Brief summary:
This is a multicenter, open-label extension (OLE) study designed to assess the extended long-term safety of evolocumab in subjects who have completed the FOURIER trial (Study 20110118). Approximately 1600 subjects will be enrolled in this study. This study will continue for 260 weeks (approximately 5 years).

Detailed description:
This is a multicenter, open-label extension (OLE) study designed to assess the extended long-term safety of evolocumab in subjects who have completed the FOURIER trial (Study 20110118). FOURIER is a randomized placebo-controlled study of evolocumab, in patients with clinically evident atherosclerotic CVD on stable effective statin therapy. Subjects at sites participating in FOURIER OLE (Study 20160250) who are eligible and have signed the FOURIER OLE informed consent will be enrolled after completion of FOURIER.

The FOURIER OLE study requires laboratory assessments at day 1, week 12, and thereafter approximately every 6 months from day 1; the corresponding blood samples will be processed using a central laboratory.

Upon enrollment in FOURIER OLE study, subjects will receive evolocumab 140 mg every 2 weeks (Q2W) or 420 mg monthly (QM) according to their preference. Frequency and corresponding dose of administration can be changed at any scheduled time point where evolocumab is supplied to the subject, provided the appropriate supply is available. It is recommended that subjects continue the same background lipid-lowering therapy (LLT), including statin, as taken during FOURIER.

This study will continue for 260 weeks (approximately 5 years). Subjects ending administration of evolocumab should continue study assessments until the end of study. All subjects will be followed and complete procedures/assessments from enrollment through the date of study termination unless the subject has withdrawn consent, irrespective of whether the subject is continuing to receive treatment.

All deaths and cardiovascular events of interest will be reviewed by an independent external Clinical Events Committee (CEC), using standardized definitions.

Protocol Synopsis 
Title:  A Multicenter, Open-label, Single-arm, Extension Study to Assess Long-term Safety of 
Evolocumab Therapy in Subjects With Clinically Evident Cardiovascular Disease in Selected 
European Countries 
Study Phase:  3b 
Indication:  Dyslipidemia 
Primary Objective:  To describe the safety and tolerability of long-term administration of 
evolocumab.  
Secondary Objective(s):  The secondary objectives are to describe the effects of long-term 
administration of evolocumab on low-density lipoprotein cholesterol (LDL-C) levels and to 
describe the effects of long-term administration of evolocumab in subjects achieving an LDL-C 
level < 40 mg/dL (1.03 mmol/L). 
Exploratory objectives are provided in Section 1.3. 
Hypothesis:  The primary clinical hypothesis is that long-term exposure of evolocumab will be 
safe and well tolerated in subjects with clinically evident atherosclerotic cardiovascular disease 
(CVD). 
Primary Endpoint:  The primary endpoint is the subject incidence of adverse events. 
Secondary Endpoints:  The secondary endpoints are the percent change of LDL-C from 
baseline at each scheduled visit and the achievement of an LDL-C < 40 mg/dL (1.03 mmol/L) at 
each scheduled visit. 
Exploratory endpoints are provided in Section 10.1.1.3. 
Study Design:  This is a multicenter, open-label extension (OLE) study designed to assess the 
extended long-term safety of evolocumab in subjects who have completed the FOURIER trial 
(Study 20110118).  FOURIER is a randomized placebo-controlled study of evolocumab, in 
patients with clinically evident atherosclerotic CVD on stable effective statin therapy.  Subjects at 
sites participating in FOURIER OLE (Study 20160250) who are eligible and have signed the 
FOURIER OLE informed consent will be enrolled after completion of FOURIER. 
The FOURIER OLE study requires laboratory assessments at day 1, week 12, and thereafter 
approximately every 6 months from day 1; the corresponding blood samples will be processed 
using a central laboratory.   
Upon enrollment in FOURIER OLE study, subjects will receive evolocumab 140 mg every 
2 weeks (Q2W) or 420 mg monthly (QM) according to their preference.  Frequency and 
corresponding dose of administration can be changed at any scheduled time point where 
evolocumab is supplied to the subject, provided the appropriate supply is available.  It is 
recommended that subjects continue the same background lipid-lowering therapy (LLT), including 
statin, as taken during FOURIER. 
This study will continue for 260 weeks (approximately 5 years).  Subjects ending administration of 
evolocumab should continue study assessments until the end of study.   
All subjects will be followed and complete procedures/assessments from enrollment through the 
date of study termination unless the subject has withdrawn consent, irrespective of whether the 
subject is continuing to receive treatment.  All deaths and cardiovascular events of interest will be 
reviewed by an independent external Clinical Events Committee (CEC), using standardized 
definitions. 
Sample Size:  Approximately 1600 subjects will be enrolled in this study. 
Summary of Subject Eligibility Criteria:  Subjects must have completed FOURIER 
(Study 20110118) while still receiving assigned investigational product and provided informed 
consent for this FOURIER OLE (20160250) study.  Eligible subjects may not be currently 
receiving treatment in another investigational device or drug study, or have ended treatment on 
another investigational device or drug study(ies) within less than 4 weeks.  Women cannot be

pregnant or breastfeeding or planning to become pregnant or planning to breastfeed during 
treatment with evolocumab and within 15 weeks after the end of treatment with evolocumab.  
Women of childbearing potential must be willing to use an acceptable method(s) of effective birth 
control during treatment with evolocumab and for an additional 15 weeks after the end of 
treatment with evolocumab. 
For a full list of eligibility criteria, please refer to Section 4.   
Investigational Product 
Amgen Investigational Product Dosage and Administration:  Evolocumab will be 
administered using a handheld mechanical (spring-based) prefilled 1.0 mL auto-injector/pen 
(AI/pen) or an on-body electromechanical 3.5 mL personal injector (PI). 
Evolocumab will be administered 140 mg subcutaneous (SC) Q2W (1 administration by prefilled 
AI/pen) or 420 mg SC QM (3 administrations by prefilled AI/pen or 1 administration by PI). 
Subjects will choose whether to initiate treatment at the Q2W or QM schedule and will have the 
opportunity to switch between evolocumab Q2W and QM at any scheduled time point where 
evolocumab is supplied to the subject, provided the appropriate supply is available.  Subjects who 
choose QM treatment will initiate treatment using the PI, provided the appropriate supply is 
available.  If the PI is not available, then the AI/pen may be used.  Subjects will have the 
opportunity to switch between the AI/Pen and PI, at any scheduled time point where 
evolocumab is supplied to the subject, provided the appropriate supply is available. 
Non-investigational Product 
Non-Amgen Non-investigational Product Dosage and Administration:  It is recommended 
that subjects continue the same background LLT, including statin, as taken while in FOURIER.  
Background LLT will not be provided by Amgen. 
Procedures:  Mandatory study visits will occur at day 1, week 12 and thereafter approximately 
every 6 months from day 1.  Evolocumab resupply visits will be scheduled quarterly (every 
12 weeks).  The last resupply of evolocumab will occur 12 weeks after the week 240 visit.  
Evolocumab will be supplied directly to the site.  The method of resupply will be determined 
based on local regulations as well as available infrastructure.  Assessments and procedures 
include vital signs; physical examination; body weight; assessment of concomitant therapy, 
adverse events, adverse device effects, serious adverse events, and disease-related events; 
laboratory assessments, including fasting lipid panel, apolipoprotein A1, apolipoprotein B, and 
lipoprotein(a); serum pregnancy testing (women of childbearing potential only); and evolocumab 
administration.  If evolocumab is administered at the site, the administration by SC injection will 
be done after blood draw and vital sign procedures have been completed. 
For a full list of study procedures, including the timing of each procedure, please refer to 
Section 7 and the Schedule of Assessments (Table 3).   
Statistical Considerations:  The primary and secondary endpoints will use the OLE safety 
subset (OLE study only) which includes all subjects who received at least 1 dose of open-label 
evolocumab in the OLE study. 
Statistical analyses in this open-label study are descriptive in nature.  No statistical inference or 
missing value imputation is planned.  No formal hypothesis will be tested in this study, unless 
specified otherwise, the baseline value is defined as the subject’s baseline value from the parent 
study (FOURIER).  All analyses will be performed on the OLE safety analyses set.  The primary 
analysis of all primary, secondary, and exploratory endpoints will use data from the OLE study 
only.  Additional analyses combining the data from the OLE study and FOURIER study will be 
performed as applicable.  For all endpoints, results will be summarized by the randomized 
treatment group from the FOURIER study and overall, unless specified otherwise. 
Exposure-adjusted subject incidence rates of all treatment-emergent adverse events, serious 
adverse events, fatal adverse events, adverse events leading to withdrawal from evolocumab, 
device-related adverse events, and disease-related events will be tabulated for the overall OLE 
study period.  These events will also be presented by yearly subject exposure time intervals.  All 
adverse event summaries for the primary analysis of the primary endpoint will include all

treatment-emergent events reported on the Event electronic case report form (eCRF), 
including CEC reviewed events and disease related events.  All CEC reviewed events will be 
reported. 
Adverse event data from the OLE study will also be combined with FOURIER study data as an 
additional analysis and positively reviewed events will not be included in the adverse event 
analysis to remain consistent with FOURIER adverse event reporting. 
Summary statistics of the secondary endpoints (percent change of LDL-C from baseline and 
achieving an LDL-C < 40 mg/dL) will be provided.   
For a full description of statistical analysis methods, please refer to Section 10.

BACKGROUND AND RATIONALE 
2.1 
Cardiovascular Disease 
Collectively, cardiovascular diseases (CVD) are regarded as a world-wide epidemic; and 
though over the last 2 decades CVD mortality has declined (primarily in developed 
countries), it still represents the leading cause of death and disability in the world, as well 
as over 10% of the global total disease burden.  In 2008, the World Health Organization 
(WHO) estimated 57 million deaths world-wide, of which 36 million were due to 
non-communicable causes.  CVD accounted for over 17 million of these deaths, nearly 
80% of which were due to heart attacks and strokes alone (responsible for 7.3 million 
and 6.2 million deaths, respectively). 
A large proportion of CVD is preventable, and the investment in prevention measures 
has been regarded as the most sustainable solution for dealing with the CVD epidemic.  
Elevated cholesterol is among the leading risk factors for cardiovascular deaths (sixth), 
with an estimated prevalence of 39% globally among all adults (even greater in 
high-income countries).  Cardiovascular disease perhaps represents the single leading 
threat to the health of the world; the unmet medical need in this arena is immense 
(World Health Organization, 2011).

