be readily made by a person skilled in the art. 
     In one embodiment, the term “a” or “one” or “an” refers to at least one. In one embodiment the phrase “two or more” may be of any denomination, which will suit a particular purpose. In one embodiment, “about” may comprise a deviance from the indicated term of +1%, or in some embodiments, −1%, or in some embodiments, ±2.5%, or in some embodiments, ±5%, or in some embodiments, ±7.5%, or in some embodiments, ±10%, or in some embodiments, ±15%, or in some embodiments, ±20%, or in some embodiments, ±25%. 
     The following examples are presented in order to more fully illustrate the preferred embodiments of the invention. They should in no way be construed, however, as limiting the broad scope of the invention. 
     EXPERIMENTAL DETAILS SECTION 
     General Experimental Methods 
     Cell Growth Conditions 
     HCC 1937, HCC 1954, HCC 38, T47D-Kbluc, MDA-MB-453, and MDA-MB-231 cells were grown in RPMI-1640 medium containing 2 mM L-glutamine supplemented with 10% fetal bovine serum (FBS). Cells were maintained in a 5% CO 2 /95% air humidified atmosphere at 37° C. MCF-7 cells were grown in Minimum Essential Medium supplemented with 10% FBS. 
     Breast cancer tumors typically express AR 70-90% of the time, however breast cancer cell lines typically do not express AR. This makes development of a preclinical model for the study of androgen effects on breast cancer very difficult. Consequently, the AR has been introduced by adenoviral infection (stably incorporated into the genome) into some breast cancer cell lines used in the studies below. 
     Sulforhodamine B (SRB) Assay 
     The SRB assay was used to determine cell number during cytotoxocity experiments. The following protocol was used:
         1. Cells were detached with 0.25% trypsin.   2. Experimental cultures were cultured in 96-well microtiter plates (200 uL growth medium per well; 1,000-200,000 cells per well).   3. Cultures were fixed with 50 uL 50% TCA (4° C.). (see cell fixation protocol for details).   4. Fixed cells were stained with 50 uL 0.4% (wt/vol) SRB in 1% acetic acid for 10 minutes.   5. SRB was removed and the cultures were quickly* rinsed 5 times with 1% acetic acid to remove unbound dye.**   6. Cultures were air-dried overnight until there was no visible moisture.   7. The cellular protein-bound SRB was dissolved with 200 uL unbuffered Tris base (10 mM, pH 10.5) for 30 minutes on a rocking platform shaker.   8. Absorbance was read at 540 nm.
 
* quickly performing rinsing process was to prevent desorption of protein-bound SRB
 
** completely removed residual wash solution by sharply flicking plates over sink.
 
Fixation of Cells Attached to the Plastic Substratum
       

     The following protocol was used for fixing cells:
     a. 50 uL of 50% TCA (4° C.) was gently layered on the top of growth medium in each well to make a final TCA concentration of 10%.   b. Cultures were incubated at 4° C. for 1 hour.   c. Cultures were washed 5 times with tap water to remove TCA, growth medium, low-molecular-weight metabolites, and serum protein.   d. Plates were air-dried until there was no visible moisture.   

     EXAMPLE 1 
     Effect of Formula IX on Growth in Different Breast Cancers Cell Lines Expressing Androgen Receptor 
     Materials and Methods 
     MDA-MB-231 and HCC-38 triple negative breast cancer cells were used to analyze growth effects of various compounds. 
     MDA-MB-231 and HCC-38 triple negative breast cancer cells were infected with 200 μL or 500 μL adenovirus containing LacZ (negative control) or AR, and were treated with various AR ligands (agonists: DHT and Formula IX, and antagonist: bicalutamide) or a non-AR binder that is structurally similar to Formula IX, R-enantiomer of Formula IX. Cells were treated in charcoal stripped FBS ( FIGS. 1C, 1E, 1G and 1I ;  2 C,  2 E and  2 G or full serum ( FIGS. 1D, 1F, 1H and 1J ;  2 D,  2 F and  2 H for 3 days, fixed and stained with sulforhodamine blue (SRB) to measure cell viability. IC 50  values were calculated. 
     Results 
     Expression of AR in cells infected with AR or LacZ was evaluated using Western blotting ( FIG. 1A  and  FIG. 2A ). 
     Only the AR agonists, DHT and Formula IX, inhibited MDA-MB-231 and HCC-38 triple negative breast cancer cell growth ( FIGS. 1C, 1D, 1E, 1F  and  FIGS. 2C, 2D, 2E and 2F . This inhibition was observed only in the presence of AR (compare w/lacZ and w/AR). IC 50  values in AR-positive cells for DHT and Formula IX are presented in  FIG. 1B  and  FIG. 2B . 
     EXAMPLE 2 
     Reversal of Effect of Formula IX on Growth 
     Materials and Methods 
     To determine if the growth inhibition observed with DHT and Formula IX in AR-positive cells is AR dependent, MDA-MB-231 cells were infected with adenovirus containing LacZ (negative control) or AR and were treated with AR agonists, DHT or Formula IX, in the presence or absence of the AR antagonist, bicalutamide. Cells were treated in charcoal stripped FBS ( FIGS. 3A and 3C  or full serum ( FIGS. 3B and 3D  for 3 days, fixed and stained with sulforhodamine blue (SRB) to measure cell viability. IC 50  values were calculated. 
     Results 
     Both DHT and Formula IX required AR to inhibit MDA-MB-231 cell growth, as demonstrated by the weakened growth inhibitory effects in the presence of bicalutamide ( FIGS. 3A-3D ). IC 50  values for DHT and Formula IX in AR-positive cells pretreated with or without bicalutamide are presented in  FIG. 3E . 
     EXAMPLE 3 
     Effect of AR Ligands on Breast Cancer Cell Growth 
     Materials and Methods 
     To determine if all AR ligands inhibit the growth of triple negative breast cancer cells, MDA-MB-231 cells were infected with adenovirus containing LacZ or AR and were treated with various AR ligands (agonists: DHT, Formula VIII, Formula IX, Formula X, Formula XIII, Formula XIV; antagonist: bicalutamide) and a non-AR-binder: R-enantiomer of Formula IX. Cells were treated in charcoal stripped FBS ( FIGS. 4A, 4C, 4E, 4G, 4I, 4K, 4M and 4O  or full serum ( FIGS. 4B, 4D, 4F, 4H, 4J, 4L, 4N and 4P  for 3 days, fixed and stained with sulforhodamine blue (SRB) to measure cell viability. Anti-proliferative IC 50  values were calculated in breast cancer cells and compared to transactivation values, i.e., EC 50  (agonists) and IC 50  (antagonists) values, generated in HEK-293 cells. The growth regulatory properties in breast cancer cells of these molecules in breast cancer cells are comparable to the transactivation values obtained in HEK-293 cells. 
     Results 
     Only AR agonists inhibited the growth of MDA-MB-231 cells ( FIGS. 4A, 4B, 4E-4H, and 4K-4P  and the growth inhibitory potential of these ligands rank order with their agonistic activity observed in HEK-293 cells ( FIG. 4Q ). 
     Example 4 demonstrates as well that AR agonists inhibited the proliferation of MDA-MB-231 cells stably transfected with AR.

