Objectives: 
Primary: 
•
To assess the 12-week efficacy of bempedoic acid (ETC-1002) 180 mg/day versus placebo in
decreasing low-density lipoprotein cholesterol (LDL-C) in high cardiovascular (CV) risk patients
with hyperlipidemia (with underlying heterozygous familial hypercholesterolemia [HeFH] and/or
atherosclerotic cardiovascular diseases [ASCVD]) who are not adequately controlled with their
maximally tolerated lipid-modifying therapy.
Secondary: 
•
To evaluate the effect of 24-week treatment with bempedoic acid 180 mg/day versus placebo on
LDL-C.
•
To evaluate the effect of bempedoic acid 180 mg/day versus placebo on non-high-density
lipoprotein cholesterol (non-HDL-C), total cholesterol (TC), high-sensitivity C-reactive protein
(hs-CRP), and apolipoprotein B (apoB) after 12 weeks of treatment.
Tertiary: 
•

Approximately 750 eligible patients will be randomized 2:1 on Day 1 (Visit T1) to receive either 
bempedoic acid 180 mg (n = 500), or placebo (n = 250) once daily for 52 weeks.  Randomized patients 
will return for clinic visits at Week 4 (Visit T2), Week 12 (Visit T4), Week 24 (Visit T5), and Week 52 
(T7).  A phone visit will occur at Week 8 (Visit T3) and Week 36 (T6).  Patients who withdraw from 
investigational medicinal product (IMP) treatment will be asked to continue to be followed for safety 
using the protocol-specified visit schedule and procedures.  For details of study assessments, see the 
Schedule of Events in Appendix 1. 
An independent expert Data Monitoring Committee (DMC) will formally review accumulating unblinded 
safety and efficacy data from this and other ongoing studies of bempedoic acid.  A blinded independent 
expert Clinical Events Committee (CEC) will adjudicate designated clinical endpoints, including all 
major adverse cardiac events (MACE) and non-MACE endpoints defined as:  CV death (MACE), non-
CV death (non-MACE), nonfatal myocardial infarction [MI] (MACE), nonfatal stroke (MACE), 
hospitalization for unstable angina (MACE), coronary revascularization (MACE), non-coronary arterial 
revascularization (non-MACE), and hospitalization for heart failure (non-MACE) using standardized 
definitions. Any clinical endpoints that meet serious adverse event (SAE) criteria will be reported as 
SAEs.

regimens other than daily dosing, including no to very low doses, but reasons for not using high-
intensity statin dosing must be documented.  
A patient’s maximally tolerated lipid-modifying therapy will be determined by the investigator using 
their medical judgment and available sources, including the patient’s self-reported history of lipid-
modifying therapy.  
Note:  Patients can be on any available lipid-modifying therapy with the exception of the exclusions 
listed below as long as they have been stable for 4 weeks prior to Screening Visit S1 and are taken at 
a consistent time each day.  In the case of PCSK9 inhibitor use, the patient must have received 
3 stable doses.  It is important that lipid values are measured at PCSK9i trough levels.  Therefore, 
study visits should be scheduled in accordance with the patient’s PCSK9i injection regimen so that 
measurement of lipid values for all visits occurs before the PCSK9i injection but not greater than 
48 hours before the next scheduled PCSK9i injection.  Patients who have discontinued investigational 
or commercial PCSK9 inhibitor must have had their last dose at least 4 months prior to Screening 
Visit S1. 
Exclusion Criteria: 
1. Total fasting (minimum of 10 hours) TG ≥500 mg/dL (5.6 mmol/L) at Week -5 (Visit S1) 
Note: TG may be repeated 1 time between Visits S1 and S2.  For those patients who have a repeat 
TG, the repeat value will be used to determine eligibility. 
2. Renal dysfunction or nephritic syndrome or a history of nephritis, including estimated glomerular 
filtration rate (eGFR) (using central laboratory determined Modification of Diet in Renal Disease 
[MDRD] formula) <30 mL/min/1.73 m2 at Week -5 (Visit S1) (Levey 2006).   
Note:  At the discretion of the investigator, the screening period may be extended up to 4 weeks for a 
single repeat eGFR.  For those patients who have a repeat eGFR, the repeat value should be obtained 
between Visits S1 and S2 and will be used to determine eligibility. 
3. Body mass index (BMI) ≥50 kg/m2 
4. Recent (within 3 months prior to the screening visit [Week -5 (Visit S1)] or between screening and 
randomization visits) MI, unstable angina leading to hospitalization, uncontrolled, symptomatic 
cardiac arrhythmia (or medication for an arrhythmia that was started or dose changed within 3 months 
of screening), CABG, PCI, carotid surgery or stenting, cerebrovascular accident, transient ischemic 
attack (TIA), endovascular procedure or surgical intervention for peripheral vascular disease or plans 
to undergo a major surgical or interventional procedure (eg, PCI, CABG, carotid or peripheral 
revascularization).  Patients with implantable pacemakers or automatic implantable cardioverter 
defibrillators may be considered if deemed by the Investigator to be stable for the previous 3 months. 
5. Uncontrolled hypertension, defined as sitting systolic blood pressure (SBP) ≥160 mmHg and diastolic 
blood pressure (DBP) ≥100 mmHg after sitting quietly for 5 minutes.   
Note: If the initial blood pressure (BP) values meet or exceed the specified level, an additional BP 
assessment may be completed.  If the systolic or the diastolic values continue to meet or exceed the 
threshold, the patient may not continue screening.  However, at the discretion of the Investigator, the 
screening period (between Visits S1 and S2) may be extended up to 4 weeks to allow for a repeat 
qualifying BP assessment following adjustment of BP medication(s), provided that the patient has 
been on a stable dose of the BP medication for a minimum of 2 weeks prior to randomization and the 
repeat BP measurements do not meet the exclusion criteria. 
6. Hemoglobin A1C (HbA1C) ≥10% at Week -5 (Visit S1) 
7. Uncontrolled hypothyroidism, including thyroid-stimulating hormone (TSH) >1.5 × the upper limit of 
normal (ULN) at Week -5 (Visit S1). Patients stabilized on thyroid replacement therapy for at least 
6 weeks prior to randomization are allowed.

(unconjugated) bilirubin will be obtained and if consistent with Gilbert’s disease or if the patient 
has a history of Gilbert’s Disease, the patient may be enrolled in the study.    
Note: At the discretion of the investigator, a single repeat of ALT and/or AST may be completed 
prior to randomization.  For those patients who have a repeat ALT and/or AST, the repeat value 
will be used to determine eligibility.  Also, if test for hepatitis C antibody is positive, but reflexive 
test for Hepatitis C ribonucleic acid (RNA) is negative, patient can be enrolled.  
9. Gastrointestinal conditions or procedures (including weight loss surgery; eg, Lap-Band® or gastric

Safety and Monitoring: 
Monitoring and Management Plans for Lipid Elevations: 
Elevated LDL-C—Adjunctive Therapy: 
An adjunctive therapy plan is in place for those patients whose LDL-C values meet the protocol-defined 
LDL-C threshold criteria. Post-randomization, LDL-C results will be masked to investigators in order to 
maintain the blind; however, the following thresholds have been set to notify investigators and provide an 
opportunity to adjust the patient’s standard of care regimen.  
• 
Beginning at Week 24 (Visit T5) visit and for the duration of the study, the central laboratory will 
notify the investigator when the patient’s LDL-C value is >170 mg/dL (4.4 mmol/L) and ≥25% 
from the patient’s baseline value at Week 0 (Visit T1) 
• 
Upon receiving notification from the central laboratory that the patient has met or exceeded the 
threshold criteria for LDL-C, the investigator will initiate the following adjunctive therapy plan: 
- Patients will be scheduled to return to the clinic within 1 week for a repeat fasting blood 
lipid sample to confirm that the LDL-C value meets the threshold criteria  
- After confirming that the LDL-C value meets or exceeds the threshold criteria, the 
investigator will adjust the patient’s lipid-lowering treatment regimen per standard-of-
care and local practice, with the exception of simvastatin at doses ≥40 mg/day and the 
fibrate gemfibrozil. The patient’s LDL-C will be re-evaluated at the next scheduled clinic 
visit as defined in the Schedule of Visits (Appendix 1). 
- The initiation of any new or dose changes of any lipid-lowering treatment will be 
documented on the electronic case report form (eCRF) as a concomitant medication with 
the associated start date 
- Patients who have their lipid-lowering treatments modified, including new medications or 
dosage changes to existing medications, should return to the clinic in 4 weeks after the 
modification to their lipid-lowering treatment for a routine safety laboratory assessment. 
Additional safety laboratory assessments may be conducted at the investigator’s 
discretion. 
- Adjunctive therapy medications will not be provided by the sponsor 
- Patients continuing to exceed the LDL-C threshold after maximizing the standard-of-care 
LDL-C-lowering therapy and, in the opinion of the investigator, require therapies that are 
prohibited by the protocol will be discontinued from IMP treatment and will be asked to 
continue to be followed for safety using the protocol-specified visit schedule. 
Monitoring and Management Plans for Triglyceride Elevations: 
Elevated Triglycerides: 
Patients may continue to use stable doses of TG-lowering medications during the study.  An adjunctive 
therapy plan is in place for those patients whose TG values meet the protocol-defined threshold criteria.  
Post-randomization, TG results will be masked to investigators in order to maintain the blind; however, a 
threshold has been set to notify investigators and provide an opportunity to adjust the patient’s standard of 
care regimen.  Beginning at Week 4 (Visit T2), if the TG level exceeds 1000 mg/dL (11.3 mmol/L) while 
on treatment, the investigator will receive notification from the central laboratory that the patient has met 
or exceeded the protocol-defined threshold criteria for TG.  The investigator will initiate the following 
plan:

Page 11 of 184 
• 
Any patient with TG >1000 mg/dL (11.3 mmol/L) will be reminded to fast for at least 10 hours 
and will return to clinic within 1 week for a repeat, fasting TG sample to confirm the TG value 
meets the threshold criteria  
• 
Any patient with a confirmed TG >1000 mg/dL (11.3 mmol/L) may initiate standard-of-care 
therapy (however, gemfibrozil may not be added) to lower TG using a patient-specific 
prescription.  The initiation of this medication will be documented on the case report form as a 
concomitant medication with the associated start date.  These medications will not be provided by 
the sponsor. 
• 
Patients continuing to exceed the TG threshold after maximizing the standard-of-care triglyceride-
lowering therapy will be discontinued from IMP treatment and will be asked to continue to be 
followed for safety using the protocol-specified visit schedule. 
Monitoring and Management of Potential AEs and Adverse Events of Special Interest (AESI) 
Adverse Events Associated with Experience with Bempedoic Acid to Date: 
Potential AEs: 
Based on findings in nonclinical models, potential AEs include reversible hypoglycemia and 
metabolic acidosis.  Patients will be educated on the signs and symptoms of hypoglycemia and asked 
to report the experienced signs and symptoms to the investigator.  Investigator confirmed occurrences 
of hypoglycemia will be reported as AEs.  Potential cases of reversible hypoglycemia and metabolic 
acidosis will be identified by routine safety monitoring of AEs and clinical safety laboratories. 
Musculoskeletal Safety: 
Patients with CK abnormalities will also be reviewed for any other lab changes, such as creatinine, 
and any reported AEs or SAEs.  Musculoskeletal events will be identified and evaluated by routine 
safety monitoring of PE findings and AEs.  
Diabetes and Hyperglycemia: 
Cases of new onset of diabetes will be recorded as AEs.  Clinical laboratories, including HbA1C and 
glucose will also be evaluated across treatment groups during this study and all ongoing studies to 
identify potential cases of new onset of diabetes  
Neurocognitive Events: 
Neurocognitive events will be identified and evaluated by routine safety monitoring of PE findings 
and AEs. 
Clinical Endpoints: 
Clinical endpoints will be monitored and adjudicated by an independent expert CEC for this study and 
other ongoing studies in the bempedoic acid program. 
Routine cardiovascular monitoring will include review of cardiovascular AEs, SAEs, (both as 
adjudicated by the CEC), standard vital signs, and ECGs. 
Additional details regarding safety monitoring are included in Section 11.1.6.3.1 through 
Section 11.1.6.4.  
Further details on occurrence and monitoring are available in the Investigator’s Brochure (IB). 
Statistical methods: 
Sample Size 
The primary efficacy endpoint for this study is the percent change from baseline to Week 12 in LDL-C.   
The sample size of 500 randomized patients in the bempedoic acid 180 mg group and 250 randomized 
patients in the placebo group is expected to provide more than 95% power to detect a difference of 15% 
in the percent change from baseline to Week 12 in LDL-C between the bempedoic acid treatment group 
and the placebo group.  This calculation is based on a 2-sided t-test at the 5% level of significance 
(α = 0.05) and a common standard deviation of 15%.  The sample size of 500 randomized patients in the 
bempedoic acid 180 mg group and 250 randomized patients in the placebo group gives a total study

sample size of 750.  
Analysis Populations 
The Full Analysis Set (FAS), used for all of the efficacy summaries and analyses, is defined as all 
randomized patients.  The FAS is also known as the intention-to-treat (ITT) set of patients.  Patients in the 
FAS will be included in their randomized treatment group, regardless of their actual treatment.  
The Safety Population (SP), used for all of the safety summaries, is defined as all randomized patients 
who received at least 1 dose of study medication.  Patients in the SP will be included in the treatment 
group that they actually received, regardless of their randomized treatment.  
Disposition and Baseline Characteristics 
Disposition, including reason for withdrawal from the study, will be summarized by treatment group. 
Demographic information and patient characteristics including, but not limited to, gender, race, age, and 
baseline vital signs will also be summarized by treatment group. 
Primary Endpoint  
The primary efficacy endpoint is the percent change from baseline to Week 12 in LDL-C.  The primary 
efficacy endpoint will be analyzed using analysis of covariance (ANCOVA), with treatment group, CV 
risk (ASCVD only; HeFH with or without ASCVD) and baseline statin intensity (high intensity, moderate 
intensity, low intensity) as factors and baseline LDL-C as a covariate.  Baseline LDL-C is defined as the 
mean of the LDL-C values from Week -1 (Visit S3) and predose Day 1/Week 0 (Visit T1).  The 
ANCOVA will be performed using the FAS, with patients included in their randomized treatment group 
regardless of the treatment they actually received.  Two methods for data handling will be used:  the first 
is observed case data only, while the second will involve specification of the missing data mechanism 
using a pattern mixture model (PMM).  The primary analysis will be that from the PMM, while the 
observed case analysis will be used as confirmatory.  The PMM will be used to specify different 
imputation strategies depending on whether the patient is still on study treatment.  Imputed datasets will 
be analyzed using ANCOVA with treatment group, CV risk (ASCVD only; HeFH with or without 
ASCVD) and baseline statin intensity (high intensity, moderate intensity, low intensity) as factors and 
baseline LDL-C as a covariate.  Approximately 200 imputed datasets will be created, with results from 
the analysis of each imputed dataset combined using Rubin’s method.  For each type of ANCOVA 
(observed case; imputation via PMM), the least squares mean (LSM) and standard error (SE) will be 
provided for both treatment groups, along with the placebo-corrected LSM, its 95% confidence interval 
(CI) and associated p-value. 
Secondary and Tertiary Efficacy Endpoints 
Secondary efficacy endpoints are also of interest for this study, in terms of controlling the overall Type I 
error rate.  A gatekeeping or stepdown approach will be used to test the primary efficacy endpoint and 
then specific secondary efficacy endpoints sequentially in order to preserve the study-wise Type I error 
rate.  The sequence for the stepdown procedure in this study is as follows: 
1. Test the primary efficacy endpoint: percent change from baseline to Week 12 in LDL-C  
2. Test the percent change from baseline to Week 24 in LDL-C 
3. Test the percent change from baseline to Week 12 in non-HDL-C 
4. Test the percent change from baseline to Week 12 in TC 
5. Test the percent change from baseline to Week 12 in apoB 
6. Test the percent change from baseline to Week 12 in hs-CRP   
In this hierarchical testing structure, each hypothesis is tested at a significance level of 0.05, two-sided. 
Statistical significance at each step is required in order to test the next hypothesis.  If the primary endpoint 
meets the criteria for statistical significance, then the percent change from baseline to Week 24 in LDL-C 
will be tested; and so forth.  
Percent change from baseline to Week 24 in LDL-C; absolute change from baseline to Weeks 12, 24,

and 52 in LDL-C; percent change from baseline to Weeks 12, 24, and 52 in HDL-C, non-HDL-C, TG, 
TC, apoB, and hs-CRP will each be analyzed using ANCOVA with treatment group, CV risk (ASCVD 
only; HeFH with or without ASCVD) and baseline statin intensity (high intensity, moderate intensity, low 
intensity) as factors and the relevant baseline as a covariate.  Baseline for HDL-C, non-HDL-C, TG, and 
TC will be defined as the mean of the lipid values from Week -1 (Visit S3) and predose Day 1/Week 0 
(Visit T1).  If a repeat lipid measurement is performed at Week -1 (Visit S3), then baseline will be the 
mean of the lipid values from the second Week -1 assessment and predose Day 1/Week 0 (Visit T1).  
Baseline for apoB and hs-CRP will be defined as the predose Day 1/Week 0 (Visit T1) value.  Each 
ANCOVA will be performed using the FAS, with patients included in their randomized treatment group 
regardless of the treatment they actually received.  For each lipid parameter and analysis time point, the 
LSM and SE will be provided for both treatment groups, along with the placebo-corrected LSM, its 95% 
CI and associated p-value. 
For all continuous efficacy endpoints (percent change from baseline in LDL-C, HDL-C, non-HDL-C, TC, 
TG, apoB, and hs-CRP; change from baseline in LDL-C; to Weeks 12, 24, and 52, as appropriate), the 
ANCOVA assumption of normality will be assessed.  If non-normality of the data is found at any time 
point for any parameter, either the data will be transformed so that it is normally distributed or a 
nonparametric test will be used instead of the planned ANCOVA. 
In addition, a summary of percent change from baseline to Week 12 LDL-C using the FAS, excluding 
patients who received additional lipid-lowering therapy by that time point (by Week 12 for the Week 12 
time point), will be provided. Percent change from baseline to Weeks 24 and 52 on LDL-C will be 
analyzed similarly, with patients in the FAS who did not receive additional LDL or triglyceride-lowering 
therapy by that time point (by Week 24 for the Week 24 analysis by Week 52 for the Week 52 analysis) 
included in the analyses.  Output from each time point will include the LSM and SE for each treatment 
group, as well as the placebo-correct LSM, 95% CI, and p-value. 
Additional post-randomization adjunctive lipid-modifying therapy 
The number and percent of patients in each treatment group requiring additional (post-randomization) 
adjunctive lipid-modifying therapy will be summarized. Medications and the reasons for their additional 
treatment (hyperlipidemia vs. hypertriglyceridemia) will be summarized separately. 
Safety Analyses 
The summarization of AEs will include TEAEs, defined as AEs with an onset date on or after initiation of 
study treatment.  TEAEs and SAEs will be summarized by system organ class (SOC), severity, and 
relationship to study drug for each treatment group.  These AE summaries will include cumulative 
incidence (percent of patients experiencing the AE) and patient-year adjusted incidence rates.  If 
appropriate, absolute and relative risk differences will be calculated using both cumulative incidence and 
incidence rates.  Deaths, withdrawal from study treatment due to AEs, and withdrawal from the study due 
to AEs will each be summarized by treatment group. 
Clinical safety laboratories, including hematology, blood chemistry, coagulation, HbA1C, glucose, and 
urinalysis; PE findings; vital signs; ECG readings; and weight will be summarized by the value and by 
change from baseline in the value (where appropriate) at each postbaseline time point. 
Hepatic Safety 
Liver-associated enzymes and TB will be summarized by the value and change from baseline in the value, 
by treatment group and visit. In addition, the number and percent of patients with abnormal values for 
ALT, AST, and TB will be summarized.  These summaries of patients with abnormal values will be 
performed overall; by normal baseline; and by abnormal baseline for each of ALT, AST, and TB.  Hy’s 
law criteria (≥3 × ULN for either ALT or AST, with accompanying TB >2 × ULN or patient’s baseline) 
will also be applied to the data; any potential Hy’s law cases will be listed separately.  In the case of 
patients with Gilbert’s disease, TB will be fractionated and the determination of 2 × ULN based upon 
direct (conjugated) bilirubin.

