DefinitionsAs used in the present specification, the following words and phrases are generally intended to have the meanings as set forth below, except to the extent that the context in which they are used indicates otherwise.
As used herein, the term “about” used in the context of quantitative measurements means the indicated amount ±10%, or alternatively the indicated amount ±5% or ±1%.
The term “complex” refers to a formation resulting from the interaction between Compound I and another molecule.
The term “solvate” refers to a complex formed by combining Compound I and a solvent. As used herein, the term “solvate” includes a hydrate (i.e., a solvate when the solvent is water).
The term “co-crystal” refers to a molecular complex of an ionized or non-ionized Compound I (or any other compound disclosed herein) and one or more non-ionized co-crystal formers (such as a pharmaceutically acceptable salt) connected through non-covalent interactions. In certain embodiments, the co-crystal can have an improved property as compared to the free form (i.e., the free molecule, zwitter ion, hydrate, solvate, etc.) or a salt (which includes salt hydrates and solvates). In further embodiments, the improved property is selected from the group consisting of: increased solubility, increased dissolution, increased bioavailability, increased dose response, decreased hygroscopicity, a crystalline form of a normally amorphous compound, a crystalline form of a difficult to salt or unsaltable compound, decreased form diversity, more desired morphology, and the like.
The term “co-crystal former” or “co-former” refers to one or more pharmaceutically acceptable bases and/or pharmaceutically acceptable acids disclosed herein in association with Compound I, or any other compound disclosed herein.
Any formula or structure given herein, including Compound I, is also intended to represent unlabeled forms as well as isotopically labeled forms of the compounds. Isotopically labeled compounds have structures depicted by the formulae given herein except that one or more atoms are replaced by an atom having a selected atomic mass or mass number. Examples of isotopes that can be incorporated into compounds of the disclosure include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine and chlorine, such as, but not limited to 2H (deuterium, D), 3H (tritium), 11C, 13C, 14C, 15N, 18F, 31P, 32P, 35S, 36Cl and 125I. Various isotopically labeled compounds of the present disclosure, for example those into which isotopes such as 3H, 13C and 14C are incorporated, may be prepared. Such isotopically labeled compounds may be useful in metabolic studies, reaction kinetic studies, detection or imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT) including drug or substrate tissue distribution assays or in radioactive treatment of patients.
The disclosure also includes Compound I in which from 1 to “n” hydrogens attached to a carbon atom is/are replaced by deuterium, in which n is the number of hydrogens in the molecule. Such compounds exhibit increased resistance to metabolism and may be thus useful for increasing the halflife of any Compound I when administered to a mammal. See, for example, Foster, “Deuterium Isotope Effects in Studies of Drug Metabolism”, Trends Pharmacol. Sci. 5(12):524-527 (1984). Such compounds are synthesized by means well known in the art, for example by employing starting materials in which one or more hydrogen atoms have been replaced by deuterium.
Deuterium labeled or substituted compounds of the disclosure may have improved DMPK (drug metabolism and pharmacokinetics) properties, relating to distribution, metabolism and excretion (ADME). Substitution with heavier isotopes such as deuterium may afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements. An 18F labeled compound may be useful for PET or SPECT studies. Isotopically labeled compounds of this disclosure and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations described below by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent. Further, substitution with heavier isotopes, particularly deuterium (i.e., 2H or D) may afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements or an improvement in therapeutic index. It is understood that deuterium in this context is regarded as a substituent in Compound I.
The concentration of such a heavier isotope, specifically deuterium, may be defined by an isotopic enrichment factor. In the compounds of this disclosure any atom not specifically designated as a particular isotope is meant to represent any stable isotope of that atom. Unless otherwise stated, when a position is designated specifically as “H” or “hydrogen”, the position is understood to have hydrogen at its natural abundance isotopic composition. Accordingly, in the compounds of this disclosure any atom specifically designated as a deuterium (D) is meant to represent deuterium.

Pharmaceutical Compositions and Modes of AdministrationThe forms of Compound I as described herein may be administered in the form of a pharmaceutical composition. Thus, provided herein are also pharmaceutical compositions that contain one or more of the forms of Compound I described herein and one or more pharmaceutically acceptable vehicles selected from carriers, adjuvants and excipients. Suitable pharmaceutically acceptable vehicles may include, for example, inert solid diluents and fillers, diluents, including sterile aqueous solution and various organic solvents, permeation enhancers, solubilizers and adjuvants. Such compositions are prepared in a manner well known in the pharmaceutical art. See, e.g., Remington's Pharmaceutical Sciences, Mace Publishing Co., Philadelphia, Pa. 17th Ed. (1985); and Modern Pharmaceutics, Marcel Dekker, Inc. 3rd Ed. (G. S. Banker & C. T. Rhodes, Eds.). The pharmaceutical compositions may be administered alone or in combination with other therapeutic agents.
The pharmaceutical compositions may be administered in either single or multiple doses. The pharmaceutical composition may be administered by various methods including, for example, rectal, buccal, intranasal and transdermal routes. In certain embodiments, the pharmaceutical composition may be administered by intra-arterial injection, intravenously, intraperitoneally, parenterally, intramuscularly, subcutaneously, orally, topically, or as an inhalant.
One mode for administration is parenteral, for example, by injection. The forms in which the pharmaceutical compositions described herein may be incorporated for administration by injection include, for example, aqueous or oil suspensions, or emulsions, with sesame oil, corn oil, cottonseed oil, or peanut oil, as well as elixirs, mannitol, dextrose, or a sterile aqueous solution, and similar pharmaceutical vehicles.
Oral administration may be another route for administration of one or more of the forms of Compound I described herein. Administration may be via, for example, capsule or enteric coated tablets. In making the pharmaceutical compositions that include one or more of the forms of Compound I described herein, the active ingredient is usually diluted by an excipient and/or enclosed within such a carrier that can be in the form of a capsule, sachet, paper or other container. When the excipient serves as a diluent, it can be in the form of a solid, semi-solid, or liquid material, which acts as a vehicle, carrier or medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active ingredient, soft and hard gelatin capsules, sterile injectable solutions, and sterile packaged powders.
Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, sterile water, syrup, and methyl cellulose. The formulations can additionally include lubricating agents such as talc, magnesium stearate, and mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl and propylhydroxy-benzoates; sweetening agents; and flavoring agents.
The compositions that include one or more of the forms of Compound I described herein can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the subject by employing procedures known in the art. Controlled release drug delivery systems for oral administration include osmotic pump systems and dissolutional systems containing polymer-coated reservoirs or drug-polymer matrix formulations. Examples of controlled release systems are given in U.S. Pat. Nos. 3,845,770; 4,326,525; 4,902,514; and 5,616,345. Another formulation for use in the methods disclosed herein employ transdermal delivery devices (“patches”). Such transdermal patches may be used to provide continuous or discontinuous infusion of the forms of Compound I described herein in controlled amounts. The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art. See, e.g., U.S. Pat. Nos. 5,023,252, 4,992,445 and 5,001,139. Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents.
For preparing solid compositions such as tablets, the principal active ingredient may be mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of the forms of Compound I described herein. When referring to these preformulation compositions as homogeneous, the active ingredient may be dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules.
The tablets or pills of the forms of Compound I described herein may be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action, or to protect from the acid conditions of the stomach. For example, the tablet or pill can include an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer that serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate.
Compositions for inhalation or insufflation may include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described herein. In some embodiments, the compositions are administered by the oral or nasal respiratory route for local or systemic effect. In other embodiments, compositions in pharmaceutically acceptable solvents may be nebulized by use of inert gases. Nebulized solutions may be inhaled directly from the nebulizing device or the nebulizing device may be attached to a facemask tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions may be administered, preferably orally or nasally, from devices that deliver the formulation in an appropriate manner.
The forms of Compound I as described herein may be administered in a pharmaceutically effective amount. For oral administration, each dosage unit can contain from 1 mg to 2 gram, 1 mg to 1 gram, or 1 mg to 500 mg of Compound I. In some embodiments, the dose is from 1 mg to 250 mg of Compound I. In some embodiments, a dose of Compound I ranges from about 20 mg twice a day to about 50 mg twice a day. In some embodiments, the dose is 2 mg, 4 mg, 6 mg, 8 mg, 10 mg, 12 mg, 14 mg, 16 mg, 18 mg, 20 mg, 25 mg, 25 mg, 30 mg, 35 mg, 40 mg, 45 mg, 50 mg, 75 mg, 100 mg, 200 mg, or 500 mg of Compound I. It will be understood, however, that the amount of the compound actually administered usually will be determined by a physician in light of the relevant circumstances including the condition to be treated, the chosen route of administration, and co-administration compound and if applicable, the age, weight, response of the individual patient, the severity of the patient's symptoms, and the like.
The forms of Compound I of the present application or the compositions thereof may be administered once, twice, three, or four times daily, using any suitable mode described above. Also, the forms of Compound I of the present application or the compositions thereof may be administered once or twice a week, once every two weeks, once every three weeks, once every four weeks, once every five weeks, or once every six weeks.

For example, the forms of Compound I of the present application or the compositions thereof may be administered to the subject (e.g., a human) within minutes or hours of consuming calories (e.g., a meal). In some embodiments, the forms of Compound I of the present application or the compositions thereof may be administered to the subject (e.g., a human) within 5-10 minutes, about 30 minutes, or about 60 minutes of consuming calories.
ASK 1 and Methods of UseApoptosis signal-regulating kinase 1 (ASK1) is a member of the mitogen-activated protein kinase kinase kinase (“MAP3K”) family that activates the c-Jun N-terminal protein kinase (“JNK”) and p38 MAP kinase (Ichijo, H., Nishida, E., Irie, K., Dijke, P. T., Saitoh, M., Moriguchi, T., Matsumoto, K., Miyazono, K., and Gotoh, Y. (1997) Science, 275, 90-94). ASK1 is activated by a variety of stimuli including oxidative stress, reactive oxygen species (ROS), LPS, TNF-α, FasL, ER stress, and increased intracellular calcium concentrations (Hattori, K., Naguro, I., Runchel, C., and Ichijo, H. (2009) Cell Comm. Signal. 7:1-10; Takeda, K., Noguchi, T., Naguro, I., and Ichijo, H. (2007) Annu. Rev. Pharmacol. Toxicol. 48: 1-8.27; Nagai, H., Noguchi, T., Takeda, K., and Ichijo, I. (2007) J. Biochem. Mol. Biol. 40:1-6). Phosphorylation of ASK1 protein can lead to apoptosis or other cellular responses depending on the cell type. ASK1 activation and signaling have been reported to play an important role in a broad range of diseases including neurodegenerative, cardiovascular, inflammatory, autoimmune, and metabolic disorders. In addition, ASK1 has been implicated in mediating organ damage following ischemia and reperfusion of the heart, brain, and kidney (Watanabe et al. (2005) BBRC 333, 562-567; Zhang et al., (2003) Life Sci 74-37-43; Terada et al. (2007) BBRC 364: 1043-49).
ROS are reported be associated with increases of inflammatory cytokine production, fibrosis, apoptosis, and necrosis in the kidney. (Singh D K, Winocour P, Farrington K. Oxidative stress in early diabetic nephropathy: fueling the fire. Nat Rev Endocrinol 2011 March; 7(3):176-184; Brownlee M. Biochemistry and molecular cell biology of diabetic complications. Nature 2001 Dec. 13; 414(6865):813-820; Mimura I, Nangaku M. The suffocating kidney: tubulointerstitial hypoxia in end-stage renal disease. Nat Rev Nephrol 2010 November; 6(11):667-678).
Moreover, oxidative stress facilitates the formation of advanced glycation end-products (AGEs) that cause further renal injury and production of ROS. (Hung K Y, et al. N-acetylcysteine-mediated antioxidation prevents hyperglycemia-induced apoptosis and collagen synthesis in rat mesangial cells. Am J Nephrol 2009; 29(3):192-202).
