Description

PRIORITY CLAIM
• This application claims priority to U.S. Provisional Patent Application No. 61/747,667, filed on Dec. 31, 2012, the entire contents of which are incorporated herein by reference and relied upon.
BACKGROUND
• Nonalcoholic steatohepatitis (“NASH”) is characterized by fat, inflammation and damage in the liver in people who consume little or no alcohol. NASH can lead to liver cirrhosis. NASH tends to be diagnosed in overweight or obese middle-aged people who often have elevated blood lipid levels and diabetes or prediabetes. Primary biliary cirrhosis (“PBC”) is characterized by inflammation and damage to the bile ducts. PBC is believed to be an autoimmune condition, but is more common in people who have been exposed to chemicals or who have had an infection. However, the causes of NASH and PBC are not well understood. There are no specific approved therapies for NASH, and only one approved drug for treatment of PBC. A need exists for improved treatments for NASH and PBC.
SUMMARY
• In various embodiments, the present invention provides methods of treating and/or preventing NASH and/or PBC in a subject and, in particular, a method of treating and/or preventing NASH and/or PBC in a subject comprising administering to a subject in need thereof a pharmaceutical composition comprising eicosapentaenoic acid (“EPA”) or a derivative thereof. In one embodiment, a pharmaceutical composition comprising about 1 to about 6 g of EPA or derivative thereof is administered to the subject daily. In one embodiment, the composition contains not more than 20% or not more than 10%, by weight, docosahexaenoic acid or derivative thereof, substantially no docosahexaenoic acid or derivative thereof, or no docosahexaenoic acid or derivative thereof. In another embodiment, eicosapentaenoic acid ethyl ester comprises at least 96%, by weight, of all fatty acids present in the composition; the composition contains not more than 4%, by weight, of total fatty acids other than eicosapentaenoic acid ethyl ester; and/or the composition contains about 0.1% to about 0.6% of at least one fatty acid other than eicosapentaenoic acid ethyl ester and docosahexaenoic acid (or derivative thereof).
• In one embodiment, a pharmaceutical composition useful in accordance with the invention comprises, consists of or consists essentially of at least 95% by weight ethyl eicosapentaenoate (EPA-E), about 0.2% to about 0.5% by weight ethyl octadecatetraenoate (ODTA-E), about 0.05% to about 0.25% by weight ethyl nonadecapentaenoate (NDPA-E), about 0.2% to about 0.45% by weight ethyl arachidonate (AA-E), about 0.3% to about 0.5% by weight ethyl eicosatetraenoate (ETA-E), and about 0.05% to about 0.32% ethyl heneicosapentaenoate (HPA-E). In another embodiment, the composition is present in a capsule shell. In another embodiment, the composition contains substantially no or no amount of docosahexaenoic acid (DHA) or derivative thereof such as ethyl-DHA (DHA-E).
• In another embodiment, the invention provides a method of treating moderate to severe hypertriglyceridemia comprising administering a composition as described herein to a subject in need thereof one to about four times per day.
• These and other embodiments of the present invention will be disclosed in further detail herein below.

Also disclosed herein are any and all ratios (and ranges of any such ratios) that can be formed by dividing a disclosed numeric value into any other disclosed numeric value. Accordingly, the skilled person will appreciate that many such ratios, ranges, and ranges of ratios can be unambiguously derived from the numerical values presented herein and in all instances such ratios, ranges, and ranges of ratios represent various embodiments of the present invention.
• In one embodiment, the invention provides a method for treatment and/or prevention of NASH and/or PBC in a subject and, in particular, a method of treating and/or preventing NASH and/or PBC in a subject comprising administering to a subject in need thereof a pharmaceutical composition comprising eicosapentaenoic acid or a derivative thereof.
• In some embodiments, the subject also has a cardiovascular-related disease. The term “cardiovascular-related disease” herein refers to any disease or disorder of the heart or blood vessels (i.e. arteries and veins) or any symptom thereof. Non-limiting examples of cardiovascular-related disease and disorders include hypertriglyceridemia, hypercholesterolemia, mixed dyslipidemia, coronary heart disease, vascular disease, stroke, atherosclerosis, arrhythmia, hypertension, myocardial infarction, and other cardiovascular events.
