[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Patent Application No. 61 / 810,468, filed April 10, 2013, and U.S. Provisional Patent Application No. 61 / 925,918, filed January 10, 2014, the contents of each of which are incorporated herein by reference in their entirety. [Background technology]
[0002] Obesity is a chronic disease and a major health concern in modern society. According to the Centers for Disease Control and Prevention (CDC), the United States is in the midst of an obesity epidemic. Approximately 65% of adults in the United States are overweight, 30% are obese, and over 5 million adults are classified as morbidly obese. Another 10 million people are closer to that threshold and at risk for obesity-related health problems. The problem is only growing, with childhood and adolescent obesity having doubled in the past 20 years.
[0003] Existing obesity treatments include diet and exercise; very low calorie diets; behavioral therapy; pharmacotherapy including appetite suppressants, thermogenic drugs, and food absorption inhibitors; mechanical devices such as jaw wiring, waist cords, and balloons; and surgery. However, these existing treatments are not very effective. Adherence to energy-restricted diets is problematic and generally ineffective, and pharmacotherapy is only marginally effective in long-term weight management. In many cases, toxicity and side effects prevent the development of potential anti-obesity drug candidates. Metabolic syndrome (Sutherland et al., Metabolic Syndrome and Related Disorders 2:82-104 (2004); Esposito et al., Nutr. Metab. Cardiovasc. Dis. 14:228-232 (2004)) is associated with obesity and is characterized by a constellation of metabolic risk factors including: 1) abdominal obesity (excess adipose tissue in and around the abdomen); 2) atherogenic dyslipidemia (high triglycerides; low HDL cholesterol and high LDL cholesterol); 3) elevated blood pressure; 4) insulin resistance or impaired glucose tolerance; 5) a prothrombotic state (e.g., high fibrinogen or plasminogen activator inhibitor-1 in the blood); and 6) a proinflammatory state (e.g., elevated CRP in the blood). Metabolic syndrome is becoming increasingly prevalent in developed countries and is closely associated with the risk of coronary heart disease (Malik et al., Circulation 110:1245-1250 (2004); Irabarren et al., J. Am. Coll. Cardiol. 48:1800-1807 (2006)).
[0004] Cardiometabolic syndrome includes obesity-related metabolic disorders and atherosclerosis. Cardiometabolic disorders also promote arterial and valvular calcification, which can result in acute myocardial infarction and aortic stenosis, which are devastating clinical complications. Diabetes also causes chronic kidney disease, which also leads to cardiovascular ectopic calcification and acute myocardial infarction. Collectively, several key components of cardiometabolic syndrome, which develop through interrelated mechanisms, promote each other through local or systemic inflammation. Furthermore, lack of patient adherence to prescribed drug therapy represents a huge challenge for the global health care community. In the United States alone, avoidable medical expenditures were estimated at $300 billion in 2009. With blockbuster drugs expiring on patent, exhausting distribution channels, and cost containment by users, closing this adherence gap is a "must do" for pharmaceutical companies.
[0005] Thus, there is a need for novel compounds and methods for causing, inducing, and / or increasing weight loss, and for treating obesity and metabolic syndrome. The present invention addresses these needs. Summary of the Invention [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] Compounds of the Invention The present invention provides a drug conjugate composition comprising a modified active moiety, a conjugate moiety, and a cleavable linker, where cleavage of the linker occurs substantially in the target tissue to produce a modified active moiety that has reduced efflux from the target tissue compared to the unmodified active moiety. The present invention also provides a composition comprising the modified active moiety.
[0012] The conjugate moiety used depends on the biological requirements, such as the pharmacokinetic and pharmacodynamic properties of the active moiety, as well as knowledge of the disease state, as well as the physicochemical properties of both the conjugate moiety and the active moiety. A person skilled in the art will be able to select an appropriate conjugate moiety based on the above considerations. The conjugate moiety is used to deliver small molecule active moieties or larger molecule active moieties, such as proteins, peptides or oligonucleotides.
[0013] The conjugate moiety improves the delivery of the active moiety to the target. The conjugate moiety is selected to maximize the bioavailability of the active moiety; optimize the onset, duration and delivery rate of the active moiety; and maintain the concentration of the active moiety in the therapeutic range in the target tissue for as long as required for effective treatment. The conjugate moiety can also help minimize adverse side effects of the active moiety. Thus, the conjugate moiety prolongs the pharmacological activity of the active moiety, stabilizes labile active moieties from chemical and proteolytic degradation, minimizes side effects, increases solubility, and delivers the active moiety to specific cells or tissues.
[0014] Other properties of the conjugate moiety to be considered are that the conjugate moiety has minimal immunogenicity and toxicity or is non-immunogenic and non-toxic. The molecular weight of the conjugate moiety should be large enough to avoid rapid removal by renal ultrafiltration and small enough to prevent undesirable accumulation in the body. In some embodiments, the conjugate moiety is hydrophilic and biodegradable. Non-biodegradable conjugate moieties are also suitable in the compositions and methods of the present invention. The conjugate moiety should be capable of carrying the required amount of the active moiety and preventing premature metabolism of the active moiety during transport to the target tissue.
[0015] Preferred conjugates include all forms of polymers, i.e., synthetic and natural product-related polymers, including peptides, polysaccharides, polynucleic acids, antibodies and aptamers. In a preferred embodiment, the conjugate is a synthetic polymer. Preferred polymers of the present invention are described in U.S. Pat. Nos. 4,997,878 to Bock et al., 5,037,883 to Kopecek et al., 5,258,453 to Kopecek et al., 6,464,850 to Zhang et al., and 6,803,438 to Brocchini et al., each of which is incorporated by reference in its entirety. Additional preferred polymers are described in Subr et al., J Controlled Release, 18, 123-132 (1992). In some embodiments, the synthesis method of the polymer may result in the coupling of two or more polymer chains, which may increase the weight average molecular weight of the polymer conjugate. It is further understood that when this coupling occurs, the bond is biodegradable.
[0016] The active moiety may be any compound or molecule that produces a therapeutic effect in a subject. In some embodiments, the compound or molecule has a molecular weight of 2000 daltons or less, 1500 daltons or less, 1000 daltons or less, 500 daltons or less, or 250 daltons or less. In some embodiments, the compound or molecule is a MetAP2 inhibitor. In some embodiments, the compound or molecule is fumagillin, fumagillol, or an analog, derivative, salt, or ester thereof. The compound or molecule selected depends on the condition or disease being treated. In some embodiments, more than one active moiety may be used. In some embodiments, an active moiety and an inactive "capping" moiety may be used. In some embodiments, the condition being treated is obesity. In the compositions of the present invention, the conjugate moiety is linked to the active moiety via a linker. Any linker structure known in the art may be used to link the modified active moiety to the conjugate moiety. The linker used depends on the physiological condition of the target tissue, the properties of the active moiety being optimized, and the cleavage mechanism. D'Souza et al. review various linkers, including those that function via proteolytic cleavage: "Release from Polymeric Prodrugs: Linkages and Their Degradation" J. Pharm. Sci., 93, 1962-1979 (2004). Blencoe et al. describe various self-immolative linkers: "Self-immolative linkers in polymeric delivery systems" Polym. Chem. 2, 773-790 (2011). Ducry et al. review linkers in Bioconj. Chem. 21, 5-13 (2010) "Antibody-Drug Conjugates: Linking Cytotoxic Payloads to Monoclonal Antibodies".Peptide linkers suitable for cleavage by matrix metalloproteins (MMPs) are described in Chau et al., “Antitumor efficacy of a novel polymer-peptide-drug conjugate in human tumor xenograft models,” Int. J. Cancer 118, 1519-1526 (2006), and in Chau et al., U.S. Patent Application Publication No. 2004 / 0116348. Other linker chemistries suitable for the compositions of the invention are set forth in Shiose et al., Biol. Pharm. Bull. 30(12) 2365-2370 (2007); Shiose et al., Bioconjugate Chem. 20(1) 60-70 (2009); U.S. Pat. Nos. 7,553,816 to Senter; 7,223,837 to De Groot; 6,759,509 to King; 6,835,807 to Susaki; 6,436,912 to Susaki; and 7,943,569 to Gemeinhart.
[0017] In some embodiments, the linker is a peptide linker. Preferred peptide linkers are described in U.S. Patent No. 6,835,807 to Susaki et al., U.S. Patent No. 6,291,671 to Inoue et al., U.S. Patent No. 6,811,996 to Inoue et al., U.S. Patent No. 7,041,818 to Susaki et al., U.S. Patent No. 7,091,186 to Senter et al., and U.S. Patent No. 7,553,816 to Senter et al., each of which is incorporated by reference in its entirety. Additional preferred peptides and their truncations are described in Shiose et al., Biol.Pharm.Bull.30(12)2365-2370(2007) and Shiose et al., Bioconjugate Chem.20(1)60-70(2009). Peptide linkers suitable for cleavage by matrix metalloproteins (MMPs) are described in Chau et al., “Antitumor efficacy of a novel polymer-peptide-drug conjugate in human tumor xenograft models” Int. J. Cancer 118, 1519-1526 (2006), and Chau et al., U.S. Patent Application Publication No. 2004 / 0116348.
