In the case of proprotein convertase subtilisin/kexin type 9 (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.

cardiovascular events. 
• 
Primary Prevention patients must as a minimum have a history of requiring lipid-modifying 
therapy based on local guidelines (for example, American College of Cardiology 
[ACC]/American Heart Association [AHA] guidelines, European Society of Cardiology 
[ESC]/European Atherosclerosis Society [EAS] guidelines, Canadian Cardiovascular Society 
guidelines). 
• 
Secondary prevention and/or HeFH patients must include those with a history of: 
− 
HeFH, defined by: 
− 
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 5)

screening (Week -5 Visit S1). 
6. Patient reported SI defined as an inability to tolerate 2 or more statins, one at a low dose, due to an 
adverse safety effect that started or increased during statin therapy and resolved or improved when 
statin therapy was discontinued.  
Low-dose statin therapy is defined as an average daily dose of rosuvastatin 5 mg, atorvastatin 10 mg, 
simvastatin 10 mg, lovastatin 20 mg, pravastatin 40 mg, fluvastatin 40 mg, or pitavastatin 2 mg.  
Please note that patients currently tolerating very-low-dose statin therapy (an average daily dose of 
rosuvastatin <5 mg, atorvastatin <10 mg, simvastatin <10 mg, lovastatin <20 mg, pravastatin <40 mg, 
fluvastatin <40 mg, or pitavastatin <2 mg) are considered to be intolerant to that low-dose statin. 
Patients may continue taking very-low-dose statin therapy throughout the study provided that it is 
stable (used for at least 4 weeks prior to Screening Visit S1) and well tolerated.  
7. Written confirmation by both patient and principal investigator that the patient is statin intolerant as 
defined above and aware of the benefit of statin use to reduce the risk of MACE including 
cardiovascular death. 
Key exclusion criteria 
1. Total fasting (minimum of 10 hours) TG ≥500 mg/dL (5.6 mmol/L at Week -5 (Visit S1). 
Note:  A single repeat, fasting (minimum of 10 hours) of TG may be completed prior to initiation of 
the single-blind Run-in period.  For those patients who have a repeat TG, the repeat value will be 
used to determine eligibility. 
2. Renal dysfunction or a glomerulonephropathy, 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). 
Note: A single repeat of eGFR may be completed between Visits S1 and S2.  For those patients who 
have a repeat eGFR, the repeat value 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), coronary artery bypass graft (CABG), percutaneous coronary intervention (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/or 
diastolic blood pressure (DBP) ≥100 mmHg measured according to local standards. 
Note: At the discretion of the investigator, the time between Visits S1 and S2 can be extended by 
4 weeks for adjustments in blood pressure (BP) medications and/or additional assessment of BP, with 
the repeat assessment value used to determine eligibility.  Alternatively, patients can be rescreened if 
BP status has changed. 
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, AST, and/or TB 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 
optional 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 
bypass) that may affect drug absorption. 
10. Hematologic or coagulation disorders or a hemoglobin (Hgb) level <10 g/dL at Week -5 (Visit S1).   
11. Persistent poor compliance or lack of tolerance with single-blind, placebo study drug (ie, ingesting 
<80% average of planned doses) assessed at the T1 visit prior to randomization. 
12. Active malignancy, including those requiring surgery, chemotherapy, and/or radiation in the past 
5 years.  Non-metastatic basal or squamous cell carcinoma of the skin and cervical carcinoma in situ

Safety and Monitoring: 
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: 
• 
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 investigational medicinal product (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) 
Potential AEs: 
Based on findings in nonclinical models, potential AEs include reversible hypoglycemia and 
metabolic acidosis.  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.  
Hepatic:  
Hepatic function will be monitored throughout with the clinical safety labs.  More detailed 
investigation will occur per the instructions in the protocol body if the safety clinical laboratory 
results are 3 times or more than the ULN.  
Renal:   
Renal function will be monitored throughout with clinical safety labs.  More detailed instructions are 
in the protocol body. 
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, standard vital 
signs, and ECGs. 
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.

Analysis Populations 
The Full Analysis Set (FAS), used for all of the efficacy 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 the treatment they actually received. 
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.   
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 and 
patient type (primary prevention; secondary prevention) 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 the treatment and patient type 
(primary prevention; secondary prevention) 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. 
For the remaining secondary efficacy endpoints and the tertiary efficacy endpoints, a significance level of 
0.05 will be used; given the large number of remaining endpoints, the p-values for those endpoints will be 
considered descriptive.

hs-CRP will each be analyzed using ANCOVA with treatment group and patient type (primary 
prevention; secondary prevention) as factors and the relevant baseline as a covariate.  Baseline for 
non-HDL-C,
 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).  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,
 non-HDL-C, TC, 
 apoB, and hs-CRP; change from baseline in LDL-C; to Weeks 12 and 24, 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. 
Additional Post-randomization Adjunctive Triglyceride-lowering Therapy: 
The number and percent of patients in each treatment group requiring additional (post-randomization) 
TG-lowering therapy will be summarized.  The medications will be summarized by treatment group. 
Safety Analyses 
The summarization of AEs will include TEAEs.  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 post baseline time point. 
Hepatic Safety 
For liver-associated enzymes and TB, the number and percent of patients with abnormal values for ALT, 
AST, and TB will be summarized.  Hy’s law criteria (≥3 × ULN for either ALT or AST, with 
accompanying TB >2 × ULN in the absence of other known causes) will also be applied to the data; any 
potential Hy’s law cases will be listed separately.  For patients with Gilbert’s disease, conjugated (direct 
bilirubin) will be used for the evaluation.   
Musculoskeletal Safety 
AEs of muscle-related symptoms will be summarized by treatment group.  In addition, the number and 
percent of patients with abnormal CK values will be summarized.   
Diabetes/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.

Renal Safety 
Baseline eGFR and values of CK will be summarized by treatment group and by baseline eGFR 
categories.  Shift tables of eGFR category from baseline over the study, will be provided by treatment 
group.  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 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.   
Pharmacokinetics 
Three pharmacokinetic (PK) samples will be collected.  Plasma concentrations of bempedoic acid and its 
metabolite ESP15228 will be determined in patients who are receiving bempedoic acid, who have 
compliance ≥80%, and who have taken a dose of bempedoic acid within 2 days of the sample collection.  
All patients, site personnel, and study personnel will remain blinded to treatment assignment throughout 
the duration of the study.  Personnel performing the bioanalytical analysis of bempedoic acid 
concentrations will be unblinded in order to assay the appropriate samples during the study.  Plasma 
concentrations of bempedoic acid and ESP15228 will be summarized using descriptive statistics by time 
point.