AEs of muscle-related symptoms will be summarized by treatment group.  CK levels will be summarized 
by the value and change from baseline in the value, by treatment group and visit.  In addition, the number 
and percent of patients with abnormal CK values will be summarized.  These summaries of patients with 
abnormal CK will be performed overall; by normal baseline CK; and by abnormal baseline CK.  
Diabetes and Hyperglycemia  
Cases of new onset of diabetes will be recorded as AEs and will be summarized using the appropriate 
SOC.  These events will be summarized by severity and relationship to study drug for each treatment 
group.  Glucose and HbA1C will be monitored at baseline and at Weeks 12 and 24and be summarized. 
Renal Safety 
Baseline eGFR will be summarized by treatment group for actual value and for baseline eGFR categories.  
Shift tables of eGFR category from baseline over the study, will be provided by treatment group.  Shift 
tables of urine protein (negative/positive) from baseline over the study, will be provided by treatment 
group.  Values of CK over the study will be summarized by treatment group and by baseline eGFR 
category.  Finally, muscle-related AEs will be summarized by treatment group and by baseline eGFR 
category. 
Neurocognitive Events 
Neurocognitive events will be identified and evaluated by routine safety monitoring of PE findings and 
AEs.  Summarization of neurocognitive events will occur using prespecified Medical Dictionary for 
Regulatory Activities (MedDRA) terms and will be performed by SOC, severity, and relationship to study 
drug for each treatment group. 
Clinical Endpoints 
Clinical endpoints using standardized definitions will be adjudicated by an independent blinded expert 
CEC for all ongoing Phase 3 studies in the bempedoic acid program.  Investigator-reported clinical 
endpoints and adjudicated clinical endpoints will be summarized by event type and treatment group.  
Additional details regarding the clinical endpoints and their definitions will be included in CEC Charter.   
PK and Other biomarkers 
PK plasma concentrations of ETC-1002 and its metabolite ESP15228 will be summarized prior to dose at 
Weeks 24 and 52.

INTRODUCTION 
4.1. 
Lipid-Regulating Drugs and Cardiovascular Disease  
Bempedoic acid (ETC-1002) is an inhibitor of adenosine triphosphate-citrate lyase (ACL) 
(adenosine triphosphate [ATP] citrate lyase), an enzyme upstream of 3-hydroxy-3-methylglutaryl 
coenzyme A (HMG-CoA) reductase in the cholesterol biosynthesis pathway.  It is an oral first-
in-class small molecule designed to lower low-density lipoprotein cholesterol (LDL-C) levels in 
patients with high cardiovascular (CV) risk unable to meet their treatment goals with currently 
available lipid-lowering therapies. 
Hyperlipidemic patients at high CV risk due to either heterozygous familial 
hypercholesterolemia (HeFH) and/or established atherosclerotic cardiovascular disease 
(ASCVD) unable to meet their LDL-C treatment goals with currently available therapies are the 
target patient populations for this study.  
Elevated LDL-C is a major modifiable risk factor for the development of atherosclerosis and 
ASCVD (Sharrett 2001).  Despite aggressive interventional and pharmacologic therapies, CV 
disease is the number 1 cause of death globally (WHO 2015).  An estimated 17.5 million people 
died from CV diseases in 2012, representing 31% of all global deaths.  Of these deaths, an 
estimated 7.4 million were due to coronary heart disease (CHD) and 6.7 million were due to 
stroke (WHO 2015).  Cardiovascular disease remains the leading cause of death among 
Europeans, Americans, and around the world.  The Global Burden of Disease study estimated 
that 29.6% of all deaths worldwide (approximately 15.6 million deaths) were caused by CV 
disease in 2010, more than all communicable, maternal, neonatal and nutritional disorders 
combined, and double the number of deaths caused by cancers (Nichols 2014).  In the United 
States (US), based on 2011 death rate data, more than 2150 Americans die from CV diseases 
daily, an average of 1 death every 40 seconds.  Approximately 155,000 Americans dying from 
CV disease are less than 65 years of age.  In 2011, 34% of deaths due to CV disease occurred 
prior to the age of 75 years, less than the current 78.7-year average life expectancy (Mozffarian 
2015).  
Patients with documented ASCVD are at very high risk for events and require intensive 
pharmacologic intervention (Stone 2014).  For a variety of reasons, many with ASCVD are 
unable to attain aggressive LDL-C treatment goals despite the addition of lipid-lowering agents 
to maximally tolerated statin therapy (Jacobson 2014).  
Familial hypercholesterolemia refers to individuals with extremely elevated LDL-C due to 
underlying genetic mutations of the LDL receptor (LDLR), apolipoprotein B (apoB), and 
proprotein convertase subtilisin/kexin type 9 (PCSK9) (FH Foundation 2015).  In adult HeFH 
patients, LDL-C usually exceeds 190 mg/dL (4.9 mmol/L) and can be as high as 400 mg/dL 
(10.4 mmol/L).  HeFH is the most common form of the disease with a prevalence of 
approximately 1 in 300 to 500 persons worldwide and as high as 1 in 100 persons in some 
populations (NORD 2015).  Patients with HeFH inherit a genetic mutation from 1 parent.  
Inheritance is generally via an autosomal-dominant mechanism (Robinson 2013).  HeFH 
increases the risk of atherosclerosis leading to CV events.  The mean age for the onset of CV

disease is relatively young, at 42 to 46 years in men and 51 to 52 years in women (Robinson 
2013).  The cumulative risk of experiencing a coronary event by the age of 60 years without 
effective treatment is at least 50% in men and approximately 30% in women with a marked 
increase in postmenopausal women.  Before effective treatment with statins became available, 
mortality from coronary disease was increased by nearly 100-fold in young adults 20 to 39 years 
of age, and approximately 4-fold for patients aged 40 to 59 years (Neil 2008).  The National 
Lipid Association (NLA) recommends achievement of ≥50% reduction in LDL-C in adult 
patients using statins.  HeFH patients at even higher risk for CV disease (such as those with 
established ASCVD, diabetes, smoking, family history, and other risk factors) have a treatment 
goal of ≤70 mg/dL (1.8 mmol/L).  Those unable to achieve these treatment goals with maximally 
tolerated statin therapy require additional lipid-lowering therapy and still may be unable to reach 
LDL-C treatment goals.  
Lowering LDL-C is the primary therapeutic lipid target in ASCVD and HeFH patients 
(Goldberg 2011).  LDL-C is largely accepted as a valid surrogate endpoint of CV events by 
clinicians and regulatory authorities (Stone 2014).  Long-term elevations in LDL-C lead to 
progressive accumulation of atherosclerotic lesions in the walls of arteries that require long-term 
management.  While lifestyle changes are the primary intervention, these measures rarely reduce 
plasma LDL-C by >15%.  Particularly in ASCVD and HeFH patients, pharmacologic treatments 
are required to adequately treat hyperlipidemia (Pollex 2008).  Evidence supporting LDL-C as a 
therapeutic target and surrogate for CV outcomes comes from interventional studies with 
LDL-C-lowering therapies, epidemiological studies, genetic variants (both gain of function and 
loss of function). Large randomized clinical studies aimed at lowering LDL-C show a consistent, 
log-linear relationship between LDL-C reduction and CV risk reduction, independent of the way 
LDL-C lowering was achieved based on mechanism of action (Kathiresan 2008; Baigent 2010; 
Robinson 2005; Stamler 1986).  A published patient-level meta-analysis including 26 trials and 
more than 160,000 participants, showed a consistent relationship between LDL-C reduction and 
CV outcomes (Baigent 2010).  This analysis showed that with a 1 mmol/L reduction in LDL-C 
associated with a 22% reduction in the 5-year incidence of major coronary events, 
revascularizations, and ischemic strokes.  Intensive statin therapy relative to low/moderate 
intensity statin treatment produces greater benefit in patients at high CV risk (Cannon 2004).  
Unfortunately, some patients are unable to take high intensity statins due to dosing limits based 
on co-morbidities, contraindications, and/or tolerance (Jacobson 2014).  Nonstatin therapies may 
provide additional lowering of CV risk as demonstrated in the IMPROVE-IT trial which added 
ezetimibe to statin therapy (Cannon 2015).  
Patients with ASCVD and HeFH on maximally tolerated lipid-lowering therapy including 
maximally tolerated doses of statins who require additional lipid-lowering therapy have an unmet 
medical need.  ETC-1002 may offer a once daily option for these patients.  The oral route of 
administration may be preferable to injectable biologic therapy for some patients.  Bempedoic 
acid has been well tolerated to date and Phase 2 data demonstrate significant LDL-C lowering, 
prompting further evaluation in Phase 3 clinical studies.

4.2. 
Background on Bempedoic Acid 
4.2.1. 
Mechanism of Action 
Bempedoic acid is a first-in-class small molecule inhibitor of ACL, an enzyme upstream of 
HMG-CoA in the cholesterol biosynthesis pathway.  Bempedoic acid is a prodrug that requires 
activation in liver to ETC-1002-co-enzyme A (ETC-1002-CoA), which mediates competitive 
inhibition of ACL.  Inhibition of ACL by ETC-1002-CoA decreases cholesterol synthesis in liver 
leading to increased LDLR expression and LDL particle clearance from the blood.  Therefore, 
inhibition of ACL by ETC-1002-CoA reduces LDL-C via the same pathway as HMG-CoA 
reductase inhibition by statins. 
An important differentiating feature of bempedoic acid is that, unlike statins, it does not inhibit 
cholesterol synthesis in skeletal muscle.  The enzyme required to convert bempedoic acid to 
ETC-1002-CoA is not present in skeletal muscle.  Therefore, bempedoic acid is not anticipated 
to mediate the adverse effects associated with inhibition of biological intermediates within the 
cholesterol biosynthesis pathway in skeletal muscle; however, the safety of bempedoic acid and 
its metabolites regarding human skeletal muscle is not yet established. 
4.2.2. 
Nonclinical Experience 
The primary pharmacology of bempedoic acid was evaluated in several well-characterized and 
predictive rodent models of dyslipidemia.  In these studies, bempedoic acid lowered LDL-C and 
triglycerides (TGs) and increased high-density lipoprotein cholesterol (HDL-C).  In a study of 
cholesterol-fed LDLR-deficient mice, bempedoic acid substantially slowed the progression of 
atherosclerosis in a dose-related manner. 
Results of the safety pharmacology studies did not identify any significant risks for subjects over 
the range of exposures intended for clinical studies. 
In toxicology studies, evaluations of bempedoic acid in mice, rats, and monkeys in oral studies 
up to 52 weeks in duration have been completed.  No significant central nervous system (CNS), 
respiratory, or CV liabilities were identified.  Target organs identified in repeat-dose studies 
were liver in rats and liver and kidney in monkeys, and changes were reversible following 
cessation of treatment.  Changes in clinical laboratory parameters indicative of hepatic and renal 
function were observed in animals at doses lower than those associated with frank toxicity.  
Routine clinical laboratory parameters will continue to be monitored carefully in clinical trials. 
Bempedoic acid is nonmutagenic and nonclastogenic in both in vitro and in vivo genetic 
toxicology assays.  
In the pivotal 26-week rat study, the no-observed-adverse-effect level (NOAEL) dose was 
30 mg/kg/day in rats and the corresponding area under the curve during 24 hours (AUC0-24) 
values of the sum of ETC-1002 and ESP15228 were up to 528 µg⋅hr/mL.  In the pivotal 52-week 
monkey study, the NOAEL dose was 60 mg/kg/day and the corresponding AUC0-24 values of the 
sum of ETC-1002 and ESP15228 were up to 4760 µg⋅hr/mL. 
In vitro studies indicated that bempedoic acid is neither an inhibitor nor inducer of major 
cytochrome P450 (CYP) enzymes at clinically relevant plasma concentrations.  In addition, 
ETC-1002 bempedoic acid does not appear to inhibit major drug transporters.

4.2.3. 
Previous Human Experience 
Bempedoic acid has been evaluated in 15 completed clinical studies (nine Phase 1 and six 
Phase 2), with over 700 subjects receiving bempedoic acid doses from 2.5 mg/day up to 
240 mg/day (multiple doses) for up to 12 weeks.  All multiple-dose studies have demonstrated 
consistent, clinically meaningful LDL-C lowering with bempedoic acid treatment and have 
shown a positive safety profile.  This efficacy was observed across a range of patient 
populations, including those with primary hyperlipidemia and mixed dyslipidemia, some of 
whom also reported type 2 diabetes mellitus (T2DM), CHD, and/or statin intolerance.  In 
addition, a positive benefit/risk profile is shown across a range of low and moderate dose statins 
and ezetimibe. 
In both single- and multiple-dose studies, bempedoic acid is well absorbed (with a time to peak 
maximum concentration [Cmax] of approximately <4 hours).  The Cmax of ETC-1002 and 
ESP15228 increased in proportion to increasing dose; and the area under the concentration-time 
curve (AUC) showed slightly more than dose-proportional increases for ETC-1002 with 
increasing dose, but proportional increases in AUC were observed with ESP15228.  The terminal 
elimination half-life (t½) ranged from 15 to 27 hours for ETC-1002 and 20 to 33 hours for 
ESP15228. 
A study to assess the effect of a high-fat, high-calorie meal on the bioavailability of ETC-1002 
following administration of 180-mg tablet relative to the fasted state, the bioavailability of 
180-mg capsules relative to one 180-mg tablet in the fasted state, and the bioavailability of three 
60-mg tablets relative to one 180-mg tablet has completed (1002-016).  A high-fat meal has no 
effect on the PK of ETC-1002 180-mg tablet; ETC-1002 PK are equivalent whether taken in the 
fasting or fed state.  The evaluation of the tablet formulation that will be used in Phase 3 
demonstrates similar PK characteristics to the capsule formulation utilized in Phases 1 and 2.  
The PK following three 60-mg tablets was similar to one 180-mg tablet.  Only the 180-mg tablet 
is planned for use in Phase 3.  
Two studies evaluated clinical drug-drug interaction using bempedoic acid 240 mg and showed 
less than a 2-fold increase in the exposure of atorvastatin 10 mg, simvastatin 20 mg, pravastatin 
40 mg, and rosuvastatin 10 mg (Studies 1002-007 and 1002-012).  Likewise, when bempedoic 
acid 180 mg was dosed in combination with high-dose statins (atorvastatin 80 mg, pravastatin 
80 mg, rosuvastatin 40 mg, and simvastatin 40 mg), mean exposure of these statins increased 
between approximately 1.4- and 2-fold (1002-037).  
No drug interaction occurred between daily ETC-1002 180 mg and metformin in patients with 
T2DM.  A Phase 2 study showed no effect of ezetimibe 10 mg on steady-state trough ETC-1002 
plasma concentrations in 40 patients with hypercholesterolemia randomized to receive 
ETC-1002 plus ezetimibe (Study 1002-008).  Results of a drug interaction study in 19 patients 
(16 evaluable for PK) with the oral contraceptive Ortho-Novum 1/35 in healthy women 
demonstrate no effect of daily ETC-1002 180 mg on ethinyl estradiol or norethindrone exposure 
(Study 1002-017).

The results of the thorough QT/QTc (TQT) study (1002-022) showed no significant change in 
QTc.  Following daily bempedoic acid 240 mg for 9 days, bempedoic acid does not prolong QT 
interval duration and has no clinically significant effect on heart rate and PR and QRS intervals. 
Occurrences of treatment-emergent adverse events (TEAEs), withdrawals due to adverse events 
(AEs), and treatment-related AEs were similar across groups receiving bempedoic acid, placebo 
or an active comparator, ezetimibe.  Across the 15 clinical studies, the most frequently reported 
TEAEs included musculoskeletal and connective tissue disorders (back pain, pain in extremity, 
myalgia, arthralgia, muscle spasms), nervous system disorders (headache), gastrointestinal (GI) 
disorders (nausea, diarrhea), and infections and infestations.  Overall, AEs were generally 
reported with similar incidence between treatment groups; however, the incidence of headache 
was higher with bempedoic acid than placebo.  AEs were typically characterized as mild or 
moderate.  Treatment-emergent serious adverse events (SAEs) were reported for 11 subjects.  
There has been 1 death: an event of sudden death (cause unknown) in a bempedoic acid-treated 
subject in Clinical Study 1002-008. The event was assessed by the investigator as severe and as 
possibly related to study treatment.  The rationale for the investigator assessment was that a 
relationship to bempedoic acid could not be ruled out given the temporal nature of the event.  A 
full narrative for this event is presented in the IB. 
In general, laboratory results showed no clinically significant trends.  
4.2.4. 
Dose Selection 
Doses of bempedoic acid ranging from 40 to 240 mg/day have been evaluated in the Phase 2 
program.  Based on data from the integrated analysis of safety and efficacy, observed values and 
percent change from baseline in the primary efficacy endpoint, LDL-C together with a positive 
safety profile, support the choice of the 180-mg dose for the Phase 3 studies.  An integrated 
analysis of six Phase 2 studies resulted in placebo-adjusted least square (LS) means for percent 
change from baseline of approximately 32% with bempedoic acid 180 mg monotherapy, 50% 
with bempedoic acid 180 mg + ezetimibe 10 mg, and 22% for 180 mg on top of stable statin 
therapy.  The 180-mg dose was noted to have an excellent safety profile.  Overall, balancing 
efficacy and safety the 180-mg dose was chosen for the Phase 3 program. 
4.2.5. 
Background Therapy 
Bempedoic acid in this study is currently being evaluated as an add-on to lipid-modifying 
therapy in high-risk patients (ie, those with HeFH and/or ASCVD) who have not achieved their 
LDL-C goal despite maximally tolerated lipid-modifying therapy.  
4.2.6. 
Risk Benefit Summary 
To date, the nonclinical and clinical data indicate that bempedoic acid has a favorable risk-
benefit profile.  The ability of bempedoic acid to achieve clinically meaningful LDL-C-lowering 
responses while demonstrating a favorable tolerability profile in a variety of patient populations 
supports continued development of bempedoic acid, an oral ACL inhibitor, in Phase 3 studies.

experience.

