FIELD OF INVENTION
The present invention relates to formulations and methods for the treatment or prevention of chronic liver disease such as alcohol or toxic chemical induced cirrhosis or fibrosis, chronic hepatitis C virus infection, and/or non-alcoholic steatohepatitis. In particular, the invention relates to antioxidant formulations optionally supplemented with additional formulations directed to the treatment of specific causes of chronic liver disease such as a hepatitis C virus infection and non-alcoholic steatohepatitis. The invention also relates to methods of treating chronic liver disease, in particular, methods of treating chronic liver disease using the formulations of the invention.
BACKGROUND OF THE INVENTION
Chronic liver disease is marked by the gradual destruction of liver tissue over time. Several liver diseases fall under this category, including cirrhosis and fibrosis, the latter of which is often the precursor to cirrhosis.
Cirrhosis is the result of acute and chronic liver disease and is characterized by the replacement of liver tissue by fibrotic scar tissue and regenerative nodules leading to a progressive loss of liver function. Fibrosis and nodular regeneration results in the loss of the normal microscopic lobular architecture of the liver. Fibrosis represents the growth of scar tissue resulting from, for example, infection, inflammation, injury, and even healing. Over time, the fibrotic scar tissue slowly replaces the normal functioning liver tissue resulting in a decreasing amount of blood flow to the liver leaving the liver incapable of fully processing nutrients, hormones, drugs, and poisons that are found in the bloodstream. More common causes of cirrhosis include alcoholism, hepatitis C viral infections, ingestion of toxins, and fatty liver, but many other possible causes also exist.
Chronic hepatitis C virus (HCV) infection and non-alcoholic steatohepatitis (NASH) are the two major causes of chronic liver disease in the United States estimated to affect between 3-5 million people. A rising concern is the continuously increasing number of U.S. citizens, currently numbering over 30 million, with obesity and metabolic syndrome that have non-alcoholic fatty liver disease (NAFLD) with approximately 10% who will eventually develop NASH.
Other bodily complications are a consequence of a loss of liver function. The most common complication of cirrhosis is a condition known as ascites, an accumulation of fluid in the peritoneal cavity, which can lead to an increased risk of spontaneous bacterial peritonitis possibly resulting in the premature death of the patient.
Other potentially life-threatening complications of cirrhosis include hepatic encephalopathy, a neuropsychotic abnormality resulting when toxic substances that normally are removed by the liver from blood begin to impair the proper functioning of brain cells. Hepatic encephalopathy manifests itself in a widely varying array of quantitative and qualitative distinct features, depending on the severity of impairment that occurs. The resulting cerebral dysfunction can be mild, manifesting itself through neuropsychiatric and psychomotor dysfunction, impaired memory, increased reaction time, sensory abnormalities and poor concentration. More severe manifestations resulting from hepatic encephalopathy include confusion, stupor, coma, and even eventual death. There are at least four theories for the pathogenesis of the condition. One theory suggests an energy failure in the cerebrum resulting from impaired glucose oxidative pathways caused by liver failure that leads to increased lactate synthesis in the brain. Another theory supports the notion of energy failure in the cerebrum but resulting instead from hypoglycemia and hypoxia caused by impaired liver function. A third theory suggests that the liver's failure to convert ammonia to urea or glutamine causes an increased concentration of the component in the bloodstream resulting in hyperammonemia in the brain eventually leading to the death of brain cells. A final theory for pathogenesis of hepatic encephalopathy is that any decrease in glucose utilization to provide energy to the brain is compensated for by the mobilization of amino acids that provide carbon skeletons as substrates for energy metabolism; however, the proteolysis of cerebral proteins to compensate for any energy loss ultimately proves destructive to proper functioning of the brain.
Yet another potentially life-threatening complication of cirrhosis includes esophageal varices or extremely dilated sub-mucosal veins in the esophagus that are susceptible to bleeding.
Once any cirrhosis or fibrosis has occurred in the liver, it is generally considered irreversible. Rather, conventional treatment focuses on preventing any further progression of cirrhosis in the liver and mitigating the complications that can arise from cirrhosis. In more advanced stages of cirrhosis, the only conventionally known treatment is a liver transplant.
The American Liver Foundation estimates that over 300,000 people in the United States are hospitalized each year as a result of cirrhosis of the liver. It is also estimated that 18,000 people are in need of liver transplants.
There remains a need in the art for a composition, formulation, and/or method of treatment for inhibiting fibrosis, preventing the development of cirrhosis, and possibly reversing development of the conditions altogether, which are responsible for many of the life-threatening complications associated with chronic hepatitis and chronic liver disease, such as, for example, excessive bleeding from esophageal varices, mental disturbances due to hepatic encephalopathy, ascites, liver cancer, and death due to exhaustion of liver function.
There remains a need in the art for a composition, formulation, therapy, and/or effective treatment to inhibit the progression of fibrosis in patients suffering from acute or chronic liver disease. There remains a further need in the art for a composition, formulation, therapy, or effective treatment to induce fibrosis reversal in patients suffering from acute or chronic liver disease. There remains a further need in the art for a composition, formulation, therapy or effective treatment to inhibit the progression of fibrosis and/or induce fibrosis reversal in patients suffering from acute or chronic liver disease that is substantially free of side effects.
HCV is a member of the hepacivirus genus of the Flaviviradae family of viruses. HCV can be classified into six genetic groups otherwise known as HCV clades that can further be classified into over 100 subtypes. The clades and subtypes differ from each other at the nucleotide level. Chronic hepatitis, experienced by well over 75% of persons infected, ultimately leads to cirrhosis of the liver in approximately 20% of those persons chronically infected and liver cancer leading to deaths of between 1% and 5% of those persons chronically infected. It is estimated that 3.5 million people have chronic hepatitis in the United States.
The pathogenesis of chronic HCV infection is associated with both a defective host antiviral immune response and an intrahepatic oxidative stress. Oxidative stress is possibly induced by the combined effects of an inflammatory response by the host and the HCV non-structural viral proteins. Additionally, oxidative stress and lipid oxidation are known to play a major role in fatty liver accumulation, which leads to necro-inflammation and necrosis of hepatic cells.
HCV non-structural viral proteins have been shown to cause activation of STAT-3 through oxidative stress and Ca2+ signaling. See Gong et al., “Human Hepatitis C Virus NS5A Protein Alters Intracellular Calcium Levels, Induces Oxidative Stress, and Activates STAT-3 and NF-kappa B,” Proc. Nat'l. Acad. Sci. USA, 98:9599-604 (2001). STAT-3 induction is influenced by the activation of cellular kinases, including p38 mitogen-activated protein kinase, JNK, JAK-2, and Src. In vivo experiments showed STAT-3 induction becomes inhibited in the presence of an antioxidant. It has been reported that HCV core protein increases radical oxygen species as well as products of lipid peroxidation and antioxidant gene expression. See Waris et al., “Hepatitis C Virus Constitutively Activates STAT-3 via Oxidative Stress: Role of STAT-3 in HCV Replication,” J. Virol., 79:1569-80 (2005). These processes are thought to contribute to fibrosis and carcinogenesis in hosts with chronic HCV infections. See Koike, “Molecular Basis of Hepatitis C Virus-Associated Hepatocarcinogenesis: Lessons from Animal Model Studies,” Clin. Gastroenterol Hepatol, 3:Sβ2-S135 (2005).
Fatty liver, also known as steatosis, is a disease that is characterized by an excessive amount of lipids accumulating in the liver. Fatty liver may develop due to medicine or alcohol use, viral or bacterial infections, or obesity. Fatty liver and conditions stemming from fatty liver include NASH, liver inflammation, cirrhosis, and liver failure. Steatohepatitis is inflammation of the liver resulting from fat accumulation in the liver.
NASH, also known as non-alcoholic fatty liver disease, is a hepatic disorder that is typically characterized by an alcoholic pathogenesis but without being influenced by alcohol consumption. Rather, NASH is directly related to the amount of fat in the liver. While there are many possible causes of NASH, the most likely causes that have been identified include obesity due to a poor diet, diabetes, long-term use of steroids, and the use of tetracycline. See, e.g., Bacon et al., “Nonalcoholic Steatohepatitis: An Expanded Clinical Entity,” Gastroenterology, 107:1103-91 (1994).
Recent studies have shown that oxidative stress and lipid peroxidation play a major role in fat accumulation in the liver, or steatosis, that leads to necroinflammation and necrosis of hepatic cells. Steatosis, and the ensuing lipid peroxidation, can lead to activation of stellate cells, the cells in the liver that are principally responsible for fibrogenesis. Some research has been directed towards identifying compositions comprising antioxidants that would be useful to treat the oxidative stress and/or lipid peroxidation associated with NASH.
Antioxidative therapy, directed towards mitigating the intrahepatic oxidative stress pathway, has been shown to have a beneficial effect on patients with chronic HCV infection. For example, U.S. Pat. No. 7,078,064 to Zabrecky discloses compositions having antioxidants that are useful for treating chronic liver disease, chronic hepatitis C virus infection, and non-alcoholic steatohepatitis. U.S. Pat. No. 6,069,167 to Sokol discloses the use of certain antioxidant agents including vitamin E, carotenoids, and selenium to treat cholestatic liver disease. U.S. Pat. No. 6,596,762 to Sokol discloses an antioxidant composition consisting of soluble vitamin E, mixed carotenoids, and selenium for the treatment of hepatic steatosis. These references report in vivo testing showing a high dosage of antioxidant administered to the subject relative to the subject's body weight. These references further show the administration therapies must be frequent and continue long-term.
The safety and efficacy of antioxidant therapy for patients with chronic HCV infection, in particular, for those patients who failed in interferon treatment has been reported in Gabby et al., “Antioxidant Therapy for Chronic Hepatitis C after Failure of Interferon: Results of Phase II Randomized, Double-Blind Placebo Controlled Clinical Trial,” World J. Gastroenterol., 13(4):5317-23 (2007). 100 patients suffering chronic HCV infection were enrolled in this double-blind, placebo controlled single-center trial. The study involved two treatment options involving 50 patients in each section. The first part tested the administration of oral and intravenous antioxidant preparations versus that of a placebo. The second part tested the administration of only the oral preparations versus a placebo. 25 patients were randomly assigned to each of the treatment group and the placebo group.

