*PTC Definition: 
All complaints that triggered an investigation by the Device 
Department will be categorized as device-related, patient- related, 
undetermined, or not related to device nor patient. In this study, 
a PTC is defined as any complaint reported on the Patient 
Complaint form that triggered an investigation by the Device 
Department and was categorized as either device-related,  patient- 
related or undetermined,  whether or not associated with an AE. Of 
note, the complaints categorized as not related to device nor patient 
will not be considered as a PTC. This definition will be used for both 
primary and secondary endpoints. 
* In case a PTC is associated with the occurrence of an AE, the AE 
must be documented on an AE page in the electronic case report 
form (e-CRF) and the PTC must be described. In case a PTC is 
associated with the occurrence of a SAE, the SAE must be reported 
to the Monitoring Team in accordance with the SAE reporting 
procedures. 
ASSESSMENT SCHEDULE 
The study will consist of the following visits: 
• 
Visit 1 (between Week -2 and Week 0), screening visit, 
on-site visit. 
• 
Visit 2 (Week 0, D1): randomization, baseline visit, on-site 
visit. 
• 
Visits 3 through 11 (Week 1 through Week 15):  
- 
Visits 3, 4, 5, 9, 10, and 11: PK sampling will be 
collected at these visits. These visits may be 
performed on site or as home-visits. 
- 
Visits 6 and 7 (Weeks 4 and 8): These visits may be 
performed on site or as home-visits. 
•

STATISTICAL CONSIDERATIONS 
 
Sample size determination 
No formal sample size was calculated for this study: sample size is 
based on empirical considerations.  
Considering a drop-out rate of 10% it is proposed to randomize 
66 patients overall (33 in each group) in order to ensure 
60 evaluable patients overall (30 in each group) resulting in

180 unsupervised planned injections using SYDNEY. Patients in the 
AI group will switch to SYDNEY group at the time of the second 
injection; therefore, it will ensure to have 60 evaluable patients using 
SYDNEY for the 2nd, 3rd and 4th unsupervised injections. 
With 60 evaluable patients using SYDNEY, a total of 
180 unsupervised injections is expected to be achieved during the 
study. Expecting a maximum of 3 observed PTC over the 
180 injections (observed PTC rate of 1.67%) with SYDNEY, the 
upper bound of the 2-sided 95% confidence interval (CI) calculated 
with the Wilson score method will be no higher than 5.2%. 
Analysis population 
The primary endpoint will be analyzed on the safety population of the 
single-arm period that will consist of all randomized patients who 
continue in the single-arm period (from Week 4, to Week 16), and 
receive at least 1 dose or part of a dose of Investigational Medicinal 
Product (IMP ) during this period.  
Analysis of the primary endpoint 
The primary endpoint (ie, number (%) and type of 
SYDNEY-associated PTCs at the unsupervised injections) will be 
described on the safety population for the single-arm period. The 
number and % of PTCs will be provided with the 95% CI using 
Wilson score method. If applicable, the number of PTCs per patient 
will be described. 
Analysis of secondary endpoints 
All secondary device-related endpoints will be analyzed on the safety 
population using descriptive statistics. In addition, 95% CI for the 
number of PTCs, number and % of patients with any PTCs will be 
provided using Wilson score method.  
Pharmacokinetics 
PK parameters and levels of PCSK9 (total and free) will be 
summarized descriptively by auto-injector device group. 
After the first administration only, for log-transformed maximum 
plasma concentration (Cmax), area under the curve concentration 
versus time curve extrapolated to infinity (AUC0-tau) and trough 
concentration (Ctrough), the difference between auto-injector devices 
will be assessed using a linear fixed effects model. 
Estimate and 90% CI for the ratio of geometric means 
(SYDNEY/current AI) will be computed for Cmax,  
AUC0-tau and Ctrough.   
Anti-drug antibodies 
Results of ADA will be summarized by auto-injector device group 
using descriptive statistics. 
Pharmacodynamics 
Percent and absolute change from baseline in LDL-C will be 
summarized descriptively for each auto-injector device. 
At Week 4 only, statistical analyses will compare auto-injector 
devices using an ANCOVA model to determine the estimates and 
95% confidence intervals for the difference between means of 
percent LDL-C change for AI versus SYDNEY.

Safety and tolerability 
The safety analysis will be based on the review of the individual data 
and descriptive statistics. 
 
Adverse events will be classified using Medical Dictionary for 
Regulatory Activities (MedDRA) system organ class and preferred 
term. The number of treatment-emergent adverse events (TEAEs) 
will be tabulated by auto-injector device, as well as treatment-
emergent AESIs (including in particular local injection site reactions 
LISR), treatment-emergent SAEs, TEAEs leading to permanent 
treatment discontinuation. 
For vital signs and laboratory parameters, the number of patients 
with abnormalities and/or potentially clinically significant 
abnormalities (PCSAs) will be summarized by auto-injector device. 
DURATION OF STUDY PERIOD (per 
patient)  
Total study duration (per patient) is expected to be up to 18 weeks: 
• 
Up to 2 weeks of screening period 
• 
16 weeks of study treatment period (auto-injector device 
assessment phase).

a Day is expressed in reference to the 1st administration of alirocumab (D1). 
b Visits 3, 4, 5, 6, 7, 9, 10 and 11: PK sample to be collected, these visits can be either done on site or be home-visits. 
c The self-administration on Day 1 only will be done under supervision (guidance provided) on site. Self-administrations on Week 4 (Day 29) and Week 8 (Day 57) will be done at home or on site, unsupervised and 
without any guidance. The self-administration on Week 12 (Day 85) will be done at the site and will be observed (no guidance provided, considered unsupervised). Injection site will be documented. 
d Patients will first receive paper- based training with each device by the site. They will then practice one injection with each device (SYDNEY and AI) into a training pad.

e Self-injection at the site on Days 1 (supervised) and 85 (observed, considered unsupervised). Device collected immediately after dosing. 
f 
Self-injection at home or on-site: If self –injection is performed at home, a visiting Nurse will bring supplies for blood draw, diary, and dispensed IMP kit to subject’s home and collect IMP materials post injection.  
The Visiting Nurse will not observe or provide guidance and therefore the injection will be unsupervised. After the completion of the visit the Visiting Nurse will collect all study supplies and return them to the site. 
g Treatment compliance at Week 12 applies for injection done at Week 8 and injection done at Week 12. 
h Patient perspective questionnaire: Completed by the patient after the last injection to record patient experience and satisfaction associated with use of SYDNEY to administer the 300 mg dose. 
i 
Injection-Treatment Acceptance Questionnaire (I-TAQ©): Completed by the patient after the last injection, to measure their acceptance of self-injection treatment. 
j 
Injection Experience questionnaire: Completed by the patient after each self-injection (AI or SYDNEY) addressing specific aspects of using the device. 
k Blood pressure after 5 minutes in seating resting position.  
l 
Total bilirubin (and, in case of values above the normal range, differentiation in conjugated and non-conjugated bilirubin). 
m Hematology includes: red blood cell count, hematocrit, hemoglobin, white blood cell count with differential count (neutrophils, eosinophils, basophils, monocytes, and lymphocytes), and platelets. Biochemistry 
includes: sodium, potassium, chloride, plasma glucose, calcium, urea nitrogen, creatinine, total proteins, albumin, γGT. 
n When alirocumab is to be administered, PK samples will be takien prior to alirocumab injection (Includes  assay of total and free PCSK9).

INTRODUCTION AND RATIONALE 
4.1 
INTRODUCTION 
Alirocumab is a fully human monoclonal antibody (mAb) that binds with high affinity to 
proprotein convertase subtilisin kexin type 9 (PCSK9) across several species.  PCSK9 binds to 
low-density lipoprotein receptors (LDLRs) and promotes the internalization and removal of 
LDLR on hepatocytes.  By blocking PCSK9 from binding to LDLR, alirocumab increases the 
number of LDLR available to remove low-density lipoprotein cholesterol (LDL-C) from 
circulation. Hence, alirocumab is an effective treatment to lower LDL-C and may reduce the risk 
for cardiovascular disease (CVD).  
Alirocumab (also referred to as SAR236553 and REGN727) has been developed for the treatment 
of primary hypercholesterolemia or mixed dyslipidemia and is currently being developed for the 
reduction of cardiovascular (CV) events. Alirocumab is approved in many countries, in particular 
in the United States (US) and the European Union (EU).  
More detailed information is provided in the latest version of Investigator’s Brochure.

RATIONALE 
4.2.1 Study Rationale 
The 300 mg every 4 weeks (Q4W) dosing regimen administered as 2 injections of 150 mg has 
been established as an effective, safe dosing regimen for alirocumab. In order to support the 
300 mg Q4W dosing regimen, a new auto-injector device (which is referred to as SYDNEY) with 
a volume of 2 mL has been developed. 
This larger volume device will allow delivering the 300 mg monthly dosing as a single injection 
of 2 mL of the 150 mg/mL alirocumab solution, rather than 2 separate injections of 1 mL of the 
150 mg/mL alirocumab solution with the currently marketed device. In this study, usability and 
acceptability of the large volume 2 mL SYDNEY device will be assessed when used by patients 
in an unsupervised setting. The current 1 mL auto-injector device (which is referred to as AI,) will 
be used as a calibrator for pharmacokinetics (PK), efficacy and safety.  
In order to assess usability and acceptability of this new 2 mL SYDNEY device, any PTC with 
respect to the use of SYDNEY reported by the patients will be collected. In this study, a PTC is 
defined as any complaint reported on the Patient Complaint form  that triggered an investigation 
by the Device Department and was categorized as either device-related, patient- related, or 
undetermined, whether or not associated with an AE.  
PTCs will also be collected for AI. To allow a proper assessment, only self-administration will be 
allowed and therefore patients will be instructed to self-inject in the abdomen or thigh.

4.2.2 Study description and design rationale  
The objective of this study is to assess the usability of SYDNEY in high or very high 
cardiovascular risk patients with hypercholesterolemia not adequately controlled with their 
lipid-modifying therapy (LMT).  
Study population should include  patients with either heterozygous familial hypercholesterolemia 
(heFH) or non-FH patients at high or very high cardiovascular risk (including patients with 
coronary heart disease [CHD], non-CHD CVD, and other risk factors) , not adequately controlled 
with a stable daily dose of atorvastatin (20 mg or 40 mg), or rosuvastatin (10 mg or 20 mg)  for at 
least 4 weeks prior to the screening visit, with or without LMT. 
This is a randomized, open-label, 16-week study, after a screening period of up to 2 weeks: 
Treatment periods include: 
• A parallel-arms period with one of the 2  devices (SYDNEY or AI) for the first 4 weeks. 
Patients will be randomized to receive alirocumab 300 mg Q4W, self-administered using 
either SYDNEY or AI  on Week 0 (Day 1) for the first injection, that will be done on site, 
under supervision and guidance of the Investigator or designee.  
• A single-arm period (with SYDNEY only) for the subsequent weeks until Week 16 
All patients will receive alirocumab 300 mg Q4W, self-administered using only 
SYDNEY, for the 2nd, 3rd and 4th injections on Week 4, Week 8 and Week 12 respectively.  
The Week 4 and Week 8 injections will be performed at home or on-site without 
supervision or guidance. The Week 12 injection will be performed at the site and will be 
under observation only; there will be no guidance provided. Therefore the Week 12 
injection is also considered to be unsupervised. 
Patients assigned to the AI will switch to SYDNEY after the first self-injection to allow for the 
maximum use of SYDNEY in this study (ie, a total of 180 unsupervised injections to be 
performed with the new device), for the evaluation of safety, efficacy and ease of use of the 2 mL 
device in all the study participants. 
The proposed design would support bridging the data for the alirocumab 300 mg monthly dosing 
regimen obtained with the currently marketed 1 mL AI to the new 2 mL SYDNEY. 
It also allows for a descriptive comparison of the two devices up to Week 4 only (after the first 
dose) for pharmacokinetic/pharmacodynamic (PK/PD) and safety (including local injection site 
reactions [LISR]).

