Supplemental Methods
Inclusion Criteria
Patients meeting all of the following criteria will be considered for enrollment into the
study:
I 01. Patients with heterozygous familial hypercholesterolemia (HeFH)* with or
without established coronary heart disease (CHD) or CHD risk equivalents who are

at least 4 weeks prior to the screening visit (Week -3) with or without other lipid
lowering therapy (LLT);
OR
I 02. Patients with hypercholesterolemia and established CHD or CHD risk
equivalents (see below for definitions) who are not adequately controlled with a
maximally tolerated stable daily dose of statin** for at least 4 weeks prior to the
screening visit (Week -3) with or without LLT.
I 03. Signed written informed consent.
*Diagnosis of HeFH must be made either by genotyping or by clinical criteria. For
those patients not genotyped, the clinical diagnosis may be based on either the
World Health Organisation/Dutch Lipid Clinical Network criteria with a score > 8
points or the Simon Broome register diagnostic criteria with a criterion for definite
FH.
** Definition of maximally tolerated dose (any of the following are acceptable):
11
- Rosuvastatin 20 mg or 40 mg daily
- Atorvastatin 40 mg or 80 mg daily
- Simvastatin 80 mg daily (if already on this dose for >1 year)
- Patients not able to be on any of the above statin doses, should be treated with the
dose of daily atorvastatin, rosuvastatin or simvastatin which is considered
appropriate for the patient as per the investigator's judgment or concerns. Some
examples of acceptable reasons for a patient taking a lower statin dose include, but
are not limited to: adverse effects on higher doses, advanced age, low body mass
index, regional practices, local prescribing information, concomitant medications, co-
morbid conditions such as impaired glucose tolerance/impaired fasting glucose.
A) Documented history of CHD (includes one or more of the following):
i) Acute myocardial infarction (MI).
ii) Silent MI.
iii) Unstable angina.
iv) Coronary revascularization procedure (eg, percutaneous coronary intervention
[PCI] or coronary artery bypass graft surgery [CABG]).
v) Clinically significant CHD diagnosed by invasive or non-invasive testing (such as
coronary angiography, stress test using treadmill, stress echocardiography or
nuclear imaging).
B) CHD risk equivalents (includes one or more of the following 4 criteria):

either leg at rest, OR
b) History of intermittent claudication (muscle discomfort in the lower limb that is both
reproducible and produced by exercise and relieved by rest within 10 minutes)
TOGETHER WITH endovascular procedure or surgical intervention in one or both
legs because of atherosclerotic disease OR
c) History of critical limb ischemia TOGETHER WITH thrombolysis, endovascular
procedure or surgical intervention in one or both legs because of atherosclerotic
disease.
ii) Documented previous ischemic stroke with a focal ischemic neurological deficit
that persisted more than 24 hours, considered as being of atherothrombotic origin.
CT or MRI must have been performed to rule out hemorrhage and non-ischemic
neurological disease.

glomerular flow rate (eGFR) <60 mL per min per 1.73 m2 for 3 months or more,
including the screening visit
iv) Known history of diabetes mellitus AND 2 or more additional risk factors (as listed
below):
13
a) History of hypertension (established on antihypertensive medication)
b) Documented history of ankle-brachial index ≤0.90

must be amenorrheic for at least 12 months.
19
Randomization
The randomized list of treatment kit numbers was computer generated by Sanofi and
provided to a central allocation system. Study patients, investigators and study site
personnel remained blinded to treatment allocation until after completion of the trial.
Randomization was stratified according to: (1) heterozygous familial
hypercholesterolemia (HeFH) status, (2) prior history of myocardial infarction (MI) or
ischemic stroke, (3) background statin treatment (atorvastatin 40-80 mg per day or
rosuvastatin 20-40 mg per day vs. simvastatin whatever the daily dose, atorvastatin
<40 mg per day or rosuvastatin <20 mg per day), and (4) geographic region.
Active drug and placebo were identically packaged to protect the blind. Injections
could be performed at home by the patient or a designated caregiver. Training for
the person performing the injection was provided during screening.
