Brief summary:
This study is being done to learn more about evolocumab in Chinese people with primary hypercholesterolemia or mixed dyslipidemia. This study will see if evolocumab will reduce low density lipoprotein cholesterol (LDL-C) in Chinese people who are also taking a certain type of lipid-lowering medication (statins with or without ezetimibe) and whether it causes any side effects.

Detailed description:
This is a phase 3, multicenter, double-blind, randomized, placebo-controlled study of evolocumab in Chinese participants with hypercholesterolemia and mixed dyslipidemia. Participants who have signed the informed consent form (ICF) will have fasting lipids measured and all inclusion and exclusion criteria assessed. All eligible participants must be taking a maximum appropriate dose of an approved statin, not requiring up titration. Participants should maintain their current diet and exercise regimen.

Treatment and follow-up period will be 12 weeks with an additional phone call or other participant contact at week 14 for those receiving investigational product every 2 weeks (Q2W). The end of study (EOS) for participants on once monthly (QM) investigational product is at the week 12 visit, which must be at least 30 days post last dose of investigational product.

Evolocumab or placebo will be administered by self-injection under the skin at the study site or in an appropriate non-clinic setting (e.g., at home) by spring based prefilled auto injector/pen (AI/Pen). Participants must tolerate an injection of placebo with a prefilled auto injector/pen device to be used during the study prior to randomization.

Participants will be randomly added to 1 of 4 groups using a 2:2:1:1 ratio:

evolocumab 140 mg Q2W (86 participants total) evolocumab 420 mg QM (86 participants total) placebo Q2W (44 participants total) placebo QM (43 participants total). The dose frequencies of Q2W and QM will not be blinded but the identity of investigational product evolocumab or placebo will be blinded.

Arms: arm 1: Placebo subcutaneous (SC) Q2W for 12 weeks arm 2: Placebo SC QM for 12 weeks arm 3: Evolocumab 140 mg SC Q2W for 12 weeks arm 4: Evolocumab 420 mg SC QM for 12 weeks
Interventions: intervention 1: evolocumab intervention 2: placebo
Intervention descriptions: intervention 1: Evolocumab will be administered per pre-filled auto-injector pen (AI/Pen). Participants will receive evolocumab (AMG 145) every 2 weeks or monthly subcutaneously. intervention 2: Placebo will be administered per pre-filled auto-injector pen (AI/Pen). Participants will receive placebo every 2 weeks or monthly subcutaneously.

Protocol Synopsis 
Title:  A Double-blind, Randomized, Placebo-controlled, Multicenter Study to Evaluate Safety and 
Efficacy of Evolocumab (AMG 145) in addition to Optimal Stable Background Statin Therapy in 
Chinese Subjects with Primary Hypercholesterolemia and Mixed Dyslipidemia 
Study Phase:  3 
Indication:  Primary Hypercholesterolemia and mixed dyslipidemia 
Primary Objective:  To evaluate the effect of 12 weeks of subcutaneous (SC) evolocumab every 
2 weeks or every 4 weeks, compared with placebo, on percent change from baseline in 
low-density lipoprotein cholesterol (LDL-C) when used in addition to optimal stable background 
statin therapy in Chinese subjects with primary hypercholesterolemia and mixed dyslipidemia. 
Secondary Objective(s):  To evaluate the effect of 12 weeks of SC evolocumab Q2W or QM, 
compared with placebo, on change from baseline in LDL-C, achievement of target LDL-C 
< 70 mg/dL (1.8 mmol/L), LDL-C response (50% reduction of LDL-C from baseline) and percent 
change from baseline in non-high-density lipoprotein cholesterol (non-HDL-C), apolipoprotein B 
(ApoB), total cholesterol, lipoprotein(a) [Lp(a)], triglycerides, HDL-C, very low-density lipoprotein 
cholesterol (VLDL-C) when used in addition to optimal stable background statin therapy in 
Chinese subjects with primary hypercholesterolemia and mixed dyslipidemia. 
Hypotheses:  The hypothesis is the dosing regimens of evolocumab SC 140 mg Q2W and 
420 mg QM will be well tolerated and will result in greater reduction of LDL-C, as defined by the 
mean percent change from baseline at weeks 10 and 12 and percent change from baseline at 
week 12, than placebo when used in combination with optimal stable background statin therapy in 
Chinese subjects with primary hypercholesterolemia and mixed dyslipidemia. 
Co-Primary Endpoints:   
• 
Mean percent change from baseline in LDL-C at weeks 10 and 12  
• 
Percent change from baseline in LDL-C at week 12

Tier 1: 
• 
Change from baseline in LDL-C  
• 
Percent change from baseline in non-HDL-C  
• 
Percent change from baseline in ApoB  
• 
Percent change from baseline in total cholesterol  
• 
Achievement of target LDL-C < 70 mg/dL (1.8 mmol/L)  
• 
LDL-C response (50% reduction of LDL-C from baseline)  
Tier 2:  
•

Study Design:  This is a phase 3, multicenter, double-blind, randomized, placebo-controlled 
study of evolocumab in Chinese subjects with hypercholesterolemia and mixed dyslipidemia.  
Subjects who have signed the informed consent form (ICF), will have fasting lipids measured and 
all inclusion and exclusion criteria assessed.  Subjects should maintain their current diet and 
exercise regimen.  Subjects who, in the opinion of the investigator, require statin up-titration or 
dietary adjustment can be rescreened after 1 month. Subjects can only be rescreened once.  
Statins may not be down-titrated with subsequent rescreened.  Baseline statin therapy is

expected to be continued unchanged throughout the study.  Subjects will be randomized 2:2:1:1 
into the following treatment arms:  
• 
evolocumab SC 140 mg Q2W,  
• 
evolocumab SC 420 mg QM,  
• 
placebo SC Q2W, or  
• 
placebo SC QM.   
Randomization will be stratified by entry cardiovascular (CV) risk (high/very high CV risk vs not 
high/very high CV risk).   
The overall sample size will be approximately 450 subjects (150 subjects for each evolocumab 
dosing regimen).  The sample size for each placebo will be approximately 75 subjects. 
Evolocumab and placebo will be administered SC at the study site or in an appropriate non-clinic 
setting (eg, at home) by spring based prefilled autoinjector/pen (AI/Pen).  The dose frequencies of 
Q2W and QM will not be blinded but the identity of investigational product evolocumab or 
matching SC placebo) will be blinded.   
Subjects must tolerate a SC injection of placebo with a prefilled autoinjector/pen device to be 
used during the study prior to randomization.  
All central laboratory results of Apolipoprotein (Apo) A1, ApoB, Lp (a), PCSK9, high sensitivity 
C-reactive protein (hsCRP) will be blinded until unblinding of the clinical database and will not be 
reported to the investigator. Post-investigational product treatment central laboratory results of 
the lipid panel will be blinded until unblinding of the clinical database and will not be reported to 
the investigator. Investigators should not perform non protocol testing of these analytes during a 
subject’s study participation and until at least 12 weeks after last investigational product 
administration, or the subject’s end of study (EOS), whichever is later. 
Approximately 40 sites in China will participate in this study.  Treatment and follow-up period will 
be 12 weeks with an additional phone call or other subject contact at week 14 for subjects 
receiving investigational product Q2W.  The EOS for subjects on QM investigational product is at 
the week 12 visit which must be at least 30 days post last dose of investigational product. The 
EOS for subjects on Q2W investigational product is a telephone call from the site at week 14 (and 
at least 30 days post last dose of investigational product) for any potential adverse events, 
adverse device effects (ADEs), serious adverse events and disease related events.  Subjects will 
be encouraged to complete all planned visits regardless of their adherence to investigational 
product administration. 
The primary completion is when all subjects have completed study treatment and have had the 
opportunity to complete the 12 week visit. 
End of trial will occur when the last subject has completed or discontinues study treatment and 
has had the opportunity to complete the safety follow-up visit. 
Sample Size:  A total 450 subjects are planned to be enrolled in this study. 
Summary of Subject Eligibility Criteria:  Males and females, ≥ 18 to years of age are eligible 
for this study.  Subject must be on an approved statin for at least 4 weeks, before LDL-C 
screening and, in the opinion of the investigator, not require uptitration. Subject must have fasting 
LDL-C ≥ 80mg/dL at screening, and meet one of the criteria listed in Section 4.1.1 to be 
considered high/very high CV risk.  Subject must have fasting triglycerides ≤ 400 mg/dL 
(4.5 mmol/L) at screening, and be able to tolerate a screening placebo injection 
Major exclusions are myocardial infarction, unstable angina, percutaneous coronary intervention 
(PCI), coronary artery bypass graft (CABG) within the last 3 months, planned coronary or other 
revascularization within 20 weeks of screening, New York Heart Association (NYHA) III or IV 
heart failure, uncontrolled serious cardiac arrhythmia, diabetes, or hypertension, and severe renal 
dysfunction. 
For a full list of eligibility criteria, please refer to Section 4.1.  
Investigational Product 
Amgen Investigational Product Dosage and Administration:  Evolocumab and matched 
placebo will be administered SC using a spring-based prefilled AI/Pen.  Each prefilled AI/Pen

contains 1.0 mL of deliverable volume.  The Q2W administration will occur via 1 AI/Pen, while the 
QM administration will occur via 3 AI/Pens. 
Non-investigational Product 
Amgen Non-investigational Product Dosage and Administration:  None  
Non-Amgen Non-investigational Product Dosage and Administration:  All eligible subjects 
must be taking a maximum appropriate dose of an approved statin, not requiring uptitration. 
All other lipid lowering drugs that are allowed per protocol and that the subject may be taking, 
must be commercially available. Subjects must be on an approved statin with maximum 
appropriate (optimal) stable daily dose with or without ezetimibe for at least 4 weeks before 
LDL-C screening and, in the opinion of the investigator, not requiring uptitration. 
They must remain on the same daily statin background therapy (drug and dose), with or without 
ezetimibe, throughout the study from signing of the ICF until the EOS. If statin therapy is 
discontinued, or changed during the study, the reason for adjusting medication (eg. adverse 
event, noncompliance, etc) should be recorded. 
Procedures:  Subjects being considered for participation and who have signed informed consent, 
will be assessed for inclusion and exclusion criteria.  Medical and medication history will be 
obtained.  During screening, all subjects will undergo physical examination, and central labs 
including fasting lipids will be collected. If a subject has not met all eligibility criteria at the end of 
the 4-week window, the subject will be registered as a screen fail.  Subjects who screen fail due 
to the LDL-C below the limit for eligibility during final screening cannot be rescreened for this 
study. Suitable subjects who are ineligible at the initial screening for other reasons and have not 
been randomized can be re-consented and rescreened once at a later time unless they withdraw 
from screening, provided the study is still enrolling subjects. Subjects will undergo SC placebo 
injection prior to randomization with a device to be used during the study (AI/pen).  Subjects who 
tolerate the placebo injection, complete all screening procedures, and successfully meet all 
eligibility criteria at the end of screening will be randomized and will return to the study site for 
Day 1 procedures while continuing their background lipid lowering treatment (if applicable).  The 
dosing regimens are evolocumab 140 mg SC Q2W or 420 mg SC QM. Study visits will occur at 
screening, baseline (Day 1), Week 8, Week 10, Week 12, and Week 14 (Q2W subjects only). 
Fasting lipids will be tested for all subjects at baseline, Week 8, Week 10, and Week 12 towards 
analysis of primary and secondary endpoints. Safety data will be collected at all time points as 
indicated in the Schedule of Assessments (Table 2).   
For a full list of study procedures, including the timing of each procedure, please refer to 
Section 7 and the Schedule of Assessments (Table 2).   
Statistical Considerations:   
 
Analysis Sets 
The full analysis set (FAS) includes all randomized subjects who received at least 1 dose of 
investigational product. This analysis set will be used in both efficacy and safety analyses. In 
efficacy analyses, subjects will be grouped according to their randomized treatment group 
assignment. For safety analyses, subjects will be grouped according to their randomized 
treatment group assignment with the following exception:  if a subject receives treatment 
throughout the study that is different than the randomized treatment group assignment, then the 
subject will be grouped by the actual treatment group.  
The completer analysis set (CAS) includes subjects in the FAS who adhered to the scheduled 
investigational product regimen and have observed values for the co-primary endpoints. 
General Considerations 
Efficacy and safety analyses will be performed on the FAS. Unless specified otherwise, the FAS 
will be the default analysis set in this study and data will be summarized by randomized treatment 
group. Analyses will be performed separately by each dose frequency (Q2W and QM) unless 
specified otherwise. The superiority of evolocumab to placebo will be assessed for all efficacy 
endpoints. 
Subject disposition, demographics, baseline characteristics, and exposure to investigational 
product will be summarized.

