Abstract
The present invention relates to a method of treatment of cachexia in a subject in need of treatment. More specifically, the present invention relates to the use of retinoid compounds that act on retinoid X receptors (RXRs) for the treatment of cachexia in a subject in need of treatment. The cachexia is associated with, in other words a complication of, a primary disease, condition or disorder. Primary diseases, conditions and disorders include, but are not limited to, cancer, AIDS, liver cirrhosis, diabetes mellitus, chronic renal failure, chronic obstructive pulmonary disease, chronic cardiac failure, immune system diseases (e.g., rheumatoid arthritis and systemic lupus erythematosus), tuberculosis, cystic fibrosis, gastrointestinal disorders (e.g., irritable bowel syndrome and inflammatory bowel disease), Parkinson's disease, anorexia nervosa, dementia, major depression, an aged condition and sarcopenia.

BACKGROUND OF THE INVENTION
Cachexia, which literally means 'bad condition', refers to involuntary weight loss, anorexia (loss of appetite), loss of protein and fat mass, gain in the proportion of body-water, and a variety of metabolic changes, which are associated with a primary disease, condition or disorder. Diseases, conditions or disorders which are typically associated with cachexia include, but axe not limited to, cancer, ATDS, liver cirrhosis, diabetes mellitus, chronic renal failure, chronic obstructive pulmonary disease, chronic cardiac failure, immune system diseases (e.g., rheumatoid arthritis and systemic lupus erythematosus), tuberculosis, cystic fibrosis, gastrointestinal disorders (e.g., irritable bowel syndrome and inflammatory bowel disease), Parkinson's disease, dementia, anorexia nervosa, major depression, an aged condition and sarcopenia. Cachexia is a strong independent risk factor for morbidity and mortality. Cancer cachexia occurs in about half of all cancer patients.
The fact that a large proportion of cancer patients have cachexia, coupled with the demonstrated relationship between cachexia and mortality has provided impetus for the search into underlying mechanisms and therapies that might prevent or reverse cachexia. However, this need has gone largely unmet.
SUMMARY OF THE INVENTION
The present invention relates to a method of treating of cachexia in a subject in need of treatment. More specifically, the present invention relates to the use of retinoid compounds that act on retinoid X receptors (RXRs) for the treating of cachexia in a subject in need of treatment. The cachexia is associated with, in other words a complication of, a primary disease, condition or disorder. Primary diseases, conditions and disorders include, but are not limited to, cancer, AIDS, liver cirrhosis, diabetes mellitus, chronic renal failure, chronic obstructive pulmonary disease, chronic cardiac failure, immune system diseases (e.g., rheumatoid arthritis and systemic lupus erythematosus), tuberculosis, cystic fibrosis, gastrointestinal disorders (e.g., irritable bowel syndrome and inflammatory bowel disease), Parkinson's disease, dementia, major depression, anorexia nervosa, an aged condition and sarcopenia. In one embodiment, the cachexia is associated with one or more of AIDS, liver cirrhosis, diabetes mellitus, chronic renal failure, chronic obstructive pulmonary disease, chronic cardiac failure, immune system diseases, tuberculosis, cystic fibrosis, gastrointestinal disorders, an aged condition and sarcopenia.

DETAILED DESCRIPTION OF THE INVENTION
CACHEXIA
Cachexia, which literally means 'bad condition', refers to involuntary weight loss, anorexia (loss of appetite), loss of protein and fat mass, gain in the proportion of body-water, and a variety of metabolic changes, which are associated with a primary disease, condition or disorder. The metabolic changes that can occur with cachexia include, for example, an elevation of resting energy expenditures (REEs) (Ann. Surg., 19~: 152 (1983)), glucose intolerance and insulin resistance (Cancer Res., 44: 1718 (1984)), an increase in fat oxidation rates (Metabolism, 35:
15. (1986)) and whole body protein turnover (Cancer Res., 82: 42 (1998)). The pattern of weight loss in cachexia is different from normal starvation. For example, the normal adaptive response to nutrient deprivation is to draw on energy-dense lipid while sparing protein, resulting in loss of fat and relative preservation of lean body mass. In contrast, cachectic patients experience severe and incapacitating muscle wasting with relative sparing of adipose tissue.
Disease, conditions or disorders that are typically associated with cachexia include, but are not limited to, cancer, AIDS, liver cirrhosis, diabetes mellitus, chronic renal failure, chronic obstructive pulmonary disease, chronic cardiac failure, immune system diseases (e.g., rheumatoid arthritis and systemic lupus erythematosus), tuberculosis, cystic fibrosis, gastrointestinal disorders (e.g., irntable bowel syndrome and inflammatory bowel disease), Parkinson's disease, dementia, major depression, anorexia nervosa, an aged condition and sarcopenia. More typically, the disease, conditions or disorders that are associated with cachexia include, but are not limited to, cancer, AIDS, liver cirrhosis, chronic renal failure, chronic obstructive pulmonary disease, chronic caxdiac failure, immune system diseases (e.g., rheumatoid arthritis and systemic lupus erythematosus), tuberculosis, cystic fibrosis, gastrointestinal disorders (e.g., irntable bowel syndrome and inflammatory bowel disease), Parkinson's disease, dementia, major depression, anorexia nervosa, an aged condition and sarcopenia. Cachexia is a strong independent risk factor for morbidity and mortality. For example, cancer cachexia occurs in about half of all cancer patients and is more common in patients with lung and upper gastronintestinal cancers (for a more detailed description see the publications: Natur a Reviews Cancer, 2: 862 (2002); Proc. Natl. Acad. Sci.
USA, 100: 5384 (2003); CA Cancer J. Clin., 52: 72 (2002)). Cancer patients with an involuntary 5% weight loss have a shorter median survival rate than patients with stable weight. Cancer patients with weight loss can respond poorly to chemotherapy and also can require increased chemotherapy treatments (Afn. J. Med., 69: 491 (1980)). The fact that a large proportion of cancer patients have cachexia, coupled with the demonstrated relationship between cachexia and mortality, has provided impetus for the search into underlying mechanisms and therapies that might prevent or reverse cachexia and provide a model for identifying additional therapies.
Studies indicate that deregulation of neuroendocrine hormones, particularly catecholamines, glucagon, corticosterone, leptin and growth hormone are involved in the induction of cachexia (for reviews see Int. J. Cardiol., 85: 111 (2002); J.
Nutriti~n, 129: 2905 (1999)). More importantly, inappropriate production and release of cytokines such as TNF-a, interleukin-1, interleukin-6, interferon-~y, leukemia inhibitory factor, and ciliary neurotrophic factor, either alone or in combination, are able to cause the metabolic changes associated with cachexia and finally to induce wasting (for reviews see Drug Discov. Today, 8: 838 (2003);
Izzt. J.
Cardiol., 85: 73 (2002)). Decent studies indicate that the ubiquitin-proteasome proteolytic pathway plays a role in wasting of skeletal muscle and the intracellular events and transcription factors are also involved (Nature-Review-Cancer, 2:862-871 (2002)).
