The present invention relates to a method comprising administering omega-3 fatty acid compositions for the reduction of fasting lipid parameters, such as triglycerides, total cholesterol, low density lipoprotein (LDL) cholesterol, free fatty acids, and other lipids. The present invention also relates to a method comprising administration of omega-3 fatty acid compositions for the increase of high density lipoprotein (HDL) cholesterol. The methods of the present invention may be useful of the treatment of a condition selected from the group consisting of: hypertriglyceridemia; hypercholesterolemia; mixed dyslipidemia; coronary heart disease (CHD); vascular disease; cardiovascular disease; acute coronary syndrome; atherosclerotic disease and related conditions; heart failure; cardiac arrhythmias; coagulatory conditions associated with cardiac arrhythmias; ischemic dementia; vascular dementia; hypertension; coagulation related disorders; nephropathy; kidney or urinary tract disease; retinopathy; cognitive and other CNS disorders; autoimmune diseases; inflammatory diseases; asthma or other respiratory disease; dermatological disease; metabolic syndrome; diabetes, diabetes mellitis or other form of metabolic disease; liver disease; non-alcoholic fatty liver disease; disease of the gastrointestinal tract; disease of the male or female reproductive system or related secondary sexual organs; a cancer of any type, including lymphomas and myelomas; an infection caused by a virus, bacterium, fungus, protozoa or other organism; and the treatment and/or prevention and/or reduction of cardiac events and/or cardiovascular events and/or vascular events and/or symptoms. The present invention also relates to treatment of such conditions in with concomitant treatments regimes or combination products with other active pharmaceutical ingredients.
In humans, cholesterol and triglycerides are part of lipoprotein complexes in the bloodstream, and can be separated via ultracentrifugation into high-density lipoprotein (HDL), intermediate-density lipoprotein (IDL), low-density lipoprotein (LDL) and very-low-density lipoprotein (VLDL) fractions. Cholesterol and triglycerides are synthesized in the liver, incorporated into VLDL, and released into the plasma. High levels of total cholesterol (total-C), LDL-cholesterol, and apolipoprotein B (a membrane complex for LDL-cholesterol and VLDL-cholesterol, as well as IDL-cholesterol in rare individuals suffering from a disorder resulting in significant IDL-cholesterol levels) promote human atherosclerosis; these elevated levels are often referred to as hypercholesterolemia. Decreased levels of HDL-cholesterol and its transport complex, apolipoprotein A, as well as elevated levels of apolipoprotein C-III and serum triglycerides (TG) are also associated with the development of atherosclerosis. Further, cardiovascular morbidity and mortality in humans can vary directly with the level of total-C, LDL-cholesterol and TG and inversely with the level of HDL-cholesterol. In addition, researchers have found that non-HDL-cholesterol is an important indicator of hypertriglyceridemia (elevated triglycerides), vascular disease, atherosclerotic disease and related conditions. Therefore, non-HDL-cholesterol and fasting TG reduction has also been specified as a treatment objective in NCEP ATP III. Fasting TG is commonly used as a key measure for TG in lipid management, because it minimizes the confounding factor of TG recently absorbed from meals, including the high variability of the content of meals and high variability of post-meal (post-prandial) spikes in TG. In some preferred embodiments, we refer to fasting TG levels when we refer to triglycerides or TG.
The NCEP ATPIII treatment guidelines identify HMG-CoA reductase inhibitors (“statins”) as the primary treatment option for hypercholesterolemia. In patients with TG<500 mg/dL, LDL-cholesterol is the primary treatment parameter. Many patients, however, have increased LDL-cholesterol combined with high TG and low HDL-cholesterol, a condition also known as mixed dyslipidemia. Patients with hypercholesteremia or mixed dyslipidemia often present with high blood levels of LDL-cholesterol (i.e. greater than 190 mg/dl) and TG (i.e. levels of 200 mg/dl or higher). The use of diet and single-drug therapy does not always decrease LDL-cholesterol and TG adequately enough to reach targeted values in patients with mixed dyslipidemia with or without a concomitant increase in triglycerides. In these patients, a combined therapy regimen of a statin and a second anti-dyslipidemic agent is often desired. This second agent has historically been a fibrate (i.e. gemfibrozil, bezafibrate, or fenofibrate) or extended release niacin. Over the few years, the use omega-3 fatty acid concentrates in combination with a statin has been growing rapidly due to concerns about the lack of outcome benefits with fibrates (i.e. the FIELD study) or extended release niacin (i.e. the AIM-HIGH study). In patients with isolated hypertriglyceridemia, the use of omega-3 fatty acid concentrates has also grown versus fibrates and extended release niacin.
Marine oils, also commonly referred to as fish oils, are a good source of the two main omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which have been found to regulate lipid metabolism. Omega-3 fatty acids have been found to have beneficial effects on the risk factors for cardiovascular diseases, especially mild hypertension, hypertriglyceridemia and on the coagulation factor VII phospholipid complex activity. Omega-3 fatty acids lower serum triglycerides (TG), increase serum HDL-cholesterol, lower systolic and diastolic blood pressure and the pulse rate, and lower the activity of the blood coagulation factor VII-phospholipid complex. Further, omega-3 fatty acids seem to be well tolerated, without giving rise to any severe side effects.
The table directly below lists the most common omega-3 fatty acids, including their 3-letter abbreviation code. In this application, the use of any of the 3-letter abbreviations shall refer to the omega-3 fatty acid, unless otherwise indicated (e.g. DPA or DPA 22:5 (n-3) or DPA 22:5-n3 or DPA 22:5n3 or DPA-n3, which all refer to the omega-3 isomer of docosapentaenoic acid).
One form of omega-3 fatty acids is a concentrate of omega-3, long chain, polyunsaturated fatty acids from fish oil containing DHA ethyl esters, EPA ethyl esters as well as ethyl esters of other omega-3 fatty acids (described in USP35 for LOVAZA®) and is sold under the trademarks OMACOR® and LOVAZA®. Such a form of omega-3 fatty acid comprises at least 90% omega-3 fatty acids of which at least 80% EPA+DHA (in a ratio of 1.2:1) and is described, for example, in U.S. Pat. Nos. 5,502,077, 5,656,667 and 5,698,594. LOVAZA® (omega-3-acid ethyl esters) is indicated for the treatment of patients with hypertriglyceridemia with TG levels of 500 mg/dL or higher.