Summary statistics for continuous variables will include the number of subjects, mean, median, 
standard deviation, or standard error, minimum, and maximum. For categorical 
variables, the frequency and percentage will be given. 
Missing data will not be imputed for safety endpoints.   
Analysis of Co-Primary Efficacy Endpoints 
To assess the co-primary endpoints of the mean percent change from baseline in LDL-C at 
weeks 10 and 12 and the percent change in LDL-C from baseline at week 12, a repeated 
measures linear effects model will be used on the FAS in each dose frequency to compare the 
efficacy of evolocumab with placebo. The repeated measures model will include terms for 
treatment group, stratification factor, scheduled visit and the interaction of treatment with 
scheduled visit. 
Subgroup Analysis 
If applicable, subgroup analyses on the co-primary efficacy endpoints will be conducted using the 
stratification factor and baseline covariates. 
Secondary Efficacy Endpoint(s) 
The statistical model and testing of the tier 1 secondary efficacy endpoints will be similar to the 
primary analysis of the co-primary endpoints. The secondary efficacy endpoints of LDL-C 
response (achievement of LDL-C < 70 mg/dL and achievement of > 50% LDL-C reduction from 
baseline) will be analyzed using the Cochran-Mantel Haenszel (CMH) test adjusted by the 
stratification factor. 
Analyses of the tier 2 secondary efficacy endpoints will use the same analysis model 
as the tier 1 endpoints, and testing will use a union-intersection test. 
Safety Endpoints 
The current Medical Dictionary for Regulatory Activities (MedDRA) version at the time of the data 
lock will be used to code all adverse events to a system organ class and a preferred 
term. Subject incidence of all treatment emergent adverse events will be tabulated by system 
organ class and preferred term. Tables of fatal adverse events, serious adverse events, 
adverse events leading to withdrawal from investigational product, device-related adverse events, 
and significant treatment-emergent adverse events will also be provided. Subject incidence of 
disease-related events and fatal disease-related events will be tabulated by system organ class 
and preferred term. 
Measurements of selected laboratory parameters and vital signs will be summarized over time. 
The incidence and percentages of subjects who develop anti-evolocumab antibodies (binding and 
neutralizing) at any time will be tabulated. 
For a full description of statistical analysis methods, please refer to Section 10.

BACKGROUND AND RATIONALE 
2.1 
Disease 
In China, about 230 million people, 1 in 5 adults, have cardiovascular disease (CVD).  In 
2010, 154.8 per 100,000 deaths per year are estimated to be associated with CVDs in 
urban areas and 163.1 per 100,000 in rural areas.  This number accounts for 
20.9%/17.9% (urban/rural) of China's total number of deaths per year.  In China, heart 
attacks and strokes account for the number 1 and 3 causes of death.  China now ranks 
among the top 10 countries in the world for total incidence of CVD.  Projected annual

cardiovascular events are predicted to increase by 50% between 2010 and 2030 based 
on population aging and growth alone in China.  
These trends are thought to result from growing urbanization and industrialization which 
has resulted in a rise in cardiovascular risk factors such as glucose intolerance, 
dyslipidemia, and hypertension.  The rationale for treatment of dyslipidemia, particularly 
elevated LDL-C, extends from extensive clinical study data in both primary and 
secondary prevention that demonstrates the reduction in total cholesterol, non-HDL-C, 
and most importantly, LDL-C through pharmacological therapies, particularly statins, 
lowers the risk of CVD events. 
A recent Cholesterol Treatment Trialists’ (CTT) Collaboration meta-analysis 
(CTT Collaboration, 2010), which included 21 randomized controlled studies of statin 
versus control involving nearly 170,000 patients, showed that for every ~ 1 mmol/L 
reduction in LDL-C, there was an approximately 20% reduction in the risk of major 
vascular events (coronary death, non-fatal myocardial infarction, coronary 
revascularization, or stroke).  Importantly, this meta-analysis, which evaluated 5 studies 
that compared more versus less intensive statin therapy, did not find a LDL-C threshold; 
additional vascular risk reduction is possible in patients with low LDL-C. 
Statins are the most commonly used drugs for treating dyslipidemia.  However, the 
current status of lipid lowering therapy in China is unsatisfactory.  Several studies found 
that there is a low rate of achieving goal LDL-C levels among Chinese patients in 
general, and that this is particularly true in those at high risk or very high risk who require 
intensive LDL-C lowering therapy.  For example, results from China Cholesterol 
Education Program indicate that after moderate statin treatment (ie, 10-20 mg 
atorvastatin or 20-40 mg simvastatin), the rates of LDL-C goal achievement are only 
10.9% (< 70mg/dL) and 36.2% (< 100 mg/dL) and among outpatients at very high risk 
and high risk, respectively (Hu et al, 2008).  Results of the dyslipidemia international 
study (DYSIS) China study showed that 39.7% of coronary heart disease (CHD) patients 
with diabetes achieved LDL-C control far lower than in subjects with either CHD or 
diabetes alone (Zhao S et al, 2014).  Poor control rate of LDL-C is associated with 
increased risk of cardiovascular events, which leads to a heavy burden on families and 
society. 
There are certain limitations of statins.  Some Chinese patients respond poorly to the 
statin therapy.

As an example, the clinical study HPS2-THRIVE showed that almost 9.8% of Chinese 
patients were reported to have an LDL-C level > 2.0 mmol/L (77mg/dL), and 48.9% 
exceeded 1.5 mmol/L (58mg/dL) even with a dose of statin such as 40 mg/day 
simvastatin (HPS2 THRIVE Collaborative Group, 2013).  Although increasing the statin 
dose could help more patients to achieve their LDL-C goal, it is not wise to achieve a 
higher goal attainment rate by only using high-dose statin, as there is a "Rule of Six%" 
principle:  For each doubling of the statin dose, only an additional 6% further lowering of 
LDL C is achieved (Knopp, 1999). 
Meanwhile, high dose statins lead to increasing adverse effects, including increased liver 
and muscle related adverse effects (Silva et al, 2007) and a potential increased risk 
higher of new onset diabetes (Preiss et al, 2011).  This is particularly obvious in the 
Chinese population.  The HSP2-THRIVE study, which randomized 10932 Chinese 
patients, demonstrated a higher rate of adverse events in Chinese subjects who 
received only LDL-C lowering therapy (namely they were allocated into controlled arm 
receiving simvastatin or simvastatin plus ezetimibe) than in European patients who 
underwent the same treatment (HPS2-THRIVE Collaborative Group, 2013).  Statin 
related adverse effects are considered to be the main reason of the discontinuation of 
the drug.  The Clinical Pathways for Acute Coronary Syndromes in China study 
suggested that side effects were accountable for discontinuation of statin therapy in 23% 
of patients discharged from hospitals with a diagnosis of acute coronary syndrome 
(Bi et al, 2009).  Drug discontinuation due to adverse effects and poor patient 
compliance further impact attainment of LDL-C goals; consequently, this will lead to high 
incidence of cardiovascular events.

Investigator’s Brochure. 
2.3 
Rationale 
Despite achieving their LDL-C goals, approximately two-thirds of Chinese patients on 
lipid reduction therapy still have cardiovascular events (Libby, 2005).  While it is unlikely 
that this residual risk is entirely due to LDL-C concentrations above the goal articulated 
in recent treatment guidelines (Grundy et al, 2004; NCEP, 2002;), CTT Collaboration 
meta-analysis which assessed the relationship between LDL-C reduction and the 
cardiovascular events concluded that the relative risk decreases by 1% for every 
1.8 mg/dL reduction in LDL-D (CTT Collaboration, 2010).  Furthermore, therapies are

needed for individuals who are intolerant to statin therapy and cannot achieve their 
respective LDL C goals (Bruckert et al, 2005; Franc et al, 2003). 
Non-statin treatment options are currently available to lower LDL-C but their potency is 
limited, such that LDL-C reductions occur on the order of 15% to 20%.  Considering the 
remaining cardiovascular risk despite the availability of statin therapy, and given that 
non-statin treatment options have modest efficacy (ezetimibe, bile acid sequestrants 
[BAS], plant stanols) and/or are poorly tolerated (niacin and BAS), there is an unmet 
medical need for a potent, effective non-statin agent that will get a significant proportion 
of patients to LDL-C goal and further reduce cardiovascular risk.  Based on the current 
data, evolocumab, a fully human monoclonal antibody to PCSK9, may fulfill this need 
and may provide an important addition to the treatment of hyperlipidemia/dyslipidemia 
for individuals with hyperlipidemia. 
The rationale for the study design and study population is to investigate the effect of 
evolocumab on LDL across different levels of cardiovascular risk and baseline LDL 
levels.  The 2007 China Guideline on Prevention and Treatment of Dyslipidemia in 
Adults categorizes patients as high risk if they have coronary heart disease or coronary 
heart disease equivalent (documented atherosclerosis other than in the coronary 
arteries, diabetes mellitus or multiple cardiovascular risk factors).  The target LDL levels 
for these patients is < 80mg/dL for those with a history of acute coronary syndrome or 
both documented atherosclerosis and diabetes mellitus.  The target LDL for other high 
risk subjects was < 100mg/dL.  However since the release of subsequent international 
guidelines in 2007 the target for the latter high risk patients has in practice been moving 
lower.  Patients without very high or high risk features but receiving optimal stable 
background statin therapy in China are generally of moderate risk for which the 2007 
guidelines recommend a target LDL of < 130 mg/dL.  For these reasons the recruitment 
criteria for this trial is based on level of risk with high and very high risk subjects 
requiring an LDL at screening of at least 80mg/dL on optimal stable background statin 
therapy and the subjects without high risk features requiring an LDL of at least 
130 mg/dL. 
2.4 
Clinical Hypotheses 
The hypothesis is the dosing regimens of evolocumab SC 140 mg Q2W and 420 mg QM 
will be well tolerated and will result in greater reduction of LDL-C, as defined by the 
mean percent change from baseline at weeks 10 and 12 and percent change from 
baseline at week 12, than placebo when used in combination with optimal stable

mixed dyslipidemia.  
3. 
EXPERIMENTAL PLAN 
3.1 
Study Design 
The overall study design is described by a study schema at the end of the 
protocol synopsis section. 
This is a phase 3, multicenter, double-blind, randomized, placebo-controlled study of 
evolocumab in Chinese subjects with hypercholesterolemia and mixed dyslipidemia.  
Subjects who have signed the informed consent form (ICF), will have fasting lipids 
measured and all inclusion and exclusion criteria assessed.  Subjects should maintain 
their current diet and exercise regimen.  Subjects who, in the opinion of the investigator, 
require statin up-titration or dietary adjustment can be rescreened after 1 month.  
Subjects can only be rescreened once.  Statins may not be down-titrated with 
subsequent rescreened.  Baseline statin therapy is expected to be continued unchanged 
throughout the study.  Subjects will be randomized 2:2:1:1 into the following treatment 
arms:  
• 
evolocumab SC 140 mg Q2W,  
• 
evolocumab SC 420 mg QM,  
• 
placebo SC Q2W, or  
• 
placebo SC QM.   
Randomization will be stratified by entry CV risk (high/very high CV risk vs not high/very 
high CV risk).   
The overall sample size will be approximately 450 subjects (150 subjects for each 
evolocumab dosing regimen).  The sample size for each placebo will be approximately 
75 subjects. 
Evolocumab and placebo will be administered SC at the study site or in an appropriate 
non-clinic setting (eg, at home) by spring based prefilled autoinjector/pen (AI/Pen).  
Observed, in-clinic dosing will occur at Day 1 and Week 8 (± 3 days).  Subjects 
randomized to QM will self-administer in an appropriate non-clinic setting (eg, at home) 
at Week 4 (± 3 days).  Subjects randomized to Q2W will self-administer in an 
appropriate non-clinic setting (eg, at home) at Week 2, 4 and 6 (± 3 days).  The dose 
frequencies of Q2W and QM will not be blinded but the identity of investigational product 
(evolocumab or matching SC placebo) will be blinded.

