Cardiovascular disease (CVD) is the leading cause of mortality and morbidity globally (The Global Burden of Disease: 2004 Update. In: World Health Organization; 2004). Despite improvements resulting from treatment of risk factors (Circulation. 2017; 135(10):e146.) by 2030 nearly half of the US population will suffer from CVD.
Cardiac damage, valvular heart disease such as aortic stenosis, vascular hypertension, and aging are the major factors leading to pressure overload of the pump function of the heart. Hypertrophy of the left ventricle of the heart is a normal response of the heart to such pressure overload. Hypertrophy enables cardiomyocytes to generate the additional force required to compensate for the increased pressure load and maintain necessary pump function. At least 10% of the population in industrialized societies have severe hypertension, which leads not only to left ventricular hypertrophy and secondary heart failure, but also myocardial infarctions and lethal arrhythmias (1). Aging is another common cause of pressure overload of the pump, leading to diastolic dysfunction and concentric remodeling in the left ventricle, though in many cases systolic function is unaffected until late-life senescence (2). The initially appropriate and compensatory left ventricular remodeling may progress to the point of pathophysiology, however, as ischemic and otherwise damaged cardiomyocytes degenerate, fibrosis begins and progresses, and chambers dilate, causing a progressive decline in cardiac pump function (3-9).
The maladaptive remodeling process leading to heart failure can be conceptually divided into hypertrophic changes of cardiomyocytes, and alterations to the normal patterning of the extracellular matrix (ECM) network. Changes in both systolic and diastolic function can be attributed back these two categories (10). The cardiac ECM provides structural support for the myocardium, and generates cytokines, growth factors, and modulatory proteins that modify myocardial function (11). The appearance of adverse ECM remodeling represents a significant etiologic milestone in the progression to frank heart failure. Normal basement membrane fibronectin, laminin, and collagens bind cardiomyocytes to the interstitial ECM and promote transmembrane signaling through integrin receptors (12), with collagen fibers architecturally organizing myocytes and muscle fibers to permit optimal force generation and transmission. However, when collagen fibrils and struts are lost, cardiomyocyte contraction slippage, chamber dilation, and worsening contractile dysfunction may occur (13). As well, with increasing disease promotion through worsening of the factors described above, fibrillar collagens accumulate in the left ventricular myocardium, causing increased myocardial stiffness (2, 14, 15).
The extracellular matrix of the heart, like skeletal bone and other structural components of the body, undergoes a continuous process of synthesis, degradation, and resynthesis to maintain appropriate structure and strength. Though this healthy remodeling of the cardiac ECM requires healthy proteolysis, proteolysis also is involved in adverse remodeling as part of disease processed including progressive heart failure. Of note, increased activation and expression of matrix metalloproteinases (MMPs), Zn-dependent proteases, are associated with heart failure and thus implicated in the remodeling process of progressive pump failure (16-18). There are 25 members of the mammalian MMP superfamily, including stromelysins, gelatinases, collagenases, matrilysins, membrane-type MMPs, and other MMPs (19). Their various actions are endogenously regulated by tissue inhibitors of metalloproteinases (TIMPs: TIMP1-4), which noncovalently bind with generally low selectivity to form 1:1 complexes with both active and pro-form MMPs. Each myocardial ECM protein serves as a substrate for at least one cardiac MMP (20), which also inactivate and activate ECM-derived cytokines and growth factors (21, 22).
Involvement of MMPs with pathological remodeling of myocardium leading to and worsening heart failure has been characterized in both plasma and left ventricle of animal disease models and humans (8, 16-18, 23-46). While the majority of substrates of MMPs are accessible from extracellular space, more recently an intracellular role in regulation of calcium handling important for excitation-contraction coupling and direct effects on sarcomeric function have been reported for MMPs (47-53). In humans, elevated MMP2 and MMP9 are strongly associated with diastolic dysfunction or heart failure in a number of studies (54-61).