• The term “treatment” in relation a given disease or disorder, includes, but is not limited to, inhibiting the disease or disorder, for example, arresting the development of the disease or disorder; relieving the disease or disorder, for example, causing regression of the disease or disorder; or relieving a condition caused by or resulting from the disease or disorder, for example, relieving, preventing or treating symptoms of the disease or disorder. The term “prevention” in relation to a given disease or disorder means: preventing the onset of disease development if none had occurred, preventing the disease or disorder from occurring in a subject that may be predisposed to the disorder or disease but has not yet been diagnosed as having the disorder or disease, and/or preventing further disease/disorder development if already present.
• In one embodiment, the present invention provides a method of treating and/or preventing NASH and/or PBC, the method comprising administering to a subject or subject group in need thereof a pharmaceutical composition as described herein. In some embodiments, the subject or subject group has one or more of: an elevated baseline alanine aminotransferase (“ALT”) level, an elevated baseline aspartate aminotransferase (“AST”) level, liver fibrosis, an elevated baseline gamma-glutanyl transferase level, an elevated baseline alkaline phosphatase level, an elevated baseline antimitochondrial antibody level, an elevated baseline antinuclear antibody level, an elevated total serum bilirubin level, and an elevated transaminase level. In some embodiments, the subject is orally administered about 2 g to about 4 g per day of a pharmaceutical composition comprising at least about 90%, by weight of all fatty acids present, ethyl eicosapentaenoate. In another embodiment, the subject is administered about 2 to about 4 capsules per day, each capsule comprising about 900 mg to about 1.1 g of ethyl eicosapentaenoate. In one embodiment, the capsule contains not more than about 20% docosahexaenoic acid or its esters, by weight of all fatty acids present.
• Farnesoid X receptors (“FXR”), also referred to as bile acid receptor (“BAR”) or NR1H4 are known to be expressed in liver, intestine, kidney and adrenal tissues. Activated FXR translocates to the cell nucleus and forms a heterodimer with retinoid X receptor (“RXR”). The dimer binds to hormone response elements on DNA causing, among other effects, a suppression of cholesterol 7 alpha-hydroxylase (“CYP7A1”), the rate-limiting enzyme in bile acid synthesis from cholesterol, and stimulation of intestinal bile acid binding protein (“IBABP”). Both CYP7A1 and IBABP are involved in homeostatis of bile acid and cholesterol. Bile acids such as chenodeoxycholic acid (“CDCA”), lithocholic acid (“LCA”) and deoxycholic acid (“DCA”) are known to act as agonists of FXR. In one embodiment, the present invention provides a method of inhibiting FXR (e.g., agonizing) in a mammal, the method comprising administering to mammal a pharmaceutical composition as described herein. In some embodiments, the mammal has one or more of: an elevated baseline alanine aminotransferase (“ALT”) level, an elevated baseline aspartate aminotransferase (“AST”) level, liver fibrosis, an elevated baseline gamma-glutanyl transferase level, an elevated baseline alkaline phosphatase level, an elevated baseline antimitochondrial antibody level, an elevated baseline antinuclear antibody level, an elevated total serum bilirubin level, and an elevated transaminase level. In some embodiments, the mammal is orally administered about 2 g to about 4 g per day of a pharmaceutical composition comprising at least about 90%, by weight of all fatty acids present, ethyl eicosapentaenoate. In another embodiment, the mammal is administered about 2 to about 4 capsules per day, each capsule comprising about 900 mg to about 1 g of ethyl eicosapentaenoate and not more than about 20% docosahexaenoic acid or its esters, by weight of all fatty acids present.
• Novosphingobium aromaticivoransis a gram-negative alphabacterium known to be strongly associated with PBC occurrence. The mechanism is not well understood, but appears to involve a cross reaction between the proteins of the bacterium and mitochondrial proteins of the liver cells. The gene encoding CD101 (cluster of differentiation 101, also referred to as immunoglobulin superfamily, member 2 or IGSF2) may also play a role in host susceptibility to PBC. In one embodiment, the present invention provides a method of inhibitingN. aromaticivoransin a mammal, the method comprising administering to mammal a pharmaceutical composition as described herein. In some embodiments, the mammal has one or more of: an elevated baseline alanine aminotransferase (“ALT”) level, an elevated baseline aspartate aminotransferase (“AST”) level, liver fibrosis, an elevated baseline gamma-glutanyl transferase level, an elevated baseline alkaline phosphatase level, an elevated baseline antimitochondrial antibody level, an elevated baseline antinuclear antibody level, an elevated total serum bilirubin level, and an elevated transaminase level. In another embodiment, the mammal is administered about 2 to about 4 capsules per day, each capsule comprising about 900 mg to about 1 g of ethyl eicosapentaenoate and not more than about 20% docosahexaenoic acid or its esters, by weight of all fatty acids present.
