Description

USE OF BIMATOPROST FREE ACID ADMINISTERED TO THE SKIN
TO REDUCE ADIPOSE TISSUE
Field of the Invention [0001] The present invention relates to methods and compositions for treating and/or preventing metabolic syndrome or a disorder associated with metabolic syndrome, e.g., obesity, dyslipidemia, and/or a diabetic condition, in the body of a subject. More specifically, obesity, dyslipidemia, and/or a diabetic condition may be treated and/or prevented by administering to a subject a therapeutically effective amount of one or more compounds described herein.
Background of the Invention

[0002] Metabolic syndrome, also known as metabolic syndrome X, cardiometabolic syndrome, syndrome X, and insulin resistance syndrome, is a cluster of medical disorders that, when occurring together, increase the risk of diabetes and cardiovascular disease. See, e.g., Alberti et al. Circulation 2009;120:1640-1645. Metabolic syndrome affects 35-40% of American adults, and prevalence increases with age. Principal disorders associated with or used in the diagnosis of metabolic syndrome include, but are not limited to, obesity, dyslipidemia, and diabetic conditions, and conditions associated with these disorders, such as elevated glucose levels and hypertension.

[0003] Obesity is a risk factor for a wide array of diseases, for example, type 2 diabetes, hypertension, hyperlipidemia, coronary artery disease, stroke, breast and colon cancer, sleep apnea, gall bladder disease, gastroesophogeal reflux disease, fatty liver disease, gout, and thromboembolism. Blood pressure, blood sugar, serum cholesterol, and serum uric acid are usually higher in obese people than in those of normal weight. Despite increased awareness of these health risks, the prevalence of obesity has risen steadily for decades in many industrialized nations. As a result, there has been considerable interest in ways to reduce obesity.

[0004] The excess body fat of obese subjects is typically deposited in adipose tissue.
This tissue and its principal cell type, the adipocyte, have been implicated in a wide array of diseases, for example, metabolic syndrome, type 2 diabetes, atherosclerosis, fatty liver. hepatic fibrosis, breast cancer, inflammation, depression, and dementia. The causative role of adipose tissue in these diseases appears to involve mediators such as adiponectin, resistin, tumor necrosis factor alpha (TNF¨a.), interleukin-6 (IL-6). C¨reactive protein (CRP), fibrinogen, plasminogen activator inhibitor-1 (PAI-1), and/or C¨terminal binding protein (CtBP). As a result, the adipocyte per se rather than being a mere storehouse for calories, plays a pathogenic role in many diseases and represents a target for therapeutic intervention.

[0005] A number of medical conditions are considered to be causes of obesity or local excesses of body fat. Examples include drug¨induced obesity, hypothyroidism, pseudohypoparathyroidism, hypothalamic obesity, polycystic ovarian disease, depression, binge eating, Prader¨Willi syndrome, Bardet¨Biedl syndrome, Cohen syndrome, Down syndrome, Turner syndrome, growth hormone deficiency, growth hormone resistance, leptin deficiency or resistance, HIV lipodystrophy, and Cushing syndrome and pseudo¨Cushing syndrome (i.e., characteristic syndrome of excess body fat and other findings due to excessive endogenous or exogenous corticosteroid levels). Some of these conditions, for example, Cushing syndrome, pseudo¨Cushing syndrome. and HIV¨related lipodystrophy, are associated with other features of metabolic syndrome, such as insulin resistance and dyslipidemia.

[0006] Medications known to cause obesity or local excess of body fat include cortisol and analogs, other corticosteroids, megace, sulfonylureas, antiretrovirals, tricyclic antidepressants, monoamine oxidase inhibitors, selective serotonin reuptake inhibitors, oral contraceptives, insulin, risperidone, clozapine, and thiazolidinediones. Some of these medications, for example, corticosteroids and antiretrovirals, are associated with other features of metabolic syndrome, such as insulin resistance and dyslipidemia.

[0007] Changes in hormonal status, including physiologic changes such as pregnancy or menopause, may result in obesity in a subject. Smoking cessation commonly leads to weight gain and obesity. Trauma may favor the accumulation of excess body fat by virtue of immobility or disuse of an extremity. Similar problems may affect an immobile subject, such as an astronaut or bedridden subject who is immobilized for an extended period of time. Some tumors, for example, lipomas, are characterized by collections of fat cells that may be amenable to methods to reduce body fat. Even in the absence of underlying pathology, a subject may have cosmetic concerns about body fat. These can usually be attributed to constitutional or hereditary factors, developmental history, age, gender, diet, alcohol use, or other aspects of lifestyle.

[0008] A number of methods have been developed to reduce obesity. It is helpful to classify these methods as extractive, metabolic, or adipolytic. Extractive methods, such as lipoplasty (e.g., liposuction) or local excision, are methods whereby fat is physically removed from areas of interest. Such methods do not appear to correct other features of metabolic syndrome. They are costly and may involve scars, postsurgical deformity or regression, discomfort, infection, and other adverse reactions.

[0009] In contrast to extractive methods, metabolic methods, which include medications, nutritional supplements, devices, bariatric surgery, and exercise or other body treatment, seek to modify the subject's metabolism (e.g., whether caloric intake, expenditure, or both) such that there is a net loss of fat in the subject. A disadvantage is potential concomitant loss of water, carbohydrates, protein, vitamins, minerals, and other nutrients. Furthermore, traditional diet medications may have undesired side effects, for example, palpitations, tremor, insomnia, and/or irritability in a subject who uses stimulants as appetite suppressants.
Drawbacks of surgery are mentioned above. Despite salubrious value, the traditional metabolic methods of diet and exercise are not practical for everybody.

[0010] Adipolytic methods aim to cause breakdown of adipocytes and/or their lipid contents. For example, fat deposits can be reduced by exposure to cold temperature or to deoxycholate, a solubilizer which lyses cell membranes and results in local necrosis. Drawbacks of these methods can include poor discrimination between adipose and other nearby tissues, barriers to delivery that require hypodermic needles or special equipment, and adverse effects such as necrosis, inflammation, and pain.

[0011] Fat circulates in the blood in various lipid and lipoprotein forms.
Common measures of lipid concentration in the blood include serum triglycerides, serum total cholesterol, serum low density lipoprotein ([DL), and serum high density lipoprotein (HDL).
These lipid concentrations are heavily influenced by diet and metabolism.

[0012] Dyslipidemia is an abnormality in one or more lipid or lipoprotein levels in the blood. Dyslipidemia comprises one or more of: elevated serum triglycerides, elevated total cholesterol, elevated low density lipoprotein (LDL), reduced hid density lipoprotein (HDL), and/or abnormal distribution of serum lipoproteins as measured, for example, by nuclear magnetic resonance spectroscopy.

[0013] Elevations of some lipid concentrations, e.g. triglycerides and/or LDL, are risk factors for diseases such as atherosclerosis, coronary heart disease, stroke, neurovascular disease, peripheral vascular disease, and diabetes. Conversely, abnormally low levels of HDL are associated with cardiovascular disease. Numerous medications have been developed to treat dyslipidemia, e.g., by reducing lipid and/or lipoprotein concentrations. Of these, the "statins" or HMG CoA reductase inhibitors, which decrease LDL levels, are well known examples. For many patients, however, the currently available therapies arc insufficient or unsuitable, for example, due to side effects such as myopathy.

[0014] Diabetic conditions include diabetes mellitus and pre¨diabetes.
Diabetes mellitus, which comprises type 1 diabetes and type 2 diabetes, is a condition characterized by hyperglycemia resulting from the body's inability to use blood glucose for energy. Pre¨diabetes is a condition wherein blood glucose levels are higher than normal but not high enough for a diagnosis of diabetes; people with pre¨diabetes are at increased risk for developing type 2 diabetes. A common feature of type 2 diabetes and pre¨diabetes, insulin resistance, is a physiological condition wherein insulin becomes less effective at lowering blood sugar levels, resulting in elevated blood sugar levels. Impaired glucose tolerance is a condition wherein glucose intake (for example, orally or intravenously) results in abnormally elevated blood sugar levels. Glucose tolerance can be measured, for example, by systematic challenge with an oral glucose load (oral glucose tolerance test). "Diabetic complications" include chronic and acute complications of diabetes. Chronic complications include atherosclerosis, stroke, myocardial ischemia, nephropathy, peripheral neuropathy, retinopathy, infection, foot ulcers, and death.
Acute complications include metabolic acidosis, nonketotic hypersosmolar state, volume depletion, coma, and death.

