PHARMACEUTICAL COMPOSITIONS OF CETP INHIBITORS

Description

[0001] This invention pertains to compositions and methods for the treatment or prophylaxis of cardiovascular disorders comprising CETP inhibitors.

[0002] Hyperlipidemic conditions associated with elevated concentrations of total cholesterol and low-density lipoprotein (LDL) cholesterol are major risk factors for coronary heart disease, and atherosclerosis in particular. Additionally, numerous studies have demonstrated that a low plasma concentration of high-density lipoprotein (HDL) cholesterol is a powerful risk factor for the development of atherosclerosis.

[0003] Cholesteryl ester transfer protein (CETP) is a plasma protein that facilitates the movement of cholesteryl esters and triglycerides between various lipoproteins in the blood. The movement of cholesteryl ester from HDL to LDL by CETP has the effect of lowering HDL cholesterol and increasing LDL cholesterol. Inhibition of CETP activity by CETP inhibitors has been shown to effectively modify plasmid HDL/LDL ratios by elevating plasma HDL cholesterol and lowering plasma LDL cholesterol.

[0004] To be effective, CETP inhibitors must be absorbed into the blood. Oral dosing of CETP inhibitors is preferred because to be effective such CETP inhibitors must be taken on a regular basis, such as daily. CETP inhibitors, particularly those that have high binding activity, are generally hydrophobic, have extremely low aqueous solubility, and have low oral bioavailability when dosed conventionally. Such compounds have generally proven to be difficult to formulate for oral administration such that high bioavailabilities are achieved.

[0005] International Patent Application WO 02/11710 recognizes this problem of low bioavailability and attempts to solve such a problem by formulating a composition comprising a solid dispersion of a CETP inhibitor in an amorphous form and a watersoluble polymer that increases the concentration of the CETP inhibitor in the environment of use. However; as many CETP inhibitors are in crystalline form, there is an ongoing need for improved compositions of crystalline CETP inhibitors.

[0006] Therefore, there remains a need for pharmaceutical compositions comprising CETP inhibitors in crystalline form that result in increased bioavailability of the CETP inhibitors in the environment of use. The invention provides such a pharmaceutical composition and methods of treating cardiovascular disorders using the pharmaceutical compositions. These and other advantages of the invention, as well as additional inventive features, will be apparent from the description of the invention provided herein.

[0007] The invention provides a pharmaceutical composition comprising the cholesteryl ester transfer protein inhibitor S-[2-([[1-(2-ethylbutyl)cyclohexyl]carbonyl]amino)phenyl] 2-methylpropanethioate and crospovidone as a water-insoluble concentration-enhancing additive.

[0008] The invention also provides the use of this composition for treating or preventing a cardiovascular disorder in a mammal by administering to a mammal in need of such treatment a therapeutically effective amount of the pharmaceutical composition provided by the invention.

Figure 5 is a plot of mean CETP activities and mean plasma concentrations of the active form of S-[2-([(1-(2-ethylbutyl)cyclohexyl]carbonyl]amino)phenyl]2-methylpropanethioate over 24 hours in Caucasian male patients following the oral administration of 900 mg of S-[2-([[1-(2-ethylbutyl)cyclohexyl]carbonyl]amino)phenyl] 2-methylpropanethioate without food.

[0009] The CETP inhibitor is S-[2-([[1-(2-ethylbutyl)cyclohexyl]carbonyl]amino)phenyl] 2-methylpropanethioate (which also is known as propanethioic acid, 2-methyl-, S-[2-[[[1-(2-ethylbutyl)cyclohexyl]carbonyl]amino]phenyl]ester; S-[2-[1-(2-ethylbutyl)cyclohexanecarbonylamino]phenyl] 2-methylthiopropionate, or JTT-705) (herein referred to as Compound I). Compound I has the following structural formula:

[0010] S-[2-([[1-(2-ethylbutyl)cyclohexyl]carbonyl]amino]phenyl] 2-methylpropanethioate has been shown to be an inhibitor of CETP activity in humans (de Grooth et al., Circulation, 105, 2159-2165 (2002)) and rabbits (Shinkai et al., J. Med. Chem., 43, 3566-3572 (2000); Kobayashi et al., Atherosclerosis, 162, 131-135 (2002); and Okamoto et al., Nature, 406(13), 203-207 (2000)). S-[2-([[1-(2-ethylbutyl)cyclohexyl]carbonyl]amino)phenyl] 2-methylpropanethioate has been shown to increase plasma HDL cholesterol in humans (de Grooth et al., supra) and in rabbits (Shinkai et al., supra; Kobayashi et al., supra; Okamoto et al., supra). Moreover, S-[2-([[1-(2-ethylbutyl)cyclohexyl]carbonyl]amino)phenyl] 2-methylpropanethioate has been shown to decrease LDL cholesterol in humans (de Grooth et al., supra) and rabbits (Okamoto et al., supra). Additionally, S-[2-([[1-(2-ethylbutyl)cyclohexyl)carbonyl)amino)phenyl] 2-methylpropanethioate inhibits the progression of atherosclerosis in rabbits (Okamoto et al., supra). S-[2-([[1-(2-ethylbutyl)cyclohexyl]carbonyl]amino)phenyl] 2-methylpropanethioate, as well as methods of making and using the compound, are described in U.S. Patent 6,426,365.

[0011] While not wishing to be bound by any particular theory, it is hypothesized that within the body of a patient, Compound I is hydrolyzed in plasma, the liver, and/or the small intestine to form S-[2([[1-(2-ethylbutyl)cyclohexyl]carbonyl]amino)phenyl] thiol (herein referred to as Compound II). It is known that low molecular weight thiol components (i.e., R-SH), such as cysteine and glutathione, and high molecular weight thiol components (i.e., Prot-SH), such as peptides and proteins (e.g., enzymes and cell membranes), exist in the body as mixed disulfides containing an oxidized disulfide bond (S-S bond) between or within the molecule (see, e.g., Shimade et al., J. Chromatogr. B, 659, 227 (1994)). Therefore, it is hypothesized that within the body of a patient, Compound II is conjugated with low or high molecular weight thiols to yield mixed disulfides or to yield dimers of Compound II. Since these forms are in an oxidation-reduction equilibrium with each other via Compound II, all of these forms, as well as Compound II, are collectively, but not exclusively, considered and referred to hereafter as the active form of Compound I. The following scheme depicts the above-described hypothesis.

[0012] While the administration of Compound I is a particularly preferred embodiment of the invention, the invention also contemplates the administration of other compounds that will yield the active form of Compound I, i.e., other prodrugs of the active form of Compound I. Such prodrugs, for example, can be compounds that have different mercapto-protecting groups, but that still result in the formation of the active form of Compound I (e.g., Compound II) in the body of a patient (i.e., in vivo). The term "mercapto-protecting groups" refers to commonly used mercapto-protecting groups (e.g., as described in Wolman, The Chemistry of the Thiol Group, D. Patai, Ed., Wiley-Interscience, New York, 1974). Any organic residues that can be dissociated in vivo may be used without particular restriction. Examples of particularly suitable mercapto-protecting groups are described in U.S. Patent 6,426,365. The invention further contemplates the administration of Compound I' (wherein R' signifies an organic residue other than an isopropyl group) so as to yield the active form of Compound I.

