Other biomarker and PK samples: 
Pharmacokinetics 
Three pharmacokinetic (PK) samples will be collected (see lab manual).  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.

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 if the safety clinical laboratory results are 3 times or more than the ULN.  
Further details on occurrence and monitoring are available in the Investigator’s Brochure (IB) and 
protocol.  
Statistical methods: 
Sample Size 
The planned total sample size for this study is 52 with 26 patients in the bempedoic acid 180 mg group 
and 26 in the placebo group.  This sample size is expected to 
 
  
Analysis Populations 
The Full Analysis Set (FAS), used for all of the efficacy analyses, is defined as all randomized patients 
with a baseline lipid value, at least 1 postbaseline lipid value, and having taken their study drug within 
2 days of the lipid measurement.  The FAS is also known as the modified intention-to-treat (mITT) set of 
patients.  Patients in the FAS will be included in their randomized treatment group, regardless of the 
treatment they actually received.  Other subsets of the FAS will be considered to evaluate primary and 
secondary endpoints as sensitivity analyses and the details will be described in the statistical analysis plan 
(SAP). 
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 Month 2 in LDL-C.  The primary 
efficacy endpoint will be analyzed using analysis of covariance (ANCOVA), with treatment group as a 
factor and baseline LDL-C as a covariate.  The details of the ANCOVA model and options to correct for 
unequal variances will be described in the SAP.  Baseline LDL-C is defined as the average of S4 and 
Day 1 values, if only 1 value is available, then that single value will be used as baseline.  The ANCOVA 
will be performed using the FAS, with patients included in their randomized treatment group regardless 
of the treatment they actually received.  Patients who are missing their Month 2 LDL-C will have their 
Month 2 value imputed by last observation carried forward (LOCF).  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 Exploratory Efficacy Endpoints 
Secondary endpoints based on lipid parameters will be analyzed in the similar fashion as for the primary 
endpoint. 
Safety Analyses 
Descriptive summary will be provided for the safety data in this study.   
The subject incidence of all treatment-emergent AEs (TEAE), SAEs, related AEs, AEs leading to 
withdrawal of study drug and/or study, fatal AEs, and AEs of special interest (AESI) will be tabulated by 
system organ class (SOC) and preferred term in descending order of frequency and by treatment group.

Clinical safety laboratories, including hematology, blood chemistry, HbA1C, glucose, and urinalysis; PE 
findings; vital signs; and weight will be summarized by the value and by change from baseline in the 
value (where appropriate) at each postbaseline time point. 
Hepatic Safety 
For liver-associated enzymes and TB, the number and percent of patients with abnormal values for ALT, 
AST, and TB will be summarized.  All liver-associated laboratory abnormalities will be assessed for Hy’s 
Law criteria (≥3 × ULN for either ALT or AST, with accompanying TB >2 × ULN in the absence of 
other known causes). 
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.  Finally, muscle-related AEs will be 
summarized by treatment group and by baseline eGFR category. 
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.   
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.

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 (CV) risk unable to meet their treatment goals with currently 
available lipid-lowering therapies. 
Proprotein convertase subtilisin kexin type 9 (PCSK9) reduces LDL receptor recycling to the 
hepatic surface, thereby limiting removal of LDL particles from the circulation.  Monoclonal 
antibodies neutralize PCSK9 and reduce LDL-C levels when administered alone or in 
combination with other background therapies.   
Elevated LDL-C is a major modifiable risk factor for the development of atherosclerosis and 
atherosclerotic cardiovascular diseases (ASCVD) (Sharrett 2001).  Despite aggressive 
interventional and pharmacologic therapies, CV disease is the number 1 cause of death globally 
(WHO 2015).  An estimated 17.5 million people died from CV diseases in 2012, representing 
31% of all global deaths. Of these deaths, an estimated 7.4 million were due to coronary heart 
disease (CHD) and 6.7 million were due to stroke (WHO 2015). Cardiovascular disease remains 
the leading cause of death among Europeans, Americans, and around the world.  The Global 
Burden of Disease study estimated that 29.6% of all deaths worldwide (approximately 
15.6 million deaths) were caused by CV disease in 2010, more than all communicable, maternal, 
neonatal and nutritional disorders combined, and double the number of deaths caused by cancers 
(Nichols 2014).  In the United States (US), based on 2011 death rate data, more than 
2150 Americans die from CV diseases daily, an average of 1 death every 40 seconds.  
Approximately 155,000 Americans dying from CV disease are less than 65 years of age.  In 
2011, 34% of deaths due to CV disease occurred prior to the age of 75 years, less than the 
current 78.7-year average life expectancy (Mozffarian 2015). As such new therapies to combat 
this global public health problem are needed. 
Global guidelines recommend lowering of LDL-C to levels below 100 mg/dL and often under 
70 mg/dL (Jacobson 2014) or reduction of ≥50% (Stone 2013).  In order to reach these goals, 
lipid-lowering therapies are often taken in combination.  The combination of bempedoic acid and 
a PCSK9 inhibitor (PCSK9i) may offer an additional treatment option in the future for 
physicians. 
4.2. 
Background on Bempedoic Acid 
4.2.1. 
Mechanism of Action 
Bempedoic acid is a first-in-class small molecule inhibitor of ACL, an enzyme upstream of 
HMG-CoA in the cholesterol biosynthesis pathway.  Bempedoic acid is a prodrug that requires 
activation in liver to ETC-1002-co-enzyme A (ETC-1002-CoA), which mediates competitive

inhibition of ACL.  Inhibition of ACL by ETC-1002-CoA decreases cholesterol synthesis in liver 
leading to increased 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 it does not inhibit cholesterol 
synthesis in skeletal muscle.  In addition to preliminary data suggesting that only minor amounts 
of bempedoic acid enter skeletal muscle (<5% of systemic exposure), skeletal muscle does not 
express the enzyme required to activate bempedoic acid to ETC-1002-CoA and inhibit ACL.  
Therefore, bempedoic acid is not anticipated to mediate the adverse effects associated with 
inhibition of biological intermediates within the cholesterol biosynthesis pathway in skeletal 
muscle.  The long-term safety of bempedoic acid and its metabolites regarding human skeletal 
muscle is not yet established.

Background Therapy 
Bempedoic acid in this study is currently being evaluated as an add-on to PCSK9i therapy.  
4.2.6. 
Risk Benefit Summary 
To date, the nonclinical and clinical data indicate that bempedoic acid has a favorable risk-
benefit profile.  The ability of bempedoic acid to achieve clinically meaningful LDL-C-lowering 
responses while demonstrating a favorable tolerability profile in a variety of patient populations 
supports continued development of bempedoic acid, an oral ACL inhibitor, in Phase 3 studies. 
Please refer to the most recent IB for additional information regarding previous human 
experience.

