Methodology: 
This Phase 3, double-blind, randomized, placebo-controlled, multicenter international study will evaluate the 
efficacy and safety of OCA in subjects with a biopsy-confirmed diagnosis of cirrhosis (based on a fibrosis score 
of 4 using the NASH CRN scoring system) due to NASH (determined by central reading of liver histology).  
Subjects with hepatic decompensation or CP Class B or Class C cirrhosis are excluded.  Subjects who progress to 
CP Class B or Class C during the study will discontinue investigational product but are expected to be followed 
through to study closure (or at the discretion of the Sponsor).  
Double-Blind Phase (18 Months):  Subjects will be screened for a period of up to 12 weeks before entering the 
study.  Subjects who meet the entry requirements will be randomized in a 1:1:1 ratio to one of the three treatment 
arms:  once daily dosing of OCA 10 mg, OCA 10 mg → 25 mg (ie, OCA 10 mg with uptitration to OCA 25 mg 
at Month 3), or placebo, in conjunction with the standard of care.  Uptitration will be determined based on the 
laboratory criteria and safety and tolerability assessments completed prior to Month 3. 
Randomized subjects will be stratified by the presence of type 2 diabetes at enrollment (yes or no).  
Investigational product (ie, OCA or placebo) will be taken orally, with water, once daily.  Efficacy, safety, and 
laboratory assessments will be evaluated at clinical visits at Day 1, monthly for the initial 6 months (Month 1 
through Month 6 Visits), Month 9, Month 12, Month 15, and Month 18. 
Open-Label Extension (up to 12 Months):  Subjects who complete the Double-Blind Month 18 Visit and 
continue to receive investigational product are eligible to enroll into the OLE.  All subjects will receive OCA 
upon entry into the OLE.  Subjects randomized to placebo in the Double-Blind Phase will be re-randomized to 
either OCA 10 mg or OCA 10 mg → 25 mg (ie, OCA 10 mg for the first 3 months of the OLE prior to uptitrating 
to OCA 25 mg at OLE Month 3).  Uptitration will be determined based on the same criteria and assessments as 
employed in the Double-Blind Phase.  Subjects randomized to OCA (10 mg or 10 mg → 25 mg dose) during the 
Double-Blind Phase will continue the same dosing regimen they received at the end of the Double-Blind Phase; 
however, they will undergo dummy titration to maintain study blind until all subjects complete the Double-Blind 
Phase and the database is locked.

CP = Child-Pugh; CRN = clinical research network; NASH = nonalcoholic steatohepatitis; OCA = obeticholic acid; OLE = open-label 
extension; QD = once daily. 
a Subjects who meet the entry requirements will be randomized in a 1:1:1 ratio to one of the three treatment arms:  once daily dosing of OCA 
10 mg, OCA 10 mg → 25 mg (ie, OCA 10 mg with uptitration to OCA 25 mg at Month 3), or placebo, in conjunction with the standard of 
care. 
b All subjects will receive OCA upon entry into the OLE:  Subjects who received placebo during the Double-Blind Phase will be 
re-randomized to either OCA 10 mg or OCA 10 mg → 25 mg (ie, OCA 10 mg with uptitration to OCA 25 mg at OLE Month 3).  Subjects 
who received OCA during the Double-Blind Phase will continue the same dosing regimen they received at the end of the Double-Blind 
Phase. 
c During the OLE period, subjects will return for site visits at Months 1, 2, 3, 4, 5, 6, 9, and 12.   
 
Notes:   
• 
Subjects with cirrhosis (based on a NASH CRN fibrosis score 4) due to NASH (determined by central reading of liver histology) will be 
enrolled in the study.  Subjects with hepatic decompensation or CP Class B or CP Class C cirrhosis are excluded.   
• 
Two screening visit assessments will be performed.  Screening Visit 1 will occur no more than 12 weeks prior to Day 1, and Screening 
Visit 2 will occur at least 4 weeks after Screening Visit 1.  
• 
Randomized subjects will be stratified by the presence of type 2 diabetes at enrollment (yes or no). 
• 
The study will remain blinded until all subjects complete the Double-Blind Phase and the database is locked.  To maintain blinding, all 
investigational product (placebo and OCA) tablets and bottles will be identical.

Number of Subjects (planned):  Approximately 900 subjects will be enrolled in the study. 
Diagnosis and Main Criteria for Inclusion:  
Inclusion Criteria 
1. 
Subjects ≥18 years of age  
2. Subjects with a confirmed diagnosis of NASH and a fibrosis score of 4 based upon the NASH CRN scoring 
system determined by central reading of a liver biopsy obtained no more than 12 months before Day 1. 
3. Contraception:  Female subjects of childbearing potential must use ≥1 effective method (≤1% failure rate) of 
contraception during the study until 4 weeks following the last dose of investigational product (including 
OLE doses).  Female subjects are considered as being of childbearing potential, ie, fertile, following 
menarche and until becoming postmenopausal, unless permanently sterile. Permanent sterilization methods 
include hysterectomy, bilateral salpingectomy, and bilateral oophorectomy. A postmenopausal state is 
defined as no menses for 12 months without an alternative medical cause. A high follicle stimulating 
hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in 
women not using hormonal contraception or hormonal replacement therapy. However, in the absence of 
12 months of amenorrhea, a single FSH measurement is insufficient.   
Effective methods of contraception are listed below:

Liver Histology and Event Adjudication and Data Monitoring Committee Oversight: 
Central Reading of Liver Histology:  All biopsy assessments will be performed centrally, including assessments 
of biopsies to determine study eligibility.  Histological presence of NASH with a fibrosis score of 4 based on the 
NASH CRN scoring system must be confirmed for study eligibility.  For each biopsy, fibrosis will be graded in 
accordance with the NASH CRN scoring system (Kleiner 2005).   
Biopsy samples will be assessed for quantitative collagen in a subset of subjects as an exploratory objective. 
Any extra biopsy tissue may undergo additional histological evaluations such as alpha-smooth muscle actin or 
bile acid transporter analysis. 
Event Adjudication:  Potential liver-related clinical outcomes, and potential events of hepatic injury, AKI, and 
major adverse cardiovascular events (MACE), deaths, and hospitalizations (depending on the cause) that occur 
after administration of the first dose of investigational product will be reviewed by the following blinded 
adjudication committees, depending on event type, before inclusion in any analysis.  The 4 committees that are 
responsible for adjudicating events are as follows: 
• 
Cardiovascular Adjudication Committee:  Adjudicates all potential MACE (including all deaths) and 
hospitalizations (depending on the cause) 
• 
Hepatic Outcomes Committee:  Adjudicates all deaths and potential liver-related clinical outcomes  
• 
Hepatic Safety Adjudication Committee (HSAC):  Adjudicates all potential events of hepatic injury  
• 
Renal Adjudication Committee:  Adjudicates all potential events of AKI 
The adjudication committee members will include experts with relevant adjudication experience; they will not be 
involved in the study as Investigators, Data Monitoring Committee (DMC) members, or consultants.   
Specific details of the events that will be adjudicated by the Cardiovascular Adjudication Committee, Hepatic 
Outcomes Committee, HSAC, and Renal Adjudication Committee are described in the respective adjudication

or tolerability reasons.  Treatment assignment will be based on the randomized treatment. 
Per Protocol (PP) Population: 
The PP Population will include all mITT subjects who do not have any major protocol violations that potentially 
affect the efficacy conclusions.  Treatment assignment will be based on the randomized treatment. 
Safety Population: 
The Safety Population will include all randomized subjects who receive at least 1 dose of investigational product 
(OCA or placebo).  The Safety Population will be the primary population used for safety analyses.  Treatment 
assignment will be based on the treatment actually received. 
Efficacy Analyses 
For the comparison of the primary efficacy endpoint, a Cochran Mantel Haenszel (CMH) test stratified by the 
randomization strata (presence of type 2 diabetes at enrollment [yes/no] will be used.  The overall type I error 
will be controlled at 0.05 for the primary analysis 
Primary efficacy hypothesis testing will be based on the ITT population.  Supportive analyses of the primary 
endpoint will be conducted using the mITT and PP population. 
The primary efficacy analysis will test the following hypotheses:

compared to placebo, as listed under the secondary objectives.  Only adjudicated events will be included in 
analyses.  Subjects with none of these events will be censored at the date of last contact.  For the analysis of time 
to first occurrence of adjudicated events, in addition to the CMH test statistics, a log rank test stratified by the 
randomization stratification factor (presence of type 2 diabetes at enrollment [yes/no]) will be used.  Kaplan-
Meier estimates of the distribution of the time-to-event will be tabulated and graphed by treatment group. 
 
Safety Analyses 
Safety evaluations will comprise treatment-emergent AEs, AEs of special interest (including cardiovascular, 
pruritus, renal, urinary tract stones including nephrolithiasis, gallbladder/gallstone-related, pancreatitis, hepatic, 
dyslipidemia, and hyperglycemia/new-onset diabetes mellitus AEs), adjudicated hepatic safety events,

Confidential and Proprietary 
Safety evaluations conducted during the Double-Blind Phase will also be conducted for the OLE.  For 
quantitative parameters including, but not limited to, vital signs, ECG, and clinical laboratory results, changes 
from double-blind baseline value and OLE baseline value will be presented.  Analyses based on the double-blind 
baseline will be performed using the treatment actually received in the Double-Blind Phase.  Analyses based on 
the OLE baseline will be based on the treatment actually received in the OLE Phase. 
Efficacy Analyses (OLE) 
The occurrence of all-cause mortality and liver-related clinical outcomes will be summarized.  For additional 
exploratory analyses, please refer to SAP for more details. 
Sample Size Justification 
A sample size of 300 subjects per group will provide at least 90% power to detect a statistically significant 
treatment difference of 10% between OCA 25 mg and placebo groups based on a Chi-square test with 2-sided 
type I error at 0.05 level, assuming a responder rate of 10% in the placebo group.  As there was no previous study 
performed using the same endpoint in this disease, the assumption was determined based on data from literature, 
and results from the Farnesoid X receptor Ligand OCA in Nonalcoholic Steatohepatitis Treatment (FLINT) study 
and Study 747-303.

INTRODUCTION 
5.1. 
Overview of Nonalcoholic Steatohepatitis and Obeticholic Acid 
Nonalcoholic fatty liver disease (NAFLD) is considered to be a hepatic manifestation of 
metabolic syndrome, a cluster of closely related clinical features linked to visceral obesity and 
characterized by insulin resistance, dyslipidemia, and hypertension.  NAFLD is the most common 
cause of chronic liver disease in the western hemisphere.  As the prevalence of obesity and 
metabolic syndrome rises in the industrial world, NAFLD is expected to rise in parallel.  NAFLD 
is thought to be represented by a spectrum of histologically-defined diseases, which progresses 
from simple steatosis to nonalcoholic steatohepatitis (NASH).  Up to one-third of NAFLD 
patients go on to develop NASH, which is characterized by hepatocellular injury, inflammation, 
and progressive fibrosis potentially leading to cirrhosis.  As opposed to simple steatosis, NASH is 
associated with significant morbidity and progression that, if left untreated, can progress to 
advanced fibrosis, cirrhosis, hepatic decompensation, hepatocellular carcinoma (HCC), and liver-
related death (Vernon 2011).  Of all the histologic features of NASH, fibrosis is considered the 
strongest predictor of adverse clinical outcomes, including liver-related death (Younossi 2011, 
Ekstedt 2015). 
Despite the seriousness of the disease, especially when advanced fibrosis/cirrhosis is present, 
there are currently no approved pharmacologic treatments.  The current treatment strategy for 
NASH patients with cirrhosis becomes largely supportive, focused primarily on managing 
complications and, as a last resort, liver transplant.  It is therefore critical to develop effective 
therapies that can reverse fibrosis or prevent the progression of fibrosis to cirrhosis, with the goal 
of reducing complications secondary to cirrhosis ultimately improving quality of life and 
liver-transplant-free survival. 
In view of the serious nature of the disease, the increasing prevalence, the complications that arise 
from the disease, and the unmet medical need, approved therapy for NASH is warranted.  
Obeticholic acid (OCA) is a modified bile acid and farnesoid X receptor (FXR) agonist that is 
derived from the primary bile acid chenodeoxycholic acid (CDCA), the natural human FXR 
ligand. 
OCA’s potent FXR agonist effects make it an attractive novel therapeutic agent for NASH due to 
its multiple FXR-mediated effects, including prevention and reversal of liver fibrosis, 
anti-inflammatory effects in liver and vasculature, and hepatocyte protection against bile 
acid-induced cytotoxicity.  Specifically, nonclinical studies have shown several potentially 
beneficial properties of FXR agonism in NASH and cirrhosis (Adorini 2012, Mudaliar 2013).   
5.2. 
Nonclinical Experience with OCA 
Non-clinical studies clarifying the anti-inflammatory, anti-fibrotic and anti-cirrhotic mechanisms 
underlying OCA’s effect in NASH include the following: 
• In mice, OCA has been shown to alleviate key histologic hallmarks of NASH in 
high-fat/high-cholesterol diet-induced and biopsy-confirmed disease as reflected by 
improvements in nonalcoholic fatty liver disease activity score (NAS), steatosis, 
ballooning and immunohistochemical markers of fibrosis (eg, collagen 1a1 [Col1a1]) 

Protocol 747-304 
Version 7.0:  16Jun2021

Confidential and Proprietary 
and inflammation (eg, galectin 3; Roth 2017).  These effects were associated with 
regulation of FXR target genes within the gut-liver axis and improvements in genes 
involved in monocyte recruitment and fibrosis (eg, monocyte chemoattractant protein-
1 [MCP-1], Col1a1, collagen type III alpha 1 chain, membrane palmitoylated protein 
2, tissue inhibitor of metalloproteinase 2).  These findings further confirm the benefits 
of FXR agonism by OCA in a rodent model of NASH. 
• Hepatic fibrosis ultimately progresses to cirrhosis.  While it is difficult to induce 
cirrhosis by simple high fat feeding, this stage can be readily induced in rodents by the 
application of thioacetamide (TAA).  Importantly, therapeutic effects have been 
demonstrated when OCA was administered concurrently or following established 
cirrhosis within the rat TAA model (Verbeke 2016).  These benefits were associated 
with: (1) functional hepatic improvements such as a reduction in portal pressure 
through reduced intrahepatic vascular resistance, and (2) a decreased expression of 
pro-fibrotic cytokines (transforming growth factor β, connective tissue growth factor, 
and platelet derived growth factor) and markers of hepatic cell turn-over by blunting 
effects of pro-inflammatory cytokines (MCP-1). 
• To dissect out the contribution of individual cell types, in vitro studies interrogated the 
potential for direct effects of OCA upon isolated hepatic stellate cells (HSCs), Kupffer 
cells, hepatocytes, and liver sinusoidal endothelial cells.  Collectively, these findings 
suggest that the improvements manifest via indirect effects on immune activation and 
hepatic cell turn-over and are linked to a decrease in nuclear factor 
kappa-light-chain-enhancer of activated B cell activation and cytokines promoting 
fibrosis and inflammation within the liver parenchyma (Verbeke 2016).  These effects 
do not appear to be due to a direct effect upon HSCs (Fickert 2009, Verbeke 2016). 
• Although not formally addressed in a cirrhotic model, interactions between the 
intestinal mucosal barrier and liver (the “gut-liver axis”) are recognized as important 
contributors to the clinical pathogenesis of NASH (van Best 2015).  Under healthy 
conditions, the intestinal mucosal barrier is the first line of defense against antigens 
and inflammatory mediators escaping from gut mucosal immune surveillance.  
Disruption results in bacterial translocation to the extra-intestinal space, activating the 
immune system and triggering further hepatic inflammation and damage.  In animal 
models (Garcia-Tsao 1995) and human cirrhosis, bacterial translocation is a prelude to 
hepatic decompensation, further liver impairment, and, ultimately, organ failure.  In 
preclinical models, these effects are attenuated following OCA administration.  
For example, OCA inhibits gastrointestinal inflammation and preserves intestinal 
barrier function in models of inflammatory bowel diseases, upregulating expression of 
anti-bacterial genes and inhibiting bacterial translocation (Gadaleta 2011).  In the bile 
duct ligation model, OCA treatment improves ileal barrier function by attenuating 
intestinal inflammation and reducing bacterial translocation, a key driver in the 
pathogenesis and complications of liver cirrhosis (Verbeke 2015). 
In summary, there is strong rationale to advance OCA for the treatment of NASH based on its 
FXR-mediated hepatoprotective properties.

Clinical Experience with Obeticholic Acid 
OCA (Ocaliva) has received marketing authorization in the United States, Europe, Canada, and 
several other countries for the treatment of primary biliary cholangitis (PBC) in combination with 
ursodeoxycholic acid (UDCA) in adults with an inadequate response to UDCA, or as 
monotherapy in adults unable to tolerate UDCA.  OCA is currently being developed for the 
treatment of multiple chronic nonviral liver diseases, including NASH with fibrosis, NASH with 
cirrhosis, primary sclerosing cholangitis, and biliary atresia. 
The clinical development program for OCA in subjects with NAFLD or NASH includes data 
from the following 6 completed studies: 
• Study 747-203:  A proof-of-concept, Phase 2 study in subjects with type 2 diabetes 
and presumed NAFLD to evaluate the effects of OCA on insulin sensitivity 
(Mudaliar 2013). 
• FXR Ligand OCA in NASH Treatment (FLINT):  A Phase 2 study conducted by the 
National Institute of Diabetes and Digestive and Kidney Diseases and the NASH 
Clinical Research Network (CRN) to evaluate the efficacy and safety of OCA in the 
treatment of NASH (Neuschwander-Tetri 2015). 
• Study D8602001:  A Phase 2 study conducted by Intercept’s Asian development 
partner (Sumitomo Dainippon Pharma Co., Ltd) to evaluate the efficacy and safety of 
3 doses of OCA versus placebo in NASH. 
• Study 747-209:  A Phase 2, double-blind, randomized, placebo-controlled, multicenter 
study evaluating the effect of OCA, and the subsequent addition of statin therapy, on 
lipoprotein metabolism in subjects with NASH with fibrosis stage 1 to 4, but no 
evidence of hepatic decompensation. 
• Study 747-117:  A Phase 1, double-blind, randomized, placebo-controlled study 
evaluating the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of OCA in 
subjects with NASH fibrosis. 
• Study 747-118:  A Phase 1, single-center, double-blind, randomized study evaluating 
the safety, pharmacokinetics, and pharmacodynamics of OCA in healthy subjects and 
subjects with compensated Child-Pugh (CP) Class A cirrhosis due to NASH. 
− Including a 747-118 hepatic PK substudy in subjects with cirrhosis due to NASH. 
Study 747-203 showed improved insulin sensitivity in subjects with type 2 diabetes and NAFLD, 
demonstrating the clinical relevance of the FXR agonist pathway and supporting the potential of 
OCA to treat NAFLD and/or NASH.  With the exception of weight loss, OCA 25 mg appeared to 
be at least as effective as OCA 50 mg for the majority of endpoints evaluated.  Pruritus (including 
generalized pruritus) in Study 747-203 occurred at a comparable incidence in OCA-treated and 
placebo-treated subjects with NAFLD; the incidence was approximately 9% to 10% between 
placebo and the highest OCA dose (50 mg).  No subject from Study 747-203 withdrew from the 
study due to pruritus. 
The FLINT study demonstrated that OCA 25 mg was superior to placebo in improving not only 
the key histologic features important in the underlying pathophysiology of the disease

(inflammation, ballooning, and steatosis), but notably also fibrosis (35% OCA versus 19% 
placebo; p = 0.004).  Across all fibrosis change categories (fibrosis improvement of ≥1 stage of 
fibrosis, ≥2 stages of fibrosis or resolution of fibrosis), a greater percentage of OCA-treated 
subjects were responders compared to placebo.  Importantly, a significantly greater percentage of 
subjects in the OCA group (17%) showed fibrosis resolution after 72 weeks of treatment 
compared to placebo (5%).  In addition, although the numbers were small (likely due to the 
limited 72-week treatment period), fewer OCA-treated subjects (2%) progressed to cirrhosis 
compared to placebo (5%).  OCA treatment was also associated with improvement in markers of 
hepatocellular injury and some cardiometabolic features, including weight and systolic blood 
pressure.   
Low-density lipoprotein cholesterol (LDLc) demonstrated a modest but significant increase in 
subjects treated with OCA compared to placebo; however, this increase was reversed and LDLc 
cholesterol returned to below baseline levels in subjects who initiated statin therapy.  The general 
adverse event (AE) profile was similar between the OCA 25 mg and placebo groups, with the 
exception of pruritus.  Pruritus occurred more frequently in the OCA-treated subjects (23% OCA 
versus 6% placebo), led to 1 discontinuation, and was generally mild and moderate in severity.  
Otherwise, pruritus was well managed with the use of antipruritic medications and treatment 
interruption. 
Study D8602001 demonstrated a dose-dependent increase in the percentage of OCA-treated 
subjects compared to placebo subjects who achieved the primary endpoint (p = 0.053, not 
significant).  The 40-mg OCA dose group achieved statistical significance for the primary 
endpoint compared to placebo (p = 0.0496).  Dose-dependent trends not reaching statistical 
significance were also observed for several other pre-specified histologic endpoints, including the 
proportion of subjects with steatosis and inflammation improvement, ballooning resolution, and 
NASH resolution.  In the completer analysis, similar dose-dependent effects were observed, with 
51% of patients in the 40-mg dose group compared to 22% in the placebo group meeting the 
primary endpoint (p = 0.0061).  With the exception of dose-dependent pruritus, OCA appeared to 
be generally safe and well tolerated.  The number of pruritus-associated treatment 
discontinuations were 0, 0, 2, and 5 subjects in the placebo, 10-mg, 20-mg, and 40-mg OCA 
groups, respectively.  Changes in lipid parameters were directionally similar to those observed in 
NASH subjects in the FLINT study.  No other meaningful differences in the rate of AEs between 
the OCA and placebo groups were noted. 
Study 747-209 further evaluated the effect of OCA and atorvastatin treatment on LDLc 
metabolism in subjects with NASH and liver fibrosis to better characterize the lipid profile 
changes observed in the FLINT study, as well as their management.  Subjects with 
biopsy-confirmed NASH and fibrosis received placebo or OCA 5 mg, 10 mg, or 25 mg once 
daily, for up to 4 weeks.  Subjects then initiated concurrent treatment with atorvastatin 10 mg 
once daily, and titrated to 20 mg once daily at Week 8 based on tolerability.  At Week 4, prior to 
initiation of statin treatment, subjects experienced an approximately 20% to 25% increase in 
LDLc concentrations across all OCA groups.  By Week 8, atorvastatin treatment effectively 
lowered LDLc to below baseline levels across all treatment groups.  Together, these study results 
suggest that the risk of increases in LDLc with OCA use can generally be managed by statin use.  
Pruritus was the most common AE and was dose dependent.  Two subjects discontinued the study 
due to pruritus.

Study 117 demonstrated that the PK profile of OCA in subjects with NASH fibrosis was 
consistent with what has been observed in healthy subjects and largely reflective of enterohepatic 
recirculation with exposure proportional to dose.  Treatment with OCA 10 mg or 25 mg once 
daily for 12 weeks was found to be safe and well tolerated in NASH subjects with fibrosis 
(including fibrosis stage 1 through stage 4).  The PD assessments demonstrated FXR activation 
and positive trends for select markers of fibrosis, inflammation, apoptosis, and liver function.   
Study 747-118 demonstrated that the safety profile of 10 mg and 25 mg doses of OCA in subjects 
with compensated CP Class A cirrhosis due to NASH was similar to the safety observed in 
healthy subjects, supporting their use in longer term efficacy studies.  The hepatic PK substudy 
demonstrated that OCA 25 mg was safe and generally well tolerated, showing improvements in 
the levels of liver biochemistry markers associated with hepatocellular injury when administered 
for 28 days to subjects with CP Class A cirrhosis due to NASH, consistent with results from the 
double blind period. 
The following studies evaluating OCA for the treatment of NASH are currently ongoing: 
• The clinical outcome portion of Study 747-303.

Rationale for Study Design and Dose for Investigational Product 
5.4.1. 
Rationale for Study Design 
NASH is a serious, chronic liver disease with a large unmet medical need and no approved 
therapies.  Patients with cirrhosis in the spectrum of NASH disease continuum represent the 
highest unmet medical need and are at the greatest risk of disease progression.  NASH has 
become one of the leading causes of liver transplant (Wong 2020, Younossi 2020), highlighting 
the need for development of effective therapies that may improve steatohepatitis and fibrosis, 
potentially delaying liver transplant or death.  As fibrosis has been consistently shown to be the 
strongest predictor of adverse clinical outcomes, including liver-related death, it is critical to 
prevent further progression of fibrosis and preferably reverse fibrosis.  Results from FLINT and 
the 18-month interim analysis of Study 747-303 have demonstrated that OCA has robust anti-
fibrotic effects and improves underlying disease activity and steatohepatitis in NASH subjects 
with fibrosis at the 18-month assessment.  Study 747-304 will evaluate efficacy (based on 
histological improvement in fibrosis) and safety of OCA in NASH subjects with compensated 
cirrhosis (defined by a NASH Clinical Research Network [CRN] score of 4), and CP score <7. 
5.4.2. 
Rationale for Placebo Control Group  
The use of a randomized placebo control group added to established standard of care, including 
lifestyle modification counseling, provides the best scientific evidence of efficacy and safety.  The 
use of a placebo control provides a concurrent comparator group, accounting for not only a 
placebo effect but a standard of care effect.  As there is no approved or proven pharmacologic 
therapy for NASH, using a placebo for comparative purposes is justified.

5.4.3. 
Rationale for Obeticholic Acid Doses and Duration 
In addition to placebo, two dosing regimens of OCA will be evaluated in this study: (1) Titration 
regimen (OCA 10 mg → 25 mg) in which OCA will be initiated at a dose of 10 mg once daily 
followed by uptitration to 25 mg once daily at Month 3; and (2) OCA 10 mg once daily for the 
entire duration of the study. 
This dose titration was selected based upon the known mechanism of FXR and on clinical 
experience in completed Phase 2 studies in subjects with NAFLD (747-203) and NASH (FLINT), 
as well as a clinical pharmacology study in subjects with hepatic impairment (Study 747-103). 
FXR is a nuclear receptor that senses bile acids and regulates their intracellular levels in 
hepatocytes.  FXR activation leads to the reduction of intracellular bile acid levels by increasing 
the export of bile acids from cells, thereby decreasing bile acid uptake and bile acid synthesis.  
After 12 weeks of dosing OCA, FXR activation has been shown to reduce systemic bile acid 
levels while maintaining relatively low OCA levels in the total bile acid pool (<2%). 
Study 747-203, a 6-week study that evaluated the efficacy and safety of OCA 25 mg, 
OCA 50 mg, and placebo in 64 subjects with type 2 diabetes mellitus and NAFLD, demonstrated 
that both OCA 25 mg and 50 mg doses were similarly efficacious in improving insulin sensitivity 
as well as markers of fibrosis such as Enhanced Liver Fibrosis (ELF).   
The efficacy and safety of OCA 25 mg was also evaluated in the FLINT study in which patients 
with NASH fibrosis were treated for a period of 72 weeks.  In this study, OCA-treated patients 
showed significant improvements in histologic parameters, including improvements in features of 
steatohepatitis, improvement of fibrosis, and resolution of NASH.  In both studies, OCA 25 mg 
was well tolerated with pruritus being the most common treatment-emergent adverse event 
(TEAE) in FLINT (23% OCA vs 6% placebo).  In summary, the OCA 25 mg dose has 
demonstrated significant histologic improvement in patients with NASH fibrosis while being well 
tolerated, and has therefore been selected for further evaluation in the population with cirrhosis 
who has not reached CP score ≥7.  
The dedicated hepatic impairment study (747-103) using OCA 10 mg has shown only 10% 
increase in the systemic concentrations of total OCA in subjects with CP Class A compared to 
that of healthy subjects.   
Therefore, the dose of OCA 10 mg will be administered for 3 months to support the lowering of 
bile acid levels in CP Class A subjects.  After 3 months, titration of OCA 25 mg administration is 
introduced to provide clinically proven beneficial doses.  Study 747-209 evaluated a range of 
doses from 5 mg to 25 mg in subjects with NASH and fibrosis, including subjects with 
compensated cirrhosis.  In this study, treatment of NASH subjects with compensated cirrhosis 
with up to 25 mg OCA was found to be safe and well tolerated, and the AE profile of cirrhotic 
subjects was not different from that of precirrhotic subjects.  Guidelines for subjects who progress 
beyond CP Class A are provided in Section 7.4. 
In addition to the titration dosing regimen, an arm evaluating OCA 10 mg once daily will also be 
evaluated.  While OCA 25 mg once daily was well-tolerated overall, there was an increased 
incidence of mostly mild or moderate pruritus in OCA-treated subjects compared to 
placebo-treated subjects in the FLINT and 747-209 studies.  Pruritus was also the most common 
AE associated with OCA in PBC studies, and has been shown to be dose related, warranting 

Protocol 747-304 
Version 7.0:  16Jun2021 
Page 37 
 
Confidential and Proprietary 
evaluation of lower doses as a potential strategy to improve tolerability.  Phase 2 and Phase 3 
studies evaluating OCA for the treatment of PBC have shown that the incidence and severity of 
pruritus with OCA treatment can be mitigated with lower OCA doses.  Therefore, based on the 
therapeutic effect of 10 mg in PBC and to evaluate potential attenuation of effect of OCA on 
pruritus and serum lipid levels, a lower dose of 10 mg daily will be evaluated in this study in 
addition to the titration dosing regimen. 
Rationale for Treatment Duration of 18 Months 
The natural history of NASH with liver fibrosis shows that both progression and regression of 
liver fibrosis are slow processes that may take years to develop as well as to improve.  A 
systematic review and meta-analysis of paired-biopsy studies has shown that a 1-stage change in 
fibrosis occurs over a median of 7.1 years in patients with NASH (Singh 2015).  Regression of 
fibrosis in established NASH cirrhosis is expected to take even longer (Cheung 2019).  To date, 
no clinical trial in subjects with NASH cirrhosis has demonstrated efficacy with respect to 
reversal of cirrhosis and there are no approved treatment options for NASH cirrhosis. 
As presented above, OCA has shown robust anti-fibrotic effects based on histologic endpoints in 
pre-cirrhotic NASH subjects with liver fibrosis.  A treatment duration of 12 months was initially 
selected for the placebo-controlled portion of this study based on non-histological data (using 
serum biomarkers of fibrosis observed in Study 747-203 and FLINT).  However, the effects of 
OCA on liver histology at earlier time points, including 12 months, had not been assessed.  The 
preliminary results of the 18-month interim analysis from Study 747-303 showed that OCA 
25 mg was superior to placebo, demonstrating histological improvement of NASH fibrosis 
without worsening of NASH with an effect size of ~11% over 18 months of treatment 
(Younossi 2019).  However, the results also highlighted the slow process of regression of liver 
fibrosis and the potential challenges of demonstrating efficacy in regression of liver fibrosis 
within a finite time period.  Based on the above considerations, the duration of treatment in the 
Double-Blind Phase has been extended to 18 months. 
5.5. 
Summary of Known Potential Risks with Investigational Product 
The rate of progression and risk of hepatic decompensation is variable and may be rapid in certain 
patients, necessitating closer surveillance of patients at risk.  Investigators should inform 
participating subjects of known and anticipated risks associated with OCA treatment and prompt 
them to communicate with the Investigators in the event of any adverse experiences. 
Post-Marketing Cases of Liver Injury in PBC 
In post-marketing reports, hepatic decompensation and failure, in some cases fatal, have been 
reported in PBC subjects with decompensated cirrhosis or Child-Pugh Class B or C hepatic 
impairment when OCA was dosed more frequently than the recommended starting dosage of 
5 mg once weekly (ie, off-label use).  Subjects who died due to hepatic complications generally 
had decompensated cirrhosis prior to treatment and were started on OCA 5 mg QD, which is 
7-fold greater than the once weekly starting regimen in this population and considered to be a 
medication error. 
Based on a comprehensive review in 2017 of both existing and new clinical information, 
including more than 1300 patient-years of exposure and subjects with advanced disease, multiple 
analyses confirm lack of hepatotoxicity at the current recommended doses of OCA.  The existing 