[0013] In addition, Compounds III, IV, and V (wherein R signifies an organic residue and Prot signifies a peptide or protein), which are believed to be in equilibrium with Compound II in vivo, similarly can be directly administered to the patient.

[0014] The CETP inhibitor can be in any suitable form (e.g., as a solid or a liquid, in crystalline or amorphous form, or any combination thereof). In a preferred embodiment, the CETP inhibitor is a solid in crystalline or amorphous form. The term "amorphous" signifies a non-crystalline state. The term "combination thereof" as applied to the amorphous or crystalline states of the CETP inhibitor refers to a mixture of amorphous and crystalline forms of the CETP inhibitor. A major portion of the CETP inhibitor can be in amorphous or crystalline form. As used herein, the term "a major portion" of the CETP inhibitor means more than 50% of the CETP inhibitor in the composition. For example, a major portion of the CETP inhibitor in the composition can be in crystalline form. Alternatively, the CETP inhibitor in the composition can be "substantially amorphous" (i.e., the amount of the CETP inhibitor in crystalline form does not exceed about 10%) or "substantially crystalline" (i.e., the amount of the CETP inhibitor in amorphous form does not exceed about 10%). Preferably, the CETP inhibitor is at least about 50% (e.g., at least about 55%, at least about 60%, at least about 65%, at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 95%, or actually about 100%) crystalline. The amount of crystalline CETP inhibitor can be measured by powder X-ray diffraction, Scanning Electron Microscope (SEM) analysis, differential scanning calorimetry (DSC), or any other standard quantitative measurement.

[0015] A substantial number of CETP inhibitors have a low aqueous solubility, a low bioavailability, and/or a slow rate of absorption such that it is desirable to increase their concentration in an aqueous environment of use. As used herein, the term "bioavailability" generally means the rate and extent to which the active ingredient, or active form thereof, is absorbed from a drug product and becomes available at the site of action. See U.S. Code of Federal Regulations, Title 21, Part 320.1 (2001 ed.). For oral dosage forms, bioavailability relates to the processes by which the active ingredient is released from the oral dosage form, e.g., a tablet, converted to the active form (if the active ingredient is not already the active form), and moved to the site of action, e.g., absorbed into the systemic circulation.

[0016] Oral delivery of many CETP inhibitors is often difficult because the aqueous solubility of CETP inhibitors is extremely low (i.e., the CETP inhibitor is substantially water-insoluble). The terms "extremely low aqueous solubility" and "substantially water-insoluble" signify that the CETP inhibitor has a maximum aqueous solubility of less than about 10 µg/mL (e.g., less than about 5 µg/mL, less than about 2 µg/mL, less than about 1 µg/mL, less than about 0.5 µg/mL, less than about 0.1 µg/mL, less than about 50 ng/mL, less than about 20 ng/mL, or less than about 10 ng/mL) at any physiologically relevant pH (e.g., pH 1-8) and at about 22° C. For example, the solubility of Compound I in water is less than about 0.0001 mg/mL. Such low solubilities are a direct consequence of the particular structural characteristics of the species that bind to CETP, and thus act as CETP inhibitors. This low solubility is primarily due to the hydrophobic nature of CETP inhibitors.

[0017] Thus, the hydrophobic and insoluble nature of CETP inhibitors poses a particular challenge for oral delivery. Achieving therapeutic drug levels in the blood by oral dosing of practical quantities of drug generally requires a large enhancement in drug concentrations in the gastrointestinal fluid and a resulting large enhancement in bioavailability. Additionally, the CETP inhibitors can have a very high dose-to-solubility ratio. Extremely low solubility often leads to poor or slow absorption of the drug from the fluid of the gastrointestinal tract, when the drug is dosed orally in a conventional manner. For extremely low solubility drugs, poor absorption generally becomes progressively more difficult as the dose (mass of drug given orally) increases.

[0018] The CETP inhibitors are characterized by a low melting point The CETP inhibitors preferably have a melting point of about 150° C or less (e.g., about 140° C or less, about 130° C or less, about 120° C or less, about 110° C or less, about 100° C or less, about 90° C or less, about 80° C or less, or about 70° C or less. For example, Compound I has a melting point of about 63-65° C.

[0019] As a consequence of one or more of these properties, CETP inhibitors typically have very low absolute bioavailabilities. Specifically, the absolute bioavailability of CETP inhibitors when dosed orally in their undispersed state is less than about 10% (e.g., less than about 9%, less than about 8%, less than about 7%, or less than about 6%) and more often less than about 5% (e.g., less than about 4%, less than about 3%, less than about 2%, or less than about 1%).

[0020] To overcome the very low absolute bioavailabilities associated with CETP inhibitors, the invention provides a pharmaceutical composition comprising a CETP inhibitor as defined above and a water-insoluble concentration-enhancing additive, wherein the water-insoluble concentration-enhancing additive is crospovidone (i.e., a synthetic homopolymer of cross-linked N-vinyl-2-pyrrolidone). Advantageously, it has been found that inclusion of the water-insoluble concentration-enhancing additive dramatically improves the bioavailability of the CETP inhibitor.

[0021] By "water-insoluble" additive it is meant that the additive has a maximum aqueous solubility of less than about 10 µg/mL at any physiologically relevant pH (e.g., pH 1-8) and at about 22° C. By "concentration-enhancing additive(s)" it is meant that the additive enhances the bioavailability of the CETP inhibitor relative to the administration of the CETP inhibitor in the absence of the concentration-enhancing additive(s). For example, the presence of an additive in the pharmaceutical composition preferably enhances the concentration of the CETP inhibitor (or active form thereof) in the aqueous environment of use (e.g., plasma, especially of a human) when compared to the administration of the CETP inhibitor in the absence of the additive. Thus, the additive can be considered a "concentration-enhancing additive" or, when such an additive is a polymer, a "concentration-enhancing polymer."

[0022] The pharmaceutical composition comprising a CETP inhibitor and a water-insoluble concentration-enhancing additive is capable of achieving specific maximum concentrations and areas under the concentration-time curve (AUC) from time zero up to the last quantifiable concentration (0-t_z) and/or from time zero to infinity (0-∞) of the active form of the CETP inhibitor (e.g., the active form of Compound I) in the environment of use (typically plasma, especially of a human), as discussed further in the description of the methods of use of the pharmaceutical compositions.

[0023] The amount of water-insoluble concentration-enhancing additive relative to the amount of CETP inhibitor present in the Pharmaceutical composition depends on the CETP inhibitor and concentration-enhancing additive. The weight ratio of CETP inhibitor to additive can be from about 1:100 to about 10:1 (e.g., about 1:50, about 1:25, about 1:10, about 1:5, about 1:4; about 1:3, about 1:2, about 1:1, about 2:1, about 3:1, about 4:1, about 5:1, about 6:1, about 7:1, about 8:1, about 9:1, or ranges thereof). Preferably, the CETP inhibitor to additive weight ratio is about 2:1 to about 9:1, more preferably about 2:1 to about 4:1. The CETP inhibitor to additive ratio that yields optimum results varies from CETP inhibitor to CETP inhibitor and is best determined in in vitro dissolution tests and/or in vivo bioavailability tests.