INTRODUCTION 
4.1. 
Overview of the Disease Under Study 
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 risk unable to meet their treatment goals with currently 
available lipid-lowering therapies. 
More people die annually from cardiovascular disease (CVD) than from any other disease.  CVD 
remains the leading cause of death among Europeans, Americans, and other populations around 
the world (WHO 2015).  In the United States (US), based on 2011 data, more than 
2,150 Americans die from CVD per day, an average of 1 death every 40 seconds (Mozffarian 
2015).  The relationship between CVD and elevations in LDL-C is undisputed.  Many clinical 
studies have demonstrated that lowering elevated levels of LDL-C reduces the risk of heart 
attacks, stroke, and death (Baigent 2010).  More than half of the adult population has high 
cholesterol; therefore, lowering elevated LDL-C is a very important step in the battle against 
heart disease.  It is also known that elevation of high-sensitivity C-reactive protein (hs-CRP; a 
measure of systemic inflammation) has been associated with increased cardiovascular (CV) risk 
(Bikdeli 2011; Vidula 2008), and lowering hs-CRP with statin therapy—independent of the level 
of LDL-C achieved with the statin treatment—significantly reduces recurrent coronary events 
(Ridker 2005).  Given the evidence, hs-CRP is included as a risk indicator in the Reynolds Risk 
algorithm (Ridker 2007) and in clinical practice guidelines for the management of dyslipidemia 
(Jacobson 2014; Stone 2013).  The Reynolds Risk score, which includes hs-CRP, has proved to 
be an excellent CV risk assessment tool (DeFilippis 2011). 
The use of HMG-CoA reductase inhibitors, or statins, is one of the most important advances in 
the management of CVD, decreasing CV morbidity and mortality by approximately 25% in 
eligible patients (Joy 2009).  However, tolerability is an important barrier to statin adherence.  
Muscle complaints, which encompass a range of conditions from myalgia to rare but life-
threatening rhabdomyolysis, represent a major cause of statin discontinuation in clinical practice 
(Joy 2009).  In addition, a range of other signs and symptoms may lead to discontinuation, 
including elevated liver enzymes, gastric upset, diarrhea, constipation, rash, headache, dizziness, 
mental confusion, forgetfulness, and erectile dysfunction (Eckel 2010).  The statin intolerant (SI) 
patient population constitutes a major public health concern.  
Guidelines now recommend very aggressive lowering of LDL-C in high-risk individuals to 
levels below 100 mg/dL and often under 70 mg/dL (Jacobson 2014) or reduction of ≥50% 
(Stone 2013).  Worldwide, statins are used by tens of millions in order to achieve these 
aggressive lipid goals.  Recent guidelines for the treatment of hypercholesterolemia are likely to 
further increase the number of patients taking statins, possibly to as many as 1 in 3 American 
adults.  Consequently, as the number of statin-treated patients grows, the problem of statin 
intolerance will increase in importance as a public health concern.  Current guidelines recognize 
that some patients develop intolerable side effects with statins.  These guidelines recommend

patients be treated with the maximum-appropriate intensity of a statin that does not cause adverse 
effects (Stone 2013).  
4.2. 
Overview of 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-coenzyme 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 LDL receptor (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. 
Pharmacokinetics and Pharmacology 
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 bempedoic acid and 
ESP15228 increased in proportion to increasing dose.  The terminal elimination half-life (t½) 
ranged from 15 to 27 hours for bempedoic acid and 20 to 33 hours for ESP15228. 
In clinical drug-drug interaction studies, bempedoic acid 240 mg showed less than a 2-fold 
increase in the exposure of atorvastatin 10 mg, simvastatin 20 mg, pravastatin 40 mg, and 
rosuvastatin 10 mg in 2 statin drug-drug interaction studies (Studies 1002-007 and 1002-012).  
This increase was generally less pronounced when bempedoic acid 180 mg was administered 
with high dose statins (atorvastatin 80 mg, simvastatin 40 mg, pravastatin 80 mg, and 
rosuvastatin 40 mg) in Study 1002-037, suggesting that the combination is unlikely to alter 
safety profile of statins.  No drug interaction occurred between daily bempedoic acid 180 mg and 
metformin in patients with type 2 diabetes mellitus (T2DM).  A Phase 2 study evaluated and 
showed no effect of ezetimibe 10 mg on steady-state trough bempedoic acid plasma 
concentrations in 40 patients with hypercholesterolemia randomized to receive bempedoic acid 
plus ezetimibe (Study 1002-008).  Results of a drug interaction study in 19 patients (16 evaluable 
for pharmacokinetics [PK]) with the oral contraceptive Ortho-Novum 1/35 in healthy women 
demonstrate no effect of daily bempedoic acid 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.

Approximately 300 patients with a history of SI will be stratified based on patient type (primary 
prevention; secondary prevention) and randomized at Week 0 (Visit T1) in a 2:1 ratio to receive 
either bempedoic acid 180 mg (n = 200) or matching placebo (n = 100) once daily for 24 weeks.  
Randomized patients will return for clinic visits at Week 4 (Visit T2), Week 12 (Visit T4), and 
Week 24 (Visit T5).  A phone visit will occur at Week 8 (Visit T3).   
An independent expert Data Monitoring Committee (DMC) will formally review accumulating 
unblinded safety data from this and other ongoing Phase 3 studies of bempedoic acid.  All 
clinical endpoints, including all major 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), will be adjudicated by an independent blinded 
expert Clinical Events Committee (CEC), using standardized definitions.  
For details of study assessments, see the Schedule of Events in Section 8.3. 
6.2.1. 
Inclusion Criteria 
1. Provision of written informed consent must be obtained prior to any study-specific 
procedure. 
2. Men and nonpregnant, nonlactating women.  Women must be either:

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. 
5. Requiring statin therapy for the purpose of primary or secondary prevention of

6. Patient-reported SI defined as an inability to tolerate 2 or more statins, one at a low dose, 
due to an adverse safety effect that started or increased during statin therapy and resolved 
or improved when statin therapy was discontinued.  
Low-dose statin therapy is defined as an average daily dose of rosuvastatin 5 mg, 
atorvastatin 10 mg, simvastatin 10 mg, lovastatin 20 mg, pravastatin 40 mg, fluvastatin 
40 mg, or pitavastatin 2 mg.  
Please note that patients currently tolerating very-low-dose statin therapy (an average 
daily dose of rosuvastatin <5 mg, atorvastatin <10 mg, simvastatin <10 mg, lovastatin 
<20 mg, pravastatin <40 mg, fluvastatin <40 mg, or pitavastatin <2 mg) are considered to 
be intolerant to that low-dose statin. Patients may continue taking very-low-dose statin 
therapy throughout the study provided that it is stable (used for at least 4 weeks prior to 
screening, S1) and are taken at a consistent time each day. 
7. Written confirmation by both patient and principal investigator that the patient is statin 
intolerant as defined above and aware of the benefit of statin use to reduce the risk of 
MACE including cardiovascular death.

replacement therapy for at least 6 weeks prior to randomization are allowed.  
8. Liver disease or dysfunction, including: 
• Positive serology for hepatitis B surface antigen (HBsAg) and/or hepatitis C 
antibodies (HCV-ABVivi) at Week -5 (Visit S1). 
• Alanine aminotransferase (ALT), aspartate aminotransferase (AST) ≥2 × ULN, 
and/or total bilirubin (TB) ≥1.2 × ULN at Week -5 (Visit S1).  If TB ≥1.2 × ULN, a 
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, AST, and/or TB 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 optional reflexive test for hepatitis C ribonucleic acid (RNA) is 
negative, patient can be enrolled.