Protocol 747-304 
Version 7.0:  16Jun2021 
Page 38 
 
Confidential and Proprietary 
post-marketing evidence at that time was considered insufficient to confirm a causal relationship 
between exposure to OCA and the occurrence of hepatic decompensation and/or death.  The 
majority of cases reported were for advanced PBC patients receiving doses inconsistent with 
dosing instructions in the label.  Even in these cases, there is no clear evidence that the higher 
than recommended dosing frequency of OCA led to adverse outcomes.  
PBC is a chronic progressive liver disease, ultimately progressing to hepatic fibrosis and eventual 
cirrhosis, hepatic decompensation, liver transplant, and/or death.  Given that hepatic 
decompensation events are part of the natural history of PBC and patients with end stage disease 
are particularly vulnerable, it is often not possible to distinguish on a case level the hypothesized 
drug effects from the natural history of the disease. 
As a result, a boxed warning was added to the labeling in 2018 providing additional guidance on 
patient management for patients with decompensated cirrhosis as well as stronger dosing 
guidelines.   
A new label, approved on 01 June 2021, states that in the US, OCA is now contraindicated in 
PBC subjects with compensated cirrhosis with evidence of portal hypertension after a Newly 
Identified Safety Signal evaluation. 
Clinical Study Experience 
Liver-related events 
Systemic and hepatic concentrations of OCA increase significantly in patients with moderate to 
severe hepatic impairment.  In PBC clinical studies, a dose-response relationship was observed 
for the occurrence of liver-related adverse reactions with OCA, including jaundice, worsening 
ascites, and PBC flare with dosages of OCA 10 mg to 50 mg once daily.  Most events occurred at 
a dose up to 5-fold higher (50 mg) than the maximum recommended marketed dose (10 mg).  
Clinically relevant increases in AST, ALT, or conjugated bilirubin (markers of liver injury) were 
rarely seen at the intended clinical doses of 5 mg or 10 mg.  Elevated liver enzymes were 
observed in healthy subjects who were treated at doses ≥100 mg in Phase 1, multiple-dose 
studies; however, these elevations were only considered to be of clinical concern at the maximum 
dose of 250 mg daily.  Cases of hepatic decompensation cases have also occurred in PBC.  The 
majority of the cases were considered not related or unlikely related to investigational product by 
the Investigator.  In general, subjects who experienced hepatic decompensation either entered the 
study with more advanced disease, or for those studies where subjects started earlier in disease 
progression, events of hepatic decompensation generally occurred at least 1 year after the 
initiation of treatment or on higher doses. 
In a pooled analysis of 3 completed placebo-controlled clinical trials in subjects with primarily 
early-stage PBC, the exposure-adjusted incidence rates for all serious and otherwise clinically 
significant hepatic adverse reactions and isolated elevations in liver biochemical tests per 
100 patient exposure years were 5.2 in the OCA 10 mg group (highest recommended dosage), 
19.8 in the OCA 25 mg group (2.5 times the highest recommended dosage), and 54.5 in the OCA 
50 mg group (5 times the highest recommended dosage) compared to 2.4 in the placebo group. 
Analyses of liver-related safety information from NASH subjects treated with OCA demonstrate 
an overall hepatic safety profile consistent with PBC.  There is no evidence to indicate a 
consistent, dose-dependent worsening of liver biochemistries at doses up to 25 mg, including 

Protocol 747-304 
Version 7.0:  16Jun2021 
Page 39 
 
Confidential and Proprietary 
ALT, AST or bilirubin.  Modest increases in alkaline phosphatase (ALP) levels have occurred 
following treatment with OCA; however, ALP levels were generally within upper limits of 
normal.  ALP elevations are generally not associated with a rise in gamma-glutamyl transferase 
(GGT), suggesting that these changes are unlikely to be due to cholestatic liver injury. 
In NASH clinical trials 9 cases of hepatic decompensation have been reported as SUSARs, 1 of 
which resulted in death.  The signs of hepatic decompensation included death due to a hepatic 
event; MELD score ≥15; liver transplant; ascites; or a serious adverse event (SAE) of variceal 
bleed, hepatic encephalopathy, or spontaneous bacterial peritonitis.   
Of these events, one was considered unlikely related to OCA and 6 were considered possibly 
related to blinded treatment.  The remaining events were considered possibly related to treatment 
and concerned subjects receiving daily OCA 40 mg.  One case describes a subject with an event 
of DILI, and a second case describes a subject with events of ascites and pruritus.  In the case 
with ascites and pruritus, treatment was discontinued.  Both subjects recovered from the events.  
Key hepatic findings in NASH subjects include the following:   
• In completed NASH clinical studies, cumulative on-study incidence rates for hepatic 
AEs and corresponding hazard ratios indicate that the rates of hepatic SAEs are not 
different across OCA and placebo groups.  Although more events occurred in the OCA 
25 mg group (6 [1%] subjects) than in the OCA 10 mg group (2 [<1%] subjects) or 
placebo group (2 [<1%] subjects), expert reviewers did not identify sufficient evidence 
supporting a consistent pattern of liver injury, and notably, the vast majority of cases 
were associated with confounding concomitant medications or severe intercurrent 
illness.   
• Given that the liver is the primary site of action for OCA safety and efficacy, liver 
concentrations for total OCA were predicted for subjects with hepatic impairment 
based on Child-Pugh Class score.  A 1.1-fold increase in liver OCA exposure is 
predicted in subjects with mild hepatic impairment (Child-Pugh Class A); however, a 
1.5- and 1.7-fold increase in liver concentrations of OCA are predicted for Child Pugh 
Class B and C respectively, when compared to that of healthy subjects (Edwards 
2016).  In a hepatic impairment study (747-118) in NASH subjects with compensated 
liver cirrhosis (Child-Pugh Class A), plasma exposure was approximately 4- to 10-fold 
higher, and liver exposure was approximately 2-fold higher as compared to NASH 
subjects with liver fibrosis.  OCA has not been evaluated in NASH subjects with 
decompensated cirrhosis (Child-Pugh Class B and Child-Pugh Class C). 
Pruritus 
Pruritus is an expected adverse event associated with OCA, particularly in subjects with 
cholestatic liver diseases such as PBC where pruritus is a common symptom of the disease.  In 
PBC clinical studies, the incidence of pruritus was 68% for OCA-treated subjects compared with 
40% in placebo-treated subjects.  The majority of events have been reported as mild to moderate 
in severity and infrequently resulted in early discontinuation.  The majority of subject’s 
experiencing pruritus did not require an intervention for pruritus.  The incidence and severity of 
pruritus have been shown to be dose dependent, but there is no evidence of association with stage 
or progression of underlying disease.   

Protocol 747-304 
Version 7.0:  16Jun2021 
Page 40 
 
Confidential and Proprietary 
Pruritus has also been observed in subjects with NASH.  Across the three, long-term, 
double-blind, placebo-controlled studies in subjects with liver fibrosis due to NASH (747-303, 
FLINT, and D8602001), the incidence of pruritus TEAEs was dose dependent and higher in the 
OCA 25 mg group, as compared to the OCA 10 mg and placebo groups.  The majority of pruritus 
TEAEs were mild to moderate in severity.  The incidence of severe pruritus TEAEs was low, but 
higher in the OCA 25 mg group, as compared to the OCA 10 mg and placebo groups.  The 
incidence of new or worsening pruritus TEAEs was highest early in the course of treatment (ie, 
first 3 months) and subsequently decreased over time.  Consistent with the PBC experience, 
pruritus in subjects with NASH appeared to be manageable with temporary interruption of OCA 
treatment and the use of antipruritic medications.  
Lipids 
In subjects with NASH (FLINT), compared to placebo, treatment with OCA was associated with 
statistically significant elevations in the mean total serum cholesterol and LDLc levels, and a 
decrease in the mean HDL, which remained within normal limits.  These changes developed 
within the first 12-week time point after beginning of treatment, decreased over time after Week 
12, and returned to baseline levels when OCA treatment was withdrawn. 
Withdrawal of OCA treatment reversed the OCA-induced LDLc increase in all groups, including 
subjects who were not on statins (Neuschwander-Tetri 2015).  In Study 747-209, subjects with 
NASH and dyslipidemia received placebo or OCA 5mg, 10 mg, and 25 mg once daily, for up to 
4 weeks.  Subjects then initiated concurrent treatment with 10 mg atorvastatin once daily titrated 
to 20 mg once daily based on tolerability.  At Week 4, subjects experienced approximately 20% 
to 25% increases in LDLc particles across all OCA groups.  By Week 8, atorvastatin treatment 
effectively lowered LDLc to below baseline levels across all OCA groups compared to patients 
not on a statin. 
Together, the small magnitude of OCA mediated cholesterol and LDL changes, coupled with their 
reversibility upon cessation of OCA treatment and/or responsiveness to statin-initiation, suggest 
that this risk can be managed by statins as needed. 
Glycemic Changes 
In NASH clinical studies, treatment with OCA was associated with a generally modest and 
transient rise in glycemic parameters (fasting plasma glucose, fasting serum insulin, and 
hemoglobin A1c (HbA1c), a well-established marker of long-term glycemic control) that 
occurred early (ie, within the first 3 months) and attenuated, returning to levels similar to placebo 
after approximately 6 months of treatment. 
5.5.1. 
Risk/Benefit Profile of OCA in Subjects with NASH 
An independent data monitoring committee (DMC) has performed detailed reviews of individual 
subject and aggregate data from both the Phase 3 clinical outcomes study in subjects with PBC 
(Study 747-302) and the Phase 3 pivotal studies in subjects with NASH fibrosis (Study 747-303) 
and NASH cirrhosis (Study 747-304) on a quarterly basis, in an unblinded fashion, and in closed 
sessions (without the Sponsor’s participation).   
Following a request from the FDA, an ad hoc DMC review was held, and the DMC recommended 
that: 

Protocol 747-304 
Version 7.0:  16Jun2021 
Page 41 
 
Confidential and Proprietary 
• For subjects in Study 747-303, investigational product should be interrupted in 
subjects who experience symptomatic cholelithiasis and/or cholecystitis. 
In a subsequent DMC review, the DMC recommended that: 
• For subjects in Study 747-303, investigational product should be permanently 
discontinued in subjects diagnosed with acute pancreatitis. 
The Sponsor decided to implement the DMC recommendations across the NASH program. 
In summary, based on the robust efficacy of OCA observed in PBC and NASH clinical studies, 
including improvements in liver biochemistry, fibrosis, and key histological features of NASH, as 
well as the overall safety profile of OCA (in >2300 healthy subjects and subjects with chronic 
liver diseases), the benefit-risk profile is favorable. 
Refer to the Investigator’s Brochure for additional information regarding the known potential 
risks with the investigational product. 
5.6. 
Importance of Monitoring of Disease Progression 
NASH is a chronic, progressive liver disease with variable rates of progression to cirrhosis and 
hepatic decompensation, although both may occur rapidly in certain patients.  Subjects with 
NASH cirrhosis have accentuated risks relative to subjects with non-cirrhotic NASH and can 
transition abruptly from a clinically compensated state to decompensated cirrhosis, with the 
manifestations of portal hypertension and impaired synthetic function that characterize end-stage 
liver disease.  Subjects with NASH cirrhosis must, therefore, be closely monitored to ensure early 
identification of signs and symptoms of decompensation and/or liver injury.  In this study, close 
and thorough safety monitoring is paired with appropriate investigational product dosing 
adjustment, interruption, and discontinuation to ensure subject safety. 
Investigators, together with the Sponsor’s Medical Monitor or designee, will consistently and 
frequently assess individual subjects, including careful evaluation of signs, symptoms, and 
laboratory parameters to identify potential hepatic injury and/or decompensation.  Criteria for 
potential hepatic injury and/or progression to decompensation are described in Section 7.4.  
Criteria for implementing dosing adjustments, interruptions, or discontinuations, and close 
monitoring procedures are described in Section 7.4.4 and Section 7.7. 
For subjects randomized to the uptitration arm, special consideration is given to monitoring and 
management of investigational product as discussed in more detail in Section 9.2.  Uptitration 
criteria have been designed to ensure that only subjects with evidence of adequate functional 
hepatic reserve will be exposed to the higher OCA dose (25 mg).  Specifically, subjects may only 
be uptitrated at Month 3 if, in addition to no safety or tolerability concerns being identified, they 
meet strict laboratory criteria (total bilirubin ≤1.2 mg/dL, serum albumin ≥3.5 g/dL, INR <1.5, 
and platelet count >100,000/mm3) at both baseline and all visits prior to Month 3.  Furthermore, 
uptitrated subjects must continue to meet those criteria throughout the study to stay on the 
uptitrated dose; if at any time a subject exceeds these thresholds (including upon retesting), they 
will be downtitrated to the lower OCA dose (10 mg).

INVESTIGATIONAL PLAN 
7.1. 
Overall Study Design 
This Phase 3, double-blind, randomized, placebo-controlled, multicenter international study will 
evaluate the efficacy and safety of OCA in subjects with a biopsy-confirmed diagnosis of 
cirrhosis (based on a fibrosis score of 4 using the NASH CRN scoring system) due to NASH 
(determined by central reading of liver histology).  Subjects with hepatic decompensation or CP 
Class B or Class C cirrhosis are excluded.  Subjects who progress to CP Class B or Class C 
during the study will discontinue investigational product but are expected to be followed through 
to study closure (or at the discretion of the Sponsor). 
Double-Blind Phase (18 Months):  Subjects will be screened for a period of up to 12 weeks 
before entering the study.  Subjects who meet the entry requirements will be randomized in a 
1:1:1 ratio to one of the three treatment arms:  once daily dosing of OCA 10 mg, OCA 
10 mg → 25 mg (ie, OCA 10 mg with uptitration to OCA 25 mg at Month 3), or placebo, in 
conjunction with local standard of care.  Uptitration will be determined based on the laboratory 
criteria and safety and tolerability assessments completed prior to Month 3 as described in 
Section 9.2.1. 
Randomized subjects will be stratified by the presence of type 2 diabetes at enrollment (yes or 
no).  Investigational product (ie, OCA or placebo) will be taken orally, with water, once daily.  
Efficacy, safety, and laboratory assessments will be evaluated at clinical visits at Day 1, monthly 
for the initial 6 months (Month 1 through Month 6 Visits), Month 9, Month 12, Month 15, and 
Month 18. 
Open-Label Extension (up to 12 Months):  Subjects who complete the Double-Blind Month 18

Double-Blind Phase will be re-randomized to either OCA 10 mg or OCA 10 mg → 25 mg 
(ie, OCA 10 mg for the first 3 months of the OLE prior to uptitrating to OCA 25 mg at OLE 
Month 3).  Uptitration will be determined based on the same criteria and assessments as employed 
in the Double-Blind Phase (Section 9.2.1).  Subjects randomized to OCA (10 mg or 10 mg → 
25 mg dose) during the Double-Blind Phase will continue the same dosing regimen they received 
at the end of the Double-Blind Phase; however, they will undergo dummy titration to maintain 
study blind until all subjects complete the Double-Blind Phase and the database is locked (refer to

7.4. 
Monitoring and Management of Potential Hepatic Injury and/or 
Disease Progression 
To monitor for potential hepatic injury, disease progression and/or hepatic decompensation, CP 
and MELD scores will be reviewed at each visit (Section 7.1.2).  In addition, adverse events, 
signs and symptoms of potential hepatic injury or decompensation, and laboratory values will 
also be reviewed at regular intervals as described in the following subsections (Section 7.4.1 to 
Section 7.4.3).  Based on the assessments of signs and symptoms of hepatic injury and liver 
biochemistry, the investigational product will be interrupted or discontinued per criteria 
discussed in Section 7.7, and close monitoring procedures will be implemented (refer to 
Section 7.4.4). 
7.4.1. 
Signs and Symptoms of Hepatic Injury or Decompensation 
The Investigator will educate each subject about recognizing the signs and symptoms of potential 
hepatic injury or decompensation and instruct each subject to contact the study site to report the 
onset of any new or worsening signs and symptoms during the study.  The Investigator will 
instruct subjects to seek immediate medical attention if they experience signs or symptoms of 
hepatic injury or decompensation. 
Appendix C provides guidance for review of signs and symptoms of hepatic injury or 
decompensation described below to be evaluated at each study visit, or as frequently as needed 
per Investigator’s discretion. 
Subjects will be evaluated at study visits for potential signs and symptoms of hepatic injury or 
decompensation: 

Protocol 747-304

Confidential and Proprietary 
Signs and Symptoms of Hepatic Injury or Decompensation: 
• Specific signs and symptoms of liver impairment:  yellowing of the skin or the whites 
of eyes, pale-colored stools, urine color change from pale to deep amber [dark] severe 
fatigue, right upper quadrant pain, rash, eosinophilia 
• More general signs and symptoms of ascites and encephalopathy:  swelling of the 
legs or abdomen, confusion, or abrupt abnormal behavior 
• Non-specific signs and symptoms of impaired health:  nausea, vomiting, abdominal 
pain, diarrhea, weight loss, fever and chills, worsening or new fatigue, weakness, loss 
of appetite 
• Significant intercurrent illnesses such as gastroenteritis may exacerbate hepatic injury 
or decompensation (eg, established severe abdominal pain, vomiting, and diarrhea) 
and should be an indication for prompt investigational product interruption and 
complete subject evaluation 
Other Symptoms: 
• New or worsening pruritus 
• Decreased urine output, urine color change, dizziness, lethargy 
Healthcare Provider (HCP) Interactions: 
• Visits to primary HCP or referral to any specialist for any new symptoms (other than 
ongoing care for stable comorbidities) 
• New medications or changes to current medications prescribed from HCP or any new 
over the counter medications or herbal supplements. 
• Laboratory procedures or assessments performed by an HCP  
Signs and symptoms for potential hepatic injury or decompensation should be followed by 
(1) evaluation of liver biochemistry for potential drug-induced liver injury (DILI) 
(Section 7.4.2), (2) assessment for disease progression (Section 7.4.3), (3) triggering of 
investigational product interruption or discontinuation per criteria (Section 7.7), 
(4) documentation in the AE eCRF or the SAE eCRFs (Section 16.1), and (5) contact with the 
medical monitor. 
7.4.2. 
Potential Drug-Induced Liver Injury 
Events of potential hepatic injury will be reviewed and adjudicated by the Hepatic Safety 
Adjudication Committee (HSAC) as described in Section 17.14.  The specific criteria for 
identification and adjudication of potential hepatic injury events are described in the HSAC 
charter. 
Liver biochemistries will be assessed at each visit to assess biochemical triggers that will prompt 
an immediate reevaluation of subjects.  Thus, these assessments will be performed at: 
• Each protocol-specified visit 
• Unscheduled visits for any safety follow-up as appropriate 

Protocol 747-304

It is important that the laboratory assessments be completed as required and that the central 
laboratory be used for assessments whenever possible.  In the event that a subject cannot return 
to the clinic for a scheduled or unscheduled visit, or there is an event that triggers a need for an 
immediate assessment, the use of a local laboratory is required.  In these cases, the Investigator 
will obtain the laboratory results and the laboratory normal ranges.  Of note, the Baseline result 
is the average of results from Screening Visits 1 and 2, Day 1, and any unscheduled visit that 
took place between Screening Visit 1 and the Day 1 Visit.  All local laboratory data, including 
the reference ranges, are to be collected and entered in the eCRF within 2 days of receiving the 
results.  For guidance on alternative processes under which subjects may complete the protocol-
specified assessments under COVID-19 restrictions refer to Section 10.  Local laboratory visits 
in conjunction with remote (telemedicine) visits are specifically encouraged in lieu of on-site 
visits where subject’s safety is of concern (eg, adverse event monitoring). 
The process for assessing criteria is presented in Figure 2, and the specific threshold(s) for each 
laboratory analyte to trigger mandatory repeat testing and potentially a complete subject 
evaluation (depending on the repeat result) are summarized in Table 3.  
ALP = alkaline phosphatase; ALT = alanine aminotransferase; BL = baseline; eCRF = Electronic Case Report Form; INR = 
international normalized ratio; IP = Investigational Product; PK = pharmacokinetic; TB = total bilirubin; ULN = upper limit of

Laboratory assessments include:  
a Signs and symptoms of hepatic injury include severe fatigue, nausea, vomiting, right upper quadrant pain, fever, 
rash, and eosinophilia. Decompensation events include variceal hemorrhage, hepatic encephalopathy, and ascites 
b Lower severity treatment-emergent threshold criteria include the following from Table 3:  In subjects with baseline ALP ≤ULN 
and treatment-emergent ALP ≥2x BL and >ULN but <250 U/L 
c If a subject is unable to return to the site for repeat test, the subject MUST have repeat (or any safety) laboratory tests performed 
at a local laboratory.  All local laboratory results, including reference ranges, should be entered in the eCRF within 2 days of 
receiving results. 
d PK sampling must be conducted within 7 days of IP interruption; close monitoring including physical exams and repeat 
laboratory testing should occur as often as deemed appropriate by the Investigator.  In subjects with signs or symptoms of 
hepatic injury or events of hepatic decompensation, the Medical Monitor should be promptly contacted upon awareness for 
consultation regarding management of the subject.

If any subject meets the triggering threshold limits indicated in Table 3 and experiences signs or 
symptoms of hepatic injury (severe fatigue, nausea, vomiting, right upper quadrant pain, fever, 
rash, eosinophilia) or events of decompensation (varices hemorrhage, hepatic encephalopathy, or 
ascites), which can be presenting features of DILI in subjects with cirrhosis, investigational 
product should be immediately interrupted (see Section 7.7 for dosing modifications).  
If no signs or symptoms of hepatic injury or decompensation are present, but liver biochemistries 
are above the triggering threshold limits, the subject should either interrupt investigational 
product or laboratory assessments including creatine phosphokinase (CPK) should be repeated 
within 2-4 days according to the threshold limits specified in Table 3.  If a repeat laboratory test 
cannot be performed within 7 days of receiving results, the subject should be instructed to 
interrupt investigational product until repeat laboratory test results have been reviewed.

If investigational product is interrupted, laboratory assessments including CPK should be 
repeated within 2-4 days of receiving results, a PK sample must be collected (within 7 days), and 
close monitoring should be initiated (repeat laboratory testing and physical exam should occur as 
often as deemed appropriate by the Investigator and these data should be entered in the eCRF 
within 2 days of receiving results).  In subjects with signs or symptoms of hepatic injury or 
events of decompensation, the Medical Monitor should be promptly contacted upon awareness 
for consultation regarding management of the subject. 
• If on repeat evaluation, in subjects who did not have investigational product 
interrupted (eg, those that had no signs and symptoms and lower severity), liver 
biochemistries are normal or below threshold values, no dosing modifications are 
required and the subject should continue to be monitored closely. 
• If on repeat evaluation, liver biochemistries remain elevated (see Table 3), 
investigational product must be interrupted for a minimum of 30 days, a PK sample 
(see below for OCA and metabolites) must be collected (within 7 days of receiving 
results), and close monitoring should be initiated (repeat laboratory testing and 
physical exam should occur as often as deemed appropriate by the Investigator and 
these data should be entered in the eCRF within 2 days of receiving results).  The 
medical monitor should be promptly contacted upon awareness for consultation 
regarding management of the subject.   
In any subject for whom investigational product is interrupted for reasons other than the inability 
to promptly repeat laboratory testing (within 7 days) for non-safety reasons, a rechallenge may 
be considered after a minimum of 30 days if liver enzymes return to below threshold values, 
there are no symptoms, lab abnormalities are determined not to be due to DILI, and if approved 
by the Medical Monitor and Investigator.  If investigational product is restarted after 30 days, 
liver biochemistries should be repeated within 2 to 4 days and close monitoring should be 
continued.   
If the liver enzymes do not return to below threshold values after 30 days and the Investigator 
considers that the event has not resolved, the Investigator should consult with the Medical 
Monitor to determine a treatment plan.  This may include continuing close monitoring with 
interruption or discontinuing investigational product. 
For all subjects whose investigational product is interrupted or discontinued, and close 
monitoring is initiated, a follow up assessment of the subject’s status should be performed at 
study completion. 
Subjects should, wherever possible, come back to the site.  It may be difficult for subjects who 
are distant from their study site to return to the site promptly.  Such subjects must have repeat (or 
any safety) laboratory tests performed at a local laboratory, but normal laboratory ranges and the 
results should be made available to the Investigator All local laboratory data, including reference 
ranges, should be entered in the eCRF within 2 days of receiving the results.  For guidance on 
alternative processes under which subjects may complete the protocol-specified assessments 
under COVID-19 restrictions refer to Section 10. 
It should be noted that it is difficult to recognize every potential marker of hepatic deterioration.  
There is no substitute for good medical judgment.  Investigators will be reminded to be cautious 
and mindful in their evaluation of subjects’ symptoms, signs, and laboratory results.  However,

for example, a single abnormal laboratory analyte result may be artefactual; accordingly, 
Investigators will be allowed to implement an alternate follow-up procedure if considered 
appropriate based on their medical judgement but only after documented agreement with the 
Sponsor’s medical monitor.  
Specific aspects of the Potential DILI Management Algorithm may be adjusted, in which case 
specific guidelines will be provided to the sites for implementation. 
7.4.3. 
Progression of Disease to Child-Pugh Class B or C 
Investigators will closely monitor subjects for potential progression of cirrhosis to CP Class B or 
Class C at every visit (or at unscheduled visits in the event of signs or symptoms of potential 
hepatic injury or decompensation).  Assessment of CP Scores must be performed at every visit.  
Refer to Section 7.4.3.1 for determination of CP Score.  Investigational product discontinuation 
is required in subjects who progress to CP score of 7 or higher. 
7.4.3.1. 
Child-Pugh Assessment 
CP Score (Pugh 1973, Lucey 1997) is calculated and reported within the EDC system based on 
data entered into the eCRF by adding the scores from the 5 factors outlined in Table 4 and can 
range from 5 to 15.  The investigational product should be discontinued in subjects with CP 
score ≥7.  
Calculation of the CP Score includes Investigator assessments of ascites and hepatic 
encephalopathy, which may be assessed during the adverse event review at the scheduled visits, 
as well as total bilirubin, serum albumin, and prothrombin time, which should be collected at the 
same visit.  The relationship of CP Score to disease progression is as follows: CP score 5-6 = CP 
Class A; CP Score 7-9 = CP Class B; CP Score ≥10 = CP Class C.

Model for End-Stage Liver Disease (MELD) Scoring 
MELD is a scoring system used to assess the severity of chronic liver disease.  An increasing 
MELD score is associated with increased severity of hepatic dysfunction and increased 3-month 
mortality risk.  MELD scores will be calculated based on creatinine, bilirubin, INR, and serum 
sodium values as appropriate, collected at the same visit with modification by United Network 
for Organ Sharing.  If only 1 component of MELD needs to be repeated, all other components 
should also be repeated.  INR will be calculated based on PT value by the central laboratory.  
The MELD calculation adjusts for subject who have had 2 or more dialysis treatments within the 
prior week and will automatically assign a serum creatinine of 4.0 mg/dL for these subjects.  
7.4.4. 
Close Observation 
The Investigator should consistently and frequently assess individual subjects who meet the 
above criteria to determine on an ongoing basis the totality of a subject’s clinical profile, which 
includes careful evaluation of signs and symptoms of potential hepatic injury or decompensation 
coupled with rules-based laboratory monitoring.  If investigational product is interrupted or 
discontinued as described in Section 7.7, subjects should continue to be closely monitored based 
on the clinical judgement of the Investigator and evaluated for signs and symptoms of potential 
hepatic injury.  In the event of potential hepatic injury, the subject should be promptly brought 
into the clinic and undergo a complete evaluation (laboratory assessments, physical 
examinations, and review of signs and symptoms).  Subjects who permanently discontinue from 
investigational product are not required to undergo additional safety visits provided stabilization

7.4.5. 
Pruritus 
Pruritus is already being closely monitored but has not been shown to be a reliable predictor of 
hepatic injury.  However, Investigators should be vigilant in responding to subjects’ complaints 
of new or worsening pruritus symptoms with prompt follow-up.  Pruritus grading (as with all 
adverse events) should be performed in accordance with the current version of the Common 
Terminology Criteria for Adverse Events (CTCAE;Appendix D). 
For subjects with Grade 3 pruritus per the current version of the CTCAE (Section 16.1.6.1), 
instruct the subject to discontinue investigational product (Table 5).  These subjects should 
continue to return for scheduled study visits for safety follow up; however, the subjects will not 
be rechallenged with investigational product.  General guidance for the management of subjects 
experiencing significant pruritus (≤ Grade 2) is provided in Section 16.1.6.1. 
7.5. 
Medical Management of Subjects with Symptomatic Cholelithiasis 
and/or Cholecystitis or Pancreatitis 
7.5.1. 
Symptomatic Cholelithiasis and/or Cholecystitis 
NASH is associated with several known risk factors for cholelithiasis, such as obesity, type 2 
diabetes, and other metabolic abnormalities.  The prevalence of gallstone disease in NASH is 
higher than in the general population.  The majority of gallstones are asymptomatic and may 
never become symptomatic (Sakorafas 2007, Stinton 2012). 
Because symptomatic events of cholelithiasis and/or cholecystitis may develop in subjects with 
or without a known history of gallstones, it is important that all subjects be (1) monitored for 
signs and symptoms suggestive of gallstone disease and (2) counseled to recognize and seek 
immediate medical attention if they experience symptoms suggestive of cholelithiasis and/or 
cholecystitis.  
Subjects who develop signs or symptoms suggestive of symptomatic cholelithiasis (refer to 
Appendix C) and/or complications related to gallstone disease (eg, cholecystitis) should have 
investigational product interrupted while undergoing further evaluation consistent with the local 
standard of care and management until complete resolution, including potential surgical 
intervention.   
Post-cholecystectomy, subjects should be monitored for full resolution and may resume 
investigational product after approval from the Investigator and Medical Monitor (see 
Section 7.7). 
If upon surgical evaluation, it is deemed that the subject does not need to undergo surgery, the 
subject may re-initiate investigational product upon resolution of symptoms and approval from 
the Investigator and Medical Monitor. 
7.5.2. 
Pancreatitis 
Pancreatitis is a serious and potentially fatal condition most commonly caused by gallstones or 
alcohol. 
Because symptoms of acute pancreatitis and acute cholecystitis may be similar, subjects 
presenting with significant upper abdominal pain with nausea, vomiting, fever, or jaundice 

Protocol 747-304 
Version 7.0:  16Jun2021
 
Page 64
 
Confidential and Proprietary 
should be evaluated for both cholecystitis and pancreatitis, consistent with the local standard of 
care (eg, amylase and lipase laboratory tests and/or imaging assessments). 
Investigational product must be permanently discontinued in any subject diagnosed with 
treatment-emergent acute, or nonacute (chronic or recurrent) pancreatitis (see Section 7.7).  
The evidence used to diagnose pancreatitis, including symptoms, laboratory test results, and/or 
imaging results, must be collected.  If a subject is suspected to have acute pancreatitis or 
develops signs and symptoms consistent with acute pancreatitis, amylase and lipase levels should 
be monitored for 3 months after the onset of symptoms per local standard of care.  The 
Investigator should contact the Medical Monitor upon awareness of treatment-emergent acute or 
nonacute pancreatitis.   
Investigational product discontinuation is not required for subjects who have a medical history of 
pancreatitis and have not experienced recurrence of pancreatitis since enrollment into the study.  
Any subject who meets the requirements for investigational product discontinuation should be 
encouraged to remain in the study and complete all protocol‐specific assessments as defined, 
after stopping investigational product. 
7.6. 
Monitoring for Renal Impairment and Nephrolithiasis 
7.6.1. 
Renal Impairment 
AKI is a serious medical condition that may lead to chronic kidney disease or kidney failure; 
therefore, it is important to identify and monitor subjects for signs or symptoms suggestive of 
AKI for appropriate management.  Investigators are instructed to evaluate for symptoms 
suggestive of AKI such as new onset fatigue/asthenia, nausea, or confusion and to assess signs 
such as decreased skin turgor (dehydration), increased heart rate, lower extremity edema, 
decrease urine output or dark urine at each visit.   
As AKI is defined by an abrupt decrease in renal function, the Sponsor recognizes that local labs 
will be required to be recorded as well as all central lab data (scheduled or unscheduled visits) to 
adequately capture events.  Repeat laboratory assessments should include albumin, serum 
chemistry (creatinine, BUN, electrolytes), urinalysis with microscopic examination, and 
assessment of eGFR.  All local lab data, including reference ranges, are required to be entered in 
the eCRF within 2 days of receiving results. 
The threshold criteria used to identify and monitor subjects for potential renal impairment and 
the actions to be taken with investigational product are outlined in Figure 3.  
Baseline serum creatinine values, which will inform the subsequent decisions on monitoring for 
and management of renal injury, are defined as the average of serum creatinine values from the 
two most recent study visits (scheduled and unscheduled), that are not associated with a renal-
related AE or an acute increase. 

Protocol 747-304 
Version 7.0:  16Jun2021

If a subject meets the threshold criteria, a prompt re-evaluation (within 48 hours) should take 
place.  Subjects should, when possible, return to the study site for re-evaluation.  It may be 
difficult for subjects who are distant from their study site to return to the site promptly.  Such 
subjects must have repeat (or any safety) laboratory tests performed at a local laboratory, but the 
laboratory reference ranges and the results should be made available to the Investigator.  All 
local laboratory data, including reference ranges, should be entered into the eCRF within 2 days 
of receiving the results.

• If on repeat testing, serum creatinine has returned to below threshold values, no 
dosing modifications are required. 
• If on repeat testing, serum creatinine remains elevated a comprehensive evaluation 
including the subject’s recent medical history, changes in medication, health status, 
and intercurrent illness should be conducted.  If no alternative cause of serum 
creatinine elevation can be identified investigational product should be interrupted 
and close monitoring should be initiated.  Close monitoring includes repeat labs and 
physical exam, which should occur as often as deemed appropriate by the 
Investigator, and these data should be entered in to the eCRF within 2 days of 
receiving results.  If deemed appropriate by the Investigator, the subject may be 
referred to a nephrologist. 
In any subject for whom investigational product is interrupted for reasons other than inability to 
promptly repeat laboratory assessments for non-safety reasons: 
• The event will be treated as a potential case of AKI and will be sent for review and 
adjudication by the Renal Adjudication Committee (described in Section 17.11.2).  
The specific criteria for identification and adjudication of potential AKI events are 
described in the Renal Adjudication Committee charter. 
• A PK sample must be collected within 7 days of investigational product interruption.  
If a PK sample cannot be collected within 7 days, the reason should be recorded in 
the eCRF. 
• A rechallenge may be considered after a minimum of 30 days if serum creatinine 
returns to below threshold values and if approved by the Medical Monitor and 
Investigator.  If serum creatinine remains above threshold values after 30 days, the 
subject should be referred to a nephrologist for further evaluation. 
7.6.2. 
Nephrolithiasis 
The development of signs or symptoms suggestive of kidney stones (nephrolithiasis) should be 
monitored.  Standard of care including adherence to recommended dietary measures, adequate 
fluid intake, and other measures prescribed should be employed to prevent recurrent episodes of 
kidney stones (Pearle 2014).  Subjects should be asked if they have experienced symptoms of 
nephrolithiasis (eg, evidence of hematuria or flank pain).  Nephrolithiasis should be considered 
in subjects with evidence of microscopic hematuria without other symptoms.   
Subjects who develop kidney stones during the study will be further evaluated according to 
guidelines to collect serum electrolytes, uric acid, and a urinalysis with microscopic examination 
(Pearle 2014).  All local laboratory data, including reference ranges, should be entered into the 
eCRF within 2 days of receiving the results.  Every effort should be made to collect the kidney 
stone for analysis.  Subjects should be referred to a urologist or nephrologist for further 
evaluation of the nephrolithiasis, including the etiology as appropriate.