[0018] The linker may be cleaved by any mechanism known in the art. For example, the linker may be designed for proteolytic or intracellular proteolytic cleavage. In some embodiments, the linker is designed such that there is no cleavage of the linker in plasma or the cleavage rate is very low in plasma. Preferred linker structures are described in more detail below.
[0019] In some embodiments, the linker is structured to be preferentially cleaved in diseased tissue. Since hydrolases exist in both normal and diseased tissues, the linker should be cleaved by hydrolases that are more active and / or more abundant in diseased tissue. For example, tumors generally have upregulated metabolic rates and overexpress proteases, including cathepsins in particular. The role of upregulation and proteases in cancer is described in Mason et al., Trends in Cell Biology 21,228-237 (2011).
[0020] In one embodiment, a class of modified active moieties are those that bind irreversibly to their targets; i.e., after release from the complex, the active moiety is covalently bound to the biochemical target. Once bound, the active moiety cannot diffuse or be transported out of the cell. In the case of irreversible binding, the rate of binding of the small molecule to the target, K, must be met for targeting to occur. rev1 is the rate of small molecule efflux, k sm-1 A high rate of efflux relative to small molecule binding would establish an equilibrium of the small molecule between the plasma and intracellular compartments, eliminating the advantage of intracellular versus extracellular delivery.
[0021] In another embodiment, a class of modified active moieties are those that bind reversibly to their targets. In the case of reversible binding, the equilibrium constant for small molecule binding to a target, K=k rev1 / k rev-1 should be large, and the "on-rate", k rev1 is the rate of small molecule efflux, k sm-1should be high relative to the rate of small molecule binding. A high rate of efflux relative to the rate of small molecule binding will establish an equilibrium of the small molecule between the plasma and intracellular compartments, eliminating the advantage of intracellular delivery over extracellular delivery. Such a relationship is shown diagrammatically below, where: [PC] = concentration of polymer conjugate; [SM] = concentration of free small molecule; plasma = plasma concentration; icell = concentration within a cell; icell-target = small molecule reversibly bound to a target within a cell; and inactive = inactive metabolite of the small molecule. In one embodiment, k rev-1 When =0, the moiety irreversibly binds to the target.
[0022] [ka]
[0023] In another embodiment, the class of modified active moieties are those that have very high equilibrium constants and high "on-rates" relative to efflux. In another embodiment, the class of modified active moieties are those that undergo intracellular metabolism at high rates relative to efflux.
[0024] In some embodiments, the modification to the active moiety is achieved by using a linker that has a structure such that upon cleavage, a fragment of the linker remains attached to the active moiety. The fragment can either change the molecular weight, hydrophobicity, polar surface area, or charge of the active moiety, thereby generating a modified active moiety that has reduced efflux from target cells compared to the unmodified active moiety. For example, a MetAP2 inhibitory active moiety can be coupled via a linker as described herein, resulting in a complex that, upon cleavage of the linker, generates an active moiety (modified active moiety) with a fragment of the linker attached thereto. The modified active moiety as described herein can have reduced efflux from cells compared to the unmodified active moiety, resulting in a modified active moiety with better efficacy relative to the parent small molecule, and better efficacy relative to the parent small molecule, and a better pharmacokinetic profile.

[0285] Other active moieties that can be modified for use in the complexes of the present invention include the following structures:
[0286]
Chem.
[0287] In some embodiments, the active moiety is an anti-obesity compound. In other embodiments, the active moiety is a molecule that inhibits methionine aminopeptidase-2 (MetAP2), such as fumagillin, fumagillol, or its analogs, derivatives, salts or esters. Furthermore, preferred MetAP2 inhibitors are described in U.S. Patent No. 6,242,494 to Craig et al., U.S. Patent No. 6,063,812 to Hong et al., U.S. Patent No. 6,887,863 to Craig et al., U.S. Patent No. 7,030,262 to BaMaung et al., and U.S. Patent No. 7,491,718 to Comess et al., each of which is incorporated by reference in its entirety. Additional preferred MetAP2 inhibitors include those described by Wang et al., “Correlation of tumor growth suppression and methionine aminopeptidase-2 activity blockade using an orally active inhibitor,” PNAS 105(6)1838-1843 (2008); Lee et al., “Design, Synthesis, and Antiangiogenic Effects of a Series of Potent Novel Fumagillin Analogues,” Chem. Pharm. Bull. 55(7)1024-1029 (2007); Jeong et al., “Total synthesis and antioxidant activity of cyclopentane analogues of fumagillol,” Bioorganic and Medicinal Chemistry Letters 15,3580-3583 (2005); and Arico-Muendel et al., “Carbamate Analogues of Fumagillin as Potent, Targeted Inhibitors of Methionine Aminopeptidase-2," J. Med. Chem. 52, 8047-8056 (2009); and WO 2010 / 003475 to Heinrich et al.
[0288] Fumagillin is a small molecule used as an antibacterial and antiprotozoal agent. Its physicochemical properties and methods of preparation are known (see U.S. Pat. No. 2,803,586 and Turner, JR et al., The Stereochemistry of Fumagillin, Proc. Natl. Acad. Sci. 48, 733-735 (1962)). The fermentation product, fumagillin, is hydrolyzed to give the alcohol fumagillol, which may be converted to various derivatives, including carbamoyl fumagillol, MW325. The synthesis and preparation of carbamoyl fumagillol and several small molecule derivatives are described in U.S. Pat. No. 5,166,172.
[0289] Fumagillin and related compounds are believed to exert their biological effects through inhibition of MetAP2, an enzyme that removes N-terminal methionine from nascent cellular proteins (see Tucker, LA et al., "Ectopic Expression of Methionine Aminopeptidase-2 Causes Cell Transformation and Stimulates Proliferation," Oncogene 27, 3967 (2008)).
[0290] Carbamoyl fumagillol and derivatives, as well as other MetAP2 inhibitors, have shown therapeutic efficacy in preclinical and clinical studies. These compounds inhibit cell proliferation and angiogenesis, as described in U.S. Pat. No. 5,166,172. Fumagillin analogs or derivatives, such as CKD-732 and PI-2458, have been well studied in various systems, as described in Bernier et al., "Fumagillin class inhibitors of methionine aminopeptidase-2," Drugs of the Future 30(5):497-508, 2005.
[0291] The anti-obesity effects of fumagillin and its analogs are known. Rupnick et al., "Adipose tissue mass can be regulated through the vasculature," PNAS 99, 10730-10735, 2002, describes weight loss in ob / ob mice with TNP-470 at daily doses ranging from 2.5 mg / kg to 10 mg / kg. Brakenhielm describes the prevention of obesity with TNP-470 at doses of 15 or 20 mg / kg every other day: "The Angiogenesis Inhibitor, TNP-470, Prevents Diet-Induced and Genetic Obesity in Mice," Circulation Research 94:1579-1588, 2004. Kim et al., "Assessment of the anti-obesity effects of the TNP-470 analog, CKD-732," J Molecular Endocrinology 38, 455-465, 2007, describe weight loss in C57BL / 6J mice and SD rats at a dose of 5 mg / kg / day. Lijnen et al., "Fumagillin reduces adipose tissue formation in murine models of nutritionally induced obesity," Obesity 12, 2241-2246, 2010, describe that daily oral delivery of 1 mg / kg fumagillin results in weight loss in C57BL / 6 mice.
[0292] One of these derivatives, chloroacetylcarbamoyl fumagillol (TNP-470), has been studied extensively. (See H. Mann-Steinberg et al., "TNP-470: The Resurrection of the First Synthetic Angiogenesis Inhibitor", Chapter 35 in Folkman and Figg, Angiogenesis: An Integrative Approach from Science to Medicine, Springer NY (2008)). TNP-470 has shown activity against many cancers, including lung, cervical, ovarian, breast and colon cancers. Due to dose-limiting neurotoxicity, TNP-470 has been tested using multiple dosing regimens, but these attempts to limit its toxicity have been unsuccessful. Thus, TNP-470 has proven too toxic for use in humans. TNP-470 has a short half-life and requires prolonged intravenous administration for therapeutic use. Carbamoyl fumagillol, a metabolite of TNP-470, has a half-life of 12 minutes in humans (see Herbst et al., "Safety and Pharmacokinetic Effects of TNP-470, an Angiogenesis Inhibitor, Combined with Paclitaxel in Patients with Solid Tumors: Evidence for Activity in Non-Small-Cell Lung Cancer," Journal of Clinical Oncology 20(22)4440-4447 (2002). Furthermore, fumagillin and its derivatives are hydrophobic and difficult to formulate.