Subjects must tolerate a SC injection of placebo with a prefilled AI/Pen device to be 
used during the study prior to randomization.  
All central laboratory results of ApoA1, ApoB, lipoprotein(a), PCSK9, hsCRP will be 
blinded until unblinding of the clinical database and will not be reported to the 
investigator.  Post-investigational product treatment central laboratory results of the lipid 
panel will be blinded until unblinding of the clinical database and will not be reported to 
the investigator.  Investigators should not perform non protocol testing of these analytes 
during a subject’s study participation and until at least 12 weeks after last investigational 
product administration, or the subject’s end of study (EOS), whichever is later. 
Approximately 40 sites in China will participate in this study.  Treatment and follow-up 
period will be 12 weeks with an additional phone call or other subject contact at week 14 
for subjects receiving investigational product Q2W.  The EOS for subjects on QM 
investigational product is at the week 12 visit which must be at least 30 days post last 
dose of investigational product.  The EOS for subjects on Q2W investigational product is 
a telephone call from the site at week 14 (and at least 30 days post last dose of 
investigational product) for any potential adverse events, adverse device effects (ADEs), 
serious adverse events and disease related events (DREs).  Subjects will be 
encouraged to complete all planned visits regardless of their adherence to 
investigational product administration. 
The study endpoints are defined in Section 10.1.1. 
3.2 
Number of Sites 
Approximately 40 sites in China will participate in this study.   
Sites that do not enroll subjects within 3 months of site initiation may be closed.   
3.3 
Number of Subjects 
Participants in this clinical investigation shall be referred to as “subjects”. 
A total of 450 subjects are planned to be enrolled in this study.

be 16 weeks (approximately 4 months) which includes screening, study treatment, and 
safety follow-up. For a subject on Q2W investigational product schedule, the maximum 
study duration will be 18 weeks (approximately 4.5 months), including a telephone 
contact by the site at week 14 to obtain potential adverse events, adverse device effects, 
serious adverse events and disease related events information.

i. 
A postmenopausal state is defined as no menses for 12 months 
without an alternative medical cause.  [A high follicle stimulating 
hormone (FSH) level in the postmenopausal range may be used 
to confirm a postmenopausal state in women not using hormonal 
contraception or hormonal replacement therapy (HRT).  However, 
in the absence of 12 months of amenorrhea, a single FSH 
measurement is insufficient.]

the study.  Otherwise, they must discontinue HRT to allow 
confirmation of postmenopausal status before study enrollment.  
Acceptable methods of effective birth control include:  
• 
sexual abstinence (defined as refraining from heterosexual intercourse 
during the entire period of risk associated with the study treatments; the 
reliability of sexual abstinence must be evaluated in relation to the 
duration of the trial and the preferred and usual lifestyle of the subject.  
[Periodic abstinence (eg., calendar, ovulation, symptothermal, 
postovulation methods), declaration of abstinence for the duration of a 
study, and withdrawal are not acceptable methods of contraception]) 
• 
bilateral tubal ligation/occlusion 
• 
vasectomized partner (provided that partner is the sole sexual partner of 
the female subject of childbearing potential and that the vasectomized 
partner has received medical assessment of the surgical success) 
• 
use of hormonal birth control methods (oral, intravaginal (eg. vaginal 
ring(s), transdermal, injectable, or implantable) 
• 
intrauterine devices (IUDs) 
• 
intrauterine hormonal releasing system (IUS) 
• 
2 barrier methods (each partner must use 1 barrier method) the male 
uses a condom and the female must choose either a diaphragm, OR 
cervical cap, OR contraceptive sponge with spermicide.  If spermicide is 
not commercially available in the country or region, the 2 barrier method 
without spermicide is acceptable.  (A female condom is not an option due 
to the risk of tearing when both partners use a condom.) 
Note: Additional medications given during treatment with investigational product 
may alter the contraceptive requirements.  These additional medications may 
require a change in the type of contraceptive methods and/or length of time that 
contraception is to be utilized and/or length of time breastfeeding (nursing) is to 
be avoided.  The investigator is to discuss these contraceptive changes with the 
study subject.  
221. 
Female subject is pregnant or breast feeding (nursing), planning to become 
pregnant or planning to breastfeed (nurse) during treatment with investigational 
product and/or within 15 weeks after the end of treatment with investigational 
product.  
5. 
SUBJECT ENROLLMENT 
Before subjects begin participation in any study-specific activities/procedures, Amgen 
requires a copy of the site’s written institutional review board/independent ethics 
committee (IRB/IEC) approval of the protocol, ICF, and all other subject information 
and/or recruitment material, if applicable (see Section 11.2).  All subjects must

personally sign and date the ICF before commencement of study specific 
activities/procedures. 
Upon completion of the screening period the subject is evaluated by the investigator and 
providing the subject continues to meet the inclusion/exclusion criteria, the subject is 
subsequently eligible to be enrolled in the study.  The investigator is to document this 
decision and date, in the subject’s medical record and in/on the enrollment case report 
form (CRF). 
Each subject who enters into the screening period for the study (defined as the point at 
which the subject signs the ICF) receives a unique subject identification number before 
any study-related activities/procedures are performed.  The subject identification number 
will be assigned by the interactive voice response system / interactive web response 
system (IVRS/IWRS).  This number will be used to identify the subject throughout the 
clinical study and must be used on all study documentation related to that subject.  
Subjects who, in the opinion of the investigator, require statin up-titration or dietary 
adjustment can be rescreened after 1 month.  Subjects can only be rescreened once.   
The subject identification number must remain constant throughout the entire clinical 
study; it must not be changed after initial assignment, including if a subject is 
rescreened.  This number will not necessarily be the same as the randomization number 
assigned for the study.   
5.1 
Randomization/Treatment Assignment 
Subjects will be considered enrolled on the day they are randomized.  Assignment to the 
4 treatment arms will be based on a computer-generated randomization schedule 
prepared by Amgen before the start of the study. 
Each subject will receive a unique randomization number.  Randomization will be 
stratified by entry CV risk (high/very high CV risk vs not high/very high CV risk). 
Once a subject has completed screening and continues to meet all eligibility criteria, a 
site representative will make the randomization call to the IVRS/IWRS to assign a 
randomization number to the subject.  The randomization call to the IVRS/IWRS is 
accomplished by entering the pertinent information detailed in the IVRS/IWRS user 
manual.  A confirmation fax or email will be sent to the site to verify that the correct 
information has been entered and to confirm the assignment of a randomization number.  
A subject will be considered randomized into the study when a randomization number is 
assigned.

The randomization date is to be documented in the subject’s medical record and on the 
enrollment CRF.  Randomization numbers will be provided to the site through an 
IVRS/IWRS. 
5.2 
Site Personnel Access to Individual Treatment Assignments 
A subject’s treatment assignment should only be unblinded when knowledge of the 
treatment is essential for the further management of the subject on this study. 
Unblinding at the study site for any other reason will be considered a protocol deviation. 
The investigator is strongly encouraged to contact the Amgen Clinical Trial Manager 
before unblinding any subject’s treatment assignment, but must do so within 1 working 
day after the event.

Vasectomized partner (provided that partner is the sole sexual partner of the female 
subject who is of childbearing potential and that the vasectomized partner has received 
medical assessment of the surgical success); Two barrier methods (one by each 
partner) and the female partner must use spermicide (if spermicide is commercially 
available) with the barrier method [the male must use a condom (latex or other synthetic 
material) and the female may select either a diaphragm, cervical cap or contraceptive 
sponge].  A female condom is not an option because there is a risk of tearing when both 
partners use a condom.  The reliability of true sexual abstinence must be evaluated by 
the investigator and be the preferred and usual lifestyle of the subject.   
If a female subject is suspected of being pregnant, the protocol-required therapies must 
be stopped immediately and may not be resumed until absence of pregnancy has been 
medically confirmed.   
Females not of childbearing potential are defined as:  Any female who is has had a 
hysterectomy, OR bilateral salpingectomy, OR bilateral oophorectomy, OR are 
post-menopausal.  Post-menopausal women are: 
• 
Age > 55 years with cessation of menses for 12 or more months  
• 
Age < 55 years but no spontaneous menses for at least 2 years 
• 
Age < 55 years and spontaneous menses within the past 1 year, but currently 
amenorrheic (eg, spontaneous or secondary to hysterectomy), AND with 
follicle-stimulating hormone levels > 40 IU/L, or postmenopausal estradiol levels 
< 5 ng/dL, or according to the definition of "postmenopausal range" for the laboratory 
involved. 
6.9.2 
Unacceptable Methods of Birth Control for Female Subjects 
Birth control methods that are considered unacceptable in clinical trials include:  periodic 
abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus 
interruptus), spermicides only, and lactational amenorrhoea method.

7.2 
General Study Procedures  
7.2.1 
Study Visit Definitions and Windows 
After signing the ICF, potential subjects will be evaluated to determine whether they fulfill 
the entry requirements listed in Section 4.1.  At screening, the subject should be 
reminded that participation in the study is contingent upon his or her screening test 
results.  The screening period begins the day the subject signs the ICF, and ends (after 
28 days) when the subject is randomized to receive the first dose of investigational 
product or fails the enrollment criteria. 
Refer to the applicable supplemental central laboratory, IVRS/IWRS, and study manuals 
for detailed collection and handling procedures.   
Subjects should be randomized before or on the day 1 visit, and initiate their first dose of 
investigational product within 5 days of randomization. 
The following visit windows (± 3 days) will apply to all visits during the treatment period 
of the study: 
• 
Week 8 
• 
Week 10  
• 
Week 12  
• 
Week 14 (Q2W subjects only) 
Study procedures for a specific visit may be completed on multiple days as long as all 
the procedures are completed within the visit window. 
7.2.2 
Description of Study Procedures 
The sections below provide a description of the individual study procedures listed in 
Section 7.2.3, Section 7.2.4, and Section 7.2.5.  Details regarding the collection, 
recording and reporting of adverse events, adverse device effects, serious adverse 
events, disease related events and/or other safety findings are provided in Section 9.2. 
7.2.2.1 
Informed Consent 
All subjects or legally acceptable representative must sign and personally date the 
IRB/IEC approved informed consent and provide subject assent if appropriate before 
any study specific procedures are performed. 
7.2.2.2 
Medical History 
The Investigator or designee will collect a complete medical history covering the period 
within 120 days prior to randomization.  Additionally, a targeted cardiovascular and 
diabetes medical history not limited to 120 days prior to randomization will be collected.

Targeted cardiovascular history including but not limited to cardiovascular risk factors, 
history of cardiovascular disease, revascularization procedures, family history, and 
diagnostic criteria for familial hypercholesterolemia will be collected.  
7.2.2.3 
Measurement of Vital Signs 
Blood pressure (BP) and heart rate (HR) measurements will be determined after the 
subject has been seated for at least 5 minutes.  The appropriate size cuff should be 
used.  During screening, BP measurements can be repeated if the previous reading is 
outside of the eligibility range.  The repeat BP measure should be taken at least 
2 minutes following the previous measure. 
7.2.2.4 
Measurement of Waist Circumference 
Subjects should wear minimal clothing to ensure that the measuring tape is correctly 
positioned.  Subjects should stand erect with the abdomen relaxed, arms at the sides, 
feet together and with their weight equally divided over both legs.  To perform the waist 
measurement, the lowest rib margin is first located.  The iliac crest is then palpated in 
the midaxillary line.  It is recommended to apply an elastic tape horizontally midway 
between the lowest rib margin and the iliac crest, and tie firmly so that it stays in position 
around the abdomen about the level of the umbilicus.  The elastic tape thus defines the 
level of the waist circumference, which can then be measured by positioning the 
measuring tape over the elastic tape. 
Subjects are asked to breathe normally, and to breathe out gently at the time of the 
measurement to prevent them from contracting their muscles or from holding their 
breath.  Measurements should be performed using the same procedure throughout the 
study.  The reading is taken to the nearest centimeter or ½ inch and entered in the 
source document. 
7.2.2.5 
Prior Therapies, Substance use History, and Concomitant 
Medications 
Throughout the study, investigators may prescribe any concomitant medications or 
treatments deemed necessary to provide adequate supportive care except for those 
listed above in Excluded Treatments and/or Procedures During Study Period. 
Prior general and targeted therapies (eg, statins and other lipid lowering therapy), taken 
120 days prior to randomization should be collected with the following information: 
therapy name, indication, dose, unit, frequency, route, start date and stop date.