Investigational Product Dosage Interruption, Downtitration, 
Discontinuation, and Rechallenge Criteria 
Dosages for investigational product should be maintained constant during the study.  However, 
interruptions, downtitration, discontinuation, and any rechallenge of investigational product 
should be implemented per the criteria outlined in Table 5.  Planned uptitration at Month 3 in the 
OCA 10 mg → 25 mg arm (Double-Blind Phase) and in placebo subjects at OLE Month 3 is 
described in Section 9.2. 
Subjects can be temporarily or permanently discontinued from investigational product by the 
Investigator at any time for clinical safety concerns.  If investigational product is temporarily or 
permanently discontinued, a PK sample must be collected within 7 days.  If a PK sample cannot 
be collected within 7 days, the reason should be recorded in the eCRF. 
• Subjects who are temporarily discontinued from investigational product are expected 
to continue in the study and should follow the regular visit schedule for the duration 
of the study. 
• Subjects who permanently discontinue from investigational product are expected to 
continue in the study and should follow the regular visit schedule for the duration of 
the study.  These subjects will not be rechallenged with investigational product.  
Prior to re-starting investigational product after a prolonged interruption, the subject must be 
re-consented and new baseline visit procedures must be performed (refer to Section 8.2.2) if the 
interval from the last visit was more than 3 months (+2 weeks). 
Investigational product should not be interrupted in the following instances:  1) in subjects who 
experience an event that is not symptomatic (such as an incidental finding of gallstones during an 
ultrasound exam);  2) in subjects who previously experienced an event of symptomatic 
cholelithiasis and/or cholecystitis and have either undergone a cholecystectomy (and have no 
symptoms suggestive of retained or recurrent bile duct stones) or upon surgical consultation does 
not need to undergo surgery, and in whom symptoms have fully resolved at the present time 
while on investigational product;  or 3) in subjects who have a past medical history of 
pancreatitis and have not experienced a recurrence of pancreatitis since enrollment into the study.

Criteria for Study Termination 
The Sponsor reserves the right to terminate the study at any time.  It is normal procedure to 
review the emerging clinical and safety data.  As a result of such a review or a recommendation 
by the Data Monitoring Committee (DMC), it may be necessary to stop the study before all 
subjects have completed the study.  In addition, the Sponsor may terminate the study at an 
investigational site at any time (eg, Good Clinical Practice [GCP] noncompliance or 
poorly performing sites, as determined by the number of subjects enrolled or the quality of the 
study data). 
The Investigator and/or Sponsor (or designee) must notify the Institutional Review 
Board/Independent Ethics Committee (IRB/IEC) of discontinuation of a site or the study and the 
reason for doing so. 
Investigators will be informed by the Sponsor as to when the final study visit is to be completed 
and should then schedule all subjects for the end of study (EOS) Visit.

SELECTION AND WITHDRAWAL OF SUBJECTS 
8.1. 
Subject Population 
This study will be conducted at approximately 300 international study sites with experience in 
treating patients with compensated cirrhosis due to NASH.  Prospective subjects will be 
identified primarily from the hospital and/or physician’s database of patients with NASH or may 
be referred from other physicians.  Subjects may self-refer to an Investigator if they become 
aware of the study through local, national, or international NASH patient societies, forums, or 
networks.

8.1.1. 
Subject Inclusion Criteria 
1. Subjects ≥18 years of age 
2. Subjects with a confirmed diagnosis of NASH and a fibrosis score of 4 based upon the 
NASH CRN scoring system determined by central reading of a liver biopsy obtained no 
more than 12 months before Day 1 
3. Contraception:  Female subjects of childbearing potential must use ≥1 effective method 
(≤1% failure rate) of contraception during the study until 4 weeks following the last dose 
of investigational product (including OLE doses).  Female subjects are considered as 
being of childbearing potential, ie, fertile, following menarche and until becoming 
postmenopausal, unless permanently sterile.  Permanent sterilization methods include 
hysterectomy, bilateral salpingectomy, and bilateral oophorectomy.  A postmenopausal 
state is defined as no menses for 12 months without an alternative medical cause.  A high 
follicle stimulating hormone (FSH) level in the postmenopausal range may be used to 
confirm a post-menopausal state in women not using hormonal contraception or 
hormonal replacement therapy.  However, in the absence of 12 months of amenorrhea, a 
single FSH measurement is insufficient. 
Effective methods of contraception are listed below (refer to Section 9.9 for highly 
effective contraceptive methods): 
− Barrier method, ie, (a) condom (male or female) with spermicide or (b) diaphragm 
with spermicide; or 
− Intrauterine device; or 
− Vasectomy (partner); or 
− Hormonal (eg, contraceptive pill, patch, intramuscular implant or injection); or 
− Abstinence, if in line with the preferred and usual lifestyle of the subject (where 
abstinence is defined as refraining from heterosexual intercourse)  
4. Must provide written informed consent and agree to comply with the study protocol 
8.1.2. 
Subject Exclusion Criteria 
Criteria with exclusionary laboratory values are to be based on the most recent laboratory result 
available prior to randomization.  For alanine aminotransferase (ALT), aspartate 
aminotransferase (AST), or total bilirubin (conjugated bilirubin for subjects with an established 
diagnosis of Gilbert’s syndrome), if the Screening Visit 2 value is ≥30% higher than the 
Screening Visit 1 value and > the upper limit of normal (ULN), then a third measurement must 
be obtained at an unscheduled visit.  Subjects who satisfy any of the following exclusion criteria 
will be ineligible for enrollment:

8.2. 
Subject Withdrawal Criteria 
Subjects can be discontinued from investigational product by the Investigator at any time for 
clinical safety concerns.  Subjects who are discontinued from investigational product are 
expected to continue in the study and should follow the regular visit schedule for the duration of 
the study phase (Double-Blind or OLE).  Subjects who permanently discontinue from 
investigational product are expected to continue regular visit schedule for safety assessments 
until stabilization of the clinical event has occurred leading to discontinuation (per discretion of 
the Investigator and upon discussion with the medical monitor). 
Refer to Section 7.7 for withdrawal criteria related to potential hepatic injury and/or 
decompensation; progression to cirrhosis with CP score ≥7; treatment-emergent acute or 
nonacute pancreatitis; ≥Grade 3 pruritus, AEs ≥Grade 3 in severity and possibly, probably, or 
definitely related to investigational product; AEs ≥Grade 4 in severity and NOT or unlikely 
related to investigational product; liver transplantation, bariatric surgery, and pregnancy.  Other 
reasons, including withdrawal of consent or lost to follow-up and withdrawal from 
 
substudy, are described in Section 8.2.1 below.

8.2.1. 
Other Reasons for Discontinuation of Investigational Product or Study 
Termination 
Subjects who discontinue investigational product are expected to continue in the study until the 
end of the study.  If a subject experiences a suspected clinical outcomes event, he or she should 
continue the regular visit schedule and continue taking investigational product as long as the 
Investigator assesses it as safe.  Subjects who discontinue investigational product prior to 
completion of the study need to also continue to follow the regular visit schedule through study 
completion (Month 18 for the Double-Blind Phase or Month 12 for the OLE phase).  In general, 
subjects should be strongly encouraged to both stay on investigational product and remain in the 
study until study completion.  Early termination procedures should only be conducted if the 
subject withdraws consent (see Section 9.10.15).  
The following events are considered appropriate reasons for a subject to discontinue 
investigational product; however, these subjects are expected to continue in the study until study 
termination (or at the discretion of the Sponsor). 
• The Investigator or Sponsor considers that it is advisable or in the best interest of the 
subject. 
• Modification of consent: 
− Consent may be modified to discontinue study visits but allow periodic telephone 
contact of the subject (in line with the study visit schedule) through completion of 
the study (Month 18 if initiated in the Double-Blind Phase or Month 12 if initiated 
in the OLE phase), through the subject’s primary care physician, or personal 
contacts who can provide information on behalf of the subject by the Investigator 
− Consent may be modified to discontinue study visits but allow continued access to 
medical records through completion of the study (Month 18 if initiated in the 
Double-Blind Phase or Month 12 if initiated in the OLE phase) to assess for 
potential MACE, and liver-related clinical outcomes 
• Lost to Follow-Up 
• Pregnancy 
• The occurrence of clinical or laboratory AEs considered by the Investigator to be 
clinically important 
• There is a major violation of the clinical study protocol  
• The development of any exclusion criteria that might jeopardize safety (Section 8.1.2) 
The Investigator is encouraged to contact the Sponsor prior to discontinuing a subject from 
treatment.  The Investigator must notify the Sponsor study monitor by telephone or email as soon 
as possible if any subject prematurely withdraws from the study. 
It is agreed that, for reasonable cause, either the Investigator or the Sponsor, may terminate this 
study.

8.2.1.2. 
Withdrawal of Consent to Continue in the Study 
If the subject decides that it is in his/her best interest to discontinue from the study, he or she 
may withdraw consent.  It is fully understood that all subjects volunteer for the study and that 
they may withdraw their consent to continue in the study at any time. 
A reasonable effort must be made to determine the reason(s) for subject discontinuation.  This 
information and date of contact must be recorded in the appropriate eCRF. 
8.2.1.3. 
Lost to Follow-Up 
If a subject fails to return to the clinic for a study visit, and the Investigator ceases to have 
contact with the subject, he or she will be withdrawn from the study.  Subjects will be considered 
“lost to follow-up” only after reasonable, documented attempts to reach the subject prove 
unsuccessful.

subject fails to return for a study visit or is lost to follow-up.  This information and date of 
contact must be recorded in the appropriate eCRF. 
8.2.1.4. 
Pregnancy 
Whenever the site is notified of a possible pregnancy, the subject should be asked to come in for 
an unscheduled visit to perform a serum pregnancy test.  If a female subject becomes pregnant, 
the subject must stop taking investigational product immediately but will be encouraged to 
continue study visits until the end of the study.  The subject must be followed by the Investigator 
through pregnancy outcome.  The mother (and infant) will be followed as considered appropriate 
by the Investigator and the Medical Monitor.  As described in Section 16.1.13, a pregnancy is not 
considered an AE for reporting purposes. 
8.2.2. 
Reinitiating Investigational Product After Interruption 
Prior to restarting investigational product after a prolonged interruption (ie, longer than 3 months 
[+2 weeks]), the subject must be reconsented and the procedures listed below must be performed 
before the subject re-starts investigational product regardless of the reason for interruption.   
The following procedures will be performed to reinitiate investigational product: 
• Review Informed Consent Form (ICF) and obtain signatures before performing the 
repeat baseline procedures 
• Verify that the subject has fasted for at least 8 hours 
− Record fasting status in the source and electronic case report form (eCRF) 
− If the subject reports having eaten within 8 hours, document accordingly in the 
source and eCRF and remind the subject that fasting is required before all study 
visits 
• Record current concomitant medications  
• Assess and record AEs 
• Record vital signs (body temperature, sitting heart rate, respiratory rate, and seated 
blood pressure after sitting 3 minutes) 
• Record weight and BMI 
• Conduct physical exam 
• Perform standard 12-lead ECG  
• AUDIT, smoking habits, and caffeine consumption 
• Health-related quality of life questionnaires and health status for the assessment of 
health utilities 
• Perform hepatobiliary ultrasound for HCC screening unless data from a recent 
ultrasound (within 3 months) are available 
• Obtain blood samples for:

− HCC screening (alpha-fetoprotein [AFP]) 
− Serum chemistry, hematology, and coagulation  
− Metabolic parameters 
− Lipoprotein analysis 
− Markers of inflammation, apoptosis, and necrosis 
− PD assessments 
• Calculations will be performed by the Sponsor or designee for: 
− MELD Score 
− CP Score/Class 
− Noninvasive scores of liver fibrosis (NAFLD fibrosis score [NFS], Fibrosis-4 
[FIB-4], and aspartate aminotransferase to platelet ratio index [APRI]) 
− Noninvasive panel of liver fibrosis (ELF and FibroMeter) 
− Cardiovascular risk scores (10-year ASCVD Risk, Framingham Risk Score 
[FRS], Reynolds score, SCORE) 
• Noninvasive radiological liver fibrosis measurement (transient elastography [TE]; 
conducted at sites where device is available). 
• Obtain urine sample for urinalysis 
• Perform a urine-based β-hCG pregnancy test for females of childbearing potential 
• Record the visit in the randomized and trial supply management system (RTSM) and 
dispense investigational product 
• Administer investigational product at the study site.  Instruct the subject to swallow 
the tablet whole with water; s/he must not chew, divide, or crush the tablet. 
• Schedule the next visit, reiterate dosing instructions, and advise the subject: 
− Take the investigational product at approximately the same time each day  
− NOT to take investigational product on the morning of the next visit  
− To bring the investigational product bottle(s) with them to his/her next visit; s/he 
will dose at the clinic 
− To fast overnight (at least 8 hours) before the next visit, but water is permitted 
8.2.3. 
Subject Discontinuation Notification 
The Investigator must notify the Sponsor as soon as possible if any subject prematurely 
discontinues from the study.  The date when the subject is withdrawn and the primary reason(s) 
for discontinuation must be recorded in the eCRF; additional information may be requested by 
the Sponsor to complete a discontinuation narrative.  Subjects will be considered “lost to 
follow-up” only after reasonable, documented attempts to reach the subject prove unsuccessful.

In all cases, a reasonable effort must be made to determine the reason(s) that a subject fails to 
return for required study visits or discontinues from the study.  This information must be 
documented in the eCRF. 
If a subject is withdrawn from the study early (regardless of the cause), all of the early 
termination (ET) evaluations are to be performed at the time of withdrawal, to the extent 
possible. 
9. 
TREATMENT OF SUBJECTS 
9.1. 
Investigational Product Treatment Regimen 
The term investigational product (provided as part of this clinical study) refers to either OCA or 
placebo. 
Three treatment groups will be evaluated: 
• Placebo 
• OCA (10 mg) 
• OCA (10 mg → 25 mg) 
Each dose will be made up of 1 tablet. 
Investigational product will be taken orally with water, once daily for the duration of the study.  
Subjects will be instructed to begin dosing on Day 1 and are to take investigational product at 
approximately the same time each day.  Subjects must be instructed to swallow the tablet whole; 
they must not chew, divide, or crush the tablet. 
At each study visit where the daily dose of investigational product is administered at the site, all 
assessments, except for the post-dose collection of blood samples for the subjects participating in 
the optional serial PK assessment and/or 
, must be completed 
before administration of investigational product. 
Investigational product during the OLE Phase will be provided as open-label OCA tablets.  The 
study will be blinded until the last subject completes the Double-Blind Phase and the database is 
locked. 
9.2. 
Criteria for Uptitration 
9.2.1. 
Double-Blind Phase (Month 3) 
Subjects randomized to the OCA 10 mg → 25 mg arm in the Double-Blind Phase will receive 
OCA 10 mg for the first 3 months.   
Prior to the Month 3 study visit, the Medical Monitor will perform a subject-level consolidated 
review of safety data, including data from the Month 1 and 2 study visits, as well as that from 
any unscheduled visit(s), for all study subjects.  Case review and discussion with the Principal 
Investigator will occur as needed.  The review will include but not be limited to the following: 
• Liver-related adverse events 

Protocol 747-304 
Version 7.0:  16Jun2021
 
Page 79
 
Confidential and Proprietary 
• Safety laboratories:  chemistry panel including glucose, hematology panel, 
coagulation parameters; computed MELD score and CP score 
• Physical examination (development of clinically evident ascites or manifestations of 
hepatic encephalopathy) 
Additional considerations to determine the suitability to uptitrate will include an assessment of 
comorbid conditions, the subject’s overall adverse event profile, concomitant medications with a 
focus on potentially hepatotoxic concomitant medications, and/or any new treatment(s) for 
comorbid condition(s).  A subject may be considered for uptitration to OCA 25 mg if no safety 
and/or tolerability concerns are evident in the clinical judgement of the reviewer(s).  If 
uptitration at Month 3 is not feasible, the window for uptitration may be extended by up to one 
calendar month, after consultation and agreement with the Medical Monitor.  The uptitration 
review process is detailed in the study-specific Medical Management Plan. 
Only those subjects who meet all of the following criteria will be eligible for uptitration at 
Month 3: 
• Total bilirubin ≤1.2 mg/dL, serum albumin ≥3.5 g/dL, INR <1.5, and platelet count 
>100,000/mm3 at baseline, and at all visits prior to Month 3 (including any 
unscheduled visits). 
• Medical Monitor approval following a safety and tolerability assessment as described 
above.  
Subjects who do not meet these criteria will not be uptitrated for the remainder of the study. 
If at any time during the study, a subject who has undergone uptitration has total bilirubin 
>1.2 mg/dL, serum albumin <3.5 g/dL, INR ≥1.5, or platelet count ≤100,000/mm3, the laboratory 
assessment(s) should be repeated within 7 days.  If upon repeat evaluation, value(s) remain 
outside the specified criteria, investigational product should be downtitrated to a maximum daily 
dose of OCA 10 mg and the Medical Monitor should be notified promptly (see Table 5).  
Subjects randomized to the OCA 10 mg or placebo arms will undergo dummy titration to 
maintain study blind.  All uptitration and downtitration will be implemented in a blinded fashion 
within RTSM to maintain the integrity of the study blind. 
Dosing frequency post-titration may be temporarily decreased for tolerability reasons, following 
discussions with the Medical Monitor.   
In addition, investigational product may be interrupted per safety criteria listed in Table 5 and 
Section 7.7.  The procedures for re-initiating investigational product after prolonged interruption 
are provided in Section 8.2.2. 
9.2.2. 
OLE Phase 
Subjects who were randomized to placebo in the Double-Blind Phase will be re-randomized to 
either OCA 10 mg or OCA 10 mg → 25 mg at entry into the OLE.  Uptitration to OCA 25 mg at 
Month 3 in the OLE will be determined based on the same criteria and assessments employed in 
the Double-Blind Phase and described above.  Subjects randomized to OCA (10 mg or 10 mg → 
25 mg dose) during the Double-Blind Phase will continue the same dosing regimen. 

Protocol 747-304

Confidential and Proprietary 
All dosing, uptitration, and downtitration will be conducted in a blinded fashion in order to 
maintain the integrity of the study blind until all subjects complete the Double-Blind Phase and 
the database is locked. 
9.3. 
Criteria for Extension of Double-Blind Treatment with 
Investigational Product 
With the exception of sites in the Ukraine, for subjects who have been unable to complete the 
liver biopsy procedure at the Month 18 Visit due to the limitations caused by the COVID-19 
pandemic and have or will run out of investigational product, investigational product may be 
extended beyond the Month 18 Visit for a maximum of 3 additional months of the double-blind 
period.  In order for a subject to be eligible for this extension, the following must occur: 
• Assessment of safety laboratory tests (chemistry panel including glucose, hematology 
panel, coagulation parameters; computed MELD score, and CP score) at Month 18, 
with review of results by the Medical Monitor and Investigator.  
• Assessment of subject status at the Month 18 Visit must occur, either via an onsite 
study visit (if possible) or via a telemedicine visit (“virtual visit”) as an alternative 
means of enabling Investigators and site staff to evaluate subject status and record 
any AEs or new medications.  At a minimum, these visits must consist of a direct 
telephone or videocall discussion with the subject by the Investigator or an 
appropriate designee from the Investigator’s team who is currently authorized to 
undertake examinations on the Investigator’s Delegation of Authority Log.  If an 
onsite visit or a telemedicine contact is not feasible (eg, no access to the subject) to 
assess status, investigational product will not be dispensed. 
• If deemed necessary, additional assessment of safety laboratory tests and/or subject 
status may be performed at the discretion of the Investigator or Medical Monitor.  
Based on the individual subject-level safety and tolerability assessment, if both the 
Medical Monitor and the Investigator agree that the benefit-risk profile remains 
favorable, investigational product may be dispensed, which will provide an additional 
3 months of treatment.   
Unless all of the above measures occur, additional investigational product will not be provided. 
9.4. 
Standard of Care and Concomitant Medications 
Concomitant medications will be used at the discretion of the usual care provider (or Investigator 
if also the usual care provider).  Relevant information about all concomitant medications taken 
before (ie, within 12 months of Day 1) and during the study must be recorded in the source 
documents and case report form, as well as any dose or dose regimen changes that occur during 
the study.  All subjects will be questioned about concomitant medications at each clinic visit.  To 
the extent possible, concomitant medications should be maintained at a stable dose throughout 
the study and at a minimum, from Day 1 through the end of the Double-Blind Phase, unless the 
baseline therapy is no longer considered clinically appropriate by the Investigator or the subject’s 
primary care provider.  In general, Investigators will be encouraged to follow guidelines for care

based upon local and institutional practice patterns and any relevant published practice 
guidelines.  
Subjects must follow the medication restrictions outlined in the inclusion and exclusion criteria 
(Section 8) during the study.  The restrictions related to use of drugs historically associated with 
drug-induced NAFLD are as follows: 
• Drugs with Potential NASH-modifying Properties 
Subjects should either not be taking any drugs with potential NASH-modifying 
properties (specifically, TZDs/glitazones, vitamin E, or glucagon-like peptide-1 
agonists) or be on a stable dose of these medications for 6 months before Day 1.  
Subjects providing historical biopsies to determine study eligibility should be on a 
stable dose of these medications for 12 months before Day 1 and these medications 
should not have been initiated after the historical liver biopsy was performed.  
Changes to these drugs with potential NASH-modifying properties are not permitted 
for the duration of the Double-blind Phase unless the baseline therapy is no longer 
considered clinically appropriate by the Investigator/or the usual care provider. 
• Drugs with Potential NAFLD-inducing Properties 
Subjects chronically (≥12 months) using the following drugs that are historically 
associated with NAFLD will not be enrolled in the study if used within the 5 years 
before Day 1:  amiodarone, methotrexate, systemic glucocorticoids [unless used at 
physiologic replacement doses for the treatment of adrenal insufficiency], 
tetracyclines, tamoxifen, estrogens at doses greater than those used for hormone 
replacement, anabolic steroids [except for testosterone preparations used at 
physiologic replacement doses for the treatment of documented hypogonadism], 
valproic acid, and other known hepatotoxins (refer to Exclusion Criterion 28; 
Section 8.1.2). 
If a study subject receives a COVID-19 vaccination, the date(s) of vaccination, vaccine name, 
and manufacturer should be recorded as a concomitant medication for each dose (refer to 
Section 10). 
9.4.1. 
LDL-Lowering Medications 
Appendix A provides a general guidance for cholesterol management including monitoring, 
triggers for intervention, and treatment goals.  Use of LDL-lowering medications 
(eg, simvastatin, atorvastatin, PCSK9 inhibitors) should be at a stable dose ≥30 days before 
Day 1.  During the study, changes to LDL-lowering medication regimen are allowed, given the 
potential increase in total and LDL cholesterol following treatment with OCA. 
9.4.2. 
Warfarin 
Taken concomitantly, OCA and warfarin may decrease INR, thus INR should be monitored and 
the dosage of warfarin adjusted, as needed, to maintain the target INR range.

9.4.3. 
Bile Acid Sequestrants 
Bile acid sequestrants (BAS) have the potential to bind to fat-soluble vitamins, hormones, or 
medications.  Subjects taking BAS (including colestyramine and its derivatives, colestipol, 
colesevelam, or other BAS) or aluminum hydroxide- or smectite-containing antacids should be 
instructed to stagger their dosing of investigational product in temporal relationship to these 
agents, ensuring at least 4 hours between doses of the BAS and/or these antacids and the 
investigational product (ie, BAS should be administered 4 hours before or 4 hours after 
investigational product administration).  For guidance on using BAS to treat pruritus ≤Grade 2 in 
severity refer to Section 16.1.6.1. 
Due to the potential of BAS to affect the disposition of OCA, long-term use of BAS should be 
avoided where possible while taking investigational product.  In subjects taking long-term BAS 
for other medical conditions (eg, hypercholesteremia), other therapies to replace the BAS should 
be considered.   
9.4.4. 
Drug-Drug Interaction 
The effect of OCA on drug metabolizing enzymes has been evaluated in both in vitro and clinical 
studies.  The PK profile of caffeine, a sensitive CYP1A2 substrate, showed a weak effect of 
OCA on CYP1A2.  Based on these results, OCA may increase the exposure of narrow 
therapeutic index drugs that are substrates for CYP1A2, such as theophylline and tizanidine. 
9.4.5. 
Standard of Care: Management of Dyslipidemia 
Given the prevalence of dyslipidemia in patients with NASH and the potential increase in total 
cholesterol and LDLc following treatment with OCA, it is recommended that Investigators 
proactively monitor and manage lipid levels in all subjects as indicated via appropriate medicinal 
interventions (eg, statins).  Recent guidelines stress the importance of evaluating ASCVD risk in 
all patients to help guide decisions in recommending therapies and reducing LDLc to reduce the 
risk and prevent onset or recurrence of ASCVD.  As such, reducing lipids, particularly LDLc, are 
part of a comprehensive CV risk reduction strategy.  Results from meta-analyses have confirmed 
the dose-dependent reduction in ASCVD with LDLc-lowering agents; the greater the absolute 
LDLc reduction, the greater the CV risk reduction.  Recent guidelines for the management of 
lipids, such as the 2019 ESC/EAS Guidelines (Mach 2020), suggest that LDLc targets should be 
individualized based on available treatments and each subject’s overall ASCVD risk profile.  The 
targeted approach to lipid management is aimed at reducing atherosclerotic risk by substantially 
lowering LDLc to levels that have been achieved in recent large-scale trials (Figure 4).

9.4.6. 
Standard of Care: Management of Hyperglycemia 
Subjects with type 2 diabetes mellitus and those who are at risk for developing hyperglycemia 
should be closely monitored throughout the study in order to ensure appropriate therapeutic 
interventions based on current guidelines to mitigate potential elevations of serum glucose and 
initiate them when indicated.  The Investigator should proactively consider major risk factors for 
developing hyperglycemia that include family history of type 2 diabetes; obesity; African 
American, Native American, Hispanic or Asian American heritage; hypertension; dyslipidemia; 
or history of gestational diabetes.  Early signs and symptoms of hyperglycemia that include 
polyuria, polydipsia, polyphagia, blurred vision, fatigue and headaches should also be monitored. 
Subjects who experience treatment-emergent hyperglycemia should be closely monitored and 
treatment should be based on current guidelines.  Initiation of therapy should take into 
consideration each subject’s underlying health status and the use of appropriate glycemic targets.   
The management of hyperglycemia depends on several factors including: the duration, frequency 
and severity of hyperglycemia, and the subject’s age, health, and cognitive function.  The 
American Diabetes Association (ADA) and the European Association for the Study of Diabetes 
(EASD) have updated their recommendations on the management of hyperglycemia based on

underlying risk factors including underlying cardiovascular and renal disease.  According to 
these guidelines, glycemic treatment targets should be individualized based on patient 
preferences and goals, risk of adverse effects of therapy (eg, hypoglycemia and weight gain), and 
subject characteristics, including frailty and comorbid conditions (Davies 2018).  Glycemic 
management is primarily assessed by measuring HbA1c and the choice of glucose-lowering 
medications should be accompanied by lifestyle management, weight loss, exercise, dietary 
modification, diabetes self-management education and support, and patient-centered care.   
While criteria for initiating therapy requires individualizing HbA1c targets, a reasonable HbA1c 
target is approximately ≤7% (53 mmol/mol) (Davies 2018).  The selection of the appropriate 
individualized therapy is described in current guidelines from ADA and EASD for management 
of hyperglycemia (Appendix B). 
Subjects displaying increasing fasting glucose, HBA1c, or HOMA-IR levels should be referred 
to either their treating physician, if already under care for diabetes, or to their HCP or an 
endocrinologist if they experience new onset type 2 diabetes mellitus. 
9.5. 
Treatment Compliance 
The Investigator should assess the subject’s compliance with dosing of investigational product at 
each study visit after Day 1. 
Subjects should be instructed to retain all bottles of investigational product, even if empty, and to 
return them to the Investigator at the indicated visits in Table 1 and Table 2.  The Investigator or 
designee should perform investigational product accountability (ie, count of returned tablets) 
and, if applicable, follow-up with the subject to retrieve any investigational product bottles that 
have not been returned.  
If the Investigator has concerns about a subject’s dosing compliance, he or she should discuss 
this with the subject, assess the reasons for noncompliance and the likelihood that the subject 
will remain noncompliant, and notify the Sponsor accordingly.   
9.6. 
Randomization and Blinding 
9.6.1. 
Methods of Assigning Subjects to Treatment Groups 
This study will be conducted in a double-blind, placebo-controlled manner.  Enrolled subjects 
will be randomized in a 1:1:1 ratio to one of the three treatment arms:  once daily dosing of OCA 
10 mg, OCA 10 mg → 25 mg (ie, OCA 10 mg with uptitration to OCA 25 mg at Month 3), or 
placebo.  Randomization will be done using an RTSM and will be based on a predefined 
randomization code generated by the Sponsor or designee.  Subjects randomized to OCA 
10 mg → 25 mg will initiate dosing at OCA 10 mg for 3 months prior to uptitrating to OCA 
25 mg.  Uptitration will be determined based on the laboratory criteria and safety and tolerability 
assessments completed prior to Month 3 (Section 9.2.1). 
Randomization of subjects will be stratified by the presence of type 2 diabetes at enrollment (yes 
or no).   

Protocol 747-304 
Version 7.0:  16Jun2021
 
Page 85
 
Confidential and Proprietary 
All subjects who enroll into the OLE will receive OCA.  Subjects randomized to placebo in the 
Double-Blind Phase will be re-randomized to OCA 10 mg or OCA 10 mg → 25 mg arms, with 
uptitration at OLE Month 3 in the OCA 10 mg → 25 mg arm (refer to Section 9.2) 
The RTSM will also serve as the investigational product inventory and management system.  
The Investigator or designee will be required to register the subject in the RTSM and may be 
prompted to provide patient data necessary to properly randomize and allocate the subject to 
treatment.  A randomization number will be assigned and investigational product (OCA or 
placebo) dispensing information will be provided (eg, bottle numbers allocated) while 
maintaining the study blind.   
To maintain blinding, all placebo, OCA 10 mg, and OCA 25 mg tablets and bottles will be 
identical. 
9.6.2. 
Blinding 
The subjects, Investigators, and study site staff will be blinded to the subject’s treatment regimen 
until all subject data have been collected from the study and the database is locked for Double-
Blind Phase.  Using this approach, blinding of the study will be maintained.  
9.6.3. 
Emergency Unblinding Procedures 
Randomization codes and corresponding treatment assignments will be made available to the 
Investigator for emergency use only through the RTSM system.  When possible, the Medical 
Monitor should be consulted in the event that a medical emergency necessitates unblinding 
(ie, in situations where knowledge of the unblinded treatment is necessary for further medical 
management of the subject).  If it is not reasonable to inform the Medical Monitor in advance of 
unblinding, the Investigator must promptly document the case in the subject’s source record.  
Subsequently, the Investigator should contact the Medical Monitor to explain any premature 
unblinding of treatment assignment (eg, accidental unblinding or unblinding due to a SAE).  
Procedures for unblinding a subject’s treatment will be provided separately to the Investigator.  
Similarly, if the Medical Monitor breaks the blind for the purpose of evaluating an emergent 
safety issue or for regulatory reporting purposes, the Medical Monitor will document within 
study correspondence the rationale, circumstances, and the person(s) being informed about the 
unblinding.   
The DMC (refer to Section 17.13) will have access to randomization and will be able to review 
the cases of premature unblinding.  The DMC will document details about any subject who was 
unblinded in the closed session DMC minutes, which will be made available to the Sponsor only 
after the double-blind database is locked and unblinded.  Cases of premature unblinding (as 
noted above) will be reviewed by the DMC. 
Access to randomization codes and corresponding treatment assignments will also be made 
available through the RTSM system to the appropriate, named individual(s) responsible for 
unblinding suspected unexpected serious adverse reactions (SUSARs) for reporting to the 
regulatory authorities.

