TITLE 
A Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study to 
Evaluate the Efficacy and Safety of Alirocumab in Insulin Treated Patients 
with Type 1 or Type 2 Diabetes and With Hypercholesterolemia at High 
Cardiovascular Risk Not Adequately Controlled on Maximally Tolerated 
LDL-C Lowering Therapy (ODYSSEY DM – Insulin) 
INVESTIGATOR/TRIAL LOCATION 
Multinational - Multicenter 
PHASE OF DEVELOPMENT 
3b 
STUDY OBJECTIVE(S) 
 
Primary Objectives 
x 
To demonstrate the superiority of alirocumab in comparison with 
placebo in the reduction of calculated low-density lipoprotein 
cholesterol (LDL-C) after 24 weeks of treatment in patients with 
diabetes treated with insulin and with hypercholesterolemia at high 
cardiovascular risk not adequately controlled on maximally tolerated 
LDL-C lowering therapy 
x 
To evaluate the safety and tolerability of alirocumab in patients with 
diabetes treated with insulin 
Secondary Objective 
x 
To demonstrate that alirocumab is superior in comparison to 
placebo in its effects on other lipid parameters at Weeks 12 and 24 
(ie, measured LDL-C, non-high-density lipoprotein cholesterol 
[non-HDL-C], apolipoprotein B [Apo B], total cholesterol [TC], 
lipoprotein a [Lp(a)]), high-density lipoprotein cholesterol (HDL-C), 
triglyceride (TG) levels, triglyceride rich lipoproteins (TGRL), 
apolipoprotein A-1 (Apo A-1), apolipoprotein C-III (Apo C-III), and 
LDL particle number and size) 
STUDY DESIGN 
This is a Phase 3b randomized, double-blind, placebo-controlled study to 
assess the efficacy and safety of alirocumab administered by subcutaneous 
(SC) injection in insulin treated patients with Type 1 or Type 2 diabetes and 
with hypercholesterolemia at high cardiovascular risk not adequately 
controlled on maximally tolerated LDL-C lowering therapy. 
Patients, unless they are statin intolerant, will be taking a stable, maximum 
dose/regimen of statin therapy that is tolerated by the patient, based on the 
Investigator’s judgment, with or without other lipid modifying therapies (LMT). 
Randomization will be unbalanced (2:1, alirocumab:placebo) 
The study will be a multinational, multicenter study. 
Patients will be stratified by diabetes type (ie, Type 1 diabetes versus Type 2 
diabetes). Recruitment of patients with Type 2 diabetes will complete when 
approximately 400 patients have been randomized. Recruitment of patients 
with Type 1 diabetes will continue until approximately 100 patients have been 
randomized or the end of the targeted recruitment period (summer 2016), 
whichever comes first.

Alirocumab will be administered subcutaneously with a starting dose of 75 mg 
every 2 weeks (Q2W) for 12 weeks with a blinded uptitration to alirocumab 
150 mg Q2W at Week 12 if the LDL-C at the Week 8 visit is 70 mg/dL 
(1.81 mmol/L). Patients who have an LDL-C <70 mg/dL (1.81 mmol/L) at the 
Week 8 visit will continue with alirocumab 75 mg every two weeks until the 
end of the double-blind treatment period. 
The study consists of: 
x 
A screening period of up to 3 weeks; 
x 
A double-blind treatment period of 24 weeks; 
x 
A safety observation period (off-treatment) of 8 weeks after the end 
of the double-blind treatment period. 
Note, the Investigator will need to document in the case report form (CRF) 
any adverse events (AEs) that have occurred within 70 days of the last dose 
of IMP that (s)he is aware of. A phone visit will take place at Week 32 in order 
to ensure documentation of any AEs occurring during this period.       
Patients should be on a stable diet for glucose and lipid management 
throughout the entire study duration from screening to the Week 24 visit. 
There shall be no significant changes in nutritional composition of the diet or 
in the quantity/pattern of food consumed. Patients must be receiving 
treatment for diabetes in accordance with local/regional standards of care. 
Statin dose and dose regimen as well as dose and dose regimen of other lipid 
modifying treatment(s) (if applicable) should be stable for 4 weeks prior to the 
screening period and throughout the entire study duration, including from the 
screening visit to randomization.  
The data on lipid parameters from blood samples will be masked after 
randomization. No attempts should be made by the Investigator or patient to 
have the patient’s lipid values independently evaluated after randomization 
until after the Week 24 visit, except for the safety of the patient as per the 
Investigator’s judgment. At the end of the double-blind treatment period 
(Week 24 visit), the Investigator will continue to manage the patient’s lipids in 
accordance with standard practice. Any lipid values after randomization (eg, if 
done for patient safety) should be redacted in the source documents and not 
shared with the Sponsor. 
Duration of study treatment will be 24 weeks with the last injection 
administered at Week 22.  
Patients will visit the study site at Weeks -3, 0, 8, 12, 20, and 24 with lab work 
at each visit; in addition phone visits are scheduled at Weeks 4 and 32. Week 
8 is a critical visit because it will be the only scheduled visit where an LDL-C 
value for uptitration will be available.

STATISTICAL CONSIDERATIONS 
 
Sample size determination: 
 
 
 
 
 
 
 
 
 
 
Analysis Population: 
Randomized population includes any patients who have been allocated to a 
randomized treatment regardless of whether the treatment kit was used or 
not. 
The primary efficacy analysis population will be the ITT population, defined as 
all randomized patients who had an evaluable primary efficacy endpoint.  
The primary efficacy endpoint will be considered evaluable when both of the 
following conditions are met: 
x 
The baseline calculated LDL-C value is available 
x 
A least one calculated LDL-C value is available within one of the 
analysis windows up to Week 24. 
The mITT population (otherwise referred to as the on-treatment population) is 
defined as all randomized patients who took at least one dose or part of dose 
of the double-blind IMP injection and had an evaluable primary efficacy 
endpoint during the efficacy treatment period. 
The primary efficacy endpoint will be considered evaluable during the efficacy 
treatment period when both of the following conditions are met: 
x 
The baseline calculated LDL-C value is available

x 
At least one calculated LDL-C value is available during the efficacy 
treatment period and within one of the analysis windows up to Week 
24. 
The efficacy treatment period will be defined as: 
x 
The time period from the first double-blind IMP injection up to 21 
days after the last double-blind IMP injection. 
Patients in the ITT and mITT populations will be analyzed according to the 
treatment group allocated by randomization.  
The safety population consists of the randomized population who actually 
received at least one dose or partial dose of IMP. The safety population will 
be analyzed according to the treatment actually received. 
Separate analyses will be performed for Type 1 diabetes patients on one 
hand and Type 2 diabetes patients on the other hand. However, some 
endpoints may also be analyzed on the pooled data (Type 1 and Type 2 
diabetes patients together). These analyses will be defined later in the 
statistical analysis plan. 
Primary Analysis: 
The percent change in calculated LDL-C from baseline to Week 24 will be 
analyzed in the ITT population using a mixed-effect model with repeated 
measures (MMRM) approach. All post-baseline data available within Week 8 
to Week 24 analysis windows will be used and missing data are accounted for 
by the MMRM model. 
The model will include the fixed categorical effects of treatment group 
(placebo versus alirocumab), time point (Week 8, Week 12, Week 20, 
Week 24), treatment-by-time point interaction, as well as the continuous fixed 
covariates of baseline LDL-C value and baseline value-by-time point 
interaction. Alirocumab will be compared to placebo using appropriate 
contrasts, and the 95% confidence interval (CI) of the difference will be 
provided. 
Analysis of key secondary endpoints and other efficacy 
endpoints: 
A hierarchical procedure (concerning key secondary endpoints only) will be 
used to control the type I error and handle multiple endpoints. If the primary 
endpoint analysis is significant at the 5% alpha level, secondary endpoints will 
be tested sequentially, using the order defined in section “Key Secondary 
endpoints”.  
Continuous secondary endpoints anticipated to have a normal distribution, will 
be analyzed using the same MMRM model as for the primary endpoint with 
the continuous fixed covariates of corresponding baseline value and baseline 
value-by-time point interaction. Continuous secondary endpoints anticipated 
to have a non-normal distribution will be analyzed using multiple imputation 
approach for handling of missing values followed by robust regression. Binary 
secondary endpoints will be analyzed using multiple imputation approach for 
handling of missing values followed by logistic regression. 
Analysis of diabetes-related endpoints and other 
endpoints: 
Descriptive analyses will be performed concerning diabetes-related endpoints 
and other endpoints such as anti-alirocumab antibodies.

Safety analysis: 
Safety analysis (TEAEs, AESIs, product complaints, laboratory parameters, 
vital signs) will be descriptive, based on the safety population. The safety 
analysis will focus on the TEAE period defined as the time from the first 
double-blind dose to the last double-blind dose of IMP +70 days (10 weeks). 
Timing of the analyses: 
All the efficacy data will be available for final analysis at a cut-off date 
corresponding to the Week 24 visit of the last patient.  All the safety data will 
be available at the end of the study (Week 32). If needed for the purpose of 
scientific communication, both the efficacy and safety analyses will be 
performed at the Week 24 cut-off date and an update of the safety analysis at 
the end of the study.  If analyses are not needed at Week 24, then there will 
be only a one time analysis at the end of the study. 
DURATION OF STUDY PERIOD (per 
patient)  
The duration of the study is approximately 9 months to include a 3-week 
screening period and 24-week treatment period and an 8 week safety 
observation period. 
Patients with an SAE or an AESI should be followed until resolution, 
stabilization, or death.

a Weeks 4 and 32 are telephone visits only 
b Physical examination and Vital signs:  Height, Weight, HR, and BP. Abnormal vital signs are to be recorded as AEs only if they are medically relevant: symptomatic, requiring corrective 
treatment, leading to discontinuation of IMP and/or fulfilling a seriousness criterion. 
c Injection-training prior to randomization is performed with placebo. Investigators will have the option of providing a second placebo for alirocumab for patients who require additional 
self-injection training.  The first double-blind injection is administered at the site by the patient or a trained designated person with double-blind study treatment kit allocated by IVRS. Further 
training with double-blind treatment can be done at an additional unscheduled visit(s), as per patient or Investigator’s judgment. If a designated person changes during the course of the study, 
then the person will be trained using placebo. 
d For kit dispensation:  Along with kit dispensation, the treatment administration package should be given as well as the Patient diary and injection instruction manual, as needed. 
e Patients will be asked to additionally keep a log of the daily insulin dose for 7 days prior to each visit (including daily basal dose and daily prandial dose, as applicable). 
f Safety evaluation: Adverse Events (AEs), and product complaints regardless of seriousness or relationship to alirocumab treatment, will be collected from the time the patient signs the 
informed consent form (ICF) until the end of the study (Week 32). 
g LDL-C will be calculated using the Friedewald formula. 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. 
h Hematology includes: complete blood cell count (CBC) including hematocrit, hemoglobin, red blood cell (RBC) count, red blood cell distribution width (RDW), white blood cell (WBC) count with 
differential count, and platelets.  Chemistry includes: plasma glucose, sodium, potassium, chloride, bicarbonate, calcium, phosphorous, urea nitrogen, creatinine, uric acid, lactate 
dehydrogenase (LDH), total protein, albumin, and GGT, Hepatitis C antibody (at screening, Week 24 and in case of transaminases elevation), Hepatitis B antigen (screening only).  Note that 
any Hepatitis C antibody that returns abnormal during the study will need to be followed by confirmatory testing.  TSH values should be performed at screening for patients who are on thyroid 
hormone replacement only.  
i 
Samples to be collected only if required per judgment of the Investigator. The only exception is plasma glucose which must be collected at Week 0. 
j 
Liver panel: alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and total bilirubin 
k Pregnancy status should be checked by serum pregnancy test at screening in women of childbearing potential only.  Pregnancy status shall be assessed at Week 0 and Week 24 by urine 
pregnancy test.   
l 
Urinalysis and spot urine albumin: creatinine ratio: To be performed at screening and Week 24.  Additional urine testing to be repeated if needed based on Investigator judgment.

INTRODUCTION AND RATIONALE 
Background on Patient Populations 
This study will include adult patients with Type 1 or Type 2 diabetes on insulin therapy with 
hypercholesterolemia at high cardiovascular (CV) risk that is not adequately controlled on a 
maximally tolerated dose of statin with or without other lipid modifying therapy (LMT).   
Type 2 diabetes 
More than 380 million people worldwide have diabetes (1), most of whom will die from 
cardiovascular disease (CVD) (2, 3, 4). Compared to people without diabetes, those with diabetes 
are at higher risk of developing CVD, develop associated clinical complications and at an earlier 
age, and have shortened life expectancy by about 6 to 7 years (5, 6, 7). In addition to the high 
human cost of disease, CVD contributes greatly to the overall healthcare expenditure in these 
patients (4). 
The development of CVD in people with diabetes is a progressive process and insulin requiring 
patients with Type 2 diabetes are at even higher risk than those at an earlier stage of disease (5). 
Dyslipidemia is a major risk factor for macrovascular complications in individuals with diabetes. 
In Type 2 diabetes, the dyslipidemia includes a range of lipid abnormalities including elevated 
low density lipoprotein cholesterol (LDL-C), elevated triglycerides (TG), and reduced high 
density lipoprotein cholesterol (HDL-C) (8).While an elevation of LDL-C may be variable, 
patients often present with an elevation of small, dense LDL particles which are particularly 
atherogenic. These disturbances, particularly that of LDL-C elevation, contribute to the greater 
CV risk observed in those with diabetes compared with those without (8). Low density lipoprotein 
cholesterol is identified as the primary target of cholesterol lowering therapy (9) and is accepted 
as a valid surrogate endpoint (10, 11, 12). 
Multiple clinical trials with statins and subgroup analyses in patients with diabetes (done 
primarily in patients with Type 2 diabetes) have demonstrated that significant reductions in CV 
events can be achieved through lowering of LDL-C (13, 14, 15, 16, 17, 18). The benefits of 
further intensification of LDL-C lowering, which included patients with diabetes, were recently 
demonstrated by adding ezetimibe to a statin (19).Greater reductions in LDL-C produce greater 
reduction in CV events, and comparative data of intensive versus standard statin treatment suggest 
that the lower the LDL-C level, the greater the benefit in patients at high CV risk (20, 21, 22, 23). 
Data from a meta-analyses including over 18000 patients with diabetes suggests that, for each 
1 mmol/L (39 mg/dL) decrease in LDL-C patients with diabetes experienced a 9% reduction in 
all-cause mortality and a 13% reduction in vascular mortality over a mean follow up period of 
4.3 years (18). 
The specific LDL-C target differs depending on the guidelines consulted and the severity of risk 
experienced by the patient, but they generally recommend a target of <1.8 mmol/L (70 mg/dL) in 
patients with Type 1 and Type 2 diabetes at high CV risk or at least a 50% LDL-C reduction

(4, 5, 6, 9, 24). Despite the widespread use of statin therapies, many patients with diabetes and 
dyslipidemia remain sub-optimally treated (25, 26, 27), or may be intolerant to statin therapy, due 
to troubling side effects, and may go on to experience additional CV events. For example, in the 
latest EUROASPIRE survey, although 79% of those with diabetes were on a statin, 47% had an 
LDL-C above target (26). Similarly, in the cohort of statin-treated diabetes patients in the DYSIS 
survey, 41.3% had an LDL-C above target (27). 
Type 1 diabetes 
Type 1 diabetes is one of the most common chronic autoimmune disorders with age-adjusted 
incidence from 0.1 per 100 000 people per year in China to 40.9 in Finland. In the US, around 
15 000 children and a similar number of adults are diagnosed every year. Aside from the 
enormous psychological and health burden on the individual patients, the disease costs the 
health-care system an estimated US $14.9 billion annually (28). Type 1 diabetes is associated with 
a substantially increased risk of premature death as compared to general population. Among 
persons with diabetes who are younger than 30 years of age, excess mortality is largely explained 
by acute complications of diabetes, including diabetic ketoacidosis and hypoglycemia, while CVD 
is the main cause of death later in life (29). A recent study showed that for Type 1 diabetes 
patients with on-target glycemic control, the risk of death from CV causes was more than twice 
the risk in the general population (30). Type 1 diabetes may also be accompanied by dyslipidemia 
that may predispose an individual to precocious CVD, particularly when renal dysfunction is 
present. Although the majority of participants in statin trials had Type 2 diabetes, there was no 
evidence that the effects of statin therapy on LDL-C lowering or major vascular events in people 
with Type 1 diabetes differed from that in those with Type 2 diabetes; indeed, the reduction in 
major vascular events in people with Type 1 diabetes was statistically significant (18). 
Background to proprotein convertase subtilisin kexin type 9 
The investigational medicinal product (IMP) in this study is alirocumab, a monoclonal antibody to 
proprotein convertase subtilisin kexin type 9 (PCSK9). PCSK9 is involved in regulating the levels 
of the low-density lipoprotein receptor (LDL-R) protein. Once PCSK9 is secreted into plasma it 
directly binds to the LDL-R and promotes its degradation. The increased degradation of LDLRs 
leads to a reduced LDL particle removal and, therefore higher LDL-C circulating levels. Blocking 
PCSK9 binding to the LDL-R can potentially benefit patients with hypercholesterolemia by 
decreasing their plasma LDL-C levels (31, 32, 33, 34, 35). 
Summary of select clinical studies with alirocumab 
As of 31 December 2014, 12 Phase 3 studies were completed or had a first step analysis 
completed, with 10 evaluating alirocumab administered every 2 weeks (Q2W regimen) and 2 
evaluating alirocumab administered every 4 weeks (Q4W regimen). These studies evaluated 
heterozygous familial hypercholesterolemia (heFH) patients, patients with a range of CV risk but 
predominately high and very high risk, and patients not taking statins including statin intolerant 
patients.