Dyslipidemia is a major modifiable risk factor for the development of CVD.  It is 
estimated that approximately 100 and 34 million Americans have a total cholesterol in 
excess of 200 mg/dL (approximately 5.2 mmol/L) and 240 mg/dL (approximately 
6.2 mmol/L), respectively.  In Europe, up to 50% of the population aged 35 to 64 years 
has total cholesterol > 250 mg/dL (6.5 mmol/L) (Tolonen et al, 2005).  This high 
prevalence of dyslipidemia translates into a significant cardiovascular morbidity and 
mortality, as described above.  Dyslipidemia is associated with more than 50% of the 
global cases of coronary heart disease and more than 4 million deaths per year 
worldwide. 
To decrease the morbidity and mortality associated with CVD, over 50 million patients in 
the United States, Europe, and Japan are currently treated with dyslipidemia therapies.  
The rationale for treatment of dyslipidemia, particularly elevated LDL-C, extends from 
extensive clinical trial 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 
(Kannel, 1995; Kannel et al, 1979; Kannel et al, 1974).  The most recent 
Cholesterol Treatment Trialists’ Collaboration (2010) meta-analysis which included 
21 randomized controlled trials of statin versus control involving nearly 170 000 patients 
showed that for every approximately 1 mmol/L reduction of LDL-C, there was an 
approximately 20% reduction in the risk of major vascular events (coronary death, 
non-fatal myocardial infarction [MI], coronary revascularization, or stroke).  Importantly, 
this meta-analysis, which also evaluated 5 trials that compared more versus less 
intensive statin therapy, did not find a LDL-C threshold for risk reduction; additional 
vascular risk reduction is possible in patients with low LDL-C.  The opportunity for further 
cardiovascular risk reduction is also consistently seen in the numerous primary and 
secondary prevention studies where subjects are treated with statins to their LDL-C goal, 
the results of which have manifested in durable, dramatic changes in medical practice 
and have consequently saved millions of lives. 
Despite achieving their LDL-C goals, approximately two-thirds of these patients on lipid 
reduction therapy still have cardiovascular events (Libby and Theroux, 2005).  While it is 
unlikely that this residual risk is entirely due to the additional LDL-C reduction needed 
beyond the LDL-C goal articulated in recent treatment guidelines (Grundy et al, 2004; 
National Cholesterol Education Program, 2002), Cholesterol Treatment Trialists’ 
Collaboration (2010) data suggest that novel agents that are capable of providing

additional LDL-C lowering on top of statins may further reduce cardiovascular morbidity 
and mortality.  Furthermore, some individuals are intolerant to statin therapy and cannot 
achieve their respective LDL-C goals (eg, Bruckert et al, 2005; Franc et al, 2003).  
Non-statin treatment options are currently available (eg, ezetimibe, bile acid 
sequestrants, plant stanols, niacin) to lower LDL-C but their potency is limited, such that 
LDL-C reductions occur on the order of 15% to 20%. 
Recently, the IMPROVE-IT study evaluated cardiovascular outcomes (cardiovascular 
death, MI, hospital admission for unstable angina [UA], or coronary revascularization) for 
ezetimibe combined with a statin, compared with a statin alone, in approximately 
18 000 subjects who had been hospitalized for ST segment elevation myocardial 
infarction (STEMI), or non-STEMI or UA, less than 10 days before enrollment 
(Cannon et al, 2015).  At 1 year, mean LDL-C was 70 mg/dL with a statin alone and 
53 mg/dL with ezetimibe combined with a statin (a 24% reduction in LDL-C).  Over the 
duration of the study, the addition of ezetimibe to a statin significantly reduced the event 
rate for the primary combined endpoint from 34.7% to 32.7% (p = 0.016).  Reductions in 
individual event rates included a 21% relative risk reduction for ischemic stroke and 
13% relative risk reduction for MI.  Thus, despite the fact that mean LDL-C with a statin 
alone was 70 mg/dL, a level that is often used as a goal for lipid-lowering therapy (LLT), 
significant additional cardiovascular benefit was obtained by lowering LDL-C further with 
the addition of the non-statin therapy, ezetimibe.  
Considering the remaining cardiovascular risk despite the availability of statin therapy 
and given that non-statin treatment options have modest efficacy and/or are poorly 
tolerated (niacin and bile acid sequestrants), 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.  This need is especially evident 
among individuals at high risk for future cardiovascular events; namely, those who have 
already suffered from a MI, non-hemorrhagic stroke, or coronary or peripheral arterial 
revascularization procedure or amputation due to atherosclerotic disease.   
Evolocumab has demonstrated consistent, significant, and durable reduction in LDL-C 
with favorable effects on other lipid parameters across a robust clinical development 
program in more than 6000 subjects with primary hyperlipidemia and mixed 
dyslipidemia.  In these studies, evolocumab reduced LDL-C by approximately 55% 
to 75% compared with placebo and by approximately 35% to 45% compared with 
ezetimibe.  In subjects with homozygous familial hypercholesterolemia, evolocumab

reduced LDL-C by approximately 30% compared with placebo.  Reduction of LDL-C was 
maintained with long-term treatment.  The adverse event profile for evolocumab was 
similar overall to that of the control groups, including placebo.  Extensive analyses have 
not identified major safety issues, including for low LDL-C, with evolocumab therapy. 
Recently published data suggests potential for evolocumab to have beneficial effects on 
outcomes of CVD (Sabatine et al, 2015).  This could potentially be confirmed with the 
results of FOURIER, the clinical outcomes study with evolocumab.  
2.2 
Amgen Investigational Product Background 
Recycling of the hepatic cell surface low-density lipoprotein receptor (LDLR) plays a 
critical role in regulating serum LDL-C levels.  Proprotein convertase subtilisin/kexin 
type 9 (PCSK9) binds to the LDLR and downregulates hepatic cell surface LDLR, which, 
in turn, leads to increased levels of circulating LDL-C.  Humans with PCSK9 
loss-of-function mutations have cholesterol levels lower than normal and reduced 
incidence of coronary heart disease (Abifadel et al, 2003).  Evolocumab is a fully human 
monoclonal immunoglobulin G2, developed at Amgen Inc., that specifically binds to 
PCSK9 preventing its interaction with the LDLR.  The inhibition of PCSK9 by 
evolocumab leads to increased LDLR expression and subsequent decreased circulating 
concentrations of LDL-C. 
Refer to the specific section of the Evolocumab (AMG 145) Investigator’s Brochure for 
additional information related to the physical, chemical, and pharmaceutical properties 
and formulation(s). 
2.3 
Rationale 
This 5-year open-label extension (OLE) study is being conducted to provide additional 
safety data on the long-term administration of evolocumab.  These additional safety data 
include the long-term effects of LDL-C < 40 mg/dL (< 1.03 mmol/L).  A total of 
approximately 1600 subjects will be enrolled. 
2.4 
Clinical Hypothesis 
The clinical hypothesis is that long-term exposure of evolocumab will be safe and well 
tolerated in subjects with clinically evident atherosclerotic CVD. 
3. 
EXPERIMENTAL PLAN 
3.1 
Study Design 
This is a multicenter, OLE study designed to assess the extended long-term safety of 
evolocumab in subjects who have completed the FOURIER (Study 20110118) trial.

FOURIER is a randomized, placebo-controlled study of evolocumab, in patients with 
clinically evident atherosclerotic CVD on stable effective statin therapy.  After signing the 
informed consent, subjects should be enrolled within 7 days.  Subjects at sites 
participating in FOURIER OLE who are eligible and have signed the FOURIER OLE 
informed consent will be enrolled after completion of FOURIER.   
The FOURIER OLE study requires laboratory assessments at day 1, week 12, and 
thereafter approximately every 6 months from day 1 (see Section 7.2); the 
corresponding blood samples will be processed using a central laboratory.  Upon 
enrollment in FOURIER OLE study, subjects will receive evolocumab 140 mg every 
2 weeks (Q2W) or 420 mg monthly (QM) according to their preference.  Frequency and 
corresponding dose of administration can be changed at any scheduled time point where 
evolocumab is supplied to the subject, provided the appropriate supply is available.  It is 
recommended that subjects continue the same background LLT, including statin, as 
taken during FOURIER.  This study will continue for 260 weeks (approximately 5 years).  
Subjects ending administration of evolocumab should continue study assessments until 
the end of study (EOS). 
All subjects will be followed and complete procedures/assessments from enrollment 
through the date of study termination unless the subject has withdrawn consent, 
irrespective of whether the subject is continuing to receive treatment.  All deaths and 
cardiovascular events of interest (MI, stroke, coronary revascularization, hospitalization 
for unstable angina, hospitalization for heart failure, and transient ischemic attack [TIA]) 
will be reviewed by an independent external Clinical Events Committee (CEC), using 
standardized definitions. 
The overall study design is described by a study schema (Figure 1) at the end of the 
protocol synopsis section. 
The study endpoints are defined in Section 10.1.1. 
3.2 
Number of Sites 
Approximately 100 centers will participate in this study in selected European countries 
(Belgium, Denmark, Germany, France, Italy, Portugal, and Sweden).  Sites that do not 
enroll subjects within 3 to 6 months of site initiation may be closed.   
3.3 
Number of Subjects 
Participants in this clinical investigation shall be referred to as “subjects”.  Approximately 
1600 subjects will be enrolled in this study.

Study Duration for Subjects 
The study will continue for 260 weeks (approximately 5 years). 
3.5.2 
End of Study 
Primary Completion:  The primary completion date is defined as the date when the last 
subject is assessed or receives an intervention for the purposes of final collection of data 
for the primary endpoint(s), whether the study concluded as planned in the protocol or 
was terminated early.   
The primary completion date is the date when the last subject has completed the 
assessments for EOS/Safety Follow-up. 
If the study concludes prior to the primary completion date originally planned in the 
protocol (ie, early termination of the study), then the primary completion will be the date 
when the last subject is assessed or receives an intervention for evaluation in the study 
(ie, last subject last visit). 
End of Study:  The end of study date is defined as the date when the last subject is 
assessed or receives an intervention for evaluation in the study (ie, last subject last 
visit), following any additional parts in the study (eg, long-term follow-up), as applicable.