INVESTIGATIONAL PLAN 
6.1. 
Overall Study Design 
This is a Phase 2, randomized, double-blind, placebo-controlled, parallel group multicenter study 
that will be conducted at approximately 20 clinical sites in North America.  Screening 
Month -4.5 (Visit S1) will occur approximately 18 weeks prior to randomization.  After 
providing informed consent at Visit S1, patients will stop all background lipid-lowering therapy 
and lipid-modifying nutritional supplements, if applicable.  All patients will return to the clinic 
on Month -3 (Visit S2).  During this visit, patients with an LDL-C value ≥160 mg/dL (via central 
or local lab) and triglycerides <500 mg/dL (via central or local lab) will initiate PCSK9 
background therapy (Repatha 420 mg once montly [QM]).  Sites that do not use a local lab may 
need to bring patients back for another visit to administer PCSK9 background therapy, as a 
qualifying LDL value is required prior to initiating the 3-month PCSK9i run-in period.  No other 
background lipid-modifying therapy except study provided PCSK9i will be permitted during the 
trial.  After 1 month (at least 30 ± 3 days), patients will return to the clinic for Month -2 
(Visit S3) followed by Month -1 (Visit S4) 30 ± 3 days later.  During these visits, Repatha will 
be administered, labs will be collected, and safety assessed.  At Visit S4, LDL-C will be checked 
a second time prior to randomization.  Patients with an LDL-C ≥70 mg/dL (via central lab only) 
at this visit will qualify for randomization.  Patients with LDL-C <70 mg/dL at Visit S4 will be 
screen failed and no further PCSK9i therapy will be administered.  Day 1 should occur 30 days ± 
3 days after Visit S4, once LDL-C eligibility is established.  On Day 1, qualified patients will be 
randomized 1:1 to bempedoic acid 180 mg/day (n = 26) or matching placebo (n = 26).  
Randomized patients will return for clinic visits at Month 1 (Visit T2) and Month 2 (Visit T3).  
Both study drug and PCSK9i doses will be administered on site during clinic visits after all 
procedures have been completed.   
An independent expert Data Monitoring Committee (DMC) will formally review accumulating 
unblinded safety and efficacy data across the bempedoic acid program.

6.6.1. 
Screening and 1 Month PCSK9i Run-in Period  
Screening will occur approximately 18 weeks prior to Day 1 (Visit T1).  Eligible patients will 
return to the clinical site at Month -3 (Visit S2).  During this visit, patients with an LDL-C value 
≥160 mg/dL (via central or local lab) and triglycerides <500 mg/dL (via central or local lab) will 
initiate study-provided PCSK9i background therapy (Repatha 420 mg QM).  No other 
background lipid-modifying therapy except study provided PCSK9i will be permitted during the 
trial.  
Patients who are deemed not eligible for randomization at any point during screening will be 
notified by clinical site personnel regarding their eligibility status and considered screen failures.  
As necessary, for reasons of safety if a patient begins the run-in period but screen fails prior to 
randomization, the patient may be asked to return to the clinical site for further evaluation and 
follow-up of AEs. 
6.6.2. 
Randomization and Treatment Period 
Patients who satisfy all entry criteria, complete the 1.5-month screening period and 3-month 
PCSK9i run-in period, and have an LDL-C ≥70 mg/dL at S4 will be randomized.  
Randomization numbers will be assigned via IWRS on Day 1 (Visit T1).  Patients will be 
randomized in a ratio of 1:1 to receive 1 of the following 2 treatments in a double-blind fashion 
in addition to monthly PCSK9i background therapy: 
• Bempedoic acid 180-mg tablet 
• Matching placebo tablet

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

8.2.1. 
Prohibited Lipid-Regulating Medications and Dietary Supplements 
• Patients will be required to stop taking all prescription or nonprescription drugs or 
dietary supplements taken for the purpose of lipid regulation at Month -4.5.  With the 
exception of the study provided PCSK9i (Repatha 420 mg QM), no other lipid-
modifying therapies or supplements will be permitted. 
8.2.2. 
Allowable Medications 
• Hormone replacement (if stable 6 weeks prior to Month -4.5) 
• Thyroid replacement (if stable 6 weeks prior to Month -4.5) 
• Obesity medication (if stable 3 months prior to Month -4.5) 
8.3. 
Blinding 
Patients who satisfy all entry criteria during the screening phase and complete the PCSK9i run-in 
period will be randomized to a treatment group at Day 1 (Visit T1).  The Investigator or designee 
will contact IWRS at this visit to randomize the patient into the study.  The IWRS will determine 
the randomized treatment assignment number and the appropriate study drug container via 
medication identification numbers (MED ID).  A patient is considered to be randomized when 
they have been assigned a MED ID number by IWRS. 
After patients have been randomized, study drug, which is assigned by the IWRS, will be 
administered in a double-blind fashion.  The Sponsor, all clinical site personnel (Investigator, 
pharmacist, etc), and other vendor personnel will be blinded to the treatment group for each 
patient.  Patients will also be blinded to the treatment they receive.  Unblinded User(s) will be 
designated for each clinical site and at the sponsor (or designee) as needed.  Unblinded 
individuals will be provided IWRS access allowing them the ability to perform emergency 
unblinding of treatment for an individual patient.  An affirmative entry of the user’s login details 
will be required before the treatment group is displayed.  Unblinding at the clinical site for any 
other reason will be considered a protocol deviation.  Unblinded treatments for patients will 
NOT automatically discontinue the patient from the study.  To discontinue the patient from the 
study, the appropriate clinical site personnel will need to register the ‘discontinuation’ visit 
separately.  
Blinding of treatment must be maintained for all patients unless, in the opinion of the 
Investigator, the safety of the patient may be at risk.  Only under the rarest of circumstances 
should the Investigator consider breaking the blind and only when medical/supportive care 
cannot be provided without determining if the patient is receiving active drug treatment.  In the 
event that the blind needs to be broken prior to completion of the study, the Investigator should 
contact the appropriate Medical Monitor by telephone.  If the blind must be broken prior to 
consultation with the Medical Monitor, contact must be made within 24 hours of breaking the 
blind.  At the initiation of the study, the clinical site will be instructed on procedures for breaking 
the blind via the IWRS.  In all cases of breaking the blind, the Investigator must document in the 
patient’s medical record the date, time, and reason for breaking the blind, and the names of 
personnel involved.

Limited vendors (ie, the bioanalytical laboratory and other vendor personnel, if any, that are 
responsible for PK analysis) will have access to the randomization codes to facilitate PK 
analytical work, and will be instructed to not communicate in any manner information associated 
with treatment assignment to any personnel at the clinical site, the Sponsor, or contract research 
organization (CRO).  
Post-randomization values for individual laboratory measures for LDL-C,
TC,
non-HDL, ApoB,
and hs-CRP, including any plasma concentration of bempedoic acid and 
its metabolite that may inadvertently suggest treatment assignment will not be available to 
personnel from the clinical site, the patient, the Sponsor, and CRO. 
An independent DMC will monitor unblinded accumulating patient safety and efficacy data until 
the last patient has completed study treatment.  In addition, data on SAEs and deaths will be 
monitored by the DMC during this period.  At each DMC review, relevant unblinded safety and 
efficacy information from ongoing studies will be provided to the DMC by an independent, 
unblinded
programmer and statistician.  Additional details will be provided in a DMC 
Charter. 
8.4. 
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.