Phase 3 studies that evaluated Q2W regimen – efficacy results 
Ten studies that were completed or had a first step analysis evaluating 75 mg Q2W (with possible 
up-titration to 150 mg Q2W at Week 12) and 150 mg Q2W as initiation dose/dose regimen were 
performed.  Averaged across the various studies, Alirocumab use resulted in a mean -45.6 to -
48.9% reduction in LDL-C from baseline to Week 24 in studies that investigated the up-titration 
regimen and -60.4% in studies that solely investigated 150 mg Q2W dosing, whereas control rates 
were 0.5 to 4.2% (placebo) and -19.3 to -22.3 (ezetimibe). Superiority in LDL-C reduction was 
demonstrated in all placebo-controlled studies with alirocumab administered as add-on to a 
maximally tolerated dose of statin. Superiority in LDL-C reduction was also demonstrated in all 
ezetimibe-controlled studies, with alirocumab being administered as add-on to statin, or to LMTs 
other than statin, or in monotherapy. Overall, absolute reductions in LDL-C in the range 
of -40 to -90 mg/dL (-1.03 to -2.33 mmol/L) were observed in the alirocumab treatment arms. 
LDL-C reduction observed at Week 24 was maintained over time in all the studies including those 
up to 78 weeks. In all studies, the LDL-C reduction was observed at the first LDL-C measurement 
following the first alirocumab dose at Week 4. 
Significant and clinically meaningful reductions were also observed in pro-atherogenic 
biomarkers, including non-HDL-C, Apo B, and TC. Alirocumab was also superior to placebo, and 
to ezetimibe in most studies, for the reduction in lipoprotein a (Lp[a]). Modest but consistent 
reductions in fasting TGs and increases in HDL-C were also observed with alirocumab treatment. 
Phase 3 studies that evaluated Q4W regimen – efficacy results 
Two studies EFC13786 and R727-CL-1308 (first-step analysis), have evaluated the 150 mg Q4W 
and 300 mg Q4W, respectively, as initiation dose regimen with a possible up-titration to 150 mg 
Q2W. For both studies, LDL-C reduction was observed at Week 4 was maintained over time up to 
Week 24. As with Q2W dosing, changes in Non-HDL-C, Apo B, and TC showed good correlation 
with LDL-C. 
The R727-CL-1308 (CHOICE I) study included patients with and without concomitant statin.  In 
both of these populations, there were statistically significant effects in favor of alirocumab 
300 mg Q4W with possible up-titration to 150 mg Q2W for both co-primary efficacy endpoints 
(percent change in LDL-C from baseline to Week 24 and to averaged Weeks 21 – 24). For LDL-C 
reduction, the least square (LS) mean treatment difference for alirocumab versus placebo at 
Week 24 was -52.4% and -58.7% for the no concomitant statin population and concomitant statin 
population, respectively.  The results obtained at Week 12 were consistent with those at Week 24 
for both populations, whereby the Week 12 effect assessed the sole contribution of the 300 mg 
Q4W dose regimen. Approximately 15% of patients treated with Q4W dosing who received at 
least 1 injection after Week 12 were up-titrated to Q2W dosing. 
The EFC13786 (CHOICE II) study included a vast majority of statin intolerant patients with many 
on background ezetimibe therapy. At Week 24, a statistically significant LS mean treatment 
difference for alirocumab (150 mg Q4W with possible up-titration to 150 mg Q2W) versus 
placebo of -56.4% was achieved for LDL-C reduction. The results obtained at Week 12 showed a 
statistically significant LS mean treatment difference of -44.9%, whereby the Week 12 effect

assessed the sole contribution of the 150 mg Q4W dose regimen. Approximately 50% of patients 
treated with Q4W dosing who received at least 1 injection after Week 12 were up-titrated to Q2W 
dosing. 
Clinical safety 
In the completed studies, or studies with first-step analysis, 391 patients from phase 1, and 
4300 patients from phase 2 and phase 3 have been exposed to 1 or more doses of alirocumab. 
 
 
. 
Phase 2 and phase 3 safety results 
Safety data was analyzed from pooled phase 2 and phase 3 studies with a Q2W dosing, which 
included a total of 5234 patients, of which 3340 patients were treated with alirocumab at a dose of 
75 or 150 mg Q2W.  
In the placebo-controlled and ezetimibe-controlled pooled studies, no dose relationship was noted 
for any adverse events (AEs) and there was no evidence of a pattern in the type of AEs observed. 
The percentages of patients who experienced at least 1 treatment-emergent adverse event (TEAE), 
at least 1 treatment-emergent serious adverse event (SAE) and any TEAEs leading to permanent 
treatment discontinuation were similar between the alirocumab and control groups.  
There was no safety signal observed with neurologic events and neurocognitive disorders, ALT 
increase and hepatic disorders, adjudicated CV events, diabetes mellitus, and ophthalmologic 
disorders in the alirocumab-treated group overall, but more cataracts (2.1%) were noted in 
patients treated with alirocumab who achieved 2 consecutive LDL-C values <25 mg/dL compared 
to those treated with alirocumab who did not meet this criterion (0.6%). 
The most common adverse reactions in patients treated with alirocumab were local injection site 
reactions (6.2% patients in the alirocumab group versus 4.2% in control groups in the global 
pool). Injection site reactions, influenza and pruritus were identified as adverse drug reactions 
(ADRs). Rare and sometimes serious allergic adverse reactions (eg, hypersensitivity, eczema 
nummular, urticaria, and hypersensitivity vasculitis) have been reported from clinical studies in 
patients receiving alirocumab. 
The analysis of the safety data with Q2W dosing did not suggest a safety signal as of 
31 December 2014.  
Overall, the safety profile of the alirocumab Q4W dosing regimen was similar to alirocumab 
Q2W regimen, except for the frequency and onset of injection site reactions. The reactions tended 
to occur sooner after the first drug injection, and last longer, in the alirocumab group.   
Further details on alirocumab are provided in the Investigator’s Brochure.

Rationale for this study 
The objective of the present study is to assess the efficacy and safety of alirocumab in insulin 
treated patients with Type 1 or Type 2 diabetes who currently have an LDL-C 70 mg/dL 
(1.81 mmol/L) and who, at baseline, have required, in addition to lifestyle modification, statin 
treatment with or without other LMT in order to achieve their LDL-C treatment goal, or who are 
statin intolerant. There is interest in the impact of lipid lowering therapy on measures of glycemic 
control as evidence has accumulated and suggests that the use of statin therapy is associated with 
an increased risk of diabetes. This is particularly true for people with risk factors for diabetes. 
Despite an increased relative risk of diabetes with statin therapy, the absolute risk is quite small. 
On average, it has been estimated that treatment of 255 people over a period of 4 years will result 
in 1 additional case of diabetes. 
When balancing the benefit of therapy, treating the same number of people would prevent 
5.4 vascular events (36). While this risk impacts patients with previously undiagnosed diabetes, it 
suggests that lipid lowering treatment could modulate glycemia. In fact, evidence suggests that it 
may be transmembrane cholesterol transport that imparts the added risk as a reduced prevalence 
of diabetes has been found in patients with familial hypercholesterolemia as compared to patients 
without the disease (37). As a result, understanding the impact of alirocumab on glycemic control 
in patients with diabetes is of interest. 
In the Phase 3 program, involving a total of 5293 study participants, limited information is 
available in patients with diabetes who are treated with insulin and in those patients with Type 1 
diabetes. Focusing the target population on patients with Type 1 or Type 2 diabetes treated with 
insulin will provide additional information on this potential treatment group, both from an 
efficacy and safety point of view (concomitant use of insulin and a monoclonal antibody). In 
addition, this study will provide useful information on the use of alirocumab in patients already 
familiar with self-injection. 
It should be noted that all patients, except those with statin intolerance, will be on the maximum 
dose/regimen of statin that is tolerated by the patient, based on the Investigator’s judgment, with 
or without other LMT. Those patients who are on statins and/or other LMTs at randomization 
should continue the treatments unchanged throughout the study. 
Alirocumab will be evaluated at a dose of 75 mg Q2W with an increase of dose to 150 mg Q2W if 
LDL-C values at Week 8 are not <70 mg/dL.  
It is possible that some patients in the alirocumab arm may attain LDL-C levels well below 
70 mg/dL. Persons with genetic mutations such as heterozygous form of hypobetalipoproteinemia 
linked to Apo B mutations or loss of function PCSK9 mutations have very low LDL-C levels 
throughout life and have low vascular risk, and no apparent adverse effects (35, 38, 39, 40). 
The sample size of 500 patients with treatment duration 
of 24 weeks is intended to provide a broad safety experience in this patient population and to 
assess the impact of uptitration of alirocumab on efficacy and safety parameters. The control 
group is composed of patients receiving an injectable placebo of alirocumab and is appropriate for 
the objectives of this study since it will provide the most robust assessment of efficacy and safety

of alirocumab. The use of placebo is ethically acceptable as all patients should be receiving 
standard of care treatment including maximum dose/regimen of statins that is tolerated by the 
patient, based on the Investigator’s judgment, with or without other lipid modifying agents. 
Conclusion on the benefit risk assessment with alirocumab 
Based on the clinical data available to date, treatment with alirocumab has demonstrated a 
significant LDL-C lowering effect and was generally well tolerated in a population of 
hypercholesterolemic patients with non-familial hypercholesterolemia (non-FH) or with 
heterozygous familial hypercholesterolemia (heFH), including patients with a history of 
intolerance to statin. The efficacy on LDL-C was associated with consistent results in total 
cholesterol (TC), apolipoprotein B (Apo B), non-high density lipoprotein cholesterol 
(non-HDL-C) and Apo B/Apo A-1 ratio. Reductions in Lp(a) and TG and increases in HDL-C 
were also observed with alirocumab treatment.  There was no safety signal observed with 
neurologic events and neurocognitive disorders, ALT increase and hepatic disorders, adjudicated 
CV events, diabetes mellitus, and ophthalmologic disorders. 
Injection site reactions, influenza (upper respiratory symptoms), and pruritus were identified as 
ADRs. Rare and sometimes serious allergic adverse reactions (eg, hypersensitivity, eczema 
nummular, urticaria, and hypersensitivity vasculitis) have been reported from clinical studies in 
patients receiving alirocumab. Alirocumab lowered LDL-C below 25 mg/dL in some patients. 
 
The benefit of alirocumab on CV morbidity and mortality has not yet been determined and is 
under investigation in the on-going ODYSSEY OUTCOMES trial. 
This study is being undertaken to evaluate the risk benefit profile of alirocumab in patients with 
diabetes treated with insulin, given the high CV risk of this population. Since no study in the 
ODYSSEY program (ie, the alirocumab clinical trial program) has specifically focused on 
patients with diabetes and that it included a limited number of patients on insulin these data 
should provide important information concerning the efficacy and safety of alirocumab when used 
concomitantly with insulin in this high risk group.

STUDY DESIGN 
6.1 
DESCRIPTION OF THE PROTOCOL 
This is a Phase 3b randomized, double-blind, placebo-controlled study to assess the efficacy and 
safety of alirocumab administered by subcutaneous (SC) injection in insulin treated patients with 
Type 1 or Type 2 diabetes and with hypercholesterolemia at high CV risk not adequately 
controlled on maximally tolerated LDL-C lowering therapy. The study will be multinational and 
multicenter. The study consists of a screening period of up to 3 weeks, a double-blind treatment 
period of 24 weeks, and a safety observation period of 8 weeks. 
Patients, unless they are statin intolerant, will be taking a stable, maximally tolerated dose of 
statin therapy with or without other lipid modifying therapies (LMT). Statin dose and dose 
regimen as well as dose and dose regimen of other lipid modifying treatment(s) (if applicable) 
should be stable throughout the entire study duration including for 4 weeks prior to the screening 
period, during the screening period, and from screening to randomization. Patients should be on a 
stable diet for glucose and lipid management throughout the entire study duration from screening 
to the Week 24 visit. Patients should be receiving treatment for diabetes in accordance with 
local/regional standards of care. 
Patients will be stratified by diabetes type (ie, Type 1 diabetes versus Type 2 diabetes). 
Recruitment of patients with Type 2 diabetes will complete when approximately 400 patients have 
been randomized. Recruitment of patients with Type 1 diabetes will continue until approximately 
100 patients have been randomized or the end of the targeted recruitment period (summer 2016), 
whichever comes first. 
Alirocumab will be administered subcutaneously with a starting dose of 75 mg Q2W for 12 weeks 
with a blinded uptitration to alirocumab 150 mg Q2W at Week 12 if the LDL-C at the Week 8 
visit is 70 mg/dL (1.81 mmol/L). Patients who have an LDL-C <70 mg/dL (1.81 mmol/L) at the 
Week 8 visit will continue with alirocumab 75 mg Q2W until the end of the treatment period. 
The data on lipid parameters from blood samples will be masked after randomization. No attempts 
should be made by the Investigator or patient to have the patient’s lipid values independently 
evaluated after randomization until after the Week 24 visit, except for the safety of the patient, as 
per the Investigator’s judgment. 
Patients will visit the study site at Weeks -3, 0, 8, 12, 20, and 24 with lab work at each visit; in 
addition a phone visit is scheduled at Weeks 4 and 32.

x 
a 3-week screening period from signed informed consent form (ICF) to randomization 
x 
a 24-week double-blind treatment period 
x 
a safety observation period (off-treatment) of 8 weeks after the end of the double-blind 
treatment period 
Note, the Investigator will need to document in the CRF any AEs that have occurred within 
70 days of the last dose of IMP that (s)he is aware of. A phone visit will take place at Week 32 in 
order to ensure documentation of any AEs occurring during this period. Patients with an SAE or 
an adverse event of special interest (AESI) should be followed until resolution, stabilization, or 
death. 
6.2.2 Determination of end of clinical trial (all patients) 
The end of study is defined as being the last patient last visit/contact.  
6.3 
INTERIM ANALYSIS 
If needed for the purpose of scientific communication, an analysis of efficacy and safety may be 
conducted after the last patient has completed the Week 24 visit. At that time, all the efficacy data 
will be available for final analysis. Since safety data are being collected until the end of the study 
(Week 32), if the analysis with Week 24 data is performed, an update of the safety analysis will be 
performed at the end of the study.  If analyses are not needed at Week 24, then there will be only a 
one time analysis at the end of the study.  
6.4 
STUDY COMMITTEES 
Steering committee 
The Steering Committee is composed of university-based scientists (experts in lipids field, and/or 
Endocrinology/Diabetology) with clinical and study conduct expertise, working in collaboration 
with Sponsor based scientists. The committee will provide guidance on designing and conducting 
a scientifically sound study and ensure accurate reporting of the study. The Steering Committee 
will address and resolve scientific issues if encountered during the study. They will also help with 
the study recruitment, as needed. The Steering Committee members and Sponsor based scientists 
will participate in face-to-face meetings at regular intervals throughout the study and in regularly 
scheduled teleconferences. Detailed activities and responsibilities of the Steering Committee will 
be described in the Steering Committee Charter.

SELECTION OF PATIENTS 
7.1 
INCLUSION CRITERIA 
I 01. Patients with Type 1 or Type 2 diabetes treated with insulin with LDL 70 mg/dL 
(1.81 mmol/L), not adequately controlled by a stable, maximum dose/regimen of statin that 
is tolerated by the patient (see note below) for at least 4 weeks prior to the screening visit 
(Week -3) with or without other LMT.  
Note:  The maximum dose/regimen of statin that is tolerated by the patient is the highest 
registered dose/regimen tolerated by the patient based on the Investigator’s judgment or 
concerns. Some examples of acceptable reasons for a patient taking a lower statin dose 
include, but are not limited to adverse effects on higher doses, advanced age, low body 
mass index (BMI), regional practices, local prescribing information, or concomitant 
medications. Patients may be on an alternate day dose of statin as long as the dose is 
consistently taken (eg, dose every Monday, Wednesday, Friday, etc). Concomitant 
treatment with more than 1 statin is not permitted. Patients who have documented statin 
intolerance, as judged by the Investigator, and who are no longer on statin therapy as a 
result will also be eligible for the study. The reason(s) for not being on a maximum 
dose/regimen of statin (including statin intolerance) will need to be documented in the case 
report form. 
I 02. Patients 18 years of age or legal age of majority at screening visit, whichever is greater. 
I 03. Patients diagnosed with Type 1 or Type 2 diabetes at least one year prior to the screening 
visit (Week -3).

STUDY TREATMENTS 
8.1 
INVESTIGATIONAL MEDICINAL PRODUCT(S) 
Sterile alirocumab drug product will be supplied at a concentration of 75 mg/mL and 150 mg/mL 
in an aqueous buffer, pH 6.0, containing sucrose, histidine, and polysorbate 20, both as 1 mL 
volume, in an auto-injector (also known as prefilled pen). 
Sterile placebo for alirocumab will be prepared in the same formulation as alirocumab without the 
addition of protein as 1 mL volume in a prefilled pen, for the patients to perform injection 
training, as well as for those in the placebo treatment arm. 
During the screening period, the patient (or another designated person) will have to perform a 
placebo self-injection training, using a prefilled pen, before the first administration of IMP.   
For those patients randomized to alirocumab, the initial dose is 75 mg administered 
subcutaneously once Q2W. The dose will be increased in a blinded fashion to 150 mg Q2W at 
Week 12 for patients randomized to alirocumab if the Week 8 LDL-C value is 70 mg/dL 
(1.81 mmol/L).   
Those patients randomized to placebo will be administered their injection subcutaneously Q2W 
throughout the duration of the 24-week treatment period. 
NOTE: in order to ensure the continuity of the study treatment without interruption (only in the 
event the manufacturer faces any performance or supply issues of the prefilled pen), contingency 
alternatives are: 
x in case of disruption of the 150 mg prefilled pen only, if the use of 75 mg prefilled pens is 
maintained, patients will need to administer 2 injections as follows: 
- 
2 injections of 75 mg as 1 mL each in a prefilled pen for patients receiving the 150 mg 
dose 
- 
1 injection of 75 mg as 1 mL in a prefilled pen plus 1 injection of placebo as 1 mL in a 
prefilled pen for patients receiving the 75 mg dose 
- 
2 placebo injections as 1 mL each in a prefilled pen for patients receiving placebo 
OR 
x in case of disruption of either 75 mg or 150 mg or both prefilled pens, patients will be 
switched to the use of prefilled syringes of placebo, 75 mg and 150 mg, with one injection 
of 1 mL for each of these doses 
Should this occur, the alternative IMP will be maintained until the end of the study.