Extent of Study Drug Exposure
Total exposure was assessed by (1) duration of study drug exposure in weeks,
defined as: (last double-blind injection date +14 day, minus first double-blind injection
date)/7, regardless of unplanned intermittent discontinuations, and (2) the total
number of injections by patient.
Adherence to Study Treatment
The overall adherence (mean and median) for injections is defined for each patient
as: 100 – (% days with under-planned dosing + % days with above-planned dosing).
Under-planned and above-planned dosing is defined by considering that injections
should be performed every 2 weeks (±3 days as per protocol).
20
Laboratory Assessments
Blood samples were obtained after a 10-hour overnight fast (water only). Analysis of
the lipid samples and clinical laboratory safety tests were performed by a central
laboratory (Covance Central Laboratory, Indianapolis, IN, USA, and Geneva,
Switzerland). Total cholesterol, triglycerides, and HDL cholesterol levels in serum
were determined using Centers for Disease Control and Prevention National Heart
Lung Blood Institute Lipid Standardization Program assays. LDL cholesterol was
calculated using the Friedewald formula at all sampling points. LDL cholesterol was
also measured via ultracentrifugation and precipitation (beta-quantification) by the
central laboratory at weeks 0, 12, 24, 52, and 78, and in cases where triglyceride
values were >400 mg per deciliter (4.52 mmol per liter). Apolipoprotein B,
apolipoprotein A1, and lipoprotein(a) levels in serum were determined using
immunonephelometry. Total and free PCSK9 concentrations in serum were
quantified with validated enzyme-linked immunosorbent assay method (Regeneron
Pharmaceuticals Inc., Tarrytown, NY, USA). Investigators remained blind to
laboratory data (except clinical safety tests) throughout the study.
Additional Statistical Analyses and Secondary Efficacy Endpoints
An on-treatment analysis was also performed as a secondary endpoint, including
only LDL cholesterol measurements taken while the patient was receiving study
treatment. A sensitivity analysis based on a pattern mixture model was also
conducted to evaluate the impact of missing data on the primary endpoint; in this
approach, missing calculated LDL cholesterol values during the on-treatment period
21
were multiply imputed using a model assuming “missing at random”; missing
calculated LDL cholesterol values during the post-treatment period were multiply
imputed using random draws from a normal distribution where the mean was equal
to subject’s own baseline value.
Secondary endpoints were tested in a hierarchical order as shown below:
• The percent change in calculated low-density lipoprotein cholesterol (LDL
cholesterol) from baseline to Week 24 in the modified intent-to-treat (mITT)
population, using all LDL cholesterol values at sampling points during the efficacy
treatment period (on-treatment).
• The percent change in calculated LDL cholesterol from baseline to Week 12 (ITT).
• The percent change in calculated LDL cholesterol from baseline to Week 12 (on-
treatment).
• The percent change in measured LDL cholesterol from baseline to Week 24 (ITT).
• The percent change in apolipoprotein B from baseline to Week 24 (ITT).

22
The percent change in Apo B from baseline to Week 12 (ITT).
• The percent change in non-HDL-C from baseline to Week 12 (ITT).
• The percent change in total-C from baseline to Week 12 (ITT).

LDL cholesterol < 100 mg per deciliter (2.59 mmol per liter) at Week 24 (ITT)
• The proportion of very high CV risk patients reaching calculated LDL cholesterol <
70 mg per deciliter (1.81 mmol per liter) or high CV risk patients reaching calculated
LDL cholesterol < 100 mg per deciliter (2.59 mmol per liter) at Week 24 (on-
treatment).
• The proportion of patients reaching calculated LDL cholesterol < 70 mg per deciliter
(1.81 mmol per liter) at Week 24 (ITT).
• The proportion of patients reaching calculated LDL cholesterol < 70 mg per deciliter
(1.81 mmol per liter) at Week 24 (on-treatment).
• The percent change in lipoprotein (a) [Lp(a)] from baseline to Week 24(ITT).
• The percent change in HDL-C from baseline to Week 24(ITT).
• The percent change in fasting TG from baseline to Week 24 (ITT).
• The percent change in apolipoprotein A1 from baseline to Week 24 (ITT).
• The percent change in Lp (a) from baseline to Week 12 (ITT).
23
• The percent change in HDL-C from baseline to Week 12 (ITT).
