     FIELD OF THE INVENTION 
     The present invention relates to unit dosage forms of 3β-arachidylamido-7α,12α-dihydroxy-5β-cholan-24-oic acid (Aramchol™) and use thereof in the treatment and/or inhibition of fibrosis. 
     BACKGROUND OF THE INVENTION 
     Aramchol™ is an amide conjugate of arachidic acid and 3-aminocholic acid, effective in reducing liver fat content as well as improving metabolic parameters associated with fatty liver disease. It is an oral, liver-targeted, fatty acid-bile acid conjugate that down-regulates stearoyl CoA type 1 desaturase. It belongs to a family of synthetic Fatty-Acid/Bile-Acid Conjugates (FABACs) and is being developed as a potentially disease modifying treatment for fatty liver disease and Non Alcoholic SteatoHepatitis (NASH). 
     Aramchol™ is chemically named 3β-arachidylamido-7α,12α-dihydroxy-5β-cholan-24-oic acid (or (4R)-4-((3S,5S,7R,10S,12S,13R,17R)-7,12-dihydroxy-3-icosanamido-10,13-dimethylhexadecahydro-1H-cyclopenta[a]phenanthren-17- yl)pentanoic acid, (IUPAC name)), and is represented by the following chemical structure: 
     
       
         
         
             
             
         
       
     