[0024] Crospovidone can be present in the pharmaceutical composition in any suitable amount, desirably within the range of about 30% to about 100% (e.g., about 40%, about 50%, about 60%, about 70%, about 80%, about 90%, or ranges thereof) by weight of the CETP inhibitor (e.g., Compound I). In a preferred embodiment of the present invention, the weight ratio of CETP inhibitor to crospovidone can be from about 1:1 to about 3.3:1, more preferably about 2:1 to about 3:1. The amount of crospovidone in the pharmaceutical composition is important for disintegration and dissolution of the dosage form (e.g., tablet). For example, when the pharmaceutical composition comprises less than about 30% (e.g., less than about 25%, less than about 20%, less than about 15%, less than about 10%, or less than about 5%) of the CETP inhibitor by weight, the disintegration time of the tablet is delayed, and the resulting dissolved amount of the CETP inhibitor is decreased. The disintegration time and resulting dissolution amount are closely related to the absorbable amount of the CETP inhibitor in the gastrointestinal tract, which affects the efficacy level of the pharmaceutical composition.

[0025] The pharmaceutical composition comprising a CETP inhibitor and a water-insoluble concentration-enhancing additive (crospovidone) also can comprise one or more pharmacologically acceptable additives, such as pharmaceutically acceptable carriers or excipients and optionally other therapeutic agents (e.g., hydroxy-methylglutaryl coenzyme A reductase inhibitors) and/or components. For example, the CETP inhibit or can be used together with known pharmacologically acceptable carriers, excipients, diluents, extenders, disintegrants, stabililizers, preservatives, buffers, emulsifiers, aromatics, colorants, sweeteners, viscosity increasing agents, flavor improving agents, solubilizers, and other additives. These additives must be acceptable in the sense of being compatible with the other ingredients and not deleterious to the recipient thereof. Examples of additives for oral administration include cornstarch, lactose, magnesium stearate, talc, microcrystalline cellulose, stearic acid, povidone, dibasic calcium phosphate, sodium starch glycolate, hydroxypropyl cellulose (e.g., low substituted hydroxypropyl cellulose), hydroxypropylmethyl cellulose (e.g., hydroxypropylmethyl cellulose 2910), and sodium lauryl sulfate.

[0026] The pharmaceutical composition desirably is in the form of a mixture, preferably a solid mixture, which is prepared by mechanically mixing the CETP inhibitor and water-insoluble concentration-enhancing additive, as well as additional pharmacologically acceptable additives. The composition is preferably substantially homogeneous so that the CETP inhibitor is dispersed as homogeneously as possible throughout the composition. As used herein, "substantially homogeneous" means that the fraction of CETP inhibitor that is present in relatively pure domains within the composition is relatively small, for example, less than about 20%, less than about 15%, less that about 10%, or less than about 5% of the total amount of CETP inhibitor.

[0027] The preferred solid composition may have one or multiple glass transition temperatures (T_gs). In one embodiment, the solid composition has a single glass transition temperature, which demonstrates that the composition is substantially homogeneous. T_g as used herein is the characteristic temperature where a glassy material, upon gradual heating, undergoes a relatively rapid (e.g., about 10 to about 100 seconds) physical change from a glass state to a rubber state. The T_g of a material can be measured by several techniques, including by a dynamic mechanical analyzer (DMA), a dilatometer, dielectric analyzer, and by a differential scanning calorimeter (DSC). The exact values measured by each technique can vary somewhat but usually fall within 10° C to 30° C of each other. Regardless of the technique used, when a composition exhibits a single T_g, this indicates that the composition is substantially homogenous.

[0028] The pharmaceutical composition can be prepared by any suitable method, such as those methods well known in the art of pharmacy, for example, methods such as those described in Gennaro et al., Remington's Pharmaceutical Sciences (18th ed., Mack Publishing Co., 1990), especially Part 8: Pharmaceutical Preparations and their Manufacture. Such methods include the step of bringing into association the CETP inhibitor with the other components of the pharmaceutical composition.

[0029] The pharmaceutical composition comprising the CETP inhibitor and water-insoluble concentration-enhancing additive can be made according to any suitable process. Preferably, the manufacturing process includes mechanical processes such as milling and extrusion. Alternatively, the pharmaceutical composition can be prepared by melt processes, such as high temperature fusion, solvent modified fusion, and melt-congeal processes; or solvent processes, such as non-solvent precipitation, spray coating, and spray-drying.

[0030] The pharmaceutical composition can provide controlled, slow release, or sustained release of the CETP inhibitor over a predetermined period of time. The controlled, slow release, or sustained release of the therapeutic compound can provide for a concentration of the CETP inhibitor, or the active form thereof, to be maintained in the bloodstream of the patient for a longer period of time. Such a pharmaceutical composition includes coated tablets, pellets, and capsules. Alternatively, the pharmaceutical composition can be in the form of a dispersion of the therapeutic compound in a medium that is insoluble in physiologic fluids or where the release of the therapeutic compound follows degradation of the pharmaceutical composition due to mechanical, chemical, or enzymatic activity.

[0031] The pharmaceutical composition can be, for example, in the form of a pill, capsule, or tablet, each containing a predetermined amount of the CETP inhibitor and preferably coated for ease of swallowing, in the form of a powder or granules. Preferably, the pharmaceutical composition is in the form of a tablet comprising the CETP inhibitor and the components of the tablet utilized and described in the Examples herein. For oral administration, fine powders or granules may contain diluting, dispersing, and or surface active agents and may be present, for example, in capsules or sachets in the dry state, or in tablets wherein binders and lubricants may be included. Components such as sweeteners, flavoring agents, preservatives (e.g., antimicrobial preservatives), suspending agents, thickening agents, and/or emulsifying agents also may be present in the pharmaceutical composition. A component of the formulation may serve more than one function.

[0032] Oral delivery methods are often limited by chemical and physical barriers imposed by the body, such as the varying pH in the gastrointestinal tract, exposure to enzymes, and the impermeability of the gastrointestinal membranes. The oral administration of the pharmaceutical composition may also include the co-administration of adjuvants. For example, nonionic surfactants such as polyoxyethylene oleyl ether and n-hexadecyl polyethylene ether can be administered with or incorporated into the pharmaceutical composition to artificially increase the permeability of the intestinal walls. Enzymatic inhibitors also can be administered with or incorporated into the pharmaceutical composition.

[0033] The pharmaceutical composition can be administered in any suitable manner. Preferably, the composition is administered with food. The term "with food" is defined to mean, in general, the condition of having consumed food during the period between from about 1 hour prior to the administration of the pharmaceutical composition comprising the CETP inhibitor to about 2 hours after the administration of the composition. Preferably, the food is a solid food with sufficient bulk and fat content that it is not rapidly dissolved and absorbed in the stomach. More preferably, the food is a meal, such as breakfast, lunch, or dinner.

[0034] Advantageously, the pharmaceutical composition is administered any time of day with food. The food can be consumed at any time during the period between from about 1 hour prior to the administration of the composition to about 2 hours after the administration of the composition. For example, the food can be consumed within the time period of about 1 hour, about 45 minutes, about 30 minutes, about 15 minutes, about 10 minutes, or about 5 minutes prior to the administration of the composition. Similarly, the food can be consumed within the time period of about 5 minutes, about 10 minutes, about 15 minutes, about 30 minutes, about 45 minutes, about 1 hour, about 1.25 hours, about 1.5 hours, about 1.75 hours, or about 2 hours after the administration of the composition. More preferably, the administration of the composition to the patient is immediately after the consumption of food (e.g. within about I minute after food consumption) up to about 1 hour after food consumption. Ideally, the pharmaceutical composition comprising the CETP inhibitor is administered at substantially the same time as the consumption of the food. The administration of the pharmaceutical composition with food can increase the bioavailability of the CETP inhibitor in the aqueous environment of use.

