Patent Application
20110160225
The subject matter of this application relates to fibric acid and statin derivatives, and pharmaceutical formulations thereof, used alone or in combination with one or more additional agents for treating lipid related disorders and associated conditions.
Disorders of lipid metabolism or dyslipidemias include various conditions characterized by abnormal concentrations of one or more lipids (i.e., cholesterol and triglycerides), and/or apolipoproteins (i.e., apolipoproteins A, B, C and E), and/or lipoproteins (i.e., the macromolecular complexes formed by the lipid and the apolipoprotein that allow lipids to circulate in blood, such as LDL, VLDL and IDL). Dyslipidemia is a major risk factor for cardiovascular disorders including coronary heart disease. Dyslipidemias were originally classified by Fredrickson according to the combination of alterations mentioned above. The Fredrickson classification includes 6 phenotypes (i.e., I, IIa, IIb, III, IV and V) with the most common being the isolated hypercholesterolemia (or type IIa), which is usually accompanied by elevated concentrations of total and LDL cholesterol. A second common form of dyslipidemia is the mixed or combined hyperlipidemia or type IIb and III of the Fredrickson classification. This dyslipidemia is often prevalent in patients with type 2 diabetes, obesity and the metabolic syndrome.
The management of dyslipidemia is an important part of the National Cholesterol Education Program Adult Treatment Panel III guidelines. The reduction of low-density lipoprotein cholesterol as the primary target of treatment is recommended. Various lipid altering agents are considered first-line drugs for attaining this goal. However, monotherapy may not always be optimal for patients with significant combined or mixed dyslipidemias (e.g., elevated low-density lipoprotein cholesterol plus hypertriglyceridemia) or with concomitant conditions that increase the patient's level of risk (e.g., type 2 diabetes or the metabolic syndrome). Accordingly, combination drug therapy, which utilizes complementary mechanisms of action to alter levels of one or more lipoproteins may be useful.
It would be desirable to develop an effective treatment for management of lipid related disorders using fibric acid and statin derivatives that can be administered alone or in combination with one or more lipid altering agents. Lipid altering agents encompass several classes of drugs that include HMG CoA reductase inhibitors (statins), fibric acid derivatives (fibrates), cholesterol-ester-transfer-protein (“CETP”) inhibitors, squalene synthase inhibitors, microsomal-triglyceride-transfer-protein (“MTTP”) inhibitors, cholesterol absorption inhibitors (“CAIs”), soluble guanylate cyclase modulators (“sGC modulators”), bile acid sequestrants, nicotinic acid, thyroid receptor agonists, liver X-receptor (LXR) modulators, antisense inhibitors of apoB-100 or C reactive protein, and probucol and derivatives thereof (e.g. AGI-1067). These drugs differ with respect to mechanism of action and to the degree and type of lipid modulation. Thus, the indications for a particular drug are influenced by the underlying lipid abnormality. Monotherapy with statins, which competitively inhibit the intracellular rate-limiting enzyme for cholesterol biosynthesis, and bile acid sequestrants, which reduce terminal ileal bile acid absorption, primarily lower plasma low-density lipoprotein (LDL) cholesterol by enhancing hepatic LDL-receptor activity. Monotherapy with fibrates, which serve as ligands for peroxisome proliferator-activated receptor a, a transcription factor influencing gene expression in lipid metabolism, reduces plasma very-low-density lipoprotein (VLDL) cholesterol and triglycerides, and also increases high-density lipoprotein (HDL) cholesterol.

No. 4,613,610, EP0221025, and EP491226, and optical or geometric isomers thereof and nontoxic pharmaceutically acceptable salts, N-oxides, esters, quaternary ammonium salts, and prodrugs thereof. In HMG-CoA reductase inhibitors where an open-acid form can exist, salt and ester forms may preferably be formed from the open-acid, and all such forms are included within the meaning of the term “HMG-CoA reductase inhibitor” as used herein. Pharmaceutically acceptable salts with respect to the HMG-CoA reductase inhibitor includes non-toxic salts of the compounds which are generally prepared by reacting the free acid with a suitable organic or inorganic base, particularly those formed from cations such as sodium, potassium, aluminum, calcium, lithium, magnesium, zinc and tetramethylammonium, as well as those salts formed from amines such as ammonia, ethylenediamine, N-methylglucamine, lysine, arginine, ornithine, choline, N,N′-dibenzylethylenediamine, chloroprocaine, diethanolamine, procaine, N-benzylphenethylamine, 1-p-chlorobenzyl-2-pyrrolidine-1′-yl-methylbenzim-idazole, diethylamine, piperazine, and tris(hydroxymethyl)aminomethane.

Other suitable statins, or statin prodrugs, are disclosed in PCT/US2006/018616, filed May 15, 2006, which is incorporated herein by reference. Those of skill in the art would recognize that any of these statins can be used to formulate the statin derivative compounds according to the methods disclosed herein.
Most of the compounds described herein contain one or more asymmetric centers and may thus give rise to enantiomers, diastereomers, and other stereoisomeric forms that may be defined, in terms of absolute stereochemistry, as (R)- or (S)- or, as (D)- or (L)- for amino acids. The present disclosure is meant to include all such possible isomers, as well as, their racemic and optically pure forms. Optically active (R)- and (S)-, or (D)- and (L)-isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. When the compounds described herein contain olefinic double bonds or other centers of geometric asymmetry, and unless specified otherwise, it is intended that the compounds include both E and Z geometric isomers. Likewise, all tautomeric forms are also intended to be included.
Terminology related to “protecting”, “deprotecting” and “protected” functionalities occurs throughout this application. Such terminology is well understood by persons of skill in the art and is used in the context of processes which involve sequential treatment with a series of reagents. In that context, a protecting group refers to a group which is used to mask a functionality during a process step in which it would otherwise react, but in which reaction is undesirable. The protecting group prevents reaction at that step, but may be subsequently removed to expose the original functionality. The removal or “deprotection” occurs after the completion of the reaction or reactions in which the functionality would interfere. Thus, when a sequence of reagents is specified, as it is in the processes of the present disclosure, the person of ordinary skill can readily envision those groups that would be suitable as “protecting groups”.
In the case of the present disclosure, the functionalities that must be protected are carboxylic acids and alcohols. Suitable groups for that purpose are discussed in standard textbooks in the field of chemistry, such as Protective Groups in Organic Synthesis by T. W. Greene [John Wiley & Sons, New York, 1991], which is incorporated herein by reference. Particular attention is drawn to the chapters entitled “Protection for the Hydroxyl Group, Including 1,2- and 1,3-Diols” (pages 10-86) and “Protection for the Carboxyl Group” (pages 152-end).
As used herein, “treating” or “treatment of” a condition or subject refers to taking steps to obtain beneficial or desired results, including clinical results. For purposes of this disclosure, beneficial or desired clinical results include, but are not limited to, alleviation or amelioration of one or more disease, symptom, or condition related to lipid metabolism disorders, fatty liver disease, hepatitis, or erectile dysfunction.
As used herein, a “therapeutically effective amount” of a drug or pharmaceutical composition or formulation, or agent, described herein is an amount of a drug or agent that, when administered to a subject with a disease or condition, will have the intended therapeutic effect, e.g., alleviation, amelioration, palliation or elimination of one or more manifestations of the disease or condition in the subject. The full therapeutic effect does not necessarily occur by administration of one dose and may occur only after administration of a series of doses. Thus, a therapeutically effective amount may be administered in one or more administrations.