Assignment of Site and Subject Numbers 
9.7.1. 
Site Numbers 
Each study site selected to participate in this study will be assigned a site number by the Sponsor.  
The site number will be used to categorize subject data and to identify the site and/or Investigator 
within study documents.  This number will be recorded in the eCRF. 
9.7.2. 
Subject Numbers 
Subjects are assigned using a unique 10-character, 9-digit identifier (AAA-BBBCCC), 
independent of the randomization number.  The first 3 digits represent the last 3 digits of the 
protocol number, followed by a hyphen (AAA-).  The next 3 digits represent the site number 
(BBB).  The last 3 digits represent a unique screening number that is assigned in sequential order 
at each site starting with 001 (CCC).  Note, in the case of incorrect data entry by a site when 
more than one subject is inadvertently created, the spurious subject numbers will be deleted and 
may not be used again; in this circumstance there may be gaps in the subject numbering scheme 
at a site. 
9.8. 
Restrictions 
No additional restrictions.  
9.9. 
Highly Effective Contraception 
Recent guidelines recommend “highly effective” contraception measures for investigational 
products with limited or no human data available on pregnancies. (HMA CTFG 2014).  Highly 
effective methods of contraception per the CTFG guidelines are those that alone or in 
combination result in a failure rate of less than 1% per year when used consistently and correctly.  
The highly effective contraception measures should be maintained during treatment and until the 
end of relevant systemic exposure.  Women of child-bearing potential, currently enrolled in the 
747-304 study, will employ the highly effective contraception measures during treatment with IP 
for their participation in the study.  
Female subjects must be postmenopausal, surgically sterile, or, if premenopausal (and not 
surgically sterile), be prepared to use at least one highly effective method of contraception during 
the study and for 30 days after the end of treatment.  
Highly effective methods of contraception include the following: 
• Intrauterine device  
• Intrauterine hormone-releasing system 
• Bilateral tubal occlusion 
• Vasectomy (male partner) 
• Combined (estrogen- and progestogen-containing) hormonal contraception (eg, oral, 
intravaginal or transdermal) associated with inhibition of ovulation.  

Protocol 747-304 
Version 7.0:  16Jun2021
 
Page 87
 
Confidential and Proprietary 
• Progestogen-only hormonal contraception (eg, oral, injectable or implantable) 
associated with inhibition of ovulation.  
• Sexual abstinence, if in line with the preferred and usual lifestyle of the subject 
(where abstinence is defined as refraining from heterosexual intercourse during the 
entire period of risk associated with study treatments). 
9.10. 
Visit Procedures 
Visits should be based on Day 1 (not on the prior visit) unless stated otherwise.  The day of the 
first dose from the OLE bottle is considered OLE Day 1.  If Day 1 occurs on January 1st, 
Month 3 should ideally occur on April 1st (±1 week).  This is the definition of a calendar month.  
The visit windows are listed in Table 1 and Table 2.  Acceptable windows for PK sampling 
timepoints are in Table 7. 
9.10.1. 
Informed Consent Procedures 
The Investigator or designee will explain the nature, purpose, possible risks, and benefit of the 
study to the subject and will provide him/her with a copy of the informed consent form (ICF).  
The subject will be given sufficient time to consider the study before deciding whether or not to 
participate.  The subject will be informed that participation is voluntary and that her/his future 
medical treatment will not be compromised by participation in the study and that he or she can 
withdraw from the study at any time.  The subject must be willing and able to provide written 
informed consent before entering the study.  The Investigator or a medically qualified designee is 
responsible for administering and documenting the written informed consent of the subject.  The 
subject will be given a copy of his/her signed and dated ICF.  Subjects will also be required to 
provide consent prior to participating in any of the optional assessments, such as providing blood 
samples for serial PK draws.  
9.10.2. 
Fasting Requirement at Study Visits 
Starting with Screening Visit 2, all subjects must arrive to the study site in a fasted state (at least 
8 hours before each visit).  Water is permitted during the fasting period.  If the subject reports 
having eaten within 8 hours of the visit, the nonfasted state will be documented in the source; 
however, scheduled assessments (blood collection) will still be performed during the visit, and 
these subjects will be reminded that fasting is required before all study visits. 
9.10.3. 
Screening Visit Procedures  
Two Screening Visit assessments must be performed to determine whether the subject meets all 
the inclusion criteria and none of the exclusion criteria.  Subjects who do not fulfill all eligibility 
criteria will not be enrolled in the study.  Subjects may be rescreened after 2 months have 
elapsed from the date of their most recent screening visit procedure, or with alternative timing 
approved by the Sponsor’s Medical Monitor; however, all Screening procedures (including 
obtaining informed consent) should be repeated and a new three-digit Screening number 
assigned. 
The 2 Screening visits must occur at least 4 weeks apart to confirm pretreatment serum 
chemistry levels, including ALT, AST, and total bilirubin.

• Screening Visit 1 will occur ≤12 weeks prior to Day 1.  
• Screening Visit 2 will occur ≥4 weeks after Screening Visit 1. 
If ALT, AST, or total bilirubin (conjugated bilirubin for subjects with an established diagnosis of 
Gilbert’s syndrome) assessments collected at Screening Visit 2 is are ≥30% higher than the 
Screening Visit 1 value(s) and >ULN, then a third measurement must be obtained at an 
unscheduled visit for eligibility determination. 
9.10.3.1. Screening Visit 1 
The Screening Visit assessments must be performed within ≤12 weeks prior to Day 1 to 
determine whether the subject meets all the inclusion criteria and none of the exclusion criteria.  
Subjects who do not fulfill all eligibility criteria will not be enrolled in the study. 
If an Investigator intends to rescreen a subject <2 months after the initial screening, this decision 
should be discussed with the Sponsor’s Medical Monitor to confirm that early rescreening will 
not affect safety or efficacy for the subject.  When rescreening, all Screening Visit procedures 
should be repeated and a new screening number assigned.  Subjects should be reconsented, as 
appropriate, at this time. 
Screening Visit 1 procedures for all subjects are as follows: 
• Review ICF and obtain signatures before performing any study-related procedures, 
including Screening procedures 
• Collect medical history  
• Assess and record any pretreatment AEs (after the ICF has been signed) 
• Record prior (if within 12 months of Day 1) and current concomitant medications 
• Verify inclusion and exclusion criteria for eligibility 
• Record vital signs (body temperature, sitting heart rate, respiratory rate, and seated 
blood pressure after sitting 3 minutes) 
• Measure height.  Record weight and BMI 
• Conduct physical exam  
• Perform standard 12-lead ECG

subjects without a recent liver biopsy with unstained slides or adequate tissue block, 
an on-study liver biopsy must be performed within the 12-week screening window 
before Day 1 (assuming all other Screening assessments indicate a likelihood that the 
subject will qualify based on biopsy).   
• Obtain blood samples for: 
− HCC screening (AFP) 
− Serum chemistry, hematology, and coagulation  
− Glucose and HbA1c

Note:  Noninvasive radiological measurements may be completed any time during 
Screening Visit 1 through Day 1 but should be conducted prior to an on-study liver 
biopsy, if one is necessary, and before initiation of investigational product on Day 1. 
• Obtain urine sample for urinalysis 
• Perform a urine-based beta human chorionic gonadotropin (β-hCG) pregnancy test for 
females of childbearing potential 
• Instruct the subject to fast overnight (at least 8 hours) before the next visit (water is 
permitted).  Fasting is required before Screening Visit 2.

Unscheduled Safety Visit 
The Investigator may schedule an at-clinic Unscheduled/Safety Visit at any time if clinically 
warranted.  Unscheduled and/or repeat assessments, including additional laboratory tests or 
investigations, may be conducted.  As appropriate, the Medical Monitor should be contacted. 
Additionally, all subjects who were unable to complete the liver biopsy at the Month 18 Visit 
due to the restrictions from the COVID-19 pandemic, regardless of whether they received 
additional supply of investigational product or not as described in Section 9.3, are to return to the 
site for an unscheduled visit to complete the liver biopsy as soon as practical following 
lifting/easing of the COVID-19 restrictions.  At this unscheduled visit, the types of 
procedures/assessments required to be performed, in addition to the liver biopsy, are the 
following: 
• If this unscheduled visit occurs more than 6 weeks since the original Month 18 Visit, 
then all Month 18 study visit procedures are to be performed, including but not 
limited to procedures that could not be performed at Month 18 due to COVID-19 
restrictions. 
• If this unscheduled visit occurs within 6 weeks since the original Month 18 Visit, then 
only the assessments that could not be obtained at the Month 18 Visit and recording 
of any AEs and concomitant medications are to be completed.   
• In addition, for any subject who wishes to enroll in the OLE phase, safety laboratory 
tests (refer to Table 2) as well as any additional assessments required to determine 
eligibility for the OLE (including EGD) are to be completed. 
10. 
STUDY MANAGEMENT DURING COVID-19 
The COVID-19 infection control measures that have been imposed by local and national 
governments to contain the COVID-19 pandemic have resulted in some study sites not being 
able to perform protocol-specified procedures and assessments such as collecting laboratory 
samples.  In addition, some subjects are unable to return to study sites for evaluations and/or to 
receive continued supply of investigational product.  Enforcement of many restrictions by local 
authorities have also affected the site monitor’s ability to perform on-site monitoring during the 
pandemic.   
This section describes the processes under which subjects who are unable or unwilling to return 
to study sites may complete protocol-specified assessments and continue to receive 
investigational product until in-person site visits can resume.  To ensure the continued safety 
monitoring of the participating subject and to minimize the potential adverse impact on 
achieving the objectives of the study due to the restrictions from the COVID-19 pandemic, the 

Protocol 747-304 
Version 7.0:  16Jun2021
 
Page 113
 
Confidential and Proprietary 
following approaches may be applied to the study protocol.  Investigators should document the 
reason for any contingency measures implemented and how restrictions related to COVID-19 led 
to the changes in study conduct, duration of those changes, and how those study participants 
were impacted. 
10.1. 
Alternative Approaches for Study Conduct Due to COVID-19  
For subjects who are unable to attend in-person study visits due to national or local restrictions, 
the following alternative options are deemed acceptable, upon required Ethic Committee or 
Regulatory Agency approval, to satisfy the requirements for continued supply of investigational 
product:   
• Subject Consent:  If re-consent is necessary alternative ways of obtaining re-consent 
should be considered, including obtaining oral consent via phone or video-call 
supplemented with e-mail confirmation.  If the technology is available, then 
electronic methods of obtaining informed consent such as DocuSign® would also be 
considered.  
• Subject Assessment:  In place of in-person visits, assessment of subjects may be 
performed using a "virtual visit" including phone consultation, or video 
(telemedicine) visits by authorized investigators to undertake examinations on the 
study.  All assessments should adhere as closely as possible to the visit windows 
specified in the protocol schedule of visits.  In case this is not possible, please discuss 
with the Medical Monitor or Sponsor. 
• Laboratory Tests:  If central laboratory testing cannot be performed at the study site 
or via homecare visits, every attempt should be made to perform the protocol-
required tests at a local laboratory.  The results and reference ranges of all laboratory 
tests are to be sent to the Investigator and entered in to the eCRF.  Note: 
Investigational product can only be dispensed if central or local laboratory values 
are available.  
− Minimum testing required to support the protocol:  
o Liver safety labs:  Direct and Total bilirubin; AST, ALT, ALP, GGT, INR, 
platelet count, sodium, albumin and creatinine.   
o Non-Liver safety labs:  CBC & Diff; standard electrolytes (sodium & 
potassium only), lipid panel, fasting blood glucose, and urine-based β-hCG 
pregnancy test. 
• Investigational Product Distribution:  Investigational product may be sent directly to 
the subject from either the study site or a third-party vendor via a courier service if 
subjects are not able to attend study site visits.  Direct shipment of investigational 
product from the Investigator site to subjects must adhere to the site’s institutional 
and pharmacy procedures and country specific requirements.  If the Investigator is 
unable to evaluate safety and tolerability and assess the benefit-risk for the individual 
subject, the subject must interrupt investigational product until the assessment can be 
completed. 

Protocol 747-304 
Version 7.0:  16Jun2021
 
Page 114
 
Confidential and Proprietary 
• Home Visits:  If laboratory tests cannot be obtained from local laboratories, qualified 
home nursing support (where available and permitted) is an accepted option that may 
be employed to supplement telemedicine interactions to enable for the collection and 
processing of blood samples for laboratory tests including PK and PD samples, if 
required, and conduct other limited assessments (eg, assessment of vital signs, 
completion of protocol required subject questionnaires).   
• Monitoring:  Cancelling or postponing of on-site monitoring visits and extension of 
the period between monitoring visits may occur per specific local guidelines and 
regulations.  Alternatively, additional off-site monitoring activities such as phone 
calls, video visits, emails may be used to discuss the trial with the Investigator and 
site staff.  Remote source verification also may be performed if it is permissible by 
the local regulations. 
Any other alternative procedures or assessments not listed above must be discussed with the 
Medical Monitor and documented by the Investigator, maintain subject participant confidentiality 
and be compliant with HIPPA/GDPR and 21 CFR Part 11 guidance. 
In addition to regularly collected trial data, available COVID-19 related data such as COVID-19 
testing will also be collected for all subjects.  Any subject that contracts the SARS-CoV-2 virus 
should have this reported as an adverse event under the description “COVID-19” per MedDRA 
23.1.  If a subject is hospitalized for COVID-19 complications an SAE should be reported in 
accordance with the protocol and national requirements.   
COVID-19 Vaccine 
COVID-19 vaccination (with vaccines approved for emergency use in the country where you 
practice) is allowable for participants enrolled in Intercept-sponsored PBC and NASH clinical 
trials.  Of note, as the currently approved COVID-19 vaccines have not been specifically tested 
in the NASH or PBC subject population, nor in the pediatric population suffering from biliary 
atresia (BA), there are no safety data available specific to the use of COVID-19 vaccines in PBC, 
NASH subjects or in children suffering from BA. 
If a subject receives a COVID-19 vaccination, the date(s) of vaccination(s), vaccine name, and 
manufacturer should be recorded as a concomitant medication for each dose.

EFFICACY ASSESSMENTS 
The assessments supporting the efficacy analyses are as follows: 
13.1. 
Liver Biopsies 
Given that historical biopsies are to be obtained no more than 12 months before Day 1, slides 
should be sent for central reading at least 4 weeks before the end of the 12-month window to 
ensure that the results are available in time for Day 1. 
Liver biopsies will generally be obtained from the right lobe of the liver as described in a 
study-specific histology manual.  Liver biopsies should be performed after the hepatobiliary 
ultrasound for HCC screening.  If the initial biopsy was obtained from the left lobe, then 
subsequent biopsies must be obtained from the left lobe.  For subjects who develop potential 
clinical outcomes or liver-related clinical outcome events during the study, their continued 
participation in the study is encouraged but biopsies scheduled after the diagnosis based on 
central reading may not be required. 
13.1.1. 
Central Reading of Liver Histology 
Full instructions concerning the number and type of samples to be collected at each visit, the 
sample collection methods, sample processing, labeling, and shipping will be provided by the 
Sponsor in a study-specific histology manual.  All necessary collection supplies will be provided 
by the central laboratory and will be appropriately assembled for the specific evaluations 
required at each visit. 
All biopsy assessments will be performed centrally, including assessments of biopsies to 
determine study eligibility.  Histological presence of NASH with a fibrosis score of 4 based on 
the NASH CRN scoring system must be confirmed for study eligibility.  For each biopsy, 
fibrosis will be graded in accordance with the NASH CRN scoring system (Table 6) 
(Kleiner 2005).

CP score will be calculated as described in Section 7.4.3.1 and according to the frequency listed 
in Table 1 (Double-Blind Phase) and Table 2 (OLE Phase). 
13.3. 
MELD Score 
MELD score will be calculated as described in Section 7.4.3.2 and according to the frequency 
listed in Table 1 (Double-Blind Phase) and Table 2 (OLE Phase). 
13.4. 
Prospective Surveillance 
HCC screening will include a hepatobiliary ultrasound and AFP assessment according to the 
schedule presented in Table 1 (Double-Blind Phase) and Table 2 (OLE Phase). 
For subjects who develop HCC during the study, HCC screening assessments for study visits 
after onset of HCC are not required.  
13.5. 
Patient-Reported Outcomes and Healthcare Resource Use 
Data will be collected to determine the effects of OCA on health-related quality of life.  
Healthcare resource use as well as a general health status assessment (for the purposes of 
generating health utilities) will be used to support subsequent cost-effectiveness analyses that are 
relevant to major health care systems around the world.  Assessments of patient-reported 
outcomes will take place during the visits indicated in Table 1. 
The following patient-reported outcomes will be used to evaluate the effects of OCA compared 
to placebo on improvements in health-related quality of life:

• Chronic Liver Disease Questionnaire (CLDQ-NAFLD):  The CLDQ-NAFLD is a 
modified version of the general CLDQ (Younossi 1999).  The CLDQ-NAFLD is a 
36-item validated instrument designed to measure health-related quality of life in 
patients with liver disease (Younossi 2016).  The CLDQ-NAFLD is organized into 
6 domains:  abdominal symptoms, systemic symptoms, fatigue, activity, emotional 
function, and worry.  Each question is answered on a scale from 1 (always) to 
7 (never).  Therefore, a higher score corresponds to a better quality of life while 
conversely a lower score corresponds to a worse quality of life. 
• EQ-5D-5L:  The EQ-5D-5L consists of 2 sections – the descriptive system and the 
visual analog scales (VASs).  The descriptive system is organized into 5 dimensions:  
mobility, self-care, usual activities, pain/discomfort, and anxiety/depression.  Each 
dimension has 5 levels:  no problems, slight problems, moderate problems, severe 
problems, and extreme problems.  The VAS records the subject’s self-rated health on 
a 20-cm vertical, line with endpoints labelled “the best health you can imagine” and 
“the worst health you can imagine” (Herdman 2011, Oemar 2013). 
• Work Productivity and Activity Index (WPAI):  The WPAI is a validated instrument 
designed to measure impairment in work and activities.  The WPAI is organized into 
4 domains:  absenteeism, presenteesism, work productivity loss, and activity 
impairment.  WPAI outcomes are expressed as impairment percentages, with higher 
numbers indicating greater impairment and less productivity (Prasad 2004). 
Subjects will be asked to complete the questionnaires and initial and date each document.  The 
questionnaires should be filed in the subject’s study records.   
13.6. 
Noninvasive Assessments of Liver Disease 
13.6.1. 
Noninvasive Scores of Liver Fibrosis  
Noninvasive scores of liver fibrosis (NFS, FIB-4, and APRI) will be calculated according to the 
schedule presented in Table 1 (Double-Blind Phase). 
13.6.2. 
Noninvasive Panel of Liver Fibrosis Markers 
FibroMeter (Echosens, Paris, France) combines multiple values including Fibroscan TE liver 
stiffness, age, gender, weight, and blood-based biomarkers (platelets, alpha-2-macroglobulin, 
ALT, urea, GGT, AST, ferritin, glucose level, and prothrombin ratio) to quantify liver fibrosis.  
The test can be conducted by staff who are trained in the use and data interpretation of the 
diagnostic test. 
ELF (Siemens Healthcare, Tarrytown, New York, USA) combines 3 serum markers (HA, P3NP, 
and TIMP-1) to quantify liver fibrosis.  The test can be performed by staff who are trained in the 
use and data interpretation of the diagnostic test. 
Noninvasive panel of liver assessments will be performed according to the schedule presented in 
Table 1 (Double-Blind Phase).

Noninvasive Radiological Liver Fibrosis Measurements 
At investigational sites where the device is available, TE using the Fibroscan instrument 
(Echosens, Paris, France) and MRE, to assess liver fibrosis will be conducted by staff who are 
trained in the use and data interpretation of the device.  Assessments will be performed according 
to the schedule presented in Table 1 during the Double-Blind Phase only.  MRE will be assessed 
only in subjects enrolled prior to Version 5 of the protocol who had a baseline MRE already 
performed, not in newly enrolled subjects. 
13.7. 
Efficacy Laboratory Assessments 
Refer to Table 13 for a full list of analytes to be tested.  Laboratory assessments will be 
performed according to the schedule presented in Table 1 (Double-Blind Phase) Table 2 (OLE 
Phase). 
HOMA-β and HOMA-IR values will be calculated based on glucose and insulin concentrations. 
Laboratory analyte results may be used to calculate various cardiovascular risk and fibrosis 
measurement scores. 
14. 
CLINICAL PHARMACOLOGY ASSESSMENTS 
Subjects who receive at least one dose of OCA and have measurable plasma PK concentration 
data available will be included in the PK analysis. 
A PK blood sample should be collected in subjects who experience an SAE during the study.  
Blood samples should be collected as soon as possible after the SAE is identified but no later 
than 7 days after the onset of the SAE.  The times of the last dose of investigational product, the 
last meal, and the PK sample collection should be recorded. If a PK sample cannot be collected 
within 7 days, the reason should be recorded in the eCRF. 
14.1. 
Pharmacokinetic Blood Sampling 
Subjects may opt to provide blood samples for serial PK assessments.   
Subjects participating in serial PK assessments will provide blood samples for measurement of 
OCA and its conjugates (glyco-OCA and tauro-OCA) at 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 5, and 
6 hours post-dose on Month 1, Month 4, Month 12, and Month 18. 
Subjects should be reminded to fast for at least 8 hours prior to the PK assessment; although 
water is allowed during the fasting period.  If the subject reports having eaten within the fasting 
period, this will be documented in the source and the eCRF; however, the PK assessment will 
still be conducted. 
Subjects will then receive a dose of investigational product with approximately 240 mL of water.  
Subjects should not drink additional water for 1 hour after taking the dose of investigational 
product and will remain fasted until after the 1-hour sample is collected.  A meal will be 
provided following collection of the 1-hour PK sample; the meal will be a meal replacement 
drink with nutrition information that has been submitted to and approved by the Sponsor in 
advance.  No other food or drink (water is permitted) will be allowed until after the 6-hour 
sample collection.

collection of blood samples (including further processing into plasma), storage, and shipment 
procedures for subsequent bioanalysis will be provided to the investigational site in a separate 
document before the study is initiated. 
14.3. 
Bioanalysis 
Plasma concentrations of OCA and its conjugates (glyco-OCA and tauro-OCA) will be 
determined using a GLP validated liquid-chromatography-mass spectrometry/ mass spectrometry 
method.  A detailed description of validation information and results from the bioanalytical assay 
will be provided in separate reports.  These samples may be used for evaluation of metabolites of 
OCA, for further evaluation of the bioanalytical method, and for analyses that provide 
information on the metabolic pathways used or impacted by OCA.  These data would only be 
used for exploratory purposes and may not be included in the clinical study report. 
Total OCA will be calculated based on OCA, tauro-OCA, and glyco-OCA concentrations.

Adverse Events and Serious Adverse Events 
16.1.1. 
Definitions of Adverse Events 
16.1.1.1. Adverse Event  
AEs are defined as any untoward medical occurrence associated with the use of the 
investigational product in humans, whether or not considered related to investigational product.  
An AE (also referred to an adverse experience) can be any unfavorable and unintended sign 
(eg, an abnormal laboratory finding), symptom, or disease temporally associated with any use of 
the investigational product, without any judgment about causality and irrespective of route of 
administration, formulation, or dose, including an overdose. 
AEs include, but are not limited to:  (1) a worsening or change in nature, severity, or frequency 
of condition(s) present at the start of the study; (2) subject deterioration due to primary illness; 
(3) intercurrent illness; and (4) drug interaction.  For reporting purposes, pregnancy is not 
considered an AE. 
Subjects should be questioned in a general way, without leading the subject or asking about the 
occurrence of any specific symptom.  The Investigator should attempt to establish a diagnosis of 
the event based on signs, symptoms, and/or other clinical information.  The diagnosis and not the 
individual signs/symptoms should be documented as the AE.  For example, if the underlying 
disease process is a stroke, it would not be appropriate to record the AE by describing the 
symptoms “sudden numbness, dizziness, and difficulty speaking.”  The AE medical term of 
“stroke or cerebrovascular accident” should be recorded as it more accurately describes the AE. 
Subjects should be instructed to contact the site promptly upon awareness if they develop signs 
and symptoms of potential hepatic decompensation such as:  pale-colored stools, urine color 
from pale to deep amber [dark], nausea, vomiting, abdominal pain, diarrhea, weight loss, fever 
and chills, fatigue, weakness, loss of appetite, confusion, swelling of the legs or abdomen, 
yellowing of the skin or whites of eyes, and bruising easily.

16.1.1.2. Treatment-Emergent Adverse Event 
A TEAE is any event not present before the initiation of the investigational product or any event 
already present that worsens in either intensity or frequency following exposure to the 
investigational product. 
16.1.1.3. Serious Adverse Event 
An AE is considered “serious” if, in the view of either the Investigator or Sponsor, it results in 
any of the following outcomes: 
• Death 
• Is life threatening 
• Requires in-patient hospitalization or prolongation of existing hospitalization 
• Results in persistent or significant disability or incapacity 
• Results in a congenital abnormality or birth defect 
• Is an important medical event that may jeopardize the subject or may require medical 
intervention to prevent one of the outcomes listed above 
Events not considered to be SAEs are hospitalizations for: 
• Routine monitoring of the studied indication and not associated with any deterioration 
in condition or AE; 
• Elective treatment for a pre-existing condition that did not worsen; 
• Respite care or observation when there is no AE associated with the hospitalization. 
A PK blood sample should be collected in subjects who experience an SAE during the study.  
Blood samples should be collected as soon as possible after the SAE is identified but no later 
than 7 days after the onset of the SAE.  The times of the last dose of investigational product, the 
last meal, and the PK sample collection should be recorded.  If a PK sample cannot be collected 
within 7 days, the reason should be recorded in the eCRF. 
16.1.2. 
Suspected Unexpected Serious Adverse Reaction 
A SUSAR is defined as a suspected adverse reaction that is assessed as serious, causally related 
to the investigational medicinal product, and unexpected per the reference safety information 
(RSI) in the Investigator’s Brochure.  
SUSARs are subject to expedited reporting.  The Sponsor shall ensure that all relevant 
information about SUSARs that are fatal or life-threatening are recorded and reported as soon as 
possible to the relevant competent authorities (either directly or through the Eudravigilance 
Clinical Trials Module, as applicable), and to the Ethics Committees, no later than 7 days after 
knowledge by the Sponsor of such a case.  Relevant follow-up information is subsequently 
communicated within an additional 8 days.  All other SUSARs shall be reported to the competent 
authorities concerned (either directly or through the Eudravigilance Clinical Trials Module) and 
to the Ethics Committees concerned, within a maximum of 15 days of first knowledge by the 
Sponsor.  Each competent authority shall ensure that all SUSARs to an investigational medicinal

product that are brought to its attention are recorded.  The Sponsor shall also inform all 
participating Investigators, as applicable to the local regulations. 
16.1.3. 
Relationship to Investigational Product 
The Investigator will document her/his opinion of the relationship of the AE to treatment with 
the investigational product using the criteria outlined in Table 8.  An AE for which there is a 
“reasonable possibility” that the investigational product caused the AE is otherwise referred to as 
suspected adverse reaction (SAR).  “Reasonable possibility” means there is evidence to suggest a 
causal relationship between the investigational product and the AE. 
If the relationship between the AE/SAE and the investigational product is determined to be 
“definite,” “probable,” or “possible” the event will be considered to be related to the 
investigational product for the purposes of expedited regulatory reporting. 
Table 8: 
Relationship of Adverse Events to Investigational Product 
Relationship 
Description 
Definite 
A reaction that follows a reasonable temporal sequence from administration of the 
investigational product or in which the investigational product level has been established in 
body fluids or tissue; that follows a known or expected response pattern to the suspected 
investigational product; and that is confirmed by improvement on stopping or reducing the 
dosage of the investigational product, and reappearance of the reaction on repeated 
exposure. 
Probable 
A reaction that follows a reasonable temporal sequence from administration of the 
investigational product; that follows a known or expected response pattern to the suspected 
investigational product; that is confirmed by stopping or reducing the dosage of the 
investigational product; and that could not be reasonably explained by the known 
characteristics of the subject’s clinical state. 
Possible 
A reaction that follows a reasonable temporal sequence from administration of the 
investigational product; that follows a known or expected response pattern to the suspected 
investigational product; but that could readily be produced by a number of other factors. 
Unlikely 
An event that does not follow a reasonable temporal sequence from administration of the 
investigational product; that does not follow a known or suspected response pattern to the 
suspected investigational product; and that could reasonably be explained by known 
characteristics of the subject’s clinical state. 
Not Related 
Any event that does not meet the above criteria. 
16.1.4. 
Relationship to Liver Biopsy 
The Investigator will document her/his opinion of the relationship of the AE to liver biopsy using 
the criteria outlined in Table 9.

16.1.6. 
Recording Adverse Event Severity 
AEs must be graded for severity (ie, intensity) using the current version of the CTCAE 
(Appendix D).  A severity category of mild, moderate, severe, life threatening, or death as 
defined in Table 11, must be entered on the AE eCRF. 
Because a grading (severity) scale is provided for each AE term and not all grades are 
appropriate for all AEs, it may be necessary to refer to (Appendix D) before grading the severity 
of an event. 
It should be noted that the term “severe” used to grade intensity is not synonymous with the term 
“serious.”  The assessment of severity is made regardless of investigational product relationship 
or of the seriousness of the AE.  When reporting AEs, reference should be made to the CTCAE 
manual for guidance on appropriate grading. 
Table 11: 
Severity of Adverse Events 
Grade 
Clinical Description of Severity 
1 = Mild 
Asymptomatic or mild symptoms, clinical or diagnostic observations only, or 
intervention not indicated.  
2 = Moderate 
Minimal, local or noninvasive intervention indicated; or limiting age-appropriate 
instrumental activities of daily living.a 
3 = Severe 
Medically significant but not immediately life-threatening, hospitalization or 
prolongation of hospitalization indicated, disabling, or limiting self-care activities of 
daily living.b 
4 = Life-threatening 
Urgent intervention indicated. 
5 = Death 
Death related to AE. 
a Instrumental activities of daily living refer to preparing meals, shopping for groceries or clothes, using the 
telephone, managing money, etc. 
b Self-care activities of daily living refer to bathing, dressing and undressing, feeding self, using the toilet, taking 
medications, and not bedridden.

16.1.6.1. Severity of Pruritus (as an Adverse Event) 
To ensure consistency in reporting, pruritus AEs must be graded for severity (ie, intensity) using 
the current version of the CTCAE (Appendix D).  As pruritus is a subjective symptom, clinical 
judgment should be used to determine its severity and management Table 12.  
Table 12: 
Severity of Pruritus 
Pruritus 
Grade 
Clinical Description of Severity for Pruritus and Medical Intervention 
1 = Mild 
Mild or localized; topical intervention indicated. 
2 = Moderate 
Intense or widespread; intermittent; skin changes from scratching (eg, edema, 
papulation, excoriations, lichenification, oozing/crusts); oral intervention indicated; 
limiting instrumental activities of daily living. 
3 = Severe 
Intense or widespread; constant; limiting self-care activities of daily living or sleep; oral 
corticosteroid or immunosuppressive therapy indicated. 
Since pruritus is a subjective symptom and the occurrence and magnitude of which are not 
readily measured by objective tools, clinical judgment needs to be applied in the management of 
each subject.  Managing OCA-related pruritus may help improve tolerance in those subjects who 
experience problematic pruritus and may otherwise discontinue from the study prematurely.  
General guidance for the management of subjects experiencing significant pruritus includes: 
• Drug holiday:  A drug holiday is defined as an Investigator ‘prescribed’ complete 
interruption of dosing for 1 or more consecutive days (ie, non-daily dosing does not 
constitute a drug holiday).  Details of drug holidays and/or nondaily dosing regimens 
should be recorded in the eCRF.  Per Section 7.7, subjects with pruritus ≥Grade 3 in 
severity (per CTCAE) must discontinue investigational product but are encouraged to 
continue study visits. 
• Short-term use of BAS  
− Use of BAS may be considered in conjunction with a change in investigational 
product dosing frequency (ie, every other day dosing) for approximately 2 weeks.  
The subject should be evaluated after the 2-week intervention to assess the status 
of pruritus and stop the use of BAS as deemed appropriate by the Investigator.  If 
the Investigator considers that the subject can tolerate investigational product, 
daily dosing may be reinitiated.  
− If the subject cannot tolerate investigational product after stopping BAS due to 
ongoing pruritus, the Investigator should consult with the Medical Monitor to 
determine a treatment plan.  This may include continuing every other day dosing, 
interrupting or discontinuing investigational product.   
− If after 4 to 6 weeks (or up to 3 courses of a 2-week BAS therapy), the subject is 
unable to tolerate investigational product without BAS treatment, the Investigator 
should consider, in consultation with the Medical Monitor, discontinuing 
investigational product.   