• The percent change in fasting triglycerides from baseline to Week 12 (ITT).
• The percent change in apolipoprotein A-1 from baseline to Week 12 (ITT).
* CV risk categories are defined for the study as high risk and very high risk as
follows:
• Very high CV risk patients are defined as patients with HeFH with CHD or CHD risk
equivalents or non-FH.
• High CV risk patients are defined as HeFH patients without CHD or CHD risk
equivalents.
The other secondary efficacy endpoints (data not reported for all) are:
• The percent change in calculated LDL cholesterol from baseline to Weeks 52 and
78 (ITT).
• The proportion of very high CV risk patients reaching calculated LDL cholesterol <
70 mg per deciliter (1.81mmol per liter) or high CV risk patients reaching calculated
LDL cholesterol < 100 mg per deciliter (2.59 mmol per liter) at Weeks 12, 52, and 78
(ITT).
• The proportion of patients reaching calculated LDL cholesterol < 100 mg per
deciliter (2.59 mmol per liter) at Weeks 12, 24, 52, and 78 (ITT).

Monitoring and Laboratory Alert Related to Two Consecutive Calculated LDL
cholesterol <25 mg per deciliter (0.65 mmol per liter)
Patients who achieve two consecutive calculated LDL cholesterol values <25 mg per
deciliter (0.65 mmol per liter) during the study were monitored by a dedicated data
monitoring committee (DMC) member and independent physician. At the discretion
of the DMC member following consultation with the independent physician, an alert
was sent to the site (sham alerts also used to preserve the blind), so the investigator
would call the patient about occurrences of adverse events and decide whether the
patient should be requested to rapidly have an unscheduled site visit, or assessment
could be done at the next scheduled visit. At the site visit, the investigator had to
assess whether the patient needed additional work-up, should see a specialist and
whether the study treatment should be temporarily or permanently discontinued.

Prespecified Definitions of Cardiovascular Events
Death
All deaths will be categorized as Cardiovascular, non-Cardiovascular or
Undetermined based on the definitions below. In addition, all deaths will also be
categorized as Coronary Heart Disease Death and further sub-typed based on the
specific Cardiovascular and non-Cardiovascular categories defined below.
Cardiovascular Death:
Cardiovascular Death is defined as death resulting from an acute myocardial
infarction, sudden cardiac death, death due to heart failure, death due to stroke,
death due to cardiovascular (CV) procedures, death due to CV hemorrhage, and
death due to other cardiovascular causes. Coronary Heart Disease Death is defined
as the subset of Cardiovascular deaths for which there is a clear relationship to
underlying coronary heart disease, including death secondary to acute MI, sudden
death, heart failure, complication of a coronary revascularization procedure
performed for symptoms, coronary disease progression, or new myocardial ischemia
where the cause of death is clearly related to the procedure, unobserved and
unexpected death, and other death that cannot definitely be attributed to a
nonvascular cause.
1. Death due to Acute Myocardial Infarction:
Death by any mechanism (arrhythmia, heart failure, low output) within 30 days after
a myocardial infarction (MI) related to the immediate consequences of the
myocardial infarction, such as progressive congestive heart failure (CHF),
27
inadequate cardiac output, or refractory arrhythmia. If these events occur after a
“break” (e.g., a CHF and arrhythmia free period of at least a week), they should be
designated by the immediate cause, even though the MI may have increased the risk
of that event (e.g., late arrhythmic death becomes more likely after an acute
myocardial infarction (AMI)). The acute myocardial infarction should be verified to the
extent possible by the diagnostic criteria outlined for acute myocardial infarction or
by autopsy findings showing recent myocardial infarction or recent coronary
thrombus. Sudden cardiac death, if accompanied by symptoms suggestive of
myocardial ischemia, new ST elevation, new LBBB, or evidence of fresh thrombus
by coronary angiography and/or at autopsy should be considered death resulting
from an acute myocardial infarction, even if death occurs before blood samples or
12-lead electrocardiogram (ECG) could be obtained, or at a time before the
appearance of cardiac biomarkers in the blood. Death resulting from a procedure to
treat a myocardial infarction percutaneous coronary intervention (PCI), coronary
artery bypass graft surgery (CABG), or to treat a complication resulting from
myocardial infarction, should also be considered death due to acute MI. Death
resulting from an elective coronary procedure to treat myocardial ischemia (i.e.,
chronic stable angina) or death due to a MI that occurs as a direct consequence of a
CV investigation/procedure/operation should be considered as a death due to a CV
procedure.