INVESTIGATIONAL PLAN 
6.1. 
Overall Study Design 
This is a Phase 3, long-term randomized, double-blind, placebo-controlled, parallel group, study 
evaluating the efficacy of bempedoic acid in high CV risk patients with hyperlipidemia (patients 
with underlying HeFH and/or ASCVD) who are not adequately treated with their maximally 
tolerated lipid-modifying therapy.  Maximally tolerated lipid-modifying therapy includes a 
maximally tolerated statin alone or in combination with other lipid-modifying therapies (eg, 
ezetimibe, fibrates [except gemfibrozil, as per co-administration instructions defined in the statin 
label] and PCSK9 inhibitors).  A patient’s maximally tolerated lipid-modifying therapy will be 
determined by the investigator using their medical judgment and available sources, including the 
patient’s self-reported history of lipid-modifying therapy.   
The study will be conducted at approximately 125 clinical sites in the North America and 
Europe. 
Screening Week -5 (Visit S1) will be approximately 5 weeks prior to randomization, but can be 
extended for an additional 4 weeks if needed to adjust background medical therapy or for other 
reasons as specified in the protocol.  Eligible patients will return to the clinical site at Week -4 
(Visit S2) to initiate administration of single-blind (patient only) placebo.  Eligible patients will 
return at Week -1 (Visit S3) for lipid and safety laboratories and an assessment of tolerability and 
study drug adherence.  Patients who are deemed not eligible for randomization at any point 
during screening will be notified by clinical site personnel regarding their eligibility status and 
considered screen failures.  As necessary, for reasons of safety if a patient begins the run-in 
period but screen fails prior to randomization, the patient may be asked to return to the clinical 
site for further evaluation and follow-up of AEs. 
Patients on maximally tolerated lipid-modifying therapy, as determined by the investigator, will 
be stratified based on the patient’s CV risk (ASCVD alone; HeFH with or without ASCVD) and 
baseline statin intensity (high intensity statin, moderate intensity statin, low intensity statin) for a 
total of 6 strata.  Statin intensity categories and randomization strata are defined in Table 2 and 
Table 3 below, respectively. Intensity category is based on average daily dose.

Approximately 750 eligible patients will be randomized 2:1 on Day 1 (Visit T1) to receive either 
bempedoic acid 180 mg (n = 500), or placebo (n = 250) once daily for 52 weeks.  Randomized 
patients will return for clinic visits at Week 4 (Visit T2), Week 12 (Visit T4), Week 24 
(Visit T5), and Week 52 (Visit T7).  A phone visit will occur at Week 8 (Visit T3) and Week 36 
(Visit T6).   
Patients who withdraw from investigational medicinal product (IMP) treatment will be asked to 
continue to be followed for safety using the protocol-specified visit schedule.  For details of 
study assessments, see the Schedule of Events in Appendix 1. 
An independent expert Data Monitoring Committee (DMC) will formally review accumulating 
unblinded safety and efficacy data from this and other ongoing studies of bempedoic acid.  A 
blinded independent expert Clinical Events Committee (CEC) will adjudicate designated clinical 
endpoints, including all major adverse cardiac events (MACE) and non-MACE endpoints 
defined as:  CV death (MACE), non-CV death (non-MACE), nonfatal myocardial infarction 
[MI] (MACE), nonfatal stroke (MACE), hospitalization for unstable angina (MACE), coronary 
revascularization (MACE), non-coronary arterial revascularization (non-MACE), and

6.5. 
Number of Patients 
The study will enroll approximately 750 adult male and female HeFH and/or ASCVD patients 
with hyperlipidemia from approximately 125 clinical sites.  
6.6. 
Patient Identification Numbers 
A unique patient identification number will be assigned to each patient to identify each patient 
throughout the study and will be entered on all documentation.  If a patient is not eligible to 
receive treatment, or if a patient discontinues from the study, their patient identification number 
cannot be assigned to another patient.  
Patient identification numbers will be assigned sequentially by interactive web response system 
(IWRS) at the time of informed consent during the screening module transaction.  Screening and 
Placebo Run-in Period  
Screening will occur approximately 5 weeks prior to Day 1 (Visit T1) where the patient’s 
eligibility will be evaluated.  Eligible patients who are taking allowed concomitant medications 
must be on stable regimens as defined in Section 8.2.  At the investigator’s discretion, screening 
(time between visits S1 and S2) may be extended for an additional 4 weeks if needed to adjust 
background medical therapy or for other reasons as specified in the protocol.  Eligible patients 
will return to the clinical site at Week -4 (Visit S2) to initiate administration of single-blind 
(patient only) placebo.  Eligible patients will return at Week -1 (Visit S3) for lipid and safety 
laboratories and an assessment of tolerability and study drug adherence (see Section 7.1 and 
Section 7.2 for eligibility criteria).  Patients who are deemed not eligible for randomization at 
any point during screening will be notified by clinical site personnel regarding their eligibility 
status and considered screen failures.  As necessary, for reasons of safety if a patient begins the 
run-in period but screen fails prior to randomization, the patient may be asked to return to the 
clinical site for further evaluation and follow-up of AEs. 
6.6.1. 
Randomization and Treatment Period 
For patients who satisfy all entry criteria and complete the 1-week screening period and 4-week 
run-in period, randomization will occur and their randomization number will be assigned via 
IWRS at Week 0 (Visit T1).  Patients will be stratified on CV risk (HeFH and ASCVD 
diagnosis) and baseline statin intensity (high intensity statin, moderate intensity statin, low 
intensity statin), and randomized in a ratio of 2:1 to receive 1 of the 2 following treatments in a 
double-blind fashion: 
• Bempedoic acid 180-mg tablet 
• Matching placebo tablet 
For details regarding the randomization strata see Table 3.

of study drug.  Acceptable methods of birth control include: oral, implantable, 
injectable or topical birth control medications; placement of an intrauterine device 
(IUD) with or without hormones; barrier methods including condom or occlusive cap 
with spermicidal foam or spermicidal jelly; vasectomized male partner who is the sole 
partner for this patient; or true abstinence when this is in line with the preferred and 
usual lifestyle of the subject (periodic abstinence [eg, calendar, ovulation, 
symptothermal, postovulation methods], declaration of abstinence for the duration of 
the trial, and withdrawal are not acceptable methods of contraception). 
There are no protocol-specific birth control requirements for men with partners who are 
able to become pregnant. 
5. Fasting LDL-C (minimum of 10 hours) value at Week -5 (Visit S1) ≥100 mg/dL 
(2.6 mmol/L) and fasting LDL-C value at Week -1 (Visit S3) ≥70 mg/dL (1.8 mmol/L).  
6. Have high CV risk that is defined as either: 
• Diagnosis of HeFH.  Diagnosis must be made by either genotyping or by clinical 
assessment using either the World Health Organization (WHO) criteria/Dutch Lipid 
Clinical Network Criteria with a score that is >8 points (see Appendix 4) or the

[PCI] or coronary artery bypass graft [CABG] surgery) 
− Clinically significant CHD diagnosed by invasive or non-invasive testing (such as 
coronary angiography, stress test using treadmill, stress echocardiography or 
nuclear imaging) 
Documented CHD risk equivalents (includes 1 or more of the following criteria): 
− Symptomatic peripheral arterial disease (PAD) defined as 
○ Peripheral vascular disease with symptoms of claudication or resting limb 
ischemia with either ankle brachial index <0.9 performed by a vascular lab or

Note:  Patients with T2DM are allowed in this study; however, for this study 
T2DM is not considered a CHD risk equivalent 
7. Be on maximally tolerated lipid-modifying therapy, including a maximally tolerated 
statin either alone or in combination with other lipid-lowering therapies, at stable doses 
and regimens for at least 4 weeks prior to screening (6 weeks for fibrates; however, 
gemfibrozil is not allowed as per co-administration instructions defined in the statin 
label).  Maximally tolerated statin includes statin regimens other than daily dosing, 
including no to very low doses, but reasons for not using high-intensity statin dosing 
must be documented.  
A patient’s maximally tolerated lipid-modifying therapy will be determined by the 
investigator using their medical judgment and available sources, including the patient’s 
self-reported history of lipid-modifying therapy.

Note:  Patients can be on any available lipid-modifying therapy with the exception of the 
exclusions listed below as long as they have been stable for 4 weeks prior to Screening 
Visit S1 and are taken at a consistent time each day. In the case of PCSK9 inhibitor use, 
the patient must have received 3 stable doses.  It is important that lipid values are 
measured at PCSK9i trough levels.  Therefore, study visits should be scheduled in 
accordance with the patient’s PCSK9i injection regimen so that measurement of lipid 
values for all visits occurs before the PCSK9i injection but not greater than 48 hours 
before the next scheduled PCSK9 injection.  Patients who have discontinued 
investigational or commercial PCSK9 inhibitor must have had their last dose at least 
4 months prior to Screening Visit S1. 
7.2. 
Subject Exclusion Criteria 
Patients who meet any of the following criteria will not be randomized: 
1. Total fasting (minimum of 10 hours) triglyceride ≥500 mg/dL (5.6 mmol/L) at Week -5 
(Visit S1) 
Note:  TG may be repeated 1 time between Visits S1 and S2.  For those patients who 
have a repeat TG, the repeat value will be used to determine eligibility. 
2. Renal dysfunction or nephritic syndrome or a history of nephritis, including estimated 
glomerular filtration rate (eGFR) (using central laboratory determined Modification of 
Diet in Renal Disease [MDRD] formula) <30 mL/min/1.73m2 at Week -5 (Visit S1) 
(Levey 2006).   
Note: At the discretion of the investigator, the screening period may be extended up to 
4 weeks for a single repeat eGFR.  For those patients who have a repeat eGFR, the repeat 
value should be obtained between visits S1 and S2 and will be used to determine 
eligibility. 
3. Body mass index (BMI) ≥50 kg/m2 
4. Recent (within 3 months prior to the screening visit [Week -5 (Visit S1)] or between 
screening and randomization visits) MI, unstable angina leading to hospitalization, 
uncontrolled, symptomatic cardiac arrhythmia (or medication for an arrhythmia that was 
started or dose changed within 3 months of screening), CABG, PCI, carotid surgery or 
stenting, cerebrovascular accident, transient ischemic attack (TIA), endovascular 
procedure or surgical intervention for peripheral vascular disease or plans to undergo a 
major surgical or interventional procedure (eg, PCI, CABG, carotid or peripheral 
revascularization).  Patients with implantable pacemakers or automatic implantable 
cardioverter defibrillators may be considered if deemed by the Investigator to be stable 
for the previous 3 months. 
5. Uncontrolled hypertension, defined as sitting systolic blood pressure (SBP) ≥160 mmHg 
and diastolic blood pressure (DBP) ≥100 mmHg after sitting quietly for 5 minutes 
Note:  If the initial blood pressure (BP) values meet or exceed the specified level, an 
additional BP assessment may be completed.  If the systolic or the diastolic values 
continue to meet or exceed the threshold, the patient may not continue screening.  
However, at the discretion of the Investigator, the screening period (between Visits S1

following adjustment of BP medication(s), provided that the patient has been on a stable 
dose of the BP medication for a minimum of 2 weeks prior to randomization and the 
repeat BP measurements do not meet the exclusion criteria. 
6. Hemoglobin A1C (HbA1C) ≥10% at Week -5 (Visit S1) 
7. Uncontrolled hypothyroidism, including thyroid-stimulating hormone (TSH) >1.5 × the 
upper limit of normal (ULN) at Week -5 (Visit S1).  Patients stabilized on thyroid 
replacement therapy for at least 6 weeks prior to randomization are allowed. 
8. Liver disease or dysfunction, including:

reflex indirect (unconjugated) bilirubin will be obtained and if consistent with 
Gilbert’s disease or if the patient has a history of Gilbert’s Disease, the patient may be 
enrolled in the study. 
Note: At the discretion of the investigator, a single repeat of ALT and/or AST may be 
completed prior to randomization.  For those patients who have a repeat ALT and/or 
AST, the repeat value will be used to determine eligibility.  Also, if test for hepatitis C 
antibody is positive, but reflexive test for Hepatitis C ribonucleic acid (RNA) is negative, 
patient can be enrolled. 
9. Gastrointestinal conditions or procedures (including weight loss surgery; eg, Lap-Band®

If, in the opinion of the Investigator, the clinical observations in the study suggest that it may be 
unwise to continue, the Investigator may suspend or terminate the study after consultation with 
the Sponsor (or designee).  A written statement fully documenting the reasons for such a 
termination will be provided to the Sponsor (or designee) and the Institutional Review Board 
(IRB) or Independent Ethics Committee (IEC).  
The Sponsor has the right to terminate the study or to close a site and remove all study materials 
from the clinical site. A written statement will be provided to the Investigator, the IRB or IEC, 
and regulatory authorities, if required.  
Possible reasons for termination of the study at a clinical site include, but are not limited to: 
• Unsatisfactory enrollment with respect to quantity or quality 
• Inaccurate or incomplete data collection on a chronic basis 
• Falsification of records 
• Failure to adhere to the protocol 
• Lack of study oversight by the Principal Investigator and/or designee 
If any serious or nonserious AEs have occurred at such a clinical site, all documentation relating 
to the event(s) must be obtained.

8.3. 
Treatment Compliance 
Screening Compliance 
No study medication treatment will be given during the Screening period; therefore, compliance 
will not be assessed.  
Placebo Run-in and Treatment Period Adherence 
At Week -1 (S3) visit in the placebo run-in period and at each of the subsequent patient visits, 
designated clinical site staff will assess patient for placebo and/or IMP adherence by counting the 
number of tablets that are returned as unused and by querying the patient with regards to daily 
intake.  If the patient has not taken all doses of study drug as instructed, the patient will be 
queried for a reason, findings will be documented, and the patient will be counseled on the 
importance of carefully following all dosing instructions.  Factors contributing to poor adherence 
will be determined and, if possible, remedied.  Patients demonstrating poor adherence will 
continue to be counseled on the importance of carefully following all dosing instructions, but 
will not be removed from the study.  However, patients with ≤80% adherence over the entire 
Run-in Period and/or who experienced a study drug-related AE, will not go onto randomization.

8.4. 
Blinding 
Patients who satisfy all entry criteria during the screening and complete single-blind placebo 
run-in period and meet the lipid, safety, tolerability, and drug adherence measures will be 
randomized to a treatment group at Week 0 (Visit T1).  Patients on maximally tolerated lipid-
modifying therapy, as determined by the investigator, will be stratified based on the patient’s CV 
risk (ASCVD alone; HeFH with or without ASCVD) and baseline statin intensity (high intensity 
statin, moderate intensity statin, low intensity statin) for a total of 6 strata.  The Investigator or 
designee will contact IWRS at this visit to randomize the patient into the study.  The IWRS will 
determine the randomized treatment assignment based on their HeFH status and baseline statin 
use and dose and assign a randomization number and the appropriate study drug container via 
medication identification numbers (MED ID).   
After patients have been randomized, study drug, which is assigned by the IWRS, will be 
administered in a double-blind fashion.  The Sponsor, all clinical site personnel (Investigator, 
pharmacist, etc), and other vendor personnel will be blinded to the treatment group for each 
patient.  Patients will also be blinded to the treatment they receive.  Unblinded User(s) will be 
designated for each clinical site and at the sponsor (or designee) as needed.  Unblinded 
individuals will be provided IWRS access allowing them the ability to perform emergency 
unblinding of treatment for an individual patient.  An affirmative entry of the user’s login details 
will be required before the treatment group is displayed.  Unblinding at the clinical site for any 
other reason will be considered a protocol deviation.  Unblinded treatments for patients will 
NOT automatically discontinue the patient from the study.  To discontinue the patient from the 
study, the appropriate clinical site personnel will need to register the ‘discontinuation’ visit 
separately.  
Blinding of treatment must be maintained for all patients unless, in the opinion of the 
Investigator, the safety of the patient may be at risk.  Only under the rarest of circumstances 
should the Investigator consider breaking the blind and only when medical/supportive care 
cannot be provided without determining if the patient is receiving active drug treatment.  In the 
event that the blind needs to be broken prior to completion of the study, the Investigator should 
contact the appropriate Medical Monitor by telephone.  If the blind must be broken prior to 
consultation with the Medical Monitor, contact must be made within 24 hours of breaking the 
blind.  At the initiation of the study, the clinical site will be instructed on procedures for breaking 
the blind via the IWRS.  In all cases of breaking the blind, the Investigator must document in the 
patient’s medical record the date, time, and reason for breaking the blind, and the names of 
personnel involved.  
Limited vendors (ie, the bioanalytical laboratory and other vendor personnel, if any, that are 
responsible for PK analysis) will have access to the randomization codes to facilitate PK 
analytical work, and will be instructed to not communicate in any manner information associated 
with treatment assignment to any personnel at the clinical site, the Sponsor, or contract research 
organization (CRO).  
Post-randomization values for individual laboratory measures for LDL-C, TG, TC, HDL-C, 
non-HDL, apoB, and hs-CRP, including any plasma concentration of bempedoic acid and its 
metabolite that may inadvertently suggest treatment assignment will not be available to 
personnel from the clinical site, the patient, the Sponsor, and CRO.

An independent blinded expert CEC will adjudicate all clinical endpoints, including death, using 
standardized definitions.  Clinical endpoints will also be reported as SAEs.  Additional details 
and definitions will be provided in a CEC Charter. 
An independent DMC will monitor unblinded accumulating patient safety and efficacy data until 
the last patient has completed study treatment.  In addition, data on SAEs and deaths will be 
monitored by the DMC during this period.  At each DMC review, relevant unblinded safety and 
efficacy information from ongoing studies will be provided to the DMC by an independent, 
unblinded ICON programmer and statistician.  Additional details will be provided in a DMC 
Charter. 
8.5. 
Overdose 
There is no specific antidote for an overdose of bempedoic acid.  Management of an overdose 
should be focused on the treatment of symptoms.  These symptoms should be managed 
according to current standards of care with appropriate supportive measures.  Also 
discontinuation of study drug should be considered, as per medical judgment.

INVESTIGATIONAL MEDICINAL PRODUCT  
9.1. 
Investigational Medicinal Product Supply and Control 
The Sponsor will supply the IMP for this study.  The IMP for this study includes bempedoic acid 
(180-mg 
 tablets) and matching placebo (
 tablets).  IMP will be distributed 
and released in accordance with regional and local requirements during the conduct of the study. 
The MED ID number (an identifier on the study drug packaging) will be obtained via IWRS and 
used to select placebo for the single-blind placebo run-in period and double-blind IMP for the 
treatment period from available clinical supplies at the clinical site.  
A 35-day supply of single-blind placebo drug will be dispensed one time at Week -4 (Visit S2) 
for the 4-week placebo run-in period of the study.  Double-blind IMP will be dispensed in 100-
day supply increments to patients by appropriate clinical site personnel. Patients will receive one 
100-day supply bottle at Week 0 (Visit T1), Week 12 (Visit T4), and two 100-day supply bottles 
at Week 24 (Visit T5).  At Week 12, patients will return their first bottle and tablets will be 
counted by study personnel who will then dispense a second bottle.  At Week 24, tablets from 
the second bottle will be counted and the final 2 bottles dispensed.  At Week 52, tablets will be 
counted by study personnel from the 2 bottles dispensed at Week 24.  
Please see Pharmacy Manual for detailed storage requirements and management instructions. 
9.2. 
Administration of Investigational Medicinal Product 
Patients will be instructed to ingest, placebo starting at Visit S2 for the duration the placebo run-
in period and the IMP starting at Visit T1 for the duration of treatment period orally once daily 
(once every 24 hours) at approximately the same time each day with water.  IMP may be taken 
with or without food.  On clinic visit days, patients will be instructed to delay ingestion of IMP 
until all study procedures have been completed.  If a patient arrives at clinic on Visits T4 or T5 
or T7 without having fasted or having taken IMP before arriving at the clinic, reschedule the visit 
(the next day or as soon as possible) so that the fasting and dosing requirements have been met.  
Patients will be instructed to return all packaging and unused IMP at each clinic visit.  
If the patient forgets to take IMP at the usual time on nonclinic visit days, it may be taken up to 
12 hours later the same day.  After that time, the patient should not take IMP that day and should 
resume ingestion of IMP the following day.  If a patient fails to take IMP, details describing the 
reasons for nondosing should be documented in the patient’s medical records and eCRF.  Extra 
IMP (7 extra days per bottle) is provided and can be used, if needed, prior to the next visit or to 
replace a dose of IMP that cannot be used because it is lost or damaged.