[0015] Local reduction of adipose tissue does not treat dyslipidemia or diabetes. The peer¨reviewed literature has even expressed concern that lysis of adipocytes could dump lipids into the bloodstream and thereby increase serum lipid concentrations. See, e.g., Klein et al, Lasers Surg Med 2009; 41:785-790. In one clinical trial, local reduction of flank fat by cryolipolysis did not cause any change in serum triglycerides, total cholesterol, LDL, or HDL
See, e.g., Klein et al, Lasers Surg Med 2009;41:785-790. Likewise, local reduction of hip fat by laser lipolysis caused no change in these parameters. See, e.g, Mordon eta!, J
Cosmet Laser Ther 2009;11:74-74. Furthermore, surgical removal of subcutaneous fat in hamsters actually increased serum triglyceride levels and insulin resistance due to compensatory deposition of intra¨abdominal. fat. See, e.g., Weber eta!, Am J Physiol Regul Integr Comp Physiol 2000;279:R936-943. Even large¨volume lipectomy, which is distinct from local fat reduction, does not consistently elicit a reduction in serum lipids or serum glucose. In one report, 9 of 10 patients who underwent large¨volume lipectomy showed reduced serum total cholesterol, but no reduction in triglycerides, or in the HDL:LDL ratio. See, e.g., Baxter, Aesthet Surg J
1997;17:213-215. Surgical lipectomy in Zucker rats showed mean reductions in serum triglycerides and total cholesterol, but no reductions in serum glucose. See, e.g., Liszka et al, Plast Reconstr Surg 1998;102:1122-1127.

[0016] Even systemic medical therapy for weight loss does not necessarily lead to absolute benefits in serum lipids or glucose. A landmark randomized controlled trial studied the effects of two years of systemic Orlistat therapy in obese adults. See Davidson et al, JAMA
1999;281:235-243. After two years, subjects randomized to Orlistat 120 ing three times daily lost 8.8% of baseline body weight, compared to 5.8% in the placebo group (p <
.001). However, this weight loss was not accompanied by any absolute improvement in serum lipids or serum glucose.
100171 Therefore, there is a need for new approaches including new methods and compositions for treating and/or preventing metabolic syndrome and associated conditions, for example, treating or preventing obesity, dyslipidemia, and/or diabetic conditions, in a subject in need thereof. These approaches may include reducing fat and/or adipocytes in the subject and optionally also reducing levels of undesired serum lipids and/or serum glucose in the bloodstream.
Summary of the Invention [0018] The present invention arises in part from a new finding that systemic administration of certain F¨series prostaglandins to obese, dyslipidemic, and/or diabetic subjects has a beneficial effect on the subjects. The effects observed in subjects systemically treated with such prostaglandins include reduced obesity, reduced weight gain, reduce serum triglycerides, reduced serum LDL, increased serum HDL, reduced serum glucose, and/or improved glucose =
tolerance.
[00191 The present invention also arises from the observation that systemic administration of certain F¨series prostaglandin compounds to obese subjects reduces weight of the subject and/or reduces weight gain in those subjects.

[0020] The present invention also arises from the identification of certain particularly useful species from among the genus of F¨series prostaglandins for the purposes of the invention.
[0021] U.S. Patent 7,666,912, contemplates non-systemic topical, subcutaneous, intramuscular, and intralesional administration of certain prostaglandins, e.g., bimatoprost, latanoprost, and tavoprost, would locally reduce fat in a subject at the site of administration. For instance, the Examples of U.S. Patent 7,666,912 contemplates non-systemic transdermal application of bimatoprost at concentrations of 0.003%, 0.03%, or 0.3%, would locally reduce fat in a subject at the site of administration. The inventor has now discovered that while 0.3%
topical bimatoprost locally reduces subcutaneous fat in a subject, the isopropyl ester and free acid of bimatoprost are significantly more effective in reducing subcutaneous fat. The inventor has further discovered that transdermal administration of bimatoprost at 0.3%
has no effect on systemic reduction of fat, while the corresponding free acid and isopropyl ester have dramatic systemic effects and systemic fat reduction. The inventor has further found that even higher doses, e.g., 0.7% dose of latanoprost, may be desirable in order to obtain systemic effects transdermally. Furthermore, the inventor discovered that neither subcutaneous nor intraaperitoneal administration of bimatoprost had any significant effect on fat reduction. The inventor contemplates that the observed benefits of transdermal administration may be similarly observed if a tune¨release formulation, such as a controlled or sustained release, for oral or subcutaneous administration is delivered. Other routes of administration for various time¨
release formulations are contemplated. These findings and observations, which are the basis for the present invention, are indeed surprising and unexpected, especially considering U.S. Patent 7,666,912 dissuades from systemically administering such compounds.

The foregoing aspects and embodiments of the invention may be more fully understood by reference to the following Definitions, Figures, Detailed Description, Examples, and the Claims.
Definitions Chemical definitions [0039] Definitions of specific functional groups and chemical terms are described in more detail below. The chemical elements are identified in accordance with the Periodic Table of the Elements, CAS version, Handbook of Chemistry and Physics, 75th Ed., inside cover, and specific functional groups are generally defined as described therein. Additionally, general principles of organic chemistry, as well as specific functional moieties and reactivity, are described in Organic Chemistry, Thomas Sorrell, University Science Books, Sausalito, 1999;
Smith and March March's Advanced Organic Chemistry, 51h Edition, John Wiley & Sons, Inc., New York, 2001; Larock, Comprehensive Organic Transformations, VCH Publishers, Inc., New York, 1989; and Carruthers, Some Modern Methods of Organic Synthesis, 3rd Edition, Cambridge University Press, Cambridge, 1987.
[0040] Certain compounds as described herein can comprise one or more asymmetric centers, and thus can exist in various isomeric forms, e.g., enantiomers and/or diastereomers.
The compounds provided herein can be in the form of an individual enantiomer, diastereomer or geometric isomer, or can be in the form of a mixture of stereoisomers, including racemic mixtures and mixtures enriched in one or more stereoisomer. In certain embodiments, the compounds as described herein are enantiopure compounds. In certain other embodiments, mixtures of stereoisomers are provided.
[0041] Furthermore, certain compounds, as described herein may have one or more double bonds that can eXist as either the cis or trans, or the E or Z isomer, unless otherwise indicated.
The invention additionally encompasses the compounds as individual isomers substantially free of other isomers, and alternatively, as mixtures of various isomers, e.g., racemic mixtures of E/Z
isomers or mixtures enriched in one E/Z isomer.
[0042] The terms "enantiomerically enriched," "enantiomerically pure" and "non¨racemic,"
as used interchangeably herein, refer to compositions in which the percent by weight of one enantiomer is greater than the amount of that one enantiomer in a control mixture of the racemic composition (e.g., greater than 1:1 by weight). For example, an enantiomerically enriched preparation of the (S)¨enantiomer, means a preparation of the compound having greater than 50% by weight of the (S)¨enantiomer relative to the (R)¨enantiomer, more preferably at least 75% by weight, and even more preferably at least 80% by weight. In some embodiments, the enrichment can be much greater than 80% by weight, providing a "substantially enantiomerically enriched," "substantially enantiomerically pure" or a "substantially non¨racemic" preparation, which refers to preparations of compositions which have at least 85% by weight of one enantiomer relative to other enantiomer, more preferably at least 90% by weight, and even more preferably at least 95% by weight. In preferred embodiments, the enantiomerically enriched composition has a higher potency with respect to therapeutic utility per unit mass than does the racemic mixture of that composition. Enantiomers can be isolated from mixtures by methods known to those skilled in the art, including chiral high pressure liquid chromatography (HPLC) and the formation and crystallization of chiral salts; or preferred enantiomers can be prepared by asymmetric syntheses.

[00761 Other definitions [0077] As used herein, the terms "salt", "acceptable salt", or "pharmaceutically acceptable salt" refer to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio.
Pharmaceutically acceptable salts are well known in the art. For example, S.
M. Berge et at., describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, I-19. Pharmaceutically acceptable salts of the compounds of this invention include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid and perchloric acid or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid or malonic acid or by using other methods used in the art such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hem isulfate, heptanoate, hexanoate, hydroiodide, 2¨hydroxy¨ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, inalate, maleate, malonate, methanesulfonate, 2¨naphthalenesulfonate, nicotinatc, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3¨phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p¨toluenesulfonate, undecanoate, valerate salts, and the like. Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and W(Cli¨ta1ky1)4 salts. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like.
Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate and aryl sulfonate.
[0078] As used herein, the term "prodrug" means a biologically active derivative of a compound that can hydrolyze, oxidize, or otherwise react under biological conditions (in vitro or in vivo) to provide the pharmacologically active compound. In this instance, the "prodrug" is a compound administered to a subject, and the pharmacologically active compound is the "active metabolite thereof." In certain cases, a prodrug has improved physical and/or delivery properties over the parent compound. Prodrugs are typically designed to enhance pharmaceutically and/or pharmacokinetically based properties associated with the parent compound. The advantage of a prodrug can lie in its physical properties, such as enhanced water solubility for parenteral administration at physiological pH compared to the parent compound, or it enhances absorption from across the skin, or it may enhance drug stability for long¨term storage.
[0079] "Metabolic syndrome" is a combination of medical disorders that, when occurring together, increas'es the risk of developing cardiovascular disease and diabetes. A recent joint scientific statement (Alberti, supra) requires the presence at least 3 of the following 5 findings:
elevated waist circumference (definition varies by country), elevated triglycerides (greater than or equal to 150 mg/dL). reduced HDL (under 40 mg/dL in males or under 50 mg/dL
in females), elevated blood pressure (systolic greater than or equal to 130 mm and/or diastolic greater than or equal to 85 mm Hg), and elevated fasting glucose (greater than or equal to 100 mg/dL).
Principal disorders associated with or used in the diagnosis of metabolic syndrome include, but are not limited to, obesity, dyslipidemia, and diabetic conditions, and conditions associated with these disorders, such as elevated glucose levels and hypertension.
[0080] As used herein, an "individual" or "subject" to which administration is contemplated includes, but is not limited to, humans (i.e., a male or female of any age group, e.g., a pediatric subject (e.g., child, adolescent) or adult subject (e.g., young adult, middle¨aged adult or senior adult)), other primates (e.g., cynomolgus monkeys, rhesus monkeys) and commercially relevant mammals such as cattle, pigs, horses, sheep, goats, cats, and/or dogs. In any aspect and/or embodiment of the invention, the subject is a human subject.