     AR Transactivation Assays In Breast Cancer Cells 
     Materials and Methods 
     To ensure that the ligands that elicited growth inhibitory properties are agonists in MDA-MB-231 cells, AR transactivation assays were performed in MDA-MB-231 cells. Though AR transactivation assay was performed in HEK-293 cells, the ability of ligands to function as agonists or antagonists depends on cellular microenvironment. Hence, MDA-MB-231 cells were transfected using lipofectamine with AR, GRE-LUC and CMV-LUC as normalization control. The cells were treated 24 h after transfection and luciferase assay performed 48 h after transfection. 
     Results 
       FIG. 5  shows that all AR ligands that elicited anti-proliferative activity are agonists in MDA-MB-231 cells transfected with AR and their agonist and growth inhibitory properties compare well. In other words, growth inhibitory ligands are AR agonists in MDA-MB-231 cells transfected with AR. 
     EXAMPLE 5 
     Analysis of Growth Inhibitory Effects in Breast Cancer Cells Expressing Estrogen Receptor 
     Materials and Methods 
     To ensure that growth inhibitory effects in MDA-MB-231 cells are selective to AR, and to determine if the ligand dependent growth inhibitory effects are exclusive to AR and also to ensure that the effects are not artifacts of adenoviral infection, MDA-MB-231 triple negative breast cancer cells were infected with ER-α or ER-β adenovirus constructs and were treated with ER agonist: estradiol (E2) or ER antagonist: ICI 182,780 (ICI) in charcoal stripped serum ( FIG. 6C ) 
     or full serum ( FIGS. 6D and 6E ) for 3 days. Cells were fixed and stained with sulforhodamine blue (SRB) to measure cell viability. Expression of ER in infected cells was evaluated using Western blotting. 
     Results 
       FIGS. 6A-6B  show the presence or absence of ERα or ERβ in MDA-MB-231 cells following transfection. These results show that the anti-proliferative effects observed with androgens is unique to ligand activated AR and not an artifact of adenovirus.  FIGS. 6C-6E  show that over-expression of ER-α or ER-β in MDA-MB-231 cells failed to promote growth inhibition either in the presence of ER agonists or antagonists. Thus, the observed growth inhibitory effects in MDA-MB-231 cells are selective to the presence of the AR and AR agonists. 
     EXAMPLE 6 
     Effect of AR Agonist on Morphology of Breast Cancer Cells 
     Materials and Methods 
     MDA-MB-231 cells were stably transfected with AR using lentivirus. Following transfection, cells were treated for 3 days with the indicated concentrations of DHT or bicalutamide. Live cells were visualized using a light-microscope and photographed. The cells were imaged at the same magnification and under the same microscopic conditions. 
     Results 
       FIG. 7  shows that DHT altered the morphology of MDA-MB-231 cells into more anchorage dependent and differentiated cells, indicating that AR agonist-bound AR expressing breast cancer cells will have less invasive and migratory properties (e.g., less likely to metastasize). 
     DHT and SARMs alter the morphology of AR-positive MDA-MB-231 cells. MDA-MB-231 cells were stably transfected with AR using lentivirus and were treated with vehicle or AR agonists at the indicated concentrations. At the end of 3 days of incubation, the cells were imaged under a microscope (40×). 
     DHT and SARMs, but not the AR antagonist, bicalutamide (data not shown), or the inactive isomer of Formula IX, altered the morphology of the cells into a more anchorage-dependent phenotype ( FIG. 12 ). 
     EXAMPLE 7 
     Cross-Reactivity of Formula VIII with Other Nuclear Hormone Receptors 
     In order to determine whether compounds of this invention affected other nuclear hormone receptor signaling, the ability of a compound represented by Formula VIII to stimulate (agonist) or inhibit (antagonist) ERα-, ERβ-, GR-, PR-, or MR-mediated transcriptional activation, was analyzed. 
     Materials and Methods 
     Transient Transfection 
     Rat GR, MR, PR, ER-α and ER-β were individually cloned into a pCR3.1 vector backbone. Sequencing was performed to verify the absence of any mutations. HEK-293 cells were plated at 90,000 cells per well of a 24 well plate in Dulbecco&#39;s Minimal Essential Media supplemented with 5% charcoal-stripped FBS. The cells were transfected using Lipofectamine (Invitrogen, Carlsbad, Calif.) with 0.25 μg GRE-LUC for GR, MR and PR and ERE-LUC for ER-α and ER-β, 0.5 ng CMV-LUC (renilla luciferase) and 12.5-25 ng of the respective expression vector for each receptor. The cells were treated 24 h after transfection with Formula VIII in the absence (agonist mode) and presence (antagonist mode) of known agonists (estradiol for ER; dexamethasone for GR; aldosterone for MR; progesterone for PR) as controls. Luciferase assays were performed 48 h after transfection. Transcriptional activation values are represented as firefly luciferase normalized to renilla luciferase. 
     Results 
     The agonist effects of Formula VIII on ER-β, ER-α, GR, PR and MR were tested and compared to the activities of the known ligands, as well ( FIG. 8 ). A compound of Formula VIII failed to activate ER-β or ER-α even at the highest tested concentration (1 μM) whereas 1 nM estradiol induced ERα- and ERβ-mediated transactivation by 3- and 5-fold, respectively. A compound of Formula VIII failed to activate GR- or MR-mediated transactivation. A compound of Formula VIII at all the tested concentrations did not induce GR- or MR-mediated transactivation, whereas the known ligands (dexamethasone and aldosterone) induced the activities of GR or MR by 70- and 60-fold, respectively, at a concentration of 1 nM. However, a compound of Formula VIII increased the transactivation of PR at 1 μM and 10 μM by 3 and 8 fold, respectively. Progesterone activated PR by 23 fold at a 1 nM concentration, indicating that a compound of Formula VIII is greater than 10,000-fold weaker than the endogenous agonist for PR. 
     The ability of a compound of Formula VIII to inhibit the effects of a known agonist for each of the above mentioned receptors was tested as well. 
     Co-incubation of HEK 293 cells with the indicated concentrations of Formula VIII failed to alter the estradiol-induced ER-β or ER-α activity, dexamethasone-induced GR-mediated transactivation or aldosterone-induced MR-mediated transactivation. 
     A dose response curve for a compound of Formula VIII in antagonist mode demonstrated potent partial inhibition of PR activity ( FIG. 9 ). In comparison to Formula IX, Formula VIII is was 10-times more potent, and 100-times more potent than R-enantiomer of Formula IX. In comparison to RU486, Formula VIII was about 1,000 fold weaker as a PR antagonist, than RU486. 
     Compounds of Formulae VIII and IX are specific for the AR and do not stimulate or inhibit receptor-mediated transactivation of ERα, ERβ, GR, or MR. Unexpectedly, Formula VIII exhibited moderate potency partial agonist activity for PR, and potent PR partial antagonism (see  FIG. 9 ). Combined AR-agonism and PR-antagonism will be beneficial in certain breast cancers (e.g., PR-positive breast cancers). 
     EXAMPLE 8 
     Formula VIII and Formula IX Inhibit Triple Negative Breast Cancer Cell Tumor Growth in Mice 
     Materials and Methods 
     MDA-MB-231-AR triple negative breast cancer cells (2 million cells/mouse; MDA-MB-231 cells stably transfected with AR using lentivirus) were mixed with matrigel (1:1) and injected subcutaneously into the flanks of intact female nude mice (n=5/group). When the tumors reached 150-200 mm 3 , the animals were separated into two groups, one receiving vehicle and the other receiving 30 mg/kg Formula VIII orally. Tumor volume was measured thrice weekly and % tumor growth inhibition (TGI) was calculated. At the end of 35 days of treatment, the animals were sacrificed, tumors excised, weighed, and collected for various analyses. Blood was collected and serum separated for drug concentration measurement. 
     Results 
     Formula VIII significantly reduced the tumor growth with TGI of ˜75% ( FIG. 10B ). Tumor weights were also reduced by more than 50% by Formula VIII treatment ( FIG. 11C ) as were tumor size ( FIGS. 11A-11B ). Formula VIII elicited these results without any associated toxicity or changes in body weight ( FIG. 10A ). Uterus weight also increased in response to Formula VIII treatment (not shown), indicative of in vivo androgenic response. 
     The results presented in  FIG. 24  shows the increase of body weight by the SARMs at all doses of Formula VIII and Formula IX, indicative of healthy growth and a lack of toxicity. By comparison, the vehicle treated animal did not grow as robustly. 
     In summary, the Formula VIII SARM is extremely effective in regressing the growth of AR expressing triple negative breast cancer xenografts in mice, and is likely to be effective in a wide variety of AR-positive breast cancers in humans, as described supra and infra. 
     EXAMPLE 9 
     Effect of Formula IX in Women with Metastatic or ER and/or AR-Positive Refractory Breast Cancer 
     This clinical trial assessed the safety and efficacy of 9 mg of the compound represented by the structure of Formula IX (Formula IX), in 22 post-menopausal women who have estrogen receptor (ER) positive metastatic breast cancer, and who have responded previously to adjuvant and/or salvage endocrine therapy. The goal of this study was to determine the importance of the AR status as a therapeutic target in women with ER-positive metastatic breast cancer (MBC) that had previously responded to hormone therapy. The treatment was continued until disease progression (PD). 
     Primary endpoint was clinical benefit response (CBR) by 6 months (m) defined as patients having a complete response (CR), partial response (PR), or stable disease (SD). CBR will be correlated with AR status of metastatic tumor biopsy. 
     Serum prostate specific antigen (PSA) was evaluated as a biomarker of AR activity. 
     Results: Formula IX was well-tolerated, with no drug related serious adverse events and none exceeding Grade 3. Conclusions: Formula IX demonstrated promise as a novel targeted therapy for AR-positive MBC. The primary endpoint has been achieved, with 6/17 AR+ patients meeting statistical threshold for success, as outlined in the Table herein below. Serum PSA appeared to be a surrogate marker for AR activity and disease response. 
     Materials and Methods 
     Subject Population 
     Female subjects with ER-positive metastatic breast cancer who have previously been treated with up to 3 prior hormonal therapies for the treatment of breast cancer. Subjects must have been treated with and responded to previous adjuvant therapy for ≥3 years or hormonal therapy for metastatic disease for ≥6 months prior to progression. Details of subject selection criteria are presented below: 
     To be eligible for participation in this study, subjects must meet all of the following criteria, including give voluntary, signed informed consent in accordance with institutional policies; be a woman that has been diagnosed with ER-positive metastatic breast cancer; and be clinically confirmed as postmenopausal. Subjects must have undergone the onset of spontaneous, medical or surgical menopause prior to the start of this study. (Spontaneous menopause is defined as the natural cessation of ovarian function as indicated by being amenorrheic for at least 12 months. If the subject has been amenorrheic for ≥6 months but &lt;12 months they must have a serum FSH concentration of ≥50 mIU/mL and an estradiol concentration of ≤25 pg/mL; medical menopause is defined as treatment with a luteinizing hormone receptor hormone agonist; and surgical menopause is defined as bilateral oophorectomy). 
     Additional requirement that subjects must meet include that they have been treated and responded to previous adjuvant hormonal therapy for ≥3 years or previous hormonal therapy for metastatic disease for ≥6 months prior to disease progression; that they have not had radiation therapy for breast cancer within 2 weeks of randomization in this study and are not planned to have radiation therapy during participation in this study. Subjects must be willing to provide tissue sample from a biopsy of a metastatic tumor lesion(s) for determination of AR and ER status. Tissue samples from a biopsy of a primary tumor lesion will also be provided if available. Further subjects must have ECOG score≤2 and be age≥18 years. 
     Subjects with any of the following exclusion criteria will NOT be eligible for enrollment in this study: have triple negative breast cancer; have, in the judgment of the Investigator, a clinically significant concurrent illness or psychological, familial, sociological, geographical or other concomitant condition that would not permit adequate follow-up and compliance with the study protocol; have uncontrolled hypertension, congestive heart failure or angina; have Stage 4 chronic obstructive pulmonary disease (COPD); have positive screen for hepatitis B consisting of HBsAg (Hepatitis B Surface Antigen), unless subject was diagnosed&gt;10 years prior to enrollment and no evidence of active liver disease; have ALT/SGOT or AST/SGPT above 1.5 times the upper limit of normal (ULN); have positive screen for hepatitis A antibody IgM or HIV; have received chemotherapy for metastatic breast cancer within the 3 months prior to enrollment in the study or be expected to receive chemotherapy for metastatic breast cancer during the study; be currently taking testosterone, methyltestosterone, oxandrolone (Oxandrin®), oxymetholone, danazol, fluoxymesterone (Halotestin®), testosterone-like agents (such as dehydroepiandrosterone (DHEA), androstenedione, and other androgenic compounds, including herbals), or antiandrogens; previous therapy with testosterone and testosterone-like agents is acceptable with a 30-day washout (if previous testosterone therapy was long term depot within the past 6 months, the site should contact the medical monitor for this study to determine appropriate washout period); have untreated or uncontrolled brain metastasis; have been diagnosed with or treated for cancer within the previous two years, other than breast cancer or non-melanoma carcinoma of the skin 
     Androgen receptor (AR) status was assessed in all subjects from primary and/or metastatic lesions after enrollment. It was observed that the majority (17/19) of subjects with ER-positive breast cancer also expressed AR) in their primary tumor samples, which correlated well with previous literature which predicted 70-95% would be AR-positive (Niemeier L A, et. al. Androgen receptor in breast cancer: expression in estrogen receptor-positive tumors and in estrogen-negative tumors with apocrine differentiation.  Modern Pathology  23:205-212, 2010; Narita D, et al. Immunohistochemical expression of androgen receptor and prostate-specific antigen in breast cancer.  Folia Histochemica Et Cytobiologica  44:165-172, 2006). High percentages (72-84%) of metastatic lesions obtained from women with advanced breast cancer have also been found to be AR-positive (Lea O A. et al. Improved measurement of androgen receptors in human breast cancer.  Cancer Research  49:7162-7167, 1989). 
     As 70% or greater of the women with ER-positive breast cancer were expected to have tumors that are AR-positive, the study was designed to enroll approximately 27 subjects (of 40 originally intended to be enrolled) with AR-positive breast cancer in each dose arm, enabling assessment of the primary endpoint in AR-positive subjects, as well as the secondary and tertiary endpoints in subsets based on AR status (i.e., all subjects, AR-positive subjects, and AR-negative subjects). 
     At the time of this writing, patient demographics were: mean age 63.7 years, mean time from diagnosis 11.0 years, 72.7% prior chemotherapy, 89% (17/19) AR+, 41% detectable baseline PSA and 86.4% previous radiation.