STUDY DESIGN 
6.1 
DESCRIPTION OF THE STUDY 
This is a multicenter, randomized, open-label, 16-week study conducted in the US, with 2 parallel 
arms (parallel-arm period) for the first 4 weeks, and then only one arm (single-arm period) for the 
subsequent weeks until Week 16.   
After a screening period of up to 2 weeks, all patients will be trained in self-injection using both 
devices at clinical site on Week 0 (Day 1) before randomization. They will first receive 
paper-based training with each device by the site. They will then practice one injection with each 
device (SYDNEY and AI) into a training pad.  
Randomization will occur when training is completed and considered satisfactory by the site.  
Eligible patients will then be randomly allocated to receive alirocumab 300 mg Q4W, 
self-administered using either SYDNEY or AI for the first injection on Week 0 (Day 1). This 
injection will be performed at the site under supervision and guidance.  
Subsequently, from Week 4 (Day 29), all patients will receive alirocumab 300 mg Q4W 
self-administered using only SYDNEY for the 2nd, 3rd and 4th injections on Week 4 (Day 29), 
Week 8 (Day 57) and Week 12 (Day 85) respectively.  
The Week 4 and Week 8 injections may be performed at home or on site without supervision or 
guidance. The Week 12 injection will be performed at the site and will be under observation only; 
there will be no guidance provided by  the investigator or designee, and is therefore also  
considered unsupervised. This observation will assess whether the self-injection is performed 
adequately with this information recorded in the e-CRF.  
On Week 0 (Day1), Week  1 (Day 8), Week 2 (Day 15), Week 3 (Day 22), Week 4 (Day 29), 
Week 8 (Day 57), Week 12 (Day 85), Week 13 (Day 92), Week 14 (Day 99), and Week 15 
(Day 106), Week 16 (Day 113), PK collection, AE reporting, and concomitant medication 
reporting will be required. At the above mentioned time points, the patient has a choice to 
complete the assessment at the study site or in the patient’s home (home visit).  Should a patient 
prefer that sample collection be done at home instead of at the site, a research nurse will visit the 
patient’s home to complete the required PK blood draw and management prior to the sample 
being shipped to the central lab. The Visiting Nurse will also bring the IMP and supplies 
(including diary) for the patient to administer unsupervised (the nurse will not provide any 
guidance or be in the room while the dose is self administered).  After the completion of the visit 
the Visiting Nurse will collect all study supplies and return them to the site. 
The Week 12 visit will be the end-of-treatment (EOT) visit. The Week 16 visit will be the 
end-of-study (EOS) visit.

A possible complaint identified by the investigator following the patient diary review and the 
patient interview, will trigger the completion of the Patient Complaint form by the investigator.  
The completed Patient Complaint form and the corresponding device (both elements referred as 
“complaint sample”) will be sent to the Research & Development (R&D) complaint office, where 
the type of complaint will be determined: whether the complaint is packaging related or 
potentially due to device issue or patient use. All complaint samples which are potentially due to 
device issue or patient use will be sent to Site Frankfurt Devices (SFD)/PTC Center where, after 
an investigation, the complaint will be classified  as device-related, or  patient- related, or 
undetermined (in case it cannot be determined whether the PTC is device or patient related), or 
not related to device nor patient (see Appendix B).  
6.2 
DURATION OF STUDY PARTICIPATION 
6.2.1 Duration of study participation for each patient 
The total study duration (per patient) is expected to be up to 18 weeks: 
• Up to 2 weeks of screening period. 
• 16 weeks of study treatment period (auto-injector device assessment phase). 
6.2.2 Determination of end of clinical trial (all patients)

STUDY TREATMENTS 
8.1 
INVESTIGATIONAL MEDICINAL PRODUCT(S) 
Sterile alirocumab drug product will be supplied at a concentration of 150 mg/mL in an aqueous 
buffer, pH 6.0, containing sucrose, histidine, and polysorbate 20 as 1 mL or 2 mL volume 
respectively in a current auto-injector or in a new auto-injector. 
8.1.1 Description of the auto-injectors  
In this study protocol, AI refers to the current commercial 1 mL device only, SYDNEY refers to 
the new 2 mL device. 
8.1.1.1 Current auto-injector: AI 
The currently marketed device,  1 mL AI, delivers 2 separate 1 mL injections of the 150 mg/mL 
Praluent® (alirocumab) for the 300 mg Q4W dosing regimen.

8.1.1.2 New auto-injector: SYDNEY 
The new 2 mL AI,  SYDNEY, is a two-step disposable auto-injector designed to deliver 2 mL of 
150 mg/ mL Praluent® (alirocumab) subcutaneously in ≤20 seconds. 
The main features of SYDNEY include: 
• An easy to use buttonless device for the patients  
• A needle safety cover that shields the needle at start of injection and extends to cover the 
needle when the AI is removed from the skin, which helps preventing needle stick injury 
• An inspection window to allow visibility of the medication and provide feedback before 
and after injection (window changes from transparent to purple) 
• Visible and audible cues to signal the start and end of injection 
• A single-use, disposable device 
• Self-disabling feature to prevent re-use 
• An arrow around the inspection window (indicating the direction to push the pen against 
the skin) 
The main functional difference other than the injected volume between the new and the current 
device is that there is one step less for preparation of the injection with the new device, there is no 
longer the need to push a button to start the injection. 
This new 2 mL AI, SYDNEY, is illustrated in Figure 2.

8.1.2 Route and method of administration 
An Instructions for Use sheet will be provided to patients containing detailed instructions on use.  
The IMP will be administered by self-injection. The used auto-injector will be returned to the site 
for accountability and reconciliation.  
It is recommended that the IMP injections be rotated within an anatomical area (eg, right thigh 
then left thigh or right abdomen then left abdomen).  Patients also have the option to inject in a 
different anatomical area (eg, thigh then abdomen) during the study. Patients should not inject into 
areas where the skin is bruised, tender, hard, red, or hot. 
It should be noted that if patients have problems activating the auto-injector by pressing the 
needle cover against their belly (eg, soft tissue), it is recommended to inject into the thigh, where 
the skin is firmer than the belly. If another concomitant drug is being injected at the same site 
planned for the IMP injection, then the patient should be advised to use an alternate location for 
administration of the IMP. 
Patients will be asked to store the IMP in a refrigerator. Prior to administration, the IMP should be 
set outside in a safe location at room temperature for about 45 minutes. Thereafter, the IMP 
should be administered as soon as possible. 
8.1.3 Timing of administration 
On Day 1, prior to the randomization, all patients will be trained in self-injection using both 
devices at clinical site. They will first receive paper-based training with each device by the 
investigator or designee. They will then practice one injection with each device (current and new 
auto-injector devices) into a training pad. 
Randomization will occur when training is completed and considered satisfactory by the 
investigator or designee.  
Patients will be randomized to receive self-administered alirocumab 300 mg Q4W subcutaneously 
via either SYDNEY or AI for the first injection on Week 0 (Day 1).  
The treatment period will start as soon as possible after the call for randomization using the 
treatment kit number provided by the Interactive Response Technology (IRT). The first injection 
after randomization will be done at the investigational site by the patient under direct site staff 
supervision.  Patients will be monitored at the investigational site for at least 30 minutes after this 
first injection.

Subsequently, all patients will receive self-administered alirocumab 300 mg Q4W via SYDNEY 
for the 2nd, 3rd and 4th injections on Week 4 (Day 29), Week 8 (Day 57) and Week 12 (Day 85).   
• The 2nd and 3rd injections will be done unsupervised at home or on site. 
• The 4th injection will be done on site under observation by a caregiver (considered 
unsupervised), as no direction or prompting will be given. This observation will assess 
whether the self-injection is performed adequately with this information recorded in the e-
CRF. 
IMP should ideally be administered subcutaneously at approximately the same time of the day 
Q4W; however it is acceptable to have a window period of ± 3 days. The time of the day is based 
on patient’s preference.  
8.2 
NONINVESTIGATIONAL MEDICINAL PRODUCT(S) 
The following classes of drugs are identified as noninvestigational medicinal products (NIMP) 
because the medication is a potential background therapy: 
• Atorvastatin 20 mg or 40 mg, rosuvastatin 10 mg or 20 mg. 
• Cholesterol absorption inhibitors (ezetimibe), 
• Bile acid-binding sequestrants (such as cholestyramine, colestipol, colesevelam), 
• Nicotinic acid, 
• Fenofibrate, 
• Omega-3 fatty acids (≥1000 mg daily). 
8.3 
BLINDING PROCEDURES 
Not applicable, this study is an open-label design. 
8.4 
METHOD OF ASSIGNING PATIENTS TO TREATMENT GROUP 
The randomized treatment kit number list is generated centrally by Sanofi. The IMPs are 
packaged in accordance with this list. 
The trial Supply Operation Manager will provide the randomized list of treatment kit numbers and 
the Study Biostatistician will provide the randomization scheme to the centralized treatment 
allocation system provider. Then, this centralized treatment allocation system provider will 
generate the patient randomization list according to which it will allocate the treatment kits to the 
patients. 
Patients will be randomized to receive either SYDNEY or AI for the first injection at Week 0 (on 
Day 1) using a ratio 1:1.

Page 35 
The treatment kit numbers will be allocated using the centralized treatment allocation system 
(IRT) on randomization visit Week 0 (Day 1), Week 4 (Day 29), Week  8 (Day 57) and Week 12 
(Day 85). 
Before randomizing a patient, the Investigator or designee will have to contact the centralized 
treatment allocation system (IRT). 
A randomized patient is defined as a patient who is registered and assigned with a treatment kit 
number from the centralized treatment allocation system, as documented from its log file. A 
patient cannot be randomized more than once in the study. If a treatment is used without 
contacting the centralized treatment allocation system (IRT), the patient will be considered as not 
randomized and withdrawn from the study. 
8.5 
PACKAGING AND LABELING 
The treatment kit with AI will be prepared to contain 2 auto-injectors (2 x 1 mL) whereas the 
treatment kit with SYDNEY will be prepared to contain 1 auto-injector (1 x 2 mL).  
In addition to the open-label treatment kits, a dummy kit for practice containing 1 auto-injector 
each will be prepared for the purpose of instructing patients on injection administration which is 
to be performed prior to randomization. These training injections will be performed on site at 
randomization Week 0 (Visit 2, Day1). 
Packaging is in accordance with the administration schedule. The content of the labeling is in 
accordance with the local regulatory specifications and requirements.

STORAGE CONDITIONS AND SHELF LIFE 
At the investigational site, stored IMP should be kept in an appropriate locked room, under the 
responsibility of the investigator or designee or other authorized person in accordance with local 
regulations, labeling specifications, policies and procedures. Control of IMP storage conditions, 
especially control of temperature (eg, refrigerated storage between +2°C and +8°C [36°- 46° F] at 
the site) and information on in-use stability and instructions for handling the alirocumab should be 
managed according to the rules provided by the Sponsor (eg, the temperature of the site 
refrigerator should be checked daily and recorded on a log sheet). 
IMP will be either given to the patient for self-administration while on site or the supplies will be 
brought and collected by the Visiting Nurse in an appropriate transport bag at the refrigerated 
temperature.   
The IMP must be administered in accordance with the Instructions for Use. If the storage and in 
use conditions described in the Instructions for Use are not followed, do not administer the IMP.