As used herein, a “prophylactically effective amount” of a drug or pharmaceutical composition or formulation, or agent, described herein is an amount of a drug or agent that, when administered to a subject, will have the intended prophylactic effect, e.g., preventing or delaying the onset (or reoccurrence) of disease or symptoms, or reducing the likelihood of the onset (or reoccurrence) of disease or symptoms. The full prophylactic effect does not necessarily occur by administration of one dose and may occur only after administration of a series of doses. Thus, a prophylactically effective amount may be administered in one or more administrations.
As used herein, and as would be understood by the person of skill in the art, the recitation of “a compound” or “a composition” is intended to include salts, solvates and inclusion complexes of that compound as well as any stereoisomeric form, or a mixture of any such forms of that compound in any ratio.
The term “pharmaceutically acceptable salt” refers to salts prepared from pharmaceutically acceptable non-toxic acids or bases including inorganic acids and bases and organic acids and bases. When the compounds of the present disclosure are basic, salts may be prepared from pharmaceutically acceptable non-toxic acids including inorganic and organic acids. Suitable pharmaceutically acceptable acid addition salts for the compounds of the present disclosure include acetic, benzenesulfonic (besylate), benzoic, camphorsulfonic, citric, ethenesulfonic, fumaric, gluconic, glutamic, hydrobromic, hydrochloric, isethionic, lactic, maleic, malic, mandelic, methanesulfonic, mucic, nitric, pamoic, pantothenic, phosphoric, succinic, sulfuric, tartaric acid, p-toluenesulfonic, and the like. When the compounds contain an acidic side chain, suitable pharmaceutically acceptable base addition salts for the compounds of the present disclosure include metallic salts made from aluminum, calcium, lithium, magnesium, potassium, sodium and zinc or organic salts made from lysine, N,N′-dibenzylethylenediamine, chloroprocaine, choline, diethanolamine, ethylenediamine, meglumine (N-methylglucamine) and procaine.
Administration of any of the compositions or formulations described in detail herein includes parallel administration (i.e., administration of elements of the formulation to the subject over a period-of time), co-administration or sequential administration (in which elements of the formulation are administered at approximately the same time, e.g., within about a few seconds to a few hours of one another), and simultaneous or co-formulation (in which elements of the formulation are combined or compounded into a single dosage form suitable for oral or parenteral administration).
Combination therapy can be achieved by administering two or more agents, e.g., a fibric acid, a statin, a fibric acid derivative or a statin derivative in combination with one or more agents chosen from lipid altering agents, resveratrol, imidazoline receptor agonists, and PDE inhibitors, each of which is formulated and administered separately, or by administering two or more agents in a single formulation. For example, a fibric acid compound or a statin compound can be combined with one or more of (1) an amino-containing compound such as, but not limited to, aminoguanidine, agmatine, or amino-tetrazole, (2) resveratrol and (3) an imidazoline receptor agonist such as, but not limited to, LNP509, S-21663, S-22068, or S-23515. This combination can be accomplished by addition of the separate agents or by direct chemical coupling of the agents as disclosed herein to form a single compound. One or more lipid altering agents and/or PDE inhibitors can also be included in the fibric acid/statin/(amino-containing compound/resveratrol/imidazoline receptor agonist) combination. Each of the agents can be formulated and administered separately, or in a single formulation. Other combinations are also encompassed by combination therapy. For example, two agents can be formulated together and administered in conjunction with a separate formulation containing a third agent. While the two or more agents in the combination therapy can be administered simultaneously, they need not be. For example, administration of a first agent (or combination of agents) can precede administration of a second agent (or combination of agents) by minutes, hours, days, or weeks. Thus, the two or more agents can be administered within minutes of each other or within 1, 2, 3, 6, 9, 12, 15, 18, or 24 hours of each other or within 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14 days of each other or within 2, 3, 4, 5, 6, 7, 8, 9, or 10 weeks of each other. In some cases even longer intervals are possible. While in many cases it is desirable that the two or more agents used in a combination therapy be present in within the patient's body at the same time, this need not be so.
Combination therapy can also include two or more administrations of one or more of the agents used in the combination. For example, if agent X and agent Y are used in a combination, one could administer them sequentially in any combination one or more times, e.g., in the order X-Y-X, X-X-Y, Y-X-Y, Y-Y-X, X-X-Y-Y, etc.
A “subject” or “patient” is a mammal, preferably a human, but can also be an animal in need of veterinary treatment, e.g., companion animals (e.g., dogs, cats, and the like), farm animals (e.g., cows, sheep, pigs, horses, and the like) and laboratory animals (e.g., rats, mice, guinea pigs, and the like).
A “susceptible individual” or “patient in need thereof” is an individual who suffers from, is suffering from, or is likely to or predisposed to suffer from a disorder or associated condition contemplated of being treated by the compositions described in detail herein. In humans these conditions may include, for example, dyslipidemia, hyperlipidemia, hypercholesterolemia, hypertriglyceridemia, sitosterolemia, erectile dysfunction, fatty liver disease, and hepatitis.
As used herein, the term “nitric oxide donor” is also interchangeably used herein and in the art with “NO prodrugs” or “NO-donating agents,” which refer to compounds that release free nitric oxide when administered to a patient, compounds that donate, release and/or directly or indirectly transfer a nitrogen monoxide species, and/or stimulate the endogenous production of nitric oxide or endothelium-derived relaxing factor (EDRF) in vivo and/or elevate endogenous levels of nitric oxide or EDRF in vivo and/or are oxidized to produce nitric oxide and/or are substrates for nitric oxide synthase and/or cytochrome P450.
The fabric acid or statin derivative compositions disclosed herein can be used for preventing and/or treating a “lipid related disorder” or “lipid metabolism disorder” including, for example: reducing blood plasma or serum concentrations of LDL cholesterol; reducing concentrations of cholesterol and cholesterol ester in the blood plasma or serum; reducing blood plasma or serum concentrations of apolipoprotein B; reducing blood plasma or serum concentrations of triglycerides; increasing blood plasma or serum concentrations of high density lipoprotein (HDL) cholesterol; increasing fecal excretion of cholesterol; inhibiting the absorption of or reducing plasma or tissue concentration of one or more sterols or stanols; preventing or treating sistoserolemia; preventing or treating vascular diseases/disorders and conditions (including, but not limited to, arteriosclerosis, atherosclerosis, cardiovascular disease, cerebrovascular disease, renovascular disease, mesenteric vascular disease, pulmonary vascular disease, ocular vascular disease and peripheral vascular disease), hyperlipidemia (including, but not limited to, hypercholesterolemia, hypertriglyceridemia, sitosterolemia), hypertension, angina, cardiac arrhythmias, congestive heart failure, and stroke; reducing the incidence of cardiovascular disease-related events; preventing or treating vascular conditions and associated thrombotic events and blood clotting disorders; preventing or treating inflammation (including, but not limited to, vascular inflammation); reducing blood plasma or serum concentrations of C-reactive protein; preventing, treating, or ameliorating symptoms of Alzheimer's Disease (AD) or other neurodegenerative diseases; regulating production or levels of at least one amyloid β (Aβ) peptide; regulating the amount of ApoE isoform 4 in the bloodstream and/or brain; slowing the aging process and reducing stress-related disorders; preventing or treating obesity; preventing or decreasing the incidence of xanthomas; preventing or minimizing muscular degeneration and related side effects associated with certain HMG-CoA reductase inhibitors (statins); preventing or treating diabetes and associated conditions; preventing or treating at least one autoimmune disorder; preventing or treating demyelination and associated disorders; preventing or treating cancer (including, but not limited to, cholesterol associated tumors); inhibiting the expression of at least one multiple (“multi”)-drug resistance gene or protein in an animal cell; enhancing the effectiveness of a chemotherapeutic agent in a subject having cancer; reversing a multi-drug resistance phenotype exhibited by an animal cell; and preventing or treating osteopenia disorders (bone loss disorders).
