[0002] This invention relates to the prevention and treatment of obesity. More particularly, this invention relates to a method of a) treating, preventing, suppressing, inhibiting, or reducing obesity; b) promoting, increasing or facilitating weight loss; c) decreasing, suppressing, inhibiting or reducing appetite; d) altering the body composition; e) altering lean body mass or fat free body mass; f) converting fat to lean muscle; g) treating, preventing, suppressing, inhibiting, or reducing an obesity-associated metabolic disorder, for example hypertension, osteoarthritis, Type II diabetes mellitus, increased blood pressure, stroke, or heart disease; h) decreasing, suppressing, inhibiting or reducing adipogenesis; i) altering stem cell differentiation; and/or j) altering the level of leptin; comprising administering a therapeutically effective amount of a selective androgen receptor modulator and/or its analog, derivative, isomer, metabolite, pharmaceutically acceptable salt, pharmaceutical product, hydrate, N-oxide, prodrug, polymorph, crystal, or any combination thereof.

BACKGROUND OF THE INVENTION

[0003] Obesity is not only a nutritional disorder in Western societies, it is also a serious health concern because of its association with adult-onset diabetes, hypertension, and heart disease (Grundy, 1990, Disease-a-Month 36:645-696). In addition, obesity is currently described by World Health Organization (WHO) as an epidemic in many industrialized nations. While there is evidence to suggest that body weight was physiologically regulated, the molecular mechanism has remained elusive. However, animal studies have produced several mouse strains that contain single-gene mutations, resulting in an obese phenotype. One such recessive mutation is manifested in the ob/ob mice, and it is referred to as the obese (ob) mutation.

[0004] The ob gene product, (also known as Leptin), is a major adipocyte-derived hormone that is involved in the regulation of food intake and energy expenditure.

[0005] In an effort to understand the physiologic function of the ob gene, several independent research groups produced recombinant ob gene product in bacteria for in-vivo testing (Pelleymounter et al., 1995, Science 269:540-543; Halaas et al., 1995, Science 269:543-546; Campfield et al., 1995, Science 269:546-549). When the Ob protein (also known as leptin) was injected into grossly obese mice, which possessed two mutant copies of the ob gene, the mice exhibited a reduced appetite and began to lose weight. In addition, these studies described a dual action of leptin in both reducing the animals' food intake and in increasing their energy expenditure. Similarly, when normal mice received leptin, they also ate less than the untreated controls. More importantly, Campfield et al. (1995, Science 269:546-549) injected leptin directly into lateral ventricle, and observed a reduction in the animals' food intake, suggesting that leptin acts on central neuronal networks to regulate feeding behavior and energy balance. Thus, this result provides evidence that the leptin receptor (also known as OB-R) is expressed by cells in the brain. Additionally, several studies have shown that ob gene expression is actually increased in obese humans (Considine et al., 1995, J. Clin. Invest. 95:2986-2988; Lonnquist et al., 1995, Nature Med. 1:950; Hamilton et al., 1995, Nature Med. 1:953).

[0006] Since leptin is effective at controlling weight loss, food intake, and energy expenditure, modulating and/or controlling the levels of leptin is a useful therapeutic approach in treating preventing, inhibiting or reducing the incidence of obesity in subjects suffering from obesity. Controlling the level of leptin may result in a loss of appetite, a reduction of food intake, and an increase in energy expenditure in the subject, and thus may contribute to the control and treatment of obesity.

[0007] Obesity, if left unabated, can have dire health consequences, such as adult-onset diabetes (Type II diabetes), hypertension, heart disease, osteoarthritis, increased blood pressure, increased incidence of stroke, and accelerated morbidity and mortality. Innovative approaches are urgently needed at both the basic science and clinical levels to treat obesity.