     Aramchol™, processes for its preparation, and use thereof are disclosed in U.S. Pat. No. 6,384,024; U.S. Pat. No. 6,395,722; U.S. Pat. No. 6,589,946; U.S. Pat. No. 7,501,403; U.S. Pat. No. 8,110,564; U.S. 2012/0214872; and WO 2009/060452. 
     Fibrosis 
     The formation of fibrous connective tissue is part of the normal healing process following tissue damage due to injury or inflammation. During this process, activated immune cells including macrophages stimulate the proliferation and activation of fibroblasts, which in turn deposit connective tissue. However, abnormal or excessive production of connective tissue may lead to accumulation of fibrous material such that it interferes with the normal function of the tissue. Fibrotic growth can proliferate and invade healthy surrounding tissue, even after the original injury heals. Such abnormal formation of excessive connective tissue, occurring in a reparative or reactive process, is referred to as fibrosis. 
     Physiologically, fibrosis acts to deposit connective tissue, which can obliterate the architecture and function of the underlying organ or tissue. Defined by the pathological accumulation of extracellular matrix (ECM) proteins, fibrosis results in scarring and thickening of the affected tissue, which interferes with normal organ function. In various conditions, the formation of fibrotic tissue is characterized by the deposition of abnormally large amounts of collagen. The synthesis of collagen is also involved in a number of other pathological conditions. For example, clinical conditions and disorders associated with primary or secondary fibrosis, such as systemic sclerosis, graft-versus host disease (GVHD), pulmonary fibrosis and autoimmune disorders, are distinguished by excessive production of connective tissue, which results in the destruction of normal tissue architecture and function. These diseases can best be interpreted in terms of perturbations in cellular functions, a major manifestation of which is excessive collagen synthesis and deposition. The role of collagen in fibrosis has prompted attempts to develop drugs that inhibit its accumulation. 
     Hepatic Fibrosis 
     Fibrosis of the liver, also referred to herein as hepatic fibrosis, may be caused by various types of chronic liver injury, especially if an inflammatory component is involved. Self-limited, acute liver injury (e.g., acute viral hepatitis A), even when fulminant, does not necessarily distort the scaffolding architecture and hence does not typically cause fibrosis, despite loss of hepatocytes. However, factors such as chronic alcoholism, malnutrition, hemochromatosis, and exposure to poisons, toxins or drugs, may lead to chronic liver injury and hepatic fibrosis due to exposure to hepatotoxic chemical substances. Hepatic scarring, caused by surgery or other forms of injury associated with mechanical biliary obstruction, may also result in liver fibrosis. 
     Fibrosis itself is not necessarily symptomatic, however it can lead to the development of portal hypertension, in which scarring distorts blood flow through the liver, or cirrhosis, in which scarring results in disruption of normal hepatic architecture and liver dysfunction. The extent of each of these pathologies determines the clinical manifestation of hepato-fibrotic disorders. For example, congenital hepatic fibrosis affects portal vein branches, largely sparing the parenchyma. The result is portal hypertension with sparing of hepatocellular function. 
     Treatment 
     Attempts to develop anti-fibrotic agents for the treatment of various disorders have been reported. However, treatment of established fibrosis, formed after months or years of chronic or repeated injury, remains a challenge. In its initial stages, hepatic fibrosis may regress if the cause is reversible (e.g. with viral clearance). Thus, the majority of available treatment options are designed to remove the basis of the liver injury, such as by eliminating hepatitis B virus or hepatitis C virus in chronic viral hepatitis, abstaining from alcohol in alcoholic liver disease, removing heavy metals such as iron in hemochromatosis or copper in Wilson disease, and decompressing bile ducts in biliary obstruction. 
     Treatments aimed at reversing the fibrosis are usually too toxic for long-term use (e.g. corticosteroids, penicillamine) or have no proven efficacy (e.g. colchicine). Silymarin, present in milk thistle, is a popular alternative medicine used to treat hepatic fibrosis, appears to be safe but to lack efficacy. 
     Potential Therapeutic Agents 
     Attempts to develop specific anti-fibrotic agents for the treatment of liver diseases have been reported. For example, U.S. Pat. No. 8,729,046 relates to methods for treating fibrosis of a tissue, including fibrosis of the liver, using combinations of nucleic acids or nucleic acid analogs. Specifically, the nucleic acids or analogs thereof are targeted to microRNAs of the miR23b cluster. U.S. Pat. No. 6,562,829 discloses compositions for treating hepatic fibrosis and methods of using and manufacturing the composition, the composition comprising a quinazolinone derivative, preferably Halofuginone. U.S. Pat. No. 8,858,954 is directed to pharmaceutical composition for preventing and treating liver fibrosis or nonalcoholic fatty liver disease, comprising 50 to 90% by weight of Cordyceps sinensis mycelium powder, and 10 to 50% by weight of condensed astragalus powder. 
     U.S. Pub. No. 2015/359805 relates to Farnesoid X receptor (FXR) modulators which can be used for the treatment of cholestatic disorders, in particular to bile acid derivatives wherein the C6 contains an ethyl and the C24 carboxy group is transformed into a sulphate group. Among the disorders suggested to be treated are alcoholic liver disease, living donor transplant liver regeneration, congenital hepatic fibrosis, choledocholithiasis, and granulomatous liver disease. U.S. 2014/187633 is directed to methods of treating and/or preventing non-alcoholic seatohepatitis (NASH) and/or primary biliary cirrhosis comprising administering to a subject in need thereof a pharmaceutical composition comprising eicosapentaenoic acid or a derivative thereof. The FXR agonist, obeticholic acid, which is a modified bile acid, is in phase III clinical trials for primary biliary cirrhosis. Use of this drug has been reported to be commonly associated with side effects such as pruritus. 
     Ursodeoxycholic acid (UDCA, Ursodiol) is the most frequently used treatment for primary biliary cirrhosis. It is one of the secondary bile acids, which are metabolic byproducts of intestinal bacteria. The drug is considered to assist in reducing the cholestasis and improves blood test results (liver function tests). However it has a minimal effect on symptoms and whether it improves prognosis is controversial. To relieve itching caused by bile acids in circulation, which would normally be removed by the liver, cholestyramine (a bile acid sequestrant) may be prescribed to primary biliary cirrhosis patients. The agent may assist in absorbing bile acids in the gut to be eliminated, rather than re-enter the blood stream. Alternative agents include stanozolol, naltrexone and rifampicin. 
     Obeticholic acid (OCA, Ocaliva) is a semi-synthetic bile acid analogue undergoing development in phase 2 and 3 studies for specific liver and gastrointestinal conditions. The FDA granted accelerated approval to Ocaliva on 27 May 2016 for the treatment of primary biliary cholangitis (PBC) in combination with ursodeoxycholic acid (UDCA) in adults with an inadequate response to UDCA, or as a single therapy in adults unable to tolerate UDCA. In addition, a phase 2 trial in NASH patients showed that administration of OCA reduced markers of liver inflammation and fibrosis and increased insulin sensitivity. 
     WO 2014/197738 and WO 2016/094570 relate to small molecule compounds, disclosed to be inhibitors of myofibroblast trans-differentiation and activation. Drugs and combinations suggested for the treatment of inter alia fatty liver were disclosed, for example, in WO 2016/112305 and EP2632925 (acetyl-CoA carboxylase inhibitors) as well as WO 2016/154258 (dual PPAR delta/gamma agonists). Some of the disclosed compounds were suggested to be used in combination with various other drugs. 
     Many patients do not respond to available treatments for fibrotic disorders, and long-term treatment is limited by toxicity and side effects. Therefore, a need remains for developing therapeutic modalities aimed at reducing fibrosis, especially hepatic fibrosis. The development of safe and effective treatments for established cirrhosis and portal hypertension and for attenuating fibrosis would be highly beneficial. 
     SUMMARY OF THE INVENTION 
     Fatty Acid Bile Acid Conjugates 
     Fatty acid bile salt conjugates, referred to also as Fatty Acid Bile Acid Conjugates (FABACs), are a family of synthetic molecules that may be used to improve conditions related to bile acids or cholesterol metabolism.