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, informed consent form (ICF), and all other 
subject information and/or recruitment material, if applicable (see Section 11.2).  Subject 
or the subject's legally acceptable representative must personally sign and date the 
IRB/IEC and Amgen approved ICF before commencement of study-specific 
activities/procedures.   
A subject is considered enrolled when the investigator decides that the subject has met 
all eligibility criteria, documents and dates this decision in the subject's medical record, 
and contacts the IVR/IWR system to enroll the subject.   
Each subject who enter into the screening period for the study (after signing the 
IRB/IEC-approved ICF) are to be assigned the same subject identification number as the 
parent study (FOURIER Study 20110118) before any study procedures are performed.  
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.

should be handled per the instructions provided in the IPIM and the instructions for use 
(IFU) for the prefilled AI/pen or PI. 
The prefilled AI/pen or PI should be inspected for investigational product quality, expiry, 
and damage before using.  Damaged, expired, or degraded product should not be used 
and any issues with the prefilled AI/pen or PI should be reported to Amgen.  Further 
details are provided in the IPIM and IFU. 
Evolocumab will be supplied directly to the site.  The method of resupply will be 
determined based on local regulations as well as available infrastructure.  The 
investigator may be required to record the box number of evolocumab (prefilled AI/pen 
or PI) on the subject’s Drug Administration electronic case report form (eCRF).  Subjects 
should return used evolocumab for reconciliation by the site. 
6.2.1.1 
Dosage, Administration, and Schedule 
Evolocumab will be administered SC Q2W or QM for approximately 260 weeks in 
accordance with the instructions in the IPIM and IFU.  The last resupply of 
evolocumab will occur 12 weeks after the week 240 visit.  The subject (or designee, 
if not a qualified healthcare professional) must have demonstrated competency at 
administration of SC injections before self-administration is permitted.  The first 
self-administered dose by the subject (or designee, if not a healthcare professional) may 
be administered at the site under the supervision of a healthcare provider at day 1.  In 
this study, evolocumab will be administered by self-administration by the subject, 
designee, or a qualified healthcare professional in a non-investigator site setting (eg, at 
home).  In exceptional circumstances, SC administration of evolocumab by a qualified 
healthcare professional in a clinic setting will also be allowed. 
When evolocumab is scheduled to be administered at the study site, the date and 
completion time of administration, the body location of the injection, whether the injection 
was fully or partially administered, and box number are to be recorded on each subject’s 
eCRF. 
When evolocumab is administered at a non-investigator site location, at a minimum, the 
dates the devices were dispensed and the used devices returned, the number of devices 
returned, box numbers, and for each device whether it was returned fully or partially 
used are to be recorded on each subject’s eCRF. 
It is suggested that the evolocumab administration is done by the subject under site staff 
supervision at each of the regular study visits to ensure continued proper use of the

injection device.  Evolocumab administration at a scheduled visit, if applicable, is to be 
performed after completion of the blood draws and vital signs. 
Details of preparing evolocumab, the injection procedures, and device disposal are 
included in the IPIM and IFU provided by Amgen before the start of the study. 
Evolocumab will be administered either at 140 mg in 1.0 mL (1 administration by prefilled 
AI/pen) Q2W or at 420 mg in 3.0 mL or 3.5 mL (3 administrations by prefilled AI/pen or 
1 administration by PI, respectively) QM.  The 3 injections for the QM administration, if 
applicable, can be administered into different injection sites.  The SC injections should 
be administered in a consecutive fashion with all injections completed within 30 minutes. 
The effects of overdose of this product are not known. 
6.2.1.2 
Dosage Adjustments, Delays, Rules for Withholding or Restarting, 
Permanent Discontinuation 
No dose adjustments of evolocumab will be allowed in this study. 
Evolocumab is administered on a Q2W or QM schedule.  Subjects will have the 
opportunity to switch between the AI/pen and PI, at any scheduled time point where 
evolocumab is supplied to the subject, provided the appropriate supply is available.  The 
first self-administration after switching the device should be done at a regularly 
scheduled visit under the supervision of the investigator or qualified study center 
staff.  Subjects who choose QM treatment will initiate treatment using the PI, provided 
the appropriate supply is available.  If the PI is not available, then the AI/pen may be 
used.  Additionally, subjects taking 420 mg evolocumab QM will have the opportunity to 
switch drug administration (3 administrations by prefilled AI/pen or 1 administration by 
PI) at any scheduled time point.  The reason for dose change of evolocumab is to be 
recorded on each subject’s eCRF(s). 
If, in the opinion of the investigator, a subject is unable to tolerate evolocumab, that 
subject will discontinue evolocumab but should continue to return for all other study 
procedures and measurements until the EOS. 
If a subject dose of evolocumab is missed or late, administration should occur as soon 
as possible if there are 7 days or more until the next scheduled dose.  If there are less 
than 7 days before the next scheduled dose, the missed dose should be omitted and the 
next dose should be administered according to the original schedule. 
The decision to rechallenge the subject after therapy changes should be discussed and 
agreed unanimously by the subject, investigator, and Amgen.  If signs or symptoms

provided in Section 6.3. 
6.2.2 
Non-Amgen Non-investigational Product 
Non-Amgen non-investigational products including background LLT (including statin), 
will also be used in this study.  These therapies will not be provided or reimbursed by 
Amgen. 
6.2.2.1 
Non-Amgen Non-investigational Product – Background 
Lipid-lowering Therapy 
6.2.2.1.1 
Dosage, Administration, and Schedule 
It is recommended that subjects continue the same background LLT, including statin, as 
taken while in FOURIER (Study 20110118).  All background LLT adjustments must be 
clearly documented and recorded on the appropriate eCRF page and in the source 
documents.  The dose, start date/time, stop date/time, frequency, and non-Amgen 
non-investigational product are to be recorded on each subject’s eCRF.  Background 
LLT will not be provided by Amgen unless required by local regulations.  
Recommendations for background LLT are provided in Appendix D. 
All other drugs that are allowed per protocol and that are prescribed for the subject must 
be commercially available and used at dosages approved by local regulatory authorities.   
Subjects should consult the investigator if they miss a dose of background statin. 
6.2.2.2 
Dosage Adjustments, Delays, Rules for Withholding or Restarting, 
Permanent Discontinuation 
The investigator should consult the local product label for information on dose 
adjustments, delays, withholding, restarting, or permanent discontinuation of background 
LLT, including statins.  The reason for dose change of non-Amgen non-investigational 
product is to be recorded on each subject’s eCRF(s). 
If a subject has elevated ad hoc laboratory values (Section 6.3) and is receiving 
background LLT, including statins, that may result in such elevations (eg, ezetimibe, 
fenofibrate, or niacin), the additional therapies should be evaluated for a potential role in 
the elevated laboratory values and considered for discontinuation.  If a subject has 
elevations in triglycerides > 500 mg/dL (5.65 mmol/L) and is concomitantly receiving a

bile acid binding resin, the bile acid binding resin should be evaluated for 
discontinuation. 
The decision to rechallenge the subject after therapy changes should be discussed and 
agreed unanimously by the subject, investigator, and Amgen.  If signs or symptoms 
recur with rechallenge of statin background therapy, the statin may be substituted by 
another statin in consultation with the Amgen medical monitor, if possible, or the statin 
therapy may be discontinued.  If signs or symptoms recur with rechallenge of other 
applicable lipid background therapy, this therapy may be discontinued. 
6.3 
Hepatotoxicity Stopping and Rechallenge Rules 
Routine hepatic laboratory assessments are not required for this study.  However, the 
guidelines (Section 6.3.1) apply for elevated liver enzymes noted during ad hoc tests.   
Subjects with abnormal hepatic laboratory values (ie, alkaline phosphatase [ALP], 
aspartate aminotransferase [AST], alanine aminotransferase [ALT], total bilirubin [TBL]) 
and/or international normalized ratio [INR] and/or signs/symptoms of hepatitis [as 
described below]) may meet the criteria for withholding or permanent discontinuation of 
Amgen investigational product or other protocol-required therapies as specified in the 
Guidance for Industry Drug-Induced Liver Injury:  Premarketing Clinical Evaluation 
(July 2009).   
6.3.1 
Criteria for Withholding and/or Permanent Discontinuation of Amgen 
Investigational Product and Other Protocol-required Therapies Due 
to Potential Hepatotoxicity 
The following stopping and/or withholding rules apply to subjects for whom another 
cause of their changes in liver biomarkers (TBL, INR and transaminases) has not been 
identified. 
Important alternative causes for elevated AST/ ALT and/or TBL values include, but are 
not limited to: 
• 
Hepatobiliary tract disease 
• 
Viral hepatitis (eg, Hepatitis A/B/C/D/E, Epstein-Barr Virus, cytomegalovirus, Herpes 
Simplex Virus, Varicella, toxoplasmosis, and Parvovirus) 
• 
Right sided heart failure, hypotension or any cause of hypoxia to the liver causing 
ischemia. 
• 
Exposure to hepatotoxic agents/drugs or hepatotoxins, including herbal and dietary 
supplements, plants and mushrooms

• 
Heritable disorders causing impaired glucuronidation (eg, Gilbert’s Syndrome, Crigler 
Najjar syndrome) and drugs that inhibit bilirubin glucuronidation (eg, indinavir, 
atazanavir) 
• 
Alpha-one antitrypsin deficiency

• 
Wilson’s disease and hemochromatosis 
• 
Nonalcoholic Fatty Liver Disease including Steatohepatitis (NASH) 
• 
Non-hepatic causes (eg, rhabdomyolysis, hemolysis) 
If investigational product(s) is/are withheld, the subject is to be followed according to 
recommendations in Appendix A for possible drug-induced liver injury (DILI). 
Rechallenge may be considered if an alternative cause for impaired liver tests (ALT, 
AST, ALP) and/or elevated TBL, is discovered and the laboratory abnormalities resolve 
to normal or baseline (Section 6.3.2).