2. Sudden Cardiac Death:
Death that occurs unexpectedly, not following an acute AMI, and includes the
following deaths:
28
a. Death witnessed and occurring without new or worsening symptoms.
b. Death witnessed within 60 minutes of the onset of new or worsening
cardiac symptoms, unless documented (i.e. by ECG or other objective) to be
due to acute myocardial infarction.
c. Death witnessed and attributed to an identified arrhythmia (e.g., captured
on an electrocardiographic (ECG) recording, witnessed on a monitor, or
unwitnessed but found on implantable cardioverter-defibrillator review).
d. Death after unsuccessful resuscitation from cardiac arrest.
e. Death after successful resuscitation from cardiac arrest and without
identification of a non-cardiac etiology.
f. Unwitnessed death without other cause of death (information regarding the
patient’s clinical status preceding death should be provided, if available).
General Considerations
A subject seen alive and clinically stable 24 hours prior to being found dead without
any evidence or information of a specific cause of death should be classified as
“sudden cardiac death.”
Typical scenarios include:
Subject well the previous day but found dead in bed the next day
Subject found dead at home on the couch with the television on
29
Deaths for which there is no information beyond “Patient found dead at home” may
be classified as “death due to other cardiovascular causes”.
3. Death due to Heart Failure or Cardiogenic Shock:
Death due to Congestive Heart Failure refers to a death in association with clinically
worsening symptoms and/or signs of heart failure not following an acute MI. Deaths
due to heart failure can have various etiologies, including single or recurrent
myocardial infarctions, ischemic or non-ischemic cardiomyopathy, hypertension, or
valvular disease. Cardiogenic shock not occurring in the context of an acute
myocardial infarction or as the consequence of an arrhythmia occurring in the
absence of worsening heart failure is defined as systolic blood pressure (SBP) < 90
mm Hg for greater than 1 hour, not responsive to fluid resuscitation and/or heart rate
correction, and felt to be secondary to cardiac dysfunction and associated with at
least one of the following signs of hypoperfusion:
Cool, clammy skin or
Oliguria (urine output < 30 mL/hour) or
Altered sensorium or Cardiac index < 2.2 L/min/m²
Cardiogenic shock can also be defined if SBP < 90 mm Hg and increases to ≥ 90
mm Hg in less than 1 hour with positive inotropic or vasopressor agents alone
and/or with mechanical support.
30
4. Death due to Stroke refers to death after a stroke that is either a direct
consequence of the stroke or a complication of the stroke. Acute stroke should be
verified to the extent possible by the diagnostic criteria outlined for stroke.
5. Death due to Cardiovascular Procedures refers to death caused by the
immediate complications of a cardiac procedure and excludes death resulting from
procedures to treat an acute MI or the complications resulting from an acute MI.
6. Death due to Cardiovascular Hemorrhage refers to death related to
hemorrhage such as a non-stroke intracranial hemorrhage, non-procedural or non-
traumatic vascular rupture (e.g., aortic aneurysm), or hemorrhage causing cardiac
tamponade.
7. Death due to Other Cardiovascular Causes refers to a cardiovascular death not
included in the above categories (e.g., pulmonary embolism or peripheral arterial
disease).
Non-cardiovascular Death: Non-cardiovascular death is defined as any death that
is not thought to be due to a cardiovascular cause. The following categories may be
collected:
Non-Malignant Causes
Pulmonary
Renal
Gastrointestinal
31
Hepatobiliary
Pancreatic
Infection (includes sepsis)
Non-infectious (e.g., systemic inflammatory response syndrome (SIRS))
Hemorrhage*, excluding hemorrhagic strokes and bleeding in the setting of
coronary revascularization
Non-cardiovascular procedure or surgery
Accidental (e.g., physical accidents or drug overdose) or trauma
Suicide
Prescription Drug Error (e.g., prescribed drug overdose, use of inappropriate
drug, or drug-drug interaction)
Neurological process that is not a stroke or hemorrhage
*Examples: Death due to GI bleeding is not considered a CV death. Death due to
retroperitoneal hematoma following PCI is considered CV death. Death due to
intracerebral hemorrhage is considered CV death.