Protocol 747-304 
Version 7.0:  16Jun2021
 
Page 130
 
Confidential and Proprietary 
− The subject should make every effort to avoid long-term use of BAS for pruritus 
while taking investigational product.  For additional guidance on BAS refer to 
Section 9.4.3 
• Other medical therapies for the management of pruritus may be considered as deemed 
clinically appropriate and based on current practice guidelines (EASL 2017) or 
literature (Hegade 2015). 
• Less frequent dosing of investigational product (eg, on alternate days) may be tried, 
after which subjects may return to their original daily dose as soon as tolerated. 
16.1.7. 
Reporting of Adverse Events and Serious Adverse Events 
16.1.7.1. Reporting of Adverse Events 
AE data will be collected from the time that signed informed consent is obtained until the subject 
fully completes her/his study participation of the study. 
All AEs, whether believed by the Investigator to be related or unrelated to the investigational 
product, must be documented in the subject’s medical records, in accordance with the 
Investigator’s normal clinical practice and on the AE eCRF.  Each AE is to be evaluated for 
duration, intensity, frequency, seriousness, outcome, other actions taken, and relationship to the 
investigational product. 
In addition, the Investigator should contact the study Medical Monitor upon awareness when any 
signs or symptoms of hepatic decompensation are observed in any subject. 
Redacted medical record source documentation will be requested for all SAEs.  
16.1.7.2. Reporting of Serious Adverse Events 
In agreeing to the provisions of this protocol, the Investigator accepts all legal responsibilities for 
immediate reporting of SAEs to the Sponsor.  Immediate reporting implies within 24 hours of 
becoming aware of the occurrence of an SAE. 
All SAEs (including potential liver-related clinical outcome events that qualify as serious) must 
be reported to the Sponsor.  SAEs are reported by entering the SAE data into the study specific 
electronic data capture (EDC) system.  Entering the SAE data into the EDC system will 
automatically notify the Sponsor of the event.  In the event that the EDC system is inaccessible, 
an SAE may reported by: 
If an SAE is reported by telephone or fax, an SAE Report form must also be completed in the 
EDC system as soon as the EDC system is accessible.  At a minimum, the following information 
should be provided at the time of the initial report: 
• Subject number 
• Event term 
• At least 1 criterion classifying the event as serious 

Protocol 747-304 
Version 7.0:  16Jun2021
 
Page 131
 
Confidential and Proprietary 
• Name and title of the reporting individual 
• Causal relationship to the investigational product 
The Investigator will assess whether the event is causally related to the investigational product.  
The Sponsor will also assess whether the event is causally related to the investigational product, 
in addition to assessing the overall safety profile of the investigational product.  The Sponsor will 
notify the appropriate regulatory agencies as well as all participating Investigators of 
investigational new drug (IND) Safety Reports/Expedited Safety Reports that occur during the 
study within the time frames required by each regulatory agency. 
Following the initial report, any additional information obtained by the Investigator about the 
SAE must be reported promptly to the Sponsor in the same manner as described above for the 
initial SAE report.  Any supporting source documentation should be
s soon as possible. 
The Investigator is responsible for submitting information on IND Safety Reports/Expedited 
Safety Reports received from the Sponsor to her/his local IRB/IEC, as directed by the 
local-country requirements. 
Documentation of the submissions to IECs/IRBs must be retained in the appropriate study file(s).  
As instructed by the Sponsor, IND Safety Reports/Expedited Safety Reports should be retained 
in the appropriate investigative site study files, or with the IB. 
16.1.8. 
Potential Liver-Related Clinical Outcome Events 
Specified liver-related clinical outcome events may, by definition, qualify as SAEs (see 
Section 16.1.1.3).  The Sponsor must be notified of any SAEs within 24 hours of the site 
becoming aware of the event (see Section 16.1.7.2).  The Sponsor is responsible for regulatory 
reporting of SAEs, including expeditious reporting of SUSARs, refer to Section 16.1.2 for 
definition of SUSAR. 
16.1.9. 
Additional Investigator Responsibilities for SAEs 
The safety data recorded in the EDC represent the official record of all AEs and SAEs reported 
in the study.  The Investigator should comply with requests by the Medical Monitor or other 
Sponsor personnel to record the SAE on the subject’s AE eCRF.  Other supporting documents 
such as radiology reports, hospital discharge summaries, and autopsy reports should also be 
provided, when appropriate.  Additionally, upon request by the Sponsor, the Investigator should 
provide input into the SAE narrative and provide timely information to ensure prompt follow-up 
and closure of the SAE report. 
The Investigator and supporting personnel responsible for subject care should discuss with the 
Medical Monitor any need for supplemental investigations of SAEs.  The results of these 
additional assessments must be reported to the Medical Monitor. 
16.1.10. 
Notification of Post-Treatment SAEs for Subjects Who Continue in the Study 
Post-treatment SAEs that occur in subjects who remain in the study after investigational product 
has been discontinued must be reported to the Sponsor within 24 hours by following the 
instructions provided in Section 16.1.7.2. 

Protocol 747-304 
Version 7.0:  16Jun2021
 
Page 132
 
Confidential and Proprietary 
16.1.11. 
Notification of Post-Study SAEs 
All SAEs that occur within 30 days following discontinuation from the study, whether or not 
they are related to the investigational product, must be reported to the Sponsor within 24 hours 
by following the instructions provided in Section 16.1.7. 
If an Investigator becomes aware of an SAE that may be attributable to the investigational 
product at any time after the end of the study, the Sponsor should be notified immediately 
(ie, within 24 hours) by following the instructions provided in Section 16.1.7. 
16.1.12. 
Follow-Up of AEs and SAEs 
All AEs must be followed during the course of the study until the AE resolves, is no longer of 
clinical concern, has stabilized or is otherwise explained, or the subject is lost to follow-up. 
AEs ongoing at the final visit that are deemed to be ‘possibly, probably, or definitely” related or 
of other clinical significance must be followed for as long as necessary to adequately evaluate 
the safety of the subject or until the event stabilizes, resolves, or is no longer of clinical concern.  
If resolved, a resolution date for the AE should be documented on the eCRF.  The Investigator 
must ensure that follow-up includes any supplemental investigations indicated to elucidate the 
nature and/or causality of the AE.  This may include additional laboratory tests or investigations, 
or consultation with other healthcare professionals, as considered clinically appropriate by the 
Investigator. 
All subjects showing possible drug-induced liver injury or disease progression should be 
followed until all abnormalities return to normal or to the baseline state.  Drug-induced liver 
injury may develop or progress even after the causative drug has been stopped.  Results should 
be recorded in the eCRF.  Note that longer follow-up can sometimes reveal an off-drug repetition 
of what had appeared to be drug-induced liver injury, indicating that liver injury was related to 
underlying liver disease. 
If a subject experiences symptoms consistent with symptomatic cholelithiasis and/or 
complications related to gallstone disease or pancreatitis, the subject should have investigational 
product interrupted while undergoing a complete evaluation for both conditions consistent with 
local standards of care.  If symptomatic cholelithiasis and/or cholecystitis is diagnosed, the 
subject should be managed and monitored as described in Section 7.5.1.   
If a subject is suspected to have acute pancreatitis or develops signs and symptoms consistent 
with acute pancreatitis, amylase and lipase levels should be monitored for 3 months after the 
onset of symptoms per local standard of care.  If treatment-emergent acute, or nonacute 
pancreatitis is diagnosed, investigational product must be discontinued, and the subject should be 
managed and monitored as described in Section 7.5.2.  The Investigator should contact the 
Medical Monitor upon awareness of pancreatitis.  Results should be recorded promptly in the 
eCRF.

Pregnancy and Follow-Up  
Pregnancies are not considered AEs in and of themselves; however, if a female study participant 
becomes pregnant while she is enrolled in the clinical study, she must interrupt treatment with 
investigational product immediately (Section 8.2.1.4) and the Sponsor must be notified within 
24 hours of the Investigator’s awareness of the pregnancy by completing the pregnancy eCRF in 
the EDC system and downloading and completing the Pregnancy Report Form.  Any rechallenge 
of the investigational product should be implemented per the criteria outlined in Table 5. 
The pregnancy Report Form must be emailed to sae@interceptpharma.com or faxed to 
1-800-497-8521. 
In the situation that the EDC is not functioning, the Medical Monitor should be notified by 
telephone.  The investigator remains responsible for entering the pregnancy information into the 
EDC when the EDC becomes functional. 
The subject and neonate must be followed for outcome information and/or as considered 
appropriate by the Investigator and the Sponsor.  The investigator should notify the Sponsor of 
the outcome of the pregnancy by completing Pregnancy Follow-up section in the EDC.  In the 
situation that the EDC is no longer available due to study closure, the outcome of the pregnancy 
should be added to the pregnancy resolution section of the downloaded Pregnancy Outcome 
Form and faxed or emailed to the Sponsor.  Thereafter, the subject and infant must be followed 
as considered appropriate by the Investigator and any new updates should be sent to the Sponsor. 
Completing the pregnancy report form in the EDC is not a substitute for reporting an AE/SAE 
when an AE/SAE has occurred.  In the situation when an AE/SAE has occurred, the AE/SAE 
reporting procedures described in Section 16.1.7 must also be followed. 
16.2. 
Other Safety Parameters 
16.2.1. 
Medical History/Demographics 
A complete medical history will be obtained from the subject at Screening.  Smoking and alcohol 
consumption history and current habits will be recorded.  Demographic characteristics (age, sex, 
race, and ethnicity) will be recorded.  Baseline pruritus by severity will be obtained on Day 1 
using the Pruritus VAS questionnaire. 
16.2.2. 
Physical Examination 
To assess for clinical findings, the Investigator or designee will perform a physical examination 
at the visits specified in the Schedule of Study Procedures, Table 1 (Double-Blind Phase) and 
Table 2 (OLE Phase).  A basic physical examination should be performed, including all body 
systems pertinent to the subject.  Any clinically significant abnormality should be reported on the 
AE eCRF page. 
The physical examination must include the following:  
• General appearance 
• Skin 
• Head, eyes, ears, nose, and throat

Vital Signs 
Vital signs will be assessed at the visits as specified in Table 1 (Double-Blind Phase) and Table 2 
(OLE Phase): temperature, sitting heart rate, respiratory rate, and seated blood pressure after 
sitting 3 minutes.  When taking heart rate, respiratory rate and blood pressure readings, subjects 
should be seated quietly for a minimum of 3 minutes before the readings are taken. 
16.2.4. 
Electrocardiogram  
Standard 12-lead ECGs will be collected as specified in Table 1 (Double-Blind Phase) and 
Table 2 (OLE Phase). 
All ECGs should be performed before blood draws.  12-lead ECG results will be reviewed by the 
Investigator or designee and findings will be recorded in the eCRF as normal, abnormal but not 
clinically significant, or abnormal and clinically significant.  Any clinically significant 
abnormality on ECGs should be reported on the AE eCRF page. 
Investigative sites must retain a copy of all 12-lead ECGs.  These ECGs must be clearly labeled 
with the Subject ID number, date, and time.  Full instructions will be provided for forwarding the 
12-lead ECGs for central reading. 
16.2.5. 
Alcohol Consumption, Smoking Habits, and Caffeine Consumption 
Information about the subject’s alcohol consumption, smoking habits, and caffeine consumption 
will be collected during the visits indicated in Table 1 (Double-Blind Phase) and Table 2 
(OLE Phase) using the AUDIT, smoking habits, and caffeine consumption eCRFs.  AUDIT is a 
10-item questionnaire that uses the domains of alcohol consumption, drinking behavior, and 
alcohol-related problems (Saunders 1993). 
16.2.6. 
Cardiovascular Risk Scores 
Cardiovascular risk scores (10-year ASCVD Risk, FRS, Reynolds score, and SCORE) will be 
calculated according to Table 1 (Double-Blind Phase) and Table 2 (OLE Phase).

16.2.7. 
Laboratory Assessments 
Except for Screening, subjects will be instructed to attend each study visit in a fasted state, 
preferably in the morning, and subjects should remain fasted until their blood samples have been 
collected.  For visits that require fasting, the Investigator or designee will verify that the subject 
has fasted for at least 8 hours and record fasting status in the source and eCRF.  If the subject 
reports having eaten (water is permitted) within 8 hours, the Investigator or designee will 
document accordingly in the source and eCRF and remind the subject that fasting is required 
before all study visits. 
Blood and urine samples for laboratory assessments will be collected at the visits specified in 
Table 1 (Double-Blind Phase) and Table 2 (OLE Phase).  Full instructions concerning the 
number and type of samples to be collected at each visit, the required sample volumes, sample 
collection methods, sample processing, labeling, and shipping will be provided in a separate 
procedural manual.  All necessary collection supplies will be provided by the central laboratory 
and will be appropriately assembled for the specific evaluations required at each visit. 
If a subject cannot return to the clinic for a scheduled or unscheduled visit, or there is an event 
that triggers a need for an immediate assessment, the use of a local laboratory is required.  In 
these cases, the Investigator will obtain the laboratory results and the laboratory normal ranges.  
All local laboratory data, including the reference ranges, are to be collected and entered in the 
eCRF within 2 days of receiving the results.  For guidance on alternative processes under which 
subjects may complete the protocol-specified assessments under COVID-19 restrictions refer to 
Section 10. 
All subjects with laboratory tests containing clinically significant abnormal values are to be 
followed regularly until the values return to normal ranges; until a valid reason, other than 
investigational product related AE, is identified; or until further follow-up is deemed medically 
unnecessary.   
The Investigator should proactively monitor and manage lipid levels in all subjects as indicated 
via appropriate medical interventions (eg, statins).  Recent guidelines stress the importance of 
evaluating ASCVD risk in all subjects to help guide decisions in recommending therapies and 
reducing LDLc to reduce the risk and prevent onset or recurrence of ASCVD (refer to 
Section 9.4.5 and Appendix A. 
Urine based β-hCG pregnancy tests will be performed in female subjects of childbearing 
potential per protocol specified visits (Table 1) [Double-Blind Phase] and Table 2 [OLE Phase]).  
If a urine pregnancy test is positive, a serum pregnancy test must be performed to confirm the 
result.  If positive, the Sponsor must be notified and the subject will be followed as outlined in 
Section 16.1.13 until pregnancy outcome. 
An assessment of steady-state exposures (on an aggregate level) will be performed by an internal 
Intercept clinical pharmacologist/pharmacometrician or designee who is discrete from the study 
team.  These results may be made available to the DMC as appropriate (see Section 17.13).

17.2. 
Determination of Sample Size 
A sample size of 300 subjects per group will provide at least 90% power to detect a statistically 
significant treatment difference of 10% between OCA 25 mg and placebo groups based on a 
Chi-square test with 2-sided type I error at 0.05 level, assuming a responder rate of 10% in the 
placebo group.  As there was no previous study performed using the same endpoint in this 
disease, the assumption was determined based on data from literature, and results from the 
FLINT study and Study 747-303. 
17.3. 
Primary Efficacy Analysis 
The primary efficacy analysis will be conducted using the ITT population and test the following 
hypotheses: 
• H01:  The percentage of subjects with fibrosis improvement by at least 1 stage and no 
worsening of NASH defined as no increase in hepatocellular ballooning or lobular 
inflammation using the NASH CRN scoring system, from Baseline to the end of the 
Double-Blind Phase is equal between placebo and OCA 10 to 25 mg titration. 
• H11:  The percentage of subjects with fibrosis improvement by at least 1 stage and no 
worsening of NASH defined as no increase in hepatocellular ballooning or lobular 
inflammation using the NASH CRN scoring system, from Baseline to the end of the 
Double-Blind Phase is different between placebo and OCA 10 to 25 mg titration.  
• H02:  The percentage of subjects with fibrosis improvement by at least 1 stage and no 
worsening of NASH defined as no increase in hepatocellular ballooning or lobular 
inflammation using the NASH CRN scoring system, from Baseline to the end of the 
Double-Blind Phase is equal between placebo and OCA 10 mg. 
• H12:  The percentage of subjects with fibrosis improvement by at least 1 stage and no 
worsening of NASH defined as no increase in hepatocellular ballooning or lobular 
inflammation using the NASH CRN scoring system, from Baseline to the end of the 
Double-Blind Phase is different between placebo and OCA 10 mg. 
The overall type I error for primary efficacy analysis will be controlled at 0.05.  The primary 
analysis between placebo and OCA 10 to 25 mg titration will be tested first at 5% alpha and the 
hypothesis (H02) between placebo and OCA 10 mg will be tested if the null hypothesis (H01) 
between placebo and OCA 10 to 25 mg titration is rejected at 5% level.

For the comparison of the primary efficacy endpoint, a Cochran-Mantel-Haenszel (CMH) test 
stratified by the randomization strata (presence of type 2 diabetes at enrollment [yes/no] will be 
performed.  Additional details regarding analyses with missing values will be provided in the 
SAP.  
Analyses of the primary endpoint will be conducted using the mITT and PP populations and a 
sensitivity analysis will be conducted in the Month 18 biopsy-only population. 
17.4. 
Secondary Efficacy Analyses 
Secondary efficacy analyses will be conducted using mITT and PP populations. 
17.4.1. 
Histology Endpoints 
The following secondary efficacy endpoints will be analyzed: 
• Percentage of subjects with resolution of NASH defined as overall histopathological 
interpretation of 1) “no fatty liver disease” or 2) “fatty liver disease (simple or 
isolated steatosis) without steatohepatitis” as characterized/quantified by a NAS of 0 
for ballooning and 0-1 for inflammation, using the NASH CRN scoring system, at the 
end of the Double-Blind Phase 
• Percentage of subjects with resolution of NASH based on pathologist’s overall 
histopathologic interpretation of the presence or absence of definite NASH at the end 
of the Double-Blind Phase 
• Histological changes in fibrosis status including: (1) improvement, or (2) no change, 
from Baseline to the end of the Double-Blind Phase using the NASH CRN scoring 
system 
Responder endpoints will be analyzed using a CMH test stratified by the randomization strata 
(presence of type 2 diabetes at enrollment [yes/no]).   
Overall shift and frequency tables will be presented for NAS components and fibrosis scores 
(according to NASH CRN criteria). 
17.4.2. 
Clinical Outcomes 
Analyses of the clinical outcomes composite endpoint and occurrence of HCC will evaluate the 
effect of OCA (10 mg and 25 mg) compared to placebo.  Treatment groups will be compared on 
the percentage of subjects who reported any of the following adjudicated events, as well as the 
time to first occurrence:   
• Death (all cause) 
• MELD score ≥15 
• Liver transplant 
• Worsening of CP score by at least 2 points 
• Hospitalization (as defined by a stay of ≥24 hours) for onset of: 
o Variceal bleed

o Hepatic encephalopathy (as defined by a West Haven score of ≥2) 
o Spontaneous bacterial peritonitis (confirmed by diagnostic paracentesis) 
• Ascites secondary to cirrhosis and requiring medical intervention (eg, diuretics or 
paracentesis) 
• HCC (as confirmed by 2 complementary imaging modalities unless already 
confirmed by biopsy) will be analyzed as a separate outcome event.   
Only adjudicated events will be included in analyses.  Subjects with none of these events will be 
censored at the date of last contact.  For the analysis of time to first occurrence of adjudicated 
events, a log rank test stratified by the randomization stratification factor (presence of type 2 
diabetes at enrollment [yes/no]) will be used.  Kaplan-Meier (KM) estimates of the distribution 
of the time-to-event will be tabulated and graphed by treatment group.  The tabulation will 
include the KM estimate of the medians and corresponding 95% confidence intervals (CIs), if the 
medians can be estimated.  The number and percent of subjects censored and with events will be 
presented.  The hazard ratio and 95% CI will be determined based on a Cox regression model 
stratified by randomization strata to estimate the magnitude of the effect.  Subjects without any 
documentation of events will be censored at the date of last contact by the end of the Double-
Blind Phase. 
In addition, treatment groups will be compared on each component of the outcome events. 
The percentage of subjects who reported any adjudicated events will be analyzed using a CMH 
test stratified by the randomization strata (presence of type 2 diabetes at enrollment [yes/no]).  
Percentage of subjects who reported each component of the outcome events will also be analyzed 
separately in a similar manner.

Handling of Missing Data 
Subjects who discontinue investigational product are expected to continue in the study until 
study termination. 
In order to determine the effect of missing data on the analysis, efficacy endpoints will be 
analyzed using different methods of imputation as described below. 
17.9.1. 
Time-to-Event Endpoints 
For the time-to-event analyses, subjects who do not experience an event will be censored at the 
time of their last contact.   
All time-to-event endpoints include only adjudicated events.  Sensitivity analyses may consider 
all events regardless of adjudication.  Events with discrepant adjudication will be analyzed using 
both results.

Confidential and Proprietary 
17.9.2. 
Quantitative Endpoints 
For exploratory efficacy endpoints utilizing an ANCOVA model or the Wilcoxon Rank Sum 
Test, observed cases will serve as the primary analysis.  Sensitivity analyses to assess the effect 
of missing data may be conducted where missing data is imputed using last observation carried 
forward.  The last on-treatment value, scheduled or unscheduled, will be carried forward to the 
missing timepoint. 
Sensitivity analyses of ANCOVA models for exploratory efficacy endpoints will also be 
evaluated using a restricted maximum likelihood based mixed-effect repeated measures model 
where no imputations will be made for missing values. 
17.9.3. 
Responder Endpoints 
For the primary analyses, in which subjects are classified as either a responder or a non-
responder (binary outcome), any subject who does not provide an assessment at the specified 
timepoint for the defining of response will be considered to be a non-responder.  That is, for the 
percentage of responders, the subject will be included in the denominator and will not contribute 
to the numerator.  Additional details regarding the secondary histological endpoints are provided 
in the SAP. 
An “observed cases” analyses will also be conducted as sensitivity analyses, excluding those 
subjects who do not provide an assessment at the specified timepoint for the defining of 
response.  That is, for the percentage of responders, the subject will not be included in the 
numerator or the denominator. 
17.9.4. 
Incidence Endpoints 
For the analyses of the percentage of subjects who reported any of the adjudicated clinical 
outcome events or adjudicated cardiovascular events, all subjects, regardless of whether one has 
reported any adjudicated events will be included in the denominator, and only subjects with 
adjudicated events will contribute to the numerator.  This represents the proportion of subjects 
experiencing events to number of subjects at risk. 
Sensitivity analyses may consider all events regardless of adjudication.  Events with discrepant 
adjudication will be analyzed using both results.

diabetes mellitus AEs), adjudicated CV events, adjudicated AKI events, adjudicated events of 
hepatic injury, vital signs, electrocardiograms (ECGs), pruritus VAS, and clinical laboratory 
results. 
Safety data will be summarized by treatment group using the Safety Population. 
17.11.1. 
Adverse Events 
AEs will be coded using the Medical Dictionary for Regulatory Activities (MedDRA).  
Summary tables of treatment-emergent AEs will be provided.  The incidence of TEAEs will be 
tabulated by system organ class and preferred term for each treatment group, and by severity and 
relationship to treatment.  Summaries of TEAEs leading to investigational product 
discontinuation and SAEs will be provided. 
Adverse events of special interest, to be specified in the SAP, will be summarized for each 
treatment group. 
17.11.2. 
Hepatic and Renal Safety Adjudication 
Potential events of hepatic injury and AKI will be adjudicated during the study (Section 17.14).  
The adjudication of the events of hepatic injury will be separate from the adjudication of events 
for the assessment of outcomes in this study.  The adjudication of potential events of hepatic 
injury and AKI will be further defined in the HSAC charter and the Renal Adjudication 
Committee charter, respectively. 
17.11.3. 
Cardiovascular Event Adjudication 
Specific details of the events that will be adjudicated by the Cardiovascular Adjudication 
Committee are described in the respective adjudication charters.  Any changes to either the 
adjudication process or changes to specific events to be adjudicated will be addressed in the 
charters and will be communicated to all study sites. 
Adjudicated cardiovascular events include core MACE (cardiovascular death, nonfatal 
myocardial infarction, and nonfatal stroke) and expanded MACE (unstable angina requiring 
hospitalization, transient ischemic attack, peripheral or coronary revascularization procedures, 
hospitalization for congestive heart failure and arrhythmias).  Any hospitalization (≥24 hours) 
where a cause has not been identified by the Investigator will be considered as a cardiovascular 
event and sent for adjudication.  Other events potentially related to adverse cardiovascular 
outcomes are defined in Appendix E and will be included in the Cardiovascular Adjudication 
Committee Charter for adjudication.   
Summaries of adjudicated cardiovascular events will include the incidence of TEAEs, the 
incidence of serious TEAEs, and a time-to-event analysis as described below.  All summaries of 
incidence will include the associated exact binomial 95% CI.

Cardiovascular Risk Assessment 
The following cardiovascular risk assessments will be calculated: 
• 10-year ASCVD Risk based on Pooled Cohorts Equation 
• FRS 
• Reynolds score 
• SCORE 
Each score is derived from a subject’s age, sex, smoking status, total cholesterol, HDL, and LDL 
levels, systolic blood pressure, diastolic blood pressure, and other factors including family 
history, BMI, ethnicity, and medications.

will be summarized.  For additional exploratory analyses, please refer to SAP for more details. 
17.13. 
Data Monitoring Committee 
An independent data monitoring committee (DMC) will include hepatologists, pharmaceutical 
physicians, epidemiology/cardiology expert(s), DILI expert(s), and statistician(s); they will not 
be involved in the study as Investigators, adjudication committee members, or consultants.  The 
DMC will have oversight over the study conduct as defined by the DMC charter.  All members 
will have considerable experience with clinical study conduct and DMCs.  Any candidate found 
to have a conflict of interest or whose name is listed on the FDA debarment list will not be 
offered membership.  Conflicts of interest will be assessed regularly, and if members are found 
to have a new conflict of interest they will be replaced. 
The DMC will review the safety data, which will include AE data as well as lab values.  PK 
results will be made available to the DMC as appropriate. 
The DMC will meet approximately quarterly at scheduled meetings and ad hoc meetings will be 
convened, as appropriate, to review PK, safety and efficacy data as well as the adjudication 
assessments from the 4 adjudication committees listed in Section 17.14.  Based on review of 
these data, the DMC will advise the Sponsor on the validity and scientific merit of continuing the 
study. 
Written minutes of both the open and closed DMC sessions will be prepared.  The closed 
minutes will be made available to the appointed Sponsor representatives only after the database

Summary tables reviewed by the DMC during closed sessions will be unblinded and include an 
overall column containing information regarding all subjects and separate treatment columns 
with fake labels, ie, the actual treatment groups are used but are not identified.  Data reviewed 
during the meetings will include, at a minimum, disposition, demographics, exposure, clinical 
laboratory results, MedDRA-coded AEs, and AEs leading to early withdrawal of investigational 
product.  At each meeting, detailed narratives of interval SAEs (including events resulting in 
death) are reviewed by the DMC in addition to a cumulative list of all SAEs.  In addition, 
specific summary data focused on hepatic and renal safety are reviewed by the DMC, including 
an aggregate unblinded summary of adjudicated cases of suspected hepatic injury and AKI, 
provided on a quarterly basis or ad hoc as appropriate. 
The DMC may agree to adjust meeting frequency based upon actual and projected safety and 
efficacy data availability.  Adjustments to or stopping of the protocol-defined doses may be 
considered based on DMC evaluation of OCA safety and tolerability. 
All Investigators and responsible IRBs/IECs will be informed of any decisions made by the 
Sponsor based on recommendations from the DMC relating to subject safety that alter the 
conduct of this study.  The Investigators will inform the subjects of such actions and the 
protocol, patient information sheet, and ICF will be revised, as appropriate. 
17.14. 
Adjudication Committees 
Potential liver-related clinical outcomes and potential events of hepatic injury, AKI, MACE, 
deaths, and hospitalizations (depending on the cause) that occur after administration of the first 
dose of investigational product will be reviewed by the following blinded adjudication 
committees, depending on event type, before inclusion in any analysis.  The 4 committees and 
event types they are responsible for adjudicating are as follows: 
• Cardiovascular Adjudication Committee:  Adjudicates all potential MACE, 
(including all deaths) and hospitalizations (depending on the cause) 
• Hepatic Outcomes Committee:  Adjudicates all deaths and potential liver-related 
clinical outcomes  
• HSAC:  Adjudicates all events of potential hepatic injury 
• Renal Adjudication Committee:  Adjudicates all potential events of AKI 
Each adjudication committee will have a charter that documents the reporting of events by the 
study site, definition of the potential events to be adjudicated, supply of source documentation to 
the committee, entire data flow and process from committee membership, review of the events 
by the committee, reporting of the final assessment, and the working procedures of the 
committee. 
The adjudication committee members will include experts with relevant adjudication experience; 
they will not be involved in the study as Investigators, DMC members, or consultants.  Specific 
details of the events that will be adjudicated by the Cardiovascular Adjudication Committee, 
Hepatic Outcomes Committee, HSAC, and the Renal Adjudication Committee are described in 
the respective adjudication charters.  Any changes to either the adjudication process or changes 
to specific events to be adjudicated will be addressed in the charters and will be communicated to

debarment list is not offered membership.  Conflicts of interest are assessed regularly, and if 
members are found to have a new conflict of interest, they will be replaced. 
The adjudication of potential events will be based on available source documentation, including 
but not limited to individual clinical study data, hospital records, histology, discharge summaries, 
and/or death certificates.  The adjudication committees will not receive any individual subject 
treatment or site-specific information.  All protected health information will remain confidential 
and will not be available to the adjudication committee.  The assessment of events will be 
conducted in compliance with study-specific procedures, manuals, GCP, and all other applicable 
regulatory requirements, including the archiving of essential documents. 
18. 
DIRECT ACCESS TO SOURCE DATA/DOCUMENTS 
18.1. 
Study Monitoring 
Study records at each site will be monitored at regular intervals by a representative of the 
Sponsor, the CRA.  The role of the CRA is to aid the Investigator in the maintenance and 
documentation of complete, accurate, legible, well organized, and easily retrievable data.  In 
addition, the CRA will ensure the Investigator's understanding of all applicable regulations 
concerning the clinical evaluation of the investigational product and will ensure an understanding 
of the protocol, reporting responsibilities and the validity of the data.  This will include ensuring 
that full and appropriate essential documentation is available. 
In order to perform this role, the CRA must perform source data verification and as such must be 
given access to the subject’s primary source documentation (eg, paper or electronic medical 
records such as consent to participate in the study, visit dates, screening and randomization 
numbers, demographic information, medical history, disease history, physical examination, vital 
signs, laboratory assessments [copy of laboratory reports], AEs, concomitant medications, dates 
of dispensing investigational product, ECGs, etc.) that support data entries in the eCRF.  The 
eCRF must be completed promptly after each visit to allow the progress and results of the study 
to be closely followed by the Medical Monitor. 
The Investigator may exercise judgment in allowing the CRA access to particular sections of the 
subject's medical records if these are deemed irrelevant to the performance, observations, or 
conduct of this study. 
18.2. 
Audits and Inspections 
The Investigator should understand that it may be necessary for the Sponsor, the IEC/IRB, and/or 
regulatory agencies to conduct one or more site audits during or after the study and agrees to 
allow access to all study related documentation and information and be available for discussion 
about the study. 
19. 
QUALITY CONTROL AND QUALITY ASSURANCE 
Logic and consistency checks will be performed on all data entered into the eCRF or ultimately 
transferred into the database to ensure accuracy and completeness.   

Protocol 747-304

Training sessions, regular monitoring of the study at the study site by the Sponsor or designated 
personnel (eg, CRA), instruction manuals, data verification, cross checking, and data audits will 
be performed to ensure quality of all study data.  Investigators’ meetings and/or onsite study 
initiations will be performed to prepare Investigators and other study site personnel for 
appropriate collection of study data. 
To ensure compliance with GCP and all applicable regulatory requirements, the Sponsor may 
conduct a quality assurance audit.  Please see Section 18.2 for more details regarding the audit 
process. 
20. 
ETHICS 
20.1. 
Ethics Review 
The final study protocol, including the final version of the ICF and/or other subject information, 
must be approved or given a favorable opinion in writing by an IRB/IEC as appropriate.  The 
Investigator must submit written IRB/IEC approval to Intercept before he or she can enroll any 
subject into the study.  The Investigator is responsible for providing the IB and any other 
available safety information and information about payments and compensation available to 
study subjects to the IRB/IEC for review. 
The Investigator is responsible for informing the IRB/IEC of any amendment to the protocol in 
accordance with local requirements.  A favorable opinion on amendments will be obtained prior 
to implementation, unless the amendment is necessary to reduce immediate risk to study 
participants.  In addition, the IRB/IEC must approve all advertising used to recruit subjects for 
the study.  The protocol must be reapproved by the IRB/IEC upon receipt of amendments and 
annually, as local regulations require. 
The Investigator is also responsible for providing the IRB/IEC with reports of any reportable 
serious adverse drug reactions from any other study conducted with the investigational product, 
according to local regulations and guidelines.  The Sponsor will provide this information to the 
Investigator. 
Progress reports and notifications of SARs will be provided to the IRB/IEC according to local 
regulations and guidelines.  Investigators or the Sponsor or its designee will provide reports to 
the IRB/IEC as requested, at a minimum annually, and after the study is complete. 
20.2. 
Ethical Conduct of the Study 
The study will be performed in accordance with ethical principles that have their origin in the 
Declaration of Helsinki and are consistent with ICH/GCP, applicable regulatory requirements 
and the Sponsor’s policies. 
20.3. 
Written Informed Consent 
The Investigator(s) at each center will ensure that the subject is given full and adequate oral and 
written information about the nature, purpose, possible risks, and benefit of the study.  Subjects 
must also be notified that they are free to discontinue from the study at any time.  The subject

should be given the opportunity to ask questions and allowed time to consider the information 
provided. 
The subject’s signed and dated ICFs must be obtained before conducting any study procedures. 
The Investigator(s) must maintain the original, signed ICF.  A copy of the ICF must be given to 
the subject. 
20.4. 
Subject Confidentiality and Data Protection 
All information obtained during the conduct of the study with respect to the subject will be 
regarded as confidential, and confidentiality of all subjects will be maintained.  Monitors 
(eg, CRA, Medical Monitor), auditors, and inspectors will require access to a subject’s medical 
notes for the purpose of source document verification, but the subject’s confidentiality will be 
maintained at all times.  An agreement for disclosure of any such information will be obtained in 
writing and is included in the statement of informed consent.  The study data shall not be 
disclosed to a third party (with the exception of auditors and/or regulatory authorities) without 
the written consent of the Sponsor.  All data shall be secured against unauthorized access. 
The Investigator will maintain a list of subjects’ names and identifying information (eg, subject’s 
hospital number, unique subject number).  This list will not be collected by the Sponsor. 
The ICF will explain that study data will be stored in a computer database, maintaining 
confidentiality in accordance with national data protection legislation.  All data computer 
processed by the Sponsor or designee will be identified by unique subject number/randomization 
code/site number only.   
When personal data on subjects are stored or processed by computer, the data must be protected 
to prevent disclosure to unauthorized third parties.  The pertinent sections of the data protection 
laws in the country in which the protocol is being conducted will be complied with in full. 
The ICF will explain that, for data verification purposes, authorized representatives of the 
Sponsor, regulatory authorities, or IEC/IRBs may require direct access to parts of the hospital or 
study site records relevant to the study, including subject’s medical history. 
21. 
INVESTIGATOR OBLIGATIONS 
The Investigator or a medically trained designee will be responsible for obtaining written 
informed consent and for the care of the subjects for the duration of the study.  If the Investigator 
is not present in the study site during the assessment, he or she will leave instructions for the 
study site staff and a telephone number where he or she can be reached. 
Named physician(s) will be responsible for the medical follow-up of subjects, as applicable. 
21.1. 
Adverse Event Reporting 
The Investigator is responsible for recording AEs reported by the subject or discovered by any 
other means during the study.  In agreeing to the provisions of this protocol, the Investigator 
accepts all legal responsibilities for immediate reporting of SAEs to the Sponsor 
(Section 16.1.7).