Page 40 
8.1.1 Route and method of administration 
A prefilled pen training guide (auto-injector training guide) will be provided to the sites and 
instructions for use (auto-injector for use) will be provided to the patient. Each administration of 
IMP will consist of 1mL subcutaneous injection in the abdomen, thigh, or outer area of upper arm 
(ie, deltoid region). 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. 
The IMP could be administered by self-injection or by another designated person (such as a 
spouse, relative, etc). In case a designated person is due to inject alirocumab to a patient during 
the study, it must be ensured that this person has been adequately trained prior to administering 
the injection. Anyone that plans to administer the IMP must be trained by the study staff. 
Instructions should be provided to the patient (or another designated person [such as spouse, 
relative, etc] that will administer the injections) at training and as needed during the course of the 
study. Close supervision and feedback should be given at the first visit, and other visits as needed.  
The used prefilled pen will be discarded in a sharps container which will be provided to patients. 
It is recommended that the subcutaneous 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 or the outer area of upper arm, etc) 
during the study. 
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 30 to 40 minutes. Thereafter, the IMP 
should be administered as soon as possible. 
8.1.2 Timing of administration 
During the screening period, patients or the designated person will have to perform a placebo 
self-injection training using a prefilled pen, before the first IMP injection. 
At the randomization visit, the first IMP injection will be done at the site by the patient or another 
designated person (such as spouse, relative, etc) under direct site staff supervision. Patients will be 
monitored at the investigational site for at least 30 minutes after this first injection in this study. If 
the designated person changes during the course of the study, the new designated person will need 
to be trained with placebo. 
IMP subcutaneous injections will then be performed outside of the clinic, Q2W up to the last 
injection. If the injection is scheduled to take place on the same date as the site visit, then the IMP 
should be administered after the blood sampling has been completed. In exceptional cases, if a 
patient prefers to have the injection performed at the study site and provisions are able to be made 
to accommodate the administration of injections at the site, it may also be allowed.

IMP should be administered subcutaneously Q2W, ideally at approximately the same time of the 
day; however, it is acceptable to have a window period of ±3 days. The time of the day is based 
upon the patient’s preference. 
If by mistake or due to other circumstances an injection is delayed by: 
x more than 7 days from the missed date or completely missed, then the patient should 
return to the original schedule of IMP administration without administering delayed 
injections. 
x less than or equal to 7 days from the missed date, then the patient should administer the 
delayed injection and then resume the original schedule of IMP administration. 
8.2 
NONINVESTIGATIONAL MEDICINAL PRODUCTS 
The following classes of drugs are identified as non-IMP because the medication is either a 
background therapy or a potential rescue medication: 
x 
Statins, 
x 
Cholesterol absorption inhibitors (ezetimibe), 
x 
Bile acid-binding sequestrants (such as cholestyramine, colestipol, colesevelam), 
x 
Nicotinic acid, 
x 
Fibrates (such as Fenofibrate), 
x 
Omega-3 fatty acids (1000 mg daily), 
x 
Insulins.  
Please see Section 8.8 for further information. All fibrates are allowed at entry if the patient has 
tolerated the medication and remained on a stable dose. Background LMT and insulin will not be 
provided by the Sponsor. Patients will obtain these medications in compliance with local 
regulations. 
8.3 
BLINDING PROCEDURES 
Alirocumab and placebo for alirocumab will be provided in identically matched prefilled pens and 
packaged identically, which includes labeling to protect the blind. Each treatment kit will be 
labeled with a number which will be generated by a computer program from Sanofi. The 
treatment kit numbers will be obtained by the Investigator at the time of patient randomization 
and subsequent patient visits scheduled via IVRS/IWRS that will be available 24 hours-a-day, 
7 days-a-week. 
In accordance with the double-blind design, study patients, Investigators and study site personnel 
will remain blinded to study treatment and will not have access to the randomization (treatment 
codes) except under circumstances described in the following subsections.

8.3.1 Methods of blinding 
8.3.1.1 Adverse event 
The treatment code will be unblinded by the Pharmacovigilance Department for reporting to the 
Health Authority of any Suspected Unexpected Serious Adverse Reaction (SUSAR), ie, any 
Serious Adverse Event that is both unexpected (per the specific section of the CIB) and 
reasonably associated with the use of the IMP according to either the judgment of the Investigator 
and /or the Sponsor. 
Refer to Section 10.5 for suspected unexpected ADR unblinding by the Sponsor and Section 8.3.2 
(Randomization code breaking during the study) for unblinding an AE under exceptional 
circumstances when knowledge of the Investigational Medicinal Product is essential for treating 
the patient. 
8.3.1.2 Lipid parameters 
Lipid parameter values from blood samples obtained after the randomization visit, run by the 
central lab, will not be communicated to the sites so that they cannot deduce the treatment group 
of their patients based on LDL-C level attained.  The sponsor’s operational team will not have 
access to lipid parameters associated with patient identification until after the final database lock 
has occurred. For safety purposes, TG alerts for TG values 500 mg/dL any time after 
randomization will be sent to the Investigator (Section 8.8.1 and Section 9). 
At the end of the double-blind treatment period (Week 24 visit) the Investigator will continue to 
manage the patient’s lipids in accordance with standard practice. Any lipid values after 
randomization should be redacted in the source documents and not shared with the Sponsor. 
8.3.1.3 Anti-alirocumab antibodies 
Patient anti-alirocumab antibody results will not be communicated to the sites while the study is 
ongoing. 
The sponsor’s operational team will not have access to anti-alirocumab antibody results associated 
with a patient identification number until after the final database lock has occurred. 
The lab technicians involved in the determination of patient anti-alirocumab antibody titers are 
excluded from the operations team and a process will be set up to prevent any potential 
unblinding. 
8.3.2 Randomization code breaking during the study 
In case of an AE, the code should only be broken in circumstances when knowledge of the IMP is 
required for treating the patient. If possible, contact should be initiated with the Monitoring 
Team/Study Physician before breaking the code. All calls will be documented by the Monitoring 
(electronic

Team as appropriate to include date and time of the call, name of the person contacted within the 
Monitoring Team, patient ID, documentation of the request, and decision for unblinding or not. 
Code breaking can be performed at any time by using the proper module of the interactive voice 
response system (IVRS)/interactive web response system (IWRS), depending on which system is 
used for the site, and/or by calling any other phone number provided by the Sponsor for that 
purpose. However, it is preferable to contact the Study Physician to discuss the case before 
unblinding the case. If the blind is broken, the Investigator should document the date, time of day, 
and reason for code breaking, and report this information on the appropriate page of the e-CRF.  
Note that when documenting the reason for unblinding, the Investigator must not provide any 
detail regarding the nature of the IMP. The Investigator should not divulge IMP detail to the 
Sponsor’s representative or to any staff members until database closure. Furthermore, when 
completing forms (eg, AE, SAE), the study treatment should not be disclosed on the forms.   
The code-breaking material will be also kept at the entity responsible for the “24 hour alert 
system”; but this system should be used in very exceptional cases only (ie, unavailability of 
IVR/IWR system or inability to contact Investigator and/or site staff). However, the preferred 
option is to unblind using IVRS. The Investigators will be informed by the clinical monitoring 
team about the availability of the local code-breaking material. A patient card, including the 
relevant “24 hour alert system” telephone number will be provided to every patient who will 
participate in the study. Unblinding may also be performed by the Sponsor for some SAEs in 
order to conform to regulatory reporting requirements (ie, for some SAEs that are both related and 
unexpected). 
If the code is broken, the patient must permanently discontinue IMP administration.

METHOD OF ASSIGNING PATIENTS TO TREATMENT GROUP 
The randomized list of treatment kit numbers will be generated centrally by Sanofi. The IMP 
(alirocumab 75 or 150 mg kits, or placebo kit) will be packaged in accordance with this list. 
The Trial Supply Operations 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 treatments to the 
patients. 
Patients will be randomized to receive either placebo or alirocumab during the double-blind 
treatment period. The randomization ratio alirocumab:placebo will be 2:1. For each randomized 
patient, there will be several corresponding treatment kit numbers (resupply visits), which will be 
allocated through the centralized treatment allocation system. The randomization is stratified by 
diabetes type (ie, Type 1 versus Type 2). 
The treatment kit numbers will be allocated using the centralized treatment allocation system on 
randomization visit (Day 1, Week 0), and then at Week 12 as re-supply visits, and at unscheduled 
visits if needed.

Page 44 
For patients in the alirocumab treatment arm, the treatment kit allocated at Week 12 will be based 
on their Week 8 LDL-C level following the up-titration rules (see Section 6.1). Regular transfer of 
data will be planned between the central laboratory and the centralized treatment allocation 
system provider in order to proceed in a blinded manner for study sites and sponsor. 
Before randomizing a patient, the Investigator or designee will have to contact the centralized 
treatment allocation system. 
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, then the patient will be considered as not 
randomized and withdrawn from the study. 
Two types of centralized treatment allocation systems will be used, the IVRS and the IWRS 
depending on the choice of the site. 
8.5 
PACKAGING AND LABELING 
For the double-blind treatment period, each double-blind treatment kit, either alirocumab or 
placebo for alirocumab, will be prepared to contain 6 prefilled pens in a child resistant package.  
In order to protect the blind, all double-blind treatment kit boxes for injection will have the same 
look and feel and therefore will be labeled with a double-blind label. 
In addition to the double-blind treatment kits for injection, a training kit containing 1 placebo for 
alirocumab prefilled pen will be prepared for the purpose of instructing patients on injection 
administration which is to be performed prior to randomization at screening visit (Week-3, 
Visit 1). If deemed necessary, a second injection training with placebo for alirocumab can be 
performed using an additional training kit prior to randomization. Injection training with placebo 
will be performed and documented in the CRF, including if the designated person who 
administers IMP to the patient changes during the course of the study. 
Packaging is in accordance with the administration schedule. The content of the labeling is in 
accordance with the local regulatory specifications and requirements. 
8.6 
STORAGE CONDITIONS AND SHELF LIFE 
Investigators or other authorized persons (eg, pharmacists) are responsible for storing the IMP in a 
secure and safe place in accordance with local regulations, labeling specifications, policies, and 
procedures. 
Control of IMP storage conditions, especially control of temperature (eg, refrigerated storage) and 
information on in-use stability and instructions for handling the IMP should be managed 
according to the rules provided by the Sponsor.

The IMP will be stored in a refrigerator between +2°C and +8°C (36°F to 46° F) at the site. The 
temperature of the site refrigerator should be checked daily and recorded on a log sheet. 
The IMP that will be stored at the investigational site should be kept in an appropriate locked 
room, under the responsibility of the Investigator or designee or other authorized person in 
accordance with the storage conditions indicated on the label. 
After the supply of IMP kits to patients at the study site visits, appropriate provisions will be in 
place for transportation of the IMP kits from the study site to the patient’s refrigerator. 
8.7 
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 Investigator's prescription 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. 
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 IMP and eliminate potential hazards. 
Under no circumstances will the Investigator supply IMP to a third party, 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 
Measures taken to ensure and document IMP compliance and accountability are described below: 
x 
The Investigator or designee will obtain via IVRS/IWRS the treatment kit number(s) and 
he/she will dispense the treatment kit(s) to the patient. 
x 
The Investigator or designee will enter the treatment kit packaging number(s) and the kit 
numbers in the e-CRF. 
x 
IMP administration data will be recorded by the patients onto a Patient diary 
x 
Used pens (sharps container) and the treatment kit dispensed at the previous dispensation 
visit are brought back by the patient at IMP kit re-supply visits only 
x 
The Investigator or designee counts the number of remaining unused prefilled pens in the 
returned packs and fills in the Treatment Log Form at IMP kit re-supply visits;

x 
The monitor will check the data consistency between e-CRF pages and treatment log 
forms using the patient diary and returned, unused prefilled pen 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. 
8.7.2 Return and/or destruction of treatments 
A detailed treatment log of the destroyed IMP will be established with the Investigator (or the 
pharmacist) and countersigned by the Investigator and the monitoring team. The Investigator will 
not destroy the unused IMP before the Sponsor provides written authorization. 
Sharp containers containing all used pens will be brought back to the site by the patient for the 
purpose of destruction. 
If the site is not able to destroy or destruction is not allowed in the country, all treatments kits will 
be retrieved by the Sponsor. A detailed treatment log of the returned IMP will be established with 
the Investigator or designee and countersigned by the Investigator and the Monitoring Team. 
8.8 
CONCOMITANT MEDICATION 
A concomitant medication is any treatment received by the patient concomitantly during the 
study, until Week 32. 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. 
Nutraceutical products or over-the-counter therapies that may affect lipids are allowed (see 
Section 8.8.3 for exceptions) only if they have been used at a stable dose for at least 4 weeks prior 
to screening visit, during the screening period and during the 24 weeks of the double-blind 
treatment period. Examples of such nutraceutical products or over-the-counter therapies include 
omega-3 fatty acids at doses <1000 mg, plant stanols such as found in Benecol, flax seed oil, and 
psyllium. 
8.8.1 Management of background lipid-modifying therapy 
For background LMT, including statins, sites must follow the national product label for the safety 
monitoring and management of patients. 
Patients will be on stable, maximum dose/regimen of statin therapy that is tolerated by the patient 
with or without other LMT during the study as indicated in Section 7.

Page 47 
Lipid profile values will be blinded from samples obtained after randomization. Nevertheless, for 
safety reasons, sites will be made aware of TG alerts, in order to make decisions on the patient’s 
background LMT (Section 9). 
From the screening visit (Week -3) until the Week 24 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 
(including but not limited to a TG alert posted by the central lab) warrant such changes, as per the 
Investigator’s judgment. For a TG alert that has been confirmed by repeat testing, the Investigator 
should perform investigations, manage the patient, and modify the background LMT as per 
his/her medical judgment. 
While all fibrates are allowed at entry if the patient has tolerated the medication and remained on 
a stable dose, should the patient require the introduction of a fibrate during the course of the study 
(ie, as rescue treatment in response to a TG alert) 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 and for at least 10 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 Harmonisation 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 
EOT visit): 
x 
Red yeast rice products 
x 
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 
endpoint assessment. 
8.8.4 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 
Lipid parameters 
Blood sampling to determine lipid parameters (ie, TC, LDL-C, HDL-C, TG, non-HDL-C, Apo B, 
Apo A-1, ratio Apo B/Apo A-1, Apo C III, LDL particle size and number, and Lp [a]) 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. 
TC, HDL-C, TG, Apo B, Apo A-1, Apo C-III and Lp(a) will be directly measured by the Central 
Laboratory as per the schedule in Section 1.2. LDL-C will be directly measured via beta 
quantification method by the Central Laboratory as per the schedule in Section 1.2. LDL-C will 
be calculated using the Friedewald formula at all visits (except Weeks 4 and 32). 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. Non-HDL-C will be calculated by 
subtracting HDL-C from the TC. Ratio Apo B/Apo A-1 will be calculated. Triglyceride rich 
lipopoprotein will be calculated by total cholesterol minus HDL cholesterol minus LDL 
cholesterol. Detailed procedures of sample preparation, storage and shipment will be described in 
the specific laboratory manual which will be provided to sites. 
 
All patients will qualify for randomization based on the LDL-C value obtained at Week -3 visit. If 
the patient is not fasting at this or any other visit requiring fasting, then he/she will be asked to 
come the day after or as close as possible to this date for the blood sampling.  
Communication of lipid results by central lab 
The lipid results from blood samples obtained after the randomization visit will not be 
communicated to the Investigators. However, sites will be notified in the event of a TG level 
500 mg/dL (5.65 mmol/L) obtained any time after randomization (ie, TG alert). Repeat testing 
should be done as soon as possible after a TG alert. For a confirmed TG alert, please refer to 
relevant information in Section 8.8.1. 
Efficacy endpoints will not be considered as AEs, such as those involving abnormalities in lipid 
levels, unless meeting the criteria in Section 10.4. 
9.1 
PRIMARY ENDPOINTS 
9.1.1 Primary efficacy endpoint 
The primary efficacy endpoint is the percent change in LDL-C from baseline to Week 24 in the 
intent-to-treat (ITT) population, using all LDL-C values regardless of adherence to treatment (ITT 
estimand). The percent change is defined as:

100x (calculated LDL-C value at Week 24 - calculated LDL-C value at baseline)/calculated 
LDL-C value at baseline. 
The baseline calculated LDL-C value will be the last LDL-C level obtained before the first 
double-blind IMP injection. The calculated LDL-C at Week 24 will be the LDL-C level obtained 
within the Week 24 analysis window.  
All calculated LDL-C values (scheduled or unscheduled, fasting or not fasting) between Weeks 8 
to 24 may be used to provide a value for the primary efficacy endpoint, if appropriate, according 
to above definition.  
The analysis window used to allocate a time point to a measurement will be defined in the SAP.  
9.1.2 Primary safety endpoints 
Safety parameters (AEs, laboratory parameters, vital signs) will be assessed throughout the study. 
The observation of safety data will be as follows: 
x 
Pre-treatment period is defined from the signed informed consent up to the first dose of 
double-blind IMP injection. 
x 
Treatment Emergent Adverse Event (TEAE) period is defined as the time from the first 
dose of double-blind IMP injection to the last dose of IMP injection + 70 days (10 weeks) 
as residual effect of treatment is expected until 10 weeks after the stop of double-blind 
IMP. 
x 
Post-treatment period is defined as the time starting the day after the end of the TEAE 
period up to resolution/stabilization of all SAE and AESI, whichever comes last. 
9.1.2.1 Adverse events 
All AEs diagnosed by the Investigator will be reported and described.  
All AEs will be coded to a “Lowest Level Term (LLT)”, “Preferred Term (PT)”, “High Level 
term (HLT)”, “High Level Group Term (HLGT)” and associated primary “System Organ Class 
(SOC)” using the version of MedDRA (Medical Dictionary for Regulatory Activities) currently in 
effect at Sanofi at the time of the considered database lock. 
Adverse events/AESIs, SAEs, and product complaints will be collected from the time the patient 
signs the ICF to the last scheduled study visit, as applicable.  
Definitions for AEs, SAEs, and AESI, as well as obligation for reporting are further defined in 
Section 10.4.