Another form of omega-3 fatty acid concentrate is sold under the trademark EPADEL® ® for the treatment of dyslipidemia. This product is described as 98% EPA ethyl ester in Lancet (Vol. 369; Mar. 31, 2007; 1090-1098) reporting on a large outcome study with EPADEL®. EPADEL® is known to contain less than 1% of any fatty acid other than EPA.
Similar to EPADEL®, another form of omega-3 fatty acid concentrate also consists almost entirely of EPA ethyl ester and is known under its developmental stage name AMR101 or its trade name VASCEPA®. This product is described in US patent application 2010/0278879 as comprising at least 95% EPA (typically referred to as 97% or at least 96% in company releases and references) and less than 1% of any other fatty acid. AMR101 was previously under development for the treatment of Huntingdon's Disease but failed in phase III clinical development. Subsequently, AMR101 was entered in a development program for hypertriglyceridemia and mixed dyslipidemia.
Yet another concentrate of omega-3, long chain, polyunsaturated fatty acids from fish oil containing approximately 75% DHA and EPA as free fatty acids is known under its developmental stage name EPANOVA™. This product is described as comprising approximately 55% EPA and 20% DHA. EPANOVA™ was previously under development for the treatment of Crohn's Disease but failed in phase III clinical development. Subsequently, EPANOVA™ was entered in a development program for hypertriglyceridemia and mixed dyslipidemia.
Generally, the bioavailability and therapeutic effect of omega-3 fatty acid compositions is dose dependent, i.e., the higher the dose, the greater the therapeutic affect and bioavailability. However, the effect of each specific omega-3 fatty acid composition may be different, and therefore the level of therapeutic effect of one composition at a given dose cannot necessarily be inferred from the level of therapeutic effects of other omega-3 fatty acid compositions at the same or similar dose.
For instance, in the MARINE study, it was found that four 1-gram capsules of AMR101/VASCEPA® significantly reduced fasting TG in patients with very high triglycerides (TG>500 mg/dL) (March 2011, ACC poster reporting top-line results of the MARINE study), similar to four 1-gram capsules of LOVAZA® but in a less potent manner (LOVAZA® prescribing information, December 2010). In this same study, AMR101 slightly and non-significantly changed LDL-C while LOVAZA® shows a large significant increase in this same population, putting the latter at a disadvantage. Table A directly below compares these profiles.
In another study with AMR101/VASCEPA®, the ANCHOR study, it was found that four 1-gram capsules of AMR101 significantly reduced fasting TG in patients on statin therapy with high triglycerides (TG 200-499 mg/dL), similar to four 1-gram capsules of LOVAZA® but in a less potent manner (Study in table 3, LOVAZA® prescribing information, December 2010). In this same study, AMR101 decreased LDL-C at 4 gr/day while LOVAZA® shows a significant LDL-C increase in this same population. AMR101 is also more potent than LOVAZA® in reducing non-HDL-cholesterol in this population. Table B directly below compares these profiles.
The resulting lipid profile of AMR101 versus LOVAZA® in highly similar patient populations indicates that there are significant benefits of using an almost pure EPA oil composition as opposed to an omega-3 mixture as in LOVAZA®. These benefits translate into better non-HDL- and LDL-Cholesterol reduction with the pure EPA form, where these benefits are less or, in the case of the LDL-C effect, the opposite.
The recently released results from Omthera's EVOLVE trial with EPANOVA™, in patients with very high triglycerides (TG≧500 mg/dL), described a TG reduction of 31% versus baseline for the 4 gram per day dose and 26% versus baseline for the 2 gram per day dose, with 10% and 8% non-HDL reduction respectively. It appears that the TG-reducing potency of EPANOVA™ is similar to the potency of AMR101. No data were reported by Omthera on the LDL-C effect in the EVOLVE trial.
The recently released results from Omthera's ESPRIT trial with EPANOVA™, in patients with high triglycerides (TG 200-499 mg/dL) while on statin therapy, described a TG reduction of 21% versus baseline for the 4 gram per day dose and 15% versus baseline for the 2 gram per day dose, with 7% and 4% non-HDL reduction respectively. It appears that the TG-reducing potency of EPANOVA™ is similar to the potency of AMR101. No data were reported by Omthera on the LDL-C effect in the ESPRIT trial.
From the comparison of LOVAZA® versus AMR101 data, there appears to be a benefit of using pure EPA concentrates for dyslipidemia treatment over omega-3 mixtures with regard to LDL-Cholesterol and non-HDL-cholesterol effects. With the NCEP ATP III guidelines placing LDL-cholesterol and non-HDL-cholesterol reduction at the top of the treatment hierarchy for patients with TG<500 mg/dL, AMR101 is clearly superior to LOVAZA® in this patient category.
In another example, in the ECLIPSE Study, the bioavailability of EPANOVA™ is compared to LOVAZA® under high fat meal and low fat meal dosing conditions.
In the ECLIPSE study it is found that EPANOVA™ is significantly more bioavailable than LOVAZA® after single dose administration (four capsules of 1 gram for both products), both by Cmax (maximum concentration) and AUC (area under curve) measures (see Table C below, where Cmax and AUC are estimated from the data points in
Omega-3 fatty acids are known to be “essential fatty acids”. There are two series of essential fatty acids (EFAs) in humans. They are termed “essential” because they cannot be synthesized de novo in mammals. These fatty acids can be interconverted within a series, but the omega-6 (n-6) series cannot be converted to the omega-3 series nor can the omega-3 (n-3) series be converted to the omega-6 series in humans. The main EFAs in the diet are linoleic acid of the omega-6 series and alpha-linolenic acid of the omega-3 series. However, to fulfill most of their biological effects these “parent” EFAs must be metabolised to the other longer chain fatty acids. Each fatty acid probably has a specific role in the body. The scientific literature suggests that particularly important in the n-6 series are dihomo-gammalinolenic acid (DGLA, 20:3-n6) and arachidonic acid (ARA, 20:4-n6), while particularly important in the n-3 series are eicosapentaenoic acid (EPA, 20:5-n3) and docosahexaenoic acid (DHA, 22:6-n3).