RESPONSIBILITIES 
The Investigator, the hospital pharmacist, or other personnel allowed to store and dispense the 
IMP will be responsible for ensuring that the IMP used in the clinical trial is securely maintained 
as specified by the Sponsor and in accordance with applicable regulatory requirements. 
All IMP will be dispensed in accordance with the Clinical Trial Protocol and it is the 
Investigator's responsibility to ensure that an accurate record of IMP issued and returned is 
maintained. 
Any quality issue noticed with the receipt or use of an IMP (deficiency in condition, appearance, 
pertaining documentation, labeling, expiration date, etc) should be promptly notified to the 
Sponsor. Some deficiencies may be recorded through a complaint procedure (see Section 6.1) . 
A potential defect in the quality of IMP may be subject to initiation of a recall procedure by the 
Sponsor. In this case, the Investigator will be responsible for promptly addressing any request 
made by the Sponsor, in order to recall the IMP and eliminate potential hazards. 
Under no circumstances will the Investigator supply IMP to a third party (except for the Visiting 
Nurse who has been approved by the Sponsor), allow the IMP to be used other than as directed by 
this clinical trial protocol, or dispose of IMP in any other manner. 
8.7.1 Treatment accountability and compliance 
IMP administration data will be recorded by the Investigator or designee on the e-CRF. 
Measures taken to ensure and document IMP compliance and accountability are described below: 
• The Investigator or designee will obtain via IRT the treatment kit number(s) and he/she 
will dispense the treatment kit(s) to the patient. 
• The Investigator or designee will enter the treatment kit packaging number(s) and the kit 
numbers in the e-CRF, if applicable. 
• The accountability is to be performed at IMP kit re-supply visits only. The used and 
unused kit(s) should be brought back to such visits for accountability purposes. 
• The monitor will check the data consistency between e-CRF pages, treatment log forms 
using patient’s diary, and returned unused IMPs of a corresponding kit. 
The patient will be instructed on the importance to take the study treatment as planned for the 
remainder of the treatment duration, as well as the need to return all used and unused IMP kits at 
each site visit.

8.7.2 Return and/or destruction of treatments 
All treatments kits will be retrieved from the site by the Sponsor. A detailed treatment log of the 
returned IMP will be established with the Investigator (or the pharmacist) and countersigned by 
the Investigator and the monitoring team.  
8.8 
CONCOMITANT MEDICATION 
A concomitant medication is any treatment received by the patient concomitantly to any IMP(s) 
during the study. This medication is not provided by the Sponsor. 
Concomitant medications should be kept to a minimum during the study. However, if these are 
considered necessary for the patient’s welfare and are unlikely to interfere with the IMP, they may 
be given at the discretion of the Investigator, with a stable dose (when possible). Besides the 
specific information related to concomitant medications provided in this section, any other 
concomitant medication(s) will be allowed and will have to be recorded in the e-CRF and source 
data. 
8.8.1 Management of background lipid-modifying therapy 
For background LMT, including statins (atorvastatin 20 and 40 mg, rosuvastatin 10 and 20 mg), 
sites must follow the national product label for the safety monitoring and management of patients. 
Patients will be on stable dose of statin therapy with or without other LMT during the study as 
indicated in Section 7. 
From the screening visit until the Week 16 visit, the background LMT should not be changed. No 
dose adjustment, discontinuation or initiation of other statins or other LMT should take place 
during this time, barring exceptional circumstances whereby overriding concerns warrant such 
changes, as per the Investigator’s judgment.  
Should the patient require the introduction of a fibrate during the course of the study (ie, as rescue 
treatment) only fenofibrate will be allowed to be added. 
8.8.2 Contraception 
Women of childbearing potential must use an effective contraceptive method throughout the 
entire duration of the study treatment. It is also recommended to continue using an effective 
contraceptive method for at least 4 weeks after the last injection of IMP. The applied methods of 
contraception have to meet the criteria for a highly effective method of birth control according to 
the “International Conference on Harmonization of Technical Requirements for Registration of 
Pharmaceuticals for Human Use. M3(R2): Guidance on nonclinical safety studies for the conduct 
of human clinical trials and marketing authorization for pharmaceuticals. ICH. 2009 Jun: 1-25”

8.8.3 Prohibited concomitant medications 
The following therapies are not allowed during the study (including the screening period until the 
EOS visit): 
• Red yeast rice products 
• Fibrates, other than fenofibrate 
• Other PCSK9 inhibitors 
Note: while red yeast rice is considered a dietary supplement/nutraceutical, it contains HMG CoA 
reductase inhibitor activity (mechanism of action of statins), along with other active ingredients. 
Because such products lack standardization, varying amounts of the active substance could lead to 
alterations in lipids during the study and potentially confound the LDL-C assessment. 
8.9 
LIFESTYLE AND DIETARY HABITS 
Lifestyle and dietary habits should be maintained if possible throughout the entire study duration, 
as medically feasible, with minimum changes. There shall be no significant changes in nutritional 
composition of the diet or in the quantity/pattern of food consumed.

ASSESSMENT OF INVESTIGATIONAL MEDICINAL PRODUCT 
9.1 
PRIMARY ENDPOINT 
The primary endpoint is the number (%) and types of SYDNEY-associated product technical 
complaints (PTCs)* at the unsupervised injections on Weeks 4, 8, and 12. 
* Product technical complaints (PTC)  
In this study, all complaints that triggered an investigation by the Device Department will be 
categorized as device-related, patient- related, undetermined, or not related to device nor patient, 
whether or not associated with an AE. In this study, a PTC is defined as any complaint reported 
on the Patient Complaint form that triggered an investigation by the Device Department and was 
categorized as either device-related,  patient- related or undetermined. The complaints categorized 
as not related to device nor patient will not be considered as a PTC. This definition will be used 
for both primary and secondary endpoints. 
Patient diaries 
Patients will be given diaries to complete after each self-injection they perform using the 
auto-injector device. The diary will include specific questions about the self-injection process. 
At each visit, the Investigator will review the diary with the patient, and confirm more particularly 
whether there were any problems associated with the auto-injector during study treatment 
administration and record the experience in the e-CRF. 
Following interview with the patient, in the event the Patient complaints form is completed by the 
investigator, this form and the corresponding auto-injector device (both elements referred as 
“complaint sample”) will be sent to the Sponsor for identification of as described in Section 6.1. 
In case a PTC is associated with the occurrence of an AE, the AE must be documented on an AE 
page in the e-CRF. In case a PTC is associated with the occurrence of a SAE, the SAE must be 
reported to the Monitoring Team in accordance with the SAE reporting procedures. 
9.1.1 Collection of devices 
All used auto-injector devices will be collected by the site. In case a Patient Complaints form is 
completed, the concerned device will be sent to the Sponsor along with the Patient Complaints 
form.

9.2.4 Efficacy/Pharmacodynamics assessments: 
The efficacy secondary endpoint is represented by the percent and absolute change from baseline 
in LDL-C at Weeks 4, 8, 12 and 16. 
At all visits LDL-C will be calculated using the Friedewald formula (3). For the purpose of 
calculating LDL-C through the Friedewald formula, blood sampling will be done for 
determination of  Total-cholesterol (Total-C), high-density lipoprotein cholesterol (HDL-C), and 
TG.  If TG values exceed 400 mg/dL (4.52 mmol/L) then the central lab will reflexively measure 
(via the beta quantification method) the LDL-C rather than calculating it. 
The blood sampling for lipid parameters should be performed in the morning, in fasting condition 
(at least 10 to 12 hours fast and refrain from smoking). Alcohol consumption within 48 hours and 
intense physical exercise within 24 hours preceding the blood sampling are discouraged. The 
sample handling procedure will be provided separately in a Central Lab manual. 
9.2.4.1  Pharmacodynamic parameter 
The pharmacodynamic endpoint will be the percent change in LDL-C value from baseline to 
Week 4 defined as: 100x (LDL-C value at Week 4 - LDL-C value at baseline) / LDL-C value at 
baseline. 
The baseline LDL-C value will be the last LDL-C level obtained before the first injection of IMP. 
The LDL-C at Week 4 will be the LDL-C level obtained within the Week 4 analysis window.

All calculated and measured LDL-C values (scheduled or unscheduled, fasting or not fasting) may 
be used in the analyses if appropriate according to above definition and analysis windows used to 
allocate a time point to a measurement. Analysis windows will be defined in the statistical 
analysis plan (SAP). In case both calculated and measured LDL-C are provided for the same 
sampling, the measured LDL-C will be considered. 
Percent and absolute change from baseline in LDL-C will also be calculated at Week 8, 12 and 
16. They will be summarized descriptively. 
9.2.5 Safety assessments 
Adverse events, spontaneously reported by the subject or observed by the Investigator, will be 
monitored at each visit. This includes SAEs, detailed in Section 10.4.1.2, AEs of special interest 
(AESIs) detailed in Section 10.4.1.3, laboratory data, vital signs assessed throughout the study. 
Specific additional forms will be completed for AESI. For any Local Injection Site Reactions 
(LISR), and general allergic AEs, whether or not reported as AESI, special forms on symptoms 
will have to be completed (see Section 10.6). 
Assessment of safety will be based on clinical safety endpoints, laboratory safety variables, vital 
signs, and physical examination.  
9.2.5.1 Adverse events 
Refer to Section 10.4 up to Section 10.7 for details. 
9.2.5.2 Laboratory safety variables 
The clinical laboratory data consist of blood analysis including the following:  
• Hematology: red blood cell count, hematocrit, hemoglobin, white blood cell count with 
differential count (neutrophils, eosinophils, basophils, monocytes, and lymphocytes), 
platelets. 
• Biochemistry: sodium, potassium, chloride, calcium, plasma glucose, urea nitrogen, 
creatinine, albumin, total proteins, gamma-glutamyl transferase (γGT). 
• Liver function panel: aspartate aminotransferase (AST), Alanine aminotransferase (ALT), 
alkaline phosphatase (ALP), and total bilirubin (and, in case of values above the normal 
range, differentiation in conjugated and non-conjugated bilirubin). 
• Creatine phosphokinase (CPK).  
• Urine and serum (beta-human chorionic gonadotropin [β-HCG])   pregnancy test for 
women of child bearing potential (WOCBP) only. 
Clinical laboratory values will be analyzed after conversion into standard international units.

APPROPRIATENESS OF MEASUREMENTS  
The primary endpoint is the number (%) and types of PTCs associated with the use of SYDNEY 
during the 3 unsupervised injections at Week 4, Week 8 and Week 12. This will allow to assess 
the robustness, usability and acceptability of the new 2 mL SYDNEY device. With an estimation 
of 60 evaluable patients using SYDNEY (30 patients in the SYDNEY group since Day 1 and 
30 additional patients from the AI group switching to SYDNEY group after the 1st injection), a  
total of 180 unsupervised injections with SYDNEY will be assessed. 
The data collected will also allow for evaluation of PK, safety, efficacy and use in real world 
setting of the 2 mL SYDNEY device in all study participants, from Week 4 injection. 
Up to Week 4, the parallel arm design will allow for PK, PD and safety (including LISR) to be 
compared between SYDNEY and AI.

10.3 
HANDLING OF PATIENT TEMPORARY OR PERMANENT TREATMENT 
DISCONTINUATION AND OF PATIENT STUDY DISCONTINUATION  
The IMP should be continued whenever possible. In case the IMP is stopped, it should be 
determined whether the stop can be made temporarily; permanent IMP discontinuation should be 
a last resort. Any IMP discontinuation should be fully documented in the e-CRF. In any case, the 
patient should remain in the study as long as possible. 
• Pregnancy will lead to definitive treatment discontinuation in all cases. 
10.3.1 Temporary treatment discontinuation with investigational medicinal product(s) 
Temporary treatment discontinuation may be considered by the Investigator because of suspected 
AEs. Reinitiation of treatment with the IMP will be done under close and appropriate clinical/and 
or laboratory monitoring once the Investigator will have considered according to his/her best 
medical judgment that the responsibility of the IMP(s) in the occurrence of the concerned event 
was unlikely and if the selection criteria for the study are still met (refer to Section 10.3.3 and  
Section 10.3.4). 
For all temporary treatment discontinuations, duration should be recorded by the Investigator in 
the appropriate pages of the e-CRF.  
Temporary treatment discontinuation is defined as one or more scheduled injections that are not 
administered to the patient as decided by the Investigator

Page 56 
10.3.2 Permanent treatment discontinuation with investigational medicinal product(s) 
Permanent treatment discontinuation is any treatment discontinuation associated with the 
definitive decision from the Investigator or the patient not to re-expose the patient to the IMP at 
any time. 
Patient withdrawal from the study treatment or study should be avoided as much as possible. 
10.3.3 List of criteria for permanent treatment discontinuation 
The patients may withdraw from treatment with the IMP if they decide to do so, at any time and 
irrespective of the reason, or this may be the Investigator’s decision. All efforts should be made to 
document the reasons for treatment discontinuation and this should be documented in the e-CRF.  
Patients should discontinue IMP for the following reasons: 
• Pregnancy, intention for pregnancy, or no longer using effective contraceptive method of 
birth control (females only). 
• Acute injection reaction of clinical concern. 
• Serious or severe hypersensitivity reaction considered related to IMP. 
• At patient request, ie, withdrawal of consent for treatment. 
• If, in the Investigator's opinion, continuation with the administration of the IMP would be 
detrimental to the patient's well-being. 
• Intercurrent condition that requires discontinuation of the IMP. 
• At the specific request of the Sponsor. 
Any abnormal laboratory value will be immediately rechecked for confirmation (after 24 hours) 
before making a decision of permanent discontinuation of the IMP for the concerned patient. 
10.3.4 Handling of patients after permanent treatment discontinuation 
Patients will be followed-up according to the study procedures specified in this protocol up to the 
scheduled date of study completion, or up to recovery or stabilization of any AE to be followed-
up as specified in this protocol, whichever comes last. 
If possible, and after the permanent discontinuation of treatment, the patients will be assessed 
using the procedures normally planned for the last dosing day with the IMP (this EOT visit should 
take place within 5 days of treatment discontinuation, if possible) including a PK sample, if 
appropriate.  
The patient, at a minimum, should then be followed-up for 4 weeks from the last administration of 
IMP or until recovery or stabilization of any AE as specified in this protocol, whichever comes 
last. A final end of study visit will take place 4 weeks after the premature discontinuation.