Treatment
 
     Subjects received 9 mg daily dose of Formula IX, with baseline and regular on study assessments of safety and efficacy. 
     Measurable and non-measurable lesions (primary and/or metastatic) were identified and assessed by a modified Response Evaluation Criteria In Solid Tumors (RECIST 1.1) classification over the course of this study (described in detail below). 
     Study Duration 
     Each subject enrolled into this study received intervention until a progression free survival (PFS) endpoint has been reached (tumor progression or death). Subjects will be followed after treatment has been discontinued for vital status only. 
     Efficacy Endpoints 
     The primary efficacy analysis was the clinical benefit in subjects with AR-positive breast cancer at 6 months as measured by a modified Response Evaluation Criteria In Solid Tumors (RECIST 1.1) classification. Key secondary endpoints of clinical benefit in all subjects and AR-negative subjects, as well as objective response rate, progression free survival, time to progression, duration of response, incidence of SREs, and time to first SRE in subsets based on AR status (i.e., all subjects, AR-positive subjects, and AR-negative subjects) was also assessed. Effects on CA 27-29, PSA, bone turnover markers, QOL, and libido were assessed as tertiary endpoints. 
     Primary Endpoint 
     Clinical benefit in a subject is defined as a complete response [CR], a partial response [PR] or stable disease [SD] as measured by modified RECIST 1.1, which is described in detail below. (Eisenhauer E A et al. New response evaluation criteria in solid tumors: revised RECIST guideline (version 1.1).  European Journal of Cancer  45:228-247, 2009). 
     For subjects with non-measurable (non-target) disease only at baseline, SD was defined as those with non-CR/non-PD combined response. The primary endpoint of the study was to assess the proportion of subjects with clinical benefit (PCB) at 6 months (CR+PR+SD) in subjects with AR-positive breast cancer. 
     Secondary Endpoints 
     The secondary efficacy endpoints include: 
     To assess the clinical benefit in all subjects with breast cancer treated with Formula IX. The clinical benefit is defined as the proportion of subjects with complete response [CR]+ partial response [PR]+ stable disease [SD] as measured by modified RECIST 1.1 (Eisenhauer E A et al. New response evaluation criteria in solid tumors: revised RECIST guideline (Version 1.1).  European Journal of Cancer  45: 228-247, 2009). 
     For subjects with non-measurable (non-target) disease only at baseline, SD was defined as those with non-CR/non-PD combined response. 
     To assess objective response rate (ORR) in subjects with breast cancer treated with Formula IX. Objective response rate is defined as the proportion of subjects with a CR or PR at 6 months as measured by modified RECIST 1.1. For subjects with non-measurable (non-target) disease only at baseline, ORR is defined as the proportion of subjects with a CR at 6 months as measured by modified RECIST 1.1. 
     To assess progression free survival (PFS) in subjects with breast cancer treated with Formula IX. PFS is defined as the time elapsed between treatment initiation and tumor progression as measured by modified RECIST 1.1 OR death. 
     To assess time to progression (TTP) in subjects with breast cancer treated with Formula IX. Time to tumor progression is defined as the time elapsed between treatment initiation and tumor progression as measured by modified RECIST 1.1. 
     To assess duration of response in subjects with breast cancer treated with Formula IX. 
     To assess incidence of skeletal related events (SREs) in subjects treated with Formula IX. 
     To assess time to first skeletal related event (SRE) in subjects treated with Formula IX. 
     Tertiary Endpoints 
     To assess serum CA 27-29 changes in subjects with breast cancer treated with Formula IX. 
     To assess serum PSA changes in subjects with breast cancer treated with Formula IX 
     To assess changes in bone turnover markers (serum osteocalcin, serum collagen type I cross linked C-telopeptide [CTX], serum collagen type I cross linked N-telopeptide [NTX], serum bone specific alkaline phosphatase, and urinary NTX in subjects treated with Formula IX. 
     To assess the effect of Formula IX on quality of life (QOL) as measured by FACIT-F questionnaire in subjects treated with Formula IX. 
     To assess the effect of Formula IX on libido as measured by female sexual function index (FSFI) questionnaire in subjects treated with Formula IX. 
     To explore the relationship of various levels of AR expression as determined by immunohistochemistry with primary, secondary and tertiary objectives. 
     Results 
     After a median follow-up of 81 days (d) (range 7-304 d), preliminary results of the 22 patients were as follows: 9 SD was observed as best response, median duration 212 d. Current disposition of all patients: 15 PD after a median 80 d (range 15-304 d), 4 SD, and 3 early discontinuations (d 7, 28, 255). Among patients who reached 6 m, six are AR-positive with SD and increased PSA. 1 has yet to reach 6 m and no CR or PR has been observed. Formula IX was well-tolerated, with no drug related serious adverse events and none exceeding Grade 3. 
     No useful trends were seen with the biomarkers of bone turnover: bone specific alkaline phosphatase, C-telopeptides, N-telopeptides, and osteocalcin. Likewise breast cancer biomarker CA 27-29 did not demonstrate any useful trends. 
     PSA levels appeared to increase in response to Formula IX treatment as was observed in 20 of the 22 patients measured, but correlation with clinical benefit or disease progression is not yet evident. 
     The following non serous adverse events were observed: 
     A-fib(1); anxiety/emotional changes (5), arthralgia (6), bloating (2), bruising (1), cellulitis (1), chills (1), constipation (2), cough (1), dehydration (1), diarrhea (3), dizziness (2), dysgeusia (1), dyspepsia (1), dyspnea (3), edema (2), fatigue (14), fever (1), flatulence (1), glaucoma (1), headache (4), hot flash night sweats (7), hypertension (2), infection (1), insomnia (2), myalgia (5), nail discoloration (1), nausea (11), pain (22), paresthesia (1), pleural effusion (1), polyuria (1), post menopausal bleeding (3), rash/acne (3), stiffness (1), tendonitis (1), vision changes (3), vomiting (2), weight gain (2), and weight loss (2). 
     The liver enzymes (ALT, AST and bilirubin) returned to baseline with no interruption of therapy and no increase in total bilirubin. 
     Conclusions: Formula IX demonstrated promise as a novel targeted therapy for AR-positive MBC. The primary endpoint was achieved, with 6/17 AR-positive patients meeting statistical threshold for success. Serum PSA appeared to be a surrogate marker for AR activity and disease response.