U.S. Pat. No. 6,479,544 describes an invention in which it is found that ARA is highly desirable rather than undesirable and it may be helpful to administer ARA in association with EPA. This invention provides pharmaceutical formulations containing eicosapentaenoic acid or any appropriate derivative (hereinafter collectively referred to as EPA) and arachidonic acid (ARA), as set out in the granted claims for this patent. ARA may be replaced by one or more of its precursors, DGLA or GLA. In this reference, the ratio of EPA to ARA is preferably between 1:1 and 20:1.
Patent application PCT/GB 2004/000242 describes the treatment or prevention of psoriasis with a formulation comprising more than 95% EPA and less than 2% DHA. In another embodiment of this invention the EPA is replaced with DPA.
Patent application PCT/NL 2006/050291 (WO/2007/058538, GB 0301701.9) describes combinations of idigestible oligosaccharides and long chain poly-unsaturated fatty acids such as ARA, EPA, DA, and combinations thereof to improve intestinal barrier integrity, improving barrier function, stimulating gut maturation and/or reducing intestinal barrier permeability.
Lindeborg et al. (Prostag Leukotr Ess, 2013, 88:313-319) discloses a study evaluating postprandial metabolism of docosapentaenoic acid (DPA) and eicosapentaenoic acid (EPA) in humans.
Holub et al. (Lipids, 2011, 46:399-407) discloses a study assessing the effect of oral supplementation with docosapentaenoic acid (DPA) on levels of serum and tissue lipid classes and their fatty acid compositions in rat liver, heart, and kidney.
Given the highly beneficial efficacy and side-effect profile of omega-3 fatty acid concentrates, these compositions are increasingly popular for the treatment of patients with dyslipidemias. However, with the increased popularity of omega-3 fatty acid concentrates, there is an unmet medical need for omega-3 fatty acid containing compositions with improved bioavailability and a more optimal ratio of potency in reducing TG versus the resulting cholesterol profile. Specifically, agents with both a higher potency than AMR101/EPADEL® and lesser increase in LDL-C or further decrease in LDL-C and non-HDL-C than LOVAZA® are required.
Fasting triglyceride levels have been found to be correlated with the risk of cardiovascular diseases and conditions. For example, high fasting triglycerides levels have been associated with an increased risk of myocardial infarction. Gaziano et al. (Circulation, 1997; 96:2520-2525) discusses fasting triglyceride levels as a risk factor for coronary heart disease. Love-Osborne et al. (Pediatr Diabetes, 2006: 7:205-210) discloses the role of elevated fasting triglyceride levels in the development of type 2 diabetes mellitus.

In yet other embodiments, the fatty acid percentage is determined not as a percentage of all fatty acids present in the composition but as a specific type of glycerol fatty acid ester as percentage of all glycerol fatty acid esters present in the composition, thus excluding from the fatty acid percentage determination such fatty acids present as, for instance: fatty acid ethyl esters; free fatty acids; or fatty acids present in phospholipids (such as phosphatidylserine or phosphatidylcholine) or polysorbates (such as Tween 80, Tween 20, or polysorbate 40).
In further embodiments, the fatty acid percentage is determined not as a percentage of all fatty acids present in the composition but as di- or tri-fatty acid esters with glycerol as percentage of all glycerol di- and tri-fatty acid esters present in the composition, thus excluding from the fatty acid percentage determination such fatty acids present as, for instance: glycerol-mono-fatty acid esters; fatty acid ethyl esters; free fatty acids; or fatty acids present in phospholipids (such as phosphatidylserine or phosphatidylcholine) or polysorbates (such as Tween 80, Tween 20, or polysorbate 40).
In yet other embodiments, the fatty acid percentage is determined not as a percentage of all fatty acids present in the composition but as a tri-fatty acid esters with glycerol as percentage of all glycerol tri-fatty acid esters present in the composition, thus excluding from the fatty acid percentage determination such fatty acids present as, for instance: mono- and di-fatty acid esters of glycerol; fatty acid ethyl esters; free fatty acids; or fatty acids present in phospholipids (such as phosphatidylserine or phosphatidylcholine) or polysorbates (such as Tween 80, Tween 20, or polysorbate 40).
The EPA, HPA, DPA, or omega-3-pentaenoic acids may be derived from any appropriate source including plant seed oils, microbial oils from algae or fungal or marine oils from fish or other marine animals. Certain species are a particular good source of oils containing DPA, for example seal oil. They may be used in the form of the natural oil, if that oil meets the required purity requirements of the present invention, or may be purified to give products containing the fatty acid composition of the present invention.
The compositions of the present invention may be produced through a range of the methods. Such methods may include: distillation, including short path distillation; urea precipitation; enzymatic conversion concentration; conventional chromatography; HPLC/FPLC; supercritical carbondioxide extraction; supercritical carbondioxide chromatography; simulated moving bed chromatography; supercritical carbondioxide simulated moving bed chromatography; or chemical conversion methods such as iodolactonization. Such methods are generally known to those skilled in the art of purifying and isolating omega-3 fatty acids.
Typically, the omega-3 fatty acid concentration/purification process is initiated by esterifying the fatty acids comprised by the marine oil raw material (such as crude fish oil) with ethanol (to form fatty acid ethyl esters) in order to separate omega-3 fatty acids from other fatty acids covalently bound together in the natural triglyceride molecules of the source oil. Subsequently, the material may be distilled once or several times to achieve omega-3-acid ethyl ester concentrations above 60%-70%. Alternatively, enzymatic concentration, urea precipitation or supercritical extraction may be used alone or in conjunction with distillation to reach omega-3 levels above 70%-90%. In order to prepare a highly pure concentrate of a single omega-3 fatty acid, methods such as chromatography, supercritical chromatography, simulated moving bed chromatography, supercritical simulated moving bed chromatography, or chemical conversion methods such as iodolactolization are typically most practical to reach levels above 50%, alternatively above 60%, alternatively above 70%, alternatively above 80%, alternatively above 90%, alternatively above 95%, of a single omega-3 fatty acid such as ETA, EPA, HPA, DPA, TPA, or DHA.
Those skilled in the art will be able to design processes suited to prepare a certain omega-3 fatty acid composition as desired, based on the methods described above. Such processes are flexible enough to affect the relative proportions between the long chain C18, C20, C21 and C22 fatty acids which occur naturally in available fish oil raw materials and other marine oils. It provides not only for the concentration of the individual omega-3 fatty acids, but the ratio between them will remain within a pattern of variation caused by variations in nature. However, suitable methods compensate for sometimes extreme variations which may occur naturally. Thus, for those skilled in the art, it will be possible to make a product with a constant and predetermined composition.