Evidence that MMPs are not simply associated, but cause, pathological left ventricular and overall cardiac remodeling leading to reduced pump function and disease have been generated through both genetic and pharmacological interventions. Nonselective pharmacologic inhibition of MMPs has been demonstrated to significantly reduce pathological remodeling associated with various disease triggers in animal models (28, 40, 62-69). Data showing that selective MMP inhibition, in particular sparing MMP1 action, provides benefit for cardiac remodeling has been generated for MMP-1, MMP-2, MMP-9, TIMP 1, and TIMP-3 (70-74). The strongest bodies of evidence generate the therapeutic hypothesis that selective inhibition of at least MMP-2 and MMP-9 promotes less adverse cardiac function after a variety of interventions that cause cardiac pump failure (59, 75, 76).
MMP9 mice are protected from diastolic dysfunction and fibrosis accumulation (77), as well as remodeling after infarction (59)(75). MMP2 expression, as well as MMP9 expression, has been demonstrated to be elevated in pressure overload hypertrophy in both spontaneously hypertensive (66) and in Dahl salt-sensitive hypertensive rats (43). Most convincingly, both transgenically overexpressing MMP2 and transgenically overexpressing MMP9 mice develop pathologically fibrotic myocardium (78, 79), while MMP2 and MMP9 genetically deleted mice are protected structurally and functionally in disease models of heart failure, results that are nicely recapitulated with prototype pharmacological inhibitors blocking MMP2 and/or MMP9 action (80, 81).
TACE/ADAM17 (Tumor necrosis factor-α-converting enzyme; A Disintegrin And Metalloproteinase 17) is a soluble or membrane-bound metalloproteinase primarily responsible for activation of proTNF-α, while also targeting proteins such as fractalkine, amyloid precursor proteins, and CD40. ADAM17/TACE is involved in cancer, vascular disorders, and inflammatory diseases such as rheumatoid arthritis and focal ischemic injury. The catalytic domain of ADAM17/TACE is able to cleave proTNF-α and is used in inhibitor screening.
There is a strong need to develop therapeutic treatment options directed specifically at reversing the underlying cause of heart failure (HF), which is an impaired pumping function of the heart. However, current standard of care for HF and other CVD does not correct the underlying defect causing loss of pump function, which is loss of functioning heart muscle cells, or cardiomyocytes. Instead, existing pharmacotherapies target non-cardiac, peripheral characteristics of the cardiovascular system, including reducing pre-load and after-load by targeting blood pressure, reducing blood volume (aldosterone antagonists, diuretics), or lowering lipids contributing to vascular disease.

Furthermore, in some embodiments, the compounds described herein exist as geometric isomers. In some embodiments, the compounds described herein possess one or more double bonds. The compounds presented herein include all cis, trans, syn, anti, entgegen (E), and zusammen (Z) isomers as well as the corresponding mixtures thereof. In some situations, compounds exist as tautomers. The compounds described herein include all possible tautomers within the formulas described herein. In some situations, the compounds described herein possess one or more chiral centers and each center exists in the R configuration, or S configuration. The compounds described herein include all diastereomeric, enantiomeric, and epimeric forms as well as the corresponding mixtures thereof. In additional embodiments of the compounds and methods provided herein, mixtures of enantiomers and/or diastereoisomers, resulting from a single preparative step, combination, or interconversion are useful for the applications described herein.
In some embodiments, the compounds described herein are prepared as their individual stereoisomers by reacting a racemic mixture of the compound with an optically active resolving agent to form a pair of diastereoisomeric compounds, separating the diastereomers and recovering the optically pure enantiomers. In some embodiments, dissociable complexes are preferred (e.g., crystalline diastereomeric salts). In some embodiments, the diastereomers have distinct physical properties (e.g., melting points, boiling points, solubilities, reactivity, etc.) and are separated by taking advantage of these dissimilarities. In some embodiments, the diastereomers are separated by chiral chromatography, or preferably, by separation/resolution techniques based upon differences in solubility. In some embodiments, the optically pure enantiomer is then recovered, along with the resolving agent, by any practical means that would not result in racemization.