The data shows that the combined use of oral and intravenous antioxidant formulations only mildly alleviate the intra-hepatic inflammatory response in patients suffering a chronic HCV infection while no effect is shown by using only the oral antioxidant treatment.

There remains a need in the art for an antioxidant formulation that can be administered as part of a treatment therapy to effectively prevent, retard, and/or reverse the effects of a chronic liver disease. There remains a further need in the art for an antioxidant composition that can be administered as part of a treatment therapy for acute or chronic liver disease that is substantially free of side effects. There remains a further need in the art for an antioxidant composition that can be administered as part of a treatment therapy for acute or chronic liver disease that is affordable.
Conventionally, the treatment of chronic HCV is a combination therapy including pegylated interferons and ribavirin. However, the response rate of the treatment's pharmacological efficacy and adverse effects is approximately 55% in patients infected with the genotype I virus. See Hughes et al., “Chronic Hepatitis C Virus Management: 2000-2005 Update,” Ann. Pharmacother, 40:74-82 (2006).
There remains a need in the art for a therapy to treat chronic HCV infected patients, especially for those patients who are non-responsive to conventional treatment therapies.
The use of alternative medicine is common in patients with chronic liver disease. For example, compositions comprising antiviral active components derived from herbal medicinal plants have traditionally been used in China for the treatment of hepatitis B virus, HCV, and HIV. Indeed, many modern drugs contain ingredients that are derived from herbs. The more conventionally termed alternative medicine, traditionally known as “folk” medicine, involves the use of herbal medicines in the care and treatment of the sick. Alternative medicine strategies have become more accepted in the western scientific medical community particularly as the development of pharmaceutical compounds have failed to keep pace with the ever-growing knowledge of pathogenesis pathways of various viral infections and diseases.
In fact, it has come to be known that many traditional herbal formulations lead to an in vivo response that can produce the pharmacological ingredient leading to the desired host response to combat the infection or disease. For example, the Chinese herbal medicine Aeginetiae Herba has traditionally been used to treat, among other things, liver disease. Aeginaetiae Herba is prepared from the dried whole plant of Aeginetia indica. A phosphate buffered saline extract from the seeds of Aeginetia indica has been shown to exhibit excellent carcinostatic effect possessing interleukin 2 and interferon y inducing potency effect. The Chinese herbal medicine Scutellariae Barbatae Herba derived from dried whole plants of Scutellaria rivularis have traditionally been used for the treatment of hepatitis and liver cirrhosis. The traditional Chinese practice of prescribing herbal medicines was in response to symptoms of a patient typically after a disease or agent itself had progressed to more advanced stages of development in the patient.
A method of producing an interferon inducer from the plants of the genus Cucurbitaceae, such as from a pumpkin seed, is disclosed in U.S. Pat. No. 4,421,746 to Kojima et al. U.S. Pat. No. 4,456,597 to Kojima et al. discloses an antiviral and anti-tumor activity of interferon inducers that are extracted from the flowers of Carthamus tinctorious. U.S. Pat. No. 4,469,685 also to Kojima et al. discloses that interferon inducers useful for the treatment of viral infections in humans may be extracted from the flowers of Lonicera japonica and the seeds of Plantago asiatica. 
Traditional Chinese and Ayurvedic therapies or treatment strategies have focused on the use of herbal formulations having many components, but it is not entirely clear whether a single component within the formulation or the combination of a collection of components within the formulation are responsible for the medicinal or therapeutic benefit. However, it is duly noted, that such a concept does run counter to the traditional western medicine concept of pharmacological treatment, which is focused on the delivery of a single compound or drug for the treatment of an infection, condition, disease, and the like.
There remains a need in the art to explore and identify alternative medicine treatments, either used alone or in a complimentary treatment strategy, generally for patients suffering from cirrhosis of the liver and, specifically, for patients having a chronic liver disease.