EPA is relatively abundant in fish oils or other marine oils and can be relatively easy obtained through the application of concentration and purification technologies from such fish or marine oils. DPA and HPA are present at much lower concentrations. In order to prepare the compositions of the present invention, DPA or HPA may be concentrated and purified from fish or other marine oils according to the methods referred to above, either alone or DPA combined with EPA and/or HPA. Alternatively, the DPA or HPA may be chemically prepared from a high purity EPA concentrate by elongation of the EPA fatty-acid chain with two or one hydrogen-saturated carbons (C2-elongation or C1-elongation) on the carboxyl side of the molecule (for instance with a method similar to or alternate methods with equivalent results such as described by Kuklev DV and Smith WL in Chem Phys Lipids, 2006; 144(2): 172-177). In another alternative approach, a high purity EPA concentrate may be partially converted to DPA (or HPA) using a method for C2-elongation (or C1-elongation) of EPA similar to those described above, thus directly yielding compositions of the present invention or intermediates therefore.
Once the oils containing one or more of the desired fatty acids have been obtained, and purified as necessary, these oils may be blended to give the desirable relative amounts of EPA, DPA, HPA, DHA, TPA, other omega-3 fatty acids and omega-6 fatty acids to obtain the compositions of the present invention described in detail above.
Fish oils may also contain by-products and contaminants such as pesticides, chlorinated or brominated hydrocarbons, heavy metals, cholesterol and vitamins. During the production of the concentrate, the concentrations of these components are significantly reduced compared to untreated fish oils. Such reduction is inherent due to the nature of purification methods and their ability to concentrate of several or specific omega-3 fatty acids, thus removing other compounds.
Triglycerides comprising more than 60% of the omega-3 fatty acids in the composition may be produced from ethyl esters and glycerol by well known, published, or alternative chemical synthetic or enzymatic procedures. The free acids may be produced from ethyl esters by well known hydrolization or saponification procedures. Methods for converting ethyl esters to triglycerides, free fatty acids, and other molecular forms comprising fatty acids, are generally known to those skilled in the art chemically or enzymatically converting omega-3 fatty acids from one form to another.
In some embodiments, the compositions of the present invention have improved pharmacological features as demonstrated by improved bioavailability in a mammal of EPA, HPA, DPA, DHA, EPA+DHA, EPA+DPA or EPA+HPA+DPA combined, total omega-3-pentaenoic acids, or of total omega-3 fatty acids. Key parameters for determining bioavailability are maximum concentration of a therapeutic compound or a metabolite thereof (Cmax); the time from administration to maximum concentration (Tmax); and the area under the concentration curve over time (AUC). Such parameters may be determined under single dose or multiple dose administration regimens. Methods to determine comparative bioavailability in mammals are generally known to those skilled in the art. When comparing Tmax, Cmax, and AUC for embodiments of the present invention to LOVAZA®, EPANOVA™, and AMR101 throughout this application, such comparison will be on the basis of an equal dose of 4 capsules of 1 gram each for each of these products. The comparative parameters, however, do apply to all essentially equivalent dosing modes comparing embodiments of the present invention to LOVAZA®, EPANOVA™, and AMR101.
Meal conditions during administration to a subject of omega-3 fatty acid compositions or omega-3 fatty acid formulations are of special significance for absorption and bioavailability of omega-3 fatty acids. The meal conditions typically considered are: fasting (no food at all prior for 8-12 hours prior to administration and 2-3 hours post administration of the treatment); a low fat meat (a meal typically containing less than 25 gram of fat [350-600 Kcal] consumed just before or after the administration of the treatment; typically within a 15-30 minute range); or a high fat meat (a meal containing 40 gram to 75 gram of fat [700-1000 Kcal] consumed just before or after the administration of the treatment; typically within a 15-30 minute range).
In some embodiments of the present invention, compositions of the present invention are more rapidly absorbed as measured by the time to reach the maximum concentration (Tmax) in blood, serum or plasma of EPA, DPA, DHA, EPA+DPA, EPA+DHA, total omega-3-pentaenoic acids, or total omega-3 fatty acids. In preferred embodiments of the present invention, Tmax under high fat meal administration conditions is less than 8 hours, alternatively less than 6 hours, alternatively approximately 5 hours, alternatively 4 hours or less.

Methods to determine comparative blood/serum/plasma lipid and lipoprotein levels and therapeutic effects on these levels in mammals are generally know to those skilled in the art and are typically based on fasting lipid and lipoprotein levels. Differences of active treatment versus placebo are generally assessed on a group of subjects versus another group of subjects basis, with significant changes noted if the p-value for the appropriate statistical comparison is equal to or less than 0.05.

The present invention also provides methods of reducing triglycerides levels in a subject, wherein the non-HDL cholesterol levels, such as LDL-cholesterol levels, of the subject are reduced or not significantly increased from, for example, baseline levels before treatment. In some embodiments, treatment with the compositions of the present invention results in a minor (less than 10% change from baseline, alternatively less than 5%) and/or non-significant change in non-HDL cholesterol levels (such as LDL-cholesterol levels) as compared to placebo in patients with baseline TG levels above 500 mg/dL.

In another embodiment, the compositions of the present invention are more potent than other omega-3 compositions known in the prior art (such as LOVAZA®, EPANOVA™ or AMR101) in increasing as compared to placebo or baseline HDL-cholesterol levels, apolipoprotein-A levels, or a combination thereof.

In some embodiments, the use of the compositions of the present invention may allow for a reduction in the dose of the statin required for a subject. For example, the coadministration of the composition of the present invention in a subject receiving statin therapy may allow for the reduction of the dose of the statin, compared to subject not being co-administered a composition of the present invention. In some embodiments, the dose of the statin may be reduced by at least 10%, alternatively at least 25%, alternatively at least 50%, or alternatively at least 75%.
In some embodiments, the use of the compositions of the present invention may reduce the time needed for a subject to reach the recommended blood levels. For example, the administration of compositions of the present invention may allow a subject to reach goal lipid levels, for example, those described in the NCEP ATP III Guidelines, or any levels recommended by a health care practitioner. In some embodiments, the reduction of time is greater than 5%, alternatively greater than 15%, alternatively greater than 25%, alternatively greater than 50%, and alternatively greater than 75%.