     Indications. 
     The invention is based, in part, on the surprising discovery that Aramchol™ exerts a potent anti-fibrotic effect, independent of its reported activities on fatty liver and steatosis, and reduces and inhibits the development of fibrosis in various experimental models. Specifically, treatment with Aramchol™ (5 mg/kg) significantly inhibited the development of toxin-induced cirrhosis, necrosis and liver fibrosis in an in vivo thioacetamide (TAA) model. Aramchol™ was also found to be unexpectedly superior to obaticholic acid (OCA), which did not induce statistically significant reduction in these parameters under the tested experimental conditions. In addition, Aramchol™ significantly reduced COL1A1 expression in LX-2 human hepatic stellate cells via PPARγ up-regulation. Aramchol™ was surprisingly found to be effective in reversing established fibrosis, and in reducing the production of collagen specifically in stellate cells. 
     Thus, independently from its reported activities on liver metabolism in subjects with NAFLD, Aramchol™ is surprisingly found herein to be effective in the treatment of new patient populations and patient subpopulations, such as in the treatment of patients with NAFLD or NASH who have not yet developed fibrosis. In addition, Aramchol™ was found to be effective in the treatment of non-hepatic fibrosis and various conditions characterized by fibrosis of environmental and/or immune etiology, hepatic fibrosis in patients with NAFLD or NASH, treatment of hepatic fibrosis in patients with NAFLD or NASH and advanced fibrosis (i.e. stage 2 or stage 3 fibrosis), treatment of hepatic fibrosis in patient with NAFLD or NASH who have cirrhosis (i.e. stage 4 fibrosis), treatment of hepatic fibrosis caused by contact with drugs, toxins or surgery, and specifically in alleviating hepatic cirrhosis, treatment of fibrosis without worsening of NAFLD or NASH, treatment of fibrosis without progression to Cirrhosis. The invention advantageously provides for the treatment of these new patient populations with enhanced efficacy and/or safety and minimized side effects. 
     In various embodiments, the fibrosis may be pulmonary fibrosis (e.g. idiopathic pulmonary fibrosis, diffuse interstitial pulmonary fibrosis, pleural fibrosis and fibrosis associated with asthma, fibrous dysplasia, cystic fibrosis), heart fibrosis (e.g. endomyocardial fibrosis and fibrosis associated with cardiovascular disease), kidney fibrosis (e.g. associated with renal failure), dermal fibrosis (e.g. keloid), ocular fibrosis, mucosal fibrosis, fibrosis of the central nervous system, fibrosis in bone or bone marrow, fibrosis in an endocrine organ (e.g. pancreas), fibrosis in the gastro-intestinal system, mediastinal fibrosis, postfibrinous fibrosis, proliferative fibrosis, retroperitoneal fibrosis, pancreatic fibrosis, fibrosis associated with an autoimmune disease (e.g. systemic lupus erythematosus (SLE), Sjogren syndrome, or diffuse systemic sclerosis with scleroderma). 
     For example, endomyocardial fibrosis an idiopathic type of myocardiopathy that is endemic in various parts of Africa and rarely in other areas, characterized by cardiomegaly, marked thickening of the endocardium with dense white fibrous tissue that may extend to involve the inner myocardium, and by congestive heart failure. 
     Idiopathic pulmonary fibrosis (e.g. diffuse idiopathic interstitial fibrosis, diffuse interstitial pulmonary fibrosis) is achronic inflammatory progressive fibrosis of the pulmonary alveolar walls, with steadily progressive dyspnea, resulting in death from oxygen lack or right heart failure. Most cases are of unknown origin, although some are thought to result from pneumoconiosis, hypersensitivity pneumonitis, scleroderma, and other diseases. 
     Mediastinal fibrosis is characterized by development of hard white fibrous tissue in the upper portion of the mediastinum, sometimes obstructing the air passages and large blood vessels; called also fibrosing or fibrous mediastinitis. 
     Pleural fibrosis is characterized by fibrosis of the visceral pleura so that part or all of a lung becomes covered with a plaque or a thick layer of nonexpansible fibrous tissue. The more extensive form is called fibrothorax. 
     Postfibrinous fibrosis occurs in tissues in which fibrin has been deposited. 
     Proliferative fibrosis refers to a condition in which the fibrous elements continue to proliferate after the original causative factor has ceased to operate. 
     Retroperitoneal fibrosis (Ormond disease, periureteral fibrosis) is characterized by deposition of fibrous tissue in the retroperitoneal space, producing vague abdominal discomfort, and often causing blockage of the ureters, with resultant hydronephrosis and impaired renal function, which may result in renal failure.

     Combination Therapy 
     The C-C motif chemokine receptor CCR5 is involved in the process by which HIV, the virus that causes AIDS, enters cells. CCR5 receptor antagonists are a class of small molecules that antagonize the CCR5 receptor. Hence, antagonists of this receptor are entry inhibitors and have potential therapeutic applications in the treatment of HIV infections. The C-C chemokine receptor type 2 (CCR2) is a protein that in humans is encoded by the CCR2 gene. This gene encodes two isoforms of a receptor for monocyte chemoattractant protein-1 (CCL2), a chemokine which specifically mediates chemotaxis of cells such as monocytes and macrophages. Cenicriviroc ((S,E)-8-(4-(2-Butoxyethoxy)phenyl)-1-isobutyl-N-(4-(((1-propyl-1H-imidazol-5-yl)methyl)sulfinyl)phenyl)-1,2,3,4-tetrahydrobenzo[b]azocine-5-carboxamide, CAS No. 497223-25-3) is an inhibitor of both CCR2 and CCR5 receptors.