Page 57 
All cases of permanent treatment discontinuation should be recorded by the Investigator in the 
appropriate pages of the e-CRF when considered as confirmed. IRT should be notified when a 
patient prematurely discontinues study treatment. In the medical record, at least the date of the 
withdrawal and the reason should be documented. 
10.3.5 Procedure and consequence for patient withdrawal from study 
The patients may withdraw from the study before study completion if they decide to do so, at any 
time and irrespective of the reason without any effect on their care. However, if patients no longer 
wish to take the IMP, they will be encouraged to remain in the study. If possible, the patients are 
assessed using the procedure normally planned for the EOS visit including a PK sample. 
The Investigators should discuss with them key visits to attend. The value of all their study data 
collected during their continued involvement will be emphasized as important to the public health 
value of the study. 
Patients who withdraw should be explicitly asked about the contribution of possible AEs to their 
decision to withdraw consent, and any AE information elicited should be documented.  
All study withdrawals should be recorded by the Investigator in the appropriate screens of the 
e-CRF and in the patient’s medical records when considered as confirmed. In the medical record, 
at least the date of the withdrawal and the reason should be documented. 
For patients who fail to return to the site, unless the patient withdraws consent for follow-up, the 
Investigator should make the best effort to recontact the patient (eg, contact patient’s family or 
private physician, review available registries or health care databases), and to determine his/her 
health status, including at least his/her vital status. Attempts to contact such patients must be 
documented in the patient’s records (eg, times and dates of attempted telephone contact, receipt 
for sending a registered letter). 
Patients who have withdrawn from the study cannot be rerandomized in the study. Their inclusion 
and treatment numbers must not be reused.

OBLIGATION OF THE INVESTIGATOR REGARDING SAFETY REPORTING 
10.4.1 Definitions of adverse events  
10.4.1.1 Adverse event 
An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation 
patient administered a pharmaceutical product and which does not necessarily have to have a 
causal relationship with this treatment.

10.4.1.2 Serious adverse event 
A serious adverse event (SAE) is any untoward medical occurrence that at any dose: 
• Results in death, or 
• Is life-threatening, or 
Note: The term “life-threatening” in the definition of “serious” refers to an event in which 
the patient was at risk of death at the time of the event; it does not refer to an event which 
hypothetically might have caused death if it were more severe. 
• Requires inpatient hospitalization or prolongation of existing hospitalization, or 
• Results in persistent or significant disability/incapacity, or 
• Is a congenital anomaly/birth defect 
• Is a medically important event 
Medical and scientific judgment should be exercised in deciding whether expedited 
reporting is appropriate in other situations, such as important medical events that may not 
be immediately life-threatening or result in death or hospitalization but may jeopardize the 
patient or may require medical or surgical intervention (ie, specific measures or corrective 
treatment) to prevent one of the other outcomes listed in the definition above. 
Note: The following list of medically important events is intended to serve as a guideline 
for determining which condition has to be considered a medically important event. The list 
is not intended to be exhaustive: 
- 
Intensive treatment in an emergency room or at home for: 
• 
Allergic bronchospasm  
• 
Blood dyscrasias (ie, agranulocytosis, aplastic anemia, bone marrow aplasia, 
myelodysplasia, pancytopenia, etc),  
• 
Convulsions (seizures, epilepsy, epileptic fit, absence, etc). 
- 
Development of drug dependence or drug abuse 
- 
Suicide attempt or any event suggestive of suicidality 
- 
Syncope, loss of consciousness (except if documented as a consequence of blood 
sampling) 
- 
Bullous cutaneous eruptions 
- 
Required Intervention to Prevent Permanent Impairment or Damage (Devices):  
If you believe that the intervention was necessary to preclude permanent impairment of 
a body function, or prevent permanent damage to a body structure, either situation 
suspected to be due to the use of a medical product.

10.4.1.3 Adverse event of special interest 
An adverse event of special interest (AESI) is an AE (serious or nonserious) of scientific and 
medical concern specific to the Sponsor’s product or program, for which ongoing monitoring and 
immediate notification by the Investigator to the Sponsor is required. Such events may require 
further investigation in order to characterize and understand them. Adverse events of special 
interest may be added, modified or removed during a study by protocol amendment. 
Adverse Events of Special Interest (AESI) are AEs (serious or non-serious) that need to be 
monitored, documented, and managed in a pre-specified manner described in the protocol.  
For these AEs, the Sponsor will be informed immediately (ie within 24 hours), as per SAEs 
notification described in Section 10.4.1.2 even if not fulfilling a seriousness criterion, using the 
corresponding screens in the e-CRF. 
The following AEs are considered as AESIs in the study: 
• Pregnancy occurring in a female patient entered in the clinical trial or in a female partner 
of a male patient entered in the clinical trial.  
- 
It will be qualified as an SAE only if it fulfills one of the seriousness criteria (see 
Section 10.4.1.2). 
- 
In the event of pregnancy in a female participant, IMP should be discontinued.  
- 
Follow-up of the pregnancy in a female participant or in a female partner of a male 
participant is mandatory until the outcome has been determined. 
• Symptomatic overdose (serious or nonserious) with IMP/NIMP 
- 
An overdose (accidental or intentional) with the IMP/NIMP is an event suspected by 
the Investigator or spontaneously notified by the patient (not based on systematic pills 
count) and defined as at least twice the intended dose within the intended therapeutic 
interval 
- 
Of note, asymptomatic overdose has to be reported as a standard AE. 
- 
The circumstances (ie, accidental or intentional) should be clearly specified in the 
verbatim and symptoms, if any, entered on separate AE forms.  
• Increase in alanine transaminase (ALT): ALT ≥3 x ULN (if baseline ALT <ULN) or 
ALT ≥2 times the baseline value (if baseline ALT ≥ULN) (see the “Increase in ALT” flow 
diagram in Appendix E. 
• General allergic events: 
- 
Any general allergic events regardless of the cause that require consultation with 
another physician for further evaluation of hypersensitivity/allergy as per the 
Investigator’s medical judgment should be reported as an AESI.  
- 
All general allergic events require completion of the specific e-CRF screen.

• Local injection site reactions:   
- 
 Local injection site reactions that require consultation with another physician for 
further evaluation of hypersensitivity/allergy as per the Investigator’s medical 
judgment should be reported as an AESI.  
All LISR require completion of the specific e-CRF screen. 
Note:  
- 
Other LISR are non-AESIs. Please see Section 10.6 for details. 
- 
The safety instructions on allergic events and LISR are detailed in Section 10.6. 
• Neurologic events: neurologic events that require additional examinations/procedures 
and/or referral to a specialist should be reported as an AESI. If the event does not require 
additional examinations/procedures and/or referral to a specialist, it should be reported as 
a standard AE. 
• Neurocognitive events:  All neurocognitive events will be considered as AESI. 
10.4.2 General guidelines for reporting adverse events 
• All AEs, regardless of seriousness or relationship to IMP/NIMP, spanning from the 
signature of the informed consent form until the end of the study as defined by the 
protocol for that patient, are to be recorded on the corresponding page(s) or screen(s) of 
the e-CRF. 
• Whenever possible, diagnosis or single syndrome should be reported instead of symptoms. 
The Investigator should specify the date of onset, intensity, action taken with respect to 
IMP, corrective treatment/therapy given, additional investigations performed, outcome, 
and his/her opinion as to whether there is a reasonable possibility that the AE was caused 
by the IMP or by the study procedure(s).  
• The Investigator should take appropriate measures to follow all AEs until clinical recovery 
is complete and laboratory results have returned to normal, or until progression has been 
stabilized, or until death, in order to ensure the safety of the patients. This may imply that 
observations will continue beyond the last planned visit per protocol, and that additional 
investigations may be requested by the monitoring team up to as noticed by the Sponsor. 
Patients who experience an ongoing SAE or an AESI, at the prespecified study end-date, 
should be followed until resolution, stabilization, or death and related data will be 
collected.  
• When treatment is prematurely discontinued, the patient, at a minimum, should then be 
followed-up for 4 Weeks from the last administration of IMP or until recovery or 
stabilization of any AE as specified in this protocol, whichever comes last. A final end of 
study visit will take place 4 weeks after the premature discontinuation.

• Laboratory and vital signs abnormalities are to be recorded as AEs only if:  
- 
Symptomatic and/or  
- 
Requiring either corrective treatment or consultation, and/or  
- 
Leading to IMP discontinuation or modification of dosing, and/or  
-

- 
Defined as an AESI 
Instructions for AE reporting are summarized in Table 9. 
10.4.3 Instructions for reporting serious adverse events 
In the case of occurrence of an SAE, the Investigator or any designees must immediately: 
• ENTER (within 24 hours) the information related to the SAE in the appropriate screens of 
the e-CRF; the system will automatically send a notification to the monitoring team after 
approval of the Investigator within the e-CRF or after a standard delay. 
• SEND (preferably by fax or e-mail) a photocopy of all examinations carried out and the 
dates on which these examinations were performed, to the representative of the monitoring 
team whose name, fax number, and email address appear on the clinical trial protocol. 
Care should be taken to ensure that the patient's identity is protected and the patient's 
identifiers in the clinical trial are properly mentioned on any copy of a source document 
provided to the Sponsor. For laboratory results, include the laboratory normal ranges. 
• All further data updates should be recorded in the e-CRF as appropriate, and further 
documentation as well as additional information (for laboratory data, concomitant 
medications, patient status, etc) should be sent (by fax or e-mail) to the monitoring team 
within 24 hours of knowledge of the SAE. In addition, every effort should be made to 
further document any SAE that is fatal or life-threatening within a week (7 days) of the 
initial notification. 
• A back-up plan (using a paper CRF process) is available and should be used when the 
e-CRF system does not work. If the e-CRF system does not work, the investigator must 
report an SAE to the Sanofi representative within 24 hours, and the Sanofi representative 
must report the SAE to Global Pharmacovigilance & Epidemiology (GPE) within 
1 working day. 
Any SAE brought to the attention of the Investigator at any time after the end of the study for the 
patient and considered by him/her to be caused by the IMP with a reasonable possibility, should 
be reported to the monitoring team.