For example, in certain aspects, the application provides methods for the following: improving lipid parameters in diabetic and non-diabetic patients; improving glycemic control in both Type 2 diabetics and “pre-diabetic” individuals who exhibit elevated fasting plasma glucose and/or insulin resistance; reducing glycosylated hemoglobin levels (HbA1c); lowering fasting plasma glucose (FPG) levels; reducing peak and 2-hour post-prandial glucose (PPG) levels; improving insulin sensitivity; reducing insulin resistance; and increasing insulin secretion. The methods are performed by administering to the patient in need thereof a therapeutically effective amount of one or more of the compounds, salts, and/or compositions disclosed herein.
Furthermore, based on rationale that it has been shown that improved glycemic control can reduce the risk of diabetes-associated morbidity and mortality (as demonstrated by the DCCT (Diabetes Control and Complications Trial. Diabetes. 1996 October; 45(10):1289-98), DCCT/EDIC (Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications Trial.

Soluble guanylate cyclase modulators are dyslipidemic agents that can be used in therapeutic combinations with compounds described herein. Soluble guanylate cyclase (sGC) is a nitric oxide (NO) sensing haemprotein that has been described in many eukaryotes. In response to various stimuli sGC converts GTP into the 2nd messenger cyclic cGMP. GC is a heterodimeric protein consisting of homologous alpha and beta subunits. Each subunit consists of an N-terminal domain which may bind haem-nitric oxide and/or oxygen, a central domain of unknown function, and a C-terminal consensus nucleotide cyclase domain. sGC can be activated via both nitric oxide (NO) dependent and independent manners. When NO binds to the haem prosthetic group in the beta subunit of sGC, catalysis is accelerated by 2-3 orders of magnitude. Agents that function as sGC modulators include but are not limited to: NO donors, eNOS transcriptional enhancers, haem-dependent sGC stimulators, haem-independent sGC activators and NOS substrates.
NO donors are pharmacologically active substances that release NO in vivo or in vitro. There are different classes of NO donors, which include organic nitrates (e.g., nitroglycerin, isosorbides (e.g. isosorbide dinitrate, isosorbide mononitrate, isosorbide 5-mononitrate, isosorbide 2-mononitrate, CA Registry no. 16051-77-7), S-nitrosothiols, iron-nitrosyl complexes (e.g., sodium nitroprusside), sydnonimines, C-nitroso compounds, and secondary amine/NO complex ions.
Specific examples of some of the classes of NO donors named above include: Isosorbide (Dilatrate®-SR, Imdur®, Ismo®, Isordil®, Isordil® Titradose®, Monoket®), FK 409 (NOR-3); FR 144420 (NOR-4); 3-morpholinosydnonimine; Linsidomine chlorohydrate (“SIN-1”); S-nitroso-N-acetylpenicillamine (“SNAP”); AZD3582 (CINOD lead compound), NCX 4016, NCX 701, NCX 1022, HCT 1026, NCX 1015, NCX 950, NCX 1000, NCX 1020, AZD 4717, NCX 1510/NCX 1512, NCX 2216, and NCX 4040 (all available from NicOx S.A.), S-nitrosoglutathione (GSNO), S-nitrosoglutathione mono-ethyl-ester (GSNO-ester), 6-(2-hydroxy-1-methyl-nitrosohydrazino)-N-methyl-1-hexanamine (NOC-9) or diethylamine NONOate, S-nitrosothiol, a nitrite, a sydnonimine, a NONOate, a N-nitrosoamine, a N-hydroxyl nitrosamine, a nitrosimine, a diazetine dioxide, an oxatriazole 5-imine, an oxime, a hydroxylamine, a N-hydroxyguanidine, a hydroxyurea or a furoxan. Nitric oxide donors are also as disclosed in U.S. Pat. Nos. 5,155,137; 5,366,997; 5,405,919; 5,650,442; 5,700,830; 5,632,981; 6,290,981; 5,691,423; 5,721,365; 5,714,511; 6,511,911; and 5,814,666, Chrysselis et al. (2002) J Med Chem. 45:5406-9 (such as NO donors 14 and 17), and Nitric Oxide Donors for Pharmaceutical and Biological Research, Eds: Peng George Wang, Tingwei Bill Cai, Naoyuki Taniguchi, Wiley, 2005.
NO donors have a nitrate functionality within the molecule, and a nitroso functional group is present in all of these compounds. Glyceryl trinitrate (also known as GTN, nitroglycerin, nitroglycerine, and trinitrogylcerin) is the nitrate ester of glycerol. In sodium nitroprusside (SNP) a molecule of nitric oxide is coordinated to iron metal forming the square bipyramidal complex. 3-Morpholinosydnonimine (SIN-1) is a zwitterionic compound formed by combination of a morpholine and a sydnonimine. S-nitroso-N-acetylpenicillamine (SNAP) is an N-acetylated amino acid derivative with a nitrosothiol functional group. Diethylenetriamine/NO (DETA/NO) is a compound of nitric oxide covalently linked to diethylenetriamine. NCX 4016 is an m-nitroxymethyl phenyl ester of acetyl salicyclic acid.
The amount and duration of NO release by the respective NO donors determines their pharmacological properties. In vivo, some compounds act rapidly, and the amount of NO released is relatively small. In others, such as NCX 4016 (NO aspirin), the effect is slow and lasts for hours. The route of administration (oral and parenteral) and the duration of release of NO also differ. NO is connected with a specific molecular target; by binding to iron in the haem group of sGC, it produces cyclic guanosine monophosphate (cGMP), which activates a cascade of cellular processes.
The classic nitrovasodilators, organic nitrate and nitrite esters, including nitroglycerin, amyl nitrite, isosorbide dinitrate, isosorbide 5-mononitrate, and nicorandil, have been used for many years in the treatment of cardiovascular diseases. Their principal action is vasorelaxation/vasodilation, mediated by guanylyl cyclase activation and by direct inhibition of nonspecific cation channels in vascular smooth muscle cells (VSMCs). As such, these agents represent the prototypical form of NO-replacement therapy. All of the organic nitrate esters are prodrugs requiring enzymatic metabolism to generate bioactive NO. The major enzyme system involved is located within microsomal membranes, has an estimated apparent molecular mass of 160 kDa, and manifests enhanced activity in the presence of reducing equivalents, especially thiols, which potentiate the action of organic nitrate esters. Although the enzyme has not been more specifically characterized, growing evidence suggests that the cytochrome P-450 system, in conjunction with NADPH and glutathione-S-transferase activities, is required for the linked metabolic processes of denitration and reduction of organic nitrate esters to authentic NO.