Tubulointerstitial fibrosis in the kidney is a strong predictor of progression to renal failure in patients with chronic kidney diseases (Schainuck L I, et al. Structural-functional correlations in renal disease. Part II: The correlations. Hum Pathol 1970; 1: 631-641.). Unilateral ureteral obstruction (UUO) in rats is a widely used model of tubulointerstitial fibrosis. UUO causes tubulointerstital inflammation, increased expression of transforming growth factor beta (TGF-β), and accumulation of myofibroblasts, which secrete matrix proteins such as collagen and fibronectin. The UUO model can be used to test for a drug's potential to treat chronic kidney disease by inhibiting renal fibrosis (Chevalier et al., Ureteral obstruction as a model of renal interstitial fibrosis and obstructive nephropathy, Kidney International (2009) 75, 1145-1152.
Thus, therapeutic agents that function as inhibitors of ASK1 signaling have the potential to remedy or improve the lives of patients in need of treatment for diseases or conditions such as neurodegenerative, cardiovascular, inflammatory, autoimmune, and metabolic disorders. In particular, ASK1 inhibitors have the potential to treat cardio-renal diseases, including kidney disease, diabetic kidney disease, chronic kidney disease, fibrotic diseases (including lung and kidney fibrosis), dilated cardiomyopathy, respiratory diseases (including chronic obstructive pulmonary disease (COPD) and acute lung injury), acute and chronic liver diseases (such as non-alcoholic steatohepatitis and alcoholic hepatitis).
Various assays for identifying a compound's ability to inhibit ASK1 kinase activity and its usefulness as an ASK1 inhibitor are known in the art and are described, for example, in U.S. Pat. No. 8,742,126.

Liver diseases are acute or chronic damages to the liver based in the duration of the disease. The liver damage may be caused by infection, injury, exposure to drugs or toxic compounds such as alcohol or impurities in foods, an abnormal build-up of normal substances in the blood, an autoimmune process, a genetic defect (such as haemochromatosis), or other unknown causes. Exemplary liver diseases include, but are not limited to, cirrhosis, liver fibrosis, non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), hepatic ischemia reperfusion injury, primary biliary cirrhosis (PBC), and hepatitis, including both viral and alcoholic hepatitis.
Non-alcoholic fatty liver disease (NAFLD) is the build up of extra fat in liver cells that is not caused by alcohol. NAFLD may cause the liver to swell (i.e. steatohepatitis), which in turn may cause scarring (i.e. cirrhosis) over time and may lead to liver cancer or liver failure. NAFLD is characterized by the accumulation of fat in hepatocyes and is often associated with some aspects of metabolic syndrome (e.g. type 2 diabetes mellitus, insulin resistance, hyperlipidemia, hypertension). The frequency of this disease has become increasingly common due to consumption of carbohydrate-rich and high fat diets. A subset (˜20%) of NAFLD patients develop nonalcoholic steatohepatitis (NASH).
NASH, a subtype of fatty liver disease, is the more severe form of NAFLD. It is characterized by macrovesicular steatosis, balloon degeneration of hepatocytes, and/or inflammation ultimately leading to hepatic scarring (i.e. fibrosis). Patients diagnosed with NASH progress to advanced stage liver fibrosis and eventually cirrhosis. The current treatment for cirrhotic NASH patients with end-stage disease is liver transplant.
A study has shown that a significant proportion of diagnosed NASH patients (39%) have not had a liver biopsy to confirm the diagnosis. A greater proportion of diagnosed NASH patients have metabolic syndrome parameters than what is reported in the literature (type-II diabetes mellitus 54%, Obesity 71%, metabolic syndrome 59%). 82% of physicians use a lower threshold value to define significant alcohol consumption compared with practice guideline recommendations. 88% of physicians prescribe some form of pharmacologic treatment for NASH (Vit E: prescribed to 53% of NASH patients, statins: 57%, metformin: 50%). Therefore, the vast majority of patients are prescribed medications despite a lack of a confirmed diagnosis or significant data to support the intervention and alcohol thresholds to exclude NASH are lower than expected.
Another common liver disease is primary sclerosing cholangitis (PSC). It is a chronic or long-term liver disease that slowly damages the bile ducts inside and outside the liver. In patients with PSC, bile accumulates in the liver due to blocked bile ducts, where it gradually damages liver cells and causes cirrhosis, or scarring of the liver. Currently, there is no effective treatment to cure PSC. Many patients having PSC ultimately need a liver transplant due to liver failure, typically about 10 years after being diagnosed with the disease. PSC may also lead to bile duct cancer.
Liver fibrosis is the excessive accumulation of extracellular matrix proteins, including collagen, that occurs in most types of chronic liver diseases. Advanced liver fibrosis results in cirrhosis, liver failure, and portal hypertension and often requires liver transplantation.
Disclosed herein is a method of treating and/or preventing liver disease in a patient in need thereof, comprising administering to the patient a therapeutically effective amount of a form of Compound I as described herein or a composition thereof, optionally in combination with a therapeutically effective amount of a LOXL2 inhibitor. The presence of active liver disease can be detected by the existence of elevated enzyme levels in the blood. Specifically, blood levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), above clinically accepted normal ranges, are known to be indicative of on-going liver damage. Routine monitoring of liver disease patients for blood levels of ALT and AST is used clinically to measure progress of the liver disease while on medical treatment. Reduction of elevated ALT and AST to within the accepted normal range is taken as clinical evidence reflecting a reduction in the severity of the patients on-going liver damage.
In certain embodiments, the liver disease is a chronic liver disease. Chronic liver diseases involve the progressive destruction and regeneration of the liver parenchyma, leading to fibrosis and cirrhosis. In general, chronic liver diseases can be caused by viruses (such as hepatitis B, hepatitis C, cytomegalovirus (CMV), or Epstein Barr Virus (EBV)), toxic agents or drugs (such as alcohol, methotrexate, or nitrofurantoin), a metabolic disease (such as non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), haemochromatosis, or Wilson's Disease), an autoimmune disease (ssuch as Autoimmune Chronic Hepatitis, Primary Biliary Cirrhosis, or Primary Sclerosing Cholangitis), or other causes (such as right heart failure).