Malignant Causes
Death results directly from the cancer;
OR
32
Death results from a complication of the cancer (e.g. infection, complication of
surgery / chemotherapy / radiotherapy);
OR
Death results from withdrawal of other therapies because of concerns relating
to the poor prognosis associated with the cancer
Cancer deaths may arise from cancers that were present prior to randomization or
which developed subsequently should be further classified (worsening prior
malignancy; new malignancy).
Undetermined Cause of Death refers to a death not attributable to one of the above
categories of cardiovascular death or to a non-cardiovascular cause, due to absence
of any information (e.g., the only available information is “patient died”). The use of
this category of death is discouraged and should apply to a minimal number of cases
when no information at all on the circumstances of death are available (i.e. found on
obituary of local newspaper). In all circumstances the reviewer will use all available
information to attribute to one of the categories based on best clinical judgment.
MYOCARDIAL INFARCTION (MI)
Acute Myocardial Infarction - The term acute myocardial infarction (MI) refers to
evidence of myocardial necrosis in a clinical setting consistent with acute myocardial
ischemia. Under these conditions any one of the following criteria meets the
diagnosis for MI:
33
1. Detection of a rise and/or fall of cardiac biomarker values [preferably cardiac
troponin (cTn)] with at least one value above the upper reference limit (URL) and
with at least one of the following:
Symptoms of ischemia.
New or presumed new significant ST-segment–T wave (ST–T) changes or new
left bundle branch block (LBBB). Development of pathological Q waves in the
ECG.
Imaging evidence of new loss of viable myocardium or new regional wall motion
abnormality.
Identification of an intracoronary thrombus by angiography or autopsy.
2. Cardiac death with symptoms suggestive of myocardial ischaemia and
presumed new ischaemic ECG changes or new LBBB, but death occurred before
cardiac biomarkers were obtained, or before cardiac biomarker values would be
increased.
3. Percutaneous coronary intervention (PCI) related MI is defined by elevation of
cTn values (>5 x URL) occurring within 48h of the procedure in patients with
normal baseline values (≤URL) or a rise of cTn values >20% if the baseline values
are elevated and are stable or falling. In addition, at least one of the following is
required
symptoms suggestive of myocardial ischaemia
new ischaemic ECG changes
34
angiographic findings consistent with a procedural complication
imaging demonstration of new loss of viable myocardium or new regional wall
motion abnormality
4. Stent thrombosis associated with MI when detected by coronary angiography or
autopsy in the setting of evidence of myocardial ischaemia and with a rise and/or
fall cardiac biomarker values with at least one value above the Upper Reference
Limit (URL).
5. Coronary artery bypass grafting (CABG) related MI is defined by elevation of
troponin values (>10 x URL) occurring within 48h of the procedure in patients with
normal baseline cTn values (≤URL). In addition at least one of the following is
required
new pathological Q waves or new LBBB
angiographic documented new graft or new native coronary artery occlusion
imaging evidence of new loss of viable myocardium or new regional wall motion
abnormality.
Cardiac troponin is the preferred biomarker for diagnosis of MI. In absence of
troponin, CK-MB will be used.
Silent Myocardial Infarction
Asymptomatic patients who develop new pathologic Q wave criteria for MI detected
during routine ECG follow-up, or reveal evidence of MI by cardiac imaging, that
35
cannot be directly attributed to a coronary revascularization procedure, are termed
‘silent MI”. Any one of the following criteria meets the diagnosis:
• Pathological Q waves with or without symptoms in the absence of non-ischemic
causes.
• Imaging evidence of a region of loss of viable myocardium that is thinned and fails
to contract, in the absence of a non-ischaemic cause.