[0035] The terms "without food" or "fasted" are defined to mean the condition of not having consumed food within the time period of about 1 hour prior to the administration of the composition to about 2 hours after the administration of the composition.

[0036] The pharmaceutical composition can be used to treat or prevent a cardiovascular disorder, including, but not limited to, atherosclerosis, peripheral vascular disease, dyslipidemia (e.g., hyperlipidimia), hyperbetalipoproteinemia, hypoalphalipoproteinemia, hypercholesterolemia, hypertriglyceridemia, familial-hypercholesterolemia, angina, ischemia, cardiac ischemia, stroke, myocardial infarction, reperfusion injury, angioplastic restenosis, hypertension, cardiovascular disease, coronary heart disease, coronary artery disease, hyperlipidoproteinemia, vascular complications of diabetes, obesity or endotoxemia in a mammal, especially a human (i.e., a male or female human).

[0037] Accordingly, the invention provides {--} for the treatment or prophylaxis of a cardiovascular disorder in a mammal (preferably a mammal in need thereof) a therapeutically effective amount of the pharmaceutical composition. The mammal preferably is a human (i.e., a male or female human). The human can be of any race (e.g., Caucasian or Oriental). The cardiovascular disorder preferably is selected from the group consisting of atherosclerosis, peripheral vascular disease, dyslipidemia, hyperbetalipoproteinemia, hypoalphalipoproteinemia, hypercholesterolemia, hypertriglyceridemia, familial-hypercholesterolemia, angina, ischemia, cardiac ischemia, stroke, myocardial infarction, reperfusion injury, angioplastic restenosis, hypertension, and vascular complications of diabetes, obesity or endotoxemia in a mammal. More preferably, the cardiovascular disorder is selected from the group consisting of cardiovascular disease, coronary heart disease, coronary artery disease, hypoalphalipoproteinemia, hyperbetalipoproteinemia, hypercholesterolemia, hyperlipidemia, atherosclerosis, hypertension, hypertriglyceridemia, hyperlipidoproteinemia, peripheral vascular disease, angina, ischemia, and myocardial infarction.

[0038] The CETP inhibitor can be administered to the mammal at any suitable dosage (e.g., to achieve a therapeutically effective amount). For example, a suitable dose of a therapeutically effective amount of Compound I for administration to a patient will be between approximately 100 mg to about 1800 mg per day. A desirable dose is preferably about 300 mg to about 900 mg per day. A preferred dose is about 600 mg per day. The pharmacokinetics parameters (e.g., area under the concentration-time curve, maximum concentration, and the like) will, of course, vary based on the dosage administered to the mammal (e.g., human). The pharmacokinetics parameters may also be-influenced by additional factors, such as the mass of the mammal and genetic components. For example, as illustrated by Examples 1-4, the bioavailability of Compound I (as indicated by C_max, AUC_0-tz, and AUC_0-∞) is greater following administration to Oriental (especially Japanese) humans as compared to Caucasian humans.

[0039] If desired, the effective daily dose of the CETP inhibitor (e.g., Compound I) may be administered as two, three, four, five, six, or more sub-doses administered separately at appropriate intervals throughout the day, optionally, in unit dosage forms. Each such sub-dose contains a therapeutically effective amount of the CETP inhibitor (e.g., Compound I).

[0040] The pharmaceutical composition, when administered to a mammal, especially a human, desirably achieves certain pharmacokmetic effects as evaluated by the maximum observed plasma concentration of the active form of CETP inhibitor (e.g., the active form of Compound I) (C_max), the area under the plasma concentration-time curve (AUC) from time zero up to the last quantifiable concentration (0-t_z) and/or from time zero to infinity (0-∞) of the CETP inhibitor (e.g., the active form of Compound 1), and/or a decrease in CETP activity (as compared to CETP activity before administration of the pharmaceutical composition).

[0041] The pharmaceutical composition, at a daily dose of 300 mg, 600 mg, or 900 mg of the CETP inhibitor, particularly Compound I, administered with food, preferably achieves a C_max, AUC_0-tz, AUC_0-∞, and/or decrease in CETP activity in the environment of use (e.g., plasma, especially of a human), as set forth below:

[0042] C_max (300 mg daily dose): at least about 0.1 µg/mL (e.g., at least about 0.15 µg/mL, at least about 0.2 µg/mL, at least about 0.25 µg/mL, at least about 0.3 µg/ml, at least about 0.4 µg/mL, at least about 0.5 µg/mL, at least about 0.6 µg/mL, at least about 0.7 µg/mL, at least about 0.8 µg/mL, at least about 0.9 µg/mL, at least about 1 µg/mL, at least about 1.1 µg/mL, at least about 1.2 µg/mL, at least about 1.3 µg/mL, at least about 1.4 µg/mL, at least about 1.5 µg/mL, at least about 1.6 µg/mL, at least about 1.7 µg/mL, or at least about 1.8 µg/mL).

[0065] Decrease in CETP activity (600 mg daily dose): at least about 5% (e.g., at least about 7.5%, at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45%, at least about 50%, at least about 55%, or at least about 60% or more) relative to the CETP activity before administration of the pharmaceutical composition.

[0067] Furthermore, the pharmaceutical composition of the invention, when administered to a patient, desirably results in one or more (e.g., two or three) of the following conditions in the patient: (a) an inhibition of cholesteryl ester transfer protein (CETP) activity in the patient relative to pretreatment CETP activity (as described above), (b) an increase in high density lipoprotein cholesterol (HDL-C) level in the patient relative to pretreatment HDL-C level, and (c) a decrease in the ratio of total cholesterol to HDL-C level (TC/HDL-C) in the patient relative to pretreatment TC/HDL-C. The term "pretreatment" refers to the time prior (desirably immediately prior) to administration of the active compounds of the composition of the invention to the patient. The desired extent of changes in each of the foregoing conditions in the patient relative to pretreatment are recited below.

[0068] The HDL-C level is measured using standard techniques known in the art. Preferably, the HDL-C level following the administration (e.g. after 4 weeks of treatment) of 300 mg of the CETP inhibitor, particularly Compound I, is increased by about 10% or more relative to pretreatment HDL-C level (e.g., about 12.5% or more, about 15% or more, about 17.5% or more, about 20% or more, about 22.5% or more, about 25% or more, about 27.5% or more, about 30% or more, about 32.5% or more, about 35% or more, about 37.5% or more, about 40% or more, about 42.5% or more, about 45% or more, about 47.5% or more, or about 50% or more).

[0069] The HDL-C level following the administration (e.g. after 4 weeks of treatment) of 600 mg of the CETP inhibitor, particularly Compound I, is increased by about 15% or more relative to pretreatment HDL-C level (e.g., about 17.5% or more, about 20% or more, about 22.5% or more, about 25% or more, about 27.5% or more, about 30% or more, about 32.5% or more, about 35% or more, about 37.5% or more, about 40% or more, about 42.5% or more, about 45% or more, about 47.5% or more, about 50% or more, about 52.5% or more, or about 55% or more).