Indeed, the alternative medicine treatment may be used in a complimentary treatment strategy administered to a subject suffering any condition that has caused chronic liver disease.
As used herein, the acronym “ALT” refers to alanine amino transferase, a diagnostic liver function test. The test is also known as serum glutamate pyruvate transaminase (SGPT) or alanine aminotransferase (ALAT). Consistently elevated levels of ALT may suggest the existence of, among other medical problems, alcoholic or viral hepatitis. ALT is typically measured in units/liter (U/l).
As used herein, the acronym “AST” refers to aspartate aminotransferase, an enzyme that catalyzes the transfer of the amino group from glutamic acid to oxaloacetic acid forming alpha-ketoglutaric acid and aspartic acid. Elevated levels of AST can be a sign of acute liver damage. AST is typically expressed in units/liter (U/l).
As used herein, the term “bilirubin” is a compound that is excreted in bile. The level of bilirubin becomes elevated with certain diseases, in particular hepatitis or severe liver failure with cirrhosis.
As used interchangeably herein, the terms “cirrhosis” and “liver cirrhosis” refers to any stage in the development of the pathological condition, for example, from the initial development of scar tissue in the liver to advanced stages of fibrosis. Non-limiting examples of diseases or conditions that are known to lead to cirrhosis include alcoholism; Type B or Type C chronic viral hepatitis; chronic bile duct blockage; Wilson's disease or hemochromatosis, a metabolic diseases resulting in unusually high levels of copper iron, respectively, being stored in the body. Other causes of cirrhosis include, but are not limited to, exposure to drugs or other toxins; autoimmune processes such as autoimmune hepatitis; diseases that are inherited such as cystic fibrosis and alpha antitrypsin deficiency; and obesity, which is also known as fatty liver or nonalcoholic steatohepatitis. Yet, even other causes of cirrhosis can include severe reactions to drugs; prolonged exposure to environmental toxins; parasitic infection schistosomiasis; and repeated incidents of heart failure with liver congestion.
The term “extract,” as used herein, means a substance or composition obtained from a plant or plant part. An extract may be composed of an exudate, i.e., a substance or composition found external to the plant or plant part; internal to the plant or plant part, but external to the cells of the plant or plant part; and/or within the cells of the plant or plant part. Chemical and/or physical action or actions, as understood in the art, are required to obtain an extract from a plant or plant part.
As used herein, the acronym “HAI” refers to Knodell histological activity index. HAI is a grading or scoring system for the assessment of liver damage and represents the summation of four individual scores reflecting periportal and/or bridging necrosis, intralobular degeneration and focal necrosis, portal inflammation, and fibrosis. HAI, as traditionally measured, ranges from 0-22. Modifications to the scoring system have been made in order to provide a more detailed assessment of, for example, fibrosis. A lower score represents little to no necrosis, inflammation, and/or fibrosis. Higher scores are intended to reflect that the liver has suffered more extensive damage.
As used herein, “HCV” refers to hepatitis C virus, which is a species of the hepacivirus genus of the Flaviviridae family of viruses.
The term “HCV active,” as used herein, means therapeutically or pharmacologically active for purposes of treating a condition associated with an acute or chronic HCV infection. Preferably, an “HCV active” will be therapeutically or pharmacologically active for purposes of retarding a fibrosis and/or cirrhosis occurring in the liver of a subject or a fibrosis and/or cirrhosis that would otherwise occur in the liver of a subject resulting from an acute or chronic HCV infection. Preferably, an “HCV active” will also be therapeutically or pharmacologically active for purposes of reversing a fibrosis and/or cirrhosis occurring in the liver of a subject resulting from an acute or chronic HCV infection.
As used herein, “NASH” refers to non-alcoholic steatohepatitis, a condition that resembles alcoholic hepatitis, but, rather, is inflammation of the liver due to fat accumulation.
The term “NASH active,” as used herein, means therapeutically or pharmacologically active for purposes of treating a condition associated with NASH. Preferably, a “NASH active” will be therapeutically or pharmacologically active for purposes of retarding a fibrosis and/or cirrhosis occurring in the liver of a subject or a fibrosis and/or cirrhosis that would otherwise occur in the liver of a subject resulting from NASH. Preferably, a “NASH active” will also be therapeutically or pharmacologically active for purposes of reversing a fibrosis and/or cirrhosis occurring in the liver of a subject resulting from NASH.
A “pharmaceutically acceptable carrier” as used herein refers to a non-toxic solid, semisolid or liquid filler, diluent, encapsulating material or formulation auxiliary of any conventional type. A “pharmaceutically acceptable carrier” is non-toxic to recipients at the dosages and concentrations employed, and is compatible with other ingredients of the formulation.
The term “pharmaceutically acceptable excipient” as used herein includes adjuvants, diluents, vehicles, or other auxiliary substances, such as those conventional in the art, which are readily available to the public. For example, pharmaceutically acceptable auxiliary substances include pH adjusting and buffering agents, tonicity adjusting agents, stabilizers, wetting agents and the like.
The term “pharmaceutically acceptable salt” as used herein is intended to mean a salt of a compound according to the invention that is, within the scope of sound medical judgment, suitable for use in contact with the tissue of a subject without at least one of undue toxicity, irritability, and allergic response, commensurate with a reasonable benefit to risk ratio and is effective for its intended use.
The terms “subject,” “host,” and “patient,” as used herein, are used interchangeably to refer to an animal that is being treated with the present formulations, including, but not limited to, simians, humans, avians, felines, canines, equines, rodents, bovines, porcines, ovines, caprines, mammalian farm animals, mammalian sport animals, and mammalian pets. In preferred embodiments of the invention, the “subject,” “host,” or “patient” is a human.
The term “therapeutically effective amount” or “effective amount” as used herein, means that amount of an active agent, a compound, a drug, or a formulation, that elicits a desired biological or medicinal response in a tissue system of a subject, or in a subject, that is being sought by a researcher, veterinarian, medical doctor or other clinician. In preferred embodiments of the invention, the tissue system of a subject is a liver. The desired response can include interdicting, preventing, palliating, or alleviating an existing viral infection or disease in the subject that is being treated. In some embodiments, the desired response includes at least a reduction in one or more symptoms, disorders, or diseases of a hepaciviral infection in the subject under treatment.
One skilled in the art will recognize that the “therapeutically effective amount” of an active agent, a compound, a drug, or a formulation to be used in the instant invention can vary with factors, such as the particular subject, e.g., age, weight, diet, health, etc.; severity and complications of viral infection condition sought to be treated or prevented; severity and complications of the chronic liver disease sought to be treated or prevented; the mode of administration of the active agent, the compound, the drug, or the formulation; the particular active agent, compound, drug, or formulation used, etc. Standard procedures can be performed to evaluate the effect of the administration of an active agent, a compound, a drug, or a formulation to a subject, thus allowing a skilled artisan to determine the effective amount of the active agent, a compound, a drug, or a formulation to be administered to the subject. For example, the syndrome or symptoms of the viral infection or disease, such as, for example, fever or inflammation, etc., the count of virus, ALT, AST, bilirubin, and the like, can be measured from the subject prior to or after the administration of the active agent, the compound, the drug, or the formulation. In addition, techniques, such as surveys or animal models, can also be used to evaluate the effectiveness of an active agent, a compound, a drug, or a formulation in treating or preventing a chronic liver disease.
The term “therapeutically effective amount of time” as used herein means the amount of time needed to elicit a desired biological or medicinal response in a tissue system of a subject, or in a subject, that is being sought by a researcher, veterinarian, medical doctor or other clinician. The desired response includes interdicting, preventing, palliating, or alleviating an existing infection, disease, or the like in the subject that is being treated. In some embodiments of the invention, the desired response includes at least a reduction in one or more symptoms, disorders, or diseases of an infection, disease, or the like in the subject under treatment. In preferred embodiments of the invention, the desired response includes retarding a fibrosis or cirrhosis occurring in the liver. In another preferred embodiment, the desired response includes reversing a fibrosis or cirrhosis occurring in the liver. One skilled in the art will recognize that the “therapeutically effective amount of time” to be used in the instant invention can vary with factors, such as the particular subject, e.g., age, weight, diet, health, etc.; severity and complications of viral infection, chronic liver disease, and/or condition sought to be treated or prevented; the mode of administration of the active agent; the particular active agent used; and the like.
The terms “therapy,” “treatment,” “treating,” and other like terms, as used interchangeably herein, refer to obtaining a desired pharmacologic and/or physiologic effect. The effect may be prophylactic in terms of completely or partially preventing a condition or disease or symptom thereof and/or may be therapeutic in terms of a partial or complete cure for a condition or disease and/or adverse affect attributable to the condition or disease. “Therapy” and/or “treatment,” thus, for example, covers any therapy and/or treatment of a condition or disease in a mammal, preferably in a human, and includes at least one of: (a) preventing the condition or disease or symptom thereof from occurring in a subject which may be predisposed to the condition or disease but has not yet been diagnosed as having it; (b) inhibiting the condition or disease or symptom thereof, such as, arresting its development; and (c) relieving, alleviating or ameliorating the condition or disease or symptom thereof, such as, for example, causing regression of the condition or disease or symptom thereof.
The term “vehicle”, as used herein refers to a non-toxic solid, semisolid or liquid filler, carrier, diluent, excipient, solubilizing agent, encapsulating material or formulation auxiliary of any conventional type, and encompasses all of the components of the composition other than the active pharmaceutical or active ingredient(s). Suitable vehicles include, but are not limited to, water, dextrose, glycerol, saline, ethanol, buffer, dimethyl sulfoxide, Cremaphor EL, and combinations thereof. The vehicle may contain additional agents such as wetting or emulsifying agents, or pH buffering agents.