A variety of strategies have been tried to achieve these aims, which include ( 1 ) use of nutritional supplementation with improved diet, (2) administration of agents that can reduce energy expenditures, e.g., (3-adrenergic blockers and nonsteroidal anti-inflammatory drugs such as COX inhibitors, (3) appetite stimulants, e.g., progesterone and cannabinoids, (4) anabolic stimulants, e.g., testosterone and IGF-1, (5) anticytokines, e.g., ,Q-2 agonist such as clenbuterol and analogues, omega-3 fatty acids, melatonin, and thalidomide, and (5) miscellaneous agents, e.g., Ghrelin, anadamide, ponalrestat, ATP, cyclic plasma perfusion, receptor agonist A, IL-15 and decoy nuclear factor KB (Current Ofxcology Reports, 4:264-274 (2002)). There are currently four approved drug products for the treatment of wasting and some of them are used for AIDS-related cachexia:
Oxandrolone, Dronabinol, Megestrol acetate and growth hormone. (for a review, see J. Nutrition, 129: 3035 (1999)).
Oxandrolone is an anabolic steroid being a synthetic derivative of testosterone. The indications for Oxandrolone include use as an adjunctive therapy to promote weight gain following weight loss after extensive surgery, chronic infections, or severe trauma; for patients with unexplained weight loss; and to offset protein catabolism associated with prolonged corticosteroid use. Dronabinol is an orally active cannabinoid first approved for the treatment of nausea and vomiting and were extended in 1992 to the treatment of anorexia associated with AIDS.
The third drug approved for a wasting related indication was megestrol acetate, a synthetic progesterone derivative. It is approved for the treatment of anorexia, cachexia or weight loss in patients with AIDS and hormone-sensitive malignancies.
Growth hormone has been approved for the treatment of ASS wasting and cachexia. This drug received accelerated approval for wasting based on a positive change in lean body mass.
Despite of the numerous efforts in developing treatments for cachexia, few efficacious therapeutic solutions are known. In randomized clinical trials, dietary counseling and use of nutritional supplements have failed to ameliorate the symptoms of cachexia in chronically ill, nonmalignant patients (for reviews, see elm.
.I. Glin. Nutr., 74: 6 (2001); .I. Nutriti~h, 129: 5290 (1999)). Furthermore, artificial and aggressive feeding does not appear to have an impact on the overall survival of advanced cancer patients (J. Glin. Oncol., 2: 534 (1984)) and the global quality of life remains unaffected. Drugs that enhance appetite and anabolic therapies, despite the demonstrated efficacy in randomized clinical trials, do not have a major long-term impact on the vast majority of patients. For example, Dronabinol treatment was associated with improved appetite but had no effect on mood and body weight improvement (.I. Clin. OrZCOI., 20: 567 (2002)). On the other hand, Oxandrolone _27_ treatment resulted in a moderate increase of body weight that might have represented primary edema (Proc. Ana. Soc. Clira. Oncol., 21: 363a (2002)).
Megestrol acetate treatment resulted in body weight gain of at least five pounds in AIDS as well as cancer patients (AIDSRes. Hurn. Retrov., 13: 305 (1997); J.
Clira.
Oncol., 11: 762 (1993); Annals Oncol., 12: 289 (2001)). However, the primary body component that increased was fat, but not lean body mass.
Therefore, taken together, it is difficult to determine the actual clinical relevance, e.g., impact on morbidity, mortality, or quality of life, of the pharmacological therapies in cachectic patients. As such, there is a need for improved methods for the treatment of cachexia. In a preferred embodiment of the invention, the cachexia being treated is associated with one or more diseases, conditions and disorders selected from the group consisting of cancer, AIDS, liver cirrhosis, diabetes mellitus, chronic renal failure, chronic obstructive pulmonary disease, chronic cardiac failure, immune system diseases, tuberculosis, cystic fibrosis, gastrointestinal disorders, an aged condition and sarcopenia. In one particularly preferred embodiment, the cachexia is associated with one or more of AIDS, liver cirrhosis, diabetes mellitus, chronic renal failure, chronic obstructive pulmonary disease, chronic cardiac failure, immune system diseases, tuberculosis, cystic fibrosis, gastrointestinal disorders, an aged condition and sarcopenia.
In another particularly preferred embodiment, the cachexia is associated with one or more of cancer, AIDS, liver cirrhosis, chronic renal failure, chronic obstructive pulmonary disease, chronic cardiac failure, immune system diseases, tuberculosis, cystic fibrosis, gastrointestinal disorders, an aged condition and sarcopenia.
In yet another preferred embodiment, the cachexia is associated with one or more of ASS, liver cirrhosis, chronic renal failure, chronic obstructive pulmonary disease, chronic cardiac failure, immune system diseases, tuberculosis, cystic fibrosis, gastrointestinal disorders, an aged condition and sarcopenia. In a specific embodiment, the cachexia is associated with cancer. In another specific embodiment, the cachexia is associated with AIDS.
_28_ CANCER

For example, cancers include, but are not limited to, leukemias and lymphomas such as cutaneous T-cell lymphoma (CTCL), non-cutaneous peripheral T-cell lymphoma, lymphomas associated with human T-cell lymphotropic virus (HTLV), for example, adult T-cell leukemia/lyrnphoma (ATLL), acute lymphocytic leukemia, acute nonlymphocytic leukemias, chronic lymphocytic leukemia, chronic myelogenous leukemia, Hodgkin's Disease, non-Hodgkin's lymphomas, and multiple myeloma, childhood solid tumors such as brain tumors, neuroblastoma, retinoblastoma, Wilms' Tumor, bone tumors, and soft-tissue sarcomas, common solid tumors of adults such as head and neck cancers (e.g., oral, laryngeal and esophageal), genitourinary cancers (e.g., prostate, bladder, renal, uterine, ovarian, testicular, rectal and colon), lung cancer, breast cancer, pancreatic cancer, melanoma and other skin cancers, stomach cancer, brain tumors, liver cancer, biliary cancer, gastrointestinal cancers (e.g., small intestinal, gastric) and thyroid cancer.
RETIN~~ X RECEFT~R (RXR) AG~NISTS
There are two main types of retinoid receptors that have been identified in mammals (and other organisms). The two main types or families of receptors are respectively designated the Retinoid Acid Receptors (R.ARs) and Retinoid X
Receptors (RXRs).
The Retinoid X Receptor (RXR) is a member of the nuclear hormone receptor family of proteins. RXR contains two signature domains of nuclear receptor family proteins, the DNA-binding domain and ligand binding domain (LBD). RJR
is a ligand-dependent transcription factor. The endogenous ligand for RXR is 9-cis retinoic acid. RXR plays an important role in many fundamental biological processes such as reproduction, cellular differentiation, bone development, hematopoiesis and pattern formation during embryogenesis (Mangelsdorf, D.J. et al., Cell, 83: 841-850 (1995)). RXR is also implicated in some pathological conditions as neoplastic formation and it is a potential target for cancer therapy (Nagy, L., et al., Cell Death and Diff., 5: 11-19 (1998)).
The mammalian RXR includes at least three distinct genes, RXR~, RXR~ and RXRy (RXR alpha, beta and gamma) which give rise to a large number of protein products through differential promoter usage and alternative splicing.
Compounds useful in treating cachexia can be agonists for the RXR~, RXR~ or RXRy receptor.