If a targeted therapy is begun, discontinued, or changed during study, in addition to 
updates for the above information, the reason for adjusting medication (ie, adverse 
event, worsening of underlying condition, noncompliance etc) should be recorded. 
Concomitant therapies are to be collected from ICF through the EOS.   
7.2.2.6 
Pregnancy Test 
Pregnancy testing will occur in females of childbearing potential only. 
7.2.2.7 
Laboratory Assessments 
Subjects must be fasting overnight (no food or drinks other than water for ≥ 9 hours) 
before each study visit where fasting lipid samples are obtained.  If the subject is not 
fasting for the screening or the day 1 visit, no visit procedures are performed and the 
visit should be rescheduled within the applicable protocol windows.  If subject is not 
fasting after day 1, all procedures except fasting labs and investigational product 
administration, if applicable, will be performed and another visit should be scheduled, 
within the visit window if possible, for fasting labs and investigational product 
administration. 
All laboratory samples will be sent to the central laboratory.  Concentration values are 
provided in mmol/L for investigator convenience.  Conventional concentrations (mg/mL) 
will be used for the protocol, including for eligibility determination.  eGFR will be 
calculated by the central laboratory and will be provided to the site for eligibility 
determination.  Table 3 below outlines the specific analytes to be tested.

Blinding: 
In order to protect the blinding of the double-blind treatment period the following labs will 
be blinded post-investigational product treatment until unblinding of the clinical database 
and not reported to sites as noted below: 
• 
Blinded to the Amgen study team and site staff: lipid panel, ApoA1,ApoB, 
lipoprotein(a), hsCRP, and PCSK9 
Investigators should not perform non-protocol testing of these analytes during a subject’s 
study participation and until at least 12 weeks after last investigational product 
administration, or the subject’s EOS, whichever is later.  
Refer to the IPIM for a description regarding how responsible pharmacists and 
investigators will access treatment information via the IVR/IWR system, in the event that 
there is a need to break the blind.  The investigator is strongly encouraged to contact the 
Clinical Trial Manager before unblinding any subject’s treatment assignment, but must 
do so within 1 working day after the event. 
7.2.3

the day 1 visit, and initiate their first dose of investigational product within 5 days of 
randomization. 
7.2.3.1 
Rescreening 
Subjects who screen fail due to the LDL-C below the limit for eligibility during final 
screening cannot be rescreened for this study.   
Suitable subjects who are ineligible at the initial screening for other reasons and have 
not been randomized can be re-consented and rescreened once at a later time unless 
they withdraw from screening, provided the study is still enrolling subjects.  For subjects 
who are rescreened, data from the first screening period will not be used for the

Antibody Testing Procedures 
Blood sample(s) for Antibody testing are to be collected at baseline, Week 12, and 
during the early termination visit for the measurement of anti-evolocumab binding 
antibodies.  Samples testing positive for binding antibodies will also be tested for 
neutralizing antibodies and may be further characterized for quantity/titer, isotype, affinity 
and presence of immune complexes.  Additional blood samples may be obtained to rule 
out anti-evolocumab antibodies during the study.

Sites will be notified of any positive neutralizing antibody results to evolocumab for 
individual subjects at the end of the study for each subject.  If results are not provided, 
no neutralizing antibodies to evolocumab have been detected. 
Subjects who test positive for neutralizing antibodies to evolocumab at the final 
scheduled study visit  will be asked to return for additional follow-up testing.  This testing 
is to occur approximately every 3 months starting from when the site has been notified of 
the positive result, until:  (1) neutralizing antibodies are no longer detectable or (2) the 
subject has been followed for a period of at least 1 year (± 4 weeks) post administration 
of evolocumab.  All follow-up results, both positive and negative will be communicated to 
the sites.  More frequent testing (eg, every month) or testing for a longer period of time 
may be requested in the event of safety-related concerns.  Follow-up testing is not 
required where it is established that the subject did not receive evolocumab. 
Subjects who test positive for binding, non-neutralizing antibodies and have clinical 
sequelae that are considered potentially related to an anti-evolocumab antibody 
response may also be asked to return for additional follow-up testing.   
7.4 
Sample Storage and Destruction  
Any blood sample collected according to the Schedule of Assessments (Table 2) can be 
analyzed for any of the tests outlined in the protocol and for any tests necessary to 
minimize risks to study subjects.  This includes testing to ensure analytical methods 
produce reliable and valid data throughout the course of the study.  This can also 
include, but is not limited to, investigation of unexpected results, incurred sample 
reanalysis, and analyses for method transfer and comparability.  
All samples and associated results will be coded prior to being shipped from the site for 
analysis or storage.  Samples will be tracked using a unique identifier that is assigned to 
the samples for the study.  Results are stored in a secure database to ensure 
confidentiality.   
If informed consent is provided by the subject, Amgen can do additional testing on 
remaining samples (ie, residual and back-up) to investigate and better understand the 
scientific questions related to hyperlipidemia and mixed dyslipidemia, metabolic 
disorders, the dose response and/or prediction of response to evolocumab, and 
characterize aspects of the molecule (eg, mechanism of action/target, metabolites).  
Results from this analysis are to be documented and maintained, but are not necessarily 
reported as part of this study.  Samples can be retained for up to 20 years.

Since the evaluations are not expected to benefit the subject directly or to alter the 
treatment course, the results of pharmacogenetic, or other exploratory studies are not 
placed in the subject’s medical record and are not to be made available to the subject, 
members of the family, the personal physician, or other third parties, except as specified 
in the informed consent. 
The subject retains the right to request that the sample material be destroyed by 
contacting the investigator.  Following the request from the subject, the investigator is to 
provide the sponsor with the required study and subject number so that any remaining 
samples can be located and destroyed.  Samples will be destroyed once all 
protocol-defined procedures are completed.  However, information collected from 
samples prior to the request for destruction, will be retained by Amgen. 
The sponsor is the exclusive owner of any data, discoveries, or derivative materials from 
the sample materials and is responsible for the destruction of the sample(s) at the 
request of the subject through the investigator, at the end of the storage period, or as 
appropriate (eg, the scientific rationale for experimentation with a certain sample type no 
longer justifies keeping the sample).  If a commercial product is developed from this 
research project, the sponsor owns the commercial product.  The subject has no 
commercial rights to such product and has no commercial rights to the data, information, 
discoveries, or derivative materials gained or produced from the sample.  See 
Section 11.3 for subject confidentiality.

WITHDRAWAL FROM TREATMENT, PROCEDURES, AND STUDY 
8.1 
Subjects’ Decision to Withdraw 
Subjects have the right to withdraw from the study at any time and for any reason 
without prejudice to their future medical care by the physician or at the institution. 
Subjects (or a legally acceptable representative) can decline to continue receiving 
investigational product and/or other protocol-required therapies or procedures at any 
time during the study but continue participation in the study.  If this occurs, the 
investigator is to discuss with the subject the appropriate processes for discontinuation 
from investigational product, device or other protocol-required therapies and must 
discuss with the subject the options for continuation of the Schedule of Assessments 
(Table 2) and collection of data, including endpoints, adverse events, disease related 
events, and device related events, as applicable.  The investigator must document the 
change to the Schedule of Assessments (Table 2) and the level of follow-up that is 
agreed to by the subject (eg, in person, by telephone/mail, through family/friends, in

correspondence/communication with other physicians, from review of the medical 
records).   
Withdrawal of consent for a study means that the subject does not wish to receive 
further protocol-required therapies or procedures, and the subject does not wish to or is 
unable to continue further study participation.  Subject data up to withdrawal of consent 
will be included in the analysis of the study, and where permitted, publically available 
data can be included after withdrawal of consent.  The investigator is to discuss with the 
subject appropriate procedures for withdrawal from the study.   
8.2 
Investigator or Sponsor Decision to Withdraw or Terminate 
Subjects’ Participation Prior to Study Completion 
The investigator and/or sponsor can decide to withdraw a subject(s) from investigational 
product, device, and/or other protocol-required therapies, protocol procedures, or the 
study as a whole at any time prior to study completion.   
Subjects may be eligible for continued treatment with Amgen investigational product(s) 
and/or other protocol-required therapies by a separate protocol or as provided for by the 
local country’s regulatory mechanism, based on parameters consistent with 
Section 12.1.

SAFETY DATA COLLECTION, RECORDING, AND REPORTING 
9.1 
Definition of Safety Events 
9.1.1 
Disease Related Events 
Disease Related Events are events (serious or non-serious) anticipated to occur in the 
study population due to the underlying disease.  In this study, subjects are at risk or are 
known to have cardiovascular disease.  Therefore, disease-related events potentially 
include manifestations and complications of atherosclerotic vascular disease such as 
coronary artery disease, angina, myocardial infarction, ischemic stroke, transient 
ischemic attack, carotid artery disease, peripheral vascular disease (including 
complications such as claudication), and testing suggesting progression of 
atherosclerotic vascular disease.  Such events do not meet the definition of an adverse 
event unless assessed to be more severe than expected for the subject’s condition. 
Disease Related Events that do not qualify as Adverse Events or Serious Adverse 
Events:  
• 
An event which is part of the normal course of disease under study (eg, disease 
progression in oncology or hospitalization due to disease progression) is to be 
reported as a Disease Related Event.  
• 
Death is due to the disease under study; the event is to be recorded on the Event 
CRF. 
Disease Related Events that would qualify as an Adverse Event or Serious Adverse 
Event: 
• 
An event based on the underlying disease that is worse than expected as 
assessed by the investigator for the subject’s condition; or 
• 
If the investigator believes there is a causal relationship between the 
investigational product(s)/study treatment/protocol-required therapies and 
disease worsening, this must be reported as an Adverse Event or Serious 
Adverse Event.  
9.1.2 
Adverse Events 
An adverse event is defined as any untoward medical occurrence in a clinical trial 
subject.  The event does not necessarily have a causal relationship with study treatment.  
The investigator is responsible for ensuring that any adverse events observed by the 
investigator or reported by the subject are recorded in the subject’s medical record.   
The definition of adverse events includes worsening of a pre-existing medical condition.  
Worsening indicates that the pre-existing medical condition or underlying disease 
(eg, diabetes, migraine headaches, gout) has increased in severity, frequency, and/or 
Approved

duration more than would be expected, and/or has an association with a significantly 
worse outcome than expected.  A pre-existing condition that has not worsened more 
than anticipated (ie, more than usual fluctuation of disease) during the study or involves 
an intervention such as elective cosmetic surgery or a medical procedure while on study, 
is not considered an adverse event.   
Resolution of the adverse event will be recorded on the event CRF. 
An adverse device effect is any adverse event related to the use of a medical device.  
Adverse device effects include adverse events resulting from insufficient or inadequate 
instructions for use, adverse events resulting from any malfunction of the device, or 
adverse events resulting from use error or from intentional misuse of the device. 
The investigator’s clinical judgment is used to determine whether a subject is to be 
removed from treatment due to an adverse event.  In the event a subject, or subject’s 
legally acceptable representative requests to withdraw from protocol-required therapies 
or the study due to an adverse event, refer to Section 8.1 for additional instructions on 
the procedures recommended for safe withdrawal from protocol-required therapies or 
the study.   
9.1.3 
Serious Adverse Events 
A serious adverse event is defined as an adverse event that meets at least 1 of the 
following serious criteria (unless it meets the definition of a Disease Related Event as 
defined in Section 9.1.1): 
• 
fatal 
• 
life threatening (places the subject at immediate risk of death) 
• 
requires in-patient hospitalization or prolongation of existing hospitalization 
• 
results in persistent or significant disability/incapacity 
• 
congenital anomaly/birth defect 
• 
other medically important serious event 
A disease related event (eg, angina) is to be reported as a serious adverse event if: 
• 
the subject’s pre-existing condition becomes worse than what the investigator would 
consider typical for a patient with the same underlying condition, or 
• 
if the investigator believes a causal relationship exists between the investigational 
medicinal product(s)/protocol-required therapies and the event,  
• 
and the event meets at least 1 of the serious criteria.