Because evidence suggests that oxidative stress can have a role in the mechanisms leading to liver injury, preferably, the formulations of the invention will comprise at least one antioxidant that is useful for treating oxidative stress. More preferably, the at least one antioxidant can treat the oxidative stress associated with chronic liver disease caused by, for example, chronic HCV infection or NASH. Even more preferably, the inventive formulation comprises more than one antioxidant whose combined therapeutic effect is greater than the therapeutic effect provided by the individual use of any one of the antioxidants.
Glutathione is an antioxidant, antitoxin, and enzyme cofactor that naturally occurs in cells. Glutathione is synthesized by the liver and becomes involved in DNA synthesis and repair, protein and prostaglandin synthesis, amino acid transport, metabolism of toxins and carcinogens, immune system function, preventing oxidative cell damage, and enzyme activation. Glutathione is a powerful antioxidant that also recycles other antioxidants such as vitamin C and vitamin E allowing them to remain in an active state. Studies have shown that a treatment regimen including glutathione inhibits tumor necrosis factor-alpha (TNF-α) activity in subjects suffering from alcoholic hepatitis. See Hill et al., “Antioxidants Attenuate Nuclear Factor-Kappa B Activation and Tumor Necrosis Factor-Alpha Production in Alcoholic Hepatitis Patient Monocytes and Rat Kupffer Cells, in vitro,” Clin. Biochem., 32(7):563-70 (1999). Glutathione can be orally administered to a subject as L-glutathione, a pharmaceutically acceptable salt of glutathione.
N-acetyl cysteine is the N-acetyl derivative of the amino acid L-cysteine. N-acetyl cysteine is a precursor of glutathione but is, in many respects, a more efficient means of delivering glutathione to a subject. N-acetyl cysteine easily crosses a cell membrane, while glutathione cannot. Once N-acetyl cysteine has permeated the cell membrane, it is converted to cysteine and then to glutathione. Therefore, while reactive oxygen species such as hydrogen peroxide and hydroxyl-free radicals reduce intracellular and extracellular concentrations of glutathione, N-acetyl cysteine effectively replenishes glutathione and reduces any damage caused by these reactive oxygen species. N-acetyl cysteine, if taken alone, can have an irritating effect on the mucous membrane in the stomach and has an extremely bad taste. Further, N-acetyl cysteine becomes rapidly degraded and excreted from the body. A frequent dosage regimen is required in order to maintain a reasonable concentration of N-acetyl cysteine in the blood stream.
Ascorbic acid or ascorbate, a pharmaceutically acceptable salt of ascorbic acid, also better known as vitamin C, is a water-soluble vitamin that has been used in the treatment of chronic hepatitis. Ascorbic acid is derived from glucose via the uronic acid pathway; however, the enzyme L-gulonolactone oxidase, which converts gulonolactone to ascorbic acid is absent in primates requiring that the vitamin be a part of the human diet. Vitamin C has been reported to enhance glutathione regeneration in plasma and impart hepatotoxicity. See Hargreaves et al., “Studies on the Effects of L-Ascorbic Acid on Acetaminophen-Induced Hepatotoxicity II. An in vivo Assessment in Mice of the Protection Afforded by Various Dosage Forms of Ascorbate,” Toxicol. Appl. Pharmacol., 64(3):380-92 (1982).
Ganoderma lucidum, or Reishi mushrooms, are polypore mushrooms that are renowned for their medicinal properties. These mushrooms only flourish mainly on the dried trunks of dead plum, guercus serrata, or pasonia trees; therefore, they are scarce and remain largely undiscovered in the West. The Chinese name is Lingzhi, which means “spiritual potency,” and has been recognized for over 2,000 years by Chinese medical professionals as a valuable remedy. A liquid fermentation broth of Ganoderma lucidum protected mice from hepatitis B virus activity. The study further showed that the cultured broth of Ganoderm lucidum supplemented with aqueous extract of Radix Sophorae flavescentis, a kind of Chinese herbal medicine, had better medicinal effects than simply mixing these two ingredients together. See Li et al., “Anti-Hepatitis Activities in the Broth of Ganoderma lucidum Supplemented with a Chinese Herbal Medicine,” Am. J. Chin. Med., 34(2):341-49 (2006).
Glycyrrhiza has been shown to be effective in treating patients suffering from a chronic HCV infection, in particular those patients who are not responsive to interferon therapy. See, e.g., Abe et al., “Effectiveness of Interferon, Glycyrrhizin Combination Therapy in Patients with Chronic Hepatitis C,” Nippon Rinsho., 52(7):1817-22 (1994). Glycyrrhizin can be extracted from the roots of licorice plants (Glycyrrhiza glabra). Licorice is important in traditional Chinese medicine (known as gancao, translated as “sweet grass” or “sweet herb”), and thus is extensively cultivated. While the exact mechanism is not clear, it has been proposed that glycyrrhizin has an inhibitory effect on immune mediated cytotoxicity against hepatocytes and on nuclear factor (NF)-kappa B, which activates genes encoding inflammatory cytokines in the liver.
Lipoic acid, also known as alpha-lipoic acid (α-lipoic acid), is a naturally occurring enzyme found in most prokaryotic and eukaryotic microorganisms as well as in plant and animal tissue. Lipoic acid's therapeutic potential has been recognized in conditions where oxidative stress is associated with liver damage. See Bustamante et al., “Alpha-Lipoic Acid in Liver Metabolism and Disease,” Free Radic. Biol. Med., 24(6):1023-39 (1998). Typically, only the R-enantiomer of lipoic acid occurs naturally. Indeed, more recent studies suggest that the S-enantiomer inhibits the effect of the R-enantiomer, substantially reducing its biological activity, increasing rather than reducing oxidative stress. Hence, embodiments of the invention that include α-lipoic acid will more preferably include R isomer α-lipoic acid or a racemic mixture wherein R isomer α-lipoic acid dominates over S isomer α-lipoic acid. See Loffelhardt et al., “Interaction of Alpha-Lipoic Acid Enantiomers and Homologues with the Enzyme Components of the Mammalian Pyruvate Dehydrogenase Complex,” Biochem. Pharmacol., 50(5): 637-46 (1995).
Oleanolic acid is a triterpenoid compound that exists widely in natural plants in the form of free acid or aglycones for triterpenoid saponins Oleanolic acid has been identified as a main bioactive constituent in many of the medicinal plans used in folk medicine. Oleanolic acid has been reported to demonstrate potent hepotoprotective activity. See, e.g., U.S. Pat. No. 6,884,908 to Srivastava et al.
Salvia miltiorrhiza, also known as Red sage, Chinese sage, tan shen, or dan shen, is a traditional Chinese medicinal herb used for the treatment of cardiovascular and hepatic diseases Salvia miltiorrhiza is a shade-growing perennial flowering plant in the genus Salvia. Seven phenolic compounds isolated from the aqueous extract of Salvia miltiorrhiza demonstrate a protective action against peroxidative damage to liver microsomes, hepatocytes, or erythrocytes. See Liu et al., “Protective Action of Seven Natural Phenolic Compounds Against Peroxidative Damage to Biomembranes”, Biochem. Pharmacol., 43(2):147-52 (1992).
Schisandra is derived from the berries that are harvested from Schisandra chinensis, a deciduous, dioecious woody vine that is a member of the Magnoliaceae family. Traditionally, schisandra has been distributed throughout northern and northeast China. The berries are harvested in the fall, dried, and ground for subsequent medicinal use. Studies have shown that schisandra protects the liver from lipid peroxidation or injury that is induced by carbon tetrachloride poisoning. See Liu, “Pharmacological Properties of Dibenzo [a, c] Cyclooctene Derivatives Isolated from Fructus Shisandra Chinensis III Inhibitory Effects on Carbon Tetrachloride-Induced Lipid Peroxidation, Metabolism and Covalent Binding and Carbon Tetrachloride to Lipids,” Chem. Biol. Interact., 41(1):39-47 (1982). Schisandra has been found to also be effective against viral and chemical induced hepatitis in subjects through certain mechanistic pathways, such as, lowering serum glutamic pyruvic transaminase (SGPT) levels, reducing ethanol induced malondialdehyde (MDA) formation, and increasing superoxide dismutase and catalase activities. Liu et al., “Effect of Dibenzo [a, c] Cycloocten Lignans Isolated from Fructus Shisandra on ADPH Induced Lipid Peroxidation (Malondialdehyde MDA) Formation) and Anti-Oxidative Enzyme Activity,” Chem. Biol. Interact., 78(1):77-84 (1991).
Silymarin is a mixture of three flavonolignans (silyban, silydianin, and silychristin) extracted from the seeds of the milk thistle plant Silybum marianum. Silymarin has been used as a Chinese and Ayurvedic medicine for well over 2,000 years. Additionally, Silymarin has notoriously been researched as a plant extract for the treatment of liver disease with over 450 publications addressing its use in such treatments. In particular, silybin or silibinin has been characterized as a hepato-protective substance. After ingesting silymarin and undergoing enterohepatic recirculation, high concentrations are found in liver cells. See Valnezuela et al., “Biochemical Bases of the Pharmacological Action of the Flavonoid Silymarin and of its Structural Isomer Silibinin,” Biol. Res., 27(2):105-12 (1994). Silymarin has also been shown to slow, or possibly reverse, liver fibrosis in animals. See Boigk et al., “Silymarin Retards Collagen Accumulation in Early and Advanced Biliary Fibrosis Secondary to Complete Bile Duct Obliteration in Rats,” Hepatology, 26:643-49 (1997).
Vitamin B-complex represents eight water soluble vitamins, each playing an important role in cell metabolism. Vitamin B-complex includes thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7 or H), folic acid (B9), and cyanocobalamin (B12) each bearing similar properties that mostly work together synergistically. The therapeutic effects of B vitamins for treating chronic hepatitis have been investigated. In particular, vitamin B12 has proven to be useful in treating hepatitis by becoming stored in high concentrations in the liver and becoming available to participate in the regulation of hepatotropic virus functions. Specifically, vitamin B12 has been found to inhibit, however, not through a competitive binding mechanism, the HCV internal ribosome entry site (IRES)-dependent translation of a reporter gene in vitro in a dose-dependant manner without significantly affecting the cap-dependent mRNA resulting in a normalizing effect on the level of ALT in the bloodstream. Takyar et al., “Vitamin B12 Stalls the 80 S Ribosomal Complex on the Hepatitis C Internal Ribosome Entry Site,” J. Mol. Biol., 319(1):1-8 (2002).
Vitamin E is a fat-soluble vitamin that collectively includes eight naturally occurring compounds designated as either tocopherols or tocotrienols. α-Tocopherol, a powerful biological antioxidant, is the most active form of vitamin E in humans. It is believed that Vitamin E protects against liver damage induced oxidative stress by normalizing liver enzymes. See Sun et al., “Evaluation of Oxidative Stress Based on Lipid Hydroperoxide, Vitamin C and Vitamin E During Apoptosis and Necrosis Caused by Thioacetamide in Rat Liver,” Biochim. Biophys.