Besides acting as a homodimer, RXR plays a central role in regulating the activity of other nuclear hormone receptors by acting as a partner for heterodimers. RXR
forms a functional heterodimer with retinoic acid receptor (RAR), thyroid hormone receptor, vitamin D receptor, NGFI-B and many other nuclear receptors. The different binding partners of the RXR render a different DNA-binding specificity of the heterodimer.
As used herein, RXR refers to naturally occurring RXRs (e.g., mammalian RXRs (e.g., human (Homo sapien) RXRs, marine (e.g., rat, mouse) RXRs) and to proteins having an amino acid sequence which is the same as that of a corresponding naturally occurring RXR (e.g., recombinant proteins). The term includes naturally , occurring variants, such as polymorphic or allelic variants and splice variants.
As used herein, the term an RXR agonist refers to a substance (e.g., a molecule; a compound) which promotes (induces or enhances) at least one function characteristic of an RXR. In one embodiment, the R~~R agonist binds the RJR.
In certain embodiments, the agonist is a partial agonist. Partial agonist, as used herein, refers to an agonist which no matter how high of a concentration is used, is unable to produce maximal activation of the RXR. Some RXR agonists may have mixed agonist-antagonist activity.
An PAR agonist can be identified and activity assessed by any suitable method. For example a ehimeric receptor transactivation assay that tests for agonist-like activity in the RARE, R.AR~, RARy, P~R« receptor subtypes, and that is based on work published by Feigner P. L. and Holm M. Focus, 112, (1989), is described in detail in United States Patent No. 5,455,265, which is hereby incorporated by reference. In addition, a holoreceptor transactivation assay and a ligand binding assay that measure the antagonist/agonist like activity of the compounds of the invention, or their ability to bind to the several retinoid receptor subtypes, respectively, are described in WO 93/11755 (particularly on pages 30-and 37-41) published on June 24, 1993, the content ofwhich is also incorporated herein by reference. A detailed experimental procedure for holoreceptor transactivations has been described by Heyman et al., Cell 68: 397-406, (1992);
Allegretto et al., J. Biol. Chem, 268: 26625-26633, and Mangelsdorf et al., The Retinoids: Biology, Chemistry and Medicine, pp 319-349, Raven Press Ltd., New York, which are incorporated herein by reference. The results obtained in this assay and the chimeric receptor transactivation assay, are expressed as ECso values.
Still another transactivation assay, the "PGR assay" is described in Klein et al., J. Biol.

TREATMENT
Me Me Treating, as used herein, refers to a reduction in (alleviation of) at least one symptom ~of cachexia in a patient suffering from (in need of treatment for) cachexia.
Treating, as used herein, also refers to preventing the onset of at least one symptom of cachexia in a subject at risk of developing cachexia (e.g., a subject suffering from one or more of the diseases, disorders or conditions named above). Treating, as used herein, further refers to inhibiting the progression of at least one symptom of cachexia in a subject. Preferably, as with any multisymptom disorder, a reduction in or inhibition or prevention of more than one symptom is desired. The symptoms of cachexia can include loss of appetite, loss of body weight, elevation of resting energy expenditures, glucose intolerance, insulin resistance, increased fat oxidation rates, increased whole body protein turnover, decreased quality of life (e.g., decreased mobility, energy andlor stamina) and decreased life span. As such, treating of cachexia can include prevention or inhibition of appetite loss or return of appetite, prevention or inhibition of loss of body weight or an increase in body weight (e.g., as a result of preservation or restoration of lean body mass and the energy store of fat and glycogen), improvement in the patients quality of life and increased life span.
Quality of Life can be assessed by objective measurements which include nutritional and metabolic endpoints, physical function (muscle strength) and endurance (exercise tolerance). Quality of Life can also be evaluated by completing patient and caregiver questionnaires, which include standard forms such as the functional living index-cancer (FLIC), functional assessment of cancer therapy index (FACT) and the European Organization for Research and Treatment of Cancer (RORTC). The questionnaires are designed to give information regarding the effect of the drug product from a patient's and caregiver's perspective.
For the prevention or treatment of cachexia (e.g., cachexia resulting from a cancerous condition or other malignancies) it is likely that a compound of the invention is to be administered systemically. Suitable routes of administration include, but are not limited to, orally, intraperitoneally, subcutaneously, intramuscularly, intradermally, transdermally, rectally, sublingually, intravenously, buccally or via inhalation. For intravenous or intraperitoneal administration, the compound will be prepared as a solution or suspension capable of being administered by injection. In certain cases, it may be useful to formulate these compounds in suppository form or as extended release formulation for deposit under the skin or intramuscular injection. Oral admininistration of a compound in accordance with the present invention is presently preferred.
Forms suitable for oral administration include powders, pills, tablets, troches, capsules, elixirs, suspensions, syrups, wafers, chewing gum or the like prepared by art recognized procedures. The amount of active compound in such therapeutically useful compositions or preparations is such that a suitable dosage will be obtained.
The pharmaceutical compositions of the invention preferably contain a pharmaceutically acceptable carnet or diluent suitable for rendering the compound or mixture administrable orally, parenterally, intravenously, intradermally, intramuscularly or subcutaneously, rectally, via inhalation or via buccal administration, or transdermally. The active ingredients may be admixed or compounded with a conventional, pharmaceutically acceptable carrier or diluent. It will be understood by those skilled in the art that any mode of administration, vehicle or carnet conventionally employed and which is inert with respect to the active agent may be utilized for preparing and administering the pharmaceutical compositions of the present invention. Illustrative of such methods, vehicles and carriers are those described, for~example, in Remington's Pharmaceutical Sciences, 18th ed.
(1990), the disclosure of which is incorporated herein by reference.
The formulations of the present invention for use in a subject comprise the agent, together with one or more acceptable carriers or diluents therefor and optionally other therapeutic ingredients. The Garners or diluents must be "acceptable"
in the sense of being compatible with the other ingredients of the formulation and not deleterious to the recipient thereof. The formulations can conveniently be presented in unit dosage form and can be prepared by any of the methods well known in the art of pharmacy. All methods include the step of bringing into association the agent with the carrier or diluent which constitutes one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association the agent with the carriers and then, if necessary, dividing the product into unit dosages thereof.
Formulations suitable for parenteral administration conveniently comprise sterile aqueous preparations of the agents that are preferably isotonic with the blood of the recipient. Suitable Garner solutions include phosphate buffered saline, saline, water, lactated ringers or dextrose (5% in water). Such formulations can be conveniently prepared by admixing the agent with water to produce a solution or suspension, which is filled into a sterile container and sealed against bacterial contamination. Preferably, sterile materials are used under aseptic manufacturing conditions to avoid the need for terminal sterilization.
Such formulations can optionally contain one or more additional ingredients, which can include preservatives such as methyl hydroxybenzoate, chlorocresol, metacresol, phenol and benzalkonium chloride. Such materials are of special value when the formulations are presented in multidose containers.
Buffers can also be included to provide a suitable pH value for the formulation. Suitable buffer materials include sodium phosphate and acetate.
Sodium chloride or glycerin can be used to render a formulation isotonic with the blood.
If desired, a formulation can be filled into containers under an inert atmosphere such as nitrogen and can be conveniently presented in unit dose or multi-dose form, for example, in a sealed ampoule.
Those skilled in the art will be aware that the amounts of the various components of the compositions of the invention to be administered in accordance with the method of the invention to a subject will depend upon those factors noted above.