The compositions of the present invention are also useful to treat coronary heart disease (CHD), vascular disease, atherosclerotic disease or related conditions. The compositions of the present invention may also be use for the treatment and/or prevention and/or reduction of cardiac events and/or cardiovascular events and/or vascular events and/or symptoms. Determination of such cardiovascular diseases/conditions and prevention of events/symptoms in mammals and methods to determine treatment and preventative/therapeutic effects therefore are generally know to those skilled in the art.
The present invention also relates to treatment of such conditions in with concomitant treatments regimes or combination products with other active pharmaceutical ingredients. Such concomitant or fixed combination treatments may include a statin, an anticoagulant (such as aspirin or clopidogrel), an antihypertensive (such as a diuretic, beta-blocker, calcium channel blocker, ACE-inhibitor, angiotensin II receptor (ARB) antagonist), or other treatments for cardiovascular diseases.
The present invention also includes pharmaceutical compositions, for example, a unit dosage, comprising one or more HMG-CoA reductase inhibitors (“statins”) and the omega-3 fatty acid composition of the present invention. The present invention may incorporate now known or future known statins in an amount generally recognized as safe. There are currently seven statins that are widely available: atorvastatin, rosuvastatin, fluvastatin, lovastatin, pravastatin, pitavastatin, and simvastatin. An eight statin, cerivastatin, has been removed from the U.S. market at the time of this writing. However, it is conceivable to one skilled in the art that cerivastatin may be used in conjunction with some embodiments of the present invention if cerivastatin is ultimately determined to be safe and effective in certain treatment regimens. Such statins are typically used at their common daily doses, which include, but are not limited to lovastatin 10 mg, 20 mg, 40 mg; pravastatin 10 mg, 20 mg, 40 mg, 80 mg; simvastatin 5 mg, 10 mg, 20 mg, 40 mg, 80 mg; fluvastatin 20 mg, 40 mg, 80 mg; atorvastatin 10 mg, 20 mg, 40 mg, 80 mg; rosuvastatin 5 mg, 10 mg, 20 mg, 40 mg; and pitavastatin 1 mg, 2 mg, 4 mg, 8 mg.
Generally, the effect of statins is dose dependent, i.e., the higher the dose, the greater the therapeutic affect. However, the effect of each statin is different, and therefore the level of therapeutic effect of one statin cannot be necessarily be directly correlated to the level of therapeutic effects of other statins. For example, bioavailability varies widely among the statins. Specifically, it has been shown that simvastatin is less than 5% bioavailable, while fluvastatin is approximately 24% bioavailable. Statins are absorbed at rates ranging from about 30% with lovastatin to 98% with fluvastatin. First-pass metabolism occurs in all statins except pravastatin. Pravastatin is also the least protein-bound of the statins (about 50%), compared with the others, which are more than 90% protein-bound. Accordingly, the statins possess distinct properties from one another. The combination products of this invention involving each statin or a plurality of statins are also distinct.
The present invention also includes methods of treatment, comprising dosing of one or more statins and the omega-3 fatty acid composition of the present invention, either as concomitant therapy or in a fixed dose combination product comprising both a statin and the composition of the present invention. This method of treatment combines the administration of one or more statins at its common dose or an alternative dose with the composition of the present invention.

Flavourants or emulsifiers may be included, for instance, to make the preparation palatable. Other conventional additives, diluents and excipients may be present. The preparation for ingestion may be in the form of a capsule, a dry powder, a tablet, a solution, an oil, an emulsion or any other appropriate form. The capsules may be hard or soft gelatin capsules, agar capsules, or any other appropriate capsule.
Use of the formulations of the invention in the manufacture of a medicament for the treatment or prevention of any disease or disorder, including those mentioned above, is included in the present invention.
The omega-3 fatty acid composition optionally includes chemical antioxidants, such as alpha tocopherol, which are administered in pure form or suspended in a vegetable oil, such as soybean oil or corn oil.
The blended fatty acid compositions may then be incorporated into any appropriate dosage form for oral, enteral, parenteral, rectal, vaginal, dermal or other route of administration. Soft or hard gelatin capsules, flavoured oil blends, emulsifiers or other liquid forms, and microencapsulate powders or other dry form vehicles are all appropriate ways of administering the products.
The formulated final drug product containing the omega-3 fatty acid composition may be administered to a mammal or patient in need thereof in a capsule, a tablet, a powder that can be dispersed in a beverage, or another solid oral dosage form, a liquid, a soft gel capsule or other convenient dosage form such as oral liquid in a capsule, as known in the art. In some embodiments, the capsule comprises a hard gelatin. The combination product may also be contained in a liquid suitable for injection or infusion.
Example pharmaceutical grade finished dosage forms: (a) Soft or hard gelatin capsules each containing 500 mg or 1000 mg of a mix 20 parts of EPA as a free fatty acid to 1 parts of DPA as a free fatty acid; (b) As in (a) but where the EPA and DPA free fatty acids are replaced with the fatty acids in any other appropriate bioassimilable form such as the ethyl esters; (c) As in (a)-(b) but where the material is in the form of a microencapsulated powder which can be used as a powder or compressed into tablets. Such powders may be prepared by a variety of technologies known to those skilled in the art; (d) As in (a)-(b) but where the formulation is a liquid or emulsion, appropriately flavoured for palatable oral administration; (e) As in (a)-(b) but where the material is formulated into a pharmaceutically acceptable vehicle appropriate for topical application such as a cream or ointment.
The omega-3 compositions of the present invention may also be administered with a combination of one or more non-active pharmaceutical ingredients (also known generally herein as “excipients”). Non-active ingredients, for example, serve to solubilize, suspend, thicken, dilute, emulsify, stabilize, preserve, protect, color, flavor, and fashion the active ingredients into an applicable and efficacious preparation that is safe, convenient, and otherwise acceptable for use. Thus, the non-active ingredients may include colloidal silicon dioxide, crospovidone, lactose monohydrate, lecithin, microcrystalline cellulose, polyvinyl alcohol, povidone, sodium lauryl sulfate, sodium stearyl fumarate, talc, titanium dioxide and xanthum gum.