STUDY PROCEDURES 
10.1. 
Informed Consent 
The patient must be adequately informed of the nature and risks of the study and understand the 
informed consent document (ICD).  No study-related procedure will be performed until the 
patient has been completely informed of the study, has freely consented to take part in the study, 
and has signed and dated an ICD approved by the Sponsor (or designee) and the IRB or IEC.   
10.2. 
Procedures and Schedule of Assessments 
Patients who provide informed consent and sign the ICD will be eligible to begin screening for 
the study.  The study is comprised of 3 distinct periods:  screening, single-blind placebo run-in 
and double-blind treatment.  
The schedule of study events is provided in Appendix 1.  However, a patient can be seen at any 
time for reasons of safety.  
Data will be captured on eCRFs.  Randomization, drug supply (re)ordering, and patient tracking 
will occur via IWRS.  Instructions for these systems will be provided separately. 
10.2.1. 
Screening Week -5 (Visit S1; Day -35 ± 7 days) 
The screening period will begin with a screening visit that will occur approximately 5 weeks 
prior to randomization.  Visit S1 will allow the Investigator to assess the patient’s preliminary 
eligibility.  After the patient provides written informed consent (see Section 10.1), the patient 
will undergo the following assessments and procedures at Visit S1: 
• Demographics 
• Clinically relevant medical history, including assessment of HeFH status and ASCVD  
• Concomitant and prohibited medication review 
• Height (cm), weight (kg), BMI  
• Vital signs  
• Clinical laboratory evaluations:  
− Hematology, blood chemistry, coagulation, and urinalysis 
− Basic fasting lipids (TC, calculated LDL-C, HDL-C, non-HDL-C, and TG) 
− 
HbA1C 
− TSH  
− FSH (in appropriate female patients) 
− Serum pregnancy test (on appropriate female patients) 
• Serology (including HBsAg, HCV)

• Review of all inclusion/exclusion criteria that can be assessed at this time 
• Conduct diet and exercise counseling 
• Contact IWRS to register the patient  
Patients who meet all enrollment criteria that can be assessed at Visit S1 will be instructed to 
continue their therapy(s) for lipid regulation and to maintain consistent diet and exercise patterns 
throughout the study.  Patients who fail to meet any entry criterion that can be assessed at 
Visit S1 are considered to be screen failures and are not required to return for additional visits 
(although a patient can be seen at any time for safety reasons). 
Note: 
• An optional visit approximately 1 week later MAY be completed if patient fails TG 
entry criterion.  If this optional visit is completed, the repeat lipid values will be used 
to determine eligibility. 
• An optional visit between Visits S1 and S2 may be scheduled to collect screening 
fasting labs in the event that the patient arrives at Visit S1 in a nonfasted state. 
• An optional visit between Visits S1 and S2 may be completed if the patient’s DBP 
and/or SBP meet the exclusion criteria levels.  Patients may randomize after BP 
medications have been adjusted, they have been on stable doses of BP medications 
for at least 2 weeks, and the repeat BP values (DBP and/or SBP) no longer meet 
exclusionary values. 
• An optional visit between Visits S1 and S2 may be completed to determine eligibility 
if the patient’s eGFR, ALT, AST, and/or TB meet exclusion criteria levels.  If this 
optional visit is completed, the repeated value will be used to determine eligibility. 
• Patients who are considered to be screen failures due to not meeting stability 
requirements for a condition or concurrent medication may be considered for 
rescreening after consultation with the Sponsor (or designee).  These patients must be 
re-consented, re-registered in the IWRS, and will have a new patient ID number 
assigned. 
10.2.2. 
Placebo Run-in Week -4 (Visit S2; Day -28± 3 days) 
Prior to scheduling Visit S2, review the screening clinical results to evaluate whether the patient 
continues to meet eligibility criteria.

whether the patient continues to meet eligibility criteria. 
• If the patient meets eligibility criteria, then schedule the Visit T1 and proceed with 
the Visit T1 procedures 
If the patient has met all inclusion criteria and none of the exclusion criteria, the patient may be 
randomized into the double-blind treatment period.  Patients who fail to meet any entry criterion 
prior to randomization are considered to be screen failures, will not be randomized into a 
treatment group, and are not required to return for additional visits.  Patients are considered 
randomized once all eligibility criteria are confirmed and a randomization number is obtained by 
the IWRS on the day of first dose.

Patients who do not provide consent to continue to return to the clinic for safety assessments 
after withdrawing from IMP treatment will be asked to participate in phone calls from the site at 
protocol-specified visits, or at a minimum at 52 weeks, to inquire about the patient’s current 
health status and collect information on AEs (eg, recent procedures, hospitalizations, and if the 
patient has died, the cause of death).  If the patient consents for telephone contacts, schedule the 
next protocol-specified visit. 
Patients will undergo the following assessments and procedures at Week 24 (Visit T5): 
• Concomitant and prohibited medication review (ongoing) 
• Assess AEs, SAEs, and potential clinical endpoints since last visit (ongoing)

Subject Withdrawal Criteria 
10.3.1. 
Early Withdrawal from the Study 
Patients must remain in the study until the last scheduled visit at Week 52 (Visit T7) to be 
considered as having completed participation in the study.  
Patients who withdraw from IMP prior to Week 52 (Visit T7) for any reason will be asked to 
continue to be followed for safety assessments, including basic fasting lipids, at clinic visit 
following the protocol-specified visit schedule (see Appendix 1). 
Patients who temporarily withdraw from IMP prior to Week 52 (Visit T7) for any reason may 
restart IMP providing that 1) the patient and the investigator are in agreement regarding this 
course of action, 2) the patient has been off of IMP for 4 weeks or less; and 3) IMP can be started 
as soon as possible. For cases where the patient has been off of IMP for more than 4 weeks, the 
investigator must contact the medical monitor for approval prior to restarting IMP. 
Patients who refuse to continue to return to the clinic for safety assessments will be asked to 
participate in phone calls from the site at protocol-specified visits (see Appendix 1), or at a 
minimum at 52 weeks, to collect information on AEs, concomitant medications, and current 
health status.  The patient must provide consent to be contacted by phone by site personnel for 
the purposes of assessing current AEs and current health status. 
The patient’s decision to participate in the clinical study is voluntary.  Patients may refuse to 
continue in the study and/or withdraw from participation in this study at any time, for any reason, 
specified or unspecified, and without penalty or loss of benefits to which the patient is otherwise 
entitled.  
It is the right and duty of the Investigator to interrupt the treatment of any patient whose health or 
well-being may be threatened by continuation in this study.  Such patients should be withdrawn 
from the study and should not be continued under a modified regimen. 
Patients who are withdrawn from the study may not re-enter.  The reasons for withdrawal from 
this study may include: 
• Patient’s withdrawal of consent 
• Failure to comply with the protocol 
• Lost to follow-up 
• Illness, condition, or procedural complication (including AEs) affecting the patient’s 
ability to participate or requiring prohibited medication 
• The Sponsor or Investigator terminates the study

Page 57 of 184 
• In the Investigator’s judgment, it is deemed in the best interest of the patient to 
discontinue his/her participation in the study 
• Any other reason 
If a patient is lost to follow-up, every reasonable effort must be made by the clinical site 
personnel to contact the patient and determine the reason for discontinuation/withdrawal.  The 
measures taken to follow-up must be documented. 
10.3.2. 
Procedures for Early Withdrawal 
If a patient withdraws or is removed from the study for any reason, all End of Study procedures 
should be completed.  Reason for withdrawal, date of the discontinuation, and date of the last 
dose of study drug should be recorded in the appropriate section of the eCRF.  Additionally, the 
discontinuation visit date must be registered in IWRS.  Study drug assigned to the withdrawn 
patient may not be assigned to another patient. 
All effort should be made to have each patient complete all study visits on schedule according to 
the protocol.  Accommodations for early or late visits in special circumstances will be considered 
by the Sponsor to prevent early withdrawal.  Written notice (regardless of cause) is to be 
provided within 48 hours of the withdrawal to the Sponsor personnel or the Medical Monitor.  At 
the time of discontinuation, every effort should be made to ensure all relevant procedures and 
evaluations scheduled for the final study visit are performed.  Except in the case of a medical 
emergency, the procedures and assessments detailed in Section 10.2.10 will be performed upon 
the discontinuation of the study. 
Patients choosing to withdraw from the study early should be encouraged to return for all study 
scheduled clinic visit even if they are no longer taking IMP.  Patients who withdraw from all 
aspects of the study will be asked to consent to clinical visits or phone calls for safety 
assessments, including AEs, concomitant medication, and current health status through Week 52 
(Visit T7).

ASSESSMENT OF SAFETY 
11.1. 
Safety Parameters 
At all clinic visits, investigators will review all safety information including vital signs, AEs, 
concomitant medications, and ECG reports and will ensure that the collected data are recorded 
into the appropriate eCRF.  Additionally, clinical laboratory samples will be collected and sent 
for analysis and the investigator will review the results to ensure continued patient safety while 
participating in the study.  
11.1.1. 
Demographic/Medical History 
Demographic data and a complete medical history will be obtained from the patient.  For medical 
history, conditions that are relevant and/or clinically significant should be captured with at least a 
start date (month and year) and whether the condition is ongoing or resolved.  All surgeries 
regardless of date should be reported.  
11.1.2. 
Vital Signs 
Vital signs will include DBP and SBP as well as heart rate. 
The patient should sit quietly for 5 minutes prior to collection of vital signs.  At all time points, 
vitals will be collected prior to blood collection.  Blood pressure and heart rate will be measured 
using a calibrated, fully automated machine with a cuff that is appropriate to the size of the upper 
arm.  If a fully automated machine is not available, BP may be measured manually.  The same 
method (either automated or manual) and the same arm (right or left) must be used throughout 
the study.  The patient should be in a seated position with feet touching the floor.  Patients should 
be seated quietly for at least 5 minutes in a chair with their backs supported, their feet flat on the 
ground, and their arms bared and supported at heart level. 
11.1.3. 
Weight, Height, and Body Mass Index 
Weight will be measured on a calibrated scale while fasted and after voiding. Body weight will 
be measured while fasting, using consistent scales, after voiding, and without shoes and 
outerwear (eg, coats).  
Height will be measured using standard clinic procedures.  
BMI will be calculated using the formula:  
BMI (kg/m2) = weight in kg / (height in meters)2

11.1.4. 
Physical Examination 
PEs will include an assessment of the following: 
• General appearance 
• Skin 
• Eyes, ears, nose, and throat 
• Head and neck 
• Extremities 
• Musculoskeletal examination 
• Respiratory examination 
• Cardiovascular assessment, including rhythm and presence of cardiac abnormalities 
• Abdominal examination 
• Neurologic examination including documentation of the presence of abnormalities in 
mental status and motor and sensory function 
• Any additional assessments necessary to establish baseline status or evaluate 
symptoms or adverse experiences 
Documentation of the PE findings will be included in the source documentation at the clinical 
site.  Significant findings prior to the start of study drug will be recorded on the Medical 
History/Current Medical Conditions page of the eCRF.  Only changes from baseline physical 
examination findings that meet the definition of an AE will be recorded on the AE page of the 
eCRF. 
Note:  Additional information will be collected regarding muscle-related AEs.  See 
Section 11.2.3. 
11.1.5. 
Electrocardiogram 
ECG collection will be preceded by a 10-minute rest time during which the patient will remain in 
the supine position.  At each time point, ECGs will be collected prior to blood collection.  ECGs 
will be assessed using machine readings and physician review. 
11.1.5.1. Monitoring and Management of Abnormal Electrocardiograms 
If a clinically significant ECG abnormality not present at baseline (screening) is determined by 
the Investigator to be related to study drug, the abnormality will be discussed with the Sponsor 
personnel or the authorized Medical Monitor, and followed and evaluated with additional tests (if 
necessary) until the underlying cause is determined or the event is brought to an acceptable 
resolution.  Additional clinical and laboratory information will be collected and carefully 
documented in order to better characterize the ECG abnormality and rule out alternative causes. 
ECG findings determined to be a clinically significant change from baseline should be reported 
as an AE regardless of causality. 
Unscheduled ECG assessments will be completed at the discretion of the Investigator.

shipped according to a separate laboratory manual provided by the Central Laboratory.  For 
collection and processing of PK samples, please see Section 11.1.6.5 and Section 11.1.6.6.  
Samples will be processed by the Central Laboratory.  
Blood draws for lipids, TG, and glucose must meet the criteria listed below.  If these criteria 
have not been met, these blood samples will NOT be collected.  If these criteria can be met by 
rescheduling the clinic visit to occur within 3 days, the lipid, TG, and/or glucose blood samples 
will be collected at the rescheduled clinic visit only.  
• Blood samples will be drawn after a minimum 10-hour fast (water is allowed) 
11.1.6.3. General Monitoring and Management of Abnormal Clinical Labs 
It is the Investigator’s responsibility to review the results of all laboratory tests as they become 
available and to sign and date the report to document their review.  For each laboratory test 
outside of the laboratory normal range, the Investigator needs to ascertain if this is a clinically

significant change from baseline for the individual patient, with baseline defined as the last value 
or observation before the first dose of study drug.  The Investigator may repeat the laboratory 
test or request additional tests to verify the results of the original laboratory test. 
If a laboratory value is determined to be an abnormal and clinically significant change from 
baseline for the patient, the Investigator should determine if it qualifies as an AE, and if yes, an 
appropriate eCRF will be completed.   
An abnormal laboratory value that is not already associated with an AE is to be recorded as an 
AE only if any one of the following criteria is met: 
• an action on the study drug is made as a result of the abnormality 
• intervention for management of the abnormality is required 
• at the discretion of the investigator should the abnormality be deemed clinically 
significant 
All clinically significant laboratory abnormalities occurring during the study that were not 
present at baseline should be followed and evaluated with additional tests if necessary, until 
diagnosis of the underlying cause or resolution.  Specific monitoring and management guidelines 
for laboratories of special interest are outlined in the sections below. 
11.1.6.3.1. Monitoring and Management of Elevated Liver Function Tests 
If at any time after randomization a patient experiences a new ALT and/or AST >3 × ULN, the 
patient will undergo repeat confirmatory liver function test (LFT) assessment as soon as is 
reasonably possible, preferably within 3 to 7 days of the laboratory result becoming available.  
Repeat LFT assessment will include:  1) measurement of ALT, AST, alkaline phosphatase, total 
and direct bilirubin, prothrombin time (PT)/international normalized ratio (INR), eosinophil 
count, CK, antihepatitis A virus (total), HBsAg (confirmation of screening measurement), HCV 
(confirmation of screening measurement), and anti-cytomegalovirus/immunoglobulin M; 
2) history of concomitant medication use; 3) history of exposure to environmental chemical 
agents, including ethanol; and 4) query for related symptoms.  Additionally, further testing such 
as liver ultrasound or magnetic resonance imaging (MRI) scanning may be warranted to rule out 
additional pathology depending on clinical presentation and should be discussed with the 
Sponsor personnel or the authorized Medical Monitor.  
• If repeat LFT assessment confirms ALT and/or AST >3 × ULN, consideration should 
be given to withdrawing the patient and administering no further doses of study drug.  
At the investigator’s discretion, study drug may be interrupted and the patient 
rechallenged with study drug after LFTs have returned to baseline levels.  
• If repeat LFT assessment confirms ALT and/or AST >5 × ULN, patient should be 
withdrawn from IMP treatment, but will be asked to continue to be followed for 
safety using the protocol-specified visit schedule (see Appendix 1) or more frequently 
if deemed by the investigator. 
• If repeat LFT assessment confirms ALT and/or AST >3 × ULN in addition to any of 
the following, the patient should be given no further IMP treatment, but will be asked

to continue to be followed for safety using the protocol-specified visit schedule (see 
Appendix 1) or more frequently if deemed by the investigator: 
− TB >2 × ULN 
Note:  In the case of patients with Gilbert’s disease, TB will be fractionated and 
the determination of 2 × ULN will be based upon direct (conjugated) bilirubin. 
− INR >1.5 × ULN (unless the patient is on stable dose of anticoagulation 
medication) 
− Appearance or worsening of right upper abdominal discomfort, anorexia, fatigue, 
nausea, vomiting, fever, rash, or eosinophilia 
11.1.6.3.2. Monitoring and Management of Elevated Serum Creatinine 
If at any time after randomization, a patient experiences a decrease in eGFR to the level of 
15 mL/min/1.73 m2) or if the patient experiences acute renal failure, the patient should be 
withdrawn from IMP treatment but will be asked to continue to be followed for safety using the 
protocol-specified visit schedule (see Appendix 1) 
11.1.6.3.3. Monitoring and Management of Hemoglobin Change 
If at any time after randomization a patient experiences a decrease >2.0 g/dL (20 g/L) from 
baseline (Week 0 [Visit T1]), the patient will undergo repeat confirmatory hematology testing as 
soon as is reasonably possible, preferably within 3 to 7 days of the laboratory result becoming 
available.  
Repeat hematology assessment will include: 1) measurement of Hgb, hematocrit (Hct), mean 
corpuscular hemoglobin, mean corpuscular hemoglobin concentration, mean corpuscular 
volume, platelet count, reticulocyte count (percent and absolute), red blood cell count (RBC), 
and white blood cell count (WBC) with differential (absolute values only); 2) history of 
concomitant medication use; and 3) query for related symptoms.  Additionally, further testing 
may be warranted to rule out additional pathology depending on clinical presentation, and should 
be discussed with Esperion Therapeutics personnel or the authorized Medical Monitor.  
• If repeat Hgb assessment confirms a decrease >2.0 g/dL (20 g/L) from baseline, the 
patient should be monitored carefully during the study and return at 2-week intervals 
after study completion for additional Hgb measurement until the level returns to 
baseline or reaches a stable level.  
• If repeat Hgb assessment confirms Hgb <8 g/dL (80 g/L), the patient should be 
withdrawn from IMP treatment. The patient will return at 1-week intervals after 
withdrawing from IMP treatment for additional Hgb measurement until the level 
returns to baseline or reaches a satisfactory conclusion. 
• If the patient is withdrawn from IMP treatment, the patient should be asked to 
continue being followed for safety using the protocol-specified visit schedule (see 
Appendix 1). 
At any time, the investigator may choose to consult with a specialist to further evaluate the cause 
of the alteration in Hgb.

