In some embodiments, the patient has had a liver biopsy. In some embodiments, the method further comprises obtaining the results of a liver biopsy.

[0036] In some embodiments, provided is a method of impeding or slowing the progression of NAFLD to NASH in a patient (e.g., a human patient) in need thereof comprising administering a therapeutically effective amount of a solid dispersion disclosed herein.

[0037] Compound I is preferentially distributed to the liver, which, without being bound by theory, would allow the compound to reach its FXR target in the liver with fewer off- target adverse effects. For example, Compound I has an approximately 20-fold higher concentration in the liver than in the plasma, kidney, lungs, heart, and skin. This trait would likely be particularly beneficial for vulnerable populations, such as children, the elderly, and people with comorbidities.

[0038] Further, pruritus is a well -documented adverse effect of several FXR agonists and can result in patient discomfort, a decrease in patient quality of life, and an increased likelihood of ceasing treatment. Pruritus is particularly burdensome for indications, such as those described herein, including NASH, for which chronic drug administration is likely. The tissue specificity of Compound I, in particular the preference for liver over skin tissue is a striking and unpredicted observation that makes it more likely that the compound will not cause pruritus in the skin, a theory that has been substantiated by human trials thus far.

[0039] In some embodiments, provided is a method of treating a liver disorder in a patient in need thereof (e.g., a human patient) with Compound I that preferentially distributes in liver tissue over one or more of kidney, lung, heart, and skin tissues, the method comprising administering a therapeutically effective amount of Compound I, wherein Compound I is formulated as a solid dispersion disclosed herein.

[0040] In some embodiments, provided herein is a method of treating a liver disorder in a patient in need thereof comprising administering a therapeutically effective amount of Compound I, wherein Compound I is formulated as a solid dispersion disclosed herein and wherein Compound I does not activate TGR5 signaling. In some embodiments, the level of an FXR-regulated gene is increased. In some embodiments, the level of small heterodimer partner (SHP), bile salt export pump (BSEP) and fibroblast growth factor 19 (FGF-19) is increased. In some embodiments, the liver disorder is NASH.

[0041] In some embodiments, provided herein is a method of reducing liver damage comprising administering a therapeutically effective amount of Compound I, wherein Compound I is formulated as a solid dispersion disclosed herein, to an individual in need thereof. In some embodiments, fibrosis is reduced. In some embodiments, the level of expression of one or more markers for fibrosis is reduced. In some embodiments, the level of Ccr2, Collal, Colla2, Colla3, Cxcr3, Den, Hgf, Illa, Inhbe, Lox, Loxll, Loxl2, Loxl3, Mmp2, pdgfb, Plau, Serpinel, Perpinhl, Snai, Tgfbl, Tgfb3, Thbsl, Thbs2, Timp2, and/or Timp3 expression is reduced. In some embodiments, the level of collagen is reduced. In some embodiments, the level of collagen fragments is reduced. In some embodiments, the level of expression of the fibrosis marker is reduced at least 2, at least 3, at least 4, or at least 5-fold. In some embodiments, the level of expression of the fibrosis marker is reduced about 2-fold, about 3-fold, about 4-fold, or about 5-fold. [0042] In some embodiments, provided herein is a method of reducing liver damage comprising administering a therapeutically effective amount of Compound I, wherein Compound I is formulated as a solid dispersion disclosed herein, to an individual in need thereof. In some embodiments, inflammation is reduced. In some embodiments, one or more markers of inflammation are reduced. In some embodiments, the level of expression of Adgrel, Ccr2, Ccr5, 111A, and/or Tlr4 is reduced. In some embodiments, the level of expression of the inflammation marker is reduced at least 2-, at least 3-, at least 4-, or at least 5-fold. In some embodiments, the level of expression of the fibrosis marker is reduced about 2-fold, about 3-fold, about 4-fold, or about 5-fold.

[0043] In some embodiments, the administration does not result in pruritus in the patient greater than Grade 2 in severity. In some embodiments, the administration does not result in pruritus in the patient greater than Grade 1 in severity. In some embodiments, the administration does not result in pruritus in the patient. The grading of adverse effects is known. According to Version 5 of the Common Terminology Criteria for Adverse Events (published November 27, 2017), Grade 1 pruritus is characterized as “Mild or localized; topical intervention indicated.” Grade 2 pruritus is characterized as “Widespread and intermittent; skin changes from scratching (e.g., edema, papulation, excoriations, lichenification, oozing/crusts); oral intervention indicated; limiting instrumental ADL.” Grade 3 pruritus is characterized as “Widespread and constant; limiting self care ADL or sleep; systemic corticosteroid or immunosuppressive therapy indicated.” Activities of daily living (ADL) are divided into two categories: “Instrumental ADL refer to preparing meals, shopping for groceries or clothes, using the telephone, managing money, etc.,” and “Self care ADL refer to bathing, dressing and undressing, feeding self, using the toilet, taking medications, and not bedridden.”