In some embodiments, the compounds described herein exist in their isotopically-labeled forms. In some embodiments, the methods disclosed herein include methods of treating diseases by administering such isotopically-labeled compounds. In some embodiments, the methods disclosed herein include methods of treating diseases by administering such isotopically-labeled compounds as pharmaceutical compositions. Thus, in some embodiments, the compounds disclosed herein include isotopically-labeled compounds, which are identical to those recited herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that are incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, sulfur, fluorine and chloride, such as 2H, 3H, 13C, 14C, 15N, 16O, 17O, 31P, 32P, 35S, 18F, and 36Cl, respectively. Compounds described herein, and the pharmaceutically acceptable salts, esters, solvate, hydrates or derivatives thereof which contain the aforementioned isotopes and/or other isotopes of other atoms are within the scope of this invention. Certain isotopically-labeled compounds, for example those into which radioactive isotopes such as 3H and 14C are incorporated, are useful in drug and/or substrate tissue distribution assays. Tritiated, i. e., 3H and carbon-14, i. e., 14C, isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with heavy isotopes such as deuterium, i.e., 2H, produces certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements. In some embodiments, the isotopically labeled compounds, pharmaceutically acceptable salt, ester, solvate, hydrate or derivative thereof is prepared by any suitable method.
In some embodiments, the compounds described herein are labeled by other means, including, but not limited to, the use of chromophores or fluorescent moieties, bioluminescent labels, or chemiluminescent labels.
In some embodiments, the compounds described herein exist as their pharmaceutically acceptable salts. In some embodiments, the methods disclosed herein include methods of treating diseases by administering such pharmaceutically acceptable salts. In some embodiments, the methods disclosed herein include methods of treating diseases by administering such pharmaceutically acceptable salts as pharmaceutical compositions.
In some embodiments, the compounds described herein possess acidic or basic groups and therefore react with any of a number of inorganic or organic bases, and inorganic and organic acids, to form a pharmaceutically acceptable salt. In some embodiments, these salts are prepared in situ during the final isolation and purification of the compounds of the invention, or by separately reacting a purified compound in its free form with a suitable acid or base, and isolating the salt thus formed.
In some embodiments, the compounds described herein are formulated as agents which are converted in vivo to active forms in order to alter the biodistribution or the pharmacokinetics for a particular agent. For example, a carboxylic acid group can be esterified, e.g., with a methyl group or an ethyl group to yield an ester. When the ester is administered to a subject, the ester is cleaved, enzymatically or non enzymatically, reductively, oxidatively, or hydrolytically, to reveal the anionic group. An anionic group can be esterified with moieties (e.g., acyloxymethyl esters) which are cleaved to reveal an intermediate agent which subsequently decomposes to yield the active agent. The prodrug moieties may be metabolized in vivo by esterases or by other mechanisms to carboxylic acids. Alternatively, other functional groups may be modified into a prodrug form. For instance, an amine group may be converted into a carbamate or amide which would be cleavable in vivo.
In some embodiments, the compounds described herein exist as solvates. The invention provides for methods of treating diseases by administering such solvates. The invention further provides for methods of treating diseases by administering such solvates as pharmaceutical compositions.
Solvates contain either stoichiometric or non-stoichiometric amounts of a solvent, and, in some embodiments, are formed during the process of crystallization with pharmaceutically acceptable solvents such as water, ethanol, and the like. Hydrates are formed when the solvent is water, or alcoholates are formed when the solvent is alcohol. Solvates of the compounds described herein are conveniently prepared or formed during the processes described herein. By way of example only, hydrates of the compounds described herein are conveniently prepared by recrystallization from an aqueous/organic solvent mixture, using organic solvents including, but not limited to, dioxane, tetrahydrofuran or methanol. In addition, the compounds provided herein exist in unsolvated as well as solvated forms. In general, the solvated forms are considered equivalent to the unsolvated forms for the purposes of the compounds and methods provided herein.
In certain embodiments, the compounds described herein are administered as a pure chemical. In other embodiments, the compounds described herein are combined with a pharmaceutically suitable or acceptable carrier (also referred to herein as a pharmaceutically suitable (or acceptable) excipient, physiologically suitable (or acceptable) excipient, or physiologically suitable (or acceptable) carrier) selected on the basis of a chosen route of administration and standard pharmaceutical practice as described, for example, in Remington: The Science and Practice of Pharmacy (Gennaro, 21st Ed. Mack Pub. Co., Easton, PA (2005)).
Accordingly, provided herein is a pharmaceutical composition comprising at least one compound described herein, or a pharmaceutically acceptable salt, together with one or more pharmaceutically acceptable carriers. The carrier(s) (or excipient(s)) is acceptable or suitable if the carrier is compatible with the other ingredients of the composition and not deleterious to the recipient (i.e., the subject) of the composition.