STUDY PROCEDURES 
The window period for Week 0 is +3 days.  The window period for Weeks 8, 12 and 24 is 
±3 days. The window period for Weeks 4, 20, and 32 is ±7 days. 
For all visits after Day 1/inclusion visit, if one visit date is changed, then the next visit should take 
place according to the original schedule as outlined in the Study Flow Chart (Section 1.2). 
Blood sampling 
All blood sampling, including the blood sampling for determination of lipid parameters (eg, TC, 
LDL-C, HDL-C, TG, non-HDL-C, Apo A, Apo B, Apo C-III, Lp(a), LDL particle size and 
number) and also for plasma glucose should be performed in the morning, in fasting condition (ie, 
overnight, at least 10 to 12 hours fast and refrain from smoking), and before IMP injection for all 
site visits throughout the study. Alcohol consumption within 48 hours and intense physical 
exercise within 24 hours preceding the blood sampling are discouraged. 
Note: if the patient is not in fasting conditions, the blood sample will not be collected and a new 
appointment will be given to the patient for the day after (or as close as possible to this date), with 
instructions to fast (see above conditions). 
Laboratory tests 
The laboratory data are collected in accordance with the study schedule and the details provided 
in the Study Flow Chart (Section 1.2). 
x Hematology: all visits except Weeks 4 and 20; may be performed at Week 0 as applicable 
and based on the clinical discretion of the Investigator 
x Chemistry: all visits except Visits 3 and 6; may be performed at Week 0 as applicable and 
based on the clinical discretion of the Investigator, except for plasma glucose which 
should be performed at Week 0 for all patients 
x HbA1c: screening and Weeks 0, 12, and 24 
x Lipid panel: screening and Weeks 0, 8, 12, 20, and 24 
x Measured LDL-C via beta quantification: Weeks 0, 12, and 24 
x Other lipid assessments (Apo B, Apo A-1, Apo C-III, LDL particle size and number, 
Lp[a]): Weeks 0, 12, and 24 
x Liver panel: all visits except Visits 3 and 6; may be performed at Week 0 as applicable and 
based on the clinical discretion of the Investigator. In case of total bilirubin values above 
the normal range, differentiation into conjugated and non-conjugated bilirubin will occur 
automatically 
x Creatine Phosphokinase (CPK): all visits except Visits 3 and 6; may be performed at

x C-peptide: screening only 
x PCSK9 levels will be performed only at Week 0. 
x Anti-alirocumab antibodies (Week 0, Week 12, and Week 24).  
Urine samplings 
Urinalysis will be performed at screening and Week 24 visits. Dipstick will be performed and will 
assess for pH, specific gravity, and for the presence of blood, protein, glucose, ketones, nitrates, 
leukocyte esterase, uro-bilinogen and bilirubin. If the dipstick is abnormal then standard 
microscopy will be conducted. Microscopy will evaluate for the presence of red blood cells 
(RBC), RBC clumps, white blood cells (WBC), WBC clumps, epithelial cells (transitional, renal 
tubular, and squamous), casts (hyaline, epithelial, WBC, RBC, granular, fatty, cellular, broad, 
waxy), crystals (triple phosphate, calcium oxalate, calcium phosphate, calcium carbonate, uric 
acid, amorphous, ammonium biurate, bilirubin, leucine, tyrosine, cystine), bacteria, 
yeast- budding, yeast-hyphae, trichomonas, oval fat body, fat, mucous, and sperm. 
Spot urine testing will be performed for albumin and creatinine to calculate the albumin: 
creatinine ratio at the screening and Week 24 visits. 
Notes: Any clinically relevant abnormal laboratory value should be immediately rechecked for 
confirmation before making any decision for the concerned patient. It should be documented as an 
AE/AESI/SAE if one or more criteria in Section 10.4 are met.  
Decision trees for the management of certain laboratory abnormalities by Sanofi are provided in 
Appendix C and should be followed by Investigators. 
Physical examination 
A general physical examination should be performed at the time points indicated in the study 
schedule flowchart (Section 1.2). If a new clinically significant abnormality or worsening from 
baseline is detected after inclusion, then an AE should be reported and the patient should be 
considered for further clinical investigations and/or specialist consultation, as per the 
Investigator’s medical judgment.

Blood pressure/heart rate  
Blood pressure (BP) should be measured in sitting position under standardized conditions, 
approximately at the same time of the day, on the same arm, with the same apparatus (after the 
patient has rested comfortably in sitting position for at least 5 minutes). Values are to be recorded 
in the e-CRF; both systolic BP and diastolic BP should be recorded. At the first screening visit, 
BP should be measured in both arms. The arm with the highest diastolic pressure will be 
determined at this visit, and BP should be measured on this arm throughout the study. This highest 
value will be recorded in the e-CRF. 
Heart rate will be measured at the time of the measurement of BP. 
Notes: in case of high BP values, the Investigator is responsible for the optimization of the 
patient’s treatment to achieve BP targets as defined by local guidelines/regional standards of care. 
Body weight and height 
Body weight should be obtained with the patient wearing undergarments or very light clothing 
and no shoes, and with an empty bladder. The same scale should be used throughout the study. 
Height needs to be measured, as self-reported heights are not acceptable. 
  
 
Insulin log 
Patient should be instructed to complete the insulin log in order to record his/her daily insulin 
dose (for basal insulin and for prandial insulin, as applicable) for at least 7 days prior to each visit, 
and to bring this information to the next study visit. The patient may record the daily insulin dose 
for more than 7 days prior to the study visits, however only the information collected for the last 
7 days prior to each visit will be entered into the CRF. 
10.1 
VISIT SCHEDULE 
10.1.1 Screening period 
Only patients who meet the inclusion criteria as noted in Section 7.1 should be screened. The 
screening period will take place up to 3 weeks or 21 days prior to randomization/Day 1 visit. 
Please note that every effort should be made to ensure that the screening window is as short as 
possible. If it is planned to have another designated person administer the injections to the patient 
during the study, then this person should be present for injection training.

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 CRF. In any case, the 
patient should remain in the study as long as possible.

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 7.1 and 
Section 7.2). 
For all temporary treatment discontinuations, duration should be recorded by the Investigator in 
the appropriate pages of the CRF.  
Temporary treatment discontinuation is defined as one or more scheduled injections that are not 
administered to the patient as decided by the Investigator. 
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 CRF or 
e-CRF. Patients should discontinue IMP for the following reasons: 
x Pregnancy, intention for pregnancy, or no longer with effective contraceptive method of 
birth control (females only). 
x Acute injection reaction of clinical concern. 
x SAE (or non-serious but severe in intensity) of hypersensitivity reaction considered related 
to IMP. 
x At patient request. 
x If, in the Investigator's opinion, continuation with the administration of the IMP would be 
detrimental to the patient's well-being. 
x Intercurrent condition that requires discontinuation of the IMP (eg, laboratory 
abnormalities, please refer to decision tree in Appendix C). 
x At the specific request of the Sponsor. 
x Any code breaking requested by the Investigator. 
x Patient receives double-blind treatment prior to randomization

Page 64 
Any abnormal laboratory value will be immediately rechecked for confirmation (within 24 hours 
if possible), 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 who prematurely discontinue study treatment (regardless of the reason) should still 
continue the study and undergo all visits and procedures as described in Section 1.2 with the 
exception of study treatment administration and its associated procedures. At the time of treatment 
discontinuation, the patient should have, as soon as possible, an unscheduled visit with 
assessments normally planned at EOT visit (this should take place within 5 days of treatment 
discontinuation, if possible) and then resume the original study schedule until end of study. 
If after treatment discontinuation, the patient refuses to resume the original study schedule until 
the end of the study, then if possible, the patient should undergo an unscheduled visit with 
assessments normally planned at the EOT visit (it should take place within 5 days of treatment 
discontinuation, if possible). The patient, at a minimum, should then be followed-up for at least 
10 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 phone visit will take place 
10 weeks after the premature discontinuation. 
All definitive discontinuation of study treatment should be recorded by the Investigator in the 
appropriate pages of the CRF when considered as confirmed. IVRS/IWRS should be notified 
when a patient prematurely discontinues study treatment. 
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. 
If possible, the patients are assessed using the procedure normally planned for the EOT visit. 
For patients who fail to return to the site, the Investigator should make the best effort to recontact 
the patient (eg, contacting patient’s family or private physician, reviewing 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). 
The statistical analysis plan will specify how the primary endpoints of patients who are lost to 
follow-up will be considered. 
Patients who have withdrawn from the study cannot be rerandomized (treated) 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 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 
An SAE is any untoward medical occurrence that at any dose: 
x 
Results in death, or 
x 
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. 
x 
Requires inpatient hospitalization or prolongation of existing hospitalization, or 
x 
Results in persistent or significant disability/incapacity, or 
x 
Is a congenital anomaly/birth defect 
x 
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 as 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 
- 
ALT >3 x ULN + total bilirubin >2 x ULN or asymptomatic ALT increase >10 x ULN 
- 
Suicide attempt or any event suggestive of suicidality

Chronic neurodegenerative diseases (newly diagnosed) or aggravated during the study  
- 
Suspected transmission of an infectious agent, if any suspected transmission of an 
infectious agent via a medicinal product (eg, product contamination) 
10.4.1.3 Adverse event of special interest 
An AESI is an AE (serious or non-serious) that needs to be monitored, documented, and managed 
in a pre-specified manner described in the protocol (Appendix B). 
For this study, the AESI are:  
x Increase in ALT: 
ALT 3 x ULN (if baseline ALT <ULN) Or ALT 2 times the baseline value (if baseline 
ALT ULN) (Appendix C). 
x Allergic events. 
- 
Allergic drug reactions and/or local injection site reactions deemed to be allergic by 
the Investigator (or have an allergic component), 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. 
x Pregnancy: 
- 
Pregnancy occurring in a female patient or the partner of a male patient (if permitted 
by the female partner and by local regulatory authorities) during the study or within 
70 days following the last dose of study drug.  
- 
Pregnancy will be recorded as AESI in all cases. Pregnancy will be qualified as an 
SAE only if it fulfils one or more SAE criteria.   
- 
In the event of pregnancy of a female patient included in the study, study product 
should be discontinued.   
- 
The follow-up of the pregnancy will be mandatory until the outcome has been 
determined.   
x Symptomatic overdose with IMP: 
- 
An overdose (accidental or intentional) is an event suspected by the Investigator or 
spontaneously notified by the patient (not based on systematic injection counts) and 
defined as at least twice of the intended dose within the intended therapeutic interval 
(ie, 2 or more injections are administered in <7 calendar days), to be reported using the 
Term “symptomatic OVERDOSE (accidental or intentional), indicating the 
circumstance in parentheses (eg, “symptomatic overdose [accidental]” or

“symptomatic overdose [intentional]”). The patient should be monitored and 
appropriate symptomatic treatment instituted. 
- 
The circumstances of the overdose should be clearly specified in the verbatim and 
symptoms, if any, entered on separate AE/SAE forms.  
- 
Of note, asymptomatic overdose should be reported as a standard AE.  
x 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. 
x Neurocognitive events 
- 
All neurocognitive events will be considered as AESI 
10.4.1.4 Local injection site reactions 
Local injection site reactions that are considered by the Investigator as non-allergic events and 
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 E.  
10.4.1.5 Device deficiency 
A device deficiency is any inadequacy related to the identity, quality, durability, reliability, safety 
or performance of the medical device including malfunctions, use errors, and inadequate labeling. 
Product Complaints: 
x A product complaint is defined as any written, electronic, or oral communication that 
alleges deficiencies related to the identity, quality, durability, reliability, safety, efficacy or 
performance of a product after it is released for distribution. Patients will be instructed to 
contact their site for any questions or difficulties. 
x All product complaints must be reported on a product complaint form when there is a 
reason to suspect a problem with the device. 
x In case of a product complaint associated with the occurrence of an AE, the AE must be 
documented on an AE page in the CRF.

x In the case of a product complaint associated with the occurrence of a SAE, the SAE must 
be reported as in Section 10.4.3 in accordance with the SAE reporting procedures 
x Please note that all product complaints require reporting within 24 hours (please refer to 
Appendix B). 
10.4.2 General guidelines for reporting adverse events 
x All AEs, regardless of seriousness or relationship to IMP/NIMP, spanning from the 
signature of the ICF 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 CRF. 
x All product complaints associated or not to an AE are to be recorded immediately on the 
corresponding products (study medical device) complaints pages and reported to the local 
Complaint Service immediately (within 24 hours). 
x Whenever possible, a 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).  
x 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 for certain events, such as SAEs/AESI, 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.  
x When treatment is prematurely discontinued, the patient’s observations will continue until 
the end of the study as defined by the protocol for that patient, if possible. 
x Laboratory or vital sign 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  
- 
Fulfilling a seriousness criterion, and/or

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. If 
for any reason, results of lipid values are indicated on any source documents (done for the 
safety of a patient in exceptional circumstances only), all such information should be 
redacted.

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.

copy of a source document provided to the Sponsor. For laboratory results, include the 
laboratory normal ranges  
x 
All further documentation should be sent 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. 
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. 
10.4.4 Guidelines for reporting adverse events of special interest  
For each defined AESI the Investigator must make every attempt to collect additional specific 
information such as:

x Expected list of associated signs and symptoms. 
x Corrective actions (eg, treatment discontinuation, concomitant treatment). 
x Diagnostic actions (eg, test(s) or procedure(s) results).

x Sequelae. 
For these AEs, the Sponsor must be informed immediately (ie, within 24 hours), as per SAEs 
notification described in Section 10.4.4, even if not fulfilling a seriousness criterion, using the 
corresponding screens in the e-CRF. Please refer to Section 10.4.1.3 for a listing of AESI and

10.4.5 Guidelines for management of specific laboratory abnormalities 
The following laboratory abnormalities should be monitored, documented, and managed 
according to the related flow chart in Appendix C. Reporting instructions are provided in 
Appendix B. 
x 
Neutropenia 
x 
Thrombocytopenia 
x 
Increase in ALT 
x 
Acute renal insufficiency 
x 
Increase in CPK (other than cardiac-related) and suspicion of rhabdomyolysis 
Investigators are strongly encouraged to follow these algorithms in Appendix B and Appendix C, 
especially in situations where the abnormality persists or when there is no clear explanation for 
the observed abnormality. However there may be situations where these algorithms are not 
entirely applicable; therefore, the Investigator may use his/her best judgment. Also, in some 
situations, the Sponsor may wish to discuss with the Investigator. Examples where these 
algorithms may not be applicable include, but are not limited to, the following situations: 
x Patients with known stable, low or borderline neutrophil count at baseline 
x Patients with known stable, low or borderline platelet count at baseline 
x Patients with impaired renal function at baseline 
The Investigator should attempt to have a diagnosis for the observed finding and should use 
his/her best judgment as whether to or not enroll such patients, and if the patient is enrolled, how 
to best monitor these baseline abnormalities throughout the study.  
Additional examples where these algorithms may not be applicable include, but are not limited to, 
the following situations: 
x Patients with ALT increase for which the abnormality resolves following statin dose 
reduction or statin discontinuation

x Patients with elevated creatinine kinase for which the abnormality resolves following 
statin dose reduction or statin discontinuation 
x Patients with elevated creatinine kinase caused by a myocardial infarction 
In addition, discontinuation caused by a laboratory abnormality can be either permanent or 
temporary, depending on the particular case. There is no requirement for permanent treatment 
discontinuation in every case of the general guidance for the follow-up of selected laboratory 
abnormalities mentioned in Appendix C. 
10.5 
OBLIGATIONS OF THE SPONSOR 
During the course of the study, the Sponsor will report in an expedited manner: 
x 
All SAEs that are both unexpected and at least reasonably related to the IMP (SUSAR), to 
the regulatory authorities, IECs/IRBs as appropriate and to the Investigators. 
x 
All SAEs that are expected and at least reasonably related to the IMPs to the regulatory 
authorities, according to local regulations. 
The AESIs listed in Section 10.4.1.3 will be reported to those regulatory authorities who require 
such reporting.  
In this study, some AEs are considered related to the underlying condition and thus will not be 
considered unexpected as indicated in the Investigator’s Brochure. 
Any other AE not listed as an expected event in the Investigator’s Brochure or in this protocol 
will be considered unexpected. 
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 are given in Section 10.4.1.4 and on 
reporting these reactions is given in Appendix B. 
10.6.2 Allergic adverse events 
Specific e-CRF screens are to be filled in to assess allergic reactions or allergic-like reactions that 
may occur during the clinical studies conducted with alirocumab.