21.2. 
Protocol Deviations 
The Investigator is not permitted to deviate from the protocol in any significant way without 
proper notification to the Sponsor (or designee).  Only the Sponsor may amend the protocol.  
Any change in study conduct considered necessary by the Investigator will be made only after 
consultation with the Sponsor, who will then issue a formal protocol amendment to implement 
the change and obtain regulatory approval.  The only exception is when the Investigator 
considers a subject’s safety to be compromised if immediate action is not taken. 
21.3. 
Regulatory Documentation 
The following regulatory documentation must be completed or provided and maintained: 
• Approved ICFs (all versions) 
• IRB/IEC approvals (of protocol/amendments, subject questionnaires, etc)  
• Form FDA 1572 (US only); in lieu of 1572 (for ex-US) 
• Current medical license of Investigators 
• Curriculum vitae of Investigators 
• Laboratory certification and reference ranges 
• Financial disclosure forms 
21.4. 
Ethics Review (IRB/IEC) 
Please see Section 20.1 for the Investigator’s responsibilities regarding ethics review. 
21.5. 
Archiving and Record Retention 
The Investigator should retain all correspondence relating to this study in the Investigator Site 
File (ISF).  Any study documents stored elsewhere should have their location referenced in the 
ISF. 
All documents relating to the study including the ISF itself, source documents and subject 
medical files (retained per country specific regulations), completed study subject log and 
confidential subject identification list will be retained by the Investigator until at least 2 years 
after the last approval of a marketing application in an ICH region and until there are no pending 
or contemplated marketing applications in an ICH region or at least 2 years have elapsed since 
the formal discontinuation of clinical development of the investigational product.  These 
documents should be retained for a longer period, however, if required by the applicable 
regulatory requirement(s) or if needed by the Sponsor.  In the event that storage of records 
becomes a problem at any time during this period, the Sponsor should be consulted for 
assistance.  At the end of the minimum period, the Investigator should obtain written 
authorization from the Sponsor before the destruction of any records.  The Investigator will 
notify the Sponsor if ownership of documents or responsibility for the study site is transferred.  
The Sponsor will inform Investigators should it become aware of any changes in storage 
requirements.

PUBLICATION POLICY 
The Sponsor intends to publish the results of all of the clinical studies that it Sponsors consistent 
with the Declaration of Helsinki.  Consistent with the recommendations of the editors of several 
leading medical journals, the International Committee of Medical Journal Editors (ICMJE), 
authorship of publications resulting from Intercept-sponsored studies should fairly recognize the 
activities of those that have made a significant contribution to the study (http://www.icmje.org).  
Thus, it is anticipated that authorship will reflect the contribution made by the Sponsor 
personnel, the Investigators and others involved, such as statisticians.   
In recent years, issues about conflicts of interest and accuracy of the study data have been raised 
in the medical press.  Accordingly, the Sponsor has developed publication guidelines for clinical 
studies that are appropriate for this study.  Key issues include the following: 
• Clinical Trial Registries (eg, www.clinicaltrials.gov, www.clinicaltrialsregister.eu):  
A description of the study and relevant design elements (eg, basic design, objectives 
and endpoints, sample size, study population, and key inclusion/exclusion criteria) 
and results will be published online in a manner consistent with applicable regulatory 
guidelines. 
• Overview:  Investigators, reviewers, and editors will have the right to audit the data to 
verify its accuracy. 
• Responsibility:  Each Investigator is responsible for the accuracy and completeness of 
all data from her/his site.  The Sponsor (or its representatives) is responsible for the 
accuracy of the data entered into the study databases and the analyses conducted. 
• Data Management:  The Sponsor will establish data management plan and SAP.  The 
Investigators will have the opportunity to provide input into the plans.  The 
Investigators will have the right to review the audit reports and data resolution 
decisions prior to the establishment of a clean file.  The Investigators will have the 
right to appoint appropriately qualified auditors, with GCP experience, to audit the 
Sponsor’s data prior to the establishment of a clean file.  The Investigators must 
provide adequate notice (at least 2 months) to the Sponsor of their intention to audit a 
study.  The audit should be conducted in a timely manner to allow the resolution of 
discrepancies before a clean file is established.  The Investigators will bear all the 
costs for the conduct of audits that they initiate, except those related to the resolution 
of data queries which the Sponsor will bear.  Such audits must be conducted in such a 
manner as to minimize the time to create the clean file. 
• Authorship:  Intercept, in collaboration with the Investigators, will establish the 
appropriate authorship and responsibility for drafting study documents in accordance 
with the principles of the ICMJE.  All manuscripts will be reviewed and agreed upon 
before submission for publication by all authors. 
• Single Center Publication and Additional Publications:  This is a multicenter study 
and is designed to be published with complete data from all the study sites.  Single 
center publications are therefore not considered appropriate.  Any such publications 
should clearly state that the data are “extracted” from a multicenter study and that the 

Protocol 747-304 
Version 7.0:  16Jun2021
 
Page 155
 
Confidential and Proprietary 
study was not intended, or statistically powered, for data presentation by a single 
study site. 
• Intercept Review of External Manuscripts:  Consistent with this, Investigators must 
submit any drafts of any publications or presentations that may arise from this study 
to the Sponsor for review and approval and to ensure consistency with the policy in 
this protocol at least 30 days prior to submission for publication or presentation.  The 
Sponsor will have the right to request appropriate modification to correct facts and to 
represent its, or the Publication Committee’s, opinion if these differ with the proposed 
publication. 
• Confidentiality:  Investigators will conduct all interactions with the company and 
with third parties consistent with the executed confidentiality agreements.  While 
publication, by intention, presents the critical scientific data in a public forum, some 
information (such as future plans, results of preclinical studies or chemical formulae) 
may still need to remain confidential. 
• Medical Journal Review:  Upon request, all pertinent study data and information will 
be made available as supplemental information for journal editors and reviewers to 
evaluate and audit, eg, protocol and amendments, data tabulations, etc.  Arrangements 
will be made to maintain the confidentiality of such supplemental information.  
Arrangements will also be made to maintain the confidentiality of the identity of 
journal reviewers.  Records will be maintained of which documents and datasets were 
reviewed.

Event 
Definitions 
the laboratory should be used.  If the ninety-ninth percentile of the URL or the 
URL for myocardial necrosis is not available, the MI decision limit for the 
particular laboratory should be used as the URL.  Laboratories can also report 
both the ninety-ninth percentile of the upper reference limit and the MI decision 
limit.  Reference limits from the laboratory performing the assay are preferred 
over the manufacturer’s listed reference limits in an assay’s instructions for use.  
In general, troponins are preferred.  Creatine kinase-myocardial band (CK-MB) 
should be used if troponins are not available, and total creatine kinase (CK) may 
be used in the absence of CK-MB and troponin. 
For MI subtypes, different biomarker elevations for CK, CK-MB, or troponin will 
be required.  The specific criteria will be referenced to the URL. 
Since it is not practical to stipulate the use of a single biomarker or assay, the 
locally available results are to be used as the basis for adjudication.  However, if 
possible, using the same cardiac biomarker assay and preferably, a core 
laboratory, for all measurements reduces inter-assay variability. 
Since the prognostic significance of different types of MIs (eg, periprocedural MI 
versus spontaneous MI) may be different, outcomes for these subsets of subjects 
may be evaluated separately. 
c) 
ECG Changes 
Electrocardiographic changes can be used to support or confirm a MI. Supporting 
evidence may be ischemic changes and confirmatory information may be new 
Q waves. 
ECG manifestations of acute myocardial ischemia (in absence of left ventricular 
hypertrophy [LVH] and left bundle branch block [LBBB]) include: 
• 
ST elevation: New ST elevation at the J point in two contiguous leads 
with the cut-points: ≥0.1 mV in all leads other than leads V2-V3 where 
the following cut-points apply: ≥0.2 mV in men ≥40 years (≥0.25 mV in 
men <40 years) or ≥0.15 mV in women 
• 
ST depression and T-wave changes: New horizontal or down-sloping ST 
depression ≥0.05 mV in two contiguous leads and/or new T inversion 
≥ 0.1 mV in two contiguous leads with prominent R wave or R/S ratio 
>1. 
The above ECG criteria illustrate patterns consistent with myocardial ischemia.  
In subjects with abnormal biomarkers, it is recognized that lesser ECG 
abnormalities may represent an ischemic response and may be accepted under the 
category of abnormal ECG findings. 
• 
Criteria for pathological Q-wave 
− 
Any Q-wave in leads V2-V3 ≥0.02 seconds or QS complex in leads 
V2 and V3

Transient Ischemic Attack 
(TIA) 
TIA is defined as a transient episode of focal neurological dysfunction caused by 
brain, spinal cord, or retinal ischemia, without acute infarction. 
Stroke (Includes Ischemic 
Stroke, Hemorrhagic Stroke, 
Undetermined Stroke, or 
Stroke Disability) 
Stroke is defined as an acute episode of focal or global neurological dysfunction 
caused by brain, spinal cord, or retinal vascular injury as a result of hemorrhage 
or infarction. 
A. Ischemic Stroke: Ischemic stroke is defined as an acute episode of focal 
cerebral, spinal, or retinal dysfunction caused by infarction of central 
nervous system tissue. 
Hemorrhage may be a consequence of ischemic stroke.  In this situation, 
the stroke is an ischemic stroke with hemorrhagic transformation and not 
a hemorrhagic stroke. 
B. Hemorrhagic Stroke: Hemorrhagic stroke is defined as an acute episode 
of focal or global cerebral or spinal dysfunction caused by 
intraparenchymal, intraventricular, or subarachnoid hemorrhage. 
C. Undetermined Stroke: Undetermined stroke is defined as an acute 
episode of focal or global neurological dysfunction caused by presumed 
brain, spinal cord, or retinal vascular injury as a result of hemorrhage or 
infarction but with insufficient information to allow categorization as A 
or B.  
Stroke Disability: Disability should be measured by a reliable and valid scale in 
all cases, typically at each visit and 90 days after the event.  For example, the 
modified Rankin Scale may be used to address this requirement: 
Scale Disability 
0

No significant disability despite symptoms; able to carry out all 
usual duties and activities 
2 
Slight disability; unable to carry out all previous activities, but

Heart Failure (A HF event 
includes hospitalization for 
HF and may include urgent 
outpatient visits) 
A HF hospitalization is defined as an event that meets ALL of the following 
criteria: 
1. The subject is admitted to the hospital with a primary diagnosis of HF 
2. The subject’s length-of-stay in hospital extends for at least 24 hours (or a 
change in calendar date if the hospital admission and discharge times are 
unavailable) 
3. The subject exhibits documented new or worsening symptoms due to HF 
on presentation, including at least ONE of the following: 
• 
Dyspnea (dyspnea with exertion, dyspnea at rest, orthopnea, 
paroxysmal nocturnal dyspnea) 
• 
Decreased exercise tolerance 
• 
Fatigue 
• 
Other symptoms of worsened end-organ perfusion or volume 
overload (must be specified and described by the protocol) 
4. The subject has objective evidence of new or worsening HF, consisting 
of at least TWO physical examination findings OR one physical 
examination finding and at least ONE laboratory criterion), including: 
a. 
Physical examination findings considered to be due to HF, including 
new or worsened: 
i. Peripheral edema 
ii. Increasing abdominal distention or ascites (in the absence of 
primary hepatic disease) 
iii. Pulmonary rales/crackles/crepitations 
iv. Increased jugular venous pressure and/or hepatojugular reflux 
v. S3 gallop 
vi. Clinically significant or rapid weight gain thought to be related to 
fluid retention 
b. Laboratory evidence of new or worsening HF, if obtained within 
24 hours of presentation, including: 
i. 
Increased B-type natriuretic peptide (BNP)/ N-terminal pro-
BNP (NT pro-BNP) concentrations consistent with 
decompensation of HF (such as BNP >500 pg/mL or NT-
proBNP >2,000 pg/mL).  In subjects with chronically elevated 
natriuretic peptides, a significant increase should be noted 
above baseline. 
ii. Radiological evidence of pulmonary congestion

Abnormal results of any invasive functional diagnostic test [eg, 
coronary flow reserve (CFR) or fractional flow reserve (FFR)]  
Comment:  Target lesion revascularization of a >70% diameter stenosis by QCA 
in the absence of the above signs or symptoms may be considered clinically-
driven. 
Comment:  In the absence of QCA data or if a ≤50% stenosis is present, TLR may 
be considered clinically-driven by the Adjudication Committee (AC) if severe 
ischemic signs and symptoms attributed to the target lesion are present. 
Non-Target Lesion and 
Non-Target Lesion 
Revascularization: 
A lesion for which revascularization is not attempted or one in which 
revascularization is performed using a non-study device, respectively. 
Non-Target Vessel and Non-
Target Vessel 
Revascularization: 
A vessel for which revascularization is not attempted or one in which 
revascularization is performed using a non-study device, respectively. 
Percutaneous Coronary 
Intervention (PCI) Status: 
a. 
Elective: The procedure can be performed on an outpatient basis or during a 
subsequent hospitalization without significant risk of MI or death.  For stable 
inpatients, the procedure is being performed during this hospitalization for 
convenience and ease of scheduling and NOT because the subject's clinical 
situation demands the procedure prior to discharge. 
b. Urgent: The procedure should be performed on an inpatient basis and prior to 
discharge because of significant concerns that there is risk of myocardial 
ischemia, MI, and/or death.  Subjects who are outpatients or in the 
emergency department at the time that the cardiac catheterization is requested 
would warrant hospital admission based on their clinical presentation. 
c. 
Emergency:  The procedure should be performed as soon as possible because 
of substantial concerns that ongoing myocardial ischemia and/or MI could 
lead to death.  "As soon as possible" refers to a subject who is of sufficient 
acuity that one would cancel a scheduled case to perform this procedure 
immediately in the next available room during business hours, or one would 
activate the on-call team were this to occur during off-hours. 
d. Salvage:  The procedure is a last resort. The subject is in cardiogenic shock 
when the PCI begins (ie, the time at which the first guide wire or 
intracoronary device is introduced into a coronary artery or bypass graft for 
the purpose of mechanical revascularization) OR within the last ten minutes 
prior to the start of the case or during the diagnostic portion of the case, the 
subject has also received chest compressions or has been on unanticipated 
circulatory support (eg, intra-aortic balloon pump, extracorporeal membrane 
oxygenation, or cardiopulmonary support). 
Percutaneous Coronary 
Intervention (PCI): 
Placement of an angioplasty guide wire, balloon, or other device (eg, stent, 
atherectomy catheter, brachytherapy delivery device, or thrombectomy catheter) 
into a native coronary artery or coronary artery bypass graft for the purpose of 
mechanical coronary revascularization.  In the assessment of the severity of 
coronary lesions with the use of intravascular ultrasound, coronary flow reserve

Definitions 
(CFR), or fractional flow reserve (FFR), insertion of a guide wire will NOT be 
considered PCI. 
Procedural Success: 
Achievement of <30 % residual diameter stenosis of the target lesion assessed by 
visual inspection or QCA and no in-hospital major adverse cardiac events 
(MACE, a composite of death, MI, or repeat coronary revascularization of the 
target lesion).  Ideally, the assessment of the residual stenosis at the end of the 
procedure should be performed by an angiographic core laboratory. 
Comment: For some device interventions (eg, balloon angioplasty), achievement 
of <50% diameter stenosis by visual inspection or QCA is an acceptable 
definition for procedural success. 
Target Lesion: 
Any lesion treated or attempted to be treated during the PCI with the study device.  
The target lesion includes the arterial segment treated with the study device (stent, 
in most cases) plus 5 mm proximal and 5 mm distal to the treatment site. 
Target Lesion Failure 
(TLF): 
The composite of ischemia-driven revascularization of the target lesion, MI 
related to the target vessel, or cardiac death related to the target vessel.  If it 
cannot be determined with certainty whether the MI or death was related to the 
target vessel, it is considered a TLF. 
Target Lesion 
Revascularization (TLR): 
Any repeat percutaneous intervention of the target lesion (including 5 mm 
proximal and 5 mm distal to the target lesion) or surgical bypass of the target 
vessel performed for restenosis or other complication involving the target lesion.  
In the assessment of TLR, angiograms should be assessed by an angiographic 
core laboratory (if designated) and made available to the AC for review upon 
request. 
Target Vessel: 
A major native coronary artery (eg, left main coronary artery, left anterior 
descending coronary artery, left circumflex coronary artery, or right coronary 
artery) or bypass graft containing the target lesion.  A native coronary artery 
target vessel includes the arterial segments upstream and downstream to the target 
lesion plus major side branches. 
Target Vessel Failure 
(TVF): 
The composite of ischemia-driven revascularization of the target vessel, MI 
related to the target vessel, or cardiac death related to the target vessel.  If it 
cannot be determined with certainty whether the MI or death was related to the 
target vessel, it is considered a TVF. 
Target Vessel, Non-Target 
Lesion, and Target Vessel, 
Non-Target Lesion 
Revascularization: 
Any lesion or revascularization of a lesion in the target vessel other than the target 
lesion, respectively. 
Target Vessel 
Revascularization (TVR): 
Any repeat percutaneous intervention or surgical bypass of any segment of the 
target vessel. In the assessment of TVR, angiograms should be assessed by an 
angiographic core laboratory (if designated) and made available to the CEC for 
review upon request. 
Vascular Complications: 
• 
Access site hematoma:  Development of a new, localized collection of blood 
at a vascular access site sufficient to produce a palpable mass within 
72 hours of a procedure.

Minimum Lumen Diameter 
(MLD): 
The mean minimum lumen diameter (typically measured in-lesion, in-stent, and 
in-segment) derived from two orthogonal views by QCA. 
No Reflow: 
An acute reduction in coronary flow (TIMI grade 0-1) in the absence of 
dissection, thrombus, spasm, or high-grade residual stenosis at the original target 
lesion. 
Percent Diameter Stenosis 
(% DS): 
The value calculated as 100 x (1 – MLD/RVD) using the mean values determined 
by QCA from two orthogonal views (when possible). 
Reference Vessel Diameter 
(RVD): 
Defined as the average of normal segments within 10 mm proximal and 10 mm 
distal to the target lesion from two orthogonal views using QCA. 
Restenosis: 
Re-narrowing of the vessel following the treatment of a prior stenosis  
• 
Binary restenosis: A diameter stenosis of > 50% at the previously treated 
lesion site, including the originally treated site plus the adjacent vascular 
segments 5 mm proximal and 5 mm distal to the site. 
• 
In-stent restenosis (ISR): A previously stented lesion with a > 50% diameter 
stenosis. 
Thrombus (Angiographic): 
A discrete, mobile, intraluminal filling defect with defined borders with or 
without associated contrast staining. 
TIMI (Thrombolysis in 
Myocardial Infarction) Flow 
Grades: 
• 
Grade 0 (no perfusion): There is no antegrade flow beyond the point of 
occlusion. 
• 
Grade 1 (penetration without perfusion): The contrast material passes 
beyond the area of obstruction but “hangs up” and fails to opacify the entire 
coronary bed distal to the obstruction for the duration of the 
cineangiographic filming sequence. 
• 
Grade 2 (partial perfusion): The contrast material passes across the 
obstruction and opacifies the coronary bed distal to the obstruction. 
However, the rate of entry of contrast material into the vessel distal to the 
obstruction or its rate of clearance from the distal bed (or both) is 
perceptibly slower than its entry into or clearance from comparable areas 
not perfused by the previously occluded vessel (eg, the opposite coronary 
artery or the coronary bed proximal to the obstruction). 
• 
Grade 3 (complete perfusion): Antegrade flow into the bed distal to the 
obstruction occurs as promptly as antegrade flow into the bed proximal to 
the obstruction and clearance of contrast material from the involved bed is 
as rapid as from an uninvolved bed in the same vessel or the opposite artery.

Elective: An elective procedure is one that is scheduled and is performed 
on a subject with stable disease, or in whom there is no urgency and/or 
increased morbidity or mortality associated with a planned procedure.  
Target Lesion: 
A target lesion is any vascular segment treated or attempted to be treated during 
the trial procedure with the index device.  The target lesion is the treated segment 
starting 10 mm proximal and ending 10 mm distal to the index device or therapy 
(stent, balloon, atherectomy catheter, or aortic stent-graft). 
Target Vessel: 
A target vessel is any vessel (eg, non-cardiac or non-intracranial) that contains the 
target lesion treated with the study device.  The target vessel includes the target 
lesion as well as the entire length of native vessel upstream and downstream from 
the target lesion, including side branches.  For the arteries of the leg, the 
vasculature is divided into 3 vessel “levels:” aorto-iliac, femoral-popliteal, and

Revascularization (TLR): 
Target lesion revascularization is any repeat intervention of the target lesion 
(including 10 mm proximal and 10 mm distal to the index device, as target lesion 
is defined above) or surgical intervention/bypass of the target vessel performed 
for restenosis or other complication involving the target lesion.  In the assessment 
of TLR, angiograms should be assessed by an angiographic core laboratory (if 
designated).  Angiograms (and core laboratory assessment thereof) and other 
source documentation should be made available to the CEC for review upon 
request. 
Target Vessel 
Revascularization (TVR): 
Target vessel revascularization is any repeat intervention or surgical bypass of

APPENDIX F. SUMMARY OF CHANGES:  747-304 PROTOCOL VERSION 6.0 TO PROTOCOL 
VERSION 7.0 (DATED:  16 JUN 2021) 
Protocol 747-304 was revised to include the following information: 
1) Reorganization and updates to the study objectives and related sections on overall assessments and statistics 
2) Inclusion of Hepatic Safety Adjudication Committee and Renal Adjudication Committee for the adjudication of all events of 
potential hepatic injury and acute kidney injury, respectively.  The protocol was updated to ensure these events will be 
provided to the DMC for inclusion in their review as well as added to the Safety Objectives to be assessed at the End of Study. 
3) Updated process for the monitoring and management of potential DILI and updated the DILI algorithm and laboratory triggers 
to monitor hepatic injury 
4) Clarification of language on PK sample collection following investigational product interruption or discontinuation and within 
7 days of experiencing a serious adverse event.   
5) Additional sections added to address monitoring and management of renal impairment and nephrolithiasis, hyperglycemia, and 
dyslipidemia.  Additional education and assessments to identify intercurrent illness and/or potential adverse events was added.   
6) Inclusion of local laboratory results and reference ranges into the eCRF 
7) COVID-19-related changes to the protocol 
8) The use of “suspected” was globally updated to “potential” throughout the protocol 
9) Interactive web response system (IWRS) was updated to randomized and trial supply management system (RTSM) to align 
with new vendor terminology

The maximum duration of individual subject participation 
for this study is approximately 2 years and 3 months, 
including a Screening Period of up to 12 weeks, a 1 year 
Double-Blind Phase, and an optional Open-Label Extension 
(OLE) expected to last approximately 1 year. 
The maximum duration of individual subject 
participation for this study is approximately 2 years and 
6 months, including a Screening Period of up to 12 
weeks, an 18-month Double-Blind Phase, and an Open-
Label Extension (OLE) expected to last approximately 
1 year. 
EOS/EOT extended 
from Month 12 to 
Month 18 
 
While a treatment 
duration of 
12 months had 
initially been 
selected, emerging 
evidence suggests 
that 12 months may 
not be optimal to 
evaluate histological 
reversal of NASH 
cirrhosis. As such, 
the 18-month 
duration of the 
treatment period for 
Study 747-304 has 
been selected.

OLE Phase 
Subjects who complete the Double-Blind Month 12 Visit 
(and continue to receive investigational product) are eligible 
to enroll into the OLE.  All subjects will receive OCA upon 
entry into the OLE.  Subjects randomized to placebo in the 
Double-Blind Phase will be re-randomized to either OCA 
10 mg or OCA 10 mg → 25 mg (ie, OCA 10 mg for the first 
3 months of the OLE prior to uptitrating to OCA 25 mg at 
OLE Month 3).  Uptitration will be based on the safety and 
tolerability assessments completed prior to Month 3.  
Subjects randomized to OCA (10 mg or 25 mg dose) during 
the Double-Blind Phase will continue the same dosing 
regimen they received at the end of the Double-Blind Phase; 
however, they will undergo dummy titration to maintain 
study blind until all subjects complete the Double-Blind 
Phase and the database is locked. 
Subjects who complete the Double-Blind Month 18 Visit 
and continue to receive investigational product are 
eligible to enroll into the OLE.  All subjects will receive

unscheduled visit as a confirmatory sample.  Subjects who 
satisfy any of the following exclusion criteria will be 
ineligible for enrollment: 
 
 
 
1. Current or past history of hepatic decompensation such 
as clinically significant ascites (requiring medical 
intervention), variceal bleeding, spontaneous bacterial 
peritonitis, hepatic encephalopathy (Grade I or greater

A sequential approach will be used to perform the 
population PK/PD analysis.  The Bayesian estimates of 
individual PK parameters from the final population PK 
model will be used to generate PK profiles for each subject.  
The change in each PD assessment (eg, C4, FGF 19) over 
time will be incorporated into a maximum effect (Emax) 
model with OCA dose level as an independent variable.  
Estimated model parameters for each individual will be 
derived from prior Emax, and the half maximal effective 
concentration values, and baseline measures of each PD 
assessment.  The appropriate structure of the variance
covariance matrix will also be evaluated.  Fixed and 
random effect parameter estimates and associated 
asymptotic standard errors will be estimated.  Descriptive

PK/PD parameters obtained from individual assessments in 
the population PK/PD model.  These PK/PD analyses will

Exploratory plots for efficacy endpoints and markers

Overview of 
Nonalcoholic 
Steatohepatitis 
and Obeticholic 
Acid 
Despite the seriousness of the disease, there are currently no 
approved therapies for the treatment of NASH nor an 
accepted standard of care.  The therapeutic options for 
NASH are largely limited to lifestyle modifications and 
treatment of concurrent conditions such as diabetes 
(Neuschwander Tetri 2003, Belfort 2006, Sanyal 2010, 
Chalasani 2012).  For patients with NASH without diabetes, 
practice guidelines from the American Association for the 
Study of Liver Diseases recommend the use of vitamin E as 
first line therapy (Chalasani 2012).  
However, there are currently no approved treatments 
targeting the underlying pathophysiology, of progressive 
fibrosis or cirrhosis. 
 
Obeticholic acid (OCA) is a modified bile acid and 
farnesoid X receptor (FXR) agonist that is derived from the 
primary bile acid chenodeoxycholic acid (CDCA). 
OCA’s potent FXR agonist effects make it an attractive 
novel therapeutic agent for NASH due to its multiple FXR-
mediated effects including an increase in insulin sensitivity, 
glucose and lipid metabolism, hepatocyte protection against 
bile acid induced cytotoxicity, anti inflammatory effects in

nonclinical studies have shown several potentially

Section 5.2 
Nonclinical 
Experience with 
OCA 
In addition, OCA plays a broad role in improving glycemic, 
metabolic, and cardiovascular parameters: 
• 
FXR plays a role in bile acid homeostasis, 
metabolism, and clearance (Cariou 2006, 
Ma 2006, Zhang 2008). 
• 
FXR controls glucose metabolism through 
regulation of gluconeogenesis and 
glycogenolysis in the liver, as well as 
regulation of peripheral insulin sensitivity in 
striated muscle and adipose tissue (Zhang 
2006). 
• 
In nonclinical models, FXR agonism is 
associated with beneficial effects on body 
weight and composition (Fu 2004, Xu 2009). 
• 
The absence of endogenous intact FXR 
signaling results in dyslipidemia and a hepatic 
phenotype similar to NASH patients (Zhang 
2008).  Conversely, FXR agonists lower 
plasma triglycerides by repressing hepatic 
sterol regulatory element binding protein 1 c 
(Watanabe 2004) and increased hepatic fatty 
acid oxidation (Savkur 2005). 
In summary, there is strong rationale to advance OCA 
for the treatment of NASH based on its FXR-mediated 
hepatoprotective properties.

• 
In addition, OCA and other FXR agonists are 
anti atherogenic and cardioprotective in 
animal models (Miyazaki Anzai 2010, 
Hartman 2009). 
In summary, there is strong rationale to advance OCA for 
the treatment of NASH based on its FXR-mediated 
hepatoprotective properties, anti fibrotic effects in a NASH 
model, and results indicating that OCA improves glycemia 
by increasing peripheral glucose uptake, enhancing glucose
stimulated insulin secretion, and inhibiting hepatic lipid 
synthesis and content while inducing lipid uptake by 
adipocytes. 
Section 5.3 
Clinical 
Experience with 
Obeticholic 
Acid 
OCA is under investigation for the treatment of multiple 
chronic liver diseases, including the treatment of NASH, 
primary biliary cholangitis (PBC, also called primary 
biliary cirrhosis) [Beuers 2015a, Beuers 2015b, Beuers 
2015c]), primary sclerosing cholangitis, biliary atresia, and 
other chronic liver diseases.  OCA was granted accelerated 
approval by the United States Food and Drug 
Administration (FDA) on 27 May 2016.  Conditional 
approvals were obtained on 12 Dec 2016 in the European 
Union (EU), and by Health Canada on 24 May 2017 under 
the trademark Ocaliva for the treatment of PBC in 
combination with ursodeoxycholic acid (UDCA) in adults 
with an inadequate response to UDCA, or as monotherapy 
in adults unable to tolerate UDCA. 
 
OCA (Ocaliva) has received marketing authorization 
in the United States, Europe, Canada, and several 
other countries for the treatment of primary biliary 
cholangitis (PBC) in combination with ursodeoxycholic 
acid (UDCA) in adults with an inadequate response to 
UDCA, or as monotherapy in adults unable to tolerate 
UDCA.  OCA is currently being developed for the 
treatment of multiple chronic non-viral liver 
diseases, including the treatment of NASH with 
fibrosis, NASH with cirrhosis, primary sclerosing 
cholangitis, and biliary atresia.

in lipid profile, which was attenuated with continued 
treatment and reversed post treatment, needs to be further 
investigated mechanistically and with respect to clinical 
management with standard of care statin therapy.  The 
general adverse event (AE) profile was similar across both 
groups, with the exception of pruritus. 
 