"an amount sufficient" or "sufficient amount" of a compound means the level, amount or concentration of the compound needed to treat or prevent metabolic syndrome and/or a disorder associated with metabolic syndrome, or to treat or prevent a particular parameter (e.g., body weight, body fat; adipocytes, lipid or glucose concentrations in the blood) in the body of a subject, without causing significant negative or adverse side effects to body or the treated tissue.
The term "therapeutically effective amount" can encompass an amount that improves overall therapy, reduces or avoids symptoms or causes of metabolic syndrome and/or a disorder associated with metabolic syndrome, or enhances the therapeutic efficacy of another therapeutically active agent.
[0082] As used herein, a "therapeutically effective concentration" refers to the concentration (e.g., ug/mL) of a compound, or active metabolite thereof, in the blood of a subject within the therapeutic range. The "therapeutic range" refers to the concentration above the minimal effective concentration (i.e., the required level of a compound needed for therapeutic effect) and below the minimum effective concentration for adverse effects (i.e., the toxic level of the compound).
[0083] As used herein, the terms "reduce", "reduction", "reducing", "lower", or "lowering"
means to diminish or lessen the volume, size, mass, bulk, density, amount, and/or quantity of a substance (e.g., body weight, body fat, adipocyte size, adipocyte number, adipose tissue volume, adipose tissue thickness, lipid concentration, glucose concentration) in the body of a subject.
[00841 As used herein, the term "eliminate" means to completely remove any unwanted or undesired volume, size, mass, bulk, density, amount, and/or quantity of a substance (e.g., excess body weight, excess body fat, excess adipocytcs, excess adipose tissue, elevated lipid concentration, elevated glucose concentration) in the body of a subject.
[0085] As used herein, "suffer", "suffers" or "suffering from" refers to a subject having metabolic syndrome and/or a disorder associated with metabolic syndrome. As used herein, "likely to suffer" refers to a subject who has not been diagnosed with metabolic syndrome and/or a disorder associated with metabolic syndrome by a medical practitioner, but has a predisposition (e.g., genetic and/or physiologic predisposition), or exhibits signs or symptoms of metabolic syndrome and/or a disorder associated with metabolic syndrome.

Brief Description of the Drawings 100881 Figure / depicts a randomized, controlled, repeat¨dose, 4¨week trial conducted on (db¨ldb¨) mice, which are defective for the leptin receptor (Jackson Laboratories). These mice are genetically obese, dyslipidemic. and diabetic. Mice were obtained from Jackson Laboratories and acclimated to the facility. At about 5 weeks of age, mice were prospectively randomized into'groups and assigned to the treatment conditions shown in Figure I. Topical treatments were applied in a thin film to the right flank skin without occlusive dressings;
subcutaneous injections were also administered to the right flank. Mice were observed for condition and weighed daily. They were housed in the same room, in II cages according to group, and fed ad libitum. Skin tissue was sampled and serum lipids tested on day 28. Tissue was fixed in formalin and stained with hematoxylin and eosin.
[0089] Figure 2 shows mean weight gain of the mice treated in Figure 1 for days 0 to 28, by group. Animals treated with vehicle only (Groups 1 and 2) showed an expected amount of weight gain for the strain (normative data, Jackson Laboratories). Transdermal bimatoprost isopropyl ester (BIE) and bimatoprost free acid (BFA) reduced weight gain significantly and in a dose¨dependent manner, but topical bimatoprost did not. Subcutaneous BIE, subcutaneous BFA, and intraperitoneal BFA had no significant effect on weight gain.
[0090] Figure 3 shows representative histologic sections of skin and subcutaneous fat from untreated (left) and treated (right) flanks of animals assigned to vehicle only (Group 1), topical bimatoprost 0.3% (Group 4), and topical BIE 0.3% (Group 11). All sections are shown at the same magnification (scale bar at top right = 640 microns). The surface of the skin is oriented toward the top and left of each panel. Arrows in each section denote the panniculus carnosus, an anatomic layer that separates the first layer of subdermal fat from deeper, subpannieular fat (separation artifact is commonly seen deep to the panniculus and is not an in vivo process).
[0091] Figure 4 shows mean, unfasted, serum lipid concentrations for each group (day 28), expressed as a percent reduction relative to control (Group I).

[0093] Figure 6 depicts a controlled, repeat¨dose, 4¨week, dose¨ranging study of latanoprost transdermal cream was conducted in Zucker Diabetic Fatty (ZDF) rats (ZDF¨
LeprfalCr1), which are defective for the leptin receptor, obese, hyperlipidemic, and diabetic.
Male ZDF rats, approximately 8 weeks old, were obtained from Jackson Laboratories and acclimated to the facility. They were prospectively assigned to treatment conditions shown in Figure 6. There were 3 animals per treatment arm. Test articles were applied in a thin film to the right flank without occlusive dressings, at 0.3 ml daily for 28 days. Rats were fed ad libitum and housed in the same room in 4 cages according to group. They were observed for condition and weighed daily. Food consumption was measured by residual weight of chow.
Animals were fasted overnight prior to day 29, and Oral Glucose Tolerance Tests were conducted on day 29 (1 g glucose per kg body weight). Skin tissue and serum chemistries were collected at day 29.
[0094] Figure 7 depicts shows mean weight gain, by group, for days 0 to 29.
Compared to vehicle, topical latanoprost 0.5%, 0.05%, 0.005% caused a dose¨dependent reductions in weight gain, which were statistically significant for the 0.5% and 0.05%
concentrations.
[0095] Figure 8 shows representative histologic sections of skin and subcutaneous fat from untreated (left) and treated (right) flanks of animals assigned to vehicle only (Group 1), latanoprost 0.005% (Group 2), and latanoprost 0.5% (Group 4). All sections are shown at the same magnification (scale bar at top right = 500 microns). The surface of the skin is oriented toward the top of each panel.
[0096] Figure 9 summarizes serum lipid levels by group, as measured on day 29.
Compared to vehicle¨treated control animals, latanoprost was associated with dose¨dependent reductions in triglycerides and LDL, and dose¨dependent increases in HDL and HDL:LDL ratio.
These benefits were seen at the 0.5% and 0.05% concentrations, and were absent at the 0.005%
concentration. Because of the small sample size. these differences did not reach statistical significance, except for the HDL:LDL ratio of Latanoprost 0.5% vs. vehicle (one- sided p < .05).
[0097] Figure 10 shows the results of oral glucose tolerance testing on day 29.
Latanoprost caused dose¨dependent improvements in oral glucose tolerance, seen at the 0.5%
and 0.05% concentration.
[0098] Figure 11 indicates the serum glucose Area Under the Curve from 15 to 120 minutes post¨glucose load (AUC15_120) was 12% and 26% lower in animals treated with latanoprost 0.05% and 0.5%, respectively, compared to vehicle¨treated animals.
There was no effect on oral glucose tolerance with latanoprost 0.005%.