Page 72 
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 Reaction and/or 
Local Injection Site Reaction Complementary Form. 
Adverse events that are obviously not of allergic origin (eg, local injection site reactions 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 E 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 10.3.2 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 should be obtained. An additional blood sample will have to be drawn for PK and 
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 
reactions) 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. General Allergic Reaction 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.

11.2 
DISPOSITION OF PATIENTS 
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 double-blind treatment kit number 
allocated and recorded in the IVRS/IWRS database, regardless of whether the treatment kit was 
used or not. 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. The safety experience of patients treated and not randomized will be reported 
separately and these patients will not be in the safety population. 
For any patient randomized more than once, only the data associated with the first randomization 
will be used in any analysis population. The safety experience associated with any later 
randomization will be assessed separately. 
11.3 
ANALYSIS POPULATIONS 
11.3.1 Efficacy populations 
The primary efficacy analysis population will be the ITT population as defined below.

11.3.1.1 Intent–to-treat population 
The ITT population is defined as all randomized patients who have an evaluable primary efficacy 
endpoint.  
Patients in the ITT population will be analyzed according to the treatment group allocated by 
randomization. 
The primary efficacy endpoint is evaluable when the two following conditions are met: 
x The baseline calculated LDL-C value is available 
x A least one calculated LDL-C value is available within one of the analysis windows up to 
Week 24. 
11.3.1.2 Modified intent-to-treat population 
The modified ITT (mITT) population (otherwise referred to as the on-treatment population) is 
defined as all randomized patients who took at least one dose or part of a dose of the double-blind 
IMP and have an evaluable primary efficacy endpoint during the efficacy treatment period. 
Patients in the mITT population will be analyzed according to the treatment group allocated by 
randomization. 
The primary efficacy endpoint is considered as evaluable when the two following conditions are 
met: 
x The baseline calculated LDL-C value is available 
x At least one calculated LDL-C value is available during the efficacy treatment period and 
within one of the analysis windows up to Week 24. 
The efficacy treatment period is defined as the time period from the first double-blind IMP 
injection up to 21 days after the last double-blind IMP injection. 
11.3.2 Safety population 
The safety population considered for safety analyses will be the randomized population who did 
actually receive at least one dose or part of a dose of the double-blind IMP. Patients will be 
analyzed according to the treatment actually received (placebo or alirocumab). 
The safety analysis will focus on the Treatment Emergent Adverse Events (TEAE) period defined 
as the time from the first double-blind dose to the last double-blind dose of IMP + 70 days 
(10 weeks). 
In addition:  
x 
Nonrandomized but treated patients will not be part of the safety population, but their 
safety data will be presented separately.

For patients receiving more than 1 study treatment during the trial, the treatment group 
allocation for as-treated analysis will be the one to which the patient was treated with the 
longest duration  
11.3.3 Other analysis population  
The anti-alirocumab antibody analysis will be performed on all treated patients (safety population) 
with a blood sample at Week 0 (baseline) and at least one evaluable blood sample for antibodies 
post-double-blind IMP injection.

STATISTICAL METHODS 
Separate analyses will be performed for Type 1 diabetes patients on one hand and Type 2 diabetes 
patients on the other hand. However, some endpoints may also be analyzed on the pooled data 
(Type 1 and Type 2 diabetes patients together). These analyses will be defined later in the 
statistical analysis plan. 
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 treatment received within the safety population. 
In order to ensure the continuity of the investigational treatment for the patients without 
interruption (only in case a disruption occurs in the availability of device components or during 
production of the prefilled pen), back-up plans may be implemented as described in Section 8.1. 
In that case, exposure to initial device and back-up device will be summarized and impact on 
study results will be assessed. More details will be provided in the SAP, if applicable. 
11.4.1.1 Extent of investigational medicinal product exposure 
The total exposure will be assessed by: 
x 
Duration of IMP exposure in weeks is defined as:  (last dose of double-blind IMP injection 
date – first dose of double-blind IMP injection date + 14 days)/7, regardless of unplanned 
intermittent discontinuations.  
x 
The total number of injections by patient. 
The number (n) and percentage (%) of patients with an up-titration in the alirocumab group will 
be described.

11.4.1.2 Compliance  
A given administration will be considered noncompliant if the patient did not take the planned 
dose of treatment as required by the protocol. No imputation will be made for patients with 
missing or incomplete data.  
Compliance will be assessed using the following parameters: 
x 
The injection frequency will be defined for each patient as the average number of days 
between 2 injections, that is: (last dose date – first dose date)/(number of injections -1). 
This parameter will be summarized descriptively (N, Mean, SD, Median, Min and Max). 
11.4.2 Analyses of efficacy endpoints 
11.4.2.1 Analysis of primary efficacy endpoint(s) 
The percent change in calculated LDL-C from baseline to Week 24 as defined in Section 9.1.1 
will be analyzed in the ITT population using a mixed effect model with repeated measures 
(MMRM) approach. All post-baseline data available within Week 8 to Week 24 analysis windows 
will be used and missing data are accounted for by the MMRM model.  
The model will include the fixed categorical effects of treatment group (placebo versus 
alirocumab), time point (Week 8, Week 12, Week 20 and Week 24), treatment-by-time point 
interaction, as well as the continuous fixed covariates of baseline LDL-C value and baseline 
value-by-time point interaction. Model assumptions for normality will be explored prior to the 
analysis testing. 
This model will be run using SAS Mixed procedure with an unstructured correlation matrix to 
model the within-patient errors. Parameters will be estimated using restricted maximum likelihood 
method with the Newton-Raphson algorithm. Denominator degrees of freedom will be estimated 
using Satterthwaite’s approximation. This model will provide baseline adjusted LS means 
estimates at Week 24 for both treatment groups with their corresponding standard errors (SEs) and 
95% confidence intervals (CIs). To compare the alirocumab group to the placebo group, an 
appropriate contrast statement will be used to test the differences of these estimates, at the 2-sided 
0.05 level. Separate analyses will be performed for Type 1 diabetes patients on one hand (alpha 
risk = 0.05) and Type 2 diabetes patients on the other hand (alpha risk = 0.05). 
Let μ0 and μ1 be the population means of the percent change from baseline in calculated LDL-C 
at Week 24 under placebo and alirocumab, respectively. The null hypothesis that will be tested is: 
 
H0 : μ0 = μ1 
versus 
H1 : μ0  μ1 
Robustness of this statistical method will be assessed via sensitivity analyses detailed in the SAP, 
including different methodologies for missing data (multiple imputation and potentially pattern

mixture modeling). In addition, sensitivity analysis will be conducted using measured LDL-C to 
evaluate the robustness of the results regardless of the way to assess LDL-C. Correlation of 
calculated LDL-C with measured LDL-C will be explored graphically as deemed necessary. 
11.4.2.2 Analyses of secondary efficacy endpoints 
Method for controlling the overall type-I error rate when testing the key secondary efficacy 
endpoints is described in Section 11.4.2.3.  
For key secondary efficacy endpoints (defined in Section 9.2.1) and other efficacy endpoints 
(described in Section 9.2.3), descriptive summaries and analyses will be performed in the ITT 
population or mITT population depending on the estimand used.  
For descriptive summaries, percent change from baseline in calculated LDL C, C, HDL-C, TG, 
and non-HDL-C will be provided at each time point for each treatment group. All measurements, 
scheduled or unscheduled will be assigned to analysis windows defined in the SAP in order to 
provide an assessment for these time points. Laboratory assessments other than the ones provided 
by the central laboratory will be excluded. The time profile of each parameter will be plotted by 
treatment group with the corresponding SEs.  
Similar tables (with either percent change from baseline or absolute change from baseline for the 
ratio) and plots will be provided for other efficacy endpoints: Apo B, Apo A-1, ratio 
Apo B/Apo A-1, Apo C-III, Lp(a), TGRL, LDL-C particle size, and LDL-C particle number. For 
TG and Lp(a), summary statistics will include Q1 and Q3, and medians (instead of means) by 
time point will be plotted.  
Multiple types of measurements are planned to be analyzed during differing time points in the 
trial, specifically continuous measurements expected to have a normal distribution (eg, percent 
change in calculated LDL-C), continuous measurements expected to have a non-normal 
distribution (eg, TG), and binary measurements (eg, proportion of patients reaching LDL-C 
<70 mg/dL). 
Continuous endpoints anticipated to have a normal distribution 
Continuous secondary variables defined in Section 9.2 anticipated to have a normal distribution 
(eg, lipids other than TG and Lp[a]) will be analyzed using the same MMRM model as for the 
primary endpoint. Specifically, the model will contain fixed categorical effects of treatment 
group, planned time points to Week 24 and treatment-by-time point interaction, as well as, the 
continuous fixed covariates of corresponding baseline value and baseline value-by-time point 
interaction. 
Continuous endpoints anticipated to have a non-normal distribution 
Continuous secondary efficacy endpoints defined in Section 9.2, anticipated to have a nonnormal 
distribution (ie, TG and Lp[a]), will be analyzed using a robust regression model (ie, 
ROBUSTREG SAS procedure with M-estimation option) with treatment group as main effect and 
corresponding baseline value(s) as covariate. Missing values will be addressed using a multiple

imputation approach, which will be described in the SAP. The variables in the multiple imputation 
model will at least include the same variables as used in the robust regression model. The 
treatment group combined means will be provided with respective SE estimates. The combined 
mean difference between the treatment groups will be provided with the SE, 95% CI and p-value. 
Binary endpoints 
Binary secondary efficacy endpoints defined in Section 9.2 will be analyzed using logistic 
regression with treatment group as main effect and corresponding baseline value(s) as covariate. 
Missing values will be addressed using a multiple imputation approach which will be described in 
the SAP. The variables in the multiple imputation model will at least include the same variables as 
used in the logistic regression model. Treatment effects will be compared and the combined odds 
ratio estimate between the treatment groups, with their corresponding 95% CIs and p-value will 
be provided.  
In the data dependent case that the logistic regression method is not applicable (eg, the response 
rate is zero in 1 treatment arm and thus the maximum likelihood estimate may not exist), the Last 
Observation Carried Forward (LOCF) approach would be used for handling of missing values and 
an exact conditional logistic regression would be performed to compare treatment effects. The 
LOCF imputation method will consist of using the last value obtained up to the Week 24 analysis 
window (or Week 12 as applicable) to impute the missing week 24 value (or Week 12 
respectively). 
11.4.2.3 Multiplicity considerations 
In order to handle multiple key secondary efficacy endpoints, the overall type-I error will be 
controlled by the use of a sequential inferential approach. Statistical significance of the primary 
parameter at the 0.05 alpha level is required before drawing inferential conclusions about first key 
secondary parameter (refer to order of list in Section 9.2.1).  
Inferential conclusions about successive key secondary parameters require statistical significance 
of the prior one. This fixed hierarchical approach will ensure a strong control of the overall type-I 
error rate at the 0.05 level.  
No further adjustments will be made for other efficacy endpoints for which p-values will be 
provided for descriptive purpose only. 
11.4.3 Analyses of safety data 
The summary of safety results will be presented by treatment group. No formal inferential testing 
will be performed. Summaries will be descriptive in nature. 
All safety analyses will be performed on the Safety population using the following common rules: 
x The baseline value is defined generally as the last available value before the first injection 
of double-blind IMP.

The following definitions will be applied to laboratory parameters and vital signs. 
x 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. 
x PCSA criteria will determine which patients had at least 1 PCSA during the on-treatment 
period, taking into account all evaluations performed during the on-treatment period, 
including unscheduled or repeated evaluations.  The number of all such patients will be the 
numerator for the on-treatment PCSA percentage. 
x Treatment period: the treatment period used for quantitative analysis is defined as the time 
from first dose of double-blind IMP injection to the last dose of double-blind IMP 
injection + 21 days 
The following definitions will be applied to AEs 
x Pre-treatment AEs are AEs that developed or worsened or became serious during the 
pre-treatment period 
x TEAEs are AEs that developed or worsened or became serious during the TEAE period 
x Post-treatment AEs are AEs that developed or worsened or became serious during the 
post-treatment period 
Liver function tests 
The liver function tests, namely ALT, AST, alkaline phosphatase and total bilirubin, are used to 
assess possible drug induced liver toxicity. The proportion of patients with PCSA values at any 
postbaseline visit by baseline status will be displayed by treatment group for each parameter.  
A graph of distribution of peak values of ALT versus peak values of total bilirubin will also be 
presented. Note that the ALT and total bilirubin values are 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. 
The incidence of liver-related AEs will be summarized by treatment group. The selection of 
preferred terms will be based on standardized MedDRA query (SMQ) Hepatic disorder. Time to 
liver-related treatment discontinuation and time to liver death may also be provided based on 
hepatic disorder SMQ. 
11.4.3.1 Adverse events 
Adverse event incidence tables will present 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 for each treatment group, the number (n) and percentage 
(%) of patients experiencing an AE. 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 treatment group.

Adverse event incidence table will be provided by treatment group 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. 
If any clinically significant signal is detected and needs further characterization or for AE of 
clinical interest, exploration of time to onset will be performed for these selected TEAEs as 
described below to account for the differential exposure time in all patients.  
Selected TEAEs will be also analyzed using time-to-event approach (Kaplan-Meier 
methodology). Time from the first dose of double-blind IMP injection to the first occurrence of 
the event will be calculated (only the first event will be counted). Patients without any event will 
be censored at the end of the TEAE period. Incidence rates at 6 months of exposure will be 
presented and Kaplan-Meier curves will be provided. 
Death: The following deaths summaries will be generated: 
x 
Number (%) of patients who died by study period (TEAE, on-study, post-study) 
summarized on the safety population by treatment received 
x 
Death in non-randomized patients or randomized and not treated patients   
x TEAE leading to death (death as an outcome on the AE 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. 
11.4.3.2 Laboratory data and vital signs 
The summary statistics (including mean, median, Q1, Q3, SE, minimum and maximum) of all 
laboratory variables, all vital signs parameters (raw data and changes from baseline) will be 
calculated for each visit, last and worst value assessed during the treatment period and presented 
by treatment group. 
For selected parameters, mean changes from baseline with the corresponding SE will be plotted 
over time (at same time points) in each treatment group. 
The incidence of PCSAs at any time during the TEAE period (on-treatment PCSAs) will be 
summarized by treatment group whatever the baseline level and/or according to the following 
baseline categories: 
x 
Normal/missing 
x 
Abnormal according to PCSA criterion or criteria 
For laboratory parameters for which PCSA criterion is not defined, similar table(s) using the 
normal range could be provided.

INTERIM ANALYSIS 
If needed for the purpose of scientific communication, both the efficacy and safety analyses will 
be performed at the Week 24 cut-off date and an update of the safety analysis at the end of the 
study, a two-step analysis as described below. All the efficacy data will be available for final 
analysis at a cut-off date corresponding to the Week 24 visit of the last patient. Since safety data 
are collected until the end of the study (Week 32), if the analysis with Week 24 data is performed, 
an update of the safety analysis will be performed at the end of the study. If analyses are not 
needed at Week 24, then there will be only a one time analysis at the end of the study. 
The first-step analysis will be conducted as soon as all patients have been randomized and have at 
least all their data up to Week 24 collected and validated, and will consist of a final analysis of the

primary and secondary efficacy endpoints up to Week 24. The safety analysis will be performed 
on all safety data collected and validated at the time of this first-step analysis.  
The second-step analysis will consist of the updated analysis of safety endpoints until Week 32. 
Even in the case of a two-step analysis, there is no multiplicity issue because all efficacy analyses 
will be completed at the time of the advanced analysis.  
Selected individuals who are not involved in the conduct of the study after the first step analysis 
will perform the second step analysis; individual patient identification will not be released to 
anyone who is directly involved in the conduct of the study. The second step analysis process, the 
measures used to protect the blind and the integrity of the study, as well as a communication plan

OVERVIEW AND INVESTIGATIONAL PLAN   
1.1 
STUDY DESIGN AND RANDOMIZATION 
This is a Phase 3b, multinational, multicenter, randomized, double-blind, placebo-controlled, 
parallel group, unbalanced (2:1 ratio) and stratified study. 
After a screening phase of up to three weeks, patients will be centrally randomized via interactive 
voice response system (IVRS) or interactive web response system (IWRS) to one of the two 
treatment groups (alirocumab:placebo) and will be treated in a double-blind manner for 
approximately 24 weeks. Randomization ratio will be 2:1 (alirocumab:placebo) and patients will 
be stratified by diabetes type (ie, Type 1 diabetes versus Type 2 diabetes). 
Approximately 500 patients will be randomized (333 in the alirocumab group and 167 in the 
placebo group). The recruitment of patients with Type 2 diabetes will complete when 
approximately 400 patients have been randomized. Recruitment of patients with Type 1 diabetes 
will continue until approximately 100 patients have been randomized or the end of the targeted 
recruitment period (summer 2016), whichever comes first. 
1.2 
OBJECTIVES 
1.2.1 Primary objectives 
The primary objectives of this study are:  
x
To demonstrate the superiority of alirocumab in comparison with placebo in the reduction
of calculated low-density lipoprotein cholesterol (LDL-C) after 24 weeks of treatment in
patients with diabetes treated with insulin and with hypercholesterolemia at high
cardiovascular (CV) risk not adequately controlled on maximally tolerated LDL-C
lowering therapy;
x
To evaluate the safety and tolerability of alirocumab in patients with diabetes treated with
insulin.
1.2.2 Secondary objectives 
The secondary objective of this study is:  
x
To demonstrate that alirocumab is superior in comparison to placebo in its effects on other
lipid parameters at Weeks 12 and 24:
-
measured LDL-C;
-
non-high-density lipoprotein cholesterol (non-HDL-C);
-
apolipoprotein B (Apo B);
-
total cholesterol (TC);

1.2.3 Other objectives 
The other objectives of this study are:  
x 
 
x To evaluate the development of anti-alirocumab antibodies (ADA); 
x To describe the evolution of diabetes-related endpoints (glycated hemoglobin A1c 
[HbA1c], fasting plasma glucose [FPG], total daily insulin dose, daily insulin dose per kg, 
number of glucose lowering treatments). 
While these objectives are not specified in the study protocol, they nevertheless represent 
additional clinically relevant objectives of the study that will be explored.