Subjects 03, 07, 08, 11, 14, 16, 18, 19 and 22 were assessed as having clinical benefit as their best response (9 of 22 total subjects). Subjects with clinical benefit at Day 168 (6 months which was the clinical endpoint) were 03, 08, 14, 16, 18, and 19 (6 of 19 AR-positive subjects). Subject 11 was missing a metastasis biopsy and hence could not be counted toward the primary endpoint. Subject 22 has not yet reached the 6 month (day 168) on study date such that she could be counted toward the primary endpoint.            
Modified RECIST 1.1
 
     The modified RECIST 1.1 definitions described below was applied: 
     Measurable Lesions 
     A measurable lesion is defined as one lesion whose longest diameter (LD) can be accurately measured as ≥10 mm CT or MRI technique by using a 5 mm contiguous reconstruction algorithm. 
     Measurable lesions must be at least 2 times the slice thickness or at least two times the size of the CT scan interval cut. 
     Lesions seen on chest x-ray but not confirmed by CT or MRI scan are not acceptable as measurable lesions for this study. 
     To be considered pathologically enlarged and measurable, a lymph node must be &gt;15 mm in short axis when assessed by CT scan (CT scan slice thickness recommended to be no greater than 5 mm). At baseline and in follow-up, only the short axis will be measured and followed. 
     Measurable disease is defined as the presence of at least one measurable lesion. 
     All measurements will be taken and recorded in millimeters using an electronic measurement method. 
     Non-Measurable Lesions 
     Non-measurable lesions are defined as any lesion(s) that are smaller than the criteria for measurable lesions stated above (non-nodal lesions with longest diameter&lt;10 mm or pathological lymph nodes with ≥10 mm to &lt;15 mm in short axis) or truly non measurable lesions (or sites of disease). Lesions considered to be truly non-measurable are bone lesions (lytic lesions or mixed lytic-blastic lesions without identifiable soft tissue components, and blastic lesions), leptomeningeal disease, ascites, pleural/pericardial effusions, lymphangitis cutis/pulmonis, inflammatory breast disease, abdominal masses not confirmed by imaging techniques, and cystic lesions. 
     Target Lesions 
     Target lesions must be measurable lesions. 
     All target lesions up to a maximum of two lesions per organ and five lesions in total, representative of all involved organs, will be selected/confirmed as target lesions, recorded and measured at baseline. 
     Target lesions should be selected on the basis of their size (lesions with the longest diameter) and their suitability for accurate repetitive measurements by CT/MRI imaging techniques and be most representative of the subject&#39;s tumor burden. 
     Target lesions will be measured in one dimension by the size estimation of their diameter. A sum of the diameters (longest for non-nodal lesions and shortest for nodal lesions) for all target lesions will be calculated and reported for each time point. The baseline sum of diameters will be used as reference to further characterize the objective tumor response of the measurable dimension of the disease. 
     Non-Target Lesions 
     All other lesions (or sites of disease) and any measurable lesions that were not selected as target lesions) should be identified as non-target lesions and indicated as present at baseline. 
     Measurements of the non-target lesions may be performed, however the continued presence or absence as well as the disappearance or progression status of these lesions will be noted throughout follow-up assessments. 
     New Lesions 
     New lesions will be called at follow-up visits regardless of whether they occur in anatomic regions that were routinely subjected to follow-up, or in regions without disease at baseline and for which a follow-up scan is performed for clinical suspicion of new disease. New lymph nodes need to have a minimum size of 10 mm in their shortest axis. New non-nodal lesions need not to be measurable or to have a minimum size. Measurements of new lesions may be performed. 
     Response Criteria Definitions 
     The following response criteria will be applied for target and non-target lesions: 
     Target Lesion Response Criteria 
     Complete Response (CR): Disappearance of all target lesions. Target lymph node lesions that become &lt;10 mm in their shortest diameter will be considered to be normal (non-pathologic) and their actual measurement will be recorded. Thus, it follows that if all target node lesions have become &lt;10 mm, and all other non-nodal lesions have disappeared (whether target or non-target type), the overall response will be considered to be a CR. 
     Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of the diameters. 
     Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD taking as reference the smallest sum of diameters (nadir). 
     Progressive Disease (PD): At least a 20% increase in the sum of the diameters of target lesions taking as reference the smallest sum of diameters (nadir) recorded since the treatment started. In addition to the relative increase of 20%, the sum of diameters must also demonstrate an absolute increase of at least 5 mm 
     Not evaluable (NE): NE can be applied if repeated measurements cannot be assessed for reasons such as inadequate or missing imaging. 
     Non-Target Lesion Response Criteria 
     Complete Response (CR): Disappearance of all non-target lesions. All lymph nodes must be non-pathological in size (&lt;10 mm short axis). Disappearance of bone lesions identified on bone scintigraphy. 
     Non-CR/Non-PD: Persistence of one or more non-target lesions. Stability, decrease, or mild increase in uptake of bone lesions on bone scintigraphy. 
     Progressive Disease (PD): Unequivocal progression of existing non-target lesions. A perceived increase in bone disease in a preexisting area will not be considered progression. For bone scintigraphy, at least two new lesions are required to conclude to a definite presence of new lesions unless one or more of these lesions are confirmed by radiography, CT or MRI. 
     Not Evaluable (NE): NE can be applied if repeated evaluations cannot be assessed for reasons such as inadequate or missing imaging. 
     Definitions of Combined Response at Each Time Point 
     Determination of an overall response for each time point is based on the combination of responses for target, non-target, and the presence or absence of new lesions using the algorithm outlined on tables C1 and C2 below.

     Synthesis of (2R)-3-Bromo-N-[4-cyano-3-(trifluoromethyl)phenyl]-2-hydroxy-2-methylpropanamide 
     Thionyl chloride (46.02 g, 0.39 mol) was added dropwise to a cooled solution (less than 4° C.) of R-18 (51.13 g, 0.28 mol) in 300 mL of THF under an argon atmosphere. R-18 is (R)-3-bromo-2-hydroxy-2-methylpropanoic acid was prepared as described in Example 10. The resulting mixture was stirred for 3 h under the same condition. To this was added Et 3 N (39.14 g, 0.39 mol) and stirred for 20 min under the same condition. After 20 min, 5-amino-2-cyanobenzotrifluoride (40.0 g, 0.21 mol), 400 mL of THF were added and then the mixture was allowed to stir overnight at room temperature. The solvent was removed under reduced pressure to give a solid which was treated with 300 mL of H 2 O, extracted with EtOAc (2×400 mL). The combined organic extracts were washed with saturated NaHCO 3  solution (2×300 mL) and brine (300 mL). The organic layer was dried over MgSO 4  and concentrated under reduced pressure to give a solid which was purified from column chromatography using CH 2 Cl 2 /EtOAc (80:20) to give a solid. This solid was recrystallized from CH 2 Cl 2 /hexane to give 55.8 g (73.9%) of (2R)-3-bromo-N-[4-cyano-3-(trifluoromethyl)phenyl]-2-hydroxy-2-methylpropanamide (R-19) as a light-yellow solid.

     In order to determine whether compounds of this invention are agonists in breast cancer cells, HEK-293 or MDA-MB-231 cells were transfected with 0.25 μg GRE-LUC, 10 ng CMV-renilla LUC, and 25 ng CMV-hAR using lipofectamine Twenty four hours after transfection, the cells were treated with DHT, compound of Formula VIII or compound of Formula IX and luciferase assay was performed 48 hrs after transfection. Competitive binding of DHT, compound of Formula VIII and compound of Formula IX were measured using an in vitro competitive radioligand binding assay with [17α-methyl- 3 H]-mibolerone ([ 3 H]MIB), a known steroidal and high affinity AR ligand, and purified AR-LBD protein. 
     Results 
     DHT, compound of Formula VIII and Formula IX are agonists of AR in breast cancer cells as presented in  FIG. 13A-13C  (HEK-293 cells in  FIG. 13A  and MDA-MB-231 cells in  FIGS. 13B-13C ). The relative binding affinities (RBAs) for AR of DHT, Formula IX, Formula VIII, and bicalutamide were 1.0, 0.330, 0.314, and 0.016, respectively, demonstrating high affinity AR binding for the SARM compounds of this invention (data not shown).

     Inhibition of Intratumoral Gene Expression 
     AR agonists differentially regulate genes in ER-positive and ER-negative breast cancer cells. MDA-MB-231 and MCF-7 cells infected with AR or GFP containing adenovirus were maintained in charcoal stripped serum containing medium for 3 days and were treated with DHT or Formula VIII. After overnight treatment, the cells were harvested, RNA isolated and real-time PCR for the indicated genes were performed. The expression of various genes in response to either DHT or Formula VIII were measured and normalized to GAPDH, and are presented as composite data (same effects for DHT and Formula VIII) in Table 2.

     Gene Expression Array of MDA-MD-231-AR Xenograft 
     RNA was extracted from MDA-MB-231-AR tumors (n=5/group) treated with vehicle or compound of Formula VIII. RNA was pooled and Affymetrix microarray was performed to determine the change in expression of gene signature. 
     Results 
     The results presented in  FIG. 15  show that activation of AR in MDA-MB-231-AR xenografts suppressed the expression of more genes than it induced in these tumors. This pattern is unique in breast cancer cells and is different from gene expression results observed in prostate cancer cells, where more genes are induced than repressed (data not shown). 
     The results presented in  FIG. 16  validate the microarray results presented in  FIG. 15  by analyzing selected genes using realtime PCR TaqMan primers and probe in ABI 7900.