[0044] Accordingly, in some embodiments, provided is a method of treating a liver disorder in a patient (e.g., a human patient) in need thereof with Compound I that does not result in detectable pruritus in the patient, the method comprising administering to the patient in need thereof a therapeutically effective amount of Compound I, wherein Compound I is formulated as a solid dispersion disclosed herein.

[0045] In some embodiments, the patient is a human. Obesity is highly correlated with NAFLD and NASH, but lean people can also be affected by NAFLD and NASH.

Accordingly, in some embodiments, the patient is obese. In some embodiments, the patient is not obese. Obesity can be correlated with or cause other diseases as well, such as diabetes mellitus or cardiovascular disorders. Accordingly, in some embodiments, the patient also has diabetes mellitus and/or a cardiovascular disorder. Without being bound by theory, it is believed that comorbidities, such as obesity, diabetes mellitus, and cardiovascular disorders can make NAFLD and NASH more difficult to treat. Conversely, the only currently recognized method for addressing NAFLD and NASH is weight loss, which would likely have little to no effect on a lean patient.

[0046] The risk for NAFLD and NASH increases with age, but children can also suffer from NAFLD and NASH, with literature reporting of children as young as 2 years old (Schwimmer, et al., Pediatrics, 2006, 118:1388-1393). In some embodiments, the patient is 2- 17 years old, such as 2-10, 2-6, 2-4, 4-15, 4-8, 6-15, 6-10, 8-17, 8-15, 8-12, 10-17, or 13-17 years old. In some embodiments, the patient is 18-64 years old, such as 18-55, 18-40, 18-30, 18-26, 18-21, 21-64, 21-55, 21-40, 21-30, 21-26, 26-64, 26-55, 26-40, 26-30, 30-64, 30-55, 30-40, 40-64, 40-55, or 55-64 years old. In some embodiments, the patient is 65 or more years old, such as 70 or more, 80 or more, or 90 or more.

[0047] NAFLD and NASH are common causes of liver transplantation, but patients that already received one liver transplant often develop NAFLD and/or NASH again. Accordingly, in some embodiments, the patient has had a liver transplant.

[0048] In some embodiments, the patient’s alkaline phosphatase, gamma-glutamyl transferase (GGT), alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) levels are elevated. In some embodiments, the GGT, ALT, and/or AST levels are elevated prior to treatment with a solid dispersion disclosed herein. In some embodiments, the patient’s ALT level is about 2-4-fold greater than the upper limit of normal levels. In some embodiments, the patient’s AST level is about 2-4-fold greater than the upper limit of normal levels. In some embodiments, the patient’s GGT level is about 1.5-3-fold greater than the upper limit of normal levels. In some embodiments, the patient’s alkaline phosphatase level is about 1.5-3-fold greater than the upper limit of normal levels. Methods of determining the levels of these molecules are well known. Normal levels of ALT in the blood range from about 7-56 units/liter. Normal levels of AST in the blood range from about 10-40 units/liter. Normal levels of GGT in the blood range from about 9-48 units/liter. Normal levels of alkaline phosphatase in the blood range from about 53-128 units/liter for a 20- to 50-year-old man and about 42-98 units/liter for a 20- to 50-year-old woman.

[0049] Accordingly, in some embodiments, a solid dispersion disclosed herein, reduces level of AST, ALT, and/or GGT in an individual having elevated AST, ALT, and/or GGT levels. In some embodiments, the level of ALT is reduced at least 2-, at least 3-, at least 4-, or at least 5-fold. In some embodiments, the level of ALT is reduced about 2- to about 5-fold. In some embodiments, the level of AST is reduced at least 2-, at least 3-, at least 4-, or at least 5-fold. In some embodiments, the level of AST is reduced about 1.5 to about 3-fold. In some embodiments, the level of GGT is reduced at least 2, at least 3, at least 4, or at least 5-fold. In some embodiments, the level of GGT is reduced about 1.5 to about 3-fold.

[0050] In some embodiments, administration of a solid dispersion disclosed herein, to a subject results in a reduced NAFLD Activity Score (NAS). For example, in some embodiments, steatosis, inflammation, and/or ballooning is reduced upon treatment. In some embodiments, the compounds disclosed herein reduce liver fibrosis. In some embodiments, the compounds reduce serum triglycerides. In some embodiments, the compounds reduce liver triglycerides.

[0051] In some embodiments, the patient is at risk of developing an adverse effect prior to administering a solid dispersion disclosed herein. In some embodiments, the adverse effect is an adverse effect which affects the kidney, lung, heart, and/or skin. In some embodiments, the adverse effect is pruritus.

[0052] In some embodiments, the patient has had one or more prior therapies. In some embodiments, the liver disorder progressed during the therapy. In some embodiments, the patient has had one or more prior therapies with another FXR agonist other that Compound I. In some embodiments, the patient suffered from pruritus during at least one of the one or more prior therapies.