[0070] The HDL-C level following the administration (e.g. after 4 weeks of treatment) of 900 mg of the CETP inhibitor, particularly Compound I, is preferably increased by about 20% relative to pretreatment HDL-C level (e.g., about 22.5% or more, about 25% or more, about 27.5% or more, about 30% or more, about 32.5% or more, about 35% or more, about 37.5% or more, about 40% or more, about 42.5% or more, about 45% or more, about 47.5% or more, about 50% or more, about 52.5% or more, about 55% or more, about 57.5% or more, or about 60% or more).

[0071] Total cholesterol (TC) is determined using standard techniques known in the art. Preferably, the TC/HDL-C ratio following the administration (e.g. after 4 weeks of treatment) of 300 mg of the CETP inhibitor, particularly Compound I, is decreased by about 5% or more relative to the pretreatment TC/HDL-C ratio (e.g., about 7.5% or more, about 10% or more, about 12.5% or more, about 15% or more, about 17.5% or more, about 20% or more, about 22.5% or more, about 25% or more, about 27.5% or more, about 30% or more, about 32.5% or more, or about 35% or more).

[0072] The TC/HDL-C ratio following the administration (e.g. after 4 weeks of treatment) of 600 mg of the CETP inhibitor, particularly Compound I, is decreased by about 10% or more relative to the pretreatment TC/HDL-C ratio (e.g., about 12.5% or more, about 15% or more, about 17.5% or more, about 20% or more, about 22.5% or more, about 25% or more, about 27.5% or more, about 30% or more, about 32.5% or more, about 35% or more, or about 37.5% or more, or about 40% or more).

[0073] The TC/HDL-C ratio following the administration (e.g. after 4 weeks of treatment) of 900 mg of the CETP inhibitor, particularly Compound I, is decreased by about 15% or more relative to the pretreatment TC/HDL-C ratio (e.g., about 17.5% or more, about 20% or more, about 22.5% or more, about 25% or more, about 27.5% or more, about 30% or more, about 32.5% or more, about 35% or more, or about 37.5% or more, about 40% or more, about 42.4% or more, or about 45% or more).

[0074] Moreover, the invention provides a kit comprising a pharmaceutical composition comprising a therapeutically effective amount of a CETP inhibitor (e.g., Compound I) and a water-insoluble concentration-enhancing additive, prescribing information, and a container. The prescribing information can be prescribing information conforming to the methods of the invention and/or as otherwise discussed herein. The prescribing information preferably includes advice to a patient regarding the administration of the CETP inhibitor (e.g., Compound I) with food, especially to improve the bioavailability of the CETP inhibitor.

[0075] The following examples further illustrate the invention but, of course, should not be construed as in any way limiting its scope.

EXAMPLE 1

[0076] This example illustrates the absorption of a CETP inhibitor (e.g., Compound I) when administered in a pharmaceutical composition according to the invention.

[0077] For this study, Caucasian male human subjects were administered 100 mg, 300 mg, 600 mg, 900 mg, 1200 mg, 1500 mg, or 1800 mg of Compound I, or placebo, after a standard breakfast The tablets administered at each dose level are recited in Table 1.

Table 1- Tablets Administered at Each Dose Level

Dose Level (mg)	Number of Tablets Administered per Subject

[0078] The uncoated white tablets were prepared using standard tableting procedures. The 100 mg tablets comprised 100 mg of Compound I, 6 mg of hydroxypropylmethyl cellulose 2910 as a binder, 175.1 mg of microcrystalline cellulose and 116.8 mg of lactose as diluents, 18 mg talc and 1.2 mg of magnesium stearate as lubricants, and 39.9 mg of crospovidone and 90 mg of low substituted hydroxypropyl cellulose as disintegrants.

[0079] The 300 mg tablets comprised 300 mg of Compound I, 18 mg of hydroxypropylmethyl cellulose 2910 as a binder, 18 mg of talc and 1.2 mg of magnesium stearate as lubricants, and 119.8 mg of crospovidone and 90 mg of low substituted hydroxypropyl cellulose as disintegrants.

[0080] The placebo tablets comprised 175.1 mg of microcrystalline cellulose and 262.7 mg of lactose as diluents, 18 mg oftalc and 1.2 mg of magnesium stearate as lubricants, and 90 mg of low substituted hydroxypropyl cellulose as a disintegrant The placebo tablets were similar in appearance to the tablets comprising Compound I.

[0081] Treatments were administered orally with 150 mL water while standing. Subjects were not allowed to lie supine for 2 hours after dose administration, except for study procedures.

[0082] Doses were administered at similar times for each subject in each treatment period. Dosing commenced at approximately 08:30 hours. All subjects fasted from food and fluids (with the exception of water) from 22:00 hours on the day prior to dosing (Day - 1) until breakfast on Day 1, and during the evening prior to the post-study visit until laboratory safety evaluations had been performed on the following day. Water could be consumed at any time during the study, with the exception of the period up to 2 hours post-dose, when no fluids were permitted.

[0083] Subjects received a standard breakfast about 45 minutes prior to dosing. The meal was eaten at a steady rate over a 15 minute period so that the meal was completed 30 minutes before dosing. The standard breakfast consisted of the following:

200 mL orange juice

Two packets of cereal (approximately 60 g)

Two slices of wholemeal toast

10 g low fat spread (one packet)

20 gjam (one packet)

242 mL full fat milk (approximately 250 g)

Total energy content:	711 Kcal
Total fat content:	15.72 g (19.9% of total calories)
Total protein:	20.82 g (11.7% total calories)

[0084] Blood samples for pharmacokinetic analysis were taken immediately prior to dosing and at the following times after dosing: 1,2,4,6, 7, 10, 12, 24, and 36 hours post-dose.

[0085] The following pharmacokinetic parameters were calculated for the different dosage profiles and are defined as follows:

t_max

Time of maximum observed plasma concentration of the active form of Compound I;

C_max

Maximum observed plasma concentration of the active form of Compound I;

t_1/2

Half-life of plasma concentration of the active form of Compound I;

AUC_0-tz

Area under the plasma concentration-time curve (AUC) from time zero up to the last quantifiable concentration (0-t_z), of the active form of Compound I; and

AUC_0-∞

AUC from time zero to infinity (0-∞)

[0086] Pharmacokinetic parameters were log-transformed by analysis and assessed using SAS® Least Square Means derived from a three-way analysis of variance (ANOVA) fitting effects for subject, treatment, and period. Treatment comparisons were made by calculating the difference and 95% confidence intervals (CIs) of the difference of the log SAS® Least Square Means between parameters for the respective treatments. The differences and CIs of the differences were back-transformed for reporting purposes.

[0087] The plasma concentration of the active form of Compound I was determined by the following assay. Plasma samples were isolated from patients treated with Compound I. The plasma samples were treated with sodium hydroxide (Wako Pure Chemical Industries, Ltd.) to convert active forms of Compound I in the plasma to the thiol form (i.e., Compound II). The plasma sample next was treated with dithiothreitol (DTT) (Wako Pure Chemical Industries, Ltd.) to prevent the oxidation of thiol groups (i.e., to maintain thiol groups in a reduced state). N-ethylmaleimide (NEM) (Wako Pure Chemical Industries, Ltd.) was added to stabilize the thiol form (i.e., Compound II) by, it is believed, blocking the free sulfhydryl group by the derivatization to an NEM-adduct. The sample then was analyzed using High Performance Liquid Chromatography (HPLC). Finally, the results of the HPLC analysis of the plasma sample were compared to a known standard to determine the plasma concentration of the active form of Compound I. The standard of known concentration was prepared essentially as described above, with the exception that human plasma was isolated from humans who were not treated with Compound I. These "blank plasma" samples were combined with a known amount of Compound I.