The compositions of the invention when given orally or via buccal administration can be formulated as syrups, tablets, capsules and lozenges. A
syrup formulation will generally consist of a suspension or solution of the compound or salt in a liquid carrier, for example, ethanol, glycerine or water, with a flavoring or coloring agent. Where the composition is in the form of a tablet, one or more pharmaceutical carriers routinely used for preparing solid formulations can be employed. Examples of such Garners include magnesium stearate, starch, lactose and sucrose. Where the composition is in the form of a capsule, the use of routine encapsulation is generally suitable, for example, using the aforementioned carriers in a hard gelatin capsule shell. Where the composition is in the form of a soft gelatin shell capsule, pharmaceutical carriers routinely used for preparing dispersions or suspensions can be considered, for example, aqueous gums, celluloses, silicates or oils, and are incorporated in a soft gelatin capsule shell.
A typical suppository formulation includes the conjugate or a pharmaceutically acceptable salt thereof which is active when administered in this way, with a binding and/or lubricating agent, for example, polymeric glycols, gelatins, cocoa-butter or other low melting vegetable waxes or fats.
Typical transdermal formulations include a conventional aqueous or non-aqueous vehicle, for example, a cream, ointment, lotion or paste or are in the form of a medicated plastic, patch or membrane.
Typical compositions for inhalation are in the form of a solution, suspension or emulsion that can be administered in the form of an aerosol using a conventional propellant such as dichlorodifluoromethane or trichlorofluoromethane.
A "subject" is typically a human, but can also be an animal in need of treatment, e.g., companion animals (e.g., dogs, cats, and the like), farm animals (e.g., cows, pigs, horses, sheep, goats and the like) and laboratory animals (e.g., rats, mice, guinea pigs and the like).
The therapeutically effective amount of a compound of the invention depends, in each case, upon several factors, e.g., the health, age, gender, size and condition of the subject to be treated, the intended mode of achninistration, and the capacity of the subject to incorporate the intended dosage form, among others.
A
therapeutically effective amount of an active agent is an amount sufficient to have the desired effect for the condition being treated. Desired treatment effects are discussed in detail above. A useful therapeutic or prophylactic concentration may vary with the severity of the condition being treated and the patient's susceptibility to treatment. Accordingly, no single concentration will be uniformly useful, but will require modification depending on the particularities of the disease being treated.
Such concentrations can be arrived at through routine experimentation.
A suitable dose for mammals (e.g., humans or mammals other than humans) can range from about 0.01 to about 100 mg per kg of body weight per day, such as from about 0.1 to about 75 mg per kg of body weight per day, for example, from about 1 to about 50 mg per kg of body weight per day. More preferably, the daily dose can be from about 2 to about 25 mg per kg body weight of the mammal. In a preferred embodiment, the subj ect is a human and a suitable dose is about 10 to about 4000 mg per day per subj ect, such as about 20 to about 2000 mg per day per subject, for example, about 50 to about 1000 mg per day per subject, assuming an average human of about 70 kg. More preferably, a suitable amount is in the range from about 100 to about 500 mg per day per subject.
The method of the invention can further comprise administering an additional therapeutic agent. Preferably, the additional therapeutic agent does not diminish the effects of the primary agents) and/or potentiates the effect of the primary agent(s).
In one embodiment, the additional therapeutic agent can be one that is useful for treating cachexia. For example, the additional therapeutic agent can be an anticachetic agent that has a primary mechanism of action which is different from the RXR agonists described herein. Suitable anticachetic agents include, but are not limited to, progesterone derivatives (e.g., megestrol acetate and medroxyprogesterone acetate), growth hormone (e.g,. Serostim~), growth hormone secretagogues (e.g., ghrelin, GHRP-1, GHRP-2, GHRP-6, NN703, Ipamorelin, Campromorelin, MIA-677 and those described in U.S. Patent Nos. 6,303,620, 6,576,648, 5,977,178, 6,566,337, 6,083,908, 6,274,584 and published International Application No. WO 00/01726), cannabinoids (e.g., dronabinol), anabolic steroids (e.g., oxandrolone), corticosteroids (e.g., dexamethasone), monoclonal antibodies (e.g., entanercept (ENBREL~ and REMICADE~)), ~3-Adrenergic blockers, NSAIDS, anticytokines (e.g., ,Q-2 agonist such as clenbuterol, omega-3 fatty acids, melatonin and thalidomide), metoclopramide, insulin-like growth factor-1 (see WO
96/37216), tumor necrosis factor converting enzyme inhibitors, matrix metalloproteinase inhibitors (see WO 03/090777), appetite stimulants, melanocortin receptors, serotonin receptor inhibitors and hydrazine sulfate.

A pharmaceutically acceptable salt may be prepared for any compounds in this invention having a functionality capable of forming such salt, for example an acid functionality. A pharmaceutically acceptable salt is any salt which retains the activity of the parent compound and does not impart any deleterious or untoward effect on the subj ect to which it is administered and in the context in which it is administered. Pharmaceutically acceptable salts may be derived from organic or inorganic bases. The salt may be a mono or polyvalent ion. Of particular interest are the inorganic ions, sodium, potassium, calcium, and magnesium. Organic salts may by be made with amines, particularly ammonium salts such as mono-, di- and trialkyl amines or ethanol amines. Salts may also be formed with caffeine, tromethamine and similar molecules. Where there is a nitrogen sufficiently basic as to be capable of forming acid addition salts, such may be formed with any inorganic or organic acids or alkylating agent such as methyl iodide. Preferred salts are those formed with inorganic acids such as hydrochloric acid, sulfuric acid or phosphoric acid. Any of a number of simple organic acids such as mono-, di- or tri- acid may also be used.
Certain compounds of the present invention have traps and cis (E and Z) isomers. In addition, the compounds of the present invention may contain one or more chiral centers and therefore may exist in enantiomeric and diastereomeric forms. The scope of the present invention is intended to cover all such isomers. per se, as well as mixtures of cis and traps isomers, mixtures of diastereomers and racemic mixtures of enantiomers (optical isomers) as well. In the present application when no specific mention is made of the configuration (cis, traps or R or S) of a compound (or of an asymmetric carbon) then a mixture of such isomers, or either one of the isomers is intended. In a similar vein, when in the chemical structural formulas of this application a straight line representing a valence bond is drawn to an asymmetric carbon, then isomers of both R and S configuration, as well as their mixtures are intended. A straight horizontal single line or a wavy single line drawn to a carbon with a double bond denotes either cis or traps or both orientations of the substituent on the double_bond. Specific orientation of substituents relative to a double bond is indicated in the name of the respective compound, and/or by specifically showing in the structural formula the orientation of the substituents relative to the double bond.
EXEMPLIFICATION
FIGS. 1-5 comprise charts or graphs disclosing the results of tests obtained with experimental animals that have been inoculated with a xenograft of non-small cell lung cancer cells H292 or with small cell lung cancer cells H446, and which were then orally administered the RXR agonist Compound 1 referred to above.
FIGS. 6 and 7 disclose results of tests obtained with experimental animals that have been inoculated with a xenograft of non-small cell lung cancer cells and which were then orally administered the RXR agonist Compound 2 referred to above.