Detailed Description of Certain Embodiments of the Invention [00100] The present invention describes uses of certain prostaglandins, i.e., one or more compounds of compounds of Formula (I) or (II), or a pharmaceutically acceptable salt, hydrate, solvate, stereoisomer, polymorph, tautomer, isotopically enriched derivative, or prodrug thereof, as described herein, to reduce, or eliminate altogether, body fat, for example, adipose tissue and/or adipocytes, in a subject, for example, a human. The invention further relates to uses of said compounds to reduce the concentration of lipid (e.g., triglycerides, cholesterol, lipoproteins (e.g., low density lipoprotein and very low density lipoprotein)), and/or increase HDL, in the blood of a subject.
[00101] Previously members of the genus of F¨series prostaglandins were recognized as hypotensive agents. For example, see U.S. Pat. Nos. 5,688,819 and 6.403,649.
These compounds were shown to effect vasodilation and thereby were predicted to relieve symptoms of various diseases associated with increased blood pressure, including acute myocardial infarction, vascular thrombosis, hypertension, pulmonary hypertension, ischemic heart disease, congestive heat failure, and angina pectoris. These compounds were also shown to be effective ocular hypotensive agents useful for the treatment of elevated intraocular pressure, for example, glaucoma.
[00102] Previous studies have shown that the use of bimatoprost eyedrops for the treatment of glaucoma does decrease intraocular pressure, but also induces unwanted side effects, which were eventually understood to be due to the atrophy of the fat normally present around the eye, i.e., the orbital fat. The use of bimatoprost to reduce unwanted fat by local administration was disclosed in U.S. Pat. No. 7,666,912.
[00103] The present invention arises in part from a new finding that administration of certain F¨series prostaglandins to obese, dyslipidemic, and/or diabetic animals has beneficial effects on disorders associated with metabolic syndromes in these animals. The observed effects include reduced obesity, reduced weight gain, reduce serum triglycerides, reduced serum LDL, increased serum EIDL, reduced serum glucose, and/or improved glucose tolerance.
[00104] The present invention also arises from the observation that systemic administration of certain F¨series prostaglandins to obese animals reduces weight and/or weight gain in those animals.
[00105] The present invention also arises from the experimental identification of certain preferred species from among the genus of F¨series prostaglandins for the purposes of the invention.
[00106] Prior to this work, it was envisioned that bimatoprost, when non-systemically and locally administered topically, subcutaneously, intramuscularly, or intralesionally at certain concentrations, e.g., 0.003%, 0.03%, or 0.3%, would locally reduce fat in a subject at the site of administration. See, e.g., the Examples of U.S. Patent No. 7,666,912. In a human, an overall dose of 30 mg/m2/d (about 57 mg) using 0.3% ointment would involve application of about 20 g of ointment daily. The inventor has now discovered that while 0.3% topical bimatoprost (at an overall dose of about 30 mg/m2/d) locally reduces subcutaneous fat in a subject, the isopropyl ester and free acid of bimatoprost are significantly more effective in reducing subcutaneous fat.
The inventor has further observed that while topical administration of bimatoprost locally reduces fat, topical administration of the isopropyl ester and free acid of bimatoprost reduces fat not only locally but also throughout the body, indicative of a systemic effect. In fact, topical administration of 0.3% bimatoprost isopropyl ester (at an overall dose of about 30 mg/m2/d) shows a significant systemic effect in reduction of serum lipids in the bloodstream of a subject, while topical administration of bimatoprost shows no systemic effect. See Example 1 below.
The findings and observations disclosed herein are indeed surprising and unexpected, especially considering U.S. Patent 7,666.912 dissuades from systemically administering such compounds.
[00107] Furthermore, the inventor discovered that, unlike transdermal administration of bimatoprost ester or the free acid, neither subcutaneous nor intraperitoneal administration of bimatoprost ester or free acid had any significant effect on fat reduction.
Without wishing to be bound by any particular theory, the inventor postulates that even if the compound is eliminated rapidly from the bloodstream (e.g., latanoprost has a serum elimination half¨life of about 17 minutes), transdermal administration may provide a depot effect whereby a compound applied to the skin may result in slow release of the active ingredient into the bloodstream, and thereby result in a more sustained therapeutically effective concentration in the bloodstream.

Furthermore, without wishing to be bound by theory, a similar effect can be obtained, for example, with a time release formulation, such as a controlled, extended, or sustained release formulation for oral, subcutaneous, intraperitoneal administration, or a continuous intravenous infusion, and the like.
[00108] Without wishing to be bound by any particular theory, reduction in fat as a function of administration of the compounds disclosed herein may include reducing the number of fat cells (adipocytes), reducing the volume of one or more fat cells (adipocytes), reducing maturation of one or more fat cells (adipocytes), and/or dedifferentiating one or more fat cells (adipocytes). Such effects may be mediated through prostaglandin or prostaglandin¨like receptors, and compounds according to the invention may exert their effects as herein disclosed by acting as agonists at these receptors. Because adipocytes have been specifically implicated in a wide array of human diseases, the present invention suggests a means for treating and/or preventing ad ipocyte¨related diseases, such as, but not limited to, metabolic syndrome, diabetes (e.g., type 2 diabetes), liver disease, atherosclerosis, fatty liver, hepatic fibrosis, inflammation or inflammatory disease, depression, and dementia. The invention can be used to reduce adipocytes by administration of one or more of the compounds described herein, e.g., one or more compounds of the Formula (I) or (II).
[00109] Thus, in one aspect, the present invention is directed to the use of certain prostaglandins, e.g., one or more compounds of the Formula (I) or (II), for treating and/or preventing metabolic syndrome or a disorder associated with metabolic syndrome in the body of a subject, by systemically administering the compound to the subject, e.g., at a concentration sufficient to produce a systemic effect in the bloodstream of a subject. More specifically a condition such as obesity, dyslipidemia, and/or a diabetic condition may be treated and/or prevented by administering to a subject a compound described herein.
Furthermore, diseases and/or medical outcomes associated with the metabolic syndrome, obesity, dyslipidemia, and/or a diabetic condition may be treated and/or prevented by administering to a subject a compound described herein.
[00110] The F¨series prostaglandins disclosed herein are considered to be members of the class of prostaglandin F2cc receptor agonists, which are known to be in vitro inhibitors of adipocyte differentiation and survival. See, e.g., Serrero et al. (1992) Biochern. Biophys. Res.
Commun. 183:438-442; Lepak et al. (1993) Prostaglandins 46:511-517; Serrero et al. (1995) Biochem. Biophys. Res. Commun.212:1125-1132; and Lepak et al. (1995) Endocrinology 136:3222-3229. Accordingly, without wishing to be bound by any particular theory, the fat¨
reducing properties of these compounds may relate to its agonism of prostaglandin or prostaglandin¨like receptors, in particular the prostaglandin FP receptor (PTGFR).

[00272] A pharmaceutical formulation may comprise excipients that cause the active pharmaceutical ingredient(s) to be transported, trafficked, deposited, concentrated, and/or retained in adipose tissue or more specifically, in or near an adipocyte. For example, a "lipophilic excipient" (e.g., selected from the group consisting of an liposomes, oil, a surface active agent, an emulsifier, or a mixture thereof, as defined above and herein) may be used in an enteral (e.g., oral) formulation, whereby the active ingredient is administered with a lipophilic excipient, which together are absorbed by enterocytes of the small intestine and formed into chylomicrons, which are in turn preferentially transported by the bloodstream to adipose tissue.
As an alternative example, liposomes may be used as a lipophilic excipient for enteral, parenteral, or topical formulation.
[00273] Liquid dosage forms for oral and parenteral administration include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active ingredient, the liquid dosage forms may comprise inert diluents commonly used in the art such as, for example, water or other solvents (e.g, ethyl carbonate, ethyl acetate, benzyl benzoate, dimethylfonnamide), fatty acid esters of sorbitan, polysorbates, solubilizing agents such as alcohols (e.g., ethyl alcohol. isopropyl alcohol, tetrahydrofurfuryl alcohol, benzyl alcohol, glycerol and glycols (e.g., l.3¨butylene glycol, propylene glycol, polyethylene glycols)), oils (e.g., cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), Cremophor, cyclodextrins, polymers) and mixtures thereof. Besides inert diluents, the oral compositions can include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents. In certain embodiments, for parenteral administration, the active ingredient is mixed with solubilizing agents such as Cremophor, =
alcohols, oils, modified oils, glycols, polysorbates, cyclodextrins, polymers, and combinations thereof.
[00274] Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions can be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation can be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3¨butanediol. Among the acceptable vehicles and solvents that can be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono¨ or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.
[00275] The injectable formulations can be sterilized, for example, by filtration through a bacterial¨retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.
[00276] Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active ingredient is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, f) absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof In the case of capsules, tablets and pills, the dosage form may comprise buffering agents.
[00277] Solid compositions of a similar type can be employed as fillers in soft and hard¨
filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally comprise opacifying agents and can be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions which can be used include polymeric substances and waxes. Solid compositions of a similar type can be employed as fillers in soft and hard¨filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polethylene glycols and the like.
[00278] The active ingredient can be provided in micro¨encapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings and other coatings well known in the pharmaceutical formulating art.
In such solid dosage forms the active ingredient can be admixed with at least one inert diluent such as sucrose, lactose or starch. Such dosage forms may comprise, as is normal practice, additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms may comprise buffering agents. They may optionally comprise opacifying agents and can be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions which can be used include polymeric substances and waxes.
[00279] Compositions for rectal or vaginal administration are typically suppositories which can be prepared by mixing the active ingredient with a suitable non¨irritating excipient or carrier such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active ingredient.
[00280] In certain embodiments, the pharmaceutical composition further comprises one or more excipients adapted for transdermal administration. Dosage forms for topical and/or transdermal administration of an active ingredient may include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants and/or patches.
Generally, the active ingredient is admixed under sterile conditions with a pharmaceutically acceptable carrier and/or any needed preservatives and/or buffers as can be required. Additionally, the present invention contemplates the use of transdermal patches, which often have the added advantage of providing controlled delivery of an active ingredient to the body. Such dosage forms can be prepared, for example, by dissolving and/or dispensing the active ingredient in the proper medium.
Alternatively or additionally, the rate can be controlled by either providing a rate controlling membrane and/or by dispersing the active ingredient in a polymer matrix and/or gel. Exemplary carriers for transdermal administration include dimethyl sulfoxide, HRT
(hormone replacement therapy) base, PluronicTM lecithin organogel, Lipoderm , Vanpen0, Aladerm , and anhydrous gels.

