Methodology: 
Study Design 
This Phase 3, double-blind, randomized, long-term, placebo-controlled, multicenter international study will 
evaluate the effect of OCA on histological improvements in NASH, all-cause mortality, and liver-related clinical 
outcomes.  The study will enroll approximately 2370 subjects with NASH.  The population will comprise 
approximately 2085 subjects with biopsy-confirmed, noncirrhotic NASH and evidence of stage 2 or stage 3 liver 
fibrosis, including approximately 60% with fibrosis stage 3 and approximately 40% with fibrosis stage 2; and an 
additional cohort of approximately 285 subjects with stage 1 fibrosis with at least 1 accompanying comorbidity to 
gather information on the safety of OCA and progression of liver disease in this population.   
A planned Interim Analysis is to be performed when a minimum of 750 randomized subjects (the first sequential) 
with fibrosis stage 2 or stage 3 would have reached their actual/planned Month 18.  For the purpose of 
determining the timing of the Month 18 Interim Analysis, subjects that discontinue before their Month 18 visit 
are considered to have reached their Month 18 Visit and will be part of the Month 18 Interim Analysis cohort.  
The cutoff for the Month 18 Interim Analysis cohort database lock will be defined in the SAP.  The study will be 
continued in a blinded fashion, and subjects will be followed for clinical outcomes to confirm clinical benefit.  
Final analysis will evaluate the effect of OCA on mortality and liver-related clinical outcomes and long-term 
safety of OCA after the accrual of approximately 291 adjudicated clinical outcomes composite events combined 
in the OCA 25 mg and placebo groups for subjects with fibrosis stage 2 or stage 3 (projected to take 

Protocol 747-303 
Version 11.0: 04May2021 
Pa e 8 
approximately IO years in total). Subjects are expected to have a minimum follow-up time of approximately 
4years. 
Subjects will be screened for a period of up to 12 weeks before entering the study. Approximately 23 70 subjects 
with NASH who meet all eligibility criteria will be randomized to receive OCA IO mg, OCA 25 mg, or matching 
placebo in a I: l: I ratio for the duration of the study, in conjunction with local standard of care. Randomization 
of subjects with fibrosis stage 2 or stage 3 will be stratified by presence of type 2 diabetes at enrollment (yes/no) 
and use of thiazolidinediones (TZDs )/glitazones or vitamin E at baseline (yes/no). Biopsy-confomed NASH will 
be detennined by central reading of liver histology at Screening, and all subsequent histology assessments will be 
performed centrally in a blinded fashion. 
Investigation.al product (ie, OCA or placebo) will be taken orally, with water, once daily. Subject safety and 
laboratory assessments will be evaluated at clinical visits occuning after the first month and once every 3 months 
following the initiation of treatment (Day 1) through Month 18. Following the Month 18 visit. clinic visits will 
occur every 6 months for the remaining duration of the study. 
With the exception of liver transplant, if a subject experiences a suspected or confirmed clinical outcomes event, 
he or she should continue the regular visit schedule and continue taking i.nvestigational product as long as the 
subject has not met any of the crite1ia for discontinuation outlined in the protocol. Subjects who discontinue 
investigational product are expected to be followed through to study closure (or at the discretion of the Sponsor). 
Additional strategies to encourage continued subject paiticipation in the study will be outlined in a Subject 
Retention Plan.

Concomitant medications will be used at the discretion of the usual care provider ( or Investigator if also the us11al 
care provider). Relevant info1mation about all concomitant medications taken before (ie, within 6 months of 
Day 1) and during the study must be recorded in the. source documents and case repmt fonn, as well as any dose 
or dose regimen changes that occur during the study. To the extent possible, concomitant medications should be 
maintained at a stable dose throughout the study and at a minimum. between Day 1 and Month 18, unless the 
baseline therapy is no longer considered clinically appropriate by the Investigator. 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 providing historical biopsies to determine study eligibility should either not be taking any drugs
with potential NASH-modifying properties (specifically, TZDs/glitazones or vitamin E) or should be on a
stable dose of these medications for 6 months before Day I through Month 18. Changes to these drugs with
potential NASH-modifying prope1ties are not pennitted for the first 18 months of the study. Ideally, subjects
should generally remain on baseline TZDs/glitazones or vitarnin E from Month 18 through the end of the
study, unless the baseline therapy is no longer considered clinically appropriate by the Investigator.
•
Given the prevalence of dyslipidemia in subjects with NASH and the potential increase in total and
low-density lipoprotein cholesterol (LDLc) following treatment with OCA, it is recommended that
Investigators proactively monitor and manage lipid levels via appropriate medicinal interventions
(eg, statins). Recent guidelines stress the imp01tance of evaluating atherosclerotic cardiovascular disease
(ASCVD) risk in all patients to help guide decisions in recommending therapies and reducing LDLc to
reduce the risk and prevent onset or recwrence of ASCVD.
Prospective Surveillance: 
- screening will include a hepatobiliary ultrasound an=ha-fetoprotein assessment according to the
:dule presented in Table 1. For subjects who de, elop- during the study, llllscreening assessments for
study visits after onset of 
are not required.
Liver Histology, Event Adjudication, and Data Monitm·ing Committee Oversight: 
Central Reading of Liver Histology: All biopsy assessments will be pe1formed centrally, including assessments 
of biopsies to determine study eligibility and unscheduled biopsies. To determine eligibility at emollment 
a central pathologist must confum histological presence of NASH and a minimum NAS of 4 with a score of at 
least I in each component ofNAS. For each biopsy, key features of NASH and fibrosis sta • 
will be !?;faded in 
accordance with the NASH CRN criteria for scorin . 
einer 2005 . 
Event Adjudication: All potential liver-related clinical outcomes and potential events of hepatic injury, AKI, 
major adverse cardiovascular events (MACE), 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 (CAC): 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 including
clinical events and histological findings of potential disease progression to cilThosis
•
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 il1clude experts with relevant adjudication experience; they will not be 
ilwolved in the study as Investigators, Data Monitoring Committee (DMC) members, or consultants.

Specific details of the events that will be adjudicated by the CAC, Hepatic Outcomes Committee, HSAC, and 
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 all study sites outside of a protocol amendment. 
DMC Oversight:  An independent DMC will review all safety and efficacy data resulting from the study at 
periodic intervals.  The DMC will include hepatologists, pharmaceutical physicians, epidemiology/cardiology 
expert(s), and statistician(s); they will not be involved in the study as Investigators, adjudication committee 
members, or consultants.  All members are expected to have considerable experience with clinical study conduct 
and DMCs before joining the DMC. 
Number of Subjects (Planned): 
The study will enroll approximately 2370 subjects with NASH.  The population will comprise approximately 
2085 subjects with biopsy-confirmed, noncirrhotic NASH and evidence of stage 2 or stage 3 liver fibrosis, 
including approximately 60% with fibrosis stage 3 and approximately 40% with fibrosis stage 2; and an 
additional cohort of approximately 285 subjects with stage 1 fibrosis with at least 1 accompanying comorbidity to 
gather information on the safety of OCA and progression of liver disease in this population.  At selected 
investigational sites, approximately 300 subjects will have the option to provide blood samples for measurement 
of OCA PK concentrations.  At selected centers where the devices are available, subjects may participate in 
.  At study sites in the United States, subjects will have the 
option to provide stool samples for microbiome/metabolome analysis only if they provided baseline (Day 1) 
samples.

Statistical Methods: 
Enrnllment and Randomization 
Subjects will be randomized in a I: 1: I ratio to placebo, OCA 10 mg, or OCA 25 mg. The study will enroll 
approxilllately 2370 subjects with NASH. The population will comprise approxilllately 2085 subjects with 
biopsy-confumed, noncin·hotic NASH and evidence of stage 2 or stage 3 liver fibrosis, including approximately 
60% with fibrosis stage 3 and approxilllately 40% with fibrosis stage 2; and an additional coh01t of 
approximately 285 subjects with stage I fibrosis with at least 1 accompanying comorbidity to gather inf01mation 
on the safety of OCA and progression of liver disease in this population. 
Randomization of subjects with fibrosis stage 2 or stage 3 will be stratified by presence of type 2 diabetes at 
enrollment (yes/no) and use of TZDs/glitazones or vitamin E at baseline (yes/no). 
P1imary Analysis Populations (For· End-of-Study Analysis) 
Intent-to-Treat (ITT) Population: 
The ITr Population will include all randomized subjects with fibrosis stage 2 or stage 3 who receive at least 
1 dose of investigational product (OCA or placebo). The ITT Population will be the primaiy population used for 
efficacy analyses. Treatment assigmnent will be based on the randomized treatment. 
Full Analysis Population: 
The Full Analysis Population will include all randomized subjects, all fibrosis stages. who receive at least 1 dose 
of investigational product (OCA or placebo). Treatment assignment will be based on the randomized treatment. 
Per-Protocol (PP) Population: 
The PP Population will include all ITT 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, all fibrosis stages, 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. 
PK Population: 
The PK Population will include all OCA subjects who have at least 1 confirmed fasted analyzable sample.  
Subjects must have been fasting for approximately 8 hours before the visit and must not have any major protocol 
deviations that potentially affect exposure levels.  The PK Population will be used for OCA PK and PK/PD 
analyses. 
Additional information regarding the data cutoff date for the Month 18 Interim Analysis population will be 
defined in the SAP.  
Analyses 
Efficacy Analyses: 
All efficacy hypothesis testing will be based on the ITT population including only fibrosis stage 2 and 
stage 3 subjects.  Supportive analyses will be conducted using PP population and all fibrosis stages (Full Analysis 
Population).  
The 2-sided alpha allocated to all testing in this single study will be 0.05.  The histological endpoints will be 
tested at the Month 18 Interim Analysis with alpha level of 0.02.  The primary clinical outcomes endpoint will be 
tested with a minimum alpha level of 0.03 and this may be augmented by recycled alpha from the Month 18 
interim analysis.   
For the Month 18 Interim Analysis, multiplicity adjustment will be implemented to control the type 1 error. 
Details will be provided in the SAP. 
Primary Efficacy Analysis at the Month 18 Interim Analysis: 
The primary efficacy analysis for fibrosis improvement at Month 18 will test the following hypotheses using the 
ITT population (the ITT population for the Month 18 Interim Analysis is not the same as that for the overall study 
and is defined in the SAP): 
•
H01:  The percentage of subjects with fibrosis improvement by at least 1 stage with no worsening of NASH is
equal between placebo and OCA 25 mg.
•
H11:  The percentage of subjects with fibrosis improvement by at least 1 stage with no worsening of NASH is
different between placebo and OCA 25 mg.
The primary efficacy analysis for the resolution of NASH will test the following hypotheses: 
•
H02:  The percentage of subjects with resolution of NASH and no worsening of fibrosis is equal between
placebo and OCA 10 mg.
•
H12:  The percentage of subjects with resolution of NASH and no worsening of fibrosis is different between
placebo and OCA 10 mg.
The primary efficacy analyses at the Month 18 Interim Analysis will compare placebo and OCA using a 
Cochran–Mantel–Haenszel test stratified by the randomization strata (presence of type 2 diabetes at enrollment 
[yes/no] and use of TZDs/glitazones or vitamin E at baseline [yes/no]).  Subjects with missing histology results at 
Month 18, will be considered non-responders.  Post-baseline biopsies at early termination visit (prior to Month 
18) will be included in the analysis regardless of the timing of the biopsy.
Secondary Efficacy Analyses at the Month 18 Interim Analysis:
Histology Analysis 
Secondary efficacy endpoints at the Month 18 Interim Analysis are: 
•
Improvement of fibrosis by at least 1 stage AND/OR resolution of NASH, without worsening of either
•
No worsening of fibrosis AND no worsening of NASH

•
Percentage of subjects with improvement in each key histological feature of NASH by at least 1 point
(steatosis, lobular inflammation, and hepatocellular ballooning).
•
Percentage of subjects with improvement of fibrosis by at least 2 stages

Primary Efficacy Analysis at EOS: 
The primary efficacy endpoint at the end of the study will evaluate the effect of OCA (10 mg and 25 mg) 
compared to placebo on the clinical outcomes composite endpoint including all-cause mortality and liver-related 
clinical outcomes, as listed under the objectives for EOS section above.  Only adjudicated events will be included 
in analyses.     
The hypothesis test for the clinical outcomes composite endpoint is: 
•
H0:  The time to first occurrence of any of the adjudicated events including all-cause mortality and
liver-related clinical outcomes is equal between placebo and OCA.
•
H1:  The time to first occurrence of any of the adjudicated events including all-cause mortality and
liver-related clinical outcomes is different between placebo and OCA.
The hypothesis testing for this primary efficacy endpoint at EOS will be conducted with control of Type 1 error 
(OCA 25 mg, then 10 mg).  
Placebo and each OCA dose will be compared separately using a log rank test stratified by the randomization 
stratification factor.  The primary efficacy analyses at EOS will compare placebo and OCA, using a 
Cochran-Mantel-Haenszel (CMH) test stratified by the randomization strata (type 2 diabetes at enrollment 
[yes/no] and use of TZDs/glitazones or vitamin E at baseline [yes/no]).  The hazard ratio and 95% confidence 
interval will be determined based on a Cox regression model stratified by randomization strata to estimate the 
magnitude of the effect.   
Secondary Efficacy Analyses at EOS: 
Histology Analysis 
•
Improvement in fibrosis by 1 stage or more, with no worsening of hepatocellular ballooning, no worsening of
lobular inflammation, and no worsening of steatosis
•
NASH resolution with no worsening of fibrosis
•
Improvement of fibrosis by at least 1 stage AND/OR resolution of NASH, without worsening of either
•
No worsening of fibrosis AND no worsening of NASH
•
Percentage of subjects with improvement in each key histological feature of NASH by at least 1 point
(steatosis, lobular inflammation, and hepatocellular ballooning).
•
Percentage of subjects with improvement of fibrosis by at least 2 stages
•

•
Improvement of fibrosis and resolution of NASH as a composite endpoint and as defined by both endpoints
being met in the same subject
•
Resolution of fibrosis
Interim Analyses of Clinical Outcomes Post Month 18 Interim Analysis:
There will be 2 planned interim analyses to be conducted using group sequential approach in accordance to the 
SAP and DMC Charter at the accumulation of 50% and 80% of the total planned 291 adjudicated clinical

outcome events.  The primary efficacy endpoint for these planned interim analyses will be the clinical outcomes 
composite endpoint.  
If either of these 2 interim analyses is significant, then all analyses described in Section 16.4 will be carried out. 
Safety Analyses: 
Safety data, including TEAEs, adjudicated cardiovascular outcomes including MACE, vital signs, ECGs, and 
clinical laboratory results will compare OCA (10 mg and 25 mg) and placebo at the Month 18 Interim Analysis 
and at EOS.