INVESTIGATIONAL MEDICINAL PRODUCT  
9.1. 
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. 
PCSK9i will be provided as background therapy.  This will be dispensed and administered 
during clinic visits and will be stored and taken as commercially labeled.   
The MED ID number (an identifier on the study drug packaging) will be obtained via IWRS and 
used to select PCSK9i and double-blind IMP for the treatment period from available clinical 
supplies at the clinical site.  
Double-blind IMP will be dispensed in 35-day supply increments to patients by appropriate 
clinical site personnel.  Patients will receive one 35-day supply bottle at Day 1 (Visit T1) and at 
Month 1 (Visit T2).  
Please see Pharmacy Manual for detailed storage requirements and management instructions. 
9.2. 
Administration of Investigational Medicinal Product 
Patients will be instructed to ingest IMP starting at Visit T1 for the duration of treatment period 
orally once daily (once every 24 hours) at approximately the same time each day with water.  
IMP may be taken with or without food.  On clinic visit days, patients will be instructed to delay 
ingestion of IMP until all study procedures have been completed.  If a patient arrives at clinic on 
Visits T1, T2, or T3 without having fasted or having taken IMP before arriving at the clinic, 
reschedule the visit (the next day or as soon as possible) so that the fasting and dosing 
requirements have been met.  Patients will be instructed to return all packaging and unused IMP 
at each clinic visit.  
If the patient forgets to take IMP at the usual time on nonclinic visit days, it may be taken up to 
12 hours later the same day.  After that time, the patient should not take IMP that day and should 
resume ingestion of IMP the following day.  If a patient fails to take IMP, details describing the 
reasons for nondosing should be documented in the patient’s medical records and eCRF.  Extra 
IMP (7 extra days per bottle) is provided and can be used, if needed, prior to the next visit or to 
replace a dose of IMP that cannot be used because it is lost or damaged. 
PCSK9i will be administered on site at Visits S2, S3, S4, T1, and T2.  Doses will be stored and 
administered as required in prescribing information

Investigational Medicinal Product Accountability 
Accurate records of the receipt of all IMP and PCSK9i shipped by the Sponsor (or designee) and 
the disposition of the IMP and PCSK9 must be maintained.  
IMP records or logs must comply with applicable regulations, local law, and guidelines, and 
should include: 
• Amount received/placed in storage area 
• Amount currently in storage area 
• MED ID number for all IMP 
• Dates and initials of person(s) responsible for IMP/PCSK9i inventory (including 
entry/movement/disposition) 
• Date and amount of IMP/PCSK9i dispensed to each patient, including unique patient 
identifiers 
• Date that IMP/PCSK9i was returned by patient, assessment of compliance, and 
relevant documentation of discrepancies 
• Nonstudy disposition (eg, lost, broken, wasted) 
• Amount returned to Sponsor/Sponsor’s designee/destroyed or amount destroyed per 
local standard operating procedure (SOP) following accountability by site monitor. 
9.4. 
Investigational Medicinal Product Handling and Disposal 
Upon completion or termination of the study, all used and unused IMP with the IMP packaging 
must be returned to the Sponsor (or designee) for eventual destruction unless otherwise 
authorized by the Sponsor.  All IMP returns must be accompanied by the appropriate 
documentation.

STUDY PROCEDURES 
10.1. 
Informed Consent 
The patient must be adequately informed of the nature and risks of the study and understand the 
informed consent document (ICD).  No study-related procedure will be performed until the 
patient has been completely informed of the study, has freely consented to take part in the study, 
and has signed and dated an ICD approved by the Sponsor (or designee) and the IRB or IEC.   
10.2. 
Procedures and Schedule of Assessments 
Patients who provide informed consent and sign the ICD will be eligible to begin screening for 
the study.  The study is comprised of 3 distinct periods:  screening, PCSK9i run-in and double-
blind treatment.  
The schedule of study events is provided in Appendix 1.  However, a patient can be seen at any 
time for reasons of safety.  
Data will be captured on eCRFs.  Randomization, drug supply (re)ordering, and patient tracking 
will occur via IWRS.  Instructions for these systems will be provided separately. 
10.2.1. 
Screening Month -4.5 (Visit S1) 
The screening period will begin with a screening visit that will occur approximately 18 weeks 
prior to randomization.  Visit S1 will allow the Investigator to assess the patient’s preliminary 
eligibility.  After the patient provides written informed consent (see Section 10.1), the patient 
will undergo the following assessments and procedures at Visit S1: 
• Demographics 
• Clinically relevant medical history  
• Concomitant and prohibited medication review 
• Height (cm), weight (kg), body mass index (BMI)  
• Vital signs  
• Clinical laboratory evaluations:  
− Hematology, blood chemistry, and urinalysis 
− Basic fasting lipids (TC, calculated LDL-C, 
, non-HDL-C, 
, and 
) 
− HbA1C 
− TSH 
− FSH (in appropriate female patients) 
− Serum pregnancy test (on appropriate female patients) 
• Serology (including HBsAg, Hepatitis C virus [HCV])

• Review of all inclusion/exclusion criteria that can be assessed at this time 
• Conduct diet and exercise counseling 
• Contact IWRS to register the patient  
Patients who meet all enrollment criteria that can be assessed following review of the S1 central 
clinical laboratory results (available several days after Visit S1) will be instructed to washout of 
all lipid-regulating drugs and supplements and to maintain consistent diet and exercise patterns 
throughout the study.  Patients who fail to meet any entry criterion that can be assessed at 
Visit S1 are considered to be screen failures and are not required to return for additional visits 
(although a patient can be seen at any time for safety reasons). 
10.2.2. 
PCSK9i Run-in Month -3 (Visit S2) 
Prior to scheduling Visit S2, review the screening clinical results to evaluate whether the patient 
continues to meet eligibility criteria. 
• If the patient meets eligibility criteria, then schedule the Visit S2 and proceed with the 
Visit S2 procedures 
The patient will undergo the following assessments and procedures at (Visit S2) 
• Concomitant and prohibited medication review (ongoing) 
• Assess AEs (starting from signing of the informed consent document) 
• Physical examination (PE) 
• Vital signs 
• Basic fasting lipids (TC, calculated LDL-C, 
, non-HDL-C, 
, and 
) 
• ApoB and hs-CRP  
• First PCSK9i monthly injection.  Verification of lipid entry criteria (LDL-C value of 
>160 mg/dL and triglycerides <500 mg/dL) must be obtained before starting PCSK9i 
• Schedule next visit (S3 has to be at least 30 days ± 3 days from the first dose of 
PCSK9)  
− PCSK9i injections must be administered consistently throughout the trial within 
30 ± 3 days from the previous dose.  Efficacy will vary if the doses are not 
consistently administered. 
Note:  Local labs can be used to assess LDL-C and TGs for entry.  All other labs must be 
run via the central lab.  If using a central lab or a local lab with a delay in obtaining 
results, an optional visit to administer PCSK9 may be scheduled.  Patients need to be on 
Repatha 420 mg for at least 30 days ± 3 days before conducting Visit S3.

the Visit T1 procedures 
If the patient has met all inclusion criteria, none of the exclusion criteria, and has been on 
Repatha 420 mg for 30 ± 3 days during each month of the PCSK9 run-in period, the patient 
may be randomized into the double-blind treatment period.  Patients who fail to meet any entry 
criterion prior to randomization are considered to be screen failures, will not be randomized into 
a treatment group, and are not required to return for additional visits.  Patients are considered 
randomized once all eligibility criteria are confirmed and a randomization number is obtained by 
the IWRS on the day of first dose.