11.1.6.3.4. Monitoring and Management of Elevated Creatine Kinase 
If at any time after randomization a patient experiences a marked CK elevation >5 × ULN, the 
patient will undergo repeat confirmatory assessment as soon as is reasonably possible, preferably 
within 3 to 7 days of the laboratory result becoming available.  
Repeat CK assessment will include query for related symptoms.  
• If the repeat CK assessment confirms an unexplained (ie, not associated with recent 
trauma or physically strenuous activity) CK abnormality >5 × ULN, if asymptomatic 
the patient should receive further assessment and investigation into the cause, assess 
whether there is renal injury and measure CK approximately weekly or more 
frequently if clinically indicated until resolution.  If CK levels continue to rise; IMP 
should be discontinued.   
• If symptomatic, the following should be completed: 
− Hold IMP 
− Clarification of the nature, duration, and intensity of muscle symptoms 
− Review possible predisposing factors, such as unaccustomed exercise, heavy 
alcohol intake, viral illness (consider performing serology)  
− Evaluation for additional diagnoses or other conditions which can cause 
myopathy including muscle tenderness (by PE), weakness, rash, measurement of 
serum creatinine, dipstick urinalysis with microscopy if indicated 
− Obtain clinical chemistries to assess the possibility of lactic acidosis 
− Follow symptoms and CK until the abnormality has resolved 
− If based on the above evaluation an alternative explanation is suspected, 
consideration can be given to resuming IMP once CK returns to baseline levels 
− If no alternative explanation exists, consideration should be given to withdrawing 
the patient from IMP treatment.  
• If the repeat CK assessment confirms an unexplained (ie, not associated with recent 
trauma or physically strenuous activity) CK abnormality as listed below, the patient 
should be withdrawn and given no further doses of study drug:  
− >10 × ULN, even in the absence of symptoms.  
− In all cases, evaluate the signs/symptoms and laboratory evaluations as outlined 
above. 
• If the patient is withdrawn from IMP treatment, the patient should be asked to 
continue being followed for safety using the protocol-specified visit schedule (see 
Appendix 1).

11.1.6.4. Monitoring and Management of Potential Hypoglycemia and Metabolic Acidosis 
Patients will be educated on the signs and symptoms of hypoglycemia.  If such signs and 
symptoms are experienced, patients will be instructed to report these signs and symptoms to the 
investigator.  
During each study visit, patients will be reminded to report all signs and symptoms associated 
with hypoglycemia to the investigator.  For each occurrence of patient-reported signs and 
symptoms associated with hypoglycemia, the investigator will discuss these symptoms with the 
patient and assess whether they are attributable to hypoglycemia or to another potential cause.  
All investigator-confirmed occurrences of hypoglycemia will be recorded as an AE.  All 
occurrences of signs and symptoms that are not confirmed by the investigator to be attributable 
to hypoglycemia will be reported using the appropriate diagnosis. 
Clinical laboratories will be assessed to determine any signs of anion gap metabolic acidosis.  If 
laboratories are consistent with metabolic acidosis, immediate follow up with the patient for 
further medical evaluation of the acidosis will occur.  This event should be captured as an AE.  
11.1.6.4.1. Monitoring and Management of Elevated LDL-C  
An adjunctive therapy plan is in place for those patients whose LDL-C values meet the protocol-
defined LDL-C threshold criteria. Post-randomization, LDL-C results will be masked to 
investigators in order to maintain the blind; however, the following thresholds have been set to 
notify investigators and provide an opportunity to adjust the patient’s standard of care regimen.  
• Beginning at Week 24 (Visit T5) visit and for the duration of the study, the central 
laboratory will notify the investigator when the patient’s LDL-C value is >170 mg/dL 
(4.4 mmol/L) and ≥25% from the patient’s baseline value at Week 0, (Visit T1)  
• Upon receiving notification from the central laboratory that the patient has met or 
exceeded the threshold criteria for LDL-C, the investigator will initiate the following 
adjunctive therapy plan: 
− Patients will be scheduled to return to the clinic within 1 week for a repeat fasting 
blood lipid sample to confirm that the LDL-C value meets the threshold criteria  
− After confirming that the LDL-C value meets or exceeds the threshold criteria, the 
investigator will adjust the patient’s lipid-lowering treatment regimen per 
standard-of-care and local practice, with the exception of simvastatin at doses 
≥40 mg/day and the fibrate, gemfibrozil. The patient’s LDL-C will be re-
evaluated at the next scheduled clinic visit as defined in the Schedule of Visits 
(Appendix 1). 
− The initiation of any new or dose changes of any existing lipid-lowering treatment 
will be documented on the eCRF as a concomitant medication with the associated 
start date 
− Patients who have their lipid-lowering medications modified, including new 
medications or dosage changes to existing medications, should return to the clinic 
in 4 weeks after the modification to their lipid-lowering treatment for a routine

safety laboratory assessment.  Additional safety laboratory assessments may be 
conducted at the investigator’s discretion. 
− Adjunctive therapy medications will not be provided by the sponsor 
− Patients continuing to exceed the LDL-C threshold after maximizing the standard-
of-care LCL-C-lowering therapy and, in the opinion of the investigator, require 
therapies that are prohibited by the protocol will be discontinued from IMP 
treatment and will be asked to continue to be followed for safety using the 
protocol-specified visit schedule (see Appendix 1). 
− Please see the Clinical Laboratory Manual and Section 11.7 for sample collection 
and instructions. 
11.1.6.4.2. Monitoring and Management of Elevated Triglycerides 
Patients may continue to use stable doses of TG-lowering medications during the study.  An 
adjunctive therapy plan is in place for those patients whose TG values meet the protocol-defined 
threshold criteria.  Post-randomization, TG results will be masked to investigators in order to 
maintain the blind; however, a threshold has been set to notify investigators and provide an 
opportunity to adjust the patient’s standard of care regimen.  Beginning at Week 4 (Visit T2), if 
the TG level exceeds 1000 mg/dL (11.3 mmol/L) while on treatment, the investigator will 
receive notification from the central laboratory that the patient has met or exceeded the protocol-
defined threshold criteria for TG.  The investigator will initiate the following plan: 
• Any patient with TG >1000 mg/dL (11.3 mmol/L), will be reminded to fast for at 
least 10 hours and will return to clinic within 1 week for a repeat, fasting TG sample 
to confirm the TG value meets the threshold criteria  
• Any patient with a confirmed TG >1000 mg/dL (11.3 mmol/L) may initiate standard-
of-care therapy (however, gemfibrozil may not be added) to lower TG using a patient-
specific prescription.  The initiation of this medication will be documented on the 
case report form as a concomitant medication with the associated start date.  These 
medications will not be provided by the sponsor. 
• Patients continuing to exceed the TG threshold after maximizing the standard-of-care 
triglyceride-lowering therapy will be discontinued from IMP treatment and will be 
asked to continue to be followed for safety using the protocol-specified visit schedule 
(see Appendix 1). 
• Please see the Clinical Laboratory Manual and Section 11.7 for sample collection and 
instructions. 
11.1.6.5. Pharmacokinetic Assessments 
Pharmacokinetic assessments to measure plasma concentrations of bempedoic acid and its 
metabolite ESP15228 will be conducted from 6 mL whole blood samples collected.  At the time 
of sample collection, the date and time of blood draw and the last 2 doses of study medication 
will be collected.  Pharmacokinetic sample analyses for bempedoic acid and ESP15228 will be 
conducted by the Bioanalytical Laboratory.

11.1.6.6. Collection and Assessment of Pharmacokinetic Samples 
Pharmacokinetic samples will be collected from patients at Weeks 24 and 52, for use in further 
developing the population PK model.  
Plasma concentrations of bempedoic acid and its metabolite (ESP15228) will be determined 
using validated methods.  Plasma PK samples will be labeled with preprinted information, 
including study number, patient identification number, study day, nominal time of sample 
collection, matrix, and a text identification (ie, “Plasma PK”).  See the study laboratory manual 
for further instructions. 
11.1.6.7. Shipment of Pharmacokinetic Samples 
Plasma PK samples will be shipped frozen on dry ice according to instructions provided in the 
laboratory manual. 
11.1.6.8. Total Blood Volume of Clinical Laboratory and Pharmacokinetic Samples 
The total number of venipunctures and total volume of whole blood collected during the study 
will be limited to that needed for safety monitoring, PK, efficacy, and biomarker assessment.  
Total whole blood volume collected over the study duration is not to exceed approximately 
250 mL for each patient. 
11.2. 
Adverse and Serious Adverse Events 
11.2.1. 
Definition of Adverse Events 
An AE is any untoward medical occurrence in a clinical investigation patient administered a 
pharmaceutical product, including control, and which does not necessarily have a causal 
relationship with treatment.  
An AE can be: 
• Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of a medicinal product, 
whether or not considered related to the medicinal product 
• Any new disease or exacerbation of an existing disease 
• Any deterioration in nonprotocol-required measurements of laboratory value or other 
clinical test (eg, ECG or x-ray) that results in symptoms, a change in treatment, or 
discontinuation from study drug 
• TEAEs are defined as AEs that begin or worsen after the first dose of study drug 
• Adverse drug reaction (ADR; see Section 11.2.2) 
11.2.2. 
Adverse Drug Reaction 
All noxious and unintended responses to a medicinal product related to any dose should be 
considered an ADR.  “Responses” to a medicinal product means that a causal relationship

Clinical Study Protocol 1002-047 
 
Amendment 3, 09 May 2017 
Confidential 
Page 68 of 184 
between a medicinal product and an AE is at least a reasonable possibility (ie, the relationship 
cannot be ruled out). 
An unexpected ADR is defined as an adverse reaction, the nature or severity of which is not 
consistent with the applicable product information (eg, IB for an unapproved investigational 
product or package insert/summary of product characteristics for an approved product). 
11.2.3. 
Reporting  
All AEs occurring during the course of the study (starting from signing informed consent to 
study completion or discontinuation) will be collected on the AE eCRF.  Patients should be 
instructed to report any AE that they experience to the Investigator through 30 days following 
the last dose of study drug.  Beginning with Visit S1 (Week -5), Investigators should make an 
assessment for AEs at each visit and record the event on the appropriate AE eCRF.  Any SAE 
that occurs from the time of ICF through 30 days following the last dose of study drug should be 
reported to the Sponsor per Section 11.3. 
Wherever possible, a specific disease or syndrome rather than individual associated signs and 
symptoms should be identified by the Investigator and recorded on the eCRF.  However, if an 
observed or reported sign or symptom is not considered a component of a specific disease or 
syndrome by the Investigator, it should be recorded as a separate AE on the eCRF.  Additionally, 
the condition that led to a medical or surgical procedure (eg, surgery, endoscopy, tooth 
extraction, transfusion) should be recorded as an AE, not the procedure.  
Any medical condition already present at screening or baseline should not be reported as an AE 
unless the medical condition or signs or symptoms present at baseline changes in severity or 
seriousness at any time during the study.  In this case, it should be reported as an AE. 
Clinically significant abnormal laboratory or other examination (eg, ECG) findings that are 
detected during the study or are present at baseline and significantly worsen during the study 
should be reported as AEs.  The Investigator will exercise his or her medical and scientific 
judgment in deciding whether an abnormal laboratory finding or other abnormal assessment is 
clinically significant.  Significant abnormal laboratory values occurring during the clinical study 
will be followed until repeat tests return to normal, stabilize, or are no longer clinically 
significant.  Any abnormal test that is determined to be an error does not require reporting as an 
AE. 
Each AE is to be evaluated for duration, severity, seriousness, and causal relationship to the 
investigational drug. For each AE, the following information will be recorded: 
• Description of the event (eg, headache) 
• Date of onset 
• Date of resolution (or that the event is continuing) 
• Action taken as a result of the event 
• Seriousness of the event 
• Severity of the event 
• Outcome of the event

Amendment 3, 09 May 2017 
Confidential 
Page 69 of 184 
• Investigator’s assessment of relationship to study drug. 
A cluster of signs and symptoms that results from a single cause should be reported as a single 
AE (eg, fever, elevated WBC, cough, abnormal chest x-ray, etc, can all be reported as 
“pneumonia”). 
The Investigator will carefully evaluate the comments of the patient and the response to 
treatment in order that he/she may judge the true nature and severity of the AE.  The question of 
the relationship of AEs to study drug administration should be determined by the Investigator or 
study physician after thorough consideration of all facts that are available. 
Additional information will be collected regarding muscle-related AEs that may include, but may 
not necessarily be limited to, a muscle-related questionnaire, with questions regarding type of 
muscle-related symptoms, location of the muscle-related AE, and potential cause of the muscle-
related AE.  
11.2.4. 
Severity 
It is the Investigator’s responsibility to assess the intensity (severity) of an AE.  
The severity of the AE will be characterized as mild, moderate, or severe according to the 
following definitions: 
• Mild:  Events are usually transient and do not interfere with the patient’s daily 
activities 
• Moderate:  Events introduce a low level of inconvenience or concern to the patient 
and may interfere with daily activities  
• Severe:  Events interrupt the patient’s usual daily activity, are incapacitating with 
inability to do usual activities, or significantly affect clinical status and warrant 
intervention and/or close follow-up 
Note:  A severe AE need not be serious and an SAE need not, by definition, be severe. 
11.2.5. 
Relationship 
It is the Investigator’s responsibility to assess the relationship between the study drug and the 
AE.  The degree of “relatedness” of the AE to the study drug may be described using the 
following scale: 
• Not Related:  No temporal association and other etiologies are likely the cause 
• Unlikely:  While cannot be definitively ruled as not related to IMP, a causal 
association is remote, and other etiologies are more likely to be the cause.  For 
reporting and summarization, events assessed as “Unlikely” to be related to IMP will 
be considered as “Not Related” to IMP for regulatory reporting purposes.  
• Possible: Temporal association, but other etiologies are likely the cause.  However, 
involvement of the study drug cannot be excluded. 
• Probable:  Temporal association, other etiologies are possible but unlikely.  The event 
may respond if the study drug is discontinued.

Page 70 of 184 
• Definite:  Established temporal association with administration of the study drug with 
no other more probable cause.  Typically, the event should resolve when the study 
drug is discontinued and recur on re-challenge. 
11.2.6. 
Monitoring and Follow-up of Adverse Events 
Patients having AEs will be monitored with relevant clinical assessments and laboratory tests, as 
determined by the Investigator.  All follow-up results are to be reported to the Sponsor personnel 
or the authorized Medical Monitor.  Any actions taken and follow up results must be recorded 
either on the appropriate page of the eCRF or in appropriate follow-up written correspondence, 
as well as in the patient’s source documentation.  Follow-up laboratory results should be filed 
with the patient’s source documentation. 
For all AEs that require the patient to be discontinued from the study, relevant clinical 
assessments and laboratory tests must be repeated at appropriate intervals until final resolution, 
stabilization of the event(s), or until the patient is lost to follow-up or dies. 
Patients with AEs that are ongoing at study completion or study withdrawal must be followed 
until resolution or for 30 days after the last study visit, whichever comes first (see Section 11.3). 
11.2.7. 
Treatment-Emergent Adverse Events 
TEAE are defined as AEs that begin or worsen after the first dose of study drug. 
11.2.7.1. Definition of Serious Adverse Event  
An SAE is defined as any AE occurring at any dose that results in any of the following 
outcomes:  
• Results in death 
• Is life threatening 
• Requires in-patient hospitalization or prolongation of existing hospitalization 
• Results in persistent or significant disability/incapacity, or substantial disruption of the 
ability to conduct normal life functions 
• Is a congenital anomaly/birth defect 
• An important medical event 
NOTE:  Hospitalization is defined as a formal inpatient admission.  This will not include 
admissions under “23-hour Observational Status”, an Emergency Room visit without hospital 
admission or an Urgent Care visit and therefore, such events will not be recorded as an SAE 
under this criterion.  Admission to the hospital for social or situational reasons (eg, no place to 
stay, live too far away to come for hospital visits) will not be considered inpatient 
hospitalizations.  
Important medical events that may not result in death, be life threatening, or require 
hospitalization may be considered an SAE when, based upon appropriate medical judgment, they 
may jeopardize the patient and may require medical or surgical intervention to prevent one of the 
outcomes listed in this definition.  Examples of such medical events include allergic

Page 71 of 184 
bronchospasm requiring intensive treatment in an emergency room, blood dyscrasias, 
convulsions that do not result in inpatient hospitalization, or the development of drug 
dependency or drug abuse. 
Any clinical endpoints that meet SAE criteria will be reported as SAEs.  The CEC will 
adjudicate clinical endpoints in a blinded fashion, but the DMC will review clinical endpoints 
and SAEs in an unblinded fashion. 
11.2.7.2. Events not Qualifying as Serious Adverse Events 
The following is not considered an SAE and therefore does not need to be reported as such: 
• Overdose of either Esperion study drug or concomitant medication unless the event 
meets SAE criteria (eg, hospitalization).  However, the event should still be captured 
as a nonserious AE on the appropriate eCRF page 
11.2.7.3. Clinical Laboratory Assessments as Adverse Events and Serious Adverse Events 
It is the responsibility of the investigator to assess the clinical significance of all abnormal values 
as defined by the list of reference ranges from the central (or local where appropriate) laboratory.  
In some cases, significant changes in lab values within the normal range will require similar 
judgment.  For criteria of reporting abnormal lab values as AE, see Section 11.1.6.3. 
11.3. 
Reporting Serious Adverse Events 
All SAEs, regardless of relationship to study drug, occurring from the time of informed consent 
until 30 days following the last dose of IMP, must be reported by the Principal Investigator or 
designee to the authorized Medical and Safety Services within 24 hours of the Principal 
Investigator or the clinical site becoming aware of the occurrence.  For most patients this will be 
30 days following their Week 52 (Visit T7) visit. All SAEs that the Investigator considers related 
to study drug that occur after the 30-day follow-up of the study period must be reported to the 
Sponsor.  
To report the SAE, complete the SAE information in the clinical electronic data capture (EDC) 
database within 24 hours of becoming aware of the occurrence.  Additional information, such as 
diagnostic test results or hospital discharge summary can be sent via email 
 or via fax (
).  
The Investigator is required to submit SAE reports to the IRB/IEC in accordance with local 
requirements.  All Investigators involved in studies using the same investigational product will 
receive any safety alert notifications for onward submission to their local IRB as required.  All 
reports sent to Investigators will be blinded. 
All SAEs should be recorded on the eCRF and source documents.  Criteria for documenting the 
relationship to study drug and severity will be the same as those previously described. 
The Investigator must continue to follow the patient until the SAE has subsided or until the 
condition becomes chronic in nature, stabilizes (in the case of persistent impairment), or the 
patient dies.