[00282] Formulations suitable for topical administration include, but are not limited to, liquid and/or semi liquid preparations such as liniments, lotions, oil in water and/or water in oil emulsions such as creams, ointments and/or pastes, and/or solutions and/or suspensions.
Topically¨administrable formulations may, for example, comprise from about 0.3% to about 10% (w/w) or (w/v) of the active ingredient, although the concentration of the active ingredient can be as high as the solubility limit of the active ingredient in the solvent. Formulations for topical administration may further comprise one or more of the additional ingredients described herein.

[00283] A pharmaceutical composition can be prepared, packaged, and/or sold in a formulation suitable for pulmonary administration via the buccal cavity. Such a formulation may comprise dry particles which comprise the active ingredient and which have a diameter in the range from about 0.5 to about 7 nanometers or from about 1 to about 6 nanometers. Such compositions are conveniently in the form of dry powders for administration using a device comprising a dry powder reservoir to which a stream of propellant can be directed to disperse the powder and/or using a self propelling solvent/powder dispensing container such as a device comprising the active ingredient dissolved and/or suspended in a low¨boiling propellant in a sealed container. Such powders comprise particles wherein at least 98% of the particles by weight have a diameter greater than 0.5 nanometers and at least 95% of the particles by number have a diameter less than 7 nanometers. Alternatively, at least 95% of the particles by weight have a diameter greater than 1 nanomctcr and at least 90% of the particles by number have a diameter less than 6 nanometers. Dry powder compositions may include a solid fine powder diluent such as sugar and are conveniently provided in a unit dose form.
[00284] Low boiling propellants generally include liquid propellants having a boiling point of below 65 F at atmospheric pressure. Generally the propellant may constitute 50 to 99.9% (w/w) of the composition, and the active ingredient may constitute 0.1 to 20% (w/w) of the composition. The propellant may further comprise additional ingredients such as a liquid non¨ionic and/or solid anionic surfactant and/or a solid diluent (which may have a particle size of the same order as particles comprising the active ingredient).
[00285] Pharmaceutical compositions formulated for pulmonary delivery may provide the active ingredient in the form of droplets of a solution and/or suspension.
Such formulations can be prepared, packaged, and/or sold as aqueous and/or dilute alcoholic solutions and/or suspensions, optionally sterile, comprising the active ingredient, and may conveniently be administered using any nebulization and/or atomization device. Such formulations may further comprise one or more additional ingredients including, but not limited to, a flavoring agent such as saccharin sodium, a volatile oil, a buffering agent, a surface active agent, and/or a preservative such as methylhydroxybenzoate. The droplets provided by this route of administration may have an average diameter in the range from about 0.1 to about 200 nanometers.
[00286] The formulations described herein as being useful for pulmonary delivery are useful for intranasal delivery of a pharmaceutical composition of the invention. Another formulation suitable for intranasal administration is a coarse powder comprising the active ingredient and having an average particle from about 0.2 to 500 micrometers.
Such a formulation is administered, by rapid inhalation through the nasal passage from a container of the powder held close to the s suitable for nasal administration may, for example, comprise from about as little as 0.1% (w/w) and as much as 100% (w/w) of the active ingredient, and may comprise one or more of the additional ingredients described herein. A
pharmaceutical composition of the invention can be prepared, packaged, and/or sold in a formulation suitable for buccal administration. Such formulations may, for example, be in the form of tablets and/or lozenges made using conventional methods, and may contain, for example, 0.1 to

20% (w/w) active ingredient, the balance comprising an orally dissolvable and/or degradable composition and, optionally, one or more of the additional ingredients described herein.
Alternately, formulations suitable for buccal administration may comprise a powder and/or an aerosolized and/or atomized solution and/or suspension comprising the active ingredient.
Such powdered, aerosolized, and/or aerosolized formulations, when dispersed, may have an average particle and/or droplet size in the range from about 0.1 to about 200 nanometers, and may further comprise one or more of the additional ingredients described herein.
[00287] A pharmaceutical composition of the invention can be prepared, packaged, and/or sold in a formulation suitable for ophthalmic administration. Such formulations may, for example, be in the form of eye drops including, for example, a 0.1/1.0% (w/w) solution and/or suspension of the active ingredient in an aqueous or oily liquid carrier. Such drops may further comprise buffering agents, salts, and/or one or more other of the additional ingredients described herein. Other ophthalmically¨administrable formulations which are useful include those which comprise the active ingredient in microcrystalline form and/or in a liposomal preparation. Ear drops and/or eye drops are contemplated as being within the scope of this invention.
[00288] Although the descriptions of pharmaceutical compositions provided herein are principally directed to pharmaceutical compositions that are suitable for administration to humans, it will be understood by the skilled artisan that such compositions are generally suitable for administration to animals of all sorts. Modification of pharmaceutical compositions suitable for administration to humans in order to render the compositions suitable for administration to various animals is well understood, and the ordinarily skilled veterinary pharmacologist can design and/or perform such modification with ordinary experimentation. General considerations in the formulation and/or manufacture of pharmaceutical compositions can be found, for example, in Remington: The Science and Practice of Pharmacy 21st ed., Lippincott Williams &
Wilkins, 2005.
[00289] Still further encompassed by the invention are kits comprising a compound as described herein and instructions for use. Kits provided may comprise a provided composition and a container (e.g., a vial, ampoule, bottle, syringe, and/or dispenser package, or other suitable container). In some embodiments, provided kits may optionally further include a second container comprising a suitable aqueous carrier for dilution or suspension of the provided composition for preparation of administration to a subject. In some embodiments, contents of provided formulation container and solvent container combine to form at least one unit dosage form.
[00290] The active ingredient can be administered using any amount and any route of administration effective for treatment. The exact amount required will vary from subject to subject, depending on the species, age, and general condition of the subject, the severity of the infection, the particular composition, its mode of administration, its mode of activity, and the like.
[00291] T,he active ingredient is typically formulated in dosage unit form for ease of administration and uniformity of dosage. It will be understood, however, that the total daily , usage of the compositions of the present invention will be decided by the attending physician within the scope of sound medical judgment. The specific therapeutically effective dose level for any particular subject will depend upon a variety of factors including the condition being treated and the severity of the condition; the activity of the specific active ingredient employed;
the specific composition employed; the age, body weight, general health, sex and diet of the subject; the time of administration, route of administration, and rate of excretion of the specific active ingredient employed; the duration of the treatment; drugs used in combination or coincidental with the specific active ingredient employed; and like factors well known in the medical arts.
[00292] The active ingredient can be administered by any route, including enteral (e.g., oral, rectal), parenteral (e.g., intravenous, intramuscular, intra¨artcrial, intramedullary, intrathecal, subcutaneous, intraventricular, interdermal), and topical administration (e.g., transdermal, transmucosal).