     The administration of two drugs to treat a given condition, such as non-alcoholic fatty liver disease (NAFLD), raises a number of potential problems. In vivo interactions between two drugs are complex. The effects of any single drug are related to its absorption, distribution, and elimination. When two drugs are introduced into the body, each drug can affect the absorption, distribution, and elimination of the other and hence, alter the effects of the other. For instance, one drug may inhibit, activate or induce the production of enzymes involved in a metabolic route of elimination of the other drug. (Guidance for Industry, 1999) Thus, when two drugs are administered to treat the same condition, it is unpredictable whether each will complement, have no effect on, or interfere with the therapeutic activity of the other in a human subject. 
     Not only may the interaction between two drugs affect the intended therapeutic activity of each drug, but the interaction may increase the levels of toxic metabolites (Guidance for Industry, 1999). The interaction may also heighten or lessen the side effects of each drug. Hence, upon administration of two drugs to treat a disease, it is unpredictable what change will occur in the negative side effect profile of each drug. 
     Additionally, it is difficult to accurately predict when the effects of the interaction between the two drugs will become manifest. For example, metabolic interactions between drugs may become apparent upon the initial administration of the second drug, after the two have reached a steady-state concentration or upon discontinuation of one of the drugs. (Guidance for Industry, 1999) 
     It is understood that where a parameter range is provided, all integers within that range, and tenths thereof, are also provided by the invention. For example, “0.2-5 mg/kg/day” is a disclosure of 0.2 mg/kg/day, 0.3 mg/kg/day, 0.4 mg/kg/day, 0.5 mg/kg/day, 0.6 mg/kg/day etc. up to 5.0 mg/kg/day. 
     Each embodiment disclosed herein is contemplated as being applicable to each of the other disclosed embodiments. Thus, all combinations of the various elements described herein are within the scope of the invention. 
     The following examples are presented in order to more fully illustrate some embodiments of the invention. They should, in no way be construed, however, as limiting the broad scope of the invention. 
     EXAMPLES 
     Examples are provided below to facilitate a more complete understanding of the invention. The following examples illustrate the exemplary modes of making and practicing the invention. However, the scope of the invention is not limited to specific embodiments disclosed in these Examples, which are for purposes of illustration only. 
     Example 1 
     Thioacetamide (TAA)—Induced Fibrosis—Model for Hepatic Cirrhosis 
     Liver fibrosis was induced in Wistar rats by intraperitoneal injections of TAA (20 mg/100 gr body weight) twice per week during 10 weeks. I.p. application of TAA results in hepatic centrolobular necrosis, elevated transaminase activity and robust liver fibrosis. Treatment groups further included co-administration of Aramchol™ (1 or 5 mg/kg orally) or obaticholic acid (OCA, 5 mg/kg). A control group of saline-treated rats (in the absence of TAA administration) was further included. Rats were then sacrificed, and livers were observed macroscopically for signs of cirrhosis and necrotic lesions, and microscopically, following Masson Goldner staining. The fibrosis score, calculated at a scale of 0-4, was determined for each sample, wherein 0 indicates no fibrosis and 4 indicates advanced fibrosis and cirrhosis. 
     As can be seen in  FIGS. 1A-1D and 2A-2B , treatment with Aramchol™ (5 mg/kg) significantly prevented TAA induced fibrosis. The treatment reduced significantly the development of necrosis and cirrhosis ( FIGS. 1A-1D ), as well as the fibrotic score and collagen distribution in the tissue ( FIGS. 2A-2B ), in a dose-dependent manner. In contradistinction, OCA did not induce statistically significant reduction in these parameters. 
     Thus, Aramchol™ was surprisingly found to be a potent anti-fibrotic and anti-cirrhotic agent. Aramchol™ was also found to be unexpectedly superior to OCA and provide for improved, effective treatment for liver fibrosis. 
     Cirrhosis and portal hypertension from TAA intoxication may eventually lead to the development of acute liver failure and associated conditions such as hepatic encephalopathy, and the TAA model is also used in evaluating these phenomena. Accordingly, as disclosed herein, Aramchol™ may also be used in some embodiments for preventing acute or fatal liver failure and/or hepatic or portosystemic encephalopathy, for example toxin-induced liver failure and/or hepatic encephalopathy. 
     Example 2 
     Inhibition of Collagen Synthesis in Stellate Cells 
     LX2 cells (150.000 cells per well) were plated in DMEM media containing antibiotics, glutamine and bovine fetal serum. After 24 hours incubation, media was changed to 0% serum and incubated for an additional period of 16 hours. Then, Aramchol™ (10 mM) was added and 24 hours later RNA was extracted with Trizol. 
     Surprisingly, as can be seen in  FIGS. 3 and 4 , COL1A1 expression in LX-2 human hepatic stellate cells was reduced by Aramchol™ via PPARγ up-regulation. 
     Consistently, Aramchol™ significantly down regulates collagen production in LX-2 human hepatic stellate cells relative to a DMSO control ( FIG. 5 ). Again, Aramchol™ was surprisingly found to be effective in reducing the production of collagen specifically in stellate cells. 
     Example 3 
     Aramchol™ Reduces Established Fibrosis in a MCD Diet Animal Model 
     The study described below investigates the mechanism of action of Aramchol™ and its potential effect on fibrosis using the 0.1% methionine- and choline-deficient (0.1 MCD) diet mouse model of NASH. 
     C57B1/6 were fed the Methionine and Choline Deficient (MCD) and control diet and were sacrificed after 4 weeks. The MCD diet induces aminotransferase elevation and changes in hepatic histological features, characterized by steatosis, local inflammation, hepatocyte necrosis and fibrosis. These changes occur rapidly and are morphologically similar to those observed in human NASH. In this study the MCD diet contained 0.1% methionine to minimize and stabilize weight loss. At the end of the second week, after verification of established NASH, 0.1MCD-fed mice were treated orally by gavage with Aramchol™ (5 mg/Kg/day) or vehicle (n=10, each condition). Control diet-fed mice were also treated with vehicle for same duration (n=10). At the end of the experiment, blood and liver samples were obtained. A diagram of the experimental design is shown below: 