INTRODUCTION
5.1. 
Overview of Nonalcoholic Steatohepatitis and Obeticholic Acid 
Nonalcoholic fatty liver disease (NAFLD) is considered to be the hepatic manifestation of the 
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 histological diseases, which progresses 
from simple steatosis to nonalcoholic steatohepatitis (NASH).  Up to one-third of these 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, 
 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).  Patients with 
NASH develop progressive fibrosis over a period of 4 to 6 years (Pagadala 2012) and 21% to 
26% of these patients develop cirrhosis in 8.2 years (Loomba 2013).  Between 38% and 45% of 
patients with NASH who have progressed to cirrhosis develop liver failure in 7 years to 10 years, 
and 2% to 5% of this population will develop 
per year 
(World Gastroenterology Organisation 2012).  Accumulating evidence suggests that patients 
with NASH can progress to 
, even in absence of apparent cirrhosis (Ertle 2011, 
Williams 2013).   
Despite the seriousness of the disease, especially when advanced fibrosis/cirrhosis is present, 
there are currently no approved pharmacologic treatments.  The current 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), although 
practice guidelines from the American Association for the Study of Liver Diseases recommend 
the use of vitamin E as first line therapy for patients with NASH without diabetes.  
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).  CDCA is the natural ligand 
for FXR, which is a nuclear receptor expressed at high levels in the liver, intestine, kidney, and 
adrenal glands.  In the liver, FXR is expressed in hepatocytes, Kupffer cells, and endothelial 
cells, and at a low level in hepatic stellate cells.  Nuclear receptors constitute a family of 
ligand-activated transcription factors that can either activate or repress a variety of target genes. 
OCA’s potent FXR agonist effects make it an attractive novel therapeutic agent for NASH due to 
its multiple FXR-mediated actions, including prevention and reversal of liver fibrosis, anti-
inflammatory effects in liver and vasculature, and hepatocyte protection against bile acid-
induced cytotoxicity (Adorini 2012, Mudaliar 2013).  Thus, there is strong rationale to advance 
OCA for the treatment of NASH.

5.2. 
Nonclinical Experience with Obeticholic Acid 
Nonclinical studies have shown several potentially beneficial properties of FXR agonism in 
NASH, including: 
Effects of OCA on 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 (Mudaliar 2013, 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 addition, OCA and other FXR agonists are anti-atherogenic and cardioprotective in
animal models (Miyazaki-Anzai 2010, Hartman 2009).
Anti-inflammatory and anti-fibrotic effects of OCA: 
•
OCA exerts direct effects on serum-starved LX2 cells (an immortalized hepatic
stellate cell line) to reduce the expression of key fibrotic genes (collagen I, alpha-1
smooth muscle actin, transforming growth factor β-1 and matrix metalloproteinases)
(Albanis 2005).
•
In primary and cultured hepatocytes treated with pro-inflammatory mediators, OCA
exerted direct effects to inhibit pro-inflammatory gene expression (eg, tumor necrosis
factor-α [TNF- α], cyclooxygenase-2, and inducible nitric oxide synthase)
(Wang 2008).
•
FXR activation (with WAY-362450) reduced inflammatory cell infiltration and
hepatic fibrosis in a mouse model of NASH (Zhang 2009).
•
OCA improves portal hypertension in cirrhosis models (Mookerjee 2015).
•
OCA inhibits gastrointestinal inflammation and preserves intestinal barrier function
in models of inflammatory bowel diseases (Gadaleta 2011).
In summary, there is strong rationale to advance OCA for the treatment of NASH based on its 
FXR-mediated hepatoprotective properties and results indicating that OCA improves glycemia 
by increasing peripheral glucose uptake, enhances glucose-stimulated insulin secretion, and 
inhibits hepatic lipid synthesis and content while inducing lipid uptake by adipocytes.

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), primary sclerosing cholangitis (PSC), 
biliary atresia, and other chronic liver diseases.  Ocaliva has received marketing authorization in 
the United States, Europe, and Canada 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.  Please see the approved, region-specific 
labeling for more information including its specific marketing requirements. 
The clinical development program for OCA in subjects with NAFLD or NASH includes data 
from the following 3 studies, as well as 1 ongoing study with no data available yet: 
•
Study 747-203:  A proof-of-concept, Phase 2 study in subjects with type 2 diabetes
and 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.
•
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, placebo-controlled study investigating the effect of OCA
and atorvastatin treatment on lipoprotein metabolism in subjects with 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 pruritus general) 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 subjects from Study 747-203 
withdrew from the study due to pruritus.   
The FLINT study demonstrated that OCA 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 that OCA was superior to placebo in improving fibrosis, a 
strong predictor of liver-related death.  OCA treatment was also associated with improvement in 
markers of hepatocellular injury and some cardiometabolic features, including weight and 
systolic blood pressure.  Salutary effects on weight and blood pressure are important 
considerations since patients with NASH present with higher cardiovascular risk given the 
comorbidities of obesity and diabetes.  On average, low-density lipoprotein (LDL) cholesterol 
demonstrated a modest but significant increase in subjects treated with OCA compared to 
placebo; however, this increase was reversed and LDL cholesterol returned to below baseline 
levels in subjects who initiated statin therapy.  The change 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.

Version 11.0: 04May2021

The general adverse event (AE) profile was similar across both 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).  The number of pruritus-associated 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 LDL 
metabolism in subjects with NASH to better understand the lipid profile changes observed in the 
FLINT study.  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 10 mg atorvastatin 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 low-
density lipoprotein cholesterol (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. 
5.4. 
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 has become one of the leading 
causes of liver transplant (Wong 2020, Younossi 2020), highlighting the need for development 
of effective therapies that can improve steatohepatitis and resulting fibrosis, potentially delaying 
liver transplant or death.  In the FLINT study, OCA demonstrated statistically significant 
improvements over placebo in all individual features of steatohepatitis as well as fibrosis 
(Neuschwander-Tetri 2015) and merits further evaluation in a larger study.   
Given the slow natural history of progression for NASH, assessing clinical endpoints is a 
long-term endeavor.  Hence, Study 747-303 is designed to initially assess efficacy based on a 
surrogate endpoint to support a regulatory filing, and subsequently confirm the ability of OCA to 
confer clinical benefit over placebo.   
Enriching the population for Study 747-303 with a mix of subjects with more advanced and 
aggressive disease states serves to enroll subjects with the greatest unmet need and at highest risk 

Protocol 747-303 
Version 11.0: 04May2021

Confidential and Proprietary 
of disease progression, and increases the likelihood of accruing outcomes to confirm clinical 
benefit in a reasonable time frame. 
5.4.1. 
Rationale for Placebo Control Group 
The use of a randomized placebo control group added to established standard of care 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.  Notably, accounting for the standard of care effect is critical 
when designing an outcome-based study conducted globally when there are regional differences 
in the treatment of subjects with NASH. 
5.4.2. 
Rationale for OCA Dose 
The dose of 25 mg was chosen based on prior studies in subjects with NAFLD and NASH 
(Study 747-203 and FLINT).  In Study 747-203, 64 subjects with type 2 diabetes and NAFLD 
were treated with placebo, OCA 25 mg or OCA 50 mg for 6 weeks.  Both doses were similarly 
efficacious.  Only mild constipation was seen more frequently in the 50 mg OCA group (24%) 
than the 25 mg OCA and placebo groups (0% each) in this 6-week, proof-of-concept study. 
The subsequent, Phase 2 randomized, double-blind FLINT study evaluated OCA 25 mg and 
placebo in subjects with NASH over 72 weeks.  While OCA was well-tolerated overall, there 
was an increased incidence of mostly mild or moderate pruritus in OCA-treated subjects 
compared to placebo-treated subjects.  Pruritus was also the most common AE associated with 
OCA in PBC studies, and has been shown to be dose related, warranting 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 the proposed NASH study in addition to the 25 mg dose. 
5.5. 
Summary of Known Potential Risks with Investigational Product 
The primary AE shown to be related to OCA is pruritus.  Pruritus has also been observed in 
clinical studies with OCA in other indications, as well as in healthy subjects, with the highest 
frequency observed in subjects with PBC.  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. 
The rate of progression and risk of decompensation is variable and may be rapid in certain 
patients, necessitating closer surveillance of patients at risk.  Recent safety findings in NASH 
clinical trials include 9 cases of hepatic decompensation 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 an SAE of variceal bleed, hepatic encephalopathy, 
or spontaneous bacterial peritonitis.  The fatal case was reported in a subject with cirrhosis and 
hepatic impairment at baseline; the subject was in the OCA 25 mg treatment group.

Version 11.0: 04May2021

Key liver-related findings: 
•
eDISH analyses show no evidence of hepatic injury with OCA compared to placebo.
•
In PBC, hepatic AEs evaluated by Standardized MedDRA criteria showed a rate of
hepatic AEs higher in OCA-treated subjects compared with those treated with
placebo.  In NASH clinical trials, the incidence of hepatic TEAEs was similar
between OCA and placebo groups.  Serious hepatic TEAEs, however, occurred more
frequently with OCA 25 mg, as compared to OCA 10 mg and placebo
•
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 Classification.  While 1.5- and 1.7-fold increases in liver
concentrations of OCA are predicted for subjects with Child-Pugh Class B and C,
respectively, liver concentrations of OCA in subjects with Child-Pugh A are predicted
to be similar to those of healthy control subjects (1.1-fold increase).  In a hepatic
impairment study in NASH subjects with compensated 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).
•
Serious liver-related adverse reactions have been reported in postmarketing in PBC
patients with decompensated cirrhosis or Child-Pugh Class B or C hepatic
impairment when Ocaliva was dosed more frequently than the recommended starting
dosage of 5 mg once weekly.
OCA-related changes in serum lipids (decrease in high-density lipoprotein cholesterol [HDLc] 
and increase in LDLc) have been observed in healthy volunteers, in subjects with PBC and 
NASH, and in subjects with other underlying conditions.  However, the pattern and magnitude, 
as well as the clinical significance of these changes, are not well understood and clearly depend 
on a subject’s underlying condition and other comorbidities.  Although increases in LDLc have 
generally been considered to be associated with increased cardiovascular risk, it is not possible to 
draw conclusions regarding the cardiovascular effect of OCA-related changes in lipid profile 
given the concurrent positive effects of OCA on other metabolic factors such as a decrease in 
hs-CRP (in PBC studies), and relative improvement of triglyceride and very low-density 
lipoprotein (VLDL) cholesterol levels.  In order to better assess cardiovascular risk, longer 
treatment periods and larger numbers of subjects are necessary and are being studied further.   
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 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. 
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: 
•
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. 
Refer to the IB 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; 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 subjects necessitating closer surveillance of subjects 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 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 decompensation and progression to 
cirrhosis (Section 7.4).  Criteria for implementing dosing adjustments, interruptions, or 
discontinuations, and close monitoring procedures postdose-adjustment are described in 
Section 7.4.3 and 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.

INVESTIGATIONAL PLAN
7.1. 
Overall Study Design
This Phase 3, double-blind, randomized, long-term, placebo-controlled, multicenter 
international study will evaluate the effect of OCA on histological improvements in NASH, 
all-cause mortality, and liver-related clinical outcomes.  The study will enroll approximately 
2370 subjects with NASH.  The population will comprise approximately 2085 subjects with 
biopsy-confirmed, noncirrhotic NASH and evidence of stage 2 or stage 3 liver fibrosis, including 

Protocol 747-303 
Version 11.0: 04May2021
Page 42
Confidential and Proprietary 
approximately 60% with fibrosis stage 3 and approximately 40% with fibrosis stage 2; and an 
additional cohort of approximately 285 subjects with stage 1 fibrosis with at least 
1 accompanying comorbidity to gather information on the safety of OCA and progression of 
liver disease in this population.  
A planned Interim Analysis is to be performed when a minimum of 750 randomized subjects (the 
first sequential) with fibrosis stage 2 or stage 3 would have reached their actual/planned 
Month 18 Visit.  For the purpose of determining the timing of the Month 18 Interim Analysis, 
subjects that discontinue before their Month 18 visit are considered to have reached their 
Month 18 Visit and will be part of the Month 18 Interim Analysis cohort.  The cutoff for the 
Month 18 Interim Analysis cohort database lock will be defined in the SAP.  The study will be 
continued in a blinded fashion, and subjects will be followed for clinical outcomes to confirm 
clinical benefit.  Final analysis will evaluate the effect of OCA on mortality and liver-related 
clinical outcomes and long-term safety of OCA after the accrual of approximately 
291 adjudicated clinical outcomes composite events combined in the OCA 25 mg and placebo 
groups for subjects with fibrosis stage 2 or stage 3 (projected to take approximately 10 years in 
total).  Subjects are expected to have a minimum follow-up time of approximately 4 years.   
Subjects will be screened for a period of up to 12 weeks before entering the study.  
Approximately 2370 subjects with NASH who meet all eligibility criteria will be randomized to 
receive OCA 10 mg, OCA 25 mg, or matching placebo in a 1:1:1 ratio for the duration of the 
study, in conjunction with local standard of care.  Randomization of subjects with fibrosis 
stage 2 or stage 3 will be stratified by presence of type 2 diabetes at enrollment (yes/no) and use 
of thiazolidinediones (TZDs)/glitazones or vitamin E at baseline (yes/no).  Biopsy-confirmed 
NASH will be determined by central reading of liver histology at Screening, and all subsequent 
histology assessments will be performed centrally in a blinded fashion.  
Investigational product (ie, OCA or placebo) will be taken orally, with water, once daily.  
Subject safety and laboratory assessments will be evaluated at clinical visits occurring after the 
first month and once every 3 months following the initiation of treatment (Day 1) through 
Month 18.  Following the Month 18 visit, clinic visits will occur every 6 months for the 
remaining duration of the study. 
With the exception of liver transplant, if a subject experiences a suspected or confirmed clinical 
outcomes event, he or she should continue the regular visit schedule and continue taking 
investigational product as long as the subject has not met any of the criteria for discontinuation 
outlined in Section 7.7.  Subjects who discontinue investigational product are expected to be 
followed through to study closure (or at the discretion of the Sponsor).  Specific strategies to 
encourage continued subject participation in the study will be outlined in a Subject Retention 
Plan (Section 7.9).