10.3. 
Subject Withdrawal Criteria 
10.3.1. 
Early Withdrawal from the Study 
Patients must remain in the study until the last scheduled visit at Month 2 (Visit T3) to be 
considered as having completed participation in the study.  
Patients who temporarily withdraw from IMP prior to Month 2 (Visit T3) for any reason may 
restart IMP providing that 1) the patient and the investigator are in agreement regarding this 
course of action, 2) the patient has been off of IMP for 2 weeks or less; and 3) IMP can be started 
as soon as possible.  For cases where the patient has been off of IMP for more than 4 weeks, the 
investigator must contact the medical monitor for approval prior to restarting IMP. 
The patient’s decision to participate in the clinical study is voluntary.  Patients may refuse to 
continue in the study and/or withdraw from participation in this study at any time, for any reason, 
specified or unspecified, and without penalty or loss of benefits to which the patient is otherwise 
entitled.  
It is the right and duty of the Investigator to interrupt the treatment of any patient whose health or 
well-being may be threatened by continuation in this study.  Such patients should be withdrawn 
from the study and should not be continued under a modified regimen. 
Patients who are withdrawn from the study may not re-enter.  The reasons for withdrawal from 
this study may include: 
• Patient’s withdrawal of consent 
• Failure to comply with the protocol 
• Lost to follow-up 
• Illness, condition, or procedural complication (including AEs) affecting the patient’s 
ability to participate or requiring prohibited medication 
• The Sponsor or Investigator terminates the study  
• In the Investigator’s judgment, it is deemed in the best interest of the patient to 
discontinue his/her participation in the study 
• Any other reason 
If a patient is lost to follow-up, every reasonable effort must be made by the clinical site 
personnel to contact the patient and determine the reason for discontinuation/withdrawal.  The 
measures taken to follow-up must be documented. 
10.3.2. 
Procedures for Early Withdrawal 
If a patient withdraws or is removed from the study for any reason, all End of Study procedures 
should be completed.  Reason for withdrawal, date of the discontinuation, and date of the last 
dose of study drug should be recorded in the appropriate section of the eCRF.  Additionally, the 
discontinuation visit date must be registered in IWRS.  Study drug assigned to the withdrawn 
patient may not be assigned to another patient.

All effort should be made to have each patient complete all study visits on schedule according to 
the protocol.  Accommodations for early or late visits in special circumstances will be considered 
by the Sponsor to prevent early withdrawal.  Written notice (regardless of cause) is to be 
provided within 48 hours of the withdrawal to the Sponsor personnel or the Medical Monitor.  At 
the time of discontinuation, every effort should be made to ensure all relevant procedures and 
evaluations scheduled for the final study visit are performed.  Except in the case of a medical 
emergency, the procedures and assessments detailed in Section 10.2.7 will be performed upon 
the discontinuation of the study.

11. 
ASSESSMENT OF SAFETY 
11.1. 
Safety Parameters 
At all clinic visits, investigators will review all safety information including vital signs, AEs, and 
concomitant medications and will ensure that the collected data are recorded into the appropriate 
eCRF.  Additionally, clinical laboratory samples will be collected and sent for analysis and the 
investigator will review the results to ensure continued patient safety while participating in the 
study.  
11.1.1. 
Demographic/Medical History 
Demographic data and a complete medical history will be obtained from the patient.  For medical 
history, conditions that are relevant and/or clinically significant should be captured with at least a 
start date (month and year) and whether the condition is ongoing or resolved.  All surgeries 
regardless of date should be reported.  
11.1.2. 
Vital Signs 
Vital signs will include DBP and SBP as well as heart rate. 
The patient should sit quietly for 5 minutes prior to collection of vital signs.  At all time points, 
vitals will be collected prior to blood collection.  Blood pressure (BP) and heart rate will be 
measured using a calibrated, fully automated machine with a cuff that is appropriate to the size 
of the upper arm.  If a fully automated machine is not available, BP may be measured manually.  
The same method (either automated or manual) and the same arm (right or left) must be used 
throughout the study.  The patient should be in a seated position with feet touching the floor.  
Patients should be seated quietly for at least 5 minutes in a chair with their backs supported, their 
feet flat on the ground, and their arms bared and supported at heart level. 
11.1.3. 
Weight, Height, and Body Mass Index 
Weight will be measured on a calibrated scale while fasted and after voiding.  Body weight will 
be measured while fasting, using consistent scales, after voiding, and without shoes and 
outerwear (eg, coats).  
Height will be measured using standard clinic procedures.  
BMI will be calculated using the formula:  
BMI (kg/m2) = weight in kg / (height in meters)2

Trough PK plasma concentrations of bempedoic acid and its metabolite ESP15228 will be 
collected prior to dosing at Visits T1, T2, and T3.  See lab manual for additional details. 
Patients will be in a seated position during the blood collection.  Collection schedule and 
instructions are provided in the Clinical Laboratory Manual.  A description of the sample 
collection, storage, and shipping are described in Section 11.1.5.3. 
11.1.5.3. Sample Collection, Storage, and Shipping 
Clinical laboratory 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.   
Blood draws for lipids, 
, and glucose must meet the criteria listed below.  If these criteria 
have not been met, these blood samples will NOT be collected.  If these criteria can be met by 
rescheduling the clinic visit to occur within 3 days, the lipid, 
, and/or glucose blood samples 
will be collected at the rescheduled clinic visit only.  
• Blood samples will be drawn after a minimum 10-hour fast (water is allowed) 
11.1.5.4. 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.  The Investigator may repeat the 
laboratory test or request additional tests to verify the results of the original laboratory test.