One embodiment provides a pharmaceutical composition comprising a pharmaceutically acceptable carrier and a compound of Formula (I) or (Ia) or (Ib) or (Ic) or (II) or (III), or a pharmaceutically acceptable salt thereof.
Another embodiment provides a pharmaceutical composition consisting essentially of a pharmaceutically acceptable carrier and a compound of Formula (I) or (Ia) or (Ib) or (Ic) or (II) or (III), or a pharmaceutically acceptable salt thereof.
In certain embodiments, the compound as described herein is substantially pure, in that it contains less than about 5%, or less than about 1%, or less than about 0.1%, of other organic small molecules, such as contaminating intermediates or by-products that are created, for example, in one or more of the steps of a synthesis method.
These formulations include those suitable for oral, topical, buccal, parenteral (e.g., subcutaneous, intramuscular, intradermal, or intravenous), or aerosol administration.
Exemplary pharmaceutical compositions are used in the form of a pharmaceutical preparation, for example, in solid, semisolid or liquid form, which includes one or more of a disclosed compound, as an active ingredient, in a mixture with an organic or inorganic carrier or excipient suitable for external, enteral or parenteral applications. In some embodiments, the active ingredient is compounded, for example, with the usual non-toxic, pharmaceutically acceptable carriers for tablets, pellets, capsules, suppositories, solutions, emulsions, suspensions, and any other form suitable for use. The active object compound is included in the pharmaceutical composition in an amount sufficient to produce the desired effect upon the process or condition of the disease.
In some embodiments, a compound of Formula (I) or (Ia) or (Tb) or (Ic) or (II) or (III), described herein are administered to subjects in a biologically compatible form suitable for topical administration to treat or prevent dermal diseases, disorders or conditions. By “biologically compatible form suitable for topical administration” is meant a form of the compound of Formula (I) or (Ia) or (Ib) or (Ic) or (II) or (III), to be administered in which any toxic effects are outweighed by the therapeutic effects of the inhibitor. Administration of a compound of Formula (I) or (Ia) or (Ib) or (Ic) or (II) or (III), as described herein can be in any pharmacological form including a therapeutically effective amount of a compound of Formula (I) or (Ia) or (Tb) or (Ic) or (II) or (III), alone or in combination with a pharmaceutically acceptable carrier.
Topical administration of a compound of Formula (I) or (Ia) or (Ib) or (Ic) or (II) or (III), may be presented in the form of an aerosol, a semi-solid pharmaceutical composition, a powder, or a solution. By the term “a semi-solid composition” is meant an ointment, cream, salve, jelly, or other pharmaceutical composition of substantially similar consistency suitable for application to the skin. Examples of semi-solid compositions are given in Chapter 17 of The Theory and Practice of Industrial Pharmacy, Lachman, Lieberman and Kanig, published by Lea and Febiger (1970) and in Chapter 67 of Remington's Pharmaceutical Sciences, 15th Edition (1975) published by Mack Publishing Company.
Dermal or skin patches are another method for transdermal delivery of the therapeutic or pharmaceutical compositions described herein. Patches can provide an absorption enhancer such as DMSO to increase the absorption of the compounds. Patches can include those that control the rate of drug delivery to the skin. Patches may provide a variety of dosing systems including a reservoir system or a monolithic system, respectively. The reservoir design may, for example, have four layers: the adhesive layer that directly contacts the skin, the control membrane, which controls the diffusion of drug molecules, the reservoir of drug molecules, and a water-resistant backing. Such a design delivers uniform amounts of the drug over a specified time period, the rate of delivery has to be less than the saturation limit of different types of skin. The monolithic design, for example, typically has only three layers: the adhesive layer, a polymer matrix containing the compound, and a water-proof backing. This design brings a saturating amount of drug to the skin. Thereby, delivery is controlled by the skin. As the drug amount decreases in the patch to below the saturating level, the delivery rate falls.