6.3. 
Patient Identification, Randomization, and Blinding 
Patient identification numbers will be assigned sequentially by interactive web response system 
(IWRS) at the time of informed consent during the screening module transaction.  
For patients who satisfy all entry criteria and complete the 5-week screening period, 
randomization will occur at Week 0 (Visit T1).  Patients will be stratified on primary prevention 
or secondary prevention 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 or 
• matching placebo 
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.   
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

Page 37 of 153 
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.

INVESTIGATIONAL MEDICINAL PRODUCT  
7.1. 
Investigational Medicinal Product Supply and Control 
The Sponsor will supply the investigational medicinal product (IMP) for this study.  The IMP for 
this study includes bempedoic acid (180-mg film-coated tablets) and matching placebo (film-
coated tablets).  IMP will be distributed and released in accordance with regional and local 
requirements during the conduct of the study. 
The medication identification (MED ID) number (an identifier on the study drug packaging) will 
be obtained via IWRS and used to select placebo study drug 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 (one 100-day supply bottle) to patients by appropriate clinical site 
personnel at Week 0 (Visit T1), and Week 12 (Visit T4). 
Please see Pharmacy Manual for detailed storage requirements and management instructions. 
7.2. 
Administration of Investigational Medicinal Product 
Patients will be instructed to ingest, placebo study drug 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 the 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.

Placebo Run-In Adherence to Study Medication 
At visits Week -1 (S3) and Week 0 (T1), designated clinical site staff will assess patient study 
drug compliance by counting the number of tablets that are returned as unused and by querying 
the patient with regards to daily intake.  If at the Week -1 (S3) visit the patient has not taken all 
doses of study drug(s) 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.  If at the T1 visit, the average study drug compliance from the placebo run-in period is 
<80%, or if the patient experiences an adverse event related to the run-in single blind placebo, 
the patient will not go onto randomization.   
Treatment Period Adherence to Study Medication and Procedures 
At each patient visit during the treatment period, designated clinical site staff will assess patient 
study drug compliance 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(s) 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.

STUDY PROCEDURES AND SCHEDULE OF ASSESSMENTS 
8.1. 
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 Institutional 
Review Board (IRB) or Independent Ethics Committee (IEC).   
8.2. 
Confirmation of Statin Intolerance (SI) 
The investigator is responsible for reviewing the patient’s available medical records and 
assessing the patient for SI.  This will include a review of statin use history.   
Both the patient and the investigator will sign a form confirming that that the patient is statin 
intolerant.  Within this form, the patient will acknowledge an understanding that they are at high 
risk for experiencing a heart attack or stroke and death and that using a statin would reduce that 
risk; however, they are not taking a statin because of intolerable side effects that started or 
increased during statin therapy and resolved or improved when statin therapy was discontinued.  
Within the same form, the investigator will confirm that the patient is unable to tolerate statin 
therapy (except possibly at very low average daily doses of atorvastatin <10 mg, fluvastatin 
<40 mg, lovastatin <20 mg, pravastatin <40 mg, pitavastatin <2 mg, rosuvastatin <5 mg, or 
simvastatin <10 mg) based on review of the medical history and discussion with the patient. 
Documentation of prior statin use will be based on patient recall and copies of relevant medical 
records and pharmacy records if readily available.  If investigator is unable to assess prior statin 
use due to poor patient recall and/or lack of relevant medical records, and if appropriate 
according to local medical practice, documentation of contact with primary care physician 
regarding prior statin use should be obtained.  At minimum, there will need to be documentation 
for the name of 2 statins and the dose of at least 1 statin attempted at low dose to ensure 
inclusion criteria is met.  All available prior statin use history will be recorded in the eCRF.  
Additionally, the basis for the investigator’s confirmation of the patient’s SI will be noted in the 
eCRF. 
8.3. 
Procedures and Schedule of Assessments 
The study will be conducted as outlined in the following sections.  Table 2 summarizes the study 
assessments at each study visit for patients enrolled in this study, followed by an overview of 
assessments by visit in Sections 8.3.1-8.3.8 .  Further details of the assessments are provided in 
the Study Operations Manual.

NOTE: For patients who withdraw from study drug treatment, but consent to be followed for safety assessments and return to clinic for these visits, 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 (AEs), physical 
examination (PE), vital signs, and electrocardiograms (ECGs).   
1 An optional fasting (minimum of 10 hours) TG assessment MAY be completed between Visits S1and S2 (prior to starting single-blind medication) if patient fails to meet TG 
criterion at Visit S1.  The repeat value will be used to determine eligibility.  
2 A recheck of blood pressure may be completed between Visits S1 and S2 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 (diastolic 
blood pressure [DBP] and/or systolic blood pressure [SBP]) do not meet exclusionary values.  Repeat labs may be completed between Visit S1 and Visit S2 to determine 
eligibility if the patient’s estimated glomerular filtration rate (eGFR), alanine aminotransferase (ALT), aspartate aminotransferase (AST) or other labs meet exclusion criteria 
levels.  If this optional lab is completed, the repeated value will be used to determine eligibility. 
3 All procedures will be completed for all patients at either 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 performed prior to any blood sample collection. 
6 Vital signs will include DBP, SBP, heart rate (HR) and will be collected prior to any blood sample collection.  Patient will rest for 5 minutes prior to assessments.

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 8.1), the patient will 
undergo the following assessments and procedures at Visit S1: 
1. Demographics 
2. Clinically relevant medical history  
3. Confirmation of statin intolerance and completion of confirmation forms 
4. Prior and concomitant medication review 
5. Review of all inclusion/exclusion criteria that can be assessed at this time 
6. Height (cm), and weight (kg)

• Serum pregnancy test in women of child-bearing potential only  
• FSH when required  
11. Contact IWRS to register the patient which includes entering whether the patient fits the 
definition of primary prevention or secondary prevention.  The IWRS system will be 
designed to ensure correct definitions of primary and secondary prevention are applied 
for purposes of stratification. 
Patients who meet all enrollment criteria that can be assessed at Visit S1 will be instructed to 
continue their allowed therapy(s) for lipid regulation and to maintain consistent diet and exercise 
patterns throughout the study.  Patients who fail to meet any entry criterion, other than those that 
can be repeated, 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). 
The screening period (between Visits S1 and S2) can be extended an additional 4 weeks if 
needed to adjust background therapy or other reasons.