Within 24 hours of receipt of follow-up information, the Investigator must update the SAE form 
and submit any supporting documentation (eg, patient discharge summary or autopsy reports) to 
the safety contact information provided on the SAE report form.  
11.3.1. 
Reporting of Serious Adverse Events to Regulatory Authorities 
The Sponsor (and/or designee) is responsible for submitting expedited reports of suspected and 
unexpected serious adverse reactions (SUSARS) to the appropriate regulatory authorities.  All 
Investigators participating in ongoing clinical studies with the study drug will be notified by the 
Sponsor (or designee) of SUSARs.  SUSARS must be communicated as soon as possible to the 
appropriate IRB/IEC by the investigator, as applicable and/or reported in accordance with local 
laws and regulations.  Investigators should provide written documentation of IRB/IEC 
notification for each report to the Sponsor. 
SAEs that are anticipated to occur in this patient population will be collected and reported by the 
Investigator as described in Section 11.3.  However, these events will not be submitted to the 
regulatory authorities as expedited reports unless they meet SUSAR criteria.  These events that 
are considered to be exempt from expedited reporting include the following clinical endpoints: 
• CV death 
• Nonfatal MI 
• Nonfatal stroke 
• Unstable angina requiring hospitalization 
• Coronary revascularization 
• Heart failure requiring hospitalization 
• Noncoronary arterial revascularization 
11.3.2. 
Reporting of Patient Death 
The death of any patient during the study, or within the 30-day follow-up period after they have 
completed the study (regardless of the cause), must be reported as detailed in Section 11.3. 
11.3.3. 
Reports of Pregnancy 
If a female patient becomes pregnant during the study or within 30 days after the last dose of 
study drug, the investigator is to stop dosing with study drug(s) immediately.  A pregnancy is not 
considered to be an AE or an SAE; however, it must be reported to the Sponsor / SAE designee 
using the paper Pregnancy Report Form within the same timelines as an SAE. A pregnancy 
should be followed through to outcome, whenever possible. Once the outcome of the pregnancy 
is known, the paper Pregnancy Outcome Report Form should be completed and reported to the 
Sponsor. Adverse events or SAEs that occur during pregnancy will be assessed and processed 
according to the AE or SAE processes using the appropriate AE CRF.  Patients who become 
pregnant will discontinue IMP immediately and complete the End of Study evaluations.

11.4. 
Adverse Events of Special Interest 
Adverse events of special interest (AESI) include metabolic acidosis (clinical laboratories), 
hepatic, muscular (AE and CK evaluation), new onset diabetes/hyperglycemia, renal, 
cardiovascular, and neurocognitive/neurologic events.  Based on previous experience with 
ETC-1002, uric acid and hemoglobin will be closely monitored.  Safety monitoring guidelines 
for hemoglobin is detailed in Section 11.1.6.3.3.  Specific monitoring guidelines are provided in 
the case of AEs uncovered through laboratory evaluations.  Patients are to be queried at each 
study visit regarding changes in cognition and or signs/symptoms of hypoglycemia. 
The protocol procedures included in the bempedoic acid clinical studies are part of standard 
clinical care for patients with primary hyperlipidemia and mixed dyslipidemia and also address 
the potential and theoretic risks of bempedoic acid.  
All bempedoic acid studies will include standard pharmacovigilance including evaluation of 
AEs, PE findings, vital signs, and laboratory assessments.  Cardiovascular events will be 
adjudicated by an independent CEC in accordance with a prespecified charter.  AESI monitoring 
will also include the following:  
• AEs associated with the experiences with bempedoic acid to date: 
Across clinical studies to date, the most frequently reported TEAEs included 
musculoskeletal and connective tissue disorders (back pain, pain in extremity, 
myalgia, arthralgia, and muscle spasms), nervous system disorders (headache), GI 
disorders (nausea and diarrhea), and infections and infestations.  Overall, AEs were 
generally reported with similar incidence between those patients treated with 
bempedoic acid in combination with ezetimibe or statin therapy, ezetimibe, statins, or 
placebo; however, the incidence of headache was higher with bempedoic acid than 
placebo. 
In general, laboratory results showed no clinically significant trends at the data cut-
off for End-of Phase 2.  A total of 7 patients receiving bempedoic acid monotherapy 
or in combination with a statin or ezetimibe experienced repeated and confirmed ALT 
and/or AST >3 × the ULN; in 1 of these patients receiving bempedoic acid 80 mg the 
elevation was assessed by Investigator as not related to study drug because the patient 
tested positive for acute cytomegalovirus (CMV) infection.  One patient receiving 
ezetimibe monotherapy experienced repeated and confirmed ALT and/or AST >3 × 
ULN.  All LFT abnormalities were considered mild to moderate and improved upon 
removal of the study drug.  Clinical chemistries, hematology, vitals, physical 
examinations, and ECGs will be routinely monitored in the bempedoic acid clinical 
program.  
• Potential AEs based on findings in nonclinical models: 
Hypoglycemia and metabolic acidosis led to monkey deaths in preclinical studies.  
Exposures in these studies were >17 times higher than those associated with the 
bempedoic acid 180-mg dose which will be evaluated in this study.  Subsequent 
monkey studies proved that hypoglycemia was reversible with discontinuation of 
study drug and nutritional support.  No cases of either hypoglycemia or metabolic 
acidosis have been identified in Phase 1 or 2 clinical trials to date.  Patients in all

clinical trials will be provided with information (in the ICF) regarding the signs and 
symptoms of hypoglycemia including lightheadedness, shakiness, shaking of the 
hands, sweating, tingling, blurred visions, nausea or vomiting, mental confusion, 
difficulty concentrating and drowsiness.  Patients who experience any of these 
symptoms will be instructed to report them to their study doctor.  Diabetes/glycemic 
monitoring plans are Section 11.1.6.4.  Occurrence of metabolic acidosis will be 
monitored by clinical safety laboratory chemistries. 
• AEs that are currently monitored for all experimental lipid-lowering therapies and 
have been associated with previous lipid-lowering therapies:  
Hepatic:  Hepatic function will be monitored throughout with the clinical safety labs. 
More detailed investigation will occur if the safety clinical laboratory results are 
3 times or more than the ULN (see Section 11.1.6.3.1).  
Muscle:  Muscle events have been associated with statins (Thompson 2003) and other 
lipid-lowering therapies and are mentioned in the product information for those 
products.  The exact mechanism in the development of muscle events is unclear.  
Bempedoic acid is a prodrug which needs to be converted by an acyl-CoA synthetase 
(ACS) to a coenzyme A (CoA) ester (ETC-1002-CoA).  The specific ACS known to 
convert bempedoic acid into its active form is not present in skeletal muscle.  This 
suggests that bempedoic acid may not lead to an increase in muscular side effects 
when given in conjunction with statins.  Nonetheless, muscle symptoms through AE 
review, CK elevations, and symptoms of potential myopathy will be closely 
monitored.  More detailed investigation will occur if results exceed 5 x ULN (see 
Section 11.1.6.3.2).  
Diabetes and Hyperglycemia:  New onset diabetes has been associated with the use of 
statins and is dose related.  The product information for statins mentions 
hyperglycemia increased HbA1C and increases in fasting glucose as potential adverse 
reactions.  Hyperglycemia occurred in 10.8% (n = 10) of the placebo treated patients 
vs none of the bempedoic acid 180 mg treated patients in the Phase 2 program.  
Regardless, new onset diabetes through AE monitoring will be captured and 
summarized for this study and across all of the bempedoic acid studies.  Clinical 
safety laboratories will also be evaluated during the studies including HbA1C, and 
fasting glucose.  
Renal:  Nonclinical studies have demonstrated nephrotoxic effects on tubular cells of 
some lipid-modifying agents.  In the Phase 2 program, creatinine elevations >25% 
over baseline occurred in 1 subject in the bempedoic acid 80 mg, 2 in the 180 mg, 
1 in the 180 mg + ezetimibe, 1 in the 240 mg, and 3 in the 240 mg + baseline statin.  
In most cases, this elevation occurred at the end of the study and the values were not 
repeated and the events were not considered related.  In 1 case, repeat values were 
obtained and the subject’s creatinine was returning to baseline by Week 12.  None 
exceeded a serum creatinine >1.8 mg/dL.  No subjects withdrew due an AE of 
increased creatinine.  In the Phase 3 program, repeat evaluation of creatinine will 
occur and patients exceeding protocol-specified values will be withdrawn from study 
medication (see Section 11.1.6.3.2).  Patients will be monitored beyond the

conclusion of the study if necessary to follow abnormal renal laboratory values until 
resolution or stabilization.  
Cardiovascular Events:  The occurrence of clinical endpoints will be monitored and 
adjudicated by an independent blinded CEC throughout the bempedoic acid program.  
The details of the monitoring program can be found in the charter of the CEC.  
Standard monitoring will include occurrence of CV AEs, SAEs, both as adjudicated 
by the CEC, standard vital signs, and ECGs.  
Neurocognitive Events:  Theoretically, it is possible that lipid-lowering agents that 
disrupt cholesterol homeostasis in the brain could impact neurological function, and 
there have been reports of cognitive impairment (eg, memory loss) associated with 
the use of statin drugs (FDA 2012).  The human brain has a significant requirement 
for cholesterol (Dietschy 2001; Dietschy 2004) and dysregulation of brain cholesterol 
homeostasis has been linked to chronic neurodegenerative disorders, including 
Alzheimer’s disease, Huntington’s disease, Parkinson’s disease, Niemann–Pick 
type C disease and Smith-Lemli-Opitz syndrome (Goedeke 2014).  In the Phase 2 
program, the only disorder in this system organ class (SOC) that occurred more 
commonly in the bempedoic acid treated group was headache. For the ongoing 
program, neurocognitive events will be evaluated by standard PE and adverse 
monitoring. Summarization of events will occur using prespecified Medical 
Dictionary for Regulatory Activities (MedDRA) terms. 
11.5. 
Data Monitoring Committee 
An independent DMC will monitor unblinded accumulating patient safety and efficacy data until 
the last patient has completed study treatment.  In addition, data on SAEs and deaths, including 
clinical endpoints, will be monitored by the DMC during this period.  At each DMC review, 
relevant unblinded safety and efficacy information from ongoing studies of bempedoic acid will 
be provided to the DMC by an independent unblinded statistician and programmer.  Additional 
details will be provided in a DMC Charter. 
11.6. 
Clinical Event Committee (CEC) 
A blinded independent expert CEC will adjudicate clinical endpoints including all MACE and 
non-MACE endpoints defined as:  CV death (MACE), non-CV death (non-MACE), nonfatal MI 
(MACE), nonfatal stroke (MACE), hospitalization for unstable angina (MACE), coronary 
revascularization (MACE), non-coronary arterial revascularization (non-MACE), and 
hospitalization for heart failure (non-MACE) using standardized definitions.  Any clinical 
endpoints that meet SAE criteria will be reported as SAEs.  Additional details regarding clinical 
endpoints and clinical endpoint definitions are outlined below and will be included in the CEC 
charter.  The charter will also outline the committee’s composition, meeting timelines, and 
members’ roles and responsibilities.  Clinical endpoints from this study and other studies within 
the bempedoic acid Phase 3 development program will be aggregated to allow for a safety 
assessment across the entire development program.

Assessment of Lipid Endpoints 
11.7.1. 
Lipid Parameters 
After randomization, patients will return to clinic every 4 weeks for the first 12 weeks, then 
again 12 weeks later at Week 24 (Visit T5) and at Week 52 (Visit T7).  Clinical laboratory 
samples will be collected and analyzed for calculated LDL-C and lipid and cardiometabolic 
biomarkers including non-HDL-C, HDL-C, TC, apoB, and TG at baseline and all clinic visits for 
evaluation of bempedoic acid effects on lipids and cardiometabolic parameters.  
11.7.2. 
Clinical Laboratory Tests (Lipids) 
Clinical laboratory samples will be collected at all clinic visits.  
Blood draws for lipids (and glucose) must meet the criteria below.  If these criteria have not been 
met, these blood samples will NOT be collected.  If these criteria can be met by rescheduling 
clinic visit to occur within 3 days, these blood samples will be collected at the rescheduled 
clinic visit only.  
• Blood samples will be drawn after a minimum 10-hour fast (water is allowed)  
Patients are encouraged to be in a seated position during the blood collection.  Clinical laboratory 
parameters and tests will include those listed in Table 6.  Collection schedule and instructions are 
provided in the Clinical Laboratory Manual.  A description of the sample collection, storage, and 
shipping as well as monitoring and management of abnormal laboratories are described in 
Section 11.1.6. 
When ECG, vital signs, and laboratory samples are to be collected at the same time point, ECG 
and vital sign measurements will precede laboratory sample collection.

STATISTICS 
12.1. 
General Considerations 
The statistical analyses described in this section will be performed as further outlined in a 
separate Statistical Analysis Plan (SAP).  The SAP will supersede the protocol in the event of 
any differences between the 2 documents in the plans for data analysis, and the protocol will be 
amended if appropriate.  The SAP will be included as an appendix in the clinical study report for 
this protocol. 
12.2. 
Determination of Sample Size 
The primary efficacy endpoint for this study is the percent change from baseline to Week 12 in 
LDL-C.   
The sample size of 500 randomized patients in the bempedoic acid 180 mg group and 
250 randomized patients in the placebo group is expected to provide more than 95% power to 
detect a difference of 15% in the percent change from baseline to Week 12 in LDL-C between 
the bempedoic acid treatment group and the placebo group.  This calculation is based on a 
2-sided t-test at the 5% level of significance (α = 0.05) and a common standard deviation of 15%.  
The sample size of 500 randomized patients in the bempedoic acid 180 mg group and 
250 randomized patients in the placebo group gives a total study sample size of 750.   
12.3. 
Analysis Populations  
The Full Analysis Set (FAS), used for all of the efficacy summaries and analyses, is defined as 
all randomized patients.  The FAS is also known as the intention-to-treat (ITT) set of patients.  
Patients in the FAS will be included in their randomized treatment group, regardless of their 
actual treatment.  
The Safety Population (SP), used for all of the safety summaries, is defined as all randomized 
patients who received at least 1 dose of study medication.  Patients in the SP will be included in 
the treatment group that they actually received, regardless of their randomized treatment.  
12.4. 
Disposition, Demographics, and Baseline Characteristics 
Disposition, including reason for withdrawal from the study, will be summarized by treatment 
group.  Demographic information and patient characteristics including, but not limited to, 
gender, race, age, and baseline vital signs will also be summarized by treatment group. 
12.5. 
Primary Endpoint 
The primary efficacy endpoint is the percent change from baseline to Week 12 in LDL-C.  The 
primary efficacy endpoint will be analyzed using analysis of covariance (ANCOVA), with 
treatment group, CV risk (ASCVD only; HeFH with or without ASCVD) and baseline statin 
intensity (high intensity, moderate intensity, low intensity) as factors and baseline LDL-C as a

covariate.  Baseline LDL-C is defined as the mean of the LDL-C values from Week -1 (Visit S3) 
and predose Day 1/Week 0 (Visit T1).  If a repeat lipid measurement is performed at Week -1 
(Visit S3), then baseline will be the mean of the LDL-C values from the second Week -1 
assessment and predose Day 1/Week 0 (Visit T1).  If only one value is available, then that single 
value will be used for baseline.  The ANCOVA will be performed using the FAS, with patients 
included in their randomized treatment group regardless of the treatment they actually received.  
The details of the ANCOVA model and options to correct for unequal variances and group size 
will be described in the SAP. 
Missing data for the primary endpoint will be imputed using a multiple imputation method that 
accounts for treatment adherence. A pattern mixture model (PMM) will be used to specify 
different imputation strategies depending on whether the patient is still on study treatment.  
Imputed datasets will be analyzed using ANCOVA with treatment group, CV risk (ASCVD 
only; HeFH with or without ASCVD) and baseline statin intensity (high intensity, moderate 
intensity, low intensity) as factors and baseline LDL-C as a covariate.  Approximately 
200 imputed datasets will be created, with results from the analysis of each imputed dataset 
combined using Rubin’s method.  The least squares mean (LSM) and standard error (SE) will be 
provided for both treatment groups, along with the placebo-corrected LSM, its 95% confidence 
interval (CI), and associated p-value.  A confirmatory analysis using observed data only will also 
be performed for the primary endpoint. Details for PMM and multiple imputation will be 
descried in the SAP. 
12.6. 
Secondary and Tertiary Efficacy Endpoints 
Key secondary efficacy endpoints are also of interest for this study, in terms of controlling the 
overall Type I error rate.  A gatekeeping or stepdown approach will be used to test the primary 
efficacy endpoint and then specific secondary efficacy endpoints sequentially in order to 
preserve the study-wise Type I error rate.  The sequence for the stepdown procedure in this study 
is as follows: 
1. Test the primary efficacy endpoint: percent change from baseline to Week 12 in LDL-C  
2. Test the percent change from baseline to Week 24 in LDL-C 
3. Test the percent change from baseline to Week 12 in non-HDL-C 
4. Test the percent change from baseline to Week 12 in TC 
5. Test the percent change from baseline to Week 12 in apoB 
6. Test the percent change from baseline to Week 12 in hs-CRP   
In this hierarchical testing structure, each hypothesis is tested at a significance level of 0.05, two-
sided.  Statistical significance at each step is required in order to test the next hypothesis.  If the 
primary endpoint meets the criteria for statistical significance, then the percent change from 
baseline to Week 24 in LDL-C will be tested; and so forth. 
In general, change or percent change in lipid parameters at a given time point will be analyzed 
using similar ANCOVA model for the primary endpoint with treatment group, CV risk (ASCVD 
only; HeFH with or without ASCVD) and baseline statin intensity (high intensity, moderate 
intensity, low intensity) as factors and the relevant baseline as a covariate.

Baseline for HDL-C, non-HDL-C, TG, and TC will be defined as the mean of the lipid values 
from Week -1 (Visit S3) and predose Day 1/Week 0 (Visit T1).  If a repeat lipid measurement is 
performed at Week -1 (Visit S3), then baseline will be the mean of the lipid values from the 
second Week -1 assessment and predose Day 1/Week 0 (Visit T1).  Baseline for apoB and 
hs-CRP will be defined as the predose Day 1/Week 0 (Visit T1) value.   
Each ANCOVA will be performed using the FAS, with patients included in their randomized 
treatment group regardless of the treatment they actually received.  Same imputation method 
described for the primary endpoint will be used for those secondary endpoints included in the 
step-down procedure, while only observed data analysis will be used for other secondary and 
tertiary endpoints.  For each lipid parameter and analysis time point, the LSM and SE will be 
provided for both treatment groups, along with the placebo-corrected LSM, its 95% CI and 
associated p-value. 
The ANCOVA assumption of normality will be assessed.  If non-normality of the data is found 
at any time point for any parameter, either the data will be transformed so that it is normally 
distributed or a nonparametric test will be considered instead of the planned ANCOVA. 
Percent change from baseline to Week 24 and to Week 52 LDL-C will be analyzed similarly 
with patients in the FAS who did not receive additional lipid-lowering therapy by that time point 
(by Week 24 for the Week 24 analysis; by Week 52 for the Week 52 analysis) included in the 
analyses. Only observed case data will be used (no imputation for missing data). Output from 
each time point will include the LSM and SE for each treatment group, as well as the placebo-
correct LSM, 95% CI, and p-value. 
12.7. 
Additional Post-randomization Adjunctive LDL-lowering or 
Triglyceride-Modifying Therapy 
The number and percent of patients in each treatment group requiring additional (post-
randomization) adjunctive LDL-C or triglyceride-modifying therapy will be summarized.  
Medications and the reasons for their additional treatment (hyperlipidemia vs. 
hypertriglyceridemia) will be summarized separately. 
12.8. 
Safety Endpoints 
The summarization of AEs will include TEAEs.  TEAEs and SAEs will be summarized by SOC, 
severity, and relationship to study drug for each treatment group.  These AE summaries will 
include cumulative incidence (percent of patients experiencing the AE) and patient-year adjusted 
incidence rates.  If appropriate, absolute and relative risk differences will be calculated using 
both cumulative incidence and incidence rates.  Deaths, withdrawal from study treatment due to 
AEs, and withdrawal from the study due to AEs will each be summarized by treatment group. 
Clinical safety laboratories, including hematology, blood chemistry, coagulation, HbA1C, 
glucose, and urinalysis; PE findings; vital signs; ECG readings; and weight will be summarized 
by the value and by change from baseline in the value (where appropriate) at each postbaseline 
time point.