1.4 
STUDY PLAN 
This is a Phase 3b study to assess the efficacy and safety of alirocumab administered by 
subcutaneous injection in insulin treated patients with Type 1 or Type 2 diabetes and with 
hypercholesterolemia at high CV risk not adequately controlled on maximally tolerated LDL-C 
lowering therapy. 
The study consists of a screening period of up to 3 weeks, a double-blind treatment period of 
24 weeks, and a safety observation period of 8 weeks. 
Patients, unless they are statin intolerant, will be taking a stable, maximally tolerated dose of 
statin therapy with or without other lipid modifying therapies (LMT). Statin dose and dose 
regimen as well as dose and dose regimen of other LMT(s) (if applicable) should be stable 
throughout the entire study duration including for 4 weeks prior to the screening period, during 
the screening period, and from screening to randomization until the Week 24 visit. Patients should 
be on a stable diet for glucose and lipid management throughout the entire study duration from 
screening to the Week 24 visit. Patients should be receiving treatment for diabetes in accordance 
with local/regional standards of care. Concomitant medications, including glucose lowering 
treatments, should be kept to a minimum during the study, however, if considered necessary for 
the patient’s welfare they may be given at the discretion of the Investigator, with a stable dose 
(when possible). 
Alirocumab will be administered subcutaneously with a starting dose of 75 mg every 2 weeks 
(Q2W) for 12 weeks with a blinded up-titration to alirocumab 150 mg Q2W at Week 12 if the 
LDL-C at the Week 8 visit is 70 mg/dL (1.81 mmol/L). Patients who have an LDL-C <70 mg/dL 
(1.81 mmol/L) at the Week 8 visit will continue with alirocumab 75 mg Q2W until the end of the 
treatment period. 
The data on lipid parameters from blood samples will be masked after randomization. No attempts 
should be made by the Investigator or patient to have the patient’s lipid values independently 
evaluated after randomization until after the Week 24 visit, except for the safety of the patient, as 
per the Investigator’s judgment. 
Patients will visit the study site at Weeks -3, 0, 8, 12, 20, and 24 with lab work at each visit; in 
addition a phone visit is scheduled at Weeks 4 and 32.

MODIFICATIONS TO THE STATISTICAL SECTION OF THE PROTOCOL 
Definition of screened patients 
In protocol section 11.2, screened patients are defined as any patient who met the inclusion 
criteria and signed the informed consent. In SAP version 4.0 and above, definition of screened 
patients was updated to any patients who signed the informed consent only. 
Definition of an additional compliance parameter 
The overall compliance was added in assessment of extent of investigational medicinal product 
exposure and compliance. 
Additional effects added to the analysis model of the primary efficacy endpoint 
Additional effects were added to the analysis model of the primary efficacy endpoint initially 
defined in protocol section 11.4.2.1: the strata (ie, diabetes type), the strata-by-time point 
interaction, and the treatment-by-strata-by-time point interaction.

STATISTICAL AND ANALYTICAL PROCEDURES 
2.1 
ANALYSIS ENDPOINTS 
The baseline value is defined as the last available value obtained prior to the first double-blind 
investigational medicinal product (IMP) injection, including values obtained at the day of 
randomization since all blood samples for laboratory assessment taken on this day are performed 
prior to the first IMP injection. For patients randomized and not treated, the baseline value is 
defined as the last available value obtained up to the date and time of randomization. 
 
2.1.1 Demographic and baseline characteristics

2.1.3 Efficacy endpoints 
Efficacy parameters include lipid parameters (ie, calculated LDL-C, measured LDL-C, non-HDL-
C, Apo B, TC, Lp(a), TG, HDL-C, TGRL, LDL particle size and number, Apo A-1, Apo C-III, 
ratio Apo B/Apo A-1, TC/HDL-C). All these parameters are measured or calculated by a Central 
Laboratory, for both scheduled and unscheduled time points. Calculated LDL-C is obtained using 
the Friedewald formula (2). Non-HDL-C is calculated by subtracting HDL-C from the TC. 
Measured LDL-C is obtained via beta quantification method. All measured LDL-C values 
provided by the Central Laboratory including those done in case of TG values exceeding 400 
mg/dL (4.52 mmol/L) will not be used for the analysis of calculated LDL-C endpoints. TGRL will 
be calculated by total cholesterol minus HDL cholesterol minus measured LDL cholesterol. In 
cases where the measured LDL-C is missing and the calculated LDL-C is non-missing, the 
calculated LDL-C will be used for the computation of TGRL. Both fasting and non-fasting 
measurements will be used for calculation of TGRL. 
Unless otherwise specified, all lipid values (scheduled or unscheduled, fasting or not fasting) may 
be used to provide a value for the primary and secondary efficacy endpoints. 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 8 to Week 24 time points. For TG, only 
fasting measurements will be used. Measurements with missing fasting status will be excluded 
from the analyses. 
2.1.3.1 Primary efficacy endpoint(s) 
The primary efficacy endpoint is the percent change in calculated LDL-C from baseline to Week 
24 in the intent-to-treat (ITT) population. Primary endpoint is defined as: 100 x (calculated LDL-
C value at Week 24 - calculated LDL-C value at baseline) / calculated LDL-C value at baseline.  
2.1.3.2 Secondary efficacy endpoint(s) 
2.1.3.2.1 Key secondary efficacy endpoints 
The key secondary endpoints are: 
x Percent change in calculated LDL-C from baseline to Week 24, using all calculated LDL-
C values during the efficacy treatment period (see Section 2.1.4, on-treatment estimand); 
x Percent change in measured LDL-C from baseline to Week 24 (ITT estimand); 
x Percent change in calculated LDL-C from baseline to Week 12 (ITT estimand); 
x Percent change in measured LDL-C from baseline to Weeks 12 (ITT estimand);

2.1.4 Safety endpoints 
The safety analysis will be based on the reported AEs and other safety information, such as 
clinical laboratory data and vital signs. 
Observation period 
The observation period will be divided into 3 periods: 
x Pre-treatment period is defined from the signed informed consent up to the first dose of 
double-blind IMP injection. 
x Treatment Emergent Adverse Event (TEAE) period is defined as the time from the first 
dose of double-blind IMP injection to the last dose of IMP injection + 70 days (10 weeks) 
as residual effect of treatment is expected until 10 weeks after the stop of double-blind 
IMP. As the hour of IMP injection is not collected, the time of double blind IMP injection 
refers, here and in the rest of the document, to the date of double-blind IMP injection. 
The TEAE period will include: 
- 
The efficacy treatment period defined as the time from the first dose of double-blind 
IMP injection up to the day of last dose of double-blind IMP injection + 21 days, as 
serum concentration of alirocumab >10 μg/mL is expected for approximately 21 days 
following administration of 150 mg, and because throughout the previous studies it 
was observed that when alirocumab concentrations declined below this concentration, 
decrease in effect on LDL-C is observed. 
- 
The residual efficacy treatment defined as the time from the day of last dose of double-
blind IMP injection + 22 days up to the day of last dose of double-blind IMP injection 
+ 70 days (10 weeks). 
x Post-treatment period is defined as the time starting the day after the end of the TEAE 
period up to resolution/stabilization of all serious adverse events (SAE) and AEs of special 
interest (AESI), whichever comes last. 
The on-study observation period is defined as the time from the day of the first dose of double-
blind IMP injection until the last protocol planned visit of the patient (Week 32 phone call).

2.1.4.1 Adverse events variables 
Adverse events (including SAEs, AESI and product complaints) are recorded from the time of 
signed informed consent to the end of the study. All AEs diagnosed by the Investigator will be 
reported and described. 
All AEs will be coded to a “Lowest Level Term (LLT)”, “Preferred Term (PT)”, “High Level 
Term (HLT)”, “High Level Group Term (HLGT)”, and associated primary “System Organ Class 
(SOC)” using the version of MedDRA currently in effect at Sanofi at the time of database lock. 
Adverse event observation period 
x Pre-treatment AEs are AEs that developed or worsened or became serious during the pre-
treatment period. 
x Treatment-emergent AEs are AEs that developed or worsened or became serious during 
the TEAE period. 
x Post-treatment AEs are AEs that developed or worsened or became serious during the 
post-treatment period. 
Adverse events of special interest 
An AESI is an AE (serious or non-serious) that needs to be monitored, documented, and managed 
in a pre-specified manner described in the protocol. 
For this study, the AESI are:  
x Increase in alanine aminotransferase (ALT):  
- 
ALT 3 times the upper limit of normal range (ULN) (if baseline ALT <ULN) or ALT 
2 times the baseline value (if baseline ALT ULN), selected using central laboratory 
data; 
x Allergic drug reactions: 
- 
 requiring consultation with another physician and selected using standardized 
MedDRA query (SMQ) “hypersensitivity” (broad and narrow) excluding the following 
PTs linked to local injection site reactions (“injection (infusion) site dermatitis”, 
“injection (infusion) site hypersensitivity”, “injection (infusion) site oedema”, 
“injection (infusion) site rash”, “injection (infusion) site urticaria”, “injection 
(infusion) site eczema”,  “injection (infusion) site vasculitis”, “injection (infusion) site 
swelling”);  
- 
An additional analysis will be performed for any general allergic event not meeting 
AESI criteria (not requiring consultation with another physician) but meeting the 
above SMQ criteria. 
x Local injection site reactions  
- 
deemed to be allergic by the Investigator (or have an allergic component) AND that 
require consultation with another physician AND related to IMP (as opposed to 
another injectable) AND selected using the following selection of PT from the safety 
complementary form for local injection site reaction or from the reported term

injectable). 
x Pregnancy of female patient (including male patient’s partner) selected using appropriate 
MedDRA codes. 
x Symptomatic overdose with IMP; 
- 
An overdose with IMP is defined as at least twice of the intended dose within the 
intended therapeutic interval (ie, 2 or more injections are administered in <7 calendar 
days), to be reported using the Term “symptomatic OVERDOSE” (accidental or 
intentional), indicating the circumstance in parentheses (eg, “symptomatic overdose 
[accidental]” or “symptomatic overdose [intentional]”).   These events will be selected 
using the AESI category as selected by the site.   
- 
An additional analysis of overdoses AE will be performed: analysis of all overdose 
cases (whether symptomatic or asymptomatic) related to IMP using the HLT for 
overdose. 
x Neurologic events  
- 
requiring additional exams/procedures or consultation selected using SMQ 
“demyelination” (broad and narrow), “peripheral neuropathy” (broad and narrow), and 
“Guillain Barre syndrome” (broad and narrow) excluding the following PTs “acute 
respiratory distress syndrome”, “asthenia”, “respiratory arrest”, and “respiratory 
failure”. 
- 
An additional analysis will be performed analyzing all events meeting the above SMQ 
criteria for neurologic events whether or not the criteria for an AESI are met (whether 
or not requiring additional exams/procedures or consultation).

2.1.9 Diabetes related endpoints 
The analyses of diabetes-related endpoints will include the following parameters: 
x HbA1c, in % and in mmol/mol. 
x FPG  
x Total daily insulin dose and daily insulin dose per kg.  
The total daily insulin dose by patient and visit will be computed as the mean of the daily 
insulin dose in the last 7 days prior to visit, taken from the insulin log form. The daily 
insulin dose per kg will be computed from this total daily insulin dose and the weight at 
each visit. Total daily insulin dose and daily insulin dose per kg will be summarized

broken down into basal and prandial daily dose according to fixed basal and prandial 
percentages. 
x Number of glucose lowering treatments:  
- 
For non-insulin treatments each unique treatment will be counted as 1, whereas for 
insulin treatments, insulin will be counted as 1 in total even if the patient is taking 
more than one treatment (for example, a patient on glargine monotherapy will have “1” 
glucose lowering treatment, and a patient on glargine and humalog without additional 
glucose lowering treatments will also have “1” glucose lowering treatment).  
- 
For combinations of insulin and non-insulin treatment, the insulin will be counted as 1  
and each non-insulin in the combination will be counted as 1 (for example, ideglira 
would count as “1” for the insulin degludec and “1” for the liraglutide, ie, a total of “2” 
glucose lowering treatments).

2.2 
DISPOSITION OF PATIENTS 
This section describes patient disposition for both patient study status and the patient analysis 
populations. 
Screened patients are defined as any patients who signed the informed consent. 
Randomized patients consist of all screened patients, with a double-blind treatment kit number 
allocated and recorded in the IVRS/IWRS database, regardless of whether the treatment kit was 
used or not. 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. The safety experience of patients treated and not randomized will be reported 
separately and these patients will not be in the safety population. 
For any patient randomized more than once, only the data associated with the first randomization 
will be used in any analysis population. The safety experience associated with any later 
randomization will be assessed separately. 
For patient study status, the total number of patients in each of the following categories will be 
presented by type of diabetes and in the pooled data in the clinical study report using a flowchart 
diagram or summary table: 
x Screened patients; 
x Screen failure patients and reasons for screen failure (inclusion/exclusion criteria); 
x Non-randomized but treated patients; 
x Randomized patients; 
x Randomized but not treated patients and reason for not treated (from reasons on end of 
study CRF form); 
x Randomized and treated patients; 
x Patients who completed the study treatment period as per protocol; 
x Patients who discontinued the study treatment and main reason for permanent treatment 
discontinuation; 
x Patients who completed the study period as per protocol; 
x Patients who discontinued the study and main reason for study discontinuation; 
x Status at last study contact. 
For all categories of patients (except for the screened and non-randomized categories) percentages 
will be calculated using the number of randomized patients as the denominator.

Reasons for discontinuation will be supplied in tables giving numbers and percentages by 
treatment group. A listing of patients who prematurely discontinued study treatment with further 
reason provided in free text will be provided. 
The incidence of premature treatment discontinuation (irrespective of the reason) and premature 
treatment discontinuation due to AEs will be presented graphically by treatment group on 
randomized and treated patients (as randomized), using Kaplan-Meier method. 
The incidence of premature study discontinuation (irrespective of the reason) and premature study 
discontinuation due to AEs will be presented graphically by treatment group on randomized and 
treated patients (as randomized), using Kaplan-Meier method. 
Patients with insufficient post-treatment follow-up will be described on the safety population by 
treatment group. A patient is considered with insufficient post-treatment follow-up or without 
post-treatment follow-up at the end of the study in the following cases: 
x If the patient is not assessed at the post-treatment follow-up call or any post-treatment 
visit, unless patient died before, or 
x If the last post-treatment visit is less than 9 weeks after the last double-blind injection. 
All major deviations potentially impacting efficacy 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. Patients excluded from the ITT/mITT 
population will be listed as well as patients with major deviations potentially impacting efficacy 
analyses not resulting in exclusion from ITT/mITT population. These deviations are listed in the 
data review and surveillance plan. 
Additionally, the following analysis populations will be summarized by treatment group: 
x Randomized population; 
x Efficacy population: ITT population and mITT; 
x Safety population; 
x 
 
x ADA population. 
Definitions of the study populations are provided in Section 2.3. 
2.2.1 Randomization and drug dispensing irregularities 
Randomization and drug-dispensing irregularities occur whenever: 
1. A randomization is not in accordance with the protocol-defined randomization method, 
such as a) an ineligible patient is randomized, b) a patient is randomized based on an 
incorrect stratum, c) a patient is randomized twice. 
OR 
2. A patient is dispensed an IMP kit not allocated by the protocol-defined randomization, 
such as a) a patient at any time in the study is dispensed a different treatment kit than as

randomized (which may or may not contain the correct-as-randomized IMP), or b) a 
nonrandomized patient is treated with IMP reserved for randomized patients. 
Randomization and drug-dispensing irregularities will be monitored throughout the study and 
reviewed on an ongoing basis. Randomization and drug-dispensing irregularities to be 
prospectively identified include but are not limited to:  
 
Randomization and drug allocation irregularities 
Kit dispensation without IVRS transaction 
Erroneous kit dispensation 
Kit not available 
Randomization by error 
Patient randomized twice 
Stratification error 
A kit allocated at Day 1 or any unscheduled replacement before Week 12 
is administered to the patient after his up-titration visit (Week 12) 
Kit dispensation without IVRS transaction 
All randomization and drug-dispensing irregularities will be documented in the clinical study 
report. If the number of irregularities is large enough to make a tabular summary useful, the 
irregularities will be categorized and summarized among randomized patients (number and 
percentages). Nonrandomized, treated patients will be described separately. A listing of 
randomization and drug allocation irregularities as well as a listing of patients randomized twice 
(or more) or treated but not randomized will be produced. 
A listing of patients with treatment group as randomized different than treatment group as treated 
will be produced. 
2.3 
ANALYSIS POPULATIONS 
Patients treated without or before being randomized will not be considered randomized and will 
not be included in any analysis population. The safety experience of these patients will be 
reported separately. 
Randomized population includes all randomized patients as defined in Section 2.2. 
2.3.1 Efficacy populations 
The primary efficacy analysis population will be the ITT population.