[0293] Despite the known usefulness of fumagillin derivatives, their use in therapy has not been successful due to the inability to overcome the problems of low water solubility, short half-life value, and neurotoxic side effects of these compounds.Based on the previously observed dose-limiting neurotoxicity, the MTD of TNP-470 in combination with paclitaxel has been determined to be 60 mg / m2 administered three times a week: Herbst et al., "Safety and pharmacokinetic effects of TNP-470, an angiogenesis inhibitor, combined with paclitaxel in patients with solid tumors: evidence for activity in non-small-cell lung Cancer", Journal of Clinical Oncology 20, 4440-4447, 2002. Similarly, Shin et al., "A Phase 1 pharmacokinetic and pharmacodynamics study of CKD-732, an antiangiogenic agent, in patients with refractory solid cancer"Investigational New Drugs 28, 650-658, 2010" reported that the MTD of CKD-732 is 15 mg / m2 / day, administered on a 4-day schedule due to confusion and insomnia. Thus, the compounds of the present invention are more potent, exhibit reduced toxicity (lower neurotoxicity), have improved water solubility, are more stable, and / or have a longer half-life (serum half-life) than currently known fumagillin derivatives.
[0294] The term "reduced toxicity" as used herein has its ordinary meaning as understood by one of ordinary skill in the art. By way of example only and not intended to limit the meaning of the term in any way, administration of a fumagillin analog conjugate results in fewer side effects in an open field test in mice compared to administration of the fumagillin analog alone.
[0295] The phrase "improved water solubility" has its ordinary meaning as understood by those of skill in the art. By way of example only and not intended to limit the meaning of the term in any way, the following description of the term is instructive: the fumagillin analog becomes more soluble in water by being covalently incorporated into the complex than the unbound fumagillin analog would be soluble in water alone.
[0296] The phrase "longer half-life" has its ordinary meaning as understood by one of ordinary skill in the art. By way of example only and not intended to limit the meaning of the term in any way, the following description of the term is instructive: any appreciable increase in the length of time required to deactivate a fumagillin conjugate, either in vivo or in vitro, as compared to the half-life of the fumagillin analog alone, either in vivo or in vitro.
[0297] Without being bound by any theory, the nonenzymatic action of MetAP2, which inhibits the activity of extracellular signal-regulated kinases 1 and 2 (ERK1 / 2), may be important, as may the binding of the eukaryotic translation initiation factor, eIF, by MetAP2. Cellular responses to MetAP2 inhibition, reflecting potential ERK-related processes, may include suppression of sterol regulatory element-binding protein (SREBP) activity, leading to reduced lipid and cholesterol biosynthesis. Interestingly, changes in the expression patterns of liver and adipose tissue genes after long-term (approximately 9 months) fumagillin exposure suggest that inhibition of MetAP2 may alter the relative abundance of factors involved in inflammation, consistent with a reduction in ERK-dependent cellular processes. The putative mechanism of MetAP2 inhibition, leading to the mobilization of stored fat as an energy source by the body and the catabolism of free fatty acids, is supported by the changes in plasma β-hydroxybutyrate, adiponectin, leptin, and FGF21 observed in previous studies. The increase in the levels of adiponectin and FGF21, the major catabolic hormones, accompanied by the appearance of ketone bodies (β-hydroxybutyrate), suggests that the inhibition of MetAP2 by the compound of the present invention, conjugated or modified fumagillin, fumagillol, or its analogs, derivatives, salts or esters, promotes energy expenditure, fat utilization, and lipid excretion. The reduction in leptin observed in previous studies and the studies provided herein is also consistent with the reduction in total adipose tissue and negative energy balance. It is also possible that the compound of the present invention, conjugated or modified fumagillin, fumagillol, or its analogs, derivatives, salts or esters, forms a covalent bond with MetAP2, thereby irreversibly inhibiting and shutting down existing enzymes until a pool of newly produced MetAP2 is generated in target tissues (e.g., liver and adipose tissue).
[0298] In certain embodiments, the conjugated or modified fumagillin, fumagillol, or analogs, derivatives, salts, or esters thereof of the compounds of the invention have the structure of the following formula, for example, as shown in Table 1:

In certain embodiments, a straight or branched chain alkyl has 30 or fewer carbon atoms in its backbone (e.g., C for straight chain). 1 -C 30 , C for branched chains 3 -C 30 ), and more preferably have 20 or fewer carbon atoms. Likewise, certain cycloalkyls have from 3-10 carbon atoms in their ring structure, and can have 5, 6 or 7 carbons in the ring structure.
[0313] Unless the number of carbon atoms is otherwise specified, "lower alkyl" as used herein refers to an alkyl group as defined above, but having 1-10 carbon atoms, or 1-6 carbon atoms in its main chain structure, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, and tert-butyl. Similarly, "lower alkenyl" and "lower alkynyl" have similar chain lengths. Throughout this specification, certain alkyl groups are lower alkyls.

Any recitation of a specific isomer is merely exemplary (e.g., recitation of a trans isomer also includes the cis isomer).
[0358] For example, if a particular enantiomer of a compound of the invention is desired, it can be prepared by asymmetric synthesis or derivatization with a chiral auxiliary, in which case the resulting mixture of diastereomers can be separated and the pure desired enantiomer obtained by cleavage of the auxiliary. Alternatively, if the molecule contains a basic functional group, such as an amino group, or an acidic functional group, such as a carboxyl group, the salt of the diastereomer can be formed with a suitable optically active acid or base, and the diastereomers so formed can then be resolved by fractional crystallization or chromatographic means known in the art, followed by recovery of the pure enantiomer.

[0375] The present invention also provides a method for reducing body weight in a subject in need thereof, comprising administering to the subject a therapeutically effective amount of at least one compound of the present invention to reduce body weight. In some embodiments, the subject is overweight or obese. In some embodiments, the subject is in need of reducing excess adipose tissue.
[0376] Obesity and being overweight refer to a subject having an excess of fat relative to their lean body mass. Excessive fat accumulation is associated with an increase in the size (hypertrophy or adiposity) and number (hyperplasia) of adipose tissue cells. Obesity can be due to a variety of factors, whether genetic (e.g. Prader-Willi syndrome) or environmental. Obesity is measured in various ways in terms of absolute body weight, weight-to-weight ratio, degree of excess body fat, distribution of visceral or subcutaneous fat, and social and aesthetic norms. A common measure of body fat is the Body Mass Index (BMI). BMI represents the ratio of body weight (expressed in kilograms) to the square of height (expressed in meters). Body Mass Index can be calculated accurately using the following formula: SI units: BMI = weight (kg) / (height) 2 (m 2 ), or in US units: BMI = (weight (lbs) * 703) / (height 2 (inch 2 ).
[0377] As used herein, "overweight" is defined as a weight gain or weight exceeding 25 kg / m2 in an otherwise healthy adult. 2 ~29.9kg / m 2 As used herein, "obesity" refers to a condition in which an otherwise healthy adult has a BMI of 30 kg / m 2Obesity is defined as a condition in which the body mass index (BMI) is greater than or equal to 35 kg / m2. 2 Adults with a BMI above 40 to 44.9 kg / m are considered to be "severely obese" or "severely obese." 2 Adults with a BMI of 35 kg / m 2 Adults with a BMI above 45 kg / m2 and who have at least one obesity-related health condition are referred to as "morbidly obese" or "morbidly obese." 2 Adults with a BMI above this level are termed "super obese" or "super obese." In children, the definition of overweight and obesity takes into account the effects of age and sex on body fat.
[0378] Different countries may define obesity and overweight by different BMIs. The term "obesity" is intended to encompass definitions in all countries. For example, in Asians, the increased risk associated with obesity occurs at lower body mass index (BMI). In Asian countries, including Japan, "obesity" is defined as a condition in which a subject with at least one obesity-induced or obesity-related comorbidity that requires or would be improved by weight loss has a BMI of 25.0 kg / m2 or more. 2 It refers to the condition of having a BMI above 10. South and Central Americans tend to be classified as more similar to Asians than Europeans or North Americans.
[0379] BMI cannot account for the fact that excess adipose tissue occurs selectively in different parts of the body, and the development of adipose tissue may be more dangerous in some parts of the body than in other parts of the body. For example, "central obesity", which is typically associated with an "apple-shaped" body type, is caused by excess fat accumulation, especially in the abdominal region, including abdominal fat and visceral fat, and has a higher risk of comorbidities than "peripheral obesity", which is typically associated with a "pear-shaped" body type, and is caused by excess fat accumulation, especially in the waist. Measurement of waist / hip ratio (WHR) can be used as an index of central obesity. The minimum WHR indicating central obesity has been set in various ways, and adults with central obesity typically have a WHR of about 0.85 or more for women and about 0.9 or more for men.