7.1.3. 
Study Duration 
The overall study duration is event driven and will be determined by the time required to achieve 
approximately 291 adjudicated events for the clinical outcomes composite endpoint in the OCA 
25 mg and placebo groups combined for subjects with fibrosis stage 2 and stage 3, estimated to 
take approximately 10 years.   
7.2. 
Number of Subjects 
The study will enroll approximately 2370 subjects with NASH.  The population will comprise 
approximately 2085 subjects with biopsy-confirmed, noncirrhotic NASH and evidence of stage 2 
or stage 3 liver fibrosis, including approximately 60% with fibrosis stage 3 and approximately 
40% with fibrosis stage 2; and an additional cohort of approximately 285 subjects with stage 1 
fibrosis with at least 1 accompanying comorbidity to gather information on the safety of OCA 
and progression of liver disease in this population. 
At selected investigational sites, approximately 300 subjects will have the option to provide 
blood samples for measurement of OCA PK concentrations.  At selected centers where the 
devices are available, subjects may participate in 
measurements.  At study sites in the United States, subjects will have the option to provide stool 
samples for microbiome/metabolome analysis only if they provided baseline (Day 1) samples. 
7.3. 
Treatment Assignment 
Subjects will be randomized in a 1:1:1 ratio to receive placebo, OCA 10 mg, or OCA 25 mg 
(in a blinded manner) from Day 1 through study termination. 
7.4. 
Monitoring and Management of Potential Hepatic Injury and/or 
Decompensation 
AEs, signs and symptoms of potential hepatic injury or decompensation, and laboratory values 
will be reviewed at regular intervals as described in the following subsections (Section 7.4.1 to 
Section 7.4.2.1).  Based on the assessments of signs and symptoms of hepatic injury 
(Appendix C) and liver biochemistry, investigational product will be continued, interrupted, or 
discontinued per criteria discussed in Section 7.7, and close monitoring procedures will be 
implemented (refer to Section 7.4.3).  
In the event of a potential hepatic injury, the subject should be promptly brought into the clinic to 
undergo a complete evaluation including laboratory assessments, physical examinations, and 
review of signs and symptoms of potential hepatic injury or decompensation.   
The Investigator will educate each subject about recognizing the signs and symptoms of hepatic 
injury or decompensation and instruct each subject to contact the study site to report the onset of 
any of the 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. 
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: 
•
Worsening or new pruritus
•
Decreased urine output, dizziness, or lethargy
Healthcare Provider (HCP) Interactions will be reported: 
•
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 (refer to Section 9.3)
•
Laboratory procedures or assessments performed by an HCP
Signs and symptoms of potential hepatic injury or decompensation should be followed by 
(1) evaluation of liver biochemistry for potential drug-induced liver injury (DILI)
(Section 7.4.1), (2) assessment for disease progression to cirrhosis (Section 7.4.2), (3) triggering
of investigational product interruption or discontinuation per criteria (Section 7.7),
(4) documentation in the AE eCRF or the SAE eCRFs (Section 15.1.5 and Section 15.1.6), and
(5) contact with the medical monitor.
7.4.1. 
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 16.11.  The specific criteria for 
identification and adjudication of potential hepatic injury events are described in the HSAC 
charter.

Liver biochemistries will be evaluated 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 in the event of signs or symptoms of potential hepatic injury,
decompensation, or if laboratory alerts have been triggered
It is important that the laboratory assessments be completed as required and that the central 
laboratory be used for assessments whenever possible.  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.  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 subjects using specific 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 2.

If any subject meets the triggering threshold limits indicated in Table 2 and experiences signs or 
symptoms of hepatic injury (severe fatigue, nausea, vomiting, right upper quadrant pain, fever, 
rash, eosinophilia) investigational product should be immediately interrupted (see Section 7.7 for 
dosing modifications). 
If no signs or symptoms of hepatic injury 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 2.  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, the 
Medical Monitor should be promptly contacted upon awareness for consultation regarding 
management of the subject. 
•
If on repeat evaluation, 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 2),
investigational product must be interrupted for a minimum of 30 days, a PK sample
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 in whom close monitoring is initiated, a follow-up assessment of the subject’s 
status should be performed after approximately 12 months of monitoring. 
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.  The 
original or copies should be retained at the site as the source documents.  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 or may clearly be 
explained for a particular subject as due to pre-existing conditions or circumstances unrelated to 
their liver function or the study; accordingly, Investigators may be allowed to implement an 
alternate follow-up procedure, based on their medical judgement, but only after documented 
consultation and 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.  
7.4.2. 
Progression of Disease to Cirrhosis 
Investigators will closely monitor subjects for potential progression to cirrhosis at every visit (or 
at unscheduled visits).  If the subject meets one or more of the criteria for potential progression 
to cirrhosis described in Figure 3 and/or any additional evidence that may be available including 
findings from targeted physical exams or from clinically indicated procedures (eg, biopsy, 
ultrasound, or esophagogastroduodenoscopy [EGD]), then the subject is considered to have 
potentially progressed to cirrhosis; Child-Pugh scores must then be assessed.  Refer to 
Section 7.4.2.1 for determination of Child Pugh Score.  If a subject may have progressed to 
cirrhosis, a Fibroscan assessment should be performed where possible (if not already part of the 
scheduled assessment) and repeated annually.  Dose adjustments or investigational product 
discontinuation may be required in subjects who meet criteria for progression to cirrhosis (see 
Table 4).  If the dose of investigational product is adjusted (Child-Pugh A) or if investigational 
product is discontinued (Child-Pugh B or C) a PK sample must be collected within 7 days.  The 
PK sample should be collected prior to receiving the reduced dose. 
If non-invasive indicators of progression to cirrhosis become evident at any time during the 
study, it is recommended that a liver biopsy should be obtained and sent for central reading to 
confirm the diagnosis of cirrhosis and for inclusion in the analysis of study outcomes.  Any 
interpretations by a local pathologist should be collected and entered in the eCRF within 2 days 
of receiving results.  If a biopsy is not performed, the reason should be stated in the eCRF.  The 
following clinical outcomes may preclude the need for a liver biopsy to confirm progression to 
cirrhosis:  presence of ascites, hepatic encephalopathy, variceal hemorrhage, or the presence of 
large esophageal varices or varices with a red wale that require treatment. 
The process for assessing disease progression to cirrhosis, the potential need for liver biopsy, and 
the implications on dosing are summarized in Figure 3.  
Potential events of progression to cirrhosis will be reviewed and adjudicated by the Hepatic 
Outcomes Committee which is described in Section 16.11.  The Hepatic Outcomes Committee

a It is not necessary to rule out the occurrence of varices, ascites, or hepatic encephalopathy at each visit; however, if at any time 
during the clinical management of the subject there are signs and symptoms that are suggestive of any of these events (eg, 
ascites noted on ultrasound or presence of varices noted on clinically indicated EGD), then the subject is considered to have met 
the criteria for progression to cirrhosis and a Child-Pugh screen must be assessed for that subject. 
7.4.2.1. 
Child-Pugh Assessment 
The Child-Pugh (CP) Score (Pugh 1973, Lucey 1997) will be assessed only in subjects who meet 
one or more of the criteria for progression to cirrhosis (Figure 3).  A targeted examination will be 
performed to assess ascites and hepatic encephalopathy.  CP is calculated and reported within the 
electronic data capture (EDC) system based on data entered into the eCRF by adding the scores 
from the 5 factors outlined in Table 3 and can range from 5-15.  Among subjects who meet 
criteria for progression to cirrhosis, dose adjustment (see Table 4) should be considered in those

with a CP score <7, and investigational product should be discontinued in those with a CP 
score ≥7.  For the purpose of dose adjustment or discontinuation, Child Pugh Scores should 
ONLY be applied in subjects who demonstrate progression to cirrhosis based on criteria 
presented in Section 7.4.2.  Dose adjustment or discontinuation should not be considered based 
solely on the CP score, in subjects who do not meet criteria for progression to cirrhosis.  
Calculation of the CP score includes Investigator assessments of ascites and hepatic 
encephalopathy, which may be assessed during the AE review at the scheduled visits, as well as 
total bilirubin, serum albumin, and prothrombin time, which will populate from the central 
laboratory.  The relationship of CP Score to disease progression is as follows: 
•
CP Score 5-6 = mild, well compensated disease (ie, CP Class A)
•
CP Score 7-9 = moderate, significant functional compromise (ie, CP Class B)
•
CP Score ≥10 = severe, decompensated disease (ie, 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.  The MELD score 
is calculated using serum creatinine (mg/dL), bilirubin (mg/dL), and INR.  The MELD-Na score 
is calculated using serum creatinine (mg/dL), bilirubin (mg/dL), INR, and sodium and is 
calculated when the MELD score is greater than 11.  The MELD calculation adjusts for subjects 
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.

7.4.3. 
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 
disease progression to cirrhosis or 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 of the clinical event leading to discontinuation has occurred 
(per discretion of the Investigator and upon discussion with the Medical Monitor). 
At a minimum, the following assessments should be conducted at each study visit:  
•
Exam and thorough review of subject-reported signs and symptoms of hepatic injury
or decompensation (Appendix C)
•
Liver biochemistry (including ALP, ALT, AST, GGT, total and conjugated bilirubin,
creatinine, and albumin), prothrombin time (PT)/INR, serum electrolytes, and
assessment of algorithm for progression to cirrhosis (only if the subject is at the study
site) and MELD scores
In addition, a PK 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 or 
interrupts investigational product due to potential hepatic injury (Section 7.4.1).  A PK sample 
should also be collected when the dose of investigational product is reduced (Child-Pugh A) or 
discontinued (Child-Pugh B/C) due to progression to cirrhosis (Section 7.4.2).  
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 need to 
be discussed with the Sponsor’s Medical Monitor: 
•
Repeating liver enzyme and serum bilirubin tests as described in Table 2
•
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 that are 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 that may be associated with liver toxicity

Protocol 747-303 
Version 11.0: 04May2021

Confidential and Proprietary 
•
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’s disease,
hypoxic/ischemic hepatopathy; and biliary tract disease
•
Obtaining additional tests to evaluate liver function, as appropriate (eg, INR, direct
bilirubin)
•
Seeking hepatology consultation, if the Investigator is not a hepatologist
For all subjects in whom close monitoring is initiated for potential hepatic injury, a follow-up 
assessment of the subject’s status should be performed after approximately 12 months of 
monitoring. 
7.4.4. 
Pruritus 
Pruritus is to be closely monitored.  Although pruritus itself has not been shown to be a predictor 
of hepatic injury, Investigators should be vigilant in responding to subjects’ complaints of new or 
worsening pruritus symptoms with prompt follow-up.  Pruritus grading (as with all AEs) should 
be performed in accordance with the current version of the CTCAE (Appendix D). 
For subjects with Grade 3 pruritus per the current version of the CTCAE (Section 15.1.5.1), 
instruct the subject to discontinue investigational product (Table 4).  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 pruritus ≤ Grade 2 is provided in Table 4 and Section 15.1.5.1. 
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 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, or fever 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, 
decreased 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 estimated glomerular filtration rate (eGFR).  All local laboratory 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 4.

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.   
Figure 4: 
Algorithm for Monitoring Subjects for Potential Renal Impairment 
ACE = angiotensin converting enzyme; AE = adverse event; ARBs = angiotensin receptor blockers; BUN = blood 
urea nitrogen; eCRF = electronic case report form; eGFR = estimated glomerular filtration rate; IP = investigational 
product; NSAIDS = nonsteroidal anti-inflammatory drugs. 
a Baseline value is defined as the average of the two most recent serum creatinine values from study visits 
(scheduled and unscheduled) that are at least 7 days apart and are not associated with an acute event or creatinine 
increase.  Elevated results due to a renal-related AE or transient use of a nephrotoxic medication should not be 
included in the baseline calculations. 
b Laboratory assessments include:  serum chemistry (creatinine, albumin, BUN, electrolytes), urinalysis with 
microscopic examination, and assessment of eGFR.  
c Evaluation should be comprehensive and include assessments of recent medical history, changes in health status, 
changes in medications (especially ACE inhibitors, ARBs, NSAIDs, diuretics), and intercurrent illness. 
d 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 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 16.11).  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 with 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 (evidence of hematuria, flank or lower abdominal pain, nausea, vomiting, fever, 
or chills).  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 

Protocol 747-303 
Version 11.0: 04May2021

Confidential and Proprietary 
(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.   
7.7. 
Investigational Product Adjustment, Interruption, and 
Discontinuation Criteria 
Dosages for investigational product should be maintained constant during the study.  However, 
adjustments, interruptions, discontinuation, and any rechallenge of investigational product should 
be implemented per the criteria outlined in Table 4. 
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.  The Investigator should use their clinical judgement to determine if
more frequent assessments of laboratory tests and symptoms are necessary.
•
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.  The Investigator should use their clinical judgement to determine if more
frequent assessments of laboratory tests and symptoms are necessary until
stabilization of the clinical event leading to discontinuation has occurred (per
discretion of the Investigator and upon discussion with the medical monitor
[Section 7.4.3]).  The subjects will not be rechallenged with investigational product.
Subjects who interrupt treatment will be monitored to determine if or when investigational 
product may be restarted.  However, an interruption of investigational product may result in 
treatment discontinuation.  In this instance, an EOT or EOS visit should occur only after 
discussion of the event with the sponsor’s medical monitor.  The investigator should obtain a 
liver biopsy at the EOT visit to characterize any histological changes during the period that the 
subject was taking 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 if the interval from the last 
visit was more than 3 months (+2 weeks) during the first 18 months of the study or more than 
6 months prior (+2 weeks) during the remainder of the study. 
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 investigational product; 2) in subjects 
who experience an event that is not symptomatic (such as an incidental finding of gallstones 
during an ultrasound exam); 3) in subjects who have already undergone a cholecystectomy 
following a prior event of cholelithiasis or cholecystitis (and who have no symptoms suggestive

7.8. 
Criteria for Study Termination 
The Sponsor reserves the right to tenninate the study at any time. It is normal procedme 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 necessaiy to stop the study before all 
subjects have completed the study. In addition, the Sponsor may terminate the study at an 
investigation.al site at any time (eg, Good Clinical Practice [GCP] noncompliance or 
poorly performing sites, as determined by the number of subjects emolled 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 inf01med by the Sponsor as to when the final study visit is to be completed 
and should then schedule all subjects for the EOS or EOT Visit. The window of time for 
scheduling the visit will be based on a final projection of when the requisite 291 adjudicated

events will have been accrued in the OCA 25 mg and placebo groups combined for subjects with 
fibrosis stage 2 or stage 3. 
7.9. 
Subject Retention 
The primary objectives for the end of study analysis are to evaluate the effects of OCA compared 
with placebo on all-cause mortality and liver-related clinical outcomes.  The overall study 
duration is event driven and will be determined by the time required to observe the prespecified 
adjudicated events for the clinical outcomes composite endpoint (Section 7.8).  Therefore, it is 
very important that subjects continue to participate for the duration of the study to enable 
assessment of clinical outcomes.  
Subjects may discontinue investigational product during the study; however, these subjects are 
expected to continue in the study until study termination and every effort will be made by the 
investigator to discuss subjects’ continuation in the study.  Investigators will emphasize to 
subjects the importance of their continuation in the study after withdrawal of investigational 
product by either continuing to attend regularly scheduled visits, allowing semi-annual telephone 
visits by the investigator, or by allowing the investigator to have continued access to the 
subjects’ medical records to assess potential major adverse cardiovascular events (MACE) and 
liver-related clinical outcomes.  The site staff will encourage subjects to adopt an option that 
allows for the most data moving forward.  Subjects will be asked to provide both personal and 
primary physician(s) contact information who can provide information to the investigator about 
the clinical/medical status on the subjects’ behalf.  Additional information is described in 
Section 8.2.1.  
Please refer to specific strategies and procedures that will provide additional information to 
facilitate subject retention as described in a separate Subject Retention Plan.