[0195] Biological Activity of Selective Androgen Receptor Modulator Compounds

[0196] Selective androgen receptor modulator (SARM) compounds are a novel class of androgen receptor targeting agents (“ARTA”), that have previously been shown to be useful for a) male contraception; b) treatment of a variety of hormone-related conditions, for example conditions associated with Androgen Decline in Aging Male (ADAM), such as fatigue, depression, decreased libido, sexual dysfunction, erectile dysfunction, hypogonadism, osteoporosis, hair loss, anemia, obesity, sarcopenia, osteopenia, osteoporosis, benign prostate hyperplasia, alterations in mood and cognition and prostate cancer; c) treatment of conditions associated with Androgen Decline in Female (ADIF), such as sexual dysfunction, decreased sexual libido, hypogonadism, sarcopenia, osteopenia, osteoporosis, alterations in cognition and mood, depression, anemia, hair loss, obesity, endometriosis, breast cancer, uterine cancer and ovarian cancer; d) treatment and/or prevention of acute and/or chronic muscular wasting conditions; e) preventing and/or treating dry eye conditions; f) oral androgen replacement therapy; g) decreasing the incidence of, halting or causing a regression of prostate cancer; and/or h) inducing apoptosis in a cancer cell.

[0197] As demonstrated herein, it has surprisingly been discovered that SARM compounds are also useful for a) treating, preventing, suppressing, inhibiting, or reducing obesity; b) promoting, increasing or facilitating weight loss; c) decreasing, suppressing, inhibiting or reducing appetite; d) altering the body composition; e) altering lean body mass or fat free body mass; f) converting fat to lean muscle; g) treating, preventing, suppressing, inhibiting, or reducing an obesity-associated metabolic disorder, for example hypertension, osteoarthritis, Type II diabetes mellitus, increased blood pressure, stroke, or heart disease; h) decreasing, suppressing, inhibiting or reducing adipogenesis; i) altering stem cell differentiation; and/or j) altering the level of leptin; comprising administering a therapeutically effective amount of a selective androgen receptor modulator and/or its analog, derivative, isomer, metabolite, pharmaceutically acceptable salt, pharmaceutical product, hydrate, N-oxide, prodrug, polymorph, crystal, or any combination thereof, as described herein.

[0198] As demonstrated herein, the SARM compounds of the present invention alter the levels of leptin in a subject. In another embodiment, the SARM compounds decrease the levels of leptin and are therefore inhibitors of leptin. In another embodiment, the SARM compounds of the present invention increase the levels of leptin in a subject. As described above, leptin was shown to have an effect on appetite on weight loss in obese mice, and thus has been implicated in obesity (Pelleymounter et al., 1995, Halaas et al., 1995, Campfield et al., 1995). When leptin was injected into grossly obese mice, which possessed two mutant copies of the ob gene, the mice exhibited a reduced appetite and began to lose weight. In addition, leptin played a role in reducing the animals' food intake and in increasing their energy expenditure. Similarly, when normal mice received leptin, they also ate less than the untreated controls. Moreover, it has been suggested by Campfield et al that leptin acts on central neuronal networks to regulate feeding behavior and energy balance.

[0199] As used herein, the term ‘leptin inhibitor’ refers to a SARM compound which decreases the level of leptin, so that the level of leptin after treatment with the SARM compound is lower than the level of leptin in the absence of the compound. As used herein ‘increasing the level of leptin’ means that the levels of leptin after treatment with the SARM compound is higher than the level of leptin in the absence of the SARM compound. In one embodiment, the term ‘level of leptin’ refers to the serum level of leptin. As contemplated herein, the SARM compounds of the present invention have an effect on leptin in-vitro and in-vivo. Leptin levels can be measured by methods known to one skilled in the art, for example by commercially available ELISA kits. In addition, Leptin levels may be determined in in-vitro assays, or in in-vivo assays, by any method known to a person skilled in the art.

[0200] Since leptin is implicated in controlling appetite, weight loss, food intake, and energy expenditure, modulating and/or controlling the levels of leptin is a useful therapeutic approach in treating preventing, inhibiting or reducing the incidence of obesity in subjects suffering from obesity. Modulating the level of leptin can result in a loss of appetite, a reduction of food intake, and an increase in energy expenditure in the subject, and thus may contribute to the control and treatment of obesity.

[0201] The term “obesity” is defined as an increase in body weight beyond the limitation of skeletal and physical requirement, as the result of excessive accumulation of fat in the body.

[0202] The term “obesity-associated metabolic disorder” means a disorder which results from, is a consequence of, is exacerbated by or is secondary to obesity. Non-limiting examples of such a disorder are osteoarthritis, Type II diabetes mellitus, increased blood pressure, stroke, and heart disease.