[0380] Disease assessment is performed by standard methods known in the art, such as by monitoring appropriate markers. For example, for obesity, the following markers may be monitored: weight, BMI, body composition survey, body fat distribution, central fat distribution, food or calorie intake, behavioral measures of hunger and satiety, metabolic rate, and obesity-related comorbidities.
[0381] A method for determining whether a subject is overweight or obese, which describes the ratio of excess adipose tissue to lean body mass, includes obtaining information of the subject's body composition. Body composition can be obtained by measuring the thickness of subcutaneous fat at multiple locations on the body, such as the abdomen, subscapular region, arms, buttocks, and thighs. These measurements are then used to estimate total body fat with a margin of error of about 4 percentage points. Another method is bioelectrical impedance analysis (BIA), which uses the resistance of an electric current passing through the body to estimate body fat. Another method uses a large tank of water to measure body buoyancy. More body fat results in more buoyancy and more muscle mass results in a tendency to sink. Another method is fan beam dual energy x-ray absorptiometry (DEXA). DEXA can non-invasively measure body composition, particularly total body fat and / or regional body fat mass. MRI can also be used to non-invasively measure body composition.
[0382] For all methods described herein, reference to the compounds of the present invention also includes compositions, such as pharmaceutical compositions described herein, that contain one or more of these compounds. These compositions may further include suitable excipients, such as pharma- ceutically acceptable excipients, including, for example, buffers known in the art. The present invention can be used alone or in combination with other conventional therapeutic methods.
[0383] A subject in need of the treatment provided by the present invention may have (i.e., may be diagnosed with or suffer from) at least one obesity-induced or obesity-related comorbidity, i.e., diseases and other adverse health conditions associated with, exacerbated by, or caused by, being overweight or obese. In other embodiments, a subject may have at least two obesity-induced or obesity-related comorbidities.
[0384] Obesity-induced or obesity-related comorbidities include, but are not limited to, diabetes mellitus, non-insulin-dependent type II diabetes mellitus, impaired glucose tolerance, impaired fasting glucose, dysglycaemia, elevated plasma insulin concentration, insulin resistance syndrome, hyperlipidemia, dyslipidemia, elevated free fatty acids, hypertension, hyperuricemia, gout, coronary artery disease, heart disease, myocardial infarction, angina pectoris, microvascular disease, sleep apnea, obstructive sleep apnea, Pickwickian syndrome, fatty liver; cerebral infarction, stroke, cerebral thrombosis, respiratory complications, cholelithiasis, gallbladder disease, kidney disease, gastroesophageal reflux, stress urinary incontinence, arteriosclerosis, heart disease, heart rhythm abnormalities, arrhythmias, transient ischemic attacks, orthopedic disorders, osteoarthritis, osteoarthritis, lumbodynia, menstrual disorders, hormonal imbalances, endocrine disorders, and infertility.

[0391] The present invention also provides a method for reducing adipocytes in a subject in need thereof, comprising administering to the subject a therapeutically effective amount of at least one compound of the present invention to reduce adipocytes or adipose tissue. The present invention also provides a method for preventing an increase in adipocytes in a subject at risk thereof, comprising administering to the subject a therapeutically effective amount of at least one compound of the present invention to prevent an increase in adipocytes. Reducing adipocytes means reducing the number or reducing the size (fat mass) of adipocytes. Preventing an increase in adipocytes means reducing or maintaining the number of adipocytes or reducing or maintaining the size of adipocytes. In some embodiments, administering a compound of the present invention shrinks adipocytes in a subject in need thereof. The adipocytes can be white adipose tissue or brown adipose tissue.
[0392] The present invention also provides a method for reducing food intake in a subject in need thereof, comprising administering to the subject a therapeutically effective amount of at least one compound of the present invention to reduce food intake.
[0393] A reduction in food intake means a reduction in daily food intake. The reduction in daily food intake can be about 5% to about 50% (e.g., about 5%, about 10%, about 20%, about 30%, about 40%, or about 50%). Based on a daily diet of 2000 kcal, the reduction is about 100 kcal to about 1000 kcal per day (e.g., about 100 kcal, about 200 kcal, about 400 kcal, about 600 kcal, about 800 kcal, or about 1000 kcal).
[0394] The present invention also provides a method of reducing hunger in a subject in need thereof, comprising administering to the subject a therapeutically effective amount of at least one compound of the present invention to reduce hunger. The subject may also have a reduced food intake.
[0395] Hunger can be assessed in the fasted state using a 10-point visual analog scale (VAS), which is commonly used in appetite studies. See Flint et al., Int. J. Obes. Relat. Metab. Disord. 24(1):38-48, 2000. Specifically, subjects are asked to rate their overall hunger over the previous two days on a scale of 1 to 10, with 10 being extremely hungry and 1 being not hungry at all.
[0396] The methods of the present invention can also reduce waist circumference in a subject in need thereof. Waist circumference is assessed using a tape measure placed abdominally 1 cm above the iliac crest. A subject of the present invention may have a reduction in waist circumference of about 1 inch (2.54 cm) to about 20 inches (50.8 cm) (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20 inches (2.54 cm, 5.08 cm, 7.62 cm, 10.16 cm, 12.7 cm, 15.24 cm, 17.78 cm, 20.32 cm, 22.86 cm, 25.4 cm, 27.94 cm, 30.48 cm, 33.02 cm, 35.56 cm, 38.1 cm, 40.64 cm, 43.18 cm, 45.72 cm, 48.26 cm, or 50.8 cm).
[0397] In the method of the present invention, the administration of the compound results in a reduction in body fat and a substantial maintenance of muscle mass in the patient. In some embodiments, the administration of the compound promotes fat oxidation in the patient, compared to the patient who is only on a restricted food intake regimen. For example, provided herein is a method for reducing body fat in a patient in need thereof. Such a patient may maintain substantially more muscle mass, compared to the reduction in body fat in a patient who is only on an energy restricted diet regimen.
[0398] The present invention also provides a method for improving surgical outcomes in a subject in need thereof, comprising administering to the subject a therapeutically effective amount of at least one compound of the present invention prior to surgery to improve surgical outcomes. In some embodiments, the administration reduces liver and / or abdominal fat in the patient and improves surgical outcomes. In some embodiments, the surgery is not an emergency surgery. Such surgery may include bariatric surgery, cardiovascular surgery, abdominal surgery, or orthopedic surgery.
[0399] A "patient" or "subject" as used herein can refer to a human or non-human subject. In some embodiments, the subject is a vertebrate. In some embodiments, the vertebrate is a mammal. Mammals include, but are not limited to, farm animals, sport animals, pets, primates (including humans), horses, dogs, cats, mice and rats. In some embodiments, the mammal is a human.
[0400] As used herein, a "subject in need thereof" is a subject who is overweight or obese (with or without one or more comorbidities), or who is at high risk relative to the general population for becoming overweight or developing obesity. In some embodiments, a subject in need thereof is one who is overweight or obese (with or without one or more comorbidities), or who is at high risk relative to the general population for becoming overweight or developing obesity. 2 In some embodiments, the subject in need thereof is a patient who is overweight or obese, or at high risk of becoming overweight or developing obesity relative to the general population, and who does not suffer from or has not been diagnosed with a disorder selected from the group consisting of cancer, hyperproliferative disorders, retinal neovascularization due to macular degeneration, psoriasis and pyogenic granuloma, rheumatoid, immune and osteoarthritis.
[0401] The term "prophylactic or therapeutic" treatment is art-recognized and includes administration of one or more of the subject compositions to a host. If the treatment is administered prior to clinical signs of an undesirable condition (e.g., a disease or other undesirable condition in a host animal), the treatment is prophylactic (i.e., protects the host from developing the undesirable condition), whereas if the treatment is administered after signs of an undesirable condition, the treatment is therapeutic (i.e., intended to reduce, ameliorate, or stabilize an existing undesirable condition or its side effects).