Some embodiments described herein are directed to a method of treating liver disease comprising administering a therapeutically effective amount of a form of Compound I as described herein or a pharmaceutical composition as described herein. Liver disease can be classified into 4 stages: F0 indicates no fibrosis; F1 indicates mild fibrosis; F2 indicates moderate fibrosis; F3 indicates severe fibrosis; and F4 indicates cirrhosis. Some embodiments described herein are directed to a method of treating Fibrosis Stage F2 or F3 comprising administering a therapeutically effective amount of a form of Compound I as described herein or a pharmaceutical composition as described herein.
In one embodiment, provided herein is a method for reducing the level of cirrhosis. In one embodiment, cirrhosis is characterized pathologically by loss of the normal microscopic lobular architecture, with fibrosis and nodular regeneration. Methods for measuring the extent of cirrhosis are well known in the art. In one embodiment, the level of cirrhosis is reduced by about 5% to about 100%. In one embodiment, the level of cirrhosis is reduced by at least about 5%, at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45%, at least 50%, at least about 55%, at least about 60%, at least about 65%, at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 95%, or about 100% in the subject.
In certain embodiments, the liver disease is a metabolic liver disease. In one embodiment, the liver disease is non-alcoholic fatty liver disease (NAFLD). NAFLD is associated with insulin resistance and metabolic syndrome (obesity, combined hyperlipidemia, diabetes mellitus (type II) and high blood pressure). NAFLD is considered to cover a spectrum of disease activity, and begins as fatty accumulation in the liver (hepatic steatosis).
It has been shown that both obesity and insulin resistance probably play a strong role in the disease process of NAFLD. In addition to a poor diet, NAFLD has several other known causes. For example, NAFLD can be caused by certain medications, such as amiodarone, antiviral drugs (e.g., nucleoside analogues), aspirin (rarely as part of Reye's syndrome in children), corticosteroids, methotrexate, tamoxifen, or tetracycline. NAFLD has also been linked to the consumption of soft drinks through the presence of high fructose corn syrup which may cause increased deposition of fat in the abdomen, although the consumption of sucrose shows a similar effect (likely due to its breakdown into fructose). Genetics has also been known to play a role, as two genetic mutations for this susceptibility have been identified.
If left untreated, NAFLD can develop into non-alcoholic steatohepatitis (NASH), which is the most extreme form of NAFLD, a state in which steatosis is combined with inflammation and fibrosis. NASH is regarded as a major cause of cirrhosis of the liver of unknown cause. Accordingly, provided herein is a method of treating and/or preventing nonalcoholic steatohepatitis (NASH) in a patient in need thereof, comprising administering to the patient a therapeutically effective amount of form of Compound I as described herein or a composition thereof, optionally in combination with a therapeutically effective amount of a LOXL2 inhibitor.
Also provided herein is a method of treating and/or preventing liver fibrosis in a patient in need thereof, comprising administering to the patient a therapeutically effective amount of an form of Compound I as described herein or a composition thereof, optionally in combination with a therapeutically effective amount of a LOXL2 inhibitor. Liver fibrosis is the excessive accumulation of extracellular matrix proteins including collagen that occurs in most types of chronic liver diseases. In certain embodiments, advanced liver fibrosis results in cirrhosis and liver failure. Methods for measuring liver histologies, such as changes in the extent of fibrosis, lobular hepatitis, and periportal bridging necrosis, are well known in the art.

Inhibition of ASK1 with a form of Compound I and resultant reduction of oxidative stress-induced hepatocyte apoptosis and necrosis, both of which are key mediators of alcoholic liver disease pathogenesis, can improve efficacy and safety in patients with alcoholic liver disease. ASK1 inhibition is expected to reduce pathological hepatocyte apoptosis and necrosis, which correlate with alcoholic liver disease severity. Investigations in rodent models and histopathological studies in humans suggest that lipopolysaccharide (LPS)-induced inflammation and oxidative stress are key drivers of hepatocyte death in alcoholic hepatitis. Ethanol consumption increases intestinal permeability and bacterial translocation to the liver, resulting in LPS-induced hepatic inflammation. Subsequent hepatocellular injury occurs by neutrophil oxidative bursts, and Fas ligand and TNF-α induced hepatocyte apoptosis. In addition, ethanol strongly induces the expression of CYP2E1, which produces reactive oxygen species (ROS) as a by-product of ethanol metabolism, and reduces hepatic antioxidant capacity. Oxidative stress occurs as a result of these changes and directly induces hepatocyte mitochondrial dysfunction and necrosis and also sensitizes hepatocytes to apoptosis induced by TNF-α and FAS ligand [14].
ASK1 is activated by oxidative stress and induces the activation of p38 and JNK kinases, which promote mitochondrial dysfunction leading to apoptosis and necrosis. A potential role for ASK1 in alcoholic liver disease is supported by nonclinical studies demonstrating that oxidative stress, CYP2E1, Fas ligand and TNF-α signaling activate ASK1 in the mouse liver. In addition, Ask1−/− mice are resistant to acute liver injury caused by Fas activation, TNF-α (induced by LPS plus Dgalactosamine), bile duct ligation, or acetaminophen overdose. Moreover, pharmacological inhibition of ASK1 in mice reduces hepatocellular injury and necrosis induced by acetaminophen overdose, as well as cardiac and renal apoptosis and necrosis induced by acute ischemia/reperfusion injury. These effects correlated with reduced activation/phosphorylation of ASK1, p38, and JNK, and reduced mitochondrial dysfunction.
It has been found that ASK1 inhibition does not directly reduce LPS-mediated signaling and cytokine release by macrophages, nor does it reduce oxidative burst by neutrophils. These pathways are considered important mechanisms in the pathophysiology of severe alcoholic hepatitis. Prednisolone is the standard of care for severe alcoholic hepatitis and has been shown to reduce systemic levels of cytokines (i.e. TNF-α, IL-8) and reduce neutrophil activity (oxidative burst) in patients with severe alcoholic hepatitis. The complementary mechanisms of action of a form of Compound I and prednisolone, as well as other therapeutic agents known to be useful for alcoholic hepatitis, suggest a potential benefit could be gained via their combination.