[0203] The term “osteoarthritis” refers to anon-inflammatory degenerative joint disease occurring chiefly in older people, characterized by degeneration of the articular cartilage, hypertrophy of bones and the margins and changes in the synovial membrane. It is accompanied by pain and stiffness, particularly after prolonged activity.

[0204] The term “diabetes” means a relative or absolute lack of insulin leading to uncontrolled carbohydrate metabolism. Most patients can be clinically classified as having either insulin-dependent diabetes mellitus (IDDM or Type-I diabetes) or non-insulin-dependent diabetes mellitus (NIDDM or Type-II diabetes).

[0205] The term “increased blood pressure” or “hypertension” refers to a repeatedly high blood pressure above 140 over 90 mmHg. Chronically high blood pressure can cause blood vessel changes in the back of the eye, thickening of the heart muscle, kidney failure, and brain damage.

[0206] The term “stroke” refers to damage to nerve cells in the brain due to insufficient blood supply often caused by a bursting blood vessel or a blood clot. The term “heart disease” refers to a malfunction in the heart normal function and activity, including heart failure.

[0207] In addition, androgens have recently been shown to be involved in commitment of mesenchymal pluripotent cells into myogenic lineage and to block differentiation into adipogenic lineage (Singh et al., Endocrinology, Jul. 24, 2003). Accordingly, selective androgen receptor modulator compounds can be useful in methods of blocking adipogenesis, and/or altering stem cell differentiation, as described herein.

[0208] The term “adipogenesis”, also referred to as “lipogenesis”, refers to the production of fat, either fatty degeneration or fatty infiltration, and also covers the normal deposition of fat or the conversion of carbohydrate or protein to fat.

[0209] The term “stem cell” refers to a cell that gives rise to a lineage of cells. In the process of stem cells differentiation, these cells divide to produce dissimilar daughter cells, one replacing the original stem cell, the other differentiating further to different lineages of cells.

[0210] As contemplated herein, the SARMs which are useful in preventing and treating obesity are classified as androgen receptor agonists (AR agonists) or androgen receptor antagonists (AR antagonists).

[0211] The AR is a ligand-activated transcriptional regulatory protein that mediates induction of male sexual development and function through its activity with endogenous androgens (male sex hormones). The androgenic hormones are steroids which are produced in the body by the testis and the cortex of the adrenal gland. Androgenic steroids play an important role in many physiologic processes, including the development and maintenance of male sexual characteristics such as muscle and bone mass, prostate growth, spermatogenesis, and the male hair pattern (Matsumoto, Endocrinol. Met. Clin. N. Am. 23:857-75 (1994)). The endogenous steroidal androgens include testosterone and dihydrotestosterone (“DHT”). Other steroidal androgens include esters of testosterone, such as the cypionate, propionate, phenylpropionate, cyclopentylpropionate, isocarporate, enanthate, and decanoate esters, and other synthetic androgens such as 7-Methyl-Nortestosterone (“MENT'”) and its acetate ester (Sundaram et al., “7 Alpha-Methyl-Nortestosterone(MENT): The Optimal Androgen For Male Contraception,” Ann. Med., 25:199-205 (1993) (“Sundaram”)).

[0212] A receptor agonist is a substance which binds receptors and activates them. A receptor antagonist is a substance which binds receptors and inactivates them. In one embodiment, the SARMs which are useful in treating and preventing obesity and which modulate leptin levels are AR agonists, and are, therefore, useful in binding to and activating the AR. In another embodiment, the SARMs which are useful in treating and preventing obesity and which modulate leptin levels are AR antagonists, and are, therefore, useful in binding to and inactivating the AR. 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 SARM compounds to maintain and/or stimulate the growth of AR containing tissue such as prostate and seminal vesicles, as measured by weight. AR antagonistic activity can be determined by monitoring the ability of the SARM compounds inhibit the growth of AR containing tissue.

[0213] In yet another embodiment, the SARM compounds of the present invention can be classified as partial AR agonist/antagonists. The SARMs are AR agonists in some tissues, to cause increased transcription of AR-responsive genes (e.g. muscle anabolic effect). In other tissues, these compounds serve as competitive inhibitors of testosterone/DHT on the AR to prevent agonistic effects of the native androgens.