Hepatic Safety 
Liver-associated enzymes and TB will be summarized by the value and change from baseline in 
the value, by treatment group and visit.  In addition, the number and percent of patients with 
abnormal values for ALT, AST, and TB will be summarized.  These summaries of patients with 
abnormal values will be performed overall; by normal baseline; and by abnormal baseline for 
each of ALT, AST, and TB. Hy’s law criteria (≥3 × ULN for either ALT or AST, with 
accompanying TB >2 × ULN or patient’s baseline) will also be applied to the data; any potential 
Hy’s law cases will be listed separately.  In the case of patients with Gilbert’s disease, TB will be 
fractionated and the determination of 2 × ULN based upon direct (conjugated) bilirubin.  For 
patients with Gilbert’s Disease 2 × the conjugated bilirubin will be used as the criterion. 
Musculoskeletal Safety 
AEs of muscle-related symptoms will be summarized by treatment group.  CK levels will be 
summarized by the value and change from baseline in the value, by treatment group and visit.  In 
addition, the number and percent of patients with abnormal CK values will be summarized.  
These summaries of patients with abnormal CK will be performed overall; by normal baseline 
CK; and by abnormal baseline CK.  
Diabetes and Hyperglycemia 
Cases of new onset of diabetes will be recorded as AEs and will be summarized using the 
appropriate SOC.  These events will be summarized by severity and relationship to study drug 
for each treatment group.  Glucose and HbA1C will be monitored at baseline and at Weeks 12, 
24, and 52, and be summarized. 
Renal Safety 
Baseline eGFR will be summarized by treatment group for actual value and for baseline eGFR 
categories.  Shift tables of eGFR category from baseline over the study, will be provided by 
treatment group.  Shift tables of urine protein (negative/positive) from baseline over the study, 
will be provided by treatment group.  Values of CK over the study will be summarized by 
treatment group and by baseline eGFR category.  Finally, muscle-related AEs will be 
summarized by treatment group and by baseline eGFR category. 
Neurocognitive Events 
Neurocognitive events will be identified and evaluated by routine safety monitoring of PE 
findings and AEs.  Summarization of neurocognitive events will occur using prespecified 
MedDRA terms and will be performed by SOC, severity, and relationship to study drug for each 
treatment group. 
Clinical Endpoints 
Clinical endpoints using standardized definitions will be adjudicated by an independent blinded 
expert CEC for all ongoing Phase 3 studies in the bempedoic acid program.  Investigator-
reported clinical endpoints and adjudicated clinical endpoints will be summarized by event type 
and treatment group.  Additional details regarding the clinical endpoints and their definitions will 
be included in CEC Charter.

DATA HANDLING AND RECORDKEEPING 
16.1. 
Inspection of Records 
Applicable regulations require the Sponsor (or the Sponsor’s authorized representative) to 
inspect all documents and records to be maintained by the Investigator, including but not limited 
to, medical records (office, clinic, or hospital) for the patients in this study.  These regulations 
also allow the Sponsor’s records to be inspected by authorized representatives of the regulatory 
agencies.  The Investigator will permit study-related monitoring, audits, IRB or IEC review, and 
regulatory inspections by providing direct access to source data/documents.  Direct access 
includes permission to examine, analyze, verify, and reproduce any records and reports that are 
important to the evaluation of a clinical study. 
16.2. 
Retention of Records 
In compliance with the ICH/GCP guidelines, the Investigator/Institution agrees to retain and 
maintain all study records that support the data collected from each patient, as well as all study 
documents as specified in ICH/GCP, Section 8 Essential Documents for the Conduct of a 
Clinical Trial.  The Investigator agrees to contact the Sponsor before destroying or relocating any 
study documentation and is expected to take measures to prevent accidental or premature 
destruction of these documents.  
If the Investigator retires, relocates, or for other reasons withdraws from the responsibility of 
keeping the study records, custody must be transferred to a person who will accept responsibility.  
The Sponsor must be contacted in writing regarding the name and address of the new person 
responsible as well as the disposition of document storage.  Under no circumstances shall the 
Investigator relocate or dispose of any study documents before having obtained written approval 
from the Sponsor. 
Essential records (including eCRFs, source documents, study drug disposition records, signed 
patient ICDs, AE reports, and other regulatory documents) as required by the applicable 
regulations, must be maintained for 2 years after a marketing application is approved for the drug 
for the indication for which it is being investigated; or, if no application is to be filed or if the 
application is not approved for such indication, until 2 years after formal discontinuation of 
clinical development of the investigational product. 
It is the responsibility of the Sponsor to inform the Investigator/Institution as to when these 
documents no longer need to be retained. 
16.3. 
Case Report Forms and Study Records 
Access to eCRFs will be provided to the clinical site. As part of the responsibilities assumed by 
participating in the study, the Investigator agrees to maintain adequate case histories for the 
patients treated as part of the research under this protocol.  The Investigator agrees to maintain 
accurate source documentation and eCRFs as part of the case histories.

Study records are comprised of source documents, eCRFs, and all other administrative 
documents (eg, IRB or IEC correspondence, clinical study materials and supplies shipment 
manifests, monitoring logs, and correspondence).  A study-specific binder will be provided with 
instructions for the maintenance of study records. 
Source documentation is defined as any handwritten or computer-generated document that 
contains medical information or test results that have been collected for or in support of the 
protocol specifications (eg, laboratory reports, clinic notes, study drug disposition log, pharmacy 
records, patient sign-in sheets, patient completed questionnaires, telephone logs, x-rays, and 
ECGs).  All draft, preliminary, and pre/final iterations of a final report are also considered to be 
source documents (eg, faxed and hard copy of laboratory reports, faxed and hard copy of initial 
results, and final report).  
The Investigator agrees to allow direct access to all essential clinical study documents for the 
purpose of monitoring and/or auditing by the Sponsor or its authorized representatives and 
inspection by the appropriate regulatory authorities. 
Data reflecting the patient’s participation with the study drug under investigation are to be 
reported to the Sponsor.  The data are to be recorded on the eCRFs and/or other media provided 
or approved by the Sponsor.  
A completed eCRF must be submitted for each patient who receives study drug, regardless of 
duration.  All supportive documentation submitted with the eCRF, such as laboratory or hospital 
records, should be clearly identified with the study and patient number.  Any personal 
information, including patient name, should be removed or rendered illegible to preserve 
individual confidentiality.  The eCRF should not be used as a source document unless otherwise 
specified by the Sponsor.  
Neither the Sponsor nor a service provider contracted to analyze data and complete the study 
report is permitted to interpret a blank answer; therefore, all fields should be completed.  All 
requested information must be entered on the eCRFs. If an item is not available or is not 
applicable, this fact should be indicated as not available (N/A) or not done (N/D); do not leave a 
field blank.  
Each set of completed eCRFs must be signed and dated by the Investigator acknowledging 
review and that the data are accurate and complete.  The completed database is to be returned to 
the Sponsor as soon as practical after completion by the mechanism prescribed for the protocol. 
It is essential that all dates appearing on the Sponsor’s patient data collection forms for 
laboratory tests, cultures, etc, be the dates on which the specimens were obtained or the 
procedures performed.  The eCRFs will be electronically signed by the Investigator and dated as 
verification of the accuracy of the recorded data.  All data collection forms should be completed 
within a timely manner according to the CRF completion guidelines.

NOTE: For patients who withdraw from IMP treatment, they will continue to have visits according to the protocol schedule. Safety 
assessments should include clinical safety and basic lipid laboratories (except for apoB and hs-CRP), adverse events, PE, vital signs, 
and ECGs. For patients who withdraw from IMP treatment, but refuse to come to the clinic for assessments, assessments will take 
place by phone.  The telephone contacts will occur according the protocol schedule with information regarding current health status 
and to collect information on AEs (eg, recent procedures, hospitalizations, and if the patient has died, the cause of death). 
1 An optional visit between Visits S1 and S2 may be completed if patient fails to meet TG entry criterion. If this optional basic fasting 
(minimum of 10 hours) lipid value visit is completed, the repeat lipid value will be used to determine eligibility. 
2 An optional visit between Visits S1 and S2 may be completed if the patient’s DBP and/or SBP meet the exclusion criteria levels. 
Patients may randomize after blood pressure medications have been adjusted, the patients have been on stable doses of blood pressure 
medications for at least 2 weeks, and the repeat blood pressure values (DBP and/or SBP) do not meet exclusionary values. An optional 
visit between Visit S1 and S2 may be completed to determine eligibility if the patient’s eGFR, ALT, AST, and/or TB meet exclusion 
criteria levels. If this optional visit is completed, the repeated value will be used to determine eligibility. 
3 All procedures will be completed for all patients at either End of Study (EOS) if completing the study or early withdrawal. 
4 Body weight will be measured while fasting, using consistent scales, after voiding, and without shoes and outerwear (eg, coats).  
5 Single 12-lead ECG will be collected prior to any blood sample collection. 
6 Vital signs will include DBP, SBP, and HR and will be collected prior to any blood sample collection. Patient will rest for 5 minutes 
prior to assessments 
7 Serology for HBsAg, HCV  
8 Serum pregnancy test completed in premenopausal women only.  FSH test is completed in women <55 years old and >1 year without 
menses. Urine pregnancy test in women of childbearing potential just prior to randomization.  
9 Clinical safety labs include hematology, blood chemistry, and urinalysis at all visits. Coagulation is included at Screening (Visit S1) 
for all patients, Baseline (Visit T1) and 3-5 days after Visit T1 only if on anticoagulants).  Please refer to laboratory manual for 
detailed schedule of tests.  A local laboratory may be used for assessment at 3-5 days after Visit T1. 
10 Basic fasting (minimum of 10 hours) lipids include total cholesterol, calculated LDL-C, HDL-C, non-HDL-C, and triglycerides.  
11 Diet and exercise counseling per local and/or regional guidelines for the management of hyperlipidemia. 
12 IWRS contact at either an early withdrawal or an EOS visit to register study discontinuation visit date.  
13 Depending upon the length of time between visits, 1 or 2 bottles of study medication will be dispensed as instructed by IWRS. 
14 If patient is discontinuing treatment and completing the EOS visit, but will be continuing in the study either by returning to clinic or 
by phone, continue to schedule study visits for the patient according to the protocol Schedule of Events

1. The text immediately preceding and following a change to the protocol is included for 
each change in order to provide the reviewer with a reference point to identify the change 
in the protocol. 
2. All locations (ie, section numbers and/or header text) refer to the current protocol

5. In the “New Text”, text deleted from the protocol is indicated in strikethrough font. 
Summary and Justification of Changes 
The protocol was amended for the following: 
• Added a line for Amendment 2 version and date to reflect amendment version details. 
• Updated text pertaining to bempedoic acid mechanism of action based on new 
information. 
• Reduced planned patient enrollment from 750 to 525 with 350 randomized to 
bempedoic acid 180 mg and 175 randomized to matching placebo.  Reducing sample 
size has no impact on the statistical power with respect to the efficacy endpoints as 
this study was originally over-sized to provide a higher number for the exposure 
dataset.  The sample size of 350 randomized patients in the bempedoic acid 180 mg 
group and 175 randomized patients in the placebo group is expected to provide more

than 95% power to detect a difference of 15% in the percent change from baseline to 
Week 12 in LDL-C between the bempedoic acid treatment group and the placebo 
group.  This calculation is based on a 2-sided t-test at the 5% level of significance 
(α = 0.05) and a common standard deviation of 15%.  Text and figures where patient 
numbers are presented were updated accordingly. 
• Removed the requirement that strata (statin dose and patient status) could not be 
capped in order to ensure adequate numbers of patient characteristics if imbalance 
occurs. 
• Revised secondary and tertiary endpoints as well as added safety endpoints to more 
accurately describe statistical testing and analysis. 
• Added additional clinical and telephone visits for patients taking simvastatin 40 mg 
based on a request from the Food and Drug Administration (FDA). 
• Added implantable, injectable, or topical method as allowable forms of hormonal 
contraception.  
• Added requirement that women use 2 rather than 1 form of acceptable contraception 
based on a request from the European Heads of Medicines Agency’s Voluntary 
Harmonization Procedure review of another Esperion sponsored protocol.  This 
amendment is to maintain consistency across protocols and is not based on any new 
data with bempedoic acid. 
• Added additional fasting LDL-C assessment (Week -1 (Visit S3) ≥70 mg/dL 
(1.8 mmol/L) after the Run-in period to inclusion criteria.  Removed the allowance of 
repeating a screening LDL-C measurement after Visit S1. 
• Clarified the timing of the collection of lipid values with reference to PCSK9 
inhibitor injections in order to ensure lipid values are obtained at trough levels of 
PCSK9. 
• Further defined inclusion criteria around peripheral arterial disease and 
cerebrovascular atherosclerotic disease. 
• Based on a request from the FDA, added eGFR <45 mL/min/1.73m2 in patients 
taking simvastatin as exclusionary. 
• Based on the extremely long half-live of experimental siRNA inhibitor, Inclisiran, 
excluded patients who have enrolled in a study of an experimental siRNA inhibitor of 
PCSK9. 
• Clarified time period during which subjects should not intend to become pregnant. 
• Altered the 3-month time period for not using the following drugs prior to screening 
based on the half-life of these medications:  expanded mipomersen to 6 months and 
reduced simvastatin to 4 weeks as well as reduced the time period for use of obesity 
medications from 3 months to 4 weeks prior to randomization. 
• Removed collection of optional genetic sampling. 
• Removed collection of reserve samples.

• Removed collection of pharmacokinetic (PK) sample collection on Day 1 and 
clarified that collection needs to be prior to dosing at visits where PK samples are 
collected. 
• Added windows (eg, ± 3 or ± 7 days) to all visits.   
• Removed manufacturing contact details from the protocol and indicated the details 
will be described in the pharmacy manual. 
• Based on a request from the FDA, the monitoring and management of CK values for 
asymptomatic patients was modified.    
• Revised statistical sections to clarify level of significance, standard deviation, and 
methods for imputation of missing data. 
• Added details to clarify the time period and reporting process for collection of AEs 
throughout the protocol as required.   
• Added the following sections to the protocol: 
− Definition of Serious Adverse Event Events or Outcomes not Qualifying as 
Serious Adverse Events 
− Clinical Laboratory Assessments as Adverse Events and Serious Adverse 
Events 
• Made administrative changes throughout the protocol where required to correct 
inconsistencies, add clarification, or correct errors.

Original Text: 
An important differentiating feature of bempedoic acid is that it does not inhibit cholesterol 
synthesis in skeletal muscle.  In addition to preliminary data suggesting that only minor amounts 
of bempedoic acid enter skeletal muscle (<5% of systemic exposure), skeletal muscle does not 
express the enzyme required to activate bempedoic acid to ETC-1002-CoA and inhibit ACL.  
Therefore, bempedoic acid is not anticipated to mediate the adverse effects associated with 
inhibition of biological intermediates within the cholesterol biosynthesis pathway in skeletal 
muscle.

Visit T1 procedures 
If the patient has met all inclusion criteria and none of the exclusion criteria, the patient may be 
randomized into the double-blind treatment period.  Patients who fail to meet any entry criterion 
prior to randomization are considered to be screen failures, will not be randomized into a 
treatment group, and are not required to return for additional visits.  Patients are considered 
randomized once all eligibility criteria are confirmed and a randomization number is obtained by

12.5 
Primary Endpoint; 
The primary efficacy endpoint is the percent change from baseline to Week 12 in LDL-C.  The 
primary efficacy endpoint will be analyzed using analysis of covariance (ANCOVA), with 
treatment group, CV risk (ASCVD only; HeFH with or without ASCVD) and baseline statin 
intensity (high intensity, moderate intensity, low intensity) as factors and baseline LDL-C as a 
covariate.  Baseline LDL-C is defined as the mean of the LDL-C values from Week -1 (Visit S3) 
and predose Day 1/Week 0 (Visit T1).  If a repeat lipid measurement is performed at Week -1 
(Visit S3), then baseline will be the mean of the LDL-C values from the second Week -1 
assessment and predose Day 1/Week 0 (Visit T1).  The ANCOVA will be performed using the 
FAS, with patients included in their randomized treatment group regardless of the treatment they 
actually received.  Two methods for data handling will be used: the first is observed case data 
only, while the second will involve specification of the missing data mechanism using a pattern 
mixture model (PMM).  The primary analysis will be that from the PMM, while the observed 
case analysis will be used as confirmatory.  The PMM will be used to specify different 
imputation strategies depending on whether the patient is still on study treatment.  The PMM will 
be used to specify different imputation strategies depending on whether the patient is still on 
study treatment.  Patients with missing LDL-C data at Week 12 who are no longer taking study 
treatment can be assumed to no longer be benefitting from study medication, and their missing 
value(s) can be assumed to be returning toward their baseline value.  In this instance, it is 
reasonable to impute LDL-C values based on the patients’ baseline value.  Patients with missing 
LDL-C data at Week 12 who are still taking study treatment can be assumed to continue to 
benefit from study medication, and their missing value(s) can be assumed to be similar to those 
who remain on study treatment and have data.  In this instance, it is reasonable to impute LDL-C 
values based on the observed values in their randomized treatment group at Week 12.  To 
account for uncertainty, missing values will be imputed using multiple imputation. 
Imputed datasets will be analyzed using ANCOVA with treatment group, CV risk (ASCVD 
only; HeFH with or without ASCVD) and baseline statin intensity (high intensity, moderate 
intensity, low intensity) as factors and baseline LDL-C as a covariate.  Approximately 
100 imputed datasets will be created, with results from the analysis of each imputed dataset 
combined using Rubin’s method.  For each type of ANCOVA (observed case; imputation via 
PMM), the least squares mean (LSM) and standard error (SE) will be provided for both treatment 
groups, along with the placebo-corrected LSM, its 95% CI and associated p-value.   
12.6 
Secondary and Tertiary Efficacy Endpoints 
Secondary efficacy endpoints are also of interest for this study, in terms of controlling the overall 
Type I error rate.  A gatekeeping or stepdown approach will be used to test the primary efficacy 
endpoint and then specific secondary efficacy endpoints sequentially in order to preserve the 
study-wise Type I error rate.  The sequence for the stepdown procedure in this study is as 
follows: 
1. Test the primary efficacy endpoint: percent change from baseline to Week 12 in LDL-C