Bariatric Surgery (Gastric Bypass) 
Subjects must discontinue investigational product after undergoing bariatric surgery.  A liver 
biopsy should be obtained at the time of surgery.  Subjects should be encouraged to continue 
study visits, despite stopping investigational product, for continued study data collection but may 
withdraw consent at any time. 
8.2.1. 
Other Reasons for Discontinuation of Investigational Product 
Subjects who discontinue investigational product are expected to continue in the study until the 
end of the study or at the discretion of the Sponsor.  With the exception of liver transplant, if a 
subject experiences a suspected or confirmed 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 termination of the 
study need to also continue to follow the regular visit schedule through to study closure.  In 
general, subjects should be strongly encouraged to both stay on investigational product and 
remain in the study until study termination.  Specific strategies to encourage continued subject 
participation in the study will be outlined in a Subject Retention Plan.  Early termination 
procedures should only be conducted if the subject withdraws consent (see Section 9.9.9). 
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.
•
The occurrence of clinical or laboratory AEs considered by the Investigator to be
clinically important.
•
Modification of consent:
−
Consent may be modified to discontinue study visits but allow semi-annual
telephone contact of subject, 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 or semi-annual telephone contact
but allow continued access to medical records to assess for potential major adverse
cardiovascular events (MACE) and liver-related clinical outcomes
•
Withdrawal of consent:
−
Consent may be fully withdrawn
The Investigator must notify the Medical Monitor as soon as possible when a decision to 
discontinue a subject from treatment is made or when any subject prematurely withdraws from 
the study.

8.2.2. 
Withdrawal of Consent and Requirements to Re-Enter the Study 
Withdrawal of Consent 
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 must be recorded in the appropriate CRF. 
Requirements to Re-enter Study after Withdrawal of Consent 
Subjects who withdraw consent and want to re-enter the study must confirm that they have not 
received any investigational product being evaluated for the treatment of diabetes, weight loss, or 
NASH within 30 days before restarting investigational product or within 5 half-lives of the 
compound (whichever was longer) before restarting investigational product.  Subjects are to be 
re-consented and new baseline visit procedures must be performed if the interval from the last 
visit was more than 3 months (+2 weeks) during the first 18 months of the study or more than 
6 months prior (+2 weeks) during the remainder of the study. 
8.2.3. 
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. 
A reasonable effort must be made to contact the subject and determine the reason(s) why a 
subject fails to return for a study visit or is lost to follow-up, as outlined in the Subject Retention 
Plan.  This information and date of contact must be recorded in the appropriate CRF. 
8.2.4. 
Subject Discontinuation Notification 
The Investigator must notify the Medical Monitor by telephone or email as soon as possible if 
any subject prematurely withdraws from the study.  The date when the subject is withdrawn and 
the reason for discontinuation must be recorded in the CRF.  If a subject is “lost to follow-up” 
(fails to return for a visit), a reasonable effort should be made to contact the subject in order to 
determine why the subject failed to return.  This information must be documented in the CRF.  If 
a subject is withdrawn from the study early (regardless of the cause), all of the EOT/EOS 
evaluations should be performed at the time of withdrawal, as appropriate (see Section 9.9.9).  
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, and OCA 25 mg.  Each dose 
will be made up of 1 tablet (ie, one placebo tablet, one OCA 10 mg tablet, or one OCA 25 mg 
tablet). 

Protocol 747-303 
Version 11.0: 04May2021
Page 74
Confidential and Proprietary 
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. 
For subjects participating in the PK portion of the study:  All assessments, except for the 
post-dose collection of blood samples for the subset of subjects participating in the PK 
assessment, must be completed before administration of investigational product. 
Refer to Section 7.7 and Table 4 for adjustments, interruptions, and discontinuation of 
investigational product per safety criteria. 
9.2. 
Lifestyle Modification Counseling 
Despite the serious nature of the disease, there are currently no approved therapies for the 
treatment of NASH nor accepted standard of care.  The therapeutic options for NASH are largely 
limited to lifestyle modifications, generally encompassing diet and physical activity, and 
treatment of concurrent conditions such as type 2 diabetes, obesity, hypertension, and 
dyslipidemia.  Lifestyle modifications can be very effective in patients who make significant 
adjustments to their lifestyle.  Therefore, in accordance with the current standard of care, all 
subjects will receive counseling on lifestyle modification with regard to diet and exercise.  
Owing to the regional and cultural differences in diet and lifestyle across investigational sites, 
Investigators will be asked to counsel subjects on ways to maintain a healthy diet and to 
encourage subjects to engage in an appropriate form of exercise. 
9.3. 
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 6 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.  To the extent possible, concomitant medications should be maintained at a stable dose 
throughout the study and at a minimum, between Day 1 and Month 18, unless the baseline 
therapy is no longer considered clinically appropriate by the Investigator.  In general, 
Investigators will be encouraged to follow guidelines for care based upon local and institutional 
practice patterns and any relevant published practice guidelines. 

Protocol 747-303 
Version 11.0: 04May2021
Page 75
Confidential and Proprietary 
Exceptions to this general requirement are noted below. 
•
Subjects providing historical biopsies to determine study eligibility should either not
be taking any drugs with potential NASH-modifying properties (specifically,
TZDs/glitazones or vitamin E) or should be on a stable dose of these medications for
6 months before Day 1 through Month 18.  Changes to these drugs with potential
NASH-modifying properties are not permitted, for all subjects, for the first 18 months
of the study.  Ideally, subjects should generally remain on baseline TZDs/glitazones
or vitamin E from Month 18 through the end of the study, unless the baseline therapy
is no longer considered clinically appropriate by the Investigator.
9.3.1. 
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 sequestrants) 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 15.1.5.1. 
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.   
9.3.2. 
Other Concomitant Medications 
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 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. 
If non-invasive indicators of progression to cirrhosis become evident at any time during the 
study, it is recommended that a liver biopsy should be obtained and sent for central reading (refer 
to Section 7.4.2). 
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). 
9.3.3. 
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 participants as indicated via appropriate 
medicinal interventions (eg, statins).  Recent guidelines stress the importance of evaluating 
atherosclerotic cardiovascular disease (ASCVD) risk in all patients to help guide decisions in 
recommending therapies and reducing LDLc to reduce the risk and prevent onset or recurrence 

Protocol 747-303 
Version 11.0: 04May2021
Page 76
Confidential and Proprietary 
of ASCVD.  As such, reducing lipids, particularly low-density lipoproteins, are part of a 
comprehensive cardiovascular 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 5).

9.3.4. 
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 the 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 an endocrinologist if 
they experience new onset type 2 diabetes mellitus. 
9.4. 
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.  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. 
9.5. 
Randomization and Blinding 
This study will be conducted in a double-blind, placebo-controlled manner.  Subjects will be 
randomized 1:1:1 to placebo, OCA 10 mg, or OCA 25 mg.  Randomization of subjects with 
fibrosis stage 2 or stage 3 will be stratified by presence of type 2 diabetes at enrollment (yes/no) 
and use of TZDs/glitazones or vitamin E at baseline (yes/no).  The randomization will be based 

Protocol 747-303 
Version 11.0: 04May2021
Page 78
Confidential and Proprietary 
on a predefined randomization code (generated by the Sponsor or designee) using an interactive 
web response system (IWRS), which the Sponsor intends will serve as a computer-based subject 
registration system at Screening and Day 1.  The IWRS will serve as an investigational product 
inventory and management system and may be integrated with the study database.  
The Investigator or designee will be required to register the subject in the IWRS and may be 
prompted to provide subject data necessary to properly randomize and allocate the subject to 
treatment.  A randomization number will be assigned and investigational product dispensing 
information (ie, bottle number[s]) will be provided.   
The Sponsor will have access to aggregate event rates (blinded) to perform sample size 
re-estimation, but will remain blinded to actual adjudicated outcomes throughout the entire study 
until the final analysis or intervention. 
Data flow, access, process and disclosure of unblinded data will be described in a data access 
plan (DAP) in order to preserve the integrity of the final analysis of the ongoing study.   
9.5.1. 
Emergency Unblinding Procedures 
Randomization codes and corresponding treatment assignment will be made available to the 
Investigator and the Medical Monitor for emergency use only through the IWRS 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 blinded 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 in the subject’s 
source record and should subsequently contact the Medical Monitor to explain any premature 
unblinding of treatment assignment (such as accidental unblinding or unblinding due to a serious 
adverse event [SAE]).  Procedures for unblinding a subject’s treatment will be provided 
separately to the Investigator.  The Medical Monitor will document within study correspondence 
the rationale, circumstances, and the person or persons being informed about the unblinding.   
The DMC (refer to Section 16.10) will be provided unblinded data to review during closed 
sessions.  The DMC will document, in the closed session DMC minutes (which will be made 
available to the Sponsor only after the database is locked and the study is unblinded), details 
about any unblinded subject data reviews.  Cases of premature unblinding (as noted above) will 
be reviewed by the DMC. 
Access to randomization codes and corresponding treatment assignment will also be made 
available through the IWRS system to the appropriate, named individual(s) responsible for 
unblinding suspected unexpected serious adverse reactions (SUSARs) for reporting to the 
Regulatory Authorities. 
9.6. 
Assignment of Site and Subject Numbers 
9.6.1. 
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 CRF.

9.6.2. 
Subject Numbers 
Subjects will be identified by a unique 6-digit number, independent of the randomization 
number.  The first 3 digits will represent the site number and the last 3 digits will represent the 
Screening number. 
9.7. 
Restrictions 
No additional restrictions. 
9.8. 
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 
747-303 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.
•
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).
9.9. 
Visit Procedures
9.9.1. 
Visit Windows
Visits should be based on Day 1 (not on the prior visit) unless stated otherwise.  For example, 
Month 3 should ideally occur 3 months (±2 weeks) following Day 1.  A month is defined as 
4 weeks (ie, 28 days).  The visit windows are as follows:

100 days from previous visit during the first 18 months of treatment, an unscheduled bottle 
should be proactively dispensed and provided to the subject. 
9.9.2. 
Informed Consent Procedures 
The Investigator or designee will explain the nature, purpose, possible risk and benefit of the 
study to the subject and will provide him/her with a copy of the written info1mation and 
informed consent f01m (ICF). The subject will be given sufficient time to consider the study 
before deciding whether or not to pa1iicipate. The subject will be infonned that paiiicipation is 
voluntaiy and that her/his future medical treatment will not be compromised by pa1ticipation 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 inf01med 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 the written information and 
his/her signed and dated consent f mm.

9.9.3. 
Screening Visit Procedures (.12 weeks before Day 1) 
An initial Screening Visit must be perfo1med :::12 weeks before Day 1 to dete1mine 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 emolled 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 to confnm that early rescreening will not affect safety or efficacy for the subject. 
For rescreening, all Screening procedures should be repeated and a new 3-digit Screening 
number assigned. Subjects should be re-consented, as appropriate, at this time. 
Subjects will be emailed in the study when info1med consent is obtained. Screening Visit 1 
procedures for all subjects are as follows: 
•

Subjects who discontinue investigational product are expected to continue in the study until the 
end of the study or at the discretion of the Sponsor.  Additional strategies to encourage continued 
subjects participation in the study will be outlined in a Subject Retention Plan.   
EOT procedures will be required whenever subjects discontinue treatment with investigational 
product.  The EOT visit and procedures listed below must be performed as close as possible to 
the subject’s last dose of investigational product.  When a subject discontinues investigational 
product but continues with regularly scheduled study visits, the EOS visit will be completed later

in the study as the subject’s final study visit.  The actual investigational product discontinuation 
scenario (Table 6) will determine the sequence of the EOT and EOS visits and procedures.  In 
some cases, the EOT visit and procedures will precede the EOS visit; in others, the EOT and 
EOS visits will be combined and performed as close as possible to the subject’s last dose of 
investigational product.   
When a subject ends her/his participation in the study (eg, at a point between standard study 
visits) either due to early termination (withdrawal of consent) or discontinuation, an EOT/EOS 
visit must be performed as near as possible to her/his last dose of investigational product and the 
procedures, listed below, performed.  The purpose of this visit is to conduct complete and/or 
final assessments on or as near as possible to the final day of dosing.  In some cases, the subject 
may discontinue on the day of a scheduled study visit.  In these cases, EOT/EOS visit procedures 
should be performed in place of the scheduled study visit procedures.  The data will be recorded 
as EOT and EOS procedures in the CRF.