[0088] The mean test results for plasma pharmacokinetic parameters, AUC _0-∞ (µg·h/mL), AUC _0-tz (µg·h/mL), C_max (µg/mL), t_1/2 (h), and t_max (h), of the active form of Compound I are summarized in Table 2.

[0089] As demonstrated by the data in Table 2, a pharmaceutical composition comprising a CETP inhibitor can achieve a maximum observed plasma concentration (C_max) of the CETP inhibitor, or active form thereof, in the bloodstream of a mammal of at least about 0.1 µg/mL at a dose of 300 mg when administered with food. For example, at a dose of 300 mg of Compound I, the C_max was about 0.16 µg/mL.

[0090] The data in Table 2 also demonstrates that a pharmaceutical composition comprising a CETP inhibitor can achieve a maximum observed plasma concentration (C_max) of the CETP inhibitor, or active form thereof, in the bloodstream of a mammal of at least about 0.35 µg/mL and an area under the plasma concentration-time curve (AUC_0-∞) of at least about 3.5 µg·h/mL, at a dose of 600 mg when administered with food. For example, at a dose of 600 mg of Compound I, the C_max was about 0.5 µg/mL, and the AUC_0-∞ was about 5 µg·h/mL.

[0091] Additionally, the data indicates that a pharmaceutical composition comprising a CETP inhibitor can achieve a maximum observed plasma concentration (C_max) of at least about 0.8 µg/mL and an area under the plasma concentration-time curve (AUC_0-∞) of at least about 7.5 µg·h/mL, at a dose of 900 mg when administered with food. For example, at a dose of 900 mg of Compound I, the C_max was about 0.9 µg/mL, and the AUC_0-∞ was about 9 µg·h/mL.

EXAMPLE 2

[0092] The effect of food on the absorption of a CETP inhibitor in patients was identified in a study designed to compare the bioavailability of 900 mg of Compound I orally administered to Caucasian male volunteers with and without food.

[0093] For this study each of six subjects received Compound I at a dose level of 900 mg in each of two treatment periods, once with food (after a standard breakfast) and once in the fasted state. There was a minimum of 7 days between each treatment period. This interval of 7 days between treatments was considered appropriate for eliminating any within-subject carryover effects.

[0094] The subjects received 900 mg of Compound I by administration of 3 tablets of 300 mg each. Tablet preparation and administration procedures were as described as in Example 1, with the following exceptions.

[0095] Doses were administered at similar times for each subject in each treatment period. Dosing commenced at approximately 08:30 hours. All subjects fasted from food and fluids (with the exception of water) from 22:00 hours on the day prior to dosing (Day 1) until breakfast on Day 1 (for subjects receiving Compound I in the fed state (i.e., with food)) or lunch-time on Day 1 (for subjects receiving Compound I in the fasted state), and during the evening prior to the post-study visit until laboratory safety evaluations had been performed on the following day. Water could be consumed at any time during the study, with the exception of the period up to 2 hours post-dose, when no fluids were permitted.

[0096] When subjects were administered Compound I in the fed state, they received a standard breakfast about 45 minutes prior to dosing as described in Example 1.

[0097] The mean test results for plasma pharmacokinetic parameters, AUC_0-∞ (µg·h/mL), AUC _0-tz (µg·h/mL), C_max (µg/mL), t_1/2(h), and t_max (h), of the active form of Compound I are summarized in Table 3.

[0098] The absorption of the active form of Compound I was relatively slow, with the time of maximum observed plasma concentration occurring at between 4 and 5 hours after administration of Compound I. As is apparent from Table 3, the time of maximum observed plasma concentration was similar after administration of Compound I with and without food. Additionally, the half life of the active form of Compound I was determined to be similar after administration of the drug with and without food.

[0099] Several of the pharmacokinetic parameters, however, were affected by the administration of Compound I with food. These include AUC_0-tz, AUC _0-∞, and C_max, which were 65%, 57%, and 126% higher, respectively, when Compound I was administered with food as compared with the administration of Compound I in the fasted state. These increases are noticeably apparent when the geometric mean plasma concentrations of the active form of Compound I were plotted in linear form in Figure 1 and plotted in semi-logarithmic form in Figure 2.

[0100] The observed increases in pharmacokinetic parameters when Compound I is administered with food indicate an increase in the bioavailability of the active form of the drug when compared to administration of the drug under fasted conditions.

[0101] Therefore, this example demonstrates that an increase in bioavailability of a CETP inhibitor results when the CETP inhibitor is administered with food relative to administration without food.

EXAMPLE 3

[0102] This example further illustrates the absorption of a CETP inhibitor (e.g., Compound I) when administered in a pharmaceutical composition according to the invention.

[0103] Japanese male human subjects were administered 100 mg, 300 mg, 600 mg, 900 mg, 1200 mg, 1500 mg, or 1800 mg of Compound I, or placebo, following a standard breakfast. Administration, dosing, and sampling schedules were commensurate with those described in Example 1. The tablets were prepared as described in Example 1.

[0104] The mean test results for plasma pharmacokinetics parameters of the active form of Compound I, AUC _0-∞ (µg·h/mL), C_max (µg/mL), and t_max (h), as well as t_1/2 α (h) and t_1/2 β, are summarized in Table 4. t_1/2 α signifies the half-life in the α-phase of plasma concentration of the active form of Compound I, and t_1/2 β signifies the half-life in the β-phase of plasma concentration of the active form of Compound I.

[0105] As demonstrated by the data in Table 4, a pharmaceutical composition comprising a CETP inhibitor can achieve a maximum observed plasma concentration (C_max) of the CETP inhibitor, or active form thereof, in the bloodstream of a mammal of at least about 0.1 µg/mL and an area under the plasma concentration-time curve (AUC_0-∞) of at least about 0.5 µg·h/mL, at a dose of 300 mg when administered with food. For example, at a dose of 300 mg of Compound I, the C_max was about 0.2 µg/mL, and the AUC_0-∞ was about 2 µg·h/mL.

[0106] The data in Table 4 also demonstrates that a pharmaceutical composition comprising a CETP inhibitor can achieve a maximum observed plasma concentration (C_max) of at least about 0.35 µg/mL and an area under the plasma concentration-time curve (AUC_0-∞) of the CETP inhibitor, or active form thereof, in the bloodstream of a mammal of at least about 3.5 µg·h/mL, at a dose of 600 mg when administered with food. For example, at a dose of 600 mg of Compound I, the C_max was about 1 µg/mL, and the AUC_0-∞ was about 10 µg·h/mL.

[0107] Additionally, the data indicates that a pharmaceutical composition comprising a CETP inhibitor can achieve a maximum observed plasma concentration (C_max) of at least about 0.8 µg/mL and an area under the plasma concentration-time curve (AUC_0-∞) of at least about 7.5 µg·h/mL, at a dose of 900 mg when administered with food. For example, at a dose of 900 mg of Compound I, the C_max was about 1.7 µg/mL, and the AUC_0-∞ was about 15 µg·h/mL.