[00293] In certain embodiments, the active ingredient is administered systemically. As used herein, "syStemic administration" or "administering systemically" or "systemic effect"
means administration to the subject by enteral, parenteral, or topical (e.g., transdermal) administration, whereby the active ingredient or active metabolite thereof reaches and maintains a therapeutically effective concentration in the bloodstream for a period of time. A systemic effect is distinguishable from a local effect in a variety of ways, e.g., for example, as demonstrated in Example 1, a systemic effect is indicative of fat reduction in both treated and untreated areas of a subject's body.
[00294] In certain embodiments, "systemic administration" or "administering systemically" or "systemic effect" refers to the administration of an active ingredient to the subject, whereby the active ingredient or active metabolite thereof reaches and maintains a therapeutically effective concentration in the bloodstream for at least 4 hours, at least 8 hours, at least 10 hours, at least 12 hours, at least 15 hours, at least 24 hours, between 4 hours and 24 hours, between 8 hours and 24 hours, between 10 hours and 24 hours, or between 15 hours and 24 hours. In certain embodiments, the administration is transdermal administration. Without wishing to be bound by any particular theory, even if the active ingredient is eliminated rapidly from the bloodstream (e.g., latanoprost has a serum elimination half¨life of about 17 minutes), transdermal administration can provide a depot effect whereby a single application to the skin can result in slow release of the active ingredient into the bloodstream, and thereby result in a more sustained therapeutically effective concentration in the bloodstream.
Other formulations or techniques, such as time release formulations or continuous IV infusion, may enable this desired slow release of the active ingredient via other routes of administration.
[00295] In certain embodiments, the active ingredient is administered to the subject twice daily, daily, every 3 days, or weekly for at least 1 week, at least 2 weeks, at least one month, at least 2 months, at least 3 months, at least 4 months, at least 5 months, at least 6 months, between I week to 6 months, between 2 weeks to 6 months, between 1 month to 6 months, between 2 months to 6 months, between 3 months to 6 months, between 4 months to 6 months or between 5 months to 6 months. In certain embodiments, the administration is transdermal administration.
In certain embodiments, the active ingredient is administered transdermally once daily.
[00296] The exact amount of the active ingredient required to achieve a therapeutically effective amount will vary from subject to subject, depending, for example, on species, age, and =
general condition of a subject, severity of the side effects or disorder, identity of the particular compound(s), mode of administration, and the like. The desired dosage can be delivered three times a day, two times a day, once a day, every other day, every third day, every week, every two weeks, every three weeks, or every four weeks. In certain embodiments, the desired dosage can be delivered using multiple administrations (e.g., two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, or more administrations). As demonstrated in the accompanying Examples, daily administration to the subject can be adequate (but not necessarily preferable) to achieve the desired effect. A daily administration schedule is considered convenient for human use. The active ingredient may be administered by the subject to himself or herself repeatedly and without special equipment or training, although a medical professional also can also administer the active ingredient to the subject.
[00297] It will be appreciated that dose ranges as described herein provide guidance for the administration of provided pharmaceutical compositions to an adult. The amount to be administered to, for example, a child or an adolescent can be determined by a medical practitioner or person skilled in the art and can be lower or the same as that administered to an adult.
[00298] In certain embodiments, a therapeutically effective concentration of the compound is in the range of about 50 pg/ml and 1000 pg/ml, inclusive, e.g., greater than 50 pg/ml, greater than 60 pg/ml, greater than 70 pg/ml, greater than 80 pg/ml, greater than 90 pg/ml, greater than 100 pg/ml, greater than 150 pg/ml, greater than 200 pg/ml, greater than 250 pg/ml, greater than 300 pg/ml, greater than 350 pg/ml, greater than 400 pg/ml, greater than 450 pg/ml, greater than 500 pg/ml, greater than 550 pg/ml, greater than 600 pg/ml, greater than 650 pg/ml, greater than 700 pg/ml, greater than 750 pg/ml, greater than 800 pg/ml, greater than 850 pg/ml, greater than 900 pg/ml, greater than 950 pg/ml. The present invention contemplates a significant amount of compound or active metabolite thereof, e.g., the free acid, to appear systemically, i.e., in the blood. However, the concentration is not necessarily maintained within this range throughout the entire dosing interval, and may fluctuate during the dosing interval.
[00299] In certain embodiments, the compound is administered, e.g., orally, subcutaneously, or intravenously, at a dose of between about 0.5 mg in a 24¨hour period and about 50 mg in a 24¨hour period, inclusive. e.g., between about 0.5 mg to about 40 mg, between about 0.5 mg to about 30 mg, between about 0.5 mg to about 20 mg, between about 0.5 mg to about 10 mg, between about 0.5 mg to about 5 mg, between about 1 mg to about 50 mg, between about 10 mg to about 50 mg, between about 15 mg to about 50 mg, between about 20 mg to about 50 mg, between about 30 mg to about 50 mg, between about 40 mg to about 50 mg, in a 24¨hour period, inclusive.

In certain embodiments, the composition comprises greater than 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1.0%, 2.0%, 3.0%, 4.0%, 5.0%, 6.0%, 7.0%, 8.0%, 9.0%, or 10.0% (w/v) of the active ingredient. In certain embodiments, the composition comprises between about 0.4% and about 10%, weight per volume, inclusive. In certain embodiments, the composition comprises between about 0.4% and about 2%, weight per volume, inclusive.
[00304] In a particular embodiment, a composition for application to the skin comprises at or greater than or equal to about 0.3% (w/v) of the active ingredient in order to achieve a systemic effect. In certain embodiments, the composition comprises greater than 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1.0%, 2.0%, 3.0%, 4.0%, 5.0%, 6.0%, 7.0%, 8.0%, 9.0%, or 10.0% (w/v) of the active ingredient. In certain embodiments, the composition comprises between about 0.4% and about 10%, weight per volume, inclusive. In certain embodiments, the composition comprises between about 0.4% and about 2%, weight per volume, inclusive.

[00305] In a particular embodiment, a composition for subcutaneous injection comprises at or greater than or equal to 0.05% (w/v) of the active ingredient in order to achieve a systemic effect. In certain embodiments, the composition comprises greater than 0.1%, 0.3%, 0.5%, 1%, 2%, 3%, 4%, 5.0%, 6.0%, 7.0%, 8.0%, 9.0%, or 10.0% (w/v) of the active ingredient. In certain embodiments, the composition comprises between about 0.4% and about 10%, weight per volume, inclusive. In certain embodiments, the composition comprises between about 0.4% and about 2%, weight per volume, inclusive.
[00306] In certain embodiments, the compound is administered at a dose of about 0.5 mg/m2/d to about 50 mg/m2/d, e.g., between about 0.5 mg/m2/d to about 40 mg/m2/d, between about 0.5 mg/m2/d to about 30 mg/m2/d, between about 0.5 mg/m2/d to about 20 mg/m2/d, between about 0.5 mg/m2/d to about 10 mg/m2/d, between about 0.5 mg/m2/d to about 5 mg/m2/d, between about 0.5 mg/m2/d to about 4 mg/m2/d, between about I mg/m2/d to about 5 mg/m2/d, between about 2 mg/m2/d to about 5 mg/m2/d, between about 3 mg/m2/d to about 5 mg/m2/d, between about 3 mg/m2/d to about 4 mg/m2/d, between about 5 mg/m2/d to about 50 mg/m2/d, between about 10 mg/m2/d to about 50 mg/m2/d, between about 20 mg/m2/d to about 50 mg/m2/d, between about 30 mg/m2/d to about 50 mg/m2/d, or between about 40 mg/m2/d to about 50 mg/m2/d, in a 24¨hour period, inclusive.
[00307] It is appreciated that more potent compounds may be administered at lower dosages than less potent compounds. For example, as shown in Example 3, a latanoprost dose of about 3.7 mg/m2/d may be acceptable for systemic therapy, but for more potent compounds the systemic dose could be lower.
[00308] It will be also appreciated that the active ingredient can be administered in combination with one or more additional therapeutically active agents ("agents" or "active agents"). The compound or composition can be administered concurrently with, prior to, or subsequent to, one or more additional agents. In general, the active ingredient and each additional active agent will be administered at a dose and/or on a time schedule determined for the ingredient and agent. In will further be appreciated that the active ingredient and active agent utilized in this combination can be administered together in a single composition or administered separately in different compositions. The particular combination to employ in a regimen will take into account compatibility of the active ingredient with the active agent and/or the desired therapeutic effect to be achieved. In general, it is expected that additional active agents utilized in combination be utilized at levels that do not exceed the levels at which they are utilized individually. In some embodiments, the levels utilized in combination will be lower than those utilized individually.
[00309] The active ingredient can be administered in combination with active agents that improve their bioavailability, reduce and/or modify their metabolism, inhibit their excretion, and/or modify their distribution within the body.

Body fat can be measured by skin calipers, dual energy x¨ray Absorptiometry (DEXA), computed tomography (CT), magnetic resonance imaging (MRI), or any other suitable method known in the art, The measurement can be of total body fat, or only body fat on a particular part of the body. Fat reduction can also include reducing fat cell amount (for example, fat cell number), reducing fat cell volume, reducing fat cell maturation, and/or dedifferentiating a fat cell. These phenomena can be seen and measured, for example, by histologic examination of body fat.
[00318] The present invention is expected to reduce fat by greater than or equal to 75%, greater than or equal to 70%, greater than or equal to 60%, greater than or equal to 50%, greater than or equal to 40%, greater than or equal to 30%, greater than or equal to 25%, greater than or equal to 20%, greater than or equal to 15%, greater than or equal to 10%, or greater than or equal to 5%.
[00319] In certain embodiments, the subject is overweight. "Overweight" is a medical condition, and is defined by the subject's BMI. Any subject with a BMI of greater than or equal to 25 is considered overweight. An overweight subject encompasses pre¨obese subjects (e.g., having a BMI of between 25 and 30) and obese subjects (e.g., having a BMI of greater than or equal to 30). In some embodiments of the invention, methods or compositions used to treat or prevent "obesity" can likewise be used to treat or prevent "overweight" or "pre¨obesity."
[00320] In certain embodiments, the overweight subject is obese and suffers from obesity.
Any subject with a BMI of between 35 and 40, inclusive, is considered "severely obese" and suffers from "severe obesity". Any subject with a BMI between 40 and 45 is considered "morbidly obese" and suffers from "morbid obesity". Any subject with a BMI
greater than or equal to 45 is considered "super obese" and suffers from "super obesity".
[00321] In certain embodiments, the subject has obesity as a side effect of medication (e.g., for example, cortisol and analogs, corticosteroids, megace, sulfonylureas, anti¨retrovirals, antidepressants, monoamine oxidase inhibitors, selective serotonin reuptake inhibitors, oral contraceptives, insulin or a form of insulin, risperidone, clozapine, and thiazolidinediones).
[00322] In certain embodiments, the subject has obesity due to changes in hormonal status (e.g., as a result of physiologic changes such as pregnancy or menopause).
[00323] In certain embodiments, the subject with obesity is undergoing or has recently undergone smoking cessation.
[00324] In certain embodiments, the subject with obesity is also suffering or likely to suffer from diabetes, hypertension, hyperlipidemia, coronary artery disease, stroke, sleep apnea, gallbladder disease, gastroesophogeal reflux disease, fatty liver disease, gout, thromboembolism, elevated blood pressure, elevated blood sugar, elevated serum cholesterol, elevated serum uric acid, cancer (e.g., breast cancer, colon cancer, lipomas, fatty tumors, particularly if there are multiple fatty tumors), or a genetic disorder or medical condition characterized at least in part by excess body fat (e.g., Cushing syndrome, pseudo¨Cushing syndrome, drug¨induced obesity, I IIV¨related lipodystrophy, partical lipodystrophy, benign symmetric lipomatosis, Madclung's disease, hypothyroidism, pseudohypoparathyroid ism, hypothalamic obesity, polycystic ovarian disease, depression, binge eating, Prader¨Willi syndrome, Bardet¨Biedl syndrome, Cohen syndrome, Down syndrome, Turner syndrome, growth hormone deficiency, growth hormone resistance, and leptin deficiency or resistance). The present invention contemplates treating any such disease, disorder, or condition using any of the described inventive methods.
[00325] In certain embodiments, the subject is not overweight. For example, the method of reducing body fat in a subject is contemplated useful for not only treating obesity in a subject, but also useful in treating subjects who are not overweight, but still desire to increase the proportion of lean body mass to toal body mass.
[00326] In certain embodiments, the subject does not suffer from metabolic syndrome.
[00327] In certain embodiments, the methods of the present invention are useful for treating or preventing an adipocyte¨related disease. As used herein, "adipocyte¨related disease"
means a disease: (i) wherein reduction of adipocytes treats the disease, disorder, or condition from which the subject is suffering; or (ii) whose mechanism comprises an adipocyte and/or its molecular products, e.g., secreted proteins, e.g., adiponectin, resistin, tumor necrosis factor alpha (TNF¨cc), interleukin-6 (IL-6), C¨reactive protein (CRP), fibrinogen, plasminogen activator inhibitor-1 (PA1-1), and/or C¨terminal binding protein (CtBP). Exemplary ad ipocyte¨related diseases include, but are not limited to, metabolic syndrome, excess body fat (e.g., being overweight, obesity), dyslipidemia, hypercholesterolemia, hypertriglyceridemia, diabetes (e.g., type 2 diabetes), atherosclerosis, vascular disease, coronary artery disease, stroke, cerebrovascular disease, peripheral vascular disease, fatty liver, pancreatitis, inflammation or inflammatory disease, depression, and dementia. In certain embodiments, the adipocyte¨related disease is selected from the group consisting of metabolic syndrome, diabetes (e.g., type 2 diabetes), liver disease, atherosclerosis, fatty liver disease, inflammation or inflammatory disease, depression, and dementia. In certain embodiments, treatment of an adipocyte¨related disease can be accomplished by reduction of adipocytes that is microscopic rather than macroscopic, or diffuse rather than focal.