[0214] The compounds of the present invention bind either reversibly or irreversibly to the androgen receptor. In one embodiment, the SARM compounds bind reversibly to the androgen receptor. In another embodiment, the SARM compounds bind irreversibly to the androgen receptor. The compounds of the present invention may contain a functional group (affinity label) that allows alkylation of the androgen receptor (i.e. covalent bond formation). Thus, in this case, the compounds bind irreversibly to the receptor and, accordingly, cannot be displaced by a steroid, such as the endogenous ligands DHT and testosterone.

[0215] As defined herein, “contacting” means that the SARM compound of the present invention is introduced into a sample containing the protein or enzyme 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 SARM to the enzyme. Methods for contacting the samples with the SARM 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.

The SARM compounds can also be administered intermittently, for example every other day, 3 days a week, four days a week, five days a week and the like.

[0220] As used herein, the term “treating” includes preventative as well as disorder remitative treatment. As used herein, the terms “reducing”, “suppressing” and “inhibiting” have their commonly understood meaning of lessening or decreasing.

[0223] In one embodiment, the pharmaceutical compositions are administered orally, and are thus formulated in a form suitable for oral administration, i.e. as a solid or a liquid preparation. Suitable solid oral formulations include tablets, capsules, pills, granules, pellets and the like. Suitable liquid oral formulations include solutions, suspensions, dispersions, emulstions, oils and the like. In one embodiment of the present invention, the SARM compounds are formulated in a capsule. In accordance with this embodiment, the compositions of the present invention comprise in addition to the SARM active compound and the inert carrier or diluent, a hard gelating capsule.

[0224] Further, in another embodiment, the pharmaceutical compositions are administered by intravenous, intraarterial, or intramuscular injection of a liquid preparation. Suitable liquid formulations include solutions, suspensions, dispersions, emulsions, oils and the like. In one embodiment, the pharmaceutical compositions are administered intravenously, and are thus formulated in a form suitable for intravenous administration.

In another embodiment, the pharmaceutical compositions are administered intramuscularly, and are thus formulated in a form suitable for intramuscular administration.

[0225] Further, in another embodiment, the pharmaceutical compositions are administered topically to body surfaces, and are thus formulated in a form suitable for topical administration. Suitable topical formulations include gels, ointments, creams, lotions, drops and the like. For topical administration, the SARM agents 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.

[0226] Further, in another embodiment, the pharmaceutical compositions are administered as a suppository, for example a rectal suppository or a urethral suppository. Further, in another embodiment, the pharmaceutical compositions are administered by subcutaneous implantation of a pellet. In a further embodiment, the pellet provides for controlled release of SARM agent over a period of time.

[0227] 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, N.Y., pp. 353-365 (1989); Lopez-Berestein, ibid., pp. 317-327; see generally ibid).

[0228] As used herein “pharmaceutically acceptable carriers or diluents” are well known to those skilled in the art. The carrier or diluent may be a solid carrier or diluent for solid formuations, a liquid carrier or diluent for liquid formulations, or mixtures thereof.

[0229] Solid carriers/diluents include, but are not limited to, a gum, a starch (e.g. corn starch, pregeletanized starch), a sugar (e.g., lactose, mannitol, sucrose, dextrose), a cellulosic material (e.g. microcrystalline cellulose), an acrylate (e.g. polymethylacrylate), calcium carbonate, magnesium oxide, talc, or mixtures thereof.

[0230] For liquid formulations, pharmaceutically acceptable carriers may be aqueous or non-aqueous solutions, suspensions, emulsions or oils. Examples of non-aqueous solvents are propylene glycol, polyethylene glycol, and injectable organic esters such as ethyl oleate. Aqueous carriers include water, alcoholic/aqueous solutions, emulsions or suspensions, including saline and buffered media. Examples of oils are those of petroleum, animal, vegetable, or synthetic origin, for example, peanut oil, soybean oil, mineral oil, olive oil, sunflower oil, and fish-liver oil.

[0231] Parenteral vehicles (for subcutaneous, intravenous, intraarterial, or intramuscular injection) include sodium chloride solution, Ringer's dextrose, dextrose and sodium chloride, lactated Ringer's and fixed oils. Intravenous vehicles include fluid and nutrient replenishers, electrolyte replenishers such as those based on Ringer's dextrose, and the like. Examples are sterile liquids such as water and oils, with or without the addition of a surfactant and other-pharmaceutically acceptable adjuvants. 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. Examples of oils are those of petroleum, animal, vegetable, or synthetic origin, for example, peanut oil, soybean oil, mineral oil, olive oil, sunflower oil, and fish-liver oil.