6.3.2 
Criteria for Rechallenge of Amgen Investigational Product and Other 
Protocol-required Therapies After Potential Hepatotoxicity 
The decision to rechallenge the subject should be discussed and agreed upon 
unanimously by the subject, investigator, and Amgen. 
If signs or symptoms recur with rechallenge, then evolocumab, statins, and other 
applicable lipid background therapies should be permanently discontinued.  Subjects 
who clearly meet the criteria for permanent discontinuation (as described in Table 1) 
should never be rechallenged. 
6.4 
Concomitant Therapy 
Throughout the study, investigators may prescribe any concomitant medications or 
treatments deemed necessary to provide adequate supportive care except for those 
listed in Section 6.7.  Concomitant therapies are to be collected from informed consent 
through the end of safety follow-up period. 
Concomitant therapy and medications will be recorded on the eCRF.  The following 
groups of concomitant medications will be recorded: 
• 
cardiovascular medications 
• 
analgesics/antipyretics 
• 
anticoagulants/antiplatelets 
• 
antibiotics 
• 
antidepressants 
•

Medical Devices 
The following investigational medical devices, prefilled AI/pen or PI, will be used in this 
study and provided by Amgen (Section 6.2).  Additional details for each medical device 
is to be provided in the IPIM.   
The evolocumab AI/pen is a single use disposable, handheld mechanical "spring-based" 
device for fixed dose SC injection of 140 mg/mL evolocumab in 1.0 mL deliverable 
volume. 
The evolocumab PI is a single use, disposable, on-body electromechanical injection 
device that is copackaged with a prefilled Crystal Zenith cartridge containing 120 mg/mL 
evolocumab in a 3.5 mL deliverable volume. 
Other non-investigational medical devices may be used in the conduct of this study as 
part of standard of care.  These devices that are commercially available are not usually 
provided or reimbursed by Amgen (except, for example, if required by local regulation).  
The investigator will be responsible for obtaining supplies of these devices.   
6.6 
Product Complaints 
A product complaint is any written, electronic or oral communication that alleges 
deficiencies related to the identity, quality, durability, reliability, safety, effectiveness, or 
performance of a drug or devices after it is released for distribution to market or clinic by 
either Amgen or by distributors and partners for whom Amgen manufactures the 
material.  
This includes any drugs, devices or combination products provisioned and/or 
repackaged/modified by Amgen.  Drugs or devices includes investigational product 
(evolocumab), AI/pen, and PI.   
Any product complaints associated with an investigational product (evolocumab) or 
devices supplied by Amgen are to be reported according to the instructions provided in 
the IPIM. 
6.7 
Excluded Treatments, Medical Devices, and/or Procedures During 
Study Period 
Treatment with any investigational therapies other than study-provided evolocumab is 
not permitted during the study. 
Medications or foods that are known potent inhibitors of cytochrome P450 (CYP) 3A 
(eg, itraconazole, ketoconazole, and other antifungal azoles, macrolide antibiotics 
erythromycin, clarithromycin, and the ketolide antibiotic telithromycin, human

immunodeficiency virus [HIV] or hepatitis C virus [HCV] protease inhibitors, 
antidepressant nefazodone, and grapefruit juice in large quantities [> 1 quart daily; 
approximately 1 L]) are not recommended during the study because of their potential 
impact on metabolism of certain statins (see Appendix E). 
If a subject is enrolled and subsequently requires a treatment that is not recommended 
based on their particular statin (eg, a strong CYP3A4 inhibitor in a subject on 
atorvastatin), the treating physician should give consideration to using an equivalent 
concomitant drug (eg, a drug that does not inhibit CYP3A4 so that the subject can 
continue taking statin background therapy).  If this is not possible, it may be necessary to 
withdraw or change statin background therapy while the concomitant drug is required. 
There is no need to discontinue treatment with evolocumab should a subject require a 
nonrecommended drug (eg, a strong CYP3A4 inhibitor) since monoclonal antibody 
therapeutics are not metabolized through CYP and, thus, are unaffected by the use of 
CYP inhibitors. 
The use of antacids is not recommended within the period of 2 hours before and 2 hours 
after dosing with statins. 
6.8 
Contraceptive Requirements 
Females of Childbearing Potential 
A female is considered fertile following menarche and until becoming post-menopausal 
unless permanently sterile.  Permanent sterilization methods include hysterectomy, 
bilateral salpingectomy, and bilateral oophorectomy. 
Female in the following categories are not considered of child bearing potential: 
1. Premenopausal female with 1 of the following: 
a.  Documented hysterectomy 
b.  Documented bilateral salpingectomy 
c.  Documented bilateral oophorectomy 
Note:  Site personnel documentation from the following sources is acceptable:  
1) review of subject medical records, 2) subject medical examination, or 3) subject 
medical history interview. 
2. Premenarchal female

3. Postmenopausal female 
a.  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 HRT.  However, in the absence of 
12 months of amenorrhea, a single FSH measurement is insufficient. 
b.  Females on HRT and whose menopausal status is in doubt will be required to 
use one of the non-hormonal highly effective contraception methods if they 
wish to continue their HRT during the study.  Otherwise, they must discontinue 
HRT to allow confirmation of postmenopausal status before study enrollment. 
6.8.1 
Female Subjects 
Female subjects of childbearing potential must agree to use an acceptable method of 
effective contraception (as described in Table 2 below) during treatment and for an 
additional 15 weeks after the last dose of protocol-required therapies. 
Table 2.  Acceptable Methods of Effective Contraception for Female Subjects 
• 
combined (estrogen and progestogen) or progestogen-only hormonal methods given via 
oral, intravaginal, transdermal, injectable, or implantable route 
• 
intrauterine device (IUD) 
• 
intrauterine hormonal-releasing system (IUS) 
• 
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) 
• 
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.) 
• 
male or female condom with or without spermicide 
• 
cap, diaphragm or sponge with spermicide 
• 
double barrier method:  the male uses a condom and the female may choose either a cap, 
diaphragm, or sponge with spermicide.  A female condom is not an option due to the risk of 
tearing when both partners use a condom. 
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.

6.8.2 
Male Subjects 
Male subjects are not required to use contraception while taking evolocumab. 
6.8.3 
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 amenorrhea method. 
Female subjects of childbearing potential must receive pregnancy prevention counseling 
and be advised of the risk to fetus if they become pregnant during treatment and for 
15 weeks after the last dose of protocol-required therapies.   
Additional medications given during the study may alter the contraceptive requirements.  
These additional medications may require female subjects to use highly effective 
methods of contraception and for an increased length of time.  The investigator must 
discuss these contraceptive changes with the subject.

General Study Procedures 
Mandatory study visits will occur at day 1, week 12 and thereafter approximately every 
6 months from day 1 (each site visit has a window of ± 2 weeks).  Resupply visits will be 
scheduled quarterly (every 12 weeks).  The last resupply of evolocumab will occur 
12 weeks after the week 240 visit.  Evolocumab will be supplied directly to the site.  
Method of resupply will be determined based on local regulations as well as available 
infrastructure.  Assessments and procedures are per Schedule of Assessments  
(Table 3) and include vital signs, physical exam, body weight, concomitant therapy, 
adverse events/adverse device effects/serious adverse events/disease-related events 
assessments, fasting lipid panel, serum pregnancy testing (females of childbearing 
potential), and evolocumab administration.  If evolocumab is administered at the site, the 
administration by SC injection will be done after all other procedures have been 
completed.   
All on-study visits and dosing should be scheduled from FOURIER OLE study day 1 
(day of first administration of evolocumab in FOURIER OLE study).  When it is not 
possible to perform the study visit at the specified time point, the visit should be 
performed within the visit window in the Schedule of Assessments (Table 3).  If a study 
visit is missed or late, all attempts should be made to bring the subject in to complete 
required assessments.  If the visit occurs outside the visit window, subsequent visits 
should resume on the original visit schedule.  If possible, all study procedures for a visit 
should be completed on the same day. 
It is the responsibility of the investigator to ensure that all procedures are performed 
according to the protocol.  Written informed consent must be obtained and will be 
implemented before protocol specific procedures are carried out.  The risks and benefits 
of participating in the study will be verbally explained to each potential subject prior to 
entering into the study.  The procedures to be performed at each study visit are 
described below and the timing of the procedures is provided in the Schedule of 
Assessments (Table 3).  If performed at the site, evolocumab administration must be 
after completion of blood draw procedures, as applicable. 
The investigator should instruct the subject to report to the site (eg, telephone call) any 
adverse events, adverse device effects, serious adverse events, or disease-related 
events at any time (ie, between scheduled visits).

events at any time (ie, between scheduled visits).  In addition, subjects will be contacted 
by telephone as designated in the schedule of assessments (Table 3) for collection of 
adverse events, serious adverse events, adverse device effects, disease-related events. 
If, in the opinion of the investigator, a subject is unable to tolerate evolocumab, that 
subject will discontinue evolocumab but will continue to return for all other study 
procedures and measurements through the EOS. 
If a subject withdraws from the study early, investigators should make every effort to 
complete and report the observations as thoroughly as possible up to the date of 
withdrawal.  If possible, the week 260 procedures should be completed at the time of 
withdrawal (see Section 7.2.3). 
Vital status must be obtained for all subjects within the limits of local law.  This includes 
subjects who may have discontinued study visits with or without withdrawing consent 
and should include interrogation of public databases, if necessary.  If deceased, the date 
of death should be obtained and reported.

Description of Study Procedures 
7.2.4.1 
Medical History 
Ongoing adverse events from the end of the parent study (FOURIER), whether they 
have resolved or not at the time of signing the informed consent for the OLE (now 
classified as medical history) will be collected in the relevant medical history eCRF page.  
Medical history from prior to the date of enrollment into the parent study will not be 
collected in the OLE with the exception of heterozygous familial hypercholesterolemia 
(HeFH) diagnostic evidence.  Any medical history on local diagnoses of HeFH (ie, 
criteria outlined by the Simon Broome Register Group [Scientific Steering 
Committee, 1991], the Dutch Lipid Clinic Network [World Health Organization, 1999], 
MEDPED [Williams et al, 1993]) or confirmed by genotyping, will be collected. 
7.2.4.2 
Vital Signs 
The following measurements must be performed:  systolic/diastolic blood pressure and 
heart rate. 
Use of an automated oscillometric device for blood pressure measurement is preferred 
and recommended.  Blood pressure should be recorded using the same arm as in 
FOURIER.  The appropriate size cuff should be used.  Blood pressure and heart rate 
measurements will be determined after the subject has been seated for at least 
5 minutes.  The subject’s pulse should be measured for 30 seconds and the number 
multiplied by 2 to obtain heart rate. 
Record all measurements on the vital signs eCRF. 
7.2.4.3 
Review of Safety Events 
All adverse events, serious adverse events, adverse device effects, and disease-related 
events must be recorded on the subject’s eCRF that occur after signing the ICF through 
the EOS/Safety Follow-Up visit for this study, or 30 days (+ 3 days) after the last 
administration of evolocumab, whichever is later.  All reported adverse events are 
followed until resolution or stabilization.