Specifically, in the experiment shown in FIG. 1 nude mice were subcutaneously transplanted with non-small cell lung cancer cells H292. A
group of the animals was given a daily oral dose of 10 mg per kilogram body weight of Compound 1 in a suitable pharmaceutically acceptable vehicle. A group of the control animals was given the vehicle only. The graph shows the body weight of the animals in grams. It can be seen that the animals treated with Compound 1 have significantly greater body weights than the animals which received the vehicle only.
FIG. 2 shows the percentage of survival of nude mice from a similar experiment as the one described in connection with FIG. 1, and demonstrates significantly better survival rate for the animals that received Compound 1 in a daily oral dose of 10 mg per kg body weight of the animal.
In the experiment shown in FIG. 3, SLID mice were subcutaneously transplanted with small cell lung cancer cells H446. A first group of the animals was given a daily oral dose of 3 mg per kilogram body weight of Compound 1 in a suitable pharmaceutically acceptable vehicle, and a second group was given a daily oral dose of 10 mg per kilogram body,weight in the same vehicle. A group of the control animals was given the vehicle only. The graph shows the body weight of the animals in grams. It can be seen that the animals treated with Compound 1 have significantly greater body weights than the animals that received the vehicle only.
In the experiment shown in FIG. 4 the right gastrocnemius muscle of the control animals and of the animals treated with Compound 1 in a daily dose of mg/kg, as described in connection with FIG. 1, was weighed after the animals had been sacrificed. It can be seen that treatment in accordance with the invention prevents muscle wasting.
In the experiment shown in FIG. 5, the food intake of nude mice with and without H292 xenografts was evaluated. Mice with H292 xenografts had reduced appetite compared with normal control. Mice treated with Compound 1 in a daily dose of 10 mg/kg body weight had equal amount of food intake as normal mice.
Therefore, adminstration of Compound 1 reverses poor appetite in cachectic animals.
In the experiment shown in FIG. 6, nude mice were subcutaneously transplanted with non-small cell lung cancer cells H292. A group of the animals was given a daily oral dose of 50 mg per kilogram body weight of Compound 2 in a suitable pharmaceutically acceptable vehicle. A group of the control animals was given the vehicle only. The graph shows the body weight of the animals in grams. It can be seen that the animals treated with Compound 2 have significantly greater body weights than the animals which received the vehicle only.
In the experiment shown in FIG. 7, the food intake of nude mice bearing H292 xenografts was evaluated. Mice treated with Compound 2 in a daily dose of mg/kg body weight had significantly larger food intake than the tumor bearing mice which received only vehicle. Therefore, adminstration of Compound 2 significantly increases the appetite of tumor bearing animals.

DETAILED DESCRIPTION OF THE INVENTION
CACHEXIA
Cachexia, which literally means 'bad condition', refers to involuntary weight loss, anorexia (loss of appetite), loss of protein and fat mass, gain in the proportion of body-water, and a variety of metabolic changes, which are associated with a primary disease, condition or disorder. The metabolic changes that can occur with cachexia include, for example, an elevation of resting energy expenditures (REEs) (Ann. Surg., 19~: 152 (1983)), glucose intolerance and insulin resistance (Cancer Res., 44: 1718 (1984)), an increase in fat oxidation rates (Metabolism, 35:
15. (1986)) and whole body protein turnover (Cancer Res., 82: 42 (1998)). The pattern of weight loss in cachexia is different from normal starvation. For example, the normal adaptive response to nutrient deprivation is to draw on energy-dense lipid while sparing protein, resulting in loss of fat and relative preservation of lean body mass. In contrast, cachectic patients experience severe and incapacitating muscle wasting with relative sparing of adipose tissue.
Disease, conditions or disorders that are typically associated with cachexia include, but are not limited to, cancer, AIDS, liver cirrhosis, diabetes mellitus, chronic renal failure, chronic obstructive pulmonary disease, chronic cardiac failure, immune system diseases (e.g., rheumatoid arthritis and systemic lupus erythematosus), tuberculosis, cystic fibrosis, gastrointestinal disorders (e.g., irntable bowel syndrome and inflammatory bowel disease), Parkinson's disease, dementia, major depression, anorexia nervosa, an aged condition and sarcopenia. More typically, the disease, conditions or disorders that are associated with cachexia include, but are not limited to, cancer, AIDS, liver cirrhosis, chronic renal failure, chronic obstructive pulmonary disease, chronic caxdiac failure, immune system diseases (e.g., rheumatoid arthritis and systemic lupus erythematosus), tuberculosis, cystic fibrosis, gastrointestinal disorders (e.g., irntable bowel syndrome and inflammatory bowel disease), Parkinson's disease, dementia, major depression, anorexia nervosa, an aged condition and sarcopenia. Cachexia is a strong independent risk factor for morbidity and mortality. For example, cancer cachexia occurs in about half of all cancer patients and is more common in patients with lung and upper gastronintestinal cancers (for a more detailed description see the publications: Natur a Reviews Cancer, 2: 862 (2002); Proc. Natl. Acad. Sci.
USA, 100: 5384 (2003); CA Cancer J. Clin., 52: 72 (2002)). Cancer patients with an involuntary 5% weight loss have a shorter median survival rate than patients with stable weight. Cancer patients with weight loss can respond poorly to chemotherapy and also can require increased chemotherapy treatments (Afn. J. Med., 69: 491 (1980)). The fact that a large proportion of cancer patients have cachexia, coupled with the demonstrated relationship between cachexia and mortality, has provided impetus for the search into underlying mechanisms and therapies that might prevent or reverse cachexia and provide a model for identifying additional therapies.
Studies indicate that deregulation of neuroendocrine hormones, particularly catecholamines, glucagon, corticosterone, leptin and growth hormone are involved in the induction of cachexia (for reviews see Int. J. Cardiol., 85: 111 (2002); J.
Nutriti~n, 129: 2905 (1999)). More importantly, inappropriate production and release of cytokines such as TNF-a, interleukin-1, interleukin-6, interferon-~y, leukemia inhibitory factor, and ciliary neurotrophic factor, either alone or in combination, are able to cause the metabolic changes associated with cachexia and finally to induce wasting (for reviews see Drug Discov. Today, 8: 838 (2003);
Izzt. J.
Cardiol., 85: 73 (2002)). Decent studies indicate that the ubiquitin-proteasome proteolytic pathway plays a role in wasting of skeletal muscle and the intracellular events and transcription factors are also involved (Nature-Review-Cancer, 2:862-871 (2002)).
A variety of strategies have been tried to achieve these aims, which include ( 1 ) use of nutritional supplementation with improved diet, (2) administration of agents that can reduce energy expenditures, e.g., (3-adrenergic blockers and nonsteroidal anti-inflammatory drugs such as COX inhibitors, (3) appetite stimulants, e.g., progesterone and cannabinoids, (4) anabolic stimulants, e.g., testosterone and IGF-1, (5) anticytokines, e.g., ,Q-2 agonist such as clenbuterol and analogues, omega-3 fatty acids, melatonin, and thalidomide, and (5) miscellaneous agents, e.g., Ghrelin, anadamide, ponalrestat, ATP, cyclic plasma perfusion, receptor agonist A, IL-15 and decoy nuclear factor KB (Current Ofxcology Reports, 4:264-274 (2002)). There are currently four approved drug products for the treatment of wasting and some of them are used for AIDS-related cachexia:
Oxandrolone, Dronabinol, Megestrol acetate and growth hormone. (for a review, see J. Nutrition, 129: 3035 (1999)).