In one embodiment, the topical composition may, for example, take the form of hydrogel based on polyacrylic acid or polyacrylamide; as an ointment, for example with polyethylene glycol (PEG) as the carrier, like the standard ointment DAB 8 (50% PEG 300, 50% PEG 1500); or as an emulsion, especially a microemulsion based on water-in-oil or oil-in-water, optionally with added liposomes. Suitable permeation accelerators (entraining agents) include sulfoxide derivatives such as dimethylsulfoxide (DMSO) or decylmethylsulfoxide (decyl-MSO) and transcutol (diethyleneglycolmonoethylether) or cyclodextrin; as well as pyrrolidones, for example 2-pyrrolidone, N-methyl-2-pyrrolidone, 2-pyrrolidone-5-carboxylic acid, or the biodegradable N-(2-hydroxyethyl)-2-pyrrolidone and the fatty acid esters thereof; urea derivatives such as dodecylurea, 1,3-didodecylurea, and 1,3-diphenylurea; terpenes, for example D-limonene, menthone, α-terpineol, carvol, limonene oxide, or 1,8-cineol.
Ointments, pastes, creams and gels also can contain excipients, such as starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites, silicic acid, and talc, or mixtures thereof. Powders and sprays also can contain excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder, or mixtures of these substances. Solutions of nanocrystalline antimicrobial metals can be converted into aerosols or sprays by any of the known means routinely used for making aerosol pharmaceuticals. In general, such methods comprise pressurizing or providing a means for pressurizing a container of the solution, usually with an inert carrier gas, and passing the pressurized gas through a small orifice. Sprays can additionally contain customary propellants, such a chlorofluorohydrocarbons and volatile unsubstituted hydrocarbons, such as butane and propane.
In some embodiments for preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical carrier, e.g., conventional tableting ingredients such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate or gums, and other pharmaceutical diluents, e.g., water, to form a solid preformulation composition containing a homogeneous mixture of a disclosed compound or a non-toxic pharmaceutically acceptable salt thereof. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition is readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules.
In solid dosage forms for oral administration (capsules, tablets, pills, dragees, powders, granules and the like), the subject composition is mixed with one or more pharmaceutically acceptable carriers, such as sodium citrate or dicalcium phosphate, and/or any of the following: (1) fillers or extenders, such as starches, cellulose, microcrystalline cellulose, silicified microcrystalline cellulose, lactose, sucrose, glucose, mannitol, and/or silicic acid; (2) binders, such as, for example, carboxymethylcellulose, hypromellose, alginates, gelatin, polyvinyl pyrrolidone, sucrose and/or acacia; (3) humectants, such as glycerol; (4) disintegrating agents, such as crospovidone, croscarmellose sodium, sodium starch glycolate, agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; (5) solution retarding agents, such as paraffin; (6) absorption accelerators, such as quaternary ammonium compounds; (7) wetting agents, such as, for example, docusate sodium, cetyl alcohol and glycerol monostearate; (8) absorbents, such as kaolin and bentonite clay; (9) lubricants, such a talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof; and (10) coloring agents. In the case of capsules, tablets and pills, in some embodiments, the compositions comprise buffering agents. In some embodiments, solid compositions of a similar type are also employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugars, as well as high molecular weight polyethylene glycols and the like.
In some embodiments, a tablet is made by compression or molding, optionally with one or more accessory ingredients. In some embodiments, compressed tablets are prepared using binder (for example, gelatin or hydroxypropylmethyl cellulose), lubricant, inert diluent, preservative, disintegrant (for example, sodium starch glycolate or cross-linked sodium carboxymethyl cellulose), surface-active or dispersing agent. In some embodiments, molded tablets are made by molding in a suitable machine a mixture of the subject composition moistened with an inert liquid diluent. In some embodiments, tablets, and other solid dosage forms, such as dragées, capsules, pills and granules, are scored or prepared with coatings and shells, such as enteric coatings and other coatings.
Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the subject composition, in some embodiments, the liquid dosage forms contain inert diluents, such as, for example, water or other solvents, solubilizing agents and emulsifiers, such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor and sesame oils), glycerol, tetrahydrofuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, cyclodextrins and mixtures thereof.
In some embodiments, suspensions, in addition to the subject composition, contain suspending agents as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, and mixtures thereof.
In some embodiments, powders and sprays contain, in addition to a subject composition, excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder, or mixtures of these substances. In some embodiments, sprays additionally contain customary propellants, such as chlorofluorohydrocarbons and volatile unsubstituted hydrocarbons, such as butane and propane.