Iodoester 3A is coupled to styrene 7A in the presence of palladium (II) acetate, tri-o-tolylphosphine and triethylamine (Heck coupling conditions) to give (E)-5-(4-(2-(4-(4-chlorobenzoyl)phenoxy)-2-methylpropanoyloxy)styryl)-1,3-phenylene diacetate (8A) as off-white needles in 85% yield (mp: 112-113° C.).
In the second step the acetate groups of 8A can be selectively removed by careful hydrolysis with HCl to give the bis-phenol (10A) as a light tan foam in 71% yield.

Methods of synthesis and specific experimental for representative compounds in the genus of Formula (II) include the following:
In still other embodiments, the present disclosure provides compounds comprising a fibric acid or statin derivative in the form of a salt, wherein a fibric acid or statin residue is provided as a cation or anion, and another molecule is provided as a corresponding counterion. In certain embodiments, the counterion includes, but is not limited to, a NOS substrate or an amino-tetrazole compound. Although those of ordinary skill in the art would recognize that any fibric acid or statin compound can be used, along with counterions other than those disclosed immediately below, methods of synthesis and specific experimental for representative compounds include the following:
Although the foregoing Examples demonstrate and depict synthesis routes of particular embodiments of fibric acid and statin derivative compounds described herein, this has been done for purposes of illustration only, and is not intended to be limiting to a particular fibric acid or statin compound, to the way in which the fibric acid or statin compound is linked to another molecule, or to be limiting with respect to the scope of the appended claims that follow. Using the knowledge contained within the present disclosure and using the manner of making the various embodiments of fibric acid and statin derivative compounds illustrated herein, those skilled in the art would recognize that other fibric acid and/or statin derivative compounds could be readily formulated by using molecules and linkages other than those illustrated and described herein. Such other fibric acid and/or statin derivative compounds could be achieved by routine experimentation and would function in a similar manner to accomplish the same objectives as those fibric acid and statin derivative compounds illustrated and described herein, and thus, should not be considered as departing from the true scope and spirit of the present disclosure.
Compounds of the present disclosure can be assayed for activity in liver function tests (Kaplan M M. Laboratory tests. In: Schiff L, Schiff E R, eds. Diseases of the liver. 7th ed. Philadelphia: Lippincott, 1993:108-44). Liver function tests are commonly performed clinical laboratory tests which assay for a number of protein, enzymatic, metabolite and other cellular properties and activities. For example, one enzyme commonly assayed in liver function tests is alanine aminotransferase (ALT; also known as SGPT) which is produced in hepatocytes and is involved in liver degradation. ALT elevation is associated with numerous liver disorders and is a consequence of certain medications which inhibit liver function. A second commonly assayed enzyme in liver function tests is aspartate Aminotransferase (AST; also known as SGOT). AST is needed for energy utilization and is present in muscle, liver and other organs. AST elevation has been associated with liver disease and other conditions (for example, early in the course of a heart attack).
The ability of compounds of the present disclosure to antagonize liver X receptor (LXR) activity can be determined using assays similar to those described in Thomas et al. (2003) J Biol Chem 278:2403-10. Briefly, the protocol is as follows. The human hepatocellular carcinoma cell line, HepG2 (HB-8065; American Type Culture Collection, Manassas, Va.), is maintained in monolayer culture at 37° C. in 5% CO2. For transient transfection of HEK293 cells, 4×104 cells are plated into 24-well dishes. HEK293 cells are co-transfected either with either 100 ng of pGL3B-E1b-3XLXRE (LXR response element luciferase reporter plasmid), 100 ng of pCMV6 LXRα (NR1H3, accession number NM—005693), and 50 ng of CMV β-galactosidase or with the Gal4-responsive luciferase plasmid (pGSluc; Promega, Madison, Wis.), an expression plasmid encoding LXRα-LBD (amino acids 162-447) fused to the GAL4 DNA-binding domain (pM LXRα-LBD), and CMV β-galactosidase, as control. After transfection, cells are treated either with vehicle only or one or more compounds of the present disclosure. Following 24 hours of treatment, cells are lysed and firefly luciferase activity is measured using standard luciferase substrate reagents (BD PharMingen, San Diego, Calif.) and is corrected using β-galactosidase activity as a transfection control.
The fibrate and statin derivatives described herein, alone and in combination with other therapeutic agents can be tested for effects on lipid and cholesterol profiles in various lipid and cholesterol related animal models.
Fibrate and statin derivatives, alone and in combination, are tested for the ability to prevent or arrest atherosclerosis in a rabbit model of familial hypercholesterolemia. Fibrate and statin derivatives can be administered before or after onset of atherosclerosis for example as described in Havel et al. (1989) Arteriosclerosis 9:133-8, Aliev and Burnstock (1998) Histol Histopathol 13:797-817, Fan et al. (1999) Pathol Int. 49:583-94 and Brousseau and Hoeg (1999) J Lipid Res. 40:365-75.
Fibrate and statin derivatives, alone and in combination, are tested for effects on cholesterol and lipid profiles in a rat high fat diet model for example as described in Ghibaudi et al. (2002) Obes Res 10:956-63, Ricci and Levin (2003) Am J Physiol Regul Integr Comp Physiol 285:R610-8, and Gao et al. (2002) 936:87-90. Alternatively, animals are fed either a normal diet or a chow supplemented with added fat and/or cholesterol as described in Krause et al (1994) Pharm Res Vol 29, No. 4, Nishina (1993) J of Lipid Res vol 43. and Gajda et al. (2007) Animal Lab News. Based on the specific chows used in these reports, we fed animals a diet consisting of 40% fat, 1% cholesterol, and 0.5% cholic acid (catalog #D01061201, Research Diets, New Brunswick, N.J. 08901). After at least a week on this diet, animals (6-8/group) are dosed once daily perorally with 300 uL test compounds in PEG 400 or suitable vehicle. Groups are dosed for at least one week before whole blood samples are taken for analysis. Blood serum is analyzed using Vertical Auto Profile (VAP; Atherotech, Inc., Birmingham, Ala.) analysis similar to as described in Kulkarni (2006) Clin Lab Med 26:787-802.