     Formula VIII Inhibits the Growth of MCF-7-AR Xenograft 
     MCF-7 cells stably transfected with AR using lentivirus were implanted (2 million cells/mouse; n=5) in nude mice that were ovariectomized and supplemented with estradiol (50 μg/day). Once tumors reached 100-200 mm 3 , the animals were randomized and treated with vehicle or 30 mg/kg per day of Formula VIII. Tumor volumes and body weights were measured thrice weekly. At the end of 5 weeks of treatment, the animals were sacrificed, tumors weighed and stored for RNA and protein isolation and histology. * significance at P&lt;0.05. 
     In addition, uterus weights were measured in these xenograft studies, and Western blot from MCF-7 tumor xenografts were probed for AR. 
     Results 
     The graph presented in  FIG. 17  demonstrates inhibition of triple-positive breast cancer (ER, PR, and HER2) using Formula VIII. The results show that Formula VIII inhibited the growth of MCF-7 breast cancer cell xenografts by greater than 50%. 
     The results presented in  FIG. 18  show Formula VIII inhibited uterus weight in these estrogen supplemented animals. 
     The results presented in  FIG. 19  demonstrate that the AR expression pattern in response to agonist (Formula VIII) is similar to that observed in prostate cancer cells (data not shown).

     Formula VIII Up-Regulates JNK Phosphorylation in MCF7-AR Tumors 
     Protein from MCF-7-AR tumors that were treated with vehicle or compound of Formula VIII were extracted and incubated with phospho MAPK array to determine the effect of compound of Formula VIII on phosphorylation of various kinases. 
     Results 
     The results presented in  FIG. 21  show that JNK phosphorylation is upregulated in MCF-7-AR tumors by treatment with compound of Formula VIII. JNK plays a critical role in death receptor-mediated intrinsic and extrinsic apoptotic pathways. JNK activates apoptotic signaling by up-regulating pro-apoptotic genes. The observed phosphorylation of the pro-apoptotic kinase, JNK, may be suggestive of a possible mechanistic explanation of the anti-proliferation.

     Gene Expression Analysis of MDA-MB-231-AR and MCF-7-AR Xenografts Following Treatment with Formula VIII and Formula IX 
     Microarray Analysis was performed on RNA from MDA-MB-231-AR and MCF-7-AR tumors in order to identify and compare changes in gene expression in ER-negative (MDA-MB-231-AR; triple negative) an ER-positive (MCF-7-AR; triple positive) breast cancer tumors treated with a compound of Formula VIII (30 mg/kg/day p.o. for 4 weeks). Affymetrix analysis of the xenografts was done on pooled samples of the xenografts. The analysis included ˜70,000 sequences with ˜30,000 genes and variations thereof represented, as well as microRNA&#39;s. RNA was isolated and expression of genes was evaluated using microarray (Affymetrix Human Gene ST 2.0 array). Expression of genes in compound of Formula VIII-treated samples was compared with the expression in vehicle-treated samples. Genes that were up- or down-regulated by more than 2 fold were considered differentially regulated by compound of Formula VIII.

     Of particular interest was that of the 1547 regulated genes identified in MCF-7-AR tumors and the 1536 regulated genes identified in MDA-MB-231-AR tumors, the subset of overlapping genes was only 245 genes. This result indicated that Formula VIII regulated distinct sets of genes in MCF-7-AR (ER-positive; triple positive) and MDA-MB-231-AR (ER-negative; triple negative) breast cancer cells. 
     Tables 4 and 5 below present genes involved in mammary tumorigenesis that were differentially regulated (by at least 2 fold) by Formula VIII in MDA-MB-231-AR tumors (Table 4) and MCF-7-AR tumors (Table 5). Indications of up-regulation or down-regulation are presented in the right-most column.

     The results presented in Tables 3 and 4 show that SARM treatment (Formula VIII) caused net down-regulation of genes in MDA-MB-231-AR tumors (N=1042 suppressed; N=640 induced; threshold of 2-2.5-fold increase or decrease (note: plot is log of fold change; follow-up RT-PCR demonstrated 10-20-fold changes). Well known androgen-dependent genes (e.g. FKPS and MUC1; See Table 6 below) were elevated, showing SARM penetration into the tumor. Also 29/36 known breast cancer-related genes were shown to be decreased, supporting a rational basis for the anti-proliferation activity of Formula VIII in ER-negative breast cancer. 
     Further analysis of the results in MDA-MB-231-AR tumors showed that Formula VIII induced known androgen-responsive genes (Table 6 below). Thus, breast cancer relevant genes such as beta2-adrenergic receptor and PARP1 were suppressed by Formula VIII; whereas ARE-dependent genes were induced by treatment of Formula VIII.

     The results presented in Tables 3 and 5 show that Formula VIII did not have as strong of a gene suppressive tone in MCF-7-AR triple positive (ER-positive) tumors as in triple negative (ER-negative) tumors. Interestingly though, the MCF-7-AR analysis showed that androgen-dependent genes were up regulated and estrogen-dependent genes were suppressed (Table 7 below), as validated by RT-PCR.