Compositions and compounds disclosed herein alternatively are administered by aerosol. This is accomplished by preparing an aqueous aerosol, liposomal preparation or solid particles containing the compound. In some embodiments, a non-aqueous (e.g., fluorocarbon propellant) suspension is used. In some embodiments, sonic nebulizers are used because they minimize exposing the agent to shear, which results in degradation of the compounds contained in the subject compositions. Ordinarily, an aqueous aerosol is made by formulating an aqueous solution or suspension of a subject composition together with conventional pharmaceutically acceptable carriers and stabilizers. The carriers and stabilizers vary with the requirements of the particular subject composition, but typically include non-ionic surfactants (Tweens, Pluronics, or polyethylene glycol), innocuous proteins like serum albumin, sorbitan esters, oleic acid, lecithin, amino acids such as glycine, buffers, salts, sugars or sugar alcohols. Aerosols generally are prepared from isotonic solutions.
Pharmaceutical compositions suitable for parenteral administration comprise a subject composition in combination with one or more pharmaceutically-acceptable sterile isotonic aqueous or non-aqueous solutions, dispersions, suspensions or emulsions, or sterile powders which are reconstituted into sterile injectable solutions or dispersions just prior to use, which, in some embodiments, contain antioxidants, buffers, bacteriostats, solutes which render the formulation isotonic with the blood of the intended recipient or suspending or thickening agents.
Examples of suitable aqueous and non-aqueous carriers which are employed in the pharmaceutical compositions include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the like), and suitable mixtures thereof, vegetable oils, such as olive oil, and injectable organic esters, such as ethyl oleate and cyclodextrins. Proper fluidity is maintained, for example, by the use of coating materials, such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants
The dose of the composition comprising at least one compound described herein differs, depending upon the patient's (e.g., human) condition, that is, stage of the disease, general health status, age, and other factors.
Pharmaceutical compositions are administered in a manner appropriate to the disease to be treated (or prevented). An appropriate dose and a suitable duration and frequency of administration will be determined by such factors as the condition of the patient, the type and severity of the patient's disease, the particular form of the active ingredient, and the method of administration. In general, an appropriate dose and treatment regimen provides the composition(s) in an amount sufficient to provide therapeutic and/or prophylactic benefit (e.g., an improved clinical outcome, such as more frequent complete or partial remissions, or longer disease-free and/or overall survival, or a lessening of symptom severity). Optimal doses are generally determined using experimental models and/or clinical trials. In some embodiments, the optimal dose depends upon the body mass, weight, or blood volume of the patient.
Oral doses typically range from about 1.0 mg to about 1000 mg, one to four times, or more, per day.

In some embodiments disclosed herein is a method for treating a cardiovascular disease, disorder or condition in a mammal in need thereof, comprising administering to the mammal in need thereof a therapeutically effective amount of a compound of Formula (III), or a pharmaceutically acceptable salt or solvate thereof.
Also contemplated herein are combination therapies, for example, co-administering a disclosed compound and an additional active agent, as part of a specific treatment regimen intended to provide the beneficial effect from the co-action of these therapeutic agents. The beneficial effect of the combination includes, but is not limited to, pharmacokinetic or pharmacodynamic co-action resulting from the combination of therapeutic agents. Administration of these therapeutic agents in combination typically is carried out over a defined time period (usually weeks, months or years depending upon the combination selected). Combination therapy is intended to embrace administration of multiple therapeutic agents in a sequential manner, that is, wherein each therapeutic agent is administered at a different time, as well as administration of these therapeutic agents, or at least two of the therapeutic agents, in a substantially simultaneous manner.
Substantially simultaneous administration is accomplished, for example, by administering to the subject a single formulation or composition, (e.g., a tablet or capsule having a fixed ratio of each therapeutic agent or in multiple, single formulations (e.g., capsules) for each of the therapeutic agents. Substantially simultaneous administration is also accomplished by administering to the subject a new chemical entity that is comprised of disclosed compound bound through chemical bond or linker to one or more additional active agents. Sequential or substantially simultaneous administration of each therapeutic agent is effected by any appropriate route including, but not limited to, oral routes, intravenous routes, intramuscular routes, and direct absorption through mucous membrane tissues. The therapeutic agents are administered by the same route or by different routes. For example, a first therapeutic agent of the combination selected is administered by intravenous injection while the other therapeutic agents of the combination are administered orally. Alternatively, for example, all therapeutic agents are administered orally or all therapeutic agents are administered by intravenous injection.