Patients who withdraw from study drug prior to Week 24 (Visit T5) 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 Section 8.3). 
Patients who temporarily withdraw from study drug prior to Week 24 (Visit T5) for any reason 
may restart study drug providing that 1) the patient and the investigator are in agreement 
regarding this course of action, 2) the patient has been off of study drug for 4 weeks or less; and 
3) study drug can be started as soon as possible.  For cases where the patient has been off of 
study drug for more than 4 weeks, the investigator must contact the medical monitor for approval 
prior to restarting study drug.

Patients who do not wish 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 Section 8.3), or at a 
minimum at 24 weeks, to collect information on AEs, concomitant medications, 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 or treatment 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  
• 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. 
8.4.1. 
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.

Patients choosing to withdraw from the study early should be encouraged to return for all study 
scheduled clinic visits 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 24 
(Visit T5).  Subjects who are unwilling to return for clinic visits should return for an end of study 
visit (Visit T5). 
8.4.2. 
Patients Lost to Follow-Up 
A patient would be considered potentially lost to follow-up if he or she repeatedly fails to return 
for scheduled visits and is unable to be contacted by the study site.  Site personnel are expected 
to make diligent attempts to contact patients who fail to return for a scheduled visit or were 
otherwise unable to be followed up by the site.  Refer to the Retention Guide for additional 
details.  Vital status will be collected within legal and ethical boundaries during the study 
closeout period.  If vital status is determined, the patient will not be considered lost to follow-up. 
8.4.3. 
Discontinuation of Study Sites or the Study 
The Sponsor may suspend enrollment or discontinue a site at any time.  A written statement will 
be provided to the Investigator, the IRB or IEC, and regulatory authorities, if required.  
Possible reasons for site discontinuation 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. 
The Sponsor in consultation with the Executive Committee (EC) Chair will retain responsibility 
for discontinuation of the study.  The study will be discontinued if necessary for medical, safety, 
regulatory or other reasons consistent with applicable laws, regulations, and Good Clinical 
Practice (GCP). 
Discontinuation of the study may be based on a recommendation from the DMC.  The criteria 
that the DMC will follow to recommend early termination the study will be described in the 
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, based on medical judgement.

ASSESSMENT OF EFFICACY 
9.1. 
Efficacy Parameters 
After randomization, patients will return to clinic/or have phone contact with the clinic every 4 to 
12 weeks for a total of 24 weeks.  Clinical laboratory samples will be collected and analyzed for 
basic lipid parameters at each visit. 
9.2. 
Clinical Efficacy Laboratory Tests 
Blood draws for efficacy (not safety) must meet the criteria below.  If these criteria have not 
been met, efficacy blood samples will NOT be collected.  If these criteria can be met by 
rescheduling the clinic visit (within 3 days), efficacy 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), and 
• Patients will be in a seated position during the blood collection.  Clinical laboratory 
parameters and tests will include those listed in Table 3.  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 10.1.6. 
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.

ASSESSMENT OF SAFETY 
10.1. 
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.   
10.1.1. 
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.   
10.1.2. 
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.  At each clinic visit, 2 BP 
measurements will be collected at least 5 minutes apart.  
10.1.3. 
Weight, Height, and Body Mass Index 
Weight will be measured on a calibrated scale while fasted, 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

10.1.4. 
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 noted at Visit S2 will be recorded on the Medical History/Current 
Medical Conditions page of the eCRF.  Only changes from Visit S2 physical examination 
findings (or other unscheduled physical exams performed after informed consent but prior to 
randomization) 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 10.2.11.3.3. 
10.1.5. 
Electrocardiogram 
ECG collection will be preceded by a 10-minute rest time during which the patient will remain in 
the supine position.  ECGs will be collected prior to blood collection.  ECGs will be assessed 
using machine readings and physician review. 
10.1.5.1. 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.

instructions are provided in the Clinical Laboratory Manual.  A description of the sample 
collection, storage, and shipping are described in Section 10.1.6.3. 
10.1.6.3. Sample Collection, Storage, and Shipping 
Clinical laboratory and PK samples will be collected by appropriate clinical site personnel and 
then shipped according to a separate laboratory manual provided by the Central Laboratory.  
Samples will be processed by the Central Laboratory, and PK samples will be forwarded to the 
Bioanalytical Laboratory for analysis.   
10.1.6.4. 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.  Adverse events of special interest (AESI) 
monitored by clinical laboratories are discuss in the section on AESI (Section 10.2.11). 
10.1.6.5. Total Blood Volume of Clinical Laboratory 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, efficacy, biomarker assessment, and genetic 
analysis.  Total whole blood volume collected over the study duration is not to exceed 
approximately 250 mL for each patient. 
10.2. 
Adverse and Serious Adverse Events 
10.2.1. 
Definition of Adverse Event 
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 10.2.2) 
10.2.2. 
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 1002-046 
 
Amendment 1, 10 April 2017

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). 
10.2.3. 
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 S2 (Week -4), 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 10.2.7.4. 
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

Page 61 of 153 
 
• 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.  
10.2.4. 
Severity of Adverse Events 
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. 
10.2.5. 
Relationship  
Medical judgment should be used to determine the cause of the AE considering all relevant 
factors such as, but not limited to, the underlying study indication, coexisting disease, 
concomitant medication, relevant history, pattern of the AE, temporal relationship to the study 
medication, dechallenge or rechallenge.   
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.

Page 62 of 153 
 
• 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. 
• 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. 
10.2.6. 
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 8.3). 
10.2.7. 
Treatment-Emergent Adverse Event  
TEAE are defined as AEs that begin or worsen after the first dose of study drug. 
10.2.7.1. 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, nor will hospitalization for an elective or outpatient procedure scheduled or 
planned before signing of informed consent.  However, unexpected complications that occur 

Bempedoic Acid 
 
Esperion Therapeutics, Inc. 
Clinical Study Protocol 1002-046 
 
Amendment 1, 10 April 2017 
Confidential 
Page 63 of 153 
 
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.  
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 
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. 
10.2.7.2. 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 
10.2.7.3. 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 10.1.6.4. 
10.2.7.4. Reporting of Serious Adverse Events  
All SAEs, regardless of relationship to study drug, occurring from the time of informed consent 
until 30 days following last dose of study drug, must be reported by the Principal Investigator or 
designee to the Safety designee within 24 hours of the Principal Investigator or the clinical site 
becoming aware of the occurrence.  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 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 (drugsafety@esperion.com) or via fax 
(+1-734-887-3988).  
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 

Bempedoic Acid 
 
Esperion Therapeutics, Inc. 
Clinical Study Protocol 1002-046 
 
Amendment 1, 10 April 2017

Page 64 of 153 
 
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.  
10.2.7.5. 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 10.2.7.4.  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 
10.2.7.6. Reports of Pregnancy 
If a patient becomes pregnant during the study or within 30 days of 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 SAE; however, it must be reported to the 
Sponsor/SAE designee using the paper Pregnancy Report Form within the same timelines as an 
SAE.   