In this assay, Compound 10A [(E)-4-(3,5-dihydroxystyryl)phenyl 2-(4-(4-chlorobenzoyl)phenoxy)-2-methylpropanoate] was associated with dose related decreases of LDL and VLDL, decreased blood glucose, and increased HDL. Similarly, when tested in this assay, Compound 5A [(E)-4-(3,5-dimethoxystyryl)phenyl 2-(4-(4-chlorobenzoyl)phenoxy)-2-methylpropanoate] was associated with decreased LDL and VLDL, no change in blood glucose, and increased HDL. Graphical depictions showing the LDL, VLDL and HDL analyses for compounds 10A and 5A are shown in
Mice homozygous for the obese (ob) mutation exhibit a diabetes-like syndrome of hyperglycemia, hypercholesterolemia and increased triglycerides (Nishina 1994, Metabolism, Vol 43, No 5). The increased expression of plasma lipids in ob/ob mice make them a useful model for the study of drugs designed to lower cholesterol. In these experiments animals (n=10 per group) were fed a high fat chow (HF; 60% fat,) for one week before test compound administration and continued on this diet for the duration of the experiment. Animals received either vehicle only (PEG 400), or test compound (Compound 121 (resveratrol) at 43 or 1000 mg/kg, Compound 10A at 30 or 100 mg/kg, or fenofibrate at 68 mg/kg) perorally once daily for a total of three weeks. Blood samples were collected weekly for the determination of fasting glucose levels (One touch Ultra, LifeScan Inc). Blood serum was analyzed after three weeks using Vertical Auto Profile (VAP; Atherotech, Inc., Birmingham, Ala.) analysis similar to as described in Kulkarni (2006) Clin Lab Med 26:787-802. Compound 10A exhibited statistically significant (when compared to day 0) decreases in blood glucose at days 7, 14, and 21 when tested at both 30 and 100 mg/kg (
Fibrate and statin derivatives, alone and in combination, are tested for effects on cholesterol and lipid profiles in a hamster high fat diet model for example as described in Wang et al. (2001) Eur J. Pharmacol 427:285-93 and van Heek et al. (2001) Diabetes 50:1330-5.
Various pharmacokinetic parameters were calculated by collecting plasma samples from animals dosed with a test compound and analyzed by LC/MS-MS. Blood samples were collected at specified time points into tubes containing NaEDTA/NaF. Additional amounts of NaF and NaEDTA were added to the tubes prior to collection so the final concentration was 4 mg/mL of each NaF and NaEDTA. All blood samples were placed on wet ice (or an ice block) and protected from light exposure following collection. The samples were centrifuged and the plasma was separated and immediately transferred into amber tubes upon centrifugal separation. Following separation, 40 μL of 5 M sodium formate pH 4.0 buffer was added for every 1 mL of plasma collected. Samples were stored frozen within 15 minutes of centrifugation at approximately −80° C. Samples (10 μL injections) were separated using a reverse phase HPLC column (Thermo Electron Hypersil Gold C18, 2.1×50 mm, 5 um particle size) with gradient elution (Mobile Phase A: 0.05% v/v acetic acid in 95:5 water:acetonitrile; Mobile Phase B: 0.05% acetic acid v/v in 5:95 water:acetonitrile) at 0.4 mL/min with a gradient-time profile as follows: initial condition of 15% B, ramping to 40% B over 1.5 min, ramping to 55% B over the next 0.5 min, ramping to 100% B over the next 0.5 minutes with a 1.6 min hold at 100% B. The column was allowed to re-equilibrate at 15% B for 0.9 min. A Waters Quattro micro (Waters Corp.; Milford, Mass.) triple quadrupole mass spectrometer operating in MRM mode was used to detect test compounds as they eluted from the HPLC column using characteristic precursor-to-product ion transitions. Concentrations were determined by relative responses to an internal standard and calculated based on a standard concentration curve of the test compound. MassLynx software (Waters, Corp.; Milford, Mass.) was used to calculate the absolute concentration of the test compound in each plasma sample and exported into Microsoft Excel (Microsoft Corp., Redmond, Wash.) or Graphpad Prism (GraphPad Software, Inc., San Diego, Calif.) for analysis. A concentration versus time plot was generated from the data in Graph Pad Prism to generate PK curves and calculate the AUCn (Area Under the Curve, n=length of experiment in hours) for both intravenous (IV) and orally dosed animals. Oral Bioavailability (Fn) was calculated using the equation: F=(AUCoral/AUCIV)*DoseIV Doseoral). Cmax and Tmax are determined by visual inspection of the oral concentration curve. Cmax is the maximum concentration of the test compound circulating in the blood through the duration of the experiment reported at time, T (Tmax).
Resveratrol pharmacokinetic profiles were determined after oral administration of either Compound 10A or Compound 121 (resveratrol) in either the obese mouse model (
Combination Therapy with PDE Inhibitors
The fibric acid and statin derivative compounds and compositions described herein can be used in combination therapy (for example in methods to treat a lipid related disorder) with one or more phosphodiesterase inhibitors. Phosphodiesterase (PDE) inhibitors slow the degradation of cyclic AMP (cAMP) and/or cyclic GMP (cGMP) by inhibition of the phosphodiesterases, which can lead to a relative increase in the intracellular concentration of cAMP and cGMP. Thus, co-administration of fibric acid and statin derivative compounds or compositions and PDE inhibitors which slow the degradation of cGMP by phosphodiesterases is useful for treating lipid metabolism related disorders.
PDE inhibitors include PDE3 inhibitors, PDE4 inhibitors, PDE5 inhibitors, and inhibitors with multiple specificity including PDE3/4 and PDE3/4/5 inhibitors. Specific PDE inhibitors include those disclosed in patent publications DE1470341, DE2108438, DE2123328, DE2305339, DE2305575, DE2315801, DE2402908, DE2413935, DE2451417, DE2459090, DE2646469, DE2727481, DE2825048, DE2837161, DE2845220, DE2847621, DE2934747, DE3021792, DE3038166, DE3044568, EP000718, EP0008408, EP0010759, EP0059948, EP0075436, EP0096517, EP0112987, EP0116948, EP0150937, EP0158380, EP0161632, EP0161918, EP0167121, EP0199127, EP0220044, EP0247725, EP0258191, EP0272910, EP0272914, EP0294647, EP0300726, EP0335386, EP0357788, EP0389282, EP0406958, EP0426180, EP0428302, EP0435811, EP0470805, EP0482208, EP0490823, EP0506194, EP0511865, EP0527117, EP0626939, EP0664289, EP0671389, EP0685474, EP0685475, EP0685479, JP92234389, JP94329652, JP95010875, U.S. Pat.

The present disclosure provides, in various embodiments, pharmaceutical combination kits and oral drug dosage forms that contain at least one fibric acid and/or statin derivative composition and at least one lipid altering agent or phosophodiesterase inhibitor. In other embodiments, the present disclosure provides pharmaceutical combinations kits and oral dosage forms that contain at least one fibric acid and/or statin derivative composition and at least one lipid altering agent and/or at least one phosophodiesterase inhibitor. The therapeutic agents may be contained in the same oral dosage form or in separate dosage forms that are administered sequentially. When more than two therapeutic agents are present in the pharmaceutical combination kit, all agents may be present in the same or different dosage forms and may be administered sequentially or simultaneously.
The active ingredients used in oral formualtions, i.e., fibric acid and statin derivative compositions, either alone or in combination with one or more additional agents (e.g., lipid altering agents or PDE inhibitors), are well known in the art and many are commercially available. If desired, drugs can also be manufactured using methodology well known in the art.
The pharmaceutical compositions may include a “pharmaceutically acceptable inert carrier”, and this expression is intended to include one or more inert excipients, which include starches, polyols, granulating agents, microcrystalline cellulose, diluents, lubricants, binders, disintegrating agents, and the like. If desired, tablet dosages of the disclosed compositions may be coated by standard aqueous or nonaqueous techniques. “Pharmaceutically acceptable carrier” also encompasses controlled release means.