Study 747 209 enrolled subjects with histological evidence 
of definite or probable NASH confirmed by liver biopsy 
and a nonalcoholic fatty liver disease activity score (NAS) 
of 4 or greater, randomized in a 1:1:1:1 ratio to receive 
OCA 5 mg, OCA 10 mg, OCA 25 mg or placebo, orally 
once daily, for 16 weeks.  Randomization was stratified by 
LDL concentration (fasting serum low density lipoprotein 
(LDL) cholesterol at Screening Visit 2; ≤125 mg/dL or 
>125 mg/dL) and baseline fibrosis stage (stage 1, 2 or 
stage 3, 4).  Statin free subjects as well as statin treated 
subjects (following a 4 week statin washout) were eligible 
for enrollment.  All subjects initiated treatment with 
atorvastatin at a dose of 10 mg once daily after 4 weeks of 
OCA treatment.  After 4 weeks of 10 mg atorvastatin 
treatment, dosing was increased to 20 mg once daily, and 
continued for an additional 4 weeks.  After 4 weeks of 
treatment at 20 mg daily dose, atorvastatin dosing could be 
titrated up or down as clinically indicated.

however, this increase was reversed and LDL

Study 747-209 further evaluated the effect of OCA 
and atorvastatin treatment on LDL metabolism in 
subjects with NASH and liver fibrosis to better 
characterize the lipid profile changes observed in the 
FLINT study, as well as their management.  Subjects 
with biopsy-confirmed NASH and fibrosis received 
placebo or OCA 5mg, 10 mg, or 25 mg once daily, for 
up to 4 weeks.  Subjects initiated concurrent 
treatment with atorvastatin 10 mg once daily, 
titrated to 20 mg once daily at Week 8 based on 
tolerability.  At Week 4, subjects experienced an 
approximately 20% to 25% increase in LDLc 
concentrations across all OCA groups.  By Week 8, 
atorvastatin treatment effectively lowered LDLc to 
below baseline levels across all treatment groups.  
Together, these study results suggest that the risk of 
increases in LDLc with OCA use can generally be 
managed by statin use.  Pruritus was the most

Study 117 demonstrated that the PK profile of OCA 
in subjects with NASH fibrosis was consistent with 
what has been observed in healthy subjects and 
largely reflective of enterohepatic recirculation with 
exposure proportional to dose.  Treatment with OCA 
10 mg or 25 mg once daily for 12 weeks was found to 
be safe and well tolerated in NASH subjects with 
fibrosis (including fibrosis stage 1 through stage 4).  
The PD assessments demonstrated FXR activation

Study 747-118 demonstrated that the safety profile of 
10 mg and 25 mg doses of OCA in subjects with 
compensated CP Class A cirrhosis due to NASH was 
similar to the safety observed in healthy subjects,

Rationale for 
Study Design 
NASH is a serious, chronic liver disease with a large unmet 
medical need and no approved therapies.  The incidence of 
NASH is increasing, and NASH is likely to be the leading 
cause of liver transplant by 2020, highlighting the need for 
development of effective therapies that may improve 
steatohepatitis and fibrosis, potentially delaying liver 
transplant or death.  The FLINT study has demonstrated 
that OCA can improve individual features of steatohepatitis 
as well as fibrosis (Neuschwander Tetri 2015).  As fibrosis 
has been consistently shown to be the strongest predictor of 
adverse clinical outcomes, including liver-related death, it 
is critical to prevent further progression of fibrosis and 
preferably reverse fibrosis.  The effects of OCA on fibrosis 
are currently being evaluated in a Phase 3 study in subjects 
with NASH and liver fibrosis.  Patients with cirrhosis in the 
spectrum of NASH disease continuum represent the highest

signaling pathways thus inducing bile acid levels.  Overall 
study duration was determined based on findings in prior 
NASH studies ranging from 6 months to 72 weeks.  While 
the largest Phase 2 study of OCA in NASH patients was 
conducted over a period of 72 weeks, recent reports suggest 
that fibrosis improvement can be observed earlier than 
72 weeks (Sanyal 2016, Loomba 2016).  Modest decreases 
of serum markers of fibrosis (hyaluronic acid [HA], 
procollagen III amino terminal peptide [P3NP], and tissue 
inhibitor of metalloproteinase 1 [TIMP 1]) were seen after 
only 6 weeks of OCA 25 mg treatment (Study 747 203).  
Furthermore, in FLINT, OCA demonstrated reductions in 
fibrosis scores as early as 6 months after treatment with 
OCA, and these reductions were associated with histologic 
fibrosis improvement at 72 weeks.  Therefore, it is

reasonable to expect that a 12 month placebo controlled 
treatment period is sufficient to demonstrate an OCA 
treatment effect and a pattern of responses in this study 
population (Chalasani 2012). 
Addition of 18 Month treatment duration rationale 
 
 
 
 
Rationale for Treatment Duration of 18 Months 
The natural history of NASH with liver fibrosis 
shows that both progression and regression of liver 
fibrosis are slow processes that may take years to 
develop as well as to improve.  A systematic review 
and meta-analysis of paired-biopsy studies has 
shown that a 1-stage change in fibrosis occurs over a 
median of 7.1 years in patients with NASH (Singh 
2015).  Regression of fibrosis in established NASH 
cirrhosis is expected to take even longer (Cheung 
2019).  To date, no clinical trial in subjects with 
NASH cirrhosis has demonstrated efficacy with 
respect to reversal of cirrhosis and there are no 
approved treatment options for NASH cirrhosis. 
As presented above, OCA has shown robust anti-
fibrotic effects based on histologic endpoints in pre-
cirrhotic NASH subjects with liver fibrosis. A 
treatment duration of 12 months was initially 
selected for the placebo-controlled portion of this 
study based on non-histological data (using serum 
biomarkers of fibrosis observed in Study 747-203 
and FLINT). However, the effects of OCA on liver 
histology at earlier time points, including 12 months, 
had not been assessed. The preliminary results of the 
18-month interim analysis from Study 747-303 
showed that OCA 25 mg was superior to placebo,

demonstrating histological improvement of NASH 
fibrosis without worsening of NASH with an effect 
size of ~11% over 18 months of treatment (Younossi 
2019). However, the results also highlighted the slow 
process of regression of liver fibrosis and the 
potential challenges of demonstrating efficacy in 
regression of liver fibrosis within a finite time period. 
To reduce the chance of a false negative study, based 
on the above considerations, the duration of 
treatment in the double-blind phase has been 
extended to 18 months. 
Section 5.5.1 
Risk/Benefit 
Profile of OCA 
in Subjects with 
NASH 
An independent data monitoring committee (DMC) has 
performed detailed reviews of several studies including the 
Phase 3, clinical outcomes study in PBC (747 302) and the 
Phase 3, pivotal study in NASH with fibrosis (747 303).  
The DMC reviewed data (unmasked for PBC and unblinded 
by treatment group for NASH with a total of approximately 
1000 subjects) in closed sessions, which excluded 
participation of the Sponsor.  Based on these reviews, the 
DMC recommended that both studies continue without 
modification providing further support for the lack of safety 
concern and positive benefit risk profile of OCA. 
An independent data monitoring committee (DMC) 
has performed detailed reviews of individual subject 
and aggregate data from both the Phase 3 clinical 
outcomes study in subjects with PBC (Study 747-302) 
and the Phase 3 pivotal studies in subjects with 
NASH fibrosis (Study 747-303) and NASH cirrhosis 
(Study 747-304) on a quarterly basis, in an unblinded 
fashion, and in closed sessions (without the Sponsor’s 
participation).  In the quarterly DMC meetings to 
date, the DMC has recommended the studies 
continue without modification.

to date DMC report analyzing unblinded data on

ongoing clinical studies, an ad hoc DMC review was 
held and the DMC recommended that: 
• 
As it concerned pancreatitis, all studies 
continue without changes. 
• 
For subjects in Study 747-303,

cholecystitis. 
The Sponsor decided to implement the DMC 
recommendations across the NASH program 
Section 5.6 
Importance of 
Monitoring of 
Disease 
Progression 
NASH is a chronic, progressive liver disease; therefore, it is 
important that subjects with NASH are closely monitored to 
ensure early identification of potential disease progression 
to cirrhosis, decompensation and/or liver injury.  The rate 
of progression and risk of decompensation is variable and 
may be rapid in certain patients necessitating closer 
surveillance of patients at risk.  Therefore, more extensive 
safety monitoring and appropriate dosing adjustments, 
interruptions, and discontinuations will be implemented to 
improve subject oversight and safety.  Investigators 
together with the Sponsor’s Medical Monitor or designee 
will consistently and frequently assess individual subjects 
to determine on an ongoing basis the totality of a subject’s 
clinical profile, which includes careful evaluation of signs 
and symptoms of potential hepatic injury and/or 
NASH is a chronic, progressive liver disease with 
variable rates of progression to cirrhosis and hepatic 
decompensation, although both may occur rapidly in 
certain patients. Subjects with NASH cirrhosis have 
accentuated risks relative to subjects with non-
cirrhotic NASH and can transition abruptly from a 
clinically-compensated state to decompensated 
cirrhosis, with the manifestations of portal 
hypertension and impaired synthetic function that 
characterize end-stage liver disease. Subjects with 
NASH cirrhosis must therefore be closely monitored 
to ensure early identification of signs and symptoms 
of decompensation and/or liver injury. In this study, 
close and thorough safety monitoring is paired with 
appropriate investigational product dosing 
adjustment, interruption, and discontinuation to 
improve subject oversight and safety.

decompensation coupled with rules based laboratory 
monitoring. 
Subjects will be monitored for potential hepatic injury 
and/or progression to decompensation (Section 7.4).  
Criteria for implementing dosing adjustments, interruptions, 
or discontinuations, and close monitoring procedures 
postdose adjustment are described in Section 7.6and 
Section 7.7.  The more extensive monitoring is important 
given the elevated risk of decompensation and potential for 
higher hepatic exposure to OCA in this population. 
Investigators, together with the Sponsor’s Medical 
Monitor or designee, will consistently and frequently 
assess individual subjects, including careful 
evaluation of signs, symptoms, and laboratory 
parameters to identify potential hepatic injury 
and/or decompensation. Criteria for potential 
hepatic injury and/or progression to decompensation 
are described in Section 7.4. Criteria for 
implementing dosing adjustments, interruptions, or 
discontinuations, and close monitoring procedures 
are described in Section 7.6 and Section 7.7. 
For subjects randomized to the uptitration arm, 
special consideration is given to monitoring and 
management of investigational product as discussed 
in more detail in Section 9.2.  Uptitration criteria 
have been designed to ensure only subjects with 
evidence of adequate functional hepatic reserve will 
be exposed to the higher OCA dose (25 mg). 
Specifically, subjects may only be uptitrated at 
Month 3 if, in addition to no safety or tolerability 
concerns being identified, they meet strict laboratory 
criteria ( total bilirubin ≤1.2 mg/dL, serum albumin 
≥3.5 g/dL, INR <1.5, and platelet count 
>100,000/mm3) at both baseline and all visits prior to 
Month 3. Furthermore, uptitrated subjects must 
continue to meet those criteria throughout the study 
to stay on the uptitrated dose; if at any time a subject 
exceeds these thresholds (including upon retesting),

recommended that Investigators proactively monitor and 
manage lipid levels via appropriate medicinal interventions 
(eg, statins).  Appendix A provides a general guidance for

considered as being of childbearing potential, ie, 
fertile, following menarche and until becoming 
postmenopausal, unless permanently sterile. 
Permanent sterilization methods include 
hysterectomy, bilateral salpingectomy, and bilateral 
oophorectomy. A postmenopausal state is defined as 
no menses for 12 months without an alternative 
medical cause. A high follicle stimulating hormone 
(FSH) level in the postmenopausal range may be 
used to confirm a post-menopausal state in women 
not using hormonal contraception or hormonal 
replacement therapy. However, in the absence of 
12 months of amenorrhea, a single FSH 
measurement is insufficient.

7.5, Medical 
Management of 
Subjects with 
Symptomatic 
Cholelithiasis 
and/or 
Cholecystitis 
NA (new section added, Medical Management of 
Subjects with Symptomatic Cholelithiasis and/or 
Cholecystitis) 
NASH is associated with several known risk factors 
for cholelithiasis, such as obesity, type 2 diabetes, 
and other metabolic abnormalities. The prevalence 
of gallstone disease in NASH is higher than in the 
general population.  The majority of gallstones are 
asymptomatic and may never become symptomatic. 
Because symptomatic events of cholelithiasis and/or 
cholecystitis may develop in subjects with or 
without a known history of gallstones, it is 
important that all subjects be (1) monitored for 
signs and symptoms suggestive of gallstone disease 
and (2) counseled to recognize and seek immediate 
medical attention if they experience symptoms 
suggestive of cholelithiasis and/or cholecystitis.  
If a subject experiences symptoms suggestive of 
cholelithiasis and/or cholecystitis, s/he should 
undergo a complete evaluation consistent with the 
local standard of care, be assessed for appropriate 
treatment, including potential indication for 
surgery (e.g., cholecystectomy), and be monitored 
until resolution of clinical signs and symptoms. 
If symptomatic cholelithiasis and/or cholecystitis is 
diagnosed, IP should be interrupted (see 
Section 7.6). 
The Sponsor is 
implementing 
new rules for 
implementing and 
monitoring of IP 
in cases of 
symptomatic 
cholelithiasis 
and/or cholestasis.

Criteria 
New language added.  
Investigational product should not be 
interrupted in the following instances: 1) in 
subjects who previously experienced an event 
of symptomatic cholelithiasis and/or 
cholecystitis, and in whom symptoms have 
fully resolved at the present time while on IP; 
2) in subjects who experience an event that is 
not symptomatic (such as an incidental finding 
of gallstones during an ultrasound exam); or 3) 
in subjects who have already undergone a 
cholecystectomy following a prior event of 
cholelithiasis or cholecystitis (and who have no 
symptoms suggestive of retained or recurrent 
bile duct stones). 
The following row was added to Table 5: 
Symptomatic 
cholelithiasis

Interrupt 
Subjects who meet the  
requirements for IP  
interruption for  
symptomatic cholelithiasis  
and/or cholecystitis  
may not  
resume IP until approval  
from the Medical Monitor  
is received or further  
guidance from the Sponsor i
Subjects should remain  
in the study  
and complete all  
protocol- 
specified assessments,  
as defined in Table 1, while  
off IP. In subjects  
undergoing  
cholecystectomy following  
an event of cholelithiasis or  
cholecystitis, IP may be  
resumed after the  
procedure,  
provided there are no signs 
symptoms suggestive of  
retained or recurrent bile  
duct stones.

APPENDIX E. SUMMARY OF CHANGES:  PROTOCOL VERSION 2.0 
TO PROTOCOL VERSION 3.0 (DATED:  05 DEC 2017) 
The previous version of this protocol (747-304 Version 2.0, 17 May 2017) was amended to 
create Version 3.0 on 05 Dec 2017.  Key updates made to the protocol Version 2 are summarized 
below: 
1. The study design has been updated as follows: Subjects who meet the entry requirements 
will be randomized in a 1:1:1 ratio to one of the three treatment arms:  once daily dosing 
of OCA 10 mg, OCA 10 mg → 25 mg (ie, OCA 10 mg with uptitration to OCA 25 mg at 
Month 3), or placebo, in conjunction with local standard of care. 
2. The primary efficacy endpoint has been changed to improvement in fibrosis AND no 
worsening of Nonalcoholic Steatohepatitis (NASH). 
3. Subjects with a diagnosis of cryptogenic cirrhosis and presence of metabolic risk factor 
are no longer eligible to enroll in the study. 
4. The Introduction was revised to highlight the need for close monitoring specifically for 
patients who progress to have clinical evidence of hepatic decompensation and other 
complications due to advanced cirrhosis.  Reference is made to sections describing 
specific criteria for investigational product adjustment, interruption, or discontinuation 
based on adverse events or laboratory values. This language also emphasizes the need for 
careful observation and evaluation of the entire clinical picture over and above system-
generated alerts and flags for lab values. The importance of continued monitoring and 
appropriate referrals are highlighted in the event of potential diagnostic dilemmas and 
mandate follow-up until such dilemmas are stabilized. 
5. Guidance was added that subjects should be instructed to contact the site promptly upon 
awareness of signs and symptoms of potential hepatic decompensation such as:  pale-
colored stools, urine color from pale to deep amber [dark], nausea, vomiting, abdominal 
pain, diarrhea, weight loss, fever and chills, fatigue, weakness, loss of appetite, 
confusion, swelling of the legs or abdomen, yellowing of the skin or the whites of eyes, 
and bruising easily. 
6. Guidance was added that the Investigator should contact the study Medical Monitor upon 
awareness when any signs and symptoms of hepatic decompensation are observed in any 
subject. 
7. Pancreatitis. Subjects who are diagnosed with pancreatitis or develop symptoms 
consistent with pancreatitis, will be monitored for 3 months after the onset of symptoms 
per standard of care, including amylase and lipase enzyme levels. 
8. The visit windows for the 2 screening visits are clarified to allow for sufficient time to 
complete screening procedures.  
9. The gallbladder ultrasound will be performed at Screening to obtain baseline status.  
10. Subjects with known evidence of varices or with MELD score >12 will not be enrolled 
in the study. 
11. The duration of OLE phase is changed from 24 months to 12 months.

Synopsis, 
Methodology. 
and 
Section 7.1, Overall 
Study Design 
Up to approximately 30% of total enrolled 
subjects may have a diagnosis of cryptogenic 
cirrhosis and presence of metabolic risk factor.   
Subjects who progress to CP Class B or Class C 
during the study will discontinue investigational 
product, but should be encouraged to continue 
study visits.  
 
Double-Blind Phase (12 Months):  Subjects will 
be screened for a period of up to 8 weeks before 
entering the study.  Subjects who meet the entry 
requirements will be randomized in a 1:1 ratio to 
receive placebo or OCA daily in conjunction with 
local standard of care.  Subjects will receive OCA 
10 mg for the first 3 months.  At Month 3, all 
subjects will titrate to OCA 25 mg once daily 
unless there are safety concerns.   
Randomized subjects will be stratified by the 
presence of type 2 diabetes at enrollment (yes or 
no) and by cryptogenic cirrhosis (yes or no).   
 
 
 
Open Label Extension (up to 24 Months):  
Subjects who complete the Double-Blind Month 
12 Visit are eligible to enroll into the OLE for the 
evaluation of safety.  All subjects will receive 
OCA upon entry into the OLE.  Subjects who 
received placebo during the Double-Blind Phase 
will receive OCA 10 mg daily for 3 months and 
titrate to OCA 25 mg daily in the same manner 
that was applied during the Double Blind Phase.  
Subjects who received OCA during the Double
Blind phase will continue the same dosing 
regimen they received at the end of the Double-
Blind Phase. 
 
 
Subjects who progress to CP Class B or Class C 
during the study will discontinue investigational 
product, but are expected to be followed through 
to study closure (or at the discretion of the 
Sponsor). 
 
Double-Blind Phase (12 Months):  Subjects will 
be screened for a period of up to 12 weeks before 
entering the study.  Subjects who meet the entry 
requirements will be randomized in a 1:1:1 ratio to 
one of the three treatment arms: once daily 
dosing of OCA 10 mg, OCA 10 mg → 25 mg (ie, 
OCA 10 mg with uptitration to OCA 25 mg at 
Month 3), or placebo, in conjunction with the 
standard of care.  Uptitration will be determined 
based on the safety and tolerability assessments 
completed prior to Month 3. 
Randomized subjects will be stratified by the 
presence of type 2 diabetes at enrollment (yes or 
no).   
 
Open Label Extension (up to 12 Months):   
Subjects who complete the Double-Blind Month 12 
Visit (and continue to receive investigational 
product) are eligible to enroll into the OLE.  All 
subjects will receive OCA upon entry into the OLE.  
Subjects randomized to placebo in the Double-
Blind Phase will be re-randomized to either 
OCA 10 mg or OCA 10 mg → 25 mg (ie, OCA 
10 mg for the first 3 months of the OLE prior to 
uptitrating to OCA 25 mg at OLE Month 3).  
Uptitration will be based on the safety and 
tolerability assessments completed prior to 
Month 3.  Subjects randomized to OCA (10 mg 
or 25 mg dose) during the Double-Blind Phase will 
continue the same dosing regimen they received at 
Subjects with cryptogenic 
cirrhosis will not be 
enrolled under Version 3 of

OCA is under investigation for the treatment of 
multiple chronic liver diseases, including the 
treatment of NASH, primary biliary cirrhosis 
(PBC, also called primary biliary cholangitis 
[Beuers 2015a, Beuers 2015b, Beuers 2015c]), 
primary sclerosing cholangitis, biliary atresia, and 
other chronic liver diseases.  In May 2016, the 
United States (US) Food and Drug 
Administration (FDA) has granted accelerated 
approval for OCA (Ocaliva) for the treatment of 
PBC.  In December 2016, the European 
Medicines Agency’s Committee for Medicinal 
Products for Human Use (CHMP) approved 
conditional marketing authorization for Ocaliva 
for the treatment of PBC.

OCA is under investigation for the treatment of 
multiple chronic liver diseases, including the 
treatment of NASH, primary biliary cholangitis 
(PBC, also called primary biliary cirrhosis) [Beuers 
2015a, Beuers 2015b, Beuers 2015c]), primary 
sclerosing cholangitis, biliary atresia, and other 
chronic liver diseases.  OCA was granted 
accelerated approval by the United States Food 
and Drug Administration (FDA) on 27 May 2016.  
Conditional approvals were obtained on 12 Dec 
2016 in the European Union (EU), and by Health 
Canada on 24 May 2017 under the trademark 
Ocaliva for the treatment of PBC in combination 
with ursodeoxycholic acid (UDCA) in adults with 
an inadequate response to UDCA, or as 
monotherapy in adults unable to tolerate UDCA. 
The clinical development program for OCA in 
subjects with NAFLD or NASH includes data from 
the following 4 completed studies: 
• Double-Blind Phase of Study 747-209: A Phase 
2, double-blind, randomized, placebo-controlled, 
multicenter study evaluating the effect of OCA, 
and the subsequent addition of statin therapy, on 
lipoprotein metabolism in subjects with NASH 
with fibrosis stage 1 to 4, but no evidence of 
hepatic decompensation.  
 
Study 747-209 enrolled subjects with histological 
evidence of definite or probable NASH 
confirmed by liver biopsy and a nonalcoholic 
fatty liver disease activity score (NAS) of 4 or 
greater, randomized in a 1:1:1:1 ratio to receive 
OCA 5 mg, OCA 10 mg, OCA 25 mg or placebo, 
orally once daily, for 16 weeks.  Randomization 
was stratified by LDL concentration (fasting 
serum low-density lipoprotein (LDL) cholesterol 
at Screening Visit 2;  ≤125 mg/dL or 
>125 mg/dL) and baseline fibrosis stage (stage 1, 
2 or stage 3, 4).  Statin-free subjects as well as

In addition, 2 studies evaluating OCA for the 
treatment of NASH are currently ongoing: 
• A Phase 2, double blind, randomized, placebo
controlled study (Study 747 209) evaluating the 
effect of OCA and atorvastatin treatment on 
lipoprotein metabolism in subjects with NASH 
statin-treated subjects (following a 4-week statin 
washout) were eligible for enrollment.  All 
subjects initiated treatment with atorvastatin at 
a dose of 10 mg once daily after 4 weeks of OCA 
treatment.  After 4 weeks of 10 mg atorvastatin 
treatment, dosing was increased to 20 mg once 
daily, and continued for an additional 4 weeks.  
After 4 weeks of treatment at 20 mg daily dose, 
atorvastatin dosing could be titrated up or down 
as clinically indicated.   
A total of 84 subjects were randomized into the 
study, with baseline cirrhosis status being pre 
cirrhotic in 62 (74%) subjects and cirrhotic in 22 
(26%) subjects.  Seventy-nine (94%) subjects 
completed the Double-Blind phase.  An increase 
in LDL cholesterol was observed following 
treatment with OCA and the addition of low-
dose atorvastatin (10 mg) reversed OCA-
associated changes in LDL cholesterol back to 
baseline levels and lower within 4 weeks. 
Three subjects discontinued due to AEs: 1 
subject on OCA 5 mg for Stage 4 breast cancer, 
and 2 subjects on OCA 25 mg for pruritus. 
 
In addition, the following studies evaluating OCA 
for the treatment of NASH are currently ongoing: 
• The open label extension portion of Study 
747-209.

The incidence of NASH is increasing and NASH 
is likely to be the leading cause of liver transplant 
by 2020, highlighting the need for development 
of effective therapies that may improve 
steatohepatitis and resulting fibrosis, potentially 
delaying liver transplant or death.  
Thus, Study 747 304 will evaluate efficacy and 
safety of OCA in subjects with NASH with 
cirrhosis (defined by a NASH Clinical Research 
Network [CRN] score of 4), with the exception of 
subjects with Child Pugh (CP) score ≥7.

Doses and Duration 
Subjects will be randomized to receive OCA 
10 mg or placebo daily for the first 3 months then 
titrate to OCA 25 mg or placebo daily for the 
duration of the Double Blind Phase.   
This dose titration was selected based the known 
mechanism of FXR and on clinical experience in 
completed Phase 2 studies in subjects with 
NAFLD (747-203) and NASH (FLINT) as well 
as a clinical pharmacology study in subjects with 
hepatic impairment (Study 747-103). 
 
 
 
 
 
 
 
 
Guidelines for subjects who progress beyond CP 
Class A are provided in Section 7.5. 
In addition to placebo, two dosing regimens of 
OCA will be evaluated in this study: (1) Titration 
regimen (OCA 10 mg → 25 mg) in which OCA 
will be initiated at a dose of 10 mg once daily 
followed by uptitration to 25 mg once daily at 
Month 3; and (2) OCA 10 mg once daily for the 
entire duration of the study.  
This dose titration was selected based upon the 
known mechanism of FXR and on clinical 
experience in completed Phase 2 studies in subjects 
with NAFLD (747-203) and NASH (FLINT), as 
well as a clinical pharmacology study in subjects 
with hepatic impairment (Study 747-103). 
Study 747-209 evaluated a range of doses from 
5 mg to 25 mg in subjects with NASH and 
fibrosis, including subjects with compensated 
cirrhosis.  In this study, treatment of NASH 
subjects with compensated cirrhosis with up to 
25 mg OCA was found to be safe and well 
tolerated, and the AE profile of cirrhotic 
subjects was not different from that of 
precirrhotic subjects.  Guidelines for subjects who 
progress beyond CP Class A are provided in 
Section 7.4.

Section 5.5, Summary 
of Known Potential 
Risks with 
Investigational 
Product 
 
 The rate of progression and risk of hepatic 
decompensation is variable and may be rapid in 
certain patients, necessitating closer surveillance 
of patients at risk.  Investigators should inform 
participating subjects of known and anticipated 
risks associated with OCA treatment and 
prompt them to communicate with the 
Investigators in the event of any adverse 
experiences. 
Post-Marketing Cases of Liver Injury in PBC 
Liver injury, liver decompensation, liver failure, 
and death have been reported in patients with 
moderate to severe hepatic impairment (Child-
Pugh B and C) when Ocaliva was dosed more 
frequently than recommended in labeling for 
such patients (up to 7 times the recommended 
dose).  In addition, serious liver adverse events 
have been reported in the post-marketing setting 
in OCA-treated patients without cirrhosis or 
with mild liver impairment, both early in 
treatment and after months of treatment.  
Signs and symptoms reported in patients 
experiencing liver-related adverse outcomes who 
received Ocaliva include:  increases in bilirubin 
and other liver enzymes, new or worsening 
pruritus, new or worsening fatigue, vague 
neuropsychiatric symptoms (such as dysphoria), 
abdominal pain, nausea, vomiting, diarrhea, 
dehydration, jaundice, and liver 
decompensation. 
Clinical Study Experience 
Liver-related events 
Systemic and hepatic concentrations of OCA 
increase significantly in patients with moderate 
to severe hepatic impairment.   In PBC clinical 
studies, a dose response relationship was 
observed for the occurrence of liver related 
adverse reactions with OCA, including jaundice, 
worsening ascites, and primary biliary

Version 6.0:  06 Mar 2020

cholangitis flare with dosages of OCA 10 mg to 
50 mg once daily.  Most events occurred at a 
dose up to 5 fold higher (50 mg) than the 
maximum recommended marketed dose (10 mg).  
Clinically relevant increases in AST, ALT, or 
conjugated bilirubin (markers of liver injury) 
were rarely seen at the intended clinical doses of 
5 mg or 10 mg.  Elevated liver enzymes were 
observed in healthy subjects who were treated at 
doses ≥100 mg in Phase 1, multiple-dose studies; 
however, these elevations were only considered 
to be of clinical concern at the maximum dose of 
250 mg daily. Cases of hepatic decompensation 
cases have also occurred in PBC.  The majority 
of the cases were considered not related or 
unlikely related to investigational product by the 
Investigator.  In general, subjects who 
experienced hepatic decompensation either 
entered the study with more advanced disease, 
or for those studies where subjects started 
earlier in disease progression, events of hepatic 
decompensation generally occurred at least 
1 year after the initiation of treatment or on 
higher doses. 
Four cases of hepatic decompensation and 
potential drug induced liver injury (DILI) in the 
PBC program assessed as possibly related were 
examined by an independent hepatic 
adjudication committee.  Although the subjects 
experienced progression of liver dysfunction 
while on OCA treatment, the committee 
concluded the pattern was consistent with 
progression of underlying disease rather than a 
DILI event.      
Analyses of liver-related safety information from 
NASH subjects treated with OCA demonstrate 
an overall hepatic safety profile consistent with 
PBC.  There is no evidence to indicate a 
consistent, dose-dependent worsening of liver

Confidential and Proprietary 
biochemistries at doses up to 25 mg, including 
ALT, AST or bilirubin.  Modest increases in 
ALP levels have occurred following treatment 
with OCA, however levels were generally within 
upper limits of normal.  ALP elevations are 
generally not associated with a rise in GGT, 
suggesting that these changes are unlikely to be 
due to cholestatic liver injury.  
The incidence of liver-related adverse events in 
NASH clinical studies overall was low.  Events 
specifically reflective of hepatic decompensation 
in the NASH program was low with comparable 
incidence between OCA and placebo (2% OCA 
versus % placebo). 
Two cases of hepatic decompensation have been 
reported as SUSARs, 1 of which resulted in 
death.  In the ongoing Phase 3 clinical Study 
747-303, a NASH subject with no evidence of 
cirrhosis at baseline presented with acute liver 
injury, acute kidney injury, hyperbilirubinemia, 
and a generalized vesicular rash, which required 
hospitalization.  The Investigator assessed the 
events as severe, serious due to hospitalization, 
important medical events, and possibly related 
to the investigational product (remains blinded).  
In the ongoing Phase 2 open-label extension 
phase of Study 747-209, a NASH subject with a 
history of NASH cirrhosis with hepatic 
impairment and presumptive evidence of portal 
hypertension reported events of severe diarrhea, 
jaundice, and unintended weight loss (30 lbs in 
approximately 1 month) approximately 
5 months after initiating treatment with OCA 
25 mg; OCA was discontinued at that time.  The 
subject was subsequently hospitalized for acute 
renal failure and died due to renal failure and 
liver failure leading to cardiac arrest.  The 
Investigator assessed both the event of acute 
renal failure and the event of liver failure as fatal 

Protocol 747-304 
Version 6.0:  06 Mar 2020

Confidential and Proprietary 
in severity, serious, and unlikely related to 
investigational product. 
Pruritus 
Pruritus is an expected adverse event associated 
with OCA, particularly in subjects with 
cholestatic liver diseases such as PBC where 
pruritus is a common symptom of the disease.  In 
PBC clinical studies, the incidence of pruritus 
was 68% for OCA-treated subjects compared 
with 40% in placebo-treated subjects.  The 
majority of events have been reported as mild to 
moderate in severity and infrequently resulted in 
early discontinuation.  The majority of subject’s 
experiencing pruritus did not require an 
intervention for pruritus. The incidence and 
severity of pruritus have been shown to be dose 
dependent, but there is no evidence of 
association with stage or progression of 
underlying disease.  In NASH clinical trials, AEs 
of pruritus was reported less frequently with 
OCA treatment relative to PBC.  In the FLINT 
study, mild to moderate pruritus occurred in 
23% of OCA-treated subjects compared with 
6% of placebo-treated subjects and only 1 
subject discontinued therapy as a result of 
pruritus.    
Lipids 
In subjects with NASH (FLINT), compared to 
placebo, treatment with OCA was associated 
with statistically significant elevations in the 
mean total serum cholesterol and low-density 
lipoprotein (LDL) levels, and a decrease in the 
mean HDL, which remained within normal 
limits.  These changes developed within the first 
12-week time point after beginning of treatment, 
decreased over time after Week 12, and returned 
to baseline levels when OCA treatment was 
withdrawn.    

Protocol 747-304 
Version 6.0:  06 Mar 2020
Page 311
 
Confidential and Proprietary 
Withdrawal of OCA treatment reversed the 
OCA-induced LDL increase in all groups, 
including subjects who were not on statins 
(Neuschwander-Tetri 2015a).  In Study 747-209, 
subjects with NASH and dyslipidemia received 
placebo or OCA 5mg, 10 mg, and 25 mg once 
daily, for up to 4 weeks.  Subjects then initiated 
concurrent treatment with 10 mg atorvastatin 
once daily titrated to 20 mg once daily based on 
tolerability.  At Week 4, subjects experienced 
approximately 20% to 25% increases in LDL-C 
particles across all OCA groups.  By Week 8, 
atorvastatin treatment effectively lowered 
LDL-C to below baseline levels across all OCA 
groups compared to patients not on a statin.     
Together, the small magnitude of OCA mediated 
cholesterol and LDL changes, coupled with their 
reversibility upon cessation of OCA treatment 
and/or responsiveness to statin-initiation, suggest 
that this risk can be managed by statins as 
needed. 
An independent data monitoring committee 
(DMC) has performed detailed reviews of 
several studies including the Phase 3, clinical 
outcomes study in PBC (747-302) and the Phase 
3, pivotal study in NASH with fibrosis (747-303).  
The DMC reviewed data (unmasked for PBC 
and unblinded by treatment group for NASH 
with a total of approximately 1000 subjects) in 
closed sessions, which excluded participation of 
the Sponsor.  Based on these reviews, the DMC 
recommended that both studies continue without 
modification providing further support for the 
lack of safety concern and positive benefit-risk 
profile of OCA. 
In summary, based on the robust efficacy of 
OCA observed in PBC and NASH clinical 
studies, including improvements in liver 
biochemistry, fibrosis, and key histological

features of NASH, as well as the overall safety 
profile of OCA (in >2300 healthy subjects and 
subjects with chronic liver diseases), the benefit-
risk profile is favorable.   
Section 5.6, 
Importance of 
Monitoring of Disease 
Progression 
This is a new section added to Version 3. 
NASH is a chronic, progressive liver disease; 
therefore, it is important that subjects with 
NASH are closely monitored to ensure early 
identification of potential disease progression to 
cirrhosis, decompensation and/or liver injury.  
The rate of progression and risk of 
decompensation is variable and may be rapid in 
certain patients necessitating closer surveillance 
of patients at risk.  Therefore, more extensive 
safety monitoring and appropriate dosing 
adjustments, interruptions, and discontinuations 
will be implemented to improve subject 
oversight and safety.  Investigators together with 
the Sponsor’s Medical Monitor or designee will 
consistently and frequently assess individual 
subjects to determine on an ongoing basis the 
totality of a subject’s clinical profile, which 
includes careful evaluation of signs and 
symptoms of potential hepatic injury and/or 
decompensation coupled with rules based 
laboratory monitoring. 
Subjects will be monitored for potential hepatic 
injury and/or progression to decompensation 
(Section 7.4).  Criteria for implementing dosing 
adjustments, interruptions, or discontinuations, 
and close monitoring procedures postdose-
adjustment are described in Section 7.5 and 
Section 7.6.  The more extensive monitoring is 
important given the elevated risk of 
decompensation and potential for higher hepatic 
exposure to OCA in this population.