Bempedoic Acid 
 
Esperion Therapeutics, Inc. 
Clinical Study Protocol 1002-046 
 
Amendment 1, 10 April 2017 
Confidential 
Page 65 of 153 
 
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 Investigational Medicinal Product (IMP) 
immediately and complete the end of study evaluations. 
10.2.8. 
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 an SAE to the Sponsor/SAE 
designee 
10.2.9. 
Recording of Adverse Events and Serious Adverse Events 
Any AE that occurs following signing of the ICF through 30 days after completing the last study 
visit will be recorded on the AE eCRF.   
In order to avoid vague, ambiguous, or colloquial expressions, the AE should be recorded in 
standard medical terminology rather than the patient’s own words.  Whenever possible, the 
investigator should combine signs and symptoms that constitute a single disease entity or 
syndrome into a final diagnosis, if appropriate.  For example, fever, cough, and shortness of 
breath may be reported as pneumonia, if that is a reasonable diagnosis. 
Each AE is to be evaluated for duration, severity, seriousness, and causal relationship to the 
investigational drug.  The action taken and the outcome must also be recorded. 
SAEs that occur during the study or within 30 days completing the last study visit, whether or 
not related to study drug, must be immediately reported to the Sponsor/SAE designee.  The 
contact information for reporting of SAEs can be found on the SAE Reporting Form.  After the 
30-day reporting window, only SAEs assessed as related to study drug need to be reported. 
10.2.10. 
Follow-Up of Adverse Events and Serious Adverse Events 
All AEs occurring during the study are to be followed up in accordance with good medical 
practice until resolved; judged no longer clinically significant; or, if a chronic condition, until 
fully characterized through 30 days after the last dose of study drug.  Any SAEs must be 
followed until resolution or stabilization, or until lost to follow-up.  After the 30-day window, 
only treatment-related SAEs need to be reported.   
10.2.11. 
Adverse Events of Special Interest (AESI)

10.2.11.1. Potential Adverse Events Based on Findings in Bempedoic Acid Clinical Studies 
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), gastrointestinal (GI) disorders (nausea and 
diarrhea), and infections and infestations.  Overall, AEs were generally reported with similar 
incidence between those patients treated with bempedoic acid, 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 liver function test (LFT) abnormalities were considered mild to 
moderate and improved upon removal of the study drug.  Small group mean increases in uric 
acid and homocysteine, and decreases in hemoglobin have been observed, but in general, these 
shifts have not been associated with clinical symptoms.  Changes in vital signs, ECG, PE, and 
other physical findings presented no safety issues in any of the clinical studies.   
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 Section 8.3). 
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 

Bempedoic Acid

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 treatment with study drug.  The patient will return at 1-week 
intervals after withdrawing from study drug treatment for additional Hgb 
measurement until the level returns to baseline or reaches a satisfactory conclusion. 
• If the patient is withdrawn from study drug treatment, the patient should be asked to 
continue being followed for safety using the protocol-specified visit schedule (see 
Section 8.3). 
At any time, the investigator may choose to consult with a specialist to further evaluate the cause 
of the alteration in hemoglobin. 
10.2.11.2. Potential Adverse Events Based on Findings in Nonclinical Models 
10.2.11.3. Adverse Events Associated with Other Lipid-Lowering Therapies 
Adverse events that are currently monitored for all experimental lipid-lowering therapies and 
have been associated with previous lipid-lowering therapies and monitoring approach are listed 
below.

10.2.11.3.1. 
Cardiovascular Events 
The occurrence of clinical endpoints (major adverse cardiovascular events) 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, including those as adjudicated by the CEC, standard 
vital signs, and ECGs.   
10.2.11.3.2. 
Hepatic Function 
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).   
If at any time after randomization a patient experiences a new ALT and/or AST >3 × ULN, the 
patient will undergo repeat confirmatory 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 study drug treatment, but will be asked to continue to be followed for 
safety using the protocol-specified visit schedule (see Section 8.3) or more frequently 
if deemed appropriate 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 treatment with study drug, but 
will be asked to continue to be followed for safety using the protocol-specified visit 
schedule (see Section 8.3) or more frequently if deemed appropriate by the 
Investigator: 
− TB >2 × ULN (will be fractionated if >2 × ULN and for those with Gilbert’s 
Disease 2 × ULN conjugated (direct) bilirubin will be evaluated) 
− 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 
10.2.11.3.3. 
Muscle-Related Events 
Muscle:  Muscle events have been associated with statins 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 and will be recorded 
on eCRFs, including a muscle-specific AE eCRF.  More detailed investigation will occur if 
laboratory CK results exceed 5 × ULN.   
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 study drug 
− 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 study drug once CK returns to baseline 
levels 
− If no alternative explanation exists, consideration should be given to withdrawing 
the patient from study drug 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.  For CK elevations >10 × ULN, 
hold study drug treatment until the repeat value returns, is evaluated, and is 
<10 × ULN before restarting study medication. 
− In all cases, evaluate the signs/symptoms and laboratory evaluations as outlined 
above. 
• If the patient is withdrawn from study drug treatment, the patient should be asked to 
continue being followed for safety using the protocol-specified visit schedule (see 
Section 8.3). 
10.2.11.3.4. 
Diabetes and Hyperglycemia 
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.   
10.2.11.3.5. 
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.  Patients will be monitored beyond the conclusion of the study if necessary 
to follow abnormal renal laboratory values until resolution or stabilization.   
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 study drug treatment but will be asked to continue to be followed for safety 
using the protocol-specified visit schedule (see Section 8.3) 
10.2.11.3.6. 
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 (Food and Drug Administration 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. 
10.2.12. 
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 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 study drug treatment and will 
be asked to continue to be followed for safety using the protocol-specified visit 
schedule (see Section 8.3). 
• Please see the Clinical Laboratory Manual for sample collection and instructions. 
10.3. 
Data Monitoring Committee (DMC) 
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. 
10.4. 
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

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.

STATISTICS 
11.1. 
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 relation to 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. 
11.2. 
Sample Size 
The primary efficacy endpoint for this study is the percent change from baseline to Week 12 in 
LDL-C.   
 
11.3. 
Analysis Populations 
The Full Analysis Set (FAS), used for all of the efficacy 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 the treatment they 
actually received. 
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.   
11.4. 
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. 
11.5. 
Primary Endpoint Analysis 
The primary efficacy endpoint is the percent change from baseline to Week 12 in LDL-C.  
Baseline is defined as the mean of the values from Week -1 (Visit S3) and predose 
Day 1/Week 0 (Visit T1).   
The primary efficacy endpoint will be analyzed using analysis of covariance (ANCOVA), with 
treatment group and patient type (primary prevention; secondary prevention) as factors and 

Bempedoic Acid

baseline LDL-C as a covariate.  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 account 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.  
Patients with missing LDL-C data at Week 12 who are no longer taking study treatment can be 
assumed no longer to be benefitting from study medication, and their missing value(s) can be 
assumed to be similar to those from placebo patients.  In this instance, it is reasonable to impute 
LDL-C values in a model including placebo patients’ data only.  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.  Details for the 
PMM will be described in the SAP.  
To account for uncertainty, missing values will be imputed using multiple imputation. Imputed 
datasets will be analyzed using an ANCOVA model with the treatment and patient type (primary 
prevention; secondary prevention) 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. 
11.6. 
Secondary and Tertiary Endpoint Analysis 
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.