Compositions of the present disclosure may also optionally include other therapeutic ingredients, anti-caking agents, preservatives, sweetening agents, colorants, flavors, desiccants, plasticizers, dyes, and the like. Any such optional ingredient must, of course, be compatible with the compound of the disclosure to insure the stability of the formulation.

It can be useful to administer a fibric acid or statin derivative composition or pharmaceutical formulation described herein together with an HMG-CoA reductase inhibitor such as a statin, or with a PDE inhibitor. It can be particularly useful to combine a fibric acid or statin derivative composition described herein together and an HMG-CoA reductase inhibitor such as a statin, or a PDE inhibitor, in a single pharmaceutical composition. The precise amount of each of these two active ingredients in a dosage unit will depend on the desired dosage of each component. Thus, it can be useful to create a dosage unit that will, when administered according to a particular dosage schedule (e.g., a dosage schedule specifying a certain number of units and a particular timing for administration), deliver the same dosage of each component as would be administered if the patient was being treated with only a single component. In other circumstances, it might be desirable to create a dosage unit that will deliver a dosage of one or both components that is less than that which would be administered if the patient was being treated only with a single component. Finally, it might be desirable to create a dosage unit that will deliver a dosage of one or both components that is greater than that which would be administered if the patient was being treated only with a single component. The pharmaceutical composition can include additional ingredients such as stabilizers or bulking agents.
Making of Pharmaceutical Preparations: The active agents used in the compositions of the present disclosure will typically be formulated in accordance with methods that are standard in the art (see e.g., Remington's Pharmaceutical Sciences, 16th edition, A. Oslow, editor, Easton, Pa. (1980)). Drugs may be prepared in admixture with conventional excipients, carriers, buffers, flavoring agents, etc. Typical carriers include, but are not limited to: water; salt solutions; alcohols; gum arabic; vegetable oils; benzyl alcohols; polyethylene glycols; gelatin; carbohydrates, such as lactose, amylose or starch; magnesium stearate; talc; silicic acid; paraffin; perfume oil; fatty acid esters; hydroxymethylcellulose; polyvinyl pyrrolidone; etc. Pharmaceutical preparations can be sterilized and, if desired, mixed with auxiliary agents such as: lubricants; preservatives; disintegrants; stabilizers such as cyclodextrans; wetting agents; emulsifiers; salts; buffers; natural or artificial coloring agents; natural or artificial flavoring agents; or aromatic substances. Pharmaceutical preparations can also include one or more of the following: acetylated monoglyceride, aspartame, beta carotene, calcium stearate, carnauba wax, cellulose acetate phthalate, citric acid, citric acid anhydrous, colloidal silicon dioxide, confectioner's sugar, crospovidone, docusate sodium, ethyl alcohol, ferric oxide, fructose, gelatin, glycerine, glyceryl monostearate (e.g. glyceryl monostearate 40-50), glyceryl triacetate, HPMC (hydroxypropyl methylcellulose), hydroxypropyl cellulose, hypromellose, iron oxide, isopropyl alcohol, lactose monohydrate, low substituted hydroxypropyl cellulose, magnesium carbonate, magnesium stearate, maltol, mannitol, methacrylic acid, methacrylic acid copolymer (e.g. methacrylic acid copolymer type C), methylcellulose, microcrystalline cellulose, mono ammonium glycyrrhizinate, n-butyl alcohol, paraffin, pectin propylene glycol alginate, polyacrylate, polyethylene glycol (e.g. polyethylene glycol 6000), polysorbate 80, polyvinyl pyrrolidone, povidone, propylene glycol, shellac, silicon dioxide, sodium carbonate, sodium citrate, sodium hydroxide, sodium lauryl sulfate, sodium stearyl fumarate, sorbitol, starch, sucrose, sugar sphere, talc, titanium dioxide, triethyl citrate, and xanthan gum. In certain embodiments, buffers that can raise the pH of the stomach are used. For example bicarbonate buffers may be included in the outer coating or as a rapidly dissolving, separate layer immediately below the outer coating.
The enteric coating surrounding the core may be applied using standard coating techniques. Materials used to form the enteric coating may be dissolved or dispersed in organic or aqueous solvents and may include one or more of the following: methacrylic acid copolymers; shellac; hydroxypropylmethylcellulose phthalate; polyvinyl acetate phthalate; hydroxypropylmethylcellulose trimellitate; carboxymethylcellulo se; cellulose acetate phthalate; or other suitable enteric coating polymers. The pH at which the enteric coat will dissolve can be controlled by the polymer or combination of polymers selected and/or ratio of pendant groups. For example, dissolution characteristics of the coating can be altered by the ratio of free carboxyl groups to ester groups. Enteric coating layers may also contain pharmaceutical plasticizers such as: triethyl citrate; dibutyl phthalate; triacetin; polyethylene glycols; polysorbates; etc. Additives such as dispersants, colorants, anti-adhering and anti-foaming agents may also be included.
Making of Tablet Dosage Forms: Tablets can be made using standard technology well known in the art. Drugs used in the core or the outer coating may be granulated by methods such as slugging, low-shear or high-shear granulation, wet granulation, or fluidized bed granulation. Outer coatings may be formed by preparing a mixture containing appropriate polymers and a sufficient amount of drug to produce a therapeutically effective dose. The solution may then be sprayed on preformed, enterically-coated cores to produce the final tablets. If desired, a buffer layer or layer containing other agents may be interspersed between the enterically coated core and the outer coating.
In certain embodiments a pharmaceutical composition is prepared by adding a pharmaceutically acceptable carrier to the aforementioned compound, a pharmaceutically acceptable salt thereof, or a hydrate thereof as an active ingredient of the medicament of the present disclosure. As the medicament of the present disclosure, a substance, per se, that is selected from the group consisting of the alkylenedioxybenzene derivative and a pharmaceutically acceptable salt thereof, and a hydrate thereof and a solvate thereof may be administered to a mammal including human. In certain embodiments, pharmaceutical compositions comprising one or more of the aforementioned substances as an active ingredient and one or more of pharmaceutical additives are administered to a patient.
A variety of administration routes can be used in accordance with the present disclosure. An effective amount of the composition described herein can be administered parenterally, orally, by inhalation, nasally, buccally, or via an implanted reservoir. In certain embodiments the composition is administered orally. In certain embodiments oral sustained/extended release formulations are used.
Examples of the pharmaceutical composition include formulations for oral administration such as tablets, capsules, subtilized granules, powders, pills, troches, sublingual tablets and liquid preparations, and formulations for parenteral administration such as injections, suppositories, ointments, patches and the like.
In certain embodiments, formulations including those which slowly release the agent over time (i.e., sustained/extended release), such as found in lozenges, gums, and buccal patches are used. In other embodiments, formulations including agents in a bioadherent ingestible composition, such as those found in U.S. Pat. Nos. 5,858,391 and 5,670,163 to Cuca, et al. are used. The agent may also be formulated as a liquid or as a tablet, pill, capsule or powder to be dissolved in a liquid, and is preferably slowly sipped by the patient.
Tablets and capsules for oral administration are usually provided in a unit dosage form, and can be prepared by adding ordinary pharmaceutical carriers such as binders, fillers, diluents, compressing agents, lubricants, disintegrating agents, coloring matters, flavoring agents, and moistening agents. Tablets may be coated according to a well-known method, for example, by using an enteric coating agent. For example, fillers such as cellulose, mannitol and lactose; disintegrating agents such as starch, polyvinylpyrrolidone, starch derivatives and sodium starchglycolate; lubricants such as magnesium stearate; moistening agents such as sodium laurylsulfate and the like may be used.