 
     Results from the study showed: 1) treatment with Aramchol™ significantly down regulates steatosis in the liver ( FIGS. 6A-6B ); 2) treatment with Aramchol™ significantly down regulates/normalizes infiltration and activation status of macrophages in the liver ( FIG. 7A-7C ); 3) treatment with Aramchol™ significantly down regulates/normalizes fibrosis in the liver ( FIGS. 8A-8B ); 4) Aramchol™ significantly down regulates collagen in the liver ( FIGS. 9 ); and 5) Aramchol™ significantly up regulates glutathione and elevates GSH/GSSG ratio in 0.1% MCD mice ( FIGS. 10A-10B ). 
     Additionally, Aramchol™ treatment further reduced SCD1 activity, which was evidenced by a marked decrease in SCD1 expression, in the FA(16:1)/FA(16:0) ratio and in the total content of monounsaturated FA (MUFA), which led to a reduction in the hepatic content of diglycerides (DG) and TG. Aramchol™ treatment improved oxidative stress, as shown by the normalization of the GSH/GSSG ratio, a biomarker of the cellular redox potential, and a marked reduction in the content of total oxFA including oxLA, which has been associated with liver injury in human NASH.

     This is a multicenter, Phase IIb, randomized, double blind, placebo-controlled study designed to evaluate the efficacy and safety of two Aramchol™ doses in subjects that are 18 to 75 years of age, with Non-Alcoholic Steatohepatitis (NASH) confirmed by liver biopsy performed in a period of 6 months before entering the study, with overweight or obesity and who are pre diabetic or type II diabetic. 
     Eligible subjects will be enrolled into three treatments arms: Aramchol™ 400 and 600 mg tablets and placebo tablets in ratio 2:2:1. 
     The subjects will be evaluated at study sites for 11 scheduled visits: at screening (visit 1(weeks-4-0)), baseline (visit 2 (day 0)), visit 3 (week 2), visit 4 week 4), visit 5 (week 8), visit 6 (week 12), visit 7 (week 24), visit 8 (week 32), visit 9 (week 40) and visit 10 (week 52 - (End of Treatment/early termination visit)). After completion of the study treatment period, the subjects will be followed for an additional period of 13 weeks without study medication (until visit 11 (week 65)). 
     During the screening period, the severity of the disease will be evaluated with blood tests, liver biopsy and NMRS. 
     During the study the following assessments will be performed:
         a. Vital signs will be measured at each study visit.   b. A physical examination will be performed at the screening visit, 24 weeks, End of       