[0402] As used herein, "treatment" is an approach for obtaining beneficial or desired clinical results. For purposes of this invention, beneficial or desired clinical results include, but are not limited to, one or more of: improving one or more symptoms associated with a disease; reducing its severity; or alleviating it. With respect to obesity, beneficial or desired clinical outcomes include any one or more of the following: reducing or maintaining body weight; controlling (including reducing) food intake or caloric intake; increasing metabolic rate or inhibiting a decrease in metabolic rate; and improving, reducing the severity and / or alleviating any of the disorders associated with obesity, such as, for example, diabetes, non-insulin dependent diabetes mellitus, hyperglycemia, low glucose tolerance, insulin resistance, lipid disorders, dyslipidemia, hyperlipidemia, hypertriglyceridemia, hypercholesterolemia, abdominal obesity, eating disorders, metabolic syndrome, hypertension, osteoarthritis, myocardial infarction, fatty liver disease, steatohepatitis, non-alcoholic steatohepatitis (NASH), non-alcoholic fatty liver disease (NAFLD), stroke and other related diseases; improving the quality of life and / or extending the lifespan of patients with obesity.
[0403] As used herein, "delaying" the onset of obesity means to postpone, prevent, slow down, delay, stabilize, and / or postpone the onset of the disease. This delay can be of various lengths of time, depending on the history of the disease and / or medical history of the subject being treated. As will be apparent to one skilled in the art, a sufficient or significant delay can actually encompass prevention, in that the individual does not develop the disease. For example, one result of delaying onset can be to reduce the body weight of a subject at risk of obesity, compared to the body weight of the subject immediately before administration of the composition described herein. Another result of delaying onset can be to prevent the regain of weight previously lost as a result of diet, exercise, or drug therapy. Another result of delaying onset can be to prevent the onset of obesity in a subject at risk of obesity, if the treatment is administered before the onset of obesity. Another result of delaying onset can be to reduce the occurrence and / or severity of obesity-related disorders in a subject at risk of obesity, if the treatment is administered before the onset of obesity.
[0404] An individual "at risk" of obesity may or may not have detectable disease, and may or may not exhibit detectable disease prior to the implementation of the treatment methods described herein. "At risk" refers to an individual having one or more so-called risk factors, which are measurable parameters that correlate with the development of obesity. Individuals with one or more of these risk factors have a higher probability of being obese than individuals without these risk factors. These risk factors include, but are not limited to, age, diet, physical inactivity, metabolic syndrome, family history of obesity, ethnicity, genetic syndrome, previous medical history (e.g., eating disorders, metabolic syndrome, and obesity), and the presence of precursor diseases (e.g., overweight). For example, a person with a body weight of 25.0 to 30.0 kg / m 2 Otherwise healthy individuals with a BMI less than 25.0 kg / m 2 ~27.0kg / m 2 Individuals with at least one comorbidity who have a BMI below 100% are at risk for obesity.
[0405] "Development" of obesity refers to the onset and / or progression of the disease in an individual, which may be different embodiments of the present invention. Onset of obesity can be detected using standard clinical techniques described herein. Onset may also refer to the progression of the disease, which is not detectable in the early stages. For the purposes of the present invention, progression refers to the biological process of the disease state, where progression is measured by height and weight assessment to estimate BMI, measuring waist circumference, assessing comorbidities, and the onset and / or worsening of obesity complications, such as arteriosclerosis, type II diabetes, polycystic ovarian disease, cardiovascular disease, osteoarthritis, dermatological disorders, hypertension, insulin resistance, hypercholesterolemia, hypertriglyceridemia, and cholelithiasis. These various diagnostic tests are known in the art. "Onset" includes onset, recurrence, and onset. As used herein, "onset" or "onset" of obesity includes initial onset and / or recurrence.
[0406] As used herein, "body weight control" or "body weight improvement" refers to reducing or maintaining body weight in an individual (compared to pre-treatment levels). In some embodiments, body weight is maintained within a generally normal range. Body weight can be reduced by reducing caloric intake and / or reducing body fat stores. In some embodiments, body weight is reduced in an individual by at least about any of 3%, 4%, 5%, 10%, 20%, 30%, 40%, or 50% compared to pre-treatment levels.
[0407] As used herein, "controlling food intake" refers to reducing or maintaining food intake in an individual (compared to pre-treatment levels). In some embodiments, food intake is maintained in a generally normal range. In some embodiments, food intake is reduced by about any of 3%, 4%, 5%, 10%, 20%, 30%, 40%, or 50% in an individual compared to pre-treatment levels.
[0408] A "therapeutically effective amount" of a compound, with respect to use in therapy, refers to the amount of compound in a formulation that, when administered as part of a desired dosing regimen (to a mammal, preferably a human), alleviates the symptoms, ameliorates the condition, or delays or prevents the onset of a disease state, according to clinically acceptable criteria for the disorder or condition being treated or for cosmetic purposes, such as a reasonable benefit / risk ratio applicable to any medical treatment. A "therapeutically effective amount" is synonymous with an "effective dose."
[0409] As used herein, an "effective dosage" or "effective amount" of a drug, compound, or pharmaceutical composition is an amount sufficient to produce a beneficial or desired result. In prophylactic use, beneficial or desired results include results such as eliminating or reducing the risk of, reducing the severity, or delaying the onset of a disease, including biochemical, histological, and / or behavioral signs of the disease, complications of the disease, and intermediate pathological phenotypes manifested during the development of the disease. In therapeutic use, beneficial or desired results include clinical results such as, for example, reducing the intensity, duration, or frequency of attacks of the disease; and reducing one or more signs (biochemical, histological, and / or behavioral) resulting from the disease, including complications of the disease and intermediate pathological phenotypes manifested during the development of the disease; increasing the quality of life of a patient suffering from the disease; reducing the dose of other drugs required to treat the disease; enhancing the effect of another drug therapy; and / or delaying the progression of the disease in a patient. An effective dosage can be administered in one or more administrations. For the purposes of the present invention, an effective dosage of a drug, compound, or pharmaceutical composition is an amount sufficient to achieve prophylactic or therapeutic treatment, either directly or indirectly. As understood in a clinical context, an effective dosage of a drug, compound, or pharmaceutical composition may or may not be achieved in conjunction with another drug, compound, or pharmaceutical composition. Thus, when a desired result can or is achieved in combination with one or more other drugs, an "effective dosage" may be considered in the context of administering one or more therapeutic agents, and may also be considered to administer a single drug in an effective amount. For example, an effective amount of a compound of the present invention for treating obesity is an amount sufficient to treat or ameliorate one or more symptoms associated with obesity.An "effective amount" is an amount sufficient to result in one or more of the following (which may correspond to various embodiments of the present invention): reducing, reducing or controlling body weight; reducing, reducing or controlling food intake; increasing metabolic rate; reducing one or more symptoms resulting from diseases associated with obesity; increasing the quality of life of a patient suffering from obesity; and / or extending lifespan.
[0410] When providing one or more compounds described herein to a subject, the dosage of the compound administered will vary depending on factors such as the subject's age, weight, height, sex, general medical condition, previous medical history, disease progression, route of administration, formulation, and the like.
[0411] The dosage of the compound of the present invention can be empirically determined in an individual who has received one or more doses. The individual is administered increasing doses of the compound of the present invention. To evaluate the effectiveness of the compound of the present invention, markers of disease state can be monitored. It will be clear to those skilled in the art that dosage will vary depending on the individual, stage of disease (e.g., stage of obesity), and previous and concurrent treatments.
[0412] The toxicity and therapeutic efficacy of the compounds of the present invention can be determined by standard pharmaceutical procedures in experimental animals. The toxic dose can be determined as the maximum tolerated dose (MTD) or LD50 (the dose lethal to 50% of the population). The effective dose can be determined as the ED50 (the dose therapeutically effective in 50% of the population) or the dose required to produce some mean change in animals (e.g., the dose required to produce a mean reduction in systolic blood pressure of 10 mmHg in a group of subjects).
[0413] Ideally, the effective dose and the toxic dose are determined in the same species. However, when they are determined in different species, allometric scaling can be used to convert to the effective or toxic dose for the other species. The dose ratio of toxic to therapeutic effects is the therapeutic index, which can be expressed as the LD50 / ED50 ratio. When comparing mice to rats, a commonly accepted scaling factor is 2, with the dose in rats estimated to be half that in mice. Thus, if the toxic dose in rats is 100 mg / kg and the effective dose in mice is 1 mg / kg, the therapeutic index in rats can be calculated as the effective dose in rats is 1 mg / kg / 2, or 0.5 mg / kg, resulting in a therapeutic index of 200. The FDA defines a drug as having a narrow therapeutic window if (a) the difference between the median lethal dose and the median effective dose is less than two-fold; or (b) the difference between the minimum toxic concentration and the minimum effective concentration in the blood is less than two-fold.
[0414] Compounds of the present invention that exhibit high therapeutic indices are preferred. Compounds of the present invention that exhibit toxic side effects can also be used, but care should be taken in designing delivery systems that deliver such compounds of the present invention to the site of affected tissues in order to minimize the possibility of damaging non-infected cells, thereby reducing side effects.