Liquid preparations for oral administration can be provided in the forms of, for example, aqueous or oily suspensions, solutions, emulsions, syrups and elixirs, as well as dried formulations that are re-dissolvable before use by water or a suitable medium. Those liquid preparations may contain ordinary additives, for example, suspending agents such as sorbitol, syrups, methylcellulose, gelatin, hydroxyethylcellulose, carboxymethylcellulose, aluminum stearate gel and hydrogenated edible fats; emulsifiers such as lecitin, sorbitan monooleate and gum arabic; non-aqueous media including edible oils such as almond oil, rectified coconut oil, oily esters (e.g., esters of glycerin), propylene glycol and ethyl alcohol; preservatives such as methyl ester, ethyl ester and propyl ester of p-hydroxybenzoic acid and sorbic acid; and usual flavoring agents and coloring matters as required.
Formulations for oral administration can be manufactured according to a method well known in the art, for example, by mixing, filling, compressing and the like. In addition, it is also possible to disperse the active ingredient in a formulation containing a large amount of filler by repetitive mixing. Formulations for parenteral administration are generally provided as unit dosage form preparations containing the compound as the active ingredient and a sterilized medium. The solution for parenteral administration may generally be prepared by dissolving the compound in a medium, subjecting the resulting solution to filtration for sterilization, filling the solution in vials or ampoules, and sealing the vials or ampoules. It is also possible to freeze the composition and fill the result in vials, and then eliminate the moisture in vacuo to improve stability. Parenteral suspensions can be prepared by substantially the same method as that applied to solutions for parenteral administration; however, the suspensions can preferably be manufactured by suspending the active ingredient in a medium, and then subjecting the result to sterilization by using ethylene oxide or the like. Furthermore, surface active agents, moistening agents and so forth may also be added so that a uniform dispersion of the active ingredient can be obtained.
Combining two or more active ingredients in single dosage form results in the possibility of chemical interactions between the active drug substances. For example, acidic and basic active ingredients can react with each other and acidic active ingredients can facilitate the degradation of acid labile substances. Thus, in certain dosage forms, acidic and basic substances can be physically separated as two distinct or isolated layers in a compressed tablet, or in the core and shell of a press-coated tablet. Additional agents that are compatible with acidic as well as basic substances, have the flexibility of being placed in either layer. In certain multiple layer compositions at least one active ingredient can be enteric-coated. In certain embodiments thereof at least one active ingredient can be presented in a controlled release form. In certain embodiments where a combination of three or more active substances are used, they can be presented as physically isolated segments of a compressed mutlilayer tablet, which can be optionally film coated.
The therapeutic combinations described herein can be formulated as a tablet or capsule comprising a plurality of beads, granules, or pellets. All active ingredients including the vitamins of the combination are formulated into granules or beads or pellets that are further coated with a protective coat, an enteric coat, or a film coat to avoid the possible chemical interactions. Granulation and coating of granules or beads is done using techniques well known to a person skilled in the art. At least one active ingredient can present in a controlled release form. Finally these coated granules or beads are filled into hard gelatin capsules or compressed to form tablets.
The therapeutic combinations described herein can be formulated as a capsule comprising microtablets or minitablets of all active ingredients. Microtablets of the individual agents can be prepared using well known pharmaceutical procedures of tablet making like direct compression, dry granulation or wet granulation. Individual microtablets can be filled into hard gelatin capsules. A final dosage form may comprise one or more microtablets of each individual component. The microtablets may be film coated or enteric coated.
The therapeutic combinations described herein can be formulated as a capsule comprising one or more microtablets and powder, or one or more microtablets and granules or beads. In order to avoid interactions between drugs, some active ingredients of a said combination can be formulated as microtablets and the others filled into capsules as a powder, granules, or beads. The microtablets may be film coated or enteric coated. At least one active ingredient can be presented in controlled release form.
The therapeutic combinations described herein can be formulated wherein the active ingredients are distributed in the inner and outer phase of tablets. In an attempt to divide chemically incompatible components of proposed combination, few interacting components are converted in granules or beads using well-known pharmaceutical procedures in prior art. The prepared granules or beads (inner phase) are then mixed with outer phase comprising the remaining active ingredients and at least one pharmaceutically acceptable excipient. The mixture thus comprising inner and outer phase is compressed into tablets or molded into tablets. The granules or beads can be controlled release or immediate release beads or granules, and can further be coated using an enteric polymer in an aqueous or non-aqueous system, using methods and materials that are known in the art.
The therapeutic combinations described herein can be formulated as single dosage unit comprising suitable buffering agent. All powdered ingredients of said combination are mixed and a suitable quantity of one or more buffering agents is added to the blend to minimize possible interactions.
The agents described herein, alone or in combination, can be combined with any pharmaceutically acceptable carrier or medium. Thus, they can be combined with materials that do not produce an adverse, allergic or otherwise unwanted reaction when administered to a patient. The carriers or mediums used can include solvents, dispersants, coatings, absorption promoting agents, controlled release agents, and one or more inert excipients (which include starches, polyols, granulating agents, microcrystalline cellulose, diluents, lubricants, binders, disintegrating agents, and the like), etc. If desired, tablet dosages of the disclosed compositions may be coated by standard aqueous or nonaqueous techniques. The agents described herein, alone or in combination, can be formulated using Nanocrystal® technology (Elan Corporation, Dublin, Ireland).
The agents can be a free acid or base, or a pharmacologically acceptable salt thereof. Solids can be dissolved or dispersed immediately prior to administration or earlier. In some circumstances the preparations include a preservative to prevent the growth of microorganisms. The pharmaceutical forms suitable for injection can include sterile aqueous or organic solutions or dispersions which include, e.g., water, an alcohol, an organic solvent, an oil or other solvent or dispersant (e.g., glycerol, propylene glycol, polyethylene glycol, and vegetable oils). The formulations may contain antioxidants, buffers, bacteriostats, and solutes that render the formulation isotonic with the blood of the intended recipient, and aqueous and non-aqueous sterile suspensions that can include suspending agents, solubilizers, thickening agents, stabilizers, and preservatives. Pharmaceutical agents can be sterilized by filter sterilization or by other suitable means.
Suitable pharmaceutical compositions in accordance with the disclosure will generally include an amount of the active compound(s) with an acceptable pharmaceutical diluent or excipient, such as a sterile aqueous solution, to give a range of final concentrations, depending on the intended use. The techniques of preparation are generally well known in the art, as exemplified by Remington's Pharmaceutical Sciences, 18th Ed., Mack Publishing Company, 1995.