     Treatment/early termination and week 65 visit. 
     The following blood tests will be performed: complete blood count (CBC), serum chemistry (including electrolytes, liver enzymes, direct and total bilirubin, glucose, lipid profile which include triglyceride, cholesterol, HDL, LDL and VLDL, CPK, creatinine, urea, albumin, alkaline phosphatase), ESR and urinalysis during the screening visit, baseline, week 2, 4, 8, 24, 40, 52 and 65 (end of follow up) visits. Serology (HBV, HCV and HIV) will be performed during the screening visit. Coagulation (fibrinogen, PT/INR, aPTT) will be measured in screening and baseline, week 24, End of Treatment/early termination and week 65 visits. Insulin (HOMA) will be measured in the screening, week 24 and End of Treatment/early termination visits. HbA1C will be measured in the screening, week 8, 24, 40 and End of Treatment/early termination visits. C reactive protein, Leptin, Adiponectin, CK-18 (M30 and M65), Ferritin, PAI-1, IL-6, TNF-alpha, FGF-19, C4 (7-alpha-hydroxy-4-cholesten-3-one), pool serum Bile Acids, B-hydroxybutyrate and Free Fatty Acids will be measured in baseline visit and end of treatment period. The blood samples taken at these visits, will be tested for possible biomarkers, including, but not limited to, Fetuine A and GDF15. TSH, T3 and T4 will be measured during the screening visit. beta-hCG in women of childbearing potential will be performed during the screening visit. A serum sample will be collected and kept frozen until study end in case special investigation needs to be performed. This sample will be collected during the screening and visit 10/Early Termination. 
     Body weight and waist circumference will be measured in screening, baseline, week 24, end of treatment and week 65 visits. Height will be measured during the screening visit. 
     ECG will be performed during the screening visit, visit 7 (week 24) and end of treatment visits. 
     All subjects will undergo two NMRS scans, at screening and end of treatment visits. 
     FibroMax test will be performed only if the investigator thinks it is necessary 
     Liver biopsy will be conducted during the screening and end of treatment visit. The biopsy in the screening visit will be performed only if it was not done within the 6 months prior to this visit. 
     Metabolomics blood test will be performed at the screening, visit 7 and the End-of-Treatment/Early Termination visits. From some consenting patients (about 15) a sample from the liver biopsy will be taken for analysis. 
     Endothelial Function will be conducted in selected sites. The test will be conducted during the baseline visit before the study treatment will be given and End of Treatment/early termination visit. 
     Blood sample for Aramchol™ trough level will be collected (pre-dose) from patients in Israel at baseline (visit 2) week 4 (visit 4), week 12 (visit 6), week 24 (visit 7), week 40 (visit 9), end of treatment (visit 10) and follow up (visit 11). At selected sites in Mexico, USA and Hong Kong one blood sample will be collected (pre-dose) on visit 4 (up to 10 subjects per country) to test for trough Aramchol™ blood level differences between populations (e.g., African American, Asian, Hispanic). 
     Blood sample for gene analysis will be taken from all consenting patients during the baseline visit, will be kept frozen and analyzed only at the study end. 
     Life style questionnaire will be completed in all visits. 
     Adverse events will be monitored throughout the study. 
     Concomitant Medications will be monitored throughout the study. 
     Telephone contacts will be performed on week 16, 20, 28, 36, 44 and 48. An interim safety analysis will be conducted as soon as 120 subjects will completed the follow up period of 24 weeks under study treatment. An independent DSMB will analyze the safety data and recommend a continued course of action. All patients will continue to be treated under the study protocol until conclusion of the analysis will be known. 
     Safety assessment will include frequency and severity of treatment-emergent AEs, clinically significant laboratory abnormalities, ECG changes and physical examination findings.