EXAMPLE 4

[0108] In a similar study to that described in Example 2, the effect of food on the absorption of the active form of Compound I in patients was identified in a study designed to compare the bioavailability of 600 mg of Compound I orally administered to Japanese male volunteers with and without food.

[0109] Administration, dosing, and sampling schedules were commensurate with those described in Example 2. However, patients were administered 600 mg (rather than 900 mg) of Compound I with and without food. Patients were administered two tablets of 300 mg each. The tablets were prepared as described in Example 1.

[0110] The mean test results for plasma pharmacokinetics parameters of the active form of Compound I, AUC _0-∞ (µg·h/mL), C_max (µg/mL), and t_max (h), as well as t_1/2 α (h) and t_1/2 β, are summarized in Table 5.

t1/2α (h)	5.5 ± 1.4	2.7 ± 0.6
t1/2β (h)	20.6 ± 3.0	15.1 ± 2.1

[0111] Pharmacokinetics parameters, such as maximum observed plasma concentration (C_max) and area under the plasma concentration-time curve from time zero to infinity (AUC_0-∞), were affected by administration of Compound I with food. The C_max value after administration of 600 mg of Compound I was 1.029 µg/mL when administered with food and only 0.316 µg/mL when administered without food. The AUC_0-∞ value after administration of 600 mg of Compound I was 10.458 µg h/mL when administered with food and only 5.395 µg h/mL when administered without food. Thus, the C_max and AUC_0-∞ were about 3 and 2 times higher, respectively, when the patients were administered the CETP inhibitor with food as compared to without food.

[0112] The observed increases in the pharmacokinetic parameters when Compound I is administered with food indicate that the active form of the drug is more readily absorbed when administered with food, such as after a meal. Thus, the administration of a CETP inhibitor (e.g., Compound I) with food results in an increase in the bioavailability of the active form of the drug relative to the administration of the CETP inhibitor under fasted conditions.

EXAMPLE 5

[0113] This example illustrates the effect of the administration of a CETP inhibitor (e.g., Compound I) on CETP activity when administered in a pharmaceutical composition according to the invention.

[0114] Caucasian male human patients were orally administered 100 mg, 200 mg, 600 mg, 900 mg, 1200 mg, 1500 mg, 1800 mg of Compound I, or placebo, following breakfast. Administration, dosing, and sampling schedules were substantially similar to those described in Example 1. The tablets were prepared as described in Example 1.

[0115] The procedure for determining CETP activity was substantially similar to the procedures described in Tollefson et al., Methods Enzymol., 129, 797-816 (1986), and Kato et al., J. Biol. Chem., 264, 4082-4087 (1989).

[0116] CETP activity and changes from baseline (pre-dose) were measured, and the resulting data is summarized in Table 6 as percentage change from baseline.

[0117] As demonstrated by the data in Table 6, a pharmaceutical composition comprising a CETP inhibitor can achieve a decrease in CETP activity of at least about 10% relative to pre-dose levels at a dose of 300 mg. For example, 6 hours after the administration of 300 mg of Compound I, CETP activity had decreased by 13%.

[0118] The data in Table 6 also demonstrates that a pharmaceutical composition comprising a CETP inhibitor can achieve a decrease in CETP activity of at least about 25% relative to pre-dose levels at a dose of 600 mg. For example, 6 hours after the administration of 600 mg of Compound I, CETP activity had decreased by 36%.

[0119] Additionally, the data indicates that a pharmaceutical composition comprising a CETP inhibitor can achieve a decrease in CETP activity of at least about 35% relative to placebo at a dose of 900 mg. For example, 6 hours after the administration of 900 mg of Compound I, CETP activity had decreased by 55%.

EXAMPLE 6

[0120] The effect of food on the absorption of the active form of Compound I in Caucasian male patients was identified in a study designed to compare the CETP activity following the oral administration of 900 mg of Compound I with and without food.

[0121] Administration, dosing, and sampling schedules were substantially similar to those described in Example 1.

[0122] The procedure for determining CETP activity is described in Example 5.

[0123] CETP activity and changes from baseline (pre-dose) over time were measured, and the resulting data is summarized in Table 7. The mean changes from baseline (pre-dose) in CETP activity over time are set out in the plot of Figure 3.

Table 7 - Mean (S.D.) Changes from Baseline (Pre-dose) in CETP Activity

Treatment Protocol	Pre-dose	Percent Changes from Pre-dose (standard deviation)

	(16.0)	(2.2)	(2.4)	(2.2)	(3.1)	(4.7)	(3.8)

[0124] A clear difference in CETP activity was observed when Compound I was administered with and without food. Inhibition of CETP activity was much more marked in the fed treatment protocol as compared with the fasted treatment protocol. For example, between 4 and 24 hours post-dose, there was a significant decrease in CETP activity in the fed versus the fasted state. Such a decrease in CETP activity indicates increased bioavailability of the active form of the drug when administered with food as compared to administration of the drug without food.

[0125] The relationships between plasma concentrations of the active form of Compound I and inhibition of CETP activity for the fed and fasted states are illustrated by the plots of Figures 4 and 5, respectively. As plasma concentrations of the active form of Compound I increased, the inhibitory effect on CETP increased (i.e., CETP activity decreased).

EXAMPLE 7

[0126] This example further illustrates the effect of the administration of a CETP inhibitor (e.g., Compound I) on the CETP activity when administered in a pharmaceutical composition according to the invention.

[0127] Japanese male human patients were orally administered 100 mg, 300 mg, 600 mg, 900 mg, 1200 mg, 1500 mg, or 1800 mg of Compound I, or placebo, following breakfast.

[0128] Administration, dosing, and sampling schedules were commensurate with those described in Example 1. The tablets were prepared as described in Example 1.

[0129] Relative CETP activities (calculated as a percentage of baseline CETP activity) and standard deviations (SD) were measured, and the resulting data is summarized in Table 8.

[0130] As demonstrated by the data in Table 8, a pharmaceutical composition comprising a CETP inhibitor can achieve a decrease in CETP activity of at least about 10% relative to pre-dose levels at a dose of 300 mg. For example, 6 hours after the administration of 300 mg of Compound I, CETP activity is about 80.5% of the pre-dose value. Therefore, CETP activity has decreased by about 19.5% following the administration of Compound I.

[0131] The data in Table 8 also demonstrates that a pharmaceutical composition comprising a CETP inhibitor can achieve a decrease in CETP activity of at least about 25% relative to pre-dose levels at a dose of 600 mg. For example, 6 hours after the administration of 600 mg of Compound I, CETP activity is only about 38% of the pre-dose value. Therefore, CETP activity has decreased by about 62% following the administration of Compound I.

[0132] Additionally, the data indicates that a pharmaceutical composition comprising a CETP inhibitor can achieve a decrease in CETP activity of at least about 35% relative to pre-dose CETP activity at a dose of 900 mg. For example, 4 hours after the administration of 900 mg of Compound I, CETP activity is only about 24% of the pre-dose value. Thus, CETP activity has decreased by about 76%.