Other Uses of the Compositions and Compounds [00189] Given the ability of the compounds disclosed herein to reduce fat, adipocytes, and lipid concentrations, and the association of these species with metabolic pathways and disease (e.g., as part of the metabolic syndrome), it is further envisioned that the compounds, compositions, and methods described herein may be used to lower one or more of the following clinical parameters in a body: serum glucose concentration, glycated hemoglobin concentration (i.e., hemoglobin AlC, "HbAlc"), circulating insulin concentration, serum urate concentration, concentration(s) of hepatic serum biomarkers, e.g. transaminases, and concentrations of pancreas¨related serum biomarkers, e.g. amylase and lipase. As used herein, the term "serum glucose concentration" is intended to encompass any suitable measure of the concentration of glucose in the blood.
[00190] It is further envisioned that compounds, compositions, and methods described herein may be used to improve an individual's response to insulin (i.e., treat insulin resistance) or to leptin (i.e., treat leptin deficiency).

Examples [00340] Throughout the description, where laboratory assays, e.g. for glucose or lipid concentrations, refer to a particular matrix, e.g. serum, it is to be understood that such assays may, depending on the analyte, be conducted on other matrices or sample types, e.g. plasma, or with other technologies, e.g., noninvasive methods, that yield comparable measurements.
[00341] Throughout the description, where compositions are described as having, including, or comprising specific components, or where processes are described as having.
including, or comprising specific process steps, it is contemplated that compositions of the present invention may also consist essentially of, or consist of, the recited components, and that the processes of the present invention may also consist essentially of, or consist of, the recited processing steps. Further, it should be understood that the order of steps or order for performing certain actions are immaterial so long as the invention remains operable.
Moreover, two or more steps or actions may be conducted simultaneously.
[00342] In light of the foregoing description, the specific non¨limiting examples presented below are for illustrative purposes and not intended to limit the scope of the invention in any way.
Example 1 [00343] A randomized, controlled, repeat¨dose, 4¨week trial was conducted on (db¨ldb¨) mice, which are defective for the leptin receptor (Jackson Laboratories).
These mice are genetically obese, dyslipidemic, and diabetic.
[00344] Methods: Mice were obtained from Jackson Laboratories and acclimated to the facility. At about 5 weeks of age, mice were prospectively randomized into groups and assigned to the treatment conditions shown in Figure 1. Topical treatments were applied in a thin film to the right flank skin without occlusive dressings; subcutaneous injections were also administered to the right flank. Mice were observed for condition and weighed daily. They were housed in the same room, in 11 cages according to group, and fed ad libitum. Skin tissue was sampled and serum lipids tested on day 28. Tissue was fixed in formalin and stained with hematoxylin and eosin.
[00345] Results: Animals fed and behaved normally throughout the study.
Skin condition remained normal. Mean weight gain for days 0 to 28, by group, is shown in Figure 2. Animals treated with vehicle only (Groups 1 and 2) showed an expected amount of weight gain for the strain (normative data, Jackson Laboratories). Transdermal bimatoprost isopropyl ester (BIE) and bimatoprost free acid (BFA) reduced weight gain significantly and in a dose¨dependent manner, but topical bimatoprost did not. Subcutaneous BIE, subcutaneous BFA, and intraperitoneal BFA had no significant effect on weight gain.
[00346] Figure 3 shows representative histologic sections of skin and subcutaneous fat from untreated (left) and treated (right) flanks of animals assigned to vehicle only (Group 1), topical bimatoprost 0.3% (Group 4), and topical BIE 0.3% (Group 11). All sections are shown at the same magnification (scale bar at top right = 640 microns). The surface of the skin is oriented toward the top and left of each panel. Arrows in each section denote the panniculus carnosus, an anatomic layer that separates the first layer of subdermal fat from deeper, subpannicular fat (separation artifact is commonly seen deep to the panniculus and is not an in vivo process).
[00347] In vehicle¨only treated animals (Group 1), the adipose layer between skin and panniculus was thick, with approximately 10 pseudo¨layers of plump adipocytes.
[00348] In animals treated with topical bimatoprost 0.3%, smaller adipocytes and a thinner adipose layer were seen on the right (treated) flank but not on the left (untreated) flank. The untreated flank resembled that of a vehicle¨treated animal, with a thick adipose layer and plump adipocytes. This observation is consistent with a local effect, but not a systemic effect, from topical bimatoprost at a concentration up to 0.3%.
[00349] In animals treated with topical BIE 0.3%, smaller adipocytes and thinner adipocyte layers were seen on both treated and untreated flanks. The effects were symmetric, indicative of a systemic effect. In contrast to animals treated with vehicle or bimatoprost 0.3%, animals treated with BIE 0.3% also showed profound shrinkage of adipocytes deep to the panniculus (toward bottom of each panel), closer to vasculature, and again indicative of a systemic effect.
[00350] Figure 4 shows mean, unfasted, serum lipid concentrations for each group (day 28), expressed as a percent reduction, relative to control (Group 1). Figure 5 charts the triglyceride and total cholesterol results (mg/di) for the topical treatment conditions as follows:
Group 1 ¨ C, 3¨ D, 4¨ E, 5 ¨ F, 6¨ G, 10 ¨ H, 11 = I.
[00351] Triglycerides were significantly reduced in animals treated with transdermal BFA
(0.1% or 0.3%), and even more so in those treated with transdermal BIE (0.1%
or 0.3%). Total cholesterol was significantly lower in animals treated with transdermal BIE
0.1%. Topical bimatoprost had no significant effect on serum lipids. Subcutaneous BIE, subcutaneous BFA, and intraperitoneal BFA had no significant effect on serum lipids.
[00352] Thus, in a mouse model of obesity and dyslipidemia, the foregoing results show reduced weight gain and serum lipids following transdermal administration of BIE and BFA, but not bimatoprost. Histology pointed to a systemic effect of BIE at concentrations tested, which was not seen with bimatoprost at the same concentrations. Thus, although adipose tissue was reduced by locally active treatment (e.g. by topical bimatoprost 0.3%), significant reductions in serum lipids and overall body weight appeared to occur only with systemically active treatment (e.g. topical BIE 0.3%).
[00353] For each of the above effects, transdermal BIE was more potent that transdermal BFA. Neither subcutaneous nor intraperitoneal administration of any compound had any significant effect due to the compound being quickly metabolized and extruded from the system.
Transdermal administration appears to allow for a more slow exposure of the compound over a more lengthy period of time, e.g., over the dosing interval. Time-release formulations for subcutaneous and intraperitoneal administration of these compounds are contemplated as conferring a systemic effect similar to transdermal administration.
Example 2 [00354] A controlled, repeat-dose, 4-week, dose-ranging study of latanoprost transdermal cream was conducted in Zucker Diabetic Fatty (ZDF) rats (ZDF-Lepia/CrI), which are defective for the leptin receptor, obese, hyperlipidemic, and diabetic.
[00355] Methods: Male ZDF rats. approximately 8 weeks old, were obtained from Jackson Laboratories and acclimated to the facility. They were prospectively assigned to treatment conditions shown in Figure 6. There were 3 animals per treatment arm. Test articles were applied in a thin film to the right flank without occlusive dressings, at 0.3 ml daily for 28 days. Rats were fed ad libitum and housed in the same room in 4 cages according to group.
They were observed for condition and weighed daily. Food consumption was measured by residual weight of chow. Animals were fasted overnight prior to day 29, and Oral Glucose Tolerance Tests were conducted on day 29 (I g glucose per kg body weight).
Skin tissue and serum chemistries were collected at day 29.