CONFIDENTIAL 
 
 
An adverse event would meet the criterion of “requires hospitalization”, if the event 
necessitated an admission to a health care facility (eg, overnight stay).   
If an investigator considers an event to be clinically important, but it does not meet any 
of the serious criteria, the event could be classified as a serious adverse event under the 
criterion of “other medically important serious event”.  Examples of such events could 
include allergic bronchospasm, convulsions, blood dyscrasias, DILI (see Appendix A for 
DILI reporting criteria), or events that necessitate an emergency room visit, outpatient 
surgery, or urgent intervention. 
9.2 
Safety Event Reporting Procedures  
9.2.1 
Reporting Procedures for Disease Related Events 
The investigator is responsible for ensuring that all Disease Related Events observed by 
the investigator or reported by the subject that occur from the time of randomization/ 
after the first dose of investigational medicinal product(s)/study 
treatment/protocol-required therapies through 30 days after the last administration of 
investigational product or the EOS visit/safetyfollow-up visit whichever is later,  are 
recorded on the Event CRF as a Disease Related Event.   
Disease Related Events assessed by the investigator to be more severe than expected 
and/or related to the investigational medicinal product(s)/study 
treatment/protocol-required therapies, and determined to be serious, must be recorded 
on the Event CRF as Serious Adverse Events.   
Additionally, the investigator is required to report a fatal Disease Related Event on the 
Event CRF.   
9.2.2 
Adverse Events 
9.2.2.1 
Reporting Procedures for Adverse Events That do not Meet Serious 
Criteria 
Adverse events possibly related to study procedures, adverse device effects and serious 
adverse events are reported from signing of the ICF.  All other adverse events are 
reported from the time of randomization/first dose of investigational product/study 
treatment/protocol-required therapies.  The investigator is responsible for ensuring that 
all adverse events observed by the investigator or reported by the subject that occur 
from signing of the ICF or from the time of randomization/first dose of investigational 
product/study treatment/protocol-required therapies through 30 days after the last 
administration of investigational product or the EOS visit/safety follow-up visit or  
whichever is later, are reported using the Event CRF.

The investigator must assign the following adverse event attributes: 
• 
Adverse event diagnosis or syndrome(s), if known (if not known, signs or symptoms), 
• 
Dates of onset and resolution (if resolved), 
• 
Severity [and/or toxicity per protocol], 
• 
Assessment of relatedness to investigational product  (evolocumab/placebo  and/or 
the device (the prefilled Autoinjector/Pen), (AI/Pen) or other protocol-required 
therapies or study mandated procedures or activity 
• 
Action taken. 
The adverse event grading scale used will be the Common Terminology Criteria for 
Adverse Events (CTCAE).  The grading scale used in this study is described in 
Appendix A.   
The investigator must assess whether the adverse event is possibly related to 
investigational medicinal product (IMP) (evolocumab or placebo).  This relationship is 
indicated by a “yes” or “no” response to the question: Is there a reasonable possibility 
that the event may have been caused by evolocumab or placebo (investigational 
medicinal product)?   
The investigator must assess whether the adverse event is possibly related to the 
prefilled Autoinjector/Pen investigational device used to administer evolocumab or 
placebo.  The relationship is indicated by a “yes” or “no” response to the question: Is 
there a reasonable possibility that the event may have been caused by the 
investigational device? 
The investigator must assess whether the adverse event is possibly related to any 
study-mandated activity (eg, administration of investigational product,  protocol-required 
therapies, device(s) and/or procedure (including any screening procedure(s)).  This 
relationship is indicated by a “yes” or “no” response to the question:  “Is there a 
reasonable possibility that the event may have been caused by a study activity 
(eg, administration of SC placebo”?  
If the severity of an adverse event changes from the date of onset to the date of 
resolution, record a single event for each level of severity on the Event CRF. 
The investigator is responsible for reviewing laboratory test results and determining 
whether an abnormal value in an individual study subject represents a clinically 
significant change from the subject’s baseline values.  In general, abnormal laboratory 
findings without clinical significance (based on the investigator's judgment) are not to be

recorded as adverse events.  However, laboratory value changes that require treatment 
or adjustment in current therapy are considered adverse events.  Where applicable, 
clinical sequelae (not the laboratory abnormality) are to be recorded as the adverse 
event. 
The Investigator is expected to follow reported adverse events until stabilization or 
reversibility.  
9.2.2.2 
Reporting Procedures for Serious Adverse Events 
The investigator is responsible for ensuring that all serious adverse events observed by 
the investigator or reported by the subject that occur after signing of the ICF through 
30 days after the last administration of investigational product or the EOS/ safety 
follow-up visit, whichever is later, are recorded in the subject’s medical record and are 
submitted to Amgen.  This study will be utilizing electronic data capture for serious 
adverse events.  All serious adverse events must be submitted to Amgen within 
24 hours following the investigator’s knowledge of the event via the Event CRF.   
If the electronic data capture (EDC) system is unavailable to the site staff to report the 
serious adverse event, the information is to be reported to Amgen via an electronic 
serious adverse event Contingency Report Form within 24 hours of the investigator’s 
knowledge of the event.  See Appendix B for a sample of the electronic Serious Adverse 
Event Contingency Report Form.  For EDC studies where the first notification of a 
serious adverse event is reported to Amgen via the eSerious Adverse Event 
Contingency Report Form, the data must be entered into the EDC system when the 
system is again available. 
The investigator must assess whether the serious adverse event is possibly related to 
investigational medicinal product (IMP) (evolocumab or placebo).  This relationship is 
indicated by a “yes” or “no” response to the question: Is there a reasonable possibility 
that the event may have been caused by evolocumab or placebo (investigational 
medicinal product)?   
The investigator must assess whether the serious adverse event is possibly related to 
the prefilled Autoinjector/Pen investigational device used to administer evolocumab or

The investigator must assess whether the serious adverse event is possibly related to 
any study-mandated activity (eg, administration of investigational product,  
protocol-required therapies, device(s) and/or procedure (including any screening 
procedure(s)).  This relationship is indicated by a “yes” or “no” response to the question:  
“Is there a reasonable possibility that the event may have been caused by a study 
activity (eg, (eg, administration of investigational product, protocol-required therapies, 
device(s), and/or procedure”?) 
The investigator is expected to follow reported serious adverse events until stabilization 
or reversibility.  
New information relating to a previously reported serious adverse event must be 
submitted to Amgen.  All new information for serious adverse events must be sent to 
Amgen within 24 hours following knowledge of the new information.  If specifically 
requested, the investigator may need to provide additional follow-up information, such as 
discharge summaries, medical records, or extracts from the medical records.  
Information provided about the serious adverse event must be consistent with that 
recorded on the Event CRF. 
If a subject is permanently withdrawn from protocol-required therapies because of a 
serious adverse event, this information must be submitted to Amgen. 
To comply with worldwide reporting regulations for serious adverse events, the treatment 
assignment of subjects who develop serious, unexpected, and related adverse events 
may be unblinded by Amgen before submission to regulatory authorities.   
Amgen will report serious adverse events and/or suspected unexpected serious adverse 
reactions as required to regulatory authorities, investigators/institutions, and IRBs/IECs 
in compliance with all reporting requirements according to local regulations and good 
clinical practice.  
The investigator is to notify the appropriate IRB/IEC of serious adverse events occurring 
at the site and other adverse event reports received from Amgen, in accordance with 
local regulatory requirements and procedures. 
9.2.2.3 
Reporting Serious Adverse Events After the Protocol-required 
Reporting Period 
There is no requirement to monitor study subjects for serious adverse events following 
the protocol-required reporting period or after end of study.  However, these serious 
adverse events can be reported to Amgen.  In some countries (eg, European Union [EU]

member states), investigators are required to report serious adverse events that they 
become aware of after end of study.  If serious adverse events are reported, the 
investigator is to report them to Amgen within 24 hours following the investigator’s 
knowledge of the event. 
Serious adverse events reported outside of the protocol-required reporting period will be 
captured within the safety database as clinical trial cases for the purposes of expedited 
reporting.  
9.2.2.4 
Reporting a Safety Endpoint as a Study Endpoint 
Safety endpoints (eg, treatment emergent adverse events) that are study  endpoints are 
reported on an Event CRF.   
9.3 
Pregnancy and Lactation Reporting 
If a female subject becomes pregnant, or a male subject fathers a child, while the 
subject is taking evolocumab, report the pregnancy to Amgen Global Patient Safety as 
specified below. 
In addition to reporting any pregnancies occurring during the study, investigators should 
monitor for pregnancies that occur after the last dose of protocol-required therapies and 
for an additional 15 weeks after the end of treatment with investigational product, report 
the pregnancy to Amgen as specified below. 
The pregnancy should be reported to Amgen Global Patient Safety within 24 hours of 
the investigator’s knowledge of the event of a pregnancy.  Report a pregnancy on the 
Pregnancy Notification Worksheet (Appendix C).  Amgen Global Patient Safety will 
follow-up with the investigator regarding additional information that may be requested.  
If a female subject becomes pregnant during the study, the investigator should attempt 
to obtain information regarding the birth outcome and health of the infant.  If a male 
subject's female partner becomes pregnant, the investigator should discuss obtaining 
information regarding the birth outcome and health of the infant from the pregnant 
partner.   
If the outcome of the pregnancy meets a criterion for immediate classification as a 
Serious Adverse Event (eg, female subject experiences a spontaneous abortion, 
stillbirth, or neonatal death or there is a fetal or neonatal congenital anomaly) the 
investigator will report the event as a Serious Adverse Event.

Sample Size Considerations 
The sample size for this study has been considered to meet the requirement from 
regulatory authority (Drug Registration Regulation No 28; Oct 2007).   
The planned total sample size is 450 subjects (150 randomized to evolocumab SC 
140 mg Q2W, 150 randomized to evolocumab SC 420 mg QM, 75 randomized to 
placebo Q2W and 75 randomized to placebo QM).  The primary analysis will require the 
tests of each co-primary endpoint to be significant at level of 0.05.  The sample size 
should provide adequate power to determine the superiority of evolocumab (either Q2W 
or QM) relative to respective placebo (Q2W or QM) as measured by the co-primary 
endpoints.  
From the phase 3 study 20120122 and phase 2 study 20110155, the mean treatment 
effect of evolocumab 140 mg Q2W and 420 mg QM compared to placebo in percent 
change from baseline in LDL-C at week 12 was at least -50.3%, with the smallest 
treatment effect of -44.6% estimated from 95% confidence intervals.  For the co-primary 
endpoint of mean percent change from baseline in LDL-C at weeks 10 and 12, the mean 
treatment effect of evolocumab 140 mg Q2W and 420 mg QM compared to placebo was 
at least -62.4%, with the smallest treatment effect of -57.2% estimated from 95% 
confidence intervals.  
The assumed treatment effect of evolocumab in LDL-C reduction is 40%, with a common 
SD of 25%.  As the co-primary endpoints are correlated, the planned sample size will 
provide approximately at least 98% (99% x 99%) power in testing the superiority of each 
evolocumab dosing regimen over placebo on the co-primary endpoints, assuming a 10% 
drop out rate.   
Since the testing statistics from Q2W and QM groups are independent, there is a 96% 
chance (98% x 98%) to show the superiority of both evolocumab dosing regimens over 
placebo. 
The power calculation is derived using SAS Enterprise Guide version 6.1.

Access to Individual Subject Treatment Assignments by Amgen or 
Designees 
Blinded individuals will not have access to unblinded information until the study is 
formally unblinded.  Unblinding and potentially unblinding information should not be 
distributed to the study team, investigators or subjects prior to the study being formally 
unblinded (eg, the formal unblinding may occur at the final analysis rather than during 
the primary analysis) except as specified (eg, Section 5.2 and Section 9.2.2.2). 
Amgen staff members who are involved in randomization, biological sample 
management, performing PK, and anti-evolocumab assay analysis will have treatment 
assignment information, but will not have access to subject level data from the clinical 
trial database.