2. Test the percent change from baseline to Week 24 in LDL-C 
3. Test the percent change from baseline to Week 12 in non-HDL-C 
4. Test the percent change from baseline to Week 12 in TC 
5. Test the percent change from baseline to Week 12 in apoB 
6. Test the percent change from baseline to Week 12 in hs-CRP   
In this hierarchical testing structure, each hypothesis is tested at a significance level of 0.05, two-
sided.  Statistical significance at each step is required in order to test the next hypothesis.  If the 
primary endpoint meets the criteria for statistical significance, then the percent change from 
baseline to Week 24 in LDL-C will be tested; and so forth. 
Percent change from baseline to Weeks 24 and 52 in LDL-C; change from baseline to Weeks 12, 
24, and 52 in LDL-C; percent change from baseline to Weeks 12, 24, and 52, in HDL-C, non-
HDL-C, TG, TC, apoB, and hs-CRP will each be analyzed using ANCOVA with treatment 
group, CV risk (ASCVD only; HeFH with or without ASCVD) and baseline statin intensity 
(high intensity, moderate intensity, low intensity) as factors and the relevant baseline as a 
covariate.  Baseline for HDL-C, non-HDL-C, TG, and TC will be defined as the mean of the 
lipid values from Week -1 (Visit S3) and predose Day 1/Week 0 (Visit T1).  If a repeat lipid 
measurement is performed at Week -1 (Visit S3), then baseline will be the mean of the lipid 
values from the second Week -1 assessment and predose Day 1/Week 0 (Visit T1).  Baseline for 
apoB and hs-CRP will be defined as the predose Day 1/Week 0 (Visit T1) value.  Each 
ANCOVA will be performed using the FAS, with patients included in their randomized 
treatment group regardless of the treatment they actually received.  Only observed case data will 
be included in each analysis (no imputation will be performed for missing data).  For each lipid 
parameter and analysis time point, the LSM and SE will be provided for both treatment groups, 
along with the placebo-corrected LSM, its 95% CI and associated p-value. 
For all continuous efficacy endpoints (percent change from baseline in LDL-C, HDL-C, non-
HDL-C, TC, TG, apoB, and hs-CRP; change from baseline in LDL-C; to Weeks 12, 24, and 52 
as appropriate), the ANCOVA assumption of normality will be assessed.  If non-normality of the 
data is found at any time point for any parameter, either the data will be transformed so that it is 
normally distributed or a nonparametric test will be used instead of the planned ANCOVA. 
Percent change from baseline to Week 24 and to Week 52 LDL-C will be analyzed similarly 
with patients in the FAS who did not receive additional lipid-lowering therapy by that time point 
(by Week 24 for the Week 24 analysis; by Week 52 for the Week 52 analysis) included in the 
analyses. Only observed case data will be used (no imputation for missing data). Output from 
each time point will include the LSM and SE for each treatment group, as well as the placebo-
correct LSM, 95% CI, and p-value.

and predose Day 1/Week 0 (Visit T1).  If a repeat lipid measurement is performed at Week -1 
(Visit S3), then baseline will be the mean of the LDL-C values from the second Week -1 
assessment and predose Day 1/Week 0 (Visit T1). If only one value is available, then that single 
value will be used for baseline.  The details of the ANCOVA model and options to correct for 
unequal variances and group size will be described in the SAP. 
Missing data for the primary endpoint will be imputed using a multiple imputation method 
that accounts for treatment adherence.  A pattern mixture model (PMM) will be used to 
specify different imputation strategies depending on whether the patient is still on study 
treatment.  Imputed datasets will be analyzed using ANCOVA with treatment group, CV risk 
(ASCVD only; HeFH with or without ASCVD) and baseline statin intensity (high intensity, 
moderate intensity, low intensity) as factors as factors and baseline LDL-C as a covariate.  
Approximately 200 imputed datasets will be created, with results from the analysis of each 
imputed dataset combined using Rubin’s method.  The least squares mean (LSM) and 
standard error (SE) will be provided for both treatment groups, along with the placebo-
corrected LSM, its 95% confidence interval (CI), and associated p-value.  A confirmatory 
analysis using observed data only will also be performed for the primary endpoint. Details for 
PMM and multiple imputation will be descried in the SAP. To account for uncertainty, missing 
values will be imputed using multiple imputation. 
The ANCOVA will be performed using the FAS, with patients included in their randomized

whether the patient is still on study treatment.  The PMM will be used to specify different 
imputation strategies depending on whether the patient is still on study treatment.  Patients with 
missing LDL C data at Week 12 who are no longer taking study treatment can be assumed to no 
longer be benefitting from study medication, and their missing value(s) can be assumed to be 
returning toward their baseline value.  In this instance, it is reasonable to impute LDL C values 
based on the patients’ baseline value.  Patients with missing LDL C data at Week 12 who are 
still taking study treatment can be assumed to continue to benefit from study medication, and 
their missing value(s) can be assumed to be similar to those who remain on study treatment and

Key secondary efficacy endpoints are also of interest for this study, in terms of controlling the 
overall Type I error rate.  A gatekeeping or stepdown approach will be used to test the primary 
efficacy endpoint and then specific secondary efficacy endpoints sequentially in order to 
preserve the study-wise Type I error rate.  The sequence for the stepdown procedure in this study 
is as follows: 
1. Test the primary efficacy endpoint: percent change from baseline to Week 12 in LDL-C  
2. Test the percent change from baseline to Week 24 in LDL-C 
3. Test the percent change from baseline to Week 12 in non-HDL-C

5. Test the percent change from baseline to Week 12 in apoB

In this hierarchical testing structure, each hypothesis is tested at a significance level of 0.05, two-
sided.  Statistical significance at each step is required in order to test the next hypothesis.  If the 
primary endpoint meets the criteria for statistical significance, then the percent change from 
baseline to Week 24 in LDL-C will be tested; and so forth. 
In general, change or percent change in lipid parameters at a given time point will be analyzed 
using similar ANCOVA model for the primary endpoint Percent change from baseline to 
Weeks 24 and 52 in LDL C; change from baseline to Weeks 12, 24, and 52 in LDL C; percent 
change from baseline to Weeks 12, 24, and 52, in HDL C, non HDL C, TG, TC, apoB, and 
hs CRP will each be analyzed using ANCOVA with treatment group, CV risk (ASCVD only; 
HeFH with or without ASCVD) and baseline statin intensity (high intensity, moderate intensity, 
low intensity) as factors and the relevant baseline as a covariate.   
Baseline for HDL-C, non-HDL-C, TG, and TC will be defined as the mean of the lipid values 
from Week -1 (Visit S3) and predose Day 1/Week 0 (Visit T1).  If a repeat lipid measurement is 
performed at Week -1 (Visit S3), then baseline will be the mean of the lipid values from the 
second Week -1 assessment and predose Day 1/Week 0 (Visit T1).  Baseline for apoB and 
hs-CRP will be defined as the predose Day 1/Week 0 (Visit T1) value.   
Each ANCOVA will be performed using the FAS, with patients included in their randomized 
treatment group regardless of the treatment they actually received.  Same imputation method 
described for the primary endpoint will be used for those secondary endpoints included in the 
step-down procedure, while only observed data analysis will be used for other secondary and 
tertiary endpoints. Only observed case data will be included in each analysis (no imputation will 
be performed for missing data).  For each lipid parameter and analysis time point, the LSM and 
SE will be provided for both treatment groups, along with the placebo-corrected LSM, its 95% 
CI and associated p-value. 
For all continuous efficacy endpoints (percent change from baseline in LDL C, HDL C, non

as appropriate), 
Tthe ANCOVA assumption of normality will be assessed.  If non-normality of the data is found

NOTE: For patients who withdraw from IMP treatment, but consent to be followed for safety assessments and return to clinic for these 
visit, the visits will occur according to the protocol schedule. Safety assessments should include clinical safety and basic lipid 
laboratories (except for apoB and hs-CRP), adverse events, PE, vital signs, and ECGs. For patients who withdraw from IMP treatment, 
but consent to be followed for safety assessments by phone, the telephone contacts will occur according the protocol schedule with 
information regarding current health status and to collect information on AEs (eg, recent procedures, hospitalizations, and if the 
patient has died, the cause of death). If a patient does not provide consent to be followed for safety assessments per the protocol (either 
by returning to clinic or by phone), Visit T7 will be considered the EOS/Early Withdrawal from study and no further visits will be 
scheduled. 
1 An optional visit approximately 1 week later MAY be completed if patient fails to meet a lipid entry criterion. If this optional basic 
fasting (minimum of 10 hours) lipid value visit is completed, the mean of the first value and repeat lipid value will be used to 
determine eligibility. 
2 An optional visit between Visits S1 and T1 may be completed if the patient’s DBP and/or SBP meet the exclusion criteria levels. 
Patients may randomize after blood pressure medications have been adjusted, the patients have been on stable doses of blood pressure 
medications for at least 2 weeks, and the repeat blood pressure values (DBP and/or SBP) do not meet exclusionary values. An optional 
visit between Visit S1 and T1 may be completed to determine eligibility if the patient’s eGFR, ALT, AST, and/or TB meet exclusion 
criteria levels. If this optional visit is completed, the repeated value will be used to determine eligibility. 
3 All procedures will be completed for all patients at either End of Study (EOS) if completing the study or early withdrawal. 
4 Body weight will be measured while fasting, using consistent scales, after voiding, and without shoes and outerwear (eg, coats).  
5 Single 12-lead ECG will be collected prior to any blood sample collection.

9 Clinical safety labs include hematology, blood chemistry, and urinalysis at all visits. Coagulation is included at Screening (Visit S1), 
Baseline (Visit T1) only if on anticoagulants).  Please refer to laboratory manual for detailed schedule of tests. 
10 Basic fasting (minimum of 10 hours) lipids include total cholesterol, calculated LDL-C, HDL-C, non-HDL-C, and triglycerides. 
Repeat within 1 week if exceed protocol-specified criteria. 
11 Diet and exercise counseling per local and/or regional guidelines for the management of hyperlipidemia. 
12 IWRS contact at either an early withdrawal or an EOS visit to register study discontinuation visit date.  
13 Depending upon the length of time between visits, 1 or 2 bottles of study medication will be dispensed as instructed by IWRS. 
14 If patient is discontinuing treatment and completing the EOS visit, but will be continuing in the study either by returning to clinic or 
by phone, continue to schedule study visits for the patient according to the protocol Schedule of Events

SUMMARY OF CHANGES 
CLINICAL STUDY PROTOCOL 
Study Number: 
1002-047 
Study Title: 
A Long-term, Randomized, Double-blind, Placebo-
controlled, Multicenter Study to Evaluate the Efficacy of 
Bempedoic Acid (ETC-1002) in Patients with 
Hyperlipidemia at High Cardiovascular Risk Not 
Adequately Controlled by Their Lipid-Modifying Therapy 
Protocol Version Incorporating 
Current Summary of Changes: 
Amendment 3:  09 May 2017 
Preceding Protocol Version: 
Amendment 2:  22 March 2017 
Investigational Product Name: 
ETC-1002 
Conventions used in this Summary of Changes Document 
1. The text immediately preceding and following a change to the protocol is included for 
each change in order to provide the reviewer with a reference point to identify the change 
in the protocol. 
2. All locations (ie, section numbers and/or header text) refer to the current protocol 
version, which incorporates the items specified in this Summary of Changes document. 
3. The original text is from the preceding protocol version. 
4. In the “New Text”, all substantive text added to the protocol is bolded and italicized. 
5. In the “New Text”, text deleted from the protocol is indicated in strikethrough font. 
Summary and Justification of Changes 
The protocol was amended for the following: 
• Added a line for Amendment 3 version and date to reflect amendment version details. 
• Prohibited use of simvastatin ≥40 mg/day 
 
 
 The protocol has been 
amended to exclude patients receiving simvastatin ≥40 mg and remove study visits at 
Weeks 16, 20, 28, and 32 that were only for patients taking simvastatin 40 mg/day.  A 
letter was provided to all investigators with instructions on how to proceed for 
enrolled patients receiving simvastatin 40 mg/day.

• Increased number of patients to be enrolled from approximately 525 to approximately 
750 with 500 randomized to bempedoic acid and 250 randomized to matching 
placebo as was included in the original protocol and Amendment 1.  The reason for 
the increase in patients is due to the recent decision to discontinue IMP in patients 
receiving simvastatin 40 mg/day across our program. Based on this decision, the 
safety database will be smaller than anticipated; therefore, we would like to increase 
the number of patients in this protocol to 750 as originally planned to ensure a robust 
safety database. 
• Clarified that the requirement to have ≥80% treatment compliance during the Run-in 
Period refers to the average treatment compliance over the entire Run-in Period 
(compliance measured at Visits S3 and T1). 
• Corrected the visit window for Week 24 within the protocol text and Appendix 1, 
Schedule of Events, to reflect 168 ± 7 days.  
• Updated the definition of SAEs to include hospitalizations for preplanned surgeries 
and/or elective surgeries.

Section 6.2, Study Hypothesis 
Original Text: 
The study will assess the 12-week efficacy of bempedoic acid in decreasing LDL-C versus 
placebo in addition to maximally tolerated lipid-lowering therapy, including a maximally 
tolerated statin alone or in combination with other lipid-lowering therapies, in patients with 
hyperlipidemia.  The randomized, double-blind, placebo-controlled add-on to maximally 
tolerated lipid-lowering therapy design will ensure that efficacy data are meaningful and 
interpretable.  The treatment duration (52 weeks) and large patient number (n = 525) will provide 
robust long-term data on lipid profile, safety, and tolerability in high CV risk patients who have 
an unmet medical need for additional lipid-lowering therapy, such as bempedoic acid once daily, 
orally bioavailable option.

An adjunctive therapy plan is in place for those patients whose LDL-C values meet the protocol-
defined LDL-C threshold criteria. Post-randomization, LDL-C results will be masked to 
investigators in order to maintain the blind; however, the following thresholds have been set to 
notify investigators and provide an opportunity to adjust the patient’s standard of care regimen.  
• Beginning at Week 24 (Visit T5) visit and for the duration of the study, the central 
laboratory will notify the investigator when the patient’s LDL-C value is >170 mg/dL 
(4.4 mmol/L) and ≥25% from the patient’s baseline value at Week 0 (Visit T1) 
• Upon receiving notification from the central laboratory that the patient has met or 
exceeded the threshold criteria for LDL-C, the investigator will initiate the following 
adjunctive therapy plan: 
− Patients will be scheduled to return to the clinic within 1 week for a repeat fasting 
blood lipid sample to confirm that the LDL-C value meets the threshold criteria  
− After confirming that the LDL-C value meets or exceeds the threshold criteria, the 
investigator will adjust the patient’s lipid-lowering treatment regimen per 
standard-of-care and local practice, with the exception of simvastatin at daily 
doses greater than 40 mg and the fibrate gemfibrozil. The patient’s LDL-C will be 
re-evaluated at the next scheduled clinic visit as defined in the Schedule of Visits 
(Appendix 1).

DEFINITION OF SAES AND OUTCOMES NOT QUALIFYING AS 
SERIOUS ADVERSE EVENT CHANGES 
Location: 
Section 11.2.7.1, Definition of Serious Adverse Event; Section 11.2.7.2, Definition of Outcomes 
not Qualifying as Serious Adverse Events 
Original Text: 
An SAE is defined as any AE occurring at any dose that results in any of the following 
outcomes:  
• Results in death 
• Is life threatening 
• Requires in-patient hospitalization or prolongation of existing hospitalization 
• Results in persistent or significant disability/incapacity, or substantial disruption of the 
ability to conduct normal life functions 
• Is a congenital anomaly/birth defect 
• An important medical event 
NOTE:  Hospitalization is defined as a formal inpatient admission.  This will not include 
admissions under “23-hour Observational Status”, an Emergency Room visit without hospital 
admission or an Urgent Care visit and therefore, such events will not be recorded as an SAE 
under this criterion, nor will hospitalization for an elective or outpatient procedure scheduled or 
planned before signing of informed consent.  However, unexpected complications and/or 
prolongation of hospitalization that occur during elective or outpatient surgery should be 
recorded as AEs and assessed for seriousness.  Admission to the hospital for social or situational 
reasons (eg, no place to stay, live too far away to come for hospital visits) will not be considered 
inpatient hospitalizations.

Definition of Serious Adverse Event Events or Outcomes not Qualifying as 
Serious Adverse Events 
The following are not considered SAEs and therefore do not need to be reported as such: 
• Preplanned or elective hospitalization including social and/or convenience situations 
(eg, due to inclement weather) 
• Overdose of either Esperion study drug or concomitant medication unless the event 
meets SAE criteria (eg, hospitalization).  However, the event should still be captured 
as a nonserious AE on the appropriate eCRF page

NOTE: For patients who withdraw from IMP treatment, they will continue to have visits according to the protocol schedule. Safety 
assessments should include clinical safety and basic lipid laboratories (except for apoB and hs-CRP), adverse events, PE, vital signs, 
and ECGs. For patients who withdraw from IMP treatment, but refuse to come to the clinic for assessments, assessments will take 
place by phone.  The telephone contacts will occur according the protocol schedule with information regarding current health status 
and to collect information on AEs (eg, recent procedures, hospitalizations, and if the patient has died, the cause of death). 
* Patients receiving simvastatin 40 mg will have clinic visits performed at weeks 16 and 28 and telephone visits at Weeks 20 and 32.  At 
clinic visits at Weeks 16 and 28, perform clinical safety labs as defined in Footnote 9, assess adverse events and review changes in 
concomitant medications.  At telephone visits performed at Weeks 20 and 32, assess adverse events and review changes in 
concomitant medications.   
1 An optional visit between Visits S1 and S2 may be completed if patient fails to meet TGTG entry criterion. If this optional basic 
fasting (minimum of 10 hours) lipid value visit is completed, the repeat lipid value will be used to determine eligibility. 
2 An optional visit between Visits S1 and S2 may be completed if the patient’s DBP and/or SBP meet the exclusion criteria levels. 
Patients may randomize after blood pressure medications have been adjusted, the patients have been on stable doses of blood pressure 
medications for at least 2 weeks, and the repeat blood pressure values (DBP and/or SBP) do not meet exclusionary values. An optional 
visit between Visit S1 and S2 may be completed to determine eligibility if the patient’s eGFR, ALT, AST, and/or TB meet exclusion 
criteria levels. If this optional visit is completed, the repeated value will be used to determine eligibility. 
3 All procedures will be completed for all patients at either End of Study (EOS) if completing the study or early withdrawal. 
4 Body weight will be measured while fasting, using consistent scales, after voiding, and without shoes and outerwear (eg, coats).  
5 Single 12-lead ECG will be collected prior to any blood sample collection. 
6 Vital signs will include DBP, SBP, and HR and will be collected prior to any blood sample collection. Patient will rest for 5 minutes 
prior to assessments 
7 Serology for HBsAg, HCV  
8 Serum pregnancy test completed in premenopausal women only.  FSH test is completed in women <55 years old and >1 year without 
menses. Urine pregnancy test in women of childbearing potential just prior to randomization.  
9 Clinical safety labs include hematology, blood chemistry, and urinalysis at all visits. Coagulation is included at Screening (Visit S1) 
for all patients, Baseline (Visit T1) and 3-5 days after Visit T1 only if on anticoagulants).  Please refer to laboratory manual for 
detailed schedule of tests.  A local laboratory may be used for assessment at 3-5 days after Visit T1. 
10 Basic fasting (minimum of 10 hours) lipids include total cholesterol, calculated LDL-C, HDL-C, non-HDL-C, and triglycerides.  
11 Diet and exercise counseling per local and/or regional guidelines for the management of hyperlipidemia. 
12 IWRS contact at either an early withdrawal or an EOS visit to register study discontinuation visit date.  
13 Depending upon the length of time between visits, 1 or 2 bottles of study medication will be dispensed as instructed by IWRS. 
14 If patient is discontinuing treatment and completing the EOS visit, but will be continuing in the study either by returning to clinic or 
by phone, continue to schedule study visits for the patient according to the protocol Schedule of Events