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 
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 within 2 days of
receiving results.  Note:  Investigational product can only be dispensed if central or
local laboratory values are available.

Minimum testing required to support the protocol:  Liver safety labs of direct and
total bilirubin, AST, ALT, GGT, ALP, coagulation panel (INR, aPTT), platelets,

albumin and serum creatinine and non-liver safety labs of CBC & Diff, standard 
electrolytes, lipid panel 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.
•
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 the 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 the pediatric population suffering from 
biliary atresia (BA), there are no safety data available specific to 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, vaccine name, and 
manufacturer should be recorded as a concomitant medication for each dose.

INVESTIGATIONAL PRODUCT MATERIALS AND
MANAGEMENT
11.1. 
Investigational Product 
The investigational product is a white, round, film-coated tablet containing 25 mg or 10 mg of 
OCA or placebo.  All tablets are identical in size and appearance.  The tablets contain the 
following inactive ingredients:  microcrystalline cellulose, sodium starch glycolate, and 
magnesium stearate.  The OCA 25 mg tablet also contains silicon dioxide. 
11.2. 
Investigational Product Packaging and Labeling 
The packaging and labeling of investigational product supplies will be performed according to 
Good Manufacturing Practice standards by a designated qualified vendor.  All investigational 
product will be provided as tablets for oral administration and provided in high-density 
polyethylene bottles with heat induction seals and child resistant closures.  The bottle packaging 
will not reveal any information about the treatment dose contained in the bottle.  Multiple bottles 
may be dispensed to the subject according to the visit schedule in Table 1 to provide enough 
tablets for daily dosing until the next time drug is dispensed.  If a known visit schedule departure 
is planned for a time frame greater than 100 days from previous visit during the first 18 months 
of treatment, an unscheduled bottle should be proactively dispensed and provided to the subject. 
The designated investigational product packaging/distribution vendor will also be responsible for 
the distribution of the investigational product to the clinical sites. 
11.3. 
Investigational Product Storage 
All OCA tablet strengths provided to clinical trial sites in support of clinical study are to be 
shipped and stored at 15°C to 25°C.  Temperature excursions within the range of 2°C and 30°C 
for no more than a 6 month period are acceptable, and the OCA tablet continues to be suitable 
for use in clinical studies.  Additionally, temperature excursions within the range -20°C to 40°C 
for no more than 7 days are acceptable, and the OCA tablet continues to be suitable for use in 
clinical studies.  
11.4. 
Investigational Product Administration 
Refer to Section 9.1. 
11.5. 
Investigational Product Accountability and Disposal 
The Sponsor’s representative will send investigational product to the study site under appropriate 
storage conditions.  All shipments of investigational product should be unpacked and the 
contents reviewed immediately upon receipt.  If it is not possible to verify the contents 
immediately, they must be stored under the appropriate storage conditions until verification of 
the contents is possible (ideally, within 1 business day from receipt).  The pharmacist or designee 
should verify the investigational product against the shipment documentation.  The pharmacist or 
designee should contact the Sponsor immediately to report any concerns regarding the shipment.  

Protocol 747-303 
Version 11.0: 04May2021

All investigational product will be provided for use only in this study and is not to be used for 
any other purpose. The Investigator or designee will maintain a full record of investigational 
product accountability, including records of individual subject dispensing and final return or 
disposition (as directed by the Sponsor). 
The study monitor, also known as the Clinical Research Associate (CRA) will review 
accountability records against investigational product dispensed and that remaining in stock, 
during on site monitoring visits and when the study is completed, or if it is prematurely 
tenninated. The CRA will retrieve documentation detailing and confinning the return or 
destruction of the investigational product. If the investigational product is to be returned to the 
Sponsor's vendor for destruction, the CRA will also prepare the investigational product for 
shipment.

ASSESSMENTS OF EFFICACY
13.1. 
Liver Biopsies 
T = aspartate 
Given that historical biopsies are to be obtained no more than 6 months before Day 1, slides 
should be sent for centrnl reading at least 4 weeks before the end of the 6-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 
speǶ manual. Liver biopsies are to be performed after the hepatobiliaiy ultrasound 
for __ If the initial biopsy was obtained from the left lobe, then subsequent 
biopsies must be obtained from the left lobe. Biopsies should be at least 2 cm in length. If a 
serial liver biopsy is required, the biopsy should not be perfo1med within 6 months of a prior 
liver biopsy, unless clinically indicated. For subjects who develop potential liver-related clinical 
outcomes during the study, protocol-specified biopsies for study visits after onset of the potential 
outcome event may not be required.

The investigator will assess the clinical criteria for progression of fibrosis to cirrhosis for each 
subject during the study.  If non-invasive indicators of progression to cirrhosis become evident at 
any time during the study, it is recommended that a liver biopsy should be obtained and sent for 
central reading.  Updated guidance on criteria to trigger an unscheduled liver biopsy in subjects 
with potential progression to cirrhosis may be provided to investigators separately. 
If possible, a PK blood sample should be collected at the time of the liver biopsy. 
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 biopsy assessments will be performed centrally, including assessments from biopsies to 
determine study eligibility and unscheduled biopsies, and biopsies that may be performed to 
confirm cirrhosis according to criteria described in Section 7.4.2. 
To determine eligibility at enrollment, a central pathologist must confirm histological presence 
of NASH and a minimum NAS of 4 with a score of at least 1 in each component of NAS.  For 
each biopsy, key features of NASH (ie, steatosis, lobular inflammation, and hepatocellular 
ballooning) and fibrosis staging will be graded in accordance with the NASH CRN criteria for 
scoring (Kleiner 2005) as summarized in Table 7.

Subjects Who Develop Cirrhosis and Child-Pugh Class A 
Subjects who develop cirrhosis and are Child-Pugh Class A (CP score <7) will have their dose 
adjusted (refer to Table 4).  These subjects will provide 1 blood sample for PK assessment prior 
to dose adjustment, at the next scheduled visit.  The PK assessment will measure serum 
concentrations of OCA, its conjugates (glyco-OCA and tauro-OCA), and OCA-glucuronide.  The 
time of the last dose of investigational product and the time of the last meal will be recorded.  
The subject will then begin taking the adjusted dose of investigational product, thereafter, at the

ASSESSMENTS OF SAFETY
15.1. 
Adverse Events and Serious Adverse Events 
15.1.1. 
Definition of Adverse Events 
15.1.1.1. Adverse Event 
An AE is 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 as 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 if they develop any of the signs and 
symptoms of intercurrent illness and/or potential adverse events listed in Appendix C.  
15.1.1.2. Treatment-Emergent Adverse Event 
A treatment-emergent AE (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. 
15.1.1.3. 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-subject hospitalization or prolongation of existing hospitalization
•
Results in persistent or significant disability or incapacity
•
Results in a congenital abnormality or birth defect

Protocol 747-303 
Version 11.0: 04May2021
Page 111
Confidential and Proprietary 
•
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 a 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 will be recorded in the eCRF.  If a PK sample cannot be 
collected within 7 days, the reason should be recorded in the eCRF. 
15.1.2. 
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. 
15.1.3. 
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,” “possible” or “probable,” the event will be considered to be related to the 
investigational product for the purposes of expedited regulatory reporting.

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.

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 10, must be entered on the AE CRF.  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 current version of the CTCAE 
manual for guidance on appropriate grading.

15.1.5.1. Severity of Pruritus (as an AE) 
To ensure consistency in reporting, pruritus AEs must be graded for severity (ie, intensity) using 
the current version of the CTCAE (Appendix D) the category definitions are included in 
Table 11 for reference.  As pruritus is a subjective symptom, clinical judgment should be used to 
determine its management.   
Table 11: 
Severity of Pruritus 
Pruritus Grade 
Clinical Description of Severity for Pruritus 
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, the occurrence and magnitude of which are not readily 
measured objectively, 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.  Guidance for 
the management of subjects experiencing significant pruritus are provided in Table 4 
(Section 7.7) and includes: 
•
Pruritus ≥Grade 3 in severity:  Discontinue investigational product
•
Pruritus ≤Grade 2 in severity:  One or more of the following may be considered:
−
Drug holiday or less frequent dosing at the discretion of the Investigator.
−
Short-term use of BAS

Protocol 747-303 
Version 11.0: 04May2021
Page 114
Confidential and Proprietary 
•
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.
•
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 9.3.
−
Other medical therapies may be considered, as deemed clinically appropriate and
based on current practice guidelines (EASL 2017) or literature (Hegade 2015).
15.1.6. 
Reporting of Adverse Events and Serious Adverse Events 
15.1.6.1. 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 CRF.  Each AE is to be evaluated for 
duration, intensity, frequency, seriousness, outcome, other actions taken, and relationship to the 
investigational product.  Redacted medical record source documentation will be requested for all 
SAEs and emergency room visits. 
In addition, the Investigator should contact the study Medical Monitor promptly when any signs 
or symptoms of hepatic decompensation are observed in any subject. 
15.1.6.2. 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 must be reported to the Sponsor (including potential liver-related clinical outcome 
events that qualify as serious).   

Protocol 747-303 
Version 11.0: 04May2021
Page 115
Confidential and Proprietary 
SAEs are reported by entering the SAE data into the study specific 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 be reported by: 
If an SAE is reported by 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
•
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 faxed to 
 or 
emailed to 
 as 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. 
SAEs involving potential liver-related clinical outcome events will be processed and reported by 
the Sponsor as described in Section 15.1.7.  
15.1.7. 
Potential Liver-Related Clinical Outcome Events 
Specified liver-related clinical outcome events may, by definition (see Section 15.1.1.3) qualify 
as SAEs.  The Sponsor must be notified of any SAEs within 24 hours of the site becoming aware 
of the event (see Section 15.1.6.2).  The Sponsor is responsible for regulatory reporting of SAEs, 
including expeditious reporting of SUSARs, refer to Section 15.1.2 for definition of SUSAR.  
Given that the liver-related clinical outcome events could also meet the criteria of a SUSAR, 
which would necessitate unblinding for expedited reporting, the Sponsor will not expeditiously 
report potential liver-related clinical outcome events in order to retain the study blind and 
preserve the integrity of the clinical outcomes endpoint.  These events will be selected as a 

Protocol 747-303 
Version 11.0: 04May2021
Page 116
Confidential and Proprietary 
“study event” on the Adverse Event CRF and will be submitted for adjudication to the Hepatic 
Outcomes Committee as described in Section 16.11. 
The Sponsor will consider the following list of clinical outcome events (MedDRA preferred 
terms) to be disease related and exempt from expeditious regulatory reporting, but will continue 
to report them in a non-expeditious manner:  death, end-stage liver disease (preferred term: 
chronic hepatic failure), liver transplant (preferred term: liver transplant), 
, variceal bleeding (preferred terms: gastroesophageal variceal 
haemorrhage, esophageal varices haemorrhage), hepatic encephalopathy (preferred term: hepatic 
encephalopathy), spontaneous bacterial peritonitis (preferred term: peritonitis bacterial), ascites 
secondary to cirrhosis (preferred term: ascites), and progression to cirrhosis (preferred term: 
hepatic cirrhosis). 
15.1.8. 
Additional Investigator Responsibilities for SAEs 
The safety data recorded in the CRF 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 CRF.  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. 
15.1.9. 
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 15.1.6.2. 
15.1.10. 
Notification of Post-Study SAEs 
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 15.1.6.2. 
All SAEs that occur within 30 days of discontinuation from the study, whether or not they are 
related to investigational product, should be reported to the Sponsor within 24 hours by 
following the instructions provided in Section 15.1.6.2. 
15.1.11. 
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.  

Protocol 747-303 
Version 11.0: 04May2021
Page 117
Confidential and Proprietary 
If resolved, a resolution date for the AE should be documented on the CRF.  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 CRF.  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 cholelithiasis 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. 
15.1.12. 
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 (see Table 4) and the Sponsor must be notified within 
24 hours of the Investigator’s awareness of the pregnancy by completing the Pregnancy CRF in 
the EDC system and downloading and completing the Pregnancy Report Form.  The Pregnancy 
Report Form must be emailed to 
.  The 
subject and neonate must be followed for outcome information and/or as considered appropriate 
by the Investigator and the Sponsor. 
The subject may re-start investigational product when she is no longer pregnant or breastfeeding 
at the discretion of the Investigator and after discussion with the Medical Monitor.  The subject 
must have a negative pregnancy test before restarting investigational product.  If a subject’s 
pregnancy is terminated early (planned or unplanned), she must have termination of the 
pregnancy confirmed by a serum β-hCG test before restarting investigational product. 
Completing the Pregnancy Report Form 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 15.1.6 must also be followed.