Oxandrolone is an anabolic steroid being a synthetic derivative of testosterone. The indications for Oxandrolone include use as an adjunctive therapy to promote weight gain following weight loss after extensive surgery, chronic infections, or severe trauma; for patients with unexplained weight loss; and to offset protein catabolism associated with prolonged corticosteroid use. Dronabinol is an orally active cannabinoid first approved for the treatment of nausea and vomiting and were extended in 1992 to the treatment of anorexia associated with AIDS.
The third drug approved for a wasting related indication was megestrol acetate, a synthetic progesterone derivative. It is approved for the treatment of anorexia, cachexia or weight loss in patients with AIDS and hormone-sensitive malignancies.
Growth hormone has been approved for the treatment of ASS wasting and cachexia. This drug received accelerated approval for wasting based on a positive change in lean body mass.
Despite of the numerous efforts in developing treatments for cachexia, few efficacious therapeutic solutions are known. In randomized clinical trials, dietary counseling and use of nutritional supplements have failed to ameliorate the symptoms of cachexia in chronically ill, nonmalignant patients (for reviews, see elm.
.I. Glin. Nutr., 74: 6 (2001); .I. Nutriti~h, 129: 5290 (1999)). Furthermore, artificial and aggressive feeding does not appear to have an impact on the overall survival of advanced cancer patients (J. Glin. Oncol., 2: 534 (1984)) and the global quality of life remains unaffected. Drugs that enhance appetite and anabolic therapies, despite the demonstrated efficacy in randomized clinical trials, do not have a major long-term impact on the vast majority of patients. For example, Dronabinol treatment was associated with improved appetite but had no effect on mood and body weight improvement (.I. Clin. OrZCOI., 20: 567 (2002)). On the other hand, Oxandrolone _27_ treatment resulted in a moderate increase of body weight that might have represented primary edema (Proc. Ana. Soc. Clira. Oncol., 21: 363a (2002)).
Megestrol acetate treatment resulted in body weight gain of at least five pounds in AIDS as well as cancer patients (AIDSRes. Hurn. Retrov., 13: 305 (1997); J.
Clira.
Oncol., 11: 762 (1993); Annals Oncol., 12: 289 (2001)). However, the primary body component that increased was fat, but not lean body mass.
Therefore, taken together, it is difficult to determine the actual clinical relevance, e.g., impact on morbidity, mortality, or quality of life, of the pharmacological therapies in cachectic patients. As such, there is a need for improved methods for the treatment of cachexia. In a preferred embodiment of the invention, the cachexia being treated is associated with one or more diseases, conditions and disorders selected from the group consisting of cancer, AIDS, liver cirrhosis, diabetes mellitus, chronic renal failure, chronic obstructive pulmonary disease, chronic cardiac failure, immune system diseases, tuberculosis, cystic fibrosis, gastrointestinal disorders, an aged condition and sarcopenia. In one particularly preferred embodiment, the cachexia is associated with one or more of AIDS, liver cirrhosis, diabetes mellitus, chronic renal failure, chronic obstructive pulmonary disease, chronic cardiac failure, immune system diseases, tuberculosis, cystic fibrosis, gastrointestinal disorders, an aged condition and sarcopenia.
In another particularly preferred embodiment, the cachexia is associated with one or more of cancer, AIDS, liver cirrhosis, chronic renal failure, chronic obstructive pulmonary disease, chronic cardiac failure, immune system diseases, tuberculosis, cystic fibrosis, gastrointestinal disorders, an aged condition and sarcopenia.
In yet another preferred embodiment, the cachexia is associated with one or more of ASS, liver cirrhosis, chronic renal failure, chronic obstructive pulmonary disease, chronic cardiac failure, immune system diseases, tuberculosis, cystic fibrosis, gastrointestinal disorders, an aged condition and sarcopenia. In a specific embodiment, the cachexia is associated with cancer. In another specific embodiment, the cachexia is associated with AIDS.
_28_ CANCER
As used herein, cancer refers to tumors, neoplasms, carcinomas, sarcomas, leukemias, lymphomas and the like. For example, cancers include, but are not limited to, leukemias and lymphomas such as cutaneous T-cell lymphoma (CTCL), non-cutaneous peripheral T-cell lymphoma, lymphomas associated with human T-cell lymphotropic virus (HTLV), for example, adult T-cell leukemia/lyrnphoma (ATLL), acute lymphocytic leukemia, acute nonlymphocytic leukemias, chronic lymphocytic leukemia, chronic myelogenous leukemia, Hodgkin's Disease, non-Hodgkin's lymphomas, and multiple myeloma, childhood solid tumors such as brain tumors, neuroblastoma, retinoblastoma, Wilms' Tumor, bone tumors, and soft-tissue sarcomas, common solid tumors of adults such as head and neck cancers (e.g., oral, laryngeal and esophageal), genitourinary cancers (e.g., prostate, bladder, renal, uterine, ovarian, testicular, rectal and colon), lung cancer, breast cancer, pancreatic cancer, melanoma and other skin cancers, stomach cancer, brain tumors, liver cancer, biliary cancer, gastrointestinal cancers (e.g., small intestinal, gastric) and thyroid cancer.
RETIN~~ X RECEFT~R (RXR) AG~NISTS
There are two main types of retinoid receptors that have been identified in mammals (and other organisms). The two main types or families of receptors are respectively designated the Retinoid Acid Receptors (R.ARs) and Retinoid X
Receptors (RXRs).
The Retinoid X Receptor (RXR) is a member of the nuclear hormone receptor family of proteins. RXR contains two signature domains of nuclear receptor family proteins, the DNA-binding domain and ligand binding domain (LBD). RJR
is a ligand-dependent transcription factor. The endogenous ligand for RXR is 9-cis retinoic acid. RXR plays an important role in many fundamental biological processes such as reproduction, cellular differentiation, bone development, hematopoiesis and pattern formation during embryogenesis (Mangelsdorf, D.J. et al., Cell, 83: 841-850 (1995)). RXR is also implicated in some pathological conditions as neoplastic formation and it is a potential target for cancer therapy (Nagy, L., et al., Cell Death and Diff., 5: 11-19 (1998)).
The mammalian RXR includes at least three distinct genes, RXR~, RXR~ and RXRy (RXR alpha, beta and gamma) which give rise to a large number of protein products through differential promoter usage and alternative splicing.
Compounds useful in treating cachexia can be agonists for the RXR~, RXR~ or RXRy receptor.
Besides acting as a homodimer, RXR plays a central role in regulating the activity of other nuclear hormone receptors by acting as a partner for heterodimers. RXR
forms a functional heterodimer with retinoic acid receptor (RAR), thyroid hormone receptor, vitamin D receptor, NGFI-B and many other nuclear receptors. The different binding partners of the RXR render a different DNA-binding specificity of the heterodimer.
As used herein, RXR refers to naturally occurring RXRs (e.g., mammalian RXRs (e.g., human (Homo sapien) RXRs, marine (e.g., rat, mouse) RXRs) and to proteins having an amino acid sequence which is the same as that of a corresponding naturally occurring RXR (e.g., recombinant proteins). The term includes naturally , occurring variants, such as polymorphic or allelic variants and splice variants.