[0415] Data obtained from animal studies can be used to formulate a range of dosages for use in humans. The dosage of such compounds of the invention is preferably a range of blood concentrations that includes the effective dose with little or no toxicity. The dosage can vary within this range depending on the dosage form used and the route of administration utilized. For compounds of the invention with MW less than 1000, the therapeutically effective dose can be initially estimated from cell culture assays, while animal models allow better estimation of doses for conjugates that require linker cleavage to release the active moiety. Such information can be used to more accurately determine useful doses in humans. It is known in the art that conjugation with a polymer dilutes the active moiety activity (the polymer is a diluent). This is illustrated in the mouse dosing model of anticancer drugs shown in the table below.
[0416] [Table 2]
[0417] It is therefore well understood that conjugation with polymers increases the clinical dose if not improves the therapeutic index, as exemplified in the human dosing models of anticancer drugs shown in the table below.
[0418] [Table 3]
[0419] The polymer-conjugated and modified compounds of the present invention surprisingly provide greater efficacy and lower toxicity compared to the unconjugated and / or unmodified parent drug / active moiety.
[0420] For example, the fumagillol complex and modified fumagillol compound of the present invention are surprisingly superior to fumagillol small molecule, and at equimolar doses, they cause increased weight loss in DIO mice.The compounds of the present invention can be used at lower molar doses and less frequent dosing to cause equivalent weight loss.Lower molar doses and reduced dosing frequency reduce systemic drug exposure and systemic drug toxicity.Furthermore, the fumagillol complex and modified fumagillol compound of the present invention provide effects similar to those of fumagillol small molecule, i.e., favorable fat loss and reduced food intake in DIO mice.
[0421] Conventional polymer conjugates dilute activity, increase doses 5-20 fold, and produce only modest changes in therapeutic index (less than 2-fold). In contrast, the polymer conjugated compounds of the present invention surprisingly and unexpectedly increase (greatly improve) the therapeutic index and show increased activity at lower doses.
[0422] In the methods of the present invention, the polymer conjugated compounds of the present invention exhibit less frequent dosing (e.g., q4d: dosing every 4 days, q7d: dosing every 7 days, q8d: dosing every 8 days), reduced doses to at least 84 molar % of fumagillol equivalents, reduced AUC in non-target compartments while the therapeutic index is increased (more than 10-fold).
[0423] In another embodiment, effective dosage, for example, daily dosage of the compound of the present invention is provided herein.For example, a method is provided herein, which comprises administering a dose of the compound of the present invention that is effective for weight loss.For example, in the method described herein, the administration of the compound of the present invention contemplated can comprise administering a dose of about 200mg / day, about 80mg / day, about 40mg / day, about 20mg / day, about 10mg / day, about 5mg / day, about 3mg / day, about 2mg / day, about 1mg / day, about 0.5mg / day, about 0.2mg / day, about 0.05mg / day, about 0.01mg / day, or about 0.001mg / day, regardless of body weight.
[0424] An effective amount of the drug for weight loss in a patient may be administered based on body weight or body surface area and may be about 0.0001 mg / kg to about 5 mg / kg body weight / day. For example, contemplated dosages may be about 0.001 to 5 mg / kg body weight / day, about 0.001 mg / kg to 1 mg / kg body weight / day, about 0.001 mg / kg to 0.1 mg / kg body weight / day, about 0.001 to about 0.010 mg / kg body weight / day, or about 0.007 mg / kg body weight / day.
[0425] The compounds of the invention can be administered in an amount sufficient to reduce the patient's body weight by about 0.5 kg / week to about 1 kg / week (or about 0.5% of body weight per week to about 1% of body weight per week). In some embodiments, the reduction in weekly body weight occurs for the duration of treatment.
[0426] Administration of the compounds of the invention according to the methods of the invention may be continuous or intermittent, depending, for example, on the physiological condition of the patient receiving the administration, whether the purpose of the administration is therapeutic or prophylactic, and other factors known to the skilled practitioner. Administration of the compounds of the invention may be essentially continuous over a preselected period of time, or may be in a series of spaced doses.
[0427] For repeated administration over several days or longer, depending on the condition, treatment is continued until the desired suppression of symptoms or sufficient therapeutic levels are achieved. For example, dosing 1-5 times per week is contemplated. In certain embodiments, the compounds of the invention are administered about every 4 days. Other dosing regimes include 1-5 times per week, every 3-4 days, or less frequent regimes. In some embodiments, the compounds of the invention are administered about once per week, once every 2 weeks, or about 1-4 times per month, depending on the duration of response to drug administration. Intermittent dosing regimes with staggered dosages spaced 2 days up to 7 days or 14 days apart may be used. In some embodiments, treatment may begin with daily dosing, then change to weekly to monthly dosing. The progress of this treatment can be easily monitored by conventional techniques and assays, or by measuring MetAP2 as described in U.S. Pat. No. 6,548,477.
[0428] The frequency of administration can be determined and adjusted over the course of treatment.For example, the frequency of administration can be determined or adjusted based on the type and severity of the disease being treated, whether the purpose of administration of the drug is preventive or therapeutic, previous treatment history, the clinical history of the patient, and response to the drug, and the instructions of the attending physician.Typically, the clinician administers the compound of the present invention until a dosage that achieves the desired result is reached.
[0429] Treatment can continue for as long as desired or can be limited to a short period of time. Suitable treatment periods can be, for example, at least about 1 week, at least about 4 weeks, at least about 1 month, at least about 6 months, at least about 1 year, at least about 2 years, or indefinitely. Treatment periods can end when desired results, such as targeted weight loss, are achieved, for example, about 5% of body weight, about 10% of body weight, about 20% of body weight, about 30% of body weight or more are achieved.

[0560] BocNHCH 2 CH 2 N(Me)CH 2 C(O)NHC(O) 2 -Fumagyl-6-yl (alkylation of N-BOC, N'-methylethylenediamine with chloroacetylcarbamoyl fumagillol):
[0561] [ka]
[0562] A solution of ΤΝΡ-470 (0.2 g) and DIEA (0.105 g) in DMF (3 mL) was cooled to 0 °C. A solution of tert-butyl N-[2-(methylamino)ethyl]carbamate (0.105 g) in DMF (3 mL) was added and the mixture was stirred at 0 °C for 3 h and then overnight.

[0563] Reaction of tert-butyl N-[2-aminoethyl]carbamate with chloroacetylcarbamoyl fumagillol:
[0564] [ka]
[0565] A 30 uL aliquot of a 1 M solution of Boc-ethylenediamine in DMF was added to DMF (270 uL). The solution was cooled to 0° C. and a solution of TNP-470 (48 mg) in DMF (600 uL) was added dropwise over 2 min. The reaction was monitored by LC / MS. The maximum amount of desired alkylation product observed was 34%. Carbamoyl fumagillol was also produced. The ratio of desired product to carbamoyl fumagillol was 1.0 to 0.4. Attempts to isolate the desired product resulted in the isolation of hydantoin and fumagillol. Thus, the desired product could not be isolated due to the rate of decomposition. Thus, TNP-470 could not be alkylated according to the method described.
[0566] In vivo study of DIO C57B16 mice - Body weight change, food intake, and body composition Thirteen-week-old C57B16 male mice (N=6) with an average body weight of 34 g were fed ad libitum with TD.06414, a high-fat diet (Harlan diet) with 60% of Kcal from fat. On study day 1, animals were randomly divided into groups such that the average body weight of each group was 33.9 g. Mice were treated with either phosphate-buffered saline (vehicle), TNP-470, or Compound 16 (subcutaneously in the back). Treatment continued for 31 days at the doses and schedules shown in the table below. Animals were weighed every other day. Food intake was measured once a week. On day 33, macroscopic observations were obtained to determine body composition.
[0567] FIG. 1 compares weight loss in obese DIO mice following treatment with a fumagillol-conjugate compound of the invention (compound 16) or TNP-470 (a synthetic fumagillin analog) at different doses / regimens as listed in Table 2.
[0568] [Table 4]
[0569] The results in FIG. 1 show that the vehicle control group had a weight gain of 16% and the administration of compound 16 in a q4d dosing regimen resulted in a weight loss of 19%. The administration of compound 16 provides both therapeutic and prophylactic effects. Specifically, compound 16 induces or promotes weight loss and prevents weight gain. Compound 16 is superior to TNP-470 in the extent of weight loss. Compound 16 is superior to TNP-470 in that the dose of fumagillol is reduced.
[0570] Table 3 compares body fat composition in obese DIO mice after treatment with Compound 16 or TNP-470 at different doses / regimens as described herein. Analysis was performed macroscopically on day 33. Total fat as a percentage of body weight in the vehicle group was 13.2%, while total mortality in the Compound 16-treated group was 8.2% (1 mg / kg, qod) or 5.6% (6 mg / kg, q4d).