• Pathological findings of a prior MI All MI events will be classified by Universal MI
definition subtypes as follows:
Type 1
Spontaneous myocardial infarction related to atherosclerotic plaque rupture,
ulceration, fissuring, erosion, or dissection with resulting intraluminal thrombus
in one or more of the coronary arteries leading to decreased myocardial blood
flow or distal platelet emboli with ensuing myocyte necrosis. The patient may
have underlying severe CAD but on occasion non-obstructive or no CAD
Type 2
In instances of myocardial injury with necrosis where a condition other than
CAD contributes to an imbalance between myocardial oxygen supply and/or
demand, e.g. coronary endothelial dysfunction, coronary artery spasm,
coronary embolism, tachy/brady-arrhythmias, anemia, respiratory failure,
hypotension, and hypertension with or without LVH.
Type 3
36
Cardiac death with symptoms suggestive of myocardial ischemia and
presumed new ischemic ECG changes or new LBBB, but death occurring
before blood samples could be obtained, before cardiac biomarker could rise,
or in rare cases cardiac biomarkers were not collected.
Type 4a
Myocardial infarction associated with PCI
Type 4b
Myocardial infarction associated with stent thrombosis
Type 4c
Myocardial infarction associated with restenosis (restenosis is the only
angiographic explanation)
Type 5
Myocardial infarction associated with CABG
All MI events will be sub-classified into STEMI vs. NSTEMI as follows:
STEMI
New ST elevation at the J point in two contiguous leads with the cut-points: ≥0.1
mV in all leads other than leads V2–V3 where the following cut points apply: ≥0.2
mV in men ≥40 years; ≥0.25 mV in men <40 years, or ≥0.15 mV in women
If ECG does not meet STEMI criteria will be classified as NSTEMI
37
If ECGs are unavailable or uninterpretable the MI will be classified as unknown
All MI events will be sub-classified into Q wave vs. Non Q wave MI as follows:
Criteria for abnormal Q-waves are any one of:
Any Q wave in leadsV2–V3 ≥0.02 sec or QS complex in leadsV2 andV3.
Q wave ≥0.03 sec and ≥0.1 mV deep or QS complex in leads I, II, aVL, aVF or
V4–V6 in any two leads of a contiguous lead grouping (I, aVL; V1–V6; II, III, aVF).
a. The same criteria are used for supplemental leads V7-V9.
R wave ≥0.04 sec in V1–V2 and R/S ≥1 with a concordant positive T wave in
absence of conduction defect
If Q-waves criteria are not met, MI is classified as non-Q-wave MI
If ECGs are unavailable or uninterpretable the MI will be classified as unknown
Unstable angina (UA) Requiring Hospitalization
A diagnosis of an unstable angina (new ACS event without elevation in cardiac
biomarkers) that meets the primary endpoint requires the following:
• Admission to hospital or emergency room (until at least next calendar day) with
symptoms presumed to be caused by myocardial ischemia with an accelerating
tempo in the prior 48 hrs and/or prolonged (at least 20 min) rest chest discomfort
AND
38
• New high-risk ECG findings consistent with ischemia (or presumed new if no prior
ECG available), as defined below:
a) New or presumed new ST depression >0.5mm in 2 contiguous leads or T wave
inversion >1mm in leads with prominent R wave or R/S >1 in 2 contiguous leads.
b) New or presumed new ST elevation at the J point in > 2 contiguous leads >0.2mV
in V2 or V3 in men or >0.15 mV in women in V2 or V3 or >0.1mV in other leads.
c) LBBB (new or presumed new).
AND
• Definite contemporary* evidence of angiographically significant coronary disease
as demonstrated by:
- Need for coronary revascularization procedure (PCI or CABG) excluding those
performed to treat only restenosis lesion(s) at previous PCI site(s)
OR
- Angiographic evidence of at least one significant (> 70%) epicardial coronary
stenosis not due to restenosis at previous PCI site.
*The coronary revascularization procedure or the diagnostic angiography must have
been performed during the hospitalization for that event.
Stroke
39
Stroke is defined as an acute episode of focal or global neurological dysfunction
caused by central nervous system (CNS) vascular injury as a result of hemorrhage
or infarction. CNS includes brain, spinal cord and retina.