The completed Patient Complaints form and the corresponding device (both elements referred as 
“complaint sample”) will be sent to the R&D complaint office. 
The Investigator will assess whether or not the quality issue has to be reported together with an 
AE or SAE. 
10.5 
OBLIGATIONS OF THE SPONSOR 
During the course of the study, the Sponsor will report in an expedited manner: 
• All SAEs that are both unexpected and at least reasonably related to the IMP (SUSAR), to 
the regulatory authorities, Independent Ethics Committee (IECs)/Institutional Review 
Boards (IRBs) as appropriate and to the Investigators.   
• All SAEs that are expected and at least reasonably related to the IMPs to the regulatory 
authorities, according to local regulations. 
Adverse events that are considered expected will be specified by the reference safety information 
(Investigator’s brochure). 
The Sponsor will report all safety observations made during the conduct of the trial in the clinical 
study report. 
10.6 
SAFETY INSTRUCTIONS 
10.6.1 Local tolerability (local injection site reactions) 
In case the Investigator or the patient recognizes any signs of local intolerability, then this should 
be treated and followed-up as per the Investigator’s medical judgment. Specific e-CRF screens are 
to be filled in. Information on classifying the reaction is provided in Section 10.4, and on 
reporting these reactions is given in Appendix G. 
Local injection site reactions that are related to the alirocumab injection, as opposed to another 
injectable agent, should be further characterized by evaluating the related symptoms that comprise 
an injection site reaction such as but not limited to redness, pain, etc. If the patient experiences a 
local injection site reaction with no signs or symptoms except for erythema/redness, and/or 
swelling, and the diameter of the erythema/ redness, or swelling measure <2.5 cm, no AE for local 
injection site reaction needs to be reported as this is not typically considered a clinically important 
finding. However, if the patient has a reaction of swelling with a diameter <2.5 cm that interferes 
with activity, then it should be considered as a clinically relevant finding and should be reported 
as an AE with a corresponding grade of moderate or severe, in accordance with Appendix G.

10.6.2 General allergic adverse events 
Specific e-CRF screens are to be filled in to assess allergic AEs or allergic-like AE that may occur 
during the clinical studies conducted with alirocumab. Sometimes transient injection site 
reactions, irritant in nature, may occur, requiring no intervention and being of dubious 
significance. These reactions would not be considered to be allergic reactions. Adverse events that 
may constitute an allergic reaction (eg, generalized itch, nasal itch, swelling at injection site, 
flushing, hives, swelling at lips, eyes, face, tongue, hands, feet, lump in throat, difficulty to 
swallow, hoarseness, change in pitch of voice, incapacity to speak, wheezing, chest tightness, 
stridor, etc) should be considered to be reported on the General Allergic Event and/or Local 
Injection Site Reaction Complementary Form. 
Adverse events that are obviously not of allergic origin (eg, LISR related to mechanics of 
injection) should only be recorded on the Local Injection Site Reaction Complementary Form. 
However, injection site reactions that progress/expand/worsen/etc should be evaluated as 
recommended in Appendix G and General Allergic Reaction Complementary form should be 
completed. 
The IMP should be immediately interrupted (temporarily discontinued) if there is a suspicion of 
an allergic event related to IMP. See Section 10.3.1 for further information on treatment 
interruption and Section 10.3.3 for criteria for permanent treatment discontinuation. 
10.6.2.1 Allergic adverse event with cutaneous involvement 
Adverse events with cutaneous involvement which are obviously of allergic origin or injection 
site reactions which progress/expand/worsen/etc. should be evaluated by a dermatologist as soon 
as possible, and preferably within one week of the site first becoming aware of the event. 
The Investigator should evaluate the patient for possible etiologies (new medications, etc) and 
extracutaneous symptoms and signs. An unscheduled assessment for hematology, chemistry, liver 
panel, and PK should be obtained. An additional blood sample will have to be drawn for anti-
alirocumab antibody analyses (adequate instructions will be provided to the site by the Monitor). 
If it is possible, the site will take pictures of the skin lesions in order to provide the patient with 
them for the dermatologist’s visit. If the photos are obtained, then copies should be kept as source 
documents which may later be collected by the sponsor. The Investigator will provide a summary 
of the patient's case, reason for consultation, and information being requested to the consulting 
dermatologist.  
A full consultation report should be sent by the dermatologist to the Investigator. The full report 
should contain, at a minimum, the following information; a detailed description of the rash (such 
as the morphology [lesion type], shape of individual lesions, arrangement of multiple lesions [eg, 
scattered, grouped, linear], distribution, color, consistency, presence of pruritus or pain, and other 
clinical signs) and in case a skin biopsy (including histopathology and immunofluorescence) was 
done (if it was deemed necessary as per the dermatologist’s or Investigator’s medical judgment), 
the results of this investigation with, if applicable, a specific diagnosis of the AE. The Investigator 
will fax the full report and the corrected AE form if necessary, to the Monitoring Team 
Representative within 24 hours.

10.6.2.2 Acute allergic injection reactions 
Acute allergic injection reaction (which are considered under the category of general allergic 
events) is defined as any AE that occurs during or shortly after injection of the IMP (characterized 
by but not limited to hypotension, bronchoconstriction, urticaria, edema, angioedema, nausea, 
vomiting). Emergency equipment and medication for the treatment of these potential adverse 
effects (eg, antihistamines, bronchodilators, IV saline, corticosteroids, acetaminophen, and 
epinephrine) must be available for immediate use for the injections at the training, and inclusion 
visits. Patients will be observed at the investigational site for at least 30 minutes following the 
injection that takes place at the inclusion visit. Patients should be treated symptomatically if any 
AEs are observed. Patients are to remain at the site until any acute injection reaction is assessed as 
stable, per the Investigator’s discretion.  
A General Allergic Event and/or Local Injection Site Reaction Complementary Form will have to 
be completed. 
10.7 
ADVERSE EVENTS MONITORING 
All events will be managed and reported in compliance with all applicable regulations, and 
included in the final clinical study report.

STATISTICAL CONSIDERATIONS 
11.1 
DETERMINATION OF SAMPLE SIZE 
No formal sample size was calculated, the sample size is based on empirical considerations. 
Considering a drop-out rate of 10% it is planned to randomize 66 patients overall (33 in each 
group) in order to ensure 60 evaluable patients overall (30 in each group) resulting in 
180 unsupervised planned injections using SYDNEY, including the 2nd, 3rd and 4th unsupervised 
injections with SYDNEY for patients randomized in the AI group who will switch to SYDNEY 
group just before the second injection. 
 
With 60 evaluable patients using SYDNEY, a total of 180 unsupervised injections is expected to 
be achieved during the study. Expecting a maximum of 3 observed PTC over the 180 injections 
(observed PTC rate of 1.67%) with SYDNEY, the upper bound of the 2-sided 95% confidence 
interval calculated with the Wilson score method will be no higher than 5.2%.   
11.2 
 DISPOSITION OF PATIENTS 
Screened patients are defined as any patient who met the inclusion criteria and none of the 
exclusion criteria, and signed the informed consent. 
Randomized patients are all screened patients with a treatment kit number allocated and recorded 
in the IRT database, regardless of whether or not the treatment kit was used. These patients form 
the randomized population. Patients treated without being randomized will not be considered as 
randomized. 
The safety experience of patients treated and not randomized will be reported separately, and 
these patients will not be included in the safety population. 
11.3 
ANALYSIS POPULATIONS 
11.3.1 Modified intent-to-treat populations 
The primary efficacy analysis population that will be used for the analyses of LDL-C will be the 
modified intent-to-treat (mITT ) population.  
The mITT population of the parallel arms period will consist of all randomized patients who 
receive at least 1 dose or part of a dose of IMP visit during this period and who had an evaluable 
value of LDL-C at baseline and an on-treatment LDL-C value within Week 4 analysis window. 
The treatment period for the parallel arms period is defined as the time period from the first IMP 
injection up to 35 days after this injection or up to the day before the second injection, whichever 
comes first. Patients in this mITT population will be analyzed according to the auto-injector 
device group allocated by randomization (ie, as-randomized treatment group).

Page 67 
The mITT population of the single-arm period will consist of all randomized patients who 
continue in single-arm period and receive at least 1 dose or part of a dose of IMP of this period 
and who had an evaluable value of LDL-C at baseline and at least one on-treatment LDL-C within 
one of the analysis windows from Week 8 to Week 16. The treatment period for the single-arm 
period is defined as the time period from the second IMP injection up to 35 days after the last IMP 
injection for patients entering into the single arm period. 
11.3.2 Safety populations 
The safety population of the parallel arms period will consist of all randomized patients who 
receive at least 1 dose or part of a dose of IMP during this period. Patient data will be analyzed 
according to the auto-injector device actually used. 
The safety population of the single-arm period will consist of all randomized patients who 
continue in the single-arm period and receive at least 1 dose or part of a dose of IMP during this 
period. 
All safety and PTC analyses will be performed on these populations.  
In addition: 
• Nonrandomized but treated patients will not be part of the safety population, but their 
safety data will be presented separately 
• Randomized patients for whom it is unclear whether they took the IMP will be included in 
the safety population as randomized 
• For a patient receiving injections with an auto-injector device different than the 
randomized auto-injector device during the parallel-arms period, the auto-injector device 
group allocation for as-treated analysis will be the auto-injector device actually used. 
11.3.3 Pharmacokinetic populations 
The PK population of the parallel-arms period will consist of all randomized patients who receive 
at least at least 1 dose or part of a dose of IMP and had at least one evaluable blood sample for PK 
during this period. All patients will be analyzed according to the auto-injector device that they 
actually used.  
The PK population of the single-arm period will consist of all randomized patients who receive at 
least 1 dose or part of a dose of IMP and had at least one evaluable blood sample for PK during 
this period. 
These PK populations will be used for the analyses of alirocumab concentrations and PCSK9 
concentrations.

11.3.4 Anti-alirocumab antibody population 
The anti-alirocumab antibody population of the parallel-arm period will consist of all randomized 
patients who receive at least 1 dose or part of a dose of IMP during this period (safety population) 
with an available ADA sample at baseline and at least one post-baseline available ADA sample 
during this period. 
The anti-alirocumab antibody population of the single-arm period will consist of all randomized 
patients who receive at least 1 dose or part of a dose of IMP during this period (safety population) 
with an available ADA sample at baseline and at least one post-baseline available ADA sample 
during this period. 
11.4 
STATISTICAL METHODS 
Unless otherwise specified, analyses will be performed by auto-injector device group in the 
parallel-arms period and overall in the single-arm period.  
The baseline value is defined as the last available value obtained up to the date and time of the 
first IMP administration. 
11.4.1 Extent of study treatment exposure and compliance 
The extent of study treatment exposure and compliance will be assessed and summarized by 
actual auto-injector device used within the safety population for each study period. 
11.4.1.1 Extent of investigational medicinal product exposure 
No duration of IMP exposure will be calculated for the parallel-arms period since patients will 
receive only one injection during this period. The proportion of patients having received the first 
injection will be summarized. 
The duration of IMP exposure for the single-arm period is defined as: last IMP injection 
date - first IMP injection date during this period + 28 days (regardless of unplanned intermittent 
discontinuations). The number of injections received during the single-arm period will also be 
summarized.   
11.4.1.2 Compliance  
No treatment compliance to the IMP will be calculated for the parallel-arms period since patients 
will receive only one injection during this period. 
Treatment compliance to the IMP for the single-arm period will be assessed using the mean 
injection frequency, defined for each patient, as the average number of days between 2 
consecutive injections, that is: (last injection date – first injection date during this period)/(number 
of injections -1) for patients receiving at least 2 injections during this period.

11.4.2 Analyses of primary endpoint 
The primary endpoint (ie, number (%) and types of SYDNEY-associated PTCs related to the 
unsupervised injections [Section 9.1]) will be described on the safety population for the single 
arm period. The number and % of PTCs will be provided with the 95% CI using Wilson score 
method. If applicable, the number of PTCs per patient will be described. In addition the type of 
PTCs will be described. 
11.4.3 Analyses of secondary efficacy endpoints 
All secondary device-related endpoints (Section 9.2.1) will be analyzed on the safety population 
using descriptive statistics. In addition, 95% CI for the number of PTCs, number and % of 
patients with any PTCs will be provided using Wilson score method.   
11.4.4 Analyses of safety data 
Safety data will be presented on the safety population of the parallel-arm period and of the 
single-arm period. Treatment-emergent adverse events (TEAEs), treatment-emergent SAEs, 
treatment-emergent AESIs,  and TEAEs leading to treatment discontinuation, will be summarized 
based on the Medical Dictionary for Regulatory Activities (MedDRA) coding of verbatim terms 
reported by investigators (Section 9.2.5). 
All safety analyses will be performed using the following common rules: 
• The observation period to be used for the safety population is the TEAE period. The 
TEAE period is defined  
- 
For the parallel-arms period as the time from the first IMP injection to the day before 
the second IMP injection (for patients entering into the single arm period period) or to 
70 days after the first IMP injection, whichever comes first 
- 
For the single-arm period as the time from the first IMP injection received in the single 
arm period to 70 days after the last IMP injection. 
The following definitions will be applied to laboratory parameters, and vital signs: 
• The potentially clinically significant abnormality (PCSA) values are defined as abnormal 
values considered medically important by the Sponsor according to predefined 
criteria/thresholds based on literature review and defined by the Sponsor for clinical 
laboratory tests, and vital signs. 
• Potentially clinically significant abnormality criteria will determine which patients had at 
least 1 PCSA during the TEAE period, taking into account all evaluations performed, 
including unscheduled or repeated evaluations. The number of all such patients will be the 
numerator for the on-treatment PCSA percentage.