Picrorhiza kurroa is a small plant that grows at high altitudes in the western Himalayas. Picrorhiza kurroa is a well-known herb in the Ayurvedic system of medicine that has traditionally been used to treat, among other things, disorders of the liver. Picrorhiza, which is the dried rhizome of the herb Picrorhiza kurroa, demonstrates the ability to inhibit the generation of oxygen anions and to scavenge free radicals. Kutkin, comprised of kutkoside and the iridoid glycoside picrosides I, II, and III, is the active principal of Picrorhiza kurroa. However, apocynin, a cathecol, has been isolated from Picrorhiza kurroa and shown to be an effective anti-inflammatory agent because of its ability to prevent the formation of free radicals, oxygen ions, and peroxides in the body. Drosin and nine cucurbiacin glycosides have also been identified as active constituents of Picrorhiza kurroa. 
While the hepatoprotective activity of Picrorhiza kurroa is not fully understood, it is believed to be attributed to the herb's ability to inhibit the generation of oxygen anions and to scavenge free radicals. Russo et al., “Indian Medicinal Plants as Antiradicals and DNA Cleavage Protectors,” Phytomedicine, 8:125-β2 (2001). A randomized, double-blind, placebo-controlled trial including patients diagnosed with acute viral hepatitis were administered 375 mg of Picrorhiza kurroa root powder tid over a two week period. Bilirubin, serum glutamic-oxaloacetic transaminase, and serum glutamic pyruvic transaminase values were significantly lower in the treatment group when compared to the response of the placebo group. See Vaidya et al., “Picrorhiza kurroa (Kutaki) Royle ex Benth as a Hepatoprotective Agent—Experimental and Clinical Studies,” J. Postgrad. Med., 42:105-108 (1996).
Baicalin is a flavonoid that has been shown to affect γ-aminobutyric acid receptors, which is the chief inhibitory neurotransmitter in the mammalian central nervous system. Baicalin has also been characterized as having good anti-inflammatory activity. Baicalin can be isolated, for example, from extracts of Scutellaria baicalensis. In passing through the gastrointestinal tract, baicalin is converted to baicalein, a therapeutically active form of baicalin. In those formulations of the invention that are administered parenterally, transdermally, or any other forms of administration that avoid the digestive tract, a preferred formulation comprises baicalein. In formulations described herein, the term “baicalin/baicalein” will be interpreted to mean any of baicalin, baicalein, and combinations thereof.
Matrine and oxymatrine is found in several varieties of herbs including extracts of the sophora genus. Oxymatrine, the oxide of matrine, is converted to matrine, in the gastrointestinal tract. Matrine is believed to be more readily soluble than oxymatrine, and has been found to possess many medicinal properties possibly including use as a treatment for viral hepatitis.