Page 48 of 114 
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.  All clinically significant laboratory abnormalities 
occurring during the study that were not present at baseline should be followed and evaluated 
with additional tests if necessary, until diagnosis of the underlying cause or resolution.  Specific 
monitoring and management guidelines for laboratories of special interest are outlined in the 
sections below. 
11.1.5.4.1. Monitoring and Management of Elevated Liver Function Tests 
If at any time after randomization a patient experiences a new ALT and/or AST >3 × ULN, the 
patient will undergo repeat confirmatory liver function test (LFT) assessment as soon as is 
reasonably possible, preferably within 3 to 7 days of the laboratory result becoming available.  
Repeat LFT assessment will include:  1) measurement of ALT, AST, alkaline phosphatase, total 
and direct bilirubin, prothrombin time (PT)/international normalized ratio (INR), eosinophil 
count, CK, antihepatitis A virus (total), HBsAg (confirmation of screening measurement), HCV 
(confirmation of screening measurement), and anticytomegalovirus/immunoglobulin M; 
2) history of concomitant medication use; 3) history of exposure to environmental chemical 
agents, including ethanol; and 4) query for related symptoms.  Additionally, further testing such 
as liver ultrasound or magnetic resonance imaging (MRI) scanning may be warranted to rule out 
additional pathology depending on clinical presentation and should be discussed with the 
Sponsor personnel or the authorized Medical Monitor.  
• If repeat LFT assessment confirms ALT and/or AST >3 × ULN, consideration should 
be given to withdrawing the patient and administering no further doses of study drug.  
At the investigator’s discretion, study drug may be interrupted and the patient 
rechallenged with study drug after LFTs have returned to baseline levels.  
• If repeat LFT assessment confirms ALT and/or AST >5 × ULN, patient should be 
withdrawn from IMP treatment, but will be asked to continue to be followed for 
safety using the protocol-specified visit schedule (see Appendix 1). 
• If repeat LFT assessment confirms ALT and/or AST >3 × ULN in addition to any of 
the following, the patient should be given no further IMP treatment, but will be asked 
to continue to be followed for safety using the protocol-specified visit schedule (see 
Appendix 1): 
− TB >2 × ULN 
Note:  In the case of patients with Gilbert’s disease, TB will be fractionated and 
the determination of 2 × ULN will be based upon direct (conjugated) bilirubin. 
− INR >1.5 × ULN (unless the patient is on stable dose of anticoagulation 
medication) 
− Appearance or worsening of right upper abdominal discomfort, anorexia, fatigue, 
nausea, vomiting, fever, rash, or eosinophilia

11.1.5.4.2. Monitoring and Management of Elevated Serum Creatinine 
If at any time after randomization, a patient experiences a decrease in eGFR to the level of 
15 mL/min/1.73 m2) or if the patient experiences acute renal failure, the patient should be 
withdrawn from IMP treatment but will be asked to continue to be followed for safety using the 
protocol-specified visit schedule (see Appendix 1) 
11.1.5.4.3. Monitoring and Management of Elevated Creatine Kinase 
If at any time after randomization a patient experiences a marked CK elevation >5 × ULN, the 
patient will undergo repeat confirmatory assessment as soon as is reasonably possible, preferably 
within 3 to 7 days of the laboratory result becoming available.  
Repeat CK assessment will include query for related symptoms.  
• If the repeat CK assessment confirms an unexplained (ie, not associated with recent 
trauma or physically strenuous activity) CK abnormality >5 × ULN, if asymptomatic, 
the patient should receive further assessment and investigation into the cause, assess 
whether there is renal injury, and measure CK approximately weekly or more 
frequently if clinically indicated until resolution.  If CK levels continue to rise; IMP 
should be discontinued.  
• If symptomatic, the following should be completed: 
− Hold IMP 
− Clarification of the nature, duration, and intensity of muscle symptoms 
− Review possible predisposing factors, such as unaccustomed exercise, heavy 
alcohol intake, viral illness (consider performing serology)  
− Evaluation for additional diagnoses or other conditions which can cause 
myopathy including muscle tenderness (by PE), weakness, rash, measurement of 
serum creatinine, dipstick urinalysis with microscopy if indicated 
− Obtain clinical chemistries to assess the possibility of lactic acidosis 
− Follow symptoms and CK until the abnormality has resolved 
− If based on the above evaluation an alternative explanation is suspected, 
consideration can be given to resuming IMP once CK returns to baseline levels 
− If no alternative explanation exists, consideration should be given to withdrawing 
the patient from IMP treatment.  
• If the repeat CK assessment confirms an unexplained (ie, not associated with recent 
trauma or physically strenuous activity) CK abnormality as listed below, the patient 
should be withdrawn and given no further doses of study drug:  
− >10 × ULN, even in the absence of symptoms.  
− In all cases, evaluate the signs/symptoms and laboratory evaluations as outlined 
above.

• If the patient is withdrawn from IMP treatment, the patient should be asked to 
continue being followed for safety using the protocol-specified visit schedule (see 
Appendix 1). 
11.1.5.5. Monitoring and Management of Potential Hypoglycemia and Metabolic Acidosis 
Patients will be educated on the signs and symptoms of hypoglycemia.  If such signs and 
symptoms are experienced, patients will be instructed to report these signs and symptoms to the 
investigator.  
During each study visit, patients will be reminded to report all signs and symptoms associated 
with hypoglycemia to the investigator.  For each occurrence of patient-reported signs and 
symptoms associated with hypoglycemia, the investigator will discuss these symptoms with the 
patient and assess whether they are attributable to hypoglycemia or to another potential cause.  
All investigator-confirmed occurrences of hypoglycemia will be recorded as an AE.  All 
occurrences of signs and symptoms that are not confirmed by the investigator to be attributable 
to hypoglycemia will be reported using the appropriate diagnosis. 
Clinical laboratories will be assessed to determine any signs of anion gap metabolic acidosis.  If 
laboratories are consistent with metabolic acidosis, immediate follow up with the patient for 
further medical evaluation of the acidosis will occur.  This event should be captured as an AE.

12. 
ADVERSE AND SERIOUS ADVERSE EVENTS 
12.1. 
Adverse Events 
12.1.1. 
Definition of Adverse Events 
An AE is defined as 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.  The investigator is responsible for ensuring that any adverse 
events observed by the investigator or reported by the patient are recorded in the patient’s 
medical record.  
An AE can be: 
• Any unfavorable and unintended sign/symptom, including an abnormal laboratory 
finding, 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 
• Laboratory abnormality or diagnostic test abnormalities (eg, x-ray) should be reported 
as an AE if one of the following occurs   
− Treatment required due to the abnormality 
− Discontinuation of IMP 
− Per Investigator judgement 
• TEAEs are defined as AEs that begin or worsen after the first dose of study drug 
administration, as defined in the Statistical Analysis Plan (SAP). 
12.1.2. 
Adverse Drug Reaction 
All noxious and unintended responses to a medicinal product related to any dose should be 
considered an adverse drug reaction (ADR).  “Responses” to a medicinal product means that a 
causal relationship between the 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). 
12.1.3. 
Reporting for Adverse Events 
All AEs occurring during the course of the study (starting from signing informed consent 
through 30 days after last dose of study treatment) will be collected on the AE eCRF.  Patients 
should be instructed to report any AE that they experience to the investigator.  Investigators 
should make an assessment for AEs at each visit and record the event on the appropriate AE 
eCRF.