The agent can be in the form of a pharmaceutically acceptable salt. Such salts are prepared from pharmaceutically acceptable non-toxic bases including inorganic bases and organic bases. Examples of salts derived from inorganic bases include aluminum, ammonium, calcium, copper, ferric, ferrous, lithium, magnesium, manganic salts, manganous, potassium, sodium, zinc, and the like. In some embodiments, the salt can be an ammonium, calcium, magnesium, potassium, or sodium salt. Examples of salts derived from pharmaceutically acceptable organic non-toxic bases include salts of primary, secondary, and tertiary amines, benethamine, N,N′-dibenzylethylenediamine, diethylamine, 2-diethylaminoethanol, 2-dimethylaminoethanol, diethanolamine, ethanolamine, ethylenediamine, N-ethylmorpho line, N-ethylpiperidine, epolamine, glucamine, glucosamine, histidine, hydrabamine, isopropylamine, lysine, methylglucamine, meglumine, morpholine, piperazine, piperidine, polyamine resins, procaine, purines, theobromine, triethylamine, trimethylamine, tripropylamine, and trolamine, tromethamine. Examples of other salts include tris, arecoline, arginine, barium, betaine, bismuth, chloroprocaine, choline, clemizole, deanol, imidazole, and morpholineethanol.
The agents of the disclosure can be administered orally, e.g., as a tablet or cachet containing a predetermined amount of the active ingredient, pellet, gel, paste, syrup, bolus, electuary, slurry, capsule; powder; granules; as a solution or a suspension in an aqueous liquid or a non-aqueous liquid; as an oil-in-water liquid emulsion or a water-in-oil liquid emulsion, via a liposomal formulation (see, e.g., EP736299) or in some other form. Orally administered compositions can include binders, lubricants, inert diluents, lubricating, surface active or dispersing agents, flavoring agents, and humectants. Orally administered formulations such as tablets may optionally be coated or scored and may be formulated so as to provide sustained, delayed or controlled release of the active ingredient therein.
Doses of the aforementioned compounds as the active ingredient can be suitably decided depending on the purpose of administration, i.e., therapeutic or preventive treatment, nature of a disease to be treated or prevented, conditions, body weight, age, gender and the like of a patient. In the method for administering the pharmaceutical preparation according to the present disclosure, the fibric acid or statin derivative compositions may be administered simultaneously with a lipid altering agent or PDE inhibitor, or the two may be sequentially administered in an optional order. The practically desirable method and sequence for administration varies depending on the purpose of administration, i.e., therapeutic or preventive treatment, nature of a disease to be treated or prevented, conditions, body weight, age, gender and the like of a patient.

When administered in combination with a PDE inhibitor, about 1 mg to 100 mg of a PDE inhibitor per day for an adult can be orally administered (e.g., 25 mg, 50 mg, or 100 mg of sildenafil; 2.5 mg, 5 mg, 10 mg, or 20 mg of vardenafil; or 5 mg, 10 mg, or 20 mg of tadalafil). Such doses may be desirably administered once a day to several times a day as divided portions. For example, the compositions of the present disclosure may be administered at least 1×, 2×, 3×, 4×, 5×, 6×, 8×, 10× or 20× a day. In certain embodiments the composition described herein is administered at least once a day for a period of days, weeks, months or years. The agent may be administered at least once, twice, three, or four times daily. Depending upon the desired therapeutic action, patient response and other factors, the dosage form may be administered between meals, during meals, prior to a meal (i.e., within 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, or 60 minutes, 2 hours, 4 hours, 8 hours, or 12 hours prior to eating) or after a meal (i.e., within 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, or 60 minutes, 2 hours, 4, hours, 8 hours, or 12 hours following a meal). In certain embodiments the dosage unit and daily dose are equivalent. In various embodiments, the dosage unit is administered with food at anytime of the day, without food at anytime of the day, with food after an overnight fast (e.g. with breakfast), at bedtime after a low fat snack.
The compounds and pharmaceutical formulations described herein may be contained in a kit. The kit may include single or multiple doses of two or more agents, each packaged or formulated individually, or single or multiple doses of two or more agents packaged or formulated in combination. Thus, one or more agents can be present in first container, and the kit can optionally include one or more agents in a second or further container. The container or containers are placed within a package, and the package can optionally include administration or dosage instructions in the form of a label on the package or in the form of an insert included in the packaging of the kit. A kit can include additional components such as syringes or other means for administering the agents as well as diluents or other means for formulation.
Thus, the kits can comprise: a) a pharmaceutical composition comprising at least one fibric acid or statin derivative compound or composition described herein and at least one lipid altering agent and/or PDE inhibitor and a pharmaceutically acceptable carrier, vehicle or diluent; and b) a container or packaging. The kits may optionally comprise instructions describing a method of using the pharmaceutical compositions in one or more of the methods described herein (e.g., preventing or treating dyslipidemia, hyperlipidemia, hypercholesterolemia, hypertriglyceridemia, sitosterolemia, familial hypercholesterolemia, xanthoma, combined hyperlipidemia, lecithin cholesterol acyltransferase deficiency, tangier disease, abetalipoproteinemia, and fatty liver disease). The pharmaceutical composition comprising the at least one fibric acid or statin derivative compound or composition and at least one lipid altering agent and/or PDE inhibitor contained in the kit may be optionally combined in the same pharmaceutical composition.
A kit includes a container or packaging for containing the pharmaceutical compositions and may also include divided containers such as a divided bottle or a divided foil packet. The container can be, for example a paper or cardboard box, a glass or plastic bottle or jar, a re-sealable bag (for example, to hold a “refill” of tablets for placement into a different container), or a blister pack with individual doses for pressing out of the pack according to a therapeutic schedule. It is feasible that more than one container can be used together in a single package to market a single dosage form. For example, tablets may be contained in a bottle which is in turn contained within a box.
An example of a kit is a so-called blister pack. Blister packs are well known in the packaging industry and are being widely used for the packaging of pharmaceutical unit dosage forms (tablets, capsules, and the like). Blister packs generally consist of a sheet of relatively stiff material covered with a foil of a preferably transparent plastic material. During the packaging process, recesses are formed in the plastic foil. The recesses have the size and shape of individual tablets or capsules to be packed or may have the size and shape to accommodate multiple tablets and/or capsules to be packed. Next, the tablets or capsules are placed in the recesses accordingly and the sheet of relatively stiff material is sealed against the plastic foil at the face of the foil which is opposite from the direction in which the recesses were formed. As a result, the tablets or capsules are individually sealed or collectively sealed, as desired, in the recesses between the plastic foil and the sheet. Preferably the strength of the sheet is such that the tablets or capsules can be removed from the blister pack by manually applying pressure on the recesses whereby an opening is formed in the sheet at the place of the recess. The tablet or capsule can then be removed via said opening.
It may be desirable to provide a written memory aid containing information and/or instructions for the physician, pharmacist or subject regarding when the medication is to be taken. A “daily dose” can be a single tablet or capsule or several tablets or capsules to be taken on a given day. When the kit contains separate compositions, a daily dose of one or more compositions of the kit can consist of one tablet or capsule while a daily dose of another one or more compositions of the kit can consist of several tablets or capsules. A kit can take the form of a dispenser designed to dispense the daily doses one at a time in the order of their intended use. The dispenser can be equipped with a memory-aid, so as to further facilitate compliance with the regimen. An example of such a memory-aid is a mechanical counter that indicates the number of daily doses that have been dispensed. Another example of such a memory-aid is a battery-powered micro-chip memory coupled with a liquid crystal readout, or audible reminder signal which, for example, reads out the date that the last daily dose has been taken and/or reminds one when the next dose is to be taken.