• Treatment period: the treatment period used for quantitative analysis is defined: 
- 
For the parallel-arms period as the time from the first IMP injection to 35 days after 
this injection or to the day before the second IMP injection (for patients entering into 
the single arm period period) whichever comes first. 
- 
For the single-arm period as the time from the first IMP injection received in the single 
arm period to 35 days after the last IMP injection. 
11.4.4.1 Analysis of the adverse event data 
The analyses of AEs will focus on TEAEs. Treatment-emergent AEs are defined as any AEs that 
are newly developed or worsened or that become serious during the TEAE period.  
Treatment-emergent AE incidence tables will present the number (%) of patients experiencing at 
least 1 TEAE by system organ class (SOC) (sorted by internationally agreed order), high-level 
group term (HLGT), high-level term (HLT) and preferred term (PT) sorted in alphabetical order. 
Multiple occurrences of the same event in the same patient will be counted only once in the tables 
within a treatment phase. The denominator for computation of percentages is the safety population 
within each auto-injector device group. 
Adverse event incidence table will be provided for all types of TEAEs: all TEAEs, all 
treatment-emergent AESI (defined with a PT or a prespecified grouping), all treatment-emergent 
SAEs and all TEAEs leading to permanent treatment discontinuation. 
Death: The following summaries will be provided: 
• Number (%) of patients who died by study period (TEAE, on-study) and reasons for death 
summarized on the safety population  
• Death in nonrandomized patients or randomized and not treated patients 
• TEAE leading to death (death as an outcome on the Adverse Event CRF page as reported 
by the Investigator) by primary SOC, HLGT, HLT and PT showing number (%) of 
patients sorted by internationally agreed order of SOC and alphabetic order of HLGT, 
HLT, and PT. 
11.4.4.2 Analysis of the laboratory data 
For laboratory data, including the incidence of PCSAs, actual values and change from baseline 
will be summarized by treatment group.  
The number and percentage of patients with at least 1 PCSA at any time during the TEAE period 
will be summarized for each laboratory parameter.  Shift tables showing changes with respect to 
the baseline status will be provided. 
The summary statistics (including number, mean, median, standard deviation, minimum, and 
maximum) of all laboratory variables will be calculated for each visit (baseline, each post-baseline 
time point, endpoint) by auto-injector device group.

11.4.4.3 Summary of the vital sign data 
The number and percentage of patients with at least 1 PCSA at any time during the TEAE period 
will be summarized for each vital signs variable. Shift tables showing changes with respect to the 
baseline status will be provided.  
The summary statistics (including number, mean, median, standard deviation, minimum, and 
maximum) of all vital signs variables will be calculated over time. 
11.4.5 Analyses of pharmacokinetic, pharmacodynamics and anti-alirocumab antibodies 
variables 
Pharmacokinetic parameters (Cmax, tmax, AUC0-tau and Ctrough) will be summarized (mean, 
geometric mean, median, standard deviation, standard error of mean, coefficient of variation, 
minimum, and maximum) for each  auto-injector device in the parallel-arms period and overall in 
the single-arm period (See Section 9.2.2). 
For PK parameters log-transformed Cmax, AUC0-tau and Ctrough, estimates and 90% CI for the ratio 
of geometric means (SYDNEY/current AI) will be provided using a linear fixed effects model 
with baseline body weight as covariate. 
Total and free PCSK9 concentrations will be summarized by visit using descriptive statistics.   
Percent and absolute change from baseline in LDL-C will be summarized descriptively for each 
auto-injector device. 
The anti-drug antibodies (ADA) status (positive/negative) and antibody titers will be summarized 
using descriptive statistics. Further details will be provided in SAP. 
11.4.6 Analyses of efficacy variables 
Lipid variables will be summarized (mean, median, standard deviation, minimum, and maximum) 
in percent and absolute change from baseline (See efficacy assessments - Section 9.2.4). 
In addition, at Week 4 only, percent change from baseline in LDL-C will be analyzed using an 
ANCOVA model to determine the estimates and 95% confidence intervals for both SYDNEY and 
AI.

13.3 
SOURCE DOCUMENT REQUIREMENTS 
According to the ICH GCP, the monitoring team must check the CRF entries against the source 
documents, except for the pre-identified source data directly recorded in the CRF. The informed 
consent form will include a statement by which the patient allows the Sponsor’s duly authorized 
personnel, the ethics committee (IRB/IEC), and the regulatory authorities to have direct access to 
original medical records which support the data on the CRFs (eg, patient's medical file, 
appointment books, original laboratory records, etc). These personnel, bound by professional 
secrecy, must maintain the confidentiality of all personal identity or personal medical information 
(according to confidentiality and personal data protection rules). 
13.4 
USE AND COMPLETION OF CASE REPORT FORMS (CRFS) AND ADDITIONAL 
REQUEST 
It is the responsibility of the Investigator to maintain adequate and accurate CRFs (according to 
the technology used) designed by the Sponsor to record (according to Sponsor instructions) all 
observations and other data pertinent to the clinical investigation in a timely manner. All CRFs 
should be completed in their entirety in a neat, legible manner to ensure accurate interpretation of 
data. 
Should a correction be made, the corrected information will be entered in the e-CRF overwriting 
the initial information. An audit trail allows identifying the modification.  
Data are available within the system to the Sponsor as soon as they are entered in the e-CRF. 
The computerized handling of the data by the Sponsor may generate additional requests (DRF) to 
which the Investigator is obliged to respond by confirming or modifying the data questioned. The 
requests with their responses will be managed through the e-CRF. 
13.5 
USE OF COMPUTERIZED SYSTEMS 
The complete list of computerized systems used for the study is provided in a separate document 
which is maintained in the Sponsor trial master file.

CLINICAL TRIAL PROTOCOL AMENDMENTS 
All appendices attached hereto and referred to herein are made part of this clinical trial protocol. 
The Investigator should not implement any deviation from, or changes to the clinical trial protocol 
without agreement by the Sponsor and prior review and documented approval/favorable opinion 
from the IRB/IEC and/or notification/approval of health authorities (competent regulatory 
authority) of an amendment, as required by local regulation, except where necessary to eliminate 
an immediate hazard(s) to clinical trial patients, or when the change(s) involves only logistical or 
administrative aspects of the trial. Any change agreed upon will be recorded in writing, the 
written amendment will be signed by the Investigator and by the Sponsor and the signed 
amendment will be filed with this clinical trial protocol. 
Any amendment to the clinical trial protocol requires written approval/favorable opinion by the 
IRB/IEC prior to its implementation, unless there are overriding safety reasons. 
In case of substantial amendment to the clinical trial protocol, approval from the health authorities 
(competent regulatory authority) will be sought before implementation. 
In some instances, an amendment may require a change to the informed consent form. The 
Investigator must receive an IRB/IEC approval/favorable opinion concerning the revised informed 
consent form prior to implementation of the change and patient signature should be re-collected if 
necessary.

Guidance on contraceptive methods  
 
Female subjects: 
Highly Effective Contraceptive Methods That Are User Dependent 
Failure rate of <1% per year when used consistently and correctlya 
• Combined (estrogen- and progestogen-containing ) hormonal contraception associated with 
inhibition of ovulationb 
− oral 
− intravaginal 
− transdermal 
• Progestogen-only hormone contraception associated with inhibition of ovulationb 
− oral 
− injectable 
Highly Effective Methods That Are User Independent 
• Implantable progestogen-only hormone contraception associated with inhibition of ovulationb  
• Intrauterine device (IUD) 
• Intrauterine hormone-releasing system (IUS) 
• Bilateral tubal occlusion 
• Vasectomized partner 
(Vasectomized partner is a highly effective contraceptive method provided that the partner is the 
sole sexual partner of the woman of childbearing potential and the absence of sperm has been 
confirmed. If not, an additional highly effective method(s) of contraception should be used. 
Spermatogenesis cycle is approximately 90 days.) 
• Sexual abstinence 
(Sexual abstinence is considered a highly effective method only if defined as refraining from 
heterosexual intercourse during the entire period of risk associated with the study drug. The 
reliability of sexual abstinence needs to be evaluated in relation to the duration of the study and 
the preferred and usual lifestyle of the subject.) 
NOTES: 
a) Typical use failure rates may differ from those when used consistently and correctly. Use should be 
consistent with local regulations regarding the use of contraceptive methods for subjects 
participating in clinical studies. It is also recommended to continue using an effective contraceptive 
method for at least 4 weeks after the last injection of IMP.

2. 1 Collection/Handling/Processing of Samples 
Collection schedule 
Per protocol 
PK Serum Sample Collection and Preparation 
• At intervals stated in the clinical study protocol, whole blood from subjects will be 
collected in 5-mL red-top vacutainer tubes (US B-D Cat #367814, European B-D Cat 
#369032) containing clot activator and no additional additives or anti-coagulant for PK 
SERUM sample preparation.  
• Collect 5 mL blood directly into 5-mL red-top vacutainer tube and invert 5 times. 
• Allow blood to clot for 30 minutes.   
• Centrifuge at approximately 1200 x g for 15 minutes to separate clot from serum. 
• Within 30 minutes after centrifugation, draw off serum very slowly with transfer pipette, 
approaching no closer than 0.5 cm of the buffy coat and taking great care not to disturb the 
buffy coat (any contamination may invalidate the assay).   
• All cryovials must be properly labeled with labels provided by CRO as per the laboratory 
manual.  
• Aliquot approximately equal volumes of serum into TWO separate 1.8-mL plastic 2D 
barcoded cryovials, one for the primary aliquot and one for the duplicate aliquot.  Do not 
exceed 1 mL of serum into each cryovial. Use one of the approved cryovials listed below. 
- 
Nunc Item # 374502 
- 
VWR: Catalog # 89233-708  
- 
ThermoFisher/USA Scientific: Catalog # 12590007 
• Freeze all cryovials immediately.  All serum samples must be stored in a -20° C or colder 
freezer that does NOT auto-defrost until the next earliest shipment. For long-term storage, 
all serum samples should be stored in a -80° C freezer. 
- 
Note:  If the site does not have a -20°C or colder freezer that does NOT 
auto-defrost, ship the serum samples on dry ice on the day of collection to CRO. 
• Sites must ship the primary aliquot in a separate shipment from the duplicate aliquot.

OVERVIEW AND INVESTIGATIONAL PLAN 
This statistical analysis plan (SAP) provides a comprehensive and detailed description of strategy 
and statistical technique to be used for the clinical study reports of MSC14864 study.  
The overall goal of this study, MSC14864, is to assess the usability of SYDNEY (New device). 
1.1 
STUDY DESIGN AND RANDOMIZATION 
This is a multicenter, randomized, open-label, 16-week study conducted in the USA, with 2 
parallel arms (parallel-arm period) for the first 4 weeks, and then only one arm (single-arm period) 
for the subsequent weeks until Week 16. 
Eligible patients will be randomly allocated to receive alirocumab 300 mg Q4W, self-administered 
using either the approved AI or the new investigational AI (SYDNEY) device for the first 
injection on Day 1. This injection will be performed at the clinical site under supervision and 
guidance by staff from the site. 
Subsequently, all patients will receive alirocumab 300 mg Q4W self-administered using only 
SYDNEY device for the injections on Week 4 (Day 29), Week 8 (Day 57) and Week 12 (Day 85) 
respectively.  
1.2 
OBJECTIVES 
1.2.1 Primary objective 
To collect 12 weeks of real-use (usability) data assessing the robustness and user interaction of 
SYDNEY, in unsupervised settings on Weeks 4, 8, and 12. 
1.2.2 Secondary objectives 
Device related: 
•
To collect real-use (usability) data assessing the robustness and user interaction of
SYDNEY and the current AI 1 mL alirocumab auto-injector device in supervised settings
on Week 0 (Day 1).
Pharmacokinetics: 
•
To compare alirocumab pharmacokinetics 300 mg Q4W administered using SYDNEY and
the current AI, from baseline until Week 4.
•
To evaluate alirocumab PK 300 mg Q4W administered using SYDNEY, until Week 16.