Page 52 of 114 
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.  A cluster of signs 
and symptoms that results from a single cause should be reported as a single AE (eg, fever, 
elevated white blood cells [WBC], cough, abnormal chest x-ray, etc, can all be reported as 
“pneumonia” if that is the final diagnosis).  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 should be recorded as the AE, not the procedure itself.  
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 worsens 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 findings that are detected during 
the study or are present at baseline and significantly worsen during the study should be reported 
as AEs, as described below.  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. 
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 
Each AE is to be evaluated for duration, severity, seriousness, and causal relationship to the IMP.  
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 
• Investigator’s assessment of relationship to IMP or PCSK9i. 
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 IMP administration should be determined by the investigator or study 
physician after thorough consideration of all facts that are available. 
12.1.4. 
Severity 
It is the investigator’s responsibility to assess the intensity (severity) of an AE.  
The severity of the AE will be characterized as mild, moderate, or severe according to the 
following definitions: 
• Mild:  Events are usually transient and do not interfere with the patient’s daily 
activities 
• Moderate:  Events introduce a low level of inconvenience or concern to the patient 
and may interfere with daily activities  
• Severe:  Events interrupt the patient’s usual daily activity, are incapacitating with 
inability to do usual activities, or significantly affect clinical status and warrant 
intervention and/or close follow-up  
Note:  A severe AE need not be serious and an SAE need not, by definition, be severe. 
12.1.5. 
Relationship 
It is the investigator’s responsibility to assess the relationship between the IMP and the AE.  The 
degree of “relatedness” of the AE to the IMP 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. 
• Possible:  Temporal association, but other etiologies are likely the cause.  However, 
involvement of the IMP cannot be excluded. 
• Probable:  Temporal association, other etiologies are possible but unlikely.  The event 
may respond if the IMP is discontinued. 
• Definite:  Established temporal association with administration of the IMP with no 
other more probable cause.  Typically, the event should resolve when the IMP is 
discontinued and recur on rechallenge. 
12.1.6. 
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.

Page 54 of 114 
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 or 
stabilization of the event(s). 
Patients with AEs related to IMP that are ongoing at study discontinuation or completion must be 
followed until resolution, until deemed stable/chronic, or for 30 days after study completion, 
whichever comes first, with the exception of patients reporting SAEs (see Section 12.2.2). 
12.1.7. 
Treatment-Emergent Adverse Events 
TEAE are defined as AEs that begin or worsen after the first dose of study drug administration, 
as defined in the SAP. 
12.2. 
Serious Adverse Events 
12.2.1. 
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 inpatient 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:  An emergency room visit without hospital admission does not meet inpatient 
hospitalization criteria, nor does hospitalization for an elective or outpatient procedure scheduled 
or planned before signing of informed consent.  However, unexpected complications and/or 
prolongation of hospitalization that occur during elective or outpatient surgery should be 
recorded as AEs and assessed for seriousness.  Admission to the hospital for social or situational 
reasons (eg, no place to stay, live too far away to come for hospital visits) will not be considered 
inpatient hospitalizations.  
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.

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 
12.2.2. 
Reporting Serious Adverse Events 
All SAEs occurring from the time of informed consent until 30 days following study completion/ 
discontinuation must be reported by the Principal Investigator or designee to the designated 
Safety contact within 24 hours of knowledge of the event.  All SAEs that the investigator 
considers related to IMP that occur after the 30-day follow-up period of the study period must be 
also reported to the Sponsor.  
To report the SAE, the SAE information should be entered on to the AE eCRF in the EDC 
database within 24 hours of becoming aware of the event.  If you have questions, please call the 
designated Safety contact for assistance.  
Detailed instructions and contact information for the Safety designee will be provided in the SAE 
Completion Guidelines.  
The investigator is required to submit SAE reports to their IRB/IEC in accordance with local 
requirements.  All investigators involved in studies using the same investigational product will 
receive any safety alert notifications for onward submission to their local IRB as required.  All 
reports sent to investigators will be blinded. 
All SAEs should be recorded on the eCRF and source documents.  Criteria for documenting the 
relationship to IMP 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 
information on the AE eCRF and submit any supporting documentation (eg, patient discharge 
summary or autopsy reports) to designated Safety contact.  
The Sponsor (and/or legally transferred designee) will report SAEs and suspected and 
unexpected serious adverse reactions (SUSARs) as required by global regulatory authorities, 
IECs/IRBs, and/or investigators/institutions in compliance with all reporting requirements 
according to local regulations, laws, and Good Clinical Practices (GCPs).  The investigator 
should notify their IEC/IRB of SAEs occurring at their site and other SAE reports received from 
the Sponsor, in accordance with local procedures and statutes.

12.2.3. 
Reporting of Patient Death 
The death of any patient during the study or within 30 days after the last dose of study treatment 
must be reported as an SAE. 
12.2.4. 
Reports of Pregnancy and Lactation 
Although not considered an SAE (unless an event occurs with a serious outcome), any event of 
pregnancy will be collected by the designated Safety contact.  If a female patient should become 
pregnant during the course of the study or within 30 days after last dose of study treatment, the 
Principal Investigator or designee must contact the designated Safety contact within 24 hours of 
knowledge of the pregnancy.  In addition, a paper Pregnancy Report Form must be completed 
and submitted to the Safety contact. 
Patients who become pregnant must discontinue study medication immediately and will continue 
to be followed until the pregnancy is completed.  Once the outcome of the pregnancy is known, 
the paper Pregnancy Outcome Report Form must be completed and submitted to the Safety 
contact.  Patients who are breastfeeding are excluded from this study and should discontinue 
study medication. 
12.3. 
Adverse Events of Special Interest 
Muscle:  Muscle events have been associated with statins (Thompson 2003) and other lipid-
lowering therapies and are mentioned in the product information for these therapies.  Muscle 
symptoms through AE review, CK elevations, and symptoms of potential myopathy will be 
closely monitored.  
Hepatic:  Hepatic function will be monitored throughout with the clinical safety labs.  More 
detailed investigation will occur if the safety clinical laboratory results are >3 × ULN. 
Neurocognitive Events:  Theoretically, it is possible that lipid-lowering agents that disrupt 
cholesterol homeostasis in the brain could impact neurological function, and there have been

reports of cognitive impairment (eg, memory loss) associated with the use of statin drugs 
(FDA 2012).  Summarization of events will occur using prespecified Medical Dictionary for 
Regulatory Activities (MedDRA) terms outlined in the SAP. 
12.4. 
Data Monitoring Committee 
An independent DMC will monitor unblinded accumulating patient safety and efficacy data until 
the last patient has completed study treatment.  In addition, data on SAEs and deaths, including 
clinical endpoints, will be monitored by the DMC during this period.  At each DMC review, 
relevant unblinded safety and efficacy information from ongoing studies of bempedoic acid will 
be provided to the DMC by an independent unblinded statistician and programmer.  Additional 
details will be provided in a DMC Charter. 
12.5. 
Assessment of Lipid Endpoints 
12.5.1. 
Lipid Parameters 
After randomization, patients will return to clinic every month.  Clinical laboratory samples will 
be collected and analyzed for calculated LDL-C and lipid and cardiometabolic biomarkers 
including non-HDL-C,
 TC, ApoB,
 and
 at baseline and all clinic visits for 
evaluation of bempedoic acid effects on lipids and cardiometabolic parameters.  
12.5.2. 
Clinical Laboratory Tests (Lipids) 
Clinical laboratory samples will be collected at all clinic visits.  
Blood draws for lipids (and glucose) must meet the criteria below.  If these criteria have not been 
met, these blood samples will NOT be collected.  If these criteria can be met by rescheduling 
clinic visit to occur within 3 days, these blood samples will be collected at the rescheduled 
clinic visit only.  
• Blood samples will be drawn after a minimum 10-hour fast (water is allowed)  
Patients are encouraged to be in a seated position during the blood collection.  Clinical laboratory 
parameters and tests will include those listed in Table 4.  Collection schedule and instructions are 
provided in the Clinical Laboratory Manual.  A description of the sample collection, storage, and 
shipping as well as monitoring and management of abnormal laboratories are described in 
Section 11.1.5. 
When vital signs and laboratory samples are to be collected at the same time point, vital sign 
measurements will precede laboratory sample collection.