It also has been found that hepatic expression of phospho-p38 (p-p38), a downstream marker of ASK1 activation, are elevated in patients with alcoholic hepatitis. This suggests that treatment with a form of Compound I may benefit patients with alcoholic liver disease.
Mortality due to alcoholic hepatitis is associated with acute loss of liver function and accompanying complications of advanced liver disease, including encephalopathy, sepsis, and/or multiple organ failure, including renal failure. It is believed that the hepatoprotective effects of Compound I can translate into improved liver function and resultant improved mortality in patients with alcoholic liver disease. Early improvement in liver function is associated with better survival (e.g. 1-6 months following presentation). It is not anticipated that ASK1 inhibition will directly ameliorate secondary complications such as those driven by end-stage hemodynamic changes or sepsis.

Some embodiments described herein are methods of treating inflammatory bowel disease (IBD), comprising administering a therapeutically effective amount of a form of Compound I as described herein or a pharmaceutical composition as described herein, optionally in combination with filgotinib. The term “inflammatory bowel disease” or “IBD” as used herein is a collective term describing inflammatory disorders of the gastrointestinal tract, the most common forms of which are ulcerative colitis and Crohn's disease. Other forms of IBD that can be treated with the presently disclosed compounds, compositions and methods include diversion colitis, ischemic colitis, infectious colitis, chemical colitis, microscopic colitis (including collagenous colitis and lymphocytic colitis), atypical colitis, pseudomembranous colitis, fulminant colitis, autistic enterocolitis, indeterminate colitis, Behçet's disease, gastroduodenal CD, jejunoileitis, ileitis, ileocolitis, Crohn's (granulomatous) colitis, irritable bowel syndrome, mucositis, radiation induced enteritis, short bowel syndrome, celiac disease, stomach ulcers, diverticulitis, pouchitis, proctitis, and chronic diarrhea.
Treating or preventing IBD also includes ameliorating or reducing one or more symptoms of IBD. As used herein, the term “symptoms of IBD” refers to detected symptoms such as abdominal pain, diarrhea, rectal bleeding, weight loss, fever, loss of appetite, and other more serious complications, such as dehydration, anemia and malnutrition. A number of such symptoms are subject to quantitative analysis (e.g. weight loss, fever, anemia, etc.). Some symptoms are readily determined from a blood test (e.g. anemia) or a test that detects the presence of blood (e.g. rectal bleeding). The term “wherein said symptoms are reduced” refers to a qualitative or quantitative reduction in detectable symptoms, including but not limited to a detectable impact on the rate of recovery from disease (e.g. rate of weight gain). The diagnosis is typically determined by way of an endoscopic observation of the mucosa, and pathologic examination of endoscopic biopsy specimens.
The course of IBD varies, and is often associated with intermittent periods of disease remission and disease exacerbation. Various methods have been described for characterizing disease activity and severity of IBD as well as response to treatment in subjects having IBD. Treatment according to the present methods are generally applicable to a subject having IBD of any level or degree of disease activity.
Criteria useful for assessment of disease activity in subjects with ulcerative colitis can be found in, e.g., Truelove et al. (1955) Br Med J 2:1041-1048.) Using these criteria, disease activity can be characterized in a subject having IBD as mild disease activity or severe disease activity. Subjects who do not meet all the criteria for severe disease activity, and who exceed the criteria for mild disease activity are classified as having moderate disease activity.
The presently disclosed treatment methods can also be applied at any point in the course of the disease. In certain embodiments, the methods are applied to a subject having IBD during a time period of remission (i.e., inactive disease). In such embodiments, the present methods provide benefit by extending the time period of remission (e.g., extending the period of inactive disease) or by preventing, reducing, or delaying the onset of active disease. In other embodiments, methods may be applied to a subject having IBD during a period of active disease. Such methods provide benefit by reducing the duration of the period of active disease, reducing or ameliorating one or more symptoms of IBD, or treating IBD.
Measures for determining efficacy of treatment of IBD in clinical practice have been described and include, for example, the following: symptom control; fistula closure; extent of corticosteroid therapy required; and, improvement in quality of life. Heath-related quality of life (HRQL) can be assessed using the Inflammatory Bowel Disease Questionnaire (IBDQ), which is extensively used in clinical practice to assess quality of life in a subject with IBD. (See Guyatt et al. (1989) Gastroenterology 96:804-810.) Improvements in any of the foregoing response criteria are specifically provided by the methods of the present disclosure.

Coronary patients being treated for an acute cardiovascular disease event by administration of ASK1 inhibitors often exhibit diseases or conditions that benefit from treatment with other therapeutic agents. These diseases or conditions can be of the cardiovascular nature or can be related to pulmonary disorders, metabolic disorders, gastrointestinal disorders and the like. Additionally, some coronary patients being treated for an acute cardiovascular disease event by administration of an ASK1 inhibitor exhibit conditions that can benefit from treatment with therapeutic agents that are antibiotics, analgesics, and/or antidepressants and anti-anxiety agents.
Cardiovascular related diseases or conditions that can benefit from a combination treatment of ASK1 inhibitors with other therapeutic agents include, without limitation, angina, including stable angina, unstable angina (UA), exercised-induced angina, variant angina, arrhythmias, intermittent claudication, myocardial infarction including non-STE myocardial infarction (NSTEMI), heart failure including congestive (or chronic) heart failure, acute heart failure, or recurrent ischemia.
Therapeutic agents suitable for treating cardiovascular related diseases or conditions include anti-anginals, heart failure agents, antithrombotic agents, antiarrhythmic agents, antihypertensive agents, and lipid lowering agents.
The co-administration of ASK1 inhibitors with therapeutic agents suitable for treating cardiovascular related conditions allows enhancement in the standard of care therapy the patient is currently receiving.
Anti-anginals include beta-blockers, calcium channel blockers, and nitrates. Beta blockers reduce the heart's need for oxygen by reducing its workload resulting in a decreased heart rate and less vigorous heart contraction. Examples of beta-blockers include acebutolol (Sectral), atenolol (Tenormin), betaxolol (Kerlone), bisoprolol/hydrochlorothiazide (Ziac), bisoprolol (Zebeta), carteolol (Cartrol), esmolol (Brevibloc), labetalol (Normodyne, Trandate), metoprolol (Lopressor, Toprol XL), nadolol (Corgard), propranolol (Inderal), sotalol (Betapace), and timolol (Blocadren).