Classification:
1. Ischemic Stroke
Ischemic stroke is defined as an acute episode of focal cerebral, spinal, or retinal
dysfunction caused by CNS infarction. Evidence of infarction is defined as
A. Pathological, imaging, or other objective evidence of acute cerebral, spinal
cord, or retinal focal ischemic injury in a defined vascular distribution; or
B. In absence of the above (i.e. imaging or autopsy unavailable), clinical
evidence of cerebral, spinal cord, or retinal focal ischemic injury is based on
symptoms persisting ≥24 hours or until death, and other etiologies excluded.
C. Note, Hemorrhagic infarction, defined as a parenchymal hemorrhage after
CNS infarction, is considered an ischemic stroke.
D. Ischemic strokes may be further classified according to most likely etiology
(example large artery atherosclerosis, cardio-embolic, etc.)
2. Cerebral Hemorrhage
Hemorrhages in the CNS are classified as stroke if they are nontraumatic caused by
a vascular event, and result in injury to the CNS. In contrast, traumatic hemorrhages
will not be characterized as stroke. Subdural hematoma will not be classified as a
40
stroke. The diagnoses included in this section are intracerebral hemorrhage
(intraparenchymal and intraventricular) and subarachnoid hemorrhage (both
aneurysmal and nonaneurysmal).
A. Stroke caused by intracerebral hemorrhage
Rapidly developing clinical signs of neurological dysfunction (focal or global)
attributable to a focal collection of blood within the brain parenchyma or
ventricular system that is not caused by trauma.
B. Stroke caused by subarachnoid hemorrhage
Rapidly developing signs of neurological dysfunction (focal or global) and/or
headache because of bleeding into the subarachnoid space (the space
between the arachnoid membrane and the pia mater of the brain or spinal
cord), which is not caused by trauma.
C. Hemorrhages may be further classified according to location (example,
supratentorial, subtentorial etc.)
3. Stroke not otherwise specified
An episode of acute neurological dysfunction presumed to be caused by ischemia or
hemorrhage, persisting ≥24 hours or until death, but without sufficient evidence to be
classified as one of the above.
Congestive Heart failure (CHF) requiring hospitalization
A Congestive Heart Failure Event requiring hospitalization is defined as:
41
A. An event that meets ALL of the following criteria:
1. The patient is admitted to the hospital or emergency room (until at least the
next calendar day) with a primary diagnosis of CHF
2. The patient exhibits documented new or worsening symptoms due to CHF
on presentation, including at least ONE of the following:
a. Dyspnea (dyspnea with exertion, dyspnea at rest, orthopnea, paroxysmal
nocturnal dyspnea)
b. Decreased exercise tolerance
c. Fatigue
d. Other symptoms of worsened end-organ perfusion or volume overload.
3. The patient has objective evidence of new or worsening CHF, consisting of
at least TWO physical examination findings OR one physical examination
finding and at least ONE laboratory/imaging/hemodynamic criterion),
including:
a. Physical examination findings considered to be due to heart failure,
including new or worsened:
i. Peripheral edema
ii. Increasing abdominal distention or ascites (in the absence of primary
hepatic disease)
42
iii. Pulmonary rales/crackles/crepitations
iv. Increased jugular venous pressure and/or hepatojugular reflux
v. S3 gallop
vi. Clinically significant or rapid weight gain thought to be related to fluid
retention
b. Laboratory, imaging or hemodynamic evidence of new or worsening CHF,
including:
i. Increased B-type natriuretic peptide (BNP)/ N-terminal pro-BNP
(NTproBNP) concentrations consistent with decompensation of heart failure.
In patients with chronically elevated natriuretic peptides, a significant increase
should be noted above baseline.
ii. Radiological evidence of pulmonary congestion
iii. Hemodynamic evidence from right heart catheterization (e.g. elevated
pulmonary capillary wedge pressure, elevated central venous pressure, or low
cardiac index) or from left heart catheterization (elevated left ventricular end-
diastolic pressure)
5. The patient receives initiation or intensification of treatment specifically for
CHF, including at least ONE of the following:
a. Significant augmentation in oral diuretic therapy
43
b. Intravenous diuretic, inotrope, or vasodilator therapy
c. Mechanical or surgical intervention, including:
i. Mechanical circulatory support (e.g., intra-aortic balloon pump, ventricular
assist device)
ii. Mechanical fluid removal (e.g., ultrafiltration, hemofiltration, dialysis)
Ischemia-driven Coronary revascularization procedures
‘Coronary revascularization’ includes all coronary revascularization procedures
(PCI/CABG) performed during the study, and driven by new or presumed new
myocardial ischemia since randomization (categories 1 and 2 described below), and
excluding procedures performed only to treat restenosis lesion(s) at prior PCI
sites(s).