[0053] In some embodiments, the therapeutically effective amount is below the level that induces an adverse effect in the patient, such as below the level that induces pruritus, such as grade 2 or grade 3 pruritus.

The particular materials and conditions described hereunder are intended to exemplify particular aspects of embodiments disclosed herein and should not be construed to limit the reasonable scope thereof.

Example 1. Preparation of Solid Dispersions by Hot-Melt Extrusion

[0055] A mixture of 35 g Compound I and 105 g vinylpyrrolidone-vinyl acetate copolymer (sold under the trademark Kollidon® VA 64) (API: polymer, w/w = 1:3), a mixture of 35 g Compound I and 105 g vinylcaprolactam-vinyl acetate-ethylene glycol copolymer (sold under the trademark Soluplus®) (API: polymer, w/w = 1:3), and a mixture of 35 g Compound I and 105 g hydroxypropyl methylcellulose acetate succinate (HPMCAS- LG) (API: polymer, w/w = 1:3) were hot-melt extruded on a Leistritz (ZSE 18HP) extruder. The extrusion conditions and properties of the resulting solid dispersions are provided in Table 1.

TABLE 1

a: Transparent yellow solid b: Opaque white solid c: Opaque gray solid

[0056] The resulting extrudates wrere milled, sieved, and measured by differential scanning calorimetry (DSC). The DSC data suggests that Compound I was substantially amorphous in those solid dispersions.

[0057] Impurities in various samples (Compound I; a physical mixture of Compound I and Kollidon® VA 64; a physical mixture of Compound I and Soluplus®; Compound I/Kollidon® VA 64 solid dispersion; and Compound I/Soluplus® solid dispersion) were determined by High-performance Liquid Chromatography (HPLC). The results are provided in Table 2. TABLE 2

Example 2. Solubility Study

[0058] Compound I , Compound I/Kollidon® VA 64 solid dispersion prepared according to Example 1, and Compound I/Soluplus® solid dispersion prepared according to Example 1 were dissolved in phosphate buffer (pH = 6.8) and the resulting mixtures were agitated at 37 °C. Samples were taken at 15 minutes, 30 minutes, 60 minutes, 120 minutes, 4 hours, 8 hours, and 24 hours. Each sample was filtered and the resulting filtrate was measured by ultraviolet- visible spectroscopy to determine the concentration of Compound I. The results are provided in Table 3 As shown in Table 3, Compound I had low solubility in phosphate buffer.

Compound 1/ Kollidon® VA 64 solid dispersion and Compound I/Soluplus® solid dispersion both showed significantly improved solubility compared with Compound I. Compound I/V A 64 solid dispersion showed the best solubility.

TABLE 3

Example 3. Bioavailability Study

[0059] Compound I/Kollidon® VA 64 solid dispersion prepared according to Example 1 was blended with excipients. The mixture was compressed to manufacture tablets of 5-mg and 25-mg strengths. Compound I, which was not in a solid dispersion, was also blended with excipients to manufacture capsules of 25-mg strength. Both types of tablets showed good stability under accelerated and long-term conditions and dissolution results were well within the immediate release requirements of NLT 70% of the label claim of Compound I in 45 minutes. Tablets of 25-mg strength and capsules containing 25 mg of Compound I were tested in dog pharmacokinetic study. The results are shown in FIG. 1. Mean percent bioavailability (F%) of the tablet was between 30% and 40% under different pHs and feeding conditions; while the bioavailability (F%) of the capsule was only between 1.5% and 3%.

Example 4. Bioavailability Study

[0060] A Phase 1 randomized, open-label study was conducted in 16 healthy subjects. PK samples of Compound I were obtained up to 72 hours after single oral administration of: 1) 5- mg strength and 25-mg strength tablets (prepared according to Example 3) in 16 fasted subjects ; 2) 25-mg strength capsule (containing 25 mg Compound I not in a solid dispersion) in 8 fasted subjects; and 3) 5-mg strength tablet (prepared according to Example 3) in 8 subjects after a high-fat, high calorie meal. Safety and tolerability of the tablets and capsule were also assessed.

[0061] Compound I tablet was rapidly absorbed under the fasted condition; absorption was more gradual for Compound I capsule. Plasma Cmax and AUC increased approximately dose proportionally in the range of 5 mg to 25 mg for the tablets. Systemic exposure of Compound I in fasted subjects was ~4-fold higher for 25-mg strength tablet vs. 25-mg strength capsule. Food slowed Compound I tablet absorption, with increased Tmax and decreased Cmax relative to fasted, but did not significantly impact total systemic exposure. There were no notable trends in adverse events (AE) between treatment groups, across dose levels or formulation. Most AEs were mild in severity and considered not related or unlikely related to study drug.

[0062] Compound I solid dispersion tablets achieved faster absorption and higher systemic exposure compared to capsules containing Compound I. They can be administered without regard to food. Compound I was safe and well tolerated in all treatment groups.