     Discussion 
     Based on studies described herein, Aramchol™ is surprisingly found to be a potent anti-fibrotic and anti-cirrhotic agent. Aramchol™ is also found to be unexpectedly superior to OCA and provides improved, effective treatment for liver fibrosis. Accordingly, Aramchol™ may be used to prevent acute or fatal liver failure and/or hepatic or portosystemic encephalopathy, for example toxin-induced liver failure and/or hepatic encephalopathy. 
     Furthermore, Aramchol™ is also surprisingly found to be effective in reversing established fibrosis. Aramchol™ treatment improves liver histology as determined by a reduction of lipid accumulation (Sudan red staining), fibrosis (Sirius red and SMA staining) and inflammation (F4/80 and CD64 staining). Indeed, Aramchol™ has an effect on fibrosis in addition to main pathologies of NASH, namely steatosis and inflammation. 
     Results presented herein show that Aramchol™ down-regulates collagen production from human stellate cells, the effects of Aramchol™ are mediated through down regulation of SCD 1 and up regulation of glutathione production, and the effect of Aramchol™ on fibrosis is mediated via down regulation of steatosis and inflammation as well as directly via down regulation of collagen production from stellate cells. Taken together, information herein supports the effects of Aramchol™ in human patients as set forth in the claims. 
     Results analogous to those of Example 4 for 400 mg or 600 mg doses are expected for higher doses of Aramchol™ that are recited herein. 
     Example 5 
     In vivo Studies with Aramchol™, a Stearoyl CoA Desaturase Inhibitor, in Human Subjects with NASH. One-Year Results of the Global Phase 2b Randomized Placebo-Controlled ARREST Trial. 
     In a 3-month, phase 2a human NAFLD study, Aramchol™ reduced hepatic fat. It also had antifibrotic effects in preclinical models. 
     The final results from the global phase 2b ARREST study evaluating a 1-year treatment with Aramchol™ in patients (pts) with NASH are reported herein. 
     Methods 
     Overweight/obese pts with pre-diabetes or diabetes and biopsy-proven NASH (with NAS≥4; F&lt;4) were included. Liver biopsy and liver fat measurement by MR spectroscopy (LF-MRS) were performed at baseline and week 52. Both read centrally. The primary endpoint was the absolute change from baseline in LF-MRS (600mg vs. placebo, PLB; mixed model repeated measures). Key secondary endpoints included: NASH resolution without fibrosis worsening, ≥1 stage fibrosis reduction without NASH worsening and ALT reduction. 
     Results 
     247 pts from 11 countries (US, Europe, Latin America) were randomized 2:2:1 to Aramchol™ 400 mg QD (N=101), 600 mg QD (N=98) or PLB (N=48). At baseline: 65% females, mean age 54.4 yrs, BMI 32.7 kg/m2, HbA1c 6.6%±1.0% (mean±SD), LF-MRS 28.5%±11.7% (mean±SD); 60% fibrosis stage 2-3 and NAS 5.12±1.00 (mean±SD). 89% of pts completed the study. The results of the study are summarized in  FIGS. 16A-16B  to FIGS.- 20 A- 20 B. 
     LF-MRS was significantly reduced vs PLB by 400 mg (p=0.045) and 600 mg (p&lt;0.066). A statistically significant ≥5% absolute reduction in liver fat was seen in 47% of pts on 600 mg vs 24% on PLB (p&lt;0.028) and 37% on 400 mg suggesting a dose response ( FIG. 16B ). Pts in the 600 mg arm had NASH resolution without fibrosis worsening more often than PLB: 16.7% vs. 5.0% respectively, (OR=4.74, 95% CI: 0.99-22.66, p=0.051)( FIG. 18A ). A ≥1 stage fibrosis reduction without NASH worsening occurred in 29.5% of the 600 mg arm vs 17.5% of the PLB arm (p=0.21)( FIG. 19A ). One (1.3%) pt progressed to cirrhosis in the 600 mg arm vs 6 (7.5%) in the 400 mg arm and 3 (7.5%) in the PLB arm ( FIG. 19B ). Both doses significantly reduced ALT (p&lt;0.001)( FIG. 20A ), AST (p=0.002)( FIG. 20B ) and HbA1c (p&lt;0.007) vs PLB in a dose response manner. Serum lipid parameters and body weight did not change. Discontinuation due to adverse events (AE) was &lt;5% and serious AE occurred in 10% of pts without a difference between arms. 
     Conclusion 
     In a one year, PLB-controlled, phase 2b trial in pts with NASH, Aramchol™ significantly reduced liver fat, improved histology, hepatic biochemistry and glycemic control with excellent safety and tolerability. The therapeutic potency of Aramchol™ for NASH should be tested in a larger, phase 3 trial. 
     Example 6 
     In vivo Studies with Aramchol™, in Human Subjects with NASH. Modelling and Simulation of 300 mg BID and 600 mg OD doses of ARAMCHOL™ in patients. 
     Table 1 summarizes the reported plasma exposure from three studies—single dose Phase I in healthy volunteers (30-900 mg, AUC=AUC inf ); Phase II ARAMCHOL™ 003 repeat dose study (AUC on D84 from 100 &amp; 300 mg QD), Phase IIb Cmin on D84 (400 and 600 mg QD). 