The term “pharmaceutically acceptable vehicle,” as used herein, includes any of the following: a solution where the first API and optional other ingredients are wholly dissolved in a solubilizer (e.g., a pharmaceutically acceptable solvent or mixture of solvents), wherein the solution remains in clear liquid form at about room temperature; a suspension; an oil; or a semi-solid, wherein the first API and optionally other ingredients are dissolved wholly or partially in a solubilizer (an emulsion, cream, etc.).
A “pharmaceutical grade finished dosage form” as used herein may be construed as a unit dose form suitable for administration to, for example, human or animal subjects, and having content uniformity acceptable to regulatory authorities. For example, under the USP requirements for content uniformity, a pharmaceutical grade finished dosage form should have an amount of API within the range of 85% to 115% of the desired dosage and an RSD less than or equal to 6.0%. In addition, a pharmaceutical grade finished dosage form must be stable (i.e., have a “shelf life”) for a pharmaceutically acceptable duration of time, preferably at least six months, alternatively at least one year, or at least two years, when stored at room temperature (about 23 degree Celcius to 27 degree Celcius, preferably about 25 degree Celcius) and 60% relative humidity. Typically, stability is determined by physical appearance and/or chemical modification of the ingredients, in accordance with standards well-known in the pharmaceutical arts, including those documented in ICH guidelines.
The omega-3 fatty acid dosage form optionally includes chemical antioxidants, such as alpha tocopherol, oils, such as soybean oil and partially hydrogenated vegetable oil, and lubricants such as fractionated coconut oil, lecithin and a mixture of the same.

The following is an example of an embodiment of the present invention.
A mixture of DPA and EPA was prepared by combining 1 g DPA Ethyl Ester (SE-133-III) with 10 g EPA Ethyl Ester, 914 mg/g (KD Pharma FM13001) in 150 ml of 95% ethanol/water containing 35 ml of 2M sodium hydroxide. This reaction mixture was stirred overnight at ambient temperature. Tlc analysis showed complete conversion of the ethyl esters to the corresponding acids. The reaction mixture was cooled in an ice bath, acidified with 6N hydrochloric acid and concentrated on a rotavap under reduced pressure. Water and ethyl acetate were added, the phases separated and the aqueous residue extracted with ethyl acetate. The ethyl acetate extracts were combined, dried over sodium sulfate and concentrated to dryness on a rotavap under reduced pressure. Yield: 9.83 g. The ethyl ester mixture was then converted to the free fatty acids as described in example 7.
A representative sample of this ethyl ester composition was analysed using split inject by capillary gas chromatography by a 30 meter×0.25 mm Restek Stabil wax column using temperature programming.
The following describes a study conducted to determine the effect of compositions of the present invention.
An n-3 Pentaenoic testing batch containing roughly 85% EPA, 8% DPA, and 1% HPA was used to study pharmacodynamic effects in the Charles River Zucker fa/fa non-diabetic rat (strain code 185), which is known to display characteristics of insulin resistance, glucose intolerance, hyperinsulinemia, obesity and dyslipidemia. VASCEPA© is also used as a comparator. Male, eight to nine week old animals were used, with eight rats (n=8) per group. At the initiation of daily dosing, all animals were placed on chow+0.5% cholesterol diet (D13022002: Research Diets, New Brunswick, N.J.). Corn oil was used as a diluent for the omega-3 compounds, and methylcellulose to prepare the statin (atorvastatin) for dosing. A separate group of animals receiving corn oil alone was used as the untreated control group. Animals received daily doses of respective solutions by oral gavage. The study was conducted in 2 phases. In the first phase, the n-3 Pentaenoic composition and VASCEPA© solution is administered at 200 mg/kg, 400 mg/kg, and 1000 mg/kg. Animals were dosed daily for 14 days. For reference, a rat dose of 400 mg/kg would be equivalent to a human daily dose of approximately 4 grams (as shown in Reagan-Shaw et al. “Dose translation from animal to human studies revisited,” FASEB J. 22, 659-661 (2007), which is incorporated by reference in its entirety).
The second phase was initiated on day 15, with the groups receiving the n-3 Pentaenoic composition and VASCEPA© 400 mg/kg solution being co-administered statin at 10 mg/kg. Another group, previously dosed with corn oil vehicle, received atorvastatin to serve as an appropriate control. This second phase consisted of 14 days of daily, oral administration.
Plasma total cholesterol, LDL, HDL, triglycerides and VLDL were measured in the fasting state on day 0, 7 and 14; and for those groups included in the second phase on days 21 and 28. Levels of lipid parameters were determined in a 96-well multiplexed system using standard clinical chemistry techniques. Non-HDL cholesterol was calculated by subtracting the HDL value from the total cholesterol value. In addition, for the groups included in the second phase, insulin levels were determined at day 28.
Expression of genes for HMGCoA (3-hydroxy-3-methylglutaryl-coenzyme A; key regulatory enzyme for new cholesterol biosynthesis), PCSK9 (pro-protein convertase subtilisin kexin 9; associated with LDL receptor functioning and increased levels of LDL), and SREB-2 (sterol regulatory enhancing binding protein 2; regulates transcription of a wide variety of genes involved with new cholesterol synthesis) are evaluated in liver from groups included in the second phase. The mRNA (messenger RNA) was isolated from samples previously frozen at −70° Cs, and cDNA (complementary DNA) is derived for further study using standard molecular biology technique. Samples and corresponding probes for genes of interest are loaded onto a Life Science TLDA card. The level of gene expression was quantified using real time RT-PCR (reverse transcriptase polymerase chain reaction) and calculated using the ΔΔCt technique relative to the vehicle group in accordance to methodology recommended and as described by Applied Biosystems (Guide to Performing Relative Quantitation of Gene Expression Using Real-Time Quantitative PCR).
The following describes a study to determine the effect of compositions of the present invention.