Other Safety Parameters 
15.2.1. 
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, 
gender, race, and ethnicity) will be recorded. 
15.2.2. 
Physical Examination 
To assess for clinical findings, the Investigator or designee will perform a physical examination 
at the visits specified in Table 1.  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 CRF page.   
15.2.3. 
Vital Signs 
Vital signs will be assessed at the visits specified in Table 1.  Vital signs include body 
temperature, sitting heart rate, respiratory rate, and sitting blood pressure.  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.   
15.2.4. 
Electrocardiogram 
Standard 12-lead ECGs will be collected at the visits specified in Table 1.  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 CRF as normal, abnormal but not clinically 
significant, or abnormal and clinically significant.  Any clinically significant abnormality on 
ECGs should be reported on the AE CRF 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.
15.2.5. 
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 using the AUDIT, smoking habits, and 
caffeine consumption CRFs.  AUDIT is a 10-item questionnaire that uses the domains of alcohol 
consumption, drinking behavior, and alcohol-related problems (Saunders 1993) 
15.2.6. 
Laboratory Assessments 
Except for Screening and safety lab visits between regularly scheduled visits, 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 CRF.  If the subject reports having eaten (water is 
permitted) within 8 hours, the Investigator or designee will document accordingly in the source 

Protocol 747-303 
Version 11.0: 04May2021 
Page 119 
and CRF and remind the subject that fasting is required before all regularly scheduled study 
visits after screening ( exception - safety lab visits). 
Blood, urine, and stool samples for laborat01y assessments will be collected at the visits specified 
in Table 1. Full instrnctions 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 separate procedural manuals. All necessaiy collection supplies will 
be provided by the appropriate laborato1y 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 laborat01y is required. In 
these cases, the Investigator will obtain the laborat01y results and the laborat01y n01mal ranges. 
All local laborat01y data, including the reference ranges, ai·e to be collected and entered in the 
eCRF within 2 days ofreceiving 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 laborat01y tests containing clinically significant abnormal values ai·e to be 
followed regularly until the values return to n01mal ranges· until a valid reason, other than 
investigational product-related AE is identified; or until further follow-up is deemed medically 
unnecessaiy.

evaluating ASCVD risk in all subjects to help guide decisions in recommending therapies and 
reducing LDLc to reduce the risk and prevent onset or recmTence of ASCVD (refer to 
Section 9.3.3 and Appendix A). 
Urine-based ͘-hCG pregnancy tests will be perfmmed for female subjects of childbearing 
potential at the visits specified in Table 1. If a mine pregnancy test is positive, a se1um 
pregnancy test must be perfo1med to confom the result. If positive the Sponsor must be notified 
and the subject will be followed, as outlined in Section 15.1.12 through pregnancy outcome. 
International normalized ratio (INR) will be calculated based on prothrombin time value by the 
central laborato1y. MELD scores will be calculated based on creatinine, bilirnbin, INR, and 
sodium values as appropriate, collected at the same visit, with modification by United Network 
for Organ Sharing. If only I component of MELD needs to be repeated, all other components 
should also be repeated. Homeostatic model assessment-insulin resistance (HOMA-IR) values 
will be calculated based on glucose and insulin concentrations. Total OCA will be calculated 
based on OCA, tam-o-OCA, and glyco-OCA concentrations. Laboratory analyte results may be 
used to calculate various cardiovascular risk and fibrosis measw·ement scores.

Primary Analysis Populations (For End-of-Study Analysis) 
The following subject populations will be evaluated and used for presentation and analysis of the 
data: 
•
The Intent-to-Treat (ITT) Population will include all randomized subjects with
fibrosis stage 2 or stage 3 who receive at least 1 dose of investigational product (OCA
or placebo).  The ITT Population will be the primary population used for efficacy
analyses.  Treatment assignment will be based on the randomized treatment.
•
The Full Analysis Population will include all randomized subjects, all fibrosis stages,
who receive at least 1 dose of investigational product (OCA or placebo).  Treatment
assignment will be based on the randomized treatment.
•
The Per-Protocol (PP) Population will include all ITT subjects who do not have any
major protocol violations that potentially affect the efficacy conclusions.  Treatment
assignment will be based on the randomized treatment.
•
The Safety Population will include all randomized subjects, all fibrosis stages, 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.
•
The PK Population will include all OCA subjects who have at least 1 confirmed
fasted analyzable sample.  Subjects must have been fasting for approximately 8 hours
before the visit and must not have any major protocol deviations that potentially
affect exposure levels.  The PK Population will be used for OCA PK and PK/PD
analyses.
Additional details regarding the cutoff for the Month 18 Interim Analysis population will be 
defined in the SAP.

Efficacy Analysis at Month 18 Interim Analysis 
16.3.1. 
Primary Efficacy Analysis 
All efficacy analysis will be conducted using the ITT population (only including fibrosis stage 2 
and stage 3 subjects).  The hypothesis testing of primary and (key) secondary endpoints will be 
conducted with control of Type 1 error (OCA 25 mg, then 10 mg).  The 2-sided alpha allocated 
to all testing in this single study will be 0.05.  The histological endpoints will be tested at the 
Month 18 Interim Analysis with an alpha level of 0.02.  The primary clinical outcomes endpoint 
will be tested with a minimum alpha level of 0.03, and this may be augmented by recycled alpha 
from the Month 18 Interim Analysis.  Adjustments for multiplicity are specified in Section 16.7, 
and additional details on the testing will be provided in the SAP. 
The primary endpoints at the Month 18 Interim Analysis are: 
•
Improvement in fibrosis by 1 stage or more, with no worsening of hepatocellular
ballooning, no worsening of lobular inflammation and no worsening of steatosis
•
NASH resolution with no worsening of fibrosis
The primary efficacy analysis for fibrosis improvement at the Month 18 Interim Analysis will 
test the following hypotheses using the ITT population (the ITT population for the Month 18 
Interim Analysis is not the same as that for the overall study and is defined in the SAP): 
•
H01:  The percentage of subjects with fibrosis improvement by 1 stage or more, no
worsening of hepatocellular ballooning, and no worsening lobular inflammation is
equal between placebo and OCA.
•
H11:  The percentage of subjects with fibrosis improvement by 1 stage or more, no
worsening of hepatocellular ballooning, and no worsening lobular inflammation is
different between placebo and OCA.
The primary efficacy analysis for the resolution of NASH with no worsening of fibrosis at 
Month 18 Interim Analysis will test the following hypotheses using the ITT population: 
•
H02:  The percentage of subjects with NASH resolution and no worsening of fibrosis
is equal between placebo and OCA.
•
H12:  The percentage of subjects with NASH resolution and no worsening of fibrosis
is different between placebo and OCA.
NASH resolution is defined as the overall histopathological interpretation of 1) “no fatty 
liver disease” or 2) “fatty liver disease [simple or isolated steatosis] without steatohepatitis” 
AND a NAS of 0 for ballooning and 0-1 for inflammation.  The primary efficacy analyses at 
the Month 18 Interim Analysis will compare placebo and OCA using a 
Cochran-Mantel-Haenszel (CMH) test stratified by the randomization strata (type 2 diabetes 
at enrollment [yes/no] and use of TZDs/glitazones or vitamin E at baseline [yes/no]).   
Supportive analyses will be conducted using PP population and all fibrosis stages (Full Analysis 
Population).  Additional supportive and sensitivity analyses along with analysis populations of 
interest will be defined in the SAP.

16.3.2.2. Liver Biochemistry and Liver Function 
The following laboratory parameters will be summarized by treatment group:  ALT, AST, 
gamma-glutamyl transferase (GGT), ALP, total and direct bilirubin, albumin, INR, and platelets. 
Analyses of change from baseline and percent change from baseline will be performed as 
specified in the SAP. 
Descriptive statistics of the laboratory values will be summarized by treatment group and visit.  
The results, change from baseline, and percentage change from baseline values as well as 
estimates of least-square (LS) means, standard errors, and 95% confidence intervals (CIs) will be 
presented by treatment group.  Estimates of the mean difference between each active treatment 
group and placebo group, the standard error of the difference, and 95% CI of the difference will 
be presented.  Baseline is defined as the mean of all available evaluations before treatment.

All efficacy analysis at EOS will be conducted using the ITT population (only including 
fibrosis stage 2 and 3 subjects).  The hypothesis testing of primary and (key) secondary 
endpoints will be conducted in with control of Type 1 error (OCA 25 mg, then 10 mg).  
Adjustments for multiplicity are specified in Section 16.7 and additional details on the testing 
at EOS will be provided in the SAP. 
The primary efficacy endpoint at the EOS will be the time to first occurrence of one of the 
following post-randomization:  
•
Death (all-cause)
•
MELD score ≥15
•
Liver transplant
•
Hospitalization (as defined by a stay of 24 hours or greater) for onset of:
−
Variceal bleed
−
Hepatic encephalopathy (as defined by a West Haven score of ≥2)
−
Spontaneous bacterial peritonitis (confirmed by diagnostic paracentesis)
•
Ascites secondary to cirrhosis and requiring medical intervention (eg, diuretics or
paracentesis)
•
Progression to cirrhosis

Confidential and Proprietary 
The primary efficacy analysis for clinical outcomes at EOS will test the following hypothesis: 
•
H01:  The time to first occurrence of any of the adjudicated events for all-cause
mortality and liver-related clinical outcomes are equal between placebo and OCA.
•
H11:  The time to first occurrence of any of the adjudicated events for all-cause
mortality and liver-related clinical outcomes are different between placebo and OCA.
Only adjudicated events (including progression to cirrhosis) will be included in analyses.  
Placebo and each OCA dose will be compared separately using a log rank test stratified by the 
randomization stratification factor.  Kaplan-Meier (KM) estimates of the distribution of the time-
to-event will be tabulated and graphed by treatment group.  Subjects without any documentation 
of events will be censored at the date of last contact.  The tabulation will include the KM 
estimate of the medians and corresponding 95% 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. 
16.4.2.

Confidential and Proprietary 
Descriptive statistics of the laboratory values will be summarized by treatment group and visit. 
The results, change from baseline, and percentage change from baseline values as well as 
estimates of least-square (LS) means, standard errors, and 95% Cis, will be presented by 
treatment group.  Estimates of the mean difference between each active treatment group and 
placebo group, the standard error of the difference, and 95% CI of the difference will be 
presented.  Baseline is defined as the mean of all available evaluations before treatment. 
Each active OCA treatment group will be compared to placebo using the log rank test stratified 
by the randomization stratification factor.  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% 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. 
16.5. 
Interim Analyses Post Month 18 Interim Analysis 
There will be 2 planned interim analyses to be conducted using group sequential approach in 
accordance to the SAP and DMC Charter at the accumulation of 50% and 80% of the total 
planned 291 adjudicated clinical outcome events.  The primary efficacy endpoint for these 
planned interim analyses will be the clinical outcomes composite endpoint.  
If either of these 2 Interim Analysis are significant, then all analyses described in Section 16.4 
will be carried out. 
16.6. 
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. 

Protocol 747-303 
Version 11.0: 04May2021

Confidential and Proprietary 
16.6.1. 
Time to Event Endpoints 
For the time-to-event analyses, including the primary clinical outcomes composite endpoint, only 
adjudicated events (including biopsy confirmed progression to cirrhosis) will be included.  
Subjects who do not experience an adjudicated event will be censored at the time of their last 
contact.  Sensitivity analyses will be described in the SAP. 
16.6.2. 
Quantitative Endpoints 
For other efficacy endpoints utilizing an ANCOVA model, mixed-effect repeated measures 
model or the Wilcoxon Rank Sum Test, observed cases will serve as the primary analysis.   
16.6.3. 
Responder Endpoints 
For the analyses of the primary and key secondary histological efficacy endpoints, in which 
subjects are classified as either a responder or a non-responder (binary outcome), any subject 
who does not provide any assessment at the specified timepoint and after baseline 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.  Subjects who early terminate before Month 18, biopsy results at the time of early 
termination, if available, will be included in Month 18 histological endpoints analyses. 
A completer analysis will also be conducted, 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. 
Additional sensitivity analysis will be described in the SAP. 
16.7. 
Multiple Comparisons/Multiplicity 
The 2-sided alpha allocated to all testing in this single study will be 0.05.  The histological 
endpoints will be tested at the Month 18 Interim Analysis with alpha level of 0.02.  The 
primary clinical outcomes endpoint will be tested with a minimum alpha level of 0.03, which 
may be augmented by recycled alpha from the Month 18 Interim Analysis.  Further details 
are provided in the SAP. 
16.7.1. 
Multiplicity Adjustment for the Month 18 Interim Analysis 
For the Month 18 Interim Analysis, testing methods to control overall Type 1 error will be 
implemented.  The sequential testing order will be:  primary endpoints in 25 mg versus 
placebo, followed by primary endpoints in 10 mg versus placebo; details will be provided in 
the SAP. 
16.7.2. 
Multiplicity Adjustment for Interim (Post Month 18 Interim Analysis) and EOS 
Analyses 
For the interim and EOS analyses of the primary and (key) secondary endpoints, OCA will 
be compared to placebo.  O’Brien-Fleming type alpha-spending function will be used to 
control overall alpha level allocated for clinical outcomes for DMC analysis at 50% and 80% 
information fraction and at EOS. 

Protocol 747-303 
Version 11.0: 04May2021

Confidential and Proprietary 
The SAP will specify the methods and alpha levels for the interim analyses and EOS final 
analysis.  The DMC will review the interim criterion for efficacy in conjunction with detailed 
safety data and other relevant information to determine whether to continue the study.  
16.8. 
Examination of Subgroups 
Both at the interim and final analyses, the primary and key secondary efficacy endpoints will be 
analyzed for subject subgroups (eg, age, sex, and race) using the ITT population.  Subgroups will 
be assessed at Baseline and only if there are a sufficient number of subjects in each group 
(eg, >5 subjects per group). 
Key subgroups of interest are fibrosis stage and diabetes status.  Additional parameters for 
subgroup analyses include, but are not limited to:  age, sex, race, BMI, NAS, ballooning, FRS, 
statin or antihypertensive medication use, ALT, AST, GGT, and geographic region.  Further 
details regarding subgroups analyses will be specified in the SAP. 
16.9. 
Safety Analysis 
Safety data, including AEs and clinical laboratory observations, will be summarized by treatment 
group using the Safety Population.  The evaluation of safety data will be conducted at both the 
interim and final analyses.  
16.9.1. 
Adverse Events 
AEs will be coded using the Medical Dictionary of 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. 
16.9.2. 
Hepatic and Renal Safety Adjudication 
Potential events of hepatic injury and AKI will be adjudicated during the study (Section 16.11).  
The adjudication of the events of hepatic injury will be separate from the adjudication of events 
for assessment of the primary outcomes endpoint 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. 
16.9.3. 
Cardiovascular Event Adjudication 
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 treated 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 
(CAC) Charter for adjudication.  The adjudication of these events will be handled separately 
from the adjudication of events for assessment of the primary endpoint in this study (See 

Protocol 747-303 
Version 11.0: 04May2021
Page 132
Confidential and Proprietary 
Section 16.11).  Undetermined cause of death will be classified as a cardiovascular death by the 
CAC. 
There will be no formal hypothesis testing of MACE at the Month 18 Interim Analysis.  The 
EOS assessment of MACE will include all MACE events occurred from the start of the study. 
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.  
The time-to-event endpoints include: 
•
Time from randomization to the first confirmed occurrence of cardiovascular death,
nonfatal myocardial infarction, nonfatal stroke, or nonfatal unstable angina requiring
hospitalization
•
Time from randomization to the confirmed occurrence of cardiovascular death
(including fatal myocardial infarction, fatal stroke)
•
Time from randomization to the first confirmed occurrence of myocardial infarction
(nonfatal or fatal)
•
Time from randomization to the first confirmed occurrence of stroke (nonfatal or
fatal)

procedure
•
Time from randomization to the first occurrence of hospitalization for congestive
heart failure
•
Time from randomization to the first occurrence of transient ischemic attack
•
Time from randomization to the first occurrence of arrhythmia
Placebo and the 2 dose levels of OCA will be compared separately using a log rank test stratified 
by the randomization stratification factor.  KM estimates of the distribution of the time-to-event 
will be tabulated and graphed by treatment group.  Subjects without any documentation of events 
will be censored at the date of last contact.  The tabulation will include the KM estimate of the 
medians and corresponding 95% 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.