Planned Analyses 
10.4.1 
Primary Analysis 
The primary analysis will be performed when all subjects have either completed all

Planned Methods of Analysis  
10.5.1 
General Considerations 
Efficacy and safety analyses will be performed on the FAS.  Unless specified otherwise, 
the FAS will be the default analysis set in this study and data will be summarized by 
randomized treatment group.  Analyses will be performed separately by each dose 
frequency (Q2W and QM) unless specified otherwise.  The superiority of evolocumab to 
placebo will be assessed for all efficacy endpoints. 
Subject disposition, demographics, baseline characteristics, and exposure to 
investigational product will be summarized. 
Summary statistics for continuous variables will include the number of subjects, mean, 
median, standard deviation, or standard error, minimum, and maximum.  For categorical 
variables, the frequency and percentage will be given. 
Missing data will not be imputed for safety endpoints.  
Multiplicity Adjustment Method 
The analyses of Q2W and QM will be performed as 2 independent experiments.  In 
order to preserve the familywise error rate at 0.05 within each independent experiment 
(Q2W and QM), methods of adjusting for multiplicity due to multiple endpoints 
Approved

Co-Primary Efficacy Endpoints 
10.5.2.1 
Primary Analysis 
To assess the co-primary endpoints of the mean percent change from baseline in LDL-C 
at weeks 10 and 12 and the percent change in LDL-C from baseline at week 12, a 
repeated measures linear effects model will be used on the FAS in each dose frequency 
to compare the efficacy of evolocumab with placebo.  The repeated measures model will 
include terms for treatment group, stratification factor, scheduled visit and the interaction 
of treatment with scheduled visit.  Multiplicity adjustment procedures are defined in 
Section 10.5.1. 
10.5.2.2 
Subgroup Analysis 
If applicable, subgroup analyses on the co-primary efficacy endpoints will be conducted 
using the stratification factor and baseline covariates. 
10.5.3 
Secondary Efficacy Endpoint(s) 
The statistical model and testing of the tier 1 secondary efficacy endpoints will be similar 
to the primary analysis of the co-primary endpoints.  The secondary efficacy endpoints of 
LDL-C response (achievement of LDL-C < 70 mg/dL and achievement of > 50% LDL-C 
reduction from baseline) will be analyzed using the Cochran-Mantel Haenszel (CMH) 
test adjusted by the stratification factor. 
Analyses of the tier 2 secondary efficacy endpoints will use the same analysis model 
as the tier 1 endpoints, and testing will use a union-intersection test. 
Multiplicity adjustment procedures are defined in Section 10.5.1. 
10.5.4 
Safety Endpoints 
10.5.4.1 
Treatment Emergent Adverse Events 
The current Medical Dictionary for Regulatory Activities (MedDRA) version at the time of 
the data lock will be used to code all adverse events to a system organ class and a 
preferred term. 
Subject incidence of all treatment emergent adverse events will be tabulated by system 
organ class and preferred term.  Tables of fatal adverse events, serious adverse events, 
adverse events leading to withdrawal from investigational product, device-related 
adverse events, and significant treatment-emergent adverse events will also be 
provided.  Subject incidence of disease-related events and fatal disease-related events 
will be tabulated by system organ class and preferred term.

REGULATORY OBLIGATIONS 
11.1 
Informed Consent 
An initial sample ICF is provided for the investigator to prepare the informed consent 
document to be used at his or her site.  Updates to the template are to be communicated 
formally in writing from the Amgen Clinical Trial Manager to the investigator.  The written 
informed consent document is to be prepared in the language(s) of the potential patient 
population. 
Before a subject’s participation in the clinical study, the investigator is responsible for 
obtaining written informed consent from the subject or legally acceptable representative 
after adequate explanation of the aims, methods, anticipated benefits, and potential 
hazards of the study and before any protocol-specific screening procedures or any 
investigational product(s) is/are administered.  A legally acceptable representative is an 
individual or other body authorized under applicable law to consent, on behalf of a 
prospective subject, to the subject’s participation in the clinical study.  
The investigator is also responsible for asking the subject if the subject has a primary 
care physician and if the subject agrees to have his/her primary care physician informed 
of the subject’s participation in the clinical study.  If the subject agrees to such 
notification, the investigator is to inform the subject’s primary care physician of the 
subject’s participation in the clinical study.  If the subject does not have a primary care 
physician and the investigator will be acting in that capacity, the investigator is to 
document such in the subject’s medical record.

by an extension protocol or as provided for by the local country’s regulatory mechanism.  
However, Amgen reserves the unilateral right, at its sole discretion, to determine 
whether to supply Amgen investigational product(s) and by what mechanism, after 
termination of the study and before the product(s) is/are available commercially. 
12.2 
Study Documentation and Archive 
The investigator is to maintain a list of appropriately qualified persons to whom he/she 
has delegated study duties.  All persons authorized to make entries and/or corrections 
on CRFs will be included on the Amgen Delegation of Authority Form. 
Source documents are original documents, data, and records from which the subject’s 
CRF data are obtained.  These include but are not limited to hospital records, clinical 
and office charts, laboratory and pharmacy records, diaries, microfiches, radiographs, 
and correspondence. 
In this study, the IVR/IWR system captures the following data points and these are 
considered source data:  protocol number, site number, subject ID, gender, date of birth, 
date informed consent was signed, treatment group assignment, screen failure reason, 
randomization date, randomization number and investigational product box ID

In addition, all original source documents supporting entries in the CRFs must be 
maintained and be readily available. 
Retention of study documents will be governed by the Clinical Trial Agreement. 
12.3 
Study Monitoring and Data Collection 
The Amgen representative(s) and regulatory authority inspectors are responsible for 
contacting and visiting the investigator for the purpose of inspecting the facilities and, 
upon request, inspecting the various records of the clinical study (eg, CRFs and other 
pertinent data) provided that subject confidentiality is respected. 
The Clinical Monitor is responsible for verifying the CRFs at regular intervals throughout 
the study to verify adherence to the protocol; completeness, accuracy, and consistency 
of the data; and adherence to local regulations on the conduct of clinical research.  The 
Clinical Monitor is to have access to subject medical records and other study-related 
records needed to verify the entries on the CRFs. 
The investigator agrees to cooperate with the Clinical Monitor to ensure that any 
problems detected in the course of these monitoring visits, including delays in 
completing CRFs, are resolved. 
In accordance with ICH GCP and the sponsor’s audit plans, this study may be selected 
for audit by representatives from Amgen’s Global Research & Development Compliance 
and Audit function (or designees).  Inspection of site facilities (eg, pharmacy, 
protocol-required therapy storage areas, laboratories) and review of study-related 
records will occur to evaluate the study conduct and compliance with the protocol, 
ICH GCP, and applicable regulatory requirements. 
Data capture for this study is planned to be electronic: 
• 
All source documentation supporting entries into the CRFs must be maintained and 
readily available. 
• 
Updates to CRFs will be automatically documented through the software’s “audit 
trail”. 
• 
To ensure the quality of clinical data across all subjects and sites, a clinical data 
management review is performed on subject data received at Amgen.  During this 
review, subject data are checked for consistency, omissions, and any apparent 
discrepancies.  In addition, the data are reviewed for adherence to the protocol and 
GCP.  To resolve any questions arising from the clinical data management review 
process, data queries are created in the EDC system database for site resolution 
and subsequently closed by the EDC system or by an Amgen reviewer. 
• 
The investigator signs only the Investigator Verification Form for this electronic data 
capture study or the investigator applies an electronic signature in the EDC system if 
Approved

the study is set up to accept an electronic signature.  This signature indicates that 
investigator inspected or reviewed the data on the CRF, the data queries, and 
agrees with the content. 
Amgen (or designee) will perform Self-Evident Corrections (SEC) to obvious data errors 
in the clinical trial database.  SECs will be documented in the eCRF instructions 
available in the EDC system.  Examples of obvious data errors that may be corrected by 
Amgen (or designee) include deletion of obvious duplicate data (ie, the same results 
sent twice with the same date with different visit, [eg, week 4 and early termination]) and 
updating a specific response if the confirming datum is provided in the “other,specify” 
field (eg, for race, reason for ending study).  
12.4 
Investigator Responsibilities for Data Collection 
The investigator is responsible for complying with the requirements for all assessments 
and data collection (including subjects not receiving protocol-required therapies) as 
stipulated in the protocol for each subject in the study.  For subjects who withdraw prior 
to completion of all protocol-required visits and are unable or unwilling to continue the 
Schedule of Assessments (Table 2), the investigator can search publically available 
records [where permitted] to ascertain survival status.  This ensures that the data set(s) 
produced as an outcome of the study is/are as comprehensive as possible.   
12.5 
Language 
CRFs must be completed in English.  TRADENAMES® (if used) for concomitant 
medications may be entered in the local language.  Consult the country-specific 
language requirements. 
All written information and other material to be used by subjects and investigative staff 
must use vocabulary and language that are clearly understood.   
12.6 
Publication Policy 
To coordinate dissemination of data from this study, Amgen may facilitate the formation 
of a publication committee consisting of several investigators and appropriate Amgen 
staff, the governance and responsibilities of which are set forth in a Publication Charter.  
The committee is expected to solicit input and assistance from other investigators and to 
collaborate with authors and Amgen staff as appropriate as defined in the Publication 
Charter.  Membership on the committee (both for investigators and Amgen staff) does 
not guarantee authorship.  The criteria described below are to be met for every 
publication.

Authorship of any publications resulting from this study will be determined on the basis 
of the International Committee of Medical Journal Editors [ICMJE] Recommendations for 
the Conduct of Reporting, Editing, and Publications of Scholarly Work in Medical 
Journals, which states: 
• 
Authorship credit should be based on (1) substantial contributions to conception and 
design, acquisition of data, or analysis and interpretation of data; (2) drafting the 
article or revising it critically for important intellectual content; (3) final approval of the 
version to be published and (4) agreement to be accountable for all aspects of the 
work in ensuring that questions related to the accuracy or integrity of any part of the 
work are appropriately investigated and resolved.  Authors should meet conditions 
1, 2, 3, and 4. 
• 
When a large, multicenter group has conducted the work, the group should identify 
the individuals who accept direct responsibility for the manuscript.  These individuals 
should fully meet the criteria for authorship defined above. 
• 
Acquisition of funding, collection of data, or general supervision of the research 
group, alone, does not justify authorship. 
• 
All persons designated as authors should qualify for authorship, and all those who 
qualify should be listed. 
• 
Each author should have participated sufficiently in the work to take public 
responsibility for appropriate portions of the content. 
All publications (eg, manuscripts, abstracts, oral/slide presentations, book chapters) 
based on this study must be submitted to Amgen for review.  The Clinical Trial 
Agreement among the institution, investigator, and Amgen will detail the procedures for, 
and timing of, Amgen’s review of publications.

Appendix A.  Additional Safety Assessment Information 
Adverse Event Grading Scale 
The Common Terminology Criteria for Adverse Events (CTCAE) is available at the 
following location:  
http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm] 
Drug-induced Liver Injury Reporting & Additional Assessments  
Reporting 
To facilitate appropriate monitoring for signals of DILI, cases of concurrent AST or ALT 
and TBL and/or INR elevation according to the criteria specified in Section 6.5 require 
the following: 
• 
The event is to be reported to Amgen as a serious adverse event within 24 hours of 
discovery or notification of the event (ie, before additional etiologic investigations 
have been concluded) 
• 
The appropriate CRF (eg, Event CRF) that captures information necessary to 
facilitate the evaluation of treatment-emergent liver abnormalities is to be completed 
and sent to Amgen.  
Other events of hepatotoxicity and potential DILI are to be reported as serious adverse 
events if they meet the criteria for a serious adverse event defined in Section 9.2.2.2. 
Additional Clinical Assessments and Observation 
All subjects in whom investigational product(s) or protocol-required therapies is/are 
withheld (either permanently or conditionally) due to potential DILI as specified in 
Table 1 or who experience AST or ALT elevations > 3 x ULN or 2-fold increases above 
baseline values for subjects with elevated values before drug are to undergo a period of 
“close observation” until abnormalities return to normal or to the subject’s baseline 
levels.   
Assessments that are to be performed during this period include:  
• 
Repeat AST, ALT, ALP, bilirubin (total and direct), and INR within 24 hours  
• 
In cases of TBL > 2x ULN or INR > 1.5, retesting of liver tests, BIL (total and direct), 
and INR is to be performed every 24 hours until laboratory abnormalities improve

Testing frequency of the above laboratory tests may decrease if the abnormalities 
stabilize or the investigational product(s) or protocol-required therapies has/have been 
discontinued AND the subject is asymptomatic. 
• 
Initiate investigation of alternative causes for elevated AST or ALT and/or elevated 
TBL.  The following are to be considered depending on the clinical situation: 
− 
Complete blood count (CBC) with differential to assess for eosinophilia 
− 
Serum total immunoglobulin IgG, Anti-nuclear antibody (ANA), Anti Smooth 
Muscle Antibody, and Liver Kidney Microsomal antibody 1 (LKM1) to assess for 
autoimmune hepatitis 
− 
Serum acetaminophen (paracetamol) levels 
− 
A more detailed history of:  
o 
Prior and/or concurrent diseases or illness 
o 
Exposure to environmental and/or industrial chemical agents  
o Symptoms (if applicable) including right upper quadrant pain, 
hypersensitivity-type reactions, fatigue, nausea, vomiting and fever 
o Prior and/or concurrent use of alcohol, recreational drugs and special diets 
o Concomitant use of medications (including non-prescription medicines and 
herbal and dietary supplements), plants, and mushrooms 
− 
Viral serologies 
− 
Creatinine phosphokinase, haptoglobin, lactate dehydrogenase (LDH), and 
peripheral blood smear 
− 
Appropriate liver imaging if clinically indicated 
o Appropriate blood sampling for pharmacokinetic analysis if this has not 
already been collected  
o Hepatology consult (liver biopsy may be considered in consultation with an 
hepatologist) 
o Follow the subject and the laboratory tests (ALT, AST, TBL, INR) until all 
laboratory abnormalities return to baseline or normal or considered stable by 
the investigator.  The “close observation period” is to continue for a minimum 
of 4 weeks after discontinuation of all investigational product(s) and 
protocol-required therapies. 
The potential DILI event and additional information such as medical history, concomitant 
medications and laboratory results must be captured in the corresponding CRFs.