EXAMPLE 8

[0133] In a similar study to that described in Example 6, the effect of food on the absorption of the active form of Compound I in Japanese male patients was identified in a study designed to compare the relative CETP activity following the oral administration of 600 mg of Compound I with and without food.

[0134] Administration, dosing, and sampling schedules were commensurate with those described in Examples 1 and 6. However, patients were administered 600 mg (rather than 900 mg as in Example 6) of Compound I with and without food. Patients were administered two tablets of 300 mg each. The tablets were prepared as described in Example 1.

[0135] Relative CETP activities (calculated as a percentage of baseline CETP activity) and standard deviations (SD) were measured, and the resulting data is summarized in Table 9.

Table 9 - Relative CETP Activity

Treatment Protocol	Pre-dose	CETP Activity Relative to Pre-dose (standard deviation)
		1 h	2h	4h	6h	8 h	24 h	Post-study
Fed	100	100.4	87.8	52.6	37.6	39.1	65.5	102.9
	(0.0)	(1.9)	(9.2)	(13.4)	(6.6)	(8.3)	(5.7)	(7.3)
Fasted	100	102.1	99.6	96.5	89.5	87.8	92.6	100.4
	(0.0)	(3.6)	(2.1)	(3.1)	(2.0)	(4.6)	(3.0)	(2.8)

[0136] A clear difference in CETP relative activity was observed when Compound I was administered with and without food, consistent with the results discussed in Example 2. Inhibition of CETP activity was much more marked in the fed treatment protocol as compared with the fasted treatment protocol. For example, between 4 and 24 hours post-dose, there was a significant decrease in CETP activity in the fed versus the fasted state. Specifically, the inhibition of CETP activity following the administration of Compound I with food reached its peak at 6 hours post-administration with 37.6% CETP activity relative to baseline. In contrast, the inhibition of CETP activity following the administration of Compound I without food reached its peak at 8 hours post-administration with 87.8% CETP activity relative to baseline. Such a decrease in the relative CETP activity following the administration of Compound I with food indicates increased bioavailability of the active form of the drug when administered with food as compared to the administration of the drug without food.

EXAMPLE 9

[0137] This example illustrates the effect of the administration of Compound I on CETP activity and lipid levels in healthy individuals.

[0138] About 200 volunteers (men and women) were randomized to receive placebo or to receive 300 mg (low dose), 600 mg (medium dose) or 900 mg (high dose) of Compound I per day for 4 weeks. Each patient took three tablets after breakfast each day for 4 weeks. Patients either took three placebo tablets (placebo); one 300 mg tablet and two placebo tablets (low dose); two 300 mg tablets and one placebo tablet (medium dose); or three 300 mg tablets (high dose). Tablet preparation was as described as in Example 1.

[0139] The testing period consisted of (a) a run-in period of 4 weeks, followed by (b) 4 weeks of treatment, and (c) 4 weeks of monitoring. Blood samples were drawn after an overnight fast. For CETP activity assays, blood was drawn before Compound I intake and during and after treatment. HDL-C was determined with a heparin MnCl₂ precipitation reagent and LDL-C was calculated by the Friedewald formula (see, de Grooth et al., supra). CETP activity was measured as described in Example 5.

[0140] Table 10 describes the values of the assayed properties ((mean) ± standard deviation) at baseline (i.e., before administration of Compound I). Table 11 describes the absolute changes in the assayed properties after 4 weeks of treatment The data points for absolute changes from baseline (i.e., before administration of Compound I) in CETP activity, total cholesterol (TC), HDL-C, LDL-C, and total cholesterol/HDL-C (TC/HDL-C) ratio are provided below. Analysis was done by fitting an ANOVA model with separate treatment effects for the four groups (i.e., placebo, 300 mg, 600 mg, or 900 mg of Compound I).

* P≤0.01; † P≤0.001; ‡ P≤0.0001 (each group versus placebo)

[0141] As demonstrated by the data in Tables 10 and 11, a pharmaceutical composition comprising a CETP inhibitor can achieve an increase in HDL-C levels of about 10%, about 15%, and about 20% at dose levels of 300 mg, 600 mg, and 900 mg of Compound I, respectively, following daily treatment for 4 weeks. For example, HDL-C levels were increased by about 15%, about 26%, and about 34% relative to baseline levels of the 300 mg, 600 mg, and 900 mg treatment groups, respectively.

[0142] Tables 10 and 11 also illustrate that the TC/HDL-C ratio can be decreased by about 5%, about 10%, and about 15% at dose levels of 300 mg, 600 mg, and 900 mg of Compound I, respectively, following daily treatment for 4 weeks. For example, the TC/HDL-C ratios were decreased by about 13%, about 18%, and about 23% relative to baseline levels of the 300 mg, 600 mg, and 900 mg treatment groups, respectively.

[0143] The data in Tables 10 and 11 also demonstrate that a pharmaceutical composition comprising a CETP inhibitor can achieve a decrease in CETP activity of at least about 10%, about 25%, and about 35% relative to pre-dose levels at a dose levels of 300 mg, 600 mg, or 900 mg of the CETP inhibitor (e.g., Compound I), respectively, following daily administration of the CETP inhibitor with food for 4 weeks. For example, CETP activity decreased by about 17%, about 33%, and about 39% relative to baseline levels of the 300 mg, 600 mg, and 900 mg treatment groups, respectively.

EXAMPLE 10

[0144] The following example illustrates the method of manufacturing the formulation comprising 300 mg of Compound I described in Example 1.

[0145] In Step 1, Compound I was pulverized by jet mill. A particle size distribution of less than about 10 µm (e.g., about 5 µm) of pulverized Compound I was tested by the use of an in-process control.

[0146] In Step 2, the pulverized Compound I was mixed with crospovidone by drum mixer, resulting in a mixed powder.

[0147] In Step 3, the mixed powder of Step 2 was passed through a screen #12 approximately three times.

[0148] In Step 4, the screened, mixed powder of Step 3 was pre-mixed by wet granulator.

[0149] In Step 5, hydroxypropylmethylcellulose 2910 was dissolved in purified water using a propeller mixer.

[0150] In Step 6, the mixed powder of Step 4 was granulated using the solution of Step 5 as a binder in the wet granulator. This step yielded four batches of granulated material.

[0151] In Step 7, two of the four batches of granulated material of Step 6 were transferred to a fluidized bed dryer and dried. The process was repeated for the remaining two batches.

[0152] In Step 8, the granulated material of Step 7 was passed through a screen #22. Moisture content and particle size distribution were tested by an in-process control.

[0153] In Step 9, all of the dried granulated material of Step 8 was mixed by drum mixer.

[0154] In Step 10, the granulated material of Step 9 was mixed with low substituted hydroxypropyl cellulose by drum mixer to yield mixed granulated material.

[0155] In Step 11, the mixed granulated material of Step 10 was mixed with talc and magnesium stearate by drum mixer. Content uniformity, specific volume, and angle of repose were tested by an-process control.

[0156] In Step 12, the mixed granulated material was compressed by a tableting machine. Content uniformity, tablet hardness, thickness, and friability were assayed. Additionally, dissolution and weight variation tests were performed.

[0157] This example demonstrates that a formulation comprising 300 mg Compound I, hydroxypropylmethyl cellulose 2910, talc, magnesium stearate, crospovidone, and low substituted hydroxypropyl cellulose (as described in Example 1) can be formed into an oral dosage form.