Pharmacodynamics: 
•
To compare the percent and absolute change in LDL-C from baseline to Week 4 using
SYDNEY and the current AI.
•
To evaluate the percent and absolute change in LDL-C from baseline to Weeks 8, 12 and
16, using SYDNEY.
Safety: 
•
To evaluate the safety and tolerability of alirocumab 300 mg Q4W, using both Auto
Injector Devices.
1.3 
DETERMINATION OF SAMPLE SIZE 
No formal sample size was calculated, the sample size is based on empirical considerations. 
Considering a drop-out rate of 10% it is planned to randomize 66 patients overall (33 in each 
group) in order to ensure 60 evaluable patients overall (30 in each group) resulting in 180 
unsupervised planned injections using SYDNEY, including the 2nd, 3rd and 4th unsupervised 
injections with SYDNEY for patients randomized in the approved AI group who will switch to 
SYDNEY group just before the second injection. 
Expecting a maximum of 3 observed PTC over the 180 injections (observed PTC rate of 1.67%) 
with SYDNEY, the upper bound of the 2-sided 95% CI calculated with the Wilson score method 
will be no higher than 5.2%.

DISPOSITION OF PATIENTS 
This section describes patient disposition for both patient study status and the patient analysis 
populations. 
Screened patients are defined as any patient who met the inclusion criteria and signed the 
informed consent. 
Randomized patients consist of all screened patients with a treatment kit number allocated and

was used. Patients treated without being randomized or treated with a double-blind treatment kit 
before the randomization will not be considered as randomized and will not be included in any 
analysis population. For patient study status, the following analyses will be performed in each 
period separately (by treatment group for parallel-arm period and overall for the single-arm 
period), if applicable: 
• Screened patients 
• Screen failure patients and reasons for screen failure 
• Nonrandomized but treated patients (if any) 
• Randomized patients 
• Patients who completed the study treatment period as per protocol 
• Patients who prematurely discontinued study treatment by main reason for permanent 
treatment discontinuation 
• Status at last study contact (Alive/ Dead) 
All critical or major deviations potentially impacting analyses, randomization, and 
drug-dispensing irregularities, and other major or critical deviations will be summarized in tables 
giving numbers and percentages of deviations by treatment group (when applicable).

randomization will be assessed separately. 
2.3.1 Modified intent-to-treat population  
The mITT population of the parallel arms period will consist of all randomized patients who 
received at least 1 dose or part of a dose of IMP during this period and who had an evaluable value 
of LDL-C at baseline and an on-treatment LDL-C value within Week 4 analysis window. Patients 
in this mITT population will be analyzed according to the auto-injector device group allocated by 
randomization (ie, as-randomized treatment group). 
The mITT population of the single arm period will consist of all randomized patients who 
continued in single arm period and received at least 1 dose or part of a dose of IMP during this 
period and who had an evaluable value of LDL-C at baseline and at least one on-treatment LDL-C 
within one of the analysis windows from Week 8 to Week 16. 
The treatment periods are defined in Section 2.1.4.5. 
2.3.2 Safety population 
The safety population of the parallel arms period will consist of all randomized patients who 
received at least 1 dose or part of a dose of IMP during this period. Patient data will be analyzed 
according to the auto-injector device actually used. 
The safety population of the single-arm period will consist of all randomized patients who 
continued in the single-arm period and receive at least 1 dose or part of a dose of IMP during this 
period. 
All safety and PTC analyses will be performed on these populations.  
In addition: 
• Nonrandomized but treated patients (if any) will not be part of the safety population, but 
their safety data will be presented separately. 
• Randomized patients for whom it is unclear whether they took the IMP will be included in 
the safety population as randomized. 
2.3.3 Pharmacokinetic populations 
The PK population of the parallel arms period will consist of all randomized patients who 
received at least 1 dose or part of a dose of IMP (safety population) and had at least one evaluable 
blood sample for PK during this period. All patients will be analyzed according to the auto-
injector device that they actually received.

The PK population of the single arm period will consist of all randomized patients who received at 
least 1 dose or part of a dose of IMP and had at least one evaluable blood sample for PK during 
this period. 
The PK population will be used for the analyses of alirocumab concentrations and PCSK9 
concentrations. 
2.3.4 Anti-alirocumab antibody population 
The ADA population of the parallel arms period will consist of all randomized patients who 
received at least 1 dose or part of a dose of IMP during this period (safety population) with an 
available ADA sample at baseline and at least one post-baseline available ADA sample during this 
period. All patients will be analyzed according to the auto-injector device that they actually 
received. 
The ADA population of the single arm period will consist of all randomized patients who receive 
at least 1 dose or part of a dose of IMP during this period (safety population) with an available 
ADA sample at baseline and at least one post-baseline available ADA sample during this period.

STATISTICAL METHODS 
2.4.1 Demographics and baseline characteristics 
Parameters described in Section 2.1.1 will be summarized on the randomized population by 
treatment group using descriptive statistics.  
Continuous data will be summarized using the number of available data, mean, standard deviation 
(SD), median, minimum, and maximum for each treatment group. Categorical and ordinal data 
will be summarized using the number and percentage of patients in each treatment group.  
Medical and surgical history will be summarized by primary SOC and HLT. The tables will be 
sorted by internationally agreed order of SOC and by the decreasing frequency of HLT based on 
the overall incidence across treatment groups. In addition all medical history of specific interest 
will be presented by treatment group. 
2.4.2 Prior or concomitant medications 
The prior and concomitant medications will be presented for the safety population. 
Medications received during the parallel-arm period will be summarized by treatment group and 
medications received during the single -arm period will be summarized overall. Medications will 
be summarized according to the World Health Organization-Drug Dictionary, considering the first 
digit of the ATC class and the first 3 digits of the ATC class (therapeutic category). All ATC 
codes corresponding to a medication will be summarized, and patients will be counted once in

each ATC category (anatomic or therapeutic) linked to the medication. Therefore patients may be 
counted several times for the same medication. 
The table for prior medications will be sorted by decreasing frequency of ATC followed by all 
other therapeutic classes based on the overall incidence across treatment groups.  In case of equal 
frequency across anatomic or therapeutic categories, alphabetical order will be used. 
The tables for concomitant medications will be sorted by decreasing frequency of ATC followed 
by therapeutic class based on the incidence in the SYDNEY group. In case of equal frequency 
across anatomic or therapeutic categories, alphabetical order will be used. 
In addition, concomitant LMTs will be summarized by pre-specified categories, chemical class or 
therapeutic class and standardized medication name. 
2.4.3 Extent of investigational medicinal product exposure and compliance 
The extent of IMP exposure and compliance will be assessed and summarized by actual device 
within the safety population for the parallel-arms period and overall for the single-arm period. 
2.4.3.1 Extent of investigational medicinal product exposure 
No duration of IMP exposure will be calculated for the parallel-arms period since patients will 
receive injection(s) at Day 1 only during this period. The proportion of patients having received 
the first injection(s) will be summarized. 
The duration of IMP exposure for the single-arm period is defined as: last IMP injection date - 
first IMP injection date during this period + 28 days (regardless of unplanned intermittent 
discontinuations) and will be described quantitatively. The number of injections received during 
the single-arm period will also be summarized. The number of patients receiving 1, 2 and 3 
injections during the single-arm period will be provided. 
2.4.3.2 Compliance  
No treatment compliance to the IMP will be calculated for the parallel-arms period since patients 
will receive injection(s) at Day 1 only during this period. For patients randomized to receive the 
current AI, it will be described whether all patients received the 2 injections as planned. 
Treatment compliance to the IMP for the single-arm period will be assessed using the mean 
injection frequency, defined for each patient, as the average number of days between 2 
consecutive injections, that is: (last injection date - first injection date during this period)/(number 
of injections -1) for patients receiving at least 2 injections during this period.

2.4.4 Analyses of endpoints 
2.4.4.1 Analysis of primary endpoint 
The primary endpoint (ie, number [%]) and types of SYDNEY-associated PTCs related to the 
unsupervised injections will be described on the safety population for the single arm period. The 
number and % of PTCs will be provided with the 95% CI using Wilson score method. If 
applicable, the number of PTCs per patient will be described. In addition the type of PTCs will be 
described. 
In addition, all the reported complaints (including complaints not confirmed as fulfilling PTC 
definition) will be described. 
2.4.4.2 Analysis of secondary endpoints  
2.4.4.2.1 Device-related endpoints 
All secondary device-related endpoints will be analyzed on the safety population using descriptive 
statistics. In addition, 95% CI for the number of PTCs, number and % of patients with any PTCs 
will be provided using Wilson score method. 
Questionnaires will be analyzed with descriptive statistics. 
2.4.4.2.2 Pharmacokinetic variables 
All analyses for PK variables will be presented by treatment group for the parallel-arms period and 
overall for the single-arm period. 
All the PK analyses will be performed using the PK population in each period.  
PK parameters (Cmax, tmax, AUC0-tau and Ctrough) will be summarized (mean, geometric mean, 
median, standard deviation, standard error of mean, coefficient of variation, minimum, and 
maximum). 
For the parallel-arms period, log-transformed Cmax, AUC0-tau and Ctrough, estimates and 90% CI 
for the ratio of geometric means (SYDNEY/ AI) will be provided using an ANCOVA model with 
treatment group (SYDNEY, AI) as fixed effect and baseline body weight as covariate.

2.4.4.2.3 Anti-drug antibodies variables 
The following summaries will be performed on the ADA population by treatment group for the 
parallel-arm period and overall for the single-arm period, taking into account all samples 
regardless of timing in relation to injections:

• 
ADA titers using descriptive statistics (median, minimum, and maximum) for positive 
ADA by time point  
•

emergent ADA positive response  
• 
Number (%) of patients with persistent/indeterminate /transient treatment-emergent ADA 
positive response  
• 
Time to onset of treatment-emergent ADA positive response using descriptive statistics. 
2.4.4.2.4 Pharmacodynamic variables (lipid variables) 
Continuous endpoints anticipated to have a normal distribution 
Continuous variables anticipated to have a normal distribution (ie, percent change in LDL-C, 
Total-C, HDL-C at Week 4) will be analyzed in the mITT population of the parallel-arm period 
using an ANCOVA model with fixed categorical effect of treatment group (SYDNEY, AI), as 
well as the continuous fixed covariate of corresponding baseline value. LS means and 95% CI will 
be provided for both SYDNEY and AI. 
Depending on the number of missing LDL-C values at Week 4, a sensitivity analysis may be 
performed using multiple imputations (with baseline LDL-C and device group factors included in 
the imputation model) using the MI SAS® procedure to impute missing data followed by 
ANCOVA model. Results will be combined using Rubin’s formulae with the SAS MIANALYZE 
procedure. 
Continuous endpoints anticipated to have a non-normal distribution 
Continuous variables anticipated to have a non-normal distribution (ie, percent change in TG at 
Week 4) will be analyzed in the mITT population of the parallel-arm period using the robust 
regression model with endpoint of interest as response variable using M-estimation (using SAS 
ROBUSTREG procedure) with treatment group (SYDNEY, AI) and corresponding baseline value 
as effects to compare treatment effects. Combined means estimates for both treatment groups with 
their corresponding 95% CIs will be provided. 
Descriptive statistics will be provided for the 4 lipid parameters at Week 8, Week 12 and Week 16 
on the mITT population of the single-arm period.