Amendment 1, 10 April 2017

Page 75 of 153 
 
For the remaining secondary efficacy endpoints and the tertiary efficacy endpoints, a 
significance level of 0.05 will be used; given the large number of remaining endpoints, the 
p-values for those endpoints will be considered descriptive. 
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 and patient type 
(primary prevention; secondary prevention) as factors and the relevant baseline as a covariate.   
Baseline for 
non-HDL-C,
 and TC is defined as the mean of the values from 
Week -1 (Visit S3) and predose Day 1/Week 0 (Visit T1).  Baseline for apoB and hs-CRP is 
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 severe 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. 
Finally, the number and percent of patients in each treatment group requiring additional (post-
randomization) TG-lowering therapy will be summarized.  The medications will be summarized 
by treatment group.  
11.7. 
Safety Analysis 
The summarization of AEs will include TEAEs, defined as any unfavorable and unintended sign, 
symptom, or disease temporally associated with the use of the investigational product, whether 
or not related to the product.  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 post baseline 
time point. 
Hepatic Safety 
For liver-associated enzymes and TB, the number and percent of patients with abnormal values 
for ALT, AST, and TB will be summarized.  Hy’s law criteria (≥3 × ULN for either ALT or 
AST, with accompanying TB >2 × ULN (conjugated [direct] if Gilbert’s Disease) in the absence

listed separately. 
Musculoskeletal Safety 
AEs of muscle-related symptoms will be summarized by treatment group.  In addition, the 
number and percent of patients with abnormal CK values will be summarized.   
Diabetes/Glycemia 
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. 
Renal Safety 
Baseline eGFR and values of CK will be summarized by treatment group and by baseline eGFR 
categories.  Shift tables of eGFR category from baseline over the study, will be provided by 
treatment group.  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 treatment group. 
Clinical endpoints 
Clinical endpoints will be monitored and adjudicated by an independent blinded expert CEC for 
this study and other ongoing studies the bempedoic acid program.  Adjudicated clinical 
endpoints will be summarized by event type and treatment group.  Additional details regarding 
clinical endpoints and clinical endpoint definitions will be included in CEC charter.   
11.8. 
Pharmacokinetics 
Three plasma PK samples for analysis will be collected.  Plasma concentrations of bempedoic 
acid and optionally, one or more of its metabolites, will be determined in patients who are 
receiving bempedoic acid.  All patients, site personnel, and study personnel will remain blinded 
to treatment assignment throughout the duration of the study.  Personnel performing the 
bioanalytical analysis of bempedoic acid concentrations will be unblinded in order to assay the 
appropriate samples during the study.  Plasma concentrations of bempedoic acid and any 
measured metabolite will be included in the listings, but population PK analysis will be reported 
separately will be descriptive by time point. 
11.9. 
Interim Analysis and Data Monitoring Committee 
There are no planned interim analyses for this study.  An independent DMC will review 
accumulating unblinded safety data from this study and other ongoing studies of bempedoic acid.  
Additional details regarding the DMC will be included in the DMC Charter.

DATA HANDLING AND RECORDKEEPING 
15.1. 
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. 
15.2. 
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. 
15.3. 
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 hand-written 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 study drug treatment, but consent to be followed for safety assessments and return to 
clinic for these visits, 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 (AEs), physical examination (PE), vital signs, and 
electrocardiograms (ECGs). 
1 An optional fasting (minimum of 10 hours) TG assessment MAY be completed between Visit S1 and Visit S2 (prior to starting 
single-blind medication) if patient fails to meet TG entry criterion at Visit S1.  If this optional TG is completed, the repeat value 
will be used to determine eligibility.  
2 A recheck of blood pressure may be completed between Visits S1 and S2 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 (diastolic blood pressure [DBP] 
and/or systolic blood pressure [SBP]) do not meet exclusionary values.  Repeat labs may be completed at Visit S2 to determine 
eligibility if the patient’s estimated glomerular filtration rate (eGFR), alanine aminotransferase (ALT), aspartate 
aminotransferase (AST) or other labs meet exclusion criteria levels.  If this optional lab is completed, the repeated value will be 
used to determine eligibility. 
3 All procedures will be completed for all patients at either 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 performed prior to any blood sample collection. 
6 Vital signs will include DBP, SBP, heart rate (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-ABVivi. 
8 Pregnancy test completed in women of child-bearing potential only. FSH in naturally postmenopausal women ≥1 year without 
menses and <55 years; 
9 Urine pregnancy test completed in women of child-bearing potential only just prior to randomization.  
10 Clinical safety labs include hematology, blood chemistry, and urinalysis at all visits.  A coagulation panel will be completed for 
all patients at Week -5 (Visit S1).  A coagulation panel will be completed only for patients on anti-coagulant therapy at Day 1 
(Visit T1) and 3 to 5 days later.  For these visits, the sample may be analyzed at either the central or a local lab.  Please refer to 
laboratory manual for detailed schedule of tests. 
11 Basic fasting (minimum of 10 hours) lipids include total cholesterol, calculated low-density lipoprotein cholesterol (LDL-C), 
high-density lipoprotein cholesterol (HDL-C), non-HDL-C, and triglycerides.  
12 Diet and exercise counseling per local and/or regional guidelines for the management of hyperlipidemia. 
13 Interactive web response system (IWRS) contact at either an early withdrawal or an EOS visit to register study discontinuation 
visit date.

Patient Identification (Please Print or Type) 
Name: 
 
Initials: 
 
Screening Number: 
 
 
Patient  
My doctor has recommended that I take a medication (called a statin) to reduce the bad 
cholesterol (fats) in my blood.  My doctor has told me that a statin would reduce my risk of a 
heart attack or stroke and the risk of death.  However, I am not taking a statin (or I am taking a 
statin only at a very low dose) because of side effects.  These side effects began or became 
worse when I was taking the statin and then went away or improved when I stopped taking it or 
decreased the dose.  I can’t tolerate these medications (called statins) even though I know they 
would reduce my risk of a heart attack or stroke or death.  
 
 
Date 
Signature of Patient 
 
Principal Investigator   
For the purposes of the 1002-046 clinical study, in my opinion, this patient is unable to tolerate 
statin therapy (except possibly at very low average daily doses of atorvastatin <10 mg, 
fluvastatin <40 mg, lovastatin <20 mg, pravastatin <40 mg, pitavastatin <2 mg, rosuvastatin 
<5 mg or simvastatin <10 mg) based on my review of the medical and medication histories and 
discussion with the patient.