As used herein, the term an RXR agonist refers to a substance (e.g., a molecule; a compound) which promotes (induces or enhances) at least one function characteristic of an RXR. In one embodiment, the R~~R agonist binds the RJR.
In certain embodiments, the agonist is a partial agonist. Partial agonist, as used herein, refers to an agonist which no matter how high of a concentration is used, is unable to produce maximal activation of the RXR. Some RXR agonists may have mixed agonist-antagonist activity.
An PAR agonist can be identified and activity assessed by any suitable method. For example a ehimeric receptor transactivation assay that tests for agonist-like activity in the RARE, R.AR~, RARy, P~R« receptor subtypes, and that is based on work published by Feigner P. L. and Holm M. Focus, 112, (1989), is described in detail in United States Patent No. 5,455,265, which is hereby incorporated by reference. In addition, a holoreceptor transactivation assay and a ligand binding assay that measure the antagonist/agonist like activity of the compounds of the invention, or their ability to bind to the several retinoid receptor subtypes, respectively, are described in WO 93/11755 (particularly on pages 30-and 37-41) published on June 24, 1993, the content ofwhich is also incorporated herein by reference. A detailed experimental procedure for holoreceptor transactivations has been described by Heyman et al., Cell 68: 397-406, (1992);
Allegretto et al., J. Biol. Chem, 268: 26625-26633, and Mangelsdorf et al., The Retinoids: Biology, Chemistry and Medicine, pp 319-349, Raven Press Ltd., New York, which are incorporated herein by reference. The results obtained in this assay and the chimeric receptor transactivation assay, are expressed as ECso values.
Still another transactivation assay, the "PGR assay" is described in Klein et al., J. Biol.

TREATMENT
Me Me Treating, as used herein, refers to a reduction in (alleviation of) at least one symptom ~of cachexia in a patient suffering from (in need of treatment for) cachexia.
Treating, as used herein, also refers to preventing the onset of at least one symptom of cachexia in a subject at risk of developing cachexia (e.g., a subject suffering from one or more of the diseases, disorders or conditions named above). Treating, as used herein, further refers to inhibiting the progression of at least one symptom of cachexia in a subject. Preferably, as with any multisymptom disorder, a reduction in or inhibition or prevention of more than one symptom is desired. The symptoms of cachexia can include loss of appetite, loss of body weight, elevation of resting energy expenditures, glucose intolerance, insulin resistance, increased fat oxidation rates, increased whole body protein turnover, decreased quality of life (e.g., decreased mobility, energy andlor stamina) and decreased life span. As such, treating of cachexia can include prevention or inhibition of appetite loss or return of appetite, prevention or inhibition of loss of body weight or an increase in body weight (e.g., as a result of preservation or restoration of lean body mass and the energy store of fat and glycogen), improvement in the patients quality of life and increased life span.
Quality of Life can be assessed by objective measurements which include nutritional and metabolic endpoints, physical function (muscle strength) and endurance (exercise tolerance). Quality of Life can also be evaluated by completing patient and caregiver questionnaires, which include standard forms such as the functional living index-cancer (FLIC), functional assessment of cancer therapy index (FACT) and the European Organization for Research and Treatment of Cancer (RORTC). The questionnaires are designed to give information regarding the effect of the drug product from a patient's and caregiver's perspective.
For the prevention or treatment of cachexia (e.g., cachexia resulting from a cancerous condition or other malignancies) it is likely that a compound of the invention is to be administered systemically. Suitable routes of administration include, but are not limited to, orally, intraperitoneally, subcutaneously, intramuscularly, intradermally, transdermally, rectally, sublingually, intravenously, buccally or via inhalation. For intravenous or intraperitoneal administration, the compound will be prepared as a solution or suspension capable of being administered by injection. In certain cases, it may be useful to formulate these compounds in suppository form or as extended release formulation for deposit under the skin or intramuscular injection. Oral admininistration of a compound in accordance with the present invention is presently preferred.
Forms suitable for oral administration include powders, pills, tablets, troches, capsules, elixirs, suspensions, syrups, wafers, chewing gum or the like prepared by art recognized procedures. The amount of active compound in such therapeutically useful compositions or preparations is such that a suitable dosage will be obtained.
The pharmaceutical compositions of the invention preferably contain a pharmaceutically acceptable carnet or diluent suitable for rendering the compound or mixture administrable orally, parenterally, intravenously, intradermally, intramuscularly or subcutaneously, rectally, via inhalation or via buccal administration, or transdermally. The active ingredients may be admixed or compounded with a conventional, pharmaceutically acceptable carrier or diluent. It will be understood by those skilled in the art that any mode of administration, vehicle or carnet conventionally employed and which is inert with respect to the active agent may be utilized for preparing and administering the pharmaceutical compositions of the present invention. Illustrative of such methods, vehicles and carriers are those described, for~example, in Remington's Pharmaceutical Sciences, 18th ed.
(1990), the disclosure of which is incorporated herein by reference.
The formulations of the present invention for use in a subject comprise the agent, together with one or more acceptable carriers or diluents therefor and optionally other therapeutic ingredients. The Garners or diluents must be "acceptable"
in the sense of being compatible with the other ingredients of the formulation and not deleterious to the recipient thereof. The formulations can conveniently be presented in unit dosage form and can be prepared by any of the methods well known in the art of pharmacy. All methods include the step of bringing into association the agent with the carrier or diluent which constitutes one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association the agent with the carriers and then, if necessary, dividing the product into unit dosages thereof.
Formulations suitable for parenteral administration conveniently comprise sterile aqueous preparations of the agents that are preferably isotonic with the blood of the recipient. Suitable Garner solutions include phosphate buffered saline, saline, water, lactated ringers or dextrose (5% in water). Such formulations can be conveniently prepared by admixing the agent with water to produce a solution or suspension, which is filled into a sterile container and sealed against bacterial contamination. Preferably, sterile materials are used under aseptic manufacturing conditions to avoid the need for terminal sterilization.
Such formulations can optionally contain one or more additional ingredients, which can include preservatives such as methyl hydroxybenzoate, chlorocresol, metacresol, phenol and benzalkonium chloride. Such materials are of special value when the formulations are presented in multidose containers.
Buffers can also be included to provide a suitable pH value for the formulation. Suitable buffer materials include sodium phosphate and acetate.
Sodium chloride or glycerin can be used to render a formulation isotonic with the blood.
If desired, a formulation can be filled into containers under an inert atmosphere such as nitrogen and can be conveniently presented in unit dose or multi-dose form, for example, in a sealed ampoule.
Those skilled in the art will be aware that the amounts of the various components of the compositions of the invention to be administered in accordance with the method of the invention to a subject will depend upon those factors noted above.
The compositions of the invention when given orally or via buccal administration can be formulated as syrups, tablets, capsules and lozenges. A
syrup formulation will generally consist of a suspension or solution of the compound or salt in a liquid carrier, for example, ethanol, glycerine or water, with a flavoring or coloring agent. Where the composition is in the form of a tablet, one or more pharmaceutical carriers routinely used for preparing solid formulations can be employed. Examples of such Garners include magnesium stearate, starch, lactose and sucrose. Where the composition is in the form of a capsule, the use of routine encapsulation is generally suitable, for example, using the aforementioned carriers in a hard gelatin capsule shell. Where the composition is in the form of a soft gelatin shell capsule, pharmaceutical carriers routinely used for preparing dispersions or suspensions can be considered, for example, aqueous gums, celluloses, silicates or oils, and are incorporated in a soft gelatin capsule shell.