2.3.1.1 Intent–to-treat population 
The ITT population is defined as all randomized patients who have an evaluable primary efficacy 
endpoint defined as: 
x Baseline calculated LDL-C value available; 
x At least one calculated LDL-C value available within one of the analysis windows up to 
Week 24. 
Patients in the ITT population will be analyzed according to the treatment group allocated by 
randomization (ie, as-randomized group). 
This population will be used to assess the ITT estimands. 
2.3.1.2 Modified-intent–to-treat population 
The mITT population (otherwise referred to as the on-treatment population) is a subset of the ITT 
population defined as all randomized patients who took at least one dose or part of a dose of the 
double-blind IMP and have an evaluable primary efficacy endpoint during treatment period 
ie, Baseline calculated LDL-C value available; 
x At least one calculated LDL-C value available during the efficacy treatment period and 
within one of the analysis windows up to Week 24. 
The efficacy treatment period is defined as the time period from the first double-blind IMP 
injection up to 21 days after the last double-blind IMP injection. 
Patients in the mITT population will be analyzed according to the treatment group allocated by 
randomization (ie, as-randomized group). 
This population will be the basis for the on-treatment estimand evaluations. 
2.3.2 Safety population 
The safety population considered for safety analyses will be the randomized population who did 
actually receive at least one dose or part of a dose of the double-blind IMP. 
Patients will be analyzed according to the treatment actually received. 
The safety analysis will focus on the TEAE period defined as the time from the first double-blind 
dose to the last double-blind dose of IMP + 70 days (10 weeks). 
In addition: 
x Nonrandomized but treated patients or patients treated with the double-blind IMP before 
the randomization will not be part of the safety population, but their safety data will be 
presented separately;

be included in the safety population as randomized; 
x For patients receiving more than 1 study treatment during the trial, the treatment group 
allocation for as-treated analysis will be the one to which the patient was treated with the 
longest duration. 
2.3.3 Anti-alirocumab antibody population

STATISTICAL METHODS 
2.4.1 Demographics and baseline characteristics 
Parameters described in Section 2.1.1 will be summarized by treatment group and overall, by 
diabetes type and on the pooled data, using descriptive statistics. 
Continuous data will be summarized using the number of available data, mean, SD, median, Q1, 
Q3, minimum, and maximum for each treatment group. For lipid efficacy parameters, summary 
statistics will include Q1 and Q3 and medians. Categorical and ordinal data will be summarized 
using the number and percentage of patients in each treatment group. 
Parameters will be summarized on the randomized population analyzed in the treatment group to 
which they were randomized. In the randomized population, parameters will also be summarized 
within each randomization stratum as per IVRS/IWRS. Similar analyses will be done on the ITT 
population in the as-randomized treatment group (respectively safety population in the as-treated 
treatment group) if the size of the sub-population is different [>10%] from the size of the 
randomized population in any treatment group and will be included in the appendices. 
All reported patient’s medical and surgical history will be presented by primary SOC and HLT. 
The tables will be sorted by SOC internationally agreed order and decreasing frequency of HLT 
based on the overall incidence across treatment groups.

2.4.3 Prior, concomitant or post-treatment medications 
The prior, concomitant and post-treatment medications will be presented for the safety population 
by category (all drugs, LMT). For CV drugs, the concomitant medications will be presented. 
Medications will be summarized by treatment group according to the WHO-DD dictionary, 
considering the first digit of the anatomic therapeutic chemical (ATC) category class (anatomic 
category) 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 all prior medications will be sorted by decreasing frequency of ATCs based on the 
overall incidence across treatment groups. In case of equal frequency, alphabetical order will be 
used.

Week 12 and Week 24. 
The number of glucose lowering treatments will be described by treatment arm  
(See Section 2.1.9). 
2.4.4 Extent of investigational medicinal product exposure and compliance 
The extent of IMP exposure and compliance will be assessed and summarized by actual treatment 
within the safety population (Section 2.3.2). 
The extent of IMP exposure will be assessed by the total number of injections by patient and the 
duration of IMP injection exposure in weeks is defined as: (date of last dose of double-blind IMP 
injection + 14 days – date of first dose of double-blind IMP injection) / 7, regardless of unplanned 
intermittent discontinuations (see Section 2.5.3 for calculation in case of missing or incomplete 
data). Parameters will be summarized as quantitative variables using number, mean, SD, median, 
Q1, Q3, minimum, and maximum (non-integer values will be rounded to 1 decimal place). In 
addition, the durations of exposure will be summarized and presented graphically using bar chart 
displaying the percentage of patients according to the following categories: 1 day to <4 weeks, 
4 weeks to <8 weeks, 8 weeks to <12 weeks, 12 weeks to <16 weeks, 16 weeks and

IVRS/IWRS Week 12 transaction with at least 1 injection of alirocumab 150 mg afterwards. 
2.4.4.2 Compliance  
A given administration will be considered noncompliant if the patient did not take the planned 
dose of treatment as required by the protocol. No imputation will be made for patients with 
missing or incomplete data. 
Compliance will be assessed using the following parameters: 
x The mean injection frequency will be defined for each patient as the average number of 
days between 2 injections, that is: (last injection date – first injection date) / (number of 
injections - 1) for patients receiving at least 2 injections.

x The overall compliance for injections will be defined for each patient as: 100 – (number of 
injections performed during the study period / number of theoretical injections to be 
performed during the study period), considering that injections should be performed every 
two weeks (+/- 3 days as per protocol). 
- 
Number of theoretical injections will be defined for each patient as: [(last injection

- 
Percentage of patients who discontinued temporarily in relation with an AE, will be 
described and for these patients, the number of injections not performed per patient 
will be presented by category: 1 injection, 2 injections, 3 or more injections. 
Cases of symptomatic overdose with IMP (ie, an event that is suspected by the Investigator or 
spontaneously notified by the patient (not based on systematic injection counts), and defined as at 
least twice of the intended dose within the intended therapeutic interval (ie, 2 or more injections 
are administered in <7 calendar days)) will be specified as an AESI and will be listed and 
described as such in the AE analysis (Section 2.1.4.1). 
2.4.5 Analyses of efficacy endpoints 
For statistics where international and conventional units do not impact the results (eg, means and 
least square (LS) means for percent changes from baseline, p-values for both percent and absolute 
changes from baseline, rates of patients below a threshold), derivations will be done and statistical 
models will be run using conventional units. For other statistics (eg, descriptive statistics at 
baseline and over time, absolute changes from baseline), derivations will be done with both 
international and conventional units.  
2.4.5.1 Analysis of primary efficacy endpoint(s) 
2.4.5.1.1 Primary efficacy analysis 
Separate analyses will be performed for Type 1 diabetes patients on one hand (alpha risk = 0.05) 
and Type 2 diabetes patients on the other hand (alpha risk = 0.05), as well as in the pool 
population (alpha risk = 0.05). All outputs described below will be first described separately on 
the Type 1 diabetes patients and on the Type 2 diabetes patients, and then on the pooled data. 
The percent change in calculated LDL-C from baseline to Week 24 as defined in Section 2.1.3.1 
will be analyzed in the ITT population using a mixed effect model with repeated measures 
(MMRM) approach. All post-baseline data available within Week 8 to Week 24 analysis windows 
will be used and missing data are accounted for by the MMRM model. The model for assessing 
the treatment effect in the pooled data will include the fixed categorical effects of treatment group 
(alirocumab versus placebo), randomization strata (ie, diabetes type, as per IVRS), time point 
(Week 8, Week 12, Week 20 and Week 24), treatment group-by-time point interaction, and strata-

by time point interaction, as well as the continuous fixed covariates of baseline calculated LDL-C 
value and baseline value-by-time point interaction. The model for assessing the treatment effect 
by diabetes type will include an additional interaction term: the treatment group-by-strata-by-time 
point interaction. The significance level (P-value) of the treatment group-by-strata interaction 
term at Week 24 will be also provided for this model for descriptive purpose. In case of non-
convergence of the model, a model with less interaction terms will be fit. 
These models will be run using SAS® Mixed procedure with an unstructured correlation matrix to 
model the within-patient errors. Parameters will be estimated using restricted maximum likelihood 
method with the Newton-Raphson algorithm. Denominator degrees of freedom will be estimated 
using Satterthwaite’s approximation. This model will provide baseline adjusted LS means 
estimates at Week 24 for both treatment groups with their corresponding standard errors (SEs). To 
compare the alirocumab group to the placebo group, an appropriate contrast statement will be 
used to test the differences of these estimates, at the 2-sided 0.05 level. LS-mean difference versus 
placebo and the corresponding 95% confidence intervals (CIs) will be provided. Forest plot will 
also be provided. 
Let ȝ0 and ȝ1 be the population means of the percent change from baseline in calculated LDL-C 
at Week 24 under placebo and alirocumab, respectively. The null hypothesis that will be tested in 
each subpopulation is: 
 “H0 : ȝ0 = ȝ1” versus “H1 : ȝ0  ȝ1”. 
The MMRM model relies on the “missing-at-random” (MAR) assumption. Sensitivity analysis 
with the intent to evaluate the robustness of the primary analysis using a different statistical 
method will be conducted (see multiple imputation model definition in Section 2.4.5.1.3). As we 
can never exclude the possibility for a not-missing-at-random (NMAR) missingness mechanism, 
sensitivity analysis to explore the impact of non-ignorable missingness on the primary efficacy 
analysis will be conducted (see pattern mixture model defined in Section 2.4.5.1.3). 
2.4.5.1.2 Model assumption checks 
The following analyses will be performed by diabetes type and in the pooled data. 
Homogeneity of treatment effect across baseline calculated LDL-C levels: 
In order to check the homogeneity of treatment effect versus baseline calculated LDL-C, the 
following interaction terms will be added in the primary MMRM model: 
x Treatment group * baseline calculated LDL-C 
x Treatment group * time-point * baseline calculated LDL-C 
Within the framework of this model with interaction terms, a graph presenting the LS means 
difference versus placebo at Week 24 and the corresponding 95% CI will be provided by baseline 
calculated LDL-C value.

Analysis of residuals: 
The analysis of the residuals of the MMRM will be primarily based on studentized residuals. It 
will include: 
x Normality of studentized residuals, presented graphically using histogram and quantile 
quantile (QQ)-plot; 
x Plot of studentized residuals versus predicted values; 
2.4.5.1.3 Sensitivity to handling of missing data 
Sensitivity analyses will be conducted to assess the robustness of primary efficacy analysis with 
regards to handling of missing data (Section 2.5.3) (4). For all sensitivity analyses, outputs will be 
first described separately on the Type 1 diabetes patients and on the Type 2 diabetes patients, and 
then on the pooled data in ITT population. Forest plots will be also provided. 
Multiple imputations: 
In addition to the MMRM method, the multiple imputation method will be used to address 
missing values, in the randomized population, followed by the testing of treatment arms using an 
analysis of covariance (ANCOVA) model, with the intent to evaluate the robustness of the 
primary analysis using a different statistical method. Missing data from the randomized 
population will be imputed 100 times to generate 100 complete data sets, using the MI SAS 
procedure (using Markov Chain Monte Carlo). The percent change from baseline at Week 24 will 
be then derived from observed and imputed calculated LDL-C at this time point. The 100 
complete data sets will be then analyzed using an ANCOVA model with treatment group and 
randomization strata (as per IVRS) as fixed effects, and the baseline calculated LDL-C value as 
continuous covariate, and the MIANALYZE procedure will be used to generate valid statistical 
inferences by combining results from the 100 analyses using Rubin’s formulae (5, 6). The model 
for assessing the treatment effect by diabetes type will include an additional interaction: the 
treatment group-by-strata interaction. 
The number of imputations (100) will be informally verified by replicating sets of 100 
imputations and checking whether the combined results are stable. If not stable, the number of 
imputations will be increased and informally checked as above, and thus until stable estimates are 
obtained. 
The imputation model will include: 
x The variables included in the ANCOVA model, including the treatment group, the 
randomization strata (as per IVRS) and the baseline value. The model for assessing the 
treatment effect by diabetes type will include an additional interaction: the treatment 
group-by-strata interaction. 
x The baseline characteristics such as: age, BMI, and gender. Age and BMI will be included 
as continuous variables. 
x The calculated LDL-C values at Week 8, Week 12, Week 20 and Week 24 time points. 
Time points are those defined in Section 2.5.4.

Non continuous variables included in the imputer’s model (ie, treatment group and gender) are not 
expected to be missing. 
Pattern mixture model (see Appendix D for more details): 
Multiple imputations will be used with different imputation strategies applied to calculated LDL-
C values missing during the on-treatment period (ie, within the time period from the first double 
blind IMP injection up to the day of last injection +21 days) versus calculated LDL-C values 
missing after treatment discontinuation (ie, after the day of last injection +21 days) based on the 
following assumptions: 
x Patients within 21 days of their last blind IMP injection would continue to show benefit 
from treatment similar to that observed at the scheduled time point. Therefore, calculated 
LDL-C values missing during the on-treatment period (eg., samples obtained out-side the 
specified window, no blood sample available although visit was performed, etc.) should be 
considered “Missing At Random” and imputed based on other on-treatment 
measurements. 
x Patients who stopped taking their study treatment no longer benefited from it after 
discontinuation, and thus tended to have calculated LDL-C values returning to baseline. 
Therefore, calculated LDL-C values missing more than 21 days after treatment 
discontinuation should be imputed based on patient’s own baseline value.  
Missing calculated LDL-C values will be imputed 100 times to generate 100 complete data sets. 
The percent change from baseline to Week 24 will be derived from observed and imputed 
calculated LDL-C at this time point. The completed data sets will be analyzed using an ANCOVA 
model with treatment group and randomization strata (as per IVRS) as fixed effects, and the 
baseline calculated LDL-C value as continuous covariate. The model for assessing the treatment 
effect by diabetes type will include an additional interaction: the treatment group-by-strata 
interaction. The results from the 100 analyses will be combined using Rubin’s formulae (6). 
2.4.5.1.4 Subgroup analyses 
To assess the homogeneity of the treatment effect across various subgroups, treatment-by-
subgroup factor, time point-by-subgroup factor and treatment-by time point-by subgroup factor 
interaction terms and a subgroup factor term will be added as fixed factors in the primary MMRM 
model for the pooled data described in Section 2.4.5.1.1. For assessing the treatment effect by 
diabetes type, the same model will be fitted within each stratum, therefore without the strata factor 
and the interactions of strata with other factors. In case of non-convergence of the model, a model 
with less interaction coefficients will be fitted.  
As for the primary efficacy analysis, all outputs will be first described separately on the Type 1 
diabetes patients and on the Type 2 diabetes patients, and then on the pooled patients population. 
LS means difference versus placebo at Week 24 will be provided, as well as the corresponding 
standard error (SE) and 95% CI, within each subgroup. The significance level of the treatment-by-
subgroup factor interaction term at Week 24 will be also provided for each factor for descriptive 
purpose. Forest plots will be provided. For each subgroup analysis, subgroups will be included in

2.4.5.2 Analyses of secondary lipid efficacy endpoints 
2.4.5.2.1 Continuous endpoints anticipated to have a normal distribution 
Continuous secondary variables defined in Section 2.1.3.2 anticipated to have a normal 
distribution (eg, lipids other than TG, TGRL and Lp(a)) will be analyzed using the same MMRM 
model as for the primary endpoint. Specifically, the model for assessing the treatment effect in the 
pooled data will contain fixed categorical effects of treatment group, randomization strata (as per 
IVRS), planned time points to Week 24, treatment group-by-time point interaction, and strata-by 
time point interaction, as well as, the continuous fixed covariates of corresponding baseline value 
and baseline value-by-time point interaction. The significance level (P-value) of the treatment-by-
strata interaction term at Week 24 will be also provided for this model for descriptive purpose. In 
case of non-convergence of the model, a model with less interaction coefficients will be fitted. A 
forest plot will be provided for percent change in calculated LDL-C from baseline to week 24 on 
mITT population. 
2.4.5.2.2 Continuous endpoints anticipated to have a non-normal distribution 
Continuous secondary efficacy endpoints defined in Section 2.1.3.2, anticipated to have a non-
normal distribution (eg, TG, TGRL and Lp(a)), will be analyzed using a robust regression model 
(ie, ROBUSTREG SAS procedure with M-estimation option) with treatment group as main effect, 
and randomization strata (as per IVRS) and corresponding baseline value(s) as covariate. The 
model for assessing the treatment effect by diabetes type will also include the treatment group-by-
strata interaction. In case of non-convergence of the model, a model with less interaction 
coefficients will be fit. Missing values will be addressed using a multiple imputation model (see 
Section 2.4.5.1.3) that will at least include the same variables as used in the robust regression 
model (7). In the robust regression model, the analyzed endpoint at time point of interest will be 
derived from observed and imputed lipid values at this time point. The treatment group combined 
means will be provided with respective SE estimates. The combined mean difference between the 
treatment groups will be provided with the SE, 95% CI and p-value through the SAS 
MIANALYZE procedure. The analysis will be performed by diabetes type and on the pooled data. 
2.4.5.2.3 Binary endpoints 
Binary secondary efficacy endpoints defined in Section 2.1.3.2 (eg, proportion of patients below a 
threshold) will be analyzed using logistic regression with treatment group as main effect and 
corresponding baseline value(s) as covariate, stratified by randomization strata. Missing values 
will be addressed using a multiple imputation approach (see Section 2.4.5.1.3). The variables in 
the multiple imputation model will at least include the same variables as used in the logistic 
regression model. In the logistic regression model, the analyzed endpoint at time point of interest 
will be derived from observed and imputed lipid values at this time point. Treatment effects will 
be compared and the combined odds ratio estimate between the treatment groups, with their

corresponding 95% CIs and p-value will be provided via the SAS MIANALYZE procedure. The 
analysis will be performed by diabetes type and on the pooled data. 
In the data dependent case that the logistic regression method is not applicable (eg, the response 
rate is zero in 1 treatment arm and thus the maximum likelihood estimate may not exist), the last 
observation carried forward (LOCF) approach would be used for handling of missing values and 
an exact conditional logistic regression would be performed to compare treatment effects. The 
LOCF imputation method will consist of using the last value obtained up to the Week 24 analysis 
window (or Week 12 as applicable) to impute the missing week 24 value (or Week 12 
respectively). 
In case of computing issues with exact logistic regression, the baseline level(s) will be entered in 
the model as a categorical variable(s) using quartiles. Exact odds ratio versus placebo, 95% CI, 
and p-value will be provided. 
2.4.5.2.4 Summary of results per time point 
Central laboratory values (in conventional (US) and international units), percent change from 
baseline and/or when appropriate absolute change from baseline (in conventional and 
international units) in calculated LDL-C, measured LDL-C, HDL-C, fasting TG, non-HDL-C, TC, 
ratio TC/HDL-C, Lp(a), Apo B, Apo A-1, ratio Apo B/Apo A-1, Apo C-III, TGRL, LDL-C 
particle size, LDL-C particle number will be provided at each time point for each treatment group 
in the ITT population using: 
x For lipids other than TG, TGRL and Lp(a): LS mean and SE for each treatment group, 
obtained from the same MMRM models as used for endpoints above and including 
planned time points (see Section 2.4.5.2.1) and with raw values, changes from baseline, or 
percent change from baseline as response variable in the model as appropriate. 
x For TG, TGRL and Lp(a): combined mean and SE for each treatment group obtained from 
multiple imputation approach followed by the robust regression models as used for 
endpoints above and including planned time points (see Section 2.4.5.2.2) and with raw 
values or percent changes from baseline as response variable in the model as appropriate. 
All measurements, scheduled or unscheduled will be assigned to analysis windows  
(see Section 2.5.4 on which value to select) in order to provide an assessment for these time 
points. Laboratory assessments other than the ones provided by the central laboratory will be 
excluded.  
Summary tables and graphs over time of each parameter will be plotted by treatment group (LS 
mean + SEs by time point). The analysis will be performed by diabetes type and on the pooled 
data. 
In addition, quantitative descriptive summaries by time point for each treatment group (value at 
visit and % change from baseline, or when appropriate absolute change from baseline) will be 
presented for all lipids using observed (ie, non-missing) data, and binary variables for LDL-C will 
be also provided in summary tables. These analyses will be performed by diabetes type and on the 
pooled data.