2.4.4.2.5 Safety variables 
The summary of safety results will be presented separately for the parallel-arm and single-arm 
periods. The parallel-arm period will be presented by treatment group and the single-arm period 
will be presented by overall patients. No formal inferential testing will be performed for either 
study period. Summaries will be descriptive in nature. All summaries of safety results described in 
this section will be presented for each study period respectively, unless otherwise noted. 
General common rules 
All safety analyses will be performed on the safety populations as defined in Section 2.3.2, unless 
otherwise specified, using the following common rules: 
•
Safety data in patients who do not belong to the safety population (eg, exposed but not
randomized) will be listed separately.
•
The baseline value, for both parallel arms and single arm periods, is defined as the last
available value obtained up to the date and time of the first IMP administration.
•
The PCSA values are defined as abnormal values considered medically important by the
Sponsor according to predefined criteria/thresholds based on literature review and defined
by the Sponsor for clinical laboratory tests, vital signs, and electrocardiogram (PCSA
version dated May 2014 [Appendix A]). In case the PCSA threshold is within the normal
laboratory ranges, the analysis will be done using “<Low Limit Normal” or “>ULN”
threshold instead of “<PCSA threshold” or “>PCSA threshold” respectively.
•
PCSA criteria will determine which patients had at least 1 PCSA during the TEAE period,
taking into account all evaluations performed during the TEAE period, including
nonscheduled or repeated evaluations. The treatment-emergent PCSA denominator for a
given parameter will be based on the number of patients assessed for that given parameter
at least once during the TEAE period.
•
All measurements, scheduled or unscheduled, fasting or not fasting, will be assigned to
analysis windows defined in Section 2.5.4 in order to provide an assessment for Week 4 to
Week 16 time points.
•
For quantitative safety parameters based on central laboratory/reading measurements,
descriptive statistics will be used to summarize results and change from baseline values by
visit and treatment group using analysis windows.  Summaries will also include the last
on-treatment value and the worst on-treatment value. The last on-treatment value is
defined as the last value collected during the treatment period of each study period. The
worst on-treatment value is defined as the nadir and /or the peak value during the treatment
period of each study period according to the direction (minimum or maximum) of the
abnormality as defined in the PCSA list.

2.4.4.2.5.1 Adverse events 
Generalities 
The primary focus of adverse event reporting will be on TEAEs. Pre-treatment and post-treatment 
AEs will be described separately.  
If an AE date/time of onset (occurrence, worsening, or becoming serious) is incomplete, an 
imputation algorithm will be used to classify the AE as treatment-emergent, or post-treatment. The 
algorithm for imputing date/time of onset will be conservative and will classify an AE as 
treatment emergent unless there is definitive information to determine it is pre- or post-treatment. 
Details on classification of AEs with missing or partial onset dates are provided in Section 2.5.3. 
Adverse event incidence tables will present the number (n) and percentage (%) of patients 
experiencing an AE by SOC, HLGT (when applicable), HLT (when applicable), and PT. Multiple 
occurrences of the same event in the same patient will be counted only once in the tables within a 
treatment phase. 
Sorting within tables ensures the same presentation for the set of all AEs within the observation 
period (pre-treatment, TEAE, and post-treatment). For that purpose, the table of all TEAEs 
presented by SOC and PT sorted by the internationally agreed SOC order and decreasing 
frequency of PTs within SOCs (in the SYDNEY group for the tables of the parallel-arm period) 
will define the presentation order for all other tables by SOC and PT, unless otherwise specified. 
The tables of AEs by SOC, HLGT, HLT and PT will be sorted by the SOC internationally agreed 
order and the other levels (HLGT, HLT, PT) will be presented in alphabetical order, unless 
otherwise specified. 
Analysis of all treatment-emergent adverse events 
The following TEAE summaries will be generated. 
•
Overview of TEAEs, summarizing number (%) of patients with any
- 
TEAE
- 
Serious TEAE
- 
TEAE leading to death
- 
TEAE leading to permanent treatment discontinuation
•
All TEAEs by primary SOC, HLGT, HLT, and PT
•
All TEAEs by primary SOC and PT
•
All TEAEs by treatment group regardless of relationship in one column and, in the same

Analysis of groupings of adverse events including selected adverse events of special interest: 
•
All grouping of TEAEs including AESI as listed in Section 2.1.4.5.1 will be analyzed
using selections defined in Section 2.1.4.5.1 and will be presented by SMQ/CMQ and PT
(when selection is based on SMQs/CMQs) and by SOC and PT (when selection is based
on the e-CRF tick box or HLGT/HLT). The summaries will be sorted by decreasing
incidence of PT within each SOC/SMQ (in the SYDNEY group for tables performed on
the parallel-arm period)
In addition, the following variables will be tabulated for the local injection site reactions TEAEs: 
•
Intensity of the event (mild, moderate, severe)

order within each SOC .  
• TEAEs leading to death (death as an outcome on the AE as reported by the Investigator) by 
primary SOC, HLGT, HLT, and PT. TEAEs leading to death are TEAEs that led to death 
regardless of timing of death in relation to IMP injection (i.e. death occurring in the TEAE 
period or during the post-treatment period). 
2.4.4.2.5.3 Laboratory variables 
The summary statistics (including number, mean, median, standard deviation, minimum and 
maximum) of all laboratory variables (central laboratory values and changes from baseline) will 
be calculated for each visit or study assessment (baseline, each post-baseline time point, last on-
treatment and worst on-treatment value). 
The incidence of PCSAs (list provided in Appendix A) at any time during the TEAE period will 
be summarized by biological function irrespective of the baseline level and/or according to the 
following baseline status categories: 
• 
Normal/missing 
• 
Abnormal according to PCSA criterion or criteria 
For parameters for which no PCSA criteria are defined, similar table(s) using the normal range 
will be provided. 
Drug-induced liver injury 
The liver function tests, namely AST, ALT, ALP, and total bilirubin, are used to assess possible 
drug-induced liver toxicity. The proportion of patients with PCSA values or ALT increase as 
defined in Adverse Events of Special Interests section (see Section 2.1.4.5.1) during TEAE period 
by baseline status will be displayed for each parameter. 
An evaluation of drug-induced serious hepatotoxicity with the graph of distribution of peak values 
of ALT versus peak values of total bilirubin will also be presented using post-baseline values 
during TEAE period. Note that the ALT and total bilirubin values will be presented on a 
logarithmic scale. The graph will be divided into 4 quadrants with a vertical line corresponding to 
3 x ULN for ALT and a horizontal line corresponding to 2 x ULN for total bilirubin. 
Listing of possible Hy’s law cases identified (ie, patients with any elevated ALT>3 x ULN, and 
associated with an increase in bilirubin >2 x ULN, concomitantly or not) with ALT, AST, ALP, 
total bilirubin, and if available direct and indirect bilirubin will be provided. 
The incidence of liver-related TEAEs will be summarized by treatment group. The selection of 
PTs will be based on SMQ Hepatic disorder (see Section 2.1.4.5.1).

DATA HANDLING CONVENTIONS 
2.5.1 General conventions 
The following formulas will be used for computation of parameters. 
Time from diagnosis 
Time from diagnosis (years) = (Date of informed consent - Date of diagnosis*) / 365.25. 
(*):In case the month of diagnosis would be missing, it will be put equal to JANUARY if the year 
of diagnosis equals the year of informed consent; it will be put equal to JUNE otherwise. 
Date of last dose of IMP (for single-arm period) 
The date of the last injection is equal to the last date of administration reported on injection 
administration case report form page, or missing if the last administration date is unknown. 
Renal function formulas 
eGFR value will be derived using the Modification of the Diet in Renal Disease equation:175 × 
(creatinine in µmol/L / 88.4)-1.154 × (age in years)-0.203 (x 0.742 if female, x 1.212 if race is 
"black or African American").

Lipids variables, laboratory safety variables, hs-CRP 
For data below the lower limit of quantification (LLOQ) / limit of linearity, half of the lower limit 
value (ie, LLOQ/2) will be used for quantitative analyses. For data above the upper limit of 
quantification / limit of linearity, the upper limit value (ie, upper limit of quantification will be 
used for quantitative analyses. 
Pharmacokinetic variables 
Data below the LLOQ are set to zero. 
2.5.2 Data handling conventions for secondary variables 
See Section 2.1.4. 
2.5.3 Missing data  
For categorical variables, patients with missing data are not included in calculations of 
percentages unless otherwise specified. When relevant, the number of patients with missing data is 
presented. 
Handling of baseline definition if time of first IMP injection or time of assessment at Week 0 
visit is missing 
If the time of the first IMP injection or the time of assessment at Week 0 visit is missing then the 
baseline value is defined as the last available value obtained before or on the day of the first blind 
IMP injection. 
Handling of computation of treatment duration if last IMP injection date is missing  
If the last IMP injection date is missing, the exposure duration will be left as missing.  
Handling of analysis periods if last IMP injection date is missing 
If the last IMP injection date is missing, then this date will be imputed to the earliest between 
•
the last day of the month and year, when applicable or else the 31st of December of the
year,
•
the date of the end of treatment visit (Week 12 visit for completers, early end of treatment
visit for patients who prematurely discontinued the IMP),
•
and the date of the last contact,
to determine the analysis periods end.

Handling of medication missing/partial dates 
No imputation of medication start/end dates or times will be performed. If a medication date or 
time is missing or partially missing and it cannot be determined whether it was taken prior or 
concomitantly, it will be considered a prior, concomitant, and post-treatment medication. 
Handling of adverse events with missing or partial date/time of onset 
Missing or partial AE onset dates and times will be imputed so that if the partial AE date/time 
information does not indicate that the AE started prior to treatment or after the TEAE period, the 
AE will be classified as treatment-emergent. These data imputations are for categorization purpose 
only and will not be used in listings. No imputation is planned for date/time of adverse event 
resolution. 
Handling of adverse events when date and time of first IMP injection is missing 
When the date of the first IMP injection is missing, all adverse events that occurred on or after the 
day of randomization will be considered as TEAEs. 
Handling of missing assessment of relationship of AEs to IMP 
If the assessment of the relationship to IMP is missing, then the relationship to IMP will be 
assumed as possibly related in the frequency tables, but no imputation will be done at the data 
level. 
Handling of missing severity of AEs 
If the severity is missing for 1 of the treatment-emergent occurrences of an AE, the maximal 
severity on the remaining occurrences will be considered.  If the severity is missing for all the 
occurrences, a “missing” category will be added in the summary table. 
Handling of potentially clinically significant abnormalities 
Patients with missing baseline value will be grouped in the category “normal/missing at baseline.” 
For PCSAs with 2 conditions, one based on a change from baseline value and the other on a 
threshold value or a normal range, with the first condition being missing, the PCSA will be based 
only on the second condition. 
For a PCSA defined on a threshold and/or a normal range, this PCSA will be derived using this 
threshold if the normal range is missing; eg, for eosinophils the PCSA is >0.5 GIGA/L or >ULN if 
ULN ≥0.5 GIGA/L. When ULN is missing, the value 0.5 should be used. 
Measurements flagged as invalid by the laboratory will not be summarized or taken into account 
in the computation of PCSA values.

2.5.4 Windows for time points 
Data analyzed by time point (except PK and PCSK9 variables) will be summarized using the 
analysis windows given in Table 1. These analysis windows will be applicable for all analyses, 
and they are defined to provide more homogeneous data for time point-specific analyses. For PK, 
since measurements are planned every week, e-CRF visits will be used instead of analysis 
windows.

Study days are calculated from the day of first IMP injection, the day of first open-label IMP injection being Day 1. For randomized but not treated 
patients, Day 1 is the day of randomization. 
If multiple valid values of a variable exist within an analysis window, the nearest from the 
targeted study day will be selected. If the difference is a tie, the value after the targeted study day 
will be used. If multiple valid values of a variable exist within a same day, then the first value of 
the day will be selected when time is available, else the scheduled visit will be selected. 
2.5.5 Unscheduled visits 
For pharmacodynamics, safety laboratory data, or vital signs, unscheduled visit measurements 
may be used to provide a measurement for a time point, a baseline, a last or a worst value, if 
appropriate according to their definitions. The measurements may also be used to determine 
abnormal/PCSA.