[0571] [Table 5]
[0572] Figure 2 compares the average daily food intake in obese DIO mice after treatment with compound 16 or TNP-470 at different doses / regimens. The results in Figure 2 show reduced food intake after treatment with compound 16, which produces a greater reduction in food intake than TNP-470.
[0573] Figure 3 compares body composition (fat vs. body weight) in obese DIO mice after treatment with Compound 16 or TNP-470 at different doses / regimens. The results in Figure 3 show that reduced body weight directly correlates with reduced fat.
[0574] In vivo study of DIO C57B16 mice - body weight change, food intake, glucose tolerance, and body composition dose response Fifteen week old male C57B16 mice (N=6) with an average body weight of 42g were fed ad libitum with TD.06414, a high fat diet (Harlan diet) with 60% of Kcal composed of fat. On the first day of the study, animals were treated with either phosphate buffered saline (vehicle) or Compound 16 at different doses (subcutaneously in the back). Treatment continued for 29 days at the doses and schedules shown in the table below. Animals were weighed every other day. Food intake was measured once a week. On the 24th day (mice had been most recently treated with Compound 16 on the 21st day), an overnight fasting intraperitoneal (IP) glucose tolerance test (GTT) was performed on the vehicle and the four Compound 16-treated groups. Each animal was weighed and a baseline fasting glucose measurement was collected. Each animal was given a dose of 1 gram per kilo of glucose as a 25% solution by intraperitoneal injection. Blood glucose levels were measured 15, 30, 60, 90, and 120 min after intraperitoneal glucose administration (via tail vein blood samples using the AlphaTRAK blood glucose monitoring system (includes glucose meter and test strips) commercially available from Abbott Laboratories (North Chicago, Illinois, USA). The AlphaTRAK instrument displays results ranging from 20 to 750 mg / dL (1.1 to 41.7 mmol / L). On day 32 (mice were most recently dosed on day 29), animals were fasted for 3 h, weighed, blood was collected by cardiac puncture, and macroscopic findings were obtained to determine body composition. Blood analysis was performed by Idexx laboratories. Blood glucose was 278, 290, 265, 259, and 227 mg / dL for doses 0, 0.2, 0.6, 2.0, and 6.0, respectively. Blood urea nitrogen (BUN) was 21.8, 22.0, 19.7, 15.3, and 16.5 for doses of 0, 0.2, 0.6, 2.0, and 6.0, respectively.
[0575] Table 4 shows blood glucose levels as a function of time and dose of Compound 16. Table 4 shows that higher doses of Compound 16 resulted in lower blood glucose levels, even at the lowest dose of 0.2 mg / kg, and these results are shown in Figure 4.
[0576] [Table 6]
[0577] Table 5 shows that increasing doses of Compound 16 resulted in significantly improved weight loss at doses greater than 0.2 mg / kg q4d. Table 6 shows that doses of 2 mg / kg q4d and 6 mg / kg q4d led to significant decreases in food intake compared to vehicle controls, and that food intake was dose-responsive. From days 9-29, weekly food intake for the 2 mg / kg group was 90% of vehicle, while food intake for the 6 mg / kg group was 75% of vehicle.
[0578] [Table 7]
[0579] [Table 8]
[0580] Table 7 shows that adipose tissue is lost before other tissues, with control mice having approximately 13% fat, compared to 11% and 10% fat in the 2 mg / kg q4d and 6 mg / kg q4d groups, respectively.
[0581] [Table 9]
[0582] The results in Figure 5 show that weight loss is enhanced following treatment with Compound 16 at doses of 0.6 mg / kg and above using a q4d schedule. Weight loss was dose-responsive, with greater weight loss with increasing dose.
[0583] The results in Table 8 show a decrease in cholesterol, triglycerides, HDL, LDL, and the HDL / LDL ratio associated with increasing doses of Compound 16. These results are shown in FIG.
[0584] [Table 10]
[0585] The results in Table 9 show favorable changes in alkaline phosphatase, SGPT, SGOT, and CPK associated with increasing doses of Compound 16.
[0586] [Table 11]
[0587] Working Example Fifteen week old male C57B16 mice (N=6) with an average body weight of 42g were fed ad libitum with TD.06414, a high fat diet (Harlan diet) with 60% of Kcal composed of fat. On study day 1, animals were treated with either phosphate buffered saline (vehicle) or a dose of 2mg / kg of Compound 16, 28, 29, or 30, or 6mg / kg of Compound 31 on a q4d schedule (dorsal, subcutaneous administration). Animals were weighed every other day. Figure 10 compares weight loss in obese DIO mice after 23 days of treatment with various conjugates of the invention. The results in Figure 10 show that variation in the linker alone results in varying degrees of weight loss.
[0588] Working Example Male Sprague Dawley rats (N=3) aged 9-10 weeks with an average body weight of 300 g were fed a standard rodent diet (PharmaServ lab diet 5001) ad libitum. Figure 7 - Rats were treated with either 100 mg / kg or 200 mg / kg of compound 16 (intravenous, tail vein) on days 1, 8, 15, 22, and 29. Rats were weighed periodically and blood was collected on days 10, 17, and 24. For in-life blood collection, rats were anesthetized with an inhalation mixture of 4% isoflurane and 1.5% oxygen, and then a volume of at least 1 mL of blood was collected by puncture of the retro-orbital plexus. On day 31, animals were weighed, blood was collected by cardiac puncture, and macroscopic findings were obtained to determine body composition. Clinical findings were unremarkable for albumin, albumin / globulin ratio, alkalinity, phosphatase, ALT (SGPT), AST (SGOT), bicarbonate, direct bilirubin, indirect bilirubin, total bilirubin, BUN, BUN / creatinine ratio, calcium, chloride, cholesterol, CK, creatinine, globulin, glucose, phosphorus, potassium, sodium, sodium / potassium ratio, and total protein, as compared to normal ranges and pre-dose data. Apart from weight loss and other findings reported herein, animals appeared generally normal and did not show any evidence of neurotoxicity, such as ataxia, disorientation, tremors, or convulsions. The results in Figure 7 show that compound 16 is tolerated at high doses on a q7d dosing schedule.
[0589] Working Example Male Sprague Dawley rats (N=3, average body weight 350 g) were administered a single intravenous bolus of either vehicle, Compound 1 (30 mg / kg), or Compound 16 (200 mg / kg). Blood samples were collected by saphenous vein puncture at 0, 0.25, 0.5, 1, 2, 4, 8, 24, and 48 hours later. Aliquots of each sample were diluted in methanol containing propranolol as an internal standard and analyzed by LC / MS / MS with a lower limit of quantification of 2.5 nM. The analyte in either Compound 1 or Compound 16 administration was Compound 1. The half-life of the small molecule Compound 1 was in the range of 10-15 minutes, with a maximum plasma concentration (Cmax) of approximately 15 μM and a T 0 For the polymer conjugate compound 16, the released small molecule exhibits a maximum plasma concentration of about 0.3 μM at about 3 hours and a terminal elimination half-life of 10 hours. These results are shown in FIG.
[0590] Example: In vivo study in DIO Levin rats - body weight change, food intake, body composition, schedule-dose response, leptin levels: A study was conducted to evaluate the relative efficacy of a fumagillol polymer conjugate, compound 16, and a small molecule fumagillol derivative, compound 1, and CKD-732 (also referred to as beloranib and ZGN-433). As used herein, CKD-732 has the following structure:
[0591] [ka]
[0592] The hemitartrate salt was also tested in the hemitartrate form.
[0593] Test articles were administered subcutaneously to a diet-induced obese (DIO) Levin-DS rat model on a q4d schedule. Compound 16 efficacy was also evaluated on a q7d dosing schedule. Dietary intervention (standard Chow, Labdiet 5001; 3.4 kcal / g) was included to compare with drug intervention. Male rats as young as 3 weeks of age were fed a Harlan diet TD.06414; 5.1 kcal / g pellets with 60% of calories from fat and 21% of calories from carbohydrate. Rats were randomized into groups of 3 animals with an average weight of 595 gm prior to dosing. Rats were treated with either phosphate buffered saline (vehicle), Compound 16 or Compound 1, or CKD-732 (dorsal, subcutaneous administration). Compound 16 was dissolved in the vehicle. Compound 1 in the hemitartrate form and CKD-732 in the hemitartrate form were dissolved in ethanol and then diluted with excipients. All doses were in a volume of 5.0 ml / kg. Treatment continued for 68 days at the doses and schedules shown in Table 10 below. Because the molecular weight of CKD-732 is 15% greater than that of Compound 1, CKD-732 was administered at 1.15 mg / kg, while Compound 1 was administered at 1 mg / kg for molar comparison purposes. At the first dose on Day 1, the rats were 14 weeks old. Also on Day 1, Group 2 was switched from a high-fat diet to a standard chow diet, while the other groups remained on a high-fat diet for the duration of the study.