     The results presented in  FIG. 22  show inhibition of triple negative breast cancer growth using Formulae VIII and IX. Formula VIII and Formula IX demonstrated ˜85% TGI at all doses tried (5, 10 mg per kg for Formula VIII; 5, 10, 30 mg per kg for Formula IX) in the triple negative breast cancer model using MDA-MB-231-AR cells in nude mice. 
     The results presented in  FIG. 23  demonstrate inhibition of triple negative breast cancer using Formulae VIII and IX. Tumor weights were likewise reduced for all doses of Formula VIII and Formula IX. Spleen enlargement (680 mg vs. 200-300 mg for normal mice) was seen only in vehicle treated mice, possibly indicative of prevention by the SARMs of tumor metastasis to the spleen. 
     The in vitro data shown in MCF-7 cells with and without AR ( FIGS. 25A-25E ) support that SARM-activated AR may sequester the co-factors that are used by ER. Adding AR to the MCF-7 cells increased the effect of estradiol (when unopposed) on the ER target genes PR and PS2, but the antagonism caused by SARM alone or SARM+estradiol (E2) was enhanced in this setting ( FIGS. 25B and 25D ) as compared to GFP (i.e. no AR;  FIGS. 25A and 25C ).  FIG. 25E  shows that AR target genes are enhanced by SARM even in the presence of estradiol. 
     EXAMPLE 22 
     Xenograft Experiment with Formula IX 
     Xenograft Experiment. 
     NSG mice obtained from JAX labs were housed with five animals per cage and were allowed free access to tap water and commercial rat chow (Harlan Teklad 22/5 rodent diet—8640). During the course of the study, the animals were maintained on a 12 hr light:dark cycle. Animals were anesthetized and BR-0001 TNBC fragments of 1 mm 3  (approximately) were implanted subcutaneously in NSG mice. Once the tumor size reached 100-200 mm 3 , the animals were randomized and treated with vehicle control (polyethylene glycol:DMSO 9:1 ratio) or 10 mg/kg/day Formula IX (n=12) or enzalutamide orally. Tumor volume was measured thrice weekly. Tumor volume was calculated using the formula length×width×width×0.5236. Once tumors reached greater than 1500-2000 mm 3 , animals were sacrificed and tumors weighted and stored for various analysis. Two regions of the same BR-0001 tumor, an AR-positive TNBC xenograft, were immunohistochemically stained with AR antibody (AR N20 from SCBT) ( FIGS. 26A and 26B ) and compared to an AR-negative ( FIG. 26C ) TNBC as a negative control.  FIGS. 26A and 26B  show that AR expression is consistent throughout this formalin-fixed, paraffin-embedded (FFPE) tissue, whereas similar FFPE in AR-negative TNBC demonstrated no staining (no AR expression). The tumor xenograft efficacy experimental results are provided in  27 A- 27 C, with  FIGS. 27A and 27B  being replicate experiments. 
     EXAMPLE 23 
     Ki-67 Staining was Reduced in Tumors of Animals Treated with Formula IX 
       FIGS. 28A-28B  demonstrated an approximately 50% reduction in Ki-67 staining in 2 weeks of treatment. Tumors from replicate experiment 2 ( FIG. 27B ) were fixed in formalin and paraffin embedded. Slides were cut and stained with Ki-67 antibody. Ki-67 positive cells (total 200 cells were counted in each slide) in each slide were counted and represented as % stained cells, as shown in  FIG. 28B . Ki-67 staining was reduced in tumors of the animals treated with Formula IX. 
     EXAMPLE 24 
     Gene Expression Study and ChIP-Seq Study in Tumor Xenografts 
     Methods 
     Chromatin Immunoprecipitation Assay (ChIP). 
     Proteins were cross-linked by incubation with 1% formaldehyde (final concentration) at 37° C. for 10 min Tumors were homogenized using a probe hand-held homogenizer. The cells were washed with 1×PBS twice, scraped in 1 mL of PBS containing protease inhibitors ([1 mg each of aprotinin, leupeptin, antipain, benzamidine HCl, and pepstatin/m1], 0.2 mM phenylmethylsulfonyl fluoride, and 1 mM sodium vanadate), pelleted, and resuspended in SDS lysis buffer (1% SDS, 10 mM EDTA, 50 mM Tris-HCl [pH 8.1]). 
     After lysis on ice for 10 min, the cell extract was sonicated (Branson sonifier 250) in a cold room eight times for 10 s each at constant duty cycle, with an output of 3 and with incubation on ice after every sonication. The debris was pelleted at 13,000 rpm for 10 min at 4° C., and the supernatant was diluted 10-fold with ChIP dilution buffer (0.01% SDS, 1.1% Triton X-100, 1.2 mM EDTA, 16.7 mM Tris HCl [pH 8.1], 167 mM NaCl). The proteins were precleared with 50 μL of 1:1 protein A-Sepharose beads in TE. An aliquot (300 μL) was reserved as input, while the remaining solution was incubated with 5 μg of AR antibody (AR N20 SCBT) and 2 μg of sheared salmon sperm DNA (Stratagene, La Jolla, Calif.) rotating overnight at 4° C. 
     The protein-DNA-antibody complex was precipitated by incubating with 100 μL of 1:1 protein A-Sepharose beads and 2 μg of salmon sperm DNA at 4° C. for 2 h. The beads were pelleted and washed three times with low-salt wash buffer (0.1% sodium dodecyl sulfate [SDS], 1% Triton X-100, 2 mM EDTA, 20 mM Tris HCl [pH 8.1], 0.15 M NaCl), and twice with 1× TE (10 mM Tris HCl, 1 mM EDTA; pH 8.0). DNA-protein complexes were obtained by extracting the beads with 50 μL of freshly prepared extraction buffer (1% SDS, 0.1 M NaHCO 3 ) three times. Cross-linking of the DNA protein complexes was reversed by incubating at 65° C. for 6 h. The DNA was extracted with a QIAquick PCR purification kit (QIAGEN, Valencia, Calif.) in 25 μL final volume of TE. The purified DNA was given to University of Tennessee Health Science Center Molecular Resource Center (UTHSC MRC) for next generation sequencing using ion proton sequencer. 
     RNA Analysis and Microarray. 
     Tumors were homogenized, RNA isolated, purified and submitted to the UTHSC MRC core facility for microarray analysis (ST2.0 array from Affymetrix). 
     Results 
     In the gene expression study described above, RNA was isolated from the TNBC tumors and the expression of genes in the entire genome was measured by microarray (Affymetrix, ST2.0 array). In the ChIP-Seq study, chromatin immunoprecipitation was performed in untreated BR-0001 specimen and the DNA immunoprecipitated with AR antibody was sequenced using ion torrent next-generation sequencer. It was shown that ˜20% of AR-occupied promoters (−5 kb to +1 kb) were activated by androgen (mRNA increased by &gt;1.5 fold) (data not shown). Androgen treatment primarily affected cell cycle and metabolic process according to gene set enrichment analysis (GSEA) ( FIG. 31 ). Expression of TNBC subtype markers in  FIGS. 30A and 30B  show that in the SARM-treated tumors, gene markers for LAR and MSL subtypes are highly expressed. 
     Gene expression data was compared to PAM50 to determine the tumor type that BR-0001 belonged to. The expression (Z-score) of 50 genes required to classify the breast cancer is given in  FIG. 29 , in which PAM50 indicated that the tumor belonged to basal-like breast cancer (BLBC) TNBC. 
     Triple-negative breast cancer (TNBC) is a heterogeneous breast cancer group, and identification of its subtypes is essential for understanding the biological characteristics and clinical behaviors of TNBC as well as for developing personalized treatments. Based on 3,247 gene expression profiles from 21 breast cancer data sets, six TNBC subtypes, including 2 basal-like (BL1 and BL2), an immunomodulatory (IM), a mesenchymal (M), a mesenchymal stem-like (MSL), and a luminal androgen receptor (LAR) subtype from 587 TNBC samples with unique gene expression patterns and ontologies, were discovered (Brian D. Lehman et al., J. Clin. Invest. 2011, 121(7), 2750-2767). Cell line models representing each of the TNBC subtypes also displayed different sensitivities to targeted therapeutic agents. Gene expression data was compared to the genes published (Pietenpol group) to classify the BLBC into sub-classification.  FIGS. 30A-30B  depict that Pietenpol classification of TNBC suggests that the BR-0001 tumor is LAR and MSL subtypes. 
     EXAMPLE 25 
     Gene Expression Changes in Xenograft Tumors 
       FIG. 31  demonstrates that in BR-0001 Formula IX up-regulated gene expression. Approximately 4200 genes were up-regulated by Formula IX compared to vehicle, while approximately 1170 genes were down-regulated by Formula IX compared to vehicle. Formula IX recruited AR to 176 promoters (−5 kb to +1 kb). 20% of the promoters occupied by the AR in response to Formula IX also had the gene up-regulated by Formula IX. This showed that these genes were direct targets of the AR rather than an indirect effect. The Ingenuity Pathway Analysis (http://www.ingenuity.com/; QIAGEN, Redwood City, Calif.) suggests that genes involved in cell cycle were altered by Formula IX. 
     EXAMPLE 26 
     The Efficacy and Safety of Formula IX on Metastatic or Locally Advanced ER+/AR+ Breast Cancer (BC) in Postmenopausal Women 
     Study Design: 
     This is an open label, multicenter, multinational, randomized, parallel design Phase 2 study, and is to assess the efficacy and safety of Formula IX in postmenopausal subjects with ER+/AR+ BC. Subjects will be randomized to receive either Formula IX 9 mg or 18 mg given PO daily for up to 24 months. Each dose arm will be treated independently and each assessed for efficacy using Simon&#39;s two-stage (optimal) design (Simon R. Optimal two-stage designs for Phase 2 clinical trials.  Controlled Clinical Trials  1989; 10: 1-10). Subjects will be randomized in a 1:1 fashion to one of the two dose arms. 
     Randomization will be stratified by subjects presenting with bone only metastases and all other subjects, and further by setting of immediately preceding therapy (adjuvant setting or metastatic setting) in order to balance the proportion of subjects with these presenting features in each dose arm. There is no intent to statistically compare the two dose arms, but to determine whether either or both doses result in an acceptable clinical benefit response (CBR), defined as the proportion of evaluable subjects (i.e., subjects with centrally confirmed AR+ and who receive at least one dose of study drug) with either CR, PR, or SD by RECIST 1.1 at week 24, consistent with 30% while maintaining an acceptable safety profile. Given such a result, future exploration of Formula IX in ER+/AR+ BC would be warranted at that dose level. 
     Thirty-six to eighty-eight (36-88) subjects with centrally confirmed AR+ who receive at least one dose of study drug (evaluable subjects) will be needed for primary efficacy analysis purposes and will be a subset of the full analysis set (FAS). Thirty-six to one hundred and eighteen (36-118) subjects, including replacement subjects, will be randomized in a 1:1 fashion to receive a daily PO dose of either Formula IX 9 mg or 18 mg. Thirty of the aforementioned subjects may be considered replacement subjects to account for lack of centrally confirmed AR+ status or for the rare subject who is randomized but does not receive study drug (assumes 25% of enrolled subjects are not evaluable for the primary efficacy analysis). Other statistical parameters that are part of the sample size calculation are α=0.025 (one-sided) and power=90%. The first stage in each study arm will be assessed among the first 18 evaluable subjects. If at least 3/18 subjects achieve CB (defined as CR, PR, or SD) at week 24, the arm will proceed to the second stage of recruitment up to a total of 44 evaluable subjects per arm. Otherwise, the arm will be discontinued for lack of efficacy. Statistical significance, i.e., rejection of the null hypothesis of an unacceptably low CBR of ≤10% in favor of the alternative hypothesis that indicates the higher rate, ≥30%, is more likely, will be declared if at least 9/44 subjects achieve CB at week 24 in that arm. 
     Subjects who are not centrally confirmed AR+ may remain on the trial, but will not be part of the primary efficacy analysis—these subjects will contribute to secondary and tertiary analyses. 
     Subjects on the 18 mg treatment arm who experience an adverse event (AE) with Grade≥3 intensity (National Cancer Institute-Common Terminology Criteria for Adverse Events [NCI-CTCAE], Version 4.0) and/or intolerance may have a dose reduction from 18 mg to 9 mg per day or a drug interruption based on the medical judgment of the Investigator and after confirmation by the study Medical Monitor. The drug interruption may last for a period of up to 5 days after which the subject must be rechallenged with study drug (18 mg or 9 mg) or discontinued from the study. In the case of a dose reduction, once the AE has resolved or reduced in intensity to Grade 1, the subject may be rechallenged with 18 mg or maintained at 9 mg at the discretion of the Investigator. 
     Subjects on the 9 mg treatment arm who experience an AE with Grade≥3 intensity (NCI-CTCAE 4.0) and/or intolerance may have a drug interruption based on the medical judgment of the Investigator and after confirmation by the study Medical Monitor. The drug interruption may last for a period of up to 5 days after which the subject must be rechallenged with study drug (9 mg) or discontinued from the study. 
     For safety analysis, subjects will be analyzed in the treatment arm in which they are initially dosed. For efficacy analysis, subjects will be analyzed according to the treatment arm to which they were randomized 
     The subjects who demonstrate CB will be treated for up to 24 months from the date of randomization (as long as they continue to demonstrate CB from the treatment during these 24 months). Subjects who continue to demonstrate a CB from the study treatment at 24 months will be offered to continue in a safety extension study under a separate protocol. For safety purposes, all subjects will be followed-up for one month after the last dose of Formula IX is received. 
     For safety purposes, all subjects will be followed-up for one month after the last dose of Formula IX is received. 
     Target Population: 
     Adult postmenopausal women with metastatic or recurrent locally advanced ER+/AR+ BC. 
     Study Duration: 
     The study duration is estimated at 3 years. 
     Description of Agent or Intervention: 
     Three (3) Formula IX 3.0 mg softgels for a 9 mg daily dose or six (6) Formula IX 3.0 mg softgels for an 18 mg daily dose will be taken PO with water at approximately the same time each day, with or without food. 
     Potential Benefits: 
     Formula IX 9 mg once daily has been studied in 22 postmenopausal women with metastatic ER+ BC who have previously responded to hormonal therapy. The primary endpoint was assessed in 17 AR-positive subjects. Six of these 17 subjects demonstrated CB (SD) at six months. In one subject with SD (RECIST 1.1), tumor regression of 27% in a single target lesion was demonstrated. Seven subjects in total (one subject with indeterminate AR status) achieved CB at six months. Among the seven subjects who achieved CB at six months, time to progression (TTP) was estimated as 10.2 months. The results also demonstrated that, after a median duration on study of 81 days, 41 percent of all subjects (9/22) achieved CB as best response and also had increased PSA, which appears to be an indicator of AR activity. As of the finalization of this protocol, the study is still ongoing with one subject whose disease remains stable beyond 336 days. 
     Preclinical data with Formula IX suggests that it is also anabolic in bone and decreases bone turn over markers. Treatment with Formula IX may decrease bone turn over as compared with other hormonal therapies for the treatment of hormone receptor positive BC. Stronger bone microenvironment may decrease metastases to bone or delay time to skeletal related events. 
     Efficacy Objectives 
     The primary efficacy objective of this trial is to estimate the CBR at 24 weeks (defined as complete response [CR], partial response [PR], or SD) (by RECIST 1.1) of Formula IX 9 mg and of Formula IX 18 mg given PO daily in subjects with estrogen receptor positive and androgen receptor positive (ER+/AR+) BC who have centrally confirmed AR+ status. 
     The Secondary efficacy objectives are to estimate the CBR at 24 weeks (by RECIST 1.1) of Formula IX 9 mg and 18 mg in all subjects randomized who receive at least one dose of study medication (the full analysis set [FAS]) regardless of AR status as determined by the central laboratory. 
     The additional secondary efficacy objectives apply to both centrally confirmed AR+ subjects (the evaluable subset of the FAS) as well as to all subjects in the FAS: (a) Estimate the objective response rate (ORR; defined as CR or PR) (by RECIST 1.1) of Formula IX 9 mg and 18 mg at 24 weeks; (b) Estimate the best overall response rate (BOR) of Formula IX 9 mg and 18 mg; (c) Estimate the progression free survival (PFS) of subjects receiving Formula IX 9 mg and 18 mg; (d) Estimate the TTP of subjects receiving Formula IX 9 mg and 18 mg; and (e) Estimate duration of response (time from documentation of tumor response to disease progression or death) of subjects receiving Formula IX 9 mg and 18 mg. 
     The tertiary objectives apply to both centrally confirmed AR+ subjects (the evaluable subset of the FAS) as well as to all subjects in the FAS (a) Assess the effect of Formula IX 9 mg and 18 mg on serum PSA; (b) Assess the effect of Formula IX 9 mg and 18 mg on Quality of Life (QoL) as measured by EQ-5D-5L; (c) Assess the effect of Formula IX 9 mg and 18 mg on circulating tumor cells (CTCs); (d) Assess the impact of duration of prior CB on outcome; (e) Assess the impact of time from diagnosis of metastases to randomization on outcome; (f) Describe the effect of Formula IX 9 mg and 18 mg on tumor volumetrics; (g) Assess the effect of plasma concentrations of Formula IX and Formula IX glucuronide on CBR at 24 weeks. 
     The safety objective is to describe the safety profile of Formula IX 9 mg and 18 mg PO daily in subjects with ER+/AR+ BC with centrally confirmed AR+ as well as in all subjects randomized and treated. 
     The pharmacokinetic objective: To describe the plasma concentrations of Formula IX and Formula IX glucuronide at each of the assessed time points. 
     Formulation, Packaging, and Labelling: 
     Formula IX 3.0 mg Softgels will be supplied as opaque, white to off-white, size 5, oval Softgel capsules containing 3.0 mg of Formula IX. The liquid Softgel fill is composed of Formula IX dissolved in polyethylene glycol 400. Formula IX 3.0 mg Softgels will be packaged in blister packs. Each blister pack will contain sufficient study drug for one (1) week of dosing. At randomization (Visit 2) and at Visits 3, 4, and 5), subjects will be provided with a carton of study drug containing 7 blister packs, equivalent to 7 weeks of dosing. At Visits 6, 8, 9, 10, 11, 12, and 13, in order to accommodate the visit schedule of every 12 weeks (±7 days), the subjects will receive two carton boxes of study drug (each containing 7 blisters) to cover study treatment for 14 weeks. Subjects will be requested to bring with them the carton box with all blister packs at every visit. 
     Each blister pack will be comprised of an appropriate number of blister strips (1 blister for the 9 mg treatment arm and 2 blisters for the 18 mg treatment arm) encased in a child-resistant heat-sealed card. The blister strips are composed of a PVC/ACLAR base and an aluminum foil/PVC/PVAC copolymer and polymethacrylate (product contact) lidding. Perforations on the back of the heat-seal card overlay the foil lidding. To remove the study drug, subjects will release the appropriate perforation by depressing a release button on the inside of the card. Once released, the perforation can be removed and the study drug pushed through the foil. 
     Pharmacokinetic Assessment: 
     Blood samples for pharmacokinetic assessment will be collected at baseline (pre-dose), Visit 3 (week 6), Visit 5 (week 18), and Visit 6 (week 24). One blood sample will be collected in a 6 mL K 2 -ethylenediaminetetraacetic acid (EDTA) blood collection tube on each of these days. The exact time (hh:mm) and date that each blood sample is collected will be recorded on the electronic Case Repot Form. At the baseline visit, the blood sample should be collected before the subject is given their first dose of Formula IX. At Visits 3 (week 6), 5 (week 18), and 6 (week 24), the date and approximate time of the last dose of Formula IX prior to the blood sample should be recorded; i.e., it should be documented whether the subject took the previous dose that morning or the evening before Immediately after collection, the tubes will be gently inverted several times to mix the anticoagulant with the blood sample. 
     Blood samples will be kept on wet ice (ice packs in a water bath is also acceptable) for up to 20 minutes until processed. The plasma fraction will be separated by placing the collection tube into a centrifuge for 10 minutes at 1,500×g. The plasma fraction will be withdrawn by pipette and divided into two 2 mL polypropylene transfer vials (with each tube receiving approximately equal aliquots). 
     All sample collection and freezing tubes will be clearly labeled in a fashion which identifies the subject, the study number, the visit number, and freezing tube aliquot letter. Labels will be fixed to freezing tubes in a manner that will prevent the label from becoming detached after freezing. Samples will be stored in a freezer at −20° C. or lower. Samples will be shipped in a thermal insulated container with sufficient dry ice to assure they remain frozen. 
     Any remaining plasma samples after completion of the protocol outlined pharmacokinetic analysis may be used to identify and quantify the metabolites of Formula IX.