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 possibilities for continuation of the Schedule of Assessments 
(Table 3) and collection of data, including endpoints and adverse events and must 
document this decision in the subject’s medical records.  The investigator must discuss 
the different options of follow up (eg, in person, by telephone/mail, through 
family/friends, in correspondence/communication with other treating physicians, from 
review of the medical records or public records as permitted by applicable law).  Such 
public record searches may be conducted by the site or vendors approved by the site.  
Subjects who have discontinued investigational product, device, and/or protocol required 
therapies as well as study assessments or procedures should not be automatically

removed from the study.  Whenever safe and feasible, it is imperative that subjects 
remain on-study to ensure safety surveillance and/or collection of outcome data.   
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, publicly 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 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. 
8.3 
Reasons for Removal From Treatment or Study 
8.3.1 
Reasons for Removal From Treatment 
Reasons for removal from protocol-required investigational product(s) or procedural 
assessments include any of the following: 
• 
subject request 
• 
safety concern (eg, due to an adverse event, ineligibility determined, protocol 
deviation, non-compliance, requirement for alternative therapy, protocol-specified 
criteria [see Section 6.2.1.2], pregnancy) 
• 
death 
• 
lost to follow-up 
• 
decision by Sponsor (other than subject request, safety concern, lost to follow-up) 
8.3.2 
Reasons for Removal From Study 
Reasons for removal of a subject from the study are: 
• 
decision by sponsor 
• 
withdrawal of consent from study 
• 
death 
• 
lost to follow-up

8.4 
Lost to Follow-up 
A subject will be considered lost to follow-up at the end of the study if he or she 
repeatedly fails to return for scheduled visits and is unable to be contacted by the study 
site. 
The site must attempt to contact the subject at each scheduled visit and reschedule the 
missed visit as soon as possible and counsel the subject on the importance of 
maintaining the assigned visit schedule and ascertain whether or not the subject wishes 
to and/or is able to continue in the study.  These contact attempts are to be documented 
in the subject’s medical record. 
For subjects who are lost to follow-up, the investigator (or vendors approved by the site) 
can search publicly available records as permitted by applicable law to ascertain survival 
status.  This ensures that the data set(s) produced as an outcome of the study is/are as 
comprehensive as possible. 
9. 
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 have 
hyperlipidemia and clinically evident atherosclerotic CVD.  Therefore, disease-related 
events include the following:  manifestations and complications of atherosclerotic 
vascular disease such as coronary artery disease, angina, MI, ischemic stroke, TIA, 
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 due to the disease under study is to be recorded on the Event eCRF. 
Approved 
 
 


Product:  Evolocumab 
Protocol Number:  20160250 
Date:  19 February 2020 
Page 42 of 70 
CONFIDENTIAL 
 
 
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 (evolocumab)/study 
treatment/protocol-required therapies and disease worsening, this must be reported 
as an adverse event or serious adverse event. 
Disease-related events will be collected through OLE duration including the safety 
follow-up visit, and will be recorded using the Event eCRF per Section 9.2.1.  
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 
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.   
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. 
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 after signing the ICF through the 
EOS/Safety Follow-Up visit for this study, or 30 days (+ 3 days) after the last 
administration of evolocumab, whichever is later, are recorded on the Event eCRF as a 
disease-related event.   
All serious disease-related events will be recorded and reported to the sponsor or 
designee within 24 hours.  The investigator will submit any updated serious 
disease-related event data to the sponsor within 24 hours of it being available.

Disease-related events assessed by the investigator to be more severe than expected 
and/or related to the investigational medicinal product (evolocumab)/study 
treatment/protocol-required therapies, and determined to be serious, must be recorded 
on the Event eCRF as serious adverse events.   
Additionally, the investigator is required to report a fatal disease-related event on the 
Event eCRF as a disease-related event.   
9.2.2 
Adverse Events 
9.2.2.1 
Reporting Procedures for Adverse Events That do not Meet Serious 
Criteria 
The investigator is responsible for ensuring that all adverse events and adverse device 
effects observed by the investigator or reported by the subject that occur after signing 
the ICF through the EOS/Safety Follow-Up visit for this OLE study, or 30 days (+ 3 days) 
after the last administration of evolocumab, whichever is later, are reported using the 
Event eCRF. 
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 
• 
assessment of relatedness to investigational product (evolocumab and/or the 
medical devices [prefilled AI/pen or PI]), any study-mandated activity or procedure, 
or other protocol-required/study-mandated therapies) 
• 
action taken 
If the severity of an adverse event changes from the date of onset to the date of 
resolution, record as a single event with the worst severity on the Event eCRF. 
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 (evolocumab) and/or other protocol-required therapies.  
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 the investigational 
medicinal product and/or other protocol-required therapies? 
The investigator must assess whether the adverse event is possibly related to the 
prefilled AI/Pen or PI investigational devices used to administer investigational medicinal

product (evolocumab).  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, use of medical devices and/or procedure including any screening 
procedures).  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 investigational product, protocol-required therapies, use of medical 
devices), and/or procedure?  
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 the ICF through the 
EOS/Safety Follow-Up visit for this study, or 30 days (+ 3 days) after the last 
administration of evolocumab, whichever is later are recorded in the subject’s medical 
record and are submitted to Amgen.  All serious adverse events must be submitted to 
Amgen within 24 hours following the investigator’s knowledge of the event via the Event 
eCRF.   
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 (eSAE) Contingency Report Form within 24 hours of the 
investigator’s knowledge of the event.  See Appendix B for a sample of the Serious 
Adverse Event Worksheet/eSAE Contingency Report Form.  For EDC studies where the

first notification of a Serious Adverse Event is reported to Amgen via the eSAE 
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 (evolocumab) and/or other protocol-required therapies.  
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 the investigational 
medicinal product and/or other protocol-required therapies? 
The investigator must assess whether the serious adverse event is possibly related to 
the prefilled AI/Pen or PI investigational devices used to administer investigational 
medicinal product (evolocumab).  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 serious adverse event is possibly related to 
any study-mandated activity (eg, administration of investigational product, 
protocol-required therapies, use of medical devices and/or procedure including any 
screening procedures).  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 investigational product, protocol-required therapies, 
use of medical devices), 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 eCRF. 
If a subject is permanently withdrawn from protocol-required therapies because of a 
serious adverse event, this information must be submitted to Amgen. 
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 (GCP).  
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 EOS.  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. 
9.3 
Pregnancy and Lactation Reporting 
If a female subject becomes pregnant 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 
report pregnancies that occur for an additional 15 weeks after the last dose of 
evolocumab.  
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 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.

If a female breastfeeds while taking protocol-required therapies report the lactation case 
to Amgen as specified below.  
Any lactation case should be reported to Amgen Global Patient Safety within 24 hours of 
the investigator’s knowledge of event.  Report a lactation case on the Lactation 
Notification Worksheet (Appendix C).  Amgen Global Patient Safety will follow-up with 
the investigator regarding additional information that may be requested. 
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. 
Amgen is sponsoring a prospective, observational study of pregnant women who have 
been exposed to Repatha® (evolocumab) at any point during pregnancy and/or 
breastfeeding.  The registry is conducted in Europe, South Africa, and Australia.  
Participants are not asked to make any changes to their healthcare routine.  While 
subjects who are pregnant are not eligible for the 20160250 study, if a site 
investigator/health care practitioner has a subject who becomes pregnant while receiving 
evolocumab, they will be advised to refer the subject to Amgen’s evolocumab pregnancy 
registry according to the place of residency.  More information on the pregnancy registry 
study in Europe, South Africa, and Australia is available in the respective study protocol

Interim Analyses 
There will be interim analyses to support safety data reporting and assessments of other 
listed endpoints.  The study is not anticipated to stop early unless a major unexpected 
safety signal is detected.  
10.3.2 
Primary Analysis 
Primary analysis activities are commenced based on achieving the EOS milestone 
described in Section 3.5.2. 
10.4 
Planned Methods of Analysis 
10.4.1 
General Considerations 
Statistical analyses in this open label study are descriptive in nature.  No statistical 
inference or missing value imputation is planned.  No formal hypothesis will be tested in 
this study.  Subject disposition, demographics, and baseline characteristics 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.  Unless specified 
otherwise, the baseline value is defined as the subject’s baseline value from the parent 
study (FOURIER) and all analyses (primary, secondary, exploratory, and safety) will be 
performed on the OLE safety analysis set.  For all endpoints, results will be summarized

by the randomized treatment group from the FOURIER study and overall, unless 
specified otherwise. 
The primary analysis of all primary, secondary, and exploratory endpoints will use data 
from the OLE study only.  Additional analyses combining the data from the OLE study 
and FOURIER study will be performed as applicable. 
All deaths and cardiovascular events of interest (MI, stroke, coronary revascularization, 
hospitalization for unstable angina, hospitalization for heart failure, and TIA) will be 
reviewed by an independent external CEC, using standardized definitions.  The CEC is 
external to Amgen and primarily comprises both academic clinical physicians (to include 
cardiologists) and medical reviewers trained on the clinical trial protocol, the CEC 
charter, and CEC processes.  The chairman of the CEC is responsible for overseeing 
the operations in conformance with the CEC charter and for supervising the flow of data 
between the sponsor/data management and the CEC. Committee members are qualified 
in the appropriate subspecialty and free of conflict of interest.  The CEC reviews events 
according to pre-specified criteria defined in the CEC charter.  The CEC will be blinded 
to the original randomized treatment group from the FOURIER study. 
10.4.2 
Primary Endpoint 
The current Medical Dictionary for Regulatory Activities (MedDRA) version at the time of 
the data lock will be used to code all adverse events and disease related events to a 
system organ class and preferred term.  Exposure adjusted subject incidence rates of all 
treatment emergent adverse events, serious adverse events, fatal adverse events, 
adverse events leading to withdrawal from investigational product, device-related 
adverse events, and disease related events will be tabulated for overall OLE study 
period.  These events will also be presented by yearly subject exposure time intervals .   
All adverse event summaries for the primary analysis of the primary endpoint will 
include all treatment-emergent events reported on the Event eCRF, including CEC 
reviewed events and disease related events.  All CEC reviewed events will be 
reported. 
Adverse event data from the OLE study will also be combined with FOURIER study data 
as an additional analysis and positively reviewed events will not be included in the 
adverse event analysis to remain consistent with FOURIER adverse event reporting.