Nitrates dilate the arteries and veins thereby increasing coronary blood flow and decreasing blood pressure. Examples of nitrates include nitroglycerin, nitrate patches, isosorbide dinitrate, and isosorbide-5-mononitrate.
Calcium channel blockers prevent the normal flow of calcium into the cells of the heart and blood vessels causing the blood vessels to relax thereby increasing the supply of blood and oxygen to the heart. Examples of calcium channel blockers include amlodipine (Norvasc, Lotrel), bepridil (Vascor), diltiazem (Cardizem, Tiazac), felodipine (Plendil), nifedipine (Adalat, Procardia), nimodipine (Nimotop), nisoldipine (Sular), verapamil (Calan, Isoptin, Verelan), and nicardipine.
Agents used to treat heart failure include diuretics, ACE inhibitors, vasodilators, and cardiac glycosides. Diuretics eliminate excess fluids in the tissues and circulation thereby relieving many of the symptoms of heart failure. Examples of diuretics include hydrochlorothiazide, metolazone (Zaroxolyn), furosemide (Lasix), bumetanide (Bumex), spironolactone (Aldactone), and eplerenone (Inspra).
Angiotensin converting enzyme (ACE) inhibitors reduce the workload on the heart by expanding the blood vessels and decreasing resistance to blood flow. Examples of ACE inhibitors include benazepril (Lotensin), captopril (Capoten), enalapril (Vasotec), fosinopril (Monopril), lisinopril (Prinivil, Zestril), moexipril (Univasc), perindopril (Aceon), quinapril (Accupril), ramipril (Altace), and trandolapril (Mavik).
Vasodilators reduce pressure on the blood vessels by making them relax and expand. Examples of vasodilators include hydralazine, diazoxide, prazosin, clonidine, and methyldopa. ACE inhibitors, nitrates, potassium channel activators, and calcium channel blockers also act as vasodilators.
Cardiac glycosides are compounds that increase the force of the heart's contractions. These compounds strengthen the pumping capacity of the heart and improve irregular heartbeat activity. Examples of cardiac glycosides include digitalis, digoxin, and digitoxin.
Antithrombotics inhibit the clotting ability of the blood. There are three main types of antithrombotics—platelet inhibitors, anticoagulants, and thrombolytic agents. Platelet inhibitors inhibit the clotting activity of platelets, thereby reducing clotting in the arteries. Examples of platelet inhibitors include acetylsalicylic acid (aspirin), ticlopidine, clopidogrel (plavix), dipyridamole, cilostazol, persantine sulfinpyrazone, dipyridamole, indomethacin, and glycoprotein llb/llla inhibitors, such as abciximab, tirofiban, and eptifibatide (Integrelin). Beta blockers and calcium channel blockers also have a platelet-inhibiting effect.
Anticoagulants prevent blood clots from growing larger and prevent the formation of new clots. Examples of anticoagulants include bivalirudin (Angiomax), warfarin (Coumadin), unfractionated heparin, low molecular weight heparin, danaparoid, lepirudin, and argatroban.
Thrombolytic agents act to break down an existing blood clot. Examples of thrombolytic agents include streptokinase, urokinase, and tenecteplase (TNK), and tissue plasminogen activator (t-PA).
Antiarrhythmic agents are used to treat disorders of the heart rate and rhythm. Examples of antiarrhythmic agents include amiodarone, quinidine, procainamide, lidocaine, and propafenone. Cardiac glycosides and beta blockers are also used as antiarrhythmic agents.
Antihypertensive agents are used to treat hypertension, a condition in which the blood pressure is consistently higher than normal. Hypertension is associated with many aspects of cardiovascular disease, including congestive heart failure, atherosclerosis, and clot formation.
Examples of antihypertensive agents include alpha-1-adrenergic antagonists, such as prazosin (Minipress), doxazosin mesylate (Cardura), prazosin hydrochloride (Minipress), prazosin, polythiazide (Minizide), and terazosin hydrochloride (Hytrin); beta-adrenergic antagonists, such as propranolol (Inderal), nadolol (Corgard), timolol (Blocadren), metoprolol (Lopressor), and pindolol (Visken); central alpha-adrenoceptor agonists, such as clonidine hydrochloride (Catapres), clonidine hydrochloride and chlorthalidone (Clorpres, Combipres), guanabenz Acetate (Wytensin), guanfacine hydrochloride (Tenex), methyldopa (Aldomet), methyldopa and chlorothiazide (Aldoclor), methyldopa and hydrochlorothiazide (Aldoril); combined alpha/beta-adrenergic antagonists, such as labetalol (Normodyne, Trandate), Carvedilol (Coreg); adrenergic neuron blocking agents, such as guanethidine (Ismelin), reserpine (Serpasil); central nervous system-acting antihypertensives, such as clonidine (Catapres), methyldopa (Aldomet), guanabenz (Wytensin); anti-angiotensin II agents; ACE inhibitors, such as perindopril (Aceon) captopril (Capoten), enalapril (Vasotec), lisinopril (Prinivil, Zestril); angiotensin-II receptor antagonists, such as Candesartan (Atacand), Eprosartan (Teveten), Irbesartan (Avapro), Losartan (Cozaar), Telmisartan (Micardis), Valsartan (Diovan); calcium channel blockers, such as verapamil (Calan, Isoptin), diltiazem (Cardizem), nifedipine (Adalat, Procardia); diuretics; direct vasodilators, such as nitroprusside (Nipride), diazoxide (Hyperstat IV), hydralazine (Apresoline), minoxidil (Loniten), verapamil; and potassium channel activators, such as aprikalim, bimakalim, cromakalim, emakalim, nicorandil, and pinacidil.

1.1 Compound I Form I
Compound I Form I is an anhydrous form of Compound I, and it is contemplated to be the most thermodynamically stable polymorph of Compound I obtained from most organic solvents/solvent mixtures except for DCM and aqueous mixtures at greater than 0.6 water activity at ambient conditions.