Calculated LDL-C will be described and plotted according to up-titration status. ie, according to 
whether the patients remained on the 75 mg dose or whether they were up-titrated to 150 mg.  
2.4.5.2.5 Sensitivity analysis for the computation of TGRL values 
Two sensitivity analyses will be performed to assess the impact of the computation of TGRL 
values on the effect of treatment: 
1. In the first sensitivity computation, TGRL will be computed from measured LDL-C 
only, not replaced by calculated LDL-C in case of missing value of measured LDL-C. 
2. In the second sensitivity computation, TGRL will be computed from fasting samples 
only, ie, non-fasting samples will be excluded from analysis. 
For both sensitivity computations, the percent change from baseline to Weeks 12 and 24 (ITT and 
on-treatment estimands) will be assessed in the same way than for the main computation of 
TGRL, using the model described in Section 2.4.5.2.2. 
2.4.5.3 Multiplicity issues 
In order to handle multiple key secondary efficacy endpoints, the overall type-I error will be 
controlled by the use of a sequential inferential approach. Statistical significance of the primary 
parameter at the 0.05 alpha level is required before drawing inferential conclusions about first key 
secondary parameter (refer to order in Section 2.1.3.2.1). 
Inferential conclusions about successive key secondary efficacy parameters require statistical 
significance of the prior one. This fixed hierarchical approach will ensure a strong control of the 
overall type-I error rate at the 0.05 level. 
No further adjustments will be made for other efficacy endpoints for which p-values will be 
provided for descriptive purpose only. 
2.4.5.4 Additional efficacy analysis: region North America 
Additional efficacy analyses on selected endpoints will also be replicated in the subgroup of 
patients of the region North America.  
2.4.6 Analyses of safety data 
The summary of safety results will be presented by actual treatment group. Summaries will be 
descriptive in nature. Safety analysis will be performed by diabetes type and in the pooled data.

General common rules 
All safety analyses will be performed on the safety population as defined in Section 2.3.2, using 
the following common rules: 
x Safety data in patients who do not belong to the safety population (eg, exposed but not 
randomized or re-randomized patients) will be listed separately. 
x 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 (PCSA version dated January 2009 [Appendix A]). 
x 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 number of all such patients will be the 
numerator for the on-treatment PCSA percentage. 
x The treatment-emergent PCSA denominator by group for a given parameter will be based 
on the number of patients assessed for that given parameter in the TEAE period by 
treatment group on the safety population. 
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 0 to Week 32 time 
points. 
x For quantitative safety parameters based on central laboratory 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 (see Section 2.1.4). The worst on-treatment 
value is defined as the nadir and /or the peak value during the treatment period according 
to the direction (minimum or maximum) of the abnormality as defined in the PCSA list.  
x For exploratory purpose, all TEAEs will be described by SOC, HLGT, HLT and PT 
according to up-titration status, ie, according to whether the patients remained on the 75 
mg dose or whether they were up-titrated to 150 mg. These analyses will be exploratory 
and descriptive (no formal comparison per dose) as it is expected that there could be 
inherent differences in the baseline characteristics between those patients titrating to 150 
mg and those remaining on 75 mg. In order to reduce the bias of this analysis, the period 
before the up-titration time point (planned at Week 12) will be analyzed separately since 
only the dose 75 mg is proposed for this time period and consequently the early events 
occurring before Week 12 can only be attributed to this dose. Therefore the descriptive 
analysis per dose will include any safety events occurring from the first injection post 
Week 12 IVRS/IWRS transaction to the end of the TEAE period. Baseline characteristics 
of patients receiving each dose will be summarized.

2.4.6.1 Analyses of adverse events 
Generalities 
The primary focus of AE 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 pre-treatment, 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-
treatment 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. The denominator for computation of percentages is the safety population within 
each treatment group. 
Sorting within tables ensures the same presentation for the set of all AEs within the observation 
period (pre-treatment, treatment-emergent, 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 alirocumab group) will define the presentation order for all 
other tables 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 TEAEs summaries will be generated for the safety population. 
x Overview of TEAEs, summarizing number (%) of patients with any 
- 
TEAE; 
- 
Serious TEAE; 
- 
TEAE leading to death; 
- 
TEAE leading to permanent treatment discontinuation. 
x Number (%) of patients experiencing TEAEs by primary SOC, HLGT, HLT, and PT; 
x Number (%) of patients experiencing common TEAE(s) presented by primary SOC, HLT

agreed order and by alphabetic order for the other levels (HLT and PT); 
x Number of patients experiencing TEAEs by primary SOC and PT, sorted by the 
internationally agreed SOC order and by decreasing incidence of PTs within each SOC (in 
the alirocumab group). This order will be applied to all other TEAEs tables by SOC and 
PT, unless otherwise specified;

2.4.6.2 Deaths 
The following summaries of deaths will be generated for the safety population. 
x Number (%) of patients who died by study period (on-study, on-treatment, post-study); 
x Deaths in non-randomized patients or randomized but not treated patients 
x Treatment-emergent AEs leading to death (death as an outcome on the AE e-CRF page as 
reported by the Investigator) by primary SOC and PT showing number (%) of patients 
sorted by internationally agreed SOC order, with PT presented in alphabetical order within 
each SOC. TEAE leading to death are TEAE that led to death regardless of timing of death 
in relation to IMP injection (ie, death occurring in the TEAE period or during the post-
treatment period). 
x All deaths will be listed. 
2.4.6.3 Analyses of laboratory variables 
The summary statistics (including number, mean, standard deviation, median, Q1, Q3, 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 value of the 
treatment period, last on-treatment and/or worst on-treatment) by treatment group, by diabetes 
type and in the pooled data. In addition, for some parameters of interest, mean changes from 
baseline with the corresponding SE could be plotted over time (at same time points) in each 
treatment group. This section will be organized by biological function as specified in  
Section 2.1.4.3. For glucose, only fasting samples will be summarized. 
The incidence of PCSAs (list provided in Appendix A) at any time during the TEAE period will 
be summarized by treatment group whatever the baseline level and/or according to the following 
baseline status categories: 
x Normal/missing 
x 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. 
Glucose (quantitative summary and PCSA) will also be analyzed, by diabetes type and in the 
pooled data.  
If any clinically significant signal is detected and needs further characterization, exploration of 
time to onset will be performed for selected PCSAs assessed during the TEAE period as described 
below to account for the differential exposure time in all patients. 
The incidence rates of selected PCSA during TEAE period at 24 weeks of exposure will be 
calculated with Kaplan-Meier methodology, using the midpoint of the time interval between the 
first assessment with PCSA and the previous assessment. Kaplan-Meier curves will be also 
provided. Only the first event (PCSA) will be counted. Patients without any event will be 
censored at the last assessment performed during the TEAE period.

The baseline evaluation will be based on tests performed during the pre-treatment period. 
If no Ab test is available or with “indeterminate” as result pre-treatment or post-baseline, 
respectively, the RNA test (if available) will be used alone to determine the status of the patient. If 
no RNA is available then the hepatitis C status of the patient will be missing. 
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 AESI section (see Section 2.1.4.1) at any post-baseline visit by baseline status will be 
displayed by treatment group for each parameter. 
An evaluation of drug-induced serious hepatotoxicity (eDISH) 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 are 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 by treatment group (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, GGT, 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 2.4.5.1). Time to liver-related treatment 
discontinuation will be analyzed using Kaplan-Meier estimates presented by treatment group. 
2.4.6.4 Analyses of vital sign variables 
The summary statistics (including number, mean, standard deviation, median, Q1, Q3, minimum 
and maximum) of all vital signs variables (raw values and changes from baseline) will be 
calculated for each visit or study assessment (baseline, each post-baseline value of the treatment 
period, last on-treatment and/or worst on-treatment and follow-up visit) by treatment group. In 
addition for some parameters of interest; mean changes from baseline with the corresponding SE 
could be plotted over time (at same time points) in each treatment group. 
The incidence of PCSAs at any time during the TEAE period will be summarized by treatment 
group. 
If any clinically significant signal is detected and needs further characterization, exploration of 
time to onset will be performed for selected PCSAs assessed during the TEAE period as described 
below to account for the differential exposure time in all patients. 
The incidence rates of selected PCSA during TEAE period at 24 weeks of exposure will be

positive ADA by time point and by treatment group and also according to up-titration 
status; 
x Number (%) of patients with pre-existing ADA and number (%) of patients with 
treatment-emergent ADA positive response by treatment group, overall and according to 
up-titration status;

positive response by treatment group, overall and according to up-titration status; 
x Time to onset of treatment-emergent ADA positive response using descriptive statistics by 
treatment group, overall and according to up-titration status. 
Correlations between ADA parameters (eg, titers, status, neutralizing status) and calculated LDL-
C will be also explored (eg, box plot, scatter plot): 
x % change from baseline in calculated LDL-C vs neutralizing negative/positive ADA status 
at last value up to Week 24 
x % change from baseline in calculated LDL-C vs persistent/transient/indeterminate 
treatment-emergent ADA positive response at last value up to Week 24

DATA HANDLING CONVENTIONS 
2.5.1 Conventions 
The following formulas will be used for computation of parameters. 
Time since event / duration  
Time since [event]/duration (years) = (Date of informed consent – Date of [event]1) / 365.25. 
[event] can be quit smoking, menopause. Duration can be for diabetes, hypercholesterolemia, 
insulin use, hypertension... 
Date of last dose of IMP 
The date of the last injection is equal to the last date of administration reported on injection 
administration e-CRF page, or missing if the last administration date is unknown. 
HbA1c formula  
The master equation for converting National Glycohemoglobin Standardization Program (NGSP) 
units into International Federation of Clinical Chemistry (IFCC) units (8) is: 
HbA1c mmol/mol = 10.93 x HbA1c% - 23.5 
Renal function formulas  
Estimated GFR (estimated Glomerular Filtration Rate) value will be derived using the 
Modification of Diet in Renal Disease (MDRD) equation: 
186.3 × (creatinine in μmol/L / 88.4)-1.154 × (age in years)-0.203 (x 0.742 if female, x 1.21 if race is 
"black or african american"). 
Lipids variables and laboratory safety variables 
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 (ULOQ)/limit of linearity, the upper limit value (ie, ULOQ) will be used for 
quantitative analyses. 
2.5.2 Data handling conventions for secondary efficacy variables 
See Section 2.4.5.2. 
                                                 
1 In case the month of event would be missing, it will be put equal to JANUARY if the year of event equals 
the year of informed consent; it will be put equal to JULY otherwise. In case the day of event would be 
missing, it will be put equal to 1.

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 double-blind administration or time of 
assessment at Week 0 visit is missing 
If the time of the first double-blind administration or time of assessment at Week 0 visit is missing 
then the baseline value is defined as the last available value obtained before (ie, at an unscheduled 
visit) or on the day of the first double-blind IMP administration. 
Handling of computation of treatment duration if investigational medicinal product first or end 
of treatment date is missing 
If the last or first injection date is missing, the exposure duration and compliance will be left as 
missing. 
Handling of safety and efficacy analysis periods and survival analysis if investigational 
medicinal product end of treatment date is missing 
If the last injection date is missing, then this date is imputed to the earliest between: 
x The last day of the month and year, when applicable or else the 31st of December of the 
year; 
x The date of the end of treatment visit (Week 24 visit for completer, early end of treatment 
visit for patients who prematurely discontinued the IMP); 
x And the date of the last contact; 
for the purpose of safety and efficacy analysis period start and/or 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 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 AE 
resolution.

Page 55 
Handling of adverse events when date and time of first investigational medicinal product 
administration is missing 
When the date and time of the first IMP administration is missing, all AEs that occurred on or 
after the day of randomization will be considered as TEAEs. 
When the time of the first double-blind IMP administration is missing, all AEs that occurred on 
the day of the first double-blind IMP administration will be considered as treatment-emergent 
AEs. 
Handling of missing assessment of relationship of adverse events to investigational medicinal 
product 
If the assessment of the relationship to IMP is missing, then the relationship to IMP has to be 
assumed as possibly related in the frequency tables, but no imputation should be done at the data 
level. 
Handling of potentially clinically significant abnormalities 
If a patient has a missing baseline value he will be grouped in the category “normal/missing at 
baseline.” 
For PCSAs with two conditions: 
x The first one based on a change from baseline value  
x The other one based on a threshold value or a normal range,  
If the first condition is missing, PCSA will be only based on the second condition. 
For a PCSA defined on a threshold value and/or a normal range, it will be derived using this 
threshold if the normal range is missing; eg, for eosinophils, if no ULN is available or if ULN is 
<0.5 GIGA/L then the PCSA is >0.5 GIGA/L, while if ULN is available and 0.5 GIGA/L then 
the PCSA is >ULN.  
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 (including efficacy, laboratory safety data, vital signs,
 ADA) 
will be summarized using the analysis windows given in Table 2. These analysis windows will be 
applicable for all analyses, and they are defined to provide more homogeneous data for time 
point-specific analyses.

Study days are calculated from the day of first double-blind IMP, the day of first double-blind 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 efficacy, 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.

INTERIM ANALYSIS 
No formal interim analysis for efficacy is planned since analysis of primary and key secondary 
efficacy endpoints will be final at the time of first-step analysis described below. All efficacy data 
will be available for final analysis at a cut-off date corresponding to the Week 24 visit of the last 
patient, and both the efficacy and safety analyses will be performed in a first-step analysis. Since 
safety data are collected until the end of the study (Week 32), an update of the safety analysis will 
be performed in a second-step analysis at the end of the study. 
The first-step analysis will be conducted as soon as all patients have been randomized and have at 
least all their data up to Week 24 analysis window collected and validated. It will consist of a final 
analysis of the primary and secondary efficacy endpoints up to Week 24, as well as safety analysis 
performed on all safety data collected up to the common cut-off date, defined as the date of the 
last Week 24 visit.  
The second-step analysis will be conducted at the end of the study and will consist in the updated 
analysis of safety endpoints until Week 32. No multiplicity adjustment for multiple analyses is 
needed because all efficacy analyses will be completed at the time of the first-step analysis. 
Selected individuals who are not involved in the conduct of the study after the first step analysis 
will perform the second step analysis; individual patient identification will not be released to 
anyone who is directly involved in the ongoing conduct of the study. 
Analyses methods and conventions described in the other sections of this SAP will be applied for 
all analyses as applicable. The following additional rules will apply for analyses performed at 
first step analysis:  
x Any lipid assessments within analysis windows up to Week 24 will be taken into account 
(may include few unscheduled lipid data soon after the cut-off date). 
x Patients without end of treatment visit performed at the time of the cut-off date will be 
considered as ongoing and exposed up to the cut-off date. Therefore:  
- 
Patients who did not complete treatment period nor prematurely discontinued the study 
treatment at cut-off date will be analyzed as “ongoing” in the disposition summary; 
- 
Their TEAE period, treatment period and on-study observation period will end at the 
cut-off date; 
- 
Their treatment duration will be derived by considering date of cut-off as last injection 
date and last capsule date. 
x Analyses of number of injections, mean injection frequency, percentage of days with 
under/above-planned dosing and compliance (for injections and capsules) will be 
performed up to the last injection and capsule reported in the e-CRF up to the cut-off date. 
x AEs occurring, worsening or becoming serious after the cut-off date will not be included 
in the analyses. However, any available outcome before database lock, regardless of 
timing in relation to the cut-off date, of an AE starting prior to the cut-off date will be 
taken into account. Medications, treatment discontinuations/completions, and deaths 
occurring after the cut-off date will not be included in the analyses.

x Post-treatment period, post-study period are not applicable for ongoing patients. Analyses 
of post-treatment AEs, post-study deaths, and post-treatment medications will be 
performed for patients who either completed or prematurely discontinued the treatment 
before or at the cut-off date. 
x Analysis of status at last study contact and proportion of patients with insufficient follow-
up will be provided for patients who either completed or prematurely discontinued the 
treatment before or at the cut-off date.