2.2 
Hypotheses and/or Estimations 
The primary statistical hypothesis of the co-primary endpoints is as follows:  
Within each dose frequency, the null hypothesis is that there is no difference in means, 
in the mean percent change from baseline at weeks 10 and 12, or in the percent change 
from baseline at week 12 in LDL-C, between evolocumab and placebo, when used in 
combination with optimal stable background statin therapy in Chinese subjects with 
primary hypercholesterolemia and mixed dyslipidemia. The alternative hypothesis is that 
a mean difference does exist. 
3. 
Study Overview 
3.1 
Study Design 
This is a phase 3, multicenter, double-blind, randomized, placebo-controlled study of 
evolocumab in Chinese subjects with hypercholesterolemia and mixed dyslipidemia. 
Subjects, who have signed the informed consent form (ICF), will have fasting lipids 
measured and all inclusion and exclusion criteria assessed. Subjects should maintain 
their current diet and exercise regimen.  Subjects who, in the opinion of the investigator 
require statin up-titration or dietary adjustment can be rescreened after 1 month.  
Subjects can only be rescreened once. Statins may not be down-titrated with 
subsequent rescreened. Subjects who screen fail due to the LDL-C below the limit for 
eligibility during final screening cannot be rescreened. Baseline statin therapy is 
expected to be continued unchanged throughout the study. Subjects will be randomized 
2:2:1:1 into the following treatment arms: 
 
Evolocumab SC 140 mg Q2W, 
 
Evolocumab SC 420 mg QM, 
 
Placebo SC Q2W, or 
 
Placebo SC QM.  
Randomization will be stratified by entry CV risk (high/very high CV risk vs. not high/very 
high CV risk). 
The overall sample size will be approximately 450 subjects (150 subjects for each 
evolocumab dosing regimen).  The sample size for each placebo will be approximately 
75 subjects. 
Evolocumab and placebo will be administered SC at the study site or in an appropriate 
non-clinic setting (eg, at home) by spring based prefilled autoinjector/pen (AI/Pen). 
Observed, in clinic dosing will occur at day 1, Week 8 (± 3 days) and Week 10 (± 3 days)

Protocol Number:  20150172 
Date:  30 November 2020

CONFIDENTIAL 
 
 
(as applicable). The dose frequencies of Q2W and QM will not be blinded but the identity 
of investigational product (evolocumab or matching SC placebo) will be blinded. 
Subjects must tolerate a SC injection of placebo with a prefilled AI/Pen device to be 
used during the study prior to randomization. 
All central laboratory results of ApoA1, ApoB, lipoprotein(a), PCSK9, hsCRP will be 
blinded from day 1 until unblinding of the clinical database and will not be reported to the 
investigator.  Central laboratory results of the lipid panel will be blinded from day 1 until 
unblinding of the clinical database and will not be reported to the investigator.  
Investigators should not perform non protocol testing of these analytes during a subject’s 
study participation and until at least 12 weeks after last investigational product 
administration, or the subject’s end of study (EOS), whichever is later. 
Approximately 40 sites in China will participate in this study.  Treatment and follow-up 
period will be 12 weeks with an additional phone call or other subject contact at week 14 
for subjects receiving investigational product Q2W. The EOS for subjects on QM 
investigational product is at the week 12 visit which must be at least 30 days post last 
dose of investigational product.  The EOS for subjects on Q2W investigational product is 
a telephone call from the site at week 14 (and at least 30 days post last dose of 
investigational product) for any potential adverse events, adverse device effects (ADEs), 
disease related events (DREs) and serious adverse events. Subjects will be encouraged 
to complete all planned visits regardless of their adherence to investigational product 
administration.  
3.2 
Sample Size 
The sample size for this study has been considered to meet the requirement from 
regulatory authority (Drug Registration Regulation No 28; Oct 2007). 
The planned total sample size is 450 subjects (150 randomized to evolocumab SC 
140 mg Q2W, 150 randomized to evolocumab SC 420 mg QM, 75 randomized to 
placebo Q2W and 75 randomized to placebo QM). The primary analysis will require the 
tests of each co-primary endpoint to be significant at level of 0.05. The sample size 
should provide adequate power to determine the superiority of evolocumab (either Q2W 
or QM) relative to respective placebo (Q2W or QM) as measured by the co-primary 
endpoints. 
From the phase 3 study 20120122 and phase 2 study 20110155, the mean treatment 
effect of evolocumab 140 mg Q2W and 420 mg QM compared to placebo in percent

change from baseline in LDL-C at week 12 was at least -50.3%, with the smallest 
treatment effect of -44.6% estimated from 95% confidence intervals. For the co-primary 
endpoint of mean percent change from baseline in LDL-C at weeks 10 and 12, the mean 
treatment effect of evolocumab 140 mg Q2W and 420 mg QM compared to placebo was 
at least -62.4%, with the smallest treatment effect of -57.2% estimated from 95% 
confidence intervals. 
The assumed treatment effect of evolocumab in LDL-C reduction is 40%, with a common 
SD of 25%. As the co-primary endpoints are correlated, the planned sample size will 
provide approximately at least 98% (99% x 99%) power in testing the superiority of each 
evolocumab dosing regimen over placebo on the co-primary endpoints, assuming a 10% 
drop out rate. 
Since the testing statistics from Q2W and QM groups are independent, there is a 96% 
chance (98% x 98%) to show the superiority of both evolocumab dosing regimens over 
placebo. 
The power calculation is derived using SAS Enterprise Guide version 6.1. 
Seventeen subjects who were enrolled in the study will be excluded from all 
analyses (both efficacy and safety) because they would require additional Human 
Genetic Resource Administration office of China (HGRAC) approvals, as follows: 
 
According to the Administrative Regulations on Human Genetic Resources 
of the People's Republic of China, effective on 01 July 2019, if a study screens 
 500 Chinese subjects, the study must complete the HGRAC sample collection 
application.  Twelve subjects in Study 20150172 were enrolled after screening had 
reached 500; therefore, these 12 subjects will be excluded from the analyses.   
 
Under this same regulation, foreign-invested hospitals cannot participate in 
this application.  Suzhou Kowloon Hospital, which enrolled 5 subjects in Study 
20150172, is a Hong Kong-invested hospital, according to Implementation

Other Study Related Definitions 
Actual Treatment Group  
A subject’s actual treatment group is the randomized treatment group, unless the subject 
receives treatment throughout the study that is different than the randomized treatment 
group assignment, in which case the actual treatment group is the treatment received. 
Investigational Product (IP)  
SC IP includes Evolocumab SC 140 mg Q2W, Evolocumab SC 420 mg QM and their 
corresponding SC placebo. 
IP Exposure Period in Months  
For each Q2W subject:  
IP Exposure Period = [min (Last SCIPD + 14 days, EOS Date) - First SCIPD + 1]/ 365.25 
* 12  
For each QM subject:  
IP Exposure Period = [min (Last SCIPD + 28 days, EOS Date) - First SCIPD +1] / 365.25

investigational product” equal to “No” or missing on the Events eCRF, and up to 
30 days after the last dose of investigational product or EOS date, whichever is earlier. 
Treatment Emergent Serious Adverse Event (TESAE) 
Treatment-emergent adverse events (as defined above) that are indicated as serious on 
the Events eCRF. 
Reflexive Approach for LDL-C and VLDL-C 
For all analyses related to LDL-C and VLDL-C, unless specified otherwise, the following 
reflexive approach will be used. When calculated LDL-C is less than 40 mg/dL or 
triglycerides > 400 mg/dL, the UC LDL-C value from the same blood sample will be used 
instead of calculated LDL-C and the UC VLDL-C value from the same blood sample will 
be used instead of calculated VLDL-C, if available. 
Achievement of LDL-C < 70 mg/dL  
A subject has achievement of LDL-C < 70 mg/dL if the post-baseline LDL-C value is less 
than 70 mg/dL. If the value is missing, the subject is considered without the 
achievement. 
Mean achievement of LDL-C < 70 mg/dL at weeks 10 and 12 is defined using the mean 
of non-missing LDL-C values at those two timepoints (if one is missing, mean equals the 
available one). If both the values at weeks 10 and 12 are missing, the subject is 
considered without the achievement. 
LDL-C response (50% reduction from baseline) 
A subject has a response of 50% reduction from baseline in LDL-C, if the LDL-C percent 
change from baseline value is less than or equal to -50%. If the value is missing, the 
subject is considered without the response when statistical inference is performed. 
Mean response of LDL-C 50% reduction at weeks 10 and 12 is defined using the mean 
of non-missing LDL-C percent change from baseline values at those two timepoints (if 
one is missing, mean equals the available one). If both the values at weeks 10 and 12 
are missing, the subject is considered without the response when statistical inference is 
performed.

Analysis Sets 
6.1 
Full Analysis Set 
The full analysis set (FAS) includes all randomized subjects who received at least 
1 dose of IP excluding the 17 subjects that require additional Human Genetic 
Resource Administration office of China approval (Refer Section 3.2 for details). In 
efficacy analysis, subjects will be analyzed according to their randomized treatment 
group assignment.  
6.2 
Safety Analysis Set 
Safety Analysis Set is same as the Full Analysis Set. For safety analyses, subjects will 
be grouped according to their actual treatment group (as defined in Section 5.3). 
6.3 
Study-specific Analysis Sets 
Completers Analysis Set 
The completer analysis set (CAS) includes subjects in the FAS who adhered to the 
scheduled IP regimen in the double-blind treatment period and have observed value for 
the co-primary endpoints.  
7. 
Planned Analyses 
7.1 
Interim Analysis and Early Stopping Guidelines 
No interim analysis is planned for this study. 
7.2 
Primary Analysis 
The primary analysis will be performed, when all subjects have either completed the 
study, or have early terminated from the study. At that time, the database will be 
cleaned, processed, locked and a snapshot will be taken; the study will also be 
unblinded for analyses. Based on the snapshot, efficacy and safety analyses will 
be performed.

database and central lab data (outside of RAVE database). The database will be 
subjected to edit checks outlined in the Data Management Plan (DMP).  Additional 
details will be provided in DMP and Data Acquisition Requirements Specifications 
(DARS). 
8.3 
Handling of Missing and Incomplete Data 
8.3.1 
Patterns of Missing Data 
Subjects may be missing specific data points for various reasons. In general, data may 
be missing due to a subject’s early withdrawal from study, a missed visit, or 
non-evaluability of a data point or an endpoint at a particular point in time. All attempts 
will be made to capture missing or partial data for this trial prior to the database lock.  
8.3.2 
Missing Lipid Measurements  
For efficacy endpoints, where the analysis method is repeated measures linear effects 
model, missing lipid measurements will not be imputed. The handling of missing LDL-C 
response (50% reduction of LDL-C from baseline) and achievement of target LDL-C 
< 70 mg/dL is provided in Section 5.3. Sensitivity analysis will be performed on the 
co-primary endpoints to evaluate the robustness of the missing at random assumption, 
used in the repeated measures linear effects model as described in Section 9.5.1.1.  
8.3.3 
Handling of Incomplete Dates  
Adverse events and concomitant medications with completely or partially missing start 
dates will be queried. If after the query is resolved, the date is still incomplete with year 
only or year and month only, the start date will be imputed as described as below.