Compound I Form I is crystalline by XRPD (
Initially, Compound I Form I was isolated using the following procedure:
5-(4-Cyclopropyl-1H-imidazol-1-yl)-2-fluoro-4-methylbenzoic acid hydrochloride (30 g, 102 mmol) was suspended in anhydrous 1,2-dichloromethane (900 mL) at room temperature. Oxalyl chloride (18 ml, 205 mmol) was added while stirring under nitrogen, followed by N,N-dimethylformamide (0.783 ml, 10.2 mmol). The mixture was stirred for about 4 hr at room temperature, and then the solvent was removed under reduced pressure. The residue was dissolved in about 600 mL anhydrous dichloromethane. 6-(4-Isopropyl-4H-1,2,4-triazol-3-yl)pyridin-2-amine (22.9 g, 113 mmol) and 4-dimethylaminopyridine (12.5 g, 102 mmol) were rapidly added with stirring under nitrogen. The reaction was stirred for about 2 hours at room temperature and the dichloromethane was evaporated. The residue was dissolved in 500 mL water and solid NaHCO3 was added until the pH of the mixture was about 7. Dichloromethane was added (about 500 mL) and the layers were separated. The aqueous layer was extracted with dichloromethane (2×300 mL). The combined organics were washed with water (2×200 mL), dried over MgSO4, filtered and concentrated. The residue was dissolved in a minimum amount of THF, and water was added slowly until a thick slurry was formed. The solids were collected by filtration, washed with water, and dried.
The solids obtained (about 72 g) were recrystallized from hot EtOH (5 ml/g solid) and the solids collected by filtration, washed with 2:1 diethyl ether/EtOH, followed by diethyl ether and dried.
Compound I Form I can be isolated from a variety of solvent systems including (but not limited to): MeOH/water, MeOH/MTBE, iPrOAc/n-heptane, MTBE/n-heptane, and EtOH/n-heptane. The following two exemplary methods can be suitable for isolating Compound I Form I.
Method 1:
-
- Solution of Compound I in DCM is solvent exchanged to EtOH (about 3 mL/g with respect to input Compound I) and heated to about 50° C.
- Heptane (about 6.7 mL/g with respect to input Compound I) is added over about 1 h, and the resulting slurry is aged at about 50° C. for about 1 h
- The slurry is cooled to about 0° C. at about 10° C./h and aged at about 0° C. for about overnight
- The slurry is filtered and the wet cake is rinsed with 2 mL/g (with respect to g input Compound I) 1:2 v/v EtOH/heptane
- The isolated material is dried in a vacuum oven at about 45° C. to obtain Compound I Form I.
Method 2:
Due to the low solubility of Compound I in EtOH (about 20 mg/mL), a slurry of Compound I Form I is typically formed after performing the solvent exchange as outlined above. Solubility studies of Compound I in DCM/EtOH mixtures at elevated temperature were performed to determine the solubility range in the solvent swap that would accommodate seeding. The process outlined below was developed using this data aiming at about 10-20% v/v DCM remaining at the time of seeding. The crystallization was then continued in line with Method 1 outlined above. After filtration, the Form I solids are dried in a vacuum oven at about 45-50° C. The following steps can be performed to isolate Compound I Form I:
-
- Final organic solution of Compound I in DCM is partially solvent exchanged to about 7.5 mL/g 20% v/v DCM/EtOH (with respect to input g Compound I) and the solution is seeded at about 50° C. with about 0.5 wt/wt % Compound I Form I and a seed bed is allowed to form over about 0.5 h
- Distillation is continued to provide about 3.3 mL/g total reactor volume of primarily EtOH as solvent
- Heptane (about 6.7 mL/g with respect to input g Compound I) is added over about 2 h, and the slurry is aged at about 50° C. for about 0.5 h
- The slurry is cooled to about 20° C. over about 1 h and aged at about 20° C. for about 0.5 h
- The slurry is filtered and the wet cake is rinsed with 2 mL/g (with respect to input g Compound I) 1:2 v/v EtOH/Heptane
- The isolated material is dried in a vacuum oven at about 45° C. to obtain Compound I Form I.
1.2 Compound I Form II and Compound I Form V
Compound I Form II was discovered during isolation of Compound I from DCM/n-heptane. Experimental XRPD showed that Form V is a labile solvate and the XRPD was not phase-pure. Air-drying at RT showed Form V converting to Form II and the presence of at least one intermediate form. Form V has only been truly isolated by growth of single crystals.
Compound I Form II is a desolvated polymorph of Compound I (
Compound I Form V can be transiently observed by XRPD by analyzing the wet cake of Compound I derived from crystallizations performed in DCM or DCM/n-heptane mixtures (
Compound I Form II and Compound I Form V were also observed during a stable form screen of Compound I Form I in DCM (see Section 2.1 below). A slurry of Compound I Form I in DCM after about 24 hours produced a mixture of Forms II and V by XRPD. After about 14 days, the slurry was a mixture of Compound I Form II and Compound I Form V. The DSC data shows an endotherm with onset at about 91° C. and an endotherm with onset at about 164° C. (
A single crystal of Compound I Form V was obtained during a stable form screen (Section 2.1 below) which confirmed the structure of Compound I DCM solvate. The XRPD of freshly acquired wet cake samples from DCM suspension are similar to the calculated powder pattern for Form V; the differences in the calculated powder pattern and experimental pattern can be attributed to partial de-solvation to an intermediate form (full drying of the DCM wet cake at RT yields Compound I Form II) and temperature anisotropy. If the postulated intermediate form from DCM is real, it is too poorly defined to merit a Form designation. Table 2 summarizes the Single Crystal Data for Compound I Form V.
Competition slurries between Compound I Form I and Compound I Form II revealed that Compound I Form I is the more stable polymorph in solvents lacking DCM at ambient temperature. For example, a mixture of Forms I and II in MeOH/water produces Form I while a mixture of the two forms slurried in DCM/n-heptane produces Form II.