The bark from the Catalpa ovata, or the Chinese Catalpa, tree was used in traditional Korean medicine as an anti-inflammatory agent. A methanol extract of this folk medicine has been shown to inhibit the productions of tumor necrosis factor-alpha (TNF-alpha) and nitric acid (NO) with significant decreases in mRNA levels of TNF-alpha and inducible NO synthase showing the bark may have therapeutic potential in controlling inflammatory disorders, for example, such as those associated with NASH. Pa et al., “Inhibitory Effects of the Stem Bark of Catalpa ovata G. Don. (Bignoniaceae) on the Productions of Tumor Necrosis Factor-α and Nitric Oxide by the Lipopolisaccharide-Stimulated RAW 264.7 Macrophages,” J. Ethnopharmacol., 88: 287-91 (2003). U.S. Pat. Publ. No. 2006/0160898 discloses that catalpic acid, present in the seeds of catalpa trees, has also been found to be medicinally useful in treating and even preventing Type 2 diabetes and associated disorders.
Paeoniflorin is one of the main effective components of the total glucosides of paeony (TGP) that is extracted from the root of Paeonia lactiflora. The anti-inflammatory, antioxidative, antihepatic injury and immunoregulatory activities of TGP are known in the art. The administration of paeoniflorin has been shown to significantly decrease the serum ALT activities in mice induced with an immunological liver injury. The increase in TNF-alpha, lipopolysaccharide binding protein, and CD14 mRNA (messenger ribonucleic acid) expression in mouse liver was significantly decreased by paeoniflorin and was changed by paeoniflorin at different time-points after administering the compound. Liu et al., “Protective Effect of Paeoniflorin on Immunological Liver Injury Induced by Bacillus Calmette-Guerin plus Lipopolysaccharide: Modulation of Tumour Necrosis Factor-α and Interleukin-6 mRNA,” Clin. Exp. Pharmacol. Physiol., 33(4):332-39 (2006).
Berberine is a quaternary plant alkaloid from the group of isoquinoline alkaloids that is typically found in the roots, rhizomes, stems, and bark of such plants as Berberis, goldenseal (Hydrastis canadensis), and Coptis chinensis. Berberine has a long history of medicinal use in both Ayurvedic and Chinese medicine. It has been found that berberine hydrochloride attenuates hepatic fat degeneration of rats with fatty liver induced by a high-fat diet. Wang et al., “Effects of Berberine Hydrochloride on Nonalcoholic Fatty Liver Disease in Rats,” Journal of Lanzhou University (Medical Sciences), 33(4):8-11 (2007). The article stresses that decreased serum aminotransferase, triglyceride, low density lipid cholesterol, epididymal fat, and perirenal fat may be the result of improved insulin resistance.