A typical suppository formulation includes the conjugate or a pharmaceutically acceptable salt thereof which is active when administered in this way, with a binding and/or lubricating agent, for example, polymeric glycols, gelatins, cocoa-butter or other low melting vegetable waxes or fats.
Typical transdermal formulations include a conventional aqueous or non-aqueous vehicle, for example, a cream, ointment, lotion or paste or are in the form of a medicated plastic, patch or membrane.
Typical compositions for inhalation are in the form of a solution, suspension or emulsion that can be administered in the form of an aerosol using a conventional propellant such as dichlorodifluoromethane or trichlorofluoromethane.
A "subject" is typically a human, but can also be an animal in need of treatment, e.g., companion animals (e.g., dogs, cats, and the like), farm animals (e.g., cows, pigs, horses, sheep, goats and the like) and laboratory animals (e.g., rats, mice, guinea pigs and the like).
The therapeutically effective amount of a compound of the invention depends, in each case, upon several factors, e.g., the health, age, gender, size and condition of the subject to be treated, the intended mode of achninistration, and the capacity of the subject to incorporate the intended dosage form, among others.
A
therapeutically effective amount of an active agent is an amount sufficient to have the desired effect for the condition being treated. Desired treatment effects are discussed in detail above. A useful therapeutic or prophylactic concentration may vary with the severity of the condition being treated and the patient's susceptibility to treatment. Accordingly, no single concentration will be uniformly useful, but will require modification depending on the particularities of the disease being treated.
Such concentrations can be arrived at through routine experimentation.
A suitable dose for mammals (e.g., humans or mammals other than humans) can range from about 0.01 to about 100 mg per kg of body weight per day, such as from about 0.1 to about 75 mg per kg of body weight per day, for example, from about 1 to about 50 mg per kg of body weight per day. More preferably, the daily dose can be from about 2 to about 25 mg per kg body weight of the mammal. In a preferred embodiment, the subj ect is a human and a suitable dose is about 10 to about 4000 mg per day per subj ect, such as about 20 to about 2000 mg per day per subject, for example, about 50 to about 1000 mg per day per subject, assuming an average human of about 70 kg. More preferably, a suitable amount is in the range from about 100 to about 500 mg per day per subject.
The method of the invention can further comprise administering an additional therapeutic agent. Preferably, the additional therapeutic agent does not diminish the effects of the primary agents) and/or potentiates the effect of the primary agent(s).
In one embodiment, the additional therapeutic agent can be one that is useful for treating cachexia. For example, the additional therapeutic agent can be an anticachetic agent that has a primary mechanism of action which is different from the RXR agonists described herein. Suitable anticachetic agents include, but are not limited to, progesterone derivatives (e.g., megestrol acetate and medroxyprogesterone acetate), growth hormone (e.g,. Serostim~), growth hormone secretagogues (e.g., ghrelin, GHRP-1, GHRP-2, GHRP-6, NN703, Ipamorelin, Campromorelin, MIA-677 and those described in U.S. Patent Nos. 6,303,620, 6,576,648, 5,977,178, 6,566,337, 6,083,908, 6,274,584 and published International Application No. WO 00/01726), cannabinoids (e.g., dronabinol), anabolic steroids (e.g., oxandrolone), corticosteroids (e.g., dexamethasone), monoclonal antibodies (e.g., entanercept (ENBREL~ and REMICADE~)), ~3-Adrenergic blockers, NSAIDS, anticytokines (e.g., ,Q-2 agonist such as clenbuterol, omega-3 fatty acids, melatonin and thalidomide), metoclopramide, insulin-like growth factor-1 (see WO
96/37216), tumor necrosis factor converting enzyme inhibitors, matrix metalloproteinase inhibitors (see WO 03/090777), appetite stimulants, melanocortin receptors, serotonin receptor inhibitors and hydrazine sulfate.

EXEMPLIFICATION
FIGS. 1-5 comprise charts or graphs disclosing the results of tests obtained with experimental animals that have been inoculated with a xenograft of non-small cell lung cancer cells H292 or with small cell lung cancer cells H446, and which were then orally administered the RXR agonist Compound 1 referred to above.
FIGS. 6 and 7 disclose results of tests obtained with experimental animals that have been inoculated with a xenograft of non-small cell lung cancer cells and which were then orally administered the RXR agonist Compound 2 referred to above.
Specifically, in the experiment shown in FIG. 1 nude mice were subcutaneously transplanted with non-small cell lung cancer cells H292. A
group of the animals was given a daily oral dose of 10 mg per kilogram body weight of Compound 1 in a suitable pharmaceutically acceptable vehicle. A group of the control animals was given the vehicle only. The graph shows the body weight of the animals in grams. It can be seen that the animals treated with Compound 1 have significantly greater body weights than the animals which received the vehicle only.
FIG. 2 shows the percentage of survival of nude mice from a similar experiment as the one described in connection with FIG. 1, and demonstrates significantly better survival rate for the animals that received Compound 1 in a daily oral dose of 10 mg per kg body weight of the animal.
In the experiment shown in FIG. 3, SLID mice were subcutaneously transplanted with small cell lung cancer cells H446. A first group of the animals was given a daily oral dose of 3 mg per kilogram body weight of Compound 1 in a suitable pharmaceutically acceptable vehicle, and a second group was given a daily oral dose of 10 mg per kilogram body,weight in the same vehicle. A group of the control animals was given the vehicle only. The graph shows the body weight of the animals in grams. It can be seen that the animals treated with Compound 1 have significantly greater body weights than the animals that received the vehicle only.
In the experiment shown in FIG. 4 the right gastrocnemius muscle of the control animals and of the animals treated with Compound 1 in a daily dose of mg/kg, as described in connection with FIG. 1, was weighed after the animals had been sacrificed. It can be seen that treatment in accordance with the invention prevents muscle wasting.
In the experiment shown in FIG. 5, the food intake of nude mice with and without H292 xenografts was evaluated. Mice with H292 xenografts had reduced appetite compared with normal control. Mice treated with Compound 1 in a daily dose of 10 mg/kg body weight had equal amount of food intake as normal mice.
Therefore, adminstration of Compound 1 reverses poor appetite in cachectic animals.
In the experiment shown in FIG. 6, nude mice were subcutaneously transplanted with non-small cell lung cancer cells H292. A group of the animals was given a daily oral dose of 50 mg per kilogram body weight of Compound 2 in a suitable pharmaceutically acceptable vehicle. A group of the control animals was given the vehicle only. The graph shows the body weight of the animals in grams. It can be seen that the animals treated with Compound 2 have significantly greater body weights than the animals which received the vehicle only.
In the experiment shown in FIG. 7, the food intake of nude mice bearing H292 xenografts was evaluated. Mice treated with Compound 2 in a daily dose of mg/kg body weight had significantly larger food intake than the tumor bearing mice which received only vehicle. Therefore, adminstration of Compound 2 significantly increases the appetite of tumor bearing animals.
While this invention has been particularly shown and described with references to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention encompassed by the appended claims.