1.3 Compound I Form III
Compound I Form III is a hydrated form that was obtained by suspending Compound I (about 100 mg) in methanol/water (0.215:0.785) mixture (1 mL) at about 50° C. for about 7 days (
1.4 Compound I Form IV
Compound I Form IV is a hydrate that was observed to precipitate out of solution when 3 volumes of water were charged to a solution of Compound I in 4 volumes of methanol. The following procedure was used to obtain Form IV: Compound I (1 g) was dissolved in 4 mL of MeOH by heating to about 40° C. Water (3 mL) was charged to generate a thick slurry. Additional water (11.6 mL) was charged to the mixture to obtain a 0.9 water activity. The resulting slurry was cooled to room temperature and filtered. The wet cake was dried in a vacuum oven at room temperature to obtain Compound I Form IV (0.98 g).
Compound I Form IV can be characterized by an X-ray powder diffractogram comprising the following peaks: 7.2, 12.6, 13.8, 19.3, 25.9, and 28.6° 2θ±0.2° 2θ (
1.5 Compound I Form VI
Compound I Form VI was generated by fast evaporation under vacuum from a number of different solvents or solvent mixtures (acetonitrile, ethanol, tetrahydrofuran, methanol/methyl isobutyl ketone and methanol/1-butanol). Initially, Compound I Form VI was isolated in an impure state and these samples were contaminated with traces of Compound I Form I or other polymorphs. However, the pure form was isolated after heating the Compound I Form II at 180° C. for about 10 min (
DSC trace of Compound I Form VI shows single sharp endotherm with onset at about 202° C. (
1.6 Compound I Form VII
Compound I Form VII was generated by exposing Compound I Form IV (which was made as discussed above), to low relative humidity conditions (
1.7 Compound I Form VIII
Compound I Form VIII is an unstable hydrate which rapidly loses water and converts to Compound I Form VI at ambient conditions. Compound I Form VIII was obtained after equilibration of unsolvated Compound I Form VI in humidity chamber at 90% RH and from the slurry of Compound I Form VI in EtOH/water at 0.9 water activity (
1.8 Compound I Form IX
Compound I Form IX is an acetic acid solvate. Compound I Form IX was obtained by dissolving Compound I in glacial acetic acid and stirring at ambient temperature (
1.9 Amorphous Compound I
Amorphous Compound I was obtained by fast vacuum evaporation of DCM solution, fast evaporation of methanol solution, and by drying Compound I Form III at 110° C. (
2.1 Stable Form Screen of Compound I
Starting from Compound I Form I, a stable form screen of Compound I was performed. Compound I Form I was suspended with stirring in capped glass vials at RT. Samples from the suspensions were centrifuged/filtered and the isolated solids and liquids were analyzed. Solids were analyzed by XRPD and liquids were analyzed for solubility by TGA. Sampling and analysis were performed after one day and greater than fourteen days.
Table 3 presents the solvents which were investigated in this study. In this study, Compound I Form II and Compound I Form V were observed. In addition, crystals suitable for single crystal X-ray analysis of Compound I Form V were obtained from DCM and crystals suitable for single crystal X-ray analysis of Compound I Form I were obtained from methanol (discussed above). No new polymorphs of Compound I were discovered from the stable form screen.
3.1 Salt and Co-Crystal Screen of Compound I
A salt/co-crystal screen was performed using high throughput and manual techniques, and exemplary salts were obtained as described below.
3.1.1 Compound I Esylate Form I
60.4 mg Compound I was slurried in 1 mL ethanol at approximately 60° C. Then, 12 μL ethanesulfonic acid (about 1.1 equivalents) was added to the mixture, and the sample clarified. The sample was allowed to cool to ambient temperature and allowed to evaporate to dryness. The XRPD pattern of the obtained solids is presented in

4.1 Compound I for Alcoholic Hepatitis
Hepatic p-p38 expression in alcoholic liver biopsies was quantified based on immunohistochemistry using a rabbit monoclonal antibody against human p-p38. Thresholds for low, medium and high staining and the percentage of cells within each category were determined. Staining intensity was expressed as a Histologic Score (HS) that considers the distribution and intensity of staining (range, 0 to 300). Liver biopsies were also graded according to the Alcoholic Hepatitis Histologic Score (AHHS). Correlations between the intensity of p-p38 expression and clinical and histologic characteristics in alcoholic hepatitis were determined, and compared with patients with NASH (n=60) and primary sclerosing cholangitis (PSC, n=105).
Liver biopsies from 9 alcoholic hepatitis patients were studied (median age, 42 years; 45% male; median Model for End-Stage Liver Disease (MELD), 24 (IQR 23-27); 44% with bridging fibrosis or cirrhosis; and two deaths, 22%). All alcoholic hepatitis biopsies were p-p38-immunoreactive (median HS, 124; range 100154); significantly greater than those observed in patients with non-alcoholic steatohepatitis (13.4 [IQR 4.3-30.3]) and PSC (54.1 [27.1-76.9]; both P<0.001). In alcoholic hepatitis, p-p38 was detected multi-focally in hepatocyte clusters. Hepatocyte p-p38 expression was diffusely cytoplasmic and/or strongly nuclear. In ballooned hepatocytes, p-p38 was localized to cytoplasmic aggregates consistent with Mallory bodies. Inflammatory infiltrates staining positive for p-p38 were predominantly macrophages; polymorphonuclear neutrophils (PMNs) did not express p-p38. Reactive bile ducts also contained occasional cytoplasmic and/or nuclear p-p38. p-p38 expression was correlated with MELD (ρ=0.67; P=0.047) and hematocrit (ρ=0.73; P=0.025), and inversely associated with the serum bicarbonate concentration (ρ=−0.69; P=0.038), but not other standard laboratory parameters. p-p38 expression was higher in hepatocellular than canalicular or ductular bilirubinostasis (median HS; 133.5 vs. 103; P=0.020). However, p-p38 staining intensity was not associated with the total AHHS or other histologic variables.
The results show that hepatic expression of p-p38 is correlated with MELD and other markers of alcoholic hepatitis severity, suggesting that ASK1 inhibition may have therapeutic benefit in patients with this disease.