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 Manager to the investigator.  The written ICF 
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 (evolocumab) is 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.   
The acquisition of informed consent and the subject’s agreement or refusal of his/her 
notification of the primary care physician is to be documented in the subject’s medical

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, eCRFs and other 
pertinent data) provided that subject confidentiality is respected. 
The Clinical Monitor is responsible for verifying the eCRFs 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 eCRFs. 
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 eCRFs, 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 eCRFs must be maintained and 
readily available. 
• 
Updates to eCRFs 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 EDC study or 
the investigator applies an electronic signature in the EDC system if the study is set 
up to accept an electronic signature.  This signature indicates that investigator 
inspected or reviewed the data on the eCRF, the data queries, and agrees with the 
content.

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 3), the investigator can search publicly 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 
The eCRFs 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 (ICMJE, 2013), 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.

Drug-induced Liver Injury Reporting & Additional Assessments  
Reporting 
To facilitate appropriate monitoring for signals of drug-induced liver injury (DILI), cases 
of concurrent aspartate aminotransferase (AST) or alanine aminotransferase (ALT) and 
total bilirubin (TBL) and/or international normalized ratio (INR) elevation according to the 
criteria specified in Section 6.3 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 case report form (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 > 3x upper limit of normal (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, alkaline phosphatase (ALP), bilirubin (total and direct), and INR 
within 24 hours  
• 
In cases of TBL > 2x ULN or INR > 1.5, retesting of liver tests, bilirubin (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 G, 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 
− 
creatine phosphokinase (CPK), haptoglobin, lactate dehydrogenase (LDH), and 
peripheral blood smear 
− 
appropriate liver imaging if clinically indicated 
• 
appropriate blood sampling for pharmacokinetic analysis if this has not already been 
collected  
• 
hepatology consult (liver biopsy may be considered in consultation with an 
hepatologist) 
• 
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 corresponding electronic case 
report forms (eCRFs).

Appendix D.  Recommended Lipid-lowering Background Therapy 
It is recommended that subjects continue the same background lipid-lowering therapy 
(LLT), including statin, as taken during FOURIER.  Background LLT should be optimized 
for the individual subject consistent with local professional society guidelines.  All 
subjects should receive at least an effective statin dose, ie, at least atorvastatin 20 mg 
daily or equivalent.  Where locally approved, highly effective statin therapy, defined as at 
least atorvastatin 40 mg daily or equivalent, is recommended. 
No other lipid therapy is required for the FOURIER OLE study.  Ezetimibe and other 
commercially available lipid therapy at dosages approved by local regulatory authorities 
may be added to any of these regimens except excluded medication as per Section 6.7.  
These therapies, including statins, are not provided or reimbursed by Amgen (except if 
required by local regulation).  Background LLT received at enrollment should remain 
unchanged throughout the entire duration of the study.

NCT number:  NCT03080935 
 
Amendment Date: 
19 February 2020 
 
Rationale: 
This protocol is being amended to: 
• 
Update safety language: 
− 
Safety Section updated to reflect that all serious drug-related events must be 
recorded and reported to the sponsor or designee within 24 hours 
− 
Included “coronary revascularization” throughout the protocol to identify the 
specific vascular territory of interest, which is the coronary circulation. 
− 
The identified Events of Interest (EOIs) were removed from the protocol and are 
no longer pre-specified. 
• 
Update the Schedule of Assessments: 
− 
Added week 260 (replacing End of Investigational Product Administration [EoIP]) 
back into the schedule of assessments to realign with the 20130295 sister study 
and to clarify that the week 260 visit still applies. 
− 
Coronary revascularization procedure and death information added throughout to 
support the independent safety review of cardiovascular events of interest and 
deaths by the Clinical Events Committee. 
• 
Clarify dosing details: 
− 
details regarding the switch frequency between auto-injector/pen (AI/pen) and 
personal injected (PI) were added, and  
− 
the last resupply of evolocumab will occur 12 weeks after the week 240 visit. 
• 
Update the exploratory objectives in Section 1.3 to be consistent with exploratory 
endpoints in Section 10.1.1.3 
• 
Remove language in the definition of Primary Completion to align with current 
protocol template.

Long term Safety of Evolocumab Therapy in Subjects With Clinically Evident 
Cardiovascular Disease in Selected European Countries 
 
Amgen Protocol Number (evolocumab) 20160250 
 
Amendment Date: 
14 December 2018 
Rationale: 
The following changes are being made to the study for the reasons indicated: 
• 
Financial disclosure statement text removed as this is not applicable to this study 
(only European sites will be participating) 
• 
An independent external Clinical Events Committee was established and will 
review deaths and cardiovascular events of interest; cardiovascular events of 
interest to be reviewed were defined 
• 
The term “targeted” concomitant therapy was removed throughout; all 
concomitant therapy will be assessed. 
• 
Clarification of statistical considerations:  primary analysis of all endpoints in the 
OLE study will only use OLE study data and how CEC events will be analyzed. 
• 
Exposure time intervals were modified 
• 
Clarifications of text or update with current template and Amgen standards: 
o Clarification of text to indicate that the lipid profiles are conducted at 
scheduled visits and not on a yearly basis 
o Self-evident correction text was removed as it is no longer an Amgen 
standard 
o Week 260 was removed as part of end of study definition for clarity 
o Concomitant therapy for disease under study, antibiotics, and then all 
other therapies:  information collected was clarified  
o Male contraception language removed as not applicable. 
o Clarification of how data will be collected and defined when a subject 
transitions from parent to OLE study, including medical history and what 
data will be transferred to OLE was provided. 
o Definition of subject withdrawal updated throughout and aligned with 
current template. 
o Redundant text for subject withdrawal and concomitant therapy removed. 
o Resupply period was clarified  
o Lot number was changed to box number for accuracy

events of interest :revascularization 
with coronary revascularization 
throughout this SAP 
Rationale: To identify the specific 
vascular territory of interest, which is 
the coronary circulation 
4. Change the definition of age in 
section 5.2 
Rationale: To clarify age at enrollment 
is the subject’s age in years as 
recorded on Demographics eCRF of 
the parent study 
5. Remove adverse event events of 
interest (EOIs) throughout this SAP 
Rationale: Events of interest (EOIs) 
are no longer pre-specified in the 
protocol 
6. Update the wording of the primary 
endpoint in Table 9-1 
Rationale: This change is to make it 
clear that all events listed are 
treatment emergent 
7. Update the language in Section 9.5.1 
Analyses of Primary Endpoint 
Rationale: To clarify that all adverse 
event summaries will include not only 
Clinical Events Committee (CEC) 
reviewed events but also disease 
related events; to clarify that subject 
incidence and exposure-adjusted 
subject incidence rate will be 
tabulated by system organ class, high 
level term and preferred term which is 
similar to how they were summarized 
for the parent study;  to clarify that 
disease related events will be coded 
with Medical Dictionary for Regulatory 
Activities (MedDRA) 
8. Remove the fifth and the seventh 
paragraphs in section 9.5.1

objective in section 10 
Rationale: The exploratory objective 
not included in Protocol Amendment 1 
are now included in Protocol 
Amendment 2 
13. Remove End of Investigational 
Product Administration (EOIP) in 
Appendix. A 
Rationale: To realign with the 
20130295 sister study and to clarify 
that week 260 visit applies 
14. Add one analysis in section 9.7 
Rationale: The team agree on adding 
a listing for events which occurred in 
the time between the subject’s EOS

Summary of Changes,  
including rationale for changes 
Amendment 2 (v3.0) 
24March2022 
Changes: 
1. Change in one of the author of Study 
Statistician from 
 to 
 
2. Update statistical analysis plan (SAP) 
version and date throughout this SAP 
Rationale: Statistical analysis plan 
was amended 
3. Removed long-term safety analysis 
set (including parent [FOURIER] 
subjects who did not rollover into this 
OLE study) and related analysis from 
SAP and clarified the rationale in 
section 10. 
Rationale: The pre-specified planned  
analyses in the SAP focus on the long 
term safety data in the subjects who 
enrolled into this OLE study (i.e., OLE 
safety analysis set) rather than the long-
term safety analysis set which also 
includes parent study subjects who did 
not rollover into this OLE study. We will 
include parent studydata and OLE data 
from those that enrolled in the OLE for 
the analysis. More details will be 
provided in SAP section 9. 
4. Add the explanations for “ABI” and 
“PAD” in the list of abbreviations 
Rationale: To explain the abbreviation 
of a new definition added in section 
5.2 
5. Added explanation for “K-M” in the list 
of abbreviations as included for 
efficacy tables. 
6. Added a new subgroup analysis in 
the list per request from Clinical team 
to analyze the long term exposure 
effect in subjects with evolocumab. 
7. Update the definition of planned 
covariates in section 4.1 
Rationale: Since this study is for 
estimation and summarizes 
descriptive statistics.  Covariate 
analysis involves modelling; 
therefore, covariate analysis is not 
applicable for this study. 
8. Update section 5 to include definition 
of censoring date and time to event 
Rationale: We need those to be able to 
compare the results of OLE vs parent 
study. 
9. Provided more details on the 
definition of last dose date in section 
5.1 and apparently updated language 


Product:  Evolocumab 
Protocol Number:  20160250 
 
Date:  24 March 2022 
Page 5 of 38

in definition for Enrollment date and 
Study day 1. 
10. Added Categories of Time to first-
event Endpoints with definitions and 
derivations in section 5.1 
11.  Rationale – To incorporate the last 
known survival status information 
when censoring for mortality 
endpoints especially for those lost 
to follow up patients or patients 
that withdrew consent. 
12. Updated derivation for patient years 
of follow up for TEAE. 
             Rationale – To count parent study 
and OLE period as two distinct periods which 
are added together, rather than 1 period from 
parent study’s first dose to end of OLE 
 