[00356] Results: Daily observations and skin condition were unremarkable.
There were no differences in food consumption between treatment conditions. Figure 7 shows mean weight gain, by group, for days 0 to 29. Compared to vehicle, topical latanoprost 0.5%, 0.05%, 0.005%
caused a dose¨dependent reductions in weight gain, which were statistically significant for the 0.5% and 0.05% concentrations.
[00357] Figure 8 shows representative histologic sections of skin and subcutaneous fat from untreated (left) and treated (right) flanks of animals assigned to vehicle only (Group I), latanoprost 0.005% (Group 2), and latanoprost 0.5% (Group 4). All sections are shown at the same magnification (scale bar at top right = 500 microns). The surface of the skin is oriented toward the top of each panel.
[00358] In vehicle¨only treated animals (Group 1), subcutaneous adipose tissue consisted of several pseudolayers of plump adipocytes, which extended into the reticular dermis and were occasionally seen interspersed with panniculus muscle. The dermis was thick.
[00359] In animals treated with latanoprost 0.005%, the right (treated) flank fewer and smaller adipocytes, and a thinner adipose layer. Adipocytes were not interspersed with dermis, and the dermis was thinner than in vehicle¨only animals. The untreated (left) flank resembled that of a vehicle¨treated animal, with a thick adipose layer and full adipocytes. This observation is consistent with a local effect, but not a systemic effect, from topical latanoprost at a concentration of 0.005%.
[00360] In animals treated with topical latanoprost 0.5%, fewer and smaller adipocytes, and thinner adipose layer and dermis were seen on both treated and untreated flanks. The effects were symmetric, indicative of a systemic effect.
[00361] Figure 9 summarizes serum lipid levels by group, as measured on day 29.
Compared to vehicle¨treated control animals, latanoprost was associated with dose¨dependent reductions in triglycerides and LDL, and dose¨dependent increases in HDL and HDL:LDL ratio.
These benefits were seen at the 0.5% and 0.05% concentrations, and were absent at the 0.005%
concentration. Because of the small sample size, these differences did not reach statistical significance, except for the IIDL:LDL ratio of Latanoprost 0.5% vs. vehicle (one¨sided p < .05).
[00362] Figure 10 shows the results of oral glucose tolerance testing on day 29.
Latanoprost caused dose¨dependent improvements in oral glucose tolerance, seen at the 0.5%
and 0.05% concentrations (results for the 0.005% concentration [not shown]
were similar to control). As summarized in Figure 11, the serum glucose Area Under the Curve from 15 to 120 minutes post¨glucose load (AUC15_120) was 12% and 26% lower in animals treated with latanoprost 0.05% and 0.5%, respectively, compared to vehicle¨treated animals.
There was no effect on oral glucose tolerance with latanoprost 0.005%.
[00363] Thus, in a rat model of obesity, dyslipidemia, and diabetes, the foregoing results show reduced weight gain, improved serum lipids, and improved glucose tolerance following transdermal administration of latanoprost at concentrations of 0.5% and 0.05%, but not 0.005%.
These effects were dose¨dependent, and the minimum effective dose for these effects was deemed to be the 0.05% concentration.
[00364] Histology pointed to a systemic effect of latanoprost 0.5%, which was not seen with latanoprost 0.005%. Thus, although adipose tissue was reduced by locally active treatment (e.g. by topical latanoprost 0.005%), significant reductions in serum lipids and overall body weight appeared to occur only in response systemically active treatment (e.g.
topical latanoprost 0.05% or 0.5%).
Example 3 [00365] Figure 12 compares various topical doses of latanoprost in mouse, rat, and human, with respect to projected systemic dose. All calculations assume once¨daily dosing and 100%
serum bioavailability. The derivation of each dose is set forth based on the animal body weight, drug concentration, and drug volume. Finally, doses are scaled allometrically for body surface area (mg/m2/d), as is appropriate for most low¨molecular¨weight molecules.
[00366] In the rat, the minimum effective dose of topical latanoprost for lipid, diabetes, and obesity reduction, which was 0.05%, equivalent to 0.5 mg/ml (Example 2), corresponds to a systemic dose of 3.6 mg/m2/d. This is corroborated in the mouse (Example 1), where serum lipids and obesity responded to BIE, a close analog of latanoprost, at systemic doses of 10 mg/m2/d; a minimum effective dose of13IE was not determined in the mouse.
[00367] In humans, administration of a latanoprost eye drop (Xalatant), which is sufficient to reduce adipose tissue locally around the human eye, nonetheless involves a very low systemic dose of 0.008 mg/m2/d, or 0.016 mg/m2/d if both eyes are treated.
Thus, the recommended human ophthalmic dose, if both eyes are treated, is 450¨fold lower than the minimum effective dose for lipid and obesity reduction in the rat.

[00368] Without any wish to be bound by theory, by comparison to the minimum effective dose of latanoprost in the rat, it is therefore predicted that a human transdermal dose of about 7 mg latanoprost per day would be sufficient to achieve a systemic benefit for serum lipids, a diabetic condition, and/or obesity. This could be delivered, for example, as a daily dose of 1 ml transdermal gel with a concentration 0.7% (w/v) or 7 mg/ml latanoprost.
Example 4 [00369] The following description exemplifies preparation of a pharmaceutical composition of latanoprost gel for transdermal administration to a human.
[003701 700 mg of pure latanoprost powder, made under Good Manufacturing Practice, is fully dissolved in 20 ml of an organic phase consisting of lecithin (about 10 ml), and isopropyl palmitate (about 10 m1). Into the organic phase is slowly mixed 80 ml of an aqueous phase, previously cooled to 4 degrees centrigrade, consisting of poloxamer 407 (about 16-24 ml) and water (q.s.). Suitable preservatives (e.g., sorbic acid, potassium sorbate) are included in the formulation. The mixture is mixed well at room temperature until a gel forms, and the mixture is then processed through an ointment mill. About 100 ml of latanoprost transdennal gel is obtained, at a 7 mg/ml or 0.7% concentration.
Example 5 [00371] The following description exemplifies preparation of a pharmaceutical composition of latanoprost cream for transdermal administration to a human.
[00372] 590 mg of pure latanoprost powder, made under Good Manufacturing Practice, is mixed in a mortar with 5 ml of ethoxy diglycol to form a paste. 100 ml of Lipoderm base (PCCA, Houston, TX) is added geometrically to the mortar. A suitable preservative such as potassium sorbate is added. The mixture is transferred to an electric mortar and pestle and mixed at 2 rpm for 2 minutes. Optionally, the mixture is then run through an ointment mill on setting #2, then setting #1. About 100 ml of latanoprost transdermal cream is obtained, at a 5 mg/ml or 0.5% concentration.

Example 6 [00373] The following description exemplifies preparation of a pharmaceutical composition of latanoprost anhydrous liquid for transdermal administration to a human.
[00374] 630 mg of pure latanoprost powder, made under Good Manufacturing Practice, is mixed with 8.4 ml of bcnzyl alcohol, 33.6 ml of acetone, and isopropyl alcohol q.s. to 84 ml.
The liquid is thoroughly mixed. About 84 ml of latanoprost transdermal liquid is obtained, at a 7.5 mg/ml or 0.75% concentration.
Example 7 [00375] The following description exemplifies a clinical application of the invention to treat obesity, dyslipidemia, and type 2 diabetes mellitus in a man with metabolic syndrome.
[00376] A 52¨year¨old man is suffers from obesity, dyslipidemia, and type 2 diabetes.
Medical evaluation reveals that his height is 5 feet 8 inches and a weight of 240 pounds, corresponding to a body mass index (131V11) of 36.5 (clinically obese). His waist circumference is 42 inches. His noninvasive blood pressure is 184/98. His fasting serum glucose is 137 g/dL and his vlycated hemoglobin (hemoglobin A IC) is 8.1. Fasting serum lipids are as follows:
triglycerides, 220 mg/dL; total cholesterol, 310 mg/dL, LDL 240 mg/dL, HDL, 35 mg/dL. His physical exam is notable for prominent central (abdominal) obesity. In addition to medical therapy, the man's physician recommends a regimen of diet and exercise. After six months the man's weight, hemoglobin AlC, serum glucose, and serum lipids are unimproved.