Cardiovascular Risk Assessments 
Cardiovascular risk scores will be calculated for assessments including: 
•
FRS
•
Reynolds score
•
SCORE
•
10-year ASCVD Risk based on Pooled Cohorts Equation
Each score is derived from a subject’s age, sex, smoking status, total cholesterol and HDL levels, 
systolic blood pressure, and other factors including family history, BMI, ethnicity, and 
medications. 
These cardiovascular assessments will be summarized by treatment group using descriptive 
statistics at Baseline and at each on-study evaluation.  The change and percentage change from 
Baseline will also be summarized.  Baseline is defined as the last assessment before treatment.  
Further analysis details will be specified in the SAP. 
16.9.5. 
Clinical Laboratory Evaluations 
Laboratory parameters will be summarized by treatment group using descriptive statistics at 
Baseline and at each on-study evaluation.  The change from Baseline will also be summarized. 
Baseline is defined as the mean of all available evaluations before treatment.   
In addition, shift tables from Baseline based on normal ranges and CTCAE grade to each 
scheduled post-Baseline visit will be provided for hematology, coagulation, and serum chemistry 
by treatment group to assess changes in laboratory values from Baseline to each on-study 
evaluation.   
16.9.6. 
Lipoprotein Evaluations 
Lipoprotein samples, separate from the serum chemistry samples, collected for a subset of 
subjects up to Version 7 of the protocol, will be assayed in addition to serum lipid analyses 
performed as part of the serum chemistry panel.  The lipoprotein analyte values, change from 
baseline, and percentage change from baseline will be summarized by treatment group for the 
lipoprotein analytes.  Baseline is defined as the last fasting assessment before treatment.  This 
analysis will use only samples that have a confirmed fasting of approximately 8 hours or more 
before their visit.  Further analyses of lipoprotein analytes will be specified in the SAP. 
Subgroup analyses will also be presented by use of statin medication. 
16.9.7.

The ECG data analysis will be conducted based on methodology recommended in the ICH E14 
guideline, The Clinical Evaluation of QT/QTc Interval Prolongation and Proarrhythmic Potential 
for Nonantiarrhythmic Drugs.   
Baseline is defined as the mean of all available evaluations before treatment.  Descriptive 
statistics of ECG parameters (time between 2 consecutive R waves [RR], PR, QRS, QT, and QT 
interval corrected by the Fridericia’s formula [QTcF]) at baseline and at each post-baseline 
timepoint will be summarized by treatment group; absolute changes from baseline will also be 
summarized.   
A categorical summary of abnormal QTcF values will be presented by treatment group.  The 
number of subjects with values of >450 msec, >480 msec, and >500 msec will be presented, and 
the number of subjects with change from baseline values of >30 msec and >60 msec will also be 
presented.   
Overall interpretation results for ECGs and the investigator interpretation results are collected as 
normal, abnormal not clinically significant (NCS), and abnormal clinically significant (CS).  
Subjects whose interpretation shifts from normal to abnormal (CS or NCS) will be listed 
separately including description of the abnormality and any associated comments. 
16.10. 
Data Monitoring Committee 
An independent DMC that includes hepatologists, pharmaceutical physicians, 
epidemiology/cardiology 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 Food and Drug Administration (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 meet approximately quarterly at scheduled meetings and ad hoc meetings will be 
convened, as appropriate, to review safety and efficacy data as well as the adjudication 
assessments from the 4 adjudication committees listed in Section 16.11.  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 
is locked. 
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, 

Protocol 747-303 
Version 11.0: 04May2021

Confidential and Proprietary 
specific summary data focused on hepatic and renal safety are reviewed by the DMC, including 
an aggregate unblinded summary of adjudicated cases of potential 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. 
Data flow, access, process and disclosure will be described in a DAP.  The DAP will cover the 
process by which an independent statistical group will conduct analyses and provide to the 
DMC, including the Month 18 Interim Analyses to support regulatory filing for conditional 
marketing approval. 
16.11. 
Adjudication Committees 
All potential liver-related clinical outcomes and potential events of hepatic injury, AKI, MACE, 
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: 
•
CAC:  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 including clinical events and histological findings of potential
disease progression to cirrhosis
•
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.   
Specific details of the events that will be adjudicated by the CAC, Hepatic Outcomes Committee, 
HSAC, and 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 all study sites outside of a protocol 
amendment. 
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.  Any 
candidate found to have a conflict or whose name is listed on the FDA debarment list is not 

Protocol 747-303 
Version 11.0: 04May2021
Page 136
Confidential and Proprietary 
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.   
Histological progression to cirrhosis will be determined by central reading of liver biopsies. A 
biopsy evaluation form signed by one of the study-specific central pathologists will be necessary 
to confirm histological progression to cirrhosis.  Clinical events and histological findings of 
potential disease progression to cirrhosis will be adjudicated by the Hepatic Outcomes 
Committee.  The end of study primary efficacy endpoints of clinical composite outcome events 
are described in Section 16.4.1.  
17.
DIRECT ACCESS TO SOURCE DATA/DOCUMENTS
17.1. 
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 CRF.  The CRF 
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. 
17.2. 
Audits and Inspections 
The Investigator should understand that it may be necessary for the Sponsor, the IRB/IEC and/or 
a regulatory agency 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.   
17.3. 
Documentation Associated with Interim Data 
To ensure continued unbiased conduct during the study and unbiased analysis at the end of the 
study, a select group of unblinded personnel will be identified and charged with producing the 
associated unblinded documents to support regulatory submissions for conditional marketing 
approval.  All other personnel, including those charged with completing the study, will remain 
blinded to individual subject treatment assignments and unblinded aggregated data as described 
in the DAP.   
18.
QUALITY CONTROL AND QUALITY ASSURANCE
Logic and consistency checks will be performed on all data entered into the CRF or ultimately 
transferred into the database to ensure accuracy and completeness.   
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 17.2 for more details regarding the audit 
process. 
19.
ETHICS
19.1. 
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 the Sponsor 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 ethics committee for review. 
The Investigator is responsible for informing the IRB/IEC of any revisions to the protocol in 
accordance with local requirements.  A favorable opinion on revisions will be obtained before 
implementation, unless the revisions are 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 or IEC upon receipt of revisions 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.  
The Sponsor will provide this information to the Investigator.

written information about the nature, purpose, possible risk 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 ICF(s) must be obtained before conducting any study procedures. 
The Investigator(s) must maintain the original, signed ICF(s).  A copy of the ICF(s) must be 
given to the subject. 
19.4. 
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 reports and communications relating to subjects in this 
study that are disclosed to an authorized third party will identify subjects only by protocol and 
assigned number and will be shared in a secure manner.  All data shall be secured against 
unauthorized access. 
The Investigator will maintain a list of subject’s names and identifying information (eg, subject’s 
hospital number, unique subject number).  This list will not be collected by the Sponsor. 
The written information sheet 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 their disclosure to unauthorized third parties.  The pertinent sections of the data 
protection laws in which the country is being conducted will be complied with in full.

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. 
20.2. 
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 revise 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 revision 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. 
20.3. 
Regulatory Documentation 
The following regulatory documentation must be completed or provided, and maintained: 
•
Approved ICF (all versions)
•
IRB/IEC approvals (of protocol/subsequent revisions, subject questionnaires, etc)
•
Form FDA 1572
•
Current medical license
•

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. 
21.
PUBLICATION POLICY
The Sponsor intends to publish the results of all of the clinical studies that it Sponsors consistent 
with the Declaration of Helsinki (64th WMA General Assembly, Fortaleza, Brazil, 
October 2013).  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 Study Registries (eg, clinicaltrials.gov):  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 (when available)
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.

Protocol 747-303 
Version 11.0: 04May2021
Page 141
Confidential and Proprietary 
•
Data Management:  The Sponsor will establish data management 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 before 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 before 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:  The Sponsor, 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
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 before 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 subsequent revisions, 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.

APPENDIX A. MANAGEMENT OF CHANGES IN CHOLESTEROL 
In previous studies evaluating obeticholic acid (OCA) for nonalcoholic fatty liver disease 
(NAFLD) and nonalcoholic steatohepatitis (NASH), changes in lipid profile were observed in 
response to OCA therapy.  As described in the Investigator’s Brochure, data from these studies 
suggest that any OCA-induced increase in low-density lipoprotein (LDL) cholesterol can be 
managed by statins.  While there are no long term data with OCA in NASH to assess any 
long-term increase in cardiovascular risks, given the increased cardiovascular mortality in NASH 
patients in general, it is important to monitor for changes in cholesterol levels, and manage LDL 
levels in the context of other risk factors.  
Statins are sometimes reluctantly used by healthcare professionals in patients with NAFLD or 
NASH, which may in part be due to the contraindication in statin package inserts for use in 
patients with active liver disease.  There is growing evidence of the safety of statins in patients 
with elevated baseline liver enzymes, including in subjects with compensated NAFLD/NASH.  
During the conduct of Study 747-303, routine study visits provide an opportunity to detect any 
adverse effects that may arise due to blinded or open-label study drug or concomitant medication 
use such as statins through various assessments of the liver.  Liver enzyme elevations are usually 
reversible with continued use or after discontinuing treatment without evidence of long-term 
injury. 
The purpose of this guidance document is to provide participating Investigators a uniform 
approach for monitoring LDL concentrations and considering treatment of LDL cholesterol 
increases during the study.  The Investigator may consider alternate cholesterol management 
strategies on a case-by-case basis.  This guidance summarizes recommendations for the 
management of LDL cholesterol based on the ACC/AHA 2019 Guideline on the Primary 
Prevention of Cardiovascular Disease (Arnett 2019) and the European Guidelines for the 
Management of Dyslipidaemias: Lipid Modification to Reduce Cardiovascular Risk 
(Mach 2020).   
Investigators should closely monitor subjects’ LDL concentrations and evaluate each subject 
with respect to:  
•
Magnitude of LDL increase (ie, absolute LDL value in the context of individual
cardiovascular risk profile)
•
Cardiovascular risk factors
•
Risk-benefit assessment of statin or other appropriate dyslipidemia therapy
•
Any other factors that are relevant to dyslipidemia management
Recommended LDL Management Algorithm (Figure A1): 
•
Investigators and/or study staff will be alerted by the central laboratory when a ≥15%
increase from baseline is detected in a subject’s LDL concentration as part of the
standard lab panel conducted at every study visit.
−
If an LDL value is elevated and the subject reports having eaten within 8 hours
before the blood draw, the Investigator may repeat the assessment under fasting
conditions to better assess the magnitude of the increase.

Protocol 747-303 
Version 11.0: 04May2021
Page 147
Confidential and Proprietary 
•
If the LDL cholesterol increase of ≥15% relative to study baseline is confirmed,
Investigators should also assess any other cardiovascular disease risk factors that may
be present.  A subject may be considered at high risk for cardiovascular disease if any
of the following factors are present:
−
History of atherosclerotic cardiovascular disease (eg, prior myocardial infarction,
angina) or cerebrovascular disease
−
High LDL and/or low high-density lipoprotein values
−
Age >50
−
Diabetes mellitus
−
Hypertension
−
Tobacco smoker
−
Male gender
•
If the Investigator determines that intervention is warranted after a risk-benefit
analysis for statin versus non-statin dyslipidemia therapy, the Investigator may:
−
Initiate statins at an appropriate dose (high-, moderate-, or low-intensity statin
depending on the subject’s cardiovascular risk profile) in subjects who are not
currently taking a statin
−
Up-titrate statin dose in subjects who are already taking a statin at less than
maximum (or maximum tolerated) dose or switch to a more potent statin in
subjects taking maximum dose of a low or moderate intensity statin
−
Initiate or up-titrate non-statin dyslipidemia therapy in subjects for whom statin
use is not preferred or are already on a maximum (or maximum tolerated) statin
therapy (eg, ezetimibe, fibrates, PCSK9 inhibitors, and bile acid sequestrants [see
protocol for instructions regarding dosing of investigational product and bile acid
sequestrants])
•
If any dyslipidemia therapy is initiated or up-titrated:
−
The new concomitant medication or change in dose must be documented on the
case report form (CRF);
−
Dyslipidemia therapy initiation or dose adjustments may be considered
appropriate to achieve LDL concentrations at or below baseline
−
If treatment with statins is initiated, women of childbearing potential must be
informed that statin use is contraindicated during pregnancy.  Methods of
contraception should be reviewed and modified if necessary to ensure highly
effective methods with failure rates <1% per year, such as implants, injectables,
combined oral contraceptives, some intrauterine devices, sexual abstinence, or
history of vasectomy of partner are used.

•
If the Investigator determines that intervention is not necessary, based on LDL
evaluation and assessment of other risk factors, this decision and the reason for the
decision must be documented on the CRF.
This guidance may be updated over the course of the study as cardiovascular disease prevention 
guidelines evolve over time.  New lipid findings as a result of ongoing evaluations will be 
included in the Investigator’s Brochure during periodic updates.