     The 18 mg Dose: 
     Formula IX has been evaluated in 21 completed and ongoing clinical studies enrolling over 1,500 total subjects. Formula IX has been generally well-tolerated, including single doses up to 100 mg and multiple doses up to 30 mg once daily for up to 14 days. In longer studies, Formula IX has also been generally well tolerated, including 1, 3, and 9 mg daily doses for up to 184 days. 
     Previous clinical studies demonstrated that daily doses up to 30 mg of Formula IX were well tolerated in healthy male volunteers. Both 10 mg and 30 mg daily doses were evaluated in Protocol G100402 for up to 14 days. Elevated alanine transaminase (ALT) (any elevation outside upper limit of normal [ULN]) was the most common adverse event (AE) experienced. None of the subjects in the 10 mg dose group were discontinued from the study due to ALT elevations. In the 30 mg dose group, six subjects experienced ALT increases above two times the ULN. 
     Formula IX 3 mg given daily was evaluated in two completed Phase 3 trials, in over 600 subjects, for the prevention and treatment of muscle wasting (cachexia) in subjects with advanced non-small cell lung cancer receiving chemotherapy. Formula IX 3 mg increased lean body mass in both studies and was safe and well tolerated when dosed for up to 168 days. Subjects in the Formula IX and placebo groups experienced similar AEs and these AEs were consistent with the background chemotherapy regimen. 
     Although Formula IX 3 mg was chosen for its anabolic activity in muscle for the completed Phase 3 program, a dose of 9 mg once daily was selected for hormonal therapy in the ongoing Phase 2 trial in ER+ and AR+ metastatic breast cancer in order to achieve a higher exposure that is both safe and more likely to be efficacious in women with advanced breast cancer. Seven out of twenty-two subjects with advanced, heavily pretreated (hormonal therapy, radiation, and chemotherapy) breast cancer demonstrated clinical benefit (CB) (stable disease [SD]) at 6 months. In one subject with SD (by Response Evaluation Criteria in Solid Tumors [RECIST], Version 1.12), tumor regression of 27% was demonstrated. Consistent with the previous studies, Formula IX remained safe and well tolerated (see Example 9). 
     Reductions in sex hormone binding globulin (SHBG) have been identified as one of the most sensitive serum biomarkers for AR signaling in healthy volunteers and patients. SHBG was reduced by 15.1%, 15.6%, 18.2%, and 18.4% in young, healthy volunteers who received PO Formula IX 1 mg, 3 mg, 10 mg, and 30 mg daily for 14 days, respectively, in Protocol G100402 (listed as trial #2 above), suggesting that doses of 10 mg and above maximally stimulate AR activity. 
     Dosing Formula IX at 15-20 mg per day may provide therapeutic benefit in hormone receptor positive breast cancer by two separate mechanisms: activating AR and inhibiting progesterone receptor, thereby increasing potential efficacy. Progesterone receptor expression in cancer stem cells has been shown to be involved in proliferation of cancer epithelial cells, and inhibiting progesterone receptor&#39;s activity is now considered a novel approach to treating breast cancer. Hence, Formula IX at higher doses might provide dual anti-proliferative effects in breast cancer. In TNBC, doses of 15-20 mg per day should provide saturation of the AR potentially providing better efficacy as opposed to a lower dose with partial occupancy of the AR and absence of any progesterone receptor inhibitory effect. 
     Based on the safety data collected to date in both preclinical and clinical settings, the 18 mg dose is expected to be safe and generally well tolerated. However, in the event that a subject has a Grade 3 or greater toxicity, the 18 mg dose may be reduced to 9 mg until the AE resolves or for the remainder of treatment based on the Investigator&#39;s discretion. The 9 mg dose has been previously studied in postmenopausal women with metastatic breast cancer and was safe and well tolerated. 
     In TNBC patients, the 18 mg dose is preferred over a lower dose due to the aggressive phenotype of the disease and poor prognosis. Based on preclinical data, the 18 mg dose is more likely to saturate the AR and may lead to better clinical outcomes than a lower dose without receptor saturation or progesterone receptor inhibition. 
     The 18 mg dose may provide greater efficacy in TNBC without compromising subject safety. However, in the event that a subject has a Grade 3 or greater toxicity, the 18 mg dose may be reduced to 9 mg until the AE resolves or for the remainder of treatment based on the Investigator&#39;s discretion. The 9 mg dose has been previously studied in postmenopausal women with metastatic breast cancer and was safe and well tolerated. 
     In TNBC patients, the 18 mg dose is preferred over a lower dose due to the aggressive phenotype of the disease and poor prognosis. Based on preclinical data, the 18 mg dose is more likely to saturate the AR and may lead to better clinical outcomes than a lower dose without receptor saturation or progesterone receptor inhibition. 18 mg dose may provide greater efficacy in TNBC without compromising subject safety. 
     Study Design: 
     This is an open label, multicenter, multinational, Phase 2 study to assess the efficacy and safety of Formula IX in female subjects with androgen receptor-positive, triple negative breast cancer (AR+ TNBC). Subjects will be administered Formula IX, 18 mg orally (PO) daily for up to 12 months. Simon&#39;s two-stage (optimal) design will be used to assess primary efficacy and will require up to 41 evaluable subjects; i.e., subjects with centrally confirmed AR+ who receive at least one dose of study drug. In order to obtain these numbers of evaluable subjects, 21 to 55 subjects, including over-enrollees (see below), will be enrolled to receive a daily PO dose of GTx-024 18 mg. Fourteen of the aforementioned subjects may be over-enrollees to allow for replacement of subjects to account for lack of centrally confirmed AR+ status, or for the rare subject who is enrolled but does not receive study drug. The trial will test for an unacceptably low clinical benefit rate (CBR) of ≤5% versus a CBR more consistent with ≥20%. The first stage will be assessed among the first 21 evaluable subjects. If at least 2/21 subjects achieve clinical benefit (CB) (defined as complete response [CR], partial response [PR], or stable disease [SD], per Response Evaluation Criteria in Solid Tumors [RECIST], Version 1.12) at week 16, then the trial will proceed to the second stage of recruitment of up to a total of 41 subjects in the evaluable subset of the Full Analysis Set (FAS). Otherwise, the trial will be discontinued for lack of efficacy. 
     Subjects who are not confirmed AR+ may remain on the trial, but will not be part of the primary efficacy analysis—these subjects will contribute to secondary and tertiary analyses. Subjects who experience an adverse event (AE) with Grade≥3 intensity (National Cancer Institute Common Terminology Criteria for Adverse Events [NCI-CTCAE], Version 4.0) and/or intolerance may have a dose reduction from 18 mg to 9 mg per day or a drug interruption based on the medical judgment of the Investigator and after confirmation by the study Medical Monitor. The subjects who demonstrate clinical benefit (CB) will be treated for up to 12 months from the date of the first dose of study treatment (as long as they continue to demonstrate CB from the treatment during these 12 months). Subjects who continue to demonstrate a beneficial response from the study treatment at 12 months will be offered to continue in a safety extension study under a separate protocol. All subjects will be followed-up for one month after the last dose of Formula IX is received, for safety purposes. 
     Primary efficacy objective of this trial is to estimate the clinical beneficial rate (CBR) at 16 weeks (defined as complete response (CR), partial response (PR), or stable disease (SD)) (by RECIST 1.1) of Formula IX 18 mg given orally (PO) daily in subjects with TNBC and centrally confirmed AR+ status. 
     Secondary Efficacy Objectives: 
     Estimate the CBR at 16 weeks of Formula IX 18 mg in all subjects enrolled who receive at least one dose of study medication (i.e., the full analysis set (FAS)) regardless of AR status as determined by the central laboratory. 
     The following secondary efficacy objectives apply to both centrally confirmed AR+ subjects (the evaluable subset of the FAS) as well as to all subjects in the FAS:
         Estimate the objective response rate (ORR; defined as CR or PR) (by RECIST 1.1) of Formula IX 18 mg at 16 weeks.   Estimate the CBR of Formula IX 18 mg at 24 weeks.   Estimate the ORR (defined as CR or PR) of Formula IX 18 mg at 24 weeks.   Estimate the best overall response rate (BOR) of Formula IX 18 mg.   Estimate the progression free survival (PFS) of subjects receiving Formula IX 18 mg.   Estimate the time-to-progression (TTP) of subjects receiving Formula IX 18 mg.   Estimate duration of response (time from documentation of tumor response to disease progression or death) of subjects receiving Formula IX 18 mg.       