• Under inclusion criteria 
− Added topical method to 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.  In addition, specified the period that contraception should be 
followed.  This amendment is to maintain consistency across protocols and is not 
based on any new data with bempedoic acid. 
− Added expanded definition of ‘true abstinence. 
− Added an 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. 
• Under exclusion criteria 
− Revised exclusionary blood pressure to systolic blood pressure (SBP) 
≥160 mmHg and diastolic blood pressure (DBP) ≥100 mmHg based on a request 
by Health Canada.  Instructions regarding repeat measures of blood pressure were 
further clarified.   
− Shortened the window that obesity medications should not be initiated or changed 
before randomization from 3 months to 4 weeks. 
− Clarified language around PCSK9 inhibitor use prior to screening. 
− Added an exclusion for women who are pregnant, breastfeeding or intending to 
become pregnant within 30 days after the last dose of study drug.   
− Based on the extremely long half-lives of experimental siRNA inhibitors, eg, 
Inclisiran, excluded patients who have enrolled in a study of an experimental 
siRNA inhibitor of PCSK9. 
− Excluded gemfibrozil in patients taking very low dose statins per the co-
administration prescribing instructions.   
• 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. 
• Updated text pertaining to bempedoic acid mechanism of action based on new 
information.

• Removed manufacturing contact details from the protocol and indicated the details 
will be described in the pharmacy manual. 
• Updated the sections on prohibited and allowed medications to reflect the following: 
− Added inhaled steroids to allowable stable systemic corticosteroids at screening.  
− Noted that fibrates could not be used within 6 weeks prior to screening versus 
within 4 weeks for other hypertriglyceridemia medications. 
• Specified that documentation for the name of two statins and dose of at least one 
statin attempted at a low dose is required.   
• Added a section on overdose management based on a request from Health Canada. 
• Based on a request from the FDA, the monitoring and management of CK values for 
asymptomatic patients was modified.   
• Updated text around reporting of Adverse Events and Pregnancies. 
• 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 
• Revised statistical sections regarding 
− methods for imputation of missing data for primary, secondary, and tertiary 
endpoints. 
− how ANCOVA model will be applied to primary, secondary, and tertiary 
endpoints. 
• Made administrative changes throughout the protocol where required to correct 
inconsistencies, add clarification, or correct errors.

MECHANISM OF ACTION REVISION 
Location: 
Section 4.2.1, Mechanism of Action 
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 enters 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.

Original Text: 
This is a Phase 3, randomized, double-blind, placebo-controlled, parallel group multicenter study 
that will be conducted at approximately 71 clinical sites in North America.  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.  Eligible 
patients will return to the clinical site at Week -4 (Visit S2) to initiate administration of single-
blind (patient only) placebo study drug.  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.

Placebo Run-In Adherence to Study Medication 
At visits Week -1 (S1) and Week 0 (T1), designated clinical site staff will assess patient study 
drug compliance by counting the number of tablets that are returned as unused and by querying 
the patient with regards to daily intake.  If at the Week -1 (S1) visit the patient has not taken all 
doses of study drug(s) 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.  If at the T1 visit, the average study drug compliance from the placebo run-in period is 
<80%, or if the patient experiences an adverse event related to the run-in single blind placebo,

NOTE: For patients who withdraw from study drug treatment, but consent to be followed for safety assessments and return to clinic for these visits, 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 (AEs), physical 
examination (PE), vital signs, and electrocardiograms (ECGs).  For patients who withdraw from study drug 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 T5 will be considered the End of Study (EOS)/Early Withdrawal from study and no further visits will be scheduled. 
1 An optional basic fasting (minimum of 10 hours) lipid MAY be completed at Visit S2 (prior to starting single-blind medication) if patient fails to meet lipid entry criterion at 
Visit S1,The mean of the first value and the repeat value will be used to determine eligibility.

2 A recheck of blood pressure may be completed at Visit S2 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 (diastolic blood 
pressure [DBP] and/or systolic blood pressure [SBP]) do not meet exclusionary values.  Repeat labs may be completed at Visit S2 to determine eligibility if the patient’s 
estimated glomerular filtration rate (eGFR), alanine aminotransferase (ALT), aspartate aminotransferase (AST) or other labs meet exclusion criteria levels.  If this optional lab is 
completed, the repeated value will be used to determine eligibility. 
3 All procedures will be completed for all patients at either 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 performed prior to any blood sample collection. 
6 Vital signs will include DBP, SBP, heart rate (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-ABVivi. 
8 Pregnancy test completed in women of child-bearing potential only. FSH in naturally postmenopausal women ≥1 year without menses and <55 years; 
9 Clinical safety labs include hematology, blood chemistry, and urinalysis at all visits.  A coagulation panel will be completed for all patients at Week -5 (Visit S1).  A coagulation 
panel will be completed only for patients on vitamin K antagonists at Day 1 (Visit T1) and 3 to 5 days later.  Please refer to laboratory manual for detailed schedule of tests. 
10Basic fasting (minimum of 10 hours) lipids include total cholesterol, calculated low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), non-
HDL-C, and triglycerides.  Repeat within 1 week if exceed protocol-specified criteria.

Original Text: 
Prior to scheduling Visit T1, review the screening clinical results to determine whether the 
patient continues to meet lab eligibility criteria.  At Visit T1, determine whether the patient was 
adherent with placebo treatment during the run-in period (average of ≥80% adherence required) 
and had no issues with tolerability of run-in period study medication.  Patients with intolerable 
side effects, including but not limited to muscular skeletal pain, will be run-in failures. 
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 all entry criteria 
after initiation of single-blind placebo run-in are considered to be run-in failures and will not be 
randomized.  
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.

PRIMARY AND SECONDARY ENDPOINT AND SAFETY 
ANALYSES

Section 2, Synopsis; Section 11.5, Primary Endpoint Analysis; Section 11.6, Secondary and 
Tertiary Endpoint Analysis; Section 11.7, Safety Analysis 
Original Text: 
11.5 
Primary Endpoint Analysis 
The primary efficacy endpoint is the percent change from baseline to Week 12 in LDL-C.  
Baseline is defined as the mean of the values from Week -1 (Visit S3) and predose 
Day 1/Week 0 (Visit T1).   
The primary efficacy endpoint will be analyzed using analysis of covariance (ANCOVA), with 
treatment group and patient type (primary prevention; secondary prevention) as factors and 
baseline LDL-C as a covariate.  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 confirmatory.  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 an ANCOVA model with the treatment and 
patient type (primary prevention; secondary prevention) 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% confidence 
interval (CI) and associated p-value.