8.4 
Detection of Bias 
This study has been designed to minimize potential bias by the use of randomization of 
subjects into treatment groups and the use of blinding. Other factors that may bias the 
results of the study include:  
 
Major protocol deviations likely to impact the analysis and interpretation of the 
efficacy endpoints. 
 
Subject level unblinding before final database lock and formal unblinding. 
Important protocol deviations likely to impact the analysis and interpretation of the 
efficacy endpoints will be tabulated in the Clinical Study Report (CSR).  
Any unblinding of individual subjects prior to formal unblinding of the study will be 
documented in the CSR. The impact of such unblinding on the results observed will be 
assessed. Data from subjects whose treatment assignments are unblinded prior to 
formal unblinding will be listed. The timing and reason for unblinding will be included in 
these listings.  
Additional sensitivity and/or supplementary analyses may be included to assess the 
impact of potential biases on the co-primary endpoints. If any sensitivity analyses are 
required to evaluate potential biases in the study’s conclusions, then the sources of the 
potential biases and results of the sensitivity and/or supplementary analyses will be 
documented in the CSR. 
8.5 
Outliers 
Various methods, including univariate summaries, histograms, scatter plots, box plots, 
and line graphs, may be used to identify outliers in key safety and efficacy variables. 
Extreme data points will be identified during the blinded review of the data prior to 
database lock. Such data points will be reviewed with clinical data management to 
ensure accuracy. The primary analyses will include outliers in the data. Sensitivity 
analyses may be undertaken if extreme outliers for a variable are observed. 
8.6 
Distributional Characteristics 
Distributional assumptions for the primary and secondary co-endpoints will be assessed. 
If the assumptions are not met, then alternative methods will be utilized. The use of 
alternative methods will be fully justified in the CSR. 
8.7 
Validation of Statistical Analyses 
Programs will be developed and maintained and, output will be verified in accordance 
with current risk-based quality control procedures.

Statistical Methods of Analysis 
9.1 
General Considerations 
The efficacy and safety analyses will be performed on the FAS. Unless specified 
otherwise, the FAS will be the default analysis set in this study and data will be 
summarized by randomized treatment group using the analysis window specified in 
Table 12-1. Analyses will be performed separately by each dose frequency (Q2W and 
QM) unless specified otherwise.  
Subject disposition, demographics, baseline characteristics and exposure to IP will be 
summarized by treatment group.  Summary statistics for continuous variables will 
include the number of subjects, mean, median, SD or standard error, minimum, and 
maximum. For categorical variables, the frequency and percentage will be given.  
Methods of handling missing data for efficacy endpoints will be described below. Missing 
data will not be imputed for safety endpoints.  
Multiplicity Adjustment Method 
The analyses of Q2W and QM will be performed as 2 independent experiments. To 
preserve the familywise error rate at 0.05 within each independent experiment (Q2W 
and QM), methods of adjusting for multiplicity due to multiple estimands (co-primary and 
secondary efficacy estimands) within each dose frequency are described in the diagram 
below (Figure 9-1).

Figure 9-1.  Multiplicity Adjustment Methods 
 
Testing of each estimand pair will result in a single p-value, and for co-secondary 
estimands these p-values will then be used in the Hochberg procedure. The following 
method will be used to preserve the family wise error rate for the co-primary and 
secondary estimands for testing within each dose frequency: 
1. If the treatment effect from the primary analysis of the co-primary estimands are 
both significant at a significance level of 0.05, statistical testing of the tier 1 
secondary efficacy estimands will follow the Hochberg procedure at a 
significance level of 0.005 (Hochberg, 1988) 
2. If all tier 1 secondary efficacy estimands are significant, the tier 2 secondary 
efficacy estimands will be tested using the Hochberg procedure at a significance 
level of 0.05.  
3. If not all tier 1 secondary efficacy estimands are significant, the tier 2 secondary 
efficacy estimands will be tested using the Hochberg procedure at a significance 
level of 0.045 (Wiens, 2003). 
Unless specified otherwise, all other hypothesis testing will be 2-sided with a significance 
level of 0.05.

Important Protocol Deviations 
Important Protocol Deviations (IPDs) categories are defined by the study team before 
the first subject’s initial visit and updated during the IPD reviews throughout the study 
prior to database lock.  These definitions of IPD categories, subcategory codes, and 
descriptions will be used during the course of the study.  Eligibility deviations are defined 
in the protocol. 
The number of subjects meeting Protocol Deviations due to COVID-19 will be 
summarized. A Protocol Deviations listing of subjects impacted due to COVID-19 
will also be provided.

Demographic and Baseline Characteristics 
Demographic (ie, age, geriatric age group [< 65, >= 65 and >= 75], sex, race, ethnicity) 
and baseline disease characteristics (cardiovascular medical history and lipid-regulating 
medication) will be summarized by treatment group and overall using descriptive 
statistics. If multiple races have been reported for a subject, the subject will be 
categorized as multiple race.

9.5.1 
Analyses of Primary Efficacy Endpoint(s) 
To assess the co-primary endpoints as described in the co-primary estimands a 
repeated measures linear effects model including all observed values (on and off 
treatment) will be used on the FAS in each dose frequency to compare the efficacy of 
evolocumab with placebo.  The repeated measures model will include terms for 
treatment group, stratification factor, scheduled visit and the interaction of treatment with 
scheduled visit. Missing values will not be imputed for primary analysis.  
To account for the repeated LDL-C measurements within a subject across the visits, the 
repeated measures linear effects model will use an unstructured covariance.  
Multiplicity adjustment procedures are defined in Section 9.1. 
9.5.1.1 
Sensitivity Analyses of Co-primary Endpoints 
To evaluate the robustness of the analysis results, sensitivity analyses will be performed 
as follows: 
 
Multiple imputation assuming MAR to handle missing primary variables  
 
It will be assumed that the missing percent change values will be normally 
distributed with a mean 0 and a variance-covariance matrix the same as the 
observed variance-covariance matrix from subjects in the placebo group and 
have missing endpoint data. 
 
If there are at least 25 subjects in each treatment group who discontinue IP but 
have non-missing endpoint data, an additional multiple imputation will be carried 
out utilizing the information from these subjects to impute the missing data for 
subjects who discontinue IP and have missing endpoint data. 
 
An additional sensitivity analysis will be performed to evaluate the impact of 
COVID-related out of window visits. Primary analysis will be repeated using 
FAS. The subjects meeting protocol deviation code 953 (out-of-window visit) 
will use the analysis window defined in Table 12-2 and the remaining subjects 
will use the analysis window defined in Table 12-1 (ie, same visit window as 
the primary analysis). 
Supplementary analysis 
 
In addition to the sensitivity analysis, the primary analysis will be repeated using the 
CAS (described in Section 6.7) acknowledging there are limitations and biases with 
this analysis.  A non-parametric analysis may also be performed if the assumption of 
normality is violated. 
9.5.1.2 
Covariate and Subgroup Analyses of Co-primary Endpoints 
In addition to the primary analysis, covariate-adjusted analyses of the co-primary 
efficacy estimands will be performed as supportive analyses using the baseline 
covariates in Section 4.2, one at a time, in the primary model used in the primary 
analyses as appropriate.

Subgroup analyses on the co-primary efficacy estimands will be conducted using the 
subgroups specified in Section 4.2. Treatment effect differences among subgroups, 
which represent subgroup by treatment interactions, will be estimated and tested based 
on statistics from the subgroup repeated measures models.  
For covariate and subgroup analyses, the stratification factor from the eCRF will be 
used. Differences in stratum assignment between data collection via IVRS and eCRF will 
be tabulated. 
9.5.2 
Analyses of Secondary Efficacy Endpoint(s) 
The statistical model and testing of the tier 1 secondary efficacy endpoints as described

of the co-primary estimands. The secondary estimands of achievement of target LDL-C 
< 70 mg/dL and LDL-C response of ≥ 50% reduction from baseline will be analyzed 
using the Cochran-Mantel Haenszel (CMH) test adjusted by the stratification factor. 
Analyses of the tier 2 secondary efficacy estimands will use the same analysis model as 
the tier 1 estimands, Refer to Section 9.1 and Figure 9-1 for multiplicity adjustment for 
multiple tier 1 and tier 2 secondary endpoints.

Changes From Protocol-specified Analyses 
Eighteen subjects who were enrolled in the study will be excluded from all 
analyses (both efficacy and safety) because they would require additional Human 
Genetic Resource Administration office of China (HGRAC) approvals, as follows: 
* 
According to the Administrative Regulations on Human Genetic Resources 
of the People's Republic of China, effective on 01 July 2019, if a study screens 
500 Chinese subjects, the study must complete the HGRAC sample collection 
application.  Thirteen subjects in Study 20150172 were enrolled after screening 
had reached 500; therefore, these 13 subjects will be excluded from the analyses. 
 
Under this same regulation, foreign-invested hospitals cannot participate in 
this application.  Suzhou Kowloon Hospital, which enrolled 5 subjects in Study 
20150172, is a Hong Kong-invested hospital, according to Implementation

Appendix C.  Framingham Risk Score 
The method to calculate Framingham Risk Score is described below. 
The  coefficients given in the two tables below are used to compute a linear function. 
The latter is corrected for the averages of the participants’ risk factors (mean) from the 
Framingham study, and the subsequent result is exponentiated and used to calculate a 
10-year probability of HCHD after insertion into a survival function (Wilson et al). 
The calculation is different for men and women and uses the following coefficients i, 
where i represent each of the independent variables.  The values below are from the 
Framingham heart study (http://www.framinghamheartstudy.org/risk/hrdcoronary.html).   
t_chol  total cholesterol, hdl  HDL-C, sbp  systolic blood pressure, trt_htn  treatment 
for hypertension (if sbp  120), smoker  current smoker

For Patient level parameters (xi for i in 1:13), multiply that patient’s value by the 
appropriate coefficient (i) to get the patient-parameter value (zi) then sum up the 
patient-parameter value of all the relevant parameters (z1, z2,…,z13) to get the patient 
sum (y). Then, the estimated 10-year risk of first hard ASCVD is calculated as 1 minus 
the baseline survival, raised to the power of the exponent of the patient sum minus the 
Mean Value. Written as an equation this can be expressed as: 
𝑦∑
𝛽𝑖𝑥𝑖
𝑛
𝑖1
 
Estimated 10 −year risk of a first hard ASCVD1 −𝑏𝑒𝑦−𝑎 
*N/A means that particular parameter is not included in the calculation for that subgroup 
(can be thought of as i being equal to 0.)  
Note: aCohort Constant, bBaseline Survival, and i Cohort Specific Parameter 
Coefficient are cohort specific values (eg, African American Woman), and xi are patient 
specific values. 
Example: White 43-year-old woman with Total-cholesterol211mg/dL, HDL-C52mg/dL, 
untreated systolic BP117 mm Hg, smoker without diabetes. For this patient 8 and 10 
are not used due to being in the white female cohort. 7 is also unused as they have 
untreated Systolic BP. x111 and  
x12ln(age)*1 as they are a smoker and x13, x140 as they do not have diabetes. In this 
case a-29.18, b0.9665 and i will be selected from the same column as a and b. The 
Final value this gives is  
1 −0.9665exp(−27.546−(−29.18))0.026 or 2.6 risk of hard ASCVD in 10-years

Analytical Study Week Assignments  
Analytical windows will be used to assign parameter measurements to study weeks. The 
algorithm is provided below. 
Selected endpoints will be summarized by scheduled study visits in descriptive analyses. 
Since the actual visits may not exactly coincide with their scheduled visit day, the actual 
visit day is mapped to the study visit generally by non-overlapping consecutive intervals 
covering the entire time continuum. The mapping intervals for all distinct schedules are 
summarized in the following table:

Handling multiple records assigned to an analytical study week:  
If there is more than one record in a study week interval, the analytical record for that 
specific study week will be defined as the record closest to the scheduled visit day of 
that specific study week (7 x study week + 1). If two records are equidistant from the 
scheduled day, then the earlier record will be chosen. If there are multiple records on the 
same day, the last record will be used.