STUDY #2—Humans
The overall pharmacokinetics of one of COMPOSITION 1a, 1b, 2, 3, or 4 are evaluated versus a reference compound after administration under fasting or fed conditions in normal, mostly healthy volunteers in a standard, 4-way cross-over trial design format. VASCEPA®, EPANOVA™, LOVAZA®, or EPADEL® are used as a reference compound. A total of 48 subjects are separated into 2 groups of 24. Each subject serves as his or her own internal control for comparison purposes under this 4-way crossover design. Inclusion criteria for tested subjects include volunteers between ages 18-65, with a BMI of 30-35 (alternatively a BMI of 27-35) and triglyceride levels less than 350 mg/dL, who consume no more than 1 fish meal per week and who are not currently prescribed pharmaco-therapy for lowering triglycerides, including but not limited to fibrates, omega-3 agents, and niacin. Volunteers on stable anti-hypertensive, anti-diabetic and thyroid therapy re allowed for consideration. Any person on stable statin therapy is considered if their triglyceride levels are less than 350 mg/dL. However, the total composition of subjects in the study with this particular profile is limited to no more than 30%.
Volunteers self-administering omega-3 non-prescription dietary supplements are asked to refrain from their use 2 weeks prior to the initiation of the study until study completion.
Pharmacokinetic Study #2 Design
The effect of oral administration of the compounds tested in this study is evaluated under fed versus fasting administration conditions, in order to determine drug pharmacokinetics, as well as to understand the effects of food on drug pharmacokinetics. COMPOSITION 1a or 1b or the reference compound are dosed at approximately 4 grams/day in the morning by administration of 4 capsules containing approximately 1 gram of each compound. Several days prior to pharmacokinetic evaluations, volunteers are housed at the testing facility in order to ensure well-controlled experimental conditions.
Compounds are given to volunteers following an overnight fast, with plasma samples obtained prior to dosing and at various time points after day 1 and day 14 dosing. Volunteers are allowed access to water, and well-defined meals at certain times. Afterwards, compound administration is stopped for a 2-4 week washout period, and the groups are switched with respect to which compound they would receive, meaning that the group initially receiving COMPOSITION 1a or 1b is switched to receive the reference compound, and vice versa. Fasting pharmacokinetics are determined using the procedure described above. Following completion of the second 14-day dosing cycle, compound dosing is stopped for a 2-4-week washout period prior to the initiation of the a similar cycle as above, now with COMPOSITION 1a or 1b and the reference compound are administered together with a meal.
Plasma levels of omega-3 fatty acids of interest from the study are determined utilizing an analytical LC/MS technique under GLP laboratory conditions in order to determine Cmax, Tmax and AUC for the omega-3 fatty acids of interest, including EPA, DPA, HPA, DHA, and other omega-3 fatty acids.
Results
The results of the study show that COMPOSITION 1a or 1b has a better bioavalability (as measured by AUC and Cmax) than the reference compound. This effect is seen under fasting and/or fed administration conditions.
In an alternate study design, this Study #2 is conducted with a certain dose level of COMPOSITION 2, COMPOSITION 3, or COMPOSITION 4 instead of COMPOSITION 1.
The following describes a study (STUDY #3) to determine the effect of compositions of the present invention.
A Multi-Center, Placebo-Controlled, Randomized, Double-Blind, 12-Week Study to Evaluate the Efficacy and Safety of COMPOSITION 1a, 1b, 2, 3 or 4 in Patients With Fasting Triglyceride Levels ≧500 mg/dL and ≧2000 mg/dL:
This Phase 3, multi-center study consists of a 6- to 8-week screening/washout period (to include a diet and lifestyle stabilization period), which includes a fasting triglyceride (TG) qualifying period of 2-3 weeks, followed by a 12-week double-blind treatment period. Patients on statin therapy (with or without ezetimibe) at screening are evaluated by the investigator as to whether this therapy could be safely discontinued at screening, or if it is to be continued. Patients on any other dyslipidemia therapy need to discontinue these in order to qualify for the study. If statin therapy (with or without ezetimibe) is to be continued, dose(s) must be stable for 4 weeks prior to the fasting TG baseline qualifying measurements for randomization. The screening visit is to occur at either 6 weeks before randomization for patients not on lipid-altering therapy at screening or for patients who do not need to discontinue their current dyslipidemia therapy, or at 8 weeks before randomization for patients who require washout of their current dyslipidemia therapy at screening.
The population for this study is men and women >18 years of age with a body mass index (BMI) ≧45 kg/m2. Patients on lipid-lowering therapy and patients not on lipid-lowering therapy are eligible to enroll in the study. Patients had to have an average TG level ≧500 mg/dL and ≦2000 mg/dL during the screening period to be eligible for randomization.
After confirmation of qualifying fasting TG values, eligible patients will enter a 12-week randomized, double-blind treatment period. At Week 0, patients will be randomly assigned to 1 of the following treatment groups: COMPOSITION 1a or 1b (approximately 2 g daily), COMPOSITION 1a or 1b (approximately 3 g daily), COMPOSITION 1a or 1b (approximately 4 g daily), or placebo. The daily dose may be taken as either a single dose or distributed over two doses per day.
Approximately 80 patients per treatment group will be randomized in this study. Stratification will be by baseline fasting TG level (≦750 mg/dL or >750 mg/dL, gender, and the use of statin therapy at randomization. During the double-blind treatment period, patients return to the site at Week 4, Week 11, and Week 12 for efficacy and safety evaluations.
The primary objective of the study is to determine the efficacy of COMPOSITION 1 at a approximately 2 g daily dose, approximately 3 g daily dose and approximately 4 g daily dose, compared to placebo, in lowering fasting TG levels in patients with fasting TG levels ≧500 mg/dL and ≦2000 mg/dL
The secondary and exploratory objectives of the study are as follows:

This multi-center study consists of a 4- to 6-week screening and washout period (to include a diet and lifestyle stabilization period, and to wash-out any non-statin/ezetimibe dyslipidemia medications), which also includes a 2-3 week fasting triglyceride (TG) level qualifying period, followed by a 6- to 12-week double-blind treatment period. Patients on statin therapy (with or without ezetimibe) at screening are evaluated by the investigator as to whether this therapy does maintain low-density lipoprotein (LDL) levels of ≧40 mg/dl and <100 mg/dl. At screening, statin therapy (with or without ezetimibe) is to be initiated, in those patients who are not on statin therapy in order to achieve LDL levels of ≧40 mg/dl and <100 mg/dl. Dose(s) of statin therapy must be stable for ≧4 weeks prior to the TG baseline qualifying measurements for randomization.
The population for this study is men and women >18 years of age with a body mass index (BMI) ≦45 kg/m2. Patients on lipid-lowering therapy and patients not on lipid-lowering therapy are eligible to enroll in the study.