A subject who progresses to CP Class B or C 
cirrhosis (CP score ≥7) will discontinue 
investigational product (Section 8.2.1.1), and the 
subject should be followed for the duration of the 
study.  Subjects should be encouraged to continue 
study visits, despite stopping investigational 
product, for continued collection of safety data 
but may withdraw consent at any time. 
Monitoring of disease progression using CP score 
and MELD will be continued throughout the 
study (Table 1).  In addition, subjects should be 
re assessed within a month for disease 
progression.  At a minimum, a physical exam, 
general biochemistry, serum electrolytes, and 
assessment of CP and MELD scores should be 
conducted.  Further monitoring outside of regular 
scheduled visits should be based on the 
Investigator’s assessment of the subject’s clinical 
status. 
Section 7.4, Monitoring and Management of 
Potential Hepatic Injury and/or Disease 
Progression 
To monitor for potential hepatic injury, disease 
progression and/or hepatic decompensation, 
Child-Pugh and MELD scores will be reviewed 
at each visit (Section 7.1.2).  In addition, adverse 
events, signs and symptoms of potential hepatic 
injury or decompensation, and laboratory values 
will also be reviewed at regular intervals as 
described in the following subsections (Section 
7.4.1 to Section 7.4.3).  Based on the assessments 
of signs and symptoms of hepatic injury and

• Non-specific signs and symptoms of impaired 
health:  nausea, vomiting, abdominal pain, 
diarrhea, weight loss, fever and chills, worsening 
or new fatigue, weakness, loss of appetite 
• Significant intercurrent illnesses such as 
gastroenteritis may exacerbate hepatic injury or 
decompensation (eg, established severe 
abdominal pain, vomiting, and diarrhea for 
more than 4 days) and should be an indication 
for prompt investigational product interruption 
and complete subject evaluation

Section 7.4.2, Drug-
Induced Liver Injury 
 
Liver biochemistry will be assessed at each visit 
to assess biochemical triggers that will prompt 
an immediate reevaluation of subjects.  Thus, 
these assessments will be performed at: 
• Each protocol-specified visit 
• Unscheduled visits for any safety follow-up as 
appropriate 
It is important that the laboratory assessments 
be completed as required and that the central 
laboratory be used for assessments whenever 
possible.  In the event that a subject cannot 
return to the clinic for a scheduled or 
unscheduled visit, or there is an event that 
triggers a need for an immediate assessment, the 
use of a local lab is permissible at the discretion 
of the Investigator. In these cases, the 
investigator will obtain the laboratory results 
and the laboratory normal ranges. 
The process for assessing criteria is presented in 
Figure 2, and the specific threshold(s) for each 
laboratory analyte to trigger mandatory repeat 
testing and potentially a complete subject 
evaluation (depending on the repeat result) are 
summarized in Table 3. 
 
(Figure 2) 
 
(Table 3) 
 
If any subject meets the triggering threshold 
limits for either conjugated bilirubin or 
creatinine, investigational product should be 
immediately interrupted (see Section 7.5 for 
dosing modifications).  
For the remaining liver biochemistry 
assessments, if a subject meets the upper 
threshold limits, the laboratory assessment 
should be repeated in 2 to 3 days (with the 
Additional safety procedure

exception of ALP, which should be repeated in 
7 days).  If a repeat laboratory test cannot be 
performed within 2 to 3 days, the subject should 
be instructed to interrupt investigational 
product until repeat lab results have been 
reviewed.  
• If on repeat evaluation, values are normal or 
returned or trended back to prior values, no 
dosing modifications are required and the 
subject should continue to be monitored. 
• If on repeat evaluation, values remain above 
the specified threshold, investigational product 
should be interrupted (see Section 7.5 for dosing 
modifications).  In this case, a medical history 
and physical exam should be conducted and AE 
information (including signs and symptoms of 
liver injury as described in Section 7.4.1) 
collected.  The medical monitor should be 
promptly contacted upon awareness for 
consultation regarding management of the 
subject.  If symptoms persist or repeat testing 
shows persistent abnormality as described 
above, it is appropriate to initiate close 
observation to determine whether the 
abnormalities are improving or worsening.   
Subjects should, wherever possible, come back to 
the site.  It may be difficult for subjects who are 
distant from their study site to return to the site 
promptly.  Such subjects can have repeat (or any 
safety) laboratory tests performed at a local 
laboratory, but normal laboratory ranges and 
the results should be made available to the 
Investigator, and redacted copies provided to the 
Sponsor.  
It should be noted that it is difficult to recognize 
every potential marker of hepatic or renal 
deterioration.  There is no substitute for good 
medical judgment.  Investigators will be 
reminded to be cautious and mindful in their

evaluation of subjects’ symptoms, signs, and 
laboratory results.  However, for example, a 
single abnormal laboratory analyte result may 
be artefactual; accordingly, Investigators will be 
allowed to implement an alternate follow-up 
procedure if considered appropriate based on 
their medical judgement but only after 
documented agreement with the Sponsor’s 
medical monitor.

Scoring 
 
MELD is a scoring system used to assess the 
severity of chronic liver disease.  An increasing 
MELD score is associated with increased 
severity of hepatic dysfunction and increased 
3-month mortality risk.  MELD scores will be 
calculated based on creatinine, bilirubin, INR, 
and sodium values as appropriate, collected at 
the same visit with modification by United 
Network for Organ Sharing.  If only 1 
component of MELD needs to be repeated, all 
other components should also be repeated.  INR 
will be calculated based on PT value by the 
central laboratory.  The MELD calculation 
adjusts for subject who have had 2 or more 
dialysis treatments within the prior week and 
will automatically assign a serum creatinine of 
4.0 mg/dL for these subjects.

Section 7.4.4, Pruritus 
 
Pruritus is already being closely monitored but 
has not been shown to be a reliable predictor of

be vigilant in responding to subjects’ complaints 
of new or worsening pruritus symptoms with 
prompt follow-up.  Pruritus grading (as with all 
adverse events) should be performed in 
accordance with CTCAE Version 4.03

Section 7.6,  Close 
Observation 
 
If investigational product is interrupted or 
discontinued as described in Section 7.5, subjects 
should be closely monitored. If returning to the 
site for a scheduled visit is not feasible, use of a 
local lab may be permissible at the Investigator’s 
discretion.  Subjects who permanently 
discontinue from investigational product should 
continue regularly scheduled visits. 
At a minimum, the following assessments should 
be conducted at each study visit:   
• Physical exam and thorough review of subject 
reported signs and symptoms,  
• Liver biochemistry (including ALP, ALT, AST, 
GGT, total and conjugated bilirubin, creatinine, 
and albumin), prothrombin time (PT)/INR, 
serum electrolytes, and assessment of Child 
Pugh (only if the subject is at the study site) and 
MELD scores.  
In addition, a pharmacokinetic sample for 
assessment of OCA serum drug levels and its 
major metabolites should be obtained in any 
subject who develops an AE of hepatic injury or 
decompensation.  
For events of potential hepatic injury, the 
following additional monitoring procedures 
should be performed per FDA Guidance for 
Industry on Drug Induced Liver Injury.  These 
cases must to be discussed with the Sponsor’s 
medical monitor: 
• Repeating liver enzyme and serum bilirubin 
tests as described in Table 3.  Frequency of 
retesting can decrease to once a week or less if 
abnormalities stabilize or the study drug has 
been discontinued and the subject is 
asymptomatic, as clinically indicated.  
• Obtaining a more detailed history of symptoms 
and prior or concurrent diseases.

• Obtaining a history of concomitant drug use 
(including nonprescription medications and 
herbal and dietary supplement preparations), 
alcohol use, recreational drug use, and special 
diets is important. Concomitant drugs with 
potential hepatotoxicity should be recorded and 
discontinued unless alternative therapies are not 
available.  In the case of concomitant drugs 
potentially hepatotoxic, continued use of 
investigational product should be discussed with 
the Sponsor’s medical monitor.  The subject may 
be discontinued from investigational product, if 
clinically appropriate.  
• Obtaining a history of exposure to 
environmental chemical agents or herbal 
supplements which may be associated with liver 
toxicity.  
• Ruling out acute viral hepatitis types A, B, C, 
D (in those thought to have acute HBV 
infection), and E; autoimmune or alcoholic 
hepatitis; Wilson disease, hypoxic/ischemic 
hepatopathy; and biliary tract disease.  
• Obtaining additional tests to evaluate liver

severity using the current version of the Common 
Terminology Criteria for Adverse Events 
(CTCAE) (Section 15.1.4) and is considered 
possibly, probably, or definitely related to 
investigational product, the investigational

event has occurred leading to discontinuation 
(per discretion of the Investigator and upon 
discussion with the medical monitor). 
Refer to Section 7.4 and Section 7.5 for 
withdrawal criteria related to potential hepatic 
injury and/or decompensation; progression to 
cirrhosis with CP score ≥7; Grade 3 pruritus, 
AEs ≥Grade 3 in severity and possibly, probably,

investigational product, at least a mandatory 
interruption of investigational product is required. 
8.2.2.2. Suspected Drug Induced Liver Injury 
Cirrhotic patients have diminished liver reserve 
and lesser ability to recover, and these could 
make the consequences of a drug induced injury 
worse.  Their transaminase, especially ALT, 
levels may be normal or only slightly elevated, 
due to their lower hepatocellular reserve, even in 
advanced cases.  For this reason, relatively lower 
level of transaminase elevations can indicate 
severe drug induced liver injury and may require 
investigational product discontinuations. 
Subjects who discontinue investigational product 
are expected to be followed though to study 
closure (or at the discretion of the Sponsor) and 
should be encouraged to continue study visits 
despite stopping investigational product for 
continued study data collection but may withdraw 
consent at any time. 
Natural progression of the underlying condition 
and other causal factors such as a common bile 
duct stone or development of other concurrent 
liver disease should be considered before the 
investigational product is permanently 
discontinued.  Subjects who discontinue due to 
significant drug induced liver injury must be 
followed until the AE has resolved, stabilized, or 
is not of clinical concern. 
Investigational product must be interrupted in 
subjects if the following conditions develop:  
• Baseline values were <2x ULN, and ALT or 
AST increases to >5x baseline measurement 
(BLM). 
• Baseline values were ≥2x ULN but <5x ULN, 
and ALT or AST increases to >3x BLM. 
• Baseline values were ≥5x ULN, and ALT or 
AST increases to >2x BLM.

• ALT or AST increase >2x BLM AND the 
increase is accompanied by a concomitant total 
bilirubin increase to >2x BLM OR the INR 
concomitantly increases by >0.2. 
Investigational product will also be interrupted in 
presence of signs and symptom(s) such as rash, 
eosinophilia, nausea, vomiting, or right upper 
quadrant pain, anorexia and fatigue irrespective 
of the transaminase level, if the bilirubin is 
elevated above 2x BLM.  A potential drug
induced liver injury work up for competing 
etiologies must be performed, and a complete 
liver profile including prothrombin time 
(PT)/INR must be repeated within 48 72 hours.  
Study medication can be restarted only if an 
alternative etiology is definitively identified and 
liver tests have returned to baseline. 
Follow up procedures, including laboratory 
evaluations and physical examinations, must be 
performed after a maximum of 2 weeks of re
treatment and may be conducted at a local clinic 
if the subject is unable to return to the site. In this 
case, results as well as normal laboratory ranges, 
must be reported immediately to the site, and 
included in the case reports, so the Investigator 
can determine if the subject is to be allowed to 
continue treatment.

9.2.1. Double-Blind Phase 
Subjects randomized to the OCA 10 mg → 
25 mg arm in the Double-Blind Phase will 
receive OCA 10 mg for the first 3 months.  
Uptitration to 25 mg may occur at Month 3, 
following review of individual subject safety and 
tolerability data.   
Prior to the Month 3 study visit, the Medical 
Monitor will perform a review of consolidated 
safety data, including data from the Month 1 
and 2 study visits, as well as that from any 
unscheduled visit(s), for all study subjects.  Case 
review and discussion with the principal 
investigator will occur as needed.  A subject may 
proceed with uptitration to OCA 25 mg (or 
matching placebo), if no safety and/or 
tolerability concerns are evident in the clinical 
judgement of the reviewer(s).  The review will 
include but not be limited to the following: 
• Liver-related adverse events 
• Safety laboratories: chemistry panel including 
glucose, hematology panel, coagulation 
parameters; computed MELD score and Child-
Pugh score 
• Physical examination (development of 
clinically evident ascites or manifestations of 
hepatic encephalopathy) 
Additional considerations to determine the 
suitability to uptitrate will include an assessment 
of comorbid conditions, the subject’s overall 
adverse event profile, concomitant medications 
with a focus on potentially hepatotoxic 
concomitant medications, and/or any new 
treatment(s) for comorbid condition(s).  The 
uptitration review process is detailed in the

same manner applied in the Double-Blind Phase 
and described above.  Subjects randomized to 
OCA (10 mg or 25 mg dose) during the Double-
Blind Phase will continue the same dosing 
regimen. 
All dosing will be conducted in a dummy

This study will be conducted in a double-blind, 
placebo-controlled manner.  Enrolled subjects 
will be randomized in a 1:1 ratio to placebo or 
OCA based on a predefined randomization code 
(generated by Sponsor or designee) using an 
IWRS.  Subjects randomized to OCA will initiate 
investigational product of OCA 10 mg for 
3 months prior to uptitrating to OCA 25 mg.  
Uptitration will be based on safety and 
tolerability assessments completed at Month 1, 
Month9.2 2, and Month 3.  
Randomization of subjects will be stratified by 
the presence of type 2 diabetes at enrollment (yes 
or no) and cryptogenic cirrhosis (yes or no).   
All subjects who enroll into the OLE will receive 
OCA.  9.2Subjects randomized to placebo in the 
double-blind period will initiate investigational 
product of OCA 10 mg for the first 3 months of 
the OLE prior to uptitrating to OCA 25 mg.  
Uptitration will be based on safety and 
tolerability assessments completed at Month 1, 
Month 2, and Month 3.  Subjects will continue 
the same dosing regimen they received at the end 
of the Double-Blind Phase.   
Once all subjects have titrated to the 25 mg dose 
in the OLE, subjects may receive investigational 
product with an open label identifying the 
product as OCA 25 mg. 
9.5.1. Methods of Assigning Subjects to Treatment 
Groups 
This study will be conducted in a double-blind, 
placebo-controlled manner.  Enrolled subjects will 
be randomized in a 1:1:1 ratio to one of the three 
treatment arms: once daily dosing of OCA 
10 mg, OCA 10 mg → 25 mg (ie, OCA 10 mg 
with uptitration to OCA 25 mg at Month 3), or 
placebo.  Randomization will be done using an 
IWRS and will be based on a predefined 
randomization code generated by the Sponsor or 
designee.  Subjects randomized to OCA 10 mg → 
25 mg will initiate dosing at OCA 10 mg for 
3 months prior to uptitrating to OCA 25 mg.  
Uptitration will be based on safety and tolerability 
assessments completed prior to Month 3 
(Section 9.2). 
Randomization of subjects will be stratified by the 
presence of type 2 diabetes at enrollment (yes or 
no).   
All subjects who enroll into the OLE will receive

Section 12.2, Child-
Pugh Assessment 
The CP score is used to assess the prognosis of 
chronic liver disease, particularly cirrhosis (Pugh 
1973, Lucey 1997).  The score uses 5 clinical 
measures of liver disease (total bilirubin, serum 
albumin, PT, ascites, and hepatic 
encephalopathy), each scored 1 3, with 3 
indicating most severe.  Chronic liver disease is 
classified into CP Class A to Class C as indicated 
in Table 4.  CP score will be calculated according 
to the frequency listed in Table 1 (Double-Blind 
Phase) and Table 2 (OLE Phase).

INR = international normalized ratio 
The CP score is calculated by adding the scores 
for the 5 factors and can range from 5 15.  CP 
class is either A (a score of 5 6), B (7 9), or C (10 
or above).  Decompensation indicates cirrhosis 
with a CP score of 7 or more (Class B).  This 
level has been the accepted criterion for listing 
for liver transplantation (Pugh 1973, Lucey 
1997). 
CP score will be calculated as described in 
Section 7.4.3.1 and according to the frequency 
listed in Table 1 (Double-Blind Phase) and Table 2 
(OLE Phase).

Section 12.3, MELD 
Score 
The MELD scoring system is used to assess the 
severity of chronic liver disease.  The MELD 
score is useful in assessing patients with 
significant decompensation7.4.3.2 and the MELD 
score is now used by the United Network for 
Organ Sharing in the US and Eurotransplants to 
manage the organ allocation for liver 
transplantation.  The threshold for placement on 
an organ transplantation queue varies between 
regions across the globe, but a score of 15 results 
in a place on the transplant waiting list in the US.   
An increasing MELD score is associated with 
increased severity of hepatic dysfunction and 
increased 3 month mortality risk.  MELD scores 
will be calculated based on creatinine, bilirubin, 
INR, and sodium values as appropriate, collected 
at the same visit with modification by United 
Network for Organ Sharing.  If only 1 component 
of MELD needs to be repeated, all other 
components should also be repeated. INR will be 
calculated based on PT value by the central 
laboratory.   
MELD score will be calculated according to the 
frequency listed in Table 1 (Double-Blind Phase) 
and Table 2 (OLE Phase). 
MELD score will be calculated as described in 
Section 7.4.3.2 and according to the frequency

moved to exploratory 
endpoint because it is not a 
validated assessment and 
the magnitude of change 
that may be clinically 
meaningful is not well-
established. Therefore, this 
endpoint has been moved 
from a key secondary 
endpoint to further down in 
the hierarchy.   
Instead, improvement 
assessed using the modified 
Ishak score (adapted to 
NASH) will be moved up 
as the key secondary 
endpoint.  To ensure that a 
clinically significant 
magnitude of change is 
assessed, this endpoint will

  Methodology 
Section 7.1 
Overall Study 
Design 
This Phase 3, double-blind, randomized, placebo-
controlled, multicenter international study will evaluate the 
efficacy and safety of OCA in subjects with a biopsy-
confirmed diagnosis of cirrhosis (Ishak fibrosis score ≥5 
[incomplete, probable, or definitive cirrhosis]) due to 
NASH (or cryptogenic cirrhosis with evidence of metabolic 
syndrome) determined by central reading of liver histology.  
Subjects with hepatic decompensation or CP Class B or 
Class C cirrhosis are excluded.  All histology assessments 
will be performed centrally.   
Double-Blind Phase (12 Months):  Subjects will be 
screened for a period of up to 8 weeks before entering the 
study.  Subjects who meet the entry requirements will be 
randomized in a 1:1 ratio to receive placebo or OCA 25 mg 
daily in conjunction with local standard of care.  
Randomized subjects will be stratified by the presence of 
type 2 diabetes at enrollment (yes or no) and by Ishak 
fibrosis stage (Ishak fibrosis 5 or 6). 
Investigational product (ie, OCA or placebo) will be taken 
orally, with water, once daily.  Safety and laboratory 
assessments will be evaluated at clinical visits at Day 1, 
Month 1, and once every 3 months following the initiation 
of treatment (Day 1) through Month 12.   
Open-Label Extension (up to 24 Months):  Subjects who 
complete the Double-Blind Month 12 Visit are eligible to 
enroll into the OLE for the evaluation of safety.  All 
subjects will receive OCA upon entry into the OLE.  
Subjects will continue the same dosing regimen they 
received at the end of the Double-Blind Phase.   
This Phase 3, double-blind, randomized, 
placebo-controlled, multicenter international 
study will evaluate the efficacy and safety of 
OCA in subjects with a biopsy-confirmed 
diagnosis of cirrhosis (based on fibrosis score 
of 4 using NASH CRN scoring system) due to 
NASH determined by central reading of liver 
histology.  Up to approximately 30% of total 
enrolled subjects may have a diagnosis of 
cryptogenic cirrhosis and presence of 
metabolic risk factors.  Subjects with hepatic 
decompensation or CP Class B or Class C 
cirrhosis are excluded.  Subjects who progress 
to CP Class B or Class C during the study 
will discontinue investigational product, but 
should be encouraged to continue study visits.   
Double-Blind Phase (12 Months):  Subjects will 
be screened for a period of up to 8 weeks before 
entering the study.  Subjects who meet the entry 
requirements will be randomized in a 1:1 ratio to 
receive placebo or OCA daily in conjunction 
with local standard of care.  Subjects will 
receive OCA 10 mg for the first 3 months.  At 
Month 3, all subjects will titrate to OCA 
25 mg once daily unless there are safety 
concerns.   
Randomized subjects will be stratified by the 
presence of type 2 diabetes at enrollment (yes or 
no) and cryptogenic cirrhosis (yes or no).  
Investigational product (ie, OCA or placebo) 
will be taken orally, with water, once daily.  
Efficacy, safety and laboratory assessments will 
be evaluated at clinical visits at Day 1, monthly 
for the initial 6 months (Month 1 through 
Month 6 Visits), Month 9, and Month 12.   
 
Up to 30% of subjects with 
cryptogenic cirrhosis will 
be included in the study as 
a significant proportion of 
patients with cirrhosis due 
to NASH may lose their 
characteristic histologic 
features of NASH and may 
present as cryptogenic 
cirrhosis based on 
histopathology.   However, 
it is not known whether 
these patients will have a 
different response 
compared to those with 
clear histologic features of 
NASH, no more than 30% 
of subjects with cryptogenic 
cirrhosis will be included.    
Subjects who progress to 
Child Pugh Class B or C 
will be discontinued from 
the study as they may 
exhibit moderate to severe 
hepatic impairment, and are 
likely to result in increased 
serum concentrations of 
OCA. Since optimal dosing 
for NASH subjects with 
hepatic impairment has not 
yet been determined, these 
subjects will discontinue IP.  
The 10 mg dose titration at 
Month 3 provides adequate 
time to lower endogenous

prior to Day 1 will have a biopsy at 
Screening Visit 2.   
b During the double-blind period, all subjects 
will titrate to OCA 25 mg (or matching 
placebo) at Month 3 unless safety concerns 
dictate otherwise.  A blinded review of 
Month 1 and Month 2 safety data, 
including liver biochemistry and adverse 
events by the medical monitor will be 
conducted prior to a subject’s Month 3 
visit. 
c All subjects who enroll into the OLE will 
receive OCA.  Subjects randomized to 
placebo in the Double-Blind Phase will 
initiate investigational product of OCA 
10 mg for the first 3 months of the OLE 
prior to uptitrating to OCA 25 mg.  
Uptitration will be based on safety and 
tolerability assessments completed at 
Month 1, Month 2, and Month 3 of the 
OLE.  Subjects randomized to OCA will 
continue the same dosing regimen they 
received at the end of the Double-Blind 
Phase.   
d The study will remain blinded until all 
subjects complete the double-blind Phase.  
To maintain blinding, all placebo, OCA 
10 mg, and OCA 25 mg tablets and bottles 
will be identical.  Once all subjects have 
titrated to the 25 mg dose in the OLE, 
subjects may receive investigational 
product with an open-label identifying the 
product as OCA 25 mg.

than 12 months before Day 1 accompanied 
by TWO of the following risk factors 
− 
Obesity (body mass index ≥30 kg/m2) 
−

American Diabetes Association criteria 
(hemoglobin A1c ≥6.5%, fasting 
plasma glucose ≥126 mg/dL, 2-hour 
plasma glucose ≥200 mg/dL during oral 
glucose tolerance test, or random 
plasma glucose ≥200 mg/dL) or on any 
prescription glucose-lowering agent 
for Type 2 diabetes 
− 
Abdominal obesity (waist 
circumference >102 cm [>40 in] for 
men and >88 cm [>35 in] for women) 
with no evidence of ascites by 
imaging unless obvious on physical 
exam  
− 
Dyslipidemia (triglyceridemia 
≥150 mg/dL and low high-density 
lipoprotein [<40 mg/dL in men and 
<50 mg/dL in women]) or using a 
prescription lipid-lowering 
medication due to dyslipidemia 
 
Updated with NASH CRN 
criteria because these are 
considered more 
appropriate for the study 
population and the primary 
endpoint is based on NASH 
CRN criteria. 
The window of historic 
biopsy changed from 
6 months to 12 months 
before Day 1 because the 
NASH CRN fibrosis score 
of a cirrhotic patient is 
unlikely to improve to a 
lower fibrosis score within 
12 months, if all other entry 
criteria are met. 
The number of qualifying 
criteria for identifying 
cryptogenic cirrhosis 
subjects was increased to 
ensure the etiology of 
cryptogenic cirrhosis is 
NASH. 
Prehypertension or 
hypertension is not 
considered as part of 
qualifying criteria for 
defining cryptogenic 
cirrhosis by the FDA and 
therefore was removed.

satisfy any of the following exclusion criteria 
will be ineligible for enrollment: 
1. Current or past history of hepatic 
decompensation such as clinically 
significant ascites (requiring medical 
intervention), variceal bleeding, 
spontaneous bacterial peritonitis, hepatic 
encephalopathy (Grade I or greater based on 
West Haven classification), or 
hepatorenal/hepatopulmonary syndromes 
4. Aspartate transaminase ≥5× upper limit 
of normal (ULN) 
5. Alanine aminotransferase ≥5× ULN 
7. Platelet count ≤100000/mm3 at Screening 
11. Creatine phosphokinase >3× ULN 
28. Previous exposure to OCA within 
12 months 
The threshold of the 
exclusion criteria for AST 
and ALT were lowered to 
≥5x ULN to exclude 
subjects with significantly 
high aminotransaminases at 
study entry. 
The exclusion criterion for 
platelet counts was 
modified to ≤100000/mm3 
to further ensure subjects 
enrolled in the study are 
well compensated. 
 The exclusion criterion for 
creatine phosphokinase was 
revised to >3x ULN 
because CPK >3x ULN is 
consider too high. 
Due to limited 
hepatocellular reserve, 
cirrhotic patients might 
have advanced liver failure 
with relatively less 
elevated, even normal 
transaminase levels. For 
this reason, ALT and AST 
exclusion criteria were 
modified to exclude 
subjects with significant 
worsening of ALT and 
AST.

Rationale for 
Obeticholic 
Acid Dose and 
Duration 
Subjects will be randomized to receive OCA 25 mg or 
placebo daily during the Double-Blind Phase.   
This dose was selected based clinical experience in 
completed Phase 2 studies in subjects with NAFLD 
(747-203) and NASH (FLINT) as well as a clinical 
pharmacology study in subjects with hepatic impairment 
(Study 747-103). 
 
Subjects will be randomized to receive OCA 
10 mg or placebo daily for the first 3 months 
then titrate to OCA 25 mg or placebo daily 
for the duration of the Double-Blind Phase.   
This dose titration was selected based on the 
known mechanism of FXR and clinical 
experience in completed Phase 2 studies in 
subjects with NAFLD (747-203) and NASH 
(FLINT) as well as a clinical pharmacology 
study in subjects with hepatic impairment (Study 
747-103). 
FXR is a nuclear receptor that senses bile 
acids and regulates their intracellular levels 
in hepatocytes.  FXR activation leads to the 
reduction of intracellular bile acid levels by 
increasing the export of bile acids out of cells,

for selection of titration

thereby decreasing bile acid uptake and bile 
acid synthesis.  After 12 weeks of dosing 
OCA, FXR activation has been shown to 
reduce systemic bile acid levels while 
maintaining relatively low OCA levels in the 
total bile acid pool (<2%).  
Section 5.4.3 
Rationale for 
Obeticholic 
Acid Dose and 
Duration 
The dedicated hepatic impairment study (747-103) using 
OCA 10 mg has shown only 10% increase in the systemic 
concentrations of total OCA in subjects with CP Class A 
compared to healthy subjects.  Because a linear relationship 
from doses of OCA 5 mg up to OCA 100 mg has been 
demonstrated (Studies 747 102, 747 103, 747 105, 747
112, and 747 115), it is expected that similar systemic 
exposures of OCA 25 mg will be observed in subjects with 
CP Class A compared to noncirrhotic subjects. 
Therefore, the OCA 25 mg dose is considered appropriate 
for evaluation of safety and efficacy of OCA in all eligible 
subjects at study entry.  Guidelines for subjects who 
progress beyond CP Class A are provided in Section 7.5. 
Study duration was determined based on findings in prior 
NASH studies ranging from 6 months to 72 weeks 
The dedicated hepatic impairment study 
(747-103) using OCA 10 mg has shown only 
10% increase in the systemic concentrations of 
total OCA in subjects with CP Class A 
compared to that of healthy subjects.   
Therefore, the dose of OCA 10 mg will be 
administered for 3 months to support the 
lowering of bile acid levels in CP Class A 
subjects.  After 3 months, titration of OCA 
25 mg administration is introduced to provide 
clinically proven beneficial doses.  Guidelines 
for subjects who progress beyond CP Class A 
are provided in Section 7.6. 
The duration of the 12-week titration is based 
upon results seen in the prior PBC program 
which effectively demonstrated titration for 
biologically altering the FXR signaling 
pathways thus inducing bile acid levels.  
Overall study duration was determined based on 
findings in prior NASH studies ranging from 
6 months to 72 weeks.

upon FXR MOA and prior

Severe Drug 
Induced Liver 
Injury 
Subjects who develop severe drug induced liver injury, 
which is considered to be causally related to the 
investigational product, should be discontinued from 
investigational product and should not be rechallenged.  
Using the investigator’s clinical judgement, laboratory 
measures may be repeated for clinical confirmation.  
Subjects who discontinue investigational product are 
expected to be followed though to study closure (or at the 
discretion of the Sponsor). 
Severe drug induced liver injury is described in detail in 
Appendix B.  Natural progression of the underlying 
condition and other causal factors such as a common bile 
duct stone or development of other concurrent liver disease 
should be considered before the investigational product is 
permanently discontinued.  Subjects who discontinue due to 
significant drug induced liver injury must be followed until 
the AE has resolved, stabilized, or is not of clinical concern. 
Severe drug induced liver injury that is not considered 
related to investigational product must be discussed with 
the Sponsor before investigational product is reinitiated.  
Follow up procedures for subjects resuming treatment, 
including laboratory evaluations and physical examinations, 
must be performed after a maximum of 2 weeks of 
retreatment and may be conducted at a local clinic if the 
subject is unable to return to the site.  Results must be 
reported immediately to the site so the Investigator can 
determine if the subject is to be allowed to continue

Suspected Mild 
or Moderate 
Drug-Induced 
Liver Injury 
Because transient fluctuations of ALT or AST are common, 
and progression to severe drug induced liver injury or acute 
liver failure is uncommon, automatic discontinuation of 
investigational product with an elevation of ALT or AST 
that is >3x ULN/baseline/nadir or total bilirubin >2x 
ULN/baseline/nadir, as described in Appendix B, may be 
unnecessary.  If a subject develops signs of a mild or 
moderate event of drug induced liver injury, regardless of 
causality, investigational product should be interrupted until 
the event has resolved or returned to baseline but the 
subject should continue with the study visit schedule.  
The subject may restart treatment after resolution of the 
event or return to baseline.  Follow-up procedures, 
including laboratory evaluations and physical examinations, 
must be performed after a maximum of 2 weeks of 
re-treatment and may be conducted at a local clinic if the 
subject is unable to return to the site. 
Results must be reported immediately to the site so the 
Investigator can determine if the subject will be allowed to 
continue treatment. 
 
Cirrhotic patients have diminished liver 
reserve and lesser ability to recover, and 
these could make the consequences of a 
drug-induced injury worse.  Their 
transaminase, especially ALT, levels may be 
normal or only slightly elevated, due to their 
lower hepatocellular reserve, even in 
advanced cases.  For this reason, relatively 
lower level of transaminase elevations can 
indicate severe drug-induced liver injury and 
may require investigational product 
discontinuations.  Subjects who discontinue 
investigational product are expected to be 
followed though to study closure (or at the 
discretion of the Sponsor) and should be 
encouraged to continue study visits despite 
stopping investigational product for 
continued study data collection but may 
withdraw consent at any time. 
Natural progression of the underlying 
condition and other causal factors such as a 
common bile duct stone or development of 
other concurrent liver disease should be 
considered before the investigational product 
is permanently discontinued.  Subjects who 
discontinue due to significant drug-induced 
liver injury must be followed until the AE has 
resolved, stabilized, or is not of clinical 
concern.

Investigational product must be 
interrupted in subjects if the following 
conditions develop: Baseline values were 
<2x ULN, and ALT or AST increases to 
>5x baseline measurement (BLM). 
Cirrhotic patients have 
diminished hepatocellular 
function, lesser ability to 
recover, and may progress 
into end stage liver failure 
relatively faster. As 
mentioned above this may

into end stage liver failure 
relatively faster. As 
mentioned above this may 
result in increased serum

since optimal dosing for 
subjects with hepatic 
impairment has not yet 
been determined, these

Subjects may opt to provide blood samples for 
serial PK assessments.  Serial blood samples 
will be used to characterize the PK at steady-
state for a cohort of subjects at both OCA 10 
mg and (when titrated) 25 mg doses. An 
assessment of steady-state exposures (on an 
aggregate level) will be performed by an 
internal Intercept clinical pharmacologist/ 
pharmacometrician who is discrete from the 
study team.  These results may be made 
available to the DMC as appropriate (see 
Section 16.13).   
To best assess exposure and 
safety data across the 
duration of the trial, an 
unblinded 
pharmacometrician outside 
of the study team will 
analyze data and provide 
results to the DMC.

Specimens will undergo microbiota 16S 
ribosomal RNA gene analysis, genome 
testing, fecal metabolomics, fecal bile acid 
analysis, and other appropriate assays to 
determine if and how OCA influences the 
composition and activity of the resident 
microbiota in the gastrointestinal tract.  
Subjects will be provided kits and 
instructions for collection of stool specimens 
at home, as appropriate. 
Microbiome/metabolome analyses will be 
assessed in subjects according to the schedule 
presented in Schedule of Study Procedures 
Table 1 (Double-Blind Phase). 
Examination of microbiota 
and their metabolites in 
biopsy-confirmed cirrhotic 
subjects, as proposed in this 
study, could provide 
additional insight into 
NASH pathogenicity and 
may also potentially serve 
as a non-invasive marker of 
fibrosis. Since OCA has 
been shown to impact 
dysbiosis in animal models, 
its effect in cirrhotic 
subjects will be evaluated 
via examination of fecal gut 
microbiome, fecal 
metabolomics, and fecal 
bile acid composition.