In some embodiments, disclosed herein is a method of treating a disease, disorder or condition selected from:
Combination therapy also embraces the administration of the therapeutic agents as described above in further combination with other biologically active ingredients and non-drug therapies. Where the combination therapy further comprises a non-drug treatment, the non-drug treatment is conducted at any suitable time so long as a beneficial effect from the co-action of the combination of the therapeutic agents and non-drug treatment is achieved. For example, in appropriate cases, the beneficial effect is still achieved when the non-drug treatment is temporally removed from the administration of the therapeutic agents, perhaps by days or even weeks.
The components of the combination are administered to a patient simultaneously or sequentially. It will be appreciated that the components are present in the same pharmaceutically acceptable carrier and, therefore, are administered simultaneously. Alternatively, the active ingredients are present in separate pharmaceutical carriers, such as conventional oral dosage forms, that are administered either simultaneously or sequentially.

Therapeutic effects of compound of Formula (I) or (Ia) or (Ib) or (Tc) or (II) or (III), called further the development candidate, will be demonstrated in a randomized, double-blind, parallel group, active control trial in patients with heart failure with preserved ejection fraction (HFpEF) according to the literature (Lancet 2012; 380: 1387-95).
The trial will include participants aged ≥40 years old with left ventricle ejection fraction (LVEF) ≥45% and a documented history of heart failure with associated signs or symptoms (dyspnea on exertion, orthopnea, paroxysmal dyspnea, and peripheral edema). Patients will be required:
Patients are excluded if they had previous LVEF <45% at any time, isolated right heart failure because of pulmonary disease, dyspnea because of noncardiac causes, such as pulmonary disease, anemia, or severe obesity, primary valvular or myocardial diseases, or coronary artery or cerebrovascular disease needing revascularization within 3 months of screening or likely to need revascularization during the trial.
Patients who fulfilled the criteria for enrolment will be randomly assigned (1:1) to treatment with either the development candidate or valsartan, using a central interactive voice response system. The treatments will be identical in appearance. Study investigators and participants were masked to treatment for the duration of the trial.
The double-blinded design will continue for 36 weeks, encompassing a 12-week main study period and 24-week extension period.
The primary study endpoint will be a change from baseline in N-terminal pro-B-type natriuretic peptide (NT-proBNP) assessed at 12 weeks. Secondary endpoints include changes in echocardiographic measures (left ventricular volumes and ejection fraction, left atrial volume, measures of diastolic function) and change in blood pressure, as well as change in New York Heart Association (NYHA) class, clinical composite assessment, and quality of life (Kansas City cardiomyopathy questionnaire; KCCQ).
NT-proBNP will be measured at screening, randomization, week 4, week 12, and week 36 or at end of study or at early termination visits. Assessment of NT-proBNP for efficacy will be measured at a central laboratory using a commercially available reagents (ex. Elecsys NT-proBNP immunoassay, Roche Diagnostics, Indianapolis, IN, USA).
Echocardiography will be done at screening, randomization, at week 12, and week 36 or at end of study or early termination visits. Measurements were made in triplicate in accordance with the recommendations of the American Society of Echocardiography.
The clinical composite assessment will be based on a composite of the NYHA functional classification, patient global assessment, and major adverse clinical events. Patients were classified as improved if at the endpoint visit they had improvement in NYHA functional classification or in patient global assessment (or both) but did not have a major adverse cardiovascular event. Patients will be assessed to be worse if at the endpoint visit they had a major adverse cardiac event during double-blind treatment or reported worsening of their NYHA class or patient global assessment.
The study size of 300 patients randomly assigned to two groups, ensures at least 80% power to detect a 25% reduction in the ratio of the 12-week NT-proBNP over baseline NT-proBNP between the development candidate group and the valsartan group, using a two-sided t test on the logarithm of this ratio, with an a level of 0.05. The calculation assumes a common SD of 0.83 for the log-scale of the ratio and a dropout rate of 10%. This sample size requires 132 patients completing the trial in each group.