 
     Exposure in healthy volunteers is sub-proportional with an approximate four-fold decrease in AUC/Dose across the dose range 30-900 mg (397-97 ng/mL.h/(mg/kg)). Biovailability relative to 30 mg/kg has been calculated as (AUC/Dose)/(AUC/30 mg) and is plotted for this group in  FIG. 11 . 
     Exposure in patients is also sub-proportional from 100 to 300 mg. It is noted that the average steady-state AUC in this study at 300 mg (32992 ng/mL.h) is approximately 2-fold lower than the AUC inf  from a single dose in healthy volunteers (64285 ng/mL.h). This may be due to the use of a tablet formulation in the patient study versus the powder/suspension in healthy volunteers or may simply reflect a high degree of inter-subject variability (typically exposure CV is &gt;50% within a study group). 
     The steady state (day 84) C min  in patients at 400 mg and 600 mg has been measured. While the AUC in this study was not calculated, as the half-life is relatively long (&gt;24 h), C min , C max  &amp; C avg  is expected to be similar and so AUC can be approximated by C min *24 to allow comparison with other studies (the true value is expected to be slightly higher). This indicates that exposure at 400 mg (68616 ng/mL.h) is super-proportional relative to 300 mg in patients (32992 ng/mL.h) which is contrary to the general trend that AUC/Dose decreases with dose. Again, this may reflect inter-subject variability or a difference in the excipients used in the tablets. 
     Plots of AUC v Dose and AUC/Dose v Dose are shown in  FIGS. 12A and 12B . 
     Modelling and Simulation 
     Given the sub-proportional exposure generally seen, splitting the same total daily dose into two BID doses is likely to increase plasma AUC. The aim of this analysis was to model this behavior. 
     The 300 mg data on day 1 and day 84 in patients (Phase 2 ARAMCHOL™ 003) has been modelled in Phoenix 64® assuming single compartment pharmacokinetics (parameterized by Cl and V) and first order absorption at a rate Ka with a delay, Tlag. The fitted model parameters all have a CV&lt;25% and the predicted concentration data reasonably capture the observed data as shown in  FIGS. 13A-13C . 
     These model parameters were used to simulate exposure at 300 mg BID as shown in 
       FIGS. 14A-14B . The predicted steady state Cmin using this model is 2630 ng/mL with an AUC of 65500 ng/mL.h. 
     To predict exposure at 600 mg, a correction for sub-proportional PK (lower bioavailability at higher dose) has been made assuming the same non-linearity at observed in healthy volunteers. Based on,  FIGS. 13A-13C , relative bioavailability will be approximately 0.75 fold lower at 600 mg (ca. 0.4) compared to 300 mg (0.53) and the model parameters V/F and Cl/F from the 300mg data have been adjusted accordingly. 
     The simulated exposure from a 600 mg QD dose is shown in  FIGS. 15A-15B  with a predicted C min  of 1820 ng/mL and an AUC of 49100 ng/mL.h. 
     Given the variability in exposure between subjects and between studies, the absolute values of AUC and C min  are likely to differ from those predicted but a 300 mg BID dose is predicted, on average, to give a C min  approximately 1.4-fold higher than 600 mg QD and a 1.3-fold higher AUC. 
     In Summary: 
     Exposure of drug is expressed by area under the curve (AUC, the integrated concentration-time profile) and is often linear with dose. Under these circumstances, one dose of 900 mg Aramchol™ is expected to give three times the exposure (AUC) of 300 mg dose. However, it was found that higher doses result in a lower than linear increase in exposure. Accordingly, a single 900 mg dose gave only 1.35 fold higher exposure (AUC=86943 ng/mL.h) than a single 300 mg dose (AUC=64285ng/mL.h) in healthy volunteers, despite the 3 fold higher dose. This is likely due to incomplete absorption of Armachol at the higher dose level. Based on this relationship, two 300 mg doses, for example, with a 12 h dose interval are expected to give higher exposure than a single daily 600 mg dose by a factor of approximately 1.4.

     Mechanistic Studies with Aramchol™: Aramchol™ Downregulates SCD1 and Induces PPARγ in Hepatic Stellate Cells to Attenuate Cellular Activation and Fibrogenesis. 
     Background: 
     Activation of hepatic stellate cells (HSCs) drives hepatic fibrosis through a process that is inhibited by PPARy signaling. Aramchol™ (arachidyl amido cholanoic acid) is a fatty acid-bile acid conjugate that reduces liver fat content in nonalcoholic fatty liver disease (NAFLD) and improved nonalcoholic steatohepatitis (NASH) without worsening fibrosis in a Phase 2b study. Aramchol™ attenuates fibrosis in two distinct models (MCD diet and thioacetamide). In mice, Aramchol™ reduces liver fat by downregulating the fatty acid synthetic enzyme stearoyl Co-A desaturase 1 (SCD-1) in hepatocytes. The mechanism for Aramchol™&#39;s antifibrotic effect is not known; moreover, although HSCs also store lipids as retinyl esters. The role of SCD-1 in HSCs and the impact of Aramchol™ on SCD-1 activity are unknown. 
     Aim: 
     To investigate the direct anti-fibrotic effect of Aramchol™ on HSCs using LX-2, a human hepatic stellate cell line, and to define the mechanism of Aramchol™&#39;s effects on HSCs. 
     Methods: 
     Serum-starved LX2 cells were treated with Aramchol™ (10 μM) for 24 or 48 hours. Fibrogenic gene expression and SCD-1 protein expression were measured by qPCR and Western, respectively. RNAseq was performed at 24 and 48 h in duplicate. Differential gene expression was assessed with DSeq2, while gene set enrichment analysis (GSEA) and gene ontology (GO) analyses assessed functionality of gene expression changes. Primary hepatocytes from C57BL/6 mice were harvested by perfusion and treated with Aramchol™ (10 μM) for 48 hours in culture. PPAR γ mRNA expression was measured by qPCR. 
     Results: 
     Results are shown in  FIGS. 21A-21B  to  FIGS. 25A-25B . 
       FIGS. 21A-21B  depict how Aramchol™ downregulates SCD-1 mRNA and fibrogenic genes and upregulates PPARγ mRNA in HSCs. Based on RT-PCR (N=3) *p&lt;0.05, **p&lt;0.01, ***p&lt;0.001.

     Conclusions: 
     Aramchol™ elevates PPARγ mRNA and down regulates SCD-1 mRNA and protein and in hepatic stellate cells. By RNAseq and pathway analysis, Aramchol™ downregulates fibrogenic genes that are part of a clinically validated HSC activation signature, including COL1A1 and αSMA, as well as pathways involved in cholesterol biosynthesis &amp; homeostasis, and collagen formation. Aramchol™ upregulates PPARγ mRNA selectively in HSCs and not in hepatocytes.