     Tertiary Objectives: 
     The following tertiary efficacy objectives apply to both centrally confirmed AR+ subjects (the evaluable subset of the FAS) as well as to all subjects in the FAS:
         Assess the effect of Formula IX 18 mg on serum prostate specific antigen (PSA).   Assess the effect of Formula IX 18 mg on Quality of Life (QoL) as measured by EQ-5D-5L.   Assess the effect of Formula IX 18 mg on circulating tumor cells (CTCs).   Assess the impact of duration of prior CB on outcome.

     EXAMPLE 28 
     Formula IX Reduced the Growth of HER2-Positive Tumors 
     Methods 
     HCI-007 tumor pieces (1 mm 3 ) were implanted surgically (one per mouse) under the skin on the flanks of NSG mice. Simultaneously, estradiol pellet (Innovative Research of America) was implanted surgically under the skin of each mouse. Tumors were allowed to grow and reach approximately 100 mm 3  volume (1*W*W*0.526). Mice were randomized and treated orally with vehicle (15% DMSO+85% PEG-300), Formula IX (10 mg/kg), or enzalutamide (20 mg/kg). Tumor volume was measured weekly and represented as % change in tumor volume ( FIG. 32 ). Mice were sacrificed and tumors stored for further analysis. 
     Results 
     As described in  FIG. 32 , ER-positive, PR-positive, HER2-positive and AR-positive tumors of animals treated with vehicle and enzalutamide grew comparably, while the tumors of mice treated with Formula IX grew slowly. Tumors of animals treated with Formula IX regressed during the first 7 days, before started to slowly increase. 
     Conclusion 
     These results support the previous results observed in MCF-7 cells xenograft demonstrating that Formula IX reduced the growth of HER2-positive tumors. 
     EXAMPLE 29 
     Formula IX Inhibits Growth in HCI-013 Patient Derived Xenografts that are Triple Positive (ER, PR, HER2), and Also Express AR 
     Methods 
     HCI-013 tumor pieces (1 mm 3 ) were implanted surgically (one per mouse) under the skin on the flanks of NSG mice. Tumors were allowed to grow and reach approximately 100 mm 3  volume (1*W*W*0.526). Mice were randomized and treated orally with vehicle (15% DMSO+85% PEG-300) or Formula IX (10 mg/kg). Tumor volume was measured weekly and represented as % change in tumor volume. Mice were sacrificed, tumors weighed, and stored for further analysis. 
     Results 
     As described in  FIGS. 33A and 33B , triple positive HER2 tumors of animals treated with vehicle grew robustly, while the tumors of mice treated with Formula IX grew very slowly. Tumors of Formula IX treated animals did not grow appreciably through the duration of the experiment suggesting that there is almost a 100% tumor growth inhibition (TGI) ( FIG. 33A ). The tumor volume results are reflected in tumor weights observed at the end of the experiment ( FIG. 33B ). 
     Conclusion 
     These results indicate that Formula IX is extremely potent in tumors that are triple positive (express ER, PR, and HER2) and also express AR.