STATISTICS 
13.1. 
General Considerations 
The statistical analyses described in this section will be performed as further outlined in a 
separate SAP.  The SAP will supersede the protocol in the event of any differences between the 
2 documents in the plans for data analysis, and the protocol will be amended if appropriate.  The 
SAP will be included as an appendix in the clinical study report for this protocol. 
Summary statistics for continuous variables will include the number of patients, mean, median, 
standard deviation or standard error, minimum, and maximum. For categorical variables, the 
frequency and percentage will be given. 
13.2. 
Determination of Sample Size 
The planned total sample size for this study is 52 with 26 patients in the bempedoic acid 180 mg 
group and 26 in the placebo group.  This sample size is expected to
 
 
  
13.3. 
Analysis Populations  
The Full Analysis Set (FAS), used for all of the efficacy analyses, is defined as all randomized 
patients with a baseline lipid value, at least 1 postbaseline lipid value, and having taken their 
study drug within 2 days of the lipid measurement.  The FAS is also known as the modified 
intention-to-treat (mITT) set of patients.  Patients in the FAS will be included in their 
randomized treatment group, regardless of the treatment they actually received.  Other subsets of 
the FAS will be considered to evaluate primary and secondary endpoints as sensitivity analyses 
and the details will be described in the SAP. 
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.  
13.4. 
Disposition, Demographics, and Baseline Characteristics 
Disposition, including reason for withdrawal from the study drug and/or 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. 
13.5. 
Primary Endpoint 
The primary efficacy endpoint is the percent change from baseline to Month 2 in LDL-C.  The 
primary efficacy endpoint will be analyzed using analysis of covariance (ANCOVA), with 

Bempedoic Acid

treatment group as a factor and baseline LDL-C as a covariate.  The details of the ANCOVA 
model and options to correct for unequal variances will be described in the SAP.  Baseline 
LDL-C is defined as the average of S4 and Day 1 values, if only 1 value is available, then that 
single value will be used as baseline.  The ANCOVA will be performed using the FAS, with 
patients included in their randomized treatment group regardless of the treatment they actually 
received.  Patients who are missing their Month 2 LDL-C will have their Month 2 value imputed 
by last observation carried forward (LOCF).  The least squares mean (LSM) and standard error 
(SE) for percent change estimate will be provided for both treatment groups, along with the 
placebo-corrected LSM, its 95% confidence interval (CI) and associated p-value.   
The ANCOVA assumptions will be examined and nonparametric test or transformation of the 
data will be considered if these assumptions are not met. 
13.6. 
Secondary and Exploratory Efficacy Endpoints 
The secondary efficacy endpoints (percent change from baseline to Month 1 in LDL-C; change 
from baseline to Months 1 and 2 in LDL-C; percent change from baseline to Months 1 and 2 in 
ApoB, non-HDL-C,TC, hs-CRP 
and 
), will be analyzed using the ANCOVA method 
similar to the primary endpoint.  Baseline value for TC, non-HDL-C,
will 
be the average of S4 and Day 1 values; ApoB and hs-CRP will be the Day 1 value, if only 
1 value is available, the single value will be used as the baseline.  Each ANCOVA will be 
performed using the FAS, with patients included in their randomized treatment group regardless 
of the treatment they actually received.  Missing values will be imputed using LOCF, where 
applicable.  For each 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. 
All efficacy endpoints will be analyzed at a significance level of 0.05, no multiplicity adjustment 
will be implemented. 
Exploratory endpoints will be summarized by descriptive statistics. 
13.7. 
Safety Endpoints 
The safety analyses for this study will be descriptive in nature, no statistical inferences are 
planned 
The subject incidence of all TEAE, SAEs, related AEs, AEs leading to withdrawal of study drug 
and/or study, fatal AEs, and AESI will be tabulated by system organ class (SOC) and preferred 
term in descending order of frequency and by treatment group.  
Clinical safety laboratories, including hematology, blood chemistry, HbA1C, glucose, and 
urinalysis; PE findings; vital signs; and weight will be summarized by the value and by change 
from baseline in the value (where appropriate) at each postbaseline time point. 
Hepatic Safety 
For liver-associated enzymes and TB, the number and percent of patients with abnormal values 
for ALT, AST, and TB will be summarized.  All liver-associated laboratory abnormalities will be 
assessed for 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. 
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.  Finally, muscle-
related AEs will be summarized by treatment group and by baseline eGFR category. 
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. 
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. 
13.8. 
Pharmacokinetics 
Three trough plasma concentrations of bempedoic acid and ESP15228 will be collected and 
summarized from patients at predose (T1), T2, and T3 for use in further developing the 
population PK model.

DATA HANDLING AND RECORDKEEPING 
17.1. 
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. 
17.2. 
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. 
17.3. 
Case Report Forms and Study Records 
Access to eCRFs will be provided to the clinical site. As part of the responsibilities assumed by 
participating in the study, the Investigator agrees to maintain adequate case histories for the 
patients treated as part of the research under this protocol.  The Investigator agrees to maintain 
accurate source documentation and eCRFs as part of the case histories.

Study records are comprised of source documents, eCRFs, and all other administrative 
documents (eg, IRB or IEC correspondence, clinical study materials and supplies shipment 
manifests, monitoring logs, and correspondence).  A study-specific binder will be provided with 
instructions for the maintenance of study records. 
Source documentation is defined as any handwritten or computer-generated document that 
contains medical information or test results that have been collected for or in support of the 
protocol specifications (eg, laboratory reports, clinic notes, study drug disposition log, pharmacy 
records, patient sign-in sheets, patient completed questionnaires, telephone logs, and x-rays).  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 eCRF completion guidelines following the evaluation.