EXAMPLES
A rodent model of spontaneous liver fibrosis progression and of established advanced fibrosis was used to demonstrate whether antioxidant formulations supplemented with either HCV-specific or NASH-specific supplemental formulations in a combination therapy could be used to retard the progression of liver fibrosis or reverse an established fibrosis.
Example 1
The purpose of this experiment was to test for the potential of an antioxidant formulation, either alone or in combination with an HCV-specific or a NASH-specific supplemental formulation, to impede the progression of ongoing liver fibrosis in a model if Mdr2 knockout mice.
Abcb4 is a human gene that is associated with progressive familial intrahepatic cholestasis whereby bile is prevented from flowing from the liver. Mdr2 (Abcb4)−/− mice have been characterized as developing progressive liver fibrosis. Mdr2−/− knockout and Mdr2+/+ wildtype mice were bred. Age-matched groups of Mdr2−/− mice of both sexes were treated during spontaneous progression of liver fibrosis from 4 weeks of age to 10 weeks of age. Mdr2−/− female mice are known to develop more severe lesions than males; hence, the analyses for mice in each gender were reported separately.
Six healthy wildtype mice undergoing no intervention constituted the control group. Four-week old Mdr2−/− knockout mice with early onset of biliary fibrosis were used in the treatment portion of the study. Forty-seven mice received a daily application of an antioxidant cocktail comprising the formulation and dose identified in Table 1 (“Prep-X”) in a 10 μl vehicle per g body weight by intragastic gavage. Mice receiving only the vehicle were used as the control group.

Fifteen mice (nine males and six females) continued the daily treatment for six weeks. Sixteen mice (seven males and nine females) continued the treatment daily for three weeks. Beginning with the fourth week of the treatment regimen, these sixteen mice continued to receive Prep-X supplemented with an HCV-specific supplemental formulation whose formulation and dose is shown in Table 1. This treatment continued daily for three additional weeks. Sixteen other mice (six males and nine females) continued the daily treatment for three weeks. Beginning with the fourth week of the treatment regimen, these sixteen mice continued to receive Prep-X supplemented with a NASH-specific supplemental formulation whose constituents and dose are shown in Table 1. This treatment continued daily for three additional weeks. At 10 weeks, the age when untreated mice progress into advanced interstitial (biliary-type) fibrosis, the mice were sacrificed by cardiac puncture and exsanguination under general anesthesia. The livers and spleens of the mice were excised, weighed, and snap-frozen in liquid nitrogen for further analysis. All the mice were housed with 12-hour light-dark cycles and fed with water and standard rat/mouse pellet chow ad libitum. Table 2 shows the relative and total hepatic collagen content of the livers and the weights of the liver and spleen for each of the groups of mice.

The procedure for determining hydroxyproline includes taking two snap-frozen liver pieces representing between 10-20% of total liver mass from the right and median liver lobe—approximately 250-300 mg total. These portions are hydrolyzed in 2 ml 6N hydrochloric acid at 110° C. for 16 hours. Hydroxyproline content was determine in 5 μl of hydrolysate biochemically in a 96-well plate format assay. More detailed procedures for determining hydroxyproline content can be found in Schuppan et al., “Lancet Seminars: Liver Cirrhosis,” Lancet, 371:838-51 (2008); Popov et al., “Mdr2 (Abcb4)−/− Mice Spontaneously Develop Sever Biliary Fibrosis vis Massive Dysregulation of Pro- and Antifibrogenic Genes,” J. Hepatol, 43:1045-54 (2005); and Popov et al., “Halofuginone Induces Matrix Metalloproteinases in Rat Hepatic Stellate Cells via Activation of p38 and NFkappaB,” J. Biol. Chem., 281:150980-98 (2006), all included herein by reference. Total hepatic hydroxyproline for each liver was determined by multiplying the weight of the liver by the relative hepatic hydroxyproline content determined above.

The statistical significance of the difference in data, expressed as means±standard error of mean, was evaluated using an unpaired, non-parametric Student's t-test with a probability of error, p-level, of 0.05 (hereinafter referred to as “t-test”). The t-test showed that the deviation of means between the following groups of samples were not statistically significant: relative collagen content for male mice, relative collagen content for female mice, total hepatic collagen content for female mice, liver weights for female mice, and spleen weight for female mice. On the other hand, the t-test showed that the deviation of means between the following groups of samples had statistical significance: total hepatic collagen content for male mice, liver weights for male mice, and spleen weight for male mice.
FIG. 1A is an image, with five times magnification, of a representative liver section of a male mouse using connective tissue staining after undergoing treatment receiving only the vehicle over a six week period. FIG. 1B is an image, with five times magnification, of a representative liver section of a male mouse using connective tissue staining after undergoing treatment receiving Prep-X over a six week period with the HCV-specific supplemental formulation included at the midway point of the combination treatment. FIG. 1C is an image, with five times magnification, of a representative liver section of a male mouse using connective tissue staining after undergoing treatment receiving Prep-X over a six week period with the NASH-specific supplemental formulation included at the midway point of the treatment. These figures show no apparent difference in periportal (or portal tract) collagen. However, lobular (parenchymal) collagen is reduced with a loss of fibrotic septa and the liver architecture is improved in the male mice receiving Prep-X over a six week period supplemented with the NASH-specific supplemental formulation at the midway point of the combination treatment, as shown in FIG. 1C.
Quantitative real-time reverse transcriptase-polymerase chain reaction (RT-PCR) results were obtained for each of the liver specimens. 150-200 mg liver tissues from two lobes were homogenized using a tissue homogenizer and total RNA was extracted using RNAPURETM reagent (manufactured by PeqLab of Erlangen, Germany) according to the manufacturer's recommendations. Template cDNA was obtained by reverse transcription of 1 μg of total RNA and relative transcript levels were quantified by real-time RT-PCR on a LIGHTCYCLER® 1.5 (manufactured by Roche of Mannheim, Germany). Probes and primers for mouse procollagen α1(1), TFGβ1, TIMP-1, α-SMA, and β2-microglobulin designed to span exon-exon boundaries to exclude genomic DNA co-amplification were used in the study. Housekeeping gene β2-microglobulin was amplified in parallel reactions for normalization. More details concerning the use of this procedure and these probes can be found in Schuppan et al. and the two references to Popov et al. as further recited herein.
FIGS. 2A-2D respectively represent profibrogenic gene expression of procollagen α1(1) encoding the major scar collagen; tissue inhibitor of matrix metalloproteinase-1 (“TIMP-1”); profibrogenic, proliferating cholangiocyte-associated integrin alpha v beta 6; and interstitial collagenase matrix metalloproteinase-13 (“MMP-13”). The quantitative real-time RT-PCR results are expressed in arbitrary units relative to the internal standard β2-microglobulin mRNA. The data are expressed as x-fold increase (mean±standard error of mean) versus the livers from the wildtype control mice. The t-test showed that the deviation of means for gene expression between the following groups of samples had statistical significance: procollagen α1(1) encoding the major scar collagen for the male mice and the female mice, TIMP-1 for the female mice, cholangiocyte-associated integrin alpha v beta 6 for the female mice, and interstitial collagenase MMP-13 for the female mice. The t-test showed that the deviation of means for gene expression between the remaining groups of samples were not statistically significant.