Cardiovascular (CV) Death:
Death due to Acute :MI 
Sudden Cardiac Deatl1 
Confidential and Proprieta1y 
Death due to Acute MI refers to a death by any CV mechanism (eg, all'hytlunia, sudden death, HF, stroke, 
pulmomuy embolus, peripheral arterial disease) ::;30 days• after a MI related to the immediate consequences of 
the Ml, such as progressive HF or recalcitrant a1Thythmia. There may be assessable mechanisms of CV death 
during this time period but for simplicity, if the CV death occms ::;30 days of the Ml, it will be considered a 
death due to MI. 
Acute MI should be verified to the extent possible by the diagnostic criteria outlined for acute MI (Clinical Data 
Interchange Standards Consortium [CDISC], Chapter 4) or by autopsy findiugs showiug recent :MI or recent 
coronary thrombosis. 
Death resulting from a procedure to treat a MI (percutaneous coronruy iutervention (PCI), coromuy aite1y bypass 
graft surge1y [CABG]), or to treat a complication resultiug from Ml, should also be considered death due to acute 
MI. 
Death resultiug from an elective coronaty procedure to treat myocardial ischetnia (ie, chronic stable angiua) or 
death due to a MI that occurs as a direct consequence of a CV investigation/procedure/operation should be 
considered as a death due to a CV procedure. 
Sudden Cai·diac Death refers to a death that occurs unexpectedly, not following an acute Ml, and iucludes the 
following deatlis: 
a.
Death witnessed and occurriug without new or worsening symptoms
b.
Death witnessed within 60 minutes of the onset of new or worsening cardiac symptoms, unless tlie
symptoms suggest acute MI
c.
Death witnessed and attributed to an identified a1Thythmia ( eg, captured on at1 electrocai·diographic
(ECG) recordiug, witnessed on a monitor, or unwitnessed but found on implantable cardioverter­
defibrillator review)
d.
Death after unsuccessful resuscitation from cardiac arrest ( eg, implantable cardiove1ter defibrillator (ICD)
unresponsive sudden cai·diac death, pulseless electrical activity a!l'est)
e.
Death after successful resuscitation from cardiac an·est at1d without identification of a specific cai·diac or
non-cru·diac etiology
f.
Unwitnessed death iu a. subject seen alive and clinically stable ::;24 hours prior to being found dead
without any evidence supporting a specific non-CV cause of death (infonnation regardiug the subject's
clinical status preceding deatl1 should be provided, if available).
Unless additional infomiation suggests an alternate specific cause of deatli (eg, death due to Other CV Causes), if 
a subject is seen alive ::;24 hours of being found dead, sudden cardiac deatl1 (criterion f above) should be 
recorded. For subjects who were not obsenred alive within 24 hours of death, undetermiued cause of deatli 
should be recorded (eg, a subject found dead iu bed, but who had not been seen by family for several days).

Version 11.0: 04May2021 
Page235 
Death due to HF refers to a death in association with clinically worsening symptoms and/or signs of HF 
regardless of HF etiology (CDISC, Chapter 7). Deaths due to HF can have various etiologies, including single or 
recunent Mls, ischemic or 11011-ischemic cardiomyopathy, hypertension, or valvular disease. 
Death due to Stroke refers to death after a stroke (hemorrhagic, ische1n.ic, or undete1mined) that is either a direct 
consequence of the stroke or a complication of the stroke. Acute stroke should be verified to the extent possible 
by the diagnostic criteria outlined for stroke (CDISC, Chapter 6). 
Death due to CV Procedures refers to death caused by the immediate complications of a cardiac procedure. 
Death due to CV Hemonhage refers to death related to hemonhage such as a non-stroke intracran.ial hemonhage 
(CDISC, Chapter 6), non-procedural or non-traumatic vascular mpture (eg, aortic aneurysm), or hemorrhage 
causing cardiac tamponade. 
Death due to Other CV Causes refers to a CV death not included in the above categories but with a specific, 
known cause (eg, pulmonary embolism or peripheral arterial disease). 
Non-CV death is defined as any death with a specific cause that is not thought to be CV in nature, as listed in 
CDISC Chapter 1, or as listed for CV Death.

Version 11.0: 04May2021 
Page236 
Undetermined cause of death refers to a death not attributable to one of the above categories of CV death or is 
due to a non-CV cause. Inability to classify the cause of death may be due to lack of infonnation ( eg, the only 
available information is "subject died") or there is insufficient supporting infonnation or detail to assign the cause 
of death. In general, most deaths should be classifiable as CV or non-CV, and the use of this category of death 
therefore, should be discouraged and should apply to few subjects in well-nm clinical trials. 
a)
Clinical Presentation
The clinical presentation should be consistent with diagnosis of myocardial ischemia and infarction. Other
findings that might suppmt the diagnosis of MI should be taken into account because a number of conditions are
associated with elevations in cardiac biomarkers (eg, trauma, surge1y, pacing, ablation, HF. hypertrophic
cardiomyopathy, pulmonary embolism, severe pulmonary hype1tension stroke or subarachnoid hemoIThage
infiltrative and inflammat01y disorders of cardiac muscle drug toxicity, bums, critical illness, extreme exertion,
and chronic kidney disease).
Supporting infmmation can also be considered from myocardial imaging and coronary imaging. The totality of
the data may help differentiate acute MI from the bac.kground disease process.
b)
Biomarker Elevations
For cardiac biomarkers, laboratories should repmt an upper reference limit (URL). If the ninety-ninth percentile
of the URL from the respective laboratmy perfom1ing the assay is not available, then the URL for myocardial
necrosis from the laboratmy 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 paiticular laboratory should be used as the URL.
Laboratories cai1 also report both the ninety-ninth percentile of the upper reference limit and the MI decision

Version 11.0: 04May2021

Event 
Definitions 
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
−
Q-wave ≥0.03 seconds and ≥0.1 mV deep or QS complex in leads I, II, aVL

Pathological Q-waves, as defined above
−
R-wave ≥0.04 seconds in V1-V2 and R/S ≥1 with a concordant positive T-wave in the absence of a

available).
AND 
3.
At least one of the following:

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

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 symptoms at all 
1 
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 able to look after own affairs

Moderate disability; requiring some help, but able to walk without assistance 
4 
Moderately severe disability; unable to walk without assistance and unable to attend to 
own bodily needs without assistance

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 (CFR), or fractional flow reserve (FFR), insertion of a 
guide wire will NOT be considered PCI.

Definitions 
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

Event 
Definitions 
The target vessel(s) and the type of revascularization procedure (eg, surgical bypass, thrombectomy, 
endarterectomy, percutaneous transluminal angioplasty, stent placement, thromboembolectomy, and 
thrombolysis) should be specified and recorded. For the sake of simplicity, this definition applies to the 
extracranial carotid artery and other non-cardiac arteries and veins and excludes the intracranial vessels and 
lymphatics. 
Procedural Success: 
In the case of percutaneous intervention for obstructive lesions, procedural success is defined as the achievement 
of a satisfactory final residual diameter stenosis by angiography at the end of the procedure (and without flow 
limiting dissection or hemodynamically significant translesional pressure gradient).  The specific parameter for 
final percent residual stenosis is typically between <30% and <50%; selection of the appropriate percentage may 
vary depending upon the specific intervention applied, the vascular territory, and anticipated or desired 
therapeutic response.  Procedural success also implies absence of in-hospital major adverse events (eg, death, 
stroke, myocardial infarction, acute onset of limb ischemia, need for urgent/emergent vascular surgery, and other 
procedure-specific major adverse events).  The balloon inflation, stent placement, or other therapeutic 
intervention may be preceded by use of adjunctive devices (eg, percutaneous mechanical thrombectomy, 
directional or rotational atherectomy, laser, and chronic total occlusion crossing device), as predefined in the 
protocol. 
Procedural Status: Non-Elective and 
Elective: 
a.
Non-Elective:  Non-elective procedures include emergent and urgent procedures.  A non elective
procedure is a procedure that is performed without delay, because there is clinical consensus that the
procedure should occur imminently. Non-elective procedures imply a degree of instability of the subject,
urgency of the medical condition, or instability of the threatening lesion.
−
Emergent:  A procedure that is performed immediately because of the acute nature of the medical
condition (eg, acute limb ischemia, acute aortic dissection), and the increased morbidity or mortality
associated with a temporal delay in treatment.
−
Urgent:  An urgent procedure is one that is not an emergency but is required to be performed on a
timely basis (≤24 hrs) (eg, a subject who has been stabilized following initial treatment of acute limb
ischemia, and there is clinical consensus that a definitive procedure should occur within the next
24 hours).
b.
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).

Event 
Definitions 
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 tibial-crural. 
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. 
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 Lesion 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 any segment of the target vessel. 
In the assessment of TVR, 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. 
Clinically-Driven Target Lesion 
Revascularization: 
Clinically-driven target lesion revascularization is defined as target lesion revascularization performed due to 
target lesion diameter stenosis >50% AND either evidence of clinical or functional ischemia 
(eg, recurrent/progressive intermittent claudication, critical limb ischemia) OR recurrence of the clinical 
syndrome for which the initial procedure was performed.  Clinically-driven target lesion revascularization occurs 
in the absence of protocol-directed surveillance ultrasound or angiography. 
Vessel Patency: 
Vessel patency at a given time point will be determined by the absence of clinically-driven target lesion 
revascularization and/or absence of recurrent target lesion diameter stenosis >50% by imaging (eg, invasive 
angiography or most commonly, duplex ultrasonography). If patency data are incorporated within the primary 
endpoint of a clinical trial, the angiographic images or duplex ultrasonographic images should be assessed by 
appropriate core laboratories and made available to the AC for review upon request.

APPENDIX F. SUMMARY OF CHANGES: PROTOCOL 747-303 VERSION 11.0 
(DATED 04 MAY 2021) 
Protocol 747-303 was revised to include the following information: 
1) Update to the end-of-study primary objective for progression of cirrhosis to include all clinical evidence beyond only
histological changes
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 due to
suspected hepatic injury and progression to cirrhosis, within 7 days of experiencing a serious adverse event, and at the time of

OCA-related changes in serum lipids (decrease 
in high-density lipoprotein cholesterol [HDLc) 
and increase in LDLc) have been observed in 
healthy volunteers, in subjects with PBC and 
NASH, and in subjects with other underlying 
conditions. However, the pattern and 
magnih1de, as well as the clinical significance of 
these changes, are not well understood and 
dearly depend on a subject's underlying 
condition and other comorbidities. Although 
increases in LDLc have generally been 
considered to be associated with increased 
cardiovascular risk, it is not possible to draw 
conclusions regarding the cardiovascular effect 
of OCA-related changes in lipid proftle given the 
concurrent positive effects of OCA on other 
metabolic factors such as a decrease in hs-CRP 
(in PBC studies), and relative improvement of 
triglyceride and very low-density lipoprotein 
(VLDL) cholesterol levels. In order to better 
assess cardiovascular risk, longer treatment 
periods and larger numbers of subjects are

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, decreased 
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 J'ecorded as well as all 
centrnl lab data (scheduled or unscheduled visits) 
to adequately capture events. Repeat laboratory 
assessments should include albumin, serum 
chemistry (creatinine, BUN, elech·olytes),
urinalysis with microscopic examination, and 
assessment of estimated glomerular f'Iltration 
rate (eGFR). All local laboratory 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 impail'ment 
and the actions to be taken with investigational

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 . 
... 
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 laborato111 reference ranges and the 
results should be made available to the 
Investigator. All local laboratory data, including 
reference ranges, should be entered into the 
eC
RF 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 intercun:ent illness 
should be conducted. If no alternative 
cause of serum creatinine elevation can

adherence to ncommended dietary measures, 
adequate fluid intake, and other measures 
presrribed should be employed to prevent 
recurrent episodes of kidney stones (Pearle 
2014). Subjects should be asked if they have 
experienced symptoms of nephrolithiasis 
(evidence of hematuria, flank or lower 
abdominal pain, nausea, vomiting, fever, or 
chills). 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.

9.3.1. 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 de1ivatives, colestipol, 
colesevelam, or other sequestrants) or aluminum 
hydroxide- or smectite-containing antacids should 
be instrncted to stagger their dosing of 
investigational product in temporal relation.ship to 
these agents, ensming 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 ti·eat pruritus ԘGrade 
2 in seve1ity refer to Section 15.1.5.1. 
Due to the potential of BAS to affect the 
disposition of OCA, long-term llse of BAS should 
be avoided where possible while taking 
investigational prnduct. In subjects taking long-
term BAS for other medical conditions ( eg, 
hypercholesteremia), other therapies to replace 
the BAS should be considered. 
9.3.2. Other Concomitant Medications

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 monito1· and manage lipid levels in all 
participants as indicated via appropriate 
medicinal inte1--ventions (eg, statins). Recent 
guidelines stress the importance of evaluating 
atherosclerotic cardiovasculu disease (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 
low-density lipoproteins, are part of a 
comprehensive cardiovascular risk reduction

strntegy. Results from meta-analyses have 
con.finned t.he dose-dependent reduction in 
ASCVD with LDLc-lowering agents; the greater 
the absolute LDLc reduction, the greate1· the CV

management of lipids, such as the 2019 ESC/EAS 
Guidelines (Mach 2020), suggest that LDLc 
targets should be individualized based on 
available treahnents and each subject's overall 
ASCVD risk proflle. The tai·geted approach to 
lipid management is aimed at reducing 
atherosclerotic risk by substantially lowering 
LDLc to levels that have been achieved in recent

interventions based on current guidelines to 
mitigate potential elevations of serum glucose

vision, fatigue and headaches should also be

Subjects who experience treatment-emergent 
hyperglycemia should be closely monitored and 
treatment should be based on cunent 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 seve1ity 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 
undel'lying risk factors including underlying 
cardiovascular and renal disease. According to 
these guidelines, glycemic treatment ta1·gets 
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 measming 
HbAlc 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 the patient-cente1·ed 
care.

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 an unable 
to return to study sites for evaluations and/or to 
receive continued supply of investigational 
product. Enforcement of many 1·estl'ictions by 
local autho1ities have also affected the site 
monitor's ability to pe1·fonn on-site monitoring 
duting 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 nreive 
investigational product until in-person site visits 
can resume. To ensure the continued safety 
monitoring of the participating subject and to

achieving the objectives of the study due to the 
restrictions from the COVID-19 pandemic, the 
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 c.ontinued 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
electrnnic 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 a
qualified healthcare professional who is
currently authorized 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 laboratOI)' tests are to be sent to the
Investigator and entered in to the eCRF within
2 days of receiving 1·esults. Note: Investigational
product can only be dispensed if central or local
laboratory values are available.

not able to attend study site visits. Dinct

Home Visits: If laboratory tests cannot be
obtained from local laboratories, home nursing
support (where available and permitted) is an
accepted option that may be employed to
supplement telemedkine 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 requiJ·ed subject
questionnaires).

Monitoring: Cancelling or postponing of on-
site monitoring visits and extension of the period
between monito1ing 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