13. Update IP and Study Exposure 
Derivation for the combined parent 
and OLE study period. 
Rationale – To only sum of the two 
separate study exposure from the 
parent study and OLE studies (i.e., 
excluding the gap time between end 
of parent study and start of OLE) 
instead of the continuous study 
exposure from start of parent study till 
end of OLE (i.e., including the gap 
time between end of parent study and 
start of OLE. 
14. Update section 8.3.2 to include 
imputation methods for handling 
partial dates of the CEC reviewed 
events and death events. 
     Rationale: To be consistent with            
Fourier reporting. 
15. Update the wording of the primary 
endpoint in Table 9-1 
Rationale: This change is to clarify 
that all events listed are treatment 
emergent 
16. Updated section 9.3 to include 
COVID-19 related protocol deviations 
and important protocol deviations 
Rationale: Per GDE-409220, the 
COVID-19 related PD and IPD will also 
be summarized and listed as per Amgen 
standard 
17. Update the language in section 9.5.1 
Analyses of Primary Endpoint 
Rationale: To clarify that all adverse 
event summaries will include not only 
Clinical Events Committee (CEC) 
reviewed events but also disease 
related events; to clarify that disease 
related events will be coded with

Protocol Number:  20160250 
 
Date:  24 March 2022 
Page 6 of 38

Medical Dictionary for Regulatory 
Activities (MedDRA) 
18. Updated section 9.5.2 and section 
9.5.3 
Rationale – To specify that those 
would be analyzed. 
19. Update the LDL-C subgroup to LDL-
C40 mg/dl in section 9.6.1 
     Rationale: LDL-C  40 mg/dl is used 
to be consistent with other low LDL-C 
achievement analysis 
20. Updated section 9.5.3 for sensitivity 
analysis 
Rationale – To perform analysis for 
cardiovascular events that occurred 
during the gap (i.e.between subjects 
EOS date in parent study and OLE 
study enrolment date). 
21. Specified the analysis set in section 
9.6.1, 9.6.2, 9.6.3, 9.6.4 and 9.6.5. 
22. Updated the analysis window for 
week 260 
Rationale: to make sure the lipid 
assessments are properly included 
for the analysis 
23. Updated term from “FOURIER” to 
“parent” study. 
24. Added Appendix D. 
Rationale – To understand the 
ACC/AHA guidelines for lipid 
modifying background therapy.

2.2 
Hypotheses and/or Estimations 
The primary clinical hypothesis is that long-term exposure of evolocumab will be safe 
and well tolerated in subjects with clinically evident atherosclerotic cardiovascular 
disease (CVD). 
3. 
Study Overview 
3.1 
Study Design 
This is a multicenter, open-label extension (OLE) study designed to assess the extended 
long-term safety of evolocumab in subjects who have completed the FOURIER trial 
(Study 20110118). FOURIER is a randomized placebo-controlled study of evolocumab, 
in patients with clinically evident atherosclerotic CVD on stable effective statin therapy. 
Subjects at sites participating in FOURIER OLE (Study 20160250) who are eligible and 
have signed the FOURIER OLE informed consent will be enrolled after completion of 
FOURIER.  
The FOURIER OLE study requires laboratory assessments at day 1, week 12, and 
thereafter approximately every 6 months from day 1; the corresponding blood samples 
will be processed using a central laboratory.  
Upon enrollment in FOURIER OLE study, subjects will receive evolocumab 140 mg 
every 2 weeks (Q2W) or 420 mg monthly (QM) according to their preference. Frequency 
and corresponding dose of administration can be changed at any scheduled time point 
where evolocumab is supplied to the subject, provided the appropriate supply is 
available. It is recommended that subjects continue the same background lipid-lowering 
therapy (LLT), including statin, as taken during FOURIER.  
This study will continue for 260 weeks (approximately 5 years). Subjects ending 
administration of evolocumab should continue study assessments until the end of study. 
All subjects will be followed and complete procedures/assessments from enrollment 
through the date of study termination unless the subject has withdrawn consent, 
irrespective of whether the subject is continuing to receive treatment. All deaths and 
cardiovascular events of interest will be reviewed by an independent external Clinical 
Events Committee (CEC), using standardized definitions. 
3.2 
Sample Size 
It is estimated approximately 1600 subjects who completed the FOURIER trial will be 
enrolled. Based on sample size of 1600 subjects, Table 3-1 lists the width of 
95% confidence interval (CI) for a range of various underlying adverse event rates.

or on subject last confirmed survival status date in the parent study (i.e., primary 
analysis in the parent study; please see the definition in the parent study SAP 
version 3.1 dated Aug 09, 2016) are included in addition to the events reviewed 
as positive in the OLE study (defined as below). 
 
For the time-to-first-event analysis based on the OLE data only, mortality 
events reviewed as positive and occurred prior to or on later of (the EOS 
date or last known survival status date from eCRF page(s) in this OLE 
study) and non-mortality events reviewed as positive and occurred prior to 
or on the EOS date are included.  For those subjects who already 
experience such event in the parent study, their time to event and censor 
flag are same as those in the parent study.

Study Exposure Period in Months (For the combined parent and OLE periods) 
For each subject, study exposure in combined periods is the sum of the study 
exposure in the parent study (defined above) plus the study exposure in the OLE 
period (defined above). 
Reflexive Approach for LDL-C and VLDL-C 
For all analyses related to LDL-C and VLDL-C, unless specified otherwise, an LDL-C 
reflexive approach will be used. When calculated LDL-C is less than 40 mg/dL or 
triglycerides are  400 mg/dL, the ultracentrifugation (UC) LDL-C value and UC VLDL-C 
value from the same blood sample will be used instead, if available. 
Two Consecutive LDL-C Values  cutoff (25 mg/dL and 40 mg/dl)The algorithm for 
defining the 2 consecutive LDL-C values  25 mg/dL / 40 mg/dL separated by at least 
21 days within OLE study period is summarized below: 
1) For each blood sample draw date that has at least one LDL-C value within OLE 
study period, identify the lowest LDL-C value 
a. If UC values exist regardless of the presence of calculated LDL-C values, 
the lowest UC LDL-C value will be used 
b. If only calculated LDL-C values exist, the lowest calculated LDL-C value 
will be used 
2) If a subject has 2 consecutive (separated by at least 21 days) LDL-C values that 
are  25 mg/dL / 40 mg/dL within OLE study period, then the subject will be 
considered as a subject with two consecutive LDL-C values  25 mg/dL / 40 
mg/dL within OLE study period. 
Two consecutive LDL-C in the parent study has been defined and derived in the same 
way as above.

Planned Analyses 
7.1 
Interim Analysis and Early Stopping Guidelines 
Interim analysis will be performed to support safety data reporting and assessments of 
other listed endpoints. 
7.2 
Primary Analysis 
Primary analysis activities are commenced based on achieving the EOS milestone 
described in Protocol Section 3.5.2. 
8. 
Data Screening and Acceptance 
8.1 
General Principles 
The objective of the data screening is to assess the quantity, quality, and statistical 
characteristics of the data relative to the requirements of the planned analyses. 
8.2 
Data Handling and Electronic Transfer of Data 
The Amgen Global Study Operations-Data Management (GSO-DM) department will 
provide all data to be used in the planned analyses.  This study will use the RAVE 
database. 
All data collected in the eCRF will be extracted from RAVE. Protocol deviations will be 
transferred from eClinical. Details on data transfer will be provided in the Data Transfer 
Plan. 
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 data cutoff date. 
The frequency and pattern of missing data for selected endpoints will be assessed 
through descriptive summaries of the measurements over time. 
There will be no imputation for missing data other than date imputation described in the 
next section. 
8.3.2              Handling of Missing Data 
Missing and partially missing dates will be queried. Partial/missing EOS dates will 
be imputed as the maximum of (last dose date of IP, vital signs assessments, lab 
assessments, AE start dates, concomitant medication start dates and imputed 
EOS date if partially missing). Partial/missing onset dates (reviewed by CEC) of

Protocol Number:  20160250 
 
Date:  24 March 2022 
Page 24 of 38 
CONFIDENTIAL 
 
 
time-to- first-event endpoints will be imputed using the following algorithm, with 
the reference date being the enrollment date.  
• Impute the missing year as the year of the reference date  
• Impute the missing month as January  
• Impute the missing day as 1st  
Partial/missing start dates of adverse events and disease-related adverse events 
will be imputed using the following algorithm, with the reference date being the 
first dose date. 
• Impute the missing year as the year of the reference date  
• Impute the missing month as January  
• Impute the missing day as 1st  
If any of the resulting dates are prior to the reference date, the imputed date will 
be reset to the reference date. Please note for completely missing start dates of 
adverse-events and disease-related adverse where ‘Did event start before first 
dose of investigational product?’ on eCRF is recorded as ‘Yes’ will not be 
imputed. In addition, any imputed death dates will be the maximum of (the all 
adverse event start dates [use imputed event dates if missing], subject EOS dates 
[use imputed EOS dates if missing], and subject last confirmed survival status 
date recorded on the survival status eCRF page). For CEC death events and AE 
death event start dates, missing or partial missing dates will use the imputed 
death dates. 
Adverse events with a valid answer to the question ‘Did event start before first dose of 
investigational product?’ on eCRF can be well defined based on the answer regardless 
of dates being completely or partially missing. Adverse events that cannot be determined 
as prior to IP or not either by the question above or by the onset date will be counted as 
treatment-emergent adverse events. 
Concomitant medication with completely or partially missing start dates will be queried. 
After the query is resolved and the date is still incomplete with year only or year and 
month only, the start date will be imputed as described in Table 8-1 below.

There are two cases for start date is missing: 
 
End date is after first dose date or missing (i.e. medication is ongoing), the 
medication will be considered as being taken at OLE study baseline and post 
baseline. 
 