The t-test showed that the deviation of means for these data points were not statically significant.

Summarizing of the results of Example 1, the Prep-X treatment supplemented with a NASH-specific formulation included at the midway point of combination treatment had a significant effect on fibrosis and fibrogenesis in Mdr2 knockout mice. No such effect was noticed in the Prep-X treatment supplemented with an HCV-specific formulation included at the midway point of the combination treatment. An antifibrotic effect, i.e., a significant decrease of liver collagen and an improvement in liver architecture, was shown in male Mdr2 knockout mice; however, total collagen in female Mdr2 knockout mice was not shown to decrease significantly with the use of the Prep-X/NASH formulation.
The central profibrogenic transcript (procollagen I mRNA) was significantly downregulated both in male and in female Mdr2 knockout mice. Also, the finding that profibrogenic transcripts for integrin alpha v beta 6 and TIMP-1 were significantly downregulated in female Mdr2 knockout mice supports the conclusion of an antifibrotic effect in these mice, despite no significant change was shown in total liver collagen. These beneficial changes were also reflected by a decrease, though not shown to be of statistical significance, of the liver transaminases, especially in female Mdr2 knockout mice having higher serum levels than their male counterparts.
Example 2
The purpose of this experiment was to test for the potential of an antioxidant formulation, either alone or in combination with an HCV-specific or a NASH-specific supplemental formulation, to reverse an established fibrosis stimulated by an injection regiment of thioacetamide (TAA).
Sixty-eight six-week-old male C57BL/6J mice were used in this study. Eight of these mice were used, without intervention under healthy controls, as the control group. Sixty mice were injected intraperitoneally three times a weak with escalation doses—0.1, 0.2, 0.3, 0.4 g/kg—of TAA for six weeks to induce liver fibrosis. Six of treated animals died during TAA-injunction and were excluded from the study. Three days following the last injection, eleven mice were sacrificed as a control for fibrosis induction. The remaining forty-three mice received a daily application of an antioxidant cocktail comprising the formulation and dose identified in Table 1 (“Prep-X”) in a 10 μl vehicle per g body weight by intragastic gavage. Mice receiving only the vehicle were used as the control group. Fifteen mice continued the daily treatment for four weeks. Fourteen mice continued the treatment daily for two weeks. Beginning in the third week of the treatment regimen, these fourteen mice continued to receive Prep-X supplemented with an HCV-specific supplemental formulation whose constituents and dose are shown in Table 1. This treatment continued daily for two additional weeks. Fourteen other mice continued the daily treatment for three weeks. Beginning in the third week of the treatment regimen, these fourteen mice continued to receive Prep-X supplemented with a NASH-specific supplemental formulation whose constituents and dose are shown in Table 1. This treatment continued daily for two additional weeks. At 10 weeks, after undergoing four weeks of treatment, the mice were sacrificed by cardiac puncture and exsanguination under general anesthesia. The livers and spleens of the mice were excised, weighed, and snap-frozen in liquid nitrogen for further analysis. All the mice were housed with 12-hour light-dark cycles and fed with water and standard rat/mouse pellet chow ad libitum. Table 4 shows the relative and total hepatic collagen content of the livers and the weights of the liver and spleen for each of the groups of mice.

Relative hydroxyproline content and total hepatic collagen content was determined by the procedure earlier disclosed herein.

The differences between the means of the healthy control group without intervention and the control group for fibrosis induction had statistical significance with respect to the relative collagen content and the total collagen content but were not statistically significant for either liver weights or spleen weights using the t-test. The t-test showed that the deviation of means for the groups of mice undergoing different treatment methodologies was not statistically significant.

FIG. 3C is an image, with five times magnification, of a representative liver section of a mouse using connective tissue staining after TAA-induction for six weeks and then undergoing treatment receiving only the vehicle over a four week period. FIG. 3D is an image, with five times magnification, of a representative liver section of a mouse using connective tissue staining after TAA-induction for six weeks and then undergoing treatment receiving Prep-X over a four week period with the HCV-specific supplemental formulation included at the midway point of the combination treatment. FIG. 3E is an image, with five times magnification, of a representative liver section of a mouse using connective tissue staining after TAA-induction for six weeks and then undergoing treatment receiving Prep-X over a four week period with the NASH-specific supplemental formulation included at the midway point of the combination treatment.
FIGS. 4A-4C respectively represent profibrogenic gene expression of procollagen α1(1) encoding the major scar collagen; TIMP-1; and interstitial collagenase MMP-13. The quantitative real-time RT-PCR results, determined by the procedure as further defined herein, are expressed in arbitrary units relative to the internal standard β2-microglobulin mRNA. The data are expressed as x-fold increase (mean±standard error of mean) versus the livers from the control mice. The t-test showed that the differences between the means of the healthy control group without intervention and the control group for fibrosis induction had statistical significance for each of the three gene expressions. The t-test showed that the deviation of means for the groups of mice undergoing different treatment methodologies for each of three gene expressions was not statistically significant.
Neither the HCV-specific nor the NASH-specific supplemental formulations used in a treatment regiment with Prep-X had a statistically significant affect on fibrosis and fibrogenesis in the model of reversal of established fibrosis induced by TAA. A significant decrease of liver collagen and an improvement in liver architecture when compared to untreated fibrotic mice is not demonstrated by this experiment. This was also supported by a lack of alterations in the expression of profibrogenic or fibrolytic genes in the animals that received Prep-X treatment.