In an alternate study design, this Study #4 is conducted with one or more dose levels of COMPOSITION 2, 3, or 4 instead of COMPOSITION 1a or 1b. In an alternative study design, Study #4 is conducted, enrolling patients with a baseline triglyceride level of about 300 to 499 mg/dL or about 350 too 400 mg/dL, instead of 200 to 499 mg/dL.
The following describes a study (STUDY #5) to determine the effect of compositions of the present invention.
The impact on fasting triglyceride levels and other pharmacodynamic endpoints of one of COMPOSITION 1a, 1b, 2, 3, or 4 are evaluated versus a reference compound after administration under fasting or fed conditions in normal, mostly healthy volunteers in a standard, 4-way cross-over trial design format. VASCEPA®, EPANOVA™ LOVAZA®, or EPADEL® are used as a reference compound. A total of 48 subjects are separated into 2 groups of 24. Each subject serves as his or her own internal control for comparison purposes under this 4-way crossover design. Inclusion criteria for tested subjects include volunteers between ages 18-65, with a BMI of 30-35 (alternatively a BMI of 27-35) and triglyceride levels less than 350 mg/dL, who consume no more than 1 fish meal per week and who are not currently prescribed pharmaco-therapy for lowering triglycerides, including but not limited to fibrates, omega-3 agents, and niacin. Volunteers on stable anti-hypertensive, anti-diabetic and thyroid therapy re allowed for consideration. Any person on stable statin therapy is considered if his or her triglyceride levels are less than 350 mg/dL. However, the total composition of subjects in the study with this particular profile is limited to no more than 30%.
Volunteers self-administering omega-3 non-prescription dietary supplements are asked to refrain from their use 2 weeks prior to the initiation of the study until study completion. Subjects using any other non-steroidal anti-inflammatory agents other than acetaminophen are asked to abstain and switch to acetaminophen for relief of pain, or are excluded from study consideration. Subjects are excluded if they receive any type of hormone therapy, weight loss agents, HIV therapy, beta-blockers, or are diagnosed with known cardiovascular disease, including heart failure, arrhythmia, any incidence of acute coronary syndrome, myocardial infarct, coronary artery bypass graft surgery, and/or angioplasty.
STUDY #5 Design
The effect of oral administration of the compounds tested in this study is evaluated under fed versus fasting administration conditions, in order to determine drug pharmacodynamics and effects on lipids. COMPOSITION 1a or 1b or the reference compound are dosed at approximately 4 grams/day in the morning by administration of 4 capsules containing approximately 1 gram of each compound.
Compounds are given to volunteers following an overnight fast, with plasma samples obtained prior to dosing on day 1 and day 14 dosing. Volunteers are allowed access to water, and well-defined meals at certain times. Afterwards, compound administration is stopped for a 2-4 week washout period, and the groups are switched with respect to which compound they would receive, meaning that the group initially receiving COMPOSITION 1a or 1b is switched to receive the reference compound, and vice versa. Following completion of the second 14-day dosing cycle, compound dosing is stopped for a 2-4-week washout period prior to the initiation of the a similar cycle as above, now with COMPOSITION 1a or 1b and the reference compound are administered together with a meal.
Baseline plasma levels of fasting serum triglycerides are determined on day 1 and just prior to initiation and completion of either the fasting or fed multi-dosing period. Additional lipid and other parameters (see below under “Results”) that are analyzed included total cholesterol, LDL, HDL, VLDL, non-HDL, and NEFA as previously described.
Effects on platelet function, such as clotting time and PAF-induced aggregation are also determined. Standard physiological, plasma and urinary safety markers, including but not limited to electrolytes, ALT, AST, BUN, glucose, blood pressure, weight etc. are monitored in accordance with standard good clinical trial guidelines.
Results
The results of the study show that COMPOSITION 1a or 1b has a better fasting triglyceride lowering effect than the reference compound. This effect is seen under fasting and/or fed administration conditions. Administration of COMPOSITION 1a or 1b have a beneficial effect, versus baseline and versus the reference compound, on other lipid parameters (such as HDL cholesterol, total cholesterol, non-HDL cholesterol, VLDL cholesterol), on platelet function, and one or more of the following: apolipoprotein A-I (apo A-I), apolipoprotein B (apo B), apo A-I/apo B ratio, lipoprotein(a) (Lp[a]), lipoprotein-associated phospholipase A2 (Lp-PLA2), low density lipoprotein (LDL) particle number and size, oxidized LDL, C-reactive protein (CRP), high sensitivity C-reactive protein (HSCRP), intracellular adhesion molecule-1 (ICAM-1), E-selectin, P-selectin, vascular cell adhesion molecule 1 (VCAM-1) or cluster of differentiation 106 (CD106), interleleukin-1β (IL-1g), interleukin-2 (IL-2), interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10), interleukin-12 (IL-12), interleukin-15 (IL-15), interleukin-18 (IL-18), tumor necrosis factor-alpha (TNF-α), tumor necrosis factor-beta (TNF-β), plasminogen activator inhibitor-1 (PAI-1), homocysteine, thromboxane B2 (TXB2), thromboxane A2 (TXA2), 2,3-dinor thromboxane B2, free fatty acids (FFA), serum amyloid A1, serum amyloid A2, serum amyloid A3, serum amyloid A4, thiobarbituric acid (TBA) reacting material, adiponectin (GBP-28), hemoglobin A1c (HbA1c), macrophage colony stimulating factor (M-CSF), granulocyte macrophage colony stimulating factor (GM-CSF), fibrinogen, fibrin D-dimer, platelet derived-microparticles, mean platelet volume (MPV), platelet subpopulations, heart rate, systolic and diastolic blood pressure, nuclear factor kappa-light-chain enhancer of activated B cells (NF-κβ), adenosine diphosphate induced platelet aggregation, platelet endothelial cell adhesion molecule (PECAM-1), vitronectin receptor (αvβv), and glycoprotein IIb/IIIa (gpIIIb/IIIa). This effect is more beneficial than that observed with VASCEPA®. Administration of COMPOSITION 1 has a beneficial impact, or a minimal impact, or no impact, on other non-HDL lipid parameters, such as LDL cholesterol versus baseline and the reference compound. In an alternate study design, this Study #5 is conducted with a certain dose level of COMPOSITION 2, 3, pr 4 instead of COMPOSITION 1a or 1b.