11.6 
Secondary and Tertiary Endpoint Analysis 
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: 
6. Test the primary efficacy endpoint: percent change from baseline to Week 12 in LDL-C  
7. Test the percent change from baseline to Week 24 in LDL-C 
8. Test the percent change from baseline to Week 12 in non-HDL-C 
9. Test the percent change from baseline to Week 12 in TC 
10. Test the percent change from baseline to Week 12 in apoB 
11. 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. 
For the remaining secondary efficacy endpoints and the tertiary efficacy endpoints, a 
significance level of 0.05 will be used; given the large number of remaining endpoints, the 
p-values for those endpoints will be considered descriptive. 
Percent change from baseline to Week 24 in LDL-C; change from baseline to Weeks 12 and 24 
in LDL-C; percent change from baseline to Weeks 12
in
non-HDL-C,
 and 
TC; and percent change from baseline to Weeks 12
in apoB and hs-CRP will each be 
analyzed using ANCOVA with treatment group and patient type (primary prevention; secondary 
prevention) as factors and the relevant baseline as a covariate.  Baseline for
 non-
HDL-C,
 and TC is defined as the mean of the values from Week -1 (Visit S3) and predose 
Day 1/Week 0 (Visit T1).  Baseline for apoB and hs-CRP is 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,
 non-
HDL-C, TC,
apoB, and hs-CRP; change from baseline in LDL-C; to Week 12 and 24, 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. 
Finally, the number and percent of patients in each treatment group requiring additional (post-
randomization) TG-lowering therapy will be summarized.  The medications will be summarized 
by treatment group.

Safety Analysis 
No statistical analyses will be performed on any of the safety data in this study.   
The summarization of AEs will include TEAEs, defined as any unfavorable and unintended sign, 
symptom, or disease temporally associated with the use of the investigational product, whether 
or not related to the product.  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.

The details of the ANCOVA model and options to account 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.  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 confirmatory.  The A pattern mixture model 
(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 to be benefitting from study medication, and 
their missing value(s) can be assumed to be returning toward their baseline value similar to those 
from placebo patients.  In this instance, it is reasonable to impute LDL-C values based on the 
patients’ baseline value. in a model including placebo patients’ data only.  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.  Details 
for the PMM will be described in the SAP.  
To account for uncertainty, missing values will be imputed using multiple imputation.  Imputed

significance level of 0.05 will be used; given the large number of remaining endpoints, the 
p-values for those endpoints will be considered descriptive. 
In general, change or percent change in lipid parameters at a given time point will be analyzed

NOTE: For patients who withdraw from study drug treatment, but consent to be followed for safety assessments and return to 
clinic for these visits, 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 (AEs), physical examination (PE), vital signs, and 
electrocardiograms (ECGs).  For patients who withdraw from study drug 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 T5 will be considered the End of Study (EOS)/Early Withdrawal from study and no further visits will be 
scheduled. 
1 An optional basic fasting (minimum of 10 hours) lipid MAY be completed at Visit S2 (prior to starting single-blind medication) 
if patient fails to meet lipid entry criterion at Visit S1.  If this optional basic fasting lipid is completed, the mean of the first value 
and the repeat value will be used to determine eligibility.  
2 A recheck of blood pressure may be completed at Visit S2 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 (diastolic blood pressure [DBP] and/or systolic 
blood pressure [SBP]) do not meet exclusionary values.  Repeat labs may be completed at Visit S2 to determine eligibility if the 
patient’s estimated glomerular filtration rate (eGFR), alanine aminotransferase (ALT), aspartate aminotransferase (AST) or other 
labs meet exclusion criteria levels.  If this optional lab is completed, the repeated value will be used to determine eligibility. 
3 All procedures will be completed for all patients at either 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 performed prior to any blood sample collection. 
6 Vital signs will include DBP, SBP, heart rate (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-ABVivi. 
8 Pregnancy test completed in women of child-bearing potential only. FSH in naturally postmenopausal women ≥1 year without 
menses and <55 years; 
9 Urine pregnancy test completed in women of child-bearing potential only just prior to randomization.  
10 Clinical safety labs include hematology, blood chemistry, and urinalysis at all visits.  A coagulation panel will be completed for 
all patients at Week -5 (Visit S1).  A coagulation panel will be completed only for patients on anti-coagulant therapy at Day 1 
(Visit T1) and 3 to 5 days later.  Please refer to laboratory manual for detailed schedule of tests. 
11 Basic fasting (minimum of 10 hours) lipids include total cholesterol, calculated low-density lipoprotein cholesterol (LDL-C), 
high-density lipoprotein cholesterol (HDL-C), non-HDL-C, and triglycerides.  Repeat within 1 week if exceed protocol-specified 
criteria. 
12 Diet and exercise counseling per local and/or regional guidelines for the management of hyperlipidemia. 
13 Interactive web response system (IWRS) contact at either an early withdrawal or an EOS visit to register study discontinuation 
visit date.

NOTE: For patients who withdraw from study drug treatment, but consent to be followed for safety assessments and return to 
clinic for these visits, 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 (AEs), physical examination (PE), vital signs, and 
electrocardiograms (ECGs).  For patients who withdraw from study drug 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 T5 will be considered the End of Study (EOS)/Early Withdrawal from study and no further visits will be 
scheduled. 
1 An optional basic fasting (minimum of 10 hours) lipid TG assessment MAY be completed between Visit S1 and at Visit S2 
(prior to starting single-blind medication) if patient fails to meet lipid TG entry criterion at Visit S1.  If this optional basic fasting 
lipid TG is completed, the mean of the first value and the repeat value will be used to determine eligibility.  
2 A recheck of blood pressure may be completed between Visit S1 and at Visit S2 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 (diastolic blood pressure 
[DBP] and/or systolic blood pressure [SBP]) do not meet exclusionary values.  Repeat labs may be completed at Visit S2 to 
determine eligibility if the patient’s estimated glomerular filtration rate (eGFR), alanine aminotransferase (ALT), aspartate 
aminotransferase (AST) or other labs meet exclusion criteria levels.  If this optional lab is completed, the repeated value will be 
used to determine eligibility. 
3 All procedures will be completed for all patients at either 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 performed prior to any blood sample collection. 
6 Vital signs will include DBP, SBP, heart rate (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-ABVivi. 
8 Pregnancy test completed in women of child-bearing potential only. FSH in naturally postmenopausal women ≥1 year without 
menses and <55 years; 
9 Urine pregnancy test completed in women of child-bearing potential only just prior to randomization.  
10 Clinical safety labs include hematology, blood chemistry, and urinalysis at all visits.  A coagulation panel will be completed for 
all patients at Week -5 (Visit S1).  A coagulation panel will be completed only for patients on anti-coagulant therapy at Day 1 
(Visit T1) and 3 to 5 days later.  For these visits, the sample may be analyzed at either the central or a local lab.  Please refer to 
laboratory manual for detailed schedule of tests. 
11 Basic fasting (minimum of 10 hours) lipids include total cholesterol, calculated low-density lipoprotein cholesterol (LDL-C), 
high-density lipoprotein cholesterol (HDL-C), non-HDL-C, and triglycerides.  Repeat within 1 week if exceed protocol-specified 
criteria. 
12 Diet and exercise counseling per local and/or regional guidelines for the management of hyperlipidemia. 
13 Interactive web response system (IWRS) contact at either an early withdrawal or an EOS visit to register study discontinuation 
visit date.