[0594] [Table 12]
[0595] Animals were weighed every other day. Food intake was measured once a week. Blood samples were taken for evaluation of serum chemistry, including glucose and insulin, approximately once a week throughout the study. On day 48, all rats underwent a 4-hour fasting oral glucose tolerance test (OGTT). Animals were administered 8 mL / kg 25% glucose (2 g / kg) orally (per os, PO). On day 68, gross observations were obtained to determine body composition.
[0596] FIG. 11 shows the change in body weight versus test day for each group. Both Q4D and Q7D polymer conjugate groups showed a significant decrease in body weight. Treatment with compound 16 at 3 mg / kg (Q4D) or 6 mg / kg (Q7D) showed a greater weight loss than the change to standard chow. At the end of the study, compound 16 at 3 mg / kg on a Q4D schedule showed a body weight 22.1% lower than vehicle controls and 6.2% lower than rats on a standard chow diet. After about 10 weeks, treatment with compound 16 at 6 mg / kg on a Q7D schedule showed a body weight similar to treatment with a 3 mg / kg dose on a Q4D schedule. Compound 1 administered at 1 mg / kg on a Q4D schedule and CDK-732 administered at 1.15 mg / kg showed a body weight 3.9% or 3.2% lower than vehicle. Compound 1 administered at 3 mg / kg on a Q4D schedule showed a body weight 8.9% lower than vehicle. The polymer complex is approximately 1 / 6 the active fumagillol derivative by weight.
[0597] Figure 12 shows the final body weights on day 68 for all groups as a function of the average daily dose of fumagillol exposure. Both vehicle and standard diets had no fumagillol exposure. Compound 16 shows greater weight loss with significantly lower fumagillol exposure than Compound 1 or CKD-732 on the same schedule as this polymer conjugate. All groups were dosed on a Q4D schedule, except for Compound 16 at 6 mg / kg, which was dosed Q7D.

[0599] FIG. 13 shows the reduction in serum insulin levels in male Levin DIO rats maintained on a 60% fat diet and administered a compound of the invention on a q4d (3 mg / kg) and q7d (6 mg / kg) schedule compared to standard dietary intervention and vehicle groups.
[0600] [Table 14]
[0601] Table 12 shows the change in fasting insulin levels for each group. All groups (except the vehicle control group) showed a decrease in insulin levels, illustrating that the compounds of the present invention lower insulin levels on a less frequent dosing schedule.
[0602] Figure 14 shows the results of oral glucose tolerance test (OGTT) on insulin levels in rats treated with the compounds of the present invention on a q4d and q7d schedule, compared with standard diet intervention and vehicle group.Standard diet intervention also resulted in lower insulin levels.Compared to vehicle, insulin levels remain reduced in the presence of abnormally high glucose levels, indicating that lower levels of insulin are required to reduce blood glucose (see Figure 15), suggesting improved / restored insulin sensitivity.
[0603] FIG. 15 shows reduced glucose levels over time with different treatments following an oral glucose challenge.
[0604] [Table 15]
[0605] FIG. 16 shows the commonly accepted index of insulin sensitivity, glucose (mM / L)×insulin (uU / ml) / 22.5, in male Levin DIO rats (Matthews et al., Diabetologia (1985) 28, 412±419; Pickavance et al., British Journal of Pharmacology (1999) 128, 1570±1576).
[0606] [Table 16]
[0607] The adipocyte hormone leptin is a known appetite suppressant. Leptin resistance (abnormally high levels independent of food intake) is known to occur in patients and animals with diet-induced obesity (Levin et al., Am J Physiol Regul Integr Comp Physiol. 2002 Oct;283(4):R941-8). Low levels of leptin have been linked to hyperphagia (Sindelar et al., 1999, Enriori et al., 2006). Food intake was measured once a week. Serum leptin levels were measured on day 29 and plotted against food intake for the week including day 29. Animals on a standard chow diet were hyperphagic and showed significantly greater food intake relative to leptin levels than did the compounds of the invention. Treatment with Compound 1 did not result in a significant decrease in leptin levels. Figure 17 shows weekly food intake in grams for each group. The standard chow group showed a significant increase in food intake after switching from a high-fat diet to a standard diet. Binge eating is known to occur in order to maintain caloric intake.
[0608] [Table 17]
[0609] Figure 18 shows the change from baseline in leptin levels in male Levin DIO rats maintained on a high fat diet and treated with the complex of the present invention or standard chow intervention. A dose-dependent response was observed in the change from baseline in leptin levels for compound 16.
[0610] [Table 18]
[0611] Example: In vivo study of DIO mice - body weight change, food intake, schedule - dose response Male C57B1 / 6 mice (N=9 / group) aged 21 weeks with an average body weight of 46.8 g were fed a high-fat diet with 60% of calories from fat ad libitum. Animals were dosed according to the schedule in Table 17 below.
[0612] [Table 19]
[0613] Compound dosing occurred between 9-10 am on the day of dosing. Groups 6 and 7 received a total of 17 doses. q4d groups (1, 2, 3, 4, 8, 9) received a total of 9 doses. q8d group (5) received a total of 5 drug doses. Body weight and food intake were measured every other day. Blood glucose was measured in the fed state at 9:00 am on days -7, 0, 7, 14, 21, and 28 (blood glucose was measured before dosing on dosing days). Blood glucose was measured with a glucometer. An intraperitoneal glucose tolerance test (ipGTT, 6-hour fast) was performed.
[0614] The study was terminated on day 34. Liver and epididymal white adipose tissue (eWAT) were harvested, weighed, and stored at -80°C. Serum was collected and AST, ALT, ALP, CK, BUN, creatinine, calcium, potassium, sodium, chloride, total protein, albumin, total bilirubin, glucose, triglycerides, and cholesterol were determined. Insulin samples were measured using a commercially available kit.
[0615] The polymer referred to in this example is poly[HPMA-co-MA-GFLG-N-(6-aminohexyl)acetamide, a fumagillol-free polymer. The synthesis of poly[HPMA-co-MA-GFLG-N-(6-aminohexyl)acetamide is described in WO 2011 / 150022, which is incorporated herein by reference in its entirety.

[0618] Figure 19 shows the surprising and unexpected finding that the 12 mg / kg dose on a Q8D schedule results in greater initial weight loss than the 6 mg / kg dose on a Q4D schedule. By the end of the study, the Q8D group stopped losing weight, while the 6 mg / kg group appeared to continue losing weight. Polymers without fumagillol show similar weight changes to the vehicle.
[0619] Figure 20 shows that the small molecule CKD-732 (Compound B) administered on a Q2D (QOD) schedule responded better than the same average daily dose administered on a Q4D schedule. As expected, the small molecule responds better than more frequent dosing.
[0620] Figure 21 shows the reduction in food intake with compounds of the invention. Note the initial significant reduction in food intake in the 12 mg / kg group on a Q8D schedule, followed by recovery and then a cyclical reduction-recovery pattern.
[0621] Figure 22 shows significantly decreased insulin levels during ipGTT in male C57B16 mice maintained on a high fat diet. Compounds of the present invention significantly decreased the amount of insulin excreted by β-cells in the presence of hyperglycemia, indicating decreased resistance and improved insulin sensitivity. Note that fasting insulin was also decreased in all Compound 16 group mice.
[0622] FIG. 23 shows the change in total insulin AUC in male C57B16 mice maintained on a high fat diet during the glucose challenge as a function of treatment group.
[0623] FIG. 24 shows that blood glucose was reduced over the treatment period compared to the vehicle and polymer groups.
[0624] Figure 25 shows the product of glucose (mg / dl) and insulin (μU / ml) / 405 (Akagiri et al., A Mouse Model of Metabolic Syndrome, J. Clin. Biochem. Nutr., 42, 150-157, March 2008), i.e., the HOMA-ir measurement, which is a recognized measure of insulin resistance and a predictor of cardiovascular disease (Bonora et al., Diabetes Care. 2002, 25, 1135-1141).

[0626] Example Efficacy of various compounds in the DIO mouse model C57B16 male mice (N=6) were fed ad libitum with TD.06414, a high fat diet (Harlan diet) consisting of 60% of Kcal from fat. On the first day of the study, animals were randomly divided into groups such that the average weight of mice in each group was 47 g. Mice were treated with either phosphate buffered saline (vehicle) or a compound listed in Table 19 dissolved in vehicle (dorsal, subcutaneous administration). Treatment continued for 26 days at the doses and schedules shown in Table 19 below. The polymer referred to in this example is poly[HPMA-co-MA-GFLG-N-(6-aminohexyl)acetamide, a fumagillol-free polymer.