End date is prior to first dose date, the medication will not be considered as 
being taken at OLE study baseline or post baseline. 
Partial/missing start dates of cardiovascular medical history events which 
occurred during the gap between subjects' EOS date in the parent study and OLE 
study enrolment date will be imputed as follows for the sensitivity analysis: 
 
If day is missing, impute to 1st of the month. If the partial start date is the 
same month as EOS date in parent study, impute to EOS date in parent study 
+1 
 
If day and month are missing, impute to 1st Jan of that year. If the partial start 
date is the same year as parent study EOS date, impute to EOS date in parent 
study +1 
 
If start date is completely unknown, no imputation and event will not be 
considered in the gap 
 
8.4 
Detection of Bias 
Important protocol deviations likely to impact the analysis and interpretation of the 
endpoints will be tabulated in the Clinical Study Report (CSR). 
If any sensitivity analyses are required to evaluate potential biases in the study’s 
conclusions, the sources of the potential biases and results of the sensitivity analyses 
will be documented in the CSR.  
8.5 
Outliers 
Various methods, including univariate summaries, histograms, scatter plots, box plots, 
and line graphs, will be used to identify outliers in key variables. Extreme data points will

be identified during the review of the data prior to database snapshot. Such data points 
will be reviewed with clinical data management to ensure accuracy. Unless specified 
otherwise, all analyses will include outliers in the data. Sensitivity analyses may be 
undertaken if extreme outliers for a variable are observed. 
8.6 
Distributional Characteristics 
There are no distributional requirements for the planned analyses. Therefore, no 
assessment will be made. 
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.   
Tables, figures, and listings will be produced with validated standard macro programs 
where standard macros can produce the specified outputs.   
The production environment for statistical analyses consists of Amgen-supported 
versions of statistical analysis software; for example, the SAS System version 9.4 or 
later.

General Considerations 
Statistical analyses in this open-label study are descriptive in nature. No formal 
hypothesis will be tested in this study. No statistical inference is planned.  
Subject disposition, demographics, and baseline characteristics and exposure to IP will 
be summarized.   
Summary statistics for continuous variables will include the number of subjects (n), 
mean, standard deviation (SD) or standard error (SE), median, the first (Q1) and third 
(Q3) quartiles, minimum, and maximum. For categorical variables, the frequency and 
percentage will be given. The baseline value is defined as the subject’s baseline value 
from the parent study as defined in Section 5.2, unless specified otherwise. All analyses 
will be performed on the OLE safety analysis set. 
Interim and final analyses will be based on data collected from this study combined with 
the data from the FOURIER study as applicable. For all endpoints, results will be 
summarized by the randomized treatment group from the parent study and overall, 
unless specified otherwise.

All deaths and cardiovascular events of interest (MI, stroke, coronary revascularization, 
hospitalization for unstable angina, hospitalization for heart failure, and TIA) will be 
reviewed by an independent external CEC, using standardized definitions. The CEC is 
external to Amgen and primarily comprises both academic clinical physicians (to include 
cardiologists) and medical reviewers trained on the clinical trial protocol, the CEC 
charter, and CEC processes. The chairman of the CEC is responsible for overseeing the 
operations in conformance with the CEC charter and for supervising the flow of data 
between the sponsor/data management and the CEC. Committee members are qualified 
in the appropriate subspecialty and free of conflict of interest. The CEC reviews events 
according to pre-specified criteria defined in the CEC charter.  The CEC will be blinded 
to the original randomized treatment group from the parent study. 
There will be no imputation for missing data other than date imputation described in 
Section 8.3.2 
9.2 
Subject Accountability 
The number and percent of subjects who were enrolled into the OLE study, received IP, 
completed IP, discontinued IP and reasons for discontinuing during the OLE study, 
completed the OLE study, and discontinued the OLE study and reasons for 
discontinuing will be summarized by the randomized treatment group in parent study and 
overall. 
OLE enrollment by region, country and investigator and, key study dates for the first 
subject enrolled, last subject enrolled and last subject’s end of study will be presented. 
9.3 
Important Protocol Deviations 
Important Protocol Deviations (IPDs) categories are defined by the study team before 
the first subject’s 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 reporting Protocol Deviations and Important Protocol 
Deviations due to COVID-19 impact will be summarized in a table. A Protocol 
Deviation listing of subjects impacted due to COVID-19 impact will also be 
provided.

Demographic and Baseline Characteristics 
All baseline tables will be summarized by the randomized treatment groups in parent 
study. Baseline tables will summarize the following: baseline characteristics, 
demographics, cardiovascular medical history, laboratory parameters, physical 
measurements and lipid regulating medication.

9.5.1 
Analyses of Primary Endpoint 
The current Medical Dictionary for Regulatory Activities version at the time of data lock 
will be used to code all adverse events (AEs) and disease related events to a system 
organ class and a preferred term. 
Treatment-emergent adverse events are events with an onset after the administration of 
the first dose of investigational product as defined in Section 5.3. 
The subject incidence and exposure-adjusted subject incidence rate of all 
treatment-emergent adverse events, serious adverse events, fatal adverse events, 
adverse events leading to withdrawal of evolocumab, device-related adverse events, 
and disease-related events will be tabulated by system organ class (SOC), high level 
term (HLT), and preferred term (PT) in alphabetical order for the overall OLE study 
period using the OLE safety analysis set. These events will also be presented by yearly 
subject exposure time intervals. All adverse event summaries for the primary analysis of 
the primary endpoint will include all treatment-emergent events reported on the Event 
eCRF, including CEC reviewed events and disease related events. 
The analyses described above (subject incidence, exposure-adjusted subject incidence 
rate) will also be performed combining data from the OLE study and the parent study

using the OLE safety analysis set and also be analyzed separately for the 
subgroup of subjects who were randomized to and received evolocumab group in 
the parent study with ≥ 7 years of the combined exposure for evolocumab across 
the parent and OLE study. Events from parent study classified as Target IP TEAEs will 
be included (adverse events occurring from the first dose of IP date to 30 days after the 
last dose of IP date or EOS, whichever occurs first). Disease-related events from the 
OLE study will be reclassified as adverse events and positively reviewed events from the 
OLE study will not be included to remain consistent with parent study adverse event 
reporting. This analysis will be presented by the randomized treatment in the parent 
study. 
Subject incidence of treatment emergent and serious adverse events occurring in at 
least 1% of the subjects by preferred term will be provided in descending order of 
frequency for the overall OLE study period only and combined parent and OLE study 
periods.   
 
9.5.2 
Analyses of Secondary Endpoints 
Summary statistics of the secondary endpoints (percent change of LDL-C from baseline 
and achieving an LDL-C level < 40 mg/dL) will be analyzed based on the OLE Safety 
Analysis Set at each scheduled visit for the overall parent and OLE study periods. 
9.5.3 
Analyses of Exploratory Endpoints 
The change and percent change from baseline in lipid parameters at each scheduled 
visit will be summarized based on the OLE Safety Analysis Set for the overall parent 
and OLE study periods. For continuous exploratory endpoints, summary statistics 
(number of subjects, mean, median, standard deviation or standard error, first and third 
quartiles, minimum, and maximum) at all scheduled visits will be calculated. Subject 
incidence, exposure-adjusted subject incidence rate, and yearly Kaplan Meier (K-
M) estimates of positively reviewed events (by an independent external CEC) will be 
summarized for both the OLE study period and combined parent and OLE study 
periods. All deaths will be summarized by cardiovascular death (including 
coronary heart disease death), non-cardiovascular death and undetermined cause 
of death. A sensitivity analysis will be performed for the following composite 
endpoints:

 
time to cardiovascular death, myocardial infarction, hospitalization for 
unstable angina, stroke, or coronary revascularization, whichever occurs 
first  


occurs first 
In this analysis, cardiovascular events which occurred during the gap between 
subjects End of Study date in the parent study and OLE study enrolment date will 
be included in the time to event analysis.

Safety Analyses 
9.6.1 
Safety Analysis of Low LDL-C 
The safety analyses (TEAE and serious TEAE) will be summarized for subjects with any 
postbaseline LDL-C and all postbaseline LDL-C with the cutoffs of < 25 mg/dL, < 40 
mg/dL and ≥ 40 mg/dL for the OLE study period using the OLE safety analysis set. 
In addition, the safety analyses will be summarized in subjects with 2 consecutive 
postbaseline LDL-C < 25 mg/dL and LDL-C < 40 mg/dL separated by at least 21 days. 
9.6.2 
Vital Signs 
Systolic and diastolic blood pressure and heart rate will be summarized using descriptive 
statistics at each scheduled visit based on the OLE Safety Analysis Set for the OLE 
study period. 
  
9.6.3 
Exposure to Investigational Product 
Descriptive statistics will be produced to describe the exposure to investigational product 
for both the overall OLE study period and combined parent and OLE study 
periods using the OLE Safety Analysis Set. 
9.6.4 
Exposure to Other Protocol-specified Treatment 
The number and proportion of subjects receiving protocol specified lipid regulating 
medications captured on the related concomitant medication eCRF will be 
summarized. The subject incidence of changes in protocol specified background lipid 
regulating medications during the treatment period will also be provided for the overall 
OLE study period using the OLE Safety Analysis Set (Appendix D). 
9.6.5 
Exposure to Concomitant Medication 
The number and proportion of subjects receiving therapies of interest will be 
summarized by preferred term or category as coded by the World Health Organization 
Drug (WHO DRUG) dictionary using the OLE Safety Analysis Set.

Other Analyses 
A listing will be provided for events which occurred in the time between the subject’s 
EOS date in the parent study and the enrolment date of the OLE (recorded on the 
medical history eCRF for the OLE).

Changes From Protocol-specified Analyses 
Removed long-term safety analysis set and related analysis from SAP. 
Rationale: The pre-specified planned analyses in the SAP focus on the long term 
safety data in the subjects who enrolled into this OLE study (i.e., OLE safety 
analysis set) rather than the long-term safety analysis set which also includes the 
subjects from the parent study who did not enroll into this OLE study.

Appendix A.  Analytical Study Week Assignments 
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. 
If there is more than one record in a given analytical window, the analytical record for 
that scheduled visit will be defined as the record closest to the scheduled visit day 
(7 days x Number of Study Weeks + 1) for that scheduled visit. If two records are 
equidistant from the scheduled visit day, then the earlier record will be chosen. If there 
are multiple records on the same day, the last record will be used.