NOTE: For patients who withdraw from study drug treatment, but consent to be followed for safety assessments and return to clinic for these visit, the visits will occur according 
to the protocol schedule.  Safety assessments should include clinical safety and basic lipid laboratories, adverse events (AEs), physical examination (PE), and vital signs.  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 T4 will be considered the End of Study 
(EOS)/Early Withdrawal from study and no further visits will be scheduled. 
1 An optional basic fasting lipid MAY be completed prior to S2, but must occur just prior to the next witnessed PCSK9i dose if patient fails to meet lipid entry criterion at 
Visit S1.  If this optional basic fasting lipid is completed, the average of the 2 lipid values will be used to determine eligibility. 
2 A recheck of blood pressure may be completed prior to T1 if the patient’s diastolic blood pressure (DBP) and/or systolic blood pressure (SBP) meet the exclusion criteria levels.  
Patients may randomize after blood pressure medications have been adjusted, the patients have been on stable doses of blood pressure medications for at least 2 weeks, and the 
repeat blood pressure values (DBP and/or SBP) do not meet exclusionary values.  Repeat labs may be completed prior to T1 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 T3/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).   
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

9 Clinical safety labs include hematology, blood chemistry, and urinalysis at all visits.  Please refer to laboratory manual for detailed schedule of tests. 
10 Basic fasting lipids include total cholesterol (TC), calculated low-density lipoprotein cholesterol (LDL-C),
 non-HDL-C,), and 
).   
11 Diet and exercise counseling per local and/or regional guidelines for the management of hyperlipidemia. 
12 Interactive web response system (IWRS) contact at either an early withdrawal or an EOS visit to register study discontinuation visit date. 
* Patients must be on PCSK9 for 30 ± 3 days during each month of the PCSK9 run-in period before initiating Day 1.   
** LDL-C must be ≥160 mg/dL and TG <500 mg/dL before initiating PCSK9i.  A local lab may be used to assess LDL-C and TG for eligibility prior to initiating Repatha, but a 
central lab must also be conducted at this visit.  
*** LDL-C must be ≥70 mg/dL to qualify for randomization.  Only a central lab may be used to assess entry LDL-C.

patients reach steady state prior to randomization.  
• Added/revised the following subject exclusion criteria to exclude patients that were 
recently on PCSK9 inhibitors as well as HeFH patients (this population will be 
studied in P3 trials): 
− Heterozygous Familial Hypercholesterolemia (HeFH) 
− Concomitant use of a PCSK9 inhibitor (Praluent® [alirocumab] or Repatha®

− Use of any experimental or investigational drugs within 30 days or 5 half-lives, 
whichever is longer 
• Updated contraception language to align with other P3 ETC-1002 clinical trials.  
− Added requirement that women use 2 rather than 1 form of acceptable 
contraception; expanded definition of true abstinence. 
• Removed remnant ECG language.  There are no ECG assessments, these were 
inadvertently added to the original protocol  
• Removed evaluation of PCSK9 levels from exploratory objectives and endpoints 
• Specified that LDL-C levels used for evaluation for study inclusion can use a local 
lab at S3, but that S4 evaluation can only use a central lab

Original Text: 
This is a Phase 2, randomized, double-blind, placebo-controlled, parallel group multicenter study 
that will be conducted at approximately 20 clinical sites in North America.  Screening 
Month -2.5 (Visit S1) will occur approximately 10 weeks prior to randomization.  After 
providing informed consent at Visit S1, patients will stop all background lipid-lowering therapy 
and lipid-modifying nutritional supplements, if applicable.  All patients will return to the clinic 
on Week -4 (Visit S2).  During this visit, patients with an LDL-C value ≥160 mg/dL (via central 
or local lab) and triglycerides <500 mg/dL (via central or local lab) will initiate PCSK9 
background therapy (Repatha 420 mg QM).  Sites that do not use a local lab may need to bring

This is a Phase 2, randomized, double-blind, placebo-controlled, parallel group multicenter study 
that will be conducted at approximately 20 clinical sites in North America.  Screening Visit S1 
will occur approximately 2.54.5 months prior to randomization.  After providing informed 
consent at Visit S1, patients will stop all background lipid-lowering therapy and lipid-modifying 
nutritional supplements, if applicable.  All patients will return to the clinic on Month -31 
(Visit S2).  During this visit, patients with an LDL-C value ≥160 mg/dL (via central or local lab) 
and triglycerides <500 mg/dL (via central or local lab) will initiate PCSK9i background therapy 
(Repatha 420 mg once monthly [QM]).  Sites that do not use a local lab may need to bring 
patients back for another visit to administer PCSK9i background therapy, as a qualifying LDL-C 
value is required prior to initiating the 3-month PCSK9i run-in periodinitial background 
therapy.  No other background lipid-modifying therapy except study-provided PCSK9i will be 
permitted during the trial.  After a 1 month (at least 30 days ±3 days) PCSK9i lipid stabilization 
period, patients will return to the clinic for Month -2 (Visit S3) followed by Month -1 (Visit S4) 
30 days ± 3 days later.  During these visits, Repatha will be administered, labs will be collected, 
and safety assessed. The sole purpose of this At visit S4, is to determine entry LDL-C will be 
checked a second time prior to randomization.  The sole purpose of this visit is to determine 
entry LDL-C prior to randomization. Patients with an LDL-C ≥70 mg/dL (via central or local

NOTE: For patients who withdraw from study drug treatment, but consent to be followed for safety assessments and return to 
clinic for these visit, the visits will occur according to the protocol schedule.  Safety assessments should include clinical safety 
and basic lipid laboratories, 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 T4 will be 
considered the End of Study (EOS)/Early Withdrawal from study and no further visits will be scheduled. 
1 An optional basic fasting lipid MAY be completed prior to S2, but must occur just prior to the next witnessed PCSK9i dose if 
patient fails to meet lipid entry criterion at Visit S1.  If this optional basic fasting lipid is completed, the average of the 2 lipid 
values will be used to determine eligibility. 
2 A recheck of blood pressure may be completed prior to T1 if the patient’s diastolic blood pressure (DBP) and/or systolic blood 
pressure (SBP) meet the exclusion criteria levels.  Patients may randomize after blood pressure medications have been 
adjusted, the patients have been on stable doses of blood pressure medications for at least 2 weeks, and the repeat blood 
pressure values (DBP and/or SBP) do not meet exclusionary values.  Repeat labs may be completed prior to T1 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 in the morning while fasting, using consistent scales, after voiding, and without shoes and 
outerwear (eg, coats).   
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 age 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.  Please refer to laboratory manual for 
detailed schedule of tests. 
10 Basic fasting lipids include total cholesterol (TC), calculated low-density lipoprotein cholesterol (LDL-C),
 non-HDL-C,), and
).   
11 Diet and exercise counseling per local and/or regional guidelines for the management of hyperlipidemia. 
12 Interactive web response system (IWRS) contact at either an early withdrawal or an EOS visit to register study discontinuation 
visit date. 
* Patients must be on PCSK9 for at least 30 days before initiating Day 1.  Day 1 should occur immediately (ideally within 
3 days) after S3, once LDL-C eligibility is established 
** LDL-C must be ≥160 mg/dL and TG <500 mg/dL before initiating PCSK9i.  A local lab may be used to assess LDL-C and 
TG.  
*** LDL-C must be ≥70 mg/dL to qualify for randomization.  A local lab may be used to assess entry LDL-C.