Reasons for the PCI/CABG will be collected in the CRF as follows:
(1) driven by acute ischemia (ACS)
(2) driven by new/progressive (i.e. not present at randomization or with
indication of progression since randomization), chronic (i.e. not in context of
ACS) ischemia, evidenced by new/progressive symptoms (angina or
equivalent) or new/progressive functional testing abnormalities (e.g. stress
test, imaging)
(3) other (i.e. not driven by ACS event, or new/progressive chronic ischemia).
44
PCI involves a catheter-based tool (e.g., balloon catheters, cutting balloons,
atherectomy devices, lasers, bare metal stents, and drug-eluting stents) that
improves myocardial blood flow by increasing the luminal area at a site of an
obstructive coronary lesion. Coronary artery bypass grafting (CABG) is an open
surgical procedure designed to improve myocardial blood flow by providing a conduit
(arterial, venous, or synthetic) for blood flow distal to an obstructive coronary lesion.
Insertion of a guidewire through a coronary guide catheter into a coronary vessel or
aortocoronary bypass graft for the purpose of percutaneous coronary intervention
(PCI) is considered as a PCI (since there is an intention to perform a PCI). However,
insertion of a guidewire in order to assess the severity of intermediate lesions with
the use of intravascular ultrasound, Doppler flow velocity, or fractional flow reserve,
will NOT be considered PCI.

event categories which also form the endpoint for the ODYSSEY OUTCOMES study: CHD death,
Non-fatal MI, fatal and non-fatal ischemic stroke, and unstable angina requiring hospitalization.8
“Unstable angina requiring hospitalization” is limited to the unstable angina events with definite
evidence of progression of the ischemic condition (strict criteria). Congestive heart failure requiring
hospitalization and ischemia driven coronary revascularization procedure are not included in the post
hoc analysis. Rates of all adjudicated CV events are shown in Table 3. When these two types of
event are counted the number of patients with CV events is 4.6% (n=72) alirocumab vs 5.1% (n=40)
placebo; in this case, no statistically significant difference between groups was observed.
Patients were censored at the end of the treatment-emergent adverse event period (defined as the
time from first to last injection of study treatment + 70 days).

* Plus–minus values are least-squares means ±SE, unless otherwise indicated. Only patients who
were receiving study treatment and had an evaluable primary efficacy endpoint during the efficacy
period were included in the on-treatment analysis. Patients were defined as receiving study treatment
during the period from the first dose of study treatment up until 21 days after last dose. The primary
efficacy endpoint was defined as evaluable in a patient when a calculated LDL cholesterol value was
available at both baseline and during the efficacy treatment period within one of the analysis windows
up to Week 24. Least-squares means, SE and p-value taken from mixed-effect model with repeated
measures analysis (except for endpoints noted by footnote symbols below). The p-values are
significant according to the fixed hierarchical approach used to ensure control of the overall type-1
error rate at the 0.05 level. To convert cholesterol to mmol per liter, multiply by 0.02586. CI denotes
confidence interval, HDL, high-density lipoprotein, LDL, low-density lipoprotein, SE, standard error.
‡Multiple imputation followed by logistic regression: combined estimate for proportion of patients is
obtained by averaging out all the imputed proportions of patients reaching the level of interest.

*This sensitivity analysis has been conducted to further evaluate the impact of missing data on the
primary endpoint: in this approach, missing calculated LDL cholesterol values during the “on-
treatment” period were multiply imputed using a model assuming Missing At Random and missing
calculated LDL cholesterol values during the post-treatment period were multiply imputed using
random draws from a normal distribution, with mean equal to subject’s own baseline value. To convert
cholesterol to mmol per liter, multiply by 0.02586. CI denotes confidence interval, LDL, low-density
lipoprotein, SD, standard deviation, SE, standard error.