[0232] In addition, the compositions may further comprise binders (e.g. acacia, cornstarch, gelatin, carbomer, ethyl cellulose, guar gum, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, povidone), disintegrating agents (e.g. cornstarch, potato starch, alginic acid, silicon dioxide, croscarmelose sodium, crospovidone, guar gum, sodium starch glycolate), buffers (e.g., Tris-HCI., acetate, phosphate) of various 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), protease inhibitors, surfactants (e.g. sodium lauryl sulfate), permeation enhancers, solubilizing agents (e.g., glycerol, polyethylene glycerol), anti-oxidants (e.g., ascorbic acid, sodium metabisulfite, butylated hydroxyanisole), stabilizers (e.g. hydroxypropyl cellulose, hyroxypropylmethyl cellulose), viscosity increasing agents(e.g. carbomer, colloidal silicon dioxide, ethyl cellulose, guar gum), sweetners (e.g. aspartame, citric acid), preservatives (e.g., Thimerosal, benzyl alcohol, parabens), lubricants (e.g. stearic acid, magnesium stearate, polyethylene glycol, sodium lauryl sulfate), flow-aids (e.g. colloidal silicon dioxide), plasticizers (e.g. diethyl phthalate, triethyl citrate), emulsifiers (e.g. carbomer, hydroxypropyl cellulose, sodium lauryl sulfate), polymer coatings (e.g., poloxamers or poloxamines), coating and film forming agents (e.g. ethyl cellulose, acrylates, polymethacrylates) and/or adjuvants.

[0233] In one embodiment, the pharmaceutical compositions provided herein are controlled release compositions, i.e. compositions in which the SARM compound is released over a period of time after administration. Controlled or sustained release compositions include formulation in lipophilic depots (e.g. fatty acids, waxes, oils). In another embodiment, the composition is an immediate release composition, i.e. a composition in which all of the SARM compound is released immediately after administration.

[0234] 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).

[0235] The compositions may also include incorporation of the active 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.

[0236] 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.

[0237] Also comprehended by the invention are 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. The modified compounds 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'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.

[0238] The preparation of pharmaceutical compositions which contain an active component is well understood in the art, for example by mixing, granulating, or tablet-forming processes. The active therapeutic ingredient is often mixed with excipients which are pharmaceutically acceptable and compatible with the active ingredient. For oral administration, the SARM agents 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. For parenteral administration, the SARM agents 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.

[0239] 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.

[0240] For use in medicine, the salts of the SARM will be pharmaceutically acceptable salts. Other salts may, however, be useful in the preparation of the compounds according to 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 according to 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.

[0241] In one embodiment, the methods of the present invention comprise administering a SARM compound as the sole active ingredient. However, also encompassed within the scope of the present invention are methods or treating obesity as disclosed herein, which comprise administering the SARM compounds in combination with one or more therapeutic agents. These agents include, but are not limited to: LHRH analogs, reversible antiandrogens, antiestrogens, anticancer drugs, 5-alpha reductase inhibitors, aromatase inhibitors, progestins, or agents acting through other nuclear hormone receptors.

[0242] Thus in one embodiment, the present invention provides compositions and pharmaceutical compositions comprising a selective androgen receptor modulator compound, in combination with an LHRH analog. In another embodiment, the present invention provides compositions and pharmaceutical compositions comprising a selective androgen receptor modulator compound, in combination with a reversible antiandrogen. In another embodiment, the present invention provides compositions and pharmaceutical compositions comprising a selective androgen receptor modulator compound, in combination with an antiestrogen. In another embodiment, the present invention provides compositions and pharmaceutical compositions comprising a selective androgen receptor modulator compound, in combination with an anticancer drug. In another embodiment, the present invention provides compositions and pharmaceutical compositions comprising a selective androgen receptor modulator compound, in combination with a 5-alpha reductase inhibitor. In another embodiment, the present invention provides compositions and pharmaceutical compositions comprising a selective androgen receptor modulator compound, in combination with an aromatase inhibitor. In another embodiment, the present invention provides compositions and pharmaceutical compositions comprising a selective androgen receptor modulator compound, in combination with a progestin. In another embodiment, the present invention provides compositions and pharmaceutical compositions comprising a selective androgen receptor modulator compound, in combination with an agent acting through other nuclear hormone receptors.

[0243] The following examples are presented in order to more fully illustrate the preferred embodiments of the invention. They should in no way, however, be construed as limiting the broad scope of the invention.

EXPERIMENTAL DETAILS SECTION

EXAMPLE 1

Effect of Compound VI and Compound VII on Organ Weights and Leptin Levels

[0244]

[0245] In recent pharmacological studies Applicants identified two SARMs (Compounds VI and VII) with high in vitro androgen receptor (AR) binding affinity and in vivo androgenic and anabolic activity. Since Compounds VI and VII show tissue-selective anabolic activity, these compounds were tested for their effects target organ weights and on levels of leptin, a fat biomarker that serves as a marker for anabolic effects and that has been implicated in obesity, in intact male rats after short-term and long-term drug treatment.

[0246] Methods:

[0247] Immature male Sprague-Dawley rats (195-205 gram body weight) were used for this study. Animals were divided into groups of 15 animals (5 animals per time point) to receive one of the following treatments: (1) vehicle control, (2) testosterone propionate dissolved in vehicle solution at a dose of 500 μg/day, (3) Compound VI at dose of 500 μg/day dissolved in vehicle solution, or (4) Compound VII at dose of 500 μg/day dissolved in vehicle solution. All doses were delivered by subcutaneous placement of Alzet osmotic pumps. Daily food intake was recorded for one-week and two-week studies.

[0248] Seven, 14 and 28 days after pump implantation, animals were exsanguinated under ketamine/xylazine anesthesia. Serum was collected, separated into 10 aliquots and stored at −80° C. Major organs were collected, weighed and stored at −80° C.

[0249] Serum concentrations of testosterone (T), leptin, Insulin and IGF-1 were determined by commercially available ELISA kits. Serum concentration of Compound VI and Compound VII were determined by HPLC.

[0250] Results:

[0251] The results of the Leptin experiments are shown in Table 1. Compared with the vehicle control, Compound VII decreased serum leptin levels by 36% (2 w) and 22% (4 w).

[0252] The observed changes in organ weight were consistent with previous studies by Applicants and confirmed the tissue-selective anabolic activity of Compound VI and Compound VII. Compound VII had a more profound effect on serum leptin concentrations, suggesting it may affect animal body composition and other endocrine systems, such as the hypothalamo-pituitary-IGF-1 axis and the reproductive axis.

EXAMPLE 2

Effect of Compound VI on Lean Body Mass and Percent Body Fat

[0253] Methods:

[0254] Two hundred and thirty (230) female Sprague-Dawley rats (23 weeks of age) were used in these studies.

[0255] Animals were randomized (n=10 per group) into each of the treatment groups outlined in Table 2 below. Animals assigned to groups 6 through 23 were ovariectomized on day 0 of the experiment.

[0256] Drug administration with Compound VI, bicalutamide (an antiandrogen), and/or DHT commenced on day 0 or 90 with the compound of interest administered via daily subcutaneous injection (0.20 mL) and continued until day 120 or 210 of the study. Drug solutions were prepared daily by dissolving in DMSO and dilution with PEG 300. The percentage of DMSO was the same in all vehicles (17.6%), as determined based on the solubility of the test compounds.

[0257] Whole body DEXA images were collected up to 120 or 210 days after ovariectomy, as described in Table 2. Lean body mass (LBM), fat mass (FM) and total body mass (TBM) were determined at each time point.

[0258] All animals were sacrificed on day 120 or 210. Femurs, tibias, and lumbar vertebrae were excised from the sacrificed rats for future studies. Left femurs, left tibias, and L2-L4 vertebrae were placed in 10% Formalin for 2 days following excision and then moved to 70% Alcohol and stored at 4° C. until histomorphometric analysis. Right femurs, right tibias, and L5-L6 vertebrae were stored at in saline soaked gauze at −20° C. until mechanical testing. Additionally, right femurs, right tibias, and the vertebral column were scanned by DEXA immediately following excision.

[0259] Nine and two days prior to sacrifice, animals were administered an i.p. injection of Calcein (10 mg/kg).
